1Updating Information for users of FreeBSD-CURRENT. 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://docs.freebsd.org/en/books/handbook/cutting-edge/#makeworld 10 11Items affecting the ports and packages system can be found in 12/usr/ports/UPDATING. Please read that file before updating system packages 13and/or ports. 14 15NOTE TO PEOPLE WHO THINK THAT FreeBSD 15.x IS SLOW: 16 FreeBSD 15.x has many debugging features turned on, in both the kernel 17 and userland. These features attempt to detect incorrect use of 18 system primitives, and encourage loud failure through extra sanity 19 checking and fail stop semantics. They also substantially impact 20 system performance. If you want to do performance measurement, 21 benchmarking, and optimization, you'll want to turn them off. This 22 includes various WITNESS- related kernel options, INVARIANTS, malloc 23 debugging flags in userland, and various verbose features in the 24 kernel. Many developers choose to disable these features on build 25 machines to maximize performance. (To completely disable malloc 26 debugging, define WITH_MALLOC_PRODUCTION in /etc/src.conf and rebuild 27 world, or to merely disable the most expensive debugging functionality 28 at runtime, run "ln -s 'abort:false,junk:false' /etc/malloc.conf".) 29 3020250625: 31 "make delete-old" will now remove the Forth bootloader entirely 32 if the system is built with WITHOUT_FORTH. 33 3420250614: 35 MIT KRB5 (MIT Kerberos5) has been imported into 15-CURRENT. To 36 and install MIT KRB5, add WITH_MITKRB5=yes to /etc/src.conf. This 37 will build and install MIT KRB5 1.21.3. And it will remove Heimdal 38 1.5.2 when delete-old and delete-old-libs are run. To revert back 39 simply buildworld/installworld again with delete-old-libs and 40 delete-old. 41 42 At the moment we only know of a couple of ports that might be 43 affected. Adjusting libmap.conf does not circumvent runtime issues. 44 The few affected ports must be rebuilt. A successful exp-run will be 45 run before MIT KRB5 becomes default. 46 47 Those using the KDC in FreeBSD base may wish to wait. The Heimdal 48 HDB is incompatible with the MIT KRB5 KDC. The migration procedure 49 is a little involved. 50 5120250603: 52 LinuxKPI dma-mapping.h were pulled into the tree from drm-kmod. 53 Bump _FreeBSD_version to 1500045 to be able to detect this change. 54 5520250527: 56 pf changed extension header handling. It now treats AH headers on IPv4 just 57 like AH headers on IPv6 and skips over them, allowing filtering on the inner 58 protocol. 59 6020250527: 61 pf now blocks IPv6 packets with a hop-by-hop or destination options header by 62 default. Such packets can be passed by adding "allow-opts" to the rule. IPv6 63 options are now handled just like their IPv4 counterparts. 64 6520250527: 66 The CAM target layer userland, i.e. ctld(8), ctladm(8) and ctlstat(8), 67 has moved to the new FreeBSD-ctl package. If you use pkgbase and you 68 need the CAM Target Layer, you should install the new package. 69 70 Development-related tools (e.g. ar and nm) have moved to the new 71 "FreeBSD-toolchain" package, which subsumes and obsoletes the 72 existing "FreeBSD-elftoolchain" package. If you use pkgbase and 73 need to compile software, you should install the new package and 74 ensure the old FreeBSD-elftoolchain* packages are completely removed. 75 7620250521: 77 Commit e64fe5ad3a23 removed in6_maxmtu and its setter in6_setmaxmtu(). 78 in6_maxmtu is used to store the max IPv6 MTU of all interfaces, 79 however it does not have any in-tree consumers since the introduction 80 from the KAME project. The removal should have little impact, and the 81 max IPv6 MTU can be easily retrieved by iterating over all the attached 82 interface if 3rd party modules need it. 83 8420250515: 85 Commit 772258c89f28 changed the internal API between the nfscommon 86 and nfscl modules. Both need to be built from updated sources. 87 8820250513: 89 The bridge(4) sysctl net.link.bridge.member_ifaddrs now defaults to 0, 90 meaning that interfaces added to a bridge may not have IP addresses 91 assigned. Refer to bridge(4) for more information. 92 9320250507: 94 UMASS quirks and auto-quirk probing has been overhauled. CAM now won't 95 send SYNCHRONIZE CACHE unless MODE PAGE 8 is present and valid. This 96 should allow more devices to work (since the auto quirk code was updated 97 in 14 and broke several e-readers and the like). Please send imp@freebsd.org 98 any regression reports. 99 10020250504: 101 Commit 9419e086e1a3 changed the internal API between the nfscommon 102 and nfscl modules. Both need to be built from updated sources. 103 10420250412: 105 LinuxKPI alloc routines were changed to return physically contiguous 106 memory where expected. These changes may require out-of-tree drivers 107 to be recompiled. 108 Bump __FreeBSD_version to 1500037 to be able to detect this change. 109 11020250409: 111 Intel iwlwifi firmware has been removed from the src repository. 112 Before updating their system, users of iwlwifi(4) or iwx(4) must 113 install the appropriate firmware for their chipset using fwget(8) or 114 building it from ports. 115 11620250314: 117 We now use LLVM's binary utilities (nm, objcopy, etc.) by default. 118 The WITHOUT_LLVM_BINUTILS src.conf(5) knob can be used to revert to 119 ELF Tool Chain tools if desired. 120 12120250303: 122 Commit 4a77657cbc01 changed the ABI between ipfw(8) and ipfw(4). 123 Please note that the old ipfw(8) binary will not work with the new 124 ipfw(4) module. Therefore, it is recommended to disable ipfw during 125 the upgrade, otherwise the host system may become inaccessible because 126 ipfw rules cannot be installed with the old binary. 127 12820250214: 129 Commit 4517fbfd4251 modified the internal API between the 130 nfscommon and nfscl modules. As such, both of these modules 131 need to be rebuilt from sources. 132 13320250201: 134 The NFS related daemons, that provide RPC services to the kernel: 135 gssd(8), rpcbind(8), rpc.tlsservd(8) and rpc.tlsclntd(8), now use a 136 different transport - netlink(4) socket instead of unix(4). Users of 137 NFS need to upgrade both kernel and world (binaries and libc) at once. 138 Also, any revision between 88cd1e17a7d8 and 99e5a70046da should be 139 avoided. 140 14120250129: 142 Defer the January 19, 2038 date limit in UFS1 filesystems to 143 February 7, 2106. This affects only UFS1 format filesystems. 144 See commit message 1111a44301da for details. 145 14620250127: 147 The Allwinner a10_timer driver has been renamed to aw_driver. If you 148 have a custom kernel configuration including the line 'device 149 a10_timer', it must be adjusted to 'device aw_timer'. The same applies 150 for device exclusions with 'nodevice'. 151 15220250106: 153 A new SOC_ROCKCHIP options appeared, so if you have a custom kernel configuration 154 targetting Rockchip SoC you need to add it so shared and mandatory drivers for 155 this SoC familly will be selected. 156 Also a new rk8xx device was added, this select the base driver for Rockchip PMIC. 157 15820241223: 159 The layout of NFS file handles for the tarfs, tmpfs, cd9660, and ext2fs 160 file systems has changed. An NFS server that exports any of these file 161 systems will need its clients to unmount and remount the exports. 162 16320241216: 164 The iwm(4) firmwares are no longer compiled as kernel modules but instead 165 shipped as raw files. For pkgbase users if you use iwm(4) you will need 166 to install the FreeBSD-firmware-iwm package. 167 16820241124: 169 The OpenBSD derived bc and dc implementations and the WITHOUT_GH_BC 170 option that allowed building them instead of the advanced version 171 imported more than 4 years ago have been removed. 172 17320241107: 174 The ng_ubt(4) driver now requires firmwares to be loaded on Realtek 175 adaptors with rtlbtfw(8) utility. It no longer attaches to devices 176 standing in bootloader mode. Firmware files are available in the 177 comms/rtlbt-firmware port. 178 17920241025: 180 The support for the rc_fast_and_loose variable has been removed from 181 rc.subr(8). Users setting rc_fast_and_loose on their systems are 182 advised to make sure their customizations to rc service scripts 183 do not depend on having a single shell environment shared across 184 all the rc service scripts during booting and shutdown. 185 18620241013: 187 The ciss driver was updated to cope better with hotplug events that 188 caused it to panic before, and to support more than 48 drives attached 189 to the card. These changes were made w/o benefit of hardware for testing 190 and ciss(4) users should be on the lookout for regressions. 191 19220240729: 193 The build now defaults to WITHOUT_CLEAN - i.e., no automatic clean 194 is performed at the beginning of buildworld or buildkernel. The 195 WITH_CLEAN src.conf(5) knob can be used to restore the previous 196 behaviour. 197 198 If you encounter incremental build issues, please report them to the 199 freebsd-current mailing list so that a special-case dependency can be 200 added, if necessary. 201 20220240715: 203 We now lean more heavily on ACPI enumeration for some traditional 204 devices. uart has moved from isa to acpi so the hints act as wiring 205 instead of device enumeration. Hints for parallel port, floppy, etc 206 have been removed. Before upgrading, grep your dmesg for lines like: 207 uart1: non-PNP ISA device will be removed from GENERIC in FreeBSD 15. 208 to see if you need to start including hints for the device on isa 209 in your loader.conf or device.hints file. APU1 (but not APU2) boards 210 are known to be affected, but there may be others. 211 21220240712: 213 Support for armv6 has been disconnected and is being removed. 214 21520240617: 216 ifconfig now treats IPv4 addresses without a width or mask as an error. 217 Specify the desired mask or width along with the IP address on the 218 ifconfig command line and in rc.conf. 219 22020240428: 221 OpenBSM auditing runtime (auditd, etc.) has been moved into the new 222 package FreeBSD-audit. If you use OpenBSM auditing and pkgbase, you 223 should install FreeBSD-audit. 224 22520240424: 226 cron, lpr, and ntpd have been moved from FreeBSD-utilities into their 227 own packages. If you use pkgbase, you should install the relevant 228 packages: FreeBSD-cron, FreeBSD-lp, or FreeBSD-ntp. 229 23020240406: 231 Clang, llvm, lld, lldb, compiler-rt, libc++, libunwind and openmp have 232 been upgraded to 18.1.6. It is important that you run `make delete-old` 233 as described in the COMMON ITEMS section, otherwise several libc++ 234 headers that are obsolete and need to be removed can cause compilation 235 errors in C++ programs. 236 23720240205: 238 For dynamically linked programs, system calls are now made from 239 libsys rather than libc. No change in linkage is required as 240 libsys is an auxiliary filter for libc. People building custom 241 images must ensure that libsys.so.7 is included. 242 24320240202: 244 Loader now also read configuration files listed in local_loader_conf_files. 245 Files listed here are the last ones read. And /boot/loader.conf.local was 246 moved from loader_conf_files to local_loader_conf_files leaving only 247 loader.conf and device.hints in loader_conf_files by default. 248 249 The following sequencing is applied: 250 251 1. Bootstrap: 252 /boot/defaults/loader.conf 253 254 2. Read loader_conf_files files: 255 /boot/device.hints 256 /boot/loader.conf 257 258 3. Read loader_conf_dirs files: 259 /boot/loader.conf.d/*.conf 260 261 4. And finally, rread local_loader_conf_files files: 262 /boot/loader.conf.local 263 26420240201: 265 sendmail 8.18.1 has been imported and merged. This version enforces 266 stricter RFC compliance by default, especially with respect to line 267 endings. This may cause issues with receiving messages from 268 non-compliant MTAs; please see the first 8.18.1 release note in 269 contrib/sendmail/RELEASE_NOTES for mitigations. 270 27120240111: 272 Commit cc760de2183f changed the internal interface between 273 the nfscommon and nfscl modules. As such, both need to be 274 rebuilt from sources. Therefore, __FreeBSD_version was 275 bumped to 1500010. 276 27720231120: 278 If you have an arm64 system that uses ACPI, you will need to update your 279 loader.efi in the ESP when you update past this point. Detection of ACPI 280 was moved earlier in the binary so the scripts could use it, but old 281 binaries don't have this, so we default to 'no ACPI' in this case. You can 282 undisable ACPI by doing 283 OK unset hint.acpi.0.disabled 284 This can also be used to recover any other system that was updated in the 285 small window where amd64 was also broken. 286 28720231113: 288 The WITHOUT_LLD_IS_LD option has been removed. When LLD is enabled 289 it is always installed as /usr/bin/ld. 290 29120231027: 292 Forward compatibility (running the new code on old kernels) for the 293 "ino64" project have been removed. The need for it has passed long ago. 294 29520231018: 296 Commit 57ce37f9dcd0 changed the internal KAPI between the 297 nfscommon and nfscl modules. Both must be rebuilt from sources. 