From mboxrd@z Thu Jan 1 00:00:00 1970 From: Pavel Emelyanov Subject: [PATCH][INET]: Fix accidentally broken inet(6)_hash_connect's port offset calculations. Date: Mon, 04 Feb 2008 11:10:37 +0300 Message-ID: <47A6C87D.7060304@openvz.org> Mime-Version: 1.0 Content-Type: text/plain; charset=ISO-8859-1 Content-Transfer-Encoding: 7bit Cc: Adrian Bunk , Linux Netdev List , devel@openvz.org To: David Miller Return-path: Received: from sacred.ru ([62.205.161.221]:46738 "EHLO sacred.ru" rhost-flags-OK-OK-OK-OK) by vger.kernel.org with ESMTP id S1752768AbYBDIKs (ORCPT ); Mon, 4 Feb 2008 03:10:48 -0500 Sender: netdev-owner@vger.kernel.org List-ID: The port offset calculations depend on the protocol family, but, as Adrian noticed, I broke this logic with the commit 5ee31fc1ecdcbc234c8c56dcacef87c8e09909d8 [INET]: Consolidate inet(6)_hash_connect. Return this logic back, by passing the port offset directly into the consolidated function.
