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: FreeBSD has switched from gcc to clang. If you have trouble bootstrapping 15from older versions of FreeBSD, try WITHOUT_CLANG and WITH_GCC to bootstrap to 16the tip of head, and then rebuild without this option. The bootstrap process 17from older version of current across the gcc/clang cutover is a bit fragile. 18 19NOTE TO PEOPLE WHO THINK THAT FreeBSD 13.x IS SLOW: 20 FreeBSD 13.x has many debugging features turned on, in both the kernel 21 and userland. These features attempt to detect incorrect use of 22 system primitives, and encourage loud failure through extra sanity 23 checking and fail stop semantics. They also substantially impact 24 system performance. If you want to do performance measurement, 25 benchmarking, and optimization, you'll want to turn them off. This 26 includes various WITNESS- related kernel options, INVARIANTS, malloc 27 debugging flags in userland, and various verbose features in the 28 kernel. Many developers choose to disable these features on build 29 machines to maximize performance. (To completely disable malloc 30 debugging, define MALLOC_PRODUCTION in /etc/make.conf, or to merely 31 disable the most expensive debugging functionality run 32 "ln -s 'abort:false,junk:false' /etc/malloc.conf".) 33 3420190304: 35 Clang, llvm, lld, lldb, compiler-rt and libc++ have been upgraded to 36 8.0.0. Please see the 20141231 entry below for information about 37 prerequisites and upgrading, if you are not already using clang 3.5.0 38 or higher. 39 4020190219: 41 drm and drm2 have been removed from the tree. Please see 42 https://wiki.freebsd.org/Graphics for the latest information on 43 migrating to the drm ports. 44 4520190131: 46 Iflib is no longer unconditionally compiled into the kernel. Drivers 47 using iflib and statically compiled into the kernel, now require 48 the 'device iflib' config option. For the same drivers loaded as 49 modules on kernels not having 'device iflib', the iflib.ko module 50 is loaded automatically. 51 5220190125: 53 The IEEE80211_AMPDU_AGE and AH_SUPPORT_AR5416 kernel configuration 54 options no longer exist since r343219 and r343427 respectively; 55 nothing uses them, so they should be just removed from custom 56 kernel config files. 57 5820181230: 59 r342635 changes the way efibootmgr(8) works by requiring users to add 60 the -b (bootnum) parameter for commands where the bootnum was previously 61 specified with each option. For example 'efibootmgr -B 0001' is now 62 'efibootmgr -B -b 0001'. 63 6420181220: 65 r342286 modifies the NFSv4 server so that it obeys vfs.nfsd.nfs_privport 66 in the same as it is applied to NFSv2 and 3. This implies that NFSv4 67 servers that have vfs.nfsd.nfs_privport set will only allow mounts 68 from clients using a reserved port#. Since both the FreeBSD and Linux 69 NFSv4 clients use reserved port#s by default, this should not affect 70 most NFSv4 mounts. 71 7220181219: 73 The XLP config has been removed. We can't support 64-bit atomics in this 74 kernel because it is running in 32-bit mode. XLP users must transition 75 to running a 64-bit kernel (XLP64 or XLPN32). 76 77 The mips GXEMUL support has been removed from FreeBSD. MALTA* + qemu is 78 the preferred emulator today and we don't need two different ones. 79 80 The old sibyte / swarm / Broadcom BCM1250 support has been 81 removed from the mips port. 82 8320181211: 84 Clang, llvm, lld, lldb, compiler-rt and libc++ have been upgraded to 85 7.0.1. Please see the 20141231 entry below for information about 86 prerequisites and upgrading, if you are not already using clang 3.5.0 87 or higher. 88 8920181211: 90 Remove the timed and netdate programs from the base tree. Setting 91 the time with these deamons has been obsolete for over a decade. 92 9320181126: 94 On amd64, arm64 and armv7 (architectures that install LLVM's ld.lld 95 linker as /usr/bin/ld) GNU ld is no longer installed as ld.bfd, as 96 it produces broken binaries when ifuncs are in use. Users needing 97 GNU ld should install the binutils port or package. 98 9920181123: 100 The BSD crtbegin and crtend code has been enabled by default. It has 101 had extensive testing on amd64, arm64, and i386. It can be disabled 102 by building a world with -DWITHOUT_BSD_CRTBEGIN. 103 10420181115: 105 The set of CTM commands (ctm, ctm_smail, ctm_rmail, ctm_dequeue) 106 has been converted to a port (misc/ctm) and will be removed from 107 FreeBSD-13. It is available as a package (ctm) for all supported 108 FreeBSD versions. 109 11020181110: 111 The default newsyslog.conf(5) file has been changed to only include 112 files in /etc/newsyslog.conf.d/ and /usr/local/etc/newsyslog.conf.d/ if 113 the filenames end in '.conf' and do not begin with a '.'. 114 115 You should check the configuration files in these two directories match 116 this naming convention. You can verify which configuration files are 117 being included using the command: 118 $ newsyslog -Nrv 119 12020181015: 121 Ports for the DRM modules have been simplified. Now, amd64 users should 122 just install the drm-kmod port. All others should install 123 drm-legacy-kmod. 124 125 Graphics hardware that's newer than about 2010 usually works with 126 drm-kmod. For hardware older than 2013, however, some users will need 127 to use drm-legacy-kmod if drm-kmod doesn't work for them. Hardware older 128 than 2008 usually only works in drm-legacy-kmod. The graphics team can 129 only commit to hardware made since 2013 due to the complexity of the 130 market and difficulty to test all the older cards effectively. If you 131 have hardware supported by drm-kmod, you are strongly encouraged to use 132 that as you will get better support. 133 134 Other than KPI chasing, drm-legacy-kmod will not be updated. As outlined 135 elsewhere, the drm and drm2 modules will be eliminated from the src base 136 soon (with a limited exception for arm). Please update to the package 137 asap and report any issues to x11@freebsd.org. 138 139 Generally, anybody using the drm*-kmod packages should add 140 WITHOUT_DRM_MODULE=t and WITHOUT_DRM2_MODULE=t to avoid nasty 141 cross-threading surprises, especially with automatic driver 142 loading from X11 startup. These will become the defaults in 13-current 143 shortly. 144 14520181012: 146 The ixlv(4) driver has been renamed to iavf(4). As a consequence, 147 custom kernel and module loading configuration files must be updated 148 accordingly. Moreover, interfaces previous presented as ixlvN to the 149 system are now exposed as iavfN and network configuration files must 150 be adjusted as necessary. 151 15220181009: 153 OpenSSL has been updated to version 1.1.1. This update included 154 additional various API changes througout the base system. It is 155 important to rebuild third-party software after upgrading. The value 156 of __FreeBSD_version has been bumped accordingly. 