Merge branch 'next-integrity' of git://git.kernel.org/pub/scm/linux/kernel/git/zohar/linux-integrity
Pull integrity updates from Mimi Zohar:
"Bug fixes, code clean up, and new features:
- IMA policy rules can be defined in terms of LSM labels, making the
IMA policy dependent on LSM policy label changes, in particular LSM
label deletions. The new environment, in which IMA-appraisal is
being used, frequently updates the LSM policy and permits LSM label
deletions.
- Prevent an mmap'ed shared file opened for write from also being
mmap'ed execute. In the long term, making this and other similar
changes at the VFS layer would be preferable.
- The IMA per policy rule template format support is needed for a
couple of new/proposed features (eg. kexec boot command line
measurement, appended signatures, and VFS provided file hashes).
- Other than the "boot-aggregate" record in the IMA measuremeent
list, all other measurements are of file data. Measuring and
storing the kexec boot command line in the IMA measurement list is
the first buffer based measurement included in the measurement
list"
* 'next-integrity' of git://git.kernel.org/pub/scm/linux/kernel/git/zohar/linux-integrity:
integrity: Introduce struct evm_xattr
ima: Update MAX_TEMPLATE_NAME_LEN to fit largest reasonable definition
KEXEC: Call ima_kexec_cmdline to measure the boot command line args
IMA: Define a new template field buf
IMA: Define a new hook to measure the kexec boot command line arguments
IMA: support for per policy rule template formats
integrity: Fix __integrity_init_keyring() section mismatch
ima: Use designated initializers for struct ima_event_data
ima: use the lsm policy update notifier
LSM: switch to blocking policy update notifiers
x86/ima: fix the Kconfig dependency for IMA_ARCH_POLICY
ima: Make arch_policy_entry static
ima: prevent a file already mmap'ed write to be mmap'ed execute
x86/ima: check EFI SetupMode too

+Description: This file allows the driver for a device to be specified. When
+ specified, only a driver with a name matching the value written
+ to driver_override will have an opportunity to bind to the
+ device. The override is specified by writing a string to the
+ driver_override file (echo vfio-ccw > driver_override) and
+ may be cleared with an empty string (echo > driver_override).
+ This returns the device to standard matching rules binding.
+ Writing to driver_override does not automatically unbind the
+ device from its current driver or make any attempt to
+ automatically load the specified driver. If no driver with a
+ matching name is currently loaded in the kernel, the device
+ will not bind to any driver. This also allows devices to
+ opt-out of driver binding using a driver_override name such as
+ "none". Only a single driver may be specified in the override,
+ there is no support for parsing delimiters.
+ Note that unlike the mechanism of the same name for pci, this
+ file does not allow to override basic matching rules. I.e.,
+ the driver must still match the subchannel type of the device.

HOWTO
=====
-Proportional Weight division of bandwidth
------------------------------------------
-You can do a very simple testing of running two dd threads in two different
-cgroups. Here is what you can do.
-
-- Enable Block IO controller
- CONFIG_BLK_CGROUP=y
-
-- Enable group scheduling in CFQ
- CONFIG_CFQ_GROUP_IOSCHED=y
-
-- Compile and boot into kernel and mount IO controller (blkio); see
- cgroups.txt, Why are cgroups needed?.
-
- mount -t tmpfs cgroup_root /sys/fs/cgroup
- mkdir /sys/fs/cgroup/blkio
- mount -t cgroup -o blkio none /sys/fs/cgroup/blkio
-
-- Create two cgroups
- mkdir -p /sys/fs/cgroup/blkio/test1/ /sys/fs/cgroup/blkio/test2
-
-- Set weights of group test1 and test2
- echo 1000 > /sys/fs/cgroup/blkio/test1/blkio.weight
- echo 500 > /sys/fs/cgroup/blkio/test2/blkio.weight
-
-- Create two same size files (say 512MB each) on same disk (file1, file2) and
- launch two dd threads in different cgroup to read those files.
-
- sync
- echo 3 > /proc/sys/vm/drop_caches
-
- dd if=/mnt/sdb/zerofile1 of=/dev/null &
- echo $! > /sys/fs/cgroup/blkio/test1/tasks
- cat /sys/fs/cgroup/blkio/test1/tasks
-
- dd if=/mnt/sdb/zerofile2 of=/dev/null &
- echo $! > /sys/fs/cgroup/blkio/test2/tasks
- cat /sys/fs/cgroup/blkio/test2/tasks
-
-- At macro level, first dd should finish first. To get more precise data, keep
- on looking at (with the help of script), at blkio.disk_time and
- blkio.disk_sectors files of both test1 and test2 groups. This will tell how
- much disk time (in milliseconds), each group got and how many sectors each
- group dispatched to the disk. We provide fairness in terms of disk time, so
- ideally io.disk_time of cgroups should be in proportion to the weight.

-=================
-/sys/block/<disk>/queue/iosched/slice_idle
-------------------------------------------
-On a faster hardware CFQ can be slow, especially with sequential workload.
-This happens because CFQ idles on a single queue and single queue might not
-drive deeper request queue depths to keep the storage busy. In such scenarios
-one can try setting slice_idle=0 and that would switch CFQ to IOPS
-(IO operations per second) mode on NCQ supporting hardware.
-
-That means CFQ will not idle between cfq queues of a cfq group and hence be
-able to driver higher queue depth and achieve better throughput. That also
-means that cfq provides fairness among groups in terms of IOPS and not in
-terms of disk time.
-
-/sys/block/<disk>/queue/iosched/group_idle
-------------------------------------------
-If one disables idling on individual cfq queues and cfq service trees by
-setting slice_idle=0, group_idle kicks in. That means CFQ will still idle
-on the group in an attempt to provide fairness among groups.
-
-By default group_idle is same as slice_idle and does not do anything if
-slice_idle is enabled.
-
-One can experience an overall throughput drop if you have created multiple
-groups and put applications in that group which are not driving enough
-IO to keep disk busy. In that case set group_idle=0, and CFQ will not idle
-on individual groups and throughput should improve.

+- compatible: should be "amazon,al-fic"
+- reg: physical base address and size of the registers
+- interrupt-controller: identifies the node as an interrupt controller
+- #interrupt-cells: must be 2.
+ First cell defines the index of the interrupt within the controller.
+ Second cell is used to specify the trigger type and must be one of the

+DT compatible string versioning for SiFive open-source IP blocks
+
+This document describes the version specification for DT "compatible"
+strings for open-source SiFive IP blocks. HDL for these IP blocks
+can be found in this public repository:
+
+https://github.com/sifive/sifive-blocks
+
+IP block-specific DT compatible strings are contained within the HDL,
+in the form "sifive,<ip-block-name><integer version number>".
+
+An example is "sifive,uart0" from:
+
+https://github.com/sifive/sifive-blocks/blob/v1.0/src/main/scala/devices/uart/UART.scala#L43
+
+Until these IP blocks (or IP integration) support version
+auto-discovery, the maintainers of these IP blocks intend to increment
+the suffixed number in the compatible string whenever the software
+interface to these IP blocks changes, or when the functionality of the
+underlying IP blocks changes in a way that software should be aware of.
+
+Driver developers can use compatible string "match" values such as
+"sifive,uart0" to indicate that their driver is compatible with the
+register interface and functionality associated with the relevant
+upstream sifive-blocks commits. It is expected that most drivers will
+match on these IP block-specific compatible strings.
+
+DT data authors, when writing data for a particular SoC, should
+continue to specify an SoC-specific compatible string value, such as
+"sifive,fu540-c000-uart". This way, if SoC-specific
+integration-specific bug fixes or workarounds are needed, the kernel
+or other system software can match on this string to apply them. The
+IP block-specific compatible string (such as "sifive,uart0") should
+then be specified as a subsequent value.
+
+An example of this style:
+
+ compatible = "sifive,fu540-c000-uart", "sifive,uart0";

+ If AVX512 is supported on the machine, this entry shows the milliseconds

+ happens on a best effort basis when a task is scheduled out. This means
+ that the value depends on two factors:
+
+ 1) The time which the task spent on the CPU without being scheduled
+ out. With CPU isolation and a single runnable task this can take
+ several seconds.
+
+ 2) The time since the task was scheduled out last. Depending on the
+ reason for being scheduled out (time slice exhausted, syscall ...)
+ this can be arbitrary long time.
+
+ As a consequence the value cannot be considered precise and authoritative
+ information. The application which uses this information has to be aware
+ of the overall scenario on the system in order to determine whether a
+ task is a real AVX512 user or not. Precise information can be obtained
+ with performance counters.
+
+ A special value of '-1' indicates that no AVX512 usage was recorded, thus
+ the task is unlikely an AVX512 user, but depends on the workload and the
+ scheduling scenario, it also could be a false negative mentioned above.

If you want to only see part of the traffic, you can program the
NIC through ethtool to filter out your traffic to a single queue id
that you can bind your XDP socket to. Here is one example in which
UDP traffic to and from port 4242 are sent to queue 2::

the NIC you have.

+Kernel TLS offload
+==================
+
+Kernel TLS operation
+====================
+
+Linux kernel provides TLS connection offload infrastructure. Once a TCP
+connection is in ``ESTABLISHED`` state user space can enable the TLS Upper
+Layer Protocol (ULP) and install the cryptographic connection state.
+For details regarding the user-facing interface refer to the TLS
+documentation in :ref:`Documentation/networking/tls.rst <kernel_tls>`.
+
+``ktls`` can operate in three modes:
+
+ * Software crypto mode (``TLS_SW``) - CPU handles the cryptography.
+ In most basic cases only crypto operations synchronous with the CPU
+ can be used, but depending on calling context CPU may utilize
+ asynchronous crypto accelerators. The use of accelerators introduces extra
+ latency on socket reads (decryption only starts when a read syscall
+ is made) and additional I/O load on the system.
+ * Packet-based NIC offload mode (``TLS_HW``) - the NIC handles crypto
+ on a packet by packet basis, provided the packets arrive in order.
+ This mode integrates best with the kernel stack and is described in detail
+ in the remaining part of this document
+ (``ethtool`` flags ``tls-hw-tx-offload`` and ``tls-hw-rx-offload``).
+ * Full TCP NIC offload mode (``TLS_HW_RECORD``) - mode of operation where
+ NIC driver and firmware replace the kernel networking stack
+ with its own TCP handling, it is not usable in production environments
+ making use of the Linux networking stack for example any firewalling
+ abilities or QoS and packet scheduling (``ethtool`` flag ``tls-hw-record``).
+
+The operation mode is selected automatically based on device configuration,
+offload opt-in or opt-out on per-connection basis is not currently supported.
+
+TX
+--
+
+At a high level user write requests are turned into a scatter list, the TLS ULP
+intercepts them, inserts record framing, performs encryption (in ``TLS_SW``
+mode) and then hands the modified scatter list to the TCP layer. From this
+point on the TCP stack proceeds as normal.
+
+In ``TLS_HW`` mode the encryption is not performed in the TLS ULP.
+Instead packets reach a device driver, the driver will mark the packets
+for crypto offload based on the socket the packet is attached to,
+and send them to the device for encryption and transmission.
+
+RX
+--
+
+On the receive side if the device handled decryption and authentication
+successfully, the driver will set the decrypted bit in the associated
+:c:type:`struct sk_buff <sk_buff>`. The packets reach the TCP stack and
+are handled normally. ``ktls`` is informed when data is queued to the socket
+and the ``strparser`` mechanism is used to delineate the records. Upon read
+request, records are retrieved from the socket and passed to decryption routine.
+If device decrypted all the segments of the record the decryption is skipped,
+otherwise software path handles decryption.

+ Layers of Kernel TLS stack
+
+Device configuration
+====================
+
+During driver initialization device sets the ``NETIF_F_HW_TLS_RX`` and
+``NETIF_F_HW_TLS_TX`` features and installs its
+:c:type:`struct tlsdev_ops <tlsdev_ops>`
+pointer in the :c:member:`tlsdev_ops` member of the
+:c:type:`struct net_device <net_device>`.
+
+When TLS cryptographic connection state is installed on a ``ktls`` socket
+(note that it is done twice, once for RX and once for TX direction,
+and the two are completely independent), the kernel checks if the underlying
+network device is offload-capable and attempts the offload. In case offload
+fails the connection is handled entirely in software using the same mechanism
+as if the offload was never tried.
+
+Offload request is performed via the :c:member:`tls_dev_add` callback of
+:c:type:`struct tlsdev_ops <tlsdev_ops>`:
+
+.. code-block:: c
+
+ int (*tls_dev_add)(struct net_device *netdev, struct sock *sk,
+ enum tls_offload_ctx_dir direction,
+ struct tls_crypto_info *crypto_info,
+ u32 start_offload_tcp_sn);
+
+``direction`` indicates whether the cryptographic information is for
+the received or transmitted packets. Driver uses the ``sk`` parameter
+to retrieve the connection 5-tuple and socket family (IPv4 vs IPv6).
+Cryptographic information in ``crypto_info`` includes the key, iv, salt
+as well as TLS record sequence number. ``start_offload_tcp_sn`` indicates
+which TCP sequence number corresponds to the beginning of the record with
+sequence number from ``crypto_info``. The driver can add its state
+at the end of kernel structures (see :c:member:`driver_state` members
+in ``include/net/tls.h``) to avoid additional allocations and pointer
+dereferences.
+
+TX
+--
+
+After TX state is installed, the stack guarantees that the first segment
+of the stream will start exactly at the ``start_offload_tcp_sn`` sequence
+number, simplifying TCP sequence number matching.
+
+TX offload being fully initialized does not imply that all segments passing
+through the driver and which belong to the offloaded socket will be after
+the expected sequence number and will have kernel record information.
+In particular, already encrypted data may have been queued to the socket
+before installing the connection state in the kernel.
+
+RX
+--
+
+In RX direction local networking stack has little control over the segmentation,
+so the initial records' TCP sequence number may be anywhere inside the segment.
+
+Normal operation
+================
+
+At the minimum the device maintains the following state for each connection, in
+each direction:
+
+ * crypto secrets (key, iv, salt)
+ * crypto processing state (partial blocks, partial authentication tag, etc.)
+ * record metadata (sequence number, processing offset and length)
+ * expected TCP sequence number
+
+There are no guarantees on record length or record segmentation. In particular
+segments may start at any point of a record and contain any number of records.
+Assuming segments are received in order, the device should be able to perform
+crypto operations and authentication regardless of segmentation. For this
+to be possible device has to keep small amount of segment-to-segment state.
+This includes at least:
+
+ * partial headers (if a segment carried only a part of the TLS header)
+ * partial data block
+ * partial authentication tag (all data had been seen but part of the
+ authentication tag has to be written or read from the subsequent segment)
+
+Record reassembly is not necessary for TLS offload. If the packets arrive
+in order the device should be able to handle them separately and make
+forward progress.
+
+TX
+--
+
+The kernel stack performs record framing reserving space for the authentication
+tag and populating all other TLS header and tailer fields.
+
+Both the device and the driver maintain expected TCP sequence numbers
+due to the possibility of retransmissions and the lack of software fallback
+once the packet reaches the device.
+For segments passed in order, the driver marks the packets with
+a connection identifier (note that a 5-tuple lookup is insufficient to identify
+packets requiring HW offload, see the :ref:`5tuple_problems` section)
+and hands them to the device. The device identifies the packet as requiring
+TLS handling and confirms the sequence number matches its expectation.
+The device performs encryption and authentication of the record data.
+It replaces the authentication tag and TCP checksum with correct values.
+
+RX
+--
+
+Before a packet is DMAed to the host (but after NIC's embedded switching
+and packet transformation functions) the device validates the Layer 4
+checksum and performs a 5-tuple lookup to find any TLS connection the packet
+may belong to (technically a 4-tuple
+lookup is sufficient - IP addresses and TCP port numbers, as the protocol
+is always TCP). If connection is matched device confirms if the TCP sequence
+number is the expected one and proceeds to TLS handling (record delineation,
+decryption, authentication for each record in the packet). The device leaves
+the record framing unmodified, the stack takes care of record decapsulation.
+Device indicates successful handling of TLS offload in the per-packet context
+(descriptor) passed to the host.
+
+Upon reception of a TLS offloaded packet, the driver sets
+the :c:member:`decrypted` mark in :c:type:`struct sk_buff <sk_buff>`
+corresponding to the segment. Networking stack makes sure decrypted
+and non-decrypted segments do not get coalesced (e.g. by GRO or socket layer)
+and takes care of partial decryption.
+
+Resync handling
+===============
+
+In presence of packet drops or network packet reordering, the device may lose
+synchronization with the TLS stream, and require a resync with the kernel's
+TCP stack.
+
+Note that resync is only attempted for connections which were successfully
+added to the device table and are in TLS_HW mode. For example,
+if the table was full when cryptographic state was installed in the kernel,
+such connection will never get offloaded. Therefore the resync request
+does not carry any cryptographic connection state.
+
+TX
+--
+
+Segments transmitted from an offloaded socket can get out of sync
+in similar ways to the receive side-retransmissions - local drops
+are possible, though network reorders are not.
+
+Whenever an out of order segment is transmitted the driver provides
+the device with enough information to perform cryptographic operations.
+This means most likely that the part of the record preceding the current
+segment has to be passed to the device as part of the packet context,
+together with its TCP sequence number and TLS record number. The device
+can then initialize its crypto state, process and discard the preceding
+data (to be able to insert the authentication tag) and move onto handling
+the actual packet.
+
+In this mode depending on the implementation the driver can either ask
+for a continuation with the crypto state and the new sequence number
+(next expected segment is the one after the out of order one), or continue
+with the previous stream state - assuming that the out of order segment
+was just a retransmission. The former is simpler, and does not require
+retransmission detection therefore it is the recommended method until
+such time it is proven inefficient.
+
+RX
+--
+
+A small amount of RX reorder events may not require a full resynchronization.
+In particular the device should not lose synchronization
+when record boundary can be recovered:
+
+.. kernel-figure:: tls-offload-reorder-good.svg
+ :alt: reorder of non-header segment
+ :align: center
+
+ Reorder of non-header segment
+
+Green segments are successfully decrypted, blue ones are passed
+as received on wire, red stripes mark start of new records.
+
+In above case segment 1 is received and decrypted successfully.
+Segment 2 was dropped so 3 arrives out of order. The device knows
+the next record starts inside 3, based on record length in segment 1.
+Segment 3 is passed untouched, because due to lack of data from segment 2
+the remainder of the previous record inside segment 3 cannot be handled.
+The device can, however, collect the authentication algorithm's state
+and partial block from the new record in segment 3 and when 4 and 5
+arrive continue decryption. Finally when 2 arrives it's completely outside
+of expected window of the device so it's passed as is without special
+handling. ``ktls`` software fallback handles the decryption of record
+spanning segments 1, 2 and 3. The device did not get out of sync,
+even though two segments did not get decrypted.
+
+Kernel synchronization may be necessary if the lost segment contained
+a record header and arrived after the next record header has already passed:
+
+.. kernel-figure:: tls-offload-reorder-bad.svg
+ :alt: reorder of header segment
+ :align: center
+
+ Reorder of segment with a TLS header
+
+In this example segment 2 gets dropped, and it contains a record header.
+Device can only detect that segment 4 also contains a TLS header
+if it knows the length of the previous record from segment 2. In this case
+the device will lose synchronization with the stream.
+
+When the device gets out of sync and the stream reaches TCP sequence
+numbers more than a max size record past the expected TCP sequence number,
+the device starts scanning for a known header pattern. For example
+for TLS 1.2 and TLS 1.3 subsequent bytes of value ``0x03 0x03`` occur
+in the SSL/TLS version field of the header. Once pattern is matched
+the device continues attempting parsing headers at expected locations
+(based on the length fields at guessed locations).
+Whenever the expected location does not contain a valid header the scan
+is restarted.
+
+When the header is matched the device sends a confirmation request
+to the kernel, asking if the guessed location is correct (if a TLS record
+really starts there), and which record sequence number the given header had.
+The kernel confirms the guessed location was correct and tells the device
+the record sequence number. Meanwhile, the device had been parsing
+and counting all records since the just-confirmed one, it adds the number
+of records it had seen to the record number provided by the kernel.
+At this point the device is in sync and can resume decryption at next
+segment boundary.
+
+In a pathological case the device may latch onto a sequence of matching
+headers and never hear back from the kernel (there is no negative
+confirmation from the kernel). The implementation may choose to periodically
+restart scan. Given how unlikely falsely-matching stream is, however,
+periodic restart is not deemed necessary.
+
+Special care has to be taken if the confirmation request is passed
+asynchronously to the packet stream and record may get processed
+by the kernel before the confirmation request.
+
+Error handling
+==============
+
+TX
+--
+
+Packets may be redirected or rerouted by the stack to a different
+device than the selected TLS offload device. The stack will handle
+such condition using the :c:func:`sk_validate_xmit_skb` helper
+(TLS offload code installs :c:func:`tls_validate_xmit_skb` at this hook).
+Offload maintains information about all records until the data is
+fully acknowledged, so if skbs reach the wrong device they can be handled
+by software fallback.
+
+Any device TLS offload handling error on the transmission side must result
+in the packet being dropped. For example if a packet got out of order
+due to a bug in the stack or the device, reached the device and can't
+be encrypted such packet must be dropped.
+
+RX
+--
+
+If the device encounters any problems with TLS offload on the receive
+side it should pass the packet to the host's networking stack as it was
+received on the wire.
+
+For example authentication failure for any record in the segment should
+result in passing the unmodified packet to the software fallback. This means
+packets should not be modified "in place". Splitting segments to handle partial
+decryption is not advised. In other words either all records in the packet
+had been handled successfully and authenticated or the packet has to be passed
+to the host's stack as it was on the wire (recovering original packet in the
+driver if device provides precise error is sufficient).
+
+The Linux networking stack does not provide a way of reporting per-packet
+decryption and authentication errors, packets with errors must simply not
+have the :c:member:`decrypted` mark set.
+
+A packet should also not be handled by the TLS offload if it contains
+incorrect checksums.
+
+Performance metrics
+===================
+
+TLS offload can be characterized by the following basic metrics:
+
+ * max connection count
+ * connection installation rate
+ * connection installation latency
+ * total cryptographic performance
+
+Note that each TCP connection requires a TLS session in both directions,
+the performance may be reported treating each direction separately.
+
+Max connection count
+--------------------
+
+The number of connections device can support can be exposed via
+``devlink resource`` API.
+
+Total cryptographic performance
+-------------------------------
+
+Offload performance may depend on segment and record size.
+
+Overload of the cryptographic subsystem of the device should not have
+significant performance impact on non-offloaded streams.
+
+Statistics
+==========
+
+Following minimum set of TLS-related statistics should be reported
+by the driver:
+
+ * ``rx_tls_decrypted`` - number of successfully decrypted TLS segments
+ * ``tx_tls_encrypted`` - number of in-order TLS segments passed to device
+ for encryption
+ * ``tx_tls_ooo`` - number of TX packets which were part of a TLS stream
+ but did not arrive in the expected order
+ * ``tx_tls_drop_no_sync_data`` - number of TX packets dropped because
+ they arrived out of order and associated record could not be found
+ (see also :ref:`pre_tls_data`)
+
+Notable corner cases, exceptions and additional requirements
+============================================================
+
+.. _5tuple_problems:
+
+5-tuple matching limitations
+----------------------------
+
+The device can only recognize received packets based on the 5-tuple
+of the socket. Current ``ktls`` implementation will not offload sockets
+routed through software interfaces such as those used for tunneling
+or virtual networking. However, many packet transformations performed
+by the networking stack (most notably any BPF logic) do not require
+any intermediate software device, therefore a 5-tuple match may
+consistently miss at the device level. In such cases the device
+should still be able to perform TX offload (encryption) and should
+fallback cleanly to software decryption (RX).
+
+Out of order
+------------
+
+Introducing extra processing in NICs should not cause packets to be
+transmitted or received out of order, for example pure ACK packets
+should not be reordered with respect to data segments.
+
+Ingress reorder
+---------------
+
+A device is permitted to perform packet reordering for consecutive
+TCP segments (i.e. placing packets in the correct order) but any form
+of additional buffering is disallowed.
+
+Coexistence with standard networking offload features
+-----------------------------------------------------
+
+Offloaded ``ktls`` sockets should support standard TCP stack features
+transparently. Enabling device TLS offload should not cause any difference
+in packets as seen on the wire.
+
+Transport layer transparency
+----------------------------
+
+The device should not modify any packet headers for the purpose
+of the simplifying TLS offload.
+
+The device should not depend on any packet headers beyond what is strictly
+necessary for TLS offload.
+
+Segment drops
+-------------
+
+Dropping packets is acceptable only in the event of catastrophic
+system errors and should never be used as an error handling mechanism
+in cases arising from normal operation. In other words, reliance
+on TCP retransmissions to handle corner cases is not acceptable.
+
+TLS device features
+-------------------
+
+Drivers should ignore the changes to TLS the device feature flags.
+These flags will be acted upon accordingly by the core ``ktls`` code.
+TLS device feature flags only control adding of new TLS connection
+offloads, old connections will remain active after flags are cleared.
+
+Known bugs
+==========
+
+skb_orphan() leaks clear text
+-----------------------------
+
+Currently drivers depend on the :c:member:`sk` member of
+:c:type:`struct sk_buff <sk_buff>` to identify segments requiring
+encryption. Any operation which removes or does not preserve the socket
+association such as :c:func:`skb_orphan` or :c:func:`skb_clone`
+will cause the driver to miss the packets and lead to clear text leaks.
+
+Redirects leak clear text
+-------------------------
+
+In the RX direction, if segment has already been decrypted by the device
+and it gets redirected or mirrored - clear text will be transmitted out.
+
+.. _pre_tls_data:
+
+Transmission of pre-TLS data
+----------------------------
+
+User can enqueue some already encrypted and framed records before enabling
+``ktls`` on the socket. Those records have to get sent as they are. This is
+perfectly easy to handle in the software case - such data will be waiting
+in the TCP layer, TLS ULP won't see it. In the offloaded case when pre-queued
+segment reaches transmission point it appears to be out of order (before the
+expected TCP sequence number) and the stack does not have a record information
+associated.
+
+All segments without record information cannot, however, be assumed to be
+pre-queued data, because a race condition exists between TCP stack queuing
+a retransmission, the driver seeing the retransmission and TCP ACK arriving
+for the retransmitted data.

