UPDATING revision 56914
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. For commonly 5done items, please see the end of the file. Search for COMMON ITEMS: 6 720000129: 8 {set,get}flags have been added to the tree for rather dubious 9 reasons. An unintended side effect of this is that you must 10 rebuild install before the rest of the world. 11 12 cd src/usr.bin/xinstall 13 make depend all install clean 14 15 before make world or buildworld. This issue may be resolved 16 before 4.0 goes out. 17 1820000124: 19 The default way that virtual tables in our default C++ 20 compiler has changed. We used to use THUNKS for virtual 21 inheritance. Unfortunately there are bugs that The GCC 22 developers thought would be fixed in GCC 2.95. However it 23 isn't. 24 25 After this change existing applications written in C++ may 26 give errors like below when you try to run them: 27 28/usr/libexec/ld-elf.so.1: /usr/lib/libstdc++.so.3: Undefined symbol "__vt_7filebuf" 29 30 The only fix is to rebuild the application and any C++ 31 libraries used. 32 3320000124: 34 The management of next_writeable has been move from the 35 kernel to userspace. This means that the burncd command 36 must be in sync with the kernel. So make world is your 37 friend. 38 3920000117: 40 GNU texinfo upgraded to 4.0. It is recommended that you use 41 make buildworld to update. 42 4320000117: 44 CAM_VERSION has been increased. Recompile all programs that 45 depend on it (tosha, camcontrol, etc) when moving to kernels 46 past this date. 47 4820000115: 49 pccard ioctls changed with a commit to have the kernel tell 50 pccardd which device it created, rather than having pccardd 51 dictate it to the kernel. Recompile kernel and 52 pccardd/pccardc together. pccardd/pccardc rely on a kernel 53 Makefile that must be installed prior to building them. Make 54 world will automatically take care of this issue, but you need 55 to know if you are building by hand. 56 5720000109: 58 Your kernel config files need to be changed to s/controller/device/ 59 in them. You will need a new version of config to do this. 60 6120000107: 62 chown & chgrp moved again 63 64 This is a heads up to let you know that you need to 65 rm -f /sbin/chown /bin/chgrp 66 after your next `make world'. Additionally you need to install 67 a new /dev/MAKEDEV (mergemaster(8) will assist you in this). 68 6920000107: 70 SHA-1 password support gone 71 72 As warned yesterday, I've just removed the ability for 73 libcrypt to understand SHA-1 passwords. This was present but 74 undocumented in the tree for the past few months and was 75 removed so it can be reimplemented properly as part of a 76 revamped libcrypt at a later date. Anyone who was actually 77 making use of the feature will have to update their passwords 78 back to MD5 before they reinstall the library. 79 8020000106: 81 ioctl numbers changed for dvdio ioctls. You will need to recompile 82 anything that uses them. wormcontrol has been deprecated in 83 favor of burncd. 84 8519991223: 86 Building linux and svr4 compatibility into the kernel now 87 requires /usr/bin/genassym. Go to /usr/src/usr.bin/genassym, 88 do "make obj ; make clean depend all install" before building 89 your kernel. 90 9119991218: 92 sendmail.cf has moved from /etc/sendmail.cf to 93 /etc/mail/sendmail.cf. You may need to adjust /etc/rc.conf 94 and /etc/rc to cope as well as moving sendmail.cf. 95 9619991216: 97 ntp 4.0.98 has replaced the ancient xntpd. The daemon name 98 changed from xntpd to ntpd, so you may need to update your 99 /etc/rc.conf file. The ntp.conf files are compatible with the 100 old release, unless you are using a local reference clock. 101 Details about ntp4 can be found at http://www.ntp.org/. 102 103 xntpd will be cvs removed from the repo in about a week. 104 10519991213: 106 Soren updated the ata driver. Please update to at least this 107 version before submitting bug reports. 108 10919991210: 110 The ata driver has become the primary ata/ide/atapi driver in 111 the kernel. The wd driver is obsolete. You should upgrade your 112 machine to the new ata driver. You will need to follow the 113 directions for updating the devices in the 19991205 entry. You 114 will need to update all occurances of wd to ad in your config files 115 (/etc/rc.conf, /etc/fstab, etc). A compatibility device exists 116 for wd for the time being, but once you have determined that 117 ata is working for you, transition to the new ad devices. 