Hide Forgot
From Bugzilla Helper: User-Agent: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:0.9.6) Gecko/20011120 Description of problem: The 0.17 distribution of TFTP (currently available on RawHide) once again includes its own copy of the <arpa/tftp.h> header file. The structures defined therein are transmitted over ethernet and therefore the compiler must not add any additional padding to them. This was reported and fixed in RedHat 6.2 but the patch seems to have been lost. Why do you need to supply your own headers anyways? The system header, which is part of glibc-devel, has the correct definitions in them. Building against that header file results in correct operation of the daemon. As distributed the tftp service is totally broken on platforms like ARM where the compiler will insert padding bytes in structures to align things on 32-bit boundaries by default. Version-Release number of selected component (if applicable): tftp-0.17-14 How reproducible: Always Steps to Reproduce: 1. Build/install tftp-0.17 on ARM platform 2. Start the server via inetd/xinetd 3. Try to retrieve a file (for example) tftp > connect localhost > get /boot/vmlinux Actual Results: An error message similar to: The number varies randomly (its garbage data from uninitialized memory) TFTP- Error 16283 - GAL operation Expected Results: The requested file should have been transferred. Additional info: This is easily fixed by removing the arpa/tftp.h header file included with the package. If that is not acceptible, then the struct tftphdr needs to be modified to have __attribute__ ((__packed__)) right before the th_u member, and once again after the closing brace of the same structure definition. I can provide a patch if this is not obvious.
This might well affect current shipping versions of RH (7.x) as well - I haven't checked. It was working correctly in tfp-0.15-1.src.rpm, which dates back to the early RedHat 6.x time if I'm not mistaken.
I just removed the file...
