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 2920190713: 30 Default permissions on the /var/account/acct file (and copies of it 31 rotated by periodic daily scripts) are changed from 0644 to 0640 32 because the file contains sensitive information that should not be 33 world-readable. If the /var/account directory must be created by 34 rc.d/accounting, the mode used is now 0750. Admins who use the 35 accounting feature are encouraged to change the mode of an existing 36 /var/account directory to 0750 or 0700. 37 3820190620: 39 Entropy collection and the /dev/random device are no longer optional 40 components. The "device random" option has been removed. 41 Implementations of distilling algorithms can still be made loadable 42 with "options RANDOM_LOADABLE" (e.g., random_fortuna.ko). 43 4420190612: 45 Clang, llvm, lld, lldb, compiler-rt, libc++, libunwind and openmp have 46 been upgraded to 8.0.1. Please see the 20141231 entry below for 47 information about prerequisites and upgrading, if you are not already 48 using clang 3.5.0 or higher. 49 5020190608: 51 A fix was applied to i386 kernel modules to avoid panics with 52 dpcpu or vnet. Users need to recompile i386 kernel modules 53 having pcpu or vnet sections or they will refuse to load. 54 5520190513: 56 User-wired pages now have their own counter, 57 vm.stats.vm.v_user_wire_count. The vm.max_wired sysctl was renamed 58 to vm.max_user_wired and changed from an unsigned int to an unsigned 59 long. bhyve VMs wired with the -S are now subject to the user 60 wiring limit; the vm.max_user_wired sysctl may need to be tuned to 61 avoid running into the limit. 62 6320190507: 64 The IPSEC option has been removed from GENERIC. Users requiring 65 ipsec(4) must now load the ipsec(4) kernel module. 66 6720190507: 68 The tap(4) driver has been folded into tun(4), and the module has been 69 renamed to tuntap. You should update any kld_load="if_tap" or 70 kld_load="if_tun" entries in /etc/rc.conf, if_tap_load="YES" or 71 if_tun_load="YES" entries in /boot/loader.conf to load the if_tuntap 72 module instead, and "device tap" or "device tun" entries in kernel 73 config files to select the tuntap device instead. 74 7520190418: 76 The following knobs have been added related to tradeoffs between 77 safe use of the random device and availability in the absence of 78 entropy: 79 80 kern.random.initial_seeding.bypass_before_seeding: tunable; set 81 non-zero to bypass the random device prior to seeding, or zero to 82 block random requests until the random device is initially seeded. 83 For now, set to 1 (unsafe) by default to restore pre-r346250 boot 84 availability properties. 85 86 kern.random.initial_seeding.read_random_bypassed_before_seeding: 87 read-only diagnostic sysctl that is set when bypass is enabled and 88 read_random(9) is bypassed, to enable programmatic handling of this 89 initial condition, if desired. 90 91 kern.random.initial_seeding.arc4random_bypassed_before_seeding: 92 Similar to the above, but for for arc4random(9) initial seeding. 93 94 kern.random.initial_seeding.disable_bypass_warnings: tunable; set 95 non-zero to disable warnings in dmesg when the same conditions are 96 met as for the diagnostic sysctls above. Defaults to zero, i.e., 97 produce warnings in dmesg when the conditions are met. 98 9920190416: 100 The loadable random module KPI has changed; the random_infra_init() 101 routine now requires a 3rd function pointer for a bool (*)(void) 102 method that returns true if the random device is seeded (and 103 therefore unblocked). 104 10520190404: 106 r345895 reverts r320698. This implies that an nfsuserd(8) daemon 107 built from head sources between r320757 (July 6, 2017) and 108 r338192 (Aug. 22, 2018) will not work unless the "-use-udpsock" 109 is added to the command line. 110 nfsuserd daemons built from head sources that are post-r338192 are 111 not affected and should continue to work. 112 11320190320: 114 The fuse(4) module has been renamed to fusefs(4) for consistency with 115 other filesystems. You should update any kld_load="fuse" entries in 116 /etc/rc.conf, fuse_load="YES" entries in /boot/loader.conf, and 117 "options FUSE" entries in kernel config files. 118 11920190304: 120 Clang, llvm, lld, lldb, compiler-rt and libc++ have been upgraded to 121 8.0.0. Please see the 20141231 entry below for information about 122 prerequisites and upgrading, if you are not already using clang 3.5.0 123 or higher. 124 12520190226: 126 geom_uzip(4) depends on the new module xz. If geom_uzip is statically 127 compiled into your custom kernel, add 'device xz' statement to the 128 kernel config. 129 13020190219: 131 drm and drm2 have been removed from the tree. Please see 132 https://wiki.freebsd.org/Graphics for the latest information on 133 migrating to the drm ports. 134 13520190131: 136 Iflib is no longer unconditionally compiled into the kernel. Drivers 137 using iflib and statically compiled into the kernel, now require 138 the 'device iflib' config option. For the same drivers loaded as 139 modules on kernels not having 'device iflib', the iflib.ko module 140 is loaded automatically. 141 14220190125: 143 The IEEE80211_AMPDU_AGE and AH_SUPPORT_AR5416 kernel configuration 144 options no longer exist since r343219 and r343427 respectively; 145 nothing uses them, so they should be just removed from custom 146 kernel config files. 147 14820181230: 149 r342635 changes the way efibootmgr(8) works by requiring users to add 150 the -b (bootnum) parameter for commands where the bootnum was previously 151 specified with each option. For example 'efibootmgr -B 0001' is now 152 'efibootmgr -B -b 0001'. 153 15420181220: 155 r342286 modifies the NFSv4 server so that it obeys vfs.nfsd.nfs_privport 156 in the same as it is applied to NFSv2 and 3. This implies that NFSv4 157 servers that have vfs.nfsd.nfs_privport set will only allow mounts 158 from clients using a reserved port#. Since both the FreeBSD and Linux 159 NFSv4 clients use reserved port#s by default, this should not affect 160 most NFSv4 mounts. 161 16220181219: 163 The XLP config has been removed. We can't support 64-bit atomics in this 164 kernel because it is running in 32-bit mode. XLP users must transition 165 to running a 64-bit kernel (XLP64 or XLPN32). 166 167 The mips GXEMUL support has been removed from FreeBSD. MALTA* + qemu is 168 the preferred emulator today and we don't need two different ones. 169 170 The old sibyte / swarm / Broadcom BCM1250 support has been 171 removed from the mips port. 172 17320181211: 174 Clang, llvm, lld, lldb, compiler-rt and libc++ have been upgraded to 175 7.0.1. Please see the 20141231 entry below for information about 176 prerequisites and upgrading, if you are not already using clang 3.5.0 177 or higher. 178 17920181211: 180 Remove the timed and netdate programs from the base tree. Setting 181 the time with these daemons has been obsolete for over a decade. 182 18320181126: 184 On amd64, arm64 and armv7 (architectures that install LLVM's ld.lld 185 linker as /usr/bin/ld) GNU ld is no longer installed as ld.bfd, as 186 it produces broken binaries when ifuncs are in use. Users needing 187 GNU ld should install the binutils port or package. 188 18920181123: 190 The BSD crtbegin and crtend code has been enabled by default. It has 191 had extensive testing on amd64, arm64, and i386. It can be disabled 192 by building a world with -DWITHOUT_BSD_CRTBEGIN. 193 19420181115: 195 The set of CTM commands (ctm, ctm_smail, ctm_rmail, ctm_dequeue) 196 has been converted to a port (misc/ctm) and will be removed from 197 FreeBSD-13. It is available as a package (ctm) for all supported 198 FreeBSD versions. 199 20020181110: 201 The default newsyslog.conf(5) file has been changed to only include 202 files in /etc/newsyslog.conf.d/ and /usr/local/etc/newsyslog.conf.d/ if 203 the filenames end in '.conf' and do not begin with a '.'. 204 205 You should check the configuration files in these two directories match 206 this naming convention. You can verify which configuration files are 207 being included using the command: 208 $ newsyslog -Nrv 209 21020181015: 211 Ports for the DRM modules have been simplified. Now, amd64 users should 212 just install the drm-kmod port. All others should install 213 drm-legacy-kmod. 214 215 Graphics hardware that's newer than about 2010 usually works with 216 drm-kmod. For hardware older than 2013, however, some users will need 217 to use drm-legacy-kmod if drm-kmod doesn't work for them. Hardware older 218 than 2008 usually only works in drm-legacy-kmod. The graphics team can 219 only commit to hardware made since 2013 due to the complexity of the 220 market and difficulty to test all the older cards effectively. If you 221 have hardware supported by drm-kmod, you are strongly encouraged to use 222 that as you will get better support. 223 224 Other than KPI chasing, drm-legacy-kmod will not be updated. As outlined 225 elsewhere, the drm and drm2 modules will be eliminated from the src base 226 soon (with a limited exception for arm). Please update to the package 227 asap and report any issues to x11@freebsd.org. 228 229 Generally, anybody using the drm*-kmod packages should add 230 WITHOUT_DRM_MODULE=t and WITHOUT_DRM2_MODULE=t to avoid nasty 231 cross-threading surprises, especially with automatic driver 232 loading from X11 startup. These will become the defaults in 13-current 233 shortly. 234 23520181012: 236 The ixlv(4) driver has been renamed to iavf(4). As a consequence, 237 custom kernel and module loading configuration files must be updated 238 accordingly. Moreover, interfaces previous presented as ixlvN to the 239 system are now exposed as iavfN and network configuration files must 240 be adjusted as necessary. 241 24220181009: 243 OpenSSL has been updated to version 1.1.1. This update included 244 additional various API changes throughout the base system. It is 245 important to rebuild third-party software after upgrading. The value 246 of __FreeBSD_version has been bumped accordingly. 247 24820181006: 249 The legacy DRM modules and drivers have now been added to the loader's 250 module blacklist, in favor of loading them with kld_list in rc.conf(5). 251 The module blacklist may be overridden with the loader.conf(5) 252 'module_blacklist' variable, but loading them via rc.conf(5) is strongly 253 encouraged. 254 25520181002: 256 The cam(4) based nda(4) driver will be used over nvd(4) by default on 257 powerpc64. You may set 'options NVME_USE_NVD=1' in your kernel conf or 258 loader tunable 'hw.nvme.use_nvd=1' if you wish to use the existing 259 driver. Make sure to edit /boot/etc/kboot.conf and fstab to use the 260 nda device name. 261 26220180913: 263 Reproducible build mode is now on by default, in preparation for 264 FreeBSD 12.0. This eliminates build metadata such as the user, 265 host, and time from the kernel (and uname), unless the working tree 266 corresponds to a modified checkout from a version control system. 267 The previous behavior can be obtained by setting the /etc/src.conf 268 knob WITHOUT_REPRODUCIBLE_BUILD. 269 27020180826: 271 The Yarrow CSPRNG has been removed from the kernel as it has not been 272 supported by its designers since at least 2003. Fortuna has been the 273 default since FreeBSD-11. 274 27520180822: 276 devctl freeze/thaw have gone into the tree, the rc scripts have been 277 updated to use them and devmatch has been changed. You should update 278 kernel, userland and rc scripts all at the same time. 279 28020180818: 281 The default interpreter has been switched from 4th to Lua. 282 LOADER_DEFAULT_INTERP, documented in build(7), will override the default 283 interpreter. If you have custom FORTH code you will need to set 284 LOADER_DEFAULT_INTERP=4th (valid values are 4th, lua or simp) in 285 src.conf for the build. This will create default hard links between 286 loader and loader_4th instead of loader and loader_lua, the new default. 287 If you are using UEFI it will create the proper hard link to loader.efi. 288 289 bhyve uses userboot.so. It remains 4th-only until some issues are solved 290 regarding coexisting with multiple versions of FreeBSD are resolved. 291 29220180815: 293 ls(1) now respects the COLORTERM environment variable used in other 294 systems and software to indicate that a colored terminal is both 295 supported and desired. If ls(1) is suddenly emitting colors, they may 296 be disabled again by either removing the unwanted COLORTERM from your 297 environment, or using `ls --color=never`. The ls(1) specific CLICOLOR 298 may not be observed in a future release. 299 30020180808: 301 The default pager for most commands has been changed to "less". To 302 restore the old behavior, set PAGER="more" and MANPAGER="more -s" in 303 your environment. 304 30520180731: 306 The jedec_ts(4) driver has been removed. A superset of its functionality 307 is available in the jedec_dimm(4) driver, and the manpage for that 308 driver includes migration instructions. If you have "device jedec_ts" 309 in your kernel configuration file, it must be removed. 310 31120180730: 312 amd64/GENERIC now has EFI runtime services, EFIRT, enabled by default. 313 This should have no effect if the kernel is booted via BIOS/legacy boot. 314 EFIRT may be disabled via a loader tunable, efi.rt.disabled, if a system 315 has a buggy firmware that prevents a successful boot due to use of 316 runtime services. 317 31820180727: 319 Atmel AT91RM9200 and AT91SAM9, Cavium CNS 11xx and XScale 320 support has been removed from the tree. These ports were 321 obsolete and/or known to be broken for many years. 322 32320180723: 324 loader.efi has been augmented to participate more fully in the 325 UEFI boot manager protocol. loader.efi will now look at the 326 BootXXXX environment variable to determine if a specific kernel 327 or root partition was specified. XXXX is derived from BootCurrent. 328 efibootmgr(8) manages these standard UEFI variables. 329 33020180720: 331 zfsloader's functionality has now been folded into loader. 332 zfsloader is no longer necessary once you've updated your 333 boot blocks. For a transition period, we will install a 334 hardlink for zfsloader to loader to allow a smooth transition 335 until the boot blocks can be updated (hard link because old 336 zfs boot blocks don't understand symlinks). 337 33820180719: 339 ARM64 now have efifb support, if you want to have serial console 340 on your arm64 board when an screen is connected and the bootloader 341 setup a frame buffer for us to use, just add : 342 boot_serial=YES 343 boot_multicons=YES 344 in /boot/loader.conf 345 For Raspberry Pi 3 (RPI) users, this is needed even if you don't have 346 an screen connected as the firmware will setup a frame buffer are that 347 u-boot will expose as an EFI frame buffer. 348 34920180719: 350 New uid:gid added, ntpd:ntpd (123:123). Be sure to run mergemaster 351 or take steps to update /etc/passwd before doing installworld on 352 existing systems. Do not skip the "mergemaster -Fp" step before 353 installworld, as described in the update procedures near the bottom 354 of this document. Also, rc.d/ntpd now starts ntpd(8) as user ntpd 355 if the new mac_ntpd(4) policy is available, unless ntpd_flags or 356 the ntp config file contain options that change file/dir locations. 357 When such options (e.g., "statsdir" or "crypto") are used, ntpd can 358 still be run as non-root by setting ntpd_user=ntpd in rc.conf, after 359 taking steps to ensure that all required files/dirs are accessible 360 by the ntpd user. 361 36220180717: 363 Big endian arm support has been removed. 364 36520180711: 366 The static environment setup in kernel configs is no longer mutually 367 exclusive with the loader(8) environment by default. In order to 368 restore the previous default behavior of disabling the loader(8) 369 environment if a static environment is present, you must specify 370 loader_env.disabled=1 in the static environment. 371 37220180705: 373 The ABI of syscalls used by management tools like sockstat and 374 netstat has been broken to allow 32-bit binaries to work on 375 64-bit kernels without modification. These programs will need 376 to match the kernel in order to function. External programs may 377 require minor modifications to accommodate a change of type in 378 structures from pointers to 64-bit virtual addresses. 379 38020180702: 381 On i386 and amd64 atomics are now inlined. Out of tree modules using 382 atomics will need to be rebuilt. 383 38420180701: 385 The '%I' format in the kern.corefile sysctl limits the number of 386 core files that a process can generate to the number stored in the 387 debug.ncores sysctl. The '%I' format is replaced by the single digit 388 index. Previously, if all indexes were taken the kernel would overwrite 389 only a core file with the highest index in a filename. 390 Currently the system will create a new core file if there is a free 391 index or if all slots are taken it will overwrite the oldest one. 392 39320180630: 394 Clang, llvm, lld, lldb, compiler-rt and libc++ have been upgraded to 395 6.0.1. Please see the 20141231 entry below for information about 396 prerequisites and upgrading, if you are not already using clang 3.5.0 397 or higher. 398 39920180628: 400 r335753 introduced a new quoting method. However, etc/devd/devmatch.conf 401 needed to be changed to work with it. This change was made with r335763 402 and requires a mergemaster / etcupdate / etc to update the installed 403 file. 404 40520180612: 406 r334930 changed the interface between the NFS modules, so they all 407 need to be rebuilt. r335018 did a __FreeBSD_version bump for this. 408 40920180530: 410 As of r334391 lld is the default amd64 system linker; it is installed 411 as /usr/bin/ld. Kernel build workarounds (see 20180510 entry) are no 412 longer necessary. 413 41420180530: 415 The kernel / userland interface for devinfo changed, so you'll 416 need a new kernel and userland as a pair for it to work (rebuilding 417 lib/libdevinfo is all that's required). devinfo and devmatch will 418 not work, but everything else will when there's a mismatch. 419 42020180523: 421 The on-disk format for hwpmc callchain records has changed to include 422 threadid corresponding to a given record. This changes the field offsets 423 and thus requires that libpmcstat be rebuilt before using a kernel 424 later than r334108. 425 42620180517: 427 The vxge(4) driver has been removed. This driver was introduced into 428 HEAD one week before the Exar left the Ethernet market and is not 429 known to be used. If you have device vxge in your kernel config file 430 it must be removed. 431 43220180510: 433 The amd64 kernel now requires a ld that supports ifunc to produce a 434 working kernel, either lld or a newer binutils. lld is built by default 435 on amd64, and the 'buildkernel' target uses it automatically. However, 436 it is not the default linker, so building the kernel the traditional 437 way requires LD=ld.lld on the command line (or LD=/usr/local/bin/ld for 438 binutils port/package). lld will soon be default, and this requirement 439 will go away. 440 441 NOTE: As of r334391 lld is the default system linker on amd64, and no 442 workaround is necessary. 443 44420180508: 445 The nxge(4) driver has been removed. This driver was for PCI-X 10g 446 cards made by s2io/Neterion. The company was acquired by Exar and 447 no longer sells or supports Ethernet products. If you have device 448 nxge in your kernel config file it must be removed. 449 45020180504: 451 The tz database (tzdb) has been updated to 2018e. This version more 452 correctly models time stamps in time zones with negative DST such as 453 Europe/Dublin (from 1971 on), Europe/Prague (1946/7), and 454 Africa/Windhoek (1994/2017). This does not affect the UT offsets, only 455 time zone abbreviations and the tm_isdst flag. 456 45720180502: 458 The ixgb(4) driver has been removed. This driver was for an early and 459 uncommon legacy PCI 10GbE for a single ASIC, Intel 82597EX. Intel 460 quickly shifted to the long lived ixgbe family. If you have device 461 ixgb in your kernel config file it must be removed. 462 46320180501: 464 The lmc(4) driver has been removed. This was a WAN interface 465 card that was already reportedly rare in 2003, and had an ambiguous 466 license. If you have device lmc in your kernel config file it must 467 be removed. 468 46920180413: 470 Support for Arcnet networks has been removed. If you have device 471 arcnet or device cm in your kernel config file they must be 472 removed. 473 47420180411: 475 Support for FDDI networks has been removed. If you have device 476 fddi or device fpa in your kernel config file they must be 477 removed. 478 47920180406: 480 In addition to supporting RFC 3164 formatted messages, the 481 syslogd(8) service is now capable of parsing RFC 5424 formatted 482 log messages. The main benefit of using RFC 5424 is that clients 483 may now send log messages with timestamps containing year numbers, 484 microseconds and time zone offsets. 485 486 Similarly, the syslog(3) C library function has been altered to 487 send RFC 5424 formatted messages to the local system logging 488 daemon. On systems using syslogd(8), this change should have no 489 negative impact, as long as syslogd(8) and the C library are 490 updated at the same time. On systems using a different system 491 logging daemon, it may be necessary to make configuration 492 adjustments, depending on the software used. 493 494 When using syslog-ng, add the 'syslog-protocol' flag to local 495 input sources to enable parsing of RFC 5424 formatted messages: 496 497 source src { 498 unix-dgram("/var/run/log" flags(syslog-protocol)); 499 } 500 501 When using rsyslog, disable the 'SysSock.UseSpecialParser' option 502 of the 'imuxsock' module to let messages be processed by the 503 regular RFC 3164/5424 parsing pipeline: 504 505 module(load="imuxsock" SysSock.UseSpecialParser="off") 506 507 Do note that these changes only affect communication between local 508 applications and syslogd(8). The format that syslogd(8) uses to 509 store messages on disk or forward messages to other systems 510 remains unchanged. syslogd(8) still uses RFC 3164 for these 511 purposes. Options to customize this behaviour will be added in the 512 future. Utilities that process log files stored in /var/log are 513 thus expected to continue to function as before. 514 515 __FreeBSD_version has been incremented to 1200061 to denote this 516 change. 517 51820180328: 519 Support for token ring networks has been removed. If you 520 have "device token" in your kernel config you should remove 521 it. No device drivers supported token ring. 522 52320180323: 524 makefs was modified to be able to tag ISO9660 El Torito boot catalog 525 entries as EFI instead of overloading the i386 tag as done previously. 