298 29920231010: 300 dialog(1) has been replaced in base by bsddialog(1), while most of the 301 time replacing a dialog(1) call by a bsddialog(1) call works out of the 302 box, bsddialog(1) is not considered as a drop-in replacement for 303 dialog(1). 304 305 If you do depend on dialog(1) functionality, please install cdialog 306 from ports: 307 308 pkg install cdialog 309 31020230927: 311 The EARLY_AP_STARTUP kernel option is mandatory on x86. The option 312 has been added to DEFAULTS, so it should automatically be included in 313 custom kernel configurations without any additional change. 314 31520230922: 316 A new loader tunable net.pf.default_to_drop allows pf(4)’s default 317 behaviour to be changed from pass to drop. Previously this required 318 recompiling the kernel with the option PF_DEFAULT_TO_DROP. 319 32020230914: 321 Enable splitting out pkgbase manpages into separate packages by 322 default. To disable this, set WITHOUT_MANSPLITPKG=yes in src.conf. 323 32420230911: 325 Move standard include files to the clibs-dev package and move clang 326 internal libraries and headers to clang and clang-dev. Upgrading systems 327 installed using pkgbase past this change involves extra steps to allow 328 for these file moves: 329 330 pkg upgrade -y FreeBSD-utilities 331 pkg upgrade -y FreeBSD-utilities-dev 332 pkg upgrade -y 333 33420230909: 335 Enable vnet sysctl variables to be loader tunable. SYSCTLs which 336 belongs to VNETs can be initialized during early boot or module 337 loading if they are marked with CTLFLAG_TUN and there are 338 corresponding kernel environment variables. 339 34020230901: 341 The WITH_INIT_ALL_PATTERN and WITH_INIT_ALL_ZERO build options have 342 been replaced by INIT_ALL=pattern and INIT_ALL=zero respectively. 343 34420230824: 345 FreeBSD 15.0-CURRENT. 346 34720230817: 348 Serial communication (in boot loaders, kernel, and userland) has 349 been changed to default to 115200 bps, in line with common industry 350 practice and typcial firmware serial console redirection 351 configuration. 352 353 Note that the early x86 BIOS bootloader (i.e., boot0sio) does not 354 support rates above 9600 bps and is not changed. boot0sio users may 355 set BOOT_COMCONSOLE_SPEED=9600 to use 9600 for all of the boot 356 components, or use the standard boot0 and have the boot2 stage start 357 with the serial port at 115200. 358 35920230807: 360 Following the general removal of MIPS support, the ath(4) AHB bus- 361 frontend has been removed, too, and building of the PCI support is 362 integrated with the ath(4) main module again. As a result, there's 363 no longer a need for if_ath_pci_load="YES" in /boot/loader.conf or 364 "device ath_pci" in the kernel configuration. 365 36620230803: 367 MAXCPU has been increased to 1024 in the amd64 GENERIC kernel config. 368 Out-of-tree kernel modules will need to be rebuilt. 369 37020230724: 371 CAM has been mechanically updated s/u_int(64|32|16|8)_t/uint\1_t/g 372 to move to the standard uintXX_t types from the old, traditional 373 BSD u_intXX_t types. This should be a NOP, but may cause problems 374 for out of tree changes. The SIMs were not updated since most of 375 the old u_intXX_t uses weren't due to CAM interfaces. 376 37720230713: 378 stable/14 branch created. 379 38020230629: 381 The heuristic for detecting old chromebooks with an EC bug that requires 382 atkbdc driver workarounds has changed. There should be no functional 383 change, but if your old chromebook's keyboard stops working, please 384 file a PR and assign it to imp. 385 38620230623: 387 OpenSSL has been updated to version 3.0, including changes throughout 388 the base system. It is important to rebuild third-party software 389 after upgrading. 390 39120230619: 392 To enable pf rdr rules for connections initiated from the host, pf 393 filter rules can be optionally enabled for packets delivered 394 locally. This can change the behavior of rules which match packets 395 delivered to lo0. To enable this feature: 396 397 sysctl net.pf.filter_local=1 398 service pf restart 399 400 When enabled, its best to ensure that packets delivered locally are not 401 filtered, e.g. by adding a 'skip on lo' rule. 402 40320230613: 404 Improvements to libtacplus(8) mean that tacplus.conf(5) now 405 follows POSIX shell syntax rules. This may cause TACACS+ 406 authentication to fail if the shared secret contains a single 407 quote, double quote, or backslash character which isn't 408 already properly quoted or escaped. 409 41020230612: 411 Belatedly switch the default nvme block device on x86 from nvd to nda. 412 nda created nvd compatibility links by default, so this should be a 413 nop. If this causes problems for your application, set hw.nvme.use_nvd=1 414 in your loader.conf or add `options NVME_USE_NVD=1` to your kernel 415 config. To disable the nvd compatibility aliases, add 416 kern.cam.nda.nvd_compat=0 to loader.conf. The default has been nda on 417 all non-x86 platforms for some time now. If you need to fall back, 418 please email imp@freebsd.org about why. 419 420 Encrypted swap partitions need to be changed from nvd to nda if you 421 migrate, or you need to use the above to switch back to nvd. 422 42320230422: 424 Remove portsnap(8). Users are encouraged to obtain the ports tree 425 using git instead. 426 42720230420: 428 Add jobs.mk to save typing. Enables -j${JOB_MAX} and logging 429 eg. 430 make buildworld-jobs 431 runs 432 make -j${JOB_MAX} buildworld > ../buildworld.log 2>&1 433 434 where JOB_MAX is derrived from ncpus in local.sys.mk if not set in env. 435 43620230316: 437 Video related devices for some arm devices have been renamed. 438 If you have a custom kernel config and want to use hdmi output on 439 IMX6 board you need to add "device dwc_hdmi" "device imx6_hdmi" and 440 "device imx6_ipu" to it. 441 If you have a custom kernel config and want to use hdmi output on 442 TI AM335X board you need to add "device tda19988" to it. 443 If you add "device hdmi" in it you need to remove it as it doesn't 444 exist anymore. 445 44620230221: 447 Introduce new kernel options KBD_DELAY1 and KBD_DELAY2. See atkbdc(4) 448 for details. 449 45020230206: 451 sshd now defaults to having X11Forwarding disabled, following upstream. 452 Administrators who wish to enable X11Forwarding should add 453 `X11Forwarding yes` to /etc/ssh/sshd_config. 454 45520230204: 456 Since commit 75d41cb6967 Huawei 3G/4G LTE Mobile Devices do not default 457 to ECM, but NCM mode and need u3g and ucom modules loaded. See cdce(4). 458 45920230130: 460 As of commit 7c40e2d5f685, the dependency on netlink(4) has been added 461 to the linux_common(4) module. Users relying on linux_common may need 462 to complile netlink(4) module if it is not present in their kernel. 463 46420230126: 465 The WITHOUT_CXX option has been removed. C++ components in the base 466 system are now built unconditionally. 467 46820230113: 469 LinuxKPI pci.h changes may require out-of-tree drivers to be recompiled. 470 Bump _FreeBSD_version to 1400078 to be able to detect this change. 471 47220221212: 473 llvm-objump is now always installed as objdump. Previously there was 474 no /usr/bin/objdump unless the WITH_LLVM_BINUTILS knob was used. 475 476 Some LLVM objdump options have a different output format compared to 477 GNU objdump; readelf is available for inspecting ELF files, and GNU 478 objdump is available from the devel/binutils port or package. 479 48020221205: 481 dma(8) has replaced sendmail(8) as the default mta. For people willing 482 to reenable sendmail(8): 483 484 $ cp /usr/share/examples/sendmail/mailer.conf /etc/mail/mailer.conf 485 486 and add sendmail_enable="YES" to rc.conf. 487 48820221204: 489 hw.bus.disable_failed_devices has changed from 'false' to 'true' by 490 default. Now if newbus succeeds in probing a device, but fails to attach 491 the device, we'll disable the device. In the past, we'd keep retrying 492 the device on each new driver loaded. To get that behavior now, one 493 needs to use devctl to re-enable the device, and reprobe it (or set 494 the sysctl/tunable hw.bus.disable_failed_devices=false). 495 496 NOTE: This was reverted 20221205 due to unexpected compatibility issues 497 49820221122: 499 pf no longer accepts 'scrub fragment crop' or 'scrub fragment drop-ovl'. 500 These configurations are no longer automatically reinterpreted as 501 'scrub fragment reassemble'. 502 50320221121: 504 The WITHOUT_CLANG_IS_CC option has been removed. When Clang is enabled 505 it is always installed as /usr/bin/cc (and c++, cpp). 506 50720221026: 508 Some programs have been moved into separate packages. It is recommended 509 for pkgbase users to do: 510 511 pkg install FreeBSD-dhclient FreeBSD-geom FreeBSD-resolvconf \ 512 FreeBSD-devd FreeBSD-devmatch 513 514 after upgrading to restore all the component that were previously 515 installed. 516 51720221002: 518 OPIE has been removed from the base system. If needed, it can 519 be installed from ports (security/opie) or packages (opie). 520 Otherwise, make sure that your PAM policies do not reference 521 pam_opie or pam_opieaccess. 522 52320220610: 524 LinuxKPI pm.h changes require an update to the latest drm-kmod version 525 before re-compiling to avoid errors. 526 52720211230: 528 The macros provided for the manipulation of CPU sets (e.g. CPU_AND) 529 have been modified to take 2 source arguments instead of only 1. 530 Externally maintained sources that use these macros will have to 531 be adapted. The FreeBSD version has been bumped to 1400046 to 532 reflect this change. 533 53420211214: 535 A number of the kernel include files are able to be included by 536 themselves. A test has been added to buildworld to enforce this. 537 53820211209: 539 Remove mips as a recognized target. This starts the decommissioning of 540 mips support in FreeBSD. mips related items will be removed wholesale in 541 the coming days and weeks. 542 543 This broke the NO_CLEAN build for some people. Either do a clean build 544 or touch 545 lib/clang/include/llvm/Config/Targets.def 546 lib/clang/include/llvm/Config/AsmParsers.def 547 lib/clang/include/llvm/Config/Disassemblers.def 548 lib/clang/include/llvm/Config/AsmPrinters.def 549 before the build to force everything to rebuild that needs to. 550 55120211202: 552 Unbound support for RFC8375: The special-use domain 'home.arpa' is 553 by default blocked. To unblock it use a local-zone nodefault 554 statement in unbound.conf: 555 local-zone: "home.arpa." nodefault 556 557 Or use another type of local-zone to override with your choice. 558 559 The reason for this is discussed in Section 6.1 of RFC8375: 560 Because 'home.arpa.' is not globally scoped and cannot be secured 561 using DNSSEC based on the root domain's trust anchor, there is no way 562 to tell, using a standard DNS query, in which homenet scope an answer 563 belongs. Consequently, users may experience surprising results with 564 such names when roaming to different homenets. 565 56620211110: 567 Commit b8d60729deef changed the TCP congestion control framework so 568 that any of the included congestion control modules could be 569 the single module built into the kernel. Previously newreno 570 was automatically built in through direct reference. As of 571 this commit you are required to declare at least one congestion 572 control module (e.g. 'options CC_NEWRENO') and to also declare a 573 default using the CC_DEFAULT option (e.g. options CC_DEFAULT="newreno\"). 574 The GENERIC configuration includes CC_NEWRENO and defines newreno 575 as the default. If no congestion control option is built into the 576 kernel and you are including networking, the kernel compile will 577 fail. Also if no default is declared the kernel compile will fail. 578 57920211118: 580 Mips has been removed from universe builds. It will be removed from the 581 tree shortly. 582 58320211106: 584 Commit f0c9847a6c47 changed the arguments for VOP_ALLOCATE. 585 The NFS modules must be rebuilt from sources and any out 586 of tree file systems that implement their own VOP_ALLOCATE 587 may need to be modified. 588 58920211022: 590 The synchronous PPP kernel driver sppp(4) has been removed. 591 The cp(4) and ce(4) drivers are now always compiled with netgraph(4) 592 support, formerly enabled by NETGRAPH_CRONYX option. 593 59420211020: 595 sh(1) is now the default shell for the root user. To force root to use 596 the csh shell, please run the following command as root: 597 598 # chsh -s csh 599 60020211004: 601 Ncurses distribution has been split between libtinfow and libncurses 602 with libncurses.so becoming a linker (ld) script to seamlessly link 603 to libtinfow as needed. Bump _FreeBSD_version to 1400035 to reflect 604 this change. 605 60620210923: 607 As of commit 8160a0f62be6, the dummynet module no longer depends on the 608 ipfw module. Dummynet can now be used by pf as well as ipfw. As such 609 users who relied on this dependency may need to include ipfw in the 610 list of modules to load on their systems. 611 61220210922: 613 As of commit 903873ce1560, the mixer(8) utility has got a slightly 614 new syntax. Please refer to the mixer(8) manual page for more 615 information. The old mixer utility can be installed from ports: 616 audio/freebsd-13-mixer 617 61820210911: 619 As of commit 55089ef4f8bb, the global variable nfs_maxcopyrange has 620 been deleted from the nfscommon.ko. As such, nfsd.ko must be built 621 from up to date sources to avoid an undefined reference when 622 being loaded. 