1 Updating Information for FreeBSD current users. 2 3This file is maintained and copyrighted by M. Warner Losh <imp@freebsd.org>. 4See end of file for further details. For commonly done items, please see the 5COMMON ITEMS: section later in the file. These instructions assume that you 6basically know what you are doing. If not, then please consult the FreeBSD 7handbook: 8 9 https://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 2920200821: 30 r362275 changed the internal API between the kernel RPC and the 31 NFS modules. As such, all the modules must be recompiled from 32 sources. 33 3420200817: 35 r364330 modified the internal API used between the NFS modules. 36 As such, all the NFS modules must be re-compiled from sources. 37 3820200816: 39 Clang, llvm, lld, lldb, compiler-rt, libc++, libunwind and openmp have 40 been upgraded to 11.0.0. Please see the 20141231 entry below for 41 information about prerequisites and upgrading, if you are not already 42 using clang 3.5.0 or higher. 43 4420200810: 45 r364092 modified the internal ABI used between the kernel NFS 46 modules. As such, all of these modules need to be rebuilt 47 from sources, so a version bump was done. 48 4920200807: 50 Makefile.inc has been updated to work around the issue documented in 51 20200729. It was a case where the optimization of using symbolic links 52 to point to binaries created a situation where we'd run new binaries 53 with old libraries starting midway through the installworld process. 54 5520200729: 56 r363679 has redefined some undefined behavior in regcomp(3); notably, 57 extraneous escapes of most ordinary characters will no longer be 58 accepted. An exp-run has identified all of the problems with this in 59 ports, but other non-ports software may need extra escapes removed to 60 continue to function. 61 62 Because of this change, installworld may encounter the following error 63 from rtld: Undefined symbol "regcomp@FBSD_1.6" -- It is imperative that 64 you do not halt installworld. Instead, let it run to completion (whether 65 successful or not) and run installworld once more. 66 6720200627: 68 A new implementation of bc and dc has been imorted in r362681. This 69 implementation corrects non-conformant behavior of the previous bc 70 and adds GNU bc compatible options. It offers a number of extensions, 71 is much faster on large values, and has support for message catalogs 72 (a number of languages are already supported, contributions of further 73 languages welcome). The option WITHOUT_GH_BC can be used to build the 74 world with the previous versions of bc and dc. 75 7620200625: 77 r362639 changed the internal API used between the NFS kernel modules. 78 As such, they all need to be rebuilt from sources. 79 8020200613: 81 r362158 changed the arguments for VFS_CHECKEXP(). As such, any 82 out of tree file systems need to be modified and rebuilt. 83 Also, any file systems that are modules must be rebuilt. 84 8520200604: 86 read(2) of a directory fd is now rejected by default. root may 87 re-enable it for system root only on non-ZFS filesystems with the 88 security.bsd.allow_read_dir sysctl(8) MIB if 89 security.bsd.suser_enabled=1. 90 91 It may be advised to setup aliases for grep to default to `-d skip` if 92 commonly non-recursively grepping a list that includes directories and 93 the potential for the resulting stderr output is not tolerable. Example 94 aliases are now installed, commented out, in /root/.cshrc and 95 /root/.shrc. 96 9720200523: 98 Clang, llvm, lld, lldb, compiler-rt, libc++, libunwind and openmp have 99 been upgraded to 10.0.1. Please see the 20141231 entry below for 100 information about prerequisites and upgrading, if you are not already 101 using clang 3.5.0 or higher. 102 10320200512: 104 Support for obsolete compilers has been removed from the build system. 105 Clang 6 and GCC 6.4 are the minimum supported versions. 106 10720200424: 108 closefrom(2) has been moved under COMPAT12, and replaced in libc with a 109 stub that calls close_range(2). If using a custom kernel configuration, 110 you may want to ensure that the COMPAT_FREEBSD12 option is included, as 111 a slightly older -CURRENT userland and older FreeBSD userlands may not 112 be functional without closefrom(2). 113 11420200414: 115 Upstream DTS from Linux 5.6 was merged and they now have the SID 116 and THS (Secure ID controller and THermal Sensor) node present. 117 The DTB overlays have now been removed from the tree for the H3/H5 and 118 A64 SoCs and the aw_sid and aw_thermal driver have been updated to 119 deal with upstream DTS. If you are using those overlays you need to 120 remove them from loader.conf and update the DTBs on the FAT partition. 121 12220200310: 123 Clang, llvm, lld, lldb, compiler-rt, libc++, libunwind and openmp have 124 been upgraded to 10.0.0. Please see the 20141231 entry below for 125 information about prerequisites and upgrading, if you are not already 126 using clang 3.5.0 or higher. 127 12820200309: 129 The amd(8) automount daemon has been removed from the source tree. 130 As of FreeBSD 10.1 autofs(5) is the preferred tool for automounting. 131 amd is still available in the sysutils/am-utils port. 132 13320200301: 134 Removed brooktree driver (bktr.4) from the tree. 135 13620200229: 137 The WITH_GPL_DTC option has been removed. The BSD-licenced device tree 138 compiler in usr.bin/dtc is used on all architectures which use dtc, and 139 the GPL dtc is available (if needed) from the sysutils/dtc port. 140 14120200229: 142 The WITHOUT_LLVM_LIBUNWIND option has been removed. LLVM's libunwind 143 is used by all supported CPU architectures. 144 14520200229: 146 GCC 4.2.1 has been removed from the tree. The WITH_GCC, 147 WITH_GCC_BOOTSTRAP, and WITH_GNUCXX options are no longer available. 148 Users who wish to build FreeBSD with GCC must use the external toolchain 149 ports or packages. 150 15120200220: 152 ncurses has been updated to a newer version (6.2-20200215). Given the ABI 153 has changed, users will have to rebuild all the ports that are linked to 154 ncurses. 155 15620200217: 157 The size of struct vnet and the magic cookie have changed. 158 Users need to recompile libkvm and all modules using VIMAGE 159 together with their new kernel. 160 16120200212: 162 Defining the long deprecated NO_CTF, NO_DEBUG_FILES, NO_INSTALLLIB, 163 NO_MAN, NO_PROFILE, and NO_WARNS variables is now an error. Update 164 your Makefiles and scripts to define MK_<var>=no instead as required. 165 166 One exception to this is that program or library Makefiles should 167 define MAN to empty rather than setting MK_MAN=no. 168 16920200108: 170 Clang/LLVM is now the default compiler and LLD the default 171 linker for riscv64. 172 17320200107: 174 make universe no longer uses GCC 4.2.1 on any architectures. 175 Architectures not supported by in-tree Clang/LLVM require an 176 external toolchain package. 177 17820200104: 179 GCC 4.2.1 is now not built by default, as part of the GCC 4.2.1 180 retirement plan. Specifically, the GCC, GCC_BOOTSTRAP, and GNUCXX 181 options default to off for all supported CPU architectures. As a 182 short-term transition aid they may be enabled via WITH_* options. 183 GCC 4.2.1 is expected to be removed from the tree on 2020-03-31. 184 18520200102: 186 Support for armv5 has been disconnected and is being removed. The 187 machine combination MACHINE=arm MACHINE_ARCH=arm is no longer valid. 188 You must now use a MACHINE_ARCH of armv6 or armv7. The default 189 MACHINE_ARCH for MACHINE=arm is now armv7. 190 19120191226: 192 Clang/LLVM is now the default compiler for all powerpc architectures. 193 LLD is now the default linker for powerpc64. The change for powerpc64 194 also includes a change to the ELFv2 ABI, incompatible with the existing 195 ABI. 196 19720191226: 198 Kernel-loadable random(4) modules are no longer unloadable. 199 20020191222: 201 Clang, llvm, lld, lldb, compiler-rt, libc++, libunwind and openmp have 202 been upgraded to 9.0.1. Please see the 20141231 entry below for 203 information about prerequisites and upgrading, if you are not already 204 using clang 3.5.0 or higher. 205 20620191212: 207 r355677 has modified the internal interface used between the 208 NFS modules in the kernel. As such, they must all be upgraded 209 simultaneously. I will do a version bump for this. 210 21120191205: 212 The root certificates of the Mozilla CA Certificate Store have been 213 imported into the base system and can be managed with the certctl(8) 214 utility. If you have installed the security/ca_root_nss port or package 215 with the ETCSYMLINK option (the default), be advised that there may be 216 differences between those included in the port and those included in 217 base due to differences in nss branch used as well as general update 218 frequency. Note also that certctl(8) cannot manage certs in the 219 format used by the security/ca_root_nss port. 220 22120191120: 222 The amd(8) automount daemon has been disabled by default, and will be 223 removed in the future. As of FreeBSD 10.1 the autofs(5) is available 224 for automounting. 225 22620191107: 227 The nctgpio and wbwd drivers have been moved to the superio bus. 228 If you have one of these drivers in a kernel configuration, then 229 you should add device superio to it. If you use one of these drivers 230 as a module and you compile a custom set of modules, then you should 231 add superio to the set. 232 23320191021: 234 KPIs for network drivers to access interface addresses have changed. 235 Users need to recompile NIC driver modules together with kernel. 236 23720191021: 238 The net.link.tap.user_open sysctl no longer prevents user opening of 239 already created /dev/tapNN devices. Access is still controlled by 240 node permissions, just like tun devices. The net.link.tap.user_open 241 sysctl is now used only to allow users to perform devfs cloning of 242 tap devices, and the subsequent open may not succeed if the user is not 243 in the appropriate group. This sysctl may be deprecated/removed 244 completely in the future. 245 24620191009: 247 mips, powerpc, and sparc64 are no longer built as part of 248 universe / tinderbox unless MAKE_OBSOLETE_GCC is defined. If 249 not defined, mips, powerpc, and sparc64 builds will look for 250 the xtoolchain binaries and if installed use them for universe 251 builds. As llvm 9.0 becomes vetted for these architectures, they 252 will be removed from the list. 253 25420191009: 255 Clang, llvm, lld, lldb, compiler-rt, libc++, libunwind and openmp have 256 been upgraded to 9.0.0. Please see the 20141231 entry below for 257 information about prerequisites and upgrading, if you are not already 258 using clang 3.5.0 or higher. 259 26020191003: 261 The hpt27xx, hptmv, hptnr, and hptrr drivers have been removed from 262 GENERIC. They are available as modules and can be loaded by adding 263 to /boot/loader.conf hpt27xx_load="YES", hptmv_load="YES", 264 hptnr_load="YES", or hptrr_load="YES", respectively. 265 26620190913: 267 ntpd no longer by default locks its pages in memory, allowing them 268 to be paged out by the kernel. Use rlimit memlock to restore 269 historic BSD behaviour. For example, add "rlimit memlock 32" 270 to ntp.conf to lock up to 32 MB of ntpd address space in memory. 271 27220190823: 273 Several of ping6's options have been renamed for better consistency 274 with ping. If you use any of -ARWXaghmrtwx, you must update your 275 scripts. See ping6(8) for details. 276 27720190727: 278 The vfs.fusefs.sync_unmount and vfs.fusefs.init_backgrounded sysctls 279 and the "-o sync_unmount" and "-o init_backgrounded" mount options have 280 been removed from mount_fusefs(8). You can safely remove them from 281 your scripts, because they had no effect. 282 283 The vfs.fusefs.fix_broken_io, vfs.fusefs.sync_resize, 284 vfs.fusefs.refresh_size, vfs.fusefs.mmap_enable, 285 vfs.fusefs.reclaim_revoked, and vfs.fusefs.data_cache_invalidate 286 sysctls have been removed. If you felt the need to set any of them to 287 a non-default value, please tell asomers@FreeBSD.org why. 288 28920190713: 290 Default permissions on the /var/account/acct file (and copies of it 291 rotated by periodic daily scripts) are changed from 0644 to 0640 292 because the file contains sensitive information that should not be 293 world-readable. If the /var/account directory must be created by 294 rc.d/accounting, the mode used is now 0750. Admins who use the 295 accounting feature are encouraged to change the mode of an existing 296 /var/account directory to 0750 or 0700. 297 29820190620: 299 Entropy collection and the /dev/random device are no longer optional 300 components. The "device random" option has been removed. 301 Implementations of distilling algorithms can still be made loadable 302 with "options RANDOM_LOADABLE" (e.g., random_fortuna.ko). 303 30420190612: 305 Clang, llvm, lld, lldb, compiler-rt, libc++, libunwind and openmp have 306 been upgraded to 8.0.1. Please see the 20141231 entry below for 307 information about prerequisites and upgrading, if you are not already 308 using clang 3.5.0 or higher. 