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\

Makeconfig (ASFLAGS): Always append required assembler flags.
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.

commit f5117c6504888fab5423282a4607c552b90fd3f9
Author: Carlos O'Donell <carlos@redhat.com>
Date: Thu Jul 29 22:45:39 2021 -0400
Add 'codepoint_collation' support for LC_COLLATE.
Support a new directive 'codepoint_collation' in the LC_COLLATE
section of a locale source file. This new directive causes all
collation rules to be dropped and instead STRCMP (strcmp or
wcscmp) is used for collation of the input character set. This
is required to allow for a C.UTF-8 that contains zero collation
rules (minimal size) and sorts using code point sorting.
To date the only implementation of a locale with zero collation
rules is the C/POSIX locale. The C/POSIX locale provides
identity tables for _NL_COLLATE_COLLSEQMB and
_NL_COLLATE_COLLSEQWC that map to ASCII even though it has zero
rules. This has lead to existing fnmatch, regexec, and regcomp
implementations that require these tables. It is not correct
to use these tables when nrules == 0, but the conservative fix
is to provide these tables when nrules == 0. This assures that
existing static applications using a new C.UTF-8 locale with
'codepoint_collation' at least have functional range expressions
with ASCII e.g. [0-9] or [a-z]. Such static applications would
not have the fixes to fnmatch, regexec and regcomp that avoid
the use of the tables when nrules == 0. Future fixes to fnmatch,
regexec, and regcomp would allow range expressions to use the
full set of code points for such ranges.
Tested on x86_64 and i686 without regression.

commit 1d8e3a2c6636cf0b1b8fa2f869cef6ec10726933
Author: Carlos O'Donell <carlos@redhat.com>
Date: Mon Jan 31 00:34:41 2022 -0500
localedef: Fix handling of empty mon_decimal_point (Bug 28847)
The handling of mon_decimal_point is incorrect when it comes to
handling the empty "" value. The existing parser in monetary_read()
will correctly handle setting the non-wide-character value and the
wide-character value e.g. STR_ELEM_WC(mon_decimal_point) if they are
set in the locale definition. However, in monetary_finish() we have
conflicting TEST_ELEM() which sets a default value (if the locale
definition doesn't include one), and subsequent code which looks for
mon_decimal_point to be NULL to issue a specific error message and set
the defaults. The latter is unused because TEST_ELEM() always sets a
default. The simplest solution is to remove the TEST_ELEM() check,
and allow the existing check to look to see if mon_decimal_point is
NULL and set an appropriate default. The final fix is to move the
setting of mon_decimal_point_wc so it occurs only when
mon_decimal_point is being set to a default, keeping both values
consistent. There is no way to tell the difference between
mon_decimal_point_wc having been set to the empty string and not
having been defined at all, for that distinction we must use
mon_decimal_point being NULL or "", and so we must logically set
the default together with mon_decimal_point.
Lastly, there are more fixes similar to this that could be made to
ld-monetary.c, but we avoid that in order to fix just the code
required for mon_decimal_point, which impacts the ability for C.UTF-8
to set mon_decimal_point to "", since without this fix we end up with
an inconsistent setting of mon_decimal_point set to "", but
mon_decimal_point_wc set to "." which is incorrect.
Tested on x86_64 and i686 without regression.

commit de82cb0da4b8fa5b3d56c457438d2568c67ab1b1
Author: Joseph Myers <joseph@codesourcery.com>
Date: Tue Oct 12 13:48:39 2021 +0000
Add TEST_COMPARE_STRING_WIDE to support/check.h
I'd like to be able to test narrow and wide string interfaces, with
the narrow string tests using TEST_COMPARE_STRING and the wide string
tests using something analogous (possibly generated using macros from
a common test template for both the narrow and wide string tests where
appropriate).
Add such a TEST_COMPARE_STRING_WIDE, along with functions
support_quote_blob_wide and support_test_compare_string_wide that it
builds on. Those functions are built using macros from common
templates shared by the narrow and wide string implementations, though
I didn't do that for the tests of test functions. In
support_quote_blob_wide, I chose to use the \x{} delimited escape
sequence syntax proposed for C2X in N2785, rather than e.g. trying to
generate the end of a string and the start of a new string when
ambiguity would result from undelimited \x (when the next character
after such an escape sequence is valid hex) or forcing an escape
sequence to be used for the next character in the case of such
ambiguity.
Tested for x86_64.

