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 1920210128: p13 FreeBSD-EN-21:01.tzdata 20 FreeBSD-EN-21:03.vnet 21 FreeBSD-SA-21:01.fsdisclosure 22 FreeBSD-SA-21:02.xenoom 23 24 Update timezone database information [EN-21:01.tzdata] 25 26 Panic when destroying VNET and epair simultaneously [EN-21:03.vnet] 27 28 Uninitialized file system kernel stack leaks [SA-21:01.fsdisclosure] 29 30 Xen guest-triggered out of memory [SA-21:02.xenoom] 31 3220201208: p12 FreeBSD-SA-20:33.openssl 33 34 Fix OpenSSL NULL pointer de-reference.

You can safely remove them from 193 your scripts, because they had no effect. 194 195 The vfs.fusefs.fix_broken_io, vfs.fusefs.sync_resize, 196 vfs.fusefs.refresh_size, vfs.fusefs.mmap_enable, 197 vfs.fusefs.reclaim_revoked, and vfs.fusefs.data_cache_invalidate 198 sysctls have been removed. If you felt the need to set any of them to 199 a non-default value, please tell [email protected] why. 200 20120190906: 202 The fuse(4) module has been renamed to fusefs(4) for consistency with 203 other filesystems. You should update any kld_load="fuse" entries in 204 /etc/rc.conf, fuse_load="YES" entries in /boot/loader.conf, and 205 "options FUSE" enties in kernel config files. 206 20720190811: 208 Default permissions on the /var/account/acct file (and copies of it 209 rotated by periodic daily scripts) are changed from 0644 to 0640 210 because the file contains sensitive information that should not be 211 world-readable. If the /var/account directory must be created by 212 rc.d/accounting, the mode used is now 0750. Admins who use the 213 accounting feature are encouraged to change the mode of an existing 214 /var/account directory to 0750 or 0700. 215 21620190723: 217 Clang, llvm, lld, lldb, compiler-rt, libc++, libunwind and openmp have 218 been upgraded to 8.0.1. Please see the 20141231 entry below for 219 information about prerequisites and upgrading, if you are not already 220 using clang 3.5.0 or higher. 221 22220190413: 223 Now Clang 8 has been merged (see the 20190412 entry below), the ifunc 224 functionality needed for the RETPOLINE option should work properly 225 again. The RETPOLINE option has been removed from BROKEN_OPTIONS. 226 22720190412: 228 Clang, llvm, lld, lldb, compiler-rt and libc++ have been upgraded to 229 8.0.0. Please see the 20141231 entry below for information about 230 prerequisites and upgrading, if you are not already using clang 3.5.0 231 or higher. 232 23320190307: 234 The RETPOLINE option produces non-functional ifunc-using binaries 235 with Clang 7.0.1, and has been forced off (via BROKEN_OPTIONS). 236 Once Clang 8 is merged it may be enabled again. 237 23820190216: 239 Clang, llvm, lld, lldb, compiler-rt and libc++ have been upgraded to 240 7.0.1. Please see the 20141231 entry below for information about 241 prerequisites and upgrading, if you are not already using clang 3.5.0 242 or higher. 243 24420190226: 245 geom_uzip(4) depends on the new module xz. If geom_uzip is statically 246 compiled into your custom kernel, add 'device xz' statement to the 247 kernel config. 248 24920190214: 250 Iflib is no longer unconditionally compiled into the kernel. Drivers 251 using iflib and statically compiled into the kernel, now require 252 the 'device iflib' config option. For the same drivers loaded as 253 modules on kernels not having 'device iflib', the iflib.ko module 254 is loaded automatically. 255 25620181228: 257 r342561 modifies the NFSv4 server so that it obeys vfs.nfsd.nfs_privport 258 in the same as it is applied to NFSv2 and 3. This implies that NFSv4 259 servers that have vfs.nfsd.nfs_privport set will only allow mounts 260 from clients using a reserved port#. Since both the FreeBSD and Linux 261 NFSv4 clients use reserved port#s by default, this should not affect 262 most NFSv4 mounts. 263 26420181129: 265 On amd64, arm64 and armv7 (architectures that install LLVM's ld.lld 266 linker as /usr/bin/ld) GNU ld is no longer installed as ld.bfd, as 267 it produces broken binaries when ifuncs are in use. Users needing 268 GNU ld should install the binutils port or package. 269 27020181115: 271 The set of CTM commands (ctm, ctm_smail, ctm_rmail, ctm_dequeue) 272 has been converted to a port (misc/ctm) and will be removed from 273 FreeBSD-13. A depreciation warning will be printed to stderr by 274 the ctm command, but the functionality will remain in base for all 275 FreeBSD-12 releases. 276 27720181019: 278 The stable/12 branch has been created in subversion from head 279 revision r339432. 280 28120181015: 282 Ports for the DRM modules have been simplified. Now, amd64 users should 283 just install the drm-kmod port. All others should install 284 drm-legacy-kmod. 285 286 Graphics hardware that's newer than about 2010 usually works with 287 drm-kmod. For hardware older than 2013, however, some users will need 288 to use drm-legacy-kmod if drm-kmod doesn't work for them. Hardware older 289 than 2008 usually only works in drm-legacy-kmod. The graphics team can 290 only commit to hardware made since 2013 due to the complexity of the 291 market and difficulty to test all the older cards effectively. If you 292 have hardware supported by drm-kmod, you are strongly encouraged to use 293 that as you will get better support. 294 295 Other than KPI chasing, drm-legacy-kmod will not be updated. As outlined 296 elsewhere, the drm and drm2 modules will be eliminated from the src base 297 soon (with a limited exception for arm). Please update to the package asap 298 and report any issues to [email protected]. 299 300 Generally, anybody using the drm*-kmod packages should add 301 WITHOUT_DRM_MODULE=t and WITHOUT_DRM2_MODULE=t to avoid nasty 302 cross-threading surprises, especially with automatic driver 303 loading from X11 startup. These will become the defaults in 13-current 304 shortly. 305 30620181012: 307 The ixlv(4) driver has been renamed to iavf(4). As a consequence, 308 custom kernel and module loading configuration files must be updated 309 accordingly. Moreover, interfaces previous presented as ixlvN to the 310 system are now exposed as iavfN and network configuration files must 311 be adjusted as necessary. 312 31320181009: 314 OpenSSL has been updated to version 1.1.1. This update included 315 additional various API changes througout the base system. It is 316 important to rebuild third-party software after upgrading. The value 317 of __FreeBSD_version has been bumped accordingly. 318 31920181006: 320 The legacy DRM modules and drivers have now been added to the loader's 321 module blacklist, in favor of loading them with kld_list in rc.conf(5). 322 The module blacklist may be overridden with the loader.conf(5) 323 'module_blacklist' variable, but loading them via rc.conf(5) is strongly 324 encouraged. 325 32620181002: 327 The cam(4) based nda(4) driver will be used over nvd(4) by default on 328 powerpc64. You may set 'options NVME_USE_NVD=1' in your kernel conf or 329 loader tunable 'hw.nvme.use_nvd=1' if you wish to use the existing 330 driver. Make sure to edit /boot/etc/kboot.conf and fstab to use the 331 nda device name. 332 33320180913: 334 Reproducible build mode is now on by default, in preparation for 335 FreeBSD 12.0. This eliminates build metadata such as the user, 336 host, and time from the kernel (and uname), unless the working tree 337 corresponds to a modified checkout from a version control system. 338 The previous behavior can be obtained by setting the /etc/src.conf 339 knob WITHOUT_REPRODUCIBLE_BUILD. 340 34120180826: 342 The Yarrow CSPRNG has been removed from the kernel as it has not been 343 supported by its designers since at least 2003. Fortuna has been the 344 default since FreeBSD-11. 345 34620180822: 347 devctl freeze/thaw have gone into the tree, the rc scripts have been 348 updated to use them and devmatch has been changed. You should update 349 kernel, userland and rc scripts all at the same time. 350 35120180818: 352 The default interpreter has been switched from 4th to Lua. 353 LOADER_DEFAULT_INTERP, documented in build(7), will override the default 354 interpreter. If you have custom FORTH code you will need to set 355 LOADER_DEFAULT_INTERP=4th (valid values are 4th, lua or simp) in 356 src.conf for the build. This will create default hard links between 357 loader and loader_4th instead of loader and loader_lua, the new default. 358 If you are using UEFI it will create the proper hard link to loader.efi. 359 360 bhyve uses userboot.so. It remains 4th-only until some issues are solved 361 regarding coexisting with multiple versions of FreeBSD are resolved. 362 36320180815: 364 ls(1) now respects the COLORTERM environment variable used in other 365 systems and software to indicate that a colored terminal is both 366 supported and desired. If ls(1) is suddenly emitting colors, they may 367 be disabled again by either removing the unwanted COLORTERM from your 368 environment, or using `ls --color=never`. The ls(1) specific CLICOLOR 369 may not be observed in a future release. 370 37120180808: 372 The default pager for most commands has been changed to "less". To 373 restore the old behavior, set PAGER="more" and MANPAGER="more -s" in 374 your environment. 375 37620180731: 377 The jedec_ts(4) driver has been removed. A superset of its functionality 378 is available in the jedec_dimm(4) driver, and the manpage for that 379 driver includes migration instructions. If you have "device jedec_ts" 380 in your kernel configuration file, it must be removed. 381 38220180730: 383 amd64/GENERIC now has EFI runtime services, EFIRT, enabled by default. 384 This should have no effect if the kernel is booted via BIOS/legacy boot. 385 EFIRT may be disabled via a loader tunable, efi.rt.disabled, if a system 386 has a buggy firmware that prevents a successful boot due to use of 387 runtime services. 388 38920180727: 390 Atmel AT91RM9200 and AT91SAM9, Cavium CNS 11xx and XScale 391 support has been removed from the tree. These ports were 392 obsolete and/or known to be broken for many years. 393 39420180723: 395 loader.efi has been augmented to participate more fully in the 396 UEFI boot manager protocol. loader.efi will now look at the 397 BootXXXX environment variable to determine if a specific kernel 398 or root partition was specified. XXXX is derived from BootCurrent. 399 efibootmgr(8) manages these standard UEFI variables. 400 40120180720: 402 zfsloader's functionality has now been folded into loader. 403 zfsloader is no longer necessary once you've updated your 404 boot blocks. For a transition period, we will install a 405 hardlink for zfsloader to loader to allow a smooth transition 406 until the boot blocks can be updated (hard link because old 407 zfs boot blocks don't understand symlinks). 408 40920180719: 410 ARM64 now have efifb support, if you want to have serial console 411 on your arm64 board when an screen is connected and the bootloader 412 setup a frambuffer for us to use, just add : 413 boot_serial=YES 414 boot_multicons=YES 415 in /boot/loader.conf 416 For Raspberry Pi 3 (RPI) users, this is needed even if you don't have 417 an screen connected as the firmware will setup a framebuffer are that 418 u-boot will expose as an EFI framebuffer. 