2004-05-08  Paul  Rombouts  <p.a.rombouts@home.nl>

	* src/rc/Slackware/rc.pdnsd
	I've included a Slackware start-up script contributed by Nikola Kotur.

2004-05-05  Paul Rombouts  <p.a.rombouts@home.nl>

	* doc/pdnsd.8
	I'm very grateful to Mahesh T. Pai for contributing a pdnsd man page,
	which was still missing up till now.

2004-04-30  Paul Rombouts  <p.a.rombouts@home.nl>

	* src/servers.c,src/dns_query.c
	After considering some suggestions made by Juliusz Chroboczek I have made the
	following changes:

	- After receiving a reply from a remote server mark the server up and update the
	timestamp so that pdnsd doesn't bother testing this server for availability for a
	while.
	- After detecting an error with an send/recv call that indicates a server is
	unavailable, mark a server down so that pdnsd doesn't bother testing this server
	for a while.
	- After server timeouts, uptests are never performed by a query/answer thread,
	because this may delay the sending of an answer to the client. Instead the
	timestamp of a server that needs to be tested for availability is set to zero and
	a condition signal is sent to alert the server status thread, which will carry out
	the test. Unresponsive servers with uptest=ping will not be marked down
	immediately any more, but only after the ping test has definitely failed.

	* src/error.c,src/error.h
	I've moved most of the code previously contained in the DEBUG_MSG macro to a new
	function debug_msg().
	The DEBUG_MSG macro now simply expands to "if(debug_p) debug_msg();".
	This should make the executable a little smaller, and be just as fast when
	debugging is off. The DEBUG_MSG macro still expands to nothing if pdnsd is built
	without debugging support.

2004-04-28  Paul Rombouts  <p.a.rombouts@home.nl>

	* src/dns_query.h,src/dns_query.c
	I've tried to simplify the finite state machine used for processing parallel
	queries, by merging the "state" and "nstate" variables used by p_exec_query() and
	p_query_sm() resp. into one "state" variable.
	By introducing an extra field "iolen" to keep track of the number of bytes read
	from or written to a socket, I could also reduce the number of states for TCP
	queries. The new code has the additional advantage that it can handle situations
	that require multiple read() calls to receive a response.

2004-04-14  Paul Rombouts  <p.a.rombouts@home.nl>

	* src/dns_query.c
	I've added an extra check comparing the number if poll/select events actually
	handled to the return value of poll/select. This should reduce the chance that
	pdnsd will get caught in a busy spin due to unknown remaining bugs. An error
	message is logged and an error code is returned when this comparison fails.

2004-04-13  Paul Rombouts  <p.a.rombouts@home.nl>

	* src/dns_query.h,src/dns_query.c
	I got rid of the event field in the query_stat_t struct.
	I think it is redundant, because its value can be quite simply derived from
	the nstate field.

2004-04-12  Paul Rombouts  <p.a.rombouts@home.nl>

	* src/dns_query.c
	I appears there was flaw in the code for handling a "Not Implemented" response
	from a remote server with the RA (recursion available) bit equal to zero. This
	could cause pdnsd to get into a busy spin. I traced the flaw back to Thomas
	Moestl's code, so it must be in all the versions of pdnsd I know of. In previous
	versions of pdnsd the busy spin would eventually time out. Due to some recent
	changes the loop would no longer time out, making the bug more noticeable.
	With thanks to Nicolas George for reporting the bug.
	
	I also discovered a closely related flaw that would cause pdnsd to poll() closed
	file descriptors. It usually works out OK in practice, but it is definitively not
	the correct way to do it.

	Additionally, I discovered some opportunities to save memory, e.g. by replacing
	the nsname buffer in the query_stat_t struct by a pointer to an already existing
	copy of a name.

2004-04-10  Paul Rombouts  <p.a.rombouts@home.nl>

	* src/cache.c
	Nicolas George remarked that he thought it was strange that subdomains of domains
	negated with "neg" sections in the config file were not also negated. I thought that
	he had a point, and I've implemented a change so that negating example.com will
	now also negate www.example.com, xxx.adserver.example.com, etc.

2004-04-09  Paul Rombouts  <p.a.rombouts@home.nl>

	* src/error.c,src/error.h
	I noticed that the code for the log_warn() and log_error() functions was almost
	identical, even to the point that log_warn() called syslog() with LOG_ERR
	priority. I've merged these two functions into one log_message() function.

2004-04-08  Paul Rombouts  <p.a.rombouts@home.nl>

	* src/main.c,src/conf-parser.c
	The -4 and -6 command-line options should now work as advertised.
	This wasn't entirely trivial. The rule is that options on the command line
	override those in the configuration file. The easiest way to implement this is to
	process the command-line options after reading the configuration file. But this
	doesn't work for the -4 and -6 options, because the run_ipv4 flag determines how
	IP addresses in the config file are parsed. I've inserted some extra tests and
	warning messages that will hopefully make this setting nearly foolproof.

	I've added two new command-line options, "-a" and "-i <prefix>".
	With the -a flag pdnsd will try to detect automatically if IPv6 support is
	available on a system, and fall back to IPv4 if not. The -a flag can be used
	instead of -4 or -6.

	In IPv6 mode, pdnsd will now automatically convert IPv4 addresses to IPv6-mapped
	addresses. The -i option can be used to specify a prefix for this mapping. The
	default is ::ffff.0.0.0.0
	There is also a corresponding ipv4_6_prefix= option for the config file.

	In IPv4 mode, if IPv6 support is compiled in, pdnsd will now skip IPv6 addresses
	in the config file (except for the server_ip and ping_ip options) with a warning
	message. This allows you to have mixed sets of IPv4 and IPv6 address in the same
	config file, although in IPv4 mode some server sections may become inactive.

	With thanks to Juliusz Chroboczek for suggesting these changes.

2004-04-07  Paul Rombouts  <p.a.rombouts@home.nl>

	* src/cache.c
	I've changed some of the cache-flag definitions to make debugging a little simpler.
	Unfortunately, this makes the cache files of previous pdnsd versions incompatible
	with the new one. I've introduced a cache version identifier to be added at the
	beginning of each cache file. This enables pdnsd to recognize and discard
	incompatible cache files.

2004-04-05  Paul Rombouts  <p.a.rombouts@home.nl>

	* src/cache.h,src/cache.c
	I've changed the way CACHE_LAT (cache latency, normally 120 secs) is used to
	determine whether a cache entry has timed out. Instead of simply adding it to the
	ttl (time to live), I use CACHE_LAT if the ttl is less then CACHE_LAT, else the
	ttl itself, making CACHE_LAT the minimum ammount of time a cache entry stays in
	the cache.

2004-04-02  Paul Rombouts  <p.a.rombouts@home.nl>

	* src/dns_query.c
	I've introduced a global timeout parameter. This is the minimum period of time
	pdnsd will wait after sending the first query to a remote server before giving
	up without having received a reply.
	The timeout options in the configuration file are now only minimum timeout intervals.
	Setting the global timeout option makes it possible to specify quite short timeout
	intervals in the server sections. This will have the effect that pdnsd will start
	querying additional servers fairly quickly if the first servers are slow to respond
	(but will still continue to listen for responses from the first ones).
	This may allow pdnsd to get an answer more quickly in certain situations.

	* src/dns_query.c
	When receiving a NXDOMAIN (unknown domain) response from a remote name server,
	I think it is still useful to process the authority and additional sections,
	so that pdnsd can possibly add a SOA record to its own response.

2004-04-01  Paul Rombouts  <p.a.rombouts@home.nl>

	* src/dns_query.c
	In p_recursive_query(), I've slightly changed the way pdnsd does parallel
	queries. Active queries or not canceled until we have received a useful response
	from a remote name server, or all the queries have failed or timed out.
	Thus the par_queries parameter is no longer the maximum number of parallel
	queries, but rather the increment with which the number of parallel queries is
	increased when the previous set has timed out.
	In the worst case all the servers in the list of available servers will be queried
	simultaneously. We may be wasting more system resources this way, but the advantage
	is that we have a greater chance of catching a reply.
	After all, if we wait longer anyway, why not for more servers.

2004-03-31  Paul Rombouts  <p.a.rombouts@home.nl>

	* src/dns_answer.c
	I've noticed that in compose_answer() that while adding the name in the query
	section it was not passed through compress_name(). While it is true that the
	first name occurrence cannot be compressed, it is still sensible to process the
	query name with compress_name() so that the offset can be stored and provide
	additional opportunities for future compressions.
	I've tested this with dig and the responses of pdnsd are now usually a little
	smaller	in size or can hold more information within the 512 byte limit.

2004-03-30  Paul Rombouts  <p.a.rombouts@home.nl>

	* src/cache.c
	I've noticed that pdnsd stored rr records (of the same type) in reverse order
	in the cache.
	Although I don't see anything inherently wrong with that, I think it's neater to
	store them in the order they are processed.

2004-03-29  Paul Rombouts  <p.a.rombouts@home.nl>

	* src/cache.c
	I've rearranged the order of the arguments of some of the functions in cache.c
	to obtain a more consistent calling interface.

	* src/dns_answer.c
	I've noticed that pdnsd would only add NS records to an authority section if it could
	find such records matching the queried name (or the last CNAME in the answer) exactly.
	However, I understand that a server should try to give NS records as close as possible
	to the target name in the naming hierarchy.
	I also understand that if a domain name is reported as nonexisting, or no record of
	the requested type exists, it is customary to provide a SOA record, searching up the
	name hierarchy if necessary.
	I've tried to implement this in compose_answer(), although with some limitations.
	I only look in the cache, I don't search more then three levels up, and stop before
	the top level.

2004-03-28  Paul Rombouts  <p.a.rombouts@home.nl>

	* src/cache.c,src/dns_answer.c
	There were some issues with add_cache_rr_add().

