From: Ларюшкин Алексей (LDemiurg) <ldemiurg@gmail.com.> Newsgroups: email Date: Mon, 17 Dec 2007 14:31:37 +0000 (UTC) Subject: IMQ патч для Linux ядра 2.6.23 Проект LinuxIMQ выпустил последний патч 2007-05-05 и с тех пор в разделе "Patches" ничего свеженького не появлялось. Патч был для ядра 2.6.21 и на более новые ядра он корректно не ставился. А после ручной установки и компиляции, система работала нестабильно внешнее соединения с сервером не держались более 2х минут. Вот доработанный патч для 2.6.23 ядра для нормальной работы. скачать можно тут diff -Nru ./linux-2.6.23-gentoo-r3-orig/drivers/net/imq.c ./linux-2.6.23-gentoo-r3/drivers/net/imq.c --- ./linux-2.6.23-gentoo-r3-orig/drivers/net/imq.c 1970-01-01 03:00:00.000000000 +0300 +++ ./linux-2.6.23-gentoo-r3/drivers/net/imq.c 2007-12-13 17:09:01.000000000 +0200 @@ -0,0 +1,402 @@ +/* + * Pseudo-driver for the intermediate queue device. + * + * This program is free software; you can redistribute it and/or + * modify it under the terms of the GNU General Public License + * as published by the Free Software Foundation; either version + * 2 of the License, or (at your option) any later version. + * + * Authors: Patrick McHardy, <kaber@trash.net.> + * + * The first version was written by Martin Devera, <devik@cdi.cz.> + * + * Credits: Jan Rafaj <imq2t@cedric.vabo.cz.> + * - Update patch to 2.4.21 + * Sebastian Strollo <sstrollo@nortelnetworks.com.> + * - Fix "Dead-loop on netdevice imq"-issue + * Marcel Sebek <sebek64@post.cz.> + * - Update to 2.6.2-rc1 + * + * After some time of inactivity there is a group taking care + * of IMQ again: http://www.linuximq.net + * + * + * 2004/06/30 - New version of IMQ patch to kernels <=2.6.7 including + * the following changes: + * + * - Correction of ipv6 support "+"s issue (Hasso Tepper) + * - Correction of imq_init_devs() issue that resulted in + * kernel OOPS unloading IMQ as module (Norbert Buchmuller) + * - Addition of functionality to choose number of IMQ devices + * during kernel config (Andre Correa) + * - Addition of functionality to choose how IMQ hooks on + * PRE and POSTROUTING (after or before NAT) (Andre Correa) + * - Cosmetic corrections (Norbert Buchmuller) (Andre Correa) + * + * + * 2005/12/16 - IMQ versions between 2.6.7 and 2.6.13 were + * released with almost no problems. 2.6.14-x was released + * with some important changes: nfcache was removed; After + * some weeks of trouble we figured out that some IMQ fields + * in skb were missing in skbuff.c - skb_clone and copy_skb_header. + * These functions are correctly patched by this new patch version. + * + * Thanks for all who helped to figure out all the problems with + * 2.6.14.x: Patrick McHardy, Rune Kock, VeNoMouS, Max CtRiX, + * Kevin Shanahan, Richard Lucassen, Valery Dachev (hopefully + * I didn't forget anybody).