157 15820181006: 159 The legacy DRM modules and drivers have now been added to the loader's 160 module blacklist, in favor of loading them with kld_list in rc.conf(5). 161 The module blacklist may be overridden with the loader.conf(5) 162 'module_blacklist' variable, but loading them via rc.conf(5) is strongly 163 encouraged. 164 16520181002: 166 The cam(4) based nda(4) driver will be used over nvd(4) by default on 167 powerpc64. You may set 'options NVME_USE_NVD=1' in your kernel conf or 168 loader tunable 'hw.nvme.use_nvd=1' if you wish to use the existing 169 driver. Make sure to edit /boot/etc/kboot.conf and fstab to use the 170 nda device name. 171 17220180913: 173 Reproducible build mode is now on by default, in preparation for 174 FreeBSD 12.0. This eliminates build metadata such as the user, 175 host, and time from the kernel (and uname), unless the working tree 176 corresponds to a modified checkout from a version control system. 177 The previous behavior can be obtained by setting the /etc/src.conf 178 knob WITHOUT_REPRODUCIBLE_BUILD. 179 18020180826: 181 The Yarrow CSPRNG has been removed from the kernel as it has not been 182 supported by its designers since at least 2003. Fortuna has been the 183 default since FreeBSD-11. 184 18520180822: 186 devctl freeze/thaw have gone into the tree, the rc scripts have been 187 updated to use them and devmatch has been changed. You should update 188 kernel, userland and rc scripts all at the same time. 189 19020180818: 191 The default interpreter has been switched from 4th to Lua. 192 LOADER_DEFAULT_INTERP, documented in build(7), will override the default 193 interpreter. If you have custom FORTH code you will need to set 194 LOADER_DEFAULT_INTERP=4th (valid values are 4th, lua or simp) in 195 src.conf for the build. This will create default hard links between 196 loader and loader_4th instead of loader and loader_lua, the new default. 197 If you are using UEFI it will create the proper hard link to loader.efi. 198 199 bhyve uses userboot.so. It remains 4th-only until some issues are solved 200 regarding coexisting with multiple versions of FreeBSD are resolved. 201 20220180815: 203 ls(1) now respects the COLORTERM environment variable used in other 204 systems and software to indicate that a colored terminal is both 205 supported and desired. If ls(1) is suddenly emitting colors, they may 206 be disabled again by either removing the unwanted COLORTERM from your 207 environment, or using `ls --color=never`. The ls(1) specific CLICOLOR 208 may not be observed in a future release. 209 21020180808: 211 The default pager for most commands has been changed to "less". To 212 restore the old behavior, set PAGER="more" and MANPAGER="more -s" in 213 your environment. 214 21520180731: 216 The jedec_ts(4) driver has been removed. A superset of its functionality 217 is available in the jedec_dimm(4) driver, and the manpage for that 218 driver includes migration instructions. If you have "device jedec_ts" 219 in your kernel configuration file, it must be removed. 220 22120180730: 222 amd64/GENERIC now has EFI runtime services, EFIRT, enabled by default. 223 This should have no effect if the kernel is booted via BIOS/legacy boot. 224 EFIRT may be disabled via a loader tunable, efi.rt.disabled, if a system 225 has a buggy firmware that prevents a successful boot due to use of 226 runtime services. 227 22820180727: 229 Atmel AT91RM9200 and AT91SAM9, Cavium CNS 11xx and XScale 230 support has been removed from the tree. These ports were 231 obsolete and/or known to be broken for many years. 232 23320180723: 234 loader.efi has been augmented to participate more fully in the 235 UEFI boot manager protocol. loader.efi will now look at the 236 BootXXXX environment variable to determine if a specific kernel 237 or root partition was specified. XXXX is derived from BootCurrent. 238 efibootmgr(8) manages these standard UEFI variables. 239 24020180720: 241 zfsloader's functionality has now been folded into loader. 242 zfsloader is no longer necessary once you've updated your 243 boot blocks. For a transition period, we will install a 244 hardlink for zfsloader to loader to allow a smooth transition 245 until the boot blocks can be updated (hard link because old 246 zfs boot blocks don't understand symlinks). 247 24820180719: 249 ARM64 now have efifb support, if you want to have serial console 250 on your arm64 board when an screen is connected and the bootloader 251 setup a framebuffer for us to use, just add : 252 boot_serial=YES 253 boot_multicons=YES 254 in /boot/loader.conf 255 For Raspberry Pi 3 (RPI) users, this is needed even if you don't have 256 an screen connected as the firmware will setup a framebuffer are that 257 u-boot will expose as an EFI framebuffer. 258 25920180719: 260 New uid:gid added, ntpd:ntpd (123:123). Be sure to run mergemaster 261 or take steps to update /etc/passwd before doing installworld on 262 existing systems. Do not skip the "mergemaster -Fp" step before 263 installworld, as described in the update procedures near the bottom 264 of this document. Also, rc.d/ntpd now starts ntpd(8) as user ntpd 265 if the new mac_ntpd(4) policy is available, unless ntpd_flags or 266 the ntp config file contain options that change file/dir locations. 267 When such options (e.g., "statsdir" or "crypto") are used, ntpd can 268 still be run as non-root by setting ntpd_user=ntpd in rc.conf, after 269 taking steps to ensure that all required files/dirs are accessible 270 by the ntpd user. 271 27220180717: 273 Big endian arm support has been removed. 274 27520180711: 276 The static environment setup in kernel configs is no longer mutually 277 exclusive with the loader(8) environment by default. In order to 278 restore the previous default behavior of disabling the loader(8) 279 environment if a static environment is present, you must specify 280 loader_env.disabled=1 in the static environment. 281 28220180705: 283 The ABI of syscalls used by management tools like sockstat and 284 netstat has been broken to allow 32-bit binaries to work on 285 64-bit kernels without modification. These programs will need 286 to match the kernel in order to function. External programs may 287 require minor modifications to accommodate a change of type in 288 structures from pointers to 64-bit virtual addresses. 289 29020180702: 291 On i386 and amd64 atomics are now inlined. Out of tree modules using 292 atomics will need to be rebuilt. 293 29420180701: 295 The '%I' format in the kern.corefile sysctl limits the number of 296 core files that a process can generate to the number stored in the 297 debug.ncores sysctl. The '%I' format is replaced by the single digit 298 index. Previously, if all indexes were taken the kernel would overwrite 299 only a core file with the highest index in a filename. 