Linux 2.4.34-pre2

[Willy Tarreau <wtarreau@hera.kernel.org>]

Hi !

This is Linux 2.4.34-pre2. It fixes several security issues which are
already solved in -stable. It also adds a few cleanups and minor fixes. 
Issues have calmed down, I believe it was the right moment to tag it.

Everything should build without trouble. After discussing the pros and
cons of merging Mikael Petterson's portability fixes to support gcc4, it
looks like people still using 2.4 were interested in this merge, while
those who had already fully moved to 2.6 expressed mixed opinions. The
fixes to support gcc 4 are mostly either obvious or pending bugs waiting
for some victim. Right now, the fixed tree is known to build with gcc 4.1
and run on the following architectures :

  i386 (UP/SMP), x86_64 (UP/SMP), PPC, sparc64 (UP/SMP)

Additionally, sparc is known to at least build, but possibly not all
drivers yet since it's harder to produce all config combinations.

The goal for 2.4.34-pre3 will be to merge those fixes and try to catch
the last remaining build errors if any. Since GCC4 also produces lots
of very interesting warnings, I'm interested in patches to silent them
(real fixes, not erroneous type casts to hide bugs). Patches to fix
other archs will be welcome (one patch per error with the capture of
the error in the commit please), and after a few pre-releases, the
gcc version check will be restored to prevent accidental build of
unsupported archs.

Also, keep in mind that we're still in preview versions. There are about
70 one-liner fixes, and I'm not going to run after every maintainer to
ask them for individual confirmation for mostly obvious fixes. If some
maintainer want to review some patches before the merge, please raise
your hand. Everything is available here anyway :

  http://www.kernel.org/git/?p=linux/kernel/git/wtarreau/linux-2.4-gcc4.git;a=summary 

During this time, 2.4.33-stable will still provide fixes, of course, so
even if in the extreme case, we broke a few pre-releases, it would not
be a problem at all.

Best regards,
Willy
