It's possible to crash the kernel in several different ways by sending
messages to the SMC_PNETID generic netlink family that are missing the
expected attributes:
- Missing SMC_PNETID_NAME => null pointer dereference when comparing
names.
- Missing SMC_PNETID_ETHNAME => null pointer dereference accessing
smc_pnetentry::ndev.
- Missing SMC_PNETID_IBNAME => null pointer dereference accessing
smc_pnetentry::smcibdev.
- Missing SMC_PNETID_IBPORT => out of bounds array access to
smc_ib_device::pattr[-1].
Fix it by validating that all expected attributes are present and that
SMC_PNETID_IBPORT is nonzero.

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.
