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 WITH_MALLOC_PRODUCTION in /etc/src.conf and rebuild 26 world, or to merely disable the most expensive debugging functionality 27 at runtime, run "ln -s 'abort:false,junk:false' /etc/malloc.conf".) 28 2920201216: 30 The services database has been updated to cover more of the basic 31 services expected in a modern system. The database is big enough 32 that it will cause issues in mergemaster in Releases previous to 33 12.2 and 11.3, or in very old current systems from before r358154. 34 3520201215: 36 Obsolete in-tree GDB 6.1.1 has been removed. GDB (including kgdb) 37 may be installed from ports or packages. 38 3920201124: 40 ping6 has been merged into ping. It can now be called as "ping -6". 41 See ping(8) for details. 42 4320201108: 44 Default value of net.add_addr_allfibs has been changed to 0. 45 If you have multi-fib configuration and rely on existence of all 46 interface routes in every fib, you need to set the above sysctl to 1. 4720201030: 48 The internal pre-processor in the calendar(1) program has been 49 extended to support more C pre-processor commands (e.g. #ifdef, #else, 50 and #undef) and to detect unbalanced conditional statements. 51 Error messages have been extended to include the filename and line 52 number if processing stops to help fixing malformed data files. 53 5420201026: 55 All the data files for the calendar(1) program, except calendar.freebsd, 56 have been moved to the deskutils/calendar-data port, much like the 57 jewish calendar entries were moved to deskutils/hebcal years ago. After 58 make delete-old-files, you need to install it to retain full 59 functionality. calendar(1) will issue a reminder for files it can't 60 find. 61 6220200923: 63 LINT files are no longer generated. We now include the relevant NOTES 64 files. Note: This may cause conflicts with updating in some cases. 65 find sys -name LINT\* -delete 66 is suggested across this commit to remove the generated LINT files. 67 68 If you have tried to update with generated files there, the svn 69 command you want to un-auger the tree is 70 cd sys/amd64/conf 71 svn revert -R . 72 and then do the above find from the top level. Substitute 'amd64' 73 above with where the error message indicates a conflict. 74 7520200824: 76 OpenZFS support has been integrated. Do not upgrade root pools until 77 the loader is updated to support zstd. Furthermore, we caution against 78 'zpool upgrade' for the next few weeks. The change should be transparent 79 unless you want to use new features. 80 81 Not all "NO_CLEAN" build scenarios work across these changes. Many 82 scenarios have been tested and fixed, but rebuilding kernels without 83 rebuilding world may fail. 84 85 The ZFS cache file has moved from /boot to /etc to match the OpenZFS 86 upstream default. A fallback to /boot has been added for mountroot. 87 88 Pool auto import behavior at boot has been moved from the kernel module 89 to an explicit "zpool import -a" in one of the rc scripts enabled by 90 zfs_enable=YES. This means your non-root zpools won't auto import until 91 you upgrade your /etc/rc.d files. 92 9320200824: 94 The resume code now notifies devd with the 'kernel' system 95 rather than the old 'kern' subsystem to be consistent with 96 other use. The old notification will be created as well, but 97 will be removed prior to FreeBSD 14.0. 98 9920200821: 100 r362275 changed the internal API between the kernel RPC and the 101 NFS modules. As such, all the modules must be recompiled from 102 sources. 103 10420200817: 105 r364330 modified the internal API used between the NFS modules. 106 As such, all the NFS modules must be re-compiled from sources. 107 10820200816: 109 Clang, llvm, lld, lldb, compiler-rt, libc++, libunwind and openmp have 110 been upgraded to 11.0.0. Please see the 20141231 entry below for 111 information about prerequisites and upgrading, if you are not already 112 using clang 3.5.0 or higher. 113 11420200810: 115 r364092 modified the internal ABI used between the kernel NFS 116 modules. As such, all of these modules need to be rebuilt 117 from sources, so a version bump was done. 118 11920200807: 120 Makefile.inc has been updated to work around the issue documented in 121 20200729. It was a case where the optimization of using symbolic links 122 to point to binaries created a situation where we'd run new binaries 123 with old libraries starting midway through the installworld process. 124 12520200729: 126 r363679 has redefined some undefined behavior in regcomp(3); notably, 127 extraneous escapes of most ordinary characters will no longer be 128 accepted. An exp-run has identified all of the problems with this in 129 ports, but other non-ports software may need extra escapes removed to 130 continue to function. 131 132 Because of this change, installworld may encounter the following error 133 from rtld: Undefined symbol "regcomp@FBSD_1.6" -- It is imperative that 134 you do not halt installworld. Instead, let it run to completion (whether 135 successful or not) and run installworld once more. 136 13720200627: 138 A new implementation of bc and dc has been imported in r362681. This 139 implementation corrects non-conformant behavior of the previous bc 140 and adds GNU bc compatible options. It offers a number of extensions, 141 is much faster on large values, and has support for message catalogs 142 (a number of languages are already supported, contributions of further 143 languages welcome). The option WITHOUT_GH_BC can be used to build the 144 world with the previous versions of bc and dc. 145 14620200625: 147 r362639 changed the internal API used between the NFS kernel modules. 148 As such, they all need to be rebuilt from sources. 149 15020200613: 151 r362158 changed the arguments for VFS_CHECKEXP(). As such, any 152 out of tree file systems need to be modified and rebuilt. 153 Also, any file systems that are modules must be rebuilt. 154 15520200604: 156 read(2) of a directory fd is now rejected by default. root may 157 re-enable it for system root only on non-ZFS filesystems with the 158 security.bsd.allow_read_dir sysctl(8) MIB if 159 security.bsd.suser_enabled=1. 160 161 It may be advised to setup aliases for grep to default to `-d skip` if 162 commonly non-recursively grepping a list that includes directories and 163 the potential for the resulting stderr output is not tolerable. Example 164 aliases are now installed, commented out, in /root/.cshrc and 165 /root/.shrc. 166 16720200523: 168 Clang, llvm, lld, lldb, compiler-rt, libc++, libunwind and openmp have 169 been upgraded to 10.0.1. Please see the 20141231 entry below for 170 information about prerequisites and upgrading, if you are not already 171 using clang 3.5.0 or higher. 172 17320200512: 174 Support for obsolete compilers has been removed from the build system. 175 Clang 6 and GCC 6.4 are the minimum supported versions. 176 17720200424: 178 closefrom(2) has been moved under COMPAT12, and replaced in libc with a 179 stub that calls close_range(2). If using a custom kernel configuration, 180 you may want to ensure that the COMPAT_FREEBSD12 option is included, as 181 a slightly older -CURRENT userland and older FreeBSD userlands may not 182 be functional without closefrom(2). 183 18420200414: 185 Upstream DTS from Linux 5.6 was merged and they now have the SID 186 and THS (Secure ID controller and THermal Sensor) node present. 187 The DTB overlays have now been removed from the tree for the H3/H5 and 188 A64 SoCs and the aw_sid and aw_thermal driver have been updated to 189 deal with upstream DTS. If you are using those overlays you need to 190 remove them from loader.conf and update the DTBs on the FAT partition. 191 19220200310: 193 Clang, llvm, lld, lldb, compiler-rt, libc++, libunwind and openmp have 194 been upgraded to 10.0.0. Please see the 20141231 entry below for 195 information about prerequisites and upgrading, if you are not already 196 using clang 3.5.0 or higher. 197 19820200309: 199 The amd(8) automount daemon has been removed from the source tree. 200 As of FreeBSD 10.1 autofs(5) is the preferred tool for automounting. 201 amd is still available in the sysutils/am-utils port. 202 20320200301: 204 Removed brooktree driver (bktr.4) from the tree. 205 20620200229: 207 The WITH_GPL_DTC option has been removed. The BSD-licenced device tree 208 compiler in usr.bin/dtc is used on all architectures which use dtc, and 209 the GPL dtc is available (if needed) from the sysutils/dtc port. 210 21120200229: 212 The WITHOUT_LLVM_LIBUNWIND option has been removed. LLVM's libunwind 213 is used by all supported CPU architectures. 214 21520200229: 216 GCC 4.2.1 has been removed from the tree. The WITH_GCC, 217 WITH_GCC_BOOTSTRAP, and WITH_GNUCXX options are no longer available. 218 Users who wish to build FreeBSD with GCC must use the external toolchain 219 ports or packages. 220 22120200220: 222 ncurses has been updated to a newer version (6.2-20200215). Given the ABI 223 has changed, users will have to rebuild all the ports that are linked to 224 ncurses. 225 22620200217: 227 The size of struct vnet and the magic cookie have changed. 228 Users need to recompile libkvm and all modules using VIMAGE 229 together with their new kernel. 230 23120200212: 232 Defining the long deprecated NO_CTF, NO_DEBUG_FILES, NO_INSTALLLIB, 233 NO_MAN, NO_PROFILE, and NO_WARNS variables is now an error. Update 234 your Makefiles and scripts to define MK_<var>=no instead as required. 235 236 One exception to this is that program or library Makefiles should 237 define MAN to empty rather than setting MK_MAN=no. 238 23920200108: 240 Clang/LLVM is now the default compiler and LLD the default 241 linker for riscv64. 242 24320200107: 244 make universe no longer uses GCC 4.2.1 on any architectures. 245 Architectures not supported by in-tree Clang/LLVM require an 246 external toolchain package. 247 24820200104: 249 GCC 4.2.1 is now not built by default, as part of the GCC 4.2.1 250 retirement plan. Specifically, the GCC, GCC_BOOTSTRAP, and GNUCXX 251 options default to off for all supported CPU architectures. As a 252 short-term transition aid they may be enabled via WITH_* options. 253 GCC 4.2.1 is expected to be removed from the tree on 2020-03-31. 254 25520200102: 256 Support for armv5 has been disconnected and is being removed. The 257 machine combination MACHINE=arm MACHINE_ARCH=arm is no longer valid. 258 You must now use a MACHINE_ARCH of armv6 or armv7. The default 259 MACHINE_ARCH for MACHINE=arm is now armv7. 260 26120191226: 262 Clang/LLVM is now the default compiler for all powerpc architectures. 263 LLD is now the default linker for powerpc64. The change for powerpc64 264 also includes a change to the ELFv2 ABI, incompatible with the existing 265 ABI. 266 26720191226: 268 Kernel-loadable random(4) modules are no longer unloadable. 269 27020191222: 271 Clang, llvm, lld, lldb, compiler-rt, libc++, libunwind and openmp have 272 been upgraded to 9.0.1. Please see the 20141231 entry below for 273 information about prerequisites and upgrading, if you are not already 274 using clang 3.5.0 or higher. 275 27620191212: 277 r355677 has modified the internal interface used between the 278 NFS modules in the kernel. As such, they must all be upgraded 279 simultaneously. I will do a version bump for this. 280 28120191205: 282 The root certificates of the Mozilla CA Certificate Store have been 283 imported into the base system and can be managed with the certctl(8) 284 utility. If you have installed the security/ca_root_nss port or package 285 with the ETCSYMLINK option (the default), be advised that there may be 286 differences between those included in the port and those included in 287 base due to differences in nss branch used as well as general update 288 frequency. Note also that certctl(8) cannot manage certs in the 289 format used by the security/ca_root_nss port. 290 29120191120: 292 The amd(8) automount daemon has been disabled by default, and will be 293 removed in the future. As of FreeBSD 10.1 the autofs(5) is available 294 for automounting. 295 29620191107: 297 The nctgpio and wbwd drivers have been moved to the superio bus. 298 If you have one of these drivers in a kernel configuration, then 299 you should add device superio to it. If you use one of these drivers 300 as a module and you compile a custom set of modules, then you should 301 add superio to the set. 302 30320191021: 304 KPIs for network drivers to access interface addresses have changed. 305 Users need to recompile NIC driver modules together with kernel. 306 30720191021: 308 The net.link.tap.user_open sysctl no longer prevents user opening of 309 already created /dev/tapNN devices. Access is still controlled by 310 node permissions, just like tun devices. The net.link.tap.user_open 311 sysctl is now used only to allow users to perform devfs cloning of 312 tap devices, and the subsequent open may not succeed if the user is not 313 in the appropriate group. This sysctl may be deprecated/removed 314 completely in the future. 315 31620191009: 317 mips, powerpc, and sparc64 are no longer built as part of 318 universe / tinderbox unless MAKE_OBSOLETE_GCC is defined. If 319 not defined, mips, powerpc, and sparc64 builds will look for 320 the xtoolchain binaries and if installed use them for universe 321 builds. As llvm 9.0 becomes vetted for these architectures, they 322 will be removed from the list. 323 32420191009: 325 Clang, llvm, lld, lldb, compiler-rt, libc++, libunwind and openmp have 326 been upgraded to 9.0.0. Please see the 20141231 entry below for 327 information about prerequisites and upgrading, if you are not already 328 using clang 3.5.0 or higher. 