Happy new year! The following changes since commit 453f5db0619e2ad64076aab16ff5a00e0f7c53a2: Merge tag 'trace-v6.7-rc7' of git://git.kernel.org/pub/scm/linux/kernel/git/trace/linux-trace (2023-12-30 11:37:35 -0800) are available in the Git repository at: https://evilpiepirate.org/git/bcachefs.git tags/bcachefs-2024-01-01 for you to fetch changes up to 0d72ab35a925d66b044cb62b709e53141c3f0143: bcachefs: make RO snapshots actually RO (2024-01-01 11:47:07 -0500) ---------------------------------------------------------------- More bcachefs bugfixes for 6.7, and forwards compatibility work: - fix for a nasty extents + snapshot interaction, reported when reflink of a snapshotted file wouldn't complete but turned out to be a more general bug - fix for an invalid free in dio write path when iov vector was longer than our inline vecotr - fix for a buffer overflow in the nocow write path - BCH_REPLICAS_MAX doesn't actually limit the number of pointers in an extent when cached pointers are included - RO snapshots are actually RO now - And, a new superblock section to avoid future breakage when the disk space acounting rewrite rolls out: the new superblock section describes versions that need work to downgrade, where the work required is a list of recovery passes and errors to silently fix. ---------------------------------------------------------------- Kent Overstreet (13): bcachefs: Fix extents iteration + snapshots interaction bcachefs: fix invalid free in dio write path bcachefs: fix setting version_upgrade_complete bcachefs: Factor out darray resize slowpath bcachefs: Switch darray to kvmalloc() bcachefs: DARRAY_PREALLOCATED() bcachefs: fix buffer overflow in nocow write path bcachefs: move BCH_SB_ERRS() to sb-errors_types.h bcachefs: prt_bitflags_vector() bcachefs: Add persistent identifiers for recovery passes bcachefs: bch_sb.recovery_passes_required bcachefs: bch_sb_field_downgrade bcachefs: make RO snapshots actually RO fs/bcachefs/Makefile | 2 + fs/bcachefs/acl.c | 3 +- fs/bcachefs/bcachefs.h | 1 + fs/bcachefs/bcachefs_format.h | 51 ++++++--- fs/bcachefs/btree_iter.c | 35 ++++-- fs/bcachefs/darray.c | 24 ++++ fs/bcachefs/darray.h | 48 +++++--- fs/bcachefs/errcode.h | 3 + fs/bcachefs/error.c | 3 + fs/bcachefs/fs-io-direct.c | 13 +-- fs/bcachefs/fs-ioctl.c | 12 +- fs/bcachefs/fs.c | 38 ++++++- fs/bcachefs/io_write.c | 82 +++++++------- fs/bcachefs/printbuf.c | 22 ++++ fs/bcachefs/printbuf.h | 2 + fs/bcachefs/recovery.c | 137 +++++++++++++++++++---- fs/bcachefs/recovery.h | 3 + fs/bcachefs/recovery_types.h | 86 ++++++++------ fs/bcachefs/sb-clean.c | 2 - fs/bcachefs/sb-downgrade.c | 188 +++++++++++++++++++++++++++++++ fs/bcachefs/sb-downgrade.h | 10 ++ fs/bcachefs/sb-errors.c | 6 +- fs/bcachefs/sb-errors.h | 253 +----------------------------------------- fs/bcachefs/sb-errors_types.h | 253 ++++++++++++++++++++++++++++++++++++++++++ fs/bcachefs/subvolume.c | 18 +++ fs/bcachefs/subvolume.h | 3 + fs/bcachefs/super-io.c | 86 +++++++++++++- fs/bcachefs/super-io.h | 12 +- fs/bcachefs/util.h | 1 + fs/bcachefs/xattr.c | 3 +- 30 files changed, 977 insertions(+), 423 deletions(-) create mode 100644 fs/bcachefs/darray.c create mode 100644 fs/bcachefs/sb-downgrade.c create mode 100644 fs/bcachefs/sb-downgrade.h
