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 15TIMED AND TIMEDC REMOVED 16------------------------ 17 18timed(8) and timedc(8) have been removed because they are beyond 19obsolete for setting the time. 20 21LIBOPIE, LIBMD REMOVED 22---------------------- 23 24Removal of OPIE requires /etc/pam.d/ configs to be updated. 25 26+-----------------------------------------------------------------------+ 27+ UPGRADING DRAGONFLY FROM 5.4 TO LATER VERSIONS + 28+-----------------------------------------------------------------------+ 29 30GCC50 REMOVED 31------------- 32 33The GCC50 compiler has been retired. It has been replaced by a GCC80. 34The default alternative compiler has stayed the same - GCC47. 35 36 37PUFFS, PUTTER AND LIBREFUSE REMOVED 38----------------------------------- 39 40The puffs(4)/putter(4) subsystem has been removed, along with librefuse, 41libpuffs, and the mount_psshfs(8) utility. All of these have never been 42working correctly. 43 44FFS_ROOT OPTION REMOVED 45----------------------- 46 47The FFS_ROOT kernel configuration option has been finally removed, after 48having been a no-op since 4.9. That means users using a custom kernel 49configuration file that still contains it need to remove the option from 50that file. 51 52+-----------------------------------------------------------------------+ 53+ UPGRADING DRAGONFLY FROM 5.2 TO LATER VERSIONS + 54+-----------------------------------------------------------------------+ 55 56DIGI, RP AND SI DRIVERS REMOVED 57------------------------------- 58 59The digi(4), rp(4) and si(4) serial drivers have been removed. None of 60them were in our default kernel configuration file. The sicontrol(8) 61utility was removed, too. 62 63MKINITRD COMMAND REMOVED 64------------------------ 65 66The mkinitrd(8) command is removed and its functionality is replaced by 67the new "initrd" make target. After rebooting into the new world and 68verifying everything works, execute "make initrd" to upgrade the rescue 69tools and initrd image. 70 71IPSEC, IPSEC_ESP AND IPSEC_DEBUG REMOVED FROM VKERNEL64 CONFIG 72-------------------------------------------------------------- 73 74IPsec has been removed from the system. Of our standard kernel 75configurations, only the virtual kernel one had it. People running 76vkernels with configuration files derived from our VKERNEL64 will 77have to remove these options manually. 78 79+-----------------------------------------------------------------------+ 80+ UPGRADING DRAGONFLY FROM 5.0 TO LATER VERSIONS + 81+-----------------------------------------------------------------------+ 82 83VIRTIO_PCI REMOVED FROM KERNEL CONFIG 84------------------------------------- 85 86The "device virtio_pci" line in X86_64_GENERIC has been removed. People 87with configuration files derived from it have to remove it manually. 88 89VARIOUS 'R' COMMANDS AND DAEMONS REMOVED 90---------------------------------------- 91 92rcp(1), rlogin(1), rlogind(8), rsh(1) and rshd(8) have been removed. 93For those that still need them, there is the net/bsdrcmds port. 94 95VARIOUS FORMER OPTIONS REMOVED 96------------------------------ 97 98Various former kernel configuration options which had been no-ops for 99some time were completely removed: SYSVMSG, SYSVSEM, SYSVSHM, P1003_1B, 100_KPOSIX_VERSION and DSCHED_FQ. Users that have any of these still in 101their kernel configuration files have to remove them. 102 103BOOTSTRAPPING LIMITED FROM PRE 4.4 104---------------------------------- 105 106Upgrading to 5.1 and later versions now require at least 4.4 in 107preparations for upcoming base compilers updates. 108 109IF_PPP, PPPD, IF_FAITH, AND FAITHD REMOVED 110------------------------------------------ 111 112if_ppp has been replaced by "user ppp", i.e. ppp(8) and tun(4). It had 113already been removed from our default kernel configuration before 5.0, 114so only people with custom configurations based on earlier X86_64_GENERIC 115will have to remove it manually. 116 117The faith(4) interface has been completely removed after it had also 118been removed from our default kernel configuration. 119 120+-----------------------------------------------------------------------+ 121+ UPGRADING DRAGONFLY FROM 4.8 TO LATER VERSIONS + 122+-----------------------------------------------------------------------+ 123 124FFS_ROOT OPTION DISABLED 125------------------------ 126 127The FFS_ROOT option has been made a no-op and will be completely removed 128at some point in the future. Users with a custom kernel configuration 129can remove this option from it now. 130 131+-----------------------------------------------------------------------+ 132+ UPGRADING DRAGONFLY FROM 4.6 TO LATER VERSIONS + 133+-----------------------------------------------------------------------+ 134 135DSA OPENSSH KEYS DEPRECATED 136--------------------------- 137 138Note that DSA OpenSSH keys were deprecated in the 4.6 to 4.8 release. 