[lwip-devel] [task #14395] recv of short buffer should eventually time out

[Joel Cunningham]

Follow-up Comment #7, task #14395 (project lwip):


if (NETCONNTYPE_GROUP(netconn_type(sock->conn)) == NETCONN_TCP) {
      LWIP_ASSERT("invalid copylen, len would underflow", len >= copylen);
      len -= copylen;
      if ((len <= 0) ||
          (p->flags & PBUF_FLAG_PUSH) ||
          (sock->rcvevent <= 0) ||
          ((flags & MSG_PEEK) != 0)) {
        done = 1;
      }
    } else {
      done = 1;
    }


Just looking at this code again (in lwip_recvfrom), but won't the check
against sock->rcvevent cause the done state to be set, which then exits the
loop preventing blocking after the recvmbox has been drained?
