UPDATING revision 130921
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 2020040621: 21 On 20040524, the /etc/rc.d/nsswitch script was modified to 22 automatically create /etc/nsswitch.conf on startup if it did 23 not already exist. Unfortunately, an error in the man page 24 was carried over to the script, resulting in incorrect 25 nsswitch settings. The simplest remedy is to remove both 26 /etc/nsswitch.conf and /etc/host.conf; they will be recreated 27 during the next reboot. 28 2920040614: 30 The return value of sema_timedwait(9) has been changed to 31 make it consistent with cv_timedwait(9). Be sure to recompile 32 the ips module and any third-party modules which call 33 sema_timedwait. 34 3520040613: 36 ALTQ is now linked to the build. This breaks ABI for struct ifnet. 37 Make sure to recompile modules and any userland that makes use of 38 sizeof(struct ifnet). In order to get the altq headers in place 39 please recompile and reinstall world. 40 4120040607: 42 Splitting kern_thread.c into 2 files (adding kern_kse.c) 43 requires that you re-run config after updating your tree. 44 4520040601: 46 The MIDI drivers have been removed. Until the new module-friendly 47 ones are merged, remove or comment out midi and seq from your 48 kernel configuration. 49 5020040423: 51 Due to a new option in ipfw (versrcreach) the ipfw(8) command 52 needs to be recompiled. Normal accept/reject rules without 53 options are not affected but those with options may break until 54 ipfw(8) is recompiled. 55 5620040420: 57 Due to changes in the callout ABI, kernels compiled after this 58 date may be incompatible with kernel modules compiled prior to 59 20040406. 60 6120040414: 62 The PCI bus power state stuff has been turned on. If this causes 63 problems for your system, please disable it using the tunable 64 hw.pci.do_powerstate=0. 65 6620040412: 67 The bulk of the pci problems have been fixed, although the floppy 68 drive is still broken. 69 7020040410: 71 A substantial update to the pci bus resource and power management 72 have been committed. Expect a bumpy ride for a few days until 73 the unanticipated problems have been resolved. 74 7520040409: 76 Due to changes in the the Yarrow initialization process, 77 /dev/random needs to be fed before operations requiring 78 temp files can succeed in single user mode. This includes 79 running "make installworld". /dev/random may be fed by running 80 "/etc/rc.d/initrandom start" or with 20040415 source by running 81 "/etc/rc.d/preseedrandom". 82 8320040322: 84 The debug.mpsafenet tunable controls whether the kernel Giant 85 lock is held across the lower levels of the network stack, and 86 by default is turned off. In the few days following 20040322, 87 the behavior of debug.mpsafenet will change such that this 88 tunable controls Giant over all levels of the network stack. 89 If you are currently setting debug.mpsafenet to 1, you should 90 set it back to 0 (the default) again during the change-over. 91 An additional note will be added to UPDATING when sufficient 92 locking is merged to permit this to take place. 93 9420040310: 95 The FreeBSD/sparc64 platform is changing time_t from 32-bits to 96 64-bits. This is a very major incompatible change, so people 97 using FreeBSD/sparc64 *must* read the UPDATING.64BTT file for 98 detailed instructions on how to make this upgrade. People 99 upgrading FreeBSD on other platforms can ignore this event. 100 10120040308: 102 The packet filter (pf) is now installed with the base system. Make 103 sure to run mergemaster -p before installworld to create required 104 user account ("proxy"). If you do not want to build pf with your 105 system you can use the NO_PF knob in make.conf. 106 Also note that pf requires "options PFIL_HOOKS" in the kernel. The 107 pf system consists of the following three devices: 108 device pf # required 109 device pflog # optional 110 device pfsync # optional 111 11220040303: 113 If you are having trouble with the libc_r -> libpthread transition 114 (see the 20040130 entry), place the following lines at the top of 115 /etc/libmap.conf: 116 117 libc_r.so.5 libpthread.so.1 118 libc_r.so libpthread.so 119 120 This will cause all programs and libraries linked against libc_r 121 to use libpthread instead. 122 12320040226: 124 Some sshd configuration defaults have changed: protocol version 1 125 is no longer enabled by default, and password authentication is 126 disabled by default if PAM is enabled (which it is by default). 127 OpenSSH clients should not be affected by this; other clients may 128 have to be reconfigured, upgraded or replaced. 129 13020040225: 131 The ABIs defined in <resolv.h> and <netdb.h> have been updated 132 to support improved reentrancy. Multi-threaded programs that 133 reference the "_res" or "h_errno" symbols may experience some 134 problems if they are not recompiled. Single-threaded programs 135 should remain unaffected. 136 13720040225: 138 routed has been updated in the base system from the vendor 139 sources, routed v2.27, from rhyolite.com. This change means that 140 for users who use RIP's MD5 authentication feature, FreeBSD 141 -CURRENT's routed is now incompatible with previous versions 142 of FreeBSD; however it is now compatible with implementations 143 from Sun, Cisco and other vendors. 144 14520040224: 146 The tcpcb structure has changed and makes a recompile of libkvm 147 and related userland network utilities neccessary. 148 14920040222: 150 The cdevsw structure has changed in two externally visible ways. 151 First, the sense of the D_GIANT flag has changed to D_NEEDSGIANT. 152 Second, the d_version field must be filled in with D_VERSION. 153 Drivers outside the tree will need to be updated. 154 15520040207: 156 The /etc/rc.d/ttys script has been removed. It is no longer 157 necessary since devfs has been mandatory for some time. 158 15920040130: 160 libkse has been renamed back to libpthread and is now the 161 default threads library. The gcc -pthread option has also 162 been changed to link to libpthread instead of libc_r. For 163 alpha and sparc64 machines, libkse is not renamed and links 164 are installed so that libpthread points to libc_r. Until 165 the ports system is updated to handle this change, it is 166 recommended that folks install an /etc/libmap.conf(5) that 167 maps libc_r to libpthread. If you have any binaries or 168 libraries linked to libkse, then it is also recommended 169 that you map libkse to libpthread. Anyone that is using 170 nvidia supplied drivers and libraries should use a libmap.conf 171 that maps libpthread to libc_r since their drivers/libraries 172 do not work with libpthread. 173 17420040125: 175 ULE has entered into its probationary period as the default scheduler 176 in GENERIC. For the average user, interactivity is reported to be 177 better in many cases. On SMP machines ULE will be able to make more 178 efficient use of the available parallel resources. If you are not 179 running it now, please switch over, replacing the kernel option 180 SCHED_4BSD with SCHED_ULE. 181 18220040125: 183 Move LongRun support out of identcpu.c, where it hardly 184 belongs, into its own file and make it opt-in, not mandatory, 185 depending on CPU_ENABLE_LONGRUN config(8) option. 186 18720031213: 188 src/lib/libc/gen/initgroups.c:1.8 now causes logins to fail 189 if the login process is unable to successfully set the 190 process credentials to include all groups defined for the 191 user. The current kernel limit is 16 groups; administrators 192 may wish to check that users do not have over 16 groups 193 defined, or they will be unable to log in. 194 19520031203: 196 The ACPI module has been reactivated. It is no longer required 197 to compile ACPI support into kernels statically. 198 19920031112: 200 The statfs structure has been updated with 64-bit fields to 201 allow accurate reporting of multi-terabyte filesystem 202 sizes. You should build world, then build and boot the new kernel 203 BEFORE doing a `installworld' as the new kernel will know about 204 binaries using the old statfs structure, but an old kernel will 205 not know about the new system calls that support the new statfs 206 structure. 207 Note that the backwards compatibility is only present when the 208 kernel is configured with the COMPAT_FREEBSD4 option. Since 209 even /bin/sh will not run with a new kernel without said option 210 you're pretty much dead in the water without it. Make sure you 211 have COMPAT_FREEBSD4! 