1Updating Information for FreeBSD current users 2 3This file is maintained and copyrighted by M. Warner Losh 4<imp@village.org>. See end of file for further details. For commonly 5done items, please see the COMMON ITEMS: section later in the file. 6 7NOTE TO PEOPLE WHO THINK THAT 5.0-CURRENT IS SLOW: 8 FreeBSD 5.0-CURRENT has many debugging features turned on, in 9 both the kernel and userland. These features attempt to detect 10 incorrect use of system primitives, and encourage loud failure 11 through extra sanity checking and fail stop semantics. They 12 also substantially impact system performance. If you want to 13 do performance measurement, benchmarking, and optimization, 14 you'll want to turn them off. This includes various WITNESS- 15 related kernel options, INVARIANTS, malloc debugging flags 16 in userland, and various verbose features in the kernel. Many 17 developers choose to disable these features on build machines 18 to maximize performance. 19 20 In addition, IDE write caching is currently disabled by default 21 due to on-going concerns about disk write order and file system 22 integrity. Re-enabling write caching can substantially improve 23 performance. 24 2520020511: 26 The k5su utility installed as part of Kerberos 5 is no longer 27 installed with the set-user-ID bit set by default. Add 28 ENABLE_SUID_K5SU=yes to /etc/make.conf to have it installed 29 with the set-user-ID bit set. 30 3120020510: 32 Gcc 3.1 debugging format (cc -g) has changed from STABS to DWARF2. 33 Unfortunately our native GDB (at version 4.18) does not understand 34 the DWARF2 debugging format. Thus you must use `gcc -gstabs+' to 35 generated debugging information for our native GDB. 36 3720020510: 38 Due to the way CVS works, it may not properly update src/contrib/gcc 39 to the 3.1 sources. The easiest fix is to `rm -rf' src/contrib/gcc 40 and then do a cvs update. 41 4220020421: 43 When exec'ing set[ug]id executables, the kernel now ensures that the 44 stdio file descriptors (0..2) are open. See FreeBSD-SA-02:23.stdio. 45 4620020404: 47 New sendmail startup scripts have been installed to make it 48 easier to use alternative MTAs with FreeBSD. Setting the rc.conf 49 variable sendmail_enable to "NO" no longer prevents any sendmail 50 daemons from starting. Instead, either set sendmail_enable to 51 "NONE" or change mta_start_script to a script for starting 52 an alternative MTA. Setting mta_start_script to "" will 53 also prevent any MTA from being started at boot. 54 5520020403: 56 UCONSOLE is no longer a valid kernel option. 57 5820020315: 59 FreeBSD 5.0 DP-1 was basically branched today. 60 6120020225: 62 Warnings are now errors in the kernel. Unless you are a developer, 63 you should add -DNO_WERROR to your make line. 64 6520020217: 66 sendmail 8.12.2 has been imported. The sendmail binary is no 67 longer a set-user-ID root binary and the infrastructure to support 68 command line mail submission has changed. Be sure to run 69 mergemaster (especially for updating /etc/rc, /etc/defaults/rc.conf, 70 and /etc/mail) and read /etc/mail/README for more details. 71 72 Due to the import of sendmail 8.12.2, a new user and group are 73 required in order for sendmail to run as a set-group-ID 74 binary. A 'make installworld' will use the new user and group 75 to set the owner and group of /var/spool/clientmqueue and will 76 fail if the new user and group do not exist. The 'smmsp' user 77 and group must be merged from src/etc/group and 78 src/etc/master.passwd before using 'make installworld'. 79 'mergemaster -p' will do this. You may need to install 80 mergemaster before this will work if you are updating from a 81 very old version of current. The updating recipe has changed 82 as of this date. 83 8420020112: 85 The preferred configuration method for PAM is now /etc/pam.d/ 86 rather than /etc/pam.conf. If you have an unmodified 87 pam.conf, just delete it after your next mergemaster run. If 88 you have local modifications, you can use 89 /usr/src/etc/pam.d/convert.pl to incorporate them into your 90 /etc/pam.d. 91 92 Please see the following url for more details: 93http://www.freebsd.org/cgi/mid.cgi?db=mid&id=<xzp6667fyoa.fsf@flood.ping.uio.no> 9420011229: 95 If anyone here is already using the new rc.conf(5) variable 96 networkfs_types, please note that it has changed 97http://www.freebsd.org/cgi/mid.cgi?db=mid&id=<9744.1009655556@axl.seasidesoftware.co.za> 98 9920011220: 100 sys/i4b/driver/i4b_ispppsubr.c has been retired. This file 101 started out its life in the ISDN4BSD project as an offspring 102 from sys/net/if_spppsubr.c, which eventually got a life of its 103 own. All the accumulated features and bugfixes of the i4b 104 version have now been merged back into the base system's 105 version now. The only user-visible change resulting from this 106 is that i4b's sppp(4) interfaces are to be managed with 107 spppcontrol(8) again, since ispppcontrol(8) has been retired 108 as well. (There has never been rc file support for 109 ispppcontrol in -current, but only in -stable. That will be 110 reverted by the time the changes are MFCed.) 