--- 8.1.2 released --- 380. [bug] Replaying the dynamic update log could trigger an INSIST. 379. [port] Updated IRIX port. 378. [bug] The declaration for res_freeupdrec() in resolv.h didn't use __P(). 377. [func] The server now sets SO_SNDBUF on UDP sockets. 376. [port] The malloc() implementation on many systems didn't like memcluster.c's 4KB block allocations, sometimes causing huge amounts of memory to be wasted. memcluster.c now allocates bigger chunks and makes its own 4KB blocks. 375. [bug] If more than (sizeof u_long) gets occurred for a particular memory bucket, an INSIST about puts < gets might have been erroneously trigged. Now total gets and outstanding gets are counted. 374. [port] SCO 3.2v4.2 doesn't have initgroups(), so we do not want to define CAN_CHANGE_ID. 373. [port] Updated LynxOS port. 372. [port] Updated SCO 3.2v5.0.x port. 371. [bug] "make install" could fail on some Linux systems because src/port/linux/include/net/Makefile didn't cope with an empty HFILES variable. 370. [bug] Trying to update an expired slave zone would cause the server to panic. 369. [bug] The Makefile for named-xfer didn't try to create ${DESTDIR}${DESTEXEC} if it didn't exist. 368. [bug] Interface scanning could get confused on BSD-like systems if the sa_len of the address was less than sizeof (struct sockaddr). 367. [func] The default value for the host-statistics option has been changed to "no". --- 8.1.2-T3B released --- 366. [bug] Z_AUTH was set on the cache zone do_reload(). 365. [security] Missing bounds checking in inverse query handling allowed an attacker to overwrite the server's stack. 364. [port] Added support for HP MPE. 363. [bug] named-xfer automatically restarts the transfer if the SOA changes during the transfer. There was no limit on the number of restarts, resulting in a lot of wasted effort if the SOA was constantly changing. The number of restarts is now limited. 362. [security] Requesting a zone transfer for a domain name which had a resource record of a certain format would cause the server to abort(). 361. [bug] named-xfer tries to close files named might have had open. On Solaris, sysconf(_SC_OPEN_MAX) can return RLIM_INFINITY, and if it did named-xfer would try to close all those files. named-xfer now applies an upper limit of FD_SETSIZE. 360. [port] Solaris 2.5 systems needed to be included in port_after.h to get rlim_t. --- 8.1.2-T3A released --- 359. [func] IRS group support is now controlled by the WANT_IRS_GR define in port_before.h. 358. [port] Updated IRIX port. 357. [port] Added support for QNX. 356. [func] Added -u (set user id), -g (set group id), and -t (chroot) command line options to 'named'. 355. [func] If getnetconf() fails because it can't create the socket used to get the interface list, the server will log an error if it is doing a periodic interface scan, and panic otherwise. Previous versions of the server always panicked. 354. [security] Bounds checking in named-xfer, dig, host, and nslookup had problems similar to those in item 293. Added a few more bounds checks to the server. 353. [port] Paths are no longer overridden in port_after.h, and are now generated from the various DEST paths in Makefile.set. 352. [bug] Because of problems with setting an infinite rlim_max for RLIMIT_NOFILE on some systems, previous versions of the server implemented "limit files unlimited" by setting the limit to the value returned by sysconf(_SC_OPEN_MAX). The server will now use RLIM_INFINITY on systems which allow it. 351. [port] Updated HP/UX 10.x port. 350. [bug] errno could be changed by certain signal handlers. These signal handlers now save errno on entry and restore it on exit. This changes eliminates the need for the SPURIOUS_ECHILD #define. 349. [bug] hesiod.h wasn't installed. 348. [port] Added support for LynxOS. 347. [bug] res_update() leaked the zone section it allocated. This leak no longer occurs on normal returns, but still occurs when there is an abnormal return. This will be addressed in a future fix. 346. [bug] Fix 303 fixed one thing and broke another, resulting in a nonfunctional grscan(). 345. [bug] Fix 328 was bad, causing the root zone to be purged every time a toplevel domain was reloaded. 344. [bug] The priming fix in change 330 erroneously called unsched() twice, causing a core dump if priming failed. The priming fix could also erroneously query [0.0.0.0].0. 343. [bug] The REQUIRE() in free_rrecp() was wrong, and was triggered by an unapproved update. 342. [port] Added support for SCO UNIX 3.2v5.0.4. --- 8.1.2-T2A released --- 341. [port] The LOG_CONS option to openlog() does not work as documented on some systems. The server will now use LOG_CONS only if USE_LOG_CONS is defined by the port. Currently the bsdos, decunix, freebsd, linux, and netbsd ports define USE_LOG_CONS. 340. [bug] The pid file was updated before the configuration file had been read. 339. [port] #define HAVE_GETRUSAGE for Solaris >= 2.5. 338. [func] 'host' can now print AAAA records. 337. [bug] rm_datum() erroneously set dp->d_next to NULL when savedpp wasn't NULL. Given a dynamic update operation that deleted more than one RR, this bug would cause all but one of the RRs to be leaked, and would prevent correct rollback if the update failed. 336. [bug] Make sure 's' isn't negative in res_send(). This shouldn't happen, but there have been some reports suggesting it can happen. 