commit 7e0ad15c0fbfe25435c1acd0ed3e9cedfbff2488
Author: Carlos O'Donell <carlos@redhat.com>
Date: Mon Jan 31 00:34:42 2022 -0500
localedata: Adjust C.UTF-8 to align with C/POSIX.
We have had one downstream report from Canonical [1] that
an rrdtool test was broken by the differences in LC_TIME
that we had in the non-builtin C locale (C.UTF-8). If one
application has an issue there are going to be others, and
so with this commit we review and fix all the issues that
cause the builtin C locale to be different from C.UTF-8,
which includes:
* mon_decimal_point should be empty e.g. ""
- Depends on mon_decimal_point_wc fix.
* negative_sign should be empty e.g. ""
* week should be aligned with the builtin C/POSIX locale
* d_fmt corrected with escaped slashes e.g. "%m//%d//%y"
* yesstr and nostr should be empty e.g. ""
* country_ab2 and country_ab3 should be empty e.g. ""
We bump LC_IDENTIFICATION version and adjust the date to
indicate the change in the locale.
A new tst-c-utf8-consistency test is added to ensure
consistency between C/POSIX and C.UTF-8.
Tested on x86_64 and i686 without regression.

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.

Short description: Adjust CS_PATH return value.
Short description: Adjust CS_PATH and the test container layout.
Author(s): Fedora glibc team <glibc@lists.fedoraproject.org>

Upstream status: not-needed
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).

We also create /{bin,lib,lib64,sbin} in the test container as symbolic
links. This brings the test container in line with Fedora's filesystem
layout and avoids some test failures. For example, because Fedora's
CS_PATH is /usr/bin, tst-vfork3 will try to execute /usr/bin/echo in the
container. Without this change the container installs `echo' in /bin
not /usr/bin, causing the test to fail.

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 enabling batch read in NSS.

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.

support: Add signal support to support_capture_subprocess_check
Signal zero does not terminate a process, so it is safe to use negative
values for signal numbers.
Adjust libio/tst-vtables-common.c to use this new functionality,
instead of determining the termination status for a signal indirectly.

This reverts the non-test change from commit d0093c5cefb7f7a4143f

the underlying bug has been fixed properly in commit 61b74477fa7f63

[BZ #20839]").
Tested on x86-64-linux-gnu, with and without --enable-cet.

commit f8ed116aa574435c6e28260f21963233682d3b57
Author: Florian Weimer <fweimer@redhat.com>
Date: Fri Dec 13 10:18:46 2019 +0100
dlopen: Rework handling of pending NODELETE status
Commit a2e8aa0d9ea648068d8be52dd7b15f1b6a008e23 ("Block signals during
the initial part of dlopen") was deemed necessary because of
read-modify-write operations like the one in add_dependency in
elf/dl-lookup.c. In the old code, we check for any kind of NODELETE
status and bail out:
/* Redo the NODELETE check, as when dl_load_lock wasn't held
yet this could have changed. */
if (map->l_nodelete != link_map_nodelete_inactive)
goto out;
And then set pending status (during relocation):
if (flags & DL_LOOKUP_FOR_RELOCATE)
map->l_nodelete = link_map_nodelete_pending;
else
map->l_nodelete = link_map_nodelete_active;
If a signal arrives during relocation and the signal handler, through
lazy binding, adds a global scope dependency on the same map, it will
set map->l_nodelete to link_map_nodelete_active. This will be
overwritten with link_map_nodelete_pending by the dlopen relocation
code.
To avoid such problems in relation to the l_nodelete member, this
commit introduces two flags for active NODELETE status (irrevocable)
and pending NODELETE status (revocable until activate_nodelete is
invoked). As a result, NODELETE processing in dlopen does not
introduce further reasons why lazy binding from signal handlers
is unsafe during dlopen, and a subsequent commit can remove signal
blocking from dlopen.
This does not address pre-existing issues (unrelated to the NODELETE
changes) which make lazy binding in a signal handler during dlopen
unsafe, such as the use of malloc in both cases.

