      IB/mlx5: Fix cleanup order on unload · 42cea83f
      由 Mark Bloch 提交于 
      On load we create private CQ/QP/PD in order to be used by UMR, we create
those resources after we register ourself as an IB device, and we destroy
them after we unregister as an IB device. This was changed by commit
16c1975f ("IB/mlx5: Create profile infrastructure to add and remove
stages") which moved the destruction before we unregistration. This
allowed to trigger an invalid memory access when unloading mlx5_ib while
there are open resources:

We restore the original behavior by breaking the UMR stage into two parts,

      IB/mlx5: Maintain a single emergency page · c44ef998
      由 Ilya Lesokhin 提交于 
      The mlx5 driver needs to be able to issue invalidation to ODP MRs
even if it cannot allocate memory. To this end it preallocates
emergency pages to use when the situation arises.

This flow should be extremely rare enough, that we don't need
to worry about contention and therefore a single emergency page
is good enough.

      The failure in rereg_mr flow caused to set garbage value (error value)
into mr->umem pointer. This pointer is accessed at the release stage
and it causes to the following crash.

There is not enough to simply change umem to point to NULL, because the
MR struct is needed to be accessed during MR deregistration phase, so
delay kfree too.

      RDMA/mlx5: Fix integer overflow while resizing CQ · 28e9091e
      由 Leon Romanovsky 提交于 
      The user can provide very large cqe_size which will cause to integer
overflow as it can be seen in the following UBSAN warning:

      由 Doug Ledford 提交于 
      The original commit of this patch has a munged log message that is
missing several of the tags the original author intended to be on the
patch.  This was due to patchworks misinterpreting a cut-n-paste
separator line as an end of message line and munging the mbox that was
used to import the patch:

https://patchwork.kernel.org/patch/10264089/

The original patch will be reapplied with a fixed commit message so the
proper tags are applied.

This reverts commit aa0de36a.
