https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D229384 --- Comment #16 from commit-hook@freebsd.org --- A commit references this bug: Author: loos Date: Mon Aug 20 01:01:34 UTC 2018 New revision: 338081 URL: https://svnweb.freebsd.org/changeset/base/338081 Log: MFC r312770 and r337854: After the in_control() changes in r257692, an existing address is (intentionally) deleted first and then completely added again (so all the events, announces and hooks are given a chance to run). This cause an issue with CARP where the existing CARP data structure is removed together with the last address for a given VHID, which will cause a subsequent fail when the address is later re-added. This change fixes this issue by adding a new flag to keep the CARP data structure when an address is not being removed. There was an additional issue with IPv6 CARP addresses, where the CARP da= ta structure would never be removed after a change and lead to VHIDs which cannot be destroyed.