111 11220011215: 113 The fdc(4) driver has been updated and now automatically 114 recognizes media in `standard' formats (like 1440 KB and 115 720 KB for a 3.5" high-density drive) when accessing the 116 default device node (e. g. /dev/fd0). The old variety of 117 floppy device nodes /dev/fd*.* is no longer present by 118 default, devices can be created (in DEVFS) on demand. They 119 will need to be customized then for `odd' densities using 120 fdcontrol(8). 121 12220011209: 123 The bugs in procfs' debugging support code have been fixed, 124 and truss(1) now works again. 125 12620011207: 127 Daily security checks have been split out to use the periodic(8) 128 scripts. Some change in configuration may be necessary. Please 129 see 130http://www.freebsd.org/cgi/mid.cgi?db=mid&id=<20011207155805.R8975@blossom.cjclark.org> 131 for details. 132 13320011204: 134 sos added VCD/SVCD support to ata driver and that needs the 135 kernel and burncd to be in sync. 136 13720011203: 138 The procfs pseudo-filesystem has now been converted to use the 139 pseudofs framework. If you have 'options PROCFS' in your 140 kernel config, you'll need to add 'options PSEUDOFS' if it's 141 not there already. 142 143 This change temporarily breaks truss(1); use ktrace(1) instead 144 until the issue has been resolved. 145 14620011202: 147 A security hole in OpenSSH involving `UseLogin yes' has been 148 patched. 149 15020011126: 151 You need to remove /usr/obj/.../usr.bin/tip before rebuilding 152 after this date. You need to do this only once. 153 15420011103: 155 Most of the awk issues have been resolved. Some rough 156 edges may be left, but for the most part things should be 157 back to "normal." For CURRENT's usual definition of "normal." 158 15920011030: 160 Awk has been upgraded to the one true awk from bell labs. Expect 161 choppy waves in the upgrade process. 162 16320011030: 164 The asr driver problem has been resolved. 165 16620011027: 167 Due to changes in other parts of the system, the asr driver 168 now causes the system to panic on boot. Do not use it pending 169 correction. Comment it out of any kernel config file that you 170 try to use from this date forward. 171 17220011025: 173 When crossbuilding, use TARGET=xxx where you used to use 174 MACHINE=xxx. You don't need to set TARGET_ARCH and TARGET, 175 unless you are changing both of them. To cross build pc98 on 176 an alpha, for example, you need to set TARGET=pc98 and 177 TARGET_ARCH=i386. 178 17920011001: 180 The kernel interface that burncd depends on has changed. 181 You must recompile both the kernel and userland applications 182 at the same time. 183 18420010929: 185 When crossbuilding, please set TARGET_ARCH rather than 186 MACHINE_ARCH to indicate the target. In the future, one will 187 set TARGET_MACHINE where you set MACHINE now. At the moment, 188 setting MACHINE alone for same MACHINE_ARCH machines works 189 (eg, you can build pc98 on a i386 machine and vice versa). 190 19120010927: 192 Some weird problems result from using ACPI on some machines. 193 To disable ACPI you can add 194 hint.acpi.0.disable="1" 195 to /boot/loader.conf (or by putting set X=Y at the boot 196 loader "ok" prompt). 197 198 Alternatively, you can remove it from /boot/kernel/acpi.ko 199 or use the MODULES_OVERRIDE function in your kernel config 200 file and not list acpi in that list. 201 20220010924: 203 The buildworld has been fixed. You may need to install 204 the 4.x compatibility libraries for some old binaries 205 to work. Add COMPAT4X=true to your /etc/make.conf to 206 get them installed on every installworld, or execute the 207 following to get them installed only once: 208 cd src/lib/compat/compat4x.<arch> 209 make all install 210 You will see ``__stdoutp undefined'' until you do this. 211 21220010919: 213 There's a bug in the world build process. The cross-tools 214 are build with the NEW headers, but the OLD libc.a. This 215 leads to all kinds of problems with the new libc. A temporary 216 workaround is to add 217 CFLAGS="-O -pipe -D_OLD_STDIO" 218 before building world when upgrading from 4.x to current. This 219 can be removed afterwards. 220 221 A proper fix to the buildworld target is needed. 222 22320010918: 224 Peter has committed his new kthread nfs client/server code. 225 NFS may be unstable after this date. 226 22720010912: 228 KSE has hit the tree. Lots of things are now different in 229 the kernel. While a few problems were introduced in the 230 initial commit, most of the major ones have been found and 231 corrected. 232 23320010901: 234 In OLDCARD, CardBus bridges appear to be stable. The work 235 arounds described in the 20010604 entry are now no longer 236 necessary and will be ignored. Most insert/remove problems 237 have been rectified around this date. 238 23920010823: 240 named now runs as user bind and group bind rather than as 241 root. If named_enable is set to YES in /etc/rc.conf, ensure 242 that user bind is available in /etc/passwd (using vipw(8)) 243 and that group bind is available in /etc/group. Also make 244 sure that user or group bind has read (and not write) 245 permission for your name server configuration and that it 246 has read and write permission for your slave zone files and 247 directory. 