Usage: build-locale-archive [OPTION]... [TEMPLATE-FILE] [ARCHIVE-FILE]\n\
|
||||||
|
Builds a locale archive from a template file.\n\
|
||||||
|
Options:\n\
|
||||||
|
-h, --help Print this usage message.\n\
|
||||||
|
-v, --verbose Verbose execution.\n\
|
||||||
|
-l, --install-langs=LIST Only include locales given in LIST into the \n\
|
||||||
|
locale archive. LIST is a colon separated list\n\
|
||||||
|
of locale prefixes, for example \"de:en:ja\".\n\
|
||||||
|
The special argument \"all\" means to install\n\
|
||||||
|
all languages and it must be present by itself.\n\
|
||||||
|
If \"all\" is present with any other language it\n\
|
||||||
|
will be treated as the name of a locale.\n\
|
||||||
|
If the --install-langs option is missing, all\n\
|
||||||
|
locales are installed. The colon separated list\n\
|
||||||
|
can contain any strings matching the beginning of\n\
|
||||||
|
locale names.\n\
|
||||||
|
If a string does not contain a \"_\", it is added.\n\
|
||||||
|
Examples:\n\
|
||||||
|
--install-langs=\"en\"\n\
|
||||||
|
installs en_US, en_US.iso88591,\n\
|
||||||
|
en_US.iso885915, en_US.utf8,\n\
|
||||||
|
en_GB ...\n\
|
||||||
|
--install-langs=\"en_US.utf8\"\n\
|
||||||
|
installs only en_US.utf8.\n\
|
||||||
|
--install-langs=\"ko\"\n\
|
||||||
|
installs ko_KR, ko_KR.euckr,\n\
|
||||||
|
ko_KR.utf8 but *not* kok_IN\n\
|
||||||
|
because \"ko\" does not contain\n\
|
||||||
|
\"_\" and it is silently added\n\
|
||||||
|
--install-langs\"ko:kok\"\n\
|
||||||
|
installs ko_KR, ko_KR.euckr,\n\
|
||||||
|
ko_KR.utf8, kok_IN, and\n\
|
||||||
|
kok_IN.utf8.\n\
|
||||||
|
--install-langs=\"POSIX\" will\n\
|
||||||
|
installs *no* locales at all\n\
|
||||||
|
because POSIX matches none of\n\
|
||||||
|
the locales. Actually, any string\n\
|
||||||
|
matching nothing will do that.\n\
|
||||||
|
POSIX and C will always be\n\
|
||||||
|
available because they are\n\
|
||||||
|
builtin.\n\
|
||||||
|
Aliases are installed as well,\n\
|
||||||
|
i.e. --install-langs=\"de\"\n\
|
||||||
|
will install not only every locale starting with\n\
|
||||||
|
\"de\" but also the aliases \"deutsch\"\n\
|
||||||
|
and and \"german\" although the latter does not\n\
|
||||||
|
start with \"de\".\n\
|
||||||
|
\n\
|
||||||
|
If the arguments TEMPLATE-FILE and ARCHIVE-FILE are not given the locations\n\
|
||||||
|
where the glibc used expects these files are used by default.\n\

Submitted upstream here:

https://sourceware.org/ml/libc-alpha/2018-07/msg00077.html

Otherwise, we lose essential flags such as -Wa,--noexecstack due to
|
||||||
|
the way += works in make due to the ASFLAGS command line override.

Short description: Add C.UTF-8 support.
|
||||||
|
Author(s): Fedora glibc team <glibc@lists.fedoraproject.org>
|
||||||
|
Origin: PATCH
|
||||||
|
Upstream status: not-submitted
|
||||||
|
|
||||||
|
This patch needs to upstream as part of Carlos O'Donell
|
||||||
|
<carlos@redhat.com>'s work on enabling upstream C.UTF-8 support. This
|
||||||
|
work is currently blocked on cleaning up the test results to prove that
|
||||||
|
full code-point sorting is working as intended.
|
||||||
|
|
||||||
|
Note that this patch does not provide full code-point sorting as
|
||||||
|
expected.
|
||||||
|
|
||||||
|
This patch needs to upstream as soon as possible since it would be nice
|
||||||
|
to have this in F29 and fixed.

In Fedora we should return only /usr/bin because /bin is just a symlink

to /usr/bin after MoveToUsr transition (which glibc has not really

completed).

This patch needs to go upstream to get cleaned up, but has always involed
|
||||||
|
analysis of the GNU/Hurd parts of the change and that stalled out, but
|
||||||
|
perhaps with build-many-glibcs we can now test these changes more easily.

Short description: Fedora-specific workaround for kernel pty bug.
|

Author(s): Fedora glibc team <glibc@lists.fedoraproject.org>
|
||||||
|
Origin: PATCH
|

|
Upstream status: not-submitted
|
||||||
|
|
||||||
|
This is a Fedora-specific workaround for a kernel bug where calling
|
||||||
|
ioctl on a pty will silently ignore the invalid c_cflag. The
|
||||||
|
workaround is to use TCGETS to verify the setting matches. This is
|
||||||
|
not upstream and needs to either be removed or submitted upstream
|
||||||
|
after analysis.

Short description: Place glibc info into "Libraries" category.

||||||
|
The category names for libraries is completely random including
|
||||||
|
"Libraries", "GNU Libraries", "GNU libraries", and "Software libraries."
|
||||||
|
In the GNU info manual the "Software libraries" category is given as an
|
||||||
|
example, but really we need to standardize on a category for upstream.
|
||||||
|
I suggest we drop this change after some upstream discussion.

Short description: Fedora-specific enabling batch read in NSS.

Bug-RHEL: #188246

Enable batch read in NSS. It's not clear if this is always a win or
|
||||||
|
just a win for NIS+, this needs to be analyzed and sent upstream or
|
||||||
|
removed.

Short description: Do not define _XOPEN_STREAMS.

Bug-Fedora: #436349
|

|
Upstream status: not-submitted
|
||||||
|
|
||||||
|
This patch should go upstream. Not defining _XOPEN_STREAMS is the
|
||||||
|
same as setting it to -1 for POSIX conformance. The headers setting
|
||||||
|
needs to be reviewed indepedently.

