occurs, this is the 2.4 GHz band and uses the 0x420a (CCK, 1 Mbps) rate. In 5 GHz

Using RTS/CTS will better protect the inner exchange from interference,
especially in highly-congested environment, it also prevent uCode encounter

iwlwifi: apply filter flags directly
broke multicast. The reason, it turns out, is that
the code previously checked if ALLMULTI _changed_,
which the new code no longer did, and normally it
_never_ changes. Had somebody changed it manually,
the code prior to my patch there would have been
broken already.
The reason is that we always, unconditionally, ask
the device to pass up all multicast frames, but the
new code made it depend on ALLMULTI which broke it
since now we'd pass up multicast frames depending
on the default filter in the device, which isn't
necessarily what we want (since we don't program it
right now).
Fix this by simply not checking allmulti as we have
allmulti behaviour enabled already anyway.

i've found that tcp_close() can be called for an already closed
socket, but still sends reset in this case (tcp_send_active_reset())
which seems to be incorrect. Moreover, a packet with reset is sent
with different source port as original port number has been already
cleared on socket. Besides that incrementing stat counter for
LINUX_MIB_TCPABORTONCLOSE also does not look correct in this case.
Initially this issue was found on 2.6.18-x RHEL5 kernel, but the same
seems to be true for the current mainstream kernel (checked on
2.6.35-rc3). Please, correct me if i missed something.
How that happens:
1) the server receives a packet for socket in TCP_CLOSE_WAIT state
that triggers a tcp_reset():

2) After that the process (socket owner) tries to write something to
that socket and "inet_autobind" sets a _new_ (which differs from
the original!) port number for the socket:

3) sendmsg fails at last with -EPIPE (=> 'write' returns -EPIPE in userspace):

if ((err = sk_stream_wait_connect(sk, &timeo)) != 0) {
if (f_d && (err == -EPIPE)) {
printk("F: tcp_sendmsg1 -EPIPE: sk=%p, sport=%u, old_state=%d, new_state=%d, "

sk, ntohs(inet_sk(sk)->sport), old_state, sk->sk_state,
sk->sk_err, sk->sk_shutdown);
dump_stack();
}
goto out_err;
}
}
...
4) Then the process (socket owner) understands that it's time to close
that socket and does that (and thus triggers sending reset packet):
Call Trace:
...

So, in brief:
* a received packet for socket in TCP_CLOSE_WAIT state triggers
tcp_reset() which clears inet_sk(sk)->num and put socket into
TCP_CLOSE state
* an attempt to write to that socket forces inet_autobind() to get a
new port (but the write itself fails with -EPIPE)
* tcp_close() called for socket in TCP_CLOSE state sends an active
reset via socket with newly allocated port
This adds an additional check in tcp_close() for already closed
sockets. We do not want to send anything to closed sockets.
