2017-04-24ibmvnic: Add set_link_state routine for setting adapter link stateNathan Fontenot
Create a common routine for setting the link state for the vnic adapter. This update moves the sending of the crq and waiting for the link state response to a common place. The new routine also adds handling of resending the crq in cases of getting a partial success response. Signed-off-by: Nathan Fontenot <nfont@linux.vnet.ibm.com> Signed-off-by: David S.

2017-04-24ibmvnic: Insert header on VLAN tagged received frameMurilo Fossa Vicentini
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.

2017-04-24ipv4: Avoid caching l3mdev dst on mismatched local routeRobert Shearman
David reported that doing the following: ip li add red type vrf table 10 ip link set dev eth1 vrf red ip addr add 127.0.0.1/8 dev red ip link set dev eth1 up ip li set red up ping -c1 -w1 -I red 127.0.0.1 ip li del red when either policy routing IP rules are present or the local table lookup ip rule is before the l3mdev lookup results in a hang with these messages: unregister_netdevice: waiting for red to become free. Usage count = 1 The problem is caused by caching the dst used for sending the packet out of the specified interface on a local route with a different nexthop interface. Thus the dst could stay around until the route in the table the lookup was done is deleted which may be never. Address the problem by not forcing output device to be the l3mdev in the flow's output interface if the lookup didn't use the l3mdev. This then results in the dst using the right device according to the route. Changes in v2: - make the dev_out passed in by __ip_route_output_key_hash correct instead of checking the nh dev if FLOWI_FLAG_SKIP_NH_OIF is set as suggested by David.

2017-04-24packet: add PACKET_FANOUT_FLAG_UNIQUEID to assign new fanout group id.Mike Maloney
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.

2017-04-24mdio_bus: Issue GPIO RESET to PHYs.Roger Quadros
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!

2017-04-24VSOCK: Add virtio vsock vsockmon hooksGerard Garcia
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.

2017-04-24net/mlx5e: Fix race in mlx5e_sw_stats and mlx5e_vport_statsMartin KaFai Lau
We have observed a sudden spike in rx/tx_packets and rx/tx_bytes reported under /proc/net/dev. There is a race in mlx5e_update_stats() and some of the get-stats functions (the one that we hit is the mlx5e_get_stats() which is called by ndo_get_stats64()). In particular, the very first thing mlx5e_update_sw_counters() does is 'memset(s, 0, sizeof(*s))'. For example, if mlx5e_get_stats() is unlucky at one point, rx_bytes and rx_packets could be 0. One second later, a normal (and much bigger than 0) value will be reported. This patch is to use a 'struct mlx5e_sw_stats temp' to avoid a direct memset zero on priv->stats.sw. mlx5e_update_vport_counters() has a similar race. Hence, addressed together. However, memset zero is removed instead because it is not needed. I am lucky enough to catch this 0-reset in rx multicast: eth0: 41457665 76804 70 0 0 70 0 47085 15586634 87502 3 0 0 0 3 0 eth0: 41459860 76815 70 0 0 70 0 47094 15588376 87516 3 0 0 0 3 0 eth0: 41460577 76822 70 0 0 70 0 0 15589083 87521 3 0 0 0 3 0 eth0: 41463293 76838 70 0 0 70 0 47108 15595872 87538 3 0 0 0 3 0 eth0: 41463379 76839 70 0 0 70 0 47116 15596138 87539 3 0 0 0 3 0 v2: Remove memset zero from mlx5e_update_vport_counters() v1: Use temp and memcpy Fixes: 9218b44dcc05 ("net/mlx5e: Statistics handling refactoring") Suggested-by: Eric Dumazet <eric.dumazet@gmail.com> Suggested-by: Saeed Mahameed <saeedm@mellanox.com> Signed-off-by: Martin KaFai Lau <kafai@fb.com> Acked-by: Saeed Mahameed <saeedm@mellanox.com> Signed-off-by: David S.

2017-04-24crypto: algif_aead - Require setkey before accept(2)Stephan Mueller
Some cipher implementations will crash if you try to use them without calling setkey first. This patch adds a check so that the accept(2) call will fail with -ENOKEY if setkey hasn't been done on the socket yet.

2017-04-24crypto: ccp - Change ISR handler method for a v5 CCPGary R Hook
The CCP has the ability to perform several operations simultaneously, but only one interrupt. When implemented as a PCI device and using MSI-X/MSI interrupts, use a tasklet model to service interrupts. By disabling and enabling interrupts from the CCP, coupled with the queuing that tasklets provide, we can ensure that all events (occurring on the device) are recognized and serviced. This change fixes a problem wherein 2 or more busy queues can cause notification bits to change state while a (CCP) interrupt is being serviced, but after the queue state has been evaluated. This results in the event being 'lost' and the queue hanging, waiting to be serviced. Since the status bits are never fully de-asserted, the CCP never generates another interrupt (all bits zero -> one or more bits one), and no further CCP operations will be executed.