Linux: Rewrite __old_getdents64 [BZ #23497]
|
||||||
|
|
||||||
|
Commit 298d0e3129c0b5137f4989275b13fe30d0733c4d ("Consolidate Linux
|
||||||
|
getdents{64} implementation") broke the implementation because it does
|
||||||
|
not take into account struct offset differences.
|
||||||
|
|
||||||
|
The new implementation is close to the old one, before the
|
||||||
|
consolidation, but has been cleaned up slightly.

Check multiple NT_GNU_PROPERTY_TYPE_0 notes [BZ #23509]
|
||||||
|
|
||||||
|
Linkers group input note sections with the same name into one output
|
||||||
|
note section with the same name. One output note section is placed in
|
||||||
|
one PT_NOTE segment. Since new linkers merge input .note.gnu.property
|
||||||
|
sections into one output .note.gnu.property section, there is only
|
||||||
|
one NT_GNU_PROPERTY_TYPE_0 note in one PT_NOTE segment with new linkers.
|
||||||
|
Since older linkers treat input .note.gnu.property section as a generic
|
||||||
|
note section and just concatenate all input .note.gnu.property sections
|
||||||
|
into one output .note.gnu.property section without merging them, we may
|
||||||
|
see multiple NT_GNU_PROPERTY_TYPE_0 notes in one PT_NOTE segment with
|
||||||
|
older linkers.
|
||||||
|
|
||||||
|
When an older linker is used to created the program on CET-enabled OS,
|
||||||
|
the linker output has a single .note.gnu.property section with multiple
|
||||||
|
NT_GNU_PROPERTY_TYPE_0 notes, some of which have IBT and SHSTK enable
|
||||||
|
bits set even if the program isn't CET enabled. Such programs will
|
||||||
|
crash on CET-enabled machines. This patch updates the note parser:
|
||||||
|
|
||||||
|
1. Skip note parsing if a NT_GNU_PROPERTY_TYPE_0 note has been processed.
|
||||||
|
2. Check multiple NT_GNU_PROPERTY_TYPE_0 notes.
|
||||||
|

[BZ #23509]

|
note parsing if a NT_GNU_PROPERTY_TYPE_0 note has been processed.

|
Update the l_cet field when processing NT_GNU_PROPERTY_TYPE_0 note.

|
Check multiple NT_GNU_PROPERTY_TYPE_0 notes.

Fix stack overflow in tst-setcontext9 (bug 23717)
|
||||||
|
|
||||||
|
The function f1a, executed on a stack of size 32k, allocates an object of
|
||||||
|
size 32k on the stack. Make the stack variables static to reduce
|
||||||
|
excessive stack usage.

commit a55e109709af55e6ed67d3f9536cac5d929c982e
|
||||||
|
Author: Carlos O'Donell <carlos@redhat.com>
|
||||||
|
Date: Wed Sep 5 01:16:42 2018 -0400
|
||||||
|
|
||||||
|
Fix tst-setcontext9 for optimized small stacks.
|
||||||
|
|
||||||
|
If the compiler reduces the stack usage in function f1 before calling
|
||||||
|
into function f2, then when we swapcontext back to f1 and continue
|
||||||
|
execution we may overwrite registers that were spilled to the stack
|
||||||
|
while f2 was executing. Later when we return to f2 the corrupt
|
||||||
|
registers will be reloaded from the stack and the test will crash. This
|
||||||
|
was most commonly observed on i686 with __x86.get_pc_thunk.dx and
|
||||||
|
needing to save and restore $edx. Overall i686 has few registers and
|
||||||
|
the spilling to the stack is bound to happen, therefore the solution to
|
||||||
|
making this test robust is to split function f1 into two parts f1a and
|
||||||
|
f1b, and allocate f1b it's own stack such that subsequent execution does
|
||||||
|
not overwrite the stack in use by function f2.
|
||||||
|
|
||||||
|
Tested on i686 and x86_64.

||||||

Fix strstr bug with huge needles (bug 23637)
|
||||||
|
|
||||||
|
The generic strstr in GLIBC 2.28 fails to match huge needles. The optimized
|
||||||
|
AVAILABLE macro reads ahead a large fixed amount to reduce the overhead of
|
||||||
|
repeatedly checking for the end of the string. However if the needle length
|
||||||
|
is larger than this, two_way_long_needle may confuse this as meaning the end
|
||||||
|
of the string and return NULL. This is fixed by adding the needle length to
|
||||||
|
the amount to read ahead.
|
||||||
|
|
||||||
|
[BZ #23637]
|
||||||
|
* string/test-strstr.c (pr23637): New function.
|
||||||
|
(test_main): Add tests with longer needles.
|
||||||
|
* string/strcasestr.c (AVAILABLE): Fix readahead distance.
|
||||||
|
* string/strstr.c (AVAILABLE): Likewise.

Fix _dl_profile_fixup data-dependency issue (Bug 23690)
|
||||||
|
|
||||||
|
There is a data-dependency between the fields of struct l_reloc_result
|
||||||
|
and the field used as the initialization guard. Users of the guard
|
||||||
|
expect writes to the structure to be observable when they also observe
|
||||||
|
the guard initialized. The solution for this problem is to use an acquire
|
||||||
|
and release load and store to ensure previous writes to the structure are
|
||||||
|
observable if the guard is initialized.
|
||||||
|
|
||||||
|
The previous implementation used DL_FIXUP_VALUE_ADDR (l_reloc_result->addr)
|
||||||
|
as the initialization guard, making it impossible for some architectures
|
||||||
|
to load and store it atomically, i.e. hppa and ia64, due to its larger size.
|
||||||
|
|
||||||
|
This commit adds an unsigned int to l_reloc_result to be used as the new
|
||||||
|
initialization guard of the struct, making it possible to load and store
|
||||||
|
it atomically in all architectures. The fix ensures that the values
|
||||||
|
observed in l_reloc_result are consistent and do not lead to crashes.
|
||||||
|
The algorithm is documented in the code in elf/dl-runtime.c
|
||||||
|
(_dl_profile_fixup). Not all data races have been eliminated.
|
||||||
|
|
||||||
|
Tested with build-many-glibcs and on powerpc, powerpc64, and powerpc64le.
|
||||||
|
|
||||||
|
[BZ #23690]
|
||||||
|

