UPDATING revision 89849
1Updating Information for FreeBSD current users 2 3This file is maintained and copyrighted by M. Warner Losh 4<imp@village.org>. Please send new entries directly to him. See end 5of file for further details. For commonly done items, please see the 6COMMON ITEMS: section later in the file. 7 820020112: 9 The preferred configuration method for PAM is now /etc/pam.d/ 10 rather than /etc/pam.conf. If you have an unmodified 11 pam.conf, just delete it after your next mergemaster run. If 12 you have local modifications, you can use 13 /usr/src/etc/pam.d/convert.pl to incorporate them into your 14 /etc/pam.d. 15 16 Please see the following url for more details: 17http://www.freebsd.org/cgi/mid.cgi?db=mid&id=<xzp6667fyoa.fsf@flood.ping.uio.no> 18 1920011229: 20 If anyone here is already using the new rc.conf(5) variable 21 networkfs_types, please note that it has changed 22http://www.freebsd.org/cgi/mid.cgi?db=mid&id=<9744.1009655556@axl.seasidesoftware.co.za> 23 2420011220: 25 sys/i4b/driver/i4b_ispppsubr.c has been retired. This file 26 started out its life in the ISDN4BSD project as an offspring 27 from sys/net/if_spppsubr.c, which eventually got a life of its 28 own. All the accumulated features and bugfixes of the i4b 29 version have now been merged back into the base system's 30 version now. The only user-visible change resulting from this 31 is that i4b's sppp(4) interfaces are to be managed with 32 spppcontrol(8) again, since ispppcontrol(8) has been retired 33 as well. (There has never been rc file support for 34 ispppcontrol in -current, but only in -stable. That will be 35 reverted by the time the changes are MFCed.) 36 3720011215: 38 The fdc(4) driver has been updated and now automatically 39 recognizes media in `standard' formats (like 1440 KB and 40 720 KB for a 3.5" high-density drive) when accessing the 41 default device node (e. g. /dev/fd0). The old variety of 42 floppy device nodes /dev/fd*.* is no longer present by 43 default, devices can be created (in DEVFS) on demand. They 44 will need to be customized then for `odd' densities using 45 fdcontrol(8). 46 4720011209: 48 The bugs in procfs' debugging support code have been fixed, 49 and truss(1) now works again. 50 5120011207: 52 Daily security checks have been split out to use the periodic(8) 53 scripts. Some change in configuration may be necessary. Please 54 see 55http://www.freebsd.org/cgi/mid.cgi?db=mid&id=<20011207155805.R8975@blossom.cjclark.org> 56 for details. 57 5820011204: 59 sos added VCD/SVCD support to ata driver and that needs the 60 kernel and burncd to be in sync. 61 6220011203: 63 The procfs pseudo-filesystem has now been converted to use the 64 pseudofs framework. If you have 'options PROCFS' in your 65 kernel config, you'll need to add 'options PSEUDOFS' if it's 66 not there already. 67 68 This change temporarily breaks truss(1); use ktrace(1) instead 69 until the issue has been resolved. 70 7120011202: 72 A security hole in OpenSSH involving `UseLogin yes' has been 73 patched. 74 7520011126: 76 You need to remove /usr/obj/.../usr.bin/tip before rebuilding 77 after this date. You need to do this only once. 78 7920011103: 80 Most of the awk issues have been resolved. Some rough 81 edges may be left, but for the most part things should be 82 back to "normal." For CURRENT's usual definition of "normal." 83 8420011030: 85 Awk has been upgraded to the one true awk from bell labs. Expect 86 choppy waves in the upgrade process. 87 8820011030: 89 The asr driver problem has been resolved. 90 9120011027: 92 Due to changes in other parts of the system, the asr driver 93 now causes the system to panic on boot. Do not use it pending 94 correction. Comment it out of any kernel config file that you 95 try to use from this date forward. 96 9720011025: 98 When crossbuilding, use TARGET=xxx where you used to use 99 MACHINE=xxx. You don't need to set TARGET_ARCH and TARGET, 100 unless you are changing both of them. To cross build pc98 on 101 an alpha, for example, you need to set TARGET=pc98 and 102 TARGET_ARCH=i386. 103 10420011001: 105 The kernel interface that burncd depends on has changed. 106 You must recompile both the kernel and userland applications 107 at the same time. 108 10920010929: 110 When crossbuilding, please set TARGET_ARCH rather than 111 MACHINE_ARCH to indicate the target. In the future, one will 112 set TARGET_MACHINE where you set MACHINE now. At the moment, 113 setting MACHINE alone for same MACHINE_ARCH machines works 114 (eg, you can build pc98 on a i386 machine and vice versa). 115 11620010927: 117 Some weird problems result from using ACPI on some machines. 