623 62420210817: 625 As of commit 62ca9fc1ad56 OpenSSL no longer enables kernel TLS 626 by default. Users can enable kernel TLS via the "KTLS" SSL 627 option. This can be enabled globally by using a custom 628 OpenSSL config file via OPENSSL_CONF or via an 629 application-specific configuration option for applications 630 which permit setting SSL options via SSL_CONF_cmd(3). 631 63220210811: 633 Commit 3ad1e1c1ce20 changed the internal KAPI between the NFS 634 modules. Therefore, all need to be rebuilt from sources. 635 63620210730: 637 Commit b69019c14cd8 removes pf's DIOCGETSTATESNV ioctl. 638 As of be70c7a50d32 it is no longer used by userspace, but it does mean 639 users may not be able to enumerate pf states if they update the kernel 640 past b69019c14cd8 without first updating userspace past be70c7a50d32. 641 64220210729: 643 As of commit 01ad0c007964 if_bridge member interfaces can no longer 644 change their MTU. Changing the MTU of the bridge itself will change the 645 MTU on all member interfaces instead. 646 64720210716: 648 Commit ee29e6f31111 changed the internal KAPI between the nfscommon 649 and nfsd modules. Therefore, both need to be rebuilt from sources. 650 Bump __FreeBSD_version to 1400026 for this KAPI change. 651 65220210715: 653 The 20210707 awk update brought in a change in behavior. This has 654 been corrected as of d4d252c49976. Between these dates, if you 655 installed a new awk binary, you may not be able to build a new 656 kernel because the change in behavior affected the genoffset 657 script used to build the kernel. If you did update, the fix is 658 to update your sources past the above hash and do 659 % cd usr.bin/awk 660 % make clean all 661 % sudo -E make install 662 to enable building kernels again. 663 66420210708: 665 Commit 1e0a518d6548 changed the internal KAPI between the NFS 666 modules. They all need to be rebuilt from sources. I did not 667 bump __FreeBSD_version, since it was bumped recently. 668 66920210707: 670 awk has been updated to the latest one-true-awk version 20210215. 671 This contains a number of minor bug fixes. 672 67320210624: 674 The NFSv4 client now uses the highest minor version of NFSv4 675 supported by the NFSv4 server by default instead of minor version 0, 676 for NFSv4 mounts. 677 The "minorversion" mount option may be used to override this default. 678 67920210618: 680 Bump __FreeBSD_version to 1400024 for LinuxKPI changes. 681 Most notably netdev.h can change now as the (last) dependencies 682 (mlx4/ofed) are now using struct ifnet directly, but also for PCI 683 additions and others. 684 68520210618: 686 The directory "blacklisted" under /usr/share/certs/ has been 687 renamed to "untrusted". 688 68920210611: 690 svnlite has been removed from base. Should you need svn for any reason 691 please install the svn package or port. 692 69320210611: 694 Commit e1a907a25cfa changed the internal KAPI between the krpc 695 and nfsserver. As such, both modules must be rebuilt from 696 sources. Bump __FreeBSD_version to 1400022. 697 69820210610: 699 The an(4) driver has been removed from FreeBSD. 700 70120210608: 702 The vendor/openzfs branch was renamed to vendor/openzfs/legacy to 703 start tracking OpenZFS upstream more closely. Please see 704https://lists.freebsd.org/archives/freebsd-current/2021-June/000153.html 705 for details on how to correct any errors that might result. The 706 short version is that you need to remove the old branch locally: 707 git update-ref -d refs/remotes/freebsd/vendor/openzfs 708 (assuming your upstream origin is named 'freebsd'). 709 71020210525: 711 Commits 17accc08ae15 and de102f870501 add new files to LinuxKPI 712 which break drm-kmod. In addition various other additions where 713 committed. Bump __FreeBSD_version to 1400015 to be able to 714 detect this. 715 71620210513: 717 Commit ca179c4d74f2 changed the package in which the OpenSSL 718 libraries and utilities are packaged. 719 It is recommended for pkgbase user to do: 720 pkg install -f FreeBSD-openssl 721 before pkg upgrade otherwise some dependencies might not be met 722 and pkg will stop working as libssl will not be present anymore 723 on the system. 724 72520210426: 726 Commit 875977314881 changed the internal KAPI between 727 the nfsd and nfscommon modules. As such these modules 728 need to be rebuilt from sources. 729 Without this patch in your NFSv4.1/4.2 server, enabling 730 delegations by setting vfs.nfsd.issue_delegations non-zero 731 is not recommended. 732 73320210411: 734 Commit 7763814fc9c2 changed the internal KAPI between 735 the krpc and NFS. As such, the krpc, nfscommon and 736 nfscl modules must all be rebuilt from sources. 737 Without this patch, NFSv4.1/4.2 mounts should not 738 be done with the nfscbd(8) daemon running, to avoid 739 needing a working back channel for server->client RPCs. 740 74120210330: 742 Commit 01ae8969a9ee fixed the NFSv4.1/4.2 server so that it 743 handles binding of the back channel as required by RFC5661. 744 Until this patch is in your server, avoid use of the "nconnects" 745 mount option for Linux NFSv4.1/4.2 mounts. 746 74720210225: 748 For 64-bit architectures the base system is now built with Position 749 Independent Executable (PIE) support enabled by default. It may be 750 disabled using the WITHOUT_PIE knob. A clean build is required. 751 75220210128: 753 Various LinuxKPI functionality was added which conflicts with DRM. 754 Please update your drm-kmod port to after the __FreeBSD_version 1400003 755 update. 756 75720210121: 758 stable/13 branch created. 759 76020210108: 761 PC Card attachments for all devices have been removed. In the case of 762 wi and cmx, the entire drivers were removed because they were only 763 PC Card devices. FreeBSD_version 1300134 should be used for this 764 since it was bumped so recently. 765 76620210107: 767 Transport-independent parts of HID support have been split off the USB 768 code in to separate subsystem. Kernel configs which include one of 769 ums, ukbd, uhid, atp, wsp, wmt, uaudio, ugold or ucycom drivers should 770 be updated with adding of "device hid" line. 771 77220210105: 773 ncurses installation has been modified to only keep the widechar 774 enabled version. Incremental build is broken for that change, so it 775 requires a clean build. 776 77720201223: 778 The FreeBSD project has migrated from Subversion to Git. Temporary 779 instructions can be found at 780 https://github.com/bsdimp/freebsd-git-docs/blob/main/src-cvt.md 781 and other documents in that repo. 782 78320201216: 784 The services database has been updated to cover more of the basic 785 services expected in a modern system. The database is big enough 786 that it will cause issues in mergemaster in Releases previous to 787 12.2 and 11.3, or in very old current systems from before r358154. 788 78920201215: 790 Obsolete in-tree GDB 6.1.1 has been removed. GDB (including kgdb) 791 may be installed from ports or packages. 792 79320201124: 794 ping6 has been merged into ping. It can now be called as "ping -6". 795 See ping(8) for details. 796 79720201108: 798 Default value of net.add_addr_allfibs has been changed to 0. 799 If you have multi-fib configuration and rely on existence of all 800 interface routes in every fib, you need to set the above sysctl to 1. 801 80220201030: 803 The internal pre-processor in the calendar(1) program has been 804 extended to support more C pre-processor commands (e.g. #ifdef, #else, 805 and #undef) and to detect unbalanced conditional statements. 806 Error messages have been extended to include the filename and line 807 number if processing stops to help fixing malformed data files. 808 80920201026: 810 All the data files for the calendar(1) program, except calendar.freebsd, 811 have been moved to the deskutils/calendar-data port, much like the 812 jewish calendar entries were moved to deskutils/hebcal years ago. After 813 make delete-old-files, you need to install it to retain full 814 functionality. calendar(1) will issue a reminder for files it can't 815 find. 816 81720200923: 818 LINT files are no longer generated. We now include the relevant NOTES 819 files. Note: This may cause conflicts with updating in some cases. 820 find sys -name LINT\* -delete 821 is suggested across this commit to remove the generated LINT files. 822 823 If you have tried to update with generated files there, the svn 824 command you want to un-auger the tree is 825 cd sys/amd64/conf 826 svn revert -R . 827 and then do the above find from the top level. Substitute 'amd64' 828 above with where the error message indicates a conflict. 829 83020200824: 831 OpenZFS support has been integrated. Do not upgrade root pools until 832 the loader is updated to support zstd. Furthermore, we caution against 833 'zpool upgrade' for the next few weeks. The change should be transparent 834 unless you want to use new features. 835 836 Not all "NO_CLEAN" build scenarios work across these changes. Many 837 scenarios have been tested and fixed, but rebuilding kernels without 838 rebuilding world may fail. 839 840 The ZFS cache file has moved from /boot to /etc to match the OpenZFS 841 upstream default. A fallback to /boot has been added for mountroot. 842 843 Pool auto import behavior at boot has been moved from the kernel module 844 to an explicit "zpool import -a" in one of the rc scripts enabled by 845 zfs_enable=YES. This means your non-root zpools won't auto import until 846 you upgrade your /etc/rc.d files. 847 84820200824: 849 The resume code now notifies devd with the 'kernel' system 850 rather than the old 'kern' subsystem to be consistent with 851 other use. The old notification will be created as well, but 852 will be removed prior to FreeBSD 14.0. 853 85420200821: 855 r362275 changed the internal API between the kernel RPC and the 856 NFS modules. As such, all the modules must be recompiled from 857 sources. 858 85920200817: 860 r364330 modified the internal API used between the NFS modules. 861 As such, all the NFS modules must be re-compiled from sources. 862 86320200816: 864 Clang, llvm, lld, lldb, compiler-rt, libc++, libunwind and openmp have 865 been upgraded to 11.0.0. Please see the 20141231 entry below for 866 information about prerequisites and upgrading, if you are not already 867 using clang 3.5.0 or higher. 868 86920200810: 870 r364092 modified the internal ABI used between the kernel NFS 871 modules. As such, all of these modules need to be rebuilt 872 from sources, so a version bump was done. 873 87420200807: 875 Makefile.inc has been updated to work around the issue documented in 876 20200729. It was a case where the optimization of using symbolic links 877 to point to binaries created a situation where we'd run new binaries 878 with old libraries starting midway through the installworld process. 879 88020200729: 881 r363679 has redefined some undefined behavior in regcomp(3); notably, 882 extraneous escapes of most ordinary characters will no longer be 883 accepted. An exp-run has identified all of the problems with this in 884 ports, but other non-ports software may need extra escapes removed to 885 continue to function. 886 887 Because of this change, installworld may encounter the following error 888 from rtld: Undefined symbol "regcomp@FBSD_1.6" -- It is imperative that 889 you do not halt installworld. Instead, let it run to completion (whether 890 successful or not) and run installworld once more. 891 89220200627: 893 A new implementation of bc and dc has been imported in r362681. This 894 implementation corrects non-conformant behavior of the previous bc 895 and adds GNU bc compatible options. It offers a number of extensions, 896 is much faster on large values, and has support for message catalogs 897 (a number of languages are already supported, contributions of further 898 languages welcome). The option WITHOUT_GH_BC can be used to build the 899 world with the previous versions of bc and dc. 900 90120200625: 902 r362639 changed the internal API used between the NFS kernel modules. 903 As such, they all need to be rebuilt from sources. 904 90520200613: 906 r362158 changed the arguments for VFS_CHECKEXP(). As such, any 907 out of tree file systems need to be modified and rebuilt. 908 Also, any file systems that are modules must be rebuilt. 909 91020200604: 911 read(2) of a directory fd is now rejected by default. root may 912 re-enable it for system root only on non-ZFS filesystems with the 913 security.bsd.allow_read_dir sysctl(8) MIB if 914 security.bsd.suser_enabled=1. 915 916 It may be advised to setup aliases for grep to default to `-d skip` if 917 commonly non-recursively grepping a list that includes directories and 918 the potential for the resulting stderr output is not tolerable. Example 919 aliases are now installed, commented out, in /root/.cshrc and 920 /root/.shrc. 921 92220200523: 923 Clang, llvm, lld, lldb, compiler-rt, libc++, libunwind and openmp have 924 been upgraded to 10.0.1. Please see the 20141231 entry below for 925 information about prerequisites and upgrading, if you are not already 926 using clang 3.5.0 or higher. 