	First of all, the way it was used in rr_to_cache() (or rather not used) meant
	that if an "off topic" record was added for a name that lacked an entry in the
	cache, the rr set would be created with an incorrect serial number (namely zero).
	I've rewritten add_cache_rr_add so that it can create new cache entries if necessary.
	This simplifies the code in rr_to_cache() and ensures correct serial numbers.

	Secondly, in add_cache_rr_add() the ttl was compared with that of an existing rrset
	without adjusting for the min_ttl and max_ttl options. This could lead to all the
	previous records being deleted, retaining only the last one.

2004-03-27  Paul Rombouts  <p.a.rombouts@home.nl>

	* src/dns_answer.c
	In compose_answer(), if the rd (recursion desired) bit is set in the query
	and the response contains a CNAME record (while a different type of record was
	requested), always do a recursive query on the CNAME, even if we have already
	added a record of the requested type to the response.
	Failing to honor the rd bit will cause some resolver libraries to complain,
	even if the answer contains a record of the requested type.

	I've slightly changed the calling interfaces of add_to_response() and add_rrset()
	to make them more consistent and efficient.

	In add_rrset() I've fixed a memory leak on one of the error paths.

	In add_additional_rr(), the return value of add_rr() was not checked.
	If add_rr() fails, it will free *ans, and functions higher up the calling
	chain could be referencing freed memory.

	I've fixed a potential referencing of freed memory or double freeing in add_additional_a().
	If a call of add_additional_rr() fails, it will free *ans.
	Previously, add_additional_rr() could be called a second time, in which case
	the second call would be referencing freed memory or freeing it a second time..

2004-03-23  Paul Rombouts  <p.a.rombouts@home.nl>

	* configure.in, src/Makefile.in,src/pdnsd-ctl/Makefile.in,src/test/Makefile.in
	Frdric L. W. Meunier has reported that configure --srcdir option (for building
	in directory separate from the source directory) was broken.
	Should be fixed now.

2004-03-20  Paul Rombouts  <p.a.rombouts@home.nl>

	* src/dns_answer.c,src/dns_query.c,src/helpers.c,src/icmp.c,src/main.c,src/netdev.c,src/ipvers.h,src/test/if_up.c,src/test/is_local_addr.c,src/test/tping.c,src/test/random.c,src/conf-parser.c
	I've eliminated the global variable run_ipv6 from the code.
	Enabling both the IPv4 and IPv6 protocols at the same time is not supported
	in pdnsd, so the value of run_ipv6 (if it is defined) is simply !run_ipv4.

	* src/dns.c,src/test/is_local_addr.c,src/test/tping.c
	It appears the option to compile pdnsd without IPv4 support (i.e. only IPv6
	support) was broken. Should be fixed now.
	
2004-03-19  Paul Rombouts  <p.a.rombouts@home.nl>

	* src/cache.c
	I've discovered an incorrect use of cache locks in lookup_cache().
	We only read locks in place, it is possible for purge_cent() to delete a cache
	entry while another thread is trying to read it at the same time, which could
	lead to	trouble. I've rewritten purge_cent() so that it can be used to test
	whether something needs to be purged without actually deleting anything.
	If something needs to be deleted, purge_cent() will be called again with
	the proper read/write locks in place, excluding access to the cache for all
	other threads.

2004-03-18  Paul Rombouts  <p.a.rombouts@home.nl>

	* src/cache.c
	I've added a new function sort_rrl() for sorting the rr_l list using a merge-sort
	algorithm. Usually the insertion sort used by insert_rrl() is good enough, because
	new entries belong near the end most of the time. Reading entries from disk forms
	an exception, though, because the rrsets in the file are completely out of order
	w.r.t. timestamps, leading to quadratic time complexity of the insertion sort method.
	In that case it should be faster to simply append items at the end of the rr_l list
	and sort using a more efficient algorithm afterwords.
	pdnsd now seems to start up noticeably faster when reading large cache files.
	I've also considered using a more sophisticated data structure than a doubly linked
	list, but this will add considerable complexity to the code and use more memory.

2004-03-13  Paul Rombouts <p.a.rombouts@home.nl>

	* src/dns_answer.c
	Changed a declaration in udp_answer_thread() so that the buffer used for passing 
	control messages on to sendmsg() is exactly the right size, instead of an arbitrary
	512 bytes.
	Also initialized the msg_flags of the struct msghdr passed on to sendmsg() to zero,
	to keep Valgrind from complaining about uninitialized bytes.

2004-03-12  Paul Rombouts <p.a.rombouts@home.nl>

	* src/icmp.c
	Fixed an incorrect call to select() in ping4(). A file descriptor set for detecting
	exceptions was initialized but not passed on to select(). This would lead subsequent
	code always to behave as if an IO exception had occurred.
	Valgrind seems to indicate that when a poll() call times out and returns 0,
	the revents field of the struct pollfd is not necessarily set.
	I've changed the code to check that the return value is > 0 before examining the
	revents field.

2004-02-06  Paul Rombouts <p.a.rombouts@home.nl>

	* src/conf-parser.c,src/conf-parser.h,src/conf-keywords.h
	I've rewritten the parser for the configuration file in C from scratch.
	(f)lex and yacc/bison are no longer needed to build pdnsd.

2004-01-16  Paul Rombouts <p.a.rombouts@home.nl>

	* src/main.c
	Load the cache from disk without locking cache access because pdnsd
	is still single-threaded at that point.

2004-01-15  Paul Rombouts <p.a.rombouts@home.nl>

	* src/cache.c,src/hash.c
	Moved the responsibility for freeing the cache entries referred by
	the hash buckets from destroy_cache() to free_dns_hash() (which is called
	by destroy_cache()). Previously, the cache and hash tables were already
	completely destroyed by the time free_dns_hash() was called, and there was
	nothing left for free_dns_hash() to free.

2004-01-14  Paul Rombouts <p.a.rombouts@home.nl>

	* src/hash.c,src/make_hashconvtable.c
	The hash conversion table is now generated at build time instead
	of at run time when pdnsd is started up.

2004-01-13  Paul Rombouts <p.a.rombouts@home.nl>

	* src/dns.c
	In add_host() fixed incorrect generation of IPV6 type of name for PTR record
	due to use of && instead of & as masking operator.

2004-01-13  Paul Rombouts <p.a.rombouts@home.nl>

	* src/icmp.c, src/dns_answer.c
	Use unsigned long instead of int error counters to reduce the danger
	of wraparound.

2004-01-06  Paul Rombouts <p.a.rombouts@home.nl>

	* src/main.c,src/thread.c,src/thread.h,src/server.c,src/status.c,src/dns_answer.c
	Initialize a global thread attribute object in main.c and use it to create all the detached
	threads, instead of initializing a separate attribute object for each new thread.

2004-01-06  Paul Rombouts <p.a.rombouts@home.nl>

	* src/dns_answer.c
	Check the return value of pthread_create() in udp_server_thread()
	and tcp_server_thread() to ensure that a new answer thread has actually
	been created and free resources if not.

2004-01-04  Paul Rombouts <p.a.rombouts@home.nl>

	* src/helpers.c,src/cache.c,src/conff.c,src/status.c
	Stop writing to control socket after an error has been detected.

2004-01-03  Paul Rombouts <p.a.rombouts@home.nl>

	* src/pdnsd-ctl/pdnsd-ctl.c
	Tried to make the error messages of pdnsd-ctl more helpful.
	The complete usage description is now only printed if the 'help' command
	is used. For problems with other commands a much shorter message is generated
	specific for that command.

2004-01-02  Paul Rombouts <p.a.rombouts@home.nl>

	* src/helpers.h
	Changed the definition of rhnlen(). For valid data this will make no difference,
	but it may change the behaviour of pdnsd in certain error situations.

2004-01-02  Paul Rombouts <p.a.rombouts@home.nl>

	* src/dns.c
	Optimized compress_name() some more.

2004-01-02  Paul Rombouts <p.a.rombouts@home.nl>

	* src/dns_answer.c
	Additional code cleanup in compose_answer().

2004-01-01  Paul Rombouts <p.a.rombouts@home.nl>

	* doc/pdnsd-ctl.8
	Updated the pdnsd-ctl man page.

2003-12-31  Paul Rombouts <p.a.rombouts@home.nl>

	* src/pdnsd-ctl/pdnsd-ctl.c
	Cleaned up some code.

2003-12-31  Paul Rombouts <p.a.rombouts@home.nl>

	* src/status.c,src/conff.h,src/conff.c
	Some further code cleanup in status.c.
	Labels for server sections are no longer limited to 32 chars,
	but can have arbitrary length. The string that is used to specify
	new DNS-addresses with the "pdnsd-ctl server" command can now also
	have arbitrary length.

2003-12-30  Paul Rombouts <p.a.rombouts@home.nl>

	* doc/html/doc.html
	Added information about CNAME and MX resource records, that were
	previously undocumented.

2003-12-26  Paul Rombouts <p.a.rombouts@home.nl>

	* src/dns_query.c
	Removed the function p_dns_resolve_from(). This function was essentially
	a call to p_recursive_query() with a dummy nocache argument.
	p_recursive_query() can now be called with nocache=NULL instead.

2003-12-26  Paul Rombouts <p.a.rombouts@home.nl>

	* src/dns_query.c
	Using a variable length array instead of an malloced buffer to hold the struct pollfd array
	in p_recursive_query(). This has the potential for causing portability problems, but I
	think that's unlikely because almost all the major C compilers I work with support variable
	length arrays nowadays.

2003-10-18  Paul Rombouts <p.a.rombouts@home.nl>

	* src/helpers.h,src/helpers.c
	Fixed a mistake that caused a compile error when using the --with-random-device
	configuration option.
	Thanks to Daniel Black for reporting this bug.

2003-10-02  Paul Rombouts <p.a.rombouts@home.nl>

	* conf-lex.l.in,src/conf-parse.y,src/conff.h,src/conff.c,src/dns_query.c
	Made the "delegation_only" feature configurable.

2003-09-25  Paul Rombouts <p.a.rombouts@home.nl>

	* src/helpers.c,src/helpers.h
	Added alternative implementations of strdup, strndup, stpcpy, getline and asprintf
	in an effort to make the code more portable.

2003-09-22  Paul Rombouts <p.a.rombouts@home.nl>

	* src/helpers.c,src/conf-parse.y
	Made some changes to the parser of the configuration file so that domain names
	missing a dot at the end will be tolerated.

2003-09-21  Paul Rombouts <p.a.rombouts@home.nl>

	* src/dns_query.c
	Implemented a first version of the "delegation-only" feature.
	It has been "hard-coded" to work for "com" and "net" zones,
	and is not yet configurable.

2003-09-21  Paul Rombouts <p.a.rombouts@home.nl>

	* src/dns.c
	Rewrote domain_match(). Also changed the way it is used.
	I believe it has a cleaner semantics now.

2003-09-21  Paul Rombouts <p.a.rombouts@home.nl>

	* src/dns_query.c
	Changed the order of the arguments of p_exec_query() and p_recursive_query()
	to make it more consistent with the other functions.

2003-09-18  Paul Rombouts <p.a.rombouts@home.nl>

	* src/dns_answer.c
	Reordered the code in process_query() so that a buffer for an error response is
	allocated only when it is actually needed.

2003-09-17  Paul Rombouts <p.a.rombouts@home.nl>

	* src/cache.c
	Added parentheses to correct mistaken operator precedence assumption in cache.c.
	!cent->flags&DF_NEGATIVE is parsed as (!(cent->flags))&DF_NEGATIVE but I think 
	what Thomas Moestl must have intended was !((cent->flags)&DF_NEGATIVE).

2003-09-12  Paul Rombouts <p.a.rombouts@home.nl>

	* src/dns_query.c
	Fixed a mistake which caused the effect of the proxy_only option to be reversed.
	Thanks to Andrew M. Bishop <amb@gedanken.demon.co.uk> for reporting this bug.

2003-09-11  Paul Rombouts <p.a.rombouts@home.nl>

	* src/helpers.c
	Rewrote str2rhn() and rhn2str().

2003-09-10  Paul Rombouts <p.a.rombouts@home.nl>

	* src/dns.c
	Rewrote read_hosts(), the function that reads /etc/hosts-style input.
	I believe the parsing algorithm is more robust now.

2003-09-09  Paul Rombouts <p.a.rombouts@home.nl>

	* src/status.c,src/pdnsd-ctl/pdnsd-ctl.c
	Fixed a bug (my fault) that caused improper passing on of flags for the
	pdnsd-ctl source command.
	Also reordered some of the code, so that data is validated after all of it
	has been read from the control socket. This should prevent a "broken pipe"
	error message if data validation fails.
	Also fixed the reporting of success or failure of the pdnsd-ctl "neg" command.

2003-09-08  Paul Rombouts <p.a.rombouts@home.nl>

	* src/list.c
	Rewrote da_grow1() and da_resize() so that they automatically allocate an array
	if given a NULL argument. This makes the use of da_create() redundant in most cases.

2003-09-08  Paul Rombouts <p.a.rombouts@home.nl>

	* src/conf-parse.y,src/servers.c
	At the suggestion of Greg Norris, I changed the code to allow server sections in the
	configuration file that don't specify any IP addresses. Such a section will remain
	inactive until one or more IP addresses are assigned with the control utility pdnsd-ctl.

2003-09-04  Paul Rombouts <p.a.rombouts@home.nl>

	* src/dns_answer.c,src/dns_query.c
	Oops: in my zeal to declare variables in the smallest possible scope, I ended up
	using a pointer to a struct that was out of scope. My understanding of compilers tells me
	it should work out OK in practice, but it is definitely a no-no.
	Used a union declared in a larger scope instead (which is ugly in another way,
	but equally efficient).
	Also removed a section of redundant code in udp_server_thread().

2003-09-01  Paul Rombouts <p.a.rombouts@home.nl>

	* src/dns_query.c
	Corrected the iteration range of a for loop in p_dns_cached_resolve(), which would
	otherwise cause an array to be indexed out of bounds in the function set_flags_ttl().

2003-08-31  Paul Rombouts <p.a.rombouts@home.nl>

	* src/dns_answer.c
	Added cleanup handlers for freeing the resources passed on to udp_answer_thread() and
	tcp_answer_thread(). This should ensure the resources are freed even if the threads get
	canceled.

2003-08-30  Paul Rombouts <p.a.rombouts@home.nl>

	* src/cache.c
	Revised large portions of code in src/cache.c, used for adding and deleting entries in
	the cache. In particular, I rewrote purge_cache(), which I believe was incorrect.
	I wouldn't be surprised if this was the cause of the crashed (defunct) threads that some
	people were reporting.
	Also fixed some memory leaks.

2003-08-28  Paul Rombouts <p.a.rombouts@home.nl>

	* src/cache.c
	Eliminated the overhead of allocation debugging in the case that ALLOC_DEBUG is not defined.

2003-08-24  Paul Rombouts <p.a.rombouts@home.nl>

	* src/conf-parse.y
	No longer allow certain settings of the query_method option in the configuration file
	if pdnsd is not compiled with the necessary support.
	Thanks to Nikolaus Rath <Nikolaus@rath.org> for reporting the bug.

2003-08-23  Paul Rombouts <p.a.rombouts@home.nl>

	* src/netdev.c
	Fixed a bug in is_local_addr() where the result of fgetc(f) is restricted to type char
	before being compared to EOF, which can result in the comparison always being false.
	Thanks to Gerhard Tonn <GerhardTonn@gammatau.de> for reporting the bug.

2003-07-28  Paul Rombouts <p.a.rombouts@home.nl>

	* doc/html/index.html,doc/html/doc.html,doc/html/dl.html,doc/pdnsd-ctl.8,contrib/README
	Revised the documentation.

2003-07-21  Paul Rombouts <p.a.rombouts@home.nl>

	* src/main.c,src/status.c,src/icmp.c
	Setting stat_pipe=0 after opening or binding the control socket fails.
	This should prevent further use of the control socket if a problem with
	it has been detected previously.
	Also properly initialized the global variable int ping_isocket in src/icmp.c

2003-07-13  Paul Rombouts <p.a.rombouts@home.nl>

	* src/main.c
	Polished the code in main().

2003-07-04  Paul Rombouts <p.a.rombouts@home.nl>

	* src/helpers.c,src/dns_answer.c,src/dns_query.c
	Eliminated the use of inet_ntoa() in favor of the more modern inet_ntop().
	inet_ntop() makes more sense in threaded code and is also recommended in
	the glibc info pages.
	

2003-07-03  Paul Rombouts <p.a.rombouts@home.nl>

	* src/dns_query.c
	Fixed an allocation size error (not mine) in p_exec_query().
	The erroneous size is almost always larger than necessary, so in practice this bug
	just wastes memory. But there is also a possibility that the allocated buffer is too
	small, which would mean trouble.
	Also fixed two memory leaks on some of the error paths in p_exec_query().

2003-06-28  Paul Rombouts <p.a.rombouts@home.nl>

	* acconfig.h,configure.in,src/thread.h
	Extended the configuration option --with-thread-lib.
	Configuring with --with-thread-lib=linuxthreads2 will cause the alternative
	definition of THREAD_SIGINIT suggested by Thomas Moestl to be used.

2003-06-27  Paul Rombouts <p.a.rombouts@home.nl>

	* src/consts.h,src/consts.c,src/conff.c,src/conf-parse.y,src/dns_answer.c
	Added two new configuration options for policies of inclusion/exclusion lists.
	The new policies options are "simple_only" and "fqdn_only".
	This allows me to control to which name servers pdnsd will direct queries for
	simple host names.
	I also polished the code a bit in report_conf_stat(), used for reporting the current configuration.

2003-06-20  Paul Rombouts <p.a.rombouts@home.nl>

	* acconfig.h,configure.in,src/thread.h,src/thread.c
	Added a configuration option --with-thread-lib=nptl.
	This causes the macro THREAD_SIGINIT to be defined as empty in src/thread.h,
	and thread_sig() in src/thread.c is never used.

2003-06-11  Paul Rombouts <p.a.rombouts@home.nl>

	* src/thread.h
	Undid the change to the definition of THREAD_SIGINIT suggested to me by
	Thomas Moestl, after receiving a report of a problem with this change
	from someone running SuSE 7.0.

2003-06-06  Paul Rombouts <p.a.rombouts@home.nl>

	* src/dns_query.c:
	Discovered that I failed to preserve the semantics of Thomas Moestl's code
	when I rewrote a section of code in use_server(). Fixed.

2003-05-19  Paul Rombouts <p.a.rombouts@home.nl>

	* src/cache.c,src/conf-lex.l.in,src/conf-parse.y,src/conff.h,src/dns_answer.c,src/dns_query.c,src/servers.c:
	Merged fixes contained in patch file sent to me by Thomas Moestl with my own version.
	Changing the version to 1.1.8b1 as suggested by the patch file.

2003-02-26  Paul Rombouts <p.a.rombouts@home.nl>

	* pdnsd-1.1.7a-par.diff:
	Made one big patch file from all the changes I made up till now.
	Wrote a description of the changes in a file README.par
	Posted patch file on the web so others can use it.

2003-02-24  Paul Rombouts <p.a.rombouts@home.nl>

	* src/cache.c
	Changed the code that writes the cache to disk.
	Data is now written strictly sequentially, eliminating the need for fseek().
	This seems to have successfully solved the problem I had with corrupt cache files.