212 Running an old kernel after a `make world' will cause programs 213 such as `df' that do a statfs system call to fail with a bad 214 system call. Marco Wertejuk <wertejuk@mwcis.com> also reports 215 that cfsd (ports/security/cfs) needs to be recompiled after 216 these changes are installed. 217 218 ****************************DANGER******************************* 219 220 DO NOT make installworld after the buildworld w/o building and 221 installing a new kernel FIRST. You will be unable to build a 222 new kernel otherwise on a system with new binaries and an old 223 kernel. 224 22520031112: 226 Some netgraph string length constants have been changed. This 227 change requires the netgraph kernel modules and all netgraph 228 userland components to be in sync. Especially users who require 229 netgraph to boot need to make sure to have world and kernel in 230 sync before rebooting. 231 23220031111: 233 Hyperthreading logical CPU's are no longer probed by default 234 when using the MP Table. If ACPI is being used, then logical 235 CPUs will be probed if hyperthreading is enabled in the BIOS. 236 If ACPI is not being used and hyperthreading is enabled in the 237 BIOS, logical CPUs can be enabled by building a custom kernel 238 with the option MPTABLE_FORCE_HTT enabled. 239 24020031103: 241 The i386 APIC_IO kernel option has been replaced by 242 'device apic'. The ACPI module has also been temporarily 243 disabled, so ACPI must be statically compiled into your 244 kernel using 'device acpi' if you wish to use the ACPI driver. 245 24620031031: 247 The API and ABI of struct ifnet have been changed by removing 248 the if_name and if_unit members and replacing them with 249 if_xname, if_dname, and if_dunit. All network drivers and most 250 userland programs which include net/if_var.h must be updated 251 and recompiled. __FreeBSD_version has been bumped to 501113 to 252 reflect this change. 253 25420030928: 255 Changes to the cdevsw default functions have been made to remove 256 the need to specify nullopen() and nullclose() explicitly. 257 __FreeBSD_version bumpted to 501110. 258 25920030926: 260 kiconv(3) has been added. mount_msdosfs(8), mount_ntfs(8) and 261 mount_cd9660(8) need to be in sync with kernel. 262 26320030925: 264 Configuring a system to use IPFILTER now requires that PFIL_HOOKS 265 also be explicitly configured. Previously this dependency was 266 magically handled through some cruft in net/pfil.h; but that has 267 been removed. Building a kernel with IPFILTER but not PFIL_HOOKS 268 will fail with obtuse errors in ip_fil.c. 269 27020030923: 271 Fix a bug in arplookup(), whereby a hostile party on a locally 272 attached network could exhaust kernel memory, and cause a system 273 panic, by sending a flood of spoofed ARP requests. See 274 FreeBSD-SA-03:14.arp. 275 27620030915: 277 A change to /etc/defaults/rc.conf now causes inetd to be started 278 with `-C 60' if it is not overridden in /etc/rc.conf. This 279 causes inetd to stop accepting connections from an IP address 280 that exceeds the rate of 60 connections per minute. 281 28220030829: 283 The following rc.d scripts have been removed and should be 284 deleted from your installation: atm2.sh atm3.sh devdb 285 localdaemons network1 network2 network3. Depending on when 286 you last updated world and used mergemaster(8) you may or 287 may not have problems during the rc boot sequence. The simplest 288 solution is an 'rm -rf /etc/rc.d/*' and then 'mergemaster -i'. 289 The atm2.sh atm3.sh and devdb scripts were removed some time 290 ago, so depending on when you installed -CURRENT these scripts 291 may or may not exist on your system. 292 29320030824: 294 ATAng has been committed. You need to build world as sys/ata.h 295 has changed, and userland atacontrol depends on it. 296 If you use ATA SW raids you need "device ataraid" in your 297 kernel config file, as it is no longer pulled in automatically. 298 29920030819: 300 The OFW_NEWPCI option has been turned on in the Sparc64 GENERIC kernel. 301 Among other things, this changes the device enumeration to be 302 closer to Solaris. Be aware that, this can even cause the machine 303 to not boot without manual intervention before the fstab is adjusted. 304 30520030728: 306 All current USB and Firewire quirks in da(4) have been deprecated 307 and will be removed for 5.2. If this causes failure for your 308 umass(4) devices, enable "options DA_OLD_QUIRKS" in your kernel 309 and send the output of "camcontrol inquiry da0" to scsi@freebsd.org 310 so the quirk can be re-enabled. 311 31220030724: 313 Problems with entry 20030714 have been corrected and no known issues 314 with /rescue and -j exist for host systems after this point in time. 315 31620030722: 317 FPU-less support has been removed from FreeBSD. Chances are you won't 318 notice. 386+387 support should still work after this change, but 319 it is now a minimum requirement for the i386 port that you have real 320 FPU hardware. 321 32220030714: 323 Some people are having problems with changes related to /rescue. 324 If you are building -j N, you will need to define NO_RESCUE. Others 325 will need to define it if /rescue has issues with their environment. 326 People should report those issues to current@. 327 32820030711: 329 gcc was upgraded to 3.3. You are advised to not build -DNOCLEAN 330 across this point. Further, it might be a good idea to remove 331 /usr/obj. 332 33320030610: 334 Remove deprecated locale names and transition period code 335 for them, finishing switching to the new scheme. Check your 336 LANG environment variable. 337 33820030609: 339 CCD has been changed to be a fully GEOMified class. Kernel 340 and ccdconfig(8) needs to be in sync, this is particularly 341 important to remember beforehand if your source tree is on 342 a ccd device. Consider making a copy of the old ccdconfig 343 into /boot/kernel.good or wherever you keep your backup 344 kernel. 345 34620030605: 347 There was a small window in which sed(1) was broken. If you 348 happen to have sed(1) installed during that window, which is 349 evidenced by an inability to build world with the failure 350 given below, you need to manually build and install sed(1) 351 (and only sed(1)) before doing anything else. This is a one- 352 time snafu. Typical failure mode: 353 354 In file included from /usr/src/contrib/binutils/bfd/targets.c:1092: 355 targmatch.h:7:1: null character(s) ignored 356 targmatch.h:12:1: null character(s) ignored 357 targmatch.h:16:1: null character(s) ignored 358 : 359 360 The window of "sed(1)-uction" is from Wed Jun 4 15:31:55 2003 UTC 361 to Thu Jun 5 12:10:19 2003 UTC (from rev 1.30 to rev 1.31 of 362 usr.bin/sed/process.c). 363 36420030505: 365 Kerberos 5 (Heimdal) is now built by default. Setting 366 MAKE_KERBEROS5 no longer has any effect. If you do NOT 367 want the "base" Kerberos 5, you need to set NO_KERBEROS. 368 36920030502: 370 groff has been updated. If you try to do a buildworld and 371 get an infinite loop in troff, update to May 4th or newer. If you 372 have a newer kernel than userland, you may need to set the OSRELDATE 373 to 500110 in your environment before starting a buildworld. 374 37520030501: 376 The old rc system has been removed. Please report any problems 377 to freebsd-rc@yahoogroups.com, and/or freebsd-current@freebsd.org. 378 Your personal versions of these files will not be removed, so you can 379 continue to use them. However, you should take great care when updating, 380 especially when using mergemaster, since the compatibility code that 381 utilizes these old scripts has also been removed. 382 38320030423: 384 A bug has been fixed in /dev/devctl which would cause devd 385 to hang on boot, were it not for a workaround in devd. The 386 work around in devd will be removed around 20030507. You 387 have until then to upgrade your kernel before updating 388 userland. In general, you should have a userland and 389 kernel that's in sync with each other. However, given the 390 effects of this bug (hang on boot when starting devd), some 391 allowances are made. 392 39320030329: 394 Alphas with libc from between 20030312 and 20030329 exhibit 395 floating point exceptions (FPEs), most notably in awk(1) 396 while upgrading the system through a buildworld. 