Pablo Neira Ayuso says: ==================== Netfilter updates for net-next The following patchset contains Netfilter updates for net-next to extend ctnetlink and the flowtable infrastructure: 1) Extend ctnetlink kernel side netlink dump filtering capabilities, from Romain Bellan. 2) Generalise the flowtable hook parser to take a hook list. 3) Pass a hook list to the flowtable hook registration/unregistration. 4) Add a helper function to release the flowtable hook list. 5) Update the flowtable event notifier to pass a flowtable hook list. 6) Allow users to add new devices to an existing flowtables. 7) Allow users to remove devices to an existing flowtables. 8) Allow for registering a flowtable with no initial devices. ==================== Signed-off-by: David S.

2020-06-01net: remove indirect block netdev event registrationPablo Neira Ayuso
Drivers do not register to netdev events to set up indirect blocks anymore. Remove __flow_indr_block_cb_register() and __flow_indr_block_cb_unregister().

2020-06-01net: flow_offload: consolidate indirect flow_block infrastructurePablo Neira Ayuso
Tunnel devices provide no dev->netdev_ops->ndo_setup_tc(...) interface. The tunnel device and route control plane does not provide an obvious way to relate tunnel and physical devices. This patch allows drivers to register a tunnel device offload handler for the tc and netfilter frontends through flow_indr_dev_register() and flow_indr_dev_unregister(). The frontend calls flow_indr_dev_setup_offload() that iterates over the list of drivers that are offering tunnel device hardware offload support and it sets up the flow block for this tunnel device. If the driver module is removed, the indirect flow_block ends up with a stale callback reference. The module removal path triggers the dev_shutdown() path to remove the qdisc and the flow_blocks for the physical devices. However, this is not useful for tunnel devices, where relation between the physical and the tunnel device is not explicit. This patch introduces a cleanup callback that is invoked when the driver module is removed to clean up the tunnel device flow_block. This patch defines struct flow_block_indr and it uses it from flow_block_cb to store the information that front-end requires to perform the flow_block_cb cleanup on module removal.

xdp_umem.c had overlapping changes between the 64-bit math fix for the calculation of npgs and the removal of the zerocopy memory type which got rid of the chunk_size_nohdr member. The mlx5 Kconfig conflict is a case where we just take the net-next copy of the Kconfig entry dependency as it takes on the ESWITCH dependency by one level of indirection which is what the 'net' conflicting change is trying to ensure.

2020-05-27net/tls: Add force_resync for driver resyncTariq Toukan
This patch adds a field to the tls rx offload context which enables drivers to force a send_resync call. This field can be used by drivers to request a resync at the next possible tls record. It is beneficial for hardware that provides the resync sequence number asynchronously. In such cases, the packet that triggered the resync does not contain the information required for a resync. Instead, the driver requests resync for all the following TLS record until the asynchronous notification with the resync request TCP sequence arrives. A following series for mlx5e ConnectX-6DX TLS RX offload support will use this mechanism.
