Hi Linus,

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.

Thanks,
Jason

  RDMA/rxe: Fix rxe_cq_post (2023-06-14 14:12:43 -0300)

----------------------------------------------------------------
v6.4 second rc RDMA pull request

Many rc bug fixes:

- 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
