Add test cases for unknown unicast and unregistered multicast flooding. For each traffic type, turn off flooding on one bridged port and inject a packet of the specified type through the second bridged port. Make sure the packet was not received by checking the ACL counters on the other end. Later, turn on flooding and make sure the packet was received. Signed-off-by:

This changeset moves ipvlan address under RCU protection, using a per ipvlan device spinlock to protect list mutation and RCU read access to protect list traversal. Also explicitly use RCU read lock to traverse the per port ipvlans list, so that we can now perform a full address lookup without asserting the RTNL lock. Overall this allows the ipvlan driver to check fully for duplicate addresses - before this commit ipv6 addresses assigned by autoconf via prefix delegation where accepted without any check - and avoid the following rntl assertion failure still in the same code path: RTNL: assertion failed at drivers/net/ipvlan/ipvlan_core.c (124) WARNING: CPU: 15 PID: 0 at drivers/net/ipvlan/ipvlan_core.c:124 ipvlan_addr_busy+0x97/0xa0 [ipvlan] Modules linked in: ipvlan(E) ixgbe CPU: 15 PID: 0 Comm: swapper/15 Tainted: G E 4.16.0-rc2.ipvlan+ #1782 Hardware name: Dell Inc.

Jiri Pirko says: ==================== mlxsw: Offload multi-queue RED support Nogah says: Support a two level hierarchy of offloaded qdiscs in mlxsw, with sch_prio being the root qdisc and sch_red as the children. +----------+ | sch_prio | +----+-----+ | | +----------------------------------+ | | | | | | | | | +---v---+ +----v---+ +-----v--+ |sch_red| |sch_red | |sch_red | +-------+ +--------+ +--------+ When setting sch_prio as the root qdisc on a physical port, mlxsw will offload it. When adding it with sch_red as a child qdisc, it will offload it as well. Relocating child qdisc or connecting them to more then one child will result in unoffloading them. Relocating child qdisc more then once is highly unrecommended and might cause a miss match between the kernel configuration and the offloaded one. The offloaded configuration will be aligned with the one shown in the show command. Changing the priomap parameter of sch_prio might cause a band that its configuration was changed and it has offloaded sch_red set on it, to lose some stats data as if sch_red was unoffloaded and offloaded again. However, it won't affect the data on this band that will have sch_red continuously. Patch 1 adds support for setting RED as the child of root qdisc. Patches 2-4 add support for RED bstasts for offloaded child qdiscs. Patches 5-6 handle backlog related changes for offloaded child qdiscs. Patches 7-8 update PRIO in mlxsw to be able to have RED as child on its bands. Patch 9 adds offload handles for PRIO graft operations. In mlxsw it will cause the driver to stop offloading the child in question. ==================== Signed-off-by: -

Offload sch_prio graft command for capable drivers. Warn in case of a failure, unless the graft was done as part of a destroy operation (the new qdisc is a noop) or if all the qdiscs (the parent, the old child, and the new one) are not offloaded. Signed-off-by:

When the number the bands of sch_prio is decreased, child qdiscs on the deleted bands would get deleted as well. This change and deletions are being done under sch_tree_lock of the sch_prio qdisc. Part of the destruction of qdisc is unoffloading it, if it is offloaded. Un-offloading can't be done inside this lock. Move the offload command to be done before reducing the number of bands, so unoffloading of the qdiscs that are about to be deleted could be done outside of the lock. Signed-off-by:

sch_prio as root qdisc should count all the drops its children have. Since it is possible for it to have sch_red children, it needs to count RED early drops. Signed-off-by:

Offloaded qdiscs are allowed to expose only parts of their statistics. It means that if backlog is being exposed and qlen is not, it might trigger a warning in qdisc_tree_reduce_backlog. Do not warn in case the qdisc that was removed was an offloaded one. Signed-off-by:

Nogah Frankel authored
When removing a child qdisc its backlog will be decreased from the parent backlog. The driver backlog count should do the same. When the parent changes its configuration, the child might need to clean its stats. However, the backlog can't be cleaned with the rest of the stats, because it reflects a momentary value that needs to be synced with the core, not the history of the qdisc. Signed-off-by:

Priority counters count packets according to their packet priority. Collect the stats for sch_red based on these counters, so the qdisc bstats will be the sum of counters matching the priorities marked in the qdisc priomap. Changing the mapping of the priorities to bands while traffic is running can result in losing the stats of the bands qdiscs from their last dump call to this change, as if the qdisc was unoffloaded and re-offloaded. It will not affect the traffic behaviour according to sch_red. Signed-off-by:

Add the option to set a qdisc per tclass. Match the qdisc to the tclass by parent ID. Supported currently for sch_red only. It allows offloading sch_prio as root qdisc and sch_red as its child. (However, doing so might corrupt the stats for both parent and child.) Signed-off-by:

Marvell PPv2 controller allows for generic packet filtering. This commit adds entries to implement VLAN filtering. The approach taken is : - Filter entries that would match on the presence of the VLAN tag (existing VLAN detection, DSA / EDSA detection) will set the next lookup ID to be for the VID. - For each VLAN existing on a given port, we add an entry that matches this specific VID. If the incoming packet matches the VID entry, it is set for the next lookup in the chain (LU_L2). - A Guard entry is added for each port, that will match if the incoming packet didn't match any of the above VID entries. This entry tags the packet to be dropped. Due to this design, and the fact that the total 256 filter entries are also used for other purposes, we have a limit of 10 VLANs per port. To accommodate the case where we would need more VLANS on one port, this patch implements the ndo_set_features to allow for disabling of VLAN filtering using ethtool. The default config has VLAN filtering disabled. Signed-off-by:

Russell King says: ==================== SFP updates Included in this series are a further few updates for SFP support: - Adding support for Fiberstore's non-standard BiDi modules operating at 1310nm/1550nm wavelengths rather than the 1000BASE-BX standard of 1310nm/1490nm. - Adding support for negotiating the PHY interface mode with the MAC, so that modules supporting faster speeds and Gigabit ethernet work with Gigabit-only MACs. - Adding support for high power (>1W) SFP modules. ==================== Signed-off-by: -
Jon Nettleton authored
This patch is the result of work by both Jon Nettleton and Russell King. Jon wrote the original patch, adding support for SFP modules which require a power level greater than '1'. Russell's changes: - Fix the power levels for big-endian, and make the code flow better. - Convert to use device_property_read_u8() - Warn for power levels exceeding host level SFF-8431 says: "To avoid exceeding system power supply limits and cooling capacity, all modules at power up by default shall operate with up to 1.0 W. Hosts supporting Power Level II or III operation may enable a Power Level II or III module through the 2-wire interface. Power Level II or III modules shall assert the power level declaration bit of SFF-8472." Print a warning for modules that exceed the host power level, and leave them operating in power level 1. - Fix i2c write The first byte of any write after the bus address is always the device address. In order to write a value to device D, address I, value V, we need to generate on the bus: S DDDDDDDD A IIIIIIII A VVVVVVVV A P where S = start, R = restart, A = ack, P = stop. Splitting this as two: S DDDDDDDD A IIIIIIII A R DDDDDDDD A VVVVVVVV A P results in the device's address register being written first by I and then by V - the addressed register within the device is not written. - Avoid power mode switching if 0xa2 is not implemented Some modules indicate that they support power level II or power level III, but do not implement address 0xa2, meaning that the bit to set them to high power mode is not accessible. These modules appear to have the sff8472_compliance field set to zero, and also do not implement diagnostics. Detect this, but also ensure that the module does not require the address switching mode, which we do not implement. - Use mW for power level rather than power level number. - Fix high power mode transition We must not switch to SFP_MOD_PRESENT state until we have finished initialising, because the remaining state machines check for that state. Add SFP_MOD_HPOWER as an intermediate state. - Use definition for I2C register address rather than constant. Signed-off-by:Jon Nettleton <jon@solid-run.com> Signed-off-by:

Negotiate the interface format with the MAC rather than requiring it to be a fixed type specified solely by the SFP module. This allows modules that can work with several different interface signalling formats to select a format compatible with the MAC - for example, a Fiber module supporing Gigabit ethernet and faster connected to a Gigabit only MAC needs to select the 1000BASE-X mode.

Russell King authored
Some BiDi modules (eg, FiberStore SFP-GE-BX) are not compliant with 1000BASE-BX as they use different wavelengths from the 1000BASE-BX standard (eg, 1310nm/1550nm rather than 1310nm/1490nm). These modules support 1000BASE-X ethernet, so detect them by a failure to find any other support, the 8B10B encoding and a bit rate that falls within the 1Gbps window. Signed-off-by:

Saeed Mahameed says: mlx5-update-2018-02-23 (IB representors) From: Mark Bloch <markb@mellanox.com> ========= Add IB representor when in switchdev mode The following series adds support for an IB (RAW Ethernet only) device representor which is created when the user switches to switchdev mode. Today when switching to switchdev mode the only representors which are created are net devices. Each netdev is a representor of a virtual function and any data sent via the representor is received on the virtual function, and any data sent via the virtual function is received by the representor. For the mlx5 driver the main use of this functionality is to be able to use Open vSwitch on the hypervisor in order to manage/control traffic from/to the virtual functions. Open vSwitch can also work with DPDK devices and not just net devices, this series exposes an IB device, which Mellanox PMD driver uses, which then can be used by Open vSwitch DPDK. An IB device representor exposes only RAW Ethernet QP capabilities and the ability to create flow rules to direct traffic to its RX queues. The state of the IB device (ACTIVE/DOWN etc..) is based on the state of the corresponding net device representor. No other RDMA/RoCE functionality is currently supported and no GID table is exposed. ========= Signed-off-by:
