f1b50863aa [PATCH] wireless/ipw2200: support WE-18 WPA enc_capa
This patch allows ipw2100 driver to advertise the WPA-related encryption
options that it does really support.  It's necessary to work correctly
with NetworkManager and other programs that actually check driver & card
capabilities.

4be757dd4c [PATCH] wireless/airo: add IWENCODEEXT and IWAUTH support
This patch adds IWENCODEEXT and IWAUTH support to the airo driver for
WEP and unencrypted operation.  No WPA though.  It allows the driver to
operate more willingly with wpa_supplicant and NetworkManager.

0a7bcf261e [PATCH] ipw2200: stack reduction
Checking the stack usage of my kernel, showed that ipw2200 had a few bad
offenders. This is on i386 32-bit:

0x00002876 ipw_send_associate:                          544
0x000028ee ipw_send_associate:                          544
0x000027dc ipw_send_scan_request_ext:                   520
0x00002864 ipw_set_sensitivity:                         520
0x00005eac ipw_set_rsn_capa:                            520

The reason is the host_cmd structure is large (500 bytes). All other
functions currently using ipw_send_cmd() suffer from the same problem.
This patch introduces ipw_send_cmd_simple() for commands with no data
transfer, and ipw_send_cmd_pdu() for commands with a data payload and
makes the payload a pointer to the buffer passed in from the caller.

As an added bonus, the diffstat looks like this:

 ipw2200.c |  260 +++++++++++++++++++++-----------------------------------------
 ipw2200.h |    2
 2 files changed, 92 insertions(+), 170 deletions(-)

and it shrinks the module a lot as well:

Before:

   text    data     bss     dec     hex filename
  75177    2472      44   77693   12f7d drivers/net/wireless/ipw2200.ko

After:

   text    data     bss     dec     hex filename
  61363    2488      44   63895    f997 drivers/net/wireless/ipw2200.ko

So about a ~18% reduction in module size.

397ae121ee [PATCH] ipw2200: Scale firmware loading watchdog with the firmware size
I can't really help with why restarts happen, but the following patch
greatly increases the likelihood that a firmware reload will succeed
afterward on my thinkpad. It addresses two issues. First, sysfs module
loading and hotplug are asynchronous, and as such file operations on the
"loading" and "data" files are racy when you load 2 firmwares in quick
succession. Second, the timeout for DMAing the firmware needs to scale
with the size of the firmware being loaded. That is, the watchdog needs
to be on throughput, not on time alone.

I no longer get the firmware load errors, though this is at best a hacky
workaround for a racy interface. (Obviously, this does nothing to address
the fatal errors in firmware which cause reloads; it just causes the
initial loading and the reloads to work more often.)

b6e4da7234 [PATCH] ipw2100: Fix setting txpower failed problem
The ipw2100 driver misunderstood the parameter of txpower.
Tx Power off means turn off the radio, but the driver interpret it as
"can't set txpower". So when getting the txpower, it sets disabled=1 to
the iwconifg tool in managed mode. And the tool will display "Tx Power off"
when disabled=1.

Now, in managed mode, iwconfig will not show "TX Power" if the radio is not
switched off. It will only display "Tx Power off" only if the radio is killed.

things:

1) Implements SIOCSIWENCODEEXT, SIOCGIWENCODEEXT, SIOCSIWAUTH, and
SIOCGIWAUTH calls for unencrypted and WEP operation

2) Accepts zero-filled addresses for SIOCSIWAP, which are legal and
should turn off any previous forced WAP address

3) Sends association and de-association events to userspace at most of
the appropriate times

4) Fixes erroneous order of CIPHER_SUITE_WEP_* arguments in one location
which are actually unused anyway

33f0f88f1c [PATCH] TTY layer buffering revamp
The API and code have been through various bits of initial review by
serial driver people but they definitely need to live somewhere for a
while so the unconverted drivers can get knocked into shape, existing
drivers that have been updated can be better tuned and bugs whacked out.

This replaces the tty flip buffers with kmalloc objects in rings. In the
normal situation for an IRQ driven serial port at typical speeds the
behaviour is pretty much the same, two buffers end up allocated and the
kernel cycles between them as before.

