Jakub Kicinski 35b71a34ad net/tls: don't leak partially sent record in device mode
David reports that tls triggers warnings related to
sk->sk_forward_alloc not being zero at destruction time:

WARNING: CPU: 5 PID: 6831 at net/core/stream.c:206 sk_stream_kill_queues+0x103/0x110
WARNING: CPU: 5 PID: 6831 at net/ipv4/af_inet.c:160 inet_sock_destruct+0x15b/0x170

When sender fills up the write buffer and dies from
SIGPIPE.  This is due to the device implementation
not cleaning up the partially_sent_record.

This is because commit a42055e8d2 ("net/tls: Add support for async encryption of records for performance")
moved the partial record cleanup to the SW-only path.

Fixes: a42055e8d2 ("net/tls: Add support for async encryption of records for performance")

README

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.
