See end of file for further details. For commonly 531899Ssefdone items, please see the end of the file. Search for 'COMMON 631899SsefITEMS:' 731899Ssef 831899Ssef20010617: 931899Ssef It appears that soft updates are working again. 1031899Ssef 1131899Ssef20010614: 1231899Ssef Peter ripped out the linkerset support. You must, as always, 1331899Ssef rerun config after you cvsup if you are using the traditional 1431899Ssef kernel building methods. 1531899Ssef 1631899Ssef20010613: 1731899Ssef Two items that have been biting people: 1831899Ssef 1931899Ssef pccard modems may not work with current after 20010604 date. Some 2031899Ssef do, others result in panics. *MAKE*SURE* that you update your 2131899Ssef config ala the 20010604 entry, or you will have problems (this issue 2231899Ssef will be fixed, it just hasn't been yet). 2331899Ssef 2431899Ssef SOFTUPDATES seem to be broken since the middle of May or so. Do not 2531899Ssef use them in current. Resolution unknown. 2631899Ssef 2731899Ssef20010612: 2831899Ssef After Peter's commits to the hints code, people have been noticing 2931899Ssef that certain devices are attached (or try to) twice. This is due 3031899Ssef to having both static hints as well as a /boot/device.hints. To 3131899Ssef work around this issue, please use only one or the other mechanism 3232275Scharnier until this bug is fixed. 3332275Scharnier 3450477Speter20010610: 3532275Scharnier Locale names have changed to match other systems better. 3632275Scharnier 3731899Ssef20010604: 3831567Ssef pccard support for pci cards has been committed. You must change 3931567Ssef your /etc/pccard.conf irq lines. It must match the irq used by 4031567Ssef pcic device. Interrupt storms may result if you fail to do this. 4131567Ssef Interrupt storms look a lot like a hang. 4231567Ssef 4331567Ssef You must also install a new pccardd, otherwise you will get an 4431567Ssef interrupt storm at card reset time (just after it tells you what 4585301Sdes it is). 4685301Sdes 4785301Sdes pccardd_flags="-I" is necessary for the time being. It tells pccardd 4885301Sdes not to ask the kernel if the interrupt is really free or not before 4985301Sdes using it. You can either change the /etc/pccard.conf irq lines to 5085301Sdes match pcic, or add "-i X" to the pccardd_flags. 5185301Sdes 5285301Sdes20010530: 5332275Scharnier INSTALL=install -C is being deprecated. If you want to do this, 5432275Scharnier use COPY=-C instead. The former method will be supported for only 5532275Scharnier a limited time. If you see 5631567Ssef 5731567Ssefinstall: warning: the -d and -C options may not be specified together 5831567Ssef 5931567Ssef in your makeworld, then you need to migrate towards using 6031567Ssef COPY=-C. 61101282Smdodd 6231567Ssef20010525: 6331567Ssef It appears that vm is now stable enough to use again. However, 6431567Ssef there may be other problems, so caution is still urged. alpha 6531567Ssef definitely is in bad shape. 6631567Ssef 6731567Ssef20010521: 6831567Ssef Minor repo damanged has happened. This may cause problems 6931567Ssef with cvsup of ports. If you get errors, please see 7031567Ssef http://www.FreeBSD.org/cgi/query-pr.cgi?pr=27495 7131567Ssef at the bottom for details on a workaround. The error message 7231567Ssef is 7331567SsefUpdater failed: Cannot delete "/usr/ports/www/jakarta-tomcat/files": Directory not empty 7431567Ssef 7531567Ssef20010520: 7631567Ssef Vm and/or swapping are busted on -current. Please be patient. 7731567Ssef 7831567Ssef20010519: 7931567Ssef pccard has had much reorganizational work done to it over 8031567Ssef the past few days. Everything should still work, but if 8131567Ssef not, please contact imp@freebsd.org. 8231567Ssef 8331567Ssef20010517: 8431567Ssef ata ioctl changed. Make sure to recompile both kernel and 8531567Ssef userland at the same time. 8631567Ssef 8731567Ssef20010517: 8831567Ssef New ncurses imported. 