| * bridge: bad error handling when adding invalid ether addressStephen Hemminger2009-03-261-1/+0
| | | | | | | | | | | | | | | | | | | | | | | | This fixes an crash when empty bond device is added to a bridge. If an interface with invalid ethernet address (all zero) is added to a bridge, then bridge code detects it when setting up the forward databas entry. But the error unwind is broken, the bridge port object can get freed twice: once when ref count went to zeo, and once by kfree. Since object is never really accessible, just free it.

* | netfilter: fix nf_logger name in ebt_ulog.Eric Leblond2009-03-261-1/+1
| | | | | | | | | | | | | | | | | | This patch renames the ebt_ulog nf_logger from "ulog" to "ebt_ulog" to be in sync with other modules naming. As this name was currently only used for informational purpose, the renaming should be harmless. Signed-off-by: Eric Leblond <eric@inl.fr> Signed-off-by: David S. Miller <davem@davemloft.net>

* | | netlink: change nlmsg_notify() return value logicPablo Neira Ayuso2009-02-251-1/+2
|/ / | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch changes the return value of nlmsg_notify() as follows: If NETLINK_BROADCAST_ERROR is set by any of the listeners and an error in the delivery happened, return the broadcast error; else if there are no listeners apart from the socket that requested a change with the echo flag, return the result of the unicast notification. Thus, with this patch, the unicast notification is handled in the same way of a broadcast listener that has set the NETLINK_BROADCAST_ERROR socket flag. This patch is useful in case that the caller of nlmsg_notify() wants to know the result of the delivery of a netlink notification (including the broadcast delivery) and take any action in case that the delivery failed. For example, ctnetlink can drop packets if the event delivery failed to provide reliable logging and state-synchronization at the cost of dropping packets. This patch also modifies the rtnetlink code to ignore the return value of rtnl_notify() in all callers. The function rtnl_notify() (before this patch) returned the error of the unicast notification which makes rtnl_set_sk_err() reports errors to all listeners. This is not of any help since the origin of the change (the socket that requested the echoing) notices the ENOBUFS error if the notification fails and should resync itself.

* netfilter 03/09: bridge: Disable PPPOE/VLAN processing by defaultHerbert Xu2009-01-131-4/+4
| | | | | | | | | | | | | | | | | | | | | | | | The PPPOE/VLAN processing code in the bridge netfilter is broken by design. The VLAN tag and the PPPOE session ID are an integral part of the packet flow information, yet they're completely ignored by the bridge netfilter. This is potentially a security hole as it treats all VLANs and PPPOE sessions as the same. What's more, it's actually broken for PPPOE as the bridge netfilter tries to trim the packets to the IP length without adjusting the PPPOE header (and adjusting the PPPOE header isn't much better since the PPPOE peer may require the padding to be present). Therefore we should disable this by default. It does mean that people relying on this feature may lose networking depending on how their bridge netfilter rules are configured. However, IMHO the problems this code causes are serious enough to warrant this.

So what happened was that it would simply take the TSO status of the last constituent device. This patch extends it to support both conjunctions and disjunctions under the new name of netdev_increment_features. It also adds a new function netdev_fix_features which does the sanity checking that usually occurs upon registration. This ensures that the computation doesn't result in an illegal combination since this checking is absent when the change is initiated via ethtool.

| | | | | | | | | | | | | | | | | | The function signatures for Xtables extensions have grown over time. It involves a lot of typing/replication, and also a bit of stack space even if they are not used. Realize an NFWS2008 idea and pack them into structs. The skb remains outside of the struct so gcc can continue to apply its optimizations. This patch does this for match extensions' match functions. A few ambiguities have also been addressed. The "offset" parameter for example has been renamed to "fragoff" (there are so many different offsets already) and "protoff" to "thoff" (there is more than just one protocol here, so clarify).
