Subject: glibc fails to build on i686
Date: Sun, 25 Jun 2017 21:19:48 +0200

Since commit 665d6a59161769e10b52ffcbcd5cd2db22f32681 I have to build
glibc from source.  Unfortunately, this fails with the following error:

This means I cannot upgrade my i686 machines.

Hmm.  The patches added by commit 665d6a5916 change only one file:
rtld.c, so I don't see how that could affect the building of
strcspn-c.c.

For now, I will try to build this derivation on Hydra, so that it will
be available as a substitute.

The same failure occurred when Hydra tried to build this.  I'm not sure
what's going on here.  To be continued...

I built both the grafted and ungrafted versions of 'glibc-final' for
i686-linux, and compared the build logs.

The problem is that glibc-CVE-2017-1000366-pt2.patch introduces a
reference to 'strcspn' in rtld.c.  This causes the glibc build system to
automatically add 'rtld-strcspn.os' and 'rtld-strcspn-c.os' to the list
of objects to be built.  When 'rtld-strcspn-c.os' is built, "-msse4" is
passed to the compiler (along with "-mno-sse" near the end).

Here's are the relevant parts of the diff:

I found a patch in Debian to address this issue:

With this patch added, the grafted glibc builds successfully on i686.
I'm doing a few more tests, and then will push this in the next hour or
two.

I believe this problem is fixed by commit
ffc015bea26f24d862e7e877d907fbe1ab9a9967.  I was able to build a grafted
'hello' for i686-linux, and it worked correctly.

Can you try it and report back?

NOTE: This message isn't meant to sound aggressive, it's just a question
from a novice Guix user.

Here is my situation:

- I'm using Guix in a foreign distribution (Trisquel 7).

- In 2017-06-12, I pulled and upgraded Guix and packages successfully as
  root.

- Last weekend I did (all as root): `guix gc` (successful), `guix pull`
  (successful), `guix package -u guix` (not successful, because of this
  bug).

- Some time has passed, and the core-updates branch now seems to have a
  fix for this bug.

- Yesterday (or was it the day before it?), I did (all as root): `guix
  gc` (successful), `guix pull` (not successfull, because of this bug),
  `guix gc`, `guix pull
  --url="https://git.savannah.gnu.org/cgit/guix.git/snapshot/guix-ed068b960eeedb92823238783779730319b8ba0e.tar.gz"`
  (not successful, because of this bug). Notice that in the last pull I
  used the snapshot corresponding to the merge in core-updates that has
  the fix.

Now, I'm thinking, how can I make the pull and the Guix package upgrade?

I'm sorry you experienced this bug. We didn't test the change to glibc
on i686-linux so we didn't notice this problem until after we pushed it.

As announced earlier in this bug discussion, the bug was fixed on the
master branch with commit ffc015bea26f24d862e7e877d907fbe1ab9a9967.

I recommend you try again, but on the master branch. Core-updates is not
currently usable (hopefully soon!).

It might be that you need to manually remove the ~/.config/guix/latest
symlink in root's home directory, and then run "guix pull" again.
Normally this is not needed, but in this case it might be needed to
recover from your current state.

As an aside: I'm not sure why you're running these commands as root.
Running "guix pull" as a user FOO effectively updates the package list
for user FOO, and not for any other user.  Running it as root is no
exception to this rule.  Each user, including root, has their own
private package list.

The main reason to run these commands as root is if you want to update
the packages in ~root/.guix-profile, or if you want to update a GuixSD
system.  Normally, each user runs these commands, including "guix pull"
under their own account.

As Leo said, unless you want to help us debug problems on core-updates,
it's best stick with 'master' for now.  'master' is the only branch that
receives timely security updates.  'core-updates' is a work-in-progress,
and at present there are many broken packages there.

Removing the "~/.config/guix/latest" symbolic link as was suggested by
Mx. Weaver worked, now my root user can pull and also upgrade the "guix"
package. Thank you all for the suggestion. :)

Besides, as was also suggested: I'll use the "master" branch instead.

I'm glad to hear that it solved your problem.  I'll close this bug now.