8931567Ssef 9031567Ssef20010512: 91100357Smarkm DEVFS is now opt out, not opt in. Barring major problems, this 9231567Ssef will be the only way to go starting July 1. 9331567Ssef 9431567Ssef20010502: 9531567Ssef Perl breakage in 20010501 was corrected at 14:18:33 PDT. 9631567Ssef 9731567Ssef20010501: 9831567Ssef Building perl was broken at 02:25:25 PDT. 9931567Ssef 10031567Ssef20010430: 10131567Ssef The bug in 20010429 was corrected at 07:35:37 PDT. It is safe to 10231567Ssef go back in the water. 10331567Ssef 10431567Ssef20010429: 10531567Ssef A bad bug was committed at 04:48:42 PDT. Don't use kernels after 10631567Ssef this date, but before the correction date. 10731567Ssef 10831567Ssef20010423: 10931567Ssef old fsck and new kernel interactions appear to have been fixed. 11031567Ssef 11131567Ssef20010411: 11231567Ssef fsck and the kernel were changed to handle some optimizations 11331567Ssef to directory layout. This breaks backward compatibility. 114101282Smdodd Update only if you understand that you must not use the old 11531567Ssef fsck with the new kernel ever. 11631567Ssef 11731567Ssef20010330: 11831567Ssef fsck has changed the meaning of the pass column in /etc/fstab. 11931567Ssef Please see the cvs commit to fsck.8 or the fsck.8 man page for 12031567Ssef details. It is unclear if changes to /etc/fstab are necessary. 12131567Ssef 122101282Smdodd20010319: 123101282Smdodd portmap had changed name to rpcbind for maximum POLA in your 12431567Ssef current world. /etc/hosts.{allow,deny} needs changes. nfs and 12531567Ssef other rpc based programs that rely on portmapper will not work 126101282Smdodd without updates to /etc/hosts.{allow,deny} and /etc/netcofnig. 12731567Ssef 12831567Ssef20010315: 129101282Smdodd ata subsystem changes. ATA_ENABLE_ATAPI_DMA, ATA_ENABLE_WC 13031567Ssef and ATA_ENABEL_TAGS are no longer kernel options. They have 13131567Ssef been replaced by tunables. See ata.4 for details. 13231567Ssef 13331567Ssef20010312: 13431567Ssef The fxp driver was converted to use miibus. If you compile 13531567Ssef fxp into your kernel statically, you will need to add miibus. 13631567Ssef 13731567Ssef20010312: 13831567Ssef The wi device now defaults to BSS (infrastructure) mode 13931567Ssef instead of ad-hoc. 14031567Ssef 14131567Ssef20010310: 14231567Ssef /dev/urandom should be a symbolic link to /dev/random now. 14331567Ssef Users of current not using DEVFS need to run MAKEDEV std. 14431567Ssef ssh might not work if you don't. 14531567Ssef 14631567Ssef20010220: 14731567Ssef The problems with libc have been corrected. It is now mostly 14831567Ssef safe to go back into the water. 14931567Ssef 15031567Ssef20010211: 15131567Ssef The size of FILE was changed. This breaks upgrading. If 15231567Ssef you must upgrade, be prepared for pain. It also breaks almost 15331567Ssef all binaries that you've compiled on -current. You are warned 15431567Ssef that before upgrading would be a good time to do a level 0 15531567Ssef dump of your system. No, really, I mean it this time. 15631567Ssef 15731567Ssef To get to the new system, you'll need to use the following 15831567Ssef workaround. Hopefully this can be sorted out so that we 15931567Ssef don't have to move this to the updating section. 160101282Smdodd 16131567Ssef To get around the installworld problem, do: 16231567Ssef # cd /usr/src/usr.bin/sed 16331567Ssef # make install 16431567Ssef # cd /usr/src 16531567Ssef # make installworld 16631567Ssef If that doesn't work, then try: 16731567Ssef # make -k installworld 16831567Ssef # make installworld 16931567Ssef 17031567Ssef20010207: 17131567Ssef DEVFS is now the default. If you use vinum, make sure that you 17231567Ssef do not include devfs in your kernel as problems result. 17331567Ssef 17431567Ssef20010205: 17531567Ssef FFS_ROOT and CD9660_ROOT have been removed or deprecated. 