Fork of the original (unmaintained?) atftp client and server from https://sourceforge.net/p/atftp/ -- it has several bug reports open for years now, some of them crashes, invalid memory accesses, some users even provided patches. This is an attempt to fix most of the issues since we (still) run atftpd in production. Maybe this code dump will hel…

This is a fork of what seems to be the latest official atftp code base on sourceforce (https://sourceforge.net/p/atftp/). As of now I don't plan on extending atftp but just fix bugs, due to time constraints. The one exception is the rollover patch to support large file transfers, taken from a PR to opsi-atftp (opsi-org/opsi-atftpd#1) Feel free to open issues for any problems you encounter. Since I'm not at all familiar with the code base there's some chance something broke though my patching, although the test.sh from the test directory still reports that all is well. The motivation for this repo was that we suddenly encountered frequent crashes under high load which were easily reproduced and tracked down to a race condition. Researching revealed that there seems to be no active maintainer for atftp, nor did I find any forks that try to address any of the bugs that have been reported on the original sourceforge project page. Regarding the state of atftp we're currently considering moving away from it. Until we've decided on a replacement, this is the version that's running in production. Original unmodified README content follows: Jean-Pierre Lefebvre <helix@step.polymtl.ca> August 20th, 2000 ----------------- atftp stands for Advanced Trivial File Transfer Protocol. It is called "advanced", by contrast to others TFTP servers, for two reasons. Firstly, it is intended to be fully compliant with all related RFCs. This include RFC1350, RFC2090, RFC2347, RFC2348 and RFC2349. To my knowledge, there is no TFTP server currently available in the public domain that fulfills this requirement. Secondly, atftp is intended for serving boot files to large clusters. It is multi-threaded and support multicast (RFC2090 and PXE), allowing faster boot of hundreds of machine simultaneously. I started writing the atftp server after trying to boot Debian from the LAN using pxelinux (distributed with syslinux). Since pxelinux needs support for the "tsize" option defined in RFC2349, I looked for different TFTP servers but found none that fulfilled my needs. With atftp, I have successfully used pxelinux and dhcpd to boot from the LAN. Unfortunately, new development will slow down since I do it on my spare time and atftp now does what I need. However, atftp is actively maintained. Comments, bug reports and patches are welcome. Great thanks to my brother Remi who works on the client and server implementation and the debian packaging.