526 The amd64 mkisoimages.sh script used to build amd64 ISO images for 527 release was updated to use this. This may mean that makefs must be 528 updated before "make cdrom" can be run in the release directory. This 529 should be as simple as: 530 531 $ cd $SRCDIR/usr.sbin/makefs 532 $ make depend all install 533 53420180212: 535 FreeBSD boot loader enhanced with Lua scripting. It's purely opt-in for 536 now by building WITH_LOADER_LUA and WITHOUT_FORTH in /etc/src.conf. 537 Co-existence for the transition period will come shortly. Booting is a 538 complex environment and test coverage for Lua-enabled loaders has been 539 thin, so it would be prudent to assume it might not work and make 540 provisions for backup boot methods. 541 54220180211: 543 devmatch functionality has been turned on in devd. It will automatically 544 load drivers for unattached devices. This may cause unexpected drivers 545 to be loaded. Please report any problems to current@ and 546 imp@freebsd.org. 547 54820180114: 549 Clang, llvm, lld, lldb, compiler-rt and libc++ have been upgraded to 550 6.0.0. Please see the 20141231 entry below for information about 551 prerequisites and upgrading, if you are not already using clang 3.5.0 552 or higher. 553 55420180110: 555 LLVM's lld linker is now used as the FreeBSD/amd64 bootstrap linker. 556 This means it is used to link the kernel and userland libraries and 557 executables, but is not yet installed as /usr/bin/ld by default. 558 559 To revert to ld.bfd as the bootstrap linker, in /etc/src.conf set 560 WITHOUT_LLD_BOOTSTRAP=yes 561 56220180110: 563 On i386, pmtimer has been removed. Its functionality has been folded 564 into apm. It was a no-op on ACPI in current for a while now (but was 565 still needed on i386 in FreeBSD 11 and earlier). Users may need to 566 remove it from kernel config files. 567 56820180104: 569 The use of RSS hash from the network card aka flowid has been 570 disabled by default for lagg(4) as it's currently incompatible with 571 the lacp and loadbalance protocols. 572 573 This can be re-enabled by setting the following in loader.conf: 574 net.link.lagg.default_use_flowid="1" 575 57620180102: 577 The SW_WATCHDOG option is no longer necessary to enable the 578 hardclock-based software watchdog if no hardware watchdog is 579 configured. As before, SW_WATCHDOG will cause the software 580 watchdog to be enabled even if a hardware watchdog is configured. 581 58220171215: 583 r326887 fixes the issue described in the 20171214 UPDATING entry. 584 r326888 flips the switch back to building GELI support always. 585 58620171214: 587 r362593 broke ZFS + GELI support for reasons unknown. However, 588 it also broke ZFS support generally, so GELI has been turned off 589 by default as the lesser evil in r326857. If you boot off ZFS and/or 590 GELI, it might not be a good time to update. 591 59220171125: 593 PowerPC users must update loader(8) by rebuilding world before 594 installing a new kernel, as the protocol connecting them has 595 changed. Without the update, loader metadata will not be passed 596 successfully to the kernel and users will have to enter their 597 root partition at the kernel mountroot prompt to continue booting. 598 Newer versions of loader can boot old kernels without issue. 599 60020171110: 601 The LOADER_FIREWIRE_SUPPORT build variable as been renamed to 602 WITH/OUT_LOADER_FIREWIRE. LOADER_{NO_,}GELI_SUPPORT has been renamed 603 to WITH/OUT_LOADER_GELI. 604 60520171106: 606 The naive and non-compliant support of posix_fallocate(2) in ZFS 607 has been removed as of r325320. The system call now returns EINVAL 608 when used on a ZFS file. Although the new behavior complies with the 609 standard, some consumers are not prepared to cope with it. 610 One known victim is lld prior to r325420. 611 61220171102: 613 Building in a FreeBSD src checkout will automatically create object 614 directories now rather than store files in the current directory if 615 'make obj' was not ran. Calling 'make obj' is no longer necessary. 616 This feature can be disabled by setting WITHOUT_AUTO_OBJ=yes in 617 /etc/src-env.conf (not /etc/src.conf), or passing the option in the 618 environment. 619 62020171101: 621 The default MAKEOBJDIR has changed from /usr/obj/<srcdir> for native 622 builds, and /usr/obj/<arch>/<srcdir> for cross-builds, to a unified 623 /usr/obj/<srcdir>/<arch>. This behavior can be changed to the old 624 format by setting WITHOUT_UNIFIED_OBJDIR=yes in /etc/src-env.conf, 625 the environment, or with -DWITHOUT_UNIFIED_OBJDIR when building. 626 The UNIFIED_OBJDIR option is a transitional feature that will be 627 removed for 12.0 release; please migrate to the new format for any 628 tools by looking up the OBJDIR used by 'make -V .OBJDIR' means rather 629 than hardcoding paths. 630 63120171028: 632 The native-xtools target no longer installs the files by default to the 633 OBJDIR. Use the native-xtools-install target with a DESTDIR to install 634 to ${DESTDIR}/${NXTP} where NXTP defaults to /nxb-bin. 635 63620171021: 637 As part of the boot loader infrastructure cleanup, LOADER_*_SUPPORT 638 options are changing from controlling the build if defined / undefined 639 to controlling the build with explicit 'yes' or 'no' values. They will 640 shift to WITH/WITHOUT options to match other options in the system. 641 64220171010: 643 libstand has turned into a private library for sys/boot use only. 644 It is no longer supported as a public interface outside of sys/boot. 645 64620171005: 647 The arm port has split armv6 into armv6 and armv7. armv7 is now 648 a valid TARGET_ARCH/MACHINE_ARCH setting. If you have an armv7 system 649 and are running a kernel from before r324363, you will need to add 650 MACHINE_ARCH=armv7 to 'make buildworld' to do a native build. 651 65220171003: 653 When building multiple kernels using KERNCONF, non-existent KERNCONF 654 files will produce an error and buildkernel will fail. Previously 655 missing KERNCONF files silently failed giving no indication as to 656 why, only to subsequently discover during installkernel that the 657 desired kernel was never built in the first place. 658 65920170912: 660 The default serial number format for CTL LUNs has changed. This will 661 affect users who use /dev/diskid/* device nodes, or whose FibreChannel 662 or iSCSI clients care about their LUNs' serial numbers. Users who 663 require serial number stability should hardcode serial numbers in 664 /etc/ctl.conf . 665 66620170912: 667 For 32-bit arm compiled for hard-float support, soft-floating point 668 binaries now always get their shared libraries from 669 LD_SOFT_LIBRARY_PATH (in the past, this was only used if 670 /usr/libsoft also existed). Only users with a hard-float ld.so, but 671 soft-float everything else should be affected. 672 67320170826: 674 The geli password typed at boot is now hidden. To restore the previous 675 behavior, see geli(8) for configuration options. 676 67720170825: 678 Move PMTUD blackhole counters to TCPSTATS and remove them from bare 679 sysctl values. Minor nit, but requires a rebuild of both world/kernel 680 to complete. 681 68220170814: 683 "make check" behavior (made in ^/head@r295380) has been changed to 684 execute from a limited sandbox, as opposed to executing from 685 ${TESTSDIR}. 686 687 Behavioral changes: 688 - The "beforecheck" and "aftercheck" targets are now specified. 689 - ${CHECKDIR} (added in commit noted above) has been removed. 690 - Legacy behavior can be enabled by setting 691 WITHOUT_MAKE_CHECK_USE_SANDBOX in src.conf(5) or the environment. 692 693 If the limited sandbox mode is enabled, "make check" will execute 694 "make distribution", then install, execute the tests, and clean up the 695 sandbox if successful. 696 697 The "make distribution" and "make install" targets are typically run as 698 root to set appropriate permissions and ownership at installation time. 699 The end-user should set "WITH_INSTALL_AS_USER" in src.conf(5) or the 700 environment if executing "make check" with limited sandbox mode using 701 an unprivileged user. 702 70320170808: 704 Since the switch to GPT disk labels, fsck for UFS/FFS has been 705 unable to automatically find alternate superblocks. As of r322297, 706 the information needed to find alternate superblocks has been 707 moved to the end of the area reserved for the boot block. 708 Filesystems created with a newfs of this vintage or later 709 will create the recovery information. If you have a filesystem 710 created prior to this change and wish to have a recovery block 711 created for your filesystem, you can do so by running fsck in 712 foreground mode (i.e., do not use the -p or -y options). As it 713 starts, fsck will ask ``SAVE DATA TO FIND ALTERNATE SUPERBLOCKS'' 714 to which you should answer yes. 715 71620170728: 717 As of r321665, an NFSv4 server configuration that services 718 Kerberos mounts or clients that do not support the uid/gid in 719 owner/owner_group string capability, must explicitly enable 720 the nfsuserd daemon by adding nfsuserd_enable="YES" to the 721 machine's /etc/rc.conf file. 722 72320170722: 724 Clang, llvm, lldb, compiler-rt and libc++ have been upgraded to 5.0.0. 725 Please see the 20141231 entry below for information about prerequisites 726 and upgrading, if you are not already using clang 3.5.0 or higher. 727 72820170701: 729 WITHOUT_RCMDS is now the default. Set WITH_RCMDS if you need the 730 r-commands (rlogin, rsh, etc.) to be built with the base system. 731 73220170625: 733 The FreeBSD/powerpc platform now uses a 64-bit type for time_t. This is 734 a very major ABI incompatible change, so users of FreeBSD/powerpc must 735 be careful when performing source upgrades. It is best to run 736 'make installworld' from an alternate root system, either a live 737 CD/memory stick, or a temporary root partition. Additionally, all ports 738 must be recompiled. powerpc64 is largely unaffected, except in the case 739 of 32-bit compatibility. All 32-bit binaries will be affected. 740 74120170623: 742 Forward compatibility for the "ino64" project have been committed. This 743 will allow most new binaries to run on older kernels in a limited 744 fashion. This prevents many of the common foot-shooting actions in the 745 upgrade as well as the limited ability to roll back the kernel across 746 the ino64 upgrade. Complicated use cases may not work properly, though 747 enough simpler ones work to allow recovery in most situations. 748 74920170620: 750 Switch back to the BSDL dtc (Device Tree Compiler). Set WITH_GPL_DTC 751 if you require the GPL compiler. 752 75320170618: 754 The internal ABI used for communication between the NFS kernel modules 755 was changed by r320085, so __FreeBSD_version was bumped to 756 ensure all the NFS related modules are updated together. 757 75820170617: 759 The ABI of struct event was changed by extending the data 760 member to 64bit and adding ext fields. For upgrade, same 761 precautions as for the entry 20170523 "ino64" must be 762 followed. 763 76420170531: 765 The GNU roff toolchain has been removed from base. To render manpages 766 which are not supported by mandoc(1), man(1) can fallback on GNU roff 767 from ports (and recommends to install it). 768 To render roff(7) documents, consider using GNU roff from ports or the 769 heirloom doctools roff toolchain from ports via pkg install groff or 770 via pkg install heirloom-doctools. 771 77220170524: 773 The ath(4) and ath_hal(4) modules now build piecemeal to allow for 774 smaller runtime footprint builds. This is useful for embedded systems 775 which only require one chipset support. 776 777 If you load it as a module, make sure this is in /boot/loader.conf: 778 779 if_ath_load="YES" 780 781 This will load the HAL, all chip/RF backends and if_ath_pci. 782 If you have if_ath_pci in /boot/loader.conf, ensure it is after 783 if_ath or it will not load any HAL chipset support. 