[BZ #10871]
* localedata/locales/ru_RU (mon): Rename to...
(alt_mon): This.
(abmon): Rename to...
(ab_alt_mon): This.
(mon): Import from CLDR (genitive case).
(abmon): Copy from the old content except the 5th month which is
now in the genitive case, even when abbreviated.
* localedata/locales/ru_UA: Likewise.
* time/tst-strptime.c (day_tests): Add an actual example of
a difference between %b and %Ob in Russian.
* sysdeps/mach/hurd/net/ethernet.h: Include <stdint.h>.
* sysdeps/mach/hurd/net/if_arp.h: Include <stdint.h>.
* sysdeps/mach/hurd/net/if_ppp.h: Do not include non-existing
<net/ppp_defs.h>.
_POSIX_CHOWN_RESTRICTED and _POSIX_NO_TRUNC should be always defined.
* sysdeps/mach/hurd/bits/posix_opt.h (_POSIX_CHOWN_RESTRICTED,
_POSIX_NO_TRUNC): Define to 0.
400669754d ('hurd: Fix nscd build') had the side effect of making
libc's freeaddrinfo expose freeifaddrs through __check_pf. We can just
move the renames to gai.c itself, along others.
* sysdeps/mach/hurd/check_pf.c (__getifaddrs, __freeifaddrs): Do not
define macros.
* nscd/gai.c (__getifaddrs): Define macro to getifaddrs.
(__freeifaddrs): Define macro to freeifaddrs.
* hurd/hurd.h (__hurd_fail): Always declare function, and provide inline
version only if __USE_EXTERN_INLINES is defined.
* hurd/hurd/fd.h (_hurd_fd_error_signal, _hurd_fd_error, __hurd_dfail,
__hurd_sockfail): Likewise.
(_hurd_fd_get): Always declare functions, and provide inline versions
only if __USE_EXTERN_INLINES and _LIBC are defined and IS_IN(libc).
* hurd/hurd/port.h (_hurd_port_init, _hurd_port_locked_get,
_hurd_port_get, _hurd_port_free, _hurd_port_locked_set,
_hurd_port_set): Always declare functions, and provide inline versions
only if __USE_EXTERN_INLINES and _LIBC are defined and
IS_IN(libc).
* hurd/hurd/signal.h (_hurd_self_sigstate, _hurd_critical_section_lock,
_hurd_critical_section_unlock): Likewise.

_hurd_fd_error, __hurd_dfail, __hurd_sockfail, _hurd_port_locked_set,
__hurd_threadvar_location_from_sp, __hurd_threadvar_location,
_hurd_userlink_link, _hurd_userlink_unlink, _hurd_userlink_clear.
Some warnings need a couple of fixes in the gnumach headers.
* scripts/build-many-glibcs.py (checkout_vcs): Add gnumach
repository URLs, run autoreconf, and make it the default for now.
* sysdeps/mach/hurd/getresgid.c (__getresgid): Set result from
critical section to make code simpler and avoid warning.
* sysdeps/mach/hurd/getresuid.c (__getresuid): Set result from
critical section to make code simpler and avoid warning.
Making `special_profil_failure' both avoids warning "variable
'special_profil_failure' set but not used", and makes it easier to
access with gdb.
* sysdeps/mach/hurd/profil.c (special_profil_failure): Move variable
to global scope.
Some warnings come from code generated by mig, so we need a very recent
version for now.
* scripts/build-many-glibcs.py (checkout_vcs): Add mig repository
URL, and run autoreconf, make it the default for now.
This was dropped from GNU Mach in 2006.
* mach/Machrules (MIGFLAGS): Do not set -DMACH_IPC_COMPAT=0.
* mach/mach/mach_traps.h: Drop comment about MACH_IPC_COMPAT.
* sysdeps/mach/hurd/fork.c (__fork): Drop special casing
MACH_IPC_COMPAT.
gcc's libcilkrts has never actually supported GNU/Hurd, and doesn't
automatically disable it, and the support was actually removed in gcc trunk,
so that will never actually be fixed there.
* scripts/build-many-glibcs.py [os == gnu] (build_gcc): Pass
--disable-libcilkrts to gcc configure.
timer_ptr2id and timer_id2ptr are used to convert between
application-visible timer_t and struct timer_node *. timer_ptr2id was made
to use void * instead of timer_t in 49b650430e ('Update.') for no reason.
It happens that on Linux timer_t is void *, so both that change and this
commit are no-ops there, but not on systems where timer_t is not void *.
Using timer_ptr2id for filling sival_ptr also does not make sense since that
actually is a void *.
* sysdeps/pthread/posix-timer.h (timer_ptr2id): Cast to timer_t
instead of void *.
* sysdeps/pthread/timer_create.c (timer_create): Do not use
timer_ptr2id to cast struct timer_node * to void *.
In commit cba595c350 and commit
f81ddabffd, ABI compatibility with
applications was broken by increasing the size of the on-stack
allocated __pthread_unwind_buf_t beyond the oringal size.
Applications only have the origianl space available for
__pthread_unwind_register, and __pthread_unwind_next to use,
any increase in the size of __pthread_unwind_buf_t causes these
functions to write beyond the original structure into other
on-stack variables leading to segmentation faults in common
applications like vlc. The only workaround is to version those
functions which operate on the old sized objects, but this must
happen in glibc 2.28.
Thank you to Andrew Senkevich, H.J. Lu, and Aurelien Jarno, for
submitting reports and tracking the issue down.
The commit reverts the above mentioned commits and testing on
x86_64 shows that the ABI compatibility is restored. A tst-cleanup1
regression test linked with an older glibc now passes when run
with the newly built glibc. Previously a tst-cleanup1 linked with
an older glibc would segfault when run with an affected glibc build.
Tested on x86_64 with no regressions.

The RISC-V port defines ELF flags that enforce compatibility between
various objects. This adds the shared support necessary for these
flags.
2018-01-25 Palmer Dabbelt <palmer@sifive.com>
* elf/cache.c (print_entry): Add FLAG_RISCV_FLOAT_ABI_SOFT and
FLAG_RISCV_FLOAT_ABI_DOUBLE.
* elf/elf.h (EF_RISCV_RVC): New define.
(EF_RISCV_FLOAT_ABI): Likewise.
(EF_RISCV_FLOAT_ABI_SOFT): Likewise.
(EF_RISCV_FLOAT_ABI_SINGLE): Likewise.
(EF_RISCV_FLOAT_ABI_DOUBLE): Likewise.
(EF_RISCV_FLOAT_ABI_QUAD): Likewise.
* sysdeps/generic/ldconfig.h (FLAG_RISCV_FLOAT_ABI_SOFT): New
define.
(FLAG_RISCV_FLOAT_ABI_DOUBLE): Likewise.
The arguments of the LIBC_SLIBDIR_RTLDDIR macro are used both in unquoted
and single quoted context, so that neither shell nor makefile variable
references work. Consistently put them in single quotes so that they can
refer to makefile variables.
Since it turns out soft-float ColdFire has a different glibc ABI to
hard-float ColdFire, as well as various differences in which glibc
code gets built, this patch adds such a configuration to
build-many-glibcs.py to (hopefully) complete the set of ABIs being
tested. (Note that the build for soft-float ColdFire is currently
broken even with GCC mainline - I have a glibc patch to fix this, but
it needs before-and-after build-many-glibcs.py comparison of stripped
binaries for all configurations before being committed.)
* scripts/build-many-glibcs.py (Context.add_all_configs): Add
soft-float ColdFire configuration.
