UPDATING revision 132840
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 2020030728: 21 System compiler has been upgraded to GCC 3.4.2-pre. As with any major 22 compiler upgrade, there are several issues to be aware of. GCC 3.4.x 23 has broken C++ ABI compatibility with previous releases yet again 24 and users will have to rebuild all their C++ programs with the new 25 compiler. A new unit-at-a-time optimization mode, which is default 26 in this compiler release, is more aggressive in removing unused 27 static symbols. This is the likely cause of 'make buildworld' 28 breakages with non-default CFLAGS where optimization level is set 29 to -O2 or higher. 30 3120040727: 32 The size of 'struct ifnet' has changed due to the addition of 33 the IFF_NEEDSGIANT flag (and what it implies). All kernel 34 modules implementing network interfaces must be recompiled as 35 a result. 36 3720040716: 38 The sound device drivers are renamed. `sound' is always required, 39 while `snd_*' should be configured accordingly to your hardware. 40 Refer to NOTES for the detail of the drivers. 41 4220040710: 43 __FreeBSD_version bumped to 502122. 44 4520040710: 46 The console initialization on Alpha has been reworked and is now 47 identical to other platforms. This means that the hardcoding of 48 the serial console and the debug port has been removed. As such, 49 hints are now required for the sio(4) driver to become a console 50 or debug port. The NO_SIO option has been decommissioned because 51 of this. 52 5320040710: 54 A revamp of the debugging code in the kernel with some visible 55 changes beyond just the debugging experience: 56 o The DDB option is now specific to the DDB debugger backend 57 and should not be used any more for conditional compilation 58 of debugging code for when debugging is enabled. Use the KDB 59 option for this. 60 o The WITNESS_DDB, DDB_TRACE and DDB_UNATTENDED options have 61 been renamed to WITNESS_KDB, KDB_TRACE and KDB_UNATTENDED 62 respectively. This is in line with the first bullet. 63 o The remote GDB support has been untangled from DDB and needs 64 to be enabled separately now. Use the GDB option for this. 65 o The GDB_REMOTE_CHAT option has been removed. Support for this 66 homegrown feature is discontinued. The GDB remote protocol 67 supports console output and it makes sense to use that. 68 o The DDB_NOKLDSYM option has been removed. The DDB debugger 69 now supports both direct symbol table lookups as well as KLD 70 symbol lookups through the linker. 71 7220040708: 73 Bluetooth code has been marked as non-i386 specific. 74 __FreeBSD_version has been bumped to 502121 to mark this change. 75 7620040702: 77 The native preemption has been added to the kernel scheduler. 78 There is some report that the ULE scheduler was broken in some 79 machines and we encourage users using the ULE scheduler either 80 stick with a known good kernel, or temporarily switch to the 4BSD 81 scheduler as a workaround. 82 8320040630: 84 The netgraph ABI version number has been incremented to indicate 85 an incompatible change in the ABI. Old netgraph nodes will refuse 86 to attach until recompiled. Netgraph now uses mbuf tags to move 87 metadata and this commit removes its home-grown metadata facility. 88 Nodes should just recompile, unless they use metadata, in which 89 case the changes are simple; the file ng_ksocket.c serves as an 90 example of such changes. 91 92 This also broke i4b, although the compile problem has been papered 93 over. 94 9520040630: 96 ACPI has been updated to disable known-bad BIOS revisions. A message 97 will be printed on the console indicating that ACPI has been disabled 98 automatically and that the user should use a newer BIOS, if possible. 99 If you think ACPI does work on your system and want to override 100 this (i.e., for testing), set hint.acpi.0.disabled="0" at the 101 loader prompt. 102 10320040623: 104 pf was updated to OpenBSD-stable 3.5 and pflogd(8) is privilege 105 separated now. It uses the newly created "_pflogd" user/group 106 combination. If you plan to use pflogd(8) make sure to run 107 mergemaster -p or install the "_pflogd" user and group manually. 108 10920040622: 110 Network interface cloning has been overhauled. This change will 111 require a recompile of modules using cloning and modification of 112 external ones to the new API. __FreeBSD_version has been bumped 113 to 502119 to mark this change. Additionally, users creating 114 stf(4) interfaces via "ifconfig stf" will need to update their 115 scripts as this will create an interface named "stf" instead of 116 "stf0" and ifconfig will not print "stf0" to stdout. 117 11820040621: 119 On 20040524, the /etc/rc.d/nsswitch script was modified to 120 automatically create /etc/nsswitch.conf on startup if it did 121 not already exist. Unfortunately, an error in the man page 122 was carried over to the script, resulting in incorrect 123 nsswitch settings. The simplest remedy is to remove both 124 /etc/nsswitch.conf and /etc/host.conf; they will be recreated 125 during the next reboot. 126 12720040614: 128 The return value of sema_timedwait(9) has been changed to 129 make it consistent with cv_timedwait(9). Be sure to recompile 130 the ips module and any third-party modules which call 131 sema_timedwait. 132 13320040613: 134 ALTQ is now linked to the build. This breaks ABI for struct ifnet. 135 Make sure to recompile modules and any userland that makes use of 136 sizeof(struct ifnet). In order to get the altq headers in place 137 please recompile and reinstall world. 138 13920040607: 140 Splitting kern_thread.c into 2 files (adding kern_kse.c) 141 requires that you re-run config after updating your tree. 142 14320040601: 144 The MIDI drivers have been removed. Until the new module-friendly 145 ones are merged, remove or comment out midi and seq from your 146 kernel configuration. 147 14820040423: 149 Due to a new option in ipfw (versrcreach) the ipfw(8) command 150 needs to be recompiled. Normal accept/reject rules without 151 options are not affected but those with options may break until 152 ipfw(8) is recompiled. 153 15420040420: 155 Due to changes in the callout ABI, kernels compiled after this 156 date may be incompatible with kernel modules compiled prior to 157 20040406. 158 15920040414: 160 The PCI bus power state stuff has been turned on. If this causes 161 problems for your system, please disable it using the tunable 162 hw.pci.do_powerstate=0. 163 16420040412: 165 The bulk of the pci problems have been fixed, although the floppy 166 drive is still broken. 167 16820040410: 169 A substantial update to the pci bus resource and power management 170 have been committed. Expect a bumpy ride for a few days until 171 the unanticipated problems have been resolved. 172 17320040409: 174 Due to changes in the the Yarrow initialization process, 175 /dev/random needs to be fed before operations requiring 176 temp files can succeed in single user mode. This includes 177 running "make installworld". /dev/random may be fed by running 178 "/etc/rc.d/initrandom start" or with 20040415 source by running 179 "/etc/rc.d/preseedrandom". 180 18120040322: 182 The debug.mpsafenet tunable controls whether the kernel Giant 183 lock is held across the lower levels of the network stack, and 184 by default is turned off. In the few days following 20040322, 185 the behavior of debug.mpsafenet will change such that this 186 tunable controls Giant over all levels of the network stack. 187 If you are currently setting debug.mpsafenet to 1, you should 188 set it back to 0 (the default) again during the change-over. 189 An additional note will be added to UPDATING when sufficient 190 locking is merged to permit this to take place. 191 19220040310: 193 The FreeBSD/sparc64 platform is changing time_t from 32-bits to 194 64-bits. This is a very major incompatible change, so people 195 using FreeBSD/sparc64 *must* read the UPDATING.64BTT file for 196 detailed instructions on how to make this upgrade. People 197 upgrading FreeBSD on other platforms can ignore this event. 198 19920040308: 200 The packet filter (pf) is now installed with the base system. Make 201 sure to run mergemaster -p before installworld to create required 202 user account ("proxy"). If you do not want to build pf with your 203 system you can use the NO_PF knob in make.conf. 204 Also note that pf requires "options PFIL_HOOKS" in the kernel. The 205 pf system consists of the following three devices: 206 device pf # required 207 device pflog # optional 208 device pfsync # optional 209 21020040303: 211 If you are having trouble with the libc_r -> libpthread transition 212 (see the 20040130 entry), place the following lines at the top of 213 /etc/libmap.conf: 214 215 libc_r.so.5 libpthread.so.1 216 libc_r.so libpthread.so 217 218 This will cause all programs and libraries linked against libc_r 219 to use libpthread instead. 220 22120040226: 222 Some sshd configuration defaults have changed: protocol version 1 223 is no longer enabled by default, and password authentication is 224 disabled by default if PAM is enabled (which it is by default). 225 OpenSSH clients should not be affected by this; other clients may 226 have to be reconfigured, upgraded or replaced. 227 22820040225: 229 The ABIs defined in <resolv.h> and <netdb.h> have been updated 230 to support improved reentrancy. Multi-threaded programs that 231 reference the "_res" or "h_errno" symbols may experience some 232 problems if they are not recompiled. Single-threaded programs 233 should remain unaffected. 234 23520040225: 236 routed has been updated in the base system from the vendor 237 sources, routed v2.27, from rhyolite.com. This change means that 238 for users who use RIP's MD5 authentication feature, FreeBSD 239 -CURRENT's routed is now incompatible with previous versions 240 of FreeBSD; however it is now compatible with implementations 241 from Sun, Cisco and other vendors. 242 24320040224: 244 The tcpcb structure has changed and makes a recompile of libkvm 245 and related userland network utilities necessary. 246 24720040222: 248 The cdevsw structure has changed in two externally visible ways. 249 First, the sense of the D_GIANT flag has changed to D_NEEDSGIANT. 250 Second, the d_version field must be filled in with D_VERSION. 251 Drivers outside the tree will need to be updated. 252 25320040207: 254 The /etc/rc.d/ttys script has been removed. It is no longer 255 necessary since devfs has been mandatory for some time. 256 25720040130: 258 libkse has been renamed back to libpthread and is now the 259 default threads library. The gcc -pthread option has also 260 been changed to link to libpthread instead of libc_r. For 261 alpha and sparc64 machines, libkse is not renamed and links 262 are installed so that libpthread points to libc_r. Until 263 the ports system is updated to handle this change, it is 264 recommended that folks install an /etc/libmap.conf(5) that 265 maps libc_r to libpthread. If you have any binaries or 266 libraries linked to libkse, then it is also recommended 267 that you map libkse to libpthread. Anyone that is using 268 nvidia supplied drivers and libraries should use a libmap.conf 269 that maps libpthread to libc_r since their drivers/libraries 270 do not work with libpthread. 271 27220040125: 273 ULE has entered into its probationary period as the default scheduler 274 in GENERIC. For the average user, interactivity is reported to be 275 better in many cases. On SMP machines ULE will be able to make more 276 efficient use of the available parallel resources. If you are not 277 running it now, please switch over, replacing the kernel option 278 SCHED_4BSD with SCHED_ULE. 279 28020040125: 281 Move LongRun support out of identcpu.c, where it hardly 282 belongs, into its own file and make it opt-in, not mandatory, 283 depending on CPU_ENABLE_LONGRUN config(8) option. 284 28520031213: 286 src/lib/libc/gen/initgroups.c:1.8 now causes logins to fail 287 if the login process is unable to successfully set the 288 process credentials to include all groups defined for the 289 user. The current kernel limit is 16 groups; administrators 290 may wish to check that users do not have over 16 groups 291 defined, or they will be unable to log in. 292 29320031203: 294 The ACPI module has been reactivated. It is no longer required 295 to compile ACPI support into kernels statically. 296 29720031112: 298 The statfs structure has been updated with 64-bit fields to 299 allow accurate reporting of multi-terabyte filesystem 300 sizes. You should build world, then build and boot the new kernel 301 BEFORE doing a `installworld' as the new kernel will know about 302 binaries using the old statfs structure, but an old kernel will 303 not know about the new system calls that support the new statfs 304 structure. 305 Note that the backwards compatibility is only present when the 306 kernel is configured with the COMPAT_FREEBSD4 option. Since 307 even /bin/sh will not run with a new kernel without said option 308 you're pretty much dead in the water without it. Make sure you 309 have COMPAT_FREEBSD4! 310 Running an old kernel after a `make world' will cause programs 311 such as `df' that do a statfs system call to fail with a bad 312 system call. Marco Wertejuk <wertejuk@mwcis.com> also reports 313 that cfsd (ports/security/cfs) needs to be recompiled after 314 these changes are installed. 315 316 ****************************DANGER******************************* 317 318 DO NOT make installworld after the buildworld w/o building and 319 installing a new kernel FIRST. You will be unable to build a 320 new kernel otherwise on a system with new binaries and an old 321 kernel. 322 32320031112: 324 Some netgraph string length constants have been changed. This 325 change requires the netgraph kernel modules and all netgraph 326 userland components to be in sync. Especially users who require 327 netgraph to boot need to make sure to have world and kernel in 328 sync before rebooting. 329 33020031111: 331 Hyperthreading logical CPU's are no longer probed by default 332 when using the MP Table. If ACPI is being used, then logical 333 CPUs will be probed if hyperthreading is enabled in the BIOS. 334 If ACPI is not being used and hyperthreading is enabled in the 335 BIOS, logical CPUs can be enabled by building a custom kernel 336 with the option MPTABLE_FORCE_HTT enabled. 337 33820031103: 339 The i386 APIC_IO kernel option has been replaced by 340 'device apic'. The ACPI module has also been temporarily 341 disabled, so ACPI must be statically compiled into your 342 kernel using 'device acpi' if you wish to use the ACPI driver. 343 34420031031: 345 The API and ABI of struct ifnet have been changed by removing 346 the if_name and if_unit members and replacing them with 347 if_xname, if_dname, and if_dunit. All network drivers and most 348 userland programs which include net/if_var.h must be updated 349 and recompiled. __FreeBSD_version has been bumped to 501113 to 350 reflect this change. 351 35220030928: 353 Changes to the cdevsw default functions have been made to remove 354 the need to specify nullopen() and nullclose() explicitly. 355 __FreeBSD_version bumped to 501110. 356 35720030926: 358 kiconv(3) has been added. mount_msdosfs(8), mount_ntfs(8) and 359 mount_cd9660(8) need to be in sync with kernel. 360 36120030925: 362 Configuring a system to use IPFILTER now requires that PFIL_HOOKS 363 also be explicitly configured. Previously this dependency was 364 magically handled through some cruft in net/pfil.h; but that has 365 been removed. Building a kernel with IPFILTER but not PFIL_HOOKS 366 will fail with obtuse errors in ip_fil.c. 367 36820030923: 369 Fix a bug in arplookup(), whereby a hostile party on a locally 370 attached network could exhaust kernel memory, and cause a system 371 panic, by sending a flood of spoofed ARP requests. See 372 FreeBSD-SA-03:14.arp. 373 37420030915: 375 A change to /etc/defaults/rc.conf now causes inetd to be started 376 with `-C 60' if it is not overridden in /etc/rc.conf. This 377 causes inetd to stop accepting connections from an IP address 378 that exceeds the rate of 60 connections per minute. 379 38020030829: 381 The following rc.d scripts have been removed and should be 382 deleted from your installation: atm2.sh atm3.sh devdb 383 localdaemons network1 network2 network3. Depending on when 384 you last updated world and used mergemaster(8) you may or 385 may not have problems during the rc boot sequence. The simplest 386 solution is an 'rm -rf /etc/rc.d/*' and then 'mergemaster -i'. 387 The atm2.sh atm3.sh and devdb scripts were removed some time 388 ago, so depending on when you installed -CURRENT these scripts 389 may or may not exist on your system. 390 39120030824: 392 ATAng has been committed. You need to build world as sys/ata.h 393 has changed, and userland atacontrol depends on it. 394 If you use ATA SW raids you need "device ataraid" in your 395 kernel config file, as it is no longer pulled in automatically. 396 39720030819: 398 The OFW_NEWPCI option has been turned on in the Sparc64 GENERIC kernel. 399 Among other things, this changes the device enumeration to be 400 closer to Solaris. Be aware that, this can even cause the machine 401 to not boot without manual intervention before the fstab is adjusted. 402 40320030728: 404 All current USB and Firewire quirks in da(4) have been deprecated 405 and will be removed for 5.2. If this causes failure for your 406 umass(4) devices, enable "options DA_OLD_QUIRKS" in your kernel 407 and send the output of "camcontrol inquiry da0" to scsi@freebsd.org 408 so the quirk can be re-enabled. 409 41020030724: 411 Problems with entry 20030714 have been corrected and no known issues 412 with /rescue and -j exist for host systems after this point in time. 413 41420030722: 415 FPU-less support has been removed from FreeBSD. Chances are you won't 416 notice. 386+387 support should still work after this change, but 417 it is now a minimum requirement for the i386 port that you have real 418 FPU hardware. 