The following patch series tries to fix long standing issues with flow steering code and hopefully preventing silly future bugs. A) Fix an issue where a proper dest type wasn't assigned. B) Refactor and fix dests enums values, refactor deletion function and do proper bookkeeping of dests. C) Change mlx5_del_flow_rules() to delete rules when there are no no more rules attached associated with an FTE. D) Don't call hard coded deletion function but use the node's defined one. E) Add a WARN_ON() to catch future bugs when an FTE with dests is deleted. * tag 'mlx5-updates-2022-05-02' of git://git.kernel.org/pub/scm/linux/kernel/git/saeed/linux: net/mlx5: fs, an FTE should have no dests when deleted net/mlx5: fs, call the deletion function of the node net/mlx5: fs, delete the FTE when there are no rules attached to it net/mlx5: fs, do proper bookkeeping for forward destinations net/mlx5: fs, add unused destination type net/mlx5: fs, jump to exit point and don't fall through net/mlx5: fs, refactor software deletion rule net/mlx5: fs, split software and IFC flow destination definitions net/mlx5e: TC, set proper dest type net/mlx5e: Remove unused mlx5e_dcbnl_build_rep_netdev function net/mlx5e: Drop error CQE handling from the XSK RX handler net/mlx5: Print initializing field in case of timeout net/mlx5: Delete redundant default assignment of runtime devlink params net/mlx5: Remove useless kfree net/mlx5: use kvfree() for kvzalloc() in mlx5_ct_fs_smfs_matcher_create ==================== Link: https://lore.kernel.org/r/ Signed-off-by: Paolo Abeni <pabeni@redhat.com>
2022-05-03Merge branch 'mlxsw-remove-size-limitations-on-egress-descriptor-buffer'Paolo Abeni4-3/+530
Ido Schimmel says: ==================== mlxsw: Remove size limitations on egress descriptor buffer Petr says: Spectrum machines have two resources related to keeping packets in an internal buffer: bytes (allocated in cell-sized units) for packet payload, and descriptors, for keeping headers. Currently, mlxsw only configures the bytes part of the resource management. Spectrum switches permit a full parallel configuration for the descriptor resources, including port-pool and port-TC-pool quotas. By default, these are all configured to use pool 14, with an infinite quota. The ingress pool 14 is then infinite in size. However, egress pool 14 has finite size by default. The size is chip dependent, but always much lower than what the chip actually permits. As a result, we can easily construct workloads that exhaust the configured descriptor limit. Going forward, mlxsw will have to fix this issue properly by maintaining descriptor buffer sizes, TC bindings, and quotas that match the architecture recommendation. Short term, fix the issue by configuring the egress descriptor pool to be infinite in size as well. This will maintain the same configuration philosophy, but will unlock all chip resources to be usable. In this patchset, patch #1 first adds the "desc" field into the pool configuration register. Then in patch #2, the new field is used to configure both ingress and egress pool 14 as infinite. In patches #3 and #4, add a selftest that verifies that a large burst can be absorbed by the shared buffer. This test specifically exercises a scenario where descriptor buffer is the limiting factor and the test fails without the above patches. ==================== Link: https://lore.kernel.org/r/20220502084926.365268-1-idosch@nvidia.com Signed-off-by: Paolo Abeni <pabeni@redhat.com>

2022-05-03mlxsw: Configure descriptor buffersPetr Machata1-0/+26
Spectrum machines have two resources related to keeping packets in an internal buffer: bytes (allocated in cell-sized units) for packet payload, and descriptors, for keeping metadata. Currently, mlxsw only configures the bytes part of the resource management. Spectrum switches permit a full parallel configuration for the descriptor resources, including port-pool and port-TC-pool quotas. By default, these are all configured to use pool 14, with an infinite quota. The ingress pool 14 is then infinite in size. However, egress pool 14 has finite size by default. The size is chip dependent, but always much lower than what the chip actually permits. As a result, we can easily construct workloads that exhaust the configured descriptor limit. Fix the issue by configuring the egress descriptor pool to be infinite in size as well. This will maintain the configuration philosophy of the default configuration, but will unlock all chip resources to be usable. In the code, include both the configuration of ingress and ingress, mostly for clarity.