248 249 If you wish to continue to run named as root (a less secure 250 alternative), add a line to /etc/rc.conf saying 251 252 named_flags= 253 25420010709: 255 The PAM libraries have had an API upgrade that is beyond 256 the ability of the shared library major number to handle. 257 It is manifested by PAM-using ports dumping core. The 258 solution is to rebuild those ports. 259 26020010628: 261 The kernel compile module has moved from src/sys/compile/FOO 262 to src/sys/${MACHINE}/compile/FOO. 263 26420010625: 265 The pccard modem issue from 20010613 has been corrected. 266 OLDCARD support is still a little weak in -current. slot 1 is 267 known not to work on some TI based cardbus bridges. Some 268 cardbus bridges do not properly detect insert/removal events. 269 IRQ configuration needs more safety belts. 270 27120010617: 272 Softupdates problems have been corrected. 273 27420010614: 275 Peter ripped out the linkerset support. You must, as always, 276 rerun config after you cvsup if you are using the traditional 277 kernel building methods. 278 27920010613: 280 pccard modems may not work with current after 20010604 date. Some 281 do, others result in panics. *MAKE*SURE* that you update your 282 config and /etc/rc.conf ala the 20010604 entry, or you will have 283 problems (this issue will be fixed, it just hasn't been yet). 284 28520010613: 286 SOFTUPDATES seem to be broken since the middle of May or so. Do not 287 use them in current. You can disable softupdates on all mounted 288 partitions, or remove SOFTUPDATES the kernel config file. 289 29020010612: 291 After Peter's commits to the hints code, people have been noticing 292 that certain devices are attached (or try to) twice. This is due 293 to having both static hints as well as a /boot/device.hints. To 294 work around this issue, please use only one or the other mechanism 295 until this bug is fixed. 296 297 Please note that a feature of config is that if you have config 298 file FOO and FOO.hints, it automatically adds FOO.hints to the 299 hints.c file, wheather you want it to or not. 300 30120010610: 302 Locale names have changed to match other systems better. 303 30420010604: 305 pccard support for pci cards has been committed. You must change 306 your /etc/pccard.conf irq lines. It must match the irq used by 307 pcic device. Interrupt storms may result if you fail to do this. 308 Interrupt storms look a lot like a hang. 309 310 You must also install a new pccardd, otherwise you will get an 311 interrupt storm at card reset time (just after it tells you what 312 it is). 313 314 pccardd_flags="-I" is necessary for the time being. It tells pccardd 315 not to ask the kernel if the interrupt is really free or not before 316 using it. You can either change the /etc/pccard.conf irq lines to 317 match pcic, or add "-i X" to the pccardd_flags. 318 31920010530: 320 INSTALL=install -C is being deprecated. If you want to do this, 321 use COPY=-C instead. The former method will be supported for only 322 a limited time. If you see 323 324install: warning: the -d and -C options may not be specified together 325 326 in your makeworld, then you need to migrate towards using 327 COPY=-C. 328 32920010525: 330 It appears that vm is now stable enough to use again. However, 331 there may be other problems, so caution is still urged. alpha 332 definitely is in bad shape. 333 33420010521: 335 Minor repo damange has happened. This may cause problems 336 with cvsup of ports. If you get errors, please see 337 http://www.FreeBSD.org/cgi/query-pr.cgi?pr=27495 338 at the bottom for details on a workaround. The error message 339 is 340Updater failed: Cannot delete "/usr/ports/www/jakarta-tomcat/files": Directory not empty 341 34220010520: 343 Vm and/or swapping are busted on -current. Please be patient. 344 34520010519: 346 pccard has had much reorganizational work done to it over 347 the past few days. Everything should still work, but if 348 not, please contact imp@freebsd.org. 349 35020010517: 351 ata ioctl changed. Make sure to recompile both kernel and 352 userland at the same time. 353 35420010517: 355 New ncurses imported. 356 35720010512: 358 DEVFS is now opt out, not opt in. Barring major problems, this 359 will be the only way to go starting July 1. 360 36120010504: 362 OpenSSH has been updated to 2.9. Some defaults are different, 363 including RhostsRSAAuthentication, which changes from yes to no. 364 36520010502: 366 Perl breakage in 20010501 was corrected at 14:18:33 PDT. 367 36820010501: 369 Building perl was broken at 02:25:25 PDT. 370 37120010430: 372 The bug in 20010429 was corrected at 07:35:37 PDT. It is safe to 373 go back in the water. 374 37520010429: 376 A bad bug was committed at 04:48:42 PDT. Don't use kernels after 377 this date, but before the correction date. 378 37920010423: 380 old fsck and new kernel interactions appear to have been fixed. 381 38220010411: 383 fsck and the kernel were changed to handle some optimizations 384 to directory layout. This breaks backward compatibility. 