139If you are upgrading from a release older than 4.8 and use DSA OpenSSH 140keys, please update your private/public key pair or risk locking 141yourself out. 142 143AHC, AHD, AIC, NCV, NSP AND STG DRIVERS REMOVED 144----------------------------------------------- 145 146They were all in our X86_64_GENERIC kernel configuration file, along with 147the AHC_REG_PRETTY_PRINT and AHD_REG_PRETTY_PRINT options, so any custom 148configuration files derived from it need adjustment. 149 150PORTAL FILE SYSTEM REMOVED 151-------------------------- 152 153It has been broken for a long time now. 154 155BINUTILS 2.27 REPLACES 2.24, PRIMARY 156------------------------------------ 157 158The oldest of the two versions of Binutils, version 2.24, was removed 159and replaced with Binutils 2.27. It becomes the primary version version 160of binutils and version 2.25 becomes the alternate. 161 162The accepted values of BINUTILSVER are now "binutils227" (default) and 163"binutils225". The building of Binutils 2.25 can be prevented by setting 164NO_ALTBINUTILS=yes in make.conf. 165 166COMPAT_43 KERNEL OPTION REMOVED 167------------------------------- 168 169It was commented out in our default configs for several years now, but 170might still be present in custom configs created before Nov. 2011. 171 172OPENSSL REMOVED 173--------------- 174 175OpenSSL has been removed from base and replaced with a private version of 176LibreSSL. The previously installed OpenSSL libraries, headers, and man 177pages will remain on the system unless the "make upgrade" command is 178specifically instructed to remove them. To do this, define 179REMOVE_OPENSSL_FILES for the upgrade command, e.g. 180"make upgrade REMOVE_OPENSSL_FILES=yes" 181 18228-Oct-2016: openssl has been replaced by ressl. It is recommended that any 183stale OpenSSL files be removed to avoid configuration scripts from using 184the stale and potentially vulnerable version, but all binaries that are 185dynamically linked to the OpenSSL libraries should be rebuilt first to 186avoid breakage. 187 188OPENSSH HPN REMOVED 189------------------- 190 191It has become too cumbersome to maintain HPN patches in OpenSSH in base. 192To use OpenSSH in base remove HPN config, if you have added it. 193Check files below for HPN config, see a few lines below. 194 /etc/ssh/ssh_config, /etc/ssh/sshd_config, ~/.ssh/config 195sshd(8) will fail to start if HPN config is used. 196 197NOTE: HPN config in sshd_config will prohibit remote access to host using ssh. 198 199HPN config: 200HPNDisabled 201HPNBufferSize 202TcpRcvBuf 203TcpRcvBufPoll 204NoneEnabled 205NoneSwitch 206cipher MTR-AES-CTR 207cipher NONE 208 209OpenSSH HPN is a patch set to OpenSSH providing higher performance under some 210circumstances, especially for networking. 211If HPN functionality is needed, install security/openssh from dports. 212 213CS, EX AND VX DRIVERS REMOVED 214----------------------------- 215 216The cs(4), ex(4) and vx(4) drivers have been removed. They were very 217old and its doubtful they ever worked properly in x86_64 but they were 218in X86_64_GENERIC, so custom configurations derived from it have to be 219adjusted. 220 221+-----------------------------------------------------------------------+ 222+ UPGRADING DRAGONFLY FROM 4.4 TO LATER VERSIONS + 223+-----------------------------------------------------------------------+ 224 225AMD REMOVED 226----------- 227 228The am-utils automounter suite has been removed. It stopped working 229at some point and was never fixed. autofs(5) and the associated 230userland has been brought in from FreeBSD and replaces it. 231 232AN DRIVER REMOVED 233----------------- 234 235The an(4) driver has been removed. It was in the X86_64_GENERIC kernel 236config file, so any configurations derived from it have to be adjusted. 237 238/DEV/DRI GROUP CHANGED 239---------------------- 240 241The default group assigned to /dev/dri entries has been changed 242from 'wheel' to 'video' with the id of '44'. If you want to have 243access to the dri devices please add yourself to the video group 244with: 245 246# pw groupmod video -m $USER 247 248+-----------------------------------------------------------------------+ 249+ UPGRADING DRAGONFLY FROM 4.2 TO LATER VERSIONS + 250+-----------------------------------------------------------------------+ 251 252DSCHED REMOVED 253-------------- 254 255dsched(4) has been removed and one of its kernel options, DSCHED_FQ, was 256in our default kernel config file. So the DSCHED_FQ option has been turned 257into a no-op for now and can be removed from custom configurations. 258 259EST DRIVER REMOVED, COMPILE_ET AND LIBCOM_ERR TOO 260------------------------------------------------- 261 262The est(4) driver has been removed. All CPUs it supported (except one) 263were 32 bits only. Those who are still using the Core 2 Duo T7500 should 264report back if there are any issues with this CPU and our regular ACPI 265P-state support. 