UPDATING revision 123554
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 FreeBSD 5.x IS SLOW: 8 FreeBSD 5.x 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 2020031213: 21 src/lib/libc/gen/initgroups.c:1.8 now causes logins to fail 22 if the login process is unable to successfully set the 23 process credentials to include all groups defined for the 24 user. The current kernel limit is 16 groups; administrators 25 may wish to check that users do not have over 16 groups 26 defined, or they will be unable to log in. 27 2820031203: 29 The ACPI module has been reactivated. It is no longer required 30 to compile ACPI support into kernels statically. 31 3220031112: 33 The statfs structure has been updated with 64-bit fields to 34 allow accurate reporting of multi-terabyte filesystem 35 sizes. You should build world, then build and boot the new kernel 36 BEFORE doing a `installworld' as the new kernel will know about 37 binaries using the old statfs structure, but an old kernel will 38 not know about the new system calls that support the new statfs 39 structure. 40 Note that the backwards compatibility is only present when the 41 kernel is configured with the COMPAT_FREEBSD4 option. Since 42 even /bin/sh will not run with a new kernel without said option 43 you're pretty much dead in the water without it. Make sure you 44 have COMPAT_FREEBSD4! 45 Running an old kernel after a `make world' will cause programs 46 such as `df' that do a statfs system call to fail with a bad 47 system call. Marco Wertejuk <wertejuk@mwcis.com> also reports 48 that cfsd (ports/security/cfs) needs to be recompiled after 49 these changes are installed. 50 51 ****************************DANGER******************************* 52 53 DO NOT make installworld after the buildworld w/o building and 54 installing a new kernel FIRST. You will be unable to build a 55 new kernel otherwise on a system with new binaries and an old 56 kernel. 57 5820031112: 59 Some netgraph string length constants have been changed. This 60 change requires the netgraph kernel modules and all netgraph 61 userland components to be in sync. Especially users who require 62 netgraph to boot need to make sure to have world and kernel in 63 sync before rebooting. 64 6520031111: 66 Hyperthreading logical CPU's are no longer probed by default 67 when using the MP Table. If ACPI is being used, then logical 68 CPUs will be probed if hyperthreading is enabled in the BIOS. 69 If ACPI is not being used and hyperthreading is enabled in the 70 BIOS, logical CPUs can be enabled by building a custom kernel 71 with the option MPTABLE_FORCE_HTT enabled. 72 7320031103: 74 The i386 APIC_IO kernel option has been replaced by 75 'device apic'. The ACPI module has also been temporarily 76 disabled, so ACPI must be statically compiled into your 77 kernel using 'device acpi' if you wish to use the ACPI driver. 78 7920031031: 80 The API and ABI of struct ifnet have been changed by removing 81 the if_name and if_unit members and replacing them with 82 if_xname, if_dname, and if_dunit. All network drivers and most 83 userland programs which include net/if_var.h must be updated 84 and recompiled. __FreeBSD_version has been bumped to 501113 to 85 reflect this change. 86 8720030928: 88 Changes to the cdevsw default functions have been made to remove 89 the need to specify nullopen() and nullclose() explicitly. 90 __FreeBSD_version bumpted to 501110. 91 9220030926: 93 kiconv(3) has been added. mount_msdosfs(8), mount_ntfs(8) and 94 mount_cd9660(8) need to be in sync with kernel. 95 9620030925: 97 Configuring a system to use IPFILTER now requires that PFIL_HOOKS 98 also be explicitly configured. Previously this dependency was 99 magically handled through some cruft in net/pfil.h; but that has 100 been removed. Building a kernel with IPFILTER but not PFIL_HOOKS 101 will fail with obtuse errors in ip_fil.c. 102 10320030923: 104 Fix a bug in arplookup(), whereby a hostile party on a locally 105 attached network could exhaust kernel memory, and cause a system 106 panic, by sending a flood of spoofed ARP requests. See 107 FreeBSD-SA-03:14.arp. 108 10920030915: 110 A change to /etc/defaults/rc.conf now causes inetd to be started 111 with `-C 60' if it is not overridden in /etc/rc.conf. This 112 causes inetd to stop accepting connections from an IP address 113 that exceeds the rate of 60 connections per minute. 114 11520030829: 116 The following rc.d scripts have been removed and should be 117 deleted from your installation: atm2.sh atm3.sh devdb 118 localdaemons network1 network2 network3. Depending on when 119 you last updated world and used mergemaster(8) you may or 120 may not have problems during the rc boot sequence. The simplest 121 solution is an 'rm -rf /etc/rc.d/*' and then 'mergemaster -i'. 122 The atm2.sh atm3.sh and devdb scripts were removed some time 123 ago, so depending on when you installed -CURRENT these scripts 124 may or may not exist on your system. 125 12620030824: 127 ATAng has been committed. You need to build world as sys/ata.h 128 has changed, and userland atacontrol depends on it. 129 If you use ATA SW raids you need "device ataraid" in your 130 kernel config file, as it is no longer pulled in automatically. 131 13220030819: 133 The OFW_NEWPCI option has been turned on in the Sparc64 GENERIC kernel. 134 Among other things, this changes the device enumeration to be 135 closer to Solaris. Be aware that, this can even cause the machine 136 to not boot without manual intervention before the fstab is adjusted. 137 13820030728: 139 All current USB and Firewire quirks in da(4) have been deprecated 140 and will be removed for 5.2. If this causes failure for your 141 umass(4) devices, enable "options DA_OLD_QUIRKS" in your kernel 142 and send the output of "camcontrol inquiry da0" to scsi@freebsd.org 143 so the quirk can be re-enabled. 144 14520030722: 146 FPU-less support has been removed from FreeBSD. Chances are you won't 147 notice. 386+387 support should still work after this change, but 148 it is now a minimum requirement for the i386 port that you have real 149 FPU hardware. 150 15120030714: 152 Some people are having problems with changes related to /rescue. 153 If you are building -j N, you will need to define NO_RESCUE. Others 154 will need to define it if /rescue has issues with their environment. 155 People should report those issues to current@. 156 15720030711: 158 gcc was upgraded to 3.3. You are advised to not build -DNOCLEAN 159 across this point. Further, it might be a good idea to remove 160 /usr/obj. 161 16220030613: [retrospective] 163 There was a small window in which sed(1) was broken. If you 164 happen to have sed(1) installed during that window, which is 165 evidenced by an inability to build world with the failure 166 given below, you need to manually build and install sed(1) 167 (and only sed(1)) before doing anything else. This is a one- 168 time snafu. Typical failure mode: 169 170 In file included from /usr/src/contrib/binutils/bfd/targets.c:1092: 171 targmatch.h:7:1: null character(s) ignored 172 targmatch.h:12:1: null character(s) ignored 173 targmatch.h:16:1: null character(s) ignored 174 : 175 176 The window of "sed(1)-uction" is from Wed Jun 4 15:31:55 2003 UTC 177 to Thu Jun 5 12:10:19 2003 UTC (from rev 1.30 to rev 1.31 of 178 usr.bin/sed/process.c). 