927 92820200512: 929 Support for obsolete compilers has been removed from the build system. 930 Clang 6 and GCC 6.4 are the minimum supported versions. 931 93220200424: 933 closefrom(2) has been moved under COMPAT12, and replaced in libc with a 934 stub that calls close_range(2). If using a custom kernel configuration, 935 you may want to ensure that the COMPAT_FREEBSD12 option is included, as 936 a slightly older -CURRENT userland and older FreeBSD userlands may not 937 be functional without closefrom(2). 938 93920200414: 940 Upstream DTS from Linux 5.6 was merged and they now have the SID 941 and THS (Secure ID controller and THermal Sensor) node present. 942 The DTB overlays have now been removed from the tree for the H3/H5 and 943 A64 SoCs and the aw_sid and aw_thermal driver have been updated to 944 deal with upstream DTS. If you are using those overlays you need to 945 remove them from loader.conf and update the DTBs on the FAT partition. 946 94720200310: 948 Clang, llvm, lld, lldb, compiler-rt, libc++, libunwind and openmp have 949 been upgraded to 10.0.0. Please see the 20141231 entry below for 950 information about prerequisites and upgrading, if you are not already 951 using clang 3.5.0 or higher. 952 95320200309: 954 The amd(8) automount daemon has been removed from the source tree. 955 As of FreeBSD 10.1 autofs(5) is the preferred tool for automounting. 956 amd is still available in the sysutils/am-utils port. 957 95820200301: 959 Removed brooktree driver (bktr.4) from the tree. 960 96120200229: 962 The WITH_GPL_DTC option has been removed. The BSD-licenced device tree 963 compiler in usr.bin/dtc is used on all architectures which use dtc, and 964 the GPL dtc is available (if needed) from the sysutils/dtc port. 965 96620200229: 967 The WITHOUT_LLVM_LIBUNWIND option has been removed. LLVM's libunwind 968 is used by all supported CPU architectures. 969 97020200229: 971 GCC 4.2.1 has been removed from the tree. The WITH_GCC, 972 WITH_GCC_BOOTSTRAP, and WITH_GNUCXX options are no longer available. 973 Users who wish to build FreeBSD with GCC must use the external toolchain 974 ports or packages. 975 97620200220: 977 ncurses has been updated to a newer version (6.2-20200215). Given the ABI 978 has changed, users will have to rebuild all the ports that are linked to 979 ncurses. 980 98120200217: 982 The size of struct vnet and the magic cookie have changed. 983 Users need to recompile libkvm and all modules using VIMAGE 984 together with their new kernel. 985 98620200212: 987 Defining the long deprecated NO_CTF, NO_DEBUG_FILES, NO_INSTALLLIB, 988 NO_MAN, NO_PROFILE, and NO_WARNS variables is now an error. Update 989 your Makefiles and scripts to define MK_<var>=no instead as required. 990 991 One exception to this is that program or library Makefiles should 992 define MAN to empty rather than setting MK_MAN=no. 993 99420200108: 995 Clang/LLVM is now the default compiler and LLD the default 996 linker for riscv64. 997 99820200107: 999 make universe no longer uses GCC 4.2.1 on any architectures. 1000 Architectures not supported by in-tree Clang/LLVM require an 1001 external toolchain package. 1002 100320200104: 1004 GCC 4.2.1 is now not built by default, as part of the GCC 4.2.1 1005 retirement plan. Specifically, the GCC, GCC_BOOTSTRAP, and GNUCXX 1006 options default to off for all supported CPU architectures. As a 1007 short-term transition aid they may be enabled via WITH_* options. 1008 GCC 4.2.1 is expected to be removed from the tree on 2020-03-31. 1009 101020200102: 1011 Support for armv5 has been disconnected and is being removed. The 1012 machine combination MACHINE=arm MACHINE_ARCH=arm is no longer valid. 1013 You must now use a MACHINE_ARCH of armv6 or armv7. The default 1014 MACHINE_ARCH for MACHINE=arm is now armv7. 1015 101620191226: 1017 Clang/LLVM is now the default compiler for all powerpc architectures. 1018 LLD is now the default linker for powerpc64. The change for powerpc64 1019 also includes a change to the ELFv2 ABI, incompatible with the existing 1020 ABI. 1021 102220191226: 1023 Kernel-loadable random(4) modules are no longer unloadable. 1024 102520191222: 1026 Clang, llvm, lld, lldb, compiler-rt, libc++, libunwind and openmp have 1027 been upgraded to 9.0.1. Please see the 20141231 entry below for 1028 information about prerequisites and upgrading, if you are not already 1029 using clang 3.5.0 or higher. 1030 103120191212: 1032 r355677 has modified the internal interface used between the 1033 NFS modules in the kernel. As such, they must all be upgraded 1034 simultaneously. I will do a version bump for this. 1035 103620191205: 1037 The root certificates of the Mozilla CA Certificate Store have been 1038 imported into the base system and can be managed with the certctl(8) 1039 utility. If you have installed the security/ca_root_nss port or package 1040 with the ETCSYMLINK option (the default), be advised that there may be 1041 differences between those included in the port and those included in 1042 base due to differences in nss branch used as well as general update 1043 frequency. Note also that certctl(8) cannot manage certs in the 1044 format used by the security/ca_root_nss port. 1045 104620191120: 1047 The amd(8) automount daemon has been disabled by default, and will be 1048 removed in the future. As of FreeBSD 10.1 the autofs(5) is available 1049 for automounting. 1050 105120191107: 1052 The nctgpio and wbwd drivers have been moved to the superio bus. 1053 If you have one of these drivers in a kernel configuration, then 1054 you should add device superio to it. If you use one of these drivers 1055 as a module and you compile a custom set of modules, then you should 1056 add superio to the set. 1057 105820191021: 1059 KPIs for network drivers to access interface addresses have changed. 1060 Users need to recompile NIC driver modules together with kernel. 1061 106220191021: 1063 The net.link.tap.user_open sysctl no longer prevents user opening of 1064 already created /dev/tapNN devices. Access is still controlled by 1065 node permissions, just like tun devices. The net.link.tap.user_open 1066 sysctl is now used only to allow users to perform devfs cloning of 1067 tap devices, and the subsequent open may not succeed if the user is not 1068 in the appropriate group. This sysctl may be deprecated/removed 1069 completely in the future. 1070 107120191009: 1072 mips, powerpc, and sparc64 are no longer built as part of 1073 universe / tinderbox unless MAKE_OBSOLETE_GCC is defined. If 1074 not defined, mips, powerpc, and sparc64 builds will look for 1075 the xtoolchain binaries and if installed use them for universe 1076 builds. As llvm 9.0 becomes vetted for these architectures, they 1077 will be removed from the list. 1078 107920191009: 1080 Clang, llvm, lld, lldb, compiler-rt, libc++, libunwind and openmp have 1081 been upgraded to 9.0.0. Please see the 20141231 entry below for 1082 information about prerequisites and upgrading, if you are not already 1083 using clang 3.5.0 or higher. 1084 108520191003: 1086 The hpt27xx, hptmv, hptnr, and hptrr drivers have been removed from 1087 GENERIC. They are available as modules and can be loaded by adding 1088 to /boot/loader.conf hpt27xx_load="YES", hptmv_load="YES", 1089 hptnr_load="YES", or hptrr_load="YES", respectively. 1090 109120190913: 1092 ntpd no longer by default locks its pages in memory, allowing them 1093 to be paged out by the kernel. Use rlimit memlock to restore 1094 historic BSD behaviour. For example, add "rlimit memlock 32" 1095 to ntp.conf to lock up to 32 MB of ntpd address space in memory. 1096 109720190823: 1098 Several of ping6's options have been renamed for better consistency 1099 with ping. If you use any of -ARWXaghmrtwx, you must update your 1100 scripts. See ping6(8) for details. 1101 110220190727: 1103 The vfs.fusefs.sync_unmount and vfs.fusefs.init_backgrounded sysctls 1104 and the "-o sync_unmount" and "-o init_backgrounded" mount options have 1105 been removed from mount_fusefs(8). You can safely remove them from 1106 your scripts, because they had no effect. 1107 1108 The vfs.fusefs.fix_broken_io, vfs.fusefs.sync_resize, 1109 vfs.fusefs.refresh_size, vfs.fusefs.mmap_enable, 1110 vfs.fusefs.reclaim_revoked, and vfs.fusefs.data_cache_invalidate 1111 sysctls have been removed. If you felt the need to set any of them to 1112 a non-default value, please tell asomers@FreeBSD.org why. 1113 111420190713: 1115 Default permissions on the /var/account/acct file (and copies of it 1116 rotated by periodic daily scripts) are changed from 0644 to 0640 1117 because the file contains sensitive information that should not be 1118 world-readable. If the /var/account directory must be created by 1119 rc.d/accounting, the mode used is now 0750. Admins who use the 1120 accounting feature are encouraged to change the mode of an existing 1121 /var/account directory to 0750 or 0700. 1122 112320190620: 1124 Entropy collection and the /dev/random device are no longer optional 1125 components. The "device random" option has been removed. 1126 Implementations of distilling algorithms can still be made loadable 1127 with "options RANDOM_LOADABLE" (e.g., random_fortuna.ko). 1128 112920190612: 1130 Clang, llvm, lld, lldb, compiler-rt, libc++, libunwind and openmp have 1131 been upgraded to 8.0.1. Please see the 20141231 entry below for 1132 information about prerequisites and upgrading, if you are not already 1133 using clang 3.5.0 or higher. 1134 113520190608: 1136 A fix was applied to i386 kernel modules to avoid panics with 1137 dpcpu or vnet. Users need to recompile i386 kernel modules 1138 having pcpu or vnet sections or they will refuse to load. 1139 114020190513: 1141 User-wired pages now have their own counter, 1142 vm.stats.vm.v_user_wire_count. The vm.max_wired sysctl was renamed 1143 to vm.max_user_wired and changed from an unsigned int to an unsigned 1144 long. bhyve VMs wired with the -S are now subject to the user 1145 wiring limit; the vm.max_user_wired sysctl may need to be tuned to 1146 avoid running into the limit. 1147 114820190507: 1149 The IPSEC option has been removed from GENERIC. Users requiring 1150 ipsec(4) must now load the ipsec(4) kernel module. 1151 115220190507: 1153 The tap(4) driver has been folded into tun(4), and the module has been 1154 renamed to tuntap. You should update any kld_list="if_tap" or 1155 kld_list="if_tun" entries in /etc/rc.conf, if_tap_load="YES" or 1156 if_tun_load="YES" entries in /boot/loader.conf to load the if_tuntap 1157 module instead, and "device tap" or "device tun" entries in kernel 1158 config files to select the tuntap device instead. 1159 116020190418: 1161 The following knobs have been added related to tradeoffs between 1162 safe use of the random device and availability in the absence of 1163 entropy: 1164 1165 kern.random.initial_seeding.bypass_before_seeding: tunable; set 1166 non-zero to bypass the random device prior to seeding, or zero to 1167 block random requests until the random device is initially seeded. 1168 For now, set to 1 (unsafe) by default to restore pre-r346250 boot 1169 availability properties. 1170 1171 kern.random.initial_seeding.read_random_bypassed_before_seeding: 1172 read-only diagnostic sysctl that is set when bypass is enabled and 1173 read_random(9) is bypassed, to enable programmatic handling of this 1174 initial condition, if desired. 1175 1176 kern.random.initial_seeding.arc4random_bypassed_before_seeding: 1177 Similar to the above, but for arc4random(9) initial seeding. 1178 1179 kern.random.initial_seeding.disable_bypass_warnings: tunable; set 1180 non-zero to disable warnings in dmesg when the same conditions are 1181 met as for the diagnostic sysctls above. Defaults to zero, i.e., 1182 produce warnings in dmesg when the conditions are met. 1183 118420190416: 1185 The loadable random module KPI has changed; the random_infra_init() 1186 routine now requires a 3rd function pointer for a bool (*)(void) 1187 method that returns true if the random device is seeded (and 1188 therefore unblocked). 1189 119020190404: 1191 r345895 reverts r320698. This implies that an nfsuserd(8) daemon 1192 built from head sources between r320757 (July 6, 2017) and 1193 r338192 (Aug. 22, 2018) will not work unless the "-use-udpsock" 1194 is added to the command line. 1195 nfsuserd daemons built from head sources that are post-r338192 are 1196 not affected and should continue to work. 1197 119820190320: 1199 The fuse(4) module has been renamed to fusefs(4) for consistency with 1200 other filesystems. You should update any kld_load="fuse" entries in 1201 /etc/rc.conf, fuse_load="YES" entries in /boot/loader.conf, and 1202 "options FUSE" entries in kernel config files. 1203 120420190304: 1205 Clang, llvm, lld, lldb, compiler-rt and libc++ have been upgraded to 1206 8.0.0. Please see the 20141231 entry below for information about 1207 prerequisites and upgrading, if you are not already using clang 3.5.0 1208 or higher. 