Note: This bug is displayed in read-only format because
the product is no longer active in Red Hat Bugzilla.
RHEL Engineering is moving the tracking of its product development work on RHEL 6 through RHEL 9 to Red Hat Jira (issues.redhat.com). If you're a Red Hat customer, please continue to file support cases via the Red Hat customer portal. If you're not, please head to the "RHEL project" in Red Hat Jira and file new tickets here. Individual Bugzilla bugs in the statuses "NEW", "ASSIGNED", and "POST" are being migrated throughout September 2023. Bugs of Red Hat partners with an assigned Engineering Partner Manager (EPM) are migrated in late September as per pre-agreed dates. Bugs against components "kernel", "kernel-rt", and "kpatch" are only migrated if still in "NEW" or "ASSIGNED". If you cannot log in to RH Jira, please consult article #7032570. That failing, please send an e-mail to the RH Jira admins at rh-issues@redhat.com to troubleshoot your issue as a user management inquiry. The email creates a ServiceNow ticket with Red Hat. Individual Bugzilla bugs that are migrated will be moved to status "CLOSED", resolution "MIGRATED", and set with "MigratedToJIRA" in "Keywords". The link to the successor Jira issue will be found under "Links", have a little "two-footprint" icon next to it, and direct you to the "RHEL project" in Red Hat Jira (issue links are of type "https://issues.redhat.com/browse/RHEL-XXXX", where "X" is a digit). This same link will be available in a blue banner at the top of the page informing you that that bug has been migrated.
Cloning to RHEL 8 as it happens there too.
+++ This bug was initially created as a clone of Bug #2077777 +++
Description of problem:
insights-client validates the GPG signatures of files by running `gpg`; this causes some SELinux denials:
audit: type=1400 audit(1650615650.790:4): avc: denied { read } for pid=22197 comm="gpg" name="pubring.kbx" dev="vda4" ino=16798216 scontext=system_u:system_r:insights_client_t:s0 tcontext=unconfined_u:object_r:admin_home_t:s0 tclass=file permissive=0
audit: type=1400 audit(1650615650.810:5): avc: denied { read } for pid=22197 comm="gpg" name="pubring.kbx" dev="vda4" ino=16798216 scontext=system_u:system_r:insights_client_t:s0 tcontext=unconfined_u:object_r:admin_home_t:s0 tclass=file permissive=0
audit: type=1400 audit(1650615650.843:6): avc: denied { getattr } for pid=22197 comm="gpg" path="/root/.gnupg/trustdb.gpg" dev="vda4" ino=16799856 scontext=system_u:system_r:insights_client_t:s0 tcontext=unconfined_u:object_r:admin_home_t:s0 tclass=file permissive=0
audit: type=1400 audit(1650615650.843:7): avc: denied { write } for pid=22197 comm="gpg" name=".gnupg" dev="vda4" ino=16798004 scontext=system_u:system_r:insights_client_t:s0 tcontext=unconfined_u:object_r:admin_home_t:s0 tclass=dir permissive=0
`gpg` tries to create its own homedir (~/.gnupg by default): this of course fails in case insights-client is invoked not manually, but e.g. by cockpit (from the subscription-manager plugin) or as systemd service.
Possible solutions to avoid this:
- create a temporary directory for `gpg`, and pass it with `--homedir` to all the `gpg` invocations
- use a Python library for validating signatures -- python3-gpg, i.e. the Python binding of GPGME [1], seems a potential good candidate, as it is already shipped in BaseOS (even in RHEL 8)
