[Openswan dev] bug report for 2.6.10-1 on OpenWRT Kamikaze 7.09: erratic ping, terrible performance

[starlight at binnacle.cx]

The bug tracking system wouldn't let me create an account,
so I gave up.

Running on OpenWRT on WRT54G v2.0 and WRT54GS v2.1

Just upgraded from White Russian 0.9 to Kamikaze 7.09.

Was running White Russian packaged OpenSWAN 2.4.8rc1, upgraded 
to OpenSWAN 2.4.10-1 on Kamikaze.

With the same exact 'ipsec.conf', ICMP echos times have suddenly 
become erratic.  On old version 'ping' gave solid and consistent 
values in the range of 14-17 milliseconds.  Now it looks like as 
staircase running from 15 to 100 milliseconds.

Also had installed OpenSWAN direct release 2.4.9-7 on White 
Russian router just prior to building the Kamikaze router.  Saw 
same problem.

Also getting terrible performance from a 'curl' HTTP file 
upload.  So bad I may go back to the original configuration. 
Maybe will try Kamikaze provided OpenSWAN build.

A sample 'ping' output (run from a CentOS 4.5 Athlon 4800+) 
follows.