784 785 If you want to selectively load things (eg on ye cheape ARM/MIPS 786 platforms where RAM is at a premium) you should: 787 788 * load ath_hal 789 * load the chip modules in question 790 * load ath_rate, ath_dfs 791 * load ath_main 792 * load if_ath_pci and/or if_ath_ahb depending upon your particular 793 bus bind type - this is where probe/attach is done. 794 795 For further comments/feedback, poke adrian@ . 796 79720170523: 798 The "ino64" 64-bit inode project has been committed, which extends 799 a number of types to 64 bits. Upgrading in place requires care and 800 adherence to the documented upgrade procedure. 801 802 If using a custom kernel configuration ensure that the 803 COMPAT_FREEBSD11 option is included (as during the upgrade the 804 system will be running the ino64 kernel with the existing world). 805 806 For the safest in-place upgrade begin by removing previous build 807 artifacts via "rm -rf /usr/obj/*". Then, carefully follow the full 808 procedure documented below under the heading "To rebuild everything and 809 install it on the current system." Specifically, a reboot is required 810 after installing the new kernel before installing world. While an 811 installworld normally works by accident from multiuser after rebooting 812 the proper kernel, there are many cases where this will fail across this 813 upgrade and installworld from single user is required. 814 81520170424: 816 The NATM framework including the en(4), fatm(4), hatm(4), and 817 patm(4) devices has been removed. Consumers should plan a 818 migration before the end-of-life date for FreeBSD 11. 819 82020170420: 821 GNU diff has been replaced by a BSD licensed diff. Some features of GNU 822 diff has not been implemented, if those are needed a newer version of 823 GNU diff is available via the diffutils package under the gdiff name. 824 82520170413: 826 As of r316810 for ipfilter, keep frags is no longer assumed when 827 keep state is specified in a rule. r316810 aligns ipfilter with 828 documentation in man pages separating keep frags from keep state. 829 This allows keep state to be specified without forcing keep frags 830 and allows keep frags to be specified independently of keep state. 831 To maintain previous behaviour, also specify keep frags with 832 keep state (as documented in ipf.conf.5). 833 83420170407: 835 arm64 builds now use the base system LLD 4.0.0 linker by default, 836 instead of requiring that the aarch64-binutils port or package be 837 installed. To continue using aarch64-binutils, set 838 CROSS_BINUTILS_PREFIX=/usr/local/aarch64-freebsd/bin . 839 84020170405: 841 The UDP optimization in entry 20160818 that added the sysctl 842 net.inet.udp.require_l2_bcast has been reverted. L2 broadcast 843 packets will no longer be treated as L3 broadcast packets. 844 84520170331: 846 Binds and sends to the loopback addresses, IPv6 and IPv4, will now 847 use any explicitly assigned loopback address available in the jail 848 instead of using the first assigned address of the jail. 849 85020170329: 851 The ctl.ko module no longer implements the iSCSI target frontend: 852 cfiscsi.ko does instead. 853 854 If building cfiscsi.ko as a kernel module, the module can be loaded 855 via one of the following methods: 856 - `cfiscsi_load="YES"` in loader.conf(5). 857 - Add `cfiscsi` to `$kld_list` in rc.conf(5). 858 - ctladm(8)/ctld(8), when compiled with iSCSI support 859 (`WITH_ISCSI=yes` in src.conf(5)) 860 861 Please see cfiscsi(4) for more details. 862 86320170316: 864 The mmcsd.ko module now additionally depends on geom_flashmap.ko. 865 Also, mmc.ko and mmcsd.ko need to be a matching pair built from the 866 same source (previously, the dependency of mmcsd.ko on mmc.ko was 867 missing, but mmcsd.ko now will refuse to load if it is incompatible 868 with mmc.ko). 869 87020170315: 871 The syntax of ipfw(8) named states was changed to avoid ambiguity. 872 If you have used named states in the firewall rules, you need to modify 873 them after installworld and before rebooting. Now named states must 874 be prefixed with colon. 875 87620170311: 877 The old drm (sys/dev/drm/) drivers for i915 and radeon have been 878 removed as the userland we provide cannot use them. The KMS version 879 (sys/dev/drm2) supports the same hardware. 880 88120170302: 882 Clang, llvm, lldb, compiler-rt and libc++ have been upgraded to 4.0.0. 883 Please see the 20141231 entry below for information about prerequisites 884 and upgrading, if you are not already using clang 3.5.0 or higher. 885 88620170221: 887 The code that provides support for ZFS .zfs/ directory functionality 888 has been reimplemented. It's not possible now to create a snapshot 889 by mkdir under .zfs/snapshot/. That should be the only user visible 890 change. 891 89220170216: 893 EISA bus support has been removed. The WITH_EISA option is no longer 894 valid. 895 89620170215: 897 MCA bus support has been removed. 898 89920170127: 900 The WITH_LLD_AS_LD / WITHOUT_LLD_AS_LD build knobs have been renamed 901 WITH_LLD_IS_LD / WITHOUT_LLD_IS_LD, for consistency with CLANG_IS_CC. 902 90320170112: 904 The EM_MULTIQUEUE kernel configuration option is deprecated now that 905 the em(4) driver conforms to iflib specifications. 906 90720170109: 908 The igb(4), em(4) and lem(4) ethernet drivers are now implemented via 909 IFLIB. If you have a custom kernel configuration that excludes em(4) 910 but you use igb(4), you need to re-add em(4) to your custom 911 configuration. 912 91320161217: 914 Clang, llvm, lldb, compiler-rt and libc++ have been upgraded to 3.9.1. 915 Please see the 20141231 entry below for information about prerequisites 916 and upgrading, if you are not already using clang 3.5.0 or higher. 917 91820161124: 919 Clang, llvm, lldb, compiler-rt and libc++ have been upgraded to 3.9.0. 920 Please see the 20141231 entry below for information about prerequisites 921 and upgrading, if you are not already using clang 3.5.0 or higher. 922 92320161119: 924 The layout of the pmap structure has changed for powerpc to put the pmap 925 statistics at the front for all CPU variations. libkvm(3) and all tools 926 that link against it need to be recompiled. 927 92820161030: 929 isl(4) and cyapa(4) drivers now require a new driver, 930 chromebook_platform(4), to work properly on Chromebook-class hardware. 931 On other types of hardware the drivers may need to be configured using 932 device hints. Please see the corresponding manual pages for details. 933 93420161017: 935 The urtwn(4) driver was merged into rtwn(4) and now consists of 936 rtwn(4) main module + rtwn_usb(4) and rtwn_pci(4) bus-specific 937 parts. 938 Also, firmware for RTL8188CE was renamed due to possible name 939 conflict (rtwnrtl8192cU(B) -> rtwnrtl8192cE(B)) 940 94120161015: 942 GNU rcs has been removed from base. It is available as packages: 943 - rcs: Latest GPLv3 GNU rcs version. 944 - rcs57: Copy of the latest version of GNU rcs (GPLv2) before it was 945 removed from base. 946 94720161008: 948 Use of the cc_cdg, cc_chd, cc_hd, or cc_vegas congestion control 949 modules now requires that the kernel configuration contain the 950 TCP_HHOOK option. (This option is included in the GENERIC kernel.) 951 95220161003: 953 The WITHOUT_ELFCOPY_AS_OBJCOPY src.conf(5) knob has been retired. 954 ELF Tool Chain's elfcopy is always installed as /usr/bin/objcopy. 955 95620160924: 957 Relocatable object files with the extension of .So have been renamed 958 to use an extension of .pico instead. The purpose of this change is 959 to avoid a name clash with shared libraries on case-insensitive file 960 systems. On those file systems, foo.So is the same file as foo.so. 961 96220160918: 963 GNU rcs has been turned off by default. It can (temporarily) be built 964 again by adding WITH_RCS knob in src.conf. 965 Otherwise, GNU rcs is available from packages: 966 - rcs: Latest GPLv3 GNU rcs version. 967 - rcs57: Copy of the latest version of GNU rcs (GPLv2) from base. 968 96920160918: 970 The backup_uses_rcs functionality has been removed from rc.subr. 971 97220160908: 973 The queue(3) debugging macro, QUEUE_MACRO_DEBUG, has been split into 974 two separate components, QUEUE_MACRO_DEBUG_TRACE and 975 QUEUE_MACRO_DEBUG_TRASH. Define both for the original 976 QUEUE_MACRO_DEBUG behavior. 977 97820160824: 979 r304787 changed some ioctl interfaces between the iSCSI userspace 980 programs and the kernel. ctladm, ctld, iscsictl, and iscsid must be 981 rebuilt to work with new kernels. __FreeBSD_version has been bumped 982 to 1200005. 983 98420160818: 985 The UDP receive code has been updated to only treat incoming UDP 986 packets that were addressed to an L2 broadcast address as L3 987 broadcast packets. It is not expected that this will affect any 988 standards-conforming UDP application. The new behaviour can be 989 disabled by setting the sysctl net.inet.udp.require_l2_bcast to 990 0. 991 99220160818: 993 Remove the openbsd_poll system call. 994 __FreeBSD_version has been bumped because of this. 995 99620160708: 997 The stable/11 branch has been created from head@r302406. 998 99920160622: 1000 The libc stub for the pipe(2) system call has been replaced with 1001 a wrapper that calls the pipe2(2) system call and the pipe(2) 1002 system call is now only implemented by the kernels that include 1003 "options COMPAT_FREEBSD10" in their config file (this is the 1004 default). Users should ensure that this option is enabled in 1005 their kernel or upgrade userspace to r302092 before upgrading their 1006 kernel. 1007 100820160527: 1009 CAM will now strip leading spaces from SCSI disks' serial numbers. 1010 This will affect users who create UFS filesystems on SCSI disks using 1011 those disk's diskid device nodes. For example, if /etc/fstab 1012 previously contained a line like 1013 "/dev/diskid/DISK-%20%20%20%20%20%20%20ABCDEFG0123456", you should 1014 change it to "/dev/diskid/DISK-ABCDEFG0123456". Users of geom 1015 transforms like gmirror may also be affected. ZFS users should 1016 generally be fine. 1017 101820160523: 1019 The bitstring(3) API has been updated with new functionality and 1020 improved performance. But it is binary-incompatible with the old API. 1021 Objects built with the new headers may not be linked against objects 1022 built with the old headers. 1023 102420160520: 1025 The brk and sbrk functions have been removed from libc on arm64. 1026 Binutils from ports has been updated to not link to these 1027 functions and should be updated to the latest version before 1028 installing a new libc. 1029 103020160517: 1031 The armv6 port now defaults to hard float ABI. Limited support 1032 for running both hardfloat and soft float on the same system 1033 is available using the libraries installed with -DWITH_LIBSOFT. 1034 This has only been tested as an upgrade path for installworld 1035 and packages may fail or need manual intervention to run. New 1036 packages will be needed. 1037 1038 To update an existing self-hosted armv6hf system, you must add 1039 TARGET_ARCH=armv6 on the make command line for both the build 1040 and the install steps. 1041 104220160510: 1043 Kernel modules compiled outside of a kernel build now default to 1044 installing to /boot/modules instead of /boot/kernel. Many kernel 1045 modules built this way (such as those in ports) already overrode 1046 KMODDIR explicitly to install into /boot/modules. However, 1047 manually building and installing a module from /sys/modules will 1048 now install to /boot/modules instead of /boot/kernel. 