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 5.2 TO LATER VERSIONS + 13+-----------------------------------------------------------------------+ 14 15DIGI, RP AND SI DRIVERS REMOVED 16------------------------------- 17 18The digi(4), rp(4) and si(4) serial drivers have been removed. None of 19them were in our default kernel configuration file. The sicontrol(8) 20utility was removed, too. 21 22MKINITRD COMMAND REMOVED 23------------------------ 24 25The mkinitrd(8) command is removed and its functionality is replaced by 26the new "initrd" make target. After rebooting into the new world and 27verifying everything works, execute "make initrd" to upgrade the rescue 28tools and initrd image. 29 30IPSEC, IPSEC_ESP AND IPSEC_DEBUG REMOVED FROM VKERNEL64 CONFIG 31-------------------------------------------------------------- 32 33IPsec has been removed from the system. Of our standard kernel 34configurations, only the virtual kernel one had it. People running 35vkernels with configuration files derived from our VKERNEL64 will 36have to remove these options manually. 37 38+-----------------------------------------------------------------------+ 39+ UPGRADING DRAGONFLY FROM 5.0 TO LATER VERSIONS + 40+-----------------------------------------------------------------------+ 41 42VIRTIO_PCI REMOVED FROM KERNEL CONFIG 43------------------------------------- 44 45The "device virtio_pci" line in X86_64_GENERIC has been removed. People 46with configuration files derived from it have to remove it manually. 47 48VARIOUS 'R' COMMANDS AND DAEMONS REMOVED 49---------------------------------------- 50 51rcp(1), rlogin(1), rlogind(8), rsh(1) and rshd(8) have been removed. 52For those that still need them, there is the net/bsdrcmds port. 53 54VARIOUS FORMER OPTIONS REMOVED 55------------------------------ 56 57Various former kernel configuration options which had been no-ops for 58some time were completely removed: SYSVMSG, SYSVSEM, SYSVSHM, P1003_1B, 59_KPOSIX_VERSION and DSCHED_FQ. Users that have any of these still in 60their kernel configuration files have to remove them. 61 62BOOTSTRAPPING LIMITED FROM PRE 4.4 63---------------------------------- 64 65Upgrading to 5.1 and later versions now require at least 4.4 in 66preparations for upcoming base compilers updates. 67 68IF_PPP, PPPD, IF_FAITH, AND FAITHD REMOVED 69------------------------------------------ 70 71if_ppp has been replaced by "user ppp", i.e. ppp(8) and tun(4). It had 72already been removed from our default kernel configuration before 5.0, 73so only people with custom configurations based on earlier X86_64_GENERIC 74will have to remove it manually. 75 76The faith(4) interface has been completely removed after it had also 77been removed from our default kernel configuration. 78 79+-----------------------------------------------------------------------+ 80+ UPGRADING DRAGONFLY FROM 4.8 TO LATER VERSIONS + 81+-----------------------------------------------------------------------+ 82 83FFS_ROOT OPTION DISABLED 84------------------------ 85 86The FFS_ROOT option has been made a no-op and will be completely removed 87at some point in the future. Users with a custom kernel configuration 88can remove this option from it now. 89 90+-----------------------------------------------------------------------+ 91+ UPGRADING DRAGONFLY FROM 4.6 TO LATER VERSIONS + 92+-----------------------------------------------------------------------+ 93 94AHC, AHD, AIC, NCV, NSP AND STG DRIVERS REMOVED 95----------------------------------------------- 96 97They were all in our X86_64_GENERIC kernel configuration file, along with 98the AHC_REG_PRETTY_PRINT and AHD_REG_PRETTY_PRINT options, so any custom 99configuration files derived from it need adjustment. 100 101PORTAL FILE SYSTEM REMOVED 102-------------------------- 103 104It has been broken for a long time now. 105 106BINUTILS 2.27 REPLACES 2.24, PRIMARY 107------------------------------------ 108 109The oldest of the two versions of Binutils, version 2.24, was removed 110and replaced with Binutils 2.27. It becomes the primary version version 111of binutils and version 2.25 becomes the alternate. 112 113The accepted values of BINUTILSVER are now "binutils227" (default) and 114"binutils225". The building of Binutils 2.25 can be prevented by setting 115NO_ALTBINUTILS=yes in make.conf. 116 117COMPAT_43 KERNEL OPTION REMOVED 118------------------------------- 119 120It was commented out in our default configs for several years now, but 121might still be present in custom configs created before Nov. 2011. 