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 15LIBRADIUS AND LIBTACPLUS REMOVED 16-------------------------------- 17 18Both libraries have been moved from base to DPorts net/ category. 19 20PAM_SSH MODULE REMOVED 21---------------------- 22 23The pam_ssh(8) have been removed from base to DPorts security/pam_ssh. 24 25UTMP LEGACY API REMOVED 26----------------------- 27 28The legacy "utmp" API (getutent() and friends, utmp.h, etc.) has been 29removed, and we are now using the POSIX "utmpx" API (getutxent(), 30utmpx.h, etc.) only. The most visible change for users is that the 31/var/log/wtmp file will no longer be written to, just /var/log/wtmpx. 32The wtmpcvt(1) utility is provided to convert old wtmp format files to 33wtmpx. 34 35To not break old applications, the utmp symbols are still provided by 36libc as dummy functions that do nothing and always succeed. 37 38TIMED AND TIMEDC REMOVED 39------------------------ 40 41timed(8) and timedc(8) have been removed because they are beyond 42obsolete for setting the time. 43 44LIBOPIE, LIBMD REMOVED 45---------------------- 46 47Removal of OPIE requires /etc/pam.d/ configs to be updated. 48 49+-----------------------------------------------------------------------+ 50+ UPGRADING DRAGONFLY FROM 5.4 TO LATER VERSIONS + 51+-----------------------------------------------------------------------+ 52 53GCC50 REMOVED 54------------- 55 56The GCC50 compiler has been retired. It has been replaced by a GCC80. 57The default alternative compiler has stayed the same - GCC47. 58 59 60PUFFS, PUTTER AND LIBREFUSE REMOVED 61----------------------------------- 62 63The puffs(4)/putter(4) subsystem has been removed, along with librefuse, 64libpuffs, and the mount_psshfs(8) utility. All of these have never been 65working correctly. 66 67FFS_ROOT OPTION REMOVED 68----------------------- 69 70The FFS_ROOT kernel configuration option has been finally removed, after 71having been a no-op since 4.9. That means users using a custom kernel 72configuration file that still contains it need to remove the option from 73that file. 74 75+-----------------------------------------------------------------------+ 76+ UPGRADING DRAGONFLY FROM 5.2 TO LATER VERSIONS + 77+-----------------------------------------------------------------------+ 78 79DIGI, RP AND SI DRIVERS REMOVED 80------------------------------- 81 82The digi(4), rp(4) and si(4) serial drivers have been removed. None of 83them were in our default kernel configuration file. The sicontrol(8) 84utility was removed, too. 85 86MKINITRD COMMAND REMOVED 87------------------------ 88 89The mkinitrd(8) command is removed and its functionality is replaced by 90the new "initrd" make target. After rebooting into the new world and 91verifying everything works, execute "make initrd" to upgrade the rescue 92tools and initrd image. 93 94IPSEC, IPSEC_ESP AND IPSEC_DEBUG REMOVED FROM VKERNEL64 CONFIG 95-------------------------------------------------------------- 96 97IPsec has been removed from the system. Of our standard kernel 98configurations, only the virtual kernel one had it. People running 99vkernels with configuration files derived from our VKERNEL64 will 100have to remove these options manually. 101 102+-----------------------------------------------------------------------+ 103+ UPGRADING DRAGONFLY FROM 5.0 TO LATER VERSIONS + 104+-----------------------------------------------------------------------+ 105 106VIRTIO_PCI REMOVED FROM KERNEL CONFIG 107------------------------------------- 108 109The "device virtio_pci" line in X86_64_GENERIC has been removed. People 110with configuration files derived from it have to remove it manually. 111 112VARIOUS 'R' COMMANDS AND DAEMONS REMOVED 113---------------------------------------- 114 115rcp(1), rlogin(1), rlogind(8), rsh(1) and rshd(8) have been removed. 116For those that still need them, there is the net/bsdrcmds port. 117 118VARIOUS FORMER OPTIONS REMOVED 119------------------------------ 120 121Various former kernel configuration options which had been no-ops for 122some time were completely removed: SYSVMSG, SYSVSEM, SYSVSHM, P1003_1B, 123_KPOSIX_VERSION and DSCHED_FQ. Users that have any of these still in 124their kernel configuration files have to remove them. 125 126BOOTSTRAPPING LIMITED FROM PRE 4.4 127---------------------------------- 128 129Upgrading to 5.1 and later versions now require at least 4.4 in 130preparations for upcoming base compilers updates. 131 132IF_PPP, PPPD, IF_FAITH, AND FAITHD REMOVED 133------------------------------------------ 134 135if_ppp has been replaced by "user ppp", i.e. ppp(8) and tun(4). It had 136already been removed from our default kernel configuration before 5.0, 137so only people with custom configurations based on earlier X86_64_GENERIC 138will have to remove it manually. 139 140The faith(4) interface has been completely removed after it had also 141been removed from our default kernel configuration. 