-Register Set
-============
-The current architectures have the following registers.
-
-16 General propose registers, 32 bit on s/390 and 64 bit on z/Architecture,
-r0-r15 (or gpr0-gpr15), used for arithmetic and addressing.
-
-16 Control registers, 32 bit on s/390 and 64 bit on z/Architecture, cr0-cr15,
-kernel usage only, used for memory management, interrupt control, debugging
-control etc.
-
-16 Access registers (ar0-ar15), 32 bit on both s/390 and z/Architecture,
-normally not used by normal programs but potentially could be used as
-temporary storage. These registers have a 1:1 association with general
-purpose registers and are designed to be used in the so-called access
-register mode to select different address spaces.
-Access register 0 (and access register 1 on z/Architecture, which needs a
-64 bit pointer) is currently used by the pthread library as a pointer to
-the current running threads private area.
-
-16 64 bit floating point registers (fp0-fp15 ) IEEE & HFP floating
-point format compliant on G5 upwards & a Floating point control reg (FPC)
-4 64 bit registers (fp0,fp2,fp4 & fp6) HFP only on older machines.
-Note:
-Linux (currently) always uses IEEE & emulates G5 IEEE format on older machines,
-( provided the kernel is configured for this ).
-
-
-The PSW is the most important register on the machine it
-is 64 bit on s/390 & 128 bit on z/Architecture & serves the roles of
-a program counter (pc), condition code register,memory space designator.
-In IBM standard notation I am counting bit 0 as the MSB.
-It has several advantages over a normal program counter
-in that you can change address translation & program counter
-in a single instruction. To change address translation,

-have a logical=physical mapping for the address you are

-Prefix Page(s)
---------------
-This per cpu memory area is too intimately tied to the processor not to mention.
-It exists between the real addresses 0-4096 on s/390 and between 0-8192 on
-z/Architecture and is exchanged with one page on s/390 or two pages on
-z/Architecture in absolute storage by the set prefix instruction during Linux
-startup.
-This page is mapped to a different prefix for each processor in an SMP
-configuration (assuming the OS designer is sane of course).
-Bytes 0-512 (200 hex) on s/390 and 0-512, 4096-4544, 4604-5119 currently on
-z/Architecture are used by the processor itself for holding such information
-as exception indications and entry points for exceptions.
-Bytes after 0xc00 hex are used by linux for per processor globals on s/390 and
-z/Architecture (there is a gap on z/Architecture currently between 0xc00 and
-0x1000, too, which is used by Linux).
-The closest thing to this on traditional architectures is the interrupt
-vector table. This is a good thing & does simplify some of the kernel coding
-however it means that we now cannot catch stray NULL pointers in the
-kernel without hard coded checks.
-
-
-
-Address Spaces on Intel Linux
-=============================
-
-The traditional Intel Linux is approximately mapped as follows forgive
-the ascii art.
-0xFFFFFFFF 4GB Himem *****************
- * *
- * Kernel Space *
- * *
- ***************** ****************
-User Space Himem * User Stack * * *
-(typically 0xC0000000 3GB ) ***************** * *
- * Shared Libs * * Next Process *
- ***************** * to *
- * * <== * Run * <==
- * User Program * * *
- * Data BSS * * *
- * Text * * *
- * Sections * * *
-0x00000000 ***************** ****************
-
-Now it is easy to see that on Intel it is quite easy to recognise a kernel
-address as being one greater than user space himem (in this case 0xC0000000),
-and addresses of less than this are the ones in the current running program on
-this processor (if an smp box).
-If using the virtual machine ( VM ) as a debugger it is quite difficult to
-know which user process is running as the address space you are looking at
-could be from any process in the run queue.
-
-The limitation of Intels addressing technique is that the linux
-kernel uses a very simple real address to virtual addressing technique
-of Real Address=Virtual Address-User Space Himem.
-This means that on Intel the kernel linux can typically only address
-Himem=0xFFFFFFFF-0xC0000000=1GB & this is all the RAM these machines
-can typically use.
-They can lower User Himem to 2GB or lower & thus be
-able to use 2GB of RAM however this shrinks the maximum size
-of User Space from 3GB to 2GB they have a no win limit of 4GB unless
-they go to 64 Bit.
-
-
-On 390 our limitations & strengths make us slightly different.
-For backward compatibility we are only allowed use 31 bits (2GB)
-of our 32 bit addresses, however, we use entirely separate address
-spaces for the user & kernel.
-
-This means we can support 2GB of non Extended RAM on s/390, & more
-with the Extended memory management swap device &
-currently 4TB of physical memory currently on z/Architecture.
-
-
-Address Spaces on Linux for s/390 & z/Architecture
-==================================================
-
-Our addressing scheme is basically as follows:
-
- Primary Space Home Space
-Himem 0x7fffffff 2GB on s/390 ***************** ****************
-currently 0x3ffffffffff (2^42)-1 * User Stack * * *
-on z/Architecture. ***************** * *
- * Shared Libs * * *
- ***************** * *
- * * * Kernel *
- * User Program * * *
- * Data BSS * * *
- * Text * * *
- * Sections * * *
-0x00000000 ***************** ****************
-
-This also means that we need to look at the PSW problem state bit and the
-addressing mode to decide whether we are looking at user or kernel space.
-
-User space runs in primary address mode (or access register mode within
-the vdso code).
-
-The kernel usually also runs in home space mode, however when accessing
-user space the kernel switches to primary or secondary address mode if
-the mvcos instruction is not available or if a compare-and-swap (futex)
-instruction on a user space address is performed.
-
-When also looking at the ASCE control registers, this means:
-
-User space:
-- runs in primary or access register mode
-- cr1 contains the user asce
-- cr7 contains the user asce
-- cr13 contains the kernel asce
-
-Kernel space:
-- runs in home space mode
-- cr1 contains the user or kernel asce
- -> the kernel asce is loaded when a uaccess requires primary or
- secondary address mode
-- cr7 contains the user or kernel asce, (changed with set_fs())
-- cr13 contains the kernel asce
-
-In case of uaccess the kernel changes to:
-- primary space mode in case of a uaccess (copy_to_user) and uses
- e.g. the mvcp instruction to access user space. However the kernel
- will stay in home space mode if the mvcos instruction is available
-- secondary space mode in case of futex atomic operations, so that the
- instructions come from primary address space and data from secondary
- space
-
-In case of KVM, the kernel runs in home space mode, but cr1 gets switched
-to contain the gmap asce before the SIE instruction gets executed. When
-the SIE instruction is finished, cr1 will be switched back to contain the
-user asce.
-
-
-Virtual Addresses on s/390 & z/Architecture
-===========================================
-
-A virtual address on s/390 is made up of 3 parts
-The SX (segment index, roughly corresponding to the PGD & PMD in Linux
-terminology) being bits 1-11.
-The PX (page index, corresponding to the page table entry (pte) in Linux
-terminology) being bits 12-19.
-The remaining bits BX (the byte index are the offset in the page )
-i.e. bits 20 to 31.
-
-On z/Architecture in linux we currently make up an address from 4 parts.
-The region index bits (RX) 0-32 we currently use bits 22-32
-The segment index (SX) being bits 33-43
-The page index (PX) being bits 44-51
-The byte index (BX) being bits 52-63
-
-Notes:
-1) s/390 has no PMD so the PMD is really the PGD also.
-A lot of this stuff is defined in pgtable.h.
-
-2) Also seeing as s/390's page indexes are only 1k in size
-(bits 12-19 x 4 bytes per pte ) we use 1 ( page 4k )
-to make the best use of memory by updating 4 segment indices
-entries each time we mess with a PMD & use offsets
-0,1024,2048 & 3072 in this page as for our segment indexes.
-On z/Architecture our page indexes are now 2k in size
-( bits 12-19 x 8 bytes per pte ) we do a similar trick
-but only mess with 2 segment indices each time we mess with
-a PMD.
-
-3) As z/Architecture supports up to a massive 5-level page table lookup we
-can only use 3 currently on Linux ( as this is all the generic kernel
-currently supports ) however this may change in future
-this allows us to access ( according to my sums )
-4TB of virtual storage per process i.e.
-4096*512(PTES)*1024(PMDS)*2048(PGD) = 4398046511104 bytes,
-enough for another 2 or 3 of years I think :-).
-to do this we use a region-third-table designation type in
-our address space control registers.
-
-
-The Linux for s/390 & z/Architecture Kernel Task Structure
-==========================================================
-Each process/thread under Linux for S390 has its own kernel task_struct
-defined in linux/include/linux/sched.h
-The S390 on initialisation & resuming of a process on a cpu sets
-the __LC_KERNEL_STACK variable in the spare prefix area for this cpu
-(which we use for per-processor globals).
-
-The kernel stack pointer is intimately tied with the task structure for
-each processor as follows.
-
- s/390
- ************************
- * 1 page kernel stack *
- * ( 4K ) *
- ************************
- * 1 page task_struct *
- * ( 4K ) *
-8K aligned ************************
-
- z/Architecture
- ************************
- * 2 page kernel stack *
- * ( 8K ) *
- ************************
- * 2 page task_struct *
- * ( 8K ) *
-16K aligned ************************
-
-What this means is that we don't need to dedicate any register or global
-variable to point to the current running process & can retrieve it with the
-following very simple construct for s/390 & one very similar for z/Architecture.
-
-static inline struct task_struct * get_current(void)
-{
- struct task_struct *current;
- __asm__("lhi %0,-8192\n\t"
- "nr %0,15"
- : "=r" (current) );
- return current;
-}
-
-i.e. just anding the current kernel stack pointer with the mask -8192.
-Thankfully because Linux doesn't have support for nested IO interrupts
-& our devices have large buffers can survive interrupts being shut for
-short amounts of time we don't need a separate stack for interrupts.
-
-
-
-
-Register Usage & Stackframes on Linux for s/390 & z/Architecture
-=================================================================
-Overview:
----------
-This is the code that gcc produces at the top & the bottom of
-each function. It usually is fairly consistent & similar from
-function to function & if you know its layout you can probably
-make some headway in finding the ultimate cause of a problem
-after a crash without a source level debugger.
-
-Note: To follow stackframes requires a knowledge of C or Pascal &
-limited knowledge of one assembly language.
-
-It should be noted that there are some differences between the
-s/390 and z/Architecture stack layouts as the z/Architecture stack layout
-didn't have to maintain compatibility with older linkage formats.
-
-Glossary:
----------
-alloca:
-This is a built in compiler function for runtime allocation
-of extra space on the callers stack which is obviously freed
-up on function exit ( e.g. the caller may choose to allocate nothing
-of a buffer of 4k if required for temporary purposes ), it generates
-very efficient code ( a few cycles ) when compared to alternatives
-like malloc.
-
-automatics: These are local variables on the stack,
-i.e they aren't in registers & they aren't static.
-
-back-chain:
-This is a pointer to the stack pointer before entering a
-framed functions ( see frameless function ) prologue got by
-dereferencing the address of the current stack pointer,
- i.e. got by accessing the 32 bit value at the stack pointers
-current location.
-
-base-pointer:
-This is a pointer to the back of the literal pool which
-is an area just behind each procedure used to store constants
-in each function.
-
-call-clobbered: The caller probably needs to save these registers if there
-is something of value in them, on the stack or elsewhere before making a
-call to another procedure so that it can restore it later.
-
-epilogue:
-The code generated by the compiler to return to the caller.
-
-frameless-function
-A frameless function in Linux for s390 & z/Architecture is one which doesn't
-need more than the register save area (96 bytes on s/390, 160 on z/Architecture)
-given to it by the caller.
-A frameless function never:
-1) Sets up a back chain.
-2) Calls alloca.
-3) Calls other normal functions
-4) Has automatics.
-
-GOT-pointer:
-This is a pointer to the global-offset-table in ELF
-( Executable Linkable Format, Linux'es most common executable format ),
-all globals & shared library objects are found using this pointer.
-
-lazy-binding
-ELF shared libraries are typically only loaded when routines in the shared
-library are actually first called at runtime. This is lazy binding.
-
-procedure-linkage-table
-This is a table found from the GOT which contains pointers to routines
-in other shared libraries which can't be called to by easier means.
-
-prologue:
-The code generated by the compiler to set up the stack frame.
-
-outgoing-args:
-This is extra area allocated on the stack of the calling function if the
-parameters for the callee's cannot all be put in registers, the same
-area can be reused by each function the caller calls.
-
-routine-descriptor:
-A COFF executable format based concept of a procedure reference
-actually being 8 bytes or more as opposed to a simple pointer to the routine.
-This is typically defined as follows
-Routine Descriptor offset 0=Pointer to Function
-Routine Descriptor offset 4=Pointer to Table of Contents
-The table of contents/TOC is roughly equivalent to a GOT pointer.
-& it means that shared libraries etc. can be shared between several
-environments each with their own TOC.
-
-
-static-chain: This is used in nested functions a concept adopted from pascal
-by gcc not used in ansi C or C++ ( although quite useful ), basically it
-is a pointer used to reference local variables of enclosing functions.
-You might come across this stuff once or twice in your lifetime.
-
-e.g.
-The function below should return 11 though gcc may get upset & toss warnings
-about unused variables.
-int FunctionA(int a)
-{
- int b;
- FunctionC(int c)
- {
- b=c+1;
- }
- FunctionC(10);
- return(b);

-s/390 & z/Architecture Register usage
-=====================================
-r0 used by syscalls/assembly call-clobbered
-r1 used by syscalls/assembly call-clobbered
-r2 argument 0 / return value 0 call-clobbered
-r3 argument 1 / return value 1 (if long long) call-clobbered
-r4 argument 2 call-clobbered
-r5 argument 3 call-clobbered
-r6 argument 4 saved
-r7 pointer-to arguments 5 to ... saved
-r8 this & that saved
-r9 this & that saved
-r10 static-chain ( if nested function ) saved
-r11 frame-pointer ( if function used alloca ) saved
-r12 got-pointer saved
-r13 base-pointer saved
-r14 return-address saved
-r15 stack-pointer saved
-
-f0 argument 0 / return value ( float/double ) call-clobbered
-f2 argument 1 call-clobbered
-f4 z/Architecture argument 2 saved
-f6 z/Architecture argument 3 saved
-The remaining floating points
-f1,f3,f5 f7-f15 are call-clobbered.
-
-Notes:
-------
-1) The only requirement is that registers which are used
-by the callee are saved, e.g. the compiler is perfectly
-capable of using r11 for purposes other than a frame a
-frame pointer if a frame pointer is not needed.
-2) In functions with variable arguments e.g. printf the calling procedure
-is identical to one without variable arguments & the same number of
-parameters. However, the prologue of this function is somewhat more
-hairy owing to it having to move these parameters to the stack to
-get va_start, va_arg & va_end to work.
-3) Access registers are currently unused by gcc but are used in
-the kernel. Possibilities exist to use them at the moment for
-temporary storage but it isn't recommended.
-4) Only 4 of the floating point registers are used for
-parameter passing as older machines such as G3 only have only 4
-& it keeps the stack frame compatible with other compilers.
-However with IEEE floating point emulation under linux on the
-older machines you are free to use the other 12.
-5) A long long or double parameter cannot be have the
-first 4 bytes in a register & the second four bytes in the
-outgoing args area. It must be purely in the outgoing args
-area if crossing this boundary.
-6) Floating point parameters are mixed with outgoing args
-on the outgoing args area in the order the are passed in as parameters.
-7) Floating point arguments 2 & 3 are saved in the outgoing args area for
-z/Architecture

-Comments on the function test
------------------------------
-1) It didn't need to set up a pointer to the constant pool gpr13 as it is not
-used ( :-( ).
-2) This is a frameless function & no stack is bought.
-3) The compiler was clever enough to recognise that it could return the
-value in r2 as well as use it for the passed in parameter ( :-) ).
-4) The basr ( branch relative & save ) trick works as follows the instruction
-has a special case with r0,r0 with some instruction operands is understood as
-the literal value 0, some risc architectures also do this ). So now
-we are branching to the next address & the address new program counter is
-in r13,so now we subtract the size of the function prologue we have executed
-+ the size of the literal pool to get to the top of the literal pool

