[$] A struct sockaddr sequel

One of the many objectives of the Linux
Kernel Self-Protection Project (KSPP), which just completed ten years of
work, is to ensure that all array references can be bounds-checked,
even in the case of flexible array members, the size of which is not known
at compile time. One of the most challenging flexible array members in the
kernel is not even declared as such. Almost exactly one year ago, LWN looked at the effort to increase safety around
the networking subsystem's heavily used sockaddr structure. One
year later, Kees Cook is still looking for a way to bring this work to a
close.
