2018-03-04net: dsa: mv88e6xxx: Hold mutex while doing stats operationsAndrew Lunn
Until now, there has been no need to hold the reg mutex while getting the count of statistics, or the strings, because the hardware was not accessed. When adding support for SERDES statistics, it is necessary to access the hardware, to determine if a port is using the SERDES interface. So add mutex lock/unlocks.

By passing the port, we allow different ports to have different statistics. This is useful since some ports have SERDES interfaces with their own statistic counters.

2018-03-02net: Convert hwsim_net_opsKirill Tkhai
These pernet_operations allocate and destroy IDA identifier, and these actions are synchronized by IDA subsystem locks. Exit method removes mac80211_hwsim_data enteries from the lists, and this is synchronized by hwsim_radio_lock with the rest parallel pernet_operations. Also it queues destroy_radio() work, and these work already may be executed in parallel with any pernet_operations (as it's a work :). So, we may mark these pernet_operations as async.

2018-03-02mac80211_hwsim: Make hwsim_netgroup IDAKirill Tkhai
hwsim_netgroup counter is declarated as int, and it is incremented every time a new net is created. After sizeof(int) net are created, it will overflow, and different net namespaces will have the same identifier. This patch fixes the problem by introducing IDA instead of int counter. IDA guarantees, all the net namespaces have the uniq identifier. Note, that after we do ida_simple_remove() in hwsim_exit_net(), and we destroy the ID, later there may be executed destroy_radio() from the workqueue. But destroy_radio() does not use the ID, so it's OK. Out of bounds of this patch, just as a report to wireless subsystem maintainer, destroy_radio() increaments hwsim_radios_generation without hwsim_radio_lock, so this may need one more patch to fix.

As a part of working on MII time stamping infrastructure, I was trying to figure out how netdev->phydev gets assigned, and I stumbled across this. Ever since the new phylink code came in, the field is assigned twice. The function, phylink_connect_phy(), calls phy_attach_direct() phylink_bringup_phy() and phy_attach_direct() sets dev->phydev = phydev; but phylink_bringup_phy() then sets the same field again: pl->netdev->phydev = phy; Similarly, the function, phylink_of_phy_connect(), calls of_phy_attach() phy_attach_direct() phylink_bringup_phy() The removal code is also duplicated: phylink_disconnect_phy() pl->netdev->phydev = NULL; phy_disconnect() phy_detach() phydev->attached_dev->phydev = NULL; This patch removes the redundant assignments, restricting manipulation of the netdev.phydev field to phy_attach_direct() and phy_detach().

2018-02-28ipvlan: use per device spinlock to protect addrs list updatesPaolo Abeni
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.

2018-02-28net: mvpp2: Add hardware offloading for VLAN filteringMaxime Chevallier
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: Maxime Chevallier <maxime.chevallier@bootlin.com> Signed-off-by: David S. Miller <davem@davemloft.net>

2018-02-28sfp: add high power module supportJon Nettleton
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.

2018-02-28sfp: support 1G BiDi (eg, FiberStore SFP-GE-BX) modulesRussell King
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.

Use extack inside team's enslavement function and also propagate it to the netdevice notifier to allow enslaved ports to report the failure reason. Example: $ teamd -t team0 -d -c '{"runner": {"name": "lacp"}}' $ ip link set dev lo master team0 Error: Loopback device can't be added as a team port.

2018-02-28fm10k: fix incorrect warning for function prototypeJacob Keller
Recent kernels now complain about incorrect function prototype comments, in order to ensure comments are accurate to the function. However, it incorrectly associates the comment above the fm10k_pci_tbl[] as a function header comment. Fix this by removing the extra "*" in the comment. This normally indicates that the function is a doxygen style function header comment. Once removed, the logic no longer kicks in and the following warning is fixed: warning: cannot understand function prototype: 'const struct pci_device_id fm10k_pci_tbl[] = ' Signed-off-by: Jacob Keller <jacob.e.keller@intel.com> Tested-by: Krishneil Singh <krishneil.k.singh@intel.com> Signed-off-by: Jeff Kirsher <jeffrey.t.kirsher@intel.com>
2018-02-28fm10k: fix function doxygen commentsJacob Keller
Several function header comments had incorrect function parameter definitions. Recent versions of the upstream kernel have started to warn about these issues. Fix up the comments which do not match in order to resolve these new warnings. While fixing these, update the copyright year also.

git://git.kernel.org/pub/scm/linux/kernel/git/mellanox/linux 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: David S. Miller <davem@davemloft.net>
2018-02-27net/mlx4_en: RX csum, pre-define enabled protocols for IP status maskingTariq Toukan
Pre-define a mask for IP status of a completion, that tests the MLX4_CQE_STATUS_IPV6 only in case CONFIG_IPV6 is enabled. Use it for IP status testing upon completion, instead of separating the datapath into two flows. This takes common code structures (such as closing parenthesis) back to their original place, and makes code more readable. Signed-off-by: Tariq Toukan <tariqt@mellanox.com> Suggested-by: David S.
