1 Updating Information for FreeBSD current users. 2 3This file is maintained and copyrighted by M. Warner Losh <[email protected]>. 4See end of file for further details. For commonly done items, please see the 5COMMON ITEMS: section later in the file. These instructions assume that you 6basically know what you are doing. If not, then please consult the FreeBSD 7handbook: 8 9 https://www.freebsd.org/doc/en_US.ISO8859-1/books/handbook/makeworld.html 10 11Items affecting the ports and packages system can be found in 12/usr/ports/UPDATING. Please read that file before running portupgrade. 13 14NOTE TO PEOPLE WHO THINK THAT FreeBSD 13.x IS SLOW: 15 FreeBSD 13.x has many debugging features turned on, in both the kernel 16 and userland. These features attempt to detect incorrect use of 17 system primitives, and encourage loud failure through extra sanity 18 checking and fail stop semantics. They also substantially impact 19 system performance. If you want to do performance measurement, 20 benchmarking, and optimization, you'll want to turn them off. This 21 includes various WITNESS- related kernel options, INVARIANTS, malloc 22 debugging flags in userland, and various verbose features in the 23 kernel. Many developers choose to disable these features on build 24 machines to maximize performance. (To completely disable malloc 25 debugging, define MALLOC_PRODUCTION in /etc/make.conf, or to merely 26 disable the most expensive debugging functionality run 27 "ln -s 'abort:false,junk:false' /etc/malloc.conf".) 28 2920200810: 30 r364092 modified the internal ABI used between the kernel NFS 31 modules. As such, all of these modules need to be rebuilt 32 from sources, so a version bump was done. 33 3420200807: 35 Makefile.inc has been updated to work around the issue documented in 36 20200729. It was a case where the optimization of using symbolic links 37 to point to binaries created a situation where we'd run new binaries 38 with old libraries starting midway through the installworld process. 39 4020200729: 41 r363679 has redefined some undefined behavior in regcomp(3); notably, 42 extraneous escapes of most ordinary characters will no longer be 43 accepted. An exp-run has identified all of the problems with this in 44 ports, but other non-ports software may need extra escapes removed to 45 continue to function. 46 47 Because of this change, installworld may encounter the following error 48 from rtld: Undefined symbol "regcomp@FBSD_1.6" -- It is imperative that 49 you do not halt installworld. Instead, let it run to completion (whether 50 successful or not) and run installworld once more. 51 5220200627: 53 A new implementation of bc and dc has been imorted in r362681. This 54 implementation corrects non-conformant behavior of the previous bc 55 and adds GNU bc compatible options. It offers a number of extensions, 56 is much faster on large values, and has support for message catalogs 57 (a number of languages are already supported, contributions of further 58 languages welcome). The option WITHOUT_GH_BC can be used to build the 59 world with the previous versions of bc and dc. 60 6120200625: 62 r362639 changed the internal API used between the NFS kernel modules. 63 As such, they all need to be rebuilt from sources. 64 6520200613: 66 r362158 changed the arguments for VFS_CHECKEXP(). As such, any 67 out of tree file systems need to be modified and rebuilt. 68 Also, any file systems that are modules must be rebuilt. 69 7020200604: 71 read(2) of a directory fd is now rejected by default. root may 72 re-enable it for system root only on non-ZFS filesystems with the 73 security.bsd.allow_read_dir sysctl(8) MIB if 74 security.bsd.suser_enabled=1. 75 76 It may be advised to setup aliases for grep to default to `-d skip` if 77 commonly non-recursively grepping a list that includes directories and 78 the potential for the resulting stderr output is not tolerable. Example 79 aliases are now installed, commented out, in /root/.cshrc and 80 /root/.shrc. 81 8220200523: 83 Clang, llvm, lld, lldb, compiler-rt, libc++, libunwind and openmp have 84 been upgraded to 10.0.1. Please see the 20141231 entry below for 85 information about prerequisites and upgrading, if you are not already 86 using clang 3.5.0 or higher. 87 8820200512: 89 Support for obsolete compilers has been removed from the build system. 90 Clang 6 and GCC 6.4 are the minimum supported versions. 91 9220200424: 93 closefrom(2) has been moved under COMPAT12, and replaced in libc with a 94 stub that calls close_range(2). If using a custom kernel configuration, 95 you may want to ensure that the COMPAT_FREEBSD12 option is included, as 96 a slightly older -CURRENT userland and older FreeBSD userlands may not 97 be functional without closefrom(2). 98 9920200414: 100 Upstream DTS from Linux 5.6 was merged and they now have the SID 101 and THS (Secure ID controller and THermal Sensor) node present. 102 The DTB overlays have now been removed from the tree for the H3/H5 and 103 A64 SoCs and the aw_sid and aw_thermal driver have been updated to 104 deal with upstream DTS. If you are using those overlays you need to 105 remove them from loader.conf and update the DTBs on the FAT partition. 106 10720200310: 108 Clang, llvm, lld, lldb, compiler-rt, libc++, libunwind and openmp have 109 been upgraded to 10.0.0. Please see the 20141231 entry below for 110 information about prerequisites and upgrading, if you are not already 111 using clang 3.5.0 or higher. 112 11320200309: 114 The amd(8) automount daemon has been removed from the source tree. 115 As of FreeBSD 10.1 autofs(5) is the preferred tool for automounting. 116 amd is still available in the sysutils/am-utils port. 117 11820200301: 119 Removed brooktree driver (bktr.4) from the tree. 120 12120200229: 122 The WITH_GPL_DTC option has been removed. The BSD-licenced device tree 123 compiler in usr.bin/dtc is used on all architectures which use dtc, and 124 the GPL dtc is available (if needed) from the sysutils/dtc port. 125 12620200229: 127 The WITHOUT_LLVM_LIBUNWIND option has been removed. LLVM's libunwind 128 is used by all supported CPU architectures. 129 13020200229: 131 GCC 4.2.1 has been removed from the tree. The WITH_GCC, 132 WITH_GCC_BOOTSTRAP, and WITH_GNUCXX options are no longer available. 133 Users who wish to build FreeBSD with GCC must use the external toolchain 134 ports or packages. 135 13620200220: 137 ncurses has been updated to a newer version (6.2-20200215). Given the ABI 138 has changed, users will have to rebuild all the ports that are linked to 139 ncurses. 140 14120200217: 142 The size of struct vnet and the magic cookie have changed. 143 Users need to recompile libkvm and all modules using VIMAGE 144 together with their new kernel. 145 14620200212: 147 Defining the long deprecated NO_CTF, NO_DEBUG_FILES, NO_INSTALLLIB, 148 NO_MAN, NO_PROFILE, and NO_WARNS variables is now an error. Update 149 your Makefiles and scripts to define MK_<var>=no instead as required. 150 151 One exception to this is that program or library Makefiles should 152 define MAN to empty rather than setting MK_MAN=no. 153 15420200108: 155 Clang/LLVM is now the default compiler and LLD the default 156 linker for riscv64. 157 15820200107: 159 make universe no longer uses GCC 4.2.1 on any architectures. 160 Architectures not supported by in-tree Clang/LLVM require an 161 external toolchain package. 162 16320200104: 164 GCC 4.2.1 is now not built by default, as part of the GCC 4.2.1 165 retirement plan. Specifically, the GCC, GCC_BOOTSTRAP, and GNUCXX 166 options default to off for all supported CPU architectures. As a 167 short-term transition aid they may be enabled via WITH_* options. 168 GCC 4.2.1 is expected to be removed from the tree on 2020-03-31. 169 17020200102: 171 Support for armv5 has been disconnected and is being removed. The 172 machine combination MACHINE=arm MACHINE_ARCH=arm is no longer valid. 173 You must now use a MACHINE_ARCH of armv6 or armv7. The default 174 MACHINE_ARCH for MACHINE=arm is now armv7. 175 17620191226: 177 Clang/LLVM is now the default compiler for all powerpc architectures. 178 LLD is now the default linker for powerpc64. The change for powerpc64 179 also includes a change to the ELFv2 ABI, incompatible with the existing 180 ABI. 181 18220191226: 183 Kernel-loadable random(4) modules are no longer unloadable. 184 18520191222: 186 Clang, llvm, lld, lldb, compiler-rt, libc++, libunwind and openmp have 187 been upgraded to 9.0.1. Please see the 20141231 entry below for 188 information about prerequisites and upgrading, if you are not already 189 using clang 3.5.0 or higher. 190 19120191212: 192 r355677 has modified the internal interface used between the 193 NFS modules in the kernel. As such, they must all be upgraded 194 simultaneously. I will do a version bump for this. 195 19620191205: 197 The root certificates of the Mozilla CA Certificate Store have been 198 imported into the base system and can be managed with the certctl(8) 199 utility. If you have installed the security/ca_root_nss port or package 200 with the ETCSYMLINK option (the default), be advised that there may be 201 differences between those included in the port and those included in 202 base due to differences in nss branch used as well as general update 203 frequency. Note also that certctl(8) cannot manage certs in the 204 format used by the security/ca_root_nss port. 205 20620191120: 207 The amd(8) automount daemon has been disabled by default, and will be 208 removed in the future. As of FreeBSD 10.1 the autofs(5) is available 209 for automounting. 210 21120191107: 212 The nctgpio and wbwd drivers have been moved to the superio bus. 213 If you have one of these drivers in a kernel configuration, then 214 you should add device superio to it. If you use one of these drivers 215 as a module and you compile a custom set of modules, then you should 216 add superio to the set. 217 21820191021: 219 KPIs for network drivers to access interface addresses have changed. 220 Users need to recompile NIC driver modules together with kernel. 221 22220191021: 223 The net.link.tap.user_open sysctl no longer prevents user opening of 224 already created /dev/tapNN devices. Access is still controlled by 225 node permissions, just like tun devices. The net.link.tap.user_open 226 sysctl is now used only to allow users to perform devfs cloning of 227 tap devices, and the subsequent open may not succeed if the user is not 228 in the appropriate group. This sysctl may be deprecated/removed 229 completely in the future. 230 23120191009: 232 mips, powerpc, and sparc64 are no longer built as part of 233 universe / tinderbox unless MAKE_OBSOLETE_GCC is defined. If 234 not defined, mips, powerpc, and sparc64 builds will look for 235 the xtoolchain binaries and if installed use them for universe 236 builds. As llvm 9.0 becomes vetted for these architectures, they 237 will be removed from the list. 238 23920191009: 240 Clang, llvm, lld, lldb, compiler-rt, libc++, libunwind and openmp have 241 been upgraded to 9.0.0. Please see the 20141231 entry below for 242 information about prerequisites and upgrading, if you are not already 243 using clang 3.5.0 or higher. 244 24520191003: 246 The hpt27xx, hptmv, hptnr, and hptrr drivers have been removed from 247 GENERIC. They are available as modules and can be loaded by adding 248 to /boot/loader.conf hpt27xx_load="YES", hptmv_load="YES", 249 hptnr_load="YES", or hptrr_load="YES", respectively. 250 25120190913: 252 ntpd no longer by default locks its pages in memory, allowing them 253 to be paged out by the kernel. Use rlimit memlock to restore 254 historic BSD behaviour. For example, add "rlimit memlock 32" 255 to ntp.conf to lock up to 32 MB of ntpd address space in memory. 256 25720190823: 258 Several of ping6's options have been renamed for better consistency 259 with ping. If you use any of -ARWXaghmrtwx, you must update your 260 scripts. See ping6(8) for details. 261 26220190727: 263 The vfs.fusefs.sync_unmount and vfs.fusefs.init_backgrounded sysctls 264 and the "-o sync_unmount" and "-o init_backgrounded" mount options have 265 been removed from mount_fusefs(8). You can safely remove them from 266 your scripts, because they had no effect. 267 268 The vfs.fusefs.fix_broken_io, vfs.fusefs.sync_resize, 269 vfs.fusefs.refresh_size, vfs.fusefs.mmap_enable, 270 vfs.fusefs.reclaim_revoked, and vfs.fusefs.data_cache_invalidate 271 sysctls have been removed. If you felt the need to set any of them to 272 a non-default value, please tell [email protected] why. 273 27420190713: 275 Default permissions on the /var/account/acct file (and copies of it 276 rotated by periodic daily scripts) are changed from 0644 to 0640 277 because the file contains sensitive information that should not be 278 world-readable. If the /var/account directory must be created by 279 rc.d/accounting, the mode used is now 0750. Admins who use the 280 accounting feature are encouraged to change the mode of an existing 281 /var/account directory to 0750 or 0700. 282 28320190620: 284 Entropy collection and the /dev/random device are no longer optional 285 components. The "device random" option has been removed. 286 Implementations of distilling algorithms can still be made loadable 287 with "options RANDOM_LOADABLE" (e.g., random_fortuna.ko). 288 28920190612: 290 Clang, llvm, lld, lldb, compiler-rt, libc++, libunwind and openmp have 291 been upgraded to 8.0.1. Please see the 20141231 entry below for 292 information about prerequisites and upgrading, if you are not already 293 using clang 3.5.0 or higher. 294 29520190608: 296 A fix was applied to i386 kernel modules to avoid panics with 297 dpcpu or vnet. Users need to recompile i386 kernel modules 298 having pcpu or vnet sections or they will refuse to load. 299 30020190513: 301 User-wired pages now have their own counter, 302 vm.stats.vm.v_user_wire_count. The vm.max_wired sysctl was renamed 303 to vm.max_user_wired and changed from an unsigned int to an unsigned 304 long. bhyve VMs wired with the -S are now subject to the user 305 wiring limit; the vm.max_user_wired sysctl may need to be tuned to 306 avoid running into the limit. 307 30820190507: 309 The IPSEC option has been removed from GENERIC. Users requiring 310 ipsec(4) must now load the ipsec(4) kernel module. 311 31220190507: 313 The tap(4) driver has been folded into tun(4), and the module has been 314 renamed to tuntap. You should update any kld_list="if_tap" or 315 kld_list="if_tun" entries in /etc/rc.conf, if_tap_load="YES" or 316 if_tun_load="YES" entries in /boot/loader.conf to load the if_tuntap 317 module instead, and "device tap" or "device tun" entries in kernel 318 config files to select the tuntap device instead. 319 32020190418: 321 The following knobs have been added related to tradeoffs between 322 safe use of the random device and availability in the absence of 323 entropy: 324 325 kern.random.initial_seeding.bypass_before_seeding: tunable; set 326 non-zero to bypass the random device prior to seeding, or zero to 327 block random requests until the random device is initially seeded. 328 For now, set to 1 (unsafe) by default to restore pre-r346250 boot 329 availability properties. 330 331 kern.random.initial_seeding.read_random_bypassed_before_seeding: 332 read-only diagnostic sysctl that is set when bypass is enabled and 333 read_random(9) is bypassed, to enable programmatic handling of this 334 initial condition, if desired. 335 336 kern.random.initial_seeding.arc4random_bypassed_before_seeding: 337 Similar to the above, but for for arc4random(9) initial seeding. 338 339 kern.random.initial_seeding.disable_bypass_warnings: tunable; set 340 non-zero to disable warnings in dmesg when the same conditions are 341 met as for the diagnostic sysctls above. Defaults to zero, i.e., 342 produce warnings in dmesg when the conditions are met. 343 34420190416: 345 The loadable random module KPI has changed; the random_infra_init() 346 routine now requires a 3rd function pointer for a bool (*)(void) 347 method that returns true if the random device is seeded (and 348 therefore unblocked). 349 35020190404: 351 r345895 reverts r320698. This implies that an nfsuserd(8) daemon 352 built from head sources between r320757 (July 6, 2017) and 353 r338192 (Aug. 22, 2018) will not work unless the "-use-udpsock" 354 is added to the command line. 355 nfsuserd daemons built from head sources that are post-r338192 are 356 not affected and should continue to work. 357 35820190320: 359 The fuse(4) module has been renamed to fusefs(4) for consistency with 360 other filesystems. You should update any kld_load="fuse" entries in 361 /etc/rc.conf, fuse_load="YES" entries in /boot/loader.conf, and 362 "options FUSE" entries in kernel config files. 363 36420190304: 365 Clang, llvm, lld, lldb, compiler-rt and libc++ have been upgraded to 366 8.0.0. Please see the 20141231 entry below for information about 367 prerequisites and upgrading, if you are not already using clang 3.5.0 368 or higher. 369 37020190226: 371 geom_uzip(4) depends on the new module xz. If geom_uzip is statically 372 compiled into your custom kernel, add 'device xz' statement to the 373 kernel config. 374 37520190219: 376 drm and drm2 have been removed from the tree. Please see 377 https://wiki.freebsd.org/Graphics for the latest information on 378 migrating to the drm ports. 379 38020190131: 381 Iflib is no longer unconditionally compiled into the kernel. Drivers 382 using iflib and statically compiled into the kernel, now require 383 the 'device iflib' config option. For the same drivers loaded as 384 modules on kernels not having 'device iflib', the iflib.ko module 385 is loaded automatically. 386 38720190125: 388 The IEEE80211_AMPDU_AGE and AH_SUPPORT_AR5416 kernel configuration 389 options no longer exist since r343219 and r343427 respectively; 390 nothing uses them, so they should be just removed from custom 391 kernel config files. 392 39320181230: 394 r342635 changes the way efibootmgr(8) works by requiring users to add 395 the -b (bootnum) parameter for commands where the bootnum was previously 396 specified with each option. For example 'efibootmgr -B 0001' is now 397 'efibootmgr -B -b 0001'. 398 39920181220: 400 r342286 modifies the NFSv4 server so that it obeys vfs.nfsd.nfs_privport 401 in the same as it is applied to NFSv2 and 3. This implies that NFSv4 402 servers that have vfs.nfsd.nfs_privport set will only allow mounts 403 from clients using a reserved port#. Since both the FreeBSD and Linux 404 NFSv4 clients use reserved port#s by default, this should not affect 405 most NFSv4 mounts. 406 40720181219: 408 The XLP config has been removed. We can't support 64-bit atomics in this 409 kernel because it is running in 32-bit mode. XLP users must transition 410 to running a 64-bit kernel (XLP64 or XLPN32). 411 412 The mips GXEMUL support has been removed from FreeBSD. MALTA* + qemu is 413 the preferred emulator today and we don't need two different ones. 414 415 The old sibyte / swarm / Broadcom BCM1250 support has been 416 removed from the mips port. 417 41820181211: 419 Clang, llvm, lld, lldb, compiler-rt and libc++ have been upgraded to 420 7.0.1. Please see the 20141231 entry below for information about 421 prerequisites and upgrading, if you are not already using clang 3.5.0 422 or higher. 423 42420181211: 425 Remove the timed and netdate programs from the base tree. Setting 426 the time with these daemons has been obsolete for over a decade. 427 42820181126: 429 On amd64, arm64 and armv7 (architectures that install LLVM's ld.lld 430 linker as /usr/bin/ld) GNU ld is no longer installed as ld.bfd, as 431 it produces broken binaries when ifuncs are in use. Users needing 432 GNU ld should install the binutils port or package. 433 43420181123: 435 The BSD crtbegin and crtend code has been enabled by default. It has 436 had extensive testing on amd64, arm64, and i386. It can be disabled 437 by building a world with -DWITHOUT_BSD_CRTBEGIN. 438 43920181115: 440 The set of CTM commands (ctm, ctm_smail, ctm_rmail, ctm_dequeue) 441 has been converted to a port (misc/ctm) and will be removed from 442 FreeBSD-13. It is available as a package (ctm) for all supported 443 FreeBSD versions. 444 44520181110: 446 The default newsyslog.conf(5) file has been changed to only include 447 files in /etc/newsyslog.conf.d/ and /usr/local/etc/newsyslog.conf.d/ if 448 the filenames end in '.conf' and do not begin with a '.'. 449 450 You should check the configuration files in these two directories match 451 this naming convention. You can verify which configuration files are 452 being included using the command: 453 $ newsyslog -Nrv 454 45520181015: 456 Ports for the DRM modules have been simplified. Now, amd64 users should 457 just install the drm-kmod port. All others should install 458 drm-legacy-kmod. 459 460 Graphics hardware that's newer than about 2010 usually works with 461 drm-kmod. For hardware older than 2013, however, some users will need 462 to use drm-legacy-kmod if drm-kmod doesn't work for them. Hardware older 463 than 2008 usually only works in drm-legacy-kmod. The graphics team can 464 only commit to hardware made since 2013 due to the complexity of the 465 market and difficulty to test all the older cards effectively. If you 466 have hardware supported by drm-kmod, you are strongly encouraged to use 467 that as you will get better support. 468 469 Other than KPI chasing, drm-legacy-kmod will not be updated. As outlined 470 elsewhere, the drm and drm2 modules will be eliminated from the src base 471 soon (with a limited exception for arm). Please update to the package 472 asap and report any issues to [email protected]. 473 474 Generally, anybody using the drm*-kmod packages should add 475 WITHOUT_DRM_MODULE=t and WITHOUT_DRM2_MODULE=t to avoid nasty 476 cross-threading surprises, especially with automatic driver 477 loading from X11 startup. These will become the defaults in 13-current 478 shortly. 479 48020181012: 481 The ixlv(4) driver has been renamed to iavf(4). As a consequence, 482 custom kernel and module loading configuration files must be updated 483 accordingly. Moreover, interfaces previous presented as ixlvN to the 484 system are now exposed as iavfN and network configuration files must 485 be adjusted as necessary. 486 48720181009: 488 OpenSSL has been updated to version 1.1.1. This update included 489 additional various API changes throughout the base system. It is 490 important to rebuild third-party software after upgrading. The value 491 of __FreeBSD_version has been bumped accordingly. 492 49320181006: 494 The legacy DRM modules and drivers have now been added to the loader's 495 module blacklist, in favor of loading them with kld_list in rc.conf(5). 496 The module blacklist may be overridden with the loader.conf(5) 497 'module_blacklist' variable, but loading them via rc.conf(5) is strongly 498 encouraged. 499 50020181002: 501 The cam(4) based nda(4) driver will be used over nvd(4) by default on 502 powerpc64. You may set 'options NVME_USE_NVD=1' in your kernel conf or 503 loader tunable 'hw.nvme.use_nvd=1' if you wish to use the existing 504 driver. Make sure to edit /boot/etc/kboot.conf and fstab to use the 505 nda device name. 506 50720180913: 508 Reproducible build mode is now on by default, in preparation for 509 FreeBSD 12.0. This eliminates build metadata such as the user, 510 host, and time from the kernel (and uname), unless the working tree 511 corresponds to a modified checkout from a version control system. 512 The previous behavior can be obtained by setting the /etc/src.conf 513 knob WITHOUT_REPRODUCIBLE_BUILD. 514 51520180826: 516 The Yarrow CSPRNG has been removed from the kernel as it has not been 517 supported by its designers since at least 2003. Fortuna has been the 518 default since FreeBSD-11. 519 52020180822: 521 devctl freeze/thaw have gone into the tree, the rc scripts have been 522 updated to use them and devmatch has been changed. You should update 523 kernel, userland and rc scripts all at the same time. 524 52520180818: 526 The default interpreter has been switched from 4th to Lua. 527 LOADER_DEFAULT_INTERP, documented in build(7), will override the default 528 interpreter. If you have custom FORTH code you will need to set 529 LOADER_DEFAULT_INTERP=4th (valid values are 4th, lua or simp) in 530 src.conf for the build. This will create default hard links between 531 loader and loader_4th instead of loader and loader_lua, the new default. 532 If you are using UEFI it will create the proper hard link to loader.efi. 533 534 bhyve uses userboot.so. It remains 4th-only until some issues are solved 535 regarding coexisting with multiple versions of FreeBSD are resolved. 536 53720180815: 538 ls(1) now respects the COLORTERM environment variable used in other 539 systems and software to indicate that a colored terminal is both 540 supported and desired. If ls(1) is suddenly emitting colors, they may 541 be disabled again by either removing the unwanted COLORTERM from your 542 environment, or using `ls --color=never`. The ls(1) specific CLICOLOR 543 may not be observed in a future release. 544 54520180808: 546 The default pager for most commands has been changed to "less". To 547 restore the old behavior, set PAGER="more" and MANPAGER="more -s" in 548 your environment. 549 55020180731: 551 The jedec_ts(4) driver has been removed. A superset of its functionality 552 is available in the jedec_dimm(4) driver, and the manpage for that 553 driver includes migration instructions. If you have "device jedec_ts" 554 in your kernel configuration file, it must be removed. 555 55620180730: 557 amd64/GENERIC now has EFI runtime services, EFIRT, enabled by default. 558 This should have no effect if the kernel is booted via BIOS/legacy boot. 559 EFIRT may be disabled via a loader tunable, efi.rt.disabled, if a system 560 has a buggy firmware that prevents a successful boot due to use of 561 runtime services. 562 56320180727: 564 Atmel AT91RM9200 and AT91SAM9, Cavium CNS 11xx and XScale 565 support has been removed from the tree. These ports were 566 obsolete and/or known to be broken for many years. 