[ Upstream commit29bacb096d] xs_tcp_tls_setup_socket() creates a temporary "lower" rpc_clnt with rpc_create() to drive the inner TLS handshake, then waits for XPRT_LOCKED on its xprt with TASK_KILLABLE so a stuck handshake can be aborted by signal. When the wait is interrupted, the function jumps to out_unlock without releasing lower_clnt. The success path and the out_close error path both call rpc_shutdown_client(lower_clnt); only the killed-wait path skips it, leaking the clnt and its underlying xprt. Call rpc_shutdown_client() on this path before joining out_unlock. xprt_release_write() is not needed here because XPRT_LOCKED was never acquired.

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.
