[GNU-linux-libre] Freedom issues with non-free firmware in external files

2009-08-14 Thread Rubén Rodríguez Pérez
There is an ongoing discussion at the FSFLA and SolAR lists[1] to decide
if the ability of the linux kernel to request non-free firmware should
be removed or changed, if  the whole drivers should be deleted, or if it
is enough to remove the offending firmware files and discourage its use.

As this issue affects all distros, and the conversation was also
generating some complaints from the list administrators, I'd like to
start a new thread here.

I'll try to summarize the ideas in a neutral way:

-Linux includes some -GPL'd- modules that load firmware files into the
devices. Most of that files are non free, and most of them are required
to get the device working. All the free distros exclude that files.

-Older linux-libre versions -still in use in several distros- remove the
non-free blobs embedded in .c and .h files. External non free firmware
files are also deleted. Other cleaned linux versions work this way.

-Newest linux-libre versions remove not only the embedded blobs, but
also the ability of the modules to request non-free firmware files.[2]

The questions that came from that include:

-Is enough to remove the non-free firmware files from the distro and
discourage its use?

-Should GPL modules that are useless without the non-free firmware files
be removed?

-Should they be kept, but disabling the file load call?

-What is enough to comply with the Guidelines for Free System
Distributions? [3]

Note that this issue was already discussed in January by Richard
Stallman, Alexandre Oliva et. al. at the linux-libre lists[4], leading
Alexandre to implement one of the discussed solutions in the linux-libre
deblobber. Other solutions are possible, so this new thread should focus
on what is _enough_ to achieve a fully free kernel.

 or only print info about what is missing?

 The vanilla kernel prints an error about the missing files if the
 request fails. For the case of non-free blobs, linux-libre now prints
 a /*DEBLOBBED*/ message, and the files are not actually requested.

Ututo now also prints a special message.

 If a driver needs a non-free firmware file to work, removing it renders
 the driver useless, so you can remove it. Having non working drivers
 looks pointless to me, and can -maybe in a subtle way- cause harm.

could you tell us about this subtle harm?

 Then the maintainer of the freed version of the kernel can stop removing
 that module.

and the people will need to upgrade, a lot of additional work

 is there another way to detect that hardware?

 All hardware can be detected. That part doesn't matter.

can is different than doing it. Why do you think that do not matter

 is not usefull to know what hardware do not have frre software to work with?

 Yes, but how is that related to the load call thing?

is related to the module

modules are a way to know if the hardware exists and is working.

  -What is enough to comply with the Guidelines for Free System
  Distributions? [3]

 is this free guideline fine?

 Is ok for me, but maybe it needs some clarifications (like this issue).

its not weel organized, have a lot of confusing parts, etc

but the principal issue is its central argument

we have free software definition, a huge agreement about that, why try
to impose additional conditions?

why to speak about trademarks and  non functional non-free works

we are talking about a free distribution with non free material, why?
For example debian is more restrictive on that

 is free-linux something usefull? or the removal can be done by a
 script running over a normal kernel?

 I'm not sure if I'm getting your question. :|

do the world need free-linux?

we have free gnu/linux system without blobs a long time before that
project exists.


 do free distros must have non-free-software-having-hardware detection
 procedures and user warnings?

 Please, explain non-free-software-having-hardware detection procedures

capability to detect and warn user about hardware without free software

Nice. What does it say?

 could you tell us about this subtle harm?

E.g. someone can tell your users how to make the driver work, by
recommending to use the non-free file, thus harming their freedom. It's
not you who is causing the harm, but the one who recommends the file.
But if the driver is removed, you are not even allowing that to happen.

 
  Then the maintainer of the freed version of the kernel can stop removing
  that module.

How can you provide your users with a new driver without an upgrade?

 can is different than doing it. Why do you think that do not matter

I think you are using detecting in a different way than I do. The
kernel does not need the modules to know if a piece of hardware is
present. No matter if you remove the module, it can be detected.

 
  is not usefull to know what hardware do not have frre software to work 
  with?
 
  Yes, but how is that related to the load call thing?

You can't tell if -let's say- a ipw2100 card is broken unless you use
the non-free firmware. I wouldn't care if it's broken, it doesn't work
with free software anyway, so it is always broken.

I don't see the guidelines being imposed. I see them as an useful set of
recommendations -not everyone is aware of the issues of a free distro-,
and it can be useful for non-free distros that might like to go libre.

Additional positions should be taken every time a new threat appears.

 why to speak about trademarks and  non functional non-free works

 For example debian is more restrictive on that

Everyone has a viewpoint, that is why they are called guidelines, and
that is why I think we should talk about them.

Including non-modifiable art is ok to me. Trademarks and patents are
important issues that every distro needs to be aware of.

That is a rude question. If you don't like it, don't use it, it's not a
requirement. I mentioned it as an example implementation of a freed
kernel, and it is used by several projects in this list, so it makes the
task of cleaning more easy for a lot of hackers including myself.

I think it is a nice feature, that allows us to tell the user about the
perils of non-free software. I also think it shouldn't be mandatory.
