aarch64: use PTR_ARG and SIZE_ARG instead of DELOUSE
|
||||
|
||||
DELOUSE was added to asm code to make them compatible with non-LP64
|
||||
ABIs, but it is an unfortunate name and the code was not compatible
|
||||
with ABIs where pointer and size_t are different. Glibc currently
|
||||
only supports the LP64 ABI so these macros are not really needed or
|
||||
tested, but for now the name is changed to be more meaningful instead
|
||||
of removing them completely.
|
||||
|
||||
Some DELOUSE macros were dropped: clone, strlen and strnlen used it
|
||||
unnecessarily.
|
||||
|
||||
The out of tree ILP32 patches are currently not maintained and will
|
||||
likely need a rework to rebase them on top of the time64 changes.
|
||||
|
||||
Keeping the DELOUSE macro avoids the need to update all string
|
||||
functions. Lack of BTI markers and architecture variants cause many
|
||||
conflicts in a full upstream backport.

aarch64: Added optimized memcpy and memmove for A64FX
|
||||
|
||||
This patch optimizes the performance of memcpy/memmove for A64FX [1]
|
||||
which implements ARMv8-A SVE and has L1 64KB cache per core and L2 8MB
|
||||
cache per NUMA node.
|
||||
|
||||
The performance optimization makes use of Scalable Vector Register
|
||||
with several techniques such as loop unrolling, memory access
|
||||
alignment, cache zero fill, and software pipelining.
|
||||
|
||||
SVE assembler code for memcpy/memmove is implemented as Vector Length
|
||||
Agnostic code so theoretically it can be run on any SOC which supports
|
||||
ARMv8-A SVE standard.
|
||||
|
||||
We confirmed that all testcases have been passed by running 'make
|
||||
check' and 'make xcheck' not only on A64FX but also on ThunderX2.
|
||||
|
||||
And also we confirmed that the SVE 512 bit vector register performance
|
||||
is roughly 4 times better than Advanced SIMD 128 bit register and 8
|
||||
times better than scalar 64 bit register by running 'make bench'.

commit 4f26956d5ba394eb3ade6c1c20b5c16864a00766

aarch64: Added optimized memset for A64FX
|
||||
|
||||
This patch optimizes the performance of memset for A64FX [1] which
|
||||
implements ARMv8-A SVE and has L1 64KB cache per core and L2 8MB cache
|
||||
per NUMA node.
|
||||
|
||||
The performance optimization makes use of Scalable Vector Register
|
||||
with several techniques such as loop unrolling, memory access
|
||||
alignment, cache zero fill and prefetch.
|
||||
|
||||
SVE assembler code for memset is implemented as Vector Length Agnostic
|
||||
code so theoretically it can be run on any SOC which supports ARMv8-A
|
||||
SVE standard.
|
||||
|
||||
We confirmed that all testcases have been passed by running 'make
|
||||
check' and 'make xcheck' not only on A64FX but also on ThunderX2.
|
||||
|
||||
And also we confirmed that the SVE 512 bit vector register performance
|
||||
is roughly 4 times better than Advanced SIMD 128 bit register and 8
|
||||
times better than scalar 64 bit register by running 'make bench'.

Subject: elf: Always set l in _dl_init_paths (bug 23462)
|
||||
|
||||
After d1d5471579eb0426671bf94f2d71e61dfb204c30 ("Remove dead
|
||||
DL_DST_REQ_STATIC code.") we always setup the link map l to make the
|
||||
static and shared cases the same. The bug is that in elf/dl-load.c
|
||||
(_dl_init_paths) we conditionally set l only in the #ifdef SHARED
|
||||
case, but unconditionally use it later. The simple solution is to
|
||||
remove the #ifdef SHARED conditional, because it's no longer needed,
|
||||
and unconditionally setup l for both the static and shared cases. A
|
||||
regression test is added to run a static binary with
|
||||
LD_LIBRARY_PATH='$ORIGIN' which crashes before the fix and runs after
|
||||
the fix.

