[ Upstream commit7133583693] When getting pr_assocstatus and pr_streamstatus by sctp_getsockopt, it doesn't correctly process the case when policy is set with SCTP_PR_SCTP_ALL | SCTP_PR_SCTP_MASK. It even causes a slab-out-of-bounds in sctp_getsockopt_pr_streamstatus(). This patch fixes it by return -EINVAL for this case.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
See Documentation/00-INDEX for a list of what is contained in each file.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
