2024-09-08Revert "mips64: time64 for n32 ABI breaks a lot of tests, disable it for now"Dmitry Chestnykh

2024-09-08mips64n32, time64: Select correct _dl_fstat implDmitry Chestnykh
With time64 enabled we have to use statx() instead of stat() or fstat() If the _dl_fstat implementation isn't selected correctly we can have multiple errors inside dynamic linker during startup of the system and of the almost every process Add sparc exclusion like in other places inside this header Signed-off-by: Dmitry Chestnykh <dm.chestnykh@gmail.com>

2024-08-13getrandom: remove __USE_GNU / add GRND_INSECUREWaldemar Brodkorb
Neither glibc nor musl use __GNU macro to hide getrandom. While there sync with glibc and add GRND_INSECURE flag.

2024-07-30iconv: prevent compiler warning during initialization with jis0208Frank Mehnert
The data in jis0208.h initializes a two-dimensional array, so insert the missing braces to prevent a compiler warning about missing braces around initializer. Signed-off-by: Marcus Haehnel <marcus.haehnel@kernkonzept.com>
2024-07-30iconv: fix parameter type of utf8seq_is_{overlong,surrogate,illegal}Frank Mehnert
Use `unsigned char *s` rather than `char *s`. First, this fixes compiler warnings when these functions are called from utf8dec_wchar() passing the `in` pointer of type `unsigned char *`. Second, these functions are always called with characters >= 0x80 so the sign bit is set. Shifting right a negative signed value will insert `1` from the left side, so `foo >> 1` where foo is negative will always have the sign bit set. So at least "case 2" would never return true. There is a similar problem with tests like (*(s+1) >= 0xA0) && (*(s+1) <= 0xBF) This condition is always false with `char *s`. Signed-off-by: Marcus Haehnel <marcus.haehnel@kernkonzept.com>
2024-07-30ldso.c: use 'unsigned int' as loop variable typeFrank Mehnert
As the condition for terminating the loop compares the loop variable against an ElfW() variable which is, depending on the platform, either uint32_t or uint64_t, use 'unsigned int' rather than 'int' for the loop variable to prevent corresponding compiler warnings. Note that it would not make sense to use 'unsigned long' because the number of program headers will never exceed 32-bit. Signed-off-by: Marcus Haehnel <marcus.haehnel@kernkonzept.com>
2024-07-30iconv: explicitly state operator precedenceFrank Mehnert
gcc suggests to set parentheses around '-'/'+' inside '<<' if the corresponding warnings are enabled. Make the compiler happy and make the code easier to understand for developers. Signed-off-by: Marcus Haehnel <marcus.haehnel@kernkonzept.com>
2024-07-30iconv: explicit cast to `unsigned char*`Frank Mehnert
Perform an explicit cast to prevent the corresponding compiler warning. Signed-off-by: Marcus Haehnel <marcus.haehnel@kernkonzept.com>
2024-07-30libdl: properly cast parameters for %p format string specifierFrank Mehnert
The "%p" format specifier requires a void pointer. Cast parameters of type ElfW(Addr) to 'void *'. This fixes warnings if _dl_if_debug_print() performs parameter type checking. Signed-off-by: Marcus Haehnel <marcus.haehnel@kernkonzept.com>
2024-07-30Group conditions after `&&`Dmitry Chestnykh
If the conditions are not grouped we can reach this block even if `__NR_stat` is not defined. `defined __NR_stat && ((!defined(__UCLIBC_USE_TIME64__) || defined(__sparc__))` gives us false but `LINUX_VERSION_CODE <= KERNEL_VERSION(5,1,0))` may give us true. So if linux headers version is below 5.1.0 and __NR_stat is not defined we can have compilation error Signed-off-by: Dmitry Chestnykh <dm.chestnykh@gmail.com>
2024-07-27bits/stat.h: Declare st_mtim if defined(__USE_XOPEN2K8), everywhereJ. Neuschäfer
While building software that sets _POSIX_C_SOURCE=200809L and uses stat.st_mtim for ARM, it was noticed that st_mtim was not defined. This seems to be because common/bits/stat.h was picked up, which does not take __USE_XOPEN2K8 as a reason to enable st_mtim and related fields. This appears to be an oversight, and porting the check from common-generic/bits/stat.h to other architectures does indeed fix the build issue. This patch is based on commit 50bd6d06e ("Fix memory corruption due to struct stat field"). Signed-off-by: J. Neuschäfer <j.neuschaefer@gmx.net>

