This prevents them propagating\n directly across user_namespaces boundaries (ie. the KEY_SPEC_*\n flags will only pick from the current user_namespace).\n\n - Make it possible to include the target namespace in which the key\n shall operate in the index_key. This will allow the possibility of\n multiple keys with the same description, but different target\n domains to be held in the same keyring.\n\n keyctl_capabilities() shows KEYCTL_CAPS1_NS_KEY_TAG for this.\n\n - Make it so that keys are implicitly invalidated by removal of a\n domain tag, causing them to be garbage collected.\n\n - Institute a network namespace domain tag that allows keys to be\n differentiated by the network namespace in which they operate. New\n keys that are of a type marked \u0027KEY_TYPE_NET_DOMAIN\u0027 are assigned\n the network domain in force when they are created.\n\n - Make it so that the desired network namespace can be handed down\n into the request_key() mechanism. This allows AFS, NFS, etc. to\n request keys specific to the network namespace of the superblock.\n\n This also means that the keys in the DNS record cache are\n thenceforth namespaced, provided network filesystems pass the\n appropriate network namespace down into dns_query().\n\n For DNS, AFS and NFS are good, whilst CIFS and Ceph are not.

What\n gets hashed could be a component to be run or perhaps log of some\n actions taken just to give couple of coarse examples. In general,\n anything relevant for the boot process that the preboot software does\n gets hashed and a log entry with a specific event type [1].\n\n The main application for this is remote attestation and the reason why\n it is useful is nicely put in the very first section of [1]:\n\n \"Attestation is used to provide information about the platform’s\n state to a challenger. However, PCR contents are difficult to\n interpret; therefore, attestation is typically more useful when\n the PCR contents are accompanied by a measurement log. While not\n trusted on their own, the measurement log contains a richer set of\n information than do the PCR contents. The PCR contents are used to\n provide the validation of the measurement log.\"\n\n Because EFI_TCG2_PROTOCOL.GetEventLog() is not available after calling\n ExitBootServices(), Linux EFI stub copies the event log to a custom\n configuration table. Unfortunately, ExitBootServices() also generates\n events and obviously these events do not get copied to that table.\n Luckily firmware does this for us by providing a configuration table\n identified by EFI_TCG2_FINAL_EVENTS_TABLE_GUID.\n\n This essentially contains necessary changes to provide the full event\n log for the use the user space that is concatenated from these two\n partial event logs [2]\"\n\n[1] https://trustedcomputinggroup.org/resource/pc-client-specific-platform-firmware-profile-specification/\n[2] The final concatenation is done in

well.\n\n - atomic64_t cross-arch type cleanups by Mark Rutland: over the last\n ~10 years of atomic64_t existence the various types used by the\n APIs only had to be self-consistent within each architecture -\n which means they became wildly inconsistent across architectures.\n Mark puts and end to this by reworking all the atomic64\n implementations to use \u0027s64\u0027 as the base type for atomic64_t, and\n to ensure that this type is consistently used for parameters and\n return values in the API, avoiding further problems in this area.\n\n - A large set of small improvements to

Fix a long standing issue with spurious interrupts which was caused\n by the big vector management rework a few years ago. Robert Hodaszi\n provided finally enough debug data and an excellent initial failure\n analysis which allowed to understand the underlying issues.\n\n This contains a change to the core interrupt management code which\n is required to handle this correctly for the APIC/IO_APIC. The core\n changes are NOOPs for most architectures except ARM64. ARM64 is not\n impacted by the change as confirmed by Marc Zyngier.\n\n - Newer systems allow to disable the PIT clock for power saving\n causing panic in the timer interrupt delivery check of the IO/APIC\n when the HPET timer is not enabled either. While the clock could be\n turned on this would cause an endless whack a mole game to chase\n the proper register in each affected chipset.\n\n These systems provide the relevant frequencies for TSC, CPU and the\n local APIC timer via CPUID and/or MSRs, which allows to avoid the\n PIT/HPET based calibration. As the calibration code is the only\n usage of the legacy timers on modern systems and is skipped anyway\n when the frequencies are known already, there is no point in\n setting up the PIT and actually checking for the interrupt delivery\n via IO/APIC.\n\n To achieve this on a wide variety of platforms, the CPUID/MSR based\n frequency readout has been made more robust, which also allowed to\n remove quite some workarounds which turned out to be not longer\n required.

