1 Updating Information for FreeBSD current users. 2 3This file is maintained and copyrighted by M. Warner Losh <imp@freebsd.org>. 4See end of file for further details. For commonly done items, please see the 5COMMON ITEMS: section later in the file. These instructions assume that you 6basically know what you are doing. If not, then please consult the FreeBSD 7handbook: 8 9 https://www.freebsd.org/doc/en_US.ISO8859-1/books/handbook/makeworld.html 10 11Items affecting the ports and packages system can be found in 12/usr/ports/UPDATING. Please read that file before running portupgrade. 13 14NOTE: FreeBSD has switched from gcc to clang. If you have trouble bootstrapping 15from older versions of FreeBSD, try WITHOUT_CLANG and WITH_GCC to bootstrap to 16the tip of head, and then rebuild without this option. The bootstrap process 17from older version of current across the gcc/clang cutover is a bit fragile. 18 19NOTE TO PEOPLE WHO THINK THAT FreeBSD 12.x IS SLOW: 20 FreeBSD 12.x has many debugging features turned on, in both the kernel 21 and userland. These features attempt to detect incorrect use of 22 system primitives, and encourage loud failure through extra sanity 23 checking and fail stop semantics. They also substantially impact 24 system performance. If you want to do performance measurement, 25 benchmarking, and optimization, you'll want to turn them off. This 26 includes various WITNESS- related kernel options, INVARIANTS, malloc 27 debugging flags in userland, and various verbose features in the 28 kernel. Many developers choose to disable these features on build 29 machines to maximize performance. (To completely disable malloc 30 debugging, define MALLOC_PRODUCTION in /etc/make.conf, or to merely 31 disable the most expensive debugging functionality run 32 "ln -s 'abort:false,junk:false' /etc/malloc.conf".) 33 3420180826: 35 The Yarrow CSPRNG has been removed from the kernel as it has not been 36 supported by its designers since at least 2003. Fortuna has been the 37 default since FreeBSD-11. 38 3920180822: 40 devctl freeze/thaw have gone into the tree, the rc scripts have been 41 updated to use them and devmatch has been changed. You should update 42 kernel, userland and rc scripts all at the same time. 43 4420180818: 45 The default interpreter has been switched from 4th to Lua. 46 LOADER_DEFAULT_INTERP, documented in build(7), will override the default 47 interpreter. If you have custom FORTH code you will need to set 48 LOADER_DEFAULT_INTERP=4th (valid values are 4th, lua or simp) in 49 src.conf for the build. This will create default hard links between 50 loader and loader_4th instead of loader and loader_lua, the new default. 51 If you are using UEFI it will create the proper hard link to loader.efi. 52 53 bhyve uses userboot.so. It remains 4th-only until some issues are solved 54 regarding coexisting with multiple versions of FreeBSD are resolved. 55 5620180815: 57 ls(1) now respects the COLORTERM environment variable used in other 58 systems and software to indicate that a colored terminal is both 59 supported and desired. If ls(1) is suddenly emitting colors, they may 60 be disabled again by either removing the unwanted COLORTERM from your 61 environment, or using `ls --color=never`. The ls(1) specific CLICOLOR 62 may not be observed in a future release. 63 6420180808: 65 The default pager for most commands has been changed to "less". To 66 restore the old behavior, set PAGER="more" and MANPAGER="more -s" in 67 your environment. 68 6920180731: 70 The jedec_ts(4) driver has been removed. A superset of its functionality 71 is available in the jedec_dimm(4) driver, and the manpage for that 72 driver includes migration instructions. If you have "device jedec_ts" 73 in your kernel configuration file, it must be removed. 74 7520180730: 76 amd64/GENERIC now has EFI runtime services, EFIRT, enabled by default. 77 This should have no effect if the kernel is booted via BIOS/legacy boot. 78 EFIRT may be disabled via a loader tunable, efi.rt.disabled, if a system 79 has a buggy firmware that prevents a successful boot due to use of 80 runtime services. 81 8220180727: 83 Atmel AT91RM9200 and AT91SAM9, Cavium CNS 11xx and XScale 84 support has been removed from the tree. These ports were 85 obsolete and/or known to be broken for many years. 86 8720180723: 88 loader.efi has been augmented to participate more fully in the 89 UEFI boot manager protocol. loader.efi will now look at the 90 BootXXXX environment variable to determine if a specific kernel 91 or root partition was specified. XXXX is derived from BootCurrent. 92 efibootmgr(8) manages these standard UEFI variables. 93 9420180720: 95 zfsloader's functionality has now been folded into loader. 96 zfsloader is no longer necessary once you've updated your 97 boot blocks. For a transition period, we will install a 98 hardlink for zfsloader to loader to allow a smooth transition 99 until the boot blocks can be updated (hard link because old 100 zfs boot blocks don't understand symlinks). 101 10220180719: 103 ARM64 now have efifb support, if you want to have serial console 104 on your arm64 board when an screen is connected and the bootloader 105 setup a frambuffer for us to use, just add : 106 boot_serial=YES 107 boot_multicons=YES 108 in /boot/loader.conf 109 For Raspberry Pi 3 (RPI) users, this is needed even if you don't have 110 an screen connected as the firmware will setup a framebuffer are that 111 u-boot will expose as an EFI framebuffer. 112 11320180719: 114 New uid:gid added, ntpd:ntpd (123:123). Be sure to run mergemaster 115 or take steps to update /etc/passwd before doing installworld on 116 existing systems. Also, rc.d/ntpd now starts ntpd(8) as user ntpd 117 if the new mac_ntpd(4) policy is available, unless ntpd_flags or 118 the ntp config file contain options that change file/dir locations. 119 When such options (e.g., "statsdir" or "crypto") are used, ntpd can 120 still be run as non-root by setting ntpd_user=ntpd in rc.conf, after 121 taking steps to ensure that all required files/dirs are accessible 122 by the ntpd user. 123 12420180717: 125 Big endian arm support has been removed. 126 12720180711: 128 The static environment setup in kernel configs is no longer mutually 129 exclusive with the loader(8) environment by default. In order to 130 restore the previous default behavior of disabling the loader(8) 131 environment if a static environment is present, you must specify 132 loader_env.disabled=1 in the static environment. 133 13420180705: 135 The ABI of syscalls used by management tools like sockstat and 136 netstat has been broken to allow 32-bit binaries to work on 137 64-bit kernels without modification. These programs will need 138 to match the kernel in order to function. External programs may 139 require minor modifications to accommodate a change of type in 140 structures from pointers to 64-bit virtual addresses. 141 14220180702: 143 On i386 and amd64 atomics are now inlined. Out of tree modules using 144 atomics will need to be rebuilt. 145 14620180701: 147 The '%I' format in the kern.corefile sysctl limits the number of 148 core files that a process can generate to the number stored in the 149 debug.ncores sysctl. The '%I' format is replaced by the single digit 150 index. Previously, if all indexes were taken the kernel would overwrite 151 only a core file with the highest index in a filename. 152 Currently the system will create a new core file if there is a free 153 index or if all slots are taken it will overwrite the oldest one. 154 15520180630: 156 Clang, llvm, lld, lldb, compiler-rt and libc++ have been upgraded to 157 6.0.1. Please see the 20141231 entry below for information about 158 prerequisites and upgrading, if you are not already using clang 3.5.0 159 or higher. 160 16120180628: 162 r335753 introduced a new quoting method. However, etc/devd/devmatch.conf 163 needed to be changed to work with it. This change was made with r335763 164 and requires a mergemaster / etcupdate / etc to update the installed file. 165 16620180612: 167 r334930 changed the interface between the NFS modules, so they all 168 need to be rebuilt. r335018 did a __FreeBSD_version bump for this. 169 17020180530: 171 The kernel / userland interface for devinfo changed, so you'll 172 need a new kernel and userland as a pair for it to work (rebuilding 173 lib/libdevinfo is all that's required). devinfo and devmatch will 174 not work, but everything else will when there's a mismatch. 175 17620180523: 177 The on-disk format for hwpmc callchain records has changed to include 178 threadid corresponding to a given record. This changes the field offsets 179 and thus requires that libpmcstat be rebuilt before using a kernel 180 later than r334108. 181 18220180517: 183 The vxge(4) driver has been removed. This driver was introduced into 184 HEAD one week before the Exar left the Ethernet market and is not 185 known to be used. If you have device vxge in your kernel config file 186 it must be removed. 187 18820180510: 189 The amd64 kernel now requires a ld that supports ifunc to produce a 190 working kernel, either lld or a newer binutils. lld is built by default 191 on amd64, and the 'buildkernel' target uses it automatically. However, 192 it is not the default linker, so building the kernel the traditional 193 way requires LD=ld.lld on the command line (or LD=/usr/local/bin/ld for 194 binutils port/package). lld will soon be default, and this requirement 195 will go away. 196 19720180508: 198 The nxge(4) driver has been removed. This driver was for PCI-X 10g 199 cards made by s2io/Neterion. The company was aquired by Exar and 200 no longer sells or supports Ethernet products. If you have device 201 nxge in your kernel config file it must be removed. 202 20320180504: 204 The tz database (tzdb) has been updated to 2018e. This version more 205 correctly models time stamps in time zones with negative DST such as 206 Europe/Dublin (from 1971 on), Europe/Prague (1946/7), and 207 Africa/Windhoek (1994/2017). This does not affect the UT offsets, only 208 time zone abbreviations and the tm_isdst flag. 209 21020180502: 211 The ixgb(4) driver has been removed. This driver was for an early and 212 uncommon legacy PCI 10GbE for a single ASIC, Intel 82597EX. Intel 213 quickly shifted to the long lived ixgbe family. If you have device 214 ixgb in your kernel config file it must be removed. 