Subject: get_node_kv: unpack result from pmxcfs
X-Git-Url: https://git.proxmox.com/?p=pve-cluster.git;a=commitdiff_plain;h=14000cd7140b2bb9ea0faa8ce9d686d9c72ff26f

get_node_kv: unpack result from pmxcfs

in 'broadcast_node_kv' we send the status and make sure its always
a scalar so it gets send as a null terminated string via pack(Z*)
when we get it back from pmxcfs we have to unpack(Z*) again, or
we get a string with a trailing '\0'
