Package: util-linux
Version: 2.27-1
Severity: important
Control: affects -1 cryptmount
This breaks cryptmount when run as a user. cryptmount tries to use
/sbin/fsck to check the filesystem, /sbin/fsck fails to be able to run
the correct filesystem check, returns an error and cryptmount refuses to
mount that filesystem.
For example:
$ cryptmount gpg
Enter password for target "gpg":
[cryptmount-fsck]: error 2 (No such file or directory) while executing
fsck.ext2 for /dev/mapper/gpg
Correct behaviour:
$ /sbin/fsck /dev/null
fsck from util-linux 2.26.2
e2fsck 1.42.13 (17-May-2015)
fsck.ext2: Inappropriate ioctl for device while trying to open /dev/null
The superblock could not be read or does not describe a valid ext2/ext3/ext4
filesystem. If the device is valid and it really contains an ext2/ext3/ext4
filesystem (and not swap or ufs or something else), then the superblock
is corrupt, and you might try running e2fsck with an alternate superblock:
e2fsck -b 8193 <device>
or
e2fsck -b 32768 <device>
Incorrect behaviour:
$ /sbin/fsck /dev/null
fsck from util-linux 2.27
fsck: error 2 (No such file or directory) while executing fsck.ext2 for
/dev/null
This is 2.26.2:
$ strings $(which /sbin/fsck)|grep sbin
/sbin:/sA
:/sbin/fI
/sbin:/sbin/fs.d:/sbin/fs
and this is 2.27:
$ strings $(which /sbin/fsck)|grep sbin
/sbin
This suggests that /sbin/fsck is no longer adding /sbin to the path to
search for fsck.${fstype} programs.
It is possible to work around this change in behaviour by adding /sbin
to the PATH, thus:
$ PATH=$PATH:/sbin /sbin/fsck /dev/null
fsck from util-linux 2.27
