I'm still 1600 messages behind in reading the list, but I have spent
enough time reading the discussion about GPL and drivers that I feel
compelled to comment. I don't intend to comment further because I don't
want to contribute to a flamewar any more than this already will. But I
feel the need to defend those who contribute to Free Software against
those who don't.
The argument I have been reading has been centered around the idea of
working around the GPL to support binary-only driver and various other
things which are counter to the spirit of the GPL and Linux. But
someone who is trying to find a legal GPL loophole is not considering
the root of the situation and that the GPL is an effect, not a cause.
A point someone else made that I feel compelled to reiterate is that it
is the nature of the Linux development model and the attitude of the
developers which has made Linux what it is and has made you want to use it.
But I have another point. You are not dealing with a license here. The
license is there to satisfy lawyers and make clear the INTENT of the
authors. The keyword here is INTENT in that someone who has developed
something is telling you how they feel about the use of their work
which, under many circumstances, they could have chosen not to share
with you. What you are dealing with is real people who have put an
incredible amount of time and effort into developing Linux. Those
people, to whom you owe much respect for sharing their contributions,
have decided that their software should be used with certain
restrictions, that being the GPL. If you abuse Linux, it is not the GPL
that you are insulting, but the people who developed Linux.
The GPL_ONLY restriction for driver modules may seem unfair, but it is
far from it. There are both valid technical and philosophical reasons
for working that way. No one forces you to use Linux, and when you made
the choice to use it, you are entering into a community with a specific
philosophy. You know that philosophy in advance, so when you discover
that you have a restruction you don't like, you have no room to complain.
As someone said, if you want to write drivers for a UNIX which does not
have these restrictions, there are plenty of commercial UNIXes out there
that you have to choose from. The fact that they are perhaps less
popular is one reason why Linux developers do not want to imitate them.
So, the discussions about finding ways to make a non-GPL driver look
like a GPL driver and get away with it legally are all moot. The reason
you should not violate this is because the architects of Linux do not
want you to. If you choose to violate that, you are being unethical,
pure and simple. Or more to the point, you're being an asshole to a lot
of hard-working people who have chosen to freely share their work with
you. Since they are the authors and you are not, their feelings about
their softare are more important than yours. You may be able to screw
them over and get away with it -- people do that sort of thing all the
time -- but the fact that you may find a legal loophole doesn't make you
any less of an abject asshole.
In short: Be honorable.

In other words, information does not want to be free. You shouldn't use
code the way you want to use it but the way the authors want you to use it.
After all, they didn't have to give it to you if they didn't want to.
However, Richard Stallman does not agree with this view. It's his view that
if the authors chose to give you the code, you can use it any way you want
to, regardless of how the authors feel about that type of usage. This is why
he created the GPL.

If you really believe that the Linux authors wished to continue to control
how their code was used, you have to think that they were stupid to release
the code under the GPL. After all, the whole point of the GPL is to prohibit
such restrictions. The reason Linux is under the GPL is so that developers
*can't* put restrictions on how the package can be used. That's the "open"
in open source.

The person who tries to put other people's GPL'd works under his license
restrictions is the asshole. I have contributed code to the Linux kernel
under the GPL license (bonus points to anyone who can find my 25 lines of
code or so). It is nobody else's right to add code to my code and add usage
restrictions to it. The GPL expressly forbids this.
> Since they are the authors and you are not, their feelings about

I'm just baffled. You don't seem to understand at all why the Linux kernel
is organized under the GPL. It's precisely so that some developers can't
hijack the project and encumber the growing source base with usage and
distribution restrictions.

The asshole is the person who thinks that they have the right to change the
express wishes of all the other contributors to the kernel who chose to
contribute to a project that operates under the GPL license. The GPL license
is about there being no restrictions on usage.

Use in any way you want to is the BSD license, not the GPL. The GPL

Please show me one restriction on *use* in the GPL.
"Activities other than copying, distribution and modification are not

Yes, it restricts your ability to distribute and your ability to create
derived works if and only if you distribute those derived works. It places
no restrictions whatsoever on use. And since it requires distributors to
place no restrictions not in the GPL, distributors cannot place *any*
restrictions on usage either.
DS
In many ways the original intention of the debate was lost in the battle.
There are a lot of zealots on both sides of the GPL debate - personally, my
undertanding is that the GPL forbids usage restrictions, thus once you
release code under the GPL you cannot control it. This seems especially
important in a project, such as Linux, that has been collaboratively
developmed by a whole community.
The original question was would a binary driver interface allow easier usage
by 'normal' users with any compatible kernel (rather than specific versions)
and perhaps simplify module development cycle?
Would the performance hit involved be worth the potential
compatibility/simplicity?
A lot of people have, assumed that this is a call to arms for binary-only
modules. This is not true although this type of change would make such things
more common.

