bcachefs: Make bkey_fsck_err() a wrapper around fsck_err()

2024-08-14T03:00:50+00:00

bkey_fsck_err() was added as an interface that looks like fsck_err(), but previously all it did was ensure that the appropriate error counter was incremented in the superblock. This is a cleanup and bugfix patch that converts it to a wrapper around fsck_err(). This is needed to fix an issue with the upgrade path to disk_accounting_v3, where the "silent fix" error list now includes bkey_fsck errors; fsck_err() handles this in a unified way, and since we need to change printing of bkey fsck errors from the caller to the inner bkey_fsck_err() calls, this ends up being a pretty big change. Als,, rename .invalid() methods to .validate(), for clarity, while we're changing the function signature anyways (to drop the printbuf argument). Signed-off-by: Kent Overstreet

bcachefs: KEY_TYPE_accounting

2024-07-14T23:00:13+00:00

New key type for the disk space accounting rewrite. - Holds a variable sized array of u64s (may be more than one for accounting e.g. compressed and uncompressed size, or buckets and sectors for a given data type) - Updates are deltas, not new versions of the key: this means updates to accounting can happen via the btree write buffer, which we'll be teaching to accumulate deltas.

bcachefs: Fix array-index-out-of-bounds

2024-06-19T22:27:23+00:00

We use 0 size arrays as markers, but ubsan doesn't know that - cast them to a pointer to fix the splat. Also, make sure this code gets tested a bit more. Signed-off-by: Kent Overstreet

bcachefs: add no_invalid_checks flag

2024-05-09T20:24:30+00:00

Setting this flag on a filesystem results in validity checks being skipped when writing bkeys. This flag will be used by tooling that deliberately injects corruption into a filesystem in order to exercise fsck. It shouldn't be set outside of testing/debugging code.

bcachefs: s/bkey_invalid_flags/bch_validate_flags

2024-05-09T20:23:36+00:00

We're about to start using bch_validate_flags for superblock section validation - it's no longer bkey specific. Signed-off-by: Kent Overstreet

bcachefs: Guard against unknown k.k->type in __bkey_invalid()

2024-05-06T14:58:17+00:00

For forwards compatibility we have to allow unknown key types, and only run the checks that make sense against them. Fix a missing guard on k.k->type being known. Reported-by: syzbot+ae4dc916da3ce51f284f@syzkaller.appspotmail.com Signed-off-by: Kent Overstreet

bcachefs: Interior known are required to have known key types

2024-04-14T22:01:12+00:00

For forwards compatibilyt, we allow bkeys of unknown type in leaf nodes; we can simply ignore metadata we don't understand. Pointers to btree nodes must always be of known types, howwever. Signed-off-by: Kent Overstreet
