Pablo Neira AyusoandGreg Kroah-Hartman 6ac03e6ddd netfilter: nft_set_rbtree: overlap detection with element re-addition after deletion
[ Upstream commit babc3dc952 ]

This patch fixes spurious EEXIST errors.

Extend d2df92e98a ("netfilter: nft_set_rbtree: handle element
re-addition after deletion") to deal with elements with same end flags
in the same transation.

Reset the overlap flag as described by 7c84d41416 ("netfilter:
nft_set_rbtree: Detect partial overlaps on insertion").

Fixes: 7c84d41416 ("netfilter: nft_set_rbtree: Detect partial overlaps on insertion")
Fixes: d2df92e98a ("netfilter: nft_set_rbtree: handle element re-addition after deletion")

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.