419 42020030714: 421 Some people are having problems with changes related to /rescue. 422 If you are building -j N, you will need to define NO_RESCUE. Others 423 will need to define it if /rescue has issues with their environment. 424 People should report those issues to current@. 425 42620030711: 427 gcc was upgraded to 3.3. You are advised to not build -DNOCLEAN 428 across this point. Further, it might be a good idea to remove 429 /usr/obj. 430 43120030610: 432 Remove deprecated locale names and transition period code 433 for them, finishing switching to the new scheme. Check your 434 LANG environment variable. 435 43620030609: 437 CCD has been changed to be a fully GEOMified class. Kernel 438 and ccdconfig(8) needs to be in sync, this is particularly 439 important to remember beforehand if your source tree is on 440 a ccd device. Consider making a copy of the old ccdconfig 441 into /boot/kernel.good or wherever you keep your backup 442 kernel. 443 44420030605: 445 There was a small window in which sed(1) was broken. If you 446 happen to have sed(1) installed during that window, which is 447 evidenced by an inability to build world with the failure 448 given below, you need to manually build and install sed(1) 449 (and only sed(1)) before doing anything else. This is a one- 450 time snafu. Typical failure mode: 451 452 In file included from /usr/src/contrib/binutils/bfd/targets.c:1092: 453 targmatch.h:7:1: null character(s) ignored 454 targmatch.h:12:1: null character(s) ignored 455 targmatch.h:16:1: null character(s) ignored 456 : 457 458 The window of "sed(1)-uction" is from Wed Jun 4 15:31:55 2003 UTC 459 to Thu Jun 5 12:10:19 2003 UTC (from rev 1.30 to rev 1.31 of 460 usr.bin/sed/process.c). 461 46220030505: 463 Kerberos 5 (Heimdal) is now built by default. Setting 464 MAKE_KERBEROS5 no longer has any effect. If you do NOT 465 want the "base" Kerberos 5, you need to set NO_KERBEROS. 466 46720030502: 468 groff has been updated. If you try to do a buildworld and 469 get an infinite loop in troff, update to May 4th or newer. If you 470 have a newer kernel than userland, you may need to set the OSRELDATE 471 to 500110 in your environment before starting a buildworld. 472 47320030501: 474 The old rc system has been removed. Please report any problems 475 to freebsd-rc@yahoogroups.com, and/or freebsd-current@freebsd.org. 476 Your personal versions of these files will not be removed, so you can 477 continue to use them. However, you should take great care when updating, 478 especially when using mergemaster, since the compatibility code that 479 utilizes these old scripts has also been removed. 480 48120030423: 482 A bug has been fixed in /dev/devctl which would cause devd 483 to hang on boot, were it not for a workaround in devd. The 484 work around in devd will be removed around 20030507. You 485 have until then to upgrade your kernel before updating 486 userland. In general, you should have a userland and 487 kernel that's in sync with each other. However, given the 488 effects of this bug (hang on boot when starting devd), some 489 allowances are made. 490 49120030329: 492 Alphas with libc from between 20030312 and 20030329 exhibit 493 floating point exceptions (FPEs), most notably in awk(1) 494 while upgrading the system through a buildworld. 495 496 So, to successfully upgrade your Alpha, you must either 497 downgrade your libc.so to a pre-20030312 version, or update 498 /usr/share/mk/bsd.cpu.mk to revision 1.26 which adds -mieee 499 to CFLAGS, then forcibly rebuild and install libc: 500 501 cd /usr/src/lib/libc && \ 502 make cleandir && make obj && \ 503 make -DNOMAN -DNOPROFILE all && \ 504 make -DNOMAN -DNOPROFILE install 505 50620030208: 507 sendmail 8.12.7 has been imported. It has one important 508 change for IPv6 users. The default submit.mc now uses 509 '[127.0.0.1]' instead of 'localhost' meaning only IPv4 is 510 used to connect to the MTA. Users on IPv6-only machines 511 will need to edit /etc/mail/submit.mc appropriately. 512 51320030128: 514 NODEVFS option has been removed and DEVFS thereby made standard. 515 This makes all references to MAKEDEV obsolete, and they should 516 be removed when convenient. 517 51820030126: 519 The name of the device for the ofw console has changed, sparc64 users 520 must run mergemaster to update their installed /etc/ttys. 521 52220030125: 523 The scheduler framework has grown a second scheduler and consequently 524 you must specify one and only one scheduler in your kernel config. 525 The cvs config files have been updated to use the old scheduler 526 which may be selected via 'options SCHED_4BSD'. If you would like 527 to try the new, much more experimental, scheduler please try 528 'options SCHED_ULE' and contribute to the arch@ discussion. 529 53020030115: 531 A new version of the wi driver has been imported into the tree. 532 One now must have device wlan in the config file for it to operate 533 properly. 534 535 In addition, there have been some changes to how wi devices are 536 configured for point to point links to bring it more in line 537 with the former way of doing things, as well as compatibility 538 with NetBSD. 539 54020021222: 541 For a period after the GCC 3.2.1 import (from 12/04 to 12/22), GCC 542 used an incompatible form of ABI for returning structures and unions 543 which FreeBSD's GCC maintainers were not aware of relative to previous 544 versions of FreeBSD. We have gone back to the ABI for now, and any 545 code compiled which is required to interoperate with other code (not 546 built at the same time) returning structs or unions should be 547 rebuilt. 548 54920021216: 550 A name change in /etc/netconfig has been reverted to stay 551 compatible with suns TIRPC and also with NetBSD. You need 552 to run mergemaster after make world. A new libc does still work 553 with an outdated /etc/netconfig for some time, but you'll get 554 a warning. This warning will be removed in 20030301. 555 55620021202: 557 The recent binutils upgrade marks a kernel flag day on 558 sparc64: modules built with the old binutils will not work 559 with new kernels and vice versa. Mismatches will result in 560 panics. Make sure your kernel and modules are in sync. 561 56220021029: 563 The value of IPPROTO_DIVERT has changed. Make sure to keep 564 your kernel, netstat, natd and any third-party DIVERT 565 consumers in sync. 566 56720021024: 568 Old, compatibility slices have been removed in GEOM kernels. 569 This means that you will have to update your /etc/fstab to 570 not use disk devices of the form /dev/ad0a. Instead, you 571 now must specify /dev/ad0s1a, or whatever slice your FreeBSD 572 partition really is on. The old device names have gone 573 away, so if you use them anywhere else, you must also adjust 574 those uses. (This doesn't affect the disks formatted in 575 the ``dangerously-dedicated'' mode.) 576 57720021023: 578 Alphas with kernels from between 20020830 and 20021023 and/or 579 rtld (ld-elf.so.1) older than 20021023 may experience problems 580 with groff while doing a buildworld (kernel: "out of memory", 581 fixed in rev 1.129 of kern/imgact_elf.c; rtld: "too few PT_LOAD 582 segments", fixed in rev 1.8 of libexec/rtld-elf/map_object.c). 583 584 So, to successfully upgrade your Alpha, you must either 585 upgrade your kernel and rtld first (which might be a bit 586 tricky), or avoid running the bootstrapped groff during the 587 "transitional" buildworld. To avoid running groff during the 588 transitional upgrade run make buildworld with -DNOMAN, 589 -DNO_SHAREDOCS, and -DNO_LPR. 590 59120020831: 592 gcc has been upgraded to 3.2. It is not all binary compatible 593 with earlier versions of gcc for c++ programs. All c++ 594 programs and libraries need to be recompiled. 595 596 Also, if you encounter g++ issues, rm /usr/include/g++/* before 597 doing an installworld to make sure that stale files are removed. 598 59920020827: 600 Our /etc/termcap now has all the entries from the XFree86 xterm 601 almost unchanged. This means xterm now supports color by default. 602 If you used TERM=xterm-color in the past you now should use 603 TERM=xterm. (xterm-color will lead to benign warnings). 604 60520020815: 606 A "bug" in gcc(1) that was hiding warning in system headers was 607 fixed. It's probably time to add -DNO_WERROR to your make line 608 again. 609 61020020729: 611 COPY is being deprecated. The 20010530 change was reverted, as 612 it causes far more pain than was expected, and to always compare 613 before installing, please use INSTALL="install -C" again. The 614 -C option is now silently ignored when used with the -d option. 615 61620020702: 617 Problems with libc_r clients like KDE and GNOME have been resolved. 618 There are still some minor problems with some signals but the 619 system is stable enough for general use again. SMP is less so than UP 620 but each can successfully complete multiple buildworlds. 