142 143+-----------------------------------------------------------------------+ 144+ UPGRADING DRAGONFLY FROM 4.8 TO LATER VERSIONS + 145+-----------------------------------------------------------------------+ 146 147FFS_ROOT OPTION DISABLED 148------------------------ 149 150The FFS_ROOT option has been made a no-op and will be completely removed 151at some point in the future. Users with a custom kernel configuration 152can remove this option from it now. 153 154+-----------------------------------------------------------------------+ 155+ UPGRADING DRAGONFLY FROM 4.6 TO LATER VERSIONS + 156+-----------------------------------------------------------------------+ 157 158DSA OPENSSH KEYS DEPRECATED 159--------------------------- 160 161Note that DSA OpenSSH keys were deprecated in the 4.6 to 4.8 release. 162If you are upgrading from a release older than 4.8 and use DSA OpenSSH 163keys, please update your private/public key pair or risk locking 164yourself out. 165 166AHC, AHD, AIC, NCV, NSP AND STG DRIVERS REMOVED 167----------------------------------------------- 168 169They were all in our X86_64_GENERIC kernel configuration file, along with 170the AHC_REG_PRETTY_PRINT and AHD_REG_PRETTY_PRINT options, so any custom 171configuration files derived from it need adjustment. 172 173PORTAL FILE SYSTEM REMOVED 174-------------------------- 175 176It has been broken for a long time now. 177 178BINUTILS 2.27 REPLACES 2.24, PRIMARY 179------------------------------------ 180 181The oldest of the two versions of Binutils, version 2.24, was removed 182and replaced with Binutils 2.27. It becomes the primary version version 183of binutils and version 2.25 becomes the alternate. 184 185The accepted values of BINUTILSVER are now "binutils227" (default) and 186"binutils225". The building of Binutils 2.25 can be prevented by setting 187NO_ALTBINUTILS=yes in make.conf. 188 189COMPAT_43 KERNEL OPTION REMOVED 190------------------------------- 191 192It was commented out in our default configs for several years now, but 193might still be present in custom configs created before Nov. 2011. 194 195OPENSSL REMOVED 196--------------- 197 198OpenSSL has been removed from base and replaced with a private version of 199LibreSSL. The previously installed OpenSSL libraries, headers, and man 200pages will remain on the system unless the "make upgrade" command is 201specifically instructed to remove them. To do this, define 202REMOVE_OPENSSL_FILES for the upgrade command, e.g. 203"make upgrade REMOVE_OPENSSL_FILES=yes" 204 20528-Oct-2016: openssl has been replaced by ressl. It is recommended that any 206stale OpenSSL files be removed to avoid configuration scripts from using 207the stale and potentially vulnerable version, but all binaries that are 208dynamically linked to the OpenSSL libraries should be rebuilt first to 209avoid breakage. 210 211OPENSSH HPN REMOVED 212------------------- 213 214It has become too cumbersome to maintain HPN patches in OpenSSH in base. 215To use OpenSSH in base remove HPN config, if you have added it. 216Check files below for HPN config, see a few lines below. 217 /etc/ssh/ssh_config, /etc/ssh/sshd_config, ~/.ssh/config 218sshd(8) will fail to start if HPN config is used. 219 220NOTE: HPN config in sshd_config will prohibit remote access to host using ssh. 221 222HPN config: 223HPNDisabled 224HPNBufferSize 225TcpRcvBuf 226TcpRcvBufPoll 227NoneEnabled 228NoneSwitch 229cipher MTR-AES-CTR 230cipher NONE 231 232OpenSSH HPN is a patch set to OpenSSH providing higher performance under some 233circumstances, especially for networking. 234If HPN functionality is needed, install security/openssh from dports. 235 236CS, EX AND VX DRIVERS REMOVED 237----------------------------- 238 239The cs(4), ex(4) and vx(4) drivers have been removed. They were very 240old and its doubtful they ever worked properly in x86_64 but they were 241in X86_64_GENERIC, so custom configurations derived from it have to be 242adjusted. 243 244+-----------------------------------------------------------------------+ 245+ UPGRADING DRAGONFLY FROM 4.4 TO LATER VERSIONS + 246+-----------------------------------------------------------------------+ 247 248AMD REMOVED 249----------- 250 251The am-utils automounter suite has been removed. It stopped working 252at some point and was never fixed. autofs(5) and the associated 253userland has been brought in from FreeBSD and replaces it. 254 255AN DRIVER REMOVED 256----------------- 257 258The an(4) driver has been removed. It was in the X86_64_GENERIC kernel 259config file, so any configurations derived from it have to be adjusted. 260 261/DEV/DRI GROUP CHANGED 262---------------------- 263 264The default group assigned to /dev/dri entries has been changed 265from 'wheel' to 'video' with the id of '44'. If you want to have 266access to the dri devices please add yourself to the video group 267with: 268 269# pw groupmod video -m $USER 270 271+-----------------------------------------------------------------------+ 272+ UPGRADING DRAGONFLY FROM 4.2 TO LATER VERSIONS + 273+-----------------------------------------------------------------------+ 274 275DSCHED REMOVED 276-------------- 277 278dsched(4) has been removed and one of its kernel options, DSCHED_FQ, was 279in our default kernel config file. So the DSCHED_FQ option has been turned 280into a no-op for now and can be removed from custom configurations. 