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>

2024-02-22Introduce 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.

2023-11-09libpthread/nptl: make default stack size configurableBen Wolsieffer
Threads currently have 2-4 MiB stacks by default (depending on the platform). This is fine on MMU platforms, where this stack space is not actually allocated until it is used, but tends to waste a large amount of memory on no-MMU platforms. This patch adds a PTHREADS_STACK_DEFAULT_SIZE Kconfig option that allows the user to override the default stack size at build time. This allows the user to select a reasonable default stack size for the software that runs on their system, and avoids the need to patch every package to add calls to pthread_attr_setstacksize(). An alternative to this patch would be to change the hardcoded default stack size on no-MMU platforms, but it is difficult to choose an appropriate value because the minimum required stack depends on the software in use. This would also be a breaking change. Signed-off-by: Ben Wolsieffer <ben.wolsieffer@hefring.com>
2023-10-28Fix -Warray-parameter warning for __sigsetjmpPavel Kozlov
Fix the [-Warray-parameter=] warning for __sigsetjmp generated by GCC 11 and later GCC versions: | | warning: argument 1 of type 'struct __jmp_buf_tag *' declared as a pointer [-Warray-parameter=] | extern int __sigsetjmp (struct __jmp_buf_tag *__env, int __savemask) __THROWNL; | ... | note: previously declared as an array 'struct __jmp_buf_tag[1]' | extern int __sigsetjmp (struct __jmp_buf_tag __env[1], int __savemask) | Use the same fix as in glibc. The fix is to move the struct __jmp_buf_tag definition to a separate bits/ header so it can be included in pthread.h, to allow to use an array (as in setjmp.h) rather than a pointer in the declaration.

2022-09-21static pie: fix building static PDEMax Filippov
When uclibc is built with static PIE support the _dl_load_base variable shared between the libc-tls.c and reloc_static_pie.c creates the dependency that requires linking reloc_static_pie.o into static position-dependent executables resulting in the following build errors: gcc -static test.c -o test ...ld: ...usr/lib/libc.a(reloc_static_pie.os):(.text+0x0): undefined reference to `_DYNAMIC' Move _dl_load_base definition to libc-tls.c to resolve this dependency and fix static PDE build.

2022-09-07nptl: use mmap to allocate initial TLS data for static PIE on noMMUMax Filippov
Static PIE ELFs may be loaded on noMMU linux platforms with FDPIC support, but they don't have adjustable brk, and thus cannot allocate memory for the TLS. Use mmap instead of sbrk to allocate initial TLS memory when building with static PIE support for noMMU. Signed-off-by: Max Filippov <jcmvbkbc@gmail.com>
2022-07-26Added support for creation of Static Position-Independent Executables (PIE) ↵linted
on i386, x86_64, and arm. This patch adds the generation of rcrt1.o which is used by gcc when compiling with the --static-pie flag. rcrt1.o differs from crt1.o and Scrt1.o in that it the executable has a dynamic section but no relocations have been performed prior to _start being called. crt1.o assumes there to be no dynamic relocations, and Scrt1.o has all relocations performed prior to execution by lsdo. The new reloc_static_pie function handles parsing the dynamic section, and performing the relocations in a architecture agnostic method. It also sets _dl_load_base which is used when initalizing TLS to ensure loading from the proper location. This allows for easier porting of static-pie support to additional architectures as only modifications to crt1.S to find the load address are required.

2019-10-30Make __syscall_error return long, as expected by syscall() callersCarlos Santos
The return type of syscall() is long so __syscall_error, which is jumped to by syscall handlers to stash an error number into errno, must return long too otherwhise it returs 4294967295L instead of -1L. For example, syscall for x86_64 is defined in libc/sysdeps/linux/x86_64/syscall.S as syscall: movq %rdi, %rax /* Syscall number -> rax. */ movq %rsi, %rdi /* shift arg1 - arg5. */ movq %rdx, %rsi movq %rcx, %rdx movq %r8, %r10 movq %r9, %r8 movq 8(%rsp),%r9 /* arg6 is on the stack. */ syscall /* Do the system call. */ cmpq $-4095, %rax /* Check %rax for error. */ jae __syscall_error /* Branch forward if it failed. */ ret /* Return to caller. */ In libc/sysdeps/linux/x86_64/__syscall_error.c, __syscall_error is defined as int __syscall_error(void) attribute_hidden; int __syscall_error(void) { register int err_no __asm__ ("%rcx"); __asm__ ("mov %rax, %rcx\n\t" "neg %rcx"); __set_errno(err_no); return -1; } So __syscall_error returns -1 as a 32-bit int in a 64-bit register, %rax (0x00000000ffffffff, whose decimal value is decimal 4294967295) and a test like this always returns false: if (syscall(number, ...) == -1) foo(); Fix the error by making __syscall_error return a long, like syscall(). The problem can be circumvented by the caller by coercing the returned value to int before comparing it to -1: if ((int) syscall(number, ...) == -1) foo(); The same problem probably occurs on other 64-bit systems but so far only x86_64 was tested, so this change must be considered experimental.
