File xfsprogs-repair-Fix-root-inode-s-parent-when-it-s-bogus-f.patch of Package xfsprogs.14514
From 77b3425e3bee68e92eabdd1d01bc26853acc22b9 Mon Sep 17 00:00:00 2001 From: Marco Benatto <mbenatto@redhat.com> Date: Thu, 21 Jun 2018 19:46:24 -0500 Subject: [PATCH] xfs_repair: Fix root inode's parent when it's bogus for sf directory Git-commit: 77b3425e3bee68e92eabdd1d01bc26853acc22b9 Patch-mainline: v4.17.0-rc1 References: bsc#1119063 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 <mbenatto@redhat.com> Reviewed-by: Eric Sandeen <sandeen@redhat.com> Signed-off-by: Eric Sandeen <sandeen@sandeen.net> Acked-by: Anthony Iliopoulos <ailiopoulos@suse.com> --- repair/dir2.c | 4 +++- 1 file changed, 3 insertions(+), 1 deletion(-) diff --git a/repair/dir2.c b/repair/dir2.c index e162d2b8..225f9266 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 ", "), -- 2.16.4
