#9 encoding fails under 64bIt system

[Anonymous]

encoding config-files on a x86_64 (AMD64) fails for
some of the given example config-files.
e.g. docsis20.cfg
a little debugging reveals the following:

in routine encode_one_file(...) [docsis.c]

/* walk the tree to find out how much memory we need */
/* leave some room for CM MIC, CMTS MIC, pad */
buflen = tlvtreelen (global_tlvtree_head);

buflen on a 32bit system is 1853

but on the 64bit system i get a buflen of 1762326

the values that were read match on both systems (set
DEBUG for docsis_encode.c and the output was the same),
but - imho -something goes wrong within the creation of
the TLV's.

version: docsis-0.9.5

I have the same probleme. After two days of making setting with dhcpd/tftp/time and reendcode the files, i put my laptop that has an 32bit CPU and OS and it works fine!!!

After that i check the files generated by docsis compiled on 64bit OS and docsis compiled on 32bit and the result was very strange: files has differences. I run the docsis compiled on 32bit on 64bit machine with 64bit OS and it works fine! The same probleme i had on another 64bit machine.

After that i found the Bugs Tracking System and when i want to sumbit the bug .. i found that it was allready submited :)

I hope the probleme will be soon repaired.

The answer was in an old bug report:

after a change in md5.h

from

/* UINT4 defines a four byte word */
typedef unsigned long int UINT4;#

to
/* UINT4 defines a four byte word */
typedef unsigned int UINT4;

you can run the 32 bit version with ia32-libs
http://www.debian-administration.org/articles/531

dont forget to run run ldconfig at the end.

Hy. I found that docsis is not compiling corectly at all on 64 bit sistems. There are a lot of things that should be made portable between 32bit and 64bit. After i change the code for variables like short/int/long int/long long to int16_t/int32_t/int64_t, i found that TLVs got big problems.

I thing the problem comes from docsis_yy.y and docsis_lex.l . Even i made the above changes into those file, after compile the docsis_yy.c/docsis_lex.c there are variables that uses short/int/long int/long long.

Personaly i'm out of ideas :( ..

I'm taking over the abandoned docsis project. I've accepted a patch to fix this in revision 54e1fd206486843ddf508321a0de895a35429bd9 on http://github.com/rlaager/docsis. I hope to cut a 0.9.6 release soon, ideally today. Thanks for the bug report.
