From ce7ae180620a2fbf66232c3556678fbf4f136a5c Mon Sep 17 00:00:00 2001 From: Sergei Trofimovich Date: Wed, 15 Apr 2020 19:28:42 +0100 Subject: [PATCH] linux-user/syscall.c: add target-to-host mapping for epoll_create1() MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Noticed by Barnabás Virágh as a python-3.7 failue on qemu-alpha. The bug shows up on alpha as it's one of the targets where EPOLL_CLOEXEC differs from other targets: sysdeps/unix/sysv/linux/alpha/bits/epoll.h: EPOLL_CLOEXEC = 01000000 sysdeps/unix/sysv/linux/bits/epoll.h: EPOLL_CLOEXEC = 02000000 Bug: https://bugs.gentoo.org/717548 Reported-by: Barnabás Virágh Signed-off-by: Sergei Trofimovich --- linux-user/syscall.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/linux-user/syscall.c b/linux-user/syscall.c index 674f70e70a..05f03919ff 100644 --- a/linux-user/syscall.c +++ b/linux-user/syscall.c @@ -12012,7 +12012,7 @@ static abi_long do_syscall1(void *cpu_env, int num, abi_long arg1, #endif #if defined(TARGET_NR_epoll_create1) && defined(CONFIG_EPOLL_CREATE1) case TARGET_NR_epoll_create1: - return get_errno(epoll_create1(arg1)); + return get_errno(epoll_create1(target_to_host_bitmask(arg1, fcntl_flags_tbl))); #endif #if defined(TARGET_NR_epoll_ctl) case TARGET_NR_epoll_ctl: -- 2.26.1
