commit 15ccbf685222274f5add1387af58c2a41a95f81e upstream.
When the receiver variables (aka "session") are initialized, then they are
added to the list of sessions before the timer is set up. A RCU protected
reader could therefore find the entry and run mod_setup before
batadv_tp_init_recv() finished the timer initialization.
The same is true for batadv_tp_start(), which must first initialize the
finish_work and the test_length to avoid a similar problem.

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.
See Documentation/00-INDEX for a list of what is contained in each file.
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.
