stdio: Clean up __libc_message after unconditional abort
|
||||
|
||||
Since commit ec2c1fcefb200c6cb7e09553f3c6af8815013d83 ("malloc:
|
||||
Abort on heap corruption, without a backtrace [BZ #21754]"),
|
||||
__libc_message always terminates the process. Since commit
|
||||
a289ea09ea843ced6e5277c2f2e63c357bc7f9a3 ("Do not print backtraces
|
||||
on fatal glibc errors"), the backtrace facility has been removed.
|
||||
Therefore, remove enum __libc_message_action and the action
|
||||
argument of __libc_message, and mark __libc_message as _No_return.

nptl: Remove uses of assert_perror

__pthread_sigmask cannot actually fail with valid pointer arguments

(it would need a really broken seccomp filter), and we do not check

assert: Do not use stderr in libc-internal assert
|
||||
|
||||
Redirect internal assertion failures to __libc_assert_fail, based on
|
||||
based on __libc_message, which writes directly to STDERR_FILENO
|
||||
and calls abort. Also disable message translation and reword the
|
||||
error message slightly (adjusting stdlib/tst-bz20544 accordingly).
|
||||
|
||||
As a result of these changes, malloc no longer needs its own
|
||||
redefinition of __assert_fail.
|
||||
|
||||
__libc_assert_fail needs to be stubbed out during rtld dependency
|
||||
analysis because the rtld rebuilds turn __libc_assert_fail into
|
||||
__assert_fail, which is unconditionally provided by elf/dl-minimal.c.
|
||||
|
||||
This change is not possible for the public assert macro and its
|
||||
__assert_fail function because POSIX requires that the diagnostic
|
||||
is written to stderr.

Linux: Remove exit system call from _exit

|

exit only terminates the current thread, not the whole process, so it

is the wrong fallback system call in this context. All supported

Linux versions implement the exit_group system call anyway.

stdlib: Add arc4random, arc4random_buf, and arc4random_uniform (BZ #4417)

malloc: Do not clobber errno on __getrandom_nocancel (BZ #29624)
|
||||
|
||||
Use INTERNAL_SYSCALL_CALL instead of INLINE_SYSCALL_CALL. This
|
||||
requires emulate the semantic for hurd call (so __arc4random_buf
|
||||
uses the fallback).
|
||||
|
||||
Checked on x86_64-linux-gnu.

malloc: Use __getrandom_nocancel during tcache initiailization
|
||||
|
||||
Cancellation currently cannot happen at this point because dlopen
|
||||
as used by the unwind link always performs additional allocations
|
||||
for libgcc_s.so.1, even if it has been loaded already as a dependency
|
||||
of the main executable. But it seems prudent not to rely on this
|

quirk.

elf: Run tst-audit-tlsdesc, tst-audit-tlsdesc-dlopen everywhere
|
||||
|
||||
The test is valid for all TLS models, but we want to make a reasonable
|
||||
effort to test the GNU2 model specifically. For example, aarch64
|
||||
defaults to GNU2, but does not have -mtls-dialect=gnu2, and the test
|

was not run there.

elf: Implement force_first handling in _dl_sort_maps_dfs (bug 28937)
|
||||
|
||||
The implementation in _dl_close_worker requires that the first
|
||||
element of l_initfini is always this very map (“We are always the
|
||||
zeroth entry, and since we don't include ourselves in the
|
||||
dependency analysis start at 1.”). Rather than fixing that
|
||||
assumption, this commit adds an implementation of the force_first
|
||||
argument to the new dependency sorting algorithm. This also means
|
||||
that the directly dlopen'ed shared object is always initialized last,
|
||||
which is the least surprising behavior in the presence of cycles.

nss_dns: Rewrite _nss_dns_gethostbyname4_r using current interfaces
|
||||
|
||||
Introduce struct alloc_buffer to this function, and use it and
|

struct ns_rr_cursor in gaih_getanswer_slice. Adjust gaih_getanswer
|

and gaih_getanswer_noaaaa accordingly.

