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 5.0 TO LATER VERSIONS + 13+-----------------------------------------------------------------------+ 14 15VIRTIO_PCI REMOVED FROM KERNEL CONFIG 16------------------------------------- 17 18The "device virtio_pci" line in X86_64_GENERIC has been removed. People 19with configuration files derived from it have to remove it manually. 20 21VARIOUS 'R' COMMANDS AND DAEMONS REMOVED 22---------------------------------------- 23 24rcp(1), rlogin(1), rlogind(8), rsh(1) and rshd(8) have been removed. 25For those that still need them, there is the net/bsdrcmds port. 26 27VARIOUS FORMER OPTIONS REMOVED 28------------------------------ 29 30Various former kernel configuration options which had been no-ops for 31some time were completely removed: SYSVMSG, SYSVSEM, SYSVSHM, P1003_1B, 32_KPOSIX_VERSION and DSCHED_FQ. Users that have any of these still in 33their kernel configuration files have to remove them. 34 35BOOTSTRAPPING LIMITED FROM PRE 4.4 36---------------------------------- 37 38Upgrading to 5.1 and later versions now require at least 4.4 in 39preparations for upcoming base compilers updates. 40 41IF_PPP, PPPD, IF_FAITH, AND FAITHD REMOVED 42------------------------------------------ 43 44if_ppp has been replaced by "user ppp", i.e. ppp(8) and tun(4). It had 45already been removed from our default kernel configuration before 5.0, 46so only people with custom configurations based on earlier X86_64_GENERIC 47will have to remove it manually. 48 49The faith(4) interface has been completely removed after it had also 50been removed from our default kernel configuration. 51 52+-----------------------------------------------------------------------+ 53+ UPGRADING DRAGONFLY FROM 4.8 TO LATER VERSIONS + 54+-----------------------------------------------------------------------+ 55 56FFS_ROOT OPTION DISABLED 57------------------------ 58 59The FFS_ROOT option has been made a no-op and will be completely removed 60at some point in the future. Users with a custom kernel configuration 61can remove this option from it now. 62 63+-----------------------------------------------------------------------+ 64+ UPGRADING DRAGONFLY FROM 4.6 TO LATER VERSIONS + 65+-----------------------------------------------------------------------+ 66 67AHC, AHD, AIC, NCV, NSP AND STG DRIVERS REMOVED 68----------------------------------------------- 69 70They were all in our X86_64_GENERIC kernel configuration file, along with 71the AHC_REG_PRETTY_PRINT and AHD_REG_PRETTY_PRINT options, so any custom 72configuration files derived from it need adjustment. 73 74PORTAL FILE SYSTEM REMOVED 75-------------------------- 76 77It has been broken for a long time now. 78 79BINUTILS 2.27 REPLACES 2.24, PRIMARY 80------------------------------------ 81 82The oldest of the two versions of Binutils, version 2.24, was removed 83and replaced with Binutils 2.27. It becomes the primary version version 84of binutils and version 2.25 becomes the alternate. 85 86The accepted values of BINUTILSVER are now "binutils227" (default) and 87"binutils225". The building of Binutils 2.25 can be prevented by setting 88NO_ALTBINUTILS=yes in make.conf. 89 90COMPAT_43 KERNEL OPTION REMOVED 91------------------------------- 92 93It was commented out in our default configs for several years now, but 94might still be present in custom configs created before Nov. 2011. 95 96OPENSSL REMOVED 97--------------- 98 99OpenSSL has been removed from base and replaced with a private version of 100LibreSSL. The previously installed OpenSSL libraries, headers, and man 101pages will remain on the system unless the "make upgrade" command is 102specifically instructed to remove them. To do this, define 103REMOVE_OPENSSL_FILES for the upgrade command, e.g. 104"make upgrade REMOVE_OPENSSL_FILES=yes" 105 10628-Oct-2016: openssl has been replaced by ressl. It is recommended that any 107stale OpenSSL files be removed to avoid configuration scripts from using 108the stale and potentially vulnerable version, but all binaries that are 109dynamically linked to the OpenSSL libraries should be rebuilt first to 110avoid breakage. 111 112OPENSSH HPN REMOVED 113------------------- 114 115It has become too cumbersome to maintain HPN patches in OpenSSH in base. 116To use OpenSSH in base remove HPN config, if you have added it. 117Check files below for HPN config, see a few lines below. 