A whole lot has changed since `sln` was introduced into glibc upstream with
this comment:
```

* elf/sln.c: New file.

Among other things for example, dynamic linking has been in use for the nearly
20 years that have passed and is now quite reliable. Further, many Fedora
systems now use an initramfs (dracut) which is basically a large filesystem of
utilities as a single blob; while it would require rebooting, one can easily
make hardlinks there.
Futher of course there's the increasing use of ostree in Fedora which which
consistently captures *all* of userspace and supports rollback, and additionaly
its presents a "read only" nature to admin tools and other processes that adds
significantly to system resilience.
The failure scenarios that could be recovered via `sln` seem to me to be very
small.
Applying this patch allows dropping a downstream Fedora patch to hardlink `sln` to `ldconfig`,
which was the source of a tricky bug:
https://github.com/projectatomic/rpm-ostree/pull/1173#issuecomment-355014583
that also impacts rpm-ostree. In practice today SELinux policy is fixed
in updates, but given there's no real reason for this binary to exist
anymore, let's drop it.

malloc: Avoid optimizer warning with GCC 7 and -O3
The Perl Info generator in Texinfo 5.0 uses the input basename in the
output file, so the multi-arch conflict no longer happens, and the
Makefile tweak is not needed anymore.
This commit drops an overridden -fasynchronous-unwind-tables flag, which
had no effect.
We compile all of glibc with -fno-asynchronous-unwind-tables, so we can
drop glibc-fedora-ppc-unwind.patch.

(#1476839)
Using eval affects command line parsing in the shell script. Call the
script directly, but do not quote $find_debuginfo_args, to splice its
contents into the argument list.
This works around an RPM change in the processing of macro argument lists.
Newer RPM versions split the argument list, so that %1 contains just eo,
and not the whole language list.
Instead, use %language_list directly. This is compatible with earlier
RPM versions, too.

The glibc rawhide builds must stay on 2.25 branch until
F26 branches from rawhide. This assures that we have ABI/API
guarantees provided by upstream. Please do not rebase rawhide
against glibc master.
Provide libcrypt and libcrypt-nss subpackages.
glibc has a Recommends: to prefer the NSS-based implementation.
glibc-devel requires that one of the two packages is installed.
Move NSS modules to subpackages
Add new file lists for the NSS modules and update the glibc and
glibc-devel file lists. Introduce a glibc-nss-devel package
for direct linking against NSS modules (which is rare and usually
unintended). Drop the obsoletes clause for nss_db.
We prefer scriptlet expansion (-e) over the use of rpm.expand in Lua.
The goal is to have a fully expanded Lua program with as little
dynamic processing as possible to simplify the operations carried
out in Lua.
The use of rpm.expand was only needed until COPR migrated from EL6
to Fedora, and with this complete we can remove the use of rpm.expand
in favour of scriptlet expansion.
Tested on Fedora Rawhide by verifying global setting of %_install_langs
macro changes installed locale-archive locales correctly.
Revert fix for “Preloading a replacement uname is causing environment

First phase of sendmsg/recvmsg/sendmmsg/recvmmsg ABI revert:
GLIBC_2.24 compatibility symbols.
This should allow us to run old binaries (with the GLIBC_2.24 symbols)
while rebuild packages to use the old ABI again.
Drop glibc-nsswitch-Add-group-merging-support.patch, applied upstream.
Drop glibc-rh1252570.patch, alternative fixes applied upstream.
Adjust glibc-rh1315108.patch to minor upstream change.
Update SUPPORTED file.
Locales, translations, and locale sources are split into
distinct sub-packages. A meta-package is created for users
to install all languages. Transparent installation support
is provided via dnf langpacks.
This update brings 64-bit POWER support in line with
other distributions and removes the 32-bit POWER support.
We specify clearly exactly what we support for BE and LE
64-bit POWER.
- The generic hidden directive support is already used for
preinit/init/fini-array symbols so we drop the Fedora-specific
patch that does the same thing.

Create a new package glibc-benchtests with the benchmark binaries that
one may download and run to benchmark glibc for their machine. More
importantly, the glibc-bench-compare and bench.mk scripts can run
benchmarks and compare performance of two arbitrary glibc versions as
long as both versions have the glibc-benchtests package.
