[PKT_SCHED]: Fix missing qdisc_destroy() in qdisc_create_dflt()

2005-08-23T17:12:44+00:00

qdisc_create_dflt() is missing to destroy the newly allocated
default qdisc if the initialization fails resulting in leaks
of all kinds. The only caller in mainline which may trigger
this bug is sch_tbf.c in tbf_create_dflt_qdisc().

Note: qdisc_create_dflt() doesn't fulfill the official locking
      requirements of qdisc_destroy() but since the qdisc could
      never be seen by the outside world this doesn't matter
      and it can stay as-is until the locking of pkt_sched
      is cleaned up.

[PKT_SCHED]: em_meta: Kill TCF_META_ID_{INDEV,SECURITY,TCVERDICT}

More unusable TCF_META_* match types that need to get eliminated
before 2.6.13 goes out the door.

[PKT_SCHED]: Kill TCF_META_ID_REALDEV from meta ematch.

2005-07-22T18:47:25+00:00

It won't exist any longer when we shrink the SKB in 2.6.14,
and we should kill this off before anyone in userspace starts
using it.

[PKT_SCHED]: Reduce branch mispredictions in pfifo_fast_dequeue

2005-07-18T20:30:53+00:00

The current call to __qdisc_dequeue_head leads to a branch
misprediction for every loop iteration, the fact that the
most common priority is 2 makes this even worse.  This issue
has been brought up by Eric Dumazet 
but unlike his solution which was to manually unroll the loop,
this approach preserves the possibility to increase the number
of bands at compile time.

[NET]: move config options out to individual protocols

2005-07-12T04:13:56+00:00

Move the protocol specific config options out to the specific protocols.
With this change net/Kconfig now starts to become readable and serve as a
good basis for further re-structuring.

The menu structure is left almost intact, except that indention is
fixed in most cases. Most visible are the INET changes where several
"depends on INET" are replaced with a single ifdef INET / endif pair.

Several new files were created to accomplish this change - they are
small but serve the purpose that config options are now distributed
out where they belongs.

[NET]: Transform skb_queue_len() binary tests into skb_queue_empty()

2005-07-08T21:57:23+00:00

This is part of the grand scheme to eliminate the qlen
member of skb_queue_head, and subsequently remove the
'list' member of sk_buff.

Most users of skb_queue_len() want to know if the queue is
empty or not, and that's trivially done with skb_queue_empty()
which doesn't use the skb_queue_head->qlen member and instead
uses the queue list emptyness as the test.

[PKT_SCHED]: Blackhole queueing discipline

2005-07-05T22:29:16+00:00

Useful in combination with classful qdiscs to drop or
temporary disable certain flows, e.g. one could block
specific ds flows with dsmark.

Unlike the noop qdisc it can be controlled by the user and
statistic accounting is done.