|
+ Multiple threads may be calling the same PLT sequence and with
|
||||||
|
+ LD_AUDIT enabled they will be calling into _dl_profile_fixup to
|
||||||
|
+ update the reloc_result with the result of the lazy resolution.
|
||||||
|
+ The reloc_result guard variable is reloc_init, and we use
|
||||||
|
+ acquire/release loads and store to it to ensure that the results of
|
||||||
|
+ the structure are consistent with the loaded value of the guard.
|
||||||
|
+ This does not fix all of the data races that occur when two or more
|

|
+ threads read reloc_result->reloc_init with a value of zero and read
|
||||||
|
+ and write to that reloc_result concurrently. The expectation is
|
||||||
|
+ generally that while this is a data race it works because the
|
||||||
|
+ threads write the same values. Until the data races are fixed
|
||||||
|
+ there is a potential for problems to arise from these data races.
|
||||||
|
+ The reloc result updates should happen in parallel but there should
|
||||||
|
+ be an atomic RMW which does the final update to the real result
|
||||||
|
+ entry (see bug 23790).
|

|
+

+ The following code uses reloc_result->init set to 0 to indicate if it is

Increase timeout of libio/tst-readline
|
||||||
|
|
||||||
|
Increase timeout from the default 20s to 100s. This test makes close to
|
||||||
|
20 million syscalls with distribution:
|
||||||
|
|
||||||
|
12327675 read
|
||||||
|
4143204 lseek
|
||||||
|
929475 close
|
||||||
|
929471 openat
|
||||||
|
92817 fstat
|
||||||
|
1431 write
|
||||||
|
...
|
||||||
|
|
||||||
|
The default timeout assumes each can finish in 1us on average which
|
||||||
|
is not true on slow machines.

commit 3bad2358d67d371497079bba4f8eca9c0096f4e2

Test stdlib/test-bz22786 exits now with unsupported if malloc fails.
|
||||||
|
|
||||||
|
The test tries to allocate more than 2^31 bytes which will always fail on s390
|
||||||
|
as it has maximum 2^31bit of memory.
|
||||||
|
Before commit 6c3a8a9d868a8deddf0d6dcc785b6d120de90523, this test returned
|
||||||
|
unsupported if malloc fails. This patch re enables this behaviour.
|
||||||
|
|
||||||
|
Furthermore support_delete_temp_files() failed to remove the temp directory
|
||||||
|
in this case as it is not empty due to the created symlink.
|
||||||
|
Thus the creation of the symlink is moved behind malloc.

stdlib/test-bz22786: Avoid spurious test failures using alias mappings
|
||||||
|
|
||||||
|
On systems without enough random-access memory, stdlib/test-bz22786
|
||||||
|
will go deeply into swap and time out, even with a substantial
|
||||||
|
TIMEOUTFACTOR. This commit adds a facility to construct repeating
|
||||||
|
strings with alias mappings, so that the requirement for physical
|
||||||
|
memory, and uses it in stdlib/test-bz22786.
|
||||||
|
|
||||||
|
Adjusted here for conflicts due to the previous support/ backport in
|
||||||
|
glibc-rh1638523-1.patch.

memusagestat: use local glibc when linking [BZ #18465]
|
||||||
|
|
||||||
|
The memusagestat is the only binary that has its own link line which
|
||||||
|
causes it to be linked against the existing installed C library. It
|
||||||
|
has been this way since it was originally committed in 1999, but I
|
||||||
|
don't see any reason as to why. Since we want all the programs we
|
||||||
|
build locally to be against the new copy of glibc, change the build
|
||||||
|
to be like all other programs.

benchtests: Enable BIND_NOW if configured with --enable-bind-now
|
||||||
|
|
||||||
|
Benchmarks should reflect distribution build policies, so it makes
|
||||||
|
sense to honor the BIND_NOW configuration for them.
|
||||||
|
|
||||||
|
This commit keeps using $(+link-tests), so that the benchmarks are
|
||||||
|
linked according to the --enable-hardcoded-path-in-tests configure
|
||||||
|
option.

Makeconfig: Move -Wl,-rpath-link options before library references
|
||||||
|
|
||||||
|
Previously, the -Wl,-rpath-link options came after the libraries
|
||||||
|
injected using LDLIBS-* variables on the link editor command line for
|
||||||
|
main programs. As a result, it could happen that installed libraries
|
||||||
|
that reference glibc libraries used the installed glibc from the system
|
||||||
|
directories, instead of the glibc from the build tree. This can lead to
|
||||||
|
link failures if the wrong version of libpthread.so.0 is used, for
|
||||||
|
instance, due to differences in the internal GLIBC_PRIVATE interfaces,
|
||||||
|
as seen with memusagestat and -lgd after commit
|
||||||
|
f9b645b4b0a10c43753296ce3fa40053fa44606a ("memusagestat: use local glibc
|
||||||
|
when linking [BZ #18465]").
|
||||||
|
|
||||||
|
The isolation is necessarily imperfect because these installed
|
||||||
|
libraries are linked against the installed glibc in the system
|
||||||
|
directories. However, in most cases, the built glibc will be newer
|
||||||
|
than the installed glibc, and this link is permitted because of the
|
||||||
|
ABI backwards compatibility glibc provides.

x86: Fix Haswell strong flags (BZ#23709)
|
||||||
|
|
||||||
|
Th commit 'Disable TSX on some Haswell processors.' (2702856bf4) changed the
|
||||||
|
default flags for Haswell models. Previously, new models were handled by the
|
||||||
|
default switch path, which assumed a Core i3/i5/i7 if AVX is available. After
|
||||||
|
the patch, Haswell models (0x3f, 0x3c, 0x45, 0x46) do not set the flags
|
||||||
|
Fast_Rep_String, Fast_Unaligned_Load, Fast_Unaligned_Copy, and
|
||||||
|
Prefer_PMINUB_for_stringop (only the TSX one).
|
||||||
|
|
||||||
|
This patch fixes it by disentangle the TSX flag handling from the memory
|
||||||
|
optimization ones. The strstr case cited on patch now selects the
|
||||||
|
__strstr_sse2_unaligned as expected for the Haswell cpu.
|
||||||
|
|
||||||
|
Checked on x86_64-linux-gnu.

malloc: tcache: Validate tc_idx before checking for double-frees [BZ #23907]
|
||||||
|
|

|
The previous check could read beyond the end of the tcache entry
|
||||||
|
array. If the e->key == tcache cookie check happened to pass, this
|
||||||
|
would result in crashes.