419 42020180719: 421 New uid:gid added, ntpd:ntpd (123:123). Be sure to run mergemaster 422 or take steps to update /etc/passwd before doing installworld on 423 existing systems. Do not skip the "mergemaster -Fp" step before 424 installworld, as described in the update procedures near the bottom 425 of this document. Also, rc.d/ntpd now starts ntpd(8) as user ntpd 426 if the new mac_ntpd(4) policy is available, unless ntpd_flags or 427 the ntp config file contain options that change file/dir locations. 428 When such options (e.g., "statsdir" or "crypto") are used, ntpd can 429 still be run as non-root by setting ntpd_user=ntpd in rc.conf, after 430 taking steps to ensure that all required files/dirs are accessible 431 by the ntpd user. 432 43320180717: 434 Big endian arm support has been removed. 435 43620180711: 437 The static environment setup in kernel configs is no longer mutually 438 exclusive with the loader(8) environment by default. In order to 439 restore the previous default behavior of disabling the loader(8) 440 environment if a static environment is present, you must specify 441 loader_env.disabled=1 in the static environment. 442 44320180705: 444 The ABI of syscalls used by management tools like sockstat and 445 netstat has been broken to allow 32-bit binaries to work on 446 64-bit kernels without modification. These programs will need 447 to match the kernel in order to function. External programs may 448 require minor modifications to accommodate a change of type in 449 structures from pointers to 64-bit virtual addresses. 450 45120180702: 452 On i386 and amd64 atomics are now inlined. Out of tree modules using 453 atomics will need to be rebuilt. 454 45520180701: 456 The '%I' format in the kern.corefile sysctl limits the number of 457 core files that a process can generate to the number stored in the 458 debug.ncores sysctl. The '%I' format is replaced by the single digit 459 index. Previously, if all indexes were taken the kernel would overwrite 460 only a core file with the highest index in a filename. 461 Currently the system will create a new core file if there is a free 462 index or if all slots are taken it will overwrite the oldest one. 463 46420180630: 465 Clang, llvm, lld, lldb, compiler-rt and libc++ have been upgraded to 466 6.0.1. Please see the 20141231 entry below for information about 467 prerequisites and upgrading, if you are not already using clang 3.5.0 468 or higher. 469 47020180628: 471 r335753 introduced a new quoting method. However, etc/devd/devmatch.conf 472 needed to be changed to work with it. This change was made with r335763 473 and requires a mergemaster / etcupdate / etc to update the installed file. 474 47520180612: 476 r334930 changed the interface between the NFS modules, so they all 477 need to be rebuilt. r335018 did a __FreeBSD_version bump for this. 478 47920180530: 480 As of r334391 lld is the default amd64 system linker; it is installed 481 as /usr/bin/ld. Kernel build workarounds (see 20180510 entry) are no 482 longer necessary. 483 48420180530: 485 The kernel / userland interface for devinfo changed, so you'll 486 need a new kernel and userland as a pair for it to work (rebuilding 487 lib/libdevinfo is all that's required). devinfo and devmatch will 488 not work, but everything else will when there's a mismatch. 489 49020180523: 491 The on-disk format for hwpmc callchain records has changed to include 492 threadid corresponding to a given record. This changes the field offsets 493 and thus requires that libpmcstat be rebuilt before using a kernel 494 later than r334108. 495 49620180517: 497 The vxge(4) driver has been removed. This driver was introduced into 498 HEAD one week before the Exar left the Ethernet market and is not 499 known to be used. If you have device vxge in your kernel config file 500 it must be removed. 501 50220180510: 503 The amd64 kernel now requires a ld that supports ifunc to produce a 504 working kernel, either lld or a newer binutils. lld is built by default 505 on amd64, and the 'buildkernel' target uses it automatically. However, 506 it is not the default linker, so building the kernel the traditional 507 way requires LD=ld.lld on the command line (or LD=/usr/local/bin/ld for 508 binutils port/package). lld will soon be default, and this requirement 509 will go away. 510 511 NOTE: As of r334391 lld is the default system linker on amd64, and no 512 workaround is necessary. 513 51420180508: 515 The nxge(4) driver has been removed. This driver was for PCI-X 10g 516 cards made by s2io/Neterion. The company was aquired by Exar and 517 no longer sells or supports Ethernet products. If you have device 518 nxge in your kernel config file it must be removed. 519 52020180504: 521 The tz database (tzdb) has been updated to 2018e. This version more 522 correctly models time stamps in time zones with negative DST such as 523 Europe/Dublin (from 1971 on), Europe/Prague (1946/7), and 524 Africa/Windhoek (1994/2017). This does not affect the UT offsets, only 525 time zone abbreviations and the tm_isdst flag. 526 52720180502: 528 The ixgb(4) driver has been removed. This driver was for an early and 529 uncommon legacy PCI 10GbE for a single ASIC, Intel 82597EX. Intel 530 quickly shifted to the long lived ixgbe family. If you have device 531 ixgb in your kernel config file it must be removed. 532 53320180501: 534 The lmc(4) driver has been removed. This was a WAN interface 535 card that was already reportedly rare in 2003, and had an ambiguous 536 license. If you have device lmc in your kernel config file it must 537 be removed. 538 53920180413: 540 Support for Arcnet networks has been removed. If you have device 541 arcnet or device cm in your kernel config file they must be 542 removed. 543 54420180411: 545 Support for FDDI networks has been removed. If you have device 546 fddi or device fpa in your kernel config file they must be 547 removed. 548 54920180406: 550 In addition to supporting RFC 3164 formatted messages, the 551 syslogd(8) service is now capable of parsing RFC 5424 formatted 552 log messages. The main benefit of using RFC 5424 is that clients 553 may now send log messages with timestamps containing year numbers, 554 microseconds and time zone offsets. 555 556 Similarly, the syslog(3) C library function has been altered to 557 send RFC 5424 formatted messages to the local system logging 558 daemon. On systems using syslogd(8), this change should have no 559 negative impact, as long as syslogd(8) and the C library are 560 updated at the same time. On systems using a different system 561 logging daemon, it may be necessary to make configuration 562 adjustments, depending on the software used. 563 564 When using syslog-ng, add the 'syslog-protocol' flag to local 565 input sources to enable parsing of RFC 5424 formatted messages: 566 567 source src { 568 unix-dgram("/var/run/log" flags(syslog-protocol)); 569 } 570 571 When using rsyslog, disable the 'SysSock.UseSpecialParser' option 572 of the 'imuxsock' module to let messages be processed by the 573 regular RFC 3164/5424 parsing pipeline: 574 575 module(load="imuxsock" SysSock.UseSpecialParser="off") 576 577 Do note that these changes only affect communication between local 578 applications and syslogd(8). The format that syslogd(8) uses to 579 store messages on disk or forward messages to other systems 580 remains unchanged. syslogd(8) still uses RFC 3164 for these 581 purposes. Options to customize this behaviour will be added in the 582 future. Utilities that process log files stored in /var/log are 583 thus expected to continue to function as before. 584 585 __FreeBSD_version has been incremented to 1200061 to denote this 586 change. 587 58820180328: 589 Support for token ring networks has been removed. If you 590 have "device token" in your kernel config you should remove 591 it. No device drivers supported token ring. 592 59320180323: 594 makefs was modified to be able to tag ISO9660 El Torito boot catalog 595 entries as EFI instead of overloading the i386 tag as done previously. 596 The amd64 mkisoimages.sh script used to build amd64 ISO images for 597 release was updated to use this. This may mean that makefs must be 598 updated before "make cdrom" can be run in the release directory. This 599 should be as simple as: 600 601 $ cd $SRCDIR/usr.sbin/makefs 602 $ make depend all install 603 60420180212: 605 FreeBSD boot loader enhanced with Lua scripting. It's purely opt-in for 606 now by building WITH_LOADER_LUA and WITHOUT_FORTH in /etc/src.conf. 607 Co-existance for the transition period will come shortly. Booting is a 608 complex environment and test coverage for Lua-enabled loaders has been 609 thin, so it would be prudent to assume it might not work and make 610 provisions for backup boot methods. 611 61220180211: 613 devmatch functionality has been turned on in devd. It will automatically 614 load drivers for unattached devices. This may cause unexpected drivers to 615 be loaded. Please report any problems to current@ and [email protected]. 616 61720180114: 618 Clang, llvm, lld, lldb, compiler-rt and libc++ have been upgraded to 619 6.0.0. Please see the 20141231 entry below for information about 620 prerequisites and upgrading, if you are not already using clang 3.5.0 621 or higher. 622 62320180110: 624 LLVM's lld linker is now used as the FreeBSD/amd64 bootstrap linker. 625 This means it is used to link the kernel and userland libraries and 626 executables, but is not yet installed as /usr/bin/ld by default. 627 628 To revert to ld.bfd as the bootstrap linker, in /etc/src.conf set 629 WITHOUT_LLD_BOOTSTRAP=yes 630 63120180110: 632 On i386, pmtimer has been removed. Its functionality has been folded 633 into apm. It was a no-op on ACPI in current for a while now (but was still 634 needed on i386 in FreeBSD 11 and earlier). Users may need to remove it 635 from kernel config files. 636 63720180104: 638 The use of RSS hash from the network card aka flowid has been 639 disabled by default for lagg(4) as it's currently incompatible with 640 the lacp and loadbalance protocols. 641 642 This can be re-enabled by setting the following in loader.conf: 643 net.link.lagg.default_use_flowid="1" 644 64520180102: 646 The SW_WATCHDOG option is no longer necessary to enable the 647 hardclock-based software watchdog if no hardware watchdog is 648 configured. As before, SW_WATCHDOG will cause the software 649 watchdog to be enabled even if a hardware watchdog is configured. 650 65120171215: 652 r326887 fixes the issue described in the 20171214 UPDATING entry. 653 r326888 flips the switch back to building GELI support always. 654 65520171214: 656 r362593 broke ZFS + GELI support for reasons unknown. However, 657 it also broke ZFS support generally, so GELI has been turned off 658 by default as the lesser evil in r326857. If you boot off ZFS and/or 659 GELI, it might not be a good time to update. 