2018-03-08net: Convert nfnetlink_net_opsKirill Tkhai
These pernet_operations create and destroy net::nfnl socket of NETLINK_NETFILTER code. There are no other places, where such type the socket is created, except these pernet_operations. It seem other pernet_operations depending on CONFIG_NETFILTER_NETLINK send messages to this socket. So, we mark it async. Signed-off-by: Kirill Tkhai <ktkhai@virtuozzo.com> Signed-off-by: David S.

These pernet_operations create and destroy net::xfrm::nlsk socket of NETLINK_XFRM. There is only entry point, where it's dereferenced, it's xfrm_user_rcv_msg(). There is no in-kernel senders to this socket. Signed-off-by: Kirill Tkhai <ktkhai@virtuozzo.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2018-03-08net: Convert ip6 tables pernet_operationsKirill Tkhai
The pernet_operations: ip6table_filter_net_ops ip6table_mangle_net_ops ip6table_nat_net_ops ip6table_raw_net_ops ip6table_security_net_ops have exit methods, which call ip6t_unregister_table(). ip6table_filter_net_ops has init method registering filter table. Since there must not be in-flight ipv6 packets at the time of pernet_operations execution and since pernet_operations don't send ipv6 packets each other, these pernet_operations are safe to be async.

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>

The current code has one layer that executed FPGA commands and the Ethernet part directly used this code. Since downstream patches introduces support for IPSec in mlx5_ib, we need to provide some abstractions. 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.

2018-03-07net/mlx5e: IPSec, Add support for ESP trailer removal by hardwareYossi Kuperman
Current hardware decrypts and authenticates incoming ESP packets. Subsequently, the software extracts the nexthdr field, truncates the trailer and adjusts csum accordingly. With this patch and a capable device, the trailer is being removed by the hardware and the nexthdr field is conveyed via PET. This way we avoid both the need to access the trailer (cache miss) and to compute its relative checksum, which significantly improve the performance. Experiment shows that trailer removal improves the performance by 2Gbps, (netperf). Both forwarding and host-to-host configurations.

Maxime Chevallier says: ==================== net: mvpp2: Add Unicast filtering capabilities This series adds unicast filtering support to the Marvell PPv2 controller. This is implemented using the header parser cababilities of the PPv2, which allows for generic packet filtering based on matching patterns in the packet headers. PPv2 controller only has 256 of these entries, and we need to share them with other features, such as VLAN filtering. For each interface, we have 5 entries dedicated to unicast filtering (the controller's own address, and 4 other), and 21 to multicast filtering. When this number is reached, the controller switches to unicast or multicast promiscuous mode. The first patch reworks the function that adds and removes addresses to the filter. This is preparatory work to ease UC filter implementation. The second patch adds the UC filtering feature. ==================== Signed-off-by: David S. Miller <davem@davemloft.net>
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.

git://git.kernel.org/pub/scm/linux/kernel/git/mellanox/linux Saeed Mahameed says: ==================== mlx5-updates-2018-02-28-1 (IPSec-1) This series consists of some fixes and refactors for the mlx5 drivers, especially around the FPGA and flow steering. 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.

One single test implemented so far: test_pmtu_vti6_exception checks that the PMTU of a route exception, caused by a tunnel exceeding the link layer MTU, is affected by administrative changes of the tunnel MTU. Creation of the route exception is checked too.

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.

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.

2018-03-07Merge branch 'net-phy-remove-phy_error-from-phy_disable_interrupts'David S. Miller
Heiner Kallweit says: ==================== net: phy: remove phy_error from phy_disable_interrupts 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() takes this lock). Make use of this in phy_stop(). v2: - splitted into two separate patches ==================== Signed-off-by: David S. Miller <davem@davemloft.net>
