- Update to glibc 2.40
  * The <stdbit.h> header type-generic macros have been changed when using
    GCC 14.1 or later to use __builtin_stdc_bit_ceil etc. built-in functions
  * The GNU C Library now supports a feature test macro _ISOC23_SOURCE to
    enable features from the ISO C23 standard
  * The ISO C23 function families introduced in TS
    18661-4:2015 are now supported in <math.h>
  * A new tunable, glibc.rtld.enable_secure, can be used to run a program
    as if it were a setuid process
  * On Linux, the epoll header was updated to include epoll ioctl definitions
    and the related structure added in Linux kernel 6.9
  * The fortify functionality has been significantly enhanced for building
    programs with clang against the GNU C Library
  * Many functions have been added to the vector library for aarch64
  * On x86, memset can now use non-temporal stores to improve the performance
    of large writes
  * Architectures which use a 32-bit seconds-since-epoch field in struct
    lastlog, struct utmp, struct utmpx (such as i386, powerpc64le, rv32,
    rv64, x86-64) switched from a signed to an unsigned type for that
    field
  * __rseq_size now denotes the size of the active rseq area (20 bytes
    initially), not the size of struct rseq (32 bytes initially).

Subject: [PATCH] arm: Remove wrong ldr from _dl_start_user (BZ 31339)
The commit 49d877a80b29d3002887b084eec6676d9f5fec18 (arm: Remove
_dl_skip_args usage) removed the _SKIP_ARGS literal, which was
previously loader to r4 on loader _start. However, the cleanup did not
remove the following 'ldr r4, [sl, r4]' on _dl_start_user, used to check
to skip the arguments after ld self-relocations.
In my testing, the kernel initially set r4 to 0, which makes the
ldr instruction just read the _GLOBAL_OFFSET_TABLE_. However, since r4
is a callee-saved register; a different runtime might not zero
initialize it and thus trigger an invalid memory access.
Checked on arm-linux-gnu.

Subject: [PATCH] duplocale: protect use of global locale (bug 23970)
Protect the global locale from being modified while we compute the size of
the locale category names. That allows the use of the global locale in a
single thread, while all other threads use the thread safe locale
functions.

Subject: [PATCH] elf: Only process multiple tunable once (BZ 31686)
The 680c597e9c3 commit made loader reject ill-formatted strings by
first tracking all set tunables and then applying them. However, it does
not take into consideration if the same tunable is set multiple times,
where parse_tunables_string appends the found tunable without checking
if it was already in the list. It leads to a stack-based buffer overflow
if the tunable is specified more than the total number of tunables. For
instance:
GLIBC_TUNABLES=glibc.malloc.check=2:... (repeat over the number of
total support for different tunable).
Instead, use the index of the tunable list to get the expected tunable
entry. Since now the initial list is zero-initialized, the compiler
might emit an extra memset and this requires some minor adjustment
on some ports.
Checked on x86_64-linux-gnu and aarch64-linux-gnu.

Subject: [PATCH] CVE-2024-33600: nscd: Avoid null pointer crashes after
notfound response (bug 31678)
The addgetnetgrentX call in addinnetgrX may have failed to produce
a result, so the result variable in addinnetgrX can be NULL.
Use db->negtimeout as the fallback value if there is no result data;
the timeout is also overwritten below.
Also avoid sending a second not-found response. (The client
disconnects after receiving the first response, so the data stream did
not go out of sync even without this fix.) It is still beneficial to
add the negative response to the mapping, so that the client can get
it from there in the future, instead of going through the socket.

Subject: [PATCH] CVE-2024-33600: nscd: Do not send missing not-found response
in addgetnetgrentX (bug 31678)
If we failed to add a not-found response to the cache, the dataset
point can be null, resulting in a null pointer dereference.

Subject: [PATCH] CVE-2024-33601, CVE-2024-33602: nscd: netgroup: Use two
buffers in addgetnetgrentX (bug 31680)
This avoids potential memory corruption when the underlying NSS
callback function does not use the buffer space to store all strings
(e.g., for constant strings).
Instead of custom buffer management, two scratch buffers are used.
This increases stack usage somewhat.
Scratch buffer allocation failure is handled by return -1
(an invalid timeout value) instead of terminating the process.
This fixes bug 31679.

Mon Jul 29 07:50:31 UTC 2024 - Andreas Schwab <schwab@suse.de>
- Update to glibc 2.40
* The <stdbit.h> header type-generic macros have been changed when using
GCC 14.1 or later to use __builtin_stdc_bit_ceil etc. built-in functions
* The GNU C Library now supports a feature test macro _ISOC23_SOURCE to
enable features from the ISO C23 standard
* The ISO C23 function families introduced in TS
18661-4:2015 are now supported in <math.h>
* A new tunable, glibc.rtld.enable_secure, can be used to run a program
as if it were a setuid process
* On Linux, the epoll header was updated to include epoll ioctl definitions
and the related structure added in Linux kernel 6.9
* The fortify functionality has been significantly enhanced for building
programs with clang against the GNU C Library
* Many functions have been added to the vector library for aarch64
* On x86, memset can now use non-temporal stores to improve the performance
of large writes
* Architectures which use a 32-bit seconds-since-epoch field in struct
lastlog, struct utmp, struct utmpx (such as i386, powerpc64le, rv32,
rv64, x86-64) switched from a signed to an unsigned type for that
field
* __rseq_size now denotes the size of the active rseq area (20 bytes
initially), not the size of struct rseq (32 bytes initially).

Subject: [PATCH] iconv: ISO-2022-CN-EXT: fix out-of-bound writes when writing
escape sequence (CVE-2024-2961)
ISO-2022-CN-EXT uses escape sequences to indicate character set changes
(as specified by RFC 1922). While the SOdesignation has the expected
bounds checks, neither SS2designation nor SS3designation have its;
allowing a write overflow of 1, 2, or 3 bytes with fixed values:
'$+I', '$+J', '$+K', '$+L', '$+M', or '$*H'.
Checked on aarch64-linux-gnu.

Subject: [PATCH] S390: Do not clobber r7 in clone [BZ #31402]
Starting with commit e57d8fc97b90127de4ed3e3a9cdf663667580935
"S390: Always use svc 0"
clone clobbers the call-saved register r7 in error case:
function or stack is NULL.
This patch restores the saved registers also in the error case.
Furthermore the existing test misc/tst-clone is extended to check
all error cases and that clone does not clobber registers in this
error case.

Subject: [PATCH] linux/sigsetops: fix type confusion (bug 31468)
Each mask in the sigset array is an unsigned long, so fix __sigisemptyset
to use that instead of int. The __sigword function returns a simple array
index, so it can return int instead of unsigned long.

Subject: [PATCH] login: Check default sizes of structs utmp, utmpx, lastlog
The default <utmp-size.h> is for ports with a 64-bit time_t.
Ports with a 32-bit time_t or with __WORDSIZE_TIME64_COMPAT32=1
need to override it.

Subject: [PATCH] login: structs utmp, utmpx, lastlog _TIME_BITS independence
(bug 30701)
These structs describe file formats under /var/log, and should not
depend on the definition of _TIME_BITS. This is achieved by
defining __WORDSIZE_TIME64_COMPAT32 to 1 on 32-bit ports that
support 32-bit time_t values (where __time_t is 32 bits).