That is a restriction on distribution, not use. You may use GPL'd code to
produce a derived work and you may use that derived work. The only
restrictions kick in when and if you distribute that derived work.
> Use of the code, not use of

The GPL puts no restrictions on use. The GPL_ONLY stuff does.
It's really this simple: The GPL says you can use the code for whatever you
want. It also says that if you want to distribute the GPL'd work or works
based on the GPL'd work, you may not impose any restrictions other than
those imposed by the GPL. It very specifically prohibits restrictions on
mere use or upon the mere creation of derived works. All of its restrictions
kick in on distribution.
The GPL_ONLY stuff is an attempt to restrict use. There is nothing
inherently wrong with attempts to restrict use. One could argue that the
root permission check on 'umount' is a restriction on use. Surely the GPL
doesn't mean you can't have any usage restrictions at all.
What it does mean is that such usage restrictions *cannot* be licensing
restrictions. In other words, it cannot be a license violation to remove
them or circumvent them. So long as nobody tries to claim the GPL_ONLY is a
license enforcement technique, there is no dispute.
However, some people seem to be arguing that the GPL_ONLY symbols are in
fact a license enforcement technique. If that's true, then when they
distribute their code, they are putting additional restrictions not in the
GPL on it. That is a GPL violation.
Other people who contributed to the Linux kernel relied upon the GPL
license to ensure that their code, and works derived from it, would be
available *without* use restrictions. Nobody has the right to turn around
and impose usage restrictions on the Linux kernel source code.
The GPL prohibits the imposition of any licensing requirements other than
those contained in the GPL itself, all of which kick in only upon
distribution. It's really that simple. Anyone who distributes the Linux
kernel with a licensing restriction that kicks in on mere use is violating
the GPL.

Sure, and you may not *use* GPL'd code to produce a derived work and bring
a firearm into a court of law. I asked for a restriction on *use*, not a
restriction on use and something else.

No the GPL_ONLY stuff is an attempt to document that there is no conceivable
way that using a given symbol does not create a derived work.
If you use an unmodified kernel it is only a one liner to ensure it does
not complain about your code. So this only shows up as a real
impediment when code that uses the symbol is distributed.
Beyond which copying code into the kernel is when this is checked so this is
a valid place to check things. There is a strong tying between using
programs and copying them into memory. And that copying is the
justification for most usage restrictions even in commercial software.
The code is also quite a small nit that really should not affect
anything.

So long as it's not an attempt to use the GPL license as a way to restrict
use, there's no problem. There is no license restriction or enforcement
scheme here that one could possibly circumvent because the GPL_ONLY stuff is
not a license enforcement scheme. It cannot be a license enforcement scheme
because there are no license requirements that kick in upon any act other
than distribution.
The GPL_ONLY stuff does in fact restrict use. However, this is a
restriction anyone is free to remove or circumvent if it bothers them. This
isn't a dishonorable act because nobody intended this mechanism to restrict
use -- I hope.

If effect it does affect use because of lack of support. But personally I

EXACTLY. Fortunately in this case, the authors place few restrictions
on your usage. Indeed, the "restrictions" are more a matter of being
nice to the people who made the stuff you're using.
You're stuck thinking about "law" and "rules". I'm thinking instead
about "honor".
One of the (unresolved) discussions I had with RMS involved the role of
the author. He believes that the user is more important than the
author. I believe the author is more important, because had the author
not written what the user has, then the user would not have it!
Actually, he partially agrees with me but does not feel that the author
should be able to apply restrictions (IF the work is PUBLISHED).

But it seems clear to me that the GPL places some very strong
restrictions on your usage. Those restrictions are that although your
specific usage of the code doesn't matter, anything (published) that you
derive from GPL work MUST also be published under GPL.
So my point is that when someone publishes something under GPL that you
find useful, give respect to the person who wrote it by obeying the
spirit of the license. But it is not the license that is important as
that the author chose to release his work under those terms. People,
not rules; honor, not law.
There are other licenses besides the GPL. When authors release under
those terms, you should respect those terms as well. The thing that
sets the GPL apart from, say, closed-source licensing is that the GPL is
based on a system of honor, while proprietary systems can (and often do)
become unfairly restrictive to the users.

The restrictions they are applying are the only ones in the GPL. It was
smart for them to use the GPL because it is compatible with their
wishes. Follow the GPL not because the GPL is a copyright license, but
because you are grateful for the efforts of those who published under GPL.
Furthermore, if someone publishes under GPL, and your insult them, they
may become less willing to release under GPL, thereby limiting your
ability to rip them off.
Also, just to be pedantic, because you mentioned RMS, "open source" and
"free software" are not the same thing.

And I completely agree with all of this. I'm getting the feeling that
you and I don't actually disagree on any of this. :)
The point of divergence is with regard to modules and the symbol
restrictions for non-GPL drivers. Here is a gray area where the GPL may
not apply really. These gray areas are where ethics and honor must come
into play.

Which is precisely why those authors placed Linux under the GPL. If
they didn't like that, they would be working on proprietary OS's. I'm
saying that people should respect the authors by honoring the GPL.

Well, aside from the "it must remain free clause" (which I interpret as
an important restriction), I agree with you. That is to say, the
"contributor" who hijacks the work of other contributors is being
dishonorable, because he is not respecting the other contributors.