commit f7649d5780aa4682393b9daedd653e4d9c12784c
Author: Florian Weimer <fweimer@redhat.com>
Date: Fri Dec 13 10:23:10 2019 +0100
dlopen: Do not block signals
Blocking signals causes issues with certain anti-malware solutions
which rely on an unblocked SIGSYS signal for system calls they
intercept.
This reverts commit a2e8aa0d9ea648068d8be52dd7b15f1b6a008e23
("Block signals during the initial part of dlopen") and adds
comments related to async signal safety to active_nodelete and
its caller.
Note that this does not make lazy binding async-signal-safe with regards
to dlopen. It merely avoids introducing new async-signal-safety hazards
as part of the NODELETE changes.

elf: Add elf/tst-dlopenfail-2 [BZ #25396]
Without CET, a jump into a newly loaded object through an overwritten
link map often does not crash, it just executes some random code.
CET detects this in some cases because the function pointer does not
point to the start of a function in the replacement shared object,
so there is no ENDBR instruction.
The new test uses a small shared object and the existing dangling
link map to trigger the bug.

Enhance _dl_catch_exception to allow disabling exception handling
In some cases, it is necessary to introduce noexcept regions
where raised dynamic loader exceptions (e.g., from lazy binding)
are fatal, despite being nested in a code region with an active
exception handler. This change enhances _dl_catch_exception with
to provide such a capability. The existing function is reused,
so that it is not necessary to introduce yet another function with
a similar purpose.

Introduce DL_LOOKUP_FOR_RELOCATE flag for _dl_lookup_symbol_x
This will allow changes in dependency processing during non-lazy
binding, for more precise processing of NODELETE objects: During
initial relocation in dlopen, the fate of NODELETE objects is still
unclear, so objects which are depended upon by NODELETE objects
cannot immediately be marked as NODELETE.

commit 79e0cd7b3c997e211fad44a81fd839dc5b2546e8
Author: Florian Weimer <fweimer@redhat.com>
Date: Wed Nov 27 16:20:47 2019 +0100
Lazy binding failures during dlopen/dlclose must be fatal [BZ #24304]
If a lazy binding failure happens during the execution of an ELF
constructor or destructor, the dynamic loader catches the error
and reports it using the dlerror mechanism. This is undesirable
because there could be other constructors and destructors that
need processing (which are skipped), and the process is in an
inconsistent state at this point. Therefore, we have to issue
a fatal dynamic loader error error and terminate the process.
Note that the _dl_catch_exception in _dl_open is just an inner catch,
to roll back some state locally. If called from dlopen, there is
still an outer catch, which is why calling _dl_init via call_dl_init
and a no-exception is required and cannot be avoiding by moving the
_dl_init call directly into _dl_open.
_dl_fini does not need changes because it does not install an error
handler, so errors are already fatal there.

Avoid late failure in dlopen in global scope update [BZ #25112]
The call to add_to_global in dl_open_worker happens after running ELF
constructors for new objects. At this point, proper recovery from
malloc failure would be quite complicated: We would have to run the
ELF destructors and close all opened objects, something that we
currently do not do.
Instead, this change splits add_to_global into two phases,
add_to_global_resize (which can raise an exception, called before ELF
constructors run), and add_to_global_update (which cannot, called
after ELF constructors). A complication arises due to recursive
dlopen: After the inner dlopen consumes some space, the pre-allocation
in the outer dlopen may no longer be sufficient. A new member in the
namespace structure, _ns_global_scope_pending_adds keeps track of the
maximum number of objects that need to be added to the global scope.
This enables the inner add_to_global_resize call to take into account
the needs of an outer dlopen.
Most code in the dynamic linker assumes that the number of global
scope entries fits into an unsigned int (matching the r_nlist member
of struct r_scop_elem). Therefore, change the type of
_ns_global_scope_alloc to unsigned int (from size_t), and add overflow
checks.

