1 Updating Information for FreeBSD current users. 2 3This file is maintained and copyrighted by M. Warner Losh <imp@freebsd.org>. 4See end of file for further details. For commonly done items, please see the 5COMMON ITEMS: section later in the file. These instructions assume that you 6basically know what you are doing. If not, then please consult the FreeBSD 7handbook: 8 9 https://www.freebsd.org/doc/en_US.ISO8859-1/books/handbook/makeworld.html 10 11Items affecting the ports and packages system can be found in 12/usr/ports/UPDATING. Please read that file before running portupgrade. 13 14NOTE TO PEOPLE WHO THINK THAT FreeBSD 13.x IS SLOW: 15 FreeBSD 13.x has many debugging features turned on, in both the kernel 16 and userland. These features attempt to detect incorrect use of 17 system primitives, and encourage loud failure through extra sanity 18 checking and fail stop semantics. They also substantially impact 19 system performance. If you want to do performance measurement, 20 benchmarking, and optimization, you'll want to turn them off. This 21 includes various WITNESS- related kernel options, INVARIANTS, malloc 22 debugging flags in userland, and various verbose features in the 23 kernel. Many developers choose to disable these features on build 24 machines to maximize performance. (To completely disable malloc 25 debugging, define MALLOC_PRODUCTION in /etc/make.conf, or to merely 26 disable the most expensive debugging functionality run 27 "ln -s 'abort:false,junk:false' /etc/malloc.conf".) 28 2920191226: 30 Clang/LLVM is now the default compiler for all powerpc architectures. 31 LLD is now the default linker for powerpc64. The change for powerpc64 32 also includes a change to the ELFv2 ABI, incompatible with the existing 33 ABI. 34 3520191226: 36 Kernel-loadable random(4) modules are no longer unloadable. 37 3820191222: 39 Clang, llvm, lld, lldb, compiler-rt, libc++, libunwind and openmp have 40 been upgraded to 9.0.1. Please see the 20141231 entry below for 41 information about prerequisites and upgrading, if you are not already 42 using clang 3.5.0 or higher. 43 4420191212: 45 r355677 has modified the internal interface used between the 46 NFS modules in the kernel. As such, they must all be upgraded 47 simultaneously. I will do a version bump for this. 48 4920191205: 50 The root certificates of the Mozilla CA Certificate Store have been 51 imported into the base system and can be managed with the certctl(8) 52 utility. If you have installed the security/ca_root_nss port or package 53 with the ETCSYMLINK option (the default), be advised that there may be 54 differences between those included in the port and those included in 55 base due to differences in nss branch used as well as general update 56 frequency. Note also that certctl(8) cannot manage certs in the 57 format used by the security/ca_root_nss port. 58 5920191120: 60 The amd(8) automount daemon has been disabled by default, and will be 61 removed in the future. As of FreeBSD 10.1 the autofs(5) is available 62 for automounting. 63 6420191107: 65 The nctgpio and wbwd drivers have been moved to the superio bus. 66 If you have one of these drivers in a kernel configuration, then 67 you should add device superio to it. If you use one of these drivers 68 as a module and you compile a custom set of modules, then you should 69 add superio to the set. 70 7120191021: 72 KPIs for network drivers to access interface addresses have changed. 73 Users need to recompile NIC driver modules together with kernel. 74 7520191021: 76 The net.link.tap.user_open sysctl no longer prevents user opening of 77 already created /dev/tapNN devices. Access is still controlled by 78 node permissions, just like tun devices. The net.link.tap.user_open 79 sysctl is now used only to allow users to perform devfs cloning of 80 tap devices, and the subsequent open may not succeed if the user is not 81 in the appropriate group. This sysctl may be deprecated/removed 82 completely in the future. 83 8420191009: 85 mips, powerpc, and sparc64 are no longer built as part of 86 universe / tinderbox unless MAKE_OBSOLETE_GCC is defined. If 87 not defined, mips, powerpc, and sparc64 builds will look for 88 the xtoolchain binaries and if installed use them for universe 89 builds. As llvm 9.0 becomes vetted for these architectures, they 90 will be removed from the list. 91 9220191009: 93 Clang, llvm, lld, lldb, compiler-rt, libc++, libunwind and openmp have 94 been upgraded to 9.0.0. Please see the 20141231 entry below for 95 information about prerequisites and upgrading, if you are not already 96 using clang 3.5.0 or higher. 97 9820191003: 99 The hpt27xx, hptmv, hptnr, and hptrr drivers have been removed from 100 GENERIC. They are available as modules and can be loaded by adding 101 to /boot/loader.conf hpt27xx_load="YES", hptmv_load="YES", 102 hptnr_load="YES", or hptrr_load="YES", respectively. 103 10420190913: 105 ntpd no longer by default locks its pages in memory, allowing them 106 to be paged out by the kernel. Use rlimit memlock to restore 107 historic BSD behaviour. For example, add "rlimit memlock 32" 108 to ntp.conf to lock up to 32 MB of ntpd address space in memory. 109 11020190823: 111 Several of ping6's options have been renamed for better consistency 112 with ping. If you use any of -ARWXaghmrtwx, you must update your 113 scripts. See ping6(8) for details. 114 11520190727: 116 The vfs.fusefs.sync_unmount and vfs.fusefs.init_backgrounded sysctls 117 and the "-o sync_unmount" and "-o init_backgrounded" mount options have 118 been removed from mount_fusefs(8). You can safely remove them from 119 your scripts, because they had no effect. 120 121 The vfs.fusefs.fix_broken_io, vfs.fusefs.sync_resize, 122 vfs.fusefs.refresh_size, vfs.fusefs.mmap_enable, 123 vfs.fusefs.reclaim_revoked, and vfs.fusefs.data_cache_invalidate 124 sysctls have been removed. If you felt the need to set any of them to 125 a non-default value, please tell asomers@FreeBSD.org why. 126 12720190713: 128 Default permissions on the /var/account/acct file (and copies of it 129 rotated by periodic daily scripts) are changed from 0644 to 0640 130 because the file contains sensitive information that should not be 131 world-readable. If the /var/account directory must be created by 132 rc.d/accounting, the mode used is now 0750. Admins who use the 133 accounting feature are encouraged to change the mode of an existing 134 /var/account directory to 0750 or 0700. 135 13620190620: 137 Entropy collection and the /dev/random device are no longer optional 138 components. The "device random" option has been removed. 139 Implementations of distilling algorithms can still be made loadable 140 with "options RANDOM_LOADABLE" (e.g., random_fortuna.ko). 141 14220190612: 143 Clang, llvm, lld, lldb, compiler-rt, libc++, libunwind and openmp have 144 been upgraded to 8.0.1. Please see the 20141231 entry below for 145 information about prerequisites and upgrading, if you are not already 146 using clang 3.5.0 or higher. 147 14820190608: 149 A fix was applied to i386 kernel modules to avoid panics with 150 dpcpu or vnet. Users need to recompile i386 kernel modules 151 having pcpu or vnet sections or they will refuse to load. 152 15320190513: 154 User-wired pages now have their own counter, 155 vm.stats.vm.v_user_wire_count. The vm.max_wired sysctl was renamed 156 to vm.max_user_wired and changed from an unsigned int to an unsigned 157 long. bhyve VMs wired with the -S are now subject to the user 158 wiring limit; the vm.max_user_wired sysctl may need to be tuned to 159 avoid running into the limit. 160 16120190507: 162 The IPSEC option has been removed from GENERIC. Users requiring 163 ipsec(4) must now load the ipsec(4) kernel module. 164 16520190507: 166 The tap(4) driver has been folded into tun(4), and the module has been 167 renamed to tuntap. You should update any kld_list="if_tap" or 168 kld_list="if_tun" entries in /etc/rc.conf, if_tap_load="YES" or 169 if_tun_load="YES" entries in /boot/loader.conf to load the if_tuntap 170 module instead, and "device tap" or "device tun" entries in kernel 171 config files to select the tuntap device instead. 172 17320190418: 174 The following knobs have been added related to tradeoffs between 175 safe use of the random device and availability in the absence of 176 entropy: 177 178 kern.random.initial_seeding.bypass_before_seeding: tunable; set 179 non-zero to bypass the random device prior to seeding, or zero to 180 block random requests until the random device is initially seeded. 181 For now, set to 1 (unsafe) by default to restore pre-r346250 boot 182 availability properties. 183 184 kern.random.initial_seeding.read_random_bypassed_before_seeding: 185 read-only diagnostic sysctl that is set when bypass is enabled and 186 read_random(9) is bypassed, to enable programmatic handling of this 187 initial condition, if desired. 188 189 kern.random.initial_seeding.arc4random_bypassed_before_seeding: 190 Similar to the above, but for for arc4random(9) initial seeding. 191 192 kern.random.initial_seeding.disable_bypass_warnings: tunable; set 193 non-zero to disable warnings in dmesg when the same conditions are 194 met as for the diagnostic sysctls above. Defaults to zero, i.e., 195 produce warnings in dmesg when the conditions are met. 196 19720190416: 198 The loadable random module KPI has changed; the random_infra_init() 199 routine now requires a 3rd function pointer for a bool (*)(void) 200 method that returns true if the random device is seeded (and 201 therefore unblocked). 202 20320190404: 204 r345895 reverts r320698. This implies that an nfsuserd(8) daemon 205 built from head sources between r320757 (July 6, 2017) and 206 r338192 (Aug. 22, 2018) will not work unless the "-use-udpsock" 207 is added to the command line. 208 nfsuserd daemons built from head sources that are post-r338192 are 209 not affected and should continue to work. 210 21120190320: 212 The fuse(4) module has been renamed to fusefs(4) for consistency with 213 other filesystems. You should update any kld_load="fuse" entries in 214 /etc/rc.conf, fuse_load="YES" entries in /boot/loader.conf, and 215 "options FUSE" entries in kernel config files. 216 21720190304: 218 Clang, llvm, lld, lldb, compiler-rt and libc++ have been upgraded to 219 8.0.0. Please see the 20141231 entry below for information about 220 prerequisites and upgrading, if you are not already using clang 3.5.0 221 or higher. 222 22320190226: 224 geom_uzip(4) depends on the new module xz. If geom_uzip is statically 225 compiled into your custom kernel, add 'device xz' statement to the 226 kernel config. 227 22820190219: 229 drm and drm2 have been removed from the tree. Please see 230 https://wiki.freebsd.org/Graphics for the latest information on 231 migrating to the drm ports. 232 23320190131: 234 Iflib is no longer unconditionally compiled into the kernel. Drivers 235 using iflib and statically compiled into the kernel, now require 236 the 'device iflib' config option. For the same drivers loaded as 237 modules on kernels not having 'device iflib', the iflib.ko module 238 is loaded automatically. 239 24020190125: 241 The IEEE80211_AMPDU_AGE and AH_SUPPORT_AR5416 kernel configuration 242 options no longer exist since r343219 and r343427 respectively; 243 nothing uses them, so they should be just removed from custom 244 kernel config files. 245 24620181230: 247 r342635 changes the way efibootmgr(8) works by requiring users to add 248 the -b (bootnum) parameter for commands where the bootnum was previously 249 specified with each option. For example 'efibootmgr -B 0001' is now 250 'efibootmgr -B -b 0001'. 251 25220181220: 253 r342286 modifies the NFSv4 server so that it obeys vfs.nfsd.nfs_privport 254 in the same as it is applied to NFSv2 and 3. This implies that NFSv4 255 servers that have vfs.nfsd.nfs_privport set will only allow mounts 256 from clients using a reserved port#. Since both the FreeBSD and Linux 257 NFSv4 clients use reserved port#s by default, this should not affect 258 most NFSv4 mounts. 259 26020181219: 261 The XLP config has been removed. We can't support 64-bit atomics in this 262 kernel because it is running in 32-bit mode. XLP users must transition 263 to running a 64-bit kernel (XLP64 or XLPN32). 