I don't think anyone was talking about use of applications, but rather

Agreed. GPL_ONLY is not a license restriction. It is a technical issue.
Binary-only modules are inherently untrustworthy (no open code review)
and undebuggable. It is therefore of technical merit to restrict both
what they can access in the kernel (GPL_ONLY) and limit how much kernel
developers should have to tolerate when they're involved.
But beyond this, there are some social issues. If someone finds a way
to work around this mechanism, they are breaking things to everyone
else's detriment. For a commercial entity to violate the GPL_ONLY
barrier is an insult to kernel developers AND to their customers who
will have trouble getting problems solved.
So, if a company works around GPL_ONLY, are they violating the GPL
license? Probably not. Does that make it OKAY? Probably not.
This is like finding a way to give a user space program access to kernel
resources. There are barriers put in place for a REASON because people
make mistakes when they write software. If no one did, we wouldn't have
any need for memory protection, would we.

This is a publication restriction, not a usage restriction. Your phrasing
above is like saying, "you can't put bullets into a gun that you use to
shoot a police officer". The restriction is on the shooting, not the
loading.
Again, quoting the GPL:
Activities other than copying, distribution and modification are not
covered by this License; they are outside its scope. The act of
running the Program is not restricted, and the output from the Program
is covered only if its contents constitute a work based on the
Program (independent of having been made by running the Program).
Whether that is true depends on what the Program does.

I think you are all missing the point. This isn't a Linux kernel
problem. This is a customer and distributor problem. If Red Hat,
Mandrake, SuSE, etc., choose to remove these GPL_ONLY() barriers
and release the new "free" code under GPL, they're entitled. Heck,
they can even add in new ones in their own kernels.
I'm surprised you are even discussing this issue on this list.
If third party developers are restricted based on GPL_ONLY(),
they can either (A) release their product under other OSes or Linux
distributions without the GPL_ONLY() restrictions, (B) modify their
product to be more GPL-friendly, or (C) avoid Linux support entirely.
It ultimately means either more support for third party products with
one distribution over another, which may or may not be financially
beneficial to that distribution, or it means that some Linux
distributors continue to supress supporting new third party devices
that don't believe in the GPL. Either way, it's a distribution
decision based on open-source beliefs and how that balances with
financial benefit (both of which would matter to me as a stockholder).
This really has nothing to do with the Linux kernel code itself.
Very few customers that want third party device support will go to
vger to roll their own kernel -- they'll go to a Linux distributor,
get them to include device support and pay for it (or start with a
Linux distribution and roll their own).
So include GPL_ONLY(), don't include GPL_ONLY(), whatever. If you
don't like it, Mr. Customer, find a Linux distributor that will
fix the problem for you.
If you want to create a new driver model that supports third party
devices without regard to their GPL status, make a patch. Who
knows, maybe some distribution will actually start using it. But
don't even think about bugging this list to get it included by
default (too many GPL purists out there).

Linux vendors have already recieved, and decided to act on cease and
desist letters involving adding hooks (ie EXPORT_SYMBOL stuff) for non
free modules that were not in the base distro. I think that speaks for
part of the legal view.

Who is sending these letters? Who has no respect for the GPL and seeks to
add additional restrictions? IMO, these letters are almost as bad as the SCO
letters. Nobody has any business putting additional licensing restrictions
on code was placed under the GPL.

I don't know who but i can say that Linus or anyone he
assigns can do so based not on GPL but on trademark. That is
to say that while it wouldn't be a violation of the
copyright license to distribute such modified code but it
would be within the rights of the trademark holder (Linus)
to refuse them the _privilege_ of calling the modified code
Linux. Not only would it be within his rights but it is
necessary for him to define and enforce restrictions on what
may be called Linux or he would lose that authority.
Just like you can make a copy of Red Hat's distribution but
without Red Hat Inc's explicit permission you cannot call it Red
Hat or Maroon Chapeau, etc. For that matter the Open group
could, in theory, deny SCO the privilege of of calling their
own products UNIX.

This is no additional restriction.
Check your history. The linux kernel was always under the GPL, not the
LGPL ie distributing stuff that links with the kernel means this stuff
must be distributed under the gpl.
At some point Linus decreeted linking closed modules was ok with him
(note this was done without consulting anyone, so others contributors
could have objected - they did choose to release stuff under the gpl
after all - but this being Linus they let it pass)
At a later point however the scope of closed linking had grown so big
people started saying enough is enough and GPL-ONLY was born with
Linus's approval.
It is not a licensing change. It's an hint the associated kernel symbols
are not covered by Linus' previous informal exemption and full GPL rules
apply. To avoid rewriting history symbols that could be used in non-free
stuff previously are not GPL-ONLY. People that ignore the hint can and
will be sued (people that link to symbols not GPL-ONLY could be sued too
but everyone seems to have agreed to let it pass). Removing the software
GPL-ONLY checks or working around them has nothing to do with it - it
does not change the basic kernel license nor the stated intentions of
its authors to enforce it. Hiding a do-not-trespass sign does not give
you the right to do it (if you think so do a reality check).
So please stop making horrified noises the GPL is being enforced in a
GPL project. Don't you realise how ridiculous it is ?

Yes, *distributing* stuff that links with the kernel means this stuff must
be distributed under the GPL. Note that this is a restriction that only
kicks in when you distribute something. It places no restrictions on how you
can use derived works you don't distribute.

