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.

+++ This bug was initially created as a clone of Bug #1113441 +++

Description of problem:
The imtcp plugin supports TCP keep-alive, but unlike the imptcp and imrelp plugins, it doesn't allow to set additional keep-alive parameters.

Version-Release number of selected component (if applicable):
rsyslog-7.4.10-2.fc21

Steps to Reproduce:
Search the imtcp documentation for "keepalive".

Actual results:
tcp_keepalive_intvl, tcp_keepalive_probes, tcp_keepalive_time can't be set.

Expected results:
tcp_keepalive_intvl, tcp_keepalive_probes, tcp_keepalive_time can be set.

Additional info:
See tcp(7) man page.

This can be worked around by changing the system-wide settings in /proc/sys/net/ipv4/tcp_keepalive_*.

this is fixed in rsyslog v8, linking rebase issue

As all options are present in rebased version (KeepAlive.Probes, KeepAlive.Interval and KeepAlive.Time) setting this to post
