Various drivers do skb_orphan() because they do not free transmitted skbs in a timely manner (causing apps which hit their socket limits to stall, socket close to hang, etc.). DaveM points out that there are advantages to doing it generally (it's more likely to be on same CPU than after xmit), and I couldn't find any new starvation issues in simple benchmarking here. This patch adds

I saw some big mistakes, here's the correct version : -------------------------------------------------------------------- void br_send_config_bpdu(struct net_bridge_port *p, struct bpdu *bpdu) { unsigned char buf[42]; buf[0] = bpdu->bpdu_header.protocol[0]; //0x00 buf[1] = bpdu->bpdu_header.protocol[1]; //0x00 buf[2] = bpdu->bpdu_header.version; //0x02 buf[3] =

Fixes message_age field update in config BPDUs. Also checks whether the BPDU message age has exceeded bridge max age before transmitting config BPDUs.

This hook is protected with the RCU, so simple if (br_should_route_hook) br_should_route_hook(...) is not enough on some architectures. Use the rcu_dereference/rcu_assign_pointer in this case.

Hi, I use the libbridge and an other lib (libnl) in a same project. I include the headers files of the two lib (libnl first and libbridgge after) and I've a conflict with the inclusion of linux/if.h (in libnl headers) and net/if.h (in libbridge.h), I've this error : /usr/include/net/if.h:45: error: parse error before numeric constant /usr/include/net/if.h:111: error: redefinition of

Dear Sir, I was trying to install bridge as we are installing scps gateway in our testbed.This requires us to install the bridge. Our Linux version is 2.4.18 ~3 and we are using redhat 7.2 Please let me know which is the bridge I should install and how to configure it. Before configuring the bridge what I should check in my configuration. Thanks for your time, Sincerely Rama ===== I hear

A malicious actor behind one bridge port may spam the kernel with packets with a random source MAC address, each of which will create an FDB entry, each of which is a dynamic allocation in the kernel. There are roughly 2^48 different MAC addresses, further limited by the rhashtable they are stored in to 2^31. Each entry is of the type struct net_bridge_fdb_entry, which is currently 128 bytes big.

Introduce a limit on the amount of learned FDB entries on a bridge, configured by netlink with a build time default on bridge creation in the kernel config. For backwards compatibility the kernel config default is disabling the limit (0). Without any limit a malicious actor may OOM a kernel by spamming packets with changing MAC addresses on their bridge port, so allow the bridge creator to limit

Hi, I'm trying to modify the stp kernel files in order to implements the RSTP. I've already modify the bpdu format like this : ------------------------------------------------------------------------------------------------------------------------------------ typedef struct { int topo_change = 0; int proposal = 0; int port_role[2] = {0,0} ; //role du port ?metteur du BPDU

The second part of my patch series to fix the handling of addr_assign_type for random MAC addresses. This contains the trival changes from random_ether_addr() to new eth_hw_addr_random() and code to reset the state to NET_ADDR_PERM as soon as the MAC get changed via .ndo_set_mac_address where eth_mac_addr wasn't used. Danny Kukawka (2): net: replace random_ether_addr() with

Hi all, With this series of patches, you can determine the owners of any type of I/Os. I ported the previous version to linux-2.6.26-rc2-mm1. This makes dm-ioband -- I/O bandwidth controller -- be able to control the Block I/O bandwidths even when it accepts delayed write requests. Dm-ioband can find the owner cgroup of each request. It is also possible that OpenVz team and NEC Uchida-san team

Sorry, if this question has been answered before, but I could not find out with a brief look. How can I set the MAC address for a bridge? The MAC address given for the bridge device seems to be the one it sends network packets with if the bridge device has an IP address set. Apparently the bridge starts with a zero MAC address and when the first interface is attached to it, it takes its MAC

I have been attempting to install the ipw2100.1.2.0 driver onto my laptop, but have run into some troubles. It requires IEEE 802.11, which I have downloaded the rpm for from sourceforge.
