resolv: Support clearing option flags with a “-” prefix (bug 14799)
I think using a “-” prefix is less confusing than introducing
double-negation construct (“no-no-tld-query”).

Subject: powerpc64: Replace some PPC_FEATURE_HAS_VSX with
PPC_FEATURE_ARCH_2_06
We use PPC_FEATURE_HAS_VSX to select a number of POWER7 optimised
functions. These functions don't use any VSX instructions, so
PPC_FEATURE_ARCH_2_06 seems like a better fit.

routines
A number of optimised memset routines assume the cacheline size is 128B,
so we better check before using them.

From: Mahesh Bodapati <bmahi496@linux.ibm.com>

Subject: PowerPC: Influence cpu/arch hwcap features via GLIBC_TUNABLES
This patch enables the option to influence hwcaps used by PowerPC.
The environment variable, GLIBC_TUNABLES=glibc.cpu.hwcaps=-xxx,yyy,-zzz....,
can be used to enable CPU/ARCH feature yyy, disable CPU/ARCH feature xxx
and zzz, where the feature name is case-sensitive and has to match the ones
mentioned in the file{sysdeps/powerpc/dl-procinfo.c}.
Note that the hwcap tunables only used in the IFUNC selection.

commit 1493622f4f9048ffede3fbedb64695efa49d662a

Date: Mon Aug 28 12:08:14 2023 -0700
x86: Check the lower byte of EAX of CPUID leaf 2 [BZ #30643]
The old Intel software developer manual specified that the low byte of
EAX of CPUID leaf 2 returned 1 which indicated the number of rounds of
CPUDID leaf 2 was needed to retrieve the complete cache information. The
newer Intel manual has been changed to that it should always return 1
and be ignored. If the lower byte isn't 1, CPUID leaf 2 can't be used.
In this case, we ignore CPUID leaf 2 and use CPUID leaf 4 instead. If
CPUID leaf 4 doesn't contain the cache information, cache information
isn't available at all. This addresses BZ #30643.

ldconfig: Fixes for skipping temporary files.
Arguments to a memchr call were swapped, causing incorrect skipping
of files.
Files related to dpkg have different names: they actually end in
.dpkg-new and .dpkg-tmp, not .tmp as I mistakenly assumed.
Fixes commit 2aa0974d2573441bffd59 ("elf: ldconfig should skip
temporary files created by package managers").

string: Add tests for strndup (BZ #30266)
Copy strncpy tests for strndup. Covers some basic testcases with random
strings. Remove tests that set the destination's bytes and checked the
resulting buffer's bytes. Remove wide character test support since
wcsndup() doesn't exist.

commit 72511f539cc34681ec61c6a0dc2fe6d684760ffe
Author: Joseph Myers <joseph@codesourcery.com>
Date: Tue Sep 12 14:08:53 2023 +0000
Update syscall lists for Linux 6.5
Linux 6.5 has one new syscall, cachestat, and also enables the
cacheflush syscall for hppa. Update syscall-names.list and regenerate
the arch-syscall.h headers with build-many-glibcs.py update-syscalls.
Tested with build-many-glibcs.py.
Conflicts: Removed loongarch, or1k

commit bc0d18d873abf2cda6842ad8bb4df2a31dc0fbac
Author: Siddhesh Poyarekar <siddhesh@sourceware.org>
Date: Tue Aug 3 21:29:23 2021 +0530
gai_init: Avoid jumping from if condition to its else counterpart
Clean up another antipattern where code flows from an if condition to
its else counterpart with a goto.
Most of the change in this patch is whitespace-only; a `git diff -b`
ought to show the actual logic changes.

elf: Fix TLS modid reuse generation assignment (BZ 29039)
_dl_assign_tls_modid() assigns a slotinfo entry for a new module, but
does *not* do anything to the generation counter. The first time this
happens, the generation is zero and map_generation() returns the current
generation to be used during relocation processing. However, if
a slotinfo entry is later reused, it will already have a generation
assigned. If this generation has fallen behind the current global max
generation, then this causes an obsolete generation to be assigned
during relocation processing, as map_generation() returns this
generation if nonzero. _dl_add_to_slotinfo() eventually resets the
generation, but by then it is too late. This causes DTV updates to be
skipped, leading to NULL or broken TLS slot pointers and segfaults.
Fix this by resetting the generation to zero in _dl_assign_tls_modid(),
so it behaves the same as the first time a slot is assigned.
_dl_add_to_slotinfo() will still assign the correct static generation
later during module load, but relocation processing will no longer use
an obsolete generation.
Note that slotinfo entry (aka modid) reuse typically happens after a
dlclose and only TLS access via dynamic tlsdesc is affected. Because
tlsdesc is optimized to use the optional part of static TLS, dynamic
tlsdesc can be avoided by increasing the glibc.rtld.optional_static_tls
tunable to a large enough value, or by LD_PRELOAD-ing the affected
modules.
Fixes bug 29039.

