[PATCH] xtensa: fix R_XTENSA_TLSDESC_ARG handling in _dl_do_reloc

by Max Filippov

R_XTENSA_TLSDESC_ARG is a true RELA relocation, the addend is in the relocation record itself, not in place.

[PATCH] xtensa: fix _dl_tlsdesc_dynamic

by Max Filippov

There are multiple errors in _dl_tlsdesc_dynamic: - the reference C implementation should return pointer to the thread-local variable, not offset from the thread pointer, because the xtensa ABI expects TLSDESC_FN to return pointer to the TLS variable; - addx8 used for indexing into dtv has its second and third registers in wrong order, the index must be multiplied by 8, not the base; - the same addx8 uses wrong base: instead of dtv it adds the offset to the threadptr; - the return value in the fast path is calculated as td->tlsinfo.ti_offset - __builtin_thread_pointer, not what was intended; - both fast and slow paths should not subtract __builtin_thread_pointer from the result.

[PATCH 0/4] Use varargs for common syscall() implementation

by Stafford Horne

Hello, This is a followup to the ("f764bcffe" or1k: syscall: Pass arguments on the stack) patch which fixes the issue where the definition of syscall() in unistd.h and the common implementation in uclibc-ng don't match. This series allows the implementation to match the definition and then goes on to remove generic implementations used by or1k, nds32 and arc. -Stafford Stafford Horne (4): syscall: Make common implementation match unistd.h or1k: Use new common syscall() implementation nds32: Use new common syscall() implementation arc: Use new common syscall() implementation libc/sysdeps/linux/arc/Makefile.arch | 2 +- libc/sysdeps/linux/arc/syscall.c | 17 ----------------- libc/sysdeps/linux/common/syscall.c | 18 +++++++++++++++++- libc/sysdeps/linux/nds32/Makefile.arch | 4 ++-- libc/sysdeps/linux/nds32/syscall.c | 28 ---------------------------- libc/sysdeps/linux/or1k/Makefile.arch | 2 +- libc/sysdeps/linux/or1k/syscall.c | 32 -------------------------------- 7 files changed, 21 insertions(+), 82 deletions(-) delete mode 100644 libc/sysdeps/linux/arc/syscall.c delete mode 100644 libc/sysdeps/linux/nds32/syscall.c delete mode 100644 libc/sysdeps/linux/or1k/syscall.c -- 2.13.6

[PATCH v2] xtensa: fix strcmp

by Max Filippov

Loops with 'loop forever' annotation inside strcmp are actually meant to loop forever. Falling through the end of the first loop may result in equal strings being compared unequal, e.g.: #include <string.h> int main(void) { char a[4096] __attribute__((aligned(4))); char b[4096] __attribute__((aligned(4))); memset(a, ' ', 258 * 8); memset(b, ' ', 258 * 8); a[255 * 8] = 0; a[256 * 8] = 'a'; b[255 * 8] = 0; b[256 * 8] = 'b'; return !(strcmp(a, b) == 0); } Falling through the end of the second loop may result in unequal strings being compared as equal, e.g.: #include <string.h> int main(void) { char a[4096] __attribute__((aligned(4))); char b[4096] __attribute__((aligned(4))); memset(a, ' ', 514 * 6); memset(b, ' ', 514 * 6); a[514 * 6 + 0] = 'a'; a[514 * 6 + 1] = 0; b[514 * 6 + 0] = 'b'; b[514 * 6 + 1] = 0; return !(strcmp(a, b) != 0); } Use 0 as a loop counter to make 2^32 - 1 iterations which is enough to cover all addressable memory. While at it drop useless nop at the end of the first loop and use a11 for all loop counters.

As it happens, uClibc-0.9.33.2 is OK, Becasue: It's seperated in libpthread.a and libc.a, and the libc.a is the last lib for ld internal-cmd, and malloc will get right cleanup_defer_compat from libpthread.a.
