can't be connected to 2.1June McEnroe I think this emulates SO_REUSEADDR, which for some reason doesn't work on PF_UNIX. If the socket exists, check if connect(2) works, rather than clobbering the socket being used by a still-running instance. 2020-11-21Clean up main loop loopsJune McEnroe 2020-11-20Add lazy client registration timeoutJune McEnroe I don't think this is worth adding a configuration option for since real clients will definitely accomplish registration faster than 10s and it's long enough to even type out manually for testing. 2020-11-16Only allow clients to AUTHENTICATE if using a certJune McEnroe Otherwise the successful authentication message can leak information to unauthenticated clients when both certificate and password authentication are enabled. 2020-11-16Set client sockets non-blockingJune McEnroe Except for during writes. This prevents pounce getting blocked on a client sending only a partial TLS record, for example. Writes still need to block because pounce doesn't have a way to resume them. (And it would do so by having a buffer, but sockets already have a send buffer, so what would be the point of that?) I don't think it should be a problem since outside of stateSync, writes only happen when poll returns POLLOUT. I feel like ideally SO_SNDLOWAT would be set to guarantee a full IRC message can always be written on POLLOUT, but since it's actually TLS records being sent, it's not obvious what the size would be. I'm also making an assumption here that tls_read returning TLS_WANT_POLLOUT is unlikely to happen, since I don't actually set pollfd.events based on that. I'm not sure how wanting to resume a tls_read after a POLLOUT could be cleanly handled. I'm just going to hope that if it does happen, the regular poll loop will eventually sort it out... 2020-11-14Swap localAccept parameter orderJune McEnroe 2020-11-14Only send shutdown QUIT and ERROR to registered clientsJune McEnroe 2020-11-14Make struct Client publicJune McEnroe 2020-11-13Wait for POLLIN to do client tls_handshakeJune McEnroe Otherwise a client could cause pounce to hang (since the sockets are left blocking) by opening a connection without handshaking! Oops, that's pretty bad. Since the sockets are still blocking, a hang can still be caused by a client sending a partial handshake then waiting. More fixes to follow. pounce is slightly protected from this when used with calico, as it applies a timeout to waiting for the ClientHello. 2020-11-13Use a fixed size pollfd array in calicoJune McEnroe My thinking here is that it's better to not allocate in response to incoming connections. This also just makes the code a little simpler. 2020-11-13Disallow / anywhere in server nameJune McEnroe 2020-11-12Check bounds of ClientHello extensions lengthJune McEnroe 2020-11-10Report paths in unveil errorsJune McEnroe 2020-10-24contrib/palaver: Use open_memstream instead of fmemopenJune McEnroe Somehow I never knew about this function.