309 31020190608: 311 A fix was applied to i386 kernel modules to avoid panics with 312 dpcpu or vnet. Users need to recompile i386 kernel modules 313 having pcpu or vnet sections or they will refuse to load. 314 31520190513: 316 User-wired pages now have their own counter, 317 vm.stats.vm.v_user_wire_count. The vm.max_wired sysctl was renamed 318 to vm.max_user_wired and changed from an unsigned int to an unsigned 319 long. bhyve VMs wired with the -S are now subject to the user 320 wiring limit; the vm.max_user_wired sysctl may need to be tuned to 321 avoid running into the limit. 322 32320190507: 324 The IPSEC option has been removed from GENERIC. Users requiring 325 ipsec(4) must now load the ipsec(4) kernel module. 326 32720190507: 328 The tap(4) driver has been folded into tun(4), and the module has been 329 renamed to tuntap. You should update any kld_list="if_tap" or 330 kld_list="if_tun" entries in /etc/rc.conf, if_tap_load="YES" or 331 if_tun_load="YES" entries in /boot/loader.conf to load the if_tuntap 332 module instead, and "device tap" or "device tun" entries in kernel 333 config files to select the tuntap device instead. 334 33520190418: 336 The following knobs have been added related to tradeoffs between 337 safe use of the random device and availability in the absence of 338 entropy: 339 340 kern.random.initial_seeding.bypass_before_seeding: tunable; set 341 non-zero to bypass the random device prior to seeding, or zero to 342 block random requests until the random device is initially seeded. 343 For now, set to 1 (unsafe) by default to restore pre-r346250 boot 344 availability properties. 345 346 kern.random.initial_seeding.read_random_bypassed_before_seeding: 347 read-only diagnostic sysctl that is set when bypass is enabled and 348 read_random(9) is bypassed, to enable programmatic handling of this 349 initial condition, if desired. 350 351 kern.random.initial_seeding.arc4random_bypassed_before_seeding: 352 Similar to the above, but for for arc4random(9) initial seeding. 353 354 kern.random.initial_seeding.disable_bypass_warnings: tunable; set 355 non-zero to disable warnings in dmesg when the same conditions are 356 met as for the diagnostic sysctls above. Defaults to zero, i.e., 357 produce warnings in dmesg when the conditions are met. 358 35920190416: 360 The loadable random module KPI has changed; the random_infra_init() 361 routine now requires a 3rd function pointer for a bool (*)(void) 362 method that returns true if the random device is seeded (and 363 therefore unblocked). 364 36520190404: 366 r345895 reverts r320698. This implies that an nfsuserd(8) daemon 367 built from head sources between r320757 (July 6, 2017) and 368 r338192 (Aug. 22, 2018) will not work unless the "-use-udpsock" 369 is added to the command line. 370 nfsuserd daemons built from head sources that are post-r338192 are 371 not affected and should continue to work. 372 37320190320: 374 The fuse(4) module has been renamed to fusefs(4) for consistency with 375 other filesystems. You should update any kld_load="fuse" entries in 376 /etc/rc.conf, fuse_load="YES" entries in /boot/loader.conf, and 377 "options FUSE" entries in kernel config files. 378 37920190304: 380 Clang, llvm, lld, lldb, compiler-rt and libc++ have been upgraded to 381 8.0.0. Please see the 20141231 entry below for information about 382 prerequisites and upgrading, if you are not already using clang 3.5.0 383 or higher. 384 38520190226: 386 geom_uzip(4) depends on the new module xz. If geom_uzip is statically 387 compiled into your custom kernel, add 'device xz' statement to the 388 kernel config. 389 39020190219: 391 drm and drm2 have been removed from the tree. Please see 392 https://wiki.freebsd.org/Graphics for the latest information on 393 migrating to the drm ports. 394 39520190131: 396 Iflib is no longer unconditionally compiled into the kernel. Drivers 397 using iflib and statically compiled into the kernel, now require 398 the 'device iflib' config option. For the same drivers loaded as 399 modules on kernels not having 'device iflib', the iflib.ko module 400 is loaded automatically. 401 40220190125: 403 The IEEE80211_AMPDU_AGE and AH_SUPPORT_AR5416 kernel configuration 404 options no longer exist since r343219 and r343427 respectively; 405 nothing uses them, so they should be just removed from custom 406 kernel config files. 407 40820181230: 409 r342635 changes the way efibootmgr(8) works by requiring users to add 410 the -b (bootnum) parameter for commands where the bootnum was previously 411 specified with each option. For example 'efibootmgr -B 0001' is now 412 'efibootmgr -B -b 0001'. 413 41420181220: 415 r342286 modifies the NFSv4 server so that it obeys vfs.nfsd.nfs_privport 416 in the same as it is applied to NFSv2 and 3. This implies that NFSv4 417 servers that have vfs.nfsd.nfs_privport set will only allow mounts 418 from clients using a reserved port#. Since both the FreeBSD and Linux 419 NFSv4 clients use reserved port#s by default, this should not affect 420 most NFSv4 mounts. 421 42220181219: 423 The XLP config has been removed. We can't support 64-bit atomics in this 424 kernel because it is running in 32-bit mode. XLP users must transition 425 to running a 64-bit kernel (XLP64 or XLPN32). 426 427 The mips GXEMUL support has been removed from FreeBSD. MALTA* + qemu is 428 the preferred emulator today and we don't need two different ones. 429 430 The old sibyte / swarm / Broadcom BCM1250 support has been 431 removed from the mips port. 432 43320181211: 434 Clang, llvm, lld, lldb, compiler-rt and libc++ have been upgraded to 435 7.0.1. Please see the 20141231 entry below for information about 436 prerequisites and upgrading, if you are not already using clang 3.5.0 437 or higher. 438 43920181211: 440 Remove the timed and netdate programs from the base tree. Setting 441 the time with these daemons has been obsolete for over a decade. 442 44320181126: 444 On amd64, arm64 and armv7 (architectures that install LLVM's ld.lld 445 linker as /usr/bin/ld) GNU ld is no longer installed as ld.bfd, as 446 it produces broken binaries when ifuncs are in use. Users needing 447 GNU ld should install the binutils port or package. 448 44920181123: 450 The BSD crtbegin and crtend code has been enabled by default. It has 451 had extensive testing on amd64, arm64, and i386. It can be disabled 452 by building a world with -DWITHOUT_BSD_CRTBEGIN. 453 45420181115: 455 The set of CTM commands (ctm, ctm_smail, ctm_rmail, ctm_dequeue) 456 has been converted to a port (misc/ctm) and will be removed from 457 FreeBSD-13. It is available as a package (ctm) for all supported 458 FreeBSD versions. 459 46020181110: 461 The default newsyslog.conf(5) file has been changed to only include 462 files in /etc/newsyslog.conf.d/ and /usr/local/etc/newsyslog.conf.d/ if 463 the filenames end in '.conf' and do not begin with a '.'. 464 465 You should check the configuration files in these two directories match 466 this naming convention. You can verify which configuration files are 467 being included using the command: 468 $ newsyslog -Nrv 469 47020181015: 471 Ports for the DRM modules have been simplified. Now, amd64 users should 472 just install the drm-kmod port. All others should install 473 drm-legacy-kmod. 474 475 Graphics hardware that's newer than about 2010 usually works with 476 drm-kmod. For hardware older than 2013, however, some users will need 477 to use drm-legacy-kmod if drm-kmod doesn't work for them. Hardware older 478 than 2008 usually only works in drm-legacy-kmod. The graphics team can 479 only commit to hardware made since 2013 due to the complexity of the 480 market and difficulty to test all the older cards effectively. If you 481 have hardware supported by drm-kmod, you are strongly encouraged to use 482 that as you will get better support. 483 484 Other than KPI chasing, drm-legacy-kmod will not be updated. As outlined 485 elsewhere, the drm and drm2 modules will be eliminated from the src base 486 soon (with a limited exception for arm). Please update to the package 487 asap and report any issues to x11@freebsd.org. 488 489 Generally, anybody using the drm*-kmod packages should add 490 WITHOUT_DRM_MODULE=t and WITHOUT_DRM2_MODULE=t to avoid nasty 491 cross-threading surprises, especially with automatic driver 492 loading from X11 startup. These will become the defaults in 13-current 493 shortly. 494 49520181012: 496 The ixlv(4) driver has been renamed to iavf(4). As a consequence, 497 custom kernel and module loading configuration files must be updated 498 accordingly. Moreover, interfaces previous presented as ixlvN to the 499 system are now exposed as iavfN and network configuration files must 500 be adjusted as necessary. 501 50220181009: 503 OpenSSL has been updated to version 1.1.1. This update included 504 additional various API changes throughout the base system. It is 505 important to rebuild third-party software after upgrading. The value 506 of __FreeBSD_version has been bumped accordingly. 507 50820181006: 509 The legacy DRM modules and drivers have now been added to the loader's 510 module blacklist, in favor of loading them with kld_list in rc.conf(5). 511 The module blacklist may be overridden with the loader.conf(5) 512 'module_blacklist' variable, but loading them via rc.conf(5) is strongly 513 encouraged. 514 51520181002: 516 The cam(4) based nda(4) driver will be used over nvd(4) by default on 517 powerpc64. You may set 'options NVME_USE_NVD=1' in your kernel conf or 518 loader tunable 'hw.nvme.use_nvd=1' if you wish to use the existing 519 driver. Make sure to edit /boot/etc/kboot.conf and fstab to use the 520 nda device name. 521 52220180913: 523 Reproducible build mode is now on by default, in preparation for 524 FreeBSD 12.0. This eliminates build metadata such as the user, 525 host, and time from the kernel (and uname), unless the working tree 526 corresponds to a modified checkout from a version control system. 527 The previous behavior can be obtained by setting the /etc/src.conf 528 knob WITHOUT_REPRODUCIBLE_BUILD. 529 53020180826: 531 The Yarrow CSPRNG has been removed from the kernel as it has not been 532 supported by its designers since at least 2003. Fortuna has been the 533 default since FreeBSD-11. 534 53520180822: 536 devctl freeze/thaw have gone into the tree, the rc scripts have been 537 updated to use them and devmatch has been changed. You should update 538 kernel, userland and rc scripts all at the same time. 539 54020180818: 541 The default interpreter has been switched from 4th to Lua. 542 LOADER_DEFAULT_INTERP, documented in build(7), will override the default 543 interpreter. If you have custom FORTH code you will need to set 544 LOADER_DEFAULT_INTERP=4th (valid values are 4th, lua or simp) in 545 src.conf for the build. This will create default hard links between 546 loader and loader_4th instead of loader and loader_lua, the new default. 547 If you are using UEFI it will create the proper hard link to loader.efi. 548 549 bhyve uses userboot.so. It remains 4th-only until some issues are solved 550 regarding coexisting with multiple versions of FreeBSD are resolved. 551 55220180815: 553 ls(1) now respects the COLORTERM environment variable used in other 554 systems and software to indicate that a colored terminal is both 555 supported and desired. If ls(1) is suddenly emitting colors, they may 556 be disabled again by either removing the unwanted COLORTERM from your 557 environment, or using `ls --color=never`. The ls(1) specific CLICOLOR 558 may not be observed in a future release. 559 56020180808: 561 The default pager for most commands has been changed to "less". To 562 restore the old behavior, set PAGER="more" and MANPAGER="more -s" in 563 your environment. 564 56520180731: 566 The jedec_ts(4) driver has been removed. A superset of its functionality 567 is available in the jedec_dimm(4) driver, and the manpage for that 568 driver includes migration instructions. If you have "device jedec_ts" 569 in your kernel configuration file, it must be removed. 570 57120180730: 572 amd64/GENERIC now has EFI runtime services, EFIRT, enabled by default. 573 This should have no effect if the kernel is booted via BIOS/legacy boot. 574 EFIRT may be disabled via a loader tunable, efi.rt.disabled, if a system 575 has a buggy firmware that prevents a successful boot due to use of 576 runtime services. 577 57820180727: 579 Atmel AT91RM9200 and AT91SAM9, Cavium CNS 11xx and XScale 580 support has been removed from the tree. These ports were 581 obsolete and/or known to be broken for many years. 582 58320180723: 584 loader.efi has been augmented to participate more fully in the 585 UEFI boot manager protocol. loader.efi will now look at the 586 BootXXXX environment variable to determine if a specific kernel 587 or root partition was specified. XXXX is derived from BootCurrent. 588 efibootmgr(8) manages these standard UEFI variables. 589 59020180720: 591 zfsloader's functionality has now been folded into loader. 