The pipe2() syscall is available on all Linux platforms since kernel 2.6.27, so use it unconditionally to emulate pipe() and pipe2().Signed-off-by: Helge Deller <del...@gmx.de> diff --git a/linux-user/syscall.c b/linux-user/syscall.c index dbebfa4a8b..b27a6552aa 100644 --- a/linux-user/syscall.c +++ b/linux-user/syscall.c @@ -1586,21 +1586,12 @@ static abi_long do_ppoll(abi_long arg1, abi_long arg2, abi_long arg3, } #endif -static abi_long do_pipe2(int host_pipe[], int flags) -{ -#ifdef CONFIG_PIPE2 - return pipe2(host_pipe, flags); -#else - return -ENOSYS; -#endif -} - static abi_long do_pipe(CPUArchState *cpu_env, abi_ulong pipedes, int flags, int is_pipe2) { int host_pipe[2]; abi_long ret; - ret = is_pipe2 ? do_pipe2(host_pipe, flags) : pipe(host_pipe);
It doesn't apply cleanly: It seems this patch is applied on top of the one you want to replace (is_pipe2 rather than flags). Thanks, Laurent
