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 7Items affecting the ports and packages system can be found in 8/usr/ports/UPDATING. Please read that file before running 9portupgrade. Important recent entries: 20040724 (default X changes). 10 11[[ The UPDATING file will be trimmed to 20040814 on or about Oct 1, 2004 ]] 12 13NOTE TO PEOPLE WHO THINK THAT FreeBSD 6.x IS SLOW: 14 FreeBSD 6.x has many debugging features turned on, in 15 both the kernel and userland. 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 2620041116: 27 Support for systems with an 80386 CPU has been removed. Please 28 use FreeBSD 5.x or earlier on systems with an 80386. 29 3020041110: 31 We have had a hack which would mount the root filesystem 32 R/W if the device were named 'md*'. As part of the vnode 33 work I'm doing I have had to remove this hack. People 34 building systems which use preloaded MD root filesystems 35 may need to insert a "/sbin/mount -u -o rw /dev/md0 /" in 36 their /etc/rc scripts. 37 3820041102: 39 The size of struct tcpcb has changed again due to the removal 40 of RFC1644 T/TCP. You have to recompile userland programs that 41 read kmem for tcp sockets directly (netstat, sockstat, etc.) 42 4320041022: 44 The size of struct tcpcb has changed. You have to recompile 45 userland programs that read kmem for tcp sockets directly 46 (netstat, sockstat, etc.) 47 4820041018: 49 A major sweep over the tty drivers to elimnate approx 3100 50 lines of copy&pasted code have been performed. As a part of 51 this change some tty devices have changed names: 52 sio devices are now named: {tty,cua}d%d[.init,.lock] 53 ucom devices are now named: {tty,cua}U%d[.init,.lock] 54 For other drivers see the commit logs. 55 5620041007: 57 The FreeBSD keyword is no longer a requirement for a valid 58 rc.d script. The rc(8) and rc.shutdown(8) scripts no longer check 59 for the existence of this keyword when ordering rc.d scripts. 60 This change touches most of the file in /etc/rc.d; therefore, 61 if you have not modified any files in that directory it may 62 be easier to rm -rf /etc/rc.d and then use the -i switch with 63 mergemaster(8). 64 6520041007: 66 One of the syscalls the 1:1 threading library libthr uses has 67 changed, thus breaking ABI compatibility. Make sure you rebuild 68 this library with the kernel. 69 7020041001: 71 The following libraries had their version number bumped up: 72 /lib/libm.so.2 -> libm.so.3 73 /lib/libreadline.so.4 -> libreadline.so.5 74 /usr/lib/libhistory.so.4 -> libhistory.so.5 75 /usr/lib/libopie.so.2 -> libopie.so.3 76 /usr/lib/libpcap.so.2 -> libpcap.so.3 77 FreeBSD 4.10 versions of these libraries will be added to the 78 compat4x collection. If you expect to be able to run old 4.X 79 executables you will need to remove the old versions of these 80 libraries. However note that any 5.X executables you have built 81 will stop working once you remove those old libraries. You should 82 have all your ports/packages rebuilt before removing the old 83 libraries. 84 8520040929: 86 The pfil API has gained an additional argument to pass an inpcb. 87 You should rebuild all pfil consuming modules: ipfw, ipfilter 88 and pf. 89 9020040928: 91 If named is enabled, the default is now to run it in a chroot 92 "sandbox." For users with existing configurations in 93 /etc/namedb the migration should be simple. Upgrade your 94 world as usual, then after installworld but before 95 mergemaster do the following: 96 97 If named is running: /etc/rc.d/named stop 98 cd /etc 99 mv namedb namedb.bak 100 mkdir -p /var/named/etc/namedb 101 cp -Rp namedb.bak/* /var/named/etc/namedb/ 102 mergemaster (with your usual options) 103 If using the generated localhost* files: 104 cd /var/named/etc/namedb 105 /bin/sh make-localhost 106 rm -f localhost-v6.rev localhost.rev 107 /etc/rc.d/syslogd restart 108 /etc/rc.d/named start 109 110 If you are using a custom configuration, or if you have 111 customised the named_* variables in /etc/rc.conf[.local] 112 then you may have to adjust the instructions accordingly. 113 It is suggested that you carefully examine the new named 114 variables in /etc/defaults/rc.conf and the options in 115 /var/named/etc/namedb/named.conf to see if they might 116 now be more suitable. 117 11820040925: 119 BIND 9 has been imported into the base, and is now fully 120 functional. BIND 8 has now been removed. There are numerous 121 differences between BIND 8 and 9, and users with critical 122 named installations should read the migration documentation 123 in /usr/share/doc/bind9/misc/migration. There is also a 124 new instruction manual in /usr/share/doc/bind9/arm. 125 126 The key differences that most users will experience are in 127 how picky BIND 9 is about zone file format. If you are using 128 named as a resolving (caching) name server, you will likely 129 not have trouble. 130 131 The following files are part of the old BIND 8 installation 132 and should be removed: 133 /usr/bin/dnskeygen /usr/bin/dnsquery /usr/libexec/named-xfer 134 /usr/sbin/named.restart /usr/sbin/ndc 135 136 The following files have moved to /usr/bin, and should be 137 removed from their old locations: 138 /usr/sbin/nslookup /usr/sbin/nsupdate 139 14020040914: 141 The format of the pflogd(8) logfile "/var/log/pflog" has changed for 142 architectures that have a 64 bit long type to make it compatible to 143 the standard pcap format. In order to prevent corruption move away 144 any old logfile before using a new pflogd(8). 145 14620040906: 147 debug.witness_* has been renamed to debug.witness.*. There are 148 compatibility tunables left in for a few days. Update loader.conf 149 as necessary. 150 15120040902: 152 The ifi_epoch change has been reverted because the ABI breakage 153 was too extensive. If you are running with a kernel/userland 154 containing the initial change (20040830), you should heed the 155 warning about ifconfig incompatibility when upgrading again. 156 With this change, 5.3 and 6.0 ifconfigs and kernels are once 157 again interoperable. 158 15920040830: 160 A new variable, ifi_epoch, has been added to struct if_data 161 which is part if struct ifnet. This means all network drivers 162 and network monitoring applications need to be recompiled. 163 164 WARNING WARNING WARNING WARNING WARNING WARNING WARNING 165 166 This also breaks ifconfig compatibility. An old ifconfig will 167 not work with the new kernel and a new ifconfig will not work 168 with the old. It is strongly recommended that you make a copy 169 of your old ifconfig before installworld. If you are installing 170 remotely, you must copy over a new ifconfig before rebooting in 171 to the new kernel. 172 17320040828: 174 The default configuration for the network stack has been changed 175 such that it now runs without the Giant lock unless configured 176 otherwise. If you experience network-related instability, you 177 may wish to try setting "debug.mpsafenet=0" or compiling the 178 kernel with "options NET_WITH_GIANT". Details on the netperf 179 project may be found at: 180 181 http://www.watson.org/~robert/freebsd/netperf/ 182 183 Including the 20040828 announcement of configuration change 184 details. 185 18620040827: 187 PFIL_HOOKS are a fixed part of the network stack now and do not 188 need to be specified in the kernel configuration file anymore. 189 19020040819: 191 Netgraph changed its message format slightly to align the data 192 portion well on 64 bit machines. 193 Netgraph using utilities (e.g. ngctl, nghook, ppp, mpd, 194 pppoed, bluetooth, ATM) should be recompiled when a new kernel 195 is installed. 196 19720040817: 198 IPFW has been converted to use PFIL_HOOKS. This change is 199 transparent to userland and preserves the ipfw ABI. The ipfw 200 core packet inspection and filtering functions have not been 201 changed, only how ipfw is invoked is different. Note that 202 "option PFIL_HOOKS" is required to use IPFIREWALL compiled 203 into the kernel or as KLD. 204 20520040814: 206 The RANDOM_IP_ID option has been replaced by the sysctl 207 net.inet.ip.random_id. If you had RANDOM_IP_ID in your kernel then 208 you may want to add "net.inet.ip.random_id=1" to /etc/sysctl.conf. 209 21020040807: 211 The size of 'struct ifnet' has changed due to the addition of the 212 if_carp placeholder. All kernel modules implementing network 213 interfaces must be recompiled as a result. 214 21520040806: 216 Module loading has been fixed. Some older installations will 217 drop proper module_path initialization and modules will fail to 218 load properly. If you have a line in /boot/loader.rc that says: 219 "initialize drop", do (i386 only): 220 cp /usr/src/sys/boot/i386/loader/loader.rc /boot/loader.rc 221 chown root:wheel /boot/loader.rc 222 chmod 444 /boot/loader.rc 223 22420040802: 225 making /dev/(null|zero) into a module proved to be too unpopular, 226 so this bit has been revoked from the previous (20040801) entry. 227 22820040801: 229 The /dev/mem, /dev/io /dev/(null/zero) devices are now modules, 230 so you may wish to add them to your kernel config file. See 231 GENERIC for examples. 232 23320040728: 234 System compiler has been upgraded to GCC 3.4.2-pre. As with any major 235 compiler upgrade, there are several issues to be aware of. GCC 3.4.x 236 has broken C++ ABI compatibility with previous releases yet again 237 and users will have to rebuild all their C++ programs with the new 238 compiler. If you are getting run-time error such as 239 /libexec/ld-elf.so.1: Undefined symbol "_ZNSs20_S_empty_rep_storageE" 240 This entry does apply to you. 241 242 A new unit-at-a-time optimization mode, which is default in this 243 compiler release, is more aggressive in removing unused static 244 symbols. This is the likely cause of 'make buildworld' breakages 245 with non-default CFLAGS where optimization level is set to -O2 246 or higher. 247 248 With the upgrade of the system compiler, the kernel has been upgraded 249 to match the new system compiler. This makes it impossible to build 250 a new kernel with the old compiler. Upgrade your system via 251 make buildworld and make kernel (see below) to fix this problem. 252 25320040727: 254 The size of 'struct ifnet' has changed due to the addition of 255 the IFF_NEEDSGIANT flag (and what it implies). All kernel 256 modules implementing network interfaces must be recompiled as 257 a result. 258 25920040716: 260 The sound device drivers are renamed. `sound' is always required, 261 while `snd_*' should be configured accordingly to your hardware. 262 Refer to NOTES for the detail of the drivers. 263 26420040710: 265 __FreeBSD_version bumped to 502122. 266 26720040710: 268 The console initialization on Alpha has been reworked and is now 269 identical to other platforms. This means that the hardcoding of 270 the serial console and the debug port has been removed. As such, 271 hints are now required for the sio(4) driver to become a console 272 or debug port. The NO_SIO option has been decommissioned because 273 of this. 274 27520040710: 276 A revamp of the debugging code in the kernel with some visible 277 changes beyond just the debugging experience: 278 o The DDB option is now specific to the DDB debugger backend 279 and should not be used any more for conditional compilation 280 of debugging code for when debugging is enabled. Use the KDB 281 option for this. 282 o The WITNESS_DDB, DDB_TRACE and DDB_UNATTENDED options have 283 been renamed to WITNESS_KDB, KDB_TRACE and KDB_UNATTENDED 284 respectively. This is in line with the first bullet. 285 o The remote GDB support has been untangled from DDB and needs 286 to be enabled separately now. Use the GDB option for this. 287 o The GDB_REMOTE_CHAT option has been removed. Support for this 288 homegrown feature is discontinued. The GDB remote protocol 289 supports console output and it makes sense to use that. 290 o The DDB_NOKLDSYM option has been removed. The DDB debugger 291 now supports both direct symbol table lookups as well as KLD 292 symbol lookups through the linker. 293 29420040708: 295 Bluetooth code has been marked as non-i386 specific. 296 __FreeBSD_version has been bumped to 502121 to mark this change. 297 29820040702: 299 The native preemption has been added to the kernel scheduler. 300 There is some report that the ULE scheduler was broken in some 301 machines and we encourage users using the ULE scheduler either 302 stick with a known good kernel, or temporarily switch to the 4BSD 303 scheduler as a workaround. 304 30520040630: 306 The netgraph ABI version number has been incremented to indicate 307 an incompatible change in the ABI. Old netgraph nodes will refuse 308 to attach until recompiled. Netgraph now uses mbuf tags to move 309 metadata and this commit removes its home-grown metadata facility. 310 Nodes should just recompile, unless they use metadata, in which 311 case the changes are simple; the file ng_ksocket.c serves as an 312 example of such changes. 313 314 This also broke i4b, although the compile problem has been papered 315 over. 316 31720040630: 318 ACPI has been updated to disable known-bad BIOS revisions. A message 319 will be printed on the console indicating that ACPI has been disabled 320 automatically and that the user should use a newer BIOS, if possible. 321 If you think ACPI does work on your system and want to override 322 this (i.e., for testing), set hint.acpi.0.disabled="0" at the 323 loader prompt. 324 32520040623: 326 pf was updated to OpenBSD-stable 3.5 and pflogd(8) is privilege 327 separated now. It uses the newly created "_pflogd" user/group 328 combination. If you plan to use pflogd(8) make sure to run 329 mergemaster -p or install the "_pflogd" user and group manually. 330 33120040622: 332 Network interface cloning has been overhauled. This change will 333 require a recompile of modules using cloning and modification of 334 external ones to the new API. __FreeBSD_version has been bumped 335 to 502119 to mark this change. Additionally, users creating 336 stf(4) interfaces via "ifconfig stf" will need to update their 337 scripts as this will create an interface named "stf" instead of 338 "stf0" and ifconfig will not print "stf0" to stdout. 339 34020040621: 341 On 20040524, the /etc/rc.d/nsswitch script was modified to 342 automatically create /etc/nsswitch.conf on startup if it did 343 not already exist. Unfortunately, an error in the man page 344 was carried over to the script, resulting in incorrect 345 nsswitch settings. The simplest remedy is to remove both 346 /etc/nsswitch.conf and /etc/host.conf; they will be recreated 347 during the next reboot. 348 34920040614: 350 The return value of sema_timedwait(9) has been changed to 351 make it consistent with cv_timedwait(9). Be sure to recompile 352 the ips module and any third-party modules which call 353 sema_timedwait. 354 35520040613: 356 ALTQ is now linked to the build. This breaks ABI for struct ifnet. 357 Make sure to recompile modules and any userland that makes use of 358 sizeof(struct ifnet). In order to get the altq headers in place 359 please recompile and reinstall world. 360 36120040607: 362 Splitting kern_thread.c into 2 files (adding kern_kse.c) 363 requires that you re-run config after updating your tree. 364 36520040601: 366 The MIDI drivers have been removed. Until the new module-friendly 367 ones are merged, remove or comment out midi and seq from your 368 kernel configuration. 369 37020040423: 371 Due to a new option in ipfw (versrcreach) the ipfw(8) command 372 needs to be recompiled. Normal accept/reject rules without 373 options are not affected but those with options may break until 374 ipfw(8) is recompiled. 375 37620040420: 377 Due to changes in the callout ABI, kernels compiled after this 378 date may be incompatible with kernel modules compiled prior to 379 20040406. 380 38120040414: 382 The PCI bus power state stuff has been turned on. If this causes 383 problems for your system, please disable it using the tunable 384 hw.pci.do_powerstate=0. 385 38620040412: 387 The bulk of the pci problems have been fixed, although the floppy 388 drive is still broken. 389 39020040410: 391 A substantial update to the pci bus resource and power management 392 have been committed. Expect a bumpy ride for a few days until 393 the unanticipated problems have been resolved. 394 39520040409: 396 Due to changes in the the Yarrow initialization process, 397 /dev/random needs to be fed before operations requiring 398 temp files can succeed in single user mode. This includes 399 running "make installworld". /dev/random may be fed by running 400 "/etc/rc.d/initrandom start" or with 20040415 source by running 401 "/etc/rc.d/preseedrandom". 402 40320040322: 404 The debug.mpsafenet tunable controls whether the kernel Giant 405 lock is held across the lower levels of the network stack, and 406 by default is turned off. In the few days following 20040322, 407 the behavior of debug.mpsafenet will change such that this 408 tunable controls Giant over all levels of the network stack. 409 If you are currently setting debug.mpsafenet to 1, you should 410 set it back to 0 (the default) again during the change-over. 411 An additional note will be added to UPDATING when sufficient 412 locking is merged to permit this to take place. 413 41420040310: 415 The FreeBSD/sparc64 platform is changing time_t from 32-bits to 416 64-bits. This is a very major incompatible change, so people 417 using FreeBSD/sparc64 *must* read the UPDATING.64BTT file for 418 detailed instructions on how to make this upgrade. People 419 upgrading FreeBSD on other platforms can ignore this event. 420 42120040308: 422 The packet filter (pf) is now installed with the base system. Make 423 sure to run mergemaster -p before installworld to create required 424 user account ("proxy"). If you do not want to build pf with your 425 system you can use the NO_PF knob in make.conf. 426 Also note that pf requires "options PFIL_HOOKS" in the kernel. The 427 pf system consists of the following three devices: 428 device pf # required 429 device pflog # optional 430 device pfsync # optional 431 43220040303: 433 If you are having trouble with the libc_r -> libpthread transition 434 (see the 20040130 entry), place the following lines at the top of 435 /etc/libmap.conf: 436 437 libc_r.so.5 libpthread.so.1 438 libc_r.so libpthread.so 439 440 This will cause all programs and libraries linked against libc_r 441 to use libpthread instead. 442 44320040226: 444 Some sshd configuration defaults have changed: protocol version 1 445 is no longer enabled by default, and password authentication is 446 disabled by default if PAM is enabled (which it is by default). 447 OpenSSH clients should not be affected by this; other clients may 448 have to be reconfigured, upgraded or replaced. 449 45020040225: 451 The ABIs defined in <resolv.h> and <netdb.h> have been updated 452 to support improved reentrancy. Multi-threaded programs that 453 reference the "_res" or "h_errno" symbols may experience some 454 problems if they are not recompiled. Single-threaded programs 455 should remain unaffected. 456 45720040225: 458 routed has been updated in the base system from the vendor 459 sources, routed v2.27, from rhyolite.com. This change means that 460 for users who use RIP's MD5 authentication feature, FreeBSD 461 -CURRENT's routed is now incompatible with previous versions 462 of FreeBSD; however it is now compatible with implementations 463 from Sun, Cisco and other vendors. 464 46520040224: 466 The tcpcb structure has changed and makes a recompile of libkvm 467 and related userland network utilities necessary. 468 46920040222: 470 The cdevsw structure has changed in two externally visible ways. 471 First, the sense of the D_GIANT flag has changed to D_NEEDSGIANT. 472 Second, the d_version field must be filled in with D_VERSION. 473 Drivers outside the tree will need to be updated. 474 47520040207: 476 The /etc/rc.d/ttys script has been removed. It is no longer 477 necessary since devfs has been mandatory for some time. 478 47920040130: 480 libkse has been renamed back to libpthread and is now the 481 default threads library. The gcc -pthread option has also 482 been changed to link to libpthread instead of libc_r. For 483 alpha and sparc64 machines, libkse is not renamed and links 484 are installed so that libpthread points to libc_r. Until 485 the ports system is updated to handle this change, it is 486 recommended that folks install an /etc/libmap.conf(5) that 487 maps libc_r to libpthread. If you have any binaries or 488 libraries linked to libkse, then it is also recommended 489 that you map libkse to libpthread. Anyone that is using 490 nvidia supplied drivers and libraries should use a libmap.conf 491 that maps libpthread to libc_r since their drivers/libraries 492 do not work with libpthread. 493 49420040125: 495 ULE has entered into its probationary period as the default scheduler 496 in GENERIC. For the average user, interactivity is reported to be 497 better in many cases. On SMP machines ULE will be able to make more 498 efficient use of the available parallel resources. If you are not 499 running it now, please switch over, replacing the kernel option 500 SCHED_4BSD with SCHED_ULE. 501 50220040125: 503 Move LongRun support out of identcpu.c, where it hardly 504 belongs, into its own file and make it opt-in, not mandatory, 505 depending on CPU_ENABLE_LONGRUN config(8) option. 506 50720031213: 508 src/lib/libc/gen/initgroups.c:1.8 now causes logins to fail 509 if the login process is unable to successfully set the 510 process credentials to include all groups defined for the 511 user. The current kernel limit is 16 groups; administrators 512 may wish to check that users do not have over 16 groups 513 defined, or they will be unable to log in. 514 51520031203: 516 The ACPI module has been reactivated. It is no longer required 517 to compile ACPI support into kernels statically. 518 51920031112: 520 The statfs structure has been updated with 64-bit fields to 521 allow accurate reporting of multi-terabyte filesystem 522 sizes. You should build world, then build and boot the new kernel 523 BEFORE doing a `installworld' as the new kernel will know about 524 binaries using the old statfs structure, but an old kernel will 525 not know about the new system calls that support the new statfs 526 structure. 527 Note that the backwards compatibility is only present when the 528 kernel is configured with the COMPAT_FREEBSD4 option. Since 529 even /bin/sh will not run with a new kernel without said option 530 you're pretty much dead in the water without it. Make sure you 531 have COMPAT_FREEBSD4! 532 Running an old kernel after a `make world' will cause programs 533 such as `df' that do a statfs system call to fail with a bad 534 system call. Marco Wertejuk <wertejuk@mwcis.com> also reports 535 that cfsd (ports/security/cfs) needs to be recompiled after 536 these changes are installed. 537 538 ****************************DANGER******************************* 539 540 DO NOT make installworld after the buildworld w/o building and 541 installing a new kernel FIRST. You will be unable to build a 542 new kernel otherwise on a system with new binaries and an old 543 kernel. 544 54520031112: 546 Some netgraph string length constants have been changed. This 547 change requires the netgraph kernel modules and all netgraph 548 userland components to be in sync. Especially users who require 549 netgraph to boot need to make sure to have world and kernel in 550 sync before rebooting. 551 55220031111: 553 Hyperthreading logical CPU's are no longer probed by default 554 when using the MP Table. If ACPI is being used, then logical 555 CPUs will be probed if hyperthreading is enabled in the BIOS. 556 If ACPI is not being used and hyperthreading is enabled in the 557 BIOS, logical CPUs can be enabled by building a custom kernel 558 with the option MPTABLE_FORCE_HTT enabled. 559 56020031103: 561 The i386 APIC_IO kernel option has been replaced by 562 'device apic'. The ACPI module has also been temporarily 563 disabled, so ACPI must be statically compiled into your 564 kernel using 'device acpi' if you wish to use the ACPI driver. 565 56620031031: 567 The API and ABI of struct ifnet have been changed by removing 568 the if_name and if_unit members and replacing them with 569 if_xname, if_dname, and if_dunit. All network drivers and most 570 userland programs which include net/if_var.h must be updated 571 and recompiled. __FreeBSD_version has been bumped to 501113 to 572 reflect this change. 573 57420030928: 575 Changes to the cdevsw default functions have been made to remove 576 the need to specify nullopen() and nullclose() explicitly. 577 __FreeBSD_version bumped to 501110. 578 57920030926: 580 kiconv(3) has been added. mount_msdosfs(8), mount_ntfs(8) and 581 mount_cd9660(8) need to be in sync with kernel. 582 58320030925: 584 Configuring a system to use IPFILTER now requires that PFIL_HOOKS 585 also be explicitly configured. Previously this dependency was 586 magically handled through some cruft in net/pfil.h; but that has 587 been removed. Building a kernel with IPFILTER but not PFIL_HOOKS 588 will fail with obtuse errors in ip_fil.c. 589 59020030923: 591 Fix a bug in arplookup(), whereby a hostile party on a locally 592 attached network could exhaust kernel memory, and cause a system 593 panic, by sending a flood of spoofed ARP requests. See 594 FreeBSD-SA-03:14.arp. 595 59620030915: 597 A change to /etc/defaults/rc.conf now causes inetd to be started 598 with `-C 60' if it is not overridden in /etc/rc.conf. This 599 causes inetd to stop accepting connections from an IP address 600 that exceeds the rate of 60 connections per minute. 601 60220030829: 603 The following rc.d scripts have been removed and should be 604 deleted from your installation: atm2.sh atm3.sh devdb 605 localdaemons network1 network2 network3. Depending on when 606 you last updated world and used mergemaster(8) you may or 607 may not have problems during the rc boot sequence. The simplest 608 solution is an 'rm -rf /etc/rc.d/*' and then 'mergemaster -i'. 609 The atm2.sh atm3.sh and devdb scripts were removed some time 610 ago, so depending on when you installed -CURRENT these scripts 611 may or may not exist on your system. 612 61320030824: 614 ATAng has been committed. You need to build world as sys/ata.h 615 has changed, and userland atacontrol depends on it. 616 If you use ATA SW raids you need "device ataraid" in your 617 kernel config file, as it is no longer pulled in automatically. 618 61920030819: 620 The OFW_NEWPCI option has been turned on in the Sparc64 GENERIC kernel. 621 Among other things, this changes the device enumeration to be 622 closer to Solaris. Be aware that, this can even cause the machine 623 to not boot without manual intervention before the fstab is adjusted. 624 62520030728: 626 All current USB and Firewire quirks in da(4) have been deprecated 627 and will be removed for 5.2. If this causes failure for your 628 umass(4) devices, enable "options DA_OLD_QUIRKS" in your kernel 629 and send the output of "camcontrol inquiry da0" to scsi@freebsd.org 630 so the quirk can be re-enabled. 631 63220030724: 633 Problems with entry 20030714 have been corrected and no known issues 634 with /rescue and -j exist for host systems after this point in time. 635 63620030722: 637 FPU-less support has been removed from FreeBSD. Chances are you won't 638 notice. 386+387 support should still work after this change, but 639 it is now a minimum requirement for the i386 port that you have real 640 FPU hardware. 641 64220030714: 643 Some people are having problems with changes related to /rescue. 644 If you are building -j N, you will need to define NO_RESCUE. Others 645 will need to define it if /rescue has issues with their environment. 646 People should report those issues to current@. 647 64820030711: 649 gcc was upgraded to 3.3. You are advised to not build -DNOCLEAN 650 across this point. Further, it might be a good idea to remove 651 /usr/obj. 652 65320030610: 654 Remove deprecated locale names and transition period code 655 for them, finishing switching to the new scheme. Check your 656 LANG environment variable. 657 65820030609: 659 CCD has been changed to be a fully GEOMified class. Kernel 660 and ccdconfig(8) needs to be in sync, this is particularly 661 important to remember beforehand if your source tree is on 662 a ccd device. Consider making a copy of the old ccdconfig 663 into /boot/kernel.good or wherever you keep your backup 664 kernel. 665 66620030605: 667 There was a small window in which sed(1) was broken. If you 668 happen to have sed(1) installed during that window, which is 669 evidenced by an inability to build world with the failure 670 given below, you need to manually build and install sed(1) 671 (and only sed(1)) before doing anything else. This is a one- 672 time snafu. Typical failure mode: 673 674 In file included from /usr/src/contrib/binutils/bfd/targets.c:1092: 675 targmatch.h:7:1: null character(s) ignored 676 targmatch.h:12:1: null character(s) ignored 677 targmatch.h:16:1: null character(s) ignored 678 : 679 680 The window of "sed(1)-uction" is from Wed Jun 4 15:31:55 2003 UTC 681 to Thu Jun 5 12:10:19 2003 UTC (from rev 1.30 to rev 1.31 of 682 usr.bin/sed/process.c). 683 68420030505: 685 Kerberos 5 (Heimdal) is now built by default. Setting 686 MAKE_KERBEROS5 no longer has any effect. If you do NOT 687 want the "base" Kerberos 5, you need to set NO_KERBEROS. 688 68920030502: 690 groff has been updated. If you try to do a buildworld and 691 get an infinite loop in troff, update to May 4th or newer. If you 692 have a newer kernel than userland, you may need to set the OSRELDATE 693 to 500110 in your environment before starting a buildworld. 694 69520030501: 696 The old rc system has been removed. Please report any problems 697 to freebsd-rc@yahoogroups.com, and/or freebsd-current@freebsd.org. 698 Your personal versions of these files will not be removed, so you can 699 continue to use them. However, you should take great care when updating, 700 especially when using mergemaster, since the compatibility code that 701 utilizes these old scripts has also been removed. 702 70320030423: 704 A bug has been fixed in /dev/devctl which would cause devd 705 to hang on boot, were it not for a workaround in devd. The 706 work around in devd will be removed around 20030507. You 707 have until then to upgrade your kernel before updating 708 userland. In general, you should have a userland and 709 kernel that's in sync with each other. However, given the 710 effects of this bug (hang on boot when starting devd), some 711 allowances are made. 712 71320030329: 714 Alphas with libc from between 20030312 and 20030329 exhibit 715 floating point exceptions (FPEs), most notably in awk(1) 716 while upgrading the system through a buildworld. 717 718 So, to successfully upgrade your Alpha, you must either 719 downgrade your libc.so to a pre-20030312 version, or update 720 /usr/share/mk/bsd.cpu.mk to revision 1.26 which adds -mieee 721 to CFLAGS, then forcibly rebuild and install libc: 722 723 cd /usr/src/lib/libc && \ 724 make cleandir && make obj && \ 725 make -DNOMAN -DNOPROFILE all && \ 726 make -DNOMAN -DNOPROFILE install 727 72820030208: 729 sendmail 8.12.7 has been imported. It has one important 730 change for IPv6 users. The default submit.mc now uses 731 '[127.0.0.1]' instead of 'localhost' meaning only IPv4 is 732 used to connect to the MTA. Users on IPv6-only machines 733 will need to edit /etc/mail/submit.mc appropriately. 734 73520030128: 736 NODEVFS option has been removed and DEVFS thereby made standard. 737 This makes all references to MAKEDEV obsolete, and they should 738 be removed when convenient. 739 74020030126: 741 The name of the device for the ofw console has changed, sparc64 users 742 must run mergemaster to update their installed /etc/ttys. 743 74420030125: 745 The scheduler framework has grown a second scheduler and consequently 746 you must specify one and only one scheduler in your kernel config. 747 The cvs config files have been updated to use the old scheduler 748 which may be selected via 'options SCHED_4BSD'. If you would like 749 to try the new, much more experimental, scheduler please try 750 'options SCHED_ULE' and contribute to the arch@ discussion. 751 75220030115: 753 A new version of the wi driver has been imported into the tree. 754 One now must have device wlan in the config file for it to operate 755 properly. 756 757 In addition, there have been some changes to how wi devices are 758 configured for point to point links to bring it more in line 759 with the former way of doing things, as well as compatibility 760 with NetBSD. 761 76220021222: 763 For a period after the GCC 3.2.1 import (from 12/04 to 12/22), GCC 764 used an incompatible form of ABI for returning structures and unions 765 which FreeBSD's GCC maintainers were not aware of relative to previous 766 versions of FreeBSD. We have gone back to the ABI for now, and any 767 code compiled which is required to interoperate with other code (not 768 built at the same time) returning structs or unions should be 769 rebuilt. 770 77120021216: 772 A name change in /etc/netconfig has been reverted to stay 773 compatible with suns TIRPC and also with NetBSD. You need 774 to run mergemaster after make world. A new libc does still work 775 with an outdated /etc/netconfig for some time, but you'll get 776 a warning. This warning will be removed in 20030301. 777 77820021202: 779 The recent binutils upgrade marks a kernel flag day on 780 sparc64: modules built with the old binutils will not work 781 with new kernels and vice versa. Mismatches will result in 782 panics. Make sure your kernel and modules are in sync. 783 78420021029: 785 The value of IPPROTO_DIVERT has changed. Make sure to keep 786 your kernel, netstat, natd and any third-party DIVERT 787 consumers in sync. 788 78920021024: 790 Old, compatibility slices have been removed in GEOM kernels. 791 This means that you will have to update your /etc/fstab to 792 not use disk devices of the form /dev/ad0a. Instead, you 793 now must specify /dev/ad0s1a, or whatever slice your FreeBSD 794 partition really is on. The old device names have gone 795 away, so if you use them anywhere else, you must also adjust 796 those uses. (This doesn't affect the disks formatted in 797 the ``dangerously-dedicated'' mode.) 798 79920021023: 800 Alphas with kernels from between 20020830 and 20021023 and/or 801 rtld (ld-elf.so.1) older than 20021023 may experience problems 802 with groff while doing a buildworld (kernel: "out of memory", 803 fixed in rev 1.129 of kern/imgact_elf.c; rtld: "too few PT_LOAD 804 segments", fixed in rev 1.8 of libexec/rtld-elf/map_object.c). 805 806 So, to successfully upgrade your Alpha, you must either 807 upgrade your kernel and rtld first (which might be a bit 808 tricky), or avoid running the bootstrapped groff during the 809 "transitional" buildworld. To avoid running groff during the 810 transitional upgrade run make buildworld with -DNOMAN, 811 -DNO_SHAREDOCS, and -DNO_LPR. 812 81320020831: 814 gcc has been upgraded to 3.2. It is not all binary compatible 815 with earlier versions of gcc for c++ programs. All c++ 816 programs and libraries need to be recompiled. 817 818 Also, if you encounter g++ issues, rm /usr/include/g++/* before 819 doing an installworld to make sure that stale files are removed. 820 82120020827: 822 Our /etc/termcap now has all the entries from the XFree86 xterm 823 almost unchanged. This means xterm now supports color by default. 824 If you used TERM=xterm-color in the past you now should use 825 TERM=xterm. (xterm-color will lead to benign warnings). 826 82720020815: 828 A "bug" in gcc(1) that was hiding warning in system headers was 829 fixed. It's probably time to add -DNO_WERROR to your make line 830 again. 831 83220020729: 833 COPY is being deprecated. The 20010530 change was reverted, as 834 it causes far more pain than was expected, and to always compare 835 before installing, please use INSTALL="install -C" again. The 836 -C option is now silently ignored when used with the -d option. 837 83820020702: 839 Problems with libc_r clients like KDE and GNOME have been resolved. 840 There are still some minor problems with some signals but the 841 system is stable enough for general use again. SMP is less so than UP 842 but each can successfully complete multiple buildworlds. 843 Libkvm needs to be recompiled due to KSE. 844 84520020701: 846 Now would be a bad time to upgrade. Something in or near the 847 KSE commit totally broke programs using libc_r like KDE and 848 GNOME. 849 85020020511: 851 The k5su utility installed as part of Kerberos 5 is no longer 852 installed with the set-user-ID bit set by default. Add 853 ENABLE_SUID_K5SU=yes to /etc/make.conf to have it installed 854 with the set-user-ID bit set. 855 85620020510: 857 Gcc 3.1 debugging format (cc -g) has changed from STABS to DWARF2. 858 Unfortunately our native GDB (at version 4.18) does not understand 859 the DWARF2 debugging format. Thus you must use `gcc -gstabs+' to 860 generated debugging information for our native GDB. 861 86220020510: 863 Due to the way CVS works, it may not properly update src/contrib/gcc 864 to the 3.1 sources. The easiest fix is to `rm -rf' src/contrib/gcc 865 and then do a cvs update. 866 86720020421: 868 When exec'ing set[ug]id executables, the kernel now ensures that the 869 stdio file descriptors (0..2) are open. See FreeBSD-SA-02:23.stdio. 870 87120020404: 872 New sendmail startup scripts have been installed to make it 873 easier to use alternative MTAs with FreeBSD. Setting the rc.conf 874 variable sendmail_enable to "NO" no longer prevents any sendmail 875 daemons from starting. Instead, either set sendmail_enable to 876 "NONE" or change mta_start_script to a script for starting 877 an alternative MTA. Setting mta_start_script to "" will 878 also prevent any MTA from being started at boot. 879 88020020403: 881 UCONSOLE is no longer a valid kernel option. 882 88320020315: 884 FreeBSD 5.0 DP-1 was basically branched today. 885 88620020225: 887 Warnings are now errors in the kernel. Unless you are a developer, 888 you should add -DNO_WERROR to your make line. 889 89020020217: 891 sendmail 8.12.2 has been imported. The sendmail binary is no 892 longer a set-user-ID root binary and the infrastructure to support 893 command line mail submission has changed. Be sure to run 894 mergemaster (especially for updating /etc/rc, /etc/defaults/rc.conf, 895 and /etc/mail) and read /etc/mail/README for more details. 896 897 Due to the import of sendmail 8.12.2, a new user and group are 898 required in order for sendmail to run as a set-group-ID 899 binary. A 'make installworld' will use the new user and group 900 to set the owner and group of /var/spool/clientmqueue and will 901 fail if the new user and group do not exist. The 'smmsp' user 902 and group must be merged from src/etc/group and 903 src/etc/master.passwd before using 'make installworld'. 904 'mergemaster -p' will do this. You may need to install 905 mergemaster before this will work if you are updating from a 906 very old version of current. The updating recipe has changed 907 as of this date. 908 90920020112: 910 The preferred configuration method for PAM is now /etc/pam.d/ 911 rather than /etc/pam.conf. If you have an unmodified 912 pam.conf, just delete it after your next mergemaster run. If 913 you have local modifications, you can use 914 /usr/src/etc/pam.d/convert.pl to incorporate them into your 915 /etc/pam.d. 916 917 Please see the following url for more details: 918http://www.freebsd.org/cgi/mid.cgi?db=mid&id=<xzp6667fyoa.fsf@flood.ping.uio.no> 91920011229: 920 If anyone here is already using the new rc.conf(5) variable 921 networkfs_types, please note that it has changed 922http://www.freebsd.org/cgi/mid.cgi?db=mid&id=<9744.1009655556@axl.seasidesoftware.co.za> 923 92420011220: 925 sys/i4b/driver/i4b_ispppsubr.c has been retired. This file 926 started out its life in the ISDN4BSD project as an offspring 927 from sys/net/if_spppsubr.c, which eventually got a life of its 928 own. All the accumulated features and bug fixes of the i4b 929 version have now been merged back into the base system's 930 version now. The only user-visible change resulting from this 931 is that i4b's sppp(4) interfaces are to be managed with 932 spppcontrol(8) again, since ispppcontrol(8) has been retired 933 as well. (There has never been rc file support for 934 ispppcontrol in -current, but only in -stable. That will be 935 reverted by the time the changes are MFCed.) 936 93720011215: 938 The fdc(4) driver has been updated and now automatically 939 recognizes media in `standard' formats (like 1440 KB and 940 720 KB for a 3.5" high-density drive) when accessing the 941 default device node (e. g. /dev/fd0). The old variety of 942 floppy device nodes /dev/fd*.* is no longer present by 943 default, devices can be created (in DEVFS) on demand. They 944 will need to be customized then for `odd' densities using 945 fdcontrol(8). 946 94720011209: 948 The bugs in procfs' debugging support code have been fixed, 949 and truss(1) now works again. 950 95120011207: 952 Daily security checks have been split out to use the periodic(8) 953 scripts. Some change in configuration may be necessary. Please 954 see 955http://www.freebsd.org/cgi/mid.cgi?db=mid&id=<20011207155805.R8975@blossom.cjclark.org> 956 for details. 957 95820011204: 959 sos added VCD/SVCD support to ata driver and that needs the 960 kernel and burncd to be in sync. 961 96220011203: 963 The procfs pseudo-filesystem has now been converted to use the 964 pseudofs framework. If you have 'options PROCFS' in your 965 kernel config, you'll need to add 'options PSEUDOFS' if it's 966 not there already. 967 968 This change temporarily breaks truss(1); use ktrace(1) instead 969 until the issue has been resolved. 970 97120011202: 972 A security hole in OpenSSH involving `UseLogin yes' has been 973 patched. 974 97520011126: 976 You need to remove /usr/obj/.../usr.bin/tip before rebuilding 977 after this date. You need to do this only once. 978 97920011103: 980 Most of the awk issues have been resolved. Some rough 981 edges may be left, but for the most part things should be 982 back to "normal." For CURRENT's usual definition of "normal." 983 98420011030: 985 Awk has been upgraded to the one true awk from bell labs. Expect 986 choppy waves in the upgrade process. 987 98820011030: 989 The asr driver problem has been resolved. 990 99120011027: 992 Due to changes in other parts of the system, the asr driver 993 now causes the system to panic on boot. Do not use it pending 994 correction. Comment it out of any kernel config file that you 995 try to use from this date forward. 996 99720011025: 998 When crossbuilding, use TARGET=xxx where you used to use 999 MACHINE=xxx. You don't need to set TARGET_ARCH and TARGET, 1000 unless you are changing both of them. To cross build pc98 on 1001 an alpha, for example, you need to set TARGET=pc98 and 1002 TARGET_ARCH=i386. 1003 100420011001: 1005 The kernel interface that burncd depends on has changed. 1006 You must recompile both the kernel and userland applications 1007 at the same time. 1008 100920010929: 1010 When crossbuilding, please set TARGET_ARCH rather than 1011 MACHINE_ARCH to indicate the target. In the future, one will 1012 set TARGET_MACHINE where you set MACHINE now. At the moment, 1013 setting MACHINE alone for same MACHINE_ARCH machines works 1014 (eg, you can build pc98 on an i386 machine and vice versa). 1015 101620010927: 1017 Some weird problems result from using ACPI on some machines. 1018 To disable ACPI you can add 1019 hint.acpi.0.disabled="1" 1020 to /boot/loader.conf (or by putting set X=Y at the boot 1021 loader "ok" prompt). 1022 1023 Alternatively, you can remove it from /boot/kernel/acpi.ko 1024 or use the MODULES_OVERRIDE function in your kernel config 1025 file and not list acpi in that list. 1026 102720010924: 1028 The buildworld has been fixed. You may need to install 1029 the 4.x compatibility libraries for some old binaries 1030 to work. Add COMPAT4X=true to your /etc/make.conf to 1031 get them installed on every installworld, or execute the 1032 following to get them installed only once: 1033 cd src/lib/compat/compat4x.<arch> 1034 make all install 1035 You will see ``__stdoutp undefined'' until you do this. 1036 103720010919: 1038 There's a bug in the world build process. The cross-tools 1039 are build with the NEW headers, but the OLD libc.a. This 1040 leads to all kinds of problems with the new libc. A temporary 1041 workaround is to add 1042 CFLAGS="-O -pipe -D_OLD_STDIO" 1043 before building world when upgrading from 4.x to current. This 1044 can be removed afterwards. 1045 1046 A proper fix to the buildworld target is needed. 1047 104820010918: 1049 Peter has committed his new kthread nfs client/server code. 1050 NFS may be unstable after this date. 1051 105220010912: 1053 KSE has hit the tree. Lots of things are now different in 1054 the kernel. While a few problems were introduced in the 1055 initial commit, most of the major ones have been found and 1056 corrected. 1057 105820010901: 1059 In OLDCARD, CardBus bridges appear to be stable. The work 1060 arounds described in the 20010604 entry are now no longer 1061 necessary and will be ignored. Most insert/remove problems 1062 have been rectified around this date. 1063 106420010823: 1065 named now runs as user bind and group bind rather than as 1066 root. If named_enable is set to YES in /etc/rc.conf, ensure 1067 that user bind is available in /etc/passwd (using vipw(8)) 1068 and that group bind is available in /etc/group. Also make 1069 sure that user or group bind has read (and not write) 1070 permission for your name server configuration and that it 1071 has read and write permission for your slave zone files and 1072 directory. 1073 1074 If you wish to continue to run named as root (a less secure 1075 alternative), add a line to /etc/rc.conf saying 1076 1077 named_flags= 1078 107920010709: 1080 The PAM libraries have had an API upgrade that is beyond 1081 the ability of the shared library major number to handle. 1082 It is manifested by PAM-using ports dumping core. The 1083 solution is to rebuild those ports. 1084 108520010628: 1086 The kernel compile module has moved from src/sys/compile/FOO 1087 to src/sys/${MACHINE}/compile/FOO. 1088 108920010625: 1090 The pccard modem issue from 20010613 has been corrected. 1091 OLDCARD support is still a little weak in -current. slot 1 is 1092 known not to work on some TI based cardbus bridges. Some 1093 cardbus bridges do not properly detect insert/removal events. 1094 IRQ configuration needs more safety belts. 1095 109620010617: 1097 Softupdates problems have been corrected. 1098 109920010614: 1100 Peter ripped out the linkerset support. You must, as always, 1101 rerun config after you cvsup if you are using the traditional 1102 kernel building methods. 1103 110420010613: 1105 pccard modems may not work with current after 20010604 date. Some 1106 do, others result in panics. *MAKE*SURE* that you update your 1107 config and /etc/rc.conf ala the 20010604 entry, or you will have 1108 problems (this issue will be fixed, it just hasn't been yet). 1109 111020010613: 1111 SOFTUPDATES seem to be broken since the middle of May or so. Do not 1112 use them in current. You can disable softupdates on all mounted 1113 partitions, or remove SOFTUPDATES the kernel config file. 1114 111520010612: 1116 After Peter's commits to the hints code, people have been noticing 1117 that certain devices are attached (or try to) twice. This is due 1118 to having both static hints as well as a /boot/device.hints. To 1119 work around this issue, please use only one or the other mechanism 1120 until this bug is fixed. 1121 1122 Please note that a feature of config is that if you have config 1123 file FOO and FOO.hints, it automatically adds FOO.hints to the 1124 hints.c file, whether you want it to or not. 1125 112620010610: 1127 Locale names have changed to match other systems better. 1128 112920010604: 1130 pccard support for pci cards has been committed. You must change 1131 your /etc/pccard.conf irq lines. It must match the irq used by 1132 pcic device. Interrupt storms may result if you fail to do this. 1133 Interrupt storms look a lot like a hang. 1134 1135 You must also install a new pccardd, otherwise you will get an 1136 interrupt storm at card reset time (just after it tells you what 1137 it is). 1138 1139 pccardd_flags="-I" is necessary for the time being. It tells pccardd 1140 not to ask the kernel if the interrupt is really free or not before 1141 using it. You can either change the /etc/pccard.conf irq lines to 1142 match pcic, or add "-i X" to the pccardd_flags. 1143 114420010530: 1145 INSTALL=install -C is being deprecated. If you want to do this, 1146 use COPY=-C instead. The former method will be supported for only 1147 a limited time. If you see 1148 1149install: warning: the -d and -C options may not be specified together 1150 1151 in your makeworld, then you need to migrate towards using 1152 COPY=-C. 1153 115420010525: 1155 It appears that vm is now stable enough to use again. However, 1156 there may be other problems, so caution is still urged. alpha 1157 definitely is in bad shape. 1158 115920010521: 1160 Minor repo damage has happened. This may cause problems 1161 with cvsup of ports. If you get errors, please see 1162 http://www.FreeBSD.org/cgi/query-pr.cgi?pr=27495 1163 at the bottom for details on a workaround. The error message 1164 is 1165Updater failed: Cannot delete "/usr/ports/www/jakarta-tomcat/files": Directory not empty 1166 116720010520: 1168 Vm and/or swapping are busted on -current. Please be patient. 1169 117020010519: 1171 pccard has had much reorganizational work done to it over 1172 the past few days. Everything should still work, but if 1173 not, please contact imp@freebsd.org. 1174 117520010517: 1176 ata ioctl changed. Make sure to recompile both kernel and 1177 userland at the same time. 1178 117920010517: 1180 New ncurses imported. 1181 118220010512: 1183 DEVFS is now opt out, not opt in. Barring major problems, this 1184 will be the only way to go starting July 1. 1185 118620010504: 1187 OpenSSH has been updated to 2.9. Some defaults are different, 1188 including RhostsRSAAuthentication, which changes from yes to no. 1189 119020010502: 1191 Perl breakage in 20010501 was corrected at 14:18:33 PDT. 1192 119320010501: 1194 Building perl was broken at 02:25:25 PDT. 1195 119620010430: 1197 The bug in 20010429 was corrected at 07:35:37 PDT. It is safe to 1198 go back in the water. 1199 120020010429: 1201 A bad bug was committed at 04:48:42 PDT. Don't use kernels after 1202 this date, but before the correction date. 1203 120420010423: 1205 old fsck and new kernel interactions appear to have been fixed. 1206 120720010411: 1208 fsck and the kernel were changed to handle some optimizations 1209 to directory layout. This breaks backward compatibility. 1210 Update only if you understand that you must not use the old 1211 fsck with the new kernel ever. 1212 121320010330: 1214 fsck has changed the meaning of the pass column in /etc/fstab. 1215 Please see the cvs commit to fsck.8 or the fsck.8 man page for 1216 details. It is unclear if changes to /etc/fstab are necessary. 1217 121820010319: 1219 portmap had changed name to rpcbind for maximum POLA in your 1220 current world. /etc/hosts.{allow,deny} needs changes. nfs and 1221 other rpc based programs that rely on portmapper will not work 1222 without updates to /etc/hosts.{allow,deny} and /etc/netconfig. 1223 122420010315: 1225 ata subsystem changes. ATA_ENABLE_ATAPI_DMA, ATA_ENABLE_WC 1226 and ATA_ENABLE_TAGS are no longer kernel options. They have 1227 been replaced by tunables. See ata.4 for details. 1228 122920010312: 1230 The fxp driver was converted to use miibus. If you compile 1231 fxp into your kernel statically, you will need to add miibus. 1232 123320010312: 1234 The wi device now defaults to BSS (infrastructure) mode 1235 instead of ad-hoc. 1236 123720010310: 1238 /dev/urandom should be a symbolic link to /dev/random now. 1239 Users of current not using DEVFS need to run MAKEDEV std. 1240 ssh might not work if you don't. 1241 124220010303: 1243 The ed driver has been updated. It now allows mii attachments, 1244 which means that you must include the miibus in your kernel if 1245 you use the ed driver. 1246 124720010220: 1248 The problems with libc have been corrected. It is now mostly 1249 safe to go back into the water. 1250 125120010211: 1252 The size of FILE was changed. This breaks upgrading. If 1253 you must upgrade, be prepared for pain. It also breaks almost 1254 all binaries that you've compiled on -current. You are warned 1255 that before upgrading would be a good time to do a level 0 1256 dump of your system. No, really, I mean it this time. 1257 1258 To get to the new system, you'll need to use the following 1259 workaround. Hopefully this can be sorted out so that we 1260 don't have to move this to the updating section. 1261 1262 To get around the installworld problem, do: 1263 # cd /usr/src/usr.bin/sed 1264 # make install 1265 # cd /usr/src 1266 # make installworld 1267 If that doesn't work, then try: 1268 # make -k installworld 1269 # make installworld 1270 127120010207: 1272 DEVFS is now the default. If you use vinum, make sure that you 1273 do not include devfs in your kernel as problems result. 1274 127520010205: 1276 FFS_ROOT and CD9660_ROOT have been removed or deprecated. 1277 Remove them from your config. 1278 127920010122: 1280 ****************************** WARNING ****************************** 1281 buildkernel has been changed slightly 1282 ****************************** WARNING ****************************** 1283 KERNCONF replaces the variable KERNEL for buildkernel. You 1284 should update your scripts and make.conf accordingly. 1285 128620010119: 1287 config has changed to allow DEV_FOO as a replacement for NFOO. 1288 This requires a new config to build correctly. 1289 129020010116: 1291 The kernel option I386_CPU is now mutually exclusive with the 1292 other cpu types. If you have an i386 system, be sure that it 1293 only had this line. Remove it for all other configurations. 1294 129520010110: 1296 Changes to the kernel require it and burncd be in sync. 1297 129820010102: 1299 Everyone who has hw.sndunit set to something in 1300 /etc/sysctl.conf, it is now hw.snd.unit. 1301 130220010101: 1303 ex and vi were broken by some changes to sys/queue.h. If you 1304 have a bad vi, you will see make buildworld fail with a core 1305 dump while building termcap. You can work around this problem 1306 by adding -k to your make buildworld. This will cause the 1307 build to complete and install a new vi. Once that's done, you 1308 can rebuild again without the -k to pick up anything that 1309 might have been ignored by the -k option. 1310 1311 Others have suggested that you can just rebuild libc if your 1312 vi/ex is dynamically linked, but I've not received any reports 1313 of this working. 1314 131520001228: 1316 There have been some changes to libcrypt in -current. The 1317 libscrypt/libdescrypt symlink silliness is gone and the installed 1318 libcrypt is fully functional. Be aware of this. 1319 132020001218: 1321 Linksys Fast Ethernet PCCARD cards supported by the ed driver 1322 now require the addition of flag 0x80000 to their config line 1323 in pccard.conf(5). This flag is not optional. These Linksys 1324 cards will not be recognized without it. 1325 132620001205: 1327 Important new FreeBSD-version stuff: PAM support has been worked 1328 in, partially from the "Unix" OpenSSH version. This requires 1329 adding the following in pam.conf: 1330 1331 sshd auth sufficient pam_skey.so 1332 sshd auth required pam_unix.so try_first_pass 1333 sshd session required pam_permit.so 1334 133520001031: 1336 cvs updated to 1.11. 1337 133820001020: 1339 The random device needs more entropy, so you need to make sure 1340 that you've run mergemaster to get a /etc/rc which will seed 1341 /dev/random. If you don't and the system hangs after ldconfig, 1342 then banging on the keyboard randomly until it unhangs is one 1343 workaround. 1344 134520001010: 1346 ****************************** WARNING ****************************** 1347 Sendmail has been updated. 1348 ****************************** WARNING ****************************** 1349 o mail.local(8) is no longer installed as a set-user-id binary. 1350 o sendmail(8) is now built with STARTTLS support unless NO_OPENSSL 1351 is set. 1352 o The default /etc/mail/sendmail.cf disables the SMTP EXPN and VRFY 1353 commands. 1354 o Now using sendmail's version of vacation(1). 1355 o The sendmail cf building tools (contrib/sendmail/cf) are installed 1356 in /usr/share/sendmail/cf. 1357 o sendmail.cw changed to local-host-names 1358 1359 More details can be found at 1360 http://people.freebsd.org/~imp/UPDATING/sendmail-20001010 1361 136220001009: 1363 The ports tree's new layout is in place. Be sure to update 1364 your entire ports tree, or you will have problems. 1365 136620001006: 1367 The perl build procedure no longer installs miniperl, nor uses 1368 the installed miniperl. It is recommended that you delete 1369 /usr/bin/miniperl. 1370 137120001005: 1372 This weekend the ports tree will be updated to a new layout. 1373 It will be in an inconsistent state until noted in the UPDATING 1374 file, or with asami-san's message to the relevant mailing 1375 lists. With this new layout, you'll need to update the whole 1376 tree for anything to work. 1377 137820000928: 1379 There was a change in the passwd format. Need more information. 1380 138120000916: 1382 /boot/kernel/kernel.ko -> /boot/kernel/kernel change has taken 1383 place. Please update boot loader (not the boot blocks) at the 1384 same time as your kernel. 1385 138620000914: 1387 The new pmtimer device is necessary for laptops. Failure to 1388 include the device will cause suspended laptops losing time 1389 when they resume. Include 1390 device pmtimer 1391 in your config file and 1392 hint.pmtimer.0.at="isa" 1393 to your /boot/device.hints file. 1394 139520000911: 1396 The random device has been turned into a (pseudo-)device, 1397 rather than an option. The supplied kernel config files have 1398 been updated. You will need to do something similar in your 1399 own kernel config file. 1400 Remove: 1401 options RANDOMDEV 1402 Add: 1403 device random 1404 If you prefer to load the loadable module, you need to do 1405 nothing. 1406 140720000909: 1408 The random device module has been renamed from randomdev.ko to 1409 random.ko. You will need to edit your /boot/loader.conf to 1410 reflect this if you load this module at boot time. 1411 The line should read: 1412 random_load="YES" 1413 141420000907: 1415 The SMPNG commit has happened. It should work, but if it 1416 doesn't, fallback to the PRE_SMPNG CVS tag. There are likely 1417 to be a variety of minor issues. Please see 20000905 to make 1418 sure you don't have model loading problems which might at 1419 first blush appear related to SMP. 1420 142120000906: 1422 nsswitch has been imported from NetBSD. Among other things, 1423 this means that /etc/host.conf is no longer used. See 1424 nsswitch.conf(5) instead. Note that at boot time rc.network 1425 will attempt to produce a new nsswitch.conf file for you if you 1426 don't have one, and you have host.conf. 1427 142820000905: 1429 The ucred structure changed size. This breaks the interface 1430 that mountd uses. Trying to use an older mountd with a newer 1431 kernel guarantees a panic. This means that you need to use 1432 kernels newer than today only with matching mountd, but you 1433 needed to do that anyway with the boot loader changes. 1434 143520000905: 1436 The boot loader has been updated. The new default kernel is 1437 now /boot/kernel/kernel.ko. The new default module location 1438 is /boot/kernel. 1439 1440 You *MUST* upgrade your boot loader and kernel at the same time. 1441 The easiest way to do this is to do the buildworld/buildkernel/ 1442 installkernel/installworld dance. 1443 1444 Furthermore, you are urged to delete your old /modules directory 1445 before booting the new kernel, since kldload will find stale 1446 modules in that directory instead of finding them in the correct 1447 path, /boot/kernel. The most common complaint that this cures 1448 is that the linux module crashes your machine after the update. 1449 1450 if [ ! -d /boot/kernel.old ]; then 1451 mv /modules.old /boot/kernel.old 1452 chflags noschg /kernel.old 1453 mv /kernel.old /boot/kernel.old/kernel.ko 1454 chflags schg /boot/kernel.old/kernel.ko 1455 fi 1456 145720000904: 1458 A new issue with the sendmail upgrade has come to light. 1459 /etc/aliases has moved to /etc/mail/aliases. Mergemaster will 1460 incorrectly install the default aliases in /etc/mail rather than 1461 move the old one from /etc. So you'll need to manually move the 1462 file, create a symbolic link, remove the old /etc/aliases.db and 1463 run newaliases. For safety sake, you should stop sendmail 1464 while doing this and run the upgrade when locally sourced email 1465 is not likely to be generated. 1466 146720000825: 1468 /boot/device.hints is now required for installkernel to 1469 succeed. You should copy GENERIC.hints for your architecture 1470 into /boot/device.hints. If and only if you compile hints 1471 into your kernel, then this file may be empty. Please note, 1472 if you have an empty or missing /boot/device.hints file and 1473 you neglected to compile hints into your kernel, no boot 1474 messages will appear after the boot loader tries to start the 1475 kernel. 1476 147720000821: 1478 If you do NOT have ``options RANDOMDEV'' in your kernel and 1479 you DO want the random device then add randomdev_load="YES" to 1480 /boot/loader.conf. 1481 148220000812: 1483 suidperl is now always built and installed on the system, but 1484 with permissions of 511. If you have applications that use 1485 this program, you are now required to add ENABLE_SUIDPERL=true 1486 to /etc/make.conf. If you forget to do this, 1487 chmod 4511 /usr/bin/suidperl 1488 will fix this until the next build. 1489 149020000812: 1491 sendmail has been updated from 8.9.3 to 8.11.0. Some of the more 1492 visible changes that may immediately affect your configuration 1493 include: 1494 - New default file locations from src/contrib/sendmail/cf/README 1495 - newaliases limited to root and trusted users 1496 - MSA port (587) turned on by default 1497 - New queue file naming system so can't go from 8.11 -> 8.9 1498 - FEATURE(`rbl') renamed to FEATURE(`dnsbl') 1499 - FEATURE(`nullclient') is more full featured 1500 - FEATURE(`nouucp') requires an argument: `reject' or `nospecial' 1501 - mail.local FreeBSD-only -b option changed to -B 1502 - See src/contrib/sendmail/RELEASE_NOTES for more info 1503 150420000810: 1505 suidperl (aka sperl) is no longer build by default. You must 1506 specifically define BUILD_SUIDPERL to "true" for it to be build. 1507 Furthermore, we recommend that you remove /usr/bin/sperl* and 1508 /usr/bin/suidperl files from your system unless you have a 1509 specific use for it. 1510 151120000729: 1512 Networking defaults have been tightened. Anybody upgrading 1513 /etc/defaults/rc.conf needs to add the following lines to 1514 /etc/rc.conf if they want to have the same setup 1515 afterwards (unless the variables already are set, of course): 1516 # Enable network daemons for user convenience. 1517 inetd_enable="YES" 1518 portmap_enable="YES" 1519 sendmail_enable="YES" 1520 152120000728: 1522 If you have null_load="YES" in your /boot/loader.conf, you 1523 will need to change that to nullfs_load="YES". 1524 152520000728: 1526 The "installkernel" target has changed slightly. Now even if 1527 you override KERNEL e.g. 'make installkernel KERNEL=MYKERNEL' 1528 it will install the MYKERNEL file (built with the buildkernel 1529 target) as /kernel rather than /MYKERNEL. Those who have 1530 updated their /boot/loader.conf files to point to /MYKERNEL 1531 should remove that entry or perform manual rename of /kernel 1532 to /MYKERNEL. 1533 153420000711: 1535 If you use CVSUP or CTM to get CVS trees, AND you used to get 1536 the old crypto files from internat.freebsd.org AND you check 1537 out files from the CVS tree with the cvs command, please read 1538 http://people.freebsd.org/~imp/internat.txt 1539 for details on potential problems that you might have and how 1540 to get around them. 1541 1542 If you are merely a mirror, or don't answer yes to each of the 1543 clauses above, you needn't worry. 1544 154520000711: 1546 /etc/security has been updated to print the inode number of 1547 setuid programs that have changed. You will see a large spike 1548 in the number of changed programs the first time when you run 1549 mergemaster to get a new /etc/security. 1550 155120000710: 1552 /dev/random now has good entropy collection (from the keyboard 1553 and sysmouse drivers). Please ensure that either `options 1554 RANDOMDEV' is present in your kernel config file or that 1555 `randomdev_load="YES"' is in your /boot/loader.conf. If you do 1556 not have the /dev/random driver, OpenSSL (and consequently 1557 lots of crypto tools (like SSH)) will fail with strange 1558 errors. (see below, 20000624). 1559 1560 FreeBSD-current is safe again to run Crypto. 1561 156220000709: 1563 phk made the malloc default options AJ. This may slow things 1564 down and uncover other latent bugs in the code. If you need to 1565 run at full speed, you can disable this by doing the following: 1566 ln -s aj /etc/malloc.conf 1567 156820000706: 1569 libftpio's version was accidentally bumped a few days ago. This 1570 has been corrected. You may need to remove /usr/lib/libftpio.so.6 1571 before doing your next buildworld/installworld pair. It certainly 1572 won't hurt to remove it before the update procedure. It will 1573 break fetch until a new one is built, but ftp can be used in the 1574 interim if needed. 1575 157620000705: 1577 The crypto packages have changed for the cvsup. This has been done 1578 in a backward compatible way, but the old packages will go away at 1579 some point in the future. Look at /usr/share/examples/cvsup for 1580 details. 1581 158220000704: 1583 With the new sys/modules/sound/drivers/*, you will need to 1584 set SYSDIR until you do an installworld after July 7th. 1585 158620000704: 1587 rc.shutdown and rc will now call the rc.d scripts with start 1588 or stop. This may cause some harmless warnings from older 1589 rc.d scripts that haven't been updated. 1590 159120000630: 1592 The libfetch based version of fetch has gone into the tree. 1593 Minor problems may result on some of the less popular sites, 1594 which should be reported to des@freebsd.org. 1595 159620000625: 1597 From approximately this date forward, one must have the crypto 1598 system installed in order to build the system and kernel. 1599 While not technically strictly true, one should treat it as 1600 required and grab the crypto bits. If you are grabbing CVS 1601 trees, src-all and cvs-crypto should be treated as if they 1602 were required. You should check with the latest collections 1603 to make sure that these haven't changed. 1604 160520000624: 1606 Mark Murray just committed the first parts of a cleanup of 1607 /dev/zero, et al. This is also cleaning up /dev/random. 1608 The entropy is disconnected, so DO NOT USE VERSIONS OF FREEBSD 1609 -CURRENT FROM THIS POINT to 2000710 for cryptographic services 1610 until Mark can merge in the fixes to this work in progress. 1611 openssh and openssl should not be used to generate keys from this 1612 date to the completion of the work. 1613 1614 If you must operate at this reduced level of security, add ' 1615 options RANDOMDEV' to your kernel or modload the randomdev 1616 module. You may also need to copy a new MAKEDEV to /dev and 1617 recreate the random and urandom devices. 1618 161920000622: 1620 The license on the softupdates is now a standard 2 clause 1621 BSD license. You may need to remove your symbolic links 1622 that used to be required when updating. 1623 162420000621: 1625 Scott Flatman <sf@aracnet.com> sent in a decent write-up on 1626 the config file update procedure. 1627 http://people.freebsd.org/~imp/config-upd.html 1628 NOTE: LINT is gone. It has been replaced with NOTES. NOTES 1629 isn't buildable. However, you can generate a LINT file: 1630 cd /sys/<ARCH>/conf && make LINT 1631 163220000620: 1633 Binutils 2.10 have hit the tree, or will shortly. As soon 1634 as they do, the problem noted in 20000522 will be resolved and 1635 that workaround will no longer be required. 1636 163720000615: 1638 phk removed the compatibility creation of wd devices in the 1639 ad driver. If you haven't done so already, you must update 1640 your fstab, etc to use the ad devices instead of the wd 1641 devices. 1642 1643 In addition, you'll need to update your boot blocks to a 1644 more modern version, if you haven't already done so. Modern 1645 here means 4.0 release or newer (although older releases 1646 may work). 1647 164820000612: 1649 Peter took an axe to config(8). Be sure that you read his mail 1650 on the topic before even thinking about updating. You will 1651 need to create a /boot/device.hints or add a hints directive 1652 to your config file to compile them in statically. The format 1653 of the config file has changed as well. Please see GENERIC or 1654 NEWCARD for examples of the new format. 1655 1656 Indirectly, this also breaks USERCONFIG. Unless a newer entry 1657 says that it has been fixed, assume that must use the hints mechanism 1658 in the loader if you need to use a machine with very old ISA cards 1659 in it. 1660 166120000522: 1662 A new set of binutils went into the tree today. Anybody 1663 building a kernel after this point is advised that they need 1664 to rebuild their binutils (or better yet do a 1665 buildworld/installworld) before building a new kernel. 1666 1667 Due to bugs in binutils, using malloc options (eg /etc/malloc.conf 1668 or MALLOC_OPTIONS env var) J will cause ld to dump core. It 1669 is recommended that you don't set this option until the problem 1670 is resolved. 1671 167220000513: 1673 The ethernet drivers were all updated to clean up the BPF handling. 1674 167520000510: 1676 The problems with boot blocks on the alphas have been corrected. 1677 This will require some care in updating alphas. A new libstand 1678 is requires for the boot blocks to build properly. 1679 168020000503: 1681 Recompile all kld modules. Proper version dependency info 1682 is now available. 1683 168420000502: 1685 Modules have been disconnected from the buildworld tree and 1686 connected to the kernel building instead. 1687 168820000427: 1689 You may need to build gperf 1690 cd /usr/src/gnu/usr.bin/gperf && make depend all install 1691 when upgrading from 4.0 -> current. The build system now uses 1692 an option only in -current. 1693 169420000417: 1695 The method that we brand ELF binaries has changed to be more 1696 acceptable to the binutils maintainers. You will need to 1697 rebrand your ELF binaries that aren't native. One problem 1698 binary is the Linux ldconfig. After your make world, but 1699 before you reboot, you'll need to issue: 1700 brandelf -t Linux /compat/linux/sbin/ldconfig 1701 if you have Linux compatibility enabled on your machine. 1702 170320000320: 1704 If you have really bad/marginal IDE drives, you may find they 1705 don't work well. Use pio mode instead. The easiest way to 1706 cope if you have a problem combination is to add: 1707 /sbin/sysctl hw.ata.ata_dma=0 1708 to the start of /etc/rc.conf. 1709 171020000319: 1711 The ISA and PCI compatibility shims have been connected to the 1712 options COMPAT_OLDISA and COMPAT_OLDPCI. If you are using old 1713 style PCI or ISA drivers (i.e. tx, voxware, etc.) you must 1714 include the appropriate option in your kernel config. Drivers 1715 using the shims should be updated or they won't ship with 1716 5.0-RELEASE, targeted for 2001. 1717 171820000318: 1719 We've entered the traditional post release dumping party. 1720 Large kernel changes are being committed and are in the 1721 works. It is important to keep the systems' klds and kernel 1722 in sync as kernel interfaces and structures are changing. 1723 Before reporting kernel panics, make sure that all modules 1724 that you are loading are up to date. 1725 172620000315: 1727 If you are upgrading from an older version of FreeBSD, you 1728 need to update your boot blocks as well. 'disklabel -B ad0' 1729 will do the trick. This isn't critical until you remove your 1730 wd device entries in /dev, at which point your system will not 1731 boot. 1732 173320000315: 1734 4.0 RELEASE shipped. Please see the 4.0 UPDATING file for how 1735 to upgrade to 4.0 from 3.x. 1736 1737COMMON ITEMS: 1738 1739 # NOTE: 5.x below applies to 6.0-currrent as well, for the 1740 # momemnt. 4.any -> 5.any upgrade support will remain in 1741 # place for 6.0 current, but after 5.3 RELEASE, the 4.any -> 1742 # 6.0-current upgrade path will require moving through 5.3 1743 # RELEASE or newer. 1744 1745 General Notes 1746 ------------- 1747 Avoid using make -j when upgrading. From time to time in the 1748 past there have been problems using -j with buildworld and/or 1749 installworld. This is especially true when upgrading between 1750 "distant" versions (eg one that cross a major release boundary 1751 or several minor releases, or when several months have passed 1752 on the -current branch). 1753 1754 Sometimes, obscure build problems are the result of environment 1755 poisoning. This can happen because the make utility reads its 1756 environment when searching for values for global variables. 1757 To run your build attempts in an "environmental clean room", 1758 prefix all make commands with 'env -i '. See the env(1) manual 1759 page for more details. 1760 1761 To build a kernel 1762 ----------------- 1763 If you are updating from a prior version of FreeBSD (even one just 1764 a few days old), you should follow this procedure. With a 1765 /usr/obj tree with a fresh buildworld, 1766 make -DALWAYS_CHECK_MAKE buildkernel KERNCONF=YOUR_KERNEL_HERE 1767 make -DALWAYS_CHECK_MAKE installkernel KERNCONF=YOUR_KERNEL_HERE 1768 1769 To just build a kernel when you know that it won't mess you up 1770 -------------------------------------------------------------- 1771 This assumes you are already running a 5.X system. Replace 1772 ${arch} with the architecture of your machine (e.g. "i386", 1773 "alpha", "amd64", "ia64", "pc98", "sparc64", etc). 1774 1775 cd src/sys/${arch}/conf 1776 config KERNEL_NAME_HERE 1777 cd ../compile/KERNEL_NAME_HERE 1778 make depend 1779 make 1780 make install 1781 1782 If this fails, go to the "To build a kernel" section. 1783 1784 To rebuild everything and install it on the current system. 1785 ----------------------------------------------------------- 1786 # Note: sometimes if you are running current you gotta do more than 1787 # is listed here if you are upgrading from a really old current. 1788 1789 <make sure you have good level 0 dumps> 1790 <maybe fix /etc/fstab> [7] 1791 make buildworld 1792 make kernel KERNCONF=YOUR_KERNEL_HERE 1793 [1] 1794 <reboot in single user> [3] 1795 src/etc/rc.d/preseedrandom [10] 1796 mergemaster -p [5] 1797 make installworld 1798 mergemaster [4] 1799 <reboot> 1800 1801 1802 To cross-install current onto a separate partition 1803 -------------------------------------------------- 1804 # In this approach we use a separate partition to hold 1805 # current's root, 'usr', and 'var' directories. A partition 1806 # holding "/", "/usr" and "/var" should be about 2GB in 1807 # size. 1808 1809 <make sure you have good level 0 dumps> 1810 <boot into -stable> 1811 make buildworld 1812 <maybe newfs current's root partition> 1813 <mount current's root partition on directory ${CURRENT_ROOT}> 1814 make installworld DESTDIR=${CURRENT_ROOT} 1815 make buildkernel KERNCONF=YOUR_KERNEL_HERE 1816 cp src/sys/${ARCH}/conf/GENERIC.hints \ 1817 ${CURRENT_ROOT}/boot/device.hints # as needed 1818 make installkernel KERNCONF=YOUR_KERNEL_HERE DESTDIR=${CURRENT_ROOT} 1819 cd src/etc; make distribution DESTDIR=${CURRENT_ROOT} # if newfs'd 1820 cp /etc/fstab ${CURRENT_ROOT}/etc/fstab # if newfs'd 1821 <edit ${CURRENT_ROOT}/etc/fstab to mount "/" from the correct partition> 1822 <reboot into current> 1823 <do a "native" rebuild/install as described in the previous section> 1824 <maybe install compatibility libraries from src/lib/compat> 1825 <reboot> 1826 1827 1828 To upgrade in-place from 4.x-stable to current 1829 ---------------------------------------------- 1830 # 5.x uses more space than 4.x. Also, the location of kernel 1831 # modules has changed. If you are installing 5.x onto a 4.x 1832 # system, you'll need about 30MB of free disk space on your / 1833 # partition. If you have less than this, you may encounter difficult 1834 # to back out of problems with this procedure. If /tmp is on 1835 # the / partition, you may want to completely remove all its content 1836 # before upgrading, as this can be a common source of shortage of 1837 # space on /. 1838 1839 <make sure you have good level 0 dumps> 1840 <maybe fix /etc/fstab> [7] 1841 make buildworld [9] 1842 cp sys/${MACHINE}/conf/GENERIC.hints /boot/device.hints [2] 1843 make kernel KERNCONF=YOUR_KERNEL_HERE [8] 1844 cd sys/boot ; make STRIP="" install [6] 1845 [1] 1846 <reboot in single user> [3] 1847 src/etc/rc.d/preseedrandom [10] 1848 mergemaster -p [5] 1849 rm -rf /usr/include/g++ 1850 make installworld 1851 mergemaster -i [4] 1852 <reboot> 1853 1854 Make sure that you've read the UPDATING file to understand the 1855 tweaks to various things you need. At this point in the life 1856 cycle of current, things change often and you are on your own 1857 to cope. The defaults can also change, so please read ALL of 1858 the UPDATING entries. 1859 1860 Also, if you are tracking -current, you must be subscribed to 1861 freebsd-current@freebsd.org. Make sure that before you update 1862 your sources that you have read and understood all the recent 1863 messages there. If in doubt, please track -stable which has 1864 much fewer pitfalls. 1865 1866 [1] If you have third party modules, such as vmware, you 1867 should disable them at this point so they don't crash your 1868 system on reboot. 1869 1870 [2] If you have legacy ISA devices, you may need to create 1871 your own device.hints to reflect your unique hardware 1872 configuration. 1873 1874 [3] From the bootblocks, boot -s, and then do 1875 fsck -p 1876 mount -u / 1877 mount -a 1878 cd src 1879 adjkerntz -i # if CMOS is wall time 1880 Also, when doing a major release upgrade, it is required that 1881 you boot into single user mode to do the installworld. 1882 For the 4.x -> 5.x upgrade, you will also see many messages about 1883 needing to recompile your userland. These are harmless and can 1884 be ignored while you proceed to the next step. 1885 1886 [4] Note: This step is non-optional. Failure to do this step 1887 can result in a significant reduction in the functionality of the 1888 system. Attempting to do it by hand is not recommended and those 1889 that pursue this avenue should read this file carefully, as well 1890 as the archives of freebsd-current and freebsd-hackers mailing lists 1891 for potential gotchas. 1892 1893 [5] Usually this step is a noop. However, from time to time 1894 you may need to do this if you get unknown user in the following 1895 step. It never hurts to do it all the time. You may need to 1896 install a new mergemaster (cd src/usr.sbin/mergemaster && make 1897 install) after the buildworld before this step if you last updated 1898 from current before 20020224 or from -stable before 20020408. 1899 1900 [6] 4.x boot loader can be used to boot a 5.x system, however 1901 it is difficult to do that at best. If you wish to try, then 1902 you should interrupt the boot and at the ok prompt type: 1903 ok unload 1904 ok boot /boot/kernel/kernel 1905 If this fails to work, you must install a new boot loader as 1906 described here. 1907 1908 [7] Before you upgrade, please make sure that you are not using 1909 compatibility slices. These are device names of the form /dev/ad0a 1910 without the actual slice name. These will break with 5.x and newer. 1911 You generally must update these entries to use the post FreeBSD 1912 2.x form of /dev/ad0s1a. i386 and pc98 are affected, while alpha 1913 is not. 1914 1915 [8] In order to have a kernel that can run the 4.x binaries 1916 needed to do an installworld, you must include the COMPAT_FREEBSD4 1917 option in your kernel. Failure to do so may leave you with a system 1918 that is hard to boot to recover. 1919 1920 Make sure that you merge any new devices from GENERIC since the 1921 last time you updated your kernel config file. 1922 1923 [9] When checking out sources, you must include the -P flag to have 1924 cvs prune empty directories. 1925 1926 If CPUTYPE is defined in your /etc/make.conf, make sure to use the 1927 "?=" instead of the "=" assignment operator, so that buildworld can 1928 override the CPUTYPE if it needs to. 1929 1930 MAKEOBJDIRPREFIX must be defined in an environment variable, and 1931 not on the command line, or in /etc/make.conf. buildworld will 1932 warn if it is improperly defined. 1933 1934 In case you would like to avoid installing new packages of everything, 1935 you might want to uncomment the "COMPAT4X= YES" entry, so that 4.x 1936 compatibility libraries are built which should allow you to continue 1937 using your existing software for a while. Alternatively, you can 1938 install the misc/compat4x port. 1939 1940 [10] In order to create temporary files, /dev/random must be 1941 initialized by feeding data into it. src/etc/rc.d/preseedrandom 1942 takes care of this. 1943FORMAT: 1944 1945This file contains a list, in reverse chronological order, of major 1946breakages in tracking -current. Not all things will be listed here, 1947and it only starts on March 15, 2000. Updating files can found in 1948previous releases if your system is older than this. 1949 1950Copyright information: 1951 1952Copyright 1998-2004 M. Warner Losh.
