As Jungyeon reported in bugzilla: https://bugzilla.kernel.org/show_bug.cgi?id=203227 - Overview When mounting the attached crafted image, following errors are reported. Additionally, it hangs on sync after trying to mount it. The image is intentionally fuzzed from a normal f2fs image for testing. Compile options for F2FS are as follows. CONFIG_F2FS_FS=y CONFIG_F2FS_STAT_FS=y CONFIG_F2FS_FS_XATTR=y CONFIG_F2FS_FS_POSIX_ACL=y CONFIG_F2FS_CHECK_FS=y - Reproduces mkdir test mount -t f2fs tmp.img test sync - Messages kernel BUG at fs/f2fs/recovery.c:549! RIP: 0010:recover_data+0x167a/0x1780 Call Trace: f2fs_recover_fsync_data+0x613/0x710 f2fs_fill_super+0x1043/0x1aa0 mount_bdev+0x16d/0x1a0 mount_fs+0x4a/0x170 vfs_kern_mount+0x5d/0x100 do_mount+0x200/0xcf0 ksys_mount+0x79/0xc0 __x64_sys_mount+0x1c/0x20 do_syscall_64+0x43/0xf0 entry_SYSCALL_64_after_hwframe+0x44/0xa9 During recovery, if ofs_of_node is inconsistent in between recovered node page and original checkpointed node page, let's just fail recovery instead of making kernel panic.
