(gethostbyname_r is not supported). + +When a call to one of these functions is intercepted, a SOCKS4A resolve +request is used to retrieve the relevant information, and the results are +cached. + +When the application calls 'connect', the cache is consulted and instead +of making a SOCKS5 request and supplying the IP address, we connect using +the name. This prevents those messages in the tor logs which look like: + + Sep 23 10:12:20.901 [warn] fetch_from_buf_socks(): Your application (using s + ocks5 on port 80) is giving Tor only an IP address. Applications that do DNS + resolves themselves may leak information. Consider using Socks4A (e.g. via + privoxy or socat) instead. + +There are special provisions for handling .onion sites. When a program asks +to resolve a name ending in '.onion', no name lookup is performed. A bogus IP +address is returned. The range of unused IP addresses to hand out is called the +"deadpool". This IP address doesn't mean anything in particular, and could be +considered a cookie associated with the name. When the application eventually +calls 'connect' with this bogus IP, the cache is consulted and the result is a +SOCKS5 request which includes the name of the .onion site. + +The default deadpool range is '127.0.69.0/255.255.255.0'. NOTE: if a resolve +request results in an IP from the deadpool range then the response is rejected, +and it appears to the application that the lookup failed. + +The lookup cache is kept in mmap'd memory and shared across fork() calls. +This is because some programs perform name lookups in a child process and +then invoke 'connect' in the parent as a kind of "poor man's async DNS". + + +Advanced configuration options +------------------------------ + +The following options have been added to the tsocks configuration file: + +tordns_enable + + The default value is 'true'. If you set it to 'false', tsocks should work + just like it did without the tordns patch. + + +tordns_deadpool_range + + The default value is '127.0.69.0/255.255.255.0'. This specifies what range + of IP addresses will be handed to the application as "cookies" for .onion + names. Of course, you should pick a block of addresses which you aren't + going to ever need to actually connect to. + + +tordns_cache_size + + This specifies the number of IP addresses looked up through socks to cache. + The default value is 256. The default value is 256. Each entry consumes 260 + bytes of memory, so the default adds 66,560 bytes of overhead to each + 'torified' process. NOTE: if the number of IP addresses in + tordns_deadpool_range is less than the value specified for tordns_cache_size, + then the cache will be shrunk to fit the deadpool range. This is to prevent + duplicate deadpool addresses from ever appearing in the cache. + + +TODO +---- + +* Think about how local names get resolved. Is it important? For example, + if I 'telnet localhost' which using tordns, what should happen? Should + we search through /etc/hosts ourselves or what? + +* What about the isc library calls like res_init and so on? How widely are + they use? Does this present a more elegant way to implement this stuff? + +* Perhaps intercept res_query etc and try to do something appropriate. + +* It should be possible to make this thread-safe with --enable-threads. + +* validateconf needs to be updated to understand (and show information about) + the tordns configuration options. + +* Perhaps intercept reverse name lookups? + +* In fact, one could modify tsocks further to play nicely with tor.