385 Update only if you understand that you must not use the old 386 fsck with the new kernel ever. 387 38820010330: 389 fsck has changed the meaning of the pass column in /etc/fstab. 390 Please see the cvs commit to fsck.8 or the fsck.8 man page for 391 details. It is unclear if changes to /etc/fstab are necessary. 392 39320010319: 394 portmap had changed name to rpcbind for maximum POLA in your 395 current world. /etc/hosts.{allow,deny} needs changes. nfs and 396 other rpc based programs that rely on portmapper will not work 397 without updates to /etc/hosts.{allow,deny} and /etc/netconfig. 398 39920010315: 400 ata subsystem changes. ATA_ENABLE_ATAPI_DMA, ATA_ENABLE_WC 401 and ATA_ENABEL_TAGS are no longer kernel options. They have 402 been replaced by tunables. See ata.4 for details. 403 40420010312: 405 The fxp driver was converted to use miibus. If you compile 406 fxp into your kernel statically, you will need to add miibus. 407 40820010312: 409 The wi device now defaults to BSS (infrastructure) mode 410 instead of ad-hoc. 411 41220010310: 413 /dev/urandom should be a symbolic link to /dev/random now. 414 Users of current not using DEVFS need to run MAKEDEV std. 415 ssh might not work if you don't. 416 41720010303: 418 The ed driver has been updated. It now allows mii attachments, 419 which means that you must include the miibus in your kernel if 420 you use the ed driver. 421 42220010220: 423 The problems with libc have been corrected. It is now mostly 424 safe to go back into the water. 425 42620010211: 427 The size of FILE was changed. This breaks upgrading. If 428 you must upgrade, be prepared for pain. It also breaks almost 429 all binaries that you've compiled on -current. You are warned 430 that before upgrading would be a good time to do a level 0 431 dump of your system. No, really, I mean it this time. 432 433 To get to the new system, you'll need to use the following 434 workaround. Hopefully this can be sorted out so that we 435 don't have to move this to the updating section. 436 437 To get around the installworld problem, do: 438 # cd /usr/src/usr.bin/sed 439 # make install 440 # cd /usr/src 441 # make installworld 442 If that doesn't work, then try: 443 # make -k installworld 444 # make installworld 445 44620010207: 447 DEVFS is now the default. If you use vinum, make sure that you 448 do not include devfs in your kernel as problems result. 449 45020010205: 451 FFS_ROOT and CD9660_ROOT have been removed or deprecated. 452 Remove them from your config. 453 45420010122: 455 ****************************** WARNING ****************************** 456 buildkernel has been changed slightly 457 ****************************** WARNING ****************************** 458 KERNCONF replaces the variable KERNEL for buildkernel. You 459 should update your scripts and make.conf accordingly. 460 46120010119: 462 config has changed to allow DEV_FOO as a replacement for NFOO. 463 This requires a new config to build correctly. 464 46520010116: 466 The kerrnel option I386_CPU is now mutually exclusive with the 467 other cpu types. If you have an i386 system, be sure that it 468 only had this line. Remove it for all other configurations. 469 47020010110: 471 Changes to the kernel require it and burncd be in sync. 472 47320010102: 474 Everyone who has hw.sndunit set to something in 475 /etc/sysctl.conf, it is now hw.snd.unit. 476 47720010101: 478 ex and vi were broken by some changes to sys/queue.h. If you 479 have a bad vi, you will see make buildworld fail with a core 480 dump while building termcap. You can work around this problem 481 by adding -k to your make buildworld. This will cause the 482 build to complete and install a new vi. Once that's done, you 483 can rebuild again without the -k to pick up anything that 484 might have been ignored by the -k option. 485 486 Others have suggested that you can just rebuild libc if your 487 vi/ex is dynamically linked, but I've not received any reports 488 of this working. 489 49020001228: 491 There have been some changes to libcrypt in -current. The 492 libscrypt/libdescrypt symlink sillyness is gone and the installed 493 libcrypt is fully functional. Be aware of this. 494 49520001218: 496 Linksys Fast Ethernet PCCARD cards supported by the ed driver 497 now require the addition of flag 0x80000 to their config line 498 in pccard.conf(5). This flag is not optional. These Linksys 499 cards will not be recognized without it. 500 50120001205: 502 Important new FreeBSD-version stuff: PAM support has been worked 503 in, partially from the "Unix" OpenSSH version. This requires 504 adding the following in pam.conf: 505 506 sshd auth sufficient pam_skey.so 507 sshd auth required pam_unix.so try_first_pass 508 sshd session required pam_permit.so 509 51020001031: 511 cvs updated to 1.11. 512 51320001020: 514 The random device needs more entropy, so you need to make sure 515 that you've run mergemaster to get a /etc/rc which will seed 516 /dev/random. If you don't and the system hangs after ldconfig, 517 then banging on the keyboard randomly until it unhangs is one 518 workaround. 