176101282Smdodd Remove them from your config. 17731567Ssef 17831567Ssef20010122: 17931567Ssef ****************************** WARNING ****************************** 18031567Ssef buildkernel has been changed slightly 18131567Ssef ****************************** WARNING ****************************** 18231567Ssef KERNCONF replaces the variable KERNEL for buildkernel. You 18331567Ssef should update your scripts and make.conf accordingly. 18431567Ssef 18531567Ssef20010119: 18631567Ssef config has changed to allow DEV_FOO as a replacement for NFOO. 18731567Ssef This requires a new config to build correctly. 18831567Ssef 18931567Ssef20010116: 19031567Ssef The kerrnel option I386_CPU is now mutually exclusive with the 19131567Ssef other cpu types. If you have an i386 system, be sure that it 19231567Ssef only had this line. Remove it for all other configurations. 19331567Ssef 19431567Ssef20010110: 19531567Ssef Changes to the kernel require it and burncd be in sync. 19631567Ssef 19731567Ssef20010102: 19831567Ssef Everyone who has hw.sndunit set to something in 19931567Ssef /etc/sysctl.conf, it is now hw.snd.unit. 20031567Ssef 20131567Ssef20010101: 20231567Ssef ex and vi were broken by some changes to sys/queue.h. If you 20331567Ssef have a bad vi, you will see make buildworld fail with a core 20431567Ssef dump while building termcap. You can work around this problem 20531567Ssef by adding -k to your make buildworld. This will cause the 20631567Ssef build to complete and install a new vi. Once that's done, you 20731567Ssef can rebuild again without the -k to pick up anything that 20831567Ssef might have been ignored by the -k option. 20931567Ssef 21031567Ssef Others have suggested that you can just rebuild libc if your 21131567Ssef vi/ex is dynamically linked, but I've not received any reports 21231567Ssef of this working. 21331567Ssef 21431567Ssef20001228: 21531567Ssef There have been some changes to libcrypt in -current. The 21631567Ssef libscrypt/libdescrypt symlink sillyness is gone and the installed 217101282Smdodd libcrypt is fully functional. Be aware of this. 21831567Ssef 21931567Ssef20001218: 22031567Ssef Linksys Fast Ethernet PCCARD cards supported by the ed driver 22131567Ssef now require the addition of flag 0x80000 to their config line 22231567Ssef in pccard.conf(5). This flag is not optional. These Linksys 22331567Ssef cards will not be recognized without it. 22431567Ssef 22531567Ssef20001205: 22631567Ssef Important new FreeBSD-version stuff: PAM support has been worked 22731567Ssef in, partially from the "Unix" OpenSSH version. This requires 228101282Smdodd adding the following in pam.conf: 22931567Ssef 23031567Ssef sshd auth sufficient pam_skey.so 23131567Ssef sshd auth required pam_unix.so try_first_pass 23231567Ssef sshd session required pam_permit.so 23331567Ssef 23431567Ssef20001031: 23531567Ssef cvs updated to 1.11. 23631567Ssef 23731567Ssef20001020: 23831567Ssef The random device needs more entropy, so you need to make sure 23931567Ssef that you've run mergemaster to get a /etc/rc which will seed 24031567Ssef /dev/random. If you don't and the system hangs after ldconfig, 241101282Smdodd then banging on the keyboard randomly until it unhangs is one 242101282Smdodd workaround. 24331567Ssef 24431567Ssef20001010: 24531567Ssef ****************************** WARNING ****************************** 24631567Ssef Sendmail has been updated. 24731567Ssef ****************************** WARNING ****************************** 24831567Ssef o mail.local(8) is no longer installed as a set-user-id binary. 24931567Ssef o sendmail(8) is now built with STARTTLS support unless NO_OPENSSL 250101282Smdodd is set. 251101282Smdodd o The default /etc/mail/sendmail.cf disables the SMTP EXPN and VRFY 25231567Ssef commands. 25331567Ssef o Now using sendmail's version of vacation(1). 