2019-08-16ASoC: imx-audmux: Add driver suspend and resume to support MEGA FastShengjiu Wang
For i.MX6 SoloX, there is a mode of the SoC to shutdown all power source of modules during system suspend and resume procedure. Thus, AUDMUX needs to save all the values of registers before the system suspend and restore them after the system resume.

2019-08-16ALSA: hda - Expand pin_match function to match upcoming new tblsHui Wang
With the existing pintbl, we already have many entries in it. it is better to figure out a new way to reduce the size of the pintbl. We plan to define a new tbl which will match more machines with a single tbl, To do that, this function doesn't need to match all valid pins between machine and tbl, it just needs to match all pins defined in the tbl with the machine. And the plan is to move some tbls from pin_fixup_tbl to fallback_pin_fixup_tbl gradually. Signed-off-by: Hui Wang <hui.wang@canonical.com> Signed-off-by: Takashi Iwai <tiwai@suse.de>

2019-08-15net/packet: fix race in tpacket_snd()Eric Dumazet
packet_sendmsg() checks tx_ring.pg_vec to decide if it must call tpacket_snd(). Problem is that the check is lockless, meaning another thread can issue a concurrent setsockopt(PACKET_TX_RING ) to flip tx_ring.pg_vec back to NULL. Given that tpacket_snd() grabs pg_vec_lock mutex, we can perform the check again to solve the race. syzbot reported : kasan: CONFIG_KASAN_INLINE enabled kasan: GPF could be caused by NULL-ptr deref or user memory access general protection fault: 0000 [#1] PREEMPT SMP KASAN CPU: 1 PID: 11429 Comm: syz-executor394 Not tainted 5.3.0-rc4+ #101 Hardware name: Google Google Compute Engine/Google Compute Engine, BIOS Google 01/01/2011 RIP: 0010:packet_lookup_frame+0x8d/0x270 net/packet/af_packet.c:474 Code: c1 ee 03 f7 73 0c 80 3c 0e 00 0f 85 cb 01 00 00 48 8b 0b 89 c0 4c 8d 24 c1 48 b8 00 00 00 00 00 fc ff df 4c 89 e1 48 c1 e9 03 <80> 3c 01 00 0f 85 94 01 00 00 48 8d 7b 10 4d 8b 3c 24 48 b8 00 00 RSP: 0018:ffff88809f82f7b8 EFLAGS: 00010246 RAX: dffffc0000000000 RBX: ffff8880a45c7030 RCX: 0000000000000000 RDX: 0000000000000000 RSI: 1ffff110148b8e06 RDI: ffff8880a45c703c RBP: ffff88809f82f7e8 R08: ffff888087aea200 R09: fffffbfff134ae50 R10: fffffbfff134ae4f R11: ffffffff89a5727f R12: 0000000000000000 R13: 0000000000000001 R14: ffff8880a45c6ac0 R15: 0000000000000000 FS: 00007fa04716f700(0000) GS:ffff8880ae900000(0000) knlGS:0000000000000000 CS: 0010 DS: 0000 ES: 0000 CR0: 0000000080050033 CR2: 00007fa04716edb8 CR3: 0000000091eb4000 CR4: 00000000001406e0 DR0: 0000000000000000 DR1: 0000000000000000 DR2: 0000000000000000 DR3: 0000000000000000 DR6: 00000000fffe0ff0 DR7: 0000000000000400 Call Trace: packet_current_frame net/packet/af_packet.c:487 [inline] tpacket_snd net/packet/af_packet.c:2667 [inline] packet_sendmsg+0x590/0x6250 net/packet/af_packet.c:2975 sock_sendmsg_nosec net/socket.c:637 [inline] sock_sendmsg+0xd7/0x130 net/socket.c:657 ___sys_sendmsg+0x3e2/0x920 net/socket.c:2311 __sys_sendmmsg+0x1bf/0x4d0 net/socket.c:2413 __do_sys_sendmmsg net/socket.c:2442 [inline] __se_sys_sendmmsg net/socket.c:2439 [inline] __x64_sys_sendmmsg+0x9d/0x100 net/socket.c:2439 do_syscall_64+0xfd/0x6a0 arch/x86/entry/common.c:296 entry_SYSCALL_64_after_hwframe+0x49/0xbe Fixes: 69e3c75f4d54 ("net: TX_RING and packet mmap") Signed-off-by: Eric Dumazet <edumazet@google.com> Reported-by: syzbot <syzkaller@googlegroups.com> Signed-off-by: David S.