567 56820180723: 569 loader.efi has been augmented to participate more fully in the 570 UEFI boot manager protocol. loader.efi will now look at the 571 BootXXXX environment variable to determine if a specific kernel 572 or root partition was specified. XXXX is derived from BootCurrent. 573 efibootmgr(8) manages these standard UEFI variables. 574 57520180720: 576 zfsloader's functionality has now been folded into loader. 577 zfsloader is no longer necessary once you've updated your 578 boot blocks. For a transition period, we will install a 579 hardlink for zfsloader to loader to allow a smooth transition 580 until the boot blocks can be updated (hard link because old 581 zfs boot blocks don't understand symlinks). 582 58320180719: 584 ARM64 now have efifb support, if you want to have serial console 585 on your arm64 board when an screen is connected and the bootloader 586 setup a frame buffer for us to use, just add : 587 boot_serial=YES 588 boot_multicons=YES 589 in /boot/loader.conf 590 For Raspberry Pi 3 (RPI) users, this is needed even if you don't have 591 an screen connected as the firmware will setup a frame buffer are that 592 u-boot will expose as an EFI frame buffer. 593 59420180719: 595 New uid:gid added, ntpd:ntpd (123:123). Be sure to run mergemaster 596 or take steps to update /etc/passwd before doing installworld on 597 existing systems. Do not skip the "mergemaster -Fp" step before 598 installworld, as described in the update procedures near the bottom 599 of this document. Also, rc.d/ntpd now starts ntpd(8) as user ntpd 600 if the new mac_ntpd(4) policy is available, unless ntpd_flags or 601 the ntp config file contain options that change file/dir locations. 602 When such options (e.g., "statsdir" or "crypto") are used, ntpd can 603 still be run as non-root by setting ntpd_user=ntpd in rc.conf, after 604 taking steps to ensure that all required files/dirs are accessible 605 by the ntpd user. 606 60720180717: 608 Big endian arm support has been removed. 609 61020180711: 611 The static environment setup in kernel configs is no longer mutually 612 exclusive with the loader(8) environment by default. In order to 613 restore the previous default behavior of disabling the loader(8) 614 environment if a static environment is present, you must specify 615 loader_env.disabled=1 in the static environment. 616 61720180705: 618 The ABI of syscalls used by management tools like sockstat and 619 netstat has been broken to allow 32-bit binaries to work on 620 64-bit kernels without modification. These programs will need 621 to match the kernel in order to function. External programs may 622 require minor modifications to accommodate a change of type in 623 structures from pointers to 64-bit virtual addresses. 624 62520180702: 626 On i386 and amd64 atomics are now inlined. Out of tree modules using 627 atomics will need to be rebuilt. 628 62920180701: 630 The '%I' format in the kern.corefile sysctl limits the number of 631 core files that a process can generate to the number stored in the 632 debug.ncores sysctl. The '%I' format is replaced by the single digit 633 index. Previously, if all indexes were taken the kernel would overwrite 634 only a core file with the highest index in a filename. 635 Currently the system will create a new core file if there is a free 636 index or if all slots are taken it will overwrite the oldest one. 637 63820180630: 639 Clang, llvm, lld, lldb, compiler-rt and libc++ have been upgraded to 640 6.0.1. Please see the 20141231 entry below for information about 641 prerequisites and upgrading, if you are not already using clang 3.5.0 642 or higher. 643 64420180628: 645 r335753 introduced a new quoting method. However, etc/devd/devmatch.conf 646 needed to be changed to work with it. This change was made with r335763 647 and requires a mergemaster / etcupdate / etc to update the installed 648 file. 649 65020180612: 651 r334930 changed the interface between the NFS modules, so they all 652 need to be rebuilt. r335018 did a __FreeBSD_version bump for this. 653 65420180530: 655 As of r334391 lld is the default amd64 system linker; it is installed 656 as /usr/bin/ld. Kernel build workarounds (see 20180510 entry) are no 657 longer necessary. 658 65920180530: 660 The kernel / userland interface for devinfo changed, so you'll 661 need a new kernel and userland as a pair for it to work (rebuilding 662 lib/libdevinfo is all that's required). devinfo and devmatch will 663 not work, but everything else will when there's a mismatch. 664 66520180523: 666 The on-disk format for hwpmc callchain records has changed to include 667 threadid corresponding to a given record. This changes the field offsets 668 and thus requires that libpmcstat be rebuilt before using a kernel 669 later than r334108. 670 67120180517: 672 The vxge(4) driver has been removed. This driver was introduced into 673 HEAD one week before the Exar left the Ethernet market and is not 674 known to be used. If you have device vxge in your kernel config file 675 it must be removed. 676 67720180510: 678 The amd64 kernel now requires a ld that supports ifunc to produce a 679 working kernel, either lld or a newer binutils. lld is built by default 680 on amd64, and the 'buildkernel' target uses it automatically. However, 681 it is not the default linker, so building the kernel the traditional 682 way requires LD=ld.lld on the command line (or LD=/usr/local/bin/ld for 683 binutils port/package). lld will soon be default, and this requirement 684 will go away. 685 686 NOTE: As of r334391 lld is the default system linker on amd64, and no 687 workaround is necessary. 688 68920180508: 690 The nxge(4) driver has been removed. This driver was for PCI-X 10g 691 cards made by s2io/Neterion. The company was acquired by Exar and 692 no longer sells or supports Ethernet products. If you have device 693 nxge in your kernel config file it must be removed. 694 69520180504: 696 The tz database (tzdb) has been updated to 2018e. This version more 697 correctly models time stamps in time zones with negative DST such as 698 Europe/Dublin (from 1971 on), Europe/Prague (1946/7), and 699 Africa/Windhoek (1994/2017). This does not affect the UT offsets, only 700 time zone abbreviations and the tm_isdst flag. 701 70220180502: 703 The ixgb(4) driver has been removed. This driver was for an early and 704 uncommon legacy PCI 10GbE for a single ASIC, Intel 82597EX. Intel 705 quickly shifted to the long lived ixgbe family. If you have device 706 ixgb in your kernel config file it must be removed. 707 70820180501: 709 The lmc(4) driver has been removed. This was a WAN interface 710 card that was already reportedly rare in 2003, and had an ambiguous 711 license. If you have device lmc in your kernel config file it must 712 be removed. 713 71420180413: 715 Support for Arcnet networks has been removed. If you have device 716 arcnet or device cm in your kernel config file they must be 717 removed. 718 71920180411: 720 Support for FDDI networks has been removed. If you have device 721 fddi or device fpa in your kernel config file they must be 722 removed. 723 72420180406: 725 In addition to supporting RFC 3164 formatted messages, the 726 syslogd(8) service is now capable of parsing RFC 5424 formatted 727 log messages. The main benefit of using RFC 5424 is that clients 728 may now send log messages with timestamps containing year numbers, 729 microseconds and time zone offsets. 730 731 Similarly, the syslog(3) C library function has been altered to 732 send RFC 5424 formatted messages to the local system logging 733 daemon. On systems using syslogd(8), this change should have no 734 negative impact, as long as syslogd(8) and the C library are 735 updated at the same time. On systems using a different system 736 logging daemon, it may be necessary to make configuration 737 adjustments, depending on the software used. 738 739 When using syslog-ng, add the 'syslog-protocol' flag to local 740 input sources to enable parsing of RFC 5424 formatted messages: 741 742 source src { 743 unix-dgram("/var/run/log" flags(syslog-protocol)); 744 } 745 746 When using rsyslog, disable the 'SysSock.UseSpecialParser' option 747 of the 'imuxsock' module to let messages be processed by the 748 regular RFC 3164/5424 parsing pipeline: 749 750 module(load="imuxsock" SysSock.UseSpecialParser="off") 751 752 Do note that these changes only affect communication between local 753 applications and syslogd(8). The format that syslogd(8) uses to 754 store messages on disk or forward messages to other systems 755 remains unchanged. syslogd(8) still uses RFC 3164 for these 756 purposes. Options to customize this behaviour will be added in the 757 future. Utilities that process log files stored in /var/log are 758 thus expected to continue to function as before. 759 760 __FreeBSD_version has been incremented to 1200061 to denote this 761 change. 762 76320180328: 764 Support for token ring networks has been removed. If you 765 have "device token" in your kernel config you should remove 766 it. No device drivers supported token ring. 767 76820180323: 769 makefs was modified to be able to tag ISO9660 El Torito boot catalog 770 entries as EFI instead of overloading the i386 tag as done previously. 771 The amd64 mkisoimages.sh script used to build amd64 ISO images for 772 release was updated to use this. This may mean that makefs must be 773 updated before "make cdrom" can be run in the release directory. This 774 should be as simple as: 775 776 $ cd $SRCDIR/usr.sbin/makefs 777 $ make depend all install 778 77920180212: 780 FreeBSD boot loader enhanced with Lua scripting. It's purely opt-in for 781 now by building WITH_LOADER_LUA and WITHOUT_FORTH in /etc/src.conf. 782 Co-existence for the transition period will come shortly. Booting is a 783 complex environment and test coverage for Lua-enabled loaders has been 784 thin, so it would be prudent to assume it might not work and make 785 provisions for backup boot methods. 786 78720180211: 788 devmatch functionality has been turned on in devd. It will automatically 789 load drivers for unattached devices. This may cause unexpected drivers 790 to be loaded. Please report any problems to current@ and 791 [email protected]. 792 79320180114: 794 Clang, llvm, lld, lldb, compiler-rt and libc++ have been upgraded to 795 6.0.0. Please see the 20141231 entry below for information about 796 prerequisites and upgrading, if you are not already using clang 3.5.0 797 or higher. 798 79920180110: 800 LLVM's lld linker is now used as the FreeBSD/amd64 bootstrap linker. 801 This means it is used to link the kernel and userland libraries and 802 executables, but is not yet installed as /usr/bin/ld by default. 803 804 To revert to ld.bfd as the bootstrap linker, in /etc/src.conf set 805 WITHOUT_LLD_BOOTSTRAP=yes 806 80720180110: 808 On i386, pmtimer has been removed. Its functionality has been folded 809 into apm. It was a no-op on ACPI in current for a while now (but was 810 still needed on i386 in FreeBSD 11 and earlier). Users may need to 811 remove it from kernel config files. 812 81320180104: 814 The use of RSS hash from the network card aka flowid has been 815 disabled by default for lagg(4) as it's currently incompatible with 816 the lacp and loadbalance protocols. 817 818 This can be re-enabled by setting the following in loader.conf: 819 net.link.lagg.default_use_flowid="1" 820 82120180102: 822 The SW_WATCHDOG option is no longer necessary to enable the 823 hardclock-based software watchdog if no hardware watchdog is 824 configured. As before, SW_WATCHDOG will cause the software 825 watchdog to be enabled even if a hardware watchdog is configured. 826 82720171215: 828 r326887 fixes the issue described in the 20171214 UPDATING entry. 829 r326888 flips the switch back to building GELI support always. 830 83120171214: 832 r362593 broke ZFS + GELI support for reasons unknown. However, 833 it also broke ZFS support generally, so GELI has been turned off 834 by default as the lesser evil in r326857. If you boot off ZFS and/or 835 GELI, it might not be a good time to update. 836 83720171125: 838 PowerPC users must update loader(8) by rebuilding world before 839 installing a new kernel, as the protocol connecting them has 840 changed. Without the update, loader metadata will not be passed 841 successfully to the kernel and users will have to enter their 842 root partition at the kernel mountroot prompt to continue booting. 843 Newer versions of loader can boot old kernels without issue. 844 84520171110: 846 The LOADER_FIREWIRE_SUPPORT build variable as been renamed to 847 WITH/OUT_LOADER_FIREWIRE. LOADER_{NO_,}GELI_SUPPORT has been renamed 848 to WITH/OUT_LOADER_GELI. 849 85020171106: 851 The naive and non-compliant support of posix_fallocate(2) in ZFS 852 has been removed as of r325320. The system call now returns EINVAL 853 when used on a ZFS file. Although the new behavior complies with the 854 standard, some consumers are not prepared to cope with it. 855 One known victim is lld prior to r325420. 856 85720171102: 858 Building in a FreeBSD src checkout will automatically create object 859 directories now rather than store files in the current directory if 860 'make obj' was not ran. Calling 'make obj' is no longer necessary. 