397 398 So, to successfully upgrade your Alpha, you must either 399 downgrade your libc.so to a pre-20030312 version, or update 400 /usr/share/mk/bsd.cpu.mk to revision 1.26 which adds -mieee 401 to CFLAGS, then forcibly rebuild and install libc: 402 403 cd /usr/src/lib/libc && \ 404 make cleandir && make obj && \ 405 make -DNOMAN -DNOPROFILE all && \ 406 make -DNOMAN -DNOPROFILE install 407 40820030208: 409 sendmail 8.12.7 has been imported. It has one important 410 change for IPv6 users. The default submit.mc now uses 411 '[127.0.0.1]' instead of 'localhost' meaning only IPv4 is 412 used to connect to the MTA. Users on IPv6-only machines 413 will need to edit /etc/mail/submit.mc appropriately. 414 41520030128: 416 NODEVFS option has been removed and DEVFS thereby made standard. 417 This makes all references to MAKEDEV obsolete, and they should 418 be removed when convenient. 419 42020030126: 421 The name of the device for the ofw console has changed, sparc64 users 422 must run mergemaster to update their installed /etc/ttys. 423 42420030125: 425 The scheduler framework has grown a second scheduler and consequently 426 you must specify one and only one scheduler in your kernel config. 427 The cvs config files have been updated to use the old scheduler 428 which may be selected via 'options SCHED_4BSD'. If you would like 429 to try the new, much more experimental, scheduler please try 430 'options SCHED_ULE' and contribute to the arch@ discussion. 431 43220030115: 433 A new version of the wi driver has been imported into the tree. 434 One now must have device wlan in the config file for it to operate 435 properly. 436 437 In addition, there have been some changes to how wi devices are 438 configured for point to point links to bring it more in line 439 with the former way of doing things, as well as compatibility 440 with NetBSD. 441 44220021222: 443 For a period after the GCC 3.2.1 import (from 12/04 to 12/22), GCC 444 used an incompatible form of ABI for returning structures and unions 445 which FreeBSD's GCC maintainers were not aware of relative to previous 446 versions of FreeBSD. We have gone back to the ABI for now, and any 447 code compiled which is required to interoperate with other code (not 448 built at the same time) returning structs or unions should be 449 rebuilt. 450 45120021216: 452 A name change in /etc/netconfig has been reverted to stay 453 compatible with suns TIRPC and also with NetBSD. You need 454 to run mergemaster after make world. A new libc does still work 455 with an outdated /etc/netconfig for some time, but you'll get 456 a warning. This warning will be removed in 20030301. 457 45820021202: 459 The recent binutils upgrade marks a kernel flag day on 460 sparc64: modules built with the old binutils will not work 461 with new kernels and vice versa. Mismatches will result in 462 panics. Make sure your kernel and modules are in sync. 463 46420021029: 465 The value of IPPROTO_DIVERT has changed. Make sure to keep 466 your kernel, netstat, natd and any third-party DIVERT 467 consumers in sync. 468 46920021024: 470 Old, compatibility slices have been removed in GEOM kernels. 471 This means that you will have to update your /etc/fstab to 472 not use disk devices of the form /dev/ad0a. Instead, you 473 now must specify /dev/ad0s1a, or whatever slice your FreeBSD 474 partition really is on. The old device names have gone 475 away, so if you use them anywhere else, you must also adjust 476 those uses. (This doesn't affect the disks formatted in 477 the ``dangerously-dedicated'' mode.) 478 47920021023: 480 Alphas with kernels from between 20020830 and 20021023 and/or 481 rtld (ld-elf.so.1) older than 20021023 may experience problems 482 with groff while doing a buildworld (kernel: "out of memory", 483 fixed in rev 1.129 of kern/imgact_elf.c; rtld: "too few PT_LOAD 484 segments", fixed in rev 1.8 of libexec/rtld-elf/map_object.c). 485 486 So, to successfully upgrade your Alpha, you must either 487 upgrade your kernel and rtld first (which might be a bit 488 tricky), or avoid running the bootstrapped groff during the 489 "transitional" buildworld. To avoid running groff during the 490 transitional upgrade run make buildworld with -DNOMAN, 491 -DNO_SHAREDOCS, and -DNO_LPR. 492 49320020831: 494 gcc has been upgraded to 3.2. It is not all binary compatible 495 with earlier versions of gcc for c++ programs. All c++ 496 programs and libraries need to be recompiled. 497 498 Also, if you encounter g++ issues, rm /usr/include/g++/* before 499 doing an installworld to make sure that stale files are removed. 500 50120020827: 502 Our /etc/termcap now has all the entries from the XFree86 xterm 503 almost unchanged. This means xterm now supports color by default. 504 If you used TERM=xterm-color in the past you now should use 505 TERM=xterm. (xterm-color will lead to benign warnings). 506 50720020815: 508 A "bug" in gcc(1) that was hiding warning in system headers was 509 fixed. It's probably time to add -DNO_WERROR to your make line 510 again. 511 51220020729: 513 COPY is being deprecated. The 20010530 change was reverted, as 514 it causes far more pain than was expected, and to always compare 515 before installing, please use INSTALL="install -C" again. The 516 -C option is now silently ignored when used with the -d option. 517 51820020702: 519 Problems with libc_r clients like KDE and GNOME have been resolved. 520 There are still some minor problems with some signals but the 521 system is stable enough for general use again. SMP is less so than UP 522 but each can successfully complete multiple buildworlds. 523 Libkvm needs to be recompiled due to KSE. 524 52520020701: 526 Now would be a bad time to upgrade. Something in or near the 527 KSE commit totally broke programs using libc_r like KDE and 528 GNOME. 529 53020020511: 531 The k5su utility installed as part of Kerberos 5 is no longer 532 installed with the set-user-ID bit set by default. Add 533 ENABLE_SUID_K5SU=yes to /etc/make.conf to have it installed 534 with the set-user-ID bit set. 535 53620020510: 537 Gcc 3.1 debugging format (cc -g) has changed from STABS to DWARF2. 538 Unfortunately our native GDB (at version 4.18) does not understand 539 the DWARF2 debugging format. Thus you must use `gcc -gstabs+' to 540 generated debugging information for our native GDB. 541 54220020510: 543 Due to the way CVS works, it may not properly update src/contrib/gcc 544 to the 3.1 sources. The easiest fix is to `rm -rf' src/contrib/gcc 545 and then do a cvs update. 546 54720020421: 548 When exec'ing set[ug]id executables, the kernel now ensures that the 549 stdio file descriptors (0..2) are open. See FreeBSD-SA-02:23.stdio. 550 55120020404: 552 New sendmail startup scripts have been installed to make it 553 easier to use alternative MTAs with FreeBSD. Setting the rc.conf 554 variable sendmail_enable to "NO" no longer prevents any sendmail 555 daemons from starting. Instead, either set sendmail_enable to 556 "NONE" or change mta_start_script to a script for starting 557 an alternative MTA. Setting mta_start_script to "" will 558 also prevent any MTA from being started at boot. 559 56020020403: 561 UCONSOLE is no longer a valid kernel option. 562 56320020315: 564 FreeBSD 5.0 DP-1 was basically branched today. 565 56620020225: 567 Warnings are now errors in the kernel. Unless you are a developer, 568 you should add -DNO_WERROR to your make line. 569 57020020217: 571 sendmail 8.12.2 has been imported. The sendmail binary is no 572 longer a set-user-ID root binary and the infrastructure to support 573 command line mail submission has changed. Be sure to run 574 mergemaster (especially for updating /etc/rc, /etc/defaults/rc.conf, 575 and /etc/mail) and read /etc/mail/README for more details. 576 577 Due to the import of sendmail 8.12.2, a new user and group are 578 required in order for sendmail to run as a set-group-ID 579 binary. A 'make installworld' will use the new user and group 580 to set the owner and group of /var/spool/clientmqueue and will 581 fail if the new user and group do not exist. The 'smmsp' user 582 and group must be merged from src/etc/group and 583 src/etc/master.passwd before using 'make installworld'. 