335. [lint] Cleaned up more gcc warnings. 334. [port] Added support for HP-UX 9.x. 333. [bug] db_glue.c didn't compile if DEBUG wasn't defined. 332. [bug] named-bootconf.pl didn't convert secondary lines that didn't contain a filename correctly. 331. [bug] If the server was configured with forwarders (but not in forward-only mode), and a query ran out of forwarders and had no nameservers, then the server would erroneously forward the request to [0.0.0.0].0. 330. [bug] If priming of the root servers failed, recovery could take a long time. If using forwarders to prime and the query expired, the first forwarder would always be skipped on subsequent attempts. The server complained about priming problems in forward-only mode, even though it doesn't matter. 329. [port] Some versions of Linux apparently need SPURIOUS_ECHILD. 328. [bug] purge_zone() didn't recurse if given the root zone, causing old data and new data for the root zone to be merged. 327. [func] Add log_check() and log_check_channel(). 326. [func] Add r_prev field to ns_updrec in . 325. [bug] Rollback of a failed dynamic update was done in FIFO order instead of LIFO order. 324. [bug] evTryAccept() closed the wrong fd if getsockname() failed. 323. [bug] eventlib didn't clear bits that had been serviced or deselected out of ctx->{rd,wr,ex}Last. 322. [bug] evDestroy() destroyed the files list before destroying the streams list. If there were any active streams, this would cause a double destroy of the streams' file objects, very likely triggering an 'insist'. 321. [bug] The correct error code for a failed asynchronous connect was not reported. It now is, at least on systems that have the SO_ERROR socket option. 320. [func] Allow multiple pending accepts. evTryAccept() now reports the errno if an error was queued. 319. [bug] The toplevel Makefile passed MARGS before $settings, which prevented overriding a port's Makefile.set from the command line. 318. [bug] The Solaris port_after.h checked for SUNOS_2_5_1 instead of SUNOS_5_5_1. 317. [unused] [This change number was allocated but not used.] 316. [bug] evTryAccept() didn't append to the done list correctly if connLast wasn't NULL. 315. [bug] The dynamic update code was incorrectly converted to clean up ns_updrec structures using the new clustered memory allocator, and this would cause an 'insist' to be triggered some time after a dynamic update had been processed. Instead of freeing the ns_updrec fields directly in ns_update.c, res_freeupdrec() was added to the resolver. 314. [bug] Adding and then deleting an RR in a single dynamic update request would crash the server. 313. [bug] The nameserver would only try zone transfers from the master that answered its SOA query. If a master for some reason can answer the SOA but not the AXFR, the other masters (if any) should be tried. 312. [security] Bounds checking in the resolver and dynamic update code had problems similar to those in item 293. Added more checks to ns_resp.c. 311. [bug] The s_wbuf in the qstream structure was leaked in certain zone transfer failures. 310. [bug] If the server ran out of memory in ns_xfr(), the subsequent connection cleanup could modify the z_numxfrs field of zone 0 instead of the zone being transferred, causing an 'insist' to be triggered later. 309. [bug] NAMELEN() could return a negative length. 308. [func] Don't log ECONNRESET in stream_getlen(). 307. [bug] include/isc/assertions.h and include/isc/list.h weren't installed. 306. [bug] Timewarping into the future would cause repeating timers to generate an event for every interval between the previous time and the new time. Repeating timers are now rescheduled based on the last event time, not their due time. Idle timers now use the last event time to compute the idle interval instead of the due time. 305. [bug] The BOUNDS_CHECK() for the 5 32-bit integers in the SOA RR was wrong. 304. [bug] lib/isc/assertions.c and lib/isc/memcluster.c did not follow the port_{before/after}.h convention. memcluster.c #included eventlib.h but did not need it. --- 8.1.2-T1A released --- 303. [bug] 'bp' in grscan() in lib/irs/lcl_gr.c was incorrectly validated, potentially causing corrupt data to be read. 302. [port] #define HAVE_GETRUSAGE for Solaris >= 2.5.1. 301. [port] Added support for Solaris 2.6. 300. [bug] The space for the pathname of named-xfer in the options block leaked. 299. [bug] wasn't in the include directory, and wasn't included before "port_after.h". 298. [func] Added "deallocate-on-exit" and "memstatistics-file" options. If deallocate-on-exit is "yes", the server will painstakingly deallocate every object it allocated. This is slower than letting the OS clean things up, but is helpful in detecting memory leaks. 297. [port] GNU libc 2.0 doesn't have so in the Linux port we now provide a stub nlist.h that includes the real nlist.h if GNU libc < 2.0 and does nothing if >= 2.0. 296. [bug] "make stdlinks" didn't "mkdir /var/obj" if /var/obj didn't exist. 295. [bug] Specifying a query-source with and address and port that the server was listening to didn't work. 294. [security] The server was willing to answer queries on its forwarding sockets. 293. [security] rrextract() did insufficient bounds checking which could cause it to crash the server by reading from an invalid memory location. 292. [bug] The server sometimes leaked the flushset (ns_resp.c). 291. [bug] The server did not detect oversized UDP packets, causing useless retries. 