elf: Add TLS modid reuse test for bug 29039
This is a minimal regression test for bug 29039 which only affects
targets with TLSDESC and a reproducer requires that
1) Have modid gaps (closed modules) with old generation.
2) Update a DTV to a newer generation (needs a newer dlopen).
3) But do not update the closed gap entry in that DTV.
4) Reuse the modid gap for a new module (another dlopen).
5) Use dynamic TLSDESC in that new module with old generation (bug).
6) Access TLS via this TLSDESC and the now outdated DTV.
However step (3) in practice rarely happens: during DTV update the
entries for closed modids are initialized to "unallocated" and then
dynamic TLSDESC calls __tls_get_addr independently of its generation.
The only exception to this is DTV setup at thread creation (gaps are
initialized to NULL instead of unallocated) or DTV resize where the
gap entries are outside the previous DTV array (again NULL instead
of unallocated, and this requires loading > DTV_SURPLUS modules).
So the bug can only cause NULL (+ offset) dereference, not use after
free. And the easiest way to get (3) is via thread creation.
Note that step (5) requires that the newly loaded module has larger
TLS than the remaining optional static TLS. And for (6) there cannot
be other TLS access or dlopen in the thread that updates the DTV.
Tested on aarch64-linux-gnu.

libio: Check remaining buffer size in _IO_wdo_write (bug 31183)
The multibyte character needs to fit into the remaining buffer space,
not the already-written buffer space. Without the fix, we were never
moving the write pointer from the start of the buffer, always using
the single-character fallback buffer.
Fixes commit 04b76b5aa8b2d1d19066e42dd1 ("Don't error out writing
a multibyte character to an unbuffered stream (bug 17522)").

From 317f1c0a8a71a862b1e600ff5386b08e02cf4b95 Mon Sep 17 00:00:00 2001

Subject: [PATCH] x86-64: Add glibc.cpu.prefer_map_32bit_exec [BZ #28656]
Content-type: text/plain; charset=UTF-8
Crossing 2GB boundaries with indirect calls and jumps can use more
branch prediction resources on Intel Golden Cove CPU (see the
"Misprediction for Branches >2GB" section in Intel 64 and IA-32
Architectures Optimization Reference Manual.) There is visible
performance improvement on workloads with many PLT calls when executable
and shared libraries are mmapped below 2GB. Add the Prefer_MAP_32BIT_EXEC
bit so that mmap will try to map executable or denywrite pages in shared
libraries with MAP_32BIT first.
NB: Prefer_MAP_32BIT_EXEC reduces bits available for address space
layout randomization (ASLR), which is always disabled for SUID programs
and can only be enabled by the tunable, glibc.cpu.prefer_map_32bit_exec,
or the environment variable, LD_PREFER_MAP_32BIT_EXEC. This works only
between shared libraries or between shared libraries and executables with
addresses below 2GB. PIEs are usually loaded at a random address above
4GB by the kernel.

elf: Fix slow tls access after dlopen [BZ #19924]
In short: __tls_get_addr checks the global generation counter and if
the current dtv is older then _dl_update_slotinfo updates dtv up to the
generation of the accessed module. So if the global generation is newer
than generation of the module then __tls_get_addr keeps hitting the
slow dtv update path. The dtv update path includes a number of checks
to see if any update is needed and this already causes measurable tls
access slow down after dlopen.
It may be possible to detect up-to-date dtv faster. But if there are
many modules loaded (> TLS_SLOTINFO_SURPLUS) then this requires at
least walking the slotinfo list.
This patch tries to update the dtv to the global generation instead, so
after a dlopen the tls access slow path is only hit once. The modules
with larger generation than the accessed one were not necessarily
synchronized before, so additional synchronization is needed.
This patch uses acquire/release synchronization when accessing the
generation counter.
Note: in the x86_64 version of dl-tls.c the generation is only loaded
once, since relaxed mo is not faster than acquire mo load.
I have not benchmarked this. Tested by Adhemerval Zanella on aarch64,
powerpc, sparc, x86 who reported that it fixes the performance issue
of bug 19924.

+
+ Here we update the thread dtv from old_gen (== dtv[0].counter) to

malloc: Do not use MAP_NORESERVE to allocate heap segments
Address space for heap segments is reserved in a mmap call with
MAP_ANONYMOUS | MAP_PRIVATE and protection flags PROT_NONE. This
reservation does not count against the RSS limit of the process or
system. Backing memory is allocated using mprotect in alloc_new_heap
and grow_heap, and at this point, the allocator expects the kernel
to provide memory (subject to memory overcommit).
The SIGSEGV that might generate due to MAP_NORESERVE (according to
the mmap manual page) does not seem to occur in practice, it's always
SIGKILL from the OOM killer. Even if there is a way that SIGSEGV
could be generated, it is confusing to applications that this only
happens for secondary heaps, not for large mmap-based allocations,
and not for the main arena.