Subject: elf: ld.so --help calls _dl_init_paths without a main map [BZ #27577]
|
||||
|
||||
In this case, use the link map of the dynamic loader itself as
|
||||
a replacement. This is more than just a hack: if we ever support
|
||||
DT_RUNPATH/DT_RPATH for the dynamic loader, reporting it for
|
||||
ld.so --help (without further command line arguments) would be the
|
||||
right thing to do.
|
||||
|
||||
Fixes commit 332421312576bd7095e70589154af99b124dd2d1 ("elf: Always

x86: Properly disable XSAVE related features [BZ #27605]
|
||||
|
||||
1. Support GLIBC_TUNABLES=glibc.cpu.hwcaps=-XSAVE.
|

2. Disable all features which depend on XSAVE:
|
||||
a. If OSXSAVE is disabled by glibc tunables. Or
|
||||
b. If both XSAVE and XSAVEC aren't usable.

Handle DT_UNKNOWN in gconv-modules.d
|
||||
|
||||
On filesystems that do not support dt_type, a regular file shows up as
|
||||
DT_UNKNOWN. Fall back to using lstat64 to read file properties in
|
||||
such cases.

iconvconfig: Fix multiple issues
|
||||
|
||||
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.

iconvconfig: Fix behaviour with --prefix [BZ #28199]
|
||||
|
||||
The consolidation of configuration parsing broke behaviour with
|
||||
--prefix, where the prefix bled into the modules cache. Accept a
|
||||
prefix which, when non-NULL, is prepended to the path when looking for
|
||||
configuration files but only the original directory is added to the
|
||||
modules cache.
|
||||
|
||||
This has no effect on the codegen of gconv_conf since it passes NULL.

iconvconfig: Read configuration from gconv-modules.d subdirectory
|
||||
|
||||
In addition to GCONV_PATH/gconv-modules, also read module
|
||||
configuration from *.conf files in GCONV_PATH/gconv-modules.d. This
|
||||
allows a single gconv directory to have multiple sets of gconv modules
|
||||
but at the same time, a single modules cache.
|
||||
|
||||
With this feature, one could separate the glibc supported gconv
|
||||
modules into a minimal essential set (ISO-8859-*, UTF, etc.) from the
|
||||
remaining modules. In future, these could be further segregated into
|
||||
langpack-associated sets with their own
|
||||
gconv-modules.d/someconfig.conf.

iconvdata: Move gconv-modules configuration to gconv-modules.conf
|
||||
|
||||
Move all gconv-modules configuration files to gconv-modules.conf.
|
||||
That is, the S390 extensions now become gconv-modules-s390.conf. Move
|
||||
both configuration files into gconv-modules.d.
|
||||
|
||||
Now GCONV_PATH/gconv-modules is read only for backward compatibility
|
||||
for third-party gconv modules directories.

Reinstate gconv-modules as the default configuration file
|
||||
|
||||
Reinstate gconv-modules as the main file so that the configuration
|
||||
files in gconv-modules.d/ become add-on configuration. With this, the
|
||||
effective user visible change is that GCONV_PATH can now have
|
||||
supplementary configuration in GCONV_PATH/gconv-modules.d/ in addition
|
||||
to the main GCONV_PATH/gconv-modules file.

iconv: Remove alloca use in gconv-modules configuration parsing
|
||||
|
||||
The alloca sizes ought to be constrained to PATH_MAX, but replace them
|
||||
with dynamic allocation to be safe. A static PATH_MAX array would
|
||||
have worked too but Hurd does not have PATH_MAX and the code path is
|
||||
not hot enough to micro-optimise this allocation. Revisit if any of
|
||||
those realities change.

gconv_conf: Remove unused variables
|
||||
|
||||
The modules and nmodules parameters passed to add_modules, add_alias,
|
||||
etc. are not used and are hence unnecessary. Remove them so that
|
||||
their signatures match the functions in iconvconfig.

gconv_conf: Split out configuration file processing

Split configuration file processing into a separate header file and

include it. Macroize all calls that need to go through internal

interfaces so that iconvconfig can also use them.

powerpc: Optimized memcmp for power10
|
||||
|
||||
This patch was based on the __memcmp_power8 and the recent
|
||||
__strlen_power10.
|
||||
|
||||
Improvements from __memcmp_power8:
|
||||
|
||||
1. Don't need alignment code.
|
||||
|
||||
On POWER10 lxvp and lxvl do not generate alignment interrupts, so
|
||||
they are safe for use on caching-inhibited memory. Notice that the
|
||||
comparison on the main loop will wait for both VSR to be ready.
|
||||
Therefore aligning one of the input address does not improve
|
||||
performance. In order to align both registers a vperm is necessary
|
||||
which add too much overhead.
|
||||
|
||||
2. Uses new POWER10 instructions
|
||||
|
||||
This code uses lxvp to decrease contention on load by loading 32 bytes
|
||||
per instruction.
|
||||
The vextractbm is used to have a smaller tail code for calculating the
|
||||
return value.
|
||||
|
||||
3. Performance improvement
|
||||
|
||||
This version has around 35% better performance on average. I saw no
|
||||
performance regressions for any length or alignment.
|
||||
|
||||
Thanks Matheus for helping me out with some details.

