category: bugfix
issue: #I6VAS0
CVE: NA
Signed-off-by: DongSenhao <dongsenhao2@huawei.com>
---------------------------------------
If the following process returns an error,
the quota inode, not the quota file, is damaged.
(fsck_chk_quota_node-->fsck_chk_node_blk-->sanity_check_nid)
The fsck does not have a process to rebuild the quota inode.
Because sanity_check_nid is not passed, fsck->nat_area_bitmap
can not be cleared, and then the NAT of quota will be nullify
during fix_nat_entries.
During the next fsck check, the quota inode check fails
because the address of the quota inode changes to 0.
In addition, in fsck_chk_quota_files-->f2fs_filesize_update,
data is written to address 0.
Therefore, when the quota inode is corrupted, we need to rebuild it.
