David S. Miller a1fa80802c Merge branch 'netlink-extended-attribute-validation'
Johannes Berg says:

====================
netlink: extended attribute validation

This adds further netlink attribute validation:
 * min/max/range validation
 * validation through a custom function pointer

This is useful to
 * reduce boilerplate code in command handling code, if attributes
   are used commonly across different commands
 * get more extended ACK error messages/attribute pointers
 * ensure attributes are valid even when ignored
   (though this might be a problem when converting existing code)

Changes since v1:
 * split off validate_type from type and use that for min/max/range
   and function; this is better because the range is limited to the
   range of s16 and so things like "u16 with minimum value 1" couldn't
   be expressed earlier
 * add macros for this, e.g. NLA_POLICY_MIN(NLA_U16, 1) for the case
   mentioned in the previous bullet

Using this pretty much in all places where applicable in nl80211
reduces the code size there by about 1.8KiB, with just a minimal
code increase in lib/nlattr.o.

README

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.