660 66120171125: 662 PowerPC users must update loader(8) by rebuilding world before 663 installing a new kernel, as the protocol connecting them has 664 changed. Without the update, loader metadata will not be passed 665 successfully to the kernel and users will have to enter their 666 root partition at the kernel mountroot prompt to continue booting. 667 Newer versions of loader can boot old kernels without issue. 668 66920171110: 670 The LOADER_FIREWIRE_SUPPORT build variable as been renamed to 671 WITH/OUT_LOADER_FIREWIRE. LOADER_{NO_,}GELI_SUPPORT has been renamed 672 to WITH/OUT_LOADER_GELI. 673 67420171106: 675 The naive and non-compliant support of posix_fallocate(2) in ZFS 676 has been removed as of r325320. The system call now returns EINVAL 677 when used on a ZFS file. Although the new behavior complies with the 678 standard, some consumers are not prepared to cope with it. 679 One known victim is lld prior to r325420. 680 68120171102: 682 Building in a FreeBSD src checkout will automatically create object 683 directories now rather than store files in the current directory if 684 'make obj' was not ran. Calling 'make obj' is no longer necessary. 685 This feature can be disabled by setting WITHOUT_AUTO_OBJ=yes in 686 /etc/src-env.conf (not /etc/src.conf), or passing the option in the 687 environment. 688 68920171101: 690 The default MAKEOBJDIR has changed from /usr/obj/<srcdir> for native 691 builds, and /usr/obj/<arch>/<srcdir> for cross-builds, to a unified 692 /usr/obj/<srcdir>/<arch>. This behavior can be changed to the old 693 format by setting WITHOUT_UNIFIED_OBJDIR=yes in /etc/src-env.conf, 694 the environment, or with -DWITHOUT_UNIFIED_OBJDIR when building. 695 The UNIFIED_OBJDIR option is a transitional feature that will be 696 removed for 12.0 release; please migrate to the new format for any 697 tools by looking up the OBJDIR used by 'make -V .OBJDIR' means rather 698 than hardcoding paths. 699 70020171028: 701 The native-xtools target no longer installs the files by default to the 702 OBJDIR. Use the native-xtools-install target with a DESTDIR to install 703 to ${DESTDIR}/${NXTP} where NXTP defaults to /nxb-bin. 704 70520171021: 706 As part of the boot loader infrastructure cleanup, LOADER_*_SUPPORT 707 options are changing from controlling the build if defined / undefined 708 to controlling the build with explicit 'yes' or 'no' values. They will 709 shift to WITH/WITHOUT options to match other options in the system. 710 71120171010: 712 libstand has turned into a private library for sys/boot use only. 713 It is no longer supported as a public interface outside of sys/boot. 714 71520171005: 716 The arm port has split armv6 into armv6 and armv7. armv7 is now 717 a valid TARGET_ARCH/MACHINE_ARCH setting. If you have an armv7 system 718 and are running a kernel from before r324363, you will need to add 719 MACHINE_ARCH=armv7 to 'make buildworld' to do a native build. 720 72120171003: 722 When building multiple kernels using KERNCONF, non-existent KERNCONF 723 files will produce an error and buildkernel will fail. Previously 724 missing KERNCONF files silently failed giving no indication as to 725 why, only to subsequently discover during installkernel that the 726 desired kernel was never built in the first place. 727 72820170912: 729 The default serial number format for CTL LUNs has changed. This will 730 affect users who use /dev/diskid/* device nodes, or whose FibreChannel 731 or iSCSI clients care about their LUNs' serial numbers. Users who 732 require serial number stability should hardcode serial numbers in 733 /etc/ctl.conf . 734 73520170912: 736 For 32-bit arm compiled for hard-float support, soft-floating point 737 binaries now always get their shared libraries from 738 LD_SOFT_LIBRARY_PATH (in the past, this was only used if 739 /usr/libsoft also existed). Only users with a hard-float ld.so, but 740 soft-float everything else should be affected. 741 74220170826: 743 The geli password typed at boot is now hidden. To restore the previous 744 behavior, see geli(8) for configuration options. 745 74620170825: 747 Move PMTUD blackhole counters to TCPSTATS and remove them from bare 748 sysctl values. Minor nit, but requires a rebuild of both world/kernel 749 to complete. 750 75120170814: 752 "make check" behavior (made in ^/head@r295380) has been changed to 753 execute from a limited sandbox, as opposed to executing from 754 ${TESTSDIR}. 755 756 Behavioral changes: 757 - The "beforecheck" and "aftercheck" targets are now specified. 758 - ${CHECKDIR} (added in commit noted above) has been removed. 759 - Legacy behavior can be enabled by setting 760 WITHOUT_MAKE_CHECK_USE_SANDBOX in src.conf(5) or the environment. 761 762 If the limited sandbox mode is enabled, "make check" will execute 763 "make distribution", then install, execute the tests, and clean up the 764 sandbox if successful. 765 766 The "make distribution" and "make install" targets are typically run as 767 root to set appropriate permissions and ownership at installation time. 768 The end-user should set "WITH_INSTALL_AS_USER" in src.conf(5) or the 769 environment if executing "make check" with limited sandbox mode using 770 an unprivileged user. 771 77220170808: 773 Since the switch to GPT disk labels, fsck for UFS/FFS has been 774 unable to automatically find alternate superblocks. As of r322297, 775 the information needed to find alternate superblocks has been 776 moved to the end of the area reserved for the boot block. 777 Filesystems created with a newfs of this vintage or later 778 will create the recovery information. If you have a filesystem 779 created prior to this change and wish to have a recovery block 780 created for your filesystem, you can do so by running fsck in 781 foreground mode (i.e., do not use the -p or -y options). As it 782 starts, fsck will ask ``SAVE DATA TO FIND ALTERNATE SUPERBLOCKS'' 783 to which you should answer yes. 784 78520170728: 786 As of r321665, an NFSv4 server configuration that services 787 Kerberos mounts or clients that do not support the uid/gid in 788 owner/owner_group string capability, must explicitly enable 789 the nfsuserd daemon by adding nfsuserd_enable="YES" to the 790 machine's /etc/rc.conf file. 791 79220170722: 793 Clang, llvm, lldb, compiler-rt and libc++ have been upgraded to 5.0.0. 794 Please see the 20141231 entry below for information about prerequisites 795 and upgrading, if you are not already using clang 3.5.0 or higher. 796 79720170701: 798 WITHOUT_RCMDS is now the default. Set WITH_RCMDS if you need the 799 r-commands (rlogin, rsh, etc.) to be built with the base system. 800 80120170625: 802 The FreeBSD/powerpc platform now uses a 64-bit type for time_t. This is 803 a very major ABI incompatible change, so users of FreeBSD/powerpc must 804 be careful when performing source upgrades. It is best to run 805 'make installworld' from an alternate root system, either a live 806 CD/memory stick, or a temporary root partition. Additionally, all ports 807 must be recompiled. powerpc64 is largely unaffected, except in the case 808 of 32-bit compatibility. All 32-bit binaries will be affected. 809 81020170623: 811 Forward compatibility for the "ino64" project have been committed. This 812 will allow most new binaries to run on older kernels in a limited 813 fashion. This prevents many of the common foot-shooting actions in the 814 upgrade as well as the limited ability to roll back the kernel across 815 the ino64 upgrade. Complicated use cases may not work properly, though 816 enough simpler ones work to allow recovery in most situations. 817 81820170620: 819 Switch back to the BSDL dtc (Device Tree Compiler). Set WITH_GPL_DTC 820 if you require the GPL compiler. 821 82220170618: 823 The internal ABI used for communication between the NFS kernel modules 824 was changed by r320085, so __FreeBSD_version was bumped to 825 ensure all the NFS related modules are updated together. 826 82720170617: 828 The ABI of struct event was changed by extending the data 829 member to 64bit and adding ext fields. For upgrade, same 830 precautions as for the entry 20170523 "ino64" must be 831 followed. 832 83320170531: 834 The GNU roff toolchain has been removed from base. To render manpages 835 which are not supported by mandoc(1), man(1) can fallback on GNU roff 836 from ports (and recommends to install it). 837 To render roff(7) documents, consider using GNU roff from ports or the 838 heirloom doctools roff toolchain from ports via pkg install groff or 839 via pkg install heirloom-doctools. 840 84120170524: 842 The ath(4) and ath_hal(4) modules now build piecemeal to allow for 843 smaller runtime footprint builds. This is useful for embedded systems 844 which only require one chipset support. 845 846 If you load it as a module, make sure this is in /boot/loader.conf: 847 848 if_ath_load="YES" 849 850 This will load the HAL, all chip/RF backends and if_ath_pci. 851 If you have if_ath_pci in /boot/loader.conf, ensure it is after 852 if_ath or it will not load any HAL chipset support. 853 854 If you want to selectively load things (eg on ye cheape ARM/MIPS 855 platforms where RAM is at a premium) you should: 856 857 * load ath_hal 858 * load the chip modules in question 859 * load ath_rate, ath_dfs 860 * load ath_main 861 * load if_ath_pci and/or if_ath_ahb depending upon your particular 862 bus bind type - this is where probe/attach is done. 863 864 For further comments/feedback, poke adrian@ . 865 86620170523: 867 The "ino64" 64-bit inode project has been committed, which extends 868 a number of types to 64 bits. Upgrading in place requires care and 869 adherence to the documented upgrade procedure. 870 871 If using a custom kernel configuration ensure that the 872 COMPAT_FREEBSD11 option is included (as during the upgrade the 873 system will be running the ino64 kernel with the existing world). 874 875 For the safest in-place upgrade begin by removing previous build 876 artifacts via "rm -rf /usr/obj/*". Then, carefully follow the 877 full procedure documented below under the heading "To rebuild 878 everything and install it on the current system." Specifically, 879 a reboot is required after installing the new kernel before 880 installing world. 881 88220170424: 883 The NATM framework including the en(4), fatm(4), hatm(4), and 884 patm(4) devices has been removed. Consumers should plan a 885 migration before the end-of-life date for FreeBSD 11. 886 88720170420: 888 GNU diff has been replaced by a BSD licensed diff. Some features of GNU 889 diff has not been implemented, if those are needed a newer version of 890 GNU diff is available via the diffutils package under the gdiff name. 891 89220170413: 893 As of r316810 for ipfilter, keep frags is no longer assumed when 894 keep state is specified in a rule. r316810 aligns ipfilter with 895 documentation in man pages separating keep frags from keep state. 896 This allows keep state to be specified without forcing keep frags 897 and allows keep frags to be specified independently of keep state. 