2024-06-07kbuild: explicitly run mksysmap as sed script from link-vmlinux.shRichard Acayan
In commit b18b047002b7 ("kbuild: change scripts/mksysmap into sed script"), the mksysmap script was transformed into a sed script, made directly executable with "#!/bin/sed -f". Apparently, the path to sed is different on NixOS. The shebang can't use the env command, otherwise the "sed -f" command would be treated as a single argument. This can be solved with the -S flag, but that is a GNU extension. Explicitly use sed instead of relying on the executable shebang to fix NixOS builds without breaking build environments using Busybox.

2024-06-06btrfs: protect folio::private when attaching extent buffer foliosQu Wenruo
[BUG] Since v6.8 there are rare kernel crashes reported by various people, the common factor is bad page status error messages like this: BUG: Bad page state in process kswapd0 pfn:d6e840 page: refcount:0 mapcount:0 mapping:000000007512f4f2 index:0x2796c2c7c pfn:0xd6e840 aops:btree_aops ino:1 flags: 0x17ffffe0000008(uptodate|node=0|zone=2|lastcpupid=0x3fffff) page_type: 0xffffffff() raw: 0017ffffe0000008 dead000000000100 dead000000000122 ffff88826d0be4c0 raw: 00000002796c2c7c 0000000000000000 00000000ffffffff 0000000000000000 page dumped because: non-NULL mapping [CAUSE] Commit 09e6cef19c9f ("btrfs: refactor alloc_extent_buffer() to allocate-then-attach method") changes the sequence when allocating a new extent buffer. Previously we always called grab_extent_buffer() under mapping->i_private_lock, to ensure the safety on modification on folio::private (which is a pointer to extent buffer for regular sectorsize). This can lead to the following race: Thread A is trying to allocate an extent buffer at bytenr X, with 4 4K pages, meanwhile thread B is trying to release the page at X + 4K (the second page of the extent buffer at X). Thread A | Thread B -----------------------------------+------------------------------------- | btree_release_folio() | | This is for the page at X + 4K, | | Not page X. | | alloc_extent_buffer() | |- release_extent_buffer() |- filemap_add_folio() for the | | |- atomic_dec_and_test(eb->refs) | page at bytenr X (the first | | | | page). | | | | Which returned -EEXIST. | | | | | | | |- filemap_lock_folio() | | | | Returned the first page locked. | | | | | | | |- grab_extent_buffer() | | | | |- atomic_inc_not_zero() | | | | | Returned false | | | | |- folio_detach_private() | | |- folio_detach_private() for X | |- folio_test_private() | | |- folio_test_private() | Returned true | | | Returned true |- folio_put() | |- folio_put() Now there are two puts on the same folio at folio X, leading to refcount underflow of the folio X, and eventually causing the BUG_ON() on the page->mapping. The condition is not that easy to hit: - The release must be triggered for the middle page of an eb If the release is on the same first page of an eb, page lock would kick in and prevent the race. - folio_detach_private() has a very small race window It's only between folio_test_private() and folio_clear_private(). That's exactly when mapping->i_private_lock is used to prevent such race, and commit 09e6cef19c9f ("btrfs: refactor alloc_extent_buffer() to allocate-then-attach method") screwed that up. At that time, I thought the page lock would kick in as filemap_release_folio() also requires the page to be locked, but forgot the filemap_release_folio() only locks one page, not all pages of an extent buffer. [FIX] Move all the code requiring i_private_lock into attach_eb_folio_to_filemap(), so that everything is done with proper lock protection. Furthermore to prevent future problems, add an extra lockdep_assert_locked() to ensure we're holding the proper lock. To reproducer that is able to hit the race (takes a few minutes with instrumented code inserting delays to alloc_extent_buffer()): #!/bin/sh drop_caches () { while(true); do echo 3 > /proc/sys/vm/drop_caches echo 1 > /proc/sys/vm/compact_memory done } run_tar () { while(true); do for x in `seq 1 80` ; do tar cf /dev/zero /mnt > /dev/null & done wait done } mkfs.btrfs -f -d single -m single /dev/vda mount -o noatime /dev/vda /mnt # create 200,000 files, 1K each ./simoop -n 200000 -E -f 1k /mnt drop_caches & (run_tar) Reported-by: Linus Torvalds <torvalds@linux-foundation.org> Link: https://lore.kernel.org/linux-btrfs/CAHk-=wgt362nGfScVOOii8cgKn2LVVHeOvOA7OBwg1OwbuJQcw@mail.gmail.com/ Reported-by: Mikhail Gavrilov <mikhail.v.gavrilov@gmail.com> Link: https://lore.kernel.org/lkml/CABXGCsPktcHQOvKTbPaTwegMExije=Gpgci5NW=hqORo-s7diA@mail.gmail.com/ Reported-by: Toralf Förster <toralf.foerster@gmx.de> Link: https://lore.kernel.org/linux-btrfs/e8b3311c-9a75-4903-907f-fc0f7a3fe423@gmx.de/ Reported-by: syzbot+f80b066392366b4af85e@syzkaller.appspotmail.com Fixes: 09e6cef19c9f ("btrfs: refactor alloc_extent_buffer() to allocate-then-attach method") CC: stable@vger.kernel.org # 6.8+ CC: Chris Mason <clm@fb.com> Reviewed-by: Filipe Manana <fdmanana@suse.com> Reviewed-by: Josef Bacik <josef@toxicpanda.com> Signed-off-by: Qu Wenruo <wqu@suse.com> Reviewed-by: David Sterba <dsterba@suse.com> Signed-off-by: David Sterba <dsterba@suse.com>

