can't compile latest compat-wireless under kernel 3.2 even using git

[Alfonso Fiore]

Hi,

I tried to download and compile compat-wireless from git:

git clone git://git.kernel.org/pub/scm/linux/kernel/git/next/linux-next.git
git clone git://github.com/mcgrof/compat.git
git clone git://github.com/mcgrof/compat-wireless.git

export GIT_TREE=/storage/wireless/linux-next/
export GIT_COMPAT_TREE=/storage/wireless/compat/

cd compat-wireless-2.6

./scripts/admin-clean.sh
./scripts/admin-update.sh (this command is successful)
./scripts/driver-select
./scripts/driver-select rt2x00

make

I get the "same" error:

$ make
./scripts/gen-compat-autoconf.sh config.mk > include/linux/compat_autoconf.h
make -C /lib/modules/3.2.0-interlaced2+/build
M=/storage/wireless/compat-wireless modules

Any help is greatly appreciated.

This is all correct.

What kernel are you compiling against? skb_complete_wifi_ack() is not
declared in linux kernel 3.2.2, just in 3.3-rc2. It looks like the
kernel you are compiling against has some modifications conflicting with
compat-wireless.

With some tricks I managed to compile compat-wireless against my
custom kernel, but that didn't solve my problem. Apparently when I
thought the latest compat-wireless fixed my problem I was wrong, it
was just a random glitch.
Or most probably I completely screwed up my drivers by juggling two kernels.
Anyway, I booted with 3.0.0-15, recompiled (with make clean) both
(rebooting each time) compat-wireless-3.3-rc1-2 and
compat-wireless-2012-01-26 and I still get a very limited performance
over wireless (max 300 KB/sec).

*** Is there a chance to activate some logging that could give you an idea

Twice, randomly, I've seen it going as fast as wired (accessing the
internet) so I imagine it's something than can be fixed.
I also test both speedtest.net and wget from a local mirror, so it's
not a fluctuating link.

In case you wonder how I compiled the git version of compat-wireless
for my custom kernel, here is how (and it works, but with the same
sub-standard performances as compat-wireless-2012-01-26 under 3.0.0):

Ok so first I compiled linux-next:

cd linux-next/
cp /boot/config-3.0.0-15-generic-pae .config
yes '' | make oldconfig
make-kpkg clean
CONCURRENCY_LEVEL=`getconf _NPROCESSORS_ONLN` fakeroot make-kpkg
--initrd --append-to-version=-linux-next kernel_image kernel_headers

then I went into my current kernel and changed links:

cd /lib/modules/3.2.0-interlaced2+
sudo mv source source_true
sudo mv build build_true
sudo ln -s /storage/wireless/linux-next source
sudo ln -s /storage/wireless/linux-next build

then I compiled compat-wireless

cd /storage/wireless/compat-wireless/
make clean
make (compilation went well)

then put back the links:

cd /lib/modules/3.2.0-interlaced2+
sudo mv build_true build
sudo mv source_true source

and installed compat-wireless:
cd /storage/wireless/compat-wireless/
sudo make install

thanks for any idea,
alfonso

Most drivers and the wireless subsystem itself have some config otpions
to activate debug output. Search in the config.mk in compat-wirless for
the debug options for your devicve and activate them by editing
config.mk and rebuilding compat-wireless

Now it is interestingly to know what Wifi device you are using and what
Access point.

That looks bad.
The easiest and safest ways would be to remove the skb_complete_wifi_ack
backport from include/linux/compat-3.3.h in compat-wireless.