commit a509eb117fac1d764b15eba64993f4bdb63d7f3c
Author: Florian Weimer <fweimer@redhat.com>
Date: Wed Nov 27 16:37:17 2019 +0100
Avoid late dlopen failure due to scope, TLS slotinfo updates [BZ #25112]
This change splits the scope and TLS slotinfo updates in dlopen into
two parts: one to resize the data structures, and one to actually apply
the update. The call to add_to_global_resize in dl_open_worker is moved
before the demarcation point at which no further memory allocations are
allowed.
_dl_add_to_slotinfo is adjusted to make the list update optional. There
is some optimization possibility here because we could grow the slotinfo
list of arrays in a single call, one the largest TLS modid is known.
This commit does not fix the fatal meory allocation failure in
_dl_update_slotinfo. Ideally, this error during dlopen should be
recoverable.
The update order of scopes and TLS data structures is retained, although
it appears to be more correct to fully initialize TLS first, and then
expose symbols in the newly loaded objects via the scope update.
Tested on x86_64-linux-gnu.

Remove all loaded objects if dlopen fails, ignoring NODELETE [BZ #20839]
This introduces a “pending NODELETE” state in the link map, which is
flipped to the persistent NODELETE state late in dlopen, via
activate_nodelete. During initial relocation, symbol binding
records pending NODELETE state only. dlclose ignores pending NODELETE
state. Taken together, this results that a partially completed dlopen
is rolled back completely because new NODELETE mappings are unloaded.
Tested on x86_64-linux-gnu and i386-linux-gnu.

commit a2e8aa0d9ea648068d8be52dd7b15f1b6a008e23
Author: Florian Weimer <fweimer@redhat.com>
Date: Thu Oct 31 19:30:19 2019 +0100
Block signals during the initial part of dlopen
Lazy binding in a signal handler that interrupts a dlopen sees
intermediate dynamic linker state. This has likely been always
unsafe, but with the new pending NODELETE state, this is clearly
incorrect. Other threads are excluded via the loader lock, but the
current thread is not. Blocking signals until right before ELF

commit 4b25485f03158959cff45379eecc1d73c7dcdd11
Author: Florian Weimer <fweimer@redhat.com>
Date: Fri Aug 10 11:19:26 2018 +0200
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.

commit d524fa6c35e675eedbd8fe6cdf4db0b49c658026
Author: H.J. Lu <hjl.tools@gmail.com>
Date: Thu Nov 8 10:06:58 2018 -0800
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]
* sysdeps/x86/dl-prop.h (_dl_process_cet_property_note): Skip
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.
* sysdeps/x86/link_map.h (l_cet): Expand to 3 bits, Add
lc_unknown.

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.

Add XFAIL_ROUNDING_IBM128_LIBGCC to more fma() tests
Ignore 16 errors in math/test-ldouble-fma and 4 errors in
math/test-ildouble-fma when IBM 128-bit long double used.
These errors are caused by spurious overflows from libgcc.

commit 0ef2f4400c06927af34c515555f68840a70ba409
Author: Wilco Dijkstra <wdijkstr@arm.com>
Date: Wed Sep 19 16:50:18 2018 +0100
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.

commit e5d262effe3a87164308a3f37e61b32d0348692a
Author: Tulio Magno Quites Machado Filho <tuliom@linux.ibm.com>
Date: Fri Nov 30 18:05:32 2018 -0200
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]
* elf/dl-runtime.c (_dl_profile_fixup): Guarantee memory
modification order when accessing reloc_result->addr.
* include/link.h (reloc_result): Add field init.
* nptl/Makefile (tests): Add tst-audit-threads.
(modules-names): Add tst-audit-threads-mod1 and
tst-audit-threads-mod2.
Add rules to build tst-audit-threads.
* nptl/tst-audit-threads-mod1.c: New file.
* nptl/tst-audit-threads-mod2.c: Likewise.

