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 3020250816: 31 Sendmail's libmilter has been moved to its own package. If you want 32 to compile applications that use libmilter, you should install the 33 FreeBSD-libmilter* packages. 34 35 If you only have FreeBSD-sendmail installed for applications that 36 require libmilter, you can now remove it. 37 3820250815: 39 jemalloc 5.3.0 has been committed to the tree. 40 4120250815: 42 The removal of Secure RPC DES authentication notced in 20250810 43 has been reverted. (However, it is still non-functional.) 44 4520250813: 46 Commit cce64f2e6851 changed the internal KAPI between the NFS 47 modules. As such, all of them need to be rebuilt from sources. 48 __FreeBSD_version has been bumped to 1500060 already today, 49 so I will not bump it again for this. 50 5120250813: 52 The gpiobus_attach_bus() function has been removed. Drivers should now 53 use the gpiobus_add_bus() function instead. The difference being that 54 gpiobus_add_bus() doesn't call bus_attach_children(), calling it will 55 be the responsibility of the caller now. 56 5720250810: 58 Support for Secure RPC DES authentication has been removed. 59 The keyserv(8) daemon was already removed, but support for it in libc 60 has also been removed, so if you somehow still had keyserv installed, 61 it will now stop working. There is no workaround for this. Removing 62 DES is considered a feature. 63 6420250808: 65 The CLEAN option has been switched back from default-off to 66 default-on. This reverts the 20240729 change below. 67 6820250807: 69 routed(8) and route6d(8) have moved to the FreeBSD-rip package. 70 If you use either of these, you should install the new package. 71 7220250806: 73 if_epair(4) now uses ether_gen_addr(9) to generate a stable MAC 74 address. 75 To keep using the random address, set the loader tunable 76 net.link.epair.ether_gen_addr=0. 77 7820250804: 79 bsdconfig (including sysrc(8)) has moved to the new bsdconfig 80 package. If you use pkgbase and wish to use bsdconfig, you should 81 install FreeBSD-bsdconfig. 82 8320250730: 84 The usbhid(4) USB HID driver is now enabled by default, and will be 85 used in preference to other USB HID drivers like ukbd(4), ums(4), and 86 uhid(4). Work on a FIDO/U2F driver and moused(8) is in progress. 87 The default is being switched now so that we can find and fix any 88 additional issues prior to FreeBSD 15.0. 89 90 To revert to the previous USB HID driver behavior, set the loader 91 tunable hw.usb.usbhid.enable=0. 92 9320250727: 94 bmake (i.e., /usr/bin/make and /usr/share/mk) has moved to a new 95 package, FreeBSD-bmake. If you use pkgbase and you need make, you 96 should install this package. 97 9820250726: 99 amd64 kernel configurations must contain "options SMP". 100 10120250725: 102 gssd(8) has been moved to a new package, FreeBSD-gssd. If you use 103 pkgbase and you need gssd, you should install this package. 104 10520250724: 106 The Kerberos packages which are built when WITH_MITKRB5 is enabled 107 have been renamed from FreeBSD-krb5* to FreeBSD-kerberos*. This 108 affects pkgbase users who manually enabled WITH_MITKRB5, *or* use 109 the default value of WITH_MITKRB5 and updated past c7da9fb90b0b 110 (20250721) which made WITH_MITKRB5 the default. 111 112 In either case, if you have FreeBSD-krb5* packages installed, you 113 should remove them and (re)install the equivalent FreeBSD-kerberos* 114 packages instead. 115 11620250721: 117 WITH_MITKRB5 is now enabled by default. MIT KRB5 has replaced 118 Heimdal in base. Ports that use USES=gssapi must be rebuilt. 119 A clean buildworld is required. 120 12120250719: 122 Commits 392a82b225 and c00baac0ab both changed the 123 internal API between the NFS modules. As such, all 124 these modules need to be rebuilt from sources. 125 __FreeBSD_version was bumped to 1500053 for this. 126 12720250710: 128 The shar(1) utility has been removed from base. The 129 sysutils/freebsd-shar port was created to maintain this version of 130 shar(1) past its removal from base. 131 13220250704: 133 LinuxKPI device.h and acpi changes effecting drivers and drm-kmod. 134 Bump __FreeBSD_version 1500050 to be able to detect these changes. 135 13620250630: 137 Commits 171f66b0c2ca and 8e2a90ac8089 changed the internal 138 api between nfscommon.ko and the other nfs modules. 139 Bump __FreeBSD_version to 1500049 for this. 140 All NFS related modules must be rebuilt from up-to-date 141 sources. 142 14320250625: 144 "make delete-old" will now remove the Forth bootloader entirely 145 if the system is built with WITHOUT_FORTH. 146 14720250614: 148 MIT KRB5 (MIT Kerberos5) has been imported into 15-CURRENT. To 149 and install MIT KRB5, add WITH_MITKRB5=yes to /etc/src.conf. This 150 will build and install MIT KRB5 1.21.3. And it will remove Heimdal 151 1.5.2 when delete-old and delete-old-libs are run. To revert back 152 simply buildworld/installworld again with delete-old-libs and 153 delete-old. 154 155 At the moment we only know of a couple of ports that might be 156 affected. Adjusting libmap.conf does not circumvent runtime issues. 157 The few affected ports must be rebuilt. A successful exp-run will be 158 run before MIT KRB5 becomes default. 159 160 Those using the KDC in FreeBSD base may wish to wait. The Heimdal 161 HDB is incompatible with the MIT KRB5 KDC. The migration procedure 162 is a little involved. 163 16420250603: 165 LinuxKPI dma-mapping.h were pulled into the tree from drm-kmod. 166 Bump _FreeBSD_version to 1500045 to be able to detect this change. 167 16820250527: 169 pf changed extension header handling. It now treats AH headers on IPv4 just 170 like AH headers on IPv6 and skips over them, allowing filtering on the inner 171 protocol. 172 17320250527: 174 pf now blocks IPv6 packets with a hop-by-hop or destination options header by 175 default. Such packets can be passed by adding "allow-opts" to the rule. IPv6 176 options are now handled just like their IPv4 counterparts. 177 17820250527: 179 The CAM target layer userland, i.e. ctld(8), ctladm(8) and ctlstat(8), 180 has moved to the new FreeBSD-ctl package. If you use pkgbase and you 181 need the CAM Target Layer, you should install the new package. 182 183 Development-related tools (e.g. ar and nm) have moved to the new 184 "FreeBSD-toolchain" package, which subsumes and obsoletes the 185 existing "FreeBSD-elftoolchain" package. If you use pkgbase and 186 need to compile software, you should install the new package and 187 ensure the old FreeBSD-elftoolchain* packages are completely removed. 188 18920250521: 190 Commit e64fe5ad3a23 removed in6_maxmtu and its setter in6_setmaxmtu(). 191 in6_maxmtu is used to store the max IPv6 MTU of all interfaces, 192 however it does not have any in-tree consumers since the introduction 193 from the KAME project. The removal should have little impact, and the 194 max IPv6 MTU can be easily retrieved by iterating over all the attached 195 interface if 3rd party modules need it. 196 19720250515: 198 Commit 772258c89f28 changed the internal API between the nfscommon 199 and nfscl modules. Both need to be built from updated sources. 200 20120250513: 202 The bridge(4) sysctl net.link.bridge.member_ifaddrs now defaults to 0, 203 meaning that interfaces added to a bridge may not have IP addresses 204 assigned. Refer to bridge(4) for more information. 205 20620250507: 207 UMASS quirks and auto-quirk probing has been overhauled. CAM now won't 208 send SYNCHRONIZE CACHE unless MODE PAGE 8 is present and valid. This 209 should allow more devices to work (since the auto quirk code was updated 210 in 14 and broke several e-readers and the like). Please send imp@freebsd.org 211 any regression reports. 212 21320250504: 214 Commit 9419e086e1a3 changed the internal API between the nfscommon 215 and nfscl modules. Both need to be built from updated sources. 216 21720250412: 218 LinuxKPI alloc routines were changed to return physically contiguous 219 memory where expected. These changes may require out-of-tree drivers 220 to be recompiled. 221 Bump __FreeBSD_version to 1500037 to be able to detect this change. 222 22320250409: 224 Intel iwlwifi firmware has been removed from the src repository. 225 Before updating their system, users of iwlwifi(4) or iwx(4) must 226 install the appropriate firmware for their chipset using fwget(8) or 227 building it from ports. 228 22920250314: 230 We now use LLVM's binary utilities (nm, objcopy, etc.) by default. 231 The WITHOUT_LLVM_BINUTILS src.conf(5) knob can be used to revert to 232 ELF Tool Chain tools if desired. 233 23420250303: 235 Commit 4a77657cbc01 changed the ABI between ipfw(8) and ipfw(4). 236 Please note that the old ipfw(8) binary will not work with the new 237 ipfw(4) module. Therefore, it is recommended to disable ipfw during 238 the upgrade, otherwise the host system may become inaccessible because 239 ipfw rules cannot be installed with the old binary. 240 24120250214: 242 Commit 4517fbfd4251 modified the internal API between the 243 nfscommon and nfscl modules. As such, both of these modules 244 need to be rebuilt from sources. 245 24620250201: 247 The NFS related daemons, that provide RPC services to the kernel: 248 gssd(8), rpcbind(8), rpc.tlsservd(8) and rpc.tlsclntd(8), now use a 249 different transport - netlink(4) socket instead of unix(4). Users of 250 NFS need to upgrade both kernel and world (binaries and libc) at once. 251 Also, any revision between 88cd1e17a7d8 and 99e5a70046da should be 252 avoided. 253 25420250129: 255 Defer the January 19, 2038 date limit in UFS1 filesystems to 256 February 7, 2106. This affects only UFS1 format filesystems. 257 See commit message 1111a44301da for details. 258 25920250127: 260 The Allwinner a10_timer driver has been renamed to aw_driver. If you 261 have a custom kernel configuration including the line 'device 262 a10_timer', it must be adjusted to 'device aw_timer'. The same applies 263 for device exclusions with 'nodevice'. 264 26520250106: 266 A new SOC_ROCKCHIP options appeared, so if you have a custom kernel configuration 267 targetting Rockchip SoC you need to add it so shared and mandatory drivers for 268 this SoC familly will be selected. 269 Also a new rk8xx device was added, this select the base driver for Rockchip PMIC. 270 27120241223: 272 The layout of NFS file handles for the tarfs, tmpfs, cd9660, and ext2fs 273 file systems has changed. An NFS server that exports any of these file 274 systems will need its clients to unmount and remount the exports. 275 27620241216: 277 The iwm(4) firmwares are no longer compiled as kernel modules but instead 278 shipped as raw files. For pkgbase users if you use iwm(4) you will need 279 to install the FreeBSD-firmware-iwm package. 280 28120241124: 282 The OpenBSD derived bc and dc implementations and the WITHOUT_GH_BC 283 option that allowed building them instead of the advanced version 284 imported more than 4 years ago have been removed. 285 28620241107: 287 The ng_ubt(4) driver now requires firmwares to be loaded on Realtek 288 adaptors with rtlbtfw(8) utility. It no longer attaches to devices 289 standing in bootloader mode. Firmware files are available in the 290 comms/rtlbt-firmware port. 291 29220241025: 293 The support for the rc_fast_and_loose variable has been removed from 294 rc.subr(8). Users setting rc_fast_and_loose on their systems are 295 advised to make sure their customizations to rc service scripts 296 do not depend on having a single shell environment shared across 297 all the rc service scripts during booting and shutdown. 298 29920241013: 300 The ciss driver was updated to cope better with hotplug events that 301 caused it to panic before, and to support more than 48 drives attached 302 to the card. These changes were made w/o benefit of hardware for testing 303 and ciss(4) users should be on the lookout for regressions. 304 30520240729: 306 The build now defaults to WITHOUT_CLEAN - i.e., no automatic clean 307 is performed at the beginning of buildworld or buildkernel. The 308 WITH_CLEAN src.conf(5) knob can be used to restore the previous 309 behaviour. 310 311 If you encounter incremental build issues, please report them to the 312 freebsd-current mailing list so that a special-case dependency can be 313 added, if necessary. 314 31520240715: 316 We now lean more heavily on ACPI enumeration for some traditional 317 devices. uart has moved from isa to acpi so the hints act as wiring 318 instead of device enumeration. Hints for parallel port, floppy, etc 319 have been removed. Before upgrading, grep your dmesg for lines like: 320 uart1: non-PNP ISA device will be removed from GENERIC in FreeBSD 15. 321 to see if you need to start including hints for the device on isa 322 in your loader.conf or device.hints file. APU1 (but not APU2) boards 323 are known to be affected, but there may be others. 324 32520240712: 326 Support for armv6 has been disconnected and is being removed. 327 32820240617: 329 ifconfig now treats IPv4 addresses without a width or mask as an error. 330 Specify the desired mask or width along with the IP address on the 331 ifconfig command line and in rc.conf. 332 33320240428: 334 OpenBSM auditing runtime (auditd, etc.) has been moved into the new 335 package FreeBSD-audit. If you use OpenBSM auditing and pkgbase, you 336 should install FreeBSD-audit. 