Bug Fix

Doc Text:

Cause: The /var/named/chroot/etc/localtime was created during the installation of the bind-chroot package, but its SELinux context was not restored. Consequence: As a consequence, the /var/named/chroot/etc/localtime had wrong SELinux context. Fix: The command to restore the SELinux context of /var/named/chroot/etc/localtime after creation has been added into the post transaction section of the SPEC file. Result: As a result, the /var/named/chroot/etc/localtime has now the correct SELinux context after installation of bind-chroot package.

Description	Flags
Restore SELinux context on /var/named/chroot/etc/localtime	none
Restore SELinux context on /var/named/chroot/etc/localtime	none

Description Karel Srot 2013-01-21 16:37:30 UTC

Description of problem:

Wrong selinux context is probably not causing any issues but I expect there is a reason for having the file to be locale_t.

# ls -Z /var/named/chroot/etc/localtime
-rw-r--r--. root root unconfined_u:object_r:etc_t:s0   /var/named/chroot/etc/localtime
# matchpathcon /var/named/chroot/etc/localtime
/var/named/chroot/etc/localtime	system_u:object_r:locale_t:s0


Version-Release number of selected component (if applicable):
bind-chroot-9.8.2-0.17.rc1.el6.x86_64
selinux-policy-3.7.19-194.el6.noarch


How reproducible:
always,
install bind-chroot and check the selinux context

missing restorecon ?

Comment 2 Miroslav Grepl 2013-01-22 12:47:36 UTC

[mgrepl@rhel6 ~]$ matchpathcon /var/named/chroot/etc/localtime
/var/named/chroot/etc/localtime	system_u:object_r:locale_t:s0

[mgrepl@rhel6 ~]$ rpm -qf /var/named/chroot/etc/localtime
bind-chroot-9.8.2-0.16.rc1.el6.x86_64


It should work.Or did you create it manually?

Comment 3 Karel Srot 2013-01-22 12:58:36 UTC

It is created by rpm postinstall script. Sorry for not mentioning it.

# rpm -q --scripts bind-chroot
postinstall scriptlet (using /bin/sh):
if [ "$1" -gt 0 ]; then
  [ -e /var/named/chroot/dev/random ] || \
    /bin/mknod /var/named/chroot/dev/random c 1 8
  [ -e /var/named/chroot/dev/zero ] || \
    /bin/mknod /var/named/chroot/dev/zero c 1 5
  [ -e /var/named/chroot/dev/null ] || \
    /bin/mknod /var/named/chroot/dev/null c 1 3
  rm -f /var/named/chroot/etc/localtime
  cp /etc/localtime /var/named/chroot/etc/localtime
  if ! grep -q '^ROOTDIR=' /etc/sysconfig/named; then
    echo 'ROOTDIR=/var/named/chroot' >> /etc/sysconfig/named
    /sbin/service named try-restart > /dev/null 2>&1 || :;
  fi
fi;

preuninstall scriptlet (using /bin/sh):
if [ "$1" -eq 0 ]; then
  rm -f /var/named/chroot/dev/{random,zero,null}
  rm -f /var/named/chroot/etc/localtime
  if grep -q '^ROOTDIR=' /etc/sysconfig/named; then
    # NOTE: Do NOT call `service named try-restart` because chroot
    # files will remain mounted.
    START=no
    [ -e /var/lock/subsys/named ] && START=yes
    /sbin/service named stop > /dev/null 2>&1 || :;
    sed -i -e '/^ROOTDIR=.*/d' /etc/sysconfig/named
    if [ "x$START" = xyes ]; then
      /sbin/service named start > /dev/null 2>&1 || :;
    fi

posttrans scriptlet (using /bin/sh):
