Description of problem: I started system and seen alert in SELinux. I don't know what caused this issue. I had this alert twice before and after first time I have run commands: # ausearch -c 'snort' --raw | audit2allow -M my-snort # semodule -X 300 -i my-snort.pp But situation occurs again and again. SELinux is preventing snort from 'create' accesses on the netlink_netfilter_socket Nieznane. ***** Plugin catchall (100. confidence) suggests ************************** Aby snort powinno mieć domyślnie create dostęp do Nieznane netlink_netfilter_socket. Then proszę to zgłosić jako błąd. Można utworzyć lokalny moduł polityki, aby umożliwić ten dostęp. Do można tymczasowo zezwolić na ten dostęp wykonując polecenia: # ausearch -c 'snort' --raw | audit2allow -M my-snort # semodule -X 300 -i my-snort.pp Additional Information: Source Context system_u:system_r:snort_t:s0 Target Context system_u:system_r:snort_t:s0 Target Objects Nieznane [ netlink_netfilter_socket ] Source snort Source Path snort Port <Nieznane> Host (removed) Source RPM Packages Target RPM Packages Policy RPM <Nieznane> Selinux Enabled True Policy Type targeted Enforcing Mode Enforcing Host Name (removed) Platform Linux (removed) 5.1.8-300.fc30.x86_64 #1 SMP Sun Jun 9 17:09:32 UTC 2019 x86_64 x86_64 Alert Count 2 First Seen 2019-06-23 13:24:38 CEST Last Seen 2019-06-23 18:29:21 CEST Local ID b06f5fb2-909b-4af1-a368-9fd776c53d85 Raw Audit Messages type=AVC msg=audit(1561307361.872:91): avc: denied { create } for pid=977 comm="snort" scontext=system_u:system_r:snort_t:s0 tcontext=system_u:system_r:snort_t:s0 tclass=netlink_netfilter_socket permissive=0 Hash: snort,snort_t,snort_t,netlink_netfilter_socket,create Additional info: component: selinux-policy reporter: libreport-2.10.0 hashmarkername: setroubleshoot kernel: 5.1.8-300.fc30.x86_64 type: libreport Potential duplicate: bug 1274097