-Compiling programs for debugging on Linux for s/390 & z/Architecture
-====================================================================
--gdwarf-2 now works it should be considered the default debugging
-format for s/390 & z/Architecture as it is more reliable for debugging
-shared libraries, normal -g debugging works much better now
-Thanks to the IBM java compiler developers bug reports.
-
-This is typically done adding/appending the flags -g or -gdwarf-2 to the
-CFLAGS & LDFLAGS variables Makefile of the program concerned.
-
-If using gdb & you would like accurate displays of registers &
- stack traces compile without optimisation i.e make sure
-that there is no -O2 or similar on the CFLAGS line of the Makefile &
-the emitted gcc commands, obviously this will produce worse code
-( not advisable for shipment ) but it is an aid to the debugging process.
-
-This aids debugging because the compiler will copy parameters passed in
-in registers onto the stack so backtracing & looking at passed in
-parameters will work, however some larger programs which use inline functions
-will not compile without optimisation.
-
-Debugging with optimisation has since much improved after fixing
-some bugs, please make sure you are using gdb-5.0 or later developed
-after Nov'2000.
-
-
-
-Debugging under VM
-==================
-
-Notes
------
-Addresses & values in the VM debugger are always hex never decimal
-Address ranges are of the format <HexValue1>-<HexValue2> or
-<HexValue1>.<HexValue2>
-For example, the address range 0x2000 to 0x3000 can be described as 2000-3000
-or 2000.1000
-
-The VM Debugger is case insensitive.
-
-VM's strengths are usually other debuggers weaknesses you can get at any
-resource no matter how sensitive e.g. memory management resources, change
-address translation in the PSW. For kernel hacking you will reap dividends if
-you get good at it.
-
-The VM Debugger displays operators but not operands, and also the debugger
-displays useful information on the same line as the author of the code probably
-felt that it was a good idea not to go over the 80 columns on the screen.
-This isn't as unintuitive as it may seem as the s/390 instructions are easy to
-decode mentally and you can make a good guess at a lot of them as all the
-operands are nibble (half byte aligned).
-So if you have an objdump listing by hand, it is quite easy to follow, and if
-you don't have an objdump listing keep a copy of the s/390 Reference Summary
-or alternatively the s/390 principles of operation next to you.
-e.g. even I can guess that
-0001AFF8' LR 180F CC 0
-is a ( load register ) lr r0,r15
-
-Also it is very easy to tell the length of a 390 instruction from the 2 most
-significant bits in the instruction (not that this info is really useful except
-if you are trying to make sense of a hexdump of code).
-Here is a table
-Bits Instruction Length
-------------------------------------------
-00 2 Bytes
-01 4 Bytes
-10 4 Bytes
-11 6 Bytes
-
-The debugger also displays other useful info on the same line such as the
-addresses being operated on destination addresses of branches & condition codes.
-e.g.
-00019736' AHI A7DAFF0E CC 1
-000198BA' BRC A7840004 -> 000198C2' CC 0
-000198CE' STM 900EF068 >> 0FA95E78 CC 2
-
-
-
-Useful VM debugger commands
----------------------------
-
-I suppose I'd better mention this before I start
-to list the current active traces do
-Q TR
-there can be a maximum of 255 of these per set
-( more about trace sets later ).
-To stop traces issue a
-TR END.
-To delete a particular breakpoint issue
-TR DEL <breakpoint number>
-
-The PA1 key drops to CP mode so you can issue debugger commands,
-Doing alt c (on my 3270 console at least ) clears the screen.
-hitting b <enter> comes back to the running operating system
-from cp mode ( in our case linux ).
-It is typically useful to add shortcuts to your profile.exec file
-if you have one ( this is roughly equivalent to autoexec.bat in DOS ).
-file here are a few from mine.
-/* this gives me command history on issuing f12 */
-set pf12 retrieve
-/* this continues */
-set pf8 imm b
-/* goes to trace set a */
-set pf1 imm tr goto a
-/* goes to trace set b */
-set pf2 imm tr goto b
-/* goes to trace set c */
-set pf3 imm tr goto c
-
-
-
-Instruction Tracing
--------------------
-Setting a simple breakpoint
-TR I PSWA <address>
-To debug a particular function try
-TR I R <function address range>
-TR I on its own will single step.
-TR I DATA <MNEMONIC> <OPTIONAL RANGE> will trace for particular mnemonics
-e.g.
-TR I DATA 4D R 0197BC.4000
-will trace for BAS'es ( opcode 4D ) in the range 0197BC.4000
-if you were inclined you could add traces for all branch instructions &
-suffix them with the run prefix so you would have a backtrace on screen
-when a program crashes.
-TR BR <INTO OR FROM> will trace branches into or out of an address.
-e.g.
-TR BR INTO 0 is often quite useful if a program is getting awkward & deciding
-to branch to 0 & crashing as this will stop at the address before in jumps to 0.
-TR I R <address range> RUN cmd d g
-single steps a range of addresses but stays running &
-displays the gprs on each step.
-
-
-
-Displaying & modifying Registers
---------------------------------
-D G will display all the gprs
-Adding a extra G to all the commands is necessary to access the full 64 bit
-content in VM on z/Architecture. Obviously this isn't required for access
-registers as these are still 32 bit.
-e.g. DGG instead of DG
-D X will display all the control registers
-D AR will display all the access registers
-D AR4-7 will display access registers 4 to 7
-CPU ALL D G will display the GRPS of all CPUS in the configuration
-D PSW will display the current PSW
-st PSW 2000 will put the value 2000 into the PSW &
-cause crash your machine.
-D PREFIX displays the prefix offset
-
-
-Displaying Memory
------------------
-To display memory mapped using the current PSW's mapping try
-D <range>
-To make VM display a message each time it hits a particular address and
-continue try
-D I<range> will disassemble/display a range of instructions.
-ST addr 32 bit word will store a 32 bit aligned address
-D T<range> will display the EBCDIC in an address (if you are that way inclined)
-D R<range> will display real addresses ( without DAT ) but with prefixing.
-There are other complex options to display if you need to get at say home space
-but are in primary space the easiest thing to do is to temporarily
-modify the PSW to the other addressing mode, display the stuff & then
-restore it.
-
-
-
-Hints
------
-If you want to issue a debugger command without halting your virtual machine
-with the PA1 key try prefixing the command with #CP e.g.
-#cp tr i pswa 2000
-also suffixing most debugger commands with RUN will cause them not
-to stop just display the mnemonic at the current instruction on the console.
-If you have several breakpoints you want to put into your program &
-you get fed up of cross referencing with System.map
-you can do the following trick for several symbols.
-grep do_signal System.map
-which emits the following among other things
-0001f4e0 T do_signal
-now you can do
-
-TR I PSWA 0001f4e0 cmd msg * do_signal
-This sends a message to your own console each time do_signal is entered.
-( As an aside I wrote a perl script once which automatically generated a REXX
-script with breakpoints on every kernel procedure, this isn't a good idea
-because there are thousands of these routines & VM can only set 255 breakpoints
-at a time so you nearly had to spend as long pruning the file down as you would
-entering the msgs by hand), however, the trick might be useful for a single
-object file. In the 3270 terminal emulator x3270 there is a very useful option
-in the file menu called "Save Screen In File" - this is very good for keeping a
-copy of traces.
-
-From CMS help <command name> will give you online help on a particular command.
-e.g.
-HELP DISPLAY
-
-Also CP has a file called profile.exec which automatically gets called
-on startup of CMS ( like autoexec.bat ), keeping on a DOS analogy session
-CP has a feature similar to doskey, it may be useful for you to
-use profile.exec to define some keystrokes.
-e.g.
-SET PF9 IMM B
-This does a single step in VM on pressing F8.
-SET PF10 ^
-This sets up the ^ key.
-which can be used for ^c (ctrl-c),^z (ctrl-z) which can't be typed directly
-into some 3270 consoles.
-SET PF11 ^-
-This types the starting keystrokes for a sysrq see SysRq below.
-SET PF12 RETRIEVE
-This retrieves command history on pressing F12.
-
-
-Sometimes in VM the display is set up to scroll automatically this
-can be very annoying if there are messages you wish to look at
-to stop this do
-TERM MORE 255 255
-This will nearly stop automatic screen updates, however it will
-cause a denial of service if lots of messages go to the 3270 console,
-so it would be foolish to use this as the default on a production machine.
-
-
-Tracing particular processes
-----------------------------
-The kernel's text segment is intentionally at an address in memory that it will
-very seldom collide with text segments of user programs ( thanks Martin ),
-this simplifies debugging the kernel.
-However it is quite common for user processes to have addresses which collide
-this can make debugging a particular process under VM painful under normal
-circumstances as the process may change when doing a
-TR I R <address range>.
-Thankfully after reading VM's online help I figured out how to debug
-I particular process.
-
-Your first problem is to find the STD ( segment table designation )
-of the program you wish to debug.
-There are several ways you can do this here are a few
-1) objdump --syms <program to be debugged> | grep main
-To get the address of main in the program.
-tr i pswa <address of main>
-Start the program, if VM drops to CP on what looks like the entry
-point of the main function this is most likely the process you wish to debug.
-Now do a D X13 or D XG13 on z/Architecture.
-On 31 bit the STD is bits 1-19 ( the STO segment table origin )
-& 25-31 ( the STL segment table length ) of CR13.
-now type
-TR I R STD <CR13's value> 0.7fffffff
-e.g.
-TR I R STD 8F32E1FF 0.7fffffff
-Another very useful variation is
-TR STORE INTO STD <CR13's value> <address range>
-for finding out when a particular variable changes.
-
-An alternative way of finding the STD of a currently running process
-is to do the following, ( this method is more complex but
-could be quite convenient if you aren't updating the kernel much &
-so your kernel structures will stay constant for a reasonable period of
-time ).
-
-grep task /proc/<pid>/status
-from this you should see something like
-task: 0f160000 ksp: 0f161de8 pt_regs: 0f161f68
-This now gives you a pointer to the task structure.
-Now make CC:="s390-gcc -g" kernel/sched.s
-To get the task_struct stabinfo.
-( task_struct is defined in include/linux/sched.h ).
-Now we want to look at
-task->active_mm->pgd
-on my machine the active_mm in the task structure stab is
-active_mm:(4,12),672,32
-its offset is 672/8=84=0x54
-the pgd member in the mm_struct stab is
-pgd:(4,6)=*(29,5),96,32
-so its offset is 96/8=12=0xc
-
-so we'll
-hexdump -s 0xf160054 /dev/mem | more
-i.e. task_struct+active_mm offset
-to look at the active_mm member
-f160054 0fee cc60 0019 e334 0000 0000 0000 0011
-hexdump -s 0x0feecc6c /dev/mem | more
-i.e. active_mm+pgd offset
-feecc6c 0f2c 0000 0000 0001 0000 0001 0000 0010
-we get something like
-now do
-TR I R STD <pgd|0x7f> 0.7fffffff
-i.e. the 0x7f is added because the pgd only
-gives the page table origin & we need to set the low bits
-to the maximum possible segment table length.
-TR I R STD 0f2c007f 0.7fffffff
-on z/Architecture you'll probably need to do
-TR I R STD <pgd|0x7> 0.ffffffffffffffff
-to set the TableType to 0x1 & the Table length to 3.
-
-
-
-Tracing Program Exceptions
---------------------------
-If you get a crash which says something like
-illegal operation or specification exception followed by a register dump
-You can restart linux & trace these using the tr prog <range or value> trace
-option.
-
-
-The most common ones you will normally be tracing for is
-1=operation exception
-2=privileged operation exception
-4=protection exception
-5=addressing exception
-6=specification exception
-10=segment translation exception
-11=page translation exception
-
-The full list of these is on page 22 of the current s/390 Reference Summary.
-e.g.
-tr prog 10 will trace segment translation exceptions.
-tr prog on its own will trace all program interruption codes.
-
-Trace Sets
-----------
-On starting VM you are initially in the INITIAL trace set.
-You can do a Q TR to verify this.
-If you have a complex tracing situation where you wish to wait for instance
-till a driver is open before you start tracing IO, but know in your
-heart that you are going to have to make several runs through the code till you
-have a clue whats going on.
-
-What you can do is
-TR I PSWA <Driver open address>
-hit b to continue till breakpoint
-reach the breakpoint
-now do your
-TR GOTO B
-TR IO 7c08-7c09 inst int run
-or whatever the IO channels you wish to trace are & hit b
-
-To got back to the initial trace set do
-TR GOTO INITIAL
-& the TR I PSWA <Driver open address> will be the only active breakpoint again.
-
-
-Tracing linux syscalls under VM
--------------------------------
-Syscalls are implemented on Linux for S390 by the Supervisor call instruction
-(SVC). There 256 possibilities of these as the instruction is made up of a 0xA
-opcode and the second byte being the syscall number. They are traced using the
-simple command:
-TR SVC <Optional value or range>
-the syscalls are defined in linux/arch/s390/include/asm/unistd.h
-e.g. to trace all file opens just do
-TR SVC 5 ( as this is the syscall number of open )
-
-
-SMP Specific commands
----------------------
-To find out how many cpus you have
-Q CPUS displays all the CPU's available to your virtual machine
-To find the cpu that the current cpu VM debugger commands are being directed at
-do Q CPU to change the current cpu VM debugger commands are being directed at do
-CPU <desired cpu no>
-
-On a SMP guest issue a command to all CPUs try prefixing the command with cpu
-all. To issue a command to a particular cpu try cpu <cpu number> e.g.
-CPU 01 TR I R 2000.3000
-If you are running on a guest with several cpus & you have a IO related problem
-& cannot follow the flow of code but you know it isn't smp related.
-from the bash prompt issue
-shutdown -h now or halt.
-do a Q CPUS to find out how many cpus you have
-detach each one of them from cp except cpu 0
-by issuing a
-DETACH CPU 01-(number of cpus in configuration)
-& boot linux again.
-TR SIGP will trace inter processor signal processor instructions.
-DEFINE CPU 01-(number in configuration)
-will get your guests cpus back.
-
-
-Help for displaying ascii textstrings
--------------------------------------
-On the very latest VM Nucleus'es VM can now display ascii
-( thanks Neale for the hint ) by doing
-D TX<lowaddr>.<len>
-e.g.
-D TX0.100
-
-Alternatively
-=============
-Under older VM debuggers (I love EBDIC too) you can use following little
-program which converts a command line of hex digits to ascii text. It can be
-compiled under linux and you can copy the hex digits from your x3270 terminal
-to your xterm if you are debugging from a linuxbox.
-
-This is quite useful when looking at a parameter passed in as a text string
-under VM ( unless you are good at decoding ASCII in your head ).
-
-e.g. consider tracing an open syscall
-TR SVC 5
-We have stopped at a breakpoint
-000151B0' SVC 0A05 -> 0001909A' CC 0
-
-D 20.8 to check the SVC old psw in the prefix area and see was it from userspace
-(for the layout of the prefix area consult the "Fixed Storage Locations"
-chapter of the s/390 Reference Summary if you have it available).
-V00000020 070C2000 800151B2
-The problem state bit wasn't set & it's also too early in the boot sequence
-for it to be a userspace SVC if it was we would have to temporarily switch the
-psw to user space addressing so we could get at the first parameter of the open
-in gpr2.
-Next do a
-D G2
-GPR 2 = 00014CB4
-Now display what gpr2 is pointing to
-D 00014CB4.20
-V00014CB4 2F646576 2F636F6E 736F6C65 00001BF5
-V00014CC4 FC00014C B4001001 E0001000 B8070707
-Now copy the text till the first 00 hex ( which is the end of the string
-to an xterm & do hex2ascii on it.
-hex2ascii 2F646576 2F636F6E 736F6C65 00
-outputs
-Decoded Hex:=/ d e v / c o n s o l e 0x00
-We were opening the console device,
-
-You can compile the code below yourself for practice :-),

-Stack tracing under VM
-----------------------
-A basic backtrace
------------------
-
-Here are the tricks I use 9 out of 10 times it works pretty well,
-
-When your backchain reaches a dead end
---------------------------------------
-This can happen when an exception happens in the kernel and the kernel is
-entered twice. If you reach the NULL pointer at the end of the back chain you
-should be able to sniff further back if you follow the following tricks.
-1) A kernel address should be easy to recognise since it is in
-primary space & the problem state bit isn't set & also
-The Hi bit of the address is set.
-2) Another backchain should also be easy to recognise since it is an
-address pointing to another address approximately 100 bytes or 0x70 hex
-behind the current stackpointer.
-
-
-Here is some practice.
-boot the kernel & hit PA1 at some random time
-d g to display the gprs, this should display something like
-GPR 0 = 00000001 00156018 0014359C 00000000
-GPR 4 = 00000001 001B8888 000003E0 00000000
-GPR 8 = 00100080 00100084 00000000 000FE000
-GPR 12 = 00010400 8001B2DC 8001B36A 000FFED8
-Note that GPR14 is a return address but as we are real men we are going to
-trace the stack.
-display 0x40 bytes after the stack pointer.
-
-V000FFED8 000FFF38 8001B838 80014C8E 000FFF38
-V000FFEE8 00000000 00000000 000003E0 00000000
-V000FFEF8 00100080 00100084 00000000 000FE000
-V000FFF08 00010400 8001B2DC 8001B36A 000FFED8
-
-
-Ah now look at whats in sp+56 (sp+0x38) this is 8001B36A our saved r14 if
-you look above at our stackframe & also agrees with GPR14.
-
-now backchain
-d 000FFF38.40
-we now are taking the contents of SP to get our first backchain.
-
-V000FFF38 000FFFA0 00000000 00014995 00147094
-V000FFF48 00147090 001470A0 000003E0 00000000
-V000FFF58 00100080 00100084 00000000 001BF1D0
-V000FFF68 00010400 800149BA 80014CA6 000FFF38
-
-This displays a 2nd return address of 80014CA6
-
-now do d 000FFFA0.40 for our 3rd backchain
-
-V000FFFA0 04B52002 0001107F 00000000 00000000
-V000FFFB0 00000000 00000000 FF000000 0001107F
-V000FFFC0 00000000 00000000 00000000 00000000
-V000FFFD0 00010400 80010802 8001085A 000FFFA0
-
-
-our 3rd return address is 8001085A
-
-as the 04B52002 looks suspiciously like rubbish it is fair to assume that the
-kernel entry routines for the sake of optimisation don't set up a backchain.
-
-now look at System.map to see if the addresses make any sense.
-
-grep -i 0001b3 System.map
-outputs among other things
-0001b304 T cpu_idle
-so 8001B36A
-is cpu_idle+0x66 ( quiet the cpu is asleep, don't wake it )
-
-
-grep -i 00014 System.map
-produces among other things
-00014a78 T start_kernel
-so 0014CA6 is start_kernel+some hex number I can't add in my head.
-
-grep -i 00108 System.map
-this produces
-00010800 T _stext
-so 8001085A is _stext+0x5a
-
-Congrats you've done your first backchain.

-s/390 & z/Architecture IO Overview
-==================================
-
-I am not going to give a course in 390 IO architecture as this would take me
-quite a while and I'm no expert. Instead I'll give a 390 IO architecture
-summary for Dummies. If you have the s/390 principles of operation available
-read this instead. If nothing else you may find a few useful keywords in here
-and be able to use them on a web search engine to find more useful information.
-
-Unlike other bus architectures modern 390 systems do their IO using mostly
-fibre optics and devices such as tapes and disks can be shared between several
-mainframes. Also S390 can support up to 65536 devices while a high end PC based
-system might be choking with around 64.
-
-Here is some of the common IO terminology:
-
-Subchannel:
-This is the logical number most IO commands use to talk to an IO device. There
-can be up to 0x10000 (65536) of these in a configuration, typically there are a
-few hundred. Under VM for simplicity they are allocated contiguously, however
-on the native hardware they are not. They typically stay consistent between
-boots provided no new hardware is inserted or removed.
-Under Linux for s390 we use these as IRQ's and also when issuing an IO command
-(CLEAR SUBCHANNEL, HALT SUBCHANNEL, MODIFY SUBCHANNEL, RESUME SUBCHANNEL,
-START SUBCHANNEL, STORE SUBCHANNEL and TEST SUBCHANNEL). We use this as the ID
-of the device we wish to talk to. The most important of these instructions are
-START SUBCHANNEL (to start IO), TEST SUBCHANNEL (to check whether the IO
-completed successfully) and HALT SUBCHANNEL (to kill IO). A subchannel can have
-up to 8 channel paths to a device, this offers redundancy if one is not
-available.
-
-Device Number:
-This number remains static and is closely tied to the hardware. There are 65536
-of these, made up of a CHPID (Channel Path ID, the most significant 8 bits) and
-another lsb 8 bits. These remain static even if more devices are inserted or
-removed from the hardware. There is a 1 to 1 mapping between subchannels and
-device numbers, provided devices aren't inserted or removed.
-
-Channel Control Words:
-CCWs are linked lists of instructions initially pointed to by an operation
-request block (ORB), which is initially given to Start Subchannel (SSCH)
-command along with the subchannel number for the IO subsystem to process
-while the CPU continues executing normal code.
-CCWs come in two flavours, Format 0 (24 bit for backward compatibility) and
-Format 1 (31 bit). These are typically used to issue read and write (and many
-other) instructions. They consist of a length field and an absolute address
-field.
-Each IO typically gets 1 or 2 interrupts, one for channel end (primary status)
-when the channel is idle, and the second for device end (secondary status).
-Sometimes you get both concurrently. You check how the IO went on by issuing a
-TEST SUBCHANNEL at each interrupt, from which you receive an Interruption
-response block (IRB). If you get channel and device end status in the IRB
-without channel checks etc. your IO probably went okay. If you didn't you
-probably need to examine the IRB, extended status word etc.
-If an error occurs, more sophisticated control units have a facility known as
-concurrent sense. This means that if an error occurs Extended sense information
-will be presented in the Extended status word in the IRB. If not you have to
-issue a subsequent SENSE CCW command after the test subchannel.
-
-
-TPI (Test pending interrupt) can also be used for polled IO, but in
-multitasking multiprocessor systems it isn't recommended except for
-checking special cases (i.e. non looping checks for pending IO etc.).
-
-Store Subchannel and Modify Subchannel can be used to examine and modify
-operating characteristics of a subchannel (e.g. channel paths).
-
-Other IO related Terms:
-Sysplex: S390's Clustering Technology
-QDIO: S390's new high speed IO architecture to support devices such as gigabit
-ethernet, this architecture is also designed to be forward compatible with
-upcoming 64 bit machines.
-
-
-General Concepts
-
-Input Output Processors (IOP's) are responsible for communicating between
-the mainframe CPU's & the channel & relieve the mainframe CPU's from the
-burden of communicating with IO devices directly, this allows the CPU's to
-concentrate on data processing.
-
-IOP's can use one or more links ( known as channel paths ) to talk to each
-IO device. It first checks for path availability & chooses an available one,
-then starts ( & sometimes terminates IO ).
-There are two types of channel path: ESCON & the Parallel IO interface.
-
-IO devices are attached to control units, control units provide the
-logic to interface the channel paths & channel path IO protocols to
-the IO devices, they can be integrated with the devices or housed separately
-& often talk to several similar devices ( typical examples would be raid
-controllers or a control unit which connects to 1000 3270 terminals ).