2022-05-02selftests: forwarding: add Per-Stream Filtering and Policing test for OcelotVladimir Oltean2-0/+562
The Felix VSC9959 switch in NXP LS1028A supports the tc-gate action which enforced time-based access control per stream. A stream as seen by this switch is identified by {MAC DA, VID}. We use the standard forwarding selftest topology with 2 host interfaces and 2 switch interfaces. The host ports must require timestamping non-IP packets and supporting tc-etf offload, for isochron to work. The isochron program monitors network sync status (ptp4l, phc2sys) and deterministically transmits packets to the switch such that the tc-gate action either (a) always accepts them based on its schedule, or (b) always drops them. I tried to keep as much of the logic that isn't specific to the NXP LS1028A in a new tsn_lib.sh, for future reuse. This covers synchronization using ptp4l and phc2sys, and isochron. The cycle-time chosen for this selftest isn't particularly impressive (and the focus is the functionality of the switch), but I didn't really know what to do better, considering that it will mostly be run during debugging sessions, various kernel bloatware would be enabled, like lockdep, KASAN, etc, and we certainly can't run any races with those on. I tried to look through the kselftest framework for other real time applications and didn't really find any, so I'm not sure how better to prepare the environment in case we want to go for a lower cycle time. At the moment, the only thing the selftest is ensuring is that dynamic frequency scaling is disabled on the CPU that isochron runs on. It would probably be useful to have a blacklist of kernel config options (checked through zcat /proc/config.gz) and some cyclictest scripts to run beforehand, but I saw none of those.

THis streamlines the error handling throughout the ieee/mac802154 stack in preparation for sync TX to be introduced for MLME frames. ==================== Link: https://lore.kernel.org/r/20220501194614.1198325-1-stefan@datenfreihafen.org Signed-off-by: Jakub Kicinski <kuba@kernel.org>

Commit a293974590cf ("rtnetlink: avoid frame size warning in rtnl_newlink()") moved to allocating the largest attribute array of rtnl_newlink() on the heap. Kalle reports the stack has grown above 1k again: net/core/rtnetlink.c:3557:1: error: the frame size of 1104 bytes is larger than 1024 bytes [-Werror=frame-larger-than=] Move more attrs to the heap, wrap them in a struct. Don't bother with linkinfo, it's referenced a lot and we take its size so it's awkward to move, plus it's small (6 elements).

2022-05-02Merge branch 'use-mmd-c45-helpers'Paolo Abeni5-45/+52
Andrew Lunn says: ==================== Use MMD/C45 helpers MDIO busses can perform two sorts of bus transaction, defined in clause 22 and clause 45 of 802.3. This results in two register addresses spaces. The current driver structure for indicating if C22 or C45 should be used is messy, and many C22 only bus drivers will wrongly interpret a C45 transaction as a C22 transaction. This patchset is a preparation step to cleanup the situation. It converts MDIO bus users to make use of existing _mmd and _c45 helpers to perform accesses to C45 registers. This will later allow C45 and C22 to be kept separate. ==================== Link: https://lore.kernel.org/r/20220430173037.156823-1-andrew@lunn.ch Signed-off-by: Paolo Abeni <pabeni@redhat.com>

2022-05-02nfp: support VxLAN inner TSO with GSO_PARTIAL offloadFei Qin1-2/+6
VxLAN belongs to UDP-based encapsulation protocol. Inner TSO for VxLAN packet with udpcsum requires offloading of outer header csum. The device doesn't support outer header csum offload. However, inner TSO for VxLAN with udpcsum can still work with GSO_PARTIAL offload, which means outer udp csum computed by stack and inner tcp segmentation finished by hardware. Thus, the patch enable features "NETIF_F_GSO_UDP_TUNNEL_CSUM" and "NETIF_F_GSO_PARTIAL" and set gso_partial_features.

Since o_seqno is now atomic_t, we can always turn on NETIF_F_LLTX for [IP6]GRE[TAP] devices, since we no longer need the TX lock (&txq->_xmit_lock). We could probably do the same thing to [IP6]ERSPAN devices as well, but I'm not familiar with them yet. For example, ERSPAN devices are initialized as |= GRE_FEATURES in erspan_tunnel_init(), but I don't see IP6ERSPAN devices being initialized as |= GRE6_FEATURES. Where should we initialize IP6ERSPAN devices' ->features? Please suggest if I'm missing something, thanks!