+@cindex program interpreter
+When a dynamically linked program starts, the operating system
+automatically loads the dynamic linker along with the program.
+@Theglibc{} also supports invoking the dynamic linker explicitly to
+launch a program. This command uses the implied dynamic linker
+(also sometimes called the @dfn{program interpreter}):
+
+@smallexample
+sh -c 'echo "Hello, world!"'
+@end smallexample
+
+This command specifies the dynamic linker explicitly:
+
+@smallexample
+ld.so /bin/sh -c 'echo "Hello, world!"'
+@end smallexample
+
+Note that @command{ld.so} does not search the @env{PATH} environment
+variable, so the full file name of the executable needs to be specified.
+
+The @command{ld.so} program supports various options. Options start
+@samp{--} and need to come before the program that is being launched.
+Some of the supported options are listed below.

+@cindex diagnostics (dynamic linker)
+
+The @samp{ld.so --list-diagnostics} produces machine-readable
+diagnostics output. This output contains system data that affects the
+behavior of @theglibc{}, and potentially application behavior as well.
+
+The exact set of diagnostic items can change between releases of
+@theglibc{}. The output format itself is not expected to change
+radically.
+
+The following table shows some example lines that can be written by the
+diagnostics command.
+
+@table @code
+@item dl_pagesize=0x1000
+The system page size is 4096 bytes.
+
+@item env[0x14]="LANG=en_US.UTF-8"
+This item indicates that the 21st environment variable at process
+startup contains a setting for @code{LANG}.
+
+@item env_filtered[0x22]="DISPLAY"
+The 35th environment variable is @code{DISPLAY}. Its value is not
+included in the output for privacy reasons because it is not recognized
+as harmless by the diagnostics code.
+
+@item path.prefix="/usr"
+This means that @theglibc{} was configured with @code{--prefix=/usr}.
+
+@item path.system_dirs[0x0]="/lib64/"
+@itemx path.system_dirs[0x1]="/usr/lib64/"
+The built-in dynamic linker search path contains two directories,
+@code{/lib64} and @code{/usr/lib64}.
+@end table
+
+@subsection Dynamic Linker Diagnostics Output Format
+
+As seen above, diagnostic lines assign values (integers or strings) to a
+sequence of labeled subscripts, separated by @samp{.}. Some subscripts
+have integer indices associated with them. The subscript indices are
+not necessarily contiguous or small, so an associative array should be
+used to store them. Currently, all integers fit into the 64-bit
+unsigned integer range. Every access path to a value has a fixed type
+(string or integer) independent of subscript index values. Likewise,
+whether a subscript is indexed does not depend on previous indices (but
+may depend on previous subscript labels).
+
+A syntax description in ABNF (RFC 5234) follows. Note that
+@code{%x30-39} denotes the range of decimal digits. Diagnostic output
+lines are expected to match the @code{line} production.
+
+@c ABNF-START
+@smallexample
+HEXDIG = %x30-39 / %x61-6f ; lowercase a-f only
+ALPHA = %x41-5a / %x61-7a / %x7f ; letters and underscore
+ALPHA-NUMERIC = ALPHA / %x30-39 / "_"
+DQUOTE = %x22 ; "
+
+; Numbers are always hexadecimal and use a 0x prefix.
+hex-value-prefix = %x30 %x78
+hex-value = hex-value-prefix 1*HEXDIG
+
+; Strings use octal escape sequences and \\, \".
+string-char = %x20-21 / %x23-5c / %x5d-7e ; printable but not "\
+string-quoted-octal = %x30-33 2*2%x30-37
+string-quoted = "\" ("\" / DQUOTE / string-quoted-octal)
+string-value = DQUOTE *(string-char / string-quoted) DQUOTE
+
+value = hex-value / string-value
+
+label = ALPHA *ALPHA-NUMERIC
+index = "[" hex-value "]"