122 123OPENSSL REMOVED 124--------------- 125 126OpenSSL has been removed from base and replaced with a private version of 127LibreSSL. The previously installed OpenSSL libraries, headers, and man 128pages will remain on the system unless the "make upgrade" command is 129specifically instructed to remove them. To do this, define 130REMOVE_OPENSSL_FILES for the upgrade command, e.g. 131"make upgrade REMOVE_OPENSSL_FILES=yes" 132 13328-Oct-2016: openssl has been replaced by ressl. It is recommended that any 134stale OpenSSL files be removed to avoid configuration scripts from using 135the stale and potentially vulnerable version, but all binaries that are 136dynamically linked to the OpenSSL libraries should be rebuilt first to 137avoid breakage. 138 139OPENSSH HPN REMOVED 140------------------- 141 142It has become too cumbersome to maintain HPN patches in OpenSSH in base. 143To use OpenSSH in base remove HPN config, if you have added it. 144Check files below for HPN config, see a few lines below. 145 /etc/ssh/ssh_config, /etc/ssh/sshd_config, ~/.ssh/config 146sshd(8) will fail to start if HPN config is used. 147 148NOTE: HPN config in sshd_config will prohibit remote access to host using ssh. 149 150HPN config: 151HPNDisabled 152HPNBufferSize 153TcpRcvBuf 154TcpRcvBufPoll 155NoneEnabled 156NoneSwitch 157cipher MTR-AES-CTR 158cipher NONE 159 160OpenSSH HPN is a patch set to OpenSSH providing higher performance under some 161circumstances, especially for networking. 162If HPN functionality is needed, install security/openssh from dports. 163 164CS, EX AND VX DRIVERS REMOVED 165----------------------------- 166 167The cs(4), ex(4) and vx(4) drivers have been removed. They were very 168old and its doubtful they ever worked properly in x86_64 but they were 169in X86_64_GENERIC, so custom configurations derived from it have to be 170adjusted. 171 172+-----------------------------------------------------------------------+ 173+ UPGRADING DRAGONFLY FROM 4.4 TO LATER VERSIONS + 174+-----------------------------------------------------------------------+ 175 176AMD REMOVED 177----------- 178 179The am-utils automounter suite has been removed. It stopped working 180at some point and was never fixed. autofs(5) and the associated 181userland has been brought in from FreeBSD and replaces it. 182 183AN DRIVER REMOVED 184----------------- 185 186The an(4) driver has been removed. It was in the X86_64_GENERIC kernel 187config file, so any configurations derived from it have to be adjusted. 188 189/DEV/DRI GROUP CHANGED 190---------------------- 191 192The default group assigned to /dev/dri entries has been changed 193from 'wheel' to 'video' with the id of '44'. If you want to have 194access to the dri devices please add yourself to the video group 195with: 196 197# pw groupmod video -m $USER 198 199+-----------------------------------------------------------------------+ 200+ UPGRADING DRAGONFLY FROM 4.2 TO LATER VERSIONS + 201+-----------------------------------------------------------------------+ 202 203DSCHED REMOVED 204-------------- 205 206dsched(4) has been removed and one of its kernel options, DSCHED_FQ, was 207in our default kernel config file. So the DSCHED_FQ option has been turned 208into a no-op for now and can be removed from custom configurations. 209 210EST DRIVER REMOVED, COMPILE_ET AND LIBCOM_ERR TOO 211------------------------------------------------- 212 213The est(4) driver has been removed. All CPUs it supported (except one) 214were 32 bits only. Those who are still using the Core 2 Duo T7500 should 215report back if there are any issues with this CPU and our regular ACPI 216P-state support. 217 218Also, compile_et(1) and com_err(3) have been removed as well. They 219should have been removed along with kerberos support, back in 2009. 220 221SEVERAL LOCALES RENAMED 222----------------------- 223 224Several locales were using obsolete and misleading names, and thus have 225been adjusted to current standards. Any users of the following locales 226need to select alternates: 227 228DFLY 4.2 locale DFLY 4.4 alterative locale 229--------------- ------------------------------------ 230mn_MN.UTF-8 mn_Cyrl_MN.UTF-8 231no_NO.UTF-8 nb_NO.UTF-8 or nn_NO.UTF-8 232no_NO.ISO8859-1 nb_NO.ISO8869-1 or nn_NO.ISO8859-1 233no_NO.ISO8859-15 nb_NO.ISO8859-15 or nn_NO.ISO8859-15 234sr_YU.UTF-8 sr_Cyrl_RS.UTF-8 or sr_Latn_RS.UTF-8 235sr_YU.ISO8859-5 sr_Cyrl_RS.ISO8859-5 236sr_YU.ISO8859-2 sr_Latn_RS.ISO8859-2 237zh_CN.GBK zh_Hans_CN.GBK 238zh_CN.UTF-8 zh_Hans_CN.UTF-8 239zh_CN.eucCN zh_Hans_CN.eucCN 240zh_CN.GB2312 zh_Hans_CH.GB2312 241zh_CN.GB18030 zh_Hans_CH.GB18030 242zh_HK.Big5HKSCS zh_Hant_HK.Big5HKSCS 243zh_HK.UTF_8 zh_Hant_HK.UTF-8 244zh_TW.Big5 zh_Hant_TW.Big5 245zh_TW.UTF-8 zh_Hant_TW.UTF-8 246 247+-----------------------------------------------------------------------+ 