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>
2024-02-29libc: restore correct definition of semid_ds struct.Dmitry Chestnykh
Previously the common definition of this structure was broken by a mistake. Restore it correctly for all needed architectures and all use cases. Signed-off-by: Dmitry Chestnykh <dm.chestnykh@gmail.com>
2024-02-29Add time64 support for sparc.Dmitry Chestnykh
By some reason sparc ld.so cannot work properly with statx() system call, so fallback to regular stat() family in ld.so. Signed-off-by: Dmitry Chestnykh <dm.chestnykh@gmail.com>

2024-02-28libc: Pass 64bit-only time structures to syscalls.Dmitry Chestnykh
With time64 enabled we need to pass structure which consists of two 64bit fields to clock_gettime64() and clock_nanosleep_time64() syscalls with proper conversion to regular timespec structure after syscall execution. Signed-off-by: Dmitry Chestnykh <dm.chestnykh@gmail.com>

2024-02-27Fix *stat() and *stat64() when the time is beyond year 2038.Dmitry Chestnykh
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>

2024-02-26Refactor `ts32_struct` and `TO_ITS64_P`.Dmitry Chestnykh
- Renamed `ts32_struct` to `__ts32_struct` like `__ts64_struct` and moved its definition to the header. - Removed extra space from TO_ITS64_P() macro. Signed-off-by: Dmitry Chestnykh <dm.chestnykh@gmail.com>
2024-02-25Add time64 support for PowerPC.Dmitry Chestnykh

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
Inside `if` branches the conditions `as->ino == bs->ino` and `as->dev == bs->dev` are always false. Signed-off-by: Dmitry Chestnykh <dm.chestnykh@gmail.com>
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>
2024-02-22xtensa: Add time64 support.Dmitry Chestnykh
- xtensa is the second architecture that supports time64 inside uClibc-ng. - Linux Kernel always uses 32bit time variables inside `stat` structures, so there is a need to use `st_atime`, `st_mtime` and `st_ctime` structures with the same 32bit-wide `tv_sec` and `tv_nsec` variables even if time64 is enabled. Signed-off-by: Dmitry Chestnykh <dm.chestnykh@gmail.com>
2024-02-22Introduce time64 support.Dmitry Chestnykh
This patch introduces *time64 syscalls support for uClibc-ng. Currently the redirection of syscalls to their *time64 analogs is fully supported for 32bit ARM (ARMv5, ARMv6, ARMv7). The main changes that take effect when time64 feature is enabled are: - sizeof(time_t) is 8. - There is a possibility os setting date beyond year 2038. - some syscalls are redirected: clock_adjtime -> clock_adjtime64 clock_getres -> clock_getres_time64 clock_gettime -> clock_gettime64 clock_nanosleep -> clock_nanosleep_time64 clock_settime -> clock_settime64 futex -> futex_time64 mq_timedreceive -> mq_timedreceive_time64 mq_timedsend -> mq_timedsend_time64 ppoll -> ppoll_time64 pselect6 -> pselect6_time64 recvmmsg -> recvmmsg_time64 rt_sigtimedwait -> rt_sigtimedwait_time64 sched_rr_get_interval -> sched_rr_get_interval_time64 semtimedop -> semtimedop_time64 timer_gettime -> timer_gettime64 timer_settime -> timer_settime64 timerfd_gettime -> timerfd_gettime64 timerfd_settime -> timerfd_settime64 utimensat -> utimensat_time64. - settimeofday uses clock_settime (like in glibc/musl). - gettimeofday uses clock_gettime (like in glibc/musl). - nanosleep uses clock_nanosleep (like in glibc/musl). - There are some fixes in data structures used by libc and kernel for correct data handling both with and without enabled time64 support.

While they are not a problem per-se they cause issues with some tooling (such as clang coverage) and are confusing to the reader.
2024-02-20ldso: add null-pointer checkFrank Mehnert
There is a check for (*rpnt == NULL) a few lines above but the "else" case performing an allocation does only exist if SHARED is not defined. If SHARED is defined, the allocation is not performed and it may happen (at least in theory) that *rpnt == NULL when executing (*rpnt)->dyn = tpnt; Add the null-pointer check.

2024-02-18Fix broken compilation of uClibc-ng.Dmitry Chestnykh
During buildroot compilation with latest uClibc I've encoutered linking error due to multiple definition of some symbols from DNS code.
