You should be looking at logrotate_t not logwatch_t
# sesearch -A -s logrotate_t -p write -c file | grep logfile
allow logrotate_t logfile : file { ioctl read write create getattr setattr
lock append unlink link rename execute execute_no_trans open } ;
First off I would look at if this is actually necessary or just a leak. Why
would logrotate want to read/write dnsview.html? You might be best off adding
a dontaudit rule, although figuring out if this is a leak and fixing the leak
would be best.
Logwatch is allowed to manipulate log files so it is probably best to have
these be log files.
httpd_log_t maybe? If this is actually necessary.
Logtotate and logwatch are able to search any directory yes. But remember
search is different then list. I need to search through all directories in a
path, but if I want to see the contents of a directory I need the list priv.
