1221828SgrehanUpdating Information for FreeBSD current users 2221828Sgrehan 3221828SgrehanThis file is maintained and copyrighted by M. Warner Losh 4221828Sgrehan<imp@village.org>. See end of file for further details. For commonly 5221828Sgrehandone items, please see the COMMON ITEMS: section later in the file. 6221828Sgrehan 7221828SgrehanNOTE TO PEOPLE WHO THINK THAT 5.0-CURRENT IS SLOW: 8221828Sgrehan FreeBSD 5.0-CURRENT has many debugging features turned on, in 9221828Sgrehan both the kernel and userland. These features attempt to detect 10221828Sgrehan incorrect use of system primitives, and encourage loud failure 11221828Sgrehan through extra sanity checking and fail stop semantics. They 12221828Sgrehan also substantially impact system performance. If you want to 13221828Sgrehan do performance measurement, benchmarking, and optimization, 14221828Sgrehan you'll want to turn them off. This includes various WITNESS- 15221828Sgrehan related kernel options, INVARIANTS, malloc debugging flags 16221828Sgrehan in userland, and various verbose features in the kernel. Many 17221828Sgrehan developers choose to disable these features on build machines 18221828Sgrehan to maximize performance. 19221828Sgrehan 20221828Sgrehan In addition, IDE write caching is currently disabled by default 21221828Sgrehan due to on-going concerns about disk write order and file system 22221828Sgrehan integrity. Re-enabling write caching can substantially improve 23221828Sgrehan performance. 24221828Sgrehan 25221828Sgrehan20020729: 26221828Sgrehan COPY is being deprecated. The 20010530 change was reverted, as 27221828Sgrehan it causes far more pain than was expected, and to always compare 28221828Sgrehan before installing, please use INSTALL="install -C" again. The 29221828Sgrehan -C option is now silently ignored when used with the -d option. 30221828Sgrehan 31221828Sgrehan20020702: 32221828Sgrehan Problems with libc_r clients like KDE and GNOME have been resolved. 33221828Sgrehan There are still some minor problems with some signals but the 34266339Sjhb system is stable enough for general use again. SMP is less so than UP 35256072Sneel but each can successfully complete multiple buildworlds. 36256072Sneel Libkvm needs to be recompiled due to KSE. 37256072Sneel 38256072Sneel20020701: 39221828Sgrehan Now would be a bad time to upgrade. Something in or near the 40 KSE commit totally broke programs using libc_r like KDE and 41 GNOME. 42 4320020511: 44 The k5su utility installed as part of Kerberos 5 is no longer 45 installed with the set-user-ID bit set by default. Add 46 ENABLE_SUID_K5SU=yes to /etc/make.conf to have it installed 47 with the set-user-ID bit set. 48 4920020510: 50 Gcc 3.1 debugging format (cc -g) has changed from STABS to DWARF2. 51 Unfortunately our native GDB (at version 4.18) does not understand 52 the DWARF2 debugging format. Thus you must use `gcc -gstabs+' to 53 generated debugging information for our native GDB. 54 5520020510: 56 Due to the way CVS works, it may not properly update src/contrib/gcc 57 to the 3.1 sources. The easiest fix is to `rm -rf' src/contrib/gcc 58 and then do a cvs update. 59 6020020421: 61 When exec'ing set[ug]id executables, the kernel now ensures that the 62 stdio file descriptors (0..2) are open. See FreeBSD-SA-02:23.stdio. 63 6420020404: 65 New sendmail startup scripts have been installed to make it 66 easier to use alternative MTAs with FreeBSD. Setting the rc.conf 67 variable sendmail_enable to "NO" no longer prevents any sendmail 68 daemons from starting. Instead, either set sendmail_enable to 69 "NONE" or change mta_start_script to a script for starting 70 an alternative MTA. Setting mta_start_script to "" will 71 also prevent any MTA from being started at boot. 72 7320020403: 74 UCONSOLE is no longer a valid kernel option. 75 7620020315: 77 FreeBSD 5.0 DP-1 was basically branched today. 78 7920020225: 80 Warnings are now errors in the kernel. Unless you are a developer, 81 you should add -DNO_WERROR to your make line. 82 8320020217: 84 sendmail 8.12.2 has been imported. The sendmail binary is no 85 longer a set-user-ID root binary and the infrastructure to support 86 command line mail submission has changed. Be sure to run 87 mergemaster (especially for updating /etc/rc, /etc/defaults/rc.conf, 88 and /etc/mail) and read /etc/mail/README for more details. 89 90 Due to the import of sendmail 8.12.2, a new user and group are 91 required in order for sendmail to run as a set-group-ID 92 binary. A 'make installworld' will use the new user and group 93 to set the owner and group of /var/spool/clientmqueue and will 94 fail if the new user and group do not exist. The 'smmsp' user 95 and group must be merged from src/etc/group and 96 src/etc/master.passwd before using 'make installworld'. 