------------------
From: Nick Piggin <npiggin@suse.de>
commit 3a4c6800f31ea8395628af5e7e490270ee5d0585 upstream.
A bug was introduced into write_cache_pages cyclic writeout by commit
31a12666d8f0c22235297e1c1575f82061480029 ("mm: write_cache_pages cyclic
fix"). The intention (and comments) is that we should cycle back and
look for more dirty pages at the beginning of the file if there is no
more work to be done.
But the !done condition was dropped from the test. This means that any
time the page writeout loop breaks (eg. due to nr_to_write == 0), we
will set index to 0, then goto again. This will set done_index to
index, then find done is set, so will proceed to the end of the
function. When updating mapping->writeback_index for cyclic writeout,
we now use done_index == 0, so we're always cycling back to 0.
This seemed to be causing random mmap writes (slapadd and iozone) to
start writing more pages from the LRU and writeout would slowdown, and
caused bugzilla entry
http://bugzilla.kernel.org/show_bug.cgi?id=12604
about Berkeley DB slowing down dramatically.
With this patch, iozone random write performance is increased nearly
5x on my system (iozone -B -r 4k -s 64k -s 512m -s 1200m on ext2).

------------------
From: Randy Dunlap <randy.dunlap@oracle.com>
commit b4870bc5ee8c7a37541a3eb1208b5c76c13a078a upstream.
Fix kernel-doc processing of SYSCALL wrappers.
The SYSCALL wrapper patches played havoc with kernel-doc for
syscalls. Syscalls that were scanned for DocBook processing
reported warnings like this one, for sys_tgkill:
Warning(kernel/signal.c:2285): No description found for parameter 'tgkill'
Warning(kernel/signal.c:2285): No description found for parameter 'pid_t'
Warning(kernel/signal.c:2285): No description found for parameter 'int'
because the macro parameters all "look like" function parameters,
although they are not:
/**
* sys_tgkill - send signal to one specific thread
* @tgid: the thread group ID of the thread
* @pid: the PID of the thread
* @sig: signal to be sent
*
* This syscall also checks the @tgid and returns -ESRCH even if the PID
* exists but it's not belonging to the target process anymore. This
* method solves the problem of threads exiting and PIDs getting reused.
*/
SYSCALL_DEFINE3(tgkill, pid_t, tgid, pid_t, pid, int, sig)
{
...
This patch special-cases the handling SYSCALL_DEFINE* function
prototypes by expanding them to
long sys_foobar(type1 arg1, type1 arg2, ...)

------------------
From: J. Bruce Fields <bfields@citi.umich.edu>
commit 9d9b87c1218be78ddecbc85ec3bb91c79c1d56ab upstream.
If a client requests a blocking lock, is denied, then requests it again,
then here in nlmsvc_lock() we will call vfs_lock_file() without FL_SLEEP
set, because we've already queued a block and don't need the locks code
to do it again.
But that means vfs_lock_file() will return -EAGAIN instead of
FILE_LOCK_DENIED. So we still need to translate that -EAGAIN return
into a nlm_lck_blocked error in this case, and put ourselves back on
lockd's block list.
The bug was introduced by bde74e4bc64415b1 "locks: add special return
value for asynchronous locks".
Thanks to Frank van Maarseveen for the report; his original test
case was essentially
for i in `seq 30`; do flock /nfsmount/foo sleep 10 & done

------------------
From: Paul Clements <paul.clements@steeleye.com>
commit 4d48a542b42747c36a5937447d9c3de7c897ea50 upstream.
Fix a problem that causes I/O to a disconnected (or partially initialized)
nbd device to hang indefinitely. To reproduce:
# ioctl NBD_SET_SIZE_BLOCKS /dev/nbd23 514048
# dd if=/dev/nbd23 of=/dev/null bs=4096 count=1
...hangs...
This can also occur when an nbd device loses its nbd-client/server
connection. Although we clear the queue of any outstanding I/Os after the
client/server connection fails, any additional I/Os that get queued later
will hang.
This bug may also be the problem reported in this bug report:
http://bugzilla.kernel.org/show_bug.cgi?id=12277
Testing would need to be performed to determine if the two issues are the
same.
This problem was introduced by the new request handling thread code ("NBD:
allow nbd to be used locally", 3/2008), which entered into mainline around
2.6.25.
The fix, which is fairly simple, is to restore the check for lo->sock
being NULL in do_nbd_request. This causes I/O to an uninitialized nbd to
immediately fail with an I/O error, as it did prior to the introduction of
this bug.