1209 121020190226: 1211 geom_uzip(4) depends on the new module xz. If geom_uzip is statically 1212 compiled into your custom kernel, add 'device xz' statement to the 1213 kernel config. 1214 121520190219: 1216 drm and drm2 have been removed from the tree. Please see 1217 https://wiki.freebsd.org/Graphics for the latest information on 1218 migrating to the drm ports. 1219 122020190131: 1221 Iflib is no longer unconditionally compiled into the kernel. Drivers 1222 using iflib and statically compiled into the kernel, now require 1223 the 'device iflib' config option. For the same drivers loaded as 1224 modules on kernels not having 'device iflib', the iflib.ko module 1225 is loaded automatically. 1226 122720190125: 1228 The IEEE80211_AMPDU_AGE and AH_SUPPORT_AR5416 kernel configuration 1229 options no longer exist since r343219 and r343427 respectively; 1230 nothing uses them, so they should be just removed from custom 1231 kernel config files. 1232 123320181230: 1234 r342635 changes the way efibootmgr(8) works by requiring users to add 1235 the -b (bootnum) parameter for commands where the bootnum was previously 1236 specified with each option. For example 'efibootmgr -B 0001' is now 1237 'efibootmgr -B -b 0001'. 1238 123920181220: 1240 r342286 modifies the NFSv4 server so that it obeys vfs.nfsd.nfs_privport 1241 in the same as it is applied to NFSv2 and 3. This implies that NFSv4 1242 servers that have vfs.nfsd.nfs_privport set will only allow mounts 1243 from clients using a reserved port. Since both the FreeBSD and Linux 1244 NFSv4 clients use reserved ports by default, this should not affect 1245 most NFSv4 mounts. 1246 124720181219: 1248 The XLP config has been removed. We can't support 64-bit atomics in this 1249 kernel because it is running in 32-bit mode. XLP users must transition 1250 to running a 64-bit kernel (XLP64 or XLPN32). 1251 1252 The mips GXEMUL support has been removed from FreeBSD. MALTA* + qemu is 1253 the preferred emulator today and we don't need two different ones. 1254 1255 The old sibyte / swarm / Broadcom BCM1250 support has been 1256 removed from the mips port. 1257 125820181211: 1259 Clang, llvm, lld, lldb, compiler-rt and libc++ have been upgraded to 1260 7.0.1. Please see the 20141231 entry below for information about 1261 prerequisites and upgrading, if you are not already using clang 3.5.0 1262 or higher. 1263 126420181211: 1265 Remove the timed and netdate programs from the base tree. Setting 1266 the time with these daemons has been obsolete for over a decade. 1267 126820181126: 1269 On amd64, arm64 and armv7 (architectures that install LLVM's ld.lld 1270 linker as /usr/bin/ld) GNU ld is no longer installed as ld.bfd, as 1271 it produces broken binaries when ifuncs are in use. Users needing 1272 GNU ld should install the binutils port or package. 1273 127420181123: 1275 The BSD crtbegin and crtend code has been enabled by default. It has 1276 had extensive testing on amd64, arm64, and i386. It can be disabled 1277 by building a world with -DWITHOUT_BSD_CRTBEGIN. 1278 127920181115: 1280 The set of CTM commands (ctm, ctm_smail, ctm_rmail, ctm_dequeue) 1281 has been converted to a port (misc/ctm) and will be removed from 1282 FreeBSD-13. It is available as a package (ctm) for all supported 1283 FreeBSD versions. 1284 128520181110: 1286 The default newsyslog.conf(5) file has been changed to only include 1287 files in /etc/newsyslog.conf.d/ and /usr/local/etc/newsyslog.conf.d/ if 1288 the filenames end in '.conf' and do not begin with a '.'. 1289 1290 You should check the configuration files in these two directories match 1291 this naming convention. You can verify which configuration files are 1292 being included using the command: 1293 $ newsyslog -Nrv 1294 129520181019: 1296 Stable/12 was branched created. 1297 129820181015: 1299 Ports for the DRM modules have been simplified. Now, amd64 users should 1300 just install the drm-kmod port. All others should install 1301 drm-legacy-kmod. 1302 1303 Graphics hardware that's newer than about 2010 usually works with 1304 drm-kmod. For hardware older than 2013, however, some users will need 1305 to use drm-legacy-kmod if drm-kmod doesn't work for them. Hardware older 1306 than 2008 usually only works in drm-legacy-kmod. The graphics team can 1307 only commit to hardware made since 2013 due to the complexity of the 1308 market and difficulty to test all the older cards effectively. If you 1309 have hardware supported by drm-kmod, you are strongly encouraged to use 1310 that as you will get better support. 1311 1312 Other than KPI chasing, drm-legacy-kmod will not be updated. As outlined 1313 elsewhere, the drm and drm2 modules will be eliminated from the src base 1314 soon (with a limited exception for arm). Please update to the package 1315 asap and report any issues to x11@freebsd.org. 1316 1317 Generally, anybody using the drm*-kmod packages should add 1318 WITHOUT_DRM_MODULE=t and WITHOUT_DRM2_MODULE=t to avoid nasty 1319 cross-threading surprises, especially with automatic driver 1320 loading from X11 startup. These will become the defaults in 13-current 1321 shortly. 1322 132320181012: 1324 The ixlv(4) driver has been renamed to iavf(4). As a consequence, 1325 custom kernel and module loading configuration files must be updated 1326 accordingly. Moreover, interfaces previous presented as ixlvN to the 1327 system are now exposed as iavfN and network configuration files must 1328 be adjusted as necessary. 1329 133020181009: 1331 OpenSSL has been updated to version 1.1.1. This update included 1332 additional various API changes throughout the base system. It is 1333 important to rebuild third-party software after upgrading. The value 1334 of __FreeBSD_version has been bumped accordingly. 1335 133620181006: 1337 The legacy DRM modules and drivers have now been added to the loader's 1338 module blacklist, in favor of loading them with kld_list in rc.conf(5). 1339 The module blacklist may be overridden with the loader.conf(5) 1340 'module_blacklist' variable, but loading them via rc.conf(5) is strongly 1341 encouraged. 1342 134320181002: 1344 The cam(4) based nda(4) driver will be used over nvd(4) by default on 1345 powerpc64. You may set 'options NVME_USE_NVD=1' in your kernel conf or 1346 loader tunable 'hw.nvme.use_nvd=1' if you wish to use the existing 1347 driver. Make sure to edit /boot/etc/kboot.conf and fstab to use the 1348 nda device name. 1349 135020180913: 1351 Reproducible build mode is now on by default, in preparation for 1352 FreeBSD 12.0. This eliminates build metadata such as the user, 1353 host, and time from the kernel (and uname), unless the working tree 1354 corresponds to a modified checkout from a version control system. 1355 The previous behavior can be obtained by setting the /etc/src.conf 1356 knob WITHOUT_REPRODUCIBLE_BUILD. 1357 135820180826: 1359 The Yarrow CSPRNG has been removed from the kernel as it has not been 1360 supported by its designers since at least 2003. Fortuna has been the 1361 default since FreeBSD-11. 1362 136320180822: 1364 devctl freeze/thaw have gone into the tree, the rc scripts have been 1365 updated to use them and devmatch has been changed. You should update 1366 kernel, userland and rc scripts all at the same time. 1367 136820180818: 1369 The default interpreter has been switched from 4th to Lua. 1370 LOADER_DEFAULT_INTERP, documented in build(7), will override the default 1371 interpreter. If you have custom FORTH code you will need to set 1372 LOADER_DEFAULT_INTERP=4th (valid values are 4th, lua or simp) in 1373 src.conf for the build. This will create default hard links between 1374 loader and loader_4th instead of loader and loader_lua, the new default. 1375 If you are using UEFI it will create the proper hard link to loader.efi. 1376 1377 bhyve uses userboot.so. It remains 4th-only until some issues are solved 1378 regarding coexisting with multiple versions of FreeBSD are resolved. 1379 138020180815: 1381 ls(1) now respects the COLORTERM environment variable used in other 1382 systems and software to indicate that a colored terminal is both 1383 supported and desired. If ls(1) is suddenly emitting colors, they may 1384 be disabled again by either removing the unwanted COLORTERM from your 1385 environment, or using `ls --color=never`. The ls(1) specific CLICOLOR 1386 may not be observed in a future release. 1387 138820180808: 1389 The default pager for most commands has been changed to "less". To 1390 restore the old behavior, set PAGER="more" and MANPAGER="more -s" in 1391 your environment. 1392 139320180731: 1394 The jedec_ts(4) driver has been removed. A superset of its functionality 1395 is available in the jedec_dimm(4) driver, and the manpage for that 1396 driver includes migration instructions. If you have "device jedec_ts" 1397 in your kernel configuration file, it must be removed. 1398 139920180730: 1400 amd64/GENERIC now has EFI runtime services, EFIRT, enabled by default. 1401 This should have no effect if the kernel is booted via BIOS/legacy boot. 1402 EFIRT may be disabled via a loader tunable, efi.rt.disabled, if a system 1403 has a buggy firmware that prevents a successful boot due to use of 1404 runtime services. 1405 140620180727: 1407 Atmel AT91RM9200 and AT91SAM9, Cavium CNS 11xx and XScale 1408 support has been removed from the tree. These ports were 1409 obsolete and/or known to be broken for many years. 1410 141120180723: 1412 loader.efi has been augmented to participate more fully in the 1413 UEFI boot manager protocol. loader.efi will now look at the 1414 BootXXXX environment variable to determine if a specific kernel 1415 or root partition was specified. XXXX is derived from BootCurrent. 1416 efibootmgr(8) manages these standard UEFI variables. 1417 141820180720: 1419 zfsloader's functionality has now been folded into loader. 1420 zfsloader is no longer necessary once you've updated your 1421 boot blocks. For a transition period, we will install a 1422 hardlink for zfsloader to loader to allow a smooth transition 1423 until the boot blocks can be updated (hard link because old 1424 zfs boot blocks don't understand symlinks). 1425 142620180719: 1427 ARM64 now have efifb support, if you want to have serial console 1428 on your arm64 board when an screen is connected and the bootloader 1429 setup a frame buffer for us to use, just add : 1430 boot_serial=YES 1431 boot_multicons=YES 1432 in /boot/loader.conf 1433 For Raspberry Pi 3 (RPI) users, this is needed even if you don't have 1434 an screen connected as the firmware will setup a frame buffer are that 1435 u-boot will expose as an EFI frame buffer. 1436 143720180719: 1438 New uid:gid added, ntpd:ntpd (123:123). Be sure to run mergemaster 1439 or take steps to update /etc/passwd before doing installworld on 1440 existing systems. Do not skip the "mergemaster -Fp" step before 1441 installworld, as described in the update procedures near the bottom 1442 of this document. Also, rc.d/ntpd now starts ntpd(8) as user ntpd 1443 if the new mac_ntpd(4) policy is available, unless ntpd_flags or 1444 the ntp config file contain options that change file/dir locations. 1445 When such options (e.g., "statsdir" or "crypto") are used, ntpd can 1446 still be run as non-root by setting ntpd_user=ntpd in rc.conf, after 1447 taking steps to ensure that all required files/dirs are accessible 1448 by the ntpd user. 1449 145020180717: 1451 Big endian arm support has been removed. 1452 145320180711: 1454 The static environment setup in kernel configs is no longer mutually 1455 exclusive with the loader(8) environment by default. In order to 1456 restore the previous default behavior of disabling the loader(8) 1457 environment if a static environment is present, you must specify 1458 loader_env.disabled=1 in the static environment. 1459 146020180705: 1461 The ABI of syscalls used by management tools like sockstat and 1462 netstat has been broken to allow 32-bit binaries to work on 1463 64-bit kernels without modification. These programs will need 1464 to match the kernel in order to function. External programs may 1465 require minor modifications to accommodate a change of type in 1466 structures from pointers to 64-bit virtual addresses. 1467 146820180702: 1469 On i386 and amd64 atomics are now inlined. Out of tree modules using 1470 atomics will need to be rebuilt. 1471 147220180701: 1473 The '%I' format in the kern.corefile sysctl limits the number of 1474 core files that a process can generate to the number stored in the 1475 debug.ncores sysctl. The '%I' format is replaced by the single digit 1476 index. Previously, if all indexes were taken the kernel would overwrite 1477 only a core file with the highest index in a filename. 1478 Currently the system will create a new core file if there is a free 1479 index or if all slots are taken it will overwrite the oldest one. 1480 148120180630: 1482 Clang, llvm, lld, lldb, compiler-rt and libc++ have been upgraded to 1483 6.0.1. Please see the 20141231 entry below for information about 1484 prerequisites and upgrading, if you are not already using clang 3.5.0 1485 or higher. 