Maintain an explicit order of tunables, so that the tunable_list
|
||||
array and the tunable_id_t constant can remain consistent over time.
|
||||
|
||||
Related to this upstream bug:
|
||||
|
||||
Internal tunables ABI depends on awk array iteration order
|
||||
<https://sourceware.org/bugzilla/show_bug.cgi?id=30027>
|
||||
|
||||
The new dl-tunables.list files are already on the sysdeps search
|
||||
path, which is why the existing Makeconfig rule picks them up.
|
||||
The files for RHEL 9.1z were created by applying the gen-tunables.awk
|
||||
part of this patch to RHEL 9.1.0 (glibc-2.34-40.el9_2.1, to be
|
||||
precise). The sysdeps/unix/sysv/linux/**/dl-tunables.list files were
|
||||
created based on the generated error message during the RHEL 9.1.z
|
||||
build.
|
||||
|
||||
Going forward, new tunables will have to be added manually to the end
|
||||
of those files. Existing tunables should not be deleted. For
|
||||
deletion, the script would have to be extended to be able to create
|
||||
gaps in the tunable_list array.

Update syscall lists for Linux 5.19
|
||||
|
||||
Linux 5.19 has no new syscalls, but enables memfd_secret in the uapi
|
||||
headers for RISC-V. Update the version number in syscall-names.list
|
||||
to reflect that it is still current for 5.19 and regenerate the
|
||||
arch-syscall.h headers with build-many-glibcs.py update-syscalls.
|
||||
|
||||
Tested with build-many-glibcs.py.

stdlib: Remove attr_write from mbstows if dst is NULL [BZ: 29265]
|
||||
|
||||
Incorrectly called `__mbstowcs_chk` in the NULL __dst case which is
|
||||
incorrect as in the NULL __dst case we are explicitly skipping
|
||||
the objsize checks.
|
||||
|
||||
As well, remove the `__always_inline` attribute which exists in
|
||||
`__fortify_function`.

alpha: Fix generic brk system call emulation in __brk_call (bug 29490)
|
||||
|
||||
The kernel special-cases the zero argument for alpha brk, and we can
|
||||
use that to restore the generic Linux error handling behavior.
|
||||
|
||||
Fixes commit b57ab258c1140bc45464b4b9908713e3e0ee35aa ("Linux:
|
||||
Introduce __brk_call for invoking the brk system call").

socket: Check lengths before advancing pointer in CMSG_NXTHDR
|
||||
|
||||
The inline and library functions that the CMSG_NXTHDR macro may expand
|
||||
to increment the pointer to the header before checking the stride of
|
||||
the increment against available space. Since C only allows incrementing
|
||||
pointers to one past the end of an array, the increment must be done
|
||||
after a length check. This commit fixes that and includes a regression
|
||||
test for CMSG_FIRSTHDR and CMSG_NXTHDR.
|
||||
|
||||
The Linux, Hurd, and generic headers are all changed.
|
||||
|
||||
Tested on Linux on armv7hl, i686, x86_64, aarch64, ppc64le, and s390x.

elf: Call __libc_early_init for reused namespaces (bug 29528)
|
||||
|
||||
libc_map is never reset to NULL, neither during dlclose nor on a
|
||||
dlopen call which reuses the namespace structure. As a result, if a
|
||||
namespace is reused, its libc is not initialized properly. The most
|
||||
visible result is a crash in the <ctype.h> functions.
|
||||
|
||||
To prevent similar bugs on namespace reuse from surfacing,
|
||||
unconditionally initialize the chosen namespace to zero using memset.

Apply asm redirections in stdio.h before first use [BZ #27087]
|
||||
|
||||
Compilers may not be able to apply asm redirections to functions after
|
||||
these functions are used for the first time, e.g. clang 13.
|
||||
Fix [BZ #27087] by applying all long double-related asm redirections
|
||||
before using functions in bits/stdio.h.
|
||||
However, as these asm redirections depend on the declarations provided
|
||||
by libio/bits/stdio2.h, this header was split in 2:
|
||||
|
||||
- libio/bits/stdio2-decl.h contains all function declarations;
|
||||
- libio/bits/stdio2.h remains with the remaining contents, including
|
||||
redirections.
|
||||
|
||||
This also adds the access attribute to __vsnprintf_chk that was missing.

commit b41c535f46e7e7bbd8ff2ac68b94c2348e2f66e4

Author: Raphael Moreira Zinsly <rzinsly@linux.ibm.com>

Date: Wed Aug 24 11:43:37 2022 -0300
|
||||
|
||||
Apply asm redirections in wchar.h before first use
|
||||
|
||||
Similar to d0fa09a770, but for wchar.h. Fixes [BZ #27087] by applying
|
||||
all long double related asm redirections before using functions in
|
||||
bits/wchar2.h.
|
||||
Moves the function declarations from wcsmbs/bits/wchar2.h to a new file
|
||||
wcsmbs/bits/wchar2-decl.h that will be included first in wcsmbs/wchar.h.
|
||||
|
||||
Tested with build-many-glibcs.py.