2019-08-15dm integrity: fix a crash due to BUG_ON in __journal_read_write()Mikulas Patocka
Fix a crash that was introduced by the commit 724376a04d1a. The crash is reported here: https://gitlab.com/cryptsetup/cryptsetup/issues/468 When reading from the integrity device, the function dm_integrity_map_continue calls find_journal_node to find out if the location to read is present in the journal. Then, it calculates how many sectors are consecutively stored in the journal. Then, it locks the range with add_new_range and wait_and_add_new_range. The problem is that during wait_and_add_new_range, we hold no locks (we don't hold ic->endio_wait.lock and we don't hold a range lock), so the journal may change arbitrarily while wait_and_add_new_range sleeps. The code then goes to __journal_read_write and hits BUG_ON(journal_entry_get_sector(je) != logical_sector); because the journal has changed. In order to fix this bug, we need to re-check the journal location after wait_and_add_new_range. We restrict the length to one block in order to not complicate the code too much.

2019-08-15dm zoned: properly handle backing device failureDmitry Fomichev
dm-zoned is observed to lock up or livelock in case of hardware failure or some misconfiguration of the backing zoned device. This patch adds a new dm-zoned target function that checks the status of the backing device. If the request queue of the backing device is found to be in dying state or the SCSI backing device enters offline state, the health check code sets a dm-zoned target flag prompting all further incoming I/O to be rejected. In order to detect backing device failures timely, this new function is called in the request mapping path, at the beginning of every reclaim run and before performing any metadata I/O. The proper way out of this situation is to do dmsetup remove <dm-zoned target> and recreate the target when the problem with the backing device is resolved.

2019-08-15dm zoned: improve error handling in i/o map codeDmitry Fomichev
Some errors are ignored in the I/O path during queueing chunks for processing by chunk works. Since at least these errors are transient in nature, it should be possible to retry the failed incoming commands. The fix - Errors that can happen while queueing chunks are carried upwards to the main mapping function and it now returns DM_MAPIO_REQUEUE for any incoming requests that can not be properly queued. Error logging/debug messages are added where needed.

2019-08-15dm zoned: improve error handling in reclaimDmitry Fomichev
There are several places in reclaim code where errors are not propagated to the main function, dmz_reclaim(). This function is responsible for unlocking zones that might be still locked at the end of any failed reclaim iterations. As the result, some device zones may be left permanently locked for reclaim, degrading target's capability to reclaim zones. This patch fixes these issues as follows - Make sure that dmz_reclaim_buf(), dmz_reclaim_seq_data() and dmz_reclaim_rnd_data() return error codes to the caller. dmz_reclaim() function is renamed to dmz_do_reclaim() to avoid clashing with "struct dmz_reclaim" and is modified to return the error to the caller. dmz_get_zone_for_reclaim() now returns an error instead of NULL pointer and reclaim code checks for that error. Error logging/debug messages are added where necessary.

2019-08-15dm kcopyd: always complete failed jobsDmitry Fomichev
This patch fixes a problem in dm-kcopyd that may leave jobs in complete queue indefinitely in the event of backing storage failure. This behavior has been observed while running 100% write file fio workload against an XFS volume created on top of a dm-zoned target device. If the underlying storage of dm-zoned goes to offline state under I/O, kcopyd sometimes never issues the end copy callback and dm-zoned reclaim work hangs indefinitely waiting for that completion. This behavior was traced down to the error handling code in process_jobs() function that places the failed job to complete_jobs queue, but doesn't wake up the job handler. In case of backing device failure, all outstanding jobs may end up going to complete_jobs queue via this code path and then stay there forever because there are no more successful I/O jobs to wake up the job handler. This patch adds a wake() call to always wake up kcopyd job wait queue for all I/O jobs that fail before dm_io() gets called for that job. The patch also sets the write error status in all sub jobs that are failed because their master job has failed.

