Kirill found that recently added synchronize_rcu() call in ip6mr_sk_done() was slowing down netns dismantle and posted a patch to use it only if the socket was found. I instead suggested to get rid of this call, and use instead SOCK_RCU_FREE We might later change IPv4 side to use the same technique and unify both stacks. IPv4 does not use synchronize_rcu() but has a call_rcu() that could be replaced by SOCK_RCU_FREE.

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: NDavid S. Miller <davem@davemloft.net>

由 Maxime Chevallier 提交于
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.

The mvpp2_prs_mac_da_accept function takes into parameter both the struct representing the controller and the port id. This is meaningful when we want to create TCAM entries for non-initialized ports, but in this case we expect the port to be initialized before starting adding or removing MAC addresses to the per-port filter. This commit changes the function so that it takes struct mvpp2_port as a parameter instead. Signed-off-by: NMaxime Chevallier <maxime.chevallier@bootlin.com> Signed-off-by: NDavid S.

Merge tag 'mlx5-updates-2018-02-28-1' of 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.

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.