118 11919991205: 120 Block devices are going away. You will need to update your /dev 121 tree with a fresh copy of MAKEDEV for things to always work in 122 the future. fsck is unable to cope with dirty file systems 123 after this change, so it may work for you or it may not. 124 125 MAKEDEV should be copied from src/etc/MAKEDEV to /dev before 126 starting the following: 127 128 For N in the list of disks 129 MAKEDEV N # eg ad0 130 for M in the list of slices 131 MAKEDEV NsMa # eg ad0s1a 132 133 *** All uses of block devices must be converted to char devices. 134 *** Likely the only thing impacted is dumpdev in /etc/rc.conf 135 13619991204: 137 The dc interface has replaced al, ax, dm, pn and mx. The former 138 have been removed. 139 14019991204: 141 Support for the old 'sd' device names has been removed in 142 favor of 'da'. Please update your /etc/fstab, /etc/rc.conf 143 and any other places you might have sd names cached. 144 Generally these changes are as simple as s=/dev/sd=/dev/da=g, 145 but be careful to make sure that things are really that 146 simple. You may also need to create /dev entries for the da 147 devices as well. 148 149 MAKEDEV should be copied from src/etc/MAKEDEV to /dev before 150 starting the following: 151 152 For N in the list of da disks on your system 153 MAKEDEV daN 154 for M in the list of slices 155 MAKEDEV daNsMa 15619991203: 157 BAD144 support has been removed. Cope or replace the hardware. 158 15919991129: 160 ALPHA users take note. All klds will need to be recompiled for 161 kernels build after this date. It is a good time to update since 162 pal.s will be going away soon. 163 16419991126: 165 MFS_ROOT and MFS_ROOT_SIZE are gone, replaced by MD_ROOT and 166 MD_ROOT_SIZE options in the md driver. md driver now deals with 167 the hacks. You should add md driver to kerneles that have 168 MFS_ROOT, et al. See GENERIC or LINT for details. 169 17019991125: 171 The ep changed a while ago and can no longer be used with hard 172 wired addresses in the config file. 173 17419991122: 175 The bridge drivers for sound cards have been committed. Please 176 see LINT for instructions for your card, if it still works at 177 all. 178 17919991113: 180 Gcc 2.95.2 is now the default compiler. 181 18219991030: 183 /etc/radius.conf file format has changed.The format change is 184 as follows. Each server line in the file should now begin 185 with a new field containing either "auth" for RADIUS 186 authentication, or "acct" for RADIUS accounting. Formerly 187 only authentication was supported. If the first field isn't 188 "auth" or "acct" then the code assumes that "auth" is 189 intended. (That's the compatibility hack.) 190 19119991015: 192 PCCARD has been updated to attach pcic to the isa bus. Therefore 193 you will need to modify kernel config files that have pcic/card 194 in them as follows: 195 controller pcic0 at isa? 196 controller pcic1 at isa? 197 controller card0 198 19919990929: 200 The sigset_t datatype has been changed from an integral type 201 to a compound type and can hold 128 signals. Syscalls directly 202 or indirectly using the new sigset_t have been added as to 203 maintain compatibility with existing binaries. A new kernel must 204 be made and installed and booted with before a make world can 205 be done. 206 20719990919: 208 New jail syscall format requires recompilation of jail(8) with 209 fresh headers installed (or a make world will do it for you). 210 21119990914: 212 Matt Dillon checked in many vm related things and sent a heads up 213 to -current urging caution and to report vm problems to him. 214 As of the 19th, no killer problems have been reported, but you 215 have been warned. 216 21719990908: 218 The new miibus has been added to the system. If you are using 219 the dm, rl, sf, sis, ste, tl, wb or xl drivers, you need to 220 add "controller miibus0" to your config file. 221 22219990905: 223 /var/cron/log has been moved to /var/log/cron to get all the 224 log files in one place. 225 22619990831: 227 tn3270 has been removed from the base system and added as a port. 228 22919990830: 230 User-visible TCP timers are now expressed in units of 1ms, instead 231 of 500ms, so if you've customized any timer values under 232 ``net.inet.tcp'', multiply them by 500 to preserve TCP's behavior. 