Subject: [PATCH] WEP fields are incorrectly shown to be INSIDE snap in the doc

>If encryption is enabled, each fragment payload size is reduced by enough space
>to add the prefix and postfix (IV and ICV totalling 8 bytes in the case of WEP)
>So if you have 1500 bytes of payload with ieee->fts set to 500 without
>encryption it will take 3 frames.  With WEP it will take 4 frames as the
>payload of each frame is reduced to 492 bytes.

Text is correct, but in picture (IV,payload,ICV) sits inside SNAP.
Patch corrects this.

Subject: [PATCH] ieee80211: Add TKIP crypt->build_iv

This patch adds ieee80211 TKIP build_iv() method to support hardwares
that can do TKIP encryption but relies on ieee80211 layer to build
the IV. It also changes the build_iv() interface to return the key
if possible after the IV is built (this is required by TKIP).

Subject: [PATCH] ieee80211: Add helpers for IBSS DFS handling

To support IEEE 802.11h in IBSS, an ibss_dfs field is added to struct
ieee80211_network. In IBSS, if one STA sends a beacon with DFS info
(for radar detection), all the other STAs should receive and store
this DFS.  All STAs should send the DFS as one of the information
element in the beacon they are scheduled to send (if possible) in
the future.

Since the ibss_dfs has variable length, it must be allocated
dynamically. ieee80211_network_reset() is added to clear the ibss_dfs
field. ieee80211_network_free() is also updated to free the ibss_dfs
field if it is not NULL.

Subject: [PATCH] ieee80211: Add 802.11h information element parsing

Added default handlers for various 802.11h DFS and TPC information
elements.  Moved all information elements into single location (called
from two places).  Added debug message with information on unparsed IEs
if debug_level set.  Added code to reset network IBSS DFS information
when appropriate.  Added code to invoke driver callback for 802.11h
ACTION STYPE.  Changed a few printk's to IEEE80211_DEBUG_MGMT.

From d86b5e0e6bf5980d3136ab4a855522143f2dcb5d Mon Sep 17 00:00:00 2001
From: Adrian Bunk
Date: Sat, 21 Jan 2006 00:46:55 +0100
Subject: [PATCH] net/: fix the WIRELESS_EXT abuse

This patch contains the following changes:
- add a CONFIG_WIRELESS_EXT select'ed by NET_RADIO for conditional
  code
- remove the now no longer required #ifdef CONFIG_NET_RADIO from some
  #include's

Based on a patch by Jean Tourrilhes <jt@hpl.hp.com>.

Subject: [PATCH] ieee80211: common wx auth code

This patch creates two functions ieee80211_wx_set_auth and
ieee80211_wx_get_auth that can be used by drivers for the wireless
extension handlers instead of writing their own, if the implementation
should be software only.

These patches enable using bcm43xx devices with WPA and this seems (as
far as I can tell) to be the only difference between the stock ieee80211
and softmac's ieee80211 left.

Subject: [PATCH] Add two management functions to ieee80211_rx.c

On my system, I get unhandled management functions corresponding
to IEEE80211_STYPE_REASSOC_REQ and IEEE80211_STYPE_ASSOC_REQ. The
attached patch adds the logic to pass these requests off to a user
stack. The patches to implement these requests in softmac have already
been sent to Johannes Berg.

It replaces returning WPA/RSN IEs as custom events with returning them
as IWEVGENIE events. I have tested that it returns proper information
with both Xsupplicant, and the latest development version of the Linux
wireless tools.

Subject: [PATCH] ieee80211_geo.c: remove frivolous BUG_ON's

I have come to consider BUG_ON generally harmful. The idea of an assert is
to prevent a program to execute past a point where its state is known
erroneous, thus preventing it from dealing more damage to the data
(or hiding the traces of malfunction). The problem is, in kernel this harm
has to be balanced against the harm of forced reboot.

The last straw was our softmac tree, where "iwlist eth1 scan" causes
a lockup. It is absolutely frivolus and provides no advantages a normal
assert has to provide. In fact, doing this impedes debugging.

Subject: [PATCH] bonding: suppress duplicate packets

	Originally submitted by Kenzo Iwami; his original description is:

The current bonding driver receives duplicate packets when broadcast/
multicast packets are sent by other devices or packets are flooded by the
switch. In this patch, new flags are added in priv_flags of net_device
structure to let the bonding driver discard duplicate packets in
dev.c:skb_bond().

	Modified by Jay Vosburgh to change a define name, update some
comments, rearrange the new skb_bond() for clarity, clear all bonding
priv_flags on slave release, and update the driver version.

 packets.

This patch fixes a problem in the ieee80211 probe response and beacon
reception code that would use the packet statistics for a network even
if they were received on a channel other than that which the network
exists on.

This causes a problem in overlapping channels where, for example, a
strong AP on channel 2 could have its beacons received on channels 1 and
3, but at much lower signal levels.  If scanning was done sequentially,
this means the beacon received on channel 3 would update the AP's signal
level as being much lower than it really is, which subsequently could
cause that AP to be passed over and an alternate AP selected.