592 zfsloader is no longer necessary once you've updated your 593 boot blocks. For a transition period, we will install a 594 hardlink for zfsloader to loader to allow a smooth transition 595 until the boot blocks can be updated (hard link because old 596 zfs boot blocks don't understand symlinks). 597 59820180719: 599 ARM64 now have efifb support, if you want to have serial console 600 on your arm64 board when an screen is connected and the bootloader 601 setup a frame buffer for us to use, just add : 602 boot_serial=YES 603 boot_multicons=YES 604 in /boot/loader.conf 605 For Raspberry Pi 3 (RPI) users, this is needed even if you don't have 606 an screen connected as the firmware will setup a frame buffer are that 607 u-boot will expose as an EFI frame buffer. 608 60920180719: 610 New uid:gid added, ntpd:ntpd (123:123). Be sure to run mergemaster 611 or take steps to update /etc/passwd before doing installworld on 612 existing systems. Do not skip the "mergemaster -Fp" step before 613 installworld, as described in the update procedures near the bottom 614 of this document. Also, rc.d/ntpd now starts ntpd(8) as user ntpd 615 if the new mac_ntpd(4) policy is available, unless ntpd_flags or 616 the ntp config file contain options that change file/dir locations. 617 When such options (e.g., "statsdir" or "crypto") are used, ntpd can 618 still be run as non-root by setting ntpd_user=ntpd in rc.conf, after 619 taking steps to ensure that all required files/dirs are accessible 620 by the ntpd user. 621 62220180717: 623 Big endian arm support has been removed. 624 62520180711: 626 The static environment setup in kernel configs is no longer mutually 627 exclusive with the loader(8) environment by default. In order to 628 restore the previous default behavior of disabling the loader(8) 629 environment if a static environment is present, you must specify 630 loader_env.disabled=1 in the static environment. 631 63220180705: 633 The ABI of syscalls used by management tools like sockstat and 634 netstat has been broken to allow 32-bit binaries to work on 635 64-bit kernels without modification. These programs will need 636 to match the kernel in order to function. External programs may 637 require minor modifications to accommodate a change of type in 638 structures from pointers to 64-bit virtual addresses. 639 64020180702: 641 On i386 and amd64 atomics are now inlined. Out of tree modules using 642 atomics will need to be rebuilt. 643 64420180701: 645 The '%I' format in the kern.corefile sysctl limits the number of 646 core files that a process can generate to the number stored in the 647 debug.ncores sysctl. The '%I' format is replaced by the single digit 648 index. Previously, if all indexes were taken the kernel would overwrite 649 only a core file with the highest index in a filename. 650 Currently the system will create a new core file if there is a free 651 index or if all slots are taken it will overwrite the oldest one. 652 65320180630: 654 Clang, llvm, lld, lldb, compiler-rt and libc++ have been upgraded to 655 6.0.1. Please see the 20141231 entry below for information about 656 prerequisites and upgrading, if you are not already using clang 3.5.0 657 or higher. 658 65920180628: 660 r335753 introduced a new quoting method. However, etc/devd/devmatch.conf 661 needed to be changed to work with it. This change was made with r335763 662 and requires a mergemaster / etcupdate / etc to update the installed 663 file. 664 66520180612: 666 r334930 changed the interface between the NFS modules, so they all 667 need to be rebuilt. r335018 did a __FreeBSD_version bump for this. 668 66920180530: 670 As of r334391 lld is the default amd64 system linker; it is installed 671 as /usr/bin/ld. Kernel build workarounds (see 20180510 entry) are no 672 longer necessary. 673 67420180530: 675 The kernel / userland interface for devinfo changed, so you'll 676 need a new kernel and userland as a pair for it to work (rebuilding 677 lib/libdevinfo is all that's required). devinfo and devmatch will 678 not work, but everything else will when there's a mismatch. 679 68020180523: 681 The on-disk format for hwpmc callchain records has changed to include 682 threadid corresponding to a given record. This changes the field offsets 683 and thus requires that libpmcstat be rebuilt before using a kernel 684 later than r334108. 685 68620180517: 687 The vxge(4) driver has been removed. This driver was introduced into 688 HEAD one week before the Exar left the Ethernet market and is not 689 known to be used. If you have device vxge in your kernel config file 690 it must be removed. 691 69220180510: 693 The amd64 kernel now requires a ld that supports ifunc to produce a 694 working kernel, either lld or a newer binutils. lld is built by default 695 on amd64, and the 'buildkernel' target uses it automatically. However, 696 it is not the default linker, so building the kernel the traditional 697 way requires LD=ld.lld on the command line (or LD=/usr/local/bin/ld for 698 binutils port/package). lld will soon be default, and this requirement 699 will go away. 700 701 NOTE: As of r334391 lld is the default system linker on amd64, and no 702 workaround is necessary. 703 70420180508: 705 The nxge(4) driver has been removed. This driver was for PCI-X 10g 706 cards made by s2io/Neterion. The company was acquired by Exar and 707 no longer sells or supports Ethernet products. If you have device 708 nxge in your kernel config file it must be removed. 709 71020180504: 711 The tz database (tzdb) has been updated to 2018e. This version more 712 correctly models time stamps in time zones with negative DST such as 713 Europe/Dublin (from 1971 on), Europe/Prague (1946/7), and 714 Africa/Windhoek (1994/2017). This does not affect the UT offsets, only 715 time zone abbreviations and the tm_isdst flag. 716 71720180502: 718 The ixgb(4) driver has been removed. This driver was for an early and 719 uncommon legacy PCI 10GbE for a single ASIC, Intel 82597EX. Intel 720 quickly shifted to the long lived ixgbe family. If you have device 721 ixgb in your kernel config file it must be removed. 722 72320180501: 724 The lmc(4) driver has been removed. This was a WAN interface 725 card that was already reportedly rare in 2003, and had an ambiguous 726 license. If you have device lmc in your kernel config file it must 727 be removed. 728 72920180413: 730 Support for Arcnet networks has been removed. If you have device 731 arcnet or device cm in your kernel config file they must be 732 removed. 733 73420180411: 735 Support for FDDI networks has been removed. If you have device 736 fddi or device fpa in your kernel config file they must be 737 removed. 738 73920180406: 740 In addition to supporting RFC 3164 formatted messages, the 741 syslogd(8) service is now capable of parsing RFC 5424 formatted 742 log messages. The main benefit of using RFC 5424 is that clients 743 may now send log messages with timestamps containing year numbers, 744 microseconds and time zone offsets. 745 746 Similarly, the syslog(3) C library function has been altered to 747 send RFC 5424 formatted messages to the local system logging 748 daemon. On systems using syslogd(8), this change should have no 749 negative impact, as long as syslogd(8) and the C library are 750 updated at the same time. On systems using a different system 751 logging daemon, it may be necessary to make configuration 752 adjustments, depending on the software used. 753 754 When using syslog-ng, add the 'syslog-protocol' flag to local 755 input sources to enable parsing of RFC 5424 formatted messages: 756 757 source src { 758 unix-dgram("/var/run/log" flags(syslog-protocol)); 759 } 760 761 When using rsyslog, disable the 'SysSock.UseSpecialParser' option 762 of the 'imuxsock' module to let messages be processed by the 763 regular RFC 3164/5424 parsing pipeline: 764 765 module(load="imuxsock" SysSock.UseSpecialParser="off") 766 767 Do note that these changes only affect communication between local 768 applications and syslogd(8). The format that syslogd(8) uses to 769 store messages on disk or forward messages to other systems 770 remains unchanged. syslogd(8) still uses RFC 3164 for these 771 purposes. Options to customize this behaviour will be added in the 772 future. Utilities that process log files stored in /var/log are 773 thus expected to continue to function as before. 774 775 __FreeBSD_version has been incremented to 1200061 to denote this 776 change. 777 77820180328: 779 Support for token ring networks has been removed. If you 780 have "device token" in your kernel config you should remove 781 it. No device drivers supported token ring. 782 78320180323: 784 makefs was modified to be able to tag ISO9660 El Torito boot catalog 785 entries as EFI instead of overloading the i386 tag as done previously. 786 The amd64 mkisoimages.sh script used to build amd64 ISO images for 787 release was updated to use this. This may mean that makefs must be 788 updated before "make cdrom" can be run in the release directory. This 789 should be as simple as: 790 791 $ cd $SRCDIR/usr.sbin/makefs 792 $ make depend all install 793 79420180212: 795 FreeBSD boot loader enhanced with Lua scripting. It's purely opt-in for 796 now by building WITH_LOADER_LUA and WITHOUT_FORTH in /etc/src.conf. 797 Co-existence for the transition period will come shortly. Booting is a 798 complex environment and test coverage for Lua-enabled loaders has been 799 thin, so it would be prudent to assume it might not work and make 800 provisions for backup boot methods. 801 80220180211: 803 devmatch functionality has been turned on in devd. It will automatically 804 load drivers for unattached devices. This may cause unexpected drivers 805 to be loaded. Please report any problems to current@ and 806 imp@freebsd.org. 807 80820180114: 809 Clang, llvm, lld, lldb, compiler-rt and libc++ have been upgraded to 810 6.0.0. Please see the 20141231 entry below for information about 811 prerequisites and upgrading, if you are not already using clang 3.5.0 812 or higher. 813 81420180110: 815 LLVM's lld linker is now used as the FreeBSD/amd64 bootstrap linker. 816 This means it is used to link the kernel and userland libraries and 817 executables, but is not yet installed as /usr/bin/ld by default. 818 819 To revert to ld.bfd as the bootstrap linker, in /etc/src.conf set 820 WITHOUT_LLD_BOOTSTRAP=yes 821 82220180110: 823 On i386, pmtimer has been removed. Its functionality has been folded 824 into apm. It was a no-op on ACPI in current for a while now (but was 825 still needed on i386 in FreeBSD 11 and earlier). Users may need to 826 remove it from kernel config files. 827 82820180104: 829 The use of RSS hash from the network card aka flowid has been 830 disabled by default for lagg(4) as it's currently incompatible with 831 the lacp and loadbalance protocols. 832 833 This can be re-enabled by setting the following in loader.conf: 834 net.link.lagg.default_use_flowid="1" 835 83620180102: 837 The SW_WATCHDOG option is no longer necessary to enable the 838 hardclock-based software watchdog if no hardware watchdog is 839 configured. As before, SW_WATCHDOG will cause the software 840 watchdog to be enabled even if a hardware watchdog is configured. 841 84220171215: 843 r326887 fixes the issue described in the 20171214 UPDATING entry. 844 r326888 flips the switch back to building GELI support always. 845 84620171214: 847 r362593 broke ZFS + GELI support for reasons unknown. However, 848 it also broke ZFS support generally, so GELI has been turned off 849 by default as the lesser evil in r326857. If you boot off ZFS and/or 850 GELI, it might not be a good time to update. 851 85220171125: 853 PowerPC users must update loader(8) by rebuilding world before 854 installing a new kernel, as the protocol connecting them has 855 changed. Without the update, loader metadata will not be passed 856 successfully to the kernel and users will have to enter their 857 root partition at the kernel mountroot prompt to continue booting. 858 Newer versions of loader can boot old kernels without issue. 859 86020171110: 861 The LOADER_FIREWIRE_SUPPORT build variable as been renamed to 862 WITH/OUT_LOADER_FIREWIRE. LOADER_{NO_,}GELI_SUPPORT has been renamed 863 to WITH/OUT_LOADER_GELI. 864 86520171106: 866 The naive and non-compliant support of posix_fallocate(2) in ZFS 867 has been removed as of r325320. The system call now returns EINVAL 868 when used on a ZFS file. Although the new behavior complies with the 869 standard, some consumers are not prepared to cope with it. 870 One known victim is lld prior to r325420. 871 87220171102: 873 Building in a FreeBSD src checkout will automatically create object 874 directories now rather than store files in the current directory if 875 'make obj' was not ran. Calling 'make obj' is no longer necessary. 876 This feature can be disabled by setting WITHOUT_AUTO_OBJ=yes in 877 /etc/src-env.conf (not /etc/src.conf), or passing the option in the 878 environment. 