Of course it's not anywhere near good shape.  Almost all items from my
review were completely ignored, and we have another totoally substandard
wireless driver with crappy thread handling, a huge number of broken private
ioctls and partially absymal codingstyle.

And I didn't even get a reply to my mail addressing the concerns above.

 - things like 11d.[ch] don't have business of being in a driver,
   this should be somewhere in common code.

There is no common code for this.  mac80211 will eventually grow a
utility library that libertas will hopefully be able to attach to.

 - please get rid of the ENTER/LEAVE macros

People have said that many drivers do this, and it's quite useful for
debugging.

 - please get rid of all your private ioctls and iwpriv stuff
   (should I add !!!! here)

Any ioctls that have equivalents in WEXT or ethtool can certainly be
removed.  Mesh ones like fwt_reset, bt_reset, mesh_get_ttl, etc have no
current equivalents and will need to stick around.  I've already removed
all the ones that were relevant for WPA and moved them to standard WEXT
calls.

 - most of types.h should not be there but you should be using
   the types from include/linux/*80211*

I've already updated libertas-2.6 git with a ton of updates for this.

In any case, lets push off any merge until 2.6.23 so the rest of the
comments can be dealt with:

 - the __le* annotation issue you mentioned in the mail is important.
 - there shouldn't be a LICENSE file in individual driver directories,
   especially if it's just plain old GPLv2.
 - please get rid of setting -DFOO flags in the Makefile, just use
   these directly as config symbols.
 - there shouldn't be a README file in the driver directory, this
   should be in Documentation/
 - please don't use wlan_* foo types.  a) this should be structs, not
   typedefs, and b) wlan is an utterly generic name for beeing inside
   a driver.
 - there seems to be lots of tabs vs spaces messups
 - there's an awful lot of headers without clear divided
responsibilities,
   there should be only a few ones left (internal interfaces and hw
   interface basically)
 - having lowercase names for lots of hw commands is a very bad idea
   for readability
 - etc

This is leading from behind :/  We don't need to blow about in the wind 
here.  If you reviewed the driver in depth -- which I assumed because of 
the trust placed in you as wireless maintainer -- then this situation 
really should not be happening.  You need to know the status of new 
drivers you are pushing upstream: what work is left to do, what has been 
done, what state the driver is in.

I view this request as a failure of the trust network :(

For my part, I _did_ review it.  Twice.  Once in the early days, and 
once when I pulled it into my netdev-2.6.git tree.  libertas needs the 
changes mentioned in this thread.  But the driver is in workable shape 
to be USED while being improved.  I strongly dislike people being cowed 
into not merging a driver for years, because the driver in question does 
not meet Christoph's idea of perfection.

Open source is about release early, release often.  Not "hide code in a 
dark corner until Christoph thinks it is perfect."  We have high 
standards for upstream merged code, but that standard is not perfection. 
  Perfect is the enemy of good.

I would rather see the libertas-2.6 git changes pulled into upstream, 
and am not inclined to revert a WORKING DRIVER at this point, a driver 
that is actively maintained and has seen quite a bit of improvement 
since it initially appeared.

IMO, Linux users best served by avoiding this silly song and dance, now 
that the driver is upstream.

Plus, that leaves the kernel history less polluted.

Perhaps I was a bit hasty.  Given Dan's response I thought that I
had missed something.

But, you are right -- the driver works now, and Dan and company are
sure to be around to keep working on it.

Consider the request withdrawn.

Ok, somebody make an executive decision then.  As it stands, the driver
_does_ work.  Everyone understands it needs the cleanups that Christoph
has mentioned, and those of us who work on it certainly will keep
cleaning it up to hopefully match Christoph's expectations.  Some of
that has already been done in upstream git.

So, either we push it off until 2.6.23, or it gets merged as-is and we
clean it up as we go along, which we'll certainly do.

Um, it was merged a while ago.

That's why John's email, and my own, are discussing the revert of the 
driver, not the merge of the driver.

The executive decision has been made.

It's a shame to expose new ABI bits that we expect to change to
mainline. Getting rid of obsolete interfaces is next to impossible so
the introduction of new interfaces really does warrant serious
consideration.

Can we come up with a scheme to keep the new ioctls introduced by this
driver from leaking over into distro-land before they get reworked?
Like preemptively adding a deprecation printk?

And it isn't only ioctls, but just having code there to set a bad
example, and added overhead of maintaining APIs used by the
driver.

Two things on top of a lot of people's pet peeves list are lack of
good review bandwidth, and poor driver code! So it is sad this was
merged without Christoph's comments being addressed. "it works for
me, we can fix it later" is probably a big reason for quality
problems of some parts of the kernel.

As for Christoph's idea of perfection... it usually isn't a bad
thing. And he is quite reasonable if you explain your good reason
to disagree or do something differently. The attitude of ignoring
comments can be really demotivating for a reviewer.

I guess it's a good thing that the maintainer was not ignoring the

Please. This has nothing to do with Christoph. (1) the driver seems to
break every Linux coding style convention known to man and (2) adds a
new ABI with bunch of ioctls() that apparently haven't been reviewed
properly. That's just not acceptable for mainline kernel!

I completely agree, these things should be corrected and if the the
author is being totally unresponsive to Christoph's review that's even
worse.

Every piece of code that I've written that Christoph has reviewed has
become significantly better because of his review.

Um, the maintainer replied yesterday morning[1] that libertas-2.6.git 
has already been updated for these requests, will be updated some more, 
and overall was responsive to the entire list of Christoph requests.

I'm mainly concerned with removing the unnecessary ioctls before 2.6.22 
release, since that affects userspace.  The vast majority of other stuff 
is cosmetic, which is being worked on, but lower priority in my book.

I'll audit the list of ioctls and remove ones that may be objectionable,
and we'll go back through them after 2.6.22 and add back in ones that
are actually required.  Keep the API/ABI small and expand if necessary.
What's the timeframe required here?  Linville said a few days at the
most.

Ideally, before 2.6.22-rc1.  No set date, but generally it's a week or 
two after merge window opens.

But even if you miss -rc1, we MUST get in the ioctl removal before 
2.6.22 release.  This is certainly exception to the "nothing but bug 
fixes" rule -- or perhaps it is following the rule, if you consider the 
ioctls' existence a bug :)

Getting the CodingStyle fixes in before 2.6.22-rc1 would be nice, but, 
as I noted, lower priority than serious stuff like ioctl consideration.

There is also a bunch of updates pending. I'm sending them over this

I'm going through the ioctls as we speak...  what else was pending?
Louis has a few on libertas-dev list.  We also need to pull wireless-2.6
into libertas before we send linville a pull request, I think.

I can fix those up; but setting KBUILD_VERBOSE=1 and recompiling doesn't
show any of them in current libertas-2.6; -Wall is definitely defined.
Is there another way to enable something give yet more verbose debug
output?

The copious libertas warnings are present in vanilla upstream 
linux-2.6.git.

Just do "make allmodconfig && make -sj4".

	Jeff


P.S. Make sure libertas is free of sparse warnings, as all drivers 
should be.  Read Documentation/sparse.txt.

Sparse stuff fixed.  Still getting working on 64-bit compiles.

No, I think that it's just host arch. and/or gcc dependent.

I built on x86_64.  Can you do that?