-
-The 390 IO systems come in 2 flavours the current 390 machines support both
-
-The Older 360 & 370 Interface,sometimes called the Parallel I/O interface,
-sometimes called Bus-and Tag & sometimes Original Equipment Manufacturers
-Interface (OEMI).
-
-This byte wide Parallel channel path/bus has parity & data on the "Bus" cable
-and control lines on the "Tag" cable. These can operate in byte multiplex mode
-for sharing between several slow devices or burst mode and monopolize the
-channel for the whole burst. Up to 256 devices can be addressed on one of these
-cables. These cables are about one inch in diameter. The maximum unextended
-length supported by these cables is 125 Meters but this can be extended up to
-2km with a fibre optic channel extended such as a 3044. The maximum burst speed
-supported is 4.5 megabytes per second. However, some really old processors
-support only transfer rates of 3.0, 2.0 & 1.0 MB/sec.
-One of these paths can be daisy chained to up to 8 control units.
-
-
-ESCON if fibre optic it is also called FICON
-Was introduced by IBM in 1990. Has 2 fibre optic cables and uses either leds or
-lasers for communication at a signaling rate of up to 200 megabits/sec. As
-10bits are transferred for every 8 bits info this drops to 160 megabits/sec
-and to 18.6 Megabytes/sec once control info and CRC are added. ESCON only
-operates in burst mode.
-
-ESCONs typical max cable length is 3km for the led version and 20km for the
-laser version known as XDF (extended distance facility). This can be further
-extended by using an ESCON director which triples the above mentioned ranges.
-Unlike Bus & Tag as ESCON is serial it uses a packet switching architecture,
-the standard Bus & Tag control protocol is however present within the packets.
-Up to 256 devices can be attached to each control unit that uses one of these
-interfaces.
-
-Common 390 Devices include:
-Network adapters typically OSA2,3172's,2116's & OSA-E gigabit ethernet adapters,
-Consoles 3270 & 3215 (a teletype emulated under linux for a line mode console).
-DASD's direct access storage devices ( otherwise known as hard disks ).
-Tape Drives.
-CTC ( Channel to Channel Adapters ),
-ESCON or Parallel Cables used as a very high speed serial link
-between 2 machines.
-
-
-Debugging IO on s/390 & z/Architecture under VM
-===============================================
-
-Now we are ready to go on with IO tracing commands under VM
-
-A few self explanatory queries:
-Q OSA
-Q CTC
-Q DISK ( This command is CMS specific )
-Q DASD
-
-
-
-
-
-
-Q OSA on my machine returns
-OSA 7C08 ON OSA 7C08 SUBCHANNEL = 0000
-OSA 7C09 ON OSA 7C09 SUBCHANNEL = 0001
-OSA 7C14 ON OSA 7C14 SUBCHANNEL = 0002
-OSA 7C15 ON OSA 7C15 SUBCHANNEL = 0003
-
-If you have a guest with certain privileges you may be able to see devices
-which don't belong to you. To avoid this, add the option V.
-e.g.
-Q V OSA
-
-Now using the device numbers returned by this command we will
-Trace the io starting up on the first device 7c08 & 7c09
-In our simplest case we can trace the
-start subchannels
-like TR SSCH 7C08-7C09
-or the halt subchannels
-or TR HSCH 7C08-7C09
-MSCH's ,STSCH's I think you can guess the rest
-
-A good trick is tracing all the IO's and CCWS and spooling them into the reader
-of another VM guest so he can ftp the logfile back to his own machine. I'll do
-a small bit of this and give you a look at the output.
-
-1) Spool stdout to VM reader
-SP PRT TO (another vm guest ) or * for the local vm guest
-2) Fill the reader with the trace
-TR IO 7c08-7c09 INST INT CCW PRT RUN
-3) Start up linux
-i 00c
-4) Finish the trace
-TR END
-5) close the reader
-C PRT
-6) list reader contents
-RDRLIST
-7) copy it to linux4's minidisk
-RECEIVE / LOG TXT A1 ( replace
-8)
-filel & press F11 to look at it
-You should see something like:
-
-00020942' SSCH B2334000 0048813C CC 0 SCH 0000 DEV 7C08
- CPA 000FFDF0 PARM 00E2C9C4 KEY 0 FPI C0 LPM 80
- CCW 000FFDF0 E4200100 00487FE8 0000 E4240100 ........
- IDAL 43D8AFE8
- IDAL 0FB76000
-00020B0A' I/O DEV 7C08 -> 000197BC' SCH 0000 PARM 00E2C9C4
-00021628' TSCH B2354000 >> 00488164 CC 0 SCH 0000 DEV 7C08
- CCWA 000FFDF8 DEV STS 0C SCH STS 00 CNT 00EC
- KEY 0 FPI C0 CC 0 CTLS 4007
-00022238' STSCH B2344000 >> 00488108 CC 0 SCH 0000 DEV 7C08
-
-If you don't like messing up your readed ( because you possibly booted from it )
-you can alternatively spool it to another readers guest.
-
-
-Other common VM device related commands
----------------------------------------------
-These commands are listed only because they have
-been of use to me in the past & may be of use to
-you too. For more complete info on each of the commands
-use type HELP <command> from CMS.
-detaching devices
-DET <devno range>
-ATT <devno range> <guest>
-attach a device to guest * for your own guest
-READY <devno> cause VM to issue a fake interrupt.
-
-The VARY command is normally only available to VM administrators.
-VARY ON PATH <path> TO <devno range>
-VARY OFF PATH <PATH> FROM <devno range>
-This is used to switch on or off channel paths to devices.
-
-Q CHPID <channel path ID>
-This displays state of devices using this channel path
-D SCHIB <subchannel>
-This displays the subchannel information SCHIB block for the device.
-this I believe is also only available to administrators.
-DEFINE CTC <devno>
-defines a virtual CTC channel to channel connection
-2 need to be defined on each guest for the CTC driver to use.
-COUPLE devno userid remote devno
-Joins a local virtual device to a remote virtual device
-( commonly used for the CTC driver ).
-
-Building a VM ramdisk under CMS which linux can use
-def vfb-<blocksize> <subchannel> <number blocks>
-blocksize is commonly 4096 for linux.
-Formatting it
-format <subchannel> <driver letter e.g. x> (blksize <blocksize>
-
-Sharing a disk between multiple guests
-LINK userid devno1 devno2 mode password
-
-
-
-GDB on S390
-===========
-N.B. if compiling for debugging gdb works better without optimisation
-( see Compiling programs for debugging )
-
-invocation
-----------
-gdb <victim program> <optional corefile>
-
-Online help
------------
-help: gives help on commands
-e.g.
-help
-help display
-Note gdb's online help is very good use it.
-
-
-Assembly
---------
-info registers: displays registers other than floating point.
-info all-registers: displays floating points as well.
-disassemble: disassembles
-e.g.
-disassemble without parameters will disassemble the current function
-disassemble $pc $pc+10
-
-Viewing & modifying variables
------------------------------
-print or p: displays variable or register
-e.g. p/x $sp will display the stack pointer
-
-display: prints variable or register each time program stops
-e.g.
-display/x $pc will display the program counter
-display argc
-
-undisplay : undo's display's
-
-info breakpoints: shows all current breakpoints
-
-info stack: shows stack back trace (if this doesn't work too well, I'll show
-you the stacktrace by hand below).
-
-info locals: displays local variables.
-
-info args: display current procedure arguments.
-
-set args: will set argc & argv each time the victim program is invoked.
-
-set <variable>=value
-set argc=100
-set $pc=0
-
-
-
-Modifying execution
--------------------
-step: steps n lines of sourcecode
-step steps 1 line.
-step 100 steps 100 lines of code.
-
-next: like step except this will not step into subroutines
-
-stepi: steps a single machine code instruction.
-e.g. stepi 100
-
-nexti: steps a single machine code instruction but will not step into
-subroutines.
-
-finish: will run until exit of the current routine
-
-run: (re)starts a program
-
-cont: continues a program
-
-quit: exits gdb.
-
-
-breakpoints
-------------
-
-break
-sets a breakpoint
-e.g.
-
-break main
-
-break *$pc
-
-break *0x400618
-
-Here's a really useful one for large programs
-rbr
-Set a breakpoint for all functions matching REGEXP
-e.g.
-rbr 390
-will set a breakpoint with all functions with 390 in their name.
-
-info breakpoints
-lists all breakpoints
-
-delete: delete breakpoint by number or delete them all
-e.g.
-delete 1 will delete the first breakpoint
-delete will delete them all
-
-watch: This will set a watchpoint ( usually hardware assisted ),
-This will watch a variable till it changes
-e.g.
-watch cnt, will watch the variable cnt till it changes.
-As an aside unfortunately gdb's, architecture independent watchpoint code
-is inconsistent & not very good, watchpoints usually work but not always.
-
-info watchpoints: Display currently active watchpoints
-
-condition: ( another useful one )
-Specify breakpoint number N to break only if COND is true.
-Usage is `condition N COND', where N is an integer and COND is an
-expression to be evaluated whenever breakpoint N is reached.
-
-
-
-User defined functions/macros
------------------------------
-define: ( Note this is very very useful,simple & powerful )
-usage define <name> <list of commands> end
-
-examples which you should consider putting into .gdbinit in your home directory
-define d
-stepi
-disassemble $pc $pc+10
-end
-
-define e
-nexti
-disassemble $pc $pc+10
-end
-
-
-Other hard to classify stuff
-----------------------------
-signal n:
-sends the victim program a signal.
-e.g. signal 3 will send a SIGQUIT.
-
-info signals:
-what gdb does when the victim receives certain signals.
-
-list:
-e.g.
-list lists current function source
-list 1,10 list first 10 lines of current file.
-list test.c:1,10
-
-
-directory:
-Adds directories to be searched for source if gdb cannot find the source.
-(note it is a bit sensitive about slashes)
-e.g. To add the root of the filesystem to the searchpath do
-directory //
-
-
-call <function>
-This calls a function in the victim program, this is pretty powerful
-e.g.
-(gdb) call printf("hello world")
-outputs:
-$1 = 11
-
-You might now be thinking that the line above didn't work, something extra had
-to be done.
-(gdb) call fflush(stdout)
-hello world$2 = 0
-As an aside the debugger also calls malloc & free under the hood
-to make space for the "hello world" string.
-
-
-
-hints
------
-1) command completion works just like bash
-( if you are a bad typist like me this really helps )
-e.g. hit br <TAB> & cursor up & down :-).
-
-2) if you have a debugging problem that takes a few steps to recreate
-put the steps into a file called .gdbinit in your current working directory
-if you have defined a few extra useful user defined commands put these in
-your home directory & they will be read each time gdb is launched.
-
-A typical .gdbinit file might be.
-break main
-run
-break runtime_exception
-cont
-
-
-stack chaining in gdb by hand
------------------------------
-This is done using a the same trick described for VM
-p/x (*($sp+56))&0x7fffffff get the first backchain.
-
-For z/Architecture
-Replace 56 with 112 & ignore the &0x7fffffff
-in the macros below & do nasty casts to longs like the following
-as gdb unfortunately deals with printed arguments as ints which
-messes up everything.
-i.e. here is a 3rd backchain dereference
-p/x *(long *)(***(long ***)$sp+112)
-
-
-this outputs
-$5 = 0x528f18
-on my machine.
-Now you can use
-info symbol (*($sp+56))&0x7fffffff
-you might see something like.
-rl_getc + 36 in section .text telling you what is located at address 0x528f18
-Now do.
-p/x (*(*$sp+56))&0x7fffffff
-This outputs
-$6 = 0x528ed0
-Now do.
-info symbol (*(*$sp+56))&0x7fffffff
-rl_read_key + 180 in section .text
-now do
-p/x (*(**$sp+56))&0x7fffffff
-& so on.
-
-Disassembling instructions without debug info
----------------------------------------------
-gdb typically complains if there is a lack of debugging
-symbols in the disassemble command with
-"No function contains specified address." To get around
-this do
-x/<number lines to disassemble>xi <address>
-e.g.
-x/20xi 0x400730
-
-
-
-Note: Remember gdb has history just like bash you don't need to retype the
-whole line just use the up & down arrows.
-
-
-
-For more info
--------------
-From your linuxbox do
-man gdb or info gdb.
-
-core dumps
-----------
-What a core dump ?,
-A core dump is a file generated by the kernel (if allowed) which contains the
-registers and all active pages of the program which has crashed.
-From this file gdb will allow you to look at the registers, stack trace and
-memory of the program as if it just crashed on your system. It is usually
-called core and created in the current working directory.
-This is very useful in that a customer can mail a core dump to a technical
-support department and the technical support department can reconstruct what
-happened. Provided they have an identical copy of this program with debugging
-symbols compiled in and the source base of this build is available.
-In short it is far more useful than something like a crash log could ever hope
-to be.
-
-Why have I never seen one ?.
-Probably because you haven't used the command
-ulimit -c unlimited in bash
-to allow core dumps, now do
-ulimit -a
-to verify that the limit was accepted.
-
-A sample core dump
-To create this I'm going to do
-ulimit -c unlimited
-gdb
-to launch gdb (my victim app. ) now be bad & do the following from another
-telnet/xterm session to the same machine
-ps -aux | grep gdb
-kill -SIGSEGV <gdb's pid>
-or alternatively use killall -SIGSEGV gdb if you have the killall command.
-Now look at the core dump.
-./gdb core
-Displays the following

-LDD
-===
-This is a program which lists the shared libraries which a library needs,
-Note you also get the relocations of the shared library text segments which
-help when using objdump --source.
-e.g.
- ldd ./gdb
-outputs
-libncurses.so.4 => /usr/lib/libncurses.so.4 (0x40018000)
-libm.so.6 => /lib/libm.so.6 (0x4005e000)
-libc.so.6 => /lib/libc.so.6 (0x40084000)
-/lib/ld-linux.so.2 => /lib/ld-linux.so.2 (0x40000000)
-
-
-Debugging shared libraries
-==========================
-Most programs use shared libraries, however it can be very painful
-when you single step instruction into a function like printf for the
-first time & you end up in functions like _dl_runtime_resolve this is
-the ld.so doing lazy binding, lazy binding is a concept in ELF where
-shared library functions are not loaded into memory unless they are
-actually used, great for saving memory but a pain to debug.
-To get around this either relink the program -static or exit gdb type
-export LD_BIND_NOW=true this will stop lazy binding & restart the gdb'ing
-the program in question.
-
-
-
-Debugging modules
-=================
-As modules are dynamically loaded into the kernel their address can be
-anywhere to get around this use the -m option with insmod to emit a load
-map which can be piped into a file if required.
-
-The proc file system
-====================
-What is it ?.
-It is a filesystem created by the kernel with files which are created on demand
-by the kernel if read, or can be used to modify kernel parameters,
-it is a powerful concept.
-
-e.g.
-
-cat /proc/sys/net/ipv4/ip_forward
-On my machine outputs
-0
-telling me ip_forwarding is not on to switch it on I can do
-echo 1 > /proc/sys/net/ipv4/ip_forward
-cat it again
-cat /proc/sys/net/ipv4/ip_forward
-On my machine now outputs
-1
-IP forwarding is on.
-There is a lot of useful info in here best found by going in and having a look
-around, so I'll take you through some entries I consider important.
-
-All the processes running on the machine have their own entry defined by
-/proc/<pid>
-So lets have a look at the init process
-cd /proc/1
-
-cat cmdline
-emits
-init [2]
-
-cd /proc/1/fd
-This contains numerical entries of all the open files,
-some of these you can cat e.g. stdout (2)
-
-cat /proc/29/maps
-on my machine emits
-

-Showing us the shared libraries init uses where they are in memory
-& memory access permissions for each virtual memory area.

-Some driver debugging techniques
-================================
-debug feature
--------------
-Some of our drivers now support a "debug feature" in
-/proc/s390dbf see s390dbf.txt in the linux/Documentation directory
-for more info.
-e.g.
-to switch on the lcs "debug feature"
-echo 5 > /proc/s390dbf/lcs/level
-& then after the error occurred.
-cat /proc/s390dbf/lcs/sprintf >/logfile
-the logfile now contains some information which may help
-tech support resolve a problem in the field.
-
-
-
-high level debugging network drivers
-------------------------------------
-ifconfig is a quite useful command
-it gives the current state of network drivers.
-
-If you suspect your network device driver is dead
-one way to check is type
-ifconfig <network device>
-e.g. tr0
-You should see something like
-tr0 Link encap:16/4 Mbps Token Ring (New) HWaddr 00:04:AC:20:8E:48
- inet addr:9.164.185.132 Bcast:9.164.191.255 Mask:255.255.224.0
- UP BROADCAST RUNNING MULTICAST MTU:2000 Metric:1
- RX packets:246134 errors:0 dropped:0 overruns:0 frame:0
- TX packets:5 errors:0 dropped:0 overruns:0 carrier:0
- collisions:0 txqueuelen:100
-
-if the device doesn't say up
-try
-/etc/rc.d/init.d/network start
-( this starts the network stack & hopefully calls ifconfig tr0 up ).
-ifconfig looks at the output of /proc/net/dev and presents it in a more
-presentable form.
-Now ping the device from a machine in the same subnet.
-if the RX packets count & TX packets counts don't increment you probably
-have problems.
-next
-cat /proc/net/arp
-Do you see any hardware addresses in the cache if not you may have problems.
-Next try
-ping -c 5 <broadcast_addr> i.e. the Bcast field above in the output of
-ifconfig. Do you see any replies from machines other than the local machine
-if not you may have problems. also if the TX packets count in ifconfig
-hasn't incremented either you have serious problems in your driver
-(e.g. the txbusy field of the network device being stuck on )
-or you may have multiple network devices connected.
-
-
-chandev
--------
-There is a new device layer for channel devices, some
-drivers e.g. lcs are registered with this layer.
-If the device uses the channel device layer you'll be
-able to find what interrupts it uses & the current state
-of the device.
-See the manpage chandev.8 &type cat /proc/chandev for more info.
-
-
-SysRq
-=====
-This is now supported by linux for s/390 & z/Architecture.
-To enable it do compile the kernel with
-Kernel Hacking -> Magic SysRq Key Enabled
-echo "1" > /proc/sys/kernel/sysrq
-also type
-echo "8" >/proc/sys/kernel/printk
-To make printk output go to console.
-On 390 all commands are prefixed with
-^-
-e.g.
-^-t will show tasks.
-^-? or some unknown command will display help.
-The sysrq key reading is very picky ( I have to type the keys in an
- xterm session & paste them into the x3270 console )
-& it may be wise to predefine the keys as described in the VM hints above
-
-This is particularly useful for syncing disks unmounting & rebooting
-if the machine gets partially hung.

+Register Set
+============
+The current architectures have the following registers.
+
+16 General propose registers, 32 bit on s/390 and 64 bit on z/Architecture,
+r0-r15 (or gpr0-gpr15), used for arithmetic and addressing.
+
+16 Control registers, 32 bit on s/390 and 64 bit on z/Architecture, cr0-cr15,
+kernel usage only, used for memory management, interrupt control, debugging
+control etc.
+
+16 Access registers (ar0-ar15), 32 bit on both s/390 and z/Architecture,
+normally not used by normal programs but potentially could be used as
+temporary storage. These registers have a 1:1 association with general
+purpose registers and are designed to be used in the so-called access
+register mode to select different address spaces.
+Access register 0 (and access register 1 on z/Architecture, which needs a
+64 bit pointer) is currently used by the pthread library as a pointer to
+the current running threads private area.
+
+16 64-bit floating point registers (fp0-fp15 ) IEEE & HFP floating
+point format compliant on G5 upwards & a Floating point control reg (FPC)
+
+4 64-bit registers (fp0,fp2,fp4 & fp6) HFP only on older machines.
+
+Note:
+ Linux (currently) always uses IEEE & emulates G5 IEEE format on older
+ machines, ( provided the kernel is configured for this ).
+
+
+The PSW is the most important register on the machine it
+is 64 bit on s/390 & 128 bit on z/Architecture & serves the roles of
+a program counter (pc), condition code register,memory space designator.
+In IBM standard notation I am counting bit 0 as the MSB.
+It has several advantages over a normal program counter
+in that you can change address translation & program counter
+in a single instruction. To change address translation,
+e.g. switching address translation off requires that you
+have a logical=physical mapping for the address you are
+currently running at.