nscd: Fix netlink cache invalidation if epoll is used [BZ #29415]
|
||||
|
||||
Processes cache network interface information such as whether IPv4 or IPv6
|
||||
are enabled. This is only checked again if the "netlink timestamp" provided
|
||||
by nscd changed, which is triggered by netlink socket activity.
|
||||
|
||||
However, in the epoll handler for the netlink socket, it was missed to
|
||||
assign the new timestamp to the nscd database. The handler for plain poll
|
||||
did that properly, copy that over.
|
||||
|
||||
This bug caused that e.g. processes which started before network
|
||||
configuration got unusuable addresses from getaddrinfo, like IPv6 only even
|
||||
though only IPv4 is available:

It's a bit hard to reproduce, so I verified this by checking the timestamp
|
||||
on calls to __check_pf manually. Without this patch it's stuck at 1, now
|
||||
it's increasing on network changes as expected.

elf: Fix hwcaps string size overestimation
|
||||
|
||||
Commit dad90d528259b669342757c37dedefa8577e2636 added glibc-hwcaps
|
||||
support for LD_LIBRARY_PATH and, for this, it adjusted the total
|
||||
string size required in _dl_important_hwcaps. However, in doing so
|
||||
it inadvertently altered the calculation of the size required for
|
||||
the power set strings, as the computation of the power set string
|
||||
size depended on the first value assigned to the total variable,
|
||||
which is later shifted, resulting in overallocation of string
|
||||
space. Fix this now by using a different variable to hold the
|
||||
string size required for glibc-hwcaps.

gconv: Use 64-bit interfaces in gconv_parseconfdir (bug 29583)
|
||||
|
||||
It's possible that inode numbers are outside the 32-bit range.
|
||||
The existing code only handles the in-libc case correctly, and
|
||||
still uses the legacy interfaces when building iconv.

resolv: Add internal __res_binary_hnok function
|
||||
|
||||
During package parsing, only the binary representation is available,
|
||||
and it is convenient to check that directly for conformance with host
|
||||
name requirements.

commit e7c03f47651bd451ebf2c3c65899491d0bf7167e

resolv: Add DNS packet parsing helpers geared towards wire format
|
||||
|
||||
The public parser functions around the ns_rr record type produce
|
||||
textual domain names, but usually, this is not what we need while
|
||||
parsing DNS packets within glibc. This commit adds two new helper
|
||||
functions, __ns_rr_cursor_init and __ns_rr_cursor_next, for writing
|
||||
packet parsers, and struct ns_rr_cursor, struct ns_rr_wire as
|
||||
supporting types.
|
||||
|
||||
In theory, it is possible to avoid copying the owner name
|
||||
into the rname field in __ns_rr_cursor_next, but this would need
|
||||
more functions that work on compressed names.
|
||||
|
||||
Eventually, __res_context_send could be enhanced to preserve the
|
||||
result of the packet parsing that is necessary for matching the
|
||||
incoming UDP packets, so that this works does not have to be done
|
||||
twice.

commit d9c979abf9307ef3e27dbe65317430977bb322c7

Author: Florian Weimer <fweimer@redhat.com>
|

|

|
||||
nss_dns: Split getanswer_ptr from getanswer_r
|
||||
|
||||
And expand the use of name_ok and qtype in getanswer_ptr (the
|
||||
former also in getanswer_r).
|
||||
|
||||
After further cleanups, not much code will be shared between the
|
||||
two functions.

commit 32e5db37684ffcbc6ae34fcc6cdcf28670506baa
|
||||
Author: Florian Weimer <fweimer@redhat.com>
|
||||
Date: Tue Aug 30 10:02:49 2022 +0200
|
||||
|
||||
nss_dns: Rewrite _nss_dns_gethostbyaddr2_r and getanswer_ptr
|
||||
|
||||
The simplification takes advantage of the split from getanswer_r.
|
||||
It fixes various aliases issues, and optimizes NSS buffer usage.
|
||||
The new DNS packet parsing helpers are used, too.

nss_dns: Rewrite getanswer_r to match getanswer_ptr (bug 12154, bug 29305)
|
||||
|
||||
Allocate the pointer arrays only at the end, when their sizes
|
||||
are known. This addresses bug 29305.
|
||||
|
||||
Skip over invalid names instead of failing lookups. This partially
|
||||
fixes bug 12154 (for gethostbyname, fixing getaddrinfo requires
|
||||
different changes).

nss_dns: In gaih_getanswer_slice, skip strange aliases (bug 12154)
|
||||
|
||||
If the name is not a host name, skip adding it to the result, instead
|
||||
of reporting query failure. This fixes bug 12154 for getaddrinfo.
|
||||
|
||||
This commit still keeps the old parsing code, and only adjusts when
|
||||
a host name is copied.