300 Currently the system will create a new core file if there is a free 301 index or if all slots are taken it will overwrite the oldest one. 302 30320180630: 304 Clang, llvm, lld, lldb, compiler-rt and libc++ have been upgraded to 305 6.0.1. Please see the 20141231 entry below for information about 306 prerequisites and upgrading, if you are not already using clang 3.5.0 307 or higher. 308 30920180628: 310 r335753 introduced a new quoting method. However, etc/devd/devmatch.conf 311 needed to be changed to work with it. This change was made with r335763 312 and requires a mergemaster / etcupdate / etc to update the installed 313 file. 314 31520180612: 316 r334930 changed the interface between the NFS modules, so they all 317 need to be rebuilt. r335018 did a __FreeBSD_version bump for this. 318 31920180530: 320 As of r334391 lld is the default amd64 system linker; it is installed 321 as /usr/bin/ld. Kernel build workarounds (see 20180510 entry) are no 322 longer necessary. 323 32420180530: 325 The kernel / userland interface for devinfo changed, so you'll 326 need a new kernel and userland as a pair for it to work (rebuilding 327 lib/libdevinfo is all that's required). devinfo and devmatch will 328 not work, but everything else will when there's a mismatch. 329 33020180523: 331 The on-disk format for hwpmc callchain records has changed to include 332 threadid corresponding to a given record. This changes the field offsets 333 and thus requires that libpmcstat be rebuilt before using a kernel 334 later than r334108. 335 33620180517: 337 The vxge(4) driver has been removed. This driver was introduced into 338 HEAD one week before the Exar left the Ethernet market and is not 339 known to be used. If you have device vxge in your kernel config file 340 it must be removed. 341 34220180510: 343 The amd64 kernel now requires a ld that supports ifunc to produce a 344 working kernel, either lld or a newer binutils. lld is built by default 345 on amd64, and the 'buildkernel' target uses it automatically. However, 346 it is not the default linker, so building the kernel the traditional 347 way requires LD=ld.lld on the command line (or LD=/usr/local/bin/ld for 348 binutils port/package). lld will soon be default, and this requirement 349 will go away. 350 351 NOTE: As of r334391 lld is the default system linker on amd64, and no 352 workaround is necessary. 353 35420180508: 355 The nxge(4) driver has been removed. This driver was for PCI-X 10g 356 cards made by s2io/Neterion. The company was aquired by Exar and 357 no longer sells or supports Ethernet products. If you have device 358 nxge in your kernel config file it must be removed. 359 36020180504: 361 The tz database (tzdb) has been updated to 2018e. This version more 362 correctly models time stamps in time zones with negative DST such as 363 Europe/Dublin (from 1971 on), Europe/Prague (1946/7), and 364 Africa/Windhoek (1994/2017). This does not affect the UT offsets, only 365 time zone abbreviations and the tm_isdst flag. 366 36720180502: 368 The ixgb(4) driver has been removed. This driver was for an early and 369 uncommon legacy PCI 10GbE for a single ASIC, Intel 82597EX. Intel 370 quickly shifted to the long lived ixgbe family. If you have device 371 ixgb in your kernel config file it must be removed. 372 37320180501: 374 The lmc(4) driver has been removed. This was a WAN interface 375 card that was already reportedly rare in 2003, and had an ambiguous 376 license. If you have device lmc in your kernel config file it must 377 be removed. 378 37920180413: 380 Support for Arcnet networks has been removed. If you have device 381 arcnet or device cm in your kernel config file they must be 382 removed. 383 38420180411: 385 Support for FDDI networks has been removed. If you have device 386 fddi or device fpa in your kernel config file they must be 387 removed. 388 38920180406: 390 In addition to supporting RFC 3164 formatted messages, the 391 syslogd(8) service is now capable of parsing RFC 5424 formatted 392 log messages. The main benefit of using RFC 5424 is that clients 393 may now send log messages with timestamps containing year numbers, 394 microseconds and time zone offsets. 395 396 Similarly, the syslog(3) C library function has been altered to 397 send RFC 5424 formatted messages to the local system logging 398 daemon. On systems using syslogd(8), this change should have no 399 negative impact, as long as syslogd(8) and the C library are 400 updated at the same time. On systems using a different system 401 logging daemon, it may be necessary to make configuration 402 adjustments, depending on the software used. 403 404 When using syslog-ng, add the 'syslog-protocol' flag to local 405 input sources to enable parsing of RFC 5424 formatted messages: 406 407 source src { 408 unix-dgram("/var/run/log" flags(syslog-protocol)); 409 } 410 411 When using rsyslog, disable the 'SysSock.UseSpecialParser' option 412 of the 'imuxsock' module to let messages be processed by the 413 regular RFC 3164/5424 parsing pipeline: 414 415 module(load="imuxsock" SysSock.UseSpecialParser="off") 416 417 Do note that these changes only affect communication between local 418 applications and syslogd(8). The format that syslogd(8) uses to 419 store messages on disk or forward messages to other systems 420 remains unchanged. syslogd(8) still uses RFC 3164 for these 421 purposes. Options to customize this behaviour will be added in the 422 future. Utilities that process log files stored in /var/log are 423 thus expected to continue to function as before. 424 425 __FreeBSD_version has been incremented to 1200061 to denote this 426 change. 427 42820180328: 429 Support for token ring networks has been removed. If you 430 have "device token" in your kernel config you should remove 431 it. No device drivers supported token ring. 432 43320180323: 434 makefs was modified to be able to tag ISO9660 El Torito boot catalog 435 entries as EFI instead of overloading the i386 tag as done previously. 436 The amd64 mkisoimages.sh script used to build amd64 ISO images for 437 release was updated to use this. This may mean that makefs must be 438 updated before "make cdrom" can be run in the release directory. This 439 should be as simple as: 440 441 $ cd $SRCDIR/usr.sbin/makefs 442 $ make depend all install 443 44420180212: 445 FreeBSD boot loader enhanced with Lua scripting. It's purely opt-in for 446 now by building WITH_LOADER_LUA and WITHOUT_FORTH in /etc/src.conf. 447 Co-existance for the transition period will come shortly. Booting is a 448 complex environment and test coverage for Lua-enabled loaders has been 449 thin, so it would be prudent to assume it might not work and make 450 provisions for backup boot methods. 