commit 813c6ec808556553be9d39e900a3fc97ceb32330

powerpc: optimize strcpy/stpcpy for POWER9/10
|
||||
|
||||
This patch modifies the current POWER9 implementation of strcpy and
|
||||
stpcpy to optimize it for POWER9/10.
|
||||
|
||||
Since no new POWER10 instructions are used, the original POWER9 strcpy is
|
||||
modified instead of creating a new implementation for POWER10. This
|
||||
implementation is based on both the original POWER9 implementation of
|
||||
strcpy and the preamble of the new POWER10 implementation of strlen.
|
||||
|
||||
The changes also affect stpcpy, which uses the same implementation with
|
||||
some additional code before returning.
|
||||
|
||||
On POWER9, averaging improvements across the benchmark
|
||||
inputs (length/source alignment/destination alignment), for an
|
||||
experiment that ran the benchmark five times, bench-strcpy showed an
|
||||
improvement of 5.23%, and bench-stpcpy showed an improvement of 6.59%.
|
||||
|
||||
On POWER10, bench-strcpy showed 13.16%, and bench-stpcpy showed 13.59%.
|
||||
|
||||
The changes are:
|
||||
|
||||
1. Removed the null string optimization.
|
||||
|
||||
Although this results in a few extra cycles for the null string, in
|
||||
combination with the second change, this resulted in improvements for
|
||||
for other cases.
|
||||
|
||||
2. Adapted the preamble from strlen for POWER10.
|
||||
|
||||
This is the part of the function that handles up to the first 16 bytes
|
||||
of the string.
|
||||
|
||||
3. Increased number of unrolled iterations in the main loop to 6.

Subject: [PATCH] S390: Sync HWCAP names with kernel by adding aliases [BZ
|
||||
#25971]
|
||||
|
||||
Unfortunately some HWCAP names like HWCAP_S390_VX differs between
|
||||
kernel (see <kernel>/arch/s390/include/asm/elf.h) and glibc.
|
||||
|
||||
Therefore, those HWCAP names from kernel are now introduced as alias

Subject: [PATCH] S390: Add PCI_MIO and SIE HWCAPs
|
||||
|
||||
Both new HWCAPs were introduced in these kernel commits:
|
||||
- 7e8403ecaf884f307b627f3c371475913dd29292
|
||||
"s390: add HWCAP_S390_PCI_MIO to ELF hwcaps"
|
||||
- 7e82523f2583e9813e4109df3656707162541297
|
||||
"s390/hwcaps: make sie capability regular hwcap"
|
||||
|
||||
Also note that the kernel commit 511ad531afd4090625def4d9aba1f5227bd44b8e
|
||||
"s390/hwcaps: shorten HWCAP defines" has shortened the prefix of the macros
|
||||
from "HWCAP_S390_" to "HWCAP_". For compatibility reasons, we do not
|
||||
change the prefix in public glibc header file.

elf: Remove lazy tlsdesc relocation related code
|
||||
|
||||
Remove generic tlsdesc code related to lazy tlsdesc processing since
|
||||
lazy tlsdesc relocation is no longer supported. This includes removing
|
||||
GL(dl_load_lock) from _dl_make_tlsdesc_dynamic which is only called at
|
||||
load time when that lock is already held.
|
||||
|
||||
Added a documentation comment too.

