2024-09-21bcachefs: bch2_dev_remove_alloc() -> alloc_background.cKent Overstreet
Signed-off-by: Kent Overstreet <kent.overstreet@linux.dev>
2024-09-21bcachefs: Move tabstop setup to bch2_dev_usage_to_text()Kent Overstreet
No reason for it not to be where it's needed. Signed-off-by: Kent Overstreet <kent.overstreet@linux.dev>
2024-09-21bcachefs: Options for recovery_passes, recovery_passes_excludeKent Overstreet
This adds mount options for specifying recovery passes to run, or exclude; the immediate need for this is that backpointers fsck is having trouble completing, so we need a way to skip it. Signed-off-by: Kent Overstreet <kent.overstreet@linux.dev>
2024-09-21bcachefs: Use mm_account_reclaimed_pages() when freeing btree nodesKent Overstreet
When freeing in a shrinker callback, we need to notify memory reclaim, so it knows forward progress has been made. Normally this is done in e.g. slab code, but we're not freeing through slab - or rather we are, but these allocations are big, and use the kmalloc_large() path. This is really a bug in the slub code, but we're working around it here for now. Signed-off-by: Kent Overstreet <kent.overstreet@linux.dev>
2024-09-21bcachefs: Use __GFP_ACCOUNT for reclaimable memoryKent Overstreet
Signed-off-by: Kent Overstreet <kent.overstreet@linux.dev>
2024-09-21bcachefs: Hook up RENAME_WHITEOUT in rename.Sasha Finkelstein
This is needed for overlayfs, which is used by container managers. Signed-off-by: Sasha Finkelstein <fnkl.kernel@gmail.com> Signed-off-by: Kent Overstreet <kent.overstreet@linux.dev>
2024-09-21bcachefs: rebalance writes use BCH_WRITE_ONLY_SPECIFIED_DEVSKent Overstreet
this was an oversight: rebalance is moving data to a specific device, so we don't want it falling back to the full filesystem Signed-off-by: Kent Overstreet <kent.overstreet@linux.dev>
2024-09-21bcachefs: BCH_WRITE_ALLOC_NOWAIT no longer applies to open bucket allocationKent Overstreet
rebalance writes must be BCH_WRITE_ALLOC_NOWAIT because they don't allocate from the full filesystem - but we don't want spurious allocation failures due to open buckets. Signed-off-by: Kent Overstreet <kent.overstreet@linux.dev>
2024-09-21bcachefs: fix prototype to bch2_alloc_sectors_start_trans()Kent Overstreet

2024-09-21bcachefs: kill redundant is_vmalloc_addr()Kent Overstreet

2024-09-21bcachefs: convert __bch2_encrypt_bio() to darrayKent Overstreet
like the previous patch, kill use of bare arrays; the encryption code likes to work in big batches, so this is a small performance improvement. Signed-off-by: Kent Overstreet <kent.overstreet@linux.dev>
2024-09-21bcachefs: do_encrypt() now handles allocation failuresKent Overstreet
convert to darray, and add a fallback when allocation fails Signed-off-by: Kent Overstreet <kent.overstreet@linux.dev>
2024-09-21bcachefs: Add pinned to btree cache not freed countersKent Overstreet
Signed-off-by: Kent Overstreet <kent.overstreet@linux.dev>
2024-09-09bcachefs: Annotate bch_replicas_entry_{v0,v1} with __counted_by()Thorsten Blum
Add the __counted_by compiler attribute to the flexible array members devs to improve access bounds-checking via CONFIG_UBSAN_BOUNDS and CONFIG_FORTIFY_SOURCE. Increment nr_devs before adding a new device to the devs array and adjust the array indexes accordingly. Add a helper macro for adding a new device. In bch2_journal_read(), explicitly set nr_devs to 0. Signed-off-by: Thorsten Blum <thorsten.blum@toblux.com> Signed-off-by: Kent Overstreet <kent.overstreet@linux.dev>
2024-09-09bcachefs: support idmap mountsHongbo Li
We enable idmapped mounts for bcachefs. Here, we just pass down the user_namespace argument from the VFS methods to the relevant helpers. The idmap test in bcachefs is as following: ``` 1. losetup /dev/loop1 bcachefs.img 2. ./bcachefs format /dev/loop1 3. mount -t bcachefs /dev/loop1 /mnt/bcachefs/ 4. ./mount-idmapped --map-mount b:0:1000:1 /mnt/bcachefs /mnt/idmapped1/ ll /mnt/bcachefs total 2 drwx------. 2 root root 0 Jun 14 14:10 lost+found -rw-r--r--. 1 root root 1945 Jun 14 14:12 profile ll /mnt/idmapped1/ total 2 drwx------. 2 1000 1000 0 Jun 14 14:10 lost+found -rw-r--r--. 1 1000 1000 1945 Jun 14 14:12 profile Signed-off-by: Hongbo Li <lihongbo22@huawei.com> Reviewed-by: Christian Brauner <brauner@kernel.org> Signed-off-by: Kent Overstreet <kent.overstreet@linux.dev>
2024-09-09bcachefs: Annotate struct bch_xattr with __counted_by()Thorsten Blum

2024-09-09bcachefs: Convert to use jiffies macrosChen Yufan
Use jiffies macros instead of using jiffies directly to handle wraparound. Signed-off-by: Chen Yufan <chenyufan@vivo.com> Signed-off-by: Kent Overstreet <kent.overstreet@linux.dev>
2024-09-09bcachefs: Refactor bch2_bset_fix_lookup_tableAlan Huang
bch2_bset_fix_lookup_table is too complicated to be easily understood, the comment "l now > where" there is also incorrect when where == t->end_offset. This patch therefore refactor the function, the idea is that when where >= rw_aux_tree(b, t)[t->size - 1].offset, we don't need to adjust the rw aux tree.

2024-09-09bcachefs: Assert that we don't lock nodes when !trans->lockedKent Overstreet
We rely on the trans->locked to know if a trans has nodes locked for assertions about deadlocks; there can't be more than one trans in the same process that is locked. Signed-off-by: Kent Overstreet <kent.overstreet@linux.dev>
2024-09-09bcachefs: Do not check folio_has_private()Matthew Wilcox (Oracle)
folio_has_private() is an attractive nuisance; filesystem authors generally don't realise that it actually checks two flags (one of which is never set by bcachefs). There's no need to check the private flag at all; for folios owned by bcachefs, we know that folio->private is NULL when the private flag is clear and non-NULL when the private flag is set.

2024-09-09bcachefs: Drop memalloc_nofs_save() in bch2_btree_node_mem_alloc()Kent Overstreet
It's really not needed: the only locks used here are the btree cache lock, which we drop for GFP_WAIT allocations, and btree node locks - but we also drop those for GFP_WAIT allocations. Signed-off-by: Kent Overstreet <kent.overstreet@linux.dev>
2024-09-09bcachefs: Simplify bch2_xattr_emit() implementationYouling Tang
Use helper functions to make code more readable. Similar to commit a5488f29835c ("fs: simplify ->listxattr() implementation") Signed-off-by: Youling Tang <tangyouling@kylinos.cn> Signed-off-by: Kent Overstreet <kent.overstreet@linux.dev>
2024-09-09bcachefs: drop unused posix acl handlersYouling Tang
Remove struct nop_posix_acl_{access,default} for bcachefs filesystem that don't depend on the xattr handler in their inode->i_op->listxattr() method in any way. There's nothing more to do than to simply remove the handler. It's been effectively unused ever since we introduced the new posix acl api. See [1] for details.

2024-09-09bcachefs: Remove the prev array stuffAlan Huang
After reducing the search range when building the aux tree, the prev array stuff is no longer useful, so remove it. Signed-off-by: Alan Huang <mmpgouride@gmail.com> Signed-off-by: Kent Overstreet <kent.overstreet@linux.dev>
2024-09-09bcachefs: Minimize the search range used to calculate the mantissaAlan Huang
When the search key's mantissa is larger than the node i's, we know that the search key is larger than the first key of the cacheline corresponding to node i, so that when we are calculating the mantissa of right side nodes of node i, the left side of the search range can be the first key of node i. Once the search range is minimized, the mantissa we are calculating can have more useful bits, thus reduce the slow path comparison. Besides, we can now remove all the prev array stuff.