118 /etc/ssh/ssh_config, /etc/ssh/sshd_config, ~/.ssh/config 119sshd(8) will fail to start if HPN config is used. 120 121NOTE: HPN config in sshd_config will prohibit remote access to host using ssh. 122 123HPN config: 124HPNDisabled 125HPNBufferSize 126TcpRcvBuf 127TcpRcvBufPoll 128NoneEnabled 129NoneSwitch 130cipher MTR-AES-CTR 131cipher NONE 132 133OpenSSH HPN is a patch set to OpenSSH providing higher performance under some 134circumstances, especially for networking. 135If HPN functionality is needed, install security/openssh from dports. 136 137CS, EX AND VX DRIVERS REMOVED 138----------------------------- 139 140The cs(4), ex(4) and vx(4) drivers have been removed. They were very 141old and its doubtful they ever worked properly in x86_64 but they were 142in X86_64_GENERIC, so custom configurations derived from it have to be 143adjusted. 144 145+-----------------------------------------------------------------------+ 146+ UPGRADING DRAGONFLY FROM 4.4 TO LATER VERSIONS + 147+-----------------------------------------------------------------------+ 148 149AMD REMOVED 150----------- 151 152The am-utils automounter suite has been removed. It stopped working 153at some point and was never fixed. autofs(5) and the associated 154userland has been brought in from FreeBSD and replaces it. 155 156AN DRIVER REMOVED 157----------------- 158 159The an(4) driver has been removed. It was in the X86_64_GENERIC kernel 160config file, so any configurations derived from it have to be adjusted. 161 162/DEV/DRI GROUP CHANGED 163---------------------- 164 165The default group assigned to /dev/dri entries has been changed 166from 'wheel' to 'video' with the id of '44'. If you want to have 167access to the dri devices please add yourself to the video group 168with: 169 170# pw groupmod video -m $USER 171 172+-----------------------------------------------------------------------+ 173+ UPGRADING DRAGONFLY FROM 4.2 TO LATER VERSIONS + 174+-----------------------------------------------------------------------+ 175 176DSCHED REMOVED 177-------------- 178 179dsched(4) has been removed and one of its kernel options, DSCHED_FQ, was 180in our default kernel config file. So the DSCHED_FQ option has been turned 181into a no-op for now and can be removed from custom configurations. 182 183EST DRIVER REMOVED, COMPILE_ET AND LIBCOM_ERR TOO 184------------------------------------------------- 185 186The est(4) driver has been removed. All CPUs it supported (except one) 187were 32 bits only. Those who are still using the Core 2 Duo T7500 should 188report back if there are any issues with this CPU and our regular ACPI 189P-state support. 190 191Also, compile_et(1) and com_err(3) have been removed as well. They 192should have been removed along with kerberos support, back in 2009. 193 194SEVERAL LOCALES RENAMED 195----------------------- 196 197Several locales were using obsolete and misleading names, and thus have 198been adjusted to current standards. Any users of the following locales 199need to select alternates: 200 201DFLY 4.2 locale DFLY 4.4 alterative locale 202--------------- ------------------------------------ 203mn_MN.UTF-8 mn_Cyrl_MN.UTF-8 204no_NO.UTF-8 nb_NO.UTF-8 or nn_NO.UTF-8 205no_NO.ISO8859-1 nb_NO.ISO8869-1 or nn_NO.ISO8859-1 206no_NO.ISO8859-15 nb_NO.ISO8859-15 or nn_NO.ISO8859-15 207sr_YU.UTF-8 sr_Cyrl_RS.UTF-8 or sr_Latn_RS.UTF-8 208sr_YU.ISO8859-5 sr_Cyrl_RS.ISO8859-5 209sr_YU.ISO8859-2 sr_Latn_RS.ISO8859-2 210zh_CN.GBK zh_Hans_CN.GBK 211zh_CN.UTF-8 zh_Hans_CN.UTF-8 212zh_CN.eucCN zh_Hans_CN.eucCN 213zh_CN.GB2312 zh_Hans_CH.GB2312 214zh_CN.GB18030 zh_Hans_CH.GB18030 215zh_HK.Big5HKSCS zh_Hant_HK.Big5HKSCS 216zh_HK.UTF_8 zh_Hant_HK.UTF-8 217zh_TW.Big5 zh_Hant_TW.Big5 218zh_TW.UTF-8 zh_Hant_TW.UTF-8 219 220+-----------------------------------------------------------------------+ 221+ UPGRADING DRAGONFLY FROM 4.0 TO LATER VERSIONS + 222+-----------------------------------------------------------------------+ 223 224BINUTILS 2.25 REPLACES 2.22, PRIMARY 225------------------------------------ 226 227The oldest of the two versions of Binutils, version 2.22, was removed 228and replaced with Binutils 2.25. It becomes the primary version version 229of binutils and version 2.24 becomes the alternate. There are 8 current 230CVE written against 2.24, so for security reasons version 2.25 should 231always be used. 232 233The accepted values of BINUTILSVER are now "binutils225" (default) and 234"binutils224". The building of Binutils 2.24 can be prevented by setting 235NO_ALTBINUTILS=yes in make.conf. 236 237LOADER OPTIONS CHANGED 238---------------------- 239 240Right after the development branch started, the Fred art accompanying the 241loader menu was improved. The line between Fred and the menu was removed 242by default (but can optionally be returned) and the placement shifted as 243a result. The drawing was improved, and the colored version was improved, 244changing the eyes and wing color from white to red. A new color version 245of Fred was added, one with a blue scheme. 