>From U-Boot commit: | commit b5bbac1a9b07016602559ff483df265fef6c1f83 | Author: Ionut Nicu <ioan.nicu.ext@xxxxxxx> | Date: Mon Jan 13 12:00:08 2014 +0100 | | 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. | | Signed-off-by: Ionut Nicu <ioan.nicu.ext@xxxxxxx> | Signed-off-by: Mathias Rulf <mathias.rulf@xxxxxxx> Signed-off-by: Sascha Hauer <s.hauer@xxxxxxxxxxxxxx> --- fs/ext4/ext4_common.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/fs/ext4/ext4_common.c b/fs/ext4/ext4_common.c index ceb965f..5bff868 100644 --- a/fs/ext4/ext4_common.c +++ b/fs/ext4/ext4_common.c @@ -60,7 +60,7 @@ static struct ext4_extent_header *ext4fs_get_extent_block(struct ext2_data *data i++; if (i >= le32_to_cpu(ext_block->eh_entries)) break; - } while (fileblock > le32_to_cpu(index[i].ei_block)); + } while (fileblock >= le32_to_cpu(index[i].ei_block)); if (--i < 0) return 0; -- 2.0.1 _______________________________________________ barebox mailing list barebox@xxxxxxxxxxxxxxxxxxx http://lists.infradead.org/mailman/listinfo/barebox
