* net-sched: add dynamically sized qdisc class hash helpersPatrick McHardy2008-07-061-0/+104
| | | | | | | | | | | | Currently all qdiscs which allow to create classes uses a fixed sized hash table with size 16 to hash the classes. This causes a large bottleneck when using thousands of classes and unbound filters. Add helpers for dynamically sized class hashes to fix this. The following patches will convert the qdiscs to use them. Signed-off-by: Patrick McHardy <kaber@trash.net> Signed-off-by: David S. Miller <davem@davemloft.net>

| * bridge: fix use-after-free in br_cleanup_bridges()Patrick McHardy2008-07-031-3/+7
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Unregistering a bridge device may cause virtual devices stacked on the bridge, like vlan or macvlan devices, to be unregistered as well. br_cleanup_bridges() uses for_each_netdev_safe() to iterate over all devices during cleanup. This is not enough however, if one of the additionally unregistered devices is next in the list to the bridge device, it will get freed as well and the iteration continues on the freed element. Restart iteration after each bridge device removal from the beginning to fix this, similar to what rtnl_link_unregister() does.

| * | netfilter: nf_conntrack_tcp: fixing to check the lower bound of valid ACKJozsef Kadlecsik2008-06-301-6/+7
| |/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Lost connections was reported by Thomas Bätzler (running 2.6.25 kernel) on the netfilter mailing list (see the thread "Weird nat/conntrack Problem with PASV FTP upload"). He provided tcpdump recordings which helped to find a long lingering bug in conntrack. In TCP connection tracking, checking the lower bound of valid ACK could lead to mark valid packets as INVALID because: - We have got a "higher or equal" inequality, but the test checked the "higher" condition only; fixed. - If the packet contains a SACK option, it could occur that the ACK value was before the left edge of our (S)ACK "window": if a previous packet from the other party intersected the right edge of the window of the receiver, we could move forward the window parameters beyond accepting a valid ack. Therefore in this patch we check the rightmost SACK edge instead of the ACK value in the lower bound of valid (S)ACK test.

This patch therefore builds all enabled algorithms into the mac80211 module. The user interface for the rate control algorithms changes as follows: - first the user can choose which algorithms to enable (currently only MAC80211_RC_PID is available) - if more than one algorithm is enabled (currently not possible since only one algorithm is present) the user then chooses the default one Note: - MAC80211_RC_PID is always enables for CONFIG_EMBEDDED=n Technical changes: - all selected algorithms get into the mac80211 module - net/mac80211/Makefile can now become much less complicated - support for rc80211_pid_algo.c being modular is no longer required - this includes unexporting mesh_plink_broken Signed-off-by: Adrian Bunk <bunk@kernel.org> Signed-off-by: John W.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Add GVRP support for dynamically registering VLANs with switches. By default GVRP is disabled because we only support the applicant-only participant model, which means it should not be enabled on vlans that are members of a bridge. Since there is currently no way to cleanly determine that, the user is responsible for enabling it. The code is pretty small and low impact, its wrapped in a config option though because it depends on the GARP implementation and the STP core.