Since VSX support was added, we now have two sizes of ucontext_t;
the older, smaller size without the extra VSX state, and the new
larger size with the extra VSX state. A program using the
sys_swapcontext system call and supplying smaller ucontext_t
structures will currently get an EINVAL error if the task has
used VSX (e.g. because of calling library code that uses VSX) and
the old_ctx argument is non-NULL (i.e. the program is asking for
its current context to be saved). Thus the program will start
getting EINVAL errors on calls that previously worked.
This commit changes this behaviour so that we don't send an EINVAL in
this case. It will now return the smaller context but the VSX MSR bit
will always be cleared to indicate that the ucontext_t doesn't include
the extra VSX state, even if the task has executed VSX instructions.
Both 32 and 64 bit cases are updated.
[paulus@samba.org - also fix some access_ok() and get_user() calls]
Thanks to Ben Herrenschmidt for noticing this problem.

From: Kumar Gala <galak@kernel.crashing.org>
commit 6c24b17453c8dc444a746e45b8a404498fc9fcf7 upstream.
Fixed v_mapped_by_tlbcam() and p_mapped_by_tlbcam() to use phys_addr_t
instead of unsigned long. In 36-bit physical mode we really need these
functions to deal with phys_addr_t when trying to match a physical
address or when returning one.

2.6.27-stable review patch. If anyone has any objections, please let us know.
------------------
From: Heiko Carstens <heiko.carstens@de.ibm.com>
commit 6c5979631b4b03c9288776562c18036765e398c1 upstream.
With the new system call defines we get this on uml:
arch/um/sys-i386/built-in.o: In function `sys_call_table':
(.rodata+0x308): undefined reference to `sys_sigprocmask'
Reason for this is that uml passes the preprocessor option
-Dsigprocmask=kernel_sigprocmask to gcc when compiling the kernel.
This causes SYSCALL_DEFINE3(sigprocmask, ...) to be expanded to
SYSCALL_DEFINEx(3, kernel_sigprocmask, ...) and finally to a system
call named sys_kernel_sigprocmask. However sys_sigprocmask is missing
because of this.
To avoid macro expansion for the system call name just concatenate the
name at first define instead of carrying it through severel levels.
This was pointed out by Al Viro.

commit dcf6a79dda5cc2a2bec183e50d829030c0972aaa upstream.
Commit 05fe478dd04e02fa230c305ab9b5616669821dd3 introduced some
@wbc->nr_to_write breakage.
It made the following changes:
1. Decrement wbc->nr_to_write instead of nr_to_write
2. Decrement wbc->nr_to_write _only_ if wbc->sync_mode == WB_SYNC_NONE
3. If synced nr_to_write pages, stop only if if wbc->sync_mode ==
WB_SYNC_NONE, otherwise keep going.
However, according to the commit message, the intention was to only make
change 3. Change 1 is a bug. Change 2 does not seem to be necessary,
and it breaks UBIFS expectations, so if needed, it should be done
separately later. And change 2 does not seem to be documented in the
commit message.
This patch does the following:
1. Undo changes 1 and 2
2. Add a comment explaining change 3 (it very useful to have comments
in _code_, not only in the commit).

Commit dcf6a79dda5cc2a2bec183e50d829030c0972aaa ("write-back: fix
nr_to_write counter") fixed nr_to_write counter, but didn't set the break
condition properly.
If nr_to_write == 0 after being decremented it will loop one more time
before setting done = 1 and breaking the loop.