621 Libkvm needs to be recompiled due to KSE. 622 62320020701: 624 Now would be a bad time to upgrade. Something in or near the 625 KSE commit totally broke programs using libc_r like KDE and 626 GNOME. 627 62820020511: 629 The k5su utility installed as part of Kerberos 5 is no longer 630 installed with the set-user-ID bit set by default. Add 631 ENABLE_SUID_K5SU=yes to /etc/make.conf to have it installed 632 with the set-user-ID bit set. 633 63420020510: 635 Gcc 3.1 debugging format (cc -g) has changed from STABS to DWARF2. 636 Unfortunately our native GDB (at version 4.18) does not understand 637 the DWARF2 debugging format. Thus you must use `gcc -gstabs+' to 638 generated debugging information for our native GDB. 639 64020020510: 641 Due to the way CVS works, it may not properly update src/contrib/gcc 642 to the 3.1 sources. The easiest fix is to `rm -rf' src/contrib/gcc 643 and then do a cvs update. 644 64520020421: 646 When exec'ing set[ug]id executables, the kernel now ensures that the 647 stdio file descriptors (0..2) are open. See FreeBSD-SA-02:23.stdio. 648 64920020404: 650 New sendmail startup scripts have been installed to make it 651 easier to use alternative MTAs with FreeBSD. Setting the rc.conf 652 variable sendmail_enable to "NO" no longer prevents any sendmail 653 daemons from starting. Instead, either set sendmail_enable to 654 "NONE" or change mta_start_script to a script for starting 655 an alternative MTA. Setting mta_start_script to "" will 656 also prevent any MTA from being started at boot. 657 65820020403: 659 UCONSOLE is no longer a valid kernel option. 660 66120020315: 662 FreeBSD 5.0 DP-1 was basically branched today. 663 66420020225: 665 Warnings are now errors in the kernel. Unless you are a developer, 666 you should add -DNO_WERROR to your make line. 667 66820020217: 669 sendmail 8.12.2 has been imported. The sendmail binary is no 670 longer a set-user-ID root binary and the infrastructure to support 671 command line mail submission has changed. Be sure to run 672 mergemaster (especially for updating /etc/rc, /etc/defaults/rc.conf, 673 and /etc/mail) and read /etc/mail/README for more details. 674 675 Due to the import of sendmail 8.12.2, a new user and group are 676 required in order for sendmail to run as a set-group-ID 677 binary. A 'make installworld' will use the new user and group 678 to set the owner and group of /var/spool/clientmqueue and will 679 fail if the new user and group do not exist. The 'smmsp' user 680 and group must be merged from src/etc/group and 681 src/etc/master.passwd before using 'make installworld'. 682 'mergemaster -p' will do this. You may need to install 683 mergemaster before this will work if you are updating from a 684 very old version of current. The updating recipe has changed 685 as of this date. 686 68720020112: 688 The preferred configuration method for PAM is now /etc/pam.d/ 689 rather than /etc/pam.conf. If you have an unmodified 690 pam.conf, just delete it after your next mergemaster run. If 691 you have local modifications, you can use 692 /usr/src/etc/pam.d/convert.pl to incorporate them into your 693 /etc/pam.d. 694 695 Please see the following url for more details: 696http://www.freebsd.org/cgi/mid.cgi?db=mid&id=<xzp6667fyoa.fsf@flood.ping.uio.no> 69720011229: 698 If anyone here is already using the new rc.conf(5) variable 699 networkfs_types, please note that it has changed 700http://www.freebsd.org/cgi/mid.cgi?db=mid&id=<9744.1009655556@axl.seasidesoftware.co.za> 701 70220011220: 703 sys/i4b/driver/i4b_ispppsubr.c has been retired. This file 704 started out its life in the ISDN4BSD project as an offspring 705 from sys/net/if_spppsubr.c, which eventually got a life of its 706 own. All the accumulated features and bug fixes of the i4b 707 version have now been merged back into the base system's 708 version now. The only user-visible change resulting from this 709 is that i4b's sppp(4) interfaces are to be managed with 710 spppcontrol(8) again, since ispppcontrol(8) has been retired 711 as well. (There has never been rc file support for 712 ispppcontrol in -current, but only in -stable. That will be 713 reverted by the time the changes are MFCed.) 714 71520011215: 716 The fdc(4) driver has been updated and now automatically 717 recognizes media in `standard' formats (like 1440 KB and 718 720 KB for a 3.5" high-density drive) when accessing the 719 default device node (e. g. /dev/fd0). The old variety of 720 floppy device nodes /dev/fd*.* is no longer present by 721 default, devices can be created (in DEVFS) on demand. They 722 will need to be customized then for `odd' densities using 723 fdcontrol(8). 724 72520011209: 726 The bugs in procfs' debugging support code have been fixed, 727 and truss(1) now works again. 728 72920011207: 730 Daily security checks have been split out to use the periodic(8) 731 scripts. Some change in configuration may be necessary. Please 732 see 733http://www.freebsd.org/cgi/mid.cgi?db=mid&id=<20011207155805.R8975@blossom.cjclark.org> 734 for details. 735 73620011204: 737 sos added VCD/SVCD support to ata driver and that needs the 738 kernel and burncd to be in sync. 739 74020011203: 741 The procfs pseudo-filesystem has now been converted to use the 742 pseudofs framework. If you have 'options PROCFS' in your 743 kernel config, you'll need to add 'options PSEUDOFS' if it's 744 not there already. 745 746 This change temporarily breaks truss(1); use ktrace(1) instead 747 until the issue has been resolved. 748 74920011202: 750 A security hole in OpenSSH involving `UseLogin yes' has been 751 patched. 752 75320011126: 754 You need to remove /usr/obj/.../usr.bin/tip before rebuilding 755 after this date. You need to do this only once. 756 75720011103: 758 Most of the awk issues have been resolved. Some rough 759 edges may be left, but for the most part things should be 760 back to "normal." For CURRENT's usual definition of "normal." 761 76220011030: 763 Awk has been upgraded to the one true awk from bell labs. Expect 764 choppy waves in the upgrade process. 765 76620011030: 767 The asr driver problem has been resolved. 768 76920011027: 770 Due to changes in other parts of the system, the asr driver 771 now causes the system to panic on boot. Do not use it pending 772 correction. Comment it out of any kernel config file that you 773 try to use from this date forward. 774 77520011025: 776 When crossbuilding, use TARGET=xxx where you used to use 777 MACHINE=xxx. You don't need to set TARGET_ARCH and TARGET, 778 unless you are changing both of them. To cross build pc98 on 779 an alpha, for example, you need to set TARGET=pc98 and 780 TARGET_ARCH=i386. 781 78220011001: 783 The kernel interface that burncd depends on has changed. 784 You must recompile both the kernel and userland applications 785 at the same time. 786 78720010929: 788 When crossbuilding, please set TARGET_ARCH rather than 789 MACHINE_ARCH to indicate the target. In the future, one will 790 set TARGET_MACHINE where you set MACHINE now. At the moment, 791 setting MACHINE alone for same MACHINE_ARCH machines works 792 (eg, you can build pc98 on an i386 machine and vice versa). 793 79420010927: 795 Some weird problems result from using ACPI on some machines. 796 To disable ACPI you can add 797 hint.acpi.0.disabled="1" 798 to /boot/loader.conf (or by putting set X=Y at the boot 799 loader "ok" prompt). 800 801 Alternatively, you can remove it from /boot/kernel/acpi.ko 802 or use the MODULES_OVERRIDE function in your kernel config 803 file and not list acpi in that list. 804 80520010924: 806 The buildworld has been fixed. You may need to install 807 the 4.x compatibility libraries for some old binaries 808 to work. Add COMPAT4X=true to your /etc/make.conf to 809 get them installed on every installworld, or execute the 810 following to get them installed only once: 811 cd src/lib/compat/compat4x.<arch> 812 make all install 813 You will see ``__stdoutp undefined'' until you do this. 814 81520010919: 816 There's a bug in the world build process. The cross-tools 817 are build with the NEW headers, but the OLD libc.a. This 818 leads to all kinds of problems with the new libc. A temporary 819 workaround is to add 820 CFLAGS="-O -pipe -D_OLD_STDIO" 821 before building world when upgrading from 4.x to current. This 822 can be removed afterwards. 823 824 A proper fix to the buildworld target is needed. 825 82620010918: 827 Peter has committed his new kthread nfs client/server code. 828 NFS may be unstable after this date. 829 83020010912: 831 KSE has hit the tree. Lots of things are now different in 832 the kernel. While a few problems were introduced in the 833 initial commit, most of the major ones have been found and 834 corrected. 835 83620010901: 837 In OLDCARD, CardBus bridges appear to be stable. The work 838 arounds described in the 20010604 entry are now no longer 839 necessary and will be ignored. Most insert/remove problems 840 have been rectified around this date. 841 84220010823: 843 named now runs as user bind and group bind rather than as 844 root. If named_enable is set to YES in /etc/rc.conf, ensure 845 that user bind is available in /etc/passwd (using vipw(8)) 846 and that group bind is available in /etc/group. Also make 847 sure that user or group bind has read (and not write) 848 permission for your name server configuration and that it 849 has read and write permission for your slave zone files and 850 directory. 