| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The overlapping process.* tapsets are now separated. Those probe points documented in stapprobes(3stap) remain the same. Those that were formerly in stapprobes.process(3stap) have been renamed to kprocess, to reflect their kernel perspective on processes.

Mainly, it's possible to get the iphdr and tcphdr from a sk_buff structure. As a consequence, a TCP probe called tcp.receive() was created and is probed every time a TCP packet is received, and a lot of useful fields is available, as the TCP flags. Also a small example that works like tcpdump for received TCP packets was created. This patch was tested on x86 and ppc machines, on 2.6.18 kernel and also on mainline one.

The root problem in this case was that dwarf_attr didn't find the type attribute, and that failure wasn't immediately caught. Now that result is checked so we can provide a proper error message. While I'm at it, changing that lookup to dwarf_attr_integrate is enough to make the $return value usable again, at least for the reported test case.
