These features attempt to detect 16 incorrect use of system primitives, and encourage loud failure 17 through extra sanity checking and fail stop semantics. They 18 also substantially impact system performance. If you want to 19 do performance measurement, benchmarking, and optimization, 20 you'll want to turn them off. This includes various WITNESS- 21 related kernel options, INVARIANTS, malloc debugging flags 22 in userland, and various verbose features in the kernel. Many 23 developers choose to disable these features on build machines 24 to maximize performance. 25 2620041001: 27 The following libraries had their version number bumped up: 28 /lib/libm.so.2 -> libm.so.3 29 /lib/libreadline.so.4 -> libreadline.so.5 30 /usr/lib/libhistory.so.4 -> libhistory.so.5 31 /usr/lib/libopie.so.2 -> libopie.so.3 32 /usr/lib/libpcap.so.2 -> libpcap.so.3 33 FreeBSD 4.10 versions of these libraries will be added to the 34 compat4x collection. If you expect to be able to run old 4.X 35 executables you will need to remove the old versions of these 36 libraries. However note that any 5.X executables you have built 37 will stop working once you remove those old libraries. You should 38 have all your ports/packages rebuilt before removing the old 39 libraries. 40 41 As a temporary measure, if you do not have any 4.X executables, 42 you can add the following lines to /etc/libmap.conf to force 43 5.X executables to use the new libraries: 44 45 libhistory.so.4 libhistory.so.5 46 libm.so.2 libm.so.3 47 libopie.so.2 libopie.so.3 48 libpcap.so.2 libpcap.so.3 49 libreadline.so.4 libreadline.so.5 50 5120040929: 52 The pfil API has gained an additional argument to pass an inpcb. 53 You should rebuild all pfil consuming modules: ipfw, ipfilter 54 and pf. 55 5620040928: 57 If enabled, the default is now to run named in a chroot 58 "sandbox." For users with existing configurations in 59 /etc/namedb the migration should be simple. Upgrade your 60 world as usual, then after installworld but before 61 mergemaster do the following: 62 63 /etc/rc.d/syslogd stop 64 If named is running: /etc/rc.d/named stop 65 cd /etc 66 mv namedb namedb.bak 67 mkdir -p /var/named/etc/namedb 68 cp -Rp namedb.bak/* /var/named/etc/namedb/ 69 mergemaster (with your usual options) 70 If using the generated localhost* files: 71 cd /var/named/etc/namedb 72 /bin/sh make-localhost 73 rm -f localhost-v6.rev localhost.rev 74 /etc/rc.d/syslogd start 75 /etc/rc.d/named start 76 77 If you are using a custom configuration, or if you have 78 customised the named_* variables in /etc/rc.conf[.local] 79 then you may have to adjust the instructions accordingly. 80 It is suggested that you carefully examine the new named 81 variables in /etc/defaults/rc.conf and the options in 82 /var/named/etc/namedb/named.conf to see if they might 83 now be more suitable. 84 8520040925: 86 BIND 9 has been imported into the base, and is now fully 87 functional. BIND 8 has now been removed. There are numerous 88 differences between BIND 8 and 9, and users with critical 89 named installations should read the migration documentation 90 in /usr/share/doc/bind9/misc/migration. There is also a 91 new instruction manual in /usr/share/doc/bind9/arm. 92 93 The key differences that most users will experience are in 94 how picky BIND 9 is about zone file format. If you are using 95 named as a resolving (caching) name server, you will likely 96 not have trouble. 97 98 The following files are part of the old BIND 8 installation 99 and should be removed: 100 /usr/bin/dnskeygen /usr/bin/dnsquery /usr/libexec/named-xfer 101 /usr/sbin/named.restart /usr/sbin/ndc 102 103 The following files have moved to /usr/bin, and should be 104 removed from their old locations: 105 /usr/sbin/nslookup /usr/sbin/nsupdate 106 10720040914: 108 The format of the pflogd(8) logfile "/var/log/pflog" has changed for 109 architectures that have a 64 bit long type to make it compatible to 110 the standard pcap format. In order to prevent corruption move away 111 any old logfile before using a new pflogd(8). 112 11320040906: 114 debug.witness_* has been renamed to debug.witness.*. There are 115 compatibility tunables left in for a few days. Update loader.conf 116 as necessary. 117 11820040902: 119 The ifi_epoch change has been reverted because the ABI breakage 120 was too extensive. If you are running with a kernel/userland 121 containing the initial change (20040830), you should heed the 122 warning about ifconfig incompatibility when upgrading again. 123 With this change, 5.3 and 6.0 ifconfigs and kernels are once 124 again interoperable. 125 12620040830: 127 A new variable, ifi_epoch, has been added to struct if_data 128 which is part if struct ifnet. This means all network drivers 129 and network monitoring applications need to be recompiled. 130 131 WARNING WARNING WARNING WARNING WARNING WARNING WARNING 132 133 This also breaks ifconfig compatibility. An old ifconfig will 134 not work with the new kernel and a new ifconfig will not work 135 with the old. It is strongly recommended that you make a copy 136 of your old ifconfig before installworld. If you are installing 137 remotely, you must copy over a new ifconfig before rebooting in 138 to the new kernel. 139 14020040828: 141 The default configuration for the network stack has been changed 142 such that it now runs without the Giant lock unless configured 143 otherwise. If you experience network-related instability, you 144 may wish to try setting "debug.mpsafenet=0" or compiling the 145 kernel with "options NET_WITH_GIANT". Details on the netperf 146 project may be found at: 147 148 http://www.watson.org/~robert/freebsd/netperf/ 149 150 Including the 20040828 announcement of configuration change 151 details. 152 15320040827: 154 PFIL_HOOKS are a fixed part of the network stack now and do not 155 need to be specified in the kernel configuration file anymore. 156 15720040819: 158 Netgraph changed its message format slightly to align the data 159 portion well on 64 bit machines. 160 Netgraph using utilities (e.g. ngctl, nghook, ppp, mpd, 161 pppoed, bluetooth, ATM) should be recompiled when a new kernel 162 is installed. 163 16420040817: 165 IPFW has been converted to use PFIL_HOOKS. This change is 166 transparent to userland and preserves the ipfw ABI. The ipfw 167 core packet inspection and filtering functions have not been 168 changed, only how ipfw is invoked is different. Note that 169 "option PFIL_HOOKS" is required to use IPFIREWALL compiled 170 into the kernel or as KLD. 171 17220040814: 173 The RANDOM_IP_ID option has been replaced by the sysctl 174 net.inet.ip.random_id. If you had RANDOM_IP_ID in your kernel then 175 you may want to add "net.inet.ip.random_id=1" to /etc/sysctl.conf. 176 17720040807: 178 The size of 'struct ifnet' has changed due to the addition of the 179 if_carp placeholder. All kernel modules implementing network 180 interfaces must be recompiled as a result. 181 18220040806: 183 Module loading has been fixed. Some older installations will 184 drop proper module_path initialization and modules will fail to 185 load properly. If you have a line in /boot/loader.rc that says: 186 "initialize drop", do (i386 only): 187 cp /usr/src/sys/boot/i386/loader/loader.rc /boot/loader.rc 188 chown root:wheel /boot/loader.rc 189 chmod 444 /boot/loader.rc 190 19120040802: 192 making /dev/(null|zero) into a module proved to be too unpopular, 193 so this bit has been revoked from the previous (20040801) entry. 194 19520040801: 196 The /dev/mem, /dev/io /dev/(null/zero) devices are now modules, 197 so you may wish to add them to your kernel config file. See 198 GENERIC for examples. 199 20020040728: 201 System compiler has been upgraded to GCC 3.4.2-pre. As with any major 202 compiler upgrade, there are several issues to be aware of. GCC 3.4.x 203 has broken C++ ABI compatibility with previous releases yet again 204 and users will have to rebuild all their C++ programs with the new 205 compiler. If you are getting run-time error such as 206 /libexec/ld-elf.so.1: Undefined symbol "_ZNSs20_S_empty_rep_storageE" 207 This entry does apply to you. 208 209 A new unit-at-a-time optimization mode, which is default in this 210 compiler release, is more aggressive in removing unused static 211 symbols. This is the likely cause of 'make buildworld' breakages 212 with non-default CFLAGS where optimization level is set to -O2 213 or higher. 214 215 With the upgrade of the system compiler, the kernel has been upgraded 216 to match the new system compiler. This makes it impossible to build 217 a new kernel with the old compiler. Upgrade your system via 218 make buildworld and make kernel (see below) to fix this problem. 219 22020040727: 221 The size of 'struct ifnet' has changed due to the addition of 222 the IFF_NEEDSGIANT flag (and what it implies). All kernel 223 modules implementing network interfaces must be recompiled as 224 a result. 225 22620040716: 227 The sound device drivers are renamed. `sound' is always required, 228 while `snd_*' should be configured accordingly to your hardware. 229 Refer to NOTES for the detail of the drivers. 230 23120040710: 232 __FreeBSD_version bumped to 502122. 233 23420040710: 235 The console initialization on Alpha has been reworked and is now 236 identical to other platforms. This means that the hardcoding of 237 the serial console and the debug port has been removed. As such, 238 hints are now required for the sio(4) driver to become a console 239 or debug port. The NO_SIO option has been decommissioned because 240 of this. 241 24220040710: 243 A revamp of the debugging code in the kernel with some visible 244 changes beyond just the debugging experience: 245 o The DDB option is now specific to the DDB debugger backend 246 and should not be used any more for conditional compilation 247 of debugging code for when debugging is enabled. Use the KDB 248 option for this. 249 o The WITNESS_DDB, DDB_TRACE and DDB_UNATTENDED options have 250 been renamed to WITNESS_KDB, KDB_TRACE and KDB_UNATTENDED 251 respectively. This is in line with the first bullet. 252 o The remote GDB support has been untangled from DDB and needs 253 to be enabled separately now. Use the GDB option for this. 254 o The GDB_REMOTE_CHAT option has been removed. Support for this 255 homegrown feature is discontinued. The GDB remote protocol 256 supports console output and it makes sense to use that. 257 o The DDB_NOKLDSYM option has been removed. The DDB debugger 258 now supports both direct symbol table lookups as well as KLD 259 symbol lookups through the linker. 260 26120040708: 262 Bluetooth code has been marked as non-i386 specific. 263 __FreeBSD_version has been bumped to 502121 to mark this change. 264 26520040702: 266 The native preemption has been added to the kernel scheduler. 267 There is some report that the ULE scheduler was broken in some 268 machines and we encourage users using the ULE scheduler either 269 stick with a known good kernel, or temporarily switch to the 4BSD 270 scheduler as a workaround. 271 27220040630: 273 The netgraph ABI version number has been incremented to indicate 274 an incompatible change in the ABI. Old netgraph nodes will refuse 275 to attach until recompiled. Netgraph now uses mbuf tags to move 276 metadata and this commit removes its home-grown metadata facility. 277 Nodes should just recompile, unless they use metadata, in which 278 case the changes are simple; the file ng_ksocket.c serves as an 279 example of such changes. 280 281 This also broke i4b, although the compile problem has been papered 282 over. 283 28420040630: 285 ACPI has been updated to disable known-bad BIOS revisions. A message 286 will be printed on the console indicating that ACPI has been disabled 287 automatically and that the user should use a newer BIOS, if possible. 288 If you think ACPI does work on your system and want to override 289 this (i.e., for testing), set hint.acpi.0.disabled="0" at the 290 loader prompt. 291 29220040623: 293 pf was updated to OpenBSD-stable 3.5 and pflogd(8) is privilege 294 separated now. It uses the newly created "_pflogd" user/group 295 combination. If you plan to use pflogd(8) make sure to run 296 mergemaster -p or install the "_pflogd" user and group manually. 297 29820040622: 299 Network interface cloning has been overhauled. This change will 300 require a recompile of modules using cloning and modification of 301 external ones to the new API. __FreeBSD_version has been bumped 302 to 502119 to mark this change. Additionally, users creating 303 stf(4) interfaces via "ifconfig stf" will need to update their 304 scripts as this will create an interface named "stf" instead of 305 "stf0" and ifconfig will not print "stf0" to stdout. 306 30720040621: 308 On 20040524, the /etc/rc.d/nsswitch script was modified to 309 automatically create /etc/nsswitch.conf on startup if it did 310 not already exist. Unfortunately, an error in the man page 311 was carried over to the script, resulting in incorrect 312 nsswitch settings. The simplest remedy is to remove both 313 /etc/nsswitch.conf and /etc/host.conf; they will be recreated 314 during the next reboot. 315 31620040614: 317 The return value of sema_timedwait(9) has been changed to 318 make it consistent with cv_timedwait(9). Be sure to recompile 319 the ips module and any third-party modules which call 320 sema_timedwait. 321 32220040613: 323 ALTQ is now linked to the build. This breaks ABI for struct ifnet. 324 Make sure to recompile modules and any userland that makes use of 325 sizeof(struct ifnet). In order to get the altq headers in place 326 please recompile and reinstall world. 327 32820040607: 329 Splitting kern_thread.c into 2 files (adding kern_kse.c) 330 requires that you re-run config after updating your tree. 331 33220040601: 333 The MIDI drivers have been removed. Until the new module-friendly 334 ones are merged, remove or comment out midi and seq from your 335 kernel configuration. 336 33720040423: 338 Due to a new option in ipfw (versrcreach) the ipfw(8) command 339 needs to be recompiled. Normal accept/reject rules without 340 options are not affected but those with options may break until 341 ipfw(8) is recompiled. 342 34320040420: 344 Due to changes in the callout ABI, kernels compiled after this 345 date may be incompatible with kernel modules compiled prior to 346 20040406. 347 34820040414: 349 The PCI bus power state stuff has been turned on. If this causes 350 problems for your system, please disable it using the tunable 351 hw.pci.do_powerstate=0. 352 35320040412: 354 The bulk of the pci problems have been fixed, although the floppy 355 drive is still broken. 356 35720040410: 358 A substantial update to the pci bus resource and power management 359 have been committed. Expect a bumpy ride for a few days until 360 the unanticipated problems have been resolved. 361 36220040409: 363 Due to changes in the the Yarrow initialization process, 364 /dev/random needs to be fed before operations requiring 365 temp files can succeed in single user mode. This includes 366 running "make installworld". /dev/random may be fed by running 367 "/etc/rc.d/initrandom start" or with 20040415 source by running 368 "/etc/rc.d/preseedrandom". 369 37020040322: 371 The debug.mpsafenet tunable controls whether the kernel Giant 372 lock is held across the lower levels of the network stack, and 373 by default is turned off. In the few days following 20040322, 374 the behavior of debug.mpsafenet will change such that this 375 tunable controls Giant over all levels of the network stack. 376 If you are currently setting debug.mpsafenet to 1, you should 377 set it back to 0 (the default) again during the change-over. 378 An additional note will be added to UPDATING when sufficient 379 locking is merged to permit this to take place. 380 38120040310: 382 The FreeBSD/sparc64 platform is changing time_t from 32-bits to 383 64-bits. This is a very major incompatible change, so people 384 using FreeBSD/sparc64 *must* read the UPDATING.64BTT file for 385 detailed instructions on how to make this upgrade. People 386 upgrading FreeBSD on other platforms can ignore this event. 387 38820040308: 389 The packet filter (pf) is now installed with the base system. Make 390 sure to run mergemaster -p before installworld to create required 391 user account ("proxy"). If you do not want to build pf with your 392 system you can use the NO_PF knob in make.conf. 393 Also note that pf requires "options PFIL_HOOKS" in the kernel. The 394 pf system consists of the following three devices: 395 device pf # required 396 device pflog # optional 397 device pfsync # optional 398 39920040303: 400 If you are having trouble with the libc_r -> libpthread transition 401 (see the 20040130 entry), place the following lines at the top of 402 /etc/libmap.conf: 403 404 libc_r.so.5 libpthread.so.1 405 libc_r.so libpthread.so 406 407 This will cause all programs and libraries linked against libc_r 408 to use libpthread instead. 409 41020040226: 411 Some sshd configuration defaults have changed: protocol version 1 412 is no longer enabled by default, and password authentication is 413 disabled by default if PAM is enabled (which it is by default). 414 OpenSSH clients should not be affected by this; other clients may 415 have to be reconfigured, upgraded or replaced. 416 41720040225: 418 The ABIs defined in <resolv.h> and <netdb.h> have been updated 419 to support improved reentrancy. Multi-threaded programs that 420 reference the "_res" or "h_errno" symbols may experience some 421 problems if they are not recompiled. Single-threaded programs 422 should remain unaffected. 423 42420040225: 425 routed has been updated in the base system from the vendor 426 sources, routed v2.27, from rhyolite.com. This change means that 427 for users who use RIP's MD5 authentication feature, FreeBSD 428 -CURRENT's routed is now incompatible with previous versions 429 of FreeBSD; however it is now compatible with implementations 430 from Sun, Cisco and other vendors. 431 43220040224: 433 The tcpcb structure has changed and makes a recompile of libkvm 434 and related userland network utilities necessary. 435 43620040222: 437 The cdevsw structure has changed in two externally visible ways. 438 First, the sense of the D_GIANT flag has changed to D_NEEDSGIANT. 439 Second, the d_version field must be filled in with D_VERSION. 440 Drivers outside the tree will need to be updated. 441 44220040207: 443 The /etc/rc.d/ttys script has been removed. It is no longer 444 necessary since devfs has been mandatory for some time. 445 44620040130: 447 libkse has been renamed back to libpthread and is now the 448 default threads library. The gcc -pthread option has also 449 been changed to link to libpthread instead of libc_r. For 450 alpha and sparc64 machines, libkse is not renamed and links 451 are installed so that libpthread points to libc_r. Until 452 the ports system is updated to handle this change, it is 453 recommended that folks install an /etc/libmap.conf(5) that 454 maps libc_r to libpthread. If you have any binaries or 455 libraries linked to libkse, then it is also recommended 456 that you map libkse to libpthread. Anyone that is using 457 nvidia supplied drivers and libraries should use a libmap.conf 458 that maps libpthread to libc_r since their drivers/libraries 459 do not work with libpthread. 460 46120040125: 462 ULE has entered into its probationary period as the default scheduler 463 in GENERIC. For the average user, interactivity is reported to be 464 better in many cases. On SMP machines ULE will be able to make more 465 efficient use of the available parallel resources. If you are not 466 running it now, please switch over, replacing the kernel option 467 SCHED_4BSD with SCHED_ULE. 468 46920040125: 470 Move LongRun support out of identcpu.c, where it hardly 471 belongs, into its own file and make it opt-in, not mandatory, 472 depending on CPU_ENABLE_LONGRUN config(8) option. 473 47420031213: 475 src/lib/libc/gen/initgroups.c:1.8 now causes logins to fail 476 if the login process is unable to successfully set the 477 process credentials to include all groups defined for the 478 user. The current kernel limit is 16 groups; administrators 479 may wish to check that users do not have over 16 groups 480 defined, or they will be unable to log in. 481 48220031203: 483 The ACPI module has been reactivated. It is no longer required 484 to compile ACPI support into kernels statically. 485 48620031112: 487 The statfs structure has been updated with 64-bit fields to 488 allow accurate reporting of multi-terabyte filesystem 489 sizes. You should build world, then build and boot the new kernel 490 BEFORE doing a `installworld' as the new kernel will know about 491 binaries using the old statfs structure, but an old kernel will 492 not know about the new system calls that support the new statfs 493 structure. 494 Note that the backwards compatibility is only present when the 495 kernel is configured with the COMPAT_FREEBSD4 option. Since 496 even /bin/sh will not run with a new kernel without said option 497 you're pretty much dead in the water without it. Make sure you 498 have COMPAT_FREEBSD4! 499 Running an old kernel after a `make world' will cause programs 500 such as `df' that do a statfs system call to fail with a bad 501 system call. Marco Wertejuk <wertejuk@mwcis.com> also reports 502 that cfsd (ports/security/cfs) needs to be recompiled after 503 these changes are installed. 504 505 ****************************DANGER******************************* 506 507 DO NOT make installworld after the buildworld w/o building and 508 installing a new kernel FIRST. You will be unable to build a 509 new kernel otherwise on a system with new binaries and an old 510 kernel. 511 51220031112: 513 Some netgraph string length constants have been changed. This 514 change requires the netgraph kernel modules and all netgraph 515 userland components to be in sync. Especially users who require 516 netgraph to boot need to make sure to have world and kernel in 517 sync before rebooting. 518 51920031111: 520 Hyperthreading logical CPU's are no longer probed by default 521 when using the MP Table. If ACPI is being used, then logical 522 CPUs will be probed if hyperthreading is enabled in the BIOS. 523 If ACPI is not being used and hyperthreading is enabled in the 524 BIOS, logical CPUs can be enabled by building a custom kernel 525 with the option MPTABLE_FORCE_HTT enabled. 526 52720031103: 528 The i386 APIC_IO kernel option has been replaced by 529 'device apic'. The ACPI module has also been temporarily 530 disabled, so ACPI must be statically compiled into your 531 kernel using 'device acpi' if you wish to use the ACPI driver. 532 53320031031: 534 The API and ABI of struct ifnet have been changed by removing 535 the if_name and if_unit members and replacing them with 536 if_xname, if_dname, and if_dunit. All network drivers and most 537 userland programs which include net/if_var.h must be updated 538 and recompiled. __FreeBSD_version has been bumped to 501113 to 539 reflect this change. 540 54120030928: 542 Changes to the cdevsw default functions have been made to remove 543 the need to specify nullopen() and nullclose() explicitly. 544 __FreeBSD_version bumped to 501110. 545 54620030926: 547 kiconv(3) has been added. mount_msdosfs(8), mount_ntfs(8) and 548 mount_cd9660(8) need to be in sync with kernel. 549 55020030925: 551 Configuring a system to use IPFILTER now requires that PFIL_HOOKS 552 also be explicitly configured. Previously this dependency was 553 magically handled through some cruft in net/pfil.h; but that has 554 been removed. Building a kernel with IPFILTER but not PFIL_HOOKS 555 will fail with obtuse errors in ip_fil.c. 556 55720030923: 558 Fix a bug in arplookup(), whereby a hostile party on a locally 559 attached network could exhaust kernel memory, and cause a system 560 panic, by sending a flood of spoofed ARP requests. See 561 FreeBSD-SA-03:14.arp. 562 56320030915: 564 A change to /etc/defaults/rc.conf now causes inetd to be started 565 with `-C 60' if it is not overridden in /etc/rc.conf. This 566 causes inetd to stop accepting connections from an IP address 567 that exceeds the rate of 60 connections per minute. 568 56920030829: 570 The following rc.d scripts have been removed and should be 571 deleted from your installation: atm2.sh atm3.sh devdb 572 localdaemons network1 network2 network3. Depending on when 573 you last updated world and used mergemaster(8) you may or 574 may not have problems during the rc boot sequence. The simplest 575 solution is an 'rm -rf /etc/rc.d/*' and then 'mergemaster -i'. 576 The atm2.sh atm3.sh and devdb scripts were removed some time 577 ago, so depending on when you installed -CURRENT these scripts 578 may or may not exist on your system. 579 58020030824: 581 ATAng has been committed. You need to build world as sys/ata.h 582 has changed, and userland atacontrol depends on it. 583 If you use ATA SW raids you need "device ataraid" in your 584 kernel config file, as it is no longer pulled in automatically. 585 58620030819: 587 The OFW_NEWPCI option has been turned on in the Sparc64 GENERIC kernel. 588 Among other things, this changes the device enumeration to be 589 closer to Solaris. Be aware that, this can even cause the machine 590 to not boot without manual intervention before the fstab is adjusted. 591 59220030728: 593 All current USB and Firewire quirks in da(4) have been deprecated 594 and will be removed for 5.2. If this causes failure for your 595 umass(4) devices, enable "options DA_OLD_QUIRKS" in your kernel 596 and send the output of "camcontrol inquiry da0" to scsi@freebsd.org 597 so the quirk can be re-enabled. 598 59920030724: 600 Problems with entry 20030714 have been corrected and no known issues 601 with /rescue and -j exist for host systems after this point in time. 602 60320030722: 604 FPU-less support has been removed from FreeBSD. Chances are you won't 605 notice. 386+387 support should still work after this change, but 606 it is now a minimum requirement for the i386 port that you have real 607 FPU hardware. 608 60920030714: 610 Some people are having problems with changes related to /rescue. 611 If you are building -j N, you will need to define NO_RESCUE. Others 612 will need to define it if /rescue has issues with their environment. 613 People should report those issues to current@. 614 61520030711: 616 gcc was upgraded to 3.3. You are advised to not build -DNOCLEAN 617 across this point. Further, it might be a good idea to remove 618 /usr/obj. 619 62020030610: 621 Remove deprecated locale names and transition period code 622 for them, finishing switching to the new scheme. Check your 623 LANG environment variable. 624 62520030609: 626 CCD has been changed to be a fully GEOMified class. Kernel 627 and ccdconfig(8) needs to be in sync, this is particularly 628 important to remember beforehand if your source tree is on 629 a ccd device. Consider making a copy of the old ccdconfig 630 into /boot/kernel.good or wherever you keep your backup 631 kernel. 632 63320030605: 634 There was a small window in which sed(1) was broken. If you 635 happen to have sed(1) installed during that window, which is 636 evidenced by an inability to build world with the failure 637 given below, you need to manually build and install sed(1) 638 (and only sed(1)) before doing anything else. This is a one- 639 time snafu. Typical failure mode: 640 641 In file included from /usr/src/contrib/binutils/bfd/targets.c:1092: 642 targmatch.h:7:1: null character(s) ignored 643 targmatch.h:12:1: null character(s) ignored 644 targmatch.h:16:1: null character(s) ignored 645 : 646 647 The window of "sed(1)-uction" is from Wed Jun 4 15:31:55 2003 UTC 648 to Thu Jun 5 12:10:19 2003 UTC (from rev 1.30 to rev 1.31 of 649 usr.bin/sed/process.c). 650 65120030505: 652 Kerberos 5 (Heimdal) is now built by default. Setting 653 MAKE_KERBEROS5 no longer has any effect. If you do NOT 654 want the "base" Kerberos 5, you need to set NO_KERBEROS. 655 65620030502: 657 groff has been updated. If you try to do a buildworld and 658 get an infinite loop in troff, update to May 4th or newer. If you 659 have a newer kernel than userland, you may need to set the OSRELDATE 660 to 500110 in your environment before starting a buildworld. 661 66220030501: 663 The old rc system has been removed. Please report any problems 664 to freebsd-rc@yahoogroups.com, and/or freebsd-current@freebsd.org. 665 Your personal versions of these files will not be removed, so you can 666 continue to use them. However, you should take great care when updating, 667 especially when using mergemaster, since the compatibility code that 668 utilizes these old scripts has also been removed. 669 67020030423: 671 A bug has been fixed in /dev/devctl which would cause devd 672 to hang on boot, were it not for a workaround in devd. The 673 work around in devd will be removed around 20030507. You 674 have until then to upgrade your kernel before updating 675 userland. In general, you should have a userland and 676 kernel that's in sync with each other. However, given the 677 effects of this bug (hang on boot when starting devd), some 678 allowances are made. 679 68020030329: 681 Alphas with libc from between 20030312 and 20030329 exhibit 682 floating point exceptions (FPEs), most notably in awk(1) 683 while upgrading the system through a buildworld. 684 685 So, to successfully upgrade your Alpha, you must either 686 downgrade your libc.so to a pre-20030312 version, or update 687 /usr/share/mk/bsd.cpu.mk to revision 1.26 which adds -mieee 688 to CFLAGS, then forcibly rebuild and install libc: 689 690 cd /usr/src/lib/libc && \ 691 make cleandir && make obj && \ 692 make -DNOMAN -DNOPROFILE all && \ 693 make -DNOMAN -DNOPROFILE install 694 69520030208: 696 sendmail 8.12.7 has been imported. It has one important 697 change for IPv6 users. The default submit.mc now uses 698 '[127.0.0.1]' instead of 'localhost' meaning only IPv4 is 699 used to connect to the MTA. Users on IPv6-only machines 700 will need to edit /etc/mail/submit.mc appropriately. 701 70220030128: 703 NODEVFS option has been removed and DEVFS thereby made standard. 704 This makes all references to MAKEDEV obsolete, and they should 705 be removed when convenient. 706 70720030126: 708 The name of the device for the ofw console has changed, sparc64 users 709 must run mergemaster to update their installed /etc/ttys. 710 71120030125: 712 The scheduler framework has grown a second scheduler and consequently 713 you must specify one and only one scheduler in your kernel config. 714 The cvs config files have been updated to use the old scheduler 715 which may be selected via 'options SCHED_4BSD'. If you would like 716 to try the new, much more experimental, scheduler please try 717 'options SCHED_ULE' and contribute to the arch@ discussion. 718 71920030115: 720 A new version of the wi driver has been imported into the tree. 721 One now must have device wlan in the config file for it to operate 722 properly. 723 724 In addition, there have been some changes to how wi devices are 725 configured for point to point links to bring it more in line 726 with the former way of doing things, as well as compatibility 727 with NetBSD. 728 72920021222: 730 For a period after the GCC 3.2.1 import (from 12/04 to 12/22), GCC 731 used an incompatible form of ABI for returning structures and unions 732 which FreeBSD's GCC maintainers were not aware of relative to previous 733 versions of FreeBSD. We have gone back to the ABI for now, and any 734 code compiled which is required to interoperate with other code (not 735 built at the same time) returning structs or unions should be 736 rebuilt. 737 73820021216: 739 A name change in /etc/netconfig has been reverted to stay 740 compatible with suns TIRPC and also with NetBSD. You need 741 to run mergemaster after make world. A new libc does still work 742 with an outdated /etc/netconfig for some time, but you'll get 743 a warning. This warning will be removed in 20030301. 744 74520021202: 746 The recent binutils upgrade marks a kernel flag day on 747 sparc64: modules built with the old binutils will not work 748 with new kernels and vice versa. Mismatches will result in 749 panics. Make sure your kernel and modules are in sync. 750 75120021029: 752 The value of IPPROTO_DIVERT has changed. Make sure to keep 753 your kernel, netstat, natd and any third-party DIVERT 754 consumers in sync. 755 75620021024: 757 Old, compatibility slices have been removed in GEOM kernels. 758 This means that you will have to update your /etc/fstab to 759 not use disk devices of the form /dev/ad0a. Instead, you 760 now must specify /dev/ad0s1a, or whatever slice your FreeBSD 761 partition really is on. The old device names have gone 762 away, so if you use them anywhere else, you must also adjust 763 those uses. (This doesn't affect the disks formatted in 764 the ``dangerously-dedicated'' mode.) 765 76620021023: 767 Alphas with kernels from between 20020830 and 20021023 and/or 768 rtld (ld-elf.so.1) older than 20021023 may experience problems 769 with groff while doing a buildworld (kernel: "out of memory", 770 fixed in rev 1.129 of kern/imgact_elf.c; rtld: "too few PT_LOAD 771 segments", fixed in rev 1.8 of libexec/rtld-elf/map_object.c). 772 773 So, to successfully upgrade your Alpha, you must either 774 upgrade your kernel and rtld first (which might be a bit 775 tricky), or avoid running the bootstrapped groff during the 776 "transitional" buildworld. To avoid running groff during the 777 transitional upgrade run make buildworld with -DNOMAN, 778 -DNO_SHAREDOCS, and -DNO_LPR. 779 78020020831: 781 gcc has been upgraded to 3.2. It is not all binary compatible 782 with earlier versions of gcc for c++ programs. All c++ 783 programs and libraries need to be recompiled. 784 785 Also, if you encounter g++ issues, rm /usr/include/g++/* before 786 doing an installworld to make sure that stale files are removed. 787 78820020827: 789 Our /etc/termcap now has all the entries from the XFree86 xterm 790 almost unchanged. This means xterm now supports color by default. 791 If you used TERM=xterm-color in the past you now should use 792 TERM=xterm. (xterm-color will lead to benign warnings). 793 79420020815: 795 A "bug" in gcc(1) that was hiding warning in system headers was 796 fixed. It's probably time to add -DNO_WERROR to your make line 797 again. 798 79920020729: 800 COPY is being deprecated. The 20010530 change was reverted, as 801 it causes far more pain than was expected, and to always compare 802 before installing, please use INSTALL="install -C" again. The 803 -C option is now silently ignored when used with the -d option. 804 80520020702: 806 Problems with libc_r clients like KDE and GNOME have been resolved. 807 There are still some minor problems with some signals but the 808 system is stable enough for general use again. SMP is less so than UP 809 but each can successfully complete multiple buildworlds. 810 Libkvm needs to be recompiled due to KSE. 811 81220020701: 813 Now would be a bad time to upgrade. Something in or near the 814 KSE commit totally broke programs using libc_r like KDE and 815 GNOME. 816 81720020511: 818 The k5su utility installed as part of Kerberos 5 is no longer 819 installed with the set-user-ID bit set by default. Add 820 ENABLE_SUID_K5SU=yes to /etc/make.conf to have it installed 821 with the set-user-ID bit set. 822 82320020510: 824 Gcc 3.1 debugging format (cc -g) has changed from STABS to DWARF2. 825 Unfortunately our native GDB (at version 4.18) does not understand 826 the DWARF2 debugging format. Thus you must use `gcc -gstabs+' to 827 generated debugging information for our native GDB. 828 82920020510: 830 Due to the way CVS works, it may not properly update src/contrib/gcc 831 to the 3.1 sources. The easiest fix is to `rm -rf' src/contrib/gcc 832 and then do a cvs update. 833 83420020421: 835 When exec'ing set[ug]id executables, the kernel now ensures that the 836 stdio file descriptors (0..2) are open. See FreeBSD-SA-02:23.stdio. 837 83820020404: 839 New sendmail startup scripts have been installed to make it 840 easier to use alternative MTAs with FreeBSD. Setting the rc.conf 841 variable sendmail_enable to "NO" no longer prevents any sendmail 842 daemons from starting. Instead, either set sendmail_enable to 843 "NONE" or change mta_start_script to a script for starting 844 an alternative MTA. Setting mta_start_script to "" will 845 also prevent any MTA from being started at boot. 846 84720020403: 848 UCONSOLE is no longer a valid kernel option. 849 85020020315: 851 FreeBSD 5.0 DP-1 was basically branched today. 852 85320020225: 854 Warnings are now errors in the kernel. Unless you are a developer, 855 you should add -DNO_WERROR to your make line. 856 85720020217: 858 sendmail 8.12.2 has been imported. The sendmail binary is no 859 longer a set-user-ID root binary and the infrastructure to support 860 command line mail submission has changed. Be sure to run 861 mergemaster (especially for updating /etc/rc, /etc/defaults/rc.conf, 862 and /etc/mail) and read /etc/mail/README for more details. 863 864 Due to the import of sendmail 8.12.2, a new user and group are 865 required in order for sendmail to run as a set-group-ID 866 binary. A 'make installworld' will use the new user and group 867 to set the owner and group of /var/spool/clientmqueue and will 868 fail if the new user and group do not exist. The 'smmsp' user 869 and group must be merged from src/etc/group and 870 src/etc/master.passwd before using 'make installworld'. 871 'mergemaster -p' will do this. You may need to install 872 mergemaster before this will work if you are updating from a 873 very old version of current. The updating recipe has changed 874 as of this date. 875 87620020112: 877 The preferred configuration method for PAM is now /etc/pam.d/ 878 rather than /etc/pam.conf. If you have an unmodified 879 pam.conf, just delete it after your next mergemaster run. If 880 you have local modifications, you can use 881 /usr/src/etc/pam.d/convert.pl to incorporate them into your 882 /etc/pam.d. 883 884 Please see the following url for more details: 885http://www.freebsd.org/cgi/mid.cgi?db=mid&id=<xzp6667fyoa.fsf@flood.ping.uio.no> 88620011229: 887 If anyone here is already using the new rc.conf(5) variable 888 networkfs_types, please note that it has changed 889http://www.freebsd.org/cgi/mid.cgi?db=mid&id=<9744.1009655556@axl.seasidesoftware.co.za> 890 89120011220: 892 sys/i4b/driver/i4b_ispppsubr.c has been retired. This file 893 started out its life in the ISDN4BSD project as an offspring 894 from sys/net/if_spppsubr.c, which eventually got a life of its 895 own. All the accumulated features and bug fixes of the i4b 896 version have now been merged back into the base system's 897 version now. The only user-visible change resulting from this 898 is that i4b's sppp(4) interfaces are to be managed with 899 spppcontrol(8) again, since ispppcontrol(8) has been retired 900 as well. (There has never been rc file support for 901 ispppcontrol in -current, but only in -stable. That will be 902 reverted by the time the changes are MFCed.) 903 90420011215: 905 The fdc(4) driver has been updated and now automatically 906 recognizes media in `standard' formats (like 1440 KB and 907 720 KB for a 3.5" high-density drive) when accessing the 908 default device node (e. g. /dev/fd0). The old variety of 909 floppy device nodes /dev/fd*.* is no longer present by 910 default, devices can be created (in DEVFS) on demand. They 911 will need to be customized then for `odd' densities using 912 fdcontrol(8). 913 91420011209: 915 The bugs in procfs' debugging support code have been fixed, 916 and truss(1) now works again. 917 91820011207: 919 Daily security checks have been split out to use the periodic(8) 920 scripts. Some change in configuration may be necessary. Please 921 see 922http://www.freebsd.org/cgi/mid.cgi?db=mid&id=<20011207155805.R8975@blossom.cjclark.org> 923 for details. 924 92520011204: 926 sos added VCD/SVCD support to ata driver and that needs the 927 kernel and burncd to be in sync. 928 92920011203: 930 The procfs pseudo-filesystem has now been converted to use the 931 pseudofs framework. If you have 'options PROCFS' in your 932 kernel config, you'll need to add 'options PSEUDOFS' if it's 933 not there already. 934 935 This change temporarily breaks truss(1); use ktrace(1) instead 936 until the issue has been resolved. 937 93820011202: 939 A security hole in OpenSSH involving `UseLogin yes' has been 940 patched. 941 94220011126: 943 You need to remove /usr/obj/.../usr.bin/tip before rebuilding 944 after this date. You need to do this only once. 945 94620011103: 947 Most of the awk issues have been resolved. Some rough 948 edges may be left, but for the most part things should be 949 back to "normal." For CURRENT's usual definition of "normal." 950 95120011030: 952 Awk has been upgraded to the one true awk from bell labs. Expect 953 choppy waves in the upgrade process. 954 95520011030: 956 The asr driver problem has been resolved. 957 95820011027: 959 Due to changes in other parts of the system, the asr driver 960 now causes the system to panic on boot. Do not use it pending 961 correction. Comment it out of any kernel config file that you 962 try to use from this date forward. 963 96420011025: 965 When crossbuilding, use TARGET=xxx where you used to use 966 MACHINE=xxx. You don't need to set TARGET_ARCH and TARGET, 967 unless you are changing both of them. To cross build pc98 on 968 an alpha, for example, you need to set TARGET=pc98 and 969 TARGET_ARCH=i386. 970 97120011001: 972 The kernel interface that burncd depends on has changed. 973 You must recompile both the kernel and userland applications 974 at the same time. 975 97620010929: 977 When crossbuilding, please set TARGET_ARCH rather than 978 MACHINE_ARCH to indicate the target. In the future, one will 979 set TARGET_MACHINE where you set MACHINE now. At the moment, 980 setting MACHINE alone for same MACHINE_ARCH machines works 981 (eg, you can build pc98 on an i386 machine and vice versa). 982 98320010927: 984 Some weird problems result from using ACPI on some machines. 985 To disable ACPI you can add 986 hint.acpi.0.disabled="1" 987 to /boot/loader.conf (or by putting set X=Y at the boot 988 loader "ok" prompt). 989 990 Alternatively, you can remove it from /boot/kernel/acpi.ko 991 or use the MODULES_OVERRIDE function in your kernel config 992 file and not list acpi in that list. 993 99420010924: 995 The buildworld has been fixed. You may need to install 996 the 4.x compatibility libraries for some old binaries 997 to work. Add COMPAT4X=true to your /etc/make.conf to 998 get them installed on every installworld, or execute the 999 following to get them installed only once: 1000 cd src/lib/compat/compat4x.<arch> 1001 make all install 1002 You will see ``__stdoutp undefined'' until you do this. 1003 100420010919: 1005 There's a bug in the world build process. The cross-tools 1006 are build with the NEW headers, but the OLD libc.a. This 1007 leads to all kinds of problems with the new libc. A temporary 1008 workaround is to add 1009 CFLAGS="-O -pipe -D_OLD_STDIO" 1010 before building world when upgrading from 4.x to current. This 1011 can be removed afterwards. 1012 1013 A proper fix to the buildworld target is needed. 1014 101520010918: 1016 Peter has committed his new kthread nfs client/server code. 1017 NFS may be unstable after this date. 1018 101920010912: 1020 KSE has hit the tree. Lots of things are now different in 1021 the kernel. While a few problems were introduced in the 1022 initial commit, most of the major ones have been found and 1023 corrected. 1024 102520010901: 1026 In OLDCARD, CardBus bridges appear to be stable. The work 1027 arounds described in the 20010604 entry are now no longer 1028 necessary and will be ignored. Most insert/remove problems 1029 have been rectified around this date. 1030 103120010823: 1032 named now runs as user bind and group bind rather than as 1033 root. If named_enable is set to YES in /etc/rc.conf, ensure 1034 that user bind is available in /etc/passwd (using vipw(8)) 1035 and that group bind is available in /etc/group. Also make 1036 sure that user or group bind has read (and not write) 1037 permission for your name server configuration and that it 1038 has read and write permission for your slave zone files and 1039 directory. 1040 1041 If you wish to continue to run named as root (a less secure 1042 alternative), add a line to /etc/rc.conf saying 1043 1044 named_flags= 1045 104620010709: 1047 The PAM libraries have had an API upgrade that is beyond 1048 the ability of the shared library major number to handle. 1049 It is manifested by PAM-using ports dumping core. The 1050 solution is to rebuild those ports. 1051 105220010628: 1053 The kernel compile module has moved from src/sys/compile/FOO 1054 to src/sys/${MACHINE}/compile/FOO. 1055 105620010625: 1057 The pccard modem issue from 20010613 has been corrected. 1058 OLDCARD support is still a little weak in -current. slot 1 is 1059 known not to work on some TI based cardbus bridges. Some 1060 cardbus bridges do not properly detect insert/removal events. 1061 IRQ configuration needs more safety belts. 1062 106320010617: 1064 Softupdates problems have been corrected. 1065 106620010614: 1067 Peter ripped out the linkerset support. You must, as always, 1068 rerun config after you cvsup if you are using the traditional 1069 kernel building methods. 1070 107120010613: 1072 pccard modems may not work with current after 20010604 date. Some 1073 do, others result in panics. *MAKE*SURE* that you update your 1074 config and /etc/rc.conf ala the 20010604 entry, or you will have 1075 problems (this issue will be fixed, it just hasn't been yet). 1076 107720010613: 1078 SOFTUPDATES seem to be broken since the middle of May or so. Do not 1079 use them in current. You can disable softupdates on all mounted 1080 partitions, or remove SOFTUPDATES the kernel config file. 1081 108220010612: 1083 After Peter's commits to the hints code, people have been noticing 1084 that certain devices are attached (or try to) twice. This is due 1085 to having both static hints as well as a /boot/device.hints. To 1086 work around this issue, please use only one or the other mechanism 1087 until this bug is fixed. 1088 1089 Please note that a feature of config is that if you have config 1090 file FOO and FOO.hints, it automatically adds FOO.hints to the 1091 hints.c file, whether you want it to or not. 1092 109320010610: 1094 Locale names have changed to match other systems better. 1095 109620010604: 1097 pccard support for pci cards has been committed. You must change 1098 your /etc/pccard.conf irq lines. It must match the irq used by 1099 pcic device. Interrupt storms may result if you fail to do this. 1100 Interrupt storms look a lot like a hang. 1101 1102 You must also install a new pccardd, otherwise you will get an 1103 interrupt storm at card reset time (just after it tells you what 1104 it is). 1105 1106 pccardd_flags="-I" is necessary for the time being. It tells pccardd 1107 not to ask the kernel if the interrupt is really free or not before 1108 using it. You can either change the /etc/pccard.conf irq lines to 1109 match pcic, or add "-i X" to the pccardd_flags. 1110 111120010530: 1112 INSTALL=install -C is being deprecated. If you want to do this, 1113 use COPY=-C instead. The former method will be supported for only 1114 a limited time. If you see 1115 1116install: warning: the -d and -C options may not be specified together 1117 1118 in your makeworld, then you need to migrate towards using 1119 COPY=-C. 1120 112120010525: 1122 It appears that vm is now stable enough to use again. However, 1123 there may be other problems, so caution is still urged. alpha 1124 definitely is in bad shape. 1125 112620010521: 1127 Minor repo damage has happened. This may cause problems 1128 with cvsup of ports. If you get errors, please see 1129 http://www.FreeBSD.org/cgi/query-pr.cgi?pr=27495 1130 at the bottom for details on a workaround. The error message 1131 is 1132Updater failed: Cannot delete "/usr/ports/www/jakarta-tomcat/files": Directory not empty 1133 113420010520: 1135 Vm and/or swapping are busted on -current. Please be patient. 1136 113720010519: 1138 pccard has had much reorganizational work done to it over 1139 the past few days. Everything should still work, but if 1140 not, please contact imp@freebsd.org. 1141 114220010517: 1143 ata ioctl changed. Make sure to recompile both kernel and 1144 userland at the same time. 1145 114620010517: 1147 New ncurses imported. 1148 114920010512: 1150 DEVFS is now opt out, not opt in. Barring major problems, this 1151 will be the only way to go starting July 1. 1152 115320010504: 1154 OpenSSH has been updated to 2.9. Some defaults are different, 1155 including RhostsRSAAuthentication, which changes from yes to no. 1156 115720010502: 1158 Perl breakage in 20010501 was corrected at 14:18:33 PDT. 1159 116020010501: 1161 Building perl was broken at 02:25:25 PDT. 1162 116320010430: 1164 The bug in 20010429 was corrected at 07:35:37 PDT. It is safe to 1165 go back in the water. 1166 116720010429: 1168 A bad bug was committed at 04:48:42 PDT. Don't use kernels after 1169 this date, but before the correction date. 1170 117120010423: 1172 old fsck and new kernel interactions appear to have been fixed. 1173 117420010411: 1175 fsck and the kernel were changed to handle some optimizations 1176 to directory layout. This breaks backward compatibility. 1177 Update only if you understand that you must not use the old 1178 fsck with the new kernel ever. 1179 118020010330: 1181 fsck has changed the meaning of the pass column in /etc/fstab. 1182 Please see the cvs commit to fsck.8 or the fsck.8 man page for 1183 details. It is unclear if changes to /etc/fstab are necessary. 1184 118520010319: 1186 portmap had changed name to rpcbind for maximum POLA in your 1187 current world. /etc/hosts.{allow,deny} needs changes. nfs and 1188 other rpc based programs that rely on portmapper will not work 1189 without updates to /etc/hosts.{allow,deny} and /etc/netconfig. 1190 119120010315: 1192 ata subsystem changes. ATA_ENABLE_ATAPI_DMA, ATA_ENABLE_WC 1193 and ATA_ENABLE_TAGS are no longer kernel options. They have 1194 been replaced by tunables. See ata.4 for details. 1195 119620010312: 1197 The fxp driver was converted to use miibus. If you compile 1198 fxp into your kernel statically, you will need to add miibus. 1199 120020010312: 1201 The wi device now defaults to BSS (infrastructure) mode 1202 instead of ad-hoc. 1203 120420010310: 1205 /dev/urandom should be a symbolic link to /dev/random now. 1206 Users of current not using DEVFS need to run MAKEDEV std. 1207 ssh might not work if you don't. 1208 120920010303: 1210 The ed driver has been updated. It now allows mii attachments, 1211 which means that you must include the miibus in your kernel if 1212 you use the ed driver. 1213 121420010220: 1215 The problems with libc have been corrected. It is now mostly 1216 safe to go back into the water. 1217 121820010211: 1219 The size of FILE was changed. This breaks upgrading. If 1220 you must upgrade, be prepared for pain. It also breaks almost 1221 all binaries that you've compiled on -current. You are warned 1222 that before upgrading would be a good time to do a level 0 1223 dump of your system. No, really, I mean it this time. 1224 1225 To get to the new system, you'll need to use the following 1226 workaround. Hopefully this can be sorted out so that we 1227 don't have to move this to the updating section. 1228 1229 To get around the installworld problem, do: 1230 # cd /usr/src/usr.bin/sed 1231 # make install 1232 # cd /usr/src 1233 # make installworld 1234 If that doesn't work, then try: 1235 # make -k installworld 1236 # make installworld 1237 123820010207: 1239 DEVFS is now the default. If you use vinum, make sure that you 1240 do not include devfs in your kernel as problems result. 1241 124220010205: 1243 FFS_ROOT and CD9660_ROOT have been removed or deprecated. 1244 Remove them from your config. 1245 124620010122: 1247 ****************************** WARNING ****************************** 1248 buildkernel has been changed slightly 1249 ****************************** WARNING ****************************** 1250 KERNCONF replaces the variable KERNEL for buildkernel. You 1251 should update your scripts and make.conf accordingly. 1252 125320010119: 1254 config has changed to allow DEV_FOO as a replacement for NFOO. 1255 This requires a new config to build correctly. 1256 125720010116: 1258 The kernel option I386_CPU is now mutually exclusive with the 1259 other cpu types. If you have an i386 system, be sure that it 1260 only had this line. Remove it for all other configurations. 1261 126220010110: 1263 Changes to the kernel require it and burncd be in sync. 1264 126520010102: 1266 Everyone who has hw.sndunit set to something in 1267 /etc/sysctl.conf, it is now hw.snd.unit. 1268 126920010101: 1270 ex and vi were broken by some changes to sys/queue.h. If you 1271 have a bad vi, you will see make buildworld fail with a core 1272 dump while building termcap. You can work around this problem 1273 by adding -k to your make buildworld. This will cause the 1274 build to complete and install a new vi. Once that's done, you 1275 can rebuild again without the -k to pick up anything that 1276 might have been ignored by the -k option. 1277 1278 Others have suggested that you can just rebuild libc if your 1279 vi/ex is dynamically linked, but I've not received any reports 1280 of this working. 1281 128220001228: 1283 There have been some changes to libcrypt in -current. The 1284 libscrypt/libdescrypt symlink silliness is gone and the installed 1285 libcrypt is fully functional. Be aware of this. 1286 128720001218: 1288 Linksys Fast Ethernet PCCARD cards supported by the ed driver 1289 now require the addition of flag 0x80000 to their config line 1290 in pccard.conf(5). This flag is not optional. These Linksys 1291 cards will not be recognized without it. 1292 129320001205: 1294 Important new FreeBSD-version stuff: PAM support has been worked 1295 in, partially from the "Unix" OpenSSH version. This requires 1296 adding the following in pam.conf: 1297 1298 sshd auth sufficient pam_skey.so 1299 sshd auth required pam_unix.so try_first_pass 1300 sshd session required pam_permit.so 1301 130220001031: 1303 cvs updated to 1.11. 1304 130520001020: 1306 The random device needs more entropy, so you need to make sure 1307 that you've run mergemaster to get a /etc/rc which will seed 1308 /dev/random. If you don't and the system hangs after ldconfig, 1309 then banging on the keyboard randomly until it unhangs is one 1310 workaround. 1311 131220001010: 1313 ****************************** WARNING ****************************** 1314 Sendmail has been updated. 1315 ****************************** WARNING ****************************** 1316 o mail.local(8) is no longer installed as a set-user-id binary. 1317 o sendmail(8) is now built with STARTTLS support unless NO_OPENSSL 1318 is set. 1319 o The default /etc/mail/sendmail.cf disables the SMTP EXPN and VRFY 1320 commands. 1321 o Now using sendmail's version of vacation(1). 1322 o The sendmail cf building tools (contrib/sendmail/cf) are installed 1323 in /usr/share/sendmail/cf. 1324 o sendmail.cw changed to local-host-names 1325 1326 More details can be found at 1327 http://people.freebsd.org/~imp/UPDATING/sendmail-20001010 1328 132920001009: 1330 The ports tree's new layout is in place. Be sure to update 1331 your entire ports tree, or you will have problems. 1332 133320001006: 1334 The perl build procedure no longer installs miniperl, nor uses 1335 the installed miniperl. It is recommended that you delete 1336 /usr/bin/miniperl. 1337 133820001005: 1339 This weekend the ports tree will be updated to a new layout. 1340 It will be in an inconsistent state until noted in the UPDATING 1341 file, or with asami-san's message to the relevant mailing 1342 lists. With this new layout, you'll need to update the whole 1343 tree for anything to work. 1344 134520000928: 1346 There was a change in the passwd format. Need more information. 1347 134820000916: 1349 /boot/kernel/kernel.ko -> /boot/kernel/kernel change has taken 1350 place. Please update boot loader (not the boot blocks) at the 1351 same time as your kernel. 1352 135320000914: 1354 The new pmtimer device is necessary for laptops. Failure to 1355 include the device will cause suspended laptops losing time 1356 when they resume. Include 1357 device pmtimer 1358 in your config file and 1359 hint.pmtimer.0.at="isa" 1360 to your /boot/device.hints file. 1361 136220000911: 1363 The random device has been turned into a (pseudo-)device, 1364 rather than an option. The supplied kernel config files have 1365 been updated. You will need to do something similar in your 1366 own kernel config file. 1367 Remove: 1368 options RANDOMDEV 1369 Add: 1370 device random 1371 If you prefer to load the loadable module, you need to do 1372 nothing. 1373 137420000909: 1375 The random device module has been renamed from randomdev.ko to 1376 random.ko. You will need to edit your /boot/loader.conf to 1377 reflect this if you load this module at boot time. 1378 The line should read: 1379 random_load="YES" 1380 138120000907: 1382 The SMPNG commit has happened. It should work, but if it 1383 doesn't, fallback to the PRE_SMPNG CVS tag. There are likely 1384 to be a variety of minor issues. Please see 20000905 to make 1385 sure you don't have model loading problems which might at 1386 first blush appear related to SMP. 1387 138820000906: 1389 nsswitch has been imported from NetBSD. Among other things, 1390 this means that /etc/host.conf is no longer used. See 1391 nsswitch.conf(5) instead. Note that at boot time rc.network 1392 will attempt to produce a new nsswitch.conf file for you if you 1393 don't have one, and you have host.conf. 1394 139520000905: 1396 The ucred structure changed size. This breaks the interface 1397 that mountd uses. Trying to use an older mountd with a newer 1398 kernel guarantees a panic. This means that you need to use 1399 kernels newer than today only with matching mountd, but you 1400 needed to do that anyway with the boot loader changes. 1401 140220000905: 1403 The boot loader has been updated. The new default kernel is 1404 now /boot/kernel/kernel.ko. The new default module location 1405 is /boot/kernel. 1406 1407 You *MUST* upgrade your boot loader and kernel at the same time. 1408 The easiest way to do this is to do the buildworld/buildkernel/ 1409 installkernel/installworld dance. 1410 1411 Furthermore, you are urged to delete your old /modules directory 1412 before booting the new kernel, since kldload will find stale 1413 modules in that directory instead of finding them in the correct 1414 path, /boot/kernel. The most common complaint that this cures 1415 is that the linux module crashes your machine after the update. 1416 1417 if [ ! -d /boot/kernel.old ]; then 1418 mv /modules.old /boot/kernel.old 1419 chflags noschg /kernel.old 1420 mv /kernel.old /boot/kernel.old/kernel.ko 1421 chflags schg /boot/kernel.old/kernel.ko 1422 fi 1423 142420000904: 1425 A new issue with the sendmail upgrade has come to light. 1426 /etc/aliases has moved to /etc/mail/aliases. Mergemaster will 1427 incorrectly install the default aliases in /etc/mail rather than 1428 move the old one from /etc. So you'll need to manually move the 1429 file, create a symbolic link, remove the old /etc/aliases.db and 1430 run newaliases. For safety sake, you should stop sendmail 1431 while doing this and run the upgrade when locally sourced email 1432 is not likely to be generated. 1433 143420000825: 1435 /boot/device.hints is now required for installkernel to 1436 succeed. You should copy GENERIC.hints for your architecture 1437 into /boot/device.hints. If and only if you compile hints 1438 into your kernel, then this file may be empty. Please note, 1439 if you have an empty or missing /boot/device.hints file and 1440 you neglected to compile hints into your kernel, no boot 1441 messages will appear after the boot loader tries to start the 1442 kernel. 1443 144420000821: 1445 If you do NOT have ``options RANDOMDEV'' in your kernel and 1446 you DO want the random device then add randomdev_load="YES" to 1447 /boot/loader.conf. 1448 144920000812: 1450 suidperl is now always built and installed on the system, but 1451 with permissions of 511. If you have applications that use 1452 this program, you are now required to add ENABLE_SUIDPERL=true 1453 to /etc/make.conf. If you forget to do this, 1454 chmod 4511 /usr/bin/suidperl 1455 will fix this until the next build. 1456 145720000812: 1458 sendmail has been updated from 8.9.3 to 8.11.0. Some of the more 1459 visible changes that may immediately affect your configuration 1460 include: 1461 - New default file locations from src/contrib/sendmail/cf/README 1462 - newaliases limited to root and trusted users 1463 - MSA port (587) turned on by default 1464 - New queue file naming system so can't go from 8.11 -> 8.9 1465 - FEATURE(`rbl') renamed to FEATURE(`dnsbl') 1466 - FEATURE(`nullclient') is more full featured 1467 - FEATURE(`nouucp') requires an argument: `reject' or `nospecial' 1468 - mail.local FreeBSD-only -b option changed to -B 1469 - See src/contrib/sendmail/RELEASE_NOTES for more info 1470 147120000810: 1472 suidperl (aka sperl) is no longer build by default. You must 1473 specifically define BUILD_SUIDPERL to "true" for it to be build. 1474 Furthermore, we recommend that you remove /usr/bin/sperl* and 1475 /usr/bin/suidperl files from your system unless you have a 1476 specific use for it. 1477 147820000729: 1479 Networking defaults have been tightened. Anybody upgrading 1480 /etc/defaults/rc.conf needs to add the following lines to 1481 /etc/rc.conf if they want to have the same setup 1482 afterwards (unless the variables already are set, of course): 1483 # Enable network daemons for user convenience. 1484 inetd_enable="YES" 1485 portmap_enable="YES" 1486 sendmail_enable="YES" 1487 148820000728: 1489 If you have null_load="YES" in your /boot/loader.conf, you 1490 will need to change that to nullfs_load="YES". 1491 149220000728: 1493 The "installkernel" target has changed slightly. Now even if 1494 you override KERNEL e.g. 'make installkernel KERNEL=MYKERNEL' 1495 it will install the MYKERNEL file (built with the buildkernel 1496 target) as /kernel rather than /MYKERNEL. Those who have 1497 updated their /boot/loader.conf files to point to /MYKERNEL 1498 should remove that entry or perform manual rename of /kernel 1499 to /MYKERNEL. 1500 150120000711: 1502 If you use CVSUP or CTM to get CVS trees, AND you used to get 1503 the old crypto files from internat.freebsd.org AND you check 1504 out files from the CVS tree with the cvs command, please read 1505 http://people.freebsd.org/~imp/internat.txt 1506 for details on potential problems that you might have and how 1507 to get around them. 1508 1509 If you are merely a mirror, or don't answer yes to each of the 1510 clauses above, you needn't worry. 1511 151220000711: 1513 /etc/security has been updated to print the inode number of 1514 setuid programs that have changed. You will see a large spike 1515 in the number of changed programs the first time when you run 1516 mergemaster to get a new /etc/security. 1517 151820000710: 1519 /dev/random now has good entropy collection (from the keyboard 1520 and sysmouse drivers). Please ensure that either `options 1521 RANDOMDEV' is present in your kernel config file or that 1522 `randomdev_load="YES"' is in your /boot/loader.conf. If you do 1523 not have the /dev/random driver, OpenSSL (and consequently 1524 lots of crypto tools (like SSH)) will fail with strange 1525 errors. (see below, 20000624). 1526 1527 FreeBSD-current is safe again to run Crypto. 1528 152920000709: 1530 phk made the malloc default options AJ. This may slow things 1531 down and uncover other latent bugs in the code. If you need to 1532 run at full speed, you can disable this by doing the following: 1533 ln -s aj /etc/malloc.conf 1534 153520000706: 1536 libftpio's version was accidentally bumped a few days ago. This 1537 has been corrected. You may need to remove /usr/lib/libftpio.so.6 1538 before doing your next buildworld/installworld pair. It certainly 1539 won't hurt to remove it before the update procedure. It will 1540 break fetch until a new one is built, but ftp can be used in the 1541 interim if needed. 1542 154320000705: 1544 The crypto packages have changed for the cvsup. This has been done 1545 in a backward compatible way, but the old packages will go away at 1546 some point in the future. Look at /usr/share/examples/cvsup for 1547 details. 1548 154920000704: 1550 With the new sys/modules/sound/drivers/*, you will need to 1551 set SYSDIR until you do an installworld after July 7th. 1552 155320000704: 1554 rc.shutdown and rc will now call the rc.d scripts with start 1555 or stop. This may cause some harmless warnings from older 1556 rc.d scripts that haven't been updated. 1557 155820000630: 1559 The libfetch based version of fetch has gone into the tree. 1560 Minor problems may result on some of the less popular sites, 1561 which should be reported to des@freebsd.org. 1562 156320000625: 1564 From approximately this date forward, one must have the crypto 1565 system installed in order to build the system and kernel. 1566 While not technically strictly true, one should treat it as 1567 required and grab the crypto bits. If you are grabbing CVS 1568 trees, src-all and cvs-crypto should be treated as if they 1569 were required. You should check with the latest collections 1570 to make sure that these haven't changed. 1571 157220000624: 1573 Mark Murray just committed the first parts of a cleanup of 1574 /dev/zero, et al. This is also cleaning up /dev/random. 1575 The entropy is disconnected, so DO NOT USE VERSIONS OF FREEBSD 1576 -CURRENT FROM THIS POINT to 2000710 for cryptographic services 1577 until Mark can merge in the fixes to this work in progress. 1578 openssh and openssl should not be used to generate keys from this 1579 date to the completion of the work. 1580 1581 If you must operate at this reduced level of security, add ' 1582 options RANDOMDEV' to your kernel or modload the randomdev 1583 module. You may also need to copy a new MAKEDEV to /dev and 1584 recreate the random and urandom devices. 1585 158620000622: 1587 The license on the softupdates is now a standard 2 clause 1588 BSD license. You may need to remove your symbolic links 1589 that used to be required when updating. 1590 159120000621: 1592 Scott Flatman <sf@aracnet.com> sent in a decent write-up on 1593 the config file update procedure. 1594 http://people.freebsd.org/~imp/config-upd.html 1595 NOTE: LINT is gone. It has been replaced with NOTES. NOTES 1596 isn't buildable. However, you can generate a LINT file: 1597 cd /sys/<ARCH>/conf && make LINT 1598 159920000620: 1600 Binutils 2.10 have hit the tree, or will shortly. As soon 1601 as they do, the problem noted in 20000522 will be resolved and 1602 that workaround will no longer be required. 1603 160420000615: 1605 phk removed the compatibility creation of wd devices in the 1606 ad driver. If you haven't done so already, you must update 1607 your fstab, etc to use the ad devices instead of the wd 1608 devices. 1609 1610 In addition, you'll need to update your boot blocks to a 1611 more modern version, if you haven't already done so. Modern 1612 here means 4.0 release or newer (although older releases 1613 may work). 1614 161520000612: 1616 Peter took an axe to config(8). Be sure that you read his mail 1617 on the topic before even thinking about updating. You will 1618 need to create a /boot/device.hints or add a hints directive 1619 to your config file to compile them in statically. The format 1620 of the config file has changed as well. Please see GENERIC or 1621 NEWCARD for examples of the new format. 1622 1623 Indirectly, this also breaks USERCONFIG. Unless a newer entry 1624 says that it has been fixed, assume that must use the hints mechanism 1625 in the loader if you need to use a machine with very old ISA cards 1626 in it. 1627 162820000522: 1629 A new set of binutils went into the tree today. Anybody 1630 building a kernel after this point is advised that they need 1631 to rebuild their binutils (or better yet do a 1632 buildworld/installworld) before building a new kernel. 1633 1634 Due to bugs in binutils, using malloc options (eg /etc/malloc.conf 1635 or MALLOC_OPTIONS env var) J will cause ld to dump core. It 1636 is recommended that you don't set this option until the problem 1637 is resolved. 1638 163920000513: 1640 The ethernet drivers were all updated to clean up the BPF handling. 1641 164220000510: 1643 The problems with boot blocks on the alphas have been corrected. 1644 This will require some care in updating alphas. A new libstand 1645 is requires for the boot blocks to build properly. 1646 164720000503: 1648 Recompile all kld modules. Proper version dependency info 1649 is now available. 1650 165120000502: 1652 Modules have been disconnected from the buildworld tree and 1653 connected to the kernel building instead. 1654 165520000427: 1656 You may need to build gperf 1657 cd /usr/src/gnu/usr.bin/gperf && make depend all install 1658 when upgrading from 4.0 -> current. The build system now uses 1659 an option only in -current. 1660 166120000417: 1662 The method that we brand ELF binaries has changed to be more 1663 acceptable to the binutils maintainers. You will need to 1664 rebrand your ELF binaries that aren't native. One problem 1665 binary is the Linux ldconfig. After your make world, but 1666 before you reboot, you'll need to issue: 1667 brandelf -t Linux /compat/linux/sbin/ldconfig 1668 if you have Linux compatibility enabled on your machine. 1669 167020000320: 1671 If you have really bad/marginal IDE drives, you may find they 1672 don't work well. Use pio mode instead. The easiest way to 1673 cope if you have a problem combination is to add: 1674 /sbin/sysctl hw.ata.ata_dma=0 1675 to the start of /etc/rc.conf. 1676 167720000319: 1678 The ISA and PCI compatibility shims have been connected to the 1679 options COMPAT_OLDISA and COMPAT_OLDPCI. If you are using old 1680 style PCI or ISA drivers (i.e. tx, voxware, etc.) you must 1681 include the appropriate option in your kernel config. Drivers 1682 using the shims should be updated or they won't ship with 1683 5.0-RELEASE, targeted for 2001. 1684 168520000318: 1686 We've entered the traditional post release dumping party. 1687 Large kernel changes are being committed and are in the 1688 works. It is important to keep the systems' klds and kernel 1689 in sync as kernel interfaces and structures are changing. 1690 Before reporting kernel panics, make sure that all modules 1691 that you are loading are up to date. 1692 169320000315: 1694 If you are upgrading from an older version of FreeBSD, you 1695 need to update your boot blocks as well. 'disklabel -B ad0' 1696 will do the trick. This isn't critical until you remove your 1697 wd device entries in /dev, at which point your system will not 1698 boot. 1699 170020000315: 1701 4.0 RELEASE shipped. Please see the 4.0 UPDATING file for how 1702 to upgrade to 4.0 from 3.x. 1703 1704COMMON ITEMS: 1705 1706 # NOTE: 5.x below applies to 6.0-currrent as well, for the 1707 # momemnt. 4.any -> 5.any upgrade support will remain in 1708 # place for 6.0 current, but after 5.3 RELEASE, the 4.any -> 1709 # 6.0-current upgrade path will require moving through 5.3 1710 # RELEASE or newer. 1711 1712 General Notes 1713 ------------- 1714 Avoid using make -j when upgrading. From time to time in the 1715 past there have been problems using -j with buildworld and/or 1716 installworld. This is especially true when upgrading between 1717 "distant" versions (eg one that cross a major release boundary 1718 or several minor releases, or when several months have passed 1719 on the -current branch). 1720 1721 Sometimes, obscure build problems are the result of environment 1722 poisoning. This can happen because the make utility reads its 1723 environment when searching for values for global variables. 1724 To run your build attempts in an "environmental clean room", 1725 prefix all make commands with 'env -i '. See the env(1) manual 1726 page for more details. 1727 1728 To build a kernel 1729 ----------------- 1730 If you are updating from a prior version of FreeBSD (even one just 1731 a few days old), you should follow this procedure. With a 1732 /usr/obj tree with a fresh buildworld, 1733 make -DALWAYS_CHECK_MAKE buildkernel KERNCONF=YOUR_KERNEL_HERE 1734 make -DALWAYS_CHECK_MAKE installkernel KERNCONF=YOUR_KERNEL_HERE 1735 1736 To just build a kernel when you know that it won't mess you up 1737 -------------------------------------------------------------- 1738 This assumes you are already running a 5.X system. Replace 1739 ${arch} with the architecture of your machine (e.g. "i386", 1740 "alpha", "amd64", "ia64", "pc98", "sparc64", etc). 1741 1742 cd src/sys/${arch}/conf 1743 config KERNEL_NAME_HERE 1744 cd ../compile/KERNEL_NAME_HERE 1745 make depend 1746 make 1747 make install 1748 1749 If this fails, go to the "To build a kernel" section. 1750 1751 To rebuild everything and install it on the current system. 1752 ----------------------------------------------------------- 1753 # Note: sometimes if you are running current you gotta do more than 1754 # is listed here if you are upgrading from a really old current. 1755 1756 <make sure you have good level 0 dumps> 1757 <maybe fix /etc/fstab> [7] 1758 make buildworld 1759 make kernel KERNCONF=YOUR_KERNEL_HERE 1760 [1] 1761 <reboot in single user> [3] 1762 src/etc/rc.d/preseedrandom [10] 1763 mergemaster -p [5] 1764 make installworld 1765 mergemaster [4] 1766 <reboot> 1767 1768 1769 To cross-install current onto a separate partition 1770 -------------------------------------------------- 1771 # In this approach we use a separate partition to hold 1772 # current's root, 'usr', and 'var' directories. A partition 1773 # holding "/", "/usr" and "/var" should be about 2GB in 1774 # size. 1775 1776 <make sure you have good level 0 dumps> 1777 <boot into -stable> 1778 make buildworld 1779 <maybe newfs current's root partition> 1780 <mount current's root partition on directory ${CURRENT_ROOT}> 1781 make installworld DESTDIR=${CURRENT_ROOT} 1782 make buildkernel KERNCONF=YOUR_KERNEL_HERE 1783 cp src/sys/${ARCH}/conf/GENERIC.hints \ 1784 ${CURRENT_ROOT}/boot/device.hints # as needed 1785 make installkernel KERNCONF=YOUR_KERNEL_HERE DESTDIR=${CURRENT_ROOT} 1786 cd src/etc; make distribution DESTDIR=${CURRENT_ROOT} # if newfs'd 1787 cp /etc/fstab ${CURRENT_ROOT}/etc/fstab # if newfs'd 1788 <edit ${CURRENT_ROOT}/etc/fstab to mount "/" from the correct partition> 1789 <reboot into current> 1790 <do a "native" rebuild/install as described in the previous section> 1791 <maybe install compatibility libraries from src/lib/compat> 1792 <reboot> 1793 1794 1795 To upgrade in-place from 4.x-stable to current 1796 ---------------------------------------------- 1797 # 5.x uses more space than 4.x. Also, the location of kernel 1798 # modules has changed. If you are installing 5.x onto a 4.x 1799 # system, you'll need about 30MB of free disk space on your / 1800 # partition. If you have less than this, you may encounter difficult 1801 # to back out of problems with this procedure. If /tmp is on 1802 # the / partition, you may want to completely remove all its content 1803 # before upgrading, as this can be a common source of shortage of 1804 # space on /. 1805 1806 <make sure you have good level 0 dumps> 1807 <maybe fix /etc/fstab> [7] 1808 make buildworld [9] 1809 cp sys/${MACHINE}/conf/GENERIC.hints /boot/device.hints [2] 1810 make kernel KERNCONF=YOUR_KERNEL_HERE [8] 1811 cd sys/boot ; make STRIP="" install [6] 1812 [1] 1813 <reboot in single user> [3] 1814 src/etc/rc.d/preseedrandom [10] 1815 mergemaster -p [5] 1816 rm -rf /usr/include/g++ 1817 make installworld 1818 mergemaster -i [4] 1819 <reboot> 1820 1821 Make sure that you've read the UPDATING file to understand the 1822 tweaks to various things you need. At this point in the life 1823 cycle of current, things change often and you are on your own 1824 to cope. The defaults can also change, so please read ALL of 1825 the UPDATING entries. 1826 1827 Also, if you are tracking -current, you must be subscribed to 1828 freebsd-current@freebsd.org. Make sure that before you update 1829 your sources that you have read and understood all the recent 1830 messages there. If in doubt, please track -stable which has 1831 much fewer pitfalls. 1832 1833 [1] If you have third party modules, such as vmware, you 1834 should disable them at this point so they don't crash your 1835 system on reboot. 1836 1837 [2] If you have legacy ISA devices, you may need to create 1838 your own device.hints to reflect your unique hardware 1839 configuration. 1840 1841 [3] From the bootblocks, boot -s, and then do 1842 fsck -p 1843 mount -u / 1844 mount -a 1845 cd src 1846 adjkerntz -i # if CMOS is wall time 1847 Also, when doing a major release upgrade, it is required that 1848 you boot into single user mode to do the installworld. 1849 For the 4.x -> 5.x upgrade, you will also see many messages about 1850 needing to recompile your userland. These are harmless and can 1851 be ignored while you proceed to the next step. 1852 1853 [4] Note: This step is non-optional. Failure to do this step 1854 can result in a significant reduction in the functionality of the 1855 system. Attempting to do it by hand is not recommended and those 1856 that pursue this avenue should read this file carefully, as well 1857 as the archives of freebsd-current and freebsd-hackers mailing lists 1858 for potential gotchas. 1859 1860 [5] Usually this step is a noop. However, from time to time 1861 you may need to do this if you get unknown user in the following 1862 step. It never hurts to do it all the time. You may need to 1863 install a new mergemaster (cd src/usr.sbin/mergemaster && make 1864 install) after the buildworld before this step if you last updated 1865 from current before 20020224 or from -stable before 20020408. 1866 1867 [6] 4.x boot loader can be used to boot a 5.x system, however 1868 it is difficult to do that at best. If you wish to try, then 1869 you should interrupt the boot and at the ok prompt type: 1870 ok unload 1871 ok boot /boot/kernel/kernel 1872 If this fails to work, you must install a new boot loader as 1873 described here. 1874 1875 [7] Before you upgrade, please make sure that you are not using 1876 compatibility slices. These are device names of the form /dev/ad0a 1877 without the actual slice name. These will break with 5.x and newer. 1878 You generally must update these entries to use the post FreeBSD 1879 2.x form of /dev/ad0s1a. i386 and pc98 are affected, while alpha 1880 is not. 1881 1882 [8] In order to have a kernel that can run the 4.x binaries 1883 needed to do an installworld, you must include the COMPAT_FREEBSD4 1884 option in your kernel. Failure to do so may leave you with a system 1885 that is hard to boot to recover. 1886 1887 Make sure that you merge any new devices from GENERIC since the 1888 last time you updated your kernel config file. 1889 1890 [9] When checking out sources, you must include the -P flag to have 1891 cvs prune empty directories. 1892 1893 If CPUTYPE is defined in your /etc/make.conf, make sure to use the 1894 "?=" instead of the "=" assignment operator, so that buildworld can 1895 override the CPUTYPE if it needs to. 1896 1897 MAKEOBJDIRPREFIX must be defined in an environment variable, and 1898 not on the command line, or in /etc/make.conf. buildworld will 1899 warn if it is improperly defined. 1900 1901 In case you would like to avoid installing new packages of everything, 1902 you might want to uncomment the "COMPAT4X= YES" entry, so that 4.x 1903 compatibility libraries are built which should allow you to continue 1904 using your existing software for a while. Alternatively, you can 1905 install the misc/compat4x port. 1906 1907 [10] In order to create temporary files, /dev/random must be 1908 initialized by feeding data into it. src/etc/rc.d/preseedrandom 1909 takes care of this. 1910FORMAT: 1911 1912This file contains a list, in reverse chronological order, of major 1913breakages in tracking -current. Not all things will be listed here, 1914and it only starts on March 15, 2000. Updating files can found in 1915previous releases if your system is older than this. 1916 1917Copyright information: 1918 1919Copyright 1998-2004 M. Warner Losh.
