[ Upstream commit 3072f00bba764082fa41b3c3a2a7b013335353d2 ]
In tls_handshake_accept(), a netlink message is allocated using
genlmsg_new(). In the error handling path, genlmsg_cancel() is called
to cancel the message construction, but the message itself is not freed.
This leads to a memory leak.
Fix this by calling nlmsg_free() in the error path after genlmsg_cancel()
to release the allocated memory.
Fixes: 2fd5532044 ("net/handshake: Add a kernel API for requesting a TLSv1.3 handshake")

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.