1486 148720180628: 1488 r335753 introduced a new quoting method. However, etc/devd/devmatch.conf 1489 needed to be changed to work with it. This change was made with r335763 1490 and requires a mergemaster / etcupdate / etc to update the installed 1491 file. 1492 149320180612: 1494 r334930 changed the interface between the NFS modules, so they all 1495 need to be rebuilt. r335018 did a __FreeBSD_version bump for this. 1496 149720180530: 1498 As of r334391 lld is the default amd64 system linker; it is installed 1499 as /usr/bin/ld. Kernel build workarounds (see 20180510 entry) are no 1500 longer necessary. 1501 150220180530: 1503 The kernel / userland interface for devinfo changed, so you'll 1504 need a new kernel and userland as a pair for it to work (rebuilding 1505 lib/libdevinfo is all that's required). devinfo and devmatch will 1506 not work, but everything else will when there's a mismatch. 1507 150820180523: 1509 The on-disk format for hwpmc callchain records has changed to include 1510 threadid corresponding to a given record. This changes the field offsets 1511 and thus requires that libpmcstat be rebuilt before using a kernel 1512 later than r334108. 1513 151420180517: 1515 The vxge(4) driver has been removed. This driver was introduced into 1516 HEAD one week before the Exar left the Ethernet market and is not 1517 known to be used. If you have device vxge in your kernel config file 1518 it must be removed. 1519 152020180510: 1521 The amd64 kernel now requires a ld that supports ifunc to produce a 1522 working kernel, either lld or a newer binutils. lld is built by default 1523 on amd64, and the 'buildkernel' target uses it automatically. However, 1524 it is not the default linker, so building the kernel the traditional 1525 way requires LD=ld.lld on the command line (or LD=/usr/local/bin/ld for 1526 binutils port/package). lld will soon be default, and this requirement 1527 will go away. 1528 1529 NOTE: As of r334391 lld is the default system linker on amd64, and no 1530 workaround is necessary. 1531 153220180508: 1533 The nxge(4) driver has been removed. This driver was for PCI-X 10g 1534 cards made by s2io/Neterion. The company was acquired by Exar and 1535 no longer sells or supports Ethernet products. If you have device 1536 nxge in your kernel config file it must be removed. 1537 153820180504: 1539 The tz database (tzdb) has been updated to 2018e. This version more 1540 correctly models time stamps in time zones with negative DST such as 1541 Europe/Dublin (from 1971 on), Europe/Prague (1946/7), and 1542 Africa/Windhoek (1994/2017). This does not affect the UT offsets, only 1543 time zone abbreviations and the tm_isdst flag. 1544 154520180502: 1546 The ixgb(4) driver has been removed. This driver was for an early and 1547 uncommon legacy PCI 10GbE for a single ASIC, Intel 82597EX. Intel 1548 quickly shifted to the long lived ixgbe family. If you have device 1549 ixgb in your kernel config file it must be removed. 1550 155120180501: 1552 The lmc(4) driver has been removed. This was a WAN interface 1553 card that was already reportedly rare in 2003, and had an ambiguous 1554 license. If you have device lmc in your kernel config file it must 1555 be removed. 1556 155720180413: 1558 Support for Arcnet networks has been removed. If you have device 1559 arcnet or device cm in your kernel config file they must be 1560 removed. 1561 156220180411: 1563 Support for FDDI networks has been removed. If you have device 1564 fddi or device fpa in your kernel config file they must be 1565 removed. 1566 156720180406: 1568 In addition to supporting RFC 3164 formatted messages, the 1569 syslogd(8) service is now capable of parsing RFC 5424 formatted 1570 log messages. The main benefit of using RFC 5424 is that clients 1571 may now send log messages with timestamps containing year numbers, 1572 microseconds and time zone offsets. 1573 1574 Similarly, the syslog(3) C library function has been altered to 1575 send RFC 5424 formatted messages to the local system logging 1576 daemon. On systems using syslogd(8), this change should have no 1577 negative impact, as long as syslogd(8) and the C library are 1578 updated at the same time. On systems using a different system 1579 logging daemon, it may be necessary to make configuration 1580 adjustments, depending on the software used. 1581 1582 When using syslog-ng, add the 'syslog-protocol' flag to local 1583 input sources to enable parsing of RFC 5424 formatted messages: 1584 1585 source src { 1586 unix-dgram("/var/run/log" flags(syslog-protocol)); 1587 } 1588 1589 When using rsyslog, disable the 'SysSock.UseSpecialParser' option 1590 of the 'imuxsock' module to let messages be processed by the 1591 regular RFC 3164/5424 parsing pipeline: 1592 1593 module(load="imuxsock" SysSock.UseSpecialParser="off") 1594 1595 Do note that these changes only affect communication between local 1596 applications and syslogd(8). The format that syslogd(8) uses to 1597 store messages on disk or forward messages to other systems 1598 remains unchanged. syslogd(8) still uses RFC 3164 for these 1599 purposes. Options to customize this behaviour will be added in the 1600 future. Utilities that process log files stored in /var/log are 1601 thus expected to continue to function as before. 1602 1603 __FreeBSD_version has been incremented to 1200061 to denote this 1604 change. 1605 160620180328: 1607 Support for token ring networks has been removed. If you 1608 have "device token" in your kernel config you should remove 1609 it. No device drivers supported token ring. 1610 161120180323: 1612 makefs was modified to be able to tag ISO9660 El Torito boot catalog 1613 entries as EFI instead of overloading the i386 tag as done previously. 1614 The amd64 mkisoimages.sh script used to build amd64 ISO images for 1615 release was updated to use this. This may mean that makefs must be 1616 updated before "make cdrom" can be run in the release directory. This 1617 should be as simple as: 1618 1619 $ cd $SRCDIR/usr.sbin/makefs 1620 $ make depend all install 1621 162220180212: 1623 FreeBSD boot loader enhanced with Lua scripting. It's purely opt-in for 1624 now by building WITH_LOADER_LUA and WITHOUT_FORTH in /etc/src.conf. 1625 Co-existence for the transition period will come shortly. Booting is a 1626 complex environment and test coverage for Lua-enabled loaders has been 1627 thin, so it would be prudent to assume it might not work and make 1628 provisions for backup boot methods. 1629 163020180211: 1631 devmatch functionality has been turned on in devd. It will automatically 1632 load drivers for unattached devices. This may cause unexpected drivers 1633 to be loaded. Please report any problems to current@ and 1634 imp@freebsd.org. 1635 163620180114: 1637 Clang, llvm, lld, lldb, compiler-rt and libc++ have been upgraded to 1638 6.0.0. Please see the 20141231 entry below for information about 1639 prerequisites and upgrading, if you are not already using clang 3.5.0 1640 or higher. 1641 164220180110: 1643 LLVM's lld linker is now used as the FreeBSD/amd64 bootstrap linker. 1644 This means it is used to link the kernel and userland libraries and 1645 executables, but is not yet installed as /usr/bin/ld by default. 1646 1647 To revert to ld.bfd as the bootstrap linker, in /etc/src.conf set 1648 WITHOUT_LLD_BOOTSTRAP=yes 1649 165020180110: 1651 On i386, pmtimer has been removed. Its functionality has been folded 1652 into apm. It was a no-op on ACPI in current for a while now (but was 1653 still needed on i386 in FreeBSD 11 and earlier). Users may need to 1654 remove it from kernel config files. 1655 165620180104: 1657 The use of RSS hash from the network card aka flowid has been 1658 disabled by default for lagg(4) as it's currently incompatible with 1659 the lacp and loadbalance protocols. 1660 1661 This can be re-enabled by setting the following in loader.conf: 1662 net.link.lagg.default_use_flowid="1" 1663 166420180102: 1665 The SW_WATCHDOG option is no longer necessary to enable the 1666 hardclock-based software watchdog if no hardware watchdog is 1667 configured. As before, SW_WATCHDOG will cause the software 1668 watchdog to be enabled even if a hardware watchdog is configured. 1669 167020171215: 1671 r326887 fixes the issue described in the 20171214 UPDATING entry. 1672 r326888 flips the switch back to building GELI support always. 1673 167420171214: 1675 r362593 broke ZFS + GELI support for reasons unknown. However, 1676 it also broke ZFS support generally, so GELI has been turned off 1677 by default as the lesser evil in r326857. If you boot off ZFS and/or 1678 GELI, it might not be a good time to update. 1679 168020171125: 1681 PowerPC users must update loader(8) by rebuilding world before 1682 installing a new kernel, as the protocol connecting them has 1683 changed. Without the update, loader metadata will not be passed 1684 successfully to the kernel and users will have to enter their 1685 root partition at the kernel mountroot prompt to continue booting. 1686 Newer versions of loader can boot old kernels without issue. 1687 168820171110: 1689 The LOADER_FIREWIRE_SUPPORT build variable has been renamed to 1690 WITH/OUT_LOADER_FIREWIRE. LOADER_{NO_,}GELI_SUPPORT has been renamed 1691 to WITH/OUT_LOADER_GELI. 1692 169320171106: 1694 The naive and non-compliant support of posix_fallocate(2) in ZFS 1695 has been removed as of r325320. The system call now returns EINVAL 1696 when used on a ZFS file. Although the new behavior complies with the 1697 standard, some consumers are not prepared to cope with it. 1698 One known victim is lld prior to r325420. 1699 170020171102: 1701 Building in a FreeBSD src checkout will automatically create object 1702 directories now rather than store files in the current directory if 1703 'make obj' was not ran. Calling 'make obj' is no longer necessary. 1704 This feature can be disabled by setting WITHOUT_AUTO_OBJ=yes in 1705 /etc/src-env.conf (not /etc/src.conf), or passing the option in the 1706 environment. 1707 170820171101: 1709 The default MAKEOBJDIR has changed from /usr/obj/<srcdir> for native 1710 builds, and /usr/obj/<arch>/<srcdir> for cross-builds, to a unified 1711 /usr/obj/<srcdir>/<arch>. This behavior can be changed to the old 1712 format by setting WITHOUT_UNIFIED_OBJDIR=yes in /etc/src-env.conf, 1713 the environment, or with -DWITHOUT_UNIFIED_OBJDIR when building. 1714 The UNIFIED_OBJDIR option is a transitional feature that will be 1715 removed for 12.0 release; please migrate to the new format for any 1716 tools by looking up the OBJDIR used by 'make -V .OBJDIR' means rather 1717 than hardcoding paths. 1718 171920171028: 1720 The native-xtools target no longer installs the files by default to the 1721 OBJDIR. Use the native-xtools-install target with a DESTDIR to install 1722 to ${DESTDIR}/${NXTP} where NXTP defaults to /nxb-bin. 1723 172420171021: 1725 As part of the boot loader infrastructure cleanup, LOADER_*_SUPPORT 1726 options are changing from controlling the build if defined / undefined 1727 to controlling the build with explicit 'yes' or 'no' values. They will 1728 shift to WITH/WITHOUT options to match other options in the system. 1729 173020171010: 1731 libstand has turned into a private library for sys/boot use only. 1732 It is no longer supported as a public interface outside of sys/boot. 1733 173420171005: 1735 The arm port has split armv6 into armv6 and armv7. armv7 is now 1736 a valid TARGET_ARCH/MACHINE_ARCH setting. If you have an armv7 system 1737 and are running a kernel from before r324363, you will need to add 1738 MACHINE_ARCH=armv7 to 'make buildworld' to do a native build. 1739 174020171003: 1741 When building multiple kernels using KERNCONF, non-existent KERNCONF 1742 files will produce an error and buildkernel will fail. Previously 1743 missing KERNCONF files silently failed giving no indication as to 1744 why, only to subsequently discover during installkernel that the 1745 desired kernel was never built in the first place. 1746 174720170912: 1748 The default serial number format for CTL LUNs has changed. This will 1749 affect users who use /dev/diskid/* device nodes, or whose FibreChannel 1750 or iSCSI clients care about their LUNs' serial numbers. Users who 1751 require serial number stability should hardcode serial numbers in 1752 /etc/ctl.conf . 1753 175420170912: 1755 For 32-bit arm compiled for hard-float support, soft-floating point 1756 binaries now always get their shared libraries from 1757 LD_SOFT_LIBRARY_PATH (in the past, this was only used if 1758 /usr/libsoft also existed). Only users with a hard-float ld.so, but 1759 soft-float everything else should be affected. 1760 176120170826: 1762 The geli password typed at boot is now hidden. To restore the previous 1763 behavior, see geli(8) for configuration options. 1764 176520170825: 1766 Move PMTUD blackhole counters to TCPSTATS and remove them from bare 1767 sysctl values. Minor nit, but requires a rebuild of both world/kernel 1768 to complete. 1769 177020170814: 1771 "make check" behavior (made in ^/head@r295380) has been changed to 1772 execute from a limited sandbox, as opposed to executing from 1773 ${TESTSDIR}. 1774 1775 Behavioral changes: 1776 - The "beforecheck" and "aftercheck" targets are now specified. 