264 265 The mips GXEMUL support has been removed from FreeBSD. MALTA* + qemu is 266 the preferred emulator today and we don't need two different ones. 267 268 The old sibyte / swarm / Broadcom BCM1250 support has been 269 removed from the mips port. 270 27120181211: 272 Clang, llvm, lld, lldb, compiler-rt and libc++ have been upgraded to 273 7.0.1. Please see the 20141231 entry below for information about 274 prerequisites and upgrading, if you are not already using clang 3.5.0 275 or higher. 276 27720181211: 278 Remove the timed and netdate programs from the base tree. Setting 279 the time with these daemons has been obsolete for over a decade. 280 28120181126: 282 On amd64, arm64 and armv7 (architectures that install LLVM's ld.lld 283 linker as /usr/bin/ld) GNU ld is no longer installed as ld.bfd, as 284 it produces broken binaries when ifuncs are in use. Users needing 285 GNU ld should install the binutils port or package. 286 28720181123: 288 The BSD crtbegin and crtend code has been enabled by default. It has 289 had extensive testing on amd64, arm64, and i386. It can be disabled 290 by building a world with -DWITHOUT_BSD_CRTBEGIN. 291 29220181115: 293 The set of CTM commands (ctm, ctm_smail, ctm_rmail, ctm_dequeue) 294 has been converted to a port (misc/ctm) and will be removed from 295 FreeBSD-13. It is available as a package (ctm) for all supported 296 FreeBSD versions. 297 29820181110: 299 The default newsyslog.conf(5) file has been changed to only include 300 files in /etc/newsyslog.conf.d/ and /usr/local/etc/newsyslog.conf.d/ if 301 the filenames end in '.conf' and do not begin with a '.'. 302 303 You should check the configuration files in these two directories match 304 this naming convention. You can verify which configuration files are 305 being included using the command: 306 $ newsyslog -Nrv 307 30820181015: 309 Ports for the DRM modules have been simplified. Now, amd64 users should 310 just install the drm-kmod port. All others should install 311 drm-legacy-kmod. 312 313 Graphics hardware that's newer than about 2010 usually works with 314 drm-kmod. For hardware older than 2013, however, some users will need 315 to use drm-legacy-kmod if drm-kmod doesn't work for them. Hardware older 316 than 2008 usually only works in drm-legacy-kmod. The graphics team can 317 only commit to hardware made since 2013 due to the complexity of the 318 market and difficulty to test all the older cards effectively. If you 319 have hardware supported by drm-kmod, you are strongly encouraged to use 320 that as you will get better support. 321 322 Other than KPI chasing, drm-legacy-kmod will not be updated. As outlined 323 elsewhere, the drm and drm2 modules will be eliminated from the src base 324 soon (with a limited exception for arm). Please update to the package 325 asap and report any issues to x11@freebsd.org. 326 327 Generally, anybody using the drm*-kmod packages should add 328 WITHOUT_DRM_MODULE=t and WITHOUT_DRM2_MODULE=t to avoid nasty 329 cross-threading surprises, especially with automatic driver 330 loading from X11 startup. These will become the defaults in 13-current 331 shortly. 332 33320181012: 334 The ixlv(4) driver has been renamed to iavf(4). As a consequence, 335 custom kernel and module loading configuration files must be updated 336 accordingly. Moreover, interfaces previous presented as ixlvN to the 337 system are now exposed as iavfN and network configuration files must 338 be adjusted as necessary. 339 34020181009: 341 OpenSSL has been updated to version 1.1.1. This update included 342 additional various API changes throughout the base system. It is 343 important to rebuild third-party software after upgrading. The value 344 of __FreeBSD_version has been bumped accordingly. 345 34620181006: 347 The legacy DRM modules and drivers have now been added to the loader's 348 module blacklist, in favor of loading them with kld_list in rc.conf(5). 349 The module blacklist may be overridden with the loader.conf(5) 350 'module_blacklist' variable, but loading them via rc.conf(5) is strongly 351 encouraged. 352 35320181002: 354 The cam(4) based nda(4) driver will be used over nvd(4) by default on 355 powerpc64. You may set 'options NVME_USE_NVD=1' in your kernel conf or 356 loader tunable 'hw.nvme.use_nvd=1' if you wish to use the existing 357 driver. Make sure to edit /boot/etc/kboot.conf and fstab to use the 358 nda device name. 359 36020180913: 361 Reproducible build mode is now on by default, in preparation for 362 FreeBSD 12.0. This eliminates build metadata such as the user, 363 host, and time from the kernel (and uname), unless the working tree 364 corresponds to a modified checkout from a version control system. 365 The previous behavior can be obtained by setting the /etc/src.conf 366 knob WITHOUT_REPRODUCIBLE_BUILD. 367 36820180826: 369 The Yarrow CSPRNG has been removed from the kernel as it has not been 370 supported by its designers since at least 2003. Fortuna has been the 371 default since FreeBSD-11. 372 37320180822: 374 devctl freeze/thaw have gone into the tree, the rc scripts have been 375 updated to use them and devmatch has been changed. You should update 376 kernel, userland and rc scripts all at the same time. 377 37820180818: 379 The default interpreter has been switched from 4th to Lua. 380 LOADER_DEFAULT_INTERP, documented in build(7), will override the default 381 interpreter. If you have custom FORTH code you will need to set 382 LOADER_DEFAULT_INTERP=4th (valid values are 4th, lua or simp) in 383 src.conf for the build. This will create default hard links between 384 loader and loader_4th instead of loader and loader_lua, the new default. 385 If you are using UEFI it will create the proper hard link to loader.efi. 386 387 bhyve uses userboot.so. It remains 4th-only until some issues are solved 388 regarding coexisting with multiple versions of FreeBSD are resolved. 389 39020180815: 391 ls(1) now respects the COLORTERM environment variable used in other 392 systems and software to indicate that a colored terminal is both 393 supported and desired. If ls(1) is suddenly emitting colors, they may 394 be disabled again by either removing the unwanted COLORTERM from your 395 environment, or using `ls --color=never`. The ls(1) specific CLICOLOR 396 may not be observed in a future release. 397 39820180808: 399 The default pager for most commands has been changed to "less". To 400 restore the old behavior, set PAGER="more" and MANPAGER="more -s" in 401 your environment. 402 40320180731: 404 The jedec_ts(4) driver has been removed. A superset of its functionality 405 is available in the jedec_dimm(4) driver, and the manpage for that 406 driver includes migration instructions. If you have "device jedec_ts" 407 in your kernel configuration file, it must be removed. 408 40920180730: 410 amd64/GENERIC now has EFI runtime services, EFIRT, enabled by default. 411 This should have no effect if the kernel is booted via BIOS/legacy boot. 412 EFIRT may be disabled via a loader tunable, efi.rt.disabled, if a system 413 has a buggy firmware that prevents a successful boot due to use of 414 runtime services. 415 41620180727: 417 Atmel AT91RM9200 and AT91SAM9, Cavium CNS 11xx and XScale 418 support has been removed from the tree. These ports were 419 obsolete and/or known to be broken for many years. 420 42120180723: 422 loader.efi has been augmented to participate more fully in the 423 UEFI boot manager protocol. loader.efi will now look at the 424 BootXXXX environment variable to determine if a specific kernel 425 or root partition was specified. XXXX is derived from BootCurrent. 426 efibootmgr(8) manages these standard UEFI variables. 427 42820180720: 429 zfsloader's functionality has now been folded into loader. 430 zfsloader is no longer necessary once you've updated your 431 boot blocks. For a transition period, we will install a 432 hardlink for zfsloader to loader to allow a smooth transition 433 until the boot blocks can be updated (hard link because old 434 zfs boot blocks don't understand symlinks). 435 43620180719: 437 ARM64 now have efifb support, if you want to have serial console 438 on your arm64 board when an screen is connected and the bootloader 439 setup a frame buffer for us to use, just add : 440 boot_serial=YES 441 boot_multicons=YES 442 in /boot/loader.conf 443 For Raspberry Pi 3 (RPI) users, this is needed even if you don't have 444 an screen connected as the firmware will setup a frame buffer are that 445 u-boot will expose as an EFI frame buffer. 446 44720180719: 448 New uid:gid added, ntpd:ntpd (123:123). Be sure to run mergemaster 449 or take steps to update /etc/passwd before doing installworld on 450 existing systems. Do not skip the "mergemaster -Fp" step before 451 installworld, as described in the update procedures near the bottom 452 of this document. Also, rc.d/ntpd now starts ntpd(8) as user ntpd 453 if the new mac_ntpd(4) policy is available, unless ntpd_flags or 454 the ntp config file contain options that change file/dir locations. 455 When such options (e.g., "statsdir" or "crypto") are used, ntpd can 456 still be run as non-root by setting ntpd_user=ntpd in rc.conf, after 457 taking steps to ensure that all required files/dirs are accessible 458 by the ntpd user. 459 46020180717: 461 Big endian arm support has been removed. 462 46320180711: 464 The static environment setup in kernel configs is no longer mutually 465 exclusive with the loader(8) environment by default. In order to 466 restore the previous default behavior of disabling the loader(8) 467 environment if a static environment is present, you must specify 468 loader_env.disabled=1 in the static environment. 469 47020180705: 471 The ABI of syscalls used by management tools like sockstat and 472 netstat has been broken to allow 32-bit binaries to work on 473 64-bit kernels without modification. These programs will need 474 to match the kernel in order to function. External programs may 475 require minor modifications to accommodate a change of type in 476 structures from pointers to 64-bit virtual addresses. 477 47820180702: 479 On i386 and amd64 atomics are now inlined. Out of tree modules using 480 atomics will need to be rebuilt. 481 48220180701: 483 The '%I' format in the kern.corefile sysctl limits the number of 484 core files that a process can generate to the number stored in the 485 debug.ncores sysctl. The '%I' format is replaced by the single digit 486 index. Previously, if all indexes were taken the kernel would overwrite 487 only a core file with the highest index in a filename. 488 Currently the system will create a new core file if there is a free 489 index or if all slots are taken it will overwrite the oldest one. 490 49120180630: 492 Clang, llvm, lld, lldb, compiler-rt and libc++ have been upgraded to 493 6.0.1. Please see the 20141231 entry below for information about 494 prerequisites and upgrading, if you are not already using clang 3.5.0 495 or higher. 496 49720180628: 498 r335753 introduced a new quoting method. However, etc/devd/devmatch.conf 499 needed to be changed to work with it. This change was made with r335763 500 and requires a mergemaster / etcupdate / etc to update the installed 501 file. 502 50320180612: 504 r334930 changed the interface between the NFS modules, so they all 505 need to be rebuilt. r335018 did a __FreeBSD_version bump for this. 506 50720180530: 508 As of r334391 lld is the default amd64 system linker; it is installed 509 as /usr/bin/ld. Kernel build workarounds (see 20180510 entry) are no 510 longer necessary. 511 51220180530: 513 The kernel / userland interface for devinfo changed, so you'll 514 need a new kernel and userland as a pair for it to work (rebuilding 515 lib/libdevinfo is all that's required). devinfo and devmatch will 516 not work, but everything else will when there's a mismatch. 517 51820180523: 519 The on-disk format for hwpmc callchain records has changed to include 520 threadid corresponding to a given record. This changes the field offsets 521 and thus requires that libpmcstat be rebuilt before using a kernel 522 later than r334108. 523 52420180517: 525 The vxge(4) driver has been removed. This driver was introduced into 526 HEAD one week before the Exar left the Ethernet market and is not 527 known to be used. If you have device vxge in your kernel config file 528 it must be removed. 