Fix segfault in maybe_script_execute.
|
||||||
|
|
||||||
|
If glibc is built with gcc 8 and -march=z900,
|
||||||
|
the testcase posix/tst-spawn4-compat crashes with a segfault.
|
||||||
|
|
||||||
|
In function maybe_script_execute, the new_argv array is dynamically
|
||||||
|
initialized on stack with (argc + 1) elements.
|
||||||
|
The function wants to add _PATH_BSHELL as the first argument
|
||||||
|
and writes out of bounds of new_argv.
|
||||||
|
There is an off-by-one because maybe_script_execute fails to count
|
||||||
|
the terminating NULL when sizing new_argv.
|
||||||
|
|
||||||
|
ChangeLog:
|
||||||
|
|
||||||
|
* sysdeps/unix/sysv/linux/spawni.c (maybe_script_execute):
|
||||||
|
Increment size of new_argv by one.

Fix misreported errno on preadv2/pwritev2 (BZ#23579)
|
||||||
|
|
||||||
|
The fallback code of Linux wrapper for preadv2/pwritev2 executes
|
||||||
|
regardless of the errno code for preadv2, instead of the case where
|
||||||
|
the syscall is not supported.
|
||||||
|
|
||||||
|
This fixes it by calling the fallback code iff errno is ENOSYS. The
|
||||||
|
patch also adds tests for both invalid file descriptor and invalid
|
||||||
|
iov_len and vector count.
|
||||||
|
|
||||||
|
The only discrepancy between preadv2 and fallback code regarding
|
||||||
|
error reporting is when an invalid flags are used. The fallback code
|
||||||
|
bails out earlier with ENOTSUP instead of EINVAL/EBADF when the syscall
|
||||||
|
is used.
|
||||||
|
|
||||||
|
Checked on x86_64-linux-gnu on a 4.4.0 and 4.15.0 kernel.
|
||||||
|

i386: Use _dl_runtime_[resolve|profile]_shstk for SHSTK [BZ #23716]
|
||||||
|
|
||||||
|
When elf_machine_runtime_setup is called to set up resolver, it should
|
||||||
|
use _dl_runtime_resolve_shstk or _dl_runtime_profile_shstk if SHSTK is
|
||||||
|
enabled by kernel.
|
||||||
|
|
||||||
|
Tested on i686 with and without --enable-cet as well as on CET emulator
|
||||||
|
with --enable-cet.
|
||||||
|
|
||||||
|
[BZ #23716]
|
||||||
|
* sysdeps/i386/dl-cet.c: Removed.
|
||||||
|
* sysdeps/i386/dl-machine.h (_dl_runtime_resolve_shstk): New
|
||||||
|
prototype.
|
||||||
|
(_dl_runtime_profile_shstk): Likewise.
|
||||||
|
(elf_machine_runtime_setup): Use _dl_runtime_profile_shstk or
|
||||||
|
_dl_runtime_resolve_shstk if SHSTK is enabled by kernel.

Fix race in pthread_mutex_lock while promoting to PTHREAD_MUTEX_ELISION_NP [BZ #23275]
|
||||||
|
|
||||||
|
The race leads either to pthread_mutex_destroy returning EBUSY
|
||||||
|
or triggering an assertion (See description in bugzilla).
|
||||||
|
|
||||||
|
This patch is fixing the race by ensuring that the elision path is
|
||||||
|
used in all cases if elision is enabled by the GLIBC_TUNABLES framework.
|
||||||
|
|
||||||
|
The __kind variable in struct __pthread_mutex_s is accessed concurrently.
|
||||||
|
Therefore we are now using the atomic macros.
|
||||||
|
|
||||||
|
The new testcase tst-mutex10 is triggering the race on s390x and intel.
|
||||||
|
Presumably also on power, but I don't have access to a power machine
|
||||||
|
with lock-elision. At least the code for power is the same as on the other
|
||||||
|
two architectures.
|
||||||
|
|
||||||
|
ChangeLog:
|
||||||
|
|
||||||
|
[BZ #23275]
|
||||||
|
* nptl/tst-mutex10.c: New File.
|
||||||
|
* nptl/Makefile (tests): Add tst-mutex10.
|
||||||
|
(tst-mutex10-ENV): New variable.
|
||||||
|
* sysdeps/unix/sysv/linux/s390/force-elision.h: (FORCE_ELISION):
|
||||||

|

|

|

|

|

|
+ For elision, there are the flags PTHREAD_MUTEX_ELISION_NP and
|
||||||
|
+ PTHREAD_MUTEX_NO_ELISION_NP which can be set in addition to the already set
|
||||||
|
+ type of a mutex.
|
||||||
|
+ Before a mutex is initialized, only PTHREAD_MUTEX_NO_ELISION_NP can be set
|
||||||
|
+ with pthread_mutexattr_settype.
|
||||||
|
+ After a mutex has been initialized, the functions pthread_mutex_*lock can
|
||||||
|
+ enable elision - if the mutex-type and the machine supports it - by setting
|
||||||
|
+ the flag PTHREAD_MUTEX_ELISION_NP. This is done concurrently. Afterwards
|

|
||||||
|
kernel on various architectures, so need to be mentioned in this file.

Update kernel version in syscall-names.list to 4.19.

Linux 4.19 does not add any new syscalls (some existing ones are added

to more architectures); this patch updates the version number in
|
||||||
|
syscall-names.list to reflect that it's still current for 4.19.

malloc: Verify size of top chunk.
|
||||||
|
|
||||||
|
The House of Force is a well-known technique to exploit heap
|
||||||
|
overflow. In essence, this exploit takes three steps:
|
||||||
|
1. Overwrite the size of top chunk with very large value (e.g. -1).
|
||||||
|
2. Request x bytes from top chunk. As the size of top chunk
|
||||||
|
is corrupted, x can be arbitrarily large and top chunk will
|
||||||
|
still be offset by x.
|
||||||
|
3. The next allocation from top chunk will thus be controllable.
|
||||||
|
|
||||||
|
If we verify the size of top chunk at step 2, we can stop such attack.

I'm fairly certain that it compares mchunk_size of victim against
|
||||||
|
mchunk_prev_size of the next chunk, i.e. the size of victim in its
|
||||||
|
header and footer.