248+ UPGRADING DRAGONFLY FROM 4.0 TO LATER VERSIONS + 249+-----------------------------------------------------------------------+ 250 251BINUTILS 2.25 REPLACES 2.22, PRIMARY 252------------------------------------ 253 254The oldest of the two versions of Binutils, version 2.22, was removed 255and replaced with Binutils 2.25. It becomes the primary version version 256of binutils and version 2.24 becomes the alternate. There are 8 current 257CVE written against 2.24, so for security reasons version 2.25 should 258always be used. 259 260The accepted values of BINUTILSVER are now "binutils225" (default) and 261"binutils224". The building of Binutils 2.24 can be prevented by setting 262NO_ALTBINUTILS=yes in make.conf. 263 264LOADER OPTIONS CHANGED 265---------------------- 266 267Right after the development branch started, the Fred art accompanying the 268loader menu was improved. The line between Fred and the menu was removed 269by default (but can optionally be returned) and the placement shifted as 270a result. The drawing was improved, and the colored version was improved, 271changing the eyes and wing color from white to red. A new color version 272of Fred was added, one with a blue scheme. 273 274The loader menu defaults have changed since release 4.0: The vertical 275line was removed, the loader is displayed in color by default*, and the 276blue scheme is used. 277 278The loader.conf changes are: 279loader_color: option has been removed 280loader_plain: option has been added, it changed menu to monochrome 281fred_is_red: changes color scheme from blue to red 282fred_is_blue: option existed only on 4.1, it has been removed 283fred_separated: Adds line between Fred and menu (as seen previously) 284 285* If loader.conf defines "console" as "comconsole" or "console" is defined 286 in the environment as "comconsole" then color will not be displayed, 287 even if loader_plain value is "NO". 288 289SENDMAIL REMOVED FROM BASE 290-------------------------- 291 292The only Mail Transfer Agent provided now is DragonFly Mail Agent (dma). 293If the system being upgraded is still configured to use the sendmail 294binaries from base, the "make upgrade" command will fail. 295 296The administrator must change /etc/mail/mailer.conf to switch the 297mailwrapper to dma or a DPorts-based MTA prior to running the upgrade 298command that permanently removes sendmail executables and could 299potentially break a running mail server. 300 301Refer: http://www.dragonflybsd.com/docs/docs/newhandbook/mta/ for 302detailed instructions on how to configure the MTA selection. 303 304_KPOSIX_VERSION and P1003_1B OPTIONS REMOVED 305-------------------------------------------- 306 307The _KPOSIX_VERSION and P1003_1B kernel options have been changed to 308no-ops. They can be removed from custom kernel configurations. 309 310SOUND SYSTEM UPDATED FROM FreeBSD 11-CURRENT 311-------------------------------------------- 312 313Many more sound devices may be detected. 314 315If the default device choosen isn't to your liking, setting the sysctl 316hw.snd.default_unit to a different number will change it. 317 318SCTP SUPPORT DROPPED 319-------------------- 320 321Support for the SCTP protocol has been removed. 322 323OLD USB DRIVERS REMOVED 324----------------------- 325 326The old USB stack, along with the kernel config option "device oldusb" 327and the make.conf variable "WANT_OLDUSB" have been removed. This means 328that for custom kernel configuration files which were derived from a 329GENERIC or X86_64_GENERIC file prior to making the usb4bsd stack default, 330various (old USB stack specific) devices will now complain about being 331unknown: 332 333 * oldusb (obviously) 334 * natausb (not yet ported to usb4bsd) 335 * rue (not yet ported to usb4bsd) 336 * ugen (no longer needed in usb4bsd) 337 * urio (not yet ported to usb4bsd) 338 * uscanner (no longer needed in usb4bsd) 339 340They should be removed or commented out in such custom kernel configs. 341 342GCC 5 343----- 344 345The GCC 4.4 compiler has been retired. It has been replaced by a GCC 5.1. 346The following make.conf variables no longer work: NO_GCC44, NO_OBJC, and 347NO_CXX. The latter was never documented and the latest versions of GCC are 348partially written in C++ so a C++ compiler is no longer optional. In 349practical terms it has not been optional for many years as other base 350components are also written in C++. The resource savings by avoiding 351building Objective-C compiler is so small, the complexity added by NO_OBJC 352internally was deemed a bad tradeoff so that is the reason for its removal. 