1Updating Information for FreeBSD current users 2 3This file is maintained by imp@village.org. Please send new entries 4directly to him. See end of file for further details. 5 619991218: 7 sendmail.cf has moved from /etc/sendmail.cf to 8 /etc/mail/sendmail.cf. You may need to adjust /etc/rc.conf to 9 cope as well as moving sendmail.cf. 10 1119991216: 12 ntp 4.0.98 has replaced the ancient xntpd. The daemon named 13 changed from xntpd to ntpd, so you may need to update your 14 /etc/rc.conf file. The ntp.conf files are compatible with the 15 old release, unless you are using a local reference clock. 16 Details about ntp4 can be found at http://www.ntp.org/. 17 18 xntpd will be cvs removed from the repo in about a week. 19 2019991213: 21 Soren updated the ata driver. Please update to at least this 22 version before submitting bug reports. 23 2419991210: 25 The ata driver has become the primary ata/ide/atapi driver in 26 the kernel. The wd driver is obsolete. You should upgrade your 27 machine to the new ata driver. You will need to follow the 28 directions for updating the devices in the 19991205 entry. You 29 will need to update all occurances of wd to ad in your config files 30 (/etc/rc.conf, /etc/fstab, etc). A compatibility device exists 31 for wd for the time being, but once you have determined that 32 ata is working for you, transition to the new ad devices. 33 3419991205: 35 Block devices are going away. You will need to update your /dev 36 tree with a fresh copy of MAKEDEV for things to always work in 37 the future. fsck is unable to cope with dirty file systems 38 after this change, so it may work for you or it may not. 39 40 MAKEDEV should be copied from src/etc/MAKEDEV to /dev before 41 starting the following: 42 43 For N in the list of disks 44 MAKEDEV N # eg ad0 45 for M in the list of slices 46 MAKEDEV NsMa # eg ad0s1a 47 48 *** All uses of block devices must be converted to char devices. 49 *** Likely the only thing impacted is dumpdev in /etc/rc.conf 50 5119991204: 52 The dc interface has replaced al, ax, dm, pn and mx. The former 53 have been removed. 54 5519991204: 56 Support for the old 'sd' device names has been removed in 57 favor of 'da'. Please update your /etc/fstab, /etc/rc.conf 58 and any other places you might have sd names cached. 59 Generally these changes are as simple as s=/dev/sd=/dev/da=g, 60 but be careful to make sure that things are really that 61 simple. You may also need to create /dev entries for the da 62 devices as well. 63 64 MAKEDEV should be copied from src/etc/MAKEDEV to /dev before 65 starting the following: 66 67 For N in the list of da disks on your system 68 MAKEDEV daN 69 for M in the list of slices 70 MAKEDEV daNsMa 7119991203: 72 BAD144 support has been removed. Cope or replace the hardware. 73 7419991129: 75 ALPHA users take note. All klds will need to be recompiled for 76 kernels build after this date. It is a good time to update since 77 pal.s will be going away soon. 78 7919991126: 80 MFS_ROOT and MFS_ROOT_SIZE are gone, replaced by MD_ROOT and 81 MD_ROOT_SIZE options in the md driver. md driver now deals with 82 the hacks. You should add md driver to kerneles that have 83 MFS_ROOT, et al. See GENERIC or LINT for details. 84 8519991125: 86 The ep changed a while ago and can no longer be used with hard 87 wired addresses in the config file. 88 8919991122: 90 The bridge drivers for sound cards have been committed. Please 91 see LINT for instructions for your card, if it still works at 92 all. 93 9419991113: 95 Gcc 2.95.2 is now the default compiler. 96 9719991015: 98 PCCARD has been updated to attach pcic to the isa bus. Therefore 99 you will need to modify kernel config files that have pcic/card 100 in them as follows: 101 controller pcic0 at isa? 102 controller pcic1 at isa? 103 controller card0 104 10519990929: 106 The sigset_t datatype has been changed from an integral type 107 to a compound type and can hold 128 signals. Syscalls directly 108 or indirectly using the new sigset_t have been added as to 109 maintain compatibility with existing binaries. A new kernel must 110 be made and installed and booted with before a make world can 111 be done. 112 11319990919: 114 New jail syscall format requires recompilation of jail(8) with 115 fresh headers installed (or a make world will do it for you). 116 11719990914: 118 Matt Dillon checked in many vm related things and sent a heads up 119 to -current urging caution and to report vm problems to him. 120 As of the 19th, no killer problems have been reported, but you 121 have been warned. 