879 88020171101: 881 The default MAKEOBJDIR has changed from /usr/obj/<srcdir> for native 882 builds, and /usr/obj/<arch>/<srcdir> for cross-builds, to a unified 883 /usr/obj/<srcdir>/<arch>. This behavior can be changed to the old 884 format by setting WITHOUT_UNIFIED_OBJDIR=yes in /etc/src-env.conf, 885 the environment, or with -DWITHOUT_UNIFIED_OBJDIR when building. 886 The UNIFIED_OBJDIR option is a transitional feature that will be 887 removed for 12.0 release; please migrate to the new format for any 888 tools by looking up the OBJDIR used by 'make -V .OBJDIR' means rather 889 than hardcoding paths. 890 89120171028: 892 The native-xtools target no longer installs the files by default to the 893 OBJDIR. Use the native-xtools-install target with a DESTDIR to install 894 to ${DESTDIR}/${NXTP} where NXTP defaults to /nxb-bin. 895 89620171021: 897 As part of the boot loader infrastructure cleanup, LOADER_*_SUPPORT 898 options are changing from controlling the build if defined / undefined 899 to controlling the build with explicit 'yes' or 'no' values. They will 900 shift to WITH/WITHOUT options to match other options in the system. 901 90220171010: 903 libstand has turned into a private library for sys/boot use only. 904 It is no longer supported as a public interface outside of sys/boot. 905 90620171005: 907 The arm port has split armv6 into armv6 and armv7. armv7 is now 908 a valid TARGET_ARCH/MACHINE_ARCH setting. If you have an armv7 system 909 and are running a kernel from before r324363, you will need to add 910 MACHINE_ARCH=armv7 to 'make buildworld' to do a native build. 911 91220171003: 913 When building multiple kernels using KERNCONF, non-existent KERNCONF 914 files will produce an error and buildkernel will fail. Previously 915 missing KERNCONF files silently failed giving no indication as to 916 why, only to subsequently discover during installkernel that the 917 desired kernel was never built in the first place. 918 91920170912: 920 The default serial number format for CTL LUNs has changed. This will 921 affect users who use /dev/diskid/* device nodes, or whose FibreChannel 922 or iSCSI clients care about their LUNs' serial numbers. Users who 923 require serial number stability should hardcode serial numbers in 924 /etc/ctl.conf . 925 92620170912: 927 For 32-bit arm compiled for hard-float support, soft-floating point 928 binaries now always get their shared libraries from 929 LD_SOFT_LIBRARY_PATH (in the past, this was only used if 930 /usr/libsoft also existed). Only users with a hard-float ld.so, but 931 soft-float everything else should be affected. 932 93320170826: 934 The geli password typed at boot is now hidden. To restore the previous 935 behavior, see geli(8) for configuration options. 936 93720170825: 938 Move PMTUD blackhole counters to TCPSTATS and remove them from bare 939 sysctl values. Minor nit, but requires a rebuild of both world/kernel 940 to complete. 941 94220170814: 943 "make check" behavior (made in ^/head@r295380) has been changed to 944 execute from a limited sandbox, as opposed to executing from 945 ${TESTSDIR}. 946 947 Behavioral changes: 948 - The "beforecheck" and "aftercheck" targets are now specified. 949 - ${CHECKDIR} (added in commit noted above) has been removed. 950 - Legacy behavior can be enabled by setting 951 WITHOUT_MAKE_CHECK_USE_SANDBOX in src.conf(5) or the environment. 952 953 If the limited sandbox mode is enabled, "make check" will execute 954 "make distribution", then install, execute the tests, and clean up the 955 sandbox if successful. 956 957 The "make distribution" and "make install" targets are typically run as 958 root to set appropriate permissions and ownership at installation time. 959 The end-user should set "WITH_INSTALL_AS_USER" in src.conf(5) or the 960 environment if executing "make check" with limited sandbox mode using 961 an unprivileged user. 962 96320170808: 964 Since the switch to GPT disk labels, fsck for UFS/FFS has been 965 unable to automatically find alternate superblocks. As of r322297, 966 the information needed to find alternate superblocks has been 967 moved to the end of the area reserved for the boot block. 968 Filesystems created with a newfs of this vintage or later 969 will create the recovery information. If you have a filesystem 970 created prior to this change and wish to have a recovery block 971 created for your filesystem, you can do so by running fsck in 972 foreground mode (i.e., do not use the -p or -y options). As it 973 starts, fsck will ask ``SAVE DATA TO FIND ALTERNATE SUPERBLOCKS'' 974 to which you should answer yes. 975 97620170728: 977 As of r321665, an NFSv4 server configuration that services 978 Kerberos mounts or clients that do not support the uid/gid in 979 owner/owner_group string capability, must explicitly enable 980 the nfsuserd daemon by adding nfsuserd_enable="YES" to the 981 machine's /etc/rc.conf file. 982 98320170722: 984 Clang, llvm, lldb, compiler-rt and libc++ have been upgraded to 5.0.0. 985 Please see the 20141231 entry below for information about prerequisites 986 and upgrading, if you are not already using clang 3.5.0 or higher. 987 98820170701: 989 WITHOUT_RCMDS is now the default. Set WITH_RCMDS if you need the 990 r-commands (rlogin, rsh, etc.) to be built with the base system. 991 99220170625: 993 The FreeBSD/powerpc platform now uses a 64-bit type for time_t. This is 994 a very major ABI incompatible change, so users of FreeBSD/powerpc must 995 be careful when performing source upgrades. It is best to run 996 'make installworld' from an alternate root system, either a live 997 CD/memory stick, or a temporary root partition. Additionally, all ports 998 must be recompiled. powerpc64 is largely unaffected, except in the case 999 of 32-bit compatibility. All 32-bit binaries will be affected. 1000 100120170623: 1002 Forward compatibility for the "ino64" project have been committed. This 1003 will allow most new binaries to run on older kernels in a limited 1004 fashion. This prevents many of the common foot-shooting actions in the 1005 upgrade as well as the limited ability to roll back the kernel across 1006 the ino64 upgrade. Complicated use cases may not work properly, though 1007 enough simpler ones work to allow recovery in most situations. 1008 100920170620: 1010 Switch back to the BSDL dtc (Device Tree Compiler). Set WITH_GPL_DTC 1011 if you require the GPL compiler. 1012 101320170618: 1014 The internal ABI used for communication between the NFS kernel modules 1015 was changed by r320085, so __FreeBSD_version was bumped to 1016 ensure all the NFS related modules are updated together. 1017 101820170617: 1019 The ABI of struct event was changed by extending the data 1020 member to 64bit and adding ext fields. For upgrade, same 1021 precautions as for the entry 20170523 "ino64" must be 1022 followed. 1023 102420170531: 1025 The GNU roff toolchain has been removed from base. To render manpages 1026 which are not supported by mandoc(1), man(1) can fallback on GNU roff 1027 from ports (and recommends to install it). 1028 To render roff(7) documents, consider using GNU roff from ports or the 1029 heirloom doctools roff toolchain from ports via pkg install groff or 1030 via pkg install heirloom-doctools. 1031 103220170524: 1033 The ath(4) and ath_hal(4) modules now build piecemeal to allow for 1034 smaller runtime footprint builds. This is useful for embedded systems 1035 which only require one chipset support. 1036 1037 If you load it as a module, make sure this is in /boot/loader.conf: 1038 1039 if_ath_load="YES" 1040 1041 This will load the HAL, all chip/RF backends and if_ath_pci. 1042 If you have if_ath_pci in /boot/loader.conf, ensure it is after 1043 if_ath or it will not load any HAL chipset support. 1044 1045 If you want to selectively load things (eg on ye cheape ARM/MIPS 1046 platforms where RAM is at a premium) you should: 1047 1048 * load ath_hal 1049 * load the chip modules in question 1050 * load ath_rate, ath_dfs 1051 * load ath_main 1052 * load if_ath_pci and/or if_ath_ahb depending upon your particular 1053 bus bind type - this is where probe/attach is done. 1054 1055 For further comments/feedback, poke adrian@ . 1056 105720170523: 1058 The "ino64" 64-bit inode project has been committed, which extends 1059 a number of types to 64 bits. Upgrading in place requires care and 1060 adherence to the documented upgrade procedure. 1061 1062 If using a custom kernel configuration ensure that the 1063 COMPAT_FREEBSD11 option is included (as during the upgrade the 1064 system will be running the ino64 kernel with the existing world). 1065 1066 For the safest in-place upgrade begin by removing previous build 1067 artifacts via "rm -rf /usr/obj/*". Then, carefully follow the full 1068 procedure documented below under the heading "To rebuild everything and 1069 install it on the current system." Specifically, a reboot is required 1070 after installing the new kernel before installing world. While an 1071 installworld normally works by accident from multiuser after rebooting 1072 the proper kernel, there are many cases where this will fail across this 1073 upgrade and installworld from single user is required. 1074 107520170424: 1076 The NATM framework including the en(4), fatm(4), hatm(4), and 1077 patm(4) devices has been removed. Consumers should plan a 1078 migration before the end-of-life date for FreeBSD 11. 1079 108020170420: 1081 GNU diff has been replaced by a BSD licensed diff. Some features of GNU 1082 diff has not been implemented, if those are needed a newer version of 1083 GNU diff is available via the diffutils package under the gdiff name. 1084 108520170413: 1086 As of r316810 for ipfilter, keep frags is no longer assumed when 1087 keep state is specified in a rule. r316810 aligns ipfilter with 1088 documentation in man pages separating keep frags from keep state. 1089 This allows keep state to be specified without forcing keep frags 1090 and allows keep frags to be specified independently of keep state. 1091 To maintain previous behaviour, also specify keep frags with 1092 keep state (as documented in ipf.conf.5). 1093 109420170407: 1095 arm64 builds now use the base system LLD 4.0.0 linker by default, 1096 instead of requiring that the aarch64-binutils port or package be 1097 installed. To continue using aarch64-binutils, set 1098 CROSS_BINUTILS_PREFIX=/usr/local/aarch64-freebsd/bin . 1099 110020170405: 1101 The UDP optimization in entry 20160818 that added the sysctl 1102 net.inet.udp.require_l2_bcast has been reverted. L2 broadcast 1103 packets will no longer be treated as L3 broadcast packets. 1104 110520170331: 1106 Binds and sends to the loopback addresses, IPv6 and IPv4, will now 1107 use any explicitly assigned loopback address available in the jail 1108 instead of using the first assigned address of the jail. 1109 111020170329: 1111 The ctl.ko module no longer implements the iSCSI target frontend: 1112 cfiscsi.ko does instead. 1113 1114 If building cfiscsi.ko as a kernel module, the module can be loaded 1115 via one of the following methods: 1116 - `cfiscsi_load="YES"` in loader.conf(5). 1117 - Add `cfiscsi` to `$kld_list` in rc.conf(5). 1118 - ctladm(8)/ctld(8), when compiled with iSCSI support 1119 (`WITH_ISCSI=yes` in src.conf(5)) 1120 1121 Please see cfiscsi(4) for more details. 1122 112320170316: 1124 The mmcsd.ko module now additionally depends on geom_flashmap.ko. 1125 Also, mmc.ko and mmcsd.ko need to be a matching pair built from the 1126 same source (previously, the dependency of mmcsd.ko on mmc.ko was 1127 missing, but mmcsd.ko now will refuse to load if it is incompatible 1128 with mmc.ko). 1129 113020170315: 1131 The syntax of ipfw(8) named states was changed to avoid ambiguity. 1132 If you have used named states in the firewall rules, you need to modify 1133 them after installworld and before rebooting. Now named states must 1134 be prefixed with colon. 1135 113620170311: 1137 The old drm (sys/dev/drm/) drivers for i915 and radeon have been 1138 removed as the userland we provide cannot use them. The KMS version 1139 (sys/dev/drm2) supports the same hardware. 1140 114120170302: 1142 Clang, llvm, lldb, compiler-rt and libc++ have been upgraded to 4.0.0. 1143 Please see the 20141231 entry below for information about prerequisites 1144 and upgrading, if you are not already using clang 3.5.0 or higher. 1145 114620170221: 1147 The code that provides support for ZFS .zfs/ directory functionality 1148 has been reimplemented. It's not possible now to create a snapshot 1149 by mkdir under .zfs/snapshot/. That should be the only user visible 1150 change. 1151 115220170216: 1153 EISA bus support has been removed. The WITH_EISA option is no longer 1154 valid. 1155 115620170215: 1157 MCA bus support has been removed. 1158 115920170127: 1160 The WITH_LLD_AS_LD / WITHOUT_LLD_AS_LD build knobs have been renamed 1161 WITH_LLD_IS_LD / WITHOUT_LLD_IS_LD, for consistency with CLANG_IS_CC. 1162 116320170112: 1164 The EM_MULTIQUEUE kernel configuration option is deprecated now that 1165 the em(4) driver conforms to iflib specifications. 1166 116720170109: 1168 The igb(4), em(4) and lem(4) ethernet drivers are now implemented via 1169 IFLIB. If you have a custom kernel configuration that excludes em(4) 1170 but you use igb(4), you need to re-add em(4) to your custom 1171 configuration. 