These bits are shared already between ipw2x00 and hostap, and could
probably be shared both more cleanly and with other drivers. This
commit simply relocates the code to lib80211 and adjusts the drivers
appropriately.

'iwconfig eth1 channel 6' would trigger association to _something_,
which is wrong. Changing the channel should (and does) trigger reassociation,

When another scan is in progress, a direct scan gets dropped on the
floor. However, that direct scan is usually the scan that's really
needed by userspace, and gets stomped on by all the broadcast scans the
ipw2200 driver issues internally. Make sure the direct scan happens
eventually, and as a bonus ensure that the passive scan worker is
cleaned up when appropriate.
The change of request_passive_scan form a struct work to struct
delayed_work is only to make the set_wx_scan() code a bit simpler, it's
still only used with a delay of 0 to match previous behavior.

If there are no networks on the free list, expire the oldest one when
creating a new adhoc network. Because ipw2200 and the ieee80211 stack
don't actually cull old networks and place them back on the free list
unless they are needed for new probe responses, over time the free list
would become empty and creating an adhoc network would fail due to the !

If print_mac() is used inside of a pr_debug() the compiler
can't see that the call is redundant so still performs it
even of pr_debug() ends up being a nop.
So don't use print_mac() in such cases in hot code paths,
use MAC_FMT et al. instead.
As noted by Joe Perches, pr_debug() could be modified to
handle this better, but that is a change to an interface
used by the entire kernel and thus needs to be validated
carefully. This here is thus the less risky fix for

Introduce scan capabilities to WEXT so that userspace can do intelligent
things with scan behavior such as handling hidden SSIDs more gracefully.
If the driver reports a specific scan capability, the driver must
respect the options specified in the iw_scan_req structure when handling
the SIOCSIWSCAN call, unless it's mode or state does not allow it to do
so, in which case it must return an error.
This version switches to Dave Kilroy's suggestion of claiming unused

ipw2200 makes extensive use of background scanning when unassociated or
down. Unfortunately, the firmware sends scan completed events many
times per second, which the driver pushes directly up to userspace.
This needlessly wakes up processes listening for wireless events many
times per second. Batch together scan completed events for
non-user-requested scans and send them up to userspace every 4 seconds.
Scan completed events resulting from an SIOCSIWSCAN call are pushed up
without delay.

The ipw2200 BSS firmware passes on the TSF information within ipw_rx_frame,
but monitor firmware doesn't. I add back the IEEE80211_RADIOTAP_TSFT flags
so that we can get the MAC timestamp if we use the rtap interface. We will
see the MAC timestamp equals to zero if we capture the packets with a
monitor mode interface. But this is the expected behaviour.

Maintain a per-CPU global "struct pt_regs *" variable which can be used instead
of passing regs around manually through all ~1800 interrupt handlers in the
Linux kernel.
The regs pointer is used in few places, but it potentially costs both stack
space and code to pass it around. On the FRV arch, removing the regs parameter
from all the genirq function results in a 20% speed up of the IRQ exit path
(ie: from leaving timer_interrupt() to leaving do_IRQ()).
Where appropriate, an arch may override the generic storage facility and do
something different with the variable. On FRV, for instance, the address is
maintained in GR28 at all times inside the kernel as part of general exception
handling.
Having looked over the code, it appears that the parameter may be handed down
through up to twenty or so layers of functions. Consider a USB character
device attached to a USB hub, attached to a USB controller that posts its
interrupts through a cascaded auxiliary interrupt controller. A character
device driver may want to pass regs to the sysrq handler through the input
layer which adds another few layers of parameter passing.
I've build this code with allyesconfig for x86_64 and i386. I've runtested the
main part of the code on FRV and i386, though I can't test most of the drivers.
I've also done partial conversion for powerpc and MIPS - these at least compile
with minimal configurations.
This will affect all archs. Mostly the changes should be relatively easy.
Take do_IRQ(), store the regs pointer at the beginning, saving the old one:
struct pt_regs *old_regs = set_irq_regs(regs);
And put the old one back at the end:
set_irq_regs(old_regs);
Don't pass regs through to generic_handle_irq() or __do_IRQ().
In timer_interrupt(), this sort of change will be necessary:
- update_process_times(user_mode(regs));
- profile_tick(CPU_PROFILING, regs);
+ update_process_times(user_mode(get_irq_regs()));
+ profile_tick(CPU_PROFILING);
I'd like to move update_process_times()'s use of get_irq_regs() into itself,
except that i386, alone of the archs, uses something other than user_mode().
Some notes on the interrupt handling in the drivers:
(*) input_dev() is now gone entirely. The regs pointer is no longer stored in
the input_dev struct.
(*) finish_unlinks() in drivers/usb/host/ohci-q.c needs checking. It does
something different depending on whether it's been supplied with a regs
pointer or not.
(*) Various IRQ handler function pointers have been moved to type
irq_handler_t.

This patch enables the ipw2200 driver to support passive scanning as

active scan request. Additionally, I added a new function called
ipw_request_passive_scan that is similiar to the ipw_request_scan
function to perform passive scans. Last but not least, I added a field
(in fact it is a work_struct struct) called request_passive_scan to

Note, this patch treats

The SIOCGIWFREQ ioctl fills the request structure's freq field by setting
the exponent to 0 and the mantissa to the current channel number. The
iwconfig tool works around this behaviour by looking up the frequency
from the channel table if a frequency below 1kHz is returned, other tools
(e.g. kwlaninfo) don't. According to the comment in the iwconfig source
the driver is supposed to return the frequency, not the channel number.

