rawhide's init/nash segfaults in libblkid

rawhide's init/nash segfaults in libblkid

[Jim Meyering]

FYI, I've just filed this against the kernel:

  http://bugzilla.redhat.com/486997

Perhaps it should be reassigned to e2fsprogs...
---------

Normally I track rawhide pretty closely, but for the last few weeks
new kernels haven't booted on the system I use for that, so I stuck
with the most recent one that worked,

  2.6.29-0.74.rc3.git3.fc11.x86_64

However, now that there are 4 newer kernel images, none of which boots,
it's getting a little precarious, and I investigated.
Note: this is the first that failed to boot:

  2.6.29-0.99.rc4.git1.fc11.x86_64

The most recent, 2.6.29-0.131.rc5.git2.fc11.x86_64
also fails the same way, with a segfault from init/nash.

The traceback I saw had (from memory, sorry)

  glibc's strlen
  ...
  libblkid's blkid_verify
             blkid_get_dev
  nash...

I found that I could boot into any of the recent kernels,
only if I'd either disconnect /dev/hdb physically,
or if I had erased its partition table.  I did save a copy.

The partitions on /dev/hdb were of type ext4 and ext3:
Here's what parted said before I reformatted the xfs partition as ext4,
just to be sure xfs wasn't implicated:

  Model: ATA SAMSUNG HD501LJ (scsi)
  Disk /dev/sdb: 976773168s
  Sector size (logical/physical): 512B/512B
  Partition Table: msdos

  Number  Start       End         Size        Type      File system  Flags
   1      32s         390625279s  390625248s  primary   ext3         boot
   2      390625280s  488282111s  97656832s   primary   ext3
   3      488282112s  625000447s  136718336s  extended
   5      488282144s  585938943s  97656800s   logical   xfs
   6      585938976s  625000447s  39061472s   logical

If you need more detail, I'll be happy to help,
but it may take me a week or so.

Is rawhide using util-linux-ng that included the libblkid code?  It
seems we probably need to add a configure check to e2fsprogs not to
build libblkid if util-linux-ng has it.

Karel just sent a patch to do so (more or less), I think.

[PATCH] blkid: add --disable-libblkid to build with external libblkid

but AFAIK rawhide is still using e2fsprogs' blkid.  I'll look into it.

 Right, Fedora rawhide is using the latest stable util-linux-ng
 without libblkid.