118 To disable ACPI you can add 119 hint.acpi.0.disable="1" 120 to /boot/loader.conf (or by putting set X=Y at the boot 121 loader "ok" prompt). 122 123 Alternatively, you can remove it from /boot/kernel/acpi.ko 124 or use the MODULES_OVERRIDE function in your kernel config 125 file and not list acpi in that list. 126 12720010924: 128 The buildworld has been fixed. You may need to install 129 the 4.x compatibility libraries for some old binaries 130 to work. Add COMPAT4X=true to your /etc/make.conf to 131 get them installed on every installworld, or execute the 132 following to get them installed only once: 133 cd src/lib/compat/compat4x.<arch> 134 make all install 135 You will see ``__stdoutp undefined'' until you do this. 136 13720010919: 138 There's a bug in the world build process. The cross-tools 139 are build with the NEW headers, but the OLD libc.a. This 140 leads to all kinds of problems with the new libc. A temporary 141 workaround is to add 142 CFLAGS="-O -pipe -D_OLD_STDIO" 143 before building world when upgrading from 4.x to current. This 144 can be removed afterwards. 145 146 A proper fix to the buildworld target is needed. 147 14820010918: 149 Peter has committed his new kthread nfs client/server code. 150 NFS may be unstable after this date. 151 15220010912: 153 KSE has hit the tree. Lots of things are now different in 154 the kernel. While a few problems were introduced in the 155 initial commit, most of the major ones have been found and 156 corrected. 157 15820010901: 159 In OLDCARD, CardBus bridges appear to be stable. The work 160 arounds described in the 20010604 entry are now no longer 161 necessary and will be ignored. Most insert/remove problems 162 have been rectified around this date. 163 16420010823: 165 named now runs as user bind and group bind rather than as 166 root. If named_enable is set to YES in /etc/rc.conf, ensure 167 that user bind is available in /etc/passwd (using vipw(8)) 168 and that group bind is available in /etc/group. Also make 169 sure that user or group bind has read (and not write) 170 permission for your name server configuration and that it 171 has read and write permission for your slave zone files and 172 directory. 173 174 If you wish to continue to run named as root (a less secure 175 alternative), add a line to /etc/rc.conf saying 176 177 named_flags= 178 17920010709: 180 The PAM libraries have had an API upgrade that is beyond 181 the ability of the shared library major number to handle. 182 It is manifested by PAM-using ports dumping core. The 183 solution is to rebuild those ports. 184 18520010628: 186 The kernel compile module has moved from src/sys/compile/FOO 187 to src/sys/${MACHINE}/compile/FOO. 188 18920010625: 190 The pccard modem issue from 20010613 has been corrected. 191 OLDCARD support is still a little weak in -current. slot 1 is 192 known not to work on some TI based cardbus bridges. Some 193 cardbus bridges do not properly detect insert/removal events. 194 IRQ configuration needs more safety belts. 195 19620010617: 197 Softupdates problems have been corrected. 198 19920010614: 200 Peter ripped out the linkerset support. You must, as always, 201 rerun config after you cvsup if you are using the traditional 202 kernel building methods. 203 20420010613: 205 pccard modems may not work with current after 20010604 date. Some 206 do, others result in panics. *MAKE*SURE* that you update your 207 config and /etc/rc.conf ala the 20010604 entry, or you will have 208 problems (this issue will be fixed, it just hasn't been yet). 209 21020010613: 211 SOFTUPDATES seem to be broken since the middle of May or so. Do not 212 use them in current. You can disable softupdates on all mounted 213 partitions, or remove SOFTUPDATES the kernel config file. 214 21520010612: 216 After Peter's commits to the hints code, people have been noticing 217 that certain devices are attached (or try to) twice. This is due 218 to having both static hints as well as a /boot/device.hints. To 219 work around this issue, please use only one or the other mechanism 220 until this bug is fixed. 221 222 Please note that a feature of config is that if you have config 223 file FOO and FOO.hints, it automatically adds FOO.hints to the 224 hints.c file, wheather you want it to or not. 225 22620010610: 227 Locale names have changed to match other systems better. 228 22920010604: 230 pccard support for pci cards has been committed. You must change 231 your /etc/pccard.conf irq lines. It must match the irq used by 232 pcic device. Interrupt storms may result if you fail to do this. 233 Interrupt storms look a lot like a hang. 234 235 You must also install a new pccardd, otherwise you will get an 236 interrupt storm at card reset time (just after it tells you what 237 it is). 