Description of problem: snapper delete fails to delete snapshots because of SELinux permission issues Version-Release number of selected component (if applicable): snapper-0.2.8-1.fc23.x86_64 How reproducible: All the time Steps to Reproduce: 1. configure snapper dnf plugin to make snapshot every dnf run 2. at later date run `snapper delete 1-50` Actual results: * "Deleting snapshot failed" printed to shell * "2016-06-01 13:28:53 ERR libsnapper(2559) Btrfs.cc(deleteSnapshot):363 - delete snapshot failed, ioctl(BTRFS_IOC_SNAP_DESTROY) failed, errno:1 (Operation not permitted" shows up in /var/log/snapper.log Expected results: snapshot(s) should be deleted Additional info: from /var/log/messages: Jun 1 13:16:47 catbug setroubleshoot: SELinux is preventing snapperd from using the sys_admin capability. For complete SELinux messages. run sealert -l d0d54b64-f937-499a-aa06-a1ffcfc4a79e running that command gave me: SELinux is preventing snapperd from using the sys_admin capability. ***** Plugin catchall (100. confidence) suggests ************************** If you believe that snapperd should have the sys_admin 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 'snapperd' --raw | audit2allow -M my-snapperd # semodule -X 300 -i my-snapperd.pp Additional Information: Source Context system_u:system_r:snapperd_t:s0-s0:c0.c1023 Target Context system_u:system_r:snapperd_t:s0-s0:c0.c1023 Target Objects Unknown [ capability ] Source snapperd Source Path snapperd Port <Unknown> Host catbug Source RPM Packages Target RPM Packages Policy RPM selinux-policy-3.13.1-158.15.fc23.noarch Selinux Enabled True Policy Type targeted Enforcing Mode Enforcing Host Name catbug Platform Linux catbug 4.4.9-300.fc23.x86_64 #1 SMP Wed May 4 23:56:27 UTC 2016 x86_64 x86_64 Alert Count 8 First Seen 2016-06-01 13:16:44 EDT Last Seen 2016-06-01 13:29:56 EDT Local ID d0d54b64-f937-499a-aa06-a1ffcfc4a79e Raw Audit Messages type=AVC msg=audit(1464802196.171:2857): avc: denied { sys_admin } for pid=858 comm="snapperd" capability=21 scontext=system_u:system_r:snapperd_t:s0-s0:c0.c1023 tcontext=system_u:system_r:snapperd_t:s0-s0:c0.c1023 tclass=capability permissive=0 Hash: snapperd,snapperd_t,snapperd_t,capability,sys_admin
