2023-02-10xfs: revert commit 8954c44ff477xfs-6.3-merge-2Darrick J. Wong
The name passed into __xfs_xattr_put_listent is exactly namelen bytes long and not null-terminated. Passing namelen+1 to the strscpy function strscpy(offset, (char *)name, namelen + 1); is therefore wrong. Go back to the old code, which works fine because strncpy won't find a null in @name and stops after namelen bytes. It really could be a memcpy call, but it worked for years.

2023-02-05xfs: don't use BMBT btree split workers for IO completionxfs-6.3-merge-1Dave Chinner
When we split a BMBT due to record insertion, we offload it to a worker thread because we can be deep in the stack when we try to allocate a new block for the BMBT. Allocation can use several kilobytes of stack (full memory reclaim, swap and/or IO path can end up on the stack during allocation) and we can already be several kilobytes deep in the stack when we need to split the BMBT. A recent workload demonstrated a deadlock in this BMBT split offload. It requires several things to happen at once: 1. two inodes need a BMBT split at the same time, one must be unwritten extent conversion from IO completion, the other must be from extent allocation. 2. there must be a no available xfs_alloc_wq worker threads available in the worker pool. 3. There must be sustained severe memory shortages such that new kworker threads cannot be allocated to the xfs_alloc_wq pool for both threads that need split work to be run 4. The split work from the unwritten extent conversion must run first. 5. when the BMBT block allocation runs from the split work, it must loop over all AGs and not be able to either trylock an AGF successfully, or each AGF is is able to lock has no space available for a single block allocation. 6. The BMBT allocation must then attempt to lock the AGF that the second task queued to the rescuer thread already has locked before it finds an AGF it can allocate from. At this point, we have an ABBA deadlock between tasks queued on the xfs_alloc_wq rescuer thread and a locked AGF. i.e. The queued task holding the AGF lock can't be run by the rescuer thread until the task the rescuer thread is runing gets the AGF lock.... This is a highly improbably series of events, but there it is. There's a couple of ways to fix this, but the easiest way to ensure that we only punt tasks with a locked AGF that holds enough space for the BMBT block allocations to the worker thread. This works for unwritten extent conversion in IO completion (which doesn't have a locked AGF and space reservations) because we have tight control over the IO completion stack. It is typically only 6 functions deep when xfs_btree_split() is called because we've already offloaded the IO completion work to a worker thread and hence we don't need to worry about stack overruns here. The other place we can be called for a BMBT split without a preceeding allocation is __xfs_bunmapi() when punching out the center of an existing extent. We don't remove extents in the IO path, so these operations don't tend to be called with a lot of stack consumed. Hence we don't really need to ship the split off to a worker thread in these cases, either. Signed-off-by: Dave Chinner <dchinner@redhat.com> Reviewed-by: Darrick J.

2023-01-29Revert "mm/compaction: fix set skip in fast_find_migrateblock"Vlastimil Babka
This reverts commit 7efc3b7261030da79001c00d92bc3392fd6c664c. We have got openSUSE reports (Link 1) for 6.1 kernel with khugepaged stalling CPU for long periods of time. Investigation of tracepoint data shows that compaction is stuck in repeating fast_find_migrateblock() based migrate page isolation, and then fails to migrate all isolated pages. Commit 7efc3b726103 ("mm/compaction: fix set skip in fast_find_migrateblock") was suspected as it was merged in 6.1 and in theory can indeed remove a termination condition for fast_find_migrateblock() under certain conditions, as it removes a place that always marks a scanned pageblock from being re-scanned. There are other such places, but those can be skipped under certain conditions, which seems to match the tracepoint data. Testing of revert also appears to have resolved the issue, thus revert the commit until a more robust solution for the original problem is developed. It's also likely this will fix qemu stalls with 6.1 kernel reported in Link 2, but that is not yet confirmed.

2023-01-27ovl: fail on invalid uid/gid mapping at copy upMiklos Szeredi
If st_uid/st_gid doesn't have a mapping in the mounter's user_ns, then copy-up should fail, just like it would fail if the mounter task was doing the copy using "cp -a". There's a corner case where the "cp -a" would succeed but copy up fail: if there's a mapping of the invalid uid/gid (65534 by default) in the user namespace. This is because stat(2) will return this value if the mapping doesn't exist in the current user_ns and "cp -a" will in turn be able to create a file with this uid/gid. This behavior would be inconsistent with POSIX ACL's, which return -1 for invalid uid/gid which result in a failed copy. For consistency and simplicity fail the copy of the st_uid/st_gid are invalid.

2023-01-27io_uring: always prep_async for drain requestsio_uring-6.2-2023-01-27Dylan Yudaken
Drain requests all go through io_drain_req, which has a quick exit in case there is nothing pending (ie the drain is not useful). In that case it can run the issue the request immediately. However for safety it queues it through task work. The problem is that in this case the request is run asynchronously, but the async work has not been prepared through io_req_prep_async. This has not been a problem up to now, as the task work always would run before returning to userspace, and so the user would not have a chance to race with it. However - with IORING_SETUP_DEFER_TASKRUN - this is no longer the case and the work might be defered, giving userspace a chance to change data being referred to in the request. Instead _always_ prep_async for drain requests, which is simpler anyway and removes this issue.

2023-01-27tools: gpio: fix -c option of gpio-event-monIvo Borisov Shopov
Following line should listen for a rising edge and exit after the first one since '-c 1' is provided. # gpio-event-mon -n gpiochip1 -o 0 -r -c 1 It works with kernel 4.19 but it doesn't work with 5.10. In 5.10 the above command doesn't exit after the first rising edge it keep listening for an event forever. The '-c 1' is not taken into an account. The problem is in commit 62757c32d5db ("tools: gpio: add multi-line monitoring to gpio-event-mon"). Before this commit the iterator 'i' in monitor_device() is used for counting of the events (loops). In the case of the above command (-c 1) we should start from 0 and increment 'i' only ones and hit the 'break' statement and exit the process. But after the above commit counting doesn't start from 0, it start from 1 when we listen on one line. It is because 'i' is used from one more purpose, counting of lines (num_lines) and it isn't restore to 0 after following code for (i = 0; i < num_lines; i++) gpiotools_set_bit(&values.mask, i); Restore the initial value of the iterator to 0 in order to allow counting of loops to work for any cases.

2023-01-26treewide: fix up files incorrectly marked executableLinus Torvalds
I'm not exactly clear on what strange workflow causes people to do it, but clearly occasionally some files end up being committed as executable even though they clearly aren't. This is a reprise of commit 90fda63fa115 ("treewide: fix up files incorrectly marked executable"), just with a different set of files (but with the same trivial shell scripting). So apparently we need to re-do this every five years or so, and Joe needs to just keep reminding me to do so ;) Reported-by: Joe Perches <joe@perches.com> Fixes: 523375c943e5 ("drm/vmwgfx: Port vmwgfx to arm64") Fixes: 5c439937775d ("ASoC: codecs: add support for ES8326") Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
