Description of problem: SELinux is preventing snap-update-ns from using the 'dac_override' capabilities. ***** Plugin dac_override (91.4 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 (9.59 confidence) suggests ************************** If you believe that snap-update-ns 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 'snap-update-ns' --raw | audit2allow -M my-snapupdatens # semodule -X 300 -i my-snapupdatens.pp Additional Information: Source Context system_u:system_r:snappy_mount_t:s0 Target Context system_u:system_r:snappy_mount_t:s0 Target Objects Unknown [ capability ] Source snap-update-ns Source Path snap-update-ns Port <Unknown> Host (removed) Source RPM Packages Target RPM Packages SELinux Policy RPM selinux-policy-targeted-36.10-1.fc36.noarch Local Policy RPM snapd-selinux-2.55.3-1.fc36.noarch Selinux Enabled True Policy Type targeted Enforcing Mode Enforcing Host Name (removed) Platform Linux (removed) 5.17.11-300.fc36.x86_64 #1 SMP PREEMPT Wed May 25 15:04:05 UTC 2022 x86_64 x86_64 Alert Count 1 First Seen 2022-06-07 12:07:52 MDT Last Seen 2022-06-07 12:07:52 MDT Local ID 21ba000e-15e6-4085-a958-35f61d006977 Raw Audit Messages type=AVC msg=audit(1654625272.597:3738): avc: denied { dac_override } for pid=189261 comm="snap-update-ns" capability=1 scontext=system_u:system_r:snappy_mount_t:s0 tcontext=system_u:system_r:snappy_mount_t:s0 tclass=capability permissive=1 Hash: snap-update-ns,snappy_mount_t,snappy_mount_t,capability,dac_override Version-Release number of selected component: selinux-policy-targeted-36.10-1.fc36.noarch Additional info: component: snapd reporter: libreport-2.17.1 hashmarkername: setroubleshoot kernel: 5.17.14-300.fc36.x86_64 type: libreport