529 53020180510: 531 The amd64 kernel now requires a ld that supports ifunc to produce a 532 working kernel, either lld or a newer binutils. lld is built by default 533 on amd64, and the 'buildkernel' target uses it automatically. However, 534 it is not the default linker, so building the kernel the traditional 535 way requires LD=ld.lld on the command line (or LD=/usr/local/bin/ld for 536 binutils port/package). lld will soon be default, and this requirement 537 will go away. 538 539 NOTE: As of r334391 lld is the default system linker on amd64, and no 540 workaround is necessary. 541 54220180508: 543 The nxge(4) driver has been removed. This driver was for PCI-X 10g 544 cards made by s2io/Neterion. The company was acquired by Exar and 545 no longer sells or supports Ethernet products. If you have device 546 nxge in your kernel config file it must be removed. 547 54820180504: 549 The tz database (tzdb) has been updated to 2018e. This version more 550 correctly models time stamps in time zones with negative DST such as 551 Europe/Dublin (from 1971 on), Europe/Prague (1946/7), and 552 Africa/Windhoek (1994/2017). This does not affect the UT offsets, only 553 time zone abbreviations and the tm_isdst flag. 554 55520180502: 556 The ixgb(4) driver has been removed. This driver was for an early and 557 uncommon legacy PCI 10GbE for a single ASIC, Intel 82597EX. Intel 558 quickly shifted to the long lived ixgbe family. If you have device 559 ixgb in your kernel config file it must be removed. 560 56120180501: 562 The lmc(4) driver has been removed. This was a WAN interface 563 card that was already reportedly rare in 2003, and had an ambiguous 564 license. If you have device lmc in your kernel config file it must 565 be removed. 566 56720180413: 568 Support for Arcnet networks has been removed. If you have device 569 arcnet or device cm in your kernel config file they must be 570 removed. 571 57220180411: 573 Support for FDDI networks has been removed. If you have device 574 fddi or device fpa in your kernel config file they must be 575 removed. 576 57720180406: 578 In addition to supporting RFC 3164 formatted messages, the 579 syslogd(8) service is now capable of parsing RFC 5424 formatted 580 log messages. The main benefit of using RFC 5424 is that clients 581 may now send log messages with timestamps containing year numbers, 582 microseconds and time zone offsets. 583 584 Similarly, the syslog(3) C library function has been altered to 585 send RFC 5424 formatted messages to the local system logging 586 daemon. On systems using syslogd(8), this change should have no 587 negative impact, as long as syslogd(8) and the C library are 588 updated at the same time. On systems using a different system 589 logging daemon, it may be necessary to make configuration 590 adjustments, depending on the software used. 591 592 When using syslog-ng, add the 'syslog-protocol' flag to local 593 input sources to enable parsing of RFC 5424 formatted messages: 594 595 source src { 596 unix-dgram("/var/run/log" flags(syslog-protocol)); 597 } 598 599 When using rsyslog, disable the 'SysSock.UseSpecialParser' option 600 of the 'imuxsock' module to let messages be processed by the 601 regular RFC 3164/5424 parsing pipeline: 602 603 module(load="imuxsock" SysSock.UseSpecialParser="off") 604 605 Do note that these changes only affect communication between local 606 applications and syslogd(8). The format that syslogd(8) uses to 607 store messages on disk or forward messages to other systems 608 remains unchanged. syslogd(8) still uses RFC 3164 for these 609 purposes. Options to customize this behaviour will be added in the 610 future. Utilities that process log files stored in /var/log are 611 thus expected to continue to function as before. 612 613 __FreeBSD_version has been incremented to 1200061 to denote this 614 change. 615 61620180328: 617 Support for token ring networks has been removed. If you 618 have "device token" in your kernel config you should remove 619 it. No device drivers supported token ring. 620 62120180323: 622 makefs was modified to be able to tag ISO9660 El Torito boot catalog 623 entries as EFI instead of overloading the i386 tag as done previously. 624 The amd64 mkisoimages.sh script used to build amd64 ISO images for 625 release was updated to use this. This may mean that makefs must be 626 updated before "make cdrom" can be run in the release directory. This 627 should be as simple as: 628 629 $ cd $SRCDIR/usr.sbin/makefs 630 $ make depend all install 631 63220180212: 633 FreeBSD boot loader enhanced with Lua scripting. It's purely opt-in for 634 now by building WITH_LOADER_LUA and WITHOUT_FORTH in /etc/src.conf. 635 Co-existence for the transition period will come shortly. Booting is a 636 complex environment and test coverage for Lua-enabled loaders has been 637 thin, so it would be prudent to assume it might not work and make 638 provisions for backup boot methods. 639 64020180211: 641 devmatch functionality has been turned on in devd. It will automatically 642 load drivers for unattached devices. This may cause unexpected drivers 643 to be loaded. Please report any problems to current@ and 644 imp@freebsd.org. 645 64620180114: 647 Clang, llvm, lld, lldb, compiler-rt and libc++ have been upgraded to 648 6.0.0. Please see the 20141231 entry below for information about 649 prerequisites and upgrading, if you are not already using clang 3.5.0 650 or higher. 651 65220180110: 653 LLVM's lld linker is now used as the FreeBSD/amd64 bootstrap linker. 654 This means it is used to link the kernel and userland libraries and 655 executables, but is not yet installed as /usr/bin/ld by default. 656 657 To revert to ld.bfd as the bootstrap linker, in /etc/src.conf set 658 WITHOUT_LLD_BOOTSTRAP=yes 659 66020180110: 661 On i386, pmtimer has been removed. Its functionality has been folded 662 into apm. It was a no-op on ACPI in current for a while now (but was 663 still needed on i386 in FreeBSD 11 and earlier). Users may need to 664 remove it from kernel config files. 665 66620180104: 667 The use of RSS hash from the network card aka flowid has been 668 disabled by default for lagg(4) as it's currently incompatible with 669 the lacp and loadbalance protocols. 670 671 This can be re-enabled by setting the following in loader.conf: 672 net.link.lagg.default_use_flowid="1" 673 67420180102: 675 The SW_WATCHDOG option is no longer necessary to enable the 676 hardclock-based software watchdog if no hardware watchdog is 677 configured. As before, SW_WATCHDOG will cause the software 678 watchdog to be enabled even if a hardware watchdog is configured. 679 68020171215: 681 r326887 fixes the issue described in the 20171214 UPDATING entry. 682 r326888 flips the switch back to building GELI support always. 683 68420171214: 685 r362593 broke ZFS + GELI support for reasons unknown. However, 686 it also broke ZFS support generally, so GELI has been turned off 687 by default as the lesser evil in r326857. If you boot off ZFS and/or 688 GELI, it might not be a good time to update. 689 69020171125: 691 PowerPC users must update loader(8) by rebuilding world before 692 installing a new kernel, as the protocol connecting them has 693 changed. Without the update, loader metadata will not be passed 694 successfully to the kernel and users will have to enter their 695 root partition at the kernel mountroot prompt to continue booting. 696 Newer versions of loader can boot old kernels without issue. 697 69820171110: 699 The LOADER_FIREWIRE_SUPPORT build variable as been renamed to 700 WITH/OUT_LOADER_FIREWIRE. LOADER_{NO_,}GELI_SUPPORT has been renamed 701 to WITH/OUT_LOADER_GELI. 702 70320171106: 704 The naive and non-compliant support of posix_fallocate(2) in ZFS 705 has been removed as of r325320. The system call now returns EINVAL 706 when used on a ZFS file. Although the new behavior complies with the 707 standard, some consumers are not prepared to cope with it. 708 One known victim is lld prior to r325420. 709 71020171102: 711 Building in a FreeBSD src checkout will automatically create object 712 directories now rather than store files in the current directory if 713 'make obj' was not ran. Calling 'make obj' is no longer necessary. 714 This feature can be disabled by setting WITHOUT_AUTO_OBJ=yes in 715 /etc/src-env.conf (not /etc/src.conf), or passing the option in the 716 environment. 717 71820171101: 719 The default MAKEOBJDIR has changed from /usr/obj/<srcdir> for native 720 builds, and /usr/obj/<arch>/<srcdir> for cross-builds, to a unified 721 /usr/obj/<srcdir>/<arch>. This behavior can be changed to the old 722 format by setting WITHOUT_UNIFIED_OBJDIR=yes in /etc/src-env.conf, 723 the environment, or with -DWITHOUT_UNIFIED_OBJDIR when building. 724 The UNIFIED_OBJDIR option is a transitional feature that will be 725 removed for 12.0 release; please migrate to the new format for any 726 tools by looking up the OBJDIR used by 'make -V .OBJDIR' means rather 727 than hardcoding paths. 728 72920171028: 730 The native-xtools target no longer installs the files by default to the 731 OBJDIR. Use the native-xtools-install target with a DESTDIR to install 732 to ${DESTDIR}/${NXTP} where NXTP defaults to /nxb-bin. 733 73420171021: 735 As part of the boot loader infrastructure cleanup, LOADER_*_SUPPORT 736 options are changing from controlling the build if defined / undefined 737 to controlling the build with explicit 'yes' or 'no' values. They will 738 shift to WITH/WITHOUT options to match other options in the system. 739 74020171010: 741 libstand has turned into a private library for sys/boot use only. 742 It is no longer supported as a public interface outside of sys/boot. 743 74420171005: 745 The arm port has split armv6 into armv6 and armv7. armv7 is now 746 a valid TARGET_ARCH/MACHINE_ARCH setting. If you have an armv7 system 747 and are running a kernel from before r324363, you will need to add 748 MACHINE_ARCH=armv7 to 'make buildworld' to do a native build. 749 75020171003: 751 When building multiple kernels using KERNCONF, non-existent KERNCONF 752 files will produce an error and buildkernel will fail. Previously 753 missing KERNCONF files silently failed giving no indication as to 754 why, only to subsequently discover during installkernel that the 755 desired kernel was never built in the first place. 756 75720170912: 758 The default serial number format for CTL LUNs has changed. This will 759 affect users who use /dev/diskid/* device nodes, or whose FibreChannel 760 or iSCSI clients care about their LUNs' serial numbers. Users who 761 require serial number stability should hardcode serial numbers in 762 /etc/ctl.conf . 763 76420170912: 765 For 32-bit arm compiled for hard-float support, soft-floating point 766 binaries now always get their shared libraries from 767 LD_SOFT_LIBRARY_PATH (in the past, this was only used if 768 /usr/libsoft also existed). Only users with a hard-float ld.so, but 769 soft-float everything else should be affected. 770 77120170826: 772 The geli password typed at boot is now hidden. To restore the previous 773 behavior, see geli(8) for configuration options. 774 77520170825: 776 Move PMTUD blackhole counters to TCPSTATS and remove them from bare 777 sysctl values. Minor nit, but requires a rebuild of both world/kernel 778 to complete. 779 78020170814: 781 "make check" behavior (made in ^/head@r295380) has been changed to 782 execute from a limited sandbox, as opposed to executing from 783 ${TESTSDIR}. 784 785 Behavioral changes: 786 - The "beforecheck" and "aftercheck" targets are now specified. 787 - ${CHECKDIR} (added in commit noted above) has been removed. 788 - Legacy behavior can be enabled by setting 789 WITHOUT_MAKE_CHECK_USE_SANDBOX in src.conf(5) or the environment. 790 791 If the limited sandbox mode is enabled, "make check" will execute 792 "make distribution", then install, execute the tests, and clean up the 793 sandbox if successful. 