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 2620040914: 27 The format of the pflogd(8) logfile "/var/log/pflog" has changed for 28 architectures that have a 64 bit long type to make it compatible to 29 the standard pcap format. In order to prevent corruption move away 30 any old logfile before using a new pflogd(8). 31 3220040906: 33 debug.witness_* has been renamed to debug.witness.*. There are 34 compatibility tunables left in for a few days. Update loader.conf 35 as necessary. 36 3720040902: 38 The ifi_epoch change has been reverted because the ABI breakage 39 was too extensive. If you are running with a kernel/userland 40 containing the initial change (20040830), you should heed the 41 warning about ifconfig incompatibility when upgrading again. 42 With this change, 5.3 and 6.0 ifconfigs and kernels are once 43 again interoperable. 44 4520040830: 46 A new variable, ifi_epoch, has been added to struct if_data 47 which is part if struct ifnet. This means all network drivers 48 and network monitoring applications need to be recompiled. 49 50 WARNING WARNING WARNING WARNING WARNING WARNING WARNING 51 52 This also breaks ifconfig compatibility. An old ifconfig will 53 not work with the new kernel and a new ifconfig will not work 54 with the old. It is strongly recommended that you make a copy 55 of your old ifconfig before installworld. If you are installing 56 remotely, you must copy over a new ifconfig before rebooting in 57 to the new kernel. 58 5920040828: 60 The default configuration for the network stack has been changed 61 such that it now runs without the Giant lock unless configured 62 otherwise. If you experience network-related instability, you 63 may wish to try setting "debug.mpsafenet=0" or compiling the 64 kernel with "options NET_WITH_GIANT". Details on the netperf 65 project may be found at: 66 67 http://www.watson.org/~robert/freebsd/netperf/ 68 69 Including the 20040828 announcement of configuration change 70 details. 71 7220040827: 73 PFIL_HOOKS are a fixed part of the network stack now and do not 74 need to be specified in the kernel configuration file anymore. 75 7620040819: 77 Netgraph changed its message format slightly to align the data 78 portion well on 64 bit machines. 79 Netgraph using utilities (e.g. ngctl, nghook, ppp, mpd, 80 pppoed, bluetooth, ATM) should be recompiled when a new kernel 81 is installed. 82 8320040817: 84 IPFW has been converted to use PFIL_HOOKS. This change is 85 transparent to userland and preserves the ipfw ABI. The ipfw 86 core packet inspection and filtering functions have not been 87 changed, only how ipfw is invoked is different. Note that 88 "option PFIL_HOOKS" is required to use IPFIREWALL compiled 89 into the kernel or as KLD. 90 9120040814: 92 The RANDOM_IP_ID option has been replaced by the sysctl 93 net.inet.ip.random_id. If you had RANDOM_IP_ID in your kernel then 94 you may want to add "net.inet.ip.random_id=1" to /etc/sysctl.conf. 95 9620040807: 97 The size of 'struct ifnet' has changed due to the addition of the 98 if_carp placeholder. All kernel modules implementing network 99 interfaces must be recompiled as a result. 100 10120040806: 102 Module loading has been fixed. Some older installations will 103 drop proper module_path initialization and modules will fail to 104 load properly. If you have a line in /boot/loader.rc that says: 105 "initialize drop", do (i386 only): 106 cp /usr/src/sys/boot/i386/loader/loader.rc /boot/loader.rc 107 chown root:wheel /boot/loader.rc 108 chmod 444 /boot/loader.rc 109 11020040802: 111 making /dev/(null|zero) into a module proved to be too unpopular, 112 so this bit has been revoked from the previous (20040801) entry. 113 11420040801: 115 The /dev/mem, /dev/io /dev/(null/zero) devices are now modules, 116 so you may wish to add them to your kernel config file. See 117 GENERIC for examples. 118 11920040728: 120 System compiler has been upgraded to GCC 3.4.2-pre. As with any major 121 compiler upgrade, there are several issues to be aware of. GCC 3.4.x 122 has broken C++ ABI compatibility with previous releases yet again 123 and users will have to rebuild all their C++ programs with the new 124 compiler. If you are getting run-time error such as 125 /libexec/ld-elf.so.1: Undefined symbol "_ZNSs20_S_empty_rep_storageE" 126 This entry does apply to you. 127 128 A new unit-at-a-time optimization mode, which is default in this 129 compiler release, is more aggressive in removing unused static 130 symbols. This is the likely cause of 'make buildworld' breakages 131 with non-default CFLAGS where optimization level is set to -O2 132 or higher. 133 134 With the upgrade of the system compiler, the kernel has been upgraded 135 to match the new system compiler. This makes it impossible to build 136 a new kernel with the old compiler. Upgrade your system via 137 make buildworld and make kernel (see below) to fix this problem. 138 13920040727: 140 The size of 'struct ifnet' has changed due to the addition of 141 the IFF_NEEDSGIANT flag (and what it implies). All kernel 142 modules implementing network interfaces must be recompiled as 143 a result. 144 14520040716: 146 The sound device drivers are renamed. `sound' is always required, 147 while `snd_*' should be configured accordingly to your hardware. 148 Refer to NOTES for the detail of the drivers. 149 15020040710: 151 __FreeBSD_version bumped to 502122. 152 15320040710: 154 The console initialization on Alpha has been reworked and is now 155 identical to other platforms. This means that the hardcoding of 156 the serial console and the debug port has been removed. As such, 157 hints are now required for the sio(4) driver to become a console 158 or debug port. The NO_SIO option has been decommissioned because 159 of this. 160 16120040710: 162 A revamp of the debugging code in the kernel with some visible 163 changes beyond just the debugging experience: 164 o The DDB option is now specific to the DDB debugger backend 165 and should not be used any more for conditional compilation 166 of debugging code for when debugging is enabled. Use the KDB 167 option for this. 168 o The WITNESS_DDB, DDB_TRACE and DDB_UNATTENDED options have 169 been renamed to WITNESS_KDB, KDB_TRACE and KDB_UNATTENDED 170 respectively. This is in line with the first bullet. 171 o The remote GDB support has been untangled from DDB and needs 172 to be enabled separately now. Use the GDB option for this. 173 o The GDB_REMOTE_CHAT option has been removed. Support for this 174 homegrown feature is discontinued. The GDB remote protocol 175 supports console output and it makes sense to use that. 176 o The DDB_NOKLDSYM option has been removed. The DDB debugger 177 now supports both direct symbol table lookups as well as KLD 178 symbol lookups through the linker. 179 18020040708: 181 Bluetooth code has been marked as non-i386 specific. 182 __FreeBSD_version has been bumped to 502121 to mark this change. 183 18420040702: 185 The native preemption has been added to the kernel scheduler. 186 There is some report that the ULE scheduler was broken in some 187 machines and we encourage users using the ULE scheduler either 188 stick with a known good kernel, or temporarily switch to the 4BSD 189 scheduler as a workaround. 190 19120040630: 192 The netgraph ABI version number has been incremented to indicate 193 an incompatible change in the ABI. Old netgraph nodes will refuse 194 to attach until recompiled. Netgraph now uses mbuf tags to move 195 metadata and this commit removes its home-grown metadata facility. 196 Nodes should just recompile, unless they use metadata, in which 197 case the changes are simple; the file ng_ksocket.c serves as an 198 example of such changes. 199 200 This also broke i4b, although the compile problem has been papered 201 over. 202 20320040630: 204 ACPI has been updated to disable known-bad BIOS revisions. A message 205 will be printed on the console indicating that ACPI has been disabled 206 automatically and that the user should use a newer BIOS, if possible. 207 If you think ACPI does work on your system and want to override 208 this (i.e., for testing), set hint.acpi.0.disabled="0" at the 209 loader prompt. 210 21120040623: 212 pf was updated to OpenBSD-stable 3.5 and pflogd(8) is privilege 213 separated now. It uses the newly created "_pflogd" user/group 214 combination. If you plan to use pflogd(8) make sure to run 215 mergemaster -p or install the "_pflogd" user and group manually. 216 21720040622: 218 Network interface cloning has been overhauled. This change will 219 require a recompile of modules using cloning and modification of 220 external ones to the new API. __FreeBSD_version has been bumped 221 to 502119 to mark this change. Additionally, users creating 222 stf(4) interfaces via "ifconfig stf" will need to update their 223 scripts as this will create an interface named "stf" instead of 224 "stf0" and ifconfig will not print "stf0" to stdout. 225 22620040621: 227 On 20040524, the /etc/rc.d/nsswitch script was modified to 228 automatically create /etc/nsswitch.conf on startup if it did 229 not already exist. Unfortunately, an error in the man page 230 was carried over to the script, resulting in incorrect 231 nsswitch settings. The simplest remedy is to remove both 232 /etc/nsswitch.conf and /etc/host.conf; they will be recreated 233 during the next reboot. 234 23520040614: 236 The return value of sema_timedwait(9) has been changed to 237 make it consistent with cv_timedwait(9). Be sure to recompile 238 the ips module and any third-party modules which call 239 sema_timedwait. 240 24120040613: 242 ALTQ is now linked to the build. This breaks ABI for struct ifnet. 243 Make sure to recompile modules and any userland that makes use of 244 sizeof(struct ifnet). In order to get the altq headers in place 245 please recompile and reinstall world. 246 24720040607: 248 Splitting kern_thread.c into 2 files (adding kern_kse.c) 249 requires that you re-run config after updating your tree. 250 25120040601: 252 The MIDI drivers have been removed. Until the new module-friendly 253 ones are merged, remove or comment out midi and seq from your 254 kernel configuration. 255 25620040423: 257 Due to a new option in ipfw (versrcreach) the ipfw(8) command 258 needs to be recompiled. Normal accept/reject rules without 259 options are not affected but those with options may break until 260 ipfw(8) is recompiled. 261 26220040420: 263 Due to changes in the callout ABI, kernels compiled after this 264 date may be incompatible with kernel modules compiled prior to 265 20040406. 266 26720040414: 268 The PCI bus power state stuff has been turned on. If this causes 269 problems for your system, please disable it using the tunable 270 hw.pci.do_powerstate=0. 271 27220040412: 273 The bulk of the pci problems have been fixed, although the floppy 274 drive is still broken. 275 27620040410: 277 A substantial update to the pci bus resource and power management 278 have been committed. Expect a bumpy ride for a few days until 279 the unanticipated problems have been resolved. 280 28120040409: 282 Due to changes in the the Yarrow initialization process, 283 /dev/random needs to be fed before operations requiring 284 temp files can succeed in single user mode. This includes 285 running "make installworld". /dev/random may be fed by running 286 "/etc/rc.d/initrandom start" or with 20040415 source by running 287 "/etc/rc.d/preseedrandom". 288 28920040322: 290 The debug.mpsafenet tunable controls whether the kernel Giant 291 lock is held across the lower levels of the network stack, and 292 by default is turned off. In the few days following 20040322, 293 the behavior of debug.mpsafenet will change such that this 294 tunable controls Giant over all levels of the network stack. 295 If you are currently setting debug.mpsafenet to 1, you should 296 set it back to 0 (the default) again during the change-over. 297 An additional note will be added to UPDATING when sufficient 298 locking is merged to permit this to take place. 299 30020040310: 301 The FreeBSD/sparc64 platform is changing time_t from 32-bits to 302 64-bits. This is a very major incompatible change, so people 303 using FreeBSD/sparc64 *must* read the UPDATING.64BTT file for 304 detailed instructions on how to make this upgrade. People 305 upgrading FreeBSD on other platforms can ignore this event. 306 30720040308: 308 The packet filter (pf) is now installed with the base system. Make 309 sure to run mergemaster -p before installworld to create required 310 user account ("proxy"). If you do not want to build pf with your 311 system you can use the NO_PF knob in make.conf. 312 Also note that pf requires "options PFIL_HOOKS" in the kernel. The 313 pf system consists of the following three devices: 314 device pf # required 315 device pflog # optional 316 device pfsync # optional 317 31820040303: 319 If you are having trouble with the libc_r -> libpthread transition 320 (see the 20040130 entry), place the following lines at the top of 321 /etc/libmap.conf: 322 323 libc_r.so.5 libpthread.so.1 324 libc_r.so libpthread.so 325 326 This will cause all programs and libraries linked against libc_r 327 to use libpthread instead. 328 32920040226: 330 Some sshd configuration defaults have changed: protocol version 1 331 is no longer enabled by default, and password authentication is 332 disabled by default if PAM is enabled (which it is by default). 333 OpenSSH clients should not be affected by this; other clients may 334 have to be reconfigured, upgraded or replaced. 335 33620040225: 337 The ABIs defined in <resolv.h> and <netdb.h> have been updated 338 to support improved reentrancy. Multi-threaded programs that 339 reference the "_res" or "h_errno" symbols may experience some 340 problems if they are not recompiled. Single-threaded programs 341 should remain unaffected. 342 34320040225: 344 routed has been updated in the base system from the vendor 345 sources, routed v2.27, from rhyolite.com. This change means that 346 for users who use RIP's MD5 authentication feature, FreeBSD 347 -CURRENT's routed is now incompatible with previous versions 348 of FreeBSD; however it is now compatible with implementations 349 from Sun, Cisco and other vendors. 350 35120040224: 352 The tcpcb structure has changed and makes a recompile of libkvm 353 and related userland network utilities necessary. 354 35520040222: 356 The cdevsw structure has changed in two externally visible ways. 357 First, the sense of the D_GIANT flag has changed to D_NEEDSGIANT. 358 Second, the d_version field must be filled in with D_VERSION. 359 Drivers outside the tree will need to be updated. 360 36120040207: 362 The /etc/rc.d/ttys script has been removed. It is no longer 363 necessary since devfs has been mandatory for some time. 364 36520040130: 366 libkse has been renamed back to libpthread and is now the 367 default threads library. The gcc -pthread option has also 368 been changed to link to libpthread instead of libc_r. For 369 alpha and sparc64 machines, libkse is not renamed and links 370 are installed so that libpthread points to libc_r. Until 371 the ports system is updated to handle this change, it is 372 recommended that folks install an /etc/libmap.conf(5) that 373 maps libc_r to libpthread. If you have any binaries or 374 libraries linked to libkse, then it is also recommended 375 that you map libkse to libpthread. Anyone that is using 376 nvidia supplied drivers and libraries should use a libmap.conf 377 that maps libpthread to libc_r since their drivers/libraries 378 do not work with libpthread. 379 38020040125: 381 ULE has entered into its probationary period as the default scheduler 382 in GENERIC. For the average user, interactivity is reported to be 383 better in many cases. On SMP machines ULE will be able to make more 384 efficient use of the available parallel resources. If you are not 385 running it now, please switch over, replacing the kernel option 386 SCHED_4BSD with SCHED_ULE. 387 38820040125: 389 Move LongRun support out of identcpu.c, where it hardly 390 belongs, into its own file and make it opt-in, not mandatory, 391 depending on CPU_ENABLE_LONGRUN config(8) option. 392 39320031213: 394 src/lib/libc/gen/initgroups.c:1.8 now causes logins to fail 395 if the login process is unable to successfully set the 396 process credentials to include all groups defined for the 397 user. The current kernel limit is 16 groups; administrators 398 may wish to check that users do not have over 16 groups 399 defined, or they will be unable to log in. 400 40120031203: 402 The ACPI module has been reactivated. It is no longer required 403 to compile ACPI support into kernels statically. 404 40520031112: 406 The statfs structure has been updated with 64-bit fields to 407 allow accurate reporting of multi-terabyte filesystem 408 sizes. You should build world, then build and boot the new kernel 409 BEFORE doing a `installworld' as the new kernel will know about 410 binaries using the old statfs structure, but an old kernel will 411 not know about the new system calls that support the new statfs 412 structure. 413 Note that the backwards compatibility is only present when the 414 kernel is configured with the COMPAT_FREEBSD4 option. Since 415 even /bin/sh will not run with a new kernel without said option 416 you're pretty much dead in the water without it. Make sure you 417 have COMPAT_FREEBSD4! 418 Running an old kernel after a `make world' will cause programs 419 such as `df' that do a statfs system call to fail with a bad 420 system call. Marco Wertejuk <wertejuk@mwcis.com> also reports 421 that cfsd (ports/security/cfs) needs to be recompiled after 422 these changes are installed. 423 424 ****************************DANGER******************************* 425 426 DO NOT make installworld after the buildworld w/o building and 427 installing a new kernel FIRST. You will be unable to build a 428 new kernel otherwise on a system with new binaries and an old 429 kernel. 430 43120031112: 432 Some netgraph string length constants have been changed. This 433 change requires the netgraph kernel modules and all netgraph 434 userland components to be in sync. Especially users who require 435 netgraph to boot need to make sure to have world and kernel in 436 sync before rebooting. 437 43820031111: 439 Hyperthreading logical CPU's are no longer probed by default 440 when using the MP Table. If ACPI is being used, then logical 441 CPUs will be probed if hyperthreading is enabled in the BIOS. 442 If ACPI is not being used and hyperthreading is enabled in the 443 BIOS, logical CPUs can be enabled by building a custom kernel 444 with the option MPTABLE_FORCE_HTT enabled. 445 44620031103: 447 The i386 APIC_IO kernel option has been replaced by 448 'device apic'. The ACPI module has also been temporarily 449 disabled, so ACPI must be statically compiled into your 450 kernel using 'device acpi' if you wish to use the ACPI driver. 451 45220031031: 453 The API and ABI of struct ifnet have been changed by removing 454 the if_name and if_unit members and replacing them with 455 if_xname, if_dname, and if_dunit. All network drivers and most 456 userland programs which include net/if_var.h must be updated 457 and recompiled. __FreeBSD_version has been bumped to 501113 to 458 reflect this change. 459 46020030928: 461 Changes to the cdevsw default functions have been made to remove 462 the need to specify nullopen() and nullclose() explicitly. 463 __FreeBSD_version bumped to 501110. 464 46520030926: 466 kiconv(3) has been added. mount_msdosfs(8), mount_ntfs(8) and 467 mount_cd9660(8) need to be in sync with kernel. 468 46920030925: 470 Configuring a system to use IPFILTER now requires that PFIL_HOOKS 471 also be explicitly configured. Previously this dependency was 472 magically handled through some cruft in net/pfil.h; but that has 473 been removed. Building a kernel with IPFILTER but not PFIL_HOOKS 474 will fail with obtuse errors in ip_fil.c. 475 47620030923: 477 Fix a bug in arplookup(), whereby a hostile party on a locally 478 attached network could exhaust kernel memory, and cause a system 479 panic, by sending a flood of spoofed ARP requests. See 480 FreeBSD-SA-03:14.arp. 481 48220030915: 483 A change to /etc/defaults/rc.conf now causes inetd to be started 484 with `-C 60' if it is not overridden in /etc/rc.conf. This 485 causes inetd to stop accepting connections from an IP address 486 that exceeds the rate of 60 connections per minute. 487 48820030829: 489 The following rc.d scripts have been removed and should be 490 deleted from your installation: atm2.sh atm3.sh devdb 491 localdaemons network1 network2 network3. Depending on when 492 you last updated world and used mergemaster(8) you may or 493 may not have problems during the rc boot sequence. The simplest 494 solution is an 'rm -rf /etc/rc.d/*' and then 'mergemaster -i'. 495 The atm2.sh atm3.sh and devdb scripts were removed some time 496 ago, so depending on when you installed -CURRENT these scripts 497 may or may not exist on your system. 498 49920030824: 500 ATAng has been committed. You need to build world as sys/ata.h 501 has changed, and userland atacontrol depends on it. 502 If you use ATA SW raids you need "device ataraid" in your 503 kernel config file, as it is no longer pulled in automatically. 504 50520030819: 506 The OFW_NEWPCI option has been turned on in the Sparc64 GENERIC kernel. 507 Among other things, this changes the device enumeration to be 508 closer to Solaris. Be aware that, this can even cause the machine 509 to not boot without manual intervention before the fstab is adjusted. 510 51120030728: 512 All current USB and Firewire quirks in da(4) have been deprecated 513 and will be removed for 5.2. If this causes failure for your 514 umass(4) devices, enable "options DA_OLD_QUIRKS" in your kernel 515 and send the output of "camcontrol inquiry da0" to scsi@freebsd.org 516 so the quirk can be re-enabled. 517 51820030724: 519 Problems with entry 20030714 have been corrected and no known issues 520 with /rescue and -j exist for host systems after this point in time. 521 52220030722: 523 FPU-less support has been removed from FreeBSD. Chances are you won't 524 notice. 386+387 support should still work after this change, but 525 it is now a minimum requirement for the i386 port that you have real 526 FPU hardware. 527 52820030714: 529 Some people are having problems with changes related to /rescue. 530 If you are building -j N, you will need to define NO_RESCUE. Others 531 will need to define it if /rescue has issues with their environment. 532 People should report those issues to current@. 533 53420030711: 535 gcc was upgraded to 3.3. You are advised to not build -DNOCLEAN 536 across this point. Further, it might be a good idea to remove 537 /usr/obj. 538 53920030610: 540 Remove deprecated locale names and transition period code 541 for them, finishing switching to the new scheme. Check your 542 LANG environment variable. 543 54420030609: 545 CCD has been changed to be a fully GEOMified class. Kernel 546 and ccdconfig(8) needs to be in sync, this is particularly 547 important to remember beforehand if your source tree is on 548 a ccd device. Consider making a copy of the old ccdconfig 549 into /boot/kernel.good or wherever you keep your backup 550 kernel. 551 55220030605: 553 There was a small window in which sed(1) was broken. If you 554 happen to have sed(1) installed during that window, which is 555 evidenced by an inability to build world with the failure 556 given below, you need to manually build and install sed(1) 557 (and only sed(1)) before doing anything else. This is a one- 558 time snafu. Typical failure mode: 559 560 In file included from /usr/src/contrib/binutils/bfd/targets.c:1092: 561 targmatch.h:7:1: null character(s) ignored 562 targmatch.h:12:1: null character(s) ignored 563 targmatch.h:16:1: null character(s) ignored 564 : 565 566 The window of "sed(1)-uction" is from Wed Jun 4 15:31:55 2003 UTC 567 to Thu Jun 5 12:10:19 2003 UTC (from rev 1.30 to rev 1.31 of 568 usr.bin/sed/process.c). 569 57020030505: 571 Kerberos 5 (Heimdal) is now built by default. Setting 572 MAKE_KERBEROS5 no longer has any effect. If you do NOT 573 want the "base" Kerberos 5, you need to set NO_KERBEROS. 574 57520030502: 576 groff has been updated. If you try to do a buildworld and 577 get an infinite loop in troff, update to May 4th or newer. If you 578 have a newer kernel than userland, you may need to set the OSRELDATE 579 to 500110 in your environment before starting a buildworld. 580 58120030501: 582 The old rc system has been removed. Please report any problems 583 to freebsd-rc@yahoogroups.com, and/or freebsd-current@freebsd.org. 584 Your personal versions of these files will not be removed, so you can 585 continue to use them. However, you should take great care when updating, 586 especially when using mergemaster, since the compatibility code that 587 utilizes these old scripts has also been removed. 588 58920030423: 590 A bug has been fixed in /dev/devctl which would cause devd 591 to hang on boot, were it not for a workaround in devd. The 592 work around in devd will be removed around 20030507. You 593 have until then to upgrade your kernel before updating 594 userland. In general, you should have a userland and 595 kernel that's in sync with each other. However, given the 596 effects of this bug (hang on boot when starting devd), some 597 allowances are made. 598 59920030329: 600 Alphas with libc from between 20030312 and 20030329 exhibit 601 floating point exceptions (FPEs), most notably in awk(1) 602 while upgrading the system through a buildworld. 603 604 So, to successfully upgrade your Alpha, you must either 605 downgrade your libc.so to a pre-20030312 version, or update 606 /usr/share/mk/bsd.cpu.mk to revision 1.26 which adds -mieee 607 to CFLAGS, then forcibly rebuild and install libc: 608 609 cd /usr/src/lib/libc && \ 610 make cleandir && make obj && \ 611 make -DNOMAN -DNOPROFILE all && \ 612 make -DNOMAN -DNOPROFILE install 613 61420030208: 615 sendmail 8.12.7 has been imported. It has one important 616 change for IPv6 users. The default submit.mc now uses 617 '[127.0.0.1]' instead of 'localhost' meaning only IPv4 is 618 used to connect to the MTA. Users on IPv6-only machines 619 will need to edit /etc/mail/submit.mc appropriately. 620 62120030128: 622 NODEVFS option has been removed and DEVFS thereby made standard. 623 This makes all references to MAKEDEV obsolete, and they should 624 be removed when convenient. 625 62620030126: 627 The name of the device for the ofw console has changed, sparc64 users 628 must run mergemaster to update their installed /etc/ttys. 629 63020030125: 631 The scheduler framework has grown a second scheduler and consequently 632 you must specify one and only one scheduler in your kernel config. 633 The cvs config files have been updated to use the old scheduler 634 which may be selected via 'options SCHED_4BSD'. If you would like 635 to try the new, much more experimental, scheduler please try 636 'options SCHED_ULE' and contribute to the arch@ discussion. 637 63820030115: 639 A new version of the wi driver has been imported into the tree. 640 One now must have device wlan in the config file for it to operate 641 properly. 642 643 In addition, there have been some changes to how wi devices are 644 configured for point to point links to bring it more in line 645 with the former way of doing things, as well as compatibility 646 with NetBSD. 647 64820021222: 649 For a period after the GCC 3.2.1 import (from 12/04 to 12/22), GCC 650 used an incompatible form of ABI for returning structures and unions 651 which FreeBSD's GCC maintainers were not aware of relative to previous 652 versions of FreeBSD. We have gone back to the ABI for now, and any 653 code compiled which is required to interoperate with other code (not 654 built at the same time) returning structs or unions should be 655 rebuilt. 656 65720021216: 658 A name change in /etc/netconfig has been reverted to stay 659 compatible with suns TIRPC and also with NetBSD. You need 660 to run mergemaster after make world. A new libc does still work 661 with an outdated /etc/netconfig for some time, but you'll get 662 a warning. This warning will be removed in 20030301. 663 66420021202: 665 The recent binutils upgrade marks a kernel flag day on 666 sparc64: modules built with the old binutils will not work 667 with new kernels and vice versa. Mismatches will result in 668 panics. Make sure your kernel and modules are in sync. 669 67020021029: 671 The value of IPPROTO_DIVERT has changed. Make sure to keep 672 your kernel, netstat, natd and any third-party DIVERT 673 consumers in sync. 674 67520021024: 676 Old, compatibility slices have been removed in GEOM kernels. 677 This means that you will have to update your /etc/fstab to 678 not use disk devices of the form /dev/ad0a. Instead, you 679 now must specify /dev/ad0s1a, or whatever slice your FreeBSD 680 partition really is on. The old device names have gone 681 away, so if you use them anywhere else, you must also adjust 682 those uses. (This doesn't affect the disks formatted in 683 the ``dangerously-dedicated'' mode.) 684 68520021023: 686 Alphas with kernels from between 20020830 and 20021023 and/or 687 rtld (ld-elf.so.1) older than 20021023 may experience problems 688 with groff while doing a buildworld (kernel: "out of memory", 689 fixed in rev 1.129 of kern/imgact_elf.c; rtld: "too few PT_LOAD 690 segments", fixed in rev 1.8 of libexec/rtld-elf/map_object.c). 691 692 So, to successfully upgrade your Alpha, you must either 693 upgrade your kernel and rtld first (which might be a bit 694 tricky), or avoid running the bootstrapped groff during the 695 "transitional" buildworld. To avoid running groff during the 696 transitional upgrade run make buildworld with -DNOMAN, 697 -DNO_SHAREDOCS, and -DNO_LPR. 698 69920020831: 700 gcc has been upgraded to 3.2. It is not all binary compatible 701 with earlier versions of gcc for c++ programs. All c++ 702 programs and libraries need to be recompiled. 703 704 Also, if you encounter g++ issues, rm /usr/include/g++/* before 705 doing an installworld to make sure that stale files are removed. 706 70720020827: 708 Our /etc/termcap now has all the entries from the XFree86 xterm 709 almost unchanged. This means xterm now supports color by default. 710 If you used TERM=xterm-color in the past you now should use 711 TERM=xterm. (xterm-color will lead to benign warnings). 712 71320020815: 714 A "bug" in gcc(1) that was hiding warning in system headers was 715 fixed. It's probably time to add -DNO_WERROR to your make line 716 again. 717 71820020729: 719 COPY is being deprecated. The 20010530 change was reverted, as 720 it causes far more pain than was expected, and to always compare 721 before installing, please use INSTALL="install -C" again. The 722 -C option is now silently ignored when used with the -d option. 723 72420020702: 725 Problems with libc_r clients like KDE and GNOME have been resolved. 726 There are still some minor problems with some signals but the 727 system is stable enough for general use again. SMP is less so than UP 728 but each can successfully complete multiple buildworlds. 729 Libkvm needs to be recompiled due to KSE. 730 73120020701: 732 Now would be a bad time to upgrade. Something in or near the 733 KSE commit totally broke programs using libc_r like KDE and 734 GNOME. 735 73620020511: 737 The k5su utility installed as part of Kerberos 5 is no longer 738 installed with the set-user-ID bit set by default. Add 739 ENABLE_SUID_K5SU=yes to /etc/make.conf to have it installed 740 with the set-user-ID bit set. 741 74220020510: 743 Gcc 3.1 debugging format (cc -g) has changed from STABS to DWARF2. 744 Unfortunately our native GDB (at version 4.18) does not understand 745 the DWARF2 debugging format. Thus you must use `gcc -gstabs+' to 746 generated debugging information for our native GDB. 747 74820020510: 749 Due to the way CVS works, it may not properly update src/contrib/gcc 750 to the 3.1 sources. The easiest fix is to `rm -rf' src/contrib/gcc 751 and then do a cvs update. 752 75320020421: 754 When exec'ing set[ug]id executables, the kernel now ensures that the 755 stdio file descriptors (0..2) are open. See FreeBSD-SA-02:23.stdio. 756 75720020404: 758 New sendmail startup scripts have been installed to make it 759 easier to use alternative MTAs with FreeBSD. Setting the rc.conf 760 variable sendmail_enable to "NO" no longer prevents any sendmail 761 daemons from starting. Instead, either set sendmail_enable to 762 "NONE" or change mta_start_script to a script for starting 763 an alternative MTA. Setting mta_start_script to "" will 764 also prevent any MTA from being started at boot. 765 76620020403: 767 UCONSOLE is no longer a valid kernel option. 768 76920020315: 770 FreeBSD 5.0 DP-1 was basically branched today. 771 77220020225: 773 Warnings are now errors in the kernel. Unless you are a developer, 774 you should add -DNO_WERROR to your make line. 775 77620020217: 777 sendmail 8.12.2 has been imported. The sendmail binary is no 778 longer a set-user-ID root binary and the infrastructure to support 779 command line mail submission has changed. Be sure to run 780 mergemaster (especially for updating /etc/rc, /etc/defaults/rc.conf, 781 and /etc/mail) and read /etc/mail/README for more details. 782 783 Due to the import of sendmail 8.12.2, a new user and group are 784 required in order for sendmail to run as a set-group-ID 785 binary. A 'make installworld' will use the new user and group 786 to set the owner and group of /var/spool/clientmqueue and will 787 fail if the new user and group do not exist. The 'smmsp' user 788 and group must be merged from src/etc/group and 789 src/etc/master.passwd before using 'make installworld'. 790 'mergemaster -p' will do this. You may need to install 791 mergemaster before this will work if you are updating from a 792 very old version of current. The updating recipe has changed 793 as of this date. 794 79520020112: 796 The preferred configuration method for PAM is now /etc/pam.d/ 797 rather than /etc/pam.conf. If you have an unmodified 798 pam.conf, just delete it after your next mergemaster run. If 799 you have local modifications, you can use 800 /usr/src/etc/pam.d/convert.pl to incorporate them into your 801 /etc/pam.d. 802 803 Please see the following url for more details: 804http://www.freebsd.org/cgi/mid.cgi?db=mid&id=<xzp6667fyoa.fsf@flood.ping.uio.no> 80520011229: 806 If anyone here is already using the new rc.conf(5) variable 807 networkfs_types, please note that it has changed 808http://www.freebsd.org/cgi/mid.cgi?db=mid&id=<9744.1009655556@axl.seasidesoftware.co.za> 809 81020011220: 811 sys/i4b/driver/i4b_ispppsubr.c has been retired. This file 812 started out its life in the ISDN4BSD project as an offspring 813 from sys/net/if_spppsubr.c, which eventually got a life of its 814 own. All the accumulated features and bug fixes of the i4b 815 version have now been merged back into the base system's 816 version now. The only user-visible change resulting from this 817 is that i4b's sppp(4) interfaces are to be managed with 818 spppcontrol(8) again, since ispppcontrol(8) has been retired 819 as well. (There has never been rc file support for 820 ispppcontrol in -current, but only in -stable. That will be 821 reverted by the time the changes are MFCed.) 822 82320011215: 824 The fdc(4) driver has been updated and now automatically 825 recognizes media in `standard' formats (like 1440 KB and 826 720 KB for a 3.5" high-density drive) when accessing the 827 default device node (e. g. /dev/fd0). The old variety of 828 floppy device nodes /dev/fd*.* is no longer present by 829 default, devices can be created (in DEVFS) on demand. They 830 will need to be customized then for `odd' densities using 831 fdcontrol(8). 832 83320011209: 834 The bugs in procfs' debugging support code have been fixed, 835 and truss(1) now works again. 836 83720011207: 838 Daily security checks have been split out to use the periodic(8) 839 scripts. Some change in configuration may be necessary. Please 840 see 841http://www.freebsd.org/cgi/mid.cgi?db=mid&id=<20011207155805.R8975@blossom.cjclark.org> 842 for details. 843 84420011204: 845 sos added VCD/SVCD support to ata driver and that needs the 846 kernel and burncd to be in sync. 847 84820011203: 849 The procfs pseudo-filesystem has now been converted to use the 850 pseudofs framework. If you have 'options PROCFS' in your 851 kernel config, you'll need to add 'options PSEUDOFS' if it's 852 not there already. 853 854 This change temporarily breaks truss(1); use ktrace(1) instead 855 until the issue has been resolved. 856 85720011202: 858 A security hole in OpenSSH involving `UseLogin yes' has been 859 patched. 860 86120011126: 862 You need to remove /usr/obj/.../usr.bin/tip before rebuilding 863 after this date. You need to do this only once. 864 86520011103: 866 Most of the awk issues have been resolved. Some rough 867 edges may be left, but for the most part things should be 868 back to "normal." For CURRENT's usual definition of "normal." 869 87020011030: 871 Awk has been upgraded to the one true awk from bell labs. Expect 872 choppy waves in the upgrade process. 873 87420011030: 875 The asr driver problem has been resolved. 876 87720011027: 878 Due to changes in other parts of the system, the asr driver 879 now causes the system to panic on boot. Do not use it pending 880 correction. Comment it out of any kernel config file that you 881 try to use from this date forward. 882 88320011025: 884 When crossbuilding, use TARGET=xxx where you used to use 885 MACHINE=xxx. You don't need to set TARGET_ARCH and TARGET, 886 unless you are changing both of them. To cross build pc98 on 887 an alpha, for example, you need to set TARGET=pc98 and 888 TARGET_ARCH=i386. 889 89020011001: 891 The kernel interface that burncd depends on has changed. 892 You must recompile both the kernel and userland applications 893 at the same time. 894 89520010929: 896 When crossbuilding, please set TARGET_ARCH rather than 897 MACHINE_ARCH to indicate the target. In the future, one will 898 set TARGET_MACHINE where you set MACHINE now. At the moment, 899 setting MACHINE alone for same MACHINE_ARCH machines works 900 (eg, you can build pc98 on an i386 machine and vice versa). 901 90220010927: 903 Some weird problems result from using ACPI on some machines. 904 To disable ACPI you can add 905 hint.acpi.0.disabled="1" 906 to /boot/loader.conf (or by putting set X=Y at the boot 907 loader "ok" prompt). 908 909 Alternatively, you can remove it from /boot/kernel/acpi.ko 910 or use the MODULES_OVERRIDE function in your kernel config 911 file and not list acpi in that list. 912 91320010924: 914 The buildworld has been fixed. You may need to install 915 the 4.x compatibility libraries for some old binaries 916 to work. Add COMPAT4X=true to your /etc/make.conf to 917 get them installed on every installworld, or execute the 918 following to get them installed only once: 919 cd src/lib/compat/compat4x.<arch> 920 make all install 921 You will see ``__stdoutp undefined'' until you do this. 922 92320010919: 924 There's a bug in the world build process. The cross-tools 925 are build with the NEW headers, but the OLD libc.a. This 926 leads to all kinds of problems with the new libc. A temporary 927 workaround is to add 928 CFLAGS="-O -pipe -D_OLD_STDIO" 929 before building world when upgrading from 4.x to current. This 930 can be removed afterwards. 931 932 A proper fix to the buildworld target is needed. 933 93420010918: 935 Peter has committed his new kthread nfs client/server code. 936 NFS may be unstable after this date. 937 93820010912: 939 KSE has hit the tree. Lots of things are now different in 940 the kernel. While a few problems were introduced in the 941 initial commit, most of the major ones have been found and 942 corrected. 943 94420010901: 945 In OLDCARD, CardBus bridges appear to be stable. The work 946 arounds described in the 20010604 entry are now no longer 947 necessary and will be ignored. Most insert/remove problems 948 have been rectified around this date. 949 95020010823: 951 named now runs as user bind and group bind rather than as 952 root. If named_enable is set to YES in /etc/rc.conf, ensure 953 that user bind is available in /etc/passwd (using vipw(8)) 954 and that group bind is available in /etc/group. Also make 955 sure that user or group bind has read (and not write) 956 permission for your name server configuration and that it 957 has read and write permission for your slave zone files and 958 directory. 959 960 If you wish to continue to run named as root (a less secure 961 alternative), add a line to /etc/rc.conf saying 962 963 named_flags= 964 96520010709: 966 The PAM libraries have had an API upgrade that is beyond 967 the ability of the shared library major number to handle. 968 It is manifested by PAM-using ports dumping core. The 969 solution is to rebuild those ports. 970 97120010628: 972 The kernel compile module has moved from src/sys/compile/FOO 973 to src/sys/${MACHINE}/compile/FOO. 974 97520010625: 976 The pccard modem issue from 20010613 has been corrected. 977 OLDCARD support is still a little weak in -current. slot 1 is 978 known not to work on some TI based cardbus bridges. Some 979 cardbus bridges do not properly detect insert/removal events. 980 IRQ configuration needs more safety belts. 981 98220010617: 983 Softupdates problems have been corrected. 984 98520010614: 986 Peter ripped out the linkerset support. You must, as always, 987 rerun config after you cvsup if you are using the traditional 988 kernel building methods. 989 99020010613: 991 pccard modems may not work with current after 20010604 date. Some 992 do, others result in panics. *MAKE*SURE* that you update your 993 config and /etc/rc.conf ala the 20010604 entry, or you will have 994 problems (this issue will be fixed, it just hasn't been yet). 995 99620010613: 997 SOFTUPDATES seem to be broken since the middle of May or so. Do not 998 use them in current. You can disable softupdates on all mounted 999 partitions, or remove SOFTUPDATES the kernel config file. 1000 100120010612: 1002 After Peter's commits to the hints code, people have been noticing 1003 that certain devices are attached (or try to) twice. This is due 1004 to having both static hints as well as a /boot/device.hints. To 1005 work around this issue, please use only one or the other mechanism 1006 until this bug is fixed. 1007 1008 Please note that a feature of config is that if you have config 1009 file FOO and FOO.hints, it automatically adds FOO.hints to the 1010 hints.c file, whether you want it to or not. 1011 101220010610: 1013 Locale names have changed to match other systems better. 1014 101520010604: 1016 pccard support for pci cards has been committed. You must change 1017 your /etc/pccard.conf irq lines. It must match the irq used by 1018 pcic device. Interrupt storms may result if you fail to do this. 1019 Interrupt storms look a lot like a hang. 1020 1021 You must also install a new pccardd, otherwise you will get an 1022 interrupt storm at card reset time (just after it tells you what 1023 it is). 1024 1025 pccardd_flags="-I" is necessary for the time being. It tells pccardd 1026 not to ask the kernel if the interrupt is really free or not before 1027 using it. You can either change the /etc/pccard.conf irq lines to 1028 match pcic, or add "-i X" to the pccardd_flags. 1029 103020010530: 1031 INSTALL=install -C is being deprecated. If you want to do this, 1032 use COPY=-C instead. The former method will be supported for only 1033 a limited time. If you see 1034 1035install: warning: the -d and -C options may not be specified together 1036 1037 in your makeworld, then you need to migrate towards using 1038 COPY=-C. 1039 104020010525: 1041 It appears that vm is now stable enough to use again. However, 1042 there may be other problems, so caution is still urged. alpha 1043 definitely is in bad shape. 1044 104520010521: 1046 Minor repo damage has happened. This may cause problems 1047 with cvsup of ports. If you get errors, please see 1048 http://www.FreeBSD.org/cgi/query-pr.cgi?pr=27495 1049 at the bottom for details on a workaround. The error message 1050 is 1051Updater failed: Cannot delete "/usr/ports/www/jakarta-tomcat/files": Directory not empty 1052 105320010520: 1054 Vm and/or swapping are busted on -current. Please be patient. 1055 105620010519: 1057 pccard has had much reorganizational work done to it over 1058 the past few days. Everything should still work, but if 1059 not, please contact imp@freebsd.org. 1060 106120010517: 1062 ata ioctl changed. Make sure to recompile both kernel and 1063 userland at the same time. 1064 106520010517: 1066 New ncurses imported. 1067 106820010512: 1069 DEVFS is now opt out, not opt in. Barring major problems, this 1070 will be the only way to go starting July 1. 1071 107220010504: 1073 OpenSSH has been updated to 2.9. Some defaults are different, 1074 including RhostsRSAAuthentication, which changes from yes to no. 1075 107620010502: 1077 Perl breakage in 20010501 was corrected at 14:18:33 PDT. 1078 107920010501: 1080 Building perl was broken at 02:25:25 PDT. 1081 108220010430: 1083 The bug in 20010429 was corrected at 07:35:37 PDT. It is safe to 1084 go back in the water. 1085 108620010429: 1087 A bad bug was committed at 04:48:42 PDT. Don't use kernels after 1088 this date, but before the correction date. 1089 109020010423: 1091 old fsck and new kernel interactions appear to have been fixed. 1092 109320010411: 1094 fsck and the kernel were changed to handle some optimizations 1095 to directory layout. This breaks backward compatibility. 1096 Update only if you understand that you must not use the old 1097 fsck with the new kernel ever. 1098 109920010330: 1100 fsck has changed the meaning of the pass column in /etc/fstab. 1101 Please see the cvs commit to fsck.8 or the fsck.8 man page for 1102 details. It is unclear if changes to /etc/fstab are necessary. 1103 110420010319: 1105 portmap had changed name to rpcbind for maximum POLA in your 1106 current world. /etc/hosts.{allow,deny} needs changes. nfs and 1107 other rpc based programs that rely on portmapper will not work 1108 without updates to /etc/hosts.{allow,deny} and /etc/netconfig. 1109 111020010315: 1111 ata subsystem changes. ATA_ENABLE_ATAPI_DMA, ATA_ENABLE_WC 1112 and ATA_ENABLE_TAGS are no longer kernel options. They have 1113 been replaced by tunables. See ata.4 for details. 1114 111520010312: 1116 The fxp driver was converted to use miibus. If you compile 1117 fxp into your kernel statically, you will need to add miibus. 1118 111920010312: 1120 The wi device now defaults to BSS (infrastructure) mode 1121 instead of ad-hoc. 1122 112320010310: 1124 /dev/urandom should be a symbolic link to /dev/random now. 1125 Users of current not using DEVFS need to run MAKEDEV std. 1126 ssh might not work if you don't. 1127 112820010303: 1129 The ed driver has been updated. It now allows mii attachments, 1130 which means that you must include the miibus in your kernel if 1131 you use the ed driver. 1132 113320010220: 1134 The problems with libc have been corrected. It is now mostly 1135 safe to go back into the water. 1136 113720010211: 1138 The size of FILE was changed. This breaks upgrading. If 1139 you must upgrade, be prepared for pain. It also breaks almost 1140 all binaries that you've compiled on -current. You are warned 1141 that before upgrading would be a good time to do a level 0 1142 dump of your system. No, really, I mean it this time. 1143 1144 To get to the new system, you'll need to use the following 1145 workaround. Hopefully this can be sorted out so that we 1146 don't have to move this to the updating section. 1147 1148 To get around the installworld problem, do: 1149 # cd /usr/src/usr.bin/sed 1150 # make install 1151 # cd /usr/src 1152 # make installworld 1153 If that doesn't work, then try: 1154 # make -k installworld 1155 # make installworld 1156 115720010207: 1158 DEVFS is now the default. If you use vinum, make sure that you 1159 do not include devfs in your kernel as problems result. 1160 116120010205: 1162 FFS_ROOT and CD9660_ROOT have been removed or deprecated. 1163 Remove them from your config. 1164 116520010122: 1166 ****************************** WARNING ****************************** 1167 buildkernel has been changed slightly 1168 ****************************** WARNING ****************************** 1169 KERNCONF replaces the variable KERNEL for buildkernel. You 1170 should update your scripts and make.conf accordingly. 1171 117220010119: 1173 config has changed to allow DEV_FOO as a replacement for NFOO. 1174 This requires a new config to build correctly. 1175 117620010116: 1177 The kernel option I386_CPU is now mutually exclusive with the 1178 other cpu types. If you have an i386 system, be sure that it 1179 only had this line. Remove it for all other configurations. 1180 118120010110: 1182 Changes to the kernel require it and burncd be in sync. 1183 118420010102: 1185 Everyone who has hw.sndunit set to something in 1186 /etc/sysctl.conf, it is now hw.snd.unit. 1187 118820010101: 1189 ex and vi were broken by some changes to sys/queue.h. If you 1190 have a bad vi, you will see make buildworld fail with a core 1191 dump while building termcap. You can work around this problem 1192 by adding -k to your make buildworld. This will cause the 1193 build to complete and install a new vi. Once that's done, you 1194 can rebuild again without the -k to pick up anything that 1195 might have been ignored by the -k option. 1196 1197 Others have suggested that you can just rebuild libc if your 1198 vi/ex is dynamically linked, but I've not received any reports 1199 of this working. 1200 120120001228: 1202 There have been some changes to libcrypt in -current. The 1203 libscrypt/libdescrypt symlink silliness is gone and the installed 1204 libcrypt is fully functional. Be aware of this. 1205 120620001218: 1207 Linksys Fast Ethernet PCCARD cards supported by the ed driver 1208 now require the addition of flag 0x80000 to their config line 1209 in pccard.conf(5). This flag is not optional. These Linksys 1210 cards will not be recognized without it. 1211 121220001205: 1213 Important new FreeBSD-version stuff: PAM support has been worked 1214 in, partially from the "Unix" OpenSSH version. This requires 1215 adding the following in pam.conf: 1216 1217 sshd auth sufficient pam_skey.so 1218 sshd auth required pam_unix.so try_first_pass 1219 sshd session required pam_permit.so 1220 122120001031: 1222 cvs updated to 1.11. 1223 122420001020: 1225 The random device needs more entropy, so you need to make sure 1226 that you've run mergemaster to get a /etc/rc which will seed 1227 /dev/random. If you don't and the system hangs after ldconfig, 1228 then banging on the keyboard randomly until it unhangs is one 1229 workaround. 1230 123120001010: 1232 ****************************** WARNING ****************************** 1233 Sendmail has been updated. 1234 ****************************** WARNING ****************************** 1235 o mail.local(8) is no longer installed as a set-user-id binary. 1236 o sendmail(8) is now built with STARTTLS support unless NO_OPENSSL 1237 is set. 1238 o The default /etc/mail/sendmail.cf disables the SMTP EXPN and VRFY 1239 commands. 1240 o Now using sendmail's version of vacation(1). 1241 o The sendmail cf building tools (contrib/sendmail/cf) are installed 1242 in /usr/share/sendmail/cf. 1243 o sendmail.cw changed to local-host-names 1244 1245 More details can be found at 1246 http://people.freebsd.org/~imp/UPDATING/sendmail-20001010 1247 124820001009: 1249 The ports tree's new layout is in place. Be sure to update 1250 your entire ports tree, or you will have problems. 1251 125220001006: 1253 The perl build procedure no longer installs miniperl, nor uses 1254 the installed miniperl. It is recommended that you delete 1255 /usr/bin/miniperl. 1256 125720001005: 1258 This weekend the ports tree will be updated to a new layout. 1259 It will be in an inconsistent state until noted in the UPDATING 1260 file, or with asami-san's message to the relevant mailing 1261 lists. With this new layout, you'll need to update the whole 1262 tree for anything to work. 1263 126420000928: 1265 There was a change in the passwd format. Need more information. 1266 126720000916: 1268 /boot/kernel/kernel.ko -> /boot/kernel/kernel change has taken 1269 place. Please update boot loader (not the boot blocks) at the 1270 same time as your kernel. 1271 127220000914: 1273 The new pmtimer device is necessary for laptops. Failure to 1274 include the device will cause suspended laptops losing time 1275 when they resume. Include 1276 device pmtimer 1277 in your config file and 1278 hint.pmtimer.0.at="isa" 1279 to your /boot/device.hints file. 1280 128120000911: 1282 The random device has been turned into a (pseudo-)device, 1283 rather than an option. The supplied kernel config files have 1284 been updated. You will need to do something similar in your 1285 own kernel config file. 1286 Remove: 1287 options RANDOMDEV 1288 Add: 1289 device random 1290 If you prefer to load the loadable module, you need to do 1291 nothing. 1292 129320000909: 1294 The random device module has been renamed from randomdev.ko to 1295 random.ko. You will need to edit your /boot/loader.conf to 1296 reflect this if you load this module at boot time. 1297 The line should read: 1298 random_load="YES" 1299 130020000907: 1301 The SMPNG commit has happened. It should work, but if it 1302 doesn't, fallback to the PRE_SMPNG CVS tag. There are likely 1303 to be a variety of minor issues. Please see 20000905 to make 1304 sure you don't have model loading problems which might at 1305 first blush appear related to SMP. 1306 130720000906: 1308 nsswitch has been imported from NetBSD. Among other things, 1309 this means that /etc/host.conf is no longer used. See 1310 nsswitch.conf(5) instead. Note that at boot time rc.network 1311 will attempt to produce a new nsswitch.conf file for you if you 1312 don't have one, and you have host.conf. 1313 131420000905: 1315 The ucred structure changed size. This breaks the interface 1316 that mountd uses. Trying to use an older mountd with a newer 1317 kernel guarantees a panic. This means that you need to use 1318 kernels newer than today only with matching mountd, but you 1319 needed to do that anyway with the boot loader changes. 1320 132120000905: 1322 The boot loader has been updated. The new default kernel is 1323 now /boot/kernel/kernel.ko. The new default module location 1324 is /boot/kernel. 1325 1326 You *MUST* upgrade your boot loader and kernel at the same time. 1327 The easiest way to do this is to do the buildworld/buildkernel/ 1328 installkernel/installworld dance. 1329 1330 Furthermore, you are urged to delete your old /modules directory 1331 before booting the new kernel, since kldload will find stale 1332 modules in that directory instead of finding them in the correct 1333 path, /boot/kernel. The most common complaint that this cures 1334 is that the linux module crashes your machine after the update. 1335 1336 if [ ! -d /boot/kernel.old ]; then 1337 mv /modules.old /boot/kernel.old 1338 chflags noschg /kernel.old 1339 mv /kernel.old /boot/kernel.old/kernel.ko 1340 chflags schg /boot/kernel.old/kernel.ko 1341 fi 1342 134320000904: 1344 A new issue with the sendmail upgrade has come to light. 1345 /etc/aliases has moved to /etc/mail/aliases. Mergemaster will 1346 incorrectly install the default aliases in /etc/mail rather than 1347 move the old one from /etc. So you'll need to manually move the 1348 file, create a symbolic link, remove the old /etc/aliases.db and 1349 run newaliases. For safety sake, you should stop sendmail 1350 while doing this and run the upgrade when locally sourced email 1351 is not likely to be generated. 1352 135320000825: 1354 /boot/device.hints is now required for installkernel to 1355 succeed. You should copy GENERIC.hints for your architecture 1356 into /boot/device.hints. If and only if you compile hints 1357 into your kernel, then this file may be empty. Please note, 1358 if you have an empty or missing /boot/device.hints file and 1359 you neglected to compile hints into your kernel, no boot 1360 messages will appear after the boot loader tries to start the 1361 kernel. 1362 136320000821: 1364 If you do NOT have ``options RANDOMDEV'' in your kernel and 1365 you DO want the random device then add randomdev_load="YES" to 1366 /boot/loader.conf. 1367 136820000812: 1369 suidperl is now always built and installed on the system, but 1370 with permissions of 511. If you have applications that use 1371 this program, you are now required to add ENABLE_SUIDPERL=true 1372 to /etc/make.conf. If you forget to do this, 1373 chmod 4511 /usr/bin/suidperl 1374 will fix this until the next build. 1375 137620000812: 1377 sendmail has been updated from 8.9.3 to 8.11.0. Some of the more 1378 visible changes that may immediately affect your configuration 1379 include: 1380 - New default file locations from src/contrib/sendmail/cf/README 1381 - newaliases limited to root and trusted users 1382 - MSA port (587) turned on by default 1383 - New queue file naming system so can't go from 8.11 -> 8.9 1384 - FEATURE(`rbl') renamed to FEATURE(`dnsbl') 1385 - FEATURE(`nullclient') is more full featured 1386 - FEATURE(`nouucp') requires an argument: `reject' or `nospecial' 1387 - mail.local FreeBSD-only -b option changed to -B 1388 - See src/contrib/sendmail/RELEASE_NOTES for more info 1389 139020000810: 1391 suidperl (aka sperl) is no longer build by default. You must 1392 specifically define BUILD_SUIDPERL to "true" for it to be build. 1393 Furthermore, we recommend that you remove /usr/bin/sperl* and 1394 /usr/bin/suidperl files from your system unless you have a 1395 specific use for it. 1396 139720000729: 1398 Networking defaults have been tightened. Anybody upgrading 1399 /etc/defaults/rc.conf needs to add the following lines to 1400 /etc/rc.conf if they want to have the same setup 1401 afterwards (unless the variables already are set, of course): 1402 # Enable network daemons for user convenience. 1403 inetd_enable="YES" 1404 portmap_enable="YES" 1405 sendmail_enable="YES" 1406 140720000728: 1408 If you have null_load="YES" in your /boot/loader.conf, you 1409 will need to change that to nullfs_load="YES". 1410 141120000728: 1412 The "installkernel" target has changed slightly. Now even if 1413 you override KERNEL e.g. 'make installkernel KERNEL=MYKERNEL' 1414 it will install the MYKERNEL file (built with the buildkernel 1415 target) as /kernel rather than /MYKERNEL. Those who have 1416 updated their /boot/loader.conf files to point to /MYKERNEL 1417 should remove that entry or perform manual rename of /kernel 1418 to /MYKERNEL. 1419 142020000711: 1421 If you use CVSUP or CTM to get CVS trees, AND you used to get 1422 the old crypto files from internat.freebsd.org AND you check 1423 out files from the CVS tree with the cvs command, please read 1424 http://people.freebsd.org/~imp/internat.txt 1425 for details on potential problems that you might have and how 1426 to get around them. 1427 1428 If you are merely a mirror, or don't answer yes to each of the 1429 clauses above, you needn't worry. 1430 143120000711: 1432 /etc/security has been updated to print the inode number of 1433 setuid programs that have changed. You will see a large spike 1434 in the number of changed programs the first time when you run 1435 mergemaster to get a new /etc/security. 1436 143720000710: 1438 /dev/random now has good entropy collection (from the keyboard 1439 and sysmouse drivers). Please ensure that either `options 1440 RANDOMDEV' is present in your kernel config file or that 1441 `randomdev_load="YES"' is in your /boot/loader.conf. If you do 1442 not have the /dev/random driver, OpenSSL (and consequently 1443 lots of crypto tools (like SSH)) will fail with strange 1444 errors. (see below, 20000624). 1445 1446 FreeBSD-current is safe again to run Crypto. 1447 144820000709: 1449 phk made the malloc default options AJ. This may slow things 1450 down and uncover other latent bugs in the code. If you need to 1451 run at full speed, you can disable this by doing the following: 1452 ln -s aj /etc/malloc.conf 1453 145420000706: 1455 libftpio's version was accidentally bumped a few days ago. This 1456 has been corrected. You may need to remove /usr/lib/libftpio.so.6 1457 before doing your next buildworld/installworld pair. It certainly 1458 won't hurt to remove it before the update procedure. It will 1459 break fetch until a new one is built, but ftp can be used in the 1460 interim if needed. 1461 146220000705: 1463 The crypto packages have changed for the cvsup. This has been done 1464 in a backward compatible way, but the old packages will go away at 1465 some point in the future. Look at /usr/share/examples/cvsup for 1466 details. 1467 146820000704: 1469 With the new sys/modules/sound/drivers/*, you will need to 1470 set SYSDIR until you do an installworld after July 7th. 1471 147220000704: 1473 rc.shutdown and rc will now call the rc.d scripts with start 1474 or stop. This may cause some harmless warnings from older 1475 rc.d scripts that haven't been updated. 1476 147720000630: 1478 The libfetch based version of fetch has gone into the tree. 1479 Minor problems may result on some of the less popular sites, 1480 which should be reported to des@freebsd.org. 1481 148220000625: 1483 From approximately this date forward, one must have the crypto 1484 system installed in order to build the system and kernel. 1485 While not technically strictly true, one should treat it as 1486 required and grab the crypto bits. If you are grabbing CVS 1487 trees, src-all and cvs-crypto should be treated as if they 1488 were required. You should check with the latest collections 1489 to make sure that these haven't changed. 1490 149120000624: 1492 Mark Murray just committed the first parts of a cleanup of 1493 /dev/zero, et al. This is also cleaning up /dev/random. 1494 The entropy is disconnected, so DO NOT USE VERSIONS OF FREEBSD 1495 -CURRENT FROM THIS POINT to 2000710 for cryptographic services 1496 until Mark can merge in the fixes to this work in progress. 1497 openssh and openssl should not be used to generate keys from this 1498 date to the completion of the work. 1499 1500 If you must operate at this reduced level of security, add ' 1501 options RANDOMDEV' to your kernel or modload the randomdev 1502 module. You may also need to copy a new MAKEDEV to /dev and 1503 recreate the random and urandom devices. 1504 150520000622: 1506 The license on the softupdates is now a standard 2 clause 1507 BSD license. You may need to remove your symbolic links 1508 that used to be required when updating. 1509 151020000621: 1511 Scott Flatman <sf@aracnet.com> sent in a decent write-up on 1512 the config file update procedure. 1513 http://people.freebsd.org/~imp/config-upd.html 1514 NOTE: LINT is gone. It has been replaced with NOTES. NOTES 1515 isn't buildable. However, you can generate a LINT file: 1516 cd /sys/<ARCH>/conf && make LINT 1517 151820000620: 1519 Binutils 2.10 have hit the tree, or will shortly. As soon 1520 as they do, the problem noted in 20000522 will be resolved and 1521 that workaround will no longer be required. 1522 152320000615: 1524 phk removed the compatibility creation of wd devices in the 1525 ad driver. If you haven't done so already, you must update 1526 your fstab, etc to use the ad devices instead of the wd 1527 devices. 1528 1529 In addition, you'll need to update your boot blocks to a 1530 more modern version, if you haven't already done so. Modern 1531 here means 4.0 release or newer (although older releases 1532 may work). 1533 153420000612: 1535 Peter took an axe to config(8). Be sure that you read his mail 1536 on the topic before even thinking about updating. You will 1537 need to create a /boot/device.hints or add a hints directive 1538 to your config file to compile them in statically. The format 1539 of the config file has changed as well. Please see GENERIC or 1540 NEWCARD for examples of the new format. 1541 1542 Indirectly, this also breaks USERCONFIG. Unless a newer entry 1543 says that it has been fixed, assume that must use the hints mechanism 1544 in the loader if you need to use a machine with very old ISA cards 1545 in it. 1546 154720000522: 1548 A new set of binutils went into the tree today. Anybody 1549 building a kernel after this point is advised that they need 1550 to rebuild their binutils (or better yet do a 1551 buildworld/installworld) before building a new kernel. 1552 1553 Due to bugs in binutils, using malloc options (eg /etc/malloc.conf 1554 or MALLOC_OPTIONS env var) J will cause ld to dump core. It 1555 is recommended that you don't set this option until the problem 1556 is resolved. 1557 155820000513: 1559 The ethernet drivers were all updated to clean up the BPF handling. 1560 156120000510: 1562 The problems with boot blocks on the alphas have been corrected. 1563 This will require some care in updating alphas. A new libstand 1564 is requires for the boot blocks to build properly. 1565 156620000503: 1567 Recompile all kld modules. Proper version dependency info 1568 is now available. 1569 157020000502: 1571 Modules have been disconnected from the buildworld tree and 1572 connected to the kernel building instead. 1573 157420000427: 1575 You may need to build gperf 1576 cd /usr/src/gnu/usr.bin/gperf && make depend all install 1577 when upgrading from 4.0 -> current. The build system now uses 1578 an option only in -current. 1579 158020000417: 1581 The method that we brand ELF binaries has changed to be more 1582 acceptable to the binutils maintainers. You will need to 1583 rebrand your ELF binaries that aren't native. One problem 1584 binary is the Linux ldconfig. After your make world, but 1585 before you reboot, you'll need to issue: 1586 brandelf -t Linux /compat/linux/sbin/ldconfig 1587 if you have Linux compatibility enabled on your machine. 1588 158920000320: 1590 If you have really bad/marginal IDE drives, you may find they 1591 don't work well. Use pio mode instead. The easiest way to 1592 cope if you have a problem combination is to add: 1593 /sbin/sysctl hw.ata.ata_dma=0 1594 to the start of /etc/rc.conf. 1595 159620000319: 1597 The ISA and PCI compatibility shims have been connected to the 1598 options COMPAT_OLDISA and COMPAT_OLDPCI. If you are using old 1599 style PCI or ISA drivers (i.e. tx, voxware, etc.) you must 1600 include the appropriate option in your kernel config. Drivers 1601 using the shims should be updated or they won't ship with 1602 5.0-RELEASE, targeted for 2001. 1603 160420000318: 1605 We've entered the traditional post release dumping party. 1606 Large kernel changes are being committed and are in the 1607 works. It is important to keep the systems' klds and kernel 1608 in sync as kernel interfaces and structures are changing. 1609 Before reporting kernel panics, make sure that all modules 1610 that you are loading are up to date. 1611 161220000315: 1613 If you are upgrading from an older version of FreeBSD, you 1614 need to update your boot blocks as well. 'disklabel -B ad0' 1615 will do the trick. This isn't critical until you remove your 1616 wd device entries in /dev, at which point your system will not 1617 boot. 1618 161920000315: 1620 4.0 RELEASE shipped. Please see the 4.0 UPDATING file for how 1621 to upgrade to 4.0 from 3.x. 1622 1623COMMON ITEMS: 1624 1625 # NOTE: 5.x below applies to 6.0-currrent as well, for the 1626 # momemnt. 4.any -> 5.any upgrade support will remain in 1627 # place for 6.0 current, but after 5.3 RELEASE, the 4.any -> 1628 # 6.0-current upgrade path will require moving through 5.3 1629 # RELEASE or newer. 1630 1631 General Notes 1632 ------------- 1633 Avoid using make -j when upgrading. From time to time in the 1634 past there have been problems using -j with buildworld and/or 1635 installworld. This is especially true when upgrading between 1636 "distant" versions (eg one that cross a major release boundary 1637 or several minor releases, or when several months have passed 1638 on the -current branch). 1639 1640 Sometimes, obscure build problems are the result of environment 1641 poisoning. This can happen because the make utility reads its 1642 environment when searching for values for global variables. 1643 To run your build attempts in an "environmental clean room", 1644 prefix all make commands with 'env -i '. See the env(1) manual 1645 page for more details. 1646 1647 To build a kernel 1648 ----------------- 1649 If you are updating from a prior version of FreeBSD (even one just 1650 a few days old), you should follow this procedure. With a 1651 /usr/obj tree with a fresh buildworld, 1652 make -DALWAYS_CHECK_MAKE buildkernel KERNCONF=YOUR_KERNEL_HERE 1653 make -DALWAYS_CHECK_MAKE installkernel KERNCONF=YOUR_KERNEL_HERE 1654 1655 To just build a kernel when you know that it won't mess you up 1656 -------------------------------------------------------------- 1657 This assumes you are already running a 5.X system. Replace 1658 ${arch} with the architecture of your machine (e.g. "i386", 1659 "alpha", "amd64", "ia64", "pc98", "sparc64", etc). 1660 1661 cd src/sys/${arch}/conf 1662 config KERNEL_NAME_HERE 1663 cd ../compile/KERNEL_NAME_HERE 1664 make depend 1665 make 1666 make install 1667 1668 If this fails, go to the "To build a kernel" section. 1669 1670 To rebuild everything and install it on the current system. 1671 ----------------------------------------------------------- 1672 # Note: sometimes if you are running current you gotta do more than 1673 # is listed here if you are upgrading from a really old current. 1674 1675 <make sure you have good level 0 dumps> 1676 <maybe fix /etc/fstab> [7] 1677 make buildworld 1678 make kernel KERNCONF=YOUR_KERNEL_HERE 1679 [1] 1680 <reboot in single user> [3] 1681 src/etc/rc.d/preseedrandom [10] 1682 mergemaster -p [5] 1683 make installworld 1684 mergemaster [4] 1685 <reboot> 1686 1687 1688 To cross-install current onto a separate partition 1689 -------------------------------------------------- 1690 # In this approach we use a separate partition to hold 1691 # current's root, 'usr', and 'var' directories. A partition 1692 # holding "/", "/usr" and "/var" should be about 2GB in 1693 # size. 1694 1695 <make sure you have good level 0 dumps> 1696 <boot into -stable> 1697 make buildworld 1698 <maybe newfs current's root partition> 1699 <mount current's root partition on directory ${CURRENT_ROOT}> 1700 make installworld DESTDIR=${CURRENT_ROOT} 1701 make buildkernel KERNCONF=YOUR_KERNEL_HERE 1702 cp src/sys/${ARCH}/conf/GENERIC.hints \ 1703 ${CURRENT_ROOT}/boot/device.hints # as needed 1704 make installkernel KERNCONF=YOUR_KERNEL_HERE DESTDIR=${CURRENT_ROOT} 1705 cd src/etc; make distribution DESTDIR=${CURRENT_ROOT} # if newfs'd 1706 cp /etc/fstab ${CURRENT_ROOT}/etc/fstab # if newfs'd 1707 <edit ${CURRENT_ROOT}/etc/fstab to mount "/" from the correct partition> 1708 <reboot into current> 1709 <do a "native" rebuild/install as described in the previous section> 1710 <maybe install compatibility libraries from src/lib/compat> 1711 <reboot> 1712 1713 1714 To upgrade in-place from 4.x-stable to current 1715 ---------------------------------------------- 1716 # 5.x uses more space than 4.x. Also, the location of kernel 1717 # modules has changed. If you are installing 5.x onto a 4.x 1718 # system, you'll need about 30MB of free disk space on your / 1719 # partition. If you have less than this, you may encounter difficult 1720 # to back out of problems with this procedure. If /tmp is on 1721 # the / partition, you may want to completely remove all its content 1722 # before upgrading, as this can be a common source of shortage of 1723 # space on /. 1724 1725 <make sure you have good level 0 dumps> 1726 <maybe fix /etc/fstab> [7] 1727 make buildworld [9] 1728 cp sys/${MACHINE}/conf/GENERIC.hints /boot/device.hints [2] 1729 make kernel KERNCONF=YOUR_KERNEL_HERE [8] 1730 cd sys/boot ; make STRIP="" install [6] 1731 [1] 1732 <reboot in single user> [3] 1733 src/etc/rc.d/preseedrandom [10] 1734 mergemaster -p [5] 1735 rm -rf /usr/include/g++ 1736 make installworld 1737 mergemaster -i [4] 1738 <reboot> 1739 1740 Make sure that you've read the UPDATING file to understand the 1741 tweaks to various things you need. At this point in the life 1742 cycle of current, things change often and you are on your own 1743 to cope. The defaults can also change, so please read ALL of 1744 the UPDATING entries. 1745 1746 Also, if you are tracking -current, you must be subscribed to 1747 freebsd-current@freebsd.org. Make sure that before you update 1748 your sources that you have read and understood all the recent 1749 messages there. If in doubt, please track -stable which has 1750 much fewer pitfalls. 1751 1752 [1] If you have third party modules, such as vmware, you 1753 should disable them at this point so they don't crash your 1754 system on reboot. 1755 1756 [2] If you have legacy ISA devices, you may need to create 1757 your own device.hints to reflect your unique hardware 1758 configuration. 1759 1760 [3] From the bootblocks, boot -s, and then do 1761 fsck -p 1762 mount -u / 1763 mount -a 1764 cd src 1765 adjkerntz -i # if CMOS is wall time 1766 Also, when doing a major release upgrade, it is required that 1767 you boot into single user mode to do the installworld. 1768 For the 4.x -> 5.x upgrade, you will also see many messages about 1769 needing to recompile your userland. These are harmless and can 1770 be ignored while you proceed to the next step. 1771 1772 [4] Note: This step is non-optional. Failure to do this step 1773 can result in a significant reduction in the functionality of the 1774 system. Attempting to do it by hand is not recommended and those 1775 that pursue this avenue should read this file carefully, as well 1776 as the archives of freebsd-current and freebsd-hackers mailing lists 1777 for potential gotchas. 1778 1779 [5] Usually this step is a noop. However, from time to time 1780 you may need to do this if you get unknown user in the following 1781 step. It never hurts to do it all the time. You may need to 1782 install a new mergemaster (cd src/usr.sbin/mergemaster && make 1783 install) after the buildworld before this step if you last updated 1784 from current before 20020224 or from -stable before 20020408. 1785 1786 [6] 4.x boot loader can be used to boot a 5.x system, however 1787 it is difficult to do that at best. If you wish to try, then 1788 you should interrupt the boot and at the ok prompt type: 1789 ok unload 1790 ok boot /boot/kernel/kernel 1791 If this fails to work, you must install a new boot loader as 1792 described here. 1793 1794 [7] Before you upgrade, please make sure that you are not using 1795 compatibility slices. These are device names of the form /dev/ad0a 1796 without the actual slice name. These will break with 5.x and newer. 1797 You generally must update these entries to use the post FreeBSD 1798 2.x form of /dev/ad0s1a. i386 and pc98 are affected, while alpha 1799 is not. 1800 1801 [8] In order to have a kernel that can run the 4.x binaries 1802 needed to do an installworld, you must include the COMPAT_FREEBSD4 1803 option in your kernel. Failure to do so may leave you with a system 1804 that is hard to boot to recover. 1805 1806 Make sure that you merge any new devices from GENERIC since the 1807 last time you updated your kernel config file. 1808 1809 [9] When checking out sources, you must include the -P flag to have 1810 cvs prune empty directories. 1811 1812 If CPUTYPE is defined in your /etc/make.conf, make sure to use the 1813 "?=" instead of the "=" assignment operator, so that buildworld can 1814 override the CPUTYPE if it needs to. 1815 1816 MAKEOBJDIRPREFIX must be defined in an environment variable, and 1817 not on the command line, or in /etc/make.conf. buildworld will 1818 warn if it is improperly defined. 1819 1820 In case you would like to avoid installing new packages of everything, 1821 you might want to uncomment the "COMPAT4X= YES" entry, so that 4.x 1822 compatibility libraries are built which should allow you to continue 1823 using your existing software for a while. Alternatively, you can 1824 install the misc/compat4x port. 1825 1826 [10] In order to create temporary files, /dev/random must be 1827 initialized by feeding data into it. src/etc/rc.d/preseedrandom 1828 takes care of this. 1829FORMAT: 1830 1831This file contains a list, in reverse chronological order, of major 1832breakages in tracking -current. Not all things will be listed here, 1833and it only starts on March 15, 2000. Updating files can found in 1834previous releases if your system is older than this. 1835 1836Copyright information: 1837 1838Copyright 1998-2004 M. Warner Losh.
