Description of problem: During an installation of FreeIPA in a container, most probably during the `pkispawn` time, there is a `mv` which tries to relabel two objects so that the MCS part of their context gets removed. Version-Release number of selected component (if applicable): Fedora 26 host, on Fedora 25 host this seems to work fine How reproducible: 100% Steps to Reproduce: 1. docker pull freeipa/freeipa-server:fedora-26 2. domain=IPA.TEST; docker run -t --name freeipa-popelnice -h $HOSTNAME \ --tmpfs /run --tmpfs /tmp \ -v /dev/urandom:/dev/random:ro -v /opt/ipa-data/master:/data \ -v /sys/fs/cgroup:/sys/fs/cgroup:ro --cap-add=SYS_TIME \ freeipa/freeipa-server:fedora-26 \ --hostname $HOSTNAME --domain $domain --realm ${domain^^} \ -p milan_je_buh123 -a milan_je_buh123 --setup-dns --auto-forwarders --no-reverse -U 3. ausearch -m avc Actual results: ---- time->Mon Nov 27 02:44:49 2017 type=AVC msg=audit(1511768689.168:475): avc: denied { relabelfrom } for pid=16032 comm="mv" name="logging.properties" dev="dm-0" ino=26096381 scontext=system_u:system_r:container_t:s0:c178,c726 tcontext=system_u:object_r:container_file_t:s0 tclass=lnk_file permissive=0 ---- time->Mon Nov 27 02:44:49 2017 type=AVC msg=audit(1511768689.176:476): avc: denied { relabelfrom } for pid=16032 comm="mv" name="CS.cfg.bak" dev="dm-0" ino=26096406 scontext=system_u:system_r:container_t:s0:c178,c726 tcontext=system_u:object_r:container_file_t:s0 tclass=lnk_file permissive=0 Fail: AVC messages found. Expected results: No AVCs Additional info: Running the container requires more workarounds, I will add an appropriate beaker job to this BZ.
This is strange, It looks like the system thinks SElinux is enabled within the container? If you run this same container but just launch and run a sh, does id -Z report that SELinux is disabled?
`docker exec $CONTAINER_NAME id -Z` seems to correctly give: """ id: --context (-Z) works only on an SELinux-enabled kernel """
Ok does some code do a mv -Z from inside of the contaiener on top of /opt/ipa-darta-master? Is this content private to this container or do other containers need to use this data? -v /opt/ipa-data-master:/data:Z Would fix this issue if it is private to this container. And you could eliminate the chcon command from above.
Ok I got it. Fixed in container-selinux-2.36
Thanks. For the record - the data in /opt/ipa-data-master are supposed to be persistent container storage and can be used in different containers so the :Z way is unfortunately not possible.
We were allowing the relabel on files and directories, but not on link_file which is what you are seeing. I have updated container-selinux do allow it on all file types now.
Thanks, tested the new package from koji and it seems to have fixed the problem for me.
Ok I will push it into updates as tomorrow, since we have a container-selinux package update about to finish the updates process. Once I push, could you update karma.