2024-07-21Fix compilation with 4.x kernel headersDmitry Chestnykh
- Fallback to __NR_stat syscall in ld.so if we use 4.x kernel headers. 4.x kernel doesn't support 64-bit time so we can use old syscall - Add preprocessor conditions to have fstat64 and fstatat64 in libc with old kernel headers Signed-off-by: Dmitry Chestnykh <dm.chestnykh@gmail.com>
2024-07-19arm: Replace deprecated asm instructions for ARMv8 AArch32Valentin Gehrke
ARMv8 has particular restrictions which coprocessor can be used and as such these instructions, which were likely used for backwards compatibility purposes, cannot be used on ARMv8. We solve this by checking for ARMv8 and then using the corresponding mnemonics which were placed in comments alongside the instructions causing issues. Fixes the following errors: .../setjmp.S:59:6: error: invalid operand for instruction stc p11, cr8, [r12], #68 ^ .../setjmp.S:62:6: error: invalid operand for instruction mrc p10, 7, r2, cr1, cr0, 0 ^ .../__longjmp.S:69:6: error: invalid operand for instruction ldc p11, cr8, [r12], #68 ^ .../__longjmp.S:73:6: error: invalid operand for instruction mcr p10, 7, r1, cr1, cr0, 0 ^ Signed-off-by: Marcus Haehnel <marcus.haehnel@kernkonzept.com>

For architectures without ucontext implementation it is possible to use libucontext with this small adaptation.
2024-07-09Clang support for gnu_inline attributeWaldemar Brodkorb
Clang also supports the gnu_inline attribute and the __GNUC_STDC_INLINE__ macro (C99 semantics). However, it reports as GCC 4.2 compatible (__GNUC_MINOR__ / __GNUC__) and thus the current defines do not think it can support this. Add clang as an alternative for this support. Documentation shows that this attribute is supported since at least Clang 8. Signed-off-by: Marcus Haehnel <marcus.haehnel@kernkonzept.com>
2024-07-09buildsys: allow building with gcc-14Marcus Haehnel
GCC-14 requires all functions to have an explicit return type. An implicit return type is no longer supported. main() in the ncurses link check was declared without return type. Add it to make this work on GCC-14. See also: https://gcc.gnu.org/gcc-14/porting_to.html Signed-off-by: Marcus Haehnel <marcus.haehnel@kernkonzept.com>

2024-07-09c++: Remove deprecated dynamic exception specificationSven Linker
Dynamic exception specification using `throw()` is deprecated since C++11 and removed in C++17. This change replaces `throw()` with `noexcept` when compiling for newer standards. Co-authored-by: Sven Linker <sven.linker@kernkonzept.com> Signed-off-by: Marcus Haehnel <marcus.haehnel@kernkonzept.com>
2024-07-09stdlib: increase number of static atexit handlers to 32Yann Le Du
The existing limit of 20 was found to be insufficient when moving from gcc 8 to gcc 9. At the time a test ran already 16 handlers had been installed leaving only minimal room for application installed handlers. Musl uses 32, as does newlib. Further, the ISO C standard for C99 specifies that: The implementation shall support the registration of at least 32 functions.

2024-07-09libm: Fix float conversion compiler warningMarcus Haehnel

2024-07-09uclibc: Fix double promotion warningMarcus Haehnel

2024-07-09ldso/dl-vdso: avoid compiler warning if configured without vdsoMarcus Haehnel
The parameters are not used in the function variant without vdso support, so tell this to the compiler to avoid a warning. Also fix the indentation to be in-line with other functions in the file. Signed-off-by: Marcus Haehnel <marcus.haehnel@kernkonzept.com>

2024-06-15libc: cast free() argument to void * in wchar.cYuriy Kolerov
iconv_close() accepts iconv_t type (which is void *) and passes it to free() which accepts void *. However, GCC 14 raises a -Wint-conversion warning if it is not casted to void * because GCC cannot unwind typedef of iconv_t. Signed-off-by: Yuriy Kolerov <ykolerov@synopsys.com>
