Hi Bruce,
Thanks for the quick reply. We are almost of the time working on devel
LFS/BLFS version
Here are the elements:
e2fsprogs version 1.44.0
cat /usr/include/ext2fs/ext2_ext_attr.h | grep e_value
__u16 e_value_offs; /* offset in disk block of value */
__u32 e_value_inum; /* inode in which the value is
stored */
__u32 e_value_size; /* size of attribute value */
i don' t have the file you mentioned __32 e-value_block.
Something wrong with my e2fsprogs version? Should i upgrade to the
1.44.1 version which came in the change log the 23/03/2018 or is it
wiser to stay on the stable lfs 1.43.9 ?
Please do not top post.
I do not know why you are having the problem.
struct ext2_ext_attr_entry {
__u8 e_name_len; /* length of name */
__u8 e_name_index; /* attribute name index */
__u16 e_value_offs; /* offset in disk block of value */
__u32 e_value_block; /* disk block attribute is stored on (n/i) */
__u32 e_value_size; /* size of attribute value */
__u32 e_hash; /* hash value of name and value */
#if 0
char e_name[0]; /* attribute name */
#endif
};
That is from EXT2FS Library version 1.43.8, 1-Jan-2018
Between 1.43.9 and 1.44.1, e_value_block was replaced by
e_value_inum in that structure!
Possibly, s/block/inum/ in that field of btrfs-progs - but probably
best to talk to btrfs upstream.
Good catch ken. We can add a pretty simple sed to change e_value_block
to e_value_inum, but I raised an issue with btrfs. Lets see what they
do in the next couple of days:
https://github.com/kdave/btrfs-progs/issues/121
Got an immediate answer.
- if (entry->e_value_block != 0 || value_size > size ||
- entry->e_value_offs + value_size > size)
+ if (value_size > size || entry->e_value_offs + value_size > size)
So they will just remove 'entry->e_value_block != 0 ||'
For now, use
sed -i '/e_value_block/s/entry->e_value_block != 0 ||//' \
convert/source-ext2.c