1049 105020160414: 1051 The CAM I/O scheduler has been committed to the kernel. There should be 1052 no user visible impact. This does enable NCQ Trim on ada SSDs. While the 1053 list of known rogues that claim support for this but actually corrupt 1054 data is believed to be complete, be on the lookout for data 1055 corruption. The known rogue list is believed to be complete: 1056 1057 o Crucial MX100, M550 drives with MU01 firmware. 1058 o Micron M510 and M550 drives with MU01 firmware. 1059 o Micron M500 prior to MU07 firmware 1060 o Samsung 830, 840, and 850 all firmwares 1061 o FCCT M500 all firmwares 1062 1063 Crucial has firmware http://www.crucial.com/usa/en/support-ssd-firmware 1064 with working NCQ TRIM. For Micron branded drives, see your sales rep for 1065 updated firmware. Black listed drives will work correctly because these 1066 drives work correctly so long as no NCQ TRIMs are sent to them. Given 1067 this list is the same as found in Linux, it's believed there are no 1068 other rogues in the market place. All other models from the above 1069 vendors work. 1070 1071 To be safe, if you are at all concerned, you can quirk each of your 1072 drives to prevent NCQ from being sent by setting: 1073 kern.cam.ada.X.quirks="0x2" 1074 in loader.conf. If the drive requires the 4k sector quirk, set the 1075 quirks entry to 0x3. 1076 107720160330: 1078 The FAST_DEPEND build option has been removed and its functionality is 1079 now the one true way. The old mkdep(1) style of 'make depend' has 1080 been removed. See 20160311 for further details. 1081 108220160317: 1083 Resource range types have grown from unsigned long to uintmax_t. All 1084 drivers, and anything using libdevinfo, need to be recompiled. 1085 108620160311: 1087 WITH_FAST_DEPEND is now enabled by default for in-tree and out-of-tree 1088 builds. It no longer runs mkdep(1) during 'make depend', and the 1089 'make depend' stage can safely be skipped now as it is auto ran 1090 when building 'make all' and will generate all SRCS and DPSRCS before 1091 building anything else. Dependencies are gathered at compile time with 1092 -MF flags kept in separate .depend files per object file. Users should 1093 run 'make cleandepend' once if using -DNO_CLEAN to clean out older 1094 stale .depend files. 1095 109620160306: 1097 On amd64, clang 3.8.0 can now insert sections of type AMD64_UNWIND into 1098 kernel modules. Therefore, if you load any kernel modules at boot time, 1099 please install the boot loaders after you install the kernel, but before 1100 rebooting, e.g.: 1101 1102 make buildworld 1103 make buildkernel KERNCONF=YOUR_KERNEL_HERE 1104 make installkernel KERNCONF=YOUR_KERNEL_HERE 1105 make -C sys/boot install 1106 <reboot in single user> 1107 1108 Then follow the usual steps, described in the General Notes section, 1109 below. 1110 111120160305: 1112 Clang, llvm, lldb and compiler-rt have been upgraded to 3.8.0. Please 1113 see the 20141231 entry below for information about prerequisites and 1114 upgrading, if you are not already using clang 3.5.0 or higher. 1115 111620160301: 1117 The AIO subsystem is now a standard part of the kernel. The 1118 VFS_AIO kernel option and aio.ko kernel module have been removed. 1119 Due to stability concerns, asynchronous I/O requests are only 1120 permitted on sockets and raw disks by default. To enable 1121 asynchronous I/O requests on all file types, set the 1122 vfs.aio.enable_unsafe sysctl to a non-zero value. 1123 112420160226: 1125 The ELF object manipulation tool objcopy is now provided by the 1126 ELF Tool Chain project rather than by GNU binutils. It should be a 1127 drop-in replacement, with the addition of arm64 support. The 1128 (temporary) src.conf knob WITHOUT_ELFCOPY_AS_OBJCOPY knob may be set 1129 to obtain the GNU version if necessary. 1130 113120160129: 1132 Building ZFS pools on top of zvols is prohibited by default. That 1133 feature has never worked safely; it's always been prone to deadlocks. 1134 Using a zvol as the backing store for a VM guest's virtual disk will 1135 still work, even if the guest is using ZFS. Legacy behavior can be 1136 restored by setting vfs.zfs.vol.recursive=1. 1137 113820160119: 1139 The NONE and HPN patches has been removed from OpenSSH. They are 1140 still available in the security/openssh-portable port. 1141 114220160113: 1143 With the addition of ypldap(8), a new _ypldap user is now required 1144 during installworld. "mergemaster -p" can be used to add the user 1145 prior to installworld, as documented in the handbook. 1146 114720151216: 1148 The tftp loader (pxeboot) now uses the option root-path directive. As a 1149 consequence it no longer looks for a pxeboot.4th file on the tftp 1150 server. Instead it uses the regular /boot infrastructure as with the 1151 other loaders. 1152 115320151211: 1154 The code to start recording plug and play data into the modules has 1155 been committed. While the old tools will properly build a new kernel, 1156 a number of warnings about "unknown metadata record 4" will be produced 1157 for an older kldxref. To avoid such warnings, make sure to rebuild 1158 the kernel toolchain (or world). Make sure that you have r292078 or 1159 later when trying to build 292077 or later before rebuilding. 1160 116120151207: 1162 Debug data files are now built by default with 'make buildworld' and 1163 installed with 'make installworld'. This facilitates debugging but 1164 requires more disk space both during the build and for the installed 1165 world. Debug files may be disabled by setting WITHOUT_DEBUG_FILES=yes 1166 in src.conf(5). 1167 116820151130: 1169 r291527 changed the internal interface between the nfsd.ko and 1170 nfscommon.ko modules. As such, they must both be upgraded to-gether. 1171 __FreeBSD_version has been bumped because of this. 1172 117320151108: 1174 Add support for unicode collation strings leads to a change of 1175 order of files listed by ls(1) for example. To get back to the old 1176 behaviour, set LC_COLLATE environment variable to "C". 1177 1178 Databases administrators will need to reindex their databases given 1179 collation results will be different. 1180 1181 Due to a bug in install(1) it is recommended to remove the ancient 1182 locales before running make installworld. 1183 1184 rm -rf /usr/share/locale/* 1185 118620151030: 1187 The OpenSSL has been upgraded to 1.0.2d. Any binaries requiring 1188 libcrypto.so.7 or libssl.so.7 must be recompiled. 1189 119020151020: 1191 Qlogic 24xx/25xx firmware images were updated from 5.5.0 to 7.3.0. 1192 Kernel modules isp_2400_multi and isp_2500_multi were removed and 1193 should be replaced with isp_2400 and isp_2500 modules respectively. 1194 119520151017: 1196 The build previously allowed using 'make -n' to not recurse into 1197 sub-directories while showing what commands would be executed, and 1198 'make -n -n' to recursively show commands. Now 'make -n' will recurse 1199 and 'make -N' will not. 1200 120120151012: 1202 If you specify SENDMAIL_MC or SENDMAIL_CF in make.conf, mergemaster 1203 and etcupdate will now use this file. A custom sendmail.cf is now 1204 updated via this mechanism rather than via installworld. If you had 1205 excluded sendmail.cf in mergemaster.rc or etcupdate.conf, you may 1206 want to remove the exclusion or change it to "always install". 1207 /etc/mail/sendmail.cf is now managed the same way regardless of 1208 whether SENDMAIL_MC/SENDMAIL_CF is used. If you are not using 1209 SENDMAIL_MC/SENDMAIL_CF there should be no change in behavior. 1210 121120151011: 1212 Compatibility shims for legacy ATA device names have been removed. 1213 It includes ATA_STATIC_ID kernel option, kern.cam.ada.legacy_aliases 1214 and kern.geom.raid.legacy_aliases loader tunables, kern.devalias.* 1215 environment variables, /dev/ad* and /dev/ar* symbolic links. 1216 121720151006: 1218 Clang, llvm, lldb, compiler-rt and libc++ have been upgraded to 3.7.0. 1219 Please see the 20141231 entry below for information about prerequisites 1220 and upgrading, if you are not already using clang 3.5.0 or higher. 1221 122220150924: 1223 Kernel debug files have been moved to /usr/lib/debug/boot/kernel/, 1224 and renamed from .symbols to .debug. This reduces the size requirements 1225 on the boot partition or file system and provides consistency with 1226 userland debug files. 1227 1228 When using the supported kernel installation method the 1229 /usr/lib/debug/boot/kernel directory will be renamed (to kernel.old) 1230 as is done with /boot/kernel. 1231 1232 Developers wishing to maintain the historical behavior of installing 1233 debug files in /boot/kernel/ can set KERN_DEBUGDIR="" in src.conf(5). 1234 123520150827: 1236 The wireless drivers had undergone changes that remove the 'parent 1237 interface' from the ifconfig -l output. The rc.d network scripts 1238 used to check presence of a parent interface in the list, so old 1239 scripts would fail to start wireless networking. Thus, etcupdate(3) 1240 or mergemaster(8) run is required after kernel update, to update your 1241 rc.d scripts in /etc. 1242 124320150827: 1244 pf no longer supports 'scrub fragment crop' or 'scrub fragment drop-ovl' 1245 These configurations are now automatically interpreted as 1246 'scrub fragment reassemble'. 1247 124820150817: 1249 Kernel-loadable modules for the random(4) device are back. To use 1250 them, the kernel must have 1251 1252 device random 1253 options RANDOM_LOADABLE 1254 1255 kldload(8) can then be used to load random_fortuna.ko 1256 or random_yarrow.ko. Please note that due to the indirect 1257 function calls that the loadable modules need to provide, 1258 the build-in variants will be slightly more efficient. 1259 1260 The random(4) kernel option RANDOM_DUMMY has been retired due to 1261 unpopularity. It was not all that useful anyway. 1262 126320150813: 1264 The WITHOUT_ELFTOOLCHAIN_TOOLS src.conf(5) knob has been retired. 1265 Control over building the ELF Tool Chain tools is now provided by 1266 the WITHOUT_TOOLCHAIN knob. 1267 126820150810: 1269 The polarity of Pulse Per Second (PPS) capture events with the 1270 uart(4) driver has been corrected. Prior to this change the PPS 1271 "assert" event corresponded to the trailing edge of a positive PPS 1272 pulse and the "clear" event was the leading edge of the next pulse. 1273 1274 As the width of a PPS pulse in a typical GPS receiver is on the 1275 order of 1 millisecond, most users will not notice any significant 1276 difference with this change. 1277 1278 Anyone who has compensated for the historical polarity reversal by 1279 configuring a negative offset equal to the pulse width will need to 1280 remove that workaround. 1281 128220150809: 1283 The default group assigned to /dev/dri entries has been changed 1284 from 'wheel' to 'video' with the id of '44'. If you want to have 1285 access to the dri devices please add yourself to the video group 1286 with: 1287 1288 # pw groupmod video -m $USER 1289 129020150806: 1291 The menu.rc and loader.rc files will now be replaced during 1292 upgrades. Please migrate local changes to menu.rc.local and 1293 loader.rc.local instead. 1294 129520150805: 1296 GNU Binutils versions of addr2line, c++filt, nm, readelf, size, 1297 strings and strip have been removed. The src.conf(5) knob 1298 WITHOUT_ELFTOOLCHAIN_TOOLS no longer provides the binutils tools. 1299 130020150728: 1301 As ZFS requires more kernel stack pages than is the default on some 1302 architectures e.g. i386, it now warns if KSTACK_PAGES is less than 1303 ZFS_MIN_KSTACK_PAGES (which is 4 at the time of writing). 