+Prefix Page(s)
+--------------
+This per cpu memory area is too intimately tied to the processor not to mention.
+It exists between the real addresses 0-4096 on s/390 and between 0-8192 on
+z/Architecture and is exchanged with one page on s/390 or two pages on
+z/Architecture in absolute storage by the set prefix instruction during Linux
+startup.
+
+This page is mapped to a different prefix for each processor in an SMP
+configuration (assuming the OS designer is sane of course).
+
+Bytes 0-512 (200 hex) on s/390 and 0-512, 4096-4544, 4604-5119 currently on
+z/Architecture are used by the processor itself for holding such information
+as exception indications and entry points for exceptions.
+
+Bytes after 0xc00 hex are used by linux for per processor globals on s/390 and
+z/Architecture (there is a gap on z/Architecture currently between 0xc00 and
+0x1000, too, which is used by Linux).
+
+The closest thing to this on traditional architectures is the interrupt
+vector table. This is a good thing & does simplify some of the kernel coding
+however it means that we now cannot catch stray NULL pointers in the
+kernel without hard coded checks.
+
+
+
+Address Spaces on Intel Linux
+=============================
+
+The traditional Intel Linux is approximately mapped as follows forgive
+the ascii art::
+
+ 0xFFFFFFFF 4GB Himem *****************
+ * *
+ * Kernel Space *
+ * *
+ ***************** ****************
+ User Space Himem * User Stack * * *
+ (typically 0xC0000000 3GB ) ***************** * *
+ * Shared Libs * * Next Process *
+ ***************** * to *
+ * * <== * Run * <==
+ * User Program * * *
+ * Data BSS * * *
+ * Text * * *
+ * Sections * * *
+ 0x00000000 ***************** ****************
+
+Now it is easy to see that on Intel it is quite easy to recognise a kernel
+address as being one greater than user space himem (in this case 0xC0000000),
+and addresses of less than this are the ones in the current running program on
+this processor (if an smp box).
+
+If using the virtual machine ( VM ) as a debugger it is quite difficult to
+know which user process is running as the address space you are looking at
+could be from any process in the run queue.
+
+The limitation of Intels addressing technique is that the linux
+kernel uses a very simple real address to virtual addressing technique
+of Real Address=Virtual Address-User Space Himem.
+This means that on Intel the kernel linux can typically only address
+Himem=0xFFFFFFFF-0xC0000000=1GB & this is all the RAM these machines
+can typically use.
+
+They can lower User Himem to 2GB or lower & thus be
+able to use 2GB of RAM however this shrinks the maximum size
+of User Space from 3GB to 2GB they have a no win limit of 4GB unless
+they go to 64 Bit.
+
+
+On 390 our limitations & strengths make us slightly different.
+For backward compatibility we are only allowed use 31 bits (2GB)
+of our 32 bit addresses, however, we use entirely separate address
+spaces for the user & kernel.
+
+This means we can support 2GB of non Extended RAM on s/390, & more
+with the Extended memory management swap device &
+currently 4TB of physical memory currently on z/Architecture.
+
+
+Address Spaces on Linux for s/390 & z/Architecture
+==================================================
+
+Our addressing scheme is basically as follows::
+
+ Primary Space Home Space
+ Himem 0x7fffffff 2GB on s/390 ***************** ****************
+ currently 0x3ffffffffff (2^42)-1 * User Stack * * *
+ on z/Architecture. ***************** * *
+ * Shared Libs * * *
+ ***************** * *
+ * * * Kernel *
+ * User Program * * *
+ * Data BSS * * *
+ * Text * * *
+ * Sections * * *
+ 0x00000000 ***************** ****************
+
+This also means that we need to look at the PSW problem state bit and the
+addressing mode to decide whether we are looking at user or kernel space.
+
+User space runs in primary address mode (or access register mode within
+the vdso code).
+
+The kernel usually also runs in home space mode, however when accessing
+user space the kernel switches to primary or secondary address mode if
+the mvcos instruction is not available or if a compare-and-swap (futex)
+instruction on a user space address is performed.
+
+When also looking at the ASCE control registers, this means:
+
+User space:
+
+- runs in primary or access register mode
+- cr1 contains the user asce
+- cr7 contains the user asce
+- cr13 contains the kernel asce
+
+Kernel space:
+
+- runs in home space mode
+- cr1 contains the user or kernel asce
+
+ - the kernel asce is loaded when a uaccess requires primary or
+ secondary address mode
+
+- cr7 contains the user or kernel asce, (changed with set_fs())
+- cr13 contains the kernel asce
+
+In case of uaccess the kernel changes to:
+
+- primary space mode in case of a uaccess (copy_to_user) and uses
+ e.g. the mvcp instruction to access user space. However the kernel
+ will stay in home space mode if the mvcos instruction is available
+- secondary space mode in case of futex atomic operations, so that the
+ instructions come from primary address space and data from secondary
+ space
+
+In case of KVM, the kernel runs in home space mode, but cr1 gets switched
+to contain the gmap asce before the SIE instruction gets executed. When
+the SIE instruction is finished, cr1 will be switched back to contain the
+user asce.
+
+
+Virtual Addresses on s/390 & z/Architecture
+===========================================
+
+A virtual address on s/390 is made up of 3 parts
+The SX (segment index, roughly corresponding to the PGD & PMD in Linux
+terminology) being bits 1-11.
+
+The PX (page index, corresponding to the page table entry (pte) in Linux
+terminology) being bits 12-19.
+
+The remaining bits BX (the byte index are the offset in the page )
+i.e. bits 20 to 31.
+
+On z/Architecture in linux we currently make up an address from 4 parts.
+
+- The region index bits (RX) 0-32 we currently use bits 22-32
+- The segment index (SX) being bits 33-43
+- The page index (PX) being bits 44-51
+- The byte index (BX) being bits 52-63
+
+Notes:
+ 1) s/390 has no PMD so the PMD is really the PGD also.
+ A lot of this stuff is defined in pgtable.h.
+
+ 2) Also seeing as s/390's page indexes are only 1k in size
+ (bits 12-19 x 4 bytes per pte ) we use 1 ( page 4k )
+ to make the best use of memory by updating 4 segment indices
+ entries each time we mess with a PMD & use offsets
+ 0,1024,2048 & 3072 in this page as for our segment indexes.
+ On z/Architecture our page indexes are now 2k in size
+ ( bits 12-19 x 8 bytes per pte ) we do a similar trick
+ but only mess with 2 segment indices each time we mess with
+ a PMD.
+
+ 3) As z/Architecture supports up to a massive 5-level page table lookup we
+ can only use 3 currently on Linux ( as this is all the generic kernel
+ currently supports ) however this may change in future
+ this allows us to access ( according to my sums )
+ 4TB of virtual storage per process i.e.
+ 4096*512(PTES)*1024(PMDS)*2048(PGD) = 4398046511104 bytes,
+ enough for another 2 or 3 of years I think :-).
+ to do this we use a region-third-table designation type in
+ our address space control registers.

+
+The Linux for s/390 & z/Architecture Kernel Task Structure
+==========================================================
+Each process/thread under Linux for S390 has its own kernel task_struct
+defined in linux/include/linux/sched.h
+The S390 on initialisation & resuming of a process on a cpu sets
+the __LC_KERNEL_STACK variable in the spare prefix area for this cpu
+(which we use for per-processor globals).
+
+The kernel stack pointer is intimately tied with the task structure for
+each processor as follows::
+
+ s/390
+ ************************
+ * 1 page kernel stack *
+ * ( 4K ) *
+ ************************
+ * 1 page task_struct *
+ * ( 4K ) *
+ 8K aligned ************************
+
+ z/Architecture
+ ************************
+ * 2 page kernel stack *
+ * ( 8K ) *
+ ************************
+ * 2 page task_struct *
+ * ( 8K ) *
+ 16K aligned ************************
+
+What this means is that we don't need to dedicate any register or global
+variable to point to the current running process & can retrieve it with the
+following very simple construct for s/390 & one very similar for
+z/Architecture::
+
+ static inline struct task_struct * get_current(void)
+ {
+ struct task_struct *current;
+ __asm__("lhi %0,-8192\n\t"
+ "nr %0,15"
+ : "=r" (current) );
+ return current;
+ }
+
+i.e. just anding the current kernel stack pointer with the mask -8192.
+Thankfully because Linux doesn't have support for nested IO interrupts
+& our devices have large buffers can survive interrupts being shut for
+short amounts of time we don't need a separate stack for interrupts.
+
+
+
+
+Register Usage & Stackframes on Linux for s/390 & z/Architecture
+=================================================================
+Overview:
+---------
+This is the code that gcc produces at the top & the bottom of
+each function. It usually is fairly consistent & similar from
+function to function & if you know its layout you can probably
+make some headway in finding the ultimate cause of a problem
+after a crash without a source level debugger.
+
+Note: To follow stackframes requires a knowledge of C or Pascal &
+limited knowledge of one assembly language.
+
+It should be noted that there are some differences between the
+s/390 and z/Architecture stack layouts as the z/Architecture stack layout
+didn't have to maintain compatibility with older linkage formats.
+
+Glossary:
+---------
+alloca:
+ This is a built in compiler function for runtime allocation
+ of extra space on the callers stack which is obviously freed
+ up on function exit ( e.g. the caller may choose to allocate nothing
+ of a buffer of 4k if required for temporary purposes ), it generates
+ very efficient code ( a few cycles ) when compared to alternatives
+ like malloc.
+
+automatics:
+ These are local variables on the stack, i.e they aren't in registers &
+ they aren't static.
+
+back-chain:
+ This is a pointer to the stack pointer before entering a
+ framed functions ( see frameless function ) prologue got by
+ dereferencing the address of the current stack pointer,
+ i.e. got by accessing the 32 bit value at the stack pointers
+ current location.
+
+base-pointer:
+ This is a pointer to the back of the literal pool which
+ is an area just behind each procedure used to store constants
+ in each function.
+
+call-clobbered:
+ The caller probably needs to save these registers if there
+ is something of value in them, on the stack or elsewhere before making a
+ call to another procedure so that it can restore it later.
+
+epilogue:
+ The code generated by the compiler to return to the caller.
+
+frameless-function:
+ A frameless function in Linux for s390 & z/Architecture is one which doesn't
+ need more than the register save area (96 bytes on s/390, 160 on z/Architecture)
+ given to it by the caller.
+
+ A frameless function never:
+
+ 1) Sets up a back chain.
+ 2) Calls alloca.
+ 3) Calls other normal functions
+ 4) Has automatics.
+
+GOT-pointer:
+ This is a pointer to the global-offset-table in ELF
+ ( Executable Linkable Format, Linux'es most common executable format ),
+ all globals & shared library objects are found using this pointer.
+
+lazy-binding
+ ELF shared libraries are typically only loaded when routines in the shared
+ library are actually first called at runtime. This is lazy binding.
+
+procedure-linkage-table
+ This is a table found from the GOT which contains pointers to routines
+ in other shared libraries which can't be called to by easier means.
+
+prologue:
+ The code generated by the compiler to set up the stack frame.
+
+outgoing-args:
+ This is extra area allocated on the stack of the calling function if the
+ parameters for the callee's cannot all be put in registers, the same
+ area can be reused by each function the caller calls.
+
+routine-descriptor:
+ A COFF executable format based concept of a procedure reference
+ actually being 8 bytes or more as opposed to a simple pointer to the routine.
+ This is typically defined as follows:
+
+ - Routine Descriptor offset 0=Pointer to Function
+ - Routine Descriptor offset 4=Pointer to Table of Contents
+
+ The table of contents/TOC is roughly equivalent to a GOT pointer.
+ & it means that shared libraries etc. can be shared between several
+ environments each with their own TOC.
+
+static-chain:
+ This is used in nested functions a concept adopted from pascal
+ by gcc not used in ansi C or C++ ( although quite useful ), basically it
+ is a pointer used to reference local variables of enclosing functions.
+ You might come across this stuff once or twice in your lifetime.
+
+ e.g.
+
+ The function below should return 11 though gcc may get upset & toss warnings
+ about unused variables::
+
+ int FunctionA(int a)
+ {
+ int b;
+ FunctionC(int c)
+ {
+ b=c+1;
+ }
+ FunctionC(10);
+ return(b);
+ }
+

+f4 z/Architecture argument 2 saved
+f6 z/Architecture argument 3 saved
+======== ========================================== ===============
+
+The remaining floating points
+f1,f3,f5 f7-f15 are call-clobbered.
+
+Notes:
+------
+1) The only requirement is that registers which are used
+ by the callee are saved, e.g. the compiler is perfectly
+ capable of using r11 for purposes other than a frame a
+ frame pointer if a frame pointer is not needed.
+2) In functions with variable arguments e.g. printf the calling procedure
+ is identical to one without variable arguments & the same number of
+ parameters. However, the prologue of this function is somewhat more
+ hairy owing to it having to move these parameters to the stack to
+ get va_start, va_arg & va_end to work.
+3) Access registers are currently unused by gcc but are used in
+ the kernel. Possibilities exist to use them at the moment for
+ temporary storage but it isn't recommended.
+4) Only 4 of the floating point registers are used for
+ parameter passing as older machines such as G3 only have only 4
+ & it keeps the stack frame compatible with other compilers.
+ However with IEEE floating point emulation under linux on the
+ older machines you are free to use the other 12.
+5) A long long or double parameter cannot be have the
+ first 4 bytes in a register & the second four bytes in the
+ outgoing args area. It must be purely in the outgoing args
+ area if crossing this boundary.
+6) Floating point parameters are mixed with outgoing args
+ on the outgoing args area in the order the are passed in as parameters.
+7) Floating point arguments 2 & 3 are saved in the outgoing args area for
+ z/Architecture

+===============================
+
+Comments on the function test
+-----------------------------
+1) It didn't need to set up a pointer to the constant pool gpr13 as it is not
+ used ( :-( ).
+2) This is a frameless function & no stack is bought.
+3) The compiler was clever enough to recognise that it could return the
+ value in r2 as well as use it for the passed in parameter ( :-) ).
+4) The basr ( branch relative & save ) trick works as follows the instruction
+ has a special case with r0,r0 with some instruction operands is understood as
+ the literal value 0, some risc architectures also do this ). So now
+ we are branching to the next address & the address new program counter is
+ in r13,so now we subtract the size of the function prologue we have executed
+ the size of the literal pool to get to the top of the literal pool::
+
+

+64 bit z/Architecture code disassembly
+--------------------------------------
+
+If you understand the stuff above you'll understand the stuff
+below too so I'll avoid repeating myself & just say that
+some of the instructions have g's on the end of them to indicate
+they are 64 bit & the stack offsets are a bigger,
+the only other difference you'll find between 32 & 64 bit is that
+we now use f4 & f6 for floating point arguments on 64 bit::

+
+Compiling programs for debugging on Linux for s/390 & z/Architecture
+====================================================================
+-gdwarf-2 now works it should be considered the default debugging
+format for s/390 & z/Architecture as it is more reliable for debugging
+shared libraries, normal -g debugging works much better now
+Thanks to the IBM java compiler developers bug reports.
+
+This is typically done adding/appending the flags -g or -gdwarf-2 to the
+CFLAGS & LDFLAGS variables Makefile of the program concerned.
+
+If using gdb & you would like accurate displays of registers &
+stack traces compile without optimisation i.e make sure
+that there is no -O2 or similar on the CFLAGS line of the Makefile &
+the emitted gcc commands, obviously this will produce worse code
+( not advisable for shipment ) but it is an aid to the debugging process.
+
+This aids debugging because the compiler will copy parameters passed in
+in registers onto the stack so backtracing & looking at passed in
+parameters will work, however some larger programs which use inline functions
+will not compile without optimisation.
+
+Debugging with optimisation has since much improved after fixing
+some bugs, please make sure you are using gdb-5.0 or later developed
+after Nov'2000.
+
+
+
+Debugging under VM
+==================
+
+Notes
+-----
+Addresses & values in the VM debugger are always hex never decimal
+Address ranges are of the format <HexValue1>-<HexValue2> or
+<HexValue1>.<HexValue2>
+For example, the address range 0x2000 to 0x3000 can be described as 2000-3000
+or 2000.1000
+
+The VM Debugger is case insensitive.
+
+VM's strengths are usually other debuggers weaknesses you can get at any
+resource no matter how sensitive e.g. memory management resources, change
+address translation in the PSW. For kernel hacking you will reap dividends if
+you get good at it.
+
+The VM Debugger displays operators but not operands, and also the debugger
+displays useful information on the same line as the author of the code probably
+felt that it was a good idea not to go over the 80 columns on the screen.
+This isn't as unintuitive as it may seem as the s/390 instructions are easy to
+decode mentally and you can make a good guess at a lot of them as all the
+operands are nibble (half byte aligned).
+So if you have an objdump listing by hand, it is quite easy to follow, and if
+you don't have an objdump listing keep a copy of the s/390 Reference Summary
+or alternatively the s/390 principles of operation next to you.
+e.g. even I can guess that
+0001AFF8' LR 180F CC 0
+is a ( load register ) lr r0,r15
+
+Also it is very easy to tell the length of a 390 instruction from the 2 most
+significant bits in the instruction (not that this info is really useful except
+if you are trying to make sense of a hexdump of code).
+Here is a table
+
+======================= ==================
+Bits Instruction Length
+======================= ==================
+00 2 Bytes
+01 4 Bytes
+10 4 Bytes
+11 6 Bytes
+======================= ==================
+
+The debugger also displays other useful info on the same line such as the
+addresses being operated on destination addresses of branches & condition codes.
+e.g.::
+
+ 00019736' AHI A7DAFF0E CC 1
+ 000198BA' BRC A7840004 -> 000198C2' CC 0
+ 000198CE' STM 900EF068 >> 0FA95E78 CC 2
+
+
+
+Useful VM debugger commands
+---------------------------
+
+I suppose I'd better mention this before I start
+to list the current active traces do::
+
+ Q TR
+
+there can be a maximum of 255 of these per set
+( more about trace sets later ).
+
+To stop traces issue a::
+
+ TR END.
+
+To delete a particular breakpoint issue::
+
+ TR DEL <breakpoint number>
+
+The PA1 key drops to CP mode so you can issue debugger commands,
+Doing alt c (on my 3270 console at least ) clears the screen.
+
+hitting b <enter> comes back to the running operating system
+from cp mode ( in our case linux ).
+
+It is typically useful to add shortcuts to your profile.exec file
+if you have one ( this is roughly equivalent to autoexec.bat in DOS ).
+file here are a few from mine::
+
+ /* this gives me command history on issuing f12 */
+ set pf12 retrieve
+ /* this continues */
+ set pf8 imm b
+ /* goes to trace set a */
+ set pf1 imm tr goto a
+ /* goes to trace set b */
+ set pf2 imm tr goto b
+ /* goes to trace set c */
+ set pf3 imm tr goto c
+
+
+
+Instruction Tracing
+-------------------
+Setting a simple breakpoint::
+
+ TR I PSWA <address>
+
+To debug a particular function try::
+
+ TR I R <function address range>
+ TR I on its own will single step.
+ TR I DATA <MNEMONIC> <OPTIONAL RANGE> will trace for particular mnemonics
+
+e.g.::
+
+ TR I DATA 4D R 0197BC.4000
+
+will trace for BAS'es ( opcode 4D ) in the range 0197BC.4000
+
+if you were inclined you could add traces for all branch instructions &
+suffix them with the run prefix so you would have a backtrace on screen
+when a program crashes::
+
+ TR BR <INTO OR FROM> will trace branches into or out of an address.
+
+e.g.::
+
+ TR BR INTO 0
+
+is often quite useful if a program is getting awkward & deciding
+to branch to 0 & crashing as this will stop at the address before in jumps to 0.
+
+::
+
+ TR I R <address range> RUN cmd d g
+
+single steps a range of addresses but stays running &
+displays the gprs on each step.
+
+
+
+Displaying & modifying Registers
+--------------------------------
+D G
+ will display all the gprs
+
+Adding a extra G to all the commands is necessary to access the full 64 bit
+content in VM on z/Architecture. Obviously this isn't required for access
+registers as these are still 32 bit.
+
+e.g.
+
+DGG
+ instead of DG
+
+D X
+ will display all the control registers
+D AR
+ will display all the access registers
+D AR4-7
+ will display access registers 4 to 7
+CPU ALL D G
+ will display the GRPS of all CPUS in the configuration
+D PSW
+ will display the current PSW
+st PSW 2000
+ will put the value 2000 into the PSW & cause crash your machine.
+D PREFIX
+ displays the prefix offset
+
+
+Displaying Memory
+-----------------
+To display memory mapped using the current PSW's mapping try::
+
+ D <range>
+
+To make VM display a message each time it hits a particular address and
+continue try:
+
+D I<range>
+ will disassemble/display a range of instructions.
+
+ST addr 32 bit word
+ will store a 32 bit aligned address
+D T<range>
+ will display the EBCDIC in an address (if you are that way inclined)
+D R<range>
+ will display real addresses ( without DAT ) but with prefixing.
+
+There are other complex options to display if you need to get at say home space
+but are in primary space the easiest thing to do is to temporarily
+modify the PSW to the other addressing mode, display the stuff & then
+restore it.
+
+
+
+Hints
+-----
+If you want to issue a debugger command without halting your virtual machine
+with the PA1 key try prefixing the command with #CP e.g.::
+
+ #cp tr i pswa 2000
+
+also suffixing most debugger commands with RUN will cause them not
+to stop just display the mnemonic at the current instruction on the console.
+
+If you have several breakpoints you want to put into your program &
+you get fed up of cross referencing with System.map
+you can do the following trick for several symbols.
+
+::
+
+ grep do_signal System.map
+
+which emits the following among other things::
+
+ 0001f4e0 T do_signal
+
+now you can do::
+
+ TR I PSWA 0001f4e0 cmd msg * do_signal
+
+This sends a message to your own console each time do_signal is entered.
+( As an aside I wrote a perl script once which automatically generated a REXX
+script with breakpoints on every kernel procedure, this isn't a good idea
+because there are thousands of these routines & VM can only set 255 breakpoints
+at a time so you nearly had to spend as long pruning the file down as you would
+entering the msgs by hand), however, the trick might be useful for a single
+object file. In the 3270 terminal emulator x3270 there is a very useful option
+in the file menu called "Save Screen In File" - this is very good for keeping a
+copy of traces.
+
+From CMS help <command name> will give you online help on a particular command.
+e.g.::
+
+ HELP DISPLAY
+
+Also CP has a file called profile.exec which automatically gets called
+on startup of CMS ( like autoexec.bat ), keeping on a DOS analogy session
+CP has a feature similar to doskey, it may be useful for you to
+use profile.exec to define some keystrokes.
+
+SET PF9 IMM B
+ This does a single step in VM on pressing F8.