851 852 If you wish to continue to run named as root (a less secure 853 alternative), add a line to /etc/rc.conf saying 854 855 named_flags= 856 85720010709: 858 The PAM libraries have had an API upgrade that is beyond 859 the ability of the shared library major number to handle. 860 It is manifested by PAM-using ports dumping core. The 861 solution is to rebuild those ports. 862 86320010628: 864 The kernel compile module has moved from src/sys/compile/FOO 865 to src/sys/${MACHINE}/compile/FOO. 866 86720010625: 868 The pccard modem issue from 20010613 has been corrected. 869 OLDCARD support is still a little weak in -current. slot 1 is 870 known not to work on some TI based cardbus bridges. Some 871 cardbus bridges do not properly detect insert/removal events. 872 IRQ configuration needs more safety belts. 873 87420010617: 875 Softupdates problems have been corrected. 876 87720010614: 878 Peter ripped out the linkerset support. You must, as always, 879 rerun config after you cvsup if you are using the traditional 880 kernel building methods. 881 88220010613: 883 pccard modems may not work with current after 20010604 date. Some 884 do, others result in panics. *MAKE*SURE* that you update your 885 config and /etc/rc.conf ala the 20010604 entry, or you will have 886 problems (this issue will be fixed, it just hasn't been yet). 887 88820010613: 889 SOFTUPDATES seem to be broken since the middle of May or so. Do not 890 use them in current. You can disable softupdates on all mounted 891 partitions, or remove SOFTUPDATES the kernel config file. 892 89320010612: 894 After Peter's commits to the hints code, people have been noticing 895 that certain devices are attached (or try to) twice. This is due 896 to having both static hints as well as a /boot/device.hints. To 897 work around this issue, please use only one or the other mechanism 898 until this bug is fixed. 899 900 Please note that a feature of config is that if you have config 901 file FOO and FOO.hints, it automatically adds FOO.hints to the 902 hints.c file, whether you want it to or not. 903 90420010610: 905 Locale names have changed to match other systems better. 906 90720010604: 908 pccard support for pci cards has been committed. You must change 909 your /etc/pccard.conf irq lines. It must match the irq used by 910 pcic device. Interrupt storms may result if you fail to do this. 911 Interrupt storms look a lot like a hang. 912 913 You must also install a new pccardd, otherwise you will get an 914 interrupt storm at card reset time (just after it tells you what 915 it is). 916 917 pccardd_flags="-I" is necessary for the time being. It tells pccardd 918 not to ask the kernel if the interrupt is really free or not before 919 using it. You can either change the /etc/pccard.conf irq lines to 920 match pcic, or add "-i X" to the pccardd_flags. 921 92220010530: 923 INSTALL=install -C is being deprecated. If you want to do this, 924 use COPY=-C instead. The former method will be supported for only 925 a limited time. If you see 926 927install: warning: the -d and -C options may not be specified together 928 929 in your makeworld, then you need to migrate towards using 930 COPY=-C. 931 93220010525: 933 It appears that vm is now stable enough to use again. However, 934 there may be other problems, so caution is still urged. alpha 935 definitely is in bad shape. 936 93720010521: 938 Minor repo damage has happened. This may cause problems 939 with cvsup of ports. If you get errors, please see 940 http://www.FreeBSD.org/cgi/query-pr.cgi?pr=27495 941 at the bottom for details on a workaround. The error message 942 is 943Updater failed: Cannot delete "/usr/ports/www/jakarta-tomcat/files": Directory not empty 944 94520010520: 946 Vm and/or swapping are busted on -current. Please be patient. 947 94820010519: 949 pccard has had much reorganizational work done to it over 950 the past few days. Everything should still work, but if 951 not, please contact imp@freebsd.org. 952 95320010517: 954 ata ioctl changed. Make sure to recompile both kernel and 955 userland at the same time. 956 95720010517: 958 New ncurses imported. 959 96020010512: 961 DEVFS is now opt out, not opt in. Barring major problems, this 962 will be the only way to go starting July 1. 963 96420010504: 965 OpenSSH has been updated to 2.9. Some defaults are different, 966 including RhostsRSAAuthentication, which changes from yes to no. 967 96820010502: 969 Perl breakage in 20010501 was corrected at 14:18:33 PDT. 970 97120010501: 972 Building perl was broken at 02:25:25 PDT. 973 97420010430: 975 The bug in 20010429 was corrected at 07:35:37 PDT. It is safe to 976 go back in the water. 977 97820010429: 979 A bad bug was committed at 04:48:42 PDT. Don't use kernels after 980 this date, but before the correction date. 981 98220010423: 983 old fsck and new kernel interactions appear to have been fixed. 984 98520010411: 986 fsck and the kernel were changed to handle some optimizations 987 to directory layout. This breaks backward compatibility. 988 Update only if you understand that you must not use the old 989 fsck with the new kernel ever. 990 99120010330: 992 fsck has changed the meaning of the pass column in /etc/fstab. 993 Please see the cvs commit to fsck.8 or the fsck.8 man page for 994 details. It is unclear if changes to /etc/fstab are necessary. 995 99620010319: 997 portmap had changed name to rpcbind for maximum POLA in your 998 current world. /etc/hosts.{allow,deny} needs changes. nfs and 999 other rpc based programs that rely on portmapper will not work 1000 without updates to /etc/hosts.{allow,deny} and /etc/netconfig. 1001 100220010315: 1003 ata subsystem changes. ATA_ENABLE_ATAPI_DMA, ATA_ENABLE_WC 1004 and ATA_ENABLE_TAGS are no longer kernel options. They have 1005 been replaced by tunables. See ata.4 for details. 1006 100720010312: 1008 The fxp driver was converted to use miibus. If you compile 1009 fxp into your kernel statically, you will need to add miibus. 1010 101120010312: 1012 The wi device now defaults to BSS (infrastructure) mode 1013 instead of ad-hoc. 1014 101520010310: 1016 /dev/urandom should be a symbolic link to /dev/random now. 1017 Users of current not using DEVFS need to run MAKEDEV std. 1018 ssh might not work if you don't. 1019 102020010303: 1021 The ed driver has been updated. It now allows mii attachments, 1022 which means that you must include the miibus in your kernel if 1023 you use the ed driver. 1024 102520010220: 1026 The problems with libc have been corrected. It is now mostly 1027 safe to go back into the water. 1028 102920010211: 1030 The size of FILE was changed. This breaks upgrading. If 1031 you must upgrade, be prepared for pain. It also breaks almost 1032 all binaries that you've compiled on -current. You are warned 1033 that before upgrading would be a good time to do a level 0 1034 dump of your system. No, really, I mean it this time. 1035 1036 To get to the new system, you'll need to use the following 1037 workaround. Hopefully this can be sorted out so that we 1038 don't have to move this to the updating section. 1039 1040 To get around the installworld problem, do: 1041 # cd /usr/src/usr.bin/sed 1042 # make install 1043 # cd /usr/src 1044 # make installworld 1045 If that doesn't work, then try: 1046 # make -k installworld 1047 # make installworld 1048 104920010207: 1050 DEVFS is now the default. If you use vinum, make sure that you 1051 do not include devfs in your kernel as problems result. 1052 105320010205: 1054 FFS_ROOT and CD9660_ROOT have been removed or deprecated. 1055 Remove them from your config. 1056 105720010122: 1058 ****************************** WARNING ****************************** 1059 buildkernel has been changed slightly 1060 ****************************** WARNING ****************************** 1061 KERNCONF replaces the variable KERNEL for buildkernel. You 1062 should update your scripts and make.conf accordingly. 1063 106420010119: 1065 config has changed to allow DEV_FOO as a replacement for NFOO. 1066 This requires a new config to build correctly. 1067 106820010116: 1069 The kernel option I386_CPU is now mutually exclusive with the 1070 other cpu types. If you have an i386 system, be sure that it 1071 only had this line. Remove it for all other configurations. 1072 107320010110: 1074 Changes to the kernel require it and burncd be in sync. 1075 107620010102: 1077 Everyone who has hw.sndunit set to something in 1078 /etc/sysctl.conf, it is now hw.snd.unit. 1079 108020010101: 1081 ex and vi were broken by some changes to sys/queue.h. If you 1082 have a bad vi, you will see make buildworld fail with a core 1083 dump while building termcap. You can work around this problem 1084 by adding -k to your make buildworld. This will cause the 1085 build to complete and install a new vi. Once that's done, you 1086 can rebuild again without the -k to pick up anything that 1087 might have been ignored by the -k option. 