353Also note that no "info" pages are installed with GCC 5. After this entry 354was originally written, all info pages were removed from DragonFly. 355 356GCC 5.1 has been designated as the primary compiler. As such, there is a 357new make.conf variable, NO_ALTCOMPILER. It will block the rebuilding of 358the designated secondary compiler, GCC 4.7. However, while DPorts 359primarily uses GCC 5 to build ports now, it still uses GCC 4.7 as well, so 360if building ports from source is desired, don't block building of the 361secondary compiler. 362 363+-----------------------------------------------------------------------+ 364+ UPGRADING DRAGONFLY FROM 3.8 TO LATER VERSIONS + 365+-----------------------------------------------------------------------+ 366 367SMP AND DEVICE_POLLING OPTIONS MADE UNKNOWN 368------------------------------------------- 369 370DEVICE_POLLING was replaced by IFPOLL_ENABLE and the former SMP code is 371the default now (even on single-core systems), both for, like, 21 months. 372We kept the options around as no-ops as a convenience, to allow people 373using the same config for the then current release and the then current 374master. That period is now over, so any configs still having those 375options have to be adjusted. 376 377SYSVIPC SYSCALLS MADE NON-OPTIONAL 378---------------------------------- 379 380The code related to the SYSVMSG, SYSVSEM and SYSVSHM kernel options is 381now compiled in by default. The options are no-ops for now. 382 383DEFAULT DRIVER CHANGED FOR LSI "THUNDERBOLT" SERIES RAID CONTROLLERS 384-------------------------------------------------------------------- 385 386The default driver for those controllers is now mrsas(4) due to reports 387of file system corruption using the mfi(4) driver. The whole issue (and 388how to deal with potential problems when switching) was explained here: 389 390http://lists.dragonflybsd.org/pipermail/users/2014-July/128703.html 391 392A tunable is provided for letting those controllers still attach via 393the mfi(4) driver, hw.mrsas.mfi_enable (see mrsas(4) manual page). 394 395OLDER NETWORK DRIVERS MOVED TO I386 ONLY 396---------------------------------------- 397 398The following drivers have been made i386 only: ed(4), sr(4), ng_sync_ar 399and ng_sync_sr. ed(4) used to be in X86_64_GENERIC, so it has to be 400removed in kernel configs derived from X86_64_GENERIC. 401 402+-----------------------------------------------------------------------+ 403+ UPGRADING DRAGONFLY FROM 3.6 TO LATER VERSIONS + 404+-----------------------------------------------------------------------+ 405 406UPDATE FROM MOST RECENT 3.6 407--------------------------- 408 409Versions of 3.6 built before June 25th have a bug where installworld might 410crash during installation of the new initrd. Upgrade to the latest version 411of 3.6 before updating to 3.8 or later. 412 413ATM, IPX, NCP AND NWFS SUPPORT DROPPED 414-------------------------------------- 415 416Support for the IPX and NCP network protocols and for mouting NetWare 417file systems has been dropped. Dito for ATM protocol support. 418 419INITRD IMAGES NOW INSTALLED BY DEFAULT 420-------------------------------------- 421 422An initial ramdisk image is now installed in /boot/kernel/initrd.img.gz 423 424Older images installed under the file name of initrd.img will be removed 425automatically by the make upgrade process. 426 427USB4BSD IS NOW THE DEFAULT USB STACK 428------------------------------------ 429 430To get back to the old stack, put "WANT_OLDUSB=yes" in /etc/make.conf and 431replace "device usb" with "device oldusb" in the kernel configuration. 432 433MORE ISA SUPPORT DROPPED 434------------------------ 435 436ISA support has been dropped from the following drivers: adv(4), an(4), 437ar(4), cs(4), digi(4), ed(4), ep(4), ex(4), fe(4), lnc(4), sbni(4), 438si(4), sn(4), and stg(4). 439 440+-----------------------------------------------------------------------+ 441+ UPGRADING DRAGONFLY FROM 3.4 TO LATER VERSIONS + 442+-----------------------------------------------------------------------+ 443 444ABI CHANGE 445---------- 446 447Installed third-party software (dports) will have to be rebuilt after upgrade, 448or reinstalled from binary packages. 