451 45220180211: 453 devmatch functionality has been turned on in devd. It will automatically 454 load drivers for unattached devices. This may cause unexpected drivers 455 to be loaded. Please report any problems to current@ and 456 imp@freebsd.org. 457 45820180114: 459 Clang, llvm, lld, lldb, compiler-rt and libc++ have been upgraded to 460 6.0.0. Please see the 20141231 entry below for information about 461 prerequisites and upgrading, if you are not already using clang 3.5.0 462 or higher. 463 46420180110: 465 LLVM's lld linker is now used as the FreeBSD/amd64 bootstrap linker. 466 This means it is used to link the kernel and userland libraries and 467 executables, but is not yet installed as /usr/bin/ld by default. 468 469 To revert to ld.bfd as the bootstrap linker, in /etc/src.conf set 470 WITHOUT_LLD_BOOTSTRAP=yes 471 47220180110: 473 On i386, pmtimer has been removed. Its functionality has been folded 474 into apm. It was a no-op on ACPI in current for a while now (but was 475 still needed on i386 in FreeBSD 11 and earlier). Users may need to 476 remove it from kernel config files. 477 47820180104: 479 The use of RSS hash from the network card aka flowid has been 480 disabled by default for lagg(4) as it's currently incompatible with 481 the lacp and loadbalance protocols. 482 483 This can be re-enabled by setting the following in loader.conf: 484 net.link.lagg.default_use_flowid="1" 485 48620180102: 487 The SW_WATCHDOG option is no longer necessary to enable the 488 hardclock-based software watchdog if no hardware watchdog is 489 configured. As before, SW_WATCHDOG will cause the software 490 watchdog to be enabled even if a hardware watchdog is configured. 491 49220171215: 493 r326887 fixes the issue described in the 20171214 UPDATING entry. 494 r326888 flips the switch back to building GELI support always. 495 49620171214: 497 r362593 broke ZFS + GELI support for reasons unknown. However, 498 it also broke ZFS support generally, so GELI has been turned off 499 by default as the lesser evil in r326857. If you boot off ZFS and/or 500 GELI, it might not be a good time to update. 501 50220171125: 503 PowerPC users must update loader(8) by rebuilding world before 504 installing a new kernel, as the protocol connecting them has 505 changed. Without the update, loader metadata will not be passed 506 successfully to the kernel and users will have to enter their 507 root partition at the kernel mountroot prompt to continue booting. 508 Newer versions of loader can boot old kernels without issue. 509 51020171110: 511 The LOADER_FIREWIRE_SUPPORT build variable as been renamed to 512 WITH/OUT_LOADER_FIREWIRE. LOADER_{NO_,}GELI_SUPPORT has been renamed 513 to WITH/OUT_LOADER_GELI. 514 51520171106: 516 The naive and non-compliant support of posix_fallocate(2) in ZFS 517 has been removed as of r325320. The system call now returns EINVAL 518 when used on a ZFS file. Although the new behavior complies with the 519 standard, some consumers are not prepared to cope with it. 520 One known victim is lld prior to r325420. 521 52220171102: 523 Building in a FreeBSD src checkout will automatically create object 524 directories now rather than store files in the current directory if 525 'make obj' was not ran. Calling 'make obj' is no longer necessary. 526 This feature can be disabled by setting WITHOUT_AUTO_OBJ=yes in 527 /etc/src-env.conf (not /etc/src.conf), or passing the option in the 528 environment. 529 53020171101: 531 The default MAKEOBJDIR has changed from /usr/obj/<srcdir> for native 532 builds, and /usr/obj/<arch>/<srcdir> for cross-builds, to a unified 533 /usr/obj/<srcdir>/<arch>. This behavior can be changed to the old 534 format by setting WITHOUT_UNIFIED_OBJDIR=yes in /etc/src-env.conf, 535 the environment, or with -DWITHOUT_UNIFIED_OBJDIR when building. 536 The UNIFIED_OBJDIR option is a transitional feature that will be 537 removed for 12.0 release; please migrate to the new format for any 538 tools by looking up the OBJDIR used by 'make -V .OBJDIR' means rather 539 than hardcoding paths. 540 54120171028: 542 The native-xtools target no longer installs the files by default to the 543 OBJDIR. Use the native-xtools-install target with a DESTDIR to install 544 to ${DESTDIR}/${NXTP} where NXTP defaults to /nxb-bin. 545 54620171021: 547 As part of the boot loader infrastructure cleanup, LOADER_*_SUPPORT 548 options are changing from controlling the build if defined / undefined 549 to controlling the build with explicit 'yes' or 'no' values. They will 550 shift to WITH/WITHOUT options to match other options in the system. 551 55220171010: 553 libstand has turned into a private library for sys/boot use only. 554 It is no longer supported as a public interface outside of sys/boot. 555 55620171005: 557 The arm port has split armv6 into armv6 and armv7. armv7 is now 558 a valid TARGET_ARCH/MACHINE_ARCH setting. If you have an armv7 system 559 and are running a kernel from before r324363, you will need to add 560 MACHINE_ARCH=armv7 to 'make buildworld' to do a native build. 561 56220171003: 563 When building multiple kernels using KERNCONF, non-existent KERNCONF 564 files will produce an error and buildkernel will fail. Previously 565 missing KERNCONF files silently failed giving no indication as to 566 why, only to subsequently discover during installkernel that the 567 desired kernel was never built in the first place. 568 56920170912: 570 The default serial number format for CTL LUNs has changed. This will 571 affect users who use /dev/diskid/* device nodes, or whose FibreChannel 572 or iSCSI clients care about their LUNs' serial numbers. Users who 573 require serial number stability should hardcode serial numbers in 574 /etc/ctl.conf . 575 57620170912: 577 For 32-bit arm compiled for hard-float support, soft-floating point 578 binaries now always get their shared libraries from 579 LD_SOFT_LIBRARY_PATH (in the past, this was only used if 580 /usr/libsoft also existed). Only users with a hard-float ld.so, but 581 soft-float everything else should be affected. 582 58320170826: 584 The geli password typed at boot is now hidden. To restore the previous 585 behavior, see geli(8) for configuration options. 586 58720170825: 588 Move PMTUD blackhole counters to TCPSTATS and remove them from bare 589 sysctl values. Minor nit, but requires a rebuild of both world/kernel 590 to complete. 591 59220170814: 593 "make check" behavior (made in ^/head@r295380) has been changed to 594 execute from a limited sandbox, as opposed to executing from 595 ${TESTSDIR}. 596 597 Behavioral changes: 598 - The "beforecheck" and "aftercheck" targets are now specified. 599 - ${CHECKDIR} (added in commit noted above) has been removed. 600 - Legacy behavior can be enabled by setting 601 WITHOUT_MAKE_CHECK_USE_SANDBOX in src.conf(5) or the environment. 