+subscript = label [index]
+
+line = subscript *("." subscript) "=" value
+@end smallexample
+
+@subsection Dynamic Linker Diagnostics Values
+
+As mentioned above, the set of diagnostics may change between
+@theglibc{} releases. Nevertheless, the following table documents a few
+common diagnostic items. All numbers are in hexadecimal, with a
+@samp{0x} prefix.
+
+@table @code
+@item dl_dst_lib=@var{string}
+The @code{$LIB} dynamic string token expands to @var{string}.
+
+@cindex HWCAP (diagnostics)
+@item dl_hwcap=@var{integer}
+@itemx dl_hwcap2=@var{integer}
+The HWCAP and HWCAP2 values, as returned for @code{getauxval}, and as
+used in other places depending on the architecture.
+
+@cindex page size (diagnostics)
+@item dl_pagesize=@var{integer}
+The system page size is @var{integer} bytes.
+
+@item dl_platform=@var{string}
+The @code{$PLATFORM} dynamic string token expands to @var{string}.
+
+@item dso.libc=@var{string}
+This is the soname of the shared @code{libc} object that is part of
+@theglibc{}. On most architectures, this is @code{libc.so.6}.
+
+@item env[@var{index}]=@var{string}
+@itemx env_filtered[@var{index}]=@var{string}
+An environment variable from the process environment. The integer
+@var{index} is the array index in the environment array. Variables
+under @code{env} include the variable value after the @samp{=} (assuming
+that it was present), variables under @code{env_filtered} do not.
+
+@item path.prefix=@var{string}
+This indicates that @theglibc{} was configured using
+@samp{--prefix=@var{string}}.
+
+@item path.sysconfdir=@var{string}
+@Theglibc{} was configured (perhaps implicitly) with
+@samp{--sysconfdir=@var{string}} (typically @code{/etc}).
+
+@item path.system_dirs[@var{index}]=@var{string}
+These items list the elements of the built-in array that describes the
+default library search path. The value @var{string} is a directory file
+name with a trailing @samp{/}.
+
+@item path.rtld=@var{string}
+This string indicates the application binary interface (ABI) file name
+of the run-time dynamic linker.
+
+@item version.release="stable"
+@itemx version.release="development"
+The value @code{"stable"} indicates that this build of @theglibc{} is
+from a release branch. Releases labeled as @code{"development"} are
+unreleased development versions.
+
+@cindex version (diagnostics)
+@item version.version="@var{major}.@var{minor}"
+@itemx version.version="@var{major}.@var{minor}.9000"
+@Theglibc{} version. Development releases end in @samp{.9000}.
+
+@cindex auxiliary vector (diagnostics)
+@item auxv[@var{index}].a_type=@var{type}
+@itemx auxv[@var{index}].a_val=@var{integer}
+@itemx auxv[@var{index}].a_val_string=@var{string}
+An entry in the auxiliary vector (specific to Linux). The values
+@var{type} (an integer) and @var{integer} correspond to the members of
+@code{struct auxv}. If the value is a string, @code{a_val_string} is
+used instead of @code{a_val}, so that values have consistent types.
+
+The @code{AT_HWCAP} and @code{AT_HWCAP2} values in this output do not
+reflect adjustment by @theglibc{}.
+
+@item uname.sysname=@var{string}
+@itemx uname.nodename=@var{string}
+@itemx uname.release=@var{string}
+@itemx uname.version=@var{string}
+@itemx uname.machine=@var{string}
+@itemx uname.domain=@var{string}
+These Linux-specific items show the values of @code{struct utsname}, as
+reported by the @code{uname} function. @xref{Platform Type}.
+
+@cindex CPUID (diagnostics)
+@item x86.cpu_features.@dots{}
+These items are specific to the i386 and x86-64 architectures. They
+reflect supported CPU features and information on cache geometry, mostly
+collected using the @code{CPUID} instruction.

