Hi uClibc-ng hackers, I released 1.0.50 today. See his git shortlog for changes: Dmitry Chestnykh (2): Fix compilation with 4.x kernel headers Group conditions after `&&` Frank Mehnert (6): libdl: properly cast parameters for %p format string specifier iconv: explicit cast to `unsigned char*` iconv: explicitly state operator precedence ldso.c: use 'unsigned int' as loop variable type iconv: fix parameter type of utf8seq_is_{overlong,surrogate,illegal} iconv: prevent compiler warning during initialization with jis0208 J. Neuschäfer (1): bits/stat.h: Declare st_mtim if defined(__USE_XOPEN2K8), everywhere Marcus Haehnel (5): ldso/dl-vdso: avoid compiler warning if configured without vdso uclibc: Fix double promotion warning libm: Fix float conversion compiler warning features.h: add clang prerequisite macro buildsys: allow building with gcc-14 Sven Linker (1): c++: Remove deprecated dynamic exception specification Valentin Gehrke (1): arm: Replace deprecated asm instructions for ARMv8 AArch32 Waldemar Brodkorb (9): Clang support for gnu_inline attribute allow to use <sys/ucontext.h> add SEEK_DATA/SEEK_HOLE lseek: allow SEEK_DATA/SEEK_HOLE to be used bits/stat.h: Declare st_mtim if defined(__USE_XOPEN2K8), add missing riscv: remove incomplete context implementation, use libucontext add memfd_create syscall wrapper getrandom: remove __USE_GNU / add GRND_INSECURE bump version for 1.0.50 release Yann Le Du (1): stdlib: increase number of static atexit handlers to 32 Happy Updating! Sunshine, Waldemar Brodkorb

[PATCH] [ldso] Group conditions after `&&`
by Dmitry Chestnykh 01 Aug '24

01 Aug '24

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(a)gmail.com> --- ldso/include/dl-syscall.h | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/ldso/include/dl-syscall.h b/ldso/include/dl-syscall.h index 9ec0eac60..180d03012 100644 --- a/ldso/include/dl-syscall.h +++ b/ldso/include/dl-syscall.h @@ -141,7 +141,7 @@ static __always_inline int _dl_stat(const char *file_name, { return _dl_newfstatat(AT_FDCWD, file_name, buf, 0); } -#elif defined __NR_stat && (!defined(__UCLIBC_USE_TIME64__) || defined(__sparc__)) || (LINUX_VERSION_CODE <= KERNEL_VERSION(5,1,0)) +#elif defined __NR_stat && (!defined(__UCLIBC_USE_TIME64__) || defined(__sparc__) || (LINUX_VERSION_CODE <= KERNEL_VERSION(5,1,0))) # define __NR__dl_stat __NR_stat static __always_inline _syscall2(int, _dl_stat, const char *, file_name, struct stat *, buf) -- 2.45.2

[PATCH] libdl: properly cast parameters for %p format string specifier
by Marcus Haehnel 01 Aug '24

01 Aug '24

From: Frank Mehnert <frank.mehnert(a)kernkonzept.com> 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.
