X722 fixes an issue from X710 where TX descriptor WB would not happen if the interrupts were disabled. In order for the write backs to happen a bit needs to be set in the dynamic interrupt control register called WB_ON_ITR. With this feature, the SW driver need not arm SW interrupts to work around the issue in X710.

X722 uses the admin queue to configure RSS. This patch adds the necessary flow changes to configure RSS through AQ. It also adds the separate VMDQ2 lookup tables and hash key programming for X722. X722 also exposes a different set of PCTYPES for RSS, this patch accommodates those changes.

Pablo Neira Ayuso says: ==================== Netfilter updates for net-next The following patchset contains Netfilter updates for net-next, they are: 1) A couple of cleanups for the netfilter core hook from Eric Biederman. 2) Net namespace hook registration, also from Eric. This adds a dependency with the rtnl_lock. This should be fine by now but we have to keep an eye on this because if we ever get the per-subsys nfnl_lock before rtnl we have may problems in the future. But we have room to remove this in the future by propagating the complexity to the clients, by registering hooks for the init netns functions. 3) Update nf_tables to use the new net namespace hook infrastructure, also from Eric. 4) Three patches to refine and to address problems from the new net namespace hook infrastructure. 5) Switch to alternate jumpstack in xtables iff the packet is reentering. This only applies to a very special case, the TEE target, but Eric Dumazet reports that this is slowing down things for everyone else. So let's only switch to the alternate jumpstack if the tee target is in used through a static key. This batch also comes with offline precalculation of the jumpstack based on the callchain depth. From Florian Westphal. 6) Minimal SCTP multihoming support for our conntrack helper, from Michal Kubecek. 7) Reduce nf_bridge_info per skbuff scratchpad area to 32 bytes, from Florian Westphal. 8) Fix several checkpatch errors in bridge netfilter, from Bernhard Thaler. 9) Get rid of useless debug message in ip6t_REJECT, from Subash Abhinov. ==================== Signed-off-by: NDavid S.

lwtunnel encap is applied for forwarded packets, but not for locally-generated packets. This is because the output function is not overridden in __mkroute_output, unlike it is in __mkroute_input. The lwtunnel state is correctly set on the rth through the call to rt_set_nexthop, so all that needs to be done is to override the dst output function to be lwtunnel_output if there is lwtunnel state present and it requires output redirection.

In the locally-generated packet path skb->protocol may not be set and this is required for the lwtunnel encap in order to get the lwtstate. This would otherwise have been set by ip_output or ip6_output so set skb->protocol prior to calling the lwtunnel encap function. Additionally set skb->dev in case it is needed further down the transmit path. Signed-off-by: NRobert Shearman <rshearma@brocade.com> Signed-off-by: NDavid S. Miller <davem@davemloft.net>

Since the introduction of the BPF action in d23b8ad8 ("tc: add BPF based action"), late binding was not working as expected. I.e. setting the action part for a classifier only via 'bpf index <num>', where <num> is the index of an existing action, is being rejected by the kernel due to other missing parameters. It doesn't make sense to require these parameters such as BPF opcodes etc, as they are not going to be used anyway: in this case, they're just allocated/parsed and then freed again w/o doing anything meaningful. Instead, parse and verify the remaining parameters *after* the test on tcf_hash_check(), when we really know that we're dealing with creation of a new action or replacement of an existing one and where late binding is thus irrelevant. After patch, test case is now working: FOO="1,6 0 0 4294967295," tc actions add action bpf bytecode "$FOO" tc filter add dev foo parent 1: bpf bytecode "$FOO" flowid 1:1 action bpf index 1 tc actions show action bpf action order 0: bpf bytecode '1,6 0 0 4294967295' default-action pipe index 1 ref 2 bind 1 tc filter show dev foo filter protocol all pref 49152 bpf filter protocol all pref 49152 bpf handle 0x1 flowid 1:1 bytecode '1,6 0 0 4294967295' action order 1: bpf bytecode '1,6 0 0 4294967295' default-action pipe index 1 ref 2 bind 1 Late binding of a BPF action can be useful for preloading maps (e.g. before they hit traffic) in case of eBPF programs, or to share a single eBPF action with multiple classifiers.

Straightforward patch to add GRO processing to virtio_net. napi_complete_done() usage allows more aggressive aggregation, opted-in by setting /sys/class/net/xxx/gro_flush_timeout Tested: Setting /sys/class/net/xxx/gro_flush_timeout to 1000 nsec, Rick Jones reported following results. One VM of each on a pair of OpenStack compute nodes with E5-2650Lv3 CPUs and Intel 82599ES-based NICs. So, two "before" and two "after" VMs. The OpenStack compute nodes were running OpenStack Kilo, with VxLAN encapsulation being used through OVS so no GRO coming-up the host stack. The compute nodes themselves were running a 3.14-based kernel. Single-stream netperf, CPU utilizations and thus service demands are based on intra-guest reported CPU.

Add skb->hash to the __sk_buff offset map, so it can be accessed from an eBPF program. We currently already do this for classic BPF filters, but not yet on eBPF, it might be useful as a demuxer in combination with helpers like bpf_clone_redirect(), toy example: __section("cls-lb") int ingress_main(struct __sk_buff *skb) { unsigned int which = 3 + (skb->hash & 7); /* bpf_skb_store_bytes(skb, ...); */ /* bpf_l{3,4}_csum_replace(skb, ...); */ bpf_clone_redirect(skb, which, 0); return -1; } I was thinking whether to add skb_get_hash(), but then concluded the raw skb->hash seems fine in this case: we can directly access the hash w/o extra eBPF helper function call, it's filled out by many NICs on ingress, and in case the entropy level would not be sufficient, people can still implement their own specific sw fallback hash mix anyway.

Tom Herbert says: ==================== ipv6: Turn on auto IPv6 flow labels by default BSD (MacOS) has already turned on flow labels by default and this does not seem to be causing any problems in the Internet. Let's go ahead and turn them on by default. We'll continue to monitor for any devices start choking on them. Flow labels are important since they are the desired solution for network devices to perform ECMP and RSS (RFC6437 and RFC6438). Traditionally, devices perform a 5-tuple hash on packets that includes port numbers. For the most part, these devices can only compute 5-tuple hashes for TCP and UDP. This severely limits our ability to get good network load balancing for other protocols (IPIP, GRE,ESP, etc.), and hence we are limited in using other protocols. Unfortunately, this method is accepted as the de facto standard to the extent that there are several proposals to encapsulate protocols in UDP _just_ for the purposes for getting ECMP to work. With hosts generating flow labels and devices taking them as input into ECMP (several already do), we can start to fix this fundamental problem. This patch set: - Changes IPV6_FLOWINFO sockopt to be opt-out of flow labels for connections rather than opt-in - Disable flow label state ranges sysctl by default - Enable auto flow labels sysctl by default v2: - Added functions to create an skb->hash based on flowi4 and flowi6. These are called in output path when creating a packet - Call skb_get_hash_flowi6 in ip6_make_flowlabel - Implement the auto_flowlabels sysctl as a mode for auto flowlabels. There are four modes which correspond to flow labels being enabled and whether socket option can be used to opt in or opt out of using them ==================== Signed-off-by: NDavid S.

Per RFC6437 stateful flow labels (e.g. labels set by flow label manager) cannot "disturb" nodes taking part in stateless flow labels. While the ranges only reduce the flow label entropy by one bit, it is conceivable that this might bias the algorithm on some routers causing a load imbalance.