97 'mergemaster -p' will do this. You may need to install 98 mergemaster before this will work if you are updating from a 99 very old version of current. The updating recipe has changed 100 as of this date. 101 10220020112: 103 The preferred configuration method for PAM is now /etc/pam.d/ 104 rather than /etc/pam.conf. If you have an unmodified 105 pam.conf, just delete it after your next mergemaster run. If 106 you have local modifications, you can use 107 /usr/src/etc/pam.d/convert.pl to incorporate them into your 108 /etc/pam.d. 109 110 Please see the following url for more details: 111http://www.freebsd.org/cgi/mid.cgi?db=mid&id=<xzp6667fyoa.fsf@flood.ping.uio.no> 11220011229: 113 If anyone here is already using the new rc.conf(5) variable 114 networkfs_types, please note that it has changed 115http://www.freebsd.org/cgi/mid.cgi?db=mid&id=<9744.1009655556@axl.seasidesoftware.co.za> 116 11720011220: 118 sys/i4b/driver/i4b_ispppsubr.c has been retired. This file 119 started out its life in the ISDN4BSD project as an offspring 120 from sys/net/if_spppsubr.c, which eventually got a life of its 121 own. All the accumulated features and bugfixes of the i4b 122 version have now been merged back into the base system's 123 version now. The only user-visible change resulting from this 124 is that i4b's sppp(4) interfaces are to be managed with 125 spppcontrol(8) again, since ispppcontrol(8) has been retired 126 as well. (There has never been rc file support for 127 ispppcontrol in -current, but only in -stable. That will be 128 reverted by the time the changes are MFCed.) 129 13020011215: 131 The fdc(4) driver has been updated and now automatically 132 recognizes media in `standard' formats (like 1440 KB and 133 720 KB for a 3.5" high-density drive) when accessing the 134 default device node (e. g. /dev/fd0). The old variety of 135 floppy device nodes /dev/fd*.* is no longer present by 136 default, devices can be created (in DEVFS) on demand. They 137 will need to be customized then for `odd' densities using 138 fdcontrol(8). 139 14020011209: 141 The bugs in procfs' debugging support code have been fixed, 142 and truss(1) now works again. 143 14420011207: 145 Daily security checks have been split out to use the periodic(8) 146 scripts. Some change in configuration may be necessary. Please 147 see 148http://www.freebsd.org/cgi/mid.cgi?db=mid&id=<20011207155805.R8975@blossom.cjclark.org> 149 for details. 150 15120011204: 152 sos added VCD/SVCD support to ata driver and that needs the 153 kernel and burncd to be in sync. 154 15520011203: 156 The procfs pseudo-filesystem has now been converted to use the 157 pseudofs framework. If you have 'options PROCFS' in your 158 kernel config, you'll need to add 'options PSEUDOFS' if it's 159 not there already. 160 161 This change temporarily breaks truss(1); use ktrace(1) instead 162 until the issue has been resolved. 163 16420011202: 165 A security hole in OpenSSH involving `UseLogin yes' has been 166 patched. 167 16820011126: 169 You need to remove /usr/obj/.../usr.bin/tip before rebuilding 170 after this date. You need to do this only once. 171 17220011103: 173 Most of the awk issues have been resolved. Some rough 174 edges may be left, but for the most part things should be 175 back to "normal." For CURRENT's usual definition of "normal." 176 17720011030: 178 Awk has been upgraded to the one true awk from bell labs. Expect 179 choppy waves in the upgrade process. 180 18120011030: 182 The asr driver problem has been resolved. 183 18420011027: 185 Due to changes in other parts of the system, the asr driver 186 now causes the system to panic on boot. Do not use it pending 187 correction. Comment it out of any kernel config file that you 188 try to use from this date forward. 189 19020011025: 191 When crossbuilding, use TARGET=xxx where you used to use 192 MACHINE=xxx. You don't need to set TARGET_ARCH and TARGET, 193 unless you are changing both of them. To cross build pc98 on 194 an alpha, for example, you need to set TARGET=pc98 and 195 TARGET_ARCH=i386. 196 19720011001: 198 The kernel interface that burncd depends on has changed. 199 You must recompile both the kernel and userland applications 200 at the same time. 201 20220010929: 203 When crossbuilding, please set TARGET_ARCH rather than 204 MACHINE_ARCH to indicate the target. In the future, one will 205 set TARGET_MACHINE where you set MACHINE now. At the moment, 206 setting MACHINE alone for same MACHINE_ARCH machines works 207 (eg, you can build pc98 on a i386 machine and vice versa). 208 20920010927: 210 Some weird problems result from using ACPI on some machines. 211 To disable ACPI you can add 212 hint.acpi.0.disable="1" 213 to /boot/loader.conf (or by putting set X=Y at the boot 214 loader "ok" prompt). 215 216 Alternatively, you can remove it from /boot/kernel/acpi.ko 217 or use the MODULES_OVERRIDE function in your kernel config 218 file and not list acpi in that list. 219 22020010924: 221 The buildworld has been fixed. You may need to install 222 the 4.x compatibility libraries for some old binaries 223 to work. Add COMPAT4X=true to your /etc/make.conf to 224 get them installed on every installworld, or execute the 225 following to get them installed only once: 226 cd src/lib/compat/compat4x.<arch> 227 make all install 228 You will see ``__stdoutp undefined'' until you do this. 229 23020010919: 231 There's a bug in the world build process. The cross-tools 232 are build with the NEW headers, but the OLD libc.a. This 233 leads to all kinds of problems with the new libc. A temporary 234 workaround is to add 235 CFLAGS="-O -pipe -D_OLD_STDIO" 236 before building world when upgrading from 4.x to current. This 237 can be removed afterwards. 238 239 A proper fix to the buildworld target is needed. 