Does fail2ban want to execute shorewall? As far as I understand yes. It wants to be able to do a "shorewall drop [IP]" when it detects a violation. Note that this is not the default config as the fail2ban rpm config likes to do things directly in IPTables, but since I have shorewall installed I configured it to use shorewall to do the drops. Make sense. Fixed in selinux-policy-3.9.16-44.fc15 selinux-policy-3.9.16-48.fc15 has been submitted as an update for Fedora 15. https://admin.fedoraproject.org/updates/selinux-policy-3.9.16-48.fc15 Package selinux-policy-3.9.16-48.fc15: * should fix your issue, * was pushed to the Fedora 15 testing repository, * should be available at your local mirror within two days.

SELinux is preventing /bin/bash from 'getattr' accesses on the file /sbin/shorewall. ***** Plugin catchall (100. confidence) suggests *************************** If you believe that bash should be allowed getattr access on the shorewall 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 sh /var/log/audit/audit.log | audit2allow -M mypol # semodule -i mypol.pp Additional Information: Source Context system_u:system_r:fail2ban_t:s0 Target Context system_u:object_r:shorewall_exec_t:s0 Target Objects /sbin/shorewall [ file ] Source sh Source Path /bin/bash Port <Unknown> Host (removed) Source RPM Packages bash-4.2.10-4.fc15 Target RPM Packages shorewall-4.4.23.3-1.fc15 Policy RPM selinux-policy-3.9.16-39.fc15 Selinux Enabled True Policy Type targeted Enforcing Mode Enforcing Host Name (removed) Platform Linux (removed) 2.6.40.6-0.fc15.x86_64 #1 SMP Tue Oct 4 00:39:50 UTC 2011 x86_64 x86_64 Alert Count 18 First Seen Tue 11 Oct 2011 12:14:56 PM PDT Last Seen Thu 13 Oct 2011 05:33:03 PM PDT Local ID 5abde676-7810-4891-8266-8546320593a9 Raw Audit Messages type=AVC msg=audit(1318552383.104:1108): avc: denied { getattr } for pid=14734 comm="sh" path="/sbin/shorewall" dev=dm-0 ino=22256 scontext=system_u:system_r:fail2ban_t:s0 tcontext=system_u:object_r:shorewall_exec_t:s0 tclass=file type=SYSCALL msg=audit(1318552383.104:1108): arch=x86_64 syscall=stat success=no exit=EACCES a0=22ff860 a1=7fff6c8ce8f0 a2=7fff6c8ce8f0 a3=fffffffffffffff0 items=0 ppid=1534 pid=14734 auid=4294967295 uid=0 gid=0 euid=0 suid=0 fsuid=0 egid=0 sgid=0 fsgid=0 tty=(none) ses=4294967295 comm=sh exe=/bin/bash subj=system_u:system_r:fail2ban_t:s0 key=(null) Hash: sh,fail2ban_t,shorewall_exec_t,file,getattr audit2allow #============= fail2ban_t ============== allow fail2ban_t shorewall_exec_t:file getattr; audit2allow -R #============= fail2ban_t ============== allow fail2ban_t shorewall_exec_t:file getattr;