281 282EST DRIVER REMOVED, COMPILE_ET AND LIBCOM_ERR TOO 283------------------------------------------------- 284 285The est(4) driver has been removed. All CPUs it supported (except one) 286were 32 bits only. Those who are still using the Core 2 Duo T7500 should 287report back if there are any issues with this CPU and our regular ACPI 288P-state support. 289 290Also, compile_et(1) and com_err(3) have been removed as well. They 291should have been removed along with kerberos support, back in 2009. 292 293SEVERAL LOCALES RENAMED 294----------------------- 295 296Several locales were using obsolete and misleading names, and thus have 297been adjusted to current standards. Any users of the following locales 298need to select alternates: 299 300DFLY 4.2 locale DFLY 4.4 alterative locale 301--------------- ------------------------------------ 302mn_MN.UTF-8 mn_Cyrl_MN.UTF-8 303no_NO.UTF-8 nb_NO.UTF-8 or nn_NO.UTF-8 304no_NO.ISO8859-1 nb_NO.ISO8869-1 or nn_NO.ISO8859-1 305no_NO.ISO8859-15 nb_NO.ISO8859-15 or nn_NO.ISO8859-15 306sr_YU.UTF-8 sr_Cyrl_RS.UTF-8 or sr_Latn_RS.UTF-8 307sr_YU.ISO8859-5 sr_Cyrl_RS.ISO8859-5 308sr_YU.ISO8859-2 sr_Latn_RS.ISO8859-2 309zh_CN.GBK zh_Hans_CN.GBK 310zh_CN.UTF-8 zh_Hans_CN.UTF-8 311zh_CN.eucCN zh_Hans_CN.eucCN 312zh_CN.GB2312 zh_Hans_CH.GB2312 313zh_CN.GB18030 zh_Hans_CH.GB18030 314zh_HK.Big5HKSCS zh_Hant_HK.Big5HKSCS 315zh_HK.UTF_8 zh_Hant_HK.UTF-8 316zh_TW.Big5 zh_Hant_TW.Big5 317zh_TW.UTF-8 zh_Hant_TW.UTF-8 318 319+-----------------------------------------------------------------------+ 320+ UPGRADING DRAGONFLY FROM 4.0 TO LATER VERSIONS + 321+-----------------------------------------------------------------------+ 322 323BINUTILS 2.25 REPLACES 2.22, PRIMARY 324------------------------------------ 325 326The oldest of the two versions of Binutils, version 2.22, was removed 327and replaced with Binutils 2.25. It becomes the primary version version 328of binutils and version 2.24 becomes the alternate. There are 8 current 329CVE written against 2.24, so for security reasons version 2.25 should 330always be used. 331 332The accepted values of BINUTILSVER are now "binutils225" (default) and 333"binutils224". The building of Binutils 2.24 can be prevented by setting 334NO_ALTBINUTILS=yes in make.conf. 335 336LOADER OPTIONS CHANGED 337---------------------- 338 339Right after the development branch started, the Fred art accompanying the 340loader menu was improved. The line between Fred and the menu was removed 341by default (but can optionally be returned) and the placement shifted as 342a result. The drawing was improved, and the colored version was improved, 343changing the eyes and wing color from white to red. A new color version 344of Fred was added, one with a blue scheme. 345 346The loader menu defaults have changed since release 4.0: The vertical 347line was removed, the loader is displayed in color by default*, and the 348blue scheme is used. 349 350The loader.conf changes are: 351loader_color: option has been removed 352loader_plain: option has been added, it changed menu to monochrome 353fred_is_red: changes color scheme from blue to red 354fred_is_blue: option existed only on 4.1, it has been removed 355fred_separated: Adds line between Fred and menu (as seen previously) 356 357* If loader.conf defines "console" as "comconsole" or "console" is defined 358 in the environment as "comconsole" then color will not be displayed, 359 even if loader_plain value is "NO". 360 361SENDMAIL REMOVED FROM BASE 362-------------------------- 363 364The only Mail Transfer Agent provided now is DragonFly Mail Agent (dma). 365If the system being upgraded is still configured to use the sendmail 366binaries from base, the "make upgrade" command will fail. 367 368The administrator must change /etc/mail/mailer.conf to switch the 369mailwrapper to dma or a DPorts-based MTA prior to running the upgrade 370command that permanently removes sendmail executables and could 371potentially break a running mail server. 372 373Refer: http://www.dragonflybsd.com/docs/docs/newhandbook/mta/ for 374detailed instructions on how to configure the MTA selection. 375 376_KPOSIX_VERSION and P1003_1B OPTIONS REMOVED 377-------------------------------------------- 378 379The _KPOSIX_VERSION and P1003_1B kernel options have been changed to 380no-ops. They can be removed from custom kernel configurations. 381 382SOUND SYSTEM UPDATED FROM FreeBSD 11-CURRENT 383-------------------------------------------- 384 385Many more sound devices may be detected. 386 387If the default device choosen isn't to your liking, setting the sysctl 388hw.snd.default_unit to a different number will change it. 389 390SCTP SUPPORT DROPPED 391-------------------- 392 393Support for the SCTP protocol has been removed. 394 395OLD USB DRIVERS REMOVED 396----------------------- 397 398The old USB stack, along with the kernel config option "device oldusb" 399and the make.conf variable "WANT_OLDUSB" have been removed. This means 400that for custom kernel configuration files which were derived from a 401GENERIC or X86_64_GENERIC file prior to making the usb4bsd stack default, 402various (old USB stack specific) devices will now complain about being 403unknown: 404 405 * oldusb (obviously) 406 * natausb (not yet ported to usb4bsd) 407 * rue (not yet ported to usb4bsd) 408 * ugen (no longer needed in usb4bsd) 409 * urio (not yet ported to usb4bsd) 410 * uscanner (no longer needed in usb4bsd) 411 412They should be removed or commented out in such custom kernel configs. 413 414GCC 5 415----- 416 417The GCC 4.4 compiler has been retired. It has been replaced by a GCC 5.1. 418The following make.conf variables no longer work: NO_GCC44, NO_OBJC, and 419NO_CXX. The latter was never documented and the latest versions of GCC are 420partially written in C++ so a C++ compiler is no longer optional. In 421practical terms it has not been optional for many years as other base 422components are also written in C++. The resource savings by avoiding 423building Objective-C compiler is so small, the complexity added by NO_OBJC 424internally was deemed a bad tradeoff so that is the reason for its removal. 425Also note that no "info" pages are installed with GCC 5. After this entry 426was originally written, all info pages were removed from DragonFly. 427 428GCC 5.1 has been designated as the primary compiler. As such, there is a 429new make.conf variable, NO_ALTCOMPILER. It will block the rebuilding of 430the designated secondary compiler, GCC 4.7. However, while DPorts 431primarily uses GCC 5 to build ports now, it still uses GCC 4.7 as well, so 432if building ports from source is desired, don't block building of the 433secondary compiler. 434 435+-----------------------------------------------------------------------+ 436+ UPGRADING DRAGONFLY FROM 3.8 TO LATER VERSIONS + 437+-----------------------------------------------------------------------+ 438 439SMP AND DEVICE_POLLING OPTIONS MADE UNKNOWN 440------------------------------------------- 441 442DEVICE_POLLING was replaced by IFPOLL_ENABLE and the former SMP code is 443the default now (even on single-core systems), both for, like, 21 months. 444We kept the options around as no-ops as a convenience, to allow people 445using the same config for the then current release and the then current 446master. That period is now over, so any configs still having those 447options have to be adjusted. 448 449SYSVIPC SYSCALLS MADE NON-OPTIONAL 450---------------------------------- 451 452The code related to the SYSVMSG, SYSVSEM and SYSVSHM kernel options is 453now compiled in by default. The options are no-ops for now. 454 455DEFAULT DRIVER CHANGED FOR LSI "THUNDERBOLT" SERIES RAID CONTROLLERS 456-------------------------------------------------------------------- 457 458The default driver for those controllers is now mrsas(4) due to reports 459of file system corruption using the mfi(4) driver. The whole issue (and 460how to deal with potential problems when switching) was explained here: 461 462http://lists.dragonflybsd.org/pipermail/users/2014-July/128703.html 463 464A tunable is provided for letting those controllers still attach via 465the mfi(4) driver, hw.mrsas.mfi_enable (see mrsas(4) manual page). 466 467OLDER NETWORK DRIVERS MOVED TO I386 ONLY 468---------------------------------------- 469 470The following drivers have been made i386 only: ed(4), sr(4), ng_sync_ar 471and ng_sync_sr. ed(4) used to be in X86_64_GENERIC, so it has to be 472removed in kernel configs derived from X86_64_GENERIC. 473 474+-----------------------------------------------------------------------+ 475+ UPGRADING DRAGONFLY FROM 3.6 TO LATER VERSIONS + 476+-----------------------------------------------------------------------+ 477 478UPDATE FROM MOST RECENT 3.6 479--------------------------- 480 481Versions of 3.6 built before June 25th have a bug where installworld might 482crash during installation of the new initrd. Upgrade to the latest version 483of 3.6 before updating to 3.8 or later. 484 485ATM, IPX, NCP AND NWFS SUPPORT DROPPED 486-------------------------------------- 487 488Support for the IPX and NCP network protocols and for mouting NetWare 489file systems has been dropped. Dito for ATM protocol support. 490 491INITRD IMAGES NOW INSTALLED BY DEFAULT 492-------------------------------------- 493 494An initial ramdisk image is now installed in /boot/kernel/initrd.img.gz 495 496Older images installed under the file name of initrd.img will be removed 497automatically by the make upgrade process. 