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
Author: Stefan Liebler <stli@linux.ibm.com>
Date: Thu Aug 30 08:44:32 2018 +0200
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.
Reviewed-by: Carlos O'Donell <carlos@redhat.com>
ChangeLog:
* stdlib/test-bz22786.c (do_test): Return EXIT_UNSUPPORTED
if malloc fails.

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.

commit a8ff215e56050a907189e713fd449bcafe99ff6b
Author: Florian Weimer <fweimer@redhat.com>

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.

elf: Link sotruss-lib.so with BIND_NOW for --enable-bind-now
The audit module itself can be linked with BIND_NOW; it does not
affect its functionality.

commit c3d8dc45c9df199b8334599a6cbd98c9950dba62

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.
[BZ #23709]
* sysdeps/x86/cpu-features.c (init_cpu_features): Set TSX bits
independently of other flags.

powerpc64: Add memory protection key support [BZ #23202]
The 32-bit protection key behavior is somewhat unclear on 32-bit powerpc,
so this change is restricted to the 64-bit variants.
Flag translation is needed because of hardware differences between the
POWER implementation (read and write flags) and the Intel implementation
(write and read+write flags).

Fix tst-pkey expectations on pkey_get [BZ #23202]
From the GNU C Library manual, the pkey_set can receive a combination of
PKEY_DISABLE_WRITE and PKEY_DISABLE_ACCESS. However PKEY_DISABLE_ACCESS
is more restrictive than PKEY_DISABLE_WRITE and includes its behavior.
The test expects that after setting
(PKEY_DISABLE_WRITE|PKEY_DISABLE_ACCESS) pkey_get should return the
same. This may not be true as PKEY_DISABLE_ACCESS will succeed in
describing the state of the key in this case.
The pkey behavior during signal handling is different between x86 and
POWER. This change make the test compatible with both architectures.

Fix tst-pkey.c pkey_alloc return checks and manual
This test was failing in some powerpc systems as it was not checking
for ENOSPC return.
As said on the Linux man-pages and can be observed by the implementation
at mm/mprotect.c in the Linux Kernel source. The syscall pkey_alloc can
return EINVAL or ENOSPC. ENOSPC will indicate either that all keys are
in use or that the kernel does not support pkeys.

POWER: Add context-synchronizing instructions to pkey_write [BZ #25954]
Sandipan Das reported that,
"The Power ISA mandates that all writes to the Authority
Mask Register (AMR) must always be preceded as well as
succeeded by a context-synchronizing instruction. This
applies to both the privileged and unprivileged variants
of the Move To AMR instruction.
This [requirement] is from Table 6 of Chapter 11 in page 1134 of Power
ISA 3.0B. The document can be found here:
<https://ibm.ent.box.com/s/1hzcwkwf8rbju5h9iyf44wm94amnlcrv>

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.
[BZ #23579]
* misc/tst-preadvwritev2-common.c (do_test_with_invalid_fd): New
test.
* misc/tst-preadvwritev2.c, misc/tst-preadvwritev64v2.c (do_test):

* sysdeps/unix/sysv/linux/preadv2.c (preadv2): Use fallback code iff

enabled by kernel.
Tested on i686 with and without --enable-cet as well as on CET emulator
with --enable-cet.

