[PATCH nft 0/4] fix list chain x y with anonymous chains

[Pablo Neira Ayuso <pablo@xxxxxxxxxxxxx>]

Hi,

Patches 1 to 3 are cache preparation work.

Then, patch 4 fixes listing

 # nft list chain x y
 table ip x {
        chain y {
                jump {
                        accept
                }
        }
 }

This is broken in the nftables 1.0.1 release.

See https://bugzilla.netfilter.org/show_bug.cgi?id=1577

Pablo Neira Ayuso (4):
  src: do not use the nft_cache_filter object from mnl.c
  cache: do not set error code twice
  cache: add helper function to fill up the rule cache
  src: 'nft list chain' prints anonymous chains correctly