Sued for what? Violating a restriction that isn't part of the license?
That's no more illegal than removing the security checks on 'mount'.

Except that the GPL does not permit any usage restrictions.

All of the GPL's restrictions kick in upon distribution. The GPL_ONLY
restrictions affect use even in the absence of distribution. Thus, the
GPL_ONLY stuff *cannot* be a license enforcement because what it enforces is
*not* part of the license. Anyone who distributed Linux claiming that it had
such a license restriction would be in violation of the GPL's prohibition
against distribution with additional restrictions. Can you please reply to
that specific argument?
And this is not some whacko obsure legalistic argument. This is a
fundamental point. Many people who contributed to the Linux kernel
contributed *because* they believed in the GPL and felt assured that nobody,
not even Linus, could close the evolving works by putting usage restrictions
on it. You GPL a work because you want to keep not only the current code
open to unrestricted use but all future distributed derived works as well.
Nobody has the right to add new license restrictions beyond those present in
the GPL.

FUD, Inc. If these really did exist, they would be more commonly
known and I'm certain would affect customer choice. IMHO, I think
this is the vendor's (and I specifically think of Red Hat) way of
excusing themselves from having to work with third party vendors
in order to cover themselves legally with groups like the FSF.
Whether that's true or not, or if there is some other developer
contingent at these distribution houses that is preventing the
EXPORT_SYMBOL{,GPL}() changes due to personal bias, I don't know.
And I doubt we'll ever know.
These letters are like WMD -- they exist, you know they do, but you
just can't find them. :)

Indeed. The GPL may not be perfect, but IMHO the GPL is the only way to make
sure everyone plays the game according to the rules. I.e. I give you something,
you can use it, but please play according to the rules of fair play.
BSD may look OK, but it doesn't protect against people who don't (want to) play
according to the rules.

I consider binary-only modules some kind of loophole to avoid playing according
to the rules of fair play.
Unfortunately it seems to be almost impossible to design a license that forces
you to play according to the rules of fair play, and doesn't have any
loopholes or grey areas.

Sued for not infringing the software license, in this case the GPL. They
won't be sued for removing GPL_ONLY checks ; they won't even be sued for
using GPL_ONLY symbols. They will be sued for distributing a non-GPLed
derived work when the license forbids it.
A symbol is marked GPL-only :
1. when there is no bloody way it could be used in another work without
it being a derived work
2. when the author of the associated kernel code publicly stated he will
go after you if you do not respect the license.
All the software "workarounds" proposed are only ways to infringe
without getting a big red warning in the face. They do not change the
reality of the infraction per see.

There is no usage restriction - you have the code, you can remove the
checks if you want to. Unlike a license enforcement restriction you
won't be sued just for this.
Now the next step is usually to link a big fat closed module to your
modified kernel. And there you *will* be sued if you distribute the
resulting work (which pisses of some unethical corporations because the
sole way to do it legally is to have the end-user perform the operation,
and the end-user does not want to bother with it. ie its closes them
some markets unless they open up their stuff. Guess what ? You won't
find any people on this list cry for them).
I even suspect if you submit a patch to have GPL-ONLY a kernel build
option it will be accepted (provided it taints the whole kernel
probably). Distributions of course will never ship binaries build
without it, and appliance manufacturers that use it will be submitted to
heavy review, but that's already the case.

Prove an original work which uses the proper "unprotectable API" to
operate in the Linux kernel is a "derived work".
You can't and never will. It is an "original work".
"Original works" are exempt, what is not clear?
Oh I get it, because it happens to work in "Linux" it is not an original
work? What a lame cast of mental giants.

Other contributors objected at the time. Furthermore there is merging of
third party GPL code from bodies like the FSF who also object and didnt
submit their code themselves.

No. Sorry its neccessary to keep correcting people here but I have no
intention of allowing anyone creating a derivative work to claim
estoppel when they get their arses kicked some years on. Their sole
defence is that the work is not derivative. In some cases I can believe
that could be a valid claim.
As to _GPL. Its primarily a way of ensuring people who mix binary code
in with their kernel in unsupportable ways are made aware of it, and so
we can all use filter rules to discard their bugs.
Some vendors do support certain third party binary modules in some
specific enterprise configurations, others don't. In the community case
the general rule is we don't.

It has happened. If you want to call me a liar feel free. Its your right
in a free society. It doesn't change the facts however.
Adding hooks for a proprietary module is a dubious practice. Doing it as
part of a two way arrangement with a proprietary vendor producing a non
free module is extremely unwise indeed.

Nobody I've talked to (legal folks included) seems to think they are
additional restrictions, merely people enforcing their copyright rights
against folks working as a group to conspire to create a derivative work
prohibited by the GPL.

Bzzit ... GPL_ONLY stuff is an attempt to retrict usage by removing access
to the unprotectable API. And for anyone claiming there is not API to
protect, the kernel source is the manual to the API. The foolish intent
and design to hide the API has caused the kernel itself to become the
manual.
This is even obvious to people, like myself, who are not lawyers.