498 499USB4BSD IS NOW THE DEFAULT USB STACK 500------------------------------------ 501 502To get back to the old stack, put "WANT_OLDUSB=yes" in /etc/make.conf and 503replace "device usb" with "device oldusb" in the kernel configuration. 504 505MORE ISA SUPPORT DROPPED 506------------------------ 507 508ISA support has been dropped from the following drivers: adv(4), an(4), 509ar(4), cs(4), digi(4), ed(4), ep(4), ex(4), fe(4), lnc(4), sbni(4), 510si(4), sn(4), and stg(4). 511 512+-----------------------------------------------------------------------+ 513+ UPGRADING DRAGONFLY FROM 3.4 TO LATER VERSIONS + 514+-----------------------------------------------------------------------+ 515 516ABI CHANGE 517---------- 518 519Installed third-party software (dports) will have to be rebuilt after upgrade, 520or reinstalled from binary packages. 521 522UPDATING FROM 3.4 TO 3.6 523------------------------ 524 525This only applies for this specific upgrade due to locale changes; it is 526not needed for upgrades after 3.6. Please update in this order: 527 528make buildworld 529make buildkernel 530make installworld 531make installkernel 532*reboot* 533make upgrade 534 535See this mailing list post for details: 536http://lists.dragonflybsd.org/pipermail/users/2013-September/090163.html 537 538CYRIX OPTIONS REMOVED 539--------------------- 540 541The following Cyrix related options have been removed: CPU_BTB_EN, 542CPU_CYRIX_NO_LOCK, CPU_DIRECT_MAPPED_CACHE, CPU_DISABLE_5X86_LSSER, 543CPU_FASTER_5X86_FPU, CPU_IORT, CPU_LOOP_EN, CPU_RSTK_EN, CPU_SUSP_HLT, 544CYRIX_CACHE_WORKS, and CYRIX_CACHE_REALLY_WORKS 545 546ISA SUPPORT REMOVED FROM RP(4) 547------------------------------ 548 549ISA support has been removed from the rp(4) driver. It is now PCI only. 550 551+-----------------------------------------------------------------------+ 552+ UPGRADING DRAGONFLY FROM 3.2 TO LATER VERSIONS + 553+-----------------------------------------------------------------------+ 554 555COMPAT_SUNOS OPTION REMOVED 556--------------------------- 557 558The COMPAT_SUNOS option has been removed. It was meant to provide binary 559compatibility with SunOS 4.x for the sparc32 port of 4.4BSD. 560 561ISA SOUND CARD SUPPORT REMOVED 562------------------------------ 563 564The following modules have been removed (all for ISA sound cards): 565snd_ad1816.ko, snd_ess.ko, snd_mss.ko, snd_sb8.ko, snd_sb16.ko, snd_sbc.ko 566 567GCC 4.7 568------- 569 570DragonFly has switched base compilers. GCC 4.7 is now the default 571compiler and GCC 4.4 is the alternative compiler. The "NO_GCC47" make 572variable ceases to work now. 573 574Users who wish to build only GCC 4.7 have to use NO_GCC44 in the 575/etc/make.conf to prohibit GCC 4.4 from building. However, using it is 576highly discouraged. There are a few packages in pkgsrc that do not build 577with GCC 4.7 and the new "DPorts" system uses GCC 4.4 by default. At 578this time, it is recommended to keep both compilers on the base system. 579 580SMP OPTION REMOVED 581------------------ 582 583The SMP kernel option has been made a no-op. All kernels now feature SMP 584support. If you have 'options SMP' in your kernel config, you can as well 585remove it. 586 587DEVICE_POLLING OPTION REPLACED BY IFPOLL_ENABLE OPTION, KTR_POLLING REMOVED 588--------------------------------------------------------------------------- 589 590The DEVICE_POLLING kernel option has been made a no-op and it has been 591replaced by IFPOLL_ENABLE. If you have 'options DEVICE_POLLING' in your 592kernel config, you need to change it to IFPOLL_ENABLE. 593 594Also, the KTR_POLLING kernel option has been removed, so it must be 595removed from kernel configs that have it. 596 597BUSLOGIC, CYCLADES AND STALLION ISA SUPPORT REMOVED 598--------------------------------------------------- 599 600The bt(4) driver for Buslogic SCSI adapters has been made PCI only. ISA 601cards will no longer be detected. 602 603The same has been done for Stallion multiport serial controllers. stli(4) 604has been completely removed (along with the stlload(8) and stlstty(8) 605utilities) and stl(4) was changed to support only PCI cards. Similarly, 606ISA support was removed from cy(4) too. All these drivers are i386 only. 607 608COMPAT_OLDISA OPTION GONE 609------------------------- 610 611The i386 specific COMPAT_OLDISA kernel option has been removed, since 612nothing needs it anymore. 613 614+-----------------------------------------------------------------------+ 615+ UPGRADING DRAGONFLY FROM 3.0 TO LATER VERSIONS + 616+-----------------------------------------------------------------------+ 617 618APIC_IO OPTION REMOVED 619---------------------- 620 621The APIC_IO kernel option is no longer accepted after having been without 622effect for a while. The hw.ioapic_enable tunable now serves its purpose. 623If you have 'options APIC_IO' in your kernel config, you'll have to 624remove it. 625 626WATCHDOG_ENABLE & HW_WDOG OPTIONS REMOVED 627----------------------------------------- 628 629The wdog framework is now compiled into our kernels by default, so the 630options are no longer needed. 