Jason A. Donenfeld 26c013108c wireguard: netlink: avoid variable-sized memcpy on sockaddr ... Doing a variable-sized memcpy is slower, and the compiler isn't smart enough to turn this into a constant-size assignment. Further, Kees' latest fortified memcpy will actually bark, because the destination pointer is type sockaddr, not explicitly sockaddr_in or sockaddr_in6, so it thinks there's an overflow: memcpy: detected field-spanning write (size 28) of single field "&endpoint.addr" at drivers/net/wireguard/netlink.c:446 (size 16) Fix this by just assigning by using explicit casts for each checked case.
