Subject: [PATCH 2/2] ext4fs: fix "invalid extent block" error
|
|
|
|
For files where we actually have extent indexes following
|
|
an extent header (ext_block->eh_depth != 0), the do/while
|
|
loop from ext4fs_get_extent_block() does not select the
|
|
proper extent index structure.
|
|
|
|
For example, if we have:
|
|
|
|
ext_block->eh_depth = 1
|
|
ext_block->eh_entries = 1
|
|
fileblock = 0
|
|
index[0].ei_block = 0
|
|
|
|
the do/while loop will exit with i set to 0 and the
|
|
ext4fs_get_extent_block() function will return 0, even if
|
|
there was a valid extent index structure following the
|
|
header.
