Fork of alistair23 Linux kernel for reMarkable from https://github.com/alistair23/linux
5305d0fe2f
This fixes at least 2 issues I have found with the UDP tunnel filter configuration. The first issue is the fact that the tunnels didn't have any sort of mutual exclusion in place to prevent an update from racing with a user request to add/remove a port. As such you could request to add and remove a port before the port update code had a chance to respond which would result in a very confusing result. To address it I have added 2 changes. First I added the RTNL mutex wrapper around our updating of the pending, port, and filter_index bits. Second I added logic so that we cannot use a port that has a pending deletion since we need to free the space in hardware before we can allow software to reuse it. The second issue addressed is the fact that we were not recording the actual filter index provided to us by the admin queue. As a result we were deleting filters that were not associated with the actual filter we wanted to delete. To fix that I added a filter_index member to the UDP port tracking structure.

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.
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.
