Redefine FRAMESIZE for such syscalls. This fixes the following testsuite failure: .... tst-mqueue8 FAIL tst-mqueue8 got 1 expected 0 going to cancel mq_receive in-time in-time mq_receive cancellation succeeded going to cancel mq_receive early Didn't expect signal from child: got `Segmentation fault' Signed-off-by: Max Filippov &lt;jcmvbkbc(a)gmail.com&gt; commit 2f478a5d069044cead320c04a2ad9998a2651551 Author: Max Filippov &lt;jcmvbkbc(a)gmail.com&gt; Date: Mon Jun 22 04:10:54 2015 +0300 xtensa: add ret_ERRVAL definition ret_ERRVAL is used by mq_timedsend and mq_timedreceive, it needs to be defined to retw, otherwise error return from those functions segfaults. This fixes the following testsuite failures: .... tst-mqueue1 FAIL tst-mqueue1 got 1 expected 0 Didn't expect signal from child: got `Segmentation fault' .... tst-mqueue2 FAIL tst-mqueue2 got 1 expected 0 Didn't expect signal from child: got `Segmentation fault' .... tst-mqueue3 FAIL tst-mqueue3 got 1 expected 0 Didn't expect signal from child: got `Segmentation fault' .... tst-mqueue4 FAIL tst-mqueue4 got 1 expected 0 Didn't expect signal from child: got `Segmentation fault' .... tst-mqueue5 FAIL tst-mqueue5 got 1 expected 0 Didn't expect signal from child: got `Segmentation fault' .... tst-mqueue6 FAIL tst-mqueue6 got 1 expected 0 Didn't expect signal from child: got `Segmentation fault' Signed-off-by: Max Filippov &lt;jcmvbkbc(a)gmail.com&gt; ----------------------------------------------------------------------- Summary of changes: libc/sysdeps/linux/xtensa/sysdep.h | 5 +++++ .../nptl/sysdeps/unix/sysv/linux/xtensa/sysdep-cancel.h | 10 +++++++++- 2 files changed, 14 insertions(+), 1 deletion(-) diff --git a/libc/sysdeps/linux/xtensa/sysdep.h b/libc/sysdeps/linux/xtensa/sysdep.h index cab4a2f..4873a41 100644 --- a/libc/sysdeps/linux/xtensa/sysdep.h +++ b/libc/sysdeps/linux/xtensa/sysdep.h @@ -72,7 +72,9 @@ #define JUMPTARGET(name) name #endif +#ifndef FRAMESIZE #define FRAMESIZE 16 +#endif #define CALL_MCOUNT /* Do nothing. */ @@ -130,6 +132,9 @@ #define PSEUDO_END_ERRVAL(name) \ END (name) +#undef ret_ERRVAL +#define ret_ERRVAL retw + #if defined _LIBC_REENTRANT # if defined USE___THREAD # ifndef NOT_IN_libc diff --git a/libpthread/nptl/sysdeps/unix/sysv/linux/xtensa/sysdep-cancel.h b/libpthread/nptl/sysdeps/unix/sysv/linux/xtensa/sysdep-cancel.h index 6bb2aeb..f82957d 100644 --- a/libpthread/nptl/sysdeps/unix/sysv/linux/xtensa/sysdep-cancel.h +++ b/libpthread/nptl/sysdeps/unix/sysv/linux/xtensa/sysdep-cancel.h @@ -24,7 +24,15 @@ #endif #if !defined NOT_IN_libc || defined IS_IN_libpthread || defined IS_IN_librt -// FIXME: ENTRY includes an entry instruction, here we'd want entry sp, 48! + +/* CENABLE/CDISABLE in PSEUDO below use call8, stack frame size must be + * at least 32. + */ +#if FRAMESIZE < 32 +#undef FRAMESIZE +#define FRAMESIZE 32 +#endif + # undef PSEUDO # define PSEUDO(name, syscall_name, args) \ .text; \ hooks/post-receive -- uClibc-ng - small C library for embedded systems
