Hi Brian, are you running frr in a VM? Judging from the netdev-virbr0 device in the AVC message. @mruprich No. Hi Brian, did you have something I could answer here? You set the needinfo but I don't see a question. Regards, Michal Michal, no, nothing you need to answer. I was simply answering your question and mentioned your name (@mruprich). I have been getting an inclination lately that doing so adds the needinfo flag but I am not yet positive. I guess if this comment sets that flag for you again, we can conclude that it does.

Description of problem: Don't know why this happened. SELinux is preventing zebra from 'module_request' accesses on the system labeled kernel_t. ***** Plugin catchall_boolean (89.3 confidence) suggests ****************** If you want to allow all domains to have the kernel load modules Then you must tell SELinux about this by enabling the 'domain_kernel_load_modules' boolean. Do setsebool -P domain_kernel_load_modules 1 ***** Plugin catchall (11.6 confidence) suggests ************************** If you believe that zebra should be allowed module_request access on system labeled kernel_t 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 'zebra' --raw | audit2allow -M my-zebra # semodule -X 300 -i my-zebra.pp Additional Information: Source Context system_u:system_r:frr_t:s0 Target Context system_u:system_r:kernel_t:s0 Target Objects Unknown [ system ] Source zebra Source Path zebra Port <Unknown> Host (removed) Source RPM Packages Target RPM Packages SELinux Policy RPM selinux-policy-targeted-37.14-1.fc37.noarch Local Policy RPM frr-selinux-8.4-1.fc37.noarch Selinux Enabled True Policy Type targeted Enforcing Mode Enforcing Host Name (removed) Platform Linux (removed) 6.0.9-300.fc37.x86_64 #1 SMP PREEMPT_DYNAMIC Wed Nov 16 17:36:22 UTC 2022 x86_64 x86_64 Alert Count 2 First Seen 2022-11-22 08:59:49 EST Last Seen 2022-11-26 13:41:22 EST Local ID 8917d704-78e3-4eea-be33-4bce05a720f3 Raw Audit Messages type=AVC msg=audit(1669488082.469:231): avc: denied { module_request } for pid=1239 comm="zebra" kmod="netdev-virbr0" scontext=system_u:system_r:frr_t:s0 tcontext=system_u:system_r:kernel_t:s0 tclass=system permissive=0 Hash: zebra,frr_t,kernel_t,system,module_request Version-Release number of selected component: selinux-policy-targeted-37.14-1.fc37.noarch Additional info: component: frr reporter: libreport-2.17.4 hashmarkername: setroubleshoot kernel: 6.0.9-300.fc37.x86_64 type: libreport