519 52020001010: 521 ****************************** WARNING ****************************** 522 Sendmail has been updated. 523 ****************************** WARNING ****************************** 524 o mail.local(8) is no longer installed as a set-user-id binary. 525 o sendmail(8) is now built with STARTTLS support unless NO_OPENSSL 526 is set. 527 o The default /etc/mail/sendmail.cf disables the SMTP EXPN and VRFY 528 commands. 529 o Now using sendmail's version of vacation(1). 530 o The sendmail cf building tools (contrib/sendmail/cf) are installed 531 in /usr/share/sendmail/cf. 532 o sendmail.cw changed to local-host-names 533 534 More details can be found at 535 http://people.freebsd.org/~imp/UPDATING/sendmail-20001010 536 53720001009: 538 The ports tree's new layout is in place. Be sure to update 539 your entire ports tree, or you will have problems. 540 54120001006: 542 The perl build procedure no longer installs miniperl, nor uses 543 the installed miniperl. It is recommended that you delete 544 /usr/bin/miniperl. 545 54620001005: 547 This weekend the ports tree will be updated to a new layout. 548 It will be in an inconsistent state until noted in the UPDATING 549 file, or with asami-san's message to the relevant mailing 550 lists. With this new layout, you'll need to update the whole 551 tree for anything to work. 552 55320000928: 554 There was a change in the passwd format. Need more information. 555 55620000916: 557 /boot/kernel/kernel.ko -> /boot/kernel/kernel change has taken 558 place. Please update boot loader (not the boot blocks) at the 559 same time as your kernel. 560 56120000914: 562 The new pmtimer device is necessary for laptops. Failure to 563 include the device will cause suspended laptops losing time 564 when they resume. Include 565 device pmtimer 566 in your config file and 567 hint.pmtimer.0.at="isa" 568 to your /boot/device.hints file. 569 57020000911: 571 The random device has been turned into a (pseudo-)device, 572 rather than an option. The supplied kernel config files have 573 been updated. You will need to do something similar in your 574 own kernel config file. 575 Remove: 576 options RANDOMDEV 577 Add: 578 device random 579 If you prefer to load the loadable module, you need to do 580 nothing. 581 58220000909: 583 The random device module has been renamed from randomdev.ko to 584 random.ko. You will need to edit your /boot/loader.conf to 585 reflect this if you load this module at boot time. 586 The line should read: 587 random_load="YES" 588 58920000907: 590 The SMPNG commit has happened. It should work, but if it 591 doesn't, fallback to the PRE_SMPNG CVS tag. There are likely 592 to be a variety of minor issues. Please see 20000905 to make 593 sure you don't have model loading problems which might at 594 first blush appear related to SMP. 595 59620000906: 597 nsswitch has been imported from NetBSD. Among other things, 598 this means that /etc/host.conf is no longer used. See 599 nsswitch.conf(5) instead. Note that at boot time rc.network 600 will attempt to produce a new nsswitch.conf file for you if you 601 don't have one, and you have host.conf. 602 60320000905: 604 The ucred structure changed size. This breaks the interface 605 that mountd uses. Trying to use an older mountd with a newer 606 kernel guarantees a panic. This means that you need to use 607 kernels newer than today only with matching mountd, but you 608 needed to do that anyway with the boot loader changes. 609 61020000905: 611 The boot loader has been updated. The new default kernel is 612 now /boot/kernel/kernel.ko. The new default module location 613 is /boot/kernel. 614 615 You *MUST* upgrade your boot loader and kernel at the same time. 616 The easiest way to do this is to do the buildworld/buildkernel/ 617 installkernel/installworld dance. 618 619 Furthermore, you are urged to delete your old /modules directory 620 before booting the new kernel, since kldload will find stale 621 modules in that directory instead of finding them in the correct 622 path, /boot/kernel. The most common complaint that this cures 623 is that the linux module crashes your machine after the update. 624 625 if [ ! -d /boot/kernel.old ]; then 626 mv /modules.old /boot/kernel.old 627 chflags noschg /kernel.old 628 mv /kernel.old /boot/kernel.old/kernel.ko 629 chflags schg /boot/kernel.old/kernel.ko 630 fi 631 63220000904: 633 A new issue with the sendmail upgrade has come to light. 634 /etc/aliases has moved to /etc/mail/aliases. Mergemaster will 635 incorrectly install the default aliases in /etc/mail rather than 636 move the old one from /etc. So you'll need to manually move the 637 file, create a symbolic link, remove the old /etc/aliases.db and 638 run newaliases. For safety sake, you should stop sendmail 639 while doing this and run the upgrade when locally sourced email 640 is not likely to be generated. 641 64220000825: 643 /boot/device.hints is now required for installkernel to 644 succeed. You should copy GENERIC.hints for your architecture 645 into /boot/device.hints. If and only if you compile hints 646 into your kernel, then this file may be empty. Please note, 647 if you have an empty or missing /boot/device.hints file and 648 you neglected to compile hints into your kernel, no boot 649 messages will appear after the boot loader tries to start the 650 kernel. 