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 2920191003: 30 The hpt27xx, hptmv, hptnr, and hptrr drivers have been removed from 31 GENERIC. They are available as modules and can be loaded by adding 32 to /boot/loader.conf hpt27xx_load="YES", hptmv_load="YES", 33 hptnr_load="YES", or hptrr_load="YES", respectively. 34 3520190913: 36 ntpd no longer by default locks its pages in memory, allowing them 37 to be paged out by the kernel. Use rlimit memlock to restore 38 historic BSD behaviour. For example, add "rlimit memlock 32" 39 to ntp.conf to lock up to 32 MB of ntpd address space in memory. 40 4120190823: 42 Several of ping6's options have been renamed for better consistency 43 with ping. If you use any of -ARWXaghmrtwx, you must update your 44 scripts. See ping6(8) for details. 45 4620190727: 47 The vfs.fusefs.sync_unmount and vfs.fusefs.init_backgrounded sysctls 48 and the "-o sync_unmount" and "-o init_backgrounded" mount options have 49 been removed from mount_fusefs(8). You can safely remove them from 50 your scripts, because they had no effect. 51 52 The vfs.fusefs.fix_broken_io, vfs.fusefs.sync_resize, 53 vfs.fusefs.refresh_size, vfs.fusefs.mmap_enable, 54 vfs.fusefs.reclaim_revoked, and vfs.fusefs.data_cache_invalidate 55 sysctls have been removed. If you felt the need to set any of them to 56 a non-default value, please tell asomers@FreeBSD.org why. 57 5820190713: 59 Default permissions on the /var/account/acct file (and copies of it 60 rotated by periodic daily scripts) are changed from 0644 to 0640 61 because the file contains sensitive information that should not be 62 world-readable. If the /var/account directory must be created by 63 rc.d/accounting, the mode used is now 0750. Admins who use the 64 accounting feature are encouraged to change the mode of an existing 65 /var/account directory to 0750 or 0700. 66 6720190620: 68 Entropy collection and the /dev/random device are no longer optional 69 components. The "device random" option has been removed. 70 Implementations of distilling algorithms can still be made loadable 71 with "options RANDOM_LOADABLE" (e.g., random_fortuna.ko). 72 7320190612: 74 Clang, llvm, lld, lldb, compiler-rt, libc++, libunwind and openmp have 75 been upgraded to 8.0.1. Please see the 20141231 entry below for 76 information about prerequisites and upgrading, if you are not already 77 using clang 3.5.0 or higher. 78 7920190608: 80 A fix was applied to i386 kernel modules to avoid panics with 81 dpcpu or vnet. Users need to recompile i386 kernel modules 82 having pcpu or vnet sections or they will refuse to load. 83 8420190513: 85 User-wired pages now have their own counter, 86 vm.stats.vm.v_user_wire_count. The vm.max_wired sysctl was renamed 87 to vm.max_user_wired and changed from an unsigned int to an unsigned 88 long. bhyve VMs wired with the -S are now subject to the user 89 wiring limit; the vm.max_user_wired sysctl may need to be tuned to 90 avoid running into the limit. 91 9220190507: 93 The IPSEC option has been removed from GENERIC. Users requiring 94 ipsec(4) must now load the ipsec(4) kernel module. 95 9620190507: 97 The tap(4) driver has been folded into tun(4), and the module has been 98 renamed to tuntap. You should update any kld_list="if_tap" or 99 kld_list="if_tun" entries in /etc/rc.conf, if_tap_load="YES" or 100 if_tun_load="YES" entries in /boot/loader.conf to load the if_tuntap 101 module instead, and "device tap" or "device tun" entries in kernel 102 config files to select the tuntap device instead. 103 10420190418: 105 The following knobs have been added related to tradeoffs between 106 safe use of the random device and availability in the absence of 107 entropy: 108 109 kern.random.initial_seeding.bypass_before_seeding: tunable; set 110 non-zero to bypass the random device prior to seeding, or zero to 111 block random requests until the random device is initially seeded. 112 For now, set to 1 (unsafe) by default to restore pre-r346250 boot 113 availability properties. 114 115 kern.random.initial_seeding.read_random_bypassed_before_seeding: 116 read-only diagnostic sysctl that is set when bypass is enabled and 117 read_random(9) is bypassed, to enable programmatic handling of this 118 initial condition, if desired. 119 120 kern.random.initial_seeding.arc4random_bypassed_before_seeding: 121 Similar to the above, but for for arc4random(9) initial seeding. 122 123 kern.random.initial_seeding.disable_bypass_warnings: tunable; set 124 non-zero to disable warnings in dmesg when the same conditions are 125 met as for the diagnostic sysctls above. Defaults to zero, i.e., 126 produce warnings in dmesg when the conditions are met. 127 12820190416: 129 The loadable random module KPI has changed; the random_infra_init() 130 routine now requires a 3rd function pointer for a bool (*)(void) 131 method that returns true if the random device is seeded (and 132 therefore unblocked). 133 13420190404: 135 r345895 reverts r320698. This implies that an nfsuserd(8) daemon 136 built from head sources between r320757 (July 6, 2017) and 137 r338192 (Aug. 22, 2018) will not work unless the "-use-udpsock" 138 is added to the command line. 139 nfsuserd daemons built from head sources that are post-r338192 are 140 not affected and should continue to work. 141 14220190320: 143 The fuse(4) module has been renamed to fusefs(4) for consistency with 144 other filesystems. You should update any kld_load="fuse" entries in 145 /etc/rc.conf, fuse_load="YES" entries in /boot/loader.conf, and 146 "options FUSE" entries in kernel config files. 147 14820190304: 149 Clang, llvm, lld, lldb, compiler-rt and libc++ have been upgraded to 150 8.0.0. Please see the 20141231 entry below for information about 151 prerequisites and upgrading, if you are not already using clang 3.5.0 152 or higher. 153 15420190226: 155 geom_uzip(4) depends on the new module xz. If geom_uzip is statically 156 compiled into your custom kernel, add 'device xz' statement to the 157 kernel config. 158 15920190219: 160 drm and drm2 have been removed from the tree. Please see 161 https://wiki.freebsd.org/Graphics for the latest information on 162 migrating to the drm ports. 163 16420190131: 165 Iflib is no longer unconditionally compiled into the kernel. Drivers 166 using iflib and statically compiled into the kernel, now require 167 the 'device iflib' config option. For the same drivers loaded as 168 modules on kernels not having 'device iflib', the iflib.ko module 169 is loaded automatically. 170 17120190125: 172 The IEEE80211_AMPDU_AGE and AH_SUPPORT_AR5416 kernel configuration 173 options no longer exist since r343219 and r343427 respectively; 174 nothing uses them, so they should be just removed from custom 175 kernel config files. 176 17720181230: 178 r342635 changes the way efibootmgr(8) works by requiring users to add 179 the -b (bootnum) parameter for commands where the bootnum was previously 180 specified with each option. For example 'efibootmgr -B 0001' is now 181 'efibootmgr -B -b 0001'. 182 18320181220: 184 r342286 modifies the NFSv4 server so that it obeys vfs.nfsd.nfs_privport 185 in the same as it is applied to NFSv2 and 3. This implies that NFSv4 186 servers that have vfs.nfsd.nfs_privport set will only allow mounts 187 from clients using a reserved port#. Since both the FreeBSD and Linux 188 NFSv4 clients use reserved port#s by default, this should not affect 189 most NFSv4 mounts. 190 19120181219: 192 The XLP config has been removed. We can't support 64-bit atomics in this 193 kernel because it is running in 32-bit mode. XLP users must transition 194 to running a 64-bit kernel (XLP64 or XLPN32). 195 196 The mips GXEMUL support has been removed from FreeBSD. MALTA* + qemu is 197 the preferred emulator today and we don't need two different ones. 198 199 The old sibyte / swarm / Broadcom BCM1250 support has been 200 removed from the mips port. 201 20220181211: 203 Clang, llvm, lld, lldb, compiler-rt and libc++ have been upgraded to 204 7.0.1. Please see the 20141231 entry below for information about 205 prerequisites and upgrading, if you are not already using clang 3.5.0 206 or higher. 207 20820181211: 209 Remove the timed and netdate programs from the base tree. Setting 210 the time with these daemons has been obsolete for over a decade. 211 21220181126: 213 On amd64, arm64 and armv7 (architectures that install LLVM's ld.lld 214 linker as /usr/bin/ld) GNU ld is no longer installed as ld.bfd, as 215 it produces broken binaries when ifuncs are in use. Users needing 216 GNU ld should install the binutils port or package. 217 21820181123: 219 The BSD crtbegin and crtend code has been enabled by default. It has 220 had extensive testing on amd64, arm64, and i386. It can be disabled 221 by building a world with -DWITHOUT_BSD_CRTBEGIN. 222 22320181115: 224 The set of CTM commands (ctm, ctm_smail, ctm_rmail, ctm_dequeue) 225 has been converted to a port (misc/ctm) and will be removed from 226 FreeBSD-13. It is available as a package (ctm) for all supported 227 FreeBSD versions. 228 22920181110: 230 The default newsyslog.conf(5) file has been changed to only include 231 files in /etc/newsyslog.conf.d/ and /usr/local/etc/newsyslog.conf.d/ if 232 the filenames end in '.conf' and do not begin with a '.'. 233 234 You should check the configuration files in these two directories match 235 this naming convention. You can verify which configuration files are 236 being included using the command: 237 $ newsyslog -Nrv 238 23920181015: 240 Ports for the DRM modules have been simplified. Now, amd64 users should 241 just install the drm-kmod port. All others should install 242 drm-legacy-kmod. 243 244 Graphics hardware that's newer than about 2010 usually works with 245 drm-kmod. For hardware older than 2013, however, some users will need 246 to use drm-legacy-kmod if drm-kmod doesn't work for them. Hardware older 247 than 2008 usually only works in drm-legacy-kmod. The graphics team can 248 only commit to hardware made since 2013 due to the complexity of the 249 market and difficulty to test all the older cards effectively. If you 250 have hardware supported by drm-kmod, you are strongly encouraged to use 251 that as you will get better support. 252 253 Other than KPI chasing, drm-legacy-kmod will not be updated. As outlined 254 elsewhere, the drm and drm2 modules will be eliminated from the src base 255 soon (with a limited exception for arm). Please update to the package 256 asap and report any issues to x11@freebsd.org. 257 258 Generally, anybody using the drm*-kmod packages should add 259 WITHOUT_DRM_MODULE=t and WITHOUT_DRM2_MODULE=t to avoid nasty 260 cross-threading surprises, especially with automatic driver 261 loading from X11 startup. These will become the defaults in 13-current 262 shortly. 263 26420181012: 265 The ixlv(4) driver has been renamed to iavf(4). As a consequence, 266 custom kernel and module loading configuration files must be updated 267 accordingly. Moreover, interfaces previous presented as ixlvN to the 268 system are now exposed as iavfN and network configuration files must 269 be adjusted as necessary. 270 27120181009: 272 OpenSSL has been updated to version 1.1.1. This update included 273 additional various API changes throughout the base system. It is 274 important to rebuild third-party software after upgrading. The value 275 of __FreeBSD_version has been bumped accordingly. 276 27720181006: 278 The legacy DRM modules and drivers have now been added to the loader's 279 module blacklist, in favor of loading them with kld_list in rc.conf(5). 