Usage:
Scenario 1: Compare two build numbers, e.g.:
/usr/libexec/glibc-benchtests/glibc-bench-compare 2.20-1.fc21 2.21.90-11.fc22
If a second build is omitted, comparison is done with the currently
installed glibc.
Scenario 2: Compare two downloaded rpms - only glibc, glibc-benchtests
and glibc-common are needed for both versions. e.g.:
/usr/libexec/glibc-benchtests/glibc-bench-compare -p <dir1> <dir2>
Fix up a Fedora patch to pass the address of the mutex in the mstate
instead of the mstate itself. This fizes the Werror warning seen on
all non-x86 builds.
- Disable lock elision support for Intel hardware until microcode
updates can be done in early bootup (#1146967).
- Fix building test tst-strtod-round for ARM.
There was no rationale given for the change to fix bz#737223 and the
fix was never even proposed upstream. This patch causes a test
failure in the glibc testsuite. Revert the patch for now and do a
proper documented analysis if this actually results in any kind of
failure.
build-locale-archive was switched to link dynamically in 538b3c08
without giving a proper reason for it. The earlier static build was
wrong though, since it would happen against the installed glibc and
not the glibc being built. The dynamic link was also similarly wrong,
more so because it would build against the built libc.so.6 and then
try to load the system libc.so.6. This results in a failure in %post
in cases when the new build-locale-archive may have symbol references
that are not present in the old glibc.
There seem to be no good reason to run build-locale-archive with the
system libc.so.6, so the change is now reverted with a fixed up static
link that links against the build static libc.a.
- Allow up to 32 dlopened modules to use static TLS (#1124987).
- Run glibc tests in %%check section of RPM spec file.
- Do not run tests with `-k` and fail if any test fails to build.
in order to work around GCC reordering compares across the TLS
descriptor sequence (GCC PR61545.) Committing a (temporary) fix here
allows us to avoid rebuilding the world with gcc 4.9.0-11.fc21.
Following commit upstream removed the definition for elfobjdir in
favour of elf-objpfx. Adjust rtkaio to build with this.
commit 4134b50d6789c333707b1861a32314805bd0de5e
Author: Joseph Myers <joseph@codesourcery.com>
Date: Wed May 21 16:52:08 2014 +0000
Consistently use $(elf-objpfx).
As previously noted
<https://sourceware.org/ml/libc-alpha/2013-05/msg00696.html>,
$(elf-objpfx) and $(elfobjdir) are redundant and should be
consolidated. This patch consolidates on $(elf-objpfx) (for
consistency with $(csu-objpfx)), also changing direct uses of
$(common-objpfx)elf/ to use $(elf-objpfx).
After each test run we output all of the test results
to the build logs. This includes PASS, FAIL, XPASS,
XFAIL results and the original error codes of the tests.
Without this fix the new upstream PASS/FAIL support
hides the test results from the build logs.
Currently the nscd service is installed in systemd as a simple
service, which means that it is able to handle its own errors and does
not quit. Since nscd does not fit that description, i.e. it can exit
on errors like, say, failing to parse nscd.conf, it should be declared
as forking instead.
The call to open_tmpl_archive was being passed a pointer to an
object allocated on the stack. The object on the stack is not
guaranteed to be initialized to zero so we need to minimally
initialize `fname' in the struct locarhandle to ensure that
open_tml_archive loads the default tempalte.
This error was seen while debugging glibc installs in a qemu
VM where it is more likely the stack pages were dirty. It has
not been reported on non-VM systems.
- Allow applications to use pthread_atfork without explicitly
requiring libpthread.so. (#1013801)
- Support `--list-archive FILE' in localedef utility.
- Allow ldconfig cached objects previously marked as hard or soft
ABI to now become unmarked without raising an error. This works
around a binutils bug that caused objects to become unmarked.
(#1009145)
This patch fixes the spec file to use %{_prefix} everywhere that
is related to the package and subpackages. However, external
utilities are still referenced by their absolute path which
includes /usr.
The `Move to /usr' transition for glibc can not be completed
without support from RPM. There are too many Requires that
explicitly reference non-/usr paths in various spec files.
Reverting this patch is the only way forward until we find
a transitional way to support this.
All relevant files are not installed to /usr, with the expectation
that the distribution will provide compatibility links from the
old paths to the new paths. All uses of a bare `/usr' have been
replaced with uses of `%{_prefix}' for files installed by the
