H.J. Lu	457bd9cf2e	x86-64: Check if mprotect works before rewriting PLT Systemd execution environment configuration may prohibit changing a memory mapping to become executable: MemoryDenyWriteExecute= Takes a boolean argument. If set, attempts to create memory mappings that are writable and executable at the same time, or to change existing memory mappings to become executable, or mapping shared memory segments as executable, are prohibited. When it is set, systemd service stops working if PLT rewrite is enabled. Check if mprotect works before rewriting PLT. This fixes BZ #31230. This also works with SELinux when deny_execmem is on.

Sunil K Pandey	9d94997b5f	x86_64: Optimize ffsll function code size. Ffsll function randomly regress by ~20%, depending on how code gets aligned in memory. Ffsll function code size is 17 bytes. Since default function alignment is 16 bytes, it can load on 16, 32, 48 or 64 bytes aligned memory. When ffsll function load at 16, 32 or 64 bytes aligned memory, entire code fits in single 64 bytes cache line. When ffsll function load at 48 bytes aligned memory, it splits in two cache line, hence random regression. Ffsll function size reduction from 17 bytes to 12 bytes ensures that it will always fit in single 64 bytes cache line. This patch fixes ffsll function random performance regression.

Yanzhang Wang	e0590f41fe	RISC-V: Enable static-pie. This patch referents the commit `374cef3` to add static-pie support. And because the dummy link map is used when relocating ourselves, so need not to set __global_pointer$ at this time. It will also check whether toolchain supports to build static-pie.

Xi Ruoyao	5a85786a90	Make __getrandom_nocancel set errno and add a _nostatus version The __getrandom_nocancel function returns errors as negative values instead of errno. This is inconsistent with other _nocancel functions and it breaks "TEMP_FAILURE_RETRY (__getrandom_nocancel (p, n, 0))" in __arc4random_buf. Use INLINE_SYSCALL_CALL instead of INTERNAL_SYSCALL_CALL to fix this issue. But __getrandom_nocancel has been avoiding from touching errno for a reason, see BZ 29624. So add a __getrandom_nocancel_nostatus function and use it in tcache_key_initialize.

Stefan Liebler	0aabf15a35	resolv: Fix endless loop in __res_context_query Starting with commit `40c0add7d4` "resolve: Remove __res_context_query alloca usage" there is an endless loop in __res_context_query if __res_context_mkquery fails e.g. if type is invalid. Then the scratch buffer is resized to MAXPACKET size and it is retried again. Before the mentioned commit, it was retried only once and with the mentioned commit, there is no check and it retries in an endless loop. This is observable with xtest resolv/tst-resolv-qtypes which times out after 300s. This patch retries mkquery only once as before the mentioned commit. Furthermore, scratch_buffer_set_array_size is now only called with nelem=2 if type is T_QUERY_A_AND_AAAA (also see mentioned commit). The test tst-resolv-qtypes is also adjusted to verify that <func> is really returning with -1 in case of an invalid type. Reviewed-by: Adhemerval Zanella <adhemerval.zanella@linaro.org>	2 years ago

Carlos O'Donell	94aa256a47	elf: Fix tst-nodeps2 test failure. After `78ca44da01` ("elf: Relocate libc.so early during startup and dlmopen (bug 31083)") we start seeing tst-nodeps2 failures when building the testsuite with --enable-hard-coded-path-in-tests. When building the testsuite with --enable-hard-coded-path-in-tests the tst-nodeps2-mod.so is not built with the required DT_RUNPATH values and the test escapes the test framework and loads the system libraries and aborts.

Adhemerval Zanella	460860f457	Remove ia64-linux-gnu Linux 6.7 removed ia64 from the official tree [1], following the general principle that a glibc port needs upstream support for the architecture in all the components it depends on (binutils, GCC, and the Linux kernel). Apart from the removal of sysdeps/ia64 and sysdeps/unix/sysv/linux/ia64, there are updates to various comments referencing ia64 for which removal of those references seemed appropriate. The configuration is removed from README and build-many-glibcs.py. The CONTRIBUTED-BY, elf/elf.h, manual/contrib.texi (the porting mention), *.po files, config.guess, and longlong.h are not changed. For Linux it allows cleanup some clone2 support on multiple files. The following bug can be closed as WONTFIX: BZ 22634 [2], BZ 14250 [3], BZ 21634 [4], BZ 10163 [5], BZ 16401 [6], and BZ 11585 [7].