898 To maintain previous behaviour, also specify keep frags with 899 keep state (as documented in ipf.conf.5). 900 90120170407: 902 arm64 builds now use the base system LLD 4.0.0 linker by default, 903 instead of requiring that the aarch64-binutils port or package be 904 installed. To continue using aarch64-binutils, set 905 CROSS_BINUTILS_PREFIX=/usr/local/aarch64-freebsd/bin . 906 90720170405: 908 The UDP optimization in entry 20160818 that added the sysctl 909 net.inet.udp.require_l2_bcast has been reverted. L2 broadcast 910 packets will no longer be treated as L3 broadcast packets. 911 91220170331: 913 Binds and sends to the loopback addresses, IPv6 and IPv4, will now 914 use any explicitly assigned loopback address available in the jail 915 instead of using the first assigned address of the jail. 916 91720170329: 918 The ctl.ko module no longer implements the iSCSI target frontend: 919 cfiscsi.ko does instead. 920 921 If building cfiscsi.ko as a kernel module, the module can be loaded 922 via one of the following methods: 923 - `cfiscsi_load="YES"` in loader.conf(5). 924 - Add `cfiscsi` to `$kld_list` in rc.conf(5). 925 - ctladm(8)/ctld(8), when compiled with iSCSI support 926 (`WITH_ISCSI=yes` in src.conf(5)) 927 928 Please see cfiscsi(4) for more details. 929 93020170316: 931 The mmcsd.ko module now additionally depends on geom_flashmap.ko. 932 Also, mmc.ko and mmcsd.ko need to be a matching pair built from the 933 same source (previously, the dependency of mmcsd.ko on mmc.ko was 934 missing, but mmcsd.ko now will refuse to load if it is incompatible 935 with mmc.ko). 936 93720170315: 938 The syntax of ipfw(8) named states was changed to avoid ambiguity. 939 If you have used named states in the firewall rules, you need to modify 940 them after installworld and before rebooting. Now named states must 941 be prefixed with colon. 942 94320170311: 944 The old drm (sys/dev/drm/) drivers for i915 and radeon have been 945 removed as the userland we provide cannot use them. The KMS version 946 (sys/dev/drm2) supports the same hardware. 947 94820170302: 949 Clang, llvm, lldb, compiler-rt and libc++ have been upgraded to 4.0.0. 950 Please see the 20141231 entry below for information about prerequisites 951 and upgrading, if you are not already using clang 3.5.0 or higher. 952 95320170221: 954 The code that provides support for ZFS .zfs/ directory functionality 955 has been reimplemented. It's not possible now to create a snapshot 956 by mkdir under .zfs/snapshot/. That should be the only user visible 957 change. 958 95920170216: 960 EISA bus support has been removed. The WITH_EISA option is no longer 961 valid. 962 96320170215: 964 MCA bus support has been removed. 965 96620170127: 967 The WITH_LLD_AS_LD / WITHOUT_LLD_AS_LD build knobs have been renamed 968 WITH_LLD_IS_LD / WITHOUT_LLD_IS_LD, for consistency with CLANG_IS_CC. 969 97020170112: 971 The EM_MULTIQUEUE kernel configuration option is deprecated now that 972 the em(4) driver conforms to iflib specifications. 973 97420170109: 975 The igb(4), em(4) and lem(4) ethernet drivers are now implemented via 976 IFLIB. If you have a custom kernel configuration that excludes em(4) 977 but you use igb(4), you need to re-add em(4) to your custom configuration. 978 97920161217: 980 Clang, llvm, lldb, compiler-rt and libc++ have been upgraded to 3.9.1. 981 Please see the 20141231 entry below for information about prerequisites 982 and upgrading, if you are not already using clang 3.5.0 or higher. 983 98420161124: 985 Clang, llvm, lldb, compiler-rt and libc++ have been upgraded to 3.9.0. 986 Please see the 20141231 entry below for information about prerequisites 987 and upgrading, if you are not already using clang 3.5.0 or higher. 988 98920161119: 990 The layout of the pmap structure has changed for powerpc to put the pmap 991 statistics at the front for all CPU variations. libkvm(3) and all tools 992 that link against it need to be recompiled. 993 99420161030: 995 isl(4) and cyapa(4) drivers now require a new driver, 996 chromebook_platform(4), to work properly on Chromebook-class hardware. 997 On other types of hardware the drivers may need to be configured using 998 device hints. Please see the corresponding manual pages for details. 999 100020161017: 1001 The urtwn(4) driver was merged into rtwn(4) and now consists of 1002 rtwn(4) main module + rtwn_usb(4) and rtwn_pci(4) bus-specific 1003 parts. 1004 Also, firmware for RTL8188CE was renamed due to possible name 1005 conflict (rtwnrtl8192cU(B) -> rtwnrtl8192cE(B)) 1006 100720161015: 1008 GNU rcs has been removed from base. It is available as packages: 1009 - rcs: Latest GPLv3 GNU rcs version. 1010 - rcs57: Copy of the latest version of GNU rcs (GPLv2) before it was 1011 removed from base. 1012 101320161008: 1014 Use of the cc_cdg, cc_chd, cc_hd, or cc_vegas congestion control 1015 modules now requires that the kernel configuration contain the 1016 TCP_HHOOK option. (This option is included in the GENERIC kernel.) 1017 101820161003: 1019 The WITHOUT_ELFCOPY_AS_OBJCOPY src.conf(5) knob has been retired. 1020 ELF Tool Chain's elfcopy is always installed as /usr/bin/objcopy. 1021 102220160924: 1023 Relocatable object files with the extension of .So have been renamed 1024 to use an extension of .pico instead. The purpose of this change is 1025 to avoid a name clash with shared libraries on case-insensitive file 1026 systems. On those file systems, foo.So is the same file as foo.so. 1027 102820160918: 1029 GNU rcs has been turned off by default. It can (temporarily) be built 1030 again by adding WITH_RCS knob in src.conf. 1031 Otherwise, GNU rcs is available from packages: 1032 - rcs: Latest GPLv3 GNU rcs version. 1033 - rcs57: Copy of the latest version of GNU rcs (GPLv2) from base. 1034 103520160918: 1036 The backup_uses_rcs functionality has been removed from rc.subr. 1037 103820160908: 1039 The queue(3) debugging macro, QUEUE_MACRO_DEBUG, has been split into 1040 two separate components, QUEUE_MACRO_DEBUG_TRACE and 1041 QUEUE_MACRO_DEBUG_TRASH. Define both for the original 1042 QUEUE_MACRO_DEBUG behavior. 1043 104420160824: 1045 r304787 changed some ioctl interfaces between the iSCSI userspace 1046 programs and the kernel. ctladm, ctld, iscsictl, and iscsid must be 1047 rebuilt to work with new kernels. __FreeBSD_version has been bumped 1048 to 1200005. 1049 105020160818: 1051 The UDP receive code has been updated to only treat incoming UDP 1052 packets that were addressed to an L2 broadcast address as L3 1053 broadcast packets. It is not expected that this will affect any 1054 standards-conforming UDP application. The new behaviour can be 1055 disabled by setting the sysctl net.inet.udp.require_l2_bcast to 1056 0. 1057 105820160818: 1059 Remove the openbsd_poll system call. 1060 __FreeBSD_version has been bumped because of this. 1061 106220160708: 1063 The stable/11 branch has been created from head@r302406. 1064 106520160622: 1066 The libc stub for the pipe(2) system call has been replaced with 1067 a wrapper that calls the pipe2(2) system call and the pipe(2) 1068 system call is now only implemented by the kernels that include 1069 "options COMPAT_FREEBSD10" in their config file (this is the 1070 default). Users should ensure that this option is enabled in 1071 their kernel or upgrade userspace to r302092 before upgrading their 1072 kernel. 1073 107420160527: 1075 CAM will now strip leading spaces from SCSI disks' serial numbers. 1076 This will affect users who create UFS filesystems on SCSI disks using 1077 those disk's diskid device nodes. For example, if /etc/fstab 1078 previously contained a line like 1079 "/dev/diskid/DISK-%20%20%20%20%20%20%20ABCDEFG0123456", you should 1080 change it to "/dev/diskid/DISK-ABCDEFG0123456". Users of geom 1081 transforms like gmirror may also be affected. ZFS users should 1082 generally be fine. 1083 108420160523: 1085 The bitstring(3) API has been updated with new functionality and 1086 improved performance. But it is binary-incompatible with the old API. 1087 Objects built with the new headers may not be linked against objects 1088 built with the old headers. 1089 109020160520: 1091 The brk and sbrk functions have been removed from libc on arm64. 1092 Binutils from ports has been updated to not link to these 1093 functions and should be updated to the latest version before 1094 installing a new libc. 1095 109620160517: 1097 The armv6 port now defaults to hard float ABI. Limited support 1098 for running both hardfloat and soft float on the same system 1099 is available using the libraries installed with -DWITH_LIBSOFT. 1100 This has only been tested as an upgrade path for installworld 1101 and packages may fail or need manual intervention to run. New 1102 packages will be needed. 1103 1104 To update an existing self-hosted armv6hf system, you must add 1105 TARGET_ARCH=armv6 on the make command line for both the build 1106 and the install steps. 1107 110820160510: 1109 Kernel modules compiled outside of a kernel build now default to 1110 installing to /boot/modules instead of /boot/kernel. Many kernel 1111 modules built this way (such as those in ports) already overrode 1112 KMODDIR explicitly to install into /boot/modules. However, 1113 manually building and installing a module from /sys/modules will 1114 now install to /boot/modules instead of /boot/kernel. 1115 111620160414: 1117 The CAM I/O scheduler has been committed to the kernel. There should be 1118 no user visible impact. This does enable NCQ Trim on ada SSDs. While the 1119 list of known rogues that claim support for this but actually corrupt 1120 data is believed to be complete, be on the lookout for data 1121 corruption. The known rogue list is believed to be complete: 1122 1123 o Crucial MX100, M550 drives with MU01 firmware. 1124 o Micron M510 and M550 drives with MU01 firmware. 1125 o Micron M500 prior to MU07 firmware 1126 o Samsung 830, 840, and 850 all firmwares 1127 o FCCT M500 all firmwares 1128 1129 Crucial has firmware http://www.crucial.com/usa/en/support-ssd-firmware 1130 with working NCQ TRIM. For Micron branded drives, see your sales rep for 1131 updated firmware. Black listed drives will work correctly because these 1132 drives work correctly so long as no NCQ TRIMs are sent to them. Given 1133 this list is the same as found in Linux, it's believed there are no 1134 other rogues in the market place. All other models from the above 1135 vendors work. 1136 1137 To be safe, if you are at all concerned, you can quirk each of your 1138 drives to prevent NCQ from being sent by setting: 1139 kern.cam.ada.X.quirks="0x2" 1140 in loader.conf. If the drive requires the 4k sector quirk, set the 1141 quirks entry to 0x3. 1142 114320160330: 1144 The FAST_DEPEND build option has been removed and its functionality is 1145 now the one true way. The old mkdep(1) style of 'make depend' has 1146 been removed. See 20160311 for further details. 1147 114820160317: 1149 Resource range types have grown from unsigned long to uintmax_t. All 1150 drivers, and anything using libdevinfo, need to be recompiled. 