This does seem to work but surely there's a tidier way of handling those
class requirements? What am I missing?
You want to use the "policy_module(procmail,0.1)" macro instead of the
module statement at the top. It adds all of the kernel object classes,
so you don't have to write them all out.
Thanks, that's much better:
policy_module(procmail, 0.2)
require {
type procmail_t;
type sbin_t;
type var_log_t;
};
# Needed for writing to /var/log/procmail.log
allow procmail_t var_log_t:dir search;
allow procmail_t var_log_t:file append;
# ==============================================
# Procmail needs to call sendmail for forwarding
# ==============================================
# This should be in selinux-policy-2.2.34-2 onwards
# Read alternatives link
allow procmail_t sbin_t:lnk_file read;
# Allow transition to sendmail
# (may need similar code for other MTAs that can replace sendmail)
optional_policy(`sendmail',`
sendmail_domtrans(procmail_t)
')
Cheers, Paul.