Then allow the usage and functionality of the SYMBOLS and not "steal" them
from usage. If you say thay can be used without support.
PS it is "The Troll" again.
Just execute the reject of the License and have the means to reject
support. You are so full of it to say it is for rejecting support when
anyone knows it removes usage of the SYMBOL == API.

Fair play is awfully hard to define. Fair use likewise. Currently almost
all countries legal systems have a clear notion of "derived work", and
copyright (unlike patents) extends no further. That limits how far the
GPL can extend, but its the same line in the sand (well fuzzy patch in
the sand in truth) that stops a lot of other things you wouldnt like.
Which and what modules count as derivative works is a lawyer question
and not it seems a trivial one.
Patents do extend beyond just the derived work and since Linux contains
patented material with rights granted for GPL use as per the GPL(but not
for non GPL use) there is a murky area around modules and patents - one
example of the issues that raises being RTLinux.
Folks using binary modules may also find third party software licenses
invalid (eg the OpenMotif one)

Wait I forgot TFM became GPL_ONLY so you can not read it freely anymore.
Try getting support from RedHat without a support contract, LOL.

Timothy,
Who is talking about using "GPL source code", that is a given NO NO!
Calling symbols in the header files used as the generic functionality of
the kernel is all one could use in "Driver Model". Beyond the simple
usage of header files, one is no longer in the land of API but usage of
raw GPL source.

Technical if and only if it did not remove the functionality of the
symbol when called.
Since it remove the ability to call and it work, creates a restriction of
usaged. Usage being, one calls the function and it works.

GPL_ONLY violate usage, thus it violate GPL.

I never claimed such a thing. Whether an API is unprotectable or not
is a question for the lawyers.
If people put GPL_ONLY symbol exports in their code, that's their call
to make, is it not? It's their code and they're free to say "well, this
is my code, and if you use this symbol, I consider your stuff to be a

If it has legal value, then it's an additional restriction.

Agreed the total intent by the author is to impose a restriction.
Thus the author by default lost his/her right to use, period.

Derived works are already restricted (when it comes to distributing them,
otherwise none of this is relevant since you can easily locally make
all EXPORT_SYMBOL_GPL be plain EXPORT_SYMBOL). It would be a restriction
on who gets to say what constitutes a derived work and what not - but
that is not governed by the GPL anyway but by the relevant local laws.
The GPL does not and cannot outrank the law. If the law were to say the
authors of a piece of code get to say what is a derived work and what
not, then so it is and nothing the GPL says can stand against it.

If it has legal value in showing the work is derivative thats not an
additional restriction. Its merely showing the intent of the author. If
someone creates a work and its found to be derivative and they didnt
make it GPL compatible they get sued, thats also not an additional
restriction its what the GPL says anyway.
That is the whole point of EXPORT_SYMBOL_GPL, it doesn't enforce
anything and Linus was absolutely specific it should not do the
enforcing. Its a hint and a support filter.

If the work would not have been restricted without it and is restricted
with it and you can't remove it, it's an additional restriction. If not,
what would an additional restriction be?
> Its merely showing the intent of the author.
The intent of the author has no bearing on whether or not a work is
derived.

Show me where the GPL says you have to GPL derived works that you don't
distribute. That restriction is found nowhere in the GPL and if you
attempted to impose such a restriction, it would be an additional one.

If it doesn't enforce anything and isn't a license restriction, then it's
perfectly legal and kosher to remove it.
DS
Alan,
Taking you at face value, as always in the past, how does one parse
between "usage"/"enforcement"?
Can a non-gpl object call, use, and it work "EXPORT_SYMBOL_GPL"?
If EXPORT_SYMBOL_GPL allows functionality, then it does not "enforce" any
license issues. If it is called and then allowed to quietly fail or not
function unless the caller's associated LICENSE is "GPL", then it does
enforce, restrict and prevents 'functional' usage.
If this is a "NEW SYMBOL" one may have an arguement to hold.
If it is an "OLD SYMBOL", or the old one is removed and replaced with an
random new one, yet the core functionality of the operations are the same,
the intent is to break or terminate usage.
If EXPORT_SYMBOL_GPL is to be a notifier to let end-user be aware that a
binary vendor may be operating in a grey region of "derived" work, fine.
Allow it to operate but make noise.
Pretend it is doing the NOVELL thing of exceeding license count, and make
noise.
It is all to simple to bypass, and if the TAINTING issues for detection
is truly only to ignore issues from non-gpl sourced drivers, then great.
I know you have killfiled me by now, but how goes business school for the
MBA? Does this mean you are going to quit Linux?

You can remove it. But if you remove for with the obvious purpose
of abetting the distribution of non-GPL derived work, don't be
surprised to get smacked by courts who don't care for your technical
sophistry.

I've noticed it's become common to say this, but (NAL) I doubt it's
true. I would expect a court to respect the author's intent within
some narrow range that would otherwise be ambiguous. Intent and
community standards play a large role in law. If enough people wear
a path across private property, it can become an easement.

