The .ndo_get_vf_config() is returning the wrong qos attribute. Fix the code that checks and reports the qos and spoofchk attributes.

Add a new optional conntrack action attribute OVS_CT_ATTR_EVENTMASK, which can be used in conjunction with the commit flag (OVS_CT_ATTR_COMMIT) to set the mask of bits specifying which conntrack events (IPCT_*) should be delivered via the Netfilter netlink multicast groups. Default behavior depends on the system configuration, but typically a lot of events are delivered. This can be very chatty for the NFNLGRP_CONNTRACK_UPDATE group, even if only some types of events are of interest. Netfilter core init_conntrack() adds the event cache extension, so we only need to set the ctmask value. However, if the system is configured without support for events, the setting will be skipped due to extension not being found.

This patch addresses a modification in the PAPR+ specification which now defines a previously reserved value for vNIC capabilities. It indicates whether the system firmware performs a VLAN header stripping on all VLAN tagged received frames, in case it does, the behavior expected is for the ibmvnic driver to be responsible for inserting the VLAN header.

Mike Maloney authored
Fanout uses a per net global namespace. A process that intends to create a new fanout group can accidentally join an existing group. It is not possible to detect this. Add socket option PACKET_FANOUT_FLAG_UNIQUEID. When specified the supplied fanout group id must be set to 0, and the kernel chooses an id that is not already in use. This is an ephemeral flag so that other sockets can be added to this group using setsockopt, but NOT specifying this flag. The current getsockopt(..., PACKET_FANOUT, ...) can be used to retrieve the new group id. We assume that there are not a lot of fanout groups and that this is not a high frequency call. The method assigns ids starting at zero and increases until it finds an unused id. It keeps track of the last assigned id, and uses it as a starting point to find new ids.

Some boards [1] leave the PHYs at an invalid state during system power-up or reset thus causing unreliability issues with the PHY which manifests as PHY not being detected or link not functional. To fix this, these PHYs need to be RESET via a GPIO connected to the PHY's RESET pin. Some boards have a single GPIO controlling the PHY RESET pin of all PHYs on the bus whereas some others have separate GPIOs controlling individual PHY RESETs. In both cases, the RESET de-assertion cannot be done in the PHY driver as the PHY will not probe till its reset is de-asserted. So do the RESET de-assertion in the MDIO bus driver.

Packet capture is an essential feature for network communication. Gerard began addressing this feature gap in his Google Summer of Code 2016 project. I have cleaned up, rebased, and retested the v2 series he posted previously. The design follows the nlmon packet capture interface closely. This is because vsock has the same problem as netlink: there is no netdev on which packets can be captured. The nlmon driver is a synthetic netdev purely for the purpose of enabling packet capture. We follow the same approach here with vsockmon. See include/uapi/linux/vsockmon.h in this series for details on the packet layout. How to try it: 1. Build tcpdump with vsockmon patches: $ git clone -b vsock https://github.com/stefanha/libpcap $ (cd libcap && ./configure && make) $ git clone -b vsock https://github.com/stefanha/tcpdump $ (cd tcpdump && ./configure && make) 2. Build nc-vsock (a netcat-like tool): $ git clone https://github.com/stefanha/nc-vsock $ (cd nc-vsock && make) 3. Launch a virtual machine: # modprobe vhost_vsock # qemu-system-x86_64 -M accel=kvm -m 1024 -cpu host \ -drive if=virtio,file=test.img,format=raw \ -device vhost-vsock-pci,guest-cid=3 (Assumes guest is running a kernel with this patch) 4. Capture AF_VSOCK traffic in guest and/or host: # modprobe vsockmon # ip link add type vsockmon # ip link set vsockmon0 up # tcpdump -i vsockmon0 -vvv 5. Communicate! (host)$ nc-vsock -l 1234 (guest)$ nc-vsock 2 1234 ==================== Signed-off-by: David S. Miller <davem@davemloft.net>

The virtio drivers deal with struct virtio_vsock_pkt. Add virtio_transport_deliver_tap_pkt(pkt) for handing packets to the vsockmon device. We call virtio_transport_deliver_tap_pkt(pkt) from net/vmw_vsock/virtio_transport.c and drivers/vhost/vsock.c instead of common code. This is because the drivers may drop packets before handing them to common code - we still want to capture them.

Bernd Faust fixes an issue for 82579 devices, where the clock frequency was being incorrectly set for these devices. These devices only support 96MHz, so make sure they are set to use only that. Yury Kylulin extends the work Jake and Alex did for ixgbe in MAC filter handling into the igb driver.