2024-06-06drm/print: Add generic drm dev printk functionMichal Wajdeczko
We already have some drm printk functions that need to duplicate a code to get a similar format of the final result, for example: [ ] 0000:00:00.0: [drm:foo] bar [ ] 0000:00:00.0: [drm] foo bar [ ] 0000:00:00.0: [drm] *ERROR* foo Add a generic __drm_dev_vprintk() function that can format the final message like all other existing function do and allows us to keep the formatting code in one place.

2024-06-06drm/xe/xe_gt_debugfs: Add synchronous gt reset debugfsJonathan Cavitt
We currently have debugfs support that allows the userspace to initiate an asynchronous gt reset on command. However, userspace may also wish to wait for the completion of the gt reset before performing any additional work. To that end, add a version of the force_reset gt debugfs function that operates synchronously.

Matthieu Baerts says: ==================== selftests: net: lib: small fixes While looking at using 'lib.sh' for the MPTCP selftests [1], we found some small issues with 'lib.sh'. Here they are: - Patch 1: fix 'errexit' (set -e) support with busywait. 'errexit' is supported in some functions, not all. A fix for v6.8+. - Patch 2: avoid confusing error messages linked to the cleaning part when the netns setup fails. A fix for v6.8+. - Patch 3: set a variable as local to avoid accidentally changing the value of a another one with the same name on the caller side. A fix for v6.10-rc1+.

2024-06-06selftests: net: lib: set 'i' as localMatthieu Baerts (NGI0)
Without this, the 'i' variable declared before could be overridden by accident, e.g. for i in "${@}"; do __ksft_status_merge "${i}" ## 'i' has been modified foo "${i}" ## using 'i' with an unexpected value done After a quick look, it looks like 'i' is currently not used after having been modified in __ksft_status_merge(), but still, better be safe than sorry. I saw this while modifying the same file, not because I suspected an issue somewhere.

2024-06-06selftests: net: lib: avoid error removing empty netns nameMatthieu Baerts (NGI0)
If there is an error to create the first netns with 'setup_ns()', 'cleanup_ns()' will be called with an empty string as first parameter. The consequences is that 'cleanup_ns()' will try to delete an invalid netns, and wait 20 seconds if the netns list is empty. Instead of just checking if the name is not empty, convert the string separated by spaces to an array. Manipulating the array is cleaner, and calling 'cleanup_ns()' with an empty array will be a no-op.