329 33020191003: 331 The hpt27xx, hptmv, hptnr, and hptrr drivers have been removed from 332 GENERIC. They are available as modules and can be loaded by adding 333 to /boot/loader.conf hpt27xx_load="YES", hptmv_load="YES", 334 hptnr_load="YES", or hptrr_load="YES", respectively. 335 33620190913: 337 ntpd no longer by default locks its pages in memory, allowing them 338 to be paged out by the kernel. Use rlimit memlock to restore 339 historic BSD behaviour. For example, add "rlimit memlock 32" 340 to ntp.conf to lock up to 32 MB of ntpd address space in memory. 341 34220190823: 343 Several of ping6's options have been renamed for better consistency 344 with ping. If you use any of -ARWXaghmrtwx, you must update your 345 scripts. See ping6(8) for details. 346 34720190727: 348 The vfs.fusefs.sync_unmount and vfs.fusefs.init_backgrounded sysctls 349 and the "-o sync_unmount" and "-o init_backgrounded" mount options have 350 been removed from mount_fusefs(8). You can safely remove them from 351 your scripts, because they had no effect. 352 353 The vfs.fusefs.fix_broken_io, vfs.fusefs.sync_resize, 354 vfs.fusefs.refresh_size, vfs.fusefs.mmap_enable, 355 vfs.fusefs.reclaim_revoked, and vfs.fusefs.data_cache_invalidate 356 sysctls have been removed. If you felt the need to set any of them to 357 a non-default value, please tell asomers@FreeBSD.org why. 358 35920190713: 360 Default permissions on the /var/account/acct file (and copies of it 361 rotated by periodic daily scripts) are changed from 0644 to 0640 362 because the file contains sensitive information that should not be 363 world-readable. If the /var/account directory must be created by 364 rc.d/accounting, the mode used is now 0750. Admins who use the 365 accounting feature are encouraged to change the mode of an existing 366 /var/account directory to 0750 or 0700. 367 36820190620: 369 Entropy collection and the /dev/random device are no longer optional 370 components. The "device random" option has been removed. 371 Implementations of distilling algorithms can still be made loadable 372 with "options RANDOM_LOADABLE" (e.g., random_fortuna.ko). 373 37420190612: 375 Clang, llvm, lld, lldb, compiler-rt, libc++, libunwind and openmp have 376 been upgraded to 8.0.1. Please see the 20141231 entry below for 377 information about prerequisites and upgrading, if you are not already 378 using clang 3.5.0 or higher. 379 38020190608: 381 A fix was applied to i386 kernel modules to avoid panics with 382 dpcpu or vnet. Users need to recompile i386 kernel modules 383 having pcpu or vnet sections or they will refuse to load. 384 38520190513: 386 User-wired pages now have their own counter, 387 vm.stats.vm.v_user_wire_count. The vm.max_wired sysctl was renamed 388 to vm.max_user_wired and changed from an unsigned int to an unsigned 389 long. bhyve VMs wired with the -S are now subject to the user 390 wiring limit; the vm.max_user_wired sysctl may need to be tuned to 391 avoid running into the limit. 392 39320190507: 394 The IPSEC option has been removed from GENERIC. Users requiring 395 ipsec(4) must now load the ipsec(4) kernel module. 396 39720190507: 398 The tap(4) driver has been folded into tun(4), and the module has been 399 renamed to tuntap. You should update any kld_list="if_tap" or 400 kld_list="if_tun" entries in /etc/rc.conf, if_tap_load="YES" or 401 if_tun_load="YES" entries in /boot/loader.conf to load the if_tuntap 402 module instead, and "device tap" or "device tun" entries in kernel 403 config files to select the tuntap device instead. 404 40520190418: 406 The following knobs have been added related to tradeoffs between 407 safe use of the random device and availability in the absence of 408 entropy: 409 410 kern.random.initial_seeding.bypass_before_seeding: tunable; set 411 non-zero to bypass the random device prior to seeding, or zero to 412 block random requests until the random device is initially seeded. 413 For now, set to 1 (unsafe) by default to restore pre-r346250 boot 414 availability properties. 415 416 kern.random.initial_seeding.read_random_bypassed_before_seeding: 417 read-only diagnostic sysctl that is set when bypass is enabled and 418 read_random(9) is bypassed, to enable programmatic handling of this 419 initial condition, if desired. 420 421 kern.random.initial_seeding.arc4random_bypassed_before_seeding: 422 Similar to the above, but for for arc4random(9) initial seeding. 423 424 kern.random.initial_seeding.disable_bypass_warnings: tunable; set 425 non-zero to disable warnings in dmesg when the same conditions are 426 met as for the diagnostic sysctls above. Defaults to zero, i.e., 427 produce warnings in dmesg when the conditions are met. 428 42920190416: 430 The loadable random module KPI has changed; the random_infra_init() 431 routine now requires a 3rd function pointer for a bool (*)(void) 432 method that returns true if the random device is seeded (and 433 therefore unblocked). 434 43520190404: 436 r345895 reverts r320698. This implies that an nfsuserd(8) daemon 437 built from head sources between r320757 (July 6, 2017) and 438 r338192 (Aug. 22, 2018) will not work unless the "-use-udpsock" 439 is added to the command line. 440 nfsuserd daemons built from head sources that are post-r338192 are 441 not affected and should continue to work. 442 44320190320: 444 The fuse(4) module has been renamed to fusefs(4) for consistency with 445 other filesystems. You should update any kld_load="fuse" entries in 446 /etc/rc.conf, fuse_load="YES" entries in /boot/loader.conf, and 447 "options FUSE" entries in kernel config files. 448 44920190304: 450 Clang, llvm, lld, lldb, compiler-rt and libc++ have been upgraded to 451 8.0.0. Please see the 20141231 entry below for information about 452 prerequisites and upgrading, if you are not already using clang 3.5.0 453 or higher. 454 45520190226: 456 geom_uzip(4) depends on the new module xz. If geom_uzip is statically 457 compiled into your custom kernel, add 'device xz' statement to the 458 kernel config. 459 46020190219: 461 drm and drm2 have been removed from the tree. Please see 462 https://wiki.freebsd.org/Graphics for the latest information on 463 migrating to the drm ports. 464 46520190131: 466 Iflib is no longer unconditionally compiled into the kernel. Drivers 467 using iflib and statically compiled into the kernel, now require 468 the 'device iflib' config option. For the same drivers loaded as 469 modules on kernels not having 'device iflib', the iflib.ko module 470 is loaded automatically. 471 47220190125: 473 The IEEE80211_AMPDU_AGE and AH_SUPPORT_AR5416 kernel configuration 474 options no longer exist since r343219 and r343427 respectively; 475 nothing uses them, so they should be just removed from custom 476 kernel config files. 477 47820181230: 479 r342635 changes the way efibootmgr(8) works by requiring users to add 480 the -b (bootnum) parameter for commands where the bootnum was previously 481 specified with each option. For example 'efibootmgr -B 0001' is now 482 'efibootmgr -B -b 0001'. 483 48420181220: 485 r342286 modifies the NFSv4 server so that it obeys vfs.nfsd.nfs_privport 486 in the same as it is applied to NFSv2 and 3. This implies that NFSv4 487 servers that have vfs.nfsd.nfs_privport set will only allow mounts 488 from clients using a reserved port#. Since both the FreeBSD and Linux 489 NFSv4 clients use reserved port#s by default, this should not affect 490 most NFSv4 mounts. 491 49220181219: 493 The XLP config has been removed. We can't support 64-bit atomics in this 494 kernel because it is running in 32-bit mode. XLP users must transition 495 to running a 64-bit kernel (XLP64 or XLPN32). 496 497 The mips GXEMUL support has been removed from FreeBSD. MALTA* + qemu is 498 the preferred emulator today and we don't need two different ones. 499 500 The old sibyte / swarm / Broadcom BCM1250 support has been 501 removed from the mips port. 502 50320181211: 504 Clang, llvm, lld, lldb, compiler-rt and libc++ have been upgraded to 505 7.0.1. Please see the 20141231 entry below for information about 506 prerequisites and upgrading, if you are not already using clang 3.5.0 507 or higher. 508 50920181211: 510 Remove the timed and netdate programs from the base tree. Setting 511 the time with these daemons has been obsolete for over a decade. 512 51320181126: 514 On amd64, arm64 and armv7 (architectures that install LLVM's ld.lld 515 linker as /usr/bin/ld) GNU ld is no longer installed as ld.bfd, as 516 it produces broken binaries when ifuncs are in use. Users needing 517 GNU ld should install the binutils port or package. 518 51920181123: 520 The BSD crtbegin and crtend code has been enabled by default. It has 521 had extensive testing on amd64, arm64, and i386. It can be disabled 522 by building a world with -DWITHOUT_BSD_CRTBEGIN. 523 52420181115: 525 The set of CTM commands (ctm, ctm_smail, ctm_rmail, ctm_dequeue) 526 has been converted to a port (misc/ctm) and will be removed from 527 FreeBSD-13. It is available as a package (ctm) for all supported 528 FreeBSD versions. 529 53020181110: 531 The default newsyslog.conf(5) file has been changed to only include 532 files in /etc/newsyslog.conf.d/ and /usr/local/etc/newsyslog.conf.d/ if 533 the filenames end in '.conf' and do not begin with a '.'. 534 535 You should check the configuration files in these two directories match 536 this naming convention. You can verify which configuration files are 537 being included using the command: 538 $ newsyslog -Nrv 539 54020181015: 541 Ports for the DRM modules have been simplified. Now, amd64 users should 542 just install the drm-kmod port. All others should install 543 drm-legacy-kmod. 544 545 Graphics hardware that's newer than about 2010 usually works with 546 drm-kmod. For hardware older than 2013, however, some users will need 547 to use drm-legacy-kmod if drm-kmod doesn't work for them. Hardware older 548 than 2008 usually only works in drm-legacy-kmod. The graphics team can 549 only commit to hardware made since 2013 due to the complexity of the 550 market and difficulty to test all the older cards effectively. If you 551 have hardware supported by drm-kmod, you are strongly encouraged to use 552 that as you will get better support. 553 554 Other than KPI chasing, drm-legacy-kmod will not be updated. As outlined 555 elsewhere, the drm and drm2 modules will be eliminated from the src base 556 soon (with a limited exception for arm). Please update to the package 557 asap and report any issues to x11@freebsd.org. 558 559 Generally, anybody using the drm*-kmod packages should add 560 WITHOUT_DRM_MODULE=t and WITHOUT_DRM2_MODULE=t to avoid nasty 561 cross-threading surprises, especially with automatic driver 562 loading from X11 startup. These will become the defaults in 13-current 563 shortly. 564 56520181012: 566 The ixlv(4) driver has been renamed to iavf(4). As a consequence, 567 custom kernel and module loading configuration files must be updated 568 accordingly. Moreover, interfaces previous presented as ixlvN to the 569 system are now exposed as iavfN and network configuration files must 570 be adjusted as necessary. 571 57220181009: 573 OpenSSL has been updated to version 1.1.1. This update included 574 additional various API changes throughout the base system. It is 575 important to rebuild third-party software after upgrading. The value 576 of __FreeBSD_version has been bumped accordingly. 577 57820181006: 579 The legacy DRM modules and drivers have now been added to the loader's 580 module blacklist, in favor of loading them with kld_list in rc.conf(5). 581 The module blacklist may be overridden with the loader.conf(5) 582 'module_blacklist' variable, but loading them via rc.conf(5) is strongly 583 encouraged. 584 58520181002: 586 The cam(4) based nda(4) driver will be used over nvd(4) by default on 587 powerpc64. You may set 'options NVME_USE_NVD=1' in your kernel conf or 588 loader tunable 'hw.nvme.use_nvd=1' if you wish to use the existing 589 driver. Make sure to edit /boot/etc/kboot.conf and fstab to use the 590 nda device name. 591 59220180913: 593 Reproducible build mode is now on by default, in preparation for 594 FreeBSD 12.0. This eliminates build metadata such as the user, 595 host, and time from the kernel (and uname), unless the working tree 596 corresponds to a modified checkout from a version control system. 597 The previous behavior can be obtained by setting the /etc/src.conf 598 knob WITHOUT_REPRODUCIBLE_BUILD. 599 60020180826: 601 The Yarrow CSPRNG has been removed from the kernel as it has not been 602 supported by its designers since at least 2003. Fortuna has been the 603 default since FreeBSD-11. 604 60520180822: 606 devctl freeze/thaw have gone into the tree, the rc scripts have been 607 updated to use them and devmatch has been changed. You should update 608 kernel, userland and rc scripts all at the same time. 609 61020180818: 611 The default interpreter has been switched from 4th to Lua. 612 LOADER_DEFAULT_INTERP, documented in build(7), will override the default 613 interpreter. If you have custom FORTH code you will need to set 614 LOADER_DEFAULT_INTERP=4th (valid values are 4th, lua or simp) in 615 src.conf for the build. This will create default hard links between 616 loader and loader_4th instead of loader and loader_lua, the new default. 