Previously when we had a RAW QP, we bound a counter to it when it moved to INIT state, using the counter context inside RQC. But when we try to modify that counter later in RTS state we used modify QP which tries to change the counter inside QPC instead of RQC. Now we correctly modify the counter set_id inside of RQC instead of QPC for the RAW QP. Fixes: d14133dd ("IB/mlx5: Support set qp counter") Signed-off-by:

This series from Patrisious extends mlx5 to support IPsec packet offload in multiport devices (MPV, see [1] for more details). These devices have single flow steering logic and two netdev interfaces, which require extra logic to manage IPsec configurations as they performed on netdevs. Thanks [1] https://lore.kernel.org/linux-rdma/20180104152544.28919-1-leon@kernel.org/ Link: https://lore.kernel.org/all/20231002083832.19746-1-leon@kernel.orgSigned-of-by:

Flexible array members annotated with __counted_by can have their accesses bounds-checked at run-time checking via CONFIG_UBSAN_BOUNDS (for array indexing) and CONFIG_FORTIFY_SOURCE (for strcpy/memcpy-family functions).

Compared with normal doorbell, using record doorbell can shorten the process of ringing the doorbell and reduce the latency. Add a flag HNS_ROCE_CAP_FLAG_SRQ_RECORD_DB to allow FW to enable/disable SRQ record doorbell. If the flag above is set, allocate the dma buffer for SRQ record doorbell and write the buffer address into SRQC during SRQ creation. For userspace SRQ, add a flag HNS_ROCE_RSP_SRQ_CAP_RECORD_DB to notify userspace whether the SRQ record doorbell is enabled. Signed-off-by:

When the master device is unbinded, make sure to clean up all of the steering rules or flow tables that were created over the master, in order to allow proper unbinding of master, and for ethernet traffic to continue to work independently. Upon bringing master device back up and attaching the slave to it, checks if the slave already has IPsec configured and if so reconfigure the rules needed to support RoCE traffic. Note that while master device is unbound, the user is unable to configure IPsec again, since they are in a kind of illegal state in which they are in MPV mode but the slave has no master. However if IPsec was configured before hand, it will continue to work for ethernet traffic while master is unbound, and would continue to work for all traffic when the master is bound back again.

Add empty flow table in RDMA_RX master domain, to forward all received traffic to it, in order to continue through the FW RoCE steering. In order to achieve that however, first we check if the decrypted traffic is RoCEv2, if so then forward it to RDMA_RX domain. But in case the traffic is coming from the slave, have to first send the traffic to an alias table in order to switch gvmi and from there we can go to the appropriate gvmi flow table in RDMA_RX master domain.

Add functions which allow one vhca to access another vhca object, and functions that creates an alias object or destroys it.

If the device is in MPV mode, the ethernet driver would now register to events from IB driver about core devices affiliation or de-affiliation. Use the key provided in said event to connect each mlx5e priv instance to it's master counterpart, this way the ethernet driver is now aware of who is his master core device and even more, such as knowing if partner device has IPsec configured or not.

Currently, mkeys are managed via xarray. This implementation leads to a degradation in cases many MRs are unregistered in parallel, due to xarray internal implementation, for example: deregistration 1M MRs via 64 threads is taking ~15% more time[1]. Hence, implement mkeys management via LIFO queue, which solved the degradation. [1] 2.8us in kernel v5.19 compare to 3.2us in kernel v6.4 Signed-off-by:

Pull tracing fixes from Steven Rostedt: - Fix the "bytes" output of the per_cpu stat file The tracefs/per_cpu/cpu*/stats "bytes" was giving bogus values as the accounting was not accurate. It is suppose to show how many used bytes are still in the ring buffer, but even when the ring buffer was empty it would still show there were bytes used. - Fix a bug in eventfs where reading a dynamic event directory (open) and then creating a dynamic event that goes into that diretory screws up the accounting. On close, the newly created event dentry will get a "dput" without ever having a "dget" done for it. The fix is to allocate an array on dir open to save what dentries were actually "dget" on, and what ones to "dput" on close. * tag 'trace-v6.6-rc2' of git://git.kernel.org/pub/scm/linux/kernel/git/trace/linux-trace: eventfs: Remember what dentries were created on dir open ring-buffer: Fix bytes info in per_cpu buffer stats

Pull cxl fixes from Dan Williams: "A collection of regression fixes, bug fixes, and some small cleanups to the Compute Express Link code. The regressions arrived in the v6.5 dev cycle and missed the v6.6 merge window due to my personal absences this cycle. The most important fixes are for scenarios where the CXL subsystem fails to parse valid region configurations established by platform firmware. This is important because agreement between OS and BIOS on the CXL configuration is fundamental to implementing "OS native" error handling, i.e. address translation and component failure identification. Other important fixes are a driver load error when the BIOS lets the Linux PCI core handle AER events, but not CXL memory errors. The other fixex might have end user impact, but for now are only known to trigger in our test/emulation environment. Summary: - Fix multiple scenarios where platform firmware defined regions fail to be assembled by the CXL core. - Fix a spurious driver-load failure on platforms that enable OS native AER, but not OS native CXL error handling. - Fix a regression detecting "poison" commands when "security" commands are also defined. - Fix a cxl_test regression with the move to centralize CXL port register enumeration in the CXL core. - Miscellaneous small fixes and cleanups" * tag 'cxl-fixes-6.6-rc3' of git://git.kernel.org/pub/scm/linux/kernel/git/cxl/cxl: cxl/acpi: Annotate struct cxl_cxims_data with __counted_by cxl/port: Fix cxl_test register enumeration regression cxl/region: Refactor granularity select in cxl_port_setup_targets() cxl/region: Match auto-discovered region decoders by HPA range cxl/mbox: Fix CEL logic for poison and security commands cxl/pci: Replace host_bridge->native_aer with pcie_aer_is_native() PCI/AER: Export pcie_aer_is_native() cxl/pci: Fix appropriate checking for _OSC while handling CXL RAS registers