337 33820240424: 339 cron, lpr, and ntpd have been moved from FreeBSD-utilities into their 340 own packages. If you use pkgbase, you should install the relevant 341 packages: FreeBSD-cron, FreeBSD-lp, or FreeBSD-ntp. 342 34320240406: 344 Clang, llvm, lld, lldb, compiler-rt, libc++, libunwind and openmp have 345 been upgraded to 18.1.6. It is important that you run `make delete-old` 346 as described in the COMMON ITEMS section, otherwise several libc++ 347 headers that are obsolete and need to be removed can cause compilation 348 errors in C++ programs. 349 35020240205: 351 For dynamically linked programs, system calls are now made from 352 libsys rather than libc. No change in linkage is required as 353 libsys is an auxiliary filter for libc. People building custom 354 images must ensure that libsys.so.7 is included. 355 35620240202: 357 Loader now also read configuration files listed in local_loader_conf_files. 358 Files listed here are the last ones read. And /boot/loader.conf.local was 359 moved from loader_conf_files to local_loader_conf_files leaving only 360 loader.conf and device.hints in loader_conf_files by default. 361 362 The following sequencing is applied: 363 364 1. Bootstrap: 365 /boot/defaults/loader.conf 366 367 2. Read loader_conf_files files: 368 /boot/device.hints 369 /boot/loader.conf 370 371 3. Read loader_conf_dirs files: 372 /boot/loader.conf.d/*.conf 373 374 4. And finally, rread local_loader_conf_files files: 375 /boot/loader.conf.local 376 37720240201: 378 sendmail 8.18.1 has been imported and merged. This version enforces 379 stricter RFC compliance by default, especially with respect to line 380 endings. This may cause issues with receiving messages from 381 non-compliant MTAs; please see the first 8.18.1 release note in 382 contrib/sendmail/RELEASE_NOTES for mitigations. 383 38420240111: 385 Commit cc760de2183f changed the internal interface between 386 the nfscommon and nfscl modules. As such, both need to be 387 rebuilt from sources. Therefore, __FreeBSD_version was 388 bumped to 1500010. 389 39020231120: 391 If you have an arm64 system that uses ACPI, you will need to update your 392 loader.efi in the ESP when you update past this point. Detection of ACPI 393 was moved earlier in the binary so the scripts could use it, but old 394 binaries don't have this, so we default to 'no ACPI' in this case. You can 395 undisable ACPI by doing 396 OK unset hint.acpi.0.disabled 397 This can also be used to recover any other system that was updated in the 398 small window where amd64 was also broken. 399 40020231113: 401 The WITHOUT_LLD_IS_LD option has been removed. When LLD is enabled 402 it is always installed as /usr/bin/ld. 403 40420231027: 405 Forward compatibility (running the new code on old kernels) for the 406 "ino64" project have been removed. The need for it has passed long ago. 407 40820231018: 409 Commit 57ce37f9dcd0 changed the internal KAPI between the 410 nfscommon and nfscl modules. Both must be rebuilt from sources. 411 41220231010: 413 dialog(1) has been replaced in base by bsddialog(1), while most of the 414 time replacing a dialog(1) call by a bsddialog(1) call works out of the 415 box, bsddialog(1) is not considered as a drop-in replacement for 416 dialog(1). 417 418 If you do depend on dialog(1) functionality, please install cdialog 419 from ports: 420 421 pkg install cdialog 422 42320230927: 424 The EARLY_AP_STARTUP kernel option is mandatory on x86. The option 425 has been added to DEFAULTS, so it should automatically be included in 426 custom kernel configurations without any additional change. 427 42820230922: 429 A new loader tunable net.pf.default_to_drop allows pf(4)’s default 430 behaviour to be changed from pass to drop. Previously this required 431 recompiling the kernel with the option PF_DEFAULT_TO_DROP. 432 43320230914: 434 Enable splitting out pkgbase manpages into separate packages by 435 default. To disable this, set WITHOUT_MANSPLITPKG=yes in src.conf. 436 43720230911: 438 Move standard include files to the clibs-dev package and move clang 439 internal libraries and headers to clang and clang-dev. Upgrading systems 440 installed using pkgbase past this change involves extra steps to allow 441 for these file moves: 442 443 pkg upgrade -y FreeBSD-utilities 444 pkg upgrade -y FreeBSD-utilities-dev 445 pkg upgrade -y 446 44720230909: 448 Enable vnet sysctl variables to be loader tunable. SYSCTLs which 449 belongs to VNETs can be initialized during early boot or module 450 loading if they are marked with CTLFLAG_TUN and there are 451 corresponding kernel environment variables. 452 45320230901: 454 The WITH_INIT_ALL_PATTERN and WITH_INIT_ALL_ZERO build options have 455 been replaced by INIT_ALL=pattern and INIT_ALL=zero respectively. 456 45720230824: 458 FreeBSD 15.0-CURRENT. 459 46020230817: 461 Serial communication (in boot loaders, kernel, and userland) has 462 been changed to default to 115200 bps, in line with common industry 463 practice and typcial firmware serial console redirection 464 configuration. 465 466 Note that the early x86 BIOS bootloader (i.e., boot0sio) does not 467 support rates above 9600 bps and is not changed. boot0sio users may 468 set BOOT_COMCONSOLE_SPEED=9600 to use 9600 for all of the boot 469 components, or use the standard boot0 and have the boot2 stage start 470 with the serial port at 115200. 471 47220230807: 473 Following the general removal of MIPS support, the ath(4) AHB bus- 474 frontend has been removed, too, and building of the PCI support is 475 integrated with the ath(4) main module again. As a result, there's 476 no longer a need for if_ath_pci_load="YES" in /boot/loader.conf or 477 "device ath_pci" in the kernel configuration. 478 47920230803: 480 MAXCPU has been increased to 1024 in the amd64 GENERIC kernel config. 481 Out-of-tree kernel modules will need to be rebuilt. 482 48320230724: 484 CAM has been mechanically updated s/u_int(64|32|16|8)_t/uint\1_t/g 485 to move to the standard uintXX_t types from the old, traditional 486 BSD u_intXX_t types. This should be a NOP, but may cause problems 487 for out of tree changes. The SIMs were not updated since most of 488 the old u_intXX_t uses weren't due to CAM interfaces. 489 49020230713: 491 stable/14 branch created. 492 49320230629: 494 The heuristic for detecting old chromebooks with an EC bug that requires 495 atkbdc driver workarounds has changed. There should be no functional 496 change, but if your old chromebook's keyboard stops working, please 497 file a PR and assign it to imp. 498 49920230623: 500 OpenSSL has been updated to version 3.0, including changes throughout 501 the base system. It is important to rebuild third-party software 502 after upgrading. 503 50420230619: 505 To enable pf rdr rules for connections initiated from the host, pf 506 filter rules can be optionally enabled for packets delivered 507 locally. This can change the behavior of rules which match packets 508 delivered to lo0. To enable this feature: 509 510 sysctl net.pf.filter_local=1 511 service pf restart 512 513 When enabled, its best to ensure that packets delivered locally are not 514 filtered, e.g. by adding a 'skip on lo' rule. 515 51620230613: 517 Improvements to libtacplus(8) mean that tacplus.conf(5) now 518 follows POSIX shell syntax rules. This may cause TACACS+ 519 authentication to fail if the shared secret contains a single 520 quote, double quote, or backslash character which isn't 521 already properly quoted or escaped. 522 52320230612: 524 Belatedly switch the default nvme block device on x86 from nvd to nda. 525 nda created nvd compatibility links by default, so this should be a 526 nop. If this causes problems for your application, set hw.nvme.use_nvd=1 527 in your loader.conf or add `options NVME_USE_NVD=1` to your kernel 528 config. To disable the nvd compatibility aliases, add 529 kern.cam.nda.nvd_compat=0 to loader.conf. The default has been nda on 530 all non-x86 platforms for some time now. If you need to fall back, 531 please email imp@freebsd.org about why. 532 533 Encrypted swap partitions need to be changed from nvd to nda if you 534 migrate, or you need to use the above to switch back to nvd. 535 53620230422: 537 Remove portsnap(8). Users are encouraged to obtain the ports tree 538 using git instead. 539 54020230420: 541 Add jobs.mk to save typing. Enables -j${JOB_MAX} and logging 542 eg. 543 make buildworld-jobs 544 runs 545 make -j${JOB_MAX} buildworld > ../buildworld.log 2>&1 546 547 where JOB_MAX is derrived from ncpus in local.sys.mk if not set in env. 548 54920230316: 550 Video related devices for some arm devices have been renamed. 551 If you have a custom kernel config and want to use hdmi output on 552 IMX6 board you need to add "device dwc_hdmi" "device imx6_hdmi" and 553 "device imx6_ipu" to it. 554 If you have a custom kernel config and want to use hdmi output on 555 TI AM335X board you need to add "device tda19988" to it. 556 If you add "device hdmi" in it you need to remove it as it doesn't 557 exist anymore. 558 55920230221: 560 Introduce new kernel options KBD_DELAY1 and KBD_DELAY2. See atkbdc(4) 561 for details. 562 56320230206: 564 sshd now defaults to having X11Forwarding disabled, following upstream. 565 Administrators who wish to enable X11Forwarding should add 566 `X11Forwarding yes` to /etc/ssh/sshd_config. 567 56820230204: 569 Since commit 75d41cb6967 Huawei 3G/4G LTE Mobile Devices do not default 570 to ECM, but NCM mode and need u3g and ucom modules loaded. See cdce(4). 571 57220230130: 573 As of commit 7c40e2d5f685, the dependency on netlink(4) has been added 574 to the linux_common(4) module. Users relying on linux_common may need 575 to complile netlink(4) module if it is not present in their kernel. 576 57720230126: 578 The WITHOUT_CXX option has been removed. C++ components in the base 579 system are now built unconditionally. 580 58120230113: 582 LinuxKPI pci.h changes may require out-of-tree drivers to be recompiled. 583 Bump _FreeBSD_version to 1400078 to be able to detect this change. 584 58520221212: 586 llvm-objump is now always installed as objdump. Previously there was 587 no /usr/bin/objdump unless the WITH_LLVM_BINUTILS knob was used. 588 589 Some LLVM objdump options have a different output format compared to 590 GNU objdump; readelf is available for inspecting ELF files, and GNU 591 objdump is available from the devel/binutils port or package. 592 59320221205: 594 dma(8) has replaced sendmail(8) as the default mta. For people willing 595 to reenable sendmail(8): 596 597 $ cp /usr/share/examples/sendmail/mailer.conf /etc/mail/mailer.conf 598 599 and add sendmail_enable="YES" to rc.conf. 600 60120221204: 602 hw.bus.disable_failed_devices has changed from 'false' to 'true' by 603 default. Now if newbus succeeds in probing a device, but fails to attach 604 the device, we'll disable the device. In the past, we'd keep retrying 605 the device on each new driver loaded. To get that behavior now, one 606 needs to use devctl to re-enable the device, and reprobe it (or set 607 the sysctl/tunable hw.bus.disable_failed_devices=false). 608 609 NOTE: This was reverted 20221205 due to unexpected compatibility issues 610 61120221122: 612 pf no longer accepts 'scrub fragment crop' or 'scrub fragment drop-ovl'. 613 These configurations are no longer automatically reinterpreted as 614 'scrub fragment reassemble'. 615 61620221121: 617 The WITHOUT_CLANG_IS_CC option has been removed. When Clang is enabled 618 it is always installed as /usr/bin/cc (and c++, cpp). 619 62020221026: 621 Some programs have been moved into separate packages. It is recommended 622 for pkgbase users to do: 623 624 pkg install FreeBSD-dhclient FreeBSD-geom FreeBSD-resolvconf \ 625 FreeBSD-devd FreeBSD-devmatch 626 627 after upgrading to restore all the component that were previously 628 installed. 629 63020221002: 631 OPIE has been removed from the base system. If needed, it can 632 be installed from ports (security/opie) or packages (opie). 633 Otherwise, make sure that your PAM policies do not reference 634 pam_opie or pam_opieaccess. 635 63620220610: 637 LinuxKPI pm.h changes require an update to the latest drm-kmod version 638 before re-compiling to avoid errors. 639 64020211230: 641 The macros provided for the manipulation of CPU sets (e.g. CPU_AND) 642 have been modified to take 2 source arguments instead of only 1. 643 Externally maintained sources that use these macros will have to 644 be adapted. The FreeBSD version has been bumped to 1400046 to 645 reflect this change. 646 64720211214: 648 A number of the kernel include files are able to be included by 649 themselves. A test has been added to buildworld to enforce this. 650 65120211209: 652 Remove mips as a recognized target. This starts the decommissioning of 653 mips support in FreeBSD. mips related items will be removed wholesale in 654 the coming days and weeks. 655 656 This broke the NO_CLEAN build for some people. Either do a clean build 657 or touch 658 lib/clang/include/llvm/Config/Targets.def 659 lib/clang/include/llvm/Config/AsmParsers.def 660 lib/clang/include/llvm/Config/Disassemblers.def 661 lib/clang/include/llvm/Config/AsmPrinters.def 662 before the build to force everything to rebuild that needs to. 663 66420211202: 665 Unbound support for RFC8375: The special-use domain 'home.arpa' is 666 by default blocked. To unblock it use a local-zone nodefault 667 statement in unbound.conf: 668 local-zone: "home.arpa." nodefault 669 670 Or use another type of local-zone to override with your choice. 671 672 The reason for this is discussed in Section 6.1 of RFC8375: 673 Because 'home.arpa.' is not globally scoped and cannot be secured 674 using DNSSEC based on the root domain's trust anchor, there is no way 675 to tell, using a standard DNS query, in which homenet scope an answer 676 belongs. Consequently, users may experience surprising results with 677 such names when roaming to different homenets. 