246 247The loader menu defaults have changed since release 4.0: The vertical 248line was removed, the loader is displayed in color by default*, and the 249blue scheme is used. 250 251The loader.conf changes are: 252loader_color: option has been removed 253loader_plain: option has been added, it changed menu to monochrome 254fred_is_red: changes color scheme from blue to red 255fred_is_blue: option existed only on 4.1, it has been removed 256fred_separated: Adds line between Fred and menu (as seen previously) 257 258* If loader.conf defines "console" as "comconsole" or "console" is defined 259 in the environment as "comconsole" then color will not be displayed, 260 even if loader_plain value is "NO". 261 262SENDMAIL REMOVED FROM BASE 263-------------------------- 264 265The only Mail Transfer Agent provided now is DragonFly Mail Agent (dma). 266If the system being upgraded is still configured to use the sendmail 267binaries from base, the "make upgrade" command will fail. 268 269The administrator must change /etc/mail/mailer.conf to switch the 270mailwrapper to dma or a DPorts-based MTA prior to running the upgrade 271command that permanently removes sendmail executables and could 272potentially break a running mail server. 273 274Refer: http://www.dragonflybsd.com/docs/docs/newhandbook/mta/ for 275detailed instructions on how to configure the MTA selection. 276 277_KPOSIX_VERSION and P1003_1B OPTIONS REMOVED 278-------------------------------------------- 279 280The _KPOSIX_VERSION and P1003_1B kernel options have been changed to 281no-ops. They can be removed from custom kernel configurations. 282 283SOUND SYSTEM UPDATED FROM FreeBSD 11-CURRENT 284-------------------------------------------- 285 286Many more sound devices may be detected. 287 288If the default device choosen isn't to your liking, setting the sysctl 289hw.snd.default_unit to a different number will change it. 290 291SCTP SUPPORT DROPPED 292-------------------- 293 294Support for the SCTP protocol has been removed. 295 296OLD USB DRIVERS REMOVED 297----------------------- 298 299The old USB stack, along with the kernel config option "device oldusb" 300and the make.conf variable "WANT_OLDUSB" have been removed. This means 301that for custom kernel configuration files which were derived from a 302GENERIC or X86_64_GENERIC file prior to making the usb4bsd stack default, 303various (old USB stack specific) devices will now complain about being 304unknown: 305 306 * oldusb (obviously) 307 * natausb (not yet ported to usb4bsd) 308 * rue (not yet ported to usb4bsd) 309 * ugen (no longer needed in usb4bsd) 310 * urio (not yet ported to usb4bsd) 311 * uscanner (no longer needed in usb4bsd) 312 313They should be removed or commented out in such custom kernel configs. 314 315GCC 5 316----- 317 318The GCC 4.4 compiler has been retired. It has been replaced by a GCC 5.1. 319The following make.conf variables no longer work: NO_GCC44, NO_OBJC, and 320NO_CXX. The latter was never documented and the latest versions of GCC are 321partially written in C++ so a C++ compiler is no longer optional. In 322practical terms it has not been optional for many years as other base 323components are also written in C++. The resource savings by avoiding 324building Objective-C compiler is so small, the complexity added by NO_OBJC 325internally was deemed a bad tradeoff so that is the reason for its removal. 326Also note that no "info" pages are installed with GCC 5. After this entry 327was originally written, all info pages were removed from DragonFly. 328 329GCC 5.1 has been designated as the primary compiler. As such, there is a 330new make.conf variable, NO_ALTCOMPILER. It will block the rebuilding of 331the designated secondary compiler, GCC 4.7. However, while DPorts 332primarily uses GCC 5 to build ports now, it still uses GCC 4.7 as well, so 333if building ports from source is desired, don't block building of the 334secondary compiler. 335 336+-----------------------------------------------------------------------+ 337+ UPGRADING DRAGONFLY FROM 3.8 TO LATER VERSIONS + 338+-----------------------------------------------------------------------+ 339 340SMP AND DEVICE_POLLING OPTIONS MADE UNKNOWN 341------------------------------------------- 342 343DEVICE_POLLING was replaced by IFPOLL_ENABLE and the former SMP code is 344the default now (even on single-core systems), both for, like, 21 months. 