Three major portions to this change:
1) Add IW_EV_COMPAT_LCP_LEN, IW_EV_COMPAT_POINT_OFF,
and IW_EV_COMPAT_POINT_LEN helper defines.
2) Delete iw_stream_check_add_*(), they are unused.
3) Add iw_request_info argument to iwe_stream_add_*(), and use it to
size the event and pointer lengths correctly depending upon whether
IW_REQUEST_FLAG_COMPAT is set or not.
4) The mechanical transformations to the drivers and wireless stack
bits to get the iw_request_info passed down into the routines
modified in #3. Also, explicit references to IW_EV_LCP_LEN are
replaced with iwe_stream_lcp_len(info).
With a lot of help and bug fixes from Masakazu Mokuno.

Next we can kill the hacks in fs/compat_ioctl.c and also
dispatch compat ioctls down into the driver and 80211 protocol
helper layers in order to handle iw_point objects embedded in
stream replies which need to be translated.

This defines the flags for setting the PMK to the driver and the
capability flag for this so that the user space program can figure out
whether the target driver wants to do 4-way hand shake by itself and
pass the PMK which is needed before 4-way handshake to the driver.

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
padding space for the scan_capa field.

After 13 years of use, it looks like my email address is finally going
to disappear. While this is likely to drop the amount of incoming spam
greatly ;-), it may also affect more appropriate messages, so let's
update my email address in various places. In addition, Host AP mailing
list is subscribers-only and linux-wireless can also be used for
discussing issues related to this driver which is now shown in
MAINTAINERS.

Johannes Berg discovered that kernel space was leaking to
userspace on 64 bit platform. He made a first patch to fix that. This
is an improved version of his patch.

This is version 21 of the Wireless Extensions. Changelog :
o finishes migrating the ESSID API (remove the +1)
o netdev->get_wireless_stats is no more
o long/short retry
This is a redacted version of a patch originally submitted by Jean
Tourrilhes. I removed most of the additions, in order to minimize
future support requirements for nl80211 (or other WE successor).

This is version 20 of the Wireless Extensions. This is the
completion of the RtNetlink work I started early 2004, it enables the
full Wireless Extension API over RtNetlink.
Few comments on the patch :
o totally driver transparent, no change in drivers needed.
o iwevent were already RtNetlink based since they were created
(around 2.5.7). This adds all the regular SET and GET requests over
RtNetlink, using the exact same mechanism and data format as iwevents.
o This is a Kconfig option, as currently most people have no
need for it. Surprisingly, patch is actually small and well
encapsulated.
o Tested on SMP, attention as been paid to make it 64 bits clean.
o Code do probably too many checks and could be further
optimised, but better safe than sorry.
o RtNetlink based version of the Wireless Tools available on
my web page for people inclined to try out this stuff.
I would also like to thank Alexey Kuznetsov for his helpful
suggestions to make this patch better.

Hi Jeff,
This is version 19 of the Wireless Extensions. It was supposed
to be the fallback of the WPA API changes, but people seem quite happy
about it (especially Jouni), so the patch is rather small.
The patch has been fully tested with 2.6.13 and various
wireless drivers, and is in its final version. Would you mind pushing
that into Linus's kernel so that the driver and the apps can take
advantage ot it ?
It includes :
o iwstat improvement (explicit dBm). This is the result of
long discussions with Dan Williams, the authors of
NetworkManager. Thanks to him for all the fruitful feedback.
o remove pointer from event stream. I was not totally sure if
this pointer was 32-64 bits clean, so I'd rather remove it and be at
peace with it.
o remove linux header from wireless.h. This has long been
requested by people writting user space apps, now it's done, and it
was not even painful.
o final deprecation of spy_offset. You did not like it, it's
now gone for good.
o Start deprecating dev->get_wireless_stats -> debloat netdev
o Add "check" version of event macros for ieee802.11
stack. Jiri Benc doesn't like the current macros, we aim to please ;-)
All those changes, except the last one, have been bit-roting on
my web pages for a while...
Patches for most kernel drivers will follow. Patches for the
Orinoco and the HostAP drivers have been sent to their respective
maintainers.
Have fun...
Jean

