From: Luis R. Rodriguez on 17 May 2010 21:30
2.6.34 was released today and now we get a respective compat-wireless
stable [1] tarball based on it [2]. This gives us the 2.6.34 802.11
subsystem, bluetooth subsystem and new 802.11/bluetooth drivers
compilable and installable on older kernels. Please report any issues
ASAP. For details on changes you can refer to the
ChangeLog-2.6.34-wireless [3].

Worth mentioning for this release is I've updated the version tagging
for compat-wireless to allow distributions/users/developers to keep
better track of what exact revision is being used. This was based on
Pavel Roskin's suggestion to use read-only module parameters which are
kept even if you build this tarball into your kernel somehow. Here is
an example of the new files and example output based on this specific
new tarball release:

$ sudo grep '' /sys/module/compat/parameters/compat_*
/sys/module/compat/parameters/compat_base_tree:linux-2.6-allstable.git
/sys/module/compat/parameters/compat_base_tree_version:v2.6.34
/sys/module/compat/parameters/compat_version:compat-wireless-v2.6.34-6-g0ad438e

Upon loading the compat module you would also see this output:

Compat-wireless backport release: compat-wireless-v2.6.34-6-g0ad438e
Backport based on linux-2.6-allstable.git v2.6.34

Since git describe is being used to describe both the base tree and
the compat-wireless release you will be able to tell how many patches
on top of the base tree have been applied. This should account for any
deltas you have created and reflect that (hope is the delta is always
0 with respect to upstream). In the above example output there are 6
patches on top of the "compat-wireless-v2.6.34" tag I created for the
first release, I then found some bugs due to the new version scheme
changes and fixed some of them, so I have applied 6 patches on top of
the original release.

I should note there are a few modules which *do not* make use of the
compat module but do make use of a lot of the defines at build time,
an example of such a module is rndis_wlan so you'd have to load the
compat module manually to get the above info or run strings on the
module.

With bleeding edge releases you will now get:

$ sudo grep '' /sys/module/compat/parameters/compat_*
/sys/module/compat/parameters/compat_base_tree:linux-next.git
/sys/module/compat/parameters/compat_base_tree_version:next-20100517
/sys/module/compat/parameters/compat_version:compat-wireless-20100517-7-ged07f6b

The respective output upon load is:

Compat-wireless backport release: compat-wireless-20100517-7-ged07f6b
Backport based on linux-next.git next-20100517

If there are any questions please let me know.

On a final note thanks to all those who have contributed to this
2.6.34 release of both the generic kernel compatibility module and
compat-wireless, specially to Haukes and Pavel.