345We kept the options around as no-ops as a convenience, to allow people 346using the same config for the then current release and the then current 347master. That period is now over, so any configs still having those 348options have to be adjusted. 349 350SYSVIPC SYSCALLS MADE NON-OPTIONAL 351---------------------------------- 352 353The code related to the SYSVMSG, SYSVSEM and SYSVSHM kernel options is 354now compiled in by default. The options are no-ops for now. 355 356DEFAULT DRIVER CHANGED FOR LSI "THUNDERBOLT" SERIES RAID CONTROLLERS 357-------------------------------------------------------------------- 358 359The default driver for those controllers is now mrsas(4) due to reports 360of file system corruption using the mfi(4) driver. The whole issue (and 361how to deal with potential problems when switching) was explained here: 362 363http://lists.dragonflybsd.org/pipermail/users/2014-July/128703.html 364 365A tunable is provided for letting those controllers still attach via 366the mfi(4) driver, hw.mrsas.mfi_enable (see mrsas(4) manual page). 367 368OLDER NETWORK DRIVERS MOVED TO I386 ONLY 369---------------------------------------- 370 371The following drivers have been made i386 only: ed(4), sr(4), ng_sync_ar 372and ng_sync_sr. ed(4) used to be in X86_64_GENERIC, so it has to be 373removed in kernel configs derived from X86_64_GENERIC. 374 375+-----------------------------------------------------------------------+ 376+ UPGRADING DRAGONFLY FROM 3.6 TO LATER VERSIONS + 377+-----------------------------------------------------------------------+ 378 379UPDATE FROM MOST RECENT 3.6 380--------------------------- 381 382Versions of 3.6 built before June 25th have a bug where installworld might 383crash during installation of the new initrd. Upgrade to the latest version 384of 3.6 before updating to 3.8 or later. 385 386ATM, IPX, NCP AND NWFS SUPPORT DROPPED 387-------------------------------------- 388 389Support for the IPX and NCP network protocols and for mouting NetWare 390file systems has been dropped. Dito for ATM protocol support. 391 392INITRD IMAGES NOW INSTALLED BY DEFAULT 393-------------------------------------- 394 395An initial ramdisk image is now installed in /boot/kernel/initrd.img.gz 396 397Older images installed under the file name of initrd.img will be removed 398automatically by the make upgrade process. 399 400USB4BSD IS NOW THE DEFAULT USB STACK 401------------------------------------ 402 403To get back to the old stack, put "WANT_OLDUSB=yes" in /etc/make.conf and 404replace "device usb" with "device oldusb" in the kernel configuration. 405 406MORE ISA SUPPORT DROPPED 407------------------------ 408 409ISA support has been dropped from the following drivers: adv(4), an(4), 410ar(4), cs(4), digi(4), ed(4), ep(4), ex(4), fe(4), lnc(4), sbni(4), 411si(4), sn(4), and stg(4). 412 413+-----------------------------------------------------------------------+ 414+ UPGRADING DRAGONFLY FROM 3.4 TO LATER VERSIONS + 415+-----------------------------------------------------------------------+ 416 417ABI CHANGE 418---------- 419 420Installed third-party software (dports) will have to be rebuilt after upgrade, 421or reinstalled from binary packages. 422 423UPDATING FROM 3.4 TO 3.6 424------------------------ 425 426This only applies for this specific upgrade due to locale changes; it is 427not needed for upgrades after 3.6. Please update in this order: 428 429make buildworld 430make buildkernel 431make installworld 432make installkernel 433*reboot* 434make upgrade 435 436See this mailing list post for details: 437http://lists.dragonflybsd.org/pipermail/users/2013-September/090163.html 438 439CYRIX OPTIONS REMOVED 440--------------------- 441 442The following Cyrix related options have been removed: CPU_BTB_EN, 443CPU_CYRIX_NO_LOCK, CPU_DIRECT_MAPPED_CACHE, CPU_DISABLE_5X86_LSSER, 444CPU_FASTER_5X86_FPU, CPU_IORT, CPU_LOOP_EN, CPU_RSTK_EN, CPU_SUSP_HLT, 445CYRIX_CACHE_WORKS, and CYRIX_CACHE_REALLY_WORKS 446 447ISA SUPPORT REMOVED FROM RP(4) 448------------------------------ 449 450ISA support has been removed from the rp(4) driver. It is now PCI only. 451 452+-----------------------------------------------------------------------+ 453+ UPGRADING DRAGONFLY FROM 3.2 TO LATER VERSIONS + 454+-----------------------------------------------------------------------+ 