2017-03-22net: vrf: Reset rt6i_idev in local dst after putDavid Ahern1-1/+3
The VRF driver takes a reference to the inet6_dev on the VRF device for its rt6_local dst when handling local traffic through the VRF device as a loopback. When the device is deleted the driver does a put on the idev but does not reset rt6i_idev in the rt6_info struct. When the dst is destroyed, dst_destroy calls ip6_dst_destroy which does a second put for what is essentially the same reference causing it to be prematurely freed. Reset rt6i_idev after the put in the vrf driver.

When the aquantia device mtu is changed the net_device structure is not updated. As a result the ip command does not properly reflect the mtu change.

2017-03-17net/mlx4_core: Avoid delays during VF driver device shutdownJack Morgenstein2-0/+22
Some Hypervisors detach VFs from VMs by instantly causing an FLR event to be generated for a VF. In the mlx4 case, this will cause that VF's comm channel to be disabled before the VM has an opportunity to invoke the VF device's "shutdown" method. For such Hypervisors, there is a race condition between the VF's shutdown method and its internal-error detection/reset thread. The internal-error detection/reset thread (which runs every 5 seconds) also detects a disabled comm channel. If the internal-error detection/reset flow wins the race, we still get delays (while that flow tries repeatedly to detect comm-channel recovery). The cited commit fixed the command timeout problem when the internal-error detection/reset flow loses the race. This commit avoids the unneeded delays when the internal-error detection/reset flow wins.

2017-03-16amd-xgbe: Fix jumbo MTU processing on newer hardwareLendacky, Thomas3-50/+78
Newer hardware does not provide a cumulative payload length when multiple descriptors are needed to handle the data. Once the MTU increases beyond the size that can be handled by a single descriptor, the SKB does not get built properly by the driver. The driver will now calculate the size of the data buffers used by the hardware. The first buffer of the first descriptor is for packet headers or packet headers and data when the headers can't be split. Subsequent descriptors in a multi-descriptor chain will not use the first buffer. The second buffer is used by all the descriptors in the chain for payload data. Based on whether the driver is processing the first, intermediate, or last descriptor it can calculate the buffer usage and build the SKB properly. Tested and verified on both old and new hardware.

2017-03-14qed: Fix interrupt flags on Rx LL2Ram Amrani1-4/+5
Before iterating over the the LL2 Rx ring, the ring's spinlock is taken via spin_lock_irqsave(). The actual processing of the packet [including handling by the protocol driver] is done without said lock, so qed releases the spinlock and re-claims it afterwards. Problem is that the final spin_lock_irqrestore() at the end of the iteration uses the original flags saved from the initial irqsave() instead of the flags from the most recent irqsave(). So it's possible that the interrupt status would be incorrect at the end of the processing.

2017-03-14tun: fix premature POLLOUT notification on tun devicesHannes Frederic Sowa1-3/+15
aszlig observed failing ssh tunnels (-w) during initialization since commit cc9da6cc4f56e0 ("ipv6: addrconf: use stable address generator for ARPHRD_NONE"). We already had reports that the mentioned commit breaks Juniper VPN connections. I can't clearly say that the Juniper VPN client has the same problem, but it is worth a try to hint to this patch. Because of the early generation of link local addresses, the kernel now can start asking for routers on the local subnet much earlier than usual. Those router solicitation packets arrive inside the ssh channels and should be transmitted to the tun fd before the configuration scripts might have upped the interface and made it ready for transmission. ssh polls on the interface and receives back a POLL_OUT. It tries to send the earily router solicitation packet to the tun interface. Unfortunately it hasn't been up'ed yet by config scripts, thus failing with -EIO. ssh doesn't retry again and considers the tun interface broken forever.

When a network interface controlled by the aquantia ethernet driver is brought down a warning is output in dmesg (see below). The problem is that aq_pci_func_free_irqs() is calling free_irq() before it is calling irq_set_affinity_hint().

2017-03-10net/mlx5e: Fix loopback selftestEugenia Emantayev1-4/+1
Change packet type handler to ETH_P_IP instead of ETH_P_ALL since we are already expecting an IP packet. Also, using ETH_P_ALL will cause the loopback test packet type handler to be called on all outgoing packets, especially our own self loopback test SKB, which will be validated on xmit as well, and we don't want that. Tested with: ethtool -t ethX validated that the loopback test passes.

2017-03-10net/mlx5e: Avoid wrong identification of rules on deletionOr Gerlitz1-15/+18
When deleting offloaded TC flows, we must correctly identify E-switch rules. The current check could get us wrong w.r.t to rules set on the PF. Since it's possible to set NIC rules on the PF, switch to SRIOV offloads mode and then attempt to delete a NIC rule. To solve that, we add a flags field to offloaded rules, set it on creation time and use that over the code where currently needed.

2017-03-10net/mlx5: Fix create autogroup prev initializerPaul Blakey1-1/+1
The autogroups list is a list of non overlapping group boundaries sorted by their start index. If the autogroups list wasn't empty and an empty group slot was found at the start of the list, the new group was added to the end of the list instead of the beginning, as the prev initializer was incorrect. When this was repeated, it caused multiple groups to have overlapping boundaries. Fixed that by correctly initializing the prev pointer to the start of the list.