794 795 The "make distribution" and "make install" targets are typically run as 796 root to set appropriate permissions and ownership at installation time. 797 The end-user should set "WITH_INSTALL_AS_USER" in src.conf(5) or the 798 environment if executing "make check" with limited sandbox mode using 799 an unprivileged user. 800 80120170808: 802 Since the switch to GPT disk labels, fsck for UFS/FFS has been 803 unable to automatically find alternate superblocks. As of r322297, 804 the information needed to find alternate superblocks has been 805 moved to the end of the area reserved for the boot block. 806 Filesystems created with a newfs of this vintage or later 807 will create the recovery information. If you have a filesystem 808 created prior to this change and wish to have a recovery block 809 created for your filesystem, you can do so by running fsck in 810 foreground mode (i.e., do not use the -p or -y options). As it 811 starts, fsck will ask ``SAVE DATA TO FIND ALTERNATE SUPERBLOCKS'' 812 to which you should answer yes. 813 81420170728: 815 As of r321665, an NFSv4 server configuration that services 816 Kerberos mounts or clients that do not support the uid/gid in 817 owner/owner_group string capability, must explicitly enable 818 the nfsuserd daemon by adding nfsuserd_enable="YES" to the 819 machine's /etc/rc.conf file. 820 82120170722: 822 Clang, llvm, lldb, compiler-rt and libc++ have been upgraded to 5.0.0. 823 Please see the 20141231 entry below for information about prerequisites 824 and upgrading, if you are not already using clang 3.5.0 or higher. 825 82620170701: 827 WITHOUT_RCMDS is now the default. Set WITH_RCMDS if you need the 828 r-commands (rlogin, rsh, etc.) to be built with the base system. 829 83020170625: 831 The FreeBSD/powerpc platform now uses a 64-bit type for time_t. This is 832 a very major ABI incompatible change, so users of FreeBSD/powerpc must 833 be careful when performing source upgrades. It is best to run 834 'make installworld' from an alternate root system, either a live 835 CD/memory stick, or a temporary root partition. Additionally, all ports 836 must be recompiled. powerpc64 is largely unaffected, except in the case 837 of 32-bit compatibility. All 32-bit binaries will be affected. 838 83920170623: 840 Forward compatibility for the "ino64" project have been committed. This 841 will allow most new binaries to run on older kernels in a limited 842 fashion. This prevents many of the common foot-shooting actions in the 843 upgrade as well as the limited ability to roll back the kernel across 844 the ino64 upgrade. Complicated use cases may not work properly, though 845 enough simpler ones work to allow recovery in most situations. 846 84720170620: 848 Switch back to the BSDL dtc (Device Tree Compiler). Set WITH_GPL_DTC 849 if you require the GPL compiler. 850 85120170618: 852 The internal ABI used for communication between the NFS kernel modules 853 was changed by r320085, so __FreeBSD_version was bumped to 854 ensure all the NFS related modules are updated together. 855 85620170617: 857 The ABI of struct event was changed by extending the data 858 member to 64bit and adding ext fields. For upgrade, same 859 precautions as for the entry 20170523 "ino64" must be 860 followed. 861 86220170531: 863 The GNU roff toolchain has been removed from base. To render manpages 864 which are not supported by mandoc(1), man(1) can fallback on GNU roff 865 from ports (and recommends to install it). 866 To render roff(7) documents, consider using GNU roff from ports or the 867 heirloom doctools roff toolchain from ports via pkg install groff or 868 via pkg install heirloom-doctools. 869 87020170524: 871 The ath(4) and ath_hal(4) modules now build piecemeal to allow for 872 smaller runtime footprint builds. This is useful for embedded systems 873 which only require one chipset support. 874 875 If you load it as a module, make sure this is in /boot/loader.conf: 876 877 if_ath_load="YES" 878 879 This will load the HAL, all chip/RF backends and if_ath_pci. 880 If you have if_ath_pci in /boot/loader.conf, ensure it is after 881 if_ath or it will not load any HAL chipset support. 882 883 If you want to selectively load things (eg on ye cheape ARM/MIPS 884 platforms where RAM is at a premium) you should: 885 886 * load ath_hal 887 * load the chip modules in question 888 * load ath_rate, ath_dfs 889 * load ath_main 890 * load if_ath_pci and/or if_ath_ahb depending upon your particular 891 bus bind type - this is where probe/attach is done. 892 893 For further comments/feedback, poke adrian@ . 894 89520170523: 896 The "ino64" 64-bit inode project has been committed, which extends 897 a number of types to 64 bits. Upgrading in place requires care and 898 adherence to the documented upgrade procedure. 899 900 If using a custom kernel configuration ensure that the 901 COMPAT_FREEBSD11 option is included (as during the upgrade the 902 system will be running the ino64 kernel with the existing world). 903 904 For the safest in-place upgrade begin by removing previous build 905 artifacts via "rm -rf /usr/obj/*". Then, carefully follow the full 906 procedure documented below under the heading "To rebuild everything and 907 install it on the current system." Specifically, a reboot is required 908 after installing the new kernel before installing world. While an 909 installworld normally works by accident from multiuser after rebooting 910 the proper kernel, there are many cases where this will fail across this 911 upgrade and installworld from single user is required. 912 91320170424: 914 The NATM framework including the en(4), fatm(4), hatm(4), and 915 patm(4) devices has been removed. Consumers should plan a 916 migration before the end-of-life date for FreeBSD 11. 917 91820170420: 919 GNU diff has been replaced by a BSD licensed diff. Some features of GNU 920 diff has not been implemented, if those are needed a newer version of 921 GNU diff is available via the diffutils package under the gdiff name. 922 92320170413: 924 As of r316810 for ipfilter, keep frags is no longer assumed when 925 keep state is specified in a rule. r316810 aligns ipfilter with 926 documentation in man pages separating keep frags from keep state. 927 This allows keep state to be specified without forcing keep frags 928 and allows keep frags to be specified independently of keep state. 929 To maintain previous behaviour, also specify keep frags with 930 keep state (as documented in ipf.conf.5). 931 93220170407: 933 arm64 builds now use the base system LLD 4.0.0 linker by default, 934 instead of requiring that the aarch64-binutils port or package be 935 installed. To continue using aarch64-binutils, set 936 CROSS_BINUTILS_PREFIX=/usr/local/aarch64-freebsd/bin . 937 93820170405: 939 The UDP optimization in entry 20160818 that added the sysctl 940 net.inet.udp.require_l2_bcast has been reverted. L2 broadcast 941 packets will no longer be treated as L3 broadcast packets. 942 94320170331: 944 Binds and sends to the loopback addresses, IPv6 and IPv4, will now 945 use any explicitly assigned loopback address available in the jail 946 instead of using the first assigned address of the jail. 947 94820170329: 949 The ctl.ko module no longer implements the iSCSI target frontend: 950 cfiscsi.ko does instead. 951 952 If building cfiscsi.ko as a kernel module, the module can be loaded 953 via one of the following methods: 954 - `cfiscsi_load="YES"` in loader.conf(5). 955 - Add `cfiscsi` to `$kld_list` in rc.conf(5). 956 - ctladm(8)/ctld(8), when compiled with iSCSI support 957 (`WITH_ISCSI=yes` in src.conf(5)) 958 959 Please see cfiscsi(4) for more details. 960 96120170316: 962 The mmcsd.ko module now additionally depends on geom_flashmap.ko. 963 Also, mmc.ko and mmcsd.ko need to be a matching pair built from the 964 same source (previously, the dependency of mmcsd.ko on mmc.ko was 965 missing, but mmcsd.ko now will refuse to load if it is incompatible 966 with mmc.ko). 967 96820170315: 969 The syntax of ipfw(8) named states was changed to avoid ambiguity. 970 If you have used named states in the firewall rules, you need to modify 971 them after installworld and before rebooting. Now named states must 972 be prefixed with colon. 973 97420170311: 975 The old drm (sys/dev/drm/) drivers for i915 and radeon have been 976 removed as the userland we provide cannot use them. The KMS version 977 (sys/dev/drm2) supports the same hardware. 978 97920170302: 980 Clang, llvm, lldb, compiler-rt and libc++ have been upgraded to 4.0.0. 981 Please see the 20141231 entry below for information about prerequisites 982 and upgrading, if you are not already using clang 3.5.0 or higher. 983 98420170221: 985 The code that provides support for ZFS .zfs/ directory functionality 986 has been reimplemented. It's not possible now to create a snapshot 987 by mkdir under .zfs/snapshot/. That should be the only user visible 988 change. 989 99020170216: 991 EISA bus support has been removed. The WITH_EISA option is no longer 992 valid. 993 99420170215: 995 MCA bus support has been removed. 996 99720170127: 998 The WITH_LLD_AS_LD / WITHOUT_LLD_AS_LD build knobs have been renamed 999 WITH_LLD_IS_LD / WITHOUT_LLD_IS_LD, for consistency with CLANG_IS_CC. 1000 100120170112: 1002 The EM_MULTIQUEUE kernel configuration option is deprecated now that 1003 the em(4) driver conforms to iflib specifications. 1004 100520170109: 1006 The igb(4), em(4) and lem(4) ethernet drivers are now implemented via 1007 IFLIB. If you have a custom kernel configuration that excludes em(4) 1008 but you use igb(4), you need to re-add em(4) to your custom 1009 configuration. 1010 101120161217: 1012 Clang, llvm, lldb, compiler-rt and libc++ have been upgraded to 3.9.1. 1013 Please see the 20141231 entry below for information about prerequisites 1014 and upgrading, if you are not already using clang 3.5.0 or higher. 1015 101620161124: 1017 Clang, llvm, lldb, compiler-rt and libc++ have been upgraded to 3.9.0. 1018 Please see the 20141231 entry below for information about prerequisites 1019 and upgrading, if you are not already using clang 3.5.0 or higher. 1020 102120161119: 1022 The layout of the pmap structure has changed for powerpc to put the pmap 1023 statistics at the front for all CPU variations. libkvm(3) and all tools 1024 that link against it need to be recompiled. 1025 102620161030: 1027 isl(4) and cyapa(4) drivers now require a new driver, 1028 chromebook_platform(4), to work properly on Chromebook-class hardware. 1029 On other types of hardware the drivers may need to be configured using 1030 device hints. Please see the corresponding manual pages for details. 1031 103220161017: 1033 The urtwn(4) driver was merged into rtwn(4) and now consists of 1034 rtwn(4) main module + rtwn_usb(4) and rtwn_pci(4) bus-specific 1035 parts. 1036 Also, firmware for RTL8188CE was renamed due to possible name 1037 conflict (rtwnrtl8192cU(B) -> rtwnrtl8192cE(B)) 1038 103920161015: 1040 GNU rcs has been removed from base. It is available as packages: 1041 - rcs: Latest GPLv3 GNU rcs version. 1042 - rcs57: Copy of the latest version of GNU rcs (GPLv2) before it was 1043 removed from base. 1044 104520161008: 1046 Use of the cc_cdg, cc_chd, cc_hd, or cc_vegas congestion control 1047 modules now requires that the kernel configuration contain the 1048 TCP_HHOOK option. (This option is included in the GENERIC kernel.) 1049 105020161003: 1051 The WITHOUT_ELFCOPY_AS_OBJCOPY src.conf(5) knob has been retired. 1052 ELF Tool Chain's elfcopy is always installed as /usr/bin/objcopy. 1053 105420160924: 1055 Relocatable object files with the extension of .So have been renamed 1056 to use an extension of .pico instead. The purpose of this change is 1057 to avoid a name clash with shared libraries on case-insensitive file 1058 systems. On those file systems, foo.So is the same file as foo.so. 1059 106020160918: 1061 GNU rcs has been turned off by default. It can (temporarily) be built 1062 again by adding WITH_RCS knob in src.conf. 1063 Otherwise, GNU rcs is available from packages: 1064 - rcs: Latest GPLv3 GNU rcs version. 1065 - rcs57: Copy of the latest version of GNU rcs (GPLv2) from base. 1066 106720160918: 1068 The backup_uses_rcs functionality has been removed from rc.subr. 1069 107020160908: 1071 The queue(3) debugging macro, QUEUE_MACRO_DEBUG, has been split into 1072 two separate components, QUEUE_MACRO_DEBUG_TRACE and 1073 QUEUE_MACRO_DEBUG_TRASH. Define both for the original 1074 QUEUE_MACRO_DEBUG behavior. 