678 67920211110: 680 Commit b8d60729deef changed the TCP congestion control framework so 681 that any of the included congestion control modules could be 682 the single module built into the kernel. Previously newreno 683 was automatically built in through direct reference. As of 684 this commit you are required to declare at least one congestion 685 control module (e.g. 'options CC_NEWRENO') and to also declare a 686 default using the CC_DEFAULT option (e.g. options CC_DEFAULT="newreno\"). 687 The GENERIC configuration includes CC_NEWRENO and defines newreno 688 as the default. If no congestion control option is built into the 689 kernel and you are including networking, the kernel compile will 690 fail. Also if no default is declared the kernel compile will fail. 691 69220211118: 693 Mips has been removed from universe builds. It will be removed from the 694 tree shortly. 695 69620211106: 697 Commit f0c9847a6c47 changed the arguments for VOP_ALLOCATE. 698 The NFS modules must be rebuilt from sources and any out 699 of tree file systems that implement their own VOP_ALLOCATE 700 may need to be modified. 701 70220211022: 703 The synchronous PPP kernel driver sppp(4) has been removed. 704 The cp(4) and ce(4) drivers are now always compiled with netgraph(4) 705 support, formerly enabled by NETGRAPH_CRONYX option. 706 70720211020: 708 sh(1) is now the default shell for the root user. To force root to use 709 the csh shell, please run the following command as root: 710 711 # chsh -s csh 712 71320211004: 714 Ncurses distribution has been split between libtinfow and libncurses 715 with libncurses.so becoming a linker (ld) script to seamlessly link 716 to libtinfow as needed. Bump _FreeBSD_version to 1400035 to reflect 717 this change. 718 71920210923: 720 As of commit 8160a0f62be6, the dummynet module no longer depends on the 721 ipfw module. Dummynet can now be used by pf as well as ipfw. As such 722 users who relied on this dependency may need to include ipfw in the 723 list of modules to load on their systems. 724 72520210922: 726 As of commit 903873ce1560, the mixer(8) utility has got a slightly 727 new syntax. Please refer to the mixer(8) manual page for more 728 information. The old mixer utility can be installed from ports: 729 audio/freebsd-13-mixer 730 73120210911: 732 As of commit 55089ef4f8bb, the global variable nfs_maxcopyrange has 733 been deleted from the nfscommon.ko. As such, nfsd.ko must be built 734 from up to date sources to avoid an undefined reference when 735 being loaded. 736 73720210817: 738 As of commit 62ca9fc1ad56 OpenSSL no longer enables kernel TLS 739 by default. Users can enable kernel TLS via the "KTLS" SSL 740 option. This can be enabled globally by using a custom 741 OpenSSL config file via OPENSSL_CONF or via an 742 application-specific configuration option for applications 743 which permit setting SSL options via SSL_CONF_cmd(3). 744 74520210811: 746 Commit 3ad1e1c1ce20 changed the internal KAPI between the NFS 747 modules. Therefore, all need to be rebuilt from sources. 748 74920210730: 750 Commit b69019c14cd8 removes pf's DIOCGETSTATESNV ioctl. 751 As of be70c7a50d32 it is no longer used by userspace, but it does mean 752 users may not be able to enumerate pf states if they update the kernel 753 past b69019c14cd8 without first updating userspace past be70c7a50d32. 754 75520210729: 756 As of commit 01ad0c007964 if_bridge member interfaces can no longer 757 change their MTU. Changing the MTU of the bridge itself will change the 758 MTU on all member interfaces instead. 759 76020210716: 761 Commit ee29e6f31111 changed the internal KAPI between the nfscommon 762 and nfsd modules. Therefore, both need to be rebuilt from sources. 763 Bump __FreeBSD_version to 1400026 for this KAPI change. 764 76520210715: 766 The 20210707 awk update brought in a change in behavior. This has 767 been corrected as of d4d252c49976. Between these dates, if you 768 installed a new awk binary, you may not be able to build a new 769 kernel because the change in behavior affected the genoffset 770 script used to build the kernel. If you did update, the fix is 771 to update your sources past the above hash and do 772 % cd usr.bin/awk 773 % make clean all 774 % sudo -E make install 775 to enable building kernels again. 776 77720210708: 778 Commit 1e0a518d6548 changed the internal KAPI between the NFS 779 modules. They all need to be rebuilt from sources. I did not 780 bump __FreeBSD_version, since it was bumped recently. 781 78220210707: 783 awk has been updated to the latest one-true-awk version 20210215. 784 This contains a number of minor bug fixes. 785 78620210624: 787 The NFSv4 client now uses the highest minor version of NFSv4 788 supported by the NFSv4 server by default instead of minor version 0, 789 for NFSv4 mounts. 790 The "minorversion" mount option may be used to override this default. 791 79220210618: 793 Bump __FreeBSD_version to 1400024 for LinuxKPI changes. 794 Most notably netdev.h can change now as the (last) dependencies 795 (mlx4/ofed) are now using struct ifnet directly, but also for PCI 796 additions and others. 797 79820210618: 799 The directory "blacklisted" under /usr/share/certs/ has been 800 renamed to "untrusted". 801 80220210611: 803 svnlite has been removed from base. Should you need svn for any reason 804 please install the svn package or port. 805 80620210611: 807 Commit e1a907a25cfa changed the internal KAPI between the krpc 808 and nfsserver. As such, both modules must be rebuilt from 809 sources. Bump __FreeBSD_version to 1400022. 810 81120210610: 812 The an(4) driver has been removed from FreeBSD. 813 81420210608: 815 The vendor/openzfs branch was renamed to vendor/openzfs/legacy to 816 start tracking OpenZFS upstream more closely. Please see 817https://lists.freebsd.org/archives/freebsd-current/2021-June/000153.html 818 for details on how to correct any errors that might result. The 819 short version is that you need to remove the old branch locally: 820 git update-ref -d refs/remotes/freebsd/vendor/openzfs 821 (assuming your upstream origin is named 'freebsd'). 822 82320210525: 824 Commits 17accc08ae15 and de102f870501 add new files to LinuxKPI 825 which break drm-kmod. In addition various other additions where 826 committed. Bump __FreeBSD_version to 1400015 to be able to 827 detect this. 828 82920210513: 830 Commit ca179c4d74f2 changed the package in which the OpenSSL 831 libraries and utilities are packaged. 832 It is recommended for pkgbase user to do: 833 pkg install -f FreeBSD-openssl 834 before pkg upgrade otherwise some dependencies might not be met 835 and pkg will stop working as libssl will not be present anymore 836 on the system. 837 83820210426: 839 Commit 875977314881 changed the internal KAPI between 840 the nfsd and nfscommon modules. As such these modules 841 need to be rebuilt from sources. 842 Without this patch in your NFSv4.1/4.2 server, enabling 843 delegations by setting vfs.nfsd.issue_delegations non-zero 844 is not recommended. 845 84620210411: 847 Commit 7763814fc9c2 changed the internal KAPI between 848 the krpc and NFS. As such, the krpc, nfscommon and 849 nfscl modules must all be rebuilt from sources. 850 Without this patch, NFSv4.1/4.2 mounts should not 851 be done with the nfscbd(8) daemon running, to avoid 852 needing a working back channel for server->client RPCs. 853 85420210330: 855 Commit 01ae8969a9ee fixed the NFSv4.1/4.2 server so that it 856 handles binding of the back channel as required by RFC5661. 857 Until this patch is in your server, avoid use of the "nconnects" 858 mount option for Linux NFSv4.1/4.2 mounts. 859 86020210225: 861 For 64-bit architectures the base system is now built with Position 862 Independent Executable (PIE) support enabled by default. It may be 863 disabled using the WITHOUT_PIE knob. A clean build is required. 864 86520210128: 866 Various LinuxKPI functionality was added which conflicts with DRM. 867 Please update your drm-kmod port to after the __FreeBSD_version 1400003 868 update. 869 87020210121: 871 stable/13 branch created. 872 87320210108: 874 PC Card attachments for all devices have been removed. In the case of 875 wi and cmx, the entire drivers were removed because they were only 876 PC Card devices. FreeBSD_version 1300134 should be used for this 877 since it was bumped so recently. 878 87920210107: 880 Transport-independent parts of HID support have been split off the USB 881 code in to separate subsystem. Kernel configs which include one of 882 ums, ukbd, uhid, atp, wsp, wmt, uaudio, ugold or ucycom drivers should 883 be updated with adding of "device hid" line. 884 88520210105: 886 ncurses installation has been modified to only keep the widechar 887 enabled version. Incremental build is broken for that change, so it 888 requires a clean build. 889 89020201223: 891 The FreeBSD project has migrated from Subversion to Git. Temporary 892 instructions can be found at 893 https://github.com/bsdimp/freebsd-git-docs/blob/main/src-cvt.md 894 and other documents in that repo. 895 89620201216: 897 The services database has been updated to cover more of the basic 898 services expected in a modern system. The database is big enough 899 that it will cause issues in mergemaster in Releases previous to 900 12.2 and 11.3, or in very old current systems from before r358154. 901 90220201215: 903 Obsolete in-tree GDB 6.1.1 has been removed. GDB (including kgdb) 904 may be installed from ports or packages. 905 90620201124: 907 ping6 has been merged into ping. It can now be called as "ping -6". 908 See ping(8) for details. 909 91020201108: 911 Default value of net.add_addr_allfibs has been changed to 0. 912 If you have multi-fib configuration and rely on existence of all 913 interface routes in every fib, you need to set the above sysctl to 1. 914 91520201030: 916 The internal pre-processor in the calendar(1) program has been 917 extended to support more C pre-processor commands (e.g. #ifdef, #else, 918 and #undef) and to detect unbalanced conditional statements. 919 Error messages have been extended to include the filename and line 920 number if processing stops to help fixing malformed data files. 921 92220201026: 923 All the data files for the calendar(1) program, except calendar.freebsd, 924 have been moved to the deskutils/calendar-data port, much like the 925 jewish calendar entries were moved to deskutils/hebcal years ago. After 926 make delete-old-files, you need to install it to retain full 927 functionality. calendar(1) will issue a reminder for files it can't 928 find. 929 93020200923: 931 LINT files are no longer generated. We now include the relevant NOTES 932 files. Note: This may cause conflicts with updating in some cases. 933 find sys -name LINT\* -delete 934 is suggested across this commit to remove the generated LINT files. 935 936 If you have tried to update with generated files there, the svn 937 command you want to un-auger the tree is 938 cd sys/amd64/conf 939 svn revert -R . 940 and then do the above find from the top level. Substitute 'amd64' 941 above with where the error message indicates a conflict. 942 94320200824: 944 OpenZFS support has been integrated. Do not upgrade root pools until 945 the loader is updated to support zstd. Furthermore, we caution against 946 'zpool upgrade' for the next few weeks. The change should be transparent 947 unless you want to use new features. 948 949 Not all "NO_CLEAN" build scenarios work across these changes. Many 950 scenarios have been tested and fixed, but rebuilding kernels without 951 rebuilding world may fail. 952 953 The ZFS cache file has moved from /boot to /etc to match the OpenZFS 954 upstream default. A fallback to /boot has been added for mountroot. 955 956 Pool auto import behavior at boot has been moved from the kernel module 957 to an explicit "zpool import -a" in one of the rc scripts enabled by 958 zfs_enable=YES. This means your non-root zpools won't auto import until 959 you upgrade your /etc/rc.d files. 960 96120200824: 962 The resume code now notifies devd with the 'kernel' system 963 rather than the old 'kern' subsystem to be consistent with 964 other use. The old notification will be created as well, but 965 will be removed prior to FreeBSD 14.0. 966 96720200821: 968 r362275 changed the internal API between the kernel RPC and the 969 NFS modules. As such, all the modules must be recompiled from 970 sources. 971 97220200817: 973 r364330 modified the internal API used between the NFS modules. 974 As such, all the NFS modules must be re-compiled from sources. 975 97620200816: 977 Clang, llvm, lld, lldb, compiler-rt, libc++, libunwind and openmp have 978 been upgraded to 11.0.0. Please see the 20141231 entry below for 979 information about prerequisites and upgrading, if you are not already 980 using clang 3.5.0 or higher. 981 98220200810: 983 r364092 modified the internal ABI used between the kernel NFS 984 modules. As such, all of these modules need to be rebuilt 985 from sources, so a version bump was done. 986 98720200807: 988 Makefile.inc has been updated to work around the issue documented in 989 20200729. It was a case where the optimization of using symbolic links 990 to point to binaries created a situation where we'd run new binaries 991 with old libraries starting midway through the installworld process. 992 99320200729: 994 r363679 has redefined some undefined behavior in regcomp(3); notably, 995 extraneous escapes of most ordinary characters will no longer be 996 accepted. An exp-run has identified all of the problems with this in 997 ports, but other non-ports software may need extra escapes removed to 998 continue to function. 