602 603 If the limited sandbox mode is enabled, "make check" will execute 604 "make distribution", then install, execute the tests, and clean up the 605 sandbox if successful. 606 607 The "make distribution" and "make install" targets are typically run as 608 root to set appropriate permissions and ownership at installation time. 609 The end-user should set "WITH_INSTALL_AS_USER" in src.conf(5) or the 610 environment if executing "make check" with limited sandbox mode using 611 an unprivileged user. 612 61320170808: 614 Since the switch to GPT disk labels, fsck for UFS/FFS has been 615 unable to automatically find alternate superblocks. As of r322297, 616 the information needed to find alternate superblocks has been 617 moved to the end of the area reserved for the boot block. 618 Filesystems created with a newfs of this vintage or later 619 will create the recovery information. If you have a filesystem 620 created prior to this change and wish to have a recovery block 621 created for your filesystem, you can do so by running fsck in 622 foreground mode (i.e., do not use the -p or -y options). As it 623 starts, fsck will ask ``SAVE DATA TO FIND ALTERNATE SUPERBLOCKS'' 624 to which you should answer yes. 625 62620170728: 627 As of r321665, an NFSv4 server configuration that services 628 Kerberos mounts or clients that do not support the uid/gid in 629 owner/owner_group string capability, must explicitly enable 630 the nfsuserd daemon by adding nfsuserd_enable="YES" to the 631 machine's /etc/rc.conf file. 632 63320170722: 634 Clang, llvm, lldb, compiler-rt and libc++ have been upgraded to 5.0.0. 635 Please see the 20141231 entry below for information about prerequisites 636 and upgrading, if you are not already using clang 3.5.0 or higher. 637 63820170701: 639 WITHOUT_RCMDS is now the default. Set WITH_RCMDS if you need the 640 r-commands (rlogin, rsh, etc.) to be built with the base system. 641 64220170625: 643 The FreeBSD/powerpc platform now uses a 64-bit type for time_t. This is 644 a very major ABI incompatible change, so users of FreeBSD/powerpc must 645 be careful when performing source upgrades. It is best to run 646 'make installworld' from an alternate root system, either a live 647 CD/memory stick, or a temporary root partition. Additionally, all ports 648 must be recompiled. powerpc64 is largely unaffected, except in the case 649 of 32-bit compatibility. All 32-bit binaries will be affected. 650 65120170623: 652 Forward compatibility for the "ino64" project have been committed. This 653 will allow most new binaries to run on older kernels in a limited 654 fashion. This prevents many of the common foot-shooting actions in the 655 upgrade as well as the limited ability to roll back the kernel across 656 the ino64 upgrade. Complicated use cases may not work properly, though 657 enough simpler ones work to allow recovery in most situations. 658 65920170620: 660 Switch back to the BSDL dtc (Device Tree Compiler). Set WITH_GPL_DTC 661 if you require the GPL compiler. 662 66320170618: 664 The internal ABI used for communication between the NFS kernel modules 665 was changed by r320085, so __FreeBSD_version was bumped to 666 ensure all the NFS related modules are updated together. 667 66820170617: 669 The ABI of struct event was changed by extending the data 670 member to 64bit and adding ext fields. For upgrade, same 671 precautions as for the entry 20170523 "ino64" must be 672 followed. 673 67420170531: 675 The GNU roff toolchain has been removed from base. To render manpages 676 which are not supported by mandoc(1), man(1) can fallback on GNU roff 677 from ports (and recommends to install it). 678 To render roff(7) documents, consider using GNU roff from ports or the 679 heirloom doctools roff toolchain from ports via pkg install groff or 680 via pkg install heirloom-doctools. 681 68220170524: 683 The ath(4) and ath_hal(4) modules now build piecemeal to allow for 684 smaller runtime footprint builds. This is useful for embedded systems 685 which only require one chipset support. 686 687 If you load it as a module, make sure this is in /boot/loader.conf: 688 689 if_ath_load="YES" 690 691 This will load the HAL, all chip/RF backends and if_ath_pci. 692 If you have if_ath_pci in /boot/loader.conf, ensure it is after 693 if_ath or it will not load any HAL chipset support. 694 695 If you want to selectively load things (eg on ye cheape ARM/MIPS 696 platforms where RAM is at a premium) you should: 697 698 * load ath_hal 699 * load the chip modules in question 700 * load ath_rate, ath_dfs 701 * load ath_main 702 * load if_ath_pci and/or if_ath_ahb depending upon your particular 703 bus bind type - this is where probe/attach is done. 704 705 For further comments/feedback, poke adrian@ . 706 70720170523: 708 The "ino64" 64-bit inode project has been committed, which extends 709 a number of types to 64 bits. Upgrading in place requires care and 710 adherence to the documented upgrade procedure. 711 712 If using a custom kernel configuration ensure that the 713 COMPAT_FREEBSD11 option is included (as during the upgrade the 714 system will be running the ino64 kernel with the existing world). 715 716 For the safest in-place upgrade begin by removing previous build 717 artifacts via "rm -rf /usr/obj/*". Then, carefully follow the full 718 procedure documented below under the heading "To rebuild everything and 719 install it on the current system." Specifically, a reboot is required 720 after installing the new kernel before installing world. While an 721 installworld normally works by accident from multiuser after rebooting 722 the proper kernel, there are many cases where this will fail across this 723 upgrade and installworld from single user is required. 724 72520170424: 726 The NATM framework including the en(4), fatm(4), hatm(4), and 727 patm(4) devices has been removed. Consumers should plan a 728 migration before the end-of-life date for FreeBSD 11. 729 73020170420: 731 GNU diff has been replaced by a BSD licensed diff. Some features of GNU 732 diff has not been implemented, if those are needed a newer version of 733 GNU diff is available via the diffutils package under the gdiff name. 734 73520170413: 736 As of r316810 for ipfilter, keep frags is no longer assumed when 737 keep state is specified in a rule. r316810 aligns ipfilter with 738 documentation in man pages separating keep frags from keep state. 739 This allows keep state to be specified without forcing keep frags 740 and allows keep frags to be specified independently of keep state. 741 To maintain previous behaviour, also specify keep frags with 742 keep state (as documented in ipf.conf.5). 743 74420170407: 745 arm64 builds now use the base system LLD 4.0.0 linker by default, 746 instead of requiring that the aarch64-binutils port or package be 747 installed. To continue using aarch64-binutils, set 748 CROSS_BINUTILS_PREFIX=/usr/local/aarch64-freebsd/bin . 