Added a new event handler to firmware sync reset, which is used to
support firmware sync reset flow on smart NIC. Adding this new stage to
the flow enables the firmware to ensure host PFs unload before ECPFs
unload, to avoid race of PFs recovery.
If firmware sends sync_reset_unload event to driver the driver should
unload and close all HW resources of the function. Once the driver
finishes unloading part, it can't get any more events from firmware as
event queues are closed, so it polls the reset state field to know when
to continue to next stage of the sync reset flow.
Added capability bit for supporting sync_reset_unload event.

Pull rdma fixes from Jason Gunthorpe:
"This is an unusually large bunch of bug fixes for the later rc cycle,
rxe and mlx5 both dumped a lot of things at once. rxe continues to fix
itself, and mlx5 is fixing a bunch of "queue counters" related bugs.
There is one highly notable bug fix regarding the qkey. This small
security check was missed in the original 2005 implementation and it
allows some significant issues.
Summary:
- Two rtrs bug fixes for error unwind bugs
- Several rxe bug fixes:
* Incorrect Rx packet validation
* Using memory without a refcount
* Syzkaller found use before initialization
* Regression fix for missing locking with the tasklet conversion
from this merge window
- Have bnxt report the correct link properties to userspace, this was
a regression in v6.3
- Several mlx5 bug fixes:
* Kernel crash triggerable by userspace for the RAW ethernet
profile
* Defend against steering refcounting issues created by userspace
* Incorrect change of QP port affinity parameters in some LAG
configurations
- Fix mlx5 Q counters:
* Do not over allocate Q counters to allow userspace to use the
full port capacity
* Kernel crash triggered by eswitch due to mis-use of Q counters
* Incorrect mlx5_device for Q counters in some LAG configurations
- Properly implement the IBA spec restricting privileged qkeys to
root
- Always an error when reading from a disassociated device's event
queue
- isert bug fixes:
* Avoid a deadlock with the CM handler and CM ID destruction
* Correct list corruption due to incorrect locking
* Fix a use after free around connection tear down"

The cited commit aimed to ensure that Virtual Functions (VFs) assign a
queue affinity to a Queue Pair (QP) to distribute traffic when
the LAG master creates a hardware LAG. If the affinity was set while
the hardware was not in LAG, the firmware would ignore the affinity value.
However, this commit unintentionally assigned an affinity to QPs on the LAG
master's VPORT even if the RDMA device was not marked as LAG-enabled.
In most cases, this was not an issue because when the hardware entered
hardware LAG configuration, the RDMA device of the LAG master would be
destroyed and a new one would be created, marked as LAG-enabled.
The problem arises when a user configures Equal-Cost Multipath (ECMP).
In ECMP mode, traffic can be directed to different physical ports based on
the queue affinity, which is intended for use by VPORTS other than the
E-Switch manager. ECMP mode is supported only if both E-Switch managers are
in switchdev mode and the appropriate route is configured via IP. In this
configuration, the RDMA device is not destroyed, and we retain the RDMA
device that is not marked as LAG-enabled.
To ensure correct behavior, Send Queues (SQs) opened by the E-Switch
manager through verbs should be assigned strict affinity. This means they
will only be able to communicate through the native physical port
associated with the E-Switch manager. This will prevent the firmware from
assigning affinity and will not allow the SQs to be remapped in case of
failover.

Previously when destroying a DCT, if the firmware function for the
destruction failed, the common resource would have been destroyed
either way, since it was destroyed before the firmware object.
Which leads to kernel warning "refcount_t: underflow" which indicates
possible use-after-free.
Which is triggered when we try to destroy the common resource for the
second time and execute refcount_dec_and_test(&common->refcount).
So, let's fix the destruction order by factoring out the DCT QP logic
to be in separate XArray database.
refcount_t: underflow; use-after-free.

because it slows down linearly the interface creation time when the

Due to helper function being called from different files, move it to

existing reading from RoCE caps, thus fixing the case where we didn't

2) From Roi, Some cleanups to TC and eswitch modules.
3) Maher migrates vnic diagnostic counters reporting from debugfs to a
dedicated devlink health reporter
Maher Says:
===========
net/mlx5: Expose vnic diagnostic counters using devlink
Currently, vnic diagnostic counters are exposed through the following
debugfs:
$ ls /sys/kernel/debug/mlx5/0000:08:00.0/esw/vf_0/vnic_diag/
cq_overrun
quota_exceeded_command
total_q_under_processor_handle
invalid_command
send_queue_priority_update_flow
nic_receive_steering_discard
The current design does not allow the hypervisor to view the diagnostic
counters of its VFs, in case the VFs get bound to a VM. In other words,
the counters are not exposed for representor interfaces.
Furthermore, the debugfs design is inconvenient future-wise, in case more
counters need to be reported by the driver in the future.
As these counters pertain to vNIC health, it is more appropriate to
utilize the devlink health reporter to expose them.
Thus, this patchest includes the following changes:
* Drop the current vnic diagnostic counters debugfs interface.
* Add a vnic devlink health reporter for PFs/VFs core devices, which
when diagnosed will dump vnic diagnostic counter values that are
queried from FW.
* Add a vnic devlink health reporter for the representor interface, which
serves the same purpose listed in the previous point, in addition to
allowing the hypervisor to view its VFs diagnostic counters, even when
the VFs are bounded to external VMs.
Example of devlink health reporter usage is:
$devlink health diagnose pci/0000:08:00.0 reporter vnic
vNIC env counters:
total_error_queues: 0 send_queue_priority_update_flow: 0
comp_eq_overrun: 0 async_eq_overrun: 0 cq_overrun: 0
invalid_command: 0 quota_exceeded_command: 0