266 267Also, compile_et(1) and com_err(3) have been removed as well. They 268should have been removed along with kerberos support, back in 2009. 269 270SEVERAL LOCALES RENAMED 271----------------------- 272 273Several locales were using obsolete and misleading names, and thus have 274been adjusted to current standards. Any users of the following locales 275need to select alternates: 276 277DFLY 4.2 locale DFLY 4.4 alterative locale 278--------------- ------------------------------------ 279mn_MN.UTF-8 mn_Cyrl_MN.UTF-8 280no_NO.UTF-8 nb_NO.UTF-8 or nn_NO.UTF-8 281no_NO.ISO8859-1 nb_NO.ISO8869-1 or nn_NO.ISO8859-1 282no_NO.ISO8859-15 nb_NO.ISO8859-15 or nn_NO.ISO8859-15 283sr_YU.UTF-8 sr_Cyrl_RS.UTF-8 or sr_Latn_RS.UTF-8 284sr_YU.ISO8859-5 sr_Cyrl_RS.ISO8859-5 285sr_YU.ISO8859-2 sr_Latn_RS.ISO8859-2 286zh_CN.GBK zh_Hans_CN.GBK 287zh_CN.UTF-8 zh_Hans_CN.UTF-8 288zh_CN.eucCN zh_Hans_CN.eucCN 289zh_CN.GB2312 zh_Hans_CH.GB2312 290zh_CN.GB18030 zh_Hans_CH.GB18030 291zh_HK.Big5HKSCS zh_Hant_HK.Big5HKSCS 292zh_HK.UTF_8 zh_Hant_HK.UTF-8 293zh_TW.Big5 zh_Hant_TW.Big5 294zh_TW.UTF-8 zh_Hant_TW.UTF-8 295 296+-----------------------------------------------------------------------+ 297+ UPGRADING DRAGONFLY FROM 4.0 TO LATER VERSIONS + 298+-----------------------------------------------------------------------+ 299 300BINUTILS 2.25 REPLACES 2.22, PRIMARY 301------------------------------------ 302 303The oldest of the two versions of Binutils, version 2.22, was removed 304and replaced with Binutils 2.25. It becomes the primary version version 305of binutils and version 2.24 becomes the alternate. There are 8 current 306CVE written against 2.24, so for security reasons version 2.25 should 307always be used. 308 309The accepted values of BINUTILSVER are now "binutils225" (default) and 310"binutils224". The building of Binutils 2.24 can be prevented by setting 311NO_ALTBINUTILS=yes in make.conf. 312 313LOADER OPTIONS CHANGED 314---------------------- 315 316Right after the development branch started, the Fred art accompanying the 317loader menu was improved. The line between Fred and the menu was removed 318by default (but can optionally be returned) and the placement shifted as 319a result. The drawing was improved, and the colored version was improved, 320changing the eyes and wing color from white to red. A new color version 321of Fred was added, one with a blue scheme. 322 323The loader menu defaults have changed since release 4.0: The vertical 324line was removed, the loader is displayed in color by default*, and the 325blue scheme is used. 326 327The loader.conf changes are: 328loader_color: option has been removed 329loader_plain: option has been added, it changed menu to monochrome 330fred_is_red: changes color scheme from blue to red 331fred_is_blue: option existed only on 4.1, it has been removed 332fred_separated: Adds line between Fred and menu (as seen previously) 333 334* If loader.conf defines "console" as "comconsole" or "console" is defined 335 in the environment as "comconsole" then color will not be displayed, 336 even if loader_plain value is "NO". 337 338SENDMAIL REMOVED FROM BASE 339-------------------------- 340 341The only Mail Transfer Agent provided now is DragonFly Mail Agent (dma). 342If the system being upgraded is still configured to use the sendmail 343binaries from base, the "make upgrade" command will fail. 344 345The administrator must change /etc/mail/mailer.conf to switch the 346mailwrapper to dma or a DPorts-based MTA prior to running the upgrade 347command that permanently removes sendmail executables and could 348potentially break a running mail server. 349 350Refer: http://www.dragonflybsd.com/docs/docs/newhandbook/mta/ for 351detailed instructions on how to configure the MTA selection. 352 353_KPOSIX_VERSION and P1003_1B OPTIONS REMOVED 354-------------------------------------------- 355 356The _KPOSIX_VERSION and P1003_1B kernel options have been changed to 357no-ops. They can be removed from custom kernel configurations. 358 359SOUND SYSTEM UPDATED FROM FreeBSD 11-CURRENT 360-------------------------------------------- 361 362Many more sound devices may be detected. 363 364If the default device choosen isn't to your liking, setting the sysctl 365hw.snd.default_unit to a different number will change it. 366 367SCTP SUPPORT DROPPED 368-------------------- 369 370Support for the SCTP protocol has been removed. 371 372OLD USB DRIVERS REMOVED 373----------------------- 374 375The old USB stack, along with the kernel config option "device oldusb" 376and the make.conf variable "WANT_OLDUSB" have been removed. This means 377that for custom kernel configuration files which were derived from a 378GENERIC or X86_64_GENERIC file prior to making the usb4bsd stack default, 379various (old USB stack specific) devices will now complain about being 380unknown: 381 382 * oldusb (obviously) 383 * natausb (not yet ported to usb4bsd) 384 * rue (not yet ported to usb4bsd) 385 * ugen (no longer needed in usb4bsd) 386 * urio (not yet ported to usb4bsd) 387 * uscanner (no longer needed in usb4bsd) 388 389They should be removed or commented out in such custom kernel configs. 