631 632DOSCMD(1) REMOVED 633----------------- 634 635doscmd(1) has been removed. It was i386 only. The doscmd(1) specific 636NO_X make.conf option was removed too. 637 638GCC 4.7 639------- 640 641GCC 4.7 has been brought in and replaces GCC 4.1 as DragonFly's non- 642default compiler in base (default is still GCC 4.4). 643 644Users who wish to build only GCC 4.4 have to replace NO_GCC41 with 645NO_GCC47 in /etc/make.conf. 646 647USB4BSD 648------- 649 650A new USB stack (from FreeBSD) has been brought in. The following 651modules have been ported so far: usb, uhci, ohci, ehci, xhci, umass, 652usfs, uether, if_axe, if_udav, ukbd, ums, uep, uhid, usb_quirk, 653and uaudio. 654 655It is not yet the default. To activate it, WANT_USB4BSD=yes has to 656be put in make.conf and device "usb4bsd" (quotes needed) has to 657replace device usb in the kernel config. After that, a full 658build/install/upgrade cycle is needed. 659 660Note that this is experimental and incomplete, but we are interested 661in hearing about issues with it, of course. 662 663ISA SUPPORT REMOVED FROM AIC-6260/6360 DRIVER 664--------------------------------------------- 665 666ISA adapter support was dropped from the aic(4) driver. 667 668+-----------------------------------------------------------------------+ 669+ UPGRADING DRAGONFLY FROM 2.10 TO LATER VERSIONS + 670+-----------------------------------------------------------------------+ 671 672SEVERAL ISA DRIVERS REMOVED 673--------------------------- 674 675The following ISA only drivers have been removed along with a couple of 676associated userland tools: 677 678aha(4) 679asc(4) & sasc(1) 680ctx 681dgb(4) 682el(4) 683gpib 684gsc(4) & sgsc(1) 685ie(4) 686labpc(4) 687le(4) 688mse(4) 689rc(4) 690rdp(4) 691spigot 692tw(4) & xten(1) & xtend(8) 693wl(4) & wlconfig(8) 694wt(4) 695 696Note that two of these drivers (aha(4) and ie(4)) are in our GENERIC 697config and one (aha(4)) is in our X86_64_GENERIC kernel configuration 698file. 699 700If buildkernel complains about any of these drivers, just remove them 701from your kernel configuration. 702 703BINUTILS 2.20 704------------- 705Binutils 2.20 has been removed in favor of Binutils 2.22. The accepted 706values of BINUTILSVERS are now binutils221 and binutils222 (default). 707 708BUILDWORLD/-KERNEL PARALLELIZATION WORK 709--------------------------------------- 710Due to changes in the way we build with more than one make job, you 711will have to update install(1) and mkdir(1) prior to buildworld if you 712want to build with 'make -j': 713 714cd /usr/src/usr.bin/xinstall; make; make install; make clean 715cd /usr/src/bin/mkdir; make; make install; make clean 716 717DMA(8) UPGRADE 718-------------- 719dma(8) has been upgraded to v0.7 which no longer supports the 720/etc/dma/virtusertable. Some of its functionality has been replaced 721with the MASQUERADE keyword and the EMAIL environment variable (see 722the dma(8) manual page). 723 724+-----------------------------------------------------------------------+ 725+ UPGRADING DRAGONFLY FROM 2.8 TO LATER VERSIONS + 726+-----------------------------------------------------------------------+ 727 728GCC 4.4 & BINUTILS 2.21 729----------------------- 730 731GCC 4.4 has been made DragonFly's default compiler and Binutils 2.21 has 732been made DragonFly's default Binutils. 733 734That means that any settings that set CCVER to 'gcc44' are not needed 735anymore. Instead, CCVER can be set to 'gcc41' to go back to using 736GCC 4.1. 737 738It also means that 'binutils221' as a value for BINUTILSVER has no 739effect anymore. 2.17 has been removed and 'binutils220' is available 740as an option. 741 742The NO_GCC44 option has been removed and will not affect the build 743anymore. There is now a NO_GCC41 option that will prevent GCC 4.1 from 744building in a similar fashion. 745 746Note that you must do a full buildworld/buildkernel for upgrading. 747 748pkg_radd settings 749----------------- 750 751The config file for pkg_radd has moved from /etc/settings.conf to 752/etc/pkg_radd.conf. Save the contents of settings.conf before upgrading 753if this is needed. This warning only applies if /etc/settings.conf 754exists. pkg_radd will continue to work with defaults. 755 756+-----------------------------------------------------------------------+ 757+ 20100927 + 758+ UPGRADING DRAGONFLY FROM 2.6 to 2.8 or HEAD + 759+-----------------------------------------------------------------------+ 760 761OpenSSL 762-------- 763 764OpenSSL has been upgraded, and SHLIB_MAJOR was bumped for libssh and libcrypto. 765This shouldn't break any 3rd-party software, but you'll need to recompile your 7663rd-party software if you want it to link against the new version of OpenSSL. 767 768Loader 769------- 770 771A new loader (dloader) has been added which better handles booting from 772multiple kernel/module versions. 