Consequently, calls to nft_set_attr_get_u32() in netlink.c fail because that routine (in libnftables) dereferences a null pointer returned by nft_set_attr_get(). I fixed it in nft by calling nft_set_attr_is_set() to test for the attribute's existence. It could also be fixed in the kernel by unconditionally sending the FLAGS attribute even if it is zero. Also it might be worth putting some more error checking for missing attributes (do any others get conditionally left out?) -- Configure bugmail: htt...