You are right, I don't think it makes a difference in these checks. So
|
||||||
|
the size local can be reused for the checks against victim. For next,
|
||||||
|
leaving it as such avoids the masking operation.
|
||||||
|
|
||||||

|
||||||
|
|
||||||
|
We could also do a chunk boundary check similar to what I proposed in
|
||||||
|
the thread for the first patch in the series to be even more strict.
|
||||||
|
I'll gladly try to implement either but believe that refining these
|
||||||
|
checks would bring less benefits than in the case of the top chunk.
|
||||||
|
Intra-arena or intra-heap overlaps would still be doable here with
|
||||||
|
unsorted chunks and I don't see any way to counter that besides more
|
||||||
|
generic measures like randomizing allocations and your metadata
|
||||||
|
encoding patches.
|
||||||
|
|
||||||
|
I've attached a revised version with the above comments incorporated
|
||||||
|
but without the refined checks.

||||||

malloc: Check for large bin list corruption when inserting unsorted chunk
|
||||||
|
|
||||||
|
Fixes bug 24216. This patch adds security checks for bk and bk_nextsize pointers
|
||||||
|
of chunks in large bin when inserting chunk from unsorted bin. It was possible
|
||||||
|
to write the pointer to victim (newly inserted chunk) to arbitrary memory
|
||||||
|
locations if bk or bk_nextsize pointers of the next large bin chunk
|
||||||
|
got corrupted.

powerpc: Only enable TLE with PPC_FEATURE2_HTM_NOSC
|
||||||
|
|
||||||
|
Linux from 3.9 through 4.2 does not abort HTM transaction on syscalls,
|
||||||
|
instead it suspend and resume it when leaving the kernel. The
|
||||||
|
side-effects of the syscall will always remain visible, even if the
|
||||||
|
transaction is aborted. This is an issue when transaction is used along
|
||||||
|
with futex syscall, on pthread_cond_wait for instance, where the futex
|
||||||
|
call might succeed but the transaction is rolled back leading the
|
||||||
|
pthread_cond object in an inconsistent state.
|
||||||
|
|
||||||
|
Glibc used to prevent it by always aborting a transaction before issuing
|
||||||
|
a syscall. Linux 4.2 also decided to abort active transaction in
|
||||||
|
syscalls which makes the glibc workaround superfluous. Worse, glibc
|
||||||
|
transaction abortion leads to a performance issue on recent kernels
|
||||||
|
where the HTM state is saved/restore lazily (v4.9). By aborting a
|
||||||
|
transaction on every syscalls, regardless whether a transaction has being
|
||||||
|
initiated before, GLIBS makes the kernel always save/restore HTM state
|
||||||
|
(it can not even lazily disable it after a certain number of syscall
|
||||||
|
iterations).
|
||||||
|
|
||||||
|
Because of this shortcoming, Transactional Lock Elision is just enabled
|
||||||
|
when it has been explicitly set (either by tunables of by a configure
|
||||||
|
switch) and if kernel aborts HTM transactions on syscalls
|
||||||
|
(PPC_FEATURE2_HTM_NOSC). It is reported that using simple benchmark [1],
|
||||||
|
the context-switch is about 5% faster by not issuing a tabort in every
|
||||||
|
syscall in newer kernels.
|
||||||
|
|
||||||
|
Checked on powerpc64le-linux-gnu with 4.4.0 kernel (Ubuntu 16.04).

Fix rwlock stall with PREFER_WRITER_NONRECURSIVE_NP (bug 23861)
|
||||||
|
|
||||||
|
In the read lock function (__pthread_rwlock_rdlock_full) there was a
|
||||||
|
code path which would fail to reload __readers while waiting for
|
||||||
|
PTHREAD_RWLOCK_RWAITING to change. This failure to reload __readers
|
||||||
|
into a local value meant that various conditionals used the old value
|
||||||
|
of __readers and with only two threads left it could result in an
|
||||||
|
indefinite stall of one of the readers (waiting for PTHREAD_RWLOCK_RWAITING
|
||||||
|
to go to zero, but it never would).

nptl: Fix pthread_rwlock_try*lock stalls (Bug 23844)
|
||||||
|
|
||||||
|
For a full analysis of both the pthread_rwlock_tryrdlock() stall
|
||||||
|
and the pthread_rwlock_trywrlock() stall see:
|
||||||
|
https://sourceware.org/bugzilla/show_bug.cgi?id=23844#c14
|
||||||
|
|
||||||
|
In the pthread_rwlock_trydlock() function we fail to inspect for
|
||||||
|
PTHREAD_RWLOCK_FUTEX_USED in __wrphase_futex and wake the waiting
|
||||||
|
readers.
|
||||||
|
|
||||||
|
In the pthread_rwlock_trywrlock() function we write 1 to
|
||||||
|
__wrphase_futex and loose the setting of the PTHREAD_RWLOCK_FUTEX_USED
|
||||||
|
bit, again failing to wake waiting readers during unlock.
|
||||||
|
|
||||||
|
The fix in the case of pthread_rwlock_trydlock() is to check for
|
||||||
|
PTHREAD_RWLOCK_FUTEX_USED and wake the readers.
|
||||||
|
|
||||||
|
The fix in the case of pthread_rwlock_trywrlock() is to only write
|
||||||
|
1 to __wrphase_futex if we installed the write phase, since all other
|
||||||
|
readers would be spinning waiting for this step.
|
||||||
|
|
||||||
|
We add two new tests, one exercises the stall for
|
||||||
|
pthread_rwlock_trywrlock() which is easy to exercise, and one exercises
|
||||||
|
the stall for pthread_rwlock_trydlock() which is harder to exercise.
|
||||||
|
|
||||||
|
The pthread_rwlock_trywrlock() test fails consistently without the fix,
|
||||||
|
and passes after. The pthread_rwlock_tryrdlock() test fails roughly
|
||||||
|
5-10% of the time without the fix, and passes all the time after.