749 75020170405: 751 The UDP optimization in entry 20160818 that added the sysctl 752 net.inet.udp.require_l2_bcast has been reverted. L2 broadcast 753 packets will no longer be treated as L3 broadcast packets. 754 75520170331: 756 Binds and sends to the loopback addresses, IPv6 and IPv4, will now 757 use any explicitly assigned loopback address available in the jail 758 instead of using the first assigned address of the jail. 759 76020170329: 761 The ctl.ko module no longer implements the iSCSI target frontend: 762 cfiscsi.ko does instead. 763 764 If building cfiscsi.ko as a kernel module, the module can be loaded 765 via one of the following methods: 766 - `cfiscsi_load="YES"` in loader.conf(5). 767 - Add `cfiscsi` to `$kld_list` in rc.conf(5). 768 - ctladm(8)/ctld(8), when compiled with iSCSI support 769 (`WITH_ISCSI=yes` in src.conf(5)) 770 771 Please see cfiscsi(4) for more details. 772 77320170316: 774 The mmcsd.ko module now additionally depends on geom_flashmap.ko. 775 Also, mmc.ko and mmcsd.ko need to be a matching pair built from the 776 same source (previously, the dependency of mmcsd.ko on mmc.ko was 777 missing, but mmcsd.ko now will refuse to load if it is incompatible 778 with mmc.ko). 779 78020170315: 781 The syntax of ipfw(8) named states was changed to avoid ambiguity. 782 If you have used named states in the firewall rules, you need to modify 783 them after installworld and before rebooting. Now named states must 784 be prefixed with colon. 785 78620170311: 787 The old drm (sys/dev/drm/) drivers for i915 and radeon have been 788 removed as the userland we provide cannot use them. The KMS version 789 (sys/dev/drm2) supports the same hardware. 790 79120170302: 792 Clang, llvm, lldb, compiler-rt and libc++ have been upgraded to 4.0.0. 793 Please see the 20141231 entry below for information about prerequisites 794 and upgrading, if you are not already using clang 3.5.0 or higher. 795 79620170221: 797 The code that provides support for ZFS .zfs/ directory functionality 798 has been reimplemented. It's not possible now to create a snapshot 799 by mkdir under .zfs/snapshot/. That should be the only user visible 800 change. 801 80220170216: 803 EISA bus support has been removed. The WITH_EISA option is no longer 804 valid. 805 80620170215: 807 MCA bus support has been removed. 808 80920170127: 810 The WITH_LLD_AS_LD / WITHOUT_LLD_AS_LD build knobs have been renamed 811 WITH_LLD_IS_LD / WITHOUT_LLD_IS_LD, for consistency with CLANG_IS_CC. 812 81320170112: 814 The EM_MULTIQUEUE kernel configuration option is deprecated now that 815 the em(4) driver conforms to iflib specifications. 816 81720170109: 818 The igb(4), em(4) and lem(4) ethernet drivers are now implemented via 819 IFLIB. If you have a custom kernel configuration that excludes em(4) 820 but you use igb(4), you need to re-add em(4) to your custom 821 configuration. 822 82320161217: 824 Clang, llvm, lldb, compiler-rt and libc++ have been upgraded to 3.9.1. 825 Please see the 20141231 entry below for information about prerequisites 826 and upgrading, if you are not already using clang 3.5.0 or higher. 827 82820161124: 829 Clang, llvm, lldb, compiler-rt and libc++ have been upgraded to 3.9.0. 830 Please see the 20141231 entry below for information about prerequisites 831 and upgrading, if you are not already using clang 3.5.0 or higher. 832 83320161119: 834 The layout of the pmap structure has changed for powerpc to put the pmap 835 statistics at the front for all CPU variations. libkvm(3) and all tools 836 that link against it need to be recompiled. 837 83820161030: 839 isl(4) and cyapa(4) drivers now require a new driver, 840 chromebook_platform(4), to work properly on Chromebook-class hardware. 841 On other types of hardware the drivers may need to be configured using 842 device hints. Please see the corresponding manual pages for details. 843 84420161017: 845 The urtwn(4) driver was merged into rtwn(4) and now consists of 846 rtwn(4) main module + rtwn_usb(4) and rtwn_pci(4) bus-specific 847 parts. 848 Also, firmware for RTL8188CE was renamed due to possible name 849 conflict (rtwnrtl8192cU(B) -> rtwnrtl8192cE(B)) 850 85120161015: 852 GNU rcs has been removed from base. It is available as packages: 853 - rcs: Latest GPLv3 GNU rcs version. 854 - rcs57: Copy of the latest version of GNU rcs (GPLv2) before it was 855 removed from base. 856 85720161008: 858 Use of the cc_cdg, cc_chd, cc_hd, or cc_vegas congestion control 859 modules now requires that the kernel configuration contain the 860 TCP_HHOOK option. (This option is included in the GENERIC kernel.) 861 86220161003: 863 The WITHOUT_ELFCOPY_AS_OBJCOPY src.conf(5) knob has been retired. 864 ELF Tool Chain's elfcopy is always installed as /usr/bin/objcopy. 865 86620160924: 867 Relocatable object files with the extension of .So have been renamed 868 to use an extension of .pico instead. The purpose of this change is 869 to avoid a name clash with shared libraries on case-insensitive file 870 systems. On those file systems, foo.So is the same file as foo.so. 871 87220160918: 873 GNU rcs has been turned off by default. It can (temporarily) be built 874 again by adding WITH_RCS knob in src.conf. 875 Otherwise, GNU rcs is available from packages: 876 - rcs: Latest GPLv3 GNU rcs version. 877 - rcs57: Copy of the latest version of GNU rcs (GPLv2) from base. 878 87920160918: 880 The backup_uses_rcs functionality has been removed from rc.subr. 881 88220160908: 883 The queue(3) debugging macro, QUEUE_MACRO_DEBUG, has been split into 884 two separate components, QUEUE_MACRO_DEBUG_TRACE and 885 QUEUE_MACRO_DEBUG_TRASH. Define both for the original 886 QUEUE_MACRO_DEBUG behavior. 887 88820160824: 889 r304787 changed some ioctl interfaces between the iSCSI userspace 890 programs and the kernel. ctladm, ctld, iscsictl, and iscsid must be 891 rebuilt to work with new kernels. __FreeBSD_version has been bumped 892 to 1200005. 893 89420160818: 895 The UDP receive code has been updated to only treat incoming UDP 896 packets that were addressed to an L2 broadcast address as L3 897 broadcast packets. It is not expected that this will affect any 898 standards-conforming UDP application. The new behaviour can be 899 disabled by setting the sysctl net.inet.udp.require_l2_bcast to 900 0. 901 90220160818: 903 Remove the openbsd_poll system call. 904 __FreeBSD_version has been bumped because of this. 905 90620160708: 907 The stable/11 branch has been created from head@r302406. 908 90920160622: 910 The libc stub for the pipe(2) system call has been replaced with 911 a wrapper that calls the pipe2(2) system call and the pipe(2) 912 system call is now only implemented by the kernels that include 913 "options COMPAT_FREEBSD10" in their config file (this is the 914 default). Users should ensure that this option is enabled in 915 their kernel or upgrade userspace to r302092 before upgrading their 916 kernel. 