861 This feature can be disabled by setting WITHOUT_AUTO_OBJ=yes in 862 /etc/src-env.conf (not /etc/src.conf), or passing the option in the 863 environment. 864 86520171101: 866 The default MAKEOBJDIR has changed from /usr/obj/<srcdir> for native 867 builds, and /usr/obj/<arch>/<srcdir> for cross-builds, to a unified 868 /usr/obj/<srcdir>/<arch>. This behavior can be changed to the old 869 format by setting WITHOUT_UNIFIED_OBJDIR=yes in /etc/src-env.conf, 870 the environment, or with -DWITHOUT_UNIFIED_OBJDIR when building. 871 The UNIFIED_OBJDIR option is a transitional feature that will be 872 removed for 12.0 release; please migrate to the new format for any 873 tools by looking up the OBJDIR used by 'make -V .OBJDIR' means rather 874 than hardcoding paths. 875 87620171028: 877 The native-xtools target no longer installs the files by default to the 878 OBJDIR. Use the native-xtools-install target with a DESTDIR to install 879 to ${DESTDIR}/${NXTP} where NXTP defaults to /nxb-bin. 880 88120171021: 882 As part of the boot loader infrastructure cleanup, LOADER_*_SUPPORT 883 options are changing from controlling the build if defined / undefined 884 to controlling the build with explicit 'yes' or 'no' values. They will 885 shift to WITH/WITHOUT options to match other options in the system. 886 88720171010: 888 libstand has turned into a private library for sys/boot use only. 889 It is no longer supported as a public interface outside of sys/boot. 890 89120171005: 892 The arm port has split armv6 into armv6 and armv7. armv7 is now 893 a valid TARGET_ARCH/MACHINE_ARCH setting. If you have an armv7 system 894 and are running a kernel from before r324363, you will need to add 895 MACHINE_ARCH=armv7 to 'make buildworld' to do a native build. 896 89720171003: 898 When building multiple kernels using KERNCONF, non-existent KERNCONF 899 files will produce an error and buildkernel will fail. Previously 900 missing KERNCONF files silently failed giving no indication as to 901 why, only to subsequently discover during installkernel that the 902 desired kernel was never built in the first place. 903 90420170912: 905 The default serial number format for CTL LUNs has changed. This will 906 affect users who use /dev/diskid/* device nodes, or whose FibreChannel 907 or iSCSI clients care about their LUNs' serial numbers. Users who 908 require serial number stability should hardcode serial numbers in 909 /etc/ctl.conf . 910 91120170912: 912 For 32-bit arm compiled for hard-float support, soft-floating point 913 binaries now always get their shared libraries from 914 LD_SOFT_LIBRARY_PATH (in the past, this was only used if 915 /usr/libsoft also existed). Only users with a hard-float ld.so, but 916 soft-float everything else should be affected. 917 91820170826: 919 The geli password typed at boot is now hidden. To restore the previous 920 behavior, see geli(8) for configuration options. 921 92220170825: 923 Move PMTUD blackhole counters to TCPSTATS and remove them from bare 924 sysctl values. Minor nit, but requires a rebuild of both world/kernel 925 to complete. 926 92720170814: 928 "make check" behavior (made in ^/head@r295380) has been changed to 929 execute from a limited sandbox, as opposed to executing from 930 ${TESTSDIR}. 931 932 Behavioral changes: 933 - The "beforecheck" and "aftercheck" targets are now specified. 934 - ${CHECKDIR} (added in commit noted above) has been removed. 935 - Legacy behavior can be enabled by setting 936 WITHOUT_MAKE_CHECK_USE_SANDBOX in src.conf(5) or the environment. 937 938 If the limited sandbox mode is enabled, "make check" will execute 939 "make distribution", then install, execute the tests, and clean up the 940 sandbox if successful. 941 942 The "make distribution" and "make install" targets are typically run as 943 root to set appropriate permissions and ownership at installation time. 944 The end-user should set "WITH_INSTALL_AS_USER" in src.conf(5) or the 945 environment if executing "make check" with limited sandbox mode using 946 an unprivileged user. 947 94820170808: 949 Since the switch to GPT disk labels, fsck for UFS/FFS has been 950 unable to automatically find alternate superblocks. As of r322297, 951 the information needed to find alternate superblocks has been 952 moved to the end of the area reserved for the boot block. 953 Filesystems created with a newfs of this vintage or later 954 will create the recovery information. If you have a filesystem 955 created prior to this change and wish to have a recovery block 956 created for your filesystem, you can do so by running fsck in 957 foreground mode (i.e., do not use the -p or -y options). As it 958 starts, fsck will ask ``SAVE DATA TO FIND ALTERNATE SUPERBLOCKS'' 959 to which you should answer yes. 960 96120170728: 962 As of r321665, an NFSv4 server configuration that services 963 Kerberos mounts or clients that do not support the uid/gid in 964 owner/owner_group string capability, must explicitly enable 965 the nfsuserd daemon by adding nfsuserd_enable="YES" to the 966 machine's /etc/rc.conf file. 967 96820170722: 969 Clang, llvm, lldb, compiler-rt and libc++ have been upgraded to 5.0.0. 970 Please see the 20141231 entry below for information about prerequisites 971 and upgrading, if you are not already using clang 3.5.0 or higher. 972 97320170701: 974 WITHOUT_RCMDS is now the default. Set WITH_RCMDS if you need the 975 r-commands (rlogin, rsh, etc.) to be built with the base system. 976 97720170625: 978 The FreeBSD/powerpc platform now uses a 64-bit type for time_t. This is 979 a very major ABI incompatible change, so users of FreeBSD/powerpc must 980 be careful when performing source upgrades. It is best to run 981 'make installworld' from an alternate root system, either a live 982 CD/memory stick, or a temporary root partition. Additionally, all ports 983 must be recompiled. powerpc64 is largely unaffected, except in the case 984 of 32-bit compatibility. All 32-bit binaries will be affected. 985 98620170623: 987 Forward compatibility for the "ino64" project have been committed. This 988 will allow most new binaries to run on older kernels in a limited 989 fashion. This prevents many of the common foot-shooting actions in the 990 upgrade as well as the limited ability to roll back the kernel across 991 the ino64 upgrade. Complicated use cases may not work properly, though 992 enough simpler ones work to allow recovery in most situations. 993 99420170620: 995 Switch back to the BSDL dtc (Device Tree Compiler). Set WITH_GPL_DTC 996 if you require the GPL compiler. 997 99820170618: 999 The internal ABI used for communication between the NFS kernel modules 1000 was changed by r320085, so __FreeBSD_version was bumped to 1001 ensure all the NFS related modules are updated together. 1002 100320170617: 1004 The ABI of struct event was changed by extending the data 1005 member to 64bit and adding ext fields. For upgrade, same 1006 precautions as for the entry 20170523 "ino64" must be 1007 followed. 1008 100920170531: 1010 The GNU roff toolchain has been removed from base. To render manpages 1011 which are not supported by mandoc(1), man(1) can fallback on GNU roff 1012 from ports (and recommends to install it). 1013 To render roff(7) documents, consider using GNU roff from ports or the 1014 heirloom doctools roff toolchain from ports via pkg install groff or 1015 via pkg install heirloom-doctools. 1016 101720170524: 1018 The ath(4) and ath_hal(4) modules now build piecemeal to allow for 1019 smaller runtime footprint builds. This is useful for embedded systems 1020 which only require one chipset support. 1021 1022 If you load it as a module, make sure this is in /boot/loader.conf: 1023 1024 if_ath_load="YES" 1025 1026 This will load the HAL, all chip/RF backends and if_ath_pci. 1027 If you have if_ath_pci in /boot/loader.conf, ensure it is after 1028 if_ath or it will not load any HAL chipset support. 1029 1030 If you want to selectively load things (eg on ye cheape ARM/MIPS 1031 platforms where RAM is at a premium) you should: 1032 1033 * load ath_hal 1034 * load the chip modules in question 1035 * load ath_rate, ath_dfs 1036 * load ath_main 1037 * load if_ath_pci and/or if_ath_ahb depending upon your particular 1038 bus bind type - this is where probe/attach is done. 1039 1040 For further comments/feedback, poke adrian@ . 1041 104220170523: 1043 The "ino64" 64-bit inode project has been committed, which extends 1044 a number of types to 64 bits. Upgrading in place requires care and 1045 adherence to the documented upgrade procedure. 1046 1047 If using a custom kernel configuration ensure that the 1048 COMPAT_FREEBSD11 option is included (as during the upgrade the 1049 system will be running the ino64 kernel with the existing world). 1050 1051 For the safest in-place upgrade begin by removing previous build 1052 artifacts via "rm -rf /usr/obj/*". Then, carefully follow the full 1053 procedure documented below under the heading "To rebuild everything and 1054 install it on the current system." Specifically, a reboot is required 1055 after installing the new kernel before installing world. While an 1056 installworld normally works by accident from multiuser after rebooting 1057 the proper kernel, there are many cases where this will fail across this 1058 upgrade and installworld from single user is required. 1059 106020170424: 1061 The NATM framework including the en(4), fatm(4), hatm(4), and 1062 patm(4) devices has been removed. Consumers should plan a 1063 migration before the end-of-life date for FreeBSD 11. 1064 106520170420: 1066 GNU diff has been replaced by a BSD licensed diff. Some features of GNU 1067 diff has not been implemented, if those are needed a newer version of 1068 GNU diff is available via the diffutils package under the gdiff name. 1069 107020170413: 1071 As of r316810 for ipfilter, keep frags is no longer assumed when 1072 keep state is specified in a rule. r316810 aligns ipfilter with 1073 documentation in man pages separating keep frags from keep state. 1074 This allows keep state to be specified without forcing keep frags 1075 and allows keep frags to be specified independently of keep state. 1076 To maintain previous behaviour, also specify keep frags with 1077 keep state (as documented in ipf.conf.5). 1078 107920170407: 1080 arm64 builds now use the base system LLD 4.0.0 linker by default, 1081 instead of requiring that the aarch64-binutils port or package be 1082 installed. To continue using aarch64-binutils, set 1083 CROSS_BINUTILS_PREFIX=/usr/local/aarch64-freebsd/bin . 1084 108520170405: 1086 The UDP optimization in entry 20160818 that added the sysctl 1087 net.inet.udp.require_l2_bcast has been reverted. L2 broadcast 1088 packets will no longer be treated as L3 broadcast packets. 1089 109020170331: 1091 Binds and sends to the loopback addresses, IPv6 and IPv4, will now 1092 use any explicitly assigned loopback address available in the jail 1093 instead of using the first assigned address of the jail. 1094 109520170329: 1096 The ctl.ko module no longer implements the iSCSI target frontend: 1097 cfiscsi.ko does instead. 1098 1099 If building cfiscsi.ko as a kernel module, the module can be loaded 1100 via one of the following methods: 1101 - `cfiscsi_load="YES"` in loader.conf(5). 1102 - Add `cfiscsi` to `$kld_list` in rc.conf(5). 1103 - ctladm(8)/ctld(8), when compiled with iSCSI support 1104 (`WITH_ISCSI=yes` in src.conf(5)) 1105 1106 Please see cfiscsi(4) for more details. 1107 110820170316: 1109 The mmcsd.ko module now additionally depends on geom_flashmap.ko. 1110 Also, mmc.ko and mmcsd.ko need to be a matching pair built from the 1111 same source (previously, the dependency of mmcsd.ko on mmc.ko was 1112 missing, but mmcsd.ko now will refuse to load if it is incompatible 1113 with mmc.ko). 1114 111520170315: 1116 The syntax of ipfw(8) named states was changed to avoid ambiguity. 1117 If you have used named states in the firewall rules, you need to modify 1118 them after installworld and before rebooting. Now named states must 1119 be prefixed with colon. 1120 112120170311: 1122 The old drm (sys/dev/drm/) drivers for i915 and radeon have been 1123 removed as the userland we provide cannot use them. The KMS version 1124 (sys/dev/drm2) supports the same hardware. 1125 112620170302: 1127 Clang, llvm, lldb, compiler-rt and libc++ have been upgraded to 4.0.0. 1128 Please see the 20141231 entry below for information about prerequisites 1129 and upgrading, if you are not already using clang 3.5.0 or higher. 1130 113120170221: 1132 The code that provides support for ZFS .zfs/ directory functionality 1133 has been reimplemented. It's not possible now to create a snapshot 1134 by mkdir under .zfs/snapshot/. That should be the only user visible 1135 change. 1136 113720170216: 1138 EISA bus support has been removed. The WITH_EISA option is no longer 1139 valid. 1140 114120170215: 1142 MCA bus support has been removed. 1143 114420170127: 1145 The WITH_LLD_AS_LD / WITHOUT_LLD_AS_LD build knobs have been renamed 1146 WITH_LLD_IS_LD / WITHOUT_LLD_IS_LD, for consistency with CLANG_IS_CC. 1147 114820170112: 1149 The EM_MULTIQUEUE kernel configuration option is deprecated now that 1150 the em(4) driver conforms to iflib specifications. 