xfs_repair: Fix root inode's parent when it's bogus for sf directory Currently when root inode is in short-form and its parent ino has an invalid value, process_sf_dir2() ends up not fixing it, because if verify_inum() fails we never get to the next case which would fix the root inode's parent pointer. This behavior triggers the following assert on process_dir2(): ASSERT((ino != mp->m_sb.sb_rootino && ino != *parent) || (ino == mp->m_sb.sb_rootino && (ino == *parent || need_root_dotdot == 1))); This patch fixes this behavior by making sure we always properly handle rootino parent pointer in process_sf_dir2() Signed-off-by: Marco Benatto Reviewed-by: Eric Sandeen --- Note: reviewed but not yet merged upstream repair/dir2.c | 4 +++- 1 file changed, 3 insertions(+), 1 deletion(-) diff --git a/repair/dir2.c b/repair/dir2.c index e162d2b..225f926 100644 --- a/repair/dir2.c +++ b/repair/dir2.c @@ -495,8 +495,10 @@ _("corrected entry offsets in directory %" PRIu64 "\n"), /* * if parent entry is bogus, null it out. we'll fix it later . + * If the validation fails for the root inode we fix it in + * the next else case. */ - if (verify_inum(mp, *parent)) { + if (verify_inum(mp, *parent) && ino != mp->m_sb.sb_rootino) { do_warn( _("bogus .. inode number (%" PRIu64 ") in directory inode %" PRIu64 ", "), -- 2.9.5 -- To unsubscribe from this list: send the line "unsubscribe linux-xfs" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
