Set the address flags when creating/updating an address with
rtnl_addr_add/rtnl_addr_build_add_request. Before, the flags
were not passed on.
As of now, the flags except IFA_F_NODAD|IFA_F_HOMEADDRESS are ignored by
the kernel. Still pass them on without filtering.

I modified the nl-link-set.c file to be able to set the interface up or
down. I joined the patch.
With the new nl-link-set binary I can set the tap interface down.
I am working with Ubuntu 12.04 LTS 64bits and the libnl and libnl-route
packages built from libnl3-3.2.3 from ubuntu reprositories.

Here are a few things I fixed and that provoked a python error.
I canno't answer to this thread but one solution I found while using
the python binding is to iterate over all and filter via python
http://list-archives.org/2013/09/09/libnl-lists-infradead-org/missing-feature-for-retrieving-cached-
address-objects/f/5031600704
Example:
cache = nlrta.AddressCache()
cache.resync()
for i in cache:
print ("item", i ) # then you can filter here

The message receive callback handler in the netlink api processes
the result object from the python callback. It used PyArg_ParseTuple()
to get the value, but this does not work as intended (see ref [1]).
Instead check the type and convert it accordingly.

The callback functionality only worked for regular Python
functions. With this patch it also allows the callback
to be a class method (bounded or unbounded) as show in
example below.
class test_class(object):
def my_callback(self, msg, arg):
print('handling %s' % str(msg))
s = netlink.core.Socket()
testobj = test_class()
netlink.capi.py_nl_cb_set(cb, netlink.capi.NL_CB_VALID,
netlink.capi.NL_CB_CUSTOM,
test_class.my_callback, testobj)
netlink.capi.py_nl_cb_err(cb, netlink.capi.NL_CB_CUSTOM,
test_class.my_callback, s)

The initial commit adding netlink callback handling also introduced
memory leak issue. The python callback info was stored in an allocated
structure, but that was never freed.
Only exposing nl_cb_alloc() as is. nl_cb_get() is removed as it is
not very useful to use reference counting mechanism. Python uses
that itself internally. To deal properly with Python callback info
the function nl_cb_put() and nl_cb_clone() have a custom wrapper
taking care of Python reference counting.
This commit also adds a Callback python class using the netlink
callback functions.

The application could use the same handler for multiple
nl_cb_type events. This patch stores the nl_cb_type in
the nl_cb struct during the callback. This allows the
application to obtain that information using the new
nl_cb_active_type() function. This way the callback
signature remains as is so existing applications are
not affected.

Newer kernels support conntrack zones, which help to partition the
conntrack table into virtual conntrack tables.
This patch is for adding support for the optional attribute, adds
setters and getters, and adds support for the zone ID in the conntrack
dumper.
An example entry in NL_DUMP_LINE format looks like:
tcp SYN_SENT 10.128.128.99:43354 <-> 10.128.129.20:22 zone 1

Recent kernels support conntrack time stamping, which is a helpful
feature to determine the duration of a flow without building a flow
cache in your user space application, just to keep the 'start' time of
your flow.
Timestamps are recorded with nanosecond resolution once this feature
is enabled.
This patch adds optional support for the CTA_TIMESTAMP, then
modifies the dump routine to write that info in a format similar
to /proc/net/nf_conntrack. This is an example output when using
NL_DUMP_LINE:
udp 10.128.128.28:56836 <-> 10.128.129.255:8612 delta-time 30

Introduced by commit 8026fe2e3a ("link:
Free and realloc af specific data upon rtnl_link_set_family()")
link->l_af_data[link->l_af_ops->ao_family] is freed here but not set to
zero. That leads to double free made by link_free_data->do_foreach_af.
Fix this by setting link->l_af_data[link->l_af_ops->ao_family] to zero
rigth after free.

This small program lists all sockets on the system seen by netlink and serves
as a simple example showing how to alloc an idiag msg cache and dump the
objects in it.
- Inet diag allows users to gather low-level socket information.
- This library provides a higher-level API for creating inetdiag requests (via
idiagnl_connect and idiagnl_send_simple) and parsing the replies (via
idiagnl_msg_parse). A cache is also provided (via idiagnl_msg_alloc_cache).
- Request and message objects provide APIs for accessing and setting the
various properties of each.
- This library also allows the user to parse the inetdiag response attributes
which contain information about traffic class, TOS, congestion, socket
memory info, and more depending on the kernel version used.
- Includes doxygen documentation.
Provide wrapper function for generic netlink library functions. The
genlmsg_parse() function is handled similar to nla_parse_nested() so
it returns tuple with error code and dictionary of parsed attributes.
