Hi Linus, about the usual batch of fixes... - rebased to rc6 because upstream bugs were interfering with my CI results; also, there's still a bug in memory allocation profiling that Andrew hasn't sent you a fix for, which is keeping me from flipping on leak detection in all my tests - bcachefs devs take note (and anyone dealing with syzbot): I now have a ktest test for building a kernel and running a syzbot reproducer in a single command, see https://evilpiepirate.org/git/ktest.git/commit/?id=3c30e501fb0d1413849cfc4f5832f8f5cff48585 The following changes since commit 59b723cd2adbac2a34fc8e12c74ae26ae45bf230: Linux 6.12-rc6 (2024-11-03 14:05:52 -1000) are available in the Git repository at: git://evilpiepirate.org/bcachefs.git tags/bcachefs-2024-11-07 for you to fetch changes up to 8440da933127fc5330c3d1090cdd612fddbc40eb: bcachefs: Fix UAF in __promote_alloc() error path (2024-11-07 16:48:21 -0500) ---------------------------------------------------------------- bcachefs fixes for 6.12-rc7 Some trivial syzbot fixes, two more serious btree fixes found by looping single_devices.ktest small_nodes: - Topology error on split after merge, where we accidentaly picked the node being deleted for the pivot, resulting in an assertion pop - New nodes being preallocated were left on the freedlist, unlocked, resulting in them sometimes being accidentally freed: this dated from pre-cycle detector, when we could leave them locked. This should have resulted in more explosions and fireworks, but turned out to be surprisingly hard to hit because the preallocated nodes were being used right away. the fix for this is bigger than we'd like - reworking btree list handling was a bit invasive - but we've now got more assertions and it's well tested. - Also another mishandled transaction restart fix (in btree_node_prefetch) - we're almost done with those. ---------------------------------------------------------------- Hongbo Li (1): bcachefs: check the invalid parameter for perf test Kent Overstreet (7): bcachefs: Fix null ptr deref in bucket_gen_get() bcachefs: Fix error handling in bch2_btree_node_prefetch() bcachefs: Ancient versions with bad bkey_formats are no longer supported bcachefs: Fix topology errors on split after merge bcachefs: Ensure BCH_FS_may_go_rw is set before exiting recovery bcachefs: btree_cache.freeable list fixes bcachefs: Fix UAF in __promote_alloc() error path Pei Xiao (1): bcachefs: add check NULL return of bio_kmalloc in journal_read_bucket Piotr Zalewski (1): bcachefs: Change OPT_STR max to be 1 less than the size of choices array fs/bcachefs/bkey.c | 7 +-- fs/bcachefs/btree_cache.c | 107 ++++++++++++++++++++++-------------- fs/bcachefs/btree_cache.h | 2 + fs/bcachefs/btree_node_scan.c | 2 +- fs/bcachefs/btree_update_interior.c | 30 ++++++---- fs/bcachefs/buckets.h | 19 ++++--- fs/bcachefs/errcode.h | 1 + fs/bcachefs/io_read.c | 10 ++-- fs/bcachefs/io_write.c | 7 +-- fs/bcachefs/journal_io.c | 2 + fs/bcachefs/opts.c | 4 +- fs/bcachefs/recovery.c | 7 +++ fs/bcachefs/recovery_passes.c | 6 ++ fs/bcachefs/tests.c | 5 ++ 14 files changed, 131 insertions(+), 78 deletions(-)