+ This sets up the ^ key.
+ which can be used for ^c (ctrl-c),^z (ctrl-z) which can't be typed
+ directly into some 3270 consoles.
+
+SET PF11 ^-
+ This types the starting keystrokes for a sysrq see SysRq below.
+SET PF12 RETRIEVE
+ This retrieves command history on pressing F12.
+
+
+Sometimes in VM the display is set up to scroll automatically this
+can be very annoying if there are messages you wish to look at
+to stop this do
+
+TERM MORE 255 255
+ This will nearly stop automatic screen updates, however it will
+ cause a denial of service if lots of messages go to the 3270 console,
+ so it would be foolish to use this as the default on a production machine.
+
+
+Tracing particular processes
+----------------------------
+The kernel's text segment is intentionally at an address in memory that it will
+very seldom collide with text segments of user programs ( thanks Martin ),
+this simplifies debugging the kernel.
+However it is quite common for user processes to have addresses which collide
+this can make debugging a particular process under VM painful under normal
+circumstances as the process may change when doing a::
+
+ TR I R <address range>.
+
+Thankfully after reading VM's online help I figured out how to debug
+I particular process.
+
+Your first problem is to find the STD ( segment table designation )
+of the program you wish to debug.
+There are several ways you can do this here are a few
+
+Run::
+
+ objdump --syms <program to be debugged> | grep main
+
+To get the address of main in the program. Then::
+
+ tr i pswa <address of main>
+
+Start the program, if VM drops to CP on what looks like the entry
+point of the main function this is most likely the process you wish to debug.
+Now do a D X13 or D XG13 on z/Architecture.
+
+On 31 bit the STD is bits 1-19 ( the STO segment table origin )
+& 25-31 ( the STL segment table length ) of CR13.
+
+now type::
+
+ TR I R STD <CR13's value> 0.7fffffff
+
+e.g.::
+
+ TR I R STD 8F32E1FF 0.7fffffff
+
+Another very useful variation is::
+
+ TR STORE INTO STD <CR13's value> <address range>
+
+for finding out when a particular variable changes.
+
+An alternative way of finding the STD of a currently running process
+is to do the following, ( this method is more complex but
+could be quite convenient if you aren't updating the kernel much &
+so your kernel structures will stay constant for a reasonable period of
+time ).
+
+::
+
+ grep task /proc/<pid>/status
+
+from this you should see something like::
+
+ task: 0f160000 ksp: 0f161de8 pt_regs: 0f161f68
+
+This now gives you a pointer to the task structure.
+
+Now make::
+
+ CC:="s390-gcc -g" kernel/sched.s
+
+To get the task_struct stabinfo.
+
+( task_struct is defined in include/linux/sched.h ).
+
+Now we want to look at
+task->active_mm->pgd
+
+on my machine the active_mm in the task structure stab is
+active_mm:(4,12),672,32
+
+its offset is 672/8=84=0x54
+
+the pgd member in the mm_struct stab is
+pgd:(4,6)=*(29,5),96,32
+so its offset is 96/8=12=0xc
+
+so we'll::
+
+ hexdump -s 0xf160054 /dev/mem | more
+
+i.e. task_struct+active_mm offset
+to look at the active_mm member::
+
+ f160054 0fee cc60 0019 e334 0000 0000 0000 0011
+
+::
+
+ hexdump -s 0x0feecc6c /dev/mem | more
+
+i.e. active_mm+pgd offset::
+
+ feecc6c 0f2c 0000 0000 0001 0000 0001 0000 0010
+
+we get something like
+now do::
+
+ TR I R STD <pgd|0x7f> 0.7fffffff
+
+i.e. the 0x7f is added because the pgd only
+gives the page table origin & we need to set the low bits
+to the maximum possible segment table length.
+
+::
+
+ TR I R STD 0f2c007f 0.7fffffff
+
+on z/Architecture you'll probably need to do::
+
+ TR I R STD <pgd|0x7> 0.ffffffffffffffff
+
+to set the TableType to 0x1 & the Table length to 3.
+
+
+
+Tracing Program Exceptions
+--------------------------
+If you get a crash which says something like
+illegal operation or specification exception followed by a register dump
+You can restart linux & trace these using the tr prog <range or value> trace
+option.
+
+
+The most common ones you will normally be tracing for is:
+
+- 1=operation exception
+- 2=privileged operation exception
+- 4=protection exception
+- 5=addressing exception
+- 6=specification exception
+- 10=segment translation exception
+- 11=page translation exception
+
+The full list of these is on page 22 of the current s/390 Reference Summary.
+e.g.
+
+tr prog 10 will trace segment translation exceptions.
+
+tr prog on its own will trace all program interruption codes.
+
+Trace Sets
+----------
+On starting VM you are initially in the INITIAL trace set.
+You can do a Q TR to verify this.
+If you have a complex tracing situation where you wish to wait for instance
+till a driver is open before you start tracing IO, but know in your
+heart that you are going to have to make several runs through the code till you
+have a clue whats going on.
+
+What you can do is::
+
+ TR I PSWA <Driver open address>
+
+hit b to continue till breakpoint
+
+reach the breakpoint
+
+now do your::
+
+ TR GOTO B
+ TR IO 7c08-7c09 inst int run
+
+or whatever the IO channels you wish to trace are & hit b
+
+To got back to the initial trace set do::
+
+ TR GOTO INITIAL
+
+& the TR I PSWA <Driver open address> will be the only active breakpoint again.
+
+
+Tracing linux syscalls under VM
+-------------------------------
+Syscalls are implemented on Linux for S390 by the Supervisor call instruction
+(SVC). There 256 possibilities of these as the instruction is made up of a 0xA
+opcode and the second byte being the syscall number. They are traced using the
+simple command::
+
+ TR SVC <Optional value or range>
+
+the syscalls are defined in linux/arch/s390/include/asm/unistd.h
+e.g. to trace all file opens just do::
+
+ TR SVC 5 ( as this is the syscall number of open )
+
+
+SMP Specific commands
+---------------------
+To find out how many cpus you have
+Q CPUS displays all the CPU's available to your virtual machine
+To find the cpu that the current cpu VM debugger commands are being directed at
+do Q CPU to change the current cpu VM debugger commands are being directed at
+do::
+
+ CPU <desired cpu no>
+
+On a SMP guest issue a command to all CPUs try prefixing the command with cpu
+all. To issue a command to a particular cpu try cpu <cpu number> e.g.::
+
+ CPU 01 TR I R 2000.3000
+
+If you are running on a guest with several cpus & you have a IO related problem
+& cannot follow the flow of code but you know it isn't smp related.
+
+from the bash prompt issue::
+
+ shutdown -h now or halt.
+
+do a::
+
+ Q CPUS
+
+to find out how many cpus you have detach each one of them from cp except
+cpu 0 by issuing a::
+
+ DETACH CPU 01-(number of cpus in configuration)
+
+& boot linux again.
+
+TR SIGP
+ will trace inter processor signal processor instructions.
+
+DEFINE CPU 01-(number in configuration)
+ will get your guests cpus back.
+
+
+Help for displaying ascii textstrings
+-------------------------------------
+On the very latest VM Nucleus'es VM can now display ascii
+( thanks Neale for the hint ) by doing::
+
+ D TX<lowaddr>.<len>
+
+e.g.::
+
+ D TX0.100
+
+Alternatively
+=============
+Under older VM debuggers (I love EBDIC too) you can use following little
+program which converts a command line of hex digits to ascii text. It can be
+compiled under linux and you can copy the hex digits from your x3270 terminal
+to your xterm if you are debugging from a linuxbox.
+
+This is quite useful when looking at a parameter passed in as a text string
+under VM ( unless you are good at decoding ASCII in your head ).
+
+e.g. consider tracing an open syscall::
+
+ TR SVC 5
+
+We have stopped at a breakpoint::
+
+ 000151B0' SVC 0A05 -> 0001909A' CC 0
+
+D 20.8 to check the SVC old psw in the prefix area and see was it from userspace
+(for the layout of the prefix area consult the "Fixed Storage Locations"
+chapter of the s/390 Reference Summary if you have it available).
+
+::
+
+ V00000020 070C2000 800151B2
+
+The problem state bit wasn't set & it's also too early in the boot sequence
+for it to be a userspace SVC if it was we would have to temporarily switch the
+psw to user space addressing so we could get at the first parameter of the open
+in gpr2.
+
+Next do a::
+
+ D G2
+ GPR 2 = 00014CB4
+
+Now display what gpr2 is pointing to::
+
+ D 00014CB4.20
+ V00014CB4 2F646576 2F636F6E 736F6C65 00001BF5
+ V00014CC4 FC00014C B4001001 E0001000 B8070707
+
+Now copy the text till the first 00 hex ( which is the end of the string
+to an xterm & do hex2ascii on it::
+
+ hex2ascii 2F646576 2F636F6E 736F6C65 00
+
+outputs::
+
+ Decoded Hex:=/ d e v / c o n s o l e 0x00
+
+We were opening the console device,
+
+You can compile the code below yourself for practice :-),
+
+::

+
+Stack tracing under VM
+----------------------
+A basic backtrace
+-----------------
+
+Here are the tricks I use 9 out of 10 times it works pretty well,
+
+When your backchain reaches a dead end
+--------------------------------------
+This can happen when an exception happens in the kernel and the kernel is
+entered twice. If you reach the NULL pointer at the end of the back chain you
+should be able to sniff further back if you follow the following tricks.
+1) A kernel address should be easy to recognise since it is in
+primary space & the problem state bit isn't set & also
+The Hi bit of the address is set.
+2) Another backchain should also be easy to recognise since it is an
+address pointing to another address approximately 100 bytes or 0x70 hex
+behind the current stackpointer.
+
+
+Here is some practice.
+
+boot the kernel & hit PA1 at some random time
+
+d g to display the gprs, this should display something like::
+
+ GPR 0 = 00000001 00156018 0014359C 00000000
+ GPR 4 = 00000001 001B8888 000003E0 00000000
+ GPR 8 = 00100080 00100084 00000000 000FE000
+ GPR 12 = 00010400 8001B2DC 8001B36A 000FFED8
+
+Note that GPR14 is a return address but as we are real men we are going to
+trace the stack.
+display 0x40 bytes after the stack pointer::
+
+ V000FFED8 000FFF38 8001B838 80014C8E 000FFF38
+ V000FFEE8 00000000 00000000 000003E0 00000000
+ V000FFEF8 00100080 00100084 00000000 000FE000
+ V000FFF08 00010400 8001B2DC 8001B36A 000FFED8
+
+
+Ah now look at whats in sp+56 (sp+0x38) this is 8001B36A our saved r14 if
+you look above at our stackframe & also agrees with GPR14.
+
+now backchain::
+
+ d 000FFF38.40
+
+we now are taking the contents of SP to get our first backchain::
+
+ V000FFF38 000FFFA0 00000000 00014995 00147094
+ V000FFF48 00147090 001470A0 000003E0 00000000
+ V000FFF58 00100080 00100084 00000000 001BF1D0
+ V000FFF68 00010400 800149BA 80014CA6 000FFF38
+
+This displays a 2nd return address of 80014CA6
+
+now do::
+
+ d 000FFFA0.40
+
+for our 3rd backchain::
+
+ V000FFFA0 04B52002 0001107F 00000000 00000000
+ V000FFFB0 00000000 00000000 FF000000 0001107F
+ V000FFFC0 00000000 00000000 00000000 00000000
+ V000FFFD0 00010400 80010802 8001085A 000FFFA0
+
+
+our 3rd return address is 8001085A
+
+as the 04B52002 looks suspiciously like rubbish it is fair to assume that the
+kernel entry routines for the sake of optimisation don't set up a backchain.
+
+now look at System.map to see if the addresses make any sense::
+
+ grep -i 0001b3 System.map
+
+outputs among other things::
+
+ 0001b304 T cpu_idle
+
+so 8001B36A
+is cpu_idle+0x66 ( quiet the cpu is asleep, don't wake it )
+
+::
+
+ grep -i 00014 System.map
+
+produces among other things::
+
+ 00014a78 T start_kernel
+
+so 0014CA6 is start_kernel+some hex number I can't add in my head.
+
+::
+
+ grep -i 00108 System.map
+
+this produces::
+
+ 00010800 T _stext
+
+so 8001085A is _stext+0x5a
+
+Congrats you've done your first backchain.
+
+
+
+s/390 & z/Architecture IO Overview
+==================================
+
+I am not going to give a course in 390 IO architecture as this would take me
+quite a while and I'm no expert. Instead I'll give a 390 IO architecture
+summary for Dummies. If you have the s/390 principles of operation available
+read this instead. If nothing else you may find a few useful keywords in here
+and be able to use them on a web search engine to find more useful information.
+
+Unlike other bus architectures modern 390 systems do their IO using mostly
+fibre optics and devices such as tapes and disks can be shared between several
+mainframes. Also S390 can support up to 65536 devices while a high end PC based
+system might be choking with around 64.
+
+Here is some of the common IO terminology:
+
+Subchannel:
+ This is the logical number most IO commands use to talk to an IO device. There
+ can be up to 0x10000 (65536) of these in a configuration, typically there are a
+ few hundred. Under VM for simplicity they are allocated contiguously, however
+ on the native hardware they are not. They typically stay consistent between
+ boots provided no new hardware is inserted or removed.
+
+ Under Linux for s390 we use these as IRQ's and also when issuing an IO command
+ (CLEAR SUBCHANNEL, HALT SUBCHANNEL, MODIFY SUBCHANNEL, RESUME SUBCHANNEL,
+ START SUBCHANNEL, STORE SUBCHANNEL and TEST SUBCHANNEL). We use this as the ID
+ of the device we wish to talk to. The most important of these instructions are
+ START SUBCHANNEL (to start IO), TEST SUBCHANNEL (to check whether the IO
+ completed successfully) and HALT SUBCHANNEL (to kill IO). A subchannel can have
+ up to 8 channel paths to a device, this offers redundancy if one is not
+ available.
+
+Device Number:
+ This number remains static and is closely tied to the hardware. There are 65536
+ of these, made up of a CHPID (Channel Path ID, the most significant 8 bits) and
+ another lsb 8 bits. These remain static even if more devices are inserted or
+ removed from the hardware. There is a 1 to 1 mapping between subchannels and
+ device numbers, provided devices aren't inserted or removed.
+
+Channel Control Words:
+ CCWs are linked lists of instructions initially pointed to by an operation
+ request block (ORB), which is initially given to Start Subchannel (SSCH)
+ command along with the subchannel number for the IO subsystem to process
+ while the CPU continues executing normal code.
+ CCWs come in two flavours, Format 0 (24 bit for backward compatibility) and
+ Format 1 (31 bit). These are typically used to issue read and write (and many
+ other) instructions. They consist of a length field and an absolute address
+ field.
+
+ Each IO typically gets 1 or 2 interrupts, one for channel end (primary status)
+ when the channel is idle, and the second for device end (secondary status).
+ Sometimes you get both concurrently. You check how the IO went on by issuing a
+ TEST SUBCHANNEL at each interrupt, from which you receive an Interruption
+ response block (IRB). If you get channel and device end status in the IRB
+ without channel checks etc. your IO probably went okay. If you didn't you
+ probably need to examine the IRB, extended status word etc.
+ If an error occurs, more sophisticated control units have a facility known as
+ concurrent sense. This means that if an error occurs Extended sense information
+ will be presented in the Extended status word in the IRB. If not you have to
+ issue a subsequent SENSE CCW command after the test subchannel.
+
+
+TPI (Test pending interrupt) can also be used for polled IO, but in
+multitasking multiprocessor systems it isn't recommended except for
+checking special cases (i.e. non looping checks for pending IO etc.).
+
+Store Subchannel and Modify Subchannel can be used to examine and modify
+operating characteristics of a subchannel (e.g. channel paths).
+
+Other IO related Terms:
+
+Sysplex:
+ S390's Clustering Technology
+QDIO:
+ S390's new high speed IO architecture to support devices such as gigabit
+ ethernet, this architecture is also designed to be forward compatible with
+ upcoming 64 bit machines.
+
+
+General Concepts
+----------------
+
+Input Output Processors (IOP's) are responsible for communicating between
+the mainframe CPU's & the channel & relieve the mainframe CPU's from the
+burden of communicating with IO devices directly, this allows the CPU's to
+concentrate on data processing.
+
+IOP's can use one or more links ( known as channel paths ) to talk to each
+IO device. It first checks for path availability & chooses an available one,
+then starts ( & sometimes terminates IO ).
+There are two types of channel path: ESCON & the Parallel IO interface.
+
+IO devices are attached to control units, control units provide the
+logic to interface the channel paths & channel path IO protocols to
+the IO devices, they can be integrated with the devices or housed separately
+& often talk to several similar devices ( typical examples would be raid
+controllers or a control unit which connects to 1000 3270 terminals )::

