Subject: [PATCH nft 0/2] Prevent kernel from adding concatenated ranges if they're not supported
Date: Mon, 13 Apr 2020 21:48:01 +0200 [thread overview]
Message-ID: <cover.1586806931.git.sbrivio@redhat.com> (raw)
This series fixes the nft crash recently reported by Pablo with older
(< 5.6) kernels: use the NFT_SET_CONCAT flag whenever we send a set
including concatenated ranges, so that kernels not supporting them
will not add them altogether, and we won't crash while trying to list
the malformed sets that are added as a result.
Stefano Brivio (2):
include: Resync nf_tables.h cache copy
src: Set NFT_SET_CONCAT flag for sets with concatenated ranges