1172 117320161217: 1174 Clang, llvm, lldb, compiler-rt and libc++ have been upgraded to 3.9.1. 1175 Please see the 20141231 entry below for information about prerequisites 1176 and upgrading, if you are not already using clang 3.5.0 or higher. 1177 117820161124: 1179 Clang, llvm, lldb, compiler-rt and libc++ have been upgraded to 3.9.0. 1180 Please see the 20141231 entry below for information about prerequisites 1181 and upgrading, if you are not already using clang 3.5.0 or higher. 1182 118320161119: 1184 The layout of the pmap structure has changed for powerpc to put the pmap 1185 statistics at the front for all CPU variations. libkvm(3) and all tools 1186 that link against it need to be recompiled. 1187 118820161030: 1189 isl(4) and cyapa(4) drivers now require a new driver, 1190 chromebook_platform(4), to work properly on Chromebook-class hardware. 1191 On other types of hardware the drivers may need to be configured using 1192 device hints. Please see the corresponding manual pages for details. 1193 119420161017: 1195 The urtwn(4) driver was merged into rtwn(4) and now consists of 1196 rtwn(4) main module + rtwn_usb(4) and rtwn_pci(4) bus-specific 1197 parts. 1198 Also, firmware for RTL8188CE was renamed due to possible name 1199 conflict (rtwnrtl8192cU(B) -> rtwnrtl8192cE(B)) 1200 120120161015: 1202 GNU rcs has been removed from base. It is available as packages: 1203 - rcs: Latest GPLv3 GNU rcs version. 1204 - rcs57: Copy of the latest version of GNU rcs (GPLv2) before it was 1205 removed from base. 1206 120720161008: 1208 Use of the cc_cdg, cc_chd, cc_hd, or cc_vegas congestion control 1209 modules now requires that the kernel configuration contain the 1210 TCP_HHOOK option. (This option is included in the GENERIC kernel.) 1211 121220161003: 1213 The WITHOUT_ELFCOPY_AS_OBJCOPY src.conf(5) knob has been retired. 1214 ELF Tool Chain's elfcopy is always installed as /usr/bin/objcopy. 1215 121620160924: 1217 Relocatable object files with the extension of .So have been renamed 1218 to use an extension of .pico instead. The purpose of this change is 1219 to avoid a name clash with shared libraries on case-insensitive file 1220 systems. On those file systems, foo.So is the same file as foo.so. 1221 122220160918: 1223 GNU rcs has been turned off by default. It can (temporarily) be built 1224 again by adding WITH_RCS knob in src.conf. 1225 Otherwise, GNU rcs is available from packages: 1226 - rcs: Latest GPLv3 GNU rcs version. 1227 - rcs57: Copy of the latest version of GNU rcs (GPLv2) from base. 1228 122920160918: 1230 The backup_uses_rcs functionality has been removed from rc.subr. 1231 123220160908: 1233 The queue(3) debugging macro, QUEUE_MACRO_DEBUG, has been split into 1234 two separate components, QUEUE_MACRO_DEBUG_TRACE and 1235 QUEUE_MACRO_DEBUG_TRASH. Define both for the original 1236 QUEUE_MACRO_DEBUG behavior. 1237 123820160824: 1239 r304787 changed some ioctl interfaces between the iSCSI userspace 1240 programs and the kernel. ctladm, ctld, iscsictl, and iscsid must be 1241 rebuilt to work with new kernels. __FreeBSD_version has been bumped 1242 to 1200005. 1243 124420160818: 1245 The UDP receive code has been updated to only treat incoming UDP 1246 packets that were addressed to an L2 broadcast address as L3 1247 broadcast packets. It is not expected that this will affect any 1248 standards-conforming UDP application. The new behaviour can be 1249 disabled by setting the sysctl net.inet.udp.require_l2_bcast to 1250 0. 1251 125220160818: 1253 Remove the openbsd_poll system call. 1254 __FreeBSD_version has been bumped because of this. 1255 125620160708: 1257 The stable/11 branch has been created from head@r302406. 1258 125920160622: 1260 The libc stub for the pipe(2) system call has been replaced with 1261 a wrapper that calls the pipe2(2) system call and the pipe(2) 1262 system call is now only implemented by the kernels that include 1263 "options COMPAT_FREEBSD10" in their config file (this is the 1264 default). Users should ensure that this option is enabled in 1265 their kernel or upgrade userspace to r302092 before upgrading their 1266 kernel. 1267 126820160527: 1269 CAM will now strip leading spaces from SCSI disks' serial numbers. 1270 This will affect users who create UFS filesystems on SCSI disks using 1271 those disk's diskid device nodes. For example, if /etc/fstab 1272 previously contained a line like 1273 "/dev/diskid/DISK-%20%20%20%20%20%20%20ABCDEFG0123456", you should 1274 change it to "/dev/diskid/DISK-ABCDEFG0123456". Users of geom 1275 transforms like gmirror may also be affected. ZFS users should 1276 generally be fine. 1277 127820160523: 1279 The bitstring(3) API has been updated with new functionality and 1280 improved performance. But it is binary-incompatible with the old API. 1281 Objects built with the new headers may not be linked against objects 1282 built with the old headers. 1283 128420160520: 1285 The brk and sbrk functions have been removed from libc on arm64. 1286 Binutils from ports has been updated to not link to these 1287 functions and should be updated to the latest version before 1288 installing a new libc. 1289 129020160517: 1291 The armv6 port now defaults to hard float ABI. Limited support 1292 for running both hardfloat and soft float on the same system 1293 is available using the libraries installed with -DWITH_LIBSOFT. 1294 This has only been tested as an upgrade path for installworld 1295 and packages may fail or need manual intervention to run. New 1296 packages will be needed. 1297 1298 To update an existing self-hosted armv6hf system, you must add 1299 TARGET_ARCH=armv6 on the make command line for both the build 1300 and the install steps. 1301 130220160510: 1303 Kernel modules compiled outside of a kernel build now default to 1304 installing to /boot/modules instead of /boot/kernel. Many kernel 1305 modules built this way (such as those in ports) already overrode 1306 KMODDIR explicitly to install into /boot/modules. However, 1307 manually building and installing a module from /sys/modules will 1308 now install to /boot/modules instead of /boot/kernel. 1309 131020160414: 1311 The CAM I/O scheduler has been committed to the kernel. There should be 1312 no user visible impact. This does enable NCQ Trim on ada SSDs. While the 1313 list of known rogues that claim support for this but actually corrupt 1314 data is believed to be complete, be on the lookout for data 1315 corruption. The known rogue list is believed to be complete: 1316 1317 o Crucial MX100, M550 drives with MU01 firmware. 1318 o Micron M510 and M550 drives with MU01 firmware. 1319 o Micron M500 prior to MU07 firmware 1320 o Samsung 830, 840, and 850 all firmwares 1321 o FCCT M500 all firmwares 1322 1323 Crucial has firmware http://www.crucial.com/usa/en/support-ssd-firmware 1324 with working NCQ TRIM. For Micron branded drives, see your sales rep for 1325 updated firmware. Black listed drives will work correctly because these 1326 drives work correctly so long as no NCQ TRIMs are sent to them. Given 1327 this list is the same as found in Linux, it's believed there are no 1328 other rogues in the market place. All other models from the above 1329 vendors work. 1330 1331 To be safe, if you are at all concerned, you can quirk each of your 1332 drives to prevent NCQ from being sent by setting: 1333 kern.cam.ada.X.quirks="0x2" 1334 in loader.conf. If the drive requires the 4k sector quirk, set the 1335 quirks entry to 0x3. 1336 133720160330: 1338 The FAST_DEPEND build option has been removed and its functionality is 1339 now the one true way. The old mkdep(1) style of 'make depend' has 1340 been removed. See 20160311 for further details. 1341 134220160317: 1343 Resource range types have grown from unsigned long to uintmax_t. All 1344 drivers, and anything using libdevinfo, need to be recompiled. 1345 134620160311: 1347 WITH_FAST_DEPEND is now enabled by default for in-tree and out-of-tree 1348 builds. It no longer runs mkdep(1) during 'make depend', and the 1349 'make depend' stage can safely be skipped now as it is auto ran 1350 when building 'make all' and will generate all SRCS and DPSRCS before 1351 building anything else. Dependencies are gathered at compile time with 1352 -MF flags kept in separate .depend files per object file. Users should 1353 run 'make cleandepend' once if using -DNO_CLEAN to clean out older 1354 stale .depend files. 1355 135620160306: 1357 On amd64, clang 3.8.0 can now insert sections of type AMD64_UNWIND into 1358 kernel modules. Therefore, if you load any kernel modules at boot time, 1359 please install the boot loaders after you install the kernel, but before 1360 rebooting, e.g.: 1361 1362 make buildworld 1363 make buildkernel KERNCONF=YOUR_KERNEL_HERE 1364 make installkernel KERNCONF=YOUR_KERNEL_HERE 1365 make -C sys/boot install 1366 <reboot in single user> 1367 1368 Then follow the usual steps, described in the General Notes section, 1369 below. 1370 137120160305: 1372 Clang, llvm, lldb and compiler-rt have been upgraded to 3.8.0. Please 1373 see the 20141231 entry below for information about prerequisites and 1374 upgrading, if you are not already using clang 3.5.0 or higher. 1375 137620160301: 1377 The AIO subsystem is now a standard part of the kernel. The 1378 VFS_AIO kernel option and aio.ko kernel module have been removed. 1379 Due to stability concerns, asynchronous I/O requests are only 1380 permitted on sockets and raw disks by default. To enable 1381 asynchronous I/O requests on all file types, set the 1382 vfs.aio.enable_unsafe sysctl to a non-zero value. 1383 138420160226: 1385 The ELF object manipulation tool objcopy is now provided by the 1386 ELF Tool Chain project rather than by GNU binutils. It should be a 1387 drop-in replacement, with the addition of arm64 support. The 1388 (temporary) src.conf knob WITHOUT_ELFCOPY_AS_OBJCOPY knob may be set 1389 to obtain the GNU version if necessary. 1390 139120160129: 1392 Building ZFS pools on top of zvols is prohibited by default. That 1393 feature has never worked safely; it's always been prone to deadlocks. 1394 Using a zvol as the backing store for a VM guest's virtual disk will 1395 still work, even if the guest is using ZFS. Legacy behavior can be 1396 restored by setting vfs.zfs.vol.recursive=1. 1397 139820160119: 1399 The NONE and HPN patches has been removed from OpenSSH. They are 1400 still available in the security/openssh-portable port. 1401 140220160113: 1403 With the addition of ypldap(8), a new _ypldap user is now required 1404 during installworld. "mergemaster -p" can be used to add the user 1405 prior to installworld, as documented in the handbook. 1406 140720151216: 1408 The tftp loader (pxeboot) now uses the option root-path directive. As a 1409 consequence it no longer looks for a pxeboot.4th file on the tftp 1410 server. Instead it uses the regular /boot infrastructure as with the 1411 other loaders. 1412 141320151211: 1414 The code to start recording plug and play data into the modules has 1415 been committed. While the old tools will properly build a new kernel, 1416 a number of warnings about "unknown metadata record 4" will be produced 1417 for an older kldxref. To avoid such warnings, make sure to rebuild 1418 the kernel toolchain (or world). Make sure that you have r292078 or 1419 later when trying to build 292077 or later before rebuilding. 1420 142120151207: 1422 Debug data files are now built by default with 'make buildworld' and 1423 installed with 'make installworld'. This facilitates debugging but 1424 requires more disk space both during the build and for the installed 1425 world. Debug files may be disabled by setting WITHOUT_DEBUG_FILES=yes 1426 in src.conf(5). 1427 142820151130: 1429 r291527 changed the internal interface between the nfsd.ko and 1430 nfscommon.ko modules. As such, they must both be upgraded to-gether. 1431 __FreeBSD_version has been bumped because of this. 1432 143320151108: 1434 Add support for unicode collation strings leads to a change of 1435 order of files listed by ls(1) for example. To get back to the old 1436 behaviour, set LC_COLLATE environment variable to "C". 1437 1438 Databases administrators will need to reindex their databases given 1439 collation results will be different. 1440 1441 Due to a bug in install(1) it is recommended to remove the ancient 1442 locales before running make installworld. 1443 1444 rm -rf /usr/share/locale/* 1445 144620151030: 1447 The OpenSSL has been upgraded to 1.0.2d. Any binaries requiring 1448 libcrypto.so.7 or libssl.so.7 must be recompiled. 1449 145020151020: 1451 Qlogic 24xx/25xx firmware images were updated from 5.5.0 to 7.3.0. 1452 Kernel modules isp_2400_multi and isp_2500_multi were removed and 1453 should be replaced with isp_2400 and isp_2500 modules respectively. 