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.

Doc Type: Enhancement
Doc Text:
.`sshd_config:ClientAliveCountMax=0` disables connection termination Setting the SSHD configuration option `ClientAliveCountMax` to `0` now disables connection termination. This aligns the behavior of this option with the upstream. As a consequence, OpenSSH no longer disconnects idle SSH users when it reaches the timeout configured by the `ClientAliveInterval` option.

Description Steve Outteridge 2021-10-20 08:16:44 UTC
Description of problem:


Concerning RHEL 7 and 8, is it planned that this patch :

openssh patch for sshd_config:ClientAliveCountMax=0 disable the connection killing behaviour

https://anongit.mindrot.org/openssh.git/commit/?id=69334996ae203c51c70bf01d414c918a44618f8e

Be integrated in a future version of the openssh package (openssh-server)?

I can see it in bsd release:

https://ftp.openbsd.org/pub/OpenBSD/OpenSSH/portable/ChangeLog

But not in Red Hat change logs:

https://access.redhat.com/downloads/content/openssh-server/8.0p1-10.el8/x86_64/fd431d51/package-changelog

Comment 1 Dmitry Belyavskiy 2021-10-20 09:43:43 UTC
We currently don't have plans to integrate this patch into RHEL7/RHEL8 series.

*** Bug 2008339 has been marked as a duplicate of this bug. ***

Comment 9 Renaud Métrich 2021-12-09 11:29:45 UTC
I'm setting this as High/High because all customers implementing DISA compliance may hit this.
