Rename some functions that used to be invoked upon ndo_open/stop and are now invoked upon create/destroy_netdev() in order to better hint their place in the flow. Change some functions location in the file so that functions involved in ndo_open/stop flow will not be interleaved with other functions. This is a cosmetic change, no logical change here.

Create/destroy TIRs, TISs and flow tables upon PCI probe/remove rather than upon the netdev ndo_open/stop. Upon ndo_stop(), redirect all RX traffic to the (lately introduced) "Drop RQ" and then close only the RX/TX rings, leaving the TIRs, TISs and flow tables alive.

Generally an RX packet flows through the following objects: Flow table --> TIR --> RQT --> RQ Where: - TIR stands for "Transport Interface Receive", defining the RSS and LRO paramaters. - RQT stands for "RQ Table", implementing the RSS indirection table. - RQ stands for "Receive Queue" For flows that do not need LRO, nor RSS, the driver made a shortcut to the above RX flow by pointing to the RQ directly from the TIR, yielding this flow: Flow table --> TIR --> RQ In this commit we remove this shortcut by "inserting" a single-RQ RQT between the TIR and the RQ, i.e RX packets will reach the same RQ but will go through an RQT of size 1, pointing to just a single RQ. This way the RX traffic re-direction to/from the "Drop RQ" will be more uniform (AKA "one flow"), as it will involve only RQTs re-direction and no TIRs re-direction.

We recently changed this code from returning NULL to returning ERR_PTR. There are some left over NULL assignments which we can remove. We can preserve the error code from ip_route_output() instead of always returning -ENODEV. Also these functions use a mix of gotos and direct returns. There is no cleanup necessary so I changed the gotos to direct returns.

Yuval Mintz says: ==================== bnx2x, cnic, bnx2fc: add support for BD Commit 230d00eb ("bnx2x: new Multi-function mode - BD") added support for a new multi-function mode, but it added only the support required by bnx2x for L2 interfaces. This adds the required changes to support the new multi-function mode in the offloaded storage protocols. Dave, Please consider applying this series to `net-next'. Do notice that this involves non-networking driver changes - but sending this as a single series seemed like the best approach as we had to have bnx2x changes to support the new functionality. If this is problematic, please tell us what's the preferred solution here.

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.

由 Robert Shearman 提交于
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.

Before this patch when a vid was not specified, the entry was added with vid 0 which is useless when vlan_filtering is enabled. This patch makes the entry to be added on all configured vlans when vlan filtering is enabled and respectively deleted from all, if the entry vid is 0. This is also closer to the way fdb works with regard to vid 0 and vlan filtering. Example: Setup: $ bridge vlan add vid 256 dev eth4 $ bridge vlan add vid 1024 dev eth4 $ bridge vlan add vid 64 dev eth3 $ bridge vlan add vid 128 dev eth3 $ bridge vlan port vlan ids eth3 1 PVID Egress Untagged 64 128 eth4 1 PVID Egress Untagged 256 1024 $ echo 1 > /sys/class/net/br0/bridge/vlan_filtering Before: $ bridge mdb add dev br0 port eth3 grp 239.0.0.1 $ bridge mdb dev br0 port eth3 grp 239.0.0.1 temp After: $ bridge mdb add dev br0 port eth3 grp 239.0.0.1 $ bridge mdb dev br0 port eth3 grp 239.0.0.1 temp vid 1 dev br0 port eth3 grp 239.0.0.1 temp vid 128 dev br0 port eth3 grp 239.0.0.1 temp vid 64 Signed-off-by: NSatish Ashok <sashok@cumulusnetworks.com> Signed-off-by: NNikolay Aleksandrov <nikolay@cumulusnetworks.com> Signed-off-by: NDavid S.

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.