+ --- Analysis of pthread_rwlock_tryrdlock() stall ---
|
||||||
|
+ A read lock begins to execute.
|
||||||
|
+
|
||||||
|
+ In __pthread_rwlock_rdlock_full:
|
||||||
|
+
|
||||||
|
+ We can attempt a read lock, but find that the lock is
|
||||||
|
+ in a write phase (PTHREAD_RWLOCK_WRPHASE, or WP-bit
|
||||||
|
+ is set), and the lock is held by a primary writer
|
||||||
|
+ (PTHREAD_RWLOCK_WRLOCKED is set). In this case we must
|
||||||
|
+ wait for explicit hand over from the writer to us or
|
||||||
|
+ one of the other waiters. The read lock threads are
|
||||||
|
+ about to execute:
|
||||||
|
+
|
||||||
|
+ 341 r = (atomic_fetch_add_acquire (&rwlock->__data.__readers,
|
||||||
|
+ 342 (1 << PTHREAD_RWLOCK_READER_SHIFT))
|
||||||
|

|
||||||
|
+
|
||||||
|
+ An unlock beings to execute.
|
||||||
|
+
|
||||||
|
+ Then in __pthread_rwlock_wrunlock:
|
||||||
|
+
|
||||||
|
+ 547 unsigned int r = atomic_load_relaxed (&rwlock->__data.__readers);
|
||||||
|
+ ...
|
||||||
|
+ 549 while (!atomic_compare_exchange_weak_release
|
||||||
|
+ 550 (&rwlock->__data.__readers, &r,
|
||||||
|
+ 551 ((r ^ PTHREAD_RWLOCK_WRLOCKED)
|
||||||
|
+ 552 ^ ((r >> PTHREAD_RWLOCK_READER_SHIFT) == 0 ? 0
|
||||||
|
+ 553 : PTHREAD_RWLOCK_WRPHASE))))
|
||||||
|
+ 554 {
|
||||||
|
+ ...
|
||||||
|
+ 556 }
|
||||||
|
+
|
||||||
|
+ We clear PTHREAD_RWLOCK_WRLOCKED, and if there are
|
||||||
|
+ no readers so we leave the lock in PTHRAD_RWLOCK_WRPHASE.
|
||||||
|
+
|
||||||
|
+ Back in the read lock.
|
||||||
|
+
|
||||||
|
+ The read lock adjusts __readres as above.
|
||||||
|
+
|
||||||
|
+ 383 while ((r & PTHREAD_RWLOCK_WRPHASE) != 0
|
||||||
|
+ 384 && (r & PTHREAD_RWLOCK_WRLOCKED) == 0)
|
||||||
|
+ 385 {
|
||||||
|
+ ...
|
||||||
|
+ 390 if (atomic_compare_exchange_weak_acquire (&rwlock->__data.__readers, &r,
|
||||||
|
+ 391 r ^ PTHREAD_RWLOCK_WRPHASE))
|
||||||
|
+ 392 {
|
||||||
|
+
|
||||||
|
+ And then attemps to start the read phase.
|
||||||
|
+
|
||||||
|
+ Assume there happens to be a tryrdlock at this point, noting
|
||||||
|
+ that PTHREAD_RWLOCK_WRLOCKED is clear, and PTHREAD_RWLOCK_WRPHASE
|
||||||
|
+ is 1. So the try lock attemps to start the read phase.
|
||||||
|
+
|
||||||
|
+ In __pthread_rwlock_tryrdlock:
|
||||||
|
+
|
||||||
|
+ 44 if ((r & PTHREAD_RWLOCK_WRPHASE) == 0)
|
||||||
|
+ 45 {
|
||||||
|
+ ...
|
||||||
|
+ 49 if (((r & PTHREAD_RWLOCK_WRLOCKED) != 0)
|
||||||
|
+ 50 && (rwlock->__data.__flags
|

|
||||||
|
+ 90 &r, rnew));
|
||||||
|
+
|
||||||
|
+ And succeeds.
|
||||||
|
+
|
||||||
|
+ Back in the write unlock:
|
||||||
|
+
|
||||||
|
+ 557 if ((r >> PTHREAD_RWLOCK_READER_SHIFT) != 0)
|
||||||
|
+ 558 {

|

|
+ 565 futex_wake (&rwlock->__data.__wrphase_futex, INT_MAX, private);
|
||||||
|
+ 566 }
|
||||||
|
+
|
||||||
|
+ We note that PTHREAD_RWLOCK_FUTEX_USED is non-zero
|
||||||
|
+ and don't wake anyone. This is OK because we handed
|
||||||
|
+ over to the trylock. It will be the trylock's responsibility
|
||||||
|
+ to wake any waiters.
|
||||||
|
+
|
||||||
|
+ Back in the read lock:
|
||||||
|
+
|
||||||
|
+ The read lock fails to install PTHRAD_REWLOCK_WRPHASE as 0 because
|
||||||
|
+ the __readers value was adjusted by the trylock, and so it falls through
|
||||||
|
+ to waiting on the lock for explicit handover from either a new writer
|
||||||
|
+ or a new reader.
|
||||||
|
+
|
||||||
|
+ 448 int err = futex_abstimed_wait (&rwlock->__data.__wrphase_futex,
|
||||||
|
+ 449 1 | PTHREAD_RWLOCK_FUTEX_USED,
|
||||||
|
+ 450 abstime, private);
|
||||||
|
+
|
||||||
|
+ We use PTHREAD_RWLOCK_FUTEX_USED to indicate the futex
|
||||||
|
+ is in use.
|
||||||
|
+
|
||||||
|
+ At this point we have readers waiting on the read lock
|
||||||
|
+ to unlock. The wrlock is done. The trylock is finishing
|
||||||
|
+ the installation of the read phase.
|
||||||
|
+
|
||||||
|
+ 92 if ((r & PTHREAD_RWLOCK_WRPHASE) != 0)

||||||

|
+ ...
|
||||||
|
+ 105 atomic_store_relaxed (&rwlock->__data.__wrphase_futex, 0);
|
||||||
|
+ 106 }
|
||||||
|
+
|
||||||
|
+ The trylock does note that we were the one that
|
||||||
|
+ installed the read phase, but the comments are not
|
||||||
|
+ correct, the execution ordering above shows that
|
||||||
|
+ readers might indeed be waiting, and they are.
|
||||||
|
+
|
||||||
|
+ The atomic_store_relaxed throws away PTHREAD_RWLOCK_FUTEX_USED,
|
||||||
|
+ and the waiting reader is never worken becuase as noted
|
||||||
|
+ above it is conditional on the futex being used.
|
||||||
|
+
|
||||||
|
+ The solution is for the trylock thread to inspect
|
||||||
|
+ PTHREAD_RWLOCK_FUTEX_USED and wake the waiting readers.

