96f17ce146 bonding: API to create/enslave/release
Although it has been possible to create bonding devices, enslave and
release using the regular link API. The added API simplifies usage
and hides some of the compatibility logic.

F.e. enslave() and release() will both verify that the master assignment
has in fact been changed and return -NLE_OPNOTSUPP if it did not.

Also the API will make sure to use RTM_NEWLINK or RTM_SETLINK depending
on what is availble.

Examples are provided in src/ as nl-link-enslave.c and nl-link-release.c

5151cbc2f6 link: Eat ACK followed by RTM_NEWLINK when requesting single link
When requesting a single link with RTM_GETLINK (no dump) the
RTM_NEWLINK carrying the answer will be followed by an ACK
we have to wait for.

db6de563fe fix license of lib/route/pktloc.c
As Jan Engelhardt pointed out, pktloc.c is currently licenses under the GPL
rather than the LGPL. This is a result of its previous existance in src/
which is GPL licensed. I missed to change its license when moving it to
lib/. Since I am the only contributor to the code, I am changing the license
hereby.

f1d9e9d52d 64bit unaligned access
This patch fixes an unaligned access for IPv6.  On systems with strict alignment requirements, the unaligned access will either result in garbage data or a crash.

16d38a49d1 Use 'link type' instead of 'link info type'
The term 'link type' is much more easier to understand than 'link info type'

d44c31da5f addr: store link object and provide rtnl_addr_get()
stores rtnl_link object in address if cache is availble. Provide access
via rtnl_addr_get_link() and rtnl_addr_set_link().

Add rtnl_addr_get() which searches a address cache for an address
matching ifindex and local address.

cb6a089d80 Adding rule with "From" option doesn't work
OK i found the bug, is is the patch !!

Can someone push it into the git tree ?
Regards,

Romary Sonrier

=========================
My analysis:

I guess that the pay load is *struct fib_rule_hdr*
struct fib_rule_hdr {
__u8 family;
__u8 dst_len;
__u8 src_len;
__u8 tos;

__u8 table;
__u8 res1; /* reserved */
__u8 res2; /* reserved */
__u8 action;

__u32 flags;
};

> [PAYLOAD] 12 octets
> 02 00 00 00 0a 00 00 01 00 00 00 00 ............
so

family = 02 , fine

table = 10, fine
but
src_len =0 !!!! should be 32

daefa76959 Provide rtnl_tc_get_link() and fix link refcnt
Adds rtnl_tc_get_link() returning the link associated with a tc
object.

Don't clone link associated with tc object when cloning the tc
object, refer to same link instead and bump refcnt.

Fix refcnt leak when assigning link in msg parser.

96bc6d6f66 Improve rtnl_link_change() behaviour
- avoid unncessary name change requests
    The kernel does not check if the specified IFNAME is different
    from the current name. It assumes that if IFNAME and ifindex
    are both specified, a name change is requested. Therefore avoid
    specyfing IFNAME if ifindex is provided and original and new
    name are identical.
- move link building to own function (to allow link add later on)
- error if immutable changes have been made
- better documentation

48d543cfdf API to issue direct GET requests to the kernel
Provide nl_pickup() to pick up an answer from a netlink request and parse
it using the supplied parser.

Add rtnl_link_get_kernel() which sends an RTM_GETLINK to the kernel to
fetch a single link directly from the kernel. This can be faster than
dumping the whole table, especially if lots of links are configured.

747b892c91 Qdisc API improvements and documentation
Deprecated the functions rtnl_qdisc_change() and
rtnl_qdisc_build_change_request() for their lack of being able to
specify flags. The new functions rtnl_qdisc_update() and
rtnl_qdisc_build_update_request() may be used instead. The old
functions are still available though. However, rtnl_qdisc_update()
no longer implies NLM_F_REPLACE, it has to specified implicitely
to allow updating a qdisc without risking to replace another qdisc.

Included detailed documentation of qdisc addition/update/deletion.

Introduced APPBUG() macro to let application developer know of
API abuse.

e4b507e290 Deprecate rtnl_qdisc_foreach_child() and rtnl_qdisc_foreach_cls()
Their usage is not completely safe, it is not possible to handle
the out of memory situation of the allocate filter. It is very
unlikely for this to cause any problem though.

The functions are still accessible but gcc will warn about their
deprecation.

8eb5b5532e Unified TC API
Finally got rid of all the qdisc/class/cls code duplication in
the tc module API. The API takes care of allocation/freeing the
tc object specific data.
