Change the default build configuration to use the latest autotools
(released in 2021) and to harden the default build.  These options are
used by most distributions, making them more relevant.

Siddhesh Poyarekar (4):
  configure: Use autoconf 2.71
  configure: Default --enable-stack-protector to strong
  Disable lazy binding by default
  configure: Disable building libcrypt by default

Bump autoconf requirement to 2.71 to allow regenerating configure.ac on
more recent distributions.  autoconf 2.71 has been in Fedora since F36
and is the current version in Debian stable (bookworm).  It appears to
be current in Gentoo as well.

Did you regenerate all the subdirectory configure / preconfigure fragments 
(i.e. autoconf $file.ac > $file, for $file in all the configure and 
preconfigure files in sysdeps that have a corresponding .ac file - note 
that many preconfigure fragments are just shell script fragments with no 
corresponding .ac file) and find that they didn't change?

Ahh no I didn't because we rarely change them.  I'll do this.

Actually, before I do this, the files are most likely going to change 
because autoconf 2.71 gets rid of the (AFAICT Solaris-specific) hack 
$as_echo and some other stuff, so there's a bunch of non-interesting 
changes.  May I assume we want to make these changes anyway since we 
specifically mention 2.71 as the supported autoconf?

Thanks,
Sid

My assumption is that changes from regeneration are desired - *but* if 
those changes result in extra function definitions appearing in those 
fragments, and those functions are actually defined in configure before 
the fragments are read, then the GLIBC_PROVIDES definition in aclocal.m4 
may need updating.  (It's possible there are existing function definitions 
in some of the fragments that should actually be dealt with that way as 
well.)

If anything autoconf 2.71 does seems undesirable in the context of glibc (whether preconfigure or otherwise), or just plain doesn't make sense, don't hesitate to ask me about it.

All major distributions use this level of stack protector, so make it
the default.

Lazy binding is a key security feature and is enabled by all major
distributions by default.  Default to this more secure option and flip
the flag to allow disabling it if needed.

This seems backwards. "Lazy binding prevents some key security features and
is disabled by all major distributions by default"? Or something like that?

Yeah I got the git commit description wrong; I meant to write "bind-now 
is a key security feature", but I like your version better.  Thanks, 
fixed my commit log.

We mentioned eventual dropping of libcrypt in the 2.28 NEWS.  Actually
put that plan in motion by first disabling building libcrypt by default.
In the near future we need to drop it completely but ISTM that Gentoo
still uses it to fix some perl compatibility issues.

Thanks. This is fine for us: we did the migration in two stages in
Mid-to-late 2021.

You are right that we've got a workaround for some Perl rebuild issues,
but that should've been fixed on our end in the package manager last
month, so no problem from us. Thank you for checking!

I feel like we ought to explicitly name libxcrypt as a possible
provider - I don't really like relying on word of mouth for this.

We don't need to endorse it/recommend it (although what's the
alternative?), but I think mentioning it is worthwhile.

(ditto for texi change.)

"build and install the deprecated ..." (legacy is fine too, if you like)

Should we put a date on it, i.e. say explicitly that it will be removed 
in 2.39?

Thanks,

Change the default build configuration to use the latest autotools
(released in 2021) and to harden the default build.  These options are
used by most distributions, making them more relevant.

Changes from v1:

- Regenerated sysdeps configure and preconfigure fragments and verified
  that all changes are trivial transformations, e.g. from $as_echo to
  printf, replacing "main ()" with "main (void)", etc.  Based on
  Joseph's feedback.

- Fixed commit message in 3/4 based on Michael's feedback.

- Fixed text in 4/4 based on Dmitry's feedback

Siddhesh Poyarekar (4):
  configure: Use autoconf 2.71
  configure: Default --enable-stack-protector to strong
  configure: Disable lazy binding by default
  configure: Disable building libcrypt by default

Bump autoconf requirement to 2.71 to allow regenerating configure on
more recent distributions.  autoconf 2.71 has been in Fedora since F36
and is the current version in Debian stable (bookworm).  It appears to
be current in Gentoo as well.

All sysdeps configure and preconfigure scripts have also been
regenerated; all changes are trivial transformations that do not affect
functionality.

