Subject: [PATCH] rule: check address family in set collapse
JIRA: https://issues.redhat.com/browse/RHEL-5160
Upstream Status: nftables commit a817ea9655dee
commit a817ea9655dee1915423a802c0133e3611e02b3a
Author: Derek Hageman <hageman@inthat.cloud>

rule: check address family in set collapse
498a5f0c219d added collapsing of set operations in different commands.
However, the logic is currently too relaxed. It is valid to have a
table and set with identical names on different address families.
For example:
table ip a {
set x {
type inet_service;
}
}
table ip6 a {
set x {
type inet_service;
}
}
add element ip a x { 1 }
add element ip a x { 2 }
add element ip6 a x { 2 }
The above currently results in nothing being added to the ip6 family
table due to being collapsed into the ip table add. Prior to
498a5f0c219d the set add would work. The fix is simply to check the
family in addition to the table and set names before allowing a
collapse.

parser_bison: Fix for broken compatibility with older dumps
Commit e6d1d0d611958 ("src: add set element multi-statement
support") changed the order of expressions and other state attached to set
elements are expected in input. This broke parsing of ruleset dumps
created by nft commands prior to that commit.
Restore compatibility by also accepting the old ordering.