240 24120010918: 242 Peter has committed his new kthread nfs client/server code. 243 NFS may be unstable after this date. 244 24520010912: 246 KSE has hit the tree. Lots of things are now different in 247 the kernel. While a few problems were introduced in the 248 initial commit, most of the major ones have been found and 249 corrected. 250 25120010901: 252 In OLDCARD, CardBus bridges appear to be stable. The work 253 arounds described in the 20010604 entry are now no longer 254 necessary and will be ignored. Most insert/remove problems 255 have been rectified around this date. 256 25720010823: 258 named now runs as user bind and group bind rather than as 259 root. If named_enable is set to YES in /etc/rc.conf, ensure 260 that user bind is available in /etc/passwd (using vipw(8)) 261 and that group bind is available in /etc/group. Also make 262 sure that user or group bind has read (and not write) 263 permission for your name server configuration and that it 264 has read and write permission for your slave zone files and 265 directory. 266 267 If you wish to continue to run named as root (a less secure 268 alternative), add a line to /etc/rc.conf saying 269 270 named_flags= 271 27220010709: 273 The PAM libraries have had an API upgrade that is beyond 274 the ability of the shared library major number to handle. 275 It is manifested by PAM-using ports dumping core. The 276 solution is to rebuild those ports. 277 27820010628: 279 The kernel compile module has moved from src/sys/compile/FOO 280 to src/sys/${MACHINE}/compile/FOO. 281 28220010625: 283 The pccard modem issue from 20010613 has been corrected. 284 OLDCARD support is still a little weak in -current. slot 1 is 285 known not to work on some TI based cardbus bridges. Some 286 cardbus bridges do not properly detect insert/removal events. 287 IRQ configuration needs more safety belts. 288 28920010617: 290 Softupdates problems have been corrected. 291 29220010614: 293 Peter ripped out the linkerset support. You must, as always, 294 rerun config after you cvsup if you are using the traditional 295 kernel building methods. 296 29720010613: 298 pccard modems may not work with current after 20010604 date. Some 299 do, others result in panics. *MAKE*SURE* that you update your 300 config and /etc/rc.conf ala the 20010604 entry, or you will have 301 problems (this issue will be fixed, it just hasn't been yet). 302 30320010613: 304 SOFTUPDATES seem to be broken since the middle of May or so. Do not 305 use them in current. You can disable softupdates on all mounted 306 partitions, or remove SOFTUPDATES the kernel config file. 307 30820010612: 309 After Peter's commits to the hints code, people have been noticing 310 that certain devices are attached (or try to) twice. This is due 311 to having both static hints as well as a /boot/device.hints. To 312 work around this issue, please use only one or the other mechanism 313 until this bug is fixed. 314 315 Please note that a feature of config is that if you have config 316 file FOO and FOO.hints, it automatically adds FOO.hints to the 317 hints.c file, wheather you want it to or not. 318 31920010610: 320 Locale names have changed to match other systems better. 321 32220010604: 323 pccard support for pci cards has been committed. You must change 324 your /etc/pccard.conf irq lines. It must match the irq used by 325 pcic device. Interrupt storms may result if you fail to do this. 326 Interrupt storms look a lot like a hang. 327 328 You must also install a new pccardd, otherwise you will get an 329 interrupt storm at card reset time (just after it tells you what 330 it is). 331 332 pccardd_flags="-I" is necessary for the time being. It tells pccardd 333 not to ask the kernel if the interrupt is really free or not before 334 using it. You can either change the /etc/pccard.conf irq lines to 335 match pcic, or add "-i X" to the pccardd_flags. 336 33720010530: 338 INSTALL=install -C is being deprecated. If you want to do this, 339 use COPY=-C instead. The former method will be supported for only 340 a limited time. If you see 341 342install: warning: the -d and -C options may not be specified together 343 344 in your makeworld, then you need to migrate towards using 345 COPY=-C. 346 34720010525: 348 It appears that vm is now stable enough to use again. However, 349 there may be other problems, so caution is still urged. alpha 350 definitely is in bad shape. 351 35220010521: 353 Minor repo damange has happened. This may cause problems 354 with cvsup of ports. If you get errors, please see 355 http://www.FreeBSD.org/cgi/query-pr.cgi?pr=27495 356 at the bottom for details on a workaround. The error message 357 is 358Updater failed: Cannot delete "/usr/ports/www/jakarta-tomcat/files": Directory not empty 359 36020010520: 361 Vm and/or swapping are busted on -current. Please be patient. 362 36320010519: 364 pccard has had much reorganizational work done to it over 365 the past few days. Everything should still work, but if 366 not, please contact imp@freebsd.org. 367 36820010517: 369 ata ioctl changed. Make sure to recompile both kernel and 370 userland at the same time. 371 37220010517: 373 New ncurses imported. 374 37520010512: 376 DEVFS is now opt out, not opt in. Barring major problems, this 377 will be the only way to go starting July 1. 