455 456COMPAT_SUNOS OPTION REMOVED 457--------------------------- 458 459The COMPAT_SUNOS option has been removed. It was meant to provide binary 460compatibility with SunOS 4.x for the sparc32 port of 4.4BSD. 461 462ISA SOUND CARD SUPPORT REMOVED 463------------------------------ 464 465The following modules have been removed (all for ISA sound cards): 466snd_ad1816.ko, snd_ess.ko, snd_mss.ko, snd_sb8.ko, snd_sb16.ko, snd_sbc.ko 467 468GCC 4.7 469------- 470 471DragonFly has switched base compilers. GCC 4.7 is now the default 472compiler and GCC 4.4 is the alternative compiler. The "NO_GCC47" make 473variable ceases to work now. 474 475Users who wish to build only GCC 4.7 have to use NO_GCC44 in the 476/etc/make.conf to prohibit GCC 4.4 from building. However, using it is 477highly discouraged. There are a few packages in pkgsrc that do not build 478with GCC 4.7 and the new "DPorts" system uses GCC 4.4 by default. At 479this time, it is recommended to keep both compilers on the base system. 480 481SMP OPTION REMOVED 482------------------ 483 484The SMP kernel option has been made a no-op. All kernels now feature SMP 485support. If you have 'options SMP' in your kernel config, you can as well 486remove it. 487 488DEVICE_POLLING OPTION REPLACED BY IFPOLL_ENABLE OPTION, KTR_POLLING REMOVED 489--------------------------------------------------------------------------- 490 491The DEVICE_POLLING kernel option has been made a no-op and it has been 492replaced by IFPOLL_ENABLE. If you have 'options DEVICE_POLLING' in your 493kernel config, you need to change it to IFPOLL_ENABLE. 494 495Also, the KTR_POLLING kernel option has been removed, so it must be 496removed from kernel configs that have it. 497 498BUSLOGIC, CYCLADES AND STALLION ISA SUPPORT REMOVED 499--------------------------------------------------- 500 501The bt(4) driver for Buslogic SCSI adapters has been made PCI only. ISA 502cards will no longer be detected. 503 504The same has been done for Stallion multiport serial controllers. stli(4) 505has been completely removed (along with the stlload(8) and stlstty(8) 506utilities) and stl(4) was changed to support only PCI cards. Similarly, 507ISA support was removed from cy(4) too. All these drivers are i386 only. 508 509COMPAT_OLDISA OPTION GONE 510------------------------- 511 512The i386 specific COMPAT_OLDISA kernel option has been removed, since 513nothing needs it anymore. 514 515+-----------------------------------------------------------------------+ 516+ UPGRADING DRAGONFLY FROM 3.0 TO LATER VERSIONS + 517+-----------------------------------------------------------------------+ 518 519APIC_IO OPTION REMOVED 520---------------------- 521 522The APIC_IO kernel option is no longer accepted after having been without 523effect for a while. The hw.ioapic_enable tunable now serves its purpose. 524If you have 'options APIC_IO' in your kernel config, you'll have to 525remove it. 526 527WATCHDOG_ENABLE & HW_WDOG OPTIONS REMOVED 528----------------------------------------- 529 530The wdog framework is now compiled into our kernels by default, so the 531options are no longer needed. 532 533DOSCMD(1) REMOVED 534----------------- 535 536doscmd(1) has been removed. It was i386 only. The doscmd(1) specific 537NO_X make.conf option was removed too. 538 539GCC 4.7 540------- 541 542GCC 4.7 has been brought in and replaces GCC 4.1 as DragonFly's non- 543default compiler in base (default is still GCC 4.4). 544 545Users who wish to build only GCC 4.4 have to replace NO_GCC41 with 546NO_GCC47 in /etc/make.conf. 547 548USB4BSD 549------- 550 551A new USB stack (from FreeBSD) has been brought in. The following 552modules have been ported so far: usb, uhci, ohci, ehci, xhci, umass, 553usfs, uether, if_axe, if_udav, ukbd, ums, uep, uhid, usb_quirk, 554and uaudio. 555 556It is not yet the default. To activate it, WANT_USB4BSD=yes has to 557be put in make.conf and device "usb4bsd" (quotes needed) has to 558replace device usb in the kernel config. After that, a full 559build/install/upgrade cycle is needed. 560 561Note that this is experimental and incomplete, but we are interested 562in hearing about issues with it, of course. 563 564ISA SUPPORT REMOVED FROM AIC-6260/6360 DRIVER 565--------------------------------------------- 566 567ISA adapter support was dropped from the aic(4) driver. 