390 391GCC 5 392----- 393 394The GCC 4.4 compiler has been retired. It has been replaced by a GCC 5.1. 395The following make.conf variables no longer work: NO_GCC44, NO_OBJC, and 396NO_CXX. The latter was never documented and the latest versions of GCC are 397partially written in C++ so a C++ compiler is no longer optional. In 398practical terms it has not been optional for many years as other base 399components are also written in C++. The resource savings by avoiding 400building Objective-C compiler is so small, the complexity added by NO_OBJC 401internally was deemed a bad tradeoff so that is the reason for its removal. 402Also note that no "info" pages are installed with GCC 5. After this entry 403was originally written, all info pages were removed from DragonFly. 404 405GCC 5.1 has been designated as the primary compiler. As such, there is a 406new make.conf variable, NO_ALTCOMPILER. It will block the rebuilding of 407the designated secondary compiler, GCC 4.7. However, while DPorts 408primarily uses GCC 5 to build ports now, it still uses GCC 4.7 as well, so 409if building ports from source is desired, don't block building of the 410secondary compiler. 411 412+-----------------------------------------------------------------------+ 413+ UPGRADING DRAGONFLY FROM 3.8 TO LATER VERSIONS + 414+-----------------------------------------------------------------------+ 415 416SMP AND DEVICE_POLLING OPTIONS MADE UNKNOWN 417------------------------------------------- 418 419DEVICE_POLLING was replaced by IFPOLL_ENABLE and the former SMP code is 420the default now (even on single-core systems), both for, like, 21 months. 421We kept the options around as no-ops as a convenience, to allow people 422using the same config for the then current release and the then current 423master. That period is now over, so any configs still having those 424options have to be adjusted. 425 426SYSVIPC SYSCALLS MADE NON-OPTIONAL 427---------------------------------- 428 429The code related to the SYSVMSG, SYSVSEM and SYSVSHM kernel options is 430now compiled in by default. The options are no-ops for now. 431 432DEFAULT DRIVER CHANGED FOR LSI "THUNDERBOLT" SERIES RAID CONTROLLERS 433-------------------------------------------------------------------- 434 435The default driver for those controllers is now mrsas(4) due to reports 436of file system corruption using the mfi(4) driver. The whole issue (and 437how to deal with potential problems when switching) was explained here: 438 439http://lists.dragonflybsd.org/pipermail/users/2014-July/128703.html 440 441A tunable is provided for letting those controllers still attach via 442the mfi(4) driver, hw.mrsas.mfi_enable (see mrsas(4) manual page). 443 444OLDER NETWORK DRIVERS MOVED TO I386 ONLY 445---------------------------------------- 446 447The following drivers have been made i386 only: ed(4), sr(4), ng_sync_ar 448and ng_sync_sr. ed(4) used to be in X86_64_GENERIC, so it has to be 449removed in kernel configs derived from X86_64_GENERIC. 450 451+-----------------------------------------------------------------------+ 452+ UPGRADING DRAGONFLY FROM 3.6 TO LATER VERSIONS + 453+-----------------------------------------------------------------------+ 454 455UPDATE FROM MOST RECENT 3.6 456--------------------------- 457 458Versions of 3.6 built before June 25th have a bug where installworld might 459crash during installation of the new initrd. Upgrade to the latest version 460of 3.6 before updating to 3.8 or later. 461 462ATM, IPX, NCP AND NWFS SUPPORT DROPPED 463-------------------------------------- 464 465Support for the IPX and NCP network protocols and for mouting NetWare 466file systems has been dropped. Dito for ATM protocol support. 467 468INITRD IMAGES NOW INSTALLED BY DEFAULT 469-------------------------------------- 470 471An initial ramdisk image is now installed in /boot/kernel/initrd.img.gz 472 473Older images installed under the file name of initrd.img will be removed 474automatically by the make upgrade process. 475 476USB4BSD IS NOW THE DEFAULT USB STACK 477------------------------------------ 478 479To get back to the old stack, put "WANT_OLDUSB=yes" in /etc/make.conf and 480replace "device usb" with "device oldusb" in the kernel configuration. 481 482MORE ISA SUPPORT DROPPED 483------------------------ 484 485ISA support has been dropped from the following drivers: adv(4), an(4), 486ar(4), cs(4), digi(4), ed(4), ep(4), ex(4), fe(4), lnc(4), sbni(4), 487si(4), sn(4), and stg(4). 488 489+-----------------------------------------------------------------------+ 490+ UPGRADING DRAGONFLY FROM 3.4 TO LATER VERSIONS + 491+-----------------------------------------------------------------------+ 492 493ABI CHANGE 494---------- 495 496Installed third-party software (dports) will have to be rebuilt after upgrade, 497or reinstalled from binary packages. 498 499UPDATING FROM 3.4 TO 3.6 500------------------------ 501 502This only applies for this specific upgrade due to locale changes; it is 503not needed for upgrades after 3.6. Please update in this order: 504 505make buildworld 506make buildkernel 507make installworld 508make installkernel 509*reboot* 510make upgrade 511 512See this mailing list post for details: 513http://lists.dragonflybsd.org/pipermail/users/2013-September/090163.html 514 515CYRIX OPTIONS REMOVED 516--------------------- 517 518The following Cyrix related options have been removed: CPU_BTB_EN, 519CPU_CYRIX_NO_LOCK, CPU_DIRECT_MAPPED_CACHE, CPU_DISABLE_5X86_LSSER, 520CPU_FASTER_5X86_FPU, CPU_IORT, CPU_LOOP_EN, CPU_RSTK_EN, CPU_SUSP_HLT, 521CYRIX_CACHE_WORKS, and CYRIX_CACHE_REALLY_WORKS 522 523ISA SUPPORT REMOVED FROM RP(4) 524------------------------------ 525 526ISA support has been removed from the rp(4) driver. It is now PCI only. 527 528+-----------------------------------------------------------------------+ 529+ UPGRADING DRAGONFLY FROM 3.2 TO LATER VERSIONS + 530+-----------------------------------------------------------------------+ 531 532COMPAT_SUNOS OPTION REMOVED 533--------------------------- 534 535The COMPAT_SUNOS option has been removed. It was meant to provide binary 536compatibility with SunOS 4.x for the sparc32 port of 4.4BSD. 537 538ISA SOUND CARD SUPPORT REMOVED 539------------------------------ 540 541The following modules have been removed (all for ISA sound cards): 542snd_ad1816.ko, snd_ess.ko, snd_mss.ko, snd_sb8.ko, snd_sb16.ko, snd_sbc.ko 543 544GCC 4.7 545------- 546 547DragonFly has switched base compilers. GCC 4.7 is now the default 548compiler and GCC 4.4 is the alternative compiler. The "NO_GCC47" make 549variable ceases to work now. 550 551Users who wish to build only GCC 4.7 have to use NO_GCC44 in the 552/etc/make.conf to prohibit GCC 4.4 from building. However, using it is 553highly discouraged. There are a few packages in pkgsrc that do not build 554with GCC 4.7 and the new "DPorts" system uses GCC 4.4 by default. At 555this time, it is recommended to keep both compilers on the base system. 556 557SMP OPTION REMOVED 558------------------ 559 560The SMP kernel option has been made a no-op. All kernels now feature SMP 561support. If you have 'options SMP' in your kernel config, you can as well 562remove it. 563 564DEVICE_POLLING OPTION REPLACED BY IFPOLL_ENABLE OPTION, KTR_POLLING REMOVED 565--------------------------------------------------------------------------- 566 567The DEVICE_POLLING kernel option has been made a no-op and it has been 568replaced by IFPOLL_ENABLE. If you have 'options DEVICE_POLLING' in your 569kernel config, you need to change it to IFPOLL_ENABLE. 570 571Also, the KTR_POLLING kernel option has been removed, so it must be 572removed from kernel configs that have it. 573 574BUSLOGIC, CYCLADES AND STALLION ISA SUPPORT REMOVED 575--------------------------------------------------- 576 577The bt(4) driver for Buslogic SCSI adapters has been made PCI only. ISA 578cards will no longer be detected. 579 580The same has been done for Stallion multiport serial controllers. stli(4) 581has been completely removed (along with the stlload(8) and stlstty(8) 582utilities) and stl(4) was changed to support only PCI cards. Similarly, 583ISA support was removed from cy(4) too. All these drivers are i386 only. 584 585COMPAT_OLDISA OPTION GONE 586------------------------- 587 588The i386 specific COMPAT_OLDISA kernel option has been removed, since 589nothing needs it anymore. 590 591+-----------------------------------------------------------------------+ 592+ UPGRADING DRAGONFLY FROM 3.0 TO LATER VERSIONS + 593+-----------------------------------------------------------------------+ 594 595APIC_IO OPTION REMOVED 596---------------------- 597 598The APIC_IO kernel option is no longer accepted after having been without 599effect for a while. The hw.ioapic_enable tunable now serves its purpose. 600If you have 'options APIC_IO' in your kernel config, you'll have to 601remove it. 602 603WATCHDOG_ENABLE & HW_WDOG OPTIONS REMOVED 604----------------------------------------- 605 606The wdog framework is now compiled into our kernels by default, so the 607options are no longer needed. 608 609DOSCMD(1) REMOVED 610----------------- 611 612doscmd(1) has been removed. It was i386 only. The doscmd(1) specific 613NO_X make.conf option was removed too. 614 615GCC 4.7 616------- 617 618GCC 4.7 has been brought in and replaces GCC 4.1 as DragonFly's non- 619default compiler in base (default is still GCC 4.4). 620 621Users who wish to build only GCC 4.4 have to replace NO_GCC41 with 622NO_GCC47 in /etc/make.conf. 623 624USB4BSD 625------- 626 627A new USB stack (from FreeBSD) has been brought in. The following 628modules have been ported so far: usb, uhci, ohci, ehci, xhci, umass, 629usfs, uether, if_axe, if_udav, ukbd, ums, uep, uhid, usb_quirk, 630and uaudio. 631 632It is not yet the default. To activate it, WANT_USB4BSD=yes has to 633be put in make.conf and device "usb4bsd" (quotes needed) has to 634replace device usb in the kernel config. After that, a full 635build/install/upgrade cycle is needed. 636 637Note that this is experimental and incomplete, but we are interested 638in hearing about issues with it, of course. 639 640ISA SUPPORT REMOVED FROM AIC-6260/6360 DRIVER 641--------------------------------------------- 642 643ISA adapter support was dropped from the aic(4) driver. 644 645+-----------------------------------------------------------------------+ 646+ UPGRADING DRAGONFLY FROM 2.10 TO LATER VERSIONS + 647+-----------------------------------------------------------------------+ 648 649SEVERAL ISA DRIVERS REMOVED 650--------------------------- 651 652The following ISA only drivers have been removed along with a couple of 653associated userland tools: 654 655aha(4) 656asc(4) & sasc(1) 657ctx 658dgb(4) 659el(4) 660gpib 661gsc(4) & sgsc(1) 662ie(4) 663labpc(4) 664le(4) 665mse(4) 666rc(4) 667rdp(4) 668spigot 669tw(4) & xten(1) & xtend(8) 670wl(4) & wlconfig(8) 671wt(4) 672 673Note that two of these drivers (aha(4) and ie(4)) are in our GENERIC 674config and one (aha(4)) is in our X86_64_GENERIC kernel configuration 675file. 676 677If buildkernel complains about any of these drivers, just remove them 678from your kernel configuration. 679 680BINUTILS 2.20 681------------- 682Binutils 2.20 has been removed in favor of Binutils 2.22. The accepted 683values of BINUTILSVERS are now binutils221 and binutils222 (default). 684 685BUILDWORLD/-KERNEL PARALLELIZATION WORK 686--------------------------------------- 687Due to changes in the way we build with more than one make job, you 688will have to update install(1) and mkdir(1) prior to buildworld if you 689want to build with 'make -j': 690 691cd /usr/src/usr.bin/xinstall; make; make install; make clean 692cd /usr/src/bin/mkdir; make; make install; make clean 693 694DMA(8) UPGRADE 695-------------- 696dma(8) has been upgraded to v0.7 which no longer supports the 697/etc/dma/virtusertable. Some of its functionality has been replaced 698with the MASQUERADE keyword and the EMAIL environment variable (see 699the dma(8) manual page). 700 701+-----------------------------------------------------------------------+ 702+ UPGRADING DRAGONFLY FROM 2.8 TO LATER VERSIONS + 703+-----------------------------------------------------------------------+ 704 705GCC 4.4 & BINUTILS 2.21 706----------------------- 707 708GCC 4.4 has been made DragonFly's default compiler and Binutils 2.21 has 709been made DragonFly's default Binutils. 710 711That means that any settings that set CCVER to 'gcc44' are not needed 712anymore. Instead, CCVER can be set to 'gcc41' to go back to using 713GCC 4.1. 714 715It also means that 'binutils221' as a value for BINUTILSVER has no 716effect anymore. 2.17 has been removed and 'binutils220' is available 717as an option. 718 719The NO_GCC44 option has been removed and will not affect the build 720anymore. There is now a NO_GCC41 option that will prevent GCC 4.1 from 721building in a similar fashion. 722 723Note that you must do a full buildworld/buildkernel for upgrading. 724 725pkg_radd settings 726----------------- 727 728The config file for pkg_radd has moved from /etc/settings.conf to 729/etc/pkg_radd.conf. Save the contents of settings.conf before upgrading 730if this is needed. This warning only applies if /etc/settings.conf 731exists. pkg_radd will continue to work with defaults. 732 733+-----------------------------------------------------------------------+ 734+ 20100927 + 735+ UPGRADING DRAGONFLY FROM 2.6 to 2.8 or HEAD + 736+-----------------------------------------------------------------------+ 737 738OpenSSL 739-------- 740 741OpenSSL has been upgraded, and SHLIB_MAJOR was bumped for libssh and libcrypto. 742This shouldn't break any 3rd-party software, but you'll need to recompile your 7433rd-party software if you want it to link against the new version of OpenSSL. 744 745Loader 746------- 747 748A new loader (dloader) has been added which better handles booting from 749multiple kernel/module versions. 750 751To upgrade (Only for this upgrade, for post 2.8 upgrades see GENERAL below) 752 753 cd /usr/src 754 make buildworld 755 make installworld 756 make upgrade 757 make buildkernel KERNCONF=<KERNELNAME> 758 make installkernel KERNCONF=<KERNELNAME> 759 760Note that you must installworld and run the 'upgrade' target before 761installing the new kernel. 762 763BIND 764----- 765 766BIND has been removed from the base system. The ldns and drill tools have 767been added for basic functionality. Use 'drill' where you would normally 768use nslookup or dig, or install BIND from pkgsrc. It's available as 769net/bind95, net/bind96, or net/bind97 as of this writing. 770 771This only affects older systems upgrading to 2.8. New 2.8+ installs 772include BIND as a pkgsrc package. 773 774+-----------------------------------------------------------------------+ 775+ UPGRADING DRAGONFLY ON AN EXISTING DRAGONFLY SYSTEM + 776+ GENERAL + 777+-----------------------------------------------------------------------+ 778 779Instructions on how to obtain and maintain DragonFly source code using git 780are in the development(7) manual page. 781 782To upgrade a DragonFly system from sources you run the following sequence: 783 784 cd /usr/src 785 make buildworld 786 make buildkernel KERNCONF=<KERNELNAME> 787 make installkernel KERNCONF=<KERNELNAME> 788 make installworld 789 790You will also want to run the 'upgrade' target to upgrade your /etc and the 791rest of your system. The upgrade target is aware of stale files created by 792older DragonFly installations and should delete them automatically. 793 794 make upgrade 795 796See the build(7) manual page for further information. 797 798Once you've done a full build of the world and kernel you can do incremental 799upgrades of either by using the 'quickworld' and 'quickkernel' targets 800instead of 'buildworld' and 'buildkernel'. If you have any problems with 801the quick targets, try updating your repo first, and then a full buildworld 802and buildkernel as shown above, before asking for help. 803 804+-----------------------------------------------------------------------+ 805+ UPGRADING FROM DRAGONFLY <= 2.0 TO DRAGONFLY >= 2.1 + 806+-----------------------------------------------------------------------+ 807 808In 2.1 kernel and modules has moved to boot directory. For most cases 809this is handled automatically by 'make upgrade'. A few cases needs manual 810intervention: 811 812 * When installing a kernel without first doing a make buildworld, 813 installworld and upgrade to the same DESTDIR as kernel: 814 make DESTDIR/boot directory and move kernel and modules into this boot 815 directory; also move kernel.old and modules.old. 816 Typical example is vkernel(7), use (no modules used): 817 818 cd /var/vkernel 819 mkdir boot 820 chflags noschg kernel 821 mv kernel kernel.old boot 822 chflags schg boot/kernel 823 824 * When using a boot-only partition, /boot/loader.rc needs to be edited: 825 delete occurrences of '/boot/'. 826 These occurences can normally be deleted in any case, see loader(8). 827 828+-----------------------------------------------------------------------+ 829+ UPGRADING FROM DRAGONFLY <= 1.8 TO DRAGONFLY >= 1.9 + 830+-----------------------------------------------------------------------+ 831 832In 1.9 major changes to the disk management infrastructure have taken 833place. make upgrade may not catch all of your disk devices in /dev, 834so after upgrading be sure to cd /dev; ./MAKEDEV <blah> where <blah> 835are all of your disk devices. HOWEVER, from late 2.3 on we run devfs 836and MAKEDEV no longer exists. 837 838The biggest changes in 1.9 are: 839 840(1) That whole-slice devices such as da0s1 no longer share the same device 841 id as partition c devices such as da0s1c. 842 843(2) The whole-disk device (e.g. da0) is full raw access to the disk, 844 with no snooping or reserved sectors. Consequently you cannot run 845 disklabel on this device. Instead you must run disklabel on a 846 whole-slice device. 847 848(3) The 'compatibility' partitions now use slice 0 in the device name, 849 so instead of da0a you must specify da0s0a. Also, as per (1) above, 850 accessing the disklabel for the compatibility partitions must be 851 done via slice 0 (da0s0). 852 853(4) Many device drivers that used to fake up labels, such as CD, ACD, VN, 854 and CCD now run through the disk management layer and are assigned 855 real disk management devices. VN and CCD in particular do not usually 856 use a MBR and disklabels must be accessed through the compatibility 857 slice 0. Your /etc/ccd.conf file still specifies 'ccd0', though, you 858 don't name it 'ccd0s0' in the config file. 859 860Generally speaking, you have to get used to running fdisk and disklabel on 861the correctly specified device names. A lot of the wiggle, such as running 862disklabel on a partition, has been removed. 863 864+-----------------------------------------------------------------------+ 865+ UPGRADING FROM OLDER VERSIONS OF DRAGONFLY OR FREEBSD + 866+-----------------------------------------------------------------------+ 867 868> Kerberos IV 869------------- 870 871Kerberos IV (eBones) was removed from the tree, please consider moving to 872Kerberos 5 (Heimdal). 