2025-03-24bcachefs: bch2_write_prep_encoded_data() now returns errcodeKent Overstreet
Prep work for killing off EIO and replacing them with proper private error codes. Signed-off-by: Kent Overstreet <kent.overstreet@linux.dev>
2025-03-24bcachefs: Simplify bch2_write_op_error()Kent Overstreet
There's no reason for the caller to do the actual logging, it's all done the same. Signed-off-by: Kent Overstreet <kent.overstreet@linux.dev>
2025-03-24bcachefs: Fix block/btree node size defaultsKent Overstreet
We're fixing option parsing in userspace, it now obeys OPT_SB_FIELD_SECTORS Signed-off-by: Kent Overstreet <kent.overstreet@linux.dev>
2025-03-24bcachefs: Add missing smp_rmb()Alan Huang
The smp_rmb() guarantees that reads from reservations.counter occur before accessing cur_entry_u64s. It's paired with the atomic64_try_cmpxchg in journal_entry_open. Signed-off-by: Alan Huang <mmpgouride@gmail.com> Signed-off-by: Kent Overstreet <kent.overstreet@linux.dev>
2025-03-24bcachefs: Kill JOURNAL_ERRORS()Kent Overstreet
Convert these to standard error codes, which means we can pass them outside the journal code, they're easier to pass to tracepoints, etc. Signed-off-by: Kent Overstreet <kent.overstreet@linux.dev>
2025-03-24bcachefs: Filesystem discard option now propagates to devicesKent Overstreet
the discard option is special, because it's both a filesystem and a device option. When set at the filesytsem level, it's supposed to propagate to (if set persistently via sysfs) or override (if non persistently as a mount option) the devices - that now works correctly. Signed-off-by: Kent Overstreet <kent.overstreet@linux.dev>
2025-03-24bcachefs: Device state is now a runtime optionKent Overstreet
Other options can normally be set at runtime via sysfs, no reason for this one not to be as well - it just doesn't support the degraded flags argument this way, that requires the ioctl. Signed-off-by: Kent Overstreet <kent.overstreet@linux.dev>

Signed-off-by: Kent Overstreet <kent.overstreet@linux.dev>
2025-03-24bcachefs: Device options now use standard sysfs codeKent Overstreet
Device options now use the common code for sysfs, and can superblock fields (in a struct bch_member). This replaces BCH_DEV_OPT_SETTERS(), which was weird and easy to miss. Signed-off-by: Kent Overstreet <kent.overstreet@linux.dev>
2025-03-24bcachefs: Kill BCH_DEV_OPT_SETTERS()Kent Overstreet
Previously, device options had their superblock option field listed separately, which was weird and easy to miss when defining options. Signed-off-by: Kent Overstreet <kent.overstreet@linux.dev>

2025-03-24bcachefs: Fix incorrect state countAlan Huang
atomic64_read(&j->seq) - j->seq_write_started == JOURNAL_STATE_BUF_NR is the condition in journal_entry_open where we return JOURNAL_ERR_max_open, so journal_cur_seq(j) - seq == JOURNAL_STATE_BUF_NR means that the buf corresponding to seq has started to write.

2025-03-24bcachefs: Fix btree iter flags in data moveKent Overstreet
Rebalance requires a not_extents iterator. This wasn't hit before because all_snapshots disableds is_extents on snapshots btrees - but has no effect on the reflink btree. Reported-by: Maël Kerbiriou <mael.kerbiriou@free.fr> Signed-off-by: Kent Overstreet <kent.overstreet@linux.dev>
2025-03-24bcachefs: Validate bch_sb.offset fieldKent Overstreet
This was missed - but it needs to be correct for the superblock recovery tool that scans the start and end of the device for backup superblocks: we don't want to pick up superblocks that belong to a different partition that starts at a different offset. Signed-off-by: Kent Overstreet <kent.overstreet@linux.dev>
2025-03-24bcachefs: bch2_sb_validate() doesn't need bch_sb_handleKent Overstreet