2002-05-27  Paul Rombouts <p.a.rombouts@home.nl>

	* ChangeLog:
	Started experimenting with the source code.
	Made many changes between 2002-05-27 and 2002-07-13.
	Too lazy to maintain the ChangeLog.

2002-01-06  Thomas Moestl  <tmoestl@gmx.net>

	* version: Call it 1.1.7.

2002-01-04  Thomas Moestl  <tmoestl@gmx.net>

	* src/dns_answer.c, src/dns_query.c:
	Comment and debug message fixes, more assertions.

2002-01-03  Thomas Moestl  <tmoestl@gmx.net>

	* src/dns.c, src/dns_answer.c, src/dns_query.c:
	More harmless fixes, correct some comments and debug messages, add more
	assertions.

	* NEWS, version: 1.1.7p2, correct NEWS entry.

	* src/helpers.c:
	Make sure the calling thread of pdnsd_exit() terminates immediately.

2002-01-02  Thomas Moestl  <tmoestl@gmx.net>

	* src/dns_answer.c, src/helpers.c, src/icmp.c:
	Fix a few more harmless bugs, more paranoia.

	* src/status.c: Fix yet more, probably harmless, problems.

2002-01-01  Thomas Moestl  <tmoestl@gmx.net>

	* src/dns.h, src/dns_answer.c, src/dns_query.c:
	Fix a few more possible buffer size problems, and add a bunch of
	assertions as last lines of defence.

2001-12-30  Thomas Moestl  <tmoestl@gmx.net>

	* src/dns.c: Build fix (include error.h).

	* NEWS, version: Call it 1.1.7p1, and add a NEWS entry.

	* TODO: Reduce TODO to what actually is still needed.

	* src/dns.c, src/error.h, src/helpers.c:
	Add a bunch of robustness PDNSD_ASSERT()'s.

	* src/dns_query.c:
	Fix a bug which may possibly be remotely exploitable to gain access as
	the user pdnsd runs as.
	This was caused by a dumb single-character mistake :(

	* doc/Makefile.am, configure.in:
	Avoid confusing automake 1.5 by not putting a comment into a make rule.
	Fix CONFDIR passing.

	Submitted by:	GoTaR <gotar@poczta.onet.pl>

	* src/pdnsd-ctl/pdnsd-ctl.c:
	Avoid crashing when the buffer contents received using the status command
	are not terminated.

2001-10-14  Thomas Moestl  <tmoestl@gmx.net>

	* src/rc/SuSE/pdnsd.in, THANKS:
	Fix the stop case for the SuSE rc script: killproc requires the full
	path of the binary as argument (reported by Bernhard Pelz).

2001-09-23  Thomas Moestl  <tmoestl@gmx.net>

	* configure.in:
	Revamp the OS autodetect test. OpenBSD and (hopefully) NetBSD are no longer
	unsupported.

	* src/helpers.c, THANKS:
	Do not try to use arc4random when compiling for NetBSD (submitted by
	Thomas Stromberg).

2001-09-10  Thomas Moestl  <tmoestl@gmx.net>

	* COPYING.BSD: s/REGENTS/AUTHOR/ in one place.

	* src/cache.c:
	It is possible no record of the requested type is present after calling
	cr_add_cent_rr_int() (when the record was marked as being local), so
	check before dereferencing the pointer to the respective rrset.
	Leave the record unmodified when cr_check_add() returns 0.x

2001-07-26  Thomas Moestl  <tmoestl@gmx.net>

	* src/rc/RedHat/pdnsd.in:
	Add a workaround for @sysconfdir@ substitutions containing ${prefix}.
	Spotted by Robert Linden.

2001-07-04  Thomas Moestl  <tmoestl@gmx.net>

	* src/rc/RedHat/pdnsd.in:
	Add a condrestart handler to the Red Hat rc script, and do some general
	cleanup. Contributed by Christian Engstler.

2001-07-02  Thomas Moestl  <tmoestl@gmx.net>

	* src/error.h:
	Attempt to detect a gcc that cannot yet handle ANSI variadic macros,
	and work around this by using the old GCC-style variant.

	* src/conff.c:
	Remove a + at the start of a line that got in when merging a diff by
	hand.

	* src/servers.c: waitpid() returns a pid_t.

	* src/dns.c:
	It's sizeof, not sizof. This should unbreak the IPv6 build. Also silence
	some warnings with appropriate casts.

	* NEWS, version: Call it 1.1.6, and add a NEWS entry.

2001-07-01  Thomas Moestl  <tmoestl@gmx.net>

	* src/conf-lex.l.in, src/conf-parse.y, src/conff.c, src/conff.h, src/dns_query.c, THANKS, version, AUTHORS:
	Added a modified version of Andreas Steinmetz's code for
	query_port_start and query_port_range, and added him to AUTHORS and
	THANKS.

2001-06-23  Thomas Moestl  <tmoestl@gmx.net>

	* src/cache.c:
	Fix a bogon: deleted would not be reset correctly in the first
	purge_cache loop, which could cause pdnsd to loop forever when a
	negative record was after a deleted rr.

2001-06-21  Thomas Moestl  <tmoestl@gmx.net>

	* src/list.h:
	Add (currently unused) list macros that are going to be used in future
	code.

	* src/cache.c:
	Fix a bogon in the rw lock code: we need to wake up a writer if there
	are no readers. The old code was a leftover from a time when
	SUSP_THRESH was just r_pend * x.
	Fix a typo.

2001-06-13  Thomas Moestl  <tmoestl@gmx.net>

	* AUTHORS: Add mention of FreeBSD code to AUTHORS.

	* src/netdev.c:
	Add SIZEOF_ADDR_IFREQ (taken from FreeBSD: _SIZEOF_ADDR_IFREQ, net/if.h
	rev. 1.58.2.1) and add an appropriate copyright notice.
	The reason for this is that other BSDs don't have it, and we are not
	supposed to use underscored macros in portable software.

2001-06-12  Thomas Moestl  <tmoestl@gmx.net>

	* src/icmp.c: Fix double #inclusion of <netinet/ip.h>.
	Noticed by Sebastian Stark.

2001-06-08  Thomas Moestl  <tmoestl@gmx.net>

	* src/dns_query.c, THANKS:
	Allow underscores in the query names reported back, as the comment next
	to the decompress_name call already indicated (but the call gave NULL
	as the uscore parameter, which disables underscores normally).
	Add Michael Strder, who spotted this, to THANKS.

2001-06-06  Thomas Moestl  <tmoestl@gmx.net>

	* src/servers.c, THANKS:
	Fix a bug discovered by Stefan Erhardt (and add him to THANKS): the
	return value of waitpid was misinterpreted.

2001-06-04  Thomas Moestl  <tmoestl@gmx.net>

	* Makefile.am, file-list.base.in, version:
	Bump version to 1.1.6p1; wire up COPYING.BSD so that it gets included
	in RPM's and tarballs.

	* COPYING.BSD:
	Add the BSD-Style copyright notice so that it can be included in binary
	distributions.

2001-06-03  Thomas Moestl  <tmoestl@gmx.net>

	* src/dns.c, src/dns_answer.c, src/dns_query.c, src/helpers.c, src/status.c, NEWS, version:
	Bump version to 1.1.5, and add a NEWS entry for this release.

	Miscellaneous cleanups, mainly in the status.c code; fix a bug that
	could cause heap corruption (rhncpy always clobbered the whole buffer,
	but only the needed space was reserved in add_rr). This should solve
	the crashes some people were seeing (this bug is not an exploitable
	security hole as far as I know; the respective buffer is on the heap,
	as mentioned).

	* src/error.c:
	Paranoia: do not use the argument to crash_msg as a format string
	(crash_msg  is only used with constant strings, though).

2001-06-02  Thomas Moestl  <tmoestl@gmx.net>

	* src/dns.c, src/dns.h, src/dns_answer.c, src/dns_query.c, src/error.h, src/hash.c, src/helpers.c:
	Correct underscore handling for SRV records, and a few comment fixes.

	* src/cache.c, src/conff.c, src/dns_query.c, src/error.h, src/helpers.h, src/status.c:
	Numerous non-critical argument fixes for printf-like functions.

	* src/dns.c: Remove superfluous \n's.

	* src/conf-parse.y, src/dns_answer.c, src/status.c:
	Correct some DEBUG_MSG nits, and fix two format string bugs. One of
	them could allow users that are allowed to use pdnsd-ctl with the
	server (when the status socket is enabled) to gain the privileges of
	the user that runs (the run_as user or the user that started pdnsd on
	Linux when strict_setuid is set to off) pdnsd. The status socket is
	disabled by default, and if it is enabled, it's default permissions
	are quite restrictive, so this isn't a problem for most.

2001-05-30  Thomas Moestl  <tmoestl@gmx.net>

	* src/status.c:
	Make the status permissions actually work (missed last time).

	* src/dns_answer.c, src/main.c, src/status.c, src/status.h:
	Move the status socket initialization to a place where it gets executed
	before any threads are started; this way, we can use umask to set the
	permissions, and avoid a (in this case harmless, but anyway) race
	condition.
	While being there, remove obsoleted comments and places referring to
	the now-socket as fifo.

2001-05-29  Thomas Moestl  <tmoestl@gmx.net>

	* src/cache.c:
	Replace a misuse of CF_LOCAL with DF_LOCAL. This had no effect, because
	the values are the same.

2001-05-22  Thomas Moestl  <tmoestl@gmx.net>

	* src/hash.c, src/helpers.c, THANKS, acconfig.h, configure.in:
	Add an option for allowing underscores (_) in domain names. This
	violates the RFC's if enabled (which it isn't by default).
	Thanks to Eelco Vriezekolk for an initial patch.

	While being there, clean up configure.in and acconfig.c a bit.