280 The module blacklist may be overridden with the loader.conf(5) 281 'module_blacklist' variable, but loading them via rc.conf(5) is strongly 282 encouraged. 283 28420181002: 285 The cam(4) based nda(4) driver will be used over nvd(4) by default on 286 powerpc64. You may set 'options NVME_USE_NVD=1' in your kernel conf or 287 loader tunable 'hw.nvme.use_nvd=1' if you wish to use the existing 288 driver. Make sure to edit /boot/etc/kboot.conf and fstab to use the 289 nda device name. 290 29120180913: 292 Reproducible build mode is now on by default, in preparation for 293 FreeBSD 12.0. This eliminates build metadata such as the user, 294 host, and time from the kernel (and uname), unless the working tree 295 corresponds to a modified checkout from a version control system. 296 The previous behavior can be obtained by setting the /etc/src.conf 297 knob WITHOUT_REPRODUCIBLE_BUILD. 298 29920180826: 300 The Yarrow CSPRNG has been removed from the kernel as it has not been 301 supported by its designers since at least 2003. Fortuna has been the 302 default since FreeBSD-11. 303 30420180822: 305 devctl freeze/thaw have gone into the tree, the rc scripts have been 306 updated to use them and devmatch has been changed. You should update 307 kernel, userland and rc scripts all at the same time. 308 30920180818: 310 The default interpreter has been switched from 4th to Lua. 311 LOADER_DEFAULT_INTERP, documented in build(7), will override the default 312 interpreter. If you have custom FORTH code you will need to set 313 LOADER_DEFAULT_INTERP=4th (valid values are 4th, lua or simp) in 314 src.conf for the build. This will create default hard links between 315 loader and loader_4th instead of loader and loader_lua, the new default. 316 If you are using UEFI it will create the proper hard link to loader.efi. 317 318 bhyve uses userboot.so. It remains 4th-only until some issues are solved 319 regarding coexisting with multiple versions of FreeBSD are resolved. 320 32120180815: 322 ls(1) now respects the COLORTERM environment variable used in other 323 systems and software to indicate that a colored terminal is both 324 supported and desired. If ls(1) is suddenly emitting colors, they may 325 be disabled again by either removing the unwanted COLORTERM from your 326 environment, or using `ls --color=never`. The ls(1) specific CLICOLOR 327 may not be observed in a future release. 328 32920180808: 330 The default pager for most commands has been changed to "less". To 331 restore the old behavior, set PAGER="more" and MANPAGER="more -s" in 332 your environment. 333 33420180731: 335 The jedec_ts(4) driver has been removed. A superset of its functionality 336 is available in the jedec_dimm(4) driver, and the manpage for that 337 driver includes migration instructions. If you have "device jedec_ts" 338 in your kernel configuration file, it must be removed. 339 34020180730: 341 amd64/GENERIC now has EFI runtime services, EFIRT, enabled by default. 342 This should have no effect if the kernel is booted via BIOS/legacy boot. 343 EFIRT may be disabled via a loader tunable, efi.rt.disabled, if a system 344 has a buggy firmware that prevents a successful boot due to use of 345 runtime services. 346 34720180727: 348 Atmel AT91RM9200 and AT91SAM9, Cavium CNS 11xx and XScale 349 support has been removed from the tree. These ports were 350 obsolete and/or known to be broken for many years. 351 35220180723: 353 loader.efi has been augmented to participate more fully in the 354 UEFI boot manager protocol. loader.efi will now look at the 355 BootXXXX environment variable to determine if a specific kernel 356 or root partition was specified. XXXX is derived from BootCurrent. 357 efibootmgr(8) manages these standard UEFI variables. 358 35920180720: 360 zfsloader's functionality has now been folded into loader. 361 zfsloader is no longer necessary once you've updated your 362 boot blocks. For a transition period, we will install a 363 hardlink for zfsloader to loader to allow a smooth transition 364 until the boot blocks can be updated (hard link because old 365 zfs boot blocks don't understand symlinks). 366 36720180719: 368 ARM64 now have efifb support, if you want to have serial console 369 on your arm64 board when an screen is connected and the bootloader 370 setup a frame buffer for us to use, just add : 371 boot_serial=YES 372 boot_multicons=YES 373 in /boot/loader.conf 374 For Raspberry Pi 3 (RPI) users, this is needed even if you don't have 375 an screen connected as the firmware will setup a frame buffer are that 376 u-boot will expose as an EFI frame buffer. 377 37820180719: 379 New uid:gid added, ntpd:ntpd (123:123). Be sure to run mergemaster 380 or take steps to update /etc/passwd before doing installworld on 381 existing systems. Do not skip the "mergemaster -Fp" step before 382 installworld, as described in the update procedures near the bottom 383 of this document. Also, rc.d/ntpd now starts ntpd(8) as user ntpd 384 if the new mac_ntpd(4) policy is available, unless ntpd_flags or 385 the ntp config file contain options that change file/dir locations. 386 When such options (e.g., "statsdir" or "crypto") are used, ntpd can 387 still be run as non-root by setting ntpd_user=ntpd in rc.conf, after 388 taking steps to ensure that all required files/dirs are accessible 389 by the ntpd user. 390 39120180717: 392 Big endian arm support has been removed. 393 39420180711: 395 The static environment setup in kernel configs is no longer mutually 396 exclusive with the loader(8) environment by default. In order to 397 restore the previous default behavior of disabling the loader(8) 398 environment if a static environment is present, you must specify 399 loader_env.disabled=1 in the static environment. 400 40120180705: 402 The ABI of syscalls used by management tools like sockstat and 403 netstat has been broken to allow 32-bit binaries to work on 404 64-bit kernels without modification. These programs will need 405 to match the kernel in order to function. External programs may 406 require minor modifications to accommodate a change of type in 407 structures from pointers to 64-bit virtual addresses. 408 40920180702: 410 On i386 and amd64 atomics are now inlined. Out of tree modules using 411 atomics will need to be rebuilt. 412 41320180701: 414 The '%I' format in the kern.corefile sysctl limits the number of 415 core files that a process can generate to the number stored in the 416 debug.ncores sysctl. The '%I' format is replaced by the single digit 417 index. Previously, if all indexes were taken the kernel would overwrite 418 only a core file with the highest index in a filename. 419 Currently the system will create a new core file if there is a free 420 index or if all slots are taken it will overwrite the oldest one. 421 42220180630: 423 Clang, llvm, lld, lldb, compiler-rt and libc++ have been upgraded to 424 6.0.1. Please see the 20141231 entry below for information about 425 prerequisites and upgrading, if you are not already using clang 3.5.0 426 or higher. 427 42820180628: 429 r335753 introduced a new quoting method. However, etc/devd/devmatch.conf 430 needed to be changed to work with it. This change was made with r335763 431 and requires a mergemaster / etcupdate / etc to update the installed 432 file. 433 43420180612: 435 r334930 changed the interface between the NFS modules, so they all 436 need to be rebuilt. r335018 did a __FreeBSD_version bump for this. 437 43820180530: 439 As of r334391 lld is the default amd64 system linker; it is installed 440 as /usr/bin/ld. Kernel build workarounds (see 20180510 entry) are no 441 longer necessary. 442 44320180530: 444 The kernel / userland interface for devinfo changed, so you'll 445 need a new kernel and userland as a pair for it to work (rebuilding 446 lib/libdevinfo is all that's required). devinfo and devmatch will 447 not work, but everything else will when there's a mismatch. 448 44920180523: 450 The on-disk format for hwpmc callchain records has changed to include 451 threadid corresponding to a given record. This changes the field offsets 452 and thus requires that libpmcstat be rebuilt before using a kernel 453 later than r334108. 454 45520180517: 456 The vxge(4) driver has been removed. This driver was introduced into 457 HEAD one week before the Exar left the Ethernet market and is not 458 known to be used. If you have device vxge in your kernel config file 459 it must be removed. 460 46120180510: 462 The amd64 kernel now requires a ld that supports ifunc to produce a 463 working kernel, either lld or a newer binutils. lld is built by default 464 on amd64, and the 'buildkernel' target uses it automatically. However, 465 it is not the default linker, so building the kernel the traditional 466 way requires LD=ld.lld on the command line (or LD=/usr/local/bin/ld for 467 binutils port/package). lld will soon be default, and this requirement 468 will go away. 469 470 NOTE: As of r334391 lld is the default system linker on amd64, and no 471 workaround is necessary. 472 47320180508: 474 The nxge(4) driver has been removed. This driver was for PCI-X 10g 475 cards made by s2io/Neterion. The company was acquired by Exar and 476 no longer sells or supports Ethernet products. If you have device 477 nxge in your kernel config file it must be removed. 478 47920180504: 480 The tz database (tzdb) has been updated to 2018e. This version more 481 correctly models time stamps in time zones with negative DST such as 482 Europe/Dublin (from 1971 on), Europe/Prague (1946/7), and 483 Africa/Windhoek (1994/2017). This does not affect the UT offsets, only 484 time zone abbreviations and the tm_isdst flag. 485 48620180502: 487 The ixgb(4) driver has been removed. This driver was for an early and 488 uncommon legacy PCI 10GbE for a single ASIC, Intel 82597EX. Intel 489 quickly shifted to the long lived ixgbe family. If you have device 490 ixgb in your kernel config file it must be removed. 491 49220180501: 493 The lmc(4) driver has been removed. This was a WAN interface 494 card that was already reportedly rare in 2003, and had an ambiguous 495 license. If you have device lmc in your kernel config file it must 496 be removed. 497 49820180413: 499 Support for Arcnet networks has been removed. If you have device 500 arcnet or device cm in your kernel config file they must be 501 removed. 502 50320180411: 504 Support for FDDI networks has been removed. If you have device 505 fddi or device fpa in your kernel config file they must be 506 removed. 507 50820180406: 509 In addition to supporting RFC 3164 formatted messages, the 510 syslogd(8) service is now capable of parsing RFC 5424 formatted 511 log messages. The main benefit of using RFC 5424 is that clients 512 may now send log messages with timestamps containing year numbers, 513 microseconds and time zone offsets. 