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 --- net/compat.c | 25 ------------------------- 1 file changed, 25 deletions(-) (limited to 'net/compat.c') diff --git a/net/compat.c b/net/compat.c index 69fc6d1e4e6e..032114de4fec 100644 --- a/net/compat.c +++ b/net/compat.c @@ -448,34 +448,9 @@ COMPAT_SYSCALL_DEFINE5(getsockopt, int, fd, int, level, int, optname, return __compat_sys_getsockopt(fd, level, optname, optval, optlen); } -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; - #define __COMPAT_GF0_SIZE (sizeof(struct compat_group_filter) - \ sizeof(struct __kernel_sockaddr_storage)) - int compat_mc_setsockopt(struct sock *sock, int level, int optname, char __user *optval, unsigned int optlen, int (*setsockopt)(struct sock *, int, int, char __user *, unsigned int)) -- cgit
