nftables - unable to delete last element of map

[Václav Zindulka <vaclav.zindulka@xxxxxxxxxx>]

Hello,

I've discovered problem with maps in nftables. When I try to remove
last element of the map I get No such file or directory error. I
suppose map can exist without elements since it is default behavior
during creation using commands.

map group_12058 {
  type ipv4_addr : classid
  flags interval
  elements = { 10.13.25.32/29 : 1:b8a1 }
}

nft delete element ip filter group_12058_prio "{ 10.13.25.32/29 }"

Error: Could not process rule: No such file or directory
delete element ip filter group_12058_prio { 10.13.25.32/29 }
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

map group_12064 {
        type ipv4_addr : classid
        flags interval
        elements = { 10.4.28.210 : 1:ae69, 10.4.28.211 : 1:9fe1 }
}

nft delete element ip filter group_12064_prio "{ 10.4.28.210/32 }"

nft delete element ip filter group_12064_prio "{ 10.4.28.211/32 }"
Error: Could not process rule: No such file or directory
delete element ip filter group_12064_prio { 10.4.28.211/32 }
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