1088 1089 Others have suggested that you can just rebuild libc if your 1090 vi/ex is dynamically linked, but I've not received any reports 1091 of this working. 1092 109320001228: 1094 There have been some changes to libcrypt in -current. The 1095 libscrypt/libdescrypt symlink silliness is gone and the installed 1096 libcrypt is fully functional. Be aware of this. 1097 109820001218: 1099 Linksys Fast Ethernet PCCARD cards supported by the ed driver 1100 now require the addition of flag 0x80000 to their config line 1101 in pccard.conf(5). This flag is not optional. These Linksys 1102 cards will not be recognized without it. 1103 110420001205: 1105 Important new FreeBSD-version stuff: PAM support has been worked 1106 in, partially from the "Unix" OpenSSH version. This requires 1107 adding the following in pam.conf: 1108 1109 sshd auth sufficient pam_skey.so 1110 sshd auth required pam_unix.so try_first_pass 1111 sshd session required pam_permit.so 1112 111320001031: 1114 cvs updated to 1.11. 1115 111620001020: 1117 The random device needs more entropy, so you need to make sure 1118 that you've run mergemaster to get a /etc/rc which will seed 1119 /dev/random. If you don't and the system hangs after ldconfig, 1120 then banging on the keyboard randomly until it unhangs is one 1121 workaround. 1122 112320001010: 1124 ****************************** WARNING ****************************** 1125 Sendmail has been updated. 1126 ****************************** WARNING ****************************** 1127 o mail.local(8) is no longer installed as a set-user-id binary. 1128 o sendmail(8) is now built with STARTTLS support unless NO_OPENSSL 1129 is set. 1130 o The default /etc/mail/sendmail.cf disables the SMTP EXPN and VRFY 1131 commands. 1132 o Now using sendmail's version of vacation(1). 1133 o The sendmail cf building tools (contrib/sendmail/cf) are installed 1134 in /usr/share/sendmail/cf. 1135 o sendmail.cw changed to local-host-names 1136 1137 More details can be found at 1138 http://people.freebsd.org/~imp/UPDATING/sendmail-20001010 1139 114020001009: 1141 The ports tree's new layout is in place. Be sure to update 1142 your entire ports tree, or you will have problems. 1143 114420001006: 1145 The perl build procedure no longer installs miniperl, nor uses 1146 the installed miniperl. It is recommended that you delete 1147 /usr/bin/miniperl. 1148 114920001005: 1150 This weekend the ports tree will be updated to a new layout. 1151 It will be in an inconsistent state until noted in the UPDATING 1152 file, or with asami-san's message to the relevant mailing 1153 lists. With this new layout, you'll need to update the whole 1154 tree for anything to work. 1155 115620000928: 1157 There was a change in the passwd format. Need more information. 1158 115920000916: 1160 /boot/kernel/kernel.ko -> /boot/kernel/kernel change has taken 1161 place. Please update boot loader (not the boot blocks) at the 1162 same time as your kernel. 1163 116420000914: 1165 The new pmtimer device is necessary for laptops. Failure to 1166 include the device will cause suspended laptops losing time 1167 when they resume. Include 1168 device pmtimer 1169 in your config file and 1170 hint.pmtimer.0.at="isa" 1171 to your /boot/device.hints file. 1172 117320000911: 1174 The random device has been turned into a (pseudo-)device, 1175 rather than an option. The supplied kernel config files have 1176 been updated. You will need to do something similar in your 1177 own kernel config file. 1178 Remove: 1179 options RANDOMDEV 1180 Add: 1181 device random 1182 If you prefer to load the loadable module, you need to do 1183 nothing. 1184 118520000909: 1186 The random device module has been renamed from randomdev.ko to 1187 random.ko. You will need to edit your /boot/loader.conf to 1188 reflect this if you load this module at boot time. 1189 The line should read: 1190 random_load="YES" 1191 119220000907: 1193 The SMPNG commit has happened. It should work, but if it 1194 doesn't, fallback to the PRE_SMPNG CVS tag. There are likely 1195 to be a variety of minor issues. Please see 20000905 to make 1196 sure you don't have model loading problems which might at 1197 first blush appear related to SMP. 1198 119920000906: 1200 nsswitch has been imported from NetBSD. Among other things, 1201 this means that /etc/host.conf is no longer used. See 1202 nsswitch.conf(5) instead. Note that at boot time rc.network 1203 will attempt to produce a new nsswitch.conf file for you if you 1204 don't have one, and you have host.conf. 1205 120620000905: 1207 The ucred structure changed size. This breaks the interface 1208 that mountd uses. Trying to use an older mountd with a newer 1209 kernel guarantees a panic. This means that you need to use 1210 kernels newer than today only with matching mountd, but you 1211 needed to do that anyway with the boot loader changes. 1212 121320000905: 1214 The boot loader has been updated. The new default kernel is 1215 now /boot/kernel/kernel.ko. The new default module location 1216 is /boot/kernel. 1217 1218 You *MUST* upgrade your boot loader and kernel at the same time. 1219 The easiest way to do this is to do the buildworld/buildkernel/ 1220 installkernel/installworld dance. 1221 1222 Furthermore, you are urged to delete your old /modules directory 1223 before booting the new kernel, since kldload will find stale 1224 modules in that directory instead of finding them in the correct 1225 path, /boot/kernel. The most common complaint that this cures 1226 is that the linux module crashes your machine after the update. 1227 1228 if [ ! -d /boot/kernel.old ]; then 1229 mv /modules.old /boot/kernel.old 1230 chflags noschg /kernel.old 1231 mv /kernel.old /boot/kernel.old/kernel.ko 1232 chflags schg /boot/kernel.old/kernel.ko 1233 fi 1234 123520000904: 1236 A new issue with the sendmail upgrade has come to light. 1237 /etc/aliases has moved to /etc/mail/aliases. Mergemaster will 1238 incorrectly install the default aliases in /etc/mail rather than 1239 move the old one from /etc. So you'll need to manually move the 1240 file, create a symbolic link, remove the old /etc/aliases.db and 1241 run newaliases. For safety sake, you should stop sendmail 1242 while doing this and run the upgrade when locally sourced email 1243 is not likely to be generated. 1244 124520000825: 1246 /boot/device.hints is now required for installkernel to 1247 succeed. You should copy GENERIC.hints for your architecture 1248 into /boot/device.hints. If and only if you compile hints 1249 into your kernel, then this file may be empty. Please note, 1250 if you have an empty or missing /boot/device.hints file and 1251 you neglected to compile hints into your kernel, no boot 1252 messages will appear after the boot loader tries to start the 1253 kernel. 1254 125520000821: 1256 If you do NOT have ``options RANDOMDEV'' in your kernel and 1257 you DO want the random device then add randomdev_load="YES" to 1258 /boot/loader.conf. 1259 126020000812: 1261 suidperl is now always built and installed on the system, but 1262 with permissions of 511. If you have applications that use 1263 this program, you are now required to add ENABLE_SUIDPERL=true 1264 to /etc/make.conf. If you forget to do this, 1265 chmod 4511 /usr/bin/suidperl 1266 will fix this until the next build. 1267 126820000812: 1269 sendmail has been updated from 8.9.3 to 8.11.0. Some of the more 1270 visible changes that may immediately affect your configuration 1271 include: 1272 - New default file locations from src/contrib/sendmail/cf/README 1273 - newaliases limited to root and trusted users 1274 - MSA port (587) turned on by default 1275 - New queue file naming system so can't go from 8.11 -> 8.9 1276 - FEATURE(`rbl') renamed to FEATURE(`dnsbl') 1277 - FEATURE(`nullclient') is more full featured 1278 - FEATURE(`nouucp') requires an argument: `reject' or `nospecial' 1279 - mail.local FreeBSD-only -b option changed to -B 1280 - See src/contrib/sendmail/RELEASE_NOTES for more info 1281 128220000810: 1283 suidperl (aka sperl) is no longer build by default. You must 1284 specifically define BUILD_SUIDPERL to "true" for it to be build. 1285 Furthermore, we recommend that you remove /usr/bin/sperl* and 1286 /usr/bin/suidperl files from your system unless you have a 1287 specific use for it. 1288 128920000729: 1290 Networking defaults have been tightened. Anybody upgrading 1291 /etc/defaults/rc.conf needs to add the following lines to 1292 /etc/rc.conf if they want to have the same setup 1293 afterwards (unless the variables already are set, of course): 1294 # Enable network daemons for user convenience. 1295 inetd_enable="YES" 1296 portmap_enable="YES" 1297 sendmail_enable="YES" 1298 129920000728: 1300 If you have null_load="YES" in your /boot/loader.conf, you 1301 will need to change that to nullfs_load="YES". 