Hi everyone,
Looking at mailing list archives there has been much talk of this print
in the past, given the fact that this check/print is surrounded by an
#ifdef TCP_DEBUG
#ifdef TCP_DEBUG
if (net_ratelimit()) {
struct inet_sock *inet = inet_sk(sk);
printk(KERN_DEBUG "TCP: Treason uncloaked! Peer
%u.%u.%u.%u:%u/%u shrinks window %u:%u. Repaired.\n",
NIPQUAD(inet->daddr), htons(inet->dport),
inet->num, tp->snd_una, tp->snd_nxt);
}
#endif
I thought that maybe it's time to either set TCP_DEBUG to 0 or
alternatively allow an admin to toggle the printing of this message
off/on? On a few busy web servers running usually latest versions of
2.6 I have this message displaying hundreds (if not more) times a day,
completely clogging the kernel log and making it harder to see if there
are more interesting messages being printed. TCP_DEBUG is being used
in one more place that may also not require it anymore and or have it
always enabled.
So, is it time to disable this print altogether? Is it time to allow an
admin to toggle printing of this thing off?
Thanks for your time
