Currently when PRIO is configured to use N bands, it lets the packets be directed to any of the bands 0..N-1. However, PRIO attaches a fifo qdisc only to the bands that appear in the priomap; the rest of the N bands remain with a noop qdisc attached. This patch changes PRIO's behavior so that it attaches a fifo qdisc to all of the N bands. Signed-off-by: NAmnon Aaronsohn <bla@cs.huji.ac.il> Signed-off-by: NDavid S. Miller <davem@davemloft.net>

This monster-patch tries to do the best job for unifying the data structures and backend interfaces for the three evil clones ip_tables, ip6_tables and arp_tables. In an ideal world we would never have allowed this kind of copy+paste programming... but well, our world isn't (yet?) ideal. o introduce a new x_tables module o {ip,arp,ip6}_tables depend on this x_tables module o registration functions for tables, matches and targets are only wrappers around x_tables provided functions o all matches/targets that are used from ip_tables and ip6_tables are now implemented as xt_FOOBAR.c files and provide module aliases to ipt_FOOBAR and ip6t_FOOBAR o header files for xt_matches are in include/linux/netfilter/, include/linux/netfilter_{ipv4,ipv6} contains compatibility wrappers around the xt_FOOBAR.h headers Based on this patchset we're going to further unify the code, gradually getting rid of all the layer 3 specific assumptions.

Here is a new feature for netem in 2.6.16. It adds the ability to randomly corrupt packets with netem. A version was done by Hagen Paul Pfeifer, but I redid it to handle the cases of backwards compatibility with netlink interface and presence of hardware checksum offload. It is useful for testing hardware offload in devices. Signed-off-by: NStephen Hemminger <shemminger@osdl.org> Signed-off-by: NDavid S. Miller <davem@davemloft.net>

If two packets were queued to be sent at the same time in the future, their order would be reversed. This would occur because the queue is traversed back to front, and a position is found by checking whether the new packet needs to be sent before the packet being examined. If the new packet is to be sent at the same time of a previous packet, it would end up before the old packet in the queue. This patch places packets in the correct order when they are queued to be sent at a same time in the future. Signed-off-by: NAndrea Bittau <a.bittau@cs.ucl.ac.uk> Signed-off-by: NDavid S.

Change netem to support packets getting reordered because of variations in delay. Introduce a special case version of FIFO that queues packets in order based on the netem delay. Since netem is classful, those users that don't want jitter based reordering can just insert a pfifo instead of the default. This required changes to generic skbuff code to allow finer grain manipulation of sk_buff_head. Insertion into the middle and reverse walk.

Introduces a new flag TC_RED_HARDDROP which specifies that if ECN marking is enabled packets should still be dropped once the average queue length exceeds the maximum threshold. This _may_ help to avoid global synchronisation during small bursts of peers advertising but not caring about ECN. Use this option very carefully, it does more harm than good if (qth_max - qth_min) does not cover at least two average burst cycles. The difference to the current behaviour, in which we'd run into the hard queue limit, is that due to the low pass filter of RED short bursts are less likely to cause a global synchronisation.

Since we are no longer depending on the default VQ to be always allocated we can leave it up to the user to actually create it.

Introduces a new red parameter set for use in equalize mode, although only the qavg variable and the idle period marker are being used for now this makes it possible to allow a separate parameter set to be used for equalize later on. The use of this separate parameter set fixes a bogus start of an idle period in gred_drop() which did start an idle period on the default VQ even if equalize mode was disabled.

Try to enqueue packets if we cannot associate it with a VQ, this basically means that the default VQ has not been set up yet.

Simplifies code a lot by separating the red algorithm and the queueing logic. We now differentiate between probability marks and forced marks but sum them together again to not break backwards compatibility. This brings GRED back to the level of RED and improves the accuracy of the averge queue length calculations when stab suggests a zero shift.

Introduces a function gred_change_table_def() acting as a central point to change the table definition. Adds missing validations for table definition: MAX_DPs > DPs > 0 and def_DP < DPs thus fixing possible invalid memory reference oopses. Only root could do it but having a typo crashing the machine is a bit hard.