215 21620180501: 217 The lmc(4) driver has been removed. This was a WAN interface 218 card that was already reportedly rare in 2003, and had an ambiguous 219 license. If you have device lmc in your kernel config file it must 220 be removed. 221 22220180413: 223 Support for Arcnet networks has been removed. If you have device 224 arcnet or device cm in your kernel config file they must be 225 removed. 226 22720180411: 228 Support for FDDI networks has been removed. If you have device 229 fddi or device fpa in your kernel config file they must be 230 removed. 231 23220180406: 233 In addition to supporting RFC 3164 formatted messages, the 234 syslogd(8) service is now capable of parsing RFC 5424 formatted 235 log messages. The main benefit of using RFC 5424 is that clients 236 may now send log messages with timestamps containing year numbers, 237 microseconds and time zone offsets. 238 239 Similarly, the syslog(3) C library function has been altered to 240 send RFC 5424 formatted messages to the local system logging 241 daemon. On systems using syslogd(8), this change should have no 242 negative impact, as long as syslogd(8) and the C library are 243 updated at the same time. On systems using a different system 244 logging daemon, it may be necessary to make configuration 245 adjustments, depending on the software used. 246 247 When using syslog-ng, add the 'syslog-protocol' flag to local 248 input sources to enable parsing of RFC 5424 formatted messages: 249 250 source src { 251 unix-dgram("/var/run/log" flags(syslog-protocol)); 252 } 253 254 When using rsyslog, disable the 'SysSock.UseSpecialParser' option 255 of the 'imuxsock' module to let messages be processed by the 256 regular RFC 3164/5424 parsing pipeline: 257 258 module(load="imuxsock" SysSock.UseSpecialParser="off") 259 260 Do note that these changes only affect communication between local 261 applications and syslogd(8). The format that syslogd(8) uses to 262 store messages on disk or forward messages to other systems 263 remains unchanged. syslogd(8) still uses RFC 3164 for these 264 purposes. Options to customize this behaviour will be added in the 265 future. Utilities that process log files stored in /var/log are 266 thus expected to continue to function as before. 267 268 __FreeBSD_version has been incremented to 1200061 to denote this 269 change. 270 27120180328: 272 Support for token ring networks has been removed. If you 273 have "device token" in your kernel config you should remove 274 it. No device drivers supported token ring. 275 27620180323: 277 makefs was modified to be able to tag ISO9660 El Torito boot catalog 278 entries as EFI instead of overloading the i386 tag as done previously. 279 The amd64 mkisoimages.sh script used to build amd64 ISO images for 280 release was updated to use this. This may mean that makefs must be 281 updated before "make cdrom" can be run in the release directory. This 282 should be as simple as: 283 284 $ cd $SRCDIR/usr.sbin/makefs 285 $ make depend all install 286 28720180212: 288 FreeBSD boot loader enhanced with Lua scripting. It's purely opt-in for 289 now by building WITH_LOADER_LUA and WITHOUT_FORTH in /etc/src.conf. 290 Co-existance for the transition period will come shortly. Booting is a 291 complex environment and test coverage for Lua-enabled loaders has been 292 thin, so it would be prudent to assume it might not work and make 293 provisions for backup boot methods. 294 29520180211: 296 devmatch functionality has been turned on in devd. It will automatically 297 load drivers for unattached devices. This may cause unexpected drivers to 298 be loaded. Please report any problems to current@ and imp@freebsd.org. 299 30020180114: 301 Clang, llvm, lld, lldb, compiler-rt and libc++ have been upgraded to 302 6.0.0. Please see the 20141231 entry below for information about 303 prerequisites and upgrading, if you are not already using clang 3.5.0 304 or higher. 305 30620180110: 307 LLVM's lld linker is now used as the FreeBSD/amd64 bootstrap linker. 308 This means it is used to link the kernel and userland libraries and 309 executables, but is not yet installed as /usr/bin/ld by default. 310 311 To revert to ld.bfd as the bootstrap linker, in /etc/src.conf set 312 WITHOUT_LLD_BOOTSTRAP=yes 313 31420180110: 315 On i386, pmtimer has been removed. Its functionality has been folded 316 into apm. It was a no-op on ACPI in current for a while now (but was still 317 needed on i386 in FreeBSD 11 and earlier). Users may need to remove it 318 from kernel config files. 319 32020180104: 321 The use of RSS hash from the network card aka flowid has been 322 disabled by default for lagg(4) as it's currently incompatible with 323 the lacp and loadbalance protocols. 324 325 This can be re-enabled by setting the following in loader.conf: 326 net.link.lagg.default_use_flowid="1" 327 32820180102: 329 The SW_WATCHDOG option is no longer necessary to enable the 330 hardclock-based software watchdog if no hardware watchdog is 331 configured. As before, SW_WATCHDOG will cause the software 332 watchdog to be enabled even if a hardware watchdog is configured. 333 33420171215: 335 r326887 fixes the issue described in the 20171214 UPDATING entry. 336 r326888 flips the switch back to building GELI support always. 337 33820171214: 339 r362593 broke ZFS + GELI support for reasons unknown. However, 340 it also broke ZFS support generally, so GELI has been turned off 341 by default as the lesser evil in r326857. If you boot off ZFS and/or 342 GELI, it might not be a good time to update. 343 34420171125: 345 PowerPC users must update loader(8) by rebuilding world before 346 installing a new kernel, as the protocol connecting them has 347 changed. Without the update, loader metadata will not be passed 348 successfully to the kernel and users will have to enter their 349 root partition at the kernel mountroot prompt to continue booting. 350 Newer versions of loader can boot old kernels without issue. 351 35220171110: 353 The LOADER_FIREWIRE_SUPPORT build variable as been renamed to 354 WITH/OUT_LOADER_FIREWIRE. LOADER_{NO_,}GELI_SUPPORT has been renamed 355 to WITH/OUT_LOADER_GELI. 356 35720171106: 358 The naive and non-compliant support of posix_fallocate(2) in ZFS 359 has been removed as of r325320. The system call now returns EINVAL 360 when used on a ZFS file. Although the new behavior complies with the 361 standard, some consumers are not prepared to cope with it. 362 One known victim is lld prior to r325420. 363 36420171102: 365 Building in a FreeBSD src checkout will automatically create object 366 directories now rather than store files in the current directory if 367 'make obj' was not ran. Calling 'make obj' is no longer necessary. 368 This feature can be disabled by setting WITHOUT_AUTO_OBJ=yes in 369 /etc/src-env.conf (not /etc/src.conf), or passing the option in the 370 environment. 371 37220171101: 373 The default MAKEOBJDIR has changed from /usr/obj/<srcdir> for native 374 builds, and /usr/obj/<arch>/<srcdir> for cross-builds, to a unified 375 /usr/obj/<srcdir>/<arch>. This behavior can be changed to the old 376 format by setting WITHOUT_UNIFIED_OBJDIR=yes in /etc/src-env.conf, 377 the environment, or with -DWITHOUT_UNIFIED_OBJDIR when building. 378 The UNIFIED_OBJDIR option is a transitional feature that will be 379 removed for 12.0 release; please migrate to the new format for any 380 tools by looking up the OBJDIR used by 'make -V .OBJDIR' means rather 381 than hardcoding paths. 382 38320171028: 384 The native-xtools target no longer installs the files by default to the 385 OBJDIR. Use the native-xtools-install target with a DESTDIR to install 386 to ${DESTDIR}/${NXTP} where NXTP defaults to /nxb-bin. 387 38820171021: 389 As part of the boot loader infrastructure cleanup, LOADER_*_SUPPORT 390 options are changing from controlling the build if defined / undefined 391 to controlling the build with explicit 'yes' or 'no' values. They will 392 shift to WITH/WITHOUT options to match other options in the system. 393 39420171010: 395 libstand has turned into a private library for sys/boot use only. 396 It is no longer supported as a public interface outside of sys/boot. 397 39820171005: 399 The arm port has split armv6 into armv6 and armv7. armv7 is now 400 a valid TARGET_ARCH/MACHINE_ARCH setting. If you have an armv7 system 401 and are running a kernel from before r324363, you will need to add 402 MACHINE_ARCH=armv7 to 'make buildworld' to do a native build. 403 40420171003: 405 When building multiple kernels using KERNCONF, non-existent KERNCONF 406 files will produce an error and buildkernel will fail. Previously 407 missing KERNCONF files silently failed giving no indication as to 408 why, only to subsequently discover during installkernel that the 409 desired kernel was never built in the first place. 410 41120170912: 412 The default serial number format for CTL LUNs has changed. This will 413 affect users who use /dev/diskid/* device nodes, or whose FibreChannel 414 or iSCSI clients care about their LUNs' serial numbers. Users who 415 require serial number stability should hardcode serial numbers in 416 /etc/ctl.conf . 417 41820170912: 419 For 32-bit arm compiled for hard-float support, soft-floating point 420 binaries now always get their shared libraries from 421 LD_SOFT_LIBRARY_PATH (in the past, this was only used if 422 /usr/libsoft also existed). Only users with a hard-float ld.so, but 423 soft-float everything else should be affected. 424 42520170826: 426 The geli password typed at boot is now hidden. To restore the previous 427 behavior, see geli(8) for configuration options. 428 42920170825: 430 Move PMTUD blackhole counters to TCPSTATS and remove them from bare 431 sysctl values. Minor nit, but requires a rebuild of both world/kernel 432 to complete. 433 43420170814: 435 "make check" behavior (made in ^/head@r295380) has been changed to 436 execute from a limited sandbox, as opposed to executing from 437 ${TESTSDIR}. 438 439 Behavioral changes: 440 - The "beforecheck" and "aftercheck" targets are now specified. 