2013-12-17pkt_sched: fq: more robust memory allocationEric Dumazet
This patch brings NUMA support and automatic fallback to vmalloc() in case kmalloc() failed to allocate FQ hash table. NUMA support depends on XPS being setup for the device before qdisc allocation.

2013-12-11net: sched: tbf: fix the calculation of max_sizeYang Yingliang
Current max_size is caluated from rate table. Now, the rate table has been replaced and it's wrong to caculate max_size based on this rate table. It can lead wrong calculation of max_size. The burst in kernel may be lower than user asked, because burst may gets some loss when transform it to buffer(E.g. "burst 40kb rate 30mbit/s") and it seems we cannot avoid this loss. Burst's value(max_size) based on rate table may be equal user asked. If a packet's length is max_size, this packet will be stalled in tbf_dequeue() because its length is above the burst in kernel so that it cannot get enough tokens. The max_size guards against enqueuing packet sizes above q->buffer "time" in tbf_enqueue(). To make consistent with the calculation of tokens, this patch add a helper psched_ns_t2l() to calculate burst(max_size) directly to fix this problem. After this fix, we can support to using 64bit rates to calculate burst as well.

2013-11-15pkt_sched: fq: fix pacing for small framesEric Dumazet
For performance reasons, sch_fq tried hard to not setup timers for every sent packet, using a quantum based heuristic : A delay is setup only if the flow exhausted its credit. Problem is that application limited flows can refill their credit for every queued packet, and they can evade pacing. This problem can also be triggered when TCP flows use small MSS values, as TSO auto sizing builds packets that are smaller than the default fq quantum (3028 bytes) This patch adds a 40 ms delay to guard flow credit refill.

2013-11-14pkt_sched: fq: change classification of control packetsMaciej Żenczykowski
Initial sch_fq implementation copied code from pfifo_fast to classify a packet as a high prio packet. This clashes with setups using PRIO with say 7 bands, as one of the band could be incorrectly (mis)classified by FQ. Packets would be queued in the 'internal' queue, and no pacing ever happen for this special queue.

2013-10-29net: sched: cls_bpf: add BPF-based classifierDaniel Borkmann
This work contains a lightweight BPF-based traffic classifier that can serve as a flexible alternative to ematch-based tree classification, i.e. now that BPF filter engine can also be JITed in the kernel. Naturally, tc actions and policies are supported as well with cls_bpf. Multiple BPF programs/filter can be attached for a class, or they can just as well be written within a single BPF program, that's really up to the user how he wishes to run/optimize the code, e.g. also for inversion of verdicts etc. The notion of a BPF program's return/exit codes is being kept as follows: 0: No match -1: Select classid given in "tc filter ..." command else: flowid, overwrite the default one As a minimal usage example with iproute2, we use a 3 band prio root qdisc on a router with sfq each as leave, and assign ssh and icmp bpf-based filters to band 1, http traffic to band 2 and the rest to band 3. For the first two bands we load the bytecode from a file, in the 2nd we load it inline as an example: echo 1 > /proc/sys/net/core/bpf_jit_enable tc qdisc del dev em1 root tc qdisc add dev em1 root handle 1: prio bands 3 priomap 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 tc qdisc add dev em1 parent 1:1 sfq perturb 16 tc qdisc add dev em1 parent 1:2 sfq perturb 16 tc qdisc add dev em1 parent 1:3 sfq perturb 16 tc filter add dev em1 parent 1: bpf run bytecode-file /etc/tc/ssh.bpf flowid 1:1 tc filter add dev em1 parent 1: bpf run bytecode-file /etc/tc/icmp.bpf flowid 1:1 tc filter add dev em1 parent 1: bpf run bytecode-file /etc/tc/http.bpf flowid 1:2 tc filter add dev em1 parent 1: bpf run bytecode "`bpfc -f tc -i misc.ops`" flowid 1:3 BPF programs can be easily created and passed to tc, either as inline 'bytecode' or 'bytecode-file'. There are a couple of front-ends that can compile opcodes, for example: 1) People familiar with tcpdump-like filters: tcpdump -iem1 -ddd port 22 | tr '\n' ',' > /etc/tc/ssh.bpf 2) People that want to low-level program their filters or use BPF extensions that lack support by libpcap's compiler: bpfc -f tc -i ssh.ops > /etc/tc/ssh.bpf ssh.ops example code: ldh [12] jne #0x800, drop ldb [23] jneq #6, drop ldh [20] jset #0x1fff, drop ldxb 4 * ([14] & 0xf) ldh [%x + 14] jeq #0x16, pass ldh [%x + 16] jne #0x16, drop pass: ret #-1 drop: ret #0 It was chosen to load bytecode into tc, since the reverse operation, tc filter list dev em1, is then able to show the exact commands again. Possible follow-up work could also include a small expression compiler for iproute2. Tested with the help of bmon. This idea came up during the Netfilter Workshop 2013 in Copenhagen.

The transition from markov state "3 => lost packets within a burst period" to "1 => successfully transmitted packets within a gap period" has no *additional* loss event. The loss already happen for transition from 1 -> 3, this additional loss will make things go wild. E.g. transition probabilities: p13: 10% p31: 100% Expected: Ploss = p13 / (p13 + p31) Ploss = ~9.09% ... but it isn't. Even worse: we get a double loss - each time.
