2023-01-18net: mlx5: eliminate anonymous module_init & module_exitRandy Dunlap
Eliminate anonymous module_init() and module_exit(), which can lead to confusion or ambiguity when reading System.map, crashes/oops/bugs, or an initcall_debug log. Give each of these init and exit functions unique driver-specific names to eliminate the anonymous names. Example 1: (System.map) ffffffff832fc78c t init ffffffff832fc79e t init ffffffff832fc8f8 t init Example 2: (initcall_debug log) calling init+0x0/0x12 @ 1 initcall init+0x0/0x12 returned 0 after 15 usecs calling init+0x0/0x60 @ 1 initcall init+0x0/0x60 returned 0 after 2 usecs calling init+0x0/0x9a @ 1 initcall init+0x0/0x9a returned 0 after 74 usecs Fixes: e126ba97dba9 ("mlx5: Add driver for Mellanox Connect-IB adapters") Signed-off-by: Randy Dunlap <rdunlap@infradead.org> Cc: Eli Cohen <eli@mellanox.com> Cc: Saeed Mahameed <saeedm@nvidia.com> Cc: Leon Romanovsky <leon@kernel.org> Cc: linux-rdma@vger.kernel.org Reviewed-by: Ira Weiny <ira.weiny@intel.com> Reviewed-by: Leon Romanovsky <leonro@nvidia.com> Signed-off-by: Saeed Mahameed <saeedm@nvidia.com>
2023-01-18net/mlx5: E-switch, Fix switchdev mode after devlink reloadChris Mi
The cited commit removes eswitch mode none. So after devlink reload in switchdev mode, eswitch mode is not changed. But actually eswitch is disabled during devlink reload. Fix it by setting eswitch mode to legacy when disabling eswitch which is called by reload_down.

2023-01-18net/mlx5e: Protect global IPsec ASOLeon Romanovsky
ASO operations are global to whole IPsec as they share one DMA address for all operations. As such all WQE operations need to be protected with lock. In this case, it must be spinlock to allow mlx5e_ipsec_aso_query() operate in atomic context.

2023-01-18net/mlx5e: Remove optimization which prevented update of ESN stateLeon Romanovsky
aso->use_cache variable introduced in commit 8c582ddfbb47 ("net/mlx5e: Handle hardware IPsec limits events") was an optimization to skip recurrent calls to mlx5e_ipsec_aso_query(). Such calls are possible when lifetime event is generated: -> mlx5e_ipsec_handle_event() -> mlx5e_ipsec_aso_query() - first call -> xfrm_state_check_expire() -> mlx5e_xfrm_update_curlft() -> mlx5e_ipsec_aso_query() - second call However, such optimization not really effective as mlx5e_ipsec_aso_query() is needed to be called for update ESN anyway, which was missed due to misplaced use_cache assignment.

2023-01-18net/mlx5e: Set decap action based on attr for sampleChris Mi
Currently decap action is set based on tunnel_id. That means it is set unconditionally. But for decap, ct and sample actions, decap is done before ct. No need to decap again in sample. And the actions are set correctly when parsing. So set decap action based on attr instead of tunnel_id.

2023-01-18net/mlx5e: Remove redundant xsk pointer check in mlx5e_mpwrq_validate_xskAdham Faris
This validation function is relevant only for XSK cases, hence it assumes to be called only with xsk != NULL. Thus checking for invalid xsk pointer is redundant and misleads static code analyzers. This commit removes redundant xsk pointer check. This solves the following smatch warning: drivers/net/ethernet/mellanox/mlx5/core/en/params.c:481 mlx5e_mpwrq_validate_xsk() error: we previously assumed 'xsk' could be null (see line 478) Fixes: 6470d2e7e8ed ("net/mlx5e: xsk: Use KSM for unaligned XSK") Signed-off-by: Adham Faris <afaris@nvidia.com> Reported-by: kernel test robot <lkp@intel.com> Reported-by: Dan Carpenter <error27@gmail.com> Reviewed-by: Tariq Toukan <tariqt@nvidia.com> Signed-off-by: Saeed Mahameed <saeedm@nvidia.com>
2023-01-18net/mlx5e: Avoid false lock dependency warning on tc_ht even moreVlad Buslov
The cited commit changed class of tc_ht internal mutex in order to avoid false lock dependency with fs_core node and flow_table hash table structures. However, hash table implementation internally also includes a workqueue task with its own lockdep map which causes similar bogus lockdep splat[0]. Fix it by also adding dedicated class for hash table workqueue work structure of tc_ht.

