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.

Fixed In Version: systemtap-2.7-2.el6
Doc Type: Bug Fix
Doc Text:
The systemtap's system call tapset-library unconditionally included support for the "execveat" system call, even though "execveat" did not exist in Red Hat Enterprise Linux 6 kernels. Consequently, system call probing scripts could fail with a semantic error. With this update, "execveat" is treated conditionally, and the scripts no longer fail in this situation.

Description Martin Cermak 2015-02-24 17:07:06 UTC 
The rhel6 kernel (2.6.32-536.el6) doesn't have the execveat syscall. Due to this [nd]_syscalls-detailed.stp fails:

=======
Running ./buildok/syscalls-detailed.stp
starting ./buildok/syscalls-detailed.stp 
spawn2 ./buildok/syscalls-detailed.stp 
spawn ./buildok/syscalls-detailed.stp
semantic error: while resolving probe point: identifier 'syscall' at ./buildok/syscalls-detailed.stp:345:7
        source: probe syscall.execveat, syscall.compat_execveat ?
                      ^

semantic error: no match

Pass 2: analysis failed.  [man error::pass2]
=======

Please, backport upstream commit 86c7acd.
