Description of problem: SELinux policy does not allow dnssec-triggerd to write to /etc, thus dnssec-triggerd is not able to write /etc/resolv.conf and my system ends up without /etc/resolv.conf completely. Version-Release number of selected component (if applicable): selinux-policy-3.13.1-105.3.fc21.noarch dnssec-trigger-0.12-17.fc22.x86_64 How reproducible: always Steps to Reproduce: 1. 2. 3. Actual results: Feb 24 09:02:46 thozza-pc dnssec-triggerd[1587]: [1587] notice: probe done: DNSSEC to auth direct Feb 24 09:02:46 thozza-pc dnssec-triggerd[1587]: ok Feb 24 09:02:46 thozza-pc dnssec-triggerd[1587]: ok Feb 24 09:02:46 thozza-pc dnssec-triggerd[1587]: chattr: No such file or directory while trying to stat /etc/resolv.conf Feb 24 09:02:46 thozza-pc dnssec-triggerd[1587]: [1587] error: chmod(/etc/resolv.conf) failed: No such file or directory Feb 24 09:02:46 thozza-pc dnssec-triggerd[1587]: [1587] error: cannot open /etc/resolv.conf: Permission denied Feb 24 09:02:48 thozza-pc python[13665]: SELinux is preventing /usr/sbin/dnssec-triggerd from write access on the directory /etc. ***** Plugin catchall_labels (83.8 confidence) suggests ******************* If you want to allow dnssec-triggerd to have write access on the etc directory Then you need to change the label on /etc Do # semanage fcontext -a -t FILE_TYPE '/etc' where FILE_TYPE is one of the following: dnssec_trigger_var_run_t, net_conf_t, var_run_t. Then execute: restorecon -v '/etc' ***** Plugin catchall (17.1 confidence) suggests ************************** If you believe that dnssec-triggerd should be allowed write access on the etc directory 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 dnssec-triggerd /var/log/audit/audit.log | audit2allow -M mypol # semodule -i mypol.pp Expected results: SELinux NOT preventing dnssec-triggerd to write to /etc/resolv.conf!