514 515 Similarly, the syslog(3) C library function has been altered to 516 send RFC 5424 formatted messages to the local system logging 517 daemon. On systems using syslogd(8), this change should have no 518 negative impact, as long as syslogd(8) and the C library are 519 updated at the same time. On systems using a different system 520 logging daemon, it may be necessary to make configuration 521 adjustments, depending on the software used. 522 523 When using syslog-ng, add the 'syslog-protocol' flag to local 524 input sources to enable parsing of RFC 5424 formatted messages: 525 526 source src { 527 unix-dgram("/var/run/log" flags(syslog-protocol)); 528 } 529 530 When using rsyslog, disable the 'SysSock.UseSpecialParser' option 531 of the 'imuxsock' module to let messages be processed by the 532 regular RFC 3164/5424 parsing pipeline: 533 534 module(load="imuxsock" SysSock.UseSpecialParser="off") 535 536 Do note that these changes only affect communication between local 537 applications and syslogd(8). The format that syslogd(8) uses to 538 store messages on disk or forward messages to other systems 539 remains unchanged. syslogd(8) still uses RFC 3164 for these 540 purposes. Options to customize this behaviour will be added in the 541 future. Utilities that process log files stored in /var/log are 542 thus expected to continue to function as before. 543 544 __FreeBSD_version has been incremented to 1200061 to denote this 545 change. 546 54720180328: 548 Support for token ring networks has been removed. If you 549 have "device token" in your kernel config you should remove 550 it. No device drivers supported token ring. 551 55220180323: 553 makefs was modified to be able to tag ISO9660 El Torito boot catalog 554 entries as EFI instead of overloading the i386 tag as done previously. 555 The amd64 mkisoimages.sh script used to build amd64 ISO images for 556 release was updated to use this. This may mean that makefs must be 557 updated before "make cdrom" can be run in the release directory. This 558 should be as simple as: 559 560 $ cd $SRCDIR/usr.sbin/makefs 561 $ make depend all install 562 56320180212: 564 FreeBSD boot loader enhanced with Lua scripting. It's purely opt-in for 565 now by building WITH_LOADER_LUA and WITHOUT_FORTH in /etc/src.conf. 566 Co-existence for the transition period will come shortly. Booting is a 567 complex environment and test coverage for Lua-enabled loaders has been 568 thin, so it would be prudent to assume it might not work and make 569 provisions for backup boot methods. 570 57120180211: 572 devmatch functionality has been turned on in devd. It will automatically 573 load drivers for unattached devices. This may cause unexpected drivers 574 to be loaded. Please report any problems to current@ and 575 imp@freebsd.org. 576 57720180114: 578 Clang, llvm, lld, lldb, compiler-rt and libc++ have been upgraded to 579 6.0.0. Please see the 20141231 entry below for information about 580 prerequisites and upgrading, if you are not already using clang 3.5.0 581 or higher. 582 58320180110: 584 LLVM's lld linker is now used as the FreeBSD/amd64 bootstrap linker. 585 This means it is used to link the kernel and userland libraries and 586 executables, but is not yet installed as /usr/bin/ld by default. 587 588 To revert to ld.bfd as the bootstrap linker, in /etc/src.conf set 589 WITHOUT_LLD_BOOTSTRAP=yes 590 59120180110: 592 On i386, pmtimer has been removed. Its functionality has been folded 593 into apm. It was a no-op on ACPI in current for a while now (but was 594 still needed on i386 in FreeBSD 11 and earlier). Users may need to 595 remove it from kernel config files. 596 59720180104: 598 The use of RSS hash from the network card aka flowid has been 599 disabled by default for lagg(4) as it's currently incompatible with 600 the lacp and loadbalance protocols. 601 602 This can be re-enabled by setting the following in loader.conf: 603 net.link.lagg.default_use_flowid="1" 604 60520180102: 606 The SW_WATCHDOG option is no longer necessary to enable the 607 hardclock-based software watchdog if no hardware watchdog is 608 configured. As before, SW_WATCHDOG will cause the software 609 watchdog to be enabled even if a hardware watchdog is configured. 610 61120171215: 612 r326887 fixes the issue described in the 20171214 UPDATING entry. 613 r326888 flips the switch back to building GELI support always. 614 61520171214: 616 r362593 broke ZFS + GELI support for reasons unknown. However, 617 it also broke ZFS support generally, so GELI has been turned off 618 by default as the lesser evil in r326857. If you boot off ZFS and/or 619 GELI, it might not be a good time to update. 620 62120171125: 622 PowerPC users must update loader(8) by rebuilding world before 623 installing a new kernel, as the protocol connecting them has 624 changed. Without the update, loader metadata will not be passed 625 successfully to the kernel and users will have to enter their 626 root partition at the kernel mountroot prompt to continue booting. 627 Newer versions of loader can boot old kernels without issue. 628 62920171110: 630 The LOADER_FIREWIRE_SUPPORT build variable as been renamed to 631 WITH/OUT_LOADER_FIREWIRE. LOADER_{NO_,}GELI_SUPPORT has been renamed 632 to WITH/OUT_LOADER_GELI. 633 63420171106: 635 The naive and non-compliant support of posix_fallocate(2) in ZFS 636 has been removed as of r325320. The system call now returns EINVAL 637 when used on a ZFS file. Although the new behavior complies with the 638 standard, some consumers are not prepared to cope with it. 639 One known victim is lld prior to r325420. 640 64120171102: 642 Building in a FreeBSD src checkout will automatically create object 643 directories now rather than store files in the current directory if 644 'make obj' was not ran. Calling 'make obj' is no longer necessary. 645 This feature can be disabled by setting WITHOUT_AUTO_OBJ=yes in 646 /etc/src-env.conf (not /etc/src.conf), or passing the option in the 647 environment. 648 64920171101: 650 The default MAKEOBJDIR has changed from /usr/obj/<srcdir> for native 651 builds, and /usr/obj/<arch>/<srcdir> for cross-builds, to a unified 652 /usr/obj/<srcdir>/<arch>. This behavior can be changed to the old 653 format by setting WITHOUT_UNIFIED_OBJDIR=yes in /etc/src-env.conf, 654 the environment, or with -DWITHOUT_UNIFIED_OBJDIR when building. 655 The UNIFIED_OBJDIR option is a transitional feature that will be 656 removed for 12.0 release; please migrate to the new format for any 657 tools by looking up the OBJDIR used by 'make -V .OBJDIR' means rather 658 than hardcoding paths. 659 66020171028: 661 The native-xtools target no longer installs the files by default to the 662 OBJDIR. Use the native-xtools-install target with a DESTDIR to install 663 to ${DESTDIR}/${NXTP} where NXTP defaults to /nxb-bin. 664 66520171021: 666 As part of the boot loader infrastructure cleanup, LOADER_*_SUPPORT 667 options are changing from controlling the build if defined / undefined 668 to controlling the build with explicit 'yes' or 'no' values. They will 669 shift to WITH/WITHOUT options to match other options in the system. 670 67120171010: 672 libstand has turned into a private library for sys/boot use only. 673 It is no longer supported as a public interface outside of sys/boot. 674 67520171005: 676 The arm port has split armv6 into armv6 and armv7. armv7 is now 677 a valid TARGET_ARCH/MACHINE_ARCH setting. If you have an armv7 system 678 and are running a kernel from before r324363, you will need to add 679 MACHINE_ARCH=armv7 to 'make buildworld' to do a native build. 680 68120171003: 682 When building multiple kernels using KERNCONF, non-existent KERNCONF 683 files will produce an error and buildkernel will fail. Previously 684 missing KERNCONF files silently failed giving no indication as to 685 why, only to subsequently discover during installkernel that the 686 desired kernel was never built in the first place. 687 68820170912: 689 The default serial number format for CTL LUNs has changed. This will 690 affect users who use /dev/diskid/* device nodes, or whose FibreChannel 691 or iSCSI clients care about their LUNs' serial numbers. Users who 692 require serial number stability should hardcode serial numbers in 693 /etc/ctl.conf . 694 69520170912: 696 For 32-bit arm compiled for hard-float support, soft-floating point 697 binaries now always get their shared libraries from 698 LD_SOFT_LIBRARY_PATH (in the past, this was only used if 699 /usr/libsoft also existed). Only users with a hard-float ld.so, but 700 soft-float everything else should be affected. 701 70220170826: 703 The geli password typed at boot is now hidden. To restore the previous 704 behavior, see geli(8) for configuration options. 705 70620170825: 707 Move PMTUD blackhole counters to TCPSTATS and remove them from bare 708 sysctl values. Minor nit, but requires a rebuild of both world/kernel 709 to complete. 710 71120170814: 712 "make check" behavior (made in ^/head@r295380) has been changed to 713 execute from a limited sandbox, as opposed to executing from 714 ${TESTSDIR}. 715 716 Behavioral changes: 717 - The "beforecheck" and "aftercheck" targets are now specified. 718 - ${CHECKDIR} (added in commit noted above) has been removed. 719 - Legacy behavior can be enabled by setting 720 WITHOUT_MAKE_CHECK_USE_SANDBOX in src.conf(5) or the environment. 721 722 If the limited sandbox mode is enabled, "make check" will execute 723 "make distribution", then install, execute the tests, and clean up the 724 sandbox if successful. 725 726 The "make distribution" and "make install" targets are typically run as 727 root to set appropriate permissions and ownership at installation time. 728 The end-user should set "WITH_INSTALL_AS_USER" in src.conf(5) or the 729 environment if executing "make check" with limited sandbox mode using 730 an unprivileged user. 731 73220170808: 733 Since the switch to GPT disk labels, fsck for UFS/FFS has been 734 unable to automatically find alternate superblocks. As of r322297, 735 the information needed to find alternate superblocks has been 736 moved to the end of the area reserved for the boot block. 737 Filesystems created with a newfs of this vintage or later 738 will create the recovery information. If you have a filesystem 739 created prior to this change and wish to have a recovery block 740 created for your filesystem, you can do so by running fsck in 741 foreground mode (i.e., do not use the -p or -y options). As it 742 starts, fsck will ask ``SAVE DATA TO FIND ALTERNATE SUPERBLOCKS'' 743 to which you should answer yes. 744 74520170728: 746 As of r321665, an NFSv4 server configuration that services 747 Kerberos mounts or clients that do not support the uid/gid in 748 owner/owner_group string capability, must explicitly enable 749 the nfsuserd daemon by adding nfsuserd_enable="YES" to the 750 machine's /etc/rc.conf file. 751 75220170722: 753 Clang, llvm, lldb, compiler-rt and libc++ have been upgraded to 5.0.0. 754 Please see the 20141231 entry below for information about prerequisites 755 and upgrading, if you are not already using clang 3.5.0 or higher. 756 75720170701: 758 WITHOUT_RCMDS is now the default. Set WITH_RCMDS if you need the 759 r-commands (rlogin, rsh, etc.) to be built with the base system. 760 76120170625: 762 The FreeBSD/powerpc platform now uses a 64-bit type for time_t. This is 763 a very major ABI incompatible change, so users of FreeBSD/powerpc must 764 be careful when performing source upgrades. It is best to run 765 'make installworld' from an alternate root system, either a live 766 CD/memory stick, or a temporary root partition. Additionally, all ports 767 must be recompiled. powerpc64 is largely unaffected, except in the case 768 of 32-bit compatibility. All 32-bit binaries will be affected. 769 77020170623: 771 Forward compatibility for the "ino64" project have been committed. This 772 will allow most new binaries to run on older kernels in a limited 773 fashion. This prevents many of the common foot-shooting actions in the 774 upgrade as well as the limited ability to roll back the kernel across 775 the ino64 upgrade. Complicated use cases may not work properly, though 776 enough simpler ones work to allow recovery in most situations. 