When there are delays or at high speed we now behave far better as the
buffer pool can grow a bit rather than lose characters. This also means
that we can operate at higher speeds reliably.

For drivers that receive characters in blocks (DMA based, USB and
especially virtualisation) the layer allows a lot of driver specific
code that works around the tty layer with private secondary queues to be
removed. The IBM folks need this sort of layer, the smart serial port
people do, the virtualisers do (because a virtualised tty typically
operates at infinite speed rather than emulating 9600 baud).

Finally many drivers had invalid and unsafe attempts to avoid buffer
overflows by directly invoking tty methods extracted out of the innards
of work queue structs. These are no longer needed and all go away. That
fixes various random hangs with serial ports on overflow.

The other change in here is to optimise the receive_room path that is
used by some callers. It turns out that only one ldisc uses receive room
except asa constant and it updates it far far less than the value is
read. We thus make it a variable not a function call.

I expect the code to contain bugs due to the size alone but I'll be
watching and squashing them and feeding out new patches as it goes.

Because the buffers now dynamically expand you should only run out of
buffering when the kernel runs out of memory for real.  That means a lot of
the horrible hacks high performance drivers used to do just aren't needed any
more.

Description:

tty_insert_flip_char is an old API and continues to work as before, as does
tty_flip_buffer_push() [this is why many drivers dont need modification].  It
does now also return the number of chars inserted

There are also

tty_buffer_request_room(tty, len)

which asks for a buffer block of the length requested and returns the space
found.  This improves efficiency with hardware that knows how much to
transfer.

and tty_insert_flip_string_flags(tty, str, flags, len)

to insert a string of characters and flags

For a smart interface the usual code is

    len = tty_request_buffer_room(tty, amount_hardware_says);
    tty_insert_flip_string(tty, buffer_from_card, len);

More description!

At the moment tty buffers are attached directly to the tty.  This is causing a
lot of the problems related to tty layer locking, also problems at high speed
and also with bursty data (such as occurs in virtualised environments)

I'm working on ripping out the flip buffers and replacing them with a pool of
dynamically allocated buffers.  This allows both for old style "byte I/O"
devices and also helps virtualisation and smart devices where large blocks of
data suddenely materialise and need storing.

So far so good.  Lots of drivers reference tty->flip.*.  Several of them also
call directly and unsafely into function pointers it provides.  This will all
break.  Most drivers can use tty_insert_flip_char which can be kept as an API
but others need more.

At the moment I've added the following interfaces, if people think more will
be needed now is a good time to say

 int tty_buffer_request_room(tty, size)

Try and ensure at least size bytes are available, returns actual room (may be
zero).  At the moment it just uses the flipbuf space but that will change.
Repeated calls without characters being added are not cumulative.  (ie if you
call it with 1, 1, 1, and then 4 you'll have four characters of space.  The
other functions will also try and grow buffers in future but this will be a
more efficient way when you know block sizes.

 int tty_insert_flip_char(tty, ch, flag)

As before insert a character if there is room.  Now returns 1 for success, 0
for failure.

 int tty_insert_flip_string(tty, str, len)

Insert a block of non error characters.  Returns the number inserted.

 int tty_prepare_flip_string(tty, strptr, len)

Adjust the buffer to allow len characters to be added.  Returns a buffer
pointer in strptr and the length available.  This allows for hardware that
needs to use functions like insl or mencpy_fromio.

f8cfa618dc [PATCH] pcmcia: unify attach, EVENT_CARD_INSERTION handlers into one probe callback
Unify the EVENT_CARD_INSERTION and "attach" callbacks to one unified
probe() callback. As all in-kernel drivers are changed to this new
callback, there will be no temporary backwards-compatibility. Inside a
probe() function, each driver _must_ set struct pcmcia_device
*p_dev->instance and instance->handle correctly.

With these patches, the basic driver interface for 16-bit PCMCIA drivers
now has the classic four callbacks known also from other buses:

        int (*probe)            (struct pcmcia_device *dev);
        void (*remove)          (struct pcmcia_device *dev);

        int (*suspend)          (struct pcmcia_device *dev);
