nuqneH,

Ok, i (at least i think so) solved my OOB problem.
Short summary - how does OOB work in TDS 4:
Cancel message has no data, just header:

0x06 "Cancel" message
0x01 the last and only fragment
0x00 \ message size is 8, nbo
0x08 /
0x00 \ channel is 0
0x00 /
0x01 pktnum is 1
0x00 window is 0, and _this byte_ is sent as OOB so you need
setsockopt(..,SO_OOBINLINE..) to read it.

The most funny thing is it all works if you send the whole message without
OOB.

I expect fwtk proxy for MS SQL to be finished this week.
