This rule deletion support does not make sense and userspace does not use this. Problem exists since the introduction of chain binding support. 2) rbtree GC worker only collects the elements that have expired. This operation is not destructive, therefore, turn write into read spinlock to avoid datapath contention due to GC worker run. This was not fixed in the recent GC fix batch in the 6.5 cycle. 3) pipapo set backend performs sync GC, therefore, catchall elements must use sync GC queue variant. This bug was introduced in the 6.5 cycle with the recent GC fixes. 4) Stop GC run if memory allocation fails in pipapo set backend, otherwise access to NULL pointer to GC transaction object might occur. This bug was introduced in the 6.5 cycle with the recent GC fixes. 5) rhash GC run uses an iterator that might hit EAGAIN to rewind, triggering double-collection of the same element. This bug was introduced in the 6.5 cycle with the recent GC fixes. 6) Do not permit to remove elements in anonymous sets, this type of sets are populated once and then bound to rules. This fix is similar to the chain binding patch coming first in this batch. API permits since the very beginning but it has no use case from userspace. ==================== Signed-off-by: David S.

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.