617 If you are using UEFI it will create the proper hard link to loader.efi. 618 619 bhyve uses userboot.so. It remains 4th-only until some issues are solved 620 regarding coexisting with multiple versions of FreeBSD are resolved. 621 62220180815: 623 ls(1) now respects the COLORTERM environment variable used in other 624 systems and software to indicate that a colored terminal is both 625 supported and desired. If ls(1) is suddenly emitting colors, they may 626 be disabled again by either removing the unwanted COLORTERM from your 627 environment, or using `ls --color=never`. The ls(1) specific CLICOLOR 628 may not be observed in a future release. 629 63020180808: 631 The default pager for most commands has been changed to "less". To 632 restore the old behavior, set PAGER="more" and MANPAGER="more -s" in 633 your environment. 634 63520180731: 636 The jedec_ts(4) driver has been removed. A superset of its functionality 637 is available in the jedec_dimm(4) driver, and the manpage for that 638 driver includes migration instructions. If you have "device jedec_ts" 639 in your kernel configuration file, it must be removed. 640 64120180730: 642 amd64/GENERIC now has EFI runtime services, EFIRT, enabled by default. 643 This should have no effect if the kernel is booted via BIOS/legacy boot. 644 EFIRT may be disabled via a loader tunable, efi.rt.disabled, if a system 645 has a buggy firmware that prevents a successful boot due to use of 646 runtime services. 647 64820180727: 649 Atmel AT91RM9200 and AT91SAM9, Cavium CNS 11xx and XScale 650 support has been removed from the tree. These ports were 651 obsolete and/or known to be broken for many years. 652 65320180723: 654 loader.efi has been augmented to participate more fully in the 655 UEFI boot manager protocol. loader.efi will now look at the 656 BootXXXX environment variable to determine if a specific kernel 657 or root partition was specified. XXXX is derived from BootCurrent. 658 efibootmgr(8) manages these standard UEFI variables. 659 66020180720: 661 zfsloader's functionality has now been folded into loader. 662 zfsloader is no longer necessary once you've updated your 663 boot blocks. For a transition period, we will install a 664 hardlink for zfsloader to loader to allow a smooth transition 665 until the boot blocks can be updated (hard link because old 666 zfs boot blocks don't understand symlinks). 667 66820180719: 669 ARM64 now have efifb support, if you want to have serial console 670 on your arm64 board when an screen is connected and the bootloader 671 setup a frame buffer for us to use, just add : 672 boot_serial=YES 673 boot_multicons=YES 674 in /boot/loader.conf 675 For Raspberry Pi 3 (RPI) users, this is needed even if you don't have 676 an screen connected as the firmware will setup a frame buffer are that 677 u-boot will expose as an EFI frame buffer. 678 67920180719: 680 New uid:gid added, ntpd:ntpd (123:123). Be sure to run mergemaster 681 or take steps to update /etc/passwd before doing installworld on 682 existing systems. Do not skip the "mergemaster -Fp" step before 683 installworld, as described in the update procedures near the bottom 684 of this document. Also, rc.d/ntpd now starts ntpd(8) as user ntpd 685 if the new mac_ntpd(4) policy is available, unless ntpd_flags or 686 the ntp config file contain options that change file/dir locations. 687 When such options (e.g., "statsdir" or "crypto") are used, ntpd can 688 still be run as non-root by setting ntpd_user=ntpd in rc.conf, after 689 taking steps to ensure that all required files/dirs are accessible 690 by the ntpd user. 691 69220180717: 693 Big endian arm support has been removed. 694 69520180711: 696 The static environment setup in kernel configs is no longer mutually 697 exclusive with the loader(8) environment by default. In order to 698 restore the previous default behavior of disabling the loader(8) 699 environment if a static environment is present, you must specify 700 loader_env.disabled=1 in the static environment. 701 70220180705: 703 The ABI of syscalls used by management tools like sockstat and 704 netstat has been broken to allow 32-bit binaries to work on 705 64-bit kernels without modification. These programs will need 706 to match the kernel in order to function. External programs may 707 require minor modifications to accommodate a change of type in 708 structures from pointers to 64-bit virtual addresses. 709 71020180702: 711 On i386 and amd64 atomics are now inlined. Out of tree modules using 712 atomics will need to be rebuilt. 713 71420180701: 715 The '%I' format in the kern.corefile sysctl limits the number of 716 core files that a process can generate to the number stored in the 717 debug.ncores sysctl. The '%I' format is replaced by the single digit 718 index. Previously, if all indexes were taken the kernel would overwrite 719 only a core file with the highest index in a filename. 720 Currently the system will create a new core file if there is a free 721 index or if all slots are taken it will overwrite the oldest one. 722 72320180630: 724 Clang, llvm, lld, lldb, compiler-rt and libc++ have been upgraded to 725 6.0.1. Please see the 20141231 entry below for information about 726 prerequisites and upgrading, if you are not already using clang 3.5.0 727 or higher. 728 72920180628: 730 r335753 introduced a new quoting method. However, etc/devd/devmatch.conf 731 needed to be changed to work with it. This change was made with r335763 732 and requires a mergemaster / etcupdate / etc to update the installed 733 file. 734 73520180612: 736 r334930 changed the interface between the NFS modules, so they all 737 need to be rebuilt. r335018 did a __FreeBSD_version bump for this. 738 73920180530: 740 As of r334391 lld is the default amd64 system linker; it is installed 741 as /usr/bin/ld. Kernel build workarounds (see 20180510 entry) are no 742 longer necessary. 743 74420180530: 745 The kernel / userland interface for devinfo changed, so you'll 746 need a new kernel and userland as a pair for it to work (rebuilding 747 lib/libdevinfo is all that's required). devinfo and devmatch will 748 not work, but everything else will when there's a mismatch. 749 75020180523: 751 The on-disk format for hwpmc callchain records has changed to include 752 threadid corresponding to a given record. This changes the field offsets 753 and thus requires that libpmcstat be rebuilt before using a kernel 754 later than r334108. 755 75620180517: 757 The vxge(4) driver has been removed. This driver was introduced into 758 HEAD one week before the Exar left the Ethernet market and is not 759 known to be used. If you have device vxge in your kernel config file 760 it must be removed. 761 76220180510: 763 The amd64 kernel now requires a ld that supports ifunc to produce a 764 working kernel, either lld or a newer binutils. lld is built by default 765 on amd64, and the 'buildkernel' target uses it automatically. However, 766 it is not the default linker, so building the kernel the traditional 767 way requires LD=ld.lld on the command line (or LD=/usr/local/bin/ld for 768 binutils port/package). lld will soon be default, and this requirement 769 will go away. 770 771 NOTE: As of r334391 lld is the default system linker on amd64, and no 772 workaround is necessary. 773 77420180508: 775 The nxge(4) driver has been removed. This driver was for PCI-X 10g 776 cards made by s2io/Neterion. The company was acquired by Exar and 777 no longer sells or supports Ethernet products. If you have device 778 nxge in your kernel config file it must be removed. 779 78020180504: 781 The tz database (tzdb) has been updated to 2018e. This version more 782 correctly models time stamps in time zones with negative DST such as 783 Europe/Dublin (from 1971 on), Europe/Prague (1946/7), and 784 Africa/Windhoek (1994/2017). This does not affect the UT offsets, only 785 time zone abbreviations and the tm_isdst flag. 786 78720180502: 788 The ixgb(4) driver has been removed. This driver was for an early and 789 uncommon legacy PCI 10GbE for a single ASIC, Intel 82597EX. Intel 790 quickly shifted to the long lived ixgbe family. If you have device 791 ixgb in your kernel config file it must be removed. 792 79320180501: 794 The lmc(4) driver has been removed. This was a WAN interface 795 card that was already reportedly rare in 2003, and had an ambiguous 796 license. If you have device lmc in your kernel config file it must 797 be removed. 798 79920180413: 800 Support for Arcnet networks has been removed. If you have device 801 arcnet or device cm in your kernel config file they must be 802 removed. 803 80420180411: 805 Support for FDDI networks has been removed. If you have device 806 fddi or device fpa in your kernel config file they must be 807 removed. 808 80920180406: 810 In addition to supporting RFC 3164 formatted messages, the 811 syslogd(8) service is now capable of parsing RFC 5424 formatted 812 log messages. The main benefit of using RFC 5424 is that clients 813 may now send log messages with timestamps containing year numbers, 814 microseconds and time zone offsets. 815 816 Similarly, the syslog(3) C library function has been altered to 817 send RFC 5424 formatted messages to the local system logging 818 daemon. On systems using syslogd(8), this change should have no 819 negative impact, as long as syslogd(8) and the C library are 820 updated at the same time. On systems using a different system 821 logging daemon, it may be necessary to make configuration 822 adjustments, depending on the software used. 823 824 When using syslog-ng, add the 'syslog-protocol' flag to local 825 input sources to enable parsing of RFC 5424 formatted messages: 826 827 source src { 828 unix-dgram("/var/run/log" flags(syslog-protocol)); 829 } 830 831 When using rsyslog, disable the 'SysSock.UseSpecialParser' option 832 of the 'imuxsock' module to let messages be processed by the 833 regular RFC 3164/5424 parsing pipeline: 834 835 module(load="imuxsock" SysSock.UseSpecialParser="off") 836 837 Do note that these changes only affect communication between local 838 applications and syslogd(8). The format that syslogd(8) uses to 839 store messages on disk or forward messages to other systems 840 remains unchanged. syslogd(8) still uses RFC 3164 for these 841 purposes. Options to customize this behaviour will be added in the 842 future. Utilities that process log files stored in /var/log are 843 thus expected to continue to function as before. 844 845 __FreeBSD_version has been incremented to 1200061 to denote this 846 change. 847 84820180328: 849 Support for token ring networks has been removed. If you 850 have "device token" in your kernel config you should remove 851 it. No device drivers supported token ring. 852 85320180323: 854 makefs was modified to be able to tag ISO9660 El Torito boot catalog 855 entries as EFI instead of overloading the i386 tag as done previously. 856 The amd64 mkisoimages.sh script used to build amd64 ISO images for 857 release was updated to use this. This may mean that makefs must be 858 updated before "make cdrom" can be run in the release directory. This 859 should be as simple as: 860 861 $ cd $SRCDIR/usr.sbin/makefs 862 $ make depend all install 863 86420180212: 865 FreeBSD boot loader enhanced with Lua scripting. It's purely opt-in for 866 now by building WITH_LOADER_LUA and WITHOUT_FORTH in /etc/src.conf. 867 Co-existence for the transition period will come shortly. Booting is a 868 complex environment and test coverage for Lua-enabled loaders has been 869 thin, so it would be prudent to assume it might not work and make 870 provisions for backup boot methods. 871 87220180211: 873 devmatch functionality has been turned on in devd. It will automatically 874 load drivers for unattached devices. This may cause unexpected drivers 875 to be loaded. Please report any problems to current@ and 876 imp@freebsd.org. 877 87820180114: 879 Clang, llvm, lld, lldb, compiler-rt and libc++ have been upgraded to 880 6.0.0. Please see the 20141231 entry below for information about 881 prerequisites and upgrading, if you are not already using clang 3.5.0 882 or higher. 883 88420180110: 885 LLVM's lld linker is now used as the FreeBSD/amd64 bootstrap linker. 886 This means it is used to link the kernel and userland libraries and 887 executables, but is not yet installed as /usr/bin/ld by default. 888 889 To revert to ld.bfd as the bootstrap linker, in /etc/src.conf set 890 WITHOUT_LLD_BOOTSTRAP=yes 891 89220180110: 893 On i386, pmtimer has been removed. Its functionality has been folded 894 into apm. It was a no-op on ACPI in current for a while now (but was 895 still needed on i386 in FreeBSD 11 and earlier). Users may need to 896 remove it from kernel config files. 897 89820180104: 899 The use of RSS hash from the network card aka flowid has been 900 disabled by default for lagg(4) as it's currently incompatible with 901 the lacp and loadbalance protocols. 902 903 This can be re-enabled by setting the following in loader.conf: 904 net.link.lagg.default_use_flowid="1" 905 90620180102: 907 The SW_WATCHDOG option is no longer necessary to enable the 908 hardclock-based software watchdog if no hardware watchdog is 909 configured. As before, SW_WATCHDOG will cause the software 910 watchdog to be enabled even if a hardware watchdog is configured. 911 91220171215: 913 r326887 fixes the issue described in the 20171214 UPDATING entry. 914 r326888 flips the switch back to building GELI support always. 