[DTrace-devel] [PATCH v2 0/2] udp: new provider

[Alan Maguire]

This series adds UDP provider support, where the probes are
implemented via underlying raw fbt probes.

Probes are

udp:::send
udp:::receive

Arguemnts args[0-4] are

pktinfo_t *, csinfo_t *, ipinfo_t *, udpsinfo_t *, udpinfo_t *

Patch 1 implements the provider.

Patch 2 fixes up the remote IPv4 UDP test.

To work on UEK6, the following not-yet-landed patches are required

cg: fix offset for > 8 bit bitfields in dt_cg_ctf_offsetof()
Convert ip6_finish_output to rawfbt

Changes since v1:

- squashed dlibs, test.x and provider test changes into patch 1
  (Eugene)
- switched to rawfbt due to issues seen on UEK6 and risks with static
  functions (Eugene)

Alan Maguire (2):

  test/unittest/udp: enable IPv4 remote udp test
