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 16.x IS SLOW: 16 FreeBSD 16.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 3020260902: 31 struct if_rxd_info now carries a receive timestamp. iflib drivers 32 must be rebuilt. __FreeBSD_version has been bumped to 1600022. 33 3420260827: 35 <sys/videoio.h> now provides the V4L2 cropping, control menu and 36 overlay definitions. __FreeBSD_version has been bumped to 1600021 37 for ports that need to detect them. 38 3920260826: 40 bhyve(8) users who explicitly set the eui64 option for an NVMe 41 device may need to update their configuration. Due to an incorrect 42 byte-order conversion, bhyve previously presented manually 43 configured EUI-64 values to the guest with their bytes reversed. 44 To preserve the identifier previously visible to the guest, 45 byte-reverse the value in the eui64 option. Automatically 46 generated EUI-64 values, used when the option is omitted, 47 are unaffected. 48 4920260814: 50 libusb version has been upgraded to 1.0.27 compatible version. 51 All of the missing parts have been implemented. 52 5320260812: 54 The new video(4) framework has landed. <sys/videoio.h> is now provided 55 as the API for communicating with it. __FreeBSD_version has been bumped 56 to 1600020 for ports that need to detect this changeover. 57 5820260728: 59 The Intel 82576 and I350 Virtual Function devices have been split from 60 the igb(4) driver into the igbv driver. Interfaces previously exposed 61 as igbN are now exposed as igbvN. Network configuration files must be 62 updated accordingly. 63 6420260727: 65 The wait_for_pids() function in rc.subr, used by rc scripts 66 when stopping or restarting a service, has been modified to 67 use pwait(1)'s new -r option, which requires kernel support. 68 When upgrading across this change, you should install a new 69 kernel first, then reboot, then install a new world, run 70 etcupdate, and reboot again. Otherwise, you may find that 71 rc.subr is unable to stop services because the running kernel 72 does not provide the support that the updated pwait(1) needs. 73 Alternatively, if you deem it safe, you may use fastboot(8) to 74 reboot without shutting down services first. 75 7620260620: 77 On powerpc64le, long double is now IEEE 754 binary128 (quad 78 precision, 113-bit mantissa) instead of 64-bit double. This is an 79 ABI-incompatible change with no symbol versioning: all C and C++ 80 code that passes, returns, or stores long double (or long double 81 complex) -- including printf/scanf "%Lf", strtold, and the libm 82 *l() routines -- must be rebuilt against the new world. Mixing old 83 and new objects that exchange long double values will silently 84 corrupt data. Rebuild all installed ports and any out-of-tree 85 software after upgrading. Big-endian powerpc and powerpc64 are 86 unaffected and keep 64-bit long double. 87 8820260521: 89 Audio devices are now created with GID 43 / audio. You will need to add 90 users who need access to audio devices to this group. 91 9220260512: 93 "bsdinstall script" will now do a pkgbase installation by default. To 94 revert to the legacy distset installation, set "DISTRIBUTIONS" in 95 your installerconfig. 96 9720260412: 98 The /etc/rc.d/NETWORKING script no longer provides the legacy 99 NETWORK alias. Third-party or local RC scripts that still use 100 "REQUIRE: NETWORK" shall be updated to use "REQUIRE: NETWORKING" 101 instead. 102 10320260129: 104 The "net.inet6.ip6.use_stableaddr" sysctl is now on by default. 105 This changes the default algorithm to choose IPv6 SLAAC autogenerated 106 addresses from embedding the interface hardware address to using 107 SHA256-HMAC hash as described in RFC 7217 to derive an opaque but 108 stable Address. If you are using autoconfigured IPv6 addresses at 109 reboot they will be different after this change, but constant 110 thereafter, please update your DNS records if any. 111 11220260106: 113 Zstd has moved to the new "zstd" package. If you have set-minimal 114 installed, this package will be installed automatically, otherwise 115 you might want to install it manually. This change only affects 116 pkgbase users. 117 11820251222: 119 Commit 9f49f436a9ec changed the internal KAPI between the NFS 120 modules. As such, nfscommon, nfscl and nfsd must all be rebuilt 121 from sources. 122 12320251212: 124 Timeouts for SCSI bus probing have been drastically reduced. They are 125 now tuneables that can be set in the boot loader should you have a 126 device that requires a longer-than-standards imply timeout but 127 none-the-less works. 128 129 kern.cam.tur_timeout (default was 60s, now 1s) 130 kern.cam.inquiry_timeout (default was 60s, now 1s) 131 kern.cam.reportluns_timeout (default is 60s) 132 kern.cam.modesense_timeout (default was 60s, now 1s) 133 13420251115: 135 The FreeBSD-base repository is now defined in /etc/pkg/FreeBSD.conf, 136 disabled by default. In -CURRENT and -STABLE this points at nightly 137 builds on pkg.freebsd.org; for BETA/RC/RELEASE builds it points at 138 release engineering builds on pkgbase.freebsd.org. 139 140 Users of pkgbase will need to replace any existing definition of the 141 FreeBSD-base repository in /usr/local/etc/pkg/repos/ with a single 142 line "FreeBSD-base: { enabled: yes }". 143 14420251110: 145 OpenPAM (including libpam and the PAM modules) has moved to the new 146 "pam" package. The pam-lib subpackage, which includes libpam, will 147 be automatically installed when required. 148 149 If you have set-minimal(-jail) installed, the pam base package which 150 contains the PAM modules will also be automatically installed. 151 If you don't, you MUST manually install the FreeBSD-pam package if you 152 need to authenticate users, otherwise you won't be able to log in. 153 154 This change only affects pkgbase users. 155 15620251105: 157 pf(4) now supports nat64 via the af-to keyword. 158 15920251102: 160 Commit e5aa60d06958 changed the internal KAPI between 161 the NFS modules. As such, they all need to be rebuilt 162 from sources. __FreeBSD_version was bumped to 1600004 for this. 163 16420251025: 165 flua(1) has moved to the new FreeBSD-flua package. If you use flua, 166 you may want to install this package if it's not otherwise installed 167 as a dependency of something else. This change only affects pkgbase 168 users. 169 17020251021: 171 Bump __FreeBSD_version to 1600002 for LinuxKPI. An embedded struct 172 has changed size and might possibly be an issue otherwise. 173 17420251016: 175 With the migration to OpenZFS in FreeBSD 13.x a number of ZFS sysctls 176 moved to new locations, but backwards compatibility aliases were 177 provided. These aliases will be removed in the near future. Please 178 update /etc/sysctl.conf to reference the new OIDs. For example, 179 180 vfs.zfs.min_auto_ashift=12 181 182 needs to be changed to 183 184 vfs.zfs.vdev.min_auto_ashift=12 185 18620251015: 187 The "FreeBSD-unbound" package is renamed to "FreeBSD-local-unbound". 188 If you have set-optional or set-base installed, the new package will 189 be installed automatically, otherwise you should manually install the 190 new package and remove the old one. 191 192 This change only affects pkgbase users. 193 19420251012: 195 Blacklist has been renamed upstream to Blocklist. If you have it 196 configured, rename all configuration files, firewall anchors or 197 sentinel files to reflect the new nomenclature. Old setups will 198 continue to work emitting a warning. 199 20020251002: 201 Audio-related utilities including mixer(8) and virtual_oss(8) have 202 moved to the new FreeBSD-sound package. If you have set-optional or 203 set-base installed this package will be installed automatically, 204 otherwise you should install it manually if you need these utilities. 205 20620250929: 207 Both drm-kmod and nividia-drm ports had to be updated to either no 208 longer conflict on LinuxKPI vs. native PCI changes and/or to keep 209 working after some LinuxKPI PCI adjustments which were previously 210 hidden behind native PCI. 211 Bump __FreeBSD_version 1600001 so users will pick up updated packages. 212 21320250929: 214 The deprecated ftpd(8) has been removed. Users who still need ftpd 215 can install the ftp/freebsd-ftpd port. pkgbase users should remove 216 the orphaned FreeBSD-ftpd package. 217 21820250923: 219 Several changes which affect pkgbase users (only): 220 221 powerd has been moved to a new FreeBSD-powerd package. If you have 222 FreeBSD-set-minimal installed, the new package will be installed 223 automatically, otherwise you may want to install it by hand. 224 225 libpmc and related utilities (/usr/sbin/pmc*) have moved to the new 226 FreeBSD-pmc package. If you use these, you may want to install the 227 package. 228 229 The libbz2 package has been renamed to bzip2, and /usr/bin/bzip2 has 230 been moved to the new package. If you have set-minimal installed, 231 the new package will be added automatically, otherwise you may want 232 to manually install it. 233 234 This only affects pkgbase users. 235 23620250918: 237 mandoc (including /usr/bin/man) has been moved to a new package, 238 FreeBSD-mandoc. If you have the minimal set installed, this package 239 will be installed automatically, otherwise you may want to install it. 240 241 Kyua has been moved to the FreeBSD-kyua package, and ATF has been moved 242 to the FreeBSD-atf* packages. If you have FreeBSD-tests installed, 243 these packages will be installed automatically, otherwise you should 244 manually install them if you need these tools. 245 246 This only affects pkgbase users. 247 24820250912: 249 If SRCCONF is unset and a file named src.conf is present at 250 the top of the source tree, it will now be used instead of 251 /etc/src.conf. 252 25320250907: 254 The MANSPLITPKG knob has been turned off by default, so pkgbase builds 255 will no longer generate "-man" subpackages; instead the manpages will 256 be shipped in the packages they belong to. If you want to continue 257 building split man packages, set WITH_MANSPLITPKG=1. 258 25920250905: 260 FreeBSD 16.0-CURRENT. 261 26220250903: 263 The BLOAT_KERNEL_WITH_EXTERR kernel config option has been renamed to 264 EXTERR_STRINGS. 265 26620250827: 267 The names of pkg repositories defined in /etc/pkg/FreeBSD.conf have 268 changed: "FreeBSD" is now "FreeBSD-ports", and "FreeBSD-kmods" is now 269 "FreeBSD-ports-kmods". Users with /usr/local/etc/pkg/repos files 270 which override these will need to adjust their configuration to match 271 the new names. 272 27320250823: 274 The set of pkgbase packages for Kerberos and OpenSSL has changed. 275 After updating past 250e77d4f0a5, you should check 'pkg orphans' 276 and remove any orphaned packages, then examine the output of 277 'pkg install -r base -g FreeBSD-openssl\* FreeBSD-kerberos\*' 278 and install any new packages you need. 279 28020250823: 281 To restore bridge(4)'s ABI compatibility with ifconfig from 14.x or 282 earlier, the size of struct ifbreq has changed, so you must update 283 the kernel and /sbin/ifconfig at the same time or you will not be 284 able to add interfaces to bridge. This is particularly important 285 if you require bridge for network access during boot, in which case 286 you should install the new kernel and the new /sbin/ifconfig prior 287 to rebooting. 288 28920250820: 290 The WITHOUT_GSSAPI src.conf knob has been removed. This was already 291 a no-op for MIT Kerberos, so this only affects builds which set 292 WITHOUT_MITKRB5=1, in which case you now always get libgssapi. 293 294 Also, Heimdal's compile_et and libcom_err are now controlled by 295 WITHOUT_KERBEROS, not WITHOUT_KERBEROS_SUPPORT. This matches 296 the behaviour of the MIT Kerberos versions. 297 29820250820: 299 Commits 08c7dd2fbe4f and a4197ea47777 have changed the ABI between 300 libvmmapi and the vmm device. If using a custom kernel configuration, 301 please ensure that the COMPAT_FREEBSD14 option is included so older 302 versions of libvmmapi continue working as expected. 303 30420250819: 305 The CLEAN option has been switched back from default-on to default-off. 306 This reverts the 20250808 change below, which had reverted the 20240729 307 change before it. Note that some src.conf(5) options are known to break 308 ABI or compatibility in ways that may require a clean build initially 309 when switched. 310 31120250816: 312 Sendmail's libmilter has been moved to its own package. If you want 313 to compile applications that use libmilter, you should install the 314 FreeBSD-libmilter* packages. 315 316 If you only have FreeBSD-sendmail installed for applications that 317 require libmilter, you can now remove it. 318 31920250815: 320 The behavior of the getgroups(2), setgroups(2), and initgroups(3) 321 interfaces has changed, and their version numbers have been incremented. 322 To keep existing binaries and libraries working, ensure that 323 COMPAT_FREEBSD14 is included in your kernel configuration. 324 Alternatively, rebuild and reinstall applications that use these 325 interfaces. 326 32720250815: 328 jemalloc 5.3.0 has been committed to the tree. 329 33020250815: 331 The removal of Secure RPC DES authentication noted in 20250810 332 has been reverted. (However, it is still non-functional.) 333 33420250813: 335 Commit cce64f2e6851 changed the internal KAPI between the NFS 336 modules. As such, all of them need to be rebuilt from sources. 337 __FreeBSD_version has been bumped to 1500060 already today, 338 so I will not bump it again for this. 339 34020250813: 341 The gpiobus_attach_bus() function has been removed. Drivers should now 342 use the gpiobus_add_bus() function instead. The difference being that 343 gpiobus_add_bus() doesn't call bus_attach_children(), calling it will 344 be the responsibility of the caller now. 345 34620250810: 347 Support for Secure RPC DES authentication has been removed. 348 The keyserv(8) daemon was already removed, but support for it in libc 349 has also been removed, so if you somehow still had keyserv installed, 350 it will now stop working. There is no workaround for this. Removing 351 DES is considered a feature. 352 35320250808: 354 The CLEAN option has been switched back from default-off to 355 default-on. This reverts the 20240729 change below. 356 35720250807: 358 routed(8) and route6d(8) have moved to the FreeBSD-rip package. 359 If you use either of these, you should install the new package. 360 36120250806: 362 if_epair(4) now uses ether_gen_addr(9) to generate a stable MAC 363 address. 364 To keep using the random address, set the loader tunable 365 net.link.epair.ether_gen_addr=0. 366 36720250804: 368 bsdconfig (including sysrc(8)) has moved to the new bsdconfig 369 package. If you use pkgbase and wish to use bsdconfig, you should 370 install FreeBSD-bsdconfig. 371 37220250730: 373 The usbhid(4) USB HID driver is now enabled by default, and will be 374 used in preference to other USB HID drivers like ukbd(4), ums(4), and 375 uhid(4). Work on a FIDO/U2F driver and moused(8) is in progress. 376 The default is being switched now so that we can find and fix any 377 additional issues prior to FreeBSD 15.0. 378 379 To revert to the previous USB HID driver behavior, set the loader 380 tunable hw.usb.usbhid.enable=0. 