linux: Add support for getrandom vDSO
Linux 6.11 has getrandom() in vDSO. It operates on a thread-local opaque state allocated with mmap using flags specified by the vDSO. Multiple states are allocated at once, as many as fit into a page, and these are held in an array of available states to be doled out to each thread upon first use, and recycled when a thread terminates. As these states run low, more are allocated. To make this procedure async-signal-safe, a simple guard is used in the LSB of the opaque state address, falling back to the syscall if there's reentrancy contention. Also, _Fork() is handled by blocking signals on opaque state allocation (so _Fork() always sees a consistent state even if it interrupts a getrandom() call) and by iterating over the thread stack cache on reclaim_stack. Each opaque state will be in the free states list (grnd_alloc.states) or allocated to a running thread. The cancellation is handled by always using GRND_NONBLOCK flags while calling the vDSO, and falling back to the cancellable syscall if the kernel returns EAGAIN (would block). Since getrandom is not defined by POSIX and cancellation is supported as an extension, the cancellation is handled as 'may occur' instead of 'shall occur' [1], meaning that if vDSO does not block (the expected behavior) getrandom will not act as a cancellation entrypoint. It avoids a pthread_testcancel call on the fast path (different than 'shall occur' functions, like sem_wait()). It is currently enabled for x86_64, which is available in Linux 6.11, and aarch64, powerpc32, powerpc64, loongarch64, and s390x, which are available in Linux 6.12.

S390: Always use svc 0
On s390x syscalls are triggered by svc instruction. One can pass the syscall number encoded in the instruction "svc 123" or by storing it in r1: lghi r1,123 svc 0 If the syscall number is encoded in the instruction, this can cause broken syscall restarts. Therefore this patch is now just passing the syscall number in r1. See also kernel-commit: "s390/signal: switch to using vdso for sigreturn and syscall restart" https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/arch/s390/[%e2%80%a6]call.c?h=v6.0-rc1&id=df29a7440c4b5c65765c8f60396b3b13063e24e9 As information, the "svc 0" feature was introduced in kernel 2.5.62: commit b5aad611393ef2e132e3648fa4c6e56a9cfa8708 |

Replace __libc_multiple_threads with __libc_single_threaded
And also fixes the SINGLE_THREAD_P macro for SINGLE_THREAD_BY_GLOBAL, since header inclusion single-thread.h is in the wrong order, the define needs to come before including sysdeps/unix/sysdep.h. The macro is now moved to a per-arch single-threade.h header. The SINGLE_THREAD_P is used on some more places. Checked on aarch64-linux-gnu and x86_64-linux-gnu. |

Update copyright dates with scripts/update-copyrights
I used these shell commands: ../glibc/scripts/update-copyrights $PWD/../gnulib/build-aux/update-copyright (cd ../glibc && git commit -am"[this commit message]") and then ignored the output, which consisted lines saying "FOO: warning: copyright statement not found" for each of 7061 files FOO. I then removed trailing white space from math/tgmath.h, support/tst-support-open-dev-null-range.c, and sysdeps/x86_64/multiarch/strlen-vec.S, to work around the following obscure pre-commit check failure diagnostics from Savannah. I don't know why I run into these diagnostics whereas others evidently do not. remote: *** 912-#endif remote: *** 913: remote: *** 914- remote: *** error: lines with trailing whitespace found ... remote: *** error: sysdeps/unix/sysv/linux/statx_cp.c: trailing lines |

linux: Remove INTERNAL_SYSCALL_DECL
With all Linux ABIs using the expected Linux kABI to indicate syscalls errors, the INTERNAL_SYSCALL_DECL is an empty declaration on all ports. This patch removes the 'err' argument on INTERNAL_SYSCALL* macro and remove the INTERNAL_SYSCALL_DECL usage. Checked with a build against all affected ABIs. |

linux: Consolidate INLINE_SYSCALL
With all Linux ABIs using the expected Linux kABI to indicate syscalls errors, there is no need to replicate the INLINE_SYSCALL. The generic Linux sysdep.h includes errno.h even for !__ASSEMBLER__, which is ok now and it allows cleanup some archaic code that assume otherwise. Checked with a build against all affected ABIs. |

Refactor vDSO initialization code
Linux vDSO initialization code the internal function pointers require a
lot of duplicated boilerplate over different architectures. This patch
aims to simplify not only the code but the required definition to enable
a vDSO symbol.
The changes are:
1. Consolidate all init-first.c on only one implementation and enable
the symbol based on HAVE_*_VSYSCALL existence.
2. Set the HAVE_*_VSYSCALL to the architecture expected names string.
3. Add a new internal implementation, get_vdso_mangle_symbol, which
returns a mangled function pointer.
Currently the clock_gettime, clock_getres, gettimeofday, getcpu, and time
are handled in an arch-independent way, powerpc still uses some
arch-specific vDSO symbol handled in a specific init-first implementation.
Checked on aarch64-linux-gnu, arm-linux-gnueabihf, i386-linux-gnu,

