When we tell kernel to dump filters from root (ffff:ffff), those filters on ingress (ffff:0000) are matched, but their true parents must be dumped as they are. However, kernel dumps just whatever we tell it, that is either ffff:ffff or ffff:0000: $ nl-cls-list --dev=dummy0 --parent=root cls basic dev dummy0 id none parent root prio 49152 protocol ip match-all cls basic dev dummy0 id :1 parent root prio 49152 protocol ip match-all $ nl-cls-list --dev=dummy0 --parent=ffff: cls basic dev dummy0 id none parent ffff: prio 49152 protocol ip match-all cls basic dev dummy0 id :1 parent ffff: prio 49152 protocol ip match-all This is confusing and misleading, more importantly this is a regression since 4.15, so the old behavior must be restored. And, when tc filters are installed on a tc class, the parent should be the classid, rather than the qdisc handle. Commit |

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.
