2021-11-16net/mlx5: E-switch, Create QoS on demandDmytro Linkin
Don't create eswitch QoS (root TSAR) on switch mode change. Create it on first child TSAR object creation - vport or rate group. Keep track root TSAR references and release root TSAR with last object deletion. No need to check for QoS is enabled when installing tc matchall filter. Remove related helper function due to no users of it.

2021-11-16net/mlx5: E-switch, Enable vport QoS on demandDmytro Linkin
Vports' QoS is not commonly used but consume SW/HW resources, which becomes an issue on BlueField SoC systems. Don't enable QoS on vports by default on eswitch mode change and enable when it's going to be used by one of the top level users: - configuring TC matchall filter with police action; - setting rate with legacy NDO API; - calling devlink ops->rate_leaf_*() callbacks. Disable vport QoS on vport cleanup.

An eswitch vport of the devlink port is always enabled before a devlink port is registered. And a eswitch vport is always disabled after a devlink port is unregistered.

2021-11-16net/mlx5e: Specify out ifindex when looking up decap routeChris Mi
There is a use case that the local and remote VTEPs are in the same host. Currently, the out ifindex is not specified when looking up the decap route for offloads. So in this case, a local route is returned and the route dev is lo. Actual tunnel interface can be created with a parameter "dev" [1], which specifies the physical device to use for tunnel endpoint communication. Pass this parameter to driver when looking up decap route for offloads. So that a unicast route will be returned.

2021-11-16net: stmmac: Fix signed/unsigned wreckageThomas Gleixner
The recent addition of timestamp correction to compensate the CDC error introduced a subtle signed/unsigned bug in stmmac_get_tx_hwtstamp() while it managed for some obscure reason to avoid that in stmmac_get_rx_hwtstamp(). The issue is: s64 adjust = 0; u64 ns; adjust += -(2 * (NSEC_PER_SEC / priv->plat->clk_ptp_rate)); ns += adjust; works by chance on 64bit, but falls apart on 32bit because the compiler knows that adjust fits into 32bit and then treats the addition as a u64 + u32 resulting in an off by ~2 seconds failure. The RX variant uses an u64 for adjust and does the adjustment via ns -= adjust; because consistency is obviously overrated. Get rid of the pointless zero initialized adjust variable and do: ns -= (2 * NSEC_PER_SEC) / priv->plat->clk_ptp_rate; which is obviously correct and spares the adjust obfuscation. Aside of that it yields a more accurate result because the multiplication takes place before the integer divide truncation and not afterwards. Stick the calculation into an inline so it can't be accidentally disimproved. Return an u32 from that inline as the result is guaranteed to fit which lets the compiler optimize the substraction.

2021-11-16net/mlx5: Lag, update tracker when state change event receivedMaher Sanalla
Currently, In NETDEV_CHANGELOWERSTATE/NETDEV_CHANGEUPPERSTATE events handling, tracking is not fully completed if the LAG device is not ready at the time the events occur. But, we must keep track of the upper and lower states after receiving the events because RoCE needs this info in mlx5_lag_get_roce_netdev() - in order to return the corresponding port that its running on. Returning the wrong (not most recent) port will lead to gids table being incorrect. For example: If during the attachment of a slave to the bond, the other non-attached port performs pci_reload, then the LAG device is not ready, but that should not result in dismissing attached slave tracker update automatically (which is performed in mlx5_handle_changelowerstate()), Since these events might not come later, which can lead to both bond ports having tx_enabled=0 - which is not a valid state of LAG bond.

