2010-08-07O2net: Disallow o2net accept connection request from itself.Tristan Ye1-5/+12
Currently, o2net_accept_one() is allowed to accept a connection from listening node itself, such a fake connection will not be successfully established due to no handshake detected afterwards, and later end up with triggering connecting worker in a loop. We're going to fix this by treating such connection request as 'invalid', since we've got no chance of requesting connection from a node to itself in a OCFS2 cluster. The fix doesn't hurt user's scan for o2net-listener, it always gets a successful connection from userpace.

2008-04-18ocfs2: Reconnect after idle time out.Tao Ma1-15/+36
Currently, o2net connects to a node on hb_up and disconnects on hb_down and net timeout. It disconnects on net timeout is ok, but it should attempt to reconnect back. This is because sometimes nodes get overloaded enough that the network connection breaks but the disk hb does not. And if we get into that situation, we either fence (unnecessarily) or wait for its disk hb to die (and sometimes hang in the process). So in this updated scheme, when the network disconnects, we keep attempting to reconnect till we succeed or we get a disk hb down event. If the other node is really dead, then we will eventually get a node down event. If not, we should be able to connect again and continue.

2007-02-07ocfs2: introduce sc->sc_send_lock to protect outbound outbound messagesZhen Wei1-0/+8
When there is a lot of multithreaded I/O usage, two threads can collide while sending out a message to the other nodes. This is due to the lack of locking between threads while sending out the messages. When a connected TCP send(), sendto(), or sendmsg() arrives in the Linux kernel, it eventually comes through tcp_sendmsg(). tcp_sendmsg() protects itself by acquiring a lock at invocation by calling lock_sock(). tcp_sendmsg() then loops over the buffers in the iovec, allocating associated sk_buff's and cache pages for use in the actual send. As it does so, it pushes the data out to tcp for actual transmission. However, if one of those allocation fails (because a large number of large sends is being processed, for example), it must wait for memory to become available. It does so by jumping to wait_for_sndbuf or wait_for_memory, both of which eventually cause a call to sk_stream_wait_memory(). sk_stream_wait_memory() contains a code path that calls sk_wait_event(). Finally, sk_wait_event() contains the call to release_sock(). The following patch adds a lock to the socket container in order to properly serialize outbound requests.
