Linux kernel source tree
9c5f8a1008
In /proc/net/ipv6_route, we have
struct fib6_info {
struct fib6_table *fib6_table;
...
struct fib6_nh fib6_nh[0];
}
struct fib6_nh {
struct fib_nh_common nh_common;
struct rt6_info **rt6i_pcpu;
struct rt6_exception_bucket *rt6i_exception_bucket;
};
struct fib_nh_common {
...
u8 nhc_gw_family;
...
}
The access:
struct fib6_nh *fib6_nh = &rt->fib6_nh;
... fib6_nh->nh_common.nhc_gw_family ...
This patch ensures such an access is handled properly.

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.
