Each time an extent handle is opened and closed, if the inode has an
|
||||
extent tree which does not fit in the inode's i_block structure, a
|
||||
filesystem block buffer was not getting released. Since e2fsck opens
|
||||
an extent handle for every inode using extents, this can translate to
|
||||
a very large amount of memory getting lost.
|
||||
|
||||
Thanks to Henrik 'Mauritz' Johnson for discovering and pointing out
|
||||
this leak, which he ran into while running the "rdump" command in
|
||||
debugfs.

libext2fs: write only core inode in update_path()
|
||||
|
||||
The ext2_extent_handle only has a struct ext2_inode allocated on
|
||||
it, and the same amount copied into it in that same function,
|
||||
but in update_path() we're possibly writing out more than that -
|
||||
for example 256 bytes, from that address. This causes uninitialized
|
||||
memory to get written to disk, overwriting the parts of the
|
||||
inode past the osd2 member (the end of the smaller structure).

This was reported in Fedora, since the livecd creator does
|
||||
a lot of resizing.
|
||||
|
||||
If we've moved the journal blocks during resize (more likely now,
|
||||
due to the journal being in the middle) the backup blocks in the
|
||||
superblock don't get updated, and a subsequent e2fsck will find
|
||||
issues:

|

This can be shown in a simple test:
|
||||
|
||||
# dd if=/dev/zero of=img bs=1 count=0 seek=3000M
|
||||
# mke2fs -t ext4 -F img
|

(thanks to the Fedora reporter Mads Kiilerich for the testcase!
|
||||
https://bugzilla.redhat.com/show_bug.cgi?id=506105#c2)
|
||||
|
||||
So, update the backup journal in the superblock before resize2fs exits.
