Mirsad Goran Todorovac 7d6ceeb187 af_unix: selftest: Fix the size of the parameter to connect()
Adjust size parameter in connect() to match the type of the parameter, to
fix "No such file or directory" error in selftests/net/af_unix/
test_oob_unix.c:127.

The existing code happens to work provided that the autogenerated pathname
is shorter than sizeof (struct sockaddr), which is why it hasn't been
noticed earlier.

Visible from the trace excerpt:

bind(3, {sa_family=AF_UNIX, sun_path="unix_oob_453059"}, 110) = 0
clone(child_stack=NULL, flags=CLONE_CHILD_CLEARTID|CLONE_CHILD_SETTID|SIGCHLD, child_tidptr=0x7fa6a6577a10) = 453060
[pid <child>] connect(6, {sa_family=AF_UNIX, sun_path="unix_oob_45305"}, 16) = -1 ENOENT (No such file or directory)

BUG: The filename is trimmed to sizeof (struct sockaddr).

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.
