I found recently that, if I disabled address promotion in the kernel, that ip addr flush dev <dev> would fail with an EADDRNOTAVAIL errno (though the flush operation would in fact flush all addresses from an interface properly) Whats happening is that, if I add a primary and multiple secondary addresses to an interface, the flush operation first ennumerates them all with a GETADDR | DUMP operation, then sends a delete request for each address. But the kernel, having promotion disabled, deletes all secondary addresses when the primary is removed. That means, that several delete requests may still be pending in the netlink request for addresses that have been removed on our behalf, resulting in EADDRNOTAVAIL return codes. It seems the simplest thing to do is to understand that EADDRUNAVAIL isn't a fatal outcome on a flush operation, as it just indicates that an address which you want to remove is already removed, so it can safely be ignored.

This is a set of utilities for Linux networking.

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 Berkeley
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.