Add LLL_MUTEX_READ_LOCK [BZ #28537]
|
||||
|
||||
CAS instruction is expensive. From the x86 CPU's point of view, getting
|
||||
a cache line for writing is more expensive than reading. See Appendix
|
||||
A.2 Spinlock in:
|
||||
|
||||
https://www.intel.com/content/dam/www/public/us/en/documents/white-papers/xeon-lock-scaling-analysis-paper.pdf
|
||||
|
||||
The full compare and swap will grab the cache line exclusive and cause
|
||||
excessive cache line bouncing.
|
||||
|
||||
Add LLL_MUTEX_READ_LOCK to do an atomic load and skip CAS in spinlock
|
||||
loop if compare may fail to reduce cache line bouncing on contended locks.

nptl: Effectively skip CAS in spinlock loop
|
||||
|
||||
The commit:
|
||||
"Add LLL_MUTEX_READ_LOCK [BZ #28537]"
|
||||
SHA1: d672a98a1af106bd68deb15576710cd61363f7a6
|
||||
|
||||
introduced LLL_MUTEX_READ_LOCK, to skip CAS in spinlock loop
|
||||
if atomic load fails. But, "continue" inside of do-while loop
|
||||
does not skip the evaluation of escape expression, thus CAS
|
||||
is not skipped.
|
||||
|
||||
Replace do-while with while and skip LLL_MUTEX_TRYLOCK if
|
||||
LLL_MUTEX_READ_LOCK fails.

sysdeps: Add 'get_fast_jitter' interace in fast-jitter.h
|
||||
|
||||
'get_fast_jitter' is meant to be used purely for performance
|
||||
purposes. In all cases it's used it should be acceptable to get no
|
||||
randomness (see default case). An example use case is in setting
|
||||
jitter for retries between threads at a lock. There is a
|
||||
performance benefit to having jitter, but only if the jitter can
|
||||
be generated very quickly and ultimately there is no serious issue
|
||||
if no jitter is generated.
|
||||
|
||||
The implementation generally uses 'HP_TIMING_NOW' iff it is
|
||||
inlined (avoid any potential syscall paths).

nptl: Add backoff mechanism to spinlock loop
|
||||
|
||||
When mutiple threads waiting for lock at the same time, once lock owner
|
||||
releases the lock, waiters will see lock available and all try to lock,
|
||||
which may cause an expensive CAS storm.
|
||||
|
||||
Binary exponential backoff with random jitter is introduced. As try-lock
|
||||
attempt increases, there is more likely that a larger number threads
|
||||
compete for adaptive mutex lock, so increase wait time in exponential.
|
||||
A random jitter is also added to avoid synchronous try-lock from other
|
||||
threads.
|
||||
|
||||
v2: Remove read-check before try-lock for performance.
|
||||
|
||||
v3:
|
||||
1. Restore read-check since it works well in some platform.
|
||||
2. Make backoff arch dependent, and enable it for x86_64.
|
||||
3. Limit max backoff to reduce latency in large critical section.
|
||||
|
||||
v4: Fix strict-prototypes error in sysdeps/nptl/pthread_mutex_backoff.h
|
||||
|
||||
v5: Commit log updated for regression in large critical section.

There is regression in large critical section. But adaptive mutex is
|
||||
aimed for "quick" locks. Small critical section is more common when
|
||||
users choose to use adaptive pthread_mutex.

x86-64: Require BMI2 for AVX2 str(n)casecmp implementations
|
||||
|
||||
The AVX2 str(n)casecmp implementations use the 'bzhi' instruction, which
|
||||
belongs to the BMI2 CPU feature.
|
||||
|
||||
NB: It also uses the 'tzcnt' BMI1 instruction, but it is executed as BSF
|
||||
as BSF if the CPU doesn't support TZCNT, and produces the same result
|
||||
for non-zero input.

||||
|
||||
The AVX2 strcmp implementation uses the 'bzhi' instruction, which

belongs to the BMI2 CPU feature.
|
||||
|
||||
NB: It also uses the 'tzcnt' BMI1 instruction, but it is executed as BSF
|

as BSF if the CPU doesn't support TZCNT, and produces the same result
|
||||
for non-zero input.