+
|

|

+
|

|

|

|

|
||||||
|
+
|

|

|
+ taking a concurrent read lock, and thus we can safely write 1 to
|
||||||
|
+ __wrphase_futex.
|
||||||
|
+
|
||||||
|
+ If we did not install the write phase then the readers may already
|
||||||
|
+ be waiting on the futex, the original writer wrote 1 to __wrphase_futex
|
||||||

|

|
+ that PTHREAD_RWLOCK_FUTEX_USED is set in the __wrphase_futex futex
|
||||||
|
+ and then waking the futex.
|

|
+
|
||||||
|
+ The fix for bug 23844 ensures that waiters on __wrphase_futex are
|
||||||
|
+ correctly woken. Before the fix the test stalls as readers can
|
||||||
|
+ wait forever on __wrphase_futex. */

|
+ Summary for the pthread_rwlock_trywrlock() stall:
|
||||||
|
+
|
||||||
|
+ The stall is caused by pthread_rwlock_trywrlock setting
|
||||||
|
+ __wrphase_futex futex to 1 and loosing the
|
||||||
|
+ PTHREAD_RWLOCK_FUTEX_USED bit.
|
||||||
|
+
|
||||||
|
+ The fix for bug 23844 ensures that waiters on __wrphase_futex are
|
||||||
|
+ correctly woken. Before the fix the test stalls as readers can
|
||||||
|
+ wait forever on __wrphase_futex. */

S390: Remove s390 specific implementation of bcopy.
|
||||||
|
|
||||||
|
Nowadays gcc is automatically replacing a call to bcopy
|
||||||
|
with a call to memmove. Thus only old binaries will call
|
||||||
|
the s390 specific bcopy implementation.
|
||||||
|
|
||||||
|
The s390 specific implementation is using an own
|
||||||
|
implementation for memcpy in the forward case and is
|
||||||
|
relying on memmove in the backward case.
|
||||||
|
|
||||||
|
After removing the s390 specific bcopy, the common code
|
||||||
|
bcopy is used. It just performs a tail call to memmove.
|
||||||
|
|
||||||
|
ChangeLog:
|
||||||
|
* sysdeps/s390/s390-32/bcopy.S: Remove.
|
||||||
|
* sysdeps/s390/s390-64/bcopy.S: Likewise.

S390: Use memcpy for forward cases in memmove.
|

|

|
The s390/s390x memcpy implementations are safe to be

used by memmove. Starting with this commit, memmove is
|
||||||
|
using memcpy for the forward cases on s390.

S390: Add z13 memmove ifunc variant.
|
||||||
|
|
||||||
|
This patch introduces a z13 specific ifunc variant for memmove.
|
||||||
|
As the common code implementation, it checks if we can copy from
|
||||||
|
the beginning to the end - with z196 memcpy implementation - or
|
||||||
|
if we have to copy from the end to the beginning.
|
||||||
|
The latter case is done by using vector load/store instructions.
|
||||||
|
|
||||||
|
If vector instructions are not available, the common-code is
|
||||||
|
used as fallback. Therefore it is implemented in memmove-c with
|
||||||
|
a different name.
|
||||||
|
Furthermore the ifunc logic decides if we need the common-code
|
||||||
|
implementation at all. If vector instructions are supported
|
||||||
|
due to the minimum architecture level set we can skip the
|
||||||
|
common-code ifunc variant.
|
||||||
|
|
||||||
|
ChangeLog:
|
||||||
|
|
||||||
|
* sysdeps/s390/Makefile (sysdep_routines): Add memmove-c.
|
||||||
|
* sysdeps/s390/ifunc-memcpy.h (HAVE_MEMMOVE_IFUNC,
|
||||||
|
HAVE_MEMMOVE_IFUNC_AND_VX_SUPPORT, MEMMOVE_DEFAULT,
|
||||||
|
HAVE_MEMMOVE_C, MEMMOVE_C, HAVE_MEMMOVE_Z13, MEMMOVE_Z13):
|
||||||
|
New defines.
|
||||||
|
* sysdeps/s390/memcpy-z900.S: Add z13 memmove implementation.
|
||||||
|
* sysdeps/s390/memmove-c.c: New file.
|
||||||
|
* sysdeps/s390/memmove.c: Likewise.
|
||||||
|
* sysdeps/s390/multiarch/ifunc-impl-list.c
|
||||||
|
(__libc_ifunc_impl_list): Add ifunc variants for memmove.

S390: Add z13 strstr ifunc variant.
|
||||||
|
|

|
The new vector variant of strstr is using the common code
|

implementation, but instead of calling the default
|
||||||
|
str* / mem* functions, the vector variants are called.
|
||||||

S390: Refactor strlen ifunc handling.
|
||||||
|
|
||||||
|
The ifunc handling for strlen is adjusted in order to omit ifunc
|
||||||
|
variants if those will never be used as the minimum architecture level
|
||||||
|
already supports newer CPUs by default.
|
||||||
|
Glibc internal calls will then also use the "newer" ifunc variant.
|
||||||
|
|
||||||
|
ChangeLog:
|
||||||
|
|
||||||
|
* sysdeps/s390/multiarch/Makefile
|
||||||
|
(sysdep_routines): Remove strlen variants.
|
||||||
|
* sysdeps/s390/Makefile (sysdep_routines): Add strlen variants.
|
||||||
|
* sysdeps/s390/multiarch/ifunc-impl-list.c
|
||||||
|
(__libc_ifunc_impl_list): Refactor ifunc handling for strlen.
|
||||||
|
* sysdeps/s390/multiarch/strlen-c.c: Move to ...
|
||||||
|
* sysdeps/s390/strlen-c.c: ... here and adjust ifunc handling.
|
||||||
|
* sysdeps/s390/multiarch/strlen-vx.S: Move to ...
|
||||||
|
* sysdeps/s390/strlen-vx.S: ... here and adjust ifunc handling.
|
||||||
|
* sysdeps/s390/multiarch/strlen.c: Move to ...
|
||||||
|
* sysdeps/s390/strlen.c: ... here and adjust ifunc handling.
|
||||||
|
* sysdeps/s390/ifunc-strlen.h: New file.

