It doesn't, however, enable assignment of multiple addresses in the sense requested at: https://bugs.passt.top/show_bug.cgi?id=47 because the addresses still need to be present on the host, and the "outer" address isn't selected depending on the address used inside the container - operation without a gateway address. This is related to: https://bugs.passt.top/show_bug.cgi?id=49 but Wireguard endpoints established outside the container can't be used yet as outbound interface (without the workaround reported there) for a number of reasons I'm still investigating. In any case, the correct route is now configured in the container, even without a default gateway on the corresponding host route, so we're a bit closer to support that configuration out of the box. v2: - in 3/10, repeat the netlink request once for each RTM_NEWROUTE we're going to send as part of the request: routes might depend on each other, and this is a somewhat rudimentary, but seemingly robust approach to insert all the routes we can insert, without explicitly calculating dependencies - Cc: Andrea, reporter for the issue fixed in 4/10 Stefano Brivio (10): netlink: Fix comment about response buffer size for nl_req() pasta: Improve error handling on failure to join network namespace netlink: Add functionality to copy routes from outer namespace conf: --config-net option is for pasta mode only conf, pasta: With --config-net, copy all routes by default Revert "conf: Adjust netmask on mismatch between IPv4 address/netmask and gateway" conf: Don't exit if sourced default route has no gateway netlink: Add functionality to copy addresses from outer namespace conf, pasta: With --config-net, copy all addresses by default passt.h: Fix description of pasta_ifi in struct ctx conf.c | 81 +++++++++++++++++++------------- netlink.c | 135 +++++++++++++++++++++++++++++++++++++++++------------- netlink.h | 13 ++++-- passt.1 | 25 +++++++++- passt.h | 8 +++- pasta.c | 26 +++++++---- 6 files changed, 207 insertions(+), 81 deletions(-) -- 2.39.2
