UPDATING revision 126757
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 2020040308: 21 The packet filter (pf) is now installed with the base system. Make 22 sure to run mergemaster -p before installworld to create required 23 user accounts. If you do not want to build pf with your system you 24 can use the NO_PF knob in make.conf. 25 Also note that pf requires "options PFIL_HOOKS" in the kernel. The 26 pf system consists of the following three devices: 27 device pf # required 28 device pflog # optional 29 device pfsync # optional 30 3120040303: 32 If you are having trouble with the libc_r -> libpthread transition 33 (see the 20040130 entry), place the following lines at the top of 34 /etc/libmap.conf: 35 36 libc_r.so.5 libpthread.so.1 37 libc_r.so libpthread.so 38 39 This will cause all programs and libraries linked against libc_r 40 to use libpthread instead. 41 4220040226: 43 Some sshd configuration defaults have changed: protocol version 1 44 is no longer enabled by default, and password authentication is 45 disabled by default if PAM is enabled (which it is by default). 46 OpenSSH clients should not be affected by this; other clients may 47 have to be reconfigured, upgraded or replaced. 48 4920040225: 50 The ABIs defined in <resolv.h> and <netdb.h> have been updated 51 to support improved reentrancy. Multi-threaded programs that 52 reference the "_res" or "h_errno" symbols may experience some 53 problems if they are not recompiled. Single-threaded programs 54 should remain unaffected. 55 5620040225: 57 routed has been updated in the base system from the vendor 58 sources, routed v2.27, from rhyolite.com. This change means that 59 for users who use RIP's MD5 authentication feature, FreeBSD 60 -CURRENT's routed is now incompatible with previous versions 61 of FreeBSD; however it is now compatible with implementations 62 from Sun, Cisco and other vendors. 63 6420040224: 65 The tcpcb structure has changed and makes a recompile of libkvm 66 and related userland network utilities neccessary. 67 6820040222: 69 The cdevsw structure has changed in two externally visible ways. 70 First, the sense of the D_GIANT flag has changed to D_NEEDSGIANT. 71 Second, the d_version field must be filled in with D_VERSION. 72 Drivers outside the tree will need to be updated. 73 7420040207: 75 The /etc/rc.d/ttys script has been removed. It is no longer 76 necessary since devfs has been mandatory for some time. 77 7820040130: 79 libkse has been renamed back to libpthread and is now the 80 default threads library. The gcc -pthread option has also 81 been changed to link to libpthread instead of libc_r. For 82 alpha and sparc64 machines, libkse is not renamed and links 83 are installed so that libpthread points to libc_r. Until 84 the ports system is updated to handle this change, it is 85 recommended that folks install an /etc/libmap.conf(5) that 86 maps libc_r to libpthread. If you have any binaries or 87 libraries linked to libkse, then it is also recommended 88 that you map libkse to libpthread. Anyone that is using 89 nvidia supplied drivers and libraries should use a libmap.conf 90 that maps libpthread to libc_r since their drivers/libraries 91 do not work with libpthread. 92 9320040125: 94 ULE has entered into its probationary period as the default scheduler 95 in GENERIC. For the average user, interactivity is reported to be 96 better in many cases. On SMP machines ULE will be able to make more 97 efficient use of the available parallel resources. If you are not 98 running it now, please switch over, replacing the kernel option 99 SCHED_4BSD with SCHED_ULE. 100 10120040125: 102 Move LongRun support out of identcpu.c, where it hardly 103 belongs, into its own file and make it opt-in, not mandatory, 104 depending on CPU_ENABLE_LONGRUN config(8) option. 105 10620031213: 107 src/lib/libc/gen/initgroups.c:1.8 now causes logins to fail 108 if the login process is unable to successfully set the 109 process credentials to include all groups defined for the 110 user. The current kernel limit is 16 groups; administrators 111 may wish to check that users do not have over 16 groups 112 defined, or they will be unable to log in. 113 11420031203: 115 The ACPI module has been reactivated. It is no longer required 116 to compile ACPI support into kernels statically. 117 11820031112: 119 The statfs structure has been updated with 64-bit fields to 120 allow accurate reporting of multi-terabyte filesystem 121 sizes. You should build world, then build and boot the new kernel 122 BEFORE doing a `installworld' as the new kernel will know about 123 binaries using the old statfs structure, but an old kernel will 124 not know about the new system calls that support the new statfs 125 structure. 126 Note that the backwards compatibility is only present when the 127 kernel is configured with the COMPAT_FREEBSD4 option. Since 128 even /bin/sh will not run with a new kernel without said option 129 you're pretty much dead in the water without it. Make sure you 130 have COMPAT_FREEBSD4! 131 Running an old kernel after a `make world' will cause programs 132 such as `df' that do a statfs system call to fail with a bad 133 system call. Marco Wertejuk <wertejuk@mwcis.com> also reports 134 that cfsd (ports/security/cfs) needs to be recompiled after 135 these changes are installed. 136 137 ****************************DANGER******************************* 138 139 DO NOT make installworld after the buildworld w/o building and 140 installing a new kernel FIRST. You will be unable to build a 141 new kernel otherwise on a system with new binaries and an old 142 kernel. 143 14420031112: 145 Some netgraph string length constants have been changed. This 146 change requires the netgraph kernel modules and all netgraph 147 userland components to be in sync. Especially users who require 148 netgraph to boot need to make sure to have world and kernel in 149 sync before rebooting. 150 15120031111: 152 Hyperthreading logical CPU's are no longer probed by default 153 when using the MP Table. If ACPI is being used, then logical 154 CPUs will be probed if hyperthreading is enabled in the BIOS. 155 If ACPI is not being used and hyperthreading is enabled in the 156 BIOS, logical CPUs can be enabled by building a custom kernel 157 with the option MPTABLE_FORCE_HTT enabled. 158 15920031103: 160 The i386 APIC_IO kernel option has been replaced by 161 'device apic'. The ACPI module has also been temporarily 162 disabled, so ACPI must be statically compiled into your 163 kernel using 'device acpi' if you wish to use the ACPI driver. 164 16520031031: 166 The API and ABI of struct ifnet have been changed by removing 167 the if_name and if_unit members and replacing them with 168 if_xname, if_dname, and if_dunit. All network drivers and most 169 userland programs which include net/if_var.h must be updated 170 and recompiled. __FreeBSD_version has been bumped to 501113 to 171 reflect this change. 172 17320030928: 174 Changes to the cdevsw default functions have been made to remove 175 the need to specify nullopen() and nullclose() explicitly. 176 __FreeBSD_version bumpted to 501110. 177 17820030926: 179 kiconv(3) has been added. mount_msdosfs(8), mount_ntfs(8) and 180 mount_cd9660(8) need to be in sync with kernel. 181 18220030925: 183 Configuring a system to use IPFILTER now requires that PFIL_HOOKS 184 also be explicitly configured. Previously this dependency was 185 magically handled through some cruft in net/pfil.h; but that has 186 been removed. Building a kernel with IPFILTER but not PFIL_HOOKS 187 will fail with obtuse errors in ip_fil.c. 188 18920030923: 190 Fix a bug in arplookup(), whereby a hostile party on a locally 191 attached network could exhaust kernel memory, and cause a system 192 panic, by sending a flood of spoofed ARP requests. See 193 FreeBSD-SA-03:14.arp. 194 19520030915: 196 A change to /etc/defaults/rc.conf now causes inetd to be started 197 with `-C 60' if it is not overridden in /etc/rc.conf. This 198 causes inetd to stop accepting connections from an IP address 199 that exceeds the rate of 60 connections per minute. 200 20120030829: 202 The following rc.d scripts have been removed and should be 203 deleted from your installation: atm2.sh atm3.sh devdb 204 localdaemons network1 network2 network3. Depending on when 205 you last updated world and used mergemaster(8) you may or 206 may not have problems during the rc boot sequence. The simplest 207 solution is an 'rm -rf /etc/rc.d/*' and then 'mergemaster -i'. 208 The atm2.sh atm3.sh and devdb scripts were removed some time 209 ago, so depending on when you installed -CURRENT these scripts 210 may or may not exist on your system. 211 21220030824: 213 ATAng has been committed. You need to build world as sys/ata.h 214 has changed, and userland atacontrol depends on it. 215 If you use ATA SW raids you need "device ataraid" in your 216 kernel config file, as it is no longer pulled in automatically. 217 21820030819: 219 The OFW_NEWPCI option has been turned on in the Sparc64 GENERIC kernel. 220 Among other things, this changes the device enumeration to be 221 closer to Solaris. Be aware that, this can even cause the machine 222 to not boot without manual intervention before the fstab is adjusted. 223 22420030728: 225 All current USB and Firewire quirks in da(4) have been deprecated 226 and will be removed for 5.2. If this causes failure for your 227 umass(4) devices, enable "options DA_OLD_QUIRKS" in your kernel 228 and send the output of "camcontrol inquiry da0" to scsi@freebsd.org 229 so the quirk can be re-enabled. 230 23120030724: 232 Problems with entry 20030714 have been corrected and no known issues 233 with /rescue and -j exist for host systems after this point in time. 234 23520030722: 236 FPU-less support has been removed from FreeBSD. Chances are you won't 237 notice. 386+387 support should still work after this change, but 238 it is now a minimum requirement for the i386 port that you have real 239 FPU hardware. 240 24120030714: 242 Some people are having problems with changes related to /rescue. 243 If you are building -j N, you will need to define NO_RESCUE. Others 244 will need to define it if /rescue has issues with their environment. 245 People should report those issues to current@. 246 24720030711: 248 gcc was upgraded to 3.3. You are advised to not build -DNOCLEAN 249 across this point. Further, it might be a good idea to remove 250 /usr/obj. 251 25220030610: 253 Remove deprecated locale names and transition period code 254 for them, finishing switching to the new scheme. Check your 255 LANG environment variable. 256 25720030609: 258 CCD has been changed to be a fully GEOMified class. Kernel 259 and ccdconfig(8) needs to be in sync, this is particularly 260 important to remember beforehand if your source tree is on 261 a ccd device. Consider making a copy of the old ccdconfig 262 into /boot/kernel.good or wherever you keep your backup 263 kernel. 264 26520030605: 266 There was a small window in which sed(1) was broken. If you 267 happen to have sed(1) installed during that window, which is 268 evidenced by an inability to build world with the failure 269 given below, you need to manually build and install sed(1) 270 (and only sed(1)) before doing anything else. This is a one- 271 time snafu. Typical failure mode: 272 273 In file included from /usr/src/contrib/binutils/bfd/targets.c:1092: 274 targmatch.h:7:1: null character(s) ignored 275 targmatch.h:12:1: null character(s) ignored 276 targmatch.h:16:1: null character(s) ignored 277 : 278 279 The window of "sed(1)-uction" is from Wed Jun 4 15:31:55 2003 UTC 280 to Thu Jun 5 12:10:19 2003 UTC (from rev 1.30 to rev 1.31 of 281 usr.bin/sed/process.c). 282 28320030505: 284 Kerberos 5 (Heimdal) is now built by default. Setting 285 MAKE_KERBEROS5 no longer has any effect. If you do NOT 286 want the "base" Kerberos 5, you need to set NO_KERBEROS. 287 28820030502: 289 groff has been updated. If you try to do a buildworld and 290 get an infinite loop in troff, update to May 4th or newer. If you 291 have a newer kernel than userland, you may need to set the OSRELDATE 292 to 500110 in your environment before starting a buildworld. 293 29420030501: 295 The old rc system has been removed. Please report any problems 296 to freebsd-rc@yahoogroups.com, and/or freebsd-current@freebsd.org. 297 Your personal versions of these files will not be removed, so you can 298 continue to use them. However, you should take great care when updating, 299 especially when using mergemaster, since the compatibility code that 300 utilizes these old scripts has also been removed. 301 30220030423: 303 A bug has been fixed in /dev/devctl which would cause devd 304 to hang on boot, were it not for a workaround in devd. The 305 work around in devd will be removed around 20030507. You 306 have until then to upgrade your kernel before updating 307 userland. In general, you should have a userland and 308 kernel that's in sync with each other. However, given the 309 effects of this bug (hang on boot when starting devd), some 310 allowances are made. 311 31220030329: 313 Alphas with libc from between 20030312 and 20030329 exhibit 314 floating point exceptions (FPEs), most notably in awk(1) 315 while upgrading the system through a buildworld. 316 317 So, to successfully upgrade your Alpha, you must either 318 downgrade your libc.so to a pre-20030312 version, or update 319 /usr/share/mk/bsd.cpu.mk to revision 1.26 which adds -mieee 320 to CFLAGS, then forcibly rebuild and install libc: 321 322 cd /usr/src/lib/libc && \ 323 make cleandir && make obj && \ 324 make -DNOMAN -DNOPROFILE all && \ 325 make -DNOMAN -DNOPROFILE install 326 32720030208: 328 sendmail 8.12.7 has been imported. It has one important 329 change for IPv6 users. The default submit.mc now uses 330 '[127.0.0.1]' instead of 'localhost' meaning only IPv4 is 331 used to connect to the MTA. Users on IPv6-only machines 332 will need to edit /etc/mail/submit.mc appropriately. 333 33420030128: 335 NODEVFS option has been removed and DEVFS thereby made standard. 336 This makes all references to MAKEDEV obsolete, and they should 337 be removed when convenient. 338 33920030126: 340 The name of the device for the ofw console has changed, sparc64 users 341 must run mergemaster to update their installed /etc/ttys. 342 34320030125: 344 The scheduler framework has grown a second scheduler and consequently 345 you must specify one and only one scheduler in your kernel config. 346 The cvs config files have been updated to use the old scheduler 347 which may be selected via 'options SCHED_4BSD'. If you would like 348 to try the new, much more experimental, scheduler please try 349 'options SCHED_ULE' and contribute to the arch@ discussion. 350 35120030115: 352 A new version of the wi driver has been imported into the tree. 353 One now must have device wlan in the config file for it to operate 354 properly. 355 356 In addition, there have been some changes to how wi devices are 357 configured for point to point links to bring it more in line 358 with the former way of doing things, as well as compatibility 359 with NetBSD. 360 36120021222: 362 For a period after the GCC 3.2.1 import (from 12/04 to 12/22), GCC 363 used an incompatible form of ABI for returning structures and unions 364 which FreeBSD's GCC maintainers were not aware of relative to previous 365 versions of FreeBSD. We have gone back to the ABI for now, and any 366 code compiled which is required to interoperate with other code (not 367 built at the same time) returning structs or unions should be 368 rebuilt. 369 37020021216: 371 A name change in /etc/netconfig has been reverted to stay 372 compatible with suns TIRPC and also with NetBSD. You need 373 to run mergemaster after make world. A new libc does still work 374 with an outdated /etc/netconfig for some time, but you'll get 375 a warning. This warning will be removed in 20030301. 376 37720021202: 378 The recent binutils upgrade marks a kernel flag day on 379 sparc64: modules built with the old binutils will not work 380 with new kernels and vice versa. Mismatches will result in 381 panics. Make sure your kernel and modules are in sync. 382 38320021029: 384 The value of IPPROTO_DIVERT has changed. Make sure to keep 385 your kernel, netstat, natd and any third-party DIVERT 386 consumers in sync. 387 38820021024: 389 Old, compatibility slices have been removed in GEOM kernels. 390 This means that you will have to update your /etc/fstab to 391 not use disk devices of the form /dev/ad0a. Instead, you 392 now must specify /dev/ad0s1a, or whatever slice your FreeBSD 393 partition really is on. The old device names have gone 394 away, so if you use them anywhere else, you must also adjust 395 those uses. (This doesn't affect the disks formatted in 396 the ``dangerously-dedicated'' mode.) 397 39820021023: 399 Alphas with kernels from between 20020830 and 20021023 and/or 400 rtld (ld-elf.so.1) older than 20021023 may experience problems 401 with groff while doing a buildworld (kernel: "out of memory", 402 fixed in rev 1.129 of kern/imgact_elf.c; rtld: "too few PT_LOAD 403 segments", fixed in rev 1.8 of libexec/rtld-elf/map_object.c). 404 405 So, to successfully upgrade your Alpha, you must either 406 upgrade your kernel and rtld first (which might be a bit 407 tricky), or avoid running the bootstrapped groff during the 408 "transitional" buildworld. To avoid running groff during the 409 transitional upgrade run make buildworld with -DNOMAN, 410 -DNO_SHAREDOCS, and -DNO_LPR. 411 41220020831: 413 gcc has been upgraded to 3.2. It is not all binary compatible 414 with earlier versions of gcc for c++ programs. All c++ 415 programs and libraries need to be recompiled. 416 417 Also, if you encounter g++ issues, rm /usr/include/g++/* before 418 doing an installworld to make sure that stale files are removed. 419 42020020827: 421 Our /etc/termcap now has all the entries from the XFree86 xterm 422 almost unchanged. This means xterm now supports color by default. 423 If you used TERM=xterm-color in the past you now should use 424 TERM=xterm. (xterm-color will lead to benign warnings). 425 42620020815: 427 A "bug" in gcc(1) that was hiding warning in system headers was 428 fixed. It's probably time to add -DNO_WERROR to your make line 429 again. 430 43120020729: 432 COPY is being deprecated. The 20010530 change was reverted, as 433 it causes far more pain than was expected, and to always compare 434 before installing, please use INSTALL="install -C" again. The 435 -C option is now silently ignored when used with the -d option. 436 43720020702: 438 Problems with libc_r clients like KDE and GNOME have been resolved. 439 There are still some minor problems with some signals but the 440 system is stable enough for general use again. SMP is less so than UP 441 but each can successfully complete multiple buildworlds. 442 Libkvm needs to be recompiled due to KSE. 443 44420020701: 445 Now would be a bad time to upgrade. Something in or near the 446 KSE commit totally broke programs using libc_r like KDE and 447 GNOME. 448 44920020511: 450 The k5su utility installed as part of Kerberos 5 is no longer 451 installed with the set-user-ID bit set by default. Add 452 ENABLE_SUID_K5SU=yes to /etc/make.conf to have it installed 453 with the set-user-ID bit set. 454 45520020510: 456 Gcc 3.1 debugging format (cc -g) has changed from STABS to DWARF2. 457 Unfortunately our native GDB (at version 4.18) does not understand 458 the DWARF2 debugging format. Thus you must use `gcc -gstabs+' to 459 generated debugging information for our native GDB. 460 46120020510: 462 Due to the way CVS works, it may not properly update src/contrib/gcc 463 to the 3.1 sources. The easiest fix is to `rm -rf' src/contrib/gcc 464 and then do a cvs update. 465 46620020421: 467 When exec'ing set[ug]id executables, the kernel now ensures that the 468 stdio file descriptors (0..2) are open. See FreeBSD-SA-02:23.stdio. 469 47020020404: 471 New sendmail startup scripts have been installed to make it 472 easier to use alternative MTAs with FreeBSD. Setting the rc.conf 473 variable sendmail_enable to "NO" no longer prevents any sendmail 474 daemons from starting. Instead, either set sendmail_enable to 475 "NONE" or change mta_start_script to a script for starting 476 an alternative MTA. Setting mta_start_script to "" will 477 also prevent any MTA from being started at boot. 478 47920020403: 480 UCONSOLE is no longer a valid kernel option. 481 48220020315: 483 FreeBSD 5.0 DP-1 was basically branched today. 484 48520020225: 486 Warnings are now errors in the kernel. Unless you are a developer, 487 you should add -DNO_WERROR to your make line. 488 48920020217: 490 sendmail 8.12.2 has been imported. The sendmail binary is no 491 longer a set-user-ID root binary and the infrastructure to support 492 command line mail submission has changed. Be sure to run 493 mergemaster (especially for updating /etc/rc, /etc/defaults/rc.conf, 494 and /etc/mail) and read /etc/mail/README for more details. 495 496 Due to the import of sendmail 8.12.2, a new user and group are 497 required in order for sendmail to run as a set-group-ID 498 binary. A 'make installworld' will use the new user and group 499 to set the owner and group of /var/spool/clientmqueue and will 500 fail if the new user and group do not exist. The 'smmsp' user 501 and group must be merged from src/etc/group and 502 src/etc/master.passwd before using 'make installworld'. 503 'mergemaster -p' will do this. You may need to install 504 mergemaster before this will work if you are updating from a 505 very old version of current. The updating recipe has changed 506 as of this date. 507 50820020112: 509 The preferred configuration method for PAM is now /etc/pam.d/ 510 rather than /etc/pam.conf. If you have an unmodified 511 pam.conf, just delete it after your next mergemaster run. If 512 you have local modifications, you can use 513 /usr/src/etc/pam.d/convert.pl to incorporate them into your 514 /etc/pam.d. 515 516 Please see the following url for more details: 517http://www.freebsd.org/cgi/mid.cgi?db=mid&id=<xzp6667fyoa.fsf@flood.ping.uio.no> 51820011229: 519 If anyone here is already using the new rc.conf(5) variable 520 networkfs_types, please note that it has changed 521http://www.freebsd.org/cgi/mid.cgi?db=mid&id=<9744.1009655556@axl.seasidesoftware.co.za> 522 52320011220: 524 sys/i4b/driver/i4b_ispppsubr.c has been retired. This file 525 started out its life in the ISDN4BSD project as an offspring 526 from sys/net/if_spppsubr.c, which eventually got a life of its 527 own. All the accumulated features and bugfixes of the i4b 528 version have now been merged back into the base system's 529 version now. The only user-visible change resulting from this 530 is that i4b's sppp(4) interfaces are to be managed with 531 spppcontrol(8) again, since ispppcontrol(8) has been retired 532 as well. (There has never been rc file support for 533 ispppcontrol in -current, but only in -stable. That will be 534 reverted by the time the changes are MFCed.) 535 53620011215: 537 The fdc(4) driver has been updated and now automatically 538 recognizes media in `standard' formats (like 1440 KB and 539 720 KB for a 3.5" high-density drive) when accessing the 540 default device node (e. g. /dev/fd0). The old variety of 541 floppy device nodes /dev/fd*.* is no longer present by 542 default, devices can be created (in DEVFS) on demand. They 543 will need to be customized then for `odd' densities using 544 fdcontrol(8). 545 54620011209: 547 The bugs in procfs' debugging support code have been fixed, 548 and truss(1) now works again. 549 55020011207: 551 Daily security checks have been split out to use the periodic(8) 552 scripts. Some change in configuration may be necessary. Please 553 see 554http://www.freebsd.org/cgi/mid.cgi?db=mid&id=<20011207155805.R8975@blossom.cjclark.org> 555 for details. 556 55720011204: 558 sos added VCD/SVCD support to ata driver and that needs the 559 kernel and burncd to be in sync. 560 56120011203: 562 The procfs pseudo-filesystem has now been converted to use the 563 pseudofs framework. If you have 'options PROCFS' in your 564 kernel config, you'll need to add 'options PSEUDOFS' if it's 565 not there already. 566 567 This change temporarily breaks truss(1); use ktrace(1) instead 568 until the issue has been resolved. 569 57020011202: 571 A security hole in OpenSSH involving `UseLogin yes' has been 572 patched. 573 57420011126: 575 You need to remove /usr/obj/.../usr.bin/tip before rebuilding 576 after this date. You need to do this only once. 577 57820011103: 579 Most of the awk issues have been resolved. Some rough 580 edges may be left, but for the most part things should be 581 back to "normal." For CURRENT's usual definition of "normal." 582 58320011030: 584 Awk has been upgraded to the one true awk from bell labs. Expect 585 choppy waves in the upgrade process. 586 58720011030: 588 The asr driver problem has been resolved. 589 59020011027: 591 Due to changes in other parts of the system, the asr driver 592 now causes the system to panic on boot. Do not use it pending 593 correction. Comment it out of any kernel config file that you 594 try to use from this date forward. 595 59620011025: 597 When crossbuilding, use TARGET=xxx where you used to use 598 MACHINE=xxx. You don't need to set TARGET_ARCH and TARGET, 599 unless you are changing both of them. To cross build pc98 on 600 an alpha, for example, you need to set TARGET=pc98 and 601 TARGET_ARCH=i386. 602 60320011001: 604 The kernel interface that burncd depends on has changed. 605 You must recompile both the kernel and userland applications 606 at the same time. 607 60820010929: 609 When crossbuilding, please set TARGET_ARCH rather than 610 MACHINE_ARCH to indicate the target. In the future, one will 611 set TARGET_MACHINE where you set MACHINE now. At the moment, 612 setting MACHINE alone for same MACHINE_ARCH machines works 613 (eg, you can build pc98 on an i386 machine and vice versa). 614 61520010927: 616 Some weird problems result from using ACPI on some machines. 617 To disable ACPI you can add 618 hint.acpi.0.disabled="1" 619 to /boot/loader.conf (or by putting set X=Y at the boot 620 loader "ok" prompt). 621 622 Alternatively, you can remove it from /boot/kernel/acpi.ko 623 or use the MODULES_OVERRIDE function in your kernel config 624 file and not list acpi in that list. 625 62620010924: 627 The buildworld has been fixed. You may need to install 628 the 4.x compatibility libraries for some old binaries 629 to work. Add COMPAT4X=true to your /etc/make.conf to 630 get them installed on every installworld, or execute the 631 following to get them installed only once: 632 cd src/lib/compat/compat4x.<arch> 633 make all install 634 You will see ``__stdoutp undefined'' until you do this. 635 63620010919: 637 There's a bug in the world build process. The cross-tools 638 are build with the NEW headers, but the OLD libc.a. This 639 leads to all kinds of problems with the new libc. A temporary 640 workaround is to add 641 CFLAGS="-O -pipe -D_OLD_STDIO" 642 before building world when upgrading from 4.x to current. This 643 can be removed afterwards. 644 645 A proper fix to the buildworld target is needed. 646 64720010918: 648 Peter has committed his new kthread nfs client/server code. 649 NFS may be unstable after this date. 650 65120010912: 652 KSE has hit the tree. Lots of things are now different in 653 the kernel. While a few problems were introduced in the 654 initial commit, most of the major ones have been found and 655 corrected. 656 65720010901: 658 In OLDCARD, CardBus bridges appear to be stable. The work 659 arounds described in the 20010604 entry are now no longer 660 necessary and will be ignored. Most insert/remove problems 661 have been rectified around this date. 662 66320010823: 664 named now runs as user bind and group bind rather than as 665 root. If named_enable is set to YES in /etc/rc.conf, ensure 666 that user bind is available in /etc/passwd (using vipw(8)) 667 and that group bind is available in /etc/group. Also make 668 sure that user or group bind has read (and not write) 669 permission for your name server configuration and that it 670 has read and write permission for your slave zone files and 671 directory. 672 673 If you wish to continue to run named as root (a less secure 674 alternative), add a line to /etc/rc.conf saying 675 676 named_flags= 677 67820010709: 679 The PAM libraries have had an API upgrade that is beyond 680 the ability of the shared library major number to handle. 681 It is manifested by PAM-using ports dumping core. The 682 solution is to rebuild those ports. 683 68420010628: 685 The kernel compile module has moved from src/sys/compile/FOO 686 to src/sys/${MACHINE}/compile/FOO. 687 68820010625: 689 The pccard modem issue from 20010613 has been corrected. 690 OLDCARD support is still a little weak in -current. slot 1 is 691 known not to work on some TI based cardbus bridges. Some 692 cardbus bridges do not properly detect insert/removal events. 693 IRQ configuration needs more safety belts. 694 69520010617: 696 Softupdates problems have been corrected. 697 69820010614: 699 Peter ripped out the linkerset support. You must, as always, 700 rerun config after you cvsup if you are using the traditional 701 kernel building methods. 702 70320010613: 704 pccard modems may not work with current after 20010604 date. Some 705 do, others result in panics. *MAKE*SURE* that you update your 706 config and /etc/rc.conf ala the 20010604 entry, or you will have 707 problems (this issue will be fixed, it just hasn't been yet). 708 70920010613: 710 SOFTUPDATES seem to be broken since the middle of May or so. Do not 711 use them in current. You can disable softupdates on all mounted 712 partitions, or remove SOFTUPDATES the kernel config file. 713 71420010612: 715 After Peter's commits to the hints code, people have been noticing 716 that certain devices are attached (or try to) twice. This is due 717 to having both static hints as well as a /boot/device.hints. To 718 work around this issue, please use only one or the other mechanism 719 until this bug is fixed. 720 721 Please note that a feature of config is that if you have config 722 file FOO and FOO.hints, it automatically adds FOO.hints to the 723 hints.c file, whether you want it to or not. 724 72520010610: 726 Locale names have changed to match other systems better. 727 72820010604: 729 pccard support for pci cards has been committed. You must change 730 your /etc/pccard.conf irq lines. It must match the irq used by 731 pcic device. Interrupt storms may result if you fail to do this. 732 Interrupt storms look a lot like a hang. 733 734 You must also install a new pccardd, otherwise you will get an 735 interrupt storm at card reset time (just after it tells you what 736 it is). 737 738 pccardd_flags="-I" is necessary for the time being. It tells pccardd 739 not to ask the kernel if the interrupt is really free or not before 740 using it. You can either change the /etc/pccard.conf irq lines to 741 match pcic, or add "-i X" to the pccardd_flags. 742 74320010530: 744 INSTALL=install -C is being deprecated. If you want to do this, 745 use COPY=-C instead. The former method will be supported for only 746 a limited time. If you see 747 748install: warning: the -d and -C options may not be specified together 749 750 in your makeworld, then you need to migrate towards using 751 COPY=-C. 752 75320010525: 754 It appears that vm is now stable enough to use again. However, 755 there may be other problems, so caution is still urged. alpha 756 definitely is in bad shape. 757 75820010521: 759 Minor repo damage has happened. This may cause problems 760 with cvsup of ports. If you get errors, please see 761 http://www.FreeBSD.org/cgi/query-pr.cgi?pr=27495 762 at the bottom for details on a workaround. The error message 763 is 764Updater failed: Cannot delete "/usr/ports/www/jakarta-tomcat/files": Directory not empty 765 76620010520: 767 Vm and/or swapping are busted on -current. Please be patient. 768 76920010519: 770 pccard has had much reorganizational work done to it over 771 the past few days. Everything should still work, but if 772 not, please contact imp@freebsd.org. 773 77420010517: 775 ata ioctl changed. Make sure to recompile both kernel and 776 userland at the same time. 777 77820010517: 779 New ncurses imported. 780 78120010512: 782 DEVFS is now opt out, not opt in. Barring major problems, this 783 will be the only way to go starting July 1. 784 78520010504: 786 OpenSSH has been updated to 2.9. Some defaults are different, 787 including RhostsRSAAuthentication, which changes from yes to no. 788 78920010502: 790 Perl breakage in 20010501 was corrected at 14:18:33 PDT. 791 79220010501: 793 Building perl was broken at 02:25:25 PDT. 794 79520010430: 796 The bug in 20010429 was corrected at 07:35:37 PDT. It is safe to 797 go back in the water. 798 79920010429: 800 A bad bug was committed at 04:48:42 PDT. Don't use kernels after 801 this date, but before the correction date. 802 80320010423: 804 old fsck and new kernel interactions appear to have been fixed. 805 80620010411: 807 fsck and the kernel were changed to handle some optimizations 808 to directory layout. This breaks backward compatibility. 809 Update only if you understand that you must not use the old 810 fsck with the new kernel ever. 811 81220010330: 813 fsck has changed the meaning of the pass column in /etc/fstab. 814 Please see the cvs commit to fsck.8 or the fsck.8 man page for 815 details. It is unclear if changes to /etc/fstab are necessary. 816 81720010319: 818 portmap had changed name to rpcbind for maximum POLA in your 819 current world. /etc/hosts.{allow,deny} needs changes. nfs and 820 other rpc based programs that rely on portmapper will not work 821 without updates to /etc/hosts.{allow,deny} and /etc/netconfig. 822 82320010315: 824 ata subsystem changes. ATA_ENABLE_ATAPI_DMA, ATA_ENABLE_WC 825 and ATA_ENABLE_TAGS are no longer kernel options. They have 826 been replaced by tunables. See ata.4 for details. 827 82820010312: 829 The fxp driver was converted to use miibus. If you compile 830 fxp into your kernel statically, you will need to add miibus. 831 83220010312: 833 The wi device now defaults to BSS (infrastructure) mode 834 instead of ad-hoc. 835 83620010310: 837 /dev/urandom should be a symbolic link to /dev/random now. 838 Users of current not using DEVFS need to run MAKEDEV std. 839 ssh might not work if you don't. 840 84120010303: 842 The ed driver has been updated. It now allows mii attachments, 843 which means that you must include the miibus in your kernel if 844 you use the ed driver. 845 84620010220: 847 The problems with libc have been corrected. It is now mostly 848 safe to go back into the water. 849 85020010211: 851 The size of FILE was changed. This breaks upgrading. If 852 you must upgrade, be prepared for pain. It also breaks almost 853 all binaries that you've compiled on -current. You are warned 854 that before upgrading would be a good time to do a level 0 855 dump of your system. No, really, I mean it this time. 856 857 To get to the new system, you'll need to use the following 858 workaround. Hopefully this can be sorted out so that we 859 don't have to move this to the updating section. 860 861 To get around the installworld problem, do: 862 # cd /usr/src/usr.bin/sed 863 # make install 864 # cd /usr/src 865 # make installworld 866 If that doesn't work, then try: 867 # make -k installworld 868 # make installworld 869 87020010207: 871 DEVFS is now the default. If you use vinum, make sure that you 872 do not include devfs in your kernel as problems result. 873 87420010205: 875 FFS_ROOT and CD9660_ROOT have been removed or deprecated. 876 Remove them from your config. 877 87820010122: 879 ****************************** WARNING ****************************** 880 buildkernel has been changed slightly 881 ****************************** WARNING ****************************** 882 KERNCONF replaces the variable KERNEL for buildkernel. You 883 should update your scripts and make.conf accordingly. 884 88520010119: 886 config has changed to allow DEV_FOO as a replacement for NFOO. 887 This requires a new config to build correctly. 888 88920010116: 890 The kernel option I386_CPU is now mutually exclusive with the 891 other cpu types. If you have an i386 system, be sure that it 892 only had this line. Remove it for all other configurations. 893 89420010110: 895 Changes to the kernel require it and burncd be in sync. 896 89720010102: 898 Everyone who has hw.sndunit set to something in 899 /etc/sysctl.conf, it is now hw.snd.unit. 900 90120010101: 902 ex and vi were broken by some changes to sys/queue.h. If you 903 have a bad vi, you will see make buildworld fail with a core 904 dump while building termcap. You can work around this problem 905 by adding -k to your make buildworld. This will cause the 906 build to complete and install a new vi. Once that's done, you 907 can rebuild again without the -k to pick up anything that 908 might have been ignored by the -k option. 909 910 Others have suggested that you can just rebuild libc if your 911 vi/ex is dynamically linked, but I've not received any reports 912 of this working. 913 91420001228: 915 There have been some changes to libcrypt in -current. The 916 libscrypt/libdescrypt symlink silliness is gone and the installed 917 libcrypt is fully functional. Be aware of this. 918 91920001218: 920 Linksys Fast Ethernet PCCARD cards supported by the ed driver 921 now require the addition of flag 0x80000 to their config line 922 in pccard.conf(5). This flag is not optional. These Linksys 923 cards will not be recognized without it. 924 92520001205: 926 Important new FreeBSD-version stuff: PAM support has been worked 927 in, partially from the "Unix" OpenSSH version. This requires 928 adding the following in pam.conf: 929 930 sshd auth sufficient pam_skey.so 931 sshd auth required pam_unix.so try_first_pass 932 sshd session required pam_permit.so 933 93420001031: 935 cvs updated to 1.11. 936 93720001020: 938 The random device needs more entropy, so you need to make sure 939 that you've run mergemaster to get a /etc/rc which will seed 940 /dev/random. If you don't and the system hangs after ldconfig, 941 then banging on the keyboard randomly until it unhangs is one 942 workaround. 943 94420001010: 945 ****************************** WARNING ****************************** 946 Sendmail has been updated. 947 ****************************** WARNING ****************************** 948 o mail.local(8) is no longer installed as a set-user-id binary. 949 o sendmail(8) is now built with STARTTLS support unless NO_OPENSSL 950 is set. 951 o The default /etc/mail/sendmail.cf disables the SMTP EXPN and VRFY 952 commands. 953 o Now using sendmail's version of vacation(1). 954 o The sendmail cf building tools (contrib/sendmail/cf) are installed 955 in /usr/share/sendmail/cf. 956 o sendmail.cw changed to local-host-names 957 958 More details can be found at 959 http://people.freebsd.org/~imp/UPDATING/sendmail-20001010 960 96120001009: 962 The ports tree's new layout is in place. Be sure to update 963 your entire ports tree, or you will have problems. 964 96520001006: 966 The perl build procedure no longer installs miniperl, nor uses 967 the installed miniperl. It is recommended that you delete 968 /usr/bin/miniperl. 969 97020001005: 971 This weekend the ports tree will be updated to a new layout. 972 It will be in an inconsistent state until noted in the UPDATING 973 file, or with asami-san's message to the relevant mailing 974 lists. With this new layout, you'll need to update the whole 975 tree for anything to work. 976 97720000928: 978 There was a change in the passwd format. Need more information. 979 98020000916: 981 /boot/kernel/kernel.ko -> /boot/kernel/kernel change has taken 982 place. Please update boot loader (not the boot blocks) at the 983 same time as your kernel. 984 98520000914: 986 The new pmtimer device is necessary for laptops. Failure to 987 include the device will cause suspended laptops losing time 988 when they resume. Include 989 device pmtimer 990 in your config file and 991 hint.pmtimer.0.at="isa" 992 to your /boot/device.hints file. 993 99420000911: 995 The random device has been turned into a (pseudo-)device, 996 rather than an option. The supplied kernel config files have 997 been updated. You will need to do something similar in your 998 own kernel config file. 999 Remove: 1000 options RANDOMDEV 1001 Add: 1002 device random 1003 If you prefer to load the loadable module, you need to do 1004 nothing. 1005 100620000909: 1007 The random device module has been renamed from randomdev.ko to 1008 random.ko. You will need to edit your /boot/loader.conf to 1009 reflect this if you load this module at boot time. 1010 The line should read: 1011 random_load="YES" 1012 101320000907: 1014 The SMPNG commit has happened. It should work, but if it 1015 doesn't, fallback to the PRE_SMPNG CVS tag. There are likely 1016 to be a variety of minor issues. Please see 20000905 to make 1017 sure you don't have model loading problems which might at 1018 first blush appear related to SMP. 1019 102020000906: 1021 nsswitch has been imported from NetBSD. Among other things, 1022 this means that /etc/host.conf is no longer used. See 1023 nsswitch.conf(5) instead. Note that at boot time rc.network 1024 will attempt to produce a new nsswitch.conf file for you if you 1025 don't have one, and you have host.conf. 1026 102720000905: 1028 The ucred structure changed size. This breaks the interface 1029 that mountd uses. Trying to use an older mountd with a newer 1030 kernel guarantees a panic. This means that you need to use 1031 kernels newer than today only with matching mountd, but you 1032 needed to do that anyway with the boot loader changes. 1033 103420000905: 1035 The boot loader has been updated. The new default kernel is 1036 now /boot/kernel/kernel.ko. The new default module location 1037 is /boot/kernel. 1038 1039 You *MUST* upgrade your boot loader and kernel at the same time. 1040 The easiest way to do this is to do the buildworld/buildkernel/ 1041 installkernel/installworld dance. 1042 1043 Furthermore, you are urged to delete your old /modules directory 1044 before booting the new kernel, since kldload will find stale 1045 modules in that directory instead of finding them in the correct 1046 path, /boot/kernel. The most common complaint that this cures 1047 is that the linux module crashes your machine after the update. 1048 1049 if [ ! -d /boot/kernel.old ]; then 1050 mv /modules.old /boot/kernel.old 1051 chflags noschg /kernel.old 1052 mv /kernel.old /boot/kernel.old/kernel.ko 1053 chflags schg /boot/kernel.old/kernel.ko 1054 fi 1055 105620000904: 1057 A new issue with the sendmail upgrade has come to light. 1058 /etc/aliases has moved to /etc/mail/aliases. Mergemaster will 1059 incorrectly install the default aliases in /etc/mail rather than 1060 move the old one from /etc. So you'll need to manually move the 1061 file, create a symbolic link, remove the old /etc/aliases.db and 1062 run newaliases. For safety sake, you should stop sendmail 1063 while doing this and run the upgrade when locally sourced email 1064 is not likely to be generated. 1065 106620000825: 1067 /boot/device.hints is now required for installkernel to 1068 succeed. You should copy GENERIC.hints for your architecture 1069 into /boot/device.hints. If and only if you compile hints 1070 into your kernel, then this file may be empty. Please note, 1071 if you have an empty or missing /boot/device.hints file and 1072 you neglected to compile hints into your kernel, no boot 1073 messages will appear after the boot loader tries to start the 1074 kernel. 1075 107620000821: 1077 If you do NOT have ``options RANDOMDEV'' in your kernel and 1078 you DO want the random device then add randomdev_load="YES" to 1079 /boot/loader.conf. 1080 108120000812: 1082 suidperl is now always built and installed on the system, but 1083 with permissions of 511. If you have applications that use 1084 this program, you are now required to add ENABLE_SUIDPERL=true 1085 to /etc/make.conf. If you forget to do this, 1086 chmod 4511 /usr/bin/suidperl 1087 will fix this until the next build. 1088 108920000812: 1090 sendmail has been updated from 8.9.3 to 8.11.0. Some of the more 1091 visible changes that may immediately affect your configuration 1092 include: 1093 - New default file locations from src/contrib/sendmail/cf/README 1094 - newaliases limited to root and trusted users 1095 - MSA port (587) turned on by default 1096 - New queue file naming system so can't go from 8.11 -> 8.9 1097 - FEATURE(`rbl') renamed to FEATURE(`dnsbl') 1098 - FEATURE(`nullclient') is more full featured 1099 - FEATURE(`nouucp') requires an argument: `reject' or `nospecial' 1100 - mail.local FreeBSD-only -b option changed to -B 1101 - See src/contrib/sendmail/RELEASE_NOTES for more info 1102 110320000810: 1104 suidperl (aka sperl) is no longer build by default. You must 1105 specifically define BUILD_SUIDPERL to "true" for it to be build. 1106 Furthermore, we recommend that you remove /usr/bin/sperl* and 1107 /usr/bin/suidperl files from your system unless you have a 1108 specific use for it. 1109 111020000729: 1111 Networking defaults have been tightened. Anybody upgrading 1112 /etc/defaults/rc.conf needs to add the following lines to 1113 /etc/rc.conf if they want to have the same setup 1114 afterwards (unless the variables already are set, of course): 1115 # Enable network daemons for user convenience. 1116 inetd_enable="YES" 1117 portmap_enable="YES" 1118 sendmail_enable="YES" 1119 112020000728: 1121 If you have null_load="YES" in your /boot/loader.conf, you 1122 will need to change that to nullfs_load="YES". 1123 112420000728: 1125 The "installkernel" target has changed slightly. Now even if 1126 you override KERNEL e.g. 'make installkernel KERNEL=MYKERNEL' 1127 it will install the MYKERNEL file (built with the buildkernel 1128 target) as /kernel rather than /MYKERNEL. Those who have 1129 updated their /boot/loader.conf files to point to /MYKERNEL 1130 should remove that entry or perform manual rename of /kernel 1131 to /MYKERNEL. 1132 113320000711: 1134 If you use CVSUP or CTM to get CVS trees, AND you used to get 1135 the old crypto files from internat.freebsd.org AND you check 1136 out files from the CVS tree with the cvs command, please read 1137 http://people.freebsd.org/~imp/internat.txt 1138 for details on potential problems that you might have and how 1139 to get around them. 1140 1141 If you are merely a mirror, or don't answer yes to each of the 1142 clauses above, you needn't worry. 1143 114420000711: 1145 /etc/security has been updated to print the inode number of 1146 setuid programs that have changed. You will see a large spike 1147 in the number of changed programs the first time when you run 1148 mergemaster to get a new /etc/security. 1149 115020000710: 1151 /dev/random now has good entropy collection (from the keyboard 1152 and sysmouse drivers). Please ensure that either `options 1153 RANDOMDEV' is present in your kernel config file or that 1154 `randomdev_load="YES"' is in your /boot/loader.conf. If you do 1155 not have the /dev/random driver, OpenSSL (and consequently 1156 lots of crypto tools (like SSH)) will fail with strange 1157 errors. (see below, 20000624). 1158 1159 FreeBSD-current is safe again to run Crypto. 1160 116120000709: 1162 phk made the malloc default options AJ. This may slow things 1163 down and uncover other latent bugs in the code. If you need to 1164 run at full speed, you can disable this by doing the following: 1165 ln -s aj /etc/malloc.conf 1166 116720000706: 1168 libftpio's version was accidentally bumped a few days ago. This 1169 has been corrected. You may need to remove /usr/lib/libftpio.so.6 1170 before doing your next buildworld/installworld pair. It certainly 1171 won't hurt to remove it before the update procedure. It will 1172 break fetch until a new one is built, but ftp can be used in the 1173 interim if needed. 1174 117520000705: 1176 The crypto packages have changed for the cvsup. This has been done 1177 in a backward compatible way, but the old packages will go away at 1178 some point in the future. Look at /usr/share/examples/cvsup for 1179 details. 1180 118120000704: 1182 With the new sys/modules/sound/drivers/*, you will need to 1183 set SYSDIR until you do an installworld after July 7th. 1184 118520000704: 1186 rc.shutdown and rc will now call the rc.d scripts with start 1187 or stop. This may cause some harmless warnings from older 1188 rc.d scripts that haven't been updated. 1189 119020000630: 1191 The libfetch based version of fetch has gone into the tree. 1192 Minor problems may result on some of the less popular sites, 1193 which should be reported to des@freebsd.org. 1194 119520000625: 1196 From approximately this date forward, one must have the crypto 1197 system installed in order to build the system and kernel. 1198 While not technically strictly true, one should treat it as 1199 required and grab the crypto bits. If you are grabbing CVS 1200 trees, src-all and cvs-crypto should be treated as if they 1201 were required. You should check with the latest collections 1202 to make sure that these haven't changed. 1203 120420000624: 1205 Mark Murray just committed the first parts of a cleanup of 1206 /dev/zero, et al. This is also cleaning up /dev/random. 1207 The entropy is disconnected, so DO NOT USE VERSIONS OF FREEBSD 1208 -CURRENT FROM THIS POINT to 2000710 for cryptographic services 1209 until Mark can merge in the fixes to this work in progress. 1210 openssh and openssl should not be used to generate keys from this 1211 date to the completion of the work. 1212 1213 If you must operate at this reduced level of security, add ' 1214 options RANDOMDEV' to your kernel or modload the randomdev 1215 module. You may also need to copy a new MAKEDEV to /dev and 1216 recreate the random and urandom devices. 1217 121820000622: 1219 The license on the softupdates is now a standard 2 clause 1220 BSD license. You may need to remove your symbolic links 1221 that used to be required when updating. 1222 122320000621: 1224 Scott Flatman <sf@aracnet.com> sent in a decent write-up on 1225 the config file update procedure. 1226 http://people.freebsd.org/~imp/config-upd.html 1227 NOTE: LINT is gone. It has been replaced with NOTES. NOTES 1228 isn't buildable. However, you can generate a LINT file: 1229 cd /sys/<ARCH>/conf && make LINT 1230 123120000620: 1232 Binutils 2.10 have hit the tree, or will shortly. As soon 1233 as they do, the problem noted in 20000522 will be resolved and 1234 that workaround will no longer be required. 1235 123620000615: 1237 phk removed the compatibility creation of wd devices in the 1238 ad driver. If you haven't done so already, you must update 1239 your fstab, etc to use the ad devices instead of the wd 1240 devices. 1241 1242 In addition, you'll need to update your boot blocks to a 1243 more modern version, if you haven't already done so. Modern 1244 here means 4.0 release or newer (although older releases 1245 may work). 1246 124720000612: 1248 Peter took an axe to config(8). Be sure that you read his mail 1249 on the topic before even thinking about updating. You will 1250 need to create a /boot/device.hints or add a hints directive 1251 to your config file to compile them in statically. The format 1252 of the config file has changed as well. Please see GENERIC or 1253 NEWCARD for examples of the new format. 1254 1255 Indirectly, this also breaks USERCONFIG. Unless a newer entry 1256 says that it has been fixed, assume that must use the hints mechanism 1257 in the loader if you need to use a machine with very old ISA cards 1258 in it. 1259 126020000522: 1261 A new set of binutils went into the tree today. Anybody 1262 building a kernel after this point is advised that they need 1263 to rebuild their binutils (or better yet do a 1264 buildworld/installworld) before building a new kernel. 1265 1266 Due to bugs in binutils, using malloc options (eg /etc/malloc.conf 1267 or MALLOC_OPTIONS env var) J will cause ld to dump core. It 1268 is recommended that you don't set this option until the problem 1269 is resolved. 1270 127120000513: 1272 The ethernet drivers were all updated to clean up the BPF handling. 1273 127420000510: 1275 The problems with boot blocks on the alphas have been corrected. 1276 This will require some care in updating alphas. A new libstand 1277 is requires for the boot blocks to build properly. 1278 127920000503: 1280 Recompile all kld modules. Proper version dependency info 1281 is now available. 1282 128320000502: 1284 Modules have been disconnected from the buildworld tree and 1285 connected to the kernel building instead. 1286 128720000427: 1288 You may need to build gperf 1289 cd /usr/src/gnu/usr.bin/gperf && make depend all install 1290 when upgrading from 4.0 -> current. The build system now uses 1291 an option only in -current. 1292 129320000417: 1294 The method that we brand ELF binaries has changed to be more 1295 acceptable to the binutils maintainers. You will need to 1296 rebrand your ELF binaries that aren't native. One problem 1297 binary is the Linux ldconfig. After your make world, but 1298 before you reboot, you'll need to issue: 1299 brandelf -t Linux /compat/linux/sbin/ldconfig 1300 if you have Linux compatibility enabled on your machine. 1301 130220000320: 1303 If you have really bad/marginal IDE drives, you may find they 1304 don't work well. Use pio mode instead. The easiest way to 1305 cope if you have a problem combination is to add: 1306 /sbin/sysctl hw.ata.ata_dma=0 1307 to the start of /etc/rc.conf. 1308 130920000319: 1310 The ISA and PCI compatibility shims have been connected to the 1311 options COMPAT_OLDISA and COMPAT_OLDPCI. If you are using old 1312 style PCI or ISA drivers (i.e. tx, voxware, etc.) you must 1313 include the appropriate option in your kernel config. Drivers 1314 using the shims should be updated or they won't ship with 1315 5.0-RELEASE, targeted for 2001. 1316 131720000318: 1318 We've entered the traditional post release dumping party. 1319 Large kernel changes are being committed and are in the 1320 works. It is important to keep the systems' klds and kernel 1321 in sync as kernel interfaces and structures are changing. 1322 Before reporting kernel panics, make sure that all modules 1323 that you are loading are up to date. 1324 132520000315: 1326 If you are upgrading from an older version of FreeBSD, you 1327 need to update your boot blocks as well. 'disklabel -B ad0' 1328 will do the trick. This isn't critical until you remove your 1329 wd device entries in /dev, at which point your system will not 1330 boot. 1331 133220000315: 1333 4.0 RELEASE shipped. Please see the 4.0 UPDATING file for how 1334 to upgrade to 4.0 from 3.x. 1335 1336COMMON ITEMS: 1337 1338 General Notes 1339 ------------- 1340 Avoid using make -j when upgrading. From time to time in the 1341 past there have been problems using -j with buildworld and/or 1342 installworld. This is especially true when upgrading between 1343 "distant" versions (eg one that cross a major release boundary 1344 or several minor releases, or when several months have passed 1345 on the -current branch). 1346 1347 Sometimes, obscure build problems are the result of environment 1348 poisoning. This can happen because the make utility reads its 1349 environment when searching for values for global variables. 1350 To run your build attempts in an "environmental clean room", 1351 prefix all make commands with 'env -i '. See the env(1) manual 1352 page for more details. 1353 1354 To build a kernel 1355 ----------------- 1356 If you are updating from a prior version of FreeBSD (even one just 1357 a few days old), you should follow this procedure. With a 1358 /usr/obj tree with a fresh buildworld, 1359 make -DALWAYS_CHECK_MAKE buildkernel KERNCONF=YOUR_KERNEL_HERE 1360 make -DALWAYS_CHECK_MAKE installkernel KERNCONF=YOUR_KERNEL_HERE 1361 1362 To just build a kernel when you know that it won't mess you up 1363 -------------------------------------------------------------- 1364 cd src/sys/{i386,alpha}/conf 1365 config KERNEL_NAME_HERE 1366 cd ../../compile/KERNEL_NAME_HERE 1367 make depend 1368 make 1369 make install 1370 1371 If this fails, go to the "To build a kernel" section. 1372 1373 To rebuild everything and install it on the current system. 1374 ----------------------------------------------------------- 1375 # Note: sometimes if you are running current you gotta do more than 1376 # is listed here if you are upgrading from a really old current. 1377 1378 <make sure you have good level 0 dumps> 1379 <maybe fix /etc/fstab> [7] 1380 make buildworld 1381 make buildkernel KERNCONF=YOUR_KERNEL_HERE 1382 make installkernel KERNCONF=YOUR_KERNEL_HERE 1383 [1] 1384 <reboot in single user> [3] 1385 mergemaster -p [5] 1386 make installworld 1387 mergemaster [4] 1388 <reboot> 1389 1390 1391 To cross-install current onto a separate partition 1392 -------------------------------------------------- 1393 # In this approach we use a separate partition to hold 1394 # current's root, 'usr', and 'var' directories. A partition 1395 # holding "/", "/usr" and "/var" should be about 2GB in 1396 # size. 1397 1398 <make sure you have good level 0 dumps> 1399 <boot into -stable> 1400 make buildworld 1401 <maybe newfs current's root partition> 1402 <mount current's root partition on directory ${CURRENT_ROOT}> 1403 make installworld DESTDIR=${CURRENT_ROOT} 1404 make buildkernel KERNCONF=YOUR_KERNEL_HERE 1405 cp /usr/src/sys/${ARCH}/conf/GENERIC.hints \ 1406 ${CURRENT_ROOT}/boot/device.hints # as needed 1407 make installkernel KERNCONF=YOUR_KERNEL_HERE DESTDIR=${CURRENT_ROOT} 1408 cd /usr/src/etc; make distribution DESTDIR=${CURRENT_ROOT} # if newfs'd 1409 cp /etc/fstab ${CURRENT_ROOT}/etc/fstab # if newfs'd 1410 <edit ${CURRENT_ROOT}/etc/fstab to mount "/" from the correct partition> 1411 <reboot into current> 1412 <do a "native" rebuild/install as described in the previous section> 1413 <maybe install compatibility libraries from /usr/src/lib/compat> 1414 <reboot> 1415 1416 1417 To upgrade in-place from 4.x-stable to current 1418 ---------------------------------------------- 1419 # 5.x uses more space than 4.x. Also, the location of kernel 1420 # modules has changed. If you are installing 5.0 onto a 4.x 1421 # system, you'll need about 30MB of free disk space on your / 1422 # partition. If you have less than this, you may encounter difficult 1423 # to back out of problems with this procedure. If /tmp is on 1424 # the / partition, you may want to completely remove all its content 1425 # before upgrading, as this can be a common source of shortage of 1426 # space on /. 1427 1428 <make sure you have good level 0 dumps> 1429 <maybe fix /etc/fstab> [7] 1430 make buildworld [9] 1431 make buildkernel KERNCONF=YOUR_KERNEL_HERE [8] 1432 cp src/sys/${MACHINE}/conf/GENERIC.hints /boot/device.hints [2] 1433 make installkernel KERNCONF=YOUR_KERNEL_HERE 1434 cd src/sys/boot ; make install [6] 1435 [1] 1436 <reboot in single user> [3] 1437 mergemaster -p [5] 1438 rm -rf /usr/include/g++ 1439 make installworld 1440 mergemaster [4] 1441 <reboot> 1442 1443 Make sure that you've read the UPDATING file to understand the 1444 tweaks to various things you need. At this point in the life 1445 cycle of current, things change often and you are on your own 1446 to cope. The defaults can also change, so please read ALL of 1447 the UPDATING entries. 1448 1449 Also, if you are tracking -current, you must be subscribed to 1450 freebsd-current@freebsd.org. Make sure that before you update 1451 your sources that you have read and understood all the recent 1452 messages there. If in doubt, please track -stable which has 1453 much fewer pitfalls. 1454 1455 [1] If you have third party modules, such as vmware, you 1456 should disable them at this point so they don't crash your 1457 system on reboot. 1458 1459 [2] If you have legacy ISA devices, you may need to create 1460 your own device.hints to reflect your unique hardware 1461 configuration. 1462 1463 [3] From the bootblocks, boot -s, and then do 1464 fsck -p 1465 mount -u / 1466 mount -a 1467 cd /usr/src 1468 adjkerntz -i # if CMOS is wall time 1469 Also, when doing a major release upgrade, it is required that 1470 you boot into single user mode to do the installworld. 1471 For the 4.x -> 5.0 upgrade, you will also see many messages about 1472 needing to recompile your userland. These are harmless and can 1473 be ignored while you proceed to the next step. 1474 1475 [4] Note: This step is non-optional. Failure to do this step 1476 can result in a significant reduction in the functionality of the 1477 system. Attempting to do it by hand is not recommended and those 1478 that pursue this avenue should read this file carefully, as well 1479 as the archives of freebsd-current and freebsd-hackers mailing lists 1480 for potential gotchas. 1481 1482 [5] Usually this step is a noop. However, from time to time 1483 you may need to do this if you get unknown user in the following 1484 step. It never hurts to do it all the time. You may need to 1485 install a new mergemaster (cd src/usr.sbin/mergemaster && make 1486 install) after the buildworld before this step if you last updated 1487 from current before 20020224 or from -stable before 20020408. 1488 1489 [6] 4.x boot loader can be used to boot a 5.x system, however 1490 it is difficult to do that at best. If you wish to try, then 1491 you should interrupt the boot and at the ok prompt type: 1492 ok unload 1493 ok boot /boot/kernel/kernel 1494 If this fails to work, you must install a new boot loader as 1495 described here. 1496 1497 [7] Before you upgrade, please make sure that you are not using 1498 compatibility slices. These are device names of the form, on i386 1499 and other architectures that use MBR slicing, /dev/ad0a without the 1500 actual slice name. Chances are excellent that these will break. 1501 You generally must update these entries to use the post FreeBSD 1502 2.x form of /dev/ad0s1a. 1503 1504 [8] In order to have a kernel that can run the 4.x binaries 1505 needed to do an installworld, you must include the COMPAT_FREEBSD4 1506 option in your kernel. Failure to do so may leave you with a system 1507 that is hard to boot to recover. 1508 1509 [9] When checking out sources, you must include the -P flag to have 1510 cvs prune empty directories. 1511FORMAT: 1512 1513This file contains a list, in reverse chronological order, of major 1514breakages in tracking -current. Not all things will be listed here, 1515and it only starts on March 15, 2000. Updating files can found in 1516previous releases if your system is older than this. 1517 1518Copyright information: 1519 1520Copyright 1998, 2002 M. Warner Losh.