S390: Refactor strnlen ifunc handling.
|
||||||
|
|
||||||
|
The ifunc handling for strnlen is adjusted in order to omit ifunc
|
||||||
|
variants if those will never be used as the minimum architecture level
|
||||||
|
already supports newer CPUs by default.
|
||||||
|
Glibc internal calls will then also use the "newer" ifunc variant.
|
||||||
|
|
||||||
|
ChangeLog:
|
||||||
|
|
||||||
|
* sysdeps/s390/multiarch/Makefile
|
||||||
|
(sysdep_routines): Remove strnlen variants.
|
||||||
|
* sysdeps/s390/Makefile (sysdep_routines): Add strnlen variants.
|
||||||
|
* sysdeps/s390/multiarch/ifunc-impl-list.c
|
||||||
|
(__libc_ifunc_impl_list): Refactor ifunc handling for strnlen.
|
||||||
|
* sysdeps/s390/multiarch/strnlen-c.c: Move to ...
|
||||||
|
* sysdeps/s390/strnlen-c.c: ... here and adjust ifunc handling.
|
||||||
|
* sysdeps/s390/multiarch/strnlen-vx.S: Move to ...
|
||||||
|
* sysdeps/s390/strnlen-vx.S: ... here and adjust ifunc handling.
|
||||||
|
* sysdeps/s390/multiarch/strnlen.c: Move to ...
|
||||||
|
* sysdeps/s390/strnlen.c: ... here and adjust ifunc handling.
|
||||||
|
* sysdeps/s390/ifunc-strnlen.h: New file.

S390: Refactor strcpy ifunc handling.
|
||||||
|
|
||||||
|
The ifunc handling for strcpy is adjusted in order to omit ifunc
|
||||||
|
variants if those will never be used as the minimum architecture level
|
||||||
|
already supports newer CPUs by default.
|
||||||
|
Glibc internal calls will then also use the "newer" ifunc variant.
|
||||||
|
|
||||||
|
Note: The fallback s390-32/s390-64 ifunc variants with mvst instruction
|
||||||
|
are now moved to the unified strcpy-z900.S file which can be used for
|
||||||
|
31/64bit. The s390-32/s390-64 files multiarch/strcpy.c and strcpy.S
|
||||||
|
are deleted.
|
||||||
|
|
||||||
|
ChangeLog:
|
||||||
|
|
||||||
|
* sysdeps/s390/multiarch/Makefile
|
||||||
|
(sysdep_routines): Remove strcpy variants.
|
||||||
|
* sysdeps/s390/Makefile (sysdep_routines): Add strcpy variants.
|
||||||
|
* sysdeps/s390/multiarch/ifunc-impl-list.c
|
||||||
|
(__libc_ifunc_impl_list): Refactor ifunc handling for strcpy.
|
||||||
|
* sysdeps/s390/multiarch/strcpy-vx.S: Move to ...
|
||||||
|
* sysdeps/s390/strcpy-vx.S: ... here and adjust ifunc handling.
|
||||||
|
* sysdeps/s390/multiarch/strcpy.c: Move to ...
|
||||||
|
* sysdeps/s390/strcpy.c: ... here and adjust ifunc handling.
|
||||||
|
* sysdeps/s390/ifunc-strcpy.h: New file.
|
||||||
|
* sysdeps/s390/s390-64/strcpy.S: Move to ...
|
||||||
|
* sysdeps/s390/strcpy-z900.S: ... here and adjust to be usable
|
||||||
|
for 31/64bit and ifunc handling.
|
||||||
|
* sysdeps/s390/s390-32/multiarch/strcpy.c: Delete file.
|
||||||
|
* sysdeps/s390/s390-64/multiarch/strcpy.c: Likewise.
|
||||||
|
* sysdeps/s390/s390-32/strcpy.S: Likewise.

commit 970449311ded3cacb6058c96143dd4c057900589

S390: Refactor stpcpy ifunc handling.
|
||||||
|
|
||||||
|
The ifunc handling for stpcpy is adjusted in order to omit ifunc
|
||||||
|
variants if those will never be used as the minimum architecture level
|
||||||
|
already supports newer CPUs by default.
|
||||||
|
Glibc internal calls will then also use the "newer" ifunc variant.
|
||||||
|
|
||||||
|
ChangeLog:
|
||||||
|
|
||||||
|
* sysdeps/s390/multiarch/Makefile
|
||||||
|
(sysdep_routines): Remove stpcpy variants.
|
||||||
|
* sysdeps/s390/Makefile (sysdep_routines): Add stpcpy variants.
|
||||||
|
* sysdeps/s390/multiarch/ifunc-impl-list.c
|
||||||
|
(__libc_ifunc_impl_list): Refactor ifunc handling for stpcpy.
|
||||||
|
* sysdeps/s390/multiarch/stpcpy-c.c: Move to ...
|
||||||
|
* sysdeps/s390/stpcpy-c.c: ... here and adjust ifunc handling.
|
||||||
|
* sysdeps/s390/multiarch/stpcpy-vx.S: Move to ...
|
||||||
|
* sysdeps/s390/stpcpy-vx.S: ... here and adjust ifunc handling.
|
||||||
|
* sysdeps/s390/multiarch/stpcpy.c: Move to ...
|
||||||
|
* sysdeps/s390/stpcpy.c: ... here and adjust ifunc handling.
|
||||||
|
* sysdeps/s390/ifunc-stpcpy.h: New file.

S390: Use hwcap instead of dl_hwcap in ifunc-resolvers.
|
||||||
|
|
||||||
|
The renaming of hwcap arguments in ifunc-resolvers is needed
|
||||||
|
in order to prepare for further commits which refactors
|
||||||
|
ifunc handling for memset, memcmp, and memcpy. Now you are able
|
||||||
|
to use s390_libc_ifunc_init which stores the stfle bits
|
||||||
|
within the expression for an ifunc-resolver generated by
|
||||||
|
s390_libc_ifunc_expr.
|
||||||
|
|
||||||
|
ChangeLog:
|
||||||
|
|
||||||
|
* sysdeps/s390/multiarch/ifunc-resolve.h
|
||||||
|
(s390_libc_ifunc_init, s390_libc_ifunc,
|
||||||
|
s390_vx_libc_ifunc2_redirected): Use hwcap instead of dl_hwcap.