commit 403b4feb22dcbc85ace72a361d2a951380372471
Author: Stefan Liebler <stli@linux.ibm.com>
Date: Wed Oct 17 12:23:04 2018 +0200
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):
Ensure that elision path is used if elision is available.
* sysdeps/unix/sysv/linux/powerpc/force-elision.h (FORCE_ELISION):
Likewise.
* sysdeps/unix/sysv/linux/x86/force-elision.h: (FORCE_ELISION):
Likewise.
* nptl/pthreadP.h (PTHREAD_MUTEX_TYPE, PTHREAD_MUTEX_TYPE_ELISION)
(PTHREAD_MUTEX_PSHARED): Use atomic_load_relaxed.
* nptl/pthread_mutex_consistent.c (pthread_mutex_consistent): Likewise.
* nptl/pthread_mutex_getprioceiling.c (pthread_mutex_getprioceiling):
Likewise.
* nptl/pthread_mutex_lock.c (__pthread_mutex_lock_full)
(__pthread_mutex_cond_lock_adjust): Likewise.
* nptl/pthread_mutex_setprioceiling.c (pthread_mutex_setprioceiling):
Likewise.
* nptl/pthread_mutex_timedlock.c (__pthread_mutex_timedlock): Likewise.
* nptl/pthread_mutex_trylock.c (__pthread_mutex_trylock): Likewise.
* nptl/pthread_mutex_unlock.c (__pthread_mutex_unlock_full): Likewise.
* sysdeps/nptl/bits/thread-shared-types.h (struct __pthread_mutex_s):
Add comments.
* nptl/pthread_mutex_destroy.c (__pthread_mutex_destroy):
Use atomic_load_relaxed and atomic_store_relaxed.
* nptl/pthread_mutex_init.c (__pthread_mutex_init):
Use atomic_store_relaxed.

+ binary compatibility with static initializers.
+
+ Concurrency notes:
+ The __kind of a mutex is initialized either by the static
+ PTHREAD_MUTEX_INITIALIZER or by a call to pthread_mutex_init.
+
+ After a mutex has been initialized, the __kind of a mutex is usually not
+ changed. BUT it can be set to -1 in pthread_mutex_destroy or elision can
+ be enabled. This is done concurrently in the pthread_mutex_*lock functions
+ by using the macro FORCE_ELISION. This macro is only defined for
+ architectures which supports lock 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
+ the lock / unlock functions are using specific elision code-paths. */

commit 17b26500f9bb926d85e86821d014f7c1bb88043c
Author: Joseph Myers <joseph@codesourcery.com>
Date: Mon Aug 13 21:35:27 2018 +0000
Update syscall-names.list for Linux 4.18.
This patch updates sysdeps/unix/sysv/linux/syscall-names.list for
Linux 4.18. The io_pgetevents and rseq syscalls are added to the
kernel on various architectures, so need to be mentioned in this file.
Tested with build-many-glibcs.py.
* sysdeps/unix/sysv/linux/syscall-names.list: Update kernel
version to 4.18.
(io_pgetevents): New syscall.
(rseq): Likewise.

Date: Mon Oct 22 23:26:37 2018 +0000
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.
Thanks,
Istvan

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.

commit f0458cf4f9ff3d870c43b624e6dccaaf657d5e83

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).
* NEWS: Add note about new TLE support on powerpc64le.
* sysdeps/powerpc/nptl/tcb-offsets.sym (TM_CAPABLE): Remove.
* sysdeps/powerpc/nptl/tls.h (tcbhead_t): Rename tm_capable to
__ununsed1.
(TLS_INIT_TP, TLS_DEFINE_INIT_TP): Remove tm_capable setup.
(THREAD_GET_TM_CAPABLE, THREAD_SET_TM_CAPABLE): Remove macros.
* sysdeps/powerpc/powerpc32/sysdep.h,
sysdeps/powerpc/powerpc64/sysdep.h (ABORT_TRANSACTION_IMPL,
ABORT_TRANSACTION): Remove macros.
* sysdeps/powerpc/sysdep.h (ABORT_TRANSACTION): Likewise.
* sysdeps/unix/sysv/linux/powerpc/elision-conf.c (elision_init): Set
__pthread_force_elision iff PPC_FEATURE2_HTM_NOSC is set.
* sysdeps/unix/sysv/linux/powerpc/powerpc32/sysdep.h,
sysdeps/unix/sysv/linux/powerpc/powerpc64/sysdep.h
sysdeps/unix/sysv/linux/powerpc/syscall.S (ABORT_TRANSACTION): Remove
usage.
* sysdeps/unix/sysv/linux/powerpc/not-errno.h: Remove file.