This is version 18 of the Wireless Extensions. The main change
is that it adds all the necessary APIs for WPA and WPA2 support. This
work was entirely done by Jouni Malinen, so let's thank him for both
his hard work and deep expertise on the subject ;-)
This APIs obviously doesn't do much by itself and works in
concert with driver support (Jouni already sent you the HostAP
changes) and userspace (Jouni is updating wpa_supplicant). This is
also orthogonal with the ongoing work on in-kernel IEEE support (but
potentially useful).
The patch is attached, tested with 2.6.11. Normally, I would
ask you to push that directly in the kernel (99% of the patch has been
on my web page for ages and it does not affect non-WPA stuff), but
Jouni convinced me that it should bake a few weeks in wireless-2.6
first, so that other driver maintainers can get up to speed with it.

From: Jean Tourrilhes <jt@bougret.hpl.hp.com>
This is the patch to migrate Wireless Extension from WE-16 to
WE-17 for kernel 2.6.X. I would like you to queue that patch and
submit it to Linus as soon as 2.6.8 is released (so it can be fully
tested during 2.6.9). If you want, I can resend that as soon as 2.6.8
is released.
The patch is basically unchanged compared to the version
posted to the netdev list and my web page one month ago, I just
re-diff to the latest kernel (2.6.8-rc2-bk12). The patch already
included feedback from various driver maintainers, and nobody else
complained, so I guess it's ready.
The patch for some drivers inside the kernel will follow
(airo.c, wavelan.c, wavelan_cs). Patch for various other drivers
(orinoco, hostap, prism54) have been sent already to their maintainers
(one month ago) and basically waiting for this patch.
Changelog :
* - Add flags to frequency -> auto/fixed
* - Document (struct iw_quality *)->updated, add new flags (INVALID)
* - Wireless Event capability in struct iw_range
* - Add support for relative TxPower (yick !)
* - Change the way we get to spy_data method for added safety and hostap
* - Remove spy #ifdef, they are always on -> cleaner code
* - Allow any size GET request if user specifies length > max
* - Start migrating get_wireless_stats to struct iw_handler_def
* Based on patch from Pavel Roskin <proski@gnu.org> :
* - Fix kernel data leak to user space in private handler handling
I also added on my page a version of Wireless Tools that use
RtNetlink instead of ioctls. This is not as clean as I would like, but
is fully functional (if you have WE-19). I know that you were
interested, so feel free to send feedback on that...

This patch for 2.5.68-bk11 will update Wireless Extension to
version 16 :
o increase bitrate and frequency number for 802.11g/802.11a
o enhanced iwspy support
o minor tweaks and cleanups
This patch is only for the core of WE. The patches for the
individual drivers have been sent to their respective maintainers.
Compared to the previous version I sent you a few weeks ago,
I've just updated to the latest kernel.

This reduces the number of "nuber" by four and fixes the spelling
of necessary in one of those files.
|
|
for the HostAP driver, with few cleanups and new unused
definitions. The most contention change is that this version now
requires user space to provide the buffer size when making a GET (to
check buffer overrun), which will break very old version of Wireless
Tools (v22 and earlier).

Quick summary : this patch build on the first part to offer
two important new features :
o Wireless Events
o Wireless Cell Scanning
Wireless Events are events generated by device, driver or the
wireless subsystem. It allows for example a device to notify user
space when it register to a new cell (roaming) or loose contact with
the current Access Points. Currently, the other defined events include
some configuration changes and packet drop due to excessive retries,
more may come in the future. All those events are useful for MobileIP,
V-Handoff and Ad-Hoc routing.
Wireless Cell Scanning is a generic API to allow device/drive
to report Wireless Cells discovered (including ESSID, frequency and
QoS). This is similar to what is available in WindowsXP (except that
it's compliant to Wireless Extensions).
This patch has been submitted for review on this list a couple
of time in January, has been on my web page since and used intensively
by other people. It was rediffed to 2.5.6. Driver patches have been
submitted to maintainers.
