Android USB Tethering
below info modified from [1]
Required menuconfig prompts/settings according to gentoo wiki and my own configs:
Device Drivers --->
[*] Network device support --->
USB Network Adapters --->
<M> Multi-purpose USB Networking Framework
-M- CDC Ethernet support (smart devices such as cable modems)
<M> CDC EEM support
<M> Host for RNDIS and ActiveSync devices (EXPERIMENTAL)
<M> Simple USB Network Links (CDC Ethernet subset)
[*] Embedded ARM Linux links
note ***
The prompts above frequently change from one kernel version to the next. The above settings were noted as of kernel version 3.8.3-gentoo-r1.
corresponding .config parameters spawned from above settings:
CONFIG_NETDEVICES=y CONFIG_USB_USBNET=m CONFIG_USB_NET_CDCETHER=m CONFIG_USB_NET_CDC_EEM=m CONFIG_USB_NET_RNDIS_HOST=m CONFIG_USB_NET_CDC_SUBSET=m CONFIG_USB_ARMLINUX=y
check config command run against your kernel config file to verify settings
cat .config | grep -E "NETDEVICES|USB_USBNET|USB_NET_CDC_SUBSET|USB_NET_CDCETHER|USB_NET_CDC_EEM|NET_RNDIS_HOST|USB_ARMLINUX"
iptables
-*- Networking support --->
Networking options --->
[*] Network packet filtering framework (Netfilter) --->
Core Netfilter Configuration --->
[*] Netfilter connection tracking support
-*- Netfilter Xtables support (required for ip_tables)
[*] "conntrack" connection tracking match support
[*] "state" match support
IP: Netfilter Configuration --->
[*] IPv4 connection tracking support (required for NAT)
[*] IP tables support (required for filtering/masq/NAT)
[*] Packet filtering

TUN/TAP
CONFIG_TUN
TUN/TAP provides packet reception and transmission for user space programs. It can be viewed as a simple Point-to-Point or Ethernet device, which instead of receiving packets from a physical media, receives them from user space program and instead of sending packets via physical media writes them to the user space program.
When a program opens /dev/net/tun, driver creates and registers corresponding net device tunX or tapX. After a program closed above devices, driver will automatically delete tunXX or tapXX device and all routes corresponding to it.
Required for openvpn.