381 38220250727: 383 bmake (i.e., /usr/bin/make and /usr/share/mk) has moved to a new 384 package, FreeBSD-bmake. If you use pkgbase and you need make, you 385 should install this package. 386 38720250726: 388 amd64 kernel configurations must contain "options SMP". 389 39020250725: 391 gssd(8) has been moved to a new package, FreeBSD-gssd. If you use 392 pkgbase and you need gssd, you should install this package. 393 39420250724: 395 The Kerberos packages which are built when WITH_MITKRB5 is enabled 396 have been renamed from FreeBSD-krb5* to FreeBSD-kerberos*. This 397 affects pkgbase users who manually enabled WITH_MITKRB5, *or* use 398 the default value of WITH_MITKRB5 and updated past c7da9fb90b0b 399 (20250721) which made WITH_MITKRB5 the default. 400 401 In either case, if you have FreeBSD-krb5* packages installed, you 402 should remove them and (re)install the equivalent FreeBSD-kerberos* 403 packages instead. 404 40520250721: 406 WITH_MITKRB5 is now enabled by default. MIT KRB5 has replaced 407 Heimdal in base. Ports that use USES=gssapi must be rebuilt. 408 A clean buildworld is required. 409 41020250719: 411 Commits 392a82b225 and c00baac0ab both changed the 412 internal API between the NFS modules. As such, all 413 these modules need to be rebuilt from sources. 414 __FreeBSD_version was bumped to 1500053 for this. 415 41620250710: 417 The shar(1) utility has been removed from base. The 418 sysutils/freebsd-shar port was created to maintain this version of 419 shar(1) past its removal from base. 420 42120250704: 422 LinuxKPI device.h and acpi changes effecting drivers and drm-kmod. 423 Bump __FreeBSD_version 1500050 to be able to detect these changes. 424 42520250630: 426 Commits 171f66b0c2ca and 8e2a90ac8089 changed the internal 427 api between nfscommon.ko and the other nfs modules. 428 Bump __FreeBSD_version to 1500049 for this. 429 All NFS related modules must be rebuilt from up-to-date 430 sources. 431 43220250625: 433 "make delete-old" will now remove the Forth bootloader entirely 434 if the system is built with WITHOUT_FORTH. 435 43620250614: 437 MIT KRB5 (MIT Kerberos5) has been imported into 15-CURRENT. To 438 and install MIT KRB5, add WITH_MITKRB5=yes to /etc/src.conf. This 439 will build and install MIT KRB5 1.21.3. And it will remove Heimdal 440 1.5.2 when delete-old and delete-old-libs are run. To revert back 441 simply buildworld/installworld again with delete-old-libs and 442 delete-old. 443 444 At the moment we only know of a couple of ports that might be 445 affected. Adjusting libmap.conf does not circumvent runtime issues. 446 The few affected ports must be rebuilt. A successful exp-run will be 447 run before MIT KRB5 becomes default. 448 449 Those using the KDC in FreeBSD base may wish to wait. The Heimdal 450 HDB is incompatible with the MIT KRB5 KDC. The migration procedure 451 is a little involved. 452 45320250603: 454 LinuxKPI dma-mapping.h were pulled into the tree from drm-kmod. 455 Bump _FreeBSD_version to 1500045 to be able to detect this change. 456 45720250527: 458 pf changed extension header handling. It now treats AH headers on IPv4 just 459 like AH headers on IPv6 and skips over them, allowing filtering on the inner 460 protocol. 461 46220250527: 463 pf now blocks IPv6 packets with a hop-by-hop or destination options header by 464 default. Such packets can be passed by adding "allow-opts" to the rule. IPv6 465 options are now handled just like their IPv4 counterparts. 466 46720250527: 468 The CAM target layer userland, i.e. ctld(8), ctladm(8) and ctlstat(8), 469 has moved to the new FreeBSD-ctl package. If you use pkgbase and you 470 need the CAM Target Layer, you should install the new package. 471 472 Development-related tools (e.g. ar and nm) have moved to the new 473 "FreeBSD-toolchain" package, which subsumes and obsoletes the 474 existing "FreeBSD-elftoolchain" package. If you use pkgbase and 475 need to compile software, you should install the new package and 476 ensure the old FreeBSD-elftoolchain* packages are completely removed. 477 47820250521: 479 Commit e64fe5ad3a23 removed in6_maxmtu and its setter in6_setmaxmtu(). 480 in6_maxmtu is used to store the max IPv6 MTU of all interfaces, 481 however it does not have any in-tree consumers since the introduction 482 from the KAME project. The removal should have little impact, and the 483 max IPv6 MTU can be easily retrieved by iterating over all the attached 484 interface if 3rd party modules need it. 485 48620250515: 487 Commit 772258c89f28 changed the internal API between the nfscommon 488 and nfscl modules. Both need to be built from updated sources. 489 49020250513: 491 The bridge(4) sysctl net.link.bridge.member_ifaddrs now defaults to 0, 492 meaning that interfaces added to a bridge may not have IP addresses 493 assigned. Refer to bridge(4) for more information. 494 49520250507: 496 UMASS quirks and auto-quirk probing has been overhauled. CAM now won't 497 send SYNCHRONIZE CACHE unless MODE PAGE 8 is present and valid. This 498 should allow more devices to work (since the auto quirk code was updated 499 in 14 and broke several e-readers and the like). Please send imp@freebsd.org 500 any regression reports. 501 50220250504: 503 Commit 9419e086e1a3 changed the internal API between the nfscommon 504 and nfscl modules. Both need to be built from updated sources. 505 50620250412: 507 LinuxKPI alloc routines were changed to return physically contiguous 508 memory where expected. These changes may require out-of-tree drivers 509 to be recompiled. 510 Bump __FreeBSD_version to 1500037 to be able to detect this change. 511 51220250409: 513 Intel iwlwifi firmware has been removed from the src repository. 514 Before updating their system, users of iwlwifi(4) or iwx(4) must 515 install the appropriate firmware for their chipset using fwget(8) or 516 building it from ports. 517 51820250314: 519 We now use LLVM's binary utilities (nm, objcopy, etc.) by default. 520 The WITHOUT_LLVM_BINUTILS src.conf(5) knob can be used to revert to 521 ELF Tool Chain tools if desired. 522 52320250303: 524 Commit 4a77657cbc01 changed the ABI between ipfw(8) and ipfw(4). 525 Please note that the old ipfw(8) binary will not work with the new 526 ipfw(4) module. Therefore, it is recommended to disable ipfw during 527 the upgrade, otherwise the host system may become inaccessible because 528 ipfw rules cannot be installed with the old binary. 529 53020250214: 531 Commit 4517fbfd4251 modified the internal API between the 532 nfscommon and nfscl modules. As such, both of these modules 533 need to be rebuilt from sources. 534 53520250201: 536 The NFS related daemons, that provide RPC services to the kernel: 537 gssd(8), rpcbind(8), rpc.tlsservd(8) and rpc.tlsclntd(8), now use a 538 different transport - netlink(4) socket instead of unix(4). Users of 539 NFS need to upgrade both kernel and world (binaries and libc) at once. 540 Also, any revision between 88cd1e17a7d8 and 99e5a70046da should be 541 avoided. 542 54320250129: 544 Defer the January 19, 2038 date limit in UFS1 filesystems to 545 February 7, 2106. This affects only UFS1 format filesystems. 546 See commit message 1111a44301da for details. 547 54820250127: 549 The Allwinner a10_timer driver has been renamed to aw_driver. If you 550 have a custom kernel configuration including the line 'device 551 a10_timer', it must be adjusted to 'device aw_timer'. The same applies 552 for device exclusions with 'nodevice'. 553 55420250106: 555 A new SOC_ROCKCHIP options appeared, so if you have a custom kernel configuration 556 targeting Rockchip SoC you need to add it so shared and mandatory drivers for 557 this SoC family will be selected. 558 Also a new rk8xx device was added, this select the base driver for Rockchip PMIC. 559 56020241223: 561 The layout of NFS file handles for the tarfs, tmpfs, cd9660, and ext2fs 562 file systems has changed. An NFS server that exports any of these file 563 systems will need its clients to unmount and remount the exports. 564 56520241216: 566 The iwm(4) firmwares are no longer compiled as kernel modules but instead 567 shipped as raw files. For pkgbase users if you use iwm(4) you will need 568 to install the FreeBSD-firmware-iwm package. 569 57020241124: 571 The OpenBSD derived bc and dc implementations and the WITHOUT_GH_BC 572 option that allowed building them instead of the advanced version 573 imported more than 4 years ago have been removed. 574 57520241107: 576 The ng_ubt(4) driver now requires firmwares to be loaded on Realtek 577 adaptors with rtlbtfw(8) utility. It no longer attaches to devices 578 standing in bootloader mode. Firmware files are available in the 579 comms/rtlbt-firmware port. 580 58120241025: 582 The support for the rc_fast_and_loose variable has been removed from 583 rc.subr(8). Users setting rc_fast_and_loose on their systems are 584 advised to make sure their customizations to rc service scripts 585 do not depend on having a single shell environment shared across 586 all the rc service scripts during booting and shutdown. 587 58820241013: 589 The ciss driver was updated to cope better with hotplug events that 590 caused it to panic before, and to support more than 48 drives attached 591 to the card. These changes were made w/o benefit of hardware for testing 592 and ciss(4) users should be on the lookout for regressions. 593 59420240729: 595 The build now defaults to WITHOUT_CLEAN - i.e., no automatic clean 596 is performed at the beginning of buildworld or buildkernel. The 597 WITH_CLEAN src.conf(5) knob can be used to restore the previous 598 behaviour. 599 600 If you encounter incremental build issues, please report them to the 601 freebsd-current mailing list so that a special-case dependency can be 602 added, if necessary. 603 60420240715: 605 We now lean more heavily on ACPI enumeration for some traditional 606 devices. uart has moved from isa to acpi so the hints act as wiring 607 instead of device enumeration. Hints for parallel port, floppy, etc 608 have been removed. Before upgrading, grep your dmesg for lines like: 609 uart1: non-PNP ISA device will be removed from GENERIC in FreeBSD 15. 610 to see if you need to start including hints for the device on isa 611 in your loader.conf or device.hints file. APU1 (but not APU2) boards 612 are known to be affected, but there may be others. 613 61420240712: 615 Support for armv6 has been disconnected and is being removed. 616 61720240617: 618 ifconfig now treats IPv4 addresses without a width or mask as an error. 619 Specify the desired mask or width along with the IP address on the 620 ifconfig command line and in rc.conf. 621 62220240428: 623 OpenBSM auditing runtime (auditd, etc.) has been moved into the new 624 package FreeBSD-audit. If you use OpenBSM auditing and pkgbase, you 625 should install FreeBSD-audit. 626 62720240424: 628 cron, lpr, and ntpd have been moved from FreeBSD-utilities into their 629 own packages. If you use pkgbase, you should install the relevant 630 packages: FreeBSD-cron, FreeBSD-lp, or FreeBSD-ntp. 631 63220240406: 633 Clang, llvm, lld, lldb, compiler-rt, libc++, libunwind and openmp have 634 been upgraded to 18.1.6. It is important that you run `make delete-old` 635 as described in the COMMON ITEMS section, otherwise several libc++ 636 headers that are obsolete and need to be removed can cause compilation 637 errors in C++ programs. 638 63920240205: 640 For dynamically linked programs, system calls are now made from 641 libsys rather than libc. No change in linkage is required as 642 libsys is an auxiliary filter for libc. People building custom 643 images must ensure that libsys.so.7 is included. 644 64520240202: 646 Loader now also read configuration files listed in local_loader_conf_files. 647 Files listed here are the last ones read. And /boot/loader.conf.local was 648 moved from loader_conf_files to local_loader_conf_files leaving only 649 loader.conf and device.hints in loader_conf_files by default. 650 651 The following sequencing is applied: 652 653 1. Bootstrap: 654 /boot/defaults/loader.conf 655 656 2. Read loader_conf_files files: 657 /boot/device.hints 658 /boot/loader.conf 659 660 3. Read loader_conf_dirs files: 661 /boot/loader.conf.d/*.conf 662 663 4. And finally, rread local_loader_conf_files files: 664 /boot/loader.conf.local 665 66620240201: 667 sendmail 8.18.1 has been imported and merged. This version enforces 668 stricter RFC compliance by default, especially with respect to line 669 endings. This may cause issues with receiving messages from 670 non-compliant MTAs; please see the first 8.18.1 release note in 671 contrib/sendmail/RELEASE_NOTES for mitigations. 672 67320240111: 674 Commit cc760de2183f changed the internal interface between 675 the nfscommon and nfscl modules. As such, both need to be 676 rebuilt from sources. Therefore, __FreeBSD_version was 677 bumped to 1500010. 678 67920231120: 680 If you have an arm64 system that uses ACPI, you will need to update your 681 loader.efi in the ESP when you update past this point. Detection of ACPI 682 was moved earlier in the binary so the scripts could use it, but old 683 binaries don't have this, so we default to 'no ACPI' in this case. You can 684 undisable ACPI by doing 685 OK unset hint.acpi.0.disabled 686 This can also be used to recover any other system that was updated in the 687 small window where amd64 was also broken. 688 68920231113: 690 The WITHOUT_LLD_IS_LD option has been removed. When LLD is enabled 691 it is always installed as /usr/bin/ld. 692 69320231027: 694 Forward compatibility (running the new code on old kernels) for the 695 "ino64" project have been removed. The need for it has passed long ago. 696 69720231018: 698 Commit 57ce37f9dcd0 changed the internal KAPI between the 699 nfscommon and nfscl modules. Both must be rebuilt from sources. 700 70120231010: 702 dialog(1) has been replaced in base by bsddialog(1), while most of the 703 time replacing a dialog(1) call by a bsddialog(1) call works out of the 704 box, bsddialog(1) is not considered as a drop-in replacement for 705 dialog(1). 706 707 If you do depend on dialog(1) functionality, please install cdialog 708 from ports: 709 710 pkg install cdialog 711 71220230927: 713 The EARLY_AP_STARTUP kernel option is mandatory on x86. The option 714 has been added to DEFAULTS, so it should automatically be included in 715 custom kernel configurations without any additional change. 716 71720230922: 718 A new loader tunable net.pf.default_to_drop allows pf(4)’s default 719 behaviour to be changed from pass to drop. Previously this required 720 recompiling the kernel with the option PF_DEFAULT_TO_DROP. 721 72220230914: 723 Enable splitting out pkgbase manpages into separate packages by 724 default. To disable this, set WITHOUT_MANSPLITPKG=yes in src.conf. 725 72620230911: 727 Move standard include files to the clibs-dev package and move clang 728 internal libraries and headers to clang and clang-dev. Upgrading systems 729 installed using pkgbase past this change involves extra steps to allow 730 for these file moves: 731 732 pkg upgrade -y FreeBSD-utilities 733 pkg upgrade -y FreeBSD-utilities-dev 734 pkg upgrade -y 735 73620230909: 737 Enable vnet sysctl variables to be loader tunable. SYSCTLs which 738 belongs to VNETs can be initialized during early boot or module 739 loading if they are marked with CTLFLAG_TUN and there are 740 corresponding kernel environment variables. 