smc911x irq sense request and MPR2 board support
Hi,
this are the changes to the smc911x driver, which were necessary
to get it running on the Magic Panel R2 (smsc9115).
It is a SH3-DSP based board. The other patches are available on
the linuxsh-dev mailinglist.
http://marc.info/?l=linuxsh-dev&r=1&b=200708&w=2
It was necessary to set the irq sense to low level.
Therefor the SMC_IRQ_SENSE define was added.
How are the chances for inclusion in 2.6.24?

PHYLIB: fix an interrupt loop potential when halting
Ensure the PHY_HALTED state is not entered with the IRQ asserted as it
could lead to an interrupt loop.
There is a small window in phy_stop(), where the state of the PHY machine
indicates it has been halted, but its interrupt output might still be
unmasked. If an interrupt goes active right at this moment it will loop as
the phy_interrupt() handler exits immediately with IRQ_NONE if the halted
state is seen. It is unsafe to extend the phydev spinlock to cover
phy_interrupt(). It is safe to swap the order of the actions though as all
the competing places to unmask the interrupt output of the PHY, which are
phy_change() and phy_timer() are already covered with the lock as is the
sequence in question.

Keep track of disable_irq_nosync() invocations and call enable_irq() the
right number of times if work has been cancelled that would include them.
Now that the call to flush_work_keventd() (problematic because of
rtnl_mutex being held) has been replaced by cancel_work_sync() another
issue has arisen and been left unresolved. As the MDIO bus cannot be
accessed from the interrupt context the PHY interrupt handler uses
disable_irq_nosync() to prevent from looping and schedules some work to be
done as a softirq, which, apart from handling the state change of the
originating PHY, is responsible for reenabling the interrupt. Now if the
interrupt line is shared by another device and a call to the softirq
handler has been cancelled, that call to enable_irq() never happens and the
other device cannot use its interrupt anymore as its stuck disabled.
I decided to use a counter rather than a flag because there may be more
than one call to phy_change() cancelled in the queue -- a real one and a
fake one triggered by free_irq() if DEBUG_SHIRQ is used, if nothing else.
Therefore because of its nesting property enable_irq() has to be called the
right number of times to match the number disable_irq_nosync() was called
and restore the original state. This DEBUG_SHIRQ feature is also the
reason why free_irq() has to be called before cancel_work_sync().
While at it I updated the comment about phy_stop_interrupts() being called
from `keventd' -- this is no longer relevant as the use of
cancel_work_sync() makes such an approach unnecessary. OTOH a similar
comment referring to flush_scheduled_work() in phy_stop() still applies as
using cancel_work_sync() there would be dangerous.
Checked with checkpatch.pl and at the run time (with and without
DEBUG_SHIRQ).

Use spin_lock_bh()/spin_unlock_bh() for the phydev lock throughout as it
is used in phy_timer() that is called as a softirq and all the other
operations may happen in the user context.
There has been a change recently that did such a conversion for some of the
operations on the lock, but some have been left intact. Many of them,
perhaps all, may be called in the user context and I was able to trigger
recursive spinlock acquisition indeed, so I think for the sake of long-term
maintenance it is best to convert them all, even if unnecessarily for one
or two -- better safe than sorry.
Perhaps one in phy_timer() could actually be skipped as only called as a
softirq -- I can send an update if that sounds like a good idea.

[PATCH] mac80211: consolidate encryption
Currently we run through all crypto handlers for each transmitted
frame although we already know which one will be used. This
changes the code to invoke only the needed handler. It also moves
the wep code into wep.c.

[PATCH] mac80211: consolidate decryption
Currently, we run through all three crypto algorithms for each
received frame even though we have previously determined which
key we have and as such already know which algorithm will be
used. Change it to invoke only the needed function. Also move
the WEP decrypt handler to wep.c so that fewer functions need
to be non-static.

[PATCH] mac80211: pass frames to monitor interfaces early
This makes mac80211 pass all frames to monitor interfaces early
before all receive processing with the benefit that only a single
copy needs to be made, all monitors can receive clones of the skb
and if the frame will be discarded we don't even need to make a
single copy.

[PATCH] mac80211: fix interface initialisation and deinitialisation
When an interface is registered it is still uninitialised so
ieee80211_if_reinit() can't be called on it (it will oops.)
Hence, we need to move the uninit method assignment.
Also, this patch fixes the bug that the master device is never
initialised nor deinitialised at all. Oddly, the deinit code
had an if statement to not run some code when running for the
master interface (which never happened), but that if statement
is also wrong. Fix that too.
Now that the uninit code is run for the master device, another
bug surfaced: it tries to remove all dependent interfaces and
that oopses or BUGs at some point, either because it unregisters
already unregistered interfaces (missing list_del bug) or due
to trying to iterate a list that has had other things removed.
Fix this too by handling the master interface specially.

[PKT_SCHED]: Add stateless NAT
Stateless NAT is useful in controlled environments where restrictions are
placed on through traffic such that we don't need connection tracking to
correctly NAT protocol-specific data.
In particular, this is of interest when the number of flows or the number
of addresses being NATed is large, or if connection tracking information
has to be replicated and where it is not practical to do so.
Previously we had stateless NAT functionality which was integrated into
the IPv4 routing subsystem. This was a great solution as long as the NAT
worked on a subnet to subnet basis such that the number of NAT rules was
relatively small. The reason is that for SNAT the routing based system
had to perform a linear scan through the rules.
If the number of rules is large then major renovations would have take
place in the routing subsystem to make this practical.
For the time being, the least intrusive way of achieving this is to use
the u32 classifier written by Alexey Kuznetsov along with the actions
infrastructure implemented by Jamal Hadi Salim.
The following patch is an attempt at this problem by creating a new nat
action that can be invoked from u32 hash tables which would allow large
number of stateless NAT rules that can be used/updated in constant time.
The actual NAT code is mostly based on the previous stateless NAT code
written by Alexey. In future we might be able to utilise the protocol
NAT code from netfilter to improve support for other protocols.
