For all string attributes for which we don't currently accept the element as input, we only use it as output, set the string length to RDMA_NLDEV_ATTR_EMPTY_STRING which is defined as 1. That way we will only accept a null string for that element. This will prevent someone from writing a new input routine that uses the element without also updating the policy to have a valid value. Also while there, make sure the existing entries that are valid have the correct policy, if not, correct the policy. Remove unnecessary checks for nla_strlcpy() overflow once the policy has been set correctly. Signed-off-by: Doug Ledford <dledford@redhat.com> Signed-off-by: Jason Gunthorpe <jgg@mellanox.com>
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.
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.
