weak implementation of threads has problems - kse fix attached

From: Sean McNeil <sean_at_mcneil.com>
Date: Mon, 07 Jun 2004 19:57:35 -0700
Up front, I'd like to make a few apologies:

1) I am sorry for the length of this email.
2) Although some very valid opinions have been expressed, I respectfully
have to disagree.  This email will hopefully strengthen my position.

The problem:

(If you just want kse threads to work for you properly, just apply the
patch at the end of this email and try it out).

kse threads on amd64 doesn't work with gnome.  It crashes applications
here and there.  gnome-terminal is essentially unusable.

I strongly believe this to be a binding issue.  I've examined rtld and
I'm satisfied that it is behaving appropriately, so I took a long hard
look at how FreeBSD has implemented the pthread interface, how it is
being used, and how people expect it to behave.

FreeBSD pthread interface:

I have no idea why, but on FreeBSD all the pthread functions are weak
symbols.  I have not beed given a very satisfactory answer though I have
tried to understand and continue to look for enlightenment.

To me, this means that there is no authorative answer to "who is the
primary provider" of the weak symbols in libc.  It is instead the first
occurrence of the weak symbol that takes precedence.  This means that if
the program itself doesn't link with the pthread library yet some other
library uses it then you are pretty much hosed.  I've seen just this
happen with plenty of gnome applications.  It also means that there is
an ordering dependency that I'm not sure is reasonable to enforce.

Other pthread interfaces:

I don't know what Linux does now, but when we first built pthreads for
Linux we made the pthread library symbols definitive.  They always were
the overriding authority.  It was modelled after what I saw in Solaris. 
So, taking select as an example,

libc.so - internal select called something else with a weak reference to
used symbol.
libpthread.so - select essentially provided directly in the library or
is a strong reference to an internal version.

i.e. libc weak, libpthread strong.

This allows for any ordering of libraries during linking.  Very good
(IMHO) and has other benifits as well - like security.

Application issues:

As mentioned above, gnome is not very usable as things stand.  I had to
move to libc_r to get any stability at all.  Besides gnome, I have found
issues with apache2/php4, wine, and bash with nss_ldap to name a few.

Security:

Actually, having an authorative provider of core libc functions would be
very helpful to eliminating a potential security risk.  An application
that is linked with libpthread wouldn't be able to dlopen some other
library that could potentially take over libc weak functionality. 
Additionally, some sort of non-threaded library could be created that
blocked a program from overriding libc routines with thread versions
whenever it was linked directly to the main application.

Proof is in the pudding:

What can I say?  Some people will insist that the gnome applications are
broken somehow or that what I'm saying doesn't conform to their view as
how the thread libraries should work.  I admit I do not fully understand
the dogma behind making them all weak symbols, but so far nothing I've
heard trumps the fact that doing this makes everything work.  Since
applying the patch below, my amd64 system has worked flawlessly with
gnome and libpthread.so.1.  It has not shown any of the problems that
have been haunting me since I switched over from running in i386 mode.

The patch:

A patch to apply in /usr/src/lib/libpthread is included at the end of
this email.  I haven't bothered doing it for libc_r even though it
should be done.  Apache2/php4 would have issues, for instance, with
libc_r without making the symbols strong references.

Anyone else that wants to use gnome right now under amd64 might want to
try out this patch.

Cheers,
Sean
