vxlan: allow for dynamic source ip selection (FS#3426)
By setting 'auto', the zero address or the empty string as source
address (option ipaddr, option ip6addr), vxlan will choose one
dynamically. This helps in setups where a wan ip or prefix changes.

This corresponse to setting up an vxlan tunnel with:

proto vxlan6:
    # ip link add vx0 type vxlan id ID local :: ...
proto vxlan:
    # ip link add vx0 type vxlan id ID local 0.0.0.0 ...

While it is possible to not specify a source ip at all, the kernel will
default to setting up a ipv4 tunnel. The kernel will take any hint from
source and peer ips to figure out, what tunnel type to use. To make sure
we setup an ipv6 tunnel for proto vxlan6, this workaround is needed.

This will not change the behaviour of currently working configurations.
However this will allow former broken configurations, namely those not
specifying both a source address and tunnel interface, to setup a
tunnel interface. Previously those configurations weren't reporting an
error and were stueck in a setup loop like in Bug FS#3426.

This change lifts the currently very strict behaviour and should fix the
following bug:

How to make it

Minimum requirements

Linux with case sensitive
2G DDR2 RAM
2 CPU Cores (AMD64, 1.4Ghz)
25G disk space left
Has access to both ChinaNet & Internet

Install the necessary packages (for Ubuntu user)

sudo apt-get update -y
sudo apt-get full-upgrade -y
sudo apt-get install -y build-essential asciidoc binutils bzip2 gawk gettext git libncurses5-dev libz-dev patch unzip zlib1g-dev lib32gcc1 libc6-dev-i386 subversion flex uglifyjs git-core gcc-multilib g++-multilib p7zip p7zip-full msmtp libssl-dev texinfo libreadline-dev libglib2.0-dev xmlto qemu-utils upx libelf-dev autoconf automake libtool autopoint ccache curl wget vim nano python python3 python-pip python3-pip python-ply python3-ply haveged lrzsz device-tree-compiler scons antlr3 gperf intltool rsync

For mainland China & Ubuntu(16.04+) user, you may run the following command to setup quickly:

sudo bash -c "bash <(curl -s https://build-scripts.project-openwrt.eu.org/init_build_environment.sh)"

Clone the source

git clone -b openwrt-18.06 --single-branch https://github.com/project-openwrt/openwrt && cd openwrt
./scripts/feeds update -a && ./scripts/feeds install -a

For developer, you may use openwrt-18.06-dev branch instead of openwrt-18.06.

Configure your firmware

make menuconfig

Make it

make -j1 V=s

Tips

You'd better not use root to make it, or you may be not able to use.
Default login address: 192.168.1.1, username is root and password is password.
