netfilter: ebtables: make broute table work again

2011-01-11T22:55:51Z

broute table init hook sets up the "br_should_route_hook" pointer, which then gets called from br_input. commit a386f99025f13b32502fe5dedf223c20d7283826 (bridge: add proper RCU annotation to should_route_hook) introduced a typedef, and then changed this to: br_should_route_hook_t *rhook; [..] rhook = rcu_dereference(br_should_route_hook); if (*rhook(skb)) problem is that "br_should_route_hook" contains the address of the function, so calling *rhook() results in kernel panic.

bridge: add proper RCU annotation to should_route_hook

2010-11-15T19:13:16Z

Add br_should_route_hook_t typedef, this is the only way we can get a clean RCU implementation for function pointer. Move route_hook to location where it is used. Signed-off-by: Eric Dumazet Signed-off-by: Stephen Hemminger Signed-off-by: David S. Miller

net: replace hooks in __netif_receive_skb V5

2010-06-02T14:11:15Z

What this patch does is it removes two receive frame hooks (for bridge and for macvlan) from __netif_receive_skb. These are replaced them with a single hook for both. It only supports one hook per device because it makes no sense to do bridging and macvlan on the same device. Then a network driver (of virtual netdev like macvlan or bridge) can register an rx_handler for needed net device. Signed-off-by: Jiri Pirko Signed-off-by: Stephen Hemminger Signed-off-by: David S.

bridge: forwarding table information for >256 devices

2008-05-02T23:53:33Z

The forwarding table binary interface (my bad choice), only exposes the port number of the first 8 bits. The bridge code was limited to 256 ports at the time, but now the kernel supports up 1024 ports, so the upper bits are lost when doing: brctl showmacs The fix is to squeeze the extra bits into small hole left in data structure, to maintain binary compatiablity.

[NETFILTER]: Replace sk_buff ** with sk_buff *

With all the users of the double pointers removed, this patch mops up by finally replacing all occurances of sk_buff ** in the netfilter API by sk_buff *. Signed-off-by: Herbert Xu Signed-off-by: David S. Miller

[NET]: Make the device list and device lookups per namespace.

2007-10-10T23:49:10Z

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.

bridge: eliminate call by reference

2007-04-26T05:28:44Z

Change the bridging hook to be simple function with return value rather than modifying the skb argument. This could generate better code and is cleaner. Signed-off-by: Stephen Hemminger

[BRIDGE]: Fix oops when mangling and brouting and tcpdumping packets

2004-08-25T09:35:34Z

The ebtables brouting chain, traversed through the call br_should_route_hook(), can alter a packet. The redirect target does this, f.e., to change the MAC destination. Bart discovered this and proposed a patch; this is a revised version. This version cleans up the handle_bridge code in net/core/dev.c as well as getting rid of extra rcu_read_lock and only does the br_port checking once.