From: Alok Kataria <akataria@vmware.com>
commit 55a8ba4b7f76bebd7e8ce3f74c04b140627a1bad upstream.
Commit 6194ba6ff6ccf8d5c54c857600843c67aa82c407 ("x86: don't special-case
pmd allocations as much") made changes to the way we handle pmd allocations,
and while doing that it dropped a call to paravirt_release_pd on the
pgd page from the pgd_dtor code path.
As a result of this missing release, the hypervisor is now unaware of the
pgd page being freed, and as a result it ends up tracking this page as a
page table page.
After this the guest may start using the same page for other purposes, and
depending on what use the page is put to, it may result in various performance
and/or functional issues ( hangs, reboots).
Since this release is only required for VMI, I now release the pgd page from
the (vmi)_pgd_free hook.

in the sourceforge zd1211 mailing list on this addition. This product ID

earlier) and it probably should have been added earlier.

[ Upstream commit 9c5ff5f75d0d0a1c7928ecfae3f38418b51a88e3 ]
crc32c algorithm provides a byteswaped result. On little-endian
arches, the result ends up in big-endian/network byte order.
On big-endinan arches, the result ends up in little-endian
order and needs to be byte swapped again. Thus calling cpu_to_le32
gives the right output.

(sctp: Start T3-RTX timer when fast retransmitting lowest TSN)
introduced a regression where it was possible to forcibly
restart the sctp retransmit timer at the transmission of any
new chunk. This resulted in much longer timeout times and
sometimes hung sctp connections.

From: Vlad Yasevich <vladislav.yasevich@hp.com>
[ Upstream commit 759af00ebef858015eb68876ac1f383bcb6a1774 ]
Recent changes to the retransmit code exposed a long standing
bug where it was possible for a chunk to be time stamped
after the retransmit timer was reset. This caused a rare
situation where the retrnamist timer has expired, but
nothing was marked for retrnasmission because all of
timesamps on data were less then 1 rto ago. As result,
the timer was never restarted since nothing was retransmitted,
and this resulted in a hung association that did couldn't
complete the data transfer. The solution is to timestamp
the chunk when it's added to the packet for transmission
purposes. After the packet is trsnmitted the rtx timer
is restarted. This guarantees that when the timer expires,
there will be data to retransmit.

From: Clément Lecigne <clement.lecigne@netasq.com>
[ Upstream commit df0bca049d01c0ee94afb7cd5dfd959541e6c8da ]
In function sock_getsockopt() located in net/core/sock.c, optval v.val
is not correctly initialized and directly returned in userland in case
we have SO_BSDCOMPAT option set.
This dummy code should trigger the bug:
int main(void)
{
unsigned char buf[4] = { 0, 0, 0, 0 };
int len;
int sock;
sock = socket(33, 2, 2);
getsockopt(sock, 1, SO_BSDCOMPAT, &buf, &len);
printf("%x%x%x%x\n", buf[0], buf[1], buf[2], buf[3]);
close(sock);
}
Here is a patch that fix this bug by initalizing v.val just after its
declaration.

packet_lookup_frames() fails to get user frame if current frame header
status contains extra flags.
This is due to the wrong assumption on the operators precedence during
frame status tests.
Fixed by forcing the right operators precedence order with explicit brackets.

[ Upstream commit 71822faa3bc0af5dbf5e333a2d085f1ed7cd809f ]
From: Ilkka Virta <itvirta@iki.fi>
In the lockup situation the driver seems to go off in an eternal storm
of interrupts right after calling request_irq(). It doesn't actually
do anything interesting in the interrupt handler. Since connecting the link
afterwards works, something later in initialization must fix this.
Looking at gem_do_start() and gem_open(), it seems that the only thing
done while opening the device after the request_irq(), is a call to
napi_enable().
I don't know what the ordering requirements are for the
initialization, but I boldly tried to move the napi_enable() call
inside gem_do_start() before the link state is checked and interrupts
subsequently enabled, and it seems to work for me. Doesn't even break
anything too obvious...