	* src/helpers.c, src/status.c:
	Add a few comments about security implications.

	* src/cache.c, src/dns_answer.c, src/dns_query.c, src/helpers.c:
	Change some occurences of strcpy to strncpy. Again, no risk here, the
	buffer lentgh was carefully chosen, and while the data was partially of
	remote origin, it was carefully validated before entering the cache (and
	thus having a chance of being used by us).
	3 occurences remain: 2 in cache.c, where we allocate a sufficient amount
	of memory before (mimicking the non-portable strdup) and one where
	we copy a constant and which is obviously correct.

	* src/dns.c:
	Change two occurences of strcat to strncat. Again, no risk here, the
	buffer lentgh was carefully chosen, the data was validated and supplied
	by the starting user.

	* src/dns.c:
	Change a sprintf to a snprintf and enlarge a buffer a bit. This is pure
	paranoia (alrhough makes code review easier for others), because a.) the
	lengths were carefully chosen so that no overrun could occur and
	b.) this was locally supplied data.

2001-05-21  Thomas Moestl  <tmoestl@gmx.net>

	* src/rc/RedHat/Makefile.am:
	Add a missing semicolon in  the RedHat rc Makefile.am (discovered by
	Christian Engstler).

2001-05-19  Thomas Moestl  <tmoestl@gmx.net>

	* HACKING: Remove the mostly outdated HACKING file.

	* src/debug.c:
	Catch a corner case in the allocation debug helpers: realloc() with a
	size of 0 is effectively a free operation. To my knowledge, this is
	not done in the pdnsd sources, however.

	* src/test/test.sh:
	Use the correct error function, forgotten in last commit.

	* src/test/clnt-test.sh, src/test/srv-test.sh, src/test/test.sh:
	Misc small improvements in the regression test scripts, mostly
	adding configuration variables and common error handlers.
	Comment a little on the tests that are done in clnt-test.sh

	* src/rr_types.c: Fix a typo in a comment.

	* src/cache.c, src/debug.c, src/dns_answer.c, src/dns_query.c, src/error.h, src/hash.c, src/list.c, src/main.c, src/status.c, src/thread.c, src/thread.h:
	New ANSI variadic debug macros (finally), which print a timestamp and
	a thread ID now for easier debugging with many parallel queries.
	It should be considered to make those inline functions instead. However,
	we have the advantage that we use printf in place here and benefit
	from parameter checking without specifying obscure function attributes.

	* src/rc/SuSE/.cvsignore, src/test/.cvsignore, src/rc/.cvsignore, src/rc/Debian/.cvsignore, src/rc/RedHat/.cvsignore, contrib/.cvsignore, doc/.cvsignore, src/.cvsignore, src/pdnsd-ctl/.cvsignore, .cvsignore:
	Brush up the rotten (pre-autoconf!) .cvsignore files and add some where
	necessary.

2001-05-17  Thomas Moestl  <tmoestl@gmx.net>

	* src/rc/RedHat/Makefile.am, src/rc/RedHat/pdnsd.in, configure.in, pdnsd.spec.in:
	Red Hat rc script and RPM improvements by Christian Engstler.

2001-05-12  Thomas Moestl  <tmoestl@gmx.net>

	* src/pdnsd-ctl/pdnsd-ctl.c:
	Fix a place missed when converting rr_info.

	* version: It's 1.1.4, finally.

	* src/rr_types.c, version:
	Change some class values in the rr type structure to better values.
	Bump beta version.

2001-05-10  Thomas Moestl  <tmoestl@gmx.net>

	* src/cache.c, src/dns_answer.c, src/dns_query.c:
	Fix a signedness bug that could cause erraneous 0 ttls to be returned.
	Add some debug messages, and do some minor fixups.

2001-05-09  Thomas Moestl  <tmoestl@gmx.net>

	* src/cache.c, src/rr_types.c:
	Fix some bugs in the new conflict resolution code and make it more
	complete.

	* src/cache.c, version:
	Add conflict resolution code. This needs a bit more checking, and
	the tables might still need to be tweaked.
	Bump version.

	* src/pdnsd-ctl/pdnsd-ctl.c, src/Makefile.am, src/cache.c, src/cache.h, src/conf-lex.l.in, src/conf-parse.y, src/conff.c, src/conff.h, src/consts.c, src/consts.h, src/debug.c, src/dns.c, src/dns_answer.c, src/dns_answer.h, src/dns_query.c, src/dns_query.h, src/error.c, src/error.h, src/hash.c, src/hash.h, src/helpers.c, src/helpers.h, src/icmp.c, src/icmp.h, src/list.c, src/main.c, src/netdev.c, src/netdev.h, src/rr_types.c, src/rr_types.h, src/servers.c, src/servers.h, src/status.c, src/status.h, src/thread.c, src/thread.h, configure.in, version:
	Remove the old infrastructure that theoretically could have allowed for
	multiple cache subsystems. This ability was never used, and if it should,
	the caching should probably be split into two layers, a higher level
	common one and the actual caching backends.
	src/cacheing/cache.c and src/cacheing/native/*.[ch] were repo-copied to
	src/.
	Substitute "conf.h" with <conf.h> for includes.
	Purge records a little more often (when adding records, and when
	retrieving from the cache). Handle cache_size properly when using
	purge_cent.
	Introduce some infrastructure in rr_types.[ch] for a record conflict
	checker which is to be introduced shortly to enforce cache consistency
	even in the purge_cache=off case.

2001-05-04  Thomas Moestl  <tmoestl@gmx.net>

	* src/rc/RedHat/pdnsd.in, src/rc/SuSE/pdnsd.in, src/rc/Debian/pdnsd.in:
	Revert the last commit. It breaks the rc scripts by spamming them with
	make style variable expansions.

	* src/rc/SuSE/pdnsd.in, src/rc/RedHat/pdnsd.in, src/rc/Debian/pdnsd.in, AUTHORS, THANKS:
	Fix a rc script bug spotted by Frank Elsner, and add him to AUTHORS and
	THANKS.

2001-05-01  Thomas Moestl  <tmoestl@gmx.net>

	* version: Bump version to 1.1.4p2.

	* src/pdnsd-ctl/pdnsd-ctl.c, src/status.c:
	Fix some bogons and remove some unneeded code in the pdnsd-ctl
	interface.
	Fix spelling and line length bugs.

2001-04-30  Thomas Moestl  <tmoestl@gmx.net>

	* src/pdnsd-ctl/pdnsd-ctl.c, src/conf-parse.y, src/status.c:
	Some corrections for the authrec config file and the pdnsd-ctl noauth
	support.

	* src/pdnsd-ctl/pdnsd-ctl.c:
	Fix wrong argv index (using getopt changed the indices).

	* src/pdnsd-ctl/pdnsd-ctl.c, src/conf-lex.l.in, src/conf-parse.y, src/conff.c, src/conff.h, src/dns.c, src/dns.h, src/dns_query.c, src/status.c, THANKS, version, AUTHORS:
	Accumulated changes that should go in before 1.1.4:
	- merge Andrew M. Bishop's patch that adds a server label option
	- make local records authoritative for the domain by default, and add
	  the authrec option to change this
	- add the auth keyword to the pdnsd-ctl source option to support that
	- fix a bug in the conf-parse.y grammar causing a shift/reduce conflict
	- sync up AUTHORS and THANKS: add Andrew M. Bishop, Kevin A. Burton and
	  Michael Steinl
	- bump version to 1.1.4p1

	* src/conff.c, src/main.c:
	Fix two small bugs: the wrong element of argv was used for the pidfile
	option, which could cause pdnsd to segfault, and C_INCLUDED was always
	used in slist_add, regardless of the tp parameter.

	* src/helpers.c:
	Fix a bogon discovered by Michael Steiner:  the fread() return value
	was tested against bytes, not the number of items.

	* src/hash.c, src/hash.h, src/cache.c:
	purge_cache used to walk over the cache quite inefficiently when it was
	called from add_cache. Add a lazy mode for purge_cache which uses the
	rrset_l to be efficient in this special case.
	Add some #ifdef'ed-out-by-default code to debug the hash function.

2001-04-12  Thomas Moestl  <tmoestl@gmx.net>

	* NEWS: Add NEWS entry for 1.1.3.

	* src/dns.c, src/helpers.c, src/icmp.c, contrib/Makefile.am, contrib/README, version:
	IPv6, ICMP and build fixes. It's 1.1.3 now!

	* src/debug.c, src/debug.h: Add the new debug support files.

	* src/test/clnt-test.sh, src/cache.c, src/cache.h, src/error.h, src/list.c, src/list.h, src/main.c, src/status.c, src/status.h, src/Makefile.am, src/conf-parse.y, src/conff.h, src/dns.c, src/dns_answer.c, src/dns_query.c:
	Add allocation debug support. Some small cleanups before the upcoming
	1.1.3 release.

	* src/dns_query.h, src/helpers.c, src/list.c, src/conff.c, src/dns.c, src/dns_answer.c, src/dns_query.c:
	Lots of small bugfixes, cleanups, style and spelling fixes.

	* src/test/clnt-test.sh: Fix nc arguments.

	* src/test/clnt-test.sh, src/test/srv-test.sh, src/test/test.sh:
	Add regression test scripts.

2001-04-11  Thomas Moestl  <tmoestl@gmx.net>

	* src/pdnsd-ctl/pdnsd-ctl.c, src/cache.c, src/servers.c, src/dns_answer.c, src/helpers.c, src/helpers.h, src/icmp.c, src/main.c:
	Further cleanups and bug, style and spelling fixes.

	* configure.in: Use -g again in the CFLAGS for a while.

	* version: Beta version bump.

	* src/rc/SuSE/pdnsd.in:
	killproc does not seem to take the full path, but only the process name
	(which is what one would expect).

