bug#22831: OpenSSL should not depend on Perl

[Ludovic Courtès]

Commit 784d6e91 changed OpenSSL such that it does not depend on Perl,
but one of the subsequent upgrades broke it:

--8<---------------cut here---------------start------------->8---
$ guix build perl
/gnu/store/x2p2biyybcb2wac77qz9468asc5fm48i-perl-5.22.1
$ grep -r x2p2biyybcb2wac77qz9468asc5fm48i $(guix build openssl)

--8<---------------cut here---------------end--------------->8---

Somehow ‘openssl-c-rehash.patch’ seems to no longer have the desired
effect.

Bisecting, I narrowed it down to:
86c8f1daf8ed10f13f2b1e973a28845629b8ce47
(gnu: openssl: Update to 1.0.2e [fixes CVE-2015-{3193,3194,3195}].).

I'll get the openssl sources corresponding to the good and bad commmits
and try to figure out what changed that pulled perl back in.

Awesome.  Hopefully we can apply the fix when we upgrade OpenSSL this
Tuesday.

Thanks,

Also we should add something like:

  #:allowed-references (list (canonical-package glibc)
                             (list (canonical-package gcc) "lib")
                             "out")

to avoid regressions.

(A case where #:disallowed-references would be more convenient, but it’s
not yet implemented.  :-))

'openssl-c-rehash.patch' is being applied, but at some point in the
build process the change is reverted.

I haven't figured out why yet. Ludo is right, it would be really good to
only change our OpenSSL package one day this week.

So, I'm asking for help with this problem!

I will spend some time on it tomorrow, but I really don't have any
promising leads. My plan is to step through the build process and learn
when the shebang is recreated. Hopefully then I will get some
inspiration.

I suppose a nasty short term fix would be to patch the file after
installing it. I will submit that patch if it seems there is no other
option in time for the security update.

bug#22831: [PATCH 0/2] OpenSSL / Perl run-time dependency

[Leo Famulari]

Patch 1/2 updates the patch we use to keep Perl from becoming a
registered run-time dependency of OpenSSL.

Patch 2/2 is an attempt to use #:allowed-references to prevent
Perl from sneaking back in again. Unfortunately, it fails when gcc is an
allowed reference. It "works" when gcc is not in the list. Here's the
backtrace:

I realized that it would work if I imported (gnu packages gcc) when
defining the tls module. I don't know if that's the right approach or
not, but the output now refers only to glibc, gcc:lib, and itself.

In the source, I see:

--8<---------------cut here---------------start------------->8---
$ find -name c_rehash\*
./tools/c_rehash
./tools/c_rehash.in
./doc/apps/c_rehash.pod
--8<---------------cut here---------------end--------------->8---

Could it be that the unpatched one ends up being installed or something?

Indeed.  Fixed in caeadfd, though without #:allowed-references—it’ll be
more convenient to use #:disallowed-references when it’s implemented.

For some reason I hadn’t seen it in M-x debbugs-gnu for this report
today, but the patch looks good to me!

If we apply it now, it won’t trigger a rebuild (yay!), but will still
trigger a bunch of regrafting, which is slightly annoying.  What about
applying it in the next ‘security-updates’ branch?

Thanks!

Since there was already a security-updates job started, how about