999 1000 Because of this change, installworld may encounter the following error 1001 from rtld: Undefined symbol "regcomp@FBSD_1.6" -- It is imperative that 1002 you do not halt installworld. Instead, let it run to completion (whether 1003 successful or not) and run installworld once more. 1004 100520200627: 1006 A new implementation of bc and dc has been imported in r362681. This 1007 implementation corrects non-conformant behavior of the previous bc 1008 and adds GNU bc compatible options. It offers a number of extensions, 1009 is much faster on large values, and has support for message catalogs 1010 (a number of languages are already supported, contributions of further 1011 languages welcome). The option WITHOUT_GH_BC can be used to build the 1012 world with the previous versions of bc and dc. 1013 101420200625: 1015 r362639 changed the internal API used between the NFS kernel modules. 1016 As such, they all need to be rebuilt from sources. 1017 101820200613: 1019 r362158 changed the arguments for VFS_CHECKEXP(). As such, any 1020 out of tree file systems need to be modified and rebuilt. 1021 Also, any file systems that are modules must be rebuilt. 1022 102320200604: 1024 read(2) of a directory fd is now rejected by default. root may 1025 re-enable it for system root only on non-ZFS filesystems with the 1026 security.bsd.allow_read_dir sysctl(8) MIB if 1027 security.bsd.suser_enabled=1. 1028 1029 It may be advised to setup aliases for grep to default to `-d skip` if 1030 commonly non-recursively grepping a list that includes directories and 1031 the potential for the resulting stderr output is not tolerable. Example 1032 aliases are now installed, commented out, in /root/.cshrc and 1033 /root/.shrc. 1034 103520200523: 1036 Clang, llvm, lld, lldb, compiler-rt, libc++, libunwind and openmp have 1037 been upgraded to 10.0.1. Please see the 20141231 entry below for 1038 information about prerequisites and upgrading, if you are not already 1039 using clang 3.5.0 or higher. 1040 104120200512: 1042 Support for obsolete compilers has been removed from the build system. 1043 Clang 6 and GCC 6.4 are the minimum supported versions. 1044 104520200424: 1046 closefrom(2) has been moved under COMPAT12, and replaced in libc with a 1047 stub that calls close_range(2). If using a custom kernel configuration, 1048 you may want to ensure that the COMPAT_FREEBSD12 option is included, as 1049 a slightly older -CURRENT userland and older FreeBSD userlands may not 1050 be functional without closefrom(2). 1051 105220200414: 1053 Upstream DTS from Linux 5.6 was merged and they now have the SID 1054 and THS (Secure ID controller and THermal Sensor) node present. 1055 The DTB overlays have now been removed from the tree for the H3/H5 and 1056 A64 SoCs and the aw_sid and aw_thermal driver have been updated to 1057 deal with upstream DTS. If you are using those overlays you need to 1058 remove them from loader.conf and update the DTBs on the FAT partition. 1059 106020200310: 1061 Clang, llvm, lld, lldb, compiler-rt, libc++, libunwind and openmp have 1062 been upgraded to 10.0.0. Please see the 20141231 entry below for 1063 information about prerequisites and upgrading, if you are not already 1064 using clang 3.5.0 or higher. 1065 106620200309: 1067 The amd(8) automount daemon has been removed from the source tree. 1068 As of FreeBSD 10.1 autofs(5) is the preferred tool for automounting. 1069 amd is still available in the sysutils/am-utils port. 1070 107120200301: 1072 Removed brooktree driver (bktr.4) from the tree. 1073 107420200229: 1075 The WITH_GPL_DTC option has been removed. The BSD-licenced device tree 1076 compiler in usr.bin/dtc is used on all architectures which use dtc, and 1077 the GPL dtc is available (if needed) from the sysutils/dtc port. 1078 107920200229: 1080 The WITHOUT_LLVM_LIBUNWIND option has been removed. LLVM's libunwind 1081 is used by all supported CPU architectures. 1082 108320200229: 1084 GCC 4.2.1 has been removed from the tree. The WITH_GCC, 1085 WITH_GCC_BOOTSTRAP, and WITH_GNUCXX options are no longer available. 1086 Users who wish to build FreeBSD with GCC must use the external toolchain 1087 ports or packages. 1088 108920200220: 1090 ncurses has been updated to a newer version (6.2-20200215). Given the ABI 1091 has changed, users will have to rebuild all the ports that are linked to 1092 ncurses. 1093 109420200217: 1095 The size of struct vnet and the magic cookie have changed. 1096 Users need to recompile libkvm and all modules using VIMAGE 1097 together with their new kernel. 1098 109920200212: 1100 Defining the long deprecated NO_CTF, NO_DEBUG_FILES, NO_INSTALLLIB, 1101 NO_MAN, NO_PROFILE, and NO_WARNS variables is now an error. Update 1102 your Makefiles and scripts to define MK_<var>=no instead as required. 1103 1104 One exception to this is that program or library Makefiles should 1105 define MAN to empty rather than setting MK_MAN=no. 1106 110720200108: 1108 Clang/LLVM is now the default compiler and LLD the default 1109 linker for riscv64. 1110 111120200107: 1112 make universe no longer uses GCC 4.2.1 on any architectures. 1113 Architectures not supported by in-tree Clang/LLVM require an 1114 external toolchain package. 1115 111620200104: 1117 GCC 4.2.1 is now not built by default, as part of the GCC 4.2.1 1118 retirement plan. Specifically, the GCC, GCC_BOOTSTRAP, and GNUCXX 1119 options default to off for all supported CPU architectures. As a 1120 short-term transition aid they may be enabled via WITH_* options. 1121 GCC 4.2.1 is expected to be removed from the tree on 2020-03-31. 1122 112320200102: 1124 Support for armv5 has been disconnected and is being removed. The 1125 machine combination MACHINE=arm MACHINE_ARCH=arm is no longer valid. 1126 You must now use a MACHINE_ARCH of armv6 or armv7. The default 1127 MACHINE_ARCH for MACHINE=arm is now armv7. 1128 112920191226: 1130 Clang/LLVM is now the default compiler for all powerpc architectures. 1131 LLD is now the default linker for powerpc64. The change for powerpc64 1132 also includes a change to the ELFv2 ABI, incompatible with the existing 1133 ABI. 1134 113520191226: 1136 Kernel-loadable random(4) modules are no longer unloadable. 1137 113820191222: 1139 Clang, llvm, lld, lldb, compiler-rt, libc++, libunwind and openmp have 1140 been upgraded to 9.0.1. Please see the 20141231 entry below for 1141 information about prerequisites and upgrading, if you are not already 1142 using clang 3.5.0 or higher. 1143 114420191212: 1145 r355677 has modified the internal interface used between the 1146 NFS modules in the kernel. As such, they must all be upgraded 1147 simultaneously. I will do a version bump for this. 1148 114920191205: 1150 The root certificates of the Mozilla CA Certificate Store have been 1151 imported into the base system and can be managed with the certctl(8) 1152 utility. If you have installed the security/ca_root_nss port or package 1153 with the ETCSYMLINK option (the default), be advised that there may be 1154 differences between those included in the port and those included in 1155 base due to differences in nss branch used as well as general update 1156 frequency. Note also that certctl(8) cannot manage certs in the 1157 format used by the security/ca_root_nss port. 1158 115920191120: 1160 The amd(8) automount daemon has been disabled by default, and will be 1161 removed in the future. As of FreeBSD 10.1 the autofs(5) is available 1162 for automounting. 1163 116420191107: 1165 The nctgpio and wbwd drivers have been moved to the superio bus. 1166 If you have one of these drivers in a kernel configuration, then 1167 you should add device superio to it. If you use one of these drivers 1168 as a module and you compile a custom set of modules, then you should 1169 add superio to the set. 1170 117120191021: 1172 KPIs for network drivers to access interface addresses have changed. 1173 Users need to recompile NIC driver modules together with kernel. 1174 117520191021: 1176 The net.link.tap.user_open sysctl no longer prevents user opening of 1177 already created /dev/tapNN devices. Access is still controlled by 1178 node permissions, just like tun devices. The net.link.tap.user_open 1179 sysctl is now used only to allow users to perform devfs cloning of 1180 tap devices, and the subsequent open may not succeed if the user is not 1181 in the appropriate group. This sysctl may be deprecated/removed 1182 completely in the future. 1183 118420191009: 1185 mips, powerpc, and sparc64 are no longer built as part of 1186 universe / tinderbox unless MAKE_OBSOLETE_GCC is defined. If 1187 not defined, mips, powerpc, and sparc64 builds will look for 1188 the xtoolchain binaries and if installed use them for universe 1189 builds. As llvm 9.0 becomes vetted for these architectures, they 1190 will be removed from the list. 1191 119220191009: 1193 Clang, llvm, lld, lldb, compiler-rt, libc++, libunwind and openmp have 1194 been upgraded to 9.0.0. Please see the 20141231 entry below for 1195 information about prerequisites and upgrading, if you are not already 1196 using clang 3.5.0 or higher. 1197 119820191003: 1199 The hpt27xx, hptmv, hptnr, and hptrr drivers have been removed from 1200 GENERIC. They are available as modules and can be loaded by adding 1201 to /boot/loader.conf hpt27xx_load="YES", hptmv_load="YES", 1202 hptnr_load="YES", or hptrr_load="YES", respectively. 1203 120420190913: 1205 ntpd no longer by default locks its pages in memory, allowing them 1206 to be paged out by the kernel. Use rlimit memlock to restore 1207 historic BSD behaviour. For example, add "rlimit memlock 32" 1208 to ntp.conf to lock up to 32 MB of ntpd address space in memory. 1209 121020190823: 1211 Several of ping6's options have been renamed for better consistency 1212 with ping. If you use any of -ARWXaghmrtwx, you must update your 1213 scripts. See ping6(8) for details. 1214 121520190727: 1216 The vfs.fusefs.sync_unmount and vfs.fusefs.init_backgrounded sysctls 1217 and the "-o sync_unmount" and "-o init_backgrounded" mount options have 1218 been removed from mount_fusefs(8). You can safely remove them from 1219 your scripts, because they had no effect. 1220 1221 The vfs.fusefs.fix_broken_io, vfs.fusefs.sync_resize, 1222 vfs.fusefs.refresh_size, vfs.fusefs.mmap_enable, 1223 vfs.fusefs.reclaim_revoked, and vfs.fusefs.data_cache_invalidate 1224 sysctls have been removed. If you felt the need to set any of them to 1225 a non-default value, please tell asomers@FreeBSD.org why. 1226 122720190713: 1228 Default permissions on the /var/account/acct file (and copies of it 1229 rotated by periodic daily scripts) are changed from 0644 to 0640 1230 because the file contains sensitive information that should not be 1231 world-readable. If the /var/account directory must be created by 1232 rc.d/accounting, the mode used is now 0750. Admins who use the 1233 accounting feature are encouraged to change the mode of an existing 1234 /var/account directory to 0750 or 0700. 1235 123620190620: 1237 Entropy collection and the /dev/random device are no longer optional 1238 components. The "device random" option has been removed. 1239 Implementations of distilling algorithms can still be made loadable 1240 with "options RANDOM_LOADABLE" (e.g., random_fortuna.ko). 1241 124220190612: 1243 Clang, llvm, lld, lldb, compiler-rt, libc++, libunwind and openmp have 1244 been upgraded to 8.0.1. Please see the 20141231 entry below for 1245 information about prerequisites and upgrading, if you are not already 1246 using clang 3.5.0 or higher. 1247 124820190608: 1249 A fix was applied to i386 kernel modules to avoid panics with 1250 dpcpu or vnet. Users need to recompile i386 kernel modules 1251 having pcpu or vnet sections or they will refuse to load. 1252 125320190513: 1254 User-wired pages now have their own counter, 1255 vm.stats.vm.v_user_wire_count. The vm.max_wired sysctl was renamed 1256 to vm.max_user_wired and changed from an unsigned int to an unsigned 1257 long. bhyve VMs wired with the -S are now subject to the user 1258 wiring limit; the vm.max_user_wired sysctl may need to be tuned to 1259 avoid running into the limit. 1260 126120190507: 1262 The IPSEC option has been removed from GENERIC. Users requiring 1263 ipsec(4) must now load the ipsec(4) kernel module. 1264 126520190507: 1266 The tap(4) driver has been folded into tun(4), and the module has been 1267 renamed to tuntap. You should update any kld_list="if_tap" or 1268 kld_list="if_tun" entries in /etc/rc.conf, if_tap_load="YES" or 1269 if_tun_load="YES" entries in /boot/loader.conf to load the if_tuntap 1270 module instead, and "device tap" or "device tun" entries in kernel 1271 config files to select the tuntap device instead. 1272 127320190418: 1274 The following knobs have been added related to tradeoffs between 1275 safe use of the random device and availability in the absence of 1276 entropy: 1277 1278 kern.random.initial_seeding.bypass_before_seeding: tunable; set 1279 non-zero to bypass the random device prior to seeding, or zero to 1280 block random requests until the random device is initially seeded. 1281 For now, set to 1 (unsafe) by default to restore pre-r346250 boot 1282 availability properties. 1283 1284 kern.random.initial_seeding.read_random_bypassed_before_seeding: 1285 read-only diagnostic sysctl that is set when bypass is enabled and 1286 read_random(9) is bypassed, to enable programmatic handling of this 1287 initial condition, if desired. 