651 65220000821: 653 If you do NOT have ``options RANDOMDEV'' in your kernel and 654 you DO want the random device then add randomdev_load="YES" to 655 /boot/loader.conf. 656 65720000812: 658 suidperl is now always built and installed on the system, but 659 with permissions of 511. If you have applications that use 660 this program, you are now required to add ENABLE_SUIDPERL=true 661 to /etc/make.conf. If you forget to do this, 662 chmod 4511 /usr/bin/suidperl 663 will fix this until the next build. 664 66520000812: 666 sendmail has been updated from 8.9.3 to 8.11.0. Some of the more 667 visible changes that may immediately affect your configuration 668 include: 669 - New default file locations from src/contrib/sendmail/cf/README 670 - newaliases limited to root and trusted users 671 - MSA port (587) turned on by default 672 - New queue file naming system so can't go from 8.11 -> 8.9 673 - FEATURE(`rbl') renamed to FEATURE(`dnsbl') 674 - FEATURE(`nullclient') is more full featured 675 - FEATURE(`nouucp') requires an argument: `reject' or `nospecial' 676 - mail.local FreeBSD-only -b option changed to -B 677 - See src/contrib/sendmail/RELEASE_NOTES for more info 678 67920000810: 680 suidperl (aka sperl) is no longer build by default. You must 681 specifically define BUILD_SUIDPERL to "true" for it to be build. 682 Furthermore, we recommend that you remove /usr/bin/sperl* and 683 /usr/bin/suidperl files from your system unless you have a 684 specific use for it. 685 68620000729: 687 Networking defaults have been tightened. Anybody upgrading 688 /etc/defaults/rc.conf needs to add the following lines to 689 /etc/rc.conf if they want to have the same setup 690 afterwards (unless the variables already are set, of course): 691 # Enable network daemons for user convenience. 692 inetd_enable="YES" 693 portmap_enable="YES" 694 sendmail_enable="YES" 695 69620000728: 697 If you have null_load="YES" in your /boot/loader.conf, you 698 will need to change that to nullfs_load="YES". 699 70020000728: 701 The "installkernel" target has changed slightly. Now even if 702 you override KERNEL e.g. 'make installkernel KERNEL=MYKERNEL' 703 it will install the MYKERNEL file (built with the buildkernel 704 target) as /kernel rather than /MYKERNEL. Those who have 705 updated their /boot/loader.conf files to point to /MYKERNEL 706 should remove that entry or perform manual rename of /kernel 707 to /MYKERNEL. 708 70920000711: 710 If you use CVSUP or CTM to get CVS trees, AND you used to get 711 the old crypto files from internat.freebsd.org AND you check 712 out files from the CVS tree with the cvs command, please read 713 http://people.freebsd.org/~imp/internat.txt 714 for details on potential problems that you might have and how 715 to get around them. 716 717 If you are merely a mirror, or don't answer yes to each of the 718 clauses above, you needn't worry. 719 72020000711: 721 /etc/security has been updated to print the inode number of 722 setuid programs that have changed. You will see a large spike 723 in the number of changed programs the first time when you run 724 mergemaster to get a new /etc/security. 725 72620000710: 727 /dev/random now has good entropy collection (from the keyboard 728 and sysmouse drivers). Please ensure that either `options 729 RANDOMDEV' is present in your kernel config file or that 730 `randomdev_load="YES"' is in your /boot/loader.conf. If you do 731 not have the /dev/random driver, OpenSSL (and consequently 732 lots of crypto tools (like SSH)) will fail with strange 733 errors. (see below, 20000624). 734 735 FreeBSD-current is safe again to run Crypto. 736 73720000709: 738 phk made the malloc default options AJ. This may slow things 739 down and uncover other latent bugs in the code. If you need to 740 run at full speed, you can disable this by doing the following: 741 ln -s aj /etc/malloc.conf 742 74320000706: 744 libftpio's version was accidentally bumped a few days ago. This 745 has been corrected. You may need to remove /usr/lib/libftpio.so.6 746 before doing your next buildworld/installworld pair. It certainly 747 won't hurt to remove it before the update procedure. It will 748 break fetch until a new one is built, but ftp can be used in the 749 interim if needed. 750 75120000705: 752 The crypto packages have changed for the cvsup. This has been done 753 in a backward compatible way, but the old packages will go away at 754 some point in the future. Look at /usr/share/examples/cvsup for 755 details. 756 75720000704: 758 With the new sys/modules/sound/drivers/*, you will need to 759 set SYSDIR until you do an installworld after July 7th. 760 76120000704: 762 rc.shutdown and rc will now call the rc.d scripts with start 763 or stop. This may cause some harmless warnings from older 764 rc.d scripts that haven't been updated. 