[adsquaired at gmail.com]

Package: nftables
Version: 0.8.1-1
Severity: normal

Dear Maintainer,

   * Observed while functionality testing
   * flush a map before restoring from file. 

     ** nft list table test > backup
     ** flush the maps
     ** nft -f backup
 
   * Example below - valid map exists

nft list map test test_nat - (valid map exists)
--------
table ip test {
	map testt_nat {
		type ipv4_addr . inet_service : ipv4_addr
		elements = { x.x.x.5 . domain : 8.8.4.4,
			     x.x.x.6 . domain : 8.8.8.8 }
	}
-------   
   * Error

nft flush map test test_nat - (according to man page this should work)
-------
Error: Could not process rule: Invalid argument
flush map test test_nat
^^^^^^^^^^^^^^^^^^^^^^^^^^
-------
   * Expected outcome: remove the elements from the map.