elf: Fix data races in pthread_create and TLS access [BZ #19329]
|
||||
|
||||
DTV setup at thread creation (_dl_allocate_tls_init) is changed
|
||||
to take the dlopen lock, GL(dl_load_lock). Avoiding data races
|
||||
here without locks would require design changes: the map that is
|
||||
accessed for static TLS initialization here may be concurrently
|
||||
freed by dlclose. That use after free may be solved by only
|
||||
locking around static TLS setup or by ensuring dlclose does not
|
||||
free modules with static TLS, however currently every link map
|
||||
with TLS has to be accessed at least to see if it needs static
|
||||
TLS. And even if that's solved, still a lot of atomics would be
|
||||
needed to synchronize DTV related globals without a lock. So fix
|
||||
both bug 19329 and bug 27111 with a lock that prevents DTV setup
|
||||
running concurrently with dlopen or dlclose.
|
||||
|
||||
_dl_update_slotinfo at TLS access still does not use any locks
|
||||
so CONCURRENCY NOTES are added to explain the synchronization.
|
||||
The early exit from the slotinfo walk when max_modid is reached
|
||||
is not strictly necessary, but does not hurt either.
|
||||
|
||||
An incorrect acquire load was removed from _dl_resize_dtv: it
|
||||
did not synchronize with any release store or fence and
|
||||
synchronization is now handled separately at thread creation
|
||||
and TLS access time.
|
||||
|
||||
There are still a number of racy read accesses to globals that
|
||||
will be changed to relaxed MO atomics in a followup patch. This
|
||||
should not introduce regressions compared to existing behaviour
|
||||
and avoid cluttering the main part of the fix.
|
||||
|
||||
Not all TLS access related data races got fixed here: there are
|
||||
additional races at lazy tlsdesc relocations see bug 27137.

elf: Use relaxed atomics for racy accesses [BZ #19329]
|
||||
|
||||
This is a follow up patch to the fix for bug 19329. This adds relaxed
|
||||
MO atomics to accesses that were previously data races but are now
|
||||
race conditions, and where relaxed MO is sufficient.
|
||||
|
||||
The race conditions all follow the pattern that the write is behind the
|
||||
dlopen lock, but a read can happen concurrently (e.g. during tls access)
|
||||
without holding the lock. For slotinfo entries the read value only
|
||||
matters if it reads from a synchronized write in dlopen or dlclose,
|
||||
otherwise the related dtv entry is not valid to access so it is fine
|
||||
to leave it in an inconsistent state. The same applies for
|
||||
GL(dl_tls_max_dtv_idx) and GL(dl_tls_generation), but there the
|
||||
algorithm relies on the fact that the read of the last synchronized
|
||||
write is an increasing value.

elf: Add test case for [BZ #19329]
|
||||
|
||||
Test concurrent dlopen and pthread_create when the loaded modules have
|
||||
TLS. This triggers dl-tls assertion failures more reliably than the
|
||||
nptl/tst-stack4 test.
|
||||
|
||||
The dlopened module has 100 DT_NEEDED dependencies with TLS, they were
|
||||
reused from an existing TLS test. The number of created threads during
|
||||
dlopen depends on filesystem speed and hardware, but at most 3 threads
|
||||
are alive at a time to limit resource usage.

elf: Fix DTV gap reuse logic [BZ #27135]
|
||||
|
||||
For some reason only dlopen failure caused dtv gaps to be reused.
|
||||
|
||||
It is possible that the intent was to never reuse modids for a
|
||||
different module, but after dlopen failure all gaps are reused
|
||||
not just the ones caused by the unfinished dlopened.
|
||||
|
||||
So the code has to handle reused modids already which seems to
|
||||
work, however the data races at thread creation and tls access
|
||||
(see bug 19329 and bug 27111) may be more severe if slots are
|
||||
reused so this is scheduled after those fixes. I think fixing
|
||||
the races are not simpler if reuse is disallowed and reuse has
|
||||
other benefits, so set GL(dl_tls_dtv_gaps) whenever entries are
|
||||
removed from the middle of the slotinfo list. The value does
|
||||
not have to be correct: incorrect true value causes the next
|
||||
modid query to do a slotinfo walk, incorrect false will leave
|
||||
gaps and new entries are added at the end.
|
||||
|
||||
Fixes bug 27135.

elf: Disable most of TLS modid gaps processing [BZ #27135]
|
||||
|
||||
Revert "elf: Fix DTV gap reuse logic [BZ #27135]"
|
||||
|
||||
This reverts commit 572bd547d57a39b6cf0ea072545dc4048921f4c3.
|
||||
|
||||
It turns out that the _dl_next_tls_modid in _dl_map_object_from_fd keeps
|
||||
returning the same modid over and over again if there is a gap and
|
||||
more than TLS-using module is loaded in one dlopen call. This corrupts
|
||||
TLS data structures. The bug is still present after a revert, but
|
||||
empirically it is much more difficult to trigger (because it involves a
|
||||
dlopen failure).

