From cc9d16758be69c0ca16eb7f11b31a07945cf427e Mon Sep 17 00:00:00 2001 From: Stefano Brivio Date: Sun, 14 May 2023 19:12:09 +0200 Subject: conf, pasta: With --config-net, copy all addresses by default Use the newly-introduced NL_DUP mode for nl_addr() to copy all the addresses associated to the template interface in the outer namespace, unless --no-copy-addrs (also implied by -a) is given. This option is introduced as deprecated right away: it's not expected to be of any use, but it's helpful to keep it around for a while to debug any suspected issue with this change. This is done mostly for consistency with routes. It might partially cover the issue at: https://bugs.passt.top/show_bug.cgi?id=47 Support multiple addresses per address family for some use cases, but not the originally intended one: we'll still use a single outbound address (unless the routing table specifies different preferred source addresses depending on the destination), regardless of the address used in the target namespace.