290. [bug] free_listen_info_list() leaked the IP matching lists; the leak occurred when the config file was reloaded. 289. [bug] [This bug number was allocated for something that turned out not to be a bug.] 288. [func] Add new list and assertion code to the ISC library. 287. [bug] "dig +sort" doesn't do anything, but was mentioned in dig's usage message, as well as in the man page. 286. [bug] Some systems have a default FD_SETSIZE much smaller than the number of files that can be opened. This could cause problems in the resolver and eventlib. FD_SETSIZE may now be set in port/*/include/fd_setsize.h. 285. [bug] If OS probing failed to match any of the supported ports, the build would try to continue with BSD 4.4 settings, with poor results in most situations. An error message is now printed if probing fails. 284. [func] The interface list is now doubly-linked. 283. [bug] The server would panic if binding to an interface that it had discovered failed. Simply not listening to the interface is a better solution. 282. [bug] The nslookup Makefile didn't prefix DESTHELP with DESTDIR when setting DEFS. 281. [bug] A socket() called in ns_main.c used PF_INET instead of AF_INET. 280. [bug] The sample named.conf used "clean-interval" instead of "cleaning-interval". 279. [bug] Some panic() messages in the IP matching code in ns_config.c were wrong. 278. [bug] Setting an interval to zero (e.g. interface-interval) eventually caused random timer destruction. 277. [bug] ns_panic() used "args" twice, but only called va_start() and va_end() once. 276. [bug] nslookup's "ls" command always listed all records instead of behaving the way its man page describes. 275. [bug] add_related_additional() leaked memory if the name was already in the related array. 274. [bug] If a timer was cleared while in executing its callback, and a new non-repeating timer was created afterwards (but still in the callback), the new timer was erroneously destroyed when the callback completed. 273. [func] Added transfer-source and host-statistics options. 272. [func] The zone number is now unsigned, allowing up to 65536 zones instead of the previous limit of 32768. 271. [func] Added evDefer(). 270. [bug] The meaning of the count returned by select() varies somewhat by operating system. Under certain circumstances, this confused eventlib's accounting and caused the server to spin. 269. [func] Added evLastEventTime(). 268. [bug] Connections weren't cleaned up when the eventlib context was destroyed. 267. [func] Added evTimeRW() and evUntimeRW() to control idle timer usage in the eventlib streams module. 266. [func] Added file descriptor table to ev_files.c to improve performance of evSelect() and evDeselect(). 265. [func] Added evHold(), evUnhold(), and evTryAccept(). 264. [func] Double-link many eventlib lists to allow faster removal of list elements. 263. [bug] Remember the previous non-blocking status of sockets given to evListen(). 262. [func] Added idle timers to eventlib. 261. [func] Added clustered memory allocator to eventlib; eventlib and named now use this allocator. 260. [func] The value of FD_SETSIZE that eventlib uses can be set by changing include/fd_setsize.h. 259. [bug] Notification of hosts on the also-notify list stopped after the first successful notification. --- 8.1.1 released --- 258. [bug] Setting SO_SNDLOWAT to 0 in ns_xfr() wasn't doing what it was intended to do, and could trigger a kernel bug on various systems derived from BSD 4.4. 257. [bug] In lib/irs/dns_ho.c, variable needsort was used in addrsort() before it was initialized. 256. [func] Ignore ECHILD from select() if SPURIOUS_ECHILD is defined. 255. [bug] The contents of libport.a needed to be in libbind.a. libport.a has been removed. 254. [install] Install library and .h files under /usr/local/bind instead of /usr/local. When the include files were in /usr/local/include, some compilers would automatically use them. The clients would typically not link with -lbind, causing unresolved symbols at link time. 253. [port] Removed change 216. 252. [port] Added port for UnixWare 2.0.x. 251. [doc] Added a documentation on installing to non-default locations. 250. [bug] The Makefiles for the binaries didn't create the installation target directories if they didn't exist. 249. [bug] Change HAS_SA_LEN to HAVE_SA_LEN in the AIX 4 port. 248. [security] The server now caches only those response records that are within the current query domain. 247. [bug] Forwarding of dynamic update requests sent to a slave for the zone is broken. This will be fixed in a future release, but in the meantime the server will simply refuse the request. Cleaned up the way some update code indicated that the request should be refused. --- 8.1.1-T2B released --- 246. [bug] process_prereq() could core dump if the name being processed wasn't known. 245. [bug] It was possible to evSelectFD the same event bits on the same fd more than once. 244. [bug] eventlib didn't decrement fdCount correctly if the eventmask matched in multiple descriptor sets. 243. [lint] Improved comment in stale(). 242. [port] Added port for OpenBSD. 241. [bug] evConnect() didn't evDeselect() the fd if connect() failed, which would cause us to call select() with a mask that included a closed file. select() would then return EBADF and trigger an 'insist'. 