notification from mac80211, then inform uCode to switch to RTS/CTS
through RXON command.

When resuming from hibernate or suspend,
the status of the rfkill switch isn't
known since it might have been toggled
while the system was asleep. Therefore,
we need to read out the status at resume
time to make sure the system knows about
an up-to-date status.

The rate table in the bcast LQ is computed only when the station is
allocated, and chooses the lowest rate for the band. Because of when this
occurs, this is the 2.4 GHz band and uses the 0x420a (CCK, 1 Mbps) rate. In 5 GHz
beaconing mode, this rate will prevent beacons from being sent and any other
packets from being received.
We can fix this by re-initializing the bcast station's LQ command when the
channel is changed.

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.

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.

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.

commit 3474ad635db371b0d8d0ee40086f15d223d5b6a4
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.

CONFIG_NF_CT_ACCT has been deprecated for awhile and
was originally scheduled for removal by 2.6.29.
Removing support for this config option also stops
this deprecation warning message in the kernel log.

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:

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):
F: tcp_sendmsg1 -EPIPE: sk=ffff81000bda00d0, sport=49847, old_state=7, new_state=7, sk_err=0, sk_shutdown=3

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

[<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.

Fix the bundle validation code to not assume having a valid policy.
When we have multiple transformations for a xfrm policy, the bundle
instance will be a chain of bundles with only the first one having
the policy reference. When policy_genid is bumped it will expire the
first bundle in the chain which is equivalent of expiring the whole
chain.

In preparation for a TX power setting interface in the nl80211, change the
.set_tx_power function to use mBm units instead of dBm for greater accuracy and
smaller power levels.
Also, already in advance move the tx_power_setting enumeration to nl80211.
This change affects the .tx_set_power function prototype. As a result, the
corresponding changes are needed to modules using it. These are mac80211,
iwmc3200wifi and rndis_wlan.

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.

...but ieee80211_bss_info_change_notify is allowed to sleep. A driver
taking advantage of that allowance can cause a scheduling while

this patch is implementing IP_NODEFRAG option for IPv4 socket.
The reason is, there's no other way to send out the packet with user
customized header of the reassembly part.

For z/VM guest operating systems, OSX CHPIDs can only be used, if
LPAR and z/VM userID are explicitly authorized through the Service
Element. Issue a message if this SE-authorization is missing.

Turning on memory debugging showed there could be page breaks in
hardware headers. OSA does not allow this so we had to add code
to bounce the header in case there is a page break. This patch also
fixes a problem in case the skb->data part of a fragmented skb
spreads multiple pages.

The function qeth_free_buffer_pool is called _after_ the per-card
debug area has been released. This debug message is not all that
usefull anyway, and thus gets removed.

This patch removes the qerr debug area. Most info that goes in here is logged
to the card's local debug area already, those duplicates are removed. All other
elements are moved to the card's local debug area.

This patch removes the misc debug area. Instead of logging the entire skb
we just log a pointer to it into the card's local debug area in
qeth_core_get_next_skb. Other then that, this debug area is not used anywhere.

This patch removes the sense debug area completely. Despite the name this
debug area makes no sense at all because it's unused completely. Ouch.

This patch removes the qeth_trace debug area. All relevant data is logged into
either qeth_setup or into each card's own debug area. Superfluous information
(such as the card number when logging into the card's own debug area) is
removed without replacement.

This patch adds a debug area for each qeth card. This debug area will replace
various other debug areas that are global for all cards handled by the device
driver. On crash dump analysis this makes life easier when trying to find out
what's going on with an interface. Also, the forest of debug areas for this
device driver is significantly cleared up.

This patch decouples qeth_dbf_longtext from qeth's static debug array. The
function only uses one member anyway.
