1# Updating Information for DragonFly users. 2# 3# 4# This file should warn you of any pitfalls which you might need to work around 5# when trying to update your DragonFly system. The information below is 6# in reverse-time order, with the latest information at the top. 7# 8# If you discover any problem, please contact the bugs@lists.dragonflybsd.org 9# mailing list with the details. 10 11+-----------------------------------------------------------------------+ 12+ UPGRADING DRAGONFLY FROM 5.6 TO LATER VERSIONS + 13+-----------------------------------------------------------------------+ 14 15LIBOPIE, LIBMD REMOVED 16---------------------- 17 18Removal of OPIE requires /etc/pam.d/ configs to be updated. 19 20+-----------------------------------------------------------------------+ 21+ UPGRADING DRAGONFLY FROM 5.4 TO LATER VERSIONS + 22+-----------------------------------------------------------------------+ 23 24GCC50 REMOVED 25------------- 26 27The GCC50 compiler has been retired. It has been replaced by a GCC80. 28The default alternative compiler has stayed the same - GCC47. 29 30 31PUFFS, PUTTER AND LIBREFUSE REMOVED 32----------------------------------- 33 34The puffs(4)/putter(4) subsystem has been removed, along with librefuse, 35libpuffs, and the mount_psshfs(8) utility. All of these have never been 36working correctly. 37 38FFS_ROOT OPTION REMOVED 39----------------------- 40 41The FFS_ROOT kernel configuration option has been finally removed, after 42having been a no-op since 4.9. That means users using a custom kernel 43configuration file that still contains it need to remove the option from 44that file. 45 46+-----------------------------------------------------------------------+ 47+ UPGRADING DRAGONFLY FROM 5.2 TO LATER VERSIONS + 48+-----------------------------------------------------------------------+ 49 50DIGI, RP AND SI DRIVERS REMOVED 51------------------------------- 52 53The digi(4), rp(4) and si(4) serial drivers have been removed. None of 54them were in our default kernel configuration file. The sicontrol(8) 55utility was removed, too. 56 57MKINITRD COMMAND REMOVED 58------------------------ 59 60The mkinitrd(8) command is removed and its functionality is replaced by 61the new "initrd" make target. After rebooting into the new world and 62verifying everything works, execute "make initrd" to upgrade the rescue 63tools and initrd image. 64 65IPSEC, IPSEC_ESP AND IPSEC_DEBUG REMOVED FROM VKERNEL64 CONFIG 66-------------------------------------------------------------- 67 68IPsec has been removed from the system. Of our standard kernel 69configurations, only the virtual kernel one had it. People running 70vkernels with configuration files derived from our VKERNEL64 will 71have to remove these options manually. 72 73+-----------------------------------------------------------------------+ 74+ UPGRADING DRAGONFLY FROM 5.0 TO LATER VERSIONS + 75+-----------------------------------------------------------------------+ 76 77VIRTIO_PCI REMOVED FROM KERNEL CONFIG 78------------------------------------- 79 80The "device virtio_pci" line in X86_64_GENERIC has been removed. People 81with configuration files derived from it have to remove it manually. 82 83VARIOUS 'R' COMMANDS AND DAEMONS REMOVED 84---------------------------------------- 85 86rcp(1), rlogin(1), rlogind(8), rsh(1) and rshd(8) have been removed. 87For those that still need them, there is the net/bsdrcmds port. 88 89VARIOUS FORMER OPTIONS REMOVED 90------------------------------ 91 92Various former kernel configuration options which had been no-ops for 93some time were completely removed: SYSVMSG, SYSVSEM, SYSVSHM, P1003_1B, 94_KPOSIX_VERSION and DSCHED_FQ. Users that have any of these still in 95their kernel configuration files have to remove them. 96 97BOOTSTRAPPING LIMITED FROM PRE 4.4 98---------------------------------- 99 100Upgrading to 5.1 and later versions now require at least 4.4 in 101preparations for upcoming base compilers updates. 102 103IF_PPP, PPPD, IF_FAITH, AND FAITHD REMOVED 104------------------------------------------ 105 106if_ppp has been replaced by "user ppp", i.e. ppp(8) and tun(4). It had 107already been removed from our default kernel configuration before 5.0, 108so only people with custom configurations based on earlier X86_64_GENERIC 109will have to remove it manually. 110 111The faith(4) interface has been completely removed after it had also 112been removed from our default kernel configuration. 113 114+-----------------------------------------------------------------------+ 115+ UPGRADING DRAGONFLY FROM 4.8 TO LATER VERSIONS + 116+-----------------------------------------------------------------------+ 117 118FFS_ROOT OPTION DISABLED 119------------------------ 120 121The FFS_ROOT option has been made a no-op and will be completely removed 122at some point in the future. Users with a custom kernel configuration 123can remove this option from it now. 124 125+-----------------------------------------------------------------------+ 126+ UPGRADING DRAGONFLY FROM 4.6 TO LATER VERSIONS + 127+-----------------------------------------------------------------------+ 128 129DSA OPENSSH KEYS DEPRECATED 130--------------------------- 131 132Note that DSA OpenSSH keys were deprecated in the 4.6 to 4.8 release. 