From 15a7dea750e0162f273c6e61a94f96944b75b31e Mon Sep 17 00:00:00 2001 From: Jakub Kicinski Date: Fri, 30 Aug 2019 12:25:47 +0200 Subject: net/tls: use RCU protection on icsk->icsk_ulp_data We need to make sure context does not get freed while diag code is interrogating it. Free struct tls_context with kfree_rcu(). We add the __rcu annotation directly in icsk, and cast it away in the datapath accessor. Presumably all ULPs will do a similar thing.
