Branch: refs/heads/calm-down-recvmmsg-on-eof Home: https://github.com/kronosnet/kronosnet Commit: 457f959d8bc0af521cb15050c6a4347f5728aa4e https://github.com/kronosnet/kronosnet/commit/457f959d8bc0af521cb15050c6a43… Author: Christine Caulfield <ccaulfie(a)redhat.com> Date: 2020-01-16 (Thu, 16 Jan 2020) Changed paths: M libknet/transport_common.c M libknet/transport_sctp.c Log Message: ----------- [rx] Don't return 512 EOF messagese from _recvmmsg If recvmsg() returns 0 for EOF then it's going to do so until the error is rectified or read with getsockopt(). But the _recvmmsg() wrapper keeps reading until the vector is full thus returning a block of 512 EOF messages all of which the caller has to plough through. This patch causes _recvmmsg() to return as soon as it has got the first EOF so the the caller can deal with it in good time and not spin looking at the same thing over and over again. I've also fixed a couple of typos in related comments