568 569+-----------------------------------------------------------------------+ 570+ UPGRADING DRAGONFLY FROM 2.10 TO LATER VERSIONS + 571+-----------------------------------------------------------------------+ 572 573SEVERAL ISA DRIVERS REMOVED 574--------------------------- 575 576The following ISA only drivers have been removed along with a couple of 577associated userland tools: 578 579aha(4) 580asc(4) & sasc(1) 581ctx 582dgb(4) 583el(4) 584gpib 585gsc(4) & sgsc(1) 586ie(4) 587labpc(4) 588le(4) 589mse(4) 590rc(4) 591rdp(4) 592spigot 593tw(4) & xten(1) & xtend(8) 594wl(4) & wlconfig(8) 595wt(4) 596 597Note that two of these drivers (aha(4) and ie(4)) are in our GENERIC 598config and one (aha(4)) is in our X86_64_GENERIC kernel configuration 599file. 600 601If buildkernel complains about any of these drivers, just remove them 602from your kernel configuration. 603 604BINUTILS 2.20 605------------- 606Binutils 2.20 has been removed in favor of Binutils 2.22. The accepted 607values of BINUTILSVERS are now binutils221 and binutils222 (default). 608 609BUILDWORLD/-KERNEL PARALLELIZATION WORK 610--------------------------------------- 611Due to changes in the way we build with more than one make job, you 612will have to update install(1) and mkdir(1) prior to buildworld if you 613want to build with 'make -j': 614 615cd /usr/src/usr.bin/xinstall; make; make install; make clean 616cd /usr/src/bin/mkdir; make; make install; make clean 617 618DMA(8) UPGRADE 619-------------- 620dma(8) has been upgraded to v0.7 which no longer supports the 621/etc/dma/virtusertable. Some of its functionality has been replaced 622with the MASQUERADE keyword and the EMAIL environment variable (see 623the dma(8) manual page). 624 625+-----------------------------------------------------------------------+ 626+ UPGRADING DRAGONFLY FROM 2.8 TO LATER VERSIONS + 627+-----------------------------------------------------------------------+ 628 629GCC 4.4 & BINUTILS 2.21 630----------------------- 631 632GCC 4.4 has been made DragonFly's default compiler and Binutils 2.21 has 633been made DragonFly's default Binutils. 634 635That means that any settings that set CCVER to 'gcc44' are not needed 636anymore. Instead, CCVER can be set to 'gcc41' to go back to using 637GCC 4.1. 638 639It also means that 'binutils221' as a value for BINUTILSVER has no 640effect anymore. 2.17 has been removed and 'binutils220' is available 641as an option. 642 643The NO_GCC44 option has been removed and will not affect the build 644anymore. There is now a NO_GCC41 option that will prevent GCC 4.1 from 645building in a similar fashion. 646 647Note that you must do a full buildworld/buildkernel for upgrading. 648 649pkg_radd settings 650----------------- 651 652The config file for pkg_radd has moved from /etc/settings.conf to 653/etc/pkg_radd.conf. Save the contents of settings.conf before upgrading 654if this is needed. This warning only applies if /etc/settings.conf 655exists. pkg_radd will continue to work with defaults. 656 657+-----------------------------------------------------------------------+ 658+ 20100927 + 659+ UPGRADING DRAGONFLY FROM 2.6 to 2.8 or HEAD + 660+-----------------------------------------------------------------------+ 661 662OpenSSL 663-------- 664 665OpenSSL has been upgraded, and SHLIB_MAJOR was bumped for libssh and libcrypto. 666This shouldn't break any 3rd-party software, but you'll need to recompile your 6673rd-party software if you want it to link against the new version of OpenSSL. 668 669Loader 670------- 671 672A new loader (dloader) has been added which better handles booting from 673multiple kernel/module versions. 674 675To upgrade (Only for this upgrade, for post 2.8 upgrades see GENERAL below) 676 677 cd /usr/src 678 make buildworld 679 make installworld 680 make upgrade 681 make buildkernel KERNCONF=<KERNELNAME> 682 make installkernel KERNCONF=<KERNELNAME> 683 684Note that you must installworld and run the 'upgrade' target before 685installing the new kernel. 686 687BIND 688----- 689 690BIND has been removed from the base system. The ldns and drill tools have 691been added for basic functionality. Use 'drill' where you would normally 692use nslookup or dig, or install BIND from pkgsrc. It's available as 693net/bind95, net/bind96, or net/bind97 as of this writing. 694 695This only affects older systems upgrading to 2.8. New 2.8+ installs 696include BIND as a pkgsrc package. 