Hi,
I installed oflops from:
http://yuba.stanford.edu/git/gitweb.cgi?p=oflops.git;a=summary.
I followed the instruction in the README file (exactly as they were), but
neither the libof_port_stat test nor the libof_packet_in tests/modules
worked.
I tried to run on Ubuntu 11.04 with the reference 1.0 software switch.
I ran the commands as in:
sudo oflops -c lo -d veth1 -d veth3 /usr/local/lib/libof_packet_in.so
And the errors are:
For libof_port_stat:
...
Found unmarked probe.Found unmarked probe.Found unmarked probe.Found
unmarked probe.Found unmarked probe.---- Sending port_stats_requests at
rate 1024 per second for 5 seconds
Found unmarked probe.Found unmarked probe.Found unmarked probe.Found
unmarked probe.Found unmarked probe.Found unmarked probe.Experiment has
10236 packets sent and 0 received -- 1.000000 dropped (i.e., loss = 10236)
with average delay of -nan us.
lo:162:0
And for libof_packet_in:
...
oflops: msg.c:243: get_next_msg: Assertion `(__extension__ ({ register
unsigned short int __v, __x = (unsigned short int) (ofp->length); if
(__builtin_constant_p (__x)) __v = ((unsigned short int) ((((__x) >> 8) &
0xff) | (((__x) & 0xff) << 8))); else __asm__ ("rorw $8, %w0" : "=r" (__v)
: "0" (__x) : "cc"); __v; }))' failed.
When I inspect the stats requests in Wireshark, I can see the port stats
request is missing its body, and ofdatapath complains:
Feb 08 13:44:18|00291|datapath|WARN|stats request type 4 with bad body
length 0
For the packet in I don't know what is causing the error.
What could be wrong?
Allan
