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.

Description Robbie Harwood 2019-02-19 19:01:55 UTC

+++ This bug was initially created as a clone of Bug #1674501 +++

Description of problem:
Upstream test suite, namely "BASIC Fail Second User" test is failing on s390x. No failures appear on x86_64, aarch64 or ppc64le.

--- Additional comment from Joe Orton on 2019-02-19 03:56:48 EST ---

mod_auth_gssapi is using:

    AP_INIT_FLAG("GssapiPublishErrors", ap_set_flag_slot,
                 (void *)APR_OFFSETOF(struct mag_config, enverrs), OR_AUTHCFG,
                 "Publish GSSAPI Errors in Envionment Variables"),

but enverrs is a bool:

    bool enverrs;

ap_set_flag_slot() requires a variable with sizeof(int) whereas it looks like sizeof(bool) is not fixed by C99, only "big enough to store one bit".  On x86_64 sizeof(bool) is sizeof(char) anyway, so it's broken everywhere.

The simplest fix would be to change envvers to type int.

--- Additional comment from Joe Orton on 2019-02-19 04:04:39 EST ---

The other use of ap_set_flag_slot in this module:

    AP_INIT_FLAG("GssapiImpersonate", ap_set_flag_slot,
          (void *)APR_OFFSETOF(struct mag_config, s4u2self), OR_AUTHCFG,
               "Do impersonation call (S4U2Self) "
               "based on already authentication username"),

also has the same problem; using either these directives may be splatting over other config fields in nasty ways depending on the struct padding.

Thanks Joe.  Posted fix upstream.
