Description of problem: Summary: SELinux is preventing iptables-save (iptables_t) "write" to /etc/sysconfig/iptables (etc_t). Detailed Description: SELinux is preventing iptables-save (iptables_t) "write" to /etc/sysconfig/iptables (etc_t). The SELinux type etc_t, is a generic type for all files in the directory and very few processes (SELinux Domains) are allowed to write to this SELinux type. This type of denial usual indicates a mislabeled file. By default a file created in a directory has the gets the context of the parent directory, but SELinux policy has rules about the creation of directories, that say if a process running in one SELinux Domain (D1) creates a file in a directory with a particular SELinux File Context (F1) the file gets a different File Context (F2). The policy usually allows the SELinux Domain (D1) the ability to write, unlink, and append on (F2). But if for some reason a file (/etc/sysconfig/iptables) was created with the wrong context, this domain will be denied. The usual solution to this problem is to reset the file context on the target file, restorecon -v '/etc/sysconfig/iptables'. If the file context does not change from etc_t, then this is probably a bug in policy. Please file a bug report (http://bugzilla.redhat.com/bugzilla/enter_bug.cgi) against the selinux-policy package. If it does change, you can try your application again to see if it works. The file context could have been mislabeled by editing the file or moving the file from a different directory, if the file keeps getting mislabeled, check the init scripts to see if they are doing something to mislabel the file. Allowing Access: You can attempt to fix file context by executing restorecon -v '/etc/sysconfig/iptables' Fix Command: restorecon '/etc/sysconfig/iptables' Additional Information: Source Context unconfined_u:unconfined_r:iptables_t:s0-s0:c0.c102 3 Target Context system_u:object_r:etc_t:s0 Target Objects /etc/sysconfig/iptables [ file ] Source iptables-save Source Path /sbin/iptables-save Port <Unknown> Host Yerushalayim.Yisrael Source RPM Packages iptables-1.4.1.1-2.fc10 Target RPM Packages Policy RPM selinux-policy-3.5.13-55.fc10 Selinux Enabled True Policy Type targeted MLS Enabled True Enforcing Mode Enforcing Plugin Name mislabeled_file Host Name Yerushalayim.Yisrael Platform Linux Yerushalayim.Yisrael 2.6.27.21-170.2.56.fc10.i686 #1 SMP Mon Mar 23 23:37:54 EDT 2009 i686 i686 Alert Count 2 First Seen Mon 27 Apr 2009 07:20:32 PM EDT Last Seen Mon 27 Apr 2009 07:46:14 PM EDT Local ID 70a1e04d-1b6f-4132-81c9-d60d1600d884 Line Numbers Raw Audit Messages node=Yerushalayim.Yisrael type=AVC msg=audit(1240875974.453:35): avc: denied { write } for pid=3289 comm="iptables-save" path="/etc/sysconfig/iptables" dev=dm-6 ino=26474 scontext=unconfined_u:unconfined_r:iptables_t:s0-s0:c0.c1023 tcontext=system_u:object_r:etc_t:s0 tclass=file node=Yerushalayim.Yisrael type=SYSCALL msg=audit(1240875974.453:35): arch=40000003 syscall=11 success=yes exit=0 a0=2310c90 a1=bf9594e8 a2=230c250 a3=cbbb00 items=0 ppid=3201 pid=3289 auid=500 uid=0 gid=0 euid=0 suid=0 fsuid=0 egid=0 sgid=0 fsgid=0 tty=pts0 ses=1 comm="iptables-save" exe="/sbin/iptables-save" subj=unconfined_u:unconfined_r:iptables_t:s0-s0:c0.c1023 key=(null) Version-Release number of selected component (if applicable): How reproducible: run command "iptables-save > /etc/sysconfig/iptables" from root Steps to Reproduce: 1. 2. 3.

Please update selinux-policy and selinux-policy-targeted packages. It should work.
