sbi->s_firstdatazone in complete_read_super sbi->s_firstinodezone is initialized to 2 and sbi->s_firstdatazone is read from sbd. There's no guarantee that sbi->s_firstdatazone must bigger than sbi->s_firstinodezone. If sbi->s_firstdatazone less than 2, the filesystem can still be mounted unexpetly. At this point, sbi->s_ninodes flip to very large value and this filesystem is broken. We can observe this by executing 'df' command. When we execute, we will get an error message: "sysv_count_free_inodes: unable to read inode table" Link: https://lkml.kernel.org/r/20220330104215.530223-1-liushixin2@huawei.com Signed-off-by: Liu Shixin Reviewed-by: Christoph Hellwig Signed-off-by: Andrew Morton fs/sysv/super.c | 4 +++- 1 file changed, 3 insertions(+), 1 deletion(-) accumulated error probability: 0.00 culprit signature: 1cc3d3091037d5c35b7da453562b51f06b3200d2a54fa1de9cdacf3d687f47cd parent signature: 85fe3e3c720828261ffdf7d632f909236b958710a5302acf0d607445b32b14f4 revisions tested: 29, total time: 5h56m40.993542277s (build: 3h2m20.192962233s, test: 2h33m15.13738766s) first bad commit: f6e2c20ca7604e6a267c93a511d19dda72573be1 fs: sysv: check sbi->s_firstdatazone in complete_read_super recipients (to): ["akpm@linux-foundation.org" "hch@lst.de" "liushixin2@huawei.com"] recipients (cc): [] crash: WARNING in invalidate_bh_lru oldfs: cannot read superblock ------------[ cut here ]------------ VFS: brelse: Trying to free free buffer WARNING: CPU: 1 PID: 1998 at fs/buffer.c:1145 __brelse fs/buffer.c:1145 [inline] WARNING: CPU: 1 PID: 1998 at fs/buffer.c:1145 __brelse fs/buffer.c:1139 [inline] WARNING: CPU: 1 PID: 1998 at fs/buffer.c:1145 brelse include/linux/buffer_head.h:290 [inline] WARNING: CPU: 1 PID: 1998 at fs/buffer.c:1145 __invalidate_bh_lrus fs/buffer.c:1391 [inline] WARNING: CPU: 1 PID: 1998 at fs/buffer.c:1145 invalidate_bh_lru+0x5e/0x90 fs/buffer.c:1404 Modules linked in: CPU: 1 PID: 1998 Comm: syz-executor.0 Not tainted 5.18.0-rc4-syzkaller #0 Hardware name: Google Google Compute Engine/Google Compute Engine, BIOS Google 07/12/2023 RIP: 0010:__brelse fs/buffer.c:1145 [inline] RIP: 0010:__brelse fs/buffer.c:1139 [inline] RIP: 0010:brelse include/linux/buffer_head.h:290 [inline] RIP: 0010:__invalidate_bh_lrus fs/buffer.c:1391 [inline] RIP: 0010:invalidate_bh_lru+0x5e/0x90 fs/buffer.c:1404 Code: c7 03 00 00 00 00 48 83 c3 08 48 39 eb 74 2d 48 8b 03 48 85 c0 74 e8 8b 50 60 85 d2 75 dd 48 c7 c7 00 35 e4 82 e8 69 7f fa 00 <0f> 0b 48 c7 03 00 00 00 00 48 83 c3 08 48 39 eb 75 d3 bf 01 00 00 RSP: 0018:ffffc90001c2fbf8 EFLAGS: 00010086 RAX: 0000000000000000 RBX: ffff88813bd29600 RCX: 0000000000000000 RDX: 0000000000000003 RSI: ffffffff82d89710 RDI: 00000000ffffffff RBP: ffff88813bd29680 R08: 0000000000000000 R09: ffffffff83294160 R10: ffffc90001c2fa18 R11: ffffffff833741a8 R12: 0000000000000202 R13: ffffffff812e1210 R14: 0000000000000001 R15: 0000000000000000 FS: 00007f02d22856c0(0000) GS:ffff88813bd00000(0000) knlGS:0000000000000000 CS: 0010 DS: 0000 ES: 0000 CR0: 0000000080050033 CR2: 0000560657bd0128 CR3: 0000000107fd7000 CR4: 00000000003506e0 DR0: 0000000000000000 DR1: 0000000000000000 DR2: 0000000000000000 DR3: 0000000000000000 DR6: 00000000fffe0ff0 DR7: 0000000000000400 Call Trace: smp_call_function_many_cond+0x159/0x5b0 kernel/smp.c:960 on_each_cpu_cond_mask+0x3b/0x70 kernel/smp.c:1135 invalidate_bdev+0x1e/0x40 block/bdev.c:86 invalidate_disk+0x18/0x60 block/genhd.c:676 __loop_clr_fd+0x235/0x3b0 drivers/block/loop.c:1147 loop_clr_fd drivers/block/loop.c:1230 [inline] lo_ioctl+0x201/0x840 drivers/block/loop.c:1556 blkdev_ioctl+0x131/0x270 block/ioctl.c:588 vfs_ioctl fs/ioctl.c:51 [inline] __do_sys_ioctl fs/ioctl.c:870 [inline] __se_sys_ioctl fs/ioctl.c:856 [inline] __x64_sys_ioctl+0x84/0xc0 fs/ioctl.c:856 do_syscall_x64 arch/x86/entry/common.c:50 [inline] do_syscall_64+0x38/0x80 arch/x86/entry/common.c:80 entry_SYSCALL_64_after_hwframe+0x44/0xae RIP: 0033:0x7f02d147c88b Code: 00 48 89 44 24 18 31 c0 48 8d 44 24 60 c7 04 24 10 00 00 00 48 89 44 24 08 48 8d 44 24 20 48 89 44 24 10 b8 10 00 00 00 0f 05 <89> c2 3d 00 f0 ff ff 77 1c 48 8b 44 24 18 64 48 2b 04 25 28 00 00 RSP: 002b:00007f02d2284e90 EFLAGS: 00000246 ORIG_RAX: 0000000000000010 RAX: ffffffffffffffda RBX: ffffffffffffffff RCX: 00007f02d147c88b RDX: 0000000000000000 RSI: 0000000000004c01 RDI: 0000000000000004 RBP: 0000000000000016 R08: 00007f02d2284f80 R09: 0000000000008003 R10: 0000000000008003 R11: 0000000000000246 R12: 0000000000000004 R13: 00007f02d2284f40 R14: 0000000000009dfc R15: 0000000020000000
