Jiri Pirko says: ==================== ipv4: fib: FIB notifications cleanup Ido says: The first patch moves the core FIB notification code to a separate file, so that code related to FIB rules is placed in fib_rules.c and not fib_trie.c. The reason for the change will become even more apparent in follow-up patchset where we extend the FIB rules notifications. Second patch removes a redundant argument. ==================== Signed-off-by: -

We always pass the same event type to fib_notify() and fib_rules_notify(), so we can safely drop this argument. Signed-off-by:

Most of the code concerned with the FIB notification chain currently resides in fib_trie.c, but this isn't really appropriate, as the FIB notification chain is also used for FIB rules. Therefore, it makes sense to move the common FIB notification code to a separate file and have it export the relevant functions, which can be invoked by its different users (e.g., fib_trie.c, fib_rules.c).

Jiri Pirko says: ==================== mlxsw: Preparations for VRF offload Ido says: This patchset aims to prepare the mlxsw driver for VRF offload. The follow-up patchsets that introduce VRF support can be found here: https://github.com/idosch/linux/tree/idosch-next The first four patches are mainly concerned with the netdevice notification block. There are no functional changes, but merely restructuring to more easily integrate VRF enslavement. Patches 5-10 remove various assumptions throughout the code about a single virtual router (VR) and also restructure the internal data structures to more accurately represent the device's operation. ==================== Signed-off-by:

When the abort mechanism is invoked it binds the first virtual router (VR) to an LPM tree and inserts a default route to direct packets to the CPU. With VRFs, we can have router interfaces (RIFs) bound to multiple VRs, so we need to make sure packets are trapped from all VRs and not just the first one. Upon abort invocation, bind all active VRs to the same LPM tree and insert a default route in each. Signed-off-by:

Up until now we implicitly associated all the router interfaces (RIFs) with the first virtual router (VR). This must be changed in order to enable VRF offload. Otherwise, a packet received via a VRF slave would do a FIB lookup in the same table used by other VRFs. Instead, bind the RIF to a VR according to the table where FIB lookup should be performed for packets received via the RIF. Currently, we only care about the MAIN and LOCAL tables (which we squash together). Signed-off-by:

A virtual router (VR) is an entity within the device to which routing tables and interfaces can be bound to. It can be used to implement VRFs. In the initial implementation we associated the VR with a specific protocol (e.g., IPv4) and an LPM tree. However, this isn't really accurate, as the same VR can be used for both IPv4 and IPv6 traffic, by binding a different LPM tree to a {VR, Proto} pair. This patch aims to restructure the VR code according to the above logic, so that VRs are more accurately represented by the driver's data structures. The main motivation behind this change is to prepare the driver for VRF offload. Signed-off-by: -

When looking for a new LPM tree we should always consider all the unused trees. It doesn't matter if the new tree is required due to changes in currently used prefixes inside an existing routing table or because a route was inserted into an empty table. Both cases are functionally identical and therefore should be treated the same. When looking for a new LPM tree, consider all unused trees and don't reserve trees for specific cases. Signed-off-by:

The inetaddr notification block is currently implemented in the main driver file, but this isn't really appropriate, as it mainly creates and destroys router interfaces (RIFs) which belong with the rest of the router code. This will become even more apparent later on when we'll need to bind these RIFs to virtual routers according to the VRF's table. Structure the driver better and prevent unnecessary function exports by moving the RIF related code with the rest of the router code. Signed-off-by:

Allow 'unreachable', 'blackhole' and 'prohibit' route types to be programmed into the device by sending any packet hitting them to the CPU. This is needed so that users will be able to program a default route into the VRF's table, thereby preventing lookup from leaking to other tables. Audit the code paths to make sure we don't rely on the presence of a nexthop netdev, as it doesn't exist for above mentioned route types. Signed-off-by:

We only use the RIF reference count to determine when the last IP address was removed, but instead we can just test 'in_dev->ifa_list'. Signed-off-by:

When a VLAN device is configured on top of a LAG device (f.e., bond0.10), a vPort is created on top of each of the LAG's slaves and its 'dev' pointer is set to the VLAN device. This is in contrast to the implicit PVID vPort (representing 'bond0'), whose 'dev' pointer keeps pointing to the port netdev itself (f.e., 'sw1p1'). Make both cases consistent by setting their 'dev' pointer to the actual netdev they represent. Either the LAG device itself (in the case of the PVID vPort) or the VLAN device on top of it. This will later allow us to more easily understand for which netdev we should create the router interface (RIF) upon enslavement to a VRF master. Signed-off-by:

