Drop unnecessary table rewrite in GetRules() after 3e042f7 (#219) 2023-03-16 12:38:54 +01:00
xiaoff 1aef2ba20e
Fix: add NFTA_RULE_COMPAT attribute (#207) 
xt_matches or xt_targets like xt_tcpudp may have specific compat policy and
if not set flush rule will error with EINVAL
according to https://elixir.bootlin.com/linux/v3.13/source/net/netfilter/x_tables.c#L563