x86: Add generic CPUID data dumper to ld.so --list-diagnostics
This is surprisingly difficult to implement if the goal is to produce
reasonably sized output. With the current approaches to output
compression (suppressing zeros and repeated results between CPUs,
folding ranges of identical subleaves, dealing with the %ecx
reflection issue), the output is less than 600 KiB even for systems
with 256 logical CPUs.

+
+@item x86.processor[@var{index}].ecx_limit=@var{value}
+The CPUID data extraction code uses a brute-force approach to enumerate

+These lines report the register contents after executing the CPUID
+instruction with @samp{%rax == @var{query_eax}} and @samp{%rcx == 0} (a
+@dfn{leaf}). For the first probed CPU (with a zero @var{index}), only
+leaves with non-zero register contents are reported. For subsequent
+CPUs, only leaves whose register contents differs from the previously
+probed CPUs (with @var{index} one less) are reported.
+
+Basic and extended leaves are reported using the same syntax. This
+means there is a large jump in @var{query_eax} for the first reported
+extended leaf.

+@itemx x86.processor[@var{index}].cpuid.subleaf_eax[@var{query_eax}].ecx[@var{query_ecx}].edx=@var{edx}
+This is similar to the leaves above, but for a @dfn{subleaf}. For
+subleaves, the CPUID instruction is executed with @samp{%rax ==
+@var{query_eax}} and @samp{%rcx == @var{query_ecx}}, so the result
+depends on both register values. The same rules about filtering zero
+and identical results apply.
+
+@item x86.processor[@var{index}].cpuid.subleaf_eax[@var{query_eax}].ecx[@var{query_ecx}].until_ecx=@var{ecx_limit}
+Some CPUID results are the same regardless the @var{query_ecx} value.
+If this situation is detected, a line with the @samp{.until_ecx}

+
+@item x86.processor[@var{index}].cpuid.subleaf_eax[@var{query_eax}].ecx[@var{query_ecx}].ecx_query_mask=0xff
+This line indicates that in an @samp{.until_ecx} range, the CPUID
+instruction preserved the lowested 8 bits of the input @code{%rcx} in
+the output @code{%rcx} registers. Otherwise, the subleaves in the range
+have identical values. This special treatment is necessary to report
+compact range information in case such copying occurs (because the
+subleaves would otherwise be all different).
+
+@item x86.processor[@var{index}].xgetbv.ecx[@var{query_ecx}]=@var{result}
+This line shows the 64-bit @var{result} value in the @code{%rdx:%rax}

commit 5361ad3910c257bc327567be76fde532ed238e42
Author: Florian Weimer <fweimer@redhat.com>
Date: Fri Apr 19 14:38:17 2024 +0200
login: Use unsigned 32-bit types for seconds-since-epoch
These fields store timestamps when the system was running. No Linux
systems existed before 1970, so these values are unused. Switching
to unsigned types allows continued use of the existing struct layouts
beyond the year 2038.
The intent is to give distributions more time to switch to improved
interfaces that also avoid locking/data corruption issues.

linux: use statx for fstat if neither newfstatat nor fstatat64 is present
LoongArch is going to be the first architecture supported by Linux that
has neither fstat* nor newfstatat [1], instead exclusively relying on
statx. So in fstatat64's implementation, we need to also enable statx
usage if neither fstatat64 nor newfstatat is present, to prepare for
this new case of kernel ABI.

io: Do not implement fstat with fstatat
AT_EMPTY_PATH is a requirement to implement fstat over fstatat,
however it does not prevent the kernel to read the path argument.
It is not an issue, but on x86-64 with SMAP-capable CPUs the kernel is
forced to perform expensive user memory access. After that regular
lookup is performed which adds even more overhead.
Instead, issue the fstat syscall directly on LFS fstat implementation
(32 bit architectures will still continue to use statx, which is
required to have 64 bit time_t support). it should be even a
small performance gain on non x86_64, since there is no need
to handle the path argument.
Checked on x86_64-linux-gnu.

commit 6a04404521ac4119ae36827eeb288ea84eee7cf6
Author: Florian Weimer <fweimer@redhat.com>

Linux: Switch back to assembly syscall wrapper for prctl (bug 29770)
Commit ff026950e280bc3e9487b41b460fb31bc5b57721 ("Add a C wrapper for
prctl [BZ #25896]") replaced the assembler wrapper with a C function.
However, on powerpc64le-linux-gnu, the C variadic function
implementation requires extra work in the caller to set up the
parameter save area. Calling a function that needs a parameter save
area without one (because the prototype used indicates the function is
not variadic) corrupts the caller's stack. The Linux manual pages
project documents prctl as a non-variadic function. This has resulted
in various projects over the years using non-variadic prototypes,
including the sanitizer libraries in LLVm and GCC (GCC PR 113728).
This commit switches back to the assembler implementation on most
targets and only keeps the C implementation for x86-64 x32.
Also add the __prctl_time64 alias from commit
b39ffab860cd743a82c91946619f1b8158b0b65e ("Linux: Add time64 alias for
prctl") to sysdeps/unix/sysv/linux/syscalls.list; it was not yet
present in commit ff026950e280bc3e9487b41b460fb31bc5b57721.
This restores the old ABI on powerpc64le-linux-gnu, thus fixing
bug 29770.

gaih_inet: split loopback lookup into its own function
Flatten the condition nesting and replace the alloca for RET.AT/ATR with
a single array LOCAL_AT[2]. This gets rid of alloca and alloca
accounting.
`git diff -b` is probably the best way to view this change since much of
the diff is whitespace changes.

gethosts: Return EAI_MEMORY on allocation failure
All other cases of failures due to lack of memory return EAI_MEMORY, so
it seems wrong to return EAI_SYSTEM here. The only reason
convert_hostent_to_gaih_addrtuple could fail is on calloc failure.

