ifup and ifdown are hanging SELinux is preventing /bin/systemctl from using the 'signal' accesses on a process. ***** Plugin catchall (100. confidence) suggests *************************** If you believe that systemctl should be allowed signal access on processes labeled systemd_passwd_agent_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: # grep systemctl /var/log/audit/audit.log | audit2allow -M mypol # semodule -i mypol.pp Additional Information: Source Context unconfined_u:system_r:dhcpc_t:s0-s0:c0.c1023 Target Context unconfined_u:system_r:systemd_passwd_agent_t:s0-s0 :c0.c1023 Target Objects Unknown [ process ] Source systemctl Source Path /bin/systemctl Port <Unknown> Host (removed) Source RPM Packages systemd-units-26-8.fc15 Target RPM Packages Policy RPM selinux-policy-3.9.16-34.fc15 Selinux Enabled True Policy Type targeted Enforcing Mode Enforcing Host Name (removed) Platform Linux (removed) 2.6.38.8-35.fc15.x86_64 #1 SMP Wed Jul 6 13:58:54 UTC 2011 x86_64 x86_64 Alert Count 3 First Seen Mon 01 Aug 2011 09:26:49 AM CEST Last Seen Mon 01 Aug 2011 09:31:10 AM CEST Local ID 6827c966-fd07-4c5b-99d4-6d424187f4e5 Raw Audit Messages type=AVC msg=audit(1312183870.174:1071): avc: denied { signal } for pid=26887 comm="systemctl" scontext=unconfined_u:system_r:dhcpc_t:s0-s0:c0.c1023 tcontext=unconfined_u:system_r:systemd_passwd_agent_t:s0-s0:c0.c1023 tclass=process type=SYSCALL msg=audit(1312183870.174:1071): arch=x86_64 syscall=kill success=no exit=EACCES a0=6908 a1=12 a2=d a3=0 items=0 ppid=26828 pid=26887 auid=1000 uid=0 gid=0 euid=0 suid=0 fsuid=0 egid=0 sgid=0 fsgid=0 tty=pts0 ses=1 comm=systemctl exe=/bin/systemctl subj=unconfined_u:system_r:dhcpc_t:s0-s0:c0.c1023 key=(null) Hash: systemctl,dhcpc_t,systemd_passwd_agent_t,process,signal audit2allow #============= dhcpc_t ============== allow dhcpc_t systemd_passwd_agent_t:process signal; audit2allow -R #============= dhcpc_t ============== allow dhcpc_t systemd_passwd_agent_t:process signal;
