Add support for MPLS labels in nexthop specification. Specifically, the
'as' keyword specifies the MPLS label stack and if the route address
family is MPLS then the nexthop via is added as a route via instead of
a gateway (subtle differences introduced for MPLS).

Commit 3cb28534d34392ceec4adead0cfa97039796ccb7 enables building
of cli always as part of `make check`. As cli previously always
included <dlfcn.h>, this broke tests for building with toolchains
that don't support dynamic library loading.
Add a configure check and disable dlopen() based on whether
<dlfcn.h> is available.

uClibc doesn't implement strerror_l() and thus libnl starting from
3.2.29 couldn't be compiled with it any longer.
To work-around that problem we'll just do a check on strerror_l()
availability during configuration and if it's not there just fall back
to locale-less strerror().

It would be desirable not to include kernel headers in our public
libnl3 headers. As a test, remove all those includes, and fix
compilation by explicitly including the kernel headers where needed.
In some cases, that requires forward declaration for kernel
structures, as we use them as part of our own headers.
Realistically, we cannot drop those includes as it probalby breaks
compilation for users that expect to get a certain kernel header
when including a libnl3 header. So, this will not be done and the
includes will be restored in the next commit.
Do this step to show how it would be and to verify that we could
build with such a change. The reason not to do this is backward
compatibility (at compile-time).

The result is basically the same, but I feel that __RTNL_LINK_STATS_MAX
is an internal variable that shouldn't be used. Thus, let's iterate
instead until <= MAX.

Use __RTNL_LINK_STATS_MAX instead of RTNL_LINK_STATS_MAX when iterating
over all rtnl link stat counters. Otherwise, the last stat counter will
always be missing, as RTNL_LINK_STATS_MAX is the value of the last valid
index.

glibc provides two versions of strerror_r(), which
can be chosen between using feature test macros
_GNU_SOURCE and _POSIX_C_SOURCE. libnl is built using
the former, hence we get the glibc special version,
and all code so far has been written for this.
Other C libraries like musl on the other hand only try
to be posix compliant, and only ever provide the posix
version of strerror_r(), which has a different signature.
Uses in libnl hence generally cause printf() of an *int*
with a *string format* specifier for that reason.
Additionally, strerror_r() has been deprecated:
http://austingroupbugs.net/view.php?id=655
Switch to using strerror_l().

Both link and neighbor cache support specify multiple groups (nl_af_group),
but the alloc_cache functions for both do not set the NL_CACHE_AF_ITER
flag before populating the cache so only the first group is used by
default. This patch adds an API to pass in flags to make that happen
and updates the nl-neigh-list command to make use of it.

Including linux/if.h in netlink/route/link.h causes issues
in cases where libnl is used in conjuntion with other third
party libraries that include net/if.h. Seems to be a long
checkered history of symbol collisions between these two
files. As it turns out, including linux/if.h from within
netlink/route/link.h is actually unecessary. I resurrected
a forgotten path from this thread:
http://lists.infradead.org/pipermail/libnl/2012-April/000525.html
By removing the include as the patch suggests we can get
around the nuissance of the symbol collisions.

These values mirror TCP_* socket states from 'netinit/tcp.h'.
There is no good reason to expose a copy of those values.
User space should use the original values (if they care).
The only value that is actually useful is IDIAGNL_SS_ALL.

libnl3 contains a private copy of some kernel header files.
Normally, users are expected to install libnl and specify
-I$PREFIX/include/libnl3 as include path. As the private kernel
header files are not installed, this works fine.
However, it can be convenient to build against the libnl source
directory, without installing libnl. In this case, the private kernel
header files shaddow the system provided ones. This is undesired.
Move these files to a different directory to avoid this clash.

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.
