resolv.conf is mislabeled. # /sbin/restorecon -v /etc/resolv.conf will fix. Could you reopen the bug if this happens again. Somewhere in your init scripts or a script launched out of dbus it is creating a resolv.conf with the wrong label. Are you using a tool like ppp? |
SELinux is preventing /bin/bash from 'write' accesses on the file /etc/resolv.conf. ***** Plugin restorecon (99.5 confidence) suggests ************************* If you want to fix the label. /etc/resolv.conf default label should be net_conf_t. Then you can run restorecon. Do # /sbin/restorecon -v /etc/resolv.conf ***** Plugin catchall (1.49 confidence) suggests *************************** If you believe that bash should be allowed write access on the resolv.conf file 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 dhclient-script /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:object_r:etc_runtime_t:s0 Target Objects /etc/resolv.conf [ file ] Source dhclient-script Source Path /bin/bash Port <Unknown> Host (removed) Source RPM Packages bash-4.2.10-4.fc15 Target RPM Packages Policy RPM selinux-policy-3.9.16-38.fc15 Selinux Enabled True Policy Type targeted Enforcing Mode Enforcing Host Name (removed) Platform Linux (removed) 2.6.40.4-5.fc15.i686 #1 SMP Tue Aug 30 14:54:41 UTC 2011 i686 i686 Alert Count 2 First Seen Thu 08 Sep 2011 10:21:16 PM EEST Last Seen Thu 08 Sep 2011 10:21:16 PM EEST Local ID 29ec74d0-d379-4474-a234-bbeb52024302 Raw Audit Messages type=AVC msg=audit(1315509676.219:92): avc: denied { write } for pid=3007 comm="dhclient-script" name="resolv.conf" dev=dm-1 ino=13956 scontext=unconfined_u:system_r:dhcpc_t:s0-s0:c0.c1023 tcontext=unconfined_u:object_r:etc_runtime_t:s0 tclass=file type=SYSCALL msg=audit(1315509676.219:92): arch=i386 syscall=open success=no exit=EACCES a0=9c6b888 a1=8201 a2=0 a3=0 items=0 ppid=2928 pid=3007 auid=528 uid=0 gid=0 euid=0 suid=0 fsuid=0 egid=0 sgid=0 fsgid=0 tty=(none) ses=1 comm=dhclient-script exe=/bin/bash subj=unconfined_u:system_r:dhcpc_t:s0-s0:c0.c1023 key=(null) Hash: dhclient-script,dhcpc_t,etc_runtime_t,file,write audit2allow #============= dhcpc_t ============== allow dhcpc_t etc_runtime_t:file write; audit2allow -R #============= dhcpc_t ============== allow dhcpc_t etc_runtime_t:file write;
