Kernel bug in bcm43xx-d80211

[Alex Davis]

I go the following Oops with the latest wireless-dev git when starting wpa_supplicant:

Probably caused by my recent changes that accidentally broke d80211
pretty much completely. Patches are on the linux-wireless mailing list.

Wireless topics moved from this list to linux-wireless@vger.kernel.org.
Broadcom drivers are discussed in bcm43xx-dev@lists.berlios.de.
wireless-dev is horribly broken, and the fixes haven't been merged yet.

The current Broadcom driver can be loaded from
http://bu3sch.de/git/wireless-dev.git (please load it on top of
wireless-dev.git to save bandwidth)

It doesn't include the latest breakage from wireless-dev, but it does
include some important fixes.

Although I haven't seen a problem like yours, I strongly suggest that
you try the above repository and post your results to the bcm43xx-dev
list.  Even if the results are more positive :)

Johannes, would it be possible to commit patches faster, please?  Now
that I told Michael about git-update-server-info, his changes are
downloadable as soon as he makes a commit.  wireless-dev.git, on the
other hand, is a mess and has been for some time (since Friday, I
believe).

It is a problem for projects like DadWifi that recommend to use the top
of wireless-dev.git.  Yes, I know, breakage is unavoidable to a certain
degree, but it shouldn't come to the situation when the patches are
known, nobody objects, yet the repository stays broken and all newcomers
have to be told about the problem.

That's not to offend you or anyone.  It's just something that would help
a lot.

I don't commit to wireless-dev, John does. I'd love if the patches were
in already ;) And I think he even said he had committed them but they
didn't show up so something must have gone wrong (forgot to push out to
kernel.org maybe)

actually, get Jiri's
(http://www.kernel.org/git/linux/kernel/git/jbenc/dscape.git), he's just
committed the fixes.

To merge it in, just git-pull it (and see the docs)

While in the wireless-dev tree, issue the following:

git branch michael
git checkout michael
git pull http://bu3sch.de/git/wireless-dev.git master

To get back to the original wireless-dev tree, us a 'git checkout master' command.

You need to pull the 'up' branch :-)

This should do it for you:

git-remote add bcm43xx http://bu3sch.de/git/wireless-dev.git
git-branch bcm43xx
git-config branch.bcm43xx.remote bcm43xx
git-config branch.bcm43xx.merge refs/heads/master
git-checkout bcm43xx
git-pull

Sorry, I didn't expect it to be so hairy.  Perhaps it should be
documented somewhere.

I appreciate all the help, but now I'm confused. I got these instructions from Larry Finger:
git branch michael
git checkout michael
git pull http://bu3sch.de/git/wireless-dev.git master

And these instructions from Pavel Roskin:
git-remote add bcm43xx http://bu3sch.de/git/wireless-dev.git
git-branch bcm43xx
git-config branch.bcm43xx.remote bcm43xx
git-config branch.bcm43xx.merge refs/heads/master
git-checkout bcm43xx
git-pull

Which set of instructions do I use? Are either of these still applicable, seeing as I was asked
to pull from Jiri Benc's tree?

Thanks

The only difference is that I provided git-remote and git-config
commands that would change the configuration to make "git pull" work
every time without arguments on both branches, whereas if you follow
Larry's instructions, you'll need to provide the URL and the branch to
merge every time you are on the "michael" branch.

The name of the branch is different, but it's your choice.  "git-XXX" is
equivalent to "git XXX", but I prefer the former because bash will
complete the command.  Again, it doesn't really matter.

This is easier for one-time pull.

This is useful if you want to pull regularly. But Larry's way can be used
even in that case - I'm pulling regularly from wireless-dev and never used
git-config :-)

Also, Larry's advice about getting back to the original wireless-dev tree
could be useful for you. It applies to both Larry's and Pavel's
instructions.

If you pull from my tree, you won't be able to compile any d80211 driver.
The wireless statistics fixes need to be committed by John first.

I merged Michael's changes. It doesn't panic anymore, but I still can't=
 associate. Here's the

Another thing I've noticed: the output from iwconfig is corrupted:

Re: Kernel bug in bcm43xx-d80211

I'm sorry!  I didn't realize git would be merging two branches.  I did try my
commands, but I didn't notice the message about merging.

If you merge two branches, you are pulling the bugs from wireless.dev into the
bcm43xx branch.

You need to remove the merge by resetting the local branch to the remote branch.
 Please use this command:

git-reset --hard remotes/bcm43xx/master

bcm43xx is the name you used in the git-remote command.  Perhaps we need some
kind of git wrapper to deal with all that complexity of having multiple remotes
in one repository.  I'll ask in the git list.  It doesn't look like an exotic
case anymore.

Once you have reverted the branch, disable CONFIG_CFG80211 in .config - it's not
ready yet.  This would fix the iwconfig output.

As for association timeout, it's probably unrelated, bit it would be helpful if
you recheck it on clean sources.  It's possible wpa_supplicant doesn't get the
AP MAC address properly.

I don't think that's actually true, the iwconfig output typo bug is
present in that part of the code that is always enabled whether you have
CFG80211 or not. You're just assuming that it would fix it because it
did weeks ago ;)