1151 115220160311: 1153 WITH_FAST_DEPEND is now enabled by default for in-tree and out-of-tree 1154 builds. It no longer runs mkdep(1) during 'make depend', and the 1155 'make depend' stage can safely be skipped now as it is auto ran 1156 when building 'make all' and will generate all SRCS and DPSRCS before 1157 building anything else. Dependencies are gathered at compile time with 1158 -MF flags kept in separate .depend files per object file. Users should 1159 run 'make cleandepend' once if using -DNO_CLEAN to clean out older 1160 stale .depend files. 1161 116220160306: 1163 On amd64, clang 3.8.0 can now insert sections of type AMD64_UNWIND into 1164 kernel modules. Therefore, if you load any kernel modules at boot time, 1165 please install the boot loaders after you install the kernel, but before 1166 rebooting, e.g.: 1167 1168 make buildworld 1169 make buildkernel KERNCONF=YOUR_KERNEL_HERE 1170 make installkernel KERNCONF=YOUR_KERNEL_HERE 1171 make -C sys/boot install 1172 <reboot in single user> 1173 1174 Then follow the usual steps, described in the General Notes section, 1175 below. 1176 117720160305: 1178 Clang, llvm, lldb and compiler-rt have been upgraded to 3.8.0. Please 1179 see the 20141231 entry below for information about prerequisites and 1180 upgrading, if you are not already using clang 3.5.0 or higher. 1181 118220160301: 1183 The AIO subsystem is now a standard part of the kernel. The 1184 VFS_AIO kernel option and aio.ko kernel module have been removed. 1185 Due to stability concerns, asynchronous I/O requests are only 1186 permitted on sockets and raw disks by default. To enable 1187 asynchronous I/O requests on all file types, set the 1188 vfs.aio.enable_unsafe sysctl to a non-zero value. 1189 119020160226: 1191 The ELF object manipulation tool objcopy is now provided by the 1192 ELF Tool Chain project rather than by GNU binutils. It should be a 1193 drop-in replacement, with the addition of arm64 support. The 1194 (temporary) src.conf knob WITHOUT_ELFCOPY_AS_OBJCOPY knob may be set 1195 to obtain the GNU version if necessary. 1196 119720160129: 1198 Building ZFS pools on top of zvols is prohibited by default. That 1199 feature has never worked safely; it's always been prone to deadlocks. 1200 Using a zvol as the backing store for a VM guest's virtual disk will 1201 still work, even if the guest is using ZFS. Legacy behavior can be 1202 restored by setting vfs.zfs.vol.recursive=1. 1203 120420160119: 1205 The NONE and HPN patches has been removed from OpenSSH. They are 1206 still available in the security/openssh-portable port. 1207 120820160113: 1209 With the addition of ypldap(8), a new _ypldap user is now required 1210 during installworld. "mergemaster -p" can be used to add the user 1211 prior to installworld, as documented in the handbook. 1212 121320151216: 1214 The tftp loader (pxeboot) now uses the option root-path directive. As a 1215 consequence it no longer looks for a pxeboot.4th file on the tftp 1216 server. Instead it uses the regular /boot infrastructure as with the 1217 other loaders. 1218 121920151211: 1220 The code to start recording plug and play data into the modules has 1221 been committed. While the old tools will properly build a new kernel, 1222 a number of warnings about "unknown metadata record 4" will be produced 1223 for an older kldxref. To avoid such warnings, make sure to rebuild 1224 the kernel toolchain (or world). Make sure that you have r292078 or 1225 later when trying to build 292077 or later before rebuilding. 1226 122720151207: 1228 Debug data files are now built by default with 'make buildworld' and 1229 installed with 'make installworld'. This facilitates debugging but 1230 requires more disk space both during the build and for the installed 1231 world. Debug files may be disabled by setting WITHOUT_DEBUG_FILES=yes 1232 in src.conf(5). 1233 123420151130: 1235 r291527 changed the internal interface between the nfsd.ko and 1236 nfscommon.ko modules. As such, they must both be upgraded to-gether. 1237 __FreeBSD_version has been bumped because of this. 1238 123920151108: 1240 Add support for unicode collation strings leads to a change of 1241 order of files listed by ls(1) for example. To get back to the old 1242 behaviour, set LC_COLLATE environment variable to "C". 1243 1244 Databases administrators will need to reindex their databases given 1245 collation results will be different. 1246 1247 Due to a bug in install(1) it is recommended to remove the ancient 1248 locales before running make installworld. 1249 1250 rm -rf /usr/share/locale/* 1251 125220151030: 1253 The OpenSSL has been upgraded to 1.0.2d. Any binaries requiring 1254 libcrypto.so.7 or libssl.so.7 must be recompiled. 1255 125620151020: 1257 Qlogic 24xx/25xx firmware images were updated from 5.5.0 to 7.3.0. 1258 Kernel modules isp_2400_multi and isp_2500_multi were removed and 1259 should be replaced with isp_2400 and isp_2500 modules respectively. 1260 126120151017: 1262 The build previously allowed using 'make -n' to not recurse into 1263 sub-directories while showing what commands would be executed, and 1264 'make -n -n' to recursively show commands. Now 'make -n' will recurse 1265 and 'make -N' will not. 1266 126720151012: 1268 If you specify SENDMAIL_MC or SENDMAIL_CF in make.conf, mergemaster 1269 and etcupdate will now use this file. A custom sendmail.cf is now 1270 updated via this mechanism rather than via installworld. If you had 1271 excluded sendmail.cf in mergemaster.rc or etcupdate.conf, you may 1272 want to remove the exclusion or change it to "always install". 1273 /etc/mail/sendmail.cf is now managed the same way regardless of 1274 whether SENDMAIL_MC/SENDMAIL_CF is used. If you are not using 1275 SENDMAIL_MC/SENDMAIL_CF there should be no change in behavior. 1276 127720151011: 1278 Compatibility shims for legacy ATA device names have been removed. 1279 It includes ATA_STATIC_ID kernel option, kern.cam.ada.legacy_aliases 1280 and kern.geom.raid.legacy_aliases loader tunables, kern.devalias.* 1281 environment variables, /dev/ad* and /dev/ar* symbolic links. 1282 128320151006: 1284 Clang, llvm, lldb, compiler-rt and libc++ have been upgraded to 3.7.0. 1285 Please see the 20141231 entry below for information about prerequisites 1286 and upgrading, if you are not already using clang 3.5.0 or higher. 1287 128820150924: 1289 Kernel debug files have been moved to /usr/lib/debug/boot/kernel/, 1290 and renamed from .symbols to .debug. This reduces the size requirements 1291 on the boot partition or file system and provides consistency with 1292 userland debug files. 1293 1294 When using the supported kernel installation method the 1295 /usr/lib/debug/boot/kernel directory will be renamed (to kernel.old) 1296 as is done with /boot/kernel. 1297 1298 Developers wishing to maintain the historical behavior of installing 1299 debug files in /boot/kernel/ can set KERN_DEBUGDIR="" in src.conf(5). 1300 130120150827: 1302 The wireless drivers had undergone changes that remove the 'parent 1303 interface' from the ifconfig -l output. The rc.d network scripts 1304 used to check presence of a parent interface in the list, so old 1305 scripts would fail to start wireless networking. Thus, etcupdate(3) 1306 or mergemaster(8) run is required after kernel update, to update your 1307 rc.d scripts in /etc. 1308 130920150827: 1310 pf no longer supports 'scrub fragment crop' or 'scrub fragment drop-ovl' 1311 These configurations are now automatically interpreted as 1312 'scrub fragment reassemble'. 1313 131420150817: 1315 Kernel-loadable modules for the random(4) device are back. To use 1316 them, the kernel must have 1317 1318 device random 1319 options RANDOM_LOADABLE 1320 1321 kldload(8) can then be used to load random_fortuna.ko 1322 or random_yarrow.ko. Please note that due to the indirect 1323 function calls that the loadable modules need to provide, 1324 the build-in variants will be slightly more efficient. 1325 1326 The random(4) kernel option RANDOM_DUMMY has been retired due to 1327 unpopularity. It was not all that useful anyway. 1328 132920150813: 1330 The WITHOUT_ELFTOOLCHAIN_TOOLS src.conf(5) knob has been retired. 1331 Control over building the ELF Tool Chain tools is now provided by 1332 the WITHOUT_TOOLCHAIN knob. 1333 133420150810: 1335 The polarity of Pulse Per Second (PPS) capture events with the 1336 uart(4) driver has been corrected. Prior to this change the PPS 1337 "assert" event corresponded to the trailing edge of a positive PPS 1338 pulse and the "clear" event was the leading edge of the next pulse. 1339 1340 As the width of a PPS pulse in a typical GPS receiver is on the 1341 order of 1 millisecond, most users will not notice any significant 1342 difference with this change. 1343 1344 Anyone who has compensated for the historical polarity reversal by 1345 configuring a negative offset equal to the pulse width will need to 1346 remove that workaround. 1347 134820150809: 1349 The default group assigned to /dev/dri entries has been changed 1350 from 'wheel' to 'video' with the id of '44'. If you want to have 1351 access to the dri devices please add yourself to the video group 1352 with: 1353 1354 # pw groupmod video -m $USER 1355 135620150806: 1357 The menu.rc and loader.rc files will now be replaced during 1358 upgrades. Please migrate local changes to menu.rc.local and 1359 loader.rc.local instead. 1360 136120150805: 1362 GNU Binutils versions of addr2line, c++filt, nm, readelf, size, 1363 strings and strip have been removed. The src.conf(5) knob 1364 WITHOUT_ELFTOOLCHAIN_TOOLS no longer provides the binutils tools. 1365 136620150728: 1367 As ZFS requires more kernel stack pages than is the default on some 1368 architectures e.g. i386, it now warns if KSTACK_PAGES is less than 1369 ZFS_MIN_KSTACK_PAGES (which is 4 at the time of writing). 1370 1371 Please consider using 'options KSTACK_PAGES=X' where X is greater 1372 than or equal to ZFS_MIN_KSTACK_PAGES i.e. 4 in such configurations. 1373 137420150706: 1375 sendmail has been updated to 8.15.2. Starting with FreeBSD 11.0 1376 and sendmail 8.15, sendmail uses uncompressed IPv6 addresses by 1377 default, i.e., they will not contain "::". For example, instead 1378 of ::1, it will be 0:0:0:0:0:0:0:1. This permits a zero subnet 1379 to have a more specific match, such as different map entries for 1380 IPv6:0:0 vs IPv6:0. This change requires that configuration 1381 data (including maps, files, classes, custom ruleset, etc.) must 1382 use the same format, so make certain such configuration data is 1383 upgrading. As a very simple check search for patterns like 1384 'IPv6:[0-9a-fA-F:]*::' and 'IPv6::'. To return to the old 1385 behavior, set the m4 option confUSE_COMPRESSED_IPV6_ADDRESSES or 1386 the cf option UseCompressedIPv6Addresses. 1387 138820150630: 1389 The default kernel entropy-processing algorithm is now 1390 Fortuna, replacing Yarrow. 1391 1392 Assuming you have 'device random' in your kernel config 1393 file, the configurations allow a kernel option to override 1394 this default. You may choose *ONE* of: 1395 1396 options RANDOM_YARROW # Legacy /dev/random algorithm. 1397 options RANDOM_DUMMY # Blocking-only driver. 1398 1399 If you have neither, you get Fortuna. For most people, 1400 read no further, Fortuna will give a /dev/random that works 1401 like it always used to, and the difference will be irrelevant. 1402 1403 If you remove 'device random', you get *NO* kernel-processed 1404 entropy at all. This may be acceptable to folks building 1405 embedded systems, but has complications. Carry on reading, 1406 and it is assumed you know what you need. 1407 1408 *PLEASE* read random(4) and random(9) if you are in the 1409 habit of tweaking kernel configs, and/or if you are a member 1410 of the embedded community, wanting specific and not-usual 1411 behaviour from your security subsystems. 1412 1413 NOTE!! If you use RANDOM_DUMMY and/or have no 'device 1414 random', you will NOT have a functioning /dev/random, and 1415 many cryptographic features will not work, including SSH. 1416 You may also find strange behaviour from the random(3) set 1417 of library functions, in particular sranddev(3), srandomdev(3) 1418 and arc4random(3). The reason for this is that the KERN_ARND 1419 sysctl only returns entropy if it thinks it has some to 1420 share, and with RANDOM_DUMMY or no 'device random' this 1421 will never happen. 1422 142320150623: 1424 An additional fix for the issue described in the 20150614 sendmail 1425 entry below has been committed in revision 284717. 1426 142720150616: 1428 FreeBSD's old make (fmake) has been removed from the system. It is 1429 available as the devel/fmake port or via pkg install fmake. 1430 143120150615: 1432 The fix for the issue described in the 20150614 sendmail entry 1433 below has been committed in revision 284436. The work 1434 around described in that entry is no longer needed unless the 1435 default setting is overridden by a confDH_PARAMETERS configuration 1436 setting of '5' or pointing to a 512 bit DH parameter file. 1437 143820150614: 1439 ALLOW_DEPRECATED_ATF_TOOLS/ATFFILE support has been removed from 1440 atf.test.mk (included from bsd.test.mk). Please upgrade devel/atf 1441 and devel/kyua to version 0.20+ and adjust any calling code to work 1442 with Kyuafile and kyua. 1443 144420150614: 1445 The import of openssl to address the FreeBSD-SA-15:10.openssl 1446 security advisory includes a change which rejects handshakes 1447 with DH parameters below 768 bits. sendmail releases prior 1448 to 8.15.2 (not yet released), defaulted to a 512 bit 1449 DH parameter setting for client connections. To work around 1450 this interoperability, sendmail can be configured to use a 1451 2048 bit DH parameter by: 1452 1453 1. Edit /etc/mail/`hostname`.mc 1454 2. If a setting for confDH_PARAMETERS does not exist or 1455 exists and is set to a string beginning with '5', 1456 replace it with '2'. 1457 3. If a setting for confDH_PARAMETERS exists and is set to 1458 a file path, create a new file with: 1459 openssl dhparam -out /path/to/file 2048 1460 4. Rebuild the .cf file: 1461 cd /etc/mail/; make; make install 1462 5. Restart sendmail: 1463 cd /etc/mail/; make restart 1464 1465 A sendmail patch is coming, at which time this file will be 1466 updated. 1467 146820150604: 1469 Generation of legacy formatted entries have been disabled by default 1470 in pwd_mkdb(8), as all base system consumers of the legacy formatted 1471 entries were converted to use the new format by default when the new, 1472 machine independent format have been added and supported since FreeBSD 1473 5.x. 1474 1475 Please see the pwd_mkdb(8) manual page for further details. 1476 147720150525: 1478 Clang and llvm have been upgraded to 3.6.1 release. Please see the 1479 20141231 entry below for information about prerequisites and upgrading, 1480 if you are not already using 3.5.0 or higher. 1481 148220150521: 1483 TI platform code switched to using vendor DTS files and this update 1484 may break existing systems running on Beaglebone, Beaglebone Black, 1485 and Pandaboard: 1486 1487 - dtb files should be regenerated/reinstalled. Filenames are the 1488 same but content is different now 1489 - GPIO addressing was changed, now each GPIO bank (32 pins per bank) 1490 has its own /dev/gpiocX device, e.g. pin 121 on /dev/gpioc0 in old 1491 addressing scheme is now pin 25 on /dev/gpioc3. 1492 - Pandaboard: /etc/ttys should be updated, serial console device is 1493 now /dev/ttyu2, not /dev/ttyu0 1494 149520150501: 1496 soelim(1) from gnu/usr.bin/groff has been replaced by usr.bin/soelim. 1497 If you need the GNU extension from groff soelim(1), install groff 1498 from package: pkg install groff, or via ports: textproc/groff. 1499 150020150423: 1501 chmod, chflags, chown and chgrp now affect symlinks in -R mode as 1502 defined in symlink(7); previously symlinks were silently ignored. 1503 150420150415: 1505 The const qualifier has been removed from iconv(3) to comply with 1506 POSIX. The ports tree is aware of this from r384038 onwards. 1507 150820150416: 1509 Libraries specified by LIBADD in Makefiles must have a corresponding 1510 DPADD_<lib> variable to ensure correct dependencies. This is now 1511 enforced in src.libnames.mk. 1512 151320150324: 1514 From legacy ata(4) driver was removed support for SATA controllers 1515 supported by more functional drivers ahci(4), siis(4) and mvs(4). 1516 Kernel modules ataahci and ataadaptec were removed completely, 1517 replaced by ahci and mvs modules respectively. 1518 151920150315: 1520 Clang, llvm and lldb have been upgraded to 3.6.0 release. Please see 1521 the 20141231 entry below for information about prerequisites and 1522 upgrading, if you are not already using 3.5.0 or higher. 1523 152420150307: 1525 The 32-bit PowerPC kernel has been changed to a position-independent 1526 executable. This can only be booted with a version of loader(8) 1527 newer than January 31, 2015, so make sure to update both world and 1528 kernel before rebooting. 1529 153020150217: 1531 If you are running a -CURRENT kernel since r273872 (Oct 30th, 2014), 1532 but before r278950, the RNG was not seeded properly. Immediately 1533 upgrade the kernel to r278950 or later and regenerate any keys (e.g. 1534 ssh keys or openssl keys) that were generated w/ a kernel from that 1535 range. This does not affect programs that directly used /dev/random 1536 or /dev/urandom. All userland uses of arc4random(3) are affected. 1537 153820150210: 1539 The autofs(4) ABI was changed in order to restore binary compatibility 1540 with 10.1-RELEASE. The automountd(8) daemon needs to be rebuilt to work 1541 with the new kernel. 1542 154320150131: 1544 The powerpc64 kernel has been changed to a position-independent 1545 executable. This can only be booted with a new version of loader(8), 1546 so make sure to update both world and kernel before rebooting. 1547 154820150118: 1549 Clang and llvm have been upgraded to 3.5.1 release. This is a bugfix 1550 only release, no new features have been added. Please see the 20141231 1551 entry below for information about prerequisites and upgrading, if you 1552 are not already using 3.5.0. 1553 155420150107: 1555 ELF tools addr2line, elfcopy (strip), nm, size, and strings are now 1556 taken from the ELF Tool Chain project rather than GNU binutils. They 1557 should be drop-in replacements, with the addition of arm64 support. 1558 The WITHOUT_ELFTOOLCHAIN_TOOLS= knob may be used to obtain the 1559 binutils tools, if necessary. See 20150805 for updated information. 1560 156120150105: 1562 The default Unbound configuration now enables remote control 1563 using a local socket. Users who have already enabled the 1564 local_unbound service should regenerate their configuration 1565 by running "service local_unbound setup" as root. 1566 156720150102: 1568 The GNU texinfo and GNU info pages have been removed. 1569 To be able to view GNU info pages please install texinfo from ports. 1570 157120141231: 1572 Clang, llvm and lldb have been upgraded to 3.5.0 release. 1573 1574 As of this release, a prerequisite for building clang, llvm and lldb is 1575 a C++11 capable compiler and C++11 standard library. This means that to 1576 be able to successfully build the cross-tools stage of buildworld, with 1577 clang as the bootstrap compiler, your system compiler or cross compiler 1578 should either be clang 3.3 or later, or gcc 4.8 or later, and your 1579 system C++ library should be libc++, or libdstdc++ from gcc 4.8 or 1580 later. 1581 1582 On any standard FreeBSD 10.x or 11.x installation, where clang and 1583 libc++ are on by default (that is, on x86 or arm), this should work out 1584 of the box. 1585 1586 On 9.x installations where clang is enabled by default, e.g. on x86 and 1587 powerpc, libc++ will not be enabled by default, so libc++ should be 1588 built (with clang) and installed first. If both clang and libc++ are 1589 missing, build clang first, then use it to build libc++. 1590 1591 On 8.x and earlier installations, upgrade to 9.x first, and then follow 1592 the instructions for 9.x above. 1593 1594 Sparc64 and mips users are unaffected, as they still use gcc 4.2.1 by 1595 default, and do not build clang. 1596 1597 Many embedded systems are resource constrained, and will not be able to 1598 build clang in a reasonable time, or in some cases at all. In those 1599 cases, cross building bootable systems on amd64 is a workaround. 1600 1601 This new version of clang introduces a number of new warnings, of which 1602 the following are most likely to appear: 1603 1604 -Wabsolute-value 1605 1606 This warns in two cases, for both C and C++: 1607 * When the code is trying to take the absolute value of an unsigned 1608 quantity, which is effectively a no-op, and almost never what was 1609 intended. The code should be fixed, if at all possible. If you are 1610 sure that the unsigned quantity can be safely cast to signed, without 1611 loss of information or undefined behavior, you can add an explicit 1612 cast, or disable the warning. 1613 1614 * When the code is trying to take an absolute value, but the called 1615 abs() variant is for the wrong type, which can lead to truncation. 1616 If you want to disable the warning instead of fixing the code, please 1617 make sure that truncation will not occur, or it might lead to unwanted 1618 side-effects. 1619 1620 -Wtautological-undefined-compare and 1621 -Wundefined-bool-conversion 1622 1623 These warn when C++ code is trying to compare 'this' against NULL, while 1624 'this' should never be NULL in well-defined C++ code. However, there is 1625 some legacy (pre C++11) code out there, which actively abuses this 1626 feature, which was less strictly defined in previous C++ versions. 1627 1628 Squid and openjdk do this, for example. The warning can be turned off 1629 for C++98 and earlier, but compiling the code in C++11 mode might result 1630 in unexpected behavior; for example, the parts of the program that are 1631 unreachable could be optimized away. 1632 163320141222: 1634 The old NFS client and server (kernel options NFSCLIENT, NFSSERVER) 1635 kernel sources have been removed. The .h files remain, since some 1636 utilities include them. This will need to be fixed later. 1637 If "mount -t oldnfs ..." is attempted, it will fail. 1638 If the "-o" option on mountd(8), nfsd(8) or nfsstat(1) is used, 1639 the utilities will report errors. 1640 164120141121: 1642 The handling of LOCAL_LIB_DIRS has been altered to skip addition of 1643 directories to top level SUBDIR variable when their parent 1644 directory is included in LOCAL_DIRS. Users with build systems with 1645 such hierarchies and without SUBDIR entries in the parent 1646 directory Makefiles should add them or add the directories to 1647 LOCAL_DIRS. 1648 164920141109: 1650 faith(4) and faithd(8) have been removed from the base system. Faith 1651 has been obsolete for a very long time. 1652 165320141104: 1654 vt(4), the new console driver, is enabled by default. It brings 1655 support for Unicode and double-width characters, as well as 1656 support for UEFI and integration with the KMS kernel video 1657 drivers. 1658 1659 You may need to update your console settings in /etc/rc.conf, 1660 most probably the keymap. During boot, /etc/rc.d/syscons will 1661 indicate what you need to do. 1662 1663 vt(4) still has issues and lacks some features compared to 1664 syscons(4). See the wiki for up-to-date information: 1665 https://wiki.freebsd.org/Newcons 1666 1667 If you want to keep using syscons(4), you can do so by adding 1668 the following line to /boot/loader.conf: 1669 kern.vty=sc 1670 167120141102: 1672 pjdfstest has been integrated into kyua as an opt-in test suite. 1673 Please see share/doc/pjdfstest/README for more details on how to 1674 execute it. 1675 167620141009: 1677 gperf has been removed from the base system for architectures 1678 that use clang. Ports that require gperf will obtain it from the 1679 devel/gperf port. 1680 168120140923: 1682 pjdfstest has been moved from tools/regression/pjdfstest to 1683 contrib/pjdfstest . 1684 168520140922: 1686 At svn r271982, The default linux compat kernel ABI has been adjusted 1687 to 2.6.18 in support of the linux-c6 compat ports infrastructure 1688 update. If you wish to continue using the linux-f10 compat ports, 1689 add compat.linux.osrelease=2.6.16 to your local sysctl.conf. Users are 1690 encouraged to update their linux-compat packages to linux-c6 during 1691 their next update cycle. 1692 169320140729: 1694 The ofwfb driver, used to provide a graphics console on PowerPC when 1695 using vt(4), no longer allows mmap() of all physical memory. This 1696 will prevent Xorg on PowerPC with some ATI graphics cards from 1697 initializing properly unless x11-servers/xorg-server is updated to 1698 1.12.4_8 or newer. 1699 170020140723: 1701 The xdev targets have been converted to using TARGET and 1702 TARGET_ARCH instead of XDEV and XDEV_ARCH. 1703 170420140719: 1705 The default unbound configuration has been modified to address 1706 issues with reverse lookups on networks that use private 1707 address ranges. If you use the local_unbound service, run 1708 "service local_unbound setup" as root to regenerate your 1709 configuration, then "service local_unbound reload" to load the 1710 new configuration. 1711 171220140709: 1713 The GNU texinfo and GNU info pages are not built and installed 1714 anymore, WITH_INFO knob has been added to allow to built and install 1715 them again. 1716 UPDATE: see 20150102 entry on texinfo's removal 1717 171820140708: 1719 The GNU readline library is now an INTERNALLIB - that is, it is 1720 statically linked into consumers (GDB and variants) in the base 1721 system, and the shared library is no longer installed. The 1722 devel/readline port is available for third party software that 1723 requires readline. 1724 172520140702: 1726 The Itanium architecture (ia64) has been removed from the list of 1727 known architectures. This is the first step in the removal of the 1728 architecture. 1729 173020140701: 1731 Commit r268115 has added NFSv4.1 server support, merged from 1732 projects/nfsv4.1-server. Since this includes changes to the 1733 internal interfaces between the NFS related modules, a full 1734 build of the kernel and modules will be necessary. 1735 __FreeBSD_version has been bumped. 1736 173720140629: 1738 The WITHOUT_VT_SUPPORT kernel config knob has been renamed 1739 WITHOUT_VT. (The other _SUPPORT knobs have a consistent meaning 1740 which differs from the behaviour controlled by this knob.) 1741 174220140619: 1743 Maximal length of the serial number in CTL was increased from 16 to 1744 64 chars, that breaks ABI. All CTL-related tools, such as ctladm 1745 and ctld, need to be rebuilt to work with a new kernel. 1746 174720140606: 1748 The libatf-c and libatf-c++ major versions were downgraded to 0 and 1749 1 respectively to match the upstream numbers. They were out of 1750 sync because, when they were originally added to FreeBSD, the 1751 upstream versions were not respected. These libraries are private 1752 and not yet built by default, so renumbering them should be a 1753 non-issue. However, unclean source trees will yield broken test 1754 programs once the operator executes "make delete-old-libs" after a 1755 "make installworld". 1756 1757 Additionally, the atf-sh binary was made private by moving it into 1758 /usr/libexec/. Already-built shell test programs will keep the 1759 path to the old binary so they will break after "make delete-old" 1760 is run. 1761 1762 If you are using WITH_TESTS=yes (not the default), wipe the object 1763 tree and rebuild from scratch to prevent spurious test failures. 1764 This is only needed once: the misnumbered libraries and misplaced 1765 binaries have been added to OptionalObsoleteFiles.inc so they will 1766 be removed during a clean upgrade. 1767 176820140512: 1769 Clang and llvm have been upgraded to 3.4.1 release. 1770 177120140508: 1772 We bogusly installed src.opts.mk in /usr/share/mk. This file should 1773 be removed to avoid issues in the future (and has been added to 1774 ObsoleteFiles.inc). 1775 177620140505: 1777 /etc/src.conf now affects only builds of the FreeBSD src tree. In the 1778 past, it affected all builds that used the bsd.*.mk files. The old 1779 behavior was a bug, but people may have relied upon it. To get this 1780 behavior back, you can .include /etc/src.conf from /etc/make.conf 1781 (which is still global and isn't changed). This also changes the 1782 behavior of incremental builds inside the tree of individual 1783 directories. Set MAKESYSPATH to ".../share/mk" to do that. 1784 Although this has survived make universe and some upgrade scenarios, 1785 other upgrade scenarios may have broken. At least one form of 1786 temporary breakage was fixed with MAKESYSPATH settings for buildworld 1787 as well... In cases where MAKESYSPATH isn't working with this 1788 setting, you'll need to set it to the full path to your tree. 1789 1790 One side effect of all this cleaning up is that bsd.compiler.mk 1791 is no longer implicitly included by bsd.own.mk. If you wish to 1792 use COMPILER_TYPE, you must now explicitly include bsd.compiler.mk 1793 as well. 1794 179520140430: 1796 The lindev device has been removed since /dev/full has been made a 1797 standard device. __FreeBSD_version has been bumped. 1798 179920140424: 1800 The knob WITHOUT_VI was added to the base system, which controls 1801 building ex(1), vi(1), etc. Older releases of FreeBSD required ex(1) 1802 in order to reorder files share/termcap and didn't build ex(1) as a 1803 build tool, so building/installing with WITH_VI is highly advised for 1804 build hosts for older releases. 1805 1806 This issue has been fixed in stable/9 and stable/10 in r277022 and 1807 r276991, respectively. 1808 180920140418: 1810 The YES_HESIOD knob has been removed. It has been obsolete for 1811 a decade. Please move to using WITH_HESIOD instead or your builds 1812 will silently lack HESIOD. 1813 181420140405: 1815 The uart(4) driver has been changed with respect to its handling 1816 of the low-level console. Previously the uart(4) driver prevented 1817 any process from changing the baudrate or the CLOCAL and HUPCL 1818 control flags. By removing the restrictions, operators can make 1819 changes to the serial console port without having to reboot. 1820 However, when getty(8) is started on the serial device that is 1821 associated with the low-level console, a misconfigured terminal 1822 line in /etc/ttys will now have a real impact. 1823 Before upgrading the kernel, make sure that /etc/ttys has the 1824 serial console device configured as 3wire without baudrate to 1825 preserve the previous behaviour. E.g: 1826 ttyu0 "/usr/libexec/getty 3wire" vt100 on secure 1827 182820140306: 1829 Support for libwrap (TCP wrappers) in rpcbind was disabled by default 1830 to improve performance. To re-enable it, if needed, run rpcbind 1831 with command line option -W. 1832 183320140226: 1834 Switched back to the GPL dtc compiler due to updates in the upstream 1835 dts files not being supported by the BSDL dtc compiler. You will need 1836 to rebuild your kernel toolchain to pick up the new compiler. Core dumps 1837 may result while building dtb files during a kernel build if you fail 1838 to do so. Set WITHOUT_GPL_DTC if you require the BSDL compiler. 1839 184020140216: 1841 Clang and llvm have been upgraded to 3.4 release. 1842 184320140216: 1844 The nve(4) driver has been removed. Please use the nfe(4) driver 1845 for NVIDIA nForce MCP Ethernet adapters instead. 1846 184720140212: 1848 An ABI incompatibility crept into the libc++ 3.4 import in r261283. 1849 This could cause certain C++ applications using shared libraries built 1850 against the previous version of libc++ to crash. The incompatibility 1851 has now been fixed, but any C++ applications or shared libraries built 1852 between r261283 and r261801 should be recompiled. 1853 185420140204: 1855 OpenSSH will now ignore errors caused by kernel lacking of Capsicum 1856 capability mode support. Please note that enabling the feature in 1857 kernel is still highly recommended. 1858 185920140131: 1860 OpenSSH is now built with sandbox support, and will use sandbox as 1861 the default privilege separation method. This requires Capsicum 1862 capability mode support in kernel. 1863 186420140128: 1865 The libelf and libdwarf libraries have been updated to newer 1866 versions from upstream. Shared library version numbers for 1867 these two libraries were bumped. Any ports or binaries 1868 requiring these two libraries should be recompiled. 1869 __FreeBSD_version is bumped to 1100006. 1870 187120140110: 1872 If a Makefile in a tests/ directory was auto-generating a Kyuafile 1873 instead of providing an explicit one, this would prevent such 1874 Makefile from providing its own Kyuafile in the future during 1875 NO_CLEAN builds. This has been fixed in the Makefiles but manual 1876 intervention is needed to clean an objdir if you use NO_CLEAN: 1877 # find /usr/obj -name Kyuafile | xargs rm -f 1878 187920131213: 1880 The behavior of gss_pseudo_random() for the krb5 mechanism 1881 has changed, for applications requesting a longer random string 1882 than produced by the underlying enctype's pseudo-random() function. 