449 450UPDATING FROM 3.4 TO 3.6 451------------------------ 452 453This only applies for this specific upgrade due to locale changes; it is 454not needed for upgrades after 3.6. Please update in this order: 455 456make buildworld 457make buildkernel 458make installworld 459make installkernel 460*reboot* 461make upgrade 462 463See this mailing list post for details: 464http://lists.dragonflybsd.org/pipermail/users/2013-September/090163.html 465 466CYRIX OPTIONS REMOVED 467--------------------- 468 469The following Cyrix related options have been removed: CPU_BTB_EN, 470CPU_CYRIX_NO_LOCK, CPU_DIRECT_MAPPED_CACHE, CPU_DISABLE_5X86_LSSER, 471CPU_FASTER_5X86_FPU, CPU_IORT, CPU_LOOP_EN, CPU_RSTK_EN, CPU_SUSP_HLT, 472CYRIX_CACHE_WORKS, and CYRIX_CACHE_REALLY_WORKS 473 474ISA SUPPORT REMOVED FROM RP(4) 475------------------------------ 476 477ISA support has been removed from the rp(4) driver. It is now PCI only. 478 479+-----------------------------------------------------------------------+ 480+ UPGRADING DRAGONFLY FROM 3.2 TO LATER VERSIONS + 481+-----------------------------------------------------------------------+ 482 483COMPAT_SUNOS OPTION REMOVED 484--------------------------- 485 486The COMPAT_SUNOS option has been removed. It was meant to provide binary 487compatibility with SunOS 4.x for the sparc32 port of 4.4BSD. 488 489ISA SOUND CARD SUPPORT REMOVED 490------------------------------ 491 492The following modules have been removed (all for ISA sound cards): 493snd_ad1816.ko, snd_ess.ko, snd_mss.ko, snd_sb8.ko, snd_sb16.ko, snd_sbc.ko 494 495GCC 4.7 496------- 497 498DragonFly has switched base compilers. GCC 4.7 is now the default 499compiler and GCC 4.4 is the alternative compiler. The "NO_GCC47" make 500variable ceases to work now. 501 502Users who wish to build only GCC 4.7 have to use NO_GCC44 in the 503/etc/make.conf to prohibit GCC 4.4 from building. However, using it is 504highly discouraged. There are a few packages in pkgsrc that do not build 505with GCC 4.7 and the new "DPorts" system uses GCC 4.4 by default. At 506this time, it is recommended to keep both compilers on the base system. 507 508SMP OPTION REMOVED 509------------------ 510 511The SMP kernel option has been made a no-op. All kernels now feature SMP 512support. If you have 'options SMP' in your kernel config, you can as well 513remove it. 514 515DEVICE_POLLING OPTION REPLACED BY IFPOLL_ENABLE OPTION, KTR_POLLING REMOVED 516--------------------------------------------------------------------------- 517 518The DEVICE_POLLING kernel option has been made a no-op and it has been 519replaced by IFPOLL_ENABLE. If you have 'options DEVICE_POLLING' in your 520kernel config, you need to change it to IFPOLL_ENABLE. 521 522Also, the KTR_POLLING kernel option has been removed, so it must be 523removed from kernel configs that have it. 524 525BUSLOGIC, CYCLADES AND STALLION ISA SUPPORT REMOVED 526--------------------------------------------------- 527 528The bt(4) driver for Buslogic SCSI adapters has been made PCI only. ISA 529cards will no longer be detected. 530 531The same has been done for Stallion multiport serial controllers. stli(4) 532has been completely removed (along with the stlload(8) and stlstty(8) 533utilities) and stl(4) was changed to support only PCI cards. Similarly, 534ISA support was removed from cy(4) too. All these drivers are i386 only. 535 536COMPAT_OLDISA OPTION GONE 537------------------------- 538 539The i386 specific COMPAT_OLDISA kernel option has been removed, since 540nothing needs it anymore. 541 542+-----------------------------------------------------------------------+ 543+ UPGRADING DRAGONFLY FROM 3.0 TO LATER VERSIONS + 544+-----------------------------------------------------------------------+ 545 546APIC_IO OPTION REMOVED 547---------------------- 548 549The APIC_IO kernel option is no longer accepted after having been without 550effect for a while. The hw.ioapic_enable tunable now serves its purpose. 551If you have 'options APIC_IO' in your kernel config, you'll have to 552remove it. 553 554WATCHDOG_ENABLE & HW_WDOG OPTIONS REMOVED 555----------------------------------------- 556 557The wdog framework is now compiled into our kernels by default, so the 558options are no longer needed. 559 560DOSCMD(1) REMOVED 561----------------- 562 563doscmd(1) has been removed. It was i386 only. The doscmd(1) specific 564NO_X make.conf option was removed too. 565 566GCC 4.7 567------- 568 569GCC 4.7 has been brought in and replaces GCC 4.1 as DragonFly's non- 570default compiler in base (default is still GCC 4.4). 571 572Users who wish to build only GCC 4.4 have to replace NO_GCC41 with 573NO_GCC47 in /etc/make.conf. 574 575USB4BSD 576------- 577 578A new USB stack (from FreeBSD) has been brought in. The following 579modules have been ported so far: usb, uhci, ohci, ehci, xhci, umass, 580usfs, uether, if_axe, if_udav, ukbd, ums, uep, uhid, usb_quirk, 581and uaudio. 582 583It is not yet the default. To activate it, WANT_USB4BSD=yes has to 584be put in make.conf and device "usb4bsd" (quotes needed) has to 585replace device usb in the kernel config. After that, a full 586build/install/upgrade cycle is needed. 587 588Note that this is experimental and incomplete, but we are interested 589in hearing about issues with it, of course. 590 591ISA SUPPORT REMOVED FROM AIC-6260/6360 DRIVER 592--------------------------------------------- 593 594ISA adapter support was dropped from the aic(4) driver. 595 596+-----------------------------------------------------------------------+ 597+ UPGRADING DRAGONFLY FROM 2.10 TO LATER VERSIONS + 598+-----------------------------------------------------------------------+ 599 600SEVERAL ISA DRIVERS REMOVED 601--------------------------- 602 603The following ISA only drivers have been removed along with a couple of 604associated userland tools: 605 606aha(4) 607asc(4) & sasc(1) 608ctx 609dgb(4) 610el(4) 611gpib 612gsc(4) & sgsc(1) 613ie(4) 614labpc(4) 615le(4) 616mse(4) 617rc(4) 618rdp(4) 619spigot 620tw(4) & xten(1) & xtend(8) 621wl(4) & wlconfig(8) 622wt(4) 623 624Note that two of these drivers (aha(4) and ie(4)) are in our GENERIC 625config and one (aha(4)) is in our X86_64_GENERIC kernel configuration 626file. 627 628If buildkernel complains about any of these drivers, just remove them 629from your kernel configuration. 630 631BINUTILS 2.20 632------------- 633Binutils 2.20 has been removed in favor of Binutils 2.22. The accepted 634values of BINUTILSVERS are now binutils221 and binutils222 (default). 635 636BUILDWORLD/-KERNEL PARALLELIZATION WORK 637--------------------------------------- 638Due to changes in the way we build with more than one make job, you 639will have to update install(1) and mkdir(1) prior to buildworld if you 640want to build with 'make -j': 641 642cd /usr/src/usr.bin/xinstall; make; make install; make clean 643cd /usr/src/bin/mkdir; make; make install; make clean 644 645DMA(8) UPGRADE 646-------------- 647dma(8) has been upgraded to v0.7 which no longer supports the 648/etc/dma/virtusertable. Some of its functionality has been replaced 649with the MASQUERADE keyword and the EMAIL environment variable (see 650the dma(8) manual page). 651 652+-----------------------------------------------------------------------+ 653+ UPGRADING DRAGONFLY FROM 2.8 TO LATER VERSIONS + 654+-----------------------------------------------------------------------+ 655 656GCC 4.4 & BINUTILS 2.21 657----------------------- 658 659GCC 4.4 has been made DragonFly's default compiler and Binutils 2.21 has 660been made DragonFly's default Binutils. 661 662That means that any settings that set CCVER to 'gcc44' are not needed 663anymore. Instead, CCVER can be set to 'gcc41' to go back to using 664GCC 4.1. 665 666It also means that 'binutils221' as a value for BINUTILSVER has no 667effect anymore. 2.17 has been removed and 'binutils220' is available 668as an option. 669 670The NO_GCC44 option has been removed and will not affect the build 671anymore. There is now a NO_GCC41 option that will prevent GCC 4.1 from 672building in a similar fashion. 673 674Note that you must do a full buildworld/buildkernel for upgrading. 675 676pkg_radd settings 677----------------- 678 679The config file for pkg_radd has moved from /etc/settings.conf to 680/etc/pkg_radd.conf. Save the contents of settings.conf before upgrading 681if this is needed. This warning only applies if /etc/settings.conf 682exists. pkg_radd will continue to work with defaults. 683 684+-----------------------------------------------------------------------+ 685+ 20100927 + 686+ UPGRADING DRAGONFLY FROM 2.6 to 2.8 or HEAD + 687+-----------------------------------------------------------------------+ 688 689OpenSSL 690-------- 691 692OpenSSL has been upgraded, and SHLIB_MAJOR was bumped for libssh and libcrypto. 693This shouldn't break any 3rd-party software, but you'll need to recompile your 6943rd-party software if you want it to link against the new version of OpenSSL. 695 696Loader 697------- 698 699A new loader (dloader) has been added which better handles booting from 700multiple kernel/module versions. 701 702To upgrade (Only for this upgrade, for post 2.8 upgrades see GENERAL below) 703 704 cd /usr/src 705 make buildworld 706 make installworld 707 make upgrade 708 make buildkernel KERNCONF=<KERNELNAME> 709 make installkernel KERNCONF=<KERNELNAME> 710 711Note that you must installworld and run the 'upgrade' target before 712installing the new kernel. 713 714BIND 715----- 716 717BIND has been removed from the base system. The ldns and drill tools have 718been added for basic functionality. Use 'drill' where you would normally 719use nslookup or dig, or install BIND from pkgsrc. It's available as 720net/bind95, net/bind96, or net/bind97 as of this writing. 721 722This only affects older systems upgrading to 2.8. New 2.8+ installs 723include BIND as a pkgsrc package. 