      net/mlx5: Fix too early queueing of log timestamp work · 924cc463
      Gal Pressman authored 
      The log timestamp work should not be queued before the command interface
is initialized, move it to a later stage in the init flow.

      net/mlx5: Fix use after free in mlx5_health_wait_pci_up · 76091b0f
      Amir Tzin authored 
      The device health recovery flow calls mlx5_health_wait_pci_up() which
queries the device for FW_RESET timeout after freeing the device
timeouts structure on mlx5_function_teardown(). Fix this bug by moving
timeouts structure init/cleanup to the device's init/uninit phases.
Since it is necessary to reset default software timeouts on function
reload, extract setting of defaults values from mlx5_tout_init() and
call mlx5_tout_set_def_val() directly from mlx5_function_setup().

      net/mlx5: E-Switch, Use indirect table only if all destinations support it · e219440d
      Maor Dickman authored 
      When adding rule with multiple destinations, indirect table is used for all of
the destinations if at least one of the destinations support it, this can cause
creation of invalid indirect tables for the destinations that doesn't support it.

Fixed it by using indirect table only if all destinations support it.

      net/mlx5: E-Switch, fix single FDB creation on BlueField · 43a0696f
      Mark Bloch authored 
      Always use MLX5_FLOW_TABLE_OTHER_VPORT flag when creating egress ACL
table for single FDB. Not doing so on BlueField will make firmware fail
the command. On BlueField the E-Switch manager is the ECPF (vport 0xFFFE)
which is filled in the flow table creation command but as the
other_vport field wasn't set the firmware complains about a bad parameter.

This is different from a regular HCA where the E-Switch manager vport is
the PF (vport 0x0). Passing MLX5_FLOW_TABLE_OTHER_VPORT will make the
firmware happy both on BlueField and on regular HCAs without special
condition for each.

This fixes the bellow firmware syndrome:
mlx5_cmd_check:819:(pid 571): CREATE_FLOW_TABLE(0x930) op_mod(0x0) failed, status bad parameter(0x3), syndrome (0x754a4)

      net/mlx5: E-switch, Respect BW share of the new group · 1e59b32e
      Dmytro Linkin authored 
      To enable transmit schduler on vport FW require non-zero configuration
for vport's TSAR. If vport added to the group which has configured BW
share value and TX rate values of the vport are zero, then scheduler
wouldn't be enabled on this vport.
Fix that by calling BW normalization if BW share of the new group is
configured.

      net/mlx5e: Sync TIR params updates against concurrent create/modify · 4cce2ccf
      Tariq Toukan authored 
      Transport Interface Receive (TIR) objects perform the packet processing and
reassembly and is also responsible for demultiplexing the packets into the
different RQs.

There are certain TIR context attributes that propagate to the pointed RQs
and applied to them (like packet_merge offloads (LRO/SHAMPO) and
tunneled_offload_en).  When TIRs do not agree on attributes values, a "last
one wins" policy is applied.  Hence, if not synced properly, a race between
TIR params update and a concurrent TIR create/modify operation might yield
to a mismatch between the shadow parameters in SW and the actual applied
state of the RQs in HW.

tunneled_offload_en is a fixed attribute per profile, while packet merge
offload state might be toggled and get out-of-sync. When this happens,
packet_merge offload might be working although not requested, or the
opposite.

All updates to packet_merge state and all create/modify operations of
regular redirection/steering TIRs are done under the same priv->state_lock,
so they do not run in parallel, and no race is possible.

However, there are other kind of TIRs (acceleration offloads TIRs, like TLS
TIRs) which are created on demand for each new connection without holding
the coarse priv->state_lock, hence might race.

Fix this by synchronizing all packet_merge state reads and writes against
all TIR create/modify operations. Include the modify operations of the
regular redirection steering TIRs under the new lock, for better code
layering and division of responsibilities.