378 37920010504: 380 OpenSSH has been updated to 2.9. Some defaults are different, 381 including RhostsRSAAuthentication, which changes from yes to no. 382 38320010502: 384 Perl breakage in 20010501 was corrected at 14:18:33 PDT. 385 38620010501: 387 Building perl was broken at 02:25:25 PDT. 388 38920010430: 390 The bug in 20010429 was corrected at 07:35:37 PDT. It is safe to 391 go back in the water. 392 39320010429: 394 A bad bug was committed at 04:48:42 PDT. Don't use kernels after 395 this date, but before the correction date. 396 39720010423: 398 old fsck and new kernel interactions appear to have been fixed. 399 40020010411: 401 fsck and the kernel were changed to handle some optimizations 402 to directory layout. This breaks backward compatibility. 403 Update only if you understand that you must not use the old 404 fsck with the new kernel ever. 405 40620010330: 407 fsck has changed the meaning of the pass column in /etc/fstab. 408 Please see the cvs commit to fsck.8 or the fsck.8 man page for 409 details. It is unclear if changes to /etc/fstab are necessary. 410 41120010319: 412 portmap had changed name to rpcbind for maximum POLA in your 413 current world. /etc/hosts.{allow,deny} needs changes. nfs and 414 other rpc based programs that rely on portmapper will not work 415 without updates to /etc/hosts.{allow,deny} and /etc/netconfig. 416 41720010315: 418 ata subsystem changes. ATA_ENABLE_ATAPI_DMA, ATA_ENABLE_WC 419 and ATA_ENABEL_TAGS are no longer kernel options. They have 420 been replaced by tunables. See ata.4 for details. 421 42220010312: 423 The fxp driver was converted to use miibus. If you compile 424 fxp into your kernel statically, you will need to add miibus. 425 42620010312: 427 The wi device now defaults to BSS (infrastructure) mode 428 instead of ad-hoc. 429 43020010310: 431 /dev/urandom should be a symbolic link to /dev/random now. 432 Users of current not using DEVFS need to run MAKEDEV std. 433 ssh might not work if you don't. 434 43520010303: 436 The ed driver has been updated. It now allows mii attachments, 437 which means that you must include the miibus in your kernel if 438 you use the ed driver. 439 44020010220: 441 The problems with libc have been corrected. It is now mostly 442 safe to go back into the water. 443 44420010211: 445 The size of FILE was changed. This breaks upgrading. If 446 you must upgrade, be prepared for pain. It also breaks almost 447 all binaries that you've compiled on -current. You are warned 448 that before upgrading would be a good time to do a level 0 449 dump of your system. No, really, I mean it this time. 450 451 To get to the new system, you'll need to use the following 452 workaround. Hopefully this can be sorted out so that we 453 don't have to move this to the updating section. 454 455 To get around the installworld problem, do: 456 # cd /usr/src/usr.bin/sed 457 # make install 458 # cd /usr/src 459 # make installworld 460 If that doesn't work, then try: 461 # make -k installworld 462 # make installworld 463 46420010207: 465 DEVFS is now the default. If you use vinum, make sure that you 466 do not include devfs in your kernel as problems result. 467 46820010205: 469 FFS_ROOT and CD9660_ROOT have been removed or deprecated. 470 Remove them from your config. 471 47220010122: 473 ****************************** WARNING ****************************** 474 buildkernel has been changed slightly 475 ****************************** WARNING ****************************** 476 KERNCONF replaces the variable KERNEL for buildkernel. You 477 should update your scripts and make.conf accordingly. 478 47920010119: 480 config has changed to allow DEV_FOO as a replacement for NFOO. 481 This requires a new config to build correctly. 482 48320010116: 484 The kerrnel option I386_CPU is now mutually exclusive with the 485 other cpu types. If you have an i386 system, be sure that it 486 only had this line. Remove it for all other configurations. 487 48820010110: 489 Changes to the kernel require it and burncd be in sync. 490 49120010102: 492 Everyone who has hw.sndunit set to something in 493 /etc/sysctl.conf, it is now hw.snd.unit. 494 49520010101: 496 ex and vi were broken by some changes to sys/queue.h. If you 497 have a bad vi, you will see make buildworld fail with a core 498 dump while building termcap. You can work around this problem 499 by adding -k to your make buildworld. This will cause the 500 build to complete and install a new vi. Once that's done, you 501 can rebuild again without the -k to pick up anything that 502 might have been ignored by the -k option. 503 504 Others have suggested that you can just rebuild libc if your 505 vi/ex is dynamically linked, but I've not received any reports 506 of this working. 507 50820001228: 509 There have been some changes to libcrypt in -current. The 510 libscrypt/libdescrypt symlink sillyness is gone and the installed 511 libcrypt is fully functional. Be aware of this. 512 51320001218: 514 Linksys Fast Ethernet PCCARD cards supported by the ed driver 515 now require the addition of flag 0x80000 to their config line 516 in pccard.conf(5). This flag is not optional. These Linksys 517 cards will not be recognized without it. 518 51920001205: 520 Important new FreeBSD-version stuff: PAM support has been worked 521 in, partially from the "Unix" OpenSSH version. This requires 522 adding the following in pam.conf: 523 524 sshd auth sufficient pam_skey.so 525 sshd auth required pam_unix.so try_first_pass 526 sshd session required pam_permit.so 527 52820001031: 529 cvs updated to 1.11. 