1454 145520151017: 1456 The build previously allowed using 'make -n' to not recurse into 1457 sub-directories while showing what commands would be executed, and 1458 'make -n -n' to recursively show commands. Now 'make -n' will recurse 1459 and 'make -N' will not. 1460 146120151012: 1462 If you specify SENDMAIL_MC or SENDMAIL_CF in make.conf, mergemaster 1463 and etcupdate will now use this file. A custom sendmail.cf is now 1464 updated via this mechanism rather than via installworld. If you had 1465 excluded sendmail.cf in mergemaster.rc or etcupdate.conf, you may 1466 want to remove the exclusion or change it to "always install". 1467 /etc/mail/sendmail.cf is now managed the same way regardless of 1468 whether SENDMAIL_MC/SENDMAIL_CF is used. If you are not using 1469 SENDMAIL_MC/SENDMAIL_CF there should be no change in behavior. 1470 147120151011: 1472 Compatibility shims for legacy ATA device names have been removed. 1473 It includes ATA_STATIC_ID kernel option, kern.cam.ada.legacy_aliases 1474 and kern.geom.raid.legacy_aliases loader tunables, kern.devalias.* 1475 environment variables, /dev/ad* and /dev/ar* symbolic links. 1476 147720151006: 1478 Clang, llvm, lldb, compiler-rt and libc++ have been upgraded to 3.7.0. 1479 Please see the 20141231 entry below for information about prerequisites 1480 and upgrading, if you are not already using clang 3.5.0 or higher. 1481 148220150924: 1483 Kernel debug files have been moved to /usr/lib/debug/boot/kernel/, 1484 and renamed from .symbols to .debug. This reduces the size requirements 1485 on the boot partition or file system and provides consistency with 1486 userland debug files. 1487 1488 When using the supported kernel installation method the 1489 /usr/lib/debug/boot/kernel directory will be renamed (to kernel.old) 1490 as is done with /boot/kernel. 1491 1492 Developers wishing to maintain the historical behavior of installing 1493 debug files in /boot/kernel/ can set KERN_DEBUGDIR="" in src.conf(5). 1494 149520150827: 1496 The wireless drivers had undergone changes that remove the 'parent 1497 interface' from the ifconfig -l output. The rc.d network scripts 1498 used to check presence of a parent interface in the list, so old 1499 scripts would fail to start wireless networking. Thus, etcupdate(3) 1500 or mergemaster(8) run is required after kernel update, to update your 1501 rc.d scripts in /etc. 1502 150320150827: 1504 pf no longer supports 'scrub fragment crop' or 'scrub fragment drop-ovl' 1505 These configurations are now automatically interpreted as 1506 'scrub fragment reassemble'. 1507 150820150817: 1509 Kernel-loadable modules for the random(4) device are back. To use 1510 them, the kernel must have 1511 1512 device random 1513 options RANDOM_LOADABLE 1514 1515 kldload(8) can then be used to load random_fortuna.ko 1516 or random_yarrow.ko. Please note that due to the indirect 1517 function calls that the loadable modules need to provide, 1518 the build-in variants will be slightly more efficient. 1519 1520 The random(4) kernel option RANDOM_DUMMY has been retired due to 1521 unpopularity. It was not all that useful anyway. 1522 152320150813: 1524 The WITHOUT_ELFTOOLCHAIN_TOOLS src.conf(5) knob has been retired. 1525 Control over building the ELF Tool Chain tools is now provided by 1526 the WITHOUT_TOOLCHAIN knob. 1527 152820150810: 1529 The polarity of Pulse Per Second (PPS) capture events with the 1530 uart(4) driver has been corrected. Prior to this change the PPS 1531 "assert" event corresponded to the trailing edge of a positive PPS 1532 pulse and the "clear" event was the leading edge of the next pulse. 1533 1534 As the width of a PPS pulse in a typical GPS receiver is on the 1535 order of 1 millisecond, most users will not notice any significant 1536 difference with this change. 1537 1538 Anyone who has compensated for the historical polarity reversal by 1539 configuring a negative offset equal to the pulse width will need to 1540 remove that workaround. 1541 154220150809: 1543 The default group assigned to /dev/dri entries has been changed 1544 from 'wheel' to 'video' with the id of '44'. If you want to have 1545 access to the dri devices please add yourself to the video group 1546 with: 1547 1548 # pw groupmod video -m $USER 1549 155020150806: 1551 The menu.rc and loader.rc files will now be replaced during 1552 upgrades. Please migrate local changes to menu.rc.local and 1553 loader.rc.local instead. 1554 155520150805: 1556 GNU Binutils versions of addr2line, c++filt, nm, readelf, size, 1557 strings and strip have been removed. The src.conf(5) knob 1558 WITHOUT_ELFTOOLCHAIN_TOOLS no longer provides the binutils tools. 1559 156020150728: 1561 As ZFS requires more kernel stack pages than is the default on some 1562 architectures e.g. i386, it now warns if KSTACK_PAGES is less than 1563 ZFS_MIN_KSTACK_PAGES (which is 4 at the time of writing). 1564 1565 Please consider using 'options KSTACK_PAGES=X' where X is greater 1566 than or equal to ZFS_MIN_KSTACK_PAGES i.e. 4 in such configurations. 1567 156820150706: 1569 sendmail has been updated to 8.15.2. Starting with FreeBSD 11.0 1570 and sendmail 8.15, sendmail uses uncompressed IPv6 addresses by 1571 default, i.e., they will not contain "::". For example, instead 1572 of ::1, it will be 0:0:0:0:0:0:0:1. This permits a zero subnet 1573 to have a more specific match, such as different map entries for 1574 IPv6:0:0 vs IPv6:0. This change requires that configuration 1575 data (including maps, files, classes, custom ruleset, etc.) must 1576 use the same format, so make certain such configuration data is 1577 upgrading. As a very simple check search for patterns like 1578 'IPv6:[0-9a-fA-F:]*::' and 'IPv6::'. To return to the old 1579 behavior, set the m4 option confUSE_COMPRESSED_IPV6_ADDRESSES or 1580 the cf option UseCompressedIPv6Addresses. 1581 158220150630: 1583 The default kernel entropy-processing algorithm is now 1584 Fortuna, replacing Yarrow. 1585 1586 Assuming you have 'device random' in your kernel config 1587 file, the configurations allow a kernel option to override 1588 this default. You may choose *ONE* of: 1589 1590 options RANDOM_YARROW # Legacy /dev/random algorithm. 1591 options RANDOM_DUMMY # Blocking-only driver. 1592 1593 If you have neither, you get Fortuna. For most people, 1594 read no further, Fortuna will give a /dev/random that works 1595 like it always used to, and the difference will be irrelevant. 1596 1597 If you remove 'device random', you get *NO* kernel-processed 1598 entropy at all. This may be acceptable to folks building 1599 embedded systems, but has complications. Carry on reading, 1600 and it is assumed you know what you need. 1601 1602 *PLEASE* read random(4) and random(9) if you are in the 1603 habit of tweaking kernel configs, and/or if you are a member 1604 of the embedded community, wanting specific and not-usual 1605 behaviour from your security subsystems. 1606 1607 NOTE!! If you use RANDOM_DUMMY and/or have no 'device 1608 random', you will NOT have a functioning /dev/random, and 1609 many cryptographic features will not work, including SSH. 1610 You may also find strange behaviour from the random(3) set 1611 of library functions, in particular sranddev(3), srandomdev(3) 1612 and arc4random(3). The reason for this is that the KERN_ARND 1613 sysctl only returns entropy if it thinks it has some to 1614 share, and with RANDOM_DUMMY or no 'device random' this 1615 will never happen. 1616 161720150623: 1618 An additional fix for the issue described in the 20150614 sendmail 1619 entry below has been committed in revision 284717. 1620 162120150616: 1622 FreeBSD's old make (fmake) has been removed from the system. It is 1623 available as the devel/fmake port or via pkg install fmake. 1624 162520150615: 1626 The fix for the issue described in the 20150614 sendmail entry 1627 below has been committed in revision 284436. The work 1628 around described in that entry is no longer needed unless the 1629 default setting is overridden by a confDH_PARAMETERS configuration 1630 setting of '5' or pointing to a 512 bit DH parameter file. 1631 163220150614: 1633 ALLOW_DEPRECATED_ATF_TOOLS/ATFFILE support has been removed from 1634 atf.test.mk (included from bsd.test.mk). Please upgrade devel/atf 1635 and devel/kyua to version 0.20+ and adjust any calling code to work 1636 with Kyuafile and kyua. 1637 163820150614: 1639 The import of openssl to address the FreeBSD-SA-15:10.openssl 1640 security advisory includes a change which rejects handshakes 1641 with DH parameters below 768 bits. sendmail releases prior 1642 to 8.15.2 (not yet released), defaulted to a 512 bit 1643 DH parameter setting for client connections. To work around 1644 this interoperability, sendmail can be configured to use a 1645 2048 bit DH parameter by: 1646 1647 1. Edit /etc/mail/`hostname`.mc 1648 2. If a setting for confDH_PARAMETERS does not exist or 1649 exists and is set to a string beginning with '5', 1650 replace it with '2'. 1651 3. If a setting for confDH_PARAMETERS exists and is set to 1652 a file path, create a new file with: 1653 openssl dhparam -out /path/to/file 2048 1654 4. Rebuild the .cf file: 1655 cd /etc/mail/; make; make install 1656 5. Restart sendmail: 1657 cd /etc/mail/; make restart 1658 1659 A sendmail patch is coming, at which time this file will be 1660 updated. 1661 166220150604: 1663 Generation of legacy formatted entries have been disabled by default 1664 in pwd_mkdb(8), as all base system consumers of the legacy formatted 1665 entries were converted to use the new format by default when the new, 1666 machine independent format have been added and supported since FreeBSD 1667 5.x. 1668 1669 Please see the pwd_mkdb(8) manual page for further details. 1670 167120150525: 1672 Clang and llvm have been upgraded to 3.6.1 release. Please see the 1673 20141231 entry below for information about prerequisites and upgrading, 1674 if you are not already using 3.5.0 or higher. 1675 167620150521: 1677 TI platform code switched to using vendor DTS files and this update 1678 may break existing systems running on Beaglebone, Beaglebone Black, 1679 and Pandaboard: 1680 1681 - dtb files should be regenerated/reinstalled. Filenames are the 1682 same but content is different now 1683 - GPIO addressing was changed, now each GPIO bank (32 pins per bank) 1684 has its own /dev/gpiocX device, e.g. pin 121 on /dev/gpioc0 in old 1685 addressing scheme is now pin 25 on /dev/gpioc3. 1686 - Pandaboard: /etc/ttys should be updated, serial console device is 1687 now /dev/ttyu2, not /dev/ttyu0 1688 168920150501: 1690 soelim(1) from gnu/usr.bin/groff has been replaced by usr.bin/soelim. 1691 If you need the GNU extension from groff soelim(1), install groff 1692 from package: pkg install groff, or via ports: textproc/groff. 1693 169420150423: 1695 chmod, chflags, chown and chgrp now affect symlinks in -R mode as 1696 defined in symlink(7); previously symlinks were silently ignored. 1697 169820150415: 1699 The const qualifier has been removed from iconv(3) to comply with 1700 POSIX. The ports tree is aware of this from r384038 onwards. 1701 170220150416: 1703 Libraries specified by LIBADD in Makefiles must have a corresponding 1704 DPADD_<lib> variable to ensure correct dependencies. This is now 1705 enforced in src.libnames.mk. 1706 170720150324: 1708 From legacy ata(4) driver was removed support for SATA controllers 1709 supported by more functional drivers ahci(4), siis(4) and mvs(4). 1710 Kernel modules ataahci and ataadaptec were removed completely, 1711 replaced by ahci and mvs modules respectively. 1712 171320150315: 1714 Clang, llvm and lldb have been upgraded to 3.6.0 release. Please see 1715 the 20141231 entry below for information about prerequisites and 1716 upgrading, if you are not already using 3.5.0 or higher. 1717 171820150307: 1719 The 32-bit PowerPC kernel has been changed to a position-independent 1720 executable. This can only be booted with a version of loader(8) 1721 newer than January 31, 2015, so make sure to update both world and 1722 kernel before rebooting. 1723 172420150217: 1725 If you are running a -CURRENT kernel since r273872 (Oct 30th, 2014), 1726 but before r278950, the RNG was not seeded properly. Immediately 1727 upgrade the kernel to r278950 or later and regenerate any keys (e.g. 1728 ssh keys or openssl keys) that were generated w/ a kernel from that 1729 range. This does not affect programs that directly used /dev/random 1730 or /dev/urandom. All userland uses of arc4random(3) are affected. 1731 173220150210: 1733 The autofs(4) ABI was changed in order to restore binary compatibility 1734 with 10.1-RELEASE. The automountd(8) daemon needs to be rebuilt to work 1735 with the new kernel. 1736 173720150131: 1738 The powerpc64 kernel has been changed to a position-independent 1739 executable. This can only be booted with a new version of loader(8), 1740 so make sure to update both world and kernel before rebooting. 1741 174220150118: 1743 Clang and llvm have been upgraded to 3.5.1 release. This is a bugfix 1744 only release, no new features have been added. Please see the 20141231 1745 entry below for information about prerequisites and upgrading, if you 1746 are not already using 3.5.0. 1747 174820150107: 1749 ELF tools addr2line, elfcopy (strip), nm, size, and strings are now 1750 taken from the ELF Tool Chain project rather than GNU binutils. They 1751 should be drop-in replacements, with the addition of arm64 support. 1752 The WITHOUT_ELFTOOLCHAIN_TOOLS= knob may be used to obtain the 1753 binutils tools, if necessary. See 20150805 for updated information. 1754 175520150105: 1756 The default Unbound configuration now enables remote control 1757 using a local socket. Users who have already enabled the 1758 local_unbound service should regenerate their configuration 1759 by running "service local_unbound setup" as root. 1760 176120150102: 1762 The GNU texinfo and GNU info pages have been removed. 1763 To be able to view GNU info pages please install texinfo from ports. 1764 176520141231: 1766 Clang, llvm and lldb have been upgraded to 3.5.0 release. 1767 1768 As of this release, a prerequisite for building clang, llvm and lldb is 1769 a C++11 capable compiler and C++11 standard library. This means that to 1770 be able to successfully build the cross-tools stage of buildworld, with 1771 clang as the bootstrap compiler, your system compiler or cross compiler 1772 should either be clang 3.3 or later, or gcc 4.8 or later, and your 1773 system C++ library should be libc++, or libdstdc++ from gcc 4.8 or 1774 later. 1775 1776 On any standard FreeBSD 10.x or 11.x installation, where clang and 1777 libc++ are on by default (that is, on x86 or arm), this should work out 1778 of the box. 1779 1780 On 9.x installations where clang is enabled by default, e.g. on x86 and 1781 powerpc, libc++ will not be enabled by default, so libc++ should be 1782 built (with clang) and installed first. If both clang and libc++ are 1783 missing, build clang first, then use it to build libc++. 1784 1785 On 8.x and earlier installations, upgrade to 9.x first, and then follow 1786 the instructions for 9.x above. 1787 1788 Sparc64 and mips users are unaffected, as they still use gcc 4.2.1 by 1789 default, and do not build clang. 1790 1791 Many embedded systems are resource constrained, and will not be able to 1792 build clang in a reasonable time, or in some cases at all. In those 1793 cases, cross building bootable systems on amd64 is a workaround. 1794 1795 This new version of clang introduces a number of new warnings, of which 1796 the following are most likely to appear: 1797 1798 -Wabsolute-value 1799 1800 This warns in two cases, for both C and C++: 1801 * When the code is trying to take the absolute value of an unsigned 1802 quantity, which is effectively a no-op, and almost never what was 1803 intended. The code should be fixed, if at all possible. If you are 1804 sure that the unsigned quantity can be safely cast to signed, without 1805 loss of information or undefined behavior, you can add an explicit 1806 cast, or disable the warning. 1807 1808 * When the code is trying to take an absolute value, but the called 1809 abs() variant is for the wrong type, which can lead to truncation. 1810 If you want to disable the warning instead of fixing the code, please 1811 make sure that truncation will not occur, or it might lead to unwanted 1812 side-effects. 1813 1814 -Wtautological-undefined-compare and 1815 -Wundefined-bool-conversion 1816 1817 These warn when C++ code is trying to compare 'this' against NULL, while 1818 'this' should never be NULL in well-defined C++ code. However, there is 1819 some legacy (pre C++11) code out there, which actively abuses this 1820 feature, which was less strictly defined in previous C++ versions. 1821 1822 Squid and openjdk do this, for example. The warning can be turned off 1823 for C++98 and earlier, but compiling the code in C++11 mode might result 1824 in unexpected behavior; for example, the parts of the program that are 1825 unreachable could be optimized away. 1826 182720141222: 1828 The old NFS client and server (kernel options NFSCLIENT, NFSSERVER) 1829 kernel sources have been removed. The .h files remain, since some 1830 utilities include them. This will need to be fixed later. 1831 If "mount -t oldnfs ..." is attempted, it will fail. 1832 If the "-o" option on mountd(8), nfsd(8) or nfsstat(1) is used, 1833 the utilities will report errors. 1834 183520141121: 1836 The handling of LOCAL_LIB_DIRS has been altered to skip addition of 1837 directories to top level SUBDIR variable when their parent 1838 directory is included in LOCAL_DIRS. Users with build systems with 1839 such hierarchies and without SUBDIR entries in the parent 1840 directory Makefiles should add them or add the directories to 1841 LOCAL_DIRS. 1842 184320141109: 1844 faith(4) and faithd(8) have been removed from the base system. Faith 1845 has been obsolete for a very long time. 1846 184720141104: 1848 vt(4), the new console driver, is enabled by default. It brings 1849 support for Unicode and double-width characters, as well as 1850 support for UEFI and integration with the KMS kernel video 1851 drivers. 1852 1853 You may need to update your console settings in /etc/rc.conf, 1854 most probably the keymap. During boot, /etc/rc.d/syscons will 1855 indicate what you need to do. 1856 1857 vt(4) still has issues and lacks some features compared to 1858 syscons(4). See the wiki for up-to-date information: 1859 https://wiki.freebsd.org/Newcons 1860 1861 If you want to keep using syscons(4), you can do so by adding 1862 the following line to /boot/loader.conf: 1863 kern.vty=sc 1864 186520141102: 1866 pjdfstest has been integrated into kyua as an opt-in test suite. 1867 Please see share/doc/pjdfstest/README for more details on how to 1868 execute it. 1869 187020141009: 1871 gperf has been removed from the base system for architectures 1872 that use clang. Ports that require gperf will obtain it from the 1873 devel/gperf port. 1874 187520140923: 1876 pjdfstest has been moved from tools/regression/pjdfstest to 1877 contrib/pjdfstest . 1878 187920140922: 1880 At svn r271982, The default linux compat kernel ABI has been adjusted 1881 to 2.6.18 in support of the linux-c6 compat ports infrastructure 1882 update. If you wish to continue using the linux-f10 compat ports, 1883 add compat.linux.osrelease=2.6.16 to your local sysctl.conf. Users are 1884 encouraged to update their linux-compat packages to linux-c6 during 1885 their next update cycle. 1886 188720140729: 1888 The ofwfb driver, used to provide a graphics console on PowerPC when 1889 using vt(4), no longer allows mmap() of all physical memory. This 1890 will prevent Xorg on PowerPC with some ATI graphics cards from 1891 initializing properly unless x11-servers/xorg-server is updated to 1892 1.12.4_8 or newer. 1893 189420140723: 1895 The xdev targets have been converted to using TARGET and 1896 TARGET_ARCH instead of XDEV and XDEV_ARCH. 1897 189820140719: 1899 The default unbound configuration has been modified to address 1900 issues with reverse lookups on networks that use private 1901 address ranges. If you use the local_unbound service, run 1902 "service local_unbound setup" as root to regenerate your 1903 configuration, then "service local_unbound reload" to load the 1904 new configuration. 1905 190620140709: 1907 The GNU texinfo and GNU info pages are not built and installed 1908 anymore, WITH_INFO knob has been added to allow to built and install 1909 them again. 1910 UPDATE: see 20150102 entry on texinfo's removal 1911 191220140708: 1913 The GNU readline library is now an INTERNALLIB - that is, it is 1914 statically linked into consumers (GDB and variants) in the base 1915 system, and the shared library is no longer installed. The 1916 devel/readline port is available for third party software that 1917 requires readline. 1918 191920140702: 1920 The Itanium architecture (ia64) has been removed from the list of 1921 known architectures. This is the first step in the removal of the 1922 architecture. 1923 192420140701: 1925 Commit r268115 has added NFSv4.1 server support, merged from 1926 projects/nfsv4.1-server. Since this includes changes to the 1927 internal interfaces between the NFS related modules, a full 1928 build of the kernel and modules will be necessary. 1929 __FreeBSD_version has been bumped. 1930 193120140629: 1932 The WITHOUT_VT_SUPPORT kernel config knob has been renamed 1933 WITHOUT_VT. (The other _SUPPORT knobs have a consistent meaning 1934 which differs from the behaviour controlled by this knob.) 1935 193620140619: 1937 Maximal length of the serial number in CTL was increased from 16 to 1938 64 chars, that breaks ABI. All CTL-related tools, such as ctladm 1939 and ctld, need to be rebuilt to work with a new kernel. 1940 194120140606: 1942 The libatf-c and libatf-c++ major versions were downgraded to 0 and 1943 1 respectively to match the upstream numbers. They were out of 1944 sync because, when they were originally added to FreeBSD, the 1945 upstream versions were not respected. These libraries are private 1946 and not yet built by default, so renumbering them should be a 1947 non-issue. However, unclean source trees will yield broken test 1948 programs once the operator executes "make delete-old-libs" after a 1949 "make installworld". 1950 1951 Additionally, the atf-sh binary was made private by moving it into 1952 /usr/libexec/. Already-built shell test programs will keep the 1953 path to the old binary so they will break after "make delete-old" 1954 is run. 1955 1956 If you are using WITH_TESTS=yes (not the default), wipe the object 1957 tree and rebuild from scratch to prevent spurious test failures. 1958 This is only needed once: the misnumbered libraries and misplaced 1959 binaries have been added to OptionalObsoleteFiles.inc so they will 1960 be removed during a clean upgrade. 1961 196220140512: 1963 Clang and llvm have been upgraded to 3.4.1 release. 1964 196520140508: 1966 We bogusly installed src.opts.mk in /usr/share/mk. This file should 1967 be removed to avoid issues in the future (and has been added to 1968 ObsoleteFiles.inc). 1969 197020140505: 1971 /etc/src.conf now affects only builds of the FreeBSD src tree. In the 1972 past, it affected all builds that used the bsd.*.mk files. The old 1973 behavior was a bug, but people may have relied upon it. To get this 1974 behavior back, you can .include /etc/src.conf from /etc/make.conf 1975 (which is still global and isn't changed). This also changes the 1976 behavior of incremental builds inside the tree of individual 1977 directories. Set MAKESYSPATH to ".../share/mk" to do that. 1978 Although this has survived make universe and some upgrade scenarios, 1979 other upgrade scenarios may have broken. At least one form of 1980 temporary breakage was fixed with MAKESYSPATH settings for buildworld 1981 as well... In cases where MAKESYSPATH isn't working with this 1982 setting, you'll need to set it to the full path to your tree. 1983 1984 One side effect of all this cleaning up is that bsd.compiler.mk 1985 is no longer implicitly included by bsd.own.mk. If you wish to 1986 use COMPILER_TYPE, you must now explicitly include bsd.compiler.mk 1987 as well. 1988 198920140430: 1990 The lindev device has been removed since /dev/full has been made a 1991 standard device. __FreeBSD_version has been bumped. 1992 199320140424: 1994 The knob WITHOUT_VI was added to the base system, which controls 1995 building ex(1), vi(1), etc. Older releases of FreeBSD required ex(1) 1996 in order to reorder files share/termcap and didn't build ex(1) as a 1997 build tool, so building/installing with WITH_VI is highly advised for 1998 build hosts for older releases. 1999 2000 This issue has been fixed in stable/9 and stable/10 in r277022 and 2001 r276991, respectively. 2002 200320140418: 2004 The YES_HESIOD knob has been removed. It has been obsolete for 2005 a decade. Please move to using WITH_HESIOD instead or your builds 2006 will silently lack HESIOD. 2007 200820140405: 2009 The uart(4) driver has been changed with respect to its handling 2010 of the low-level console. Previously the uart(4) driver prevented 2011 any process from changing the baudrate or the CLOCAL and HUPCL 2012 control flags. By removing the restrictions, operators can make 2013 changes to the serial console port without having to reboot. 2014 However, when getty(8) is started on the serial device that is 2015 associated with the low-level console, a misconfigured terminal 2016 line in /etc/ttys will now have a real impact. 2017 Before upgrading the kernel, make sure that /etc/ttys has the 2018 serial console device configured as 3wire without baudrate to 2019 preserve the previous behaviour. E.g: 2020 ttyu0 "/usr/libexec/getty 3wire" vt100 on secure 2021 202220140306: 2023 Support for libwrap (TCP wrappers) in rpcbind was disabled by default 2024 to improve performance. To re-enable it, if needed, run rpcbind 2025 with command line option -W. 2026 202720140226: 2028 Switched back to the GPL dtc compiler due to updates in the upstream 2029 dts files not being supported by the BSDL dtc compiler. You will need 2030 to rebuild your kernel toolchain to pick up the new compiler. Core dumps 2031 may result while building dtb files during a kernel build if you fail 2032 to do so. Set WITHOUT_GPL_DTC if you require the BSDL compiler. 