Add calls to rseq_signal_deliver() and rseq_syscall() to introduce RSEQ support. 1. Call the rseq_signal_deliver() function to fixup on the pre-signal frame when a signal is delivered on top of a restartable sequence critical section. 2. Check that system calls are not invoked from within rseq critical sections by invoking rseq_signal() from ret_from_syscall(). With CONFIG_DEBUG_RSEQ, such behavior results in termination of the process with SIGSEGV.

2022-03-22ALSA: pci: fix reading of swapped values from pcmreg in AC97 codecGiacomo Guiduzzi
Tests 72 and 78 for ALSA in kselftest fail due to reading inconsistent values from some devices on a VirtualBox Virtual Machine using the snd_intel8x0 driver for the AC'97 Audio Controller device. Taking for example test number 72, this is what the test reports: "Surround Playback Volume.0 expected 1 but read 0, is_volatile 0" "Surround Playback Volume.1 expected 0 but read 1, is_volatile 0" These errors repeat for each value from 0 to 31. Taking a look at these error messages it is possible to notice that the written values are read back swapped. When the write is performed, these values are initially stored in an array used to sanity-check them and write them in the pcmreg array. To write them, the two one-byte values are packed together in a two-byte variable through bitwise operations: the first value is shifted left by one byte and the second value is stored in the right byte through a bitwise OR. When reading the values back, right shifts are performed to retrieve the previously stored bytes. These shifts are executed in the wrong order, thus reporting the values swapped as shown above. This patch fixes this mistake by reversing the read operations' order.

2022-03-22ALSA: pcm: Add stream lock during PCM reset ioctl operationsTakashi Iwai
snd_pcm_reset() is a non-atomic operation, and it's allowed to run during the PCM stream running. It implies that the manipulation of hw_ptr and other parameters might be racy. This patch adds the PCM stream lock at appropriate places in snd_pcm_*_reset() actions for covering that.

2022-03-22ALSA: pcm: Fix races among concurrent prealloc proc writesTakashi Iwai
We have no protection against concurrent PCM buffer preallocation changes via proc files, and it may potentially lead to UAF or some weird problem.

2022-03-22ALSA: pcm: Fix races among concurrent prepare and hw_params/hw_free callsTakashi Iwai
Like the previous fixes to hw_params and hw_free ioctl races, we need to paper over the concurrent prepare ioctl calls against hw_params and hw_free, too. This patch implements the locking with the existing runtime->buffer_mutex for prepare ioctls. Unlike the previous case for snd_pcm_hw_hw_params() and snd_pcm_hw_free(), snd_pcm_prepare() is performed to the linked streams, hence the lock can't be applied simply on the top. For tracking the lock in each linked substream, we modify snd_pcm_action_group() slightly and apply the buffer_mutex for the case stream_lock=false (formerly there was no lock applied) there.

2022-03-22ALSA: pcm: Fix races among concurrent read/write and buffer changesTakashi Iwai
In the current PCM design, the read/write syscalls (as well as the equivalent ioctls) are allowed before the PCM stream is running, that is, at PCM PREPARED state. Meanwhile, we also allow to re-issue hw_params and hw_free ioctl calls at the PREPARED state that may change or free the buffers, too. The problem is that there is no protection against those mix-ups. This patch applies the previously introduced runtime->buffer_mutex to the read/write operations so that the concurrent hw_params or hw_free call can no longer interfere during the operation. The mutex is unlocked before scheduling, so we don't take it too long.

2022-03-22ALSA: pcm: Fix races among concurrent hw_params and hw_free callsTakashi Iwai
Currently we have neither proper check nor protection against the concurrent calls of PCM hw_params and hw_free ioctls, which may result in a UAF. Since the existing PCM stream lock can't be used for protecting the whole ioctl operations, we need a new mutex to protect those racy calls. This patch introduced a new mutex, runtime->buffer_mutex, and applies it to both hw_params and hw_free ioctl code paths. Along with it, the both functions are slightly modified (the mmap_count check is moved into the state-check block) for code simplicity.

2022-03-22xtensa: define update_mmu_tlb functionMax Filippov
Before the commit f9ce0be71d1f ("mm: Cleanup faultaround and finish_fault() codepaths") there was a call to update_mmu_cache in alloc_set_pte that used to invalidate TLB entry caching invalid PTE that caused a page fault. That commit removed that call so now invalid TLB entry survives causing repetitive page faults on the CPU that took the initial fault until that TLB entry is occasionally evicted. This issue is spotted by the xtensa TLB sanity checker. Fix this issue by defining update_mmu_tlb function that flushes TLB entry for the faulting address.