elf: Fix DTV gap reuse logic (BZ #27135)
|
||||
|
||||
This is updated version of the 572bd547d57a (reverted by 40ebfd016ad2)
|
||||
that fixes the _dl_next_tls_modid issues.
|
||||
|
||||
This issue with 572bd547d57a patch is the DTV entry will be only
|
||||
update on dl_open_worker() with the update_tls_slotinfo() call after
|
||||
all dependencies are being processed by _dl_map_object_deps(). However
|
||||
_dl_map_object_deps() itself might call _dl_next_tls_modid(), and since
|
||||
the _dl_tls_dtv_slotinfo_list::map is not yet set the entry will be
|
||||
wrongly reused.
|
||||
|
||||
This patch fixes by renaming the _dl_next_tls_modid() function to
|
||||
_dl_assign_tls_modid() and by passing the link_map so it can set
|
||||
the slotinfo value so a subsequente _dl_next_tls_modid() call will
|
||||
see the entry as allocated.
|
||||
|
||||
The intermediary value is cleared up on remove_slotinfo() for the case
|
||||
a library fails to load with RTLD_NOW.
|
||||
|
||||
This patch fixes BZ #27135.
|
||||
|
||||
Checked on x86_64-linux-gnu.

elf: Avoid deadlock between pthread_create and ctors [BZ #28357]
|
||||
|
||||
The fix for bug 19329 caused a regression such that pthread_create can
|
||||
deadlock when concurrent ctors from dlopen are waiting for it to finish.
|
||||
Use a new GL(dl_load_tls_lock) in pthread_create that is not taken
|
||||
around ctors in dlopen.
|
||||
|
||||
The new lock is also used in __tls_get_addr instead of GL(dl_load_lock).
|
||||
|
||||
The new lock is held in _dl_open_worker and _dl_close_worker around
|
||||
most of the logic before/after the init/fini routines. When init/fini
|
||||
routines are running then TLS is in a consistent, usable state.
|
||||
In _dl_open_worker the new lock requires catching and reraising dlopen
|
||||
failures that happen in the critical section.
|
||||
|
||||
The new lock is reinitialized in a fork child, to keep the existing
|
||||
behaviour and it is kept recursive in case malloc interposition or TLS
|
||||
access from signal handlers can retake it. It is not obvious if this
|
||||
is necessary or helps, but avoids changing the preexisting behaviour.
|
||||
|
||||
The new lock may be more appropriate for dl_iterate_phdr too than
|
||||
GL(dl_load_write_lock), since TLS state of an incompletely loaded

elf: Fix a DTV setup issue [BZ #27136]
|
||||
|
||||
The max modid is a valid index in the dtv, it should not be skipped.
|
||||
|
||||
The bug is observable if the last module has modid == 64 and its
|
||||
generation is same or less than the max generation of the previous
|
||||
modules. Then dtv[0].counter implies dtv[64] is initialized but
|
||||
it isn't. Fixes bug 27136.

nptl: Add one more barrier to nptl/tst-create1
|
||||
|
||||
Without the bar_ctor_finish barrier, it was possible that thread2
|
||||
re-locked user_lock before ctor had a chance to lock it. ctor then
|
||||
blocked in its locking operation, xdlopen from the main thread
|
||||
did not return, and thread2 was stuck waiting in bar_dtor:
|
||||
|
||||
thread 1: started.
|
||||
thread 2: started.
|
||||
thread 2: locked user_lock.
|
||||
constructor started: 0.
|
||||
thread 1: in ctor: started.
|
||||
thread 3: started.

thread 3: done.

elf: Add a DTV setup test [BZ #27136]
|
||||
|
||||
The test dlopens a large number of modules with TLS, they are reused
|
||||
from an existing test.
|
||||
|
||||
The test relies on the reuse of slotinfo entries after dlclose, without
|
||||
bug 27135 fixed this needs a failing dlopen. With a slotinfo list that
|
||||
has non-monotone increasing generation counters, bug 27136 can trigger.

