2015-09-23rocker: add FDB cleanup timerScott Feldman1-0/+42
Add a timer to each rocker switch to do FDB entry cleanup by ageing out expired entries. The timer scheduling algo is copied from the bridge driver, for the most part, to keep the firing of the timer to a minimum.

2015-09-23cls_bpf: further limit exec opcodes subsetDaniel Borkmann1-3/+0
Jamal suggested to further limit the currently allowed subset of opcodes that may be used by a direct action return code as the intention is not to replace the full action engine, but rather to have a minimal set that can be used in the fast-path on things like ingress for some features that cls_bpf supports. Classifiers can, of course, still be chained together that have direct action mode with those that have a full exec pass. For more complex scenarios that go beyond this minimal set here, the full tcf_exts_exec() path must be used.

2015-09-23cls_bpf: make binding to classid optionalDaniel Borkmann1-9/+8
The binding to a particular classid was so far always mandatory for cls_bpf, but it doesn't need to be. Therefore, lift this restriction as similarly done in other classifiers. Only a couple of qdiscs make use of class from the tcf_result, others don't strictly care, so let the user choose his needs (those that read out class can handle situations where it could be NULL). An explicit check for tcf_unbind_filter() is also not needed here, as the previous r->class was 0, so the xchg() will return that and therefore a callback to the qdisc's unbind_tcf() is skipped.

2015-09-23cls_bpf: also dump TCA_BPF_FLAGSDaniel Borkmann1-3/+8
In commit 43388da42a49 ("cls_bpf: introduce integrated actions") we have added TCA_BPF_FLAGS. We can also retrieve this information from the prog, dump it back to user space as well. It's useful in tc when displaying/dumping filter info. Also, remove tp from cls_bpf_prog_from_efd(), came in as a conflict from a rebase and it's unused here (later work may add it along with a real user).

2015-09-23sched, bpf: let stack handle !IFF_UP devs on bpf_clone_redirectDaniel Borkmann1-3/+0
Similarly as already the case in bpf_redirect()/skb_do_redirect() pair, let the stack deal with devs that are !IFF_UP. dev_forward_skb() as well as dev_queue_xmit() will free the skb and increment drop counter internally in such cases, so we can spare the condition in bpf_clone_redirect().

This BUS_ALIGN #define tries to allow 8 bit devices to work on a 16 bit bus by aligning addresses to 16 bit boundaries.