233 23419990828: 235 RCS Id tags changed to FreeBSD. This will cause huge cvsup 236 updates. 237 23819990821: 239 On 28-May-1999 libreadline was upgraded from readline-2.2 to 240 readline-4.0. At that time the shared library major version 241 number was bumped from "3" to "4". It has been deemed that 242 the interface change between readline-2.2 and readline-4.0 was 243 not sufficient to warrant the version number bump. 244 245 Thus I have reverted it back to "3". You will need to perform 246 the below immediately before your next ``make world'': 247 cd /usr/lib 248 ls -l libreadline.so.4 249 (if you have /usr/lib/libreadline.so.4) 250 mv libreadline.so.4 libreadline.so.3 251 rm -f libreadline.so 252 ln -s libreadline.so.3 libreadline.so 253 25419990801: 255 Changes to the pccardd kernel interface require that you recompile 256 pccardd for new kernel. 257 25819980725: 259 The ipfw interface to the kernel has changed. You will need to 260 recompile ipfw programs for the new kernel. 261 26219990715: 263 The bpfilter device has been renamed to bpf. You will need to 264 change your config files in order to enable this in newer kernels. 265 26619990704: 267 src/contrib/sys/softupdates is moving to 268 src/sys/contrib/softupdates. Update your symbolic links/etc. 269 27019990702: 271 Major changes have been made to vinum and its interface. See 272 the man page (vinum(8)) for details. Look at the concat, 273 mirror and stripe commands, as well as the SIMPLIFIED 274 CONFIGURATION section. 275 27619990628: 277 Newsyslog.conf has had a minor, but potentially dangerous, 278 change to its username/group syntax. The old syntax was 279 user.group, while the new syntax is user:group. 280 28119990627: 282 Inetd wrapping default has changed. Please see the updated 283 man page for details. 284 28519990623: 286 Compaq Smart Raid driver committed as ida. 287 28819990622: 289 The second phase of syscons cleanup has happened. Some 290 functionality has been made optional. For details, see 291 http://www.freebsd.org/~yokota/sc_update-June.txt 292 Everyone will need to re-config(8) their kernels, but old 293 binaries will work with the new kernel. 294 29519990620: 296 IPFW uid/gid-based filtering support has been committed. This 297 breaks binary compatibility with previous copies of 298 ipfw(8). Any utilities using the ioctl()s of ipfw (especially 299 ipfw(8)) need to be recompiled with the newest headers 300 installed. 301 30219990618: 303 Inetd now wraps all stream-based services, including internals. 304 Syslog "severity" options are honoured. Installed syslog.conf 305 and hosts.allow should be checked. 306 30719990509: 308 Most of the problems with newbus have been corrected, but 309 it is still current and evolving. 310 311 libcam's ABI has changed. You must recompile the world and 312 any ports that use it. 313 31419990427: 315 Massive changes to SMP went into the tree that should speed 316 things up. However, if you experience problems with SMP 317 machines, you can back off to the PRE_SMP_VMSHARE tag in the 318 CVS repository (or run an MP kernel). 319 32019990420: 321 Pccardd and the pccard bus in general seem to be broken or 322 most people. Soren has patches to make it better for some, 323 but not all people. Work is underway to make it better for 324 all people. 325 32619990416: 327 new bus changes integrated into -current. Many problems were 328 initially reported, but most have been fixed. You'll need a 329 new config and to tweak your kernel config file the way that 330 GENERIC was tweaked. Keep a copy of your old kernel when 331 upgrading in case your new kernel doesn't work (and report the 332 breakage to current@freebsd.org). 333 334 As of 19990421 the remaining problems/quirks are 335 336 o sio no longer supports pnp nor pccard. This will be corrected, 337 but the new pccard code needs to be completed. 338 o Some of the sound drivers broke for some people. It seems 339 inconsistant as to who/what/when/where things broke. 340 o Duplicate device entries in your config do not work. Previously 341 they were silently ignored. psm0 seems to be the most common 342 duplicate choice, although some reports have come in from people 343 that wired their scsi disk entries. 344 o You must move the keyboard and mouse attachments from the 345 isa bus to the atkbdc bus. See GENERIC for details. 