Hi!
On 4.15-rc1, I get the following failure:
BTRFS critical (device sda1): corrupt leaf: root=1 block=3820662898688
slot=43 ino=35691 file_offset=0, invalid ram_bytes for uncompressed inline
extent, have 134 expect 281474976710677
Repeatable every boot attempt. 4.14 and earlier boot fine; btrfs check
(progs 4.13.3) doesn't find any badness either.

By a quick look at suspiciously large number
hex(281474976710677) = 0x1000000000015
may be a bitflip, but 0x15 does not match 134, so there could be
something else involved in the corruption.

The reason why you hit this on 4.15 is because this error is coming from the tree checker.
So how big is the file which inode 35691 represents?
So the check which fails is:
if (item_size != BTRFS_FILE_EXTENT_INLINE_DATA_START +
btrfs_file_extent_ram_bytes(leaf, fi)) {
file_extent_err(root, leaf, slot,
"invalid ram_bytes for uncompressed inline extent, have %u expect %llu",
item_size, BTRFS_FILE_EXTENT_INLINE_DATA_START +
btrfs_file_extent_ram_bytes(leaf, fi));
return -EUCLEAN;
}
BTRFS_FILE_EXTENT_INLINE_DATA_START is 21 based on pahole's output:
struct btrfs_file_extent_item {
__le64 generation; /* 0 8 */
__le64 ram_bytes; /* 8 8 */
__u8 compression; /* 16 1 */
__u8 encryption; /* 17 1 */
__le16 other_encoding; /* 18 2 */
__u8 type; /* 20 1 */
__le64 disk_bytenr; /* 21 8 */
__le64 disk_num_bytes; /* 29 8 */
__le64 offset; /* 37 8 */
__le64 num_bytes; /* 45 8 */
/* size: 53, cachelines: 1, members: 10 */
/* last cacheline: 53 bytes */
};
The inline extent size is 113 so 21 + 113 should is 134 which equals to what we expect. However,
the printing code uses btrfs_file_extent_inline_len and the tree-checker code uses directly the
ram bytes. And this function does the correct thing according to whether the file is compressed or not.
So Qu, perhaps the code needs to be changed or is this a genuine bug ?

I guess the code here is :
void btrfs_mark_buffer_dirty(struct extent_buffer *buf)
{
#ifdef CONFIG_BTRFS_FS_CHECK_INTEGRITY
if (btrfs_header_level(buf) == 0 && btrfs_check_leaf(root, buf)) {
btrfs_print_leaf(buf);
ASSERT(0);
}
#endif
}
There was an issue with the leaf checker being used in btrfs_mark_buffer_dirty, Qu is this yet another instance of that ?

The problem is, the reporter is using CONFIG_BTRFS_FS_CHECK_INTEGRITY,
which will call btrfs_check_leaf() every time btrfs_mark_buffer_dirty().
However just as explained in the fixing patch:
https://patchwork.kernel.org/patch/10047489/
The timing of call btrfs_mark_buffer_dirty() is not right, one of the
most obvious place is for EXTENT_DATA.
So please apply the above patch to see if it solves the problem.
Thanks,

That's a known bug, fixed by that patch which is not merged yet.
