Patch Set 2: Code-Review-1 (1 comment) Patchset: PS2: This is only half-working for me. Triggered by https://github.com/OpenVPN/openvpn/issues/890 I have built a testbed to reproduce this. - ssh -R *:12345:conn-test-server.openvpn.org:51194 $linuxserver - on the linux server, run `openvpn --client --remote 127.0.0.5 51194 tcp ... --route 1.1.1.1 255.255.255.255 net_gateway` it will do both gateway lookups, and setenv `net_gateway` accordingly ``` 2025-11-15 17:57:26 net_route_v4_best_gw query: dst 0.0.0.0 2025-11-15 17:57:26 net_route_v4_best_gw result: via 194.97.140.30 dev enp0s18 2025-11-15 17:57:26 net_route_v4_best_gw query: dst 127.0.0.5 2025-11-15 17:57:26 net_route_v4_best_gw result: via 0.0.0.0 dev lo 2025-11-15 17:57:26 GDG6: remote_host_ipv6=n/a 2025-11-15 17:57:26 net_route_v6_best_gw query: dst :: 2025-11-15 17:57:26 net_route_v6_best_gw result: via 2001:608:0:814::ffff dev enp0s18 2025-11-15 17:57:26 net_route_v6_best_gw query: dst :: 2025-11-15 17:57:26 net_route_v6_best_gw result: via 2001:608:0:814::ffff dev enp0s18 ``` but the gateway address used for `net_gateway` is the one from the second lookup ``` 2025-11-15 18:03:45 net_route_v4_add: 1.1.1.1/32 via 0.0.0.0 dev [NULL] table 0 metric -1 2025-11-15 18:03:45 sitnl_send: rtnl: generic error (-19): No such device 2025-11-15 18:03:45 ERROR: Linux route add command failed ``` so we might need to store the `ngi` in the `struct route-list` as well, and depending on use case use `rgi` or `ngi` - for the bypass-routes, we want `rgi`, for `get_special_addr()` use case, we want `ngi`... right? -- To view, visit http://gerrit.openvpn.net/c/openvpn/+/1222?usp=email To unsubscribe, or for help writing mail filters, visit http://gerrit.openvpn.net/settings?usp=email Gerrit-MessageType: comment Gerrit-Project: openvpn Gerrit-Branch: master Gerrit-Change-Id: I16d90221d0a75193035253817ff195f6da9dc0b3 Gerrit-Change-Number: 1222 Gerrit-PatchSet: 2 Gerrit-Owner: mrbff <[email protected]> Gerrit-Reviewer: cron2 <[email protected]> Gerrit-Reviewer: flichtenheld <[email protected]> Gerrit-Reviewer: plaisthos <[email protected]> Gerrit-CC: openvpn-devel <[email protected]> Gerrit-Attention: plaisthos <[email protected]> Gerrit-Attention: flichtenheld <[email protected]> Gerrit-Attention: mrbff <[email protected]> Gerrit-Comment-Date: Sat, 15 Nov 2025 17:07:03 +0000 Gerrit-HasComments: Yes Gerrit-Has-Labels: Yes
