cache: Fix for doubled output after reset command
|
|
|
|
Reset command causes a dump of the objects to reset and adds those to
|
|
cache. Yet it ignored if the object in question was already there and up
|
|
to now CMD_RESET was flagged as NFT_CACHE_FULL.
|
|
|
|
Tackle this from two angles: First, reduce cache requirements of reset
|
|
command to the necessary bits which is table cache. This alone would
|
|
suffice if there wasn't interactive mode (and other libnftables users):
|
|
A cache containing the objects to reset might be in place already, so
|
|
add dumped objects to cache only if they don't exist already.