441 - ${CHECKDIR} (added in commit noted above) has been removed. 442 - Legacy behavior can be enabled by setting 443 WITHOUT_MAKE_CHECK_USE_SANDBOX in src.conf(5) or the environment. 444 445 If the limited sandbox mode is enabled, "make check" will execute 446 "make distribution", then install, execute the tests, and clean up the 447 sandbox if successful. 448 449 The "make distribution" and "make install" targets are typically run as 450 root to set appropriate permissions and ownership at installation time. 451 The end-user should set "WITH_INSTALL_AS_USER" in src.conf(5) or the 452 environment if executing "make check" with limited sandbox mode using 453 an unprivileged user. 454 45520170808: 456 Since the switch to GPT disk labels, fsck for UFS/FFS has been 457 unable to automatically find alternate superblocks. As of r322297, 458 the information needed to find alternate superblocks has been 459 moved to the end of the area reserved for the boot block. 460 Filesystems created with a newfs of this vintage or later 461 will create the recovery information. If you have a filesystem 462 created prior to this change and wish to have a recovery block 463 created for your filesystem, you can do so by running fsck in 464 foreground mode (i.e., do not use the -p or -y options). As it 465 starts, fsck will ask ``SAVE DATA TO FIND ALTERNATE SUPERBLOCKS'' 466 to which you should answer yes. 467 46820170728: 469 As of r321665, an NFSv4 server configuration that services 470 Kerberos mounts or clients that do not support the uid/gid in 471 owner/owner_group string capability, must explicitly enable 472 the nfsuserd daemon by adding nfsuserd_enable="YES" to the 473 machine's /etc/rc.conf file. 474 47520170722: 476 Clang, llvm, lldb, compiler-rt and libc++ have been upgraded to 5.0.0. 477 Please see the 20141231 entry below for information about prerequisites 478 and upgrading, if you are not already using clang 3.5.0 or higher. 479 48020170701: 481 WITHOUT_RCMDS is now the default. Set WITH_RCMDS if you need the 482 r-commands (rlogin, rsh, etc.) to be built with the base system. 483 48420170625: 485 The FreeBSD/powerpc platform now uses a 64-bit type for time_t. This is 486 a very major ABI incompatible change, so users of FreeBSD/powerpc must 487 be careful when performing source upgrades. It is best to run 488 'make installworld' from an alternate root system, either a live 489 CD/memory stick, or a temporary root partition. Additionally, all ports 490 must be recompiled. powerpc64 is largely unaffected, except in the case 491 of 32-bit compatibility. All 32-bit binaries will be affected. 492 49320170623: 494 Forward compatibility for the "ino64" project have been committed. This 495 will allow most new binaries to run on older kernels in a limited 496 fashion. This prevents many of the common foot-shooting actions in the 497 upgrade as well as the limited ability to roll back the kernel across 498 the ino64 upgrade. Complicated use cases may not work properly, though 499 enough simpler ones work to allow recovery in most situations. 500 50120170620: 502 Switch back to the BSDL dtc (Device Tree Compiler). Set WITH_GPL_DTC 503 if you require the GPL compiler. 504 50520170618: 506 The internal ABI used for communication between the NFS kernel modules 507 was changed by r320085, so __FreeBSD_version was bumped to 508 ensure all the NFS related modules are updated together. 509 51020170617: 511 The ABI of struct event was changed by extending the data 512 member to 64bit and adding ext fields. For upgrade, same 513 precautions as for the entry 20170523 "ino64" must be 514 followed. 515 51620170531: 517 The GNU roff toolchain has been removed from base. To render manpages 518 which are not supported by mandoc(1), man(1) can fallback on GNU roff 519 from ports (and recommends to install it). 520 To render roff(7) documents, consider using GNU roff from ports or the 521 heirloom doctools roff toolchain from ports via pkg install groff or 522 via pkg install heirloom-doctools. 523 52420170524: 525 The ath(4) and ath_hal(4) modules now build piecemeal to allow for 526 smaller runtime footprint builds. This is useful for embedded systems 527 which only require one chipset support. 528 529 If you load it as a module, make sure this is in /boot/loader.conf: 530 531 if_ath_load="YES" 532 533 This will load the HAL, all chip/RF backends and if_ath_pci. 534 If you have if_ath_pci in /boot/loader.conf, ensure it is after 535 if_ath or it will not load any HAL chipset support. 536 537 If you want to selectively load things (eg on ye cheape ARM/MIPS 538 platforms where RAM is at a premium) you should: 539 540 * load ath_hal 541 * load the chip modules in question 542 * load ath_rate, ath_dfs 543 * load ath_main 544 * load if_ath_pci and/or if_ath_ahb depending upon your particular 545 bus bind type - this is where probe/attach is done. 546 547 For further comments/feedback, poke adrian@ . 548 54920170523: 550 The "ino64" 64-bit inode project has been committed, which extends 551 a number of types to 64 bits. Upgrading in place requires care and 552 adherence to the documented upgrade procedure. 553 554 If using a custom kernel configuration ensure that the 555 COMPAT_FREEBSD11 option is included (as during the upgrade the 556 system will be running the ino64 kernel with the existing world). 557 558 For the safest in-place upgrade begin by removing previous build 559 artifacts via "rm -rf /usr/obj/*". Then, carefully follow the 560 full procedure documented below under the heading "To rebuild 561 everything and install it on the current system." Specifically, 562 a reboot is required after installing the new kernel before 563 installing world. 564 56520170424: 566 The NATM framework including the en(4), fatm(4), hatm(4), and 567 patm(4) devices has been removed. Consumers should plan a 568 migration before the end-of-life date for FreeBSD 11. 569 57020170420: 571 GNU diff has been replaced by a BSD licensed diff. Some features of GNU 572 diff has not been implemented, if those are needed a newer version of 573 GNU diff is available via the diffutils package under the gdiff name. 574 57520170413: 576 As of r316810 for ipfilter, keep frags is no longer assumed when 577 keep state is specified in a rule. r316810 aligns ipfilter with 578 documentation in man pages separating keep frags from keep state. 579 This allows keep state to be specified without forcing keep frags 580 and allows keep frags to be specified independently of keep state. 581 To maintain previous behaviour, also specify keep frags with 582 keep state (as documented in ipf.conf.5). 583 58420170407: 585 arm64 builds now use the base system LLD 4.0.0 linker by default, 586 instead of requiring that the aarch64-binutils port or package be 587 installed. To continue using aarch64-binutils, set 588 CROSS_BINUTILS_PREFIX=/usr/local/aarch64-freebsd/bin . 589 59020170405: 591 The UDP optimization in entry 20160818 that added the sysctl 592 net.inet.udp.require_l2_bcast has been reverted. L2 broadcast 593 packets will no longer be treated as L3 broadcast packets. 594 59520170331: 596 Binds and sends to the loopback addresses, IPv6 and IPv4, will now 597 use any explicitly assigned loopback address available in the jail 598 instead of using the first assigned address of the jail. 599 60020170329: 601 The ctl.ko module no longer implements the iSCSI target frontend: 602 cfiscsi.ko does instead. 603 604 If building cfiscsi.ko as a kernel module, the module can be loaded 605 via one of the following methods: 606 - `cfiscsi_load="YES"` in loader.conf(5). 607 - Add `cfiscsi` to `$kld_list` in rc.conf(5). 608 - ctladm(8)/ctld(8), when compiled with iSCSI support 609 (`WITH_ISCSI=yes` in src.conf(5)) 610 611 Please see cfiscsi(4) for more details. 612 61320170316: 614 The mmcsd.ko module now additionally depends on geom_flashmap.ko. 615 Also, mmc.ko and mmcsd.ko need to be a matching pair built from the 616 same source (previously, the dependency of mmcsd.ko on mmc.ko was 617 missing, but mmcsd.ko now will refuse to load if it is incompatible 618 with mmc.ko). 619 62020170315: 621 The syntax of ipfw(8) named states was changed to avoid ambiguity. 622 If you have used named states in the firewall rules, you need to modify 623 them after installworld and before rebooting. Now named states must 624 be prefixed with colon. 625 62620170311: 627 The old drm (sys/dev/drm/) drivers for i915 and radeon have been 628 removed as the userland we provide cannot use them. The KMS version 629 (sys/dev/drm2) supports the same hardware. 630 63120170302: 632 Clang, llvm, lldb, compiler-rt and libc++ have been upgraded to 4.0.0. 633 Please see the 20141231 entry below for information about prerequisites 634 and upgrading, if you are not already using clang 3.5.0 or higher. 635 63620170221: 637 The code that provides support for ZFS .zfs/ directory functionality 638 has been reimplemented. It's not possible now to create a snapshot 639 by mkdir under .zfs/snapshot/. That should be the only user visible 640 change. 641 64220170216: 643 EISA bus support has been removed. The WITH_EISA option is no longer 644 valid. 645 64620170215: 647 MCA bus support has been removed. 648 64920170127: 650 The WITH_LLD_AS_LD / WITHOUT_LLD_AS_LD build knobs have been renamed 651 WITH_LLD_IS_LD / WITHOUT_LLD_IS_LD, for consistency with CLANG_IS_CC. 652 65320170112: 654 The EM_MULTIQUEUE kernel configuration option is deprecated now that 655 the em(4) driver conforms to iflib specifications. 656 65720170109: 658 The igb(4), em(4) and lem(4) ethernet drivers are now implemented via 659 IFLIB. If you have a custom kernel configuration that excludes em(4) 660 but you use igb(4), you need to re-add em(4) to your custom configuration. 661 66220161217: 663 Clang, llvm, lldb, compiler-rt and libc++ have been upgraded to 3.9.1. 664 Please see the 20141231 entry below for information about prerequisites 665 and upgrading, if you are not already using clang 3.5.0 or higher. 666 66720161124: 668 Clang, llvm, lldb, compiler-rt and libc++ have been upgraded to 3.9.0. 669 Please see the 20141231 entry below for information about prerequisites 670 and upgrading, if you are not already using clang 3.5.0 or higher. 