elf: Fix comments and logic in _dl_add_to_slotinfo

Since

|
||||
commit a509eb117fac1d764b15eba64993f4bdb63d7f3c
|
||||
Avoid late dlopen failure due to scope, TLS slotinfo updates [BZ #25112]
|
||||
|
||||
the generation counter update is not needed in the failure path.
|
||||
That commit ensures allocation in _dl_add_to_slotinfo happens before
|
||||
the demarcation point in dlopen (it is called twice, first time is for
|
||||
allocation only where dlopen can still be reverted on failure, then
|
||||
second time actual dtv updates are done which then cannot fail).

elf: Refactor _dl_update_slotinfo to avoid use after free
|
||||
|
||||
map is not valid to access here because it can be freed by a concurrent
|
||||
dlclose: during tls access (via __tls_get_addr) _dl_update_slotinfo is
|
||||
called without holding dlopen locks. So don't check the modid of map.
|
||||
|
||||
The map == 0 and map != 0 code paths can be shared (avoiding the dtv
|
||||
resize in case of map == 0 is just an optimization: larger dtv than
|
||||
necessary would be fine too).

x86_64: Avoid lazy relocation of tlsdesc [BZ #27137]
|
||||
|
||||
Lazy tlsdesc relocation is racy because the static tls optimization and
|
||||
tlsdesc management operations are done without holding the dlopen lock.
|
||||
|
||||
This similar to the commit b7cf203b5c17dd6d9878537d41e0c7cc3d270a67
|
||||
for aarch64, but it fixes a different race: bug 27137.
|
||||
|
||||
Another issue is that ld auditing ignores DT_BIND_NOW and thus tries to
|
||||
relocate tlsdesc lazily, but that does not work in a BIND_NOW module
|
||||
due to missing DT_TLSDESC_PLT. Unconditionally relocating tlsdesc at
|
||||
load time fixes this bug 27721 too.

Bug RHEL #2000374
|
||||
Bugs Upstream #24046, #25923
|
||||
|
||||
This patch provides 12-hour time for the English language UTF-8 locale as a
|
||||
new locale en_US@ampm.UTF-8.
|
||||
|
||||
Two upstream commits were applied to en_US to create the new file en_US@ampm:
|
||||
Upstream commit: 7395f3a0efad9fc51bb54fa383ef6524702e0c49
|
||||
Upstream commit: 8cde977077b3568310c743b21a905ca9ab286724
|
||||
|
||||
en_US remains unchanged and the new file en_US@ampm is now supported.

[PATCH] pthread_once hangs when init routine throws an exception [BZ #18435]
|
||||
|
||||
This is another attempt at making pthread_once handle throwing exceptions
|
||||
from the init routine callback. As the new testcases show, just switching
|
||||
to the cleanup attribute based cleanup does fix the tst-once5 test, but
|
||||
breaks the new tst-oncey3 test. That is because when throwing exceptions,
|
||||
only the unwind info registered cleanups (i.e. C++ destructors or cleanup
|
||||
attribute), when cancelling threads and there has been unwind info from the
|
||||
cancellation point up to whatever needs cleanup both unwind info registered
|
||||
cleanups and THREAD_SETMEM (self, cleanup, ...) registered cleanups are
|
||||
invoked, but once we hit some frame with no unwind info, only the
|
||||
THREAD_SETMEM (self, cleanup, ...) registered cleanups are invoked.
|
||||
So, to stay fully backwards compatible (allow init routines without
|
||||
unwind info which encounter cancellation points) and handle exception throwing
|
||||
we actually need to register the pthread_once cleanups in both unwind info
|
||||
and in the THREAD_SETMEM (self, cleanup, ...) way.
|
||||
If an exception is thrown, only the former will happen and we in that case
|
||||
need to also unregister the THREAD_SETMEM (self, cleanup, ...) registered
|
||||
handler, because otherwise after catching the exception the user code could
|
||||
call deeper into the stack some cancellation point, get cancelled and then
|
||||
a stale cleanup handler would clobber stack and probably crash.
|
||||
If a thread calling init routine is cancelled and unwind info ends before
|
||||
the pthread_once frame, it will be cleaned up through self->cleanup as
|
||||
before. And if unwind info is present, unwind_stop first calls the
|
||||
self->cleanup registered handler for the frame, then it will call the
|
||||
unwind info registered handler but that will already see __do_it == 0
|
||||
and do nothing.