741 74220230901: 743 The WITH_INIT_ALL_PATTERN and WITH_INIT_ALL_ZERO build options have 744 been replaced by INIT_ALL=pattern and INIT_ALL=zero respectively. 745 74620230824: 747 FreeBSD 15.0-CURRENT. 748 74920230817: 750 Serial communication (in boot loaders, kernel, and userland) has 751 been changed to default to 115200 bps, in line with common industry 752 practice and typical firmware serial console redirection 753 configuration. 754 755 Note that the early x86 BIOS bootloader (i.e., boot0sio) does not 756 support rates above 9600 bps and is not changed. boot0sio users may 757 set BOOT_COMCONSOLE_SPEED=9600 to use 9600 for all of the boot 758 components, or use the standard boot0 and have the boot2 stage start 759 with the serial port at 115200. 760 76120230807: 762 Following the general removal of MIPS support, the ath(4) AHB bus- 763 frontend has been removed, too, and building of the PCI support is 764 integrated with the ath(4) main module again. As a result, there's 765 no longer a need for if_ath_pci_load="YES" in /boot/loader.conf or 766 "device ath_pci" in the kernel configuration. 767 76820230803: 769 MAXCPU has been increased to 1024 in the amd64 GENERIC kernel config. 770 Out-of-tree kernel modules will need to be rebuilt. 771 77220230724: 773 CAM has been mechanically updated s/u_int(64|32|16|8)_t/uint\1_t/g 774 to move to the standard uintXX_t types from the old, traditional 775 BSD u_intXX_t types. This should be a NOP, but may cause problems 776 for out of tree changes. The SIMs were not updated since most of 777 the old u_intXX_t uses weren't due to CAM interfaces. 778 77920230713: 780 stable/14 branch created. 781 78220230629: 783 The heuristic for detecting old chromebooks with an EC bug that requires 784 atkbdc driver workarounds has changed. There should be no functional 785 change, but if your old chromebook's keyboard stops working, please 786 file a PR and assign it to imp. 787 78820230623: 789 OpenSSL has been updated to version 3.0, including changes throughout 790 the base system. It is important to rebuild third-party software 791 after upgrading. 792 79320230619: 794 To enable pf rdr rules for connections initiated from the host, pf 795 filter rules can be optionally enabled for packets delivered 796 locally. This can change the behavior of rules which match packets 797 delivered to lo0. To enable this feature: 798 799 sysctl net.pf.filter_local=1 800 service pf restart 801 802 When enabled, its best to ensure that packets delivered locally are not 803 filtered, e.g. by adding a 'skip on lo' rule. 804 80520230613: 806 Improvements to libtacplus(8) mean that tacplus.conf(5) now 807 follows POSIX shell syntax rules. This may cause TACACS+ 808 authentication to fail if the shared secret contains a single 809 quote, double quote, or backslash character which isn't 810 already properly quoted or escaped. 811 81220230612: 813 Belatedly switch the default nvme block device on x86 from nvd to nda. 814 nda created nvd compatibility links by default, so this should be a 815 nop. If this causes problems for your application, set hw.nvme.use_nvd=1 816 in your loader.conf or add `options NVME_USE_NVD=1` to your kernel 817 config. To disable the nvd compatibility aliases, add 818 kern.cam.nda.nvd_compat=0 to loader.conf. The default has been nda on 819 all non-x86 platforms for some time now. If you need to fall back, 820 please email imp@freebsd.org about why. 821 822 Encrypted swap partitions need to be changed from nvd to nda if you 823 migrate, or you need to use the above to switch back to nvd. 824 82520230422: 826 Remove portsnap(8). Users are encouraged to obtain the ports tree 827 using git instead. 828 82920230420: 830 Add jobs.mk to save typing. Enables -j${JOB_MAX} and logging 831 eg. 832 make buildworld-jobs 833 runs 834 make -j${JOB_MAX} buildworld > ../buildworld.log 2>&1 835 836 where JOB_MAX is derived from ncpus in local.sys.mk if not set in env. 837 83820230316: 839 Video related devices for some arm devices have been renamed. 840 If you have a custom kernel config and want to use hdmi output on 841 IMX6 board you need to add "device dwc_hdmi" "device imx6_hdmi" and 842 "device imx6_ipu" to it. 843 If you have a custom kernel config and want to use hdmi output on 844 TI AM335X board you need to add "device tda19988" to it. 845 If you add "device hdmi" in it you need to remove it as it doesn't 846 exist anymore. 847 84820230221: 849 Introduce new kernel options KBD_DELAY1 and KBD_DELAY2. See atkbdc(4) 850 for details. 851 85220230206: 853 sshd now defaults to having X11Forwarding disabled, following upstream. 854 Administrators who wish to enable X11Forwarding should add 855 `X11Forwarding yes` to /etc/ssh/sshd_config. 856 85720230204: 858 Since commit 75d41cb6967 Huawei 3G/4G LTE Mobile Devices do not default 859 to ECM, but NCM mode and need u3g and ucom modules loaded. See cdce(4). 860 86120230130: 862 As of commit 7c40e2d5f685, the dependency on netlink(4) has been added 863 to the linux_common(4) module. Users relying on linux_common may need 864 to compile netlink(4) module if it is not present in their kernel. 865 86620230126: 867 The WITHOUT_CXX option has been removed. C++ components in the base 868 system are now built unconditionally. 869 87020230113: 871 LinuxKPI pci.h changes may require out-of-tree drivers to be recompiled. 872 Bump _FreeBSD_version to 1400078 to be able to detect this change. 873 87420221212: 875 llvm-objdump is now always installed as objdump. Previously there was 876 no /usr/bin/objdump unless the WITH_LLVM_BINUTILS knob was used. 877 878 Some LLVM objdump options have a different output format compared to 879 GNU objdump; readelf is available for inspecting ELF files, and GNU 880 objdump is available from the devel/binutils port or package. 881 88220221205: 883 dma(8) has replaced sendmail(8) as the default mta. For people willing 884 to re-enable sendmail(8): 885 886 $ cp /usr/share/examples/sendmail/mailer.conf /etc/mail/mailer.conf 887 888 and add sendmail_enable="YES" to rc.conf. 889 89020221204: 891 hw.bus.disable_failed_devices has changed from 'false' to 'true' by 892 default. Now if newbus succeeds in probing a device, but fails to attach 893 the device, we'll disable the device. In the past, we'd keep retrying 894 the device on each new driver loaded. To get that behavior now, one 895 needs to use devctl to re-enable the device, and reprobe it (or set 896 the sysctl/tunable hw.bus.disable_failed_devices=false). 897 898 NOTE: This was reverted 20221205 due to unexpected compatibility issues 899 90020221122: 901 pf no longer accepts 'scrub fragment crop' or 'scrub fragment drop-ovl'. 902 These configurations are no longer automatically reinterpreted as 903 'scrub fragment reassemble'. 904 90520221121: 906 The WITHOUT_CLANG_IS_CC option has been removed. When Clang is enabled 907 it is always installed as /usr/bin/cc (and c++, cpp). 908 90920221026: 910 Some programs have been moved into separate packages. It is recommended 911 for pkgbase users to do: 912 913 pkg install FreeBSD-dhclient FreeBSD-geom FreeBSD-resolvconf \ 914 FreeBSD-devd FreeBSD-devmatch 915 916 after upgrading to restore all the component that were previously 917 installed. 918 91920221002: 920 OPIE has been removed from the base system. If needed, it can 921 be installed from ports (security/opie) or packages (opie). 922 Otherwise, make sure that your PAM policies do not reference 923 pam_opie or pam_opieaccess. 924 92520220610: 926 LinuxKPI pm.h changes require an update to the latest drm-kmod version 927 before re-compiling to avoid errors. 928 92920211230: 930 The macros provided for the manipulation of CPU sets (e.g. CPU_AND) 931 have been modified to take 2 source arguments instead of only 1. 932 Externally maintained sources that use these macros will have to 933 be adapted. The FreeBSD version has been bumped to 1400046 to 934 reflect this change. 935 93620211214: 937 A number of the kernel include files are able to be included by 938 themselves. A test has been added to buildworld to enforce this. 939 94020211209: 941 Remove mips as a recognized target. This starts the decommissioning of 942 mips support in FreeBSD. mips related items will be removed wholesale in 943 the coming days and weeks. 944 945 This broke the NO_CLEAN build for some people. Either do a clean build 946 or touch 947 lib/clang/include/llvm/Config/Targets.def 948 lib/clang/include/llvm/Config/AsmParsers.def 949 lib/clang/include/llvm/Config/Disassemblers.def 950 lib/clang/include/llvm/Config/AsmPrinters.def 951 before the build to force everything to rebuild that needs to. 952 95320211202: 954 Unbound support for RFC8375: The special-use domain 'home.arpa' is 955 by default blocked. To unblock it use a local-zone nodefault 956 statement in unbound.conf: 957 local-zone: "home.arpa." nodefault 958 959 Or use another type of local-zone to override with your choice. 960 961 The reason for this is discussed in Section 6.1 of RFC8375: 962 Because 'home.arpa.' is not globally scoped and cannot be secured 963 using DNSSEC based on the root domain's trust anchor, there is no way 964 to tell, using a standard DNS query, in which homenet scope an answer 965 belongs. Consequently, users may experience surprising results with 966 such names when roaming to different homenets. 967 96820211118: 969 Mips has been removed from universe builds. It will be removed from the 970 tree shortly. 971 97220211110: 973 Commit b8d60729deef changed the TCP congestion control framework so 974 that any of the included congestion control modules could be 975 the single module built into the kernel. Previously newreno 976 was automatically built in through direct reference. As of 977 this commit you are required to declare at least one congestion 978 control module (e.g. 'options CC_NEWRENO') and to also declare a 979 default using the CC_DEFAULT option (e.g. options CC_DEFAULT="newreno\"). 980 The GENERIC configuration includes CC_NEWRENO and defines newreno 981 as the default. If no congestion control option is built into the 982 kernel and you are including networking, the kernel compile will 983 fail. Also if no default is declared the kernel compile will fail. 984 98520211106: 986 Commit f0c9847a6c47 changed the arguments for VOP_ALLOCATE. 987 The NFS modules must be rebuilt from sources and any out 988 of tree file systems that implement their own VOP_ALLOCATE 989 may need to be modified. 990 99120211022: 992 The synchronous PPP kernel driver sppp(4) has been removed. 993 The cp(4) and ce(4) drivers are now always compiled with netgraph(4) 994 support, formerly enabled by NETGRAPH_CRONYX option. 995 99620211020: 997 sh(1) is now the default shell for the root user. To force root to use 998 the csh shell, please run the following command as root: 999 1000 # chsh -s csh 1001 100220211004: 1003 Ncurses distribution has been split between libtinfow and libncurses 1004 with libncurses.so becoming a linker (ld) script to seamlessly link 1005 to libtinfow as needed. Bump _FreeBSD_version to 1400035 to reflect 1006 this change. 1007 100820210923: 1009 As of commit 8160a0f62be6, the dummynet module no longer depends on the 1010 ipfw module. Dummynet can now be used by pf as well as ipfw. As such 1011 users who relied on this dependency may need to include ipfw in the 1012 list of modules to load on their systems. 1013 101420210922: 1015 As of commit 903873ce1560, the mixer(8) utility has got a slightly 1016 new syntax. Please refer to the mixer(8) manual page for more 1017 information. The old mixer utility can be installed from ports: 1018 audio/freebsd-13-mixer 1019 102020210911: 1021 As of commit 55089ef4f8bb, the global variable nfs_maxcopyrange has 1022 been deleted from the nfscommon.ko. As such, nfsd.ko must be built 1023 from up to date sources to avoid an undefined reference when 1024 being loaded. 1025 102620210817: 1027 As of commit 62ca9fc1ad56 OpenSSL no longer enables kernel TLS 1028 by default. Users can enable kernel TLS via the "KTLS" SSL 1029 option. This can be enabled globally by using a custom 1030 OpenSSL config file via OPENSSL_CONF or via an 1031 application-specific configuration option for applications 1032 which permit setting SSL options via SSL_CONF_cmd(3). 1033 103420210811: 1035 Commit 3ad1e1c1ce20 changed the internal KAPI between the NFS 1036 modules. Therefore, all need to be rebuilt from sources. 1037 103820210730: 1039 Commit b69019c14cd8 removes pf's DIOCGETSTATESNV ioctl. 1040 As of be70c7a50d32 it is no longer used by userspace, but it does mean 1041 users may not be able to enumerate pf states if they update the kernel 1042 past b69019c14cd8 without first updating userspace past be70c7a50d32. 1043 104420210729: 1045 As of commit 01ad0c007964 if_bridge member interfaces can no longer 1046 change their MTU. Changing the MTU of the bridge itself will change the 1047 MTU on all member interfaces instead. 1048 104920210716: 1050 Commit ee29e6f31111 changed the internal KAPI between the nfscommon 1051 and nfsd modules. Therefore, both need to be rebuilt from sources. 1052 Bump __FreeBSD_version to 1400026 for this KAPI change. 1053 105420210715: 1055 The 20210707 awk update brought in a change in behavior. This has 1056 been corrected as of d4d252c49976. Between these dates, if you 1057 installed a new awk binary, you may not be able to build a new 1058 kernel because the change in behavior affected the genoffset 1059 script used to build the kernel. If you did update, the fix is 1060 to update your sources past the above hash and do 1061 % cd usr.bin/awk 1062 % make clean all 1063 % sudo -E make install 1064 to enable building kernels again. 1065 106620210708: 1067 Commit 1e0a518d6548 changed the internal KAPI between the NFS 1068 modules. They all need to be rebuilt from sources. I did not 1069 bump __FreeBSD_version, since it was bumped recently. 1070 107120210707: 1072 awk has been updated to the latest one-true-awk version 20210215. 1073 This contains a number of minor bug fixes. 1074 107520210624: 1076 The NFSv4 client now uses the highest minor version of NFSv4 1077 supported by the NFSv4 server by default instead of minor version 0, 1078 for NFSv4 mounts. 1079 The "minorversion" mount option may be used to override this default. 1080 108120210618: 1082 Bump __FreeBSD_version to 1400024 for LinuxKPI changes. 1083 Most notably netdev.h can change now as the (last) dependencies 1084 (mlx4/ofed) are now using struct ifnet directly, but also for PCI 1085 additions and others. 1086 108720210618: 1088 The directory "blacklisted" under /usr/share/certs/ has been 1089 renamed to "untrusted". 1090 109120210611: 1092 svnlite has been removed from base. Should you need svn for any reason 1093 please install the svn package or port. 1094 109520210611: 1096 Commit e1a907a25cfa changed the internal KAPI between the krpc 1097 and nfsserver. As such, both modules must be rebuilt from 1098 sources. Bump __FreeBSD_version to 1400022. 