917 91820160527: 919 CAM will now strip leading spaces from SCSI disks' serial numbers. 920 This will affect users who create UFS filesystems on SCSI disks using 921 those disk's diskid device nodes. For example, if /etc/fstab 922 previously contained a line like 923 "/dev/diskid/DISK-%20%20%20%20%20%20%20ABCDEFG0123456", you should 924 change it to "/dev/diskid/DISK-ABCDEFG0123456". Users of geom 925 transforms like gmirror may also be affected. ZFS users should 926 generally be fine. 927 92820160523: 929 The bitstring(3) API has been updated with new functionality and 930 improved performance. But it is binary-incompatible with the old API. 931 Objects built with the new headers may not be linked against objects 932 built with the old headers. 933 93420160520: 935 The brk and sbrk functions have been removed from libc on arm64. 936 Binutils from ports has been updated to not link to these 937 functions and should be updated to the latest version before 938 installing a new libc. 939 94020160517: 941 The armv6 port now defaults to hard float ABI. Limited support 942 for running both hardfloat and soft float on the same system 943 is available using the libraries installed with -DWITH_LIBSOFT. 944 This has only been tested as an upgrade path for installworld 945 and packages may fail or need manual intervention to run. New 946 packages will be needed. 947 948 To update an existing self-hosted armv6hf system, you must add 949 TARGET_ARCH=armv6 on the make command line for both the build 950 and the install steps. 951 95220160510: 953 Kernel modules compiled outside of a kernel build now default to 954 installing to /boot/modules instead of /boot/kernel. Many kernel 955 modules built this way (such as those in ports) already overrode 956 KMODDIR explicitly to install into /boot/modules. However, 957 manually building and installing a module from /sys/modules will 958 now install to /boot/modules instead of /boot/kernel. 959 96020160414: 961 The CAM I/O scheduler has been committed to the kernel. There should be 962 no user visible impact. This does enable NCQ Trim on ada SSDs. While the 963 list of known rogues that claim support for this but actually corrupt 964 data is believed to be complete, be on the lookout for data 965 corruption. The known rogue list is believed to be complete: 966 967 o Crucial MX100, M550 drives with MU01 firmware. 968 o Micron M510 and M550 drives with MU01 firmware. 969 o Micron M500 prior to MU07 firmware 970 o Samsung 830, 840, and 850 all firmwares 971 o FCCT M500 all firmwares 972 973 Crucial has firmware http://www.crucial.com/usa/en/support-ssd-firmware 974 with working NCQ TRIM. For Micron branded drives, see your sales rep for 975 updated firmware. Black listed drives will work correctly because these 976 drives work correctly so long as no NCQ TRIMs are sent to them. Given 977 this list is the same as found in Linux, it's believed there are no 978 other rogues in the market place. All other models from the above 979 vendors work. 980 981 To be safe, if you are at all concerned, you can quirk each of your 982 drives to prevent NCQ from being sent by setting: 983 kern.cam.ada.X.quirks="0x2" 984 in loader.conf. If the drive requires the 4k sector quirk, set the 985 quirks entry to 0x3. 986 98720160330: 988 The FAST_DEPEND build option has been removed and its functionality is 989 now the one true way. The old mkdep(1) style of 'make depend' has 990 been removed. See 20160311 for further details. 991 99220160317: 993 Resource range types have grown from unsigned long to uintmax_t. All 994 drivers, and anything using libdevinfo, need to be recompiled. 995 99620160311: 997 WITH_FAST_DEPEND is now enabled by default for in-tree and out-of-tree 998 builds. It no longer runs mkdep(1) during 'make depend', and the 999 'make depend' stage can safely be skipped now as it is auto ran 1000 when building 'make all' and will generate all SRCS and DPSRCS before 1001 building anything else. Dependencies are gathered at compile time with 1002 -MF flags kept in separate .depend files per object file. Users should 1003 run 'make cleandepend' once if using -DNO_CLEAN to clean out older 1004 stale .depend files. 1005 100620160306: 1007 On amd64, clang 3.8.0 can now insert sections of type AMD64_UNWIND into 1008 kernel modules. Therefore, if you load any kernel modules at boot time, 1009 please install the boot loaders after you install the kernel, but before 1010 rebooting, e.g.: 1011 1012 make buildworld 1013 make buildkernel KERNCONF=YOUR_KERNEL_HERE 1014 make installkernel KERNCONF=YOUR_KERNEL_HERE 1015 make -C sys/boot install 1016 <reboot in single user> 1017 1018 Then follow the usual steps, described in the General Notes section, 1019 below. 1020 102120160305: 1022 Clang, llvm, lldb and compiler-rt have been upgraded to 3.8.0. Please 1023 see the 20141231 entry below for information about prerequisites and 1024 upgrading, if you are not already using clang 3.5.0 or higher. 1025 102620160301: 1027 The AIO subsystem is now a standard part of the kernel. The 1028 VFS_AIO kernel option and aio.ko kernel module have been removed. 1029 Due to stability concerns, asynchronous I/O requests are only 1030 permitted on sockets and raw disks by default. To enable 1031 asynchronous I/O requests on all file types, set the 1032 vfs.aio.enable_unsafe sysctl to a non-zero value. 1033 103420160226: 1035 The ELF object manipulation tool objcopy is now provided by the 1036 ELF Tool Chain project rather than by GNU binutils. It should be a 1037 drop-in replacement, with the addition of arm64 support. The 1038 (temporary) src.conf knob WITHOUT_ELFCOPY_AS_OBJCOPY knob may be set 1039 to obtain the GNU version if necessary. 1040 104120160129: 1042 Building ZFS pools on top of zvols is prohibited by default. That 1043 feature has never worked safely; it's always been prone to deadlocks. 1044 Using a zvol as the backing store for a VM guest's virtual disk will 1045 still work, even if the guest is using ZFS. Legacy behavior can be 1046 restored by setting vfs.zfs.vol.recursive=1. 1047 104820160119: 1049 The NONE and HPN patches has been removed from OpenSSH. They are 1050 still available in the security/openssh-portable port. 1051 105220160113: 1053 With the addition of ypldap(8), a new _ypldap user is now required 1054 during installworld. "mergemaster -p" can be used to add the user 1055 prior to installworld, as documented in the handbook. 1056 105720151216: 1058 The tftp loader (pxeboot) now uses the option root-path directive. As a 1059 consequence it no longer looks for a pxeboot.4th file on the tftp 1060 server. Instead it uses the regular /boot infrastructure as with the 1061 other loaders. 