[PATCH nft v2 0/2] Fix evaluation of anonymous sets with concatenated ranges

[Stefano Brivio <sbrivio@redhat.com>]

As reported by both Pablo and Phil, trying to add an anonymous set
containing a concatenated range would fail:

  # nft add rule x y ip saddr . tcp dport { 192.168.2.1 . 20-30 } accept
  BUG: invalid range expression type concat
  nft: expression.c:1160: range_expr_value_low: Assertion `0' failed.
  Aborted

  # nft add rule t c ip daddr . tcp dport '{ 10.0.0.0/8 . 10-23, 192.168.1.1-192.168.3.8 . 80-443 } accept'
  BUG: invalid range expression type concat
  nft: expression.c:1296: range_expr_value_low: Assertion `0' failed.

Patch 1/2 fixes this, and 2/2 enables a test for it in inet/sets.t.

v2: Don't add anonymous sets to cache, fix leak for object maps, and
    use existing test rule instead of adding a new test

Stefano Brivio (2):
  evaluate: Perform set evaluation on implicitly declared (anonymous)
    sets
  tests: py: Enable anonymous set rule with concatenated ranges in
    inet/sets.t