133If you are upgrading from a release older than 4.8 and use DSA OpenSSH 134keys, please update your private/public key pair or risk locking 135yourself out. 136 137AHC, AHD, AIC, NCV, NSP AND STG DRIVERS REMOVED 138----------------------------------------------- 139 140They were all in our X86_64_GENERIC kernel configuration file, along with 141the AHC_REG_PRETTY_PRINT and AHD_REG_PRETTY_PRINT options, so any custom 142configuration files derived from it need adjustment. 143 144PORTAL FILE SYSTEM REMOVED 145-------------------------- 146 147It has been broken for a long time now. 148 149BINUTILS 2.27 REPLACES 2.24, PRIMARY 150------------------------------------ 151 152The oldest of the two versions of Binutils, version 2.24, was removed 153and replaced with Binutils 2.27. It becomes the primary version version 154of binutils and version 2.25 becomes the alternate. 155 156The accepted values of BINUTILSVER are now "binutils227" (default) and 157"binutils225". The building of Binutils 2.25 can be prevented by setting 158NO_ALTBINUTILS=yes in make.conf. 159 160COMPAT_43 KERNEL OPTION REMOVED 161------------------------------- 162 163It was commented out in our default configs for several years now, but 164might still be present in custom configs created before Nov. 2011. 165 166OPENSSL REMOVED 167--------------- 168 169OpenSSL has been removed from base and replaced with a private version of 170LibreSSL. The previously installed OpenSSL libraries, headers, and man 171pages will remain on the system unless the "make upgrade" command is 172specifically instructed to remove them. To do this, define 173REMOVE_OPENSSL_FILES for the upgrade command, e.g. 174"make upgrade REMOVE_OPENSSL_FILES=yes" 175 17628-Oct-2016: openssl has been replaced by ressl. It is recommended that any 177stale OpenSSL files be removed to avoid configuration scripts from using 178the stale and potentially vulnerable version, but all binaries that are 179dynamically linked to the OpenSSL libraries should be rebuilt first to 180avoid breakage. 181 182OPENSSH HPN REMOVED 183------------------- 184 185It has become too cumbersome to maintain HPN patches in OpenSSH in base. 186To use OpenSSH in base remove HPN config, if you have added it. 187Check files below for HPN config, see a few lines below. 188 /etc/ssh/ssh_config, /etc/ssh/sshd_config, ~/.ssh/config 189sshd(8) will fail to start if HPN config is used. 190 191NOTE: HPN config in sshd_config will prohibit remote access to host using ssh. 192 193HPN config: 194HPNDisabled 195HPNBufferSize 196TcpRcvBuf 197TcpRcvBufPoll 198NoneEnabled 199NoneSwitch 200cipher MTR-AES-CTR 201cipher NONE 202 203OpenSSH HPN is a patch set to OpenSSH providing higher performance under some 204circumstances, especially for networking. 205If HPN functionality is needed, install security/openssh from dports. 206 207CS, EX AND VX DRIVERS REMOVED 208----------------------------- 209 210The cs(4), ex(4) and vx(4) drivers have been removed. They were very 211old and its doubtful they ever worked properly in x86_64 but they were 212in X86_64_GENERIC, so custom configurations derived from it have to be 213adjusted. 214 215+-----------------------------------------------------------------------+ 216+ UPGRADING DRAGONFLY FROM 4.4 TO LATER VERSIONS + 217+-----------------------------------------------------------------------+ 218 219AMD REMOVED 220----------- 221 222The am-utils automounter suite has been removed. It stopped working 223at some point and was never fixed. autofs(5) and the associated 224userland has been brought in from FreeBSD and replaces it. 225 226AN DRIVER REMOVED 227----------------- 228 229The an(4) driver has been removed. It was in the X86_64_GENERIC kernel 230config file, so any configurations derived from it have to be adjusted. 231 232/DEV/DRI GROUP CHANGED 233---------------------- 234 235The default group assigned to /dev/dri entries has been changed 236from 'wheel' to 'video' with the id of '44'. If you want to have 237access to the dri devices please add yourself to the video group 238with: 239 240# pw groupmod video -m $USER 241 242+-----------------------------------------------------------------------+ 243+ UPGRADING DRAGONFLY FROM 4.2 TO LATER VERSIONS + 244+-----------------------------------------------------------------------+ 245 246DSCHED REMOVED 247-------------- 248 249dsched(4) has been removed and one of its kernel options, DSCHED_FQ, was 250in our default kernel config file. So the DSCHED_FQ option has been turned 251into a no-op for now and can be removed from custom configurations. 