Hi all, The patch below does four trivial changes and one big change Trivial changes, these are all in br_netfilter.c: - check ar_pln==4 when giving bridged ARP packets to arptables - delete unnecessary if in br_nf_local_in - add more logging for the "Argh" message - add some brag-comments in the file head comment Big change: let {ip,arp}tables see VLAN tagged {I,AR}P packets. This

Hi, after I saw that my machine was having problems to forward more than 200 Mbit/s, I decided to profile the kernel and find out the hotspots. This is what I found: [...] 1028 bridge.ko __br_forward 1033 bridge.ko br_nf_forward_finish 1074 bridge.ko ip_sabotage_in 1119 ebtable_filter.ko ebt_hook 1177 sky2.ko

Hi, I met a problem when using bridge with netfilter. The kernel version 2.4.20, and the patch is bridge-nf-0.0.10-against-2.4.20.diff. Our firewall configuration is as follows, eth3,eth4,eth5,eth6 configured as a bridge with an IP address 10.0.0.1. The local net connect to the internet via the gateway 10.0.0.1 and SNAT is applied on the firewall. It worked but sometimes there are some

I recently encountered this in the logs of a new Debian Xen Dom0, and having now spent the better part of a day researching and testing, I've come to the conclusion that this is not a bug in xen-utils-common or even iptables; it's merely the consequence of structural changes to the core netfilter code starting in the 2.6.20 kernel. This is rather long, but the issue is complicated. Please

Looks like the GSO is involved? I got this while running Dom0 only (no guests), with a BOINC/Rosetta@home application running on all 4 cores. changeset: 10649:8e55c5c11475 Build: x86_32p (pae). ------------[ cut here ]------------ kernel BUG at net/core/dev.c:1133! invalid opcode: 0000 [#1] SMP CPU: 0 EIP: 0061:[<c04dceb0>] Not tainted VLI EFLAGS: 00210297 (2.6.16.13-xen

hi,all each port of bridge, has its packets process function called br_handle_frame. i want to know before this function called who and how it get the packets? if it is a real physical ethernet, it must be its driver, but for virtual ethernet , what is the driver? thanks -------------- next part -------------- An HTML attachment was scrubbed...

Hi, One of my servers has had its dom0 "oops" over and over twice in the last week. Unfortunately this is newly deployed so I have no idea if it is down to Xen or not. xen_changeset : Mon Dec 12 18:47:47 2005 +0100 8270:4ad23e798798 dom0 kernel is a vanilla 2.6.12 with Ralph''s .6+xen kernel patch applied. x86_32 sarge packages were used. The .config is

(please keep me on Cc when replying) I have a server running Xen that regularly spews the following. The box seems to survive fine regardless - just thought I''d let everyone know.

Hello, i need to write a little personal patch in the bridge code. For this patch, i need to know the original src and dst mac addresses of the packet incoming to the bridge. As i work on a brouter (some packets are bridged, some are routed based on ebtable rules), packets that are routed have their mac addresses modified by the IP stack). I put a software probe in br_input.c::br_handle_frame( ),

Hi there, I am new to ebtables code and looking for some help related to locking and atomicity. I am using Xen 3.0.4 in bridge mode and interested in looking into the packets intercepted by dom0 ebtables code, extract some information, pass this information to userspace, wait for userspace response and then pass the result back to ebtable code. Everything seemed to be working fine until i

Hi All, For my issue, first thanks to ALL, I have some idea of it. Also Thank Peter for his kind remind, I would become one good guy in this list. Most mentioned MTU, but how I assure that the problem is just MTU, how I debug it? Here is my bridge configuration: Internet | | Gateway | | eth0 Ethernet Bridge | eth1 | H u b ( one normal hub

Hi there, I am getting very low throughput (around 0.29Mbps) while running netperf benchmark for guest to guest communication on a single physical host. To analyse where the time is spent in hypervisor I wanna use profiling. Please help me choosing good profiler according to my requirments. Should it be better in my case, Xentrace, gprof, xenoprof  or Oprofile. Is it possible to use some vtune
