Hello everyone,
as you may have already heard I'm volunteering as release manager for the
upcoming glibc 2.38.
We follow approximately the same schedule as last time.
- July 6-11, "slushy ABI freeze"
* No new ABI additions.
* ABI corrections should be reviewed, RM approval not required.
* Avoid any changes that require action by the ports (including all
that require ulps regeneration)
* Bug fixes.
* Monday patch review switches to reviewing critical bug list and
ABI issues.
We still have two "desirables" on the wiki page,
* "Add clone3 support for multiple architectures" - can we wrap this up
safely next week?
https://patchwork.sourceware.org/project/glibc/list/?series=16730
* "Flip defaults for some security-relevant build configuration flags"
https://patchwork.sourceware.org/project/glibc/list/?series=21908
The series consists of 4 patches. 2 (stack-protector-strong), 3
(bind-now) and 4 (disable-crypt) should be uncontroversial.
## The list thread on 1 (autoconf-2.71) ended without a clear
conclusion. What's the status here? ##
Anything else?
- July 12-31, "hard ABI freeze"
* Noncritical bug fixes.
* No ABI changes without RM discussion.
* High risk bug fixes should be discussed on the list.
- August 1
* glibc 2.38 release
If you have any comments or objections, please reply to the list.
Cheers,
Andreas

May I add
https://patchwork.sourceware.org/project/glibc/list/?series=22006 here?
The reason:
- It's trivial.
- Applying it here will stop GCC analyzer developers from implementing
these as special cases.

I addressed Joseph's concern about sysdep configure and preconfigure
snippets in v2; I clarified in the git commit log that the sysdep
scripts did change but they were all trivial transformations that do not
affect functionality.

The missing patches are for s390x, arm, and mips. I think it should be ok
to push them, I have test all on them on hardware (s390x) and qemu system
(s390x and mips).
It would be good to have the pidfd and cgroupv2 extension as well [1], since
systemd is asking for such interface for some time.

That's clone3, I guess you mean this one?

"Checked on mips64el-linux-gnueabihf and mipsel-linux-gnu."
How about N32 ABI (where things like to explode)?

OK from me
1) please get it technically reviewed from someone as usual (should be a
formality only in this case)
2) question, should we add v3 (safer but less functional) now and update
it to v4 (stricter but more functional) in master after release?

That's a performance fix and also rather complex code.
I'd prefer to defer this to after the release; it looks to me like it could
be backported after more testing.

Apart from this ^, looks OK to me.
Would be good to get an Ack from someone familiar with the ports still though.

If you're talking about this one ^, "Add pidfd and cgroupv2 support for process
creation (resend)", this is in my opinion too much code too late.
I realize this is desirable, so let's add it to master as soon after the release
as possible.

Dear Andreas,
I feared that answer. It was a very similar reason why it was not in 2.37.
It is really a pity that nobody takes the time to look at this patch.

I hope it can be done in the next Monday review... It seems v2 (same as
v3 but lacking a S-o-b) has already been reviewed as OK.

And testing on mips64el-n32 it triggered a failure not really related to n32
(it was a wrong name for the SETUP_GP64_STACK macro). I will send an update
version for mips.

I would like to make sure any necessary follow ups for tuning the
`non_temporal_threshold` on X86 machines gets into 2.38.

Let's be careful and reluctant with pure performance tuning.
Bug fixes are of course fine (and yes I know the boundary is somewhat
ill-defined).

I think this one is more in the former category. At the very least want
to add a bound that ensure new number is never less than older value
(to avoid any blatant regressions). But hoping to hear from Sajan before
then to see if we can get a proper fix in.