252 253EST DRIVER REMOVED, COMPILE_ET AND LIBCOM_ERR TOO 254------------------------------------------------- 255 256The est(4) driver has been removed. All CPUs it supported (except one) 257were 32 bits only. Those who are still using the Core 2 Duo T7500 should 258report back if there are any issues with this CPU and our regular ACPI 259P-state support. 260 261Also, compile_et(1) and com_err(3) have been removed as well. They 262should have been removed along with kerberos support, back in 2009. 263 264SEVERAL LOCALES RENAMED 265----------------------- 266 267Several locales were using obsolete and misleading names, and thus have 268been adjusted to current standards. Any users of the following locales 269need to select alternates: 270 271DFLY 4.2 locale DFLY 4.4 alterative locale 272--------------- ------------------------------------ 273mn_MN.UTF-8 mn_Cyrl_MN.UTF-8 274no_NO.UTF-8 nb_NO.UTF-8 or nn_NO.UTF-8 275no_NO.ISO8859-1 nb_NO.ISO8869-1 or nn_NO.ISO8859-1 276no_NO.ISO8859-15 nb_NO.ISO8859-15 or nn_NO.ISO8859-15 277sr_YU.UTF-8 sr_Cyrl_RS.UTF-8 or sr_Latn_RS.UTF-8 278sr_YU.ISO8859-5 sr_Cyrl_RS.ISO8859-5 279sr_YU.ISO8859-2 sr_Latn_RS.ISO8859-2 280zh_CN.GBK zh_Hans_CN.GBK 281zh_CN.UTF-8 zh_Hans_CN.UTF-8 282zh_CN.eucCN zh_Hans_CN.eucCN 283zh_CN.GB2312 zh_Hans_CH.GB2312 284zh_CN.GB18030 zh_Hans_CH.GB18030 285zh_HK.Big5HKSCS zh_Hant_HK.Big5HKSCS 286zh_HK.UTF_8 zh_Hant_HK.UTF-8 287zh_TW.Big5 zh_Hant_TW.Big5 288zh_TW.UTF-8 zh_Hant_TW.UTF-8 289 290+-----------------------------------------------------------------------+ 291+ UPGRADING DRAGONFLY FROM 4.0 TO LATER VERSIONS + 292+-----------------------------------------------------------------------+ 293 294BINUTILS 2.25 REPLACES 2.22, PRIMARY 295------------------------------------ 296 297The oldest of the two versions of Binutils, version 2.22, was removed 298and replaced with Binutils 2.25. It becomes the primary version version 299of binutils and version 2.24 becomes the alternate. There are 8 current 300CVE written against 2.24, so for security reasons version 2.25 should 301always be used. 302 303The accepted values of BINUTILSVER are now "binutils225" (default) and 304"binutils224". The building of Binutils 2.24 can be prevented by setting 305NO_ALTBINUTILS=yes in make.conf. 306 307LOADER OPTIONS CHANGED 308---------------------- 309 310Right after the development branch started, the Fred art accompanying the 311loader menu was improved. The line between Fred and the menu was removed 312by default (but can optionally be returned) and the placement shifted as 313a result. The drawing was improved, and the colored version was improved, 314changing the eyes and wing color from white to red. A new color version 315of Fred was added, one with a blue scheme. 316 317The loader menu defaults have changed since release 4.0: The vertical 318line was removed, the loader is displayed in color by default*, and the 319blue scheme is used. 320 321The loader.conf changes are: 322loader_color: option has been removed 323loader_plain: option has been added, it changed menu to monochrome 324fred_is_red: changes color scheme from blue to red 325fred_is_blue: option existed only on 4.1, it has been removed 326fred_separated: Adds line between Fred and menu (as seen previously) 327 328* If loader.conf defines "console" as "comconsole" or "console" is defined 329 in the environment as "comconsole" then color will not be displayed, 330 even if loader_plain value is "NO". 331 332SENDMAIL REMOVED FROM BASE 333-------------------------- 334 335The only Mail Transfer Agent provided now is DragonFly Mail Agent (dma). 336If the system being upgraded is still configured to use the sendmail 337binaries from base, the "make upgrade" command will fail. 338 339The administrator must change /etc/mail/mailer.conf to switch the 340mailwrapper to dma or a DPorts-based MTA prior to running the upgrade 341command that permanently removes sendmail executables and could 342potentially break a running mail server. 343 344Refer: http://www.dragonflybsd.com/docs/docs/newhandbook/mta/ for 345detailed instructions on how to configure the MTA selection. 346 347_KPOSIX_VERSION and P1003_1B OPTIONS REMOVED 348-------------------------------------------- 349 350The _KPOSIX_VERSION and P1003_1B kernel options have been changed to 351no-ops. They can be removed from custom kernel configurations. 352 353SOUND SYSTEM UPDATED FROM FreeBSD 11-CURRENT 354-------------------------------------------- 355 356Many more sound devices may be detected. 357 358If the default device choosen isn't to your liking, setting the sysctl 359hw.snd.default_unit to a different number will change it. 360 361SCTP SUPPORT DROPPED 362-------------------- 363 364Support for the SCTP protocol has been removed. 365 366OLD USB DRIVERS REMOVED 367----------------------- 368 369The old USB stack, along with the kernel config option "device oldusb" 370and the make.conf variable "WANT_OLDUSB" have been removed. This means 371that for custom kernel configuration files which were derived from a 372GENERIC or X86_64_GENERIC file prior to making the usb4bsd stack default, 373various (old USB stack specific) devices will now complain about being 374unknown: 375 376 * oldusb (obviously) 377 * natausb (not yet ported to usb4bsd) 378 * rue (not yet ported to usb4bsd) 379 * ugen (no longer needed in usb4bsd) 380 * urio (not yet ported to usb4bsd) 381 * uscanner (no longer needed in usb4bsd) 382 383They should be removed or commented out in such custom kernel configs. 384 385GCC 5 386----- 387 388The GCC 4.4 compiler has been retired. It has been replaced by a GCC 5.1. 389The following make.conf variables no longer work: NO_GCC44, NO_OBJC, and 390NO_CXX. The latter was never documented and the latest versions of GCC are 391partially written in C++ so a C++ compiler is no longer optional. In 392practical terms it has not been optional for many years as other base 393components are also written in C++. The resource savings by avoiding 394building Objective-C compiler is so small, the complexity added by NO_OBJC 395internally was deemed a bad tradeoff so that is the reason for its removal. 396Also note that no "info" pages are installed with GCC 5. After this entry 397was originally written, all info pages were removed from DragonFly. 398 399GCC 5.1 has been designated as the primary compiler. As such, there is a 400new make.conf variable, NO_ALTCOMPILER. It will block the rebuilding of 401the designated secondary compiler, GCC 4.7. However, while DPorts 402primarily uses GCC 5 to build ports now, it still uses GCC 4.7 as well, so 403if building ports from source is desired, don't block building of the 404secondary compiler. 405 406+-----------------------------------------------------------------------+ 407+ UPGRADING DRAGONFLY FROM 3.8 TO LATER VERSIONS + 408+-----------------------------------------------------------------------+ 409 410SMP AND DEVICE_POLLING OPTIONS MADE UNKNOWN 411------------------------------------------- 412 413DEVICE_POLLING was replaced by IFPOLL_ENABLE and the former SMP code is 414the default now (even on single-core systems), both for, like, 21 months. 415We kept the options around as no-ops as a convenience, to allow people 416using the same config for the then current release and the then current 417master. That period is now over, so any configs still having those 418options have to be adjusted. 419 420SYSVIPC SYSCALLS MADE NON-OPTIONAL 421---------------------------------- 422 423The code related to the SYSVMSG, SYSVSEM and SYSVSHM kernel options is 424now compiled in by default. The options are no-ops for now. 425 426DEFAULT DRIVER CHANGED FOR LSI "THUNDERBOLT" SERIES RAID CONTROLLERS 427-------------------------------------------------------------------- 428 429The default driver for those controllers is now mrsas(4) due to reports 430of file system corruption using the mfi(4) driver. The whole issue (and 431how to deal with potential problems when switching) was explained here: 432 433http://lists.dragonflybsd.org/pipermail/users/2014-July/128703.html 434 435A tunable is provided for letting those controllers still attach via 436the mfi(4) driver, hw.mrsas.mfi_enable (see mrsas(4) manual page). 437 438OLDER NETWORK DRIVERS MOVED TO I386 ONLY 439---------------------------------------- 440 441The following drivers have been made i386 only: ed(4), sr(4), ng_sync_ar 442and ng_sync_sr. ed(4) used to be in X86_64_GENERIC, so it has to be 443removed in kernel configs derived from X86_64_GENERIC. 444 445+-----------------------------------------------------------------------+ 446+ UPGRADING DRAGONFLY FROM 3.6 TO LATER VERSIONS + 447+-----------------------------------------------------------------------+ 448 449UPDATE FROM MOST RECENT 3.6 450--------------------------- 451 452Versions of 3.6 built before June 25th have a bug where installworld might 453crash during installation of the new initrd. Upgrade to the latest version 454of 3.6 before updating to 3.8 or later. 455 456ATM, IPX, NCP AND NWFS SUPPORT DROPPED 457-------------------------------------- 458 459Support for the IPX and NCP network protocols and for mouting NetWare 460file systems has been dropped. Dito for ATM protocol support. 461 462INITRD IMAGES NOW INSTALLED BY DEFAULT 463-------------------------------------- 464 465An initial ramdisk image is now installed in /boot/kernel/initrd.img.gz 466 467Older images installed under the file name of initrd.img will be removed 468automatically by the make upgrade process. 469 470USB4BSD IS NOW THE DEFAULT USB STACK 471------------------------------------ 472 473To get back to the old stack, put "WANT_OLDUSB=yes" in /etc/make.conf and 474replace "device usb" with "device oldusb" in the kernel configuration. 475 476MORE ISA SUPPORT DROPPED 477------------------------ 478 479ISA support has been dropped from the following drivers: adv(4), an(4), 480ar(4), cs(4), digi(4), ed(4), ep(4), ex(4), fe(4), lnc(4), sbni(4), 481si(4), sn(4), and stg(4). 482 483+-----------------------------------------------------------------------+ 484+ UPGRADING DRAGONFLY FROM 3.4 TO LATER VERSIONS + 485+-----------------------------------------------------------------------+ 486 487ABI CHANGE 488---------- 489 490Installed third-party software (dports) will have to be rebuilt after upgrade, 491or reinstalled from binary packages. 492 493UPDATING FROM 3.4 TO 3.6 494------------------------ 495 496This only applies for this specific upgrade due to locale changes; it is 497not needed for upgrades after 3.6. Please update in this order: 498 499make buildworld 500make buildkernel 501make installworld 502make installkernel 503*reboot* 504make upgrade 505 506See this mailing list post for details: 507http://lists.dragonflybsd.org/pipermail/users/2013-September/090163.html 508 509CYRIX OPTIONS REMOVED 510--------------------- 511 512The following Cyrix related options have been removed: CPU_BTB_EN, 513CPU_CYRIX_NO_LOCK, CPU_DIRECT_MAPPED_CACHE, CPU_DISABLE_5X86_LSSER, 514CPU_FASTER_5X86_FPU, CPU_IORT, CPU_LOOP_EN, CPU_RSTK_EN, CPU_SUSP_HLT, 515CYRIX_CACHE_WORKS, and CYRIX_CACHE_REALLY_WORKS 516 517ISA SUPPORT REMOVED FROM RP(4) 518------------------------------ 519 520ISA support has been removed from the rp(4) driver. It is now PCI only. 521 522+-----------------------------------------------------------------------+ 523+ UPGRADING DRAGONFLY FROM 3.2 TO LATER VERSIONS + 524+-----------------------------------------------------------------------+ 525 526COMPAT_SUNOS OPTION REMOVED 527--------------------------- 528 529The COMPAT_SUNOS option has been removed. It was meant to provide binary 530compatibility with SunOS 4.x for the sparc32 port of 4.4BSD. 531 532ISA SOUND CARD SUPPORT REMOVED 533------------------------------ 534 535The following modules have been removed (all for ISA sound cards): 536snd_ad1816.ko, snd_ess.ko, snd_mss.ko, snd_sb8.ko, snd_sb16.ko, snd_sbc.ko 537 538GCC 4.7 539------- 540 541DragonFly has switched base compilers. GCC 4.7 is now the default 542compiler and GCC 4.4 is the alternative compiler. The "NO_GCC47" make 543variable ceases to work now. 544 545Users who wish to build only GCC 4.7 have to use NO_GCC44 in the 546/etc/make.conf to prohibit GCC 4.4 from building. However, using it is 547highly discouraged. There are a few packages in pkgsrc that do not build 548with GCC 4.7 and the new "DPorts" system uses GCC 4.4 by default. At 549this time, it is recommended to keep both compilers on the base system. 550 551SMP OPTION REMOVED 552------------------ 553 554The SMP kernel option has been made a no-op. All kernels now feature SMP 555support. If you have 'options SMP' in your kernel config, you can as well 556remove it. 557 558DEVICE_POLLING OPTION REPLACED BY IFPOLL_ENABLE OPTION, KTR_POLLING REMOVED 559--------------------------------------------------------------------------- 560 561The DEVICE_POLLING kernel option has been made a no-op and it has been 562replaced by IFPOLL_ENABLE. If you have 'options DEVICE_POLLING' in your 563kernel config, you need to change it to IFPOLL_ENABLE. 564 565Also, the KTR_POLLING kernel option has been removed, so it must be 566removed from kernel configs that have it. 567 568BUSLOGIC, CYCLADES AND STALLION ISA SUPPORT REMOVED 569--------------------------------------------------- 570 571The bt(4) driver for Buslogic SCSI adapters has been made PCI only. ISA 572cards will no longer be detected. 573 574The same has been done for Stallion multiport serial controllers. stli(4) 575has been completely removed (along with the stlload(8) and stlstty(8) 576utilities) and stl(4) was changed to support only PCI cards. Similarly, 577ISA support was removed from cy(4) too. All these drivers are i386 only. 578 579COMPAT_OLDISA OPTION GONE 580------------------------- 581 582The i386 specific COMPAT_OLDISA kernel option has been removed, since 583nothing needs it anymore. 584 585+-----------------------------------------------------------------------+ 586+ UPGRADING DRAGONFLY FROM 3.0 TO LATER VERSIONS + 587+-----------------------------------------------------------------------+ 588 589APIC_IO OPTION REMOVED 590---------------------- 591 592The APIC_IO kernel option is no longer accepted after having been without 593effect for a while. The hw.ioapic_enable tunable now serves its purpose. 594If you have 'options APIC_IO' in your kernel config, you'll have to 595remove it. 596 597WATCHDOG_ENABLE & HW_WDOG OPTIONS REMOVED 598----------------------------------------- 599 600The wdog framework is now compiled into our kernels by default, so the 601options are no longer needed. 602 603DOSCMD(1) REMOVED 604----------------- 605 606doscmd(1) has been removed. It was i386 only. The doscmd(1) specific 607NO_X make.conf option was removed too. 608 609GCC 4.7 610------- 611 612GCC 4.7 has been brought in and replaces GCC 4.1 as DragonFly's non- 613default compiler in base (default is still GCC 4.4). 614 615Users who wish to build only GCC 4.4 have to replace NO_GCC41 with 616NO_GCC47 in /etc/make.conf. 617 618USB4BSD 619------- 620 621A new USB stack (from FreeBSD) has been brought in. The following 622modules have been ported so far: usb, uhci, ohci, ehci, xhci, umass, 623usfs, uether, if_axe, if_udav, ukbd, ums, uep, uhid, usb_quirk, 624and uaudio. 625 626It is not yet the default. To activate it, WANT_USB4BSD=yes has to 627be put in make.conf and device "usb4bsd" (quotes needed) has to 628replace device usb in the kernel config. After that, a full 629build/install/upgrade cycle is needed. 630 631Note that this is experimental and incomplete, but we are interested 632in hearing about issues with it, of course. 633 634ISA SUPPORT REMOVED FROM AIC-6260/6360 DRIVER 635--------------------------------------------- 636 637ISA adapter support was dropped from the aic(4) driver. 638 639+-----------------------------------------------------------------------+ 640+ UPGRADING DRAGONFLY FROM 2.10 TO LATER VERSIONS + 641+-----------------------------------------------------------------------+ 642 643SEVERAL ISA DRIVERS REMOVED 644--------------------------- 645 646The following ISA only drivers have been removed along with a couple of 647associated userland tools: 648 649aha(4) 650asc(4) & sasc(1) 651ctx 652dgb(4) 653el(4) 654gpib 655gsc(4) & sgsc(1) 656ie(4) 657labpc(4) 658le(4) 659mse(4) 660rc(4) 661rdp(4) 662spigot 663tw(4) & xten(1) & xtend(8) 664wl(4) & wlconfig(8) 665wt(4) 666 667Note that two of these drivers (aha(4) and ie(4)) are in our GENERIC 668config and one (aha(4)) is in our X86_64_GENERIC kernel configuration 669file. 670 671If buildkernel complains about any of these drivers, just remove them 672from your kernel configuration. 673 674BINUTILS 2.20 675------------- 676Binutils 2.20 has been removed in favor of Binutils 2.22. The accepted 677values of BINUTILSVERS are now binutils221 and binutils222 (default). 678 679BUILDWORLD/-KERNEL PARALLELIZATION WORK 680--------------------------------------- 681Due to changes in the way we build with more than one make job, you 682will have to update install(1) and mkdir(1) prior to buildworld if you 683want to build with 'make -j': 684 685cd /usr/src/usr.bin/xinstall; make; make install; make clean 686cd /usr/src/bin/mkdir; make; make install; make clean 687 688DMA(8) UPGRADE 689-------------- 690dma(8) has been upgraded to v0.7 which no longer supports the 691/etc/dma/virtusertable. Some of its functionality has been replaced 692with the MASQUERADE keyword and the EMAIL environment variable (see 693the dma(8) manual page). 694 695+-----------------------------------------------------------------------+ 696+ UPGRADING DRAGONFLY FROM 2.8 TO LATER VERSIONS + 697+-----------------------------------------------------------------------+ 698 699GCC 4.4 & BINUTILS 2.21 700----------------------- 701 702GCC 4.4 has been made DragonFly's default compiler and Binutils 2.21 has 703been made DragonFly's default Binutils. 704 705That means that any settings that set CCVER to 'gcc44' are not needed 706anymore. Instead, CCVER can be set to 'gcc41' to go back to using 707GCC 4.1. 708 709It also means that 'binutils221' as a value for BINUTILSVER has no 710effect anymore. 2.17 has been removed and 'binutils220' is available 711as an option. 712 713The NO_GCC44 option has been removed and will not affect the build 714anymore. There is now a NO_GCC41 option that will prevent GCC 4.1 from 715building in a similar fashion. 716 717Note that you must do a full buildworld/buildkernel for upgrading. 718 719pkg_radd settings 720----------------- 721 722The config file for pkg_radd has moved from /etc/settings.conf to 723/etc/pkg_radd.conf. Save the contents of settings.conf before upgrading 724if this is needed. This warning only applies if /etc/settings.conf 725exists. pkg_radd will continue to work with defaults. 726 727+-----------------------------------------------------------------------+ 728+ 20100927 + 729+ UPGRADING DRAGONFLY FROM 2.6 to 2.8 or HEAD + 730+-----------------------------------------------------------------------+ 731 732OpenSSL 733-------- 734 735OpenSSL has been upgraded, and SHLIB_MAJOR was bumped for libssh and libcrypto. 736This shouldn't break any 3rd-party software, but you'll need to recompile your 7373rd-party software if you want it to link against the new version of OpenSSL. 738 739Loader 740------- 741 742A new loader (dloader) has been added which better handles booting from 743multiple kernel/module versions. 744 745To upgrade (Only for this upgrade, for post 2.8 upgrades see GENERAL below) 746 747 cd /usr/src 748 make buildworld 749 make installworld 750 make upgrade 751 make buildkernel KERNCONF=<KERNELNAME> 752 make installkernel KERNCONF=<KERNELNAME> 753 754Note that you must installworld and run the 'upgrade' target before 755installing the new kernel. 756 757BIND 758----- 759 760BIND has been removed from the base system. The ldns and drill tools have 761been added for basic functionality. Use 'drill' where you would normally 762use nslookup or dig, or install BIND from pkgsrc. It's available as 763net/bind95, net/bind96, or net/bind97 as of this writing. 764 765This only affects older systems upgrading to 2.8. New 2.8+ installs 766include BIND as a pkgsrc package. 767 768+-----------------------------------------------------------------------+ 769+ UPGRADING DRAGONFLY ON AN EXISTING DRAGONFLY SYSTEM + 770+ GENERAL + 771+-----------------------------------------------------------------------+ 772 773Instructions on how to obtain and maintain DragonFly source code using git 774are in the development(7) manual page. 775 776To upgrade a DragonFly system from sources you run the following sequence: 777 778 cd /usr/src 779 make buildworld 780 make buildkernel KERNCONF=<KERNELNAME> 781 make installkernel KERNCONF=<KERNELNAME> 782 make installworld 783 784You will also want to run the 'upgrade' target to upgrade your /etc and the 785rest of your system. The upgrade target is aware of stale files created by 786older DragonFly installations and should delete them automatically. 787 788 make upgrade 789 790See the build(7) manual page for further information. 791 792Once you've done a full build of the world and kernel you can do incremental 793upgrades of either by using the 'quickworld' and 'quickkernel' targets 794instead of 'buildworld' and 'buildkernel'. If you have any problems with 795the quick targets, try updating your repo first, and then a full buildworld 796and buildkernel as shown above, before asking for help. 797 798+-----------------------------------------------------------------------+ 799+ UPGRADING FROM DRAGONFLY <= 2.0 TO DRAGONFLY >= 2.1 + 800+-----------------------------------------------------------------------+ 801 802In 2.1 kernel and modules has moved to boot directory. For most cases 803this is handled automatically by 'make upgrade'. A few cases needs manual 804intervention: 805 806 * When installing a kernel without first doing a make buildworld, 807 installworld and upgrade to the same DESTDIR as kernel: 808 make DESTDIR/boot directory and move kernel and modules into this boot 809 directory; also move kernel.old and modules.old. 810 Typical example is vkernel(7), use (no modules used): 811 812 cd /var/vkernel 813 mkdir boot 814 chflags noschg kernel 815 mv kernel kernel.old boot 816 chflags schg boot/kernel 817 818 * When using a boot-only partition, /boot/loader.rc needs to be edited: 819 delete occurrences of '/boot/'. 820 These occurences can normally be deleted in any case, see loader(8). 821 822+-----------------------------------------------------------------------+ 823+ UPGRADING FROM DRAGONFLY <= 1.8 TO DRAGONFLY >= 1.9 + 824+-----------------------------------------------------------------------+ 825 826In 1.9 major changes to the disk management infrastructure have taken 827place. make upgrade may not catch all of your disk devices in /dev, 828so after upgrading be sure to cd /dev; ./MAKEDEV <blah> where <blah> 829are all of your disk devices. HOWEVER, from late 2.3 on we run devfs 830and MAKEDEV no longer exists. 831 832The biggest changes in 1.9 are: 833 834(1) That whole-slice devices such as da0s1 no longer share the same device 835 id as partition c devices such as da0s1c. 836 837(2) The whole-disk device (e.g. da0) is full raw access to the disk, 838 with no snooping or reserved sectors. Consequently you cannot run 839 disklabel on this device. Instead you must run disklabel on a 840 whole-slice device. 841 842(3) The 'compatibility' partitions now use slice 0 in the device name, 843 so instead of da0a you must specify da0s0a. Also, as per (1) above, 844 accessing the disklabel for the compatibility partitions must be 845 done via slice 0 (da0s0). 846 847(4) Many device drivers that used to fake up labels, such as CD, ACD, VN, 848 and CCD now run through the disk management layer and are assigned 849 real disk management devices. VN and CCD in particular do not usually 850 use a MBR and disklabels must be accessed through the compatibility 851 slice 0. Your /etc/ccd.conf file still specifies 'ccd0', though, you 852 don't name it 'ccd0s0' in the config file. 853 854Generally speaking, you have to get used to running fdisk and disklabel on 855the correctly specified device names. A lot of the wiggle, such as running 856disklabel on a partition, has been removed. 857 858+-----------------------------------------------------------------------+ 859+ UPGRADING FROM OLDER VERSIONS OF DRAGONFLY OR FREEBSD + 860+-----------------------------------------------------------------------+ 861 862> Kerberos IV 863------------- 864 865Kerberos IV (eBones) was removed from the tree, please consider moving to 866Kerberos 5 (Heimdal). 