Description of problem: I added user 'user' in Fedora docker container. Then run 'su - user' inside container. This caused the AVC on Host SELinux is preventing su from 'link' accesses on the key Unknown. ***** Plugin catchall (100. confidence) suggests ************************** If you believe that su should be allowed link access on the Unknown key 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 su /var/log/audit/audit.log | audit2allow -M mypol # semodule -i mypol.pp Additional Information: Source Context system_u:system_r:svirt_lxc_net_t:s0:c357,c608 Target Context unconfined_u:unconfined_r:unconfined_t:s0-s0:c0.c1 023 Target Objects Unknown [ key ] Source su Source Path su Port <Unknown> Host (removed) Source RPM Packages Target RPM Packages Policy RPM selinux-policy-3.13.1-128.12.fc22.noarch Selinux Enabled True Policy Type targeted Enforcing Mode Enforcing Host Name (removed) Platform Linux (removed) 4.0.4-301.fc22.x86_64 #1 SMP Thu May 21 13:10:33 UTC 2015 x86_64 x86_64 Alert Count 1 First Seen 2015-09-04 13:14:33 CEST Last Seen 2015-09-04 13:14:33 CEST Local ID f511309d-68c6-4a89-a220-cf65201a0ffc Raw Audit Messages type=AVC msg=audit(1441365273.2:7812): avc: denied { link } for pid=10899 comm="su" scontext=system_u:system_r:svirt_lxc_net_t:s0:c357,c608 tcontext=unconfined_u:unconfined_r:unconfined_t:s0-s0:c0.c1023 tclass=key permissive=0 Hash: su,svirt_lxc_net_t,unconfined_t,key,link Version-Release number of selected component: selinux-policy-3.13.1-128.12.fc22.noarch Additional info: reporter: libreport-2.6.2 hashmarkername: setroubleshoot kernel: 4.0.4-301.fc22.x86_64 type: libreport