915 91620171214: 917 r362593 broke ZFS + GELI support for reasons unknown. However, 918 it also broke ZFS support generally, so GELI has been turned off 919 by default as the lesser evil in r326857. If you boot off ZFS and/or 920 GELI, it might not be a good time to update. 921 92220171125: 923 PowerPC users must update loader(8) by rebuilding world before 924 installing a new kernel, as the protocol connecting them has 925 changed. Without the update, loader metadata will not be passed 926 successfully to the kernel and users will have to enter their 927 root partition at the kernel mountroot prompt to continue booting. 928 Newer versions of loader can boot old kernels without issue. 929 93020171110: 931 The LOADER_FIREWIRE_SUPPORT build variable as been renamed to 932 WITH/OUT_LOADER_FIREWIRE. LOADER_{NO_,}GELI_SUPPORT has been renamed 933 to WITH/OUT_LOADER_GELI. 934 93520171106: 936 The naive and non-compliant support of posix_fallocate(2) in ZFS 937 has been removed as of r325320. The system call now returns EINVAL 938 when used on a ZFS file. Although the new behavior complies with the 939 standard, some consumers are not prepared to cope with it. 940 One known victim is lld prior to r325420. 941 94220171102: 943 Building in a FreeBSD src checkout will automatically create object 944 directories now rather than store files in the current directory if 945 'make obj' was not ran. Calling 'make obj' is no longer necessary. 946 This feature can be disabled by setting WITHOUT_AUTO_OBJ=yes in 947 /etc/src-env.conf (not /etc/src.conf), or passing the option in the 948 environment. 949 95020171101: 951 The default MAKEOBJDIR has changed from /usr/obj/<srcdir> for native 952 builds, and /usr/obj/<arch>/<srcdir> for cross-builds, to a unified 953 /usr/obj/<srcdir>/<arch>. This behavior can be changed to the old 954 format by setting WITHOUT_UNIFIED_OBJDIR=yes in /etc/src-env.conf, 955 the environment, or with -DWITHOUT_UNIFIED_OBJDIR when building. 956 The UNIFIED_OBJDIR option is a transitional feature that will be 957 removed for 12.0 release; please migrate to the new format for any 958 tools by looking up the OBJDIR used by 'make -V .OBJDIR' means rather 959 than hardcoding paths. 960 96120171028: 962 The native-xtools target no longer installs the files by default to the 963 OBJDIR. Use the native-xtools-install target with a DESTDIR to install 964 to ${DESTDIR}/${NXTP} where NXTP defaults to /nxb-bin. 965 96620171021: 967 As part of the boot loader infrastructure cleanup, LOADER_*_SUPPORT 968 options are changing from controlling the build if defined / undefined 969 to controlling the build with explicit 'yes' or 'no' values. They will 970 shift to WITH/WITHOUT options to match other options in the system. 971 97220171010: 973 libstand has turned into a private library for sys/boot use only. 974 It is no longer supported as a public interface outside of sys/boot. 975 97620171005: 977 The arm port has split armv6 into armv6 and armv7. armv7 is now 978 a valid TARGET_ARCH/MACHINE_ARCH setting. If you have an armv7 system 979 and are running a kernel from before r324363, you will need to add 980 MACHINE_ARCH=armv7 to 'make buildworld' to do a native build. 981 98220171003: 983 When building multiple kernels using KERNCONF, non-existent KERNCONF 984 files will produce an error and buildkernel will fail. Previously 985 missing KERNCONF files silently failed giving no indication as to 986 why, only to subsequently discover during installkernel that the 987 desired kernel was never built in the first place. 988 98920170912: 990 The default serial number format for CTL LUNs has changed. This will 991 affect users who use /dev/diskid/* device nodes, or whose FibreChannel 992 or iSCSI clients care about their LUNs' serial numbers. Users who 993 require serial number stability should hardcode serial numbers in 994 /etc/ctl.conf . 995 99620170912: 997 For 32-bit arm compiled for hard-float support, soft-floating point 998 binaries now always get their shared libraries from 999 LD_SOFT_LIBRARY_PATH (in the past, this was only used if 1000 /usr/libsoft also existed). Only users with a hard-float ld.so, but 1001 soft-float everything else should be affected. 1002 100320170826: 1004 The geli password typed at boot is now hidden. To restore the previous 1005 behavior, see geli(8) for configuration options. 1006 100720170825: 1008 Move PMTUD blackhole counters to TCPSTATS and remove them from bare 1009 sysctl values. Minor nit, but requires a rebuild of both world/kernel 1010 to complete. 1011 101220170814: 1013 "make check" behavior (made in ^/head@r295380) has been changed to 1014 execute from a limited sandbox, as opposed to executing from 1015 ${TESTSDIR}. 1016 1017 Behavioral changes: 1018 - The "beforecheck" and "aftercheck" targets are now specified. 1019 - ${CHECKDIR} (added in commit noted above) has been removed. 1020 - Legacy behavior can be enabled by setting 1021 WITHOUT_MAKE_CHECK_USE_SANDBOX in src.conf(5) or the environment. 1022 1023 If the limited sandbox mode is enabled, "make check" will execute 1024 "make distribution", then install, execute the tests, and clean up the 1025 sandbox if successful. 1026 1027 The "make distribution" and "make install" targets are typically run as 1028 root to set appropriate permissions and ownership at installation time. 1029 The end-user should set "WITH_INSTALL_AS_USER" in src.conf(5) or the 1030 environment if executing "make check" with limited sandbox mode using 1031 an unprivileged user. 1032 103320170808: 1034 Since the switch to GPT disk labels, fsck for UFS/FFS has been 1035 unable to automatically find alternate superblocks. As of r322297, 1036 the information needed to find alternate superblocks has been 1037 moved to the end of the area reserved for the boot block. 1038 Filesystems created with a newfs of this vintage or later 1039 will create the recovery information. If you have a filesystem 1040 created prior to this change and wish to have a recovery block 1041 created for your filesystem, you can do so by running fsck in 1042 foreground mode (i.e., do not use the -p or -y options). As it 1043 starts, fsck will ask ``SAVE DATA TO FIND ALTERNATE SUPERBLOCKS'' 1044 to which you should answer yes. 1045 104620170728: 1047 As of r321665, an NFSv4 server configuration that services 1048 Kerberos mounts or clients that do not support the uid/gid in 1049 owner/owner_group string capability, must explicitly enable 1050 the nfsuserd daemon by adding nfsuserd_enable="YES" to the 1051 machine's /etc/rc.conf file. 1052 105320170722: 1054 Clang, llvm, lldb, compiler-rt and libc++ have been upgraded to 5.0.0. 1055 Please see the 20141231 entry below for information about prerequisites 1056 and upgrading, if you are not already using clang 3.5.0 or higher. 1057 105820170701: 1059 WITHOUT_RCMDS is now the default. Set WITH_RCMDS if you need the 1060 r-commands (rlogin, rsh, etc.) to be built with the base system. 1061 106220170625: 1063 The FreeBSD/powerpc platform now uses a 64-bit type for time_t. This is 1064 a very major ABI incompatible change, so users of FreeBSD/powerpc must 1065 be careful when performing source upgrades. It is best to run 1066 'make installworld' from an alternate root system, either a live 1067 CD/memory stick, or a temporary root partition. Additionally, all ports 1068 must be recompiled. powerpc64 is largely unaffected, except in the case 1069 of 32-bit compatibility. All 32-bit binaries will be affected. 1070 107120170623: 1072 Forward compatibility for the "ino64" project have been committed. This 1073 will allow most new binaries to run on older kernels in a limited 1074 fashion. This prevents many of the common foot-shooting actions in the 1075 upgrade as well as the limited ability to roll back the kernel across 1076 the ino64 upgrade. Complicated use cases may not work properly, though 1077 enough simpler ones work to allow recovery in most situations. 1078 107920170620: 1080 Switch back to the BSDL dtc (Device Tree Compiler). Set WITH_GPL_DTC 1081 if you require the GPL compiler. 1082 108320170618: 1084 The internal ABI used for communication between the NFS kernel modules 1085 was changed by r320085, so __FreeBSD_version was bumped to 1086 ensure all the NFS related modules are updated together. 1087 108820170617: 1089 The ABI of struct event was changed by extending the data 1090 member to 64bit and adding ext fields. For upgrade, same 1091 precautions as for the entry 20170523 "ino64" must be 1092 followed. 1093 109420170531: 1095 The GNU roff toolchain has been removed from base. To render manpages 1096 which are not supported by mandoc(1), man(1) can fallback on GNU roff 1097 from ports (and recommends to install it). 1098 To render roff(7) documents, consider using GNU roff from ports or the 1099 heirloom doctools roff toolchain from ports via pkg install groff or 1100 via pkg install heirloom-doctools. 1101 110220170524: 1103 The ath(4) and ath_hal(4) modules now build piecemeal to allow for 1104 smaller runtime footprint builds. This is useful for embedded systems 1105 which only require one chipset support. 1106 1107 If you load it as a module, make sure this is in /boot/loader.conf: 1108 1109 if_ath_load="YES" 1110 1111 This will load the HAL, all chip/RF backends and if_ath_pci. 1112 If you have if_ath_pci in /boot/loader.conf, ensure it is after 1113 if_ath or it will not load any HAL chipset support. 1114 1115 If you want to selectively load things (eg on ye cheape ARM/MIPS 1116 platforms where RAM is at a premium) you should: 1117 1118 * load ath_hal 1119 * load the chip modules in question 1120 * load ath_rate, ath_dfs 1121 * load ath_main 1122 * load if_ath_pci and/or if_ath_ahb depending upon your particular 1123 bus bind type - this is where probe/attach is done. 1124 1125 For further comments/feedback, poke adrian@ . 1126 112720170523: 1128 The "ino64" 64-bit inode project has been committed, which extends 1129 a number of types to 64 bits. Upgrading in place requires care and 1130 adherence to the documented upgrade procedure. 1131 1132 If using a custom kernel configuration ensure that the 1133 COMPAT_FREEBSD11 option is included (as during the upgrade the 1134 system will be running the ino64 kernel with the existing world). 1135 1136 For the safest in-place upgrade begin by removing previous build 1137 artifacts via "rm -rf /usr/obj/*". Then, carefully follow the full 1138 procedure documented below under the heading "To rebuild everything and 1139 install it on the current system." Specifically, a reboot is required 1140 after installing the new kernel before installing world. While an 1141 installworld normally works by accident from multiuser after rebooting 1142 the proper kernel, there are many cases where this will fail across this 1143 upgrade and installworld from single user is required. 1144 114520170424: 1146 The NATM framework including the en(4), fatm(4), hatm(4), and 1147 patm(4) devices has been removed. Consumers should plan a 1148 migration before the end-of-life date for FreeBSD 11. 1149 115020170420: 1151 GNU diff has been replaced by a BSD licensed diff. Some features of GNU 1152 diff has not been implemented, if those are needed a newer version of 1153 GNU diff is available via the diffutils package under the gdiff name. 1154 115520170413: 1156 As of r316810 for ipfilter, keep frags is no longer assumed when 1157 keep state is specified in a rule. r316810 aligns ipfilter with 1158 documentation in man pages separating keep frags from keep state. 1159 This allows keep state to be specified without forcing keep frags 1160 and allows keep frags to be specified independently of keep state. 1161 To maintain previous behaviour, also specify keep frags with 1162 keep state (as documented in ipf.conf.5). 1163 116420170407: 1165 arm64 builds now use the base system LLD 4.0.0 linker by default, 1166 instead of requiring that the aarch64-binutils port or package be 1167 installed. To continue using aarch64-binutils, set 1168 CROSS_BINUTILS_PREFIX=/usr/local/aarch64-freebsd/bin . 1169 117020170405: 1171 The UDP optimization in entry 20160818 that added the sysctl 1172 net.inet.udp.require_l2_bcast has been reverted. L2 broadcast 1173 packets will no longer be treated as L3 broadcast packets. 1174 117520170331: 1176 Binds and sends to the loopback addresses, IPv6 and IPv4, will now 1177 use any explicitly assigned loopback address available in the jail 1178 instead of using the first assigned address of the jail. 1179 118020170329: 1181 The ctl.ko module no longer implements the iSCSI target frontend: 1182 cfiscsi.ko does instead. 1183 1184 If building cfiscsi.ko as a kernel module, the module can be loaded 1185 via one of the following methods: 1186 - `cfiscsi_load="YES"` in loader.conf(5). 1187 - Add `cfiscsi` to `$kld_list` in rc.conf(5). 1188 - ctladm(8)/ctld(8), when compiled with iSCSI support 1189 (`WITH_ISCSI=yes` in src.conf(5)) 1190 1191 Please see cfiscsi(4) for more details. 1192 119320170316: 1194 The mmcsd.ko module now additionally depends on geom_flashmap.ko. 1195 Also, mmc.ko and mmcsd.ko need to be a matching pair built from the 1196 same source (previously, the dependency of mmcsd.ko on mmc.ko was 1197 missing, but mmcsd.ko now will refuse to load if it is incompatible 1198 with mmc.ko). 1199 120020170315: 1201 The syntax of ipfw(8) named states was changed to avoid ambiguity. 1202 If you have used named states in the firewall rules, you need to modify 1203 them after installworld and before rebooting. Now named states must 1204 be prefixed with colon. 