commit e09ee267c03e3150c2c9ba28625ab130705a485e

getaddrinfo: Fix use after free in getcanonname (CVE-2023-4806)
When an NSS plugin only implements the _gethostbyname2_r and
_getcanonname_r callbacks, getaddrinfo could use memory that was freed
during tmpbuf resizing, through h_name in a previous query response.
The backing store for res->at->name when doing a query with
gethostbyname3_r or gethostbyname2_r is tmpbuf, which is reallocated in
gethosts during the query. For AF_INET6 lookup with AI_ALL |
AI_V4MAPPED, gethosts gets called twice, once for a v6 lookup and second
for a v4 lookup. In this case, if the first call reallocates tmpbuf
enough number of times, resulting in a malloc, th->h_name (that
res->at->name refers to) ends up on a heap allocated storage in tmpbuf.
Now if the second call to gethosts also causes the plugin callback to
return NSS_STATUS_TRYAGAIN, tmpbuf will get freed, resulting in a UAF
reference in res->at->name. This then gets dereferenced in the
getcanonname_r plugin call, resulting in the use after free.
Fix this by copying h_name over and freeing it at the end. This
resolves BZ #30843, which is assigned CVE-2023-4806.

Disable DT_RUNPATH on NSS tests [BZ #28455]
The glibc internal NSS functions should always load NSS modules from
the system. For testing purpose, disable DT_RUNPATH on NSS tests so
that the glibc internal NSS functions can load testing NSS modules
via DT_RPATH.
This partially fixes BZ #28455.

getaddrinfo: Fix leak with AI_ALL [BZ #28852]
Use realloc in convert_hostent_to_gaih_addrtuple and fix up pointers in
the result list so that a single block is maintained for
hostbyname3_r/hostbyname2_r and freed in gaih_inet. This result is
never merged with any other results, since the hosts database does not
permit merging.
Resolves BZ #28852.

commit e05e5889b8a307fe4be55b03bcbd7a1c62fc2f2d
Author: Siddhesh Poyarekar <siddhesh@sourceware.org>
Date: Thu Feb 10 13:27:11 2022 +0530
gaih_inet: Simplify service resolution
Refactor the code to split out the service resolution code into a
separate function. Allocate the service tuples array just once to the
size of the typeproto array, thus avoiding the unnecessary pointer
chasing and stack allocations.

commit 1c37b8022e8763fedbb3f79c02e05c6acfe5a215
Author: Siddhesh Poyarekar <siddhesh@sourceware.org>
Date: Thu Mar 17 11:44:34 2022 +0530
Simplify allocations and fix merge and continue actions [BZ #28931]
Allocations for address tuples is currently a bit confusing because of
the pointer chasing through PAT, making it hard to observe the sequence
in which allocations have been made. Narrow scope of the pointer
chasing through PAT so that it is only used where necessary.
This also tightens actions behaviour with the hosts database in
getaddrinfo to comply with the manual text. The "continue" action
discards previous results and the "merge" action results in an immedate
lookup failure. Consequently, chaining of allocations across modules is
no longer necessary, thus opening up cleanup opportunities.
A test has been added that checks some combinations to ensure that they
work correctly.

commit 849274d48fc59bfa6db3c713c8ced8026b20f3b7
Author: Florian Weimer <fweimer@redhat.com>

elf: Fix force_first handling in dlclose (bug 30981)
The force_first parameter was ineffective because the dlclose'd
object was not necessarily the first in the maps array. Also
enable force_first handling unconditionally, regardless of namespace.
The initial object in a namespace should be destructed first, too.
The _dl_sort_maps_dfs function had early returns for relocation
dependency processing which broke force_first handling, too, and
this is fixed in this change as well.

Subject: manual: add syscalls
The purpose of this patch is to add some system calls that (1) aren't
otherwise documented, and (2) are merely redirected to the kernel, so
can refer to their documentation; and define a standard way of doing
so in the future. A more detailed explaination of how system calls
are wrapped is added along with reference to the Linux Man-Pages
project.

by --with-man-pages=X.Y

Subject: [PATCH] elf: Add a way to check if tunable is set (BZ 27069)
Content-type: text/plain; charset=UTF-8
The patch adds two new macros, TUNABLE_GET_DEFAULT and TUNABLE_IS_INITIALIZED,
here the former get the default value with a signature similar to
TUNABLE_GET, while the later returns whether the tunable was set by
the environment variable.
Checked on x86_64-linux-gnu.

tunables: Terminate if end of input is reached (CVE-2023-4911)
The string parsing routine may end up writing beyond bounds of tunestr
if the input tunable string is malformed, of the form name=name=val.
This gets processed twice, first as name=name=val and next as name=val,
resulting in tunestr being name=name=val:name=val, thus overflowing
tunestr.
Terminate the parsing loop at the first instance itself so that tunestr
does not overflow.
This also fixes up tst-env-setuid-tunables to actually handle failures
correct and add new tests to validate the fix for this CVE.