1099 110020210610: 1101 The an(4) driver has been removed from FreeBSD. 1102 110320210608: 1104 The vendor/openzfs branch was renamed to vendor/openzfs/legacy to 1105 start tracking OpenZFS upstream more closely. Please see 1106https://lists.freebsd.org/archives/freebsd-current/2021-June/000153.html 1107 for details on how to correct any errors that might result. The 1108 short version is that you need to remove the old branch locally: 1109 git update-ref -d refs/remotes/freebsd/vendor/openzfs 1110 (assuming your upstream origin is named 'freebsd'). 1111 111220210525: 1113 Commits 17accc08ae15 and de102f870501 add new files to LinuxKPI 1114 which break drm-kmod. In addition various other additions where 1115 committed. Bump __FreeBSD_version to 1400015 to be able to 1116 detect this. 1117 111820210513: 1119 Commit ca179c4d74f2 changed the package in which the OpenSSL 1120 libraries and utilities are packaged. 1121 It is recommended for pkgbase user to do: 1122 pkg install -f FreeBSD-openssl 1123 before pkg upgrade otherwise some dependencies might not be met 1124 and pkg will stop working as libssl will not be present anymore 1125 on the system. 1126 112720210426: 1128 Commit 875977314881 changed the internal KAPI between 1129 the nfsd and nfscommon modules. As such these modules 1130 need to be rebuilt from sources. 1131 Without this patch in your NFSv4.1/4.2 server, enabling 1132 delegations by setting vfs.nfsd.issue_delegations non-zero 1133 is not recommended. 1134 113520210411: 1136 Commit 7763814fc9c2 changed the internal KAPI between 1137 the krpc and NFS. As such, the krpc, nfscommon and 1138 nfscl modules must all be rebuilt from sources. 1139 Without this patch, NFSv4.1/4.2 mounts should not 1140 be done with the nfscbd(8) daemon running, to avoid 1141 needing a working back channel for server->client RPCs. 1142 114320210330: 1144 Commit 01ae8969a9ee fixed the NFSv4.1/4.2 server so that it 1145 handles binding of the back channel as required by RFC5661. 1146 Until this patch is in your server, avoid use of the "nconnects" 1147 mount option for Linux NFSv4.1/4.2 mounts. 1148 114920210225: 1150 For 64-bit architectures the base system is now built with Position 1151 Independent Executable (PIE) support enabled by default. It may be 1152 disabled using the WITHOUT_PIE knob. A clean build is required. 1153 115420210128: 1155 Various LinuxKPI functionality was added which conflicts with DRM. 1156 Please update your drm-kmod port to after the __FreeBSD_version 1400003 1157 update. 1158 115920210121: 1160 stable/13 branch created. 1161 116220210108: 1163 PC Card attachments for all devices have been removed. In the case of 1164 wi and cmx, the entire drivers were removed because they were only 1165 PC Card devices. FreeBSD_version 1300134 should be used for this 1166 since it was bumped so recently. 1167 116820210107: 1169 Transport-independent parts of HID support have been split off the USB 1170 code in to separate subsystem. Kernel configs which include one of 1171 ums, ukbd, uhid, atp, wsp, wmt, uaudio, ugold or ucycom drivers should 1172 be updated with adding of "device hid" line. 1173 117420210105: 1175 ncurses installation has been modified to only keep the widechar 1176 enabled version. Incremental build is broken for that change, so it 1177 requires a clean build. 1178 117920201223: 1180 The FreeBSD project has migrated from Subversion to Git. Temporary 1181 instructions can be found at 1182 https://github.com/bsdimp/freebsd-git-docs/blob/main/src-cvt.md 1183 and other documents in that repo. 1184 118520201216: 1186 The services database has been updated to cover more of the basic 1187 services expected in a modern system. The database is big enough 1188 that it will cause issues in mergemaster in Releases previous to 1189 12.2 and 11.3, or in very old current systems from before r358154. 1190 119120201215: 1192 Obsolete in-tree GDB 6.1.1 has been removed. GDB (including kgdb) 1193 may be installed from ports or packages. 1194 119520201124: 1196 ping6 has been merged into ping. It can now be called as "ping -6". 1197 See ping(8) for details. 1198 119920201108: 1200 Default value of net.add_addr_allfibs has been changed to 0. 1201 If you have multi-fib configuration and rely on existence of all 1202 interface routes in every fib, you need to set the above sysctl to 1. 1203 120420201030: 1205 The internal pre-processor in the calendar(1) program has been 1206 extended to support more C pre-processor commands (e.g. #ifdef, #else, 1207 and #undef) and to detect unbalanced conditional statements. 1208 Error messages have been extended to include the filename and line 1209 number if processing stops to help fixing malformed data files. 1210 121120201026: 1212 All the data files for the calendar(1) program, except calendar.freebsd, 1213 have been moved to the deskutils/calendar-data port, much like the 1214 jewish calendar entries were moved to deskutils/hebcal years ago. After 1215 make delete-old-files, you need to install it to retain full 1216 functionality. calendar(1) will issue a reminder for files it can't 1217 find. 1218 121920200923: 1220 LINT files are no longer generated. We now include the relevant NOTES 1221 files. Note: This may cause conflicts with updating in some cases. 1222 find sys -name LINT\* -delete 1223 is suggested across this commit to remove the generated LINT files. 1224 1225 If you have tried to update with generated files there, the svn 1226 command you want to un-auger the tree is 1227 cd sys/amd64/conf 1228 svn revert -R . 1229 and then do the above find from the top level. Substitute 'amd64' 1230 above with where the error message indicates a conflict. 1231 123220200824: 1233 OpenZFS support has been integrated. Do not upgrade root pools until 1234 the loader is updated to support zstd. Furthermore, we caution against 1235 'zpool upgrade' for the next few weeks. The change should be transparent 1236 unless you want to use new features. 1237 1238 Not all "NO_CLEAN" build scenarios work across these changes. Many 1239 scenarios have been tested and fixed, but rebuilding kernels without 1240 rebuilding world may fail. 1241 1242 The ZFS cache file has moved from /boot to /etc to match the OpenZFS 1243 upstream default. A fallback to /boot has been added for mountroot. 1244 1245 Pool auto import behavior at boot has been moved from the kernel module 1246 to an explicit "zpool import -a" in one of the rc scripts enabled by 1247 zfs_enable=YES. This means your non-root zpools won't auto import until 1248 you upgrade your /etc/rc.d files. 1249 125020200824: 1251 The resume code now notifies devd with the 'kernel' system 1252 rather than the old 'kern' subsystem to be consistent with 1253 other use. The old notification will be created as well, but 1254 will be removed prior to FreeBSD 14.0. 1255 125620200821: 1257 r362275 changed the internal API between the kernel RPC and the 1258 NFS modules. As such, all the modules must be recompiled from 1259 sources. 1260 126120200817: 1262 r364330 modified the internal API used between the NFS modules. 1263 As such, all the NFS modules must be re-compiled from sources. 1264 126520200816: 1266 Clang, llvm, lld, lldb, compiler-rt, libc++, libunwind and openmp have 1267 been upgraded to 11.0.0. Please see the 20141231 entry below for 1268 information about prerequisites and upgrading, if you are not already 1269 using clang 3.5.0 or higher. 1270 127120200810: 1272 r364092 modified the internal ABI used between the kernel NFS 1273 modules. As such, all of these modules need to be rebuilt 1274 from sources, so a version bump was done. 1275 127620200807: 1277 Makefile.inc has been updated to work around the issue documented in 1278 20200729. It was a case where the optimization of using symbolic links 1279 to point to binaries created a situation where we'd run new binaries 1280 with old libraries starting midway through the installworld process. 1281 128220200729: 1283 r363679 has redefined some undefined behavior in regcomp(3); notably, 1284 extraneous escapes of most ordinary characters will no longer be 1285 accepted. An exp-run has identified all of the problems with this in 1286 ports, but other non-ports software may need extra escapes removed to 1287 continue to function. 1288 1289 Because of this change, installworld may encounter the following error 1290 from rtld: Undefined symbol "regcomp@FBSD_1.6" -- It is imperative that 1291 you do not halt installworld. Instead, let it run to completion (whether 1292 successful or not) and run installworld once more. 1293 129420200627: 1295 A new implementation of bc and dc has been imported in r362681. This 1296 implementation corrects non-conformant behavior of the previous bc 1297 and adds GNU bc compatible options. It offers a number of extensions, 1298 is much faster on large values, and has support for message catalogs 1299 (a number of languages are already supported, contributions of further 1300 languages welcome). The option WITHOUT_GH_BC can be used to build the 1301 world with the previous versions of bc and dc. 1302 130320200625: 1304 r362639 changed the internal API used between the NFS kernel modules. 1305 As such, they all need to be rebuilt from sources. 1306 130720200613: 1308 r362158 changed the arguments for VFS_CHECKEXP(). As such, any 1309 out of tree file systems need to be modified and rebuilt. 1310 Also, any file systems that are modules must be rebuilt. 1311 131220200604: 1313 read(2) of a directory fd is now rejected by default. root may 1314 re-enable it for system root only on non-ZFS filesystems with the 1315 security.bsd.allow_read_dir sysctl(8) MIB if 1316 security.bsd.suser_enabled=1. 1317 1318 It may be advised to setup aliases for grep to default to `-d skip` if 1319 commonly non-recursively grepping a list that includes directories and 1320 the potential for the resulting stderr output is not tolerable. Example 1321 aliases are now installed, commented out, in /root/.cshrc and 1322 /root/.shrc. 1323 132420200523: 1325 Clang, llvm, lld, lldb, compiler-rt, libc++, libunwind and openmp have 1326 been upgraded to 10.0.1. Please see the 20141231 entry below for 1327 information about prerequisites and upgrading, if you are not already 1328 using clang 3.5.0 or higher. 1329 133020200512: 1331 Support for obsolete compilers has been removed from the build system. 1332 Clang 6 and GCC 6.4 are the minimum supported versions. 1333 133420200424: 1335 closefrom(2) has been moved under COMPAT12, and replaced in libc with a 1336 stub that calls close_range(2). If using a custom kernel configuration, 1337 you may want to ensure that the COMPAT_FREEBSD12 option is included, as 1338 a slightly older -CURRENT userland and older FreeBSD userlands may not 1339 be functional without closefrom(2). 1340 134120200414: 1342 Upstream DTS from Linux 5.6 was merged and they now have the SID 1343 and THS (Secure ID controller and THermal Sensor) node present. 1344 The DTB overlays have now been removed from the tree for the H3/H5 and 1345 A64 SoCs and the aw_sid and aw_thermal driver have been updated to 1346 deal with upstream DTS. If you are using those overlays you need to 1347 remove them from loader.conf and update the DTBs on the FAT partition. 1348 134920200310: 1350 Clang, llvm, lld, lldb, compiler-rt, libc++, libunwind and openmp have 1351 been upgraded to 10.0.0. Please see the 20141231 entry below for 1352 information about prerequisites and upgrading, if you are not already 1353 using clang 3.5.0 or higher. 1354 135520200309: 1356 The amd(8) automount daemon has been removed from the source tree. 1357 As of FreeBSD 10.1 autofs(5) is the preferred tool for automounting. 1358 amd is still available in the sysutils/am-utils port. 1359 136020200301: 1361 Removed brooktree driver (bktr.4) from the tree. 1362 136320200229: 1364 The WITH_GPL_DTC option has been removed. The BSD-licenced device tree 1365 compiler in usr.bin/dtc is used on all architectures which use dtc, and 1366 the GPL dtc is available (if needed) from the sysutils/dtc port. 1367 136820200229: 1369 The WITHOUT_LLVM_LIBUNWIND option has been removed. LLVM's libunwind 1370 is used by all supported CPU architectures. 1371 137220200229: 1373 GCC 4.2.1 has been removed from the tree. The WITH_GCC, 1374 WITH_GCC_BOOTSTRAP, and WITH_GNUCXX options are no longer available. 1375 Users who wish to build FreeBSD with GCC must use the external toolchain 1376 ports or packages. 1377 137820200220: 1379 ncurses has been updated to a newer version (6.2-20200215). Given the ABI 1380 has changed, users will have to rebuild all the ports that are linked to 1381 ncurses. 1382 138320200217: 1384 The size of struct vnet and the magic cookie have changed. 1385 Users need to recompile libkvm and all modules using VIMAGE 1386 together with their new kernel. 1387 138820200212: 1389 Defining the long deprecated NO_CTF, NO_DEBUG_FILES, NO_INSTALLLIB, 1390 NO_MAN, NO_PROFILE, and NO_WARNS variables is now an error. Update 1391 your Makefiles and scripts to define MK_<var>=no instead as required. 1392 1393 One exception to this is that program or library Makefiles should 1394 define MAN to empty rather than setting MK_MAN=no. 1395 139620200108: 1397 Clang/LLVM is now the default compiler and LLD the default 1398 linker for riscv64. 1399 140020200107: 1401 make universe no longer uses GCC 4.2.1 on any architectures. 1402 Architectures not supported by in-tree Clang/LLVM require an 1403 external toolchain package. 1404 140520200104: 1406 GCC 4.2.1 is now not built by default, as part of the GCC 4.2.1 1407 retirement plan. Specifically, the GCC, GCC_BOOTSTRAP, and GNUCXX 1408 options default to off for all supported CPU architectures. As a 1409 short-term transition aid they may be enabled via WITH_* options. 1410 GCC 4.2.1 is expected to be removed from the tree on 2020-03-31. 1411 141220200102: 1413 Support for armv5 has been disconnected and is being removed. The 1414 machine combination MACHINE=arm MACHINE_ARCH=arm is no longer valid. 1415 You must now use a MACHINE_ARCH of armv6 or armv7. The default 1416 MACHINE_ARCH for MACHINE=arm is now armv7. 1417 141820191226: 1419 Clang/LLVM is now the default compiler for all powerpc architectures. 1420 LLD is now the default linker for powerpc64. The change for powerpc64 1421 also includes a change to the ELFv2 ABI, incompatible with the existing 1422 ABI. 1423 142420191226: 1425 Kernel-loadable random(4) modules are no longer unloadable. 1426 142720191222: 1428 Clang, llvm, lld, lldb, compiler-rt, libc++, libunwind and openmp have 1429 been upgraded to 9.0.1. Please see the 20141231 entry below for 1430 information about prerequisites and upgrading, if you are not already 1431 using clang 3.5.0 or higher. 