240. [bug] evCancelConn() closed the fd. 239. [port] SunOS doesn't supply RAND_MAX. 238. [bug] fakeaddr() called inet_aton() which wasn't strict enough. inet_pton() is now used. 237. [port] Added UnixWare 2.1.2 port. 236. [bug] The buffer in res_querydomain could overflow. 235. [bug] Fixed memory allocation problems in lib/irs/nis_gr.c. 234. [bug] evDeselectFD didn't restore the fd's previous nonblocking status correctly. 233. [func] Define SPURIOUS_ECHILD in Solaris port. Don't complain about getting ECHILD from recvfrom() if SPURIOUS_ECHILD is defined. 232. [func] named-bootconf.pl now supplies a commented out query-source directive and instructions to use it if there's a firewall involved. 231. [bug] Changed a few strdup() calls in rrextract() into savestr() calls. This prevents "related" checking from being turned off if the server runs out of memory. 230. [bug] If the query control structure was reset in ns_resp.c, we leaked the memory used for the previous qp->q_domain. 229. [func] Added the "dump-file" and "statistics-file" options. 228. [bug] named.conf called "statistics-interval" "stats-interval". 227. [func] demoted "zones changed" and "zones shrunk" messages in tryxfer() to debug level 3. --- 8.1.1-T1A released --- 226. [bug] evCancelConn trashed the connections list if the first element was removed. This could cause a seg fault or trigger an 'insist'. 225. [bug] In the "cannot redefine listen-on for port ..." error message, the port was not converted to host byte order before being printed. 224. [port] Added port for AIX 4. 223. [bug] The dynamic update routine findzone() didn't match class, so if you had two zones with the same name but different classes (e.g. IN and HS), then the wrong allow-update ACL could be used, and the wrong zone could be updated. 222. [bug] If a dynamic master zone was updated and then was made non-dynamic by removing the allow-update ACL or changing it to "none" before the zone had been dumped, then the master file would not reflect the update. 221. [func] added 'also-notify'. 220. [func] revised HAVE_GETRUSAGE ifdefs in ns_config.c. The "cannot set resource limits on this system" message on systems without HAVE_GETRUSAGE will now be logged once per options block, and the message severity is now "info" instead of "warning". 219. [bug] If the root name was encoded in a message using a compression pointer, dn_expand() would erroneously return "." as the name instead of "". 218. [bug] when gethostans() in dns_ho.c encountered a CNAME while processing a PTR query, it erroneously required that the CNAME target pass the res_hnok() test (i.e. that it be an RFC 952 hostname). 217. [bug] dnsquery didn't work because it tried to use the obsolete and broken p_query() call instead of fp_nquery(). 216. [port] set SH=bash in port/freebsd/Makefile.set. 215. [port] #define ts_sec and ts_nsec to tv_sec and tv_nsec respectively in port/freebsd/include/port_before.h. 214. [bug] the clarification TTL changes (see change 145 below) set the SOA minimum field to zero if the MSB was set. The server now leaves the SOA RR alone, but sets z_minimum to zero if the MSB is set. 213. [bug] if the SOA refresh or retry fields of a slave zone were 0, an 'insist' would be triggered when zone maintenance was performed. The server still leaves the SOA RR alone, but now imposes a minimum value for z_refresh and z_retry. 212. [func] added the clean-interval, interface-interval, and statistics-interval options. 211. [func] scan for new or deleted interfaces periodically. 210. [func] the _PATH_DUMPFILE default is now "named_dump.db". 209. [bug] and were #included after port_after.h. They are now #included before it, since they #include system header files. ns_lexer.h was #including and ns_parseutil.h. Now it #includes neither one. These changes required that the definition of struct timespec be moved from port_after.h to port_before.h in the ULTRIX, SunOS, and A/UX ports. 208. [port] removed HAVE_GETRUSAGE from the Solaris port, since Solaris only has it if a Berkeley compatibility package is installed. 207. [bug] abortxfer() always used SIGKILL, which didn't give named-xfer a chance to clean up after itself. Now abortxfer() does a SIGTERM first. If the SIGTERM isn't successful, it will use SIGKILL. 206. [bug] If two zones with the same name but different classes (e.g. IN and HS) were defined, then a zone transfer of whichever zone loaded first would work normally, but a zone transfer of the second would give only the NS and SOA RRs. 205. [bug] certain operating systems (notably Solaris) return error codes the server didn't expect, and thus treated as fatal to the interface. More error codes are now recognized. The server will now log unrecognized errors, but will not delete the interface. Certain error results from recvfrom() and accept() now panic the server. 204. [bug] stub zone transfers would fail if there were no NS records in the SOA response. The stub logic now works as intended and has more error checking. 203. [bug] we logged a failure of bind() in opensocket_d() twice. 202. [port] Linux defines AF_INET6 as 10, so we use that value in port/linux/include/port_after.h. 201. [bug] library Makefiles want to press on if linking of an individual module fails. The 'ld' rule was set up to do this, but the subsequent 'mv' rule was not, causing the make to stop if the 'ld' failed. Now the 'mv' is done only if the 'ld' succeeds. 