254101282Smdodd o The sendmail cf building tools (contrib/sendmail/cf) are installed 25531567Ssef in /usr/share/sendmail/cf. 25631567Ssef o sendmail.cw changed to local-host-names 257101282Smdodd 25831567Ssef More details can be found at 25931567Ssef http://people.freebsd.org/~imp/UPDATING/sendmail-20001010 26031567Ssef 261101282Smdodd20001009: 262101282Smdodd The ports tree's new layout is in place. Be sure to update 26331567Ssef your entire ports tree, or you will have problems. 264101282Smdodd 26531567Ssef20001006: 26631567Ssef The perl build procedure no longer installs miniperl, nor uses 26731567Ssef the installed miniperl. It is recommended that you delete 26831567Ssef /usr/bin/miniperl. 26931567Ssef 27031567Ssef20001005: 27131567Ssef This weekend the ports tree will be updated to a new layout. 27231567Ssef It will be in an inconsistent state until noted in the UPDATING 27331567Ssef file, or with asami-san's message to the relevant mailing 27431567Ssef lists. With this new layout, you'll need to update the whole 27531567Ssef tree for anything to work. 27631567Ssef 27737453Sbde20000928: 27831567Ssef There was a change in the passwd format. Need more information. 27931567Ssef 28031567Ssef20000916: 28131567Ssef /boot/kernel/kernel.ko -> /boot/kernel/kernel change has taken 28231567Ssef place. Please update boot loader (not the boot blocks) at the 28331567Ssef same time as your kernel. 28431567Ssef 28531567Ssef20000914: 28631567Ssef The new pmtimer device is necessary for laptops. Failure to 28731567Ssef include the device will cause suspended laptops losing time 28831567Ssef when they resume. Include 28931567Ssef device pmtimer 29031567Ssef in your config file and 29131567Ssef hint.pmtimer.0.at="isa" 29231567Ssef to your /boot/device.hints file. 29337453Sbde 29431567Ssef20000911: 29531567Ssef The random device has been turned into a (pseudo-)device, 29631567Ssef rather than an option. The supplied kernel config files have 29731567Ssef been updated. You will need to do something similar in your 29831567Ssef own kernel config file. 29931567Ssef Remove: 30031567Ssef options RANDOMDEV 30131567Ssef Add: 30231567Ssef device random 30331567Ssef If you prefer to load the loadable module, you need to do 30431567Ssef nothing. 30531567Ssef 30631567Ssef20000909: 307101282Smdodd The random device module has been renamed from randomdev.ko to 30831567Ssef random.ko. You will need to edit your /boot/loader.conf to 30931567Ssef reflect this if you load this module at boot time. 310101282Smdodd The line should read: 31131567Ssef random_load="YES" 312 31320000907: 314 The SMPNG commit has happened. It should work, but if it 315 doesn't, fallback to the PRE_SMPNG CVS tag. There are likely 316 to be a variety of minor issues. Please see 20000905 to make 317 sure you don't have model loading problems which might at 318 first blush appear related to SMP. 319 32020000906: 321 nsswitch has been imported from NetBSD. Among other things, 322 this means that /etc/host.conf is no longer used. See 323 nsswitch.conf(5) instead. Note that at boot time rc.network 324 will attempt to produce a new nsswitch.conf file for you if you 325 don't have one, and you have host.conf. 326 32720000905: 328 The ucred structure changed size. This breaks the interface 329 that mountd uses. Trying to use an older mountd with a newer 330 kernel guarantees a panic. This means that you need to use 331 kernels newer than today only with matching mountd, but you 332 needed to do that anyway with the boot loader changes. 333 33420000905: 335 The boot loader has been updated. The new default kernel is 336 now /boot/kernel/kernel.ko. The new default module location 337 is /boot/kernel. 338 339 You *MUST* upgrade your boot loader and kernel at the same time. 340 The easiest way to do this is to do the buildworld/buildkernel/ 341 installkernel/installworld dance. 