2023-10-24RDMA/core: Remove NULL check before dev_{put, hold}Yang Li
The call netdev_{put, hold} of dev_{put, hold} will check NULL, so there is no need to check before using dev_{put, hold}, remove it to silence the warning: ./drivers/infiniband/core/nldev.c:375:2-9: WARNING: NULL check before dev_{put, hold} functions is not needed.

2023-10-24RDMA/mlx5: Change the key being sent for MPV device affiliationPatrisious Haddad
Change the key that we send from IB driver to EN driver regarding the MPV device affiliation, since at that stage the IB device is not yet initialized, so its index would be zero for different IB devices and cause wrong associations between unrelated master and slave devices. Instead use a unique value from inside the core device which is already initialized at this stage.

bnxt_re_handle_cq_async_error() Clang warns (or errors with CONFIG_WERROR=y): drivers/infiniband/hw/bnxt_re/main.c:1114:2: error: unannotated fall-through between switch labels [-Werror,-Wimplicit-fallthrough] 1114 | default: | ^ drivers/infiniband/hw/bnxt_re/main.c:1114:2: note: insert 'break;' to avoid fall-through 1114 | default: | ^ | break; 1 error generated. Clang is a little more pedantic than GCC, which does not warn when falling through to a case that is just break or return. Clang's version is more in line with the kernel's own stance in deprecated.rst, which states that all switch/case blocks must end in either break, fallthrough, continue, goto, or return. Add the missing break to silence the warning.

2023-10-19RDMA/hns: Fix init failure of RoCE VF and HIP08Junxian Huang
During device init, a struct for HW stats will be allocated. As HW stats are not supported for VF and HIP08, currently hns_roce_alloc_hw_port_stats() returns NULL in this case. However, ib-core considers the returned NULL pointer as memory allocation failure and returns ENOMEM, eventually leading to the failure of VF and HIP08 init. In the case where the driver does not support the .alloc_hw_port_stats() ops, ib-core will return EOPNOTSUPP and ignore this error code in the upper layer function. So for VF and HIP08, just don't set the HW stats ops to ib-core.

2023-10-19RDMA/hns: Fix printing level of asynchronous eventsChengchang Tang
The current driver will print all asynchronous events. Some of the print levels are set improperly, e.g. SRQ limit reach and SRQ last wqe reach, which may also occur during normal operation of the software. Currently, the information of these event is printed as a warning, which causes a large amount of printing even during normal use of the application. As a result, the service performance deteriorates. This patch fixes the printing storms by modifying the print level.

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.

2023-09-26RDMA/mlx5: Implement mkeys management via LIFO queueShay Drory
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.

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

git://git.kernel.org/pub/scm/linux/kernel/git/cxl/cxl 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
