From 7030c0cd98de9e6c42e69be314204727ae335912 Mon Sep 17 00:00:00 2001 From: Khem Raj Date: Thu, 10 Oct 2024 22:40:32 -0700 Subject: [PATCH] sched_attr: Do not define for glibc >= 2.41 glibc 2.41+ has added [1] definitions for sched_setattr and sched_getattr functions and struct sched_attr. Therefore, it needs to be checked for here as well before defining sched_attr Define sched_attr conditionally on SCHED_ATTR_SIZE_VER0 Fixes builds with glibc/trunk [1] https://sourceware.org/git/?p=glibc.git;a=commitdiff;h=21571ca0d70302909cf72707b2a7736cf12190a0;hp=298bc488fdc047da37482f4003023cb9adef78f8 Upstream-Status: Submitted [https://patchwork.ozlabs.org/project/qemu-devel/patch/20241011193140.1047648-1-raj.khem@gmail.com/] Signed-off-by: Khem Raj Cc: Laurent Vivier Cc: Paolo Bonzini --- linux-user/syscall.c | 4 +++- 1 file changed, 3 insertions(+), 1 deletion(-) diff --git a/linux-user/syscall.c b/linux-user/syscall.c index 27aa59594..b2c45b4c4 100644 --- a/linux-user/syscall.c +++ b/linux-user/syscall.c @@ -361,7 +361,8 @@ _syscall3(int, sys_sched_getaffinity, pid_t, pid, unsigned int, len, #define __NR_sys_sched_setaffinity __NR_sched_setaffinity _syscall3(int, sys_sched_setaffinity, pid_t, pid, unsigned int, len, unsigned long *, user_mask_ptr); -/* sched_attr is not defined in glibc */ +/* sched_attr is not defined in glibc < 2.41 */ +#ifndef SCHED_ATTR_SIZE_VER0 struct sched_attr { uint32_t size; uint32_t sched_policy; @@ -374,6 +375,7 @@ struct sched_attr { uint32_t sched_util_min; uint32_t sched_util_max; }; +#endif #define __NR_sys_sched_getattr __NR_sched_getattr _syscall4(int, sys_sched_getattr, pid_t, pid, struct sched_attr *, attr, unsigned int, size, unsigned int, flags);
