Description of problem: SELinux is preventing ipa-server-guar from 'search' accesses on the directory net. ***** Plugin catchall (100. confidence) suggests ************************** If you believe that ipa-server-guar should be allowed search access on the net directory 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 'ipa-server-guar' --raw | audit2allow -M my-ipaserverguar # semodule -X 300 -i my-ipaserverguar.pp Additional Information: Source Context system_u:system_r:certmonger_t:s0 Target Context system_u:object_r:sysctl_net_t:s0 Target Objects net [ dir ] Source ipa-server-guar Source Path ipa-server-guar Port <Unknown> Host (removed) Source RPM Packages Target RPM Packages SELinux Policy RPM selinux-policy-targeted-38.24-1.fc38.noarch Local Policy RPM selinux-policy-targeted-38.24-1.fc38.noarch Selinux Enabled True Policy Type targeted Enforcing Mode Enforcing Host Name (removed) Platform Linux (removed) 6.4.9-200.fc38.x86_64 #1 SMP PREEMPT_DYNAMIC Tue Aug 8 21:21:11 UTC 2023 x86_64 Alert Count 1476 First Seen 2023-07-13 20:09:00 BST Last Seen 2023-08-12 13:56:24 BST Local ID f3e3f090-022f-45d2-9c11-2205ae4d34dc Raw Audit Messages type=AVC msg=audit(1691844984.141:222): avc: denied { search } for pid=1513 comm="dogtag-ipa-ca-r" name="net" dev="proc" ino=2356 scontext=system_u:system_r:certmonger_t:s0 tcontext=system_u:object_r:sysctl_net_t:s0 tclass=dir permissive=0 Hash: ipa-server-guar,certmonger_t,sysctl_net_t,dir,search Version-Release number of selected component: selinux-policy-targeted-38.24-1.fc38.noarch Additional info: reporter: libreport-2.17.11 reason: SELinux is preventing ipa-server-guar from 'search' accesses on the directory net. package: selinux-policy-targeted-38.24-1.fc38.noarch component: selinux-policy hashmarkername: setroubleshoot type: libreport kernel: 6.4.9-200.fc38.x86_64 component: selinux-policy

James, Can you switch the system to permissive mode and gather all denials? setenforce 0 <reproduce> ausearch -i -m avc,user_avc,selinux_err,user_selinux_err -ts today setenforce 1
Apologies for taking many months to respond. I don't know exactly what triggers these denials, they seem to happen on boot so I set permissive mode then restarted. The machine is a FreeIPA server selinux-policy-targeted-39.3-1.fc39.noarch which has been re-labelled. ausearch output, with timestamps since the prior boot: type=AVC msg=audit(13/01/24

(Or is this a FreeIPA bug?)
Thank you. There are 3 buckets of denials: 1. certmonger - will be added to the policy 2. avahi dbus - requires to turn the httpd_dbus_avahi boolean on 3. a bug in rpcbind, already reported
