table: support for the table owner flag
Add new flag to allow userspace process to own tables: Tables that have
an owner can only be updated/destroyed by the owner. The table is
destroyed either if the owner process calls nft_ctx_free() or owner
process is terminated (implicit table release).
The ruleset listing includes the program name that owns the table:
nft> list ruleset
table ip x { # progname nft
flags owner
chain y {
type filter hook input priority filter; policy accept;
counter packets 1 bytes 309
}
}
Original code to pretty print the netlink portID to program name has
been extracted from the conntrack userspace utility.
