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-3.2-1.el7
Doc Type: Rebase: Bug Fixes and Enhancements
Doc Text:
_systemtap_ rebased to version 3.2 The *SystemTap* utility has been updated to upstream version 3.2. Notable enhancements include: * Support for extraction of matched regular expression has been added. * Probe aliases for accepting input from the standard input have been added. * Translator diagnostics have been improved. * Support for the new `statx` system call has been added. * A new string function `strpos()` for detecting substring position has been added to the stap language. Additionally, this update fixes the following bugs: * Previously, the statistics extractor functions `@min()` and `@max()` returned incorrect values. As a consequence, scripts relying on these functions did not work properly. The `@min()` and `@max()` functions have been fixed to return the correct maximum and minimum values. As a result, the affected scripts now work as expected. * Previously, some kernel tracepoints were inconsistently listed with the `stap -L` command, even when they could not be probed. *SystemTap* has been fixed so that the listed and probe-able tracepoint sets match again. * The `netdev.receive` probe has been fixed and can collect data again. * The example script `nettop.stp` affected by the broken `netdev.receive` probe again works as expected. Note that the kernel version in Red Hat Enterprise Linux does not support extended Berkeley Packet Filter (eBPF), and consequently the related upstream *SystemTap* features are not available.

Able to see the enteries in the format :

N@OP where
N maybe any one of -1, -2, -4, -8, 1, 2, 4, 8
OP maybe in any one of the following formats
iNUM or i-NUM
REG or %rREG
NUM(REG) or -NUM(REG) or NUM(%rREG) or -NUM(%rREG)
REG,REG or %rREG,%rREG
where NUM is any numeric constant and REG is a register
index (0 to 31).
