Subject: [Qemu-devel] The TFTP server has the Sourcerer's Apprentice bug
Date: Sun, 02 Aug 2009 15:18:21 -0700 [thread overview]
Message-ID: <4A7610AD.4040901@zytor.com> (raw)
Hello,
I was investigating a failure to TFTP boot, and I found that the TFTP
server in Qemu has the Sourcerer's Apprentice bug (see RFC 1123, section
4.2.3.1. Specifically, it is *required* that the sending side:
a) MUST NOT retransmit in response to a duplicated ACK.
b) MUST retransmit based on timeouts.
(a) is trivial to fix, but (b) requires a little more knowledge of the
internals than I'm willing to devote my Sunday afternoon to fixing...