nscd: Skip unusable entries in first pass in prune_cache (bug 30800)
Previously, if an entry was marked unusable for any reason, but had
not timed out yet, the assert would trigger.
One way to get into such state is if a data change is detected during
re-validation of an entry. This causes the entry to be marked as not
usable. If exits nscd soon after that, then the clock jumps
backwards, and nscd restarted, the cache re-validation run after
startup triggers the removed assert.
The change is more complicated than just the removal of the assert
because entries marked as not usable should be garbage-collected in
the second pass. To make this happen, it is necessary to update some
book-keeping data.

commit 5097cd344fd243fb8deb6dec96e8073753f962f9
Author: Florian Weimer <fweimer@redhat.com>
Date: Thu Aug 1 23:31:30 2024 +0200
elf: Avoid re-initializing already allocated TLS in dlopen (bug 31717)
The old code used l_init_called as an indicator for whether TLS
initialization was complete. However, it is possible that
TLS for an object is initialized, written to, and then dlopen
for this object is called again, and l_init_called is not true at
this point. Previously, this resulted in TLS being initialized
twice, discarding any interim writes (technically introducing a
use-after-free bug even).
This commit introduces an explicit per-object flag, l_tls_in_slotinfo.
It indicates whether _dl_add_to_slotinfo has been called for this
object. This flag is used to avoid double-initialization of TLS.
In update_tls_slotinfo, the first_static_tls micro-optimization
is removed because preserving the initalization flag for subsequent
use by the second loop for static TLS is a bit complicated, and
another per-object flag does not seem to be worth it. Furthermore,
the l_init_called flag is dropped from the second loop (for static
TLS initialization) because l_need_tls_init on its own prevents
double-initialization.
The remaining l_init_called usage in resize_scopes and update_scopes
is just an optimization due to the use of scope_has_map, so it is
not changed in this commit.
The isupper check ensures that libc.so.6 is TLS is not reverted.
Such a revert happens if l_need_tls_init is not cleared in
_dl_allocate_tls_init for the main_thread case, now that
l_init_called is not checked anymore in update_tls_slotinfo
in elf/dl-open.c.

commit df11c05be91fda5ef490c76fd0d4a53821750116
Author: Joseph Myers <josmyers@redhat.com>
Date: Wed Jan 17 15:38:54 2024 +0000
Update syscall lists for Linux 6.7
Linux 6.7 adds the futex_requeue, futex_wait and futex_wake syscalls,
and enables map_shadow_stack for architectures previously missing it.
Update syscall-names.list and regenerate the arch-syscall.h headers
with build-many-glibcs.py update-syscalls.
Tested with build-many-glibcs.py.
Modified for RHEL by: Patsy Griffin <patsy@redhat.com>

commit 3de2f8755c6c036dcd0b1f4acd6bcdefe0e775c0
Author: Joseph Myers <josmyers@redhat.com>
Date: Wed Mar 13 13:57:56 2024 +0000
Update syscall lists for Linux 6.8
Linux 6.8 adds five new syscalls. Update syscall-names.list and
regenerate the arch-syscall.h headers with build-many-glibcs.py
update-syscalls.
Tested with build-many-glibcs.py.
Modified for RHEL by: Patsy Griffin <patsy@redhat.com>

Update syscall lists for Linux 6.9
Linux 6.9 has no new syscalls. Update the version number in
syscall-names.list to reflect that it is still current for 6.9.
Tested with build-many-glibcs.py.

commit 018f0fc3b818d4d1460a4e2384c24802504b1d20
Author: Florian Weimer <fweimer@redhat.com>
Date: Mon Jul 1 17:42:04 2024 +0200
elf: Support recursive use of dynamic TLS in interposed malloc
It turns out that quite a few applications use bundled mallocs that
have been built to use global-dynamic TLS (instead of the recommended
initial-exec TLS). The previous workaround from
commit afe42e935b3ee97bac9a7064157587777259c60e ("elf: Avoid some
free (NULL) calls in _dl_update_slotinfo") does not fix all
encountered cases unfortunatelly.
This change avoids the TLS generation update for recursive use
of TLS from a malloc that was called during a TLS update. This
is possible because an interposed malloc has a fixed module ID and
TLS slot. (It cannot be unloaded.) If an initially-loaded module ID
is encountered in __tls_get_addr and the dynamic linker is already
in the middle of a TLS update, use the outdated DTV, thus avoiding
another call into malloc. It's still necessary to update the
DTV to the most recent generation, to get out of the slow path,
which is why the check for recursion is needed.
The bookkeeping is done using a global counter instead of per-thread
flag because TLS access in the dynamic linker is tricky.
All this will go away once the dynamic linker stops using malloc
for TLS, likely as part of a change that pre-allocates all TLS
during pthread_create/dlopen.
Fixes commit d2123d68275acc0f061e73d5f86ca504e0d5a344 ("elf: Fix slow
tls access after dlopen [BZ #19924]").