1062 106320151211: 1064 The code to start recording plug and play data into the modules has 1065 been committed. While the old tools will properly build a new kernel, 1066 a number of warnings about "unknown metadata record 4" will be produced 1067 for an older kldxref. To avoid such warnings, make sure to rebuild 1068 the kernel toolchain (or world). Make sure that you have r292078 or 1069 later when trying to build 292077 or later before rebuilding. 1070 107120151207: 1072 Debug data files are now built by default with 'make buildworld' and 1073 installed with 'make installworld'. This facilitates debugging but 1074 requires more disk space both during the build and for the installed 1075 world. Debug files may be disabled by setting WITHOUT_DEBUG_FILES=yes 1076 in src.conf(5). 1077 107820151130: 1079 r291527 changed the internal interface between the nfsd.ko and 1080 nfscommon.ko modules. As such, they must both be upgraded to-gether. 1081 __FreeBSD_version has been bumped because of this. 1082 108320151108: 1084 Add support for unicode collation strings leads to a change of 1085 order of files listed by ls(1) for example. To get back to the old 1086 behaviour, set LC_COLLATE environment variable to "C". 1087 1088 Databases administrators will need to reindex their databases given 1089 collation results will be different. 1090 1091 Due to a bug in install(1) it is recommended to remove the ancient 1092 locales before running make installworld. 1093 1094 rm -rf /usr/share/locale/* 1095 109620151030: 1097 The OpenSSL has been upgraded to 1.0.2d. Any binaries requiring 1098 libcrypto.so.7 or libssl.so.7 must be recompiled. 1099 110020151020: 1101 Qlogic 24xx/25xx firmware images were updated from 5.5.0 to 7.3.0. 1102 Kernel modules isp_2400_multi and isp_2500_multi were removed and 1103 should be replaced with isp_2400 and isp_2500 modules respectively. 1104 110520151017: 1106 The build previously allowed using 'make -n' to not recurse into 1107 sub-directories while showing what commands would be executed, and 1108 'make -n -n' to recursively show commands. Now 'make -n' will recurse 1109 and 'make -N' will not. 1110 111120151012: 1112 If you specify SENDMAIL_MC or SENDMAIL_CF in make.conf, mergemaster 1113 and etcupdate will now use this file. A custom sendmail.cf is now 1114 updated via this mechanism rather than via installworld. If you had 1115 excluded sendmail.cf in mergemaster.rc or etcupdate.conf, you may 1116 want to remove the exclusion or change it to "always install". 1117 /etc/mail/sendmail.cf is now managed the same way regardless of 1118 whether SENDMAIL_MC/SENDMAIL_CF is used. If you are not using 1119 SENDMAIL_MC/SENDMAIL_CF there should be no change in behavior. 1120 112120151011: 1122 Compatibility shims for legacy ATA device names have been removed. 1123 It includes ATA_STATIC_ID kernel option, kern.cam.ada.legacy_aliases 1124 and kern.geom.raid.legacy_aliases loader tunables, kern.devalias.* 1125 environment variables, /dev/ad* and /dev/ar* symbolic links. 1126 112720151006: 1128 Clang, llvm, lldb, compiler-rt and libc++ have been upgraded to 3.7.0. 1129 Please see the 20141231 entry below for information about prerequisites 1130 and upgrading, if you are not already using clang 3.5.0 or higher. 1131 113220150924: 1133 Kernel debug files have been moved to /usr/lib/debug/boot/kernel/, 1134 and renamed from .symbols to .debug. This reduces the size requirements 1135 on the boot partition or file system and provides consistency with 1136 userland debug files. 1137 1138 When using the supported kernel installation method the 1139 /usr/lib/debug/boot/kernel directory will be renamed (to kernel.old) 1140 as is done with /boot/kernel. 1141 1142 Developers wishing to maintain the historical behavior of installing 1143 debug files in /boot/kernel/ can set KERN_DEBUGDIR="" in src.conf(5). 1144 114520150827: 1146 The wireless drivers had undergone changes that remove the 'parent 1147 interface' from the ifconfig -l output. The rc.d network scripts 1148 used to check presence of a parent interface in the list, so old 1149 scripts would fail to start wireless networking. Thus, etcupdate(3) 1150 or mergemaster(8) run is required after kernel update, to update your 1151 rc.d scripts in /etc. 1152 115320150827: 1154 pf no longer supports 'scrub fragment crop' or 'scrub fragment drop-ovl' 1155 These configurations are now automatically interpreted as 1156 'scrub fragment reassemble'. 1157 115820150817: 1159 Kernel-loadable modules for the random(4) device are back. To use 1160 them, the kernel must have 1161 1162 device random 1163 options RANDOM_LOADABLE 1164 1165 kldload(8) can then be used to load random_fortuna.ko 1166 or random_yarrow.ko. Please note that due to the indirect 1167 function calls that the loadable modules need to provide, 1168 the build-in variants will be slightly more efficient. 1169 1170 The random(4) kernel option RANDOM_DUMMY has been retired due to 1171 unpopularity. It was not all that useful anyway. 1172 117320150813: 1174 The WITHOUT_ELFTOOLCHAIN_TOOLS src.conf(5) knob has been retired. 1175 Control over building the ELF Tool Chain tools is now provided by 1176 the WITHOUT_TOOLCHAIN knob. 1177 117820150810: 1179 The polarity of Pulse Per Second (PPS) capture events with the 1180 uart(4) driver has been corrected. Prior to this change the PPS 1181 "assert" event corresponded to the trailing edge of a positive PPS 1182 pulse and the "clear" event was the leading edge of the next pulse. 1183 1184 As the width of a PPS pulse in a typical GPS receiver is on the 1185 order of 1 millisecond, most users will not notice any significant 1186 difference with this change. 1187 1188 Anyone who has compensated for the historical polarity reversal by 1189 configuring a negative offset equal to the pulse width will need to 1190 remove that workaround. 1191 119220150809: 1193 The default group assigned to /dev/dri entries has been changed 1194 from 'wheel' to 'video' with the id of '44'. If you want to have 1195 access to the dri devices please add yourself to the video group 1196 with: 1197 1198 # pw groupmod video -m $USER 1199 120020150806: 1201 The menu.rc and loader.rc files will now be replaced during 1202 upgrades. Please migrate local changes to menu.rc.local and 1203 loader.rc.local instead. 1204 120520150805: 1206 GNU Binutils versions of addr2line, c++filt, nm, readelf, size, 1207 strings and strip have been removed. The src.conf(5) knob 1208 WITHOUT_ELFTOOLCHAIN_TOOLS no longer provides the binutils tools. 1209 121020150728: 1211 As ZFS requires more kernel stack pages than is the default on some 1212 architectures e.g. i386, it now warns if KSTACK_PAGES is less than 1213 ZFS_MIN_KSTACK_PAGES (which is 4 at the time of writing). 1214 1215 Please consider using 'options KSTACK_PAGES=X' where X is greater 1216 than or equal to ZFS_MIN_KSTACK_PAