The list command is not affected by the priority setting. Maybe it should be? Currently the priority is defaulted to 400 in semodule, but we could have it default to 0 and check in the -i/u/r cases for 0 and set to 400 and then filter the modules in -l if priority != 0. > > > 3) I can't remove the permissive domain created before the migration > because the default priority level is 400, but the script put everything > at priority 100 and I don't know how to change the priority for > semanage. semanage hasn't been updated yet to let you specify priorities. > > # semanage permissive -d httpd_t > libsemanage.semanage_direct_remove_key: Unable to remove module > directory /var/lib/selinux/targeted/tmp/modules/400/permissive_httpd_t. > (No such file or directory). > /usr/sbin/semanage: Could not remove permissive domain httpd_t (remove > failed) > > > Ports and file contexts addition and removal seems to work fine. > > -- > James Carter <jwcart2@xxxxxxxxxxxxx> > National Security Agency > -- This message was distributed to subscribers of the selinux mailing list.