346 o Machines with multiple host-pci bridges (Intel 450NX) will not 347 probe the second pci bus. 348 o Some probe ordering may have changed, so device naming may change 349 with the new kernel. If you have multiple devices, please double 350 check to make sure they didn't move. This is especially true 351 for cards on different buses. 352 o The bus attachment for vga0 is always isa0 and never pci0 when 353 it is in fact a pci card. It is safe to ignore this. 354 o The format of the boot messages has changed (and is not 355 guaranteed to be constant for a while) so you may see this 356 in some shell scripts that diff dmesg from day to day as well 357 as scripts that parse dmesg output. 358 35919990414: 360 cc -aout sometimes has problems compiling with -g, remove -g 361 from those compilation units affected until this is corrected. 362 363 cc -aout has problems with producing some threaded libraries, 364 so make world -DWANT_AOUT is not functional at this time. 365 366 Since make world for a.out isn't functional, you cannot do 367 make aout-to-elf from a pre-egcs a.out system. To work around 368 this problem, make aout-to-elf using 3.1-stable first (or a 369 pre egcs -current) and then a simple make world will take you 370 the rest of the way with a -current source base. 371 37219990413: 373 Make -j works again for make world. As always, use it with 374 care, and be sure to try a make world w/o -j before reporting 375 problems (that is, know if the problem exists w/o -j before 376 reporting the problem with -j). 377 37819990413: 379 Note cc -aout, which had been broken since the conversion to 380 egcs, now supposedly works. If you have rebuilt things like 381 XFree86 a.out libraries, you should rebuild them again or 382 progams that use them, including netscape, will fail to work. 383 38419990409: 385 NOTE: New c++ compiler cannot be used with c++ binaries from 386 the old compiler and vice versa. 387 38819990408: 389 In recent days egcs has been imported into the tree. A number 390 of problems have been discussed in -current. Here is a highlight 391 of a few of the more common ones. With the exception of make 392 -j n, they have been claimed to have been fixed. 393 394 c++ is broken after make world: This is correct. Because we 395 changed compilers two make worlds are necessary to get C++ 396 working again. The code generated by the old compiler and new 397 compiler are not compatible, so things wind up being 398 undefined. 399 400 cpp is broken in make world: There was a window where cpp 401 would be built incorrectly. The fix for this is 402 cd src/gnu/usr.bin/cc 403 make clean 404 make all 405 make install 406 and this should correct your problems. See the -current 407 archives for a version of this that does moer cleaning. 408 409 Make -j n doesn't work. Work contiunes to make this work, 410 I've seen no reports of success as of April 7th. 411 41219990329: 413 Previously, one would define "NOAOUT" to keep from building 414 the legacy a.out bits. Now one would define "WANT_AOUT" to 415 build them. 416 41719990316: 418 The name of the old wd.c and atapi.c based CDROM driver has 419 been changed back to wcd. So update your config file to use 420 "device wcd" instead of "device acd". 421 42219990314: 423 For those of you using the VN device as a loadable module, 424 please be aware that the new VN device has been committed to 425 -4.x and cannot yet be used as a loadable module. This will 426 be fixed in the future. 427 42819990309: 429 New loader.rc mechanism. Please see src/sys/boot/README for 430 details. 431 43219990225: 433 struct proc size changed. Recompile kernel and the 434 usual suspects. Make world if in doubt. 435 43619990214: 437 The nlpt driver has changed names back to be the lpt driver. 438 See ppbus(4) or http://www.freebsd.org/~nsouch/ppbus.html 439 for proper configuration details. 440 44119990210: 442 The 'lpt' driver is now obsolete. Replace it with the 'nlpt' 443 driver and 'ppbus' controller combination. 444 44519990209: 446 New devstat API requires recompilation of libdevstat, systat, 447 iostat, vmstat and rpc.rstatd. A new kernel is also required. 448 make world + building a kernel should do all of this. Any 449 ports that use devstat need to be recompiled as well. 450 45119990125: 452 Linux threads options has gone away (they are now standard in 453 the FreeBSD kernel). A recompile of all libkvm using programs 454 is in order (or better yet a make world). 