	* src/hash.c, src/netdev.c, src/rr_types.c, src/status.c, src/conf-parse.y, src/conff.c, src/helpers.c:
	Misc. smaller fixes, and fixes on the new features. Also clean up style
	and spelling in some places.

	* src/dns_answer.c:
	Bring the glibc pthread_cleanup_push/pthread_cleanup_pop return bug
	workaround into the main tree.
	Without this, a return between those two macros would cause pdnsd
	to crash on system using a glibc between 2.1.2 and 2.2.2 (and possibly
	others). This could e.g. be cause by a TCP connect() port scan.

2001-04-10  Thomas Moestl  <tmoestl@gmx.net>

	* src/pdnsd-ctl/pdnsd-ctl.c:
	Minor fixes, direct error messages to stderr.

	* src/list.c, src/list.h: Add the new list implementations.

	* src/cache.c, src/cache.h, src/conf-parse.y, src/dns.c, src/dns_answer.c, src/dns_query.c, src/helpers.c, src/helpers.h, src/conf-lex.l.in:
	Introduce rhnlen and rhncpy and make use of it instead of kluged-up
	strcpy/strlen in the appropriate places.
	Check that incoming names contain only legal characters in
	decompress_name, return RC_FORMAT otherwise (this would result in
	wrong handling only, but not in a security hole).
	Reorganzie compose_answer and make it more correct for multiple
	questions. Get rid of the algorithm that tries to add a higher
	level name server; this might be readded in another place somewhen.
	Use some more da_* instead of hand-built lists.
	Some style cleanups.

	* src/rc/RedHat/Makefile.am:
	Add K45pdnsd links for rc6.d (reboot) and rc0.d (halt) following a
	suggestion by Stas Sergeev.

2001-04-06  Thomas Moestl  <tmoestl@gmx.net>

	* src/pdnsd-ctl/pdnsd-ctl.c, src/cache.h, src/error.h, src/helpers.c, src/helpers.h, src/main.c, src/servers.c, src/status.c, src/conf-parse.y, src/conff.c, src/conff.h, src/dns.c, src/dns.h, src/dns_answer.c, src/dns_query.c, src/Makefile.am, version:
	Bump alpha version; introduce a generic dynamic array type and make use
	of it to ged rid of some ugly casts and redundant code.
	Minor fixes.

	* src/icmp.h, src/ipvers.h, src/conff.h, src/consts.h, src/dns.h, src/dns_answer.h, src/dns_query.h, src/helpers.h:
	Use macros without an underscore as first character to protect the
	headers. Underscores are reserved and should not be used in the
	application name space.

	* src/error.h: Add PDNSD_ASSERT, change style a little.

2001-04-03  Thomas Moestl  <tmoestl@gmx.net>

	* src/hash.c, src/netdev.c, src/servers.c, src/helpers.c, src/icmp.c, src/main.c:
	Another slew of small bugfixes, minor updates and small fixes.

	* src/rr_types.c, src/consts.c:
	Update rr_types.c copyright date, consts.c should have a rcsid string.

	* src/rr_types.c: cvs add rr_types.c.

	* src/dns.h, src/helpers.h, src/ipvers.h, src/rr_types.h, src/status.h, src/conf-parse.y, src/conff.h:
	cvs add rr_types.h that got missed before, update copyright dates,
	remove some old config cruft, some minor fixups.

	* src/conff.c, src/consts.c, src/dns_answer.c, src/error.c, src/conf-lex.l.in, src/conf-parse.y:
	Update copyright dates, fix some minor bugs. Update copyright dates.
	cvs add missed consts.c.

2001-03-28  Thomas Moestl  <tmoestl@gmx.net>

	* src/cache.c, src/hash.c, src/error.c, src/servers.c, src/dns_answer.c, version:
	Bump version to 1.1.3p4
	Fix some non-critical locking issues (none of them could be fatal).
	Adjust copyright dates.

	* src/hash.c: Make the hash compare case insensitive.

2001-03-25  Thomas Moestl  <tmoestl@gmx.net>

	* contrib/Makefile.am: Add Id tag to Makefile.am

	* src/cache.c, src/dns_answer.c, src/icmp.c:
	Some more type fixes overlooked in last commit.

	* src/conf-parse.y, src/conff.h, src/dns.h, src/dns_answer.c, src/dns_query.c, src/icmp.c:
	More type cleanups. Use time_t for time specifications throughout, and
	make lengths singed longs. Cast cleanup in icmp.c to fix alpha
	unalinged access faults.

	* contrib/dhcp2pdnsd, contrib/pdnsd_dhcp.pl, contrib/save_ram.pl, contrib/Makefile.am, contrib/README, configure.in, version, Makefile.am:

2001-01-16  Thomas Moestl  <tmoestl@gmx.net>

	* src/dns_answer.c, src/icmp.c, version:
	Bump beta revision, fix a comment. Also, generate ping id's using pdnsd's

	* src/rc/SuSE/Makefile.am:
	Another one: allow rc.conf manipulation to fail for a clean
	rpm build (SuSE only).

	* file-list.base.in:
	Last-minute fix: correct filelist for rpm build to reflect the new name
	for the sample configuration.

	* version: It's 1.1.0 now.

2000-11-18  Thomas Moestl  <tmoestl@gmx.net>

2000-11-15  Thomas Moestl  <tmoestl@gmx.net>

	* src/test/Makefile.am, src/pdnsd-ctl/Makefile.am, src/cache.c, src/Makefile.am, src/dns_answer.c, src/error.h, src/icmp.c, src/icmp.h, src/main.c, src/netdev.c, src/servers.c, src/thread.c, Makefile.am, configure.in, version:
	Enabled new rr support by default (some resolvers don't seem to like not
	supported answers - not our bug, but well).
	Made some globals volatile to avoid being bitten by optimisations.

2000-11-12  Thomas Moestl  <tmoestl@gmx.net>

	* TODO, version: Called it the first beta.

2000-11-11  Thomas Moestl  <tmoestl@gmx.net>

	* src/cache.c, src/conf-lex.l.in, src/conf-parse.y, doc/pdnsd.conf.in:
	renanmed rrneg to neg in the config file.
	Misc small fixes.
	pdnsd-ctl record xxx inval will now also invalidate local records.

	* src/conf-lex.l.in, src/conf-parse.y, src/dns_answer.c, src/status.c, pdnsd.spec.in:
	Added --sysconfdir=/etc as argument to configure in the spec file.
	Implemented the new rrneg config file section.

	* src/test/Makefile.am, src/pdnsd-ctl/Makefile.am, src/pdnsd-ctl/pdnsd-ctl.c, src/cache.c, src/cache.h, src/status.c, src/status.h, TODO:
	Added the neg option to pdnsd-ctl.

	* src/cache.c, src/Makefile.am, src/conf-lex.l.in, src/consts.h, src/dns.c, src/dns.h, src/dns_answer.c, src/dns_query.c, src/helpers.c, src/main.c, configure.in:
	Assorted fixes. The new features should be stabilized by now, will
	integrate the missing few features now.
	Also actived the tcp server by default.

2000-11-07  Thomas Moestl  <tmoestl@gmx.net>

	* src/dns_answer.c, src/dns_query.c, src/icmp.c, src/ipvers.h, THANKS, TODO:
	Fixed a possible memory and socket leak reported by Erich Reitz.
	Implemented udp source address discovery for FreeBSD.

	* src/dns_query.c: Part 2 of yesterdays fix.

2000-11-06  Thomas Moestl  <tmoestl@gmx.net>

	* src/dns_query.c, version:
	Fixed a bug reported by Erich Reitz: pdnsd could leak fd's and memory if
	queries timed out.

	* src/cache.c, src/cache.h, src/Makefile.am, src/dns_answer.c, src/dns_query.c, TODO, configure.in:
	Sorted out some bugs for the new neg cacheing.

2000-11-05  Thomas Moestl  <tmoestl@gmx.net>

	* src/cache.c, src/dns_query.c, TODO:

	supported options.

	* src/conf-parse.y, src/conff.c, src/conff.h, src/consts.h, src/conf-lex.l.in:
	Added the config file options for the nefative cacheing support.

2000-11-04  Thomas Moestl  <tmoestl@gmx.net>

	* src/cache.c, src/cache.h, src/conf-parse.y, src/dns.c, src/dns_query.c, src/status.c, version:
	The new cache infrastructure for negative cacheing is in place.
	Using and testing it remains.

	* src/cache.c, src/cache.h:
	First changes to support negative cacheing. This should not break
	anything, but the cache file format will be incompatible.

	* src/main.c, src/dns_answer.c:
	init_udp_socket() and init_tcp_socket() are now called after
	daemonizing on FreeBSD, as bind wants to lock the fd which
	can cause later calls to fail after an exit.

2000-11-03  Thomas Moestl  <tmoestl@gmx.net>

	* src/dns_query.c, src/icmp.c, src/servers.c:
	Minor bugfixes and repository cleanup.

2000-11-02  Thomas Moestl  <tmoestl@gmx.net>

	* src/icmp.c, TODO, version:
	Called it 1.0.16p4. Fixed some compatability problems with the new code;
	the ipv4 implementation seems to be fairly stable, the ipv6 one needs
	some testing with dest unreach messages.

	* src/icmp.c, src/main.c:
	Rewrote large parts of the ping implementation to be more portable.

2000-11-01  Thomas Moestl  <tmoestl@gmx.net>

	* acconfig.h, configure.in, version:
	Some config fixes, version to 1.0.16p3. SOCKET_LOCKING should be
	off by default, as sendmsg can block.

	* src/pdnsd-ctl/pdnsd-ctl.c, src/error.h, configure.in:
	Removed -W* arguments from CFLAGS that were implied by -Wall.

