Linus Torvalds dbcc2ec60f Revert "mac80211: warn when receiving frames with unaligned data"
This reverts commit 81100eb80a for the
release, to avoid the unnecessary warning noise that is only really
relevant to wireless driver developers.

The warning will probably go right back in after I cut the release, but
at least we won't unnecessarily worry users.

Johannes Berg 81100eb80a mac80211: warn when receiving frames with unaligned data
This patch makes mac80211 warn (once) when the driver passes up a
frame in which the payload data is not aligned on a four-byte
boundary, with a long comment for people who run into the condition
and need to know what to do.

Johannes Berg 3333590e94 mac80211: fix header ops
When using recvfrom() on a SOCK_DGRAM packet socket, I noticed that the MAC
address passed back for wireless frames was always completely wrong. The
reason for this is that the header parse function assigned to our virtual
interfaces is a function parsing an 802.11 rather than 802.3 header. This
patch fixes it by keeping the default ethernet header operations assigned.

Zhu Yi a10605e599 mac80211: free ifsta->extra_ie and clear IEEE80211_STA_PRIVACY_INVOKED
I'm not sure if this is best choice, someone might have better
solutions. But this patch fixed the connection problem when switching
from a WPA enabled AP (using wpa_supplicant) to an open AP (using
iwconfig). The root cause is when we connect to a WPA enabled AP,
wpa_supplicant sets the ifsta->extra_ie thru SIOCSIWGENIE. But if we
stop wpa_supplicant and connect to an open AP with iwconfig, there is
no way to clear the extra_ie so that mac80211 keeps connecting with that.

Someone could argue wpa_supplicant should clear the extra_ie during
its shutdown. But mac80211 should also handle the unexpected shutdown
case (ie. killall -9 wpa_supplicant).

When an interface with promisc/allmulti bit is taken down,
the mac80211 state can become confused. This fixes it by

Johannes Berg b52f2198ac mac80211: fix ieee80211_set_multicast_list
I recently experienced unexplainable behaviour with the b43
driver when I had broken firmware uploaded. The cause may have
been that promisc mode was not correctly enabled or disabled
and this bug may have been the cause.

Note how the values are compared later in the function so
just doing the & will result in the wrong thing being
compared and the test being false almost always.

Make "decrypt failed" and "have no key" debugging messages compile
conditionally upon CONFIG_MAC80211_DEBUG.  They have been useful for
finding certain problems in the past, but in many cases they just
clutter a user's logs.

A typical example is an enviornment where multiple SSIDs are using a
single BSSID but with different protection schemes or different keys
for each SSID.  In such an environment these messages are just noise.
Let's just leave them for those interested enough to turn-on debugging.

happened to work for ia64, powerpc, sparc64 and x86 because they
happened to drag in that file via their <asm/dma-mapping.h>.

On most of the others this probably broke.

John W. Linville 67a4cce4a8 [PATCH] mac80211: make ieee802_11_parse_elems return void
Some APs send management frames with junk padding after the last IE.
We already account for a similar problem with some Apple Airport
devices, but at least one device is known to send more than a single
extra byte.  The device in question is the Draytek Vigor2900:

	http://www.draytek.com.au/products/Vigor2900.php

The junk in question looks like an IE that runs off the end of the
frame.  This cause us to return ParseFailed.  Since the frame in
question is an association response, this causes us to fail to associate
with this AP.

The return code from ieee802_11_parse_elems is superfluous.
All callers still check for the presence of the specific IEs that
interest them anyway.  So, remove the return code so the parse never
"fails".

John W. Linville 0654ff055c [PATCH] ieee80211_if_set_type: make check for master dev more explicit
Problem description by Daniel Drake <dsd@gentoo.org>:

"This sequence of events causes loss of connectivity:

<plug in>
<associate as normal in managed mode>
ifconfig eth7 down
iwconfig eth7 mode monitor
ifconfig eth7 up
ifconfig eth7 down
iwconfig eth7 mode managed
<associate as normal>

At this point you are associated but TX does not work. This is because
the eth7 hard_start_xmit is still ieee80211_monitor_start_xmit."

The problem is caused by ieee80211_if_set_type checking for a non-zero
hard_start_xmit pointer value in order to avoid changing that value for
master devices.  The fix is to make that check more explicitly linked to
master devices rather than simply checking if the value has been
previously set.

Johannes Berg 640845a563 [MAC80211]: use RX_FLAG_DECRYPTED for sw decrypted as well
This makes mac80211 set the RX_FLAG_DECRYPTED flag for frames
decrypted in software allowing us to handle some things more
uniformly.

Johannes Berg 1990af8d14 [MAC80211]: consolidate decryption more
Currently, we have three RX handlers doing the decryption.
This patch changes it to have only one handler doing
everything, thereby getting rid of many duplicate checks.