I'll go even farther, and say that one might call the GPL_ONLY
symbols an "effective technological measure" that "effectively
controls access to a work" and "effectively protects a right of a
copyright owner ... in the ordinary course of its operation....".
Bypassing GPL_ONLY symbols, as recently advocated by David
Schwartz and Andre Hedrick, could be considered circumvention of
an effective technological measure. Remember Dmitry Sklyarov,

Erik:
One more thing you forgot!
Before you run around ranting about DMCA and CPRM and making suttle legal
threats. Everyone here knows who put it on the line to gain control of
technology to prevent Content Protection Recordable Media from covering
the storage industry wide. That is correct it was me. I was the one and
only person ever to stand up and have a position to help everyone here to
take control of technology. While all of my hard work was destroyed by
the brain-dead of the EFF by causing it to go underground.
So lets be real clear about your wild swings of DMCA, because the irony
will be back to haunt. Threaten to strike me down with DMCA, what a child
you have become.
So this is where it goes ... Mighty Linux kills usage for business with
lawsuits like the MPAA and RIAA.
GPL == DMCA, this is the brush you swing paint well dude.

Dmitry Sklyarov was put in jail for DMCA.
Erik Anderson joins The Village People to sing "D M C A".
So "The Great 'Erik Anderson'" now threatens former opensource developer
with baiting tactics of GPL == DMCA. This is beautiful.
Richard, I know you will enjoy this one. People are thinking of
enforcing GPL via DMCA. Basically killing the idea that people have the
freedom of choice when it comes to software. Maybe Eben Moglen would like
to comment on this twisted idea of Mr. Erik Anderson.

Wow ... Does "Original Work" have meaning?
Does an "Original Work" using only the standard kernel API headers to
interface mean it is a derived work? You better go find a new lawyer.
"fair usage" of .h files as the API is standard.
Using any .c or kernel C code is a NO NO.

You seem to be somewhat confused as to who needs a lawyer. I'm
not the one asking this question. I am also not the one trying
to make a closed source binary only product that runs within the
context of the Linux kernel, and then complaining that the GPL
wackos are ruining my business... It seems to be that doing such
a thing would be a really stupid business model.
As I recall it is the One True(tm) iSCSI stack you are working
on, right?
> "fair usage" of .h files as the API is standard.
>
> Using any .c or kernel C code is a NO NO.
I invite you to read the COPYING file included in each and every
kernel tarball. There is exactly ONE exception granted in the
linux kernel copyright:
This copyright does *not* cover user programs that use kernel
services by normal system calls - this is merely considered
normal use of the kernel, and does *not* fall under the
heading of "derived work".
All the noise in the world about other exceptions is precisely
that, since the license granting use of the Linux kernel does
not contain any additional provisions.
Anything that can be identified as a "user program" that "use[s]
kernel services by normal system calls" is, by virtue of the above
license grant, doing so with permission and is therefore within
its rights. So you can make all the closed source user space
only One True(tm) iSCSI stacks you want.
Anything that is not a "user program" (and I think everyone can
agree a kernel module is not a "user program") is therefore a
derivitive work.
Anything that is linked into the kernel (and I think everyone can
agree a kernel module is linked into the kernel) and is therefore
interfacing with kernel internals, rather than using "kernel
services by normal system calls" is therefore a derivitive work.
Laugh at people, mock people, rant, rave, wantever you want.
When you are done making noise, please have your laywer explain
how a closed source binary only product that runs within the
context of the Linux kernel is not a derivitive work, per the
very definition given in the kernel COPYING file that grants you
your limited rights for copying, distribution and modification,

Hi Andre,
I'm not a technical person but I've been following the linux-kernel list
for enough years to know who you are and approximately what you have
contributed to the open-source community. Let me start by saying THANK
YOU! I very much appreciate what you do for all of us.
I would like to help you in return, if I can.
I have tried my best for several years to understand your posts and I
simply cannot. I want to understand you because I know you know you
have a great deal to offer -- but I just don't know what the fuck you
are talking about most of the time, no matter how many times I read
your posts.
Please don't be insulted, I beg you. I don't mean to criticize in any
way, but I see that you need help with communication skills. Many of
your posts in this mailing list probably are ignored simply because
very few people understand what you are trying to say.
I'm a married man so I understand how frustrating it is to have every
word misinterpreted. But such frustration should not be necessary in
a technical forum like this one. Anyone who can talk to a disk should
be able to talk to this crowd, but I think you need a wrapper for the
PMLI (Programmer Mailing List Interface).
I can't help feeling that a lot of your frustration is caused by
miscommunciation rather than real issues.
I hate to see you so frustrated and upset when your coronaries are at
risk! Take your heart medication and hire a translator....please!
We are depending on you to be around for many more years.
Pretty Boy,
It is coming and the intent is to return all the stolen symbols.
It is free for anyone to use and enjoy the usage of Linux once again.
So everyone get in line and SUE ME for GPL'ed drivers.

