Emergency patch from libc-alpha.
From: Siddhesh Poyarekar <siddhesh@sourceware.org>
Subject: [PATCH v2] iconvconfig: Fix multiple issues
To: libc-alpha@sourceware.org
Cc: schwab@linux-m68k.org, fweimer@redhat.com
Date: Fri, 25 Jun 2021 14:31:28 +0530
Message-Id: <20210625090128.316837-1-siddhesh@sourceware.org>
It was noticed on big-endian systems that msgfmt would fail with the
following error:
msgfmt: gconv_builtin.c:70: __gconv_get_builtin_trans: Assertion `cnt < sizeof (map) / sizeof (map[0])' failed.
Aborted (core dumped)
This is only seen on installed systems because it was due to a
corrupted gconv-modules.cache. iconvconfig had the following issues
(it was specifically freeing fulldir that caused this issue, but other
cleanups are also needed) that this patch fixes.
- Add prefix only if dir starts with '/'
- Use asprintf instead of mempcpy so that the directory string is NULL
terminated
- Make a copy of the directory reference in new_module so that fulldir
can be freed within the same scope in handle_dir.

# Auto-generating dependencies for glibc development snapshots.
#
# A glibc development snapshot (say version 2.33.9000) may define
# symbols in its under-development symbol version (GLIBC_2.34). RPM
# automatically derives RPM dependencies such as
# libc.so.6(GLIBC_2.34)(64bit) from that. While the GLIBC_2.34
# version is under development, these dependencies may be inaccurate
# and could be satisfied by glibc RPM package versions that lack the
# symbols because they were created from an earlier development
# snapshot that had some other GLIBC_2.34 symbols. Therefore, if the
# latest, under-development ELF symbol version is detected, this
# dependency generator adds an explicit RPM dependencies on the glibc
# packaging version against which an RPM package is built.
#
# This script runs for the glibc build itself. In this case, it may
# produce a >= dependency on the build-time glibc, but there will also
# be an (potentially indirect) = dependency, which takes precedence.
