Description of problem: When launching Nautilus after a system update, two SELinux Alerts appears about systemd (about read and getattr access). The alerts read as follows: Alert #1: SELinux is preventing /usr/lib/systemd/systemd-hostnamed from read access on the file /etc/hostname. ***** Plugin restorecon (99.5 confidence) suggests ************************* If you want to fix the label. /etc/hostname default label should be etc_t. Then you can run restorecon. Do # /sbin/restorecon -v /etc/hostname ***** Plugin catchall (1.49 confidence) suggests *************************** If you believe that systemd-hostnamed should be allowed read access on the hostname file by default. Then you should report this as a bug. You can generate a local policy module to allow this access. Do allow this access for now by executing: # grep systemd-hostnam /var/log/audit/audit.log | audit2allow -M mypol # semodule -i mypol.pp Additional Information: Source Context system_u:system_r:systemd_hostnamed_t:s0 Target Context system_u:object_r:etc_runtime_t:s0 Target Objects /etc/hostname [ file ] Source systemd-hostnam Source Path /usr/lib/systemd/systemd-hostnamed Port <Unknown> Host localhost.private Source RPM Packages systemd-197-1.fc18.2.x86_64 Target RPM Packages systemd-197-1.fc18.2.x86_64 Policy RPM selinux-policy-3.11.1-82.fc18.noarch Selinux Enabled True Policy Type targeted Enforcing Mode Enforcing Host Name localhost.private Platform Linux localhost.private 3.8.1-201.fc18.x86_64 #1 SMP Thu Feb 28 19:23:08 UTC 2013 x86_64 x86_64 Alert Count 1 First Seen 2013-03-09 22:39:20 EST Last Seen 2013-03-09 22:39:20 EST Local ID bebba614-de58-4244-b732-b6d939ed1edf Raw Audit Messages type=AVC msg=audit(1362886760.43:318): avc: denied { read } for pid=1775 comm="systemd-hostnam" name="hostname" dev="sda3" ino=1415419 scontext=system_u:system_r:systemd_hostnamed_t:s0 tcontext=system_u:object_r:etc_runtime_t:s0 tclass=file type=AVC msg=audit(1362886760.43:318): avc: denied { open } for pid=1775 comm="systemd-hostnam" path="/etc/hostname" dev="sda3" ino=1415419 scontext=system_u:system_r:systemd_hostnamed_t:s0 tcontext=system_u:object_r:etc_runtime_t:s0 tclass=file type=SYSCALL msg=audit(1362886760.43:318): arch=x86_64 syscall=open success=yes exit=EINTR a0=7f8cb3022d68 a1=80000 a2=1b6 a3=238 items=0 ppid=1 pid=1775 auid=4294967295 uid=0 gid=0 euid=0 suid=0 fsuid=0 egid=0 sgid=0 fsgid=0 ses=4294967295 tty=(none) comm=systemd-hostnam exe=/usr/lib/systemd/systemd-hostnamed subj=system_u:system_r:systemd_hostnamed_t:s0 key=(null) Hash: systemd-hostnam,systemd_hostnamed_t,etc_runtime_t,file,read audit2allow #============= systemd_hostnamed_t ============== allow systemd_hostnamed_t etc_runtime_t:file { read open }; audit2allow -R #============= systemd_hostnamed_t ============== allow systemd_hostnamed_t etc_runtime_t:file { read open }; Alert #2: SELinux is preventing /usr/lib/systemd/systemd-hostnamed from getattr access on the file /etc/hostname. ***** Plugin restorecon (99.5 confidence) suggests ************************* If you want to fix the label. /etc/hostname default label should be etc_t.