1151 115220170109: 1153 The igb(4), em(4) and lem(4) ethernet drivers are now implemented via 1154 IFLIB. If you have a custom kernel configuration that excludes em(4) 1155 but you use igb(4), you need to re-add em(4) to your custom 1156 configuration. 1157 115820161217: 1159 Clang, llvm, lldb, compiler-rt and libc++ have been upgraded to 3.9.1. 1160 Please see the 20141231 entry below for information about prerequisites 1161 and upgrading, if you are not already using clang 3.5.0 or higher. 1162 116320161124: 1164 Clang, llvm, lldb, compiler-rt and libc++ have been upgraded to 3.9.0. 1165 Please see the 20141231 entry below for information about prerequisites 1166 and upgrading, if you are not already using clang 3.5.0 or higher. 1167 116820161119: 1169 The layout of the pmap structure has changed for powerpc to put the pmap 1170 statistics at the front for all CPU variations. libkvm(3) and all tools 1171 that link against it need to be recompiled. 1172 117320161030: 1174 isl(4) and cyapa(4) drivers now require a new driver, 1175 chromebook_platform(4), to work properly on Chromebook-class hardware. 1176 On other types of hardware the drivers may need to be configured using 1177 device hints. Please see the corresponding manual pages for details. 1178 117920161017: 1180 The urtwn(4) driver was merged into rtwn(4) and now consists of 1181 rtwn(4) main module + rtwn_usb(4) and rtwn_pci(4) bus-specific 1182 parts. 1183 Also, firmware for RTL8188CE was renamed due to possible name 1184 conflict (rtwnrtl8192cU(B) -> rtwnrtl8192cE(B)) 1185 118620161015: 1187 GNU rcs has been removed from base. It is available as packages: 1188 - rcs: Latest GPLv3 GNU rcs version. 1189 - rcs57: Copy of the latest version of GNU rcs (GPLv2) before it was 1190 removed from base. 1191 119220161008: 1193 Use of the cc_cdg, cc_chd, cc_hd, or cc_vegas congestion control 1194 modules now requires that the kernel configuration contain the 1195 TCP_HHOOK option. (This option is included in the GENERIC kernel.) 1196 119720161003: 1198 The WITHOUT_ELFCOPY_AS_OBJCOPY src.conf(5) knob has been retired. 1199 ELF Tool Chain's elfcopy is always installed as /usr/bin/objcopy. 1200 120120160924: 1202 Relocatable object files with the extension of .So have been renamed 1203 to use an extension of .pico instead. The purpose of this change is 1204 to avoid a name clash with shared libraries on case-insensitive file 1205 systems. On those file systems, foo.So is the same file as foo.so. 1206 120720160918: 1208 GNU rcs has been turned off by default. It can (temporarily) be built 1209 again by adding WITH_RCS knob in src.conf. 1210 Otherwise, GNU rcs is available from packages: 1211 - rcs: Latest GPLv3 GNU rcs version. 1212 - rcs57: Copy of the latest version of GNU rcs (GPLv2) from base. 1213 121420160918: 1215 The backup_uses_rcs functionality has been removed from rc.subr. 1216 121720160908: 1218 The queue(3) debugging macro, QUEUE_MACRO_DEBUG, has been split into 1219 two separate components, QUEUE_MACRO_DEBUG_TRACE and 1220 QUEUE_MACRO_DEBUG_TRASH. Define both for the original 1221 QUEUE_MACRO_DEBUG behavior. 1222 122320160824: 1224 r304787 changed some ioctl interfaces between the iSCSI userspace 1225 programs and the kernel. ctladm, ctld, iscsictl, and iscsid must be 1226 rebuilt to work with new kernels. __FreeBSD_version has been bumped 1227 to 1200005. 1228 122920160818: 1230 The UDP receive code has been updated to only treat incoming UDP 1231 packets that were addressed to an L2 broadcast address as L3 1232 broadcast packets. It is not expected that this will affect any 1233 standards-conforming UDP application. The new behaviour can be 1234 disabled by setting the sysctl net.inet.udp.require_l2_bcast to 1235 0. 1236 123720160818: 1238 Remove the openbsd_poll system call. 1239 __FreeBSD_version has been bumped because of this. 1240 124120160708: 1242 The stable/11 branch has been created from head@r302406. 1243 124420160622: 1245 The libc stub for the pipe(2) system call has been replaced with 1246 a wrapper that calls the pipe2(2) system call and the pipe(2) 1247 system call is now only implemented by the kernels that include 1248 "options COMPAT_FREEBSD10" in their config file (this is the 1249 default). Users should ensure that this option is enabled in 1250 their kernel or upgrade userspace to r302092 before upgrading their 1251 kernel. 1252 125320160527: 1254 CAM will now strip leading spaces from SCSI disks' serial numbers. 1255 This will affect users who create UFS filesystems on SCSI disks using 1256 those disk's diskid device nodes. For example, if /etc/fstab 1257 previously contained a line like 1258 "/dev/diskid/DISK-%20%20%20%20%20%20%20ABCDEFG0123456", you should 1259 change it to "/dev/diskid/DISK-ABCDEFG0123456". Users of geom 1260 transforms like gmirror may also be affected. ZFS users should 1261 generally be fine. 1262 126320160523: 1264 The bitstring(3) API has been updated with new functionality and 1265 improved performance. But it is binary-incompatible with the old API. 1266 Objects built with the new headers may not be linked against objects 1267 built with the old headers. 1268 126920160520: 1270 The brk and sbrk functions have been removed from libc on arm64. 1271 Binutils from ports has been updated to not link to these 1272 functions and should be updated to the latest version before 1273 installing a new libc. 1274 127520160517: 1276 The armv6 port now defaults to hard float ABI. Limited support 1277 for running both hardfloat and soft float on the same system 1278 is available using the libraries installed with -DWITH_LIBSOFT. 1279 This has only been tested as an upgrade path for installworld 1280 and packages may fail or need manual intervention to run. New 1281 packages will be needed. 1282 1283 To update an existing self-hosted armv6hf system, you must add 1284 TARGET_ARCH=armv6 on the make command line for both the build 1285 and the install steps. 1286 128720160510: 1288 Kernel modules compiled outside of a kernel build now default to 1289 installing to /boot/modules instead of /boot/kernel. Many kernel 1290 modules built this way (such as those in ports) already overrode 1291 KMODDIR explicitly to install into /boot/modules. However, 1292 manually building and installing a module from /sys/modules will 1293 now install to /boot/modules instead of /boot/kernel. 1294 129520160414: 1296 The CAM I/O scheduler has been committed to the kernel. There should be 1297 no user visible impact. This does enable NCQ Trim on ada SSDs. While the 1298 list of known rogues that claim support for this but actually corrupt 1299 data is believed to be complete, be on the lookout for data 1300 corruption. The known rogue list is believed to be complete: 1301 1302 o Crucial MX100, M550 drives with MU01 firmware. 1303 o Micron M510 and M550 drives with MU01 firmware. 1304 o Micron M500 prior to MU07 firmware 1305 o Samsung 830, 840, and 850 all firmwares 1306 o FCCT M500 all firmwares 1307 1308 Crucial has firmware http://www.crucial.com/usa/en/support-ssd-firmware 1309 with working NCQ TRIM. For Micron branded drives, see your sales rep for 1310 updated firmware. Black listed drives will work correctly because these 1311 drives work correctly so long as no NCQ TRIMs are sent to them. Given 1312 this list is the same as found in Linux, it's believed there are no 1313 other rogues in the market place. All other models from the above 1314 vendors work. 1315 1316 To be safe, if you are at all concerned, you can quirk each of your 1317 drives to prevent NCQ from being sent by setting: 1318 kern.cam.ada.X.quirks="0x2" 1319 in loader.conf. If the drive requires the 4k sector quirk, set the 1320 quirks entry to 0x3. 1321 132220160330: 1323 The FAST_DEPEND build option has been removed and its functionality is 1324 now the one true way. The old mkdep(1) style of 'make depend' has 1325 been removed. See 20160311 for further details. 1326 132720160317: 1328 Resource range types have grown from unsigned long to uintmax_t. All 1329 drivers, and anything using libdevinfo, need to be recompiled. 1330 133120160311: 1332 WITH_FAST_DEPEND is now enabled by default for in-tree and out-of-tree 1333 builds. It no longer runs mkdep(1) during 'make depend', and the 1334 'make depend' stage can safely be skipped now as it is auto ran 1335 when building 'make all' and will generate all SRCS and DPSRCS before 1336 building anything else. Dependencies are gathered at compile time with 1337 -MF flags kept in separate .depend files per object file. Users should 1338 run 'make cleandepend' once if using -DNO_CLEAN to clean out older 1339 stale .depend files. 1340 134120160306: 1342 On amd64, clang 3.8.0 can now insert sections of type AMD64_UNWIND into 1343 kernel modules. Therefore, if you load any kernel modules at boot time, 1344 please install the boot loaders after you install the kernel, but before 1345 rebooting, e.g.: 1346 1347 make buildworld 1348 make buildkernel KERNCONF=YOUR_KERNEL_HERE 1349 make installkernel KERNCONF=YOUR_KERNEL_HERE 1350 make -C sys/boot install 1351 <reboot in single user> 1352 1353 Then follow the usual steps, described in the General Notes section, 1354 below. 1355 135620160305: 1357 Clang, llvm, lldb and compiler-rt have been upgraded to 3.8.0. Please 1358 see the 20141231 entry below for information about prerequisites and 1359 upgrading, if you are not already using clang 3.5.0 or higher. 1360 136120160301: 1362 The AIO subsystem is now a standard part of the kernel. The 1363 VFS_AIO kernel option and aio.ko kernel module have been removed. 1364 Due to stability concerns, asynchronous I/O requests are only 1365 permitted on sockets and raw disks by default. To enable 1366 asynchronous I/O requests on all file types, set the 1367 vfs.aio.enable_unsafe sysctl to a non-zero value. 1368 136920160226: 1370 The ELF object manipulation tool objcopy is now provided by the 1371 ELF Tool Chain project rather than by GNU binutils. It should be a 1372 drop-in replacement, with the addition of arm64 support. The 1373 (temporary) src.conf knob WITHOUT_ELFCOPY_AS_OBJCOPY knob may be set 1374 to obtain the GNU version if necessary. 1375 137620160129: 1377 Building ZFS pools on top of zvols is prohibited by default. That 1378 feature has never worked safely; it's always been prone to deadlocks. 1379 Using a zvol as the backing store for a VM guest's virtual disk will 1380 still work, even if the guest is using ZFS. Legacy behavior can be 1381 restored by setting vfs.zfs.vol.recursive=1. 1382 138320160119: 1384 The NONE and HPN patches has been removed from OpenSSH. They are 1385 still available in the security/openssh-portable port. 1386 138720160113: 1388 With the addition of ypldap(8), a new _ypldap user is now required 1389 during installworld. "mergemaster -p" can be used to add the user 1390 prior to installworld, as documented in the handbook. 1391 139220151216: 1393 The tftp loader (pxeboot) now uses the option root-path directive. As a 1394 consequence it no longer looks for a pxeboot.4th file on the tftp 1395 server. Instead it uses the regular /boot infrastructure as with the 1396 other loaders. 1397 139820151211: 1399 The code to start recording plug and play data into the modules has 1400 been committed. While the old tools will properly build a new kernel, 1401 a number of warnings about "unknown metadata record 4" will be produced 1402 for an older kldxref. To avoid such warnings, make sure to rebuild 1403 the kernel toolchain (or world). Make sure that you have r292078 or 1404 later when trying to build 292077 or later before rebuilding. 1405 140620151207: 1407 Debug data files are now built by default with 'make buildworld' and 1408 installed with 'make installworld'. This facilitates debugging but 1409 requires more disk space both during the build and for the installed 1410 world. Debug files may be disabled by setting WITHOUT_DEBUG_FILES=yes 1411 in src.conf(5). 1412 141320151130: 1414 r291527 changed the internal interface between the nfsd.ko and 1415 nfscommon.ko modules. As such, they must both be upgraded to-gether. 1416 __FreeBSD_version has been bumped because of this. 1417 141820151108: 1419 Add support for unicode collation strings leads to a change of 1420 order of files listed by ls(1) for example. To get back to the old 1421 behaviour, set LC_COLLATE environment variable to "C". 1422 1423 Databases administrators will need to reindex their databases given 1424 collation results will be different. 1425 1426 Due to a bug in install(1) it is recommended to remove the ancient 1427 locales before running make installworld. 1428 1429 rm -rf /usr/share/locale/* 1430 143120151030: 1432 The OpenSSL has been upgraded to 1.0.2d. Any binaries requiring 1433 libcrypto.so.7 or libssl.so.7 must be recompiled. 1434 143520151020: 1436 Qlogic 24xx/25xx firmware images were updated from 5.5.0 to 7.3.0. 1437 Kernel modules isp_2400_multi and isp_2500_multi were removed and 1438 should be replaced with isp_2400 and isp_2500 modules respectively. 