724 725+-----------------------------------------------------------------------+ 726+ UPGRADING DRAGONFLY ON AN EXISTING DRAGONFLY SYSTEM + 727+ GENERAL + 728+-----------------------------------------------------------------------+ 729 730Instructions on how to obtain and maintain DragonFly source code using git 731are in the development(7) manual page. 732 733To upgrade a DragonFly system from sources you run the following sequence: 734 735 cd /usr/src 736 make buildworld 737 make buildkernel KERNCONF=<KERNELNAME> 738 make installkernel KERNCONF=<KERNELNAME> 739 make installworld 740 741You will also want to run the 'upgrade' target to upgrade your /etc and the 742rest of your system. The upgrade target is aware of stale files created by 743older DragonFly installations and should delete them automatically. 744 745 make upgrade 746 747See the build(7) manual page for further information. 748 749Once you've done a full build of the world and kernel you can do incremental 750upgrades of either by using the 'quickworld' and 'quickkernel' targets 751instead of 'buildworld' and 'buildkernel'. If you have any problems with 752the quick targets, try updating your repo first, and then a full buildworld 753and buildkernel as shown above, before asking for help. 754 755+-----------------------------------------------------------------------+ 756+ UPGRADING FROM DRAGONFLY <= 2.0 TO DRAGONFLY >= 2.1 + 757+-----------------------------------------------------------------------+ 758 759In 2.1 kernel and modules has moved to boot directory. For most cases 760this is handled automatically by 'make upgrade'. A few cases needs manual 761intervention: 762 763 * When installing a kernel without first doing a make buildworld, 764 installworld and upgrade to the same DESTDIR as kernel: 765 make DESTDIR/boot directory and move kernel and modules into this boot 766 directory; also move kernel.old and modules.old. 767 Typical example is vkernel(7), use (no modules used): 768 769 cd /var/vkernel 770 mkdir boot 771 chflags noschg kernel 772 mv kernel kernel.old boot 773 chflags schg boot/kernel 774 775 * When using a boot-only partition, /boot/loader.rc needs to be edited: 776 delete occurrences of '/boot/'. 777 These occurences can normally be deleted in any case, see loader(8). 778 779+-----------------------------------------------------------------------+ 780+ UPGRADING FROM DRAGONFLY <= 1.8 TO DRAGONFLY >= 1.9 + 781+-----------------------------------------------------------------------+ 782 783In 1.9 major changes to the disk management infrastructure have taken 784place. make upgrade may not catch all of your disk devices in /dev, 785so after upgrading be sure to cd /dev; ./MAKEDEV <blah> where <blah> 786are all of your disk devices. HOWEVER, from late 2.3 on we run devfs 787and MAKEDEV no longer exists. 788 789The biggest changes in 1.9 are: 790 791(1) That whole-slice devices such as da0s1 no longer share the same device 792 id as partition c devices such as da0s1c. 793 794(2) The whole-disk device (e.g. da0) is full raw access to the disk, 795 with no snooping or reserved sectors. Consequently you cannot run 796 disklabel on this device. Instead you must run disklabel on a 797 whole-slice device. 798 799(3) The 'compatibility' partitions now use slice 0 in the device name, 800 so instead of da0a you must specify da0s0a. Also, as per (1) above, 801 accessing the disklabel for the compatibility partitions must be 802 done via slice 0 (da0s0). 803 804(4) Many device drivers that used to fake up labels, such as CD, ACD, VN, 805 and CCD now run through the disk management layer and are assigned 806 real disk management devices. VN and CCD in particular do not usually 807 use a MBR and disklabels must be accessed through the compatibility 808 slice 0. Your /etc/ccd.conf file still specifies 'ccd0', though, you 809 don't name it 'ccd0s0' in the config file. 810 811Generally speaking, you have to get used to running fdisk and disklabel on 812the correctly specified device names. A lot of the wiggle, such as running 813disklabel on a partition, has been removed. 814 815+-----------------------------------------------------------------------+ 816+ UPGRADING FROM OLDER VERSIONS OF DRAGONFLY OR FREEBSD + 817+-----------------------------------------------------------------------+ 818 819> Kerberos IV 820------------- 821 822Kerberos IV (eBones) was removed from the tree, please consider moving to 823Kerberos 5 (Heimdal). 824 825> Package Management System 826--------------------------- 827 828Starting with the 1.4 release, DragonFly uses NetBSD's pkgsrc package 829management system. The necessary tools to build and maintain packages 830are provided in /usr/pkg/bin and /usr/pkg/sbin. Make sure that these 831directories are in your PATH variable. 832 833In order to obtain a reasonably current snapshot of the pkgsrc tree, use 834the tarball from NetBSD: 835 836 fetch -o /tmp/pkgsrc.tar.gz ftp://ftp.NetBSD.org/pub/NetBSD/packages/pkgsrc.tar.gz 837 cd /usr; tar -xzf /tmp/pkgsrc.tar.gz; chown -R root:wheel pkgsrc 838 839This tree can then be kept up to date with cvs update: 840 841 cd /usr/pkgsrc; cvs up 842 843NOTE! If you upgraded from a pre-1.4 system to 1.4 or later, you need to 844build and install the pkgsrc bootstrap manually: 845 846 cd /usr/pkgsrc/bootstrap 847 ./bootstrap --pkgdbdir /var/db/pkg --prefix /usr/pkg 848 849+-----------------------------------------------------------------------+ 850+ UPGRADING DRAGONFLY ON AN EXISTING DRAGONFLY SYSTEM + 851+ UPDATING FROM PRE-1.2 SYSTEMS OR FreeBSD 4.x TO + 852+ DRAGONFLY 1.3+ (EITHER PREVIEW or HEAD) + 853+-----------------------------------------------------------------------+ 854 855The compatibility shims for the build environment have been removed, you 856have to update to DragonFly 1.2 release branch first. 857 858The default PAM configuration has moved from /etc/pam.conf to /etc/pam.d/. 859The existing configuration can be converted using /etc/pam.d/convert.sh. 860Entries in /etc/pam.d/ override entries in /etc/pam.conf. In addition 861the pam_skey.so module was retired, you have to remove it manually from 862your configuration, when you convert it. 863 864> Required user and group IDs when upgrading from either FreeBSD or DragonFly 865--------------------- 866 867The following users may be missing from your password file. Use vipw and 868add any that are missing: 869 870smmsp:*:25:25::0:0:Sendmail Submission User:/var/spool/clientmqueue:/sbin/nologin 871_pflogd:*:64:64::0:0:pflogd privsep user:/var/empty:/sbin/nologin 872 873The following groups may be missing from your group file. Use vi /etc/group 874and add any that are missing: 875 876smmsp:*:25: 877authpf:*:63: 878_pflogd:*:64: 879 880 881> Upgrading to DragonFly from FreeBSD 882--------------------- 883 884You can build the DragonFly world and DragonFly kernels on a FreeBSD-4.x or 885FreeBSD-5.x machine and then install DragonFly over FreeBSD, replacing 886FreeBSD. Note that the DragonFly buildworld target does not try to reuse 887make depend information, it starts from scratch, so no pre-cleaning of the 888object hierarchy is necessary. 889 890 # get the CVS repository (it is placed in /home/dcvs, 500MB). 891 # Please use the -h option and a mirror site to pull the 892 # initial repository, but feel free to use the main repository 893 # machine to pull updates. 894 cvsup /usr/share/examples/cvsup/DragonFly-cvs-supfile 895 # install the source from the CVS hierarchy (remove preexisting 896 # FreeBSD src first) (500MB) 897 cd /usr 898 rm -rf src 899 cvs -R -d /home/dcvs checkout -P src 900 901 # build it (500MB used in /usr/obj) 902 # 903 cd /usr/src 904 make buildworld 905 make buildkernel KERNCONF=<KERNELNAME> 906 907Once you have built DragonFly you have to install it over FreeBSD. Since 908DragonFly does not track changes made by FreeBSD to its include file 909hierarchy and include file pollution can cause all sorts of unexpected 910compilation issues to come up, it is best to wipe your include hierarchy 911prior to installing DragonFly. Note that you should not wipe any installed 912FreeBSD header files or binaries until after you have successfully completed 913the build steps above. 914 915 rm -rf /usr/include 916 mkdir /usr/include 917 make installkernel KERNCONF=<KERNELNAME> 918 make installworld 919 920Then you need to upgrade your system. DragonFly's 'make upgrade' target 921will unconditionally upgrade the /etc files that sysops do not usually 922mess around with, such as the files in /etc/rc.d. It will also remove any 923obsolete files such as utilities and manpages that have been removed from 924the system since the version you're coming from. If you are unsure we 925recommend that you make a backup of at least your /etc before applying 926this step. Note that DragonFly's RC system is basically RCNG from 927FreeBSD-5, but there are some differences in the contents of the RC files. 928 929 make upgrade 930 931NOTE! Never do a 'make upgrade' before 'make installworld' has been run. 932Doing so might leave your system in an unusable state. 933 934Finally we recommend that you do an 'ls -lta BLAH' for /bin, /sbin, /usr/bin, 935/usr/bin, and /usr/lib, and remove any stale files that you find. Please 936report these files to the DragonFly developers so that they can be added to 937the 'upgrade' target. 938 939
