netem: revised correlated loss generator

2011-02-25T06:11:56+00:00

This is a patch originated with Stefano Salsano and Fabio Ludovici. It provides several alternative loss models for use with netem. This patch adds two state machine based loss models.

Revert "sch_netem: Remove classful functionality"

2011-02-25T06:11:55+00:00

Many users have wanted the old functionality that was lost to be able to use pfifo as inner qdisc for netem. The reason that netem could not be classful with the older API was because of the limitations of the old dequeue/requeue interface; now that qdisc API has a peek function, there is no longer a problem with using any inner qdisc's. This reverts commit 02201464119334690fe209849843881b8e9cfa9f. Signed-off-by: Stephen Hemminger Signed-off-by: David S. Miller

netem: define NETEM_DIST_MAX

2011-02-25T06:11:54+00:00

Rather than magic constant in code, expose the maximum size of packet distribution table in API. In iproute2, q_netem defines MAX_DIST as 16K already. Signed-off-by: Stephen Hemminger Signed-off-by: David S. Miller

netem: use vmalloc for distribution table

2011-02-25T06:11:54+00:00

The netem probability table can be large (up to 64K bytes) which may be too large to allocate in one contiguous chunk. Signed-off-by: Stephen Hemminger Signed-off-by: David S. Miller

net_sched: accurate bytes/packets stats/rates

2011-01-21T07:31:33+00:00

In commit 44b8288308ac9d (net_sched: pfifo_head_drop problem), we fixed a problem with pfifo_head drops that incorrectly decreased sch->bstats.bytes and sch->bstats.packets Several qdiscs (CHOKe, SFQ, pfifo_head, ...) are able to drop a previously enqueued packet, and bstats cannot be changed, so bstats/rates are not accurate (over estimated) This patch changes the qdisc_bstats updates to be done at dequeue() time instead of enqueue() time. bstats counters no longer account for dropped frames, and rates are more correct, since enqueue() bursts dont have effect on dequeue() rate.
