Vinay Kumar Yadav 14d755a481 chelsio/chtls: fix memory leaks caused by a race
[ Upstream commit 8080b462b6aa856ae05ea010441a702599e579f2 ]

race between user context and softirq causing memleak,
consider the call sequence scenario

chtls_setkey()         //user context
chtls_peer_close()
chtls_abort_req_rss()
chtls_setkey()         //user context

work request skb queued in chtls_setkey() won't be freed
because resources are already cleaned for this connection,
fix it by not queuing work request while socket is closing.

v1->v2:
- fix W=1 warning.

v2->v3:
- separate it out from another memleak fix.

Fixes: cc35c88ae4 ("crypto : chtls - CPL handler definition")

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.
