* Remove "Contributed by" linesSiddhesh Poyarekar2021-09-031-1/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | We stopped adding "Contributed by" or similar lines in sources in 2012 in favour of git logs and keeping the Contributors section of the glibc manual up to date. Removing these lines makes the license header a bit more consistent across files and also removes the possibility of error in attribution when license blocks or files are copied across since the contributed-by lines don't actually reflect reality in those cases. Move all "Contributed by" and similar lines (Written by, Test by, etc.) into a new file CONTRIBUTED-BY to retain record of these contributions. These contributors are also mentioned in manual/contrib.texi, so we just maintain this additional record as a courtesy to the earlier developers. The following scripts were used to filter a list of files to edit in place and to clean up the CONTRIBUTED-BY file respectively. These were not added to the glibc sources because they're not expected to be of any use in future given that this is a one time task: https://gist.github.com/siddhesh/b5ecac94eabfd72ed2916d6d8157e7dc https://gist.github.com/siddhesh/15ea1f5e435ace9774f485030695ee02 Reviewed-by: Carlos O'Donell <carlos@redhat.com>

* 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.

In most cases, there are no errors. But we still call __x86.get_pc_thunk.reg. This patch adds INLINE_SYSCALL_ERROR_RETURN_VALUE so that i386 can optimize setting errno by branching to the internal __syscall_error without PLT. With i386 INLINE_SYSCALL_ERROR_RETURN_VALUE and i386 syscall inlining optimization for GCC 5, for sysdeps/unix/sysv/linux/fchmodat.c with -O2 -march=i686 -mtune=generic, GCC 5.2 now generates: <fchmodat>: 0: push %ebx 1: mov 0x14(%esp),%eax 5: mov 0x8(%esp),%ebx 9: mov 0xc(%esp),%ecx d: mov 0x10(%esp),%edx 11: test $0xfffffeff,%eax 16: jne 38 <fchmodat+0x38> 18: test $0x1,%ah 1b: jne 48 <fchmodat+0x48> 1d: mov $0x132,%eax 22: call *%gs:0x10 29: cmp $0xfffff000,%eax 2e: ja 58 <fchmodat+0x58> 30: pop %ebx 31: ret 32: lea 0x0(%esi),%esi 38: pop %ebx 39: mov $0xffffffea,%eax 3e: jmp 3f <fchmodat+0x3f> 3f: R_386_PC32 __syscall_error 43: nop 44: lea 0x0(%esi,%eiz,1),%esi 48: pop %ebx 49: mov $0xffffffa1,%eax 4e: jmp 4f <fchmodat+0x4f> 4f: R_386_PC32 __syscall_error 53: nop 54: lea 0x0(%esi,%eiz,1),%esi 58: pop %ebx 59: jmp 5a <fchmodat+0x5a> 5a: R_386_PC32 __syscall_error instead of <fchmodat>: 0: sub $0x8,%esp 3: mov 0x18(%esp),%eax 7: mov %ebx,(%esp) a: call b <fchmodat+0xb> b: R_386_PC32 __x86.get_pc_thunk.bx f: add $0x2,%ebx 11: R_386_GOTPC _GLOBAL_OFFSET_TABLE_ 15: mov %edi,0x4(%esp) 19: test $0xfffffeff,%eax 1e: jne 70 <fchmodat+0x70> 20: test $0x1,%ah 23: jne 88 <fchmodat+0x88> 25: mov 0x14(%esp),%edx 29: mov 0x10(%esp),%ecx 2d: mov 0xc(%esp),%edi 31: xchg %ebx,%edi 33: mov $0x132,%eax 38: call *%gs:0x10 3f: xchg %edi,%ebx 41: cmp $0xfffff000,%eax 46: ja 58 <fchmodat+0x58> 48: mov (%esp),%ebx 4b: mov 0x4(%esp),%edi 4f: add $0x8,%esp 52: ret 53: nop 54: lea 0x0(%esi,%eiz,1),%esi 58: mov 0x0(%ebx),%edx 5a: R_386_TLS_GOTIE __libc_errno 5e: neg %eax 60: mov %eax,%gs:(%edx) 63: mov $0xffffffff,%eax 68: jmp 48 <fchmodat+0x48> 6a: lea 0x0(%esi),%esi 70: mov 0x0(%ebx),%eax 72: R_386_TLS_GOTIE __libc_errno 76: movl $0x16,%gs:(%eax) 7d: mov $0xffffffff,%eax 82: jmp 48 <fchmodat+0x48> 84: lea 0x0(%esi,%eiz,1),%esi 88: mov 0x0(%ebx),%eax 8a: R_386_TLS_GOTIE __libc_errno 8e: movl $0x5f,%gs:(%eax) 95: mov $0xffffffff,%eax 9a: jmp 48 <fchmodat+0x48> * sysdeps/unix/sysv/linux/sysdep.h: New file. * sysdeps/unix/sysv/linux/i386/sysdep.c: Likewise. * sysdeps/unix/sysv/linux/alpha/sysdep.h: Include <sysdeps/unix/sysv/linux/sysdep.h>. * sysdeps/unix/sysv/linux/arm/sysdep.h: Likewise. * sysdeps/unix/sysv/linux/generic/sysdep.h: Likewise. * sysdeps/unix/sysv/linux/hppa/sysdep.h: Likewise. * sysdeps/unix/sysv/linux/ia64/sysdep.h: Likewise. * sysdeps/unix/sysv/linux/m68k/sysdep.h: Likewise. * sysdeps/unix/sysv/linux/microblaze/sysdep.h: Likewise. * sysdeps/unix/sysv/linux/mips/mips32/sysdep.h: Likewise. * sysdeps/unix/sysv/linux/mips/mips64/n32/sysdep.h: Likewise. * sysdeps/unix/sysv/linux/mips/mips64/n64/sysdep.h: Likewise. * sysdeps/unix/sysv/linux/powerpc/powerpc32/sysdep.h: Likewise. * sysdeps/unix/sysv/linux/powerpc/powerpc64/sysdep.h: Likewise. * sysdeps/unix/sysv/linux/s390/s390-32/sysdep.h: Likewise. * sysdeps/unix/sysv/linux/s390/s390-64/sysdep.h: Likewise. * sysdeps/unix/sysv/linux/sh/sysdep.h: Likewise. * sysdeps/unix/sysv/linux/sparc/sysdep.h: Likewise. * sysdeps/unix/sysv/linux/x86_64/sysdep.h: Likewise. * sysdeps/unix/sysv/linux/i386/Makefile [$(subdir) == csu] (sysdep-dl-routines): Add sysdep.
