| 3 | I'm using the -d option of mke2fs to construct a filesystem, I'm seeing | 16 | Richard Purdie reports that libext2fs doesn't sort attribute keys in |
| 4 | that some xattrs are being corrupted. The filesystem builds with no | 17 | the xattr block correctly, causing the kernel to return -ENODATA when |
| 5 | errors but when mounted by the kernel, I see errors like "security.ima: | 18 | querying attributes that should be there. Therefore, sort attributes |
| 6 | No such attribute". The strace from such a failure is: | 19 | so that whatever ends up in the xattr block is sorted according to |
| 20 | what the kernel expects. | ||

| 24 | so the attribute is there but the kernel gives ENODATA when trying | ||
| 25 | to read it. | ||
| 26 | |||
| 27 | http://www.nongnu.org/ext2-doc/ext2.html#CONTRIB-EXTENDED-ATTRIBUTES co | ||
| 28 | ntains the small snippet that " The entry descriptors are sorted by | ||
| 29 | attribute name, so that two extended attribute blocks can be compared | ||
| 30 | efficiently. ". It doesn't specify what kind of sort. | ||
| 31 | |||
| 32 | Looking at ext2fs, there is some sorting code through the qsort call | ||
| 33 | using attr_compare() but it doesn't match what the kernel is doing in | ||
| 34 | ext4_xattr_find_entry(). | ||
| 35 | |||
| 36 | This patch fixes the problem. | ||
