bcachefs: Repair pass for scanning for btree nodes

2024-04-03T18:44:18Z

If a btree root or interior btree node goes bad, we're going to lose a lot of data, unless we can recover the nodes that it pointed to by scanning. Fortunately btree node headers are fully self describing, and additionally the magic number is xored with the filesytem UUID, so we can do so safely. This implements the scanning - next patch will rework topology repair to make use of the found nodes. Signed-off-by: Kent Overstreet

bcachefs: Etyzinger cleanups

2024-04-03T18:44:18Z

Pull out eytzinger.c and kill eytzinger_cmp_fn. We now provide eytzinger0_sort and eytzinger0_sort_r, which use the standard cmp_func_t and cmp_r_func_t callbacks. Signed-off-by: Kent Overstreet

bcachefs: Split out recovery_passes.c

2024-04-01T00:36:11Z

We've grown a fair amount of code for managing recovery passes; tracking which ones we're running, which ones need to be run, and flagging in the superblock which ones need to be run on the next recovery. So it's worth splitting out into its own file, this code is pretty different from the code in recovery.c. Signed-off-by: Kent Overstreet

bcachefs: Silence gcc warnings about arm arch ABI drift

2024-03-14T01:22:25Z

32-bit arm builds emit a lot of spam like this: fs/bcachefs/backpointers.c: In function ‘extent_matches_bp’: fs/bcachefs/backpointers.c:15:13: note: parameter passing for argument of type ‘struct bch_backpointer’ changed in GCC 9.1 Apply the change from commit ebcc5928c5d9 ("arm64: Silence gcc warnings about arch ABI drift") to fs/bcachefs/ to silence them.

bcachefs: factor out thread_with_file, thread_with_stdio

2024-01-06T04:24:19Z

thread_with_stdio now knows how to handle input - fsck can now prompt to fix errors. Signed-off-by: Kent Overstreet

bcachefs: bch_sb_field_downgrade

2024-01-01T16:47:07Z

Add a new superblock section that contains a list of { minor version, recovery passes, errors_to_fix } that is - a list of recovery passes that must be run when downgrading past a given version, and a list of errors to silently fix. The upcoming disk accounting rewrite is not going to be fully compatible: we're going to have to regenerate accounting both when upgrading to the new version, and also from downgrading from the new version, since the new method of doing disk space accounting is a completely different architecture based on deltas, and synchronizing them for every jounal entry write to maintain compatibility is going to be too expensive and impractical.

bcachefs: Factor out darray resize slowpath

2024-01-01T16:46:52Z

Move the slowpath (actually growing the darray) to an out-of-line function; also, add some helpers for the upcoming btree write buffer rewrite. Signed-off-by: Kent Overstreet

bcachefs: bch_sb_field_errors

2023-11-02T01:11:08Z

Add a new superblock section to keep counts of errors seen since filesystem creation: we'll be addingcounters for every distinct fsck error. The new superblock section has entries of the for [ id, count, time_of_last_error ]; this is intended to let us see what errors are occuring - and getting fixed - via show-super output.