When an upper device is configured on top of a vPort we make sure it's a bridge master during PRECHANGEUPPER and fail otherwise. Therefore, when CHANGEUPPER is later received we don't bother checking the upper's type. Make the code more extendable in preparation for VRF uppers, by checking the upper's type. Signed-off-by:

We're going to allow bridges stacked on top of port netdevs to be enslaved to a VRF, but for now, only VLAN uppers of the VLAN-aware bridge are supported. Sanitize any other bridge upper. This is consistent with the way we sanitize port netdevs' uppers. Signed-off-by:

In original driver was implemented support for half- and full-duplex modes, but it was not enabled. Instead of it ks8851_rx_1msg method always returns "true" that means "full-duplex" mode. This patch replaces hard-coded functionality with flexible solution that supports both SPI modes. Signed-off-by:

Mahesh Bandewar says: ==================== bonding: winter cleanup Few cleanup patches that I have accumulated over some time now. (a) First two patches are basically to move the work-queue initialization from every ndo_open / bond_open operation to once at the beginning while port creation. Work-queue initialization is an unnecessary operation for every 'ifup' operation. However we have some mode-specific work-queues and mode can change anytime after port creation. So the second patch is to ensure the correct work-handler is called based on the mode. (b) Third patch is simple and straightforward that removes hard-coded value that was added into the initial commit and replaces it with the default value configured. (c) The final patch in the series removes the unimplemented "port-moved" state from the LACP state machine. This state is defined but never set so removing from the state machine logic makes code little cleaner. (d) Reduce scope of some global variables to local. Note: None of these patches are making any functional changes. ==================== Signed-off-by: -

LACP state-machine defines "port-moved" state when the same ActorSystemID and Port are seen in a LACPDU received on different port. The state is never set since it's not implemented. However the state-machine attempts to clear that state occasionally. LACP state machine is already complicated and since this state is not implemented, removing it's checks makes the state-machine little simpler. Signed-off-by:

Mahesh Bandewar authored
In preparation to move the work-queue initialization to port creation from current port_open phase. Work-queue initialization does not make sense every time we do 'ifup/ifdown'. So moving to port creation phase. Arp monitoring work depends on the bonding mode and that is not tied to the port creation and can change anytime during the life after port creation. So this restructuring allows us to move the initialization at creation without losing the ability to arm the correct work for the mode user has selected. Signed-off-by:

Jakub Kicinski says: ==================== nfp: CRC32 RSS hash, port name reporting and misc fastpath cleanups This series adds support for CRC32 RSS hash function to kernel API of which NFP driver immediately makes use. There is also a .ndo_get_phys_port_name() implementation conforming to switchdev name format. Small patch takes advantage of napi_complete_done()'s return code. Simon provides a fix for potentially trusting values returned from FW too much. A handful of unassuming fast path adjustments is also thrown in to make the upcoming xdp_adjust_head() series easier to review. ==================== Signed-off-by: -

NSP reports to us port labels. First id is the id of the physical port, the other one tells us which logical interface is it within a split port. Instead of printing them as string keep them in integer format. Compute which interfaces are part of port split. On netdev side use port labels and split information to provide a .ndo_get_phys_port_name() implementation. We follow the name format of mlxsw which is also suggested in "Port Netdev Naming" section of Documentation/networking/switchdev.txt. Signed-off-by:

Currently the sock queue's spin locks get their lockdep classes by the default init_spin_lock() initializer: all socket families get - usually, see below - a single class for rx, another specific class for tx, etc. This can lead to false positive lockdep splat, as reported by Andrey. Moreover there are two separate initialization points for the sock queues, one in sk_clone_lock() and one in sock_init_data(), so that e.g. the rx queue lock can get one of two possible, different classes, depending on the socket being cloned or not. This change tries to address the above, setting explicitly a per address family lockdep class for each queue's spinlock. Also, move the duplicated initialization code to a single location. v1 -> v2: - renamed the init helper rfc -> v1: - no changes, tested with several different workload Suggested-by:
