Subject: [2.5] double free in ext2?
Date: Fri, 7 Mar 2003 13:06:55 +0300 [thread overview]
Message-ID: <20030307130655.A17819@namesys.com> (raw)
Hello!
I am playing with smatch and while testing my improved version of
unfree.pl, I seems to have found a double free condition in ext2:
fs/ext2/super.c::ext2_fill_super() (I am looking at yesterday's 2.5 snapshot)
in line 784 we do kfree(sbi->s_group_desc); (then print "EXT2-fs: unable to read group descriptors\n")
and go to failed_mount_group_desc, which reads (from line 821):
failed_mount_group_desc:
kfree(sbi->s_group_desc);
2.4 is not affected.
Bye,
Oleg
