2019-08-22ethernet: Delete unnecessary checks before the macro call “dev_kfree_skb”Markus Elfring20-57/+27
The dev_kfree_skb() function performs also input parameter validation. Thus the test around the shown calls is not needed. This issue was detected by using the Coccinelle software. Signed-off-by: Markus Elfring <elfring@users.sourceforge.net> Signed-off-by: David S. Miller <davem@davemloft.net>
2019-08-22net: fec: add C45 MDIO read/write supportMarco Hartmann1-6/+64
IEEE 802.3ae clause 45 defines a modified MDIO protocol that uses a two staged access model in order to increase the address space. This patch adds support for C45 MDIO read and write accesses, which are used whenever the MII_ADDR_C45 flag in the regnum argument is set. In case it is not set, C22 accesses are used as before.

2019-08-22i40e: allow reset in recovery modePiotr Kwapulinski3-8/+63
Driver waits after issuing a reset. When a reset takes too long a driver gives up. Implemented by invoking PF reset in a loop. After defined number of unsuccessful PF reset trials it returns error. Without this patch PF reset fails when NIC is in recovery mode. So make i40e_set_mac_type() public. i40e driver requires i40e_set_mac_type() to be public. It is required for recovery mode handling. Without this patch recovery mode could not be detected in i40e_probe().

2019-08-22i40e: Fix crash caused by stress setting of VF MAC addressesSlawomir Laba1-1/+6
Add update to the VSI pointer passed to the i40e_set_vf_mac function. If VF is in reset state the driver waits in i40e_set_vf_mac function for the reset to be complete, yet after reset the vsi pointer that was passed into this function is no longer valid. The patch updates local VSI pointer directly from pf->vsi array, by using the id stored in VF pointer (lan_vsi_idx).

The functions i40e_aq_get_phy_abilities_resp() and i40e_set_fc() both have giant structure on the stack, which makes each one use stack frames larger than 500 bytes.

HV VHCA stats agent is responsible on running a preiodic rx/tx packets/bytes stats update. Currently the supported format is version MLX5_HV_VHCA_STATS_VERSION. Block ID 1 is dedicated for statistics data transfer from the VF to the PF. The reporter fetch the statistics data from all opened channels, fill it in a buffer and send it to mlx5_hv_vhca_write_agent.

In addition, upon block 0 invalidate, it should activate all other supported agents with data requests from the PF.

2019-08-22net/mlx5: Add HV VHCA infrastructureEran Ben Elisha4-1/+363
HV VHCA is a layer which provides PF to VF communication channel based on HyperV PCI config channel. It implements Mellanox's Inter VHCA control communication protocol. The protocol contains control block in order to pass messages between the PF and VF drivers, and data blocks in order to pass actual data. The infrastructure is agent based. Each agent will be responsible of contiguous buffer blocks in the VHCA config space. This infrastructure will bind agents to their blocks, and those agents can only access read/write the buffer blocks assigned to them. Each agent will provide three callbacks (control, invalidate, cleanup). Control will be invoked when block-0 is invalidated with a command that concerns this agent. Invalidate callback will be invoked if one of the blocks assigned to this agent was invalidated. Cleanup will be invoked before the agent is being freed in order to clean all of its open resources or deferred works. Block-0 serves as the control block. All execution commands from the PF will be written by the PF over this block. VF will ack on those by writing on block-0 as well. Its format is described by struct mlx5_hv_vhca_control_block layout.

In order to remove dependency on rtnl lock and allow neigh update workqueue task to execute concurrently with tc, refactor mlx5e_rep_neigh_update() for concurrent execution: - Lock encap table when accessing encap entry to prevent concurrent changes. To do this properly, the initial encap state check is moved from mlx5e_rep_neigh_update() into mlx5e_rep_update_flows() to be performed under encap_tbl_lock protection. - Wait for encap to be fully initialized before accessing it by means of 'res_ready' completion. - Add mlx5e_take_all_encap_flows() helper which is used to construct a temporary list of flows and efi indexes that is used to access current encap data in flow which can be attached to multiple encaps simultaneously. Release the flows from temporary list after encap_tbl_lock critical section. This is necessary because mlx5e_flow_put() can't be called while holding encap_tbl_lock. - Modify mlx5e_tc_encap_flows_add() and mlx5e_tc_encap_flows_del() to work with user-provided list of flows built by mlx5e_take_all_encap_flows(), instead of traversing encap flow list directly.

To remove dependency on rtnl lock, always take neigh update encap lock when modifying neigh update hash table and list. Originally, this lock was only used to synchronize with netevent handler function, which is called from bh context and cannot use rtnl lock for synchronization. Take lock in encap entry attach function to prevent concurrent modifications of neigh update hash table and list. Taking the encap lock when creating new nhe introduces a problem that we need to allocate new entry with sleeping GFP_KERNEL flag while holding a spinlock. However, since previous patch in this series has already converted lookup in netevent handler function to user rcu read lock instead of encap lock, we can safely convert the lock type to mutex.

2019-08-21net/mlx5e: Always take reference to neigh entryVlad Buslov2-40/+39
Neigh entry has reference counter, however it is only used when scheduling neigh update event. In all other cases reference to neigh entry is not taken while working with it. Neigh code relies on synchronization provided by rtnl lock and uses encap list size as implicit reference counter. To remove dependency on rtnl lock, always take reference to neigh entry while using it. Remove neigh entry from hash table and delete it only when reference counter reaches zero. This can result spurious neigh update events, when there is an event on entry that has zero encaps attached. However, such events are rare and properly handled by neigh update handler. Extend encap entry with reference to neigh hash entry in order to be able to directly release it when encap is detached, instead of lookup nhe by key through hash table. Extend nhe with reference to device priv structure to guarantee correctness when nhe is used with stack devices, bond setup, in which case it is non-trivial to determine correct device when releasing the nhe.