1205 120620170311: 1207 The old drm (sys/dev/drm/) drivers for i915 and radeon have been 1208 removed as the userland we provide cannot use them. The KMS version 1209 (sys/dev/drm2) supports the same hardware. 1210 121120170302: 1212 Clang, llvm, lldb, compiler-rt and libc++ have been upgraded to 4.0.0. 1213 Please see the 20141231 entry below for information about prerequisites 1214 and upgrading, if you are not already using clang 3.5.0 or higher. 1215 121620170221: 1217 The code that provides support for ZFS .zfs/ directory functionality 1218 has been reimplemented. It's not possible now to create a snapshot 1219 by mkdir under .zfs/snapshot/. That should be the only user visible 1220 change. 1221 122220170216: 1223 EISA bus support has been removed. The WITH_EISA option is no longer 1224 valid. 1225 122620170215: 1227 MCA bus support has been removed. 1228 122920170127: 1230 The WITH_LLD_AS_LD / WITHOUT_LLD_AS_LD build knobs have been renamed 1231 WITH_LLD_IS_LD / WITHOUT_LLD_IS_LD, for consistency with CLANG_IS_CC. 1232 123320170112: 1234 The EM_MULTIQUEUE kernel configuration option is deprecated now that 1235 the em(4) driver conforms to iflib specifications. 1236 123720170109: 1238 The igb(4), em(4) and lem(4) ethernet drivers are now implemented via 1239 IFLIB. If you have a custom kernel configuration that excludes em(4) 1240 but you use igb(4), you need to re-add em(4) to your custom 1241 configuration. 1242 124320161217: 1244 Clang, llvm, lldb, compiler-rt and libc++ have been upgraded to 3.9.1. 1245 Please see the 20141231 entry below for information about prerequisites 1246 and upgrading, if you are not already using clang 3.5.0 or higher. 1247 124820161124: 1249 Clang, llvm, lldb, compiler-rt and libc++ have been upgraded to 3.9.0. 1250 Please see the 20141231 entry below for information about prerequisites 1251 and upgrading, if you are not already using clang 3.5.0 or higher. 1252 125320161119: 1254 The layout of the pmap structure has changed for powerpc to put the pmap 1255 statistics at the front for all CPU variations. libkvm(3) and all tools 1256 that link against it need to be recompiled. 1257 125820161030: 1259 isl(4) and cyapa(4) drivers now require a new driver, 1260 chromebook_platform(4), to work properly on Chromebook-class hardware. 1261 On other types of hardware the drivers may need to be configured using 1262 device hints. Please see the corresponding manual pages for details. 1263 126420161017: 1265 The urtwn(4) driver was merged into rtwn(4) and now consists of 1266 rtwn(4) main module + rtwn_usb(4) and rtwn_pci(4) bus-specific 1267 parts. 1268 Also, firmware for RTL8188CE was renamed due to possible name 1269 conflict (rtwnrtl8192cU(B) -> rtwnrtl8192cE(B)) 1270 127120161015: 1272 GNU rcs has been removed from base. It is available as packages: 1273 - rcs: Latest GPLv3 GNU rcs version. 1274 - rcs57: Copy of the latest version of GNU rcs (GPLv2) before it was 1275 removed from base. 1276 127720161008: 1278 Use of the cc_cdg, cc_chd, cc_hd, or cc_vegas congestion control 1279 modules now requires that the kernel configuration contain the 1280 TCP_HHOOK option. (This option is included in the GENERIC kernel.) 1281 128220161003: 1283 The WITHOUT_ELFCOPY_AS_OBJCOPY src.conf(5) knob has been retired. 1284 ELF Tool Chain's elfcopy is always installed as /usr/bin/objcopy. 1285 128620160924: 1287 Relocatable object files with the extension of .So have been renamed 1288 to use an extension of .pico instead. The purpose of this change is 1289 to avoid a name clash with shared libraries on case-insensitive file 1290 systems. On those file systems, foo.So is the same file as foo.so. 1291 129220160918: 1293 GNU rcs has been turned off by default. It can (temporarily) be built 1294 again by adding WITH_RCS knob in src.conf. 1295 Otherwise, GNU rcs is available from packages: 1296 - rcs: Latest GPLv3 GNU rcs version. 1297 - rcs57: Copy of the latest version of GNU rcs (GPLv2) from base. 1298 129920160918: 1300 The backup_uses_rcs functionality has been removed from rc.subr. 1301 130220160908: 1303 The queue(3) debugging macro, QUEUE_MACRO_DEBUG, has been split into 1304 two separate components, QUEUE_MACRO_DEBUG_TRACE and 1305 QUEUE_MACRO_DEBUG_TRASH. Define both for the original 1306 QUEUE_MACRO_DEBUG behavior. 1307 130820160824: 1309 r304787 changed some ioctl interfaces between the iSCSI userspace 1310 programs and the kernel. ctladm, ctld, iscsictl, and iscsid must be 1311 rebuilt to work with new kernels. __FreeBSD_version has been bumped 1312 to 1200005. 1313 131420160818: 1315 The UDP receive code has been updated to only treat incoming UDP 1316 packets that were addressed to an L2 broadcast address as L3 1317 broadcast packets. It is not expected that this will affect any 1318 standards-conforming UDP application. The new behaviour can be 1319 disabled by setting the sysctl net.inet.udp.require_l2_bcast to 1320 0. 1321 132220160818: 1323 Remove the openbsd_poll system call. 1324 __FreeBSD_version has been bumped because of this. 1325 132620160708: 1327 The stable/11 branch has been created from head@r302406. 1328 132920160622: 1330 The libc stub for the pipe(2) system call has been replaced with 1331 a wrapper that calls the pipe2(2) system call and the pipe(2) 1332 system call is now only implemented by the kernels that include 1333 "options COMPAT_FREEBSD10" in their config file (this is the 1334 default). Users should ensure that this option is enabled in 1335 their kernel or upgrade userspace to r302092 before upgrading their 1336 kernel. 1337 133820160527: 1339 CAM will now strip leading spaces from SCSI disks' serial numbers. 1340 This will affect users who create UFS filesystems on SCSI disks using 1341 those disk's diskid device nodes. For example, if /etc/fstab 1342 previously contained a line like 1343 "/dev/diskid/DISK-%20%20%20%20%20%20%20ABCDEFG0123456", you should 1344 change it to "/dev/diskid/DISK-ABCDEFG0123456". Users of geom 1345 transforms like gmirror may also be affected. ZFS users should 1346 generally be fine. 1347 134820160523: 1349 The bitstring(3) API has been updated with new functionality and 1350 improved performance. But it is binary-incompatible with the old API. 1351 Objects built with the new headers may not be linked against objects 1352 built with the old headers. 1353 135420160520: 1355 The brk and sbrk functions have been removed from libc on arm64. 1356 Binutils from ports has been updated to not link to these 1357 functions and should be updated to the latest version before 1358 installing a new libc. 1359 136020160517: 1361 The armv6 port now defaults to hard float ABI. Limited support 1362 for running both hardfloat and soft float on the same system 1363 is available using the libraries installed with -DWITH_LIBSOFT. 1364 This has only been tested as an upgrade path for installworld 1365 and packages may fail or need manual intervention to run. New 1366 packages will be needed. 1367 1368 To update an existing self-hosted armv6hf system, you must add 1369 TARGET_ARCH=armv6 on the make command line for both the build 1370 and the install steps. 1371 137220160510: 1373 Kernel modules compiled outside of a kernel build now default to 1374 installing to /boot/modules instead of /boot/kernel. Many kernel 1375 modules built this way (such as those in ports) already overrode 1376 KMODDIR explicitly to install into /boot/modules. However, 1377 manually building and installing a module from /sys/modules will 1378 now install to /boot/modules instead of /boot/kernel. 1379 138020160414: 1381 The CAM I/O scheduler has been committed to the kernel. There should be 1382 no user visible impact. This does enable NCQ Trim on ada SSDs. While the 1383 list of known rogues that claim support for this but actually corrupt 1384 data is believed to be complete, be on the lookout for data 1385 corruption. The known rogue list is believed to be complete: 1386 1387 o Crucial MX100, M550 drives with MU01 firmware. 1388 o Micron M510 and M550 drives with MU01 firmware. 1389 o Micron M500 prior to MU07 firmware 1390 o Samsung 830, 840, and 850 all firmwares 1391 o FCCT M500 all firmwares 1392 1393 Crucial has firmware http://www.crucial.com/usa/en/support-ssd-firmware 1394 with working NCQ TRIM. For Micron branded drives, see your sales rep for 1395 updated firmware. Black listed drives will work correctly because these 1396 drives work correctly so long as no NCQ TRIMs are sent to them. Given 1397 this list is the same as found in Linux, it's believed there are no 1398 other rogues in the market place. All other models from the above 1399 vendors work. 1400 1401 To be safe, if you are at all concerned, you can quirk each of your 1402 drives to prevent NCQ from being sent by setting: 1403 kern.cam.ada.X.quirks="0x2" 1404 in loader.conf. If the drive requires the 4k sector quirk, set the 1405 quirks entry to 0x3. 1406 140720160330: 1408 The FAST_DEPEND build option has been removed and its functionality is 1409 now the one true way. The old mkdep(1) style of 'make depend' has 1410 been removed. See 20160311 for further details. 1411 141220160317: 1413 Resource range types have grown from unsigned long to uintmax_t. All 1414 drivers, and anything using libdevinfo, need to be recompiled. 1415 141620160311: 1417 WITH_FAST_DEPEND is now enabled by default for in-tree and out-of-tree 1418 builds. It no longer runs mkdep(1) during 'make depend', and the 1419 'make depend' stage can safely be skipped now as it is auto ran 1420 when building 'make all' and will generate all SRCS and DPSRCS before 1421 building anything else. Dependencies are gathered at compile time with 1422 -MF flags kept in separate .depend files per object file. Users should 1423 run 'make cleandepend' once if using -DNO_CLEAN to clean out older 1424 stale .depend files. 1425 142620160306: 1427 On amd64, clang 3.8.0 can now insert sections of type AMD64_UNWIND into 1428 kernel modules. Therefore, if you load any kernel modules at boot time, 1429 please install the boot loaders after you install the kernel, but before 1430 rebooting, e.g.: 1431 1432 make buildworld 1433 make buildkernel KERNCONF=YOUR_KERNEL_HERE 1434 make installkernel KERNCONF=YOUR_KERNEL_HERE 1435 make -C sys/boot install 1436 <reboot in single user> 1437 1438 Then follow the usual steps, described in the General Notes section, 1439 below. 1440 144120160305: 1442 Clang, llvm, lldb and compiler-rt have been upgraded to 3.8.0. Please 1443 see the 20141231 entry below for information about prerequisites and 1444 upgrading, if you are not already using clang 3.5.0 or higher. 1445 144620160301: 1447 The AIO subsystem is now a standard part of the kernel. The 1448 VFS_AIO kernel option and aio.ko kernel module have been removed. 1449 Due to stability concerns, asynchronous I/O requests are only 1450 permitted on sockets and raw disks by default. To enable 1451 asynchronous I/O requests on all file types, set the 1452 vfs.aio.enable_unsafe sysctl to a non-zero value. 1453 145420160226: 1455 The ELF object manipulation tool objcopy is now provided by the 1456 ELF Tool Chain project rather than by GNU binutils. It should be a 1457 drop-in replacement, with the addition of arm64 support. The 1458 (temporary) src.conf knob WITHOUT_ELFCOPY_AS_OBJCOPY knob may be set 1459 to obtain the GNU version if necessary. 1460 146120160129: 1462 Building ZFS pools on top of zvols is prohibited by default. That 1463 feature has never worked safely; it's always been prone to deadlocks. 1464 Using a zvol as the backing store for a VM guest's virtual disk will 1465 still work, even if the guest is using ZFS. Legacy behavior can be 1466 restored by setting vfs.zfs.vol.recursive=1. 1467 146820160119: 1469 The NONE and HPN patches has been removed from OpenSSH. They are 1470 still available in the security/openssh-portable port. 1471 147220160113: 1473 With the addition of ypldap(8), a new _ypldap user is now required 1474 during installworld. "mergemaster -p" can be used to add the user 1475 prior to installworld, as documented in the handbook. 1476 147720151216: 1478 The tftp loader (pxeboot) now uses the option root-path directive. As a 1479 consequence it no longer looks for a pxeboot.4th file on the tftp 1480 server. Instead it uses the regular /boot infrastructure as with the 1481 other loaders. 1482 148320151211: 1484 The code to start recording plug and play data into the modules has 1485 been committed. While the old tools will properly build a new kernel, 1486 a number of warnings about "unknown metadata record 4" will be produced 1487 for an older kldxref. To avoid such warnings, make sure to rebuild 1488 the kernel toolchain (or world). Make sure that you have r292078 or 1489 later when trying to build 292077 or later before rebuilding. 1490 149120151207: 1492 Debug data files are now built by default with 'make buildworld' and 1493 installed with 'make installworld'. This facilitates debugging but 1494 requires more disk space both during the build and for the installed 1495 world. Debug files may be disabled by setting WITHOUT_DEBUG_FILES=yes 1496 in src.conf(5). 1497 149820151130: 1499 r291527 changed the internal interface between the nfsd.ko and 1500 nfscommon.ko modules. As such, they must both be upgraded to-gether. 1501 __FreeBSD_version has been bumped because of this. 1502 150320151108: 1504 Add support for unicode collation strings leads to a change of 1505 order of files listed by ls(1) for example. To get back to the old 1506 behaviour, set LC_COLLATE environment variable to "C". 