Hi! I wrote a small module to fulfil a privacy policy where logging of the ip address is not allowed. It adds a new directive to LogFormat which generates a MD5 hash of a "salted" ip address. It makes it look like a IPv6 address. Thus statistics tools like AWstats have a chance to work.
Unfortunately writing a module isn't documented well. So some issues are still open. The source code is available on github: http://github.com/franzs/mod_log_iphash How should the module react to a failed initialization of seed_rand() in iphash_create_server_config() (line 90)? Returning NULL in iphash_create_server_config() doesn't seem to help. I'd like to disable the module somehow if the random generator could be initialized properly. No other module checks if the return value of apr_palloc() or apr_pcalloc() is NULL. Does it mean memory allocation via apr_palloc() will never fail and memory size is indefinitely? ;-) If you find other issues in mod_log_iphash please let me know. This is my first module so please be gentle... :-) Best regards Franz