697 698+-----------------------------------------------------------------------+ 699+ UPGRADING DRAGONFLY ON AN EXISTING DRAGONFLY SYSTEM + 700+ GENERAL + 701+-----------------------------------------------------------------------+ 702 703Instructions on how to obtain and maintain DragonFly source code using git 704are in the development(7) manual page. 705 706To upgrade a DragonFly system from sources you run the following sequence: 707 708 cd /usr/src 709 make buildworld 710 make buildkernel KERNCONF=<KERNELNAME> 711 make installkernel KERNCONF=<KERNELNAME> 712 make installworld 713 714You will also want to run the 'upgrade' target to upgrade your /etc and the 715rest of your system. The upgrade target is aware of stale files created by 716older DragonFly installations and should delete them automatically. 717 718 make upgrade 719 720See the build(7) manual page for further information. 721 722Once you've done a full build of the world and kernel you can do incremental 723upgrades of either by using the 'quickworld' and 'quickkernel' targets 724instead of 'buildworld' and 'buildkernel'. If you have any problems with 725the quick targets, try updating your repo first, and then a full buildworld 726and buildkernel as shown above, before asking for help. 727 728+-----------------------------------------------------------------------+ 729+ UPGRADING FROM DRAGONFLY <= 2.0 TO DRAGONFLY >= 2.1 + 730+-----------------------------------------------------------------------+ 731 732In 2.1 kernel and modules has moved to boot directory. For most cases 733this is handled automatically by 'make upgrade'. A few cases needs manual 734intervention: 735 736 * When installing a kernel without first doing a make buildworld, 737 installworld and upgrade to the same DESTDIR as kernel: 738 make DESTDIR/boot directory and move kernel and modules into this boot 739 directory; also move kernel.old and modules.old. 740 Typical example is vkernel(7), use (no modules used): 741 742 cd /var/vkernel 743 mkdir boot 744 chflags noschg kernel 745 mv kernel kernel.old boot 746 chflags schg boot/kernel 747 748 * When using a boot-only partition, /boot/loader.rc needs to be edited: 749 delete occurrences of '/boot/'. 750 These occurences can normally be deleted in any case, see loader(8). 751 752+-----------------------------------------------------------------------+ 753+ UPGRADING FROM DRAGONFLY <= 1.8 TO DRAGONFLY >= 1.9 + 754+-----------------------------------------------------------------------+ 755 756In 1.9 major changes to the disk management infrastructure have taken 757place. make upgrade may not catch all of your disk devices in /dev, 758so after upgrading be sure to cd /dev; ./MAKEDEV <blah> where <blah> 759are all of your disk devices. HOWEVER, from late 2.3 on we run devfs 760and MAKEDEV no longer exists. 761 762The biggest changes in 1.9 are: 763 764(1) That whole-slice devices such as da0s1 no longer share the same device 765 id as partition c devices such as da0s1c. 766 767(2) The whole-disk device (e.g. da0) is full raw access to the disk, 768 with no snooping or reserved sectors. Consequently you cannot run 769 disklabel on this device. Instead you must run disklabel on a 770 whole-slice device. 771 772(3) The 'compatibility' partitions now use slice 0 in the device name, 773 so instead of da0a you must specify da0s0a. Also, as per (1) above, 774 accessing the disklabel for the compatibility partitions must be 775 done via slice 0 (da0s0). 776 777(4) Many device drivers that used to fake up labels, such as CD, ACD, VN, 778 and CCD now run through the disk management layer and are assigned 779 real disk management devices. VN and CCD in particular do not usually 780 use a MBR and disklabels must be accessed through the compatibility 781 slice 0. Your /etc/ccd.conf file still specifies 'ccd0', though, you 782 don't name it 'ccd0s0' in the config file. 783 784Generally speaking, you have to get used to running fdisk and disklabel on 785the correctly specified device names. A lot of the wiggle, such as running 786disklabel on a partition, has been removed. 787 788+-----------------------------------------------------------------------+ 789+ UPGRADING FROM OLDER VERSIONS OF DRAGONFLY OR FREEBSD + 790+-----------------------------------------------------------------------+ 791 792> Kerberos IV 793------------- 794 795Kerberos IV (eBones) was removed from the tree, please consider moving to 796Kerberos 5 (Heimdal). 797 798> Package Management System 799--------------------------- 800 801Starting with the 1.4 release, DragonFly uses NetBSD's pkgsrc package 802management system. The necessary tools to build and maintain packages 803are provided in /usr/pkg/bin and /usr/pkg/sbin. Make sure that these 804directories are in your PATH variable. 