From: Ben Hutchings Date: Wed, 6 Feb 2019 11:35:06 +0300 Subject: sparc64 timeval.tv_usec is int On sparc (only) Linux defines timeval::tv_usec with type int, not long. However qemu-user's definition of struct target_timeval uses abi_long unconditionally. This results in the syscall translation layer effectively multiplying tv_usec by 2**32. All sparc syscalls passing non-zero values for this field fail with -EINVAL. Laurent Vivier : According to the kernel definition, I think it should be: See arch/sparc/include/uapi/asm/posix_types.h typedef int __kernel_suseconds_t; .. --- linux-user/syscall_defs.h | 4 ++++ 1 file changed, 4 insertions(+) diff --git a/linux-user/syscall_defs.h b/linux-user/syscall_defs.h index 99bbce083c..106eafe7fc 100644 --- a/linux-user/syscall_defs.h +++ b/linux-user/syscall_defs.h @@ -210,7 +210,11 @@ struct target_linger { struct target_timeval { abi_long tv_sec; +#if defined(TARGET_SPARC64) && !defined(TARGET_ABI32) + abi_int tv_usec; +#else abi_long tv_usec; +#endif }; struct target_timespec { -- 2.11.0