====================
mlx5-updates-2023-04-11
1) Vlad adds the support for linux bridge multicast offload support
Patches #1 through #9
Synopsis
Vlad Says:
==============
Implement support of bridge multicast offload in mlx5. Handle port object
attribute SWITCHDEV_ATTR_ID_BRIDGE_MC_DISABLED notification to toggle multicast
offload and bridge snooping support on bridge. Handle port object
SWITCHDEV_OBJ_ID_PORT_MDB notification to attach a bridge port to MDB.
Steering architecture
Existing offload infrastructure relies on two levels of flow tables - bridge
ingress and egress. For multicast offload the architecture is extended with
additional layer of per-port multicast replication tables. Such tables filter
loopback traffic (so packets are not replicated to their source port) and pop
VLAN headers for "untagged" VLANs. The tables are referenced by the MDB rules in
egress table. MDB egress rule can point to multiple per-port multicast tables,
which causes matching multicast traffic to be replicated to all of them, and,
consecutively, to several bridge ports:
+--------+--+
+---------------------------------------> Port 1 | |
| +-^------+--+
| |
| |
+-----------------------------------------+ | +---------------------------+ |
| EGRESS table | | +--> PORT 1 multicast table | |
+----------------------------------+ +-----------------------------------------+ | | +---------------------------+ |
| INGRESS table | | | | | | | |
+----------------------------------+ | dst_mac=P1,vlan=X -> pop vlan, goto P1 +--+ | | FG0: | |
| | | dst_mac=P1,vlan=Y -> pop vlan, goto P1 | | | src_port=dst_port -> drop | |
| src_mac=M1,vlan=X -> goto egress +---> dst_mac=P2,vlan=X -> pop vlan, goto P2 +--+ | | FG1: | |
| ... | | dst_mac=P2,vlan=Y -> goto P2 | | | | VLAN X -> pop, goto port | |
| | | dst_mac=MDB1,vlan=Y -> goto mcast P1,P2 +-----+ | ... | |
+----------------------------------+ | | | | | VLAN Y -> pop, goto port +-------+
+-----------------------------------------+ | | | FG3: |
| | | matchall -> goto port |
| | | |
| | +---------------------------+
| |
| |
| | +--------+--+
+---------------------------------------> Port 2 | |
| +-^------+--+
| |
| |
| +---------------------------+ |
+--> PORT 2 multicast table | |
+---------------------------+ |
| | |
| FG0: | |
| src_port=dst_port -> drop | |
| FG1: | |
| VLAN X -> pop, goto port | |
| ... | |
| | |
| FG3: | |
| matchall -> goto port +-------+
| |
+---------------------------+
Patches overview:
- Patch 1 adds hardware definition bits for capabilities required to replicate
multicast packets to multiple per-port tables. These bits are used by
following patches to only attempt multicast offload if firmware and hardware
provide necessary support.
- Pathces 2-4 patches are preparations and refactoring.
- Patch 5 implements necessary infrastructure to toggle multicast offload
via SWITCHDEV_ATTR_ID_BRIDGE_MC_DISABLED port object attribute notification.
This also enabled IGMP and MLD snooping.
- Patch 6 implements per-port multicast replication tables. It only supports
filtering of loopback packets.
- Patch 7 extends per-port multicast tables with VLAN pop support for 'untagged'
VLANs.
- Patch 8 handles SWITCHDEV_OBJ_ID_PORT_MDB port object notifications. It
creates MDB replication rules in egress table that can replicate packets to
multiple per-port multicast tables.
- Patch 9 adds tracepoints for MDB events.
==============
2) Parav Create a new allocation profile for SFs, to save on memory
3) Yevgeny provides some initial patches for upcoming software steering
support new pattern/arguments type of modify_header actions.
Starting with ConnectX-6 DX, we use a new design of modify_header FW object.
The current modify_header object allows for having only limited number of
these FW objects, which means that we are limited in the number of offloaded
flows that require modify_header action.
As a preparation Yevgeny provides the following 4 patches:
- Patch 1: Add required mlx5_ifc HW bits
- Patch 2, 3: Add new WQE type and opcode that is required for pattern/arg
support and adds appropriate support in dr_send.c
- Patch 4: Add ICM pool for modify-header-pattern objects and implement
patterns cache, allowing patterns reuse for different flows

mlx5-updates-2023-03-20
mlx5 dynamic msix
This patch series adds support for dynamic msix vectors allocation in mlx5.
Eli Cohen Says:
================
The following series of patches modifies mlx5_core to work with the
dynamic MSIX API. Currently, mlx5_core allocates all the interrupt
vectors it needs and distributes them amongst the consumers. With the
introduction of dynamic MSIX support, which allows for allocation of
interrupts more than once, we now allocate vectors as we need them.
This allows other drivers running on top of mlx5_core to allocate
interrupt vectors for their own use. An example for this is mlx5_vdpa,
which uses these vectors to propagate interrupts directly from the
hardware to the vCPU [1].
As a preparation for using this series, a use after free issue is fixed
in lib/cpu_rmap.c and the allocator for rmap entries has been modified.
A complementary API for irq_cpu_rmap_add() has also been introduced.