1075 107620160824: 1077 r304787 changed some ioctl interfaces between the iSCSI userspace 1078 programs and the kernel. ctladm, ctld, iscsictl, and iscsid must be 1079 rebuilt to work with new kernels. __FreeBSD_version has been bumped 1080 to 1200005. 1081 108220160818: 1083 The UDP receive code has been updated to only treat incoming UDP 1084 packets that were addressed to an L2 broadcast address as L3 1085 broadcast packets. It is not expected that this will affect any 1086 standards-conforming UDP application. The new behaviour can be 1087 disabled by setting the sysctl net.inet.udp.require_l2_bcast to 1088 0. 1089 109020160818: 1091 Remove the openbsd_poll system call. 1092 __FreeBSD_version has been bumped because of this. 1093 109420160708: 1095 The stable/11 branch has been created from head@r302406. 1096 109720160622: 1098 The libc stub for the pipe(2) system call has been replaced with 1099 a wrapper that calls the pipe2(2) system call and the pipe(2) 1100 system call is now only implemented by the kernels that include 1101 "options COMPAT_FREEBSD10" in their config file (this is the 1102 default). Users should ensure that this option is enabled in 1103 their kernel or upgrade userspace to r302092 before upgrading their 1104 kernel. 1105 110620160527: 1107 CAM will now strip leading spaces from SCSI disks' serial numbers. 1108 This will affect users who create UFS filesystems on SCSI disks using 1109 those disk's diskid device nodes. For example, if /etc/fstab 1110 previously contained a line like 1111 "/dev/diskid/DISK-%20%20%20%20%20%20%20ABCDEFG0123456", you should 1112 change it to "/dev/diskid/DISK-ABCDEFG0123456". Users of geom 1113 transforms like gmirror may also be affected. ZFS users should 1114 generally be fine. 1115 111620160523: 1117 The bitstring(3) API has been updated with new functionality and 1118 improved performance. But it is binary-incompatible with the old API. 1119 Objects built with the new headers may not be linked against objects 1120 built with the old headers. 1121 112220160520: 1123 The brk and sbrk functions have been removed from libc on arm64. 1124 Binutils from ports has been updated to not link to these 1125 functions and should be updated to the latest version before 1126 installing a new libc. 1127 112820160517: 1129 The armv6 port now defaults to hard float ABI. Limited support 1130 for running both hardfloat and soft float on the same system 1131 is available using the libraries installed with -DWITH_LIBSOFT. 1132 This has only been tested as an upgrade path for installworld 1133 and packages may fail or need manual intervention to run. New 1134 packages will be needed. 1135 1136 To update an existing self-hosted armv6hf system, you must add 1137 TARGET_ARCH=armv6 on the make command line for both the build 1138 and the install steps. 1139 114020160510: 1141 Kernel modules compiled outside of a kernel build now default to 1142 installing to /boot/modules instead of /boot/kernel. Many kernel 1143 modules built this way (such as those in ports) already overrode 1144 KMODDIR explicitly to install into /boot/modules. However, 1145 manually building and installing a module from /sys/modules will 1146 now install to /boot/modules instead of /boot/kernel. 1147 114820160414: 1149 The CAM I/O scheduler has been committed to the kernel. There should be 1150 no user visible impact. This does enable NCQ Trim on ada SSDs. While the 1151 list of known rogues that claim support for this but actually corrupt 1152 data is believed to be complete, be on the lookout for data 1153 corruption. The known rogue list is believed to be complete: 1154 1155 o Crucial MX100, M550 drives with MU01 firmware. 1156 o Micron M510 and M550 drives with MU01 firmware. 1157 o Micron M500 prior to MU07 firmware 1158 o Samsung 830, 840, and 850 all firmwares 1159 o FCCT M500 all firmwares 1160 1161 Crucial has firmware http://www.crucial.com/usa/en/support-ssd-firmware 1162 with working NCQ TRIM. For Micron branded drives, see your sales rep for 1163 updated firmware. Black listed drives will work correctly because these 1164 drives work correctly so long as no NCQ TRIMs are sent to them. Given 1165 this list is the same as found in Linux, it's believed there are no 1166 other rogues in the market place. All other models from the above 1167 vendors work. 1168 1169 To be safe, if you are at all concerned, you can quirk each of your 1170 drives to prevent NCQ from being sent by setting: 1171 kern.cam.ada.X.quirks="0x2" 1172 in loader.conf. If the drive requires the 4k sector quirk, set the 1173 quirks entry to 0x3. 1174 117520160330: 1176 The FAST_DEPEND build option has been removed and its functionality is 1177 now the one true way. The old mkdep(1) style of 'make depend' has 1178 been removed. See 20160311 for further details. 1179 118020160317: 1181 Resource range types have grown from unsigned long to uintmax_t. All 1182 drivers, and anything using libdevinfo, need to be recompiled. 1183 118420160311: 1185 WITH_FAST_DEPEND is now enabled by default for in-tree and out-of-tree 1186 builds. It no longer runs mkdep(1) during 'make depend', and the 1187 'make depend' stage can safely be skipped now as it is auto ran 1188 when building 'make all' and will generate all SRCS and DPSRCS before 1189 building anything else. Dependencies are gathered at compile time with 1190 -MF flags kept in separate .depend files per object file. Users should 1191 run 'make cleandepend' once if using -DNO_CLEAN to clean out older 1192 stale .depend files. 1193 119420160306: 1195 On amd64, clang 3.8.0 can now insert sections of type AMD64_UNWIND into 1196 kernel modules. Therefore, if you load any kernel modules at boot time, 1197 please install the boot loaders after you install the kernel, but before 1198 rebooting, e.g.: 1199 1200 make buildworld 1201 make buildkernel KERNCONF=YOUR_KERNEL_HERE 1202 make installkernel KERNCONF=YOUR_KERNEL_HERE 1203 make -C sys/boot install 1204 <reboot in single user> 1205 1206 Then follow the usual steps, described in the General Notes section, 1207 below. 1208 120920160305: 1210 Clang, llvm, lldb and compiler-rt have been upgraded to 3.8.0. Please 1211 see the 20141231 entry below for information about prerequisites and 1212 upgrading, if you are not already using clang 3.5.0 or higher. 1213 121420160301: 1215 The AIO subsystem is now a standard part of the kernel. The 1216 VFS_AIO kernel option and aio.ko kernel module have been removed. 1217 Due to stability concerns, asynchronous I/O requests are only 1218 permitted on sockets and raw disks by default. To enable 1219 asynchronous I/O requests on all file types, set the 1220 vfs.aio.enable_unsafe sysctl to a non-zero value. 1221 122220160226: 1223 The ELF object manipulation tool objcopy is now provided by the 1224 ELF Tool Chain project rather than by GNU binutils. It should be a 1225 drop-in replacement, with the addition of arm64 support. The 1226 (temporary) src.conf knob WITHOUT_ELFCOPY_AS_OBJCOPY knob may be set 1227 to obtain the GNU version if necessary. 1228 122920160129: 1230 Building ZFS pools on top of zvols is prohibited by default. That 1231 feature has never worked safely; it's always been prone to deadlocks. 1232 Using a zvol as the backing store for a VM guest's virtual disk will 1233 still work, even if the guest is using ZFS. Legacy behavior can be 1234 restored by setting vfs.zfs.vol.recursive=1. 1235 123620160119: 1237 The NONE and HPN patches has been removed from OpenSSH. They are 1238 still available in the security/openssh-portable port. 1239 124020160113: 1241 With the addition of ypldap(8), a new _ypldap user is now required 1242 during installworld. "mergemaster -p" can be used to add the user 1243 prior to installworld, as documented in the handbook. 1244 124520151216: 1246 The tftp loader (pxeboot) now uses the option root-path directive. As a 1247 consequence it no longer looks for a pxeboot.4th file on the tftp 1248 server. Instead it uses the regular /boot infrastructure as with the 1249 other loaders. 1250 125120151211: 1252 The code to start recording plug and play data into the modules has 1253 been committed. While the old tools will properly build a new kernel, 1254 a number of warnings about "unknown metadata record 4" will be produced 1255 for an older kldxref. To avoid such warnings, make sure to rebuild 1256 the kernel toolchain (or world). Make sure that you have r292078 or 1257 later when trying to build 292077 or later before rebuilding. 1258 125920151207: 1260 Debug data files are now built by default with 'make buildworld' and 1261 installed with 'make installworld'. This facilitates debugging but 1262 requires more disk space both during the build and for the installed 1263 world. Debug files may be disabled by setting WITHOUT_DEBUG_FILES=yes 1264 in src.conf(5). 1265 126620151130: 1267 r291527 changed the internal interface between the nfsd.ko and 1268 nfscommon.ko modules. As such, they must both be upgraded to-gether. 1269 __FreeBSD_version has been bumped because of this. 1270 127120151108: 1272 Add support for unicode collation strings leads to a change of 1273 order of files listed by ls(1) for example. To get back to the old 1274 behaviour, set LC_COLLATE environment variable to "C". 1275 1276 Databases administrators will need to reindex their databases given 1277 collation results will be different. 1278 1279 Due to a bug in install(1) it is recommended to remove the ancient 1280 locales before running make installworld. 1281 1282 rm -rf /usr/share/locale/* 1283 128420151030: 1285 The OpenSSL has been upgraded to 1.0.2d. Any binaries requiring 1286 libcrypto.so.7 or libssl.so.7 must be recompiled. 1287 128820151020: 1289 Qlogic 24xx/25xx firmware images were updated from 5.5.0 to 7.3.0. 1290 Kernel modules isp_2400_multi and isp_2500_multi were removed and 1291 should be replaced with isp_2400 and isp_2500 modules respectively. 1292 129320151017: 1294 The build previously allowed using 'make -n' to not recurse into 1295 sub-directories while showing what commands would be executed, and 1296 'make -n -n' to recursively show commands. Now 'make -n' will recurse 1297 and 'make -N' will not. 1298 129920151012: 1300 If you specify SENDMAIL_MC or SENDMAIL_CF in make.conf, mergemaster 1301 and etcupdate will now use this file. A custom sendmail.cf is now 1302 updated via this mechanism rather than via installworld. If you had 1303 excluded sendmail.cf in mergemaster.rc or etcupdate.conf, you may 1304 want to remove the exclusion or change it to "always install". 1305 /etc/mail/sendmail.cf is now managed the same way regardless of 1306 whether SENDMAIL_MC/SENDMAIL_CF is used. If you are not using 1307 SENDMAIL_MC/SENDMAIL_CF there should be no change in behavior. 1308 130920151011: 1310 Compatibility shims for legacy ATA device names have been removed. 1311 It includes ATA_STATIC_ID kernel option, kern.cam.ada.legacy_aliases 1312 and kern.geom.raid.legacy_aliases loader tunables, kern.devalias.* 1313 environment variables, /dev/ad* and /dev/ar* symbolic links. 1314 131520151006: 1316 Clang, llvm, lldb, compiler-rt and libc++ have been upgraded to 3.7.0. 1317 Please see the 20141231 entry below for information about prerequisites 1318 and upgrading, if you are not already using clang 3.5.0 or higher. 1319 132020150924: 1321 Kernel debug files have been moved to /usr/lib/debug/boot/kernel/, 1322 and renamed from .symbols to .debug. This reduces the size requirements 1323 on the boot partition or file system and provides consistency with 1324 userland debug files. 1325 1326 When using the supported kernel installation method the 1327 /usr/lib/debug/boot/kernel directory will be renamed (to kernel.old) 1328 as is done with /boot/kernel. 1329 1330 Developers wishing to maintain the historical behavior of installing 1331 debug files in /boot/kernel/ can set KERN_DEBUGDIR="" in src.conf(5). 1332 133320150827: 1334 The wireless drivers had undergone changes that remove the 'parent 1335 interface' from the ifconfig -l output. The rc.d network scripts 1336 used to check presence of a parent interface in the list, so old 1337 scripts would fail to start wireless networking. Thus, etcupdate(3) 1338 or mergemaster(8) run is required after kernel update, to update your 1339 rc.d scripts in /etc. 1340 134120150827: 1342 pf no longer supports 'scrub fragment crop' or 'scrub fragment drop-ovl' 1343 These configurations are now automatically interpreted as 1344 'scrub fragment reassemble'. 