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.

Red Hat Product Errata RHBA-2017:2101 0 normal SHIPPED_LIVE libreswan bug fix and enhancement update 2017-08-01 16:07:26 UTC

Description Paul Wouters 2017-06-09 22:59:07 UTC
Description of problem:

"tunnel-XXXX" #768: payload (ISAKMP_NEXT_v2CERT) unexpectedly repeated. Message dropped.

This affects all versions of libreswan up to 3.18, so RHEL-7.3 packages have this issue as well. All versions of openswan are affected as well.

The current (prerelease) build for RHEL-7.4 which is based on 3.20 contains the fix for this issue.

Comment 1 Paul Wouters 2017-06-09 23:00:57 UTC
The code change is in ikev2.c:

Old code:

static const lset_t repeatable_payloads = P(N) | P(D) | P(CP) | P(V); 

New code:

static const lset_t repeatable_payloads = P(N) | P(D) | P(CP) | P(V) | P(CERT) | P(CERTREQ);

Comment 10 Ondrej Moriš 2017-06-22 07:38:57 UTC
Cannot reproduce this issue. Verified SanityOnly with libreswan-3.20-3.el7.