773 774To upgrade (Only for this upgrade, for post 2.8 upgrades see GENERAL below) 775 776 cd /usr/src 777 make buildworld 778 make installworld 779 make upgrade 780 make buildkernel KERNCONF=<KERNELNAME> 781 make installkernel KERNCONF=<KERNELNAME> 782 783Note that you must installworld and run the 'upgrade' target before 784installing the new kernel. 785 786BIND 787----- 788 789BIND has been removed from the base system. The ldns and drill tools have 790been added for basic functionality. Use 'drill' where you would normally 791use nslookup or dig, or install BIND from pkgsrc. It's available as 792net/bind95, net/bind96, or net/bind97 as of this writing. 793 794This only affects older systems upgrading to 2.8. New 2.8+ installs 795include BIND as a pkgsrc package. 796 797+-----------------------------------------------------------------------+ 798+ UPGRADING DRAGONFLY ON AN EXISTING DRAGONFLY SYSTEM + 799+ GENERAL + 800+-----------------------------------------------------------------------+ 801 802Instructions on how to obtain and maintain DragonFly source code using git 803are in the development(7) manual page. 804 805To upgrade a DragonFly system from sources you run the following sequence: 806 807 cd /usr/src 808 make buildworld 809 make buildkernel KERNCONF=<KERNELNAME> 810 make installkernel KERNCONF=<KERNELNAME> 811 make installworld 812 813You will also want to run the 'upgrade' target to upgrade your /etc and the 814rest of your system. The upgrade target is aware of stale files created by 815older DragonFly installations and should delete them automatically. 816 817 make upgrade 818 819See the build(7) manual page for further information. 820 821Once you've done a full build of the world and kernel you can do incremental 822upgrades of either by using the 'quickworld' and 'quickkernel' targets 823instead of 'buildworld' and 'buildkernel'. If you have any problems with 824the quick targets, try updating your repo first, and then a full buildworld 825and buildkernel as shown above, before asking for help. 826 827+-----------------------------------------------------------------------+ 828+ UPGRADING FROM DRAGONFLY <= 2.0 TO DRAGONFLY >= 2.1 + 829+-----------------------------------------------------------------------+ 830 831In 2.1 kernel and modules has moved to boot directory. For most cases 832this is handled automatically by 'make upgrade'. A few cases needs manual 833intervention: 834 835 * When installing a kernel without first doing a make buildworld, 836 installworld and upgrade to the same DESTDIR as kernel: 837 make DESTDIR/boot directory and move kernel and modules into this boot 838 directory; also move kernel.old and modules.old. 839 Typical example is vkernel(7), use (no modules used): 840 841 cd /var/vkernel 842 mkdir boot 843 chflags noschg kernel 844 mv kernel kernel.old boot 845 chflags schg boot/kernel 846 847 * When using a boot-only partition, /boot/loader.rc needs to be edited: 848 delete occurrences of '/boot/'. 849 These occurences can normally be deleted in any case, see loader(8). 850 851+-----------------------------------------------------------------------+ 852+ UPGRADING FROM DRAGONFLY <= 1.8 TO DRAGONFLY >= 1.9 + 853+-----------------------------------------------------------------------+ 854 855In 1.9 major changes to the disk management infrastructure have taken 856place. make upgrade may not catch all of your disk devices in /dev, 857so after upgrading be sure to cd /dev; ./MAKEDEV <blah> where <blah> 858are all of your disk devices. HOWEVER, from late 2.3 on we run devfs 859and MAKEDEV no longer exists. 860 861The biggest changes in 1.9 are: 862 863(1) That whole-slice devices such as da0s1 no longer share the same device 864 id as partition c devices such as da0s1c. 865 866(2) The whole-disk device (e.g. da0) is full raw access to the disk, 867 with no snooping or reserved sectors. Consequently you cannot run 868 disklabel on this device. Instead you must run disklabel on a 869 whole-slice device. 870 871(3) The 'compatibility' partitions now use slice 0 in the device name, 872 so instead of da0a you must specify da0s0a. Also, as per (1) above, 873 accessing the disklabel for the compatibility partitions must be 874 done via slice 0 (da0s0). 875 876(4) Many device drivers that used to fake up labels, such as CD, ACD, VN, 877 and CCD now run through the disk management layer and are assigned 878 real disk management devices. VN and CCD in particular do not usually 879 use a MBR and disklabels must be accessed through the compatibility 880 slice 0. Your /etc/ccd.conf file still specifies 'ccd0', though, you 881 don't name it 'ccd0s0' in the config file. 882 883Generally speaking, you have to get used to running fdisk and disklabel on 884the correctly specified device names. A lot of the wiggle, such as running 885disklabel on a partition, has been removed. 886 887+-----------------------------------------------------------------------+ 888+ UPGRADING FROM OLDER VERSIONS OF DRAGONFLY OR FREEBSD + 889+-----------------------------------------------------------------------+ 890 891> Kerberos IV 892------------- 893 894Kerberos IV (eBones) was removed from the tree, please consider moving to 895Kerberos 5 (Heimdal). 