From: Alex Williamson <alex.williamson@hp.com>
[ Upstream commit cfbf84fcbcda98bb91ada683a8dc8e6901a83ebd ]
Tap devices can make use of a small MAC filter set via the
TUNSETTXFILTER ioctl. The filter has a set of exact matches
plus a hash for imperfect filtering of additional multicast
addresses. The current code is unbalanced, adding unicast
addresses to the multicast hash, but only checking the hash
against multicast addresses. This results in the filter
dropping unicast addresses that overflow the exact filter.
The fix is simply to disable the filter by leaving count set
to zero if we find non-multicast addresses after the exact
match table is filled.

The UDP header pointer assignment must happen after calling
pskb_may_pull(). As pskb_may_pull() can potentially alter the SKB
buffer.
This was exposted by running multicast traffic through the NIU driver,
as it won't prepull the protocol headers into the linear area on
receive.

802.1Q expanded the maximum ethernet frame size by 4 bytes for the
VLAN tag. We're not taking this into account in virtio_net, which
means the buffers we provide to the backend in the virtqueue RX ring
aren't big enough to hold a full MTU VLAN packet. For QEMU/KVM,
this results in the backend exiting with a packet truncation error.

[ Upstream commit 95e3b24cfb4ec0479d2c42f7a1780d68063a542a ]
The frag_list handling was broken in skb_seq_read:
1) We didn't add the stepped offset when looking at the head
are of fragments other than the first.
2) We didn't take the stepped offset away when setting the data
pointer in the head area.
3) The frag index wasn't reset.
This patch fixes both issues.

------------------
From: Shyam Iyer <shyam_iyer@dell.com>
[ Upstream commit 71b3346d182355f19509fadb8fe45114a35cc499 ]
It oopsd for me in skb_seq_read. addr2line said it was
linux-2.6/net/core/skbuff.c:2228, which is this line:
while (st->frag_idx < skb_shinfo(st->cur_skb)->nr_frags) {
I added some printks in there and it looks like we hit this:
} else if (st->root_skb == st->cur_skb &&
skb_shinfo(st->root_skb)->frag_list) {
st->cur_skb = skb_shinfo(st->root_skb)->frag_list;
st->frag_idx = 0;
goto next_skb;
}
Actually I did some testing and added a few printks and found that the
st->cur_skb->data was 0 and hence the ptr used by iscsi_tcp was null.
This caused the kernel panic.
if (abs_offset < block_limit) {
- *data = st->cur_skb->data + abs_offset;
+ *data = st->cur_skb->data + (abs_offset - st->stepped_offset);
I enabled the debug_tcp and with a few printks found that the code did
not go to the next_skb label and could find that the sequence being
followed was this -
It hit this if condition -
if (st->cur_skb->next) {
st->cur_skb = st->cur_skb->next;
st->frag_idx = 0;
goto next_skb;
And so, now the st pointer is shifted to the next skb whereas actually
it should have hit the second else if first since the data is in the
frag_list.
else if (st->root_skb == st->cur_skb &&
skb_shinfo(st->root_skb)->frag_list) {
st->cur_skb = skb_shinfo(st->root_skb)->frag_list;
goto next_skb;
}
Reversing the two conditions the attached patch fixes the issue for me
on top of Herbert's patches.

From: Herbert Xu <herbert@gondor.apana.org.au>
[ Upstream commit 905db44087855e3c1709f538ecdc22fd149cadd8 ]
As the mmap handler gets called under mmap_sem, and we may grab
mmap_sem elsewhere under the socket lock to access user data, we
should avoid grabbing the socket lock in the mmap handler.
Since the only thing we care about in the mmap handler is for
pg_vec* to be invariant, i.e., to exclude packet_set_ring, we
can achieve this by simply using a new mutex.

------------------
From: Willy Tarreau <w@1wt.eu>
[ Upstream commit 33966dd0e2f68f26943cd9ee93ec6abbc6547a8e ]
As spotted by Willy Tarreau, current splice() from tcp socket to pipe is not
optimal. It processes at most one segment per call.
This results in low performance and very high overhead due to syscall rate
when splicing from interfaces which do not support LRO.
Willy provided a patch inside tcp_splice_read(), but a better fix
is to let tcp_read_sock() process as many segments as possible, so
that tcp_rcv_space_adjust() and tcp_cleanup_rbuf() are called less
often.
With this change, splice() behaves like tcp_recvmsg(), being able
to consume many skbs in one system call. With typical 1460 bytes
of payload per frame, that means splice(SPLICE_F_NONBLOCK) can return
16*1460 = 23360 bytes.