1883 In particular, the random string produced from a session key of 1884 enctype aes256-cts-hmac-sha1-96 or aes256-cts-hmac-sha1-96 will 1885 be different at the 17th octet and later, after this change. 1886 The counter used in the PRF+ construction is now encoded as a 1887 big-endian integer in accordance with RFC 4402. 1888 __FreeBSD_version is bumped to 1100004. 1889 189020131108: 1891 The WITHOUT_ATF build knob has been removed and its functionality 1892 has been subsumed into the more generic WITHOUT_TESTS. If you were 1893 using the former to disable the build of the ATF libraries, you 1894 should change your settings to use the latter. 1895 189620131025: 1897 The default version of mtree is nmtree which is obtained from 1898 NetBSD. The output is generally the same, but may vary 1899 slightly. If you found you need identical output adding 1900 "-F freebsd9" to the command line should do the trick. For the 1901 time being, the old mtree is available as fmtree. 1902 190320131014: 1904 libbsdyml has been renamed to libyaml and moved to /usr/lib/private. 1905 This will break ports-mgmt/pkg. Rebuild the port, or upgrade to pkg 1906 1.1.4_8 and verify bsdyml not linked in, before running "make 1907 delete-old-libs": 1908 # make -C /usr/ports/ports-mgmt/pkg build deinstall install clean 1909 or 1910 # pkg install pkg; ldd /usr/local/sbin/pkg | grep bsdyml 1911 191220131010: 1913 The stable/10 branch has been created in subversion from head 1914 revision r256279. 1915 1916COMMON ITEMS: 1917 1918 General Notes 1919 ------------- 1920 Avoid using make -j when upgrading. While generally safe, there are 1921 sometimes problems using -j to upgrade. If your upgrade fails with 1922 -j, please try again without -j. From time to time in the past there 1923 have been problems using -j with buildworld and/or installworld. This 1924 is especially true when upgrading between "distant" versions (eg one 1925 that cross a major release boundary or several minor releases, or when 1926 several months have passed on the -current branch). 1927 1928 Sometimes, obscure build problems are the result of environment 1929 poisoning. This can happen because the make utility reads its 1930 environment when searching for values for global variables. To run 1931 your build attempts in an "environmental clean room", prefix all make 1932 commands with 'env -i '. See the env(1) manual page for more details. 1933 1934 When upgrading from one major version to another it is generally best to 1935 upgrade to the latest code in the currently installed branch first, then 1936 do an upgrade to the new branch. This is the best-tested upgrade path, 1937 and has the highest probability of being successful. Please try this 1938 approach if you encounter problems with a major version upgrade. Since 1939 the stable 4.x branch point, one has generally been able to upgrade from 1940 anywhere in the most recent stable branch to head / current (or even the 1941 last couple of stable branches). See the top of this file when there's 1942 an exception. 1943 1944 When upgrading a live system, having a root shell around before 1945 installing anything can help undo problems. Not having a root shell 1946 around can lead to problems if pam has changed too much from your 1947 starting point to allow continued authentication after the upgrade. 1948 1949 This file should be read as a log of events. When a later event changes 1950 information of a prior event, the prior event should not be deleted. 1951 Instead, a pointer to the entry with the new information should be 1952 placed in the old entry. Readers of this file should also sanity check 1953 older entries before relying on them blindly. Authors of new entries 1954 should write them with this in mind. 1955 1956 ZFS notes 1957 --------- 1958 When upgrading the boot ZFS pool to a new version, always follow 1959 these two steps: 1960 1961 1.) recompile and reinstall the ZFS boot loader and boot block 1962 (this is part of "make buildworld" and "make installworld") 1963 1964 2.) update the ZFS boot block on your boot drive 1965 1966 The following example updates the ZFS boot block on the first 1967 partition (freebsd-boot) of a GPT partitioned drive ada0: 1968 "gpart bootcode -p /boot/gptzfsboot -i 1 ada0" 1969 1970 Non-boot pools do not need these updates. 1971 1972 To build a kernel 1973 ----------------- 1974 If you are updating from a prior version of FreeBSD (even one just 1975 a few days old), you should follow this procedure. It is the most 1976 failsafe as it uses a /usr/obj tree with a fresh mini-buildworld, 1977 1978 make kernel-toolchain 1979 make -DALWAYS_CHECK_MAKE buildkernel KERNCONF=YOUR_KERNEL_HERE 1980 make -DALWAYS_CHECK_MAKE installkernel KERNCONF=YOUR_KERNEL_HERE 1981 1982 To test a kernel once 1983 --------------------- 1984 If you just want to boot a kernel once (because you are not sure 1985 if it works, or if you want to boot a known bad kernel to provide 1986 debugging information) run 1987 make installkernel KERNCONF=YOUR_KERNEL_HERE KODIR=/boot/testkernel 1988 nextboot -k testkernel 1989 1990 To rebuild everything and install it on the current system. 1991 ----------------------------------------------------------- 1992 # Note: sometimes if you are running current you gotta do more than 1993 # is listed here if you are upgrading from a really old current. 1994 1995 <make sure you have good level 0 dumps> 1996 make buildworld 1997 make buildkernel KERNCONF=YOUR_KERNEL_HERE 1998 make installkernel KERNCONF=YOUR_KERNEL_HERE 1999 [1] 2000 <reboot in single user> [3] 2001 mergemaster -Fp [5] 2002 make installworld 2003 mergemaster -Fi [4] 2004 make delete-old [6] 2005 <reboot> 2006 2007 To cross-install current onto a separate partition 2008 -------------------------------------------------- 2009 # In this approach we use a separate partition to hold 2010 # current's root, 'usr', and 'var' directories. A partition 2011 # holding "/", "/usr" and "/var" should be about 2GB in 2012 # size. 2013 2014 <make sure you have good level 0 dumps> 2015 <boot into -stable> 2016 make buildworld 2017 make buildkernel KERNCONF=YOUR_KERNEL_HERE 2018 <maybe newfs current's root partition> 2019 <mount current's root partition on directory ${CURRENT_ROOT}> 2020 make installworld DESTDIR=${CURRENT_ROOT} -DDB_FROM_SRC 2021 make distribution DESTDIR=${CURRENT_ROOT} # if newfs'd 2022 make installkernel KERNCONF=YOUR_KERNEL_HERE DESTDIR=${CURRENT_ROOT} 2023 cp /etc/fstab ${CURRENT_ROOT}/etc/fstab # if newfs'd 2024 <edit ${CURRENT_ROOT}/etc/fstab to mount "/" from the correct partition> 2025 <reboot into current> 2026 <do a "native" rebuild/install as described in the previous section> 2027 <maybe install compatibility libraries from ports/misc/compat*> 2028 <reboot> 2029 2030 2031 To upgrade in-place from stable to current 2032 ---------------------------------------------- 2033 <make sure you have good level 0 dumps> 2034 make buildworld [9] 2035 make buildkernel KERNCONF=YOUR_KERNEL_HERE [8] 2036 make installkernel KERNCONF=YOUR_KERNEL_HERE 2037 [1] 2038 <reboot in single user> [3] 2039 mergemaster -Fp [5] 2040 make installworld 2041 mergemaster -Fi [4] 2042 make delete-old [6] 2043 <reboot> 2044 2045 Make sure that you've read the UPDATING file to understand the 2046 tweaks to various things you need. At this point in the life 2047 cycle of current, things change often and you are on your own 2048 to cope. The defaults can also change, so please read ALL of 2049 the UPDATING entries. 2050 2051 Also, if you are tracking -current, you must be subscribed to 2052 [email protected]. Make sure that before you update 2053 your sources that you have read and understood all the recent 2054 messages there. If in doubt, please track -stable which has 2055 much fewer pitfalls. 2056 2057 [1] If you have third party modules, such as vmware, you 2058 should disable them at this point so they don't crash your 2059 system on reboot. 2060 2061 [3] From the bootblocks, boot -s, and then do 2062 fsck -p 2063 mount -u / 2064 mount -a 2065 cd src 2066 adjkerntz -i # if CMOS is wall time 2067 Also, when doing a major release upgrade, it is required that 2068 you boot into single user mode to do the installworld. 2069 2070 [4] Note: This step is non-optional. Failure to do this step 2071 can result in a significant reduction in the functionality of the 2072 system. Attempting to do it by hand is not recommended and those 2073 that pursue this avenue should read this file carefully, as well 2074 as the archives of freebsd-current and freebsd-hackers mailing lists 2075 for potential gotchas. The -U option is also useful to consider. 2076 See mergemaster(8) for more information. 2077 2078 [5] Usually this step is a no-op. However, from time to time 2079 you may need to do this if you get unknown user in the following 2080 step. It never hurts to do it all the time. You may need to 2081 install a new mergemaster (cd src/usr.sbin/mergemaster && make 2082 install) after the buildworld before this step if you last updated 2083 from current before 20130425 or from -stable before 20130430. 2084 2085 [6] This only deletes old files and directories. Old libraries 2086 can be deleted by "make delete-old-libs", but you have to make 2087 sure that no program is using those libraries anymore. 2088 2089 [8] The new kernel must be able to run existing binaries used by 2090 an installworld. When upgrading across major versions, the new 2091 kernel's configuration must include the correct COMPAT_FREEBSD<n> 2092 option for existing binaries (e.g. COMPAT_FREEBSD11 to run 11.x 2093 binaries). Failure to do so may leave you with a system that is 2094 hard to boot to recover. A GENERIC kernel will include suitable 2095 compatibility options to run binaries from older branches. 2096 2097 Make sure that you merge any new devices from GENERIC since the 2098 last time you updated your kernel config file. 2099 2100 [9] If CPUTYPE is defined in your /etc/make.conf, make sure to use the 2101 "?=" instead of the "=" assignment operator, so that buildworld can 2102 override the CPUTYPE if it needs to. 2103 2104 MAKEOBJDIRPREFIX must be defined in an environment variable, and 2105 not on the command line, or in /etc/make.conf. buildworld will 2106 warn if it is improperly defined. 2107FORMAT: 2108 2109This file contains a list, in reverse chronological order, of major 2110breakages in tracking -current. It is not guaranteed to be a complete 2111list of such breakages, and only contains entries since September 23, 2011. 2112If you need to see UPDATING entries from before that date, you will need 2113to fetch an UPDATING file from an older FreeBSD release. 2114 2115Copyright information: 2116 2117Copyright 1998-2009 M.
