Hi, Do you know at which moment this denial appears? As the capability is quite powerful, more information is needed. If you can reproduce it, please enable full auditing: 1) Open the /etc/audit/rules.d/audit.rules file in an editor. 2) Remove the following line if it exists: -a task,never 3) Add the following line to the end of the file: -w /etc/shadow -p w 4) Restart the audit daemon: # service auditd restart or reboot the system. 5) Re-run your scenario. 6) Collect AVC denials: # ausearch -i -m avc,user_avc,selinux_err,user_selinux_err -ts today |
Description of problem: SELinux is preventing nm-dispatcher from using the 'sys_admin' capabilities. ***** Plugin catchall (100. confidence) suggests ************************** If you believe that nm-dispatcher 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 'nm-dispatcher' --raw | audit2allow -M my-nmdispatcher # semodule -X 300 -i my-nmdispatcher.pp Additional Information: Source Context system_u:system_r:NetworkManager_dispatcher_t:s0 Target Context system_u:system_r:NetworkManager_dispatcher_t:s0 Target Objects Unknown [ capability ] Source nm-dispatcher Source Path nm-dispatcher Port <Unknown> Host (removed) Source RPM Packages Target RPM Packages SELinux Policy RPM selinux-policy-targeted-38.17-1.fc38.noarch Local Policy RPM selinux-policy-targeted-38.17-1.fc38.noarch Selinux Enabled True Policy Type targeted Enforcing Mode Enforcing Host Name (removed) Platform Linux (removed) 6.3.8-200.fc38.x86_64 #1 SMP PREEMPT_DYNAMIC Thu Jun 15 02:15:40 UTC 2023 x86_64 Alert Count 20 First Seen 2023-06-27 20:31:38 CEST Last Seen 2023-06-28 11:18:14 CEST Local ID 65f11ef2-e975-4769-bb8a-00f42e148795 Raw Audit Messages type=AVC msg=audit(1687943894.608:2698977): avc: denied { sys_admin } for pid=2583223 comm="nm-dispatcher" capability=21 scontext=system_u:system_r:NetworkManager_dispatcher_t:s0 tcontext=system_u:system_r:NetworkManager_dispatcher_t:s0 tclass=capability permissive=0 Hash: nm-dispatcher,NetworkManager_dispatcher_t,NetworkManager_dispatcher_t,capability,sys_admin Version-Release number of selected component: selinux-policy-targeted-38.17-1.fc38.noarch Additional info: reporter: libreport-2.17.10 reason: SELinux is preventing nm-dispatcher from using the 'sys_admin' capabilities. package: selinux-policy-targeted-38.17-1.fc38.noarch component: selinux-policy hashmarkername: setroubleshoot type: libreport kernel: 6.3.8-200.fc38.x86_64 event_log: 2023-06-28-11:19:44> Looking for similar problems in bugzilla component: selinux-policy