Well, this is not 100% if when the card fires two consecutive
interrupts. Though unlikely, it's better to protect early than seeing
some "weird" bugs one day. I proposed attached patch. If you can help to

With this patch, a new promiscuous mode is enabled. If the module is loaded
with the rtap_iface=1 module parameter, two interfaces will be created
(instead of just one).
The second interface is prefixed 'rtap' and provides received 802.11 frames
on the current channel to user space in a radiotap header format.
Example usage:
% modprobe ipw2200 rtap_iface=1
% iwconfig eth1 essid MyNetwork
% dhcpcd eth1
% tcpdump -i rtap0
If you do not specify 'rtap_iface=1' then the rtap interface will
not be created and you will need to turn it on via:
% echo 1 > /sys/bus/pci/drivers/ipw2200/*/rtap_iface
You can filter out what type of information is passed to user space via
the rtap_filter sysfs entry. Currently you can tell the driver to
transmit just the headers (which will provide the RADIOTAP and IEEE
802.11 header but not the payload), to filter based on frame control
type (Management, Control, or Data), and whether to report transmitted
frames, received frames, or both.
The transmit frame reporting is based on a patch by Stefan Rompf.
Filters can be get and set via a sysfs interface. For example, set the
filter to only send headers (0x7), don't report Tx'd frames (0x10), and
don't report data frames (0x100):
% echo 0x117 > /sys/bus/pci/drivers/ipw2200/*/rtap_filter
All your packets are belong to us:
% tethereal -n -i rtap0

This patch modifies the driver to support the ipw2200-fw-3.0 image format.
The 3.0 fw image does not add any new capabilities, but as a result of
image format changes, it should fix two problems experienced by users:
1) Race conditions with the request_firmware interface and udev/hotplug
are improved as only a single request_firmware call is now required to
load the firmware and microcode (vs. 3 separate calls previously)
2) The monitor mode firmware (sniffer) is now packaged with the correct
boot image so it can now function without frequent restarts.
Note: Once you apply this patch, you will also need to upgrade your
firmware image to the 3.0 version available from:

Set a meaningful silence threshold value (replacing our previous "0"
default), which gets rid of the gratuitous "Link deterioration"
notifications that we've been receiving from firmware. This
notification feature tells the driver information to help it determine
when to pre-emptively restart the firmware/ucode in anticipation of
firmware errors! But since setting this new threshold, I haven't seen
any such notifications. At least it keeps the logs a little less busy.

The patch roll back the change we made to support for the ability to
start/stop independent Tx queues within a single net device in order to
support 802.11e QoS. We need to be able to indicate to the upper layers
that packets of a given priority can not be sent any more without halting
transmission of all packets, and without rescheduling high priority packets
down to the next priority level.
So we return NETDEV_TX_BUSY in this case and rely on the stack would
take care of rescheduling... which it apparently does immediately and
consumes the CPU. This caused the ksoftirqd kernel thread consuming almost
all the CPU...
To put the code back to the way it was before we made these changes we
put the call netif_queue_stop back in ipw_tx_skb. This effectively
disables multiple priority based transmit queues for 802.11e, but given
that its broken anyway...

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.

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.)

This fixes a slab corruption issue in the ipw2200 driver: it essentially
multiplied the error log number _twice_ by the size of the error element
entry (once explicitly in the code, and once implicitly as part of the
regular pointer arithmetic).

The function ipw_request_direct_scan() should bail out when the device
is down. This fixes a lockup caused by wpa_supplicant triggering
ipw_request_direct_scan() while the driver was in a middle of a reset
due to firmware errors.
Thanks to Zilvinas Valinskas for reporting the bug and helping me
debug it.

This patch removes almost all inclusions of linux/version.h. The 3
#defines are unused in most of the touched files.
A few drivers use the simple KERNEL_VERSION(a,b,c) macro, which is
unfortunatly in linux/version.h.
There are also lots of #ifdef for long obsolete kernels, this was not
touched. In a few places, the linux/version.h include was move to where
the LINUX_VERSION_CODE was used.

The problem is caused by the patch in bug455 -- Channel change flood
generates fatal error.
The patch set the DISASSOCIATING status bit after sending the command.
The process was scheduled out when waiting for the command to be sent to
the card. The disassociated notification clears the DISASSOCIATING bit
in the tasklet before the process set the bit.
Move the bit setting code before sending the command now.

Because of the frequent channel change, it is possible that when we are
try to associate with channel 1 (authenticated but not associated).
Another channel change comes at this time, then the driver will issue
disassociate command to the firmware which will cause the fatal error.
It seems that the association/disassociation procedure should not be
interrupted.
The patch attached adds test on STATUS_ASSOCIATING | STATUS_DISASSOCIATING
in ipw_send_cmd(), when ensures that commands will not be sent to firmware
when we are in these two status.

We send SYSTEM_CONFIG command after the TGI_KEY command if hardware
encryption is enabled. It sometimes causes a firmware stall (firmware
doesn't respond to any request) and finally bungs up the Tx send queue.
The solution is to send SYSTEM_CONFIG command in the post association
stage from a workqueue.