200. [bug] the value of timeout.tv_sec was printed in SendRequest (bin/nslookup/send.c). select() on some systems (such as Linux) modifies the value of the timeout, so printing it is useless since it will always be 0. 199. [func] if s is too big for FD_SETSIZE in res_send, complain and try another nameserver. 198. [bug] sysnotify() was too strict in requiring an NS RR for the server named in the SOA MNAME field. RFCs 1996 and 2136 say the NS RR is optional. 197. [bug] The parser erroneously freed zone_name if a zone redefinition was attempted. This would cause the server to dump core if a zone appeared more than once in a configuration file. 196. [bug] Makefiles below port/*/include had "fi \" followed by "done" on the next line. This made bash 2.0 unhappy. The "fi" is now followed by a ";". 195. [port] ULTRIX's sh doesn't like an empty "for x in ..." list, and that was causing "make install" to fail in the src/port/ultrix/include/rpc directory. 194. [port] add SH variable to toplevel Makefile, document the need to use SH=bash on systems where /bin/sh is derived from "ash". 193. [bug] named-bootconf.pl could repeat end-of-line comments 192. [bug] ndc was being installed in DESTBIN instead of DESTSBIN. 191. [bug] block delivery of all other signals when in SIGTERM handler in named-xfer. 190. [bug] named-bootconf.pl didn't handle non-masked xfrnets correctly if the network was class B or class C. --- 8.1-REL released --- 189. [port] update to the port/sco50 directory rcvd from author. 188. [func] to avoid potentially confusing log messages, don't set Z_DYNAMIC if "allow-update { none; };" is specified in the config file. 187. [bug] a panic() in new_ip_match_mask() erroneously referred to the function as "new_ip_match_pattern". 186. [bug] transfers-in couldn't be set higher than the default. It may now be set as high as 20. 185. [doc] add a stub example to named.conf. 184. [bug] the usage message was out-of-date. 183. [port] some systems don't define AF_INET6, so we define it if necessary in all port_after.h --- 8.1-T5B released --- 182. [bug] fix the way bindname is allocated in hesiod_to_bind(). 181. [bug] MAXHOSTNAMELEN wasn't defined on Solaris. 180. [bug] a check for zptr != NULL in res_update was wrong. It should have been zptr == NULL. 179. [bug] sq_remove() and sq_done() were calling ns_freexfr() when any stream was removed, resulting in a panic when the server was reloaded. ns_freexfr() is now only called when a zone transfer stream is removed. --- 8.1-T4B released --- 178. [bug] if the server was reloaded and then a zone was deleted and the server reloaded again, all within a short period of time, then pending NOTIFY messages would cause the server to panic when they ran. 177. [lint] replaced BUFSIZ with a more appropriate size in several places. 176. [func] change MAXDATA to 2*MAXDNAME + 5*INT32SZ. 175. [security] libirs now limits hostnames to MAXHOSTNAMELEN characters. 174. [bug] we called ns_refreshtime() instead of ns_retrytime() in the Z_NEED_RELOAD|Z_NEED_XFER|Z_QSERIAL case in zone_maint(). 173. [bug] the server didn't clear the Z_NEED_RELOAD flag in zoneinit(). 172. [bug] if a server was a slave for a zone, and an outbound transfer ever hung or terminated unusually, regular zone maintenance would cease for the zone. 171. [port] work around a bug in the Digital UNIX 4.0B SIOCGIFCONF ioctl. 170. [func] the message logged when a zone is loaded now indicates the class of the zone. 169. [func] the message logged when a zone is removed now indicates both the type and class of the zone. 168. [bug] if a zone's type changed from master to slave on a server reload, the server erroneously deleted the new zone data as part of cleaning up the old zone data. 167. [func] when converting from wire format to printable format, represent special characters ".;\@$ by escaping them with \ instead of converting them to \DDD. 166. [bug] when a slave zone expired, it was not scheduled for immedidate maintenance. 165. [port] added port for SCO OSE 5.0.2, renamed port for SCO UNIX 3.2v4.2. 164. [func] created the "response-checks" logging category. 163. [port] don't define AF_INET6 in nameser_compat.h. 162. [bug] the server panicked if a dynamic update request was sent for a dynamic zone which had not loaded because of syntax errors in the master file. The server now returns NOTAUTH. 161. [bug] debugging messages in process_prereq() referred to process_updates() instead of process_prereq(). 160. [bug] hp was not reset after a realloc() in named-xfer.c 159. [bug] named-bootconf.pl didn't translate stub zones. 158. [lint] cast a number of "no effect" statements to void so that gcc doesn't complain when invoked with -Wall -W -Wno-unused 157. [lint] a number of uses of the %lu printf() format were converted to %u; the corresponding casts to u_long were removed. 156. [lint] converted z_deferupdcnt and z_updatecnt from int to u_int32_t. 155. [func] maint_interval is now gone; SOA sanity checking related to it is gone too. 154. [bug] in named-xfer, unsigned 32-bit integers were sometimes stored in signed 32-bit variables and then printed using a cast to u_long and printf() format %lu. This would cause problems on 64-bit systems if the MSB of the 32-bit integer was set. The variable declarations have been changed to u_int32_t, and the printf format is now %u. 153. [bug] log_open_stream() had two syslogs that said the failing function was log_vwrite() instead of log_open_stream(). 