Description of problem: SELinux is preventing sshd-session from 'getattr' accesses on the Datei /proc/sys/net/ipv6/conf/all/disable_ipv6. ***** Plugin catchall (100. confidence) suggests ************************** Wenn Sie denken, dass es sshd-session standardmäßig erlaubt sein sollte, getattr Zugriff auf disable_ipv6 file zu erhalten. Then sie sollten dies als Fehler melden. Um diesen Zugriff zu erlauben, können Sie ein lokales Richtlinien-Modul erstellen. Do zugriff jetzt erlauben, indem Sie die nachfolgenden Befehle ausführen: # ausearch -c 'sshd-session' --raw | audit2allow -M my-sshdsession # semodule -X 300 -i my-sshdsession.pp Additional Information: Source Context system_u:system_r:sshd_session_t:s0-s0:c0.c1023 Target Context system_u:object_r:sysctl_net_t:s0 Target Objects /proc/sys/net/ipv6/conf/all/disable_ipv6 [ file ] Source sshd-session Source Path sshd-session Port <Unbekannt> Host (removed) Source RPM Packages Target RPM Packages SELinux Policy RPM selinux-policy-targeted-42.22-1.fc42.noarch Local Policy RPM selinux-policy-targeted-42.22-1.fc42.noarch Selinux Enabled True Policy Type targeted Enforcing Mode Enforcing Host Name (removed) Platform Linux (removed) 6.18.7-100.fc42.x86_64 #1 SMP PREEMPT_DYNAMIC Fri Jan 23 15:37:26 UTC 2026 x86_64 Alert Count 2 First Seen 2026-02-01 12:38:22 CET Last Seen 2026-02-01 12:38:26 CET Local ID 4259452f-9a97-4a27-8257-88575492b86f Raw Audit Messages type=AVC msg=audit(1769945906.568:934): avc: denied { getattr } for pid=41964 comm="sshd-session" path="/proc/sys/net/ipv6/conf/all/disable_ipv6" dev="proc" ino=12547 scontext=system_u:system_r:sshd_session_t:s0-s0:c0.c1023 tcontext=system_u:object_r:sysctl_net_t:s0 tclass=file permissive=1 Hash: sshd-session,sshd_session_t,sysctl_net_t,file,getattr Version-Release number of selected component: selinux-policy-targeted-42.22-1.fc42.noarch Additional info: reporter: libreport-2.17.15 kernel: 6.18.7-100.fc42.x86_64 package: selinux-policy-targeted-42.22-1.fc42.noarch reason: SELinux is preventing sshd-session from 'getattr' accesses on the Datei /proc/sys/net/ipv6/conf/all/disable_ipv6. type: libreport hashmarkername: setroubleshoot component: selinux-policy component: selinux-policy