1345 134620150817: 1347 Kernel-loadable modules for the random(4) device are back. To use 1348 them, the kernel must have 1349 1350 device random 1351 options RANDOM_LOADABLE 1352 1353 kldload(8) can then be used to load random_fortuna.ko 1354 or random_yarrow.ko. Please note that due to the indirect 1355 function calls that the loadable modules need to provide, 1356 the build-in variants will be slightly more efficient. 1357 1358 The random(4) kernel option RANDOM_DUMMY has been retired due to 1359 unpopularity. It was not all that useful anyway. 1360 136120150813: 1362 The WITHOUT_ELFTOOLCHAIN_TOOLS src.conf(5) knob has been retired. 1363 Control over building the ELF Tool Chain tools is now provided by 1364 the WITHOUT_TOOLCHAIN knob. 1365 136620150810: 1367 The polarity of Pulse Per Second (PPS) capture events with the 1368 uart(4) driver has been corrected. Prior to this change the PPS 1369 "assert" event corresponded to the trailing edge of a positive PPS 1370 pulse and the "clear" event was the leading edge of the next pulse. 1371 1372 As the width of a PPS pulse in a typical GPS receiver is on the 1373 order of 1 millisecond, most users will not notice any significant 1374 difference with this change. 1375 1376 Anyone who has compensated for the historical polarity reversal by 1377 configuring a negative offset equal to the pulse width will need to 1378 remove that workaround. 1379 138020150809: 1381 The default group assigned to /dev/dri entries has been changed 1382 from 'wheel' to 'video' with the id of '44'. If you want to have 1383 access to the dri devices please add yourself to the video group 1384 with: 1385 1386 # pw groupmod video -m $USER 1387 138820150806: 1389 The menu.rc and loader.rc files will now be replaced during 1390 upgrades. Please migrate local changes to menu.rc.local and 1391 loader.rc.local instead. 1392 139320150805: 1394 GNU Binutils versions of addr2line, c++filt, nm, readelf, size, 1395 strings and strip have been removed. The src.conf(5) knob 1396 WITHOUT_ELFTOOLCHAIN_TOOLS no longer provides the binutils tools. 1397 139820150728: 1399 As ZFS requires more kernel stack pages than is the default on some 1400 architectures e.g. i386, it now warns if KSTACK_PAGES is less than 1401 ZFS_MIN_KSTACK_PAGES (which is 4 at the time of writing). 1402 1403 Please consider using 'options KSTACK_PAGES=X' where X is greater 1404 than or equal to ZFS_MIN_KSTACK_PAGES i.e. 4 in such configurations. 1405 140620150706: 1407 sendmail has been updated to 8.15.2. Starting with FreeBSD 11.0 1408 and sendmail 8.15, sendmail uses uncompressed IPv6 addresses by 1409 default, i.e., they will not contain "::". For example, instead 1410 of ::1, it will be 0:0:0:0:0:0:0:1. This permits a zero subnet 1411 to have a more specific match, such as different map entries for 1412 IPv6:0:0 vs IPv6:0. This change requires that configuration 1413 data (including maps, files, classes, custom ruleset, etc.) must 1414 use the same format, so make certain such configuration data is 1415 upgrading. As a very simple check search for patterns like 1416 'IPv6:[0-9a-fA-F:]*::' and 'IPv6::'. To return to the old 1417 behavior, set the m4 option confUSE_COMPRESSED_IPV6_ADDRESSES or 1418 the cf option UseCompressedIPv6Addresses. 1419 142020150630: 1421 The default kernel entropy-processing algorithm is now 1422 Fortuna, replacing Yarrow. 1423 1424 Assuming you have 'device random' in your kernel config 1425 file, the configurations allow a kernel option to override 1426 this default. You may choose *ONE* of: 1427 1428 options RANDOM_YARROW # Legacy /dev/random algorithm. 1429 options RANDOM_DUMMY # Blocking-only driver. 1430 1431 If you have neither, you get Fortuna. For most people, 1432 read no further, Fortuna will give a /dev/random that works 1433 like it always used to, and the difference will be irrelevant. 1434 1435 If you remove 'device random', you get *NO* kernel-processed 1436 entropy at all. This may be acceptable to folks building 1437 embedded systems, but has complications. Carry on reading, 1438 and it is assumed you know what you need. 1439 1440 *PLEASE* read random(4) and random(9) if you are in the 1441 habit of tweaking kernel configs, and/or if you are a member 1442 of the embedded community, wanting specific and not-usual 1443 behaviour from your security subsystems. 1444 1445 NOTE!! If you use RANDOM_DUMMY and/or have no 'device 1446 random', you will NOT have a functioning /dev/random, and 1447 many cryptographic features will not work, including SSH. 1448 You may also find strange behaviour from the random(3) set 1449 of library functions, in particular sranddev(3), srandomdev(3) 1450 and arc4random(3). The reason for this is that the KERN_ARND 1451 sysctl only returns entropy if it thinks it has some to 1452 share, and with RANDOM_DUMMY or no 'device random' this 1453 will never happen. 1454 145520150623: 1456 An additional fix for the issue described in the 20150614 sendmail 1457 entry below has been committed in revision 284717. 1458 145920150616: 1460 FreeBSD's old make (fmake) has been removed from the system. It is 1461 available as the devel/fmake port or via pkg install fmake. 1462 146320150615: 1464 The fix for the issue described in the 20150614 sendmail entry 1465 below has been committed in revision 284436. The work 1466 around described in that entry is no longer needed unless the 1467 default setting is overridden by a confDH_PARAMETERS configuration 1468 setting of '5' or pointing to a 512 bit DH parameter file. 1469 147020150614: 1471 ALLOW_DEPRECATED_ATF_TOOLS/ATFFILE support has been removed from 1472 atf.test.mk (included from bsd.test.mk). Please upgrade devel/atf 1473 and devel/kyua to version 0.20+ and adjust any calling code to work 1474 with Kyuafile and kyua. 1475 147620150614: 1477 The import of openssl to address the FreeBSD-SA-15:10.openssl 1478 security advisory includes a change which rejects handshakes 1479 with DH parameters below 768 bits. sendmail releases prior 1480 to 8.15.2 (not yet released), defaulted to a 512 bit 1481 DH parameter setting for client connections. To work around 1482 this interoperability, sendmail can be configured to use a 1483 2048 bit DH parameter by: 1484 1485 1. Edit /etc/mail/`hostname`.mc 1486 2. If a setting for confDH_PARAMETERS does not exist or 1487 exists and is set to a string beginning with '5', 1488 replace it with '2'. 1489 3. If a setting for confDH_PARAMETERS exists and is set to 1490 a file path, create a new file with: 1491 openssl dhparam -out /path/to/file 2048 1492 4. Rebuild the .cf file: 1493 cd /etc/mail/; make; make install 1494 5. Restart sendmail: 1495 cd /etc/mail/; make restart 1496 1497 A sendmail patch is coming, at which time this file will be 1498 updated. 1499 150020150604: 1501 Generation of legacy formatted entries have been disabled by default 1502 in pwd_mkdb(8), as all base system consumers of the legacy formatted 1503 entries were converted to use the new format by default when the new, 1504 machine independent format have been added and supported since FreeBSD 1505 5.x. 1506 1507 Please see the pwd_mkdb(8) manual page for further details. 1508 150920150525: 1510 Clang and llvm have been upgraded to 3.6.1 release. Please see the 1511 20141231 entry below for information about prerequisites and upgrading, 1512 if you are not already using 3.5.0 or higher. 1513 151420150521: 1515 TI platform code switched to using vendor DTS files and this update 1516 may break existing systems running on Beaglebone, Beaglebone Black, 1517 and Pandaboard: 1518 1519 - dtb files should be regenerated/reinstalled. Filenames are the 1520 same but content is different now 1521 - GPIO addressing was changed, now each GPIO bank (32 pins per bank) 1522 has its own /dev/gpiocX device, e.g. pin 121 on /dev/gpioc0 in old 1523 addressing scheme is now pin 25 on /dev/gpioc3. 1524 - Pandaboard: /etc/ttys should be updated, serial console device is 1525 now /dev/ttyu2, not /dev/ttyu0 1526 152720150501: 1528 soelim(1) from gnu/usr.bin/groff has been replaced by usr.bin/soelim. 1529 If you need the GNU extension from groff soelim(1), install groff 1530 from package: pkg install groff, or via ports: textproc/groff. 1531 153220150423: 1533 chmod, chflags, chown and chgrp now affect symlinks in -R mode as 1534 defined in symlink(7); previously symlinks were silently ignored. 1535 153620150415: 1537 The const qualifier has been removed from iconv(3) to comply with 1538 POSIX. The ports tree is aware of this from r384038 onwards. 1539 154020150416: 1541 Libraries specified by LIBADD in Makefiles must have a corresponding 1542 DPADD_<lib> variable to ensure correct dependencies. This is now 1543 enforced in src.libnames.mk. 1544 154520150324: 1546 From legacy ata(4) driver was removed support for SATA controllers 1547 supported by more functional drivers ahci(4), siis(4) and mvs(4). 1548 Kernel modules ataahci and ataadaptec were removed completely, 1549 replaced by ahci and mvs modules respectively. 1550 155120150315: 1552 Clang, llvm and lldb have been upgraded to 3.6.0 release. Please see 1553 the 20141231 entry below for information about prerequisites and 1554 upgrading, if you are not already using 3.5.0 or higher. 1555 155620150307: 1557 The 32-bit PowerPC kernel has been changed to a position-independent 1558 executable. This can only be booted with a version of loader(8) 1559 newer than January 31, 2015, so make sure to update both world and 1560 kernel before rebooting. 1561 156220150217: 1563 If you are running a -CURRENT kernel since r273872 (Oct 30th, 2014), 1564 but before r278950, the RNG was not seeded properly. Immediately 1565 upgrade the kernel to r278950 or later and regenerate any keys (e.g. 1566 ssh keys or openssl keys) that were generated w/ a kernel from that 1567 range. This does not affect programs that directly used /dev/random 1568 or /dev/urandom. All userland uses of arc4random(3) are affected. 1569 157020150210: 1571 The autofs(4) ABI was changed in order to restore binary compatibility 1572 with 10.1-RELEASE. The automountd(8) daemon needs to be rebuilt to work 1573 with the new kernel. 1574 157520150131: 1576 The powerpc64 kernel has been changed to a position-independent 1577 executable. This can only be booted with a new version of loader(8), 1578 so make sure to update both world and kernel before rebooting. 1579 158020150118: 1581 Clang and llvm have been upgraded to 3.5.1 release. This is a bugfix 1582 only release, no new features have been added. Please see the 20141231 1583 entry below for information about prerequisites and upgrading, if you 1584 are not already using 3.5.0. 1585 158620150107: 1587 ELF tools addr2line, elfcopy (strip), nm, size, and strings are now 1588 taken from the ELF Tool Chain project rather than GNU binutils. They 1589 should be drop-in replacements, with the addition of arm64 support. 1590 The WITHOUT_ELFTOOLCHAIN_TOOLS= knob may be used to obtain the 1591 binutils tools, if necessary. See 20150805 for updated information. 1592 159320150105: 1594 The default Unbound configuration now enables remote control 1595 using a local socket. Users who have already enabled the 1596 local_unbound service should regenerate their configuration 1597 by running "service local_unbound setup" as root. 1598 159920150102: 1600 The GNU texinfo and GNU info pages have been removed. 1601 To be able to view GNU info pages please install texinfo from ports. 1602 160320141231: 1604 Clang, llvm and lldb have been upgraded to 3.5.0 release. 1605 1606 As of this release, a prerequisite for building clang, llvm and lldb is 1607 a C++11 capable compiler and C++11 standard library. This means that to 1608 be able to successfully build the cross-tools stage of buildworld, with 1609 clang as the bootstrap compiler, your system compiler or cross compiler 1610 should either be clang 3.3 or later, or gcc 4.8 or later, and your 1611 system C++ library should be libc++, or libdstdc++ from gcc 4.8 or 1612 later. 