1288 1289 kern.random.initial_seeding.arc4random_bypassed_before_seeding: 1290 Similar to the above, but for arc4random(9) initial seeding. 1291 1292 kern.random.initial_seeding.disable_bypass_warnings: tunable; set 1293 non-zero to disable warnings in dmesg when the same conditions are 1294 met as for the diagnostic sysctls above. Defaults to zero, i.e., 1295 produce warnings in dmesg when the conditions are met. 1296 129720190416: 1298 The loadable random module KPI has changed; the random_infra_init() 1299 routine now requires a 3rd function pointer for a bool (*)(void) 1300 method that returns true if the random device is seeded (and 1301 therefore unblocked). 1302 130320190404: 1304 r345895 reverts r320698. This implies that an nfsuserd(8) daemon 1305 built from head sources between r320757 (July 6, 2017) and 1306 r338192 (Aug. 22, 2018) will not work unless the "-use-udpsock" 1307 is added to the command line. 1308 nfsuserd daemons built from head sources that are post-r338192 are 1309 not affected and should continue to work. 1310 131120190320: 1312 The fuse(4) module has been renamed to fusefs(4) for consistency with 1313 other filesystems. You should update any kld_load="fuse" entries in 1314 /etc/rc.conf, fuse_load="YES" entries in /boot/loader.conf, and 1315 "options FUSE" entries in kernel config files. 1316 131720190304: 1318 Clang, llvm, lld, lldb, compiler-rt and libc++ have been upgraded to 1319 8.0.0. Please see the 20141231 entry below for information about 1320 prerequisites and upgrading, if you are not already using clang 3.5.0 1321 or higher. 1322 132320190226: 1324 geom_uzip(4) depends on the new module xz. If geom_uzip is statically 1325 compiled into your custom kernel, add 'device xz' statement to the 1326 kernel config. 1327 132820190219: 1329 drm and drm2 have been removed from the tree. Please see 1330 https://wiki.freebsd.org/Graphics for the latest information on 1331 migrating to the drm ports. 1332 133320190131: 1334 Iflib is no longer unconditionally compiled into the kernel. Drivers 1335 using iflib and statically compiled into the kernel, now require 1336 the 'device iflib' config option. For the same drivers loaded as 1337 modules on kernels not having 'device iflib', the iflib.ko module 1338 is loaded automatically. 1339 134020190125: 1341 The IEEE80211_AMPDU_AGE and AH_SUPPORT_AR5416 kernel configuration 1342 options no longer exist since r343219 and r343427 respectively; 1343 nothing uses them, so they should be just removed from custom 1344 kernel config files. 1345 134620181230: 1347 r342635 changes the way efibootmgr(8) works by requiring users to add 1348 the -b (bootnum) parameter for commands where the bootnum was previously 1349 specified with each option. For example 'efibootmgr -B 0001' is now 1350 'efibootmgr -B -b 0001'. 1351 135220181220: 1353 r342286 modifies the NFSv4 server so that it obeys vfs.nfsd.nfs_privport 1354 in the same as it is applied to NFSv2 and 3. This implies that NFSv4 1355 servers that have vfs.nfsd.nfs_privport set will only allow mounts 1356 from clients using a reserved port. Since both the FreeBSD and Linux 1357 NFSv4 clients use reserved ports by default, this should not affect 1358 most NFSv4 mounts. 1359 136020181219: 1361 The XLP config has been removed. We can't support 64-bit atomics in this 1362 kernel because it is running in 32-bit mode. XLP users must transition 1363 to running a 64-bit kernel (XLP64 or XLPN32). 1364 1365 The mips GXEMUL support has been removed from FreeBSD. MALTA* + qemu is 1366 the preferred emulator today and we don't need two different ones. 1367 1368 The old sibyte / swarm / Broadcom BCM1250 support has been 1369 removed from the mips port. 1370 137120181211: 1372 Clang, llvm, lld, lldb, compiler-rt and libc++ have been upgraded to 1373 7.0.1. Please see the 20141231 entry below for information about 1374 prerequisites and upgrading, if you are not already using clang 3.5.0 1375 or higher. 1376 137720181211: 1378 Remove the timed and netdate programs from the base tree. Setting 1379 the time with these daemons has been obsolete for over a decade. 1380 138120181126: 1382 On amd64, arm64 and armv7 (architectures that install LLVM's ld.lld 1383 linker as /usr/bin/ld) GNU ld is no longer installed as ld.bfd, as 1384 it produces broken binaries when ifuncs are in use. Users needing 1385 GNU ld should install the binutils port or package. 1386 138720181123: 1388 The BSD crtbegin and crtend code has been enabled by default. It has 1389 had extensive testing on amd64, arm64, and i386. It can be disabled 1390 by building a world with -DWITHOUT_BSD_CRTBEGIN. 1391 139220181115: 1393 The set of CTM commands (ctm, ctm_smail, ctm_rmail, ctm_dequeue) 1394 has been converted to a port (misc/ctm) and will be removed from 1395 FreeBSD-13. It is available as a package (ctm) for all supported 1396 FreeBSD versions. 1397 139820181110: 1399 The default newsyslog.conf(5) file has been changed to only include 1400 files in /etc/newsyslog.conf.d/ and /usr/local/etc/newsyslog.conf.d/ if 1401 the filenames end in '.conf' and do not begin with a '.'. 1402 1403 You should check the configuration files in these two directories match 1404 this naming convention. You can verify which configuration files are 1405 being included using the command: 1406 $ newsyslog -Nrv 1407 140820181019: 1409 Stable/12 was branched created. 1410 141120181015: 1412 Ports for the DRM modules have been simplified. Now, amd64 users should 1413 just install the drm-kmod port. All others should install 1414 drm-legacy-kmod. 1415 1416 Graphics hardware that's newer than about 2010 usually works with 1417 drm-kmod. For hardware older than 2013, however, some users will need 1418 to use drm-legacy-kmod if drm-kmod doesn't work for them. Hardware older 1419 than 2008 usually only works in drm-legacy-kmod. The graphics team can 1420 only commit to hardware made since 2013 due to the complexity of the 1421 market and difficulty to test all the older cards effectively. If you 1422 have hardware supported by drm-kmod, you are strongly encouraged to use 1423 that as you will get better support. 1424 1425 Other than KPI chasing, drm-legacy-kmod will not be updated. As outlined 1426 elsewhere, the drm and drm2 modules will be eliminated from the src base 1427 soon (with a limited exception for arm). Please update to the package 1428 asap and report any issues to x11@freebsd.org. 1429 1430 Generally, anybody using the drm*-kmod packages should add 1431 WITHOUT_DRM_MODULE=t and WITHOUT_DRM2_MODULE=t to avoid nasty 1432 cross-threading surprises, especially with automatic driver 1433 loading from X11 startup. These will become the defaults in 13-current 1434 shortly. 1435 143620181012: 1437 The ixlv(4) driver has been renamed to iavf(4). As a consequence, 1438 custom kernel and module loading configuration files must be updated 1439 accordingly. Moreover, interfaces previous presented as ixlvN to the 1440 system are now exposed as iavfN and network configuration files must 1441 be adjusted as necessary. 1442 144320181009: 1444 OpenSSL has been updated to version 1.1.1. This update included 1445 additional various API changes throughout the base system. It is 1446 important to rebuild third-party software after upgrading. The value 1447 of __FreeBSD_version has been bumped accordingly. 1448 144920181006: 1450 The legacy DRM modules and drivers have now been added to the loader's 1451 module blacklist, in favor of loading them with kld_list in rc.conf(5). 1452 The module blacklist may be overridden with the loader.conf(5) 1453 'module_blacklist' variable, but loading them via rc.conf(5) is strongly 1454 encouraged. 1455 145620181002: 1457 The cam(4) based nda(4) driver will be used over nvd(4) by default on 1458 powerpc64. You may set 'options NVME_USE_NVD=1' in your kernel conf or 1459 loader tunable 'hw.nvme.use_nvd=1' if you wish to use the existing 1460 driver. Make sure to edit /boot/etc/kboot.conf and fstab to use the 1461 nda device name. 1462 146320180913: 1464 Reproducible build mode is now on by default, in preparation for 1465 FreeBSD 12.0. This eliminates build metadata such as the user, 1466 host, and time from the kernel (and uname), unless the working tree 1467 corresponds to a modified checkout from a version control system. 1468 The previous behavior can be obtained by setting the /etc/src.conf 1469 knob WITHOUT_REPRODUCIBLE_BUILD. 1470 147120180826: 1472 The Yarrow CSPRNG has been removed from the kernel as it has not been 1473 supported by its designers since at least 2003. Fortuna has been the 1474 default since FreeBSD-11. 1475 147620180822: 1477 devctl freeze/thaw have gone into the tree, the rc scripts have been 1478 updated to use them and devmatch has been changed. You should update 1479 kernel, userland and rc scripts all at the same time. 1480 148120180818: 1482 The default interpreter has been switched from 4th to Lua. 1483 LOADER_DEFAULT_INTERP, documented in build(7), will override the default 1484 interpreter. If you have custom FORTH code you will need to set 1485 LOADER_DEFAULT_INTERP=4th (valid values are 4th, lua or simp) in 1486 src.conf for the build. This will create default hard links between 1487 loader and loader_4th instead of loader and loader_lua, the new default. 1488 If you are using UEFI it will create the proper hard link to loader.efi. 1489 1490 bhyve uses userboot.so. It remains 4th-only until some issues are solved 1491 regarding coexisting with multiple versions of FreeBSD are resolved. 1492 149320180815: 1494 ls(1) now respects the COLORTERM environment variable used in other 1495 systems and software to indicate that a colored terminal is both 1496 supported and desired. If ls(1) is suddenly emitting colors, they may 1497 be disabled again by either removing the unwanted COLORTERM from your 1498 environment, or using `ls --color=never`. The ls(1) specific CLICOLOR 1499 may not be observed in a future release. 1500 150120180808: 1502 The default pager for most commands has been changed to "less". To 1503 restore the old behavior, set PAGER="more" and MANPAGER="more -s" in 1504 your environment. 1505 150620180731: 1507 The jedec_ts(4) driver has been removed. A superset of its functionality 1508 is available in the jedec_dimm(4) driver, and the manpage for that 1509 driver includes migration instructions. If you have "device jedec_ts" 1510 in your kernel configuration file, it must be removed. 1511 151220180730: 1513 amd64/GENERIC now has EFI runtime services, EFIRT, enabled by default. 1514 This should have no effect if the kernel is booted via BIOS/legacy boot. 1515 EFIRT may be disabled via a loader tunable, efi.rt.disabled, if a system 1516 has a buggy firmware that prevents a successful boot due to use of 1517 runtime services. 1518 151920180727: 1520 Atmel AT91RM9200 and AT91SAM9, Cavium CNS 11xx and XScale 1521 support has been removed from the tree. These ports were 1522 obsolete and/or known to be broken for many years. 1523 152420180723: 1525 loader.efi has been augmented to participate more fully in the 1526 UEFI boot manager protocol. loader.efi will now look at the 1527 BootXXXX environment variable to determine if a specific kernel 1528 or root partition was specified. XXXX is derived from BootCurrent. 1529 efibootmgr(8) manages these standard UEFI variables. 1530 153120180720: 1532 zfsloader's functionality has now been folded into loader. 1533 zfsloader is no longer necessary once you've updated your 1534 boot blocks. For a transition period, we will install a 1535 hardlink for zfsloader to loader to allow a smooth transition 1536 until the boot blocks can be updated (hard link because old 1537 zfs boot blocks don't understand symlinks). 1538 153920180719: 1540 ARM64 now have efifb support, if you want to have serial console 1541 on your arm64 board when an screen is connected and the bootloader 1542 setup a frame buffer for us to use, just add : 1543 boot_serial=YES 1544 boot_multicons=YES 1545 in /boot/loader.conf 1546 For Raspberry Pi 3 (RPI) users, this is needed even if you don't have 1547 an screen connected as the firmware will setup a frame buffer are that 1548 u-boot will expose as an EFI frame buffer. 1549 155020180719: 1551 New uid:gid added, ntpd:ntpd (123:123). Be sure to run mergemaster 1552 or take steps to update /etc/passwd before doing installworld on 1553 existing systems. Do not skip the "mergemaster -Fp" step before 1554 installworld, as described in the update procedures near the bottom 1555 of this document. Also, rc.d/ntpd now starts ntpd(8) as user ntpd 1556 if the new mac_ntpd(4) policy is available, unless ntpd_flags or 1557 the ntp config file contain options that change file/dir locations. 1558 When such options (e.g., "statsdir" or "crypto") are used, ntpd can 1559 still be run as non-root by setting ntpd_user=ntpd in rc.conf, after 1560 taking steps to ensure that all required files/dirs are accessible 1561 by the ntpd user. 1562 156320180717: 1564 Big endian arm support has been removed. 1565 156620180711: 1567 The static environment setup in kernel configs is no longer mutually 1568 exclusive with the loader(8) environment by default. In order to 1569 restore the previous default behavior of disabling the loader(8) 1570 environment if a static environment is present, you must specify 1571 loader_env.disabled=1 in the static environment. 