584 'mergemaster -p' will do this. You may need to install 585 mergemaster before this will work if you are updating from a 586 very old version of current. The updating recipe has changed 587 as of this date. 588 58920020112: 590 The preferred configuration method for PAM is now /etc/pam.d/ 591 rather than /etc/pam.conf. If you have an unmodified 592 pam.conf, just delete it after your next mergemaster run. If 593 you have local modifications, you can use 594 /usr/src/etc/pam.d/convert.pl to incorporate them into your 595 /etc/pam.d. 596 597 Please see the following url for more details: 598http://www.freebsd.org/cgi/mid.cgi?db=mid&id=<xzp6667fyoa.fsf@flood.ping.uio.no> 59920011229: 600 If anyone here is already using the new rc.conf(5) variable 601 networkfs_types, please note that it has changed 602http://www.freebsd.org/cgi/mid.cgi?db=mid&id=<9744.1009655556@axl.seasidesoftware.co.za> 603 60420011220: 605 sys/i4b/driver/i4b_ispppsubr.c has been retired. This file 606 started out its life in the ISDN4BSD project as an offspring 607 from sys/net/if_spppsubr.c, which eventually got a life of its 608 own. All the accumulated features and bugfixes of the i4b 609 version have now been merged back into the base system's 610 version now. The only user-visible change resulting from this 611 is that i4b's sppp(4) interfaces are to be managed with 612 spppcontrol(8) again, since ispppcontrol(8) has been retired 613 as well. (There has never been rc file support for 614 ispppcontrol in -current, but only in -stable. That will be 615 reverted by the time the changes are MFCed.) 616 61720011215: 618 The fdc(4) driver has been updated and now automatically 619 recognizes media in `standard' formats (like 1440 KB and 620 720 KB for a 3.5" high-density drive) when accessing the 621 default device node (e. g. /dev/fd0). The old variety of 622 floppy device nodes /dev/fd*.* is no longer present by 623 default, devices can be created (in DEVFS) on demand. They 624 will need to be customized then for `odd' densities using 625 fdcontrol(8). 626 62720011209: 628 The bugs in procfs' debugging support code have been fixed, 629 and truss(1) now works again. 630 63120011207: 632 Daily security checks have been split out to use the periodic(8) 633 scripts. Some change in configuration may be necessary. Please 634 see 635http://www.freebsd.org/cgi/mid.cgi?db=mid&id=<20011207155805.R8975@blossom.cjclark.org> 636 for details. 637 63820011204: 639 sos added VCD/SVCD support to ata driver and that needs the 640 kernel and burncd to be in sync. 641 64220011203: 643 The procfs pseudo-filesystem has now been converted to use the 644 pseudofs framework. If you have 'options PROCFS' in your 645 kernel config, you'll need to add 'options PSEUDOFS' if it's 646 not there already. 647 648 This change temporarily breaks truss(1); use ktrace(1) instead 649 until the issue has been resolved. 650 65120011202: 652 A security hole in OpenSSH involving `UseLogin yes' has been 653 patched. 654 65520011126: 656 You need to remove /usr/obj/.../usr.bin/tip before rebuilding 657 after this date. You need to do this only once. 658 65920011103: 660 Most of the awk issues have been resolved. Some rough 661 edges may be left, but for the most part things should be 662 back to "normal." For CURRENT's usual definition of "normal." 663 66420011030: 665 Awk has been upgraded to the one true awk from bell labs. Expect 666 choppy waves in the upgrade process. 667 66820011030: 669 The asr driver problem has been resolved. 670 67120011027: 672 Due to changes in other parts of the system, the asr driver 673 now causes the system to panic on boot. Do not use it pending 674 correction. Comment it out of any kernel config file that you 675 try to use from this date forward. 676 67720011025: 678 When crossbuilding, use TARGET=xxx where you used to use 679 MACHINE=xxx. You don't need to set TARGET_ARCH and TARGET, 680 unless you are changing both of them. To cross build pc98 on 681 an alpha, for example, you need to set TARGET=pc98 and 682 TARGET_ARCH=i386. 683 68420011001: 685 The kernel interface that burncd depends on has changed. 686 You must recompile both the kernel and userland applications 687 at the same time. 688 68920010929: 690 When crossbuilding, please set TARGET_ARCH rather than 691 MACHINE_ARCH to indicate the target. In the future, one will 692 set TARGET_MACHINE where you set MACHINE now. At the moment, 693 setting MACHINE alone for same MACHINE_ARCH machines works 694 (eg, you can build pc98 on an i386 machine and vice versa). 695 69620010927: 697 Some weird problems result from using ACPI on some machines. 698 To disable ACPI you can add 699 hint.acpi.0.disabled="1" 700 to /boot/loader.conf (or by putting set X=Y at the boot 701 loader "ok" prompt). 702 703 Alternatively, you can remove it from /boot/kernel/acpi.ko 704 or use the MODULES_OVERRIDE function in your kernel config 705 file and not list acpi in that list. 706 70720010924: 708 The buildworld has been fixed. You may need to install 709 the 4.x compatibility libraries for some old binaries 710 to work. Add COMPAT4X=true to your /etc/make.conf to 711 get them installed on every installworld, or execute the 712 following to get them installed only once: 713 cd src/lib/compat/compat4x.<arch> 714 make all install 715 You will see ``__stdoutp undefined'' until you do this. 716 71720010919: 718 There's a bug in the world build process. The cross-tools 719 are build with the NEW headers, but the OLD libc.a. This 720 leads to all kinds of problems with the new libc. A temporary 721 workaround is to add 722 CFLAGS="-O -pipe -D_OLD_STDIO" 723 before building world when upgrading from 4.x to current. This 724 can be removed afterwards. 725 726 A proper fix to the buildworld target is needed. 727 72820010918: 729 Peter has committed his new kthread nfs client/server code. 730 NFS may be unstable after this date. 731 73220010912: 733 KSE has hit the tree. Lots of things are now different in 734 the kernel. While a few problems were introduced in the 735 initial commit, most of the major ones have been found and 736 corrected. 737 73820010901: 739 In OLDCARD, CardBus bridges appear to be stable. The work 740 arounds described in the 20010604 entry are now no longer 741 necessary and will be ignored. Most insert/remove problems 742 have been rectified around this date. 743 74420010823: 745 named now runs as user bind and group bind rather than as 746 root. If named_enable is set to YES in /etc/rc.conf, ensure 747 that user bind is available in /etc/passwd (using vipw(8)) 748 and that group bind is available in /etc/group. Also make 749 sure that user or group bind has read (and not write) 750 permission for your name server configuration and that it 751 has read and write permission for your slave zone files and 752 directory. 753 754 If you wish to continue to run named as root (a less secure 755 alternative), add a line to /etc/rc.conf saying 756 757 named_flags= 758 75920010709: 760 The PAM libraries have had an API upgrade that is beyond 761 the ability of the shared library major number to handle. 762 It is manifested by PAM-using ports dumping core. The 763 solution is to rebuild those ports. 764 76520010628: 766 The kernel compile module has moved from src/sys/compile/FOO 767 to src/sys/${MACHINE}/compile/FOO. 768 76920010625: 770 The pccard modem issue from 20010613 has been corrected. 771 OLDCARD support is still a little weak in -current. slot 1 is 772 known not to work on some TI based cardbus bridges. Some 773 cardbus bridges do not properly detect insert/removal events. 774 IRQ configuration needs more safety belts. 775 77620010617: 777 Softupdates problems have been corrected. 778 77920010614: 780 Peter ripped out the linkerset support. You must, as always, 781 rerun config after you cvsup if you are using the traditional 782 kernel building methods. 783 78420010613: 785 pccard modems may not work with current after 20010604 date. Some 786 do, others result in panics. *MAKE*SURE* that you update your 787 config and /etc/rc.conf ala the 20010604 entry, or you will have 788 problems (this issue will be fixed, it just hasn't been yet). 789 79020010613: 791 SOFTUPDATES seem to be broken since the middle of May or so. Do not 792 use them in current. You can disable softupdates on all mounted 793 partitions, or remove SOFTUPDATES the kernel config file. 794 79520010612: 796 After Peter's commits to the hints code, people have been noticing 797 that certain devices are attached (or try to) twice. This is due 798 to having both static hints as well as a /boot/device.hints. To 799 work around this issue, please use only one or the other mechanism 800 until this bug is fixed. 