777 77820170620: 779 Switch back to the BSDL dtc (Device Tree Compiler). Set WITH_GPL_DTC 780 if you require the GPL compiler. 781 78220170618: 783 The internal ABI used for communication between the NFS kernel modules 784 was changed by r320085, so __FreeBSD_version was bumped to 785 ensure all the NFS related modules are updated together. 786 78720170617: 788 The ABI of struct event was changed by extending the data 789 member to 64bit and adding ext fields. For upgrade, same 790 precautions as for the entry 20170523 "ino64" must be 791 followed. 792 79320170531: 794 The GNU roff toolchain has been removed from base. To render manpages 795 which are not supported by mandoc(1), man(1) can fallback on GNU roff 796 from ports (and recommends to install it). 797 To render roff(7) documents, consider using GNU roff from ports or the 798 heirloom doctools roff toolchain from ports via pkg install groff or 799 via pkg install heirloom-doctools. 800 80120170524: 802 The ath(4) and ath_hal(4) modules now build piecemeal to allow for 803 smaller runtime footprint builds. This is useful for embedded systems 804 which only require one chipset support. 805 806 If you load it as a module, make sure this is in /boot/loader.conf: 807 808 if_ath_load="YES" 809 810 This will load the HAL, all chip/RF backends and if_ath_pci. 811 If you have if_ath_pci in /boot/loader.conf, ensure it is after 812 if_ath or it will not load any HAL chipset support. 813 814 If you want to selectively load things (eg on ye cheape ARM/MIPS 815 platforms where RAM is at a premium) you should: 816 817 * load ath_hal 818 * load the chip modules in question 819 * load ath_rate, ath_dfs 820 * load ath_main 821 * load if_ath_pci and/or if_ath_ahb depending upon your particular 822 bus bind type - this is where probe/attach is done. 823 824 For further comments/feedback, poke adrian@ . 825 82620170523: 827 The "ino64" 64-bit inode project has been committed, which extends 828 a number of types to 64 bits. Upgrading in place requires care and 829 adherence to the documented upgrade procedure. 830 831 If using a custom kernel configuration ensure that the 832 COMPAT_FREEBSD11 option is included (as during the upgrade the 833 system will be running the ino64 kernel with the existing world). 834 835 For the safest in-place upgrade begin by removing previous build 836 artifacts via "rm -rf /usr/obj/*". Then, carefully follow the full 837 procedure documented below under the heading "To rebuild everything and 838 install it on the current system." Specifically, a reboot is required 839 after installing the new kernel before installing world. While an 840 installworld normally works by accident from multiuser after rebooting 841 the proper kernel, there are many cases where this will fail across this 842 upgrade and installworld from single user is required. 843 84420170424: 845 The NATM framework including the en(4), fatm(4), hatm(4), and 846 patm(4) devices has been removed. Consumers should plan a 847 migration before the end-of-life date for FreeBSD 11. 848 84920170420: 850 GNU diff has been replaced by a BSD licensed diff. Some features of GNU 851 diff has not been implemented, if those are needed a newer version of 852 GNU diff is available via the diffutils package under the gdiff name. 853 85420170413: 855 As of r316810 for ipfilter, keep frags is no longer assumed when 856 keep state is specified in a rule. r316810 aligns ipfilter with 857 documentation in man pages separating keep frags from keep state. 858 This allows keep state to be specified without forcing keep frags 859 and allows keep frags to be specified independently of keep state. 860 To maintain previous behaviour, also specify keep frags with 861 keep state (as documented in ipf.conf.5). 862 86320170407: 864 arm64 builds now use the base system LLD 4.0.0 linker by default, 865 instead of requiring that the aarch64-binutils port or package be 866 installed. To continue using aarch64-binutils, set 867 CROSS_BINUTILS_PREFIX=/usr/local/aarch64-freebsd/bin . 868 86920170405: 870 The UDP optimization in entry 20160818 that added the sysctl 871 net.inet.udp.require_l2_bcast has been reverted. L2 broadcast 872 packets will no longer be treated as L3 broadcast packets. 873 87420170331: 875 Binds and sends to the loopback addresses, IPv6 and IPv4, will now 876 use any explicitly assigned loopback address available in the jail 877 instead of using the first assigned address of the jail. 878 87920170329: 880 The ctl.ko module no longer implements the iSCSI target frontend: 881 cfiscsi.ko does instead. 882 883 If building cfiscsi.ko as a kernel module, the module can be loaded 884 via one of the following methods: 885 - `cfiscsi_load="YES"` in loader.conf(5). 886 - Add `cfiscsi` to `$kld_list` in rc.conf(5). 887 - ctladm(8)/ctld(8), when compiled with iSCSI support 888 (`WITH_ISCSI=yes` in src.conf(5)) 889 890 Please see cfiscsi(4) for more details. 891 89220170316: 893 The mmcsd.ko module now additionally depends on geom_flashmap.ko. 894 Also, mmc.ko and mmcsd.ko need to be a matching pair built from the 895 same source (previously, the dependency of mmcsd.ko on mmc.ko was 896 missing, but mmcsd.ko now will refuse to load if it is incompatible 897 with mmc.ko). 898 89920170315: 900 The syntax of ipfw(8) named states was changed to avoid ambiguity. 901 If you have used named states in the firewall rules, you need to modify 902 them after installworld and before rebooting. Now named states must 903 be prefixed with colon. 904 90520170311: 906 The old drm (sys/dev/drm/) drivers for i915 and radeon have been 907 removed as the userland we provide cannot use them. The KMS version 908 (sys/dev/drm2) supports the same hardware. 909 91020170302: 911 Clang, llvm, lldb, compiler-rt and libc++ have been upgraded to 4.0.0. 912 Please see the 20141231 entry below for information about prerequisites 913 and upgrading, if you are not already using clang 3.5.0 or higher. 914 91520170221: 916 The code that provides support for ZFS .zfs/ directory functionality 917 has been reimplemented. It's not possible now to create a snapshot 918 by mkdir under .zfs/snapshot/. That should be the only user visible 919 change. 920 92120170216: 922 EISA bus support has been removed. The WITH_EISA option is no longer 923 valid. 924 92520170215: 926 MCA bus support has been removed. 927 92820170127: 929 The WITH_LLD_AS_LD / WITHOUT_LLD_AS_LD build knobs have been renamed 930 WITH_LLD_IS_LD / WITHOUT_LLD_IS_LD, for consistency with CLANG_IS_CC. 931 93220170112: 933 The EM_MULTIQUEUE kernel configuration option is deprecated now that 934 the em(4) driver conforms to iflib specifications. 935 93620170109: 937 The igb(4), em(4) and lem(4) ethernet drivers are now implemented via 938 IFLIB. If you have a custom kernel configuration that excludes em(4) 939 but you use igb(4), you need to re-add em(4) to your custom 940 configuration. 941 94220161217: 943 Clang, llvm, lldb, compiler-rt and libc++ have been upgraded to 3.9.1. 944 Please see the 20141231 entry below for information about prerequisites 945 and upgrading, if you are not already using clang 3.5.0 or higher. 946 94720161124: 948 Clang, llvm, lldb, compiler-rt and libc++ have been upgraded to 3.9.0. 949 Please see the 20141231 entry below for information about prerequisites 950 and upgrading, if you are not already using clang 3.5.0 or higher. 951 95220161119: 953 The layout of the pmap structure has changed for powerpc to put the pmap 954 statistics at the front for all CPU variations. libkvm(3) and all tools 955 that link against it need to be recompiled. 956 95720161030: 958 isl(4) and cyapa(4) drivers now require a new driver, 959 chromebook_platform(4), to work properly on Chromebook-class hardware. 960 On other types of hardware the drivers may need to be configured using 961 device hints. Please see the corresponding manual pages for details. 962 96320161017: 964 The urtwn(4) driver was merged into rtwn(4) and now consists of 965 rtwn(4) main module + rtwn_usb(4) and rtwn_pci(4) bus-specific 966 parts. 967 Also, firmware for RTL8188CE was renamed due to possible name 968 conflict (rtwnrtl8192cU(B) -> rtwnrtl8192cE(B)) 969 97020161015: 971 GNU rcs has been removed from base. It is available as packages: 972 - rcs: Latest GPLv3 GNU rcs version. 973 - rcs57: Copy of the latest version of GNU rcs (GPLv2) before it was 974 removed from base. 975 97620161008: 977 Use of the cc_cdg, cc_chd, cc_hd, or cc_vegas congestion control 978 modules now requires that the kernel configuration contain the 979 TCP_HHOOK option. (This option is included in the GENERIC kernel.) 980 98120161003: 982 The WITHOUT_ELFCOPY_AS_OBJCOPY src.conf(5) knob has been retired. 983 ELF Tool Chain's elfcopy is always installed as /usr/bin/objcopy. 984 98520160924: 986 Relocatable object files with the extension of .So have been renamed 987 to use an extension of .pico instead. The purpose of this change is 988 to avoid a name clash with shared libraries on case-insensitive file 989 systems. On those file systems, foo.So is the same file as foo.so. 990 99120160918: 992 GNU rcs has been turned off by default. It can (temporarily) be built 993 again by adding WITH_RCS knob in src.conf. 994 Otherwise, GNU rcs is available from packages: 995 - rcs: Latest GPLv3 GNU rcs version. 996 - rcs57: Copy of the latest version of GNU rcs (GPLv2) from base. 997 99820160918: 999 The backup_uses_rcs functionality has been removed from rc.subr. 1000 100120160908: 1002 The queue(3) debugging macro, QUEUE_MACRO_DEBUG, has been split into 1003 two separate components, QUEUE_MACRO_DEBUG_TRACE and 1004 QUEUE_MACRO_DEBUG_TRASH. Define both for the original 1005 QUEUE_MACRO_DEBUG behavior. 1006 100720160824: 1008 r304787 changed some ioctl interfaces between the iSCSI userspace 1009 programs and the kernel. ctladm, ctld, iscsictl, and iscsid must be 1010 rebuilt to work with new kernels. __FreeBSD_version has been bumped 1011 to 1200005. 1012 101320160818: 1014 The UDP receive code has been updated to only treat incoming UDP 1015 packets that were addressed to an L2 broadcast address as L3 1016 broadcast packets. It is not expected that this will affect any 1017 standards-conforming UDP application. The new behaviour can be 1018 disabled by setting the sysctl net.inet.udp.require_l2_bcast to 1019 0. 1020 102120160818: 1022 Remove the openbsd_poll system call. 1023 __FreeBSD_version has been bumped because of this. 1024 102520160708: 1026 The stable/11 branch has been created from head@r302406. 1027 102820160622: 1029 The libc stub for the pipe(2) system call has been replaced with 1030 a wrapper that calls the pipe2(2) system call and the pipe(2) 1031 system call is now only implemented by the kernels that include 1032 "options COMPAT_FREEBSD10" in their config file (this is the 1033 default). Users should ensure that this option is enabled in 1034 their kernel or upgrade userspace to r302092 before upgrading their 1035 kernel. 1036 103720160527: 1038 CAM will now strip leading spaces from SCSI disks' serial numbers. 1039 This will affect users who create UFS filesystems on SCSI disks using 1040 those disk's diskid device nodes. For example, if /etc/fstab 1041 previously contained a line like 1042 "/dev/diskid/DISK-%20%20%20%20%20%20%20ABCDEFG0123456", you should 1043 change it to "/dev/diskid/DISK-ABCDEFG0123456". Users of geom 1044 transforms like gmirror may also be affected. ZFS users should 1045 generally be fine. 1046 104720160523: 1048 The bitstring(3) API has been updated with new functionality and 1049 improved performance. But it is binary-incompatible with the old API. 1050 Objects built with the new headers may not be linked against objects 1051 built with the old headers. 