342 343 Furthermore, you are urged to delete your old /modules directory 344 before booting the new kernel, since kldload will find stale 345 modules in that directory instead of finding them in the correct 346 path, /boot/kernel. The most common complaint that this cures 347 is that the linux module crashes your machine after the update. 348 349 if [ ! -d /boot/kernel.old ]; then 350 mv /modules.old /boot/kernel.old 351 chflags noschg /kernel.old 352 mv /kernel.old /boot/kernel.old/kernel.ko 353 chflags schg /boot/kernel.old/kernel.ko 354 fi 355 35620000904: 357 A new issue with the sendmail upgrade has come to light. 358 /etc/aliases has moved to /etc/mail/aliases. Mergemaster will 359 incorrectly install the default aliases in /etc/mail rather than 360 move the old one from /etc. So you'll need to manually move the 361 file, create a symbolic link, remove the old /etc/aliases.db and 362 run newaliases. For safety sake, you should stop sendmail 363 while doing this and run the upgrade when locally sourced email 364 is not likely to be generated. 365 36620000825: 367 /boot/device.hints is now required for installkernel to 368 succeed. You should copy GENERIC.hints for your architecture 369 into /boot/device.hints. If and only if you compile hints 370 into your kernel, then this file may be empty. Please note, 371 if you have an empty or missing /boot/device.hints file and 372 you neglected to compile hints into your kernel, no boot 373 messages will appear after the boot loader tries to start the 374 kernel. 375 37620000821: 377 If you do NOT have ``options RANDOMDEV'' in your kernel and 378 you DO want the random device then add randomdev_load="YES" to 379 /boot/loader.conf. 380 38120000812: 382 suidperl is now always built and installed on the system, but 383 with permissions of 511. If you have applications that use 384 this program, you are now required to add ENABLE_SUIDPERL=true 385 to /etc/make.conf. If you forget to do this, 386 chmod 4511 /usr/bin/suidperl 387 will fix this until the next build. 388 38920000812: 390 sendmail has been updated from 8.9.3 to 8.11.0. Some of the more 391 visible changes that may immediately affect your configuration 392 include: 393 - New default file locations from src/contrib/sendmail/cf/README 394 - newaliases limited to root and trusted users 395 - MSA port (587) turned on by default 396 - New queue file naming system so can't go from 8.11 -> 8.9 397 - FEATURE(`rbl') renamed to FEATURE(`dnsbl') 398 - FEATURE(`nullclient') is more full featured 399 - FEATURE(`nouucp') requires an argument: `reject' or `nospecial' 400 - mail.local FreeBSD-only -b option changed to -B 401 - See src/contrib/sendmail/RELEASE_NOTES for more info 402 40320000810: 404 suidperl (aka sperl) is no longer build by default. You must 405 specifically define BUILD_SUIDPERL to "true" for it to be build. 406 Furthermore, we recommend that you remove /usr/bin/sperl* and 407 /usr/bin/suidperl files from your system unless you have a 408 specific use for it. 409 41020000729: 411 Networking defaults have been tightened. Anybody upgrading 412 /etc/defaults/rc.conf needs to add the following lines to 413 /etc/rc.conf if they want to have the same setup 414 afterwards (unless the variables already are set, of course): 415 # Enable network daemons for user convenience. 416 inetd_enable="YES" 417 portmap_enable="YES" 418 sendmail_enable="YES" 419 42020000728: 421 If you have null_load="YES" in your /boot/loader.conf, you 422 will need to change that to nullfs_load="YES". 423 42420000728: 425 The "installkernel" target has changed slightly. Now even if 426 you override KERNEL e.g. 'make installkernel KERNEL=MYKERNEL' 427 it will install the MYKERNEL file (built with the buildkernel 428 target) as /kernel rather than /MYKERNEL. Those who have 429 updated their /boot/loader.conf files to point to /MYKERNEL 430 should remove that entry or perform manual rename of /kernel 431 to /MYKERNEL. 