[PATCH v5 3/9] pseries/plpks: fix length types for wrapping operations

[sashiko-bot at kernel.org]

> The object wrapping and unwrapping HCALLs use 64-bit length values, but
> plpks_wrap_object() and plpks_unwrap_object() currently use u32 for the
> input and output length parameters.
> 
> Use u64 for the length parameters to match the underlying HCALL interfaces,
> and update the PKWM consumer accordingly. Validate input lengths against
> the HCALL-defined limits before calculating output buffer sizes.
> 
> Fixes: 133aa79e211d ("pseries/plpks: add HCALLs for PowerVM Key Wrapping Module")
> Fixes: c99fcb0d735b ("keys/trusted_keys: establish PKWM as a trusted source")
> Cc: stable at vger.kernel.org # 7.0