238 239 pccardd_flags="-I" is necessary for the time being. It tells pccardd 240 not to ask the kernel if the interrupt is really free or not before 241 using it. You can either change the /etc/pccard.conf irq lines to 242 match pcic, or add "-i X" to the pccardd_flags. 243 24420010530: 245 INSTALL=install -C is being deprecated. If you want to do this, 246 use COPY=-C instead. The former method will be supported for only 247 a limited time. If you see 248 249install: warning: the -d and -C options may not be specified together 250 251 in your makeworld, then you need to migrate towards using 252 COPY=-C. 253 25420010525: 255 It appears that vm is now stable enough to use again. However, 256 there may be other problems, so caution is still urged. alpha 257 definitely is in bad shape. 258 25920010521: 260 Minor repo damange has happened. This may cause problems 261 with cvsup of ports. If you get errors, please see 262 http://www.FreeBSD.org/cgi/query-pr.cgi?pr=27495 263 at the bottom for details on a workaround. The error message 264 is 265Updater failed: Cannot delete "/usr/ports/www/jakarta-tomcat/files": Directory not empty 266 26720010520: 268 Vm and/or swapping are busted on -current. Please be patient. 269 27020010519: 271 pccard has had much reorganizational work done to it over 272 the past few days. Everything should still work, but if 273 not, please contact imp@freebsd.org. 274 27520010517: 276 ata ioctl changed. Make sure to recompile both kernel and 277 userland at the same time. 278 27920010517: 280 New ncurses imported. 281 28220010512: 283 DEVFS is now opt out, not opt in. Barring major problems, this 284 will be the only way to go starting July 1. 285 28620010504: 287 OpenSSH has been updated to 2.9. Some defaults are different, 288 including RhostsRSAAuthentication, which changes from yes to no. 289 29020010502: 291 Perl breakage in 20010501 was corrected at 14:18:33 PDT. 292 29320010501: 294 Building perl was broken at 02:25:25 PDT. 295 29620010430: 297 The bug in 20010429 was corrected at 07:35:37 PDT. It is safe to 298 go back in the water. 299 30020010429: 301 A bad bug was committed at 04:48:42 PDT. Don't use kernels after 302 this date, but before the correction date. 303 30420010423: 305 old fsck and new kernel interactions appear to have been fixed. 306 30720010411: 308 fsck and the kernel were changed to handle some optimizations 309 to directory layout. This breaks backward compatibility. 310 Update only if you understand that you must not use the old 311 fsck with the new kernel ever. 312 31320010330: 314 fsck has changed the meaning of the pass column in /etc/fstab. 315 Please see the cvs commit to fsck.8 or the fsck.8 man page for 316 details. It is unclear if changes to /etc/fstab are necessary. 317 31820010319: 319 portmap had changed name to rpcbind for maximum POLA in your 320 current world. /etc/hosts.{allow,deny} needs changes. nfs and 321 other rpc based programs that rely on portmapper will not work 322 without updates to /etc/hosts.{allow,deny} and /etc/netconfig. 323 32420010315: 325 ata subsystem changes. ATA_ENABLE_ATAPI_DMA, ATA_ENABLE_WC 326 and ATA_ENABEL_TAGS are no longer kernel options. They have 327 been replaced by tunables. See ata.4 for details. 328 32920010312: 330 The fxp driver was converted to use miibus. If you compile 331 fxp into your kernel statically, you will need to add miibus. 332 33320010312: 334 The wi device now defaults to BSS (infrastructure) mode 335 instead of ad-hoc. 336 33720010310: 338 /dev/urandom should be a symbolic link to /dev/random now. 339 Users of current not using DEVFS need to run MAKEDEV std. 340 ssh might not work if you don't. 341 34220010303: 343 The ed driver has been updated. It now allows mii attachments, 344 which means that you must include the miibus in your kernel if 345 you use the ed driver. 346 34720010220: 348 The problems with libc have been corrected. It is now mostly 349 safe to go back into the water. 350 35120010211: 352 The size of FILE was changed. This breaks upgrading. If 353 you must upgrade, be prepared for pain. It also breaks almost 354 all binaries that you've compiled on -current. You are warned 355 that before upgrading would be a good time to do a level 0 356 dump of your system. No, really, I mean it this time. 357 358 To get to the new system, you'll need to use the following 359 workaround. Hopefully this can be sorted out so that we 360 don't have to move this to the updating section. 361 362 To get around the installworld problem, do: 363 # cd /usr/src/usr.bin/sed 364 # make install 365 # cd /usr/src 366 # make installworld 367 If that doesn't work, then try: 368 # make -k installworld 369 # make installworld 370 37120010207: 372 DEVFS is now the default. If you use vinum, make sure that you 373 do not include devfs in your kernel as problems result. 374 37520010205: 376 FFS_ROOT and CD9660_ROOT have been removed or deprecated. 377 Remove them from your config. 378 37920010122: 380 ****************************** WARNING ****************************** 381 buildkernel has been changed slightly 382 ****************************** WARNING ****************************** 383 KERNCONF replaces the variable KERNEL for buildkernel. You 384 should update your scripts and make.conf accordingly. 385 38620010119: 387 config has changed to allow DEV_FOO as a replacement for NFOO. 388 This requires a new config to build correctly. 389 39020010116: 391 The kerrnel option I386_CPU is now mutually exclusive with the 392 other cpu types. If you have an i386 system, be sure that it 393 only had this line. Remove it for all other configurations. 394 39520010110: 396 Changes to the kernel require it and burncd be in sync. 397 39820010102: 399 Everyone who has hw.sndunit set to something in 400 /etc/sysctl.conf, it is now hw.snd.unit. 401 40220010101: 403 ex and vi were broken by some changes to sys/queue.h. If you 404 have a bad vi, you will see make buildworld fail with a core 405 dump while building termcap. You can work around this problem 406 by adding -k to your make buildworld. This will cause the 407 build to complete and install a new vi. Once that's done, you 408 can rebuild again without the -k to pick up anything that 409 might have been ignored by the -k option. 410 411 Others have suggested that you can just rebuild libc if your 412 vi/ex is dynamically linked, but I've not received any reports 413 of this working. 414 41520001228: 416 There have been some changes to libcrypt in -current. The 417 libscrypt/libdescrypt symlink sillyness is gone and the installed 418 libcrypt is fully functional. Be aware of this. 419 42020001218: 421 Linksys Fast Ethernet PCCARD cards supported by the ed driver 422 now require the addition of flag 0x80000 to their config line 423 in pccard.conf(5). This flag is not optional. These Linksys 424 cards will not be recognized without it. 425 42620001205: 427 Important new FreeBSD-version stuff: PAM support has been worked 428 in, partially from the "Unix" OpenSSH version. This requires 429 adding the following in pam.conf: 430 431 sshd auth sufficient pam_skey.so 432 sshd auth required pam_unix.so try_first_pass 433 sshd session required pam_permit.so 434 43520001031: 436 cvs updated to 1.11. 437 43820001020: 439 The random device needs more entropy, so you need to make sure 440 that you've run mergemaster to get a /etc/rc which will seed 441 /dev/random. If you don't and the system hangs after ldconfig, 442 then banging on the keyboard randomly until it unhangs is one 443 workaround. 444 44520001010: 446 ****************************** WARNING ****************************** 447 Sendmail has been updated. 448 ****************************** WARNING ****************************** 449 o mail.local(8) is no longer installed as a set-user-id binary. 450 o sendmail(8) is now built with STARTTLS support unless NO_OPENSSL 451 is set. 452 o The default /etc/mail/sendmail.cf disables the SMTP EXPN and VRFY 453 commands. 454 o Now using sendmail's version of vacation(1). 455 o The sendmail cf building tools (contrib/sendmail/cf) are installed 456 in /usr/share/sendmail/cf. 457 o sendmail.cw changed to local-host-names 458 459 More details can be found at 460 http://people.freebsd.org/~imp/UPDATING/sendmail-20001010 461 46220001009: 463 The ports tree's new layout is in place. Be sure to update 464 your entire ports tree, or you will have problems. 465 46620001006: 467 The perl build procedure no longer installs miniperl, nor uses 468 the installed miniperl. It is recommended that you delete 469 /usr/bin/miniperl. 470 47120001005: 472 This weekend the ports tree will be updated to a new layout. 473 It will be in an inconsistent state until noted in the UPDATING 474 file, or with asami-san's message to the relevant mailing 475 lists. With this new layout, you'll need to update the whole 476 tree for anything to work. 477 47820000928: 479 There was a change in the passwd format. Need more information. 480 48120000916: 482 /boot/kernel/kernel.ko -> /boot/kernel/kernel change has taken 483 place. Please update boot loader (not the boot blocks) at the 484 same time as your kernel. 485 48620000914: 487 The new pmtimer device is necessary for laptops. Failure to 488 include the device will cause suspended laptops losing time 489 when they resume. Include 490 device pmtimer 491 in your config file and 492 hint.pmtimer.0.at="isa" 493 to your /boot/device.hints file. 494 49520000911: 496 The random device has been turned into a (pseudo-)device, 497 rather than an option. The supplied kernel config files have 498 been updated. You will need to do something similar in your 499 own kernel config file. 500 Remove: 501 options RANDOMDEV 502 Add: 503 device random 504 If you prefer to load the loadable module, you need to do 505 nothing. 506 50720000909: 508 The random device module has been renamed from randomdev.ko to 509 random.ko. You will need to edit your /boot/loader.conf to 510 reflect this if you load this module at boot time. 511 The line should read: 512 random_load="YES" 513 51420000907: 515 The SMPNG commit has happened. It should work, but if it 516 doesn't, fallback to the PRE_SMPNG CVS tag. There are likely 517 to be a variety of minor issues. Please see 20000905 to make 518 sure you don't have model loading problems which might at 519 first blush appear related to SMP. 520 52120000906: 522 nsswitch has been imported from NetBSD. Among other things, 523 this means that /etc/host.conf is no longer used. See 524 nsswitch.conf(5) instead. Note that at boot time rc.network 525 will attempt to produce a new nsswitch.conf file for you if you 526 don't have one, and you have host.conf. 527 52820000905: 529 The ucred structure changed size. This breaks the interface 530 that mountd uses. Trying to use an older mountd with a newer 531 kernel guarantees a panic. This means that you need to use 532 kernels newer than today only with matching mountd, but you 533 needed to do that anyway with the boot loader changes. 534 53520000905: 536 The boot loader has been updated. The new default kernel is 537 now /boot/kernel/kernel.ko. The new default module location 538 is /boot/kernel. 539 540 You *MUST* upgrade your boot loader and kernel at the same time. 541 The easiest way to do this is to do the buildworld/buildkernel/ 542 installkernel/installworld dance. 543 544 Furthermore, you are urged to delete your old /modules directory 545 before booting the new kernel, since kldload will find stale 546 modules in that directory instead of finding them in the correct 547 path, /boot/kernel. The most common complaint that this cures 548 is that the linux module crashes your machine after the update. 549 550 if [ ! -d /boot/kernel.old ]; then 551 mv /modules.old /boot/kernel.old 552 chflags noschg /kernel.old 553 mv /kernel.old /boot/kernel.old/kernel.ko 554 chflags schg /boot/kernel.old/kernel.ko 555 fi 556 55720000904: 558 A new issue with the sendmail upgrade has come to light. 559 /etc/aliases has moved to /etc/mail/aliases. Mergemaster will 560 incorrectly install the default aliases in /etc/mail rather than 561 move the old one from /etc. So you'll need to manually move the 562 file, create a symbolic link, remove the old /etc/aliases.db and 563 run newaliases. For safety sake, you should stop sendmail 564 while doing this and run the upgrade when locally sourced email 565 is not likely to be generated. 566 56720000825: 568 /boot/device.hints is now required for installkernel to 569 succeed. You should copy GENERIC.hints for your architecture 570 into /boot/device.hints. If and only if you compile hints 571 into your kernel, then this file may be empty. Please note, 572 if you have an empty or missing /boot/device.hints file and 573 you neglected to compile hints into your kernel, no boot 574 messages will appear after the boot loader tries to start the 575 kernel. 576 57720000821: 578 If you do NOT have ``options RANDOMDEV'' in your kernel and 579 you DO want the random device then add randomdev_load="YES" to 580 /boot/loader.conf. 581 58220000812: 583 suidperl is now always built and installed on the system, but 584 with permissions of 511. If you have applications that use 585 this program, you are now required to add ENABLE_SUIDPERL=true 586 to /etc/make.conf. If you forget to do this, 587 chmod 4511 /usr/bin/suidperl 588 will fix this until the next build. 589 59020000812: 591 sendmail has been updated from 8.9.3 to 8.11.0. Some of the more 592 visible changes that may immediately affect your configuration 593 include: 594 - New default file locations from src/contrib/sendmail/cf/README 595 - newaliases limited to root and trusted users 596 - MSA port (587) turned on by default 597 - New queue file naming system so can't go from 8.11 -> 8.9 598 - FEATURE(`rbl') renamed to FEATURE(`dnsbl') 599 - FEATURE(`nullclient') is more full featured 600 - FEATURE(`nouucp') requires an argument: `reject' or `nospecial' 601 - mail.local FreeBSD-only -b option changed to -B 602 - See src/contrib/sendmail/RELEASE_NOTES for more info 603 60420000810: 605 suidperl (aka sperl) is no longer build by default. You must 606 specifically define BUILD_SUIDPERL to "true" for it to be build. 607 Furthermore, we recommend that you remove /usr/bin/sperl* and 608 /usr/bin/suidperl files from your system unless you have a 609 specific use for it. 610 61120000729: 612 Networking defaults have been tightened. Anybody upgrading 613 /etc/defaults/rc.conf needs to add the following lines to 614 /etc/rc.conf if they want to have the same setup 615 afterwards (unless the variables already are set, of course): 616 # Enable network daemons for user convenience. 617 inetd_enable="YES" 618 portmap_enable="YES" 619 sendmail_enable="YES" 620 62120000728: 622 If you have null_load="YES" in your /boot/loader.conf, you 623 will need to change that to nullfs_load="YES". 624 62520000728: 626 The "installkernel" target has changed slightly. Now even if 627 you override KERNEL e.g. 'make installkernel KERNEL=MYKERNEL' 628 it will install the MYKERNEL file (built with the buildkernel 629 target) as /kernel rather than /MYKERNEL. Those who have 630 updated their /boot/loader.conf files to point to /MYKERNEL 631 should remove that entry or perform manual rename of /kernel 632 to /MYKERNEL. 633 63420000711: 635 If you use CVSUP or CTM to get CVS trees, AND you used to get 636 the old crypto files from internat.freebsd.org AND you check 637 out files from the CVS tree with the cvs command, please read 638 http://people.freebsd.org/~imp/internat.txt 639 for details on potential problems that you might have and how 640 to get around them. 641 642 If you are merely a mirror, or don't answer yes to each of the 643 clauses above, you needn't worry. 644 64520000711: 646 /etc/security has been updated to print the inode number of 647 setuid programs that have changed. You will see a large spike 648 in the number of changed programs the first time when you run 649 mergemaster to get a new /etc/security. 650 65120000710: 652 /dev/random now has good entropy collection (from the keyboard 653 and sysmouse drivers). Please ensure that either `options 654 RANDOMDEV' is present in your kernel config file or that 655 `randomdev_load="YES"' is in your /boot/loader.conf. If you do 656 not have the /dev/random driver, OpenSSL (and consequently 657 lots of crypto tools (like SSH)) will fail with strange 658 errors. (see below, 20000624). 659 660 FreeBSD-current is safe again to run Crypto. 661 66220000709: 663 phk made the malloc default options AJ. This may slow things 664 down and uncover other latent bugs in the code. If you need to 665 run at full speed, you can disable this by doing the following: 666 ln -s aj /etc/malloc.conf 667 66820000706: 669 libftpio's version was accidentally bumped a few days ago. This 670 has been corrected. You may need to remove /usr/lib/libftpio.so.6 671 before doing your next buildworld/installworld pair. It certainly 672 won't hurt to remove it before the update procedure. It will 673 break fetch until a new one is built, but ftp can be used in the 674 interim if needed. 675 67620000705: 677 The crypto packages have changed for the cvsup. This has been done 678 in a backward compatible way, but the old packages will go away at 679 some point in the future. Look at /usr/share/examples/cvsup for 680 details. 681 68220000704: 683 With the new sys/modules/sound/drivers/*, you will need to 684 set SYSDIR until you do an installworld after July 7th. 685 68620000704: 687 rc.shutdown and rc will now call the rc.d scripts with start 688 or stop. This may cause some harmless warnings from older 689 rc.d scripts that haven't been updated. 690 69120000630: 692 The libfetch based version of fetch has gone into the tree. 693 Minor problems may result on some of the less popular sites, 694 which should be reported to des@freebsd.org. 695 69620000625: 697 From approximately this date forward, one must have the crypto 698 system installed in order to build the system and kernel. 699 While not technically strictly true, one should treat it as 700 required and grab the crypto bits. If you are grabbing CVS 701 trees, src-all and cvs-crypto should be treated as if they 702 were required. You should check with the latest collections 703 to make sure that these haven't changed. 704 70520000624: 706 Mark Murray just committed the first parts of a cleanup of 707 /dev/zero, et al. This is also cleaning up /dev/random. 708 The entropy is disconnected, so DO NOT USE VERSIONS OF FREEBSD 709 -CURRENT FROM THIS POINT to 2000710 for cryptographic services 710 until Mark can merge in the fixes to this work in progress. 711 openssh and openssl should not be used to generate keys from this 712 date to the completion of the work. 713 714 If you must operate at this reduced level of security, add ' 715 options RANDOMDEV' to your kernel or modload the randomdev 716 module. You may also need to copy a new MAKEDEV to /dev and 717 recreate the random and urandom devices. 718 71920000622: 720 The license on the softupdates is now a standard 2 clause 721 BSD license. You may need to remove your symbolic links 722 that used to be required when updating. 723 72420000621: 725 Scott Flatman <sf@aracnet.com> sent in a decent write-up on 726 the config file update procedure. 727 http://people.freebsd.org/~imp/config-upd.html 728 NOTE: LINT is gone. It has been replaced with NOTES. NOTES 729 isn't buildable. However, you can generate a LINT file. 730 73120000620: 732 Binutils 2.10 have hit the tree, or will shortly. As soon 733 as they do, the problem noted in 20000522 will be resolved and 734 that workaround will no longer be required. 735 73620000615: 737 phk removed the compatibility creation of wd devices in the 738 ad driver. If you haven't done so already, you must update 739 your fstab, etc to use the ad devices instead of the wd 740 devices. 741 742 In addition, you'll need to update your boot blocks to a 743 more modern version, if you haven't already done so. Modern 744 here means 4.0 release or newer (although older releases 745 may work). 746 74720000612: 748 Peter took an axe to config(8). Be sure that you read his mail 749 on the topic before even thinking about updating. You will 750 need to create a /boot/device.hints or add a hints directive 751 to your config file to compile them in statically. The format 752 of the config file has changed as well. Please see GENERIC or 753 NEWCARD for examples of the new format. 754 75520000522: 756 A new set of binutils went into the tree today. Anybody 757 building a kernel after this point is advised that they need 758 to rebuild their binutils (or better yet do a 759 buildworld/installworld) before building a new kernel. 760 761 Due to bugs in binutils, using malloc options (eg /etc/malloc.conf 762 or MALLOC_OPTIONS env var) J will cause ld to dump core. It 763 is recommended that you don't set this option until the problem 764 is resolved. 765 76620000513: 767 The ethernet drivers were all updated to clean up the BPF handling. 768 76920000510: 770 The problems with boot blocks on the alphas have been corrected. 771 This will require some care in updating alphas. A new libstand 772 is requires for the boot blocks to build properly. 773 77420000503: 775 Recompile all kld modules. Proper version dependency info 776 is now available. 777 77820000502: 779 Modules have been disconnected from the buildworld tree and 780 connected to the kernel building instead. 781 78220000427: 783 You may need to build gperf 784 cd /usr/src/gnu/usr.bin/gperf && make depend all install 785 when upgrading from 4.0 -> current. The build system now uses 786 an option only in -current. 787 78820000417: 789 The method that we brand ELF binaries has changed to be more 790 acceptable to the binutils maintainers. You will need to 791 rebrand your ELF binaries that aren't native. One problem 792 binary is the Linux ldconfig. After your make world, but 793 before you reboot, you'll need to issue: 794 brandelf -t Linux /compat/linux/sbin/ldconfig 795 if you have Linux compatibility enabled on your machine. 796 79720000320: 798 If you have really bad/marginal IDE drives, you may find they 799 don't work well. Use pio mode instead. The easiest way to 800 cope if you have a problem combination is to add: 801 /sbin/sysctl -w hw.atamodes=pio,pio,pio,pio 802 to the start of /etc/rc.conf. 803 80420000319: 805 The ISA and PCI compatibility shims have been connected to the 806 options COMPAT_OLDISA and COMPAT_OLDPCI. If you are using old 807 style PCI or ISA drivers (i.e. tx, voxware, etc.) you must 808 include the appropriate option in your kernel config. Drivers 809 using the shims should be updated or they won't ship with 810 5.0-RELEASE, targeted for 2001. 