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:

Initializing work-queues every time ifup operation performed is unnecessary and can be performed only once when the port is created. 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:

Some firmware images may reuse CRC32 hardware to compute RXHASH. Make sure we report the correct hash function. Note that we don't support changing functions at runtime. That would also require a few more additions to the way the key is set because different functions have different key sizes. 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:

Thomas Petazzoni says: ==================== net: mvpp2: add initial support for PPv2.2 The goal of this patch series is to add basic support for PPv2.2 in the existing mvpp2 driver. mvpp2 currently supported the PPv2.1 version of the IP, used in the 32 bits Marvell Armada 375 SoC. PPv2.2 is an evolution of this IP block, used in the 64 bits Marvell Armada 7K/8K SoCs. In order to ease the review, the introduction of PPv2.2 support has been made into multiple small commits, with the final commit adding the compatible string that makes the PPv2.2 support actually usable. The series remain fully bisectable. People interested in testing the code will find the full series (plus a few Device Tree patches) at: https://github.com/MISL-EBU-System-SW/mainline-public/tree/4.11/mvpp2.2-support-v3 I'd like to thank Stefan Chulski and Marcin Wojtas, who helped me a lot in the development of this patch series, by reviewing the patches, and giving lots of useful hints to debug the driver on PPv2.2. Thanks as well to Russell King for reviewing previous iterations of this series, and providing suggestions and fixes. Changes between v2 and v3: - Rebased on v4.11-rc1. - Add patch "net: mvpp2: fix DMA address calculation in mvpp2_txq_inc_put()", to properly take into account the "packet offset" field of the TX descriptors. Without this, we were getting DMA_API_DEBUG warnings that we are unmapping DMA mappings with a non-mapped DMA address. - In patch "net: mvpp2: add and use accessors for TX/RX descriptors", add a function named mvpp2_txdesc_offset_get(), which is needed for the DMA address calculation fix. - In patch "net: mvpp2: add and use accessors for TX/RX descriptors", fix the calculation of tx_desc physical address and packet offset in mvpp2_tx_frag_process(). The offset was assigned into the buffer physical address, and the physical address to the packet offset, which meant the fragment process was completely broken. - In patch "net: mvpp2: adjust the allocation/free of BM pools for PPv2.2" fix how MVPP22_BM_ADDR_HIGH_VIRT_RLS_MASK is used. This mask is already shifted. So the value should be shifted before being masked and not the opposite. - Add a new patch "net: mvpp2: set dma mask and coherent dma mask on PPv2.2", to set the DMA mask and DMA coherent mask. By setting the DMA mask to 40 bits we avoid using bounce buffers when network packets are above the 4 GB limit. The coherent mask remains set to 32 bits, because the BM pools must all have the same high 32 bits in their addresses. - Use "dma" instead of "phys" where appropriate, as suggested by Russell King. - Use the "cookie" field of the RX descriptor to store the physical address instead of the virtual address, and then use phys_to_virt() to get the virtual address. This allows to work around the limit that the "cookie" field only has 40 bits, which is not sufficient to store a virtual address on 64 bits platforms. This was suggested by Russell King. As part of this change, also got rid of all the compile time conditionals on CONFIG_ARCH_DMA_ADDR_T_64BIT, to get better compile-time coverage. - In patch "net: mvpp2: handle misc PPv2.1/PPv2.2 differences": * Instead of calling mvpp21_port_power_up(port) only on PPv2.1, remove this function, and call its relevant parts directly from ->probe(). Only mvpp2_port_fc_adv_enable() is PPv2.1 specific. Reported by Russell King. * Add a mvpp22_port_mii_set() function that properly initializes SGMII support on PPv2.2. Code provided by Russell King. - In patch "net: mvpp2: handle register mapping and access for PPv2.2": * Adjust the code to match the change of the DT binding in terms of mapping the second register area on PPv2.2. * Rework the register accessors to remove the get_cpu()/put_cpu(), and instead use separate accessors for global registers vs. per-CPU registers. - Add a few new patches removing dead/unused/useless code: net: mvpp2: remove support for buffer header net: mvpp2: remove unused register definition MVPP2_TXQ_THRESH_REG net: mvpp2: remove mvpp2_txq_pend_desc_num_get() function - Fix a number of checkpatch warnings. Changes between v1 and v2: - Made a separate series from the set of patches doing preparation changes/fixes to the mvpp2 driver. - Rebased on top of v4.10-rc1. - Update Kconfig text of the mvpp2 driver to mention the support for Armada 7K and 8K (PPv2.2). ==================== Signed-off-by:
