These features attempt to detect 16102779Siedowse incorrect use of system primitives, and encourage loud failure 17102779Siedowse through extra sanity checking and fail stop semantics. They 18102779Siedowse also substantially impact system performance. If you want to 19102779Siedowse do performance measurement, benchmarking, and optimization, 20102779Siedowse you'll want to turn them off. This includes various WITNESS- 21102779Siedowse related kernel options, INVARIANTS, malloc debugging flags 22102779Siedowse in userland, and various verbose features in the kernel. Many 23102779Siedowse developers choose to disable these features on build machines 24102779Siedowse to maximize performance. 25102779Siedowse 26102779Siedowse20040819: 27102779Siedowse Netgraph changed its message format slightly to align the data 28102779Siedowse portion well on 64 bit machines. 29102779Siedowse Netgraph using utilities (e.g. ngctl, nghook, ppp, mpd, 30102779Siedowse pppoed, bluetooth, ATM) should be recompiled when a new kernel 31102779Siedowse is installed. 32102779Siedowse 33102779Siedowse20040817: 34110294Sume IPFW has been converted to use PFIL_HOOKS. This change is 35114749Sdwmalone transparent to userland and preserves the ipfw ABI. The ipfw 36114749Sdwmalone core packet inspection and filtering functions have not been 37110294Sume changed, only how ipfw is invoked is different. Note that 38102870Siedowse "option PFIL_HOOKS" is required to use IPFIREWALL compiled 39102870Siedowse into the kernel or as KLD. 40102779Siedowse 41102779Siedowse20040814: 42110294Sume The RANDOM_IP_ID option has been replaced by the sysctl 43102779Siedowse net.inet.ip.random_id. If you had RANDOM_IP_ID in your kernel then 44102779Siedowse you may want to add "net.inet.ip.random_id=1" to /etc/sysctl.conf. 45102779Siedowse 46102779Siedowse20040807: 47102779Siedowse The size of 'struct ifnet' has changed due to the addition of the 48110294Sume if_carp placeholder. All kernel modules implementing network 49102868Siedowse interfaces must be recompiled as a result. 50102779Siedowse 51102779Siedowse20040806: 52102779Siedowse Module loading has been fixed. Some older installations will 53102779Siedowse drop proper module_path initialization and modules will fail to 54102779Siedowse load properly. If you have a line in /boot/loader.rc that says: 55102779Siedowse "initialize drop", do (i386 only): 56102779Siedowse cp /usr/src/sys/boot/i386/loader/loader.rc /boot/loader.rc 57102779Siedowse chown root:wheel /boot/loader.rc 58102779Siedowse chmod 444 /boot/loader.rc 59102779Siedowse 60102779Siedowse20040802: 61102779Siedowse making /dev/(null|zero) into a module proved to be too unpopular, 62102779Siedowse so this bit has been revoked from the previous (20040801) entry. 63102779Siedowse 64102779Siedowse20040801: 65102779Siedowse The /dev/mem, /dev/io /dev/(null/zero) devices are now modules, 66102946Siedowse so you may wish to add them to your kernel config file. See 67102946Siedowse GENERIC for examples. 68102779Siedowse 69102779Siedowse20040728: 70102779Siedowse System compiler has been upgraded to GCC 3.4.2-pre. As with any major 71102779Siedowse compiler upgrade, there are several issues to be aware of. GCC 3.4.x 72102779Siedowse has broken C++ ABI compatibility with previous releases yet again 73102779Siedowse and users will have to rebuild all their C++ programs with the new 74102779Siedowse compiler. If you are getting run-time error such as 75114749Sdwmalone /libexec/ld-elf.so.1: Undefined symbol "_ZNSs20_S_empty_rep_storageE" 76114749Sdwmalone This entry does apply to you. 77114724Smbr 78122088Sfjoe A new unit-at-a-time optimization mode, which is default in this 79114724Smbr compiler release, is more aggressive in removing unused static 80122088Sfjoe symbols. This is the likely cause of 'make buildworld' breakages 81102779Siedowse with non-default CFLAGS where optimization level is set to -O2 82105950Speter or higher. 83102779Siedowse 84113685Sjhb With the upgrade of the system compiler, the kernel has been upgraded 85113685Sjhb to match the new system compiler. This makes it impossible to build 86102779Siedowse a new kernel with the old compiler. Upgrade your system via 87102779Siedowse make buildworld and make kernel (see below) to fix this problem. 88102779Siedowse 89102779Siedowse20040727: 90102779Siedowse The size of 'struct ifnet' has changed due to the addition of 91102779Siedowse the IFF_NEEDSGIANT flag (and what it implies). All kernel 92102779Siedowse modules implementing network interfaces must be recompiled as 93102779Siedowse a result. 94102779Siedowse 95105950Speter20040716: 96105950Speter The sound device drivers are renamed. `sound' is always required, 97105950Speter while `snd_*' should be configured accordingly to your hardware. 98105950Speter Refer to NOTES for the detail of the drivers. 99102779Siedowse 10020040710: 101 __FreeBSD_version bumped to 502122. 102 10320040710: 104 The console initialization on Alpha has been reworked and is now 105 identical to other platforms. This means that the hardcoding of 106 the serial console and the debug port has been removed. As such, 107 hints are now required for the sio(4) driver to become a console 108 or debug port. The NO_SIO option has been decommissioned because 109 of this. 110 11120040710: 112 A revamp of the debugging code in the kernel with some visible 113 changes beyond just the debugging experience: 114 o The DDB option is now specific to the DDB debugger backend 115 and should not be used any more for conditional compilation 116 of debugging code for when debugging is enabled. Use the KDB 117 option for this. 118 o The WITNESS_DDB, DDB_TRACE and DDB_UNATTENDED options have 119 been renamed to WITNESS_KDB, KDB_TRACE and KDB_UNATTENDED 120 respectively. This is in line with the first bullet. 121 o The remote GDB support has been untangled from DDB and needs 122 to be enabled separately now. Use the GDB option for this. 123 o The GDB_REMOTE_CHAT option has been removed. Support for this 124 homegrown feature is discontinued. The GDB remote protocol 125 supports console output and it makes sense to use that. 126 o The DDB_NOKLDSYM option has been removed. The DDB debugger 127 now supports both direct symbol table lookups as well as KLD 128 symbol lookups through the linker. 129 13020040708: 131 Bluetooth code has been marked as non-i386 specific. 132 __FreeBSD_version has been bumped to 502121 to mark this change. 133 13420040702: 135 The native preemption has been added to the kernel scheduler. 136 There is some report that the ULE scheduler was broken in some 137 machines and we encourage users using the ULE scheduler either 138 stick with a known good kernel, or temporarily switch to the 4BSD 139 scheduler as a workaround. 140 14120040630: 142 The netgraph ABI version number has been incremented to indicate 143 an incompatible change in the ABI. Old netgraph nodes will refuse 144 to attach until recompiled. Netgraph now uses mbuf tags to move 145 metadata and this commit removes its home-grown metadata facility. 146 Nodes should just recompile, unless they use metadata, in which 147 case the changes are simple; the file ng_ksocket.c serves as an 148 example of such changes. 149 150 This also broke i4b, although the compile problem has been papered 151 over. 152 15320040630: 154 ACPI has been updated to disable known-bad BIOS revisions. A message 155 will be printed on the console indicating that ACPI has been disabled 156 automatically and that the user should use a newer BIOS, if possible. 157 If you think ACPI does work on your system and want to override 158 this (i.e., for testing), set hint.acpi.0.disabled="0" at the 159 loader prompt. 160 16120040623: 162 pf was updated to OpenBSD-stable 3.5 and pflogd(8) is privilege 163 separated now. It uses the newly created "_pflogd" user/group 164 combination. If you plan to use pflogd(8) make sure to run 165 mergemaster -p or install the "_pflogd" user and group manually. 166 16720040622: 168 Network interface cloning has been overhauled. This change will 169 require a recompile of modules using cloning and modification of 170 external ones to the new API. __FreeBSD_version has been bumped 171 to 502119 to mark this change. Additionally, users creating 172 stf(4) interfaces via "ifconfig stf" will need to update their 173 scripts as this will create an interface named "stf" instead of 174 "stf0" and ifconfig will not print "stf0" to stdout. 175 17620040621: 177 On 20040524, the /etc/rc.d/nsswitch script was modified to 178 automatically create /etc/nsswitch.conf on startup if it did 179 not already exist. Unfortunately, an error in the man page 180 was carried over to the script, resulting in incorrect 181 nsswitch settings. The simplest remedy is to remove both 182 /etc/nsswitch.conf and /etc/host.conf; they will be recreated 183 during the next reboot. 184 18520040614: 186 The return value of sema_timedwait(9) has been changed to 187 make it consistent with cv_timedwait(9). Be sure to recompile 188 the ips module and any third-party modules which call 189 sema_timedwait. 190 19120040613: 192 ALTQ is now linked to the build. This breaks ABI for struct ifnet. 193 Make sure to recompile modules and any userland that makes use of 194 sizeof(struct ifnet). In order to get the altq headers in place 195 please recompile and reinstall world. 196 19720040607: 198 Splitting kern_thread.c into 2 files (adding kern_kse.c) 199 requires that you re-run config after updating your tree. 200 20120040601: 202 The MIDI drivers have been removed. Until the new module-friendly 203 ones are merged, remove or comment out midi and seq from your 204 kernel configuration. 