Created attachment 731215 [details] Proposed patch Description of problem: corosync.conf: ... uidgid { uid: nonexistinguser } No error is shown (even according to code it should) Version-Release number of selected component (if applicable): Flatiron How reproducible: 100% "Unit test": https://github.com/jfriesse/csts/blob/master/tests/uidgid-parse.sh Actual results: Fail ($? != 0) Expected results: Success ($? == 0) Additional info:
Verified with uidgid-parse.sh: FAIL on corosync-1.4.1-15.el6.x86_64 (RHEL6.4) PASS on corosync-1.4.1-17.el6.x86_64 (RHEL6.5) Sep 11 18:10:06 virt-014 corosync[5211]: [corosy] The 'nonexistinguid' user is not found in /etc/passwd, please read the documentation. Sep 11 18:10:06 virt-014 corosync[5211]: [MAIN ] Corosync Cluster Engine exiting with status 1 at mainconfig.c:622. Just a question: does it really check only /etc/passwd or is it also friendly to other system user entries (like ldap users) and the message is slightly misleading?
It calls getpwnam_r, so second option is true.