1432 143320191212: 1434 r355677 has modified the internal interface used between the 1435 NFS modules in the kernel. As such, they must all be upgraded 1436 simultaneously. I will do a version bump for this. 1437 143820191205: 1439 The root certificates of the Mozilla CA Certificate Store have been 1440 imported into the base system and can be managed with the certctl(8) 1441 utility. If you have installed the security/ca_root_nss port or package 1442 with the ETCSYMLINK option (the default), be advised that there may be 1443 differences between those included in the port and those included in 1444 base due to differences in nss branch used as well as general update 1445 frequency. Note also that certctl(8) cannot manage certs in the 1446 format used by the security/ca_root_nss port. 1447 144820191120: 1449 The amd(8) automount daemon has been disabled by default, and will be 1450 removed in the future. As of FreeBSD 10.1 the autofs(5) is available 1451 for automounting. 1452 145320191107: 1454 The nctgpio and wbwd drivers have been moved to the superio bus. 1455 If you have one of these drivers in a kernel configuration, then 1456 you should add device superio to it. If you use one of these drivers 1457 as a module and you compile a custom set of modules, then you should 1458 add superio to the set. 1459 146020191021: 1461 KPIs for network drivers to access interface addresses have changed. 1462 Users need to recompile NIC driver modules together with kernel. 1463 146420191021: 1465 The net.link.tap.user_open sysctl no longer prevents user opening of 1466 already created /dev/tapNN devices. Access is still controlled by 1467 node permissions, just like tun devices. The net.link.tap.user_open 1468 sysctl is now used only to allow users to perform devfs cloning of 1469 tap devices, and the subsequent open may not succeed if the user is not 1470 in the appropriate group. This sysctl may be deprecated/removed 1471 completely in the future. 1472 147320191009: 1474 mips, powerpc, and sparc64 are no longer built as part of 1475 universe / tinderbox unless MAKE_OBSOLETE_GCC is defined. If 1476 not defined, mips, powerpc, and sparc64 builds will look for 1477 the xtoolchain binaries and if installed use them for universe 1478 builds. As llvm 9.0 becomes vetted for these architectures, they 1479 will be removed from the list. 1480 148120191009: 1482 Clang, llvm, lld, lldb, compiler-rt, libc++, libunwind and openmp have 1483 been upgraded to 9.0.0. Please see the 20141231 entry below for 1484 information about prerequisites and upgrading, if you are not already 1485 using clang 3.5.0 or higher. 1486 148720191003: 1488 The hpt27xx, hptmv, hptnr, and hptrr drivers have been removed from 1489 GENERIC. They are available as modules and can be loaded by adding 1490 to /boot/loader.conf hpt27xx_load="YES", hptmv_load="YES", 1491 hptnr_load="YES", or hptrr_load="YES", respectively. 1492 149320190913: 1494 ntpd no longer by default locks its pages in memory, allowing them 1495 to be paged out by the kernel. Use rlimit memlock to restore 1496 historic BSD behaviour. For example, add "rlimit memlock 32" 1497 to ntp.conf to lock up to 32 MB of ntpd address space in memory. 1498 149920190823: 1500 Several of ping6's options have been renamed for better consistency 1501 with ping. If you use any of -ARWXaghmrtwx, you must update your 1502 scripts. See ping6(8) for details. 1503 150420190727: 1505 The vfs.fusefs.sync_unmount and vfs.fusefs.init_backgrounded sysctls 1506 and the "-o sync_unmount" and "-o init_backgrounded" mount options have 1507 been removed from mount_fusefs(8). You can safely remove them from 1508 your scripts, because they had no effect. 1509 1510 The vfs.fusefs.fix_broken_io, vfs.fusefs.sync_resize, 1511 vfs.fusefs.refresh_size, vfs.fusefs.mmap_enable, 1512 vfs.fusefs.reclaim_revoked, and vfs.fusefs.data_cache_invalidate 1513 sysctls have been removed. If you felt the need to set any of them to 1514 a non-default value, please tell asomers@FreeBSD.org why. 1515 151620190713: 1517 Default permissions on the /var/account/acct file (and copies of it 1518 rotated by periodic daily scripts) are changed from 0644 to 0640 1519 because the file contains sensitive information that should not be 1520 world-readable. If the /var/account directory must be created by 1521 rc.d/accounting, the mode used is now 0750. Admins who use the 1522 accounting feature are encouraged to change the mode of an existing 1523 /var/account directory to 0750 or 0700. 1524 152520190620: 1526 Entropy collection and the /dev/random device are no longer optional 1527 components. The "device random" option has been removed. 1528 Implementations of distilling algorithms can still be made loadable 1529 with "options RANDOM_LOADABLE" (e.g., random_fortuna.ko). 1530 153120190612: 1532 Clang, llvm, lld, lldb, compiler-rt, libc++, libunwind and openmp have 1533 been upgraded to 8.0.1. Please see the 20141231 entry below for 1534 information about prerequisites and upgrading, if you are not already 1535 using clang 3.5.0 or higher. 1536 153720190608: 1538 A fix was applied to i386 kernel modules to avoid panics with 1539 dpcpu or vnet. Users need to recompile i386 kernel modules 1540 having pcpu or vnet sections or they will refuse to load. 1541 154220190513: 1543 User-wired pages now have their own counter, 1544 vm.stats.vm.v_user_wire_count. The vm.max_wired sysctl was renamed 1545 to vm.max_user_wired and changed from an unsigned int to an unsigned 1546 long. bhyve VMs wired with the -S are now subject to the user 1547 wiring limit; the vm.max_user_wired sysctl may need to be tuned to 1548 avoid running into the limit. 1549 155020190507: 1551 The IPSEC option has been removed from GENERIC. Users requiring 1552 ipsec(4) must now load the ipsec(4) kernel module. 1553 155420190507: 1555 The tap(4) driver has been folded into tun(4), and the module has been 1556 renamed to tuntap. You should update any kld_list="if_tap" or 1557 kld_list="if_tun" entries in /etc/rc.conf, if_tap_load="YES" or 1558 if_tun_load="YES" entries in /boot/loader.conf to load the if_tuntap 1559 module instead, and "device tap" or "device tun" entries in kernel 1560 config files to select the tuntap device instead. 1561 156220190418: 1563 The following knobs have been added related to tradeoffs between 1564 safe use of the random device and availability in the absence of 1565 entropy: 1566 1567 kern.random.initial_seeding.bypass_before_seeding: tunable; set 1568 non-zero to bypass the random device prior to seeding, or zero to 1569 block random requests until the random device is initially seeded. 1570 For now, set to 1 (unsafe) by default to restore pre-r346250 boot 1571 availability properties. 1572 1573 kern.random.initial_seeding.read_random_bypassed_before_seeding: 1574 read-only diagnostic sysctl that is set when bypass is enabled and 1575 read_random(9) is bypassed, to enable programmatic handling of this 1576 initial condition, if desired. 1577 1578 kern.random.initial_seeding.arc4random_bypassed_before_seeding: 1579 Similar to the above, but for arc4random(9) initial seeding. 1580 1581 kern.random.initial_seeding.disable_bypass_warnings: tunable; set 1582 non-zero to disable warnings in dmesg when the same conditions are 1583 met as for the diagnostic sysctls above. Defaults to zero, i.e., 1584 produce warnings in dmesg when the conditions are met. 1585 158620190416: 1587 The loadable random module KPI has changed; the random_infra_init() 1588 routine now requires a 3rd function pointer for a bool (*)(void) 1589 method that returns true if the random device is seeded (and 1590 therefore unblocked). 1591 159220190404: 1593 r345895 reverts r320698. This implies that an nfsuserd(8) daemon 1594 built from head sources between r320757 (July 6, 2017) and 1595 r338192 (Aug. 22, 2018) will not work unless the "-use-udpsock" 1596 is added to the command line. 1597 nfsuserd daemons built from head sources that are post-r338192 are 1598 not affected and should continue to work. 1599 160020190320: 1601 The fuse(4) module has been renamed to fusefs(4) for consistency with 1602 other filesystems. You should update any kld_load="fuse" entries in 1603 /etc/rc.conf, fuse_load="YES" entries in /boot/loader.conf, and 1604 "options FUSE" entries in kernel config files. 1605 160620190304: 1607 Clang, llvm, lld, lldb, compiler-rt and libc++ have been upgraded to 1608 8.0.0. Please see the 20141231 entry below for information about 1609 prerequisites and upgrading, if you are not already using clang 3.5.0 1610 or higher. 1611 161220190226: 1613 geom_uzip(4) depends on the new module xz. If geom_uzip is statically 1614 compiled into your custom kernel, add 'device xz' statement to the 1615 kernel config. 1616 161720190219: 1618 drm and drm2 have been removed from the tree. Please see 1619 https://wiki.freebsd.org/Graphics for the latest information on 1620 migrating to the drm ports. 1621 162220190131: 1623 Iflib is no longer unconditionally compiled into the kernel. Drivers 1624 using iflib and statically compiled into the kernel, now require 1625 the 'device iflib' config option. For the same drivers loaded as 1626 modules on kernels not having 'device iflib', the iflib.ko module 1627 is loaded automatically. 1628 162920190125: 1630 The IEEE80211_AMPDU_AGE and AH_SUPPORT_AR5416 kernel configuration 1631 options no longer exist since r343219 and r343427 respectively; 1632 nothing uses them, so they should be just removed from custom 1633 kernel config files. 1634 163520181230: 1636 r342635 changes the way efibootmgr(8) works by requiring users to add 1637 the -b (bootnum) parameter for commands where the bootnum was previously 1638 specified with each option. For example 'efibootmgr -B 0001' is now 1639 'efibootmgr -B -b 0001'. 1640 164120181220: 1642 r342286 modifies the NFSv4 server so that it obeys vfs.nfsd.nfs_privport 1643 in the same as it is applied to NFSv2 and 3. This implies that NFSv4 1644 servers that have vfs.nfsd.nfs_privport set will only allow mounts 1645 from clients using a reserved port. Since both the FreeBSD and Linux 1646 NFSv4 clients use reserved ports by default, this should not affect 1647 most NFSv4 mounts. 1648 164920181219: 1650 The XLP config has been removed. We can't support 64-bit atomics in this 1651 kernel because it is running in 32-bit mode. XLP users must transition 1652 to running a 64-bit kernel (XLP64 or XLPN32). 1653 1654 The mips GXEMUL support has been removed from FreeBSD. MALTA* + qemu is 1655 the preferred emulator today and we don't need two different ones. 1656 1657 The old sibyte / swarm / Broadcom BCM1250 support has been 1658 removed from the mips port. 1659 166020181211: 1661 Clang, llvm, lld, lldb, compiler-rt and libc++ have been upgraded to 1662 7.0.1. Please see the 20141231 entry below for information about 1663 prerequisites and upgrading, if you are not already using clang 3.5.0 1664 or higher. 1665 166620181211: 1667 Remove the timed and netdate programs from the base tree. Setting 1668 the time with these daemons has been obsolete for over a decade. 1669 167020181126: 1671 On amd64, arm64 and armv7 (architectures that install LLVM's ld.lld 1672 linker as /usr/bin/ld) GNU ld is no longer installed as ld.bfd, as 1673 it produces broken binaries when ifuncs are in use. Users needing 1674 GNU ld should install the binutils port or package. 1675 167620181123: 1677 The BSD crtbegin and crtend code has been enabled by default. It has 1678 had extensive testing on amd64, arm64, and i386. It can be disabled 1679 by building a world with -DWITHOUT_BSD_CRTBEGIN. 1680 168120181115: 1682 The set of CTM commands (ctm, ctm_smail, ctm_rmail, ctm_dequeue) 1683 has been converted to a port (misc/ctm) and will be removed from 1684 FreeBSD-13. It is available as a package (ctm) for all supported 1685 FreeBSD versions. 1686 168720181110: 1688 The default newsyslog.conf(5) file has been changed to only include 1689 files in /etc/newsyslog.conf.d/ and /usr/local/etc/newsyslog.conf.d/ if 1690 the filenames end in '.conf' and do not begin with a '.'. 1691 1692 You should check the configuration files in these two directories match 1693 this naming convention. You can verify which configuration files are 1694 being included using the command: 1695 $ newsyslog -Nrv 1696 169720181019: 1698 Stable/12 was branched created. 1699 170020181015: 1701 Ports for the DRM modules have been simplified. Now, amd64 users should 1702 just install the drm-kmod port. All others should install 1703 drm-legacy-kmod. 1704 1705 Graphics hardware that's newer than about 2010 usually works with 1706 drm-kmod. For hardware older than 2013, however, some users will need 1707 to use drm-legacy-kmod if drm-kmod doesn't work for them. Hardware older 1708 than 2008 usually only works in drm-legacy-kmod. The graphics team can 1709 only commit to hardware made since 2013 due to the complexity of the 1710 market and difficulty to test all the older cards effectively. If you 1711 have hardware supported by drm-kmod, you are strongly encouraged to use 1712 that as you will get better support. 1713 1714 Other than KPI chasing, drm-legacy-kmod will not be updated. As outlined 1715 elsewhere, the drm and drm2 modules will be eliminated from the src base 1716 soon (with a limited exception for arm). Please update to the package 1717 asap and report any issues to x11@freebsd.org. 1718 1719 Generally, anybody using the drm*-kmod packages should add 1720 WITHOUT_DRM_MODULE=t and WITHOUT_DRM2_MODULE=t to avoid nasty 1721 cross-threading surprises, especially with automatic driver 1722 loading from X11 startup. These will become the defaults in 13-current 1723 shortly. 1724 172520181012: 1726 The ixlv(4) driver has been renamed to iavf(4). As a consequence, 1727 custom kernel and module loading configuration files must be updated 1728 accordingly. Moreover, interfaces previous presented as ixlvN to the 1729 system are now exposed as iavfN and network configuration files must 1730 be adjusted as necessary. 1731 173220181009: 1733 OpenSSL has been updated to version 1.1.1. This update included 1734 additional various API changes throughout the base system. It is 1735 important to rebuild third-party software after upgrading. The value 1736 of __FreeBSD_version has been bumped accordingly. 1737 173820181006: 1739 The legacy DRM modules and drivers have now been added to the loader's 1740 module blacklist, in favor of loading them with kld_list in rc.conf(5). 1741 The module blacklist may be overridden with the loader.conf(5) 1742 'module_blacklist' variable, but loading them via rc.conf(5) is strongly 1743 encouraged. 1744 174520181002: 1746 The cam(4) based nda(4) driver will be used over nvd(4) by default on 1747 powerpc64. You may set 'options NVME_USE_NVD=1' in your kernel conf or 1748 loader tunable 'hw.nvme.use_nvd=1' if you wish to use the existing 1749 driver. Make sure to edit /boot/etc/kboot.conf and fstab to use the 1750 nda device name. 1751 175220180913: 1753 Reproducible build mode is now on by default, in preparation for 1754 FreeBSD 12.0. This eliminates build metadata such as the user, 1755 host, and time from the kernel (and uname), unless the working tree 1756 corresponds to a modified checkout from a version control system. 1757 The previous behavior can be obtained by setting the /etc/src.conf 1758 knob WITHOUT_REPRODUCIBLE_BUILD. 1759 176020180826: 1761 The Yarrow CSPRNG has been removed from the kernel as it has not been 1762 supported by its designers since at least 2003. Fortuna has been the 1763 default since FreeBSD-11. 1764 176520180822: 1766 devctl freeze/thaw have gone into the tree, the rc scripts have been 1767 updated to use them and devmatch has been changed. You should update 1768 kernel, userland and rc scripts all at the same time. 1769 177020180818: 1771 The default interpreter has been switched from 4th to Lua. 1772 LOADER_DEFAULT_INTERP, documented in build(7), will override the default 1773 interpreter. If you have custom FORTH code you will need to set 1774 LOADER_DEFAULT_INTERP=4th (valid values are 4th, lua or simp) in 1775 src.conf for the build. This will create default hard links between 1776 loader and loader_4th instead of loader and loader_lua, the new default. 1777 If you are using UEFI it will create the proper hard link to loader.efi. 1778 1779 bhyve uses userboot.so. It remains 4th-only until some issues are solved 1780 regarding coexisting with multiple versions of FreeBSD are resolved. 1781 178220180815: 1783 ls(1) now respects the COLORTERM environment variable used in other 1784 systems and software to indicate that a colored terminal is both 1785 supported and desired. If ls(1) is suddenly emitting colors, they may 1786 be disabled again by either removing the unwanted COLORTERM from your 1787 environment, or using `ls --color=never`. The ls(1) specific CLICOLOR 1788 may not be observed in a future release. 1789 179020180808: 1791 The default pager for most commands has been changed to "less". To 1792 restore the old behavior, set PAGER="more" and MANPAGER="more -s" in 1793 your environment. 1794 179520180731: 1796 The jedec_ts(4) driver has been removed. A superset of its functionality 1797 is available in the jedec_dimm(4) driver, and the manpage for that 1798 driver includes migration instructions. If you have "device jedec_ts" 1799 in your kernel configuration file, it must be removed. 1800 180120180730: 1802 amd64/GENERIC now has EFI runtime services, EFIRT, enabled by default. 1803 This should have no effect if the kernel is booted via BIOS/legacy boot. 1804 EFIRT may be disabled via a loader tunable, efi.rt.disabled, if a system 1805 has a buggy firmware that prevents a successful boot due to use of 1806 runtime services. 1807 180820180727: 1809 Atmel AT91RM9200 and AT91SAM9, Cavium CNS 11xx and XScale 1810 support has been removed from the tree. These ports were 1811 obsolete and/or known to be broken for many years. 1812 181320180723: 1814 loader.efi has been augmented to participate more fully in the 1815 UEFI boot manager protocol. loader.efi will now look at the 1816 BootXXXX environment variable to determine if a specific kernel 1817 or root partition was specified. XXXX is derived from BootCurrent. 1818 efibootmgr(8) manages these standard UEFI variables. 1819 182020180720: 1821 zfsloader's functionality has now been folded into loader. 1822 zfsloader is no longer necessary once you've updated your 1823 boot blocks. For a transition period, we will install a 1824 hardlink for zfsloader to loader to allow a smooth transition 1825 until the boot blocks can be updated (hard link because old 1826 zfs boot blocks don't understand symlinks). 1827 182820180719: 1829 ARM64 now have efifb support, if you want to have serial console 1830 on your arm64 board when an screen is connected and the bootloader 1831 setup a frame buffer for us to use, just add : 1832 boot_serial=YES 1833 boot_multicons=YES 1834 in /boot/loader.conf 1835 For Raspberry Pi 3 (RPI) users, this is needed even if you don't have 1836 an screen connected as the firmware will setup a frame buffer are that 1837 u-boot will expose as an EFI frame buffer. 1838 183920180719: 1840 New uid:gid added, ntpd:ntpd (123:123). Be sure to run mergemaster 1841 or take steps to update /etc/passwd before doing installworld on 1842 existing systems. Do not skip the "mergemaster -Fp" step before 1843 installworld, as described in the update procedures near the bottom 1844 of this document. Also, rc.d/ntpd now starts ntpd(8) as user ntpd 1845 if the new mac_ntpd(4) policy is available, unless ntpd_flags or 1846 the ntp config file contain options that change file/dir locations. 1847 When such options (e.g., "statsdir" or "crypto") are used, ntpd can 1848 still be run as non-root by setting ntpd_user=ntpd in rc.conf, after 1849 taking steps to ensure that all required files/dirs are accessible 1850 by the ntpd user. 1851 185220180717: 1853 Big endian arm support has been removed. 1854 185520180711: 1856 The static environment setup in kernel configs is no longer mutually 1857 exclusive with the loader(8) environment by default. In order to 1858 restore the previous default behavior of disabling the loader(8) 1859 environment if a static environment is present, you must specify 1860 loader_env.disabled=1 in the static environment. 1861 186220180705: 1863 The ABI of syscalls used by management tools like sockstat and 1864 netstat has been broken to allow 32-bit binaries to work on 1865 64-bit kernels without modification. These programs will need 1866 to match the kernel in order to function. External programs may 1867 require minor modifications to accommodate a change of type in 1868 structures from pointers to 64-bit virtual addresses. 1869 187020180702: 1871 On i386 and amd64 atomics are now inlined. Out of tree modules using 1872 atomics will need to be rebuilt. 1873 187420180701: 1875 The '%I' format in the kern.corefile sysctl limits the number of 1876 core files that a process can generate to the number stored in the 1877 debug.ncores sysctl. The '%I' format is replaced by the single digit 1878 index. Previously, if all indexes were taken the kernel would overwrite 1879 only a core file with the highest index in a filename. 1880 Currently the system will create a new core file if there is a free 1881 index or if all slots are taken it will overwrite the oldest one. 1882 188320180630: 1884 Clang, llvm, lld, lldb, compiler-rt and libc++ have been upgraded to 1885 6.0.1. Please see the 20141231 entry below for information about 1886 prerequisites and upgrading, if you are not already using clang 3.5.0 1887 or higher. 1888 188920180628: 1890 r335753 introduced a new quoting method. However, etc/devd/devmatch.conf 1891 needed to be changed to work with it. This change was made with r335763 1892 and requires a mergemaster / etcupdate / etc to update the installed 1893 file. 1894 189520180612: 1896 r334930 changed the interface between the NFS modules, so they all 1897 need to be rebuilt. r335018 did a __FreeBSD_version bump for this. 1898 189920180530: 1900 As of r334391 lld is the default amd64 system linker; it is installed 1901 as /usr/bin/ld. Kernel build workarounds (see 20180510 entry) are no 1902 longer necessary. 1903 190420180530: 1905 The kernel / userland interface for devinfo changed, so you'll 1906 need a new kernel and userland as a pair for it to work (rebuilding 1907 lib/libdevinfo is all that's required). devinfo and devmatch will 1908 not work, but everything else will when there's a mismatch. 1909 191020180523: 1911 The on-disk format for hwpmc callchain records has changed to include 1912 threadid corresponding to a given record. This changes the field offsets 1913 and thus requires that libpmcstat be rebuilt before using a kernel 1914 later than r334108. 1915 191620180517: 1917 The vxge(4) driver has been removed. This driver was introduced into 1918 HEAD one week before the Exar left the Ethernet market and is not 1919 known to be used. If you have device vxge in your kernel config file 1920 it must be removed. 1921 192220180510: 1923 The amd64 kernel now requires a ld that supports ifunc to produce a 1924 working kernel, either lld or a newer binutils. lld is built by default 1925 on amd64, and the 'buildkernel' target uses it automatically. However, 1926 it is not the default linker, so building the kernel the traditional 1927 way requires LD=ld.lld on the command line (or LD=/usr/local/bin/ld for 1928 binutils port/package). lld will soon be default, and this requirement 1929 will go away. 1930 1931 NOTE: As of r334391 lld is the default system linker on amd64, and no 1932 workaround is necessary. 1933 193420180508: 1935 The nxge(4) driver has been removed. This driver was for PCI-X 10g 1936 cards made by s2io/Neterion. The company was acquired by Exar and 1937 no longer sells or supports Ethernet products. If you have device 1938 nxge in your kernel config file it must be removed. 1939 194020180504: 1941 The tz database (tzdb) has been updated to 2018e. This version more 1942 correctly models time stamps in time zones with negative DST such as 1943 Europe/Dublin (from 1971 on), Europe/Prague (1946/7), and 1944 Africa/Windhoek (1994/2017). This does not affect the UT offsets, only 1945 time zone abbreviations and the tm_isdst flag. 1946 194720180502: 1948 The ixgb(4) driver has been removed. This driver was for an early and 1949 uncommon legacy PCI 10GbE for a single ASIC, Intel 82597EX. Intel 1950 quickly shifted to the long lived ixgbe family. If you have device 1951 ixgb in your kernel config file it must be removed. 1952 195320180501: 1954 The lmc(4) driver has been removed. This was a WAN interface 1955 card that was already reportedly rare in 2003, and had an ambiguous 1956 license. If you have device lmc in your kernel config file it must 1957 be removed. 1958 195920180413: 1960 Support for Arcnet networks has been removed. If you have device 1961 arcnet or device cm in your kernel config file they must be 1962 removed. 1963 196420180411: 1965 Support for FDDI networks has been removed. If you have device 1966 fddi or device fpa in your kernel config file they must be 1967 removed. 1968 196920180406: 1970 In addition to supporting RFC 3164 formatted messages, the 1971 syslogd(8) service is now capable of parsing RFC 5424 formatted 1972 log messages. The main benefit of using RFC 5424 is that clients 1973 may now send log messages with timestamps containing year numbers, 1974 microseconds and time zone offsets. 1975 1976 Similarly, the syslog(3) C library function has been altered to 1977 send RFC 5424 formatted messages to the local system logging 1978 daemon. On systems using syslogd(8), this change should have no 1979 negative impact, as long as syslogd(8) and the C library are 1980 updated at the same time. On systems using a different system 1981 logging daemon, it may be necessary to make configuration 1982 adjustments, depending on the software used. 1983 1984 When using syslog-ng, add the 'syslog-protocol' flag to local 1985 input sources to enable parsing of RFC 5424 formatted messages: 1986 1987 source src { 1988 unix-dgram("/var/run/log" flags(syslog-protocol)); 1989 } 1990 1991 When using rsyslog, disable the 'SysSock.UseSpecialParser' option 1992 of the 'imuxsock' module to let messages be processed by the 1993 regular RFC 3164/5424 parsing pipeline: 1994 1995 module(load="imuxsock" SysSock.UseSpecialParser="off") 1996 1997 Do note that these changes only affect communication between local 1998 applications and syslogd(8). The format that syslogd(8) uses to 1999 store messages on disk or forward messages to other systems 2000 remains unchanged. syslogd(8) still uses RFC 3164 for these 2001 purposes. Options to customize this behaviour will be added in the 2002 future. Utilities that process log files stored in /var/log are 2003 thus expected to continue to function as before. 2004 2005 __FreeBSD_version has been incremented to 1200061 to denote this 2006 change. 2007 200820180328: 2009 Support for token ring networks has been removed. If you 2010 have "device token" in your kernel config you should remove 2011 it. No device drivers supported token ring. 2012 201320180323: 2014 makefs was modified to be able to tag ISO9660 El Torito boot catalog 2015 entries as EFI instead of overloading the i386 tag as done previously. 2016 The amd64 mkisoimages.sh script used to build amd64 ISO images for 2017 release was updated to use this. This may mean that makefs must be 2018 updated before "make cdrom" can be run in the release directory. This 2019 should be as simple as: 2020 2021 $ cd $SRCDIR/usr.sbin/makefs 2022 $ make depend all install 2023 202420180212: 2025 FreeBSD boot loader enhanced with Lua scripting. It's purely opt-in for 2026 now by building WITH_LOADER_LUA and WITHOUT_FORTH in /etc/src.conf. 2027 Co-existence for the transition period will come shortly. Booting is a 2028 complex environment and test coverage for Lua-enabled loaders has been 2029 thin, so it would be prudent to assume it might not work and make 2030 provisions for backup boot methods. 2031 203220180211: 2033 devmatch functionality has been turned on in devd. It will automatically 2034 load drivers for unattached devices. This may cause unexpected drivers 2035 to be loaded. Please report any problems to current@ and 2036 imp@freebsd.org. 2037 203820180114: 2039 Clang, llvm, lld, lldb, compiler-rt and libc++ have been upgraded to 2040 6.0.0. Please see the 20141231 entry below for information about 2041 prerequisites and upgrading, if you are not already using clang 3.5.0 2042 or higher. 2043 204420180110: 2045 LLVM's lld linker is now used as the FreeBSD/amd64 bootstrap linker. 2046 This means it is used to link the kernel and userland libraries and 2047 executables, but is not yet installed as /usr/bin/ld by default. 2048 2049 To revert to ld.bfd as the bootstrap linker, in /etc/src.conf set 2050 WITHOUT_LLD_BOOTSTRAP=yes 2051 205220180110: 2053 On i386, pmtimer has been removed. Its functionality has been folded 2054 into apm. It was a no-op on ACPI in current for a while now (but was 2055 still needed on i386 in FreeBSD 11 and earlier). Users may need to 2056 remove it from kernel config files. 2057 205820180104: 2059 The use of RSS hash from the network card aka flowid has been 2060 disabled by default for lagg(4) as it's currently incompatible with 2061 the lacp and loadbalance protocols. 2062 2063 This can be re-enabled by setting the following in loader.conf: 2064 net.link.lagg.default_use_flowid="1" 2065 206620180102: 2067 The SW_WATCHDOG option is no longer necessary to enable the 2068 hardclock-based software watchdog if no hardware watchdog is 2069 configured. As before, SW_WATCHDOG will cause the software 2070 watchdog to be enabled even if a hardware watchdog is configured. 2071 207220171215: 2073 r326887 fixes the issue described in the 20171214 UPDATING entry. 2074 r326888 flips the switch back to building GELI support always. 2075 207620171214: 2077 r362593 broke ZFS + GELI support for reasons unknown. However, 2078 it also broke ZFS support generally, so GELI has been turned off 2079 by default as the lesser evil in r326857. If you boot off ZFS and/or 2080 GELI, it might not be a good time to update. 2081 208220171125: 2083 PowerPC users must update loader(8) by rebuilding world before 2084 installing a new kernel, as the protocol connecting them has 2085 changed. Without the update, loader metadata will not be passed 2086 successfully to the kernel and users will have to enter their 2087 root partition at the kernel mountroot prompt to continue booting. 2088 Newer versions of loader can boot old kernels without issue. 