Both NetBSD and OpenBSD have added checks to allow for neighbors on routes marked RTF_CLONING, but FreeBSD dropped this routing flag a while ago. As such, the only similar check that can be made is against the absence of RTF_STATIC. Attached is a patch that implements this and allows dhcpcd-6.5.1 to work entirely on FreeBSD. -- You are receiving this mail because: You are the assignee for the bug.
