Description Karel Srot 2013-03-08 11:50:50 UTC
Description of problem:

On a newly installed system I have:

# ls -Zd /etc/multipath
drwxr-xr-x. root root system_u:object_r:root_t:s0      /etc/multipath

# rpm -qa | grep multipath
# for P in `rpm -qa`; do rpm -q --scripts $P | grep -q multipath && echo $P; done
# ls -lZR /etc/multipath
-rw-------. root root system_u:object_r:root_t:s0      bindings

but the correct context is lvm_metadata_t (see bug 880407).

in anaconda.log I can see:

11:21:28,431 INFO    : moving (1) to step preinstallconfig
11:21:28,432 DEBUG   : preinstallconfig is a direct step
11:21:28,456 DEBUG   : isys.py:mount()- going to mount /selinux on /mnt/sysimage/selinux as selinuxfs with options defaults
11:21:28,459 DEBUG   : isys.py:mount()- going to mount /proc/bus/usb on /mnt/sysimage/proc/bus/usb as usbfs with options defaults
11:21:28,467 INFO    : copy_to_sysimage: source '/etc/multipath/wwids' does not exist.
11:21:28,467 DEBUG   : copy_to_sysimage: '/etc/multipath/bindings' -> '/mnt/sysimage/etc/multipath/bindings'.
11:21:28,474 INFO    : copy_to_sysimage: source '/etc/multipath/wwids' does not exist.

11:21:28,477 INFO    : leaving (1) step preinstallconfig

seems that the context should be restored later on.

How reproducible:
always on the necessary system configuration

Steps to Reproduce:
1. just install the system
2. check /etc/multipath/binding
Actual results:
/etc/multipath directory has wrong selinux context

Expected results:
/etc/multipath (and its content) has correct selinux context

possible fix

I'm attaching an updates.img with a proposed fix. Would someone mind testing this out to verify the correct SELinux context is being set now?

updates.img w/possible fix

Bah; please ignore that first attachment and use this updates.img to test. (Sorry about that.)

Comment 12 Jan Stodola 2013-07-02 08:18:29 UTC
Testing with updates image from comment 11 looks good:

[root@rtt7 ~]# ls -lZ /etc/multipath
-rw-------. root root system_u:object_r:lvm_metadata_t:s0 bindings
-rw-------. root root system_u:object_r:lvm_metadata_t:s0 wwids
[root@rtt7 ~]# ls -lZd /etc/multipath
drwxr-xr-x. root root system_u:object_r:lvm_metadata_t:s0 /etc/multipath
[root@rtt7 ~]# restorecon -Rv /etc/multipath
[root@rtt7 ~]#