1439 144020151017: 1441 The build previously allowed using 'make -n' to not recurse into 1442 sub-directories while showing what commands would be executed, and 1443 'make -n -n' to recursively show commands. Now 'make -n' will recurse 1444 and 'make -N' will not. 1445 144620151012: 1447 If you specify SENDMAIL_MC or SENDMAIL_CF in make.conf, mergemaster 1448 and etcupdate will now use this file. A custom sendmail.cf is now 1449 updated via this mechanism rather than via installworld. If you had 1450 excluded sendmail.cf in mergemaster.rc or etcupdate.conf, you may 1451 want to remove the exclusion or change it to "always install". 1452 /etc/mail/sendmail.cf is now managed the same way regardless of 1453 whether SENDMAIL_MC/SENDMAIL_CF is used. If you are not using 1454 SENDMAIL_MC/SENDMAIL_CF there should be no change in behavior. 1455 145620151011: 1457 Compatibility shims for legacy ATA device names have been removed. 1458 It includes ATA_STATIC_ID kernel option, kern.cam.ada.legacy_aliases 1459 and kern.geom.raid.legacy_aliases loader tunables, kern.devalias.* 1460 environment variables, /dev/ad* and /dev/ar* symbolic links. 1461 146220151006: 1463 Clang, llvm, lldb, compiler-rt and libc++ have been upgraded to 3.7.0. 1464 Please see the 20141231 entry below for information about prerequisites 1465 and upgrading, if you are not already using clang 3.5.0 or higher. 1466 146720150924: 1468 Kernel debug files have been moved to /usr/lib/debug/boot/kernel/, 1469 and renamed from .symbols to .debug. This reduces the size requirements 1470 on the boot partition or file system and provides consistency with 1471 userland debug files. 1472 1473 When using the supported kernel installation method the 1474 /usr/lib/debug/boot/kernel directory will be renamed (to kernel.old) 1475 as is done with /boot/kernel. 1476 1477 Developers wishing to maintain the historical behavior of installing 1478 debug files in /boot/kernel/ can set KERN_DEBUGDIR="" in src.conf(5). 1479 148020150827: 1481 The wireless drivers had undergone changes that remove the 'parent 1482 interface' from the ifconfig -l output. The rc.d network scripts 1483 used to check presence of a parent interface in the list, so old 1484 scripts would fail to start wireless networking. Thus, etcupdate(3) 1485 or mergemaster(8) run is required after kernel update, to update your 1486 rc.d scripts in /etc. 1487 148820150827: 1489 pf no longer supports 'scrub fragment crop' or 'scrub fragment drop-ovl' 1490 These configurations are now automatically interpreted as 1491 'scrub fragment reassemble'. 1492 149320150817: 1494 Kernel-loadable modules for the random(4) device are back. To use 1495 them, the kernel must have 1496 1497 device random 1498 options RANDOM_LOADABLE 1499 1500 kldload(8) can then be used to load random_fortuna.ko 1501 or random_yarrow.ko. Please note that due to the indirect 1502 function calls that the loadable modules need to provide, 1503 the build-in variants will be slightly more efficient. 1504 1505 The random(4) kernel option RANDOM_DUMMY has been retired due to 1506 unpopularity. It was not all that useful anyway. 1507 150820150813: 1509 The WITHOUT_ELFTOOLCHAIN_TOOLS src.conf(5) knob has been retired. 1510 Control over building the ELF Tool Chain tools is now provided by 1511 the WITHOUT_TOOLCHAIN knob. 1512 151320150810: 1514 The polarity of Pulse Per Second (PPS) capture events with the 1515 uart(4) driver has been corrected. Prior to this change the PPS 1516 "assert" event corresponded to the trailing edge of a positive PPS 1517 pulse and the "clear" event was the leading edge of the next pulse. 1518 1519 As the width of a PPS pulse in a typical GPS receiver is on the 1520 order of 1 millisecond, most users will not notice any significant 1521 difference with this change. 1522 1523 Anyone who has compensated for the historical polarity reversal by 1524 configuring a negative offset equal to the pulse width will need to 1525 remove that workaround. 1526 152720150809: 1528 The default group assigned to /dev/dri entries has been changed 1529 from 'wheel' to 'video' with the id of '44'. If you want to have 1530 access to the dri devices please add yourself to the video group 1531 with: 1532 1533 # pw groupmod video -m $USER 1534 153520150806: 1536 The menu.rc and loader.rc files will now be replaced during 1537 upgrades. Please migrate local changes to menu.rc.local and 1538 loader.rc.local instead. 1539 154020150805: 1541 GNU Binutils versions of addr2line, c++filt, nm, readelf, size, 1542 strings and strip have been removed. The src.conf(5) knob 1543 WITHOUT_ELFTOOLCHAIN_TOOLS no longer provides the binutils tools. 1544 154520150728: 1546 As ZFS requires more kernel stack pages than is the default on some 1547 architectures e.g. i386, it now warns if KSTACK_PAGES is less than 1548 ZFS_MIN_KSTACK_PAGES (which is 4 at the time of writing). 1549 1550 Please consider using 'options KSTACK_PAGES=X' where X is greater 1551 than or equal to ZFS_MIN_KSTACK_PAGES i.e. 4 in such configurations. 1552 155320150706: 1554 sendmail has been updated to 8.15.2. Starting with FreeBSD 11.0 1555 and sendmail 8.15, sendmail uses uncompressed IPv6 addresses by 1556 default, i.e., they will not contain "::". For example, instead 1557 of ::1, it will be 0:0:0:0:0:0:0:1. This permits a zero subnet 1558 to have a more specific match, such as different map entries for 1559 IPv6:0:0 vs IPv6:0. This change requires that configuration 1560 data (including maps, files, classes, custom ruleset, etc.) must 1561 use the same format, so make certain such configuration data is 1562 upgrading. As a very simple check search for patterns like 1563 'IPv6:[0-9a-fA-F:]*::' and 'IPv6::'. To return to the old 1564 behavior, set the m4 option confUSE_COMPRESSED_IPV6_ADDRESSES or 1565 the cf option UseCompressedIPv6Addresses. 1566 156720150630: 1568 The default kernel entropy-processing algorithm is now 1569 Fortuna, replacing Yarrow. 1570 1571 Assuming you have 'device random' in your kernel config 1572 file, the configurations allow a kernel option to override 1573 this default. You may choose *ONE* of: 1574 1575 options RANDOM_YARROW # Legacy /dev/random algorithm. 1576 options RANDOM_DUMMY # Blocking-only driver. 1577 1578 If you have neither, you get Fortuna. For most people, 1579 read no further, Fortuna will give a /dev/random that works 1580 like it always used to, and the difference will be irrelevant. 1581 1582 If you remove 'device random', you get *NO* kernel-processed 1583 entropy at all. This may be acceptable to folks building 1584 embedded systems, but has complications. Carry on reading, 1585 and it is assumed you know what you need. 1586 1587 *PLEASE* read random(4) and random(9) if you are in the 1588 habit of tweaking kernel configs, and/or if you are a member 1589 of the embedded community, wanting specific and not-usual 1590 behaviour from your security subsystems. 1591 1592 NOTE!! If you use RANDOM_DUMMY and/or have no 'device 1593 random', you will NOT have a functioning /dev/random, and 1594 many cryptographic features will not work, including SSH. 1595 You may also find strange behaviour from the random(3) set 1596 of library functions, in particular sranddev(3), srandomdev(3) 1597 and arc4random(3). The reason for this is that the KERN_ARND 1598 sysctl only returns entropy if it thinks it has some to 1599 share, and with RANDOM_DUMMY or no 'device random' this 1600 will never happen. 1601 160220150623: 1603 An additional fix for the issue described in the 20150614 sendmail 1604 entry below has been committed in revision 284717. 1605 160620150616: 1607 FreeBSD's old make (fmake) has been removed from the system. It is 1608 available as the devel/fmake port or via pkg install fmake. 1609 161020150615: 1611 The fix for the issue described in the 20150614 sendmail entry 1612 below has been committed in revision 284436. The work 1613 around described in that entry is no longer needed unless the 1614 default setting is overridden by a confDH_PARAMETERS configuration 1615 setting of '5' or pointing to a 512 bit DH parameter file. 1616 161720150614: 1618 ALLOW_DEPRECATED_ATF_TOOLS/ATFFILE support has been removed from 1619 atf.test.mk (included from bsd.test.mk). Please upgrade devel/atf 1620 and devel/kyua to version 0.20+ and adjust any calling code to work 1621 with Kyuafile and kyua. 1622 162320150614: 1624 The import of openssl to address the FreeBSD-SA-15:10.openssl 1625 security advisory includes a change which rejects handshakes 1626 with DH parameters below 768 bits. sendmail releases prior 1627 to 8.15.2 (not yet released), defaulted to a 512 bit 1628 DH parameter setting for client connections. To work around 1629 this interoperability, sendmail can be configured to use a 1630 2048 bit DH parameter by: 1631 1632 1. Edit /etc/mail/`hostname`.mc 1633 2. If a setting for confDH_PARAMETERS does not exist or 1634 exists and is set to a string beginning with '5', 1635 replace it with '2'. 1636 3. If a setting for confDH_PARAMETERS exists and is set to 1637 a file path, create a new file with: 1638 openssl dhparam -out /path/to/file 2048 1639 4. Rebuild the .cf file: 1640 cd /etc/mail/; make; make install 1641 5. Restart sendmail: 1642 cd /etc/mail/; make restart 1643 1644 A sendmail patch is coming, at which time this file will be 1645 updated. 1646 164720150604: 1648 Generation of legacy formatted entries have been disabled by default 1649 in pwd_mkdb(8), as all base system consumers of the legacy formatted 1650 entries were converted to use the new format by default when the new, 1651 machine independent format have been added and supported since FreeBSD 1652 5.x. 1653 1654 Please see the pwd_mkdb(8) manual page for further details. 1655 165620150525: 1657 Clang and llvm have been upgraded to 3.6.1 release. Please see the 1658 20141231 entry below for information about prerequisites and upgrading, 1659 if you are not already using 3.5.0 or higher. 1660 166120150521: 1662 TI platform code switched to using vendor DTS files and this update 1663 may break existing systems running on Beaglebone, Beaglebone Black, 1664 and Pandaboard: 1665 1666 - dtb files should be regenerated/reinstalled. Filenames are the 1667 same but content is different now 1668 - GPIO addressing was changed, now each GPIO bank (32 pins per bank) 1669 has its own /dev/gpiocX device, e.g. pin 121 on /dev/gpioc0 in old 1670 addressing scheme is now pin 25 on /dev/gpioc3. 1671 - Pandaboard: /etc/ttys should be updated, serial console device is 1672 now /dev/ttyu2, not /dev/ttyu0 1673 167420150501: 1675 soelim(1) from gnu/usr.bin/groff has been replaced by usr.bin/soelim. 1676 If you need the GNU extension from groff soelim(1), install groff 1677 from package: pkg install groff, or via ports: textproc/groff. 1678 167920150423: 1680 chmod, chflags, chown and chgrp now affect symlinks in -R mode as 1681 defined in symlink(7); previously symlinks were silently ignored. 1682 168320150415: 1684 The const qualifier has been removed from iconv(3) to comply with 1685 POSIX. The ports tree is aware of this from r384038 onwards. 1686 168720150416: 1688 Libraries specified by LIBADD in Makefiles must have a corresponding 1689 DPADD_<lib> variable to ensure correct dependencies. This is now 1690 enforced in src.libnames.mk. 1691 169220150324: 1693 From legacy ata(4) driver was removed support for SATA controllers 1694 supported by more functional drivers ahci(4), siis(4) and mvs(4). 1695 Kernel modules ataahci and ataadaptec were removed completely, 1696 replaced by ahci and mvs modules respectively. 1697 169820150315: 1699 Clang, llvm and lldb have been upgraded to 3.6.0 release. Please see 1700 the 20141231 entry below for information about prerequisites and 1701 upgrading, if you are not already using 3.5.0 or higher. 1702 170320150307: 1704 The 32-bit PowerPC kernel has been changed to a position-independent 1705 executable. This can only be booted with a version of loader(8) 1706 newer than January 31, 2015, so make sure to update both world and 1707 kernel before rebooting. 1708 170920150217: 1710 If you are running a -CURRENT kernel since r273872 (Oct 30th, 2014), 1711 but before r278950, the RNG was not seeded properly. Immediately 1712 upgrade the kernel to r278950 or later and regenerate any keys (e.g. 1713 ssh keys or openssl keys) that were generated w/ a kernel from that 1714 range. This does not affect programs that directly used /dev/random 1715 or /dev/urandom. All userland uses of arc4random(3) are affected. 1716 171720150210: 1718 The autofs(4) ABI was changed in order to restore binary compatibility 1719 with 10.1-RELEASE. The automountd(8) daemon needs to be rebuilt to work 1720 with the new kernel. 1721 172220150131: 1723 The powerpc64 kernel has been changed to a position-independent 1724 executable. This can only be booted with a new version of loader(8), 1725 so make sure to update both world and kernel before rebooting. 1726 172720150118: 1728 Clang and llvm have been upgraded to 3.5.1 release. This is a bugfix 1729 only release, no new features have been added. Please see the 20141231 1730 entry below for information about prerequisites and upgrading, if you 1731 are not already using 3.5.0. 