680788aca3 iwlwifi: add a mechanism to disable plcp error checking
For some devices, especially the upcoming new devices, the plcp error
rate is different. Before the correct error rate can be determine, also
for the debugging purpose; add the mechanism to disable plcp error checking
which cause radio reset happen.

4e3243f549 iwlwifi: name change from signal protection flag
This bit need to be set for both RTS/CTS or CTS-to-self protection, if
CTS-to-self is used, then uCode will  check the RXON_FLG_SELF_CTS_EN
status. Change the name from TX_CMD_FLG_RTS_CTS_MSK to TX_CMD_FLAG_PROT_REQUIRE_MSK
to match the behavior of the bit setting.

Also update comments to reflect which hardware uses which of the TX command
flags.

062bee448b iwlwifi: set TX_CMD_FLAG_PROT_REQUIRE_MSK in tx_flag
When building tx command, always set TX_CMD_FLAG_PROT_REQUIRE_MSK
for 5000 series and up.

Without setting this bit the firmware will not examine the RTS/CTS setting
and thus not send traffic with the appropriate protection. RTS/CTS is is
required for HT traffic in a noisy environment where, without this setting,
connections will stall on some hardware as documented in the patch that
initially attempted to address this:

    iwlwifi: Fix throughput stall issue in HT mode for 5000

    Similar to 6000 and 1000 series, RTS/CTS is the recommended
    protection mechanism for 5000 series in HT mode based on the HW design.
    Using RTS/CTS will better protect the inner exchange from interference,
    especially in highly-congested environment, it also prevent uCode encounter
    TX FIFO underrun and other HT mode related performance issues.

For 3945 and 4965, different flags are used for RTS/CTS or CTS-to-Self
protection.

d1e89f37de iwlwifi: fix multicast
commit 3474ad635d
Author: Johannes Berg <johannes.berg@intel.com>
Date:   Thu Apr 29 04:43:05 2010 -0700

    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.

565b7b2d2e tcp: do not send reset to already closed sockets
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():

Call Trace:

...  // (sk_state == TCP_CLOSE_WAIT here)

        if(th->rst) {
                tcp_reset(sk);
                goto discard;
        }

     inet_put_port
      __inet_put_port
       inet_sk(sk)->num = 0;

   sk->sk_shutdown = SHUTDOWN_MASK;

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:

 Call Trace:

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

 [<ffffffff800622dd>] tracesys+0xd5/0xe0

tcp_sendmsg()
...
        /* Wait for a connection to finish. */
        if ((1 << sk->sk_state) & ~(TCPF_ESTABLISHED | TCPF_CLOSE_WAIT)) {
                int old_state = sk->sk_state;
                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_err=%d, sk_shutdown=%d\n",
                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:
...
 [<ffffffff80032077>] dev_queue_xmit+0x343/0x3d6
 [<ffffffff80034698>] ip_output+0x351/0x384

 [<ffffffff8001eff6>] sys_close+0x85/0xc7
 [<ffffffff800622dd>] tracesys+0xd5/0xe0

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.

a185045c8d at76c50x-usb: Extract bssid from authentication frame
The driver at76c50x-usb is unable to authenticate with an AP since
kernel 2.6.31 for the following reason: The join command of the firmware
needs to be sent with the right bssid before any transmission can start.
Before kernel 2.6.31 mac80211 informed its drivers about the changing
bssid early enough for at76c50x-usb but during the development of 2.6.31
mac80211's behaviour changed. Now a new bssid is set after the
association.

This patch changes the tx routine of the driver at76c50x-usb in such a
way that a new bssid is extracted from an authentication frame and the
join command with that bssid is processed.

41b4b289ad at76c50x-usb: Move function at76_join() several lines up
This patch does a simple code move of at76_join() so that
at76_mac80211_tx() follows at76_join() in the driver's source file.

This is a preparatory patch for the following patch where we need
to call at76_join() from at76_mac80211_tx() in order to
authenticate successfully with a bssid.

c937019761 mac80211: avoid scheduling while atomic in mesh_rx_plink_frame
While mesh_rx_plink_frame holds sta->lock...

mesh_rx_plink_frame ->
	mesh_plink_inc_estab_count ->
		ieee80211_bss_info_change_notify

...but ieee80211_bss_info_change_notify is allowed to sleep.  A driver
taking advantage of that allowance can cause a scheduling while
atomic bug.  Similar paths exist for mesh_plink_dec_estab_count,
so work around those as well.

http://bugzilla.kernel.org/show_bug.cgi?id=16099

Also, correct a minor kerneldoc comment error (mismatched function names).

38000a94a9 sky2: enable rx/tx in sky2_phy_reinit()
sky2_phy_reinit is called by the ethtool helpers sky2_set_settings,
sky2_nway_reset and sky2_set_pauseparam when netif_running.

However, at the end of sky2_phy_init GM_GP_CTRL has GM_GPCR_RX_ENA and
GM_GPCR_TX_ENA cleared. So, doing these commands causes the device to
stop working:

$ ethtool -r eth0
$ ethtool -A eth0 autoneg off

Fix this issue by enabling Rx/Tx after running sky2_phy_init in
sky2_phy_reinit.
