bnx2x: Look inside vlan when determining checksum proto.
Currently the skb->protocol field is used to setup checksum
offloading on transmit for the correct protocol. However, if
vlan offloading is disabled or otherwise not used, the protocol
field will be ETH_P_8021Q, not the actual protocol. This will
cause the checksum to be not computed correctly, even though the
hardware is capable of looking inside vlan tags. Instead,
look inside the header if necessary to determine the correct
protocol type.
To some extent this fixes a regression from 2.6.36 because it
was previously not possible to disable vlan offloading and this
error case was not exposed.

vlan: Add function to retrieve EtherType from vlan packets.
Depending on how a packet is vlan tagged (i.e. hardware accelerated or
not), the encapsulated protocol is stored in different locations. This
provides a consistent method of accessing that protocol, which is needed
by drivers, security checks, etc.

virtio-net: init link state correctly
For device that supports VIRTIO_NET_F_STATUS, there's no need to
assume the link is up and we need to call nerif_carrier_off() before
querying device status, otherwise we may get wrong operstate after
diver was loaded because the link watch event was not fired as

For device that does not support VIRITO_NET_F_STATUS, we could not get

PHY reports PHY changes. I belive adjust_link hangs somewhere,
holding the PHY lock, because ucc_geth_stop disabled the

netfilter: NF_HOOK_COND has wrong conditional
The NF_HOOK_COND returns 0 when it shouldn't due to what I believe to be an
error in the code as the order of operations is not what was intended. C will
evalutate == before =. Which means ret is getting set to the bool result,
rather than the return value of the function call. The code says
if (ret = function() == 1)
when it meant to say:
if ((ret = function()) == 1)
Normally the compiler would warn, but it doesn't notice it because its
a actually complex conditional and so the wrong code is wrapped in an explict
set of () [exactly what the compiler wants you to do if this was intentional].
Fixing this means that errors when netfilter denies a packet get propagated
back up the stack rather than lost.

filter: make sure filters dont read uninitialized memory
There is a possibility malicious users can get limited information about
uninitialized stack mem array. Even if sk_run_filter() result is bound
to packet length (0 .. 65535), we could imagine this can be used by
hostile user.
Initializing mem[] array, like Dan Rosenberg suggested in his patch is
expensive since most filters dont even use this array.
Its hard to make the filter validation in sk_chk_filter(), because of
the jumps. This might be done later.
In this patch, I use a bitmap (a single long var) so that only filters
using mem[] loads/stores pay the price of added security checks.
For other filters, additional cost is a single instruction.

Bluetooth: Fix non-SSP auth request for HIGH security level sockets
When initiating dedicated bonding a L2CAP raw socket with HIGH security
level is used. The kernel is supposed to trigger the authentication
request in this case but this doesn't happen currently for non-SSP
(pre-2.1) devices. The reason is that the authentication request happens
in the remote extended features callback which never gets called for
non-SSP devices. This patch fixes the issue by requesting also
authentiation in the (normal) remote features callback in the case of
non-SSP devices.
This rule is applied only for HIGH security level which might at first
seem unintuitive since on the server socket side MEDIUM is already
enough for authentication. However, for the clients we really want to
prefer the server side to decide the authentication requrement in most
cases, and since most client sockets use MEDIUM it's better to be
avoided on the kernel side for these sockets. The important socket to
request it for is the dedicated bonding one and that socket uses HIGH
security level.
The patch is based on the initial investigation and patch proposal from

ath9k_hw: Fix AR9280 surprise removal during frequent idle on/off
Bit 22 of AR_WA should be set to fix the situation where chip reset
is asynchronous to clock of analog shift registers, such that when
reset is released, it could mess up the values of analog shift registers
and cause some hw issue on AR9280.
This bit is write only, but the driver does a read-modify-write
on AR_WA without setting bit 22 in ar9002_hw_configpcipowersave()
during radio disable. This causes surprise removal of hw. It can
never recover from this state and the hw will become usable only
after a power on/off cycle, and sometimes only during a cold reboot.
This issue can be triggered by doing frequent roaming with the
simple/test-roam script available from the wifi-test project [1]
when roaming between APs quickly. When roaming there is a is a high
possibility that the device being put into idle (radio disable) state
by mac80211 during AUTH->ASSOC. A device hardware reset would fail

mac80211: unset SDATA_STATE_OFFCHANNEL when cancelling a scan
For client STA interfaces, ieee80211_do_stop unsets the relevant
interface's SDATA_STATE_RUNNING state bit prior to cancelling an
interrupted scan. When ieee80211_offchannel_return is invoked as
part of cancelling the scan, it doesn't bother unsetting the
SDATA_STATE_OFFCHANNEL bit because it sees that the interface is
down. Normally this doesn't matter because when the client STA
interface is brought back up, it will probably issue a scan. But
in some cases (e.g., the user changes the interface type while it
is down), the SDATA_STATE_OFFCHANNEL bit will remain set. This
prevents the interface queues from being started. So we
cancel the scan before unsetting the SDATA_STATE_RUNNING bit.

RDS: Let rds_message_alloc_sgs() return NULL
Even with the previous fix, we still are reading the iovecs once
to determine SGs needed, and then again later on. Preallocating
space for sg lists as part of rds_message seemed like a good idea
but it might be better to not do this. While working to redo that
code, this patch attempts to protect against userspace rewriting
the rds_iovec array between the first and second accesses.
The consequences of this would be either a too-small or too-large

sgs, and fail gracefully.
