Summary: SELinux is preventing /usr/sbin/rndc access to a leaked /root file descriptor. Detailed Description: [rndc has a permissive type (ndc_t). This access was not denied.] SELinux denied access requested by the rndc command. It looks like this is either a leaked descriptor or rndc output was redirected to a file it is not allowed to access. Leaks usually can be ignored since SELinux is just closing the leak and reporting the error. The application does not use the descriptor, so it will run properly. If this is a redirection, you will not get output in the /root. You should generate a bugzilla on selinux-policy, and it will get routed to the appropriate package. You can safely ignore this avc. Allowing Access: You can generate a local policy module to allow this access - see FAQ (http://docs.fedoraproject.org/selinux-faq-fc5/#id2961385) Additional Information: Source Context system_u:system_r:ndc_t:s0 Target Context system_u:object_r:admin_home_t:s0 Target Objects /root [ dir ] Source rndc Source Path /usr/sbin/rndc Port <Unknown> Host (removed) Source RPM Packages bind-9.7.1-2.P2.fc13 Target RPM Packages filesystem-2.4.31-1.fc13 Policy RPM selinux-policy-3.7.19-44.fc13 Selinux Enabled True Policy Type targeted Enforcing Mode Enforcing Plugin Name leaks Host Name (removed) Platform Linux (removed) 2.6.33.6-147.2.4.fc13.x86_64 #1 SMP Fri Jul 23 17:14:44 UTC 2010 x86_64 x86_64 Alert Count 1 First Seen Thu 12 Aug 2010 03:30:17 AM PDT Last Seen Thu 12 Aug 2010 03:30:17 AM PDT Local ID 9d3ed27c-a05f-4d01-a399-f29125337c7d Line Numbers Raw Audit Messages node=(removed) type=AVC msg=audit(1281609017.624:38391): avc: denied { read } for pid=14496 comm="rndc" path="/root" dev=dm-3 ino=81921 scontext=system_u:system_r:ndc_t:s0 tcontext=system_u:object_r:admin_home_t:s0 tclass=dir node=(removed) type=SYSCALL msg=audit(1281609017.624:38391): arch=c000003e syscall=59 success=yes exit=0 a0=e503b0 a1=e50010 a2=e50680 a3=18 items=0 ppid=14493 pid=14496 auid=0 uid=0 gid=0 euid=0 suid=0 fsuid=0 egid=0 sgid=0 fsgid=0 tty=(none) ses=29 comm="rndc" exe="/usr/sbin/rndc" subj=system_u:system_r:ndc_t:s0 key=(null) Hash String generated from leaks,rndc,ndc_t,admin_home_t,dir,read audit2allow suggests: #============= ndc_t ============== allow ndc_t admin_home_t:dir read;
I believe this was the result of locally generated shell script run from cron.daily that ran a make(1) which among other things executed these commands: install (list of files into /var/named/...) rndc freeze service named stop service named start bind version installed: Name : bind Arch : x86_64 Epoch : 32 Version : 9.7.1 Release : 2.P2.fc13
You can dont' audit it for now using # grep ndc_t /var/log/audit/audit.log | audit2allow -D -M mypol # semodule -i mypol.pp
