2021-03-27io_uring: don't cancel extra on files matchPavel Begunkov
As tasks always wait and kill their io-wq on exec/exit, files are of no more concern to us, so we don't need to specifically cancel them by hand in those cases. Moreover we should not, because io_match_task() looks at req->task->files now, which is always true and so leads to extra cancellations, that wasn't a case before per-task io-wq.

2021-03-27Revert "signal: don't allow STOP on PF_IO_WORKER threads"Jens Axboe
This reverts commit 4db4b1a0d1779dc159f7b87feb97030ec0b12597. The IO threads allow and handle SIGSTOP now, so don't special case them anymore in task_set_jobctl_pending(). Signed-off-by: Jens Axboe <axboe@kernel.dk>
2021-03-27Revert "kernel: freezer should treat PF_IO_WORKER like PF_KTHREAD for freezing"Jens Axboe
This reverts commit 15b2219facadec583c24523eed40fa45865f859f. Before IO threads accepted signals, the freezer using take signals to wake up an IO thread would cause them to loop without any way to clear the pending signal. That is no longer the case, so stop special casing PF_IO_WORKER in the freezer. Signed-off-by: Jens Axboe <axboe@kernel.dk>
2021-03-27Revert "kernel: treat PF_IO_WORKER like PF_KTHREAD for ptrace/signals"Jens Axboe
This reverts commit 6fb8f43cede0e4bd3ead847de78d531424a96be9. The IO threads do allow signals now, including SIGSTOP, and we can allow ptrace attach. Attaching won't reveal anything interesting for the IO threads, but it will allow eg gdb to attach to a task with io_urings and IO threads without complaining. And once attached, it will allow the usual introspection into regular threads. Signed-off-by: Jens Axboe <axboe@kernel.dk>
2021-03-27Revert "signal: don't allow sending any signals to PF_IO_WORKER threads"Jens Axboe
This reverts commit 5be28c8f85ce99ed2d329d2ad8bdd18ea19473a5. IO threads now take signals just fine, so there's no reason to limit them specifically. Revert the change that prevented that from happening. Signed-off-by: Jens Axboe <axboe@kernel.dk>
2021-03-27kernel: stop masking signals in create_io_thread()Jens Axboe
This is racy - move the blocking into when the task is created and we're marking it as PF_IO_WORKER anyway. The IO threads are now prepared to handle signals like SIGSTOP as well, so clear that from the mask to allow proper stopping of IO threads. Acked-by: "Eric W.

2021-03-27io_uring: handle signals for IO threads like a normal threadJens Axboe
We go through various hoops to disallow signals for the IO threads, but there's really no reason why we cannot just allow them. The IO threads never return to userspace like a normal thread, and hence don't go through normal signal processing. Instead, just check for a pending signal as part of the work loop, and call get_signal() to handle it for us if anything is pending. With that, we can support receiving signals, including special ones like SIGSTOP. Acked-by: "Eric W. Biederman" <ebiederm@xmission.com> Signed-off-by: Jens Axboe <axboe@kernel.dk>
2021-03-27block: don't create too many partitionsMing Lei
Commit a33df75c6328 ("block: use an xarray for disk->part_tbl") drops the check on max supported number of partitionsr, and allows partition with bigger partition numbers to be added. However, ->bd_partno is defined as u8, so partition index of xarray table may not match with ->bd_partno. Then delete_partition() may delete one unmatched partition, and caused use-after-free.

2021-03-26smb3: fix cached file size problems in duplicate extents (reflink)Steve French
There were two problems (one of which could cause data corruption) that were noticed with duplicate extents (ie reflink) when debugging why various xfstests were being incorrectly skipped (e.g. generic/138, generic/140, generic/142). First, we were not updating the file size locally in the cache when extending a file due to reflink (it would refresh after actimeo expires) but xfstest was checking the size immediately which was still 0 so caused the test to be skipped. Second, we were setting the target file size (which could shrink the file) in all cases to the end of the reflinked range rather than only setting the target file size when reflink would extend the file.

2021-03-26cifs: Silently ignore unknown oplock break handleVincent Whitchurch
Make SMB2 not print out an error when an oplock break is received for an unknown handle, similar to SMB1. The debug message which is printed for these unknown handles may also be misleading, so fix that too. The SMB2 lease break path is not affected by this patch. Without this, a program which writes to a file from one thread, and opens, reads, and writes the same file from another thread triggers the below errors several times a minute when run against a Samba server configured with "smb2 leases = no". CIFS: VFS: \\192.168.0.1 No task to wake, unknown frame received!

2021-03-26cifs: revalidate mapping when we open files for SMB1 POSIXRonnie Sahlberg
RHBZ: 1933527 Under SMB1 + POSIX, if an inode is reused on a server after we have read and cached a part of a file, when we then open the new file with the re-cycled inode there is a chance that we may serve the old data out of cache to the application. This only happens for SMB1 (deprecated) and when posix are used. The simplest solution to avoid this race is to force a revalidate on smb1-posix open.