+ IOP = IP Processor
+ CU = Control Unit
+
+The 390 IO systems come in 2 flavours the current 390 machines support both
+
+The Older 360 & 370 Interface,sometimes called the Parallel I/O interface,
+sometimes called Bus-and Tag & sometimes Original Equipment Manufacturers
+Interface (OEMI).
+
+This byte wide Parallel channel path/bus has parity & data on the "Bus" cable
+and control lines on the "Tag" cable. These can operate in byte multiplex mode
+for sharing between several slow devices or burst mode and monopolize the
+channel for the whole burst. Up to 256 devices can be addressed on one of these
+cables. These cables are about one inch in diameter. The maximum unextended
+length supported by these cables is 125 Meters but this can be extended up to
+2km with a fibre optic channel extended such as a 3044. The maximum burst speed
+supported is 4.5 megabytes per second. However, some really old processors
+support only transfer rates of 3.0, 2.0 & 1.0 MB/sec.
+One of these paths can be daisy chained to up to 8 control units.
+
+
+ESCON if fibre optic it is also called FICON
+Was introduced by IBM in 1990. Has 2 fibre optic cables and uses either leds or
+lasers for communication at a signaling rate of up to 200 megabits/sec. As
+10bits are transferred for every 8 bits info this drops to 160 megabits/sec
+and to 18.6 Megabytes/sec once control info and CRC are added. ESCON only
+operates in burst mode.
+
+ESCONs typical max cable length is 3km for the led version and 20km for the
+laser version known as XDF (extended distance facility). This can be further
+extended by using an ESCON director which triples the above mentioned ranges.
+Unlike Bus & Tag as ESCON is serial it uses a packet switching architecture,
+the standard Bus & Tag control protocol is however present within the packets.
+Up to 256 devices can be attached to each control unit that uses one of these
+interfaces.
+
+Common 390 Devices include:
+Network adapters typically OSA2,3172's,2116's & OSA-E gigabit ethernet adapters,
+Consoles 3270 & 3215 (a teletype emulated under linux for a line mode console).
+DASD's direct access storage devices ( otherwise known as hard disks ).
+Tape Drives.
+CTC ( Channel to Channel Adapters ),
+ESCON or Parallel Cables used as a very high speed serial link
+between 2 machines.
+
+
+Debugging IO on s/390 & z/Architecture under VM
+===============================================
+
+Now we are ready to go on with IO tracing commands under VM
+
+A few self explanatory queries::
+
+ Q OSA
+ Q CTC
+ Q DISK ( This command is CMS specific )
+ Q DASD
+
+Q OSA on my machine returns::
+
+ OSA 7C08 ON OSA 7C08 SUBCHANNEL = 0000
+ OSA 7C09 ON OSA 7C09 SUBCHANNEL = 0001
+ OSA 7C14 ON OSA 7C14 SUBCHANNEL = 0002
+ OSA 7C15 ON OSA 7C15 SUBCHANNEL = 0003
+
+If you have a guest with certain privileges you may be able to see devices
+which don't belong to you. To avoid this, add the option V.
+e.g.::
+
+ Q V OSA
+
+Now using the device numbers returned by this command we will
+Trace the io starting up on the first device 7c08 & 7c09
+In our simplest case we can trace the
+start subchannels
+like TR SSCH 7C08-7C09
+or the halt subchannels
+or TR HSCH 7C08-7C09
+MSCH's ,STSCH's I think you can guess the rest
+
+A good trick is tracing all the IO's and CCWS and spooling them into the reader
+of another VM guest so he can ftp the logfile back to his own machine. I'll do
+a small bit of this and give you a look at the output.
+
+1) Spool stdout to VM reader::
+
+ SP PRT TO (another vm guest ) or * for the local vm guest
+
+2) Fill the reader with the trace::
+
+ TR IO 7c08-7c09 INST INT CCW PRT RUN
+
+3) Start up linux::
+
+ i 00c
+4) Finish the trace::
+
+ TR END
+
+5) close the reader::
+
+ C PRT
+
+6) list reader contents::
+
+ RDRLIST
+
+7) copy it to linux4's minidisk::
+
+ RECEIVE / LOG TXT A1 ( replace
+
+8)
+filel & press F11 to look at it
+You should see something like::
+
+ 00020942' SSCH B2334000 0048813C CC 0 SCH 0000 DEV 7C08
+ CPA 000FFDF0 PARM 00E2C9C4 KEY 0 FPI C0 LPM 80
+ CCW 000FFDF0 E4200100 00487FE8 0000 E4240100 ........
+ IDAL 43D8AFE8
+ IDAL 0FB76000
+ 00020B0A' I/O DEV 7C08 -> 000197BC' SCH 0000 PARM 00E2C9C4
+ 00021628' TSCH B2354000 >> 00488164 CC 0 SCH 0000 DEV 7C08
+ CCWA 000FFDF8 DEV STS 0C SCH STS 00 CNT 00EC
+ KEY 0 FPI C0 CC 0 CTLS 4007
+ 00022238' STSCH B2344000 >> 00488108 CC 0 SCH 0000 DEV 7C08
+
+If you don't like messing up your readed ( because you possibly booted from it )
+you can alternatively spool it to another readers guest.
+
+
+Other common VM device related commands
+---------------------------------------------
+These commands are listed only because they have
+been of use to me in the past & may be of use to
+you too. For more complete info on each of the commands
+use type HELP <command> from CMS.
+
+detaching devices::
+
+ DET <devno range>
+ ATT <devno range> <guest>
+
+attach a device to guest * for your own guest
+
+READY <devno>
+ cause VM to issue a fake interrupt.
+
+The VARY command is normally only available to VM administrators::
+
+ VARY ON PATH <path> TO <devno range>
+ VARY OFF PATH <PATH> FROM <devno range>
+
+This is used to switch on or off channel paths to devices.
+
+Q CHPID <channel path ID>
+ This displays state of devices using this channel path
+
+D SCHIB <subchannel>
+ This displays the subchannel information SCHIB block for the device.
+ this I believe is also only available to administrators.
+
+DEFINE CTC <devno>
+ defines a virtual CTC channel to channel connection
+ 2 need to be defined on each guest for the CTC driver to use.
+
+COUPLE devno userid remote devno
+ Joins a local virtual device to a remote virtual device
+ ( commonly used for the CTC driver ).
+
+Building a VM ramdisk under CMS which linux can use::
+
+ def vfb-<blocksize> <subchannel> <number blocks>
+
+blocksize is commonly 4096 for linux.
+
+Formatting it::
+
+ format <subchannel> <driver letter e.g. x> (blksize <blocksize>
+
+Sharing a disk between multiple guests::
+
+ LINK userid devno1 devno2 mode password
+
+
+
+GDB on S390
+===========
+N.B. if compiling for debugging gdb works better without optimisation
+( see Compiling programs for debugging )
+
+invocation
+----------
+gdb <victim program> <optional corefile>
+
+Online help
+-----------
+help: gives help on commands
+
+e.g.::
+
+ help
+ help display
+
+Note gdb's online help is very good use it.
+
+
+Assembly
+--------
+info registers:
+ displays registers other than floating point.
+
+info all-registers:
+ displays floating points as well.
+
+disassemble:
+ disassembles
+
+e.g.::
+
+ disassemble without parameters will disassemble the current function
+ disassemble $pc $pc+10
+
+Viewing & modifying variables
+-----------------------------
+print or p:
+ displays variable or register
+
+e.g. p/x $sp will display the stack pointer
+
+display:
+ prints variable or register each time program stops
+
+e.g.::
+
+ display/x $pc will display the program counter
+ display argc
+
+undisplay:
+ undo's display's
+
+info breakpoints:
+ shows all current breakpoints
+
+info stack:
+ shows stack back trace (if this doesn't work too well, I'll show
+ you the stacktrace by hand below).
+
+info locals:
+ displays local variables.
+
+info args:
+ display current procedure arguments.
+
+set args:
+ will set argc & argv each time the victim program is invoked
+
+e.g.::
+
+ set <variable>=value
+ set argc=100
+ set $pc=0
+
+
+
+Modifying execution
+-------------------
+step:
+ steps n lines of sourcecode
+
+step
+ steps 1 line.
+
+step 100
+ steps 100 lines of code.
+
+next:
+ like step except this will not step into subroutines
+
+stepi:
+ steps a single machine code instruction.
+
+e.g.::
+
+ stepi 100
+
+nexti:
+ steps a single machine code instruction but will not step into
+ subroutines.
+
+finish:
+ will run until exit of the current routine
+
+run:
+ (re)starts a program
+
+cont:
+ continues a program
+
+quit:
+ exits gdb.
+
+
+breakpoints
+------------
+
+break
+ sets a breakpoint
+
+e.g.::
+
+ break main
+ break *$pc
+ break *0x400618
+
+Here's a really useful one for large programs
+
+rbr
+ Set a breakpoint for all functions matching REGEXP
+
+e.g.::
+
+ rbr 390
+
+will set a breakpoint with all functions with 390 in their name.
+
+info breakpoints
+ lists all breakpoints
+
+delete:
+ delete breakpoint by number or delete them all
+
+e.g.
+
+delete 1
+ will delete the first breakpoint
+
+
+delete
+ will delete them all
+
+watch:
+ This will set a watchpoint ( usually hardware assisted ),
+
+This will watch a variable till it changes
+
+e.g.
+
+watch cnt
+ will watch the variable cnt till it changes.
+
+As an aside unfortunately gdb's, architecture independent watchpoint code
+is inconsistent & not very good, watchpoints usually work but not always.
+
+info watchpoints:
+ Display currently active watchpoints
+
+condition: ( another useful one )
+ Specify breakpoint number N to break only if COND is true.
+
+Usage is `condition N COND`, where N is an integer and COND is an
+expression to be evaluated whenever breakpoint N is reached.
+
+
+
+User defined functions/macros
+-----------------------------
+define: ( Note this is very very useful,simple & powerful )
+
+usage define <name> <list of commands> end
+
+examples which you should consider putting into .gdbinit in your home
+directory::
+
+ define d
+ stepi
+ disassemble $pc $pc+10
+ end
+ define e
+ nexti
+ disassemble $pc $pc+10
+ end
+
+
+Other hard to classify stuff
+----------------------------
+signal n:
+ sends the victim program a signal.
+
+e.g. `signal 3` will send a SIGQUIT.
+
+info signals:
+ what gdb does when the victim receives certain signals.
+
+list:
+
+e.g.:
+
+list
+ lists current function source
+list 1,10
+ list first 10 lines of current file.
+
+list test.c:1,10
+
+
+directory:
+ Adds directories to be searched for source if gdb cannot find the source.
+ (note it is a bit sensitive about slashes)
+
+e.g. To add the root of the filesystem to the searchpath do::
+
+ directory //
+
+
+call <function>
+This calls a function in the victim program, this is pretty powerful
+e.g.
+(gdb) call printf("hello world")
+outputs:
+$1 = 11
+
+You might now be thinking that the line above didn't work, something extra had
+to be done.
+(gdb) call fflush(stdout)
+hello world$2 = 0
+As an aside the debugger also calls malloc & free under the hood
+to make space for the "hello world" string.
+
+
+
+hints
+-----
+1) command completion works just like bash
+ ( if you are a bad typist like me this really helps )
+
+e.g. hit br <TAB> & cursor up & down :-).
+
+2) if you have a debugging problem that takes a few steps to recreate
+put the steps into a file called .gdbinit in your current working directory
+if you have defined a few extra useful user defined commands put these in
+your home directory & they will be read each time gdb is launched.
+
+A typical .gdbinit file might be.::
+
+ break main
+ run
+ break runtime_exception
+ cont
+
+
+stack chaining in gdb by hand
+-----------------------------
+This is done using a the same trick described for VM::
+
+ p/x (*($sp+56))&0x7fffffff
+
+get the first backchain.
+
+For z/Architecture
+Replace 56 with 112 & ignore the &0x7fffffff
+in the macros below & do nasty casts to longs like the following
+as gdb unfortunately deals with printed arguments as ints which
+messes up everything.
+
+i.e. here is a 3rd backchain dereference::
+
+ p/x *(long *)(***(long ***)$sp+112)
+
+
+this outputs::
+
+ $5 = 0x528f18
+
+on my machine.
+
+Now you can use::
+
+ info symbol (*($sp+56))&0x7fffffff
+
+you might see something like::
+
+ rl_getc + 36 in section .text
+
+telling you what is located at address 0x528f18
+Now do::
+
+ p/x (*(*$sp+56))&0x7fffffff
+
+This outputs::
+
+ $6 = 0x528ed0
+
+Now do::
+
+ info symbol (*(*$sp+56))&0x7fffffff
+ rl_read_key + 180 in section .text
+
+now do::
+
+ p/x (*(**$sp+56))&0x7fffffff
+
+& so on.
+
+Disassembling instructions without debug info
+---------------------------------------------
+gdb typically complains if there is a lack of debugging
+symbols in the disassemble command with
+"No function contains specified address." To get around
+this do::
+
+ x/<number lines to disassemble>xi <address>
+
+e.g.::
+
+ x/20xi 0x400730
+
+
+
+Note:
+ Remember gdb has history just like bash you don't need to retype the
+ whole line just use the up & down arrows.
+
+
+
+For more info
+-------------
+From your linuxbox do::
+
+ man gdb
+
+or::
+
+ info gdb.
+
+core dumps
+----------
+
+What a core dump ?
+^^^^^^^^^^^^^^^^^^
+
+A core dump is a file generated by the kernel (if allowed) which contains the
+registers and all active pages of the program which has crashed.
+
+From this file gdb will allow you to look at the registers, stack trace and
+memory of the program as if it just crashed on your system. It is usually
+called core and created in the current working directory.
+
+This is very useful in that a customer can mail a core dump to a technical
+support department and the technical support department can reconstruct what
+happened. Provided they have an identical copy of this program with debugging
+symbols compiled in and the source base of this build is available.
+
+In short it is far more useful than something like a crash log could ever hope
+to be.
+
+Why have I never seen one ?
+^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+Probably because you haven't used the command::
+
+ ulimit -c unlimited in bash
+
+to allow core dumps, now do::
+
+ ulimit -a
+
+to verify that the limit was accepted.
+
+A sample core dump
+ To create this I'm going to do::
+
+ ulimit -c unlimited
+ gdb
+
+to launch gdb (my victim app. ) now be bad & do the following from another
+telnet/xterm session to the same machine::
+
+ ps -aux | grep gdb
+ kill -SIGSEGV <gdb's pid>
+
+or alternatively use `killall -SIGSEGV gdb` if you have the killall command.
+
+Now look at the core dump::
+
+ ./gdb core
+
+Displays the following::

+
+LDD
+===
+This is a program which lists the shared libraries which a library needs,
+Note you also get the relocations of the shared library text segments which
+help when using objdump --source.
+
+e.g.::
+
+ ldd ./gdb
+
+outputs::
+
+ libncurses.so.4 => /usr/lib/libncurses.so.4 (0x40018000)
+ libm.so.6 => /lib/libm.so.6 (0x4005e000)
+ libc.so.6 => /lib/libc.so.6 (0x40084000)
+ /lib/ld-linux.so.2 => /lib/ld-linux.so.2 (0x40000000)
+
+
+Debugging shared libraries
+==========================
+Most programs use shared libraries, however it can be very painful
+when you single step instruction into a function like printf for the
+first time & you end up in functions like _dl_runtime_resolve this is
+the ld.so doing lazy binding, lazy binding is a concept in ELF where
+shared library functions are not loaded into memory unless they are
+actually used, great for saving memory but a pain to debug.
+
+To get around this either relink the program -static or exit gdb type
+export LD_BIND_NOW=true this will stop lazy binding & restart the gdb'ing
+the program in question.
+
+
+
+Debugging modules
+=================
+As modules are dynamically loaded into the kernel their address can be
+anywhere to get around this use the -m option with insmod to emit a load
+map which can be piped into a file if required.
+
+The proc file system
+====================
+What is it ?.
+It is a filesystem created by the kernel with files which are created on demand
+by the kernel if read, or can be used to modify kernel parameters,
+it is a powerful concept.
+
+e.g.::
+
+ cat /proc/sys/net/ipv4/ip_forward
+
+On my machine outputs::
+
+ 0
+
+telling me ip_forwarding is not on to switch it on I can do::
+
+ echo 1 > /proc/sys/net/ipv4/ip_forward
+
+cat it again::
+
+ cat /proc/sys/net/ipv4/ip_forward
+
+On my machine now outputs::
+
+ 1
+
+IP forwarding is on.
+
+There is a lot of useful info in here best found by going in and having a look
+around, so I'll take you through some entries I consider important.
+
+All the processes running on the machine have their own entry defined by
+/proc/<pid>
+
+So lets have a look at the init process::
+
+ cd /proc/1
+ cat cmdline
+
+emits::
+
+ init [2]
+
+::
+
+ cd /proc/1/fd
+
+This contains numerical entries of all the open files,
+some of these you can cat e.g. stdout (2)::
+
+ cat /proc/29/maps
+
+on my machine emits::
+
+ 00400000-00478000 r-xp 00000000 5f:00 4103 /bin/bash
+ 00478000-0047e000 rw-p 00077000 5f:00 4103 /bin/bash

+ 7fffd000-80000000 rwxp ffffe000 00:00 0
+
+
+Showing us the shared libraries init uses where they are in memory
+& memory access permissions for each virtual memory area.
+
+/proc/1/cwd is a softlink to the current working directory.
+
+/proc/1/root is the root of the filesystem for this process.
+
+/proc/1/mem is the current running processes memory which you
+can read & write to like a file.
+
+strace uses this sometimes as it is a bit faster than the
+rather inefficient ptrace interface for peeking at DATA.

+
+Some driver debugging techniques
+================================
+debug feature
+-------------
+Some of our drivers now support a "debug feature" in
+/proc/s390dbf see s390dbf.txt in the linux/Documentation directory
+for more info.
+
+e.g.
+to switch on the lcs "debug feature"::
+
+ echo 5 > /proc/s390dbf/lcs/level
+
+& then after the error occurred::
+
+ cat /proc/s390dbf/lcs/sprintf >/logfile
+
+the logfile now contains some information which may help
+tech support resolve a problem in the field.
+
+
+
+high level debugging network drivers
+------------------------------------
+ifconfig is a quite useful command
+it gives the current state of network drivers.
+
+If you suspect your network device driver is dead
+one way to check is type::
+
+ ifconfig <network device>
+
+e.g. tr0
+
+You should see something like::
+
+ ifconfig tr0
+ tr0 Link encap:16/4 Mbps Token Ring (New) HWaddr 00:04:AC:20:8E:48
+ inet addr:9.164.185.132 Bcast:9.164.191.255 Mask:255.255.224.0
+ UP BROADCAST RUNNING MULTICAST MTU:2000 Metric:1
+ RX packets:246134 errors:0 dropped:0 overruns:0 frame:0
+ TX packets:5 errors:0 dropped:0 overruns:0 carrier:0
+ collisions:0 txqueuelen:100
+
+if the device doesn't say up
+try::
+
+ /etc/rc.d/init.d/network start
+
+( this starts the network stack & hopefully calls ifconfig tr0 up ).
+ifconfig looks at the output of /proc/net/dev and presents it in a more
+presentable form.
+
+Now ping the device from a machine in the same subnet.
+
+if the RX packets count & TX packets counts don't increment you probably
+have problems.
+
+next::
+
+ cat /proc/net/arp
+
+Do you see any hardware addresses in the cache if not you may have problems.
+Next try::
+
+ ping -c 5 <broadcast_addr>
+
+i.e. the Bcast field above in the output of
+ifconfig. Do you see any replies from machines other than the local machine
+if not you may have problems. also if the TX packets count in ifconfig

+
+chandev
+-------
+There is a new device layer for channel devices, some
+drivers e.g. lcs are registered with this layer.
+
+If the device uses the channel device layer you'll be
+able to find what interrupts it uses & the current state
+of the device.
+
+See the manpage chandev.8 &type cat /proc/chandev for more info.
+
+
+SysRq
+=====
+This is now supported by linux for s/390 & z/Architecture.
+
+To enable it do compile the kernel with::
+
+ Kernel Hacking -> Magic SysRq Key Enabled
+
+Then::
+
+ echo "1" > /proc/sys/kernel/sysrq
+
+also type::
+
+ echo "8" >/proc/sys/kernel/printk
+
+To make printk output go to console.
+
+On 390 all commands are prefixed with::
+
+ ^-
+
+e.g.::
+
+ ^-t will show tasks.
+ ^-? or some unknown command will display help.
+
+The sysrq key reading is very picky ( I have to type the keys in an
+xterm session & paste them into the x3270 console )
+& it may be wise to predefine the keys as described in the VM hints above
+
+This is particularly useful for syncing disks unmounting & rebooting
+if the machine gets partially hung.

+Read Documentation/admin-guide/sysrq.rst for more info

+S390 Debug Feature
+==================
+
+files:
+ - arch/s390/kernel/debug.c
+ - arch/s390/include/asm/debug.h
+
+Description:
+------------
+The goal of this feature is to provide a kernel debug logging API
+where log records can be stored efficiently in memory, where each component
+(e.g. device drivers) can have one separate debug log.
+One purpose of this is to inspect the debug logs after a production system crash
+in order to analyze the reason for the crash.
+
+If the system still runs but only a subcomponent which uses dbf fails,
+it is possible to look at the debug logs on a live system via the Linux
+debugfs filesystem.
+
+The debug feature may also very useful for kernel and driver development.
+
+Design:
+-------
+Kernel components (e.g. device drivers) can register themselves at the debug
+feature with the function call :c:func:`debug_register()`.
+This function initializes a
+debug log for the caller. For each debug log exists a number of debug areas
+where exactly one is active at one time. Each debug area consists of contiguous
+pages in memory. In the debug areas there are stored debug entries (log records)
+which are written by event- and exception-calls.
+
+An event-call writes the specified debug entry to the active debug
+area and updates the log pointer for the active area. If the end
+of the active debug area is reached, a wrap around is done (ring buffer)
+and the next debug entry will be written at the beginning of the active
+debug area.
+
+An exception-call writes the specified debug entry to the log and
+switches to the next debug area. This is done in order to be sure
+that the records which describe the origin of the exception are not
+overwritten when a wrap around for the current area occurs.
+
+The debug areas themselves are also ordered in form of a ring buffer.
+When an exception is thrown in the last debug area, the following debug
+entries are then written again in the very first area.
+
+There are four versions for the event- and exception-calls: One for
+logging raw data, one for text, one for numbers (unsigned int and long),
+and one for sprintf-like formatted strings.
+
+Each debug entry contains the following data:
+
+- Timestamp
+- Cpu-Number of calling task
+- Level of debug entry (0...6)
+- Return Address to caller
+- Flag, if entry is an exception or not
+
+The debug logs can be inspected in a live system through entries in
+the debugfs-filesystem. Under the toplevel directory "``s390dbf``" there is
+a directory for each registered component, which is named like the
+corresponding component. The debugfs normally should be mounted to
+``/sys/kernel/debug`` therefore the debug feature can be accessed under
+``/sys/kernel/debug/s390dbf``.
+
+The content of the directories are files which represent different views
+to the debug log. Each component can decide which views should be
+used through registering them with the function :c:func:`debug_register_view()`.
+Predefined views for hex/ascii, sprintf and raw binary data are provided.
+It is also possible to define other views. The content of
+a view can be inspected simply by reading the corresponding debugfs file.
+
+All debug logs have an actual debug level (range from 0 to 6).
+The default level is 3. Event and Exception functions have a :c:data:`level`
+parameter. Only debug entries with a level that is lower or equal
+than the actual level are written to the log. This means, when
+writing events, high priority log entries should have a low level
+value whereas low priority entries should have a high one.
+The actual debug level can be changed with the help of the debugfs-filesystem
+through writing a number string "x" to the ``level`` debugfs file which is
+provided for every debug log. Debugging can be switched off completely
+by using "-" on the ``level`` debugfs file.
+
+Example::
+
+ > echo "-" > /sys/kernel/debug/s390dbf/dasd/level
+
+It is also possible to deactivate the debug feature globally for every
+debug log. You can change the behavior using 2 sysctl parameters in
+``/proc/sys/s390dbf``:
+
+There are currently 2 possible triggers, which stop the debug feature
+globally. The first possibility is to use the ``debug_active`` sysctl. If
+set to 1 the debug feature is running. If ``debug_active`` is set to 0 the
+debug feature is turned off.
+
+The second trigger which stops the debug feature is a kernel oops.
+That prevents the debug feature from overwriting debug information that
+happened before the oops. After an oops you can reactivate the debug feature
+by piping 1 to ``/proc/sys/s390dbf/debug_active``. Nevertheless, it's not
+suggested to use an oopsed kernel in a production environment.
+
+If you want to disallow the deactivation of the debug feature, you can use
+the ``debug_stoppable`` sysctl. If you set ``debug_stoppable`` to 0 the debug
+feature cannot be stopped. If the debug feature is already stopped, it
+will stay deactivated.