432 43320000711: 434 If you use CVSUP or CTM to get CVS trees, AND you used to get 435 the old crypto files from internat.freebsd.org AND you check 436 out files from the CVS tree with the cvs command, please read 437 http://people.freebsd.org/~imp/internat.txt 438 for details on potential problems that you might have and how 439 to get around them. 440 441 If you are merely a mirror, or don't answer yes to each of the 442 clauses above, you needn't worry. 443 44420000711: 445 /etc/security has been updated to print the inode number of 446 setuid programs that have changed. You will see a large spike 447 in the number of changed programs the first time when you run 448 mergemaster to get a new /etc/security. 449 45020000710: 451 /dev/random now has good entropy collection (from the keyboard 452 and sysmouse drivers). Please ensure that either `options 453 RANDOMDEV' is present in your kernel config file or that 454 `randomdev_load="YES"' is in your /boot/loader.conf. If you do 455 not have the /dev/random driver, OpenSSL (and consequently 456 lots of crypto tools (like SSH)) will fail with strange 457 errors. (see below, 20000624). 458 459 FreeBSD-current is safe again to run Crypto. 460 46120000709: 462 phk made the malloc default options AJ. This may slow things 463 down and uncover other latent bugs in the code. If you need to 464 run at full speed, you can disable this by doing the following: 465 ln -s aj /etc/malloc.conf 466 46720000706: 468 libftpio's version was accidentally bumped a few days ago. This 469 has been corrected. You may need to remove /usr/lib/libftpio.so.6 470 before doing your next buildworld/installworld pair. It certainly 471 won't hurt to remove it before the update procedure. It will 472 break fetch until a new one is built, but ftp can be used in the 473 interim if needed. 474 47520000705: 476 The crypto packages have changed for the cvsup. This has been done 477 in a backward compatible way, but the old packages will go away at 478 some point in the future. Look at /usr/share/examples/cvsup for 479 details. 480 48120000704: 482 With the new sys/modules/sound/drivers/*, you will need to 483 set SYSDIR until you do an installworld after July 7th. 484 48520000704: 486 rc.shutdown and rc will now call the rc.d scripts with start 487 or stop. This may cause some harmless warnings from older 488 rc.d scripts that haven't been updated. 489 49020000630: 491 The libfetch based version of fetch has gone into the tree. 492 Minor problems may result on some of the less popular sites, 493 which should be reported to des@freebsd.org. 494 49520000625: 496 From approximately this date forward, one must have the crypto 497 system installed in order to build the system and kernel. 498 While not technically strictly true, one should treat it as 499 required and grab the crypto bits. If you are grabbing CVS 500 trees, src-all and cvs-crypto should be treated as if they 501 were required. You should check with the latest collections 502 to make sure that these haven't changed. 503 50420000624: 505 Mark Murray just committed the first parts of a cleanup of 506 /dev/zero, et al. This is also cleaning up /dev/random. 507 The entropy is disconnected, so DO NOT USE VERSIONS OF FREEBSD 508 -CURRENT FROM THIS POINT FORWARD for cryptographic services 509 until Mark can merge in the fixes to this work in progress. 510 openssh and openssl should not be used to generate keys from this 511 date to the completion of the work. 512 513 If you must operate at this reduced level of security, add ' 514 options RANDOMDEV' to your kernel or modload the randomdev 515 module. You may also need to copy a new MAKEDEV to /dev and 516 recreate the random and urandom devices. 517 51820000622: 519 The license on the softupdates is now a standard 2 clause 520 BSD license. You may need to remove your symbolic links 521 that used to be required when updating. 522 52320000621: 524 Scott Flatman <sf@aracnet.com> sent in a decent write-up on 525 the config file update procedure. 526 http://people.freebsd.org/~imp/config-upd.html 527 NOTE: LINT is gone. It has been replaced with NOTES. NOTES 528 isn't buildable. However, you can generate a LINT file. 529 53020000620: 531 Binutils 2.10 have hit the tree, or will shortly. As soon 532 as they do, the problem noted in 20000522 will be resolved and 533 that workaround will no longer be required. 534 53520000615: 536 phk removed the compatibility creation of wd devices in the 537 ad driver. If you haven't done so already, you must update 538 your fstab, etc to use the ad devices instead of the wd 539 devices. 540 541 In addition, you'll need to update your boot blocks to a 542 more modern version, if you haven't already done so. Modern 543 here means 4.0 release or newer (although older releases 544 may work). 545 54620000612: 547 Peter took an axe to config(8). Be sure that you read his mail 548 on the topic before even thinking about updating. You will 549 need to create a /boot/device.hints or add a hints directive 550 to your config file to compile them in statically. The format 551 of the config file has changed as well. Please see GENERIC or 552 NEWCARD for examples of the new format. 553 55420000522: 555 A new set of binutils went into the tree today. Anybody 556 building a kernel after this point is advised that they need 557 to rebuild their binutils (or better yet do a 558 buildworld/installworld) before building a new kernel. 559 560 Due to bugs in binutils, using malloc options (eg /etc/malloc.conf 561 or MALLOC_OPTIONS env var) J will cause ld to dump core. It 562 is recommended that you don't set this option until the problem 563 is resolved. 564 56520000513: 566 The ethernet drivers were all updated to clean up the BPF handling. 567 56820000510: 569 The problems with boot blocks on the alphas have been corrected. 570 This will require some care in updating alphas. A new libstand 571 is requires for the boot blocks to build properly. 572 57320000503: 574 Recompile all kld modules. Proper version dependency info 575 is now available. 576 57720000502: 578 Modules have been disconnected from the buildworld tree and 579 connected to the kernel building instead. 580 58120000427: 582 You may need to build gperf 583 cd /usr/src/gnu/usr.bin/gperf && make depend all install 584 when upgrading from 4.0 -> current. The build system now uses 585 an option only in -current. 586 58720000417: 588 The method that we brand ELF binaries has changed to be more 589 acceptable to the binutils maintainers. You will need to 590 rebrand your ELF binaries that aren't native. One problem 591 binary is the Linux ldconfig. After your make world, but 592 before you reboot, you'll need to issue: 593 brandelf -t Linux /compat/linux/sbin/ldconfig 594 if you have Linux compatibility enabled on your machine. 595 59620000320: 597 If you have really bad/marginal IDE drives, you may find they 598 don't work well. Use pio mode instead. The easiest way to 599 cope if you have a problem combination is to add: 600 /sbin/sysctl -w hw.atamodes=pio,pio,pio,pio 601 to the start of /etc/rc.conf. 602 60320000319: 604 The ISA and PCI compatibility shims have been connected to the 605 options COMPAT_OLDISA and COMPAT_OLDPCI. If you are using old 606 style PCI or ISA drivers (i.e. tx, voxware, etc.) you must 607 include the appropriate option in your kernel config. Drivers 608 using the shims should be updated or they won't ship with 609 5.0-RELEASE, targeted for 2001. 610 61120000318: 612 We've entered the traditional post release dumping party. 613 Large kernel changes are being committed and are in the 614 works. It is important to keep the systems' klds and kernel 615 in sync as kernel interfaces and structures are changing. 616 Before reporting kernel panics, make sure that all modules 617 that you are loading are up to date. 618 61920000315: 620 If you are upgrading from an older version of FreeBSD, you 621 need to update your boot blocks as well. 'disklabel -B ad0' 622 will do the trick. This isn't critical until you remove your 623 wd device entries in /dev, at which point your system will not 624 boot. 625 62620000315: 627 4.0 RELEASE shipped. Please see the 4.0 UPDATING file for how 628 to upgrade to 4.0 from 3.x. 629 630COMMON ITEMS: 631 632 General Notes 633 ------------- 634 Avoid using make -j when upgrading. From time to time in the 635 past there have been problems using -j with buildworld and/or 636 installworld. This is especially true when upgrading between 637 "distant" versions (eg one that cross a major release boundary 638 or several minor releases, or when several months have passed 639 on the -current branch). 640 641 To build a kernel 642 ----------------- 643 If you are updating from a prior version of FreeBSD (even one just 644 a few days old), you should follow this procedure. With a 645 /usr/obj tree with a fresh buildworld, 646 make buildkernel KERNCONF=YOUR_KERNEL_HERE 647 make installkernel KERNCONF=YOUR_KERNEL_HERE 648 649 To just build a kernel when you know that it won't mess you up 650 -------------------------------------------------------------- 651 cd src/sys/{i386,alpha}/conf 652 config KERNEL_NAME_HERE [1] 653 cd ../../compile/KERNEL_NAME_HERE 654 make depend 655 make 656 make install 657 658 [1] If in doubt, -r might help here. 659 660 If this fails, go to the "To build a kernel" section. 661 662 To rebuild everything and install it on the current system. 663 ----------------------------------------------------------- 664 make world 665 Build a new kernel, see above. 666 667 To upgrade from 4.x-stable to current 668 ------------------------------------- 669 make buildworld 670 make buildkernel KERNCONF=YOUR_KERNEL_HERE 671 cp src/sys/${MACHINE_ARCH}/conf/GENERIC.hints /boot/device.hints [2] 672 make installkernel KERNCONF=YOUR_KERNEL_HERE 673 reboot in single user [3] 674 make installworld 675 mergemaster 676 [1] 677 <reboot> 678 679 Make sure that you've read the UPDATING file to understand the 680 tweaks to various things you need. At this point in the life 681 cycle of current, things change often and you are on your own 682 to cope. The defaults can also change, so please read ALL of 683 the UPDATING entries. 684 685 Also, if you are tracking -current, you must be subscribed to 686 freebsd-current@freebsd.org. Make sure that before you update 687 your sources that you have read and understood all the recent 688 messages there. If in doubt, please track -stable which has 689 much fewer pitfalls. 690 691 [1] If you have third party modules, such as vmware, you 692 should disable them at this point so they don't crash your 693 system on reboot. 694 695 [2] If you have legacy ISA devices, you may need to create 696 your own device.hints to reflect your unique hardware 697 configuration. 698 699 [3] From the bootblocks, boot -s, and then do 700 fsck -p 701 mount -u / 702 mount -a 703 cd /usr/src 704 adjkerntz -i # if COMS is wall time 705 706FORMAT: 707 708This file contains a list, in reverse chronological order, of major 709breakages in tracking -current. Not all things will be listed here, 710and it only starts on March 15, 2000. Updating files can found in 711previous releases if your system is older than this. 712 713Please filter your entries through Warner Losh (imp@village.org) so 714that the style, formatting, etc of this file can be maintained. 715 716$FreeBSD: head/UPDATING 78588 2001-06-22 04:50:11Z imp $ 717
