2018-03-09net: hns3: refactor the coalesce related structYunsheng Lin

2018-03-09net: hns3: fix for coalesce configuration lost during resetYunsheng Lin
Coalesce configuration will be set to default value by hns3_nic_init_vector_data during reset, which causes the coalesce configuration loss problem. This patch fixes it by setting the default value in hns3_nic_alloc_vector_data, which will not be called in the reset process.

2018-03-09net: hns3: fix for use-after-free when setting ring parameterYunsheng Lin
In hns3_set_ringparam, hns3_uninit_all_ring frees the memory pointed by priv->ring_data[i].ring, and hns3_change_all_ring_bd_num use that pointer without mallocing, which will cause a use-after-free problem.

git://git.kernel.org/pub/scm/linux/kernel/git/mellanox/linux Saeed Mahameed says: ==================== mlx5-updates-2018-02-28-2 (IPSec-2) This series follows our previous one to lay out the foundations for IPSec in user-space and extend current kernel netdev IPSec support. As noted in our previous pull request cover letter "mlx5-updates-2018-02-28-1 (IPSec-1)", the IPSec mechanism will be supported through our flow steering mechanism. Therefore, we need to change the initialization order. Furthermore, IPsec is also supported in both egress and ingress. Since our current flow steering is egress only, we add an empty (only implemented through FPGA steering ops) egress namespace to handle that case. We also implement the required flow steering callbacks and logic in our FPGA driver. We extend the FPGA support for ESN and modifying a xfrm too. Therefore, we add support for some new FPGA command interface that supports them. The other required bits are added too. The new features and requirements are advertised via cap bits. Last but not least, we revise our driver's accel_esp API. This API will be shared between our netdev and IB driver, so we need to have all the required functionality from both worlds.

2018-03-08ibmvnic: Do not disable device during failover or partition migrationThomas Falcon
During a device failover or partition migration reset, it is not necessary to disable the backing adapter since it should not be running yet and its Command-Response Queue is closed. Sending device commands during this time could result in an error or timeout disrupting the reset process. In these cases, just halt transmissions, clean up resources, and continue with reset.

2018-03-07net/mlx5: Add flow-steering commands for FPGA IPSec implementationAviad Yehezkel
In order to add a context to the FPGA, we need to get both the software transform context (which includes the keys, etc) and the source/destination IPs (which are included in the steering rule). Therefore, we register new set of firmware like commands for the FPGA. Each time a rule is added, the steering core infrastructure calls the FPGA command layer. If the rule is intended for the FPGA, it combines the IPs information with the software transformation context and creates the respective hardware transform. Afterwards, it calls the standard steering command layer. Signed-off-by: Aviad Yehezkel <aviadye@mellanox.com> Signed-off-by: Saeed Mahameed <saeedm@mellanox.com>

This patch refactors the accel code into one layer that creates a software IPSec transformation and another one which creates the actual hardware context. The internal command implementation is now hidden in the FPGA core layer. The code also adds the ability to share FPGA hardware contexts.

With this patch and a capable device, the trailer is being removed by the hardware and the nexthdr field is conveyed via PET.

2018-03-07net: mvpp2: Add support for unicast filteringMaxime Chevallier
Marvell PPv2 controller can be used to implement packet filtering based on the destination MAC address. This is already used to implement multicast filtering. This patch adds support for Unicast filtering. Filtering is based on so-called "TCAM entries" to implement filtering. Due to their limited number and the fact that these are also used for other purposes, we reserve 80 entries for both unicast and multicast filters. On top of the broadcast address, and each interface's own MAC address, we reserve 25 entries per port, 4 for unicast filters, 21 for multicast. Whenever unicast or multicast range for one port is full, the filtering is disabled and port goes into promiscuous mode for the given type of addresses.

Most of them are trivial fixes and are the foundation of allowing IPSec acceleration from user-space. We use flow steering abstraction in order to accelerate IPSec packets. When a user creates a steering rule, [s]he states that we'll carry an encrypt/decrypt flow action (using a specific configuration) for every packet which conforms to a certain match. Since currently offloading these packets is done via FPGA, we'll add another set of flow steering ops. These ops will execute the required FPGA commands and then call the standard steering ops. In order to achieve this, we need that the commands will get all the required information. Therefore, we pass the fte object and embed the flow_action struct inside the fte. In addition, we add the shim layer that will later be used for alternating between the standard and the FPGA steering commands. Some fixes, like " net/mlx5e: Wait for FPGA command responses with a timeout" are very relevant for user-space applications, as these applications could be killed, but we still want to wait for the FPGA and update the kernel's database.

2018-03-07net/mlx4_en: try to use high order pages for RX ringsEric Dumazet
RX rings can fit most of the time in a contiguous piece of memory, so lets use kvzalloc_node/kvfree instead of vzalloc_node/vfree Note that kvzalloc_node() automatically falls back to another node, there is no need to do the fallback ourselves.

If we fail to register the mdio bus due to probe defer, we should not print an error message. Just be silent in this case. Signed-off-by: Jerome Brunet <jbrunet@baylibre.com> Reviewed-by: Andrew Lunn <andrew@lunn.ch> Signed-off-by: David S. Miller <davem@davemloft.net>
2018-03-07net: unpollute priv_flags spacePaolo Abeni
the ipvlan device driver defines and uses 2 bits inside the priv_flags net_device field. Such bits and the related helper are used only inside the ipvlan device driver, and the core networking does not need to be aware of them. This change moves netif_is_ipvlan* helper in the ipvlan driver and re-implement them looking for ipvlan specific symbols instead of using priv_flags. Overall this frees two bits inside priv_flags - and move the following ones to avoid gaps - without any intended functional change.

Now that phy_disable_interrupts() can't take lock phydev->lock any longer, we can use it to simplify phy_stop(). Signed-off-by: Heiner Kallweit <hkallweit1@gmail.com> Reviewed-by: Andrew Lunn <andrew@lunn.ch> Signed-off-by: David S. Miller <davem@davemloft.net>
2018-03-07net: phy: remove phy_error from phy_disable_interruptsHeiner Kallweit
All callers of phy_disable_interrupts() call phy_error() in the error case. Therefore we don't need to do this within the function too. This change also allows us to use phy_disable_interrupts() in code holding phydev->lock (because phy_error() can take this lock).