1572 157320180705: 1574 The ABI of syscalls used by management tools like sockstat and 1575 netstat has been broken to allow 32-bit binaries to work on 1576 64-bit kernels without modification. These programs will need 1577 to match the kernel in order to function. External programs may 1578 require minor modifications to accommodate a change of type in 1579 structures from pointers to 64-bit virtual addresses. 1580 158120180702: 1582 On i386 and amd64 atomics are now inlined. Out of tree modules using 1583 atomics will need to be rebuilt. 1584 158520180701: 1586 The '%I' format in the kern.corefile sysctl limits the number of 1587 core files that a process can generate to the number stored in the 1588 debug.ncores sysctl. The '%I' format is replaced by the single digit 1589 index. Previously, if all indexes were taken the kernel would overwrite 1590 only a core file with the highest index in a filename. 1591 Currently the system will create a new core file if there is a free 1592 index or if all slots are taken it will overwrite the oldest one. 1593 159420180630: 1595 Clang, llvm, lld, lldb, compiler-rt and libc++ have been upgraded to 1596 6.0.1. Please see the 20141231 entry below for information about 1597 prerequisites and upgrading, if you are not already using clang 3.5.0 1598 or higher. 1599 160020180628: 1601 r335753 introduced a new quoting method. However, etc/devd/devmatch.conf 1602 needed to be changed to work with it. This change was made with r335763 1603 and requires a mergemaster / etcupdate / etc to update the installed 1604 file. 1605 160620180612: 1607 r334930 changed the interface between the NFS modules, so they all 1608 need to be rebuilt. r335018 did a __FreeBSD_version bump for this. 1609 161020180530: 1611 As of r334391 lld is the default amd64 system linker; it is installed 1612 as /usr/bin/ld. Kernel build workarounds (see 20180510 entry) are no 1613 longer necessary. 1614 161520180530: 1616 The kernel / userland interface for devinfo changed, so you'll 1617 need a new kernel and userland as a pair for it to work (rebuilding 1618 lib/libdevinfo is all that's required). devinfo and devmatch will 1619 not work, but everything else will when there's a mismatch. 1620 162120180523: 1622 The on-disk format for hwpmc callchain records has changed to include 1623 threadid corresponding to a given record. This changes the field offsets 1624 and thus requires that libpmcstat be rebuilt before using a kernel 1625 later than r334108. 1626 162720180517: 1628 The vxge(4) driver has been removed. This driver was introduced into 1629 HEAD one week before the Exar left the Ethernet market and is not 1630 known to be used. If you have device vxge in your kernel config file 1631 it must be removed. 1632 163320180510: 1634 The amd64 kernel now requires a ld that supports ifunc to produce a 1635 working kernel, either lld or a newer binutils. lld is built by default 1636 on amd64, and the 'buildkernel' target uses it automatically. However, 1637 it is not the default linker, so building the kernel the traditional 1638 way requires LD=ld.lld on the command line (or LD=/usr/local/bin/ld for 1639 binutils port/package). lld will soon be default, and this requirement 1640 will go away. 1641 1642 NOTE: As of r334391 lld is the default system linker on amd64, and no 1643 workaround is necessary. 1644 164520180508: 1646 The nxge(4) driver has been removed. This driver was for PCI-X 10g 1647 cards made by s2io/Neterion. The company was acquired by Exar and 1648 no longer sells or supports Ethernet products. If you have device 1649 nxge in your kernel config file it must be removed. 1650 165120180504: 1652 The tz database (tzdb) has been updated to 2018e. This version more 1653 correctly models time stamps in time zones with negative DST such as 1654 Europe/Dublin (from 1971 on), Europe/Prague (1946/7), and 1655 Africa/Windhoek (1994/2017). This does not affect the UT offsets, only 1656 time zone abbreviations and the tm_isdst flag. 1657 165820180502: 1659 The ixgb(4) driver has been removed. This driver was for an early and 1660 uncommon legacy PCI 10GbE for a single ASIC, Intel 82597EX. Intel 1661 quickly shifted to the long lived ixgbe family. If you have device 1662 ixgb in your kernel config file it must be removed. 1663 166420180501: 1665 The lmc(4) driver has been removed. This was a WAN interface 1666 card that was already reportedly rare in 2003, and had an ambiguous 1667 license. If you have device lmc in your kernel config file it must 1668 be removed. 1669 167020180413: 1671 Support for Arcnet networks has been removed. If you have device 1672 arcnet or device cm in your kernel config file they must be 1673 removed. 1674 167520180411: 1676 Support for FDDI networks has been removed. If you have device 1677 fddi or device fpa in your kernel config file they must be 1678 removed. 1679 168020180406: 1681 In addition to supporting RFC 3164 formatted messages, the 1682 syslogd(8) service is now capable of parsing RFC 5424 formatted 1683 log messages. The main benefit of using RFC 5424 is that clients 1684 may now send log messages with timestamps containing year numbers, 1685 microseconds and time zone offsets. 1686 1687 Similarly, the syslog(3) C library function has been altered to 1688 send RFC 5424 formatted messages to the local system logging 1689 daemon. On systems using syslogd(8), this change should have no 1690 negative impact, as long as syslogd(8) and the C library are 1691 updated at the same time. On systems using a different system 1692 logging daemon, it may be necessary to make configuration 1693 adjustments, depending on the software used. 1694 1695 When using syslog-ng, add the 'syslog-protocol' flag to local 1696 input sources to enable parsing of RFC 5424 formatted messages: 1697 1698 source src { 1699 unix-dgram("/var/run/log" flags(syslog-protocol)); 1700 } 1701 1702 When using rsyslog, disable the 'SysSock.UseSpecialParser' option 1703 of the 'imuxsock' module to let messages be processed by the 1704 regular RFC 3164/5424 parsing pipeline: 1705 1706 module(load="imuxsock" SysSock.UseSpecialParser="off") 1707 1708 Do note that these changes only affect communication between local 1709 applications and syslogd(8). The format that syslogd(8) uses to 1710 store messages on disk or forward messages to other systems 1711 remains unchanged. syslogd(8) still uses RFC 3164 for these 1712 purposes. Options to customize this behaviour will be added in the 1713 future. Utilities that process log files stored in /var/log are 1714 thus expected to continue to function as before. 1715 1716 __FreeBSD_version has been incremented to 1200061 to denote this 1717 change. 1718 171920180328: 1720 Support for token ring networks has been removed. If you 1721 have "device token" in your kernel config you should remove 1722 it. No device drivers supported token ring. 1723 172420180323: 1725 makefs was modified to be able to tag ISO9660 El Torito boot catalog 1726 entries as EFI instead of overloading the i386 tag as done previously. 1727 The amd64 mkisoimages.sh script used to build amd64 ISO images for 1728 release was updated to use this. This may mean that makefs must be 1729 updated before "make cdrom" can be run in the release directory. This 1730 should be as simple as: 1731 1732 $ cd $SRCDIR/usr.sbin/makefs 1733 $ make depend all install 1734 173520180212: 1736 FreeBSD boot loader enhanced with Lua scripting. It's purely opt-in for 1737 now by building WITH_LOADER_LUA and WITHOUT_FORTH in /etc/src.conf. 1738 Co-existence for the transition period will come shortly. Booting is a 1739 complex environment and test coverage for Lua-enabled loaders has been 1740 thin, so it would be prudent to assume it might not work and make 1741 provisions for backup boot methods. 1742 174320180211: 1744 devmatch functionality has been turned on in devd. It will automatically 1745 load drivers for unattached devices. This may cause unexpected drivers 1746 to be loaded. Please report any problems to current@ and 1747 imp@freebsd.org. 1748 174920180114: 1750 Clang, llvm, lld, lldb, compiler-rt and libc++ have been upgraded to 1751 6.0.0. Please see the 20141231 entry below for information about 1752 prerequisites and upgrading, if you are not already using clang 3.5.0 1753 or higher. 1754 175520180110: 1756 LLVM's lld linker is now used as the FreeBSD/amd64 bootstrap linker. 1757 This means it is used to link the kernel and userland libraries and 1758 executables, but is not yet installed as /usr/bin/ld by default. 1759 1760 To revert to ld.bfd as the bootstrap linker, in /etc/src.conf set 1761 WITHOUT_LLD_BOOTSTRAP=yes 1762 176320180110: 1764 On i386, pmtimer has been removed. Its functionality has been folded 1765 into apm. It was a no-op on ACPI in current for a while now (but was 1766 still needed on i386 in FreeBSD 11 and earlier). Users may need to 1767 remove it from kernel config files. 1768 176920180104: 1770 The use of RSS hash from the network card aka flowid has been 1771 disabled by default for lagg(4) as it's currently incompatible with 1772 the lacp and loadbalance protocols. 1773 1774 This can be re-enabled by setting the following in loader.conf: 1775 net.link.lagg.default_use_flowid="1" 1776 177720180102: 1778 The SW_WATCHDOG option is no longer necessary to enable the 1779 hardclock-based software watchdog if no hardware watchdog is 1780 configured. As before, SW_WATCHDOG will cause the software 1781 watchdog to be enabled even if a hardware watchdog is configured. 1782 178320171215: 1784 r326887 fixes the issue described in the 20171214 UPDATING entry. 1785 r326888 flips the switch back to building GELI support always. 1786 178720171214: 1788 r362593 broke ZFS + GELI support for reasons unknown. However, 1789 it also broke ZFS support generally, so GELI has been turned off 1790 by default as the lesser evil in r326857. If you boot off ZFS and/or 1791 GELI, it might not be a good time to update. 1792 179320171125: 1794 PowerPC users must update loader(8) by rebuilding world before 1795 installing a new kernel, as the protocol connecting them has 1796 changed. Without the update, loader metadata will not be passed 1797 successfully to the kernel and users will have to enter their 1798 root partition at the kernel mountroot prompt to continue booting. 1799 Newer versions of loader can boot old kernels without issue. 1800 180120171110: 1802 The LOADER_FIREWIRE_SUPPORT build variable has been renamed to 1803 WITH/OUT_LOADER_FIREWIRE. LOADER_{NO_,}GELI_SUPPORT has been renamed 1804 to WITH/OUT_LOADER_GELI. 1805 180620171106: 1807 The naive and non-compliant support of posix_fallocate(2) in ZFS 1808 has been removed as of r325320. The system call now returns EINVAL 1809 when used on a ZFS file. Although the new behavior complies with the 1810 standard, some consumers are not prepared to cope with it. 1811 One known victim is lld prior to r325420. 1812 181320171102: 1814 Building in a FreeBSD src checkout will automatically create object 1815 directories now rather than store files in the current directory if 1816 'make obj' was not ran. Calling 'make obj' is no longer necessary. 1817 This feature can be disabled by setting WITHOUT_AUTO_OBJ=yes in 1818 /etc/src-env.conf (not /etc/src.conf), or passing the option in the 1819 environment. 1820 182120171101: 1822 The default MAKEOBJDIR has changed from /usr/obj/<srcdir> for native 1823 builds, and /usr/obj/<arch>/<srcdir> for cross-builds, to a unified 1824 /usr/obj/<srcdir>/<arch>. This behavior can be changed to the old 1825 format by setting WITHOUT_UNIFIED_OBJDIR=yes in /etc/src-env.conf, 1826 the environment, or with -DWITHOUT_UNIFIED_OBJDIR when building. 1827 The UNIFIED_OBJDIR option is a transitional feature that will be 1828 removed for 12.0 release; please migrate to the new format for any 1829 tools by looking up the OBJDIR used by 'make -V .OBJDIR' means rather 1830 than hardcoding paths. 1831 183220171028: 1833 The native-xtools target no longer installs the files by default to the 1834 OBJDIR. Use the native-xtools-install target with a DESTDIR to install 1835 to ${DESTDIR}/${NXTP} where NXTP defaults to /nxb-bin. 1836 183720171021: 1838 As part of the boot loader infrastructure cleanup, LOADER_*_SUPPORT 1839 options are changing from controlling the build if defined / undefined 1840 to controlling the build with explicit 'yes' or 'no' values. They will 1841 shift to WITH/WITHOUT options to match other options in the system. 1842 184320171010: 1844 libstand has turned into a private library for sys/boot use only. 1845 It is no longer supported as a public interface outside of sys/boot. 1846 184720171005: 1848 The arm port has split armv6 into armv6 and armv7. armv7 is now 1849 a valid TARGET_ARCH/MACHINE_ARCH setting. If you have an armv7 system 1850 and are running a kernel from before r324363, you will need to add 1851 MACHINE_ARCH=armv7 to 'make buildworld' to do a native build. 1852 185320171003: 1854 When building multiple kernels using KERNCONF, non-existent KERNCONF 1855 files will produce an error and buildkernel will fail. Previously 1856 missing KERNCONF files silently failed giving no indication as to 1857 why, only to subsequently discover during installkernel that the 1858 desired kernel was never built in the first place. 1859 186020170912: 1861 The default serial number format for CTL LUNs has changed. This will 1862 affect users who use /dev/diskid/* device nodes, or whose FibreChannel 1863 or iSCSI clients care about their LUNs' serial numbers. Users who 1864 require serial number stability should hardcode serial numbers in 1865 /etc/ctl.conf . 