1613 1614 On any standard FreeBSD 10.x or 11.x installation, where clang and 1615 libc++ are on by default (that is, on x86 or arm), this should work out 1616 of the box. 1617 1618 On 9.x installations where clang is enabled by default, e.g. on x86 and 1619 powerpc, libc++ will not be enabled by default, so libc++ should be 1620 built (with clang) and installed first. If both clang and libc++ are 1621 missing, build clang first, then use it to build libc++. 1622 1623 On 8.x and earlier installations, upgrade to 9.x first, and then follow 1624 the instructions for 9.x above. 1625 1626 Sparc64 and mips users are unaffected, as they still use gcc 4.2.1 by 1627 default, and do not build clang. 1628 1629 Many embedded systems are resource constrained, and will not be able to 1630 build clang in a reasonable time, or in some cases at all. In those 1631 cases, cross building bootable systems on amd64 is a workaround. 1632 1633 This new version of clang introduces a number of new warnings, of which 1634 the following are most likely to appear: 1635 1636 -Wabsolute-value 1637 1638 This warns in two cases, for both C and C++: 1639 * When the code is trying to take the absolute value of an unsigned 1640 quantity, which is effectively a no-op, and almost never what was 1641 intended. The code should be fixed, if at all possible. If you are 1642 sure that the unsigned quantity can be safely cast to signed, without 1643 loss of information or undefined behavior, you can add an explicit 1644 cast, or disable the warning. 1645 1646 * When the code is trying to take an absolute value, but the called 1647 abs() variant is for the wrong type, which can lead to truncation. 1648 If you want to disable the warning instead of fixing the code, please 1649 make sure that truncation will not occur, or it might lead to unwanted 1650 side-effects. 1651 1652 -Wtautological-undefined-compare and 1653 -Wundefined-bool-conversion 1654 1655 These warn when C++ code is trying to compare 'this' against NULL, while 1656 'this' should never be NULL in well-defined C++ code. However, there is 1657 some legacy (pre C++11) code out there, which actively abuses this 1658 feature, which was less strictly defined in previous C++ versions. 1659 1660 Squid and openjdk do this, for example. The warning can be turned off 1661 for C++98 and earlier, but compiling the code in C++11 mode might result 1662 in unexpected behavior; for example, the parts of the program that are 1663 unreachable could be optimized away. 1664 166520141222: 1666 The old NFS client and server (kernel options NFSCLIENT, NFSSERVER) 1667 kernel sources have been removed. The .h files remain, since some 1668 utilities include them. This will need to be fixed later. 1669 If "mount -t oldnfs ..." is attempted, it will fail. 1670 If the "-o" option on mountd(8), nfsd(8) or nfsstat(1) is used, 1671 the utilities will report errors. 1672 167320141121: 1674 The handling of LOCAL_LIB_DIRS has been altered to skip addition of 1675 directories to top level SUBDIR variable when their parent 1676 directory is included in LOCAL_DIRS. Users with build systems with 1677 such hierarchies and without SUBDIR entries in the parent 1678 directory Makefiles should add them or add the directories to 1679 LOCAL_DIRS. 1680 168120141109: 1682 faith(4) and faithd(8) have been removed from the base system. Faith 1683 has been obsolete for a very long time. 1684 168520141104: 1686 vt(4), the new console driver, is enabled by default. It brings 1687 support for Unicode and double-width characters, as well as 1688 support for UEFI and integration with the KMS kernel video 1689 drivers. 1690 1691 You may need to update your console settings in /etc/rc.conf, 1692 most probably the keymap. During boot, /etc/rc.d/syscons will 1693 indicate what you need to do. 1694 1695 vt(4) still has issues and lacks some features compared to 1696 syscons(4). See the wiki for up-to-date information: 1697 https://wiki.freebsd.org/Newcons 1698 1699 If you want to keep using syscons(4), you can do so by adding 1700 the following line to /boot/loader.conf: 1701 kern.vty=sc 1702 170320141102: 1704 pjdfstest has been integrated into kyua as an opt-in test suite. 1705 Please see share/doc/pjdfstest/README for more details on how to 1706 execute it. 1707 170820141009: 1709 gperf has been removed from the base system for architectures 1710 that use clang. Ports that require gperf will obtain it from the 1711 devel/gperf port. 1712 171320140923: 1714 pjdfstest has been moved from tools/regression/pjdfstest to 1715 contrib/pjdfstest . 1716 171720140922: 1718 At svn r271982, The default linux compat kernel ABI has been adjusted 1719 to 2.6.18 in support of the linux-c6 compat ports infrastructure 1720 update. If you wish to continue using the linux-f10 compat ports, 1721 add compat.linux.osrelease=2.6.16 to your local sysctl.conf. Users are 1722 encouraged to update their linux-compat packages to linux-c6 during 1723 their next update cycle. 1724 172520140729: 1726 The ofwfb driver, used to provide a graphics console on PowerPC when 1727 using vt(4), no longer allows mmap() of all physical memory. This 1728 will prevent Xorg on PowerPC with some ATI graphics cards from 1729 initializing properly unless x11-servers/xorg-server is updated to 1730 1.12.4_8 or newer. 1731 173220140723: 1733 The xdev targets have been converted to using TARGET and 1734 TARGET_ARCH instead of XDEV and XDEV_ARCH. 1735 173620140719: 1737 The default unbound configuration has been modified to address 1738 issues with reverse lookups on networks that use private 1739 address ranges. If you use the local_unbound service, run 1740 "service local_unbound setup" as root to regenerate your 1741 configuration, then "service local_unbound reload" to load the 1742 new configuration. 1743 174420140709: 1745 The GNU texinfo and GNU info pages are not built and installed 1746 anymore, WITH_INFO knob has been added to allow to built and install 1747 them again. 1748 UPDATE: see 20150102 entry on texinfo's removal 1749 175020140708: 1751 The GNU readline library is now an INTERNALLIB - that is, it is 1752 statically linked into consumers (GDB and variants) in the base 1753 system, and the shared library is no longer installed. The 1754 devel/readline port is available for third party software that 1755 requires readline. 1756 175720140702: 1758 The Itanium architecture (ia64) has been removed from the list of 1759 known architectures. This is the first step in the removal of the 1760 architecture. 1761 176220140701: 1763 Commit r268115 has added NFSv4.1 server support, merged from 1764 projects/nfsv4.1-server. Since this includes changes to the 1765 internal interfaces between the NFS related modules, a full 1766 build of the kernel and modules will be necessary. 1767 __FreeBSD_version has been bumped. 1768 176920140629: 1770 The WITHOUT_VT_SUPPORT kernel config knob has been renamed 1771 WITHOUT_VT. (The other _SUPPORT knobs have a consistent meaning 1772 which differs from the behaviour controlled by this knob.) 1773 177420140619: 1775 Maximal length of the serial number in CTL was increased from 16 to 1776 64 chars, that breaks ABI. All CTL-related tools, such as ctladm 1777 and ctld, need to be rebuilt to work with a new kernel. 1778 177920140606: 1780 The libatf-c and libatf-c++ major versions were downgraded to 0 and 1781 1 respectively to match the upstream numbers. They were out of 1782 sync because, when they were originally added to FreeBSD, the 1783 upstream versions were not respected. These libraries are private 1784 and not yet built by default, so renumbering them should be a 1785 non-issue. However, unclean source trees will yield broken test 1786 programs once the operator executes "make delete-old-libs" after a 1787 "make installworld". 1788 1789 Additionally, the atf-sh binary was made private by moving it into 1790 /usr/libexec/. Already-built shell test programs will keep the 1791 path to the old binary so they will break after "make delete-old" 1792 is run. 1793 1794 If you are using WITH_TESTS=yes (not the default), wipe the object 1795 tree and rebuild from scratch to prevent spurious test failures. 1796 This is only needed once: the misnumbered libraries and misplaced 1797 binaries have been added to OptionalObsoleteFiles.inc so they will 1798 be removed during a clean upgrade. 1799 180020140512: 1801 Clang and llvm have been upgraded to 3.4.1 release. 1802 180320140508: 1804 We bogusly installed src.opts.mk in /usr/share/mk. This file should 1805 be removed to avoid issues in the future (and has been added to 1806 ObsoleteFiles.inc). 1807 180820140505: 1809 /etc/src.conf now affects only builds of the FreeBSD src tree. In the 1810 past, it affected all builds that used the bsd.*.mk files. The old 1811 behavior was a bug, but people may have relied upon it. To get this 1812 behavior back, you can .include /etc/src.conf from /etc/make.conf 1813 (which is still global and isn't changed). This also changes the 1814 behavior of incremental builds inside the tree of individual 1815 directories. Set MAKESYSPATH to ".../share/mk" to do that. 1816 Although this has survived make universe and some upgrade scenarios, 1817 other upgrade scenarios may have broken. At least one form of 1818 temporary breakage was fixed with MAKESYSPATH settings for buildworld 1819 as well... In cases where MAKESYSPATH isn't working with this 1820 setting, you'll need to set it to the full path to your tree. 1821 1822 One side effect of all this cleaning up is that bsd.compiler.mk 1823 is no longer implicitly included by bsd.own.mk. If you wish to 1824 use COMPILER_TYPE, you must now explicitly include bsd.compiler.mk 1825 as well. 1826 182720140430: 1828 The lindev device has been removed since /dev/full has been made a 1829 standard device. __FreeBSD_version has been bumped. 1830 183120140424: 1832 The knob WITHOUT_VI was added to the base system, which controls 1833 building ex(1), vi(1), etc. Older releases of FreeBSD required ex(1) 1834 in order to reorder files share/termcap and didn't build ex(1) as a 1835 build tool, so building/installing with WITH_VI is highly advised for 1836 build hosts for older releases. 1837 1838 This issue has been fixed in stable/9 and stable/10 in r277022 and 1839 r276991, respectively. 1840 184120140418: 1842 The YES_HESIOD knob has been removed. It has been obsolete for 1843 a decade. Please move to using WITH_HESIOD instead or your builds 1844 will silently lack HESIOD. 1845 184620140405: 1847 The uart(4) driver has been changed with respect to its handling 1848 of the low-level console. Previously the uart(4) driver prevented 1849 any process from changing the baudrate or the CLOCAL and HUPCL 1850 control flags. By removing the restrictions, operators can make 1851 changes to the serial console port without having to reboot. 1852 However, when getty(8) is started on the serial device that is 1853 associated with the low-level console, a misconfigured terminal 1854 line in /etc/ttys will now have a real impact. 1855 Before upgrading the kernel, make sure that /etc/ttys has the 1856 serial console device configured as 3wire without baudrate to 1857 preserve the previous behaviour. E.g: 1858 ttyu0 "/usr/libexec/getty 3wire" vt100 on secure 1859 186020140306: 1861 Support for libwrap (TCP wrappers) in rpcbind was disabled by default 1862 to improve performance. To re-enable it, if needed, run rpcbind 1863 with command line option -W. 1864 186520140226: 1866 Switched back to the GPL dtc compiler due to updates in the upstream 1867 dts files not being supported by the BSDL dtc compiler. You will need 1868 to rebuild your kernel toolchain to pick up the new compiler. Core dumps 1869 may result while building dtb files during a kernel build if you fail 1870 to do so. Set WITHOUT_GPL_DTC if you require the BSDL compiler. 1871 187220140216: 1873 Clang and llvm have been upgraded to 3.4 release. 1874 187520140216: 1876 The nve(4) driver has been removed. Please use the nfe(4) driver 1877 for NVIDIA nForce MCP Ethernet adapters instead. 1878 187920140212: 1880 An ABI incompatibility crept into the libc++ 3.4 import in r261283. 