671 67220161119: 673 The layout of the pmap structure has changed for powerpc to put the pmap 674 statistics at the front for all CPU variations. libkvm(3) and all tools 675 that link against it need to be recompiled. 676 67720161030: 678 isl(4) and cyapa(4) drivers now require a new driver, 679 chromebook_platform(4), to work properly on Chromebook-class hardware. 680 On other types of hardware the drivers may need to be configured using 681 device hints. Please see the corresponding manual pages for details. 682 68320161017: 684 The urtwn(4) driver was merged into rtwn(4) and now consists of 685 rtwn(4) main module + rtwn_usb(4) and rtwn_pci(4) bus-specific 686 parts. 687 Also, firmware for RTL8188CE was renamed due to possible name 688 conflict (rtwnrtl8192cU(B) -> rtwnrtl8192cE(B)) 689 69020161015: 691 GNU rcs has been removed from base. It is available as packages: 692 - rcs: Latest GPLv3 GNU rcs version. 693 - rcs57: Copy of the latest version of GNU rcs (GPLv2) before it was 694 removed from base. 695 69620161008: 697 Use of the cc_cdg, cc_chd, cc_hd, or cc_vegas congestion control 698 modules now requires that the kernel configuration contain the 699 TCP_HHOOK option. (This option is included in the GENERIC kernel.) 700 70120161003: 702 The WITHOUT_ELFCOPY_AS_OBJCOPY src.conf(5) knob has been retired. 703 ELF Tool Chain's elfcopy is always installed as /usr/bin/objcopy. 704 70520160924: 706 Relocatable object files with the extension of .So have been renamed 707 to use an extension of .pico instead. The purpose of this change is 708 to avoid a name clash with shared libraries on case-insensitive file 709 systems. On those file systems, foo.So is the same file as foo.so. 710 71120160918: 712 GNU rcs has been turned off by default. It can (temporarily) be built 713 again by adding WITH_RCS knob in src.conf. 714 Otherwise, GNU rcs is available from packages: 715 - rcs: Latest GPLv3 GNU rcs version. 716 - rcs57: Copy of the latest version of GNU rcs (GPLv2) from base. 717 71820160918: 719 The backup_uses_rcs functionality has been removed from rc.subr. 720 72120160908: 722 The queue(3) debugging macro, QUEUE_MACRO_DEBUG, has been split into 723 two separate components, QUEUE_MACRO_DEBUG_TRACE and 724 QUEUE_MACRO_DEBUG_TRASH. Define both for the original 725 QUEUE_MACRO_DEBUG behavior. 726 72720160824: 728 r304787 changed some ioctl interfaces between the iSCSI userspace 729 programs and the kernel. ctladm, ctld, iscsictl, and iscsid must be 730 rebuilt to work with new kernels. __FreeBSD_version has been bumped 731 to 1200005. 732 73320160818: 734 The UDP receive code has been updated to only treat incoming UDP 735 packets that were addressed to an L2 broadcast address as L3 736 broadcast packets. It is not expected that this will affect any 737 standards-conforming UDP application. The new behaviour can be 738 disabled by setting the sysctl net.inet.udp.require_l2_bcast to 739 0. 740 74120160818: 742 Remove the openbsd_poll system call. 743 __FreeBSD_version has been bumped because of this. 744 74520160708: 746 The stable/11 branch has been created from head@r302406. 747 74820160622: 749 The libc stub for the pipe(2) system call has been replaced with 750 a wrapper that calls the pipe2(2) system call and the pipe(2) 751 system call is now only implemented by the kernels that include 752 "options COMPAT_FREEBSD10" in their config file (this is the 753 default). Users should ensure that this option is enabled in 754 their kernel or upgrade userspace to r302092 before upgrading their 755 kernel. 756 75720160527: 758 CAM will now strip leading spaces from SCSI disks' serial numbers. 759 This will affect users who create UFS filesystems on SCSI disks using 760 those disk's diskid device nodes. For example, if /etc/fstab 761 previously contained a line like 762 "/dev/diskid/DISK-%20%20%20%20%20%20%20ABCDEFG0123456", you should 763 change it to "/dev/diskid/DISK-ABCDEFG0123456". Users of geom 764 transforms like gmirror may also be affected. ZFS users should 765 generally be fine. 766 76720160523: 768 The bitstring(3) API has been updated with new functionality and 769 improved performance. But it is binary-incompatible with the old API. 770 Objects built with the new headers may not be linked against objects 771 built with the old headers. 772 77320160520: 774 The brk and sbrk functions have been removed from libc on arm64. 775 Binutils from ports has been updated to not link to these 776 functions and should be updated to the latest version before 777 installing a new libc. 778 77920160517: 780 The armv6 port now defaults to hard float ABI. Limited support 781 for running both hardfloat and soft float on the same system 782 is available using the libraries installed with -DWITH_LIBSOFT. 783 This has only been tested as an upgrade path for installworld 784 and packages may fail or need manual intervention to run. New 785 packages will be needed. 786 787 To update an existing self-hosted armv6hf system, you must add 788 TARGET_ARCH=armv6 on the make command line for both the build 789 and the install steps. 790 79120160510: 792 Kernel modules compiled outside of a kernel build now default to 793 installing to /boot/modules instead of /boot/kernel. Many kernel 794 modules built this way (such as those in ports) already overrode 795 KMODDIR explicitly to install into /boot/modules. However, 796 manually building and installing a module from /sys/modules will 797 now install to /boot/modules instead of /boot/kernel. 798 79920160414: 800 The CAM I/O scheduler has been committed to the kernel. There should be 801 no user visible impact. This does enable NCQ Trim on ada SSDs. While the 802 list of known rogues that claim support for this but actually corrupt 803 data is believed to be complete, be on the lookout for data 804 corruption. The known rogue list is believed to be complete: 805 806 o Crucial MX100, M550 drives with MU01 firmware. 807 o Micron M510 and M550 drives with MU01 firmware. 808 o Micron M500 prior to MU07 firmware 809 o Samsung 830, 840, and 850 all firmwares 810 o FCCT M500 all firmwares 811 812 Crucial has firmware http://www.crucial.com/usa/en/support-ssd-firmware 813 with working NCQ TRIM. For Micron branded drives, see your sales rep for 814 updated firmware. Black listed drives will work correctly because these 815 drives work correctly so long as no NCQ TRIMs are sent to them. Given 816 this list is the same as found in Linux, it's believed there are no 817 other rogues in the market place. All other models from the above 818 vendors work. 819 820 To be safe, if you are at all concerned, you can quirk each of your 821 drives to prevent NCQ from being sent by setting: 822 kern.cam.ada.X.quirks="0x2" 823 in loader.conf. If the drive requires the 4k sector quirk, set the 824 quirks entry to 0x3. 825 82620160330: 827 The FAST_DEPEND build option has been removed and its functionality is 828 now the one true way. The old mkdep(1) style of 'make depend' has 829 been removed. See 20160311 for further details. 830 83120160317: 832 Resource range types have grown from unsigned long to uintmax_t. All 833 drivers, and anything using libdevinfo, need to be recompiled. 834 83520160311: 836 WITH_FAST_DEPEND is now enabled by default for in-tree and out-of-tree 837 builds. It no longer runs mkdep(1) during 'make depend', and the 838 'make depend' stage can safely be skipped now as it is auto ran 839 when building 'make all' and will generate all SRCS and DPSRCS before 840 building anything else. Dependencies are gathered at compile time with 841 -MF flags kept in separate .depend files per object file. Users should 842 run 'make cleandepend' once if using -DNO_CLEAN to clean out older 843 stale .depend files. 844 84520160306: 846 On amd64, clang 3.8.0 can now insert sections of type AMD64_UNWIND into 847 kernel modules. Therefore, if you load any kernel modules at boot time, 848 please install the boot loaders after you install the kernel, but before 849 rebooting, e.g.: 850 851 make buildworld 852 make buildkernel KERNCONF=YOUR_KERNEL_HERE 853 make installkernel KERNCONF=YOUR_KERNEL_HERE 854 make -C sys/boot install 855 <reboot in single user> 856 857 Then follow the usual steps, described in the General Notes section, 858 below. 859 86020160305: 861 Clang, llvm, lldb and compiler-rt have been upgraded to 3.8.0. Please 862 see the 20141231 entry below for information about prerequisites and 863 upgrading, if you are not already using clang 3.5.0 or higher. 864 86520160301: 866 The AIO subsystem is now a standard part of the kernel. The 867 VFS_AIO kernel option and aio.ko kernel module have been removed. 868 Due to stability concerns, asynchronous I/O requests are only 869 permitted on sockets and raw disks by default. To enable 870 asynchronous I/O requests on all file types, set the 871 vfs.aio.enable_unsafe sysctl to a non-zero value. 872 87320160226: 874 The ELF object manipulation tool objcopy is now provided by the 875 ELF Tool Chain project rather than by GNU binutils. It should be a 876 drop-in replacement, with the addition of arm64 support. The 877 (temporary) src.conf knob WITHOUT_ELFCOPY_AS_OBJCOPY knob may be set 878 to obtain the GNU version if necessary. 879 88020160129: 881 Building ZFS pools on top of zvols is prohibited by default. That 882 feature has never worked safely; it's always been prone to deadlocks. 883 Using a zvol as the backing store for a VM guest's virtual disk will 884 still work, even if the guest is using ZFS. Legacy behavior can be 885 restored by setting vfs.zfs.vol.recursive=1. 886 88720160119: 888 The NONE and HPN patches has been removed from OpenSSH. They are 889 still available in the security/openssh-portable port. 890 89120160113: 892 With the addition of ypldap(8), a new _ypldap user is now required 893 during installworld. "mergemaster -p" can be used to add the user 894 prior to installworld, as documented in the handbook. 895 89620151216: 897 The tftp loader (pxeboot) now uses the option root-path directive. As a 898 consequence it no longer looks for a pxeboot.4th file on the tftp 899 server. Instead it uses the regular /boot infrastructure as with the 900 other loaders. 