commit 9831f98c266a8d56d1bf729b709c08e40375540c
Author: Florian Weimer <fweimer@redhat.com>
Date: Fri Apr 19 14:38:17 2024 +0200
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.

commit 836d43b98973e0845b739ff5d3aad3af09dc7d0f
Author: Florian Weimer <fweimer@redhat.com>
Date: Fri Apr 19 14:38:17 2024 +0200
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).

commit 273a835fe7c685cc54266bb8b502787bad5e9bae
Author: Carlos O'Donell <carlos@redhat.com>
Date: Tue Apr 23 13:30:37 2024 -0400
time: Allow later version licensing.
The FSF's Licensing and Compliance Lab noted a discrepancy in the
licensing of several files in the glibc package.
When timespect_get.c was impelemented the license did not include
the standard ", or (at your option) any later version." text.
Change the license in timespec_get.c and all copied files to match
the expected license.
This change was previously approved in principle by the FSF in
RT ticket #1316403. And a similar instance was fixed in
commit 46703efa02f6ddebce5ee54c92f7c32598de0de6.

that memcpy and mempcpy won't pull in __chk_fail and the routines it

i686: Fix multiple definitions of __memmove_chk and __memset_chk
Commit c73c96a4a1af1326df7f96eec58209e1e04066d8 updated memcpy.S and
mempcpy.S, but omitted memmove.S and memset.S. As a result, the static
library built as PIC, whether with or without multiarch support,
contains two definitions for each of the __memmove_chk and __memset_chk
symbols.

After this change, regardless of PIC options, the static library, built
for i686 with multiarch contains implementations of these functions
respectively from debug/memmove_chk.c and debug/memset_chk.c, and
without multiarch contains implementations of these functions
respectively from sysdeps/i386/memmove_chk.S and
sysdeps/i386/memset_chk.S. This ensures that memmove and memset won't
pull in __chk_fail and the routines it calls.

Add a test to check for duplicate definitions in the static library
This change follows two previous fixes addressing multiple definitions
of __memcpy_chk and __mempcpy_chk functions on i586, and __memmove_chk
and __memset_chk functions on i686. The test is intended to prevent
such issues from occurring in the future.

that memcpy and mempcpy won't pull in __chk_fail and the routines it
calls.

i686: Fix multiple definitions of __memmove_chk and __memset_chk
Commit c73c96a4a1af1326df7f96eec58209e1e04066d8 updated memcpy.S and
mempcpy.S, but omitted memmove.S and memset.S. As a result, the static
library built as PIC, whether with or without multiarch support,
contains two definitions for each of the __memmove_chk and __memset_chk
symbols.

After this change, regardless of PIC options, the static library, built
for i686 with multiarch contains implementations of these functions

without multiarch contains implementations of these functions
respectively from sysdeps/i386/memmove_chk.S and
sysdeps/i386/memset_chk.S. This ensures that memmove and memset won't

Add a test to check for duplicate definitions in the static library
This change follows two previous fixes addressing multiple definitions
of __memcpy_chk and __mempcpy_chk functions on i586, and __memmove_chk
and __memset_chk functions on i686. The test is intended to prevent
such issues from occurring in the future.

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.

Force DT_RPATH for --enable-hardcoded-path-in-tests
On Fedora 40/x86-64, linker enables --enable-new-dtags by default which
generates DT_RUNPATH instead of DT_RPATH. Unlike DT_RPATH, DT_RUNPATH
only applies to DT_NEEDED entries in the executable and doesn't applies
to DT_NEEDED entries in shared libraries which are loaded via DT_NEEDED
entries in the executable. Some glibc tests have libstdc++.so.6 in
DT_NEEDED, which has libm.so.6 in DT_NEEDED. When DT_RUNPATH is generated,
/lib64/libm.so.6 is loaded for such tests. If the newly built glibc is
older than glibc 2.36, these tests fail with
assert/tst-assert-c++: /export/build/gnu/tools-build/glibc-gitlab-release/build-x86_64-linux/libc.so.6: version `GLIBC_2.36' not found (required by /lib64/libm.so.6)

Pass -Wl,--disable-new-dtags to linker when building glibc tests with
--enable-hardcoded-path-in-tests. This fixes BZ #31719.