1881 This could cause certain C++ applications using shared libraries built 1882 against the previous version of libc++ to crash. The incompatibility 1883 has now been fixed, but any C++ applications or shared libraries built 1884 between r261283 and r261801 should be recompiled. 1885 188620140204: 1887 OpenSSH will now ignore errors caused by kernel lacking of Capsicum 1888 capability mode support. Please note that enabling the feature in 1889 kernel is still highly recommended. 1890 189120140131: 1892 OpenSSH is now built with sandbox support, and will use sandbox as 1893 the default privilege separation method. This requires Capsicum 1894 capability mode support in kernel. 1895 189620140128: 1897 The libelf and libdwarf libraries have been updated to newer 1898 versions from upstream. Shared library version numbers for 1899 these two libraries were bumped. Any ports or binaries 1900 requiring these two libraries should be recompiled. 1901 __FreeBSD_version is bumped to 1100006. 1902 190320140110: 1904 If a Makefile in a tests/ directory was auto-generating a Kyuafile 1905 instead of providing an explicit one, this would prevent such 1906 Makefile from providing its own Kyuafile in the future during 1907 NO_CLEAN builds. This has been fixed in the Makefiles but manual 1908 intervention is needed to clean an objdir if you use NO_CLEAN: 1909 # find /usr/obj -name Kyuafile | xargs rm -f 1910 191120131213: 1912 The behavior of gss_pseudo_random() for the krb5 mechanism 1913 has changed, for applications requesting a longer random string 1914 than produced by the underlying enctype's pseudo-random() function. 1915 In particular, the random string produced from a session key of 1916 enctype aes256-cts-hmac-sha1-96 or aes256-cts-hmac-sha1-96 will 1917 be different at the 17th octet and later, after this change. 1918 The counter used in the PRF+ construction is now encoded as a 1919 big-endian integer in accordance with RFC 4402. 1920 __FreeBSD_version is bumped to 1100004. 1921 192220131108: 1923 The WITHOUT_ATF build knob has been removed and its functionality 1924 has been subsumed into the more generic WITHOUT_TESTS. If you were 1925 using the former to disable the build of the ATF libraries, you 1926 should change your settings to use the latter. 1927 192820131025: 1929 The default version of mtree is nmtree which is obtained from 1930 NetBSD. The output is generally the same, but may vary 1931 slightly. If you found you need identical output adding 1932 "-F freebsd9" to the command line should do the trick. For the 1933 time being, the old mtree is available as fmtree. 1934 193520131014: 1936 libbsdyml has been renamed to libyaml and moved to /usr/lib/private. 1937 This will break ports-mgmt/pkg. Rebuild the port, or upgrade to pkg 1938 1.1.4_8 and verify bsdyml not linked in, before running "make 1939 delete-old-libs": 1940 # make -C /usr/ports/ports-mgmt/pkg build deinstall install clean 1941 or 1942 # pkg install pkg; ldd /usr/local/sbin/pkg | grep bsdyml 1943 194420131010: 1945 The stable/10 branch has been created in subversion from head 1946 revision r256279. 1947 1948COMMON ITEMS: 1949 1950 General Notes 1951 ------------- 1952 Sometimes, obscure build problems are the result of environment 1953 poisoning. This can happen because the make utility reads its 1954 environment when searching for values for global variables. To run 1955 your build attempts in an "environmental clean room", prefix all make 1956 commands with 'env -i '. See the env(1) manual page for more details. 1957 Occasionally a build failure will occur with "make -j" due to a race 1958 condition. If this happens try building again without -j, and please 1959 report a bug if it happens consistently. 1960 1961 When upgrading from one major version to another it is generally best to 1962 upgrade to the latest code in the currently installed branch first, then 1963 do an upgrade to the new branch. This is the best-tested upgrade path, 1964 and has the highest probability of being successful. Please try this 1965 approach if you encounter problems with a major version upgrade. Since 1966 the stable 4.x branch point, one has generally been able to upgrade from 1967 anywhere in the most recent stable branch to head / current (or even the 1968 last couple of stable branches). See the top of this file when there's 1969 an exception. 1970 1971 When upgrading a live system, having a root shell around before 1972 installing anything can help undo problems. Not having a root shell 1973 around can lead to problems if pam has changed too much from your 1974 starting point to allow continued authentication after the upgrade. 1975 1976 This file should be read as a log of events. When a later event changes 1977 information of a prior event, the prior event should not be deleted. 1978 Instead, a pointer to the entry with the new information should be 1979 placed in the old entry. Readers of this file should also sanity check 1980 older entries before relying on them blindly. Authors of new entries 1981 should write them with this in mind. 1982 1983 ZFS notes 1984 --------- 1985 When upgrading the boot ZFS pool to a new version, always follow 1986 these two steps: 1987 1988 1.) recompile and reinstall the ZFS boot loader and boot block 1989 (this is part of "make buildworld" and "make installworld") 1990 1991 2.) update the ZFS boot block on your boot drive 1992 1993 The following example updates the ZFS boot block on the first 1994 partition (freebsd-boot) of a GPT partitioned drive ada0: 1995 "gpart bootcode -p /boot/gptzfsboot -i 1 ada0" 1996 1997 Non-boot pools do not need these updates. 1998 1999 To build a kernel 2000 ----------------- 2001 If you are updating from a prior version of FreeBSD (even one just 2002 a few days old), you should follow this procedure. It is the most 2003 failsafe as it uses a /usr/obj tree with a fresh mini-buildworld, 2004 2005 make kernel-toolchain 2006 make -DALWAYS_CHECK_MAKE buildkernel KERNCONF=YOUR_KERNEL_HERE 2007 make -DALWAYS_CHECK_MAKE installkernel KERNCONF=YOUR_KERNEL_HERE 2008 2009 To test a kernel once 2010 --------------------- 2011 If you just want to boot a kernel once (because you are not sure 2012 if it works, or if you want to boot a known bad kernel to provide 2013 debugging information) run 2014 make installkernel KERNCONF=YOUR_KERNEL_HERE KODIR=/boot/testkernel 2015 nextboot -k testkernel 2016 2017 To rebuild everything and install it on the current system. 2018 ----------------------------------------------------------- 2019 # Note: sometimes if you are running current you gotta do more than 2020 # is listed here if you are upgrading from a really old current. 2021 2022 <make sure you have good level 0 dumps> 2023 make buildworld 2024 make buildkernel KERNCONF=YOUR_KERNEL_HERE 2025 make installkernel KERNCONF=YOUR_KERNEL_HERE 2026 [1] 2027 <reboot in single user> [3] 2028 mergemaster -Fp [5] 2029 make installworld 2030 mergemaster -Fi [4] 2031 make delete-old [6] 2032 <reboot> 2033 2034 To cross-install current onto a separate partition 2035 -------------------------------------------------- 2036 # In this approach we use a separate partition to hold 2037 # current's root, 'usr', and 'var' directories. A partition 2038 # holding "/", "/usr" and "/var" should be about 2GB in 2039 # size. 2040 2041 <make sure you have good level 0 dumps> 2042 <boot into -stable> 2043 make buildworld 2044 make buildkernel KERNCONF=YOUR_KERNEL_HERE 2045 <maybe newfs current's root partition> 2046 <mount current's root partition on directory ${CURRENT_ROOT}> 2047 make installworld DESTDIR=${CURRENT_ROOT} -DDB_FROM_SRC 2048 make distribution DESTDIR=${CURRENT_ROOT} # if newfs'd 2049 make installkernel KERNCONF=YOUR_KERNEL_HERE DESTDIR=${CURRENT_ROOT} 2050 cp /etc/fstab ${CURRENT_ROOT}/etc/fstab # if newfs'd 2051 <edit ${CURRENT_ROOT}/etc/fstab to mount "/" from the correct partition> 2052 <reboot into current> 2053 <do a "native" rebuild/install as described in the previous section> 2054 <maybe install compatibility libraries from ports/misc/compat*> 2055 <reboot> 2056 2057 2058 To upgrade in-place from stable to current 2059 ---------------------------------------------- 2060 <make sure you have good level 0 dumps> 2061 make buildworld [9] 2062 make buildkernel KERNCONF=YOUR_KERNEL_HERE [8] 2063 make installkernel KERNCONF=YOUR_KERNEL_HERE 2064 [1] 2065 <reboot in single user> [3] 2066 mergemaster -Fp [5] 2067 make installworld 2068 mergemaster -Fi [4] 2069 make delete-old [6] 2070 <reboot> 2071 2072 Make sure that you've read the UPDATING file to understand the 2073 tweaks to various things you need. At this point in the life 2074 cycle of current, things change often and you are on your own 2075 to cope. The defaults can also change, so please read ALL of 2076 the UPDATING entries. 2077 2078 Also, if you are tracking -current, you must be subscribed to 2079 freebsd-current@freebsd.org. Make sure that before you update 2080 your sources that you have read and understood all the recent 2081 messages there. If in doubt, please track -stable which has 2082 much fewer pitfalls. 2083 2084 [1] If you have third party modules, such as vmware, you 2085 should disable them at this point so they don't crash your 2086 system on reboot. 2087 2088 [3] From the bootblocks, boot -s, and then do 2089 fsck -p 2090 mount -u / 2091 mount -a 2092 sh /etc/rc.d/zfs start # mount zfs filesystem, if needed 2093 cd src # full path to source 2094 adjkerntz -i # if CMOS is wall time 2095 Also, when doing a major release upgrade, it is required that 2096 you boot into single user mode to do the installworld. 2097 2098 [4] Note: This step is non-optional. Failure to do this step 2099 can result in a significant reduction in the functionality of the 2100 system. Attempting to do it by hand is not recommended and those 2101 that pursue this avenue should read this file carefully, as well 2102 as the archives of freebsd-current and freebsd-hackers mailing lists 2103 for potential gotchas. The -U option is also useful to consider. 2104 See mergemaster(8) for more information. 2105 2106 [5] Usually this step is a no-op. However, from time to time 2107 you may need to do this if you get unknown user in the following 2108 step. It never hurts to do it all the time. You may need to 2109 install a new mergemaster (cd src/usr.sbin/mergemaster && make 2110 install) after the buildworld before this step if you last updated 2111 from current before 20130425 or from -stable before 20130430. 2112 2113 [6] This only deletes old files and directories. Old libraries 2114 can be deleted by "make delete-old-libs", but you have to make 2115 sure that no program is using those libraries anymore. 2116 2117 [8] The new kernel must be able to run existing binaries used by an 2118 installworld. When upgrading across major versions, the new kernel's 2119 configuration must include the correct COMPAT_FREEBSD<n> option for 2120 existing binaries (e.g. COMPAT_FREEBSD11 to run 11.x binaries). Failure 2121 to do so may leave you with a system that is hard to boot to recover. A 2122 GENERIC kernel will include suitable compatibility options to run 2123 binaries from older branches. Note that the ability to run binaries 2124 from unsupported branches is not guaranteed. 2125 2126 Make sure that you merge any new devices from GENERIC since the 2127 last time you updated your kernel config file. Options also 2128 change over time, so you may need to adjust your custom kernels 2129 for these as well. 2130 2131 [9] If CPUTYPE is defined in your /etc/make.conf, make sure to use the 2132 "?=" instead of the "=" assignment operator, so that buildworld can 2133 override the CPUTYPE if it needs to. 2134 2135 MAKEOBJDIRPREFIX must be defined in an environment variable, and 2136 not on the command line, or in /etc/make.conf. buildworld will 2137 warn if it is improperly defined. 2138FORMAT: 2139 2140This file contains a list, in reverse chronological order, of major 2141breakages in tracking -current. It is not guaranteed to be a complete 2142list of such breakages, and only contains entries since September 23, 2011. 2143If you need to see UPDATING entries from before that date, you will need 2144to fetch an UPDATING file from an older FreeBSD release. 2145 2146Copyright information: 2147 2148Copyright 1998-2009 M.
