Description of problem: SELinux is preventing /usr/bin/python2.7 from 'read' accesses on the directory /root/.local/lib/python2.7/site-packages. ***** Plugin catchall (100. confidence) suggests ************************** If you believe that python2.7 should be allowed read access on the site-packages directory 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 fail2ban-client /var/log/audit/audit.log | audit2allow -M mypol # semodule -i mypol.pp Additional Information: Source Context system_u:system_r:fail2ban_client_t:s0-s0:c0.c1023 Target Context unconfined_u:object_r:gconf_home_t:s0 Target Objects /root/.local/lib/python2.7/site-packages [ dir ] Source fail2ban-client Source Path /usr/bin/python2.7 Port <Unknown> Host (removed) Source RPM Packages python-2.7.8-7.fc21.x86_64 Target RPM Packages Policy RPM selinux-policy-3.13.1-105.3.fc21.noarch Selinux Enabled True Policy Type targeted Enforcing Mode Permissive Host Name (removed) Platform Linux (removed) 3.18.7-200.fc21.x86_64 #1 SMP Wed Feb 11 21:53:17 UTC 2015 x86_64 x86_64 Alert Count 1 First Seen 2015-03-15 23:17:52 GMT Last Seen 2015-03-15 23:17:52 GMT Local ID e0a34913-50d2-4821-a7de-99efcd6eb631 Raw Audit Messages type=AVC msg=audit(1426461472.988:24592): avc: denied { read } for pid=14584 comm="fail2ban-client" name="site-packages" dev="dm-0" ino=172178 scontext=system_u:system_r:fail2ban_client_t:s0-s0:c0.c1023 tcontext=unconfined_u:object_r:gconf_home_t:s0 tclass=dir permissive=1 type=SYSCALL msg=audit(1426461472.988:24592): arch=x86_64 syscall=openat success=yes exit=EINTR a0=ffffffffffffff9c a1=664ac0 a2=90800 a3=0 items=0 ppid=14583 pid=14584 auid=0 uid=0 gid=0 euid=0 suid=0 fsuid=0 egid=0 sgid=0 fsgid=0 tty=(none) ses=60 comm=fail2ban-client exe=/usr/bin/python2.7 subj=system_u:system_r:fail2ban_client_t:s0-s0:c0.c1023 key=(null) Hash: fail2ban-client,fail2ban_client_t,gconf_home_t,dir,read Version-Release number of selected component: selinux-policy-3.13.1-105.3.fc21.noarch Additional info: reporter: libreport-2.3.0 hashmarkername: setroubleshoot kernel: 3.18.7-200.fc21.x86_64 type: libreport
fail2ban python scripts should use #! /usr/bin/python -Es You don't want python accidentally/maliciously grabbing content from this directory.
Reported upstream. If this really is the case, seems like we should have a packaging guideline on this for all python daemons/services.
I agree with denial, I don't agree with attempt. :) Thanks for reporting upstream!
Orion, I agree. I think all shipping Python versions should really use these settings. Since it prevents bugs and potential attacks. Most users would never think that a file in their $HOME/.local/lib/python2.7/site-packages directory could break every python application on the system without this flag set.
