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.

_libreswan_ now supports IKEv2 MOBIKE This update introduces support for the IKEv2 Mobility and Multihoming (MOBIKE) protocol (RFC 4555) using the XFRM_MIGRATE mechanism through the "mobike=yes|no" option. MOBIKE enables seamless switching of networks, for example, Wi-Fi, LTE, and so on, without disturbing the IPsec tunnel.

Description Paul Wouters 2017-07-17 12:13:30 UTC
This document describes the MOBIKE protocol, a mobility and
   multihoming extension to Internet Key Exchange (IKEv2).  MOBIKE
   allows the IP addresses associated with IKEv2 and tunnel mode IPsec
   Security Associations to change.  A mobile Virtual Private Network
   (VPN) client could use MOBIKE to keep the connection with the VPN
   gateway active while moving from one address to another.  Similarly,
   a multihomed host could use MOBIKE to move the traffic to a different
   interface if, for instance, the one currently being used stops

This support requires a few recent fixes in the kernel. See associated bug for this status

> master upstream

Paul, I just get to this - do you have those test cases or any hint to test mobike support? I see that upstream test cases got updated with mobike=no but there are no mobike=yes test cases in master so far. BTW: ipsec.conf man page does not mention mobike option at all at the moment (3.22-2.el7).

Comment 7 Ondrej Moriš 2017-12-13 15:17:23 UTC
Moreover, from BZ#1460790#c4 I got an impression that MOBIKE libreswan client support is not yet done, or is it? I would like to use the following testing approach - libreswan server with mobike=yes, libreswan client from laptop having both wired and wireless connection with IPsec tunnel to server using wireless, then bringing down wireless connection should keep tunnel on using wired connection. Does it make sense?

Comment 8 Paul Wouters 2017-12-13 17:02:05 UTC
the client support is not yet in upstream or this build. Actually, the server side isn't in a public tree yet either and that one contains the test cases (using strongswan as client)

I'll see if mobike lands in master today or tomorrow. If not, I will attach the test cases here.

Note that you also need a patched kernel for this to work, as the mobike fixes have not yet been put into the rhel-7.5.0 kernel either
