2024-04-18Generalize vDSO code.Dmitry Chestnykh
- Add macroses for vDSO functions names because in some architectures these names differ from the default ones. - Add header guards in dl-syscalls.h . Signed-off-by: Dmitry Chestnykh <dm.chestnykh@gmail.com>
2024-04-18Fix vDSO support for all supported architectures.Dmitry Chestnykh
- Cleanup dl-vdso.c code. - Pass `void *` as first arg to `load_vdso()`, using 32-bit type is completely wrong on 64bit architectures. - Split libc code and vDSO-related code. Move arch-specific implementations into separate files. The performance improvement is for example 50-60 times on ARMv7 and about 4 times on x86_64.

2024-04-14libuargp: restrict compatibility macros in argp.h onlyYao Zi
Macros __attribute__, __format__ and __printf__ are defined in argp.h for compatibility with ANSI and old gccs. But leaving them effective out of the scope of the header may break applications relying on these compiler attributes even with __STRICT_ANSI__ defined. So undef the macros after using.

2024-04-13Provide fixups for riscv32.Dmitry Chestnykh
- Use TIME64 by default for rv32, usage of 32-bit time leads to a lot of incompatibilities with linux kernel 6.6.x and later versions. - Add some other corrections to use proper system calls on riscv32 platform. Signed-off-by: Dmitry Chestnykh <dm.chestnykh@gmail.com>

2024-03-01libc: Remove 32bit timespec structures everywhere.Dmitry Chestnykh
With time64 enabled we use statx() system call and the appropriate routines for results conversion. There is no need in `__ts32_struct` anymore. Signed-off-by: Dmitry Chestnykh <dm.chestnykh@gmail.com>

To obtain correct `st_atim`, `st_mtim` and `st_ctim` fields we need to use statx() syscall and then convert the data from the kernel to the regular stat structure. Signed-off-by: Dmitry Chestnykh <dm.chestnykh@gmail.com>

2024-02-25Add support for using time64 on big-endian machines.Dmitry Chestnykh
For BE architectures there is one significant difference in comparison with time64 support for little-endian architectures like ARMv7. The difference is that we strictly need to pass two 64bit values to system calls because Linux Kernel internally uses `struct __kernel_timespec` and similar, which consists of two 64bit fields. For this reason many files have been changed to convert pointers to timespec-family structures (mixed of 64bit and 32bit values) to the pointer of the similar but 64bit-only structures for using as system calls args. This is general prerequisite for any BE architecture. Signed-off-by: Dmitry Chestnykh <dm.chestnykh@gmail.com>
2024-02-25Remove unneeded comparisons.Dmitry Chestnykh

2024-02-25ldso: Remove unneeded semicolons.Dmitry Chestnykh
We use semicolons in the place of `DL_RELOCATE_RELR()` and `DL_DO_RELOCATE_RELR()` 'calling' so the semicolon in the macro definition leads to semicolon duplication after preprocessing. Signed-off-by: Dmitry Chestnykh <dm.chestnykh@gmail.com>