867 868> Package Management System 869--------------------------- 870 871Starting with the 1.4 release, DragonFly uses NetBSD's pkgsrc package 872management system. The necessary tools to build and maintain packages 873are provided in /usr/pkg/bin and /usr/pkg/sbin. Make sure that these 874directories are in your PATH variable. 875 876In order to obtain a reasonably current snapshot of the pkgsrc tree, use 877the tarball from NetBSD: 878 879 fetch -o /tmp/pkgsrc.tar.gz ftp://ftp.NetBSD.org/pub/NetBSD/packages/pkgsrc.tar.gz 880 cd /usr; tar -xzf /tmp/pkgsrc.tar.gz; chown -R root:wheel pkgsrc 881 882This tree can then be kept up to date with cvs update: 883 884 cd /usr/pkgsrc; cvs up 885 886NOTE! If you upgraded from a pre-1.4 system to 1.4 or later, you need to 887build and install the pkgsrc bootstrap manually: 888 889 cd /usr/pkgsrc/bootstrap 890 ./bootstrap --pkgdbdir /var/db/pkg --prefix /usr/pkg 891 892+-----------------------------------------------------------------------+ 893+ UPGRADING DRAGONFLY ON AN EXISTING DRAGONFLY SYSTEM + 894+ UPDATING FROM PRE-1.2 SYSTEMS OR FreeBSD 4.x TO + 895+ DRAGONFLY 1.3+ (EITHER PREVIEW or HEAD) + 896+-----------------------------------------------------------------------+ 897 898The compatibility shims for the build environment have been removed, you 899have to update to DragonFly 1.2 release branch first. 900 901The default PAM configuration has moved from /etc/pam.conf to /etc/pam.d/. 902The existing configuration can be converted using /etc/pam.d/convert.sh. 903Entries in /etc/pam.d/ override entries in /etc/pam.conf. In addition 904the pam_skey.so module was retired, you have to remove it manually from 905your configuration, when you convert it. 906 907> Required user and group IDs when upgrading from either FreeBSD or DragonFly 908--------------------- 909 910The following users may be missing from your password file. Use vipw and 911add any that are missing: 912 913smmsp:*:25:25::0:0:Sendmail Submission User:/var/spool/clientmqueue:/sbin/nologin 914_pflogd:*:64:64::0:0:pflogd privsep user:/var/empty:/sbin/nologin 915 916The following groups may be missing from your group file. Use vi /etc/group 917and add any that are missing: 918 919smmsp:*:25: 920authpf:*:63: 921_pflogd:*:64: 922 923 924> Upgrading to DragonFly from FreeBSD 925--------------------- 926 927You can build the DragonFly world and DragonFly kernels on a FreeBSD-4.x or 928FreeBSD-5.x machine and then install DragonFly over FreeBSD, replacing 929FreeBSD. Note that the DragonFly buildworld target does not try to reuse 930make depend information, it starts from scratch, so no pre-cleaning of the 931object hierarchy is necessary. 932 933 # get the CVS repository (it is placed in /home/dcvs, 500MB). 934 # Please use the -h option and a mirror site to pull the 935 # initial repository, but feel free to use the main repository 936 # machine to pull updates. 937 cvsup /usr/share/examples/cvsup/DragonFly-cvs-supfile 938 # install the source from the CVS hierarchy (remove preexisting 939 # FreeBSD src first) (500MB) 940 cd /usr 941 rm -rf src 942 cvs -R -d /home/dcvs checkout -P src 943 944 # build it (500MB used in /usr/obj) 945 # 946 cd /usr/src 947 make buildworld 948 make buildkernel KERNCONF=<KERNELNAME> 949 950Once you have built DragonFly you have to install it over FreeBSD. Since 951DragonFly does not track changes made by FreeBSD to its include file 952hierarchy and include file pollution can cause all sorts of unexpected 953compilation issues to come up, it is best to wipe your include hierarchy 954prior to installing DragonFly. Note that you should not wipe any installed 955FreeBSD header files or binaries until after you have successfully completed 956the build steps above. 957 958 rm -rf /usr/include 959 mkdir /usr/include 960 make installkernel KERNCONF=<KERNELNAME> 961 make installworld 962 963Then you need to upgrade your system. DragonFly's 'make upgrade' target 964will unconditionally upgrade the /etc files that sysops do not usually 965mess around with, such as the files in /etc/rc.d. It will also remove any 966obsolete files such as utilities and manpages that have been removed from 967the system since the version you're coming from. If you are unsure we 968recommend that you make a backup of at least your /etc before applying 969this step. Note that DragonFly's RC system is basically RCNG from 970FreeBSD-5, but there are some differences in the contents of the RC files. 971 972 make upgrade 973 974NOTE! Never do a 'make upgrade' before 'make installworld' has been run. 975Doing so might leave your system in an unusable state. 976 977Finally we recommend that you do an 'ls -lta BLAH' for /bin, /sbin, /usr/bin, 978/usr/bin, and /usr/lib, and remove any stale files that you find. Please 979report these files to the DragonFly developers so that they can be added to 980the 'upgrade' target. 981 982