1304 1305 Please consider using 'options KSTACK_PAGES=X' where X is greater 1306 than or equal to ZFS_MIN_KSTACK_PAGES i.e. 4 in such configurations. 1307 130820150706: 1309 sendmail has been updated to 8.15.2. Starting with FreeBSD 11.0 1310 and sendmail 8.15, sendmail uses uncompressed IPv6 addresses by 1311 default, i.e., they will not contain "::". For example, instead 1312 of ::1, it will be 0:0:0:0:0:0:0:1. This permits a zero subnet 1313 to have a more specific match, such as different map entries for 1314 IPv6:0:0 vs IPv6:0. This change requires that configuration 1315 data (including maps, files, classes, custom ruleset, etc.) must 1316 use the same format, so make certain such configuration data is 1317 upgrading. As a very simple check search for patterns like 1318 'IPv6:[0-9a-fA-F:]*::' and 'IPv6::'. To return to the old 1319 behavior, set the m4 option confUSE_COMPRESSED_IPV6_ADDRESSES or 1320 the cf option UseCompressedIPv6Addresses. 1321 132220150630: 1323 The default kernel entropy-processing algorithm is now 1324 Fortuna, replacing Yarrow. 1325 1326 Assuming you have 'device random' in your kernel config 1327 file, the configurations allow a kernel option to override 1328 this default. You may choose *ONE* of: 1329 1330 options RANDOM_YARROW # Legacy /dev/random algorithm. 1331 options RANDOM_DUMMY # Blocking-only driver. 1332 1333 If you have neither, you get Fortuna. For most people, 1334 read no further, Fortuna will give a /dev/random that works 1335 like it always used to, and the difference will be irrelevant. 1336 1337 If you remove 'device random', you get *NO* kernel-processed 1338 entropy at all. This may be acceptable to folks building 1339 embedded systems, but has complications. Carry on reading, 1340 and it is assumed you know what you need. 1341 1342 *PLEASE* read random(4) and random(9) if you are in the 1343 habit of tweaking kernel configs, and/or if you are a member 1344 of the embedded community, wanting specific and not-usual 1345 behaviour from your security subsystems. 1346 1347 NOTE!! If you use RANDOM_DUMMY and/or have no 'device 1348 random', you will NOT have a functioning /dev/random, and 1349 many cryptographic features will not work, including SSH. 1350 You may also find strange behaviour from the random(3) set 1351 of library functions, in particular sranddev(3), srandomdev(3) 1352 and arc4random(3). The reason for this is that the KERN_ARND 1353 sysctl only returns entropy if it thinks it has some to 1354 share, and with RANDOM_DUMMY or no 'device random' this 1355 will never happen. 1356 135720150623: 1358 An additional fix for the issue described in the 20150614 sendmail 1359 entry below has been committed in revision 284717. 1360 136120150616: 1362 FreeBSD's old make (fmake) has been removed from the system. It is 1363 available as the devel/fmake port or via pkg install fmake. 1364 136520150615: 1366 The fix for the issue described in the 20150614 sendmail entry 1367 below has been committed in revision 284436. The work 1368 around described in that entry is no longer needed unless the 1369 default setting is overridden by a confDH_PARAMETERS configuration 1370 setting of '5' or pointing to a 512 bit DH parameter file. 1371 137220150614: 1373 ALLOW_DEPRECATED_ATF_TOOLS/ATFFILE support has been removed from 1374 atf.test.mk (included from bsd.test.mk). Please upgrade devel/atf 1375 and devel/kyua to version 0.20+ and adjust any calling code to work 1376 with Kyuafile and kyua. 1377 137820150614: 1379 The import of openssl to address the FreeBSD-SA-15:10.openssl 1380 security advisory includes a change which rejects handshakes 1381 with DH parameters below 768 bits. sendmail releases prior 1382 to 8.15.2 (not yet released), defaulted to a 512 bit 1383 DH parameter setting for client connections. To work around 1384 this interoperability, sendmail can be configured to use a 1385 2048 bit DH parameter by: 1386 1387 1. Edit /etc/mail/`hostname`.mc 1388 2. If a setting for confDH_PARAMETERS does not exist or 1389 exists and is set to a string beginning with '5', 1390 replace it with '2'. 1391 3. If a setting for confDH_PARAMETERS exists and is set to 1392 a file path, create a new file with: 1393 openssl dhparam -out /path/to/file 2048 1394 4. Rebuild the .cf file: 1395 cd /etc/mail/; make; make install 1396 5. Restart sendmail: 1397 cd /etc/mail/; make restart 1398 1399 A sendmail patch is coming, at which time this file will be 1400 updated. 1401 140220150604: 1403 Generation of legacy formatted entries have been disabled by default 1404 in pwd_mkdb(8), as all base system consumers of the legacy formatted 1405 entries were converted to use the new format by default when the new, 1406 machine independent format have been added and supported since FreeBSD 1407 5.x. 1408 1409 Please see the pwd_mkdb(8) manual page for further details. 1410 141120150525: 1412 Clang and llvm have been upgraded to 3.6.1 release. Please see the 1413 20141231 entry below for information about prerequisites and upgrading, 1414 if you are not already using 3.5.0 or higher. 1415 141620150521: 1417 TI platform code switched to using vendor DTS files and this update 1418 may break existing systems running on Beaglebone, Beaglebone Black, 1419 and Pandaboard: 1420 1421 - dtb files should be regenerated/reinstalled. Filenames are the 1422 same but content is different now 1423 - GPIO addressing was changed, now each GPIO bank (32 pins per bank) 1424 has its own /dev/gpiocX device, e.g. pin 121 on /dev/gpioc0 in old 1425 addressing scheme is now pin 25 on /dev/gpioc3. 1426 - Pandaboard: /etc/ttys should be updated, serial console device is 1427 now /dev/ttyu2, not /dev/ttyu0 1428 142920150501: 1430 soelim(1) from gnu/usr.bin/groff has been replaced by usr.bin/soelim. 1431 If you need the GNU extension from groff soelim(1), install groff 1432 from package: pkg install groff, or via ports: textproc/groff. 1433 143420150423: 1435 chmod, chflags, chown and chgrp now affect symlinks in -R mode as 1436 defined in symlink(7); previously symlinks were silently ignored. 1437 143820150415: 1439 The const qualifier has been removed from iconv(3) to comply with 1440 POSIX. The ports tree is aware of this from r384038 onwards. 1441 144220150416: 1443 Libraries specified by LIBADD in Makefiles must have a corresponding 1444 DPADD_<lib> variable to ensure correct dependencies. This is now 1445 enforced in src.libnames.mk. 1446 144720150324: 1448 From legacy ata(4) driver was removed support for SATA controllers 1449 supported by more functional drivers ahci(4), siis(4) and mvs(4). 1450 Kernel modules ataahci and ataadaptec were removed completely, 1451 replaced by ahci and mvs modules respectively. 1452 145320150315: 1454 Clang, llvm and lldb have been upgraded to 3.6.0 release. Please see 1455 the 20141231 entry below for information about prerequisites and 1456 upgrading, if you are not already using 3.5.0 or higher. 1457 145820150307: 1459 The 32-bit PowerPC kernel has been changed to a position-independent 1460 executable. This can only be booted with a version of loader(8) 1461 newer than January 31, 2015, so make sure to update both world and 1462 kernel before rebooting. 1463 146420150217: 1465 If you are running a -CURRENT kernel since r273872 (Oct 30th, 2014), 1466 but before r278950, the RNG was not seeded properly. Immediately 1467 upgrade the kernel to r278950 or later and regenerate any keys (e.g. 1468 ssh keys or openssl keys) that were generated w/ a kernel from that 1469 range. This does not affect programs that directly used /dev/random 1470 or /dev/urandom. All userland uses of arc4random(3) are affected. 1471 147220150210: 1473 The autofs(4) ABI was changed in order to restore binary compatibility 1474 with 10.1-RELEASE. The automountd(8) daemon needs to be rebuilt to work 1475 with the new kernel. 1476 147720150131: 1478 The powerpc64 kernel has been changed to a position-independent 1479 executable. This can only be booted with a new version of loader(8), 1480 so make sure to update both world and kernel before rebooting. 1481 148220150118: 1483 Clang and llvm have been upgraded to 3.5.1 release. This is a bugfix 1484 only release, no new features have been added. Please see the 20141231 1485 entry below for information about prerequisites and upgrading, if you 1486 are not already using 3.5.0. 1487 148820150107: 1489 ELF tools addr2line, elfcopy (strip), nm, size, and strings are now 1490 taken from the ELF Tool Chain project rather than GNU binutils. They 1491 should be drop-in replacements, with the addition of arm64 support. 1492 The WITHOUT_ELFTOOLCHAIN_TOOLS= knob may be used to obtain the 1493 binutils tools, if necessary. See 20150805 for updated information. 1494 149520150105: 1496 The default Unbound configuration now enables remote control 1497 using a local socket. Users who have already enabled the 1498 local_unbound service should regenerate their configuration 1499 by running "service local_unbound setup" as root. 1500 150120150102: 1502 The GNU texinfo and GNU info pages have been removed. 1503 To be able to view GNU info pages please install texinfo from ports. 1504 150520141231: 1506 Clang, llvm and lldb have been upgraded to 3.5.0 release. 1507 1508 As of this release, a prerequisite for building clang, llvm and lldb is 1509 a C++11 capable compiler and C++11 standard library. This means that to 1510 be able to successfully build the cross-tools stage of buildworld, with 1511 clang as the bootstrap compiler, your system compiler or cross compiler 1512 should either be clang 3.3 or later, or gcc 4.8 or later, and your 1513 system C++ library should be libc++, or libdstdc++ from gcc 4.8 or 1514 later. 1515 1516 On any standard FreeBSD 10.x or 11.x installation, where clang and 1517 libc++ are on by default (that is, on x86 or arm), this should work out 1518 of the box. 1519 1520 On 9.x installations where clang is enabled by default, e.g. on x86 and 1521 powerpc, libc++ will not be enabled by default, so libc++ should be 1522 built (with clang) and installed first. If both clang and libc++ are 1523 missing, build clang first, then use it to build libc++. 1524 1525 On 8.x and earlier installations, upgrade to 9.x first, and then follow 1526 the instructions for 9.x above. 1527 1528 Sparc64 and mips users are unaffected, as they still use gcc 4.2.1 by 1529 default, and do not build clang. 1530 1531 Many embedded systems are resource constrained, and will not be able to 1532 build clang in a reasonable time, or in some cases at all. In those 1533 cases, cross building bootable systems on amd64 is a workaround. 1534 1535 This new version of clang introduces a number of new warnings, of which 1536 the following are most likely to appear: 1537 1538 -Wabsolute-value 1539 1540 This warns in two cases, for both C and C++: 1541 * When the code is trying to take the absolute value of an unsigned 1542 quantity, which is effectively a no-op, and almost never what was 1543 intended. The code should be fixed, if at all possible. If you are 1544 sure that the unsigned quantity can be safely cast to signed, without 1545 loss of information or undefined behavior, you can add an explicit 1546 cast, or disable the warning. 1547 1548 * When the code is trying to take an absolute value, but the called 1549 abs() variant is for the wrong type, which can lead to truncation. 