2089 209020171110: 2091 The LOADER_FIREWIRE_SUPPORT build variable has been renamed to 2092 WITH/OUT_LOADER_FIREWIRE. LOADER_{NO_,}GELI_SUPPORT has been renamed 2093 to WITH/OUT_LOADER_GELI. 2094 209520171106: 2096 The naive and non-compliant support of posix_fallocate(2) in ZFS 2097 has been removed as of r325320. The system call now returns EINVAL 2098 when used on a ZFS file. Although the new behavior complies with the 2099 standard, some consumers are not prepared to cope with it. 2100 One known victim is lld prior to r325420. 2101 210220171102: 2103 Building in a FreeBSD src checkout will automatically create object 2104 directories now rather than store files in the current directory if 2105 'make obj' was not ran. Calling 'make obj' is no longer necessary. 2106 This feature can be disabled by setting WITHOUT_AUTO_OBJ=yes in 2107 /etc/src-env.conf (not /etc/src.conf), or passing the option in the 2108 environment. 2109 211020171101: 2111 The default MAKEOBJDIR has changed from /usr/obj/<srcdir> for native 2112 builds, and /usr/obj/<arch>/<srcdir> for cross-builds, to a unified 2113 /usr/obj/<srcdir>/<arch>. This behavior can be changed to the old 2114 format by setting WITHOUT_UNIFIED_OBJDIR=yes in /etc/src-env.conf, 2115 the environment, or with -DWITHOUT_UNIFIED_OBJDIR when building. 2116 The UNIFIED_OBJDIR option is a transitional feature that will be 2117 removed for 12.0 release; please migrate to the new format for any 2118 tools by looking up the OBJDIR used by 'make -V .OBJDIR' means rather 2119 than hardcoding paths. 2120 212120171028: 2122 The native-xtools target no longer installs the files by default to the 2123 OBJDIR. Use the native-xtools-install target with a DESTDIR to install 2124 to ${DESTDIR}/${NXTP} where NXTP defaults to /nxb-bin. 2125 212620171021: 2127 As part of the boot loader infrastructure cleanup, LOADER_*_SUPPORT 2128 options are changing from controlling the build if defined / undefined 2129 to controlling the build with explicit 'yes' or 'no' values. They will 2130 shift to WITH/WITHOUT options to match other options in the system. 2131 213220171010: 2133 libstand has turned into a private library for sys/boot use only. 2134 It is no longer supported as a public interface outside of sys/boot. 2135 213620171005: 2137 The arm port has split armv6 into armv6 and armv7. armv7 is now 2138 a valid TARGET_ARCH/MACHINE_ARCH setting. If you have an armv7 system 2139 and are running a kernel from before r324363, you will need to add 2140 MACHINE_ARCH=armv7 to 'make buildworld' to do a native build. 2141 214220171003: 2143 When building multiple kernels using KERNCONF, non-existent KERNCONF 2144 files will produce an error and buildkernel will fail. Previously 2145 missing KERNCONF files silently failed giving no indication as to 2146 why, only to subsequently discover during installkernel that the 2147 desired kernel was never built in the first place. 2148 214920170912: 2150 The default serial number format for CTL LUNs has changed. This will 2151 affect users who use /dev/diskid/* device nodes, or whose FibreChannel 2152 or iSCSI clients care about their LUNs' serial numbers. Users who 2153 require serial number stability should hardcode serial numbers in 2154 /etc/ctl.conf . 2155 215620170912: 2157 For 32-bit arm compiled for hard-float support, soft-floating point 2158 binaries now always get their shared libraries from 2159 LD_SOFT_LIBRARY_PATH (in the past, this was only used if 2160 /usr/libsoft also existed). Only users with a hard-float ld.so, but 2161 soft-float everything else should be affected. 2162 216320170826: 2164 The geli password typed at boot is now hidden. To restore the previous 2165 behavior, see geli(8) for configuration options. 2166 216720170825: 2168 Move PMTUD blackhole counters to TCPSTATS and remove them from bare 2169 sysctl values. Minor nit, but requires a rebuild of both world/kernel 2170 to complete. 2171 217220170814: 2173 "make check" behavior (made in ^/head@r295380) has been changed to 2174 execute from a limited sandbox, as opposed to executing from 2175 ${TESTSDIR}. 2176 2177 Behavioral changes: 2178 - The "beforecheck" and "aftercheck" targets are now specified. 2179 - ${CHECKDIR} (added in commit noted above) has been removed. 2180 - Legacy behavior can be enabled by setting 2181 WITHOUT_MAKE_CHECK_USE_SANDBOX in src.conf(5) or the environment. 2182 2183 If the limited sandbox mode is enabled, "make check" will execute 2184 "make distribution", then install, execute the tests, and clean up the 2185 sandbox if successful. 2186 2187 The "make distribution" and "make install" targets are typically run as 2188 root to set appropriate permissions and ownership at installation time. 2189 The end-user should set "WITH_INSTALL_AS_USER" in src.conf(5) or the 2190 environment if executing "make check" with limited sandbox mode using 2191 an unprivileged user. 2192 219320170808: 2194 Since the switch to GPT disk labels, fsck for UFS/FFS has been 2195 unable to automatically find alternate superblocks. As of r322297, 2196 the information needed to find alternate superblocks has been 2197 moved to the end of the area reserved for the boot block. 2198 Filesystems created with a newfs of this vintage or later 2199 will create the recovery information. If you have a filesystem 2200 created prior to this change and wish to have a recovery block 2201 created for your filesystem, you can do so by running fsck in 2202 foreground mode (i.e., do not use the -p or -y options). As it 2203 starts, fsck will ask ``SAVE DATA TO FIND ALTERNATE SUPERBLOCKS'' 2204 to which you should answer yes. 2205 220620170728: 2207 As of r321665, an NFSv4 server configuration that services 2208 Kerberos mounts or clients that do not support the uid/gid in 2209 owner/owner_group string capability, must explicitly enable 2210 the nfsuserd daemon by adding nfsuserd_enable="YES" to the 2211 machine's /etc/rc.conf file. 2212 221320170722: 2214 Clang, llvm, lldb, compiler-rt and libc++ have been upgraded to 5.0.0. 2215 Please see the 20141231 entry below for information about prerequisites 2216 and upgrading, if you are not already using clang 3.5.0 or higher. 2217 221820170701: 2219 WITHOUT_RCMDS is now the default. Set WITH_RCMDS if you need the 2220 r-commands (rlogin, rsh, etc.) to be built with the base system. 2221 222220170625: 2223 The FreeBSD/powerpc platform now uses a 64-bit type for time_t. This is 2224 a very major ABI incompatible change, so users of FreeBSD/powerpc must 2225 be careful when performing source upgrades. It is best to run 2226 'make installworld' from an alternate root system, either a live 2227 CD/memory stick, or a temporary root partition. Additionally, all ports 2228 must be recompiled. powerpc64 is largely unaffected, except in the case 2229 of 32-bit compatibility. All 32-bit binaries will be affected. 2230 223120170623: 2232 Forward compatibility for the "ino64" project have been committed. This 2233 will allow most new binaries to run on older kernels in a limited 2234 fashion. This prevents many of the common foot-shooting actions in the 2235 upgrade as well as the limited ability to roll back the kernel across 2236 the ino64 upgrade. Complicated use cases may not work properly, though 2237 enough simpler ones work to allow recovery in most situations. 2238 223920170620: 2240 Switch back to the BSDL dtc (Device Tree Compiler). Set WITH_GPL_DTC 2241 if you require the GPL compiler. 2242 224320170619: 2244 Forward compatibility for the "ino64" project have been committed. This 2245 will allow most new binaries to run on older kernels in a limited 2246 fashion. This prevents many of the common foot-shooting actions in the 2247 upgrade as well as the limited ability to roll back the kernel across 2248 the ino64 upgrade. Complicated use cases may not work properly, though 2249 enough simpler ones work to allow recovery in most situations. 2250 225120170618: 2252 The internal ABI used for communication between the NFS kernel modules 2253 was changed by r320085, so __FreeBSD_version was bumped to 2254 ensure all the NFS related modules are updated together. 2255 225620170617: 2257 The ABI of struct event was changed by extending the data 2258 member to 64bit and adding ext fields. For upgrade, same 2259 precautions as for the entry 20170523 "ino64" must be 2260 followed. 2261 226220170531: 2263 The GNU roff toolchain has been removed from base. To render manpages 2264 which are not supported by mandoc(1), man(1) can fallback on GNU roff 2265 from ports (and recommends to install it). 2266 To render roff(7) documents, consider using GNU roff from ports or the 2267 heirloom doctools roff toolchain from ports via pkg install groff or 2268 via pkg install heirloom-doctools. 2269 227020170524: 2271 The ath(4) and ath_hal(4) modules now build piecemeal to allow for 2272 smaller runtime footprint builds. This is useful for embedded systems 2273 which only require one chipset support. 2274 2275 If you load it as a module, make sure this is in /boot/loader.conf: 2276 2277 if_ath_load="YES" 2278 2279 This will load the HAL, all chip/RF backends and if_ath_pci. 2280 If you have if_ath_pci in /boot/loader.conf, ensure it is after 2281 if_ath or it will not load any HAL chipset support. 2282 2283 If you want to selectively load things (eg on cheaper ARM/MIPS 2284 platforms where RAM is at a premium) you should: 2285 2286 * load ath_hal 2287 * load the chip modules in question 2288 * load ath_rate, ath_dfs 2289 * load ath_main 2290 * load if_ath_pci and/or if_ath_ahb depending upon your particular 2291 bus bind type - this is where probe/attach is done. 2292 2293 For further comments/feedback, poke adrian@ . 2294 229520170523: 2296 The "ino64" 64-bit inode project has been committed, which extends 2297 a number of types to 64 bits. Upgrading in place requires care and 2298 adherence to the documented upgrade procedure. 2299 2300 If using a custom kernel configuration ensure that the 2301 COMPAT_FREEBSD11 option is included (as during the upgrade the 2302 system will be running the ino64 kernel with the existing world). 2303 2304 For the safest in-place upgrade begin by removing previous build 2305 artifacts via "rm -rf /usr/obj/*". Then, carefully follow the full 2306 procedure documented below under the heading "To rebuild everything and 2307 install it on the current system." Specifically, a reboot is required 2308 after installing the new kernel before installing world. While an 2309 installworld normally works by accident from multiuser after rebooting 2310 the proper kernel, there are many cases where this will fail across this 2311 upgrade and installworld from single user is required. 2312 231320170424: 2314 The NATM framework including the en(4), fatm(4), hatm(4), and 2315 patm(4) devices has been removed. Consumers should plan a 2316 migration before the end-of-life date for FreeBSD 11. 2317 231820170420: 2319 GNU diff has been replaced by a BSD licensed diff. Some features of GNU 2320 diff has not been implemented, if those are needed a newer version of 2321 GNU diff is available via the diffutils package under the gdiff name. 2322 232320170413: 2324 As of r316810 for ipfilter, keep frags is no longer assumed when 2325 keep state is specified in a rule. r316810 aligns ipfilter with 2326 documentation in man pages separating keep frags from keep state. 2327 This allows keep state to be specified without forcing keep frags 2328 and allows keep frags to be specified independently of keep state. 2329 To maintain previous behaviour, also specify keep frags with 2330 keep state (as documented in ipf.conf.5). 2331 233220170407: 2333 arm64 builds now use the base system LLD 4.0.0 linker by default, 2334 instead of requiring that the aarch64-binutils port or package be 2335 installed. To continue using aarch64-binutils, set 2336 CROSS_BINUTILS_PREFIX=/usr/local/aarch64-freebsd/bin . 2337 233820170405: 2339 The UDP optimization in entry 20160818 that added the sysctl 2340 net.inet.udp.require_l2_bcast has been reverted. L2 broadcast 2341 packets will no longer be treated as L3 broadcast packets. 2342 234320170331: 2344 Binds and sends to the loopback addresses, IPv6 and IPv4, will now 2345 use any explicitly assigned loopback address available in the jail 2346 instead of using the first assigned address of the jail. 2347 234820170329: 2349 The ctl.ko module no longer implements the iSCSI target frontend: 2350 cfiscsi.ko does instead. 2351 2352 If building cfiscsi.ko as a kernel module, the module can be loaded 2353 via one of the following methods: 2354 - `cfiscsi_load="YES"` in loader.conf(5). 2355 - Add `cfiscsi` to `$kld_list` in rc.conf(5). 2356 - ctladm(8)/ctld(8), when compiled with iSCSI support 2357 (`WITH_ISCSI=yes` in src.conf(5)) 2358 2359 Please see cfiscsi(4) for more details. 2360 236120170316: 2362 The mmcsd.ko module now additionally depends on geom_flashmap.ko. 2363 Also, mmc.ko and mmcsd.ko need to be a matching pair built from the 2364 same source (previously, the dependency of mmcsd.ko on mmc.ko was 2365 missing, but mmcsd.ko now will refuse to load if it is incompatible 2366 with mmc.ko). 2367 236820170315: 2369 The syntax of ipfw(8) named states was changed to avoid ambiguity. 2370 If you have used named states in the firewall rules, you need to modify 2371 them after installworld and before rebooting. Now named states must 2372 be prefixed with colon. 2373 237420170311: 2375 The old drm (sys/dev/drm/) drivers for i915 and radeon have been 2376 removed as the userland we provide cannot use them. The KMS version 2377 (sys/dev/drm2) supports the same hardware. 2378 237920170302: 2380 Clang, llvm, lldb, compiler-rt and libc++ have been upgraded to 4.0.0. 2381 Please see the 20141231 entry below for information about prerequisites 2382 and upgrading, if you are not already using clang 3.5.0 or higher. 2383 238420170221: 2385 The code that provides support for ZFS .zfs/ directory functionality 2386 has been reimplemented. It's not possible now to create a snapshot 2387 by mkdir under .zfs/snapshot/. That should be the only user visible 2388 change. 2389 239020170216: 2391 EISA bus support has been removed. The WITH_EISA option is no longer 2392 valid. 2393 239420170215: 2395 MCA bus support has been removed. 2396 239720170127: 2398 The WITH_LLD_AS_LD / WITHOUT_LLD_AS_LD build knobs have been renamed 2399 WITH_LLD_IS_LD / WITHOUT_LLD_IS_LD, for consistency with CLANG_IS_CC. 2400 240120170112: 2402 The EM_MULTIQUEUE kernel configuration option is deprecated now that 2403 the em(4) driver conforms to iflib specifications. 2404 240520170109: 2406 The igb(4), em(4) and lem(4) ethernet drivers are now implemented via 2407 IFLIB. If you have a custom kernel configuration that excludes em(4) 2408 but you use igb(4), you need to re-add em(4) to your custom 2409 configuration. 2410 241120161217: 2412 Clang, llvm, lldb, compiler-rt and libc++ have been upgraded to 3.9.1. 2413 Please see the 20141231 entry below for information about prerequisites 2414 and upgrading, if you are not already using clang 3.5.0 or higher. 2415 241620161124: 2417 Clang, llvm, lldb, compiler-rt and libc++ have been upgraded to 3.9.0. 2418 Please see the 20141231 entry below for information about prerequisites 2419 and upgrading, if you are not already using clang 3.5.0 or higher. 