Some APs refuse association if the supported rates contained in the
association request do not match its own supported rates. This patch
introduces a new function which builds the intersection between the AP's
supported rates and the client's supported rates to work around such
problems. The same approach is already used in ipw2200 for example.

When, for some reason, the rt2x00pci module fails to allocate DMA memory for
the queues, it tries to undo the complete initialization of the PCI device,
including freeing of the irq. This results in the following error in dmesg, as
the irq hadn't been requested yet:
[ 78.123456] Trying to free already-free IRQ 17
Fix this by implementing proper error handling code, instead of just using the
full uninitialization function.

During initialization the initialize() callback function
in rt2x00pci and rt2x00usb will cleanup the mess they made.
rt2x00lib shouldn't call uninitialize because the callback function already
cleaned up _and_ the DEVICE_INITIALIZED isn't set which causes the
rt2x00lib_uninitialize() to halt directly anyway. All that is required
to be cleaned up by rt2x00lib is the queue, and that can be done by
calling rt2x00queue_uninitialize() directly.

rt2x00pci allocates DMA for descriptor and data,
rt61pci doesn't use this for the beacon, but it can
use the descriptor part as temporary buffer instead
of using pskb_expand_head().
Using this temporary buffer is obviously much better
then reallocating the skb buffer...
At the same time we can set the data length for the
beacon queue at 0, to make sure no DMA is allocated for
data (but just for the descriptor).

A file in the net/mac80211 directory uses "int" for flags. This can cause
hard to find bugs on some architectures. This patch converts the flags to use
"long" instead.
This bug was discovered by doing an allyesconfig make on the -rt kernel where
checks are done to ensure all flags are of size sizeof(long).

If session is NULL, it is not possible to access its name field. So I
have split apart the printing of the error message to drop the
printing of the name field in this case.
The macro PRINTK actually only evaluates its arguments starting with
the third one if the bitwise conjunction of the first two is non-zero.
Normally, this conjunction would only be non-zero if debugging mode
were turned on, but when session is NULL, the first argument in both
the old and new code is -1, and thus the bitwise conjunction is true.
Perhaps a different strategy is desired, such as using tunnel->debug,
which session->debug is initialized to, but tunnel can also be NULL,
so this does not completely solve the problem.
This problem was found using the following semantic match

When a net namespace is destroyed, some devices (those, not killed
on ns stop explicitly) are moved back to init_net.
The problem, is that this net_ns change has one point of failure -
the __dev_alloc_name() may be called if a name collision occurs (and
this is easy to trigger). This allocator performs a likely-to-fail
GFP_ATOMIC allocation to find a suitable number. Other possible
conditions that may cause error (for device being ns local or not
registered) are always false in this case.
So, when this call fails, the device is unregistered. But this is
*not* the right thing to do, since after this the device may be
released (and kfree-ed) improperly. E. g. bridges require more
actions (sysfs update, timer disarming, etc.), some other devices
want to remove their private areas from lists, etc.
I. e. arbitrary use-after-free cases may occur.
The proposed fix is the following: since the only reason for the
dev_change_net_namespace to fail is the name generation, we may
give it a unique fall-back name w/o %d-s in it - the dev<ifindex>
one, since ifindexes are still unique.
So make this change, raise the failure-case printk loglevel to
EMERG and replace the unregister_netdevice call with BUG().

request
Some Inovaphone PBXs exhibit very stange behaviour: when dialing for
example "123", the device sends INVITE requests for "1", "12" and
"123" back to back. The first requests will elicit error responses
from the receiver, causing the SIP helper to flush the RTP
expectations even though we might still see a positive response.
Note the sequence number of the last INVITE request that contained a
media description and only flush the expectations when receiving a
negative response for that sequence number.

As noticed by Ben Greear, macvlan crashes the kernel when unloading the
module. The reason is that it tries to clean up the macvlan_port pointer
on the macvlan device itself instead of the underlying device. A non-NULL
pointer is taken as indication that the macvlan_handle_frame_hook is
valid, when receiving the next packet on the underlying device it tries
to call the NULL hook and crashes.
Clean up the macvlan_port on the correct device to fix this.

Note: there's actually another bug in FRTO's SACK variant, which
is the causing failure in NewReno case because of the error
that's fixed here. I'll fix the SACK case separately (it's
a separate bug really, though related, but in order to fix that
I need to audit tp->snd_nxt usage a bit).
There were two places where SACK variant of FRTO is getting
incorrectly used even if SACK wasn't negotiated by the TCP flow.
This leads to incorrect setting of frto_highmark with NewReno
if a previous recovery was interrupted by another RTO.
An eventual fallback to conventional recovery then incorrectly
considers one or couple of segments as forward transmissions
though they weren't, which then are not LOST marked during
fallback making them "non-retransmittable" until the next RTO.
In a bad case, those segments are really lost and are the only
one left in the window. Thus TCP needs another RTO to continue.
The next FRTO, however, could again repeat the same events
making the progress of the TCP flow extremely slow.
In order for these events to occur at all, FRTO must occur
again in FRTOs step 3 while the key segments must be lost as
well, which is not too likely in practice. It seems to most
frequently with some small devices such as network printers
that *seem* to accept TCP segments only in-order. In cases
were key segments weren't lost, things get automatically
resolved because those wrongly marked segments don't need to be
retransmitted in order to continue.
I found a reproducer after digging up relevant reports (few
reports in total, none at netdev or lkml I know of), some
cases seemed to indicate middlebox issues which seems now
to be a false assumption some people had made. Bugzilla
#10063 _might_ be related. Damon L. Chesser <damon@damtek.com>
had a reproducable case and was kind enough to tcpdump it
for me. With the tcpdump log it was quite trivial to figure
out.

Taken from http://bugzilla.kernel.org/show_bug.cgi?id=10577
I was unable to access a computer containing an Intel EtherExpress 16 network
card using IPv6.
I traced this to failure of neighbour discovery. When I used an "ip -6 neigh
add" command, on the computer attempting access, to insert a binding between
the IPv6 address of the computer with the Intel EtherExpress 16 network card
and the card's ethernet address, I was able to access that computer using
IPv6.
Neighbour discovery requires working multicast. The driver sources file
eexpress.c contains an approximately 30 line function eexp_setup_filter used
when loading multicast addresses.
I found 3 problems in this function
1) It wrote the number of multicast addresses to the card instead of the
number of bytes in the multicast addresses.
2) When loading multiple multicast addresses it loaded the first one
provided multiple times instead of loading each one once.
3) The setting of pointer 'data' from 'dmi->dmi_addr' occured before the
test for the error situation of 'dmi' being NULL.
Correcting these problems allows the computer with the Intel EtherExpress 16
network card to found by IPv6 neighbour discovery.
p.s. There is some information on the Intel EtherExpress 16 at
http://www.intel.com/support/etherexpress/vintage/sb/cs-013500.htm
