iptables: add file lock to prevent concurrent overwrite
...
the kernel can only prevent the concurrency of s/getsockopt, but
iptables will call these interfaces multiple times at a time. We
need to wait for one iptables to complete before executing the second
one, otherwise the data will be overwritten.
iptables flow:
get current iptables entries [1] -> add new entry 2 [1,2] -> set to kernel [1,2]
get current iptables entries [1] -> add new entry 3 [1,3] -> set to kernel [1,3]
entry 2 is lost

iptables: fix the ipv4 mask conversion error
...
the configured mask should be in network byte order, but the logic here
calculates it as host byte order.

system/iptables: Support filter table
...
Add supports for filter table, usage is same as Linux's iptables, including:
- [!] -p/--protocol
- [!] -s/--source -d/--destination
- [!] -i/--in-interface -o/--out-interface
- [!] --sport/--source-port --dport/--destination-port
- [!] --icmp-type
Examples:
> iptables -P FORWARD DROP
> iptables -I INPUT -i eth0 ! -p icmp -j DROP
> iptables -t filter -A FORWARD -p tcp -s 10.0.1.2/24 -d 10.0.3.4/24 -i eth0 -o eth1 --sport 3000:3200 --dport 123:65535 -j ACCEPT
> iptables -t filter -I FORWARD 2 -p icmp ! -s 123.123.123.123 ! -i eth0 -o eth1 ! --icmp-type 255 -j REJECT
> iptables -L
Chain INPUT (policy ACCEPT)
target prot idev odev source destination
DROP !icmp eth0 any anywhere anywhere
Chain FORWARD (policy DROP)
target prot idev odev source destination
ACCEPT tcp eth0 eth1 10.0.1.2/24 10.0.3.4/24 tcp spts:3000:3200 dpts:123:65535
REJECT icmp !eth0 eth1 !123.123.123.123/32 anywhere icmp !type 255
Chain OUTPUT (policy ACCEPT)
target prot idev odev source destination
Note:
- We're dropping dependency of argtable3, since it is difficult to support command like '! -p tcp ! -i eth0'
