Only a subset of the src/lib/resolv part of libbind is +included here; basically the parts that are needed to provide the +functionality present in the resolver from BIND 4.9.7 that was +included in the previous release of the GNU C Library, augmented by +the parts needed to provide thread-safety. This means that support +for things as dynamic DNS updates and TSIG keys isn't included. If +you need those facilities, please take a look at the full BIND +distribution. + + +Differences +=========== + +The resolver in the GNU C Library still differs from what's in BIND +8.2.3-T5B: + +* The resolver in glibc strictly adheres to the recommendations in RFC + 1535. BIND 8.2.3-T5B seems to relax those rules a bit (see the code + that's wrapped in `#ifndef RFC1535'). + +* The RES_DEBUG option (`options debug' in /etc/resolv.conf) has been + disabled. + +* The resolver in glibc allows underscores in domain names. + +* The <resolv.h> header in glibc includes <netinet/in.h> and + <arpa/nameser.h> to make it self-contained. + +* The `res_close' function in glibc only tries to close open files + referenced through `_res' if the RES_INIT bit is set in + `_res.options'. This fixes a potential security bug with programs + that bogusly call `res_close' without initializing the resolver + state first. Note that the thread-safe `res_nclose' still doesn't + check the RES_INIT bit. By the way, you're not really supposed to + call `res_close/res_nclose' directly. + + +Source code +=========== + +The following files come from the BIND distribution (currently version +8.2.3-T5B): + +src/include/ + arpa/nameser.h + arpa/nameser_compat.h + resolv.h + +src/lib/resolv/ + herror.c + res_comp.c + res_data.c + res_debug.c + res_debug.h + res_init.c + res_mkquery.c + res_query.c + res_send.c + +src/lib/nameser/ + ns_name.c + ns_netint.c + ns_parse.c + ns_print.c + ns_samedomain.c + ns_ttl.c + +src/lib/inet/ + inet_addr.c + inet_net_ntop.c + inet_net_pton.c + inet_neta.c + inet_ntop.c + inet_pton.c + nsap_addr.c + +src/lib/isc/ + base64.c + +Some of these files have been optimized a bit, and adaptations have +been made to make them fit in with the rest of glibc. The more +non-obvious changes are wrapped in something like `#ifdef _LIBC'. + +res_libc.c is home-brewn, although parts of it are taken from res_data.c. + +res_hconf.c and res_hconf.h were contributed by David Mosberger, and +do not come from BIND. + +The files gethnamaddr.c, mapv4v6addr.h and mapv4v6hostent.h are +leftovers from BIND 4.9.7. |