Revert the commit bd293d071ffe65e645b4d8104f9d8fe15ea13862. The proper fix has been made available with commit d0a255e795ab ("loop: set PF_MEMALLOC_NOIO for the worker thread"). Note that the fix offered by commit bd293d071ffe doesn't really prevent the deadlock from occuring - if we look at the stacktrace reported by Junxiao Bi, we see that it hangs in bit_wait_io and not on the mutex - i.e. it has already successfully taken the mutex. Changing the mutex from mutex_lock to mutex_trylock won't help with deadlocks that happen afterwards.

2019-08-15ALSA: usb-audio: Fix a stack buffer overflow bug in check_input_termHui Peng
`check_input_term` recursively calls itself with input from device side (e.g., uac_input_terminal_descriptor.bCSourceID) as argument (id). In `check_input_term`, if `check_input_term` is called with the same `id` argument as the caller, it triggers endless recursive call, resulting kernel space stack overflow. This patch fixes the bug by adding a bitmap to `struct mixer_build` to keep track of the checked ids and stop the execution if some id has been checked (similar to how parse_audio_unit handles unitid argument).

This patch may fix two issues: First, when IOSQE_IO_DRAIN set, the next IOs need to be inserted into defer list to delay execution, but link io will be actively scheduled to run by calling io_queue_sqe. Second, when multiple LINK_IOs are inserted together with defer_list, the LINK_IO is no longer keep order. |-------------| | LINK_IO | ----> insert to defer_list ----------- |-------------| | | LINK_IO | ----> insert to defer_list ----------| |-------------| | | LINK_IO | ----> insert to defer_list ----------| |-------------| | | NORMAL_IO | ----> insert to defer_list ----------| |-------------| | | queue_work at same time <-----| Fixes: 9e645e1105c ("io_uring: add support for sqe links") Signed-off-by: Jackie Liu <liuyun01@kylinos.cn> Signed-off-by: Jens Axboe <axboe@kernel.dk>

2019-08-15io_uring: fix manual setup of iov_iter for fixed buffersAleix Roca Nonell
Commit bd11b3a391e3 ("io_uring: don't use iov_iter_advance() for fixed buffers") introduced an optimization to avoid using the slow iov_iter_advance by manually populating the iov_iter iterator in some cases. However, the computation of the iterator count field was erroneous: The first bvec was always accounted for an extent of page size even if the bvec length was smaller. In consequence, some I/O operations on fixed buffers were unable to operate on the full extent of the buffer, consistently skipping some bytes at the end of it.

2019-08-15PCI: Reset both NVIDIA GPU and HDA in ThinkPad P50 workaroundLyude Paul
quirk_reset_lenovo_thinkpad_50_nvgpu() resets NVIDIA GPUs to work around an apparent BIOS defect. It previously used pci_reset_function(), and the available method was a bus reset, which was fine because there was only one function on the bus. After b516ea586d71 ("PCI: Enable NVIDIA HDA controllers"), there are now two functions (the HDA controller and the GPU itself) on the bus, so the reset fails. Use pci_reset_bus() explicitly instead of pci_reset_function() since it's OK to reset both devices.

2019-08-15ASoC: core: Move pcm_mutex up to card level from snd_soc_pcm_runtimePeter Ujfalusi
The pcm_mutex is used to prevent concurrent execution of snd_pcm_ops callbacks. This works fine most of the cases but it can not handle setups when the same DAI is used by different rtd, for example: pcm3168a have two DAIs: one for Playback and one for Capture. If the codec is connected to a single CPU DAI we need to have two dai_link to support both playback and capture. In this case the snd_pcm_ops callbacks can be executed in parallel causing unexpected races in DAI drivers. By moving the pcm_mutex up to card level this can be solved while - hopefully - not breaking other setups.
