* Update copyright dates with scripts/update-copyrightsPaul Eggert2021-01-021-1/+1
| | | | | | | | | | | | | | | | 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 6694 files FOO. I then removed trailing white space from benchtests/bench-pthread-locks.c and iconvdata/tst-iconv-big5-hkscs-to-2ucs4.c, to work around this diagnostic from Savannah: remote: *** pre-commit check failed ... remote: *** error: lines with trailing whitespace found remote: error: hook declined to update refs/heads/master
* linux: Remove INTERNAL_SYSCALL_DECLAdhemerval Zanella2020-02-141-11/+11
| | | | | | | | | | | 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_SYSCALLAdhemerval Zanella2020-02-141-22/+0
| | | | | | | | | | | 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.
* sparc: Avoid clobbering register parameters in syscallAdhemerval Zanella2020-02-141-27/+53
| | | | | | | | | | | | | | The sparc INTERNAL_SYSCALL macro might clobber the register parameter if the argument itself might clobber any register (a function call for instance). This patch fixes it by using temporary variables for the expressions between the register assignments (as indicated by GCC documentation, 6.47.5.2 Specifying Registers for Local Variables). It is similar to the fix done for MIPS (bug 25523). Checked on sparc64-linux-gnu and sparcv9-linux-gnu.
* sparc: Use Linux kABI for syscall returnAdhemerval Zanella2020-02-141-44/+36
| | | | | | | | | | | | | | | | | It changes the sparc internal_syscall* macros to return a negative value instead of the 'g1' register value in the 'err' macro argument. The __SYSCALL_STRING macro is also changed to no set the 'g1' value, since 'o1' already holds all the required information to check if syscall has failed. The macro INTERNAL_SYSCALL_DECL is no longer required, and the INTERNAL_SYSCALL_ERROR_P macro follows the other Linux kABIs. The redefinition of INTERNAL_VSYSCALL_CALL is also no longer required. Checked on sparc64-linux-gnu and sparcv9-linux-gnu. It fixes the sporadic issues on sparc32 where clock_nanosleep does not act as cancellation entrypoint.
* linux: Add support for clock_gettime64 vDSOAdhemerval Zanella2020-01-031-1/+5
| | | | | | | | No architecture currently defines the vDSO symbol. On architectures with 64-bit time_t the HAVE_CLOCK_GETTIME_VSYSCALL is renamed to HAVE_CLOCK_GETTIME64_VSYSCALL, it simplifies clock_gettime code. Reviewed-by: Siddhesh Poyarekar <siddhesh@sourceware.org>

* Refactor vDSO initialization codeAdhemerval Zanella2019-09-171-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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, mips64-linux-gnu, powerpc64le-linux-gnu, s390x-linux-gnu, sparc64-linux-gnu, and x86_64-linux-gnu. * sysdeps/powerpc/powerpc32/backtrace.c (is_sigtramp_address, is_sigtramp_address_rt): Use HAVE_SIGTRAMP_{RT}32 instead of SHARED. * sysdeps/powerpc/powerpc64/backtrace.c (is_sigtramp_address): Likewise. * sysdeps/unix/sysv/linux/aarch64/init-first.c: Remove file. * sysdeps/unix/sysv/linux/aarch64/libc-vdso.h: Likewise. * sysdeps/unix/sysv/linux/arm/init-first.c: Likewise. * sysdeps/unix/sysv/linux/arm/libc-vdso.h: Likewise. * sysdeps/unix/sysv/linux/mips/init-first.c: Likewise. * sysdeps/unix/sysv/linux/mips/libc-vdso.h: Likewise. * sysdeps/unix/sysv/linux/i386/init-first.c: Likewise. * sysdeps/unix/sysv/linux/riscv/init-first.c: Likewise. * sysdeps/unix/sysv/linux/riscv/libc-vdso.h: Likewise. * sysdeps/unix/sysv/linux/s390/init-first.c: Likewise. * sysdeps/unix/sysv/linux/s390/libc-vdso.h: Likewise. * sysdeps/unix/sysv/linux/sparc/init-first.c: Likewise. * sysdeps/unix/sysv/linux/sparc/libc-vdso.h: Likewise. * sysdeps/unix/sysv/linux/x86/libc-vdso.h: Likewise. * sysdeps/unix/sysv/linux/x86_64/init-first.c: Likewise. * sysdeps/unix/sysv/linux/aarch64/sysdep.h (HAVE_CLOCK_GETRES_VSYSCALL, HAVE_CLOCK_GETTIME_VSYSCALL, HAVE_GETTIMEOFDAY_VSYSCALL): Define value based on kernel exported name. * sysdeps/unix/sysv/linux/arm/sysdep.h (HAVE_CLOCK_GETTIME_VSYSCALL, HAVE_GETTIMEOFDAY_VSYSCALL): Likewise. * sysdeps/unix/sysv/linux/i386/sysdep.h (HAVE_CLOCK_GETTIME_VSYSCALL, HAVE_GETTIMEOFDAY_VSYSCALL): Likewise. * sysdeps/unix/sysv/linux/mips/sysdep.h (HAVE_CLOCK_GETTIME_VSYSCALL, HAVE_GETTIMEOFDAY_VSYSCALL): Likewise. * sysdeps/unix/sysv/linux/powerpc/sysdep.h (HAVE_CLOCK_GETRES_VSYSCALL, HAVE_CLOCK_GETTIME_VSYSCALL, HAVE_GETCPU_VSYSCALL, HAVE_TIME_VSYSCALL, HAVE_GET_TBFREQ, HAVE_SIGTRAMP_RT64, HAVE_SIGTRAMP_32, HAVE_SIGTRAMP_RT32i, HAVE_GETTIMEOFDAY_VSYSCALL): Likewise. * sysdeps/unix/sysv/linux/riscv/sysdep.h (HAVE_CLOCK_GETRES_VSYSCALL, HAVE_CLOCK_GETTIME_VSYSCALL, HAVE_GETTIMEOFDAY_VSYSCALL, HAVE_GETCPU_VSYSCALL): Likewise. * sysdeps/unix/sysv/linux/s390/sysdep.h (HAVE_CLOCK_GETRES_VSYSCALL, HAVE_CLOCK_GETTIME_VSYSCALL, HAVE_GETTIMEOFDAY_VSYSCALL, HAVE_GETCPU_VSYSCALL): Likewise. * sysdeps/unix/sysv/linux/sparc/sysdep.h (HAVE_CLOCK_GETTIME_VSYSCALL, HAVE_GETTIMEOFDAY_VSYSCALL): Likewise. * sysdeps/unix/sysv/linux/x86_64/sysdep.h (HAVE_CLOCK_GETTIME_VSYSCALL, HAVE_GETTIMEOFDAY_VSYSCALL, HAVE_GETCPU_VSYSCALL): Likewise. * sysdeps/unix/sysv/linux/dl-vdso.h (VDSO_NAME, VDSO_HASH): Define to invalid names if architecture does not define them.

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.

* linux: Enable vDSO for static linking as default (BZ#19767)Adhemerval Zanella2019-08-051-3/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch assumes static vDSO is supported as default, it is now supported on all current architectures that support vDSO.
