Kuniyuki IwashimaandJakub Kicinski b748765019 net: Annotate sk->sk_write_space() for UDP SOCKMAP. ...

UDP TX skb->destructor() is sock_wfree(), and UDP holds lock_sock()
only for UDP_CORK / MSG_MORE sendmsg().

Otherwise, sk->sk_write_space() may be read locklessly while SOCKMAP
rewrites sk->sk_write_space().

Let's use WRITE_ONCE() and READ_ONCE() for sk->sk_write_space().

Note that the write side is annotated by commit 2ef2b20cf4
("net: annotate data-races around sk->sk_{data_ready,write_space}").

Fixes: 7b98cd42b0 ("bpf: sockmap: Add UDP support")
