This patch adds the authenc algorithm which constructs an AEAD algorithm
from an asynchronous block cipher and a hash. The construction is done
by concatenating the encrypted result from the cipher with the output

The authenc algorithm exists as a template with four parameters:
authenc(auth, authsize, enc, enckeylen).
The authentication algorithm, the authentication size (i.e., truncating
the output of the authentication algorithm), the encryption algorithm,
and the encryption key length. Both the size field and the key length
field are in bytes. For example, AES-128 with SHA1-HMAC would be
represented by
authenc(hmac(sha1), 12, cbc(aes), 16)
The key for the authenc algorithm is the concatenation of the keys for
the authentication algorithm with the encryption algorithm. For the
above example, if a key of length 36 bytes is given, then hmac(sha1)
would receive the first 20 bytes while the last 16 would be given to
cbc(aes).

The TX datalen must always be converted to a value rt73 and rt2500usb
understand. Both require to use a different size then skb->len.
First off this is required because the descriptor must be added,
but the second is because the value must be a multiple of either 2 or 4,
and it should not be a multiple of the USB packetmax

[PATCH] rt2x00: Fix rfkill handling
As reported by Modestas Vainius, enabling rkfill in 1 driver and
disabling it in a second could cause a NULL pointer exception when
the rfkill-disabled driver still sets the CONFIG_SUPPORT_HW_BUTTON flag.
Furthermore, rfkill expects the timeout as a value in milliseconds
instead of jiffies. Also increase the timeout to a second,
since this 250ms would be overkill.
Also the flag DEVICE_ENABLED_RADIO_HW is causing problems
for devices which do not support the hardware button
while rfkill is enabled in the driver.
To remidy this we should inverse the flag and its meaning,
rename the flag to DEVICE_DISABLED_RADIO_HW this means that
by default the radio is enabled by the hardware button (if present)
and can only be disabled explicitely.

[PATCH] rt2x00: Don't use changed_flags inside configure_packet_filter
We shouldn't use changed_flags when configuring the packet filter,
we work directly with the total_flags which is safe enough since
we already check if something has changed after we applied our
packet filtering flag rules.
Also make sure that when the packet filter is scheduled, the
rt2x00dev->interface.filter is cleared to make sure the drivers
will update the packet filter instead of failing at the check:
*total_flags == rt2x00dev->interface.filter

[PATCH] ipw2200: batch non-user-requested scan result notifications
ipw2200 makes extensive use of background scanning when unassociated or
down. Unfortunately, the firmware sends scan completed events many
times per second, which the driver pushes directly up to userspace.
This needlessly wakes up processes listening for wireless events many
times per second. Batch together scan completed events for
non-user-requested scans and send them up to userspace every 4 seconds.
Scan completed events resulting from an SIOCSIWSCAN call are pushed up
without delay.

[IPSEC]: Lock state when copying non-atomic fields to user-space
This patch adds locking so that when we're copying non-atomic fields such as
life-time or coaddr to user-space we don't get a partial result.
For af_key I've changed every instance of pfkey_xfrm_state2msg apart from
expiration notification to include the keys and life-times. This is in-line
with XFRM behaviour.
The actual cases affected are:
* pfkey_getspi: No change as we don't have any keys to copy.
* key_notify_sa:
+ ADD/UPD: This wouldn't work otherwise.
+ DEL: It can't hurt.

[XFRM] user: Move attribute copying code into copy_to_user_state_extra
Here's a good example of code duplication leading to code rot. The
notification patch did its own netlink message creation for xfrm states.
It duplicated code that was already in dump_one_state. Guess what, the
next time (and the time after) when someone updated dump_one_state the
notification path got zilch.
This patch moves that code from dump_one_state to copy_to_user_state_extra
and uses it in xfrm_notify_sa too. Unfortunately whoever updates this
still needs to update xfrm_sa_len since the notification path wants to
know the exact size for allocation.
At least I've added a comment saying so and if someone still forgest, we'll
have a WARN_ON telling us so.
I also changed the security size calculation to use xfrm_user_sec_ctx since
that's what we actually put into the skb. However it makes no practical
difference since it has the same size as xfrm_sec_ctx.

[IPSEC]: Move common code into xfrm_alloc_spi
This patch moves some common code that conceptually belongs to the xfrm core
from af_key/xfrm_user into xfrm_alloc_spi.
In particular, the spin lock on the state is now taken inside xfrm_alloc_spi.
Previously it also protected the construction of the response PF_KEY/XFRM
messages to user-space. This is inconsistent as other identical constructions
are not protected by the state lock. This is bad because they in fact should
be protected but only in certain spots (so as not to hold the lock for too
long which may cause packet drops).
The SPI byte order conversion has also been moved.