Erik,
Explain how a symbol in 2.4 which was EXPORT_SYMBOL is now
EXPORT_SYMBOL_GPL in 2.6 ?
When you can explain why the API for functionallity in 2.4 is ripped off
like an old lady's purse by a two-bit punk and made nojn-functional in 2.6
you may have a point.
But, you know what, I don't give a damn (DGD).
It is wrong and the original intent when it was discussed was for "NEW
SYMBOLS ONLY". But if distros can add in Symbols for code that does not
exist in the tree, why can't people change them?
But you have a nice day, and do you need a mail address for that letter
you want to send me? Please make it on heavy stock, you need some fiber

It doesn't matter what the symbol is called. I personally agree
with you on this one point -- changing the symbols to use
EXPORT_SYMBOL_GPL type naming is deeply stupid.
I think it is stupid because by implication, it suggests that any
exported symbols lacking such tags are somehow NOT under the GPL.
Per the COPYING file included with each and every copy of the
kernel, Linux is licensed under the GPL. There are no provisions
in the linux kernel COPYING statement allowing non-GPL compatible
binary only closed source kernel modules.
You are therefore, entitled to abide by the precise terms and
conditions for copying, distribution and modification for the
Linux kernel. This entitles you to change symbol names to
whatever makes you feel happy.
But you are also _required_ to abide by the precise terms and
conditions for copying, distribution and modification for the
Linux kernel, which stipulates that unless your code is a "user
[program] that [uses] kernel services by normal system calls", it
is a derived work and therefore must abide by the terms of the
GPL.
Creating and loading such a symbol renaming module is certainly
something you are entitled to do. Using that module for
circumvention of an "effective technological measure" that
"effectively protects a right of a copyright owner ... in the
ordinary course of its operation...." could certainly open you to
legal action here in the USA. I do not hold copyright on any of
the symbols in question, but someone does, and if they do not take
kindly to your circumvention device....
But the DMCA issues are merely an aside to the fundamental
problem. A problem you have avoided in this thread with
gratuitous ad hominem attacks, with the "but Billy did it
first" defence, and similar nonsence.
When you are done making noise, please explain how a closed
source binary only product that runs within the context of the
Linux kernel is not a derivitive work, per the very definition
given in the kernel COPYING file that grants you your limited
rights for copying, distribution and modification.

Erik,
When you can answer why binary only modules are allowed to load regardless
of symbol usage, I will answer your question. Since binary only modules
are allowed to load, this means they are intended to function. If they
are intended to function, they must use the API for standard operations.
Removing the abilty for standard functionality means one does not want
them to function? So if the kernel GPL-ONLY wonder blunders are thinking,
why let them load at all?
Clearly there is a "tainting" process?
If one can detect taint, one can reject loading.
If one reads ./include/linux/module.h
It clearly states any license is acceptable.
So when you can explain about "yes you can but not here", I will explain
the simple rules of how copyright and header files are to be used.
Now what does this have to do with a "freed_symbols" project?
Simple, it restores the symbols back to their original state before
everybody had a whining feast. When they are restored back to original
state then simple usage of the headers compliance to the "unprotectable
interface" is normalized. Go look up 1991 copyright rulings wrt SEGA.
It is all or nothing but both ways is not allowed, what do you think, we
all live in San Francisco?

See above, remove the EXPORT_SYMBOL_GPL crap and then there is no need to
alter or change anything. This restores the original API.

Nice, but "derived work" is bogus and we all know it.

See above, which you agree is stupid, make EXPORT_SYMBOL_GPL go away and
nobody has to deal with API issues.

See above again, nobody has to do anything if the API is restored to it
original format. Thus no changes, no modifications. All of your points
are void.

Truly a dizzying intellect! All my points are void and it is ok
to load binary only modules in the Linux kernel without releasing
source for the derivitive work. And the reason why it is ok to
thus violate the Linux kernel licence is because....
Oh, I guess you forgot the part where you explain why this is
legal. Sorry, but The Great Andre has Spoken isn't good enough.
Sorry, I'm not going to ignore the man behind the curtain.
When you are done making noise, please explain how a closed
source binary only product that runs within the context of the
Linux kernel is not a derivitive work and therefore not subject
to the terms of the GPL, per the definition given in the kernel
COPYING file that grants you your limited rights for copying,
distribution and modification.

Erik postulates a "one MIGHT" legal argument, and gets threatened with bodily
harm? I think you've given up any moral high ground regarding threats.

Maybe if you apply the Bible Code to it, it's clearly stated, but all I see is
a reference that the MODULE_LICENSE macro will accept a parameter of
"Proprietary", and then goes on to say "it's there so the module in question
can be treated properly - just like a Jew in Warsaw in 1941 had to wear a star".
There. I said it. The esteemed Mr Godwin says we're now free to get on with our lives.

The problem is that the kernel has many copyright holders for different
parts of the code, so what the author of module.h wrote can well be
his own opinion but not that of others. Also, if modules are derived
works under the terms of the GPL, the header file cannot change that
fact, no matter what is says exactly.
Once again, it's all up to the lawyers to decide.