179 18020030610: 181 Remove deprecated locale names and transition period code 182 for them, finishing switching to the new scheme. Check your 183 LANG environment variable. 184 18520030609: 186 CCD has been changed to be a fully GEOMified class. Kernel 187 and ccdconfig(8) needs to be in sync, this is particularly 188 important to remember beforehand if your source tree is on 189 a ccd device. Consider making a copy of the old ccdconfig 190 into /boot/kernel.good or wherever you keep your backup 191 kernel. 192 19320030505: 194 Kerberos 5 (Heimdal) is now built by default. Setting 195 MAKE_KERBEROS5 no longer has any effect. If you do NOT 196 want the "base" Kerberos 5, you need to set NO_KERBEROS. 197 19820030502: 199 groff has been updated. If you try to do a buildworld and 200 get an infinite loop in troff, update to May 4th or newer. If you 201 have a newer kernel than userland, you may need to set the OSRELDATE 202 to 500110 in your environment before starting a buildworld. 203 20420030501: 205 The old rc system has been removed. Please report any problems 206 to freebsd-rc@yahoogroups.com, and/or freebsd-current@freebsd.org. 207 Your personal versions of these files will not be removed, so you can 208 continue to use them. However, you should take great care when updating, 209 especially when using mergemaster, since the compatibility code that 210 utilizes these old scripts has also been removed. 211 21220030423: 213 A bug has been fixed in /dev/devctl which would cause devd 214 to hang on boot, were it not for a workaround in devd. The 215 work around in devd will be removed around 20030507. You 216 have until then to upgrade your kernel before updating 217 userland. In general, you should have a userland and 218 kernel that's in sync with each other. However, given the 219 effects of this bug (hang on boot when starting devd), some 220 allowances are made. 221 22220030329: 223 Alphas with libc from between 20030312 and 20030329 exhibit 224 floating point exceptions (FPEs), most notably in awk(1) 225 while upgrading the system through a buildworld. 226 227 So, to successfully upgrade your Alpha, you must either 228 downgrade your libc.so to a pre-20030312 version, or update 229 /usr/share/mk/bsd.cpu.mk to revision 1.26 which adds -mieee 230 to CFLAGS, then forcibly rebuild and install libc: 231 232 cd /usr/src/lib/libc && \ 233 make cleandir && make obj && \ 234 make -DNOMAN -DNOPROFILE all && \ 235 make -DNOMAN -DNOPROFILE install 236 23720030208: 238 sendmail 8.12.7 has been imported. It has one important 239 change for IPv6 users. The default submit.mc now uses 240 '[127.0.0.1]' instead of 'localhost' meaning only IPv4 is 241 used to connect to the MTA. Users on IPv6-only machines 242 will need to edit /etc/mail/submit.mc appropriately. 243 24420030128: 245 NODEVFS option has been removed and DEVFS thereby made standard. 246 This makes all references to MAKEDEV obsolete, and they should 247 be removed when convenient. 248 24920030126: 250 The name of the device for the ofw console has changed, sparc64 users 251 must run mergemaster to update their installed /etc/ttys. 252 25320030125: 254 The scheduler framework has grown a second scheduler and consequently 255 you must specify one and only one scheduler in your kernel config. 256 The cvs config files have been updated to use the old scheduler 257 which may be selected via 'options SCHED_4BSD'. If you would like 258 to try the new, much more experimental, scheduler please try 259 'options SCHED_ULE' and contribute to the arch@ discussion. 260 26120030115: 262 A new version of the wi driver has been imported into the tree. 263 One now must have device wlan in the config file for it to operate 264 properly. 265 266 In addition, there have been some changes to how wi devices are 267 configured for point to point links to bring it more in line 268 with the former way of doing things, as well as compatibility 269 with NetBSD. 270 27120021222: 272 For a period after the GCC 3.2.1 import (from 12/04 to 12/22), GCC 273 used an incompatible form of ABI for returning structures and unions 274 which FreeBSD's GCC maintainers were not aware of relative to previous 275 versions of FreeBSD. We have gone back to the ABI for now, and any 276 code compiled which is required to interoperate with other code (not 277 built at the same time) returning structs or unions should be 278 rebuilt. 279 28020021216: 281 A name change in /etc/netconfig has been reverted to stay 282 compatible with suns TIRPC and also with NetBSD. You need 283 to run mergemaster after make world. A new libc does still work 284 with an outdated /etc/netconfig for some time, but you'll get 285 a warning. This warning will be removed in 20030301. 286 28720021202: 288 The recent binutils upgrade marks a kernel flag day on 289 sparc64: modules built with the old binutils will not work 290 with new kernels and vice versa. Mismatches will result in 291 panics. Make sure your kernel and modules are in sync. 292 29320021029: 294 The value of IPPROTO_DIVERT has changed. Make sure to keep 295 your kernel, netstat, natd and any third-party DIVERT 296 consumers in sync. 297 29820021024: 299 Old, compatibility slices have been removed in GEOM kernels. 300 This means that you will have to update your /etc/fstab to 301 not use disk devices of the form /dev/ad0a. Instead, you 302 now must specify /dev/ad0s1a, or whatever slice your FreeBSD 303 partition really is on. The old device names have gone 304 away, so if you use them anywhere else, you must also adjust 305 those uses. (This doesn't affect the disks formatted in 306 the ``dangerously-dedicated'' mode.) 307 30820021023: 309 Alphas with kernels from between 20020830 and 20021023 and/or 310 rtld (ld-elf.so.1) older than 20021023 may experience problems 311 with groff while doing a buildworld (kernel: "out of memory", 312 fixed in rev 1.129 of kern/imgact_elf.c; rtld: "too few PT_LOAD 313 segments", fixed in rev 1.8 of libexec/rtld-elf/map_object.c). 314 315 So, to successfully upgrade your Alpha, you must either 316 upgrade your kernel and rtld first (which might be a bit 317 tricky), or avoid running the bootstrapped groff during the 318 "transitional" buildworld. To avoid running groff during the 319 transitional upgrade run make buildworld with -DNOMAN, 320 -DNO_SHAREDOCS, and -DNO_LPR. 321 32220020831: 323 gcc has been upgraded to 3.2. It is not all binary compatible 324 with earlier versions of gcc for c++ programs. All c++ 325 programs and libraries need to be recompiled. 326 327 Also, if you encounter g++ issues, rm /usr/include/g++/* before 328 doing an installworld to make sure that stale files are removed. 329 33020020827: 331 Our /etc/termcap now has all the entries from the XFree86 xterm 332 almost unchanged. This means xterm now supports color by default. 333 If you used TERM=xterm-color in the past you now should use 334 TERM=xterm. (xterm-color will lead to benign warnings). 335 33620020815: 337 A "bug" in gcc(1) that was hiding warning in system headers was 338 fixed. It's probably time to add -DNO_WERROR to your make line 339 again. 340 34120020729: 342 COPY is being deprecated. The 20010530 change was reverted, as 343 it causes far more pain than was expected, and to always compare 344 before installing, please use INSTALL="install -C" again. The 345 -C option is now silently ignored when used with the -d option. 