2033 203420140216: 2035 Clang and llvm have been upgraded to 3.4 release. 2036 203720140216: 2038 The nve(4) driver has been removed. Please use the nfe(4) driver 2039 for NVIDIA nForce MCP Ethernet adapters instead. 2040 204120140212: 2042 An ABI incompatibility crept into the libc++ 3.4 import in r261283. 2043 This could cause certain C++ applications using shared libraries built 2044 against the previous version of libc++ to crash. The incompatibility 2045 has now been fixed, but any C++ applications or shared libraries built 2046 between r261283 and r261801 should be recompiled. 2047 204820140204: 2049 OpenSSH will now ignore errors caused by kernel lacking of Capsicum 2050 capability mode support. Please note that enabling the feature in 2051 kernel is still highly recommended. 2052 205320140131: 2054 OpenSSH is now built with sandbox support, and will use sandbox as 2055 the default privilege separation method. This requires Capsicum 2056 capability mode support in kernel. 2057 205820140128: 2059 The libelf and libdwarf libraries have been updated to newer 2060 versions from upstream. Shared library version numbers for 2061 these two libraries were bumped. Any ports or binaries 2062 requiring these two libraries should be recompiled. 2063 __FreeBSD_version is bumped to 1100006. 2064 206520140110: 2066 If a Makefile in a tests/ directory was auto-generating a Kyuafile 2067 instead of providing an explicit one, this would prevent such 2068 Makefile from providing its own Kyuafile in the future during 2069 NO_CLEAN builds. This has been fixed in the Makefiles but manual 2070 intervention is needed to clean an objdir if you use NO_CLEAN: 2071 # find /usr/obj -name Kyuafile | xargs rm -f 2072 207320131213: 2074 The behavior of gss_pseudo_random() for the krb5 mechanism 2075 has changed, for applications requesting a longer random string 2076 than produced by the underlying enctype's pseudo-random() function. 2077 In particular, the random string produced from a session key of 2078 enctype aes256-cts-hmac-sha1-96 or aes256-cts-hmac-sha1-96 will 2079 be different at the 17th octet and later, after this change. 2080 The counter used in the PRF+ construction is now encoded as a 2081 big-endian integer in accordance with RFC 4402. 2082 __FreeBSD_version is bumped to 1100004. 2083 208420131108: 2085 The WITHOUT_ATF build knob has been removed and its functionality 2086 has been subsumed into the more generic WITHOUT_TESTS. If you were 2087 using the former to disable the build of the ATF libraries, you 2088 should change your settings to use the latter. 2089 209020131025: 2091 The default version of mtree is nmtree which is obtained from 2092 NetBSD. The output is generally the same, but may vary 2093 slightly. If you found you need identical output adding 2094 "-F freebsd9" to the command line should do the trick. For the 2095 time being, the old mtree is available as fmtree. 2096 209720131014: 2098 libbsdyml has been renamed to libyaml and moved to /usr/lib/private. 2099 This will break ports-mgmt/pkg. Rebuild the port, or upgrade to pkg 2100 1.1.4_8 and verify bsdyml not linked in, before running "make 2101 delete-old-libs": 2102 # make -C /usr/ports/ports-mgmt/pkg build deinstall install clean 2103 or 2104 # pkg install pkg; ldd /usr/local/sbin/pkg | grep bsdyml 2105 210620131010: 2107 The stable/10 branch has been created in subversion from head 2108 revision r256279. 2109 2110COMMON ITEMS: 2111 2112 General Notes 2113 ------------- 2114 Sometimes, obscure build problems are the result of environment 2115 poisoning. This can happen because the make utility reads its 2116 environment when searching for values for global variables. To run 2117 your build attempts in an "environmental clean room", prefix all make 2118 commands with 'env -i '. See the env(1) manual page for more details. 2119 Occasionally a build failure will occur with "make -j" due to a race 2120 condition. If this happens try building again without -j, and please 2121 report a bug if it happens consistently. 2122 2123 When upgrading from one major version to another it is generally best to 2124 upgrade to the latest code in the currently installed branch first, then 2125 do an upgrade to the new branch. This is the best-tested upgrade path, 2126 and has the highest probability of being successful. Please try this 2127 approach if you encounter problems with a major version upgrade. Since 2128 the stable 4.x branch point, one has generally been able to upgrade from 2129 anywhere in the most recent stable branch to head / current (or even the 2130 last couple of stable branches). See the top of this file when there's 2131 an exception. 2132 2133 The update process will emit an error on an attempt to perform a build 2134 or install from a FreeBSD version below the earliest supported version. 2135 When updating from an older version the update should be performed one 2136 major release at a time, including running `make delete-old` at each 2137 step. 2138 2139 When upgrading a live system, having a root shell around before 2140 installing anything can help undo problems. Not having a root shell 2141 around can lead to problems if pam has changed too much from your 2142 starting point to allow continued authentication after the upgrade. 2143 2144 This file should be read as a log of events. When a later event changes 2145 information of a prior event, the prior event should not be deleted. 2146 Instead, a pointer to the entry with the new information should be 2147 placed in the old entry. Readers of this file should also sanity check 2148 older entries before relying on them blindly. Authors of new entries 2149 should write them with this in mind. 2150 2151 ZFS notes 2152 --------- 2153 When upgrading the boot ZFS pool to a new version, always follow 2154 these two steps: 2155 2156 1.) recompile and reinstall the ZFS boot loader and boot block 2157 (this is part of "make buildworld" and "make installworld") 2158 2159 2.) update the ZFS boot block on your boot drive 2160 2161 The following example updates the ZFS boot block on the first 2162 partition (freebsd-boot) of a GPT partitioned drive ada0: 2163 "gpart bootcode -p /boot/gptzfsboot -i 1 ada0" 2164 2165 Non-boot pools do not need these updates. 2166 2167 To build a kernel 2168 ----------------- 2169 If you are updating from a prior version of FreeBSD (even one just 2170 a few days old), you should follow this procedure. It is the most 2171 failsafe as it uses a /usr/obj tree with a fresh mini-buildworld, 2172 2173 make kernel-toolchain 2174 make -DALWAYS_CHECK_MAKE buildkernel KERNCONF=YOUR_KERNEL_HERE 2175 make -DALWAYS_CHECK_MAKE installkernel KERNCONF=YOUR_KERNEL_HERE 2176 2177 To test a kernel once 2178 --------------------- 2179 If you just want to boot a kernel once (because you are not sure 2180 if it works, or if you want to boot a known bad kernel to provide 2181 debugging information) run 2182 make installkernel KERNCONF=YOUR_KERNEL_HERE KODIR=/boot/testkernel 2183 nextboot -k testkernel 2184 2185 To rebuild everything and install it on the current system. 2186 ----------------------------------------------------------- 2187 # Note: sometimes if you are running current you gotta do more than 2188 # is listed here if you are upgrading from a really old current. 2189 2190 <make sure you have good level 0 dumps> 2191 make buildworld 2192 make buildkernel KERNCONF=YOUR_KERNEL_HERE 2193 make installkernel KERNCONF=YOUR_KERNEL_HERE 2194 [1] 2195 <reboot in single user> [3] 2196 mergemaster -Fp [5] 2197 make installworld 2198 mergemaster -Fi [4] 2199 make delete-old [6] 2200 <reboot> 2201 2202 To cross-install current onto a separate partition 2203 -------------------------------------------------- 2204 # In this approach we use a separate partition to hold 2205 # current's root, 'usr', and 'var' directories. A partition 2206 # holding "/", "/usr" and "/var" should be about 2GB in 2207 # size. 2208 2209 <make sure you have good level 0 dumps> 2210 <boot into -stable> 2211 make buildworld 2212 make buildkernel KERNCONF=YOUR_KERNEL_HERE 2213 <maybe newfs current's root partition> 2214 <mount current's root partition on directory ${CURRENT_ROOT}> 2215 make installworld DESTDIR=${CURRENT_ROOT} -DDB_FROM_SRC 2216 make distribution DESTDIR=${CURRENT_ROOT} # if newfs'd 2217 make installkernel KERNCONF=YOUR_KERNEL_HERE DESTDIR=${CURRENT_ROOT} 2218 cp /etc/fstab ${CURRENT_ROOT}/etc/fstab # if newfs'd 2219 <edit ${CURRENT_ROOT}/etc/fstab to mount "/" from the correct partition> 2220 <reboot into current> 2221 <do a "native" rebuild/install as described in the previous section> 2222 <maybe install compatibility libraries from ports/misc/compat*> 2223 <reboot> 2224 2225 2226 To upgrade in-place from stable to current 2227 ---------------------------------------------- 2228 <make sure you have good level 0 dumps> 2229 make buildworld [9] 2230 make buildkernel KERNCONF=YOUR_KERNEL_HERE [8] 2231 make installkernel KERNCONF=YOUR_KERNEL_HERE 2232 [1] 2233 <reboot in single user> [3] 2234 mergemaster -Fp [5] 2235 make installworld 2236 mergemaster -Fi [4] 2237 make delete-old [6] 2238 <reboot> 2239 2240 Make sure that you've read the UPDATING file to understand the 2241 tweaks to various things you need. At this point in the life 2242 cycle of current, things change often and you are on your own 2243 to cope. The defaults can also change, so please read ALL of 2244 the UPDATING entries. 2245 2246 Also, if you are tracking -current, you must be subscribed to 2247 freebsd-current@freebsd.org. Make sure that before you update 2248 your sources that you have read and understood all the recent 2249 messages there. If in doubt, please track -stable which has 2250 much fewer pitfalls. 2251 2252 [1] If you have third party modules, such as vmware, you 2253 should disable them at this point so they don't crash your 2254 system on reboot. 2255 2256 [3] From the bootblocks, boot -s, and then do 2257 fsck -p 2258 mount -u / 2259 mount -a 2260 sh /etc/rc.d/zfs start # mount zfs filesystem, if needed 2261 cd src # full path to source 2262 adjkerntz -i # if CMOS is wall time 2263 Also, when doing a major release upgrade, it is required that 2264 you boot into single user mode to do the installworld. 2265 2266 [4] Note: This step is non-optional. Failure to do this step 2267 can result in a significant reduction in the functionality of the 2268 system. Attempting to do it by hand is not recommended and those 2269 that pursue this avenue should read this file carefully, as well 2270 as the archives of freebsd-current and freebsd-hackers mailing lists 2271 for potential gotchas. The -U option is also useful to consider. 2272 See mergemaster(8) for more information. 2273 2274 [5] Usually this step is a no-op. However, from time to time 2275 you may need to do this if you get unknown user in the following 2276 step. It never hurts to do it all the time. You may need to 2277 install a new mergemaster (cd src/usr.sbin/mergemaster && make 2278 install) after the buildworld before this step if you last updated 2279 from current before 20130425 or from -stable before 20130430. 2280 2281 [6] This only deletes old files and directories. Old libraries 2282 can be deleted by "make delete-old-libs", but you have to make 2283 sure that no program is using those libraries anymore. 2284 2285 [8] The new kernel must be able to run existing binaries used by an 2286 installworld. When upgrading across major versions, the new kernel's 2287 configuration must include the correct COMPAT_FREEBSD<n> option for 2288 existing binaries (e.g. COMPAT_FREEBSD11 to run 11.x binaries). Failure 2289 to do so may leave you with a system that is hard to boot to recover. A 2290 GENERIC kernel will include suitable compatibility options to run 2291 binaries from older branches. Note that the ability to run binaries 2292 from unsupported branches is not guaranteed. 2293 2294 Make sure that you merge any new devices from GENERIC since the 2295 last time you updated your kernel config file. Options also 2296 change over time, so you may need to adjust your custom kernels 2297 for these as well. 2298 2299 [9] If CPUTYPE is defined in your /etc/make.conf, make sure to use the 2300 "?=" instead of the "=" assignment operator, so that buildworld can 2301 override the CPUTYPE if it needs to. 2302 2303 MAKEOBJDIRPREFIX must be defined in an environment variable, and 2304 not on the command line, or in /etc/make.conf. buildworld will 2305 warn if it is improperly defined. 2306FORMAT: 2307 2308This file contains a list, in reverse chronological order, of major 2309breakages in tracking -current. It is not guaranteed to be a complete 2310list of such breakages, and only contains entries since September 23, 2011. 2311If you need to see UPDATING entries from before that date, you will need 2312to fetch an UPDATING file from an older FreeBSD release. 2313 2314Copyright information: 2315 2316Copyright 1998-2009 M.