1732 173320150107: 1734 ELF tools addr2line, elfcopy (strip), nm, size, and strings are now 1735 taken from the ELF Tool Chain project rather than GNU binutils. They 1736 should be drop-in replacements, with the addition of arm64 support. 1737 The WITHOUT_ELFTOOLCHAIN_TOOLS= knob may be used to obtain the 1738 binutils tools, if necessary. See 20150805 for updated information. 1739 174020150105: 1741 The default Unbound configuration now enables remote control 1742 using a local socket. Users who have already enabled the 1743 local_unbound service should regenerate their configuration 1744 by running "service local_unbound setup" as root. 1745 174620150102: 1747 The GNU texinfo and GNU info pages have been removed. 1748 To be able to view GNU info pages please install texinfo from ports. 1749 175020141231: 1751 Clang, llvm and lldb have been upgraded to 3.5.0 release. 1752 1753 As of this release, a prerequisite for building clang, llvm and lldb is 1754 a C++11 capable compiler and C++11 standard library. This means that to 1755 be able to successfully build the cross-tools stage of buildworld, with 1756 clang as the bootstrap compiler, your system compiler or cross compiler 1757 should either be clang 3.3 or later, or gcc 4.8 or later, and your 1758 system C++ library should be libc++, or libdstdc++ from gcc 4.8 or 1759 later. 1760 1761 On any standard FreeBSD 10.x or 11.x installation, where clang and 1762 libc++ are on by default (that is, on x86 or arm), this should work out 1763 of the box. 1764 1765 On 9.x installations where clang is enabled by default, e.g. on x86 and 1766 powerpc, libc++ will not be enabled by default, so libc++ should be 1767 built (with clang) and installed first. If both clang and libc++ are 1768 missing, build clang first, then use it to build libc++. 1769 1770 On 8.x and earlier installations, upgrade to 9.x first, and then follow 1771 the instructions for 9.x above. 1772 1773 Sparc64 and mips users are unaffected, as they still use gcc 4.2.1 by 1774 default, and do not build clang. 1775 1776 Many embedded systems are resource constrained, and will not be able to 1777 build clang in a reasonable time, or in some cases at all. In those 1778 cases, cross building bootable systems on amd64 is a workaround. 1779 1780 This new version of clang introduces a number of new warnings, of which 1781 the following are most likely to appear: 1782 1783 -Wabsolute-value 1784 1785 This warns in two cases, for both C and C++: 1786 * When the code is trying to take the absolute value of an unsigned 1787 quantity, which is effectively a no-op, and almost never what was 1788 intended. The code should be fixed, if at all possible. If you are 1789 sure that the unsigned quantity can be safely cast to signed, without 1790 loss of information or undefined behavior, you can add an explicit 1791 cast, or disable the warning. 1792 1793 * When the code is trying to take an absolute value, but the called 1794 abs() variant is for the wrong type, which can lead to truncation. 1795 If you want to disable the warning instead of fixing the code, please 1796 make sure that truncation will not occur, or it might lead to unwanted 1797 side-effects. 1798 1799 -Wtautological-undefined-compare and 1800 -Wundefined-bool-conversion 1801 1802 These warn when C++ code is trying to compare 'this' against NULL, while 1803 'this' should never be NULL in well-defined C++ code. However, there is 1804 some legacy (pre C++11) code out there, which actively abuses this 1805 feature, which was less strictly defined in previous C++ versions. 1806 1807 Squid and openjdk do this, for example. The warning can be turned off 1808 for C++98 and earlier, but compiling the code in C++11 mode might result 1809 in unexpected behavior; for example, the parts of the program that are 1810 unreachable could be optimized away. 1811 181220141222: 1813 The old NFS client and server (kernel options NFSCLIENT, NFSSERVER) 1814 kernel sources have been removed. The .h files remain, since some 1815 utilities include them. This will need to be fixed later. 1816 If "mount -t oldnfs ..." is attempted, it will fail. 1817 If the "-o" option on mountd(8), nfsd(8) or nfsstat(1) is used, 1818 the utilities will report errors. 1819 182020141121: 1821 The handling of LOCAL_LIB_DIRS has been altered to skip addition of 1822 directories to top level SUBDIR variable when their parent 1823 directory is included in LOCAL_DIRS. Users with build systems with 1824 such hierarchies and without SUBDIR entries in the parent 1825 directory Makefiles should add them or add the directories to 1826 LOCAL_DIRS. 1827 182820141109: 1829 faith(4) and faithd(8) have been removed from the base system. Faith 1830 has been obsolete for a very long time. 1831 183220141104: 1833 vt(4), the new console driver, is enabled by default. It brings 1834 support for Unicode and double-width characters, as well as 1835 support for UEFI and integration with the KMS kernel video 1836 drivers. 1837 1838 You may need to update your console settings in /etc/rc.conf, 1839 most probably the keymap. During boot, /etc/rc.d/syscons will 1840 indicate what you need to do. 1841 1842 vt(4) still has issues and lacks some features compared to 1843 syscons(4). See the wiki for up-to-date information: 1844 https://wiki.freebsd.org/Newcons 1845 1846 If you want to keep using syscons(4), you can do so by adding 1847 the following line to /boot/loader.conf: 1848 kern.vty=sc 1849 185020141102: 1851 pjdfstest has been integrated into kyua as an opt-in test suite. 1852 Please see share/doc/pjdfstest/README for more details on how to 1853 execute it. 1854 185520141009: 1856 gperf has been removed from the base system for architectures 1857 that use clang. Ports that require gperf will obtain it from the 1858 devel/gperf port. 1859 186020140923: 1861 pjdfstest has been moved from tools/regression/pjdfstest to 1862 contrib/pjdfstest . 1863 186420140922: 1865 At svn r271982, The default linux compat kernel ABI has been adjusted 1866 to 2.6.18 in support of the linux-c6 compat ports infrastructure 1867 update. If you wish to continue using the linux-f10 compat ports, 1868 add compat.linux.osrelease=2.6.16 to your local sysctl.conf. Users are 1869 encouraged to update their linux-compat packages to linux-c6 during 1870 their next update cycle. 1871 187220140729: 1873 The ofwfb driver, used to provide a graphics console on PowerPC when 1874 using vt(4), no longer allows mmap() of all physical memory. This 1875 will prevent Xorg on PowerPC with some ATI graphics cards from 1876 initializing properly unless x11-servers/xorg-server is updated to 1877 1.12.4_8 or newer. 1878 187920140723: 1880 The xdev targets have been converted to using TARGET and 1881 TARGET_ARCH instead of XDEV and XDEV_ARCH. 1882 188320140719: 1884 The default unbound configuration has been modified to address 1885 issues with reverse lookups on networks that use private 1886 address ranges. If you use the local_unbound service, run 1887 "service local_unbound setup" as root to regenerate your 1888 configuration, then "service local_unbound reload" to load the 1889 new configuration. 1890 189120140709: 1892 The GNU texinfo and GNU info pages are not built and installed 1893 anymore, WITH_INFO knob has been added to allow to built and install 1894 them again. 1895 UPDATE: see 20150102 entry on texinfo's removal 1896 189720140708: 1898 The GNU readline library is now an INTERNALLIB - that is, it is 1899 statically linked into consumers (GDB and variants) in the base 1900 system, and the shared library is no longer installed. The 1901 devel/readline port is available for third party software that 1902 requires readline. 1903 190420140702: 1905 The Itanium architecture (ia64) has been removed from the list of 1906 known architectures. This is the first step in the removal of the 1907 architecture. 1908 190920140701: 1910 Commit r268115 has added NFSv4.1 server support, merged from 1911 projects/nfsv4.1-server. Since this includes changes to the 1912 internal interfaces between the NFS related modules, a full 1913 build of the kernel and modules will be necessary. 1914 __FreeBSD_version has been bumped. 1915 191620140629: 1917 The WITHOUT_VT_SUPPORT kernel config knob has been renamed 1918 WITHOUT_VT. (The other _SUPPORT knobs have a consistent meaning 1919 which differs from the behaviour controlled by this knob.) 1920 192120140619: 1922 Maximal length of the serial number in CTL was increased from 16 to 1923 64 chars, that breaks ABI. All CTL-related tools, such as ctladm 1924 and ctld, need to be rebuilt to work with a new kernel. 1925 192620140606: 1927 The libatf-c and libatf-c++ major versions were downgraded to 0 and 1928 1 respectively to match the upstream numbers. They were out of 1929 sync because, when they were originally added to FreeBSD, the 1930 upstream versions were not respected. These libraries are private 1931 and not yet built by default, so renumbering them should be a 1932 non-issue. However, unclean source trees will yield broken test 1933 programs once the operator executes "make delete-old-libs" after a 1934 "make installworld". 1935 1936 Additionally, the atf-sh binary was made private by moving it into 1937 /usr/libexec/. Already-built shell test programs will keep the 1938 path to the old binary so they will break after "make delete-old" 1939 is run. 1940 1941 If you are using WITH_TESTS=yes (not the default), wipe the object 1942 tree and rebuild from scratch to prevent spurious test failures. 1943 This is only needed once: the misnumbered libraries and misplaced 1944 binaries have been added to OptionalObsoleteFiles.inc so they will 1945 be removed during a clean upgrade. 1946 194720140512: 1948 Clang and llvm have been upgraded to 3.4.1 release. 1949 195020140508: 1951 We bogusly installed src.opts.mk in /usr/share/mk. This file should 1952 be removed to avoid issues in the future (and has been added to 1953 ObsoleteFiles.inc). 1954 195520140505: 1956 /etc/src.conf now affects only builds of the FreeBSD src tree. In the 1957 past, it affected all builds that used the bsd.*.mk files. The old 1958 behavior was a bug, but people may have relied upon it. To get this 1959 behavior back, you can .include /etc/src.conf from /etc/make.conf 1960 (which is still global and isn't changed). This also changes the 1961 behavior of incremental builds inside the tree of individual 1962 directories. Set MAKESYSPATH to ".../share/mk" to do that. 1963 Although this has survived make universe and some upgrade scenarios, 1964 other upgrade scenarios may have broken. At least one form of 1965 temporary breakage was fixed with MAKESYSPATH settings for buildworld 1966 as well... In cases where MAKESYSPATH isn't working with this 1967 setting, you'll need to set it to the full path to your tree. 1968 1969 One side effect of all this cleaning up is that bsd.compiler.mk 1970 is no longer implicitly included by bsd.own.mk. If you wish to 1971 use COMPILER_TYPE, you must now explicitly include bsd.compiler.mk 1972 as well. 1973 197420140430: 1975 The lindev device has been removed since /dev/full has been made a 1976 standard device. __FreeBSD_version has been bumped. 1977 197820140424: 1979 The knob WITHOUT_VI was added to the base system, which controls 1980 building ex(1), vi(1), etc. Older releases of FreeBSD required ex(1) 1981 in order to reorder files share/termcap and didn't build ex(1) as a 1982 build tool, so building/installing with WITH_VI is highly advised for 1983 build hosts for older releases. 1984 1985 This issue has been fixed in stable/9 and stable/10 in r277022 and 1986 r276991, respectively. 1987 198820140418: 1989 The YES_HESIOD knob has been removed. It has been obsolete for 1990 a decade. Please move to using WITH_HESIOD instead or your builds 1991 will silently lack HESIOD. 1992 199320140405: 1994 The uart(4) driver has been changed with respect to its handling 1995 of the low-level console. Previously the uart(4) driver prevented 1996 any process from changing the baudrate or the CLOCAL and HUPCL 1997 control flags. By removing the restrictions, operators can make 1998 changes to the serial console port without having to reboot. 1999 However, when getty(8) is started on the serial device that is 2000 associated with the low-level console, a misconfigured terminal 2001 line in /etc/ttys will now have a real impact. 2002 Before upgrading the kernel, make sure that /etc/ttys has the 2003 serial console device configured as 3wire without baudrate to 2004 preserve the previous behaviour. E.g: 2005 ttyu0 "/usr/libexec/getty 3wire" vt100 on secure 2006 200720140306: 2008 Support for libwrap (TCP wrappers) in rpcbind was disabled by default 2009 to improve performance. To re-enable it, if needed, run rpcbind 2010 with command line option -W. 2011 201220140226: 2013 Switched back to the GPL dtc compiler due to updates in the upstream 2014 dts files not being supported by the BSDL dtc compiler. You will need 2015 to rebuild your kernel toolchain to pick up the new compiler. Core dumps 2016 may result while building dtb files during a kernel build if you fail 2017 to do so. Set WITHOUT_GPL_DTC if you require the BSDL compiler. 2018 201920140216: 2020 Clang and llvm have been upgraded to 3.4 release. 2021 202220140216: 2023 The nve(4) driver has been removed. Please use the nfe(4) driver 2024 for NVIDIA nForce MCP Ethernet adapters instead. 2025 202620140212: 2027 An ABI incompatibility crept into the libc++ 3.4 import in r261283. 2028 This could cause certain C++ applications using shared libraries built 2029 against the previous version of libc++ to crash. The incompatibility 2030 has now been fixed, but any C++ applications or shared libraries built 2031 between r261283 and r261801 should be recompiled. 2032 203320140204: 2034 OpenSSH will now ignore errors caused by kernel lacking of Capsicum 2035 capability mode support. Please note that enabling the feature in 2036 kernel is still highly recommended. 2037 203820140131: 2039 OpenSSH is now built with sandbox support, and will use sandbox as 2040 the default privilege separation method. This requires Capsicum 2041 capability mode support in kernel. 2042 204320140128: 2044 The libelf and libdwarf libraries have been updated to newer 2045 versions from upstream. Shared library version numbers for 2046 these two libraries were bumped. Any ports or binaries 2047 requiring these two libraries should be recompiled. 2048 __FreeBSD_version is bumped to 1100006. 2049 205020140110: 2051 If a Makefile in a tests/ directory was auto-generating a Kyuafile 2052 instead of providing an explicit one, this would prevent such 2053 Makefile from providing its own Kyuafile in the future during 2054 NO_CLEAN builds. This has been fixed in the Makefiles but manual 2055 intervention is needed to clean an objdir if you use NO_CLEAN: 2056 # find /usr/obj -name Kyuafile | xargs rm -f 2057 205820131213: 2059 The behavior of gss_pseudo_random() for the krb5 mechanism 2060 has changed, for applications requesting a longer random string 2061 than produced by the underlying enctype's pseudo-random() function. 2062 In particular, the random string produced from a session key of 2063 enctype aes256-cts-hmac-sha1-96 or aes256-cts-hmac-sha1-96 will 2064 be different at the 17th octet and later, after this change. 2065 The counter used in the PRF+ construction is now encoded as a 2066 big-endian integer in accordance with RFC 4402. 2067 __FreeBSD_version is bumped to 1100004. 2068 206920131108: 2070 The WITHOUT_ATF build knob has been removed and its functionality 2071 has been subsumed into the more generic WITHOUT_TESTS. If you were 2072 using the former to disable the build of the ATF libraries, you 2073 should change your settings to use the latter. 2074 207520131025: 2076 The default version of mtree is nmtree which is obtained from 2077 NetBSD. The output is generally the same, but may vary 2078 slightly. If you found you need identical output adding 2079 "-F freebsd9" to the command line should do the trick. For the 2080 time being, the old mtree is available as fmtree. 2081 208220131014: 2083 libbsdyml has been renamed to libyaml and moved to /usr/lib/private. 2084 This will break ports-mgmt/pkg. Rebuild the port, or upgrade to pkg 2085 1.1.4_8 and verify bsdyml not linked in, before running "make 2086 delete-old-libs": 2087 # make -C /usr/ports/ports-mgmt/pkg build deinstall install clean 2088 or 2089 # pkg install pkg; ldd /usr/local/sbin/pkg | grep bsdyml 2090 209120131010: 2092 The stable/10 branch has been created in subversion from head 2093 revision r256279. 2094 2095COMMON ITEMS: 2096 2097 General Notes 2098 ------------- 2099 Sometimes, obscure build problems are the result of environment 2100 poisoning. This can happen because the make utility reads its 2101 environment when searching for values for global variables. To run 2102 your build attempts in an "environmental clean room", prefix all make 2103 commands with 'env -i '. See the env(1) manual page for more details. 2104 Occasionally a build failure will occur with "make -j" due to a race 2105 condition. If this happens try building again without -j, and please 2106 report a bug if it happens consistently. 2107 2108 When upgrading from one major version to another it is generally best to 2109 upgrade to the latest code in the currently installed branch first, then 2110 do an upgrade to the new branch. This is the best-tested upgrade path, 2111 and has the highest probability of being successful. Please try this 2112 approach if you encounter problems with a major version upgrade. Since 2113 the stable 4.x branch point, one has generally been able to upgrade from 2114 anywhere in the most recent stable branch to head / current (or even the 2115 last couple of stable branches). See the top of this file when there's 2116 an exception. 2117 2118 The update process will emit an error on an attempt to perform a build 2119 or install from a FreeBSD version below the earliest supported version. 2120 When updating from an older version the update should be performed one 2121 major release at a time, including running `make delete-old` at each 2122 step. 2123 2124 When upgrading a live system, having a root shell around before 2125 installing anything can help undo problems. Not having a root shell 2126 around can lead to problems if pam has changed too much from your 2127 starting point to allow continued authentication after the upgrade. 2128 2129 This file should be read as a log of events. When a later event changes 2130 information of a prior event, the prior event should not be deleted. 2131 Instead, a pointer to the entry with the new information should be 2132 placed in the old entry. Readers of this file should also sanity check 2133 older entries before relying on them blindly. Authors of new entries 2134 should write them with this in mind. 2135 2136 ZFS notes 2137 --------- 2138 When upgrading the boot ZFS pool to a new version, always follow 2139 these two steps: 2140 2141 1.) recompile and reinstall the ZFS boot loader and boot block 2142 (this is part of "make buildworld" and "make installworld") 2143 2144 2.) update the ZFS boot block on your boot drive 2145 2146 The following example updates the ZFS boot block on the first 2147 partition (freebsd-boot) of a GPT partitioned drive ada0: 2148 "gpart bootcode -p /boot/gptzfsboot -i 1 ada0" 2149 2150 Non-boot pools do not need these updates. 2151 2152 To build a kernel 2153 ----------------- 2154 If you are updating from a prior version of FreeBSD (even one just 2155 a few days old), you should follow this procedure. It is the most 2156 failsafe as it uses a /usr/obj tree with a fresh mini-buildworld, 2157 2158 make kernel-toolchain 2159 make -DALWAYS_CHECK_MAKE buildkernel KERNCONF=YOUR_KERNEL_HERE 2160 make -DALWAYS_CHECK_MAKE installkernel KERNCONF=YOUR_KERNEL_HERE 2161 2162 To test a kernel once 2163 --------------------- 2164 If you just want to boot a kernel once (because you are not sure 2165 if it works, or if you want to boot a known bad kernel to provide 2166 debugging information) run 2167 make installkernel KERNCONF=YOUR_KERNEL_HERE KODIR=/boot/testkernel 2168 nextboot -k testkernel 2169 2170 To rebuild everything and install it on the current system. 2171 ----------------------------------------------------------- 2172 # Note: sometimes if you are running current you gotta do more than 2173 # is listed here if you are upgrading from a really old current. 2174 2175 <make sure you have good level 0 dumps> 2176 make buildworld 2177 make buildkernel KERNCONF=YOUR_KERNEL_HERE 2178 make installkernel KERNCONF=YOUR_KERNEL_HERE 2179 [1] 2180 <reboot in single user> [3] 2181 mergemaster -Fp [5] 2182 make installworld 2183 mergemaster -Fi [4] 2184 make delete-old [6] 2185 <reboot> 2186 2187 To cross-install current onto a separate partition 2188 -------------------------------------------------- 2189 # In this approach we use a separate partition to hold 2190 # current's root, 'usr', and 'var' directories. A partition 2191 # holding "/", "/usr" and "/var" should be about 2GB in 2192 # size. 2193 2194 <make sure you have good level 0 dumps> 2195 <boot into -stable> 2196 make buildworld 2197 make buildkernel KERNCONF=YOUR_KERNEL_HERE 2198 <maybe newfs current's root partition> 2199 <mount current's root partition on directory ${CURRENT_ROOT}> 2200 make installworld DESTDIR=${CURRENT_ROOT} -DDB_FROM_SRC 2201 make distribution DESTDIR=${CURRENT_ROOT} # if newfs'd 2202 make installkernel KERNCONF=YOUR_KERNEL_HERE DESTDIR=${CURRENT_ROOT} 2203 cp /etc/fstab ${CURRENT_ROOT}/etc/fstab # if newfs'd 2204 <edit ${CURRENT_ROOT}/etc/fstab to mount "/" from the correct partition> 2205 <reboot into current> 2206 <do a "native" rebuild/install as described in the previous section> 2207 <maybe install compatibility libraries from ports/misc/compat*> 2208 <reboot> 2209 2210 2211 To upgrade in-place from stable to current 2212 ---------------------------------------------- 2213 <make sure you have good level 0 dumps> 2214 make buildworld [9] 2215 make buildkernel KERNCONF=YOUR_KERNEL_HERE [8] 2216 make installkernel KERNCONF=YOUR_KERNEL_HERE 2217 [1] 2218 <reboot in single user> [3] 2219 mergemaster -Fp [5] 2220 make installworld 2221 mergemaster -Fi [4] 2222 make delete-old [6] 2223 <reboot> 2224 2225 Make sure that you've read the UPDATING file to understand the 2226 tweaks to various things you need. At this point in the life 2227 cycle of current, things change often and you are on your own 2228 to cope. The defaults can also change, so please read ALL of 2229 the UPDATING entries. 2230 2231 Also, if you are tracking -current, you must be subscribed to 2232 [email protected]. Make sure that before you update 2233 your sources that you have read and understood all the recent 2234 messages there. If in doubt, please track -stable which has 2235 much fewer pitfalls. 2236 2237 [1] If you have third party modules, such as vmware, you 2238 should disable them at this point so they don't crash your 2239 system on reboot. 2240 2241 [3] From the bootblocks, boot -s, and then do 2242 fsck -p 2243 mount -u / 2244 mount -a 2245 sh /etc/rc.d/zfs start # mount zfs filesystem, if needed 2246 cd src # full path to source 2247 adjkerntz -i # if CMOS is wall time 2248 Also, when doing a major release upgrade, it is required that 2249 you boot into single user mode to do the installworld. 2250 2251 [4] Note: This step is non-optional. Failure to do this step 2252 can result in a significant reduction in the functionality of the 2253 system. Attempting to do it by hand is not recommended and those 2254 that pursue this avenue should read this file carefully, as well 2255 as the archives of freebsd-current and freebsd-hackers mailing lists 2256 for potential gotchas. The -U option is also useful to consider. 2257 See mergemaster(8) for more information. 2258 2259 [5] Usually this step is a no-op. However, from time to time 2260 you may need to do this if you get unknown user in the following 2261 step. It never hurts to do it all the time. You may need to 2262 install a new mergemaster (cd src/usr.sbin/mergemaster && make 2263 install) after the buildworld before this step if you last updated 2264 from current before 20130425 or from -stable before 20130430. 2265 2266 [6] This only deletes old files and directories. Old libraries 2267 can be deleted by "make delete-old-libs", but you have to make 2268 sure that no program is using those libraries anymore. 2269 2270 [8] The new kernel must be able to run existing binaries used by an 2271 installworld. When upgrading across major versions, the new kernel's 2272 configuration must include the correct COMPAT_FREEBSD<n> option for 2273 existing binaries (e.g. COMPAT_FREEBSD11 to run 11.x binaries). Failure 2274 to do so may leave you with a system that is hard to boot to recover. A 2275 GENERIC kernel will include suitable compatibility options to run 2276 binaries from older branches. Note that the ability to run binaries 2277 from unsupported branches is not guaranteed. 2278 2279 Make sure that you merge any new devices from GENERIC since the 2280 last time you updated your kernel config file. Options also 2281 change over time, so you may need to adjust your custom kernels 2282 for these as well. 2283 2284 [9] If CPUTYPE is defined in your /etc/make.conf, make sure to use the 2285 "?=" instead of the "=" assignment operator, so that buildworld can 2286 override the CPUTYPE if it needs to. 2287 2288 MAKEOBJDIRPREFIX must be defined in an environment variable, and 2289 not on the command line, or in /etc/make.conf. buildworld will 2290 warn if it is improperly defined. 2291FORMAT: 2292 2293This file contains a list, in reverse chronological order, of major 2294breakages in tracking -current. It is not guaranteed to be a complete 2295list of such breakages, and only contains entries since September 23, 2011. 2296If you need to see UPDATING entries from before that date, you will need 2297to fetch an UPDATING file from an older FreeBSD release. 2298 2299Copyright information: 2300 2301Copyright 1998-2009 M.