1052 105320160520: 1054 The brk and sbrk functions have been removed from libc on arm64. 1055 Binutils from ports has been updated to not link to these 1056 functions and should be updated to the latest version before 1057 installing a new libc. 1058 105920160517: 1060 The armv6 port now defaults to hard float ABI. Limited support 1061 for running both hardfloat and soft float on the same system 1062 is available using the libraries installed with -DWITH_LIBSOFT. 1063 This has only been tested as an upgrade path for installworld 1064 and packages may fail or need manual intervention to run. New 1065 packages will be needed. 1066 1067 To update an existing self-hosted armv6hf system, you must add 1068 TARGET_ARCH=armv6 on the make command line for both the build 1069 and the install steps. 1070 107120160510: 1072 Kernel modules compiled outside of a kernel build now default to 1073 installing to /boot/modules instead of /boot/kernel. Many kernel 1074 modules built this way (such as those in ports) already overrode 1075 KMODDIR explicitly to install into /boot/modules. However, 1076 manually building and installing a module from /sys/modules will 1077 now install to /boot/modules instead of /boot/kernel. 1078 107920160414: 1080 The CAM I/O scheduler has been committed to the kernel. There should be 1081 no user visible impact. This does enable NCQ Trim on ada SSDs. While the 1082 list of known rogues that claim support for this but actually corrupt 1083 data is believed to be complete, be on the lookout for data 1084 corruption. The known rogue list is believed to be complete: 1085 1086 o Crucial MX100, M550 drives with MU01 firmware. 1087 o Micron M510 and M550 drives with MU01 firmware. 1088 o Micron M500 prior to MU07 firmware 1089 o Samsung 830, 840, and 850 all firmwares 1090 o FCCT M500 all firmwares 1091 1092 Crucial has firmware http://www.crucial.com/usa/en/support-ssd-firmware 1093 with working NCQ TRIM. For Micron branded drives, see your sales rep for 1094 updated firmware. Black listed drives will work correctly because these 1095 drives work correctly so long as no NCQ TRIMs are sent to them. Given 1096 this list is the same as found in Linux, it's believed there are no 1097 other rogues in the market place. All other models from the above 1098 vendors work. 1099 1100 To be safe, if you are at all concerned, you can quirk each of your 1101 drives to prevent NCQ from being sent by setting: 1102 kern.cam.ada.X.quirks="0x2" 1103 in loader.conf. If the drive requires the 4k sector quirk, set the 1104 quirks entry to 0x3. 1105 110620160330: 1107 The FAST_DEPEND build option has been removed and its functionality is 1108 now the one true way. The old mkdep(1) style of 'make depend' has 1109 been removed. See 20160311 for further details. 1110 111120160317: 1112 Resource range types have grown from unsigned long to uintmax_t. All 1113 drivers, and anything using libdevinfo, need to be recompiled. 1114 111520160311: 1116 WITH_FAST_DEPEND is now enabled by default for in-tree and out-of-tree 1117 builds. It no longer runs mkdep(1) during 'make depend', and the 1118 'make depend' stage can safely be skipped now as it is auto ran 1119 when building 'make all' and will generate all SRCS and DPSRCS before 1120 building anything else. Dependencies are gathered at compile time with 1121 -MF flags kept in separate .depend files per object file. Users should 1122 run 'make cleandepend' once if using -DNO_CLEAN to clean out older 1123 stale .depend files. 1124 112520160306: 1126 On amd64, clang 3.8.0 can now insert sections of type AMD64_UNWIND into 1127 kernel modules. Therefore, if you load any kernel modules at boot time, 1128 please install the boot loaders after you install the kernel, but before 1129 rebooting, e.g.: 1130 1131 make buildworld 1132 make buildkernel KERNCONF=YOUR_KERNEL_HERE 1133 make installkernel KERNCONF=YOUR_KERNEL_HERE 1134 make -C sys/boot install 1135 <reboot in single user> 1136 1137 Then follow the usual steps, described in the General Notes section, 1138 below. 1139 114020160305: 1141 Clang, llvm, lldb and compiler-rt have been upgraded to 3.8.0. Please 1142 see the 20141231 entry below for information about prerequisites and 1143 upgrading, if you are not already using clang 3.5.0 or higher. 1144 114520160301: 1146 The AIO subsystem is now a standard part of the kernel. The 1147 VFS_AIO kernel option and aio.ko kernel module have been removed. 1148 Due to stability concerns, asynchronous I/O requests are only 1149 permitted on sockets and raw disks by default. To enable 1150 asynchronous I/O requests on all file types, set the 1151 vfs.aio.enable_unsafe sysctl to a non-zero value. 1152 115320160226: 1154 The ELF object manipulation tool objcopy is now provided by the 1155 ELF Tool Chain project rather than by GNU binutils. It should be a 1156 drop-in replacement, with the addition of arm64 support. The 1157 (temporary) src.conf knob WITHOUT_ELFCOPY_AS_OBJCOPY knob may be set 1158 to obtain the GNU version if necessary. 1159 116020160129: 1161 Building ZFS pools on top of zvols is prohibited by default. That 1162 feature has never worked safely; it's always been prone to deadlocks. 1163 Using a zvol as the backing store for a VM guest's virtual disk will 1164 still work, even if the guest is using ZFS. Legacy behavior can be 1165 restored by setting vfs.zfs.vol.recursive=1. 1166 116720160119: 1168 The NONE and HPN patches has been removed from OpenSSH. They are 1169 still available in the security/openssh-portable port. 1170 117120160113: 1172 With the addition of ypldap(8), a new _ypldap user is now required 1173 during installworld. "mergemaster -p" can be used to add the user 1174 prior to installworld, as documented in the handbook. 1175 117620151216: 1177 The tftp loader (pxeboot) now uses the option root-path directive. As a 1178 consequence it no longer looks for a pxeboot.4th file on the tftp 1179 server. Instead it uses the regular /boot infrastructure as with the 1180 other loaders. 1181 118220151211: 1183 The code to start recording plug and play data into the modules has 1184 been committed. While the old tools will properly build a new kernel, 1185 a number of warnings about "unknown metadata record 4" will be produced 1186 for an older kldxref. To avoid such warnings, make sure to rebuild 1187 the kernel toolchain (or world). Make sure that you have r292078 or 1188 later when trying to build 292077 or later before rebuilding. 1189 119020151207: 1191 Debug data files are now built by default with 'make buildworld' and 1192 installed with 'make installworld'. This facilitates debugging but 1193 requires more disk space both during the build and for the installed 1194 world. Debug files may be disabled by setting WITHOUT_DEBUG_FILES=yes 1195 in src.conf(5). 1196 119720151130: 1198 r291527 changed the internal interface between the nfsd.ko and 1199 nfscommon.ko modules. As such, they must both be upgraded to-gether. 1200 __FreeBSD_version has been bumped because of this. 1201 120220151108: 1203 Add support for unicode collation strings leads to a change of 1204 order of files listed by ls(1) for example. To get back to the old 1205 behaviour, set LC_COLLATE environment variable to "C". 1206 1207 Databases administrators will need to reindex their databases given 1208 collation results will be different. 1209 1210 Due to a bug in install(1) it is recommended to remove the ancient 1211 locales before running make installworld. 1212 1213 rm -rf /usr/share/locale/* 1214 121520151030: 1216 The OpenSSL has been upgraded to 1.0.2d. Any binaries requiring 1217 libcrypto.so.7 or libssl.so.7 must be recompiled. 1218 121920151020: 1220 Qlogic 24xx/25xx firmware images were updated from 5.5.0 to 7.3.0. 1221 Kernel modules isp_2400_multi and isp_2500_multi were removed and 1222 should be replaced with isp_2400 and isp_2500 modules respectively. 1223 122420151017: 1225 The build previously allowed using 'make -n' to not recurse into 1226 sub-directories while showing what commands would be executed, and 1227 'make -n -n' to recursively show commands. Now 'make -n' will recurse 1228 and 'make -N' will not. 1229 123020151012: 1231 If you specify SENDMAIL_MC or SENDMAIL_CF in make.conf, mergemaster 1232 and etcupdate will now use this file. A custom sendmail.cf is now 1233 updated via this mechanism rather than via installworld. If you had 1234 excluded sendmail.cf in mergemaster.rc or etcupdate.conf, you may 1235 want to remove the exclusion or change it to "always install". 1236 /etc/mail/sendmail.cf is now managed the same way regardless of 1237 whether SENDMAIL_MC/SENDMAIL_CF is used. If you are not using 1238 SENDMAIL_MC/SENDMAIL_CF there should be no change in behavior. 1239 124020151011: 1241 Compatibility shims for legacy ATA device names have been removed. 1242 It includes ATA_STATIC_ID kernel option, kern.cam.ada.legacy_aliases 1243 and kern.geom.raid.legacy_aliases loader tunables, kern.devalias.* 1244 environment variables, /dev/ad* and /dev/ar* symbolic links. 1245 124620151006: 1247 Clang, llvm, lldb, compiler-rt and libc++ have been upgraded to 3.7.0. 1248 Please see the 20141231 entry below for information about prerequisites 1249 and upgrading, if you are not already using clang 3.5.0 or higher. 1250 125120150924: 1252 Kernel debug files have been moved to /usr/lib/debug/boot/kernel/, 1253 and renamed from .symbols to .debug. This reduces the size requirements 1254 on the boot partition or file system and provides consistency with 1255 userland debug files. 1256 1257 When using the supported kernel installation method the 1258 /usr/lib/debug/boot/kernel directory will be renamed (to kernel.old) 1259 as is done with /boot/kernel. 1260 1261 Developers wishing to maintain the historical behavior of installing 1262 debug files in /boot/kernel/ can set KERN_DEBUGDIR="" in src.conf(5). 1263 126420150827: 1265 The wireless drivers had undergone changes that remove the 'parent 1266 interface' from the ifconfig -l output. The rc.d network scripts 1267 used to check presence of a parent interface in the list, so old 1268 scripts would fail to start wireless networking. Thus, etcupdate(3) 1269 or mergemaster(8) run is required after kernel update, to update your 1270 rc.d scripts in /etc. 1271 127220150827: 1273 pf no longer supports 'scrub fragment crop' or 'scrub fragment drop-ovl' 1274 These configurations are now automatically interpreted as 1275 'scrub fragment reassemble'. 1276 127720150817: 1278 Kernel-loadable modules for the random(4) device are back. To use 1279 them, the kernel must have 1280 1281 device random 1282 options RANDOM_LOADABLE 1283 1284 kldload(8) can then be used to load random_fortuna.ko 1285 or random_yarrow.ko. Please note that due to the indirect 1286 function calls that the loadable modules need to provide, 1287 the build-in variants will be slightly more efficient. 1288 1289 The random(4) kernel option RANDOM_DUMMY has been retired due to 1290 unpopularity. It was not all that useful anyway. 1291 129220150813: 1293 The WITHOUT_ELFTOOLCHAIN_TOOLS src.conf(5) knob has been retired. 