The goal of this code change is to implement a mechanism such that it is simple to work with a kernel that is using multiple network namespaces at once. This comes in handy for interacting with vpns where there may be rfc1918 address overlaps, and different policies default routes, name servers and the like. Configuration specific to a network namespace that would ordinarily be stored under /etc/ is stored under /etc/netns/<name>. For example if the dns server configuration is different for your vpn you would create a file /etc/netns/myvpn/resolv.conf. File descriptors that can be used to manipulate a network namespace can be created by opening /var/run/netns/<NAME>. This adds the following commands to iproute. ip netns add NAME ip netns delete NAME ip netns monitor ip netns list ip netns exec NAME cmd .... ip link set DEV netns NAME ip netns exec exists to cater the vast majority of programs that only know how to operate in a single network namespace. ip netns exec changes the default network namespace, creates a new mount namespace, remounts /sys and bind mounts netns specific configuration files to their standard locations.

How to compile this.
--------------------
1. libdbm
arpd needs to have the db4 development libraries. For debian
users this is the package with a name like libdb4.x-dev.
DBM_INCLUDE points to the directory with db_185.h which
is the include file used by arpd to get to the old format Berkely
database routines. Often this is in the db-devel package.
2. make
The makefile will automatically build a Config file which
contains whether or not ATM is available, etc.
3. To make documentation, cd to doc/ directory , then
look at start of Makefile and set correct values for
PAGESIZE=a4 , ie: a4 , letter ... (string)
PAGESPERPAGE=2 , ie: 1 , 2 ... (numeric)
and make there. It assumes, that latex, dvips and psnup
are in your path.
4. This package includes matching sanitized kernel headers because
the build environment may not have up to date versions. See Makefile
if you have special requirements and need to point at different
kernel include files.
