UPDATING revision 128485
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 2020040420: 21 Due to changes in the callout ABI, kernels compiled after this 22 date may be incompatible with kernel modules compiled prior to 23 20040406. 24 2520040414: 26 The PCI bus power state stuff has been turned on. If this causes 27 problems for your system, please disable it using the tunable 28 hw.pci.do_powerstate=0. 29 3020040412: 31 The bulk of the pci problems have been fixed, although the floppy 32 drive is still broken. 33 3420040410: 35 A substantial update to the pci bus resource and power management 36 have been committed. Expect a bumpy ride for a few days until 37 the unanticipated problems have been resolved. 38 3920040409: 40 Due to changes in the the Yarrow initialization process, 41 /dev/random needs to be fed before operations requiring 42 temp files can succeed in single user mode. This includes 43 running "make installworld". /dev/random may be fed by running 44 "/etc/rc.d/initrandom start" or with 20040415 source by running 45 "/etc/rc.d/preseedrandom". 46 4720040322: 48 The debug.mpsafenet tunable controls whether the kernel Giant 49 lock is held across the lower levels of the network stack, and 50 by default is turned off. In the few days following 20040322, 51 the behavior of debug.mpsafenet will change such that this 52 tunable controls Giant over all levels of the network stack. 53 If you are currently setting debug.mpsafenet to 1, you should 54 set it back to 0 (the default) again during the change-over. 55 An additional note will be added to UPDATING when sufficient 56 locking is merged to permit this to take place. 57 5820040310: 59 The FreeBSD/sparc64 platform is changing time_t from 32-bits to 60 64-bits. This is a very major incompatible change, so people 61 using FreeBSD/sparc64 *must* read the UPDATING.64BTT file for 62 detailed instructions on how to make this upgrade. People 63 upgrading FreeBSD on other platforms can ignore this event. 64 6520040308: 66 The packet filter (pf) is now installed with the base system. Make 67 sure to run mergemaster -p before installworld to create required 68 user account ("proxy"). If you do not want to build pf with your 69 system you can use the NO_PF knob in make.conf. 70 Also note that pf requires "options PFIL_HOOKS" in the kernel. The 71 pf system consists of the following three devices: 72 device pf # required 73 device pflog # optional 74 device pfsync # optional 75 7620040303: 77 If you are having trouble with the libc_r -> libpthread transition 78 (see the 20040130 entry), place the following lines at the top of 79 /etc/libmap.conf: 80 81 libc_r.so.5 libpthread.so.1 82 libc_r.so libpthread.so 83 84 This will cause all programs and libraries linked against libc_r 85 to use libpthread instead. 86 8720040226: 88 Some sshd configuration defaults have changed: protocol version 1 89 is no longer enabled by default, and password authentication is 90 disabled by default if PAM is enabled (which it is by default). 91 OpenSSH clients should not be affected by this; other clients may 92 have to be reconfigured, upgraded or replaced. 93 9420040225: 95 The ABIs defined in <resolv.h> and <netdb.h> have been updated 96 to support improved reentrancy. Multi-threaded programs that 97 reference the "_res" or "h_errno" symbols may experience some 98 problems if they are not recompiled. Single-threaded programs 99 should remain unaffected. 100 10120040225: 102 routed has been updated in the base system from the vendor 103 sources, routed v2.27, from rhyolite.com. This change means that 104 for users who use RIP's MD5 authentication feature, FreeBSD 105 -CURRENT's routed is now incompatible with previous versions 106 of FreeBSD; however it is now compatible with implementations 107 from Sun, Cisco and other vendors. 108 10920040224: 110 The tcpcb structure has changed and makes a recompile of libkvm 111 and related userland network utilities neccessary. 112 11320040222: 114 The cdevsw structure has changed in two externally visible ways. 115 First, the sense of the D_GIANT flag has changed to D_NEEDSGIANT. 116 Second, the d_version field must be filled in with D_VERSION. 117 Drivers outside the tree will need to be updated. 118 11920040207: 120 The /etc/rc.d/ttys script has been removed. It is no longer 121 necessary since devfs has been mandatory for some time. 122 12320040130: 124 libkse has been renamed back to libpthread and is now the 125 default threads library. The gcc -pthread option has also 126 been changed to link to libpthread instead of libc_r. For 127 alpha and sparc64 machines, libkse is not renamed and links 128 are installed so that libpthread points to libc_r. Until 129 the ports system is updated to handle this change, it is 130 recommended that folks install an /etc/libmap.conf(5) that 131 maps libc_r to libpthread. If you have any binaries or 132 libraries linked to libkse, then it is also recommended 133 that you map libkse to libpthread. Anyone that is using 134 nvidia supplied drivers and libraries should use a libmap.conf 135 that maps libpthread to libc_r since their drivers/libraries 136 do not work with libpthread. 137 13820040125: 139 ULE has entered into its probationary period as the default scheduler 140 in GENERIC. For the average user, interactivity is reported to be 141 better in many cases. On SMP machines ULE will be able to make more 142 efficient use of the available parallel resources. If you are not 143 running it now, please switch over, replacing the kernel option 144 SCHED_4BSD with SCHED_ULE. 145 14620040125: 147 Move LongRun support out of identcpu.c, where it hardly 148 belongs, into its own file and make it opt-in, not mandatory, 149 depending on CPU_ENABLE_LONGRUN config(8) option. 150 15120031213: 152 src/lib/libc/gen/initgroups.c:1.8 now causes logins to fail 153 if the login process is unable to successfully set the 154 process credentials to include all groups defined for the 155 user. The current kernel limit is 16 groups; administrators 156 may wish to check that users do not have over 16 groups 157 defined, or they will be unable to log in. 158 15920031203: 160 The ACPI module has been reactivated. It is no longer required 161 to compile ACPI support into kernels statically. 162 16320031112: 164 The statfs structure has been updated with 64-bit fields to 165 allow accurate reporting of multi-terabyte filesystem 166 sizes. You should build world, then build and boot the new kernel 167 BEFORE doing a `installworld' as the new kernel will know about 168 binaries using the old statfs structure, but an old kernel will 169 not know about the new system calls that support the new statfs 170 structure. 171 Note that the backwards compatibility is only present when the 172 kernel is configured with the COMPAT_FREEBSD4 option. Since 173 even /bin/sh will not run with a new kernel without said option 174 you're pretty much dead in the water without it. Make sure you 175 have COMPAT_FREEBSD4! 176 Running an old kernel after a `make world' will cause programs 177 such as `df' that do a statfs system call to fail with a bad 178 system call. Marco Wertejuk <wertejuk@mwcis.com> also reports 179 that cfsd (ports/security/cfs) needs to be recompiled after 180 these changes are installed. 181 182 ****************************DANGER******************************* 183 184 DO NOT make installworld after the buildworld w/o building and 185 installing a new kernel FIRST. You will be unable to build a 186 new kernel otherwise on a system with new binaries and an old 187 kernel. 188 18920031112: 190 Some netgraph string length constants have been changed. This 191 change requires the netgraph kernel modules and all netgraph 192 userland components to be in sync. Especially users who require 193 netgraph to boot need to make sure to have world and kernel in 194 sync before rebooting. 195 19620031111: 197 Hyperthreading logical CPU's are no longer probed by default 198 when using the MP Table. If ACPI is being used, then logical 199 CPUs will be probed if hyperthreading is enabled in the BIOS. 200 If ACPI is not being used and hyperthreading is enabled in the 201 BIOS, logical CPUs can be enabled by building a custom kernel 202 with the option MPTABLE_FORCE_HTT enabled. 203 20420031103: 205 The i386 APIC_IO kernel option has been replaced by 206 'device apic'. The ACPI module has also been temporarily 207 disabled, so ACPI must be statically compiled into your 208 kernel using 'device acpi' if you wish to use the ACPI driver. 209 21020031031: 211 The API and ABI of struct ifnet have been changed by removing 212 the if_name and if_unit members and replacing them with 213 if_xname, if_dname, and if_dunit. All network drivers and most 214 userland programs which include net/if_var.h must be updated 215 and recompiled. __FreeBSD_version has been bumped to 501113 to 216 reflect this change. 217 21820030928: 219 Changes to the cdevsw default functions have been made to remove 220 the need to specify nullopen() and nullclose() explicitly. 221 __FreeBSD_version bumpted to 501110. 222 22320030926: 224 kiconv(3) has been added. mount_msdosfs(8), mount_ntfs(8) and 225 mount_cd9660(8) need to be in sync with kernel. 226 22720030925: 228 Configuring a system to use IPFILTER now requires that PFIL_HOOKS 229 also be explicitly configured. Previously this dependency was 230 magically handled through some cruft in net/pfil.h; but that has 231 been removed. Building a kernel with IPFILTER but not PFIL_HOOKS 232 will fail with obtuse errors in ip_fil.c. 233 23420030923: 235 Fix a bug in arplookup(), whereby a hostile party on a locally 236 attached network could exhaust kernel memory, and cause a system 237 panic, by sending a flood of spoofed ARP requests. See 238 FreeBSD-SA-03:14.arp. 239 24020030915: 241 A change to /etc/defaults/rc.conf now causes inetd to be started 242 with `-C 60' if it is not overridden in /etc/rc.conf. This 243 causes inetd to stop accepting connections from an IP address 244 that exceeds the rate of 60 connections per minute. 245 24620030829: 247 The following rc.d scripts have been removed and should be 248 deleted from your installation: atm2.sh atm3.sh devdb 249 localdaemons network1 network2 network3. Depending on when 250 you last updated world and used mergemaster(8) you may or 251 may not have problems during the rc boot sequence. The simplest 252 solution is an 'rm -rf /etc/rc.d/*' and then 'mergemaster -i'. 253 The atm2.sh atm3.sh and devdb scripts were removed some time 254 ago, so depending on when you installed -CURRENT these scripts 255 may or may not exist on your system. 256 25720030824: 258 ATAng has been committed. You need to build world as sys/ata.h 259 has changed, and userland atacontrol depends on it. 260 If you use ATA SW raids you need "device ataraid" in your 261 kernel config file, as it is no longer pulled in automatically. 262 26320030819: 264 The OFW_NEWPCI option has been turned on in the Sparc64 GENERIC kernel. 265 Among other things, this changes the device enumeration to be 266 closer to Solaris. Be aware that, this can even cause the machine 267 to not boot without manual intervention before the fstab is adjusted. 268 26920030728: 270 All current USB and Firewire quirks in da(4) have been deprecated 271 and will be removed for 5.2. If this causes failure for your 272 umass(4) devices, enable "options DA_OLD_QUIRKS" in your kernel 273 and send the output of "camcontrol inquiry da0" to scsi@freebsd.org 274 so the quirk can be re-enabled. 275 27620030724: 277 Problems with entry 20030714 have been corrected and no known issues 278 with /rescue and -j exist for host systems after this point in time. 279 28020030722: 281 FPU-less support has been removed from FreeBSD. Chances are you won't 282 notice. 386+387 support should still work after this change, but 283 it is now a minimum requirement for the i386 port that you have real 284 FPU hardware. 285 28620030714: 287 Some people are having problems with changes related to /rescue. 288 If you are building -j N, you will need to define NO_RESCUE. Others 289 will need to define it if /rescue has issues with their environment. 290 People should report those issues to current@. 291 29220030711: 293 gcc was upgraded to 3.3. You are advised to not build -DNOCLEAN 294 across this point. Further, it might be a good idea to remove 295 /usr/obj. 296 29720030610: 298 Remove deprecated locale names and transition period code 299 for them, finishing switching to the new scheme. Check your 300 LANG environment variable. 301 30220030609: 303 CCD has been changed to be a fully GEOMified class. Kernel 304 and ccdconfig(8) needs to be in sync, this is particularly 305 important to remember beforehand if your source tree is on 306 a ccd device. Consider making a copy of the old ccdconfig 307 into /boot/kernel.good or wherever you keep your backup 308 kernel. 309 31020030605: 311 There was a small window in which sed(1) was broken. If you 312 happen to have sed(1) installed during that window, which is 313 evidenced by an inability to build world with the failure 314 given below, you need to manually build and install sed(1) 315 (and only sed(1)) before doing anything else. This is a one- 316 time snafu. Typical failure mode: 317 318 In file included from /usr/src/contrib/binutils/bfd/targets.c:1092: 319 targmatch.h:7:1: null character(s) ignored 320 targmatch.h:12:1: null character(s) ignored 321 targmatch.h:16:1: null character(s) ignored 322 : 323 324 The window of "sed(1)-uction" is from Wed Jun 4 15:31:55 2003 UTC 325 to Thu Jun 5 12:10:19 2003 UTC (from rev 1.30 to rev 1.31 of 326 usr.bin/sed/process.c). 327 32820030505: 329 Kerberos 5 (Heimdal) is now built by default. Setting 330 MAKE_KERBEROS5 no longer has any effect. If you do NOT 331 want the "base" Kerberos 5, you need to set NO_KERBEROS. 332 33320030502: 334 groff has been updated. If you try to do a buildworld and 335 get an infinite loop in troff, update to May 4th or newer. If you 336 have a newer kernel than userland, you may need to set the OSRELDATE 337 to 500110 in your environment before starting a buildworld. 338 33920030501: 340 The old rc system has been removed. Please report any problems 341 to freebsd-rc@yahoogroups.com, and/or freebsd-current@freebsd.org. 342 Your personal versions of these files will not be removed, so you can 343 continue to use them. However, you should take great care when updating, 344 especially when using mergemaster, since the compatibility code that 345 utilizes these old scripts has also been removed. 346 34720030423: 348 A bug has been fixed in /dev/devctl which would cause devd 349 to hang on boot, were it not for a workaround in devd. The 350 work around in devd will be removed around 20030507. You 351 have until then to upgrade your kernel before updating 352 userland. In general, you should have a userland and 353 kernel that's in sync with each other. However, given the 354 effects of this bug (hang on boot when starting devd), some 355 allowances are made. 356 35720030329: 358 Alphas with libc from between 20030312 and 20030329 exhibit 359 floating point exceptions (FPEs), most notably in awk(1) 360 while upgrading the system through a buildworld. 361 362 So, to successfully upgrade your Alpha, you must either 363 downgrade your libc.so to a pre-20030312 version, or update 364 /usr/share/mk/bsd.cpu.mk to revision 1.26 which adds -mieee 365 to CFLAGS, then forcibly rebuild and install libc: 366 367 cd /usr/src/lib/libc && \ 368 make cleandir && make obj && \ 369 make -DNOMAN -DNOPROFILE all && \ 370 make -DNOMAN -DNOPROFILE install 371 37220030208: 373 sendmail 8.12.7 has been imported. It has one important 374 change for IPv6 users. The default submit.mc now uses 375 '[127.0.0.1]' instead of 'localhost' meaning only IPv4 is 376 used to connect to the MTA. Users on IPv6-only machines 377 will need to edit /etc/mail/submit.mc appropriately. 378 37920030128: 380 NODEVFS option has been removed and DEVFS thereby made standard. 381 This makes all references to MAKEDEV obsolete, and they should 382 be removed when convenient. 383 38420030126: 385 The name of the device for the ofw console has changed, sparc64 users 386 must run mergemaster to update their installed /etc/ttys. 387 38820030125: 389 The scheduler framework has grown a second scheduler and consequently 390 you must specify one and only one scheduler in your kernel config. 391 The cvs config files have been updated to use the old scheduler 392 which may be selected via 'options SCHED_4BSD'. If you would like 393 to try the new, much more experimental, scheduler please try 394 'options SCHED_ULE' and contribute to the arch@ discussion. 395 39620030115: 397 A new version of the wi driver has been imported into the tree. 398 One now must have device wlan in the config file for it to operate 399 properly. 400 401 In addition, there have been some changes to how wi devices are 402 configured for point to point links to bring it more in line 403 with the former way of doing things, as well as compatibility 404 with NetBSD. 405 40620021222: 407 For a period after the GCC 3.2.1 import (from 12/04 to 12/22), GCC 408 used an incompatible form of ABI for returning structures and unions 409 which FreeBSD's GCC maintainers were not aware of relative to previous 410 versions of FreeBSD. We have gone back to the ABI for now, and any 411 code compiled which is required to interoperate with other code (not 412 built at the same time) returning structs or unions should be 413 rebuilt. 414 41520021216: 416 A name change in /etc/netconfig has been reverted to stay 417 compatible with suns TIRPC and also with NetBSD. You need 418 to run mergemaster after make world. A new libc does still work 419 with an outdated /etc/netconfig for some time, but you'll get 420 a warning. This warning will be removed in 20030301. 421 42220021202: 423 The recent binutils upgrade marks a kernel flag day on 424 sparc64: modules built with the old binutils will not work 425 with new kernels and vice versa. Mismatches will result in 426 panics. Make sure your kernel and modules are in sync. 427 42820021029: 429 The value of IPPROTO_DIVERT has changed. Make sure to keep 430 your kernel, netstat, natd and any third-party DIVERT 431 consumers in sync. 432 43320021024: 434 Old, compatibility slices have been removed in GEOM kernels. 435 This means that you will have to update your /etc/fstab to 436 not use disk devices of the form /dev/ad0a. Instead, you 437 now must specify /dev/ad0s1a, or whatever slice your FreeBSD 438 partition really is on. The old device names have gone 439 away, so if you use them anywhere else, you must also adjust 440 those uses. (This doesn't affect the disks formatted in 441 the ``dangerously-dedicated'' mode.) 442 44320021023: 444 Alphas with kernels from between 20020830 and 20021023 and/or 445 rtld (ld-elf.so.1) older than 20021023 may experience problems 446 with groff while doing a buildworld (kernel: "out of memory", 447 fixed in rev 1.129 of kern/imgact_elf.c; rtld: "too few PT_LOAD 448 segments", fixed in rev 1.8 of libexec/rtld-elf/map_object.c). 449 450 So, to successfully upgrade your Alpha, you must either 451 upgrade your kernel and rtld first (which might be a bit 452 tricky), or avoid running the bootstrapped groff during the 453 "transitional" buildworld. To avoid running groff during the 454 transitional upgrade run make buildworld with -DNOMAN, 455 -DNO_SHAREDOCS, and -DNO_LPR. 456 45720020831: 458 gcc has been upgraded to 3.2. It is not all binary compatible 459 with earlier versions of gcc for c++ programs. All c++ 460 programs and libraries need to be recompiled. 461 462 Also, if you encounter g++ issues, rm /usr/include/g++/* before 463 doing an installworld to make sure that stale files are removed. 464 46520020827: 466 Our /etc/termcap now has all the entries from the XFree86 xterm 467 almost unchanged. This means xterm now supports color by default. 468 If you used TERM=xterm-color in the past you now should use 469 TERM=xterm. (xterm-color will lead to benign warnings). 470 47120020815: 472 A "bug" in gcc(1) that was hiding warning in system headers was 473 fixed. It's probably time to add -DNO_WERROR to your make line 474 again. 475 47620020729: 477 COPY is being deprecated. The 20010530 change was reverted, as 478 it causes far more pain than was expected, and to always compare 479 before installing, please use INSTALL="install -C" again. The 480 -C option is now silently ignored when used with the -d option. 481 48220020702: 483 Problems with libc_r clients like KDE and GNOME have been resolved. 484 There are still some minor problems with some signals but the 485 system is stable enough for general use again. SMP is less so than UP 486 but each can successfully complete multiple buildworlds. 487 Libkvm needs to be recompiled due to KSE. 488 48920020701: 490 Now would be a bad time to upgrade. Something in or near the 491 KSE commit totally broke programs using libc_r like KDE and 492 GNOME. 493 49420020511: 495 The k5su utility installed as part of Kerberos 5 is no longer 496 installed with the set-user-ID bit set by default. Add 497 ENABLE_SUID_K5SU=yes to /etc/make.conf to have it installed 498 with the set-user-ID bit set. 499 50020020510: 501 Gcc 3.1 debugging format (cc -g) has changed from STABS to DWARF2. 502 Unfortunately our native GDB (at version 4.18) does not understand 503 the DWARF2 debugging format. Thus you must use `gcc -gstabs+' to 504 generated debugging information for our native GDB. 505 50620020510: 507 Due to the way CVS works, it may not properly update src/contrib/gcc 508 to the 3.1 sources. The easiest fix is to `rm -rf' src/contrib/gcc 509 and then do a cvs update. 510 51120020421: 512 When exec'ing set[ug]id executables, the kernel now ensures that the 513 stdio file descriptors (0..2) are open. See FreeBSD-SA-02:23.stdio. 514 51520020404: 516 New sendmail startup scripts have been installed to make it 517 easier to use alternative MTAs with FreeBSD. Setting the rc.conf 518 variable sendmail_enable to "NO" no longer prevents any sendmail 519 daemons from starting. Instead, either set sendmail_enable to 520 "NONE" or change mta_start_script to a script for starting 521 an alternative MTA. Setting mta_start_script to "" will 522 also prevent any MTA from being started at boot. 523 52420020403: 525 UCONSOLE is no longer a valid kernel option. 526 52720020315: 528 FreeBSD 5.0 DP-1 was basically branched today. 529 53020020225: 531 Warnings are now errors in the kernel. Unless you are a developer, 532 you should add -DNO_WERROR to your make line. 533 53420020217: 535 sendmail 8.12.2 has been imported. The sendmail binary is no 536 longer a set-user-ID root binary and the infrastructure to support 537 command line mail submission has changed. Be sure to run 538 mergemaster (especially for updating /etc/rc, /etc/defaults/rc.conf, 539 and /etc/mail) and read /etc/mail/README for more details. 540 541 Due to the import of sendmail 8.12.2, a new user and group are 542 required in order for sendmail to run as a set-group-ID 543 binary. A 'make installworld' will use the new user and group 544 to set the owner and group of /var/spool/clientmqueue and will 545 fail if the new user and group do not exist. The 'smmsp' user 546 and group must be merged from src/etc/group and 547 src/etc/master.passwd before using 'make installworld'. 548 'mergemaster -p' will do this. You may need to install 549 mergemaster before this will work if you are updating from a 550 very old version of current. The updating recipe has changed 551 as of this date. 552 55320020112: 554 The preferred configuration method for PAM is now /etc/pam.d/ 555 rather than /etc/pam.conf. If you have an unmodified 556 pam.conf, just delete it after your next mergemaster run. If 557 you have local modifications, you can use 558 /usr/src/etc/pam.d/convert.pl to incorporate them into your 559 /etc/pam.d. 560 561 Please see the following url for more details: 562http://www.freebsd.org/cgi/mid.cgi?db=mid&id=<xzp6667fyoa.fsf@flood.ping.uio.no> 56320011229: 564 If anyone here is already using the new rc.conf(5) variable 565 networkfs_types, please note that it has changed 566http://www.freebsd.org/cgi/mid.cgi?db=mid&id=<9744.1009655556@axl.seasidesoftware.co.za> 567 56820011220: 569 sys/i4b/driver/i4b_ispppsubr.c has been retired. This file 570 started out its life in the ISDN4BSD project as an offspring 571 from sys/net/if_spppsubr.c, which eventually got a life of its 572 own. All the accumulated features and bugfixes of the i4b 573 version have now been merged back into the base system's 574 version now. The only user-visible change resulting from this 575 is that i4b's sppp(4) interfaces are to be managed with 576 spppcontrol(8) again, since ispppcontrol(8) has been retired 577 as well. (There has never been rc file support for 578 ispppcontrol in -current, but only in -stable. That will be 579 reverted by the time the changes are MFCed.) 580 58120011215: 582 The fdc(4) driver has been updated and now automatically 583 recognizes media in `standard' formats (like 1440 KB and 584 720 KB for a 3.5" high-density drive) when accessing the 585 default device node (e. g. /dev/fd0). The old variety of 586 floppy device nodes /dev/fd*.* is no longer present by 587 default, devices can be created (in DEVFS) on demand. They 588 will need to be customized then for `odd' densities using 589 fdcontrol(8). 590 59120011209: 592 The bugs in procfs' debugging support code have been fixed, 593 and truss(1) now works again. 594 59520011207: 596 Daily security checks have been split out to use the periodic(8) 597 scripts. Some change in configuration may be necessary. Please 598 see 599http://www.freebsd.org/cgi/mid.cgi?db=mid&id=<20011207155805.R8975@blossom.cjclark.org> 600 for details. 601 60220011204: 603 sos added VCD/SVCD support to ata driver and that needs the 604 kernel and burncd to be in sync. 605 60620011203: 607 The procfs pseudo-filesystem has now been converted to use the 608 pseudofs framework. If you have 'options PROCFS' in your 609 kernel config, you'll need to add 'options PSEUDOFS' if it's 610 not there already. 611 612 This change temporarily breaks truss(1); use ktrace(1) instead 613 until the issue has been resolved. 614 61520011202: 616 A security hole in OpenSSH involving `UseLogin yes' has been 617 patched. 618 61920011126: 620 You need to remove /usr/obj/.../usr.bin/tip before rebuilding 621 after this date. You need to do this only once. 622 62320011103: 624 Most of the awk issues have been resolved. Some rough 625 edges may be left, but for the most part things should be 626 back to "normal." For CURRENT's usual definition of "normal." 627 62820011030: 629 Awk has been upgraded to the one true awk from bell labs. Expect 630 choppy waves in the upgrade process. 631 63220011030: 633 The asr driver problem has been resolved. 634 63520011027: 636 Due to changes in other parts of the system, the asr driver 637 now causes the system to panic on boot. Do not use it pending 638 correction. Comment it out of any kernel config file that you 639 try to use from this date forward. 640 64120011025: 642 When crossbuilding, use TARGET=xxx where you used to use 643 MACHINE=xxx. You don't need to set TARGET_ARCH and TARGET, 644 unless you are changing both of them. To cross build pc98 on 645 an alpha, for example, you need to set TARGET=pc98 and 646 TARGET_ARCH=i386. 647 64820011001: 649 The kernel interface that burncd depends on has changed. 650 You must recompile both the kernel and userland applications 651 at the same time. 652 65320010929: 654 When crossbuilding, please set TARGET_ARCH rather than 655 MACHINE_ARCH to indicate the target. In the future, one will 656 set TARGET_MACHINE where you set MACHINE now. At the moment, 657 setting MACHINE alone for same MACHINE_ARCH machines works 658 (eg, you can build pc98 on an i386 machine and vice versa). 659 66020010927: 661 Some weird problems result from using ACPI on some machines. 662 To disable ACPI you can add 663 hint.acpi.0.disabled="1" 664 to /boot/loader.conf (or by putting set X=Y at the boot 665 loader "ok" prompt). 666 667 Alternatively, you can remove it from /boot/kernel/acpi.ko 668 or use the MODULES_OVERRIDE function in your kernel config 669 file and not list acpi in that list. 670 67120010924: 672 The buildworld has been fixed. You may need to install 673 the 4.x compatibility libraries for some old binaries 674 to work. Add COMPAT4X=true to your /etc/make.conf to 675 get them installed on every installworld, or execute the 676 following to get them installed only once: 677 cd src/lib/compat/compat4x.<arch> 678 make all install 679 You will see ``__stdoutp undefined'' until you do this. 680 68120010919: 682 There's a bug in the world build process. The cross-tools 683 are build with the NEW headers, but the OLD libc.a. This 684 leads to all kinds of problems with the new libc. A temporary 685 workaround is to add 686 CFLAGS="-O -pipe -D_OLD_STDIO" 687 before building world when upgrading from 4.x to current. This 688 can be removed afterwards. 689 690 A proper fix to the buildworld target is needed. 691 69220010918: 693 Peter has committed his new kthread nfs client/server code. 694 NFS may be unstable after this date. 695 69620010912: 697 KSE has hit the tree. Lots of things are now different in 698 the kernel. While a few problems were introduced in the 699 initial commit, most of the major ones have been found and 700 corrected. 701 70220010901: 703 In OLDCARD, CardBus bridges appear to be stable. The work 704 arounds described in the 20010604 entry are now no longer 705 necessary and will be ignored. Most insert/remove problems 706 have been rectified around this date. 707 70820010823: 709 named now runs as user bind and group bind rather than as 710 root. If named_enable is set to YES in /etc/rc.conf, ensure 711 that user bind is available in /etc/passwd (using vipw(8)) 712 and that group bind is available in /etc/group. Also make 713 sure that user or group bind has read (and not write) 714 permission for your name server configuration and that it 715 has read and write permission for your slave zone files and 716 directory. 717 718 If you wish to continue to run named as root (a less secure 719 alternative), add a line to /etc/rc.conf saying 720 721 named_flags= 722 72320010709: 724 The PAM libraries have had an API upgrade that is beyond 725 the ability of the shared library major number to handle. 726 It is manifested by PAM-using ports dumping core. The 727 solution is to rebuild those ports. 728 72920010628: 730 The kernel compile module has moved from src/sys/compile/FOO 731 to src/sys/${MACHINE}/compile/FOO. 732 73320010625: 734 The pccard modem issue from 20010613 has been corrected. 735 OLDCARD support is still a little weak in -current. slot 1 is 736 known not to work on some TI based cardbus bridges. Some 737 cardbus bridges do not properly detect insert/removal events. 738 IRQ configuration needs more safety belts. 739 74020010617: 741 Softupdates problems have been corrected. 742 74320010614: 744 Peter ripped out the linkerset support. You must, as always, 745 rerun config after you cvsup if you are using the traditional 746 kernel building methods. 747 74820010613: 749 pccard modems may not work with current after 20010604 date. Some 750 do, others result in panics. *MAKE*SURE* that you update your 751 config and /etc/rc.conf ala the 20010604 entry, or you will have 752 problems (this issue will be fixed, it just hasn't been yet). 753 75420010613: 755 SOFTUPDATES seem to be broken since the middle of May or so. Do not 756 use them in current. You can disable softupdates on all mounted 757 partitions, or remove SOFTUPDATES the kernel config file. 758 75920010612: 760 After Peter's commits to the hints code, people have been noticing 761 that certain devices are attached (or try to) twice. This is due 762 to having both static hints as well as a /boot/device.hints. To 763 work around this issue, please use only one or the other mechanism 764 until this bug is fixed. 765 766 Please note that a feature of config is that if you have config 767 file FOO and FOO.hints, it automatically adds FOO.hints to the 768 hints.c file, whether you want it to or not. 769 77020010610: 771 Locale names have changed to match other systems better. 772 77320010604: 774 pccard support for pci cards has been committed. You must change 775 your /etc/pccard.conf irq lines. It must match the irq used by 776 pcic device. Interrupt storms may result if you fail to do this. 777 Interrupt storms look a lot like a hang. 778 779 You must also install a new pccardd, otherwise you will get an 780 interrupt storm at card reset time (just after it tells you what 781 it is). 782 783 pccardd_flags="-I" is necessary for the time being. It tells pccardd 784 not to ask the kernel if the interrupt is really free or not before 785 using it. You can either change the /etc/pccard.conf irq lines to 786 match pcic, or add "-i X" to the pccardd_flags. 787 78820010530: 789 INSTALL=install -C is being deprecated. If you want to do this, 790 use COPY=-C instead. The former method will be supported for only 791 a limited time. If you see 792 793install: warning: the -d and -C options may not be specified together 794 795 in your makeworld, then you need to migrate towards using 796 COPY=-C. 797 79820010525: 799 It appears that vm is now stable enough to use again. However, 800 there may be other problems, so caution is still urged. alpha 801 definitely is in bad shape. 802 80320010521: 804 Minor repo damage has happened. This may cause problems 805 with cvsup of ports. If you get errors, please see 806 http://www.FreeBSD.org/cgi/query-pr.cgi?pr=27495 807 at the bottom for details on a workaround. The error message 808 is 809Updater failed: Cannot delete "/usr/ports/www/jakarta-tomcat/files": Directory not empty 810 81120010520: 812 Vm and/or swapping are busted on -current. Please be patient. 813 81420010519: 815 pccard has had much reorganizational work done to it over 816 the past few days. Everything should still work, but if 817 not, please contact imp@freebsd.org. 818 81920010517: 820 ata ioctl changed. Make sure to recompile both kernel and 821 userland at the same time. 822 82320010517: 824 New ncurses imported. 825 82620010512: 827 DEVFS is now opt out, not opt in. Barring major problems, this 828 will be the only way to go starting July 1. 829 83020010504: 831 OpenSSH has been updated to 2.9. Some defaults are different, 832 including RhostsRSAAuthentication, which changes from yes to no. 833 83420010502: 835 Perl breakage in 20010501 was corrected at 14:18:33 PDT. 836 83720010501: 838 Building perl was broken at 02:25:25 PDT. 839 84020010430: 841 The bug in 20010429 was corrected at 07:35:37 PDT. It is safe to 842 go back in the water. 843 84420010429: 845 A bad bug was committed at 04:48:42 PDT. Don't use kernels after 846 this date, but before the correction date. 847 84820010423: 849 old fsck and new kernel interactions appear to have been fixed. 850 85120010411: 852 fsck and the kernel were changed to handle some optimizations 853 to directory layout. This breaks backward compatibility. 854 Update only if you understand that you must not use the old 855 fsck with the new kernel ever. 856 85720010330: 858 fsck has changed the meaning of the pass column in /etc/fstab. 859 Please see the cvs commit to fsck.8 or the fsck.8 man page for 860 details. It is unclear if changes to /etc/fstab are necessary. 861 86220010319: 863 portmap had changed name to rpcbind for maximum POLA in your 864 current world. /etc/hosts.{allow,deny} needs changes. nfs and 865 other rpc based programs that rely on portmapper will not work 866 without updates to /etc/hosts.{allow,deny} and /etc/netconfig. 867 86820010315: 869 ata subsystem changes. ATA_ENABLE_ATAPI_DMA, ATA_ENABLE_WC 870 and ATA_ENABLE_TAGS are no longer kernel options. They have 871 been replaced by tunables. See ata.4 for details. 872 87320010312: 874 The fxp driver was converted to use miibus. If you compile 875 fxp into your kernel statically, you will need to add miibus. 876 87720010312: 878 The wi device now defaults to BSS (infrastructure) mode 879 instead of ad-hoc. 880 88120010310: 882 /dev/urandom should be a symbolic link to /dev/random now. 883 Users of current not using DEVFS need to run MAKEDEV std. 884 ssh might not work if you don't. 885 88620010303: 887 The ed driver has been updated. It now allows mii attachments, 888 which means that you must include the miibus in your kernel if 889 you use the ed driver. 890 89120010220: 892 The problems with libc have been corrected. It is now mostly 893 safe to go back into the water. 894 89520010211: 896 The size of FILE was changed. This breaks upgrading. If 897 you must upgrade, be prepared for pain. It also breaks almost 898 all binaries that you've compiled on -current. You are warned 899 that before upgrading would be a good time to do a level 0 900 dump of your system. No, really, I mean it this time. 901 902 To get to the new system, you'll need to use the following 903 workaround. Hopefully this can be sorted out so that we 904 don't have to move this to the updating section. 905 906 To get around the installworld problem, do: 907 # cd /usr/src/usr.bin/sed 908 # make install 909 # cd /usr/src 910 # make installworld 911 If that doesn't work, then try: 912 # make -k installworld 913 # make installworld 914 91520010207: 916 DEVFS is now the default. If you use vinum, make sure that you 917 do not include devfs in your kernel as problems result. 918 91920010205: 920 FFS_ROOT and CD9660_ROOT have been removed or deprecated. 921 Remove them from your config. 922 92320010122: 924 ****************************** WARNING ****************************** 925 buildkernel has been changed slightly 926 ****************************** WARNING ****************************** 927 KERNCONF replaces the variable KERNEL for buildkernel. You 928 should update your scripts and make.conf accordingly. 929 93020010119: 931 config has changed to allow DEV_FOO as a replacement for NFOO. 932 This requires a new config to build correctly. 933 93420010116: 935 The kernel option I386_CPU is now mutually exclusive with the 936 other cpu types. If you have an i386 system, be sure that it 937 only had this line. Remove it for all other configurations. 938 93920010110: 940 Changes to the kernel require it and burncd be in sync. 941 94220010102: 943 Everyone who has hw.sndunit set to something in 944 /etc/sysctl.conf, it is now hw.snd.unit. 945 94620010101: 947 ex and vi were broken by some changes to sys/queue.h. If you 948 have a bad vi, you will see make buildworld fail with a core 949 dump while building termcap. You can work around this problem 950 by adding -k to your make buildworld. This will cause the 951 build to complete and install a new vi. Once that's done, you 952 can rebuild again without the -k to pick up anything that 953 might have been ignored by the -k option. 954 955 Others have suggested that you can just rebuild libc if your 956 vi/ex is dynamically linked, but I've not received any reports 957 of this working. 958 95920001228: 960 There have been some changes to libcrypt in -current. The 961 libscrypt/libdescrypt symlink silliness is gone and the installed 962 libcrypt is fully functional. Be aware of this. 963 96420001218: 965 Linksys Fast Ethernet PCCARD cards supported by the ed driver 966 now require the addition of flag 0x80000 to their config line 967 in pccard.conf(5). This flag is not optional. These Linksys 968 cards will not be recognized without it. 969 97020001205: 971 Important new FreeBSD-version stuff: PAM support has been worked 972 in, partially from the "Unix" OpenSSH version. This requires 973 adding the following in pam.conf: 974 975 sshd auth sufficient pam_skey.so 976 sshd auth required pam_unix.so try_first_pass 977 sshd session required pam_permit.so 978 97920001031: 980 cvs updated to 1.11. 981 98220001020: 983 The random device needs more entropy, so you need to make sure 984 that you've run mergemaster to get a /etc/rc which will seed 985 /dev/random. If you don't and the system hangs after ldconfig, 986 then banging on the keyboard randomly until it unhangs is one 987 workaround. 988 98920001010: 990 ****************************** WARNING ****************************** 991 Sendmail has been updated. 992 ****************************** WARNING ****************************** 993 o mail.local(8) is no longer installed as a set-user-id binary. 994 o sendmail(8) is now built with STARTTLS support unless NO_OPENSSL 995 is set. 996 o The default /etc/mail/sendmail.cf disables the SMTP EXPN and VRFY 997 commands. 998 o Now using sendmail's version of vacation(1). 999 o The sendmail cf building tools (contrib/sendmail/cf) are installed 1000 in /usr/share/sendmail/cf. 1001 o sendmail.cw changed to local-host-names 1002 1003 More details can be found at 1004 http://people.freebsd.org/~imp/UPDATING/sendmail-20001010 1005 100620001009: 1007 The ports tree's new layout is in place. Be sure to update 1008 your entire ports tree, or you will have problems. 1009 101020001006: 1011 The perl build procedure no longer installs miniperl, nor uses 1012 the installed miniperl. It is recommended that you delete 1013 /usr/bin/miniperl. 1014 101520001005: 1016 This weekend the ports tree will be updated to a new layout. 1017 It will be in an inconsistent state until noted in the UPDATING 1018 file, or with asami-san's message to the relevant mailing 1019 lists. With this new layout, you'll need to update the whole 1020 tree for anything to work. 1021 102220000928: 1023 There was a change in the passwd format. Need more information. 1024 102520000916: 1026 /boot/kernel/kernel.ko -> /boot/kernel/kernel change has taken 1027 place. Please update boot loader (not the boot blocks) at the 1028 same time as your kernel. 1029 103020000914: 1031 The new pmtimer device is necessary for laptops. Failure to 1032 include the device will cause suspended laptops losing time 1033 when they resume. Include 1034 device pmtimer 1035 in your config file and 1036 hint.pmtimer.0.at="isa" 1037 to your /boot/device.hints file. 1038 103920000911: 1040 The random device has been turned into a (pseudo-)device, 1041 rather than an option. The supplied kernel config files have 1042 been updated. You will need to do something similar in your 1043 own kernel config file. 1044 Remove: 1045 options RANDOMDEV 1046 Add: 1047 device random 1048 If you prefer to load the loadable module, you need to do 1049 nothing. 1050 105120000909: 1052 The random device module has been renamed from randomdev.ko to 1053 random.ko. You will need to edit your /boot/loader.conf to 1054 reflect this if you load this module at boot time. 1055 The line should read: 1056 random_load="YES" 1057 105820000907: 1059 The SMPNG commit has happened. It should work, but if it 1060 doesn't, fallback to the PRE_SMPNG CVS tag. There are likely 1061 to be a variety of minor issues. Please see 20000905 to make 1062 sure you don't have model loading problems which might at 1063 first blush appear related to SMP. 1064 106520000906: 1066 nsswitch has been imported from NetBSD. Among other things, 1067 this means that /etc/host.conf is no longer used. See 1068 nsswitch.conf(5) instead. Note that at boot time rc.network 1069 will attempt to produce a new nsswitch.conf file for you if you 1070 don't have one, and you have host.conf. 1071 107220000905: 1073 The ucred structure changed size. This breaks the interface 1074 that mountd uses. Trying to use an older mountd with a newer 1075 kernel guarantees a panic. This means that you need to use 1076 kernels newer than today only with matching mountd, but you 1077 needed to do that anyway with the boot loader changes. 1078 107920000905: 1080 The boot loader has been updated. The new default kernel is 1081 now /boot/kernel/kernel.ko. The new default module location 1082 is /boot/kernel. 1083 1084 You *MUST* upgrade your boot loader and kernel at the same time. 1085 The easiest way to do this is to do the buildworld/buildkernel/ 1086 installkernel/installworld dance. 1087 1088 Furthermore, you are urged to delete your old /modules directory 1089 before booting the new kernel, since kldload will find stale 1090 modules in that directory instead of finding them in the correct 1091 path, /boot/kernel. The most common complaint that this cures 1092 is that the linux module crashes your machine after the update. 1093 1094 if [ ! -d /boot/kernel.old ]; then 1095 mv /modules.old /boot/kernel.old 1096 chflags noschg /kernel.old 1097 mv /kernel.old /boot/kernel.old/kernel.ko 1098 chflags schg /boot/kernel.old/kernel.ko 1099 fi 1100 110120000904: 1102 A new issue with the sendmail upgrade has come to light. 1103 /etc/aliases has moved to /etc/mail/aliases. Mergemaster will 1104 incorrectly install the default aliases in /etc/mail rather than 1105 move the old one from /etc. So you'll need to manually move the 1106 file, create a symbolic link, remove the old /etc/aliases.db and 1107 run newaliases. For safety sake, you should stop sendmail 1108 while doing this and run the upgrade when locally sourced email 1109 is not likely to be generated. 1110 111120000825: 1112 /boot/device.hints is now required for installkernel to 1113 succeed. You should copy GENERIC.hints for your architecture 1114 into /boot/device.hints. If and only if you compile hints 1115 into your kernel, then this file may be empty. Please note, 1116 if you have an empty or missing /boot/device.hints file and 1117 you neglected to compile hints into your kernel, no boot 1118 messages will appear after the boot loader tries to start the 1119 kernel. 1120 112120000821: 1122 If you do NOT have ``options RANDOMDEV'' in your kernel and 1123 you DO want the random device then add randomdev_load="YES" to 1124 /boot/loader.conf. 1125 112620000812: 1127 suidperl is now always built and installed on the system, but 1128 with permissions of 511. If you have applications that use 1129 this program, you are now required to add ENABLE_SUIDPERL=true 1130 to /etc/make.conf. If you forget to do this, 1131 chmod 4511 /usr/bin/suidperl 1132 will fix this until the next build. 1133 113420000812: 1135 sendmail has been updated from 8.9.3 to 8.11.0. Some of the more 1136 visible changes that may immediately affect your configuration 1137 include: 1138 - New default file locations from src/contrib/sendmail/cf/README 1139 - newaliases limited to root and trusted users 1140 - MSA port (587) turned on by default 1141 - New queue file naming system so can't go from 8.11 -> 8.9 1142 - FEATURE(`rbl') renamed to FEATURE(`dnsbl') 1143 - FEATURE(`nullclient') is more full featured 1144 - FEATURE(`nouucp') requires an argument: `reject' or `nospecial' 1145 - mail.local FreeBSD-only -b option changed to -B 1146 - See src/contrib/sendmail/RELEASE_NOTES for more info 1147 114820000810: 1149 suidperl (aka sperl) is no longer build by default. You must 1150 specifically define BUILD_SUIDPERL to "true" for it to be build. 1151 Furthermore, we recommend that you remove /usr/bin/sperl* and 1152 /usr/bin/suidperl files from your system unless you have a 1153 specific use for it. 1154 115520000729: 1156 Networking defaults have been tightened. Anybody upgrading 1157 /etc/defaults/rc.conf needs to add the following lines to 1158 /etc/rc.conf if they want to have the same setup 1159 afterwards (unless the variables already are set, of course): 1160 # Enable network daemons for user convenience. 1161 inetd_enable="YES" 1162 portmap_enable="YES" 1163 sendmail_enable="YES" 1164 116520000728: 1166 If you have null_load="YES" in your /boot/loader.conf, you 1167 will need to change that to nullfs_load="YES". 1168 116920000728: 1170 The "installkernel" target has changed slightly. Now even if 1171 you override KERNEL e.g. 'make installkernel KERNEL=MYKERNEL' 1172 it will install the MYKERNEL file (built with the buildkernel 1173 target) as /kernel rather than /MYKERNEL. Those who have 1174 updated their /boot/loader.conf files to point to /MYKERNEL 1175 should remove that entry or perform manual rename of /kernel 1176 to /MYKERNEL. 1177 117820000711: 1179 If you use CVSUP or CTM to get CVS trees, AND you used to get 1180 the old crypto files from internat.freebsd.org AND you check 1181 out files from the CVS tree with the cvs command, please read 1182 http://people.freebsd.org/~imp/internat.txt 1183 for details on potential problems that you might have and how 1184 to get around them. 1185 1186 If you are merely a mirror, or don't answer yes to each of the 1187 clauses above, you needn't worry. 1188 118920000711: 1190 /etc/security has been updated to print the inode number of 1191 setuid programs that have changed. You will see a large spike 1192 in the number of changed programs the first time when you run 1193 mergemaster to get a new /etc/security. 1194 119520000710: 1196 /dev/random now has good entropy collection (from the keyboard 1197 and sysmouse drivers). Please ensure that either `options 1198 RANDOMDEV' is present in your kernel config file or that 1199 `randomdev_load="YES"' is in your /boot/loader.conf. If you do 1200 not have the /dev/random driver, OpenSSL (and consequently 1201 lots of crypto tools (like SSH)) will fail with strange 1202 errors. (see below, 20000624). 1203 1204 FreeBSD-current is safe again to run Crypto. 1205 120620000709: 1207 phk made the malloc default options AJ. This may slow things 1208 down and uncover other latent bugs in the code. If you need to 1209 run at full speed, you can disable this by doing the following: 1210 ln -s aj /etc/malloc.conf 1211 121220000706: 1213 libftpio's version was accidentally bumped a few days ago. This 1214 has been corrected. You may need to remove /usr/lib/libftpio.so.6 1215 before doing your next buildworld/installworld pair. It certainly 1216 won't hurt to remove it before the update procedure. It will 1217 break fetch until a new one is built, but ftp can be used in the 1218 interim if needed. 1219 122020000705: 1221 The crypto packages have changed for the cvsup. This has been done 1222 in a backward compatible way, but the old packages will go away at 1223 some point in the future. Look at /usr/share/examples/cvsup for 1224 details. 1225 122620000704: 1227 With the new sys/modules/sound/drivers/*, you will need to 1228 set SYSDIR until you do an installworld after July 7th. 1229 123020000704: 1231 rc.shutdown and rc will now call the rc.d scripts with start 1232 or stop. This may cause some harmless warnings from older 1233 rc.d scripts that haven't been updated. 1234 123520000630: 1236 The libfetch based version of fetch has gone into the tree. 1237 Minor problems may result on some of the less popular sites, 1238 which should be reported to des@freebsd.org. 1239 124020000625: 1241 From approximately this date forward, one must have the crypto 1242 system installed in order to build the system and kernel. 1243 While not technically strictly true, one should treat it as 1244 required and grab the crypto bits. If you are grabbing CVS 1245 trees, src-all and cvs-crypto should be treated as if they 1246 were required. You should check with the latest collections 1247 to make sure that these haven't changed. 1248 124920000624: 1250 Mark Murray just committed the first parts of a cleanup of 1251 /dev/zero, et al. This is also cleaning up /dev/random. 1252 The entropy is disconnected, so DO NOT USE VERSIONS OF FREEBSD 1253 -CURRENT FROM THIS POINT to 2000710 for cryptographic services 1254 until Mark can merge in the fixes to this work in progress. 1255 openssh and openssl should not be used to generate keys from this 1256 date to the completion of the work. 1257 1258 If you must operate at this reduced level of security, add ' 1259 options RANDOMDEV' to your kernel or modload the randomdev 1260 module. You may also need to copy a new MAKEDEV to /dev and 1261 recreate the random and urandom devices. 1262 126320000622: 1264 The license on the softupdates is now a standard 2 clause 1265 BSD license. You may need to remove your symbolic links 1266 that used to be required when updating. 1267 126820000621: 1269 Scott Flatman <sf@aracnet.com> sent in a decent write-up on 1270 the config file update procedure. 1271 http://people.freebsd.org/~imp/config-upd.html 1272 NOTE: LINT is gone. It has been replaced with NOTES. NOTES 1273 isn't buildable. However, you can generate a LINT file: 1274 cd /sys/<ARCH>/conf && make LINT 1275 127620000620: 1277 Binutils 2.10 have hit the tree, or will shortly. As soon 1278 as they do, the problem noted in 20000522 will be resolved and 1279 that workaround will no longer be required. 1280 128120000615: 1282 phk removed the compatibility creation of wd devices in the 1283 ad driver. If you haven't done so already, you must update 1284 your fstab, etc to use the ad devices instead of the wd 1285 devices. 1286 1287 In addition, you'll need to update your boot blocks to a 1288 more modern version, if you haven't already done so. Modern 1289 here means 4.0 release or newer (although older releases 1290 may work). 1291 129220000612: 1293 Peter took an axe to config(8). Be sure that you read his mail 1294 on the topic before even thinking about updating. You will 1295 need to create a /boot/device.hints or add a hints directive 1296 to your config file to compile them in statically. The format 1297 of the config file has changed as well. Please see GENERIC or 1298 NEWCARD for examples of the new format. 1299 1300 Indirectly, this also breaks USERCONFIG. Unless a newer entry 1301 says that it has been fixed, assume that must use the hints mechanism 1302 in the loader if you need to use a machine with very old ISA cards 1303 in it. 1304 130520000522: 1306 A new set of binutils went into the tree today. Anybody 1307 building a kernel after this point is advised that they need 1308 to rebuild their binutils (or better yet do a 1309 buildworld/installworld) before building a new kernel. 1310 1311 Due to bugs in binutils, using malloc options (eg /etc/malloc.conf 1312 or MALLOC_OPTIONS env var) J will cause ld to dump core. It 1313 is recommended that you don't set this option until the problem 1314 is resolved. 1315 131620000513: 1317 The ethernet drivers were all updated to clean up the BPF handling. 1318 131920000510: 1320 The problems with boot blocks on the alphas have been corrected. 1321 This will require some care in updating alphas. A new libstand 1322 is requires for the boot blocks to build properly. 1323 132420000503: 1325 Recompile all kld modules. Proper version dependency info 1326 is now available. 1327 132820000502: 1329 Modules have been disconnected from the buildworld tree and 1330 connected to the kernel building instead. 1331 133220000427: 1333 You may need to build gperf 1334 cd /usr/src/gnu/usr.bin/gperf && make depend all install 1335 when upgrading from 4.0 -> current. The build system now uses 1336 an option only in -current. 1337 133820000417: 1339 The method that we brand ELF binaries has changed to be more 1340 acceptable to the binutils maintainers. You will need to 1341 rebrand your ELF binaries that aren't native. One problem 1342 binary is the Linux ldconfig. After your make world, but 1343 before you reboot, you'll need to issue: 1344 brandelf -t Linux /compat/linux/sbin/ldconfig 1345 if you have Linux compatibility enabled on your machine. 1346 134720000320: 1348 If you have really bad/marginal IDE drives, you may find they 1349 don't work well. Use pio mode instead. The easiest way to 1350 cope if you have a problem combination is to add: 1351 /sbin/sysctl hw.ata.ata_dma=0 1352 to the start of /etc/rc.conf. 1353 135420000319: 1355 The ISA and PCI compatibility shims have been connected to the 1356 options COMPAT_OLDISA and COMPAT_OLDPCI. If you are using old 1357 style PCI or ISA drivers (i.e. tx, voxware, etc.) you must 1358 include the appropriate option in your kernel config. Drivers 1359 using the shims should be updated or they won't ship with 1360 5.0-RELEASE, targeted for 2001. 1361 136220000318: 1363 We've entered the traditional post release dumping party. 1364 Large kernel changes are being committed and are in the 1365 works. It is important to keep the systems' klds and kernel 1366 in sync as kernel interfaces and structures are changing. 1367 Before reporting kernel panics, make sure that all modules 1368 that you are loading are up to date. 1369 137020000315: 1371 If you are upgrading from an older version of FreeBSD, you 1372 need to update your boot blocks as well. 'disklabel -B ad0' 1373 will do the trick. This isn't critical until you remove your 1374 wd device entries in /dev, at which point your system will not 1375 boot. 1376 137720000315: 1378 4.0 RELEASE shipped. Please see the 4.0 UPDATING file for how 1379 to upgrade to 4.0 from 3.x. 1380 1381COMMON ITEMS: 1382 1383 General Notes 1384 ------------- 1385 Avoid using make -j when upgrading. From time to time in the 1386 past there have been problems using -j with buildworld and/or 1387 installworld. This is especially true when upgrading between 1388 "distant" versions (eg one that cross a major release boundary 1389 or several minor releases, or when several months have passed 1390 on the -current branch). 1391 1392 Sometimes, obscure build problems are the result of environment 1393 poisoning. This can happen because the make utility reads its 1394 environment when searching for values for global variables. 1395 To run your build attempts in an "environmental clean room", 1396 prefix all make commands with 'env -i '. See the env(1) manual 1397 page for more details. 1398 1399 To build a kernel 1400 ----------------- 1401 If you are updating from a prior version of FreeBSD (even one just 1402 a few days old), you should follow this procedure. With a 1403 /usr/obj tree with a fresh buildworld, 1404 make -DALWAYS_CHECK_MAKE buildkernel KERNCONF=YOUR_KERNEL_HERE 1405 make -DALWAYS_CHECK_MAKE installkernel KERNCONF=YOUR_KERNEL_HERE 1406 1407 To just build a kernel when you know that it won't mess you up 1408 -------------------------------------------------------------- 1409 This assumes you are already running a 5.X system. Replace 1410 ${arch} with the architecture of your machine (e.g. "i386", 1411 "alpha", "amd64", "ia64", "pc98", "sparc64", etc). 1412 1413 cd src/sys/${arch}/conf 1414 config KERNEL_NAME_HERE 1415 cd ../compile/KERNEL_NAME_HERE 1416 make depend 1417 make 1418 make install 1419 1420 If this fails, go to the "To build a kernel" section. 1421 1422 To rebuild everything and install it on the current system. 1423 ----------------------------------------------------------- 1424 # Note: sometimes if you are running current you gotta do more than 1425 # is listed here if you are upgrading from a really old current. 1426 1427 <make sure you have good level 0 dumps> 1428 <maybe fix /etc/fstab> [7] 1429 make buildworld 1430 make buildkernel KERNCONF=YOUR_KERNEL_HERE 1431 make installkernel KERNCONF=YOUR_KERNEL_HERE 1432 [1] 1433 <reboot in single user> [3] 1434 /etc/rc.d/preseedrandom [10] 1435 mergemaster -p [5] 1436 make installworld 1437 mergemaster [4] 1438 <reboot> 1439 1440 1441 To cross-install current onto a separate partition 1442 -------------------------------------------------- 1443 # In this approach we use a separate partition to hold 1444 # current's root, 'usr', and 'var' directories. A partition 1445 # holding "/", "/usr" and "/var" should be about 2GB in 1446 # size. 1447 1448 <make sure you have good level 0 dumps> 1449 <boot into -stable> 1450 make buildworld 1451 <maybe newfs current's root partition> 1452 <mount current's root partition on directory ${CURRENT_ROOT}> 1453 make installworld DESTDIR=${CURRENT_ROOT} 1454 make buildkernel KERNCONF=YOUR_KERNEL_HERE 1455 cp /usr/src/sys/${ARCH}/conf/GENERIC.hints \ 1456 ${CURRENT_ROOT}/boot/device.hints # as needed 1457 make installkernel KERNCONF=YOUR_KERNEL_HERE DESTDIR=${CURRENT_ROOT} 1458 cd /usr/src/etc; make distribution DESTDIR=${CURRENT_ROOT} # if newfs'd 1459 cp /etc/fstab ${CURRENT_ROOT}/etc/fstab # if newfs'd 1460 <edit ${CURRENT_ROOT}/etc/fstab to mount "/" from the correct partition> 1461 <reboot into current> 1462 <do a "native" rebuild/install as described in the previous section> 1463 <maybe install compatibility libraries from /usr/src/lib/compat> 1464 <reboot> 1465 1466 1467 To upgrade in-place from 4.x-stable to current 1468 ---------------------------------------------- 1469 # 5.x uses more space than 4.x. Also, the location of kernel 1470 # modules has changed. If you are installing 5.0 onto a 4.x 1471 # system, you'll need about 30MB of free disk space on your / 1472 # partition. If you have less than this, you may encounter difficult 1473 # to back out of problems with this procedure. If /tmp is on 1474 # the / partition, you may want to completely remove all its content 1475 # before upgrading, as this can be a common source of shortage of 1476 # space on /. 1477 1478 <make sure you have good level 0 dumps> 1479 <maybe fix /etc/fstab> [7] 1480 make buildworld [9] 1481 make buildkernel KERNCONF=YOUR_KERNEL_HERE [8] 1482 cp src/sys/${MACHINE}/conf/GENERIC.hints /boot/device.hints [2] 1483 make installkernel KERNCONF=YOUR_KERNEL_HERE 1484 cd src/sys/boot ; make install [6] 1485 [1] 1486 <reboot in single user> [3] 1487 /etc/rc.d/preseedrandom [10] 1488 mergemaster -p [5] 1489 rm -rf /usr/include/g++ 1490 make installworld 1491 mergemaster [4] 1492 <reboot> 1493 1494 Make sure that you've read the UPDATING file to understand the 1495 tweaks to various things you need. At this point in the life 1496 cycle of current, things change often and you are on your own 1497 to cope. The defaults can also change, so please read ALL of 1498 the UPDATING entries. 1499 1500 Also, if you are tracking -current, you must be subscribed to 1501 freebsd-current@freebsd.org. Make sure that before you update 1502 your sources that you have read and understood all the recent 1503 messages there. If in doubt, please track -stable which has 1504 much fewer pitfalls. 1505 1506 [1] If you have third party modules, such as vmware, you 1507 should disable them at this point so they don't crash your 1508 system on reboot. 1509 1510 [2] If you have legacy ISA devices, you may need to create 1511 your own device.hints to reflect your unique hardware 1512 configuration. 1513 1514 [3] From the bootblocks, boot -s, and then do 1515 fsck -p 1516 mount -u / 1517 mount -a 1518 cd /usr/src 1519 adjkerntz -i # if CMOS is wall time 1520 Also, when doing a major release upgrade, it is required that 1521 you boot into single user mode to do the installworld. 1522 For the 4.x -> 5.0 upgrade, you will also see many messages about 1523 needing to recompile your userland. These are harmless and can 1524 be ignored while you proceed to the next step. 1525 1526 [4] Note: This step is non-optional. Failure to do this step 1527 can result in a significant reduction in the functionality of the 1528 system. Attempting to do it by hand is not recommended and those 1529 that pursue this avenue should read this file carefully, as well 1530 as the archives of freebsd-current and freebsd-hackers mailing lists 1531 for potential gotchas. 1532 1533 [5] Usually this step is a noop. However, from time to time 1534 you may need to do this if you get unknown user in the following 1535 step. It never hurts to do it all the time. You may need to 1536 install a new mergemaster (cd src/usr.sbin/mergemaster && make 1537 install) after the buildworld before this step if you last updated 1538 from current before 20020224 or from -stable before 20020408. 1539 1540 [6] 4.x boot loader can be used to boot a 5.x system, however 1541 it is difficult to do that at best. If you wish to try, then 1542 you should interrupt the boot and at the ok prompt type: 1543 ok unload 1544 ok boot /boot/kernel/kernel 1545 If this fails to work, you must install a new boot loader as 1546 described here. 1547 1548 [7] Before you upgrade, please make sure that you are not using 1549 compatibility slices. These are device names of the form, on i386 1550 and other architectures that use MBR slicing, /dev/ad0a without the 1551 actual slice name. Chances are excellent that these will break. 1552 You generally must update these entries to use the post FreeBSD 1553 2.x form of /dev/ad0s1a. 1554 1555 [8] In order to have a kernel that can run the 4.x binaries 1556 needed to do an installworld, you must include the COMPAT_FREEBSD4 1557 option in your kernel. Failure to do so may leave you with a system 1558 that is hard to boot to recover. 1559 1560 [9] When checking out sources, you must include the -P flag to have 1561 cvs prune empty directories. 1562 1563 [10] In order to create temporary files, /dev/random must be 1564 initialized by feeding data into it. /etc/rc.d/preseedrandom 1565 takes care of this. 1566FORMAT: 1567 1568This file contains a list, in reverse chronological order, of major 1569breakages in tracking -current. Not all things will be listed here, 1570and it only starts on March 15, 2000. Updating files can found in 1571previous releases if your system is older than this. 1572 1573Copyright information: 1574 1575Copyright 1998, 2002 M. Warner Losh.
