Bug ID: 1409
Summary: nft manpage makes confusing reference to logical
operators
Product: nftables
Version: unspecified
Hardware: All
OS: All
Status: NEW
Severity: enhancement
Priority: P5
Component: nft
Assignee: pablo at netfilter.org
Reporter: cheetah-netfilter at fastcat.org
The nft manpage / docs say:
> Expressions can be combined using binary, logical, relational and other types of
> expressions to form complex or relational (match) expressions
http://git.netfilter.org/nftables/tree/doc/nft.txt#n680
However it's not clear if logical combinations are actually possible?
https://bugzilla.netfilter.org/show_bug.cgi?id=1202#c1 explicitly states that
disjunctions are definitely not supported, so logical OR, and XOR are right
out, and given that I'd say NAND almost certainly is too. The only combining
operator for matches is AND.
Also, rummaging through the grammar file seems to confirm that there are only
_bitwise_ operators.