896 897> Package Management System 898--------------------------- 899 900Starting with the 1.4 release, DragonFly uses NetBSD's pkgsrc package 901management system. The necessary tools to build and maintain packages 902are provided in /usr/pkg/bin and /usr/pkg/sbin. Make sure that these 903directories are in your PATH variable. 904 905In order to obtain a reasonably current snapshot of the pkgsrc tree, use 906the tarball from NetBSD: 907 908 fetch -o /tmp/pkgsrc.tar.gz ftp://ftp.NetBSD.org/pub/NetBSD/packages/pkgsrc.tar.gz 909 cd /usr; tar -xzf /tmp/pkgsrc.tar.gz; chown -R root:wheel pkgsrc 910 911This tree can then be kept up to date with cvs update: 912 913 cd /usr/pkgsrc; cvs up 914 915NOTE! If you upgraded from a pre-1.4 system to 1.4 or later, you need to 916build and install the pkgsrc bootstrap manually: 917 918 cd /usr/pkgsrc/bootstrap 919 ./bootstrap --pkgdbdir /var/db/pkg --prefix /usr/pkg 920 921+-----------------------------------------------------------------------+ 922+ UPGRADING DRAGONFLY ON AN EXISTING DRAGONFLY SYSTEM + 923+ UPDATING FROM PRE-1.2 SYSTEMS OR FreeBSD 4.x TO + 924+ DRAGONFLY 1.3+ (EITHER PREVIEW or HEAD) + 925+-----------------------------------------------------------------------+ 926 927The compatibility shims for the build environment have been removed, you 928have to update to DragonFly 1.2 release branch first. 929 930The default PAM configuration has moved from /etc/pam.conf to /etc/pam.d/. 931The existing configuration can be converted using /etc/pam.d/convert.sh. 932Entries in /etc/pam.d/ override entries in /etc/pam.conf. In addition 933the pam_skey.so module was retired, you have to remove it manually from 934your configuration, when you convert it. 935 936> Required user and group IDs when upgrading from either FreeBSD or DragonFly 937--------------------- 938 939The following users may be missing from your password file. Use vipw and 940add any that are missing: 941 942smmsp:*:25:25::0:0:Sendmail Submission User:/var/spool/clientmqueue:/sbin/nologin 943_pflogd:*:64:64::0:0:pflogd privsep user:/var/empty:/sbin/nologin 944 945The following groups may be missing from your group file. Use vi /etc/group 946and add any that are missing: 947 948smmsp:*:25: 949authpf:*:63: 950_pflogd:*:64: 951 952 953> Upgrading to DragonFly from FreeBSD 954--------------------- 955 956You can build the DragonFly world and DragonFly kernels on a FreeBSD-4.x or 957FreeBSD-5.x machine and then install DragonFly over FreeBSD, replacing 958FreeBSD. Note that the DragonFly buildworld target does not try to reuse 959make depend information, it starts from scratch, so no pre-cleaning of the 960object hierarchy is necessary. 961 962 # get the CVS repository (it is placed in /home/dcvs, 500MB). 963 # Please use the -h option and a mirror site to pull the 964 # initial repository, but feel free to use the main repository 965 # machine to pull updates. 966 cvsup /usr/share/examples/cvsup/DragonFly-cvs-supfile 967 # install the source from the CVS hierarchy (remove preexisting 968 # FreeBSD src first) (500MB) 969 cd /usr 970 rm -rf src 971 cvs -R -d /home/dcvs checkout -P src 972 973 # build it (500MB used in /usr/obj) 974 # 975 cd /usr/src 976 make buildworld 977 make buildkernel KERNCONF=<KERNELNAME> 978 979Once you have built DragonFly you have to install it over FreeBSD. Since 980DragonFly does not track changes made by FreeBSD to its include file 981hierarchy and include file pollution can cause all sorts of unexpected 982compilation issues to come up, it is best to wipe your include hierarchy 983prior to installing DragonFly. Note that you should not wipe any installed 984FreeBSD header files or binaries until after you have successfully completed 985the build steps above. 986 987 rm -rf /usr/include 988 mkdir /usr/include 989 make installkernel KERNCONF=<KERNELNAME> 990 make installworld 991 992Then you need to upgrade your system. DragonFly's 'make upgrade' target 993will unconditionally upgrade the /etc files that sysops do not usually 994mess around with, such as the files in /etc/rc.d. It will also remove any 995obsolete files such as utilities and manpages that have been removed from 996the system since the version you're coming from. If you are unsure we 997recommend that you make a backup of at least your /etc before applying 998this step. Note that DragonFly's RC system is basically RCNG from 999FreeBSD-5, but there are some differences in the contents of the RC files. 1000 1001 make upgrade 1002 1003NOTE! Never do a 'make upgrade' before 'make installworld' has been run. 1004Doing so might leave your system in an unusable state. 1005 1006Finally we recommend that you do an 'ls -lta BLAH' for /bin, /sbin, /usr/bin, 1007/usr/bin, and /usr/lib, and remove any stale files that you find. Please 1008report these files to the DragonFly developers so that they can be added to 1009the 'upgrade' target. 1010 1011
