[ Upstream commit8080b462b6] 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.

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.
