Subject: [PATCH] src: Set NFT_SET_CONCAT flag for sets with concatenated
ranges
Bugzilla: https://bugzilla.redhat.com/show_bug.cgi?id=1854532
Upstream Status: nftables commit 09441b5e92cee
commit 09441b5e92ceea60198a35cd657904fa7a10ee54
Author: Stefano Brivio <sbrivio@redhat.com>

src: Set NFT_SET_CONCAT flag for sets with concatenated ranges
Pablo reports that nft, after commit 8ac2f3b2fca3 ("src: Add support
for concatenated set ranges"), crashes with older kernels (< 5.6)
without support for concatenated set ranges: those sets will be sent
to the kernel, which adds them without notion of the fact that
different concatenated fields are actually included, and nft crashes
while trying to list this kind of malformed concatenation.
Use the NFT_SET_CONCAT flag introduced by kernel commit ef516e8625dd
("netfilter: nf_tables: reintroduce the NFT_SET_CONCAT flag") when
sets including concatenated ranges are sent to the kernel, so that
older kernels (with no knowledge of this flag itself) will refuse set
creation.
Note that, in expr_evaluate_set(), we have to check for the presence
of the flag, also on empty sets that might carry it in context data,
and actually set it in the actual set flags.