122 12319990908: 124 The new miibus has been added to the system. If you are using 125 the dm, rl, sf, sis, ste, tl, wb or xl drivers, you need to 126 add "controller miibus0" to your config file. 127 12819990905: 129 /var/cron/log has been moved to /var/log/cron to get all the 130 log files in one place. 131 13219990831: 133 tn3270 has been removed from the base system and added as a port. 134 13519990830: 136 User-visible TCP timers are now expressed in units of 1ms, instead 137 of 500ms, so if you've customized any timer values under 138 ``net.inet.tcp'', multiply them by 500 to preserve TCP's behavior. 139 14019990828: 141 RCS Id tags changed to FreeBSD. This will cause huge cvsup 142 updates. 143 14419990821: 145 On 28-May-1999 libreadline was upgraded from readline-2.2 to 146 readline-4.0. At that time the shared library major version 147 number was bumped from "3" to "4". It has been deemed that 148 the interface change between readline-2.2 and readline-4.0 was 149 not sufficient to warrant the version number bump. 150 151 Thus I have reverted it back to "3". You will need to perform 152 the below immediately before your next ``make world'': 153 cd /usr/lib 154 ls -l libreadline.so.4 155 (if you have /usr/lib/libreadline.so.4) 156 mv libreadline.so.4 libreadline.so.3 157 rm -f libreadline.so 158 ln -s libreadline.so.3 libreadline.so 159 16019990801: 161 Changes to the pccardd kernel interface require that you recompile 162 pccardd for new kernel. 163 16419980725: 165 The ipfw interface to the kernel has changed. You will need to 166 recompile ipfw programs for the new kernel. 167 16819990715: 169 The bpfilter device has been renamed to bpf. You will need to 170 change your config files in order to enable this in newer kernels. 171 17219990704: 173 src/contrib/sys/softupdates is moving to 174 src/sys/contrib/softupdates. Update your symbolic links/etc. 175 17619990702: 177 Major changes have been made to vinum and its interface. See 178 the man page (vinum(8)) for details. Look at the concat, 179 mirror and stripe commands, as well as the SIMPLIFIED 180 CONFIGURATION section. 181 18219990628: 183 Newsyslog.conf has had a minor, but potentially dangerous, 184 change to its username/group syntax. The old syntax was 185 user.group, while the new syntax is user:group. 186 18719990627: 188 Inetd wrapping default has changed. Please see the updated 189 man page for details. 190 19119990623: 192 Compaq Smart Raid driver committed as ida. 193 19419990622: 195 The second phase of syscons cleanup has happened. Some 196 functionality has been made optional. For details, see 197 http://www.freebsd.org/~yokota/sc_update-June.txt 198 Everyone will need to re-config(8) their kernels, but old 199 binaries will work with the new kernel. 200 20119990620: 202 IPFW uid/gid-based filtering support has been committed. This 203 breaks binary compatibility with previous copies of 204 ipfw(8). Any utilities using the ioctl()s of ipfw (especially 205 ipfw(8)) need to be recompiled with the newest headers 206 installed. 207 20819990618: 209 Inetd now wraps all stream-based services, including internals. 210 Syslog "severity" options are honoured. Installed syslog.conf 211 and hosts.allow should be checked. 212 21319990509: 214 Most of the problems with newbus have been corrected, but 215 it is still current and evolving. 216 217 libcam's ABI has changed. You must recompile the world and 218 any ports that use it. 219 22019990427: 221 Massive changes to SMP went into the tree that should speed 222 things up. However, if you experience problems with SMP 223 machines, you can back off to the PRE_SMP_VMSHARE tag in the 224 CVS repository (or run an MP kernel). 225 22619990420: 227 Pccardd and the pccard bus in general seem to be broken or 228 most people. Soren has patches to make it better for some, 229 but not all people. Work is underway to make it better for 230 all people. 231 23219990416: 233 new bus changes integrated into -current. Many problems were 234 initially reported, but most have been fixed. You'll need a 235 new config and to tweak your kernel config file the way that 236 GENERIC was tweaked. Keep a copy of your old kernel when 237 upgrading in case your new kernel doesn't work (and report the 238 breakage to current@freebsd.org). 239 240 As of 19990421 the remaining problems/quirks are 241 242 o sio no longer supports pnp nor pccard. This will be corrected, 243 but the new pccard code needs to be completed. 244 o Some of the sound drivers broke for some people. It seems 245 inconsistant as to who/what/when/where things broke. 