x86-64: Require BMI2 and LZCNT for AVX2 memrchr implementation
|
||||
|
||||
The AVX2 memrchr implementation uses the 'shlxl' instruction, which
|
||||
belongs to the BMI2 CPU feature and uses the 'lzcnt' instruction, which
|
||||
belongs to the LZCNT CPU feature.
|
||||
|
||||
Fixes: af5306a735eb ("x86: Optimize memrchr-avx2.S")

nscd: Drop local address tuple variable [BZ #29607]
|
||||
|
||||
When a request needs to be resent (e.g. due to insufficient buffer
|
||||
space), the references to subsequent tuples in the local variable are
|
||||
stale and should not be used. This used to work by accident before, but
|
||||
since 1d495912a it no longer does. Instead of trying to reset it, just
|
||||
let gethostbyname4_r write into TUMPBUF6 for us, thus maintaining a
|
||||
consistent state at all times. This is now consistent with what is done
|
||||
in gaih_inet for getaddrinfo.

linux: Fix generic struct_stat for 64 bit time (BZ# 29657)
|
||||
|
||||
The generic Linux struct_stat misses the conditionals to use
|
||||
bits/struct_stat_time64_helper.h in the __USE_TIME_BITS64 for
|
||||
architecture that uses __TIMESIZE == 32 (currently csky and nios2).
|
||||
|
||||
Since newer ports should not support 32 bit time_t, the generic
|
||||
implementation should be used as default.
|
||||
|
||||
For arm, hppa, and sh a copy of default struct_stat is added,
|
||||
while for csky and nios a new one based on generic is used, along
|
||||
with conditionals to use bits/struct_stat_time64_helper.h.
|
||||
|
||||
The default struct_stat is also replaced with the generic one.
|
||||
|
||||
Checked on aarch64-linux-gnu and arm-linux-gnueabihf.
|
||||
|
||||
(cherry picked from commit 7a6ca82f8007ddbd43e2b8fce806ba7101ee47f5)

Makerules: fix MAKEFLAGS assignment for upcoming make-4.4 [BZ# 29564]
|
||||
|
||||
make-4.4 will add long flags to MAKEFLAGS variable:
|
||||
|
||||
* WARNING: Backward-incompatibility!
|
||||
Previously only simple (one-letter) options were added to the MAKEFLAGS
|
||||
variable that was visible while parsing makefiles. Now, all options
|
||||
are available in MAKEFLAGS.
|
||||
|
||||
This causes locale builds to fail when long options are used:
|
||||
|
||||
$ make --shuffle
|
||||
...
|
||||
make -C localedata install-locales
|
||||
make: invalid shuffle mode: '1662724426r'
|
||||
|
||||
The change fixes it by passing eash option via whitespace and dashes.
|
||||
That way option is appended to both single-word form and whitespace
|
||||
separated form.
|
||||
|
||||
While at it fixed --silent mode detection in $(MAKEFLAGS) by filtering
|
||||
out --long-options. Otherwise options like --shuffle flag enable silent
|
||||
mode unintentionally. $(silent-make) variable consolidates the checks.
|
||||

||||

mktime: improve heuristic for ca-1986 Indiana DST
|
||||
|
||||
This patch syncs mktime.c from Gnulib, fixing a
|
||||
problem reported by Mark Krenz <https://bugs.gnu.org/48085>,
|
||||
and it should fix BZ#29035 too.
|
||||
* time/mktime.c (__mktime_internal): Be more generous about
|
||||
accepting arguments with the wrong value of tm_isdst, by falling
|
||||
back to a one-hour DST difference if we find no nearby DST that is
|
||||
unusual. This fixes a problem where "1986-04-28 00:00 EDT" was
|
||||
rejected when TZ="America/Indianapolis" because the nearest DST
|
||||
timestamp occurred in 1970, a temporal distance too great for the
|
||||
old heuristic. This also also narrows the search a bit, which
|
||||
is a minor performance win.