801 802 Please note that a feature of config is that if you have config 803 file FOO and FOO.hints, it automatically adds FOO.hints to the 804 hints.c file, whether you want it to or not. 805 80620010610: 807 Locale names have changed to match other systems better. 808 80920010604: 810 pccard support for pci cards has been committed. You must change 811 your /etc/pccard.conf irq lines. It must match the irq used by 812 pcic device. Interrupt storms may result if you fail to do this. 813 Interrupt storms look a lot like a hang. 814 815 You must also install a new pccardd, otherwise you will get an 816 interrupt storm at card reset time (just after it tells you what 817 it is). 818 819 pccardd_flags="-I" is necessary for the time being. It tells pccardd 820 not to ask the kernel if the interrupt is really free or not before 821 using it. You can either change the /etc/pccard.conf irq lines to 822 match pcic, or add "-i X" to the pccardd_flags. 823 82420010530: 825 INSTALL=install -C is being deprecated. If you want to do this, 826 use COPY=-C instead. The former method will be supported for only 827 a limited time. If you see 828 829install: warning: the -d and -C options may not be specified together 830 831 in your makeworld, then you need to migrate towards using 832 COPY=-C. 833 83420010525: 835 It appears that vm is now stable enough to use again. However, 836 there may be other problems, so caution is still urged. alpha 837 definitely is in bad shape. 838 83920010521: 840 Minor repo damage has happened. This may cause problems 841 with cvsup of ports. If you get errors, please see 842 http://www.FreeBSD.org/cgi/query-pr.cgi?pr=27495 843 at the bottom for details on a workaround. The error message 844 is 845Updater failed: Cannot delete "/usr/ports/www/jakarta-tomcat/files": Directory not empty 846 84720010520: 848 Vm and/or swapping are busted on -current. Please be patient. 849 85020010519: 851 pccard has had much reorganizational work done to it over 852 the past few days. Everything should still work, but if 853 not, please contact imp@freebsd.org. 854 85520010517: 856 ata ioctl changed. Make sure to recompile both kernel and 857 userland at the same time. 858 85920010517: 860 New ncurses imported. 861 86220010512: 863 DEVFS is now opt out, not opt in. Barring major problems, this 864 will be the only way to go starting July 1. 865 86620010504: 867 OpenSSH has been updated to 2.9. Some defaults are different, 868 including RhostsRSAAuthentication, which changes from yes to no. 869 87020010502: 871 Perl breakage in 20010501 was corrected at 14:18:33 PDT. 872 87320010501: 874 Building perl was broken at 02:25:25 PDT. 875 87620010430: 877 The bug in 20010429 was corrected at 07:35:37 PDT. It is safe to 878 go back in the water. 879 88020010429: 881 A bad bug was committed at 04:48:42 PDT. Don't use kernels after 882 this date, but before the correction date. 883 88420010423: 885 old fsck and new kernel interactions appear to have been fixed. 886 88720010411: 888 fsck and the kernel were changed to handle some optimizations 889 to directory layout. This breaks backward compatibility. 890 Update only if you understand that you must not use the old 891 fsck with the new kernel ever. 892 89320010330: 894 fsck has changed the meaning of the pass column in /etc/fstab. 895 Please see the cvs commit to fsck.8 or the fsck.8 man page for 896 details. It is unclear if changes to /etc/fstab are necessary. 897 89820010319: 899 portmap had changed name to rpcbind for maximum POLA in your 900 current world. /etc/hosts.{allow,deny} needs changes. nfs and 901 other rpc based programs that rely on portmapper will not work 902 without updates to /etc/hosts.{allow,deny} and /etc/netconfig. 903 90420010315: 905 ata subsystem changes. ATA_ENABLE_ATAPI_DMA, ATA_ENABLE_WC 906 and ATA_ENABLE_TAGS are no longer kernel options. They have 907 been replaced by tunables. See ata.4 for details. 908 90920010312: 910 The fxp driver was converted to use miibus. If you compile 911 fxp into your kernel statically, you will need to add miibus. 912 91320010312: 914 The wi device now defaults to BSS (infrastructure) mode 915 instead of ad-hoc. 916 91720010310: 918 /dev/urandom should be a symbolic link to /dev/random now. 919 Users of current not using DEVFS need to run MAKEDEV std. 920 ssh might not work if you don't. 921 92220010303: 923 The ed driver has been updated. It now allows mii attachments, 924 which means that you must include the miibus in your kernel if 925 you use the ed driver. 926 92720010220: 928 The problems with libc have been corrected. It is now mostly 929 safe to go back into the water. 930 93120010211: 932 The size of FILE was changed. This breaks upgrading. If 933 you must upgrade, be prepared for pain. It also breaks almost 934 all binaries that you've compiled on -current. You are warned 935 that before upgrading would be a good time to do a level 0 936 dump of your system. No, really, I mean it this time. 937 938 To get to the new system, you'll need to use the following 939 workaround. Hopefully this can be sorted out so that we 940 don't have to move this to the updating section. 941 942 To get around the installworld problem, do: 943 # cd /usr/src/usr.bin/sed 944 # make install 945 # cd /usr/src 946 # make installworld 947 If that doesn't work, then try: 948 # make -k installworld 949 # make installworld 950 95120010207: 952 DEVFS is now the default. If you use vinum, make sure that you 953 do not include devfs in your kernel as problems result. 954 95520010205: 956 FFS_ROOT and CD9660_ROOT have been removed or deprecated. 957 Remove them from your config. 958 95920010122: 960 ****************************** WARNING ****************************** 961 buildkernel has been changed slightly 962 ****************************** WARNING ****************************** 963 KERNCONF replaces the variable KERNEL for buildkernel. You 964 should update your scripts and make.conf accordingly. 965 96620010119: 967 config has changed to allow DEV_FOO as a replacement for NFOO. 968 This requires a new config to build correctly. 969 97020010116: 971 The kernel option I386_CPU is now mutually exclusive with the 972 other cpu types. If you have an i386 system, be sure that it 973 only had this line. Remove it for all other configurations. 974 97520010110: 976 Changes to the kernel require it and burncd be in sync. 977 97820010102: 979 Everyone who has hw.sndunit set to something in 980 /etc/sysctl.conf, it is now hw.snd.unit. 981 98220010101: 983 ex and vi were broken by some changes to sys/queue.h. If you 984 have a bad vi, you will see make buildworld fail with a core 985 dump while building termcap. You can work around this problem 986 by adding -k to your make buildworld. This will cause the 987 build to complete and install a new vi. Once that's done, you 988 can rebuild again without the -k to pick up anything that 989 might have been ignored by the -k option. 990 991 Others have suggested that you can just rebuild libc if your 992 vi/ex is dynamically linked, but I've not received any reports 993 of this working. 994 99520001228: 996 There have been some changes to libcrypt in -current. The 997 libscrypt/libdescrypt symlink silliness is gone and the installed 998 libcrypt is fully functional. Be aware of this. 999 100020001218: 1001 Linksys Fast Ethernet PCCARD cards supported by the ed driver 1002 now require the addition of flag 0x80000 to their config line 1003 in pccard.conf(5). This flag is not optional. These Linksys 1004 cards will not be recognized without it. 1005 100620001205: 1007 Important new FreeBSD-version stuff: PAM support has been worked 1008 in, partially from the "Unix" OpenSSH version. This requires 1009 adding the following in pam.conf: 1010 1011 sshd auth sufficient pam_skey.so 1012 sshd auth required pam_unix.so try_first_pass 1013 sshd session required pam_permit.so 1014 101520001031: 1016 cvs updated to 1.11. 1017 101820001020: 1019 The random device needs more entropy, so you need to make sure 1020 that you've run mergemaster to get a /etc/rc which will seed 1021 /dev/random. If you don't and the system hangs after ldconfig, 1022 then banging on the keyboard randomly until it unhangs is one 1023 workaround. 1024 102520001010: 1026 ****************************** WARNING ****************************** 1027 Sendmail has been updated. 1028 ****************************** WARNING ****************************** 1029 o mail.local(8) is no longer installed as a set-user-id binary. 1030 o sendmail(8) is now built with STARTTLS support unless NO_OPENSSL 1031 is set. 1032 o The default /etc/mail/sendmail.cf disables the SMTP EXPN and VRFY 1033 commands. 1034 o Now using sendmail's version of vacation(1). 1035 o The sendmail cf building tools (contrib/sendmail/cf) are installed 1036 in /usr/share/sendmail/cf. 1037 o sendmail.cw changed to local-host-names 1038 1039 More details can be found at 1040 http://people.freebsd.org/~imp/UPDATING/sendmail-20001010 1041 104220001009: 1043 The ports tree's new layout is in place. Be sure to update 1044 your entire ports tree, or you will have problems. 1045 104620001006: 1047 The perl build procedure no longer installs miniperl, nor uses 1048 the installed miniperl. It is recommended that you delete 1049 /usr/bin/miniperl. 1050 105120001005: 1052 This weekend the ports tree will be updated to a new layout. 1053 It will be in an inconsistent state until noted in the UPDATING 1054 file, or with asami-san's message to the relevant mailing 1055 lists. With this new layout, you'll need to update the whole 1056 tree for anything to work. 1057 105820000928: 1059 There was a change in the passwd format. Need more information. 1060 106120000916: 1062 /boot/kernel/kernel.ko -> /boot/kernel/kernel change has taken 1063 place. Please update boot loader (not the boot blocks) at the 1064 same time as your kernel. 1065 106620000914: 1067 The new pmtimer device is necessary for laptops. Failure to 1068 include the device will cause suspended laptops losing time 1069 when they resume. Include 1070 device pmtimer 1071 in your config file and 1072 hint.pmtimer.0.at="isa" 1073 to your /boot/device.hints file. 1074 107520000911: 1076 The random device has been turned into a (pseudo-)device, 1077 rather than an option. The supplied kernel config files have 1078 been updated. You will need to do something similar in your 1079 own kernel config file. 1080 Remove: 1081 options RANDOMDEV 1082 Add: 1083 device random 1084 If you prefer to load the loadable module, you need to do 1085 nothing. 1086 108720000909: 1088 The random device module has been renamed from randomdev.ko to 1089 random.ko. You will need to edit your /boot/loader.conf to 1090 reflect this if you load this module at boot time. 1091 The line should read: 1092 random_load="YES" 1093 109420000907: 1095 The SMPNG commit has happened. It should work, but if it 1096 doesn't, fallback to the PRE_SMPNG CVS tag. There are likely 1097 to be a variety of minor issues. Please see 20000905 to make 1098 sure you don't have model loading problems which might at 1099 first blush appear related to SMP. 1100 110120000906: 1102 nsswitch has been imported from NetBSD. Among other things, 1103 this means that /etc/host.conf is no longer used. See 1104 nsswitch.conf(5) instead. Note that at boot time rc.network 1105 will attempt to produce a new nsswitch.conf file for you if you 1106 don't have one, and you have host.conf. 1107 110820000905: 1109 The ucred structure changed size. This breaks the interface 1110 that mountd uses. Trying to use an older mountd with a newer 1111 kernel guarantees a panic. This means that you need to use 1112 kernels newer than today only with matching mountd, but you 1113 needed to do that anyway with the boot loader changes. 1114 111520000905: 1116 The boot loader has been updated. The new default kernel is 1117 now /boot/kernel/kernel.ko. The new default module location 1118 is /boot/kernel. 1119 1120 You *MUST* upgrade your boot loader and kernel at the same time. 1121 The easiest way to do this is to do the buildworld/buildkernel/ 1122 installkernel/installworld dance. 1123 1124 Furthermore, you are urged to delete your old /modules directory 1125 before booting the new kernel, since kldload will find stale 1126 modules in that directory instead of finding them in the correct 1127 path, /boot/kernel. The most common complaint that this cures 1128 is that the linux module crashes your machine after the update. 1129 1130 if [ ! -d /boot/kernel.old ]; then 1131 mv /modules.old /boot/kernel.old 1132 chflags noschg /kernel.old 1133 mv /kernel.old /boot/kernel.old/kernel.ko 1134 chflags schg /boot/kernel.old/kernel.ko 1135 fi 1136 113720000904: 1138 A new issue with the sendmail upgrade has come to light. 1139 /etc/aliases has moved to /etc/mail/aliases. Mergemaster will 1140 incorrectly install the default aliases in /etc/mail rather than 1141 move the old one from /etc. So you'll need to manually move the 1142 file, create a symbolic link, remove the old /etc/aliases.db and 1143 run newaliases. For safety sake, you should stop sendmail 1144 while doing this and run the upgrade when locally sourced email 1145 is not likely to be generated. 1146 114720000825: 1148 /boot/device.hints is now required for installkernel to 1149 succeed. You should copy GENERIC.hints for your architecture 1150 into /boot/device.hints. If and only if you compile hints 1151 into your kernel, then this file may be empty. Please note, 1152 if you have an empty or missing /boot/device.hints file and 1153 you neglected to compile hints into your kernel, no boot 1154 messages will appear after the boot loader tries to start the 1155 kernel. 1156 115720000821: 1158 If you do NOT have ``options RANDOMDEV'' in your kernel and 1159 you DO want the random device then add randomdev_load="YES" to 1160 /boot/loader.conf. 1161 116220000812: 1163 suidperl is now always built and installed on the system, but 1164 with permissions of 511. If you have applications that use 1165 this program, you are now required to add ENABLE_SUIDPERL=true 1166 to /etc/make.conf. If you forget to do this, 1167 chmod 4511 /usr/bin/suidperl 1168 will fix this until the next build. 1169 117020000812: 1171 sendmail has been updated from 8.9.3 to 8.11.0. Some of the more 1172 visible changes that may immediately affect your configuration 1173 include: 1174 - New default file locations from src/contrib/sendmail/cf/README 1175 - newaliases limited to root and trusted users 1176 - MSA port (587) turned on by default 1177 - New queue file naming system so can't go from 8.11 -> 8.9 1178 - FEATURE(`rbl') renamed to FEATURE(`dnsbl') 1179 - FEATURE(`nullclient') is more full featured 1180 - FEATURE(`nouucp') requires an argument: `reject' or `nospecial' 1181 - mail.local FreeBSD-only -b option changed to -B 1182 - See src/contrib/sendmail/RELEASE_NOTES for more info 1183 118420000810: 1185 suidperl (aka sperl) is no longer build by default. You must 1186 specifically define BUILD_SUIDPERL to "true" for it to be build. 1187 Furthermore, we recommend that you remove /usr/bin/sperl* and 1188 /usr/bin/suidperl files from your system unless you have a 1189 specific use for it. 1190 119120000729: 1192 Networking defaults have been tightened. Anybody upgrading 1193 /etc/defaults/rc.conf needs to add the following lines to 1194 /etc/rc.conf if they want to have the same setup 1195 afterwards (unless the variables already are set, of course): 1196 # Enable network daemons for user convenience. 1197 inetd_enable="YES" 1198 portmap_enable="YES" 1199 sendmail_enable="YES" 1200 120120000728: 1202 If you have null_load="YES" in your /boot/loader.conf, you 1203 will need to change that to nullfs_load="YES". 1204 120520000728: 1206 The "installkernel" target has changed slightly. Now even if 1207 you override KERNEL e.g. 'make installkernel KERNEL=MYKERNEL' 1208 it will install the MYKERNEL file (built with the buildkernel 1209 target) as /kernel rather than /MYKERNEL. Those who have 1210 updated their /boot/loader.conf files to point to /MYKERNEL 1211 should remove that entry or perform manual rename of /kernel 1212 to /MYKERNEL. 1213 121420000711: 1215 If you use CVSUP or CTM to get CVS trees, AND you used to get 1216 the old crypto files from internat.freebsd.org AND you check 1217 out files from the CVS tree with the cvs command, please read 1218 http://people.freebsd.org/~imp/internat.txt 1219 for details on potential problems that you might have and how 1220 to get around them. 1221 1222 If you are merely a mirror, or don't answer yes to each of the 1223 clauses above, you needn't worry. 1224 122520000711: 1226 /etc/security has been updated to print the inode number of 1227 setuid programs that have changed. You will see a large spike 1228 in the number of changed programs the first time when you run 1229 mergemaster to get a new /etc/security. 1230 123120000710: 1232 /dev/random now has good entropy collection (from the keyboard 1233 and sysmouse drivers). Please ensure that either `options 1234 RANDOMDEV' is present in your kernel config file or that 1235 `randomdev_load="YES"' is in your /boot/loader.conf. If you do 1236 not have the /dev/random driver, OpenSSL (and consequently 1237 lots of crypto tools (like SSH)) will fail with strange 1238 errors. (see below, 20000624). 1239 1240 FreeBSD-current is safe again to run Crypto. 1241 124220000709: 1243 phk made the malloc default options AJ. This may slow things 1244 down and uncover other latent bugs in the code. If you need to 1245 run at full speed, you can disable this by doing the following: 1246 ln -s aj /etc/malloc.conf 1247 124820000706: 1249 libftpio's version was accidentally bumped a few days ago. This 1250 has been corrected. You may need to remove /usr/lib/libftpio.so.6 1251 before doing your next buildworld/installworld pair. It certainly 1252 won't hurt to remove it before the update procedure. It will 1253 break fetch until a new one is built, but ftp can be used in the 1254 interim if needed. 1255 125620000705: 1257 The crypto packages have changed for the cvsup. This has been done 1258 in a backward compatible way, but the old packages will go away at 1259 some point in the future. Look at /usr/share/examples/cvsup for 1260 details. 1261 126220000704: 1263 With the new sys/modules/sound/drivers/*, you will need to 1264 set SYSDIR until you do an installworld after July 7th. 1265 126620000704: 1267 rc.shutdown and rc will now call the rc.d scripts with start 1268 or stop. This may cause some harmless warnings from older 1269 rc.d scripts that haven't been updated. 1270 127120000630: 1272 The libfetch based version of fetch has gone into the tree. 1273 Minor problems may result on some of the less popular sites, 1274 which should be reported to des@freebsd.org. 1275 127620000625: 1277 From approximately this date forward, one must have the crypto 1278 system installed in order to build the system and kernel. 1279 While not technically strictly true, one should treat it as 1280 required and grab the crypto bits. If you are grabbing CVS 1281 trees, src-all and cvs-crypto should be treated as if they 1282 were required. You should check with the latest collections 1283 to make sure that these haven't changed. 1284 128520000624: 1286 Mark Murray just committed the first parts of a cleanup of 1287 /dev/zero, et al. This is also cleaning up /dev/random. 1288 The entropy is disconnected, so DO NOT USE VERSIONS OF FREEBSD 1289 -CURRENT FROM THIS POINT to 2000710 for cryptographic services 1290 until Mark can merge in the fixes to this work in progress. 1291 openssh and openssl should not be used to generate keys from this 1292 date to the completion of the work. 1293 1294 If you must operate at this reduced level of security, add ' 1295 options RANDOMDEV' to your kernel or modload the randomdev 1296 module. You may also need to copy a new MAKEDEV to /dev and 1297 recreate the random and urandom devices. 1298 129920000622: 1300 The license on the softupdates is now a standard 2 clause 1301 BSD license. You may need to remove your symbolic links 1302 that used to be required when updating. 1303 130420000621: 1305 Scott Flatman <sf@aracnet.com> sent in a decent write-up on 1306 the config file update procedure. 1307 http://people.freebsd.org/~imp/config-upd.html 1308 NOTE: LINT is gone. It has been replaced with NOTES. NOTES 1309 isn't buildable. However, you can generate a LINT file: 1310 cd /sys/<ARCH>/conf && make LINT 1311 131220000620: 1313 Binutils 2.10 have hit the tree, or will shortly. As soon 1314 as they do, the problem noted in 20000522 will be resolved and 1315 that workaround will no longer be required. 1316 131720000615: 1318 phk removed the compatibility creation of wd devices in the 1319 ad driver. If you haven't done so already, you must update 1320 your fstab, etc to use the ad devices instead of the wd 1321 devices. 1322 1323 In addition, you'll need to update your boot blocks to a 1324 more modern version, if you haven't already done so. Modern 1325 here means 4.0 release or newer (although older releases 1326 may work). 1327 132820000612: 1329 Peter took an axe to config(8). Be sure that you read his mail 1330 on the topic before even thinking about updating. You will 1331 need to create a /boot/device.hints or add a hints directive 1332 to your config file to compile them in statically. The format 1333 of the config file has changed as well. Please see GENERIC or 1334 NEWCARD for examples of the new format. 1335 1336 Indirectly, this also breaks USERCONFIG. Unless a newer entry 1337 says that it has been fixed, assume that must use the hints mechanism 1338 in the loader if you need to use a machine with very old ISA cards 1339 in it. 1340 134120000522: 1342 A new set of binutils went into the tree today. Anybody 1343 building a kernel after this point is advised that they need 1344 to rebuild their binutils (or better yet do a 1345 buildworld/installworld) before building a new kernel. 1346 1347 Due to bugs in binutils, using malloc options (eg /etc/malloc.conf 1348 or MALLOC_OPTIONS env var) J will cause ld to dump core. It 1349 is recommended that you don't set this option until the problem 1350 is resolved. 1351 135220000513: 1353 The ethernet drivers were all updated to clean up the BPF handling. 1354 135520000510: 1356 The problems with boot blocks on the alphas have been corrected. 1357 This will require some care in updating alphas. A new libstand 1358 is requires for the boot blocks to build properly. 1359 136020000503: 1361 Recompile all kld modules. Proper version dependency info 1362 is now available. 1363 136420000502: 1365 Modules have been disconnected from the buildworld tree and 1366 connected to the kernel building instead. 1367 136820000427: 1369 You may need to build gperf 1370 cd /usr/src/gnu/usr.bin/gperf && make depend all install 1371 when upgrading from 4.0 -> current. The build system now uses 1372 an option only in -current. 1373 137420000417: 1375 The method that we brand ELF binaries has changed to be more 1376 acceptable to the binutils maintainers. You will need to 1377 rebrand your ELF binaries that aren't native. One problem 1378 binary is the Linux ldconfig. After your make world, but 1379 before you reboot, you'll need to issue: 1380 brandelf -t Linux /compat/linux/sbin/ldconfig 1381 if you have Linux compatibility enabled on your machine. 1382 138320000320: 1384 If you have really bad/marginal IDE drives, you may find they 1385 don't work well. Use pio mode instead. The easiest way to 1386 cope if you have a problem combination is to add: 1387 /sbin/sysctl hw.ata.ata_dma=0 1388 to the start of /etc/rc.conf. 1389 139020000319: 1391 The ISA and PCI compatibility shims have been connected to the 1392 options COMPAT_OLDISA and COMPAT_OLDPCI. If you are using old 1393 style PCI or ISA drivers (i.e. tx, voxware, etc.) you must 1394 include the appropriate option in your kernel config. Drivers 1395 using the shims should be updated or they won't ship with 1396 5.0-RELEASE, targeted for 2001. 1397 139820000318: 1399 We've entered the traditional post release dumping party. 1400 Large kernel changes are being committed and are in the 1401 works. It is important to keep the systems' klds and kernel 1402 in sync as kernel interfaces and structures are changing. 1403 Before reporting kernel panics, make sure that all modules 1404 that you are loading are up to date. 1405 140620000315: 1407 If you are upgrading from an older version of FreeBSD, you 1408 need to update your boot blocks as well. 'disklabel -B ad0' 1409 will do the trick. This isn't critical until you remove your 1410 wd device entries in /dev, at which point your system will not 1411 boot. 1412 141320000315: 1414 4.0 RELEASE shipped. Please see the 4.0 UPDATING file for how 1415 to upgrade to 4.0 from 3.x. 1416 1417COMMON ITEMS: 1418 1419 General Notes 1420 ------------- 1421 Avoid using make -j when upgrading. From time to time in the 1422 past there have been problems using -j with buildworld and/or 1423 installworld. This is especially true when upgrading between 1424 "distant" versions (eg one that cross a major release boundary 1425 or several minor releases, or when several months have passed 1426 on the -current branch). 1427 1428 Sometimes, obscure build problems are the result of environment 1429 poisoning. This can happen because the make utility reads its 1430 environment when searching for values for global variables. 1431 To run your build attempts in an "environmental clean room", 1432 prefix all make commands with 'env -i '. See the env(1) manual 1433 page for more details. 1434 1435 To build a kernel 1436 ----------------- 1437 If you are updating from a prior version of FreeBSD (even one just 1438 a few days old), you should follow this procedure. With a 1439 /usr/obj tree with a fresh buildworld, 1440 make -DALWAYS_CHECK_MAKE buildkernel KERNCONF=YOUR_KERNEL_HERE 1441 make -DALWAYS_CHECK_MAKE installkernel KERNCONF=YOUR_KERNEL_HERE 1442 1443 To just build a kernel when you know that it won't mess you up 1444 -------------------------------------------------------------- 1445 This assumes you are already running a 5.X system. Replace 1446 ${arch} with the architecture of your machine (e.g. "i386", 1447 "alpha", "amd64", "ia64", "pc98", "sparc64", etc). 1448 1449 cd src/sys/${arch}/conf 1450 config KERNEL_NAME_HERE 1451 cd ../compile/KERNEL_NAME_HERE 1452 make depend 1453 make 1454 make install 1455 1456 If this fails, go to the "To build a kernel" section. 1457 1458 To rebuild everything and install it on the current system. 1459 ----------------------------------------------------------- 1460 # Note: sometimes if you are running current you gotta do more than 1461 # is listed here if you are upgrading from a really old current. 1462 1463 <make sure you have good level 0 dumps> 1464 <maybe fix /etc/fstab> [7] 1465 make buildworld 1466 make buildkernel KERNCONF=YOUR_KERNEL_HERE 1467 make installkernel KERNCONF=YOUR_KERNEL_HERE 1468 [1] 1469 <reboot in single user> [3] 1470 /etc/rc.d/preseedrandom [10] 1471 mergemaster -p [5] 1472 make installworld 1473 mergemaster [4] 1474 <reboot> 1475 1476 1477 To cross-install current onto a separate partition 1478 -------------------------------------------------- 1479 # In this approach we use a separate partition to hold 1480 # current's root, 'usr', and 'var' directories. A partition 1481 # holding "/", "/usr" and "/var" should be about 2GB in 1482 # size. 1483 1484 <make sure you have good level 0 dumps> 1485 <boot into -stable> 1486 make buildworld 1487 <maybe newfs current's root partition> 1488 <mount current's root partition on directory ${CURRENT_ROOT}> 1489 make installworld DESTDIR=${CURRENT_ROOT} 1490 make buildkernel KERNCONF=YOUR_KERNEL_HERE 1491 cp /usr/src/sys/${ARCH}/conf/GENERIC.hints \ 1492 ${CURRENT_ROOT}/boot/device.hints # as needed 1493 make installkernel KERNCONF=YOUR_KERNEL_HERE DESTDIR=${CURRENT_ROOT} 1494 cd /usr/src/etc; make distribution DESTDIR=${CURRENT_ROOT} # if newfs'd 1495 cp /etc/fstab ${CURRENT_ROOT}/etc/fstab # if newfs'd 1496 <edit ${CURRENT_ROOT}/etc/fstab to mount "/" from the correct partition> 1497 <reboot into current> 1498 <do a "native" rebuild/install as described in the previous section> 1499 <maybe install compatibility libraries from /usr/src/lib/compat> 1500 <reboot> 1501 1502 1503 To upgrade in-place from 4.x-stable to current 1504 ---------------------------------------------- 1505 # 5.x uses more space than 4.x. Also, the location of kernel 1506 # modules has changed. If you are installing 5.0 onto a 4.x 1507 # system, you'll need about 30MB of free disk space on your / 1508 # partition. If you have less than this, you may encounter difficult 1509 # to back out of problems with this procedure. If /tmp is on 1510 # the / partition, you may want to completely remove all its content 1511 # before upgrading, as this can be a common source of shortage of 1512 # space on /. 1513 1514 <make sure you have good level 0 dumps> 1515 <maybe fix /etc/fstab> [7] 1516 make buildworld [9] 1517 make buildkernel KERNCONF=YOUR_KERNEL_HERE [8] 1518 cp src/sys/${MACHINE}/conf/GENERIC.hints /boot/device.hints [2] 1519 make installkernel KERNCONF=YOUR_KERNEL_HERE 1520 cd src/sys/boot ; make install [6] 1521 [1] 1522 <reboot in single user> [3] 1523 /etc/rc.d/preseedrandom [10] 1524 mergemaster -p [5] 1525 rm -rf /usr/include/g++ 1526 make installworld 1527 mergemaster [4] 1528 <reboot> 1529 1530 Make sure that you've read the UPDATING file to understand the 1531 tweaks to various things you need. At this point in the life 1532 cycle of current, things change often and you are on your own 1533 to cope. The defaults can also change, so please read ALL of 1534 the UPDATING entries. 1535 1536 Also, if you are tracking -current, you must be subscribed to 1537 freebsd-current@freebsd.org. Make sure that before you update 1538 your sources that you have read and understood all the recent 1539 messages there. If in doubt, please track -stable which has 1540 much fewer pitfalls. 1541 1542 [1] If you have third party modules, such as vmware, you 1543 should disable them at this point so they don't crash your 1544 system on reboot. 1545 1546 [2] If you have legacy ISA devices, you may need to create 1547 your own device.hints to reflect your unique hardware 1548 configuration. 1549 1550 [3] From the bootblocks, boot -s, and then do 1551 fsck -p 1552 mount -u / 1553 mount -a 1554 cd /usr/src 1555 adjkerntz -i # if CMOS is wall time 1556 Also, when doing a major release upgrade, it is required that 1557 you boot into single user mode to do the installworld. 1558 For the 4.x -> 5.0 upgrade, you will also see many messages about 1559 needing to recompile your userland. These are harmless and can 1560 be ignored while you proceed to the next step. 1561 1562 [4] Note: This step is non-optional. Failure to do this step 1563 can result in a significant reduction in the functionality of the 1564 system. Attempting to do it by hand is not recommended and those 1565 that pursue this avenue should read this file carefully, as well 1566 as the archives of freebsd-current and freebsd-hackers mailing lists 1567 for potential gotchas. 1568 1569 [5] Usually this step is a noop. However, from time to time 1570 you may need to do this if you get unknown user in the following 1571 step. It never hurts to do it all the time. You may need to 1572 install a new mergemaster (cd src/usr.sbin/mergemaster && make 1573 install) after the buildworld before this step if you last updated 1574 from current before 20020224 or from -stable before 20020408. 1575 1576 [6] 4.x boot loader can be used to boot a 5.x system, however 1577 it is difficult to do that at best. If you wish to try, then 1578 you should interrupt the boot and at the ok prompt type: 1579 ok unload 1580 ok boot /boot/kernel/kernel 1581 If this fails to work, you must install a new boot loader as 1582 described here. 1583 1584 [7] Before you upgrade, please make sure that you are not using 1585 compatibility slices. These are device names of the form, on i386 1586 and other architectures that use MBR slicing, /dev/ad0a without the 1587 actual slice name. Chances are excellent that these will break. 1588 You generally must update these entries to use the post FreeBSD 1589 2.x form of /dev/ad0s1a. 1590 1591 [8] In order to have a kernel that can run the 4.x binaries 1592 needed to do an installworld, you must include the COMPAT_FREEBSD4 1593 option in your kernel. Failure to do so may leave you with a system 1594 that is hard to boot to recover. 1595 1596 [9] When checking out sources, you must include the -P flag to have 1597 cvs prune empty directories. 1598 1599 [10] In order to create temporary files, /dev/random must be 1600 initialized by feeding data into it. /etc/rc.d/preseedrandom 1601 takes care of this. 1602FORMAT: 1603 1604This file contains a list, in reverse chronological order, of major 1605breakages in tracking -current. Not all things will be listed here, 1606and it only starts on March 15, 2000.