246 o Duplicate device entries in your config do not work. Previously 247 they were silently ignored. psm0 seems to be the most common 248 duplicate choice, although some reports have come in from people 249 that wired their scsi disk entries. 250 o You must move the keyboard and mouse attachments from the 251 isa bus to the atkbdc bus. See GENERIC for details. 252 o Machines with multiple host-pci bridges (Intel 450NX) will not 253 probe the second pci bus. 254 o Some probe ordering may have changed, so device naming may change 255 with the new kernel. If you have multiple devices, please double 256 check to make sure they didn't move. This is especially true 257 for cards on different buses. 258 o The bus attachment for vga0 is always isa0 and never pci0 when 259 it is in fact a pci card. It is safe to ignore this. 260 o The format of the boot messages has changed (and is not 261 guaranteed to be constant for a while) so you may see this 262 in some shell scripts that diff dmesg from day to day as well 263 as scripts that parse dmesg output. 264 26519990414: 266 cc -aout sometimes has problems compiling with -g, remove -g 267 from those compilation units affected until this is corrected. 268 269 cc -aout has problems with producing some threaded libraries, 270 so make world -DWANT_AOUT is not functional at this time. 271 272 Since make world for a.out isn't functional, you cannot do 273 make aout-to-elf from a pre-egcs a.out system. To work around 274 this problem, make aout-to-elf using 3.1-stable first (or a 275 pre egcs -current) and then a simple make world will take you 276 the rest of the way with a -current source base. 277 27819990413: 279 Make -j works again for make world. As always, use it with 280 care, and be sure to try a make world w/o -j before reporting 281 problems (that is, know if the problem exists w/o -j before 282 reporting the problem with -j). 283 28419990413: 285 Note cc -aout, which had been broken since the conversion to 286 egcs, now supposedly works. If you have rebuilt things like 287 XFree86 a.out libraries, you should rebuild them again or 288 progams that use them, including netscape, will fail to work. 289 29019990409: 291 NOTE: New c++ compiler cannot be used with c++ binaries from 292 the old compiler and vice versa. 293 29419990408: 295 In recent days egcs has been imported into the tree. A number 296 of problems have been discussed in -current. Here is a highlight 297 of a few of the more common ones. With the exception of make 298 -j n, they have been claimed to have been fixed. 299 300 c++ is broken after make world: This is correct. Because we 301 changed compilers two make worlds are necessary to get C++ 302 working again. The code generated by the old compiler and new 303 compiler are not compatible, so things wind up being 304 undefined. 305 306 cpp is broken in make world: There was a window where cpp 307 would be built incorrectly. The fix for this is 308 cd src/gnu/usr.bin/cc 309 make clean 310 make all 311 make install 312 and this should correct your problems. See the -current 313 archives for a version of this that does moer cleaning. 314 315 Make -j n doesn't work. Work contiunes to make this work, 316 I've seen no reports of success as of April 7th. 317 31819990329: 319 Previously, one would define "NOAOUT" to keep from building 320 the legacy a.out bits. Now one would define "WANT_AOUT" to 321 build them. 322 32319990316: 324 The name of the old wd.c and atapi.c based CDROM driver has 325 been changed back to wcd. So update your config file to use 326 "device wcd" instead of "device acd". 327 32819990314: 329 For those of you using the VN device as a loadable module, 330 please be aware that the new VN device has been committed to 331 -4.x and cannot yet be used as a loadable module. This will 332 be fixed in the future. 333 33419990309: 335 New loader.rc mechanism. Please see src/sys/boot/README for 336 details. 337 33819990225: 339 struct proc size changed. Recompile kernel and the 340 usual suspects. Make world if in doubt. 341 34219990214: 343 The nlpt driver has changed names back to be the lpt driver. 344 See ppbus(4) or http://www.freebsd.org/~nsouch/ppbus.html 345 for proper configuration details. 346 34719990210: 348 The 'lpt' driver is now obsolete. Replace it with the 'nlpt' 349 driver and 'ppbus' controller combination. 350 35119990209: 352 New devstat API requires recompilation of libdevstat, systat, 353 iostat, vmstat and rpc.rstatd. A new kernel is also required. 