Description of problem: Procmail is not allowed to run /bin/ls, which is needed by a standard procmail rule. Either this rule should not be recommended or this usage should be allowed. Version-Release number of selected component (if applicable): selinux-policy-targeted-2.4.6-27.fc6 procmail-3.22-17.1 How reproducible: every time Steps to Reproduce: 1. add backup system to personal procmailrc according to procmailex manual page: :0 c backup :0 ic | cd backup && rm -f dummy `ls -t msg.* | sed -e 1,45d` 2. allow mail to arrive Actual results: avc: denied { signull } for comm="zsh" egid=500 euid=500 exe="/bin/zsh" exit=-13 fsgid=500 fsuid=500 gid=500 items=0 pid=5555 scontext=system_u:system_r:procmail_t:s0 sgid=500 subj=system_u:system_r:procmail_t:s0 suid=500 tclass=process tcontext=system_u:system_r:procmail_t:s0 tty=(none) uid=500 Expected results: Since this is a standard recommended use of procmail, the use should be permitted by default. Alternatively, the procmail manual should have a different example. E.g. you could do just the same thing Additional info: work around 1. put above audit message into a file (e.g. procmail-fixme.avc) 2. audit2allow -M procmail < procmail-fixme.avc 3. semodule -i procmail.pp
oops.. wrong message cut and paste (though the other one should probably be allowed too??) type=AVC msg=audit(1169892578.898:246): avc: denied { execute } for pid=3904 comm="zsh" name="ls" dev=dm-0 ino=349198 scontext=system_u:system_r:procmail_t:s0 tcontext=system_u:object_r:ls_exec_t:s0 tclass=file
Created attachment 146743 [details] actual audit log messages running with enforce off and basic policy just learning how to do it properly.. this seems to be what that should be fed into audit2allow.
Fixed in selinux-policy-2.4.6-33
Closed as all fixes are in the current release
