Raw Normal View History

Linux-2.6.12-rc2 Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!

bridge: send correct MTU value in PMTU (revised) When bridging interfaces with different MTUs, the bridge correctly chooses the minimum of the MTUs of the physical devices as the bridges MTU. But when a frame is passed which fits through the incoming, but not through the outgoing interface, a "Fragmentation Needed" packet is generated. However, the propagated MTU is hardcoded to 1500, which is wrong in this situation. The sender will repeat the packet again with the same frame size, and the same problem will occur again. Instead of sending 1500, the (correct) MTU value of the bridge is now sent via PMTU. To achieve this, the corresponding rtable structure is stored in its net_bridge structure. Modified to get rid of fake_net_device as well. Signed-off-by: Simon Wunderlich <siwu@hrz.tu-chemnitz.de> Signed-off-by: Stephen Hemminger <shemminger@linux-foundation.org> Signed-off-by: David S.

[NET]: Make the device list and device lookups per namespace. This patch makes most of the generic device layer network namespace safe. This patch makes dev_base_head a network namespace variable, and then it picks up a few associated variables. The functions: dev_getbyhwaddr dev_getfirsthwbytype dev_get_by_flags dev_get_by_name __dev_get_by_name dev_get_by_index __dev_get_by_index dev_ioctl dev_ethtool dev_load wireless_process_ioctl were modified to take a network namespace argument, and deal with it. vlan_ioctl_set and brioctl_set were modified so their hooks will receive a network namespace argument. So basically anthing in the core of the network stack that was affected to by the change of dev_base was modified to handle multiple network namespaces. The rest of the network stack was simply modified to explicitly use &init_net the initial network namespace. This can be fixed when those components of the network stack are modified to handle multiple network namespaces. For now the ifindex generator is left global. Fundametally ifindex numbers are per namespace, or else we will have corner case problems with migration when we get that far. At the same time there are assumptions in the network stack that the ifindex of a network device won't change. Making the ifindex number global seems a good compromise until the network stack can cope with ifindex changes when you change namespaces, and the like. Signed-off-by: Eric W.

Linux-2.6.12-rc2 Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!

bridge: add support for user mode STP This patchset based on work by Aji_Srinivas@emc.com provides allows spanning tree to be controled from userspace. Like hotplug, it uses call_usermodehelper when spanning tree is enabled so there is no visible API change. If call to start usermode STP fails it falls back to existing kernel STP.

So in that case allow the bridge mac address to be set to any of the existing interfaces. I don't want to allow any arbitrary value and confuse STP.