811 81220000318: 813 We've entered the traditional post release dumping party. 814 Large kernel changes are being committed and are in the 815 works. It is important to keep the systems' klds and kernel 816 in sync as kernel interfaces and structures are changing. 817 Before reporting kernel panics, make sure that all modules 818 that you are loading are up to date. 819 82020000315: 821 If you are upgrading from an older version of FreeBSD, you 822 need to update your boot blocks as well. 'disklabel -B ad0' 823 will do the trick. This isn't critical until you remove your 824 wd device entries in /dev, at which point your system will not 825 boot. 826 82720000315: 828 4.0 RELEASE shipped. Please see the 4.0 UPDATING file for how 829 to upgrade to 4.0 from 3.x. 830 831COMMON ITEMS: 832 833 General Notes 834 ------------- 835 Avoid using make -j when upgrading. From time to time in the 836 past there have been problems using -j with buildworld and/or 837 installworld. This is especially true when upgrading between 838 "distant" versions (eg one that cross a major release boundary 839 or several minor releases, or when several months have passed 840 on the -current branch). 841 842 Sometimes, obscure build problems are the result of environment 843 poisoning. This can happen because the make utility reads its 844 environment when searching for values for global variables. 845 To run your build attempts in an "environmental clean room", 846 prefix all make commands with 'env -i '. See the env(1) manual 847 page for more details. 848 849 To build a kernel 850 ----------------- 851 If you are updating from a prior version of FreeBSD (even one just 852 a few days old), you should follow this procedure. With a 853 /usr/obj tree with a fresh buildworld, 854 make buildkernel KERNCONF=YOUR_KERNEL_HERE 855 make installkernel KERNCONF=YOUR_KERNEL_HERE 856 857 To just build a kernel when you know that it won't mess you up 858 -------------------------------------------------------------- 859 cd src/sys/{i386,alpha}/conf 860 config KERNEL_NAME_HERE 861 cd ../../compile/KERNEL_NAME_HERE 862 make depend 863 make 864 make install 865 866 If this fails, go to the "To build a kernel" section. 867 868 To rebuild everything and install it on the current system. 869 ----------------------------------------------------------- 870 make world 871 Build a new kernel, see above. 872 873 To upgrade from 4.x-stable to current 874 ------------------------------------- 875 make buildworld 876 make buildkernel KERNCONF=YOUR_KERNEL_HERE 877 cp src/sys/${MACHINE_ARCH}/conf/GENERIC.hints /boot/device.hints [2] 878 make installkernel KERNCONF=YOUR_KERNEL_HERE 879 reboot in single user [3] 880 make installworld 881 mergemaster [4] 882 [1] 883 <reboot> 884 885 Make sure that you've read the UPDATING file to understand the 886 tweaks to various things you need. At this point in the life 887 cycle of current, things change often and you are on your own 888 to cope. The defaults can also change, so please read ALL of 889 the UPDATING entries. 890 891 Also, if you are tracking -current, you must be subscribed to 892 freebsd-current@freebsd.org. Make sure that before you update 893 your sources that you have read and understood all the recent 894 messages there. If in doubt, please track -stable which has 895 much fewer pitfalls. 896 897 [1] If you have third party modules, such as vmware, you 898 should disable them at this point so they don't crash your 899 system on reboot. 900 901 [2] If you have legacy ISA devices, you may need to create 902 your own device.hints to reflect your unique hardware 903 configuration. 904 905 [3] From the bootblocks, boot -s, and then do 906 fsck -p 907 mount -u / 908 mount -a 909 cd /usr/src 910 adjkerntz -i # if CMOS is wall time 911 912 [4] Note: This step is non-optional. Failure to do this step 913 can result in a significant reduction in the functionality of the 914 system. Attempting to do it by hand is not recommended and those 915 that pursue this avenue should read this file carefully, as well 916 as the archives of freebsd-current and freebsd-hackers mailing lists 917 for potential gotchas. 918 919FORMAT: 920 921This file contains a list, in reverse chronological order, of major 922breakages in tracking -current. Not all things will be listed here, 923and it only starts on March 15, 2000. Updating files can found in 924previous releases if your system is older than this. 925 926Please filter your entries through Warner Losh (imp@village.org) so 927that the style, formatting, etc of this file can be maintained. 928 929Copyright information: 930 931Copyright 1998, 2001 M.
