commit 91b0383fef06f20b847fa9e4f0e3054ead0b1a1b upstream. If I'm not mistaken (and I don't think I am), the way in which the dcbnl_ops work is that drivers call dcb_ieee_setapp() and this populates the application table with dynamically allocated struct dcb_app_type entries that are kept in the module-global dcb_app_list. However, nobody keeps exact track of these entries, and although dcb_ieee_delapp() is supposed to remove them, nobody does so when the interface goes away (example: driver unbinds from device). So the dcb_app_list will contain lingering entries with an ifindex that no longer matches any device in dcb_app_lookup(). Reclaim the lost memory by listening for the NETDEV_UNREGISTER event and flushing the app table entries of interfaces that are now gone. In fact something like this used to be done as part of the initial commit (blamed below), but it was done in dcbnl_exit() -> dcb_flushapp(), essentially at module_exit time. That became dead code after commit |

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.