2420 242120161119: 2422 The layout of the pmap structure has changed for powerpc to put the pmap 2423 statistics at the front for all CPU variations. libkvm(3) and all tools 2424 that link against it need to be recompiled. 2425 242620161030: 2427 isl(4) and cyapa(4) drivers now require a new driver, 2428 chromebook_platform(4), to work properly on Chromebook-class hardware. 2429 On other types of hardware the drivers may need to be configured using 2430 device hints. Please see the corresponding manual pages for details. 2431 243220161017: 2433 The urtwn(4) driver was merged into rtwn(4) and now consists of 2434 rtwn(4) main module + rtwn_usb(4) and rtwn_pci(4) bus-specific 2435 parts. 2436 Also, firmware for RTL8188CE was renamed due to possible name 2437 conflict (rtwnrtl8192cU(B) -> rtwnrtl8192cE(B)) 2438 243920161015: 2440 GNU rcs has been removed from base. It is available as packages: 2441 - rcs: Latest GPLv3 GNU rcs version. 2442 - rcs57: Copy of the latest version of GNU rcs (GPLv2) before it was 2443 removed from base. 2444 244520161008: 2446 Use of the cc_cdg, cc_chd, cc_hd, or cc_vegas congestion control 2447 modules now requires that the kernel configuration contain the 2448 TCP_HHOOK option. (This option is included in the GENERIC kernel.) 2449 245020161003: 2451 The WITHOUT_ELFCOPY_AS_OBJCOPY src.conf(5) knob has been retired. 2452 ELF Tool Chain's elfcopy is always installed as /usr/bin/objcopy. 2453 245420160924: 2455 Relocatable object files with the extension of .So have been renamed 2456 to use an extension of .pico instead. The purpose of this change is 2457 to avoid a name clash with shared libraries on case-insensitive file 2458 systems. On those file systems, foo.So is the same file as foo.so. 2459 246020160918: 2461 GNU rcs has been turned off by default. It can (temporarily) be built 2462 again by adding WITH_RCS knob in src.conf. 2463 Otherwise, GNU rcs is available from packages: 2464 - rcs: Latest GPLv3 GNU rcs version. 2465 - rcs57: Copy of the latest version of GNU rcs (GPLv2) from base. 2466 246720160918: 2468 The backup_uses_rcs functionality has been removed from rc.subr. 2469 247020160908: 2471 The queue(3) debugging macro, QUEUE_MACRO_DEBUG, has been split into 2472 two separate components, QUEUE_MACRO_DEBUG_TRACE and 2473 QUEUE_MACRO_DEBUG_TRASH. Define both for the original 2474 QUEUE_MACRO_DEBUG behavior. 2475 247620160824: 2477 r304787 changed some ioctl interfaces between the iSCSI userspace 2478 programs and the kernel. ctladm, ctld, iscsictl, and iscsid must be 2479 rebuilt to work with new kernels. __FreeBSD_version has been bumped 2480 to 1200005. 2481 248220160818: 2483 The UDP receive code has been updated to only treat incoming UDP 2484 packets that were addressed to an L2 broadcast address as L3 2485 broadcast packets. It is not expected that this will affect any 2486 standards-conforming UDP application. The new behaviour can be 2487 disabled by setting the sysctl net.inet.udp.require_l2_bcast to 2488 0. 2489 249020160818: 2491 Remove the openbsd_poll system call. 2492 __FreeBSD_version has been bumped because of this. 2493 249420160708: 2495 The stable/11 branch has been created from head@r302406. 2496 2497After branch N is created, entries older than the N-2 branch point are removed 2498from this file. After stable/14 is branched and current becomes FreeBSD 15, 2499entries older than stable/12 branch point will be removed from current's 2500UPDATING file. 2501 2502COMMON ITEMS: 2503 2504 General Notes 2505 ------------- 2506 Sometimes, obscure build problems are the result of environment 2507 poisoning. This can happen because the make utility reads its 2508 environment when searching for values for global variables. To run 2509 your build attempts in an "environmental clean room", prefix all make 2510 commands with 'env -i '. See the env(1) manual page for more details. 2511 Occasionally a build failure will occur with "make -j" due to a race 2512 condition. If this happens try building again without -j, and please 2513 report a bug if it happens consistently. 2514 2515 When upgrading from one major version to another it is generally best to 2516 upgrade to the latest code in the currently installed branch first, then 2517 do an upgrade to the new branch. This is the best-tested upgrade path, 2518 and has the highest probability of being successful. Please try this 2519 approach if you encounter problems with a major version upgrade. Since 2520 the stable 4.x branch point, one has generally been able to upgrade from 2521 anywhere in the most recent stable branch to head / current (or even the 2522 last couple of stable branches). See the top of this file when there's 2523 an exception. 2524 2525 The update process will emit an error on an attempt to perform a build 2526 or install from a FreeBSD version below the earliest supported version. 2527 When updating from an older version the update should be performed one 2528 major release at a time, including running `make delete-old` at each 2529 step. 2530 2531 When upgrading a live system, having a root shell around before 2532 installing anything can help undo problems. Not having a root shell 2533 around can lead to problems if pam has changed too much from your 2534 starting point to allow continued authentication after the upgrade. 2535 2536 This file should be read as a log of events. When a later event changes 2537 information of a prior event, the prior event should not be deleted. 2538 Instead, a pointer to the entry with the new information should be 2539 placed in the old entry. Readers of this file should also sanity check 2540 older entries before relying on them blindly. Authors of new entries 2541 should write them with this in mind. 2542 2543 ZFS notes 2544 --------- 2545 When upgrading the boot ZFS pool to a new version (via zpool upgrade), 2546 always follow these three steps: 2547 2548 1) recompile and reinstall the ZFS boot loader and boot block 2549 (this is part of "make buildworld" and "make installworld") 2550 2551 2) update the ZFS boot block on your boot drive (only required when 2552 doing a zpool upgrade): 2553 2554 When booting on x86 via BIOS, use the following to update the ZFS boot 2555 block on the freebsd-boot partition of a GPT partitioned drive ada0: 2556 gpart bootcode -p /boot/gptzfsboot -i $N ada0 2557 The value $N will typically be 1. For EFI booting, see EFI notes. 2558 2559 3) zpool upgrade the root pool. New bootblocks will work with old 2560 pools, but not vice versa, so they need to be updated before any 2561 zpool upgrade. 2562 2563 Non-boot pools do not need these updates. 2564 2565 EFI notes 2566 --------- 2567 2568 There are two locations the boot loader can be installed into. The 2569 current location (and the default) is \efi\freebsd\loader.efi and using 2570 efibootmgr(8) to configure it. The old location, that must be used on 2571 deficient systems that don't honor efibootmgr(8) protocols, is the 2572 fallback location of \EFI\BOOT\BOOTxxx.EFI. Generally, you will copy 2573 /boot/loader.efi to this location, but on systems installed a long time 2574 ago the ESP may be too small and /boot/boot1.efi may be needed unless 2575 the ESP has been expanded in the meantime. 2576 2577 Recent systems will have the ESP mounted on /boot/efi, but older ones 2578 may not have it mounted at all, or mounted in a different 2579 location. Older arm SD images with MBR used /boot/msdos as the 2580 mountpoint. The ESP is a MSDOS filesystem. 2581 2582 The EFI boot loader rarely needs to be updated. For ZFS booting, 2583 however, you must update loader.efi before you do 'zpool upgrade' the 2584 root zpool, otherwise the old loader.efi may reject the upgraded zpool 2585 since it does not automatically understand some new features. 2586 2587 See loader.efi(8) and uefi(8) for more details. 2588 2589 To build a kernel 2590 ----------------- 2591 If you are updating from a prior version of FreeBSD (even one just 2592 a few days old), you should follow this procedure. It is the most 2593 failsafe as it uses a /usr/obj tree with a fresh mini-buildworld, 2594 2595 make kernel-toolchain 2596 make -DALWAYS_CHECK_MAKE buildkernel KERNCONF=YOUR_KERNEL_HERE 2597 make -DALWAYS_CHECK_MAKE installkernel KERNCONF=YOUR_KERNEL_HERE 2598 2599 If you are running kernel modules from ports, see FOOTNOTE [1]. 2600 2601 To test a kernel once 2602 --------------------- 2603 If you just want to boot a kernel once (because you are not sure 2604 if it works, or if you want to boot a known bad kernel to provide 2605 debugging information) run 2606 make installkernel KERNCONF=YOUR_KERNEL_HERE KODIR=/boot/testkernel 2607 nextboot -k testkernel 2608 2609 To rebuild everything and install it on the current system. 2610 ----------------------------------------------------------- 2611 # Note: sometimes if you are running current you gotta do more than 2612 # is listed here if you are upgrading from a really old current. 2613 2614 <make sure you have good level 0 dumps> [2] 2615 make buildworld 2616 <make sure any needed PORTS_MODULES are set> [1] 2617 make buildkernel KERNCONF=YOUR_KERNEL_HERE 2618 make installkernel KERNCONF=YOUR_KERNEL_HERE 2619 <reboot in single user> [3] 2620 etcupdate -p [5] 2621 make installworld 2622 etcupdate [4] 2623 make delete-old [6] 2624 <reboot> 2625 2626 To cross-install current onto a separate partition 2627 -------------------------------------------------- 2628 # In this approach we use a separate partition to hold 2629 # current's root, 'usr', and 'var' directories. A partition 2630 # holding "/", "/usr" and "/var" should be about 2GB in 2631 # size. 2632 2633 <make sure you have good level 0 dumps> 2634 <boot into -stable> 2635 make buildworld 2636 make buildkernel KERNCONF=YOUR_KERNEL_HERE [1] 2637 <maybe newfs current's root partition> 2638 <mount current's root partition on directory ${CURRENT_ROOT}> 2639 make installworld DESTDIR=${CURRENT_ROOT} -DDB_FROM_SRC 2640 make distribution DESTDIR=${CURRENT_ROOT} # if newfs'd 2641 make installkernel KERNCONF=YOUR_KERNEL_HERE DESTDIR=${CURRENT_ROOT} 2642 cp /etc/fstab ${CURRENT_ROOT}/etc/fstab # if newfs'd 2643 <edit ${CURRENT_ROOT}/etc/fstab to mount "/" from the correct partition> 2644 <reboot into current> 2645 <do a "native" rebuild/install as described in the previous section> 2646 <maybe install compatibility libraries from ports/misc/compat*> 2647 <reboot> 2648 2649 2650 To upgrade in-place from stable to current 2651 ---------------------------------------------- 2652 <make sure you have good level 0 dumps> [2] 2653 make buildworld [9] 2654 <make sure any needed PORTS_MODULES are set> [1] 2655 make buildkernel KERNCONF=YOUR_KERNEL_HERE [8] 2656 make installkernel KERNCONF=YOUR_KERNEL_HERE 2657 <reboot in single user> [3] 2658 etcupdate -p [5] 2659 make installworld 2660 etcupdate [4] 2661 make delete-old [6] 2662 <reboot> 2663 2664 Make sure that you've read the UPDATING file to understand the 2665 tweaks to various things you need. At this point in the life 2666 cycle of current, things change often and you are on your own 2667 to cope. The defaults can also change, so please read ALL of 2668 the UPDATING entries. 2669 2670 Also, if you are tracking -current, you must be subscribed to 2671 freebsd-current@freebsd.org. Make sure that before you update 2672 your sources that you have read and understood all the recent 2673 messages there. If in doubt, please track -stable which has 2674 much fewer pitfalls. 2675 2676FOOTNOTES: 2677 2678 [1] If you have third party modules, such as drm-kmod or vmware, you 2679 should disable them at this point so they don't crash your system on 2680 reboot. Alternatively, you should rebuild all the modules you have in 2681 your system and install them as well. If you are running -current, you 2682 should seriously consider placing all sources to all the modules for 2683 your system (or symlinks to them) in /usr/local/sys/modules so this 2684 happens automatically. If all your modules come from ports, then adding 2685 the port origin directories to PORTS_MODULES instead is also automatic 2686 and effective, eg: 2687 PORTS_MODULES+=graphics/drm-kmod graphics/nvidia-drm-kmod 2688 2689 [2] To make complete dumps on zfs(4), use bectl(8), which 2690 creates bootable snapshots of configurable depth that are 2691 selectable via the bootloader. For ufs(4), use dump(8) and 2692 restore(8). 2693 2694 [3] From the bootblocks, boot -s, and then do 2695 fsck -p 2696 mount -u / 2697 mount -a 2698 sh /etc/rc.d/zfs start # mount zfs filesystem, if needed 2699 cd src # full path to source 2700 adjkerntz -i # if CMOS is wall time 2701 Also, when doing a major release upgrade, it is required that you boot 2702 into single user mode to do the installworld. 2703 2704 [4] Note: This step is non-optional. Failure to do this step 2705 can result in a significant reduction in the functionality of the 2706 system. Attempting to do it by hand is not recommended and those 2707 that pursue this avenue should read this file carefully, as well 2708 as the archives of freebsd-current and freebsd-hackers mailing lists 2709 for potential gotchas. See etcupdate(8) for more information. 2710 2711 [5] Usually this step is a no-op. However, from time to time 2712 you may need to do this if you get unknown user in the following 2713 step. 2714 2715 [6] This only deletes old files and directories. Old libraries 2716 can be deleted by "make delete-old-libs", but you have to make 2717 sure that no program is using those libraries anymore. 2718 2719 [8] The new kernel must be able to run existing binaries used by an 2720 installworld. When upgrading across major versions, the new kernel's 2721 configuration must include the correct COMPAT_FREEBSD<n> option for 2722 existing binaries (e.g. COMPAT_FREEBSD11 to run 11.x binaries). Failure 2723 to do so may leave you with a system that is hard to boot to recover. A 2724 GENERIC kernel will include suitable compatibility options to run 2725 binaries from older branches. Note that the ability to run binaries 2726 from unsupported branches is not guaranteed. 2727 2728 Make sure that you merge any new devices from GENERIC since the 2729 last time you updated your kernel config file. Options also 2730 change over time, so you may need to adjust your custom kernels 2731 for these as well. 2732 2733 [9] If CPUTYPE is defined in your /etc/make.conf, make sure to use the 2734 "?=" instead of the "=" assignment operator, so that buildworld can 2735 override the CPUTYPE if it needs to. 2736 2737 MAKEOBJDIRPREFIX must be defined in an environment variable, and 2738 not on the command line, or in /etc/make.conf. buildworld will 2739 warn if it is improperly defined. 2740FORMAT: 2741 2742This file contains a list, in reverse chronological order, of major 2743breakages in tracking -current. It is not guaranteed to be a complete 2744list of such breakages, and only contains entries since September 23, 2011. 2745If you need to see UPDATING entries from before that date, you will need 2746to fetch an UPDATING file from an older FreeBSD release. 2747 2748Copyright information: 2749 2750Copyright 1998-2009 M.