+@item EOVERFLOW
+The number of written bytes would have exceeded @code{INT_MAX}, and thus
+could not be represented in the return type @code{int}.
+
+@item ENOMEM
+The function could not allocate memory during processing. Long argument
+lists and certain floating point conversions may require memory
+allocation, as does initialization of an output stream upon first use.
+
+@item EILSEQ
+POSIX specifies this error code should be used if a wide character is
+encountered that does not have a matching valid character. @Theglibc{}
+always performs transliteration, using a replacement character if
+necessary, so this error condition cannot occur on output. However,
+@theglibc{} uses @code{EILSEQ} to indicate that an input character
+sequence (wide or multi-byte) could not be converted successfully.

manual/stdio: Further clarify putc, putwc, getc, and getwc
This is a follow-up to 10de4a47ef3f481592e3c62eb07bcda23e9fde4d that
reworded the manual entries for putc and putwc and removed any
performance claims.
This commit further clarifies these entries and brings getc and getwc in
line with the descriptions of putc and putwc, removing any performance
claims from them as well.

commit 92fdb11ae7aa1ab6b18622670ea702205cd6fdc5
Author: Adhemerval Zanella Netto <adhemerval.zanella@linaro.org>
Date: Tue Feb 28 14:23:59 2023 -0300
powerpc: Remove powerpc64 strncmp variants
The default, and power7 implementation just adds word aligned
access when inputs have the same aligment. The unaligned case
is still done by byte operations.
This is already covered by the generic implementation, which also add
the unaligned input optimization.
Checked on powerpc64-linux-gnu built without multi-arch for powerpc64,
power7, power8, and power9 (build for le).

Date: Mon Dec 19 12:40:45 2022 +0100
getdelim: ensure error indicator is set on error (bug 29917)
POSIX requires that getdelim and getline set the error indicator on the
stream when an error occured, in addition to setting errno.

commit 5456af201d4c0a2950200ba756e5f8314ddbbccd
Author: Carlos O'Donell <carlos@redhat.com>
Date: Thu May 11 14:00:41 2023 -0400
stdio-common: Reformat Makefile.
Reflow Makefile.
Sort using scripts/sort-makefile-lines.py.
Code generation is changed as routines are linked in sorted order
as expected.
No regressions on x86_64 and i686.
(cherry picked from commit c3004417afc98585089a9282d1d4d60cdef5317a)

commit 388c9d7294e5ee3b741aef2e8af63eb1f76ace86
Author: Maciej W. Rozycki <macro@redhat.com>
Date: Fri Jul 26 13:21:34 2024 +0100
support: Add FAIL test failure helper
Add a FAIL test failure helper analogous to FAIL_RET, that does not
cause the current function to return, providing a standardized way to
report a test failure with a message supplied while permitting the
caller to continue executing, for further reporting, cleaning up, etc.
Update existing test cases that provide a conflicting definition of FAIL
by removing the local FAIL definition and then as follows:
- tst-fortify-syslog: provide a meaningful message in addition to the
file name already added by <support/check.h>; 'support_record_failure'
is already called by 'support_print_failure_impl' invoked by the new
FAIL test failure helper.
- tst-ctype: no update to FAIL calls required, with the name of the file
and the line number within of the failure site additionally included
by the new FAIL test failure helper, and error counting plus count
reporting upon test program termination also already provided by
'support_record_failure' and 'support_report_failure' respectively,
called by 'support_print_failure_impl' and 'adjust_exit_status' also
respectively. However in a number of places 'printf' is called and
the error count adjusted by hand, so update these places to make use
of FAIL instead. And last but not least adjust the final summary just
to report completion, with any error count following as reported by
the test driver.
- test-tgmath2: no update to FAIL calls required, with the name of the
file of the failure site additionally included by the new FAIL test
failure helper. Also there is no need to track the return status by
hand as any call to FAIL will eventually cause the test case to return
an unsuccesful exit status regardless of the return status from the
test function, via a call to 'adjust_exit_status' made by the test
driver.

stdio-common: Add test for vfscanf with matches longer than INT_MAX [BZ #27650]
Complement commit b03e4d7bd25b ("stdio: fix vfscanf with matches longer
than INT_MAX (bug 27650)") and add a test case for the issue, inspired
by the reproducer provided with the bug report.
This has been verified to succeed as from the commit referred and fail
beforehand.
As the test requires 2GiB of data to be passed around its performance
has been evaluated using a choice of systems and the execution time
determined to be respectively in the range of 9s for POWER9@2.166GHz,
24s for FU740@1.2GHz, and 40s for 74Kf@950MHz. As this is on the verge
of and beyond the default timeout it has been increased by the factor of
8. Regardless, following recent practice the test has been added to the
standard rather than extended set.