152. [lint] made class, type, and dlen in rrextract() and named-xfer.c/print_output() u_int16_t. 151. [bug] the server was incrementing nssSentFErr in the formerr: code in ns_resp.c even though it wasn't sending FORMERR to anyone. 150. [func] in "check-names response fail" mode, instead of just dropping a failing response, we now send REFUSED to the client and drop the query. 149. [bug] if there wasn't a space between the SOA minimum value and a following ')' in a master file, the server would generate an error when it tried to parse the minimum value, causing the zone load to fail. 148. [func] the list of supported syslog facilities has been increased; the following facilities may now be used, provided they're available on the system 'named' is being built on: kern, user, mail, daemon, auth, syslog, lpr, news, uucp, cron, authpriv, ftp, local[0-7]. 147. [bug] the maybe_syslog_facility, logging_opt, channel_severity, address_name, key_ref, key_stmt, acl_stmt, zone_stmt, optional_class, and size_spec rules in the parser either leaked memory or could leak memory. 146. [func] if an RR set in a reply differed from an RR set in the cache only in the TTL, we would not update the TTL of the RR set in the cache. We now update this TTL to that of the reply RR set if the reply RR set's TTL is greater. 145. [func] follow the direction of the clarification draft and treat TTLs as unsigned 32-bit integers, with a maximum value of 2^31 - 1. TTLs greater than the maximum will be converted to 0. A warning will be issued if this conversion occurs while loading a master zone or during inbound zone transfer. 144. [func] "dig version.bind. txt chaos" now returns only the version number (e.g. "8.1-T4B"). 143. [lint] fixed various mismatches between printf() format string components and their corresponding arguments. 142. [lint] SendRequest_close() in nslookup/send.c had a return type of int instead of void. 141. [port] converted bcopy() to memcpy() or memmove() as appropriate. 140. [bug] certain buffer size checking comparisons in rdata_expand() weren't working because they were checking to see if an unsigned value was < 0. 139. [func] convert a few address comparisons from == to using ina_equal(). 138. [bug] an address comparison used in marking a server as bad was done incorrectly in ns_resp.c because the comparison used = instead of ==. 137. [lint] cleaned up warnings caused by assignment used as truth-value in various source files. 136. [func] changed eventlib-related INSIST statements into INSIST_ERR, so that we can print out strerror(errno). 135. [lint] replaced _getshort() with ns_get16() and _getlong() with ns_get32() in various source files. 134. [lint] findzone() and rdata_expand() were used before they were declared in ns_update.c, and were not declared static. 133. [lint] merge_logs() was not declared in ns_func.h. 132. [lint] Linux port_after.h didn't declare daemon(). We now do so, but only if GNU libc < 2.0. 131. [lint] set_boolean_option() was not declared in ns_func.h. 130. [lint] yyparse() was not declared in ns_parser.y. 129. [lint] ns_lexer.h didn't declare lexer_end_file(). 128. [lint] db_dump.c, db_lookup.c, db_update.c, db_glue.c, db_save.c, ns_ncache.c, ns_req.c, ns_stats.c, and ns_xfr.c didn't #include 127. [lint] logging.c, ev_connects.c, ns_maint.c, ns_glue.c, ns_update.c, dig/dig.c, nslookup/list.c, nslookup/send.c, host/host.c, and dnsquery/dnsquery.c didn't #include . 126. [lint] res_update.c, heap.c, db_load.c, db_save.c, db_glue.c, ns_lexer.c, ns_forw.c, ns_maint.c, ns_req.c, ns_stats.c, ns_xfr.c, ns_glue.c, ns_config.c, ns_update.c, host/host.c, nslookup/list.c, and nslookup/getinfo.c didn't #include . 125. [lint] res_mkupdate.c, ns_update.c, nsupdate.c, ns_print.c, didn't #include . 124. [port] replaced bcmp() with memcmp(). 123. [func] while not required, it's nice to preserve the order of RRs as received when ROUND_ROBIN isn't on, so we now do so. 122. [bug] under certain improbable conditions, the server could erroneously set a maintenance timer for a master zone. When the timer went off, it would trigger the INSIST() in zone_maint(). 121. [port] replaced bzero() with memset(). 120. [func] added multiple-cnames option. 119. [bug] the timeout: code in ns_resp.c didn't clean up TCP connections. 118. [port] added port for IRIX 5.3, 6.2, 6.4 117. [bug] removed declaration of getnum_error from db_load.c, since it is now declared in ns_glob.h. 116. [bug] GNU libc 2.0 doesn't have a , so in the Linux port we now provide a stub net/route.h that includes the real if GNU libc < 2.0 and does nothing if >= 2.0. 115. [func] on Linux systems, avoid an often unnecessary 'ranlib' and the subsequent relinking of all binaries by using the 's' flag of 'ar'. 114. [bug] 'make install' didn't work on HP/UX because the path to the install script was wrong in many cases. 113. [bug] named-xfer didn't clean up properly when sent SIGTERM. 112. [bug] named-xfer didn't clean up properly if an error occured in print_output(). 111. [func] added "max-transfer-time-in" option. The server used to allow a maximum of 2 hours for an inbound zone transfer to complete. This time can now be set globally or on a per-zone basis. The parameter is the number of minutes a transfer can take. 110. [func] moved declaration of d_ns in struct databuf to improve structure alignment. 