Fix memmove call in vfprintf-internal.c:group_number
|
||||
|
||||
A recent GCC mainline change introduces errors of the form:
|
||||
|
||||
vfprintf-internal.c: In function 'group_number':
|
||||
vfprintf-internal.c:2093:15: error: 'memmove' specified bound between 9223372036854775808 and 18446744073709551615 exceeds maximum object size 9223372036854775807 [-Werror=stringop-overflow=]
|
||||
2093 | memmove (w, s, (front_ptr -s) * sizeof (CHAR_T));
|
||||
| ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
|
||||
|
||||
This is a genuine bug in the glibc code: s > front_ptr is always true
|
||||
at this point in the code, and the intent is clearly for the
|
||||
subtraction to be the other way round. The other arguments to the
|
||||
memmove call here also appear to be wrong; w and s point just *after*
|
||||
the destination and source for copying the rest of the number, so the
|
||||
size needs to be subtracted to get appropriate pointers for the
|
||||
copying. Adjust the memmove call to conform to the apparent intent of
|
||||
the code, so fixing the -Wstringop-overflow error.
|
||||
|
||||
Now, if the original code were ever executed, a buffer overrun would
|
||||
result. However, I believe this code (introduced in commit
|
||||
edc1686af0c0fc2eb535f1d38cdf63c1a5a03675, "vfprintf: Reuse work_buffer
|
||||
in group_number", so in glibc 2.26) is unreachable in prior glibc
|
||||
releases (so there is no need for a bug in Bugzilla, no need to
|
||||
consider any backports unless someone wants to build older glibc
|
||||
releases with GCC 12 and no possibility of this buffer overrun
|
||||
resulting in a security issue).
|
||||
|
||||
work_buffer is 1000 bytes / 250 wide characters. This case is only
|
||||
reachable if an initial part of the number, plus a grouped copy of the
|
||||
rest of the number, fail to fit in that space; that is, if the grouped
|
||||
number fails to fit in the space. In the wide character case,
|
||||
grouping is always one wide character, so even with a locale (of which
|
||||
there aren't any in glibc) grouping every digit, a number would need
|
||||
to occupy at least 125 wide characters to overflow, and a 64-bit
|
||||
integer occupies at most 23 characters in octal including a leading 0.
|
||||
In the narrow character case, the multibyte encoding of the grouping
|
||||
separator would need to be at least 42 bytes to overflow, again
|
||||
supposing grouping every digit, but MB_LEN_MAX is 16. So even if we
|
||||
admit the case of artificially constructed locales not shipped with
|
||||
glibc, given that such a locale would need to use one of the character
|
||||
sets supported by glibc, this code cannot be reached at present. (And
|
||||
POSIX only actually specifies the ' flag for grouping for decimal
|
||||
output, though glibc acts on it for other bases as well.)
|
||||
|
||||
With binary output (if you consider use of grouping there to be
|
||||
valid), you'd need a 15-byte multibyte character for overflow; I don't
|
||||
know if any supported character set has such a character (if, again,
|
||||
we admit constructed locales using grouping every digit and a grouping
|
||||
separator chosen to have a multibyte encoding as long as possible, as
|
||||
well as accepting use of grouping with binary), but given that we have
|
||||
this code at all (clearly it's not *correct*, or in accordance with
|
||||
the principle of avoiding arbitrary limits, to skip grouping on
|
||||
running out of internal space like that), I don't think it should need
|
||||
any further changes for binary printf support to go in.
|
||||
|
||||
On the other hand, support for large sizes of _BitInt in printf (see
|
||||
the N2858 proposal) *would* require something to be done about such
|
||||
arbitrary limits (presumably using dynamic allocation in printf again,
|
||||
for sufficiently large _BitInt arguments only - currently only
|
||||
floating-point uses dynamic allocation, and, as previously discussed,
|
||||
that could actually be replaced by bounded allocation given smarter
|
||||
code).
|
||||
|
||||
Tested with build-many-glibcs.py for aarch64-linux-gnu (GCC mainline).
|
||||
Also tested natively for x86_64.

Allow #pragma GCC in headers in conformtest
|
||||
|

No "#pragma GCC" pragma allows macro-expansion of its arguments, so no

namespace issues arise from use of such pragmas in installed headers.

Ignore them in conformtest tests of header namespace.

regex: copy back from Gnulib
|
||||
|
||||
Copy regex-related files back from Gnulib, to fix a problem with
|
||||
static checking of regex calls noted by Martin Sebor. This merges the
|
||||
following changes:
|
||||
|
||||
* New macro __attribute_nonnull__ in misc/sys/cdefs.h, for use later
|
||||
when copying other files back from Gnulib.
|
||||
|
||||
* Use __GNULIB_CDEFS instead of __GLIBC__ when deciding
|
||||
whether to include bits/wordsize.h etc.
|
||||
|
||||
* Avoid duplicate entries in epsilon closure table.
|
||||
|
||||
* New regex.h macro _REGEX_NELTS to let regexec say that its pmatch
|
||||
arg should contain nmatch elts. Use that for regexec, instead of
|
||||
__attr_access (which is incorrect).
|
||||
|
||||
* New regex.h macro _Attr_access_ which is like __attr_access except
|
||||
portable to non-glibc platforms.
|
||||
|
||||
* Add some DEBUG_ASSERTs to pacify gcc -fanalyzer and to catch
|
||||
recently-fixed performance bugs if they recur.
|
||||
|
||||
* Add Gnulib-specific stuff to port the dynarray- and lock-using parts
|
||||
of regex code to non-glibc platforms.
|
||||
|
||||
* Fix glibc bug 11053.
|
||||
|
||||
* Avoid some undefined behavior when popping an empty fail stack.