205 20620040423: 207 Due to a new option in ipfw (versrcreach) the ipfw(8) command 208 needs to be recompiled. Normal accept/reject rules without 209 options are not affected but those with options may break until 210 ipfw(8) is recompiled. 211 21220040420: 213 Due to changes in the callout ABI, kernels compiled after this 214 date may be incompatible with kernel modules compiled prior to 215 20040406. 216 21720040414: 218 The PCI bus power state stuff has been turned on. If this causes 219 problems for your system, please disable it using the tunable 220 hw.pci.do_powerstate=0. 221 22220040412: 223 The bulk of the pci problems have been fixed, although the floppy 224 drive is still broken. 225 22620040410: 227 A substantial update to the pci bus resource and power management 228 have been committed. Expect a bumpy ride for a few days until 229 the unanticipated problems have been resolved. 230 23120040409: 232 Due to changes in the the Yarrow initialization process, 233 /dev/random needs to be fed before operations requiring 234 temp files can succeed in single user mode. This includes 235 running "make installworld". /dev/random may be fed by running 236 "/etc/rc.d/initrandom start" or with 20040415 source by running 237 "/etc/rc.d/preseedrandom". 238 23920040322: 240 The debug.mpsafenet tunable controls whether the kernel Giant 241 lock is held across the lower levels of the network stack, and 242 by default is turned off. In the few days following 20040322, 243 the behavior of debug.mpsafenet will change such that this 244 tunable controls Giant over all levels of the network stack. 245 If you are currently setting debug.mpsafenet to 1, you should 246 set it back to 0 (the default) again during the change-over. 247 An additional note will be added to UPDATING when sufficient 248 locking is merged to permit this to take place. 249 25020040310: 251 The FreeBSD/sparc64 platform is changing time_t from 32-bits to 252 64-bits. This is a very major incompatible change, so people 253 using FreeBSD/sparc64 *must* read the UPDATING.64BTT file for 254 detailed instructions on how to make this upgrade. People 255 upgrading FreeBSD on other platforms can ignore this event. 256 25720040308: 258 The packet filter (pf) is now installed with the base system. Make 259 sure to run mergemaster -p before installworld to create required 260 user account ("proxy"). If you do not want to build pf with your 261 system you can use the NO_PF knob in make.conf. 262 Also note that pf requires "options PFIL_HOOKS" in the kernel. The 263 pf system consists of the following three devices: 264 device pf # required 265 device pflog # optional 266 device pfsync # optional 267 26820040303: 269 If you are having trouble with the libc_r -> libpthread transition 270 (see the 20040130 entry), place the following lines at the top of 271 /etc/libmap.conf: 272 273 libc_r.so.5 libpthread.so.1 274 libc_r.so libpthread.so 275 276 This will cause all programs and libraries linked against libc_r 277 to use libpthread instead. 278 27920040226: 280 Some sshd configuration defaults have changed: protocol version 1 281 is no longer enabled by default, and password authentication is 282 disabled by default if PAM is enabled (which it is by default). 283 OpenSSH clients should not be affected by this; other clients may 284 have to be reconfigured, upgraded or replaced. 285 28620040225: 287 The ABIs defined in <resolv.h> and <netdb.h> have been updated 288 to support improved reentrancy. Multi-threaded programs that 289 reference the "_res" or "h_errno" symbols may experience some 290 problems if they are not recompiled. Single-threaded programs 291 should remain unaffected. 292 29320040225: 294 routed has been updated in the base system from the vendor 295 sources, routed v2.27, from rhyolite.com. This change means that 296 for users who use RIP's MD5 authentication feature, FreeBSD 297 -CURRENT's routed is now incompatible with previous versions 298 of FreeBSD; however it is now compatible with implementations 299 from Sun, Cisco and other vendors. 300 30120040224: 302 The tcpcb structure has changed and makes a recompile of libkvm 303 and related userland network utilities necessary. 304 30520040222: 306 The cdevsw structure has changed in two externally visible ways. 307 First, the sense of the D_GIANT flag has changed to D_NEEDSGIANT. 308 Second, the d_version field must be filled in with D_VERSION. 309 Drivers outside the tree will need to be updated. 310 31120040207: 312 The /etc/rc.d/ttys script has been removed. It is no longer 313 necessary since devfs has been mandatory for some time. 314 31520040130: 316 libkse has been renamed back to libpthread and is now the 317 default threads library. The gcc -pthread option has also 318 been changed to link to libpthread instead of libc_r. For 319 alpha and sparc64 machines, libkse is not renamed and links 320 are installed so that libpthread points to libc_r. Until 321 the ports system is updated to handle this change, it is 322 recommended that folks install an /etc/libmap.conf(5) that 323 maps libc_r to libpthread. If you have any binaries or 324 libraries linked to libkse, then it is also recommended 325 that you map libkse to libpthread. Anyone that is using 326 nvidia supplied drivers and libraries should use a libmap.conf 327 that maps libpthread to libc_r since their drivers/libraries 328 do not work with libpthread. 329 33020040125: 331 ULE has entered into its probationary period as the default scheduler 332 in GENERIC. For the average user, interactivity is reported to be 333 better in many cases. On SMP machines ULE will be able to make more 334 efficient use of the available parallel resources. If you are not 335 running it now, please switch over, replacing the kernel option 336 SCHED_4BSD with SCHED_ULE. 337 33820040125: 339 Move LongRun support out of identcpu.c, where it hardly 340 belongs, into its own file and make it opt-in, not mandatory, 341 depending on CPU_ENABLE_LONGRUN config(8) option. 342 34320031213: 344 src/lib/libc/gen/initgroups.c:1.8 now causes logins to fail 345 if the login process is unable to successfully set the 346 process credentials to include all groups defined for the 347 user. The current kernel limit is 16 groups; administrators 348 may wish to check that users do not have over 16 groups 349 defined, or they will be unable to log in. 350 35120031203: 352 The ACPI module has been reactivated. It is no longer required 353 to compile ACPI support into kernels statically. 354 35520031112: 356 The statfs structure has been updated with 64-bit fields to 357 allow accurate reporting of multi-terabyte filesystem 358 sizes. You should build world, then build and boot the new kernel 359 BEFORE doing a `installworld' as the new kernel will know about 360 binaries using the old statfs structure, but an old kernel will 361 not know about the new system calls that support the new statfs 362 structure. 363 Note that the backwards compatibility is only present when the 364 kernel is configured with the COMPAT_FREEBSD4 option. Since 365 even /bin/sh will not run with a new kernel without said option 366 you're pretty much dead in the water without it. Make sure you 367 have COMPAT_FREEBSD4! 368 Running an old kernel after a `make world' will cause programs 369 such as `df' that do a statfs system call to fail with a bad 370 system call. Marco Wertejuk <wertejuk@mwcis.com> also reports 371 that cfsd (ports/security/cfs) needs to be recompiled after 372 these changes are installed. 373 374 ****************************DANGER******************************* 375 376 DO NOT make installworld after the buildworld w/o building and 377 installing a new kernel FIRST. You will be unable to build a 378 new kernel otherwise on a system with new binaries and an old 379 kernel. 380 38120031112: 382 Some netgraph string length constants have been changed. This 383 change requires the netgraph kernel modules and all netgraph 384 userland components to be in sync. Especially users who require 385 netgraph to boot need to make sure to have world and kernel in 386 sync before rebooting. 387 38820031111: 389 Hyperthreading logical CPU's are no longer probed by default 390 when using the MP Table. If ACPI is being used, then logical 391 CPUs will be probed if hyperthreading is enabled in the BIOS. 392 If ACPI is not being used and hyperthreading is enabled in the 393 BIOS, logical CPUs can be enabled by building a custom kernel 394 with the option MPTABLE_FORCE_HTT enabled. 395 39620031103: 397 The i386 APIC_IO kernel option has been replaced by 398 'device apic'. The ACPI module has also been temporarily 399 disabled, so ACPI must be statically compiled into your 400 kernel using 'device acpi' if you wish to use the ACPI driver. 401 40220031031: 403 The API and ABI of struct ifnet have been changed by removing 404 the if_name and if_unit members and replacing them with 405 if_xname, if_dname, and if_dunit. All network drivers and most 406 userland programs which include net/if_var.h must be updated 407 and recompiled. __FreeBSD_version has been bumped to 501113 to 408 reflect this change. 409 41020030928: 411 Changes to the cdevsw default functions have been made to remove 412 the need to specify nullopen() and nullclose() explicitly. 413 __FreeBSD_version bumped to 501110. 