1302 130320000728: 1304 The "installkernel" target has changed slightly. Now even if 1305 you override KERNEL e.g. 'make installkernel KERNEL=MYKERNEL' 1306 it will install the MYKERNEL file (built with the buildkernel 1307 target) as /kernel rather than /MYKERNEL. Those who have 1308 updated their /boot/loader.conf files to point to /MYKERNEL 1309 should remove that entry or perform manual rename of /kernel 1310 to /MYKERNEL. 1311 131220000711: 1313 If you use CVSUP or CTM to get CVS trees, AND you used to get 1314 the old crypto files from internat.freebsd.org AND you check 1315 out files from the CVS tree with the cvs command, please read 1316 http://people.freebsd.org/~imp/internat.txt 1317 for details on potential problems that you might have and how 1318 to get around them. 1319 1320 If you are merely a mirror, or don't answer yes to each of the 1321 clauses above, you needn't worry. 1322 132320000711: 1324 /etc/security has been updated to print the inode number of 1325 setuid programs that have changed. You will see a large spike 1326 in the number of changed programs the first time when you run 1327 mergemaster to get a new /etc/security. 1328 132920000710: 1330 /dev/random now has good entropy collection (from the keyboard 1331 and sysmouse drivers). Please ensure that either `options 1332 RANDOMDEV' is present in your kernel config file or that 1333 `randomdev_load="YES"' is in your /boot/loader.conf. If you do 1334 not have the /dev/random driver, OpenSSL (and consequently 1335 lots of crypto tools (like SSH)) will fail with strange 1336 errors. (see below, 20000624). 1337 1338 FreeBSD-current is safe again to run Crypto. 1339 134020000709: 1341 phk made the malloc default options AJ. This may slow things 1342 down and uncover other latent bugs in the code. If you need to 1343 run at full speed, you can disable this by doing the following: 1344 ln -s aj /etc/malloc.conf 1345 134620000706: 1347 libftpio's version was accidentally bumped a few days ago. This 1348 has been corrected. You may need to remove /usr/lib/libftpio.so.6 1349 before doing your next buildworld/installworld pair. It certainly 1350 won't hurt to remove it before the update procedure. It will 1351 break fetch until a new one is built, but ftp can be used in the 1352 interim if needed. 1353 135420000705: 1355 The crypto packages have changed for the cvsup. This has been done 1356 in a backward compatible way, but the old packages will go away at 1357 some point in the future. Look at /usr/share/examples/cvsup for 1358 details. 1359 136020000704: 1361 With the new sys/modules/sound/drivers/*, you will need to 1362 set SYSDIR until you do an installworld after July 7th. 1363 136420000704: 1365 rc.shutdown and rc will now call the rc.d scripts with start 1366 or stop. This may cause some harmless warnings from older 1367 rc.d scripts that haven't been updated. 1368 136920000630: 1370 The libfetch based version of fetch has gone into the tree. 1371 Minor problems may result on some of the less popular sites, 1372 which should be reported to des@freebsd.org. 1373 137420000625: 1375 From approximately this date forward, one must have the crypto 1376 system installed in order to build the system and kernel. 1377 While not technically strictly true, one should treat it as 1378 required and grab the crypto bits. If you are grabbing CVS 1379 trees, src-all and cvs-crypto should be treated as if they 1380 were required. You should check with the latest collections 1381 to make sure that these haven't changed. 1382 138320000624: 1384 Mark Murray just committed the first parts of a cleanup of 1385 /dev/zero, et al. This is also cleaning up /dev/random. 1386 The entropy is disconnected, so DO NOT USE VERSIONS OF FREEBSD 1387 -CURRENT FROM THIS POINT to 2000710 for cryptographic services 1388 until Mark can merge in the fixes to this work in progress. 1389 openssh and openssl should not be used to generate keys from this 1390 date to the completion of the work. 1391 1392 If you must operate at this reduced level of security, add ' 1393 options RANDOMDEV' to your kernel or modload the randomdev 1394 module. You may also need to copy a new MAKEDEV to /dev and 1395 recreate the random and urandom devices. 1396 139720000622: 1398 The license on the softupdates is now a standard 2 clause 1399 BSD license. You may need to remove your symbolic links 1400 that used to be required when updating. 1401 140220000621: 1403 Scott Flatman <sf@aracnet.com> sent in a decent write-up on 1404 the config file update procedure. 1405 http://people.freebsd.org/~imp/config-upd.html 1406 NOTE: LINT is gone. It has been replaced with NOTES. NOTES 1407 isn't buildable. However, you can generate a LINT file: 1408 cd /sys/<ARCH>/conf && make LINT 1409 141020000620: 1411 Binutils 2.10 have hit the tree, or will shortly. As soon 1412 as they do, the problem noted in 20000522 will be resolved and 1413 that workaround will no longer be required. 1414 141520000615: 1416 phk removed the compatibility creation of wd devices in the 1417 ad driver. If you haven't done so already, you must update 1418 your fstab, etc to use the ad devices instead of the wd 1419 devices. 1420 1421 In addition, you'll need to update your boot blocks to a 1422 more modern version, if you haven't already done so. Modern 1423 here means 4.0 release or newer (although older releases 1424 may work). 1425 142620000612: 1427 Peter took an axe to config(8). Be sure that you read his mail 1428 on the topic before even thinking about updating. You will 1429 need to create a /boot/device.hints or add a hints directive 1430 to your config file to compile them in statically. The format 1431 of the config file has changed as well. Please see GENERIC or 1432 NEWCARD for examples of the new format. 1433 1434 Indirectly, this also breaks USERCONFIG. Unless a newer entry 1435 says that it has been fixed, assume that must use the hints mechanism 1436 in the loader if you need to use a machine with very old ISA cards 1437 in it. 1438 143920000522: 1440 A new set of binutils went into the tree today. Anybody 1441 building a kernel after this point is advised that they need 1442 to rebuild their binutils (or better yet do a 1443 buildworld/installworld) before building a new kernel. 1444 1445 Due to bugs in binutils, using malloc options (eg /etc/malloc.conf 1446 or MALLOC_OPTIONS env var) J will cause ld to dump core. It 1447 is recommended that you don't set this option until the problem 1448 is resolved. 1449 145020000513: 1451 The ethernet drivers were all updated to clean up the BPF handling. 1452 145320000510: 1454 The problems with boot blocks on the alphas have been corrected. 1455 This will require some care in updating alphas. A new libstand 1456 is requires for the boot blocks to build properly. 1457 145820000503: 1459 Recompile all kld modules. Proper version dependency info 1460 is now available. 1461 146220000502: 1463 Modules have been disconnected from the buildworld tree and 1464 connected to the kernel building instead. 1465 146620000427: 1467 You may need to build gperf 1468 cd /usr/src/gnu/usr.bin/gperf && make depend all install 1469 when upgrading from 4.0 -> current. The build system now uses 1470 an option only in -current. 1471 147220000417: 1473 The method that we brand ELF binaries has changed to be more 1474 acceptable to the binutils maintainers. You will need to 1475 rebrand your ELF binaries that aren't native. One problem 1476 binary is the Linux ldconfig. After your make world, but 1477 before you reboot, you'll need to issue: 1478 brandelf -t Linux /compat/linux/sbin/ldconfig 1479 if you have Linux compatibility enabled on your machine. 1480 148120000320: 1482 If you have really bad/marginal IDE drives, you may find they 1483 don't work well. Use pio mode instead. The easiest way to 1484 cope if you have a problem combination is to add: 1485 /sbin/sysctl hw.ata.ata_dma=0 1486 to the start of /etc/rc.conf. 1487 148820000319: 1489 The ISA and PCI compatibility shims have been connected to the 1490 options COMPAT_OLDISA and COMPAT_OLDPCI. If you are using old 1491 style PCI or ISA drivers (i.e. tx, voxware, etc.) you must 1492 include the appropriate option in your kernel config. Drivers 1493 using the shims should be updated or they won't ship with 1494 5.0-RELEASE, targeted for 2001. 1495 149620000318: 1497 We've entered the traditional post release dumping party. 1498 Large kernel changes are being committed and are in the 1499 works. It is important to keep the systems' klds and kernel 1500 in sync as kernel interfaces and structures are changing. 1501 Before reporting kernel panics, make sure that all modules 1502 that you are loading are up to date. 1503 150420000315: 1505 If you are upgrading from an older version of FreeBSD, you 1506 need to update your boot blocks as well. 