Remove PREPARE_VERSION and PREPARE_VERSION_KNOW
This patch removes the PREPARE_VERSION and PREPARE_VERSION_KNOW macro and uses a static inline function instead, get_vdso_symbol. Each architecture that supports vDSO must define the Linux version and its hash for symbol resolution (VDSO_NAME and VDSO_HASH macro respectively). It also organizes the HAVE_*_VSYSCALL for mips, powerpc, and s390 to define them on a common header. The idea is to require less code to configure and enable vDSO support for newer ports. No semantic changes are expected. Checked with a build against all affected architectures. * sysdeps/unix/make-syscalls.sh: Make vDSO call use get_vdso_symbol. * sysdeps/unix/sysv/linux/aarch64/gettimeofday.c (__gettimeofday): Use get_vdso_symbol instead of _dl_vdso_vsym. * sysdeps/unix/sysv/linux/powerpc/time.c (time): Likewise. * sysdeps/unix/sysv/linux/riscv/flush-icache.c (__lookup_riscv_flush_icache): Likewise. * sysdeps/unix/sysv/linux/x86/gettimeofday.c (__gettimeofday): Likewise. * sysdeps/unix/sysv/linux/x86/time.c (time): Likewise. * sysdeps/unix/sysv/linux/powerpc/gettimeofday.c: Likewise. * sysdeps/unix/sysv/linux/aarch64/init-first.c: Likewise. * sysdeps/unix/sysv/linux/arm/init-first.c: Likewise. * sysdeps/unix/sysv/linux/i386/init-first.c: Likewise. * sysdeps/unix/sysv/linux/mips/init-first.c: Likewise. * sysdeps/unix/sysv/linux/powerpc/init-first.c: Likewise. * sysdeps/unix/sysv/linux/riscv/init-first.c: Likewise. * sysdeps/unix/sysv/linux/sparc/init-first.c: Likewise. * sysdeps/unix/sysv/linux/s390/init-first.c: Likewise. * sysdeps/unix/sysv/linux/x86_64/init-first.c: Likewise. * sysdeps/unix/sysv/linux/aarch64/sysdep.h (VDSO_NAME, VDSO_HASH): Define. * sysdeps/unix/sysv/linux/arm/sysdep.h (VDSO_NAME, VDSO_HASH): Likewise. * sysdeps/unix/sysv/linux/i386/sysdep.h (VDSO_NAME, VDSO_HASH): Likewise. * sysdeps/unix/sysv/linux/riscv/sysdep.h (VDSO_NAME, VDSO_HASH): Likewise. * sysdeps/unix/sysv/linux/sparc/sysdep.h (VDSO_NAME, VDSO_HASH): Likewise. * sysdeps/unix/sysv/linux/x86_64/sysdep.h (VDSO_NAME, VDSO_HASH): Likewise. * sysdeps/unix/sysv/linux/mips/mips32/sysdep.h (HAVE_CLOCK_GETTIME_VSYSCALL, HAVE_GETTIMEOFDAY_VSYSCALL): Remove definition. * sysdeps/unix/sysv/linux/mips/mips64/n32/sysdep.h (HAVE_CLOCK_GETTIME_VSYSCALL, HAVE_GETTIMEOFDAY_VSYSCALL): Likewise. * sysdeps/unix/sysv/linux/mips/mips64/n64/sysdep.h (HAVE_CLOCK_GETTIME_VSYSCALL, HAVE_GETTIMEOFDAY_VSYSCALL): Likewise. * sysdeps/unix/sysv/linux/powerpc/powerpc32/sysdep.h (HAVE_CLOCK_GETTIME_VSYSCALL, HAVE_GETTIMEOFDAY_VSYSCALL): Likewise. * sysdeps/unix/sysv/linux/powerpc/powerpc64/sysdep.h (HAVE_CLOCK_GETTIME_VSYSCALL, HAVE_GETTIMEOFDAY_VSYSCALL): Likewise. * sysdeps/unix/sysv/linux/s390/s390-32/sysdep.h (HAVE_CLOCK_GETRES_VSYSCALL, HAVE_CLOCK_GETTIME_VSYSCALL, HAVE_GETTIMEOFDAY_VSYSCALL, HAVE_GETCPU_VSYSCALL): Likewise. * sysdeps/unix/sysv/linux/s390/s390-64/sysdep.h (HAVE_CLOCK_GETRES_VSYSCALL, HAVE_CLOCK_GETTIME_VSYSCALL, HAVE_GETTIMEOFDAY_VSYSCALL, HAVE_GETCPU_VSYSCALL): Likewise. * sysdeps/unix/sysv/linux/mips/sysdep.h: New file. * sysdeps/unix/sysv/linux/powerpc/sysdep.h: Likewise. * sysdeps/unix/sysv/linux/s390/sysdep.h: Likewise. * sysdeps/unix/sysv/linux/dl-vdso.h (PREPARE_VERSION, PREPARE_VERSION_KNOWN, VDSO_NAME_LINUX_2_6, VDSO_HASH_LINUX_2_6, VDSO_NAME_LINUX_2_6_15, VDSO_HASH_LINUX_2_6_15, VDSO_NAME_LINUX_2_6_29, VDSO_HASH_LINUX_2_6_29, VDSO_NAME_LINUX_4_15, VDSO_HASH_LINUX_4_15): Remove defines.
