Roberto Bergantinos Corpas 65afa69581 sunrpc: expiry_time should be seconds not timeval
commit 3d96208c30f84d6edf9ab4fac813306ac0d20c10 upstream.

When upcalling gssproxy, cache_head.expiry_time is set as a
timeval, not seconds since boot. As such, RPC cache expiry
logic will not clean expired objects created under
auth.rpcsec.context cache.

This has proven to cause kernel memory leaks on field. Using
64 bit variants of getboottime/timespec

Expiration times have worked this way since 2010's c5b29f885a "sunrpc:
use seconds since boot in expiry cache".  The gssproxy code introduced
in 2012 added gss_proxy_save_rsc and introduced the bug.  That's a while
for this to lurk, but it required a bit of an extreme case to make it
obvious.

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.