1866 186720170912: 1868 For 32-bit arm compiled for hard-float support, soft-floating point 1869 binaries now always get their shared libraries from 1870 LD_SOFT_LIBRARY_PATH (in the past, this was only used if 1871 /usr/libsoft also existed). Only users with a hard-float ld.so, but 1872 soft-float everything else should be affected. 1873 187420170826: 1875 The geli password typed at boot is now hidden. To restore the previous 1876 behavior, see geli(8) for configuration options. 1877 187820170825: 1879 Move PMTUD blackhole counters to TCPSTATS and remove them from bare 1880 sysctl values. Minor nit, but requires a rebuild of both world/kernel 1881 to complete. 1882 188320170814: 1884 "make check" behavior (made in ^/head@r295380) has been changed to 1885 execute from a limited sandbox, as opposed to executing from 1886 ${TESTSDIR}. 1887 1888 Behavioral changes: 1889 - The "beforecheck" and "aftercheck" targets are now specified. 1890 - ${CHECKDIR} (added in commit noted above) has been removed. 1891 - Legacy behavior can be enabled by setting 1892 WITHOUT_MAKE_CHECK_USE_SANDBOX in src.conf(5) or the environment. 1893 1894 If the limited sandbox mode is enabled, "make check" will execute 1895 "make distribution", then install, execute the tests, and clean up the 1896 sandbox if successful. 1897 1898 The "make distribution" and "make install" targets are typically run as 1899 root to set appropriate permissions and ownership at installation time. 1900 The end-user should set "WITH_INSTALL_AS_USER" in src.conf(5) or the 1901 environment if executing "make check" with limited sandbox mode using 1902 an unprivileged user. 1903 190420170808: 1905 Since the switch to GPT disk labels, fsck for UFS/FFS has been 1906 unable to automatically find alternate superblocks. As of r322297, 1907 the information needed to find alternate superblocks has been 1908 moved to the end of the area reserved for the boot block. 1909 Filesystems created with a newfs of this vintage or later 1910 will create the recovery information. If you have a filesystem 1911 created prior to this change and wish to have a recovery block 1912 created for your filesystem, you can do so by running fsck in 1913 foreground mode (i.e., do not use the -p or -y options). As it 1914 starts, fsck will ask ``SAVE DATA TO FIND ALTERNATE SUPERBLOCKS'' 1915 to which you should answer yes. 1916 191720170728: 1918 As of r321665, an NFSv4 server configuration that services 1919 Kerberos mounts or clients that do not support the uid/gid in 1920 owner/owner_group string capability, must explicitly enable 1921 the nfsuserd daemon by adding nfsuserd_enable="YES" to the 1922 machine's /etc/rc.conf file. 1923 192420170722: 1925 Clang, llvm, lldb, compiler-rt and libc++ have been upgraded to 5.0.0. 1926 Please see the 20141231 entry below for information about prerequisites 1927 and upgrading, if you are not already using clang 3.5.0 or higher. 1928 192920170701: 1930 WITHOUT_RCMDS is now the default. Set WITH_RCMDS if you need the 1931 r-commands (rlogin, rsh, etc.) to be built with the base system. 1932 193320170625: 1934 The FreeBSD/powerpc platform now uses a 64-bit type for time_t. This is 1935 a very major ABI incompatible change, so users of FreeBSD/powerpc must 1936 be careful when performing source upgrades. It is best to run 1937 'make installworld' from an alternate root system, either a live 1938 CD/memory stick, or a temporary root partition. Additionally, all ports 1939 must be recompiled. powerpc64 is largely unaffected, except in the case 1940 of 32-bit compatibility. All 32-bit binaries will be affected. 1941 194220170623: 1943 Forward compatibility for the "ino64" project have been committed. This 1944 will allow most new binaries to run on older kernels in a limited 1945 fashion. This prevents many of the common foot-shooting actions in the 1946 upgrade as well as the limited ability to roll back the kernel across 1947 the ino64 upgrade. Complicated use cases may not work properly, though 1948 enough simpler ones work to allow recovery in most situations. 1949 195020170620: 1951 Switch back to the BSDL dtc (Device Tree Compiler). Set WITH_GPL_DTC 1952 if you require the GPL compiler. 1953 195420170619: 1955 Forward compatibility for the "ino64" project have been committed. This 1956 will allow most new binaries to run on older kernels in a limited 1957 fashion. This prevents many of the common foot-shooting actions in the 1958 upgrade as well as the limited ability to roll back the kernel across 1959 the ino64 upgrade. Complicated use cases may not work properly, though 1960 enough simpler ones work to allow recovery in most situations. 1961 196220170618: 1963 The internal ABI used for communication between the NFS kernel modules 1964 was changed by r320085, so __FreeBSD_version was bumped to 1965 ensure all the NFS related modules are updated together. 1966 196720170617: 1968 The ABI of struct event was changed by extending the data 1969 member to 64bit and adding ext fields. For upgrade, same 1970 precautions as for the entry 20170523 "ino64" must be 1971 followed. 1972 197320170531: 1974 The GNU roff toolchain has been removed from base. To render manpages 1975 which are not supported by mandoc(1), man(1) can fallback on GNU roff 1976 from ports (and recommends to install it). 1977 To render roff(7) documents, consider using GNU roff from ports or the 1978 heirloom doctools roff toolchain from ports via pkg install groff or 1979 via pkg install heirloom-doctools. 1980 198120170524: 1982 The ath(4) and ath_hal(4) modules now build piecemeal to allow for 1983 smaller runtime footprint builds. This is useful for embedded systems 1984 which only require one chipset support. 1985 1986 If you load it as a module, make sure this is in /boot/loader.conf: 1987 1988 if_ath_load="YES" 1989 1990 This will load the HAL, all chip/RF backends and if_ath_pci. 1991 If you have if_ath_pci in /boot/loader.conf, ensure it is after 1992 if_ath or it will not load any HAL chipset support. 1993 1994 If you want to selectively load things (eg on cheaper ARM/MIPS 1995 platforms where RAM is at a premium) you should: 1996 1997 * load ath_hal 1998 * load the chip modules in question 1999 * load ath_rate, ath_dfs 2000 * load ath_main 2001 * load if_ath_pci and/or if_ath_ahb depending upon your particular 2002 bus bind type - this is where probe/attach is done. 2003 2004 For further comments/feedback, poke adrian@ . 2005 200620170523: 2007 The "ino64" 64-bit inode project has been committed, which extends 2008 a number of types to 64 bits. Upgrading in place requires care and 2009 adherence to the documented upgrade procedure. 2010 2011 If using a custom kernel configuration ensure that the 2012 COMPAT_FREEBSD11 option is included (as during the upgrade the 2013 system will be running the ino64 kernel with the existing world). 2014 2015 For the safest in-place upgrade begin by removing previous build 2016 artifacts via "rm -rf /usr/obj/*". Then, carefully follow the full 2017 procedure documented below under the heading "To rebuild everything and 2018 install it on the current system." Specifically, a reboot is required 2019 after installing the new kernel before installing world. While an 2020 installworld normally works by accident from multiuser after rebooting 2021 the proper kernel, there are many cases where this will fail across this 2022 upgrade and installworld from single user is required. 2023 202420170424: 2025 The NATM framework including the en(4), fatm(4), hatm(4), and 2026 patm(4) devices has been removed. Consumers should plan a 2027 migration before the end-of-life date for FreeBSD 11. 2028 202920170420: 2030 GNU diff has been replaced by a BSD licensed diff. Some features of GNU 2031 diff has not been implemented, if those are needed a newer version of 2032 GNU diff is available via the diffutils package under the gdiff name. 2033 203420170413: 2035 As of r316810 for ipfilter, keep frags is no longer assumed when 2036 keep state is specified in a rule. r316810 aligns ipfilter with 2037 documentation in man pages separating keep frags from keep state. 2038 This allows keep state to be specified without forcing keep frags 2039 and allows keep frags to be specified independently of keep state. 2040 To maintain previous behaviour, also specify keep frags with 2041 keep state (as documented in ipf.conf.5). 2042 204320170407: 2044 arm64 builds now use the base system LLD 4.0.0 linker by default, 2045 instead of requiring that the aarch64-binutils port or package be 2046 installed. To continue using aarch64-binutils, set 2047 CROSS_BINUTILS_PREFIX=/usr/local/aarch64-freebsd/bin . 2048 204920170405: 2050 The UDP optimization in entry 20160818 that added the sysctl 2051 net.inet.udp.require_l2_bcast has been reverted. L2 broadcast 2052 packets will no longer be treated as L3 broadcast packets. 2053 205420170331: 2055 Binds and sends to the loopback addresses, IPv6 and IPv4, will now 2056 use any explicitly assigned loopback address available in the jail 2057 instead of using the first assigned address of the jail. 2058 205920170329: 2060 The ctl.ko module no longer implements the iSCSI target frontend: 2061 cfiscsi.ko does instead. 2062 2063 If building cfiscsi.ko as a kernel module, the module can be loaded 2064 via one of the following methods: 2065 - `cfiscsi_load="YES"` in loader.conf(5). 2066 - Add `cfiscsi` to `$kld_list` in rc.conf(5). 2067 - ctladm(8)/ctld(8), when compiled with iSCSI support 2068 (`WITH_ISCSI=yes` in src.conf(5)) 2069 2070 Please see cfiscsi(4) for more details. 2071 207220170316: 2073 The mmcsd.ko module now additionally depends on geom_flashmap.ko. 2074 Also, mmc.ko and mmcsd.ko need to be a matching pair built from the 2075 same source (previously, the dependency of mmcsd.ko on mmc.ko was 2076 missing, but mmcsd.ko now will refuse to load if it is incompatible 2077 with mmc.ko). 2078 207920170315: 2080 The syntax of ipfw(8) named states was changed to avoid ambiguity. 2081 If you have used named states in the firewall rules, you need to modify 2082 them after installworld and before rebooting. Now named states must 2083 be prefixed with colon. 2084 208520170311: 2086 The old drm (sys/dev/drm/) drivers for i915 and radeon have been 2087 removed as the userland we provide cannot use them. The KMS version 2088 (sys/dev/drm2) supports the same hardware. 2089 209020170302: 2091 Clang, llvm, lldb, compiler-rt and libc++ have been upgraded to 4.0.0. 2092 Please see the 20141231 entry below for information about prerequisites 2093 and upgrading, if you are not already using clang 3.5.0 or higher. 2094 209520170221: 2096 The code that provides support for ZFS .zfs/ directory functionality 2097 has been reimplemented. It's not possible now to create a snapshot 2098 by mkdir under .zfs/snapshot/. That should be the only user visible 2099 change. 2100 210120170216: 2102 EISA bus support has been removed. The WITH_EISA option is no longer 2103 valid. 2104 210520170215: 2106 MCA bus support has been removed. 2107 210820170127: 2109 The WITH_LLD_AS_LD / WITHOUT_LLD_AS_LD build knobs have been renamed 2110 WITH_LLD_IS_LD / WITHOUT_LLD_IS_LD, for consistency with CLANG_IS_CC. 2111 211220170112: 2113 The EM_MULTIQUEUE kernel configuration option is deprecated now that 2114 the em(4) driver conforms to iflib specifications. 2115 211620170109: 2117 The igb(4), em(4) and lem(4) ethernet drivers are now implemented via 2118 IFLIB. If you have a custom kernel configuration that excludes em(4) 2119 but you use igb(4), you need to re-add em(4) to your custom 2120 configuration. 2121 212220161217: 2123 Clang, llvm, lldb, compiler-rt and libc++ have been upgraded to 3.9.1. 2124 Please see the 20141231 entry below for information about prerequisites 2125 and upgrading, if you are not already using clang 3.5.0 or higher. 2126 212720161124: 2128 Clang, llvm, lldb, compiler-rt and libc++ have been upgraded to 3.9.0. 2129 Please see the 20141231 entry below for information about prerequisites 2130 and upgrading, if you are not already using clang 3.5.0 or higher. 2131 213220161119: 2133 The layout of the pmap structure has changed for powerpc to put the pmap 2134 statistics at the front for all CPU variations. libkvm(3) and all tools 2135 that link against it need to be recompiled. 2136 213720161030: 2138 isl(4) and cyapa(4) drivers now require a new driver, 2139 chromebook_platform(4), to work properly on Chromebook-class hardware. 2140 On other types of hardware the drivers may need to be configured using 2141 device hints. Please see the corresponding manual pages for details. 2142 214320161017: 2144 The urtwn(4) driver was merged into rtwn(4) and now consists of 2145 rtwn(4) main module + rtwn_usb(4) and rtwn_pci(4) bus-specific 2146 parts. 2147 Also, firmware for RTL8188CE was renamed due to possible name 2148 conflict (rtwnrtl8192cU(B) -> rtwnrtl8192cE(B)) 2149 215020161015: 2151 GNU rcs has been removed from base. It is available as packages: 2152 - rcs: Latest GPLv3 GNU rcs version. 2153 - rcs57: Copy of the latest version of GNU rcs (GPLv2) before it was 2154 removed from base. 2155 215620161008: 2157 Use of the cc_cdg, cc_chd, cc_hd, or cc_vegas congestion control 2158 modules now requires that the kernel configuration contain the 2159 TCP_HHOOK option. (This option is included in the GENERIC kernel.) 2160 216120161003: 2162 The WITHOUT_ELFCOPY_AS_OBJCOPY src.conf(5) knob has been retired. 2163 ELF Tool Chain's elfcopy is always installed as /usr/bin/objcopy. 