2017-11-05net: dsa: simplify tree reference countingVivien Didelot
DSA trees have a refcount used to automatically free the dsa_switch_tree structure once there is no switch devices inside of it. The refcount is incremented when a switch is added to the tree, and decremented when it is removed from it. But because of kref_init, the refcount is also incremented at initialization, and when looking up the tree from the list for symmetry. Thus the current code stores the number of switches plus one, and makes the switch registration more complex. To simplify the switch registration function, we reset the refcount to zero after initialization and don't increment it when looking up a tree.

Jakub Kicinski says: ==================== bpf: add offload as a first class citizen This series is my stab at what was discussed at a recent IOvisor bi-weekly call. The idea is to make the device translator run at the program load time. This makes the offload more explicit to the user space. It also makes it easy for the device translator to insert information into the original verifier log. v2: - include linux/bug.h instead of asm/bug.h; - rebased on top of Craig's verifier fix (no changes, the last patch just removes more code now). I checked the set doesn't conflict with Jiri's, Josef's or Roman's patches, but missed Craig's fix :( v1: - rename the ifindex member on load; - improve commit messages; - split nfp patches more. ==================== Signed-off-by: David S.

2017-11-05nfp: bpf: move to new BPF program offload infrastructureJakub Kicinski
Following steps are taken in the driver to offload an XDP program: XDP_SETUP_PROG: * prepare: - allocate program state; - run verifier (bpf_analyzer()); - run translation; * load: - stop old program if needed; - load program; - enable BPF if not enabled; * clean up: - free program image. With new infrastructure the flow will look like this: BPF_OFFLOAD_VERIFIER_PREP: - allocate program state; BPF_OFFLOAD_TRANSLATE: - run translation; XDP_SETUP_PROG: - stop old program if needed; - load program; - enable BPF if not enabled; BPF_OFFLOAD_DESTROY: - free program image. Take advantage of the new infrastructure. Allocation of driver metadata has to be moved from jit.c to offload.c since it's now done at a different stage. Since there is no separate driver private data for verification step, move temporary nfp_meta pointer into nfp_prog. We will now use user space context offsets.

2017-11-05bpf: offload: add infrastructure for loading programs for a specific netdevJakub Kicinski
The fact that we don't know which device the program is going to be used on is quite limiting in current eBPF infrastructure. We have to reverse or limit the changes which kernel makes to the loaded bytecode if we want it to be offloaded to a networking device. We also have to invent new APIs for debugging and troubleshooting support. Make it possible to load programs for a specific netdev. This helps us to bring the debug information closer to the core eBPF infrastructure (e.g. we will be able to reuse the verifer log in device JIT). It allows device JITs to perform translation on the original bytecode. __bpf_prog_get() when called to get a reference for an attachment point will now refuse to give it if program has a device assigned. Following patches will add a version of that function which passes the expected netdev in. @type argument in __bpf_prog_get() is renamed to attach_type to make it clearer that it's only set on attachment. All calls to ndo_bpf are protected by rtnl, only verifier callbacks are not. We need a wait queue to make sure netdev doesn't get destroyed while verifier is still running and calling its driver.

Today Open vSwitch users are moving internal ports to other namespaces and although packets are flowing OK, the userspace daemon can't find out basic information like if the port is UP or DOWN, for instance.

2017-11-05rtnetlink: use netnsid to query interfaceJiri Benc
Currently, when an application gets netnsid from the kernel (for example as the result of RTM_GETLINK call on one end of the veth pair), it's not much useful. There's no reliable way to get to the netns fd from the netnsid, nor does any kernel API accept netnsid. Extend the RTM_GETLINK call to also accept netnsid. It will operate on the netns with the given netnsid in such case. Of course, the calling process needs to have enough capabilities in the target name space; for now, require CAP_NET_ADMIN. This can be relaxed in the future. To signal to the calling process that the kernel understood the new IFLA_IF_NETNSID attribute in the query, it will include it in the response. This is needed to detect older kernels, as they will just ignore IFLA_IF_NETNSID and query in the current name space. This patch implemetns IFLA_IF_NETNSID only for get and dump. For set operations, this can be extended later. Signed-off-by: Jiri Benc <jbenc@redhat.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2017-11-05openvswitch: reliable interface indentification in port dumpsJiri Benc
This patch allows reliable identification of netdevice interfaces connected to openvswitch bridges. In particular, user space queries the netdev interfaces belonging to the ports for statistics, up/down state, etc. Datapath dump needs to provide enough information for the user space to be able to do that. Currently, only interface names are returned. This is not sufficient, as openvswitch allows its ports to be in different name spaces and the interface name is valid only in its name space. What is needed and generally used in other netlink APIs, is the pair ifindex+netnsid. The solution is addition of the ifindex+netnsid pair (or only ifindex if in the same name space) to vport get/dump operation. On request side, ideally the ifindex+netnsid pair could be used to get/set/del the corresponding vport. This is not implemented by this patch and can be added later if needed.

2017-11-04net/mlx5e: Enable CQE based moderation on TX CQTal Gilboa
By using CQE based moderation on TX CQ we can reduce the number of TX interrupt rate. Besides the benefit of less interrupts, this also allows the kernel to better utilize TSO. Since TSO has some CPU overhead, it might not aggregate when CPU is under high stress. By reducing the interrupt rate and the CPU utilization, we can get better aggregation and better overall throughput. The feature is enabled by default and has a private flag in ethtool for control.

If the port is in DSCP trust state, packets are placed in the right priority queue based on the dscp value. This is done by selecting the transmit queue based on the dscp of the skb. Until now select_queue honors priority only from the vlan header. However that is not sufficient in cases where port trust state is DSCP mode as packet might not even contain vlan header. Therefore if the port is in dscp trust state and vport's min inline mode is not NONE, copy the IP header to the eseg's inline header if the skb has it. This is done by changing the transmit queue sq's min inline mode to L3. Note that the min inline mode of sqs that belong to other features such as xdpsq, icosq are not modified.

2017-11-04net: sched: cls_u32: use bitwise & rather than logical && on n->flagsColin Ian King
Currently n->flags is being operated on by a logical && operator rather than a bitwise & operator. This looks incorrect as these should be bit flag operations. Fix this.

2017-11-04add support of IFF_XMIT_DST_RELEASE bit in vlanVadim Fedorenko
Some time ago Eric Dumazet suggested a "hack the IFF_XMIT_DST_RELEASE flag on the vlan netdev". But the last comment was "does not support properly bonding/team.(If the real_dev->privflags IFF_XMIT_DST_RELEASE bit changes, we want to update all the vlans at the same time )" I've extended that patch to support changes of IFF_XMIT_DST_RELEASE in bonding/team. Both bonding and team call netdev_change_features() after recalculation of features including priv_flags IFF_XMIT_DST_RELEASE bit. So the only thing needed to support is to recheck this bit in vlan_transfer_features().
