From 2d2831e3541c8ae3c84f17cfd1bf0a26f2027044 Mon Sep 17 00:00:00 2001 From: Rahat Mahmood <rahat@google.com> Date: Thu, 6 Jun 2019 15:03:44 -0700 Subject: Track and export socket state. This is necessary for implementing network diagnostic interfaces like /proc/net/{tcp,udp,unix} and sock_diag(7). For pass-through endpoints such as hostinet, we obtain the socket state from the backend. For netstack, we add explicit tracking of TCP states.