2164 216520160924: 2166 Relocatable object files with the extension of .So have been renamed 2167 to use an extension of .pico instead. The purpose of this change is 2168 to avoid a name clash with shared libraries on case-insensitive file 2169 systems. On those file systems, foo.So is the same file as foo.so. 2170 217120160918: 2172 GNU rcs has been turned off by default. It can (temporarily) be built 2173 again by adding WITH_RCS knob in src.conf. 2174 Otherwise, GNU rcs is available from packages: 2175 - rcs: Latest GPLv3 GNU rcs version. 2176 - rcs57: Copy of the latest version of GNU rcs (GPLv2) from base. 2177 217820160918: 2179 The backup_uses_rcs functionality has been removed from rc.subr. 2180 218120160908: 2182 The queue(3) debugging macro, QUEUE_MACRO_DEBUG, has been split into 2183 two separate components, QUEUE_MACRO_DEBUG_TRACE and 2184 QUEUE_MACRO_DEBUG_TRASH. Define both for the original 2185 QUEUE_MACRO_DEBUG behavior. 2186 218720160824: 2188 r304787 changed some ioctl interfaces between the iSCSI userspace 2189 programs and the kernel. ctladm, ctld, iscsictl, and iscsid must be 2190 rebuilt to work with new kernels. __FreeBSD_version has been bumped 2191 to 1200005. 2192 219320160818: 2194 The UDP receive code has been updated to only treat incoming UDP 2195 packets that were addressed to an L2 broadcast address as L3 2196 broadcast packets. It is not expected that this will affect any 2197 standards-conforming UDP application. The new behaviour can be 2198 disabled by setting the sysctl net.inet.udp.require_l2_bcast to 2199 0. 2200 220120160818: 2202 Remove the openbsd_poll system call. 2203 __FreeBSD_version has been bumped because of this. 2204 220520160708: 2206 The stable/11 branch has been created from head@r302406. 2207 2208After branch N is created, entries older than the N-2 branch point are removed 2209from this file. After stable/14 is branched and current becomes FreeBSD 15, 2210entries older than stable/12 branch point will be removed from current's 2211UPDATING file. 2212 2213COMMON ITEMS: 2214 2215 General Notes 2216 ------------- 2217 Sometimes, obscure build problems are the result of environment 2218 poisoning. This can happen because the make utility reads its 2219 environment when searching for values for global variables. To run 2220 your build attempts in an "environmental clean room", prefix all make 2221 commands with 'env -i '. See the env(1) manual page for more details. 2222 Occasionally a build failure will occur with "make -j" due to a race 2223 condition. If this happens try building again without -j, and please 2224 report a bug if it happens consistently. 2225 2226 When upgrading from one major version to another it is generally best to 2227 upgrade to the latest code in the currently installed branch first, then 2228 do an upgrade to the new branch. This is the best-tested upgrade path, 2229 and has the highest probability of being successful. Please try this 2230 approach if you encounter problems with a major version upgrade. Since 2231 the stable 4.x branch point, one has generally been able to upgrade from 2232 anywhere in the most recent stable branch to head / current (or even the 2233 last couple of stable branches). See the top of this file when there's 2234 an exception. 2235 2236 The update process will emit an error on an attempt to perform a build 2237 or install from a FreeBSD version below the earliest supported version. 2238 When updating from an older version the update should be performed one 2239 major release at a time, including running `make delete-old` at each 2240 step. 2241 2242 When upgrading a live system, having a root shell around before 2243 installing anything can help undo problems. Not having a root shell 2244 around can lead to problems if pam has changed too much from your 2245 starting point to allow continued authentication after the upgrade. 2246 2247 This file should be read as a log of events. When a later event changes 2248 information of a prior event, the prior event should not be deleted. 2249 Instead, a pointer to the entry with the new information should be 2250 placed in the old entry. Readers of this file should also sanity check 2251 older entries before relying on them blindly. Authors of new entries 2252 should write them with this in mind. 2253 2254 ZFS notes 2255 --------- 2256 When upgrading the boot ZFS pool to a new version (via zpool upgrade), 2257 always follow these three steps: 2258 2259 1) recompile and reinstall the ZFS boot loader and boot block 2260 (this is part of "make buildworld" and "make installworld") 2261 2262 2) update the ZFS boot block on your boot drive (only required when 2263 doing a zpool upgrade): 2264 2265 When booting on x86 via BIOS, use the following to update the ZFS boot 2266 block on the freebsd-boot partition of a GPT partitioned drive ada0: 2267 gpart bootcode -p /boot/gptzfsboot -i $N ada0 2268 The value $N will typically be 1. For EFI booting, see EFI notes. 2269 2270 3) zpool upgrade the root pool. New bootblocks will work with old 2271 pools, but not vice versa, so they need to be updated before any 2272 zpool upgrade. 2273 2274 Non-boot pools do not need these updates. 2275 2276 EFI notes 2277 --------- 2278 2279 There are two locations the boot loader can be installed into. The 2280 current location (and the default) is \efi\freebsd\loader.efi and using 2281 efibootmgr(8) to configure it. The old location, that must be used on 2282 deficient systems that don't honor efibootmgr(8) protocols, is the 2283 fallback location of \EFI\BOOT\BOOTxxx.EFI. Generally, you will copy 2284 /boot/loader.efi to this location, but on systems installed a long time 2285 ago the ESP may be too small and /boot/boot1.efi may be needed unless 2286 the ESP has been expanded in the meantime. 2287 2288 Recent systems will have the ESP mounted on /boot/efi, but older ones 2289 may not have it mounted at all, or mounted in a different 2290 location. Older arm SD images with MBR used /boot/msdos as the 2291 mountpoint. The ESP is a MSDOS filesystem. 2292 2293 The EFI boot loader rarely needs to be updated. For ZFS booting, 2294 however, you must update loader.efi before you do 'zpool upgrade' the 2295 root zpool, otherwise the old loader.efi may reject the upgraded zpool 2296 since it does not automatically understand some new features. 2297 2298 See loader.efi(8) and uefi(8) for more details. 2299 2300 To build a kernel 2301 ----------------- 2302 If you are updating from a prior version of FreeBSD (even one just 2303 a few days old), you should follow this procedure. It is the most 2304 failsafe as it uses a /usr/obj tree with a fresh mini-buildworld, 2305 2306 make kernel-toolchain 2307 make -DALWAYS_CHECK_MAKE buildkernel KERNCONF=YOUR_KERNEL_HERE 2308 make -DALWAYS_CHECK_MAKE installkernel KERNCONF=YOUR_KERNEL_HERE 2309 2310 If you are running kernel modules from ports, see FOOTNOTE [1]. 2311 2312 To test a kernel once 2313 --------------------- 2314 If you just want to boot a kernel once (because you are not sure 2315 if it works, or if you want to boot a known bad kernel to provide 2316 debugging information) run 2317 make installkernel KERNCONF=YOUR_KERNEL_HERE KODIR=/boot/testkernel 2318 nextboot -k testkernel 2319 2320 To rebuild everything and install it on the current system. 2321 ----------------------------------------------------------- 2322 # Note: sometimes if you are running current you gotta do more than 2323 # is listed here if you are upgrading from a really old current. 2324 2325 <make sure you have good level 0 dumps> [2] 2326 make buildworld 2327 <make sure any needed PORTS_MODULES are set> [1] 2328 make buildkernel KERNCONF=YOUR_KERNEL_HERE 2329 make installkernel KERNCONF=YOUR_KERNEL_HERE 2330 <reboot in single user> [3] 2331 etcupdate -p [5] 2332 make installworld 2333 etcupdate -B [4] 2334 make delete-old [6] 2335 <reboot> 2336 2337 To cross-install current onto a separate partition 2338 -------------------------------------------------- 2339 # In this approach we use a separate partition to hold 2340 # current's root, 'usr', and 'var' directories. A partition 2341 # holding "/", "/usr" and "/var" should be about 2GB in 2342 # size. 2343 2344 <make sure you have good level 0 dumps> 2345 <boot into -stable> 2346 make buildworld 2347 make buildkernel KERNCONF=YOUR_KERNEL_HERE [1] 2348 <maybe newfs current's root partition> 2349 <mount current's root partition on directory ${CURRENT_ROOT}> 2350 make installworld DESTDIR=${CURRENT_ROOT} -DDB_FROM_SRC 2351 make distribution DESTDIR=${CURRENT_ROOT} # if newfs'd 2352 make installkernel KERNCONF=YOUR_KERNEL_HERE DESTDIR=${CURRENT_ROOT} 2353 cp /etc/fstab ${CURRENT_ROOT}/etc/fstab # if newfs'd 2354 <edit ${CURRENT_ROOT}/etc/fstab to mount "/" from the correct partition> 2355 <reboot into current> 2356 <do a "native" rebuild/install as described in the previous section> 2357 <maybe install compatibility libraries from ports/misc/compat*> 2358 <reboot> 2359 2360 2361 To upgrade in-place from stable to current 2362 ---------------------------------------------- 2363 <make sure you have good level 0 dumps> [2] 2364 make buildworld [9] 2365 <make sure any needed PORTS_MODULES are set> [1] 2366 make buildkernel KERNCONF=YOUR_KERNEL_HERE [8] 2367 make installkernel KERNCONF=YOUR_KERNEL_HERE 2368 <reboot in single user> [3] 2369 etcupdate -p [5] 2370 make installworld 2371 etcupdate -B [4] 2372 make delete-old [6] 2373 <reboot> 2374 2375 Make sure that you've read the UPDATING file to understand the 2376 tweaks to various things you need. At this point in the life 2377 cycle of current, things change often and you are on your own 2378 to cope. The defaults can also change, so please read ALL of 2379 the UPDATING entries. 2380 2381 Also, if you are tracking -current, you must be subscribed to 2382 freebsd-current@freebsd.org. Make sure that before you update 2383 your sources that you have read and understood all the recent 2384 messages there. If in doubt, please track -stable which has 2385 much fewer pitfalls. 2386 2387FOOTNOTES: 2388 2389 [1] If you have third party modules, such as drm-kmod or vmware, you 2390 should disable them at this point so they don't crash your system on 2391 reboot. Alternatively, you should rebuild all the modules you have in 2392 your system and install them as well. If you are running -current, you 2393 should seriously consider placing all sources to all the modules for 2394 your system (or symlinks to them) in /usr/local/sys/modules so this 2395 happens automatically. If all your modules come from ports, then adding 2396 the port origin directories to PORTS_MODULES instead is also automatic 2397 and effective, eg: 2398 PORTS_MODULES+=graphics/drm-kmod graphics/nvidia-drm-kmod 2399 2400 [2] To make complete dumps on zfs(4), use bectl(8), which 2401 creates bootable snapshots of configurable depth that are 2402 selectable via the bootloader. For ufs(4), use dump(8) and 2403 restore(8). 2404 2405 [3] From the bootblocks, boot -s, and then do 2406 fsck -p 2407 mount -u / 2408 mount -a 2409 sh /etc/rc.d/zfs start # mount zfs filesystem, if needed 2410 cd src # full path to source 2411 adjkerntz -i # if CMOS is wall time 2412 Also, when doing a major release upgrade, it is required that you boot 2413 into single user mode to do the installworld. 2414 2415 [4] Note: This step is non-optional. Failure to do this step 2416 can result in a significant reduction in the functionality of the 2417 system. Attempting to do it by hand is not recommended and those 2418 that pursue this avenue should read this file carefully, as well 2419 as the archives of freebsd-current and freebsd-hackers mailing lists 2420 for potential gotchas. See etcupdate(8) for more information. 2421 2422 [5] Usually this step is a no-op. However, from time to time 2423 you may need to do this if you get unknown user in the following 2424 step. 2425 2426 [6] This only deletes old files and directories. Old libraries 2427 can be deleted by "make delete-old-libs", but you have to make 2428 sure that no program is using those libraries anymore. 2429 2430 [8] The new kernel must be able to run existing binaries used by an 2431 installworld. When upgrading across major versions, the new kernel's 2432 configuration must include the correct COMPAT_FREEBSD<n> option for 2433 existing binaries (e.g. COMPAT_FREEBSD11 to run 11.x binaries). Failure 2434 to do so may leave you with a system that is hard to boot to recover. A 2435 GENERIC kernel will include suitable compatibility options to run 2436 binaries from older branches. Note that the ability to run binaries 2437 from unsupported branches is not guaranteed. 2438 2439 Make sure that you merge any new devices from GENERIC since the 2440 last time you updated your kernel config file. Options also 2441 change over time, so you may need to adjust your custom kernels 2442 for these as well. 2443 2444 [9] If CPUTYPE is defined in your /etc/make.conf, make sure to use the 2445 "?=" instead of the "=" assignment operator, so that buildworld can 2446 override the CPUTYPE if it needs to. 2447 2448 MAKEOBJDIRPREFIX must be defined in an environment variable, and 2449 not on the command line, or in /etc/make.conf. buildworld will 2450 warn if it is improperly defined. 2451FORMAT: 2452 2453This file contains a list, in reverse chronological order, of major 2454breakages in tracking -current. It is not guaranteed to be a complete 2455list of such breakages, and only contains entries since September 23, 2011. 2456If you need to see UPDATING entries from before that date, you will need 2457to fetch an UPDATING file from an older FreeBSD release. 2458 2459Copyright information: 2460 2461Copyright 1998-2009 M.
