From mboxrd@z Thu Jan 1 00:00:00 1970 From: Jay Rouman Subject: LInux kernel 3.0 sit creation bug report Date: Sat, 23 Jul 2011 12:27:20 -0400 (EDT) Message-ID: Reply-To: jsr@dex.edzone.net Mime-Version: 1.0 Content-Type: text/plain; charset="US-ASCII" Content-Transfer-Encoding: 7bit To: netdev@vger.kernel.org, davem@davemloft.net Return-path: Received: from dex.edzone.net ([207.74.88.2]:33790 "EHLO dex.edzone.net" rhost-flags-OK-OK-OK-OK) by vger.kernel.org with ESMTP id S1753071Ab1GWQ4r (ORCPT ); Sat, 23 Jul 2011 12:56:47 -0400 Sender: netdev-owner@vger.kernel.org List-ID: Kernel 3.0 (release version) Summary: sit tunnel creation fails with "No buffer space available" Example: icebox:/home/u/jsr(3)# /sbin/ip tunnel add sit0 mode sit local 216.111.203.89 remote 209.51.18.1 ttl 255 add tunnel sit0 failed: No buffer space available icebox:/home/u/jsr(8)# /sbin/ifconfig sit0 inet6 tunnel ::209.51.18.1 SIOCSIFDSTADDR: No buffer space available Notes: Oddly, the ifconfig example creates a working sit0. The "ip" example does not. The problem existed in rc1 but unfortunately I did not test sit creation then. This was discovered when I upgraded a machine with an HE tunnel to the 3.0 kernel. I am happy to do further testing or provide whatever additional info I can.