354 make world + building a kernel should do all of this. Any 355 ports that use devstat need to be recompiled as well. 356 35719990125: 358 Linux threads options has gone away (they are now standard in 359 the FreeBSD kernel). A recompile of all libkvm using programs 360 is in order (or better yet a make world). 361 36219990122: 363 On or about this date there was a small window when the boot 364 blocks had some minor problems which seemed to force one to 365 edit /etc/fstab. This has been corrected, if you are seeing this 366 problem, please rebuild and reinstall your boot blocks. 367 36819990121: 369 Vinum has changed. The "vinum read" command has changed. For 370 updates, please see 371 372http://www.freebsd.org/cgi/getmsg.cgi?fetch=800363+0+current/freebsd-current 373 374 for details. 375 376 Matt Dillon committed a boatload of VM changes, for 377 information please see 378 379http://www.freebsd.org/cgi/getmsg.cgi?fetch=886676+0+current/freebsd-current 380 or 381http://www.freebsd.org/cgi/getmsg.cgi?fetch=827400+0+current/freebsd-current 382 383 for details. These changes will likely not impact anybody, 384 but large chagnes to the VM need at least a heads up. 385 38619990120: 387 Stable branch created. You might want to consider using this 388 branch. It is tagged with RELENG_3. 389 39019990119: 391 More work on the syscons driver has been committed. Since 392 files moved around, you will need to reconfigure your kernel, 393 and make clean; make depend before rebuilding the kernel. No 394 config file changes are needed. 395 39619990111: 397 New keyboard and video card drivers are introduced as the first 398 stage of console driver reorganization. You are required to 399 update the kernel configuration file and rebuild the kernel. 400 kbdcontrol, vidcontrol, and screen savers also need recompilation. 401 The instruction can be found in 402 403 http://www.freebsd.org/~yokota/sc_update.txt 404 405 It has notes on splash screen too. 406 40719990106: 408 Robert Nordier was kind enough to make this page to enable people to 409 install the new bootblocks: 410 411 http://www.freebsd.org/~rnordier/boot.txt 412 413 When updating to ELF, make sure that you have updated your 414 /etc/rc files which have different ldconfig invocations for 415 elf and aout. Otherwise things like X will stop working with 416 messages about being unable to find library files. The 417 mergemaster utility in ports/sysutils/mergemaster helps to 418 keep critical files like this in sync, and its use is 419 recommended. 420 42119990104: 422 Information about ELF day (see 19981230) can be found in 423 424 http://www.freebsd.org/~peter/elfday.html 425 426 about the upcoming change, its motivations and instructions 427 for doing the upgrade. 428 42919981230: 430 You should install new bootblocks now. The ELF kernel will 431 become default soon. In addition, you'll need to upgrade 432 your userland programs to ELF before then as well. Use 433 make aout-to-elf to upgrade your userland programs (old 434 a.out programs in, for example, /usr/local/bin will 435 continue to work, even after the upgrade). See src/Makefile 436 for more details. 437 43819981224: 439 The old wcd driver has been deleted from the kernel. The 440 driver that replaces it is named acd. You'll need to change 441 this in your configuration files. 442 443 Failure to do this will result in "ATAPI CD-ROMs not 444 configured" at boot time. 445 446 The floppy tape driver (ft) has been removed from the kernel, 447 with no replacement driver. 448 44919981202: 450 New groups from 19981201 commented out of mtree, so they 451 aren't strictly needed, but still a good idea to have. 452 45319981201: 454 New user/group added: bind. From src/etc/master.passwd and 455 src/etc/group: 456 % grep <newstuff> /usr/src/etc/group 457 bind:*:53: 458 % grep <newstuff> /usr/src/etc/master.passwd 459 tty:*:4:65533::0:0:Tty Sandbox:/:/sbin/nologin 460 kmem:*:5:65533::0:0:KMem Sandbox:/:/sbin/nologin 461 bind:*:53:53::0:0:Bind Sandbox:/:/sbin/nologin 462 46319981118: 464 PAM integrated into the tree. Requires new /etc/pam.conf file 465 to silence warnings from authentication programs (login, etc). 466 See src/etc/pam.conf for a sample. 467 468This file contains a list, in reverse chronologocal order, of major 469breakages in tracking -current. Not all things will be listed here, 470and it only starts on November 18, 1998. If you have an earlier 471version of FreeBSD, you are on your own to get to November 18, 1998. 472 473Please filter your entries through Warner (imp@village.org) so that 474the style, formatting, etc of this file can be maintained. 475 476$FreeBSD$ 477