  To: libc-alpha; +Cc: Andreas K . Huettel, Carlos O'Donell

Bump autoconf requirement to 2.71 to allow regenerating configure on
more recent distributions.  autoconf 2.71 has been in Fedora since F36
and is the current version in Debian stable (bookworm).  It appears to
be current in Gentoo as well.

All sysdeps configure and preconfigure scripts have also been
regenerated; all changes are trivial transformations that do not affect
functionality.

Change from v2:

Resolved conflicts in ./configure and sysdeps/loongarch/configure.  I'll
push this once `make check` finishes.

I've pushed this now.  As discussed in the patch review call today, let 
me try and turn the remaining patches around as soon as I can.  If I can 
do it soon enough we could add them to 2.38, or else skip over and add 
to 2.39.

All major distributions use this level of stack protector, so make it
the default.

I think if strong is the default (correct IMHO), it should be the
default for --enable-stack-protector, too.  I'm not sure if we need to
support legacy -fstack-protector at all, but we do, we'd need a separate
option argument.

I would expect some build-many-glibcs.py updates for this one, too.

But I think for this one, --disable-stack-protector actually works.

Thanks,
Florian

There's also --enable-stack-protector=full, which enables 
-fstack-protector-full, which is why I kept it as --enable-* rather than 
flipping it to --disable.

If we want to drop everything except strong, then IMO it doesn't make 
sense to add an addition configure option to enable the options that we 
dropped; it kinda defeats the whole point of the exercise.  If we want 
to retain them, then how about 
--enable-stack-protector={strong,full,legacy,no} with the default as strong?

I'm not going to push to resolve this during the freeze but we could 
work towards consensus.

Thanks,
Sid

Do you mean =all?

I don't think we really need anything but strong; -all is occasionally
interesting for correctness checking, though.  With -strong we might
miss cases where we did not systematically exclude some code because of
ordering dependencies because the compilers we tested with removed the
instrumentation as part of optimization.

My main point was that --enable-stack-protector should enable the
default (-strong), otherwise it's confusing.

Thanks,
Florian

OK, so  --enable-stack-protector={strong,all,no} with the default as 
strong, thus dropping -fstack-protector?

Or perhaps --enable-stack-protector=plain for the legacy
-fstack-protector setting.

Lazy binding prevents some key security features and is disabled by all
major distributions by default.  Default to this more secure option and
flip the flag to allow disabling it if needed.

This description is not correct because as far as I can see,
--disable-bind-now does not enable lazy binding if the toolchain or the
build flags default to it.

I think we should remove this flag, rather than making
--disable-bind-now work as documented.

Thanks,
Florian

I feel like this needs more thought either way then, no point blocking 
2.38 for it.  What's the use case for lazy binding?  Are people actually 
using this in the wild and would we be breaking things for them?

Thanks,
Sid

I don't think it matters.  We have very few symbols that can be bound
lazily.  Most symbolic bindings are against data symbols, which cannot
be bound lazily, so the performance win for glibc itself is minuscule.

I think it may have been beneficial before we had the libc_hidden
mechanism.  I suppose libpthread integration also helped to decreasing
binding overhead.

Thanks,
Florian

Fair enough, I'll respin this by dropping the option and let Andreas 
decide if it's suitable for 2.38.  If not, I'll just queue it up for 2.39.

We mentioned eventual dropping of libcrypt in the 2.28 NEWS.  Actually
put that plan in motion by first disabling building libcrypt by default.
In the near future we need to drop it completely but ISTM that Gentoo
still uses it to fix some perl compatibility issues.

This needs some build-many-glibcs.py updates.  I think we should
re-enable libcrypt on the sparc targets (it has custom hash
implementations) and at least another target, so that all code we can
build is actually built somewhere.

Thanks,
Florian

The following paragraph in INSTALL concerning --disable-crypt should
also be updated, since the patch makes it disabled by default.
Perhaps this should instead clarify who might need to enable it.

We mentioned eventual dropping of libcrypt in the 2.28 NEWS.  Actually
put that plan in motion by first disabling building libcrypt by default.
note in NEWS that the library will be dropped completely in a future
release.

Also add a couple of builds into build-many-glibcs.py.

The last sentence needs to be restructured so that it doesn't start with