530 53120001020: 532 The random device needs more entropy, so you need to make sure 533 that you've run mergemaster to get a /etc/rc which will seed 534 /dev/random. If you don't and the system hangs after ldconfig, 535 then banging on the keyboard randomly until it unhangs is one 536 workaround. 537 53820001010: 539 ****************************** WARNING ****************************** 540 Sendmail has been updated. 541 ****************************** WARNING ****************************** 542 o mail.local(8) is no longer installed as a set-user-id binary. 543 o sendmail(8) is now built with STARTTLS support unless NO_OPENSSL 544 is set. 545 o The default /etc/mail/sendmail.cf disables the SMTP EXPN and VRFY 546 commands. 547 o Now using sendmail's version of vacation(1). 548 o The sendmail cf building tools (contrib/sendmail/cf) are installed 549 in /usr/share/sendmail/cf. 550 o sendmail.cw changed to local-host-names 551 552 More details can be found at 553 http://people.freebsd.org/~imp/UPDATING/sendmail-20001010 554 55520001009: 556 The ports tree's new layout is in place. Be sure to update 557 your entire ports tree, or you will have problems. 558 55920001006: 560 The perl build procedure no longer installs miniperl, nor uses 561 the installed miniperl. It is recommended that you delete 562 /usr/bin/miniperl. 563 56420001005: 565 This weekend the ports tree will be updated to a new layout. 566 It will be in an inconsistent state until noted in the UPDATING 567 file, or with asami-san's message to the relevant mailing 568 lists. With this new layout, you'll need to update the whole 569 tree for anything to work. 570 57120000928: 572 There was a change in the passwd format. Need more information. 573 57420000916: 575 /boot/kernel/kernel.ko -> /boot/kernel/kernel change has taken 576 place. Please update boot loader (not the boot blocks) at the 577 same time as your kernel. 578 57920000914: 580 The new pmtimer device is necessary for laptops. Failure to 581 include the device will cause suspended laptops losing time 582 when they resume. Include 583 device pmtimer 584 in your config file and 585 hint.pmtimer.0.at="isa" 586 to your /boot/device.hints file. 587 58820000911: 589 The random device has been turned into a (pseudo-)device, 590 rather than an option. The supplied kernel config files have 591 been updated. You will need to do something similar in your 592 own kernel config file. 593 Remove: 594 options RANDOMDEV 595 Add: 596 device random 597 If you prefer to load the loadable module, you need to do 598 nothing. 599 60020000909: 601 The random device module has been renamed from randomdev.ko to 602 random.ko. You will need to edit your /boot/loader.conf to 603 reflect this if you load this module at boot time. 604 The line should read: 605 random_load="YES" 606 60720000907: 608 The SMPNG commit has happened. It should work, but if it 609 doesn't, fallback to the PRE_SMPNG CVS tag. There are likely 610 to be a variety of minor issues. Please see 20000905 to make 611 sure you don't have model loading problems which might at 612 first blush appear related to SMP. 613 61420000906: 615 nsswitch has been imported from NetBSD. Among other things, 616 this means that /etc/host.conf is no longer used. See 617 nsswitch.conf(5) instead. Note that at boot time rc.network 618 will attempt to produce a new nsswitch.conf file for you if you 619 don't have one, and you have host.conf. 620 62120000905: 622 The ucred structure changed size. This breaks the interface 623 that mountd uses. Trying to use an older mountd with a newer 624 kernel guarantees a panic. This means that you need to use 625 kernels newer than today only with matching mountd, but you 626 needed to do that anyway with the boot loader changes. 627 62820000905: 629 The boot loader has been updated. The new default kernel is 630 now /boot/kernel/kernel.ko. The new default module location 631 is /boot/kernel. 632 633 You *MUST* upgrade your boot loader and kernel at the same time. 634 The easiest way to do this is to do the buildworld/buildkernel/ 635 installkernel/installworld dance. 636 637 Furthermore, you are urged to delete your old /modules directory 638 before booting the new kernel, since kldload will find stale 639 modules in that directory instead of finding them in the correct 640 path, /boot/kernel. The most common complaint that this cures 641 is that the linux module crashes your machine after the update. 642 643 if [ ! -d /boot/kernel.old ]; then 644 mv /modules.old /boot/kernel.old 645 chflags noschg /kernel.old 646 mv /kernel.old /boot/kernel.old/kernel.ko 647 chflags schg /boot/kernel.old/kernel.ko 648 fi 649 65020000904: 651 A new issue with the sendmail upgrade has come to light. 652 /etc/aliases has moved to /etc/mail/aliases. Mergemaster will 653 incorrectly install the default aliases in /etc/mail rather than 654 move the old one from /etc. So you'll need to manually move the 655 file, create a symbolic link, remove the old /etc/aliases.db and 656 run newaliases. For safety sake, you should stop sendmail 657 while doing this and run the upgrade when locally sourced email 658 is not likely to be generated. 