From 63287de66df11308d239483415d67fe94079f47b Mon Sep 17 00:00:00 2001 From: Al Viro Date: Sat, 9 May 2020 20:58:17 -0400 Subject: lift compat definitions of mcast [sg]etsockopt requests into net/compat.h We want to get rid of compat_mc_[sg]etsockopt() and to have that stuff handled without compat_alloc_user_space(), extra copying through userland, etc. To do that we'll need ipv4 and ipv6 instances of ->compat_[sg]etsockopt() to manipulate the 32bit variants of mcast requests, so we need to move the definitions of those out of net/compat.c and into a public header. This patch just does a mechanical move to include/net/compat.h Signed-off-by: Al Viro --- include/net/compat.h | 24 ++++++++++++++++++++++++ 1 file changed, 24 insertions(+) (limited to 'include/net/compat.h') diff --git a/include/net/compat.h b/include/net/compat.h index 2b5e1f7ba153..69a8cd29c0ae 100644 --- a/include/net/compat.h +++ b/include/net/compat.h @@ -74,4 +74,28 @@ int compat_mc_getsockopt(struct sock *, int, int, char __user *, int __user *, int (*)(struct sock *, int, int, char __user *, int __user *)); +struct compat_group_req { + __u32 gr_interface; + struct __kernel_sockaddr_storage gr_group + __aligned(4); +} __packed; + +struct compat_group_source_req { + __u32 gsr_interface; + struct __kernel_sockaddr_storage gsr_group + __aligned(4); + struct __kernel_sockaddr_storage gsr_source + __aligned(4); +} __packed; + +struct compat_group_filter { + __u32 gf_interface; + struct __kernel_sockaddr_storage gf_group + __aligned(4); + __u32 gf_fmode; + __u32 gf_numsrc; + struct __kernel_sockaddr_storage gf_slist[1] + __aligned(4); +} __packed; + #endif /* NET_COMPAT_H */ -- cgit v1.2.3