901 90220151211: 903 The code to start recording plug and play data into the modules has 904 been committed. While the old tools will properly build a new kernel, 905 a number of warnings about "unknown metadata record 4" will be produced 906 for an older kldxref. To avoid such warnings, make sure to rebuild 907 the kernel toolchain (or world). Make sure that you have r292078 or 908 later when trying to build 292077 or later before rebuilding. 909 91020151207: 911 Debug data files are now built by default with 'make buildworld' and 912 installed with 'make installworld'. This facilitates debugging but 913 requires more disk space both during the build and for the installed 914 world. Debug files may be disabled by setting WITHOUT_DEBUG_FILES=yes 915 in src.conf(5). 916 91720151130: 918 r291527 changed the internal interface between the nfsd.ko and 919 nfscommon.ko modules. As such, they must both be upgraded to-gether. 920 __FreeBSD_version has been bumped because of this. 921 92220151108: 923 Add support for unicode collation strings leads to a change of 924 order of files listed by ls(1) for example. To get back to the old 925 behaviour, set LC_COLLATE environment variable to "C". 926 927 Databases administrators will need to reindex their databases given 928 collation results will be different. 929 930 Due to a bug in install(1) it is recommended to remove the ancient 931 locales before running make installworld. 932 933 rm -rf /usr/share/locale/* 934 93520151030: 936 The OpenSSL has been upgraded to 1.0.2d. Any binaries requiring 937 libcrypto.so.7 or libssl.so.7 must be recompiled. 938 93920151020: 940 Qlogic 24xx/25xx firmware images were updated from 5.5.0 to 7.3.0. 941 Kernel modules isp_2400_multi and isp_2500_multi were removed and 942 should be replaced with isp_2400 and isp_2500 modules respectively. 943 94420151017: 945 The build previously allowed using 'make -n' to not recurse into 946 sub-directories while showing what commands would be executed, and 947 'make -n -n' to recursively show commands. Now 'make -n' will recurse 948 and 'make -N' will not. 949 95020151012: 951 If you specify SENDMAIL_MC or SENDMAIL_CF in make.conf, mergemaster 952 and etcupdate will now use this file. A custom sendmail.cf is now 953 updated via this mechanism rather than via installworld. If you had 954 excluded sendmail.cf in mergemaster.rc or etcupdate.conf, you may 955 want to remove the exclusion or change it to "always install". 956 /etc/mail/sendmail.cf is now managed the same way regardless of 957 whether SENDMAIL_MC/SENDMAIL_CF is used. If you are not using 958 SENDMAIL_MC/SENDMAIL_CF there should be no change in behavior. 959 96020151011: 961 Compatibility shims for legacy ATA device names have been removed. 962 It includes ATA_STATIC_ID kernel option, kern.cam.ada.legacy_aliases 963 and kern.geom.raid.legacy_aliases loader tunables, kern.devalias.* 964 environment variables, /dev/ad* and /dev/ar* symbolic links. 965 96620151006: 967 Clang, llvm, lldb, compiler-rt and libc++ have been upgraded to 3.7.0. 968 Please see the 20141231 entry below for information about prerequisites 969 and upgrading, if you are not already using clang 3.5.0 or higher. 970 97120150924: 972 Kernel debug files have been moved to /usr/lib/debug/boot/kernel/, 973 and renamed from .symbols to .debug. This reduces the size requirements 974 on the boot partition or file system and provides consistency with 975 userland debug files. 976 977 When using the supported kernel installation method the 978 /usr/lib/debug/boot/kernel directory will be renamed (to kernel.old) 979 as is done with /boot/kernel. 980 981 Developers wishing to maintain the historical behavior of installing 982 debug files in /boot/kernel/ can set KERN_DEBUGDIR="" in src.conf(5). 983 98420150827: 985 The wireless drivers had undergone changes that remove the 'parent 986 interface' from the ifconfig -l output. The rc.d network scripts 987 used to check presence of a parent interface in the list, so old 988 scripts would fail to start wireless networking. Thus, etcupdate(3) 989 or mergemaster(8) run is required after kernel update, to update your 990 rc.d scripts in /etc. 991 99220150827: 993 pf no longer supports 'scrub fragment crop' or 'scrub fragment drop-ovl' 994 These configurations are now automatically interpreted as 995 'scrub fragment reassemble'. 996 99720150817: 998 Kernel-loadable modules for the random(4) device are back. To use 999 them, the kernel must have 1000 1001 device random 1002 options RANDOM_LOADABLE 1003 1004 kldload(8) can then be used to load random_fortuna.ko 1005 or random_yarrow.ko. Please note that due to the indirect 1006 function calls that the loadable modules need to provide, 1007 the build-in variants will be slightly more efficient. 1008 1009 The random(4) kernel option RANDOM_DUMMY has been retired due to 1010 unpopularity. It was not all that useful anyway. 1011 101220150813: 1013 The WITHOUT_ELFTOOLCHAIN_TOOLS src.conf(5) knob has been retired. 1014 Control over building the ELF Tool Chain tools is now provided by 1015 the WITHOUT_TOOLCHAIN knob. 1016 101720150810: 1018 The polarity of Pulse Per Second (PPS) capture events with the 1019 uart(4) driver has been corrected. Prior to this change the PPS 1020 "assert" event corresponded to the trailing edge of a positive PPS 1021 pulse and the "clear" event was the leading edge of the next pulse. 1022 1023 As the width of a PPS pulse in a typical GPS receiver is on the 1024 order of 1 millisecond, most users will not notice any significant 1025 difference with this change. 1026 1027 Anyone who has compensated for the historical polarity reversal by 1028 configuring a negative offset equal to the pulse width will need to 1029 remove that workaround. 1030 103120150809: 1032 The default group assigned to /dev/dri entries has been changed 1033 from 'wheel' to 'video' with the id of '44'. If you want to have 1034 access to the dri devices please add yourself to the video group 1035 with: 1036 1037 # pw groupmod video -m $USER 1038 103920150806: 1040 The menu.rc and loader.rc files will now be replaced during 1041 upgrades. Please migrate local changes to menu.rc.local and 1042 loader.rc.local instead. 1043 104420150805: 1045 GNU Binutils versions of addr2line, c++filt, nm, readelf, size, 1046 strings and strip have been removed. The src.conf(5) knob 1047 WITHOUT_ELFTOOLCHAIN_TOOLS no longer provides the binutils tools. 1048 104920150728: 1050 As ZFS requires more kernel stack pages than is the default on some 1051 architectures e.g. i386, it now warns if KSTACK_PAGES is less than 1052 ZFS_MIN_KSTACK_PAGES (which is 4 at the time of writing). 1053 1054 Please consider using 'options KSTACK_PAGES=X' where X is greater 1055 than or equal to ZFS_MIN_KSTACK_PAGES i.e. 4 in such configurations. 1056 105720150706: 1058 sendmail has been updated to 8.15.2. Starting with FreeBSD 11.0 1059 and sendmail 8.15, sendmail uses uncompressed IPv6 addresses by 1060 default, i.e., they will not contain "::". For example, instead 1061 of ::1, it will be 0:0:0:0:0:0:0:1. This permits a zero subnet 1062 to have a more specific match, such as different map entries for 1063 IPv6:0:0 vs IPv6:0. This change requires that configuration 1064 data (including maps, files, classes, custom ruleset, etc.) must 1065 use the same format, so make certain such configuration data is 1066 upgrading. As a very simple check search for patterns like 1067 'IPv6:[0-9a-fA-F:]*::' and 'IPv6::'. To return to the old 1068 behavior, set the m4 option confUSE_COMPRESSED_IPV6_ADDRESSES or 1069 the cf option UseCompressedIPv6Addresses. 1070 107120150630: 1072 The default kernel entropy-processing algorithm is now 1073 Fortuna, replacing Yarrow. 1074 1075 Assuming you have 'device random' in your kernel config 1076 file, the configurations allow a kernel option to override 1077 this default. You may choose *ONE* of: 1078 1079 options RANDOM_YARROW # Legacy /dev/random algorithm. 1080 options RANDOM_DUMMY # Blocking-only driver. 1081 1082 If you have neither, you get Fortuna. For most people, 1083 read no further, Fortuna will give a /dev/random that works 1084 like it always used to, and the difference will be irrelevant. 1085 1086 If you remove 'device random', you get *NO* kernel-processed 1087 entropy at all. This may be acceptable to folks building 1088 embedded systems, but has complications. Carry on reading, 1089 and it is assumed you know what you need. 1090 1091 *PLEASE* read random(4) and random(9) if you are in the 1092 habit of tweaking kernel configs, and/or if you are a member 1093 of the embedded community, wanting specific and not-usual 1094 behaviour from your security subsystems. 1095 1096 NOTE!! If you use RANDOM_DUMMY and/or have no 'device 1097 random', you will NOT have a functioning /dev/random, and 1098 many cryptographic features will not work, including SSH. 1099 You may also find strange behaviour from the random(3) set 1100 of library functions, in particular sranddev(3), srandomdev(3) 1101 and arc4random(3). The reason for this is that the KERN_ARND 1102 sysctl only returns entropy if it thinks it has some to 1103 share, and with RANDOM_DUMMY or no 'device random' this 1104 will never happen. 1105 110620150623: 1107 An additional fix for the issue described in the 20150614 sendmail 1108 entry below has been committed in revision 284717. 1109 111020150616: 1111 FreeBSD's old make (fmake) has been removed from the system. It is 1112 available as the devel/fmake port or via pkg install fmake. 1113 111420150615: 1115 The fix for the issue described in the 20150614 sendmail entry 1116 below has been committed in revision 284436. The work 1117 around described in that entry is no longer needed unless the 1118 default setting is overridden by a confDH_PARAMETERS configuration 1119 setting of '5' or pointing to a 512 bit DH parameter file. 1120 112120150614: 1122 ALLOW_DEPRECATED_ATF_TOOLS/ATFFILE support has been removed from 1123 atf.test.mk (included from bsd.test.mk). Please upgrade devel/atf 1124 and devel/kyua to version 0.20+ and adjust any calling code to work 1125 with Kyuafile and kyua. 1126 112720150614: 1128 The import of openssl to address the FreeBSD-SA-15:10.openssl 1129 security advisory includes a change which rejects handshakes 1130 with DH parameters below 768 bits. sendmail releases prior 1131 to 8.15.2 (not yet released), defaulted to a 512 bit 1132 DH parameter setting for client connections. To work around 1133 this interoperability, sendmail can be configured to use a 1134 2048 bit DH parameter by: 1135 1136 1. Edit /etc/mail/`hostname`.mc 1137 2. If a setting for confDH_PARAMETERS does not exist or 1138 exists and is set to a string beginning with '5', 1139 replace it with '2'. 1140 3. If a setting for confDH_PARAMETERS exists and is set to 1141 a file path, create a new file with: 1142 openssl dhparam -out /path/to/file 2048 1143 4. Rebuild the .cf file: 1144 cd /etc/mail/; make; make install 1145 5. Restart sendmail: 1146 cd /etc/mail/; make restart 1147 1148 A sendmail patch is coming, at which time this file will be 1149 updated. 1150 115120150604: 1152 Generation of legacy formatted entries have been disabled by default 1153 in pwd_mkdb(8), as all base system consumers of the legacy formatted 1154 entries were converted to use the new format by default when the new, 1155 machine independent format have been added and supported since FreeBSD 1156 5.x. 1157 1158 Please see the pwd_mkdb(8) manual page for further details. 1159 116020150525: 1161 Clang and llvm have been upgraded to 3.6.1 release. Please see the 1162 20141231 entry below for information about prerequisites and upgrading, 1163 if you are not already using 3.5.0 or higher. 1164 116520150521: 1166 TI platform code switched to using vendor DTS files and this update 1167 may break existing systems running on Beaglebone, Beaglebone Black, 1168 and Pandaboard: 1169 1170 - dtb files should be regenerated/reinstalled. Filenames are the 1171 same but content is different now 1172 - GPIO addressing was changed, now each GPIO bank (32 pins per bank) 1173 has its own /dev/gpiocX device, e.g. pin 121 on /dev/gpioc0 in old 1174 addressing scheme is now pin 25 on /dev/gpioc3. 1175 - Pandaboard: /etc/ttys should be updated, serial console device is 1176 now /dev/ttyu2, not /dev/ttyu0 1177 117820150501: 1179 soelim(1) from gnu/usr.bin/groff has been replaced by usr.bin/soelim. 1180 If you need the GNU extension from groff soelim(1), install groff 1181 from package: pkg install groff, or via ports: textproc/groff. 1182 118320150423: 1184 chmod, chflags, chown and chgrp now affect symlinks in -R mode as 1185 defined in symlink(7); previously symlinks were silently ignored. 1186 118720150415: 1188 The const qualifier has been removed from iconv(3) to comply with 1189 POSIX. The ports tree is aware of this from r384038 onwards. 1190 119120150416: 1192 Libraries specified by LIBADD in Makefiles must have a corresponding 1193 DPADD_<lib> variable to ensure correct dependencies. This is now 1194 enforced in src.libnames.mk. 1195 119620150324: 1197 From legacy ata(4) driver was removed support for SATA controllers 1198 supported by more functional drivers ahci(4), siis(4) and mvs(4). 1199 Kernel modules ataahci and ataadaptec were removed completely, 1200 replaced by ahci and mvs modules respectively. 1201 120220150315: 1203 Clang, llvm and lldb have been upgraded to 3.6.0 release. Please see 1204 the 20141231 entry below for information about prerequisites and 1205 upgrading, if you are not already using 3.5.0 or higher. 1206 120720150307: 1208 The 32-bit PowerPC kernel has been changed to a position-independent 1209 executable. This can only be booted with a version of loader(8) 1210 newer than January 31, 2015, so make sure to update both world and 1211 kernel before rebooting. 1212 121320150217: 1214 If you are running a -CURRENT kernel since r273872 (Oct 30th, 2014), 1215 but before r278950, the RNG was not seeded properly. Immediately 1216 upgrade the kernel to r278950 or later and regenerate any keys (e.g. 1217 ssh keys or openssl keys) that were generated w/ a kernel from that 1218 range. This does not affect programs that directly used /dev/random 1219 or /dev/urandom. All userland uses of arc4random(3) are affected. 1220 122120150210: 1222 The autofs(4) ABI was changed in order to restore binary compatibility 1223 with 10.1-RELEASE. The automountd(8) daemon needs to be rebuilt to work 1224 with the new kernel. 1225 122620150131: 1227 The powerpc64 kernel has been changed to a position-independent 1228 executable. This can only be booted with a new version of loader(8), 1229 so make sure to update both world and kernel before rebooting. 1230 123120150118: 1232 Clang and llvm have been upgraded to 3.5.1 release. This is a bugfix 1233 only release, no new features have been added. Please see the 20141231 1234 entry below for information about prerequisites and upgrading, if you 1235 are not already using 3.5.0. 1236 123720150107: 1238 ELF tools addr2line, elfcopy (strip), nm, size, and strings are now 1239 taken from the ELF Tool Chain project rather than GNU binutils. They 1240 should be drop-in replacements, with the addition of arm64 support. 1241 The WITHOUT_ELFTOOLCHAIN_TOOLS= knob may be used to obtain the 1242 binutils tools, if necessary. See 20150805 for updated information. 1243 124420150105: 1245 The default Unbound configuration now enables remote control 1246 using a local socket. Users who have already enabled the 1247 local_unbound service should regenerate their configuration 1248 by running "service local_unbound setup" as root. 1249 125020150102: 1251 The GNU texinfo and GNU info pages have been removed. 1252 To be able to view GNU info pages please install texinfo from ports. 1253 125420141231: 1255 Clang, llvm and lldb have been upgraded to 3.5.0 release. 1256 1257 As of this release, a prerequisite for building clang, llvm and lldb is 1258 a C++11 capable compiler and C++11 standard library. This means that to 1259 be able to successfully build the cross-tools stage of buildworld, with 1260 clang as the bootstrap compiler, your system compiler or cross compiler 1261 should either be clang 3.3 or later, or gcc 4.8 or later, and your 1262 system C++ library should be libc++, or libdstdc++ from gcc 4.8 or 1263 later. 1264 1265 On any standard FreeBSD 10.x or 11.x installation, where clang and 1266 libc++ are on by default (that is, on x86 or arm), this should work out 1267 of the box. 1268 1269 On 9.x installations where clang is enabled by default, e.g. on x86 and 1270 powerpc, libc++ will not be enabled by default, so libc++ should be 1271 built (with clang) and installed first. If both clang and libc++ are 1272 missing, build clang first, then use it to build libc++. 1273 1274 On 8.x and earlier installations, upgrade to 9.x first, and then follow 1275 the instructions for 9.x above. 1276 1277 Sparc64 and mips users are unaffected, as they still use gcc 4.2.1 by 1278 default, and do not build clang. 1279 1280 Many embedded systems are resource constrained, and will not be able to 1281 build clang in a reasonable time, or in some cases at all. In those 1282 cases, cross building bootable systems on amd64 is a workaround. 1283 1284 This new version of clang introduces a number of new warnings, of which 1285 the following are most likely to appear: 1286 1287 -Wabsolute-value 1288 1289 This warns in two cases, for both C and C++: 1290 * When the code is trying to take the absolute value of an unsigned 1291 quantity, which is effectively a no-op, and almost never what was 1292 intended. The code should be fixed, if at all possible. If you are 1293 sure that the unsigned quantity can be safely cast to signed, without 1294 loss of information or undefined behavior, you can add an explicit 1295 cast, or disable the warning. 1296 1297 * When the code is trying to take an absolute value, but the called 1298 abs() variant is for the wrong type, which can lead to truncation. 1299 If you want to disable the warning instead of fixing the code, please 1300 make sure that truncation will not occur, or it might lead to unwanted 1301 side-effects. 1302 1303 -Wtautological-undefined-compare and 1304 -Wundefined-bool-conversion 1305 1306 These warn when C++ code is trying to compare 'this' against NULL, while 1307 'this' should never be NULL in well-defined C++ code. However, there is 1308 some legacy (pre C++11) code out there, which actively abuses this 1309 feature, which was less strictly defined in previous C++ versions. 1310 1311 Squid and openjdk do this, for example. The warning can be turned off 1312 for C++98 and earlier, but compiling the code in C++11 mode might result 1313 in unexpected behavior; for example, the parts of the program that are 1314 unreachable could be optimized away. 1315 131620141222: 1317 The old NFS client and server (kernel options NFSCLIENT, NFSSERVER) 1318 kernel sources have been removed. The .h files remain, since some 1319 utilities include them. This will need to be fixed later. 1320 If "mount -t oldnfs ..." is attempted, it will fail. 1321 If the "-o" option on mountd(8), nfsd(8) or nfsstat(1) is used, 1322 the utilities will report errors. 1323 132420141121: 1325 The handling of LOCAL_LIB_DIRS has been altered to skip addition of 1326 directories to top level SUBDIR variable when their parent 1327 directory is included in LOCAL_DIRS. Users with build systems with 1328 such hierarchies and without SUBDIR entries in the parent 1329 directory Makefiles should add them or add the directories to 1330 LOCAL_DIRS. 1331 133220141109: 1333 faith(4) and faithd(8) have been removed from the base system. Faith 1334 has been obsolete for a very long time. 1335 133620141104: 1337 vt(4), the new console driver, is enabled by default. It brings 1338 support for Unicode and double-width characters, as well as 1339 support for UEFI and integration with the KMS kernel video 1340 drivers. 1341 1342 You may need to update your console settings in /etc/rc.conf, 1343 most probably the keymap. During boot, /etc/rc.d/syscons will 1344 indicate what you need to do. 1345 1346 vt(4) still has issues and lacks some features compared to 1347 syscons(4). See the wiki for up-to-date information: 1348 https://wiki.freebsd.org/Newcons 1349 1350 If you want to keep using syscons(4), you can do so by adding 1351 the following line to /boot/loader.conf: 1352 kern.vty=sc 1353 135420141102: 1355 pjdfstest has been integrated into kyua as an opt-in test suite. 1356 Please see share/doc/pjdfstest/README for more details on how to 1357 execute it. 1358 135920141009: 1360 gperf has been removed from the base system for architectures 1361 that use clang. Ports that require gperf will obtain it from the 1362 devel/gperf port. 1363 136420140923: 1365 pjdfstest has been moved from tools/regression/pjdfstest to 1366 contrib/pjdfstest . 1367 136820140922: 1369 At svn r271982, The default linux compat kernel ABI has been adjusted 1370 to 2.6.18 in support of the linux-c6 compat ports infrastructure 1371 update. If you wish to continue using the linux-f10 compat ports, 1372 add compat.linux.osrelease=2.6.16 to your local sysctl.conf. Users are 1373 encouraged to update their linux-compat packages to linux-c6 during 1374 their next update cycle. 1375 137620140729: 1377 The ofwfb driver, used to provide a graphics console on PowerPC when 1378 using vt(4), no longer allows mmap() of all physical memory. This 1379 will prevent Xorg on PowerPC with some ATI graphics cards from 1380 initializing properly unless x11-servers/xorg-server is updated to 1381 1.12.4_8 or newer. 1382 138320140723: 1384 The xdev targets have been converted to using TARGET and 1385 TARGET_ARCH instead of XDEV and XDEV_ARCH. 1386 138720140719: 1388 The default unbound configuration has been modified to address 1389 issues with reverse lookups on networks that use private 1390 address ranges. If you use the local_unbound service, run 1391 "service local_unbound setup" as root to regenerate your 1392 configuration, then "service local_unbound reload" to load the 1393 new configuration. 1394 139520140709: 1396 The GNU texinfo and GNU info pages are not built and installed 1397 anymore, WITH_INFO knob has been added to allow to built and install 1398 them again. 1399 UPDATE: see 20150102 entry on texinfo's removal 1400 140120140708: 1402 The GNU readline library is now an INTERNALLIB - that is, it is 1403 statically linked into consumers (GDB and variants) in the base 1404 system, and the shared library is no longer installed. The 1405 devel/readline port is available for third party software that 1406 requires readline. 1407 140820140702: 1409 The Itanium architecture (ia64) has been removed from the list of 1410 known architectures. This is the first step in the removal of the 1411 architecture. 1412 141320140701: 1414 Commit r268115 has added NFSv4.1 server support, merged from 1415 projects/nfsv4.1-server. Since this includes changes to the 1416 internal interfaces between the NFS related modules, a full 1417 build of the kernel and modules will be necessary. 1418 __FreeBSD_version has been bumped. 1419 142020140629: 1421 The WITHOUT_VT_SUPPORT kernel config knob has been renamed 1422 WITHOUT_VT. (The other _SUPPORT knobs have a consistent meaning 1423 which differs from the behaviour controlled by this knob.) 1424 142520140619: 1426 Maximal length of the serial number in CTL was increased from 16 to 1427 64 chars, that breaks ABI. All CTL-related tools, such as ctladm 1428 and ctld, need to be rebuilt to work with a new kernel. 1429 143020140606: 1431 The libatf-c and libatf-c++ major versions were downgraded to 0 and 1432 1 respectively to match the upstream numbers. They were out of 1433 sync because, when they were originally added to FreeBSD, the 1434 upstream versions were not respected. These libraries are private 1435 and not yet built by default, so renumbering them should be a 1436 non-issue. However, unclean source trees will yield broken test 1437 programs once the operator executes "make delete-old-libs" after a 1438 "make installworld". 1439 1440 Additionally, the atf-sh binary was made private by moving it into 1441 /usr/libexec/. Already-built shell test programs will keep the 1442 path to the old binary so they will break after "make delete-old" 1443 is run. 1444 1445 If you are using WITH_TESTS=yes (not the default), wipe the object 1446 tree and rebuild from scratch to prevent spurious test failures. 1447 This is only needed once: the misnumbered libraries and misplaced 1448 binaries have been added to OptionalObsoleteFiles.inc so they will 1449 be removed during a clean upgrade. 1450 145120140512: 1452 Clang and llvm have been upgraded to 3.4.1 release. 1453 145420140508: 1455 We bogusly installed src.opts.mk in /usr/share/mk. This file should 1456 be removed to avoid issues in the future (and has been added to 1457 ObsoleteFiles.inc). 1458 145920140505: 1460 /etc/src.conf now affects only builds of the FreeBSD src tree. In the 1461 past, it affected all builds that used the bsd.*.mk files. The old 1462 behavior was a bug, but people may have relied upon it. To get this 1463 behavior back, you can .include /etc/src.conf from /etc/make.conf 1464 (which is still global and isn't changed). This also changes the 1465 behavior of incremental builds inside the tree of individual 1466 directories. Set MAKESYSPATH to ".../share/mk" to do that. 1467 Although this has survived make universe and some upgrade scenarios, 1468 other upgrade scenarios may have broken. At least one form of 1469 temporary breakage was fixed with MAKESYSPATH settings for buildworld 1470 as well... In cases where MAKESYSPATH isn't working with this 1471 setting, you'll need to set it to the full path to your tree. 1472 1473 One side effect of all this cleaning up is that bsd.compiler.mk 1474 is no longer implicitly included by bsd.own.mk. If you wish to 1475 use COMPILER_TYPE, you must now explicitly include bsd.compiler.mk 1476 as well. 1477 147820140430: 1479 The lindev device has been removed since /dev/full has been made a 1480 standard device. __FreeBSD_version has been bumped. 1481 148220140424: 1483 The knob WITHOUT_VI was added to the base system, which controls 1484 building ex(1), vi(1), etc. Older releases of FreeBSD required ex(1) 1485 in order to reorder files share/termcap and didn't build ex(1) as a 1486 build tool, so building/installing with WITH_VI is highly advised for 1487 build hosts for older releases. 1488 1489 This issue has been fixed in stable/9 and stable/10 in r277022 and 1490 r276991, respectively. 1491 149220140418: 1493 The YES_HESIOD knob has been removed. It has been obsolete for 1494 a decade. Please move to using WITH_HESIOD instead or your builds 1495 will silently lack HESIOD. 1496 149720140405: 1498 The uart(4) driver has been changed with respect to its handling 1499 of the low-level console. Previously the uart(4) driver prevented 1500 any process from changing the baudrate or the CLOCAL and HUPCL 1501 control flags. By removing the restrictions, operators can make 1502 changes to the serial console port without having to reboot. 1503 However, when getty(8) is started on the serial device that is 1504 associated with the low-level console, a misconfigured terminal 1505 line in /etc/ttys will now have a real impact. 1506 Before upgrading the kernel, make sure that /etc/ttys has the 1507 serial console device configured as 3wire without baudrate to 1508 preserve the previous behaviour. E.g: 1509 ttyu0 "/usr/libexec/getty 3wire" vt100 on secure 1510 151120140306: 1512 Support for libwrap (TCP wrappers) in rpcbind was disabled by default 1513 to improve performance. To re-enable it, if needed, run rpcbind 1514 with command line option -W. 1515 151620140226: 1517 Switched back to the GPL dtc compiler due to updates in the upstream 1518 dts files not being supported by the BSDL dtc compiler. You will need 1519 to rebuild your kernel toolchain to pick up the new compiler. Core dumps 1520 may result while building dtb files during a kernel build if you fail 1521 to do so. Set WITHOUT_GPL_DTC if you require the BSDL compiler. 1522 152320140216: 1524 Clang and llvm have been upgraded to 3.4 release. 1525 152620140216: 1527 The nve(4) driver has been removed. Please use the nfe(4) driver 1528 for NVIDIA nForce MCP Ethernet adapters instead. 1529 153020140212: 1531 An ABI incompatibility crept into the libc++ 3.4 import in r261283. 1532 This could cause certain C++ applications using shared libraries built 1533 against the previous version of libc++ to crash. The incompatibility 1534 has now been fixed, but any C++ applications or shared libraries built 1535 between r261283 and r261801 should be recompiled. 1536 153720140204: 1538 OpenSSH will now ignore errors caused by kernel lacking of Capsicum 1539 capability mode support. Please note that enabling the feature in 1540 kernel is still highly recommended. 1541 154220140131: 1543 OpenSSH is now built with sandbox support, and will use sandbox as 1544 the default privilege separation method. This requires Capsicum 1545 capability mode support in kernel. 1546 154720140128: 1548 The libelf and libdwarf libraries have been updated to newer 1549 versions from upstream. Shared library version numbers for 1550 these two libraries were bumped. Any ports or binaries 1551 requiring these two libraries should be recompiled. 1552 __FreeBSD_version is bumped to 1100006. 1553 155420140110: 1555 If a Makefile in a tests/ directory was auto-generating a Kyuafile 1556 instead of providing an explicit one, this would prevent such 1557 Makefile from providing its own Kyuafile in the future during 1558 NO_CLEAN builds. This has been fixed in the Makefiles but manual 1559 intervention is needed to clean an objdir if you use NO_CLEAN: 1560 # find /usr/obj -name Kyuafile | xargs rm -f 1561 156220131213: 1563 The behavior of gss_pseudo_random() for the krb5 mechanism 1564 has changed, for applications requesting a longer random string 1565 than produced by the underlying enctype's pseudo-random() function. 1566 In particular, the random string produced from a session key of 1567 enctype aes256-cts-hmac-sha1-96 or aes256-cts-hmac-sha1-96 will 1568 be different at the 17th octet and later, after this change. 1569 The counter used in the PRF+ construction is now encoded as a 1570 big-endian integer in accordance with RFC 4402. 1571 __FreeBSD_version is bumped to 1100004. 1572 157320131108: 1574 The WITHOUT_ATF build knob has been removed and its functionality 1575 has been subsumed into the more generic WITHOUT_TESTS. If you were 1576 using the former to disable the build of the ATF libraries, you 1577 should change your settings to use the latter. 1578 157920131025: 1580 The default version of mtree is nmtree which is obtained from 1581 NetBSD. The output is generally the same, but may vary 1582 slightly. If you found you need identical output adding 1583 "-F freebsd9" to the command line should do the trick. For the 1584 time being, the old mtree is available as fmtree. 1585 158620131014: 1587 libbsdyml has been renamed to libyaml and moved to /usr/lib/private. 1588 This will break ports-mgmt/pkg. Rebuild the port, or upgrade to pkg 1589 1.1.4_8 and verify bsdyml not linked in, before running "make 1590 delete-old-libs": 1591 # make -C /usr/ports/ports-mgmt/pkg build deinstall install clean 1592 or 1593 # pkg install pkg; ldd /usr/local/sbin/pkg | grep bsdyml 1594 159520131010: 1596 The stable/10 branch has been created in subversion from head 1597 revision r256279. 1598 1599COMMON ITEMS: 1600 1601 General Notes 1602 ------------- 1603 Avoid using make -j when upgrading. While generally safe, there are 1604 sometimes problems using -j to upgrade. If your upgrade fails with 1605 -j, please try again without -j. From time to time in the past there 1606 have been problems using -j with buildworld and/or installworld. This 1607 is especially true when upgrading between "distant" versions (eg one 1608 that cross a major release boundary or several minor releases, or when 1609 several months have passed on the -current branch). 1610 1611 Sometimes, obscure build problems are the result of environment 1612 poisoning. This can happen because the make utility reads its 1613 environment when searching for values for global variables. To run 1614 your build attempts in an "environmental clean room", prefix all make 1615 commands with 'env -i '. See the env(1) manual page for more details. 1616 1617 When upgrading from one major version to another it is generally best to 1618 upgrade to the latest code in the currently installed branch first, then 1619 do an upgrade to the new branch. This is the best-tested upgrade path, 1620 and has the highest probability of being successful. Please try this 1621 approach if you encounter problems with a major version upgrade. Since 1622 the stable 4.x branch point, one has generally been able to upgrade from 1623 anywhere in the most recent stable branch to head / current (or even the 1624 last couple of stable branches). See the top of this file when there's 1625 an exception. 1626 1627 When upgrading a live system, having a root shell around before 1628 installing anything can help undo problems. Not having a root shell 1629 around can lead to problems if pam has changed too much from your 1630 starting point to allow continued authentication after the upgrade. 1631 1632 This file should be read as a log of events. When a later event changes 1633 information of a prior event, the prior event should not be deleted. 1634 Instead, a pointer to the entry with the new information should be 1635 placed in the old entry. Readers of this file should also sanity check 1636 older entries before relying on them blindly. Authors of new entries 1637 should write them with this in mind. 1638 1639 ZFS notes 1640 --------- 1641 When upgrading the boot ZFS pool to a new version, always follow 1642 these two steps: 1643 1644 1.) recompile and reinstall the ZFS boot loader and boot block 1645 (this is part of "make buildworld" and "make installworld") 1646 1647 2.) update the ZFS boot block on your boot drive 1648 1649 The following example updates the ZFS boot block on the first 1650 partition (freebsd-boot) of a GPT partitioned drive ada0: 1651 "gpart bootcode -p /boot/gptzfsboot -i 1 ada0" 1652 1653 Non-boot pools do not need these updates. 1654 1655 To build a kernel 1656 ----------------- 1657 If you are updating from a prior version of FreeBSD (even one just 1658 a few days old), you should follow this procedure. It is the most 1659 failsafe as it uses a /usr/obj tree with a fresh mini-buildworld, 1660 1661 make kernel-toolchain 1662 make -DALWAYS_CHECK_MAKE buildkernel KERNCONF=YOUR_KERNEL_HERE 1663 make -DALWAYS_CHECK_MAKE installkernel KERNCONF=YOUR_KERNEL_HERE 1664 1665 To test a kernel once 1666 --------------------- 1667 If you just want to boot a kernel once (because you are not sure 1668 if it works, or if you want to boot a known bad kernel to provide 1669 debugging information) run 1670 make installkernel KERNCONF=YOUR_KERNEL_HERE KODIR=/boot/testkernel 1671 nextboot -k testkernel 1672 1673 To rebuild everything and install it on the current system. 1674 ----------------------------------------------------------- 1675 # Note: sometimes if you are running current you gotta do more than 1676 # is listed here if you are upgrading from a really old current. 1677 1678 <make sure you have good level 0 dumps> 1679 make buildworld 1680 make buildkernel KERNCONF=YOUR_KERNEL_HERE 1681 make installkernel KERNCONF=YOUR_KERNEL_HERE 1682 [1] 1683 <reboot in single user> [3] 1684 mergemaster -Fp [5] 1685 make installworld 1686 mergemaster -Fi [4] 1687 make delete-old [6] 1688 <reboot> 1689 1690 To cross-install current onto a separate partition 1691 -------------------------------------------------- 1692 # In this approach we use a separate partition to hold 1693 # current's root, 'usr', and 'var' directories. A partition 1694 # holding "/", "/usr" and "/var" should be about 2GB in 1695 # size. 1696 1697 <make sure you have good level 0 dumps> 1698 <boot into -stable> 1699 make buildworld 1700 make buildkernel KERNCONF=YOUR_KERNEL_HERE 1701 <maybe newfs current's root partition> 1702 <mount current's root partition on directory ${CURRENT_ROOT}> 1703 make installworld DESTDIR=${CURRENT_ROOT} -DDB_FROM_SRC 1704 make distribution DESTDIR=${CURRENT_ROOT} # if newfs'd 1705 make installkernel KERNCONF=YOUR_KERNEL_HERE DESTDIR=${CURRENT_ROOT} 1706 cp /etc/fstab ${CURRENT_ROOT}/etc/fstab # if newfs'd 1707 <edit ${CURRENT_ROOT}/etc/fstab to mount "/" from the correct partition> 1708 <reboot into current> 1709 <do a "native" rebuild/install as described in the previous section> 1710 <maybe install compatibility libraries from ports/misc/compat*> 1711 <reboot> 1712 1713 1714 To upgrade in-place from stable to current 1715 ---------------------------------------------- 1716 <make sure you have good level 0 dumps> 1717 make buildworld [9] 1718 make buildkernel KERNCONF=YOUR_KERNEL_HERE [8] 1719 make installkernel KERNCONF=YOUR_KERNEL_HERE 1720 [1] 1721 <reboot in single user> [3] 1722 mergemaster -Fp [5] 1723 make installworld 1724 mergemaster -Fi [4] 1725 make delete-old [6] 1726 <reboot> 1727 1728 Make sure that you've read the UPDATING file to understand the 1729 tweaks to various things you need. At this point in the life 1730 cycle of current, things change often and you are on your own 1731 to cope. The defaults can also change, so please read ALL of 1732 the UPDATING entries. 1733 1734 Also, if you are tracking -current, you must be subscribed to 1735 freebsd-current@freebsd.org. Make sure that before you update 1736 your sources that you have read and understood all the recent 1737 messages there. If in doubt, please track -stable which has 1738 much fewer pitfalls. 1739 1740 [1] If you have third party modules, such as vmware, you 1741 should disable them at this point so they don't crash your 1742 system on reboot. 1743 1744 [3] From the bootblocks, boot -s, and then do 1745 fsck -p 1746 mount -u / 1747 mount -a 1748 cd src 1749 adjkerntz -i # if CMOS is wall time 1750 Also, when doing a major release upgrade, it is required that 1751 you boot into single user mode to do the installworld. 1752 1753 [4] Note: This step is non-optional. Failure to do this step 1754 can result in a significant reduction in the functionality of the 1755 system. Attempting to do it by hand is not recommended and those 1756 that pursue this avenue should read this file carefully, as well 1757 as the archives of freebsd-current and freebsd-hackers mailing lists 1758 for potential gotchas. The -U option is also useful to consider. 1759 See mergemaster(8) for more information. 1760 1761 [5] Usually this step is a no-op. However, from time to time 1762 you may need to do this if you get unknown user in the following 1763 step. It never hurts to do it all the time. You may need to 1764 install a new mergemaster (cd src/usr.sbin/mergemaster && make 1765 install) after the buildworld before this step if you last updated 1766 from current before 20130425 or from -stable before 20130430. 1767 1768 [6] This only deletes old files and directories. Old libraries 1769 can be deleted by "make delete-old-libs", but you have to make 1770 sure that no program is using those libraries anymore. 1771 1772 [8] In order to have a kernel that can run the 4.x binaries needed to 1773 do an installworld, you must include the COMPAT_FREEBSD4 option in 1774 your kernel. Failure to do so may leave you with a system that is 1775 hard to boot to recover. A similar kernel option COMPAT_FREEBSD5 is 1776 required to run the 5.x binaries on more recent kernels. And so on 1777 for COMPAT_FREEBSD6 and COMPAT_FREEBSD7. 1778 1779 Make sure that you merge any new devices from GENERIC since the 1780 last time you updated your kernel config file. 1781 1782 [9] If CPUTYPE is defined in your /etc/make.conf, make sure to use the 1783 "?=" instead of the "=" assignment operator, so that buildworld can 1784 override the CPUTYPE if it needs to. 1785 1786 MAKEOBJDIRPREFIX must be defined in an environment variable, and 1787 not on the command line, or in /etc/make.conf. buildworld will 1788 warn if it is improperly defined. 1789FORMAT: 1790 1791This file contains a list, in reverse chronological order, of major 1792breakages in tracking -current. It is not guaranteed to be a complete 1793list of such breakages, and only contains entries since September 23, 2011. 1794If you need to see UPDATING entries from before that date, you will need 1795to fetch an UPDATING file from an older FreeBSD release. 1796 1797Copyright information: 1798 1799Copyright 1998-2009 M.