109. [bug] addname() in ns_print.c didn't write an "@" for RRs that contained a domain name which was the same as the zone origin (it wrote nothing). 108. [bug] the server didn't check for EINTR in readable() and writable() in ev_streams.c. 107. [bug] check for both EWOULDBLOCK and EAGAIN after certain system calls instead of using PORT_WOULDBLK. This fixes partial zone transfer problems reported on Sun systems. 106. [bug] db_load() couldn't read SOAs with ( ) that were only one line. 105. [bug] fixed typo in Linux Makefile.set MANROFF definition. 104. [func] move various rrset debugging messages, rm_datum, and nsfree messages to debug level 3. Moved a few rrset debugging messages to debug level 2. 103. [bug] d_rcnt could overflow; to prevent this it has been increased to 32 bits. d_mark was made unsigned and decreased to 12 bits. 102. [func] added macro DRCNTDEC to go along with DRCNTINC. 101. [bug] clean_cache() didn't count deleted RRs, so it always reported "Cleaned cache of 0 RRs". 100. [bug] heap_for_each() didn't return a status, and didn't check for a NULL context or a NULL action. heap_element() didn't set errno to EINVAL when given invalid arguments. 99. [bug] the category rule in the parser leaked memory. 98. [bug] "notify" was not recognized as a valid category name. 97. [security] zone access control wasn't applied correctly to names that didn't exist, allowing an attacker to determine whether or not a given name exists in a zone. 96. [bug] we didn't recognize certain non-fatal errno values when recvfrom() failed; this would result in us dropping an interface unnecessarily. --- 8.1-T3B released --- 95. [bug] named-bootconf.pl didn't process xfrnets correctly (if no netmask was specifed, it assumed a mask of 255.255.255.255 instead of the natural netmask for the class of the address). 94. [bug] named-bootconf.pl didn't handle lines ending in a comment. 93. [bug] if rename() failed in merge_logs(), we would return garbage instead of -1. 92. [bug] writemsg() in named-xfer.c was returning a random value instead of the number of bytes written. 91. [bug] schedretry() could set retry times in the past because it was relying on 'tt' which hadn't been updated. It now calls gettime(&tt). 90. [bug] 'tt' might not have been current when clean_cache() was called. 89. [bug] ns_lexer.h didn't #include 88. [cleanup] removed some relics of the early days of BIND 8's new logging system from the parser and ns_config.c. 87. [bug] when writing to a TCP socket, the server didn't handle errors from the write() correctly. Under the right circumstances, this will cause the server to spin. The most common trigger would be a large outbound zone transfer where the far end died. 86. [cleanup] fixed comment in dig.c that messed up font-lock mode in emacs. 85. [bug] inet_lnaof, inet_makeaddr, inet_netof, and inet_network were missing from lib/inet. 84. [func] improved log_channel creation and use by making the type more opaque. The logging API provides a more complete set of services. Added the LOG_CHANNEL_OFF flag. 83. [func] removed statistics_channel; it wasn't being used. 82. [lint] a few handler functions were declared as void (*)() instead of void (*)(void). All now have the latter declaration. 81. [port] added port for A/UX 3.1.1. 80. [port] added port for SCO UNIX 3.2v4.2. 79. [bug] when processsing slave zones during a config file reload, in the "backup file changed" (or missing) case we were calling purge_zone() and do_reload() even if we had never successfully transferred and loaded the zone. 78. [cleanup] moved writemsg() to named-xfer.c. 77. [cleanup] removed doupdate() from ns_resp.c. 76. [bug] writev() in lib/bsd would keep going if there was a partial write; this could cause incorrect output. 75. [func] added readv() to lib/bsd. 74. [bug] if evConnect() failed in tcp_send() we were aborting the server instead of just returning an error. 73. [port] automatically fix getgrgid() declaration in ULTRIX 4.5 grp.h. 72. [func] make port/*/Makefile invoke SUBDIR make in include. Add/modify include and include/sys Makefiles. 71. [port] added utimes() to lib/bsd. 70. [doc] README broken up into INSTALL, TODO, port/README. Added more info about many topics. 69. [bug] NOTIFY didn't handle an unknown NS target. E.g. if we had "test.domain NS unknown.name" and "unknown.name" was not known, NOTIFY wasn't doing an "A" query for "unknown.name". 68. [lint] tweaks to ERR() and OK() in eventlib_p.h. 67. [bug] 'ch' in main() was a char instead of an int. 66. [bug] in bin/named/Makefile, pathnames wasn't getting linked with ${LIBBIND}, ${LIBPORT}, and ${SYSLIBS}. 65. [port] automatically fix timespec in BSD/OS 2.1 includes. 64. [func] lib/isc/heap.c now includes port_before.h and port_after.h. Fix 58 (below) has been undone; with port_after.h we'll now use __ansi_realloc() from Fix 59. 63. [bug] STRIP and PS were missing from MARGS in bin/Makefile. 62. [func] RRs in the additional data section must relate to RRs in the answer and authority sections. Only certain RR types are allowed in the authority and additional data sections. 61. [bug] Dynamic update didn't understand SRV records. 60. [bug] SRV records weren't decoded properly. --- 8.1-T3A released --- 59. [bug] The IRS library also wanted an ANSI C realloc(). port/sunos now provides __ansi_realloc(). 58. [bug] SunOS didn't like heap.c doing realloc() on a NULL pointer (in ANSI C that is equivalent to malloc()), so we malloc() instead. 