UPDATING revision 130074
1Updating Information for FreeBSD current users 2 3This file is maintained and copyrighted by M. Warner Losh 4<imp@village.org>. See end of file for further details. For commonly 5done items, please see the COMMON ITEMS: section later in the file. 6 7NOTE TO PEOPLE WHO THINK THAT FreeBSD 5.x IS SLOW: 8 FreeBSD 5.x has many debugging features turned on, in 9 both the kernel and userland. These features attempt to detect 10 incorrect use of system primitives, and encourage loud failure 11 through extra sanity checking and fail stop semantics. They 12 also substantially impact system performance. If you want to 13 do performance measurement, benchmarking, and optimization, 14 you'll want to turn them off. This includes various WITNESS- 15 related kernel options, INVARIANTS, malloc debugging flags 16 in userland, and various verbose features in the kernel. Many 17 developers choose to disable these features on build machines 18 to maximize performance. 19 2020040601: 21 The MIDI drivers have been removed. Until the new module-friendly 22 ones are merged, remove or comment out midi and seq from your 23 kernel configuration. 24 2520040423: 26 Due to a new option in ipfw (versrcreach) the ipfw(8) command 27 needs to be recompiled. Normal accept/reject rules without 28 options are not affected but those with options may break until 29 ipfw(8) is recompiled. 30 3120040420: 32 Due to changes in the callout ABI, kernels compiled after this 33 date may be incompatible with kernel modules compiled prior to 34 20040406. 35 3620040414: 37 The PCI bus power state stuff has been turned on. If this causes 38 problems for your system, please disable it using the tunable 39 hw.pci.do_powerstate=0. 40 4120040412: 42 The bulk of the pci problems have been fixed, although the floppy 43 drive is still broken. 44 4520040410: 46 A substantial update to the pci bus resource and power management 47 have been committed. Expect a bumpy ride for a few days until 48 the unanticipated problems have been resolved. 49 5020040409: 51 Due to changes in the the Yarrow initialization process, 52 /dev/random needs to be fed before operations requiring 53 temp files can succeed in single user mode. This includes 54 running "make installworld". /dev/random may be fed by running 55 "/etc/rc.d/initrandom start" or with 20040415 source by running 56 "/etc/rc.d/preseedrandom". 57 5820040322: 59 The debug.mpsafenet tunable controls whether the kernel Giant 60 lock is held across the lower levels of the network stack, and 61 by default is turned off. In the few days following 20040322, 62 the behavior of debug.mpsafenet will change such that this 63 tunable controls Giant over all levels of the network stack. 64 If you are currently setting debug.mpsafenet to 1, you should 65 set it back to 0 (the default) again during the change-over. 66 An additional note will be added to UPDATING when sufficient 67 locking is merged to permit this to take place. 68 6920040310: 70 The FreeBSD/sparc64 platform is changing time_t from 32-bits to 71 64-bits. This is a very major incompatible change, so people 72 using FreeBSD/sparc64 *must* read the UPDATING.64BTT file for 73 detailed instructions on how to make this upgrade. People 74 upgrading FreeBSD on other platforms can ignore this event. 75 7620040308: 77 The packet filter (pf) is now installed with the base system. Make 78 sure to run mergemaster -p before installworld to create required 79 user account ("proxy"). If you do not want to build pf with your 80 system you can use the NO_PF knob in make.conf. 81 Also note that pf requires "options PFIL_HOOKS" in the kernel. The 82 pf system consists of the following three devices: 83 device pf # required 84 device pflog # optional 85 device pfsync # optional 86 8720040303: 88 If you are having trouble with the libc_r -> libpthread transition 89 (see the 20040130 entry), place the following lines at the top of 90 /etc/libmap.conf: 91 92 libc_r.so.5 libpthread.so.1 93 libc_r.so libpthread.so 94 95 This will cause all programs and libraries linked against libc_r 96 to use libpthread instead. 97 9820040226: 99 Some sshd configuration defaults have changed: protocol version 1 100 is no longer enabled by default, and password authentication is 101 disabled by default if PAM is enabled (which it is by default). 102 OpenSSH clients should not be affected by this; other clients may 103 have to be reconfigured, upgraded or replaced. 104 10520040225: 106 The ABIs defined in <resolv.h> and <netdb.h> have been updated 107 to support improved reentrancy. Multi-threaded programs that 108 reference the "_res" or "h_errno" symbols may experience some 109 problems if they are not recompiled. Single-threaded programs 110 should remain unaffected. 111 11220040225: 113 routed has been updated in the base system from the vendor 114 sources, routed v2.27, from rhyolite.com. This change means that 115 for users who use RIP's MD5 authentication feature, FreeBSD 116 -CURRENT's routed is now incompatible with previous versions 117 of FreeBSD; however it is now compatible with implementations 118 from Sun, Cisco and other vendors. 119 12020040224: 121 The tcpcb structure has changed and makes a recompile of libkvm 122 and related userland network utilities neccessary. 123 12420040222: 125 The cdevsw structure has changed in two externally visible ways. 126 First, the sense of the D_GIANT flag has changed to D_NEEDSGIANT. 127 Second, the d_version field must be filled in with D_VERSION. 128 Drivers outside the tree will need to be updated. 129 13020040207: 131 The /etc/rc.d/ttys script has been removed. It is no longer 132 necessary since devfs has been mandatory for some time. 133 13420040130: 135 libkse has been renamed back to libpthread and is now the 136 default threads library. The gcc -pthread option has also 137 been changed to link to libpthread instead of libc_r. For 138 alpha and sparc64 machines, libkse is not renamed and links 139 are installed so that libpthread points to libc_r. Until 140 the ports system is updated to handle this change, it is 141 recommended that folks install an /etc/libmap.conf(5) that 142 maps libc_r to libpthread. If you have any binaries or 143 libraries linked to libkse, then it is also recommended 144 that you map libkse to libpthread. Anyone that is using 145 nvidia supplied drivers and libraries should use a libmap.conf 146 that maps libpthread to libc_r since their drivers/libraries 147 do not work with libpthread. 148 14920040125: 150 ULE has entered into its probationary period as the default scheduler 151 in GENERIC. For the average user, interactivity is reported to be 152 better in many cases. On SMP machines ULE will be able to make more 153 efficient use of the available parallel resources. If you are not 154 running it now, please switch over, replacing the kernel option 155 SCHED_4BSD with SCHED_ULE. 156 15720040125: 158 Move LongRun support out of identcpu.c, where it hardly 159 belongs, into its own file and make it opt-in, not mandatory, 160 depending on CPU_ENABLE_LONGRUN config(8) option. 161 16220031213: 163 src/lib/libc/gen/initgroups.c:1.8 now causes logins to fail 164 if the login process is unable to successfully set the 165 process credentials to include all groups defined for the 166 user. The current kernel limit is 16 groups; administrators 167 may wish to check that users do not have over 16 groups 168 defined, or they will be unable to log in. 169 17020031203: 171 The ACPI module has been reactivated. It is no longer required 172 to compile ACPI support into kernels statically. 173 17420031112: 175 The statfs structure has been updated with 64-bit fields to 176 allow accurate reporting of multi-terabyte filesystem 177 sizes. You should build world, then build and boot the new kernel 178 BEFORE doing a `installworld' as the new kernel will know about 179 binaries using the old statfs structure, but an old kernel will 180 not know about the new system calls that support the new statfs 181 structure. 182 Note that the backwards compatibility is only present when the 183 kernel is configured with the COMPAT_FREEBSD4 option. Since 184 even /bin/sh will not run with a new kernel without said option 185 you're pretty much dead in the water without it. Make sure you 186 have COMPAT_FREEBSD4! 187 Running an old kernel after a `make world' will cause programs 188 such as `df' that do a statfs system call to fail with a bad 189 system call. Marco Wertejuk <wertejuk@mwcis.com> also reports 190 that cfsd (ports/security/cfs) needs to be recompiled after 191 these changes are installed. 192 193 ****************************DANGER******************************* 194 195 DO NOT make installworld after the buildworld w/o building and 196 installing a new kernel FIRST. You will be unable to build a 197 new kernel otherwise on a system with new binaries and an old 198 kernel. 199 20020031112: 201 Some netgraph string length constants have been changed. This 202 change requires the netgraph kernel modules and all netgraph 203 userland components to be in sync. Especially users who require 204 netgraph to boot need to make sure to have world and kernel in 205 sync before rebooting. 206 20720031111: 208 Hyperthreading logical CPU's are no longer probed by default 209 when using the MP Table. If ACPI is being used, then logical 210 CPUs will be probed if hyperthreading is enabled in the BIOS. 211 If ACPI is not being used and hyperthreading is enabled in the 212 BIOS, logical CPUs can be enabled by building a custom kernel 213 with the option MPTABLE_FORCE_HTT enabled. 214 21520031103: 216 The i386 APIC_IO kernel option has been replaced by 217 'device apic'. The ACPI module has also been temporarily 218 disabled, so ACPI must be statically compiled into your 219 kernel using 'device acpi' if you wish to use the ACPI driver. 220 22120031031: 222 The API and ABI of struct ifnet have been changed by removing 223 the if_name and if_unit members and replacing them with 224 if_xname, if_dname, and if_dunit. All network drivers and most 225 userland programs which include net/if_var.h must be updated 226 and recompiled. __FreeBSD_version has been bumped to 501113 to 227 reflect this change. 228 22920030928: 230 Changes to the cdevsw default functions have been made to remove 231 the need to specify nullopen() and nullclose() explicitly. 232 __FreeBSD_version bumpted to 501110. 233 23420030926: 235 kiconv(3) has been added. mount_msdosfs(8), mount_ntfs(8) and 236 mount_cd9660(8) need to be in sync with kernel. 237 23820030925: 239 Configuring a system to use IPFILTER now requires that PFIL_HOOKS 240 also be explicitly configured. Previously this dependency was 241 magically handled through some cruft in net/pfil.h; but that has 242 been removed. Building a kernel with IPFILTER but not PFIL_HOOKS 243 will fail with obtuse errors in ip_fil.c. 244 24520030923: 246 Fix a bug in arplookup(), whereby a hostile party on a locally 247 attached network could exhaust kernel memory, and cause a system 248 panic, by sending a flood of spoofed ARP requests. See 249 FreeBSD-SA-03:14.arp. 250 25120030915: 252 A change to /etc/defaults/rc.conf now causes inetd to be started 253 with `-C 60' if it is not overridden in /etc/rc.conf. This 254 causes inetd to stop accepting connections from an IP address 255 that exceeds the rate of 60 connections per minute. 256 25720030829: 258 The following rc.d scripts have been removed and should be 259 deleted from your installation: atm2.sh atm3.sh devdb 260 localdaemons network1 network2 network3. Depending on when 261 you last updated world and used mergemaster(8) you may or 262 may not have problems during the rc boot sequence. The simplest 263 solution is an 'rm -rf /etc/rc.d/*' and then 'mergemaster -i'. 264 The atm2.sh atm3.sh and devdb scripts were removed some time 265 ago, so depending on when you installed -CURRENT these scripts 266 may or may not exist on your system. 267 26820030824: 269 ATAng has been committed. You need to build world as sys/ata.h 270 has changed, and userland atacontrol depends on it. 271 If you use ATA SW raids you need "device ataraid" in your 272 kernel config file, as it is no longer pulled in automatically. 273 27420030819: 275 The OFW_NEWPCI option has been turned on in the Sparc64 GENERIC kernel. 276 Among other things, this changes the device enumeration to be 277 closer to Solaris. Be aware that, this can even cause the machine 278 to not boot without manual intervention before the fstab is adjusted. 279 28020030728: 281 All current USB and Firewire quirks in da(4) have been deprecated 282 and will be removed for 5.2. If this causes failure for your 283 umass(4) devices, enable "options DA_OLD_QUIRKS" in your kernel 284 and send the output of "camcontrol inquiry da0" to scsi@freebsd.org 285 so the quirk can be re-enabled. 286 28720030724: 288 Problems with entry 20030714 have been corrected and no known issues 289 with /rescue and -j exist for host systems after this point in time. 290 29120030722: 292 FPU-less support has been removed from FreeBSD. Chances are you won't 293 notice. 386+387 support should still work after this change, but 294 it is now a minimum requirement for the i386 port that you have real 295 FPU hardware. 296 29720030714: 298 Some people are having problems with changes related to /rescue. 299 If you are building -j N, you will need to define NO_RESCUE. Others 300 will need to define it if /rescue has issues with their environment. 301 People should report those issues to current@. 302 30320030711: 304 gcc was upgraded to 3.3. You are advised to not build -DNOCLEAN 305 across this point. Further, it might be a good idea to remove 306 /usr/obj. 307 30820030610: 309 Remove deprecated locale names and transition period code 310 for them, finishing switching to the new scheme. Check your 311 LANG environment variable. 312 31320030609: 314 CCD has been changed to be a fully GEOMified class. Kernel 315 and ccdconfig(8) needs to be in sync, this is particularly 316 important to remember beforehand if your source tree is on 317 a ccd device. Consider making a copy of the old ccdconfig 318 into /boot/kernel.good or wherever you keep your backup 319 kernel. 320 32120030605: 322 There was a small window in which sed(1) was broken. If you 323 happen to have sed(1) installed during that window, which is 324 evidenced by an inability to build world with the failure 325 given below, you need to manually build and install sed(1) 326 (and only sed(1)) before doing anything else. This is a one- 327 time snafu. Typical failure mode: 328 329 In file included from /usr/src/contrib/binutils/bfd/targets.c:1092: 330 targmatch.h:7:1: null character(s) ignored 331 targmatch.h:12:1: null character(s) ignored 332 targmatch.h:16:1: null character(s) ignored 333 : 334 335 The window of "sed(1)-uction" is from Wed Jun 4 15:31:55 2003 UTC 336 to Thu Jun 5 12:10:19 2003 UTC (from rev 1.30 to rev 1.31 of 337 usr.bin/sed/process.c). 338 33920030505: 340 Kerberos 5 (Heimdal) is now built by default. Setting 341 MAKE_KERBEROS5 no longer has any effect. If you do NOT 342 want the "base" Kerberos 5, you need to set NO_KERBEROS. 343 34420030502: 345 groff has been updated. If you try to do a buildworld and 346 get an infinite loop in troff, update to May 4th or newer. If you 347 have a newer kernel than userland, you may need to set the OSRELDATE 348 to 500110 in your environment before starting a buildworld. 349 35020030501: 351 The old rc system has been removed. Please report any problems 352 to freebsd-rc@yahoogroups.com, and/or freebsd-current@freebsd.org. 353 Your personal versions of these files will not be removed, so you can 354 continue to use them. However, you should take great care when updating, 355 especially when using mergemaster, since the compatibility code that 356 utilizes these old scripts has also been removed. 357 35820030423: 359 A bug has been fixed in /dev/devctl which would cause devd 360 to hang on boot, were it not for a workaround in devd. The 361 work around in devd will be removed around 20030507. You 362 have until then to upgrade your kernel before updating 363 userland. In general, you should have a userland and 364 kernel that's in sync with each other. However, given the 365 effects of this bug (hang on boot when starting devd), some 366 allowances are made. 367 36820030329: 369 Alphas with libc from between 20030312 and 20030329 exhibit 370 floating point exceptions (FPEs), most notably in awk(1) 371 while upgrading the system through a buildworld. 372 373 So, to successfully upgrade your Alpha, you must either 374 downgrade your libc.so to a pre-20030312 version, or update 375 /usr/share/mk/bsd.cpu.mk to revision 1.26 which adds -mieee 376 to CFLAGS, then forcibly rebuild and install libc: 377 378 cd /usr/src/lib/libc && \ 379 make cleandir && make obj && \ 380 make -DNOMAN -DNOPROFILE all && \ 381 make -DNOMAN -DNOPROFILE install 382 38320030208: 384 sendmail 8.12.7 has been imported. It has one important 385 change for IPv6 users. The default submit.mc now uses 386 '[127.0.0.1]' instead of 'localhost' meaning only IPv4 is 387 used to connect to the MTA. Users on IPv6-only machines 388 will need to edit /etc/mail/submit.mc appropriately. 389 39020030128: 391 NODEVFS option has been removed and DEVFS thereby made standard. 392 This makes all references to MAKEDEV obsolete, and they should 393 be removed when convenient. 394 39520030126: 396 The name of the device for the ofw console has changed, sparc64 users 397 must run mergemaster to update their installed /etc/ttys. 398 39920030125: 400 The scheduler framework has grown a second scheduler and consequently 401 you must specify one and only one scheduler in your kernel config. 402 The cvs config files have been updated to use the old scheduler 403 which may be selected via 'options SCHED_4BSD'. If you would like 404 to try the new, much more experimental, scheduler please try 405 'options SCHED_ULE' and contribute to the arch@ discussion. 406 40720030115: 408 A new version of the wi driver has been imported into the tree. 409 One now must have device wlan in the config file for it to operate 410 properly. 411 412 In addition, there have been some changes to how wi devices are 413 configured for point to point links to bring it more in line 414 with the former way of doing things, as well as compatibility 415 with NetBSD. 416 41720021222: 418 For a period after the GCC 3.2.1 import (from 12/04 to 12/22), GCC 419 used an incompatible form of ABI for returning structures and unions 420 which FreeBSD's GCC maintainers were not aware of relative to previous 421 versions of FreeBSD. We have gone back to the ABI for now, and any 422 code compiled which is required to interoperate with other code (not 423 built at the same time) returning structs or unions should be 424 rebuilt. 425 42620021216: 427 A name change in /etc/netconfig has been reverted to stay 428 compatible with suns TIRPC and also with NetBSD. You need 429 to run mergemaster after make world. A new libc does still work 430 with an outdated /etc/netconfig for some time, but you'll get 431 a warning. This warning will be removed in 20030301. 432 43320021202: 434 The recent binutils upgrade marks a kernel flag day on 435 sparc64: modules built with the old binutils will not work 436 with new kernels and vice versa. Mismatches will result in 437 panics. Make sure your kernel and modules are in sync. 438 43920021029: 440 The value of IPPROTO_DIVERT has changed. Make sure to keep 441 your kernel, netstat, natd and any third-party DIVERT 442 consumers in sync. 443 44420021024: 445 Old, compatibility slices have been removed in GEOM kernels. 446 This means that you will have to update your /etc/fstab to 447 not use disk devices of the form /dev/ad0a. Instead, you 448 now must specify /dev/ad0s1a, or whatever slice your FreeBSD 449 partition really is on. The old device names have gone 450 away, so if you use them anywhere else, you must also adjust 451 those uses. (This doesn't affect the disks formatted in 452 the ``dangerously-dedicated'' mode.) 453 45420021023: 455 Alphas with kernels from between 20020830 and 20021023 and/or 456 rtld (ld-elf.so.1) older than 20021023 may experience problems 457 with groff while doing a buildworld (kernel: "out of memory", 458 fixed in rev 1.129 of kern/imgact_elf.c; rtld: "too few PT_LOAD 459 segments", fixed in rev 1.8 of libexec/rtld-elf/map_object.c). 460 461 So, to successfully upgrade your Alpha, you must either 462 upgrade your kernel and rtld first (which might be a bit 463 tricky), or avoid running the bootstrapped groff during the 464 "transitional" buildworld. To avoid running groff during the 465 transitional upgrade run make buildworld with -DNOMAN, 466 -DNO_SHAREDOCS, and -DNO_LPR. 467 46820020831: 469 gcc has been upgraded to 3.2. It is not all binary compatible 470 with earlier versions of gcc for c++ programs. All c++ 471 programs and libraries need to be recompiled. 472 473 Also, if you encounter g++ issues, rm /usr/include/g++/* before 474 doing an installworld to make sure that stale files are removed. 475 47620020827: 477 Our /etc/termcap now has all the entries from the XFree86 xterm 478 almost unchanged. This means xterm now supports color by default. 479 If you used TERM=xterm-color in the past you now should use 480 TERM=xterm. (xterm-color will lead to benign warnings). 481 48220020815: 483 A "bug" in gcc(1) that was hiding warning in system headers was 484 fixed. It's probably time to add -DNO_WERROR to your make line 485 again. 486 48720020729: 488 COPY is being deprecated. The 20010530 change was reverted, as 489 it causes far more pain than was expected, and to always compare 490 before installing, please use INSTALL="install -C" again. The 491 -C option is now silently ignored when used with the -d option. 492 49320020702: 494 Problems with libc_r clients like KDE and GNOME have been resolved. 495 There are still some minor problems with some signals but the 496 system is stable enough for general use again. SMP is less so than UP 497 but each can successfully complete multiple buildworlds. 498 Libkvm needs to be recompiled due to KSE. 499 50020020701: 501 Now would be a bad time to upgrade. Something in or near the 502 KSE commit totally broke programs using libc_r like KDE and 503 GNOME. 504 50520020511: 506 The k5su utility installed as part of Kerberos 5 is no longer 507 installed with the set-user-ID bit set by default. Add 508 ENABLE_SUID_K5SU=yes to /etc/make.conf to have it installed 509 with the set-user-ID bit set. 510 51120020510: 512 Gcc 3.1 debugging format (cc -g) has changed from STABS to DWARF2. 513 Unfortunately our native GDB (at version 4.18) does not understand 514 the DWARF2 debugging format. Thus you must use `gcc -gstabs+' to 515 generated debugging information for our native GDB. 516 51720020510: 518 Due to the way CVS works, it may not properly update src/contrib/gcc 519 to the 3.1 sources. The easiest fix is to `rm -rf' src/contrib/gcc 520 and then do a cvs update. 521 52220020421: 523 When exec'ing set[ug]id executables, the kernel now ensures that the 524 stdio file descriptors (0..2) are open. See FreeBSD-SA-02:23.stdio. 525 52620020404: 527 New sendmail startup scripts have been installed to make it 528 easier to use alternative MTAs with FreeBSD. Setting the rc.conf 529 variable sendmail_enable to "NO" no longer prevents any sendmail 530 daemons from starting. Instead, either set sendmail_enable to 531 "NONE" or change mta_start_script to a script for starting 532 an alternative MTA. Setting mta_start_script to "" will 533 also prevent any MTA from being started at boot. 534 53520020403: 536 UCONSOLE is no longer a valid kernel option. 537 53820020315: 539 FreeBSD 5.0 DP-1 was basically branched today. 540 54120020225: 542 Warnings are now errors in the kernel. Unless you are a developer, 543 you should add -DNO_WERROR to your make line. 544 54520020217: 546 sendmail 8.12.2 has been imported. The sendmail binary is no 547 longer a set-user-ID root binary and the infrastructure to support 548 command line mail submission has changed. Be sure to run 549 mergemaster (especially for updating /etc/rc, /etc/defaults/rc.conf, 550 and /etc/mail) and read /etc/mail/README for more details. 551 552 Due to the import of sendmail 8.12.2, a new user and group are 553 required in order for sendmail to run as a set-group-ID 554 binary. A 'make installworld' will use the new user and group 555 to set the owner and group of /var/spool/clientmqueue and will 556 fail if the new user and group do not exist. The 'smmsp' user 557 and group must be merged from src/etc/group and 558 src/etc/master.passwd before using 'make installworld'. 559 'mergemaster -p' will do this. You may need to install 560 mergemaster before this will work if you are updating from a 561 very old version of current. The updating recipe has changed 562 as of this date. 563 56420020112: 565 The preferred configuration method for PAM is now /etc/pam.d/ 566 rather than /etc/pam.conf. If you have an unmodified 567 pam.conf, just delete it after your next mergemaster run. If 568 you have local modifications, you can use 569 /usr/src/etc/pam.d/convert.pl to incorporate them into your 570 /etc/pam.d. 571 572 Please see the following url for more details: 573http://www.freebsd.org/cgi/mid.cgi?db=mid&id=<xzp6667fyoa.fsf@flood.ping.uio.no> 57420011229: 575 If anyone here is already using the new rc.conf(5) variable 576 networkfs_types, please note that it has changed 577http://www.freebsd.org/cgi/mid.cgi?db=mid&id=<9744.1009655556@axl.seasidesoftware.co.za> 578 57920011220: 580 sys/i4b/driver/i4b_ispppsubr.c has been retired. This file 581 started out its life in the ISDN4BSD project as an offspring 582 from sys/net/if_spppsubr.c, which eventually got a life of its 583 own. All the accumulated features and bugfixes of the i4b 584 version have now been merged back into the base system's 585 version now. The only user-visible change resulting from this 586 is that i4b's sppp(4) interfaces are to be managed with 587 spppcontrol(8) again, since ispppcontrol(8) has been retired 588 as well. (There has never been rc file support for 589 ispppcontrol in -current, but only in -stable. That will be 590 reverted by the time the changes are MFCed.) 591 59220011215: 593 The fdc(4) driver has been updated and now automatically 594 recognizes media in `standard' formats (like 1440 KB and 595 720 KB for a 3.5" high-density drive) when accessing the 596 default device node (e. g. /dev/fd0). The old variety of 597 floppy device nodes /dev/fd*.* is no longer present by 598 default, devices can be created (in DEVFS) on demand. They 599 will need to be customized then for `odd' densities using 600 fdcontrol(8). 601 60220011209: 603 The bugs in procfs' debugging support code have been fixed, 604 and truss(1) now works again. 605 60620011207: 607 Daily security checks have been split out to use the periodic(8) 608 scripts. Some change in configuration may be necessary. Please 609 see 610http://www.freebsd.org/cgi/mid.cgi?db=mid&id=<20011207155805.R8975@blossom.cjclark.org> 611 for details. 612 61320011204: 614 sos added VCD/SVCD support to ata driver and that needs the 615 kernel and burncd to be in sync. 616 61720011203: 618 The procfs pseudo-filesystem has now been converted to use the 619 pseudofs framework. If you have 'options PROCFS' in your 620 kernel config, you'll need to add 'options PSEUDOFS' if it's 621 not there already. 622 623 This change temporarily breaks truss(1); use ktrace(1) instead 624 until the issue has been resolved. 625 62620011202: 627 A security hole in OpenSSH involving `UseLogin yes' has been 628 patched. 629 63020011126: 631 You need to remove /usr/obj/.../usr.bin/tip before rebuilding 632 after this date. You need to do this only once. 633 63420011103: 635 Most of the awk issues have been resolved. Some rough 636 edges may be left, but for the most part things should be 637 back to "normal." For CURRENT's usual definition of "normal." 638 63920011030: 640 Awk has been upgraded to the one true awk from bell labs. Expect 641 choppy waves in the upgrade process. 642 64320011030: 644 The asr driver problem has been resolved. 645 64620011027: 647 Due to changes in other parts of the system, the asr driver 648 now causes the system to panic on boot. Do not use it pending 649 correction. Comment it out of any kernel config file that you 650 try to use from this date forward. 651 65220011025: 653 When crossbuilding, use TARGET=xxx where you used to use 654 MACHINE=xxx. You don't need to set TARGET_ARCH and TARGET, 655 unless you are changing both of them. To cross build pc98 on 656 an alpha, for example, you need to set TARGET=pc98 and 657 TARGET_ARCH=i386. 658 65920011001: 660 The kernel interface that burncd depends on has changed. 661 You must recompile both the kernel and userland applications 662 at the same time. 663 66420010929: 665 When crossbuilding, please set TARGET_ARCH rather than 666 MACHINE_ARCH to indicate the target. In the future, one will 667 set TARGET_MACHINE where you set MACHINE now. At the moment, 668 setting MACHINE alone for same MACHINE_ARCH machines works 669 (eg, you can build pc98 on an i386 machine and vice versa). 670 67120010927: 672 Some weird problems result from using ACPI on some machines. 673 To disable ACPI you can add 674 hint.acpi.0.disabled="1" 675 to /boot/loader.conf (or by putting set X=Y at the boot 676 loader "ok" prompt). 677 678 Alternatively, you can remove it from /boot/kernel/acpi.ko 679 or use the MODULES_OVERRIDE function in your kernel config 680 file and not list acpi in that list. 681 68220010924: 683 The buildworld has been fixed. You may need to install 684 the 4.x compatibility libraries for some old binaries 685 to work. Add COMPAT4X=true to your /etc/make.conf to 686 get them installed on every installworld, or execute the 687 following to get them installed only once: 688 cd src/lib/compat/compat4x.<arch> 689 make all install 690 You will see ``__stdoutp undefined'' until you do this. 691 69220010919: 693 There's a bug in the world build process. The cross-tools 694 are build with the NEW headers, but the OLD libc.a. This 695 leads to all kinds of problems with the new libc. A temporary 696 workaround is to add 697 CFLAGS="-O -pipe -D_OLD_STDIO" 698 before building world when upgrading from 4.x to current. This 699 can be removed afterwards. 700 701 A proper fix to the buildworld target is needed. 702 70320010918: 704 Peter has committed his new kthread nfs client/server code. 705 NFS may be unstable after this date. 706 70720010912: 708 KSE has hit the tree. Lots of things are now different in 709 the kernel. While a few problems were introduced in the 710 initial commit, most of the major ones have been found and 711 corrected. 712 71320010901: 714 In OLDCARD, CardBus bridges appear to be stable. The work 715 arounds described in the 20010604 entry are now no longer 716 necessary and will be ignored. Most insert/remove problems 717 have been rectified around this date. 718 71920010823: 720 named now runs as user bind and group bind rather than as 721 root. If named_enable is set to YES in /etc/rc.conf, ensure 722 that user bind is available in /etc/passwd (using vipw(8)) 723 and that group bind is available in /etc/group. Also make 724 sure that user or group bind has read (and not write) 725 permission for your name server configuration and that it 726 has read and write permission for your slave zone files and 727 directory. 728 729 If you wish to continue to run named as root (a less secure 730 alternative), add a line to /etc/rc.conf saying 731 732 named_flags= 733 73420010709: 735 The PAM libraries have had an API upgrade that is beyond 736 the ability of the shared library major number to handle. 737 It is manifested by PAM-using ports dumping core. The 738 solution is to rebuild those ports. 739 74020010628: 741 The kernel compile module has moved from src/sys/compile/FOO 742 to src/sys/${MACHINE}/compile/FOO. 743 74420010625: 745 The pccard modem issue from 20010613 has been corrected. 746 OLDCARD support is still a little weak in -current. slot 1 is 747 known not to work on some TI based cardbus bridges. Some 748 cardbus bridges do not properly detect insert/removal events. 749 IRQ configuration needs more safety belts. 750 75120010617: 752 Softupdates problems have been corrected. 753 75420010614: 755 Peter ripped out the linkerset support. You must, as always, 756 rerun config after you cvsup if you are using the traditional 757 kernel building methods. 758 75920010613: 760 pccard modems may not work with current after 20010604 date. Some 761 do, others result in panics. *MAKE*SURE* that you update your 762 config and /etc/rc.conf ala the 20010604 entry, or you will have 763 problems (this issue will be fixed, it just hasn't been yet). 764 76520010613: 766 SOFTUPDATES seem to be broken since the middle of May or so. Do not 767 use them in current. You can disable softupdates on all mounted 768 partitions, or remove SOFTUPDATES the kernel config file. 769 77020010612: 771 After Peter's commits to the hints code, people have been noticing 772 that certain devices are attached (or try to) twice. This is due 773 to having both static hints as well as a /boot/device.hints. To 774 work around this issue, please use only one or the other mechanism 775 until this bug is fixed. 776 777 Please note that a feature of config is that if you have config 778 file FOO and FOO.hints, it automatically adds FOO.hints to the 779 hints.c file, whether you want it to or not. 780 78120010610: 782 Locale names have changed to match other systems better. 783 78420010604: 785 pccard support for pci cards has been committed. You must change 786 your /etc/pccard.conf irq lines. It must match the irq used by 787 pcic device. Interrupt storms may result if you fail to do this. 788 Interrupt storms look a lot like a hang. 789 790 You must also install a new pccardd, otherwise you will get an 791 interrupt storm at card reset time (just after it tells you what 792 it is). 793 794 pccardd_flags="-I" is necessary for the time being. It tells pccardd 795 not to ask the kernel if the interrupt is really free or not before 796 using it. You can either change the /etc/pccard.conf irq lines to 797 match pcic, or add "-i X" to the pccardd_flags. 798 79920010530: 800 INSTALL=install -C is being deprecated. If you want to do this, 801 use COPY=-C instead. The former method will be supported for only 802 a limited time. If you see 803 804install: warning: the -d and -C options may not be specified together 805 806 in your makeworld, then you need to migrate towards using 807 COPY=-C. 808 80920010525: 810 It appears that vm is now stable enough to use again. However, 811 there may be other problems, so caution is still urged. alpha 812 definitely is in bad shape. 813 81420010521: 815 Minor repo damage has happened. This may cause problems 816 with cvsup of ports. If you get errors, please see 817 http://www.FreeBSD.org/cgi/query-pr.cgi?pr=27495 818 at the bottom for details on a workaround. The error message 819 is 820Updater failed: Cannot delete "/usr/ports/www/jakarta-tomcat/files": Directory not empty 821 82220010520: 823 Vm and/or swapping are busted on -current. Please be patient. 824 82520010519: 826 pccard has had much reorganizational work done to it over 827 the past few days. Everything should still work, but if 828 not, please contact imp@freebsd.org. 829 83020010517: 831 ata ioctl changed. Make sure to recompile both kernel and 832 userland at the same time. 833 83420010517: 835 New ncurses imported. 836 83720010512: 838 DEVFS is now opt out, not opt in. Barring major problems, this 839 will be the only way to go starting July 1. 840 84120010504: 842 OpenSSH has been updated to 2.9. Some defaults are different, 843 including RhostsRSAAuthentication, which changes from yes to no. 844 84520010502: 846 Perl breakage in 20010501 was corrected at 14:18:33 PDT. 847 84820010501: 849 Building perl was broken at 02:25:25 PDT. 850 85120010430: 852 The bug in 20010429 was corrected at 07:35:37 PDT. It is safe to 853 go back in the water. 854 85520010429: 856 A bad bug was committed at 04:48:42 PDT. Don't use kernels after 857 this date, but before the correction date. 858 85920010423: 860 old fsck and new kernel interactions appear to have been fixed. 861 86220010411: 863 fsck and the kernel were changed to handle some optimizations 864 to directory layout. This breaks backward compatibility. 865 Update only if you understand that you must not use the old 866 fsck with the new kernel ever. 867 86820010330: 869 fsck has changed the meaning of the pass column in /etc/fstab. 870 Please see the cvs commit to fsck.8 or the fsck.8 man page for 871 details. It is unclear if changes to /etc/fstab are necessary. 872 87320010319: 874 portmap had changed name to rpcbind for maximum POLA in your 875 current world. /etc/hosts.{allow,deny} needs changes. nfs and 876 other rpc based programs that rely on portmapper will not work 877 without updates to /etc/hosts.{allow,deny} and /etc/netconfig. 878 87920010315: 880 ata subsystem changes. ATA_ENABLE_ATAPI_DMA, ATA_ENABLE_WC 881 and ATA_ENABLE_TAGS are no longer kernel options. They have 882 been replaced by tunables. See ata.4 for details. 883 88420010312: 885 The fxp driver was converted to use miibus. If you compile 886 fxp into your kernel statically, you will need to add miibus. 887 88820010312: 889 The wi device now defaults to BSS (infrastructure) mode 890 instead of ad-hoc. 891 89220010310: 893 /dev/urandom should be a symbolic link to /dev/random now. 894 Users of current not using DEVFS need to run MAKEDEV std. 895 ssh might not work if you don't. 896 89720010303: 898 The ed driver has been updated. It now allows mii attachments, 899 which means that you must include the miibus in your kernel if 900 you use the ed driver. 901 90220010220: 903 The problems with libc have been corrected. It is now mostly 904 safe to go back into the water. 905 90620010211: 907 The size of FILE was changed. This breaks upgrading. If 908 you must upgrade, be prepared for pain. It also breaks almost 909 all binaries that you've compiled on -current. You are warned 910 that before upgrading would be a good time to do a level 0 911 dump of your system. No, really, I mean it this time. 912 913 To get to the new system, you'll need to use the following 914 workaround. Hopefully this can be sorted out so that we 915 don't have to move this to the updating section. 916 917 To get around the installworld problem, do: 918 # cd /usr/src/usr.bin/sed 919 # make install 920 # cd /usr/src 921 # make installworld 922 If that doesn't work, then try: 923 # make -k installworld 924 # make installworld 925 92620010207: 927 DEVFS is now the default. If you use vinum, make sure that you 928 do not include devfs in your kernel as problems result. 929 93020010205: 931 FFS_ROOT and CD9660_ROOT have been removed or deprecated. 932 Remove them from your config. 933 93420010122: 935 ****************************** WARNING ****************************** 936 buildkernel has been changed slightly 937 ****************************** WARNING ****************************** 938 KERNCONF replaces the variable KERNEL for buildkernel. You 939 should update your scripts and make.conf accordingly. 940 94120010119: 942 config has changed to allow DEV_FOO as a replacement for NFOO. 943 This requires a new config to build correctly. 944 94520010116: 946 The kernel option I386_CPU is now mutually exclusive with the 947 other cpu types. If you have an i386 system, be sure that it 948 only had this line. Remove it for all other configurations. 949 95020010110: 951 Changes to the kernel require it and burncd be in sync. 952 95320010102: 954 Everyone who has hw.sndunit set to something in 955 /etc/sysctl.conf, it is now hw.snd.unit. 956 95720010101: 958 ex and vi were broken by some changes to sys/queue.h. If you 959 have a bad vi, you will see make buildworld fail with a core 960 dump while building termcap. You can work around this problem 961 by adding -k to your make buildworld. This will cause the 962 build to complete and install a new vi. Once that's done, you 963 can rebuild again without the -k to pick up anything that 964 might have been ignored by the -k option. 965 966 Others have suggested that you can just rebuild libc if your 967 vi/ex is dynamically linked, but I've not received any reports 968 of this working. 969 97020001228: 971 There have been some changes to libcrypt in -current. The 972 libscrypt/libdescrypt symlink silliness is gone and the installed 973 libcrypt is fully functional. Be aware of this. 974 97520001218: 976 Linksys Fast Ethernet PCCARD cards supported by the ed driver 977 now require the addition of flag 0x80000 to their config line 978 in pccard.conf(5). This flag is not optional. These Linksys 979 cards will not be recognized without it. 980 98120001205: 982 Important new FreeBSD-version stuff: PAM support has been worked 983 in, partially from the "Unix" OpenSSH version. This requires 984 adding the following in pam.conf: 985 986 sshd auth sufficient pam_skey.so 987 sshd auth required pam_unix.so try_first_pass 988 sshd session required pam_permit.so 989 99020001031: 991 cvs updated to 1.11. 992 99320001020: 994 The random device needs more entropy, so you need to make sure 995 that you've run mergemaster to get a /etc/rc which will seed 996 /dev/random. If you don't and the system hangs after ldconfig, 997 then banging on the keyboard randomly until it unhangs is one 998 workaround. 999 100020001010: 1001 ****************************** WARNING ****************************** 1002 Sendmail has been updated. 1003 ****************************** WARNING ****************************** 1004 o mail.local(8) is no longer installed as a set-user-id binary. 1005 o sendmail(8) is now built with STARTTLS support unless NO_OPENSSL 1006 is set. 1007 o The default /etc/mail/sendmail.cf disables the SMTP EXPN and VRFY 1008 commands. 1009 o Now using sendmail's version of vacation(1). 1010 o The sendmail cf building tools (contrib/sendmail/cf) are installed 1011 in /usr/share/sendmail/cf. 1012 o sendmail.cw changed to local-host-names 1013 1014 More details can be found at 1015 http://people.freebsd.org/~imp/UPDATING/sendmail-20001010 1016 101720001009: 1018 The ports tree's new layout is in place. Be sure to update 1019 your entire ports tree, or you will have problems. 1020 102120001006: 1022 The perl build procedure no longer installs miniperl, nor uses 1023 the installed miniperl. It is recommended that you delete 1024 /usr/bin/miniperl. 1025 102620001005: 1027 This weekend the ports tree will be updated to a new layout. 1028 It will be in an inconsistent state until noted in the UPDATING 1029 file, or with asami-san's message to the relevant mailing 1030 lists. With this new layout, you'll need to update the whole 1031 tree for anything to work. 1032 103320000928: 1034 There was a change in the passwd format. Need more information. 1035 103620000916: 1037 /boot/kernel/kernel.ko -> /boot/kernel/kernel change has taken 1038 place. Please update boot loader (not the boot blocks) at the 1039 same time as your kernel. 1040 104120000914: 1042 The new pmtimer device is necessary for laptops. Failure to 1043 include the device will cause suspended laptops losing time 1044 when they resume. Include 1045 device pmtimer 1046 in your config file and 1047 hint.pmtimer.0.at="isa" 1048 to your /boot/device.hints file. 1049 105020000911: 1051 The random device has been turned into a (pseudo-)device, 1052 rather than an option. The supplied kernel config files have 1053 been updated. You will need to do something similar in your 1054 own kernel config file. 1055 Remove: 1056 options RANDOMDEV 1057 Add: 1058 device random 1059 If you prefer to load the loadable module, you need to do 1060 nothing. 1061 106220000909: 1063 The random device module has been renamed from randomdev.ko to 1064 random.ko. You will need to edit your /boot/loader.conf to 1065 reflect this if you load this module at boot time. 1066 The line should read: 1067 random_load="YES" 1068 106920000907: 1070 The SMPNG commit has happened. It should work, but if it 1071 doesn't, fallback to the PRE_SMPNG CVS tag. There are likely 1072 to be a variety of minor issues. Please see 20000905 to make 1073 sure you don't have model loading problems which might at 1074 first blush appear related to SMP. 1075 107620000906: 1077 nsswitch has been imported from NetBSD. Among other things, 1078 this means that /etc/host.conf is no longer used. See 1079 nsswitch.conf(5) instead. Note that at boot time rc.network 1080 will attempt to produce a new nsswitch.conf file for you if you 1081 don't have one, and you have host.conf. 1082 108320000905: 1084 The ucred structure changed size. This breaks the interface 1085 that mountd uses. Trying to use an older mountd with a newer 1086 kernel guarantees a panic. This means that you need to use 1087 kernels newer than today only with matching mountd, but you 1088 needed to do that anyway with the boot loader changes. 1089 109020000905: 1091 The boot loader has been updated. The new default kernel is 1092 now /boot/kernel/kernel.ko. The new default module location 1093 is /boot/kernel. 1094 1095 You *MUST* upgrade your boot loader and kernel at the same time. 1096 The easiest way to do this is to do the buildworld/buildkernel/ 1097 installkernel/installworld dance. 1098 1099 Furthermore, you are urged to delete your old /modules directory 1100 before booting the new kernel, since kldload will find stale 1101 modules in that directory instead of finding them in the correct 1102 path, /boot/kernel. The most common complaint that this cures 1103 is that the linux module crashes your machine after the update. 1104 1105 if [ ! -d /boot/kernel.old ]; then 1106 mv /modules.old /boot/kernel.old 1107 chflags noschg /kernel.old 1108 mv /kernel.old /boot/kernel.old/kernel.ko 1109 chflags schg /boot/kernel.old/kernel.ko 1110 fi 1111 111220000904: 1113 A new issue with the sendmail upgrade has come to light. 1114 /etc/aliases has moved to /etc/mail/aliases. Mergemaster will 1115 incorrectly install the default aliases in /etc/mail rather than 1116 move the old one from /etc. So you'll need to manually move the 1117 file, create a symbolic link, remove the old /etc/aliases.db and 1118 run newaliases. For safety sake, you should stop sendmail 1119 while doing this and run the upgrade when locally sourced email 1120 is not likely to be generated. 1121 112220000825: 1123 /boot/device.hints is now required for installkernel to 1124 succeed. You should copy GENERIC.hints for your architecture 1125 into /boot/device.hints. If and only if you compile hints 1126 into your kernel, then this file may be empty. Please note, 1127 if you have an empty or missing /boot/device.hints file and 1128 you neglected to compile hints into your kernel, no boot 1129 messages will appear after the boot loader tries to start the 1130 kernel. 1131 113220000821: 1133 If you do NOT have ``options RANDOMDEV'' in your kernel and 1134 you DO want the random device then add randomdev_load="YES" to 1135 /boot/loader.conf. 1136 113720000812: 1138 suidperl is now always built and installed on the system, but 1139 with permissions of 511. If you have applications that use 1140 this program, you are now required to add ENABLE_SUIDPERL=true 1141 to /etc/make.conf. If you forget to do this, 1142 chmod 4511 /usr/bin/suidperl 1143 will fix this until the next build. 1144 114520000812: 1146 sendmail has been updated from 8.9.3 to 8.11.0. Some of the more 1147 visible changes that may immediately affect your configuration 1148 include: 1149 - New default file locations from src/contrib/sendmail/cf/README 1150 - newaliases limited to root and trusted users 1151 - MSA port (587) turned on by default 1152 - New queue file naming system so can't go from 8.11 -> 8.9 1153 - FEATURE(`rbl') renamed to FEATURE(`dnsbl') 1154 - FEATURE(`nullclient') is more full featured 1155 - FEATURE(`nouucp') requires an argument: `reject' or `nospecial' 1156 - mail.local FreeBSD-only -b option changed to -B 1157 - See src/contrib/sendmail/RELEASE_NOTES for more info 1158 115920000810: 1160 suidperl (aka sperl) is no longer build by default. You must 1161 specifically define BUILD_SUIDPERL to "true" for it to be build. 1162 Furthermore, we recommend that you remove /usr/bin/sperl* and 1163 /usr/bin/suidperl files from your system unless you have a 1164 specific use for it. 1165 116620000729: 1167 Networking defaults have been tightened. Anybody upgrading 1168 /etc/defaults/rc.conf needs to add the following lines to 1169 /etc/rc.conf if they want to have the same setup 1170 afterwards (unless the variables already are set, of course): 1171 # Enable network daemons for user convenience. 1172 inetd_enable="YES" 1173 portmap_enable="YES" 1174 sendmail_enable="YES" 1175 117620000728: 1177 If you have null_load="YES" in your /boot/loader.conf, you 1178 will need to change that to nullfs_load="YES". 1179 118020000728: 1181 The "installkernel" target has changed slightly. Now even if 1182 you override KERNEL e.g. 'make installkernel KERNEL=MYKERNEL' 1183 it will install the MYKERNEL file (built with the buildkernel 1184 target) as /kernel rather than /MYKERNEL. Those who have 1185 updated their /boot/loader.conf files to point to /MYKERNEL 1186 should remove that entry or perform manual rename of /kernel 1187 to /MYKERNEL. 1188 118920000711: 1190 If you use CVSUP or CTM to get CVS trees, AND you used to get 1191 the old crypto files from internat.freebsd.org AND you check 1192 out files from the CVS tree with the cvs command, please read 1193 http://people.freebsd.org/~imp/internat.txt 1194 for details on potential problems that you might have and how 1195 to get around them. 1196 1197 If you are merely a mirror, or don't answer yes to each of the 1198 clauses above, you needn't worry. 1199 120020000711: 1201 /etc/security has been updated to print the inode number of 1202 setuid programs that have changed. You will see a large spike 1203 in the number of changed programs the first time when you run 1204 mergemaster to get a new /etc/security. 1205 120620000710: 1207 /dev/random now has good entropy collection (from the keyboard 1208 and sysmouse drivers). Please ensure that either `options 1209 RANDOMDEV' is present in your kernel config file or that 1210 `randomdev_load="YES"' is in your /boot/loader.conf. If you do 1211 not have the /dev/random driver, OpenSSL (and consequently 1212 lots of crypto tools (like SSH)) will fail with strange 1213 errors. (see below, 20000624). 1214 1215 FreeBSD-current is safe again to run Crypto. 1216 121720000709: 1218 phk made the malloc default options AJ. This may slow things 1219 down and uncover other latent bugs in the code. If you need to 1220 run at full speed, you can disable this by doing the following: 1221 ln -s aj /etc/malloc.conf 1222 122320000706: 1224 libftpio's version was accidentally bumped a few days ago. This 1225 has been corrected. You may need to remove /usr/lib/libftpio.so.6 1226 before doing your next buildworld/installworld pair. It certainly 1227 won't hurt to remove it before the update procedure. It will 1228 break fetch until a new one is built, but ftp can be used in the 1229 interim if needed. 1230 123120000705: 1232 The crypto packages have changed for the cvsup. This has been done 1233 in a backward compatible way, but the old packages will go away at 1234 some point in the future. Look at /usr/share/examples/cvsup for 1235 details. 1236 123720000704: 1238 With the new sys/modules/sound/drivers/*, you will need to 1239 set SYSDIR until you do an installworld after July 7th. 1240 124120000704: 1242 rc.shutdown and rc will now call the rc.d scripts with start 1243 or stop. This may cause some harmless warnings from older 1244 rc.d scripts that haven't been updated. 1245 124620000630: 1247 The libfetch based version of fetch has gone into the tree. 1248 Minor problems may result on some of the less popular sites, 1249 which should be reported to des@freebsd.org. 1250 125120000625: 1252 From approximately this date forward, one must have the crypto 1253 system installed in order to build the system and kernel. 1254 While not technically strictly true, one should treat it as 1255 required and grab the crypto bits. If you are grabbing CVS 1256 trees, src-all and cvs-crypto should be treated as if they 1257 were required. You should check with the latest collections 1258 to make sure that these haven't changed. 1259 126020000624: 1261 Mark Murray just committed the first parts of a cleanup of 1262 /dev/zero, et al. This is also cleaning up /dev/random. 1263 The entropy is disconnected, so DO NOT USE VERSIONS OF FREEBSD 1264 -CURRENT FROM THIS POINT to 2000710 for cryptographic services 1265 until Mark can merge in the fixes to this work in progress. 1266 openssh and openssl should not be used to generate keys from this 1267 date to the completion of the work. 1268 1269 If you must operate at this reduced level of security, add ' 1270 options RANDOMDEV' to your kernel or modload the randomdev 1271 module. You may also need to copy a new MAKEDEV to /dev and 1272 recreate the random and urandom devices. 1273 127420000622: 1275 The license on the softupdates is now a standard 2 clause 1276 BSD license. You may need to remove your symbolic links 1277 that used to be required when updating. 1278 127920000621: 1280 Scott Flatman <sf@aracnet.com> sent in a decent write-up on 1281 the config file update procedure. 1282 http://people.freebsd.org/~imp/config-upd.html 1283 NOTE: LINT is gone. It has been replaced with NOTES. NOTES 1284 isn't buildable. However, you can generate a LINT file: 1285 cd /sys/<ARCH>/conf && make LINT 1286 128720000620: 1288 Binutils 2.10 have hit the tree, or will shortly. As soon 1289 as they do, the problem noted in 20000522 will be resolved and 1290 that workaround will no longer be required. 1291 129220000615: 1293 phk removed the compatibility creation of wd devices in the 1294 ad driver. If you haven't done so already, you must update 1295 your fstab, etc to use the ad devices instead of the wd 1296 devices. 1297 1298 In addition, you'll need to update your boot blocks to a 1299 more modern version, if you haven't already done so. Modern 1300 here means 4.0 release or newer (although older releases 1301 may work). 1302 130320000612: 1304 Peter took an axe to config(8). Be sure that you read his mail 1305 on the topic before even thinking about updating. You will 1306 need to create a /boot/device.hints or add a hints directive 1307 to your config file to compile them in statically. The format 1308 of the config file has changed as well. Please see GENERIC or 1309 NEWCARD for examples of the new format. 1310 1311 Indirectly, this also breaks USERCONFIG. Unless a newer entry 1312 says that it has been fixed, assume that must use the hints mechanism 1313 in the loader if you need to use a machine with very old ISA cards 1314 in it. 1315 131620000522: 1317 A new set of binutils went into the tree today. Anybody 1318 building a kernel after this point is advised that they need 1319 to rebuild their binutils (or better yet do a 1320 buildworld/installworld) before building a new kernel. 1321 1322 Due to bugs in binutils, using malloc options (eg /etc/malloc.conf 1323 or MALLOC_OPTIONS env var) J will cause ld to dump core. It 1324 is recommended that you don't set this option until the problem 1325 is resolved. 1326 132720000513: 1328 The ethernet drivers were all updated to clean up the BPF handling. 1329 133020000510: 1331 The problems with boot blocks on the alphas have been corrected. 1332 This will require some care in updating alphas. A new libstand 1333 is requires for the boot blocks to build properly. 1334 133520000503: 1336 Recompile all kld modules. Proper version dependency info 1337 is now available. 1338 133920000502: 1340 Modules have been disconnected from the buildworld tree and 1341 connected to the kernel building instead. 1342 134320000427: 1344 You may need to build gperf 1345 cd /usr/src/gnu/usr.bin/gperf && make depend all install 1346 when upgrading from 4.0 -> current. The build system now uses 1347 an option only in -current. 1348 134920000417: 1350 The method that we brand ELF binaries has changed to be more 1351 acceptable to the binutils maintainers. You will need to 1352 rebrand your ELF binaries that aren't native. One problem 1353 binary is the Linux ldconfig. After your make world, but 1354 before you reboot, you'll need to issue: 1355 brandelf -t Linux /compat/linux/sbin/ldconfig 1356 if you have Linux compatibility enabled on your machine. 1357 135820000320: 1359 If you have really bad/marginal IDE drives, you may find they 1360 don't work well. Use pio mode instead. The easiest way to 1361 cope if you have a problem combination is to add: 1362 /sbin/sysctl hw.ata.ata_dma=0 1363 to the start of /etc/rc.conf. 1364 136520000319: 1366 The ISA and PCI compatibility shims have been connected to the 1367 options COMPAT_OLDISA and COMPAT_OLDPCI. If you are using old 1368 style PCI or ISA drivers (i.e. tx, voxware, etc.) you must 1369 include the appropriate option in your kernel config. Drivers 1370 using the shims should be updated or they won't ship with 1371 5.0-RELEASE, targeted for 2001. 1372 137320000318: 1374 We've entered the traditional post release dumping party. 1375 Large kernel changes are being committed and are in the 1376 works. It is important to keep the systems' klds and kernel 1377 in sync as kernel interfaces and structures are changing. 1378 Before reporting kernel panics, make sure that all modules 1379 that you are loading are up to date. 1380 138120000315: 1382 If you are upgrading from an older version of FreeBSD, you 1383 need to update your boot blocks as well. 'disklabel -B ad0' 1384 will do the trick. This isn't critical until you remove your 1385 wd device entries in /dev, at which point your system will not 1386 boot. 1387 138820000315: 1389 4.0 RELEASE shipped. Please see the 4.0 UPDATING file for how 1390 to upgrade to 4.0 from 3.x. 1391 1392COMMON ITEMS: 1393 1394 General Notes 1395 ------------- 1396 Avoid using make -j when upgrading. From time to time in the 1397 past there have been problems using -j with buildworld and/or 1398 installworld. This is especially true when upgrading between 1399 "distant" versions (eg one that cross a major release boundary 1400 or several minor releases, or when several months have passed 1401 on the -current branch). 1402 1403 Sometimes, obscure build problems are the result of environment 1404 poisoning. This can happen because the make utility reads its 1405 environment when searching for values for global variables. 1406 To run your build attempts in an "environmental clean room", 1407 prefix all make commands with 'env -i '. See the env(1) manual 1408 page for more details. 1409 1410 To build a kernel 1411 ----------------- 1412 If you are updating from a prior version of FreeBSD (even one just 1413 a few days old), you should follow this procedure. With a 1414 /usr/obj tree with a fresh buildworld, 1415 make -DALWAYS_CHECK_MAKE buildkernel KERNCONF=YOUR_KERNEL_HERE 1416 make -DALWAYS_CHECK_MAKE installkernel KERNCONF=YOUR_KERNEL_HERE 1417 1418 To just build a kernel when you know that it won't mess you up 1419 -------------------------------------------------------------- 1420 This assumes you are already running a 5.X system. Replace 1421 ${arch} with the architecture of your machine (e.g. "i386", 1422 "alpha", "amd64", "ia64", "pc98", "sparc64", etc). 1423 1424 cd src/sys/${arch}/conf 1425 config KERNEL_NAME_HERE 1426 cd ../compile/KERNEL_NAME_HERE 1427 make depend 1428 make 1429 make install 1430 1431 If this fails, go to the "To build a kernel" section. 1432 1433 To rebuild everything and install it on the current system. 1434 ----------------------------------------------------------- 1435 # Note: sometimes if you are running current you gotta do more than 1436 # is listed here if you are upgrading from a really old current. 1437 1438 <make sure you have good level 0 dumps> 1439 <maybe fix /etc/fstab> [7] 1440 make buildworld 1441 make buildkernel KERNCONF=YOUR_KERNEL_HERE 1442 make installkernel KERNCONF=YOUR_KERNEL_HERE 1443 [1] 1444 <reboot in single user> [3] 1445 /etc/rc.d/preseedrandom [10] 1446 mergemaster -p [5] 1447 make installworld 1448 mergemaster [4] 1449 <reboot> 1450 1451 1452 To cross-install current onto a separate partition 1453 -------------------------------------------------- 1454 # In this approach we use a separate partition to hold 1455 # current's root, 'usr', and 'var' directories. A partition 1456 # holding "/", "/usr" and "/var" should be about 2GB in 1457 # size. 1458 1459 <make sure you have good level 0 dumps> 1460 <boot into -stable> 1461 make buildworld 1462 <maybe newfs current's root partition> 1463 <mount current's root partition on directory ${CURRENT_ROOT}> 1464 make installworld DESTDIR=${CURRENT_ROOT} 1465 make buildkernel KERNCONF=YOUR_KERNEL_HERE 1466 cp /usr/src/sys/${ARCH}/conf/GENERIC.hints \ 1467 ${CURRENT_ROOT}/boot/device.hints # as needed 1468 make installkernel KERNCONF=YOUR_KERNEL_HERE DESTDIR=${CURRENT_ROOT} 1469 cd /usr/src/etc; make distribution DESTDIR=${CURRENT_ROOT} # if newfs'd 1470 cp /etc/fstab ${CURRENT_ROOT}/etc/fstab # if newfs'd 1471 <edit ${CURRENT_ROOT}/etc/fstab to mount "/" from the correct partition> 1472 <reboot into current> 1473 <do a "native" rebuild/install as described in the previous section> 1474 <maybe install compatibility libraries from /usr/src/lib/compat> 1475 <reboot> 1476 1477 1478 To upgrade in-place from 4.x-stable to current 1479 ---------------------------------------------- 1480 # 5.x uses more space than 4.x. Also, the location of kernel 1481 # modules has changed. If you are installing 5.0 onto a 4.x 1482 # system, you'll need about 30MB of free disk space on your / 1483 # partition. If you have less than this, you may encounter difficult 1484 # to back out of problems with this procedure. If /tmp is on 1485 # the / partition, you may want to completely remove all its content 1486 # before upgrading, as this can be a common source of shortage of 1487 # space on /. 1488 1489 <make sure you have good level 0 dumps> 1490 <maybe fix /etc/fstab> [7] 1491 make buildworld [9] 1492 make buildkernel KERNCONF=YOUR_KERNEL_HERE [8] 1493 cp src/sys/${MACHINE}/conf/GENERIC.hints /boot/device.hints [2] 1494 make installkernel KERNCONF=YOUR_KERNEL_HERE 1495 cd src/sys/boot ; make install [6] 1496 [1] 1497 <reboot in single user> [3] 1498 /etc/rc.d/preseedrandom [10] 1499 mergemaster -p [5] 1500 rm -rf /usr/include/g++ 1501 make installworld 1502 mergemaster [4] 1503 <reboot> 1504 1505 Make sure that you've read the UPDATING file to understand the 1506 tweaks to various things you need. At this point in the life 1507 cycle of current, things change often and you are on your own 1508 to cope. The defaults can also change, so please read ALL of 1509 the UPDATING entries. 1510 1511 Also, if you are tracking -current, you must be subscribed to 1512 freebsd-current@freebsd.org. Make sure that before you update 1513 your sources that you have read and understood all the recent 1514 messages there. If in doubt, please track -stable which has 1515 much fewer pitfalls. 1516 1517 [1] If you have third party modules, such as vmware, you 1518 should disable them at this point so they don't crash your 1519 system on reboot. 1520 1521 [2] If you have legacy ISA devices, you may need to create 1522 your own device.hints to reflect your unique hardware 1523 configuration. 1524 1525 [3] From the bootblocks, boot -s, and then do 1526 fsck -p 1527 mount -u / 1528 mount -a 1529 cd /usr/src 1530 adjkerntz -i # if CMOS is wall time 1531 Also, when doing a major release upgrade, it is required that 1532 you boot into single user mode to do the installworld. 1533 For the 4.x -> 5.0 upgrade, you will also see many messages about 1534 needing to recompile your userland. These are harmless and can 1535 be ignored while you proceed to the next step. 1536 1537 [4] Note: This step is non-optional. Failure to do this step 1538 can result in a significant reduction in the functionality of the 1539 system. Attempting to do it by hand is not recommended and those 1540 that pursue this avenue should read this file carefully, as well 1541 as the archives of freebsd-current and freebsd-hackers mailing lists 1542 for potential gotchas. 1543 1544 [5] Usually this step is a noop. However, from time to time 1545 you may need to do this if you get unknown user in the following 1546 step. It never hurts to do it all the time. You may need to 1547 install a new mergemaster (cd src/usr.sbin/mergemaster && make 1548 install) after the buildworld before this step if you last updated 1549 from current before 20020224 or from -stable before 20020408. 1550 1551 [6] 4.x boot loader can be used to boot a 5.x system, however 1552 it is difficult to do that at best. If you wish to try, then 1553 you should interrupt the boot and at the ok prompt type: 1554 ok unload 1555 ok boot /boot/kernel/kernel 1556 If this fails to work, you must install a new boot loader as 1557 described here. 1558 1559 [7] Before you upgrade, please make sure that you are not using 1560 compatibility slices. These are device names of the form, on i386 1561 and other architectures that use MBR slicing, /dev/ad0a without the 1562 actual slice name. Chances are excellent that these will break. 1563 You generally must update these entries to use the post FreeBSD 1564 2.x form of /dev/ad0s1a. 1565 1566 [8] In order to have a kernel that can run the 4.x binaries 1567 needed to do an installworld, you must include the COMPAT_FREEBSD4 1568 option in your kernel. Failure to do so may leave you with a system 1569 that is hard to boot to recover. 1570 1571 [9] When checking out sources, you must include the -P flag to have 1572 cvs prune empty directories. 1573 1574 [10] In order to create temporary files, /dev/random must be 1575 initialized by feeding data into it. /etc/rc.d/preseedrandom 1576 takes care of this. 1577FORMAT: 1578 1579This file contains a list, in reverse chronological order, of major 1580breakages in tracking -current. Not all things will be listed here, 1581and it only starts on March 15, 2000. Updating files can found in 1582previous releases if your system is older than this. 1583 1584Copyright information: 1585 1586Copyright 1998, 2002 M. Warner Losh.
