* net: cdc_ncm: remove descriptor pointersBjørn Mork2013-11-021-3/+1
| | | | | | | | | header_desc was completely unused and union_desc was never used outside cdc_ncm_bind_common. Cc: Alexey Orishko <alexey.orishko@gmail.com> Signed-off-by: Bjørn Mork <bjorn@mork.no> Signed-off-by: David S. Miller <davem@davemloft.net>

| | | | | | | | | | | | | Moving the call to cdc_ncm_setup() after the endpoint setup removes the last remaining reference to ncm_parm outside cdc_ncm_setup. Collecting all the ncm_parm based calculations in cdc_ncm_setup improves readability. Cc: Alexey Orishko <alexey.orishko@gmail.com> Signed-off-by: Bjørn Mork <bjorn@mork.no> Signed-off-by: David S.

* net: cdc_ncm: remove tx_speed and rx_speed fieldsBjørn Mork2013-11-021-2/+0
| | | | | | | | | | | | | | | These fields are only used to prevent printing the same speeds multiple times if we receive multiple identical speed notifications. The value of these printk's is questionable, and even more so when we filter out some of the notifications sent us by the firmware. If we are going to print any of these, then we should print them all. Removing little used fields is a bonus.

* net: cdc_ncm: remove redundant netdev fieldBjørn Mork2013-11-021-2/+1
| | | | | | | | | | | | | | Too many pointers back and forth are likely to confuse developers, creating subtle bugs whenever we forget to syncronize them all. As a usbnet driver, we should stick with the standard struct usbnet fields as much as possible. The netdevice is one such field.

Joseph provides a single patch against vxlan which removes the burden from the NIC drivers to check if the vxlan driver is enabled in the kernel and also makes available the vxlan headrooms to the drivers. Jacob provides majority of the patches, with patches against net, ixgbe and ixgbevf. His net patch adds might_sleep() call to napi_disable so that every use of napi_disable during atomic context will be visible. Then Jacob provides a patch to fix qv_lock_napi call in ixgbe_napi_disable_all. The other ixgbe patches cleanup ixgbe_check_minimum_link function to correctly show that there are some minor loss of encoding, even though we don't calculate it and remove unnecessary duplication of PCIe bandwidth display. Lastly, Jacob provides 4 patches against ixgbevf to add ixgbevf_rx_skb in line with how ixgbe handles the variations on how packets can be received, adds support in order to track how many packets were cleaned during busy poll as part of the extended statistics. Wei Yongjun provides a fix for i40e to return -ENOMEN in the memory allocation error handling case instead of returning 0, as done elsewhere in this function. ==================== Signed-off-by: David S.

| * net: add might_sleep() call to napi_disableJacob Keller2013-10-291-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | napi_disable uses an msleep() call to wait for outstanding napi work to be finished after setting the disable bit. It does not always sleep incase there was no outstanding work. This resulted in a rare bug in ixgbe_down operation where a napi_disable call took place inside of a local_bh_disable()d context. In order to enable easier detection of future sleep while atomic BUGs, this patch adds a might_sleep() call, so that every use of napi_disable during atomic context will be visible.

* | net: sched: cls_bpf: add BPF-based classifierDaniel Borkmann2013-10-291-0/+14
|/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

As rt6_nexthop() prefers rt6i_gateway only for gatewayed routes this causes a problem for users like IPVS, xt_TEE and RAW(hdrincl) if they want to use different address for routing compared to the destination address. Another case is when redirect can create RTF_DYNAMIC route without RTF_GATEWAY flag, we ignore the rt6i_gateway in rt6_nexthop(). Fix the above problems by considering the rt6i_gateway if present, so that traffic routed to address on local subnet is not wrongly diverted to the destination address.

But there are many more and it's impractical to annotate them all. First of all, we don't want to invoke the OOM killer when the failed allocation is gracefully handled, so defer the actual kill to the end of the fault handling as well. This simplifies the code quite a bit for added bonus. Second, since a failed allocation might not be the abrupt end of the fault, the memcg OOM handler needs to be re-entrant until the fault finishes for subsequent allocation attempts. If an allocation is attempted after the task already OOMed, allow it to bypass the limit so that it can quickly finish the fault and invoke the OOM killer.
