From mboxrd@z Thu Jan 1 00:00:00 1970 From: Daniel Borkmann Subject: [PATCH net-next v2 0/5] BPF/random32 updates Date: Thu, 8 Oct 2015 01:20:34 +0200 Message-ID: Cc: hannes@stressinduktion.org, ast@plumgrid.com, netdev@vger.kernel.org, Daniel Borkmann To: davem@davemloft.net Return-path: Received: from www62.your-server.de ([213.133.104.62]:37253 "EHLO www62.your-server.de" rhost-flags-OK-OK-OK-OK) by vger.kernel.org with ESMTP id S1751241AbbJGXUr (ORCPT ); Wed, 7 Oct 2015 19:20:47 -0400 Sender: netdev-owner@vger.kernel.org List-ID: BPF update to split the prandom state apart, and to move the *once helpers to the core. For details, please see individual patches. Given the changes and since it's in the tree for quite some time, net-next is a better choice in our opinion. v1 -> v2: - Make DO_ONCE() type-safe, remove the kvec helper. Credits go to Alexei Starovoitov for the __VA_ARGS__ hint, thanks! - Add a comment to the DO_ONCE() helper as suggested by Alexei. - Rework prandom_init_once() helper to the new API. - Keep Alexei's Acked-by on the last patch. Thanks!