1550 If you want to disable the warning instead of fixing the code, please 1551 make sure that truncation will not occur, or it might lead to unwanted 1552 side-effects. 1553 1554 -Wtautological-undefined-compare and 1555 -Wundefined-bool-conversion 1556 1557 These warn when C++ code is trying to compare 'this' against NULL, while 1558 'this' should never be NULL in well-defined C++ code. However, there is 1559 some legacy (pre C++11) code out there, which actively abuses this 1560 feature, which was less strictly defined in previous C++ versions. 1561 1562 Squid and openjdk do this, for example. The warning can be turned off 1563 for C++98 and earlier, but compiling the code in C++11 mode might result 1564 in unexpected behavior; for example, the parts of the program that are 1565 unreachable could be optimized away. 1566 156720141222: 1568 The old NFS client and server (kernel options NFSCLIENT, NFSSERVER) 1569 kernel sources have been removed. The .h files remain, since some 1570 utilities include them. This will need to be fixed later. 1571 If "mount -t oldnfs ..." is attempted, it will fail. 1572 If the "-o" option on mountd(8), nfsd(8) or nfsstat(1) is used, 1573 the utilities will report errors. 1574 157520141121: 1576 The handling of LOCAL_LIB_DIRS has been altered to skip addition of 1577 directories to top level SUBDIR variable when their parent 1578 directory is included in LOCAL_DIRS. Users with build systems with 1579 such hierarchies and without SUBDIR entries in the parent 1580 directory Makefiles should add them or add the directories to 1581 LOCAL_DIRS. 1582 158320141109: 1584 faith(4) and faithd(8) have been removed from the base system. Faith 1585 has been obsolete for a very long time. 1586 158720141104: 1588 vt(4), the new console driver, is enabled by default. It brings 1589 support for Unicode and double-width characters, as well as 1590 support for UEFI and integration with the KMS kernel video 1591 drivers. 1592 1593 You may need to update your console settings in /etc/rc.conf, 1594 most probably the keymap. During boot, /etc/rc.d/syscons will 1595 indicate what you need to do. 1596 1597 vt(4) still has issues and lacks some features compared to 1598 syscons(4). See the wiki for up-to-date information: 1599 https://wiki.freebsd.org/Newcons 1600 1601 If you want to keep using syscons(4), you can do so by adding 1602 the following line to /boot/loader.conf: 1603 kern.vty=sc 1604 160520141102: 1606 pjdfstest has been integrated into kyua as an opt-in test suite. 1607 Please see share/doc/pjdfstest/README for more details on how to 1608 execute it. 1609 161020141009: 1611 gperf has been removed from the base system for architectures 1612 that use clang. Ports that require gperf will obtain it from the 1613 devel/gperf port. 1614 161520140923: 1616 pjdfstest has been moved from tools/regression/pjdfstest to 1617 contrib/pjdfstest . 1618 161920140922: 1620 At svn r271982, The default linux compat kernel ABI has been adjusted 1621 to 2.6.18 in support of the linux-c6 compat ports infrastructure 1622 update. If you wish to continue using the linux-f10 compat ports, 1623 add compat.linux.osrelease=2.6.16 to your local sysctl.conf. Users are 1624 encouraged to update their linux-compat packages to linux-c6 during 1625 their next update cycle. 1626 162720140729: 1628 The ofwfb driver, used to provide a graphics console on PowerPC when 1629 using vt(4), no longer allows mmap() of all physical memory. This 1630 will prevent Xorg on PowerPC with some ATI graphics cards from 1631 initializing properly unless x11-servers/xorg-server is updated to 1632 1.12.4_8 or newer. 1633 163420140723: 1635 The xdev targets have been converted to using TARGET and 1636 TARGET_ARCH instead of XDEV and XDEV_ARCH. 1637 163820140719: 1639 The default unbound configuration has been modified to address 1640 issues with reverse lookups on networks that use private 1641 address ranges. If you use the local_unbound service, run 1642 "service local_unbound setup" as root to regenerate your 1643 configuration, then "service local_unbound reload" to load the 1644 new configuration. 1645 164620140709: 1647 The GNU texinfo and GNU info pages are not built and installed 1648 anymore, WITH_INFO knob has been added to allow to built and install 1649 them again. 1650 UPDATE: see 20150102 entry on texinfo's removal 1651 165220140708: 1653 The GNU readline library is now an INTERNALLIB - that is, it is 1654 statically linked into consumers (GDB and variants) in the base 1655 system, and the shared library is no longer installed. The 1656 devel/readline port is available for third party software that 1657 requires readline. 1658 165920140702: 1660 The Itanium architecture (ia64) has been removed from the list of 1661 known architectures. This is the first step in the removal of the 1662 architecture. 1663 166420140701: 1665 Commit r268115 has added NFSv4.1 server support, merged from 1666 projects/nfsv4.1-server. Since this includes changes to the 1667 internal interfaces between the NFS related modules, a full 1668 build of the kernel and modules will be necessary. 1669 __FreeBSD_version has been bumped. 1670 167120140629: 1672 The WITHOUT_VT_SUPPORT kernel config knob has been renamed 1673 WITHOUT_VT. (The other _SUPPORT knobs have a consistent meaning 1674 which differs from the behaviour controlled by this knob.) 1675 167620140619: 1677 Maximal length of the serial number in CTL was increased from 16 to 1678 64 chars, that breaks ABI. All CTL-related tools, such as ctladm 1679 and ctld, need to be rebuilt to work with a new kernel. 1680 168120140606: 1682 The libatf-c and libatf-c++ major versions were downgraded to 0 and 1683 1 respectively to match the upstream numbers. They were out of 1684 sync because, when they were originally added to FreeBSD, the 1685 upstream versions were not respected. These libraries are private 1686 and not yet built by default, so renumbering them should be a 1687 non-issue. However, unclean source trees will yield broken test 1688 programs once the operator executes "make delete-old-libs" after a 1689 "make installworld". 1690 1691 Additionally, the atf-sh binary was made private by moving it into 1692 /usr/libexec/. Already-built shell test programs will keep the 1693 path to the old binary so they will break after "make delete-old" 1694 is run. 1695 1696 If you are using WITH_TESTS=yes (not the default), wipe the object 1697 tree and rebuild from scratch to prevent spurious test failures. 1698 This is only needed once: the misnumbered libraries and misplaced 1699 binaries have been added to OptionalObsoleteFiles.inc so they will 1700 be removed during a clean upgrade. 1701 170220140512: 1703 Clang and llvm have been upgraded to 3.4.1 release. 1704 170520140508: 1706 We bogusly installed src.opts.mk in /usr/share/mk. This file should 1707 be removed to avoid issues in the future (and has been added to 1708 ObsoleteFiles.inc). 1709 171020140505: 1711 /etc/src.conf now affects only builds of the FreeBSD src tree. In the 1712 past, it affected all builds that used the bsd.*.mk files. The old 1713 behavior was a bug, but people may have relied upon it. To get this 1714 behavior back, you can .include /etc/src.conf from /etc/make.conf 1715 (which is still global and isn't changed). This also changes the 1716 behavior of incremental builds inside the tree of individual 1717 directories. Set MAKESYSPATH to ".../share/mk" to do that. 1718 Although this has survived make universe and some upgrade scenarios, 1719 other upgrade scenarios may have broken. At least one form of 1720 temporary breakage was fixed with MAKESYSPATH settings for buildworld 1721 as well... In cases where MAKESYSPATH isn't working with this 1722 setting, you'll need to set it to the full path to your tree. 1723 1724 One side effect of all this cleaning up is that bsd.compiler.mk 1725 is no longer implicitly included by bsd.own.mk. If you wish to 1726 use COMPILER_TYPE, you must now explicitly include bsd.compiler.mk 1727 as well. 1728 172920140430: 1730 The lindev device has been removed since /dev/full has been made a 1731 standard device. __FreeBSD_version has been bumped. 1732 173320140424: 1734 The knob WITHOUT_VI was added to the base system, which controls 1735 building ex(1), vi(1), etc. Older releases of FreeBSD required ex(1) 1736 in order to reorder files share/termcap and didn't build ex(1) as a 1737 build tool, so building/installing with WITH_VI is highly advised for 1738 build hosts for older releases. 1739 1740 This issue has been fixed in stable/9 and stable/10 in r277022 and 1741 r276991, respectively. 1742 174320140418: 1744 The YES_HESIOD knob has been removed. It has been obsolete for 1745 a decade. Please move to using WITH_HESIOD instead or your builds 1746 will silently lack HESIOD. 1747 174820140405: 1749 The uart(4) driver has been changed with respect to its handling 1750 of the low-level console. Previously the uart(4) driver prevented 1751 any process from changing the baudrate or the CLOCAL and HUPCL 1752 control flags. By removing the restrictions, operators can make 1753 changes to the serial console port without having to reboot. 1754 However, when getty(8) is started on the serial device that is 1755 associated with the low-level console, a misconfigured terminal 1756 line in /etc/ttys will now have a real impact. 1757 Before upgrading the kernel, make sure that /etc/ttys has the 1758 serial console device configured as 3wire without baudrate to 1759 preserve the previous behaviour. E.g: 1760 ttyu0 "/usr/libexec/getty 3wire" vt100 on secure 1761 176220140306: 1763 Support for libwrap (TCP wrappers) in rpcbind was disabled by default 1764 to improve performance. To re-enable it, if needed, run rpcbind 1765 with command line option -W. 1766 176720140226: 1768 Switched back to the GPL dtc compiler due to updates in the upstream 1769 dts files not being supported by the BSDL dtc compiler. You will need 1770 to rebuild your kernel toolchain to pick up the new compiler. Core dumps 1771 may result while building dtb files during a kernel build if you fail 1772 to do so. Set WITHOUT_GPL_DTC if you require the BSDL compiler. 1773 177420140216: 1775 Clang and llvm have been upgraded to 3.4 release. 1776 177720140216: 1778 The nve(4) driver has been removed. Please use the nfe(4) driver 1779 for NVIDIA nForce MCP Ethernet adapters instead. 1780 178120140212: 1782 An ABI incompatibility crept into the libc++ 3.4 import in r261283. 1783 This could cause certain C++ applications using shared libraries built 1784 against the previous version of libc++ to crash. The incompatibility 1785 has now been fixed, but any C++ applications or shared libraries built 1786 between r261283 and r261801 should be recompiled. 1787 178820140204: 1789 OpenSSH will now ignore errors caused by kernel lacking of Capsicum 1790 capability mode support. Please note that enabling the feature in 1791 kernel is still highly recommended. 1792 179320140131: 1794 OpenSSH is now built with sandbox support, and will use sandbox as 1795 the default privilege separation method. This requires Capsicum 1796 capability mode support in kernel. 1797 179820140128: 1799 The libelf and libdwarf libraries have been updated to newer 1800 versions from upstream. Shared library version numbers for 1801 these two libraries were bumped. Any ports or binaries 1802 requiring these two libraries should be recompiled. 1803 __FreeBSD_version is bumped to 1100006. 