1507 1508 Databases administrators will need to reindex their databases given 1509 collation results will be different. 1510 1511 Due to a bug in install(1) it is recommended to remove the ancient 1512 locales before running make installworld. 1513 1514 rm -rf /usr/share/locale/* 1515 151620151030: 1517 The OpenSSL has been upgraded to 1.0.2d. Any binaries requiring 1518 libcrypto.so.7 or libssl.so.7 must be recompiled. 1519 152020151020: 1521 Qlogic 24xx/25xx firmware images were updated from 5.5.0 to 7.3.0. 1522 Kernel modules isp_2400_multi and isp_2500_multi were removed and 1523 should be replaced with isp_2400 and isp_2500 modules respectively. 1524 152520151017: 1526 The build previously allowed using 'make -n' to not recurse into 1527 sub-directories while showing what commands would be executed, and 1528 'make -n -n' to recursively show commands. Now 'make -n' will recurse 1529 and 'make -N' will not. 1530 153120151012: 1532 If you specify SENDMAIL_MC or SENDMAIL_CF in make.conf, mergemaster 1533 and etcupdate will now use this file. A custom sendmail.cf is now 1534 updated via this mechanism rather than via installworld. If you had 1535 excluded sendmail.cf in mergemaster.rc or etcupdate.conf, you may 1536 want to remove the exclusion or change it to "always install". 1537 /etc/mail/sendmail.cf is now managed the same way regardless of 1538 whether SENDMAIL_MC/SENDMAIL_CF is used. If you are not using 1539 SENDMAIL_MC/SENDMAIL_CF there should be no change in behavior. 1540 154120151011: 1542 Compatibility shims for legacy ATA device names have been removed. 1543 It includes ATA_STATIC_ID kernel option, kern.cam.ada.legacy_aliases 1544 and kern.geom.raid.legacy_aliases loader tunables, kern.devalias.* 1545 environment variables, /dev/ad* and /dev/ar* symbolic links. 1546 154720151006: 1548 Clang, llvm, lldb, compiler-rt and libc++ have been upgraded to 3.7.0. 1549 Please see the 20141231 entry below for information about prerequisites 1550 and upgrading, if you are not already using clang 3.5.0 or higher. 1551 155220150924: 1553 Kernel debug files have been moved to /usr/lib/debug/boot/kernel/, 1554 and renamed from .symbols to .debug. This reduces the size requirements 1555 on the boot partition or file system and provides consistency with 1556 userland debug files. 1557 1558 When using the supported kernel installation method the 1559 /usr/lib/debug/boot/kernel directory will be renamed (to kernel.old) 1560 as is done with /boot/kernel. 1561 1562 Developers wishing to maintain the historical behavior of installing 1563 debug files in /boot/kernel/ can set KERN_DEBUGDIR="" in src.conf(5). 1564 156520150827: 1566 The wireless drivers had undergone changes that remove the 'parent 1567 interface' from the ifconfig -l output. The rc.d network scripts 1568 used to check presence of a parent interface in the list, so old 1569 scripts would fail to start wireless networking. Thus, etcupdate(3) 1570 or mergemaster(8) run is required after kernel update, to update your 1571 rc.d scripts in /etc. 1572 157320150827: 1574 pf no longer supports 'scrub fragment crop' or 'scrub fragment drop-ovl' 1575 These configurations are now automatically interpreted as 1576 'scrub fragment reassemble'. 1577 157820150817: 1579 Kernel-loadable modules for the random(4) device are back. To use 1580 them, the kernel must have 1581 1582 device random 1583 options RANDOM_LOADABLE 1584 1585 kldload(8) can then be used to load random_fortuna.ko 1586 or random_yarrow.ko. Please note that due to the indirect 1587 function calls that the loadable modules need to provide, 1588 the build-in variants will be slightly more efficient. 1589 1590 The random(4) kernel option RANDOM_DUMMY has been retired due to 1591 unpopularity. It was not all that useful anyway. 1592 159320150813: 1594 The WITHOUT_ELFTOOLCHAIN_TOOLS src.conf(5) knob has been retired. 1595 Control over building the ELF Tool Chain tools is now provided by 1596 the WITHOUT_TOOLCHAIN knob. 1597 159820150810: 1599 The polarity of Pulse Per Second (PPS) capture events with the 1600 uart(4) driver has been corrected. Prior to this change the PPS 1601 "assert" event corresponded to the trailing edge of a positive PPS 1602 pulse and the "clear" event was the leading edge of the next pulse. 1603 1604 As the width of a PPS pulse in a typical GPS receiver is on the 1605 order of 1 millisecond, most users will not notice any significant 1606 difference with this change. 1607 1608 Anyone who has compensated for the historical polarity reversal by 1609 configuring a negative offset equal to the pulse width will need to 1610 remove that workaround. 1611 161220150809: 1613 The default group assigned to /dev/dri entries has been changed 1614 from 'wheel' to 'video' with the id of '44'. If you want to have 1615 access to the dri devices please add yourself to the video group 1616 with: 1617 1618 # pw groupmod video -m $USER 1619 162020150806: 1621 The menu.rc and loader.rc files will now be replaced during 1622 upgrades. Please migrate local changes to menu.rc.local and 1623 loader.rc.local instead. 1624 162520150805: 1626 GNU Binutils versions of addr2line, c++filt, nm, readelf, size, 1627 strings and strip have been removed. The src.conf(5) knob 1628 WITHOUT_ELFTOOLCHAIN_TOOLS no longer provides the binutils tools. 1629 163020150728: 1631 As ZFS requires more kernel stack pages than is the default on some 1632 architectures e.g. i386, it now warns if KSTACK_PAGES is less than 1633 ZFS_MIN_KSTACK_PAGES (which is 4 at the time of writing). 1634 1635 Please consider using 'options KSTACK_PAGES=X' where X is greater 1636 than or equal to ZFS_MIN_KSTACK_PAGES i.e. 4 in such configurations. 1637 163820150706: 1639 sendmail has been updated to 8.15.2. Starting with FreeBSD 11.0 1640 and sendmail 8.15, sendmail uses uncompressed IPv6 addresses by 1641 default, i.e., they will not contain "::". For example, instead 1642 of ::1, it will be 0:0:0:0:0:0:0:1. This permits a zero subnet 1643 to have a more specific match, such as different map entries for 1644 IPv6:0:0 vs IPv6:0. This change requires that configuration 1645 data (including maps, files, classes, custom ruleset, etc.) must 1646 use the same format, so make certain such configuration data is 1647 upgrading. As a very simple check search for patterns like 1648 'IPv6:[0-9a-fA-F:]*::' and 'IPv6::'. To return to the old 1649 behavior, set the m4 option confUSE_COMPRESSED_IPV6_ADDRESSES or 1650 the cf option UseCompressedIPv6Addresses. 1651 165220150630: 1653 The default kernel entropy-processing algorithm is now 1654 Fortuna, replacing Yarrow. 1655 1656 Assuming you have 'device random' in your kernel config 1657 file, the configurations allow a kernel option to override 1658 this default. You may choose *ONE* of: 1659 1660 options RANDOM_YARROW # Legacy /dev/random algorithm. 1661 options RANDOM_DUMMY # Blocking-only driver. 1662 1663 If you have neither, you get Fortuna. For most people, 1664 read no further, Fortuna will give a /dev/random that works 1665 like it always used to, and the difference will be irrelevant. 1666 1667 If you remove 'device random', you get *NO* kernel-processed 1668 entropy at all. This may be acceptable to folks building 1669 embedded systems, but has complications. Carry on reading, 1670 and it is assumed you know what you need. 1671 1672 *PLEASE* read random(4) and random(9) if you are in the 1673 habit of tweaking kernel configs, and/or if you are a member 1674 of the embedded community, wanting specific and not-usual 1675 behaviour from your security subsystems. 1676 1677 NOTE!! If you use RANDOM_DUMMY and/or have no 'device 1678 random', you will NOT have a functioning /dev/random, and 1679 many cryptographic features will not work, including SSH. 1680 You may also find strange behaviour from the random(3) set 1681 of library functions, in particular sranddev(3), srandomdev(3) 1682 and arc4random(3). The reason for this is that the KERN_ARND 1683 sysctl only returns entropy if it thinks it has some to 1684 share, and with RANDOM_DUMMY or no 'device random' this 1685 will never happen. 1686 168720150623: 1688 An additional fix for the issue described in the 20150614 sendmail 1689 entry below has been committed in revision 284717. 1690 169120150616: 1692 FreeBSD's old make (fmake) has been removed from the system. It is 1693 available as the devel/fmake port or via pkg install fmake. 1694 169520150615: 1696 The fix for the issue described in the 20150614 sendmail entry 1697 below has been committed in revision 284436. The work 1698 around described in that entry is no longer needed unless the 1699 default setting is overridden by a confDH_PARAMETERS configuration 1700 setting of '5' or pointing to a 512 bit DH parameter file. 1701 170220150614: 1703 ALLOW_DEPRECATED_ATF_TOOLS/ATFFILE support has been removed from 1704 atf.test.mk (included from bsd.test.mk). Please upgrade devel/atf 1705 and devel/kyua to version 0.20+ and adjust any calling code to work 1706 with Kyuafile and kyua. 1707 170820150614: 1709 The import of openssl to address the FreeBSD-SA-15:10.openssl 1710 security advisory includes a change which rejects handshakes 1711 with DH parameters below 768 bits. sendmail releases prior 1712 to 8.15.2 (not yet released), defaulted to a 512 bit 1713 DH parameter setting for client connections. To work around 1714 this interoperability, sendmail can be configured to use a 1715 2048 bit DH parameter by: 1716 1717 1. Edit /etc/mail/`hostname`.mc 1718 2. If a setting for confDH_PARAMETERS does not exist or 1719 exists and is set to a string beginning with '5', 1720 replace it with '2'. 1721 3. If a setting for confDH_PARAMETERS exists and is set to 1722 a file path, create a new file with: 1723 openssl dhparam -out /path/to/file 2048 1724 4. Rebuild the .cf file: 1725 cd /etc/mail/; make; make install 1726 5. Restart sendmail: 1727 cd /etc/mail/; make restart 1728 1729 A sendmail patch is coming, at which time this file will be 1730 updated. 1731 173220150604: 1733 Generation of legacy formatted entries have been disabled by default 1734 in pwd_mkdb(8), as all base system consumers of the legacy formatted 1735 entries were converted to use the new format by default when the new, 1736 machine independent format have been added and supported since FreeBSD 1737 5.x. 1738 1739 Please see the pwd_mkdb(8) manual page for further details. 1740 174120150525: 1742 Clang and llvm have been upgraded to 3.6.1 release. Please see the 1743 20141231 entry below for information about prerequisites and upgrading, 1744 if you are not already using 3.5.0 or higher. 1745 174620150521: 1747 TI platform code switched to using vendor DTS files and this update 1748 may break existing systems running on Beaglebone, Beaglebone Black, 1749 and Pandaboard: 1750 1751 - dtb files should be regenerated/reinstalled. Filenames are the 1752 same but content is different now 1753 - GPIO addressing was changed, now each GPIO bank (32 pins per bank) 1754 has its own /dev/gpiocX device, e.g. pin 121 on /dev/gpioc0 in old 1755 addressing scheme is now pin 25 on /dev/gpioc3. 1756 - Pandaboard: /etc/ttys should be updated, serial console device is 1757 now /dev/ttyu2, not /dev/ttyu0 1758 175920150501: 1760 soelim(1) from gnu/usr.bin/groff has been replaced by usr.bin/soelim. 1761 If you need the GNU extension from groff soelim(1), install groff 1762 from package: pkg install groff, or via ports: textproc/groff. 1763 176420150423: 1765 chmod, chflags, chown and chgrp now affect symlinks in -R mode as 1766 defined in symlink(7); previously symlinks were silently ignored. 1767 176820150415: 1769 The const qualifier has been removed from iconv(3) to comply with 1770 POSIX. The ports tree is aware of this from r384038 onwards. 1771 177220150416: 1773 Libraries specified by LIBADD in Makefiles must have a corresponding 1774 DPADD_<lib> variable to ensure correct dependencies. This is now 1775 enforced in src.libnames.mk. 1776 177720150324: 1778 From legacy ata(4) driver was removed support for SATA controllers 1779 supported by more functional drivers ahci(4), siis(4) and mvs(4). 1780 Kernel modules ataahci and ataadaptec were removed completely, 1781 replaced by ahci and mvs modules respectively. 1782 178320150315: 1784 Clang, llvm and lldb have been upgraded to 3.6.0 release. Please see 1785 the 20141231 entry below for information about prerequisites and 1786 upgrading, if you are not already using 3.5.0 or higher. 1787 178820150307: 1789 The 32-bit PowerPC kernel has been changed to a position-independent 1790 executable. This can only be booted with a version of loader(8) 1791 newer than January 31, 2015, so make sure to update both world and 1792 kernel before rebooting. 1793 179420150217: 1795 If you are running a -CURRENT kernel since r273872 (Oct 30th, 2014), 1796 but before r278950, the RNG was not seeded properly. Immediately 1797 upgrade the kernel to r278950 or later and regenerate any keys (e.g. 1798 ssh keys or openssl keys) that were generated w/ a kernel from that 1799 range. This does not affect programs that directly used /dev/random 1800 or /dev/urandom. All userland uses of arc4random(3) are affected. 1801 180220150210: 1803 The autofs(4) ABI was changed in order to restore binary compatibility 1804 with 10.1-RELEASE. The automountd(8) daemon needs to be rebuilt to work 1805 with the new kernel. 1806 180720150131: 1808 The powerpc64 kernel has been changed to a position-independent 1809 executable. This can only be booted with a new version of loader(8), 1810 so make sure to update both world and kernel before rebooting. 