attached audit.log processed by audit2allow:

#============= insights_client_t ==============

allow insights_client_t insights_client_tmp_t:file relabelfrom;

Comment 4 Zdenek Pytela 2022-09-05 15:25:33 UTC

Pavol, Maria,

Can you retest with the following local selinux module?

rhel91# cat local_insights.cil
(allow insights_client_t insights_client_tmp_t (dir (relabelfrom relabelto)))
(allow insights_client_t insights_client_tmp_t (file (relabelfrom relabelto)))
(allow insights_client_t rhsmcertd_config_t (dir (write add_name)))
(allow insights_client_t rhsmcertd_config_t (file (create)))
(allow insights_client_t rpm_t (process (signal)))
(allow journalctl_t rhcd_t (fifo_file (read)))
(typetransition rhcd_t var_log_t file "hawkey.log" rpm_log_t)

rhel91# semodule -i local_insights.cil

Comment 7 Zdenek Pytela 2022-09-05 17:16:59 UTC

I keep getting different denials. Can you now try a different set?

chcon -t rpm_exec_t /usr/libexec/rhc/rhc-package-manager-worker
semodule -r local_insights
cat local_insights2.cil
(allow rhcd_t rpm_t (unix_stream_socket (connectto)))
(allow rhcd_t rpm_t (process (sigkill)))
(allow journalctl_t rhcd_t (fifo_file (read)))
(allow rhcd_t security_t (file (map)))
(allow rhcd_t self (netlink_audit_socket (nlmsg_write nlmsg_read create ioctl read getattr lock write setattr append bind connect getopt setopt shutdown)))

semodule -i local_insights2.cil
