View Full Version : strange dmesg output

March 17th, 2009, 02:04 PM
I have a screenlet that outputs dmesg on my desktop every once in a while. Today, after a period of inactivity, I saw my desktop, and found this strange message:

TCP: Treason uncloaked! Peer shrinks window 477191629:477191634. Repaired.

repeated some times...Sounds serious, but as everything seems to keep working as it should, Im not taking to much attention on this...Should I??

(On the other hand, I posted this here cause I found funny the "Treason uncloaked!" part of the message :P)

Since I don't have a copy of the source, this site will do. It originates here:


if (!tp->snd_wnd && !sock_flag(sk, SOCK_DEAD) &&
!((1 << sk->sk_state) & (TCPF_SYN_SENT | TCPF_SYN_RECV))) {
/* Receiver dastardly shrinks window. Our retransmits
* become zero probes, but we should not timeout this
* connection. If the socket is an orphan, time it out,
* we cannot allow such beasts to hang infinitely.

What it means, I have no idea...
