Package: atftpd
Version: 0.7-1
Severity: normal
Hello,
While trying to fix bug #275052 and #271816, I found another well known tftp
server bug : the Sorcerer's Apprentice bug.
You can find a description at http://www.freesoft.org/CIE/RFC/1123/77.htm, and
in RFCs.
In short, the server must never resend the current DATA packet on receipt of a
duplicate ACK.
I was testing atftpd/atftp with a loaded network, a few packets were lost, the
client sent duplicate acks (in multicast mode) and atftpd started to send all
the packets twice...
Cheers,
Ludovic.
