(OT) rfc1948 question
...to tcp_syncache.c
I did not managed to find any rfc1948 related info in CVS log for this
file. Maybe I just missed it.
Then I just looked into my copy of tcp_syncache.c and found that:
;------------------Begin clipboard----------------------------
if (tcp_syncookies)
sc->sc_iss = syncookie_generate(sc);
else
sc->sc_iss = arc4random();
;--------------------End clipboard----------------------------
Is it the place where synack iss is generated? If yes, then why
net.inet.tcp.syncookies sysctl is turned on by default? Is arc4random
not enough random...