2021-11-16net/mlx5e: CT, Fix multiple allocations and memleak of mod actsRoi Dayan
CT clear action offload adds additional mod hdr actions to the flow's original mod actions in order to clear the registers which hold ct_state. When such flow also includes encap action, a neigh update event can cause the driver to unoffload the flow and then reoffload it. Each time this happens, the ct clear handling adds that same set of mod hdr actions to reset ct_state until the max of mod hdr actions is reached. Also the driver never releases the allocated mod hdr actions and causing a memleak. Fix above two issues by moving CT clear mod acts allocation into the parsing actions phase and only use it when offloading the rule. The release of mod acts will be done in the normal flow_put(). backtrace: [<000000007316e2f3>] krealloc+0x83/0xd0 [<00000000ef157de1>] mlx5e_mod_hdr_alloc+0x147/0x300 [mlx5_core] [<00000000970ce4ae>] mlx5e_tc_match_to_reg_set_and_get_id+0xd7/0x240 [mlx5_core] [<0000000067c5fa17>] mlx5e_tc_match_to_reg_set+0xa/0x20 [mlx5_core] [<00000000d032eb98>] mlx5_tc_ct_entry_set_registers.isra.0+0x36/0xc0 [mlx5_core] [<00000000fd23b869>] mlx5_tc_ct_flow_offload+0x272/0x1f10 [mlx5_core] [<000000004fc24acc>] mlx5e_tc_offload_fdb_rules.part.0+0x150/0x620 [mlx5_core] [<00000000dc741c17>] mlx5e_tc_encap_flows_add+0x489/0x690 [mlx5_core] [<00000000e92e49d7>] mlx5e_rep_update_flows+0x6e4/0x9b0 [mlx5_core] [<00000000f60f5602>] mlx5e_rep_neigh_update+0x39a/0x5d0 [mlx5_core] Fixes: 1ef3018f5af3 ("net/mlx5e: CT: Support clear action") Signed-off-by: Roi Dayan <roid@nvidia.com> Reviewed-by: Paul Blakey <paulb@nvidia.com> Reviewed-by: Maor Dickman <maord@nvidia.com> Signed-off-by: Saeed Mahameed <saeedm@nvidia.com>

2021-11-16net/mlx5: E-Switch, rebuild lag only when neededMark Bloch
A user can enable VFs without changing E-Switch mode, this can happen when a user moves straight to switchdev mode and only once in switchdev VFs are enabled via the sysfs interface. The cited commit assumed this isn't possible and exposed a single API function where the E-switch calls into the lag code, breaks the lag and prevents any other lag operations to take place until the E-switch update has ended. Breaking the hardware lag when it isn't needed can make it such that hardware lag can't be enabled again. In the sysfs call path check if the current E-Switch mode is NONE, in the context of the function it can only mean the E-Switch is moving out of NONE mode and the hardware lag should be disabled and enabled once the mode change has ended. If the mode isn't NONE it means VFs are about to be enabled and such operation doesn't require toggling the hardware lag.

2021-11-16net/mlx5: E-Switch, Fix resetting of encap mode when entering switchdevPaul Blakey
E-Switch encap mode is relevant only when in switchdev mode. The RDMA driver can query the encap configuration via mlx5_eswitch_get_encap_mode(). Make sure it returns the currently used mode and not the set one. This reverts the cited commit which reset the encap mode on entering switchdev and fixes the original issue properly.

2021-11-16net/mlx5e: Wait for concurrent flow deletion during neigh/fib eventsVlad Buslov
Function mlx5e_take_tmp_flow() skips flows with zero reference count. This can cause syndrome 0x179e84 when the called from neigh or route update code and the skipped flow is not removed from the hardware by the time underlying encap/decap resource is deleted. Add new completion 'del_hw_done' that is completed when flow is unoffloaded. This is safe to do because flow with reference count zero needs to be detached from encap/decap entry before its memory is deallocated, which requires taking the encap_tbl_lock mutex that is held by the event handlers code.

2021-11-15net: macb: Fix several edge cases in validateSean Anderson
There were several cases where validate() would return bogus supported modes with unusual combinations of interfaces and capabilities. For example, if state->interface was 10GBASER and the macb had HIGH_SPEED and PCS but not GIGABIT MODE, then 10/100 modes would be set anyway. In another case, SGMII could be enabled even if the mac was not a GEM (despite this being checked for later on in mac_config()). These inconsistencies make it difficult to refactor this function cleanly. There is still the open question of what exactly the requirements for SGMII and 10GBASER are, and what SGMII actually supports. If someone from Cadence (or anyone else with access to the GEM/MACB datasheet) could comment on this, it would be greatly appreciated. In particular, what is supported by Cadence vs. vendor extension/limitation? To address this, the current logic is split into three parts. First, we determine what we support, then we eliminate unsupported interfaces, and finally we set the appropriate link modes. There is still some cruft related to NA, but this can be removed in a future patch.

2021-11-15iavf: prevent accidental free of filter structureJacob Keller
In iavf_config_clsflower, the filter structure could be accidentally released at the end, if iavf_parse_cls_flower or iavf_handle_tclass ever return a non-zero but positive value. In this case, the function continues through to the end, and will call kfree() on the filter structure even though it has been added to the linked list. This can actually happen because iavf_parse_cls_flower will return a positive IAVF_ERR_CONFIG value instead of the traditional negative error codes. Fix this by ensuring that the kfree() check and error checks are similar. Use the more idiomatic "if (err)" to catch all non-zero error codes.
