Jakub Sitnicki d5bee7374b net/tls: Annotate access to sk_prot with READ_ONCE/WRITE_ONCE ... sockmap performs lockless writes to sk->sk_prot on the following paths: tcp_bpf_{recvmsg|sendmsg} / sock_map_unref sk_psock_put sk_psock_drop sk_psock_restore_proto WRITE_ONCE(sk->sk_prot, proto) To prevent load/store tearing [1], and to make tooling aware of intentional shared access [2], we need to annotate other sites that access sk_prot with READ_ONCE/WRITE_ONCE macros. Change done with Coccinelle with following semantic patch: @@ expression E; identifier I; struct sock *sk; identifier sk_prot =~ "^sk_prot$"; @@ ( E = -sk->sk_prot +READ_ONCE(sk->sk_prot) | -sk->sk_prot = E +WRITE_ONCE(sk->sk_prot, E) | -sk->sk_prot +READ_ONCE(sk->sk_prot) ->I ) Signed-off-by: Jakub Sitnicki <jakub@cloudflare.com> Signed-off-by: David S.