765 76620000630: 767 The libfetch based version of fetch has gone into the tree. 768 Minor problems may result on some of the less popular sites, 769 which should be reported to des@freebsd.org. 770 77120000625: 772 From approximately this date forward, one must have the crypto 773 system installed in order to build the system and kernel. 774 While not technically strictly true, one should treat it as 775 required and grab the crypto bits. If you are grabbing CVS 776 trees, src-all and cvs-crypto should be treated as if they 777 were required. You should check with the latest collections 778 to make sure that these haven't changed. 779 78020000624: 781 Mark Murray just committed the first parts of a cleanup of 782 /dev/zero, et al. This is also cleaning up /dev/random. 783 The entropy is disconnected, so DO NOT USE VERSIONS OF FREEBSD 784 -CURRENT FROM THIS POINT to 2000710 for cryptographic services 785 until Mark can merge in the fixes to this work in progress. 786 openssh and openssl should not be used to generate keys from this 787 date to the completion of the work. 788 789 If you must operate at this reduced level of security, add ' 790 options RANDOMDEV' to your kernel or modload the randomdev 791 module. You may also need to copy a new MAKEDEV to /dev and 792 recreate the random and urandom devices. 793 79420000622: 795 The license on the softupdates is now a standard 2 clause 796 BSD license. You may need to remove your symbolic links 797 that used to be required when updating. 798 79920000621: 800 Scott Flatman <sf@aracnet.com> sent in a decent write-up on 801 the config file update procedure. 802 http://people.freebsd.org/~imp/config-upd.html 803 NOTE: LINT is gone. It has been replaced with NOTES. NOTES 804 isn't buildable. However, you can generate a LINT file. 805 80620000620: 807 Binutils 2.10 have hit the tree, or will shortly. As soon 808 as they do, the problem noted in 20000522 will be resolved and 809 that workaround will no longer be required. 810 81120000615: 812 phk removed the compatibility creation of wd devices in the 813 ad driver. If you haven't done so already, you must update 814 your fstab, etc to use the ad devices instead of the wd 815 devices. 816 817 In addition, you'll need to update your boot blocks to a 818 more modern version, if you haven't already done so. Modern 819 here means 4.0 release or newer (although older releases 820 may work). 821 82220000612: 823 Peter took an axe to config(8). Be sure that you read his mail 824 on the topic before even thinking about updating. You will 825 need to create a /boot/device.hints or add a hints directive 826 to your config file to compile them in statically. The format 827 of the config file has changed as well. Please see GENERIC or 828 NEWCARD for examples of the new format. 829 830 Indirectly, this also breaks USERCONFIG. Unless a newer entry 831 says that it has been fixed, assume that must use the hints mechanism 832 in the loader if you need to use a machine with very old ISA cards 833 in it. 834 83520000522: 836 A new set of binutils went into the tree today. Anybody 837 building a kernel after this point is advised that they need 838 to rebuild their binutils (or better yet do a 839 buildworld/installworld) before building a new kernel. 840 841 Due to bugs in binutils, using malloc options (eg /etc/malloc.conf 842 or MALLOC_OPTIONS env var) J will cause ld to dump core. It 843 is recommended that you don't set this option until the problem 844 is resolved. 845 84620000513: 847 The ethernet drivers were all updated to clean up the BPF handling. 848 84920000510: 850 The problems with boot blocks on the alphas have been corrected. 851 This will require some care in updating alphas. A new libstand 852 is requires for the boot blocks to build properly. 853 85420000503: 855 Recompile all kld modules. Proper version dependency info 856 is now available. 857 85820000502: 859 Modules have been disconnected from the buildworld tree and 860 connected to the kernel building instead. 861 86220000427: 863 You may need to build gperf 864 cd /usr/src/gnu/usr.bin/gperf && make depend all install 865 when upgrading from 4.0 -> current. The build system now uses 866 an option only in -current. 867 86820000417: 869 The method that we brand ELF binaries has changed to be more 870 acceptable to the binutils maintainers. You will need to 871 rebrand your ELF binaries that aren't native. One problem 872 binary is the Linux ldconfig. After your make world, but 873 before you reboot, you'll need to issue: 874 brandelf -t Linux /compat/linux/sbin/ldconfig 875 if you have Linux compatibility enabled on your machine. 876 87720000320: 878 If you have really bad/marginal IDE drives, you may find they 879 don't work well. Use pio mode instead. The easiest way to 880 cope if you have a problem combination is to add: 881 /sbin/sysctl hw.ata.ata_dma=0 882 to the start of /etc/rc.conf. 883 88420000319: 885 The ISA and PCI compatibility shims have been connected to the 886 options COMPAT_OLDISA and COMPAT_OLDPCI. If you are using old 887 style PCI or ISA drivers (i.e. tx, voxware, etc.) you must 888 include the appropriate option in your kernel config. Drivers 889 using the shims should be updated or they won't ship with 890 5.0-RELEASE, targeted for 2001. 