vsock/uapi: fix linux/vm_sockets.h userspace compilation errors
[ Upstream commit 22bbc1dcd0d6785fb390c41f0dd5b5e218d23bdd ]
If a userspace application just include <linux/vm_sockets.h> will fail
to build with the following errors:
/usr/include/linux/vm_sockets.h:182:39: error: invalid application of ‘sizeof’ to incomplete type ‘struct sockaddr’
182 | unsigned char svm_zero[sizeof(struct sockaddr) -
| ^~~~~~
/usr/include/linux/vm_sockets.h:183:39: error: ‘sa_family_t’ undeclared here (not in a function)
183 | sizeof(sa_family_t) -
|
Include <sys/socket.h> for userspace (guarded by ifndef __KERNEL__)
where `struct sockaddr` and `sa_family_t` are defined.
We already do something similar in <linux/mptcp.h> and <linux/if.h>.