1811 181220150118: 1813 Clang and llvm have been upgraded to 3.5.1 release. This is a bugfix 1814 only release, no new features have been added. Please see the 20141231 1815 entry below for information about prerequisites and upgrading, if you 1816 are not already using 3.5.0. 1817 181820150107: 1819 ELF tools addr2line, elfcopy (strip), nm, size, and strings are now 1820 taken from the ELF Tool Chain project rather than GNU binutils. They 1821 should be drop-in replacements, with the addition of arm64 support. 1822 The WITHOUT_ELFTOOLCHAIN_TOOLS= knob may be used to obtain the 1823 binutils tools, if necessary. See 20150805 for updated information. 1824 182520150105: 1826 The default Unbound configuration now enables remote control 1827 using a local socket. Users who have already enabled the 1828 local_unbound service should regenerate their configuration 1829 by running "service local_unbound setup" as root. 1830 183120150102: 1832 The GNU texinfo and GNU info pages have been removed. 1833 To be able to view GNU info pages please install texinfo from ports. 1834 183520141231: 1836 Clang, llvm and lldb have been upgraded to 3.5.0 release. 1837 1838 As of this release, a prerequisite for building clang, llvm and lldb is 1839 a C++11 capable compiler and C++11 standard library. This means that to 1840 be able to successfully build the cross-tools stage of buildworld, with 1841 clang as the bootstrap compiler, your system compiler or cross compiler 1842 should either be clang 3.3 or later, or gcc 4.8 or later, and your 1843 system C++ library should be libc++, or libdstdc++ from gcc 4.8 or 1844 later. 1845 1846 On any standard FreeBSD 10.x or 11.x installation, where clang and 1847 libc++ are on by default (that is, on x86 or arm), this should work out 1848 of the box. 1849 1850 On 9.x installations where clang is enabled by default, e.g. on x86 and 1851 powerpc, libc++ will not be enabled by default, so libc++ should be 1852 built (with clang) and installed first. If both clang and libc++ are 1853 missing, build clang first, then use it to build libc++. 1854 1855 On 8.x and earlier installations, upgrade to 9.x first, and then follow 1856 the instructions for 9.x above. 1857 1858 Sparc64 and mips users are unaffected, as they still use gcc 4.2.1 by 1859 default, and do not build clang. 1860 1861 Many embedded systems are resource constrained, and will not be able to 1862 build clang in a reasonable time, or in some cases at all. In those 1863 cases, cross building bootable systems on amd64 is a workaround. 1864 1865 This new version of clang introduces a number of new warnings, of which 1866 the following are most likely to appear: 1867 1868 -Wabsolute-value 1869 1870 This warns in two cases, for both C and C++: 1871 * When the code is trying to take the absolute value of an unsigned 1872 quantity, which is effectively a no-op, and almost never what was 1873 intended. The code should be fixed, if at all possible. If you are 1874 sure that the unsigned quantity can be safely cast to signed, without 1875 loss of information or undefined behavior, you can add an explicit 1876 cast, or disable the warning. 1877 1878 * When the code is trying to take an absolute value, but the called 1879 abs() variant is for the wrong type, which can lead to truncation. 1880 If you want to disable the warning instead of fixing the code, please 1881 make sure that truncation will not occur, or it might lead to unwanted 1882 side-effects. 1883 1884 -Wtautological-undefined-compare and 1885 -Wundefined-bool-conversion 1886 1887 These warn when C++ code is trying to compare 'this' against NULL, while 1888 'this' should never be NULL in well-defined C++ code. However, there is 1889 some legacy (pre C++11) code out there, which actively abuses this 1890 feature, which was less strictly defined in previous C++ versions. 1891 1892 Squid and openjdk do this, for example. The warning can be turned off 1893 for C++98 and earlier, but compiling the code in C++11 mode might result 1894 in unexpected behavior; for example, the parts of the program that are 1895 unreachable could be optimized away. 1896 189720141222: 1898 The old NFS client and server (kernel options NFSCLIENT, NFSSERVER) 1899 kernel sources have been removed. The .h files remain, since some 1900 utilities include them. This will need to be fixed later. 1901 If "mount -t oldnfs ..." is attempted, it will fail. 1902 If the "-o" option on mountd(8), nfsd(8) or nfsstat(1) is used, 1903 the utilities will report errors. 1904 190520141121: 1906 The handling of LOCAL_LIB_DIRS has been altered to skip addition of 1907 directories to top level SUBDIR variable when their parent 1908 directory is included in LOCAL_DIRS. Users with build systems with 1909 such hierarchies and without SUBDIR entries in the parent 1910 directory Makefiles should add them or add the directories to 1911 LOCAL_DIRS. 1912 191320141109: 1914 faith(4) and faithd(8) have been removed from the base system. Faith 1915 has been obsolete for a very long time. 1916 191720141104: 1918 vt(4), the new console driver, is enabled by default. It brings 1919 support for Unicode and double-width characters, as well as 1920 support for UEFI and integration with the KMS kernel video 1921 drivers. 1922 1923 You may need to update your console settings in /etc/rc.conf, 1924 most probably the keymap. During boot, /etc/rc.d/syscons will 1925 indicate what you need to do. 1926 1927 vt(4) still has issues and lacks some features compared to 1928 syscons(4). See the wiki for up-to-date information: 1929 https://wiki.freebsd.org/Newcons 1930 1931 If you want to keep using syscons(4), you can do so by adding 1932 the following line to /boot/loader.conf: 1933 kern.vty=sc 1934 193520141102: 1936 pjdfstest has been integrated into kyua as an opt-in test suite. 1937 Please see share/doc/pjdfstest/README for more details on how to 1938 execute it. 1939 194020141009: 1941 gperf has been removed from the base system for architectures 1942 that use clang. Ports that require gperf will obtain it from the 1943 devel/gperf port. 1944 194520140923: 1946 pjdfstest has been moved from tools/regression/pjdfstest to 1947 contrib/pjdfstest . 1948 194920140922: 1950 At svn r271982, The default linux compat kernel ABI has been adjusted 1951 to 2.6.18 in support of the linux-c6 compat ports infrastructure 1952 update. If you wish to continue using the linux-f10 compat ports, 1953 add compat.linux.osrelease=2.6.16 to your local sysctl.conf. Users are 1954 encouraged to update their linux-compat packages to linux-c6 during 1955 their next update cycle. 1956 195720140729: 1958 The ofwfb driver, used to provide a graphics console on PowerPC when 1959 using vt(4), no longer allows mmap() of all physical memory. This 1960 will prevent Xorg on PowerPC with some ATI graphics cards from 1961 initializing properly unless x11-servers/xorg-server is updated to 1962 1.12.4_8 or newer. 1963 196420140723: 1965 The xdev targets have been converted to using TARGET and 1966 TARGET_ARCH instead of XDEV and XDEV_ARCH. 1967 196820140719: 1969 The default unbound configuration has been modified to address 1970 issues with reverse lookups on networks that use private 1971 address ranges. If you use the local_unbound service, run 1972 "service local_unbound setup" as root to regenerate your 1973 configuration, then "service local_unbound reload" to load the 1974 new configuration. 1975 197620140709: 1977 The GNU texinfo and GNU info pages are not built and installed 1978 anymore, WITH_INFO knob has been added to allow to built and install 1979 them again. 1980 UPDATE: see 20150102 entry on texinfo's removal 1981 198220140708: 1983 The GNU readline library is now an INTERNALLIB - that is, it is 1984 statically linked into consumers (GDB and variants) in the base 1985 system, and the shared library is no longer installed. The 1986 devel/readline port is available for third party software that 1987 requires readline. 1988 198920140702: 1990 The Itanium architecture (ia64) has been removed from the list of 1991 known architectures. This is the first step in the removal of the 1992 architecture. 1993 199420140701: 1995 Commit r268115 has added NFSv4.1 server support, merged from 1996 projects/nfsv4.1-server. Since this includes changes to the 1997 internal interfaces between the NFS related modules, a full 1998 build of the kernel and modules will be necessary. 1999 __FreeBSD_version has been bumped. 2000 200120140629: 2002 The WITHOUT_VT_SUPPORT kernel config knob has been renamed 2003 WITHOUT_VT. (The other _SUPPORT knobs have a consistent meaning 2004 which differs from the behaviour controlled by this knob.) 2005 200620140619: 2007 Maximal length of the serial number in CTL was increased from 16 to 2008 64 chars, that breaks ABI. All CTL-related tools, such as ctladm 2009 and ctld, need to be rebuilt to work with a new kernel. 2010 201120140606: 2012 The libatf-c and libatf-c++ major versions were downgraded to 0 and 2013 1 respectively to match the upstream numbers. They were out of 2014 sync because, when they were originally added to FreeBSD, the 2015 upstream versions were not respected. These libraries are private 2016 and not yet built by default, so renumbering them should be a 2017 non-issue. However, unclean source trees will yield broken test 2018 programs once the operator executes "make delete-old-libs" after a 2019 "make installworld". 2020 2021 Additionally, the atf-sh binary was made private by moving it into 2022 /usr/libexec/. Already-built shell test programs will keep the 2023 path to the old binary so they will break after "make delete-old" 2024 is run. 2025 2026 If you are using WITH_TESTS=yes (not the default), wipe the object 2027 tree and rebuild from scratch to prevent spurious test failures. 2028 This is only needed once: the misnumbered libraries and misplaced 2029 binaries have been added to OptionalObsoleteFiles.inc so they will 2030 be removed during a clean upgrade. 2031 203220140512: 2033 Clang and llvm have been upgraded to 3.4.1 release. 2034 203520140508: 2036 We bogusly installed src.opts.mk in /usr/share/mk. This file should 2037 be removed to avoid issues in the future (and has been added to 2038 ObsoleteFiles.inc). 2039 204020140505: 2041 /etc/src.conf now affects only builds of the FreeBSD src tree. In the 2042 past, it affected all builds that used the bsd.*.mk files. The old 2043 behavior was a bug, but people may have relied upon it. To get this 2044 behavior back, you can .include /etc/src.conf from /etc/make.conf 2045 (which is still global and isn't changed). This also changes the 2046 behavior of incremental builds inside the tree of individual 2047 directories. Set MAKESYSPATH to ".../share/mk" to do that. 2048 Although this has survived make universe and some upgrade scenarios, 2049 other upgrade scenarios may have broken. At least one form of 2050 temporary breakage was fixed with MAKESYSPATH settings for buildworld 2051 as well... In cases where MAKESYSPATH isn't working with this 2052 setting, you'll need to set it to the full path to your tree. 2053 2054 One side effect of all this cleaning up is that bsd.compiler.mk 2055 is no longer implicitly included by bsd.own.mk. If you wish to 2056 use COMPILER_TYPE, you must now explicitly include bsd.compiler.mk 2057 as well. 2058 205920140430: 2060 The lindev device has been removed since /dev/full has been made a 2061 standard device. __FreeBSD_version has been bumped. 2062 206320140424: 2064 The knob WITHOUT_VI was added to the base system, which controls 2065 building ex(1), vi(1), etc. Older releases of FreeBSD required ex(1) 2066 in order to reorder files share/termcap and didn't build ex(1) as a 2067 build tool, so building/installing with WITH_VI is highly advised for 2068 build hosts for older releases. 2069 2070 This issue has been fixed in stable/9 and stable/10 in r277022 and 2071 r276991, respectively. 2072 207320140418: 2074 The YES_HESIOD knob has been removed. It has been obsolete for 2075 a decade. Please move to using WITH_HESIOD instead or your builds 2076 will silently lack HESIOD. 2077 207820140405: 2079 The uart(4) driver has been changed with respect to its handling 2080 of the low-level console. Previously the uart(4) driver prevented 2081 any process from changing the baudrate or the CLOCAL and HUPCL 2082 control flags. By removing the restrictions, operators can make 2083 changes to the serial console port without having to reboot. 2084 However, when getty(8) is started on the serial device that is 2085 associated with the low-level console, a misconfigured terminal 2086 line in /etc/ttys will now have a real impact. 2087 Before upgrading the kernel, make sure that /etc/ttys has the 2088 serial console device configured as 3wire without baudrate to 2089 preserve the previous behaviour. E.g: 2090 ttyu0 "/usr/libexec/getty 3wire" vt100 on secure 2091 209220140306: 2093 Support for libwrap (TCP wrappers) in rpcbind was disabled by default 2094 to improve performance. To re-enable it, if needed, run rpcbind 2095 with command line option -W. 2096 209720140226: 2098 Switched back to the GPL dtc compiler due to updates in the upstream 2099 dts files not being supported by the BSDL dtc compiler. You will need 2100 to rebuild your kernel toolchain to pick up the new compiler. Core dumps 2101 may result while building dtb files during a kernel build if you fail 2102 to do so. Set WITHOUT_GPL_DTC if you require the BSDL compiler. 