1777 - ${CHECKDIR} (added in commit noted above) has been removed. 1778 - Legacy behavior can be enabled by setting 1779 WITHOUT_MAKE_CHECK_USE_SANDBOX in src.conf(5) or the environment. 1780 1781 If the limited sandbox mode is enabled, "make check" will execute 1782 "make distribution", then install, execute the tests, and clean up the 1783 sandbox if successful. 1784 1785 The "make distribution" and "make install" targets are typically run as 1786 root to set appropriate permissions and ownership at installation time. 1787 The end-user should set "WITH_INSTALL_AS_USER" in src.conf(5) or the 1788 environment if executing "make check" with limited sandbox mode using 1789 an unprivileged user. 1790 179120170808: 1792 Since the switch to GPT disk labels, fsck for UFS/FFS has been 1793 unable to automatically find alternate superblocks. As of r322297, 1794 the information needed to find alternate superblocks has been 1795 moved to the end of the area reserved for the boot block. 1796 Filesystems created with a newfs of this vintage or later 1797 will create the recovery information. If you have a filesystem 1798 created prior to this change and wish to have a recovery block 1799 created for your filesystem, you can do so by running fsck in 1800 foreground mode (i.e., do not use the -p or -y options). As it 1801 starts, fsck will ask ``SAVE DATA TO FIND ALTERNATE SUPERBLOCKS'' 1802 to which you should answer yes. 1803 180420170728: 1805 As of r321665, an NFSv4 server configuration that services 1806 Kerberos mounts or clients that do not support the uid/gid in 1807 owner/owner_group string capability, must explicitly enable 1808 the nfsuserd daemon by adding nfsuserd_enable="YES" to the 1809 machine's /etc/rc.conf file. 1810 181120170722: 1812 Clang, llvm, lldb, compiler-rt and libc++ have been upgraded to 5.0.0. 1813 Please see the 20141231 entry below for information about prerequisites 1814 and upgrading, if you are not already using clang 3.5.0 or higher. 1815 181620170701: 1817 WITHOUT_RCMDS is now the default. Set WITH_RCMDS if you need the 1818 r-commands (rlogin, rsh, etc.) to be built with the base system. 1819 182020170625: 1821 The FreeBSD/powerpc platform now uses a 64-bit type for time_t. This is 1822 a very major ABI incompatible change, so users of FreeBSD/powerpc must 1823 be careful when performing source upgrades. It is best to run 1824 'make installworld' from an alternate root system, either a live 1825 CD/memory stick, or a temporary root partition. Additionally, all ports 1826 must be recompiled. powerpc64 is largely unaffected, except in the case 1827 of 32-bit compatibility. All 32-bit binaries will be affected. 1828 182920170623: 1830 Forward compatibility for the "ino64" project have been committed. This 1831 will allow most new binaries to run on older kernels in a limited 1832 fashion. This prevents many of the common foot-shooting actions in the 1833 upgrade as well as the limited ability to roll back the kernel across 1834 the ino64 upgrade. Complicated use cases may not work properly, though 1835 enough simpler ones work to allow recovery in most situations. 1836 183720170620: 1838 Switch back to the BSDL dtc (Device Tree Compiler). Set WITH_GPL_DTC 1839 if you require the GPL compiler. 1840 184120170619: 1842 Forward compatibility for the "ino64" project have been committed. This 1843 will allow most new binaries to run on older kernels in a limited 1844 fashion. This prevents many of the common foot-shooting actions in the 1845 upgrade as well as the limited ability to roll back the kernel across 1846 the ino64 upgrade. Complicated use cases may not work properly, though 1847 enough simpler ones work to allow recovery in most situations. 1848 184920170618: 1850 The internal ABI used for communication between the NFS kernel modules 1851 was changed by r320085, so __FreeBSD_version was bumped to 1852 ensure all the NFS related modules are updated together. 1853 185420170617: 1855 The ABI of struct event was changed by extending the data 1856 member to 64bit and adding ext fields. For upgrade, same 1857 precautions as for the entry 20170523 "ino64" must be 1858 followed. 1859 186020170531: 1861 The GNU roff toolchain has been removed from base. To render manpages 1862 which are not supported by mandoc(1), man(1) can fallback on GNU roff 1863 from ports (and recommends to install it). 1864 To render roff(7) documents, consider using GNU roff from ports or the 1865 heirloom doctools roff toolchain from ports via pkg install groff or 1866 via pkg install heirloom-doctools. 1867 186820170524: 1869 The ath(4) and ath_hal(4) modules now build piecemeal to allow for 1870 smaller runtime footprint builds. This is useful for embedded systems 1871 which only require one chipset support. 1872 1873 If you load it as a module, make sure this is in /boot/loader.conf: 1874 1875 if_ath_load="YES" 1876 1877 This will load the HAL, all chip/RF backends and if_ath_pci. 1878 If you have if_ath_pci in /boot/loader.conf, ensure it is after 1879 if_ath or it will not load any HAL chipset support. 1880 1881 If you want to selectively load things (eg on cheaper ARM/MIPS 1882 platforms where RAM is at a premium) you should: 1883 1884 * load ath_hal 1885 * load the chip modules in question 1886 * load ath_rate, ath_dfs 1887 * load ath_main 1888 * load if_ath_pci and/or if_ath_ahb depending upon your particular 1889 bus bind type - this is where probe/attach is done. 1890 1891 For further comments/feedback, poke adrian@ . 1892 189320170523: 1894 The "ino64" 64-bit inode project has been committed, which extends 1895 a number of types to 64 bits. Upgrading in place requires care and 1896 adherence to the documented upgrade procedure. 1897 1898 If using a custom kernel configuration ensure that the 1899 COMPAT_FREEBSD11 option is included (as during the upgrade the 1900 system will be running the ino64 kernel with the existing world). 1901 1902 For the safest in-place upgrade begin by removing previous build 1903 artifacts via "rm -rf /usr/obj/*". Then, carefully follow the full 1904 procedure documented below under the heading "To rebuild everything and 1905 install it on the current system." Specifically, a reboot is required 1906 after installing the new kernel before installing world. While an 1907 installworld normally works by accident from multiuser after rebooting 1908 the proper kernel, there are many cases where this will fail across this 1909 upgrade and installworld from single user is required. 1910 191120170424: 1912 The NATM framework including the en(4), fatm(4), hatm(4), and 1913 patm(4) devices has been removed. Consumers should plan a 1914 migration before the end-of-life date for FreeBSD 11. 1915 191620170420: 1917 GNU diff has been replaced by a BSD licensed diff. Some features of GNU 1918 diff has not been implemented, if those are needed a newer version of 1919 GNU diff is available via the diffutils package under the gdiff name. 1920 192120170413: 1922 As of r316810 for ipfilter, keep frags is no longer assumed when 1923 keep state is specified in a rule. r316810 aligns ipfilter with 1924 documentation in man pages separating keep frags from keep state. 1925 This allows keep state to be specified without forcing keep frags 1926 and allows keep frags to be specified independently of keep state. 1927 To maintain previous behaviour, also specify keep frags with 1928 keep state (as documented in ipf.conf.5). 1929 193020170407: 1931 arm64 builds now use the base system LLD 4.0.0 linker by default, 1932 instead of requiring that the aarch64-binutils port or package be 1933 installed. To continue using aarch64-binutils, set 1934 CROSS_BINUTILS_PREFIX=/usr/local/aarch64-freebsd/bin . 1935 193620170405: 1937 The UDP optimization in entry 20160818 that added the sysctl 1938 net.inet.udp.require_l2_bcast has been reverted. L2 broadcast 1939 packets will no longer be treated as L3 broadcast packets. 1940 194120170331: 1942 Binds and sends to the loopback addresses, IPv6 and IPv4, will now 1943 use any explicitly assigned loopback address available in the jail 1944 instead of using the first assigned address of the jail. 1945 194620170329: 1947 The ctl.ko module no longer implements the iSCSI target frontend: 1948 cfiscsi.ko does instead. 1949 1950 If building cfiscsi.ko as a kernel module, the module can be loaded 1951 via one of the following methods: 1952 - `cfiscsi_load="YES"` in loader.conf(5). 1953 - Add `cfiscsi` to `$kld_list` in rc.conf(5). 1954 - ctladm(8)/ctld(8), when compiled with iSCSI support 1955 (`WITH_ISCSI=yes` in src.conf(5)) 1956 1957 Please see cfiscsi(4) for more details. 1958 195920170316: 1960 The mmcsd.ko module now additionally depends on geom_flashmap.ko. 1961 Also, mmc.ko and mmcsd.ko need to be a matching pair built from the 1962 same source (previously, the dependency of mmcsd.ko on mmc.ko was 1963 missing, but mmcsd.ko now will refuse to load if it is incompatible 1964 with mmc.ko). 1965 196620170315: 1967 The syntax of ipfw(8) named states was changed to avoid ambiguity. 1968 If you have used named states in the firewall rules, you need to modify 1969 them after installworld and before rebooting. Now named states must 1970 be prefixed with colon. 1971 197220170311: 1973 The old drm (sys/dev/drm/) drivers for i915 and radeon have been 1974 removed as the userland we provide cannot use them. The KMS version 1975 (sys/dev/drm2) supports the same hardware. 1976 197720170302: 1978 Clang, llvm, lldb, compiler-rt and libc++ have been upgraded to 4.0.0. 1979 Please see the 20141231 entry below for information about prerequisites 1980 and upgrading, if you are not already using clang 3.5.0 or higher. 1981 198220170221: 1983 The code that provides support for ZFS .zfs/ directory functionality 1984 has been reimplemented. It's not possible now to create a snapshot 1985 by mkdir under .zfs/snapshot/. That should be the only user visible 1986 change. 1987 198820170216: 1989 EISA bus support has been removed. The WITH_EISA option is no longer 1990 valid. 1991 199220170215: 1993 MCA bus support has been removed. 1994 199520170127: 1996 The WITH_LLD_AS_LD / WITHOUT_LLD_AS_LD build knobs have been renamed 1997 WITH_LLD_IS_LD / WITHOUT_LLD_IS_LD, for consistency with CLANG_IS_CC. 1998 199920170112: 2000 The EM_MULTIQUEUE kernel configuration option is deprecated now that 2001 the em(4) driver conforms to iflib specifications. 2002 200320170109: 2004 The igb(4), em(4) and lem(4) ethernet drivers are now implemented via 2005 IFLIB. If you have a custom kernel configuration that excludes em(4) 2006 but you use igb(4), you need to re-add em(4) to your custom 2007 configuration. 2008 200920161217: 2010 Clang, llvm, lldb, compiler-rt and libc++ have been upgraded to 3.9.1. 2011 Please see the 20141231 entry below for information about prerequisites 2012 and upgrading, if you are not already using clang 3.5.0 or higher. 2013 201420161124: 2015 Clang, llvm, lldb, compiler-rt and libc++ have been upgraded to 3.9.0. 2016 Please see the 20141231 entry below for information about prerequisites 2017 and upgrading, if you are not already using clang 3.5.0 or higher. 2018 201920161119: 2020 The layout of the pmap structure has changed for powerpc to put the pmap 2021 statistics at the front for all CPU variations. libkvm(3) and all tools 2022 that link against it need to be recompiled. 2023 202420161030: 2025 isl(4) and cyapa(4) drivers now require a new driver, 2026 chromebook_platform(4), to work properly on Chromebook-class hardware. 2027 On other types of hardware the drivers may need to be configured using 2028 device hints. Please see the corresponding manual pages for details. 2029 203020161017: 2031 The urtwn(4) driver was merged into rtwn(4) and now consists of 2032 rtwn(4) main module + rtwn_usb(4) and rtwn_pci(4) bus-specific 2033 parts. 2034 Also, firmware for RTL8188CE was renamed due to possible name 2035 conflict (rtwnrtl8192cU(B) -> rtwnrtl8192cE(B)) 2036 203720161015: 2038 GNU rcs has been removed from base. It is available as packages: 2039 - rcs: Latest GPLv3 GNU rcs version. 2040 - rcs57: Copy of the latest version of GNU rcs (GPLv2) before it was 2041 removed from base. 2042 204320161008: 2044 Use of the cc_cdg, cc_chd, cc_hd, or cc_vegas congestion control 2045 modules now requires that the kernel configuration contain the 2046 TCP_HHOOK option. (This option is included in the GENERIC kernel.) 2047 204820161003: 2049 The WITHOUT_ELFCOPY_AS_OBJCOPY src.conf(5) knob has been retired. 2050 ELF Tool Chain's elfcopy is always installed as /usr/bin/objcopy. 2051 205220160924: 2053 Relocatable object files with the extension of .So have been renamed 2054 to use an extension of .pico instead. The purpose of this change is 2055 to avoid a name clash with shared libraries on case-insensitive file 2056 systems. On those file systems, foo.So is the same file as foo.so. 2057 205820160918: 2059 GNU rcs has been turned off by default. It can (temporarily) be built 2060 again by adding WITH_RCS knob in src.conf. 2061 Otherwise, GNU rcs is available from packages: 2062 - rcs: Latest GPLv3 GNU rcs version. 