Raw Normal View History

Linux-2.6.12-rc2 Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!

[NET_SCHED]: Fix endless loops caused by inaccurate qlen counters (part 1) There are multiple problems related to qlen adjustment that can lead to an upper qdisc getting out of sync with the real number of packets queued, leading to endless dequeueing attempts by the upper layer code. All qdiscs must maintain an accurate q.qlen counter. There are basically two groups of operations affecting the qlen: operations that propagate down the tree (enqueue, dequeue, requeue, drop, reset) beginning at the root qdisc and operations only affecting a subtree or single qdisc (change, graft, delete class). Since qlen changes during operations from the second group don't propagate to ancestor qdiscs, their qlen values become desynchronized. This patch adds a function to propagate qlen changes up the qdisc tree, optionally calling a callback function to perform qdisc-internal maintenance when the child qdisc becomes empty. The follow-up patches will convert all qdiscs to use this function where necessary. Noticed by Timo Steinbach <tsteinbach@astaro.com>.

[PKT_SCHED]: Generic queue management interface for qdiscs using internal skb queues Implements an interface to be used by leaf qdiscs maintaining an internal skb queue. The interface maintains a backlog in bytes additionaly to the skb_queue_len() maintained by the queue itself. Relevant statistics get incremented automatically. Every function comes in two variants, one assuming Qdisc->q is used as queue and the second taking a sk_buff_head as argument. Be aware that, if you use multiple queues, you still have to maintain the Qdisc->q.qlen counter yourself. Signed-off-by: Thomas Graf <tgraf@suug.ch> Signed-off-by: David S.

[NET_SCHED]: Cleanup L2T macros and handle oversized packets Change L2T (length to time) macros, in all rate based schedulers, to call a common function qdisc_l2t() that does the rate table lookup. This function handles if the packet size lookup is larger than the rate table, which often occurs with TSO enabled.

[NET_SCHED]: Making rate table lookups more flexible. This is done in order to, add support to changing the rate table to use the upper-boundry L2T (length to time) value. Currently we use the lower-boundry, which result in under-estimating the actual bandwidth usage. Extend the tc_ratespec struct, with two parameters: 1) "cell_align" that allow adjusting the alignment of the rate table. 2) "overhead" that allow adding a packet overhead before the lookup.