1294 Control over building the ELF Tool Chain tools is now provided by 1295 the WITHOUT_TOOLCHAIN knob. 1296 129720150810: 1298 The polarity of Pulse Per Second (PPS) capture events with the 1299 uart(4) driver has been corrected. Prior to this change the PPS 1300 "assert" event corresponded to the trailing edge of a positive PPS 1301 pulse and the "clear" event was the leading edge of the next pulse. 1302 1303 As the width of a PPS pulse in a typical GPS receiver is on the 1304 order of 1 millisecond, most users will not notice any significant 1305 difference with this change. 1306 1307 Anyone who has compensated for the historical polarity reversal by 1308 configuring a negative offset equal to the pulse width will need to 1309 remove that workaround. 1310 131120150809: 1312 The default group assigned to /dev/dri entries has been changed 1313 from 'wheel' to 'video' with the id of '44'. If you want to have 1314 access to the dri devices please add yourself to the video group 1315 with: 1316 1317 # pw groupmod video -m $USER 1318 131920150806: 1320 The menu.rc and loader.rc files will now be replaced during 1321 upgrades. Please migrate local changes to menu.rc.local and 1322 loader.rc.local instead. 1323 132420150805: 1325 GNU Binutils versions of addr2line, c++filt, nm, readelf, size, 1326 strings and strip have been removed. The src.conf(5) knob 1327 WITHOUT_ELFTOOLCHAIN_TOOLS no longer provides the binutils tools. 1328 132920150728: 1330 As ZFS requires more kernel stack pages than is the default on some 1331 architectures e.g. i386, it now warns if KSTACK_PAGES is less than 1332 ZFS_MIN_KSTACK_PAGES (which is 4 at the time of writing). 1333 1334 Please consider using 'options KSTACK_PAGES=X' where X is greater 1335 than or equal to ZFS_MIN_KSTACK_PAGES i.e. 4 in such configurations. 1336 133720150706: 1338 sendmail has been updated to 8.15.2. Starting with FreeBSD 11.0 1339 and sendmail 8.15, sendmail uses uncompressed IPv6 addresses by 1340 default, i.e., they will not contain "::". For example, instead 1341 of ::1, it will be 0:0:0:0:0:0:0:1. This permits a zero subnet 1342 to have a more specific match, such as different map entries for 1343 IPv6:0:0 vs IPv6:0. This change requires that configuration 1344 data (including maps, files, classes, custom ruleset, etc.) must 1345 use the same format, so make certain such configuration data is 1346 upgrading. As a very simple check search for patterns like 1347 'IPv6:[0-9a-fA-F:]*::' and 'IPv6::'. To return to the old 1348 behavior, set the m4 option confUSE_COMPRESSED_IPV6_ADDRESSES or 1349 the cf option UseCompressedIPv6Addresses. 1350 135120150630: 1352 The default kernel entropy-processing algorithm is now 1353 Fortuna, replacing Yarrow. 1354 1355 Assuming you have 'device random' in your kernel config 1356 file, the configurations allow a kernel option to override 1357 this default. You may choose *ONE* of: 1358 1359 options RANDOM_YARROW # Legacy /dev/random algorithm. 1360 options RANDOM_DUMMY # Blocking-only driver. 1361 1362 If you have neither, you get Fortuna. For most people, 1363 read no further, Fortuna will give a /dev/random that works 1364 like it always used to, and the difference will be irrelevant. 1365 1366 If you remove 'device random', you get *NO* kernel-processed 1367 entropy at all. This may be acceptable to folks building 1368 embedded systems, but has complications. Carry on reading, 1369 and it is assumed you know what you need. 1370 1371 *PLEASE* read random(4) and random(9) if you are in the 1372 habit of tweaking kernel configs, and/or if you are a member 1373 of the embedded community, wanting specific and not-usual 1374 behaviour from your security subsystems. 1375 1376 NOTE!! If you use RANDOM_DUMMY and/or have no 'device 1377 random', you will NOT have a functioning /dev/random, and 1378 many cryptographic features will not work, including SSH. 1379 You may also find strange behaviour from the random(3) set 1380 of library functions, in particular sranddev(3), srandomdev(3) 1381 and arc4random(3). The reason for this is that the KERN_ARND 1382 sysctl only returns entropy if it thinks it has some to 1383 share, and with RANDOM_DUMMY or no 'device random' this 1384 will never happen. 1385 138620150623: 1387 An additional fix for the issue described in the 20150614 sendmail 1388 entry below has been committed in revision 284717. 1389 139020150616: 1391 FreeBSD's old make (fmake) has been removed from the system. It is 1392 available as the devel/fmake port or via pkg install fmake. 1393 139420150615: 1395 The fix for the issue described in the 20150614 sendmail entry 1396 below has been committed in revision 284436. The work 1397 around described in that entry is no longer needed unless the 1398 default setting is overridden by a confDH_PARAMETERS configuration 1399 setting of '5' or pointing to a 512 bit DH parameter file. 1400 140120150614: 1402 ALLOW_DEPRECATED_ATF_TOOLS/ATFFILE support has been removed from 1403 atf.test.mk (included from bsd.test.mk). Please upgrade devel/atf 1404 and devel/kyua to version 0.20+ and adjust any calling code to work 1405 with Kyuafile and kyua. 1406 140720150614: 1408 The import of openssl to address the FreeBSD-SA-15:10.openssl 1409 security advisory includes a change which rejects handshakes 1410 with DH parameters below 768 bits. sendmail releases prior 1411 to 8.15.2 (not yet released), defaulted to a 512 bit 1412 DH parameter setting for client connections. To work around 1413 this interoperability, sendmail can be configured to use a 1414 2048 bit DH parameter by: 1415 1416 1. Edit /etc/mail/`hostname`.mc 1417 2. If a setting for confDH_PARAMETERS does not exist or 1418 exists and is set to a string beginning with '5', 1419 replace it with '2'. 1420 3. If a setting for confDH_PARAMETERS exists and is set to 1421 a file path, create a new file with: 1422 openssl dhparam -out /path/to/file 2048 1423 4. Rebuild the .cf file: 1424 cd /etc/mail/; make; make install 1425 5. Restart sendmail: 1426 cd /etc/mail/; make restart 1427 1428 A sendmail patch is coming, at which time this file will be 1429 updated. 1430 143120150604: 1432 Generation of legacy formatted entries have been disabled by default 1433 in pwd_mkdb(8), as all base system consumers of the legacy formatted 1434 entries were converted to use the new format by default when the new, 1435 machine independent format have been added and supported since FreeBSD 1436 5.x. 1437 1438 Please see the pwd_mkdb(8) manual page for further details. 1439 144020150525: 1441 Clang and llvm have been upgraded to 3.6.1 release. Please see the 1442 20141231 entry below for information about prerequisites and upgrading, 1443 if you are not already using 3.5.0 or higher. 1444 144520150521: 1446 TI platform code switched to using vendor DTS files and this update 1447 may break existing systems running on Beaglebone, Beaglebone Black, 1448 and Pandaboard: 1449 1450 - dtb files should be regenerated/reinstalled. Filenames are the 1451 same but content is different now 1452 - GPIO addressing was changed, now each GPIO bank (32 pins per bank) 1453 has its own /dev/gpiocX device, e.g. pin 121 on /dev/gpioc0 in old 1454 addressing scheme is now pin 25 on /dev/gpioc3. 1455 - Pandaboard: /etc/ttys should be updated, serial console device is 1456 now /dev/ttyu2, not /dev/ttyu0 1457 145820150501: 1459 soelim(1) from gnu/usr.bin/groff has been replaced by usr.bin/soelim. 1460 If you need the GNU extension from groff soelim(1), install groff 1461 from package: pkg install groff, or via ports: textproc/groff. 1462 146320150423: 1464 chmod, chflags, chown and chgrp now affect symlinks in -R mode as 1465 defined in symlink(7); previously symlinks were silently ignored. 1466 146720150415: 1468 The const qualifier has been removed from iconv(3) to comply with 1469 POSIX. The ports tree is aware of this from r384038 onwards. 1470 147120150416: 1472 Libraries specified by LIBADD in Makefiles must have a corresponding 1473 DPADD_<lib> variable to ensure correct dependencies. This is now 1474 enforced in src.libnames.mk. 1475 147620150324: 1477 From legacy ata(4) driver was removed support for SATA controllers 1478 supported by more functional drivers ahci(4), siis(4) and mvs(4). 1479 Kernel modules ataahci and ataadaptec were removed completely, 1480 replaced by ahci and mvs modules respectively. 1481 148220150315: 1483 Clang, llvm and lldb have been upgraded to 3.6.0 release. Please see 1484 the 20141231 entry below for information about prerequisites and 1485 upgrading, if you are not already using 3.5.0 or higher. 1486 148720150307: 1488 The 32-bit PowerPC kernel has been changed to a position-independent 1489 executable. This can only be booted with a version of loader(8) 1490 newer than January 31, 2015, so make sure to update both world and 1491 kernel before rebooting. 1492 149320150217: 1494 If you are running a -CURRENT kernel since r273872 (Oct 30th, 2014), 1495 but before r278950, the RNG was not seeded properly. Immediately 1496 upgrade the kernel to r278950 or later and regenerate any keys (e.g. 1497 ssh keys or openssl keys) that were generated w/ a kernel from that 1498 range. This does not affect programs that directly used /dev/random 1499 or /dev/urandom. All userland uses of arc4random(3) are affected. 1500 150120150210: 1502 The autofs(4) ABI was changed in order to restore binary compatibility 1503 with 10.1-RELEASE. The automountd(8) daemon needs to be rebuilt to work 1504 with the new kernel. 1505 150620150131: 1507 The powerpc64 kernel has been changed to a position-independent 1508 executable. This can only be booted with a new version of loader(8), 1509 so make sure to update both world and kernel before rebooting. 1510 151120150118: 1512 Clang and llvm have been upgraded to 3.5.1 release. This is a bugfix 1513 only release, no new features have been added. Please see the 20141231 1514 entry below for information about prerequisites and upgrading, if you 1515 are not already using 3.5.0. 1516 151720150107: 1518 ELF tools addr2line, elfcopy (strip), nm, size, and strings are now 1519 taken from the ELF Tool Chain project rather than GNU binutils. They 1520 should be drop-in replacements, with the addition of arm64 support. 1521 The WITHOUT_ELFTOOLCHAIN_TOOLS= knob may be used to obtain the 1522 binutils tools, if necessary. See 20150805 for updated information. 1523 152420150105: 1525 The default Unbound configuration now enables remote control 1526 using a local socket. Users who have already enabled the 1527 local_unbound service should regenerate their configuration 1528 by running "service local_unbound setup" as root. 1529 153020150102: 1531 The GNU texinfo and GNU info pages have been removed. 1532 To be able to view GNU info pages please install texinfo from ports. 1533 153420141231: 1535 Clang, llvm and lldb have been upgraded to 3.5.0 release. 1536 1537 As of this release, a prerequisite for building clang, llvm and lldb is 1538 a C++11 capable compiler and C++11 standard library. This means that to 1539 be able to successfully build the cross-tools stage of buildworld, with 1540 clang as the bootstrap compiler, your system compiler or cross compiler 1541 should either be clang 3.3 or later, or gcc 4.8 or later, and your 1542 system C++ library should be libc++, or libdstdc++ from gcc 4.8 or 1543 later. 1544 1545 On any standard FreeBSD 10.x or 11.x installation, where clang and 1546 libc++ are on by default (that is, on x86 or arm), this should work out 1547 of the box. 1548 1549 On 9.x installations where clang is enabled by default, e.g. on x86 and 1550 powerpc, libc++ will not be enabled by default, so libc++ should be 1551 built (with clang) and installed first. If both clang and libc++ are 1552 missing, build clang first, then use it to build libc++. 