The current code was erroneously checking for root_level > BTRFS_MAX_LEVEL. If we had a root_level of 8 then the check won't trigger and we could potentially hit a buffer overflow. The correct check should be root_level >= BTRFS_MAX_LEVEL .

Now use the btrfs_check_rw_degradable() to check if we can mount in the degraded mode. With this patch, we can mount in the following case: # mkfs.btrfs -f -m raid1 -d single /dev/sdb /dev/sdc # wipefs -a /dev/sdc # mount /dev/sdb /mnt/btrfs -o degraded As the single data chunk is only on sdb, so it's OK to mount as degraded, as missing one device is OK for RAID1. But still fail in the following case as expected: # mkfs.btrfs -f -m raid1 -d single /dev/sdb /dev/sdc # wipefs -a /dev/sdb # mount /dev/sdc /mnt/btrfs -o degraded As the data chunk is only in sdb, so it's not OK to mount it as degraded.

Introduce a new function, btrfs_check_rw_degradable(), to check if all chunks in btrfs is OK for degraded rw mount. It provides the new basis for accurate btrfs mount/remount and even runtime degraded mount check other than old one-size-fit-all method. Btrfs currently uses num_tolerated_disk_barrier_failures to do global check for tolerated missing device. Although the one-size-fit-all solution is quite safe, it's too strict if data and metadata has different duplication level. For example, if one use Single data and RAID1 metadata for 2 disks, it means any missing device will make the fs unable to be degraded mounted. But in fact, some times all single chunks may be in the existing device and in that case, we should allow it to be rw degraded mounted. Such case can be easily reproduced using the following script: # mkfs.btrfs -f -m raid1 -d sing /dev/sdb /dev/sdc # wipefs -f /dev/sdc # mount /dev/sdb -o degraded,rw If using btrfs-debug-tree to check /dev/sdb, one should find that the data chunk is only in sdb, so in fact it should allow degraded mount. This patchset will introduce a new per-chunk degradable check for btrfs, allow above case to succeed, and it's quite small anyway.

When btrfs fails the checksum check, it'll fill the whole page with "1". However, if %csum_expected is 0 (which means there is no checksum), then for some unknown reason, we just pretend that the read is correct, so userspace would be confused about the dilemma that read is successful but getting a page with all content being "1". This can happen due to a bug in btrfs-convert. This fixes it by always returning errors if checksum doesn't match.

In btrfs_full_stripe_len/btrfs_is_parity_mirror we have similar code which gets the chunk map for a particular range via get_chunk_map. However, get_chunk_map can return an ERR_PTR value and while the 2 callers do catch this with a WARN_ON they then proceed to indiscriminately dereference the extent map. This of course leads to a crash. Fix the offenders by making the dereference conditional on IS_ERR.

Many commits ago the data space_info in alloc_data_chunk_ondemand used to be acquired from the inode. At that point commit 33b4d47f ("Btrfs: deal with NULL space info") got introduced to deal with spurios cases where the space info could be null, following a rebalance. Nowadays, however, the space info is referenced directly from the btrfs_fs_info struct which is initialised at filesystem mount time. This makes the null checks redundant, so remove them.

Several distributions mount the "proper root" as ro during initrd and then remount it as rw before pivot_root(2). Thus, if a rescan had been aborted by a previous shutdown, the rescan would never be resumed. This issue would manifest itself as several btrfs ioctl(2)s causing the entire machine to hang when btrfs_qgroup_wait_for_completion was hit (due to the fs_info->qgroup_rescan_running flag being set but the rescan itself not being resumed). Notably, Docker's btrfs storage driver makes regular use of BTRFS_QUOTA_CTL_DISABLE and BTRFS_IOC_QUOTA_RESCAN_WAIT (causing this problem to be manifested on boot for some machines).

It's been known for a while that the use of multiple lists that are periodically merged was an algorithmic problem within btrfs. There are several workloads that don't complete in any reasonable amount of time (e.g. btrfs/130) and others that cause soft lockups. The solution is to use a set of rbtrees that do insertion merging for both indirect and direct refs, with the former converting refs into the latter. The result is a btrfs/130 workload that used to take several hours now takes about half of that. This runtime still isn't acceptable and a future patch will address that by moving the rbtrees higher in the stack so the lookups can be shared across multiple calls to find_parent_nodes.

Commit afce772e ("btrfs: fix check_shared for fiemap ioctl") added the ref_tree code in backref.c to reduce backref searching for shared extents under the FIEMAP ioctl. This code will not be compatible with the upcoming rbtree changes for improved backref searching, so this patch removes the ref_tree code. The rbtree changes will provide the equivalent functionality for FIEMAP. The above commit also introduced transaction semantics around calls to btrfs_check_shared() in order to accurately account for delayed refs. This functionality needs to be retained, so a complete revert of the above commit is not desirable. This patch therefore removes the ref_tree portion of the commit as above, however it does not remove the transaction portion.

We typically use __ to indicate a helper routine that shouldn't be called directly without understanding the proper context required to do so. We use static functions to indicate that a function is private to a particular C file. The backref code uses static function and __ prefixes on nearly everything, which makes the code difficult to read and establishes a pattern for future code that shouldn't be followed. This patch drops all the unnecessary prefixes. Signed-off-by: NJeff Mahoney <jeffm@suse.com> Signed-off-by: NDavid Sterba <dsterba@suse.com>