805 806In order to obtain a reasonably current snapshot of the pkgsrc tree, use 807the tarball from NetBSD: 808 809 fetch -o /tmp/pkgsrc.tar.gz ftp://ftp.NetBSD.org/pub/NetBSD/packages/pkgsrc.tar.gz 810 cd /usr; tar -xzf /tmp/pkgsrc.tar.gz; chown -R root:wheel pkgsrc 811 812This tree can then be kept up to date with cvs update: 813 814 cd /usr/pkgsrc; cvs up 815 816NOTE! If you upgraded from a pre-1.4 system to 1.4 or later, you need to 817build and install the pkgsrc bootstrap manually: 818 819 cd /usr/pkgsrc/bootstrap 820 ./bootstrap --pkgdbdir /var/db/pkg --prefix /usr/pkg 821 822+-----------------------------------------------------------------------+ 823+ UPGRADING DRAGONFLY ON AN EXISTING DRAGONFLY SYSTEM + 824+ UPDATING FROM PRE-1.2 SYSTEMS OR FreeBSD 4.x TO + 825+ DRAGONFLY 1.3+ (EITHER PREVIEW or HEAD) + 826+-----------------------------------------------------------------------+ 827 828The compatibility shims for the build environment have been removed, you 829have to update to DragonFly 1.2 release branch first. 830 831The default PAM configuration has moved from /etc/pam.conf to /etc/pam.d/. 832The existing configuration can be converted using /etc/pam.d/convert.sh. 833Entries in /etc/pam.d/ override entries in /etc/pam.conf. In addition 834the pam_skey.so module was retired, you have to remove it manually from 835your configuration, when you convert it. 836 837> Required user and group IDs when upgrading from either FreeBSD or DragonFly 838--------------------- 839 840The following users may be missing from your password file. Use vipw and 841add any that are missing: 842 843smmsp:*:25:25::0:0:Sendmail Submission User:/var/spool/clientmqueue:/sbin/nologin 844_pflogd:*:64:64::0:0:pflogd privsep user:/var/empty:/sbin/nologin 845 846The following groups may be missing from your group file. Use vi /etc/group 847and add any that are missing: 848 849smmsp:*:25: 850authpf:*:63: 851_pflogd:*:64: 852 853 854> Upgrading to DragonFly from FreeBSD 855--------------------- 856 857You can build the DragonFly world and DragonFly kernels on a FreeBSD-4.x or 858FreeBSD-5.x machine and then install DragonFly over FreeBSD, replacing 859FreeBSD. Note that the DragonFly buildworld target does not try to reuse 860make depend information, it starts from scratch, so no pre-cleaning of the 861object hierarchy is necessary. 862 863 # get the CVS repository (it is placed in /home/dcvs, 500MB). 864 # Please use the -h option and a mirror site to pull the 865 # initial repository, but feel free to use the main repository 866 # machine to pull updates. 867 cvsup /usr/share/examples/cvsup/DragonFly-cvs-supfile 868 # install the source from the CVS hierarchy (remove preexisting 869 # FreeBSD src first) (500MB) 870 cd /usr 871 rm -rf src 872 cvs -R -d /home/dcvs checkout -P src 873 874 # build it (500MB used in /usr/obj) 875 # 876 cd /usr/src 877 make buildworld 878 make buildkernel KERNCONF=<KERNELNAME> 879 880Once you have built DragonFly you have to install it over FreeBSD. Since 881DragonFly does not track changes made by FreeBSD to its include file 882hierarchy and include file pollution can cause all sorts of unexpected 883compilation issues to come up, it is best to wipe your include hierarchy 884prior to installing DragonFly. Note that you should not wipe any installed 885FreeBSD header files or binaries until after you have successfully completed 886the build steps above. 887 888 rm -rf /usr/include 889 mkdir /usr/include 890 make installkernel KERNCONF=<KERNELNAME> 891 make installworld 892 893Then you need to upgrade your system. DragonFly's 'make upgrade' target 894will unconditionally upgrade the /etc files that sysops do not usually 895mess around with, such as the files in /etc/rc.d. It will also remove any 896obsolete files such as utilities and manpages that have been removed from 897the system since the version you're coming from. If you are unsure we 898recommend that you make a backup of at least your /etc before applying 899this step. Note that DragonFly's RC system is basically RCNG from 900FreeBSD-5, but there are some differences in the contents of the RC files. 901 902 make upgrade 903 904NOTE! Never do a 'make upgrade' before 'make installworld' has been run. 905Doing so might leave your system in an unusable state. 906 907Finally we recommend that you do an 'ls -lta BLAH' for /bin, /sbin, /usr/bin, 908/usr/bin, and /usr/lib, and remove any stale files that you find. Please 909report these files to the DragonFly developers so that they can be added to 910the 'upgrade' target. 911 912