	* src/thread.c, configure.in:
	Added some more safety tests to configure.in, and made it give
	an error on some conditions. Also made configure do poll and usleep
	detectione.

	* src/cache.h, src/test/Makefile.am, src/dns_answer.c, src/error.c, src/error.h, src/helpers.c, src/main.c, src/servers.c, src/status.c, src/thread.c, src/thread.h, src/Makefile.am:
	Code cleanup. Beautified some macros, and moved the thread
	specific things from error.[ch] over to the new thread.[ch].
	Also introduced usleep_r which tries to be thread safe for
	different Unices.

2000-10-31  Thomas Moestl  <tmoestl@gmx.net>

	* src/pdnsd-ctl/pdnsd-ctl, src/pdnsd-ctl/pdnsd-ctl.c:

	* src/pdnsd-ctl/pdnsd-ctl, src/cache.c, src/cache.h, src/error.c, src/helpers.c, src/main.c, version:
	Another set of FreeBSD compatability patches. This seems to catch
	most of the problems, and pdnsd should be useable with libc_r now.

2000-10-30  Thomas Moestl  <tmoestl@gmx.net>

	* src/pdnsd-ctl/pdnsd-ctl, src/conff.c, src/dns_answer.c, src/dns_query.c, src/helpers.c, src/icmp.c, src/main.c, AUTHORS, Makefile.am, THANKS, configure.in, version:
	FreeBSD fixes, mostly contributed by Roman Shterenzon.

2000-10-25  Thomas Moestl  <tmoestl@gmx.net>

	* src/pdnsd-ctl/Makefile.am, src/pdnsd-ctl/pdnsd-ctl:
	pdnsd-ctl was not in cvs.

	* src/dns_query.c, src/error.h, configure.in: Some fixups for 1.0.15.

2000-10-23  Thomas Moestl  <tmoestl@gmx.net>

	* src/dns_answer.c, src/dns_query.c, configure.in:
	Several fixes for pdnsd to work better when it receives error replys.

	* src/dns.c, src/dns_answer.c:
	Fixed another memory leak on an error path in dns_answer.c and did
	a pointer signedness fixup in dns.c

2000-10-21  Thomas Moestl  <tmoestl@gmx.net>

	* src/dns_answer.c, AUTHORS:
	Applied a patch by Paul Wagland that fixes some spelling mistakes

	Some bugifixes. It is now called 1.0.13. Releasing.

	* src/cache.c, src/dns_query.c, AUTHORS, NEWS:
	Updated AUTHORS and NEWS. Made destroy_cache() lock the cache so
	that no thread can access the cache afterwards (could lead to
	crashes).

	* src/helpers.c, NEWS, THANKS:
	Integrated a security fix contributed by Olaf Kirch: when
	changing user IDs, pdnsd did not reinitialize the supplementary
	group list, meaning that the process still had the privileges
	of the supplementary groups the original user was member of.

	* src/conf-lex.l.in, src/conf-parse.y, Makefile.am, TODO, version:
	Introduced the par_queries option.

	* src/dns_answer.c, src/dns_query.c, TODO:

	* src/dns_query.c, src/icmp.c, TODO:
	Got rid of the O_NONBLOCK loop in the icmp.c ping implementation.
	Beta tesing pending.

	* src/rc/Debian/Makefile.am, src/conff.c, src/conff.h, src/dns_query.c, src/dns_query.h, THANKS, TODO, acconfig.h, configure.in:
	Corrected the Debian rc script (bug reported by Michael Mller).
	Got rid of the nonblocking socket things in dns_query.c, and
	using poll/select now.
	Testing (esp. --no-poll) remains.

	* src/dns_answer.c:
	Got rid of O_NONBLOCK read loops in dns_answer.c, using poll/select
	now instead (after one issue about boundaries was cleared up).

2000-10-16  Thomas Moestl  <tmoestl@gmx.net>

	* src/rc/SuSE/Makefile.am, src/rc/RedHat/Makefile.am, src/rc/Debian/Makefile.am:
	The generated rc scripts do not need to be in the distribution.

	* src/conff.c, src/main.c:
	Fixed a server structure members in conff.c. Only delete the socket
	if we are in status pipe mode now.

2000-10-15  Thomas Moestl  <tmoestl@gmx.net>

	* src/dns_answer.c, TODO, acconfig.h:
	Added TCP timeouts to the answer code. Still need an option in the
	conf file and documentation for that (besides beta testing).

	* src/conf-lex.l.in, src/conf-parse.y, src/conff.c, src/conff.h, src/consts.h, src/dns_query.c, src/helpers.c, src/helpers.h, NEWS, TODO:
	Introduced domain inclusion/exclusion lists in the server section
	(new options include=, exclude=, policy=).

2000-10-14  Thomas Moestl  <tmoestl@gmx.net>

	* src/conf-lex.l.in, src/conf-parse.y, src/conff.c, src/conff.h, src/dns_answer.c, src/main.c, NEWS, TODO, version:
	Upped version, updated NEWS and TODO and implemented a process
	count limit.

	Added the --pdnsd-user option, and made the Debian rc script
	use it rather than trying to parse the config file itself.

2000-10-11  Thomas Moestl  <tmoestl@gmx.net>

	* src/rc/SuSE/pdnsd, src/rc/SuSE/pdnsd.in, src/rc/RedHat/pdnsd, src/rc/RedHat/pdnsd.in, src/rc/Debian/pdnsd, src/rc/Debian/pdnsd.in, AUTHORS, THANKS, configure.in:
	Added the 'configure'-able rc scripts contributed by Carsten Block
	and added him to THANKS and AUTHORS.

	* src/main.c:
	Added O_NOFOLLOW to the pidfile open() call (if it is defined)
	to prevent users creating files as the pdnsd user (using links)
	if the admin put the pidfile in a world-writeable directory
	against all good advice.
	This is not a bug fix! Admins were not, and are still not supposed
	to put the pidfile in a directory that is writeable for untrusted
	users!

2000-10-10  Thomas Moestl  <tmoestl@gmx.net>

	* THANKS: Added Milan P. Stanic to THANKS.

	flag for build.

	* src/main.c: Made the pid file handling safe for directories.

	* src/dns.c: Part II of the last fix.

	* src/dns.c:
	Fixed a nasty bug in decompress_name which would produce errors very
	rarely. That was a off-by-one bug, but on the safe side (no overflow,
	stopping one by too early).

	* src/main.c:
	Fixed several possible problems with strncat(). None of these was
	critical or involved remote data.

2000-08-08  Thomas Moestl  <tmoestl@gmx.net>

	* src/main.c: Changed FreeBSD signal latency to 250 ms.

	* src/main.c, acconfig.h:
	A set of last-minute FreeBSD fixes. pdnsd does now NEED linuxthreads on
	BSD.

2000-07-12  Thomas Moestl  <tmoestl@gmx.net>

	* dns_query.c, error.c, error.h, main.c:
	Made pdnsd ignore SIGPIPE, which seemed to be responsible for some
	crashes.
	Accept (grudgingly) SOA rr's where NS ones would be The Right Thing.

2000-07-10  Thomas Moestl  <tmoestl@gmx.net>

	* AUTHORS, THANKS, conff.c:

	queries (UDP is the default now). Made the TCP server optional.
	Fixed a authoritative record handling bug. Added pidfile support.

2000-07-07  Thomas Moestl  <tmoestl@gmx.net>

	* doc/pdnsd.conf:
	Inserted run_as="nobody"; again, it is The Right Thing and people
	should use it.

	* Makefile:
	The pdnsd cache directory is now created as nobody, since the
	default run_as in the example pdnsd.conf is also nobody.

	* doc/pdnsd.conf:
	Commented the run_as option out (people may run into permission
	problems).

	* version: Upped version to 1.0.5

	* AUTHORS, THANKS, conf.l.templ, conf.y, conff.c, conff.h, dns_answer.c, icmp.c, icmp.h, main.c, version:

	* cache.c, dns_query.c:
	Killed a bug which could cause crashes with more than 2 servers.

	* cache.c: Fixed a bug reported by Bert Frederiks that would break the
	serve_aliases option when only one character was between official
	name and alias in the /etc/hosts-style file.

2000-07-04  Thomas Moestl  <tmoestl@gmx.net>

	* pdnsd-suse.spec.templ: The SuSE spec now uses the new makefile rule.

	* Makefile, THANKS, dns_query.c, helpers.c, version:
	Added people to THANKS, fixed a bug that caused uppercase hosts/
	rr-section entries to be ignored in the cache, fixed the SuSE
	makefile for pdnsd to run_as nobody, and other small fixups.

2000-07-03  Thomas Moestl  <tmoestl@gmx.net>

	* dns_answer.c:
	First change after release of 1.0.4: The questions received

	* config.h.templ, dns_query.c:
	Fixed a possible way to get around paranoid restrictions.

	* version: Set version to 1.0.4

	* doc/pdnsd.conf: Added an entry for the paranoid option.

	* cache.c, config.h.templ, dns_answer.c, dns_query.c, ipvers.h:
	Revisions and fixups. The complete code revision is now complete.

2000-06-29  Thomas Moestl  <tmoestl@gmx.net>

	* dns_query.c: Overhaul.

	* dns_answer.c, dns_query.c, config.h.templ:

	* cache.c: Overhauled.

	* dns_query.c, error.c, helpers.c, helpers.h, ipvers.h, main.c, version, dns.c:
	Manual code overhaul. Numerous small patches, greatly simplified
	decompress_name().

2000-06-25  Thomas Moestl  <tmoestl@gmx.net>

	* config.h.templ:
	Made the C random() RNG the default (using /dev/urandom, we suck up
	too much randomness on high load).

	* error.c, error.h, icmp.c, icmp.h, main.c:
	Small cleanups. Makes the testsuite compilation easier.

	* Makefile, config.h.templ: Preparing for release of 1.0.4.

