segtree: Check ranges when deleting elementsHEADmaster
Make sure any intervals to delete actually exist, otherwise reject the command. Without this, it is possible to mess up rbtree contents: | # nft list ruleset | table ip t { | set s { | type ipv4_addr | flags interval | auto-merge | elements = { 192.168.1.0-192.168.1.254, 192.168.1.255 } | } | } | # nft delete element t s '{ 192.168.1.0/24 }' | # nft list ruleset | table ip t { | set s { | type ipv4_addr | flags interval | auto-merge | elements = { 192.168.1.255-255.255.255.255 } | } | } Signed-off-by: Phil Sutter <phil@nwl.cc> Acked-by: Pablo Neira Ayuso <pablo@netfilter.org>
