| | | | | | | | | | | | | | | | | | | | | | | | | | | Confirmed behavior of a Cisco 6509 in production. In the old TFTP server, there was an undocumented behavior where the block counter would rollover to 0 if a file larger than 65535 blocks was transferred. With the default block size of 512 octets per block, this is a file size of approximately 32 megabytes. The new TFTP server code would report an error and stop transferring the file if a file was larger than 65535 blocks. This patch restores the old TFTP server's behavior to the new TFTP server code. If a TFTP client transfers a file larger than 65535 blocks, and does *not* specify the "rollover" option, then automatically rollover the block counter to 0 every time we reach 65535 blocks. This restores interoperability with the FreeBSD 6 TFTP client. Without this change, if a FreeBSD 6 TFTP client tried to retrieve a file larger than 65535 blocks from a FreeBSD 9 TFTP server, the transfer would fail. The same file could be retrieved successfully if the same FreeBSD 6 TFTP client was used against a FreeBSD 6 TFTP server. Notes: svn path=/stable/8/; revision=227083

It is a lot better than what's in the tree now. Edwin tested it at a prior employer, but can't test it today. I've found that it works a lot better with the various uboot versions that I've used in my embedded work. Here's the pkg-descr from the port that describes the changes: It all started when we got some new routers, which told me the following when trying to upload configuration or download images from it: The TFTP server doesn't support the blocksize option. My curiousity was triggered, it took me some reading of RFCs and other documentation to find out what was possible and what could be done. Was plain TFTP very simple in its handshake, TFTP with options was kind of messy because of its backwards capability: The first packet returned could either be an acknowledgement of options, or the first data packet. Going through the source code of src/libexec/tftpd and going through the code of src/usr.bin/tftp showed that there was a lot of duplicate code, and the addition of options would only increase the amount of duplicate code. After all, both the client and the server can act as a sender and receiver. At the end, it ended up with a nearly complete rewrite of the tftp client and server. It has been tested against the following TFTP clients and servers: - Itself (yay!) - The standard FreeBSD tftp client and server - The Fedora Core 6 tftp client and server - Cisco router tftp client - Extreme Networks tftp client It supports the following RFCs: RFC1350 - THE TFTP PROTOCOL (REVISION 2) RFC2347 - TFTP Option Extension RFC2348 - TFTP Blocksize Option RFC2349 - TFTP Timeout Interval and Transfer Size Options RFC3617 - Uniform Resource Identifier (URI) Scheme and Applicability Statement for the Trivial File Transfer Protocol (TFTP) It supports the following unofficial TFTP Options as described at http://www.compuphase.com/tftp.htm: blksize2 - Block size restricted to powers of 2, excluding protocol headers rollover - Block counter roll-over (roll back to zero or to one) From the tftp program point of view the following things are changed: - New commands: "blocksize", "blocksize2", "rollover" and "options" - Development features: "debug" and "packetdrop" If you try this tftp/tftpd implementation, please let me know if it works (or doesn't work) and against which implementaion so I can get a list of confirmed working systems.

| | | | | | | | | | | | | | | | | | | | Reducing "/+./" strings to "/" Reducing "/[^/]+/../" to "/" o Don't send an OACK when the result of the [RW]RQ is an error. These changes allow tftpd to interact with pxelinux.bin from the syslinux package. Whilst the path reducing code doesn't properly handle situations where the path component before the "/../" is a symlink to (say) ".", I would suggest that it does the right thing in terms of the clients perception of what their path string actually represents. This seems better than using realpath() and breaking environments where symlinks point outside of the directory hierarchy that tftpd is configured to allow. Notes: svn path=/head/; revision=130834