------------------
From: Dimitris Michailidis <dm@chelsio.com>
[ Upstream commit 9fa5fdf291c9b58b1cb8b4bb2a0ee57efa21d635 ]
tcp_splice_data_recv has two lengths to consider: the len parameter it
gets from tcp_read_sock, which specifies the amount of data in the skb,
and rd_desc->count, which is the amount of data the splice caller still
wants. Currently it passes just the latter to skb_splice_bits, which then
splices min(rd_desc->count, skb->len - offset) bytes.
Most of the time this is fine, except when the skb contains urgent data.
In that case len goes only up to the urgent byte and is less than
skb->len - offset. By ignoring len tcp_splice_data_recv may a) splice
data tcp_read_sock told it not to, b) return to tcp_read_sock a value > len.
Now, tcp_read_sock doesn't handle used > len and leaves the socket in a
bad state (both sk_receive_queue and copied_seq are bad at that point)
resulting in duplicated data and corruption.
Fix by passing min(rd_desc->count, len) to skb_splice_bits.

netfilter: fix tuple inversion for Node information request
Upstream commit: a51f42f3c
The patch fixes a typo in the inverse mapping of Node Information
request. Following draft-ietf-ipngwg-icmp-name-lookups-09, "Querier"
sends a type 139 (ICMPV6_NI_QUERY) packet to "Responder" which answer
with a type 140 (ICMPV6_NI_REPLY) packet.

2.6.27-stable review patch. If anyone has any objections, please let us know.
------------------
From: Torsten Rausche <torsten@rausche.net>
This patch is basically a backport of
commit ee8a1a0a1a5817accd03ced7e7ffde3a4430f485 upstream
which was made after the big HID overhaul in 2.6.28.
Kernel 2.6.27 fails to handle quirks for the aluminum Apple Wireless
Keyboard because it is handled as USB device and not as Bluetooth
device. This patch expands 'hidp_blacklist' to make the kernel handle
the keyboard in the same way as the Apple wireless Mighty Mouse (also a
Bluetooth device).

HID: adjust report descriptor fixup for MS 1028 receiver
[Backport to 2.6.27: cebbert@redhat.com]
Report descriptor fixup for MS 1028 receiver changes also values for
Keyboard and Consumer, which incorrectly trims the range, causing correct
events being thrown away before passing to userspace.
We need to keep the GenDesk usage fixup though, as it reports totally bogus
values about axis.

2.6.27-stable review patch. If anyone has any objections, please let us know.
------------------
From: Tejun Heo <tj@kernel.org>
commit d89293abd95bfd7dd9229087d6c30c1464c5ac83 upstream.
The dev->pio_mode > XFER_PIO_0 test is there to avoid unnecessary
speed down warning messages but it accidentally disabled SATA link spd
down during configuration phase after reset where PIO mode is always
zero.
This patch fixes the problem by moving the test where it belongs.
This makes libata probing sequence behave better when the connection
is flaky at higher link speeds which isn't too uncommon for eSATA
devices.

From: Sergei Shtylyov <sshtylyov@ru.mvista.com>
commit 2999b58b795ad81f10e34bdbbfd2742172f247e4 upstream.
When checking for the CFA feature set support, ata_id_is_cfa() tests bit 2 in
word 82 of the identify data instead the word 83; it also checks the ATA/PI
version support in the word 80 (which the CompactFlash specifications have as
reserved), this having no slightest chance to work on the modern CF cards that
don't have 0x848A in the word 0...

Fix the initial value for input hwport. The old value (-1) may cause
Oops when an realtime MIDI byte is received before the input port is
explicitly given.
Instead, now it's set to the broadcasting as default.
