I modified my policy as follows:
module procmailauth 1.0;
require {
type procmail_t;
type var_log_t;
type spamassassin_exec_t;
type spamd_var_lib_t;
class dir search;
class dir execute;
class dir getattr;
class dir read;
class dir ioctl;
class file read;
class file ioctl;
class file execute;
class file execute_no_trans;
class file write;
class file getattr;
class file append;
}
#============= dovecot_auth_t ==============
allow procmail_t spamassassin_exec_t:file { read ioctl write getattr execute execute_no_tran
s append };
allow procmail_t spamassassin_exec_t:dir { getattr execute };
allow procmail_t spamd_var_lib_t:file { getattr read ioctl};
allow procmail_t spamd_var_lib_t:dir { getattr read search ioctl };
This appears to be holding - procmail logs don't complain, procmail results are
achieved, and no sealerts in messages.
I'll let you know if this breaks.
Thanks

Description of problem: SELinux is preventing sh (procmail_t) "getattr" to /usr/bin/spamassassin (spamassassin_exec_t). SELinux is preventing sh (procmail_t) "execute" to ./spamassassin (spamassassin_exec_t). Version-Release number of selected component (if applicable): selinux-policy-strict-2.4.6-203.el5 selinux-policy-mls-2.4.6-203.el5 selinux-policy-devel-2.4.6-203.el5 selinux-policy-targeted-2.4.6-203.el5 selinux-policy-2.4.6-203.el5 How reproducible: This started on the recent selinux upgrade which is now preventing procmail scripts from checking incoming e-mail against spamassassin. Steps to Reproduce: 1. 2. 3. Actual results: Expected results: Additional info: I wrote the following policy to try to fix this problem: module procmailauth 1.0; require { type procmail_t; type var_log_t; type spamassassin_exec_t; type spamd_var_lib_t; class dir search; class dir execute; class file read; class file ioctl; class file execute; class file write; class file getattr; class file append; } #============= dovecot_auth_t ============== allow procmail_t spamassassin_exec_t:file { read ioctl write getattr append }; allow procmail_t spamassassin_exec_t:dir execute; allow procmail_t spamd_var_lib_t:dir search; The above didn't fix the problem. In fact additional sealerts like "ioctl" started occurring. So how may this problem be fixed?