This only \u0027works\u0027 with CONFIG_MATH_EMULATION enabled.\n\nBut on 64bit this cannot work because user space expects SSE to work which\nrequired basic FPU support. MATH_EMULATION does not help because SSE is not\nemulated.\n\nThe command line option `nofxsr\u0027 should also be limited to 32bit because\nFXSR is part of the required flags on 64bit so turning it off is not\npossible.\n\nClearing X86_FEATURE_FPU without emulation enabled will not work anyway and\nhang in fpu__init_system_early_generic() before the console is enabled.\n\nSetting additioal dependencies, ensures that the CPU still boots on a\nmodern CPU. Otherwise, dropping FPU will leave FXSR enabled causing the\nkernel to crash early in fpu__init_system_mxcsr().\n\nWith XSAVE support it will crash in fpu__init_cpu_xstate(). The problem is\nthat xsetbv() with XMM set and SSE cleared is not allowed. That means\nXSAVE has to be disabled. The XSAVE support is disabled in\nfpu__init_system_xstate_size_legacy() but it is too late. It can be\nremoved, it has been added in commit\n\n 1f999ab5a1360 (\"x86, xsave: Disable xsave in i387 emulation mode\")\n\nto use `no387\u0027 on a CPU with XSAVE support.\n\nAll this happens before console output.\n\nAfter hat, the next possible crash is in RAID6 detect code because MMX\nremained enabled. With a 3DNOW enabled config it will explode in memcpy()\nfor instance due to kernel_fpu_begin() but this is unconditionally enabled.\n\nThis is enough to boot a Debian Wheezy on a 32bit qemu \"host\" CPU which\nsupports everything up to XSAVES, AVX2 without 3DNOW. Later, Debian\nincreased the minimum requirements to i686 which means it does not boot\nuserland atleast due to CMOV.\n\nAfter masking the additional features it still keeps SSE4A and 3DNOW*\nenabled (if present on the host) but those are unused in the kernel.\n\nRestrict `no387\u0027 and `nofxsr\u0027 otions to 32bit only.

If a malicious\nunprivileged child uses PTRACE_TRACEME and the parent is privileged, and\nat a later point, the parent process becomes attacker-controlled\n(because it drops privileges and calls execve()), the attacker ends up\nwith control over two processes with a privileged ptrace relationship,\nwhich can be abused to ptrace a suid binary and obtain root privileges.\n\nFix both of these by always recording the credentials of the process\nthat is requesting the creation of the ptrace relationship:\ncurrent_cred() can\u0027t change under us, and current is the proper subject\nfor access control.\n\nThis change is theoretically userspace-visible, but I am not aware of\nany code that it will actually break.\n\nFixes: 64b875f7ac8a (\"ptrace: Capture the ptracer\u0027s creds not PT_PTRACE_CAP\")\nSigned-off-by: Jann Horn \u003cjannh@google.com\u003e\nAcked-by: Oleg Nesterov \u003coleg@redhat.com\u003e\nCc: stable@vger.kernel.org\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n" }, { "commit": "6ae3483d411638e471ca0498629b17939f1c20f4", "tree": "82be8900f71803ee7924797ce064541fd4545304", "parents": [ "c7ff0e918a7cb39f6bfb2a7bdc30199986ff1571" ], "author": { "name": "Sebastian Ott", "email": "sebott@linux.ibm.com", "time": "Thu Jun 27 15:47:13 2019 +0200" }, "committer": { "name": "Vasily Gorbik", "email": "gor@linux.ibm.com", "time": "Thu Jul 04 13:13:59 2019 +0200" }, "message": "s390/pci: correctly handle MIO opt-out\n\nDo not issue CLP_SET_ENABLE_MIO after opting out of MIO instruction\nusage.