659 66020000825: 661 /boot/device.hints is now required for installkernel to 662 succeed. You should copy GENERIC.hints for your architecture 663 into /boot/device.hints. If and only if you compile hints 664 into your kernel, then this file may be empty. Please note, 665 if you have an empty or missing /boot/device.hints file and 666 you neglected to compile hints into your kernel, no boot 667 messages will appear after the boot loader tries to start the 668 kernel. 669 67020000821: 671 If you do NOT have ``options RANDOMDEV'' in your kernel and 672 you DO want the random device then add randomdev_load="YES" to 673 /boot/loader.conf. 674 67520000812: 676 suidperl is now always built and installed on the system, but 677 with permissions of 511. If you have applications that use 678 this program, you are now required to add ENABLE_SUIDPERL=true 679 to /etc/make.conf. If you forget to do this, 680 chmod 4511 /usr/bin/suidperl 681 will fix this until the next build. 682 68320000812: 684 sendmail has been updated from 8.9.3 to 8.11.0. Some of the more 685 visible changes that may immediately affect your configuration 686 include: 687 - New default file locations from src/contrib/sendmail/cf/README 688 - newaliases limited to root and trusted users 689 - MSA port (587) turned on by default 690 - New queue file naming system so can't go from 8.11 -> 8.9 691 - FEATURE(`rbl') renamed to FEATURE(`dnsbl') 692 - FEATURE(`nullclient') is more full featured 693 - FEATURE(`nouucp') requires an argument: `reject' or `nospecial' 694 - mail.local FreeBSD-only -b option changed to -B 695 - See src/contrib/sendmail/RELEASE_NOTES for more info 696 69720000810: 698 suidperl (aka sperl) is no longer build by default. You must 699 specifically define BUILD_SUIDPERL to "true" for it to be build. 700 Furthermore, we recommend that you remove /usr/bin/sperl* and 701 /usr/bin/suidperl files from your system unless you have a 702 specific use for it. 703 70420000729: 705 Networking defaults have been tightened. Anybody upgrading 706 /etc/defaults/rc.conf needs to add the following lines to 707 /etc/rc.conf if they want to have the same setup 708 afterwards (unless the variables already are set, of course): 709 # Enable network daemons for user convenience. 710 inetd_enable="YES" 711 portmap_enable="YES" 712 sendmail_enable="YES" 713 71420000728: 715 If you have null_load="YES" in your /boot/loader.conf, you 716 will need to change that to nullfs_load="YES". 717 71820000728: 719 The "installkernel" target has changed slightly. Now even if 720 you override KERNEL e.g. 'make installkernel KERNEL=MYKERNEL' 721 it will install the MYKERNEL file (built with the buildkernel 722 target) as /kernel rather than /MYKERNEL. Those who have 723 updated their /boot/loader.conf files to point to /MYKERNEL 724 should remove that entry or perform manual rename of /kernel 725 to /MYKERNEL. 726 72720000711: 728 If you use CVSUP or CTM to get CVS trees, AND you used to get 729 the old crypto files from internat.freebsd.org AND you check 730 out files from the CVS tree with the cvs command, please read 731 http://people.freebsd.org/~imp/internat.txt 732 for details on potential problems that you might have and how 733 to get around them. 734 735 If you are merely a mirror, or don't answer yes to each of the 736 clauses above, you needn't worry. 737 73820000711: 739 /etc/security has been updated to print the inode number of 740 setuid programs that have changed. You will see a large spike 741 in the number of changed programs the first time when you run 742 mergemaster to get a new /etc/security. 743 74420000710: 745 /dev/random now has good entropy collection (from the keyboard 746 and sysmouse drivers). Please ensure that either `options 747 RANDOMDEV' is present in your kernel config file or that 748 `randomdev_load="YES"' is in your /boot/loader.conf. If you do 749 not have the /dev/random driver, OpenSSL (and consequently 750 lots of crypto tools (like SSH)) will fail with strange 751 errors. (see below, 20000624). 752 753 FreeBSD-current is safe again to run Crypto. 754 75520000709: 756 phk made the malloc default options AJ. This may slow things 757 down and uncover other latent bugs in the code. If you need to 758 run at full speed, you can disable this by doing the following: 759 ln -s aj /etc/malloc.conf 760 76120000706: 762 libftpio's version was accidentally bumped a few days ago. This 763 has been corrected. You may need to remove /usr/lib/libftpio.so.6 764 before doing your next buildworld/installworld pair. It certainly 765 won't hurt to remove it before the update procedure. It will 766 break fetch until a new one is built, but ftp can be used in the 767 interim if needed. 768 76920000705: 770 The crypto packages have changed for the cvsup. This has been done 771 in a backward compatible way, but the old packages will go away at 772 some point in the future. Look at /usr/share/examples/cvsup for 773 details. 