nginx.git/src/stream/ngx_stream.c, branch release-1.29.7 nginx The "multipath" parameter of the "listen" directive. 2026-03-18T21:13:51+00:00 Sergey Kandaurov pluknet@nginx.com 2025-10-16T15:22:56+00:00 920dc099c130e0ea23eb36becd157a95901aa5a2 When configured, it enables Multipath TCP support on a listen socket. As of now it works on Linux starting with Linux 5.6 and glibc 2.32, where it is enabled with an IPPROTO_MPTCP socket(2) protocol. To avoid EADDRINUSE errors in bind() and listen() when transitioning between sockets with different protocols, SO_REUSEPORT is set on both sockets. See f7f1607bf for potential implications. Based on previous work by Maxime Dourov and Anthony Doeraene.

Events: moved sockets cloning to ngx_event_init_conf(). 2018-07-12T16:50:02+00:00 Maxim Dounin mdounin@mdounin.ru 2018-07-12T16:50:02+00:00 751bdd3bb2b6ff54be09c37ff328f258fed520fb Previously, listenings sockets were not cloned if the worker_processes directive was specified after "listen ... reuseport". This also simplifies upcoming configuration check on the number of worker connections, as it needs to know the number of listening sockets before cloning.