2000-06-24  Thomas Moestl  <tmoestl@gmx.net>

	* Makefile, THANKS, a-conf.sh, dns_answer.c, dns_query.c, error.c, version:
	Fixed bugs with the paranoid option, connect() timeout handling, and
	a incompatability in response handling that caused the glibc
	resolver to misunderstand error messages pdnsd generated on unknown
	query types. This bug, that was reported by James MacLean, could
	for example cause ssh to hang some time.

	* Makefile, NEWS, conf.l.templ, conf.y, conff.c, conff.h, config.h.templ, dns.c, dns_query.c, dns_query.h, helpers.c, helpers.h, icmp.c, icmp.h, main.c:
	Added the paranoid option, and modified the ping uptest so that it
	works with strict_setuid. Also made strict_setuid=on the default.
	1.0.4 should be out soon.

2000-06-23  Thomas Moestl  <tmoestl@gmx.net>

	* doc/pdnsd.conf: Added a run_as= line, which is sensible normally.

	* Makefile, conf.l.templ, conf.y, conff.c, conff.h, dns_answer.c, dns_answer.h, helpers.c, helpers.h, main.c, servers.c, status.c, version:
	Some fixups, added the run_as and strict_setuid security options.

	* THANKS: Updated.

	* AUTHORS, ipvers.h, main.c, netdev.c, version:
	Fixed some definitions for glibc2.0-users. Repaced the return at the
	end of main() with _exit(). Should not build and run OK on glibc 2.0
	boxen.
	Fixed a typo in netdev.c

	* ipvers.h:
	Fixed a typo in ipvers.h to fix compile problems on systems without
	an IPv6-supporting C library, and possible IPv6 problems using the
	status pipe.

	* error.c, version:
	Fixed a bug that could cause signals to be delivered to the wrong
	process.

2000-06-22  Thomas Moestl  <tmoestl@gmx.net>

	* version: Set version to 1.0.1.

	* cache.c, dns_answer.c, error.c, error.h, main.c, pdnsd-suse.spec.templ:
	Fixed misc issues reported by Jonathan Hudson and Joachim Dorner, one
	of them a real showstopper in cache.c.

	* Makefile, NEWS, README, cache.h, config.h.templ, version:
	Updated things for 1.0.0 and released it finally.

	* AUTHORS, THANKS: Updated THANKS and AUTHORS

	* NEWS, a-conf.sh, cache.c, conf.l.templ, conf.y, conff.c, conff.h, dns_answer.c, dns_query.c, error.c, error.h, main.c, servers.c, status.c:
	Fixed a-conf.sh and cleaned up signal handling as far as it can be
	done ;-). Added the max_ttl option.

2000-06-21  Thomas Moestl  <tmoestl@gmx.net>

	* dns_answer.c, error.c, error.h, main.c, servers.c, status.c:
	More signal fixes. This is a real pain with LinuxThreads.

	* NEWS, cache.c, dns_answer.c, error.c, error.h, helpers.c, helpers.h, main.c, servers.c, status.c, version:
	Fixups for signal handling. This is more than only a little tricky
	using the linuxthreads library. This hopefully fixes the deadlocks
	we had on signals.

2000-06-13  Thomas Moestl  <tmoestl@gmx.net>

	* AUTHORS, THANKS: Updated credits.

	* a-conf.sh:
	A primitive configure-like script intended as drop-in replacement
	until autoconf support finally comes.

	* .cvsignore, Makefile, cache.c, dns_query.c, ipvers.h, servers.c, version:
	Added a primitive configuration script as drop-in. Killed some bugs
	and changed the recently added linkdown_kluge option following
	suggestions from Daniel Smolik.

2000-06-12  Thomas Moestl  <tmoestl@gmx.net>

	* dns_query.h, exec-flex.sh, Makefile, cache.c, conf.l.templ, conf.y, conff.c, conff.h, config.h.templ, dns_query.c:
	Numerous cleanups and fixes. Implemented the linkdown_kluge option
	as proposed by Daniel Smolik. Hope to get ready for 1.0.0 know.

2000-06-10  Thomas Moestl  <tmoestl@gmx.net>

	* Makefile, NEWS, TODO, dns_answer.c:
	Modified some stuff in dns_answer.c (if no nameserver for a knot in
	the dns namespace is found now, its predecessors are tried now in
	order to return accurate authority results). This will be paid with a
	little more beta time, so the Makefile has developer switches again.
	Corrected NEWS and TODO.

	* Makefile, config.h.templ, dns_answer.c, dns_query.c, dns_query.h, hash.h, helpers.c, version:
	Removed some dead code, fixed some really minor bugs. Version is up
	to 1.0.0p7, which is hopefully the last beta.

	* Makefile, config.h.templ:
	Fixed things up for the 1.0.0 distribution version

2000-06-06  Thomas Moestl  <tmoestl@gmx.net>

	* Makefile, config.h.templ, icmp.c, netdev.c:
	Some minor comment fixes.

	* Makefile, TODO, main.c, version:
	BSD fix in Makefile and help update. It is now called 1.0.0p6. TODO
	was updated to reflect the project status.

	* dns_answer.c:
	BSD & misc fixes. pdnsd runs now nicely on my FreeBSD 4.0 box.

	* dns_answer.c, ipvers.h:
	Fixed IPv6 UDP dest address recovery. Also fixed a real stupid bug in
	ipvers.h.

	* cache.h, dns_query.c, error.h:
	Added DEBUG_MSG6 macros. Cleaned up requery handling.

	* dns.c, dns_answer.c, dns_query.c, dns_query.h:
	Fixed another heap of bugs, introduced some sanity checks, no requery
	on answers that have ra not set now.

2000-06-05  Thomas Moestl  <tmoestl@gmx.net>

	* cache.c:
	Fixed write_disk_cache.

	* cache.c, cache.h:
	Fixes for rr handling.

2000-06-04  Thomas Moestl  <tmoestl@gmx.net>

	* cache.c, dns_answer.c, dns_query.c:
	Fixes again: some missing checks for rrset existence added.

	* cache.c, dns_answer.c, helpers.c, icmp.c:
	Fixes for the new/modified code and its side effects on old code ;-)

	* ChangeLog.old, NEWS, cache.c, conf.l.templ, conf.y, conff.c, config.h.templ, dns.c, dns_answer.c, dns_query.c, error.c, hash.c, helpers.c, icmp.c, main.c, netdev.c, servers.c, status.c:
	Folded the ChangeLog and NEWS of the 0.9.x tree back in and added NEWS for the
	upcoming 1.0.0 release. Some compile fixes. Reorganized config.h.templ. Made
	the inclusion of the rcsid strings into the executable optional.

	* cache.c, dns_answer.c:
	Pile of fixes on recently added/modified code.

2000-06-03  Thomas Moestl  <tmoestl@gmx.net>

	* .cvsignore, Makefile, lex.inc.h:
	lex.inc.h should not be in CVS (it is automatically generated by
	exec-flex.sh). It should also be deleted by 'make mclean'.

	* TODO, cache.c, dns_answer.c, dns_query.c, lex.inc.h:
	rfc2181 conformance should be reached by now. Updated TODO. Bugfixing
	remains.

	* doc/html/.cvsignore, doc/html/dl.html, doc/html/doc.html, doc/html/faq.html, doc/html/index.html:
	Removed the html documentation from CVS. It is maintained separately.

	* doc/pdnsd.conf:
	Added CVS/RCS $Id$ tag.

	* cache.h, conf.l.templ, conf.y, conff.c, conff.h, config.h.templ, consts.h, dns.c, dns.h, dns_answer.c, dns_answer.h, dns_query.c, dns_query.h, error.c, error.h, exec-flex.sh, hash.c, hash.h, helpers.c, helpers.h, icmp.c, icmp.h, ipvers.h, main.c, netdev.c, netdev.h, pdnsd-redhat.spec.templ, pdnsd-suse.spec.templ, servers.c, servers.h, status.c, status.h, version, AUTHORS, INSTALL, Makefile, NEWS, README, THANKS, TODO, cache.c:
	Added CVS/RCS $Id$ tags to most files, did some cleanups, introduced
	the new rrset granularity caching. The new code is still much of beta,
	use with care.

2000-06-01  Thomas Moestl  <tmoestl@gmx.net>

	* Makefile, cache.c, hash.c, helpers.c, icmp.c, netdev.c:
	Yet another set of BSD fixes (test programs do now work for me
	under FreeBSD). Some other minor fixes.

	* Makefile, error.c, error.h, helpers.c, helpers.h:
	Transplanted kill_pdnsd from error.c to helpers.c in order to get the
	tests compiled without the thread library.

2000-05-31  Thomas Moestl  <tmoestl@gmx.net>

	* pdnsd:
	Ooops, executable got in.

	* Makefile, pdnsd:
	Added test suite programs.

	* icmp.c, netdev.c:
	All basic BSD patches have been folded in. pdnsd will now compile on
	FreeBSD with (hopefully) all features.

	* dns_answer.c, Makefile:
	Disabled udp targed address discovery for BSD builds (this sadly ist
	OS specific at least for IPv4. Must be rewritten under BSD as it is
	an RFC compatability issue under some circumstances)

	* cache.c, cache.h, conf.y, conff.c, conff.h, config.h.templ, dns_answer.c, helpers.c, icmp.c, ipvers.h, netdev.c, Makefile:
	BSD include & misc build fixes. More to follow...

	* Makefile, cache.h:
	BSD Fixes: Makefile should work with BSD make, sed command line,
	sorted out naming clash in cache.h

	* .cvsignore:
	Added ChangeLog to .cvsignore

	* THANKS, conff.c:
	Fixed a bug reported by Jonathan Hudson and added him to THANKS

	* ChangeLog.old:
	Added the pre-CVS ChangeLog.