873 874> Package Management System 875--------------------------- 876 877Starting with the 1.4 release, DragonFly uses NetBSD's pkgsrc package 878management system. The necessary tools to build and maintain packages 879are provided in /usr/pkg/bin and /usr/pkg/sbin. Make sure that these 880directories are in your PATH variable. 881 882In order to obtain a reasonably current snapshot of the pkgsrc tree, use 883the tarball from NetBSD: 884 885 fetch -o /tmp/pkgsrc.tar.gz ftp://ftp.NetBSD.org/pub/NetBSD/packages/pkgsrc.tar.gz 886 cd /usr; tar -xzf /tmp/pkgsrc.tar.gz; chown -R root:wheel pkgsrc 887 888This tree can then be kept up to date with cvs update: 889 890 cd /usr/pkgsrc; cvs up 891 892NOTE! If you upgraded from a pre-1.4 system to 1.4 or later, you need to 893build and install the pkgsrc bootstrap manually: 894 895 cd /usr/pkgsrc/bootstrap 896 ./bootstrap --pkgdbdir /var/db/pkg --prefix /usr/pkg 897 898+-----------------------------------------------------------------------+ 899+ UPGRADING DRAGONFLY ON AN EXISTING DRAGONFLY SYSTEM + 900+ UPDATING FROM PRE-1.2 SYSTEMS OR FreeBSD 4.x TO + 901+ DRAGONFLY 1.3+ (EITHER PREVIEW or HEAD) + 902+-----------------------------------------------------------------------+ 903 904The compatibility shims for the build environment have been removed, you 905have to update to DragonFly 1.2 release branch first. 906 907The default PAM configuration has moved from /etc/pam.conf to /etc/pam.d/. 908The existing configuration can be converted using /etc/pam.d/convert.sh. 909Entries in /etc/pam.d/ override entries in /etc/pam.conf. In addition 910the pam_skey.so module was retired, you have to remove it manually from 911your configuration, when you convert it. 912 913> Required user and group IDs when upgrading from either FreeBSD or DragonFly 914--------------------- 915 916The following users may be missing from your password file. Use vipw and 917add any that are missing: 918 919smmsp:*:25:25::0:0:Sendmail Submission User:/var/spool/clientmqueue:/sbin/nologin 920_pflogd:*:64:64::0:0:pflogd privsep user:/var/empty:/sbin/nologin 921 922The following groups may be missing from your group file. Use vi /etc/group 923and add any that are missing: 924 925smmsp:*:25: 926authpf:*:63: 927_pflogd:*:64: 928 929 930> Upgrading to DragonFly from FreeBSD 931--------------------- 932 933You can build the DragonFly world and DragonFly kernels on a FreeBSD-4.x or 934FreeBSD-5.x machine and then install DragonFly over FreeBSD, replacing 935FreeBSD. Note that the DragonFly buildworld target does not try to reuse 936make depend information, it starts from scratch, so no pre-cleaning of the 937object hierarchy is necessary. 938 939 # get the CVS repository (it is placed in /home/dcvs, 500MB). 940 # Please use the -h option and a mirror site to pull the 941 # initial repository, but feel free to use the main repository 942 # machine to pull updates. 943 cvsup /usr/share/examples/cvsup/DragonFly-cvs-supfile 944 # install the source from the CVS hierarchy (remove preexisting 945 # FreeBSD src first) (500MB) 946 cd /usr 947 rm -rf src 948 cvs -R -d /home/dcvs checkout -P src 949 950 # build it (500MB used in /usr/obj) 951 # 952 cd /usr/src 953 make buildworld 954 make buildkernel KERNCONF=<KERNELNAME> 955 956Once you have built DragonFly you have to install it over FreeBSD. Since 957DragonFly does not track changes made by FreeBSD to its include file 958hierarchy and include file pollution can cause all sorts of unexpected 959compilation issues to come up, it is best to wipe your include hierarchy 960prior to installing DragonFly. Note that you should not wipe any installed 961FreeBSD header files or binaries until after you have successfully completed 962the build steps above. 963 964 rm -rf /usr/include 965 mkdir /usr/include 966 make installkernel KERNCONF=<KERNELNAME> 967 make installworld 968 969Then you need to upgrade your system. DragonFly's 'make upgrade' target 970will unconditionally upgrade the /etc files that sysops do not usually 971mess around with, such as the files in /etc/rc.d. It will also remove any 972obsolete files such as utilities and manpages that have been removed from 973the system since the version you're coming from. If you are unsure we 974recommend that you make a backup of at least your /etc before applying 975this step. Note that DragonFly's RC system is basically RCNG from 976FreeBSD-5, but there are some differences in the contents of the RC files. 977 978 make upgrade 979 980NOTE! Never do a 'make upgrade' before 'make installworld' has been run. 981Doing so might leave your system in an unusable state. 982 983Finally we recommend that you do an 'ls -lta BLAH' for /bin, /sbin, /usr/bin, 984/usr/bin, and /usr/lib, and remove any stale files that you find. Please 985report these files to the DragonFly developers so that they can be added to 986the 'upgrade' target. 987 988