1553 1554 On 8.x and earlier installations, upgrade to 9.x first, and then follow 1555 the instructions for 9.x above. 1556 1557 Sparc64 and mips users are unaffected, as they still use gcc 4.2.1 by 1558 default, and do not build clang. 1559 1560 Many embedded systems are resource constrained, and will not be able to 1561 build clang in a reasonable time, or in some cases at all. In those 1562 cases, cross building bootable systems on amd64 is a workaround. 1563 1564 This new version of clang introduces a number of new warnings, of which 1565 the following are most likely to appear: 1566 1567 -Wabsolute-value 1568 1569 This warns in two cases, for both C and C++: 1570 * When the code is trying to take the absolute value of an unsigned 1571 quantity, which is effectively a no-op, and almost never what was 1572 intended. The code should be fixed, if at all possible. If you are 1573 sure that the unsigned quantity can be safely cast to signed, without 1574 loss of information or undefined behavior, you can add an explicit 1575 cast, or disable the warning. 1576 1577 * When the code is trying to take an absolute value, but the called 1578 abs() variant is for the wrong type, which can lead to truncation. 1579 If you want to disable the warning instead of fixing the code, please 1580 make sure that truncation will not occur, or it might lead to unwanted 1581 side-effects. 1582 1583 -Wtautological-undefined-compare and 1584 -Wundefined-bool-conversion 1585 1586 These warn when C++ code is trying to compare 'this' against NULL, while 1587 'this' should never be NULL in well-defined C++ code. However, there is 1588 some legacy (pre C++11) code out there, which actively abuses this 1589 feature, which was less strictly defined in previous C++ versions. 1590 1591 Squid and openjdk do this, for example. The warning can be turned off 1592 for C++98 and earlier, but compiling the code in C++11 mode might result 1593 in unexpected behavior; for example, the parts of the program that are 1594 unreachable could be optimized away. 1595 159620141222: 1597 The old NFS client and server (kernel options NFSCLIENT, NFSSERVER) 1598 kernel sources have been removed. The .h files remain, since some 1599 utilities include them. This will need to be fixed later. 1600 If "mount -t oldnfs ..." is attempted, it will fail. 1601 If the "-o" option on mountd(8), nfsd(8) or nfsstat(1) is used, 1602 the utilities will report errors. 1603 160420141121: 1605 The handling of LOCAL_LIB_DIRS has been altered to skip addition of 1606 directories to top level SUBDIR variable when their parent 1607 directory is included in LOCAL_DIRS. Users with build systems with 1608 such hierarchies and without SUBDIR entries in the parent 1609 directory Makefiles should add them or add the directories to 1610 LOCAL_DIRS. 1611 161220141109: 1613 faith(4) and faithd(8) have been removed from the base system. Faith 1614 has been obsolete for a very long time. 1615 161620141104: 1617 vt(4), the new console driver, is enabled by default. It brings 1618 support for Unicode and double-width characters, as well as 1619 support for UEFI and integration with the KMS kernel video 1620 drivers. 1621 1622 You may need to update your console settings in /etc/rc.conf, 1623 most probably the keymap. During boot, /etc/rc.d/syscons will 1624 indicate what you need to do. 1625 1626 vt(4) still has issues and lacks some features compared to 1627 syscons(4). See the wiki for up-to-date information: 1628 https://wiki.freebsd.org/Newcons 1629 1630 If you want to keep using syscons(4), you can do so by adding 1631 the following line to /boot/loader.conf: 1632 kern.vty=sc 1633 163420141102: 1635 pjdfstest has been integrated into kyua as an opt-in test suite. 1636 Please see share/doc/pjdfstest/README for more details on how to 1637 execute it. 1638 163920141009: 1640 gperf has been removed from the base system for architectures 1641 that use clang. Ports that require gperf will obtain it from the 1642 devel/gperf port. 1643 164420140923: 1645 pjdfstest has been moved from tools/regression/pjdfstest to 1646 contrib/pjdfstest . 1647 164820140922: 1649 At svn r271982, The default linux compat kernel ABI has been adjusted 1650 to 2.6.18 in support of the linux-c6 compat ports infrastructure 1651 update. If you wish to continue using the linux-f10 compat ports, 1652 add compat.linux.osrelease=2.6.16 to your local sysctl.conf. Users are 1653 encouraged to update their linux-compat packages to linux-c6 during 1654 their next update cycle. 1655 165620140729: 1657 The ofwfb driver, used to provide a graphics console on PowerPC when 1658 using vt(4), no longer allows mmap() of all physical memory. This 1659 will prevent Xorg on PowerPC with some ATI graphics cards from 1660 initializing properly unless x11-servers/xorg-server is updated to 1661 1.12.4_8 or newer. 1662 166320140723: 1664 The xdev targets have been converted to using TARGET and 1665 TARGET_ARCH instead of XDEV and XDEV_ARCH. 1666 166720140719: 1668 The default unbound configuration has been modified to address 1669 issues with reverse lookups on networks that use private 1670 address ranges. If you use the local_unbound service, run 1671 "service local_unbound setup" as root to regenerate your 1672 configuration, then "service local_unbound reload" to load the 1673 new configuration. 1674 167520140709: 1676 The GNU texinfo and GNU info pages are not built and installed 1677 anymore, WITH_INFO knob has been added to allow to built and install 1678 them again. 1679 UPDATE: see 20150102 entry on texinfo's removal 1680 168120140708: 1682 The GNU readline library is now an INTERNALLIB - that is, it is 1683 statically linked into consumers (GDB and variants) in the base 1684 system, and the shared library is no longer installed. The 1685 devel/readline port is available for third party software that 1686 requires readline. 1687 168820140702: 1689 The Itanium architecture (ia64) has been removed from the list of 1690 known architectures. This is the first step in the removal of the 1691 architecture. 1692 169320140701: 1694 Commit r268115 has added NFSv4.1 server support, merged from 1695 projects/nfsv4.1-server. Since this includes changes to the 1696 internal interfaces between the NFS related modules, a full 1697 build of the kernel and modules will be necessary. 1698 __FreeBSD_version has been bumped. 1699 170020140629: 1701 The WITHOUT_VT_SUPPORT kernel config knob has been renamed 1702 WITHOUT_VT. (The other _SUPPORT knobs have a consistent meaning 1703 which differs from the behaviour controlled by this knob.) 1704 170520140619: 1706 Maximal length of the serial number in CTL was increased from 16 to 1707 64 chars, that breaks ABI. All CTL-related tools, such as ctladm 1708 and ctld, need to be rebuilt to work with a new kernel. 1709 171020140606: 1711 The libatf-c and libatf-c++ major versions were downgraded to 0 and 1712 1 respectively to match the upstream numbers. They were out of 1713 sync because, when they were originally added to FreeBSD, the 1714 upstream versions were not respected. These libraries are private 1715 and not yet built by default, so renumbering them should be a 1716 non-issue. However, unclean source trees will yield broken test 1717 programs once the operator executes "make delete-old-libs" after a 1718 "make installworld". 1719 1720 Additionally, the atf-sh binary was made private by moving it into 1721 /usr/libexec/. Already-built shell test programs will keep the 1722 path to the old binary so they will break after "make delete-old" 1723 is run. 1724 1725 If you are using WITH_TESTS=yes (not the default), wipe the object 1726 tree and rebuild from scratch to prevent spurious test failures. 1727 This is only needed once: the misnumbered libraries and misplaced 1728 binaries have been added to OptionalObsoleteFiles.inc so they will 1729 be removed during a clean upgrade. 1730 173120140512: 1732 Clang and llvm have been upgraded to 3.4.1 release. 1733 173420140508: 1735 We bogusly installed src.opts.mk in /usr/share/mk. This file should 1736 be removed to avoid issues in the future (and has been added to 1737 ObsoleteFiles.inc). 1738 173920140505: 1740 /etc/src.conf now affects only builds of the FreeBSD src tree. In the 1741 past, it affected all builds that used the bsd.*.mk files. The old 1742 behavior was a bug, but people may have relied upon it. To get this 1743 behavior back, you can .include /etc/src.conf from /etc/make.conf 1744 (which is still global and isn't changed). This also changes the 1745 behavior of incremental builds inside the tree of individual 1746 directories. Set MAKESYSPATH to ".../share/mk" to do that. 1747 Although this has survived make universe and some upgrade scenarios, 1748 other upgrade scenarios may have broken. At least one form of 1749 temporary breakage was fixed with MAKESYSPATH settings for buildworld 1750 as well... In cases where MAKESYSPATH isn't working with this 1751 setting, you'll need to set it to the full path to your tree. 1752 1753 One side effect of all this cleaning up is that bsd.compiler.mk 1754 is no longer implicitly included by bsd.own.mk. If you wish to 1755 use COMPILER_TYPE, you must now explicitly include bsd.compiler.mk 1756 as well. 1757 175820140430: 1759 The lindev device has been removed since /dev/full has been made a 1760 standard device. __FreeBSD_version has been bumped. 1761 176220140424: 1763 The knob WITHOUT_VI was added to the base system, which controls 1764 building ex(1), vi(1), etc. Older releases of FreeBSD required ex(1) 1765 in order to reorder files share/termcap and didn't build ex(1) as a 1766 build tool, so building/installing with WITH_VI is highly advised for 1767 build hosts for older releases. 1768 1769 This issue has been fixed in stable/9 and stable/10 in r277022 and 1770 r276991, respectively. 1771 177220140418: 1773 The YES_HESIOD knob has been removed. It has been obsolete for 1774 a decade. Please move to using WITH_HESIOD instead or your builds 1775 will silently lack HESIOD. 1776 177720140405: 1778 The uart(4) driver has been changed with respect to its handling 1779 of the low-level console. Previously the uart(4) driver prevented 1780 any process from changing the baudrate or the CLOCAL and HUPCL 1781 control flags. By removing the restrictions, operators can make 1782 changes to the serial console port without having to reboot. 1783 However, when getty(8) is started on the serial device that is 1784 associated with the low-level console, a misconfigured terminal 1785 line in /etc/ttys will now have a real impact. 1786 Before upgrading the kernel, make sure that /etc/ttys has the 1787 serial console device configured as 3wire without baudrate to 1788 preserve the previous behaviour. E.g: 1789 ttyu0 "/usr/libexec/getty 3wire" vt100 on secure 1790 179120140306: 1792 Support for libwrap (TCP wrappers) in rpcbind was disabled by default 1793 to improve performance. To re-enable it, if needed, run rpcbind 1794 with command line option -W. 1795 179620140226: 1797 Switched back to the GPL dtc compiler due to updates in the upstream 1798 dts files not being supported by the BSDL dtc compiler. You will need 1799 to rebuild your kernel toolchain to pick up the new compiler. Core dumps 1800 may result while building dtb files during a kernel build if you fail 1801 to do so. Set WITHOUT_GPL_DTC if you require the BSDL compiler. 1802 180320140216: 1804 Clang and llvm have been upgraded to 3.4 release. 1805 180620140216: 1807 The nve(4) driver has been removed. Please use the nfe(4) driver 1808 for NVIDIA nForce MCP Ethernet adapters instead. 1809 181020140212: 1811 An ABI incompatibility crept into the libc++ 3.4 import in r261283. 1812 This could cause certain C++ applications using shared libraries built 1813 against the previous version of libc++ to crash. The incompatibility 1814 has now been fixed, but any C++ applications or shared libraries built 1815 between r261283 and r261801 should be recompiled. 1816 181720140204: 1818 OpenSSH will now ignore errors caused by kernel lacking of Capsicum 1819 capability mode support. Please note that enabling the feature in 1820 kernel is still highly recommended. 1821 182220140131: 1823 OpenSSH is now built with sandbox support, and will use sandbox as 1824 the default privilege separation method. This requires Capsicum 1825 capability mode support in kernel. 1826 182720140128: 1828 The libelf and libdwarf libraries have been updated to newer 1829 versions from upstream. Shared library version numbers for 1830 these two libraries were bumped. Any ports or binaries 1831 requiring these two libraries should be recompiled. 1832 __FreeBSD_version is bumped to 1100006. 1833 183420140110: 1835 If a Makefile in a tests/ directory was auto-generating a Kyuafile 1836 instead of providing an explicit one, this would prevent such 1837 Makefile from providing its own Kyuafile in the future during 1838 NO_CLEAN builds. This has been fixed in the Makefiles but manual 1839 intervention is needed to clean an objdir if you use NO_CLEAN: 1840 # find /usr/obj -name Kyuafile | xargs rm -f 1841 184220131213: 1843 The behavior of gss_pseudo_random() for the krb5 mechanism 1844 has changed, for applications requesting a longer random string 1845 than produced by the underlying enctype's pseudo-random() function. 1846 In particular, the random string produced from a session key of 1847 enctype aes256-cts-hmac-sha1-96 or aes256-cts-hmac-sha1-96 will 1848 be different at the 17th octet and later, after this change. 1849 The counter used in the PRF+ construction is now encoded as a 1850 big-endian integer in accordance with RFC 4402. 1851 __FreeBSD_version is bumped to 1100004. 1852 185320131108: 1854 The WITHOUT_ATF build knob has been removed and its functionality 1855 has been subsumed into the more generic WITHOUT_TESTS. If you were 1856 using the former to disable the build of the ATF libraries, you 1857 should change your settings to use the latter. 1858 185920131025: 1860 The default version of mtree is nmtree which is obtained from 1861 NetBSD. The output is generally the same, but may vary 1862 slightly. If you found you need identical output adding 1863 "-F freebsd9" to the command line should do the trick. For the 1864 time being, the old mtree is available as fmtree. 1865 186620131014: 1867 libbsdyml has been renamed to libyaml and moved to /usr/lib/private. 1868 This will break ports-mgmt/pkg. Rebuild the port, or upgrade to pkg 1869 1.1.4_8 and verify bsdyml not linked in, before running "make 1870 delete-old-libs": 1871 # make -C /usr/ports/ports-mgmt/pkg build deinstall install clean 1872 or 1873 # pkg install pkg; ldd /usr/local/sbin/pkg | grep bsdyml 1874 187520131010: 1876 The stable/10 branch has been created in subversion from head 1877 revision r256279. 1878 1879COMMON ITEMS: 1880 1881 General Notes 1882 ------------- 1883 Avoid using make -j when upgrading. While generally safe, there are 1884 sometimes problems using -j to upgrade. If your upgrade fails with 1885 -j, please try again without -j. From time to time in the past there 1886 have been problems using -j with buildworld and/or installworld. This 1887 is especially true when upgrading between "distant" versions (eg one 1888 that cross a major release boundary or several minor releases, or when 1889 several months have passed on the -current branch). 1890 1891 Sometimes, obscure build problems are the result of environment 1892 poisoning. This can happen because the make utility reads its 1893 environment when searching for values for global variables. To run 1894 your build attempts in an "environmental clean room", prefix all make 1895 commands with 'env -i '. See the env(1) manual page for more details. 1896 1897 When upgrading from one major version to another it is generally best to 1898 upgrade to the latest code in the currently installed branch first, then 1899 do an upgrade to the new branch. This is the best-tested upgrade path, 1900 and has the highest probability of being successful. Please try this 1901 approach if you encounter problems with a major version upgrade. Since 1902 the stable 4.x branch point, one has generally been able to upgrade from 1903 anywhere in the most recent stable branch to head / current (or even the 1904 last couple of stable branches). See the top of this file when there's 1905 an exception. 1906 1907 When upgrading a live system, having a root shell around before 1908 installing anything can help undo problems. Not having a root shell 1909 around can lead to problems if pam has changed too much from your 1910 starting point to allow continued authentication after the upgrade. 1911 1912 This file should be read as a log of events. When a later event changes 1913 information of a prior event, the prior event should not be deleted. 1914 Instead, a pointer to the entry with the new information should be 1915 placed in the old entry. Readers of this file should also sanity check 1916 older entries before relying on them blindly. Authors of new entries 1917 should write them with this in mind. 1918 1919 ZFS notes 1920 --------- 1921 When upgrading the boot ZFS pool to a new version, always follow 1922 these two steps: 1923 1924 1.) recompile and reinstall the ZFS boot loader and boot block 1925 (this is part of "make buildworld" and "make installworld") 1926 1927 2.) update the ZFS boot block on your boot drive 1928 1929 The following example updates the ZFS boot block on the first 1930 partition (freebsd-boot) of a GPT partitioned drive ada0: 1931 "gpart bootcode -p /boot/gptzfsboot -i 1 ada0" 1932 1933 Non-boot pools do not need these updates. 1934 1935 To build a kernel 1936 ----------------- 1937 If you are updating from a prior version of FreeBSD (even one just 1938 a few days old), you should follow this procedure. It is the most 1939 failsafe as it uses a /usr/obj tree with a fresh mini-buildworld, 1940 1941 make kernel-toolchain 1942 make -DALWAYS_CHECK_MAKE buildkernel KERNCONF=YOUR_KERNEL_HERE 1943 make -DALWAYS_CHECK_MAKE installkernel KERNCONF=YOUR_KERNEL_HERE 1944 1945 To test a kernel once 1946 --------------------- 1947 If you just want to boot a kernel once (because you are not sure 1948 if it works, or if you want to boot a known bad kernel to provide 1949 debugging information) run 1950 make installkernel KERNCONF=YOUR_KERNEL_HERE KODIR=/boot/testkernel 1951 nextboot -k testkernel 1952 1953 To rebuild everything and install it on the current system. 1954 ----------------------------------------------------------- 1955 # Note: sometimes if you are running current you gotta do more than 1956 # is listed here if you are upgrading from a really old current. 1957 1958 <make sure you have good level 0 dumps> 1959 make buildworld 1960 make buildkernel KERNCONF=YOUR_KERNEL_HERE 1961 make installkernel KERNCONF=YOUR_KERNEL_HERE 1962 [1] 1963 <reboot in single user> [3] 1964 mergemaster -Fp [5] 1965 make installworld 1966 mergemaster -Fi [4] 1967 make delete-old [6] 1968 <reboot> 1969 1970 To cross-install current onto a separate partition 1971 -------------------------------------------------- 1972 # In this approach we use a separate partition to hold 1973 # current's root, 'usr', and 'var' directories.

The defaults can also change, so please read ALL of 2012 the UPDATING entries. 2013 2014 Also, if you are tracking -current, you must be subscribed to 2015 freebsd-current@freebsd.org. Make sure that before you update 2016 your sources that you have read and understood all the recent 2017 messages there. If in doubt, please track -stable which has 2018 much fewer pitfalls. 2019 2020 [1] If you have third party modules, such as vmware, you 2021 should disable them at this point so they don't crash your 2022 system on reboot. 2023 2024 [3] From the bootblocks, boot -s, and then do 2025 fsck -p 2026 mount -u / 2027 mount -a 2028 sh /etc/rc.d/zfs start # mount zfs filesystem, if needed 2029 cd src # full path to source 2030 adjkerntz -i # if CMOS is wall time 2031 Also, when doing a major release upgrade, it is required that 2032 you boot into single user mode to do the installworld. 2033 2034 [4] Note: This step is non-optional. Failure to do this step 2035 can result in a significant reduction in the functionality of the 2036 system. Attempting to do it by hand is not recommended and those 2037 that pursue this avenue should read this file carefully, as well 2038 as the archives of freebsd-current and freebsd-hackers mailing lists 2039 for potential gotchas. The -U option is also useful to consider. 2040 See mergemaster(8) for more information. 2041 2042 [5] Usually this step is a no-op. However, from time to time 2043 you may need to do this if you get unknown user in the following 2044 step. It never hurts to do it all the time. You may need to 2045 install a new mergemaster (cd src/usr.sbin/mergemaster && make 2046 install) after the buildworld before this step if you last updated 2047 from current before 20130425 or from -stable before 20130430. 2048 2049 [6] This only deletes old files and directories. Old libraries 2050 can be deleted by "make delete-old-libs", but you have to make 2051 sure that no program is using those libraries anymore. 2052 2053 [8] The new kernel must be able to run existing binaries used by an 2054 installworld. When upgrading across major versions, the new kernel's 2055 configuration must include the correct COMPAT_FREEBSD<n> option for 2056 existing binaries (e.g. COMPAT_FREEBSD11 to run 11.x binaries). Failure 2057 to do so may leave you with a system that is hard to boot to recover. A 2058 GENERIC kernel will include suitable compatibility options to run 2059 binaries from older branches. Note that the ability to run binaries 2060 from unsupported branches is not guaranteed. 2061 2062 Make sure that you merge any new devices from GENERIC since the 2063 last time you updated your kernel config file. Options also 2064 change over time, so you may need to adjust your custom kernels 2065 for these as well. 2066 2067 [9] If CPUTYPE is defined in your /etc/make.conf, make sure to use the 2068 "?=" instead of the "=" assignment operator, so that buildworld can 2069 override the CPUTYPE if it needs to. 2070 2071 MAKEOBJDIRPREFIX must be defined in an environment variable, and 2072 not on the command line, or in /etc/make.conf. buildworld will 2073 warn if it is improperly defined. 2074FORMAT: 2075 2076This file contains a list, in reverse chronological order, of major 2077breakages in tracking -current. It is not guaranteed to be a complete 2078list of such breakages, and only contains entries since September 23, 2011. 2079If you need to see UPDATING entries from before that date, you will need 2080to fetch an UPDATING file from an older FreeBSD release. 2081 2082Copyright information: 2083 2084Copyright 1998-2009 M.