2063 - rcs57: Copy of the latest version of GNU rcs (GPLv2) from base. 2064 206520160918: 2066 The backup_uses_rcs functionality has been removed from rc.subr. 2067 206820160908: 2069 The queue(3) debugging macro, QUEUE_MACRO_DEBUG, has been split into 2070 two separate components, QUEUE_MACRO_DEBUG_TRACE and 2071 QUEUE_MACRO_DEBUG_TRASH. Define both for the original 2072 QUEUE_MACRO_DEBUG behavior. 2073 207420160824: 2075 r304787 changed some ioctl interfaces between the iSCSI userspace 2076 programs and the kernel. ctladm, ctld, iscsictl, and iscsid must be 2077 rebuilt to work with new kernels. __FreeBSD_version has been bumped 2078 to 1200005. 2079 208020160818: 2081 The UDP receive code has been updated to only treat incoming UDP 2082 packets that were addressed to an L2 broadcast address as L3 2083 broadcast packets. It is not expected that this will affect any 2084 standards-conforming UDP application. The new behaviour can be 2085 disabled by setting the sysctl net.inet.udp.require_l2_bcast to 2086 0. 2087 208820160818: 2089 Remove the openbsd_poll system call. 2090 __FreeBSD_version has been bumped because of this. 2091 209220160708: 2093 The stable/11 branch has been created from head@r302406. 2094 2095After branch N is created, entries older than the N-2 branch point are removed 2096from this file. After stable/14 is branched and current becomes FreeBSD 15, 2097entries older than stable/12 branch point will be removed from current's 2098UPDATING file. 2099 2100COMMON ITEMS: 2101 2102 General Notes 2103 ------------- 2104 Sometimes, obscure build problems are the result of environment 2105 poisoning. This can happen because the make utility reads its 2106 environment when searching for values for global variables. To run 2107 your build attempts in an "environmental clean room", prefix all make 2108 commands with 'env -i '. See the env(1) manual page for more details. 2109 Occasionally a build failure will occur with "make -j" due to a race 2110 condition. If this happens try building again without -j, and please 2111 report a bug if it happens consistently. 2112 2113 When upgrading from one major version to another it is generally best to 2114 upgrade to the latest code in the currently installed branch first, then 2115 do an upgrade to the new branch. This is the best-tested upgrade path, 2116 and has the highest probability of being successful. Please try this 2117 approach if you encounter problems with a major version upgrade. Since 2118 the stable 4.x branch point, one has generally been able to upgrade from 2119 anywhere in the most recent stable branch to head / current (or even the 2120 last couple of stable branches). See the top of this file when there's 2121 an exception. 2122 2123 The update process will emit an error on an attempt to perform a build 2124 or install from a FreeBSD version below the earliest supported version. 2125 When updating from an older version the update should be performed one 2126 major release at a time, including running `make delete-old` at each 2127 step. 2128 2129 When upgrading a live system, having a root shell around before 2130 installing anything can help undo problems. Not having a root shell 2131 around can lead to problems if pam has changed too much from your 2132 starting point to allow continued authentication after the upgrade. 2133 2134 This file should be read as a log of events. When a later event changes 2135 information of a prior event, the prior event should not be deleted. 2136 Instead, a pointer to the entry with the new information should be 2137 placed in the old entry. Readers of this file should also sanity check 2138 older entries before relying on them blindly. Authors of new entries 2139 should write them with this in mind. 2140 2141 ZFS notes 2142 --------- 2143 When upgrading the boot ZFS pool to a new version (via zpool upgrade), 2144 always follow these three steps: 2145 2146 1) recompile and reinstall the ZFS boot loader and boot block 2147 (this is part of "make buildworld" and "make installworld") 2148 2149 2) update the ZFS boot block on your boot drive (only required when 2150 doing a zpool upgrade): 2151 2152 When booting on x86 via BIOS, use the following to update the ZFS boot 2153 block on the freebsd-boot partition of a GPT partitioned drive ada0: 2154 gpart bootcode -p /boot/gptzfsboot -i $N ada0 2155 The value $N will typically be 1. For EFI booting, see EFI notes. 2156 2157 3) zpool upgrade the root pool. New bootblocks will work with old 2158 pools, but not vice versa, so they need to be updated before any 2159 zpool upgrade. 2160 2161 Non-boot pools do not need these updates. 2162 2163 EFI notes 2164 --------- 2165 2166 There are two locations the boot loader can be installed into. The 2167 current location (and the default) is \efi\freebsd\loader.efi and using 2168 efibootmgr(8) to configure it. The old location, that must be used on 2169 deficient systems that don't honor efibootmgr(8) protocols, is the 2170 fallback location of \EFI\BOOT\BOOTxxx.EFI. Generally, you will copy 2171 /boot/loader.efi to this location, but on systems installed a long time 2172 ago the ESP may be too small and /boot/boot1.efi may be needed unless 2173 the ESP has been expanded in the meantime. 2174 2175 Recent systems will have the ESP mounted on /boot/efi, but older ones 2176 may not have it mounted at all, or mounted in a different 2177 location. Older arm SD images with MBR used /boot/msdos as the 2178 mountpoint. The ESP is a MSDOS filesystem. 2179 2180 The EFI boot loader rarely needs to be updated. For ZFS booting, 2181 however, you must update loader.efi before you do 'zpool upgrade' the 2182 root zpool, otherwise the old loader.efi may reject the upgraded zpool 2183 since it does not automatically understand some new features. 2184 2185 See loader.efi(8) and uefi(8) for more details. 2186 2187 To build a kernel 2188 ----------------- 2189 If you are updating from a prior version of FreeBSD (even one just 2190 a few days old), you should follow this procedure. It is the most 2191 failsafe as it uses a /usr/obj tree with a fresh mini-buildworld, 2192 2193 make kernel-toolchain 2194 make -DALWAYS_CHECK_MAKE buildkernel KERNCONF=YOUR_KERNEL_HERE 2195 make -DALWAYS_CHECK_MAKE installkernel KERNCONF=YOUR_KERNEL_HERE 2196 2197 If you are running kernel modules from ports, see FOOTNOTE [1]. 2198 2199 To test a kernel once 2200 --------------------- 2201 If you just want to boot a kernel once (because you are not sure 2202 if it works, or if you want to boot a known bad kernel to provide 2203 debugging information) run 2204 make installkernel KERNCONF=YOUR_KERNEL_HERE KODIR=/boot/testkernel 2205 nextboot -k testkernel 2206 2207 To rebuild everything and install it on the current system. 2208 ----------------------------------------------------------- 2209 # Note: sometimes if you are running current you gotta do more than 2210 # is listed here if you are upgrading from a really old current. 2211 2212 <make sure you have good level 0 dumps> [2] 2213 make buildworld 2214 <make sure any needed PORTS_MODULES are set> [1] 2215 make buildkernel KERNCONF=YOUR_KERNEL_HERE 2216 make installkernel KERNCONF=YOUR_KERNEL_HERE 2217 <reboot in single user> [3] 2218 etcupdate -p [5] 2219 make installworld 2220 etcupdate -B [4] 2221 make delete-old [6] 2222 <reboot> 2223 2224 To cross-install current onto a separate partition 2225 -------------------------------------------------- 2226 # In this approach we use a separate partition to hold 2227 # current's root, 'usr', and 'var' directories. A partition 2228 # holding "/", "/usr" and "/var" should be about 2GB in 2229 # size. 2230 2231 <make sure you have good level 0 dumps> 2232 <boot into -stable> 2233 make buildworld 2234 make buildkernel KERNCONF=YOUR_KERNEL_HERE [1] 2235 <maybe newfs current's root partition> 2236 <mount current's root partition on directory ${CURRENT_ROOT}> 2237 make installworld DESTDIR=${CURRENT_ROOT} -DDB_FROM_SRC 2238 make distribution DESTDIR=${CURRENT_ROOT} # if newfs'd 2239 make installkernel KERNCONF=YOUR_KERNEL_HERE DESTDIR=${CURRENT_ROOT} 2240 cp /etc/fstab ${CURRENT_ROOT}/etc/fstab # if newfs'd 2241 <edit ${CURRENT_ROOT}/etc/fstab to mount "/" from the correct partition> 2242 <reboot into current> 2243 <do a "native" rebuild/install as described in the previous section> 2244 <maybe install compatibility libraries from ports/misc/compat*> 2245 <reboot> 2246 2247 2248 To upgrade in-place from stable to current 2249 ---------------------------------------------- 2250 <make sure you have good level 0 dumps> [2] 2251 make buildworld [9] 2252 <make sure any needed PORTS_MODULES are set> [1] 2253 make buildkernel KERNCONF=YOUR_KERNEL_HERE [8] 2254 make installkernel KERNCONF=YOUR_KERNEL_HERE 2255 <reboot in single user> [3] 2256 etcupdate -p [5] 2257 make installworld 2258 etcupdate -B [4] 2259 make delete-old [6] 2260 <reboot> 2261 2262 Make sure that you've read the UPDATING file to understand the 2263 tweaks to various things you need. At this point in the life 2264 cycle of current, things change often and you are on your own 2265 to cope. The defaults can also change, so please read ALL of 2266 the UPDATING entries. 2267 2268 Also, if you are tracking -current, you must be subscribed to 2269 freebsd-current@freebsd.org. Make sure that before you update 2270 your sources that you have read and understood all the recent 2271 messages there. If in doubt, please track -stable which has 2272 much fewer pitfalls. 2273 2274FOOTNOTES: 2275 2276 [1] If you have third party modules, such as drm-kmod or vmware, you 2277 should disable them at this point so they don't crash your system on 2278 reboot. Alternatively, you should rebuild all the modules you have in 2279 your system and install them as well. If you are running -current, you 2280 should seriously consider placing all sources to all the modules for 2281 your system (or symlinks to them) in /usr/local/sys/modules so this 2282 happens automatically. If all your modules come from ports, then adding 2283 the port origin directories to PORTS_MODULES instead is also automatic 2284 and effective, eg: 2285 PORTS_MODULES+=graphics/drm-kmod graphics/nvidia-drm-kmod 2286 2287 [2] To make complete dumps on zfs(4), use bectl(8), which 2288 creates bootable snapshots of configurable depth that are 2289 selectable via the bootloader. For ufs(4), use dump(8) and 2290 restore(8). 2291 2292 [3] From the bootblocks, boot -s, and then do 2293 fsck -p 2294 mount -u / 2295 mount -a 2296 sh /etc/rc.d/zfs start # mount zfs filesystem, if needed 2297 cd src # full path to source 2298 adjkerntz -i # if CMOS is wall time 2299 Also, when doing a major release upgrade, it is required that you boot 2300 into single user mode to do the installworld. 2301 2302 [4] Note: This step is non-optional. Failure to do this step 2303 can result in a significant reduction in the functionality of the 2304 system. Attempting to do it by hand is not recommended and those 2305 that pursue this avenue should read this file carefully, as well 2306 as the archives of freebsd-current and freebsd-hackers mailing lists 2307 for potential gotchas. See etcupdate(8) for more information. 2308 2309 [5] Usually this step is a no-op. However, from time to time 2310 you may need to do this if you get unknown user in the following 2311 step. 2312 2313 [6] This only deletes old files and directories. Old libraries 2314 can be deleted by "make delete-old-libs", but you have to make 2315 sure that no program is using those libraries anymore. 2316 2317 [8] The new kernel must be able to run existing binaries used by an 2318 installworld. When upgrading across major versions, the new kernel's 2319 configuration must include the correct COMPAT_FREEBSD<n> option for 2320 existing binaries (e.g. COMPAT_FREEBSD11 to run 11.x binaries). Failure 2321 to do so may leave you with a system that is hard to boot to recover. A 2322 GENERIC kernel will include suitable compatibility options to run 2323 binaries from older branches. Note that the ability to run binaries 2324 from unsupported branches is not guaranteed. 2325 2326 Make sure that you merge any new devices from GENERIC since the 2327 last time you updated your kernel config file. Options also 2328 change over time, so you may need to adjust your custom kernels 2329 for these as well. 2330 2331 [9] If CPUTYPE is defined in your /etc/make.conf, make sure to use the 2332 "?=" instead of the "=" assignment operator, so that buildworld can 2333 override the CPUTYPE if it needs to. 2334 2335 MAKEOBJDIRPREFIX must be defined in an environment variable, and 2336 not on the command line, or in /etc/make.conf. buildworld will 2337 warn if it is improperly defined. 2338FORMAT: 2339 2340This file contains a list, in reverse chronological order, of major 2341breakages in tracking -current. It is not guaranteed to be a complete 2342list of such breakages, and only contains entries since September 23, 2011. 2343If you need to see UPDATING entries from before that date, you will need 2344to fetch an UPDATING file from an older FreeBSD release. 2345 2346Copyright information: 2347 2348Copyright 1998-2009 M.
