Daniel Borkmann bc2d4d838f bpf: properly output json for xdp 
After merging net-next branch into master, Stephen asked
to fix up json dump for XDP. Thus, rework the json dump a
bit, such that 'ip -json l' looks as below.

Daniel Borkmann 0b4b35e1e8 json: move json printer to common library 
Move the json printer which is based on json writer into the
iproute2 library, so it can be used by library code and tools
other than ip. Should probably have been done from the beginning
like that given json writer is in the library already anyway.
No functional changes.

Daniel Borkmann a0b5b7cf5c bpf: consolidate dumps to use bpf_dump_prog_info 
Consolidate dump of prog info to use bpf_dump_prog_info() when possible.
Moving forward, we want to have a consistent output for BPF progs when
being dumped. E.g. in cls/act case we used to dump tag as a separate
netlink attribute before we had BPF_OBJ_GET_INFO_BY_FD bpf(2) command.

Move dumping tag into bpf_dump_prog_info() as well, and only dump the
netlink attribute for older kernels. Also, reuse bpf_dump_prog_info()
for XDP case, so we can dump tag and whether program was jited, which
we currently don't show.

Michal Kubecek 460c03f3f3 iplink: double the buffer size also in iplink_get() 
Commit 72b365e8e0 ("libnetlink: Double the dump buffer size") increased
the buffer size for "ip link show" command to 32 KB to handle NICs with
large number of VFs. With "dev" filter, a different code path is taken and
iplink_get() still uses only 16 KB buffer.

The size of 32768 is not very future-proof as NICs supporting 120-128 VFs
are already in use so that single RTM_NEWLINK message in the dump can
exceed 30000 bytes. But it's what rtnl_talk() and rtnl_dump_filter_l() use
so let's be consistent. Once this proves insufficient, all three sizes
should be increased.

Michal Kubecek 6599162b95 iplink: check for message truncation in iplink_get() 
If message length exceeds maxlen argument of rtnl_talk(), it is truncated
to maxlen but unlike in the case of truncation to the length of local
buffer in rtnl_talk(), the caller doesn't get any indication of a problem.

In particular, iplink_get() passes the truncated message on and parsing it
results in various warnings and sometimes even a segfault (observed with
"ip link show dev ..." for a NIC with 125 VFs).

Handle message truncation in iplink_get() the same way as truncation in
rtnl_talk() would be handled: return an error.

William Tu 9a1381d509 gre: add support for ERSPAN tunnel 
The patch adds ERSPAN type II tunnel support. The implementation is
based on the draft at
 https://tools.ietf.org/html/draft-foschiano-erspan-01.

One of the purposes is for Linux box to be able to receive ERSPAN
monitoring traffic sent from the Cisco switch, by creating a ERSPAN
tunnel device. In addition, the patch also adds ERSPAN TX, so traffic
can also be encapsulated into ERSPAN and sent out.

The implementation reuses the key as ERSPAN session ID, and
field 'erspan' as ERSPAN Index fields:
./ip link add dev ers11 type erspan seq key 100 erspan 123 \
		local 172.16.1.200 remote 172.16.1.100

This renames Config to config.mk and includes more Make input.
Now configure generates all the required CFLAGS and LDLIBS for

Also, use pkg-config to test for libelf, rather than using a test
program. This makes it consistent with other libraries.