+
+Changing the debug level
+------------------------
+
+Example::
+
+
+ > cat /sys/kernel/debug/s390dbf/dasd/level
+ 3
+ > echo "5" > /sys/kernel/debug/s390dbf/dasd/level
+ > cat /sys/kernel/debug/s390dbf/dasd/level
+ 5
+
+Flushing debug areas
+--------------------
+Debug areas can be flushed with piping the number of the desired
+area (0...n) to the debugfs file "flush". When using "-" all debug areas
+are flushed.
+
+Examples:
+
+1. Flush debug area 0::
+
+ > echo "0" > /sys/kernel/debug/s390dbf/dasd/flush
+
+2. Flush all debug areas::
+
+ > echo "-" > /sys/kernel/debug/s390dbf/dasd/flush
+
+Changing the size of debug areas
+------------------------------------
+It is possible the change the size of debug areas through piping
+the number of pages to the debugfs file "pages". The resize request will
+also flush the debug areas.
+
+Example:
+
+Define 4 pages for the debug areas of debug feature "dasd"::
+
+ > echo "4" > /sys/kernel/debug/s390dbf/dasd/pages
+
+Stopping the debug feature
+--------------------------
+Example:
+
+1. Check if stopping is allowed::
+
+ > cat /proc/sys/s390dbf/debug_stoppable
+
+2. Stop debug feature::
+
+ > echo 0 > /proc/sys/s390dbf/debug_active
+
+crash Interface
+----------------
+The ``crash`` tool since v5.1.0 has a built-in command
+``s390dbf`` to display all the debug logs or export them to the file system.
+With this tool it is possible
+to investigate the debug logs on a live system and with a memory dump after
+a system crash.
+
+Investigating raw memory
+------------------------
+One last possibility to investigate the debug logs at a live
+system and after a system crash is to look at the raw memory
+under VM or at the Service Element.
+It is possible to find the anchor of the debug-logs through
+the ``debug_area_first`` symbol in the System map. Then one has
+to follow the correct pointers of the data-structures defined
+in debug.h and find the debug-areas in memory.
+Normally modules which use the debug feature will also have
+a global variable with the pointer to the debug-logs. Following
+this pointer it will also be possible to find the debug logs in
+memory.
+
+For this method it is recommended to use '16 * x + 4' byte (x = 0..n)
+for the length of the data field in :c:func:`debug_register()` in
+order to see the debug entries well formatted.
+
+
+Predefined Views
+----------------
+
+There are three predefined views: hex_ascii, raw and sprintf.
+The hex_ascii view shows the data field in hex and ascii representation
+(e.g. ``45 43 4b 44 | ECKD``).
+The raw view returns a bytestream as the debug areas are stored in memory.
+
+The sprintf view formats the debug entries in the same way as the sprintf
+function would do. The sprintf event/exception functions write to the
+debug entry a pointer to the format string (size = sizeof(long))
+and for each vararg a long value. So e.g. for a debug entry with a format
+string plus two varargs one would need to allocate a (3 * sizeof(long))
+byte data area in the debug_register() function.
+
+IMPORTANT:
+ Using "%s" in sprintf event functions is dangerous. You can only
+ use "%s" in the sprintf event functions, if the memory for the passed string
+ is available as long as the debug feature exists. The reason behind this is
+ that due to performance considerations only a pointer to the string is stored
+ in the debug feature. If you log a string that is freed afterwards, you will
+ get an OOPS when inspecting the debug feature, because then the debug feature
+ will access the already freed memory.
+
+NOTE:
+ If using the sprintf view do NOT use other event/exception functions
+ than the sprintf-event and -exception functions.
+
+The format of the hex_ascii and sprintf view is as follows:
+
+- Number of area
+- Timestamp (formatted as seconds and microseconds since 00:00:00 Coordinated
+ Universal Time (UTC), January 1, 1970)
+- level of debug entry
+- Exception flag (* = Exception)
+- Cpu-Number of calling task
+- Return Address to caller
+- data field
+
+The format of the raw view is:
+
+- Header as described in debug.h
+- datafield
+
+A typical line of the hex_ascii view will look like the following (first line
+is only for explanation and will not be displayed when 'cating' the view)::
+
+ area time level exception cpu caller data (hex + ascii)

+
+
+Defining views
+--------------
+
+Views are specified with the 'debug_view' structure. There are defined
+callback functions which are used for reading and writing the debugfs files:
+
+.. code-block:: c
+
+ struct debug_view {
+ char name[DEBUG_MAX_PROCF_LEN];
+ debug_prolog_proc_t* prolog_proc;
+ debug_header_proc_t* header_proc;
+ debug_format_proc_t* format_proc;
+ debug_input_proc_t* input_proc;
+ void* private_data;
+ };
+
+where:
+
+.. code-block:: c
+
+ typedef int (debug_header_proc_t) (debug_info_t* id,
+ struct debug_view* view,
+ int area,
+ debug_entry_t* entry,
+ char* out_buf);
+
+ typedef int (debug_format_proc_t) (debug_info_t* id,
+ struct debug_view* view, char* out_buf,
+ const char* in_buf);
+ typedef int (debug_prolog_proc_t) (debug_info_t* id,
+ struct debug_view* view,
+ char* out_buf);
+ typedef int (debug_input_proc_t) (debug_info_t* id,
+ struct debug_view* view,
+ struct file* file, const char* user_buf,
+ size_t in_buf_size, loff_t* offset);
+
+
+The "private_data" member can be used as pointer to view specific data.
+It is not used by the debug feature itself.
+
+The output when reading a debugfs file is structured like this::
+
+ "prolog_proc output"
+
+ "header_proc output 1" "format_proc output 1"
+ "header_proc output 2" "format_proc output 2"
+ "header_proc output 3" "format_proc output 3"
+ ...
+
+When a view is read from the debugfs, the Debug Feature calls the
+'prolog_proc' once for writing the prolog.
+Then 'header_proc' and 'format_proc' are called for each
+existing debug entry.
+
+The input_proc can be used to implement functionality when it is written to
+the view (e.g. like with ``echo "0" > /sys/kernel/debug/s390dbf/dasd/level``).
+
+For header_proc there can be used the default function
+:c:func:`debug_dflt_header_fn()` which is defined in debug.h.
+and which produces the same header output as the predefined views.
+E.g::
+
+ 00 00964419409:440761 2 - 00 88023ec
+
+In order to see how to use the callback functions check the implementation
+of the default views!
+
+Example:
+
+.. code-block:: c
+
+ #include <asm/debug.h>
+
+ #define UNKNOWNSTR "data: %08x"
+
+ const char* messages[] =
+ {"This error...........\n",
+ "That error...........\n",
+ "Problem..............\n",
+ "Something went wrong.\n",
+ "Everything ok........\n",
+ NULL
+ };
+
+ static int debug_test_format_fn(
+ debug_info_t *id, struct debug_view *view,
+ char *out_buf, const char *in_buf
+ )
+ {
+ int i, rc = 0;
+
+ if (id->buf_size >= 4) {
+ int msg_nr = *((int*)in_buf);
+ if (msg_nr < sizeof(messages) / sizeof(char*) - 1)
+ rc += sprintf(out_buf, "%s", messages[msg_nr]);
+ else
+ rc += sprintf(out_buf, UNKNOWNSTR, msg_nr);
+ }
+ return rc;
+ }
+
+ struct debug_view debug_test_view = {
+ "myview", /* name of view */

-S390 Debug Feature
-==================
-
-files: arch/s390/kernel/debug.c
- arch/s390/include/asm/debug.h
-
-Description:
-------------
-The goal of this feature is to provide a kernel debug logging API
-where log records can be stored efficiently in memory, where each component
-(e.g. device drivers) can have one separate debug log.
-One purpose of this is to inspect the debug logs after a production system crash
-in order to analyze the reason for the crash.
-If the system still runs but only a subcomponent which uses dbf fails,
-it is possible to look at the debug logs on a live system via the Linux
-debugfs filesystem.
-The debug feature may also very useful for kernel and driver development.
-
-Design:
--------
-Kernel components (e.g. device drivers) can register themselves at the debug
-feature with the function call debug_register(). This function initializes a
-debug log for the caller. For each debug log exists a number of debug areas
-where exactly one is active at one time. Each debug area consists of contiguous
-pages in memory. In the debug areas there are stored debug entries (log records)
-which are written by event- and exception-calls.
-
-An event-call writes the specified debug entry to the active debug
-area and updates the log pointer for the active area. If the end
-of the active debug area is reached, a wrap around is done (ring buffer)
-and the next debug entry will be written at the beginning of the active
-debug area.
-
-An exception-call writes the specified debug entry to the log and
-switches to the next debug area. This is done in order to be sure
-that the records which describe the origin of the exception are not
-overwritten when a wrap around for the current area occurs.
-
-The debug areas themselves are also ordered in form of a ring buffer.
-When an exception is thrown in the last debug area, the following debug
-entries are then written again in the very first area.
-
-There are three versions for the event- and exception-calls: One for
-logging raw data, one for text and one for numbers.
-
-Each debug entry contains the following data:
-
-- Timestamp
-- Cpu-Number of calling task
-- Level of debug entry (0...6)
-- Return Address to caller
-- Flag, if entry is an exception or not
-
-The debug logs can be inspected in a live system through entries in
-the debugfs-filesystem. Under the toplevel directory "s390dbf" there is
-a directory for each registered component, which is named like the
-corresponding component. The debugfs normally should be mounted to
-/sys/kernel/debug therefore the debug feature can be accessed under
-/sys/kernel/debug/s390dbf.
-
-The content of the directories are files which represent different views
-to the debug log. Each component can decide which views should be
-used through registering them with the function debug_register_view().
-Predefined views for hex/ascii, sprintf and raw binary data are provided.
-It is also possible to define other views. The content of
-a view can be inspected simply by reading the corresponding debugfs file.
-
-All debug logs have an actual debug level (range from 0 to 6).
-The default level is 3. Event and Exception functions have a 'level'
-parameter. Only debug entries with a level that is lower or equal
-than the actual level are written to the log. This means, when
-writing events, high priority log entries should have a low level
-value whereas low priority entries should have a high one.
-The actual debug level can be changed with the help of the debugfs-filesystem
-through writing a number string "x" to the 'level' debugfs file which is
-provided for every debug log. Debugging can be switched off completely
-by using "-" on the 'level' debugfs file.
-
-Example:
-
-> echo "-" > /sys/kernel/debug/s390dbf/dasd/level
-
-It is also possible to deactivate the debug feature globally for every
-debug log. You can change the behavior using 2 sysctl parameters in
-/proc/sys/s390dbf:
-There are currently 2 possible triggers, which stop the debug feature
-globally. The first possibility is to use the "debug_active" sysctl. If
-set to 1 the debug feature is running. If "debug_active" is set to 0 the
-debug feature is turned off.
-The second trigger which stops the debug feature is a kernel oops.
-That prevents the debug feature from overwriting debug information that
-happened before the oops. After an oops you can reactivate the debug feature
-by piping 1 to /proc/sys/s390dbf/debug_active. Nevertheless, its not
-suggested to use an oopsed kernel in a production environment.
-If you want to disallow the deactivation of the debug feature, you can use
-the "debug_stoppable" sysctl. If you set "debug_stoppable" to 0 the debug
-feature cannot be stopped. If the debug feature is already stopped, it
-will stay deactivated.

-Changing the debug level
-------------------------
-
-Example:
-
-
-> cat /sys/kernel/debug/s390dbf/dasd/level
-3
-> echo "5" > /sys/kernel/debug/s390dbf/dasd/level
-> cat /sys/kernel/debug/s390dbf/dasd/level
-5
-
-Flushing debug areas
---------------------
-Debug areas can be flushed with piping the number of the desired
-area (0...n) to the debugfs file "flush". When using "-" all debug areas
-are flushed.
-
-Examples:
-
-1. Flush debug area 0:
-> echo "0" > /sys/kernel/debug/s390dbf/dasd/flush
-
-2. Flush all debug areas:
-> echo "-" > /sys/kernel/debug/s390dbf/dasd/flush
-
-Changing the size of debug areas
-------------------------------------
-It is possible the change the size of debug areas through piping
-the number of pages to the debugfs file "pages". The resize request will
-also flush the debug areas.
-
-Example:
-
-Define 4 pages for the debug areas of debug feature "dasd":
-> echo "4" > /sys/kernel/debug/s390dbf/dasd/pages
-
-Stooping the debug feature
---------------------------
-Example:
-
-1. Check if stopping is allowed
-> cat /proc/sys/s390dbf/debug_stoppable
-2. Stop debug feature
-> echo 0 > /proc/sys/s390dbf/debug_active
-
-lcrash Interface
-----------------
-It is planned that the dump analysis tool lcrash gets an additional command
-'s390dbf' to display all the debug logs. With this tool it will be possible
-to investigate the debug logs on a live system and with a memory dump after
-a system crash.
-
-Investigating raw memory
-------------------------
-One last possibility to investigate the debug logs at a live
-system and after a system crash is to look at the raw memory
-under VM or at the Service Element.
-It is possible to find the anker of the debug-logs through
-the 'debug_area_first' symbol in the System map. Then one has
-to follow the correct pointers of the data-structures defined
-in debug.h and find the debug-areas in memory.
-Normally modules which use the debug feature will also have
-a global variable with the pointer to the debug-logs. Following
-this pointer it will also be possible to find the debug logs in
-memory.
-
-For this method it is recommended to use '16 * x + 4' byte (x = 0..n)
-for the length of the data field in debug_register() in
-order to see the debug entries well formatted.
-
-
-Predefined Views
-----------------
-
-There are three predefined views: hex_ascii, raw and sprintf.
-The hex_ascii view shows the data field in hex and ascii representation
-(e.g. '45 43 4b 44 | ECKD').
-The raw view returns a bytestream as the debug areas are stored in memory.
-
-The sprintf view formats the debug entries in the same way as the sprintf
-function would do. The sprintf event/exception functions write to the
-debug entry a pointer to the format string (size = sizeof(long))
-and for each vararg a long value. So e.g. for a debug entry with a format
-string plus two varargs one would need to allocate a (3 * sizeof(long))
-byte data area in the debug_register() function.
-
-IMPORTANT: Using "%s" in sprintf event functions is dangerous. You can only
-use "%s" in the sprintf event functions, if the memory for the passed string is
-available as long as the debug feature exists. The reason behind this is that
-due to performance considerations only a pointer to the string is stored in
-the debug feature. If you log a string that is freed afterwards, you will get
-an OOPS when inspecting the debug feature, because then the debug feature will
-access the already freed memory.
-
-NOTE: If using the sprintf view do NOT use other event/exception functions
-than the sprintf-event and -exception functions.
-
-The format of the hex_ascii and sprintf view is as follows:
-- Number of area
-- Timestamp (formatted as seconds and microseconds since 00:00:00 Coordinated
- Universal Time (UTC), January 1, 1970)
-- level of debug entry
-- Exception flag (* = Exception)
-- Cpu-Number of calling task
-- Return Address to caller
-- data field
-
-The format of the raw view is:
-- Header as described in debug.h
-- datafield
-
-A typical line of the hex_ascii view will look like the following (first line
-is only for explanation and will not be displayed when 'cating' the view):
-
-area time level exception cpu caller data (hex + ascii)

-Defining views
---------------
-
-Views are specified with the 'debug_view' structure. There are defined
-callback functions which are used for reading and writing the debugfs files:
-
-struct debug_view {
- char name[DEBUG_MAX_PROCF_LEN];
- debug_prolog_proc_t* prolog_proc;
- debug_header_proc_t* header_proc;
- debug_format_proc_t* format_proc;
- debug_input_proc_t* input_proc;
- void* private_data;
-};
-
-where
-
-typedef int (debug_header_proc_t) (debug_info_t* id,
- struct debug_view* view,
- int area,
- debug_entry_t* entry,
- char* out_buf);
-
-typedef int (debug_format_proc_t) (debug_info_t* id,
- struct debug_view* view, char* out_buf,
- const char* in_buf);
-typedef int (debug_prolog_proc_t) (debug_info_t* id,
- struct debug_view* view,
- char* out_buf);
-typedef int (debug_input_proc_t) (debug_info_t* id,
- struct debug_view* view,
- struct file* file, const char* user_buf,
- size_t in_buf_size, loff_t* offset);
-
-
-The "private_data" member can be used as pointer to view specific data.
-It is not used by the debug feature itself.
-
-The output when reading a debugfs file is structured like this:
-
-"prolog_proc output"
-
-"header_proc output 1" "format_proc output 1"
-"header_proc output 2" "format_proc output 2"
-"header_proc output 3" "format_proc output 3"
-...
-
-When a view is read from the debugfs, the Debug Feature calls the
-'prolog_proc' once for writing the prolog.
-Then 'header_proc' and 'format_proc' are called for each
-existing debug entry.
-
-The input_proc can be used to implement functionality when it is written to
-the view (e.g. like with 'echo "0" > /sys/kernel/debug/s390dbf/dasd/level).
-
-For header_proc there can be used the default function
-debug_dflt_header_fn() which is defined in debug.h.
-and which produces the same header output as the predefined views.
-E.g:
-00 00964419409:440761 2 - 00 88023ec
-
-In order to see how to use the callback functions check the implementation
-of the default views!
-

-
-#include <asm/debug.h>
-
-#define UNKNOWNSTR "data: %08x"
-
-const char* messages[] =
-{"This error...........\n",
- "That error...........\n",
- "Problem..............\n",
- "Something went wrong.\n",
- "Everything ok........\n",
- NULL
-};
-
-static int debug_test_format_fn(
- debug_info_t * id, struct debug_view *view,
- char *out_buf, const char *in_buf
-)
-{
- int i, rc = 0;
-
- if(id->buf_size >= 4) {
- int msg_nr = *((int*)in_buf);
- if(msg_nr < sizeof(messages)/sizeof(char*) - 1)
- rc += sprintf(out_buf, "%s", messages[msg_nr]);
- else
- rc += sprintf(out_buf, UNKNOWNSTR, msg_nr);
- }
- out:
- return rc;
-}
-
-struct debug_view debug_test_view = {
- "myview", /* name of view */
- NULL, /* no prolog */
- &debug_dflt_header_fn, /* default header for each entry */
- &debug_test_format_fn, /* our own format function */
- NULL, /* no input function */
- NULL /* no private data */
-};

Requirements
============
-A host with a USB port. Ideally, either a UHCI (Intel) or OHCI
-(Compaq and others) hardware port should work.
+A host with a USB port running a Linux kernel with RIO 500 support enabled.
-A Linux development kernel (2.3.x) with USB support enabled or a
-backported version to linux-2.2.x. See http://www.linux-usb.org for
-more information on accomplishing this.
+The driver is a module called rio500, which should be automatically loaded
+as you plug in your device. If that fails you can manually load it with
-A Linux kernel with RIO 500 support enabled.
+ modprobe rio500
-'lspci' which is only needed to determine the type of USB hardware
-available in your machine.
-
-Configuration
-
-Using `lspci -v`, determine the type of USB hardware available.
-
- If you see something like::
-
- USB Controller: ......
- Flags: .....
- I/O ports at ....
-
- Then you have a UHCI based controller.
-
- If you see something like::
-
- USB Controller: .....
- Flags: ....
- Memory at .....
-
- Then you have a OHCI based controller.
-
-Using `make menuconfig` or your preferred method for configuring the
-kernel, select 'Support for USB', 'OHCI/UHCI' depending on your
-hardware (determined from the steps above), 'USB Diamond Rio500 support', and
-'Preliminary USB device filesystem'. Compile and install the modules
-(you may need to execute `depmod -a` to update the module
-dependencies).
-
-Add a device for the USB rio500::
+Udev should automatically create a device node as soon as plug in your device.
+If that fails, you can manually add a device for the USB rio500::
mknod /dev/usb/rio500 c 180 64
-Set appropriate permissions for /dev/usb/rio500 (don't forget about
-group and world permissions). Both read and write permissions are
+In that case, set appropriate permissions for /dev/usb/rio500 (don't forget
+about group and world permissions). Both read and write permissions are
required for proper operation.
-Load the appropriate modules (if compiled as modules):
-
- OHCI::
-
- modprobe usbcore
- modprobe usb-ohci
- modprobe rio500
-
- UHCI::
-
- modprobe usbcore
- modprobe usb-uhci (or uhci)
- modprobe rio500
-
That's it. The Rio500 Utils at: http://rio500.sourceforge.net should
be able to access the rio500.
+Limits
+======
+
+You can use only a single rio500 device at a time with your computer.