A user is able to configure an arbitrary number of rx queues when creating an interface via netlink. This doesn't work for child PKEY interfaces because the child interface uses the parent receive channels. Although the child shares the parent's receive channels, the number of rx queues is important for the channel_stats array: the parent's rx channel index is used to access the child's channel_stats. So the array has to be at least as large as the parent's rx queue size for the counting to work correctly and to prevent out of bound accesses. This patch checks for the mentioned scenario and returns an error when trying to create the interface. The error is propagated to the user.

2023-01-09net/mlx5e: IPoIB, Block queue count configuration when sub interfaces are ↵Dragos Tatulea
present PKEY sub interfaces share the receive queues with the parent interface. While setting the sub interface queue count is not supported, it is currently possible to change the number of queues of the parent interface. Thus we can end up with inconsistent queue sizes between the parent and its sub interfaces. This change disallows setting the queue count on the parent interface when sub interfaces are present. This is achieved by introducing an explicit reference to the parent netdev in the mlx5i_priv of the child interface. An additional counter is also required on the parent side to detect when sub interfaces are attached and for proper cleanup. The rtnl lock is taken during the ethtool op and the sub interface ndo_init/uninit ops. There is no race here around counting the sub interfaces, reading the sub interfaces and setting the number of channels. The ASSERT_RTNL was added to document that.

Current xdp xmit functions logic (mlx5e_xmit_xdp_frame_mpwqe or mlx5e_xmit_xdp_frame), validates xdp packet length by comparing it to hw mtu (configured at xdp sq allocation) before xmiting it. This check does not account for ethernet fcs length (calculated and filled by the nic). Hence, when we try sending packets with length > (hw-mtu - ethernet-fcs-size), the device port drops it and tx_errors_phy is incremented. Desired behavior is to catch these packets and drop them by the driver. Fix this behavior in XDP SQ allocation function (mlx5e_alloc_xdpsq) by subtracting ethernet FCS header size (4 Bytes) from current hw mtu value, since ethernet FCS is calculated and written to ethernet frames by the nic.

But when other dests encap become invalid, they are not cleared due to slow path flag of the flow. When neigh-update-add is running, it will use invalid encap. Fix it by checking slow path flag after clearing dest encap.

2022-12-28net/mlx5: Avoid recovery in probe flowsShay Drory
Currently, recovery is done without considering whether the device is still in probe flow. This may lead to recovery before device have finished probed successfully. e.g.: while mlx5_init_one() is running. Recovery flow is using functionality that is loaded only by mlx5_init_one(), and there is no point in running recovery without mlx5_init_one() finished successfully. Fix it by waiting for probe flow to finish and checking whether the device is probed before trying to perform recovery.

SW steering is able to match only on the exact values of the packet fields, as requested by the user: the user provides mask for the fields that are of interest, and the exact values to be matched on when the traffic is handled. The following patch series add new type of action - Range Match, where the user provides a field to be matched on and a range of values (min to max) that will be considered as hit. There are several new notions that were implemented in order to support Range Match: - MATCH_RANGES Steering Table Entry (STE): the new STE type that allows matching the packets' fields on the range of values instead of a specific value. - Match Definer: this is a general FW object that defines which fields in the packet will be referenced by the mask and tag of each STE. Match definer ID is part of STE fields, and it defines how the HW needs to interpret the STE's mask/tag values. Till now SW steering used the definers that were managed by FW and implemented the STE layout as described by the HW spec. Now that we're adding a new type of STE, SW steering needs to also be able to define this new STE's layout, and this is do ======================= 2) From OZ add support for meter mtu offload 2.1: Refactor the code to allow both metering and range post actions as a pre-step for adding police mtu offload support. 2.2: Instantiate mtu green/red flow tables with a single match-all rule.

2022-12-08mlxsw: spectrum_ipip: Rename Spectrum-2 ip6gre operationsIdo Schimmel
There are two main differences between Spectrum-1 and newer ASICs in terms of IP-in-IP support: 1. In Spectrum-1, RIFs representing ip6gre tunnels require two entries in the RIF table. 2. In Spectrum-2 and newer ASICs, packets ingress the underlay (during encapsulation) and egress the underlay (during decapsulation) via a special generic loopback RIF. The first difference was handled in previous patches by adding the 'double_rif_entry' field to the Spectrum-1 operations structure of ip6gre RIFs. The second difference is handled during RIF creation, by only creating a generic loopback RIF in Spectrum-2 and newer ASICs. Therefore, the ip6gre operations can be shared between Spectrum-1 and newer ASIC in a similar fashion to how the ipgre operations are shared. Rename the operations to not be Spectrum-2 specific and move them earlier in the file so that they could later be used for Spectrum-1.