455 45619990122: 457 On or about this date there was a small window when the boot 458 blocks had some minor problems which seemed to force one to 459 edit /etc/fstab. This has been corrected, if you are seeing this 460 problem, please rebuild and reinstall your boot blocks. 461 46219990121: 463 Vinum has changed. The "vinum read" command has changed. For 464 updates, please see 465 466http://www.freebsd.org/cgi/getmsg.cgi?fetch=800363+0+current/freebsd-current 467 468 for details. 469 470 Matt Dillon committed a boatload of VM changes, for 471 information please see 472 473http://www.freebsd.org/cgi/getmsg.cgi?fetch=886676+0+current/freebsd-current 474 or 475http://www.freebsd.org/cgi/getmsg.cgi?fetch=827400+0+current/freebsd-current 476 477 for details. These changes will likely not impact anybody, 478 but large chagnes to the VM need at least a heads up. 479 48019990120: 481 Stable branch created. You might want to consider using this 482 branch. It is tagged with RELENG_3. 483 48419990119: 485 More work on the syscons driver has been committed. Since 486 files moved around, you will need to reconfigure your kernel, 487 and make clean; make depend before rebuilding the kernel. No 488 config file changes are needed. 489 49019990111: 491 New keyboard and video card drivers are introduced as the first 492 stage of console driver reorganization. You are required to 493 update the kernel configuration file and rebuild the kernel. 494 kbdcontrol, vidcontrol, and screen savers also need recompilation. 495 The instruction can be found in 496 497 http://www.freebsd.org/~yokota/sc_update.txt 498 499 It has notes on splash screen too. 500 50119990106: 502 Robert Nordier was kind enough to make this page to enable people to 503 install the new bootblocks: 504 505 http://www.freebsd.org/~rnordier/boot.txt 506 507 When updating to ELF, make sure that you have updated your 508 /etc/rc files which have different ldconfig invocations for 509 elf and aout. Otherwise things like X will stop working with 510 messages about being unable to find library files. The 511 mergemaster utility in ports/sysutils/mergemaster helps to 512 keep critical files like this in sync, and its use is 513 recommended. 514 51519990104: 516 Information about ELF day (see 19981230) can be found in 517 518 http://www.freebsd.org/~peter/elfday.html 519 520 about the upcoming change, its motivations and instructions 521 for doing the upgrade. 522 52319981230: 524 You should install new bootblocks now. The ELF kernel will 525 become default soon. In addition, you'll need to upgrade 526 your userland programs to ELF before then as well. Use 527 make aout-to-elf to upgrade your userland programs (old 528 a.out programs in, for example, /usr/local/bin will 529 continue to work, even after the upgrade). See src/Makefile 530 for more details. 531 53219981224: 533 The old wcd driver has been deleted from the kernel. The 534 driver that replaces it is named acd. You'll need to change 535 this in your configuration files. 536 537 Failure to do this will result in "ATAPI CD-ROMs not 538 configured" at boot time. 539 540 The floppy tape driver (ft) has been removed from the kernel, 541 with no replacement driver. 542 54319981202: 544 New groups from 19981201 commented out of mtree, so they 545 aren't strictly needed, but still a good idea to have. 546 54719981201: 548 New user/group added: bind. From src/etc/master.passwd and 549 src/etc/group: 550 % grep <newstuff> /usr/src/etc/group 551 bind:*:53: 552 % grep <newstuff> /usr/src/etc/master.passwd 553 tty:*:4:65533::0:0:Tty Sandbox:/:/sbin/nologin 554 kmem:*:5:65533::0:0:KMem Sandbox:/:/sbin/nologin 555 bind:*:53:53::0:0:Bind Sandbox:/:/sbin/nologin 556 55719981118: 558 PAM integrated into the tree. Requires new /etc/pam.conf file 559 to silence warnings from authentication programs (login, etc). 560 See src/etc/pam.conf for a sample. 561 562COMMON ITEMS: 563 564 To build a kernel 565 ----------------- 566 Update config, genassym and go: 567 cd src/usr.bin/genassym 568 make depend all install clean 569 cd ../../usr.sbin/config 570 make depend all install clean 571 cd ../../../sys/i386/conf 572 config YOUR_KERNEL_HERE 573 cd ../../compile/YOUR_KERNEL_HERE 574 make depend && make 575 576FORMAT: 577 578This file contains a list, in reverse chronologocal order, of major 579breakages in tracking -current.
