Recently I posted a patch to add some informational items to
/proc/net/sctp/assocs. All the information is correct, but because
of how the seqfile show operation is laid out, some of the formatting
is backwards. This patch corrects that formatting, so that the new

Allow the use of SACK and window scaling when syncookies are used
and the client supports tcp timestamps. Options are encoded into
the timestamp sent in the syn-ack and restored from the timestamp
echo when the ack is received.
Based on earlier work by Glenn Griffin.
This patch avoids increasing the size of structs by encoding TCP
options into the least significant bits of the timestamp and
by not using any 'timestamp offset'.
The downside is that the timestamp sent in the packet after the synack
will increase by several seconds.

[SKFILTER]: Add SKF_ADF_NLATTR instruction
SKF_ADF_NLATTR searches for a netlink attribute, which avoids manually
parsing and walking attributes. It takes the offset at which to start
searching in the 'A' register and the attribute type in the 'X' register
and returns the offset in the 'A' register. When the attribute is not
found it returns zero.
A top-level attribute can be located using a filter like this
(example for nfnetlink, using struct nfgenmsg):
...
{
/* A = offset of first attribute */
.code = BPF_LD | BPF_IMM,
.k = sizeof(struct nlmsghdr) + sizeof(struct nfgenmsg)
},
{
/* X = CTA_PROTOINFO */
.code = BPF_LDX | BPF_IMM,
.k = CTA_PROTOINFO,
},
{
/* A = netlink attribute offset */
.code = BPF_LD | BPF_B | BPF_ABS,
.k = SKF_AD_OFF + SKF_AD_NLATTR
},
{
/* Exit if not found */
.code = BPF_JMP | BPF_JEQ | BPF_K,
.k = 0,
.jt = <error>
},
...
A nested attribute below the CTA_PROTOINFO attribute would then
be parsed like this:
...
{
/* A += sizeof(struct nlattr) */
.code = BPF_ALU | BPF_ADD | BPF_K,
.k = sizeof(struct nlattr),
},
{
/* X = CTA_PROTOINFO_TCP */
.code = BPF_LDX | BPF_IMM,
.k = CTA_PROTOINFO_TCP,
},
{
/* A = netlink attribute offset */
.code = BPF_LD | BPF_B | BPF_ABS,
.k = SKF_AD_OFF + SKF_AD_NLATTR
},
...
The data of an attribute can be loaded into 'A' like this:
...
{
/* X = A (attribute offset) */
.code = BPF_MISC | BPF_TAX,
},
{
/* A = skb->data[X + k] */
.code = BPF_LD | BPF_B | BPF_IND,
.k = sizeof(struct nlattr),

mac80211: fix key vs. sta locking problems
Up to now, key manipulation is supposed to run under RTNL to
avoid concurrent manipulations and also allow the set_key()
hardware callback to sleep. This is not feasible because STA
structs are rcu-protected and thus a lot of operations there
cannot take the RTNL. Also, key references are rcu-protected
so we cannot do things atomically.
This patch changes key locking completely:
* key operations are now atomic
* hardware crypto offload is enabled and disabled from
a workqueue, due to that key freeing is also delayed
* debugfs code is also run from a workqueue
* keys reference STAs (and vice versa!) so during STA
unlink the STAs key reference is removed but not the
keys STA reference, to avoid races key todo work is
run before STA destruction.
* fewer STA operations now need the RTNL which was
required due to key operations
This fixes the locking problems lockdep pointed out and also
makes things more light-weight because the rtnl isn't required
as much.
Note that the key todo lock/key mutex are global locks, this
is not required, of course, they could be per-hardware instead.

mac80211: fix possible sta-debugfs work lockup
Because we queue the sta-debugfs-adding work on our mac80211
workqueue (which needs to be flushed under RTNL) and that work
needs the RTNL, it can currently deadlock, thanks to Reinette
Chatre for pointing out the lockdep warning about this.
This patch fixes it by moving this work to the common kernel
workqueue (using schedule_work) and canceling it as appropriate.
It also fixes a related problem: When a STA is pinned by the
debugfs adding work and sta_info_flush() runs concurrently
it is not guaranteed that all STAs are removed from the driver
before the corresponding interface is removed which may lead
to bugs.

wavelan_cs: stop inlining largish static functions
Hi John,
Can you please take a look at this patch?
drivers/net/wireless/wavelan_cs.c has unusually large number
of static inline functions - 27.
I looked through them and 20 of them do not seem to warrant inlining.
Some are really big; others call mdelay(1) or busy-wait for a bit
to be set in a hardware register - it's pointless
to optimize such functions for speed.
This patch removes "inline" from these static function
(regardless of number of callsites - gcc nowadays auto-inlines
statics with one callsite).

b43: Add PIO support for PCMCIA devices
This adds PIO support back (D'oh!) for PCMCIA devices.
This is a complete rewrite of the old PIO code. It does actually work
and we get reasonable performance out of it on a modern machine.
On a PowerBook G4 I get a few MBit for TX and a few more for RX.
So it doesn't work as well as DMA (of course), but it's a _lot_ faster
than the old PIO code (only got a few kBit with that).
The limiting factor is the host CPU speed. So it will generate 100%
CPU usage when the network interface is heavily loaded. A voluntary preemption
point in the RX path makes sure Desktop Latency isn't hurt.
PIO is needed for 16bit PCMCIA devices, as we really don't want to poke with
the braindead DMA mechanisms on PCMCIA sockets. Additionally, not all
PCMCIA sockets do actually support DMA in 16bit mode (mine doesn't).

That patch breaks mesh config comparison between beacons/probe reponses, so
every beacon from a mesh network would be added as a new bss. Since the
comparison has to be performed for every received beacon I believe it is best to
save the mesh config in a format easy to compare, rather than do a bunch of