s390: Use long branches across object boundaries (jgh instead of jh)
|
||||
|
||||
Depending on the layout chosen by the linker, the 16-bit displacement
|

of the jh instruction is insufficient to reach the target label.
|
||||
|
||||
Analysis of the linker failure was carried out by Nick Clifton.

x86: Automate generation of PREFERRED_FEATURE_INDEX_1 bitfield
|
||||
|
||||
Use a .def file to define the bitfield layout, so that it is possible
|
||||
to iterate over field members using the preprocessor.

elf: execve statically linked programs instead of crashing [BZ #28648]
|
||||
|
||||
Programs without dynamic dependencies and without a program
|
||||
interpreter are now run via execve.
|
||||
|
||||
Previously, the dynamic linker either crashed while attempting to
|
||||
read a non-existing dynamic segment (looking for DT_AUDIT/DT_DEPAUDIT
|
||||
data), or the self-relocated in the static PIE executable crashed
|
||||
because the outer dynamic linker had already applied RELRO protection.
|
||||
|
||||
<dl-execve.h> is needed because execve is not available in the
|
||||
dynamic loader on Hurd.

elf: Install a symbolic link to ld.so as /usr/bin/ld.so
|

|

This makes ld.so features such as --preload, --audit,
|

and --list-diagnostics more accessible to end users because they

do not need to know the ABI name of the dynamic loader.

timezone: handle truncated timezones from tzcode-2021d and later (BZ #28707)
|
||||
|
||||
When using a timezone file with a truncated starting time,
|
||||
generated by the zic in IANA tzcode-2021d a.k.a. tzlib-2021d
|
||||
(also in tzlib-2021e; current as of this writing), glibc
|
||||
asserts in __tzfile_read (on e.g. tzset() for this file) and
|
||||
you may find lines matching "tzfile.c:435: __tzfile_read:
|
||||
Assertion `num_types == 1' failed" in your syslog.
|
||||
|
||||
One example of such a file is the tzfile for Asuncion
|
||||
generated by tzlib-2021e as follows, using the tzlib-2021e zic:
|
||||
"zic -d DEST -r @1546300800 -L /dev/null -b slim
|
||||
SOURCE/southamerica". Note that in its type 2 header, it has
|
||||
two entries in its "time-types" array (types), but only one
|
||||
entry in its "transition types" array (type_idxs).
|
||||
|
||||
This is valid and expected already in the published RFC8536, and
|
||||
not even frowned upon: "Local time for timestamps before the
|
||||
first transition is specified by the first time type (time type
|
||||
0)" ... "every nonzero local time type index SHOULD appear at
|
||||
least once in the transition type array". Note the "nonzero ...
|
||||
index". Until the 2021d zic, index 0 has been shared by the
|
||||
first valid transition but with 2021d it's separate, set apart
|
||||
as a placeholder and only "implicitly" indexed. (A draft update
|
||||
of the RFC mandates that the entry at index 0 is a placeholder
|
||||
in this case, hence can no longer be shared.)
|
||||
|
||||
* time/tzfile.c (__tzfile_read): Don't assert when no transitions
|
||||
are found.

gconv: Do not emit spurious NUL character in ISO-2022-JP-3 (bug 28524)
|
||||
|
||||
Bugfix 27256 has introduced another issue:
|
||||
In conversion from ISO-2022-JP-3 encoding, it is possible
|
||||
to force iconv to emit extra NUL character on internal state reset.
|
||||
To do this, it is sufficient to feed iconv with escape sequence
|
||||
which switches active character set.
|
||||
The simplified check 'data->__statep->__count != ASCII_set'
|
||||
introduced by the aforementioned bugfix picks that case and
|
||||
behaves as if '\0' character has been queued thus emitting it.
|
||||
|
||||
To eliminate this issue, these steps are taken:
|
||||
* Restore original condition
|
||||
'(data->__statep->__count & ~7) != ASCII_set'.
|
||||
It is necessary since bits 0-2 may contain
|
||||
number of buffered input characters.
|
||||
* Check that queued character is not NUL.
|
||||
Similar step is taken for main conversion loop.
|
||||
|
||||
Bundled test case follows following logic:
|
||||
* Try to convert ISO-2022-JP-3 escape sequence
|
||||
switching active character set
|
||||
* Reset internal state by providing NULL as input buffer
|
||||
* Ensure that nothing has been converted.