'disklabel -B ad0' 1507 will do the trick. This isn't critical until you remove your 1508 wd device entries in /dev, at which point your system will not 1509 boot. 1510 151120000315: 1512 4.0 RELEASE shipped. Please see the 4.0 UPDATING file for how 1513 to upgrade to 4.0 from 3.x. 1514 1515COMMON ITEMS: 1516 1517 General Notes 1518 ------------- 1519 Avoid using make -j when upgrading. From time to time in the 1520 past there have been problems using -j with buildworld and/or 1521 installworld. This is especially true when upgrading between 1522 "distant" versions (eg one that cross a major release boundary 1523 or several minor releases, or when several months have passed 1524 on the -current branch). 1525 1526 Sometimes, obscure build problems are the result of environment 1527 poisoning. This can happen because the make utility reads its 1528 environment when searching for values for global variables. 1529 To run your build attempts in an "environmental clean room", 1530 prefix all make commands with 'env -i '. See the env(1) manual 1531 page for more details. 1532 1533 To build a kernel 1534 ----------------- 1535 If you are updating from a prior version of FreeBSD (even one just 1536 a few days old), you should follow this procedure. With a 1537 /usr/obj tree with a fresh buildworld, 1538 make -DALWAYS_CHECK_MAKE buildkernel KERNCONF=YOUR_KERNEL_HERE 1539 make -DALWAYS_CHECK_MAKE installkernel KERNCONF=YOUR_KERNEL_HERE 1540 1541 To just build a kernel when you know that it won't mess you up 1542 -------------------------------------------------------------- 1543 This assumes you are already running a 5.X system. Replace 1544 ${arch} with the architecture of your machine (e.g. "i386", 1545 "alpha", "amd64", "ia64", "pc98", "sparc64", etc). 1546 1547 cd src/sys/${arch}/conf 1548 config KERNEL_NAME_HERE 1549 cd ../compile/KERNEL_NAME_HERE 1550 make depend 1551 make 1552 make install 1553 1554 If this fails, go to the "To build a kernel" section. 1555 1556 To rebuild everything and install it on the current system. 1557 ----------------------------------------------------------- 1558 # Note: sometimes if you are running current you gotta do more than 1559 # is listed here if you are upgrading from a really old current. 1560 1561 <make sure you have good level 0 dumps> 1562 <maybe fix /etc/fstab> [7] 1563 make buildworld 1564 make buildkernel KERNCONF=YOUR_KERNEL_HERE 1565 make installkernel KERNCONF=YOUR_KERNEL_HERE 1566 [1] 1567 <reboot in single user> [3] 1568 /etc/rc.d/preseedrandom [10] 1569 mergemaster -p [5] 1570 make installworld 1571 mergemaster [4] 1572 <reboot> 1573 1574 1575 To cross-install current onto a separate partition 1576 -------------------------------------------------- 1577 # In this approach we use a separate partition to hold 1578 # current's root, 'usr', and 'var' directories. A partition 1579 # holding "/", "/usr" and "/var" should be about 2GB in 1580 # size. 1581 1582 <make sure you have good level 0 dumps> 1583 <boot into -stable> 1584 make buildworld 1585 <maybe newfs current's root partition> 1586 <mount current's root partition on directory ${CURRENT_ROOT}> 1587 make installworld DESTDIR=${CURRENT_ROOT} 1588 make buildkernel KERNCONF=YOUR_KERNEL_HERE 1589 cp /usr/src/sys/${ARCH}/conf/GENERIC.hints \ 1590 ${CURRENT_ROOT}/boot/device.hints # as needed 1591 make installkernel KERNCONF=YOUR_KERNEL_HERE DESTDIR=${CURRENT_ROOT} 1592 cd /usr/src/etc; make distribution DESTDIR=${CURRENT_ROOT} # if newfs'd 1593 cp /etc/fstab ${CURRENT_ROOT}/etc/fstab # if newfs'd 1594 <edit ${CURRENT_ROOT}/etc/fstab to mount "/" from the correct partition> 1595 <reboot into current> 1596 <do a "native" rebuild/install as described in the previous section> 1597 <maybe install compatibility libraries from /usr/src/lib/compat> 1598 <reboot> 1599 1600 1601 To upgrade in-place from 4.x-stable to current 1602 ---------------------------------------------- 1603 # 5.x uses more space than 4.x. Also, the location of kernel 1604 # modules has changed. If you are installing 5.0 onto a 4.x 1605 # system, you'll need about 30MB of free disk space on your / 1606 # partition. If you have less than this, you may encounter difficult 1607 # to back out of problems with this procedure. If /tmp is on 1608 # the / partition, you may want to completely remove all its content 1609 # before upgrading, as this can be a common source of shortage of 1610 # space on /. 1611 1612 <make sure you have good level 0 dumps> 1613 <maybe fix /etc/fstab> [7] 1614 make buildworld [9] 1615 make buildkernel KERNCONF=YOUR_KERNEL_HERE [8] 1616 cp sys/${MACHINE}/conf/GENERIC.hints /boot/device.hints [2] 1617 make installkernel KERNCONF=YOUR_KERNEL_HERE 1618 cd sys/boot ; make STRIP="" install [6] 1619 [1] 1620 <reboot in single user> [3] 1621 /usr/src/etc/rc.d/preseedrandom [10] 1622 mergemaster -p [5] 1623 rm -rf /usr/include/g++ 1624 make installworld 1625 mergemaster -i [4] 1626 <reboot> 1627 1628 Make sure that you've read the UPDATING file to understand the 1629 tweaks to various things you need. At this point in the life 1630 cycle of current, things change often and you are on your own 1631 to cope. The defaults can also change, so please read ALL of 1632 the UPDATING entries. 1633 1634 Also, if you are tracking -current, you must be subscribed to 1635 freebsd-current@freebsd.org. Make sure that before you update 1636 your sources that you have read and understood all the recent 1637 messages there. If in doubt, please track -stable which has 1638 much fewer pitfalls. 1639 1640 [1] If you have third party modules, such as vmware, you 1641 should disable them at this point so they don't crash your 1642 system on reboot. 1643 1644 [2] If you have legacy ISA devices, you may need to create 1645 your own device.hints to reflect your unique hardware 1646 configuration. 1647 1648 [3] From the bootblocks, boot -s, and then do 1649 fsck -p 1650 mount -u / 1651 mount -a 1652 cd /usr/src 1653 adjkerntz -i # if CMOS is wall time 1654 Also, when doing a major release upgrade, it is required that 1655 you boot into single user mode to do the installworld. 1656 For the 4.x -> 5.0 upgrade, you will also see many messages about 1657 needing to recompile your userland. These are harmless and can 1658 be ignored while you proceed to the next step. 1659 1660 [4] Note: This step is non-optional. Failure to do this step 1661 can result in a significant reduction in the functionality of the 1662 system. Attempting to do it by hand is not recommended and those 1663 that pursue this avenue should read this file carefully, as well 1664 as the archives of freebsd-current and freebsd-hackers mailing lists 1665 for potential gotchas. 1666 1667 [5] Usually this step is a noop. However, from time to time 1668 you may need to do this if you get unknown user in the following 1669 step. It never hurts to do it all the time. You may need to 1670 install a new mergemaster (cd src/usr.sbin/mergemaster && make 1671 install) after the buildworld before this step if you last updated 1672 from current before 20020224 or from -stable before 20020408. 1673 1674 [6] 4.x boot loader can be used to boot a 5.x system, however 1675 it is difficult to do that at best. If you wish to try, then 1676 you should interrupt the boot and at the ok prompt type: 1677 ok unload 1678 ok boot /boot/kernel/kernel 1679 If this fails to work, you must install a new boot loader as 1680 described here. 1681 1682 [7] Before you upgrade, please make sure that you are not using 1683 compatibility slices. These are device names of the form, on i386 1684 and other architectures that use MBR slicing, /dev/ad0a without the 1685 actual slice name. Chances are excellent that these will break. 1686 You generally must update these entries to use the post FreeBSD 1687 2.x form of /dev/ad0s1a. 1688 1689 [8] In order to have a kernel that can run the 4.x binaries 1690 needed to do an installworld, you must include the COMPAT_FREEBSD4 1691 option in your kernel. Failure to do so may leave you with a system 1692 that is hard to boot to recover. 1693 1694 [9] When checking out sources, you must include the -P flag to have 1695 cvs prune empty directories. Also, if CPUTYPE is defined in your 1696 /etc/make.conf, make sure to use the "?=" instead of the "=" assignment 1697 operator, so that buildworld can override the CPUTYPE if it needs to. 1698 In case you would like to avoid installing new packages of everything, 1699 you might want to uncomment the "COMPAT4X= YES" entry, so that 4.x 1700 compatibility libraries are build which should allow you to continue 1701 using your existing software for a while. 1702 1703 [10] In order to create temporary files, /dev/random must be 1704 initialized by feeding data into it. /etc/rc.d/preseedrandom 1705 takes care of this. 1706FORMAT: 1707 1708This file contains a list, in reverse chronological order, of major 1709breakages in tracking -current. Not all things will be listed here, 1710and it only starts on March 15, 2000. Updating files can found in 1711previous releases if your system is older than this. 1712 1713Copyright information: 1714 1715Copyright 1998, 2002 M. Warner Losh.