io: Fix ftw internal realloc buffer (BZ #28126)
|
||||
|
||||
The 106ff08526d3ca did not take in consideration the buffer might be
|
||||
reallocated if the total path is larger than PATH_MAX. The realloc
|
||||
uses 'dirbuf', where 'dirstreams' is the allocated buffer.
|
||||
|
||||
Checked on x86_64-linux-gnu.

elf: Fix rtld-audit trampoline for aarch64
|
||||
|
||||
This patch fixes two problems with audit:
|
||||
|
||||
1. The DL_OFFSET_RV_VPCS offset was mixed up with DL_OFFSET_RG_VPCS,
|
||||
resulting in x2 register value nulling in RG structure.
|
||||
|
||||
2. We need to preserve the x8 register before function call, but
|
||||
don't have to save it's new value and restore it before return.
|
||||
|
||||
Anyway the final restore was using OFFSET_RV instead of OFFSET_RG value
|
||||
which is wrong (althoug doesn't affect anything).

x86: Fix wcsnlen-avx2 page cross length comparison [BZ #29591]
|
||||
|
||||
Previous implementation was adjusting length (rsi) to match
|
||||
bytes (eax), but since there is no bound to length this can cause
|
||||
overflow.
|
||||
|
||||
Fix is to just convert the byte-count (eax) to length by dividing by
|
||||
sizeof (wchar_t) before the comparison.
|
||||
|
||||
Full check passes on x86-64 and build succeeds w/ and w/o multiarch.

commit 42b9d7def8fd7d26f1926cbc801923aa2c8a386a
|
||||
Author: DJ Delorie <dj@redhat.com>
|
||||

|
||||
|
||||
Allow for unpriviledged nested containers
|
||||
|
||||
If the build itself is run in a container, we may not be able to
|
||||
fully set up a nested container for test-container testing.
|
||||
Notably is the mounting of /proc, since it's critical that it
|
||||
be mounted from within the same PID namespace as its users, and
|
||||
thus cannot be bind mounted from outside the container like other
|
||||
mounts.
|
||||
|
||||
This patch defaults to using the parent's PID namespace instead of
|
||||
creating a new one, as this is more likely to be allowed.
|
||||
|
||||
If the test needs an isolated PID namespace, it should add the "pidns"
|
||||
command to its init script.

elf: Fix wrong fscanf usage on tst-pldd
|
||||
|
||||
The fix done b2cd93fce666fdc8c9a5c64af2741a8a6940ac99 does not really
|
||||
work since macro strification does not expand the sizeof nor the
|
||||
arithmetic operation.
|
||||
|
||||
Checked on x86_64-linux-gnu.

_Static_assert needs two arguments for compatibility with GCC before 9
|

|

This macro definition enforces two arguments even with newer compilers

that accept the single-argument form, too.

Similar to d0fa09a770, but for syslog.h when _FORTIFY_SOURCE > 0.

Also, to avoid adding both LFS and 64 bit time support on internal

tests they are moved to a newer 'testsuite-internal' module. It

should be similar to 'nonlib' regarding internal definition and

This patch also enables LFS and 64 bit support of libsupport container

elf: Drop elf/tls-macros.h in favor of __thread and tls_model attributes [BZ #28152] [BZ #28205]
|
||||
|
||||
elf/tls-macros.h was added for TLS testing when GCC did not support
|
||||
__thread. __thread and tls_model attributes are mature now and have been
|
||||
used by many newer tests.
|
||||
|
||||
Also delete tst-tls2.c which tests .tls_common (unused by modern GCC and
|
||||
unsupported by Clang/LLD). .tls_common and .tbss definition are almost
|
||||
identical after linking, so the runtime test doesn't add additional
|
||||
coverage. Assembler and linker tests should be on the binutils side.
|
||||
|
||||
When LLD 13.0.0 is allowed in configure.ac
|
||||
(https://sourceware.org/pipermail/libc-alpha/2021-August/129866.html),
|
||||
`make check` result is on par with glibc built with GNU ld on aarch64
|
||||
and x86_64.
|
||||
|
||||
As a future clean-up, TLS_GD/TLS_LD/TLS_IE/TLS_IE macros can be removed from
|
||||
sysdeps/*/tls-macros.h. We can add optional -mtls-dialect={gnu2,trad}
|
||||
tests to ensure coverage.
|
||||
|
||||
Tested on aarch64-linux-gnu, powerpc64le-linux-gnu, and x86_64-linux-gnu.

resolv: Avoid GCC 12 false positive warning [BZ #28439].

to avoid a GCC 12 -Wformat-overflow false positive due to recent optimizer
|

improvements.