Andre,
You seem to be mixing two forms of "use"; the right to use GPL'd source
and the right to use an operational Linux kernel.
You are free to take the source and do whatever you want with it, restricted
only by the terms of the GPL. Other people have the right to do the same.
There is nothing in the GPL that says how a program must behave when
_executing_. Therefore, if you don't like how the resulting executable
operates, _tough_. Your option, and the _freedom_ provided by the GPL,
is to fork the source.
No different than a kernel provided by the Church of Holy Computation
which refuses to operate on Sunday. You may disagree with the
restriction, but surely they are free to add such a restriction to their
kernel source.
As it stands, you are complaining about a _runtime_ restriction; ignoring
your ability to change the source. By insisting that other people remove
checks for license type, you are trying to restrict what others do with
_their_ source. By design, the kernel is already full of runtime restrictions.
There is nothing special about a runtime limitation imposed on modules
lacking the GPL symbol. Just to drive the point home, please consider that there is nothing wrong with a kernel that refuses
to load modules that _DO_ contain the GPL symbol.
In short, fork off...

You are mistaken about what this is. This is not an exception being

the sole author and the Linux kernel does not have a sole author.

This is not a license provision, it's a license interpretation. If you can
show me why the interpretation doesn't apply to kernel modules, please do.

Except it's not a license grant. If it is a license grant, please tell me
who had the authority to grant it.

Hahahahhahaha! Oh, that's too funny. "All dogs are mammals" means things
that aren't dogs aren't mammals? My pencil isn't a "user program". Is it a
derivative work of the Linux kernel in your opinion?

The same way a user program that runs within the context of the Linux
operating system is not a derivative work. A defined interface creates a
license boundary. If you can draw a line between the two works, neither is
derivative of the other.
And you are still ignoring the entire point, which is that it doesn't
matter whether or not such modules are derivative works. The GPL puts no
restrictions whatsoever on the creation or usage of derivative works that
are not distributed. The GPL does not say that you cannot make derivative
works unless you GPL them.
So the restriction GPL_ONLY places is *not* a restriction that exists in
the GPL which is the *only* license. Hence it does not enforce a license
restriction. It really is that simple.
And when it comes to respecting the author's wishes, I respect the wishes
of the many people who contributed to the Linux kernel expecting the GPL to
ensure that usage remained unrestricted. I don't not respect the wishes of
the people who try to impose usage restrictions on other people's GPL'd code
and I thoroughly disrespect those who would wield the DMCA to restrict
modifications to code placed under the GPL.

If you read the ending part of Alan's message, you will see where
this fits into. Removing it, once again do not have any real
legal value while still within GPL 'usage boundaries'.
If the party that is accused of breaching GPL however did also
remove the GPL_ONLY symbols, it does once again have no legal
implication, except maybe enforcing a case of 'look, his intent
was from day one to breach GPL'. It is however not binding
legally, and its worth will depend on the country, legal system
and so on.

I do not see why point you want to make. If you do _NOT_ distribute
modified versions of the kernel, or works based on it, wtf worry ?
If you however do (hello, driver derived from kernel source/examples,
etc), you are bound by GPL (section 2a) to also distribute it under
GPL, and thus also the sources, which is exactly what manufactures
doing binary only drivers do not do.

Yes, didn't Alan just say it does not enforce anything?
What it does though do, what the whole idea behind it is, is if
party A, say do a binary driver, and they changed EXPORT_SYMBOL_GPL
to EXPORT_SYMBOL, then the kernel devs will _not_ support party A,
as Alan said with 'Its a hint and a support filter.'. Sure, you
are free to remove it, but if you do, do not expect any support.
The company I work for is a supplier of PC components. We have
the same type of support 'safety system' build in - we do not have
the infrastructure to support the public masses, thus we sell at
low prices to vendors that have a much higher markup, and good
support. If then somebody come to us, that is not a dealer, or
do not have an Invoice, sorry sir, go to who you bought it from.
Its basically the same thing if you think about it.
Can we now stop this, or could you continue this in private if
you still choose not to understand?

Are you saying that publishing a program does not constitute a "usage"
of the program and/or its source code?

No, I'm saying that publishing a program is not *just* a usage of the
program. You can have full usage rights to a program and not be able to
publish it because publication requires granting rights to other people,
which is not use.
Similarly, I can give you full rights to use my house but you still can't
sell my house. That's not because "selling" isn't a way of "using", it's
because selling is "using and then some". The additional thing that
distribution has that usage doesn't is the ability to grant rights to
others.
The GPL is quite clear on this point:
"Activities other than copying, distribution and modification are not
covered by this License; they are outside its scope. The act of
running the Program is not restricted, and the output from the Program
is covered only if its contents constitute a work based on the
Program (independent of having been made by running the Program).
Whether that is true depends on what the Program does."
When you distribute a copyrighted work, you are not just distributing the
physical work but you are also conveying at last some rights of usage to
other people. Conveying rights of usage is legally distinct from having
rights of usage.
Unrestricted use does not mean you can do whatever you please so long as it
somehow involves usage, it just means that the restrictions aren't upon the
usage itself. So anything that is *just* usage is okay. Anything that is
usage and something else is okay so long as the something else is okay. You
can have full unrestricted use of my bat and you still can't use it to beat
a stranger, but that's because you couldn't use anything to beat a stranger,
not because you don't have full use of the bat.
Distribution is usage and something else. The something else being the
conveying of usage rights to others. If you have unrestricted use, you can
still only distribute if you have the rights to the something else.
