[kronosnet/kronosnet] d2a30a: [udp] don't make socket spin if a network I/F is down
by Chrissie Caulfield 24 Jan '20

Branch: refs/heads/dont-spin-enetunreach Home: https://github.com/kronosnet/kronosnet Commit: d2a30ac0135c15eebce25a89f943e9062e1b3f6c https://github.com/kronosnet/kronosnet/commit/d2a30ac0135c15eebce25a89f943e… Author: Christine Caulfield <ccaulfie(a)redhat.com> Date: 2020-01-24 (Fri, 24 Jan 2020) Changed paths: M libknet/transport_udp.c Log Message: ----------- [udp] don't make socket spin if a network I/F is down UDP treats ENETUNREACH as a temporary error and just retries, but this causes the TX thread to spin just doing sendto() therefore blocking all other traffic. (To reproduce this try starting corosync with 2 links configured in corosync.conf but only one of them configured to the 'right' address - it will spin in a tight loop and need to be killed with -9) SCTP does not seem to suffer from this.

[kronosnet/kronosnet] 610812: [rx] Don't return 512 EOF messages from _recvmmsg
by Fabio M. Di Nitto 24 Jan '20

24 Jan '20

Branch: refs/heads/sctp-fixes Home: https://github.com/kronosnet/kronosnet Commit: 6108120eb3a646b7d504f58ed43dd8ecf3513baa https://github.com/kronosnet/kronosnet/commit/6108120eb3a646b7d504f58ed43dd… Author: Christine Caulfield <ccaulfie(a)redhat.com> Date: 2020-01-24 (Fri, 24 Jan 2020) Changed paths: M libknet/transport_common.c M libknet/transport_sctp.c Log Message: ----------- [rx] Don't return 512 EOF messages 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 Commit: d2064731e8b778a9508fddaa1693ac22fec39ef8 https://github.com/kronosnet/kronosnet/commit/d2064731e8b778a9508fddaa1693a… Author: Christine Caulfield <ccaulfie(a)redhat.com> Date: 2020-01-24 (Fri, 24 Jan 2020) Changed paths: M libknet/transport_common.c Log Message: ----------- [tx] Don't Clear out msghdr for all transports. When sending a message to multiple links, if one of those links is not connection-oriented then msg_name & msg_namelen would be cleared, thus breaking the send to any subsequent non-connection-oriented links. So now, if we need to clear out msg_name & msg_namelen, we take a copy of the msghdr and edit that instead, Commit: 72156af66f90daf6e44010dd001fd561f49054e6 https://github.com/kronosnet/kronosnet/commit/72156af66f90daf6e44010dd001fd… Author: Fabio M.

Di Nitto <fdinitto(a)redhat.com> Date: 2020-01-24 (Fri, 24 Jan 2020) Changed paths: M libknet/transport_sctp.c Log Message: ----------- [sctp] major surgery to use only SCTP events to determine socket status - drop concept of on_connected_epoll to determine if socket is ready or not - provide much better debugging output at all levels - incorporate fix from Xin Long <lxin(a)redhat.com> to gather socket status at the right time - deal with a recent kernel change on SCTP socket that broke knet (from rhel7): [net] sctp: allow delivering notifications after receiving SHUTDOWN Signed-off-by: Fabio M.
