I'm trying to understand and looking for clarity with future events when presented with an option to either generate an allow rule using audit2allow or to execute setsebool to resolve an AVC denial, which would be considered the correct option given the
following event below? I can't seem to find the answer via Google or maybe I'm phrasing the question incorrectly.
Thanks in advance.
Cheers,

SELinux is preventing plugin-containe from using the dac_override capability. ***** Plugin mozplugger (87.7 confidence) suggests ************************ If you want to use the plugin package Then you must turn off SELinux controls on the Firefox plugins. Do # setsebool -P unconfined_mozilla_plugin_transition 0 ***** Plugin dac_override (12.1 confidence) suggests ********************** If you want to help identify if domain needs this access or you have a file with the wrong permissions on your system Then turn on full auditing to get path information about the offending file and generate the error again. Do Turn on full auditing # auditctl -w /etc/shadow -p w Try to recreate AVC. Then execute # ausearch -m avc -ts recent If you see PATH record check ownership/permissions on file, and fix it, otherwise report as a bugzilla. ***** Plugin catchall (1.66 confidence) suggests ************************** If you believe that plugin-containe should have the dac_override capability 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: # ausearch -c 'plugin-containe' --raw | audit2allow -M my-plugincontaine # semodule -X 300 -i my-plugincontaine.pp Additional Information: Source Context unconfined_u:unconfined_r:mozilla_plugin_t:s0-s0:c0.c1023 Target Context unconfined_u:unconfined_r:mozilla_plugin_t:s0-s0:c0.c1023 Target Objects Unknown [ capability ] Source plugin-containe Source Path plugin-containe Port <Unknown> Host <removed> Source RPM Packages Target RPM Packages Policy RPM selinux-policy-3.13.1-191.19.fc24.noarch Selinux Enabled True Policy Type targeted Enforcing Mode Enforcing Host Name <removed> Platform Linux <removed> 4.8.4-200.fc24.x86_64 #1 SMP Tue Oct 25 13:06:04 UTC 2016 x86_64 x86_64 Alert Count 3 First Seen 2016-11-06 10:23:58 MST Last Seen 2016-11-06 10:43:52 MST Local ID 4ae65592-42a8-4141-8977-fdef20ee84aa Raw Audit Messages type=AVC msg=audit(1478454232.260:418): avc: denied { dac_override } for pid=5985 comm="plugin-containe" capability=1 scontext=unconfined_u:unconfined_r:mozilla_plugin_t:s0-s0:c0.c1023 tcontext=unconfined_u:unconfined_r:mozilla_plugin_t:s0-s0:c0.c1023 tclass=capability permissive=0 Hash: plugin-containe,mozilla_plugin_t,mozilla_plugin_t,capability,dac_override |
