Subject: [f2fs-dev] f2fs_symlink bug
Date: Mon, 12 Aug 2019 20:01:11 +0800 [thread overview]
Message-ID: <3bc8584e-651c-9578-c25a-40c60b5cfbdb@huawei.com> (raw)
Hi Jaegeuk,
In por_fsstress testcase, fsck reports below inconsistent status, I found one
path can cause this case.
[FIX] (fsck_chk_inode_blk:1002) --> Symlink: recover 0x1425 with i_size=4096
[ASSERT] (fsck_chk_inode_blk:1030) --> ino: 0x1425 chksum:0x6983d47, but
calculated one is: 0xdb284b35
[FIX] (fsck_chk_inode_blk:1036) --> ino: 0x1425 recover, i_inode_checksum=
0x6983d47 -> 0xdb284b35
- f2fs_symlink
- page_symlink failed -> f2fs_write_failed() will truncate size to zero
- f2fs_unlink failed -> symlink inode w/o data will remain in fs
Not sure, but one choice of fix is to treat symlink as fs meta like we did for
directory, so that checkpoint can take care of all data/node of symlink, any
thoughts?