1804 180520140110: 1806 If a Makefile in a tests/ directory was auto-generating a Kyuafile 1807 instead of providing an explicit one, this would prevent such 1808 Makefile from providing its own Kyuafile in the future during 1809 NO_CLEAN builds. This has been fixed in the Makefiles but manual 1810 intervention is needed to clean an objdir if you use NO_CLEAN: 1811 # find /usr/obj -name Kyuafile | xargs rm -f 1812 181320131213: 1814 The behavior of gss_pseudo_random() for the krb5 mechanism 1815 has changed, for applications requesting a longer random string 1816 than produced by the underlying enctype's pseudo-random() function. 1817 In particular, the random string produced from a session key of 1818 enctype aes256-cts-hmac-sha1-96 or aes256-cts-hmac-sha1-96 will 1819 be different at the 17th octet and later, after this change. 1820 The counter used in the PRF+ construction is now encoded as a 1821 big-endian integer in accordance with RFC 4402. 1822 __FreeBSD_version is bumped to 1100004. 1823 182420131108: 1825 The WITHOUT_ATF build knob has been removed and its functionality 1826 has been subsumed into the more generic WITHOUT_TESTS. If you were 1827 using the former to disable the build of the ATF libraries, you 1828 should change your settings to use the latter. 1829 183020131025: 1831 The default version of mtree is nmtree which is obtained from 1832 NetBSD. The output is generally the same, but may vary 1833 slightly. If you found you need identical output adding 1834 "-F freebsd9" to the command line should do the trick. For the 1835 time being, the old mtree is available as fmtree. 1836 183720131014: 1838 libbsdyml has been renamed to libyaml and moved to /usr/lib/private. 1839 This will break ports-mgmt/pkg. Rebuild the port, or upgrade to pkg 1840 1.1.4_8 and verify bsdyml not linked in, before running "make 1841 delete-old-libs": 1842 # make -C /usr/ports/ports-mgmt/pkg build deinstall install clean 1843 or 1844 # pkg install pkg; ldd /usr/local/sbin/pkg | grep bsdyml 1845 184620131010: 1847 The stable/10 branch has been created in subversion from head 1848 revision r256279. 1849 1850COMMON ITEMS: 1851 1852 General Notes 1853 ------------- 1854 Avoid using make -j when upgrading. While generally safe, there are 1855 sometimes problems using -j to upgrade. If your upgrade fails with 1856 -j, please try again without -j. From time to time in the past there 1857 have been problems using -j with buildworld and/or installworld. This 1858 is especially true when upgrading between "distant" versions (eg one 1859 that cross a major release boundary or several minor releases, or when 1860 several months have passed on the -current branch). 1861 1862 Sometimes, obscure build problems are the result of environment 1863 poisoning. This can happen because the make utility reads its 1864 environment when searching for values for global variables. To run 1865 your build attempts in an "environmental clean room", prefix all make 1866 commands with 'env -i '. See the env(1) manual page for more details. 1867 1868 When upgrading from one major version to another it is generally best to 1869 upgrade to the latest code in the currently installed branch first, then 1870 do an upgrade to the new branch. This is the best-tested upgrade path, 1871 and has the highest probability of being successful. Please try this 1872 approach if you encounter problems with a major version upgrade. Since 1873 the stable 4.x branch point, one has generally been able to upgrade from 1874 anywhere in the most recent stable branch to head / current (or even the 1875 last couple of stable branches). See the top of this file when there's 1876 an exception. 1877 1878 When upgrading a live system, having a root shell around before 1879 installing anything can help undo problems. Not having a root shell 1880 around can lead to problems if pam has changed too much from your 1881 starting point to allow continued authentication after the upgrade. 1882 1883 This file should be read as a log of events. When a later event changes 1884 information of a prior event, the prior event should not be deleted. 1885 Instead, a pointer to the entry with the new information should be 1886 placed in the old entry. Readers of this file should also sanity check 1887 older entries before relying on them blindly. Authors of new entries 1888 should write them with this in mind. 1889 1890 ZFS notes 1891 --------- 1892 When upgrading the boot ZFS pool to a new version, always follow 1893 these two steps: 1894 1895 1.) recompile and reinstall the ZFS boot loader and boot block 1896 (this is part of "make buildworld" and "make installworld") 1897 1898 2.) update the ZFS boot block on your boot drive 1899 1900 The following example updates the ZFS boot block on the first 1901 partition (freebsd-boot) of a GPT partitioned drive ada0: 1902 "gpart bootcode -p /boot/gptzfsboot -i 1 ada0" 1903 1904 Non-boot pools do not need these updates. 1905 1906 To build a kernel 1907 ----------------- 1908 If you are updating from a prior version of FreeBSD (even one just 1909 a few days old), you should follow this procedure. It is the most 1910 failsafe as it uses a /usr/obj tree with a fresh mini-buildworld, 1911 1912 make kernel-toolchain 1913 make -DALWAYS_CHECK_MAKE buildkernel KERNCONF=YOUR_KERNEL_HERE 1914 make -DALWAYS_CHECK_MAKE installkernel KERNCONF=YOUR_KERNEL_HERE 1915 1916 To test a kernel once 1917 --------------------- 1918 If you just want to boot a kernel once (because you are not sure 1919 if it works, or if you want to boot a known bad kernel to provide 1920 debugging information) run 1921 make installkernel KERNCONF=YOUR_KERNEL_HERE KODIR=/boot/testkernel 1922 nextboot -k testkernel 1923 1924 To rebuild everything and install it on the current system. 1925 ----------------------------------------------------------- 1926 # Note: sometimes if you are running current you gotta do more than 1927 # is listed here if you are upgrading from a really old current. 1928 1929 <make sure you have good level 0 dumps> 1930 make buildworld 1931 make buildkernel KERNCONF=YOUR_KERNEL_HERE 1932 make installkernel KERNCONF=YOUR_KERNEL_HERE 1933 [1] 1934 <reboot in single user> [3] 1935 mergemaster -Fp [5] 1936 make installworld 1937 mergemaster -Fi [4] 1938 make delete-old [6] 1939 <reboot> 1940 1941 To cross-install current onto a separate partition 1942 -------------------------------------------------- 1943 # In this approach we use a separate partition to hold 1944 # current's root, 'usr', and 'var' directories. A partition 1945 # holding "/", "/usr" and "/var" should be about 2GB in 1946 # size. 1947 1948 <make sure you have good level 0 dumps> 1949 <boot into -stable> 1950 make buildworld 1951 make buildkernel KERNCONF=YOUR_KERNEL_HERE 1952 <maybe newfs current's root partition> 1953 <mount current's root partition on directory ${CURRENT_ROOT}> 1954 make installworld DESTDIR=${CURRENT_ROOT} -DDB_FROM_SRC 1955 make distribution DESTDIR=${CURRENT_ROOT} # if newfs'd 1956 make installkernel KERNCONF=YOUR_KERNEL_HERE DESTDIR=${CURRENT_ROOT} 1957 cp /etc/fstab ${CURRENT_ROOT}/etc/fstab # if newfs'd 1958 <edit ${CURRENT_ROOT}/etc/fstab to mount "/" from the correct partition> 1959 <reboot into current> 1960 <do a "native" rebuild/install as described in the previous section> 1961 <maybe install compatibility libraries from ports/misc/compat*> 1962 <reboot> 1963 1964 1965 To upgrade in-place from stable to current 1966 ---------------------------------------------- 1967 <make sure you have good level 0 dumps> 1968 make buildworld [9] 1969 make buildkernel KERNCONF=YOUR_KERNEL_HERE [8] 1970 make installkernel KERNCONF=YOUR_KERNEL_HERE 1971 [1] 1972 <reboot in single user> [3] 1973 mergemaster -Fp [5] 1974 make installworld 1975 mergemaster -Fi [4] 1976 make delete-old [6] 1977 <reboot> 1978 1979 Make sure that you've read the UPDATING file to understand the 1980 tweaks to various things you need. At this point in the life 1981 cycle of current, things change often and you are on your own 1982 to cope. The defaults can also change, so please read ALL of 1983 the UPDATING entries. 1984 1985 Also, if you are tracking -current, you must be subscribed to 1986 freebsd-current@freebsd.org. Make sure that before you update 1987 your sources that you have read and understood all the recent 1988 messages there. If in doubt, please track -stable which has 1989 much fewer pitfalls. 1990 1991 [1] If you have third party modules, such as vmware, you 1992 should disable them at this point so they don't crash your 1993 system on reboot. 1994 1995 [3] From the bootblocks, boot -s, and then do 1996 fsck -p 1997 mount -u / 1998 mount -a 1999 sh /etc/rc.d/zfs start # mount zfs filesystem, if needed 2000 cd src # full path to source 2001 adjkerntz -i # if CMOS is wall time 2002 Also, when doing a major release upgrade, it is required that 2003 you boot into single user mode to do the installworld. 2004 2005 [4] Note: This step is non-optional. Failure to do this step 2006 can result in a significant reduction in the functionality of the 2007 system. Attempting to do it by hand is not recommended and those 2008 that pursue this avenue should read this file carefully, as well 2009 as the archives of freebsd-current and freebsd-hackers mailing lists 2010 for potential gotchas. The -U option is also useful to consider. 2011 See mergemaster(8) for more information. 2012 2013 [5] Usually this step is a no-op. However, from time to time 2014 you may need to do this if you get unknown user in the following 2015 step. It never hurts to do it all the time. You may need to 2016 install a new mergemaster (cd src/usr.sbin/mergemaster && make 2017 install) after the buildworld before this step if you last updated 2018 from current before 20130425 or from -stable before 20130430. 2019 2020 [6] This only deletes old files and directories. Old libraries 2021 can be deleted by "make delete-old-libs", but you have to make 2022 sure that no program is using those libraries anymore. 2023 2024 [8] The new kernel must be able to run existing binaries used by an 2025 installworld. When upgrading across major versions, the new kernel's 2026 configuration must include the correct COMPAT_FREEBSD<n> option for 2027 existing binaries (e.g. COMPAT_FREEBSD11 to run 11.x binaries). Failure 2028 to do so may leave you with a system that is hard to boot to recover. A 2029 GENERIC kernel will include suitable compatibility options to run 2030 binaries from older branches. Note that the ability to run binaries 2031 from unsupported branches is not guaranteed. 2032 2033 Make sure that you merge any new devices from GENERIC since the 2034 last time you updated your kernel config file. Options also 2035 change over time, so you may need to adjust your custom kernels 2036 for these as well. 2037 2038 [9] If CPUTYPE is defined in your /etc/make.conf, make sure to use the 2039 "?=" instead of the "=" assignment operator, so that buildworld can 2040 override the CPUTYPE if it needs to. 2041 2042 MAKEOBJDIRPREFIX must be defined in an environment variable, and 2043 not on the command line, or in /etc/make.conf. buildworld will 2044 warn if it is improperly defined. 2045FORMAT: 2046 2047This file contains a list, in reverse chronological order, of major 2048breakages in tracking -current. It is not guaranteed to be a complete 2049list of such breakages, and only contains entries since September 23, 2011. 2050If you need to see UPDATING entries from before that date, you will need 2051to fetch an UPDATING file from an older FreeBSD release. 2052 2053Copyright information: 2054 2055Copyright 1998-2009 M.