774 77520000704: 776 With the new sys/modules/sound/drivers/*, you will need to 777 set SYSDIR until you do an installworld after July 7th. 778 77920000704: 780 rc.shutdown and rc will now call the rc.d scripts with start 781 or stop. This may cause some harmless warnings from older 782 rc.d scripts that haven't been updated. 783 78420000630: 785 The libfetch based version of fetch has gone into the tree. 786 Minor problems may result on some of the less popular sites, 787 which should be reported to des@freebsd.org. 788 78920000625: 790 From approximately this date forward, one must have the crypto 791 system installed in order to build the system and kernel. 792 While not technically strictly true, one should treat it as 793 required and grab the crypto bits. If you are grabbing CVS 794 trees, src-all and cvs-crypto should be treated as if they 795 were required. You should check with the latest collections 796 to make sure that these haven't changed. 797 79820000624: 799 Mark Murray just committed the first parts of a cleanup of 800 /dev/zero, et al. This is also cleaning up /dev/random. 801 The entropy is disconnected, so DO NOT USE VERSIONS OF FREEBSD 802 -CURRENT FROM THIS POINT to 2000710 for cryptographic services 803 until Mark can merge in the fixes to this work in progress. 804 openssh and openssl should not be used to generate keys from this 805 date to the completion of the work. 806 807 If you must operate at this reduced level of security, add ' 808 options RANDOMDEV' to your kernel or modload the randomdev 809 module. You may also need to copy a new MAKEDEV to /dev and 810 recreate the random and urandom devices. 811 81220000622: 813 The license on the softupdates is now a standard 2 clause 814 BSD license. You may need to remove your symbolic links 815 that used to be required when updating. 816 81720000621: 818 Scott Flatman <sf@aracnet.com> sent in a decent write-up on 819 the config file update procedure. 820 http://people.freebsd.org/~imp/config-upd.html 821 NOTE: LINT is gone. It has been replaced with NOTES. NOTES 822 isn't buildable. However, you can generate a LINT file. 823 82420000620: 825 Binutils 2.10 have hit the tree, or will shortly. As soon 826 as they do, the problem noted in 20000522 will be resolved and 827 that workaround will no longer be required. 828 82920000615: 830 phk removed the compatibility creation of wd devices in the 831 ad driver. If you haven't done so already, you must update 832 your fstab, etc to use the ad devices instead of the wd 833 devices. 834 835 In addition, you'll need to update your boot blocks to a 836 more modern version, if you haven't already done so. Modern 837 here means 4.0 release or newer (although older releases 838 may work). 839 84020000612: 841 Peter took an axe to config(8). Be sure that you read his mail 842 on the topic before even thinking about updating. You will 843 need to create a /boot/device.hints or add a hints directive 844 to your config file to compile them in statically. The format 845 of the config file has changed as well. Please see GENERIC or 846 NEWCARD for examples of the new format. 847 848 Indirectly, this also breaks USERCONFIG. Unless a newer entry 849 says that it has been fixed, assume that must use the hints mechanism 850 in the loader if you need to use a machine with very old ISA cards 851 in it. 852 85320000522: 854 A new set of binutils went into the tree today. Anybody 855 building a kernel after this point is advised that they need 856 to rebuild their binutils (or better yet do a 857 buildworld/installworld) before building a new kernel. 858 859 Due to bugs in binutils, using malloc options (eg /etc/malloc.conf 860 or MALLOC_OPTIONS env var) J will cause ld to dump core. It 861 is recommended that you don't set this option until the problem 862 is resolved. 863 86420000513: 865 The ethernet drivers were all updated to clean up the BPF handling. 866 86720000510: 868 The problems with boot blocks on the alphas have been corrected. 869 This will require some care in updating alphas. A new libstand 870 is requires for the boot blocks to build properly. 871 87220000503: 873 Recompile all kld modules. Proper version dependency info 874 is now available. 875 87620000502: 877 Modules have been disconnected from the buildworld tree and 878 connected to the kernel building instead. 879 88020000427: 881 You may need to build gperf 882 cd /usr/src/gnu/usr.bin/gperf && make depend all install 883 when upgrading from 4.0 -> current. The build system now uses 884 an option only in -current. 885 88620000417: 887 The method that we brand ELF binaries has changed to be more 888 acceptable to the binutils maintainers. You will need to 889 rebrand your ELF binaries that aren't native. One problem 890 binary is the Linux ldconfig. After your make world, but 891 before you reboot, you'll need to issue: 892 brandelf -t Linux /compat/linux/sbin/ldconfig 893 if you have Linux compatibility enabled on your machine. 894 89520000320: 896 If you have really bad/marginal IDE drives, you may find they 897 don't work well. Use pio mode instead. The easiest way to 898 cope if you have a problem combination is to add: 899 /sbin/sysctl hw.ata.ata_dma=0 900 to the start of /etc/rc.conf. 901 90220000319: 903 The ISA and PCI compatibility shims have been connected to the 904 options COMPAT_OLDISA and COMPAT_OLDPCI. If you are using old 905 style PCI or ISA drivers (i.e. tx, voxware, etc.) you must 906 include the appropriate option in your kernel config. Drivers 907 using the shims should be updated or they won't ship with 908 5.0-RELEASE, targeted for 2001. 