414 41520030926: 416 kiconv(3) has been added. mount_msdosfs(8), mount_ntfs(8) and 417 mount_cd9660(8) need to be in sync with kernel. 418 41920030925: 420 Configuring a system to use IPFILTER now requires that PFIL_HOOKS 421 also be explicitly configured. Previously this dependency was 422 magically handled through some cruft in net/pfil.h; but that has 423 been removed. Building a kernel with IPFILTER but not PFIL_HOOKS 424 will fail with obtuse errors in ip_fil.c. 425 42620030923: 427 Fix a bug in arplookup(), whereby a hostile party on a locally 428 attached network could exhaust kernel memory, and cause a system 429 panic, by sending a flood of spoofed ARP requests. See 430 FreeBSD-SA-03:14.arp. 431 43220030915: 433 A change to /etc/defaults/rc.conf now causes inetd to be started 434 with `-C 60' if it is not overridden in /etc/rc.conf. This 435 causes inetd to stop accepting connections from an IP address 436 that exceeds the rate of 60 connections per minute. 437 43820030829: 439 The following rc.d scripts have been removed and should be 440 deleted from your installation: atm2.sh atm3.sh devdb 441 localdaemons network1 network2 network3. Depending on when 442 you last updated world and used mergemaster(8) you may or 443 may not have problems during the rc boot sequence. The simplest 444 solution is an 'rm -rf /etc/rc.d/*' and then 'mergemaster -i'. 445 The atm2.sh atm3.sh and devdb scripts were removed some time 446 ago, so depending on when you installed -CURRENT these scripts 447 may or may not exist on your system. 448 44920030824: 450 ATAng has been committed. You need to build world as sys/ata.h 451 has changed, and userland atacontrol depends on it. 452 If you use ATA SW raids you need "device ataraid" in your 453 kernel config file, as it is no longer pulled in automatically. 454 45520030819: 456 The OFW_NEWPCI option has been turned on in the Sparc64 GENERIC kernel. 457 Among other things, this changes the device enumeration to be 458 closer to Solaris. Be aware that, this can even cause the machine 459 to not boot without manual intervention before the fstab is adjusted. 460 46120030728: 462 All current USB and Firewire quirks in da(4) have been deprecated 463 and will be removed for 5.2. If this causes failure for your 464 umass(4) devices, enable "options DA_OLD_QUIRKS" in your kernel 465 and send the output of "camcontrol inquiry da0" to scsi@freebsd.org 466 so the quirk can be re-enabled. 467 46820030724: 469 Problems with entry 20030714 have been corrected and no known issues 470 with /rescue and -j exist for host systems after this point in time. 471 47220030722: 473 FPU-less support has been removed from FreeBSD. Chances are you won't 474 notice. 386+387 support should still work after this change, but 475 it is now a minimum requirement for the i386 port that you have real 476 FPU hardware. 477 47820030714: 479 Some people are having problems with changes related to /rescue. 480 If you are building -j N, you will need to define NO_RESCUE. Others 481 will need to define it if /rescue has issues with their environment. 482 People should report those issues to current@. 483 48420030711: 485 gcc was upgraded to 3.3. You are advised to not build -DNOCLEAN 486 across this point. Further, it might be a good idea to remove 487 /usr/obj. 488 48920030610: 490 Remove deprecated locale names and transition period code 491 for them, finishing switching to the new scheme. Check your 492 LANG environment variable. 493 49420030609: 495 CCD has been changed to be a fully GEOMified class. Kernel 496 and ccdconfig(8) needs to be in sync, this is particularly 497 important to remember beforehand if your source tree is on 498 a ccd device. Consider making a copy of the old ccdconfig 499 into /boot/kernel.good or wherever you keep your backup 500 kernel. 501 50220030605: 503 There was a small window in which sed(1) was broken. If you 504 happen to have sed(1) installed during that window, which is 505 evidenced by an inability to build world with the failure 506 given below, you need to manually build and install sed(1) 507 (and only sed(1)) before doing anything else. This is a one- 508 time snafu. Typical failure mode: 509 510 In file included from /usr/src/contrib/binutils/bfd/targets.c:1092: 511 targmatch.h:7:1: null character(s) ignored 512 targmatch.h:12:1: null character(s) ignored 513 targmatch.h:16:1: null character(s) ignored 514 : 515 516 The window of "sed(1)-uction" is from Wed Jun 4 15:31:55 2003 UTC 517 to Thu Jun 5 12:10:19 2003 UTC (from rev 1.30 to rev 1.31 of 518 usr.bin/sed/process.c). 519 52020030505: 521 Kerberos 5 (Heimdal) is now built by default. Setting 522 MAKE_KERBEROS5 no longer has any effect. If you do NOT 523 want the "base" Kerberos 5, you need to set NO_KERBEROS. 524 52520030502: 526 groff has been updated. If you try to do a buildworld and 527 get an infinite loop in troff, update to May 4th or newer. If you 528 have a newer kernel than userland, you may need to set the OSRELDATE 529 to 500110 in your environment before starting a buildworld. 530 53120030501: 532 The old rc system has been removed. Please report any problems 533 to freebsd-rc@yahoogroups.com, and/or freebsd-current@freebsd.org. 534 Your personal versions of these files will not be removed, so you can 535 continue to use them. However, you should take great care when updating, 536 especially when using mergemaster, since the compatibility code that 537 utilizes these old scripts has also been removed. 538 53920030423: 540 A bug has been fixed in /dev/devctl which would cause devd 541 to hang on boot, were it not for a workaround in devd. The 542 work around in devd will be removed around 20030507. You 543 have until then to upgrade your kernel before updating 544 userland. In general, you should have a userland and 545 kernel that's in sync with each other. However, given the 546 effects of this bug (hang on boot when starting devd), some 547 allowances are made. 548 54920030329: 550 Alphas with libc from between 20030312 and 20030329 exhibit 551 floating point exceptions (FPEs), most notably in awk(1) 552 while upgrading the system through a buildworld. 553 554 So, to successfully upgrade your Alpha, you must either 555 downgrade your libc.so to a pre-20030312 version, or update 556 /usr/share/mk/bsd.cpu.mk to revision 1.26 which adds -mieee 557 to CFLAGS, then forcibly rebuild and install libc: 558 559 cd /usr/src/lib/libc && \ 560 make cleandir && make obj && \ 561 make -DNOMAN -DNOPROFILE all && \ 562 make -DNOMAN -DNOPROFILE install 563 56420030208: 565 sendmail 8.12.7 has been imported. It has one important 566 change for IPv6 users. The default submit.mc now uses 567 '[127.0.0.1]' instead of 'localhost' meaning only IPv4 is 568 used to connect to the MTA. Users on IPv6-only machines 569 will need to edit /etc/mail/submit.mc appropriately. 570 57120030128: 572 NODEVFS option has been removed and DEVFS thereby made standard. 573 This makes all references to MAKEDEV obsolete, and they should 574 be removed when convenient. 575 57620030126: 577 The name of the device for the ofw console has changed, sparc64 users 578 must run mergemaster to update their installed /etc/ttys. 579 58020030125: 581 The scheduler framework has grown a second scheduler and consequently 582 you must specify one and only one scheduler in your kernel config. 583 The cvs config files have been updated to use the old scheduler 584 which may be selected via 'options SCHED_4BSD'. If you would like 585 to try the new, much more experimental, scheduler please try 586 'options SCHED_ULE' and contribute to the arch@ discussion. 587 58820030115: 589 A new version of the wi driver has been imported into the tree. 590 One now must have device wlan in the config file for it to operate 591 properly. 592 593 In addition, there have been some changes to how wi devices are 594 configured for point to point links to bring it more in line 595 with the former way of doing things, as well as compatibility 596 with NetBSD. 597 59820021222: 599 For a period after the GCC 3.2.1 import (from 12/04 to 12/22), GCC 600 used an incompatible form of ABI for returning structures and unions 601 which FreeBSD's GCC maintainers were not aware of relative to previous 602 versions of FreeBSD. We have gone back to the ABI for now, and any 603 code compiled which is required to interoperate with other code (not 604 built at the same time) returning structs or unions should be 605 rebuilt. 606 60720021216: 608 A name change in /etc/netconfig has been reverted to stay 609 compatible with suns TIRPC and also with NetBSD. You need 610 to run mergemaster after make world. A new libc does still work 611 with an outdated /etc/netconfig for some time, but you'll get 612 a warning. This warning will be removed in 20030301. 613 61420021202: 615 The recent binutils upgrade marks a kernel flag day on 616 sparc64: modules built with the old binutils will not work 617 with new kernels and vice versa. Mismatches will result in 618 panics. Make sure your kernel and modules are in sync. 619 62020021029: 621 The value of IPPROTO_DIVERT has changed. Make sure to keep 622 your kernel, netstat, natd and any third-party DIVERT 623 consumers in sync. 624 62520021024: 626 Old, compatibility slices have been removed in GEOM kernels. 627 This means that you will have to update your /etc/fstab to 628 not use disk devices of the form /dev/ad0a. Instead, you 629 now must specify /dev/ad0s1a, or whatever slice your FreeBSD 630 partition really is on. The old device names have gone 631 away, so if you use them anywhere else, you must also adjust 632 those uses. (This doesn't affect the disks formatted in 633 the ``dangerously-dedicated'' mode.) 634 63520021023: 636 Alphas with kernels from between 20020830 and 20021023 and/or 637 rtld (ld-elf.so.1) older than 20021023 may experience problems 638 with groff while doing a buildworld (kernel: "out of memory", 639 fixed in rev 1.129 of kern/imgact_elf.c; rtld: "too few PT_LOAD 640 segments", fixed in rev 1.8 of libexec/rtld-elf/map_object.c). 641 642 So, to successfully upgrade your Alpha, you must either 643 upgrade your kernel and rtld first (which might be a bit 644 tricky), or avoid running the bootstrapped groff during the 645 "transitional" buildworld. To avoid running groff during the 646 transitional upgrade run make buildworld with -DNOMAN, 647 -DNO_SHAREDOCS, and -DNO_LPR. 648 64920020831: 650 gcc has been upgraded to 3.2. It is not all binary compatible 651 with earlier versions of gcc for c++ programs. All c++ 652 programs and libraries need to be recompiled. 653 654 Also, if you encounter g++ issues, rm /usr/include/g++/* before 655 doing an installworld to make sure that stale files are removed. 656 65720020827: 658 Our /etc/termcap now has all the entries from the XFree86 xterm 659 almost unchanged. This means xterm now supports color by default. 660 If you used TERM=xterm-color in the past you now should use 661 TERM=xterm. (xterm-color will lead to benign warnings). 662 66320020815: 664 A "bug" in gcc(1) that was hiding warning in system headers was 665 fixed. It's probably time to add -DNO_WERROR to your make line 666 again. 667 66820020729: 669 COPY is being deprecated. The 20010530 change was reverted, as 670 it causes far more pain than was expected, and to always compare 671 before installing, please use INSTALL="install -C" again. The 672 -C option is now silently ignored when used with the -d option. 673 67420020702: 675 Problems with libc_r clients like KDE and GNOME have been resolved. 676 There are still some minor problems with some signals but the 677 system is stable enough for general use again. SMP is less so than UP 678 but each can successfully complete multiple buildworlds. 679 Libkvm needs to be recompiled due to KSE. 680 68120020701: 682 Now would be a bad time to upgrade. Something in or near the 683 KSE commit totally broke programs using libc_r like KDE and 684 GNOME. 685 68620020511: 687 The k5su utility installed as part of Kerberos 5 is no longer 688 installed with the set-user-ID bit set by default. Add 689 ENABLE_SUID_K5SU=yes to /etc/make.conf to have it installed 690 with the set-user-ID bit set. 691 69220020510: 693 Gcc 3.1 debugging format (cc -g) has changed from STABS to DWARF2. 694 Unfortunately our native GDB (at version 4.18) does not understand 695 the DWARF2 debugging format. Thus you must use `gcc -gstabs+' to 696 generated debugging information for our native GDB. 697 69820020510: 699 Due to the way CVS works, it may not properly update src/contrib/gcc 700 to the 3.1 sources. The easiest fix is to `rm -rf' src/contrib/gcc 701 and then do a cvs update. 702 70320020421: 704 When exec'ing set[ug]id executables, the kernel now ensures that the 705 stdio file descriptors (0..2) are open. See FreeBSD-SA-02:23.stdio. 706 70720020404: 708 New sendmail startup scripts have been installed to make it 709 easier to use alternative MTAs with FreeBSD. Setting the rc.conf 710 variable sendmail_enable to "NO" no longer prevents any sendmail 711 daemons from starting. Instead, either set sendmail_enable to 712 "NONE" or change mta_start_script to a script for starting 713 an alternative MTA. Setting mta_start_script to "" will 714 also prevent any MTA from being started at boot. 715 71620020403: 717 UCONSOLE is no longer a valid kernel option. 718 71920020315: 720 FreeBSD 5.0 DP-1 was basically branched today. 721 72220020225: 723 Warnings are now errors in the kernel. Unless you are a developer, 724 you should add -DNO_WERROR to your make line. 725 72620020217: 727 sendmail 8.12.2 has been imported. The sendmail binary is no 728 longer a set-user-ID root binary and the infrastructure to support 729 command line mail submission has changed. Be sure to run 730 mergemaster (especially for updating /etc/rc, /etc/defaults/rc.conf, 731 and /etc/mail) and read /etc/mail/README for more details. 732 733 Due to the import of sendmail 8.12.2, a new user and group are 734 required in order for sendmail to run as a set-group-ID 735 binary. A 'make installworld' will use the new user and group 736 to set the owner and group of /var/spool/clientmqueue and will 737 fail if the new user and group do not exist. The 'smmsp' user 738 and group must be merged from src/etc/group and 739 src/etc/master.passwd before using 'make installworld'. 740 'mergemaster -p' will do this. You may need to install 741 mergemaster before this will work if you are updating from a 742 very old version of current. The updating recipe has changed 743 as of this date. 744 74520020112: 746 The preferred configuration method for PAM is now /etc/pam.d/ 747 rather than /etc/pam.conf. If you have an unmodified 748 pam.conf, just delete it after your next mergemaster run. If 749 you have local modifications, you can use 750 /usr/src/etc/pam.d/convert.pl to incorporate them into your 751 /etc/pam.d. 752 753 Please see the following url for more details: 754http://www.freebsd.org/cgi/mid.cgi?db=mid&id=<xzp6667fyoa.fsf@flood.ping.uio.no> 75520011229: 756 If anyone here is already using the new rc.conf(5) variable 757 networkfs_types, please note that it has changed 758http://www.freebsd.org/cgi/mid.cgi?db=mid&id=<9744.1009655556@axl.seasidesoftware.co.za> 759 76020011220: 761 sys/i4b/driver/i4b_ispppsubr.c has been retired. This file 762 started out its life in the ISDN4BSD project as an offspring 763 from sys/net/if_spppsubr.c, which eventually got a life of its 764 own. All the accumulated features and bug fixes of the i4b 765 version have now been merged back into the base system's 766 version now. The only user-visible change resulting from this 767 is that i4b's sppp(4) interfaces are to be managed with 768 spppcontrol(8) again, since ispppcontrol(8) has been retired 769 as well. (There has never been rc file support for 770 ispppcontrol in -current, but only in -stable. That will be 771 reverted by the time the changes are MFCed.) 772 77320011215: 774 The fdc(4) driver has been updated and now automatically 775 recognizes media in `standard' formats (like 1440 KB and 776 720 KB for a 3.5" high-density drive) when accessing the 777 default device node (e. g. /dev/fd0). The old variety of 778 floppy device nodes /dev/fd*.* is no longer present by 779 default, devices can be created (in DEVFS) on demand. They 780 will need to be customized then for `odd' densities using 781 fdcontrol(8). 782 78320011209: 784 The bugs in procfs' debugging support code have been fixed, 785 and truss(1) now works again. 786 78720011207: 788 Daily security checks have been split out to use the periodic(8) 789 scripts. Some change in configuration may be necessary. Please 790 see 791http://www.freebsd.org/cgi/mid.cgi?db=mid&id=<20011207155805.R8975@blossom.cjclark.org> 792 for details. 793 79420011204: 795 sos added VCD/SVCD support to ata driver and that needs the 796 kernel and burncd to be in sync. 797 79820011203: 799 The procfs pseudo-filesystem has now been converted to use the 800 pseudofs framework. If you have 'options PROCFS' in your 801 kernel config, you'll need to add 'options PSEUDOFS' if it's 802 not there already. 803 804 This change temporarily breaks truss(1); use ktrace(1) instead 805 until the issue has been resolved. 806 80720011202: 808 A security hole in OpenSSH involving `UseLogin yes' has been 809 patched. 810 81120011126: 812 You need to remove /usr/obj/.../usr.bin/tip before rebuilding 813 after this date. You need to do this only once. 814 81520011103: 816 Most of the awk issues have been resolved. Some rough 817 edges may be left, but for the most part things should be 818 back to "normal." For CURRENT's usual definition of "normal." 819 82020011030: 821 Awk has been upgraded to the one true awk from bell labs. Expect 822 choppy waves in the upgrade process. 823 82420011030: 825 The asr driver problem has been resolved. 826 82720011027: 828 Due to changes in other parts of the system, the asr driver 829 now causes the system to panic on boot. Do not use it pending 830 correction. Comment it out of any kernel config file that you 831 try to use from this date forward. 832 83320011025: 834 When crossbuilding, use TARGET=xxx where you used to use 835 MACHINE=xxx. You don't need to set TARGET_ARCH and TARGET, 836 unless you are changing both of them. To cross build pc98 on 837 an alpha, for example, you need to set TARGET=pc98 and 838 TARGET_ARCH=i386. 839 84020011001: 841 The kernel interface that burncd depends on has changed. 842 You must recompile both the kernel and userland applications 843 at the same time. 844 84520010929: 846 When crossbuilding, please set TARGET_ARCH rather than 847 MACHINE_ARCH to indicate the target. In the future, one will 848 set TARGET_MACHINE where you set MACHINE now. At the moment, 849 setting MACHINE alone for same MACHINE_ARCH machines works 850 (eg, you can build pc98 on an i386 machine and vice versa). 851 85220010927: 853 Some weird problems result from using ACPI on some machines. 854 To disable ACPI you can add 855 hint.acpi.0.disabled="1" 856 to /boot/loader.conf (or by putting set X=Y at the boot 857 loader "ok" prompt). 858 859 Alternatively, you can remove it from /boot/kernel/acpi.ko 860 or use the MODULES_OVERRIDE function in your kernel config 861 file and not list acpi in that list. 862 86320010924: 864 The buildworld has been fixed. You may need to install 865 the 4.x compatibility libraries for some old binaries 866 to work. Add COMPAT4X=true to your /etc/make.conf to 867 get them installed on every installworld, or execute the 868 following to get them installed only once: 869 cd src/lib/compat/compat4x.<arch> 870 make all install 871 You will see ``__stdoutp undefined'' until you do this. 872 87320010919: 874 There's a bug in the world build process. The cross-tools 875 are build with the NEW headers, but the OLD libc.a. This 876 leads to all kinds of problems with the new libc. A temporary 877 workaround is to add 878 CFLAGS="-O -pipe -D_OLD_STDIO" 879 before building world when upgrading from 4.x to current. This 880 can be removed afterwards. 881 882 A proper fix to the buildworld target is needed. 883 88420010918: 885 Peter has committed his new kthread nfs client/server code. 886 NFS may be unstable after this date. 887 88820010912: 889 KSE has hit the tree. Lots of things are now different in 890 the kernel. While a few problems were introduced in the 891 initial commit, most of the major ones have been found and 892 corrected. 893 89420010901: 895 In OLDCARD, CardBus bridges appear to be stable. The work 896 arounds described in the 20010604 entry are now no longer 897 necessary and will be ignored. Most insert/remove problems 898 have been rectified around this date. 899 90020010823: 901 named now runs as user bind and group bind rather than as 902 root. If named_enable is set to YES in /etc/rc.conf, ensure 903 that user bind is available in /etc/passwd (using vipw(8)) 904 and that group bind is available in /etc/group. Also make 905 sure that user or group bind has read (and not write) 906 permission for your name server configuration and that it 907 has read and write permission for your slave zone files and 908 directory. 909 910 If you wish to continue to run named as root (a less secure 911 alternative), add a line to /etc/rc.conf saying 912 913 named_flags= 914 91520010709: 916 The PAM libraries have had an API upgrade that is beyond 917 the ability of the shared library major number to handle. 918 It is manifested by PAM-using ports dumping core. The 919 solution is to rebuild those ports. 920 92120010628: 922 The kernel compile module has moved from src/sys/compile/FOO 923 to src/sys/${MACHINE}/compile/FOO. 924 92520010625: 926 The pccard modem issue from 20010613 has been corrected. 927 OLDCARD support is still a little weak in -current. slot 1 is 928 known not to work on some TI based cardbus bridges. Some 929 cardbus bridges do not properly detect insert/removal events. 930 IRQ configuration needs more safety belts. 931 93220010617: 933 Softupdates problems have been corrected. 934 93520010614: 936 Peter ripped out the linkerset support. You must, as always, 937 rerun config after you cvsup if you are using the traditional 938 kernel building methods. 939 94020010613: 941 pccard modems may not work with current after 20010604 date. Some 942 do, others result in panics. *MAKE*SURE* that you update your 943 config and /etc/rc.conf ala the 20010604 entry, or you will have 944 problems (this issue will be fixed, it just hasn't been yet). 945 94620010613: 947 SOFTUPDATES seem to be broken since the middle of May or so. Do not 948 use them in current. You can disable softupdates on all mounted 949 partitions, or remove SOFTUPDATES the kernel config file. 950 95120010612: 952 After Peter's commits to the hints code, people have been noticing 953 that certain devices are attached (or try to) twice. This is due 954 to having both static hints as well as a /boot/device.hints. To 955 work around this issue, please use only one or the other mechanism 956 until this bug is fixed. 957 958 Please note that a feature of config is that if you have config 959 file FOO and FOO.hints, it automatically adds FOO.hints to the 960 hints.c file, whether you want it to or not. 961 96220010610: 963 Locale names have changed to match other systems better. 964 96520010604: 966 pccard support for pci cards has been committed. You must change 967 your /etc/pccard.conf irq lines. It must match the irq used by 968 pcic device. Interrupt storms may result if you fail to do this. 969 Interrupt storms look a lot like a hang. 970 971 You must also install a new pccardd, otherwise you will get an 972 interrupt storm at card reset time (just after it tells you what 973 it is). 974 975 pccardd_flags="-I" is necessary for the time being. It tells pccardd 976 not to ask the kernel if the interrupt is really free or not before 977 using it. You can either change the /etc/pccard.conf irq lines to 978 match pcic, or add "-i X" to the pccardd_flags. 979 98020010530: 981 INSTALL=install -C is being deprecated. If you want to do this, 982 use COPY=-C instead. The former method will be supported for only 983 a limited time. If you see 984 985install: warning: the -d and -C options may not be specified together 986 987 in your makeworld, then you need to migrate towards using 988 COPY=-C. 989 99020010525: 991 It appears that vm is now stable enough to use again. However, 992 there may be other problems, so caution is still urged. alpha 993 definitely is in bad shape. 994 99520010521: 996 Minor repo damage has happened. This may cause problems 997 with cvsup of ports. If you get errors, please see 998 http://www.FreeBSD.org/cgi/query-pr.cgi?pr=27495 999 at the bottom for details on a workaround. The error message 1000 is 1001Updater failed: Cannot delete "/usr/ports/www/jakarta-tomcat/files": Directory not empty 1002 100320010520: 1004 Vm and/or swapping are busted on -current. Please be patient. 1005 100620010519: 1007 pccard has had much reorganizational work done to it over 1008 the past few days. Everything should still work, but if 1009 not, please contact imp@freebsd.org. 1010 101120010517: 1012 ata ioctl changed. Make sure to recompile both kernel and 1013 userland at the same time. 1014 101520010517: 1016 New ncurses imported. 1017 101820010512: 1019 DEVFS is now opt out, not opt in. Barring major problems, this 1020 will be the only way to go starting July 1. 1021 102220010504: 1023 OpenSSH has been updated to 2.9. Some defaults are different, 1024 including RhostsRSAAuthentication, which changes from yes to no. 1025 102620010502: 1027 Perl breakage in 20010501 was corrected at 14:18:33 PDT. 1028 102920010501: 1030 Building perl was broken at 02:25:25 PDT. 1031 103220010430: 1033 The bug in 20010429 was corrected at 07:35:37 PDT. It is safe to 1034 go back in the water. 1035 103620010429: 1037 A bad bug was committed at 04:48:42 PDT. Don't use kernels after 1038 this date, but before the correction date. 1039 104020010423: 1041 old fsck and new kernel interactions appear to have been fixed. 1042 104320010411: 1044 fsck and the kernel were changed to handle some optimizations 1045 to directory layout. This breaks backward compatibility. 1046 Update only if you understand that you must not use the old 1047 fsck with the new kernel ever. 1048 104920010330: 1050 fsck has changed the meaning of the pass column in /etc/fstab. 1051 Please see the cvs commit to fsck.8 or the fsck.8 man page for 1052 details. It is unclear if changes to /etc/fstab are necessary. 1053 105420010319: 1055 portmap had changed name to rpcbind for maximum POLA in your 1056 current world. /etc/hosts.{allow,deny} needs changes. nfs and 1057 other rpc based programs that rely on portmapper will not work 1058 without updates to /etc/hosts.{allow,deny} and /etc/netconfig. 1059 106020010315: 1061 ata subsystem changes. ATA_ENABLE_ATAPI_DMA, ATA_ENABLE_WC 1062 and ATA_ENABLE_TAGS are no longer kernel options. They have 1063 been replaced by tunables. See ata.4 for details. 1064 106520010312: 1066 The fxp driver was converted to use miibus. If you compile 1067 fxp into your kernel statically, you will need to add miibus. 1068 106920010312: 1070 The wi device now defaults to BSS (infrastructure) mode 1071 instead of ad-hoc. 1072 107320010310: 1074 /dev/urandom should be a symbolic link to /dev/random now. 1075 Users of current not using DEVFS need to run MAKEDEV std. 1076 ssh might not work if you don't. 1077 107820010303: 1079 The ed driver has been updated. It now allows mii attachments, 1080 which means that you must include the miibus in your kernel if 1081 you use the ed driver. 1082 108320010220: 1084 The problems with libc have been corrected. It is now mostly 1085 safe to go back into the water. 1086 108720010211: 1088 The size of FILE was changed. This breaks upgrading. If 1089 you must upgrade, be prepared for pain. It also breaks almost 1090 all binaries that you've compiled on -current. You are warned 1091 that before upgrading would be a good time to do a level 0 1092 dump of your system. No, really, I mean it this time. 1093 1094 To get to the new system, you'll need to use the following 1095 workaround. Hopefully this can be sorted out so that we 1096 don't have to move this to the updating section. 1097 1098 To get around the installworld problem, do: 1099 # cd /usr/src/usr.bin/sed 1100 # make install 1101 # cd /usr/src 1102 # make installworld 1103 If that doesn't work, then try: 1104 # make -k installworld 1105 # make installworld 1106 110720010207: 1108 DEVFS is now the default. If you use vinum, make sure that you 1109 do not include devfs in your kernel as problems result. 1110 111120010205: 1112 FFS_ROOT and CD9660_ROOT have been removed or deprecated. 1113 Remove them from your config. 1114 111520010122: 1116 ****************************** WARNING ****************************** 1117 buildkernel has been changed slightly 1118 ****************************** WARNING ****************************** 1119 KERNCONF replaces the variable KERNEL for buildkernel. You 1120 should update your scripts and make.conf accordingly. 1121 112220010119: 1123 config has changed to allow DEV_FOO as a replacement for NFOO. 1124 This requires a new config to build correctly. 1125 112620010116: 1127 The kernel option I386_CPU is now mutually exclusive with the 1128 other cpu types. If you have an i386 system, be sure that it 1129 only had this line. Remove it for all other configurations. 1130 113120010110: 1132 Changes to the kernel require it and burncd be in sync. 1133 113420010102: 1135 Everyone who has hw.sndunit set to something in 1136 /etc/sysctl.conf, it is now hw.snd.unit. 1137 113820010101: 1139 ex and vi were broken by some changes to sys/queue.h. If you 1140 have a bad vi, you will see make buildworld fail with a core 1141 dump while building termcap. You can work around this problem 1142 by adding -k to your make buildworld. This will cause the 1143 build to complete and install a new vi. Once that's done, you 1144 can rebuild again without the -k to pick up anything that 1145 might have been ignored by the -k option. 1146 1147 Others have suggested that you can just rebuild libc if your 1148 vi/ex is dynamically linked, but I've not received any reports 1149 of this working. 1150 115120001228: 1152 There have been some changes to libcrypt in -current. The 1153 libscrypt/libdescrypt symlink silliness is gone and the installed 1154 libcrypt is fully functional. Be aware of this. 1155 115620001218: 1157 Linksys Fast Ethernet PCCARD cards supported by the ed driver 1158 now require the addition of flag 0x80000 to their config line 1159 in pccard.conf(5). This flag is not optional. These Linksys 1160 cards will not be recognized without it. 1161 116220001205: 1163 Important new FreeBSD-version stuff: PAM support has been worked 1164 in, partially from the "Unix" OpenSSH version. This requires 1165 adding the following in pam.conf: 1166 1167 sshd auth sufficient pam_skey.so 1168 sshd auth required pam_unix.so try_first_pass 1169 sshd session required pam_permit.so 1170 117120001031: 1172 cvs updated to 1.11. 1173 117420001020: 1175 The random device needs more entropy, so you need to make sure 1176 that you've run mergemaster to get a /etc/rc which will seed 1177 /dev/random. If you don't and the system hangs after ldconfig, 1178 then banging on the keyboard randomly until it unhangs is one 1179 workaround. 1180 118120001010: 1182 ****************************** WARNING ****************************** 1183 Sendmail has been updated. 1184 ****************************** WARNING ****************************** 1185 o mail.local(8) is no longer installed as a set-user-id binary. 1186 o sendmail(8) is now built with STARTTLS support unless NO_OPENSSL 1187 is set. 1188 o The default /etc/mail/sendmail.cf disables the SMTP EXPN and VRFY 1189 commands. 1190 o Now using sendmail's version of vacation(1). 1191 o The sendmail cf building tools (contrib/sendmail/cf) are installed 1192 in /usr/share/sendmail/cf. 1193 o sendmail.cw changed to local-host-names 1194 1195 More details can be found at 1196 http://people.freebsd.org/~imp/UPDATING/sendmail-20001010 1197 119820001009: 1199 The ports tree's new layout is in place. Be sure to update 1200 your entire ports tree, or you will have problems. 1201 120220001006: 1203 The perl build procedure no longer installs miniperl, nor uses 1204 the installed miniperl. It is recommended that you delete 1205 /usr/bin/miniperl. 1206 120720001005: 1208 This weekend the ports tree will be updated to a new layout. 1209 It will be in an inconsistent state until noted in the UPDATING 1210 file, or with asami-san's message to the relevant mailing 1211 lists. With this new layout, you'll need to update the whole 1212 tree for anything to work. 1213 121420000928: 1215 There was a change in the passwd format. Need more information. 1216 121720000916: 1218 /boot/kernel/kernel.ko -> /boot/kernel/kernel change has taken 1219 place. Please update boot loader (not the boot blocks) at the 1220 same time as your kernel. 1221 122220000914: 1223 The new pmtimer device is necessary for laptops. Failure to 1224 include the device will cause suspended laptops losing time 1225 when they resume. Include 1226 device pmtimer 1227 in your config file and 1228 hint.pmtimer.0.at="isa" 1229 to your /boot/device.hints file. 1230 123120000911: 1232 The random device has been turned into a (pseudo-)device, 1233 rather than an option. The supplied kernel config files have 1234 been updated. You will need to do something similar in your 1235 own kernel config file. 1236 Remove: 1237 options RANDOMDEV 1238 Add: 1239 device random 1240 If you prefer to load the loadable module, you need to do 1241 nothing. 1242 124320000909: 1244 The random device module has been renamed from randomdev.ko to 1245 random.ko. You will need to edit your /boot/loader.conf to 1246 reflect this if you load this module at boot time. 1247 The line should read: 1248 random_load="YES" 1249 125020000907: 1251 The SMPNG commit has happened. It should work, but if it 1252 doesn't, fallback to the PRE_SMPNG CVS tag. There are likely 1253 to be a variety of minor issues. Please see 20000905 to make 1254 sure you don't have model loading problems which might at 1255 first blush appear related to SMP. 1256 125720000906: 1258 nsswitch has been imported from NetBSD. Among other things, 1259 this means that /etc/host.conf is no longer used. See 1260 nsswitch.conf(5) instead. Note that at boot time rc.network 1261 will attempt to produce a new nsswitch.conf file for you if you 1262 don't have one, and you have host.conf. 1263 126420000905: 1265 The ucred structure changed size. This breaks the interface 1266 that mountd uses. Trying to use an older mountd with a newer 1267 kernel guarantees a panic. This means that you need to use 1268 kernels newer than today only with matching mountd, but you 1269 needed to do that anyway with the boot loader changes. 1270 127120000905: 1272 The boot loader has been updated. The new default kernel is 1273 now /boot/kernel/kernel.ko. The new default module location 1274 is /boot/kernel. 1275 1276 You *MUST* upgrade your boot loader and kernel at the same time. 1277 The easiest way to do this is to do the buildworld/buildkernel/ 1278 installkernel/installworld dance. 1279 1280 Furthermore, you are urged to delete your old /modules directory 1281 before booting the new kernel, since kldload will find stale 1282 modules in that directory instead of finding them in the correct 1283 path, /boot/kernel. The most common complaint that this cures 1284 is that the linux module crashes your machine after the update. 1285 1286 if [ ! -d /boot/kernel.old ]; then 1287 mv /modules.old /boot/kernel.old 1288 chflags noschg /kernel.old 1289 mv /kernel.old /boot/kernel.old/kernel.ko 1290 chflags schg /boot/kernel.old/kernel.ko 1291 fi 1292 129320000904: 1294 A new issue with the sendmail upgrade has come to light. 1295 /etc/aliases has moved to /etc/mail/aliases. Mergemaster will 1296 incorrectly install the default aliases in /etc/mail rather than 1297 move the old one from /etc. So you'll need to manually move the 1298 file, create a symbolic link, remove the old /etc/aliases.db and 1299 run newaliases. For safety sake, you should stop sendmail 1300 while doing this and run the upgrade when locally sourced email 1301 is not likely to be generated. 1302 130320000825: 1304 /boot/device.hints is now required for installkernel to 1305 succeed. You should copy GENERIC.hints for your architecture 1306 into /boot/device.hints. If and only if you compile hints 1307 into your kernel, then this file may be empty. Please note, 1308 if you have an empty or missing /boot/device.hints file and 1309 you neglected to compile hints into your kernel, no boot 1310 messages will appear after the boot loader tries to start the 1311 kernel. 1312 131320000821: 1314 If you do NOT have ``options RANDOMDEV'' in your kernel and 1315 you DO want the random device then add randomdev_load="YES" to 1316 /boot/loader.conf. 1317 131820000812: 1319 suidperl is now always built and installed on the system, but 1320 with permissions of 511. If you have applications that use 1321 this program, you are now required to add ENABLE_SUIDPERL=true 1322 to /etc/make.conf. If you forget to do this, 1323 chmod 4511 /usr/bin/suidperl 1324 will fix this until the next build. 1325 132620000812: 1327 sendmail has been updated from 8.9.3 to 8.11.0. Some of the more 1328 visible changes that may immediately affect your configuration 1329 include: 1330 - New default file locations from src/contrib/sendmail/cf/README 1331 - newaliases limited to root and trusted users 1332 - MSA port (587) turned on by default 1333 - New queue file naming system so can't go from 8.11 -> 8.9 1334 - FEATURE(`rbl') renamed to FEATURE(`dnsbl') 1335 - FEATURE(`nullclient') is more full featured 1336 - FEATURE(`nouucp') requires an argument: `reject' or `nospecial' 1337 - mail.local FreeBSD-only -b option changed to -B 1338 - See src/contrib/sendmail/RELEASE_NOTES for more info 1339 134020000810: 1341 suidperl (aka sperl) is no longer build by default. You must 1342 specifically define BUILD_SUIDPERL to "true" for it to be build. 1343 Furthermore, we recommend that you remove /usr/bin/sperl* and 1344 /usr/bin/suidperl files from your system unless you have a 1345 specific use for it. 1346 134720000729: 1348 Networking defaults have been tightened. Anybody upgrading 1349 /etc/defaults/rc.conf needs to add the following lines to 1350 /etc/rc.conf if they want to have the same setup 1351 afterwards (unless the variables already are set, of course): 1352 # Enable network daemons for user convenience. 1353 inetd_enable="YES" 1354 portmap_enable="YES" 1355 sendmail_enable="YES" 1356 135720000728: 1358 If you have null_load="YES" in your /boot/loader.conf, you 1359 will need to change that to nullfs_load="YES". 1360 136120000728: 1362 The "installkernel" target has changed slightly. Now even if 1363 you override KERNEL e.g. 'make installkernel KERNEL=MYKERNEL' 1364 it will install the MYKERNEL file (built with the buildkernel 1365 target) as /kernel rather than /MYKERNEL. Those who have 1366 updated their /boot/loader.conf files to point to /MYKERNEL 1367 should remove that entry or perform manual rename of /kernel 1368 to /MYKERNEL. 1369 137020000711: 1371 If you use CVSUP or CTM to get CVS trees, AND you used to get 1372 the old crypto files from internat.freebsd.org AND you check 1373 out files from the CVS tree with the cvs command, please read 1374 http://people.freebsd.org/~imp/internat.txt 1375 for details on potential problems that you might have and how 1376 to get around them. 1377 1378 If you are merely a mirror, or don't answer yes to each of the 1379 clauses above, you needn't worry. 1380 138120000711: 1382 /etc/security has been updated to print the inode number of 1383 setuid programs that have changed. You will see a large spike 1384 in the number of changed programs the first time when you run 1385 mergemaster to get a new /etc/security. 1386 138720000710: 1388 /dev/random now has good entropy collection (from the keyboard 1389 and sysmouse drivers). Please ensure that either `options 1390 RANDOMDEV' is present in your kernel config file or that 1391 `randomdev_load="YES"' is in your /boot/loader.conf. If you do 1392 not have the /dev/random driver, OpenSSL (and consequently 1393 lots of crypto tools (like SSH)) will fail with strange 1394 errors. (see below, 20000624). 1395 1396 FreeBSD-current is safe again to run Crypto. 1397 139820000709: 1399 phk made the malloc default options AJ. This may slow things 1400 down and uncover other latent bugs in the code. If you need to 1401 run at full speed, you can disable this by doing the following: 1402 ln -s aj /etc/malloc.conf 1403 140420000706: 1405 libftpio's version was accidentally bumped a few days ago. This 1406 has been corrected. You may need to remove /usr/lib/libftpio.so.6 1407 before doing your next buildworld/installworld pair. It certainly 1408 won't hurt to remove it before the update procedure. It will 1409 break fetch until a new one is built, but ftp can be used in the 1410 interim if needed. 1411 141220000705: 1413 The crypto packages have changed for the cvsup. This has been done 1414 in a backward compatible way, but the old packages will go away at 1415 some point in the future. Look at /usr/share/examples/cvsup for 1416 details. 1417 141820000704: 1419 With the new sys/modules/sound/drivers/*, you will need to 1420 set SYSDIR until you do an installworld after July 7th. 1421 142220000704: 1423 rc.shutdown and rc will now call the rc.d scripts with start 1424 or stop. This may cause some harmless warnings from older 1425 rc.d scripts that haven't been updated. 1426 142720000630: 1428 The libfetch based version of fetch has gone into the tree. 1429 Minor problems may result on some of the less popular sites, 1430 which should be reported to des@freebsd.org. 1431 143220000625: 1433 From approximately this date forward, one must have the crypto 1434 system installed in order to build the system and kernel. 1435 While not technically strictly true, one should treat it as 1436 required and grab the crypto bits. If you are grabbing CVS 1437 trees, src-all and cvs-crypto should be treated as if they 1438 were required. You should check with the latest collections 1439 to make sure that these haven't changed. 1440 144120000624: 1442 Mark Murray just committed the first parts of a cleanup of 1443 /dev/zero, et al. This is also cleaning up /dev/random. 1444 The entropy is disconnected, so DO NOT USE VERSIONS OF FREEBSD 1445 -CURRENT FROM THIS POINT to 2000710 for cryptographic services 1446 until Mark can merge in the fixes to this work in progress. 1447 openssh and openssl should not be used to generate keys from this 1448 date to the completion of the work. 1449 1450 If you must operate at this reduced level of security, add ' 1451 options RANDOMDEV' to your kernel or modload the randomdev 1452 module. You may also need to copy a new MAKEDEV to /dev and 1453 recreate the random and urandom devices. 1454 145520000622: 1456 The license on the softupdates is now a standard 2 clause 1457 BSD license. You may need to remove your symbolic links 1458 that used to be required when updating. 1459 146020000621: 1461 Scott Flatman <sf@aracnet.com> sent in a decent write-up on 1462 the config file update procedure. 1463 http://people.freebsd.org/~imp/config-upd.html 1464 NOTE: LINT is gone. It has been replaced with NOTES. NOTES 1465 isn't buildable. However, you can generate a LINT file: 1466 cd /sys/<ARCH>/conf && make LINT 1467 146820000620: 1469 Binutils 2.10 have hit the tree, or will shortly. As soon 1470 as they do, the problem noted in 20000522 will be resolved and 1471 that workaround will no longer be required. 1472 147320000615: 1474 phk removed the compatibility creation of wd devices in the 1475 ad driver. If you haven't done so already, you must update 1476 your fstab, etc to use the ad devices instead of the wd 1477 devices. 1478 1479 In addition, you'll need to update your boot blocks to a 1480 more modern version, if you haven't already done so. Modern 1481 here means 4.0 release or newer (although older releases 1482 may work). 1483 148420000612: 1485 Peter took an axe to config(8). Be sure that you read his mail 1486 on the topic before even thinking about updating. You will 1487 need to create a /boot/device.hints or add a hints directive 1488 to your config file to compile them in statically. The format 1489 of the config file has changed as well. Please see GENERIC or 1490 NEWCARD for examples of the new format. 1491 1492 Indirectly, this also breaks USERCONFIG. Unless a newer entry 1493 says that it has been fixed, assume that must use the hints mechanism 1494 in the loader if you need to use a machine with very old ISA cards 1495 in it. 1496 149720000522: 1498 A new set of binutils went into the tree today. Anybody 1499 building a kernel after this point is advised that they need 1500 to rebuild their binutils (or better yet do a 1501 buildworld/installworld) before building a new kernel. 1502 1503 Due to bugs in binutils, using malloc options (eg /etc/malloc.conf 1504 or MALLOC_OPTIONS env var) J will cause ld to dump core. It 1505 is recommended that you don't set this option until the problem 1506 is resolved. 1507 150820000513: 1509 The ethernet drivers were all updated to clean up the BPF handling. 1510 151120000510: 1512 The problems with boot blocks on the alphas have been corrected. 1513 This will require some care in updating alphas. A new libstand 1514 is requires for the boot blocks to build properly. 1515 151620000503: 1517 Recompile all kld modules. Proper version dependency info 1518 is now available. 1519 152020000502: 1521 Modules have been disconnected from the buildworld tree and 1522 connected to the kernel building instead. 1523 152420000427: 1525 You may need to build gperf 1526 cd /usr/src/gnu/usr.bin/gperf && make depend all install 1527 when upgrading from 4.0 -> current. The build system now uses 1528 an option only in -current. 1529 153020000417: 1531 The method that we brand ELF binaries has changed to be more 1532 acceptable to the binutils maintainers. You will need to 1533 rebrand your ELF binaries that aren't native. One problem 1534 binary is the Linux ldconfig. After your make world, but 1535 before you reboot, you'll need to issue: 1536 brandelf -t Linux /compat/linux/sbin/ldconfig 1537 if you have Linux compatibility enabled on your machine. 1538 153920000320: 1540 If you have really bad/marginal IDE drives, you may find they 1541 don't work well. Use pio mode instead. The easiest way to 1542 cope if you have a problem combination is to add: 1543 /sbin/sysctl hw.ata.ata_dma=0 1544 to the start of /etc/rc.conf. 1545 154620000319: 1547 The ISA and PCI compatibility shims have been connected to the 1548 options COMPAT_OLDISA and COMPAT_OLDPCI. If you are using old 1549 style PCI or ISA drivers (i.e. tx, voxware, etc.) you must 1550 include the appropriate option in your kernel config. Drivers 1551 using the shims should be updated or they won't ship with 1552 5.0-RELEASE, targeted for 2001. 1553 155420000318: 1555 We've entered the traditional post release dumping party. 1556 Large kernel changes are being committed and are in the 1557 works. It is important to keep the systems' klds and kernel 1558 in sync as kernel interfaces and structures are changing. 1559 Before reporting kernel panics, make sure that all modules 1560 that you are loading are up to date. 1561 156220000315: 1563 If you are upgrading from an older version of FreeBSD, you 1564 need to update your boot blocks as well. 'disklabel -B ad0' 1565 will do the trick. This isn't critical until you remove your 1566 wd device entries in /dev, at which point your system will not 1567 boot. 1568 156920000315: 1570 4.0 RELEASE shipped. Please see the 4.0 UPDATING file for how 1571 to upgrade to 4.0 from 3.x. 1572 1573COMMON ITEMS: 1574 1575 # NOTE: 5.x below applies to 6.0-currrent as well, for the 1576 # momemnt. 4.any -> 5.any upgrade support will remain in 1577 # place for 6.0 current, but after 5.3 RELEASE, the 4.any -> 1578 # 6.0-current upgrade path will require moving through 5.3 1579 # RELEASE or newer. 1580 1581 General Notes 1582 ------------- 1583 Avoid using make -j when upgrading. From time to time in the 1584 past there have been problems using -j with buildworld and/or 1585 installworld. This is especially true when upgrading between 1586 "distant" versions (eg one that cross a major release boundary 1587 or several minor releases, or when several months have passed 1588 on the -current branch). 1589 1590 Sometimes, obscure build problems are the result of environment 1591 poisoning. This can happen because the make utility reads its 1592 environment when searching for values for global variables. 1593 To run your build attempts in an "environmental clean room", 1594 prefix all make commands with 'env -i '. See the env(1) manual 1595 page for more details. 1596 1597 To build a kernel 1598 ----------------- 1599 If you are updating from a prior version of FreeBSD (even one just 1600 a few days old), you should follow this procedure. With a 1601 /usr/obj tree with a fresh buildworld, 1602 make -DALWAYS_CHECK_MAKE buildkernel KERNCONF=YOUR_KERNEL_HERE 1603 make -DALWAYS_CHECK_MAKE installkernel KERNCONF=YOUR_KERNEL_HERE 1604 1605 To just build a kernel when you know that it won't mess you up 1606 -------------------------------------------------------------- 1607 This assumes you are already running a 5.X system. Replace 1608 ${arch} with the architecture of your machine (e.g. "i386", 1609 "alpha", "amd64", "ia64", "pc98", "sparc64", etc). 1610 1611 cd src/sys/${arch}/conf 1612 config KERNEL_NAME_HERE 1613 cd ../compile/KERNEL_NAME_HERE 1614 make depend 1615 make 1616 make install 1617 1618 If this fails, go to the "To build a kernel" section. 1619 1620 To rebuild everything and install it on the current system. 1621 ----------------------------------------------------------- 1622 # Note: sometimes if you are running current you gotta do more than 1623 # is listed here if you are upgrading from a really old current. 1624 1625 <make sure you have good level 0 dumps> 1626 <maybe fix /etc/fstab> [7] 1627 make buildworld 1628 make buildkernel KERNCONF=YOUR_KERNEL_HERE 1629 make installkernel KERNCONF=YOUR_KERNEL_HERE 1630 [1] 1631 <reboot in single user> [3] 1632 /etc/rc.d/preseedrandom [10] 1633 mergemaster -p [5] 1634 make installworld 1635 mergemaster [4] 1636 <reboot> 1637 1638 1639 To cross-install current onto a separate partition 1640 -------------------------------------------------- 1641 # In this approach we use a separate partition to hold 1642 # current's root, 'usr', and 'var' directories. A partition 1643 # holding "/", "/usr" and "/var" should be about 2GB in 1644 # size. 1645 1646 <make sure you have good level 0 dumps> 1647 <boot into -stable> 1648 make buildworld 1649 <maybe newfs current's root partition> 1650 <mount current's root partition on directory ${CURRENT_ROOT}> 1651 make installworld DESTDIR=${CURRENT_ROOT} 1652 make buildkernel KERNCONF=YOUR_KERNEL_HERE 1653 cp /usr/src/sys/${ARCH}/conf/GENERIC.hints \ 1654 ${CURRENT_ROOT}/boot/device.hints # as needed 1655 make installkernel KERNCONF=YOUR_KERNEL_HERE DESTDIR=${CURRENT_ROOT} 1656 cd /usr/src/etc; make distribution DESTDIR=${CURRENT_ROOT} # if newfs'd 1657 cp /etc/fstab ${CURRENT_ROOT}/etc/fstab # if newfs'd 1658 <edit ${CURRENT_ROOT}/etc/fstab to mount "/" from the correct partition> 1659 <reboot into current> 1660 <do a "native" rebuild/install as described in the previous section> 1661 <maybe install compatibility libraries from /usr/src/lib/compat> 1662 <reboot> 1663 1664 1665 To upgrade in-place from 4.x-stable to current 1666 ---------------------------------------------- 1667 # 5.x uses more space than 4.x. Also, the location of kernel 1668 # modules has changed. If you are installing 5.0 onto a 4.x 1669 # system, you'll need about 30MB of free disk space on your / 1670 # partition. If you have less than this, you may encounter difficult 1671 # to back out of problems with this procedure. If /tmp is on 1672 # the / partition, you may want to completely remove all its content 1673 # before upgrading, as this can be a common source of shortage of 1674 # space on /. 1675 1676 <make sure you have good level 0 dumps> 1677 <maybe fix /etc/fstab> [7] 1678 make buildworld [9] 1679 make buildkernel KERNCONF=YOUR_KERNEL_HERE [8] 1680 cp sys/${MACHINE}/conf/GENERIC.hints /boot/device.hints [2] 1681 make installkernel KERNCONF=YOUR_KERNEL_HERE 1682 cd sys/boot ; make STRIP="" install [6] 1683 [1] 1684 <reboot in single user> [3] 1685 /usr/src/etc/rc.d/preseedrandom [10] 1686 mergemaster -p [5] 1687 rm -rf /usr/include/g++ 1688 make installworld 1689 mergemaster -i [4] 1690 <reboot> 1691 1692 Make sure that you've read the UPDATING file to understand the 1693 tweaks to various things you need. At this point in the life 1694 cycle of current, things change often and you are on your own 1695 to cope. The defaults can also change, so please read ALL of 1696 the UPDATING entries. 1697 1698 Also, if you are tracking -current, you must be subscribed to 1699 freebsd-current@freebsd.org. Make sure that before you update 1700 your sources that you have read and understood all the recent 1701 messages there. If in doubt, please track -stable which has 1702 much fewer pitfalls. 1703 1704 [1] If you have third party modules, such as vmware, you 1705 should disable them at this point so they don't crash your 1706 system on reboot. 1707 1708 [2] If you have legacy ISA devices, you may need to create 1709 your own device.hints to reflect your unique hardware 1710 configuration. 1711 1712 [3] From the bootblocks, boot -s, and then do 1713 fsck -p 1714 mount -u / 1715 mount -a 1716 cd /usr/src 1717 adjkerntz -i # if CMOS is wall time 1718 Also, when doing a major release upgrade, it is required that 1719 you boot into single user mode to do the installworld. 1720 For the 4.x -> 5.x upgrade, you will also see many messages about 1721 needing to recompile your userland. These are harmless and can 1722 be ignored while you proceed to the next step. 1723 1724 [4] Note: This step is non-optional. Failure to do this step 1725 can result in a significant reduction in the functionality of the 1726 system. Attempting to do it by hand is not recommended and those 1727 that pursue this avenue should read this file carefully, as well 1728 as the archives of freebsd-current and freebsd-hackers mailing lists 1729 for potential gotchas. 1730 1731 [5] Usually this step is a noop. However, from time to time 1732 you may need to do this if you get unknown user in the following 1733 step. It never hurts to do it all the time. You may need to 1734 install a new mergemaster (cd src/usr.sbin/mergemaster && make 1735 install) after the buildworld before this step if you last updated 1736 from current before 20020224 or from -stable before 20020408. 1737 1738 [6] 4.x boot loader can be used to boot a 5.x system, however 1739 it is difficult to do that at best. If you wish to try, then 1740 you should interrupt the boot and at the ok prompt type: 1741 ok unload 1742 ok boot /boot/kernel/kernel 1743 If this fails to work, you must install a new boot loader as 1744 described here. 1745 1746 [7] Before you upgrade, please make sure that you are not using 1747 compatibility slices. These are device names of the form, on i386 1748 and other architectures that use MBR slicing, /dev/ad0a without the 1749 actual slice name. Chances are excellent that these will break. 1750 You generally must update these entries to use the post FreeBSD 1751 2.x form of /dev/ad0s1a. 1752 1753 [8] In order to have a kernel that can run the 4.x binaries 1754 needed to do an installworld, you must include the COMPAT_FREEBSD4 1755 option in your kernel. Failure to do so may leave you with a system 1756 that is hard to boot to recover. 1757 1758 [9] When checking out sources, you must include the -P flag to have 1759 cvs prune empty directories. Also, if CPUTYPE is defined in your 1760 /etc/make.conf, make sure to use the "?=" instead of the "=" assignment 1761 operator, so that buildworld can override the CPUTYPE if it needs to. 1762 In case you would like to avoid installing new packages of everything, 1763 you might want to uncomment the "COMPAT4X= YES" entry, so that 4.x 1764 compatibility libraries are built which should allow you to continue 1765 using your existing software for a while. 1766 1767 [10] In order to create temporary files, /dev/random must be 1768 initialized by feeding data into it. /usr/src/etc/rc.d/preseedrandom 1769 takes care of this. 1770FORMAT: 1771 1772This file contains a list, in reverse chronological order, of major 1773breakages in tracking -current. Not all things will be listed here, 1774and it only starts on March 15, 2000. Updating files can found in 1775previous releases if your system is older than this. 1776 1777Copyright information: 1778 1779Copyright 1998, 2002 M. Warner Losh.