346 34720020702: 348 Problems with libc_r clients like KDE and GNOME have been resolved. 349 There are still some minor problems with some signals but the 350 system is stable enough for general use again. SMP is less so than UP 351 but each can successfully complete multiple buildworlds. 352 Libkvm needs to be recompiled due to KSE. 353 35420020701: 355 Now would be a bad time to upgrade. Something in or near the 356 KSE commit totally broke programs using libc_r like KDE and 357 GNOME. 358 35920020511: 360 The k5su utility installed as part of Kerberos 5 is no longer 361 installed with the set-user-ID bit set by default. Add 362 ENABLE_SUID_K5SU=yes to /etc/make.conf to have it installed 363 with the set-user-ID bit set. 364 36520020510: 366 Gcc 3.1 debugging format (cc -g) has changed from STABS to DWARF2. 367 Unfortunately our native GDB (at version 4.18) does not understand 368 the DWARF2 debugging format. Thus you must use `gcc -gstabs+' to 369 generated debugging information for our native GDB. 370 37120020510: 372 Due to the way CVS works, it may not properly update src/contrib/gcc 373 to the 3.1 sources. The easiest fix is to `rm -rf' src/contrib/gcc 374 and then do a cvs update. 375 37620020421: 377 When exec'ing set[ug]id executables, the kernel now ensures that the 378 stdio file descriptors (0..2) are open. See FreeBSD-SA-02:23.stdio. 379 38020020404: 381 New sendmail startup scripts have been installed to make it 382 easier to use alternative MTAs with FreeBSD. Setting the rc.conf 383 variable sendmail_enable to "NO" no longer prevents any sendmail 384 daemons from starting. Instead, either set sendmail_enable to 385 "NONE" or change mta_start_script to a script for starting 386 an alternative MTA. Setting mta_start_script to "" will 387 also prevent any MTA from being started at boot. 388 38920020403: 390 UCONSOLE is no longer a valid kernel option. 391 39220020315: 393 FreeBSD 5.0 DP-1 was basically branched today. 394 39520020225: 396 Warnings are now errors in the kernel. Unless you are a developer, 397 you should add -DNO_WERROR to your make line. 398 39920020217: 400 sendmail 8.12.2 has been imported. The sendmail binary is no 401 longer a set-user-ID root binary and the infrastructure to support 402 command line mail submission has changed. Be sure to run 403 mergemaster (especially for updating /etc/rc, /etc/defaults/rc.conf, 404 and /etc/mail) and read /etc/mail/README for more details. 405 406 Due to the import of sendmail 8.12.2, a new user and group are 407 required in order for sendmail to run as a set-group-ID 408 binary. A 'make installworld' will use the new user and group 409 to set the owner and group of /var/spool/clientmqueue and will 410 fail if the new user and group do not exist. The 'smmsp' user 411 and group must be merged from src/etc/group and 412 src/etc/master.passwd before using 'make installworld'. 413 'mergemaster -p' will do this. You may need to install 414 mergemaster before this will work if you are updating from a 415 very old version of current. The updating recipe has changed 416 as of this date. 417 41820020112: 419 The preferred configuration method for PAM is now /etc/pam.d/ 420 rather than /etc/pam.conf. If you have an unmodified 421 pam.conf, just delete it after your next mergemaster run. If 422 you have local modifications, you can use 423 /usr/src/etc/pam.d/convert.pl to incorporate them into your 424 /etc/pam.d. 425 426 Please see the following url for more details: 427http://www.freebsd.org/cgi/mid.cgi?db=mid&id=<xzp6667fyoa.fsf@flood.ping.uio.no> 42820011229: 429 If anyone here is already using the new rc.conf(5) variable 430 networkfs_types, please note that it has changed 431http://www.freebsd.org/cgi/mid.cgi?db=mid&id=<9744.1009655556@axl.seasidesoftware.co.za> 432 43320011220: 434 sys/i4b/driver/i4b_ispppsubr.c has been retired. This file 435 started out its life in the ISDN4BSD project as an offspring 436 from sys/net/if_spppsubr.c, which eventually got a life of its 437 own. All the accumulated features and bugfixes of the i4b 438 version have now been merged back into the base system's 439 version now. The only user-visible change resulting from this 440 is that i4b's sppp(4) interfaces are to be managed with 441 spppcontrol(8) again, since ispppcontrol(8) has been retired 442 as well. (There has never been rc file support for 443 ispppcontrol in -current, but only in -stable. That will be 444 reverted by the time the changes are MFCed.) 445 44620011215: 447 The fdc(4) driver has been updated and now automatically 448 recognizes media in `standard' formats (like 1440 KB and 449 720 KB for a 3.5" high-density drive) when accessing the 450 default device node (e. g. /dev/fd0). The old variety of 451 floppy device nodes /dev/fd*.* is no longer present by 452 default, devices can be created (in DEVFS) on demand. They 453 will need to be customized then for `odd' densities using 454 fdcontrol(8). 455 45620011209: 457 The bugs in procfs' debugging support code have been fixed, 458 and truss(1) now works again. 459 46020011207: 461 Daily security checks have been split out to use the periodic(8) 462 scripts. Some change in configuration may be necessary. Please 463 see 464http://www.freebsd.org/cgi/mid.cgi?db=mid&id=<20011207155805.R8975@blossom.cjclark.org> 465 for details. 466 46720011204: 468 sos added VCD/SVCD support to ata driver and that needs the 469 kernel and burncd to be in sync. 470 47120011203: 472 The procfs pseudo-filesystem has now been converted to use the 473 pseudofs framework. If you have 'options PROCFS' in your 474 kernel config, you'll need to add 'options PSEUDOFS' if it's 475 not there already. 476 477 This change temporarily breaks truss(1); use ktrace(1) instead 478 until the issue has been resolved. 479 48020011202: 481 A security hole in OpenSSH involving `UseLogin yes' has been 482 patched. 483 48420011126: 485 You need to remove /usr/obj/.../usr.bin/tip before rebuilding 486 after this date. You need to do this only once. 487 48820011103: 489 Most of the awk issues have been resolved. Some rough 490 edges may be left, but for the most part things should be 491 back to "normal." For CURRENT's usual definition of "normal." 492 49320011030: 494 Awk has been upgraded to the one true awk from bell labs. Expect 495 choppy waves in the upgrade process. 496 49720011030: 498 The asr driver problem has been resolved. 499 50020011027: 501 Due to changes in other parts of the system, the asr driver 502 now causes the system to panic on boot. Do not use it pending 503 correction. Comment it out of any kernel config file that you 504 try to use from this date forward. 505 50620011025: 507 When crossbuilding, use TARGET=xxx where you used to use 508 MACHINE=xxx. You don't need to set TARGET_ARCH and TARGET, 509 unless you are changing both of them. To cross build pc98 on 510 an alpha, for example, you need to set TARGET=pc98 and 511 TARGET_ARCH=i386. 512 51320011001: 514 The kernel interface that burncd depends on has changed. 515 You must recompile both the kernel and userland applications 516 at the same time. 517 51820010929: 519 When crossbuilding, please set TARGET_ARCH rather than 520 MACHINE_ARCH to indicate the target. In the future, one will 521 set TARGET_MACHINE where you set MACHINE now. At the moment, 522 setting MACHINE alone for same MACHINE_ARCH machines works 523 (eg, you can build pc98 on an i386 machine and vice versa). 524 52520010927: 526 Some weird problems result from using ACPI on some machines. 527 To disable ACPI you can add 528 hint.acpi.0.disabled="1" 529 to /boot/loader.conf (or by putting set X=Y at the boot 530 loader "ok" prompt). 531 532 Alternatively, you can remove it from /boot/kernel/acpi.ko 533 or use the MODULES_OVERRIDE function in your kernel config 534 file and not list acpi in that list. 535 53620010924: 537 The buildworld has been fixed. You may need to install 538 the 4.x compatibility libraries for some old binaries 539 to work. Add COMPAT4X=true to your /etc/make.conf to 540 get them installed on every installworld, or execute the 541 following to get them installed only once: 542 cd src/lib/compat/compat4x.<arch> 543 make all install 544 You will see ``__stdoutp undefined'' until you do this. 545 54620010919: 547 There's a bug in the world build process. The cross-tools 548 are build with the NEW headers, but the OLD libc.a. This 549 leads to all kinds of problems with the new libc. A temporary 550 workaround is to add 551 CFLAGS="-O -pipe -D_OLD_STDIO" 552 before building world when upgrading from 4.x to current. This 553 can be removed afterwards. 554 555 A proper fix to the buildworld target is needed. 556 55720010918: 558 Peter has committed his new kthread nfs client/server code. 559 NFS may be unstable after this date. 560 56120010912: 562 KSE has hit the tree. Lots of things are now different in 563 the kernel. While a few problems were introduced in the 564 initial commit, most of the major ones have been found and 565 corrected. 566 56720010901: 568 In OLDCARD, CardBus bridges appear to be stable. The work 569 arounds described in the 20010604 entry are now no longer 570 necessary and will be ignored. Most insert/remove problems 571 have been rectified around this date. 572 57320010823: 574 named now runs as user bind and group bind rather than as 575 root. If named_enable is set to YES in /etc/rc.conf, ensure 576 that user bind is available in /etc/passwd (using vipw(8)) 577 and that group bind is available in /etc/group. Also make 578 sure that user or group bind has read (and not write) 579 permission for your name server configuration and that it 580 has read and write permission for your slave zone files and 581 directory. 582 583 If you wish to continue to run named as root (a less secure 584 alternative), add a line to /etc/rc.conf saying 585 586 named_flags= 587 58820010709: 589 The PAM libraries have had an API upgrade that is beyond 590 the ability of the shared library major number to handle. 591 It is manifested by PAM-using ports dumping core. The 592 solution is to rebuild those ports. 593 59420010628: 595 The kernel compile module has moved from src/sys/compile/FOO 596 to src/sys/${MACHINE}/compile/FOO. 597 59820010625: 599 The pccard modem issue from 20010613 has been corrected. 600 OLDCARD support is still a little weak in -current. slot 1 is 601 known not to work on some TI based cardbus bridges. Some 602 cardbus bridges do not properly detect insert/removal events. 603 IRQ configuration needs more safety belts. 604 60520010617: 606 Softupdates problems have been corrected. 607 60820010614: 609 Peter ripped out the linkerset support. You must, as always, 610 rerun config after you cvsup if you are using the traditional 611 kernel building methods. 612 61320010613: 614 pccard modems may not work with current after 20010604 date. Some 615 do, others result in panics. *MAKE*SURE* that you update your 616 config and /etc/rc.conf ala the 20010604 entry, or you will have 617 problems (this issue will be fixed, it just hasn't been yet). 618 61920010613: 620 SOFTUPDATES seem to be broken since the middle of May or so. Do not 621 use them in current. You can disable softupdates on all mounted 622 partitions, or remove SOFTUPDATES the kernel config file. 623 62420010612: 625 After Peter's commits to the hints code, people have been noticing 626 that certain devices are attached (or try to) twice. This is due 627 to having both static hints as well as a /boot/device.hints. To 628 work around this issue, please use only one or the other mechanism 629 until this bug is fixed. 630 631 Please note that a feature of config is that if you have config 632 file FOO and FOO.hints, it automatically adds FOO.hints to the 633 hints.c file, whether you want it to or not. 634 63520010610: 636 Locale names have changed to match other systems better. 637 63820010604: 639 pccard support for pci cards has been committed. You must change 640 your /etc/pccard.conf irq lines. It must match the irq used by 641 pcic device. Interrupt storms may result if you fail to do this. 642 Interrupt storms look a lot like a hang. 643 644 You must also install a new pccardd, otherwise you will get an 645 interrupt storm at card reset time (just after it tells you what 646 it is). 647 648 pccardd_flags="-I" is necessary for the time being. It tells pccardd 649 not to ask the kernel if the interrupt is really free or not before 650 using it. You can either change the /etc/pccard.conf irq lines to 651 match pcic, or add "-i X" to the pccardd_flags. 652 65320010530: 654 INSTALL=install -C is being deprecated. If you want to do this, 655 use COPY=-C instead. The former method will be supported for only 656 a limited time. If you see 657 658install: warning: the -d and -C options may not be specified together 659 660 in your makeworld, then you need to migrate towards using 661 COPY=-C. 662 66320010525: 664 It appears that vm is now stable enough to use again. However, 665 there may be other problems, so caution is still urged. alpha 666 definitely is in bad shape. 667 66820010521: 669 Minor repo damage has happened. This may cause problems 670 with cvsup of ports. If you get errors, please see 671 http://www.FreeBSD.org/cgi/query-pr.cgi?pr=27495 672 at the bottom for details on a workaround. The error message 673 is 674Updater failed: Cannot delete "/usr/ports/www/jakarta-tomcat/files": Directory not empty 675 67620010520: 677 Vm and/or swapping are busted on -current. Please be patient. 678 67920010519: 680 pccard has had much reorganizational work done to it over 681 the past few days. Everything should still work, but if 682 not, please contact imp@freebsd.org. 683 68420010517: 685 ata ioctl changed. Make sure to recompile both kernel and 686 userland at the same time. 687 68820010517: 689 New ncurses imported. 690 69120010512: 692 DEVFS is now opt out, not opt in. Barring major problems, this 693 will be the only way to go starting July 1. 694 69520010504: 696 OpenSSH has been updated to 2.9. Some defaults are different, 697 including RhostsRSAAuthentication, which changes from yes to no. 698 69920010502: 700 Perl breakage in 20010501 was corrected at 14:18:33 PDT. 701 70220010501: 703 Building perl was broken at 02:25:25 PDT. 704 70520010430: 706 The bug in 20010429 was corrected at 07:35:37 PDT. It is safe to 707 go back in the water. 708 70920010429: 710 A bad bug was committed at 04:48:42 PDT. Don't use kernels after 711 this date, but before the correction date. 712 71320010423: 714 old fsck and new kernel interactions appear to have been fixed. 715 71620010411: 717 fsck and the kernel were changed to handle some optimizations 718 to directory layout. This breaks backward compatibility. 719 Update only if you understand that you must not use the old 720 fsck with the new kernel ever. 721 72220010330: 723 fsck has changed the meaning of the pass column in /etc/fstab. 724 Please see the cvs commit to fsck.8 or the fsck.8 man page for 725 details. It is unclear if changes to /etc/fstab are necessary. 726 72720010319: 728 portmap had changed name to rpcbind for maximum POLA in your 729 current world. /etc/hosts.{allow,deny} needs changes. nfs and 730 other rpc based programs that rely on portmapper will not work 731 without updates to /etc/hosts.{allow,deny} and /etc/netconfig. 732 73320010315: 734 ata subsystem changes. ATA_ENABLE_ATAPI_DMA, ATA_ENABLE_WC 735 and ATA_ENABLE_TAGS are no longer kernel options. They have 736 been replaced by tunables. See ata.4 for details. 737 73820010312: 739 The fxp driver was converted to use miibus. If you compile 740 fxp into your kernel statically, you will need to add miibus. 741 74220010312: 743 The wi device now defaults to BSS (infrastructure) mode 744 instead of ad-hoc. 745 74620010310: 747 /dev/urandom should be a symbolic link to /dev/random now. 748 Users of current not using DEVFS need to run MAKEDEV std. 749 ssh might not work if you don't. 750 75120010303: 752 The ed driver has been updated. It now allows mii attachments, 753 which means that you must include the miibus in your kernel if 754 you use the ed driver. 755 75620010220: 757 The problems with libc have been corrected. It is now mostly 758 safe to go back into the water. 759 76020010211: 761 The size of FILE was changed. This breaks upgrading. If 762 you must upgrade, be prepared for pain. It also breaks almost 763 all binaries that you've compiled on -current. You are warned 764 that before upgrading would be a good time to do a level 0 765 dump of your system. No, really, I mean it this time. 766 767 To get to the new system, you'll need to use the following 768 workaround. Hopefully this can be sorted out so that we 769 don't have to move this to the updating section. 770 771 To get around the installworld problem, do: 772 # cd /usr/src/usr.bin/sed 773 # make install 774 # cd /usr/src 775 # make installworld 776 If that doesn't work, then try: 777 # make -k installworld 778 # make installworld 779 78020010207: 781 DEVFS is now the default. If you use vinum, make sure that you 782 do not include devfs in your kernel as problems result. 783 78420010205: 785 FFS_ROOT and CD9660_ROOT have been removed or deprecated. 786 Remove them from your config. 787 78820010122: 789 ****************************** WARNING ****************************** 790 buildkernel has been changed slightly 791 ****************************** WARNING ****************************** 792 KERNCONF replaces the variable KERNEL for buildkernel. You 793 should update your scripts and make.conf accordingly. 794 79520010119: 796 config has changed to allow DEV_FOO as a replacement for NFOO. 797 This requires a new config to build correctly. 798 79920010116: 800 The kernel option I386_CPU is now mutually exclusive with the 801 other cpu types. If you have an i386 system, be sure that it 802 only had this line. Remove it for all other configurations. 803 80420010110: 805 Changes to the kernel require it and burncd be in sync. 806 80720010102: 808 Everyone who has hw.sndunit set to something in 809 /etc/sysctl.conf, it is now hw.snd.unit. 810 81120010101: 812 ex and vi were broken by some changes to sys/queue.h. If you 813 have a bad vi, you will see make buildworld fail with a core 814 dump while building termcap. You can work around this problem 815 by adding -k to your make buildworld. This will cause the 816 build to complete and install a new vi. Once that's done, you 817 can rebuild again without the -k to pick up anything that 818 might have been ignored by the -k option. 819 820 Others have suggested that you can just rebuild libc if your 821 vi/ex is dynamically linked, but I've not received any reports 822 of this working. 823 82420001228: 825 There have been some changes to libcrypt in -current. The 826 libscrypt/libdescrypt symlink silliness is gone and the installed 827 libcrypt is fully functional. Be aware of this. 828 82920001218: 830 Linksys Fast Ethernet PCCARD cards supported by the ed driver 831 now require the addition of flag 0x80000 to their config line 832 in pccard.conf(5). This flag is not optional. These Linksys 833 cards will not be recognized without it. 834 83520001205: 836 Important new FreeBSD-version stuff: PAM support has been worked 837 in, partially from the "Unix" OpenSSH version. This requires 838 adding the following in pam.conf: 839 840 sshd auth sufficient pam_skey.so 841 sshd auth required pam_unix.so try_first_pass 842 sshd session required pam_permit.so 843 84420001031: 845 cvs updated to 1.11. 846 84720001020: 848 The random device needs more entropy, so you need to make sure 849 that you've run mergemaster to get a /etc/rc which will seed 850 /dev/random. If you don't and the system hangs after ldconfig, 851 then banging on the keyboard randomly until it unhangs is one 852 workaround. 853 85420001010: 855 ****************************** WARNING ****************************** 856 Sendmail has been updated. 857 ****************************** WARNING ****************************** 858 o mail.local(8) is no longer installed as a set-user-id binary. 859 o sendmail(8) is now built with STARTTLS support unless NO_OPENSSL 860 is set. 861 o The default /etc/mail/sendmail.cf disables the SMTP EXPN and VRFY 862 commands. 863 o Now using sendmail's version of vacation(1). 864 o The sendmail cf building tools (contrib/sendmail/cf) are installed 865 in /usr/share/sendmail/cf. 866 o sendmail.cw changed to local-host-names 867 868 More details can be found at 869 http://people.freebsd.org/~imp/UPDATING/sendmail-20001010 870 87120001009: 872 The ports tree's new layout is in place. Be sure to update 873 your entire ports tree, or you will have problems. 874 87520001006: 876 The perl build procedure no longer installs miniperl, nor uses 877 the installed miniperl. It is recommended that you delete 878 /usr/bin/miniperl. 879 88020001005: 881 This weekend the ports tree will be updated to a new layout. 882 It will be in an inconsistent state until noted in the UPDATING 883 file, or with asami-san's message to the relevant mailing 884 lists. With this new layout, you'll need to update the whole 885 tree for anything to work. 886 88720000928: 888 There was a change in the passwd format. Need more information. 889 89020000916: 891 /boot/kernel/kernel.ko -> /boot/kernel/kernel change has taken 892 place. Please update boot loader (not the boot blocks) at the 893 same time as your kernel. 894 89520000914: 896 The new pmtimer device is necessary for laptops. Failure to 897 include the device will cause suspended laptops losing time 898 when they resume. Include 899 device pmtimer 900 in your config file and 901 hint.pmtimer.0.at="isa" 902 to your /boot/device.hints file. 903 90420000911: 905 The random device has been turned into a (pseudo-)device, 906 rather than an option. The supplied kernel config files have 907 been updated. You will need to do something similar in your 908 own kernel config file. 909 Remove: 910 options RANDOMDEV 911 Add: 912 device random 913 If you prefer to load the loadable module, you need to do 914 nothing. 915 91620000909: 917 The random device module has been renamed from randomdev.ko to 918 random.ko. You will need to edit your /boot/loader.conf to 919 reflect this if you load this module at boot time. 920 The line should read: 921 random_load="YES" 922 92320000907: 924 The SMPNG commit has happened. It should work, but if it 925 doesn't, fallback to the PRE_SMPNG CVS tag. There are likely 926 to be a variety of minor issues. Please see 20000905 to make 927 sure you don't have model loading problems which might at 928 first blush appear related to SMP. 929 93020000906: 931 nsswitch has been imported from NetBSD. Among other things, 932 this means that /etc/host.conf is no longer used. See 933 nsswitch.conf(5) instead. Note that at boot time rc.network 934 will attempt to produce a new nsswitch.conf file for you if you 935 don't have one, and you have host.conf. 936 93720000905: 938 The ucred structure changed size. This breaks the interface 939 that mountd uses. Trying to use an older mountd with a newer 940 kernel guarantees a panic. This means that you need to use 941 kernels newer than today only with matching mountd, but you 942 needed to do that anyway with the boot loader changes. 943 94420000905: 945 The boot loader has been updated. The new default kernel is 946 now /boot/kernel/kernel.ko. The new default module location 947 is /boot/kernel. 948 949 You *MUST* upgrade your boot loader and kernel at the same time. 950 The easiest way to do this is to do the buildworld/buildkernel/ 951 installkernel/installworld dance. 952 953 Furthermore, you are urged to delete your old /modules directory 954 before booting the new kernel, since kldload will find stale 955 modules in that directory instead of finding them in the correct 956 path, /boot/kernel. The most common complaint that this cures 957 is that the linux module crashes your machine after the update. 958 959 if [ ! -d /boot/kernel.old ]; then 960 mv /modules.old /boot/kernel.old 961 chflags noschg /kernel.old 962 mv /kernel.old /boot/kernel.old/kernel.ko 963 chflags schg /boot/kernel.old/kernel.ko 964 fi 965 96620000904: 967 A new issue with the sendmail upgrade has come to light. 968 /etc/aliases has moved to /etc/mail/aliases. Mergemaster will 969 incorrectly install the default aliases in /etc/mail rather than 970 move the old one from /etc. So you'll need to manually move the 971 file, create a symbolic link, remove the old /etc/aliases.db and 972 run newaliases. For safety sake, you should stop sendmail 973 while doing this and run the upgrade when locally sourced email 974 is not likely to be generated. 975 97620000825: 977 /boot/device.hints is now required for installkernel to 978 succeed. You should copy GENERIC.hints for your architecture 979 into /boot/device.hints. If and only if you compile hints 980 into your kernel, then this file may be empty. Please note, 981 if you have an empty or missing /boot/device.hints file and 982 you neglected to compile hints into your kernel, no boot 983 messages will appear after the boot loader tries to start the 984 kernel. 985 98620000821: 987 If you do NOT have ``options RANDOMDEV'' in your kernel and 988 you DO want the random device then add randomdev_load="YES" to 989 /boot/loader.conf. 990 99120000812: 992 suidperl is now always built and installed on the system, but 993 with permissions of 511. If you have applications that use 994 this program, you are now required to add ENABLE_SUIDPERL=true 995 to /etc/make.conf. If you forget to do this, 996 chmod 4511 /usr/bin/suidperl 997 will fix this until the next build. 998 99920000812: 1000 sendmail has been updated from 8.9.3 to 8.11.0. Some of the more 1001 visible changes that may immediately affect your configuration 1002 include: 1003 - New default file locations from src/contrib/sendmail/cf/README 1004 - newaliases limited to root and trusted users 1005 - MSA port (587) turned on by default 1006 - New queue file naming system so can't go from 8.11 -> 8.9 1007 - FEATURE(`rbl') renamed to FEATURE(`dnsbl') 1008 - FEATURE(`nullclient') is more full featured 1009 - FEATURE(`nouucp') requires an argument: `reject' or `nospecial' 1010 - mail.local FreeBSD-only -b option changed to -B 1011 - See src/contrib/sendmail/RELEASE_NOTES for more info 1012 101320000810: 1014 suidperl (aka sperl) is no longer build by default. You must 1015 specifically define BUILD_SUIDPERL to "true" for it to be build. 1016 Furthermore, we recommend that you remove /usr/bin/sperl* and 1017 /usr/bin/suidperl files from your system unless you have a 1018 specific use for it. 1019 102020000729: 1021 Networking defaults have been tightened. Anybody upgrading 1022 /etc/defaults/rc.conf needs to add the following lines to 1023 /etc/rc.conf if they want to have the same setup 1024 afterwards (unless the variables already are set, of course): 1025 # Enable network daemons for user convenience. 1026 inetd_enable="YES" 1027 portmap_enable="YES" 1028 sendmail_enable="YES" 1029 103020000728: 1031 If you have null_load="YES" in your /boot/loader.conf, you 1032 will need to change that to nullfs_load="YES". 1033 103420000728: 1035 The "installkernel" target has changed slightly. Now even if 1036 you override KERNEL e.g. 'make installkernel KERNEL=MYKERNEL' 1037 it will install the MYKERNEL file (built with the buildkernel 1038 target) as /kernel rather than /MYKERNEL. Those who have 1039 updated their /boot/loader.conf files to point to /MYKERNEL 1040 should remove that entry or perform manual rename of /kernel 1041 to /MYKERNEL. 1042 104320000711: 1044 If you use CVSUP or CTM to get CVS trees, AND you used to get 1045 the old crypto files from internat.freebsd.org AND you check 1046 out files from the CVS tree with the cvs command, please read 1047 http://people.freebsd.org/~imp/internat.txt 1048 for details on potential problems that you might have and how 1049 to get around them. 1050 1051 If you are merely a mirror, or don't answer yes to each of the 1052 clauses above, you needn't worry. 1053 105420000711: 1055 /etc/security has been updated to print the inode number of 1056 setuid programs that have changed. You will see a large spike 1057 in the number of changed programs the first time when you run 1058 mergemaster to get a new /etc/security. 1059 106020000710: 1061 /dev/random now has good entropy collection (from the keyboard 1062 and sysmouse drivers). Please ensure that either `options 1063 RANDOMDEV' is present in your kernel config file or that 1064 `randomdev_load="YES"' is in your /boot/loader.conf. If you do 1065 not have the /dev/random driver, OpenSSL (and consequently 1066 lots of crypto tools (like SSH)) will fail with strange 1067 errors. (see below, 20000624). 1068 1069 FreeBSD-current is safe again to run Crypto. 1070 107120000709: 1072 phk made the malloc default options AJ. This may slow things 1073 down and uncover other latent bugs in the code. If you need to 1074 run at full speed, you can disable this by doing the following: 1075 ln -s aj /etc/malloc.conf 1076 107720000706: 1078 libftpio's version was accidentally bumped a few days ago. This 1079 has been corrected. You may need to remove /usr/lib/libftpio.so.6 1080 before doing your next buildworld/installworld pair. It certainly 1081 won't hurt to remove it before the update procedure. It will 1082 break fetch until a new one is built, but ftp can be used in the 1083 interim if needed. 1084 108520000705: 1086 The crypto packages have changed for the cvsup. This has been done 1087 in a backward compatible way, but the old packages will go away at 1088 some point in the future. Look at /usr/share/examples/cvsup for 1089 details. 1090 109120000704: 1092 With the new sys/modules/sound/drivers/*, you will need to 1093 set SYSDIR until you do an installworld after July 7th. 1094 109520000704: 1096 rc.shutdown and rc will now call the rc.d scripts with start 1097 or stop. This may cause some harmless warnings from older 1098 rc.d scripts that haven't been updated. 1099 110020000630: 1101 The libfetch based version of fetch has gone into the tree. 1102 Minor problems may result on some of the less popular sites, 1103 which should be reported to des@freebsd.org. 1104 110520000625: 1106 From approximately this date forward, one must have the crypto 1107 system installed in order to build the system and kernel. 1108 While not technically strictly true, one should treat it as 1109 required and grab the crypto bits. If you are grabbing CVS 1110 trees, src-all and cvs-crypto should be treated as if they 1111 were required. You should check with the latest collections 1112 to make sure that these haven't changed. 1113 111420000624: 1115 Mark Murray just committed the first parts of a cleanup of 1116 /dev/zero, et al. This is also cleaning up /dev/random. 1117 The entropy is disconnected, so DO NOT USE VERSIONS OF FREEBSD 1118 -CURRENT FROM THIS POINT to 2000710 for cryptographic services 1119 until Mark can merge in the fixes to this work in progress. 1120 openssh and openssl should not be used to generate keys from this 1121 date to the completion of the work. 1122 1123 If you must operate at this reduced level of security, add ' 1124 options RANDOMDEV' to your kernel or modload the randomdev 1125 module. You may also need to copy a new MAKEDEV to /dev and 1126 recreate the random and urandom devices. 1127 112820000622: 1129 The license on the softupdates is now a standard 2 clause 1130 BSD license. You may need to remove your symbolic links 1131 that used to be required when updating. 1132 113320000621: 1134 Scott Flatman <sf@aracnet.com> sent in a decent write-up on 1135 the config file update procedure. 1136 http://people.freebsd.org/~imp/config-upd.html 1137 NOTE: LINT is gone. It has been replaced with NOTES. NOTES 1138 isn't buildable. However, you can generate a LINT file: 1139 cd /sys/<ARCH>/conf && make LINT 1140 114120000620: 1142 Binutils 2.10 have hit the tree, or will shortly. As soon 1143 as they do, the problem noted in 20000522 will be resolved and 1144 that workaround will no longer be required. 1145 114620000615: 1147 phk removed the compatibility creation of wd devices in the 1148 ad driver. If you haven't done so already, you must update 1149 your fstab, etc to use the ad devices instead of the wd 1150 devices. 1151 1152 In addition, you'll need to update your boot blocks to a 1153 more modern version, if you haven't already done so. Modern 1154 here means 4.0 release or newer (although older releases 1155 may work). 1156 115720000612: 1158 Peter took an axe to config(8). Be sure that you read his mail 1159 on the topic before even thinking about updating. You will 1160 need to create a /boot/device.hints or add a hints directive 1161 to your config file to compile them in statically. The format 1162 of the config file has changed as well. Please see GENERIC or 1163 NEWCARD for examples of the new format. 1164 1165 Indirectly, this also breaks USERCONFIG. Unless a newer entry 1166 says that it has been fixed, assume that must use the hints mechanism 1167 in the loader if you need to use a machine with very old ISA cards 1168 in it. 1169 117020000522: 1171 A new set of binutils went into the tree today. Anybody 1172 building a kernel after this point is advised that they need 1173 to rebuild their binutils (or better yet do a 1174 buildworld/installworld) before building a new kernel. 1175 1176 Due to bugs in binutils, using malloc options (eg /etc/malloc.conf 1177 or MALLOC_OPTIONS env var) J will cause ld to dump core. It 1178 is recommended that you don't set this option until the problem 1179 is resolved. 1180 118120000513: 1182 The ethernet drivers were all updated to clean up the BPF handling. 1183 118420000510: 1185 The problems with boot blocks on the alphas have been corrected. 1186 This will require some care in updating alphas. A new libstand 1187 is requires for the boot blocks to build properly. 1188 118920000503: 1190 Recompile all kld modules. Proper version dependency info 1191 is now available. 1192 119320000502: 1194 Modules have been disconnected from the buildworld tree and 1195 connected to the kernel building instead. 1196 119720000427: 1198 You may need to build gperf 1199 cd /usr/src/gnu/usr.bin/gperf && make depend all install 1200 when upgrading from 4.0 -> current. The build system now uses 1201 an option only in -current. 1202 120320000417: 1204 The method that we brand ELF binaries has changed to be more 1205 acceptable to the binutils maintainers. You will need to 1206 rebrand your ELF binaries that aren't native. One problem 1207 binary is the Linux ldconfig. After your make world, but 1208 before you reboot, you'll need to issue: 1209 brandelf -t Linux /compat/linux/sbin/ldconfig 1210 if you have Linux compatibility enabled on your machine. 1211 121220000320: 1213 If you have really bad/marginal IDE drives, you may find they 1214 don't work well. Use pio mode instead. The easiest way to 1215 cope if you have a problem combination is to add: 1216 /sbin/sysctl hw.ata.ata_dma=0 1217 to the start of /etc/rc.conf. 1218 121920000319: 1220 The ISA and PCI compatibility shims have been connected to the 1221 options COMPAT_OLDISA and COMPAT_OLDPCI. If you are using old 1222 style PCI or ISA drivers (i.e. tx, voxware, etc.) you must 1223 include the appropriate option in your kernel config. Drivers 1224 using the shims should be updated or they won't ship with 1225 5.0-RELEASE, targeted for 2001. 1226 122720000318: 1228 We've entered the traditional post release dumping party. 1229 Large kernel changes are being committed and are in the 1230 works. It is important to keep the systems' klds and kernel 1231 in sync as kernel interfaces and structures are changing. 1232 Before reporting kernel panics, make sure that all modules 1233 that you are loading are up to date. 1234 123520000315: 1236 If you are upgrading from an older version of FreeBSD, you 1237 need to update your boot blocks as well. 'disklabel -B ad0' 1238 will do the trick. This isn't critical until you remove your 1239 wd device entries in /dev, at which point your system will not 1240 boot. 1241 124220000315: 1243 4.0 RELEASE shipped. Please see the 4.0 UPDATING file for how 1244 to upgrade to 4.0 from 3.x. 1245 1246COMMON ITEMS: 1247 1248 General Notes 1249 ------------- 1250 Avoid using make -j when upgrading. From time to time in the 1251 past there have been problems using -j with buildworld and/or 1252 installworld. This is especially true when upgrading between 1253 "distant" versions (eg one that cross a major release boundary 1254 or several minor releases, or when several months have passed 1255 on the -current branch). 1256 1257 Sometimes, obscure build problems are the result of environment 1258 poisoning. This can happen because the make utility reads its 1259 environment when searching for values for global variables. 1260 To run your build attempts in an "environmental clean room", 1261 prefix all make commands with 'env -i '. See the env(1) manual 1262 page for more details. 1263 1264 To build a kernel 1265 ----------------- 1266 If you are updating from a prior version of FreeBSD (even one just 1267 a few days old), you should follow this procedure. With a 1268 /usr/obj tree with a fresh buildworld, 1269 make -DALWAYS_CHECK_MAKE buildkernel KERNCONF=YOUR_KERNEL_HERE 1270 make -DALWAYS_CHECK_MAKE installkernel KERNCONF=YOUR_KERNEL_HERE 1271 1272 To just build a kernel when you know that it won't mess you up 1273 -------------------------------------------------------------- 1274 cd src/sys/{i386,alpha}/conf 1275 config KERNEL_NAME_HERE 1276 cd ../../compile/KERNEL_NAME_HERE 1277 make depend 1278 make 1279 make install 1280 1281 If this fails, go to the "To build a kernel" section. 1282 1283 To rebuild everything and install it on the current system. 1284 ----------------------------------------------------------- 1285 # Note: sometimes if you are running current you gotta do more than 1286 # is listed here if you are upgrading from a really old current. 1287 1288 <make sure you have good level 0 dumps> 1289 <maybe fix /etc/fstab> [7] 1290 make buildworld 1291 make buildkernel KERNCONF=YOUR_KERNEL_HERE 1292 make installkernel KERNCONF=YOUR_KERNEL_HERE 1293 [1] 1294 <reboot in single user> [3] 1295 mergemaster -p [5] 1296 make installworld 1297 mergemaster [4] 1298 <reboot> 1299 1300 1301 To cross-install current onto a separate partition 1302 -------------------------------------------------- 1303 # In this approach we use a separate partition to hold 1304 # current's root, 'usr', and 'var' directories. A partition 1305 # holding "/", "/usr" and "/var" should be about 2GB in 1306 # size. 1307 1308 <make sure you have good level 0 dumps> 1309 <boot into -stable> 1310 make buildworld 1311 <maybe newfs current's root partition> 1312 <mount current's root partition on directory ${CURRENT_ROOT}> 1313 make installworld DESTDIR=${CURRENT_ROOT} 1314 make buildkernel KERNCONF=YOUR_KERNEL_HERE 1315 cp /usr/src/sys/${ARCH}/conf/GENERIC.hints \ 1316 ${CURRENT_ROOT}/boot/device.hints # as needed 1317 make installkernel KERNCONF=YOUR_KERNEL_HERE DESTDIR=${CURRENT_ROOT} 1318 cd /usr/src/etc; make distribution DESTDIR=${CURRENT_ROOT} # if newfs'd 1319 cp /etc/fstab ${CURRENT_ROOT}/etc/fstab # if newfs'd 1320 <edit ${CURRENT_ROOT}/etc/fstab to mount "/" from the correct partition> 1321 <reboot into current> 1322 <do a "native" rebuild/install as described in the previous section> 1323 <maybe install compatibility libraries from /usr/src/lib/compat> 1324 <reboot> 1325 1326 1327 To upgrade in-place from 4.x-stable to current 1328 ---------------------------------------------- 1329 # 5.x uses more space than 4.x. Also, the location of kernel 1330 # modules has changed. If you are installing 5.0 onto a 4.x 1331 # system, you'll need about 30MB of free disk space on your / 1332 # partition. If you have less than this, you may encounter difficult 1333 # to back out of problems with this procedure. If /tmp is on 1334 # the / partition, you may want to completely remove all its content 1335 # before upgrading, as this can be a common source of shortage of 1336 # space on /. 1337 1338 <make sure you have good level 0 dumps> 1339 <maybe fix /etc/fstab> [7] 1340 make buildworld [9] 1341 make buildkernel KERNCONF=YOUR_KERNEL_HERE [8] 1342 cp src/sys/${MACHINE}/conf/GENERIC.hints /boot/device.hints [2] 1343 make installkernel KERNCONF=YOUR_KERNEL_HERE 1344 cd src/sys/boot ; make install [6] 1345 [1] 1346 <reboot in single user> [3] 1347 mergemaster -p [5] 1348 rm -rf /usr/include/g++ 1349 make installworld 1350 mergemaster [4] 1351 <reboot> 1352 1353 Make sure that you've read the UPDATING file to understand the 1354 tweaks to various things you need. At this point in the life 1355 cycle of current, things change often and you are on your own 1356 to cope. The defaults can also change, so please read ALL of 1357 the UPDATING entries. 1358 1359 Also, if you are tracking -current, you must be subscribed to 1360 freebsd-current@freebsd.org. Make sure that before you update 1361 your sources that you have read and understood all the recent 1362 messages there. If in doubt, please track -stable which has 1363 much fewer pitfalls. 1364 1365 [1] If you have third party modules, such as vmware, you 1366 should disable them at this point so they don't crash your 1367 system on reboot. 1368 1369 [2] If you have legacy ISA devices, you may need to create 1370 your own device.hints to reflect your unique hardware 1371 configuration. 1372 1373 [3] From the bootblocks, boot -s, and then do 1374 fsck -p 1375 mount -u / 1376 mount -a 1377 cd /usr/src 1378 adjkerntz -i # if CMOS is wall time 1379 Also, when doing a major release upgrade, it is required that 1380 you boot into single user mode to do the installworld. 1381 For the 4.x -> 5.0 upgrade, you will also see many messages about 1382 needing to recompile your userland. These are harmless and can 1383 be ignored while you proceed to the next step. 1384 1385 [4] Note: This step is non-optional. Failure to do this step 1386 can result in a significant reduction in the functionality of the 1387 system. Attempting to do it by hand is not recommended and those 1388 that pursue this avenue should read this file carefully, as well 1389 as the archives of freebsd-current and freebsd-hackers mailing lists 1390 for potential gotchas. 1391 1392 [5] Usually this step is a noop. However, from time to time 1393 you may need to do this if you get unknown user in the following 1394 step. It never hurts to do it all the time. You may need to 1395 install a new mergemaster (cd src/usr.sbin/mergemaster && make 1396 install) after the buildworld before this step if you last updated 1397 from current before 20020224 or from -stable before 20020408. 1398 1399 [6] 4.x boot loader can be used to boot a 5.x system, however 1400 it is difficult to do that at best. If you wish to try, then 1401 you should interrupt the boot and at the ok prompt type: 1402 ok unload 1403 ok boot /boot/kernel/kernel 1404 If this fails to work, you must install a new boot loader as 1405 described here. 1406 1407 [7] Before you upgrade, please make sure that you are not using 1408 compatibility slices. These are device names of the form, on i386 1409 and other architectures that use MBR slicing, /dev/ad0a without the 1410 actual slice name. Chances are excellent that these will break. 1411 You generally must update these entries to use the post FreeBSD 1412 2.x form of /dev/ad0s1a. 1413 1414 [8] In order to have a kernel that can run the 4.x binaries 1415 needed to do an installworld, you must include the COMPAT_FREEBSD4 1416 option in your kernel. Failure to do so may leave you with a system 1417 that is hard to boot to recover. 1418 1419 [9] When checking out sources, you must include the -P flag to have 1420 cvs prune empty directories. 1421FORMAT: 1422 1423This file contains a list, in reverse chronological order, of major 1424breakages in tracking -current. Not all things will be listed here, 1425and it only starts on March 15, 2000. Updating files can found in 1426previous releases if your system is older than this. 1427 1428Copyright information: 1429 1430Copyright 1998, 2002 M. Warner Losh.