909 91020000318: 911 We've entered the traditional post release dumping party. 912 Large kernel changes are being committed and are in the 913 works. It is important to keep the systems' klds and kernel 914 in sync as kernel interfaces and structures are changing. 915 Before reporting kernel panics, make sure that all modules 916 that you are loading are up to date. 917 91820000315: 919 If you are upgrading from an older version of FreeBSD, you 920 need to update your boot blocks as well. 'disklabel -B ad0' 921 will do the trick. This isn't critical until you remove your 922 wd device entries in /dev, at which point your system will not 923 boot. 924 92520000315: 926 4.0 RELEASE shipped. Please see the 4.0 UPDATING file for how 927 to upgrade to 4.0 from 3.x. 928 929COMMON ITEMS: 930 931 General Notes 932 ------------- 933 Avoid using make -j when upgrading. From time to time in the 934 past there have been problems using -j with buildworld and/or 935 installworld. This is especially true when upgrading between 936 "distant" versions (eg one that cross a major release boundary 937 or several minor releases, or when several months have passed 938 on the -current branch). 939 940 Sometimes, obscure build problems are the result of environment 941 poisoning. This can happen because the make utility reads its 942 environment when searching for values for global variables. 943 To run your build attempts in an "environmental clean room", 944 prefix all make commands with 'env -i '. See the env(1) manual 945 page for more details. 946 947 To build a kernel 948 ----------------- 949 If you are updating from a prior version of FreeBSD (even one just 950 a few days old), you should follow this procedure. With a 951 /usr/obj tree with a fresh buildworld, 952 make buildkernel KERNCONF=YOUR_KERNEL_HERE 953 make installkernel KERNCONF=YOUR_KERNEL_HERE 954 955 To just build a kernel when you know that it won't mess you up 956 -------------------------------------------------------------- 957 cd src/sys/{i386,alpha}/conf 958 config KERNEL_NAME_HERE 959 cd ../../compile/KERNEL_NAME_HERE 960 make depend 961 make 962 make install 963 964 If this fails, go to the "To build a kernel" section. 965 966 To rebuild everything and install it on the current system. 967 ----------------------------------------------------------- 968 make world 969 Build a new kernel, see above. 970 971 To upgrade from 4.x-stable to current 972 ------------------------------------- 973 make buildworld 974 make buildkernel KERNCONF=YOUR_KERNEL_HERE 975 cp src/sys/${MACHINE_ARCH}/conf/GENERIC.hints /boot/device.hints [2] 976 make installkernel KERNCONF=YOUR_KERNEL_HERE 977 reboot in single user [3] 978 mergemaster -p [5] 979 make installworld 980 mergemaster [4] 981 [1] 982 <reboot> 983 984 Make sure that you've read the UPDATING file to understand the 985 tweaks to various things you need. At this point in the life 986 cycle of current, things change often and you are on your own 987 to cope. The defaults can also change, so please read ALL of 988 the UPDATING entries. 989 990 Also, if you are tracking -current, you must be subscribed to 991 freebsd-current@freebsd.org. Make sure that before you update 992 your sources that you have read and understood all the recent 993 messages there. If in doubt, please track -stable which has 994 much fewer pitfalls. 995 996 [1] If you have third party modules, such as vmware, you 997 should disable them at this point so they don't crash your 998 system on reboot. 999 1000 [2] If you have legacy ISA devices, you may need to create 1001 your own device.hints to reflect your unique hardware 1002 configuration. 1003 1004 [3] From the bootblocks, boot -s, and then do 1005 fsck -p 1006 mount -u / 1007 mount -a 1008 cd /usr/src 1009 adjkerntz -i # if CMOS is wall time 1010 Also, when doing a major release upgrade, it is required that 1011 you boot into single user mode to do the installworld. 1012 1013 [4] Note: This step is non-optional. Failure to do this step 1014 can result in a significant reduction in the functionality of the 1015 system. Attempting to do it by hand is not recommended and those 1016 that pursue this avenue should read this file carefully, as well 1017 as the archives of freebsd-current and freebsd-hackers mailing lists 1018 for potential gotchas. 1019 1020 [5] Usually this step is a noop. However, from time to time 1021 you may need to do this if you get unknown user in the following 1022 step. It never hurts to do it all the time. You may need to 1023 install a new mergemaster (cd src/usr.sbin/mergemaster && make 1024 install) after the buildworld before this step if you last updated 1025 from current before 20020224 or from -stable before 20020408. 1026 1027FORMAT: 1028 1029This file contains a list, in reverse chronological order, of major 1030breakages in tracking -current. Not all things will be listed here, 1031and it only starts on March 15, 2000. Updating files can found in 1032previous releases if your system is older than this. 1033 1034Copyright information: 1035 1036Copyright 1998, 2002 M. Warner Losh.
