[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 … [View More]

[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.

[PATCH] bits/stat.h: Declare st_mtim if defined(__USE_XOPEN2K8), everywhere
by J. Neuschäfer 30 Jul '24

30 Jul '24

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 … [View More]struct stat field"). Signed-off-by: J.

[PATCH] iconv: fix parameter type of utf8seq_is_{overlong,surrogate,illegal}
by Marcus Haehnel 29 Jul '24

29 Jul '24

From: Frank Mehnert <frank.mehnert(a)kernkonzept.com> 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 … [View More]

[PATCH] ldso.c: use 'unsigned int' as loop variable type
by Marcus Haehnel 29 Jul '24

29 Jul '24

From: Frank Mehnert <frank.mehnert(a)kernkonzept.com> 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(a)… [View More]