2025-03-24bcachefs: Improve can_write_extent()Kent Overstreet
This fixes another "rebalance spinning and doing no work" issue; rebalance was reading extents it wanted to move, but then failing in bch2_write() -> bch2_alloc_sectors_start() due to being unable to allocate sufficient replicas. This was triggered by a user playing with the durability settings, the foreground device was an NVME device with durability=2, and originally he'd set the background device to durability=2 as well, but changed it back to 1 (the default) after seeing IO errors. That meant that with replicas=2, we want to move data off the NVME device which satisfies that constraint, but with a single durability=1 device on the background target there's no way to move the extent to that target while satisfiying the "required replicas" constraint. The solution for now is for bch2_data_update_init() to check for this, and return an error - before kicking off the read. bch2_data_update_init() already had two different checks for "will we be able to write this extent", with partially duplicated code, so this patch combines and improves that logic. Additionally, we now always bail out and return an error if there's insufficient space on the destination target. Previously, we only did this for BCH_WRITE_alloc_nowait moves, because it might be the case that copygc just needs to free up space on the destination target. But we really shouldn't kick off a move if the destination is full, we can't currently distinguish between "really full" and "just need to wait for copygc", and if we are going to wait on copygc it'd be better to do that before kicking off the move. This will additionally fix "rebalance spinning" issues caused by a filesystem that has more data than can fit in background_target - which is a valid scenario, since we don't exclude foreground/cache devices when calculating filesystem capacity.

2025-03-24bcachefs: __bch2_read() now takes a btree_transKent Overstreet
Next patch will be checking if the extent we're reading from matches the IO failure we saw before marking the failure. For this to work, __bch2_read() needs to take the same transaction context that bch2_rbio_retry() uses to do that check. Signed-off-by: Kent Overstreet <kent.overstreet@linux.dev>
2025-03-24bcachefs: BCH_READ_data_update -> bch_read_bio.data_updateKent Overstreet
Read flags are codepath dependent and change as they're passed around, while the fields in rbio._state are mostly fixed properties of that particular object. Losing track of BCH_READ_data_update would be bad, and previously it was not obvious if it was always correctly set in the rbio, so this is a safety cleanup. Signed-off-by: Kent Overstreet <kent.overstreet@linux.dev>
2025-03-16bcachefs: Checksum errors get additional retriesKent Overstreet
It's possible for checksum errors to be transient - e.g. flakey controller or cable, thus we need additional retries (besides retrying from different replicas) before we can definitely return an error. This is particularly important for the next patch, which will allow the data move path to move extents with checksum errors - we don't want to accidentally introduce bitrot due to a transient error! - bch2_bkey_pick_read_device() is substantially reworked, and bch2_dev_io_failures is expanded to record more information about the type of failure (i.e. number of checksum errors). It now returns an error code that describes more precisely the reason for the failure - checksum error, io error, or offline device, instead of the previous generic "insufficient devices". This is important for the next patches that add poisoning, as we only want to poison extents when we've got real checksum errors (or perhaps IO errors?) - not because a device was offline. - Add a new option and superblock field for the number of checksum retries.

2025-03-16bcachefs: Return errors to top level bch2_rbio_retry()Kent Overstreet
Next patch will be adding an additional retry loop for checksum errors, so that we can rule out transient errors before marking an extent as poisoned. Prerequisite to this is returning errors to bch2_rbio_retry(); this will also let us add a "successful retry" message. Signed-off-by: Kent Overstreet <kent.overstreet@linux.dev>

2025-03-16bcachefs: Fix BCH_ERR_data_read_csum_err_maybe_userspace in retry pathKent Overstreet
When we do a read to a buffer that's mapped into userspace, it's possible to get a spurious checksum error if userspace was modified the buffer at the same time. When we retry those, they have to be bounced before we know definitively whether we're reading corrupt data. But the retry path propagates read flags differently, so needs special handling.