891 89220000318: 893 We've entered the traditional post release dumping party. 894 Large kernel changes are being committed and are in the 895 works. It is important to keep the systems' klds and kernel 896 in sync as kernel interfaces and structures are changing. 897 Before reporting kernel panics, make sure that all modules 898 that you are loading are up to date. 899 90020000315: 901 If you are upgrading from an older version of FreeBSD, you 902 need to update your boot blocks as well. 'disklabel -B ad0' 903 will do the trick. This isn't critical until you remove your 904 wd device entries in /dev, at which point your system will not 905 boot. 906 90720000315: 908 4.0 RELEASE shipped. Please see the 4.0 UPDATING file for how 909 to upgrade to 4.0 from 3.x. 910 911COMMON ITEMS: 912 913 General Notes 914 ------------- 915 Avoid using make -j when upgrading. From time to time in the 916 past there have been problems using -j with buildworld and/or 917 installworld. This is especially true when upgrading between 918 "distant" versions (eg one that cross a major release boundary 919 or several minor releases, or when several months have passed 920 on the -current branch). 921 922 Sometimes, obscure build problems are the result of environment 923 poisoning. This can happen because the make utility reads its 924 environment when searching for values for global variables. 925 To run your build attempts in an "environmental clean room", 926 prefix all make commands with 'env -i '. See the env(1) manual 927 page for more details. 928 929 To build a kernel 930 ----------------- 931 If you are updating from a prior version of FreeBSD (even one just 932 a few days old), you should follow this procedure. With a 933 /usr/obj tree with a fresh buildworld, 934 make buildkernel KERNCONF=YOUR_KERNEL_HERE 935 make installkernel KERNCONF=YOUR_KERNEL_HERE 936 937 To just build a kernel when you know that it won't mess you up 938 -------------------------------------------------------------- 939 cd src/sys/{i386,alpha}/conf 940 config KERNEL_NAME_HERE 941 cd ../../compile/KERNEL_NAME_HERE 942 make depend 943 make 944 make install 945 946 If this fails, go to the "To build a kernel" section. 947 948 To rebuild everything and install it on the current system. 949 ----------------------------------------------------------- 950 make world 951 Build a new kernel, see above. 952 953 To upgrade from 4.x-stable to current 954 ------------------------------------- 955 make buildworld 956 make buildkernel KERNCONF=YOUR_KERNEL_HERE 957 cp src/sys/${MACHINE_ARCH}/conf/GENERIC.hints /boot/device.hints [2] 958 make installkernel KERNCONF=YOUR_KERNEL_HERE 959 reboot in single user [3] 960 mergemaster -p [5] 961 make installworld 962 mergemaster [4] 963 [1] 964 <reboot> 965 966 Make sure that you've read the UPDATING file to understand the 967 tweaks to various things you need. At this point in the life 968 cycle of current, things change often and you are on your own 969 to cope. The defaults can also change, so please read ALL of 970 the UPDATING entries. 971 972 Also, if you are tracking -current, you must be subscribed to 973 freebsd-current@freebsd.org. Make sure that before you update 974 your sources that you have read and understood all the recent 975 messages there. If in doubt, please track -stable which has 976 much fewer pitfalls. 977 978 [1] If you have third party modules, such as vmware, you 979 should disable them at this point so they don't crash your 980 system on reboot. 981 982 [2] If you have legacy ISA devices, you may need to create 983 your own device.hints to reflect your unique hardware 984 configuration. 985 986 [3] From the bootblocks, boot -s, and then do 987 fsck -p 988 mount -u / 989 mount -a 990 cd /usr/src 991 adjkerntz -i # if CMOS is wall time 992 Also, when doing a major release upgrade, it is required that 993 you boot into single user mode to do the installworld. 994 995 [4] Note: This step is non-optional. Failure to do this step 996 can result in a significant reduction in the functionality of the 997 system. Attempting to do it by hand is not recommended and those 998 that pursue this avenue should read this file carefully, as well 999 as the archives of freebsd-current and freebsd-hackers mailing lists 1000 for potential gotchas. 1001 1002 [5] Usually this step is a noop. However, from time to time 1003 you may need to do this if you get unknown user in the following 1004 step. It never hurts to do it all the time. You may need to 1005 install a new mergemaster (cd src/usr.sbin/mergemaster && make 1006 install) after the buildworld before this step if you last updated 1007 from current before 20020224 or from -stable before 20020408. 1008 1009FORMAT: 1010 1011This file contains a list, in reverse chronological order, of major 1012breakages in tracking -current. Not all things will be listed here, 1013and it only starts on March 15, 2000. Updating files can found in 1014previous releases if your system is older than this. 1015 1016Copyright information: 1017 1018Copyright 1998, 2002 M. Warner Losh.
