Description Milos Malik 2020-06-10 17:33:42 UTC
Description of problem:
 * both services belong to the subscription-manager component, which is shipped in RHEL, but they are not confined by SELinux policy

# matchpathcon /usr/libexec/rhsm-service
/usr/libexec/rhsm-service	system_u:object_r:bin_t:s0
# matchpathcon /usr/libexec/rhsm-facts-service 
/usr/libexec/rhsm-facts-service	system_u:object_r:bin_t:s0
#

Version-Release number of selected component (if applicable):
selinux-policy-3.14.3-41.el8.noarch
selinux-policy-targeted-3.14.3-41.el8.noarch
subscription-manager-1.26.16-1.el8.x86_64
subscription-manager-rhsm-certificates-1.26.16-1.el8.x86_64

How reproducible:
 * always

Steps to Reproduce:
1. get a RHEL-8.2 machine (targeted policy is active)
# service rhsm start
Redirecting to /bin/systemctl start rhsm.service
# service rhsm-facts start
Redirecting to /bin/systemctl start rhsm-facts.service
# ps -efZ | grep rhsm[-]
system_u:system_r:unconfined_service_t:s0 root 5048    1  0 13:21 ?        00:00:00 /usr/libexec/platform-python /usr/libexec/rhsm-service
system_u:system_r:unconfined_service_t:s0 root 5064    1  0 13:21 ?        00:00:00 /usr/libexec/platform-python /usr/libexec/rhsm-facts-service
#

Expected results:
 * the services are confined (either rhsmcertd_t or another SELinux domain)

Comment 1 Milos Malik 2020-06-10 17:49:57 UTC
Are these services functionally different from the rhsmcertd service?

I assume that we can use the rhsmcertd policy for them:

# chcon -t rhsmcertd_exec_t /usr/libexec/rhsm-service
# chcon -t rhsmcertd_exec_t /usr/libexec/rhsm-facts-service

They do not trigger any SELinux denials and they seem to run without problems:

# ps -efZ | grep rhsm[-]
system_u:system_r:rhsmcertd_t:s0 root       5170       1  0 13:42 ?        00:00:00 /usr/libexec/platform-python /usr/libexec/rhsm-service
system_u:system_r:rhsmcertd_t:s0 root       5212       1  0 13:42 ?        00:00:00 /usr/libexec/platform-python /usr/libexec/rhsm-facts-service

    Confine rhsm service and rhsm-facts service as rhsmcertd_t

    Rhsm service and rhsm-fact service run as unconfined_t. Use existing
    rhsmcertd_t policy to confine rhsm service and rhsm-facts service as
    rhsmcertd_t. Label binary files, which execute systemd daemon.