Fix stdlib/tst-setcontext.c for GCC 12 -Warray-compare
|
||||
|

Building stdlib/tst-setcontext.c fails with GCC mainline:
|
||||
|
||||
tst-setcontext.c: In function 'f2':
|
||||
tst-setcontext.c:61:16: error: comparison between two arrays [-Werror=array-compare]

61 | if (on_stack < st2 || on_stack >= st2 + sizeof (st2))
|
||||
| ^
|
||||
tst-setcontext.c:61:16: note: use '&on_stack[0] < &st2[0]' to compare the addresses
|
||||
|
||||
The comparison in this case is deliberate, so adjust it as suggested
|
||||
in that note.
|
||||
|
||||
Tested with build-many-glibcs.py (GCC mainline) for aarch64-linux-gnu.

Fix stdio-common tests for GCC 12 -Waddress
|
||||
|
||||
My glibc bot shows failures building the testsuite with GCC mainline
|
||||
across all architectures:
|
||||
|
||||
tst-vfprintf-width-prec.c: In function 'do_test':
|
||||
tst-vfprintf-width-prec.c:90:16: error: the comparison will always evaluate as 'false' for the address of 'result' will never be NULL [-Werror=address]
|
||||
90 | if (result == NULL)
|
||||
| ^~
|
||||
tst-vfprintf-width-prec.c:89:13: note: 'result' declared here
|
||||
89 | wchar_t result[100];
|
||||
| ^~~~~~
|
||||
|
||||
This is clearly a correct warning; the comparison against NULL is
|
||||
clearly a cut-and-paste mistake from an earlier case in the test that
|
||||
does use calloc. Thus, remove the unnecessary check for NULL shown up
|
||||
by the warning.
|
||||
|
||||
Similarly, two other tests have bogus comparisons against NULL; remove
|
||||
those as well:
|
||||
|
||||
scanf14a.c:95:13: error: the comparison will always evaluate as 'false' for the address of 'fname' will never be NULL [-Werror=address]
|
||||

|
||||

||||

Fix build of nptl/tst-thread_local1.cc with GCC 12
|
||||
|
||||
The test nptl/tst-thread_local1.cc fails to build with GCC mainline
|

because of changes to what libstdc++ headers implicitly include what
|
||||
other headers:
|
||||
|

tst-thread_local1.cc: In function 'int do_test()':
|
||||
tst-thread_local1.cc:177:5: error: variable 'std::array<std::pair<const char*, std::function<void(void* (*)(void*))> >, 2> do_thread_X' has initializer but incomplete type
|

malloc: Fix -Wuse-after-free warning in tst-mallocalign1 [BZ #26779]
|
||||
|
||||
The test leaks bits from the freed pointer via the return value
|
||||
in ret, and the compiler correctly identifies this issue.
|
||||
We switch the test to use TEST_VERIFY and terminate the test
|
||||
if any of the pointers return an unexpected alignment.
|
||||
|
||||
This fixes another -Wuse-after-free error when compiling glibc
|
||||
with gcc 12.
|
||||
|
||||
Tested on x86_64 and i686 without regression.

cdefs: Limit definition of fortification macros
|
||||
|
||||
Define the __glibc_fortify and other macros only when __FORTIFY_LEVEL >
|
||||
0. This has the effect of not defining these macros on older C90
|
||||
compilers that do not have support for variable length argument lists.
|
||||
|
||||
Also trim off the trailing backslashes from the definition of
|
||||
__glibc_fortify and __glibc_fortify_n macros.

elf: Fix 64 time_t support for installed statically binaries
|
||||
|
||||
The usage of internal static symbol for statically linked binaries
|
||||
does not work correctly for objects built with -D_TIME_BITS=64,
|
||||
since the internal definition does not provide the expected aliases.
|
||||
|
||||
This patch makes it to use the default stat functions instead (which
|
||||
uses the default 64 time_t alias and types).
|
||||
|
||||
Checked on i686-linux-gnu.