57. [bug] interface discovery complained about bogus interfaces on ULTRIX, SunOS, and HP/UX because SIOCGIFCONF_ADDR wasn't defined in their port_after.h. 56. [API] created lib/nameser/ns_name.c and moved a lot of the functionality from lib/resolv/res_comp.c into it. functions older than 8.1 were stubbed out, but new functions from 8.1 were just renamed/removed. 55. [bug] findzone in ns_update wasn't ignoring z_nil zones. 54. [bug] if the named-xfer exec() failed, a misleading message was printed. 53. [bug] interface discovery didn't work on NetBSD because HAVE_SA_LEN wasn't defined in port_after.h. 52. [func] log the host we got a NOTIFY message from 51. [bug] we weren't sending out NOTIFY messages if the SOA was changed as the result of a dynamic update. 50. [bug] req_notify() wasn't calling sched_zone_maint() after it called qserial_query(). 49. [bug] initial_{data,stack,core}_size and initial_num_files weren't in an #ifdef HAVE_GETRUSAGE block. 48. [func] use sysconf(_SC_OPEN_MAX) instead of getdtablesize() in all cases when USE_POSIX is defined. 47. [bug] printupdatelog() was printing the post-update serial number in the zone section instead of the pre-update serial number. 46. [bug] zp->z_serial wasn't being updated if a dynamic update changed the zone serial number. 45. [bug] the SEQ_GT test in db_update was backwards. 44. [func] merge_logs() didn't work because a 'break' wasn't removed when class and type lookups were converted to sym_ston. 43. [func] evResetTimer() added to eventlib. 42. [bug] incr_serial() doesn't need to call schedule_dump(). 41. [bug] reset_retrytimer() could clear a timer that had already been cleared. 40. [bug] some zone data structures weren't freed if the zone was removed. 39. [func] The eventlib timers module now uses a heap to implement the timer queue. 38. [bug] dynamic zones weren't dumped if they were removed from the configuration file. 37. [func] created the "load" logging category. 36. [func] find_zone now uses a hash table instead of a linear search. 35. [bug] we weren't scheduling a retry for dumps or soa serial increments that failed. 34. [func] instead of doing all NOTIFY messages five seconds after loading completes, we now spread them out over up to fifteen minutes (the maximum delay depends on how many zones there are). 33. [func] if there are too many qserials running, we'll try again in five to thirty seconds. 32. [bug] z_dumptime wasn't getting set to zero after a zone dump. 31. [func] Each zone now has a maintenance timer. sched_maint() is gone. The new programming rule: if you change zp->z_time, it's your reponsibility to ensure sched_zone_maint(zp) gets called. 30. [func] short circuit PrintTimers evPrintfs if not debugging at a level where PrintTimers would print something. 29. [bug] if a log message with a non-default category was logged to a default category channel which had print-category on, "default" was printed instead of the category name. 28. [func] the performance of the main loop has been improved. 27. [bug] NOTIFY messages weren't being delayed after a zone load. 26. [bug] the eventlib category wasn't working if the channel wasn't the default debugging channel. 25. [func] added the "maintenance" logging category. 24. [func] periodic statistics dumps are now done using an eventlib timer instead of in ns_maint(). 23. [bug] names which have multiple CNAME records are illegal, but the server was allowing them. 22. [func] convert to POSIX signals from eventlib signal handling; the eventlib API no longer provides signal support. 21. [func] converted assert() to INSIST() so that the logging system (category "insist") will be used if a consistency check fails. 20. [bug] the server could exit when it shouldn't, and without leaving a message or a core file, because it wasn't handling SIGPIPE. 19. [port] Solaris has trouble if the size of the buffer used for IP_OPTIONS processing isn't 40 bytes. 18. [bug] library Makefiles we were using 'ld' instead of ${LD}. Added LD_LIBFLAGS. 17. [bug] on at least one OS, ctime() can return NULL and this can cause problems. We now call checked_ctime() in ns_glue.c, which returns "\n" if ctime() fails. 16. [bug] some signal handlers were calling library routines which POSIX does not designate as safe for use by signal handlers. 15. [func] finished conversion to new options scheme of name checking and inbound zone transfer parameters. 14. [func] added os_change_directory(). 13. [bug] write_open() in ns_config.c wasn't checking if the file was regular before unlinking. 12. [func] added "os" logging category. 11. [bug] named-bootconf.pl used the deprecated channel name "default" instead of "default_syslog". 10. [bug] named-bootconf.pl didn't understand continuation lines. 9. [bug] remove -p from mkdep command in Makefiles for bin/named and bin/nslookup. 8. [bug] add CDEBUG to Makefiles that link using ${CC}. 7. [bug] timestamp and level were printed twice for file channels in lib/isc/logging.c. 6. [bug] off by one with on level_text subscript in lib/isc/logging.c. 5. [bug] broken channels sometimes weren't marked as broken in lib/isc/logging.c. 4. [bug] didn't set foundname=0 after try_again: in ns_resp.c. 3. [bug] update_pid_file() didn't put a newline after the pid. 2. [func] minor log message tweaks in ns_config.c. 1. [bug] zone names needed to be canonicalized in the parser. --- 8.1-T2B released ---
