Matthias Radestock b5df59660f don't set pcap timeout, to prevent cpu churn 
pcap timeouts are a mystery. Setting the timeout to -1 used to reduce
latency, but that was before we started setting immediate mode. And it
turns out that with that timeout, pcap chews through a lot of CPU
polling its file descriptor, checking timers, etc.

With no timeout set an idle weave is completely idle - no system calls
at all.

Fixes #80

Bryan Boreham 7815446032 Merge pull request #78 from zettio/77_eliminate_connection_maker_tick 
eliminate periodic 'tick' in connection_maker
 2014-09-23 10:58:25 +01:00
Matthias Radestock eecaa567fc eliminate periodic 'tick' in connection_maker 
checkStateAndAttemptConnections already performs a full scan of all
potential targets, from which we can easily determine the nearest
future time (or, rather, its duration from now) on which an attempt is
due.

We also need to kick the ConnectionMaker into action when we receive a
topology update containing new connections.

Bryan Boreham c48ae19c55 Tidy up messages; ensure errors to to stderr 2014-09-18 11:47:47 +01:00
Bryan Boreham a75a0d8709 If and only if network setup because the container died, say so. 
This involves capturing stderr output from all the 'ip' commands so we
can hide that output if we see the process died, or show it to the user
if the process didn't die, in which case we don't know why we failed.

Bryan Boreham bfd5007339 Don't test if symlink exists before 'rm -f' 
When the symlink's target doesn't exist, '[ -f' is false, so the symlink doesn't get removed.
Since we do always want it to be removed, just call 'rm -f' anyway, which won't complain
if the file doesn't exist.

David Wragg 12b969004e Filter outbound packets in the kernel 
It turns out that under Linux, libpcap implements the SetDirection
filtering in userspace, causing some spurious wake ups of the packet
capture thread.  So set a BPF filter to discard outbound packets inside
the kernel.
