Remove bcachefs core code

2025-09-29T20:43:52+00:00

bcachefs was marked 'externally maintained' in 6.17 but the code remained to make the transition smoother. It's now a DKMS module, making the in-kernel code stale, so remove it to avoid any version confusion.

bcachefs: Ancient versions with bad bkey_formats are no longer supported

2024-11-07T21:48:20+00:00

Syzbot found an assertion pop, by generating an ancient filesystem version with an invalid bkey_format (with fields that can overflow) as well as packed keys that aren't representable unpacked. This breaks key comparisons in all sorts of painful ways. Filesystems have been automatically rewriting nodes with such invalid formats for years; we can safely drop support for them.

bcachefs: Fix shift greater than integer size

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: 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: bch2_bkey_format_field_overflows()

2024-05-08T18:57:19+00:00

Fix another shift-by-64 by factoring out a common helper for bch2_bkey_format_invalid() and bformat_needs_redo() (where it was already fixed). Reported-by: syzbot+9833a1d29d4a44361e2c@syzkaller.appspotmail.com Signed-off-by: Kent Overstreet

bcachefs: Improve move_extent tracepoint

2024-01-21T18:27:09+00:00

Also print out the data_opts, so that we can see what specifically is being done to an extent. Signed-off-by: Kent Overstreet

bcachefs: Array bounds fixes

2023-10-22T21:10:12+00:00

It's no longer legal to use a zero size array as a flexible array member - this causes UBSAN to complain. This patch switches our zero size arrays to normal flexible array members when possible, and inserts casts in other places (e.g. where we use the zero size array as a marker partway through an array).
