IFLA_MAX is increasing slowly but surely. Some compilers use more than 512 bytes of stack in rtnetlink_rcv_msg() because it calls rtnl_calcit() for RTM_GETLINK message. Use noinline_for_stack attribute to not inline rtnl_calcit(), and directly use nla_for_each_attr_type() (Jakub suggestion) because we only care about IFLA_EXT_MASK at this stage.

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 reStructuredText 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.
