I am still having trouble with the table (as I had with the original mail, which was just too long - as is the table). The bottom lines are: 0) Drop all test cases with the sysctl turned off (they should dtrt also w/o the sysctl). It should be a SADB policy && socket option decision (depending on direction). 1) there is a problem in _syncache_add leading to the wrong behaviour in situations in respond. 2) there is another problem I haven't looked at where to say it is, basically related to the way we decide to treat (0) (but also in the other direction) 3) there is a problem of not properly checking an error case in tcp_subr.c at one point but would be void if (0/2) was done right in both directions. If you can wait till early next week I might have a patch that cleans parts of this up in general and we can go from there? /bz -- Bjoern A. Zeeb You have to have visions!