2103 210420140216: 2105 Clang and llvm have been upgraded to 3.4 release. 2106 210720140216: 2108 The nve(4) driver has been removed. Please use the nfe(4) driver 2109 for NVIDIA nForce MCP Ethernet adapters instead. 2110 211120140212: 2112 An ABI incompatibility crept into the libc++ 3.4 import in r261283. 2113 This could cause certain C++ applications using shared libraries built 2114 against the previous version of libc++ to crash. The incompatibility 2115 has now been fixed, but any C++ applications or shared libraries built 2116 between r261283 and r261801 should be recompiled. 2117 211820140204: 2119 OpenSSH will now ignore errors caused by kernel lacking of Capsicum 2120 capability mode support. Please note that enabling the feature in 2121 kernel is still highly recommended. 2122 212320140131: 2124 OpenSSH is now built with sandbox support, and will use sandbox as 2125 the default privilege separation method. This requires Capsicum 2126 capability mode support in kernel. 2127 212820140128: 2129 The libelf and libdwarf libraries have been updated to newer 2130 versions from upstream. Shared library version numbers for 2131 these two libraries were bumped. Any ports or binaries 2132 requiring these two libraries should be recompiled. 2133 __FreeBSD_version is bumped to 1100006. 2134 213520140110: 2136 If a Makefile in a tests/ directory was auto-generating a Kyuafile 2137 instead of providing an explicit one, this would prevent such 2138 Makefile from providing its own Kyuafile in the future during 2139 NO_CLEAN builds. This has been fixed in the Makefiles but manual 2140 intervention is needed to clean an objdir if you use NO_CLEAN: 2141 # find /usr/obj -name Kyuafile | xargs rm -f 2142 214320131213: 2144 The behavior of gss_pseudo_random() for the krb5 mechanism 2145 has changed, for applications requesting a longer random string 2146 than produced by the underlying enctype's pseudo-random() function. 2147 In particular, the random string produced from a session key of 2148 enctype aes256-cts-hmac-sha1-96 or aes256-cts-hmac-sha1-96 will 2149 be different at the 17th octet and later, after this change. 2150 The counter used in the PRF+ construction is now encoded as a 2151 big-endian integer in accordance with RFC 4402. 2152 __FreeBSD_version is bumped to 1100004. 2153 215420131108: 2155 The WITHOUT_ATF build knob has been removed and its functionality 2156 has been subsumed into the more generic WITHOUT_TESTS. If you were 2157 using the former to disable the build of the ATF libraries, you 2158 should change your settings to use the latter. 2159 216020131025: 2161 The default version of mtree is nmtree which is obtained from 2162 NetBSD. The output is generally the same, but may vary 2163 slightly. If you found you need identical output adding 2164 "-F freebsd9" to the command line should do the trick. For the 2165 time being, the old mtree is available as fmtree. 2166 216720131014: 2168 libbsdyml has been renamed to libyaml and moved to /usr/lib/private. 2169 This will break ports-mgmt/pkg. Rebuild the port, or upgrade to pkg 2170 1.1.4_8 and verify bsdyml not linked in, before running "make 2171 delete-old-libs": 2172 # make -C /usr/ports/ports-mgmt/pkg build deinstall install clean 2173 or 2174 # pkg install pkg; ldd /usr/local/sbin/pkg | grep bsdyml 2175 217620131010: 2177 The stable/10 branch has been created in subversion from head 2178 revision r256279. 2179 2180COMMON ITEMS: 2181 2182 General Notes 2183 ------------- 2184 Sometimes, obscure build problems are the result of environment 2185 poisoning. This can happen because the make utility reads its 2186 environment when searching for values for global variables. To run 2187 your build attempts in an "environmental clean room", prefix all make 2188 commands with 'env -i '. See the env(1) manual page for more details. 2189 Occasionally a build failure will occur with "make -j" due to a race 2190 condition. If this happens try building again without -j, and please 2191 report a bug if it happens consistently. 2192 2193 When upgrading from one major version to another it is generally best to 2194 upgrade to the latest code in the currently installed branch first, then 2195 do an upgrade to the new branch. This is the best-tested upgrade path, 2196 and has the highest probability of being successful. Please try this 2197 approach if you encounter problems with a major version upgrade. Since 2198 the stable 4.x branch point, one has generally been able to upgrade from 2199 anywhere in the most recent stable branch to head / current (or even the 2200 last couple of stable branches). See the top of this file when there's 2201 an exception. 2202 2203 The update process will emit an error on an attempt to perform a build 2204 or install from a FreeBSD version below the earliest supported version. 2205 When updating from an older version the update should be performed one 2206 major release at a time, including running `make delete-old` at each 2207 step. 2208 2209 When upgrading a live system, having a root shell around before 2210 installing anything can help undo problems. Not having a root shell 2211 around can lead to problems if pam has changed too much from your 2212 starting point to allow continued authentication after the upgrade. 2213 2214 This file should be read as a log of events. When a later event changes 2215 information of a prior event, the prior event should not be deleted. 2216 Instead, a pointer to the entry with the new information should be 2217 placed in the old entry. Readers of this file should also sanity check 2218 older entries before relying on them blindly. Authors of new entries 2219 should write them with this in mind. 2220 2221 ZFS notes 2222 --------- 2223 When upgrading the boot ZFS pool to a new version, always follow 2224 these two steps: 2225 2226 1.) recompile and reinstall the ZFS boot loader and boot block 2227 (this is part of "make buildworld" and "make installworld") 2228 2229 2.) update the ZFS boot block on your boot drive 2230 2231 The following example updates the ZFS boot block on the 2232 freebsd-boot partition of a GPT partitioned drive ada0: 2233 "gpart bootcode -p /boot/gptzfsboot -i $N ada0" 2234 The value $N will typically be 1 (if booting from BIOS) or 2 (if 2235 booting from EFI). 2236 2237 Non-boot pools do not need these updates. 2238 2239 To build a kernel 2240 ----------------- 2241 If you are updating from a prior version of FreeBSD (even one just 2242 a few days old), you should follow this procedure. It is the most 2243 failsafe as it uses a /usr/obj tree with a fresh mini-buildworld, 2244 2245 make kernel-toolchain 2246 make -DALWAYS_CHECK_MAKE buildkernel KERNCONF=YOUR_KERNEL_HERE 2247 make -DALWAYS_CHECK_MAKE installkernel KERNCONF=YOUR_KERNEL_HERE 2248 2249 To test a kernel once 2250 --------------------- 2251 If you just want to boot a kernel once (because you are not sure 2252 if it works, or if you want to boot a known bad kernel to provide 2253 debugging information) run 2254 make installkernel KERNCONF=YOUR_KERNEL_HERE KODIR=/boot/testkernel 2255 nextboot -k testkernel 2256 2257 To rebuild everything and install it on the current system. 2258 ----------------------------------------------------------- 2259 # Note: sometimes if you are running current you gotta do more than 2260 # is listed here if you are upgrading from a really old current. 2261 2262 <make sure you have good level 0 dumps> 2263 make buildworld 2264 make buildkernel KERNCONF=YOUR_KERNEL_HERE 2265 make installkernel KERNCONF=YOUR_KERNEL_HERE 2266 [1] 2267 <reboot in single user> [3] 2268 mergemaster -Fp [5] 2269 make installworld 2270 mergemaster -Fi [4] 2271 make delete-old [6] 2272 <reboot> 2273 2274 To cross-install current onto a separate partition 2275 -------------------------------------------------- 2276 # In this approach we use a separate partition to hold 2277 # current's root, 'usr', and 'var' directories. A partition 2278 # holding "/", "/usr" and "/var" should be about 2GB in 2279 # size. 2280 2281 <make sure you have good level 0 dumps> 2282 <boot into -stable> 2283 make buildworld 2284 make buildkernel KERNCONF=YOUR_KERNEL_HERE 2285 <maybe newfs current's root partition> 2286 <mount current's root partition on directory ${CURRENT_ROOT}> 2287 make installworld DESTDIR=${CURRENT_ROOT} -DDB_FROM_SRC 2288 make distribution DESTDIR=${CURRENT_ROOT} # if newfs'd 2289 make installkernel KERNCONF=YOUR_KERNEL_HERE DESTDIR=${CURRENT_ROOT} 2290 cp /etc/fstab ${CURRENT_ROOT}/etc/fstab # if newfs'd 2291 <edit ${CURRENT_ROOT}/etc/fstab to mount "/" from the correct partition> 2292 <reboot into current> 2293 <do a "native" rebuild/install as described in the previous section> 2294 <maybe install compatibility libraries from ports/misc/compat*> 2295 <reboot> 2296 2297 2298 To upgrade in-place from stable to current 2299 ---------------------------------------------- 2300 <make sure you have good level 0 dumps> 2301 make buildworld [9] 2302 make buildkernel KERNCONF=YOUR_KERNEL_HERE [8] 2303 make installkernel KERNCONF=YOUR_KERNEL_HERE 2304 [1] 2305 <reboot in single user> [3] 2306 mergemaster -Fp [5] 2307 make installworld 2308 mergemaster -Fi [4] 2309 make delete-old [6] 2310 <reboot> 2311 2312 Make sure that you've read the UPDATING file to understand the 2313 tweaks to various things you need. At this point in the life 2314 cycle of current, things change often and you are on your own 2315 to cope. The defaults can also change, so please read ALL of 2316 the UPDATING entries. 2317 2318 Also, if you are tracking -current, you must be subscribed to 2319 freebsd-current@freebsd.org. Make sure that before you update 2320 your sources that you have read and understood all the recent 2321 messages there. If in doubt, please track -stable which has 2322 much fewer pitfalls. 2323 2324 [1] If you have third party modules, such as vmware, you should disable 2325 them at this point so they don't crash your system on 2326 reboot. Alternatively, you should rebuild all the modules you have in 2327 your system and install them as well. If you are running -current, you 2328 should seriously consider placing all sources to all the modules for 2329 your system (or symlinks to them) in /usr/local/sys/modules so this 2330 happens automatically. If all your modules come from ports, then adding 2331 the port origin directories to PORTS_MODULES instead is also automatic 2332 and effective, eg: 2333 PORTS_MODULES+=x11/nvidia-driver 2334 2335 [3] From the bootblocks, boot -s, and then do 2336 fsck -p 2337 mount -u / 2338 mount -a 2339 sh /etc/rc.d/zfs start # mount zfs filesystem, if needed 2340 cd src # full path to source 2341 adjkerntz -i # if CMOS is wall time 2342 Also, when doing a major release upgrade, it is required that you boot 2343 into single user mode to do the installworld. 2344 2345 [4] Note: This step is non-optional. Failure to do this step 2346 can result in a significant reduction in the functionality of the 2347 system. Attempting to do it by hand is not recommended and those 2348 that pursue this avenue should read this file carefully, as well 2349 as the archives of freebsd-current and freebsd-hackers mailing lists 2350 for potential gotchas. The -U option is also useful to consider. 2351 See mergemaster(8) for more information. 2352 2353 [5] Usually this step is a no-op. However, from time to time 2354 you may need to do this if you get unknown user in the following 2355 step. It never hurts to do it all the time. You may need to 2356 install a new mergemaster (cd src/usr.sbin/mergemaster && make 2357 install) after the buildworld before this step if you last updated 2358 from current before 20130425 or from -stable before 20130430. 2359 2360 [6] This only deletes old files and directories. Old libraries 2361 can be deleted by "make delete-old-libs", but you have to make 2362 sure that no program is using those libraries anymore. 2363 2364 [8] The new kernel must be able to run existing binaries used by an 2365 installworld. When upgrading across major versions, the new kernel's 2366 configuration must include the correct COMPAT_FREEBSD<n> option for 2367 existing binaries (e.g. COMPAT_FREEBSD11 to run 11.x binaries). Failure 2368 to do so may leave you with a system that is hard to boot to recover. A 2369 GENERIC kernel will include suitable compatibility options to run 2370 binaries from older branches. Note that the ability to run binaries 2371 from unsupported branches is not guaranteed. 2372 2373 Make sure that you merge any new devices from GENERIC since the 2374 last time you updated your kernel config file. Options also 2375 change over time, so you may need to adjust your custom kernels 2376 for these as well. 2377 2378 [9] If CPUTYPE is defined in your /etc/make.conf, make sure to use the 2379 "?=" instead of the "=" assignment operator, so that buildworld can 2380 override the CPUTYPE if it needs to. 2381 2382 MAKEOBJDIRPREFIX must be defined in an environment variable, and 2383 not on the command line, or in /etc/make.conf. buildworld will 2384 warn if it is improperly defined. 2385FORMAT: 2386 2387This file contains a list, in reverse chronological order, of major 2388breakages in tracking -current. It is not guaranteed to be a complete 2389list of such breakages, and only contains entries since September 23, 2011. 2390If you need to see UPDATING entries from before that date, you will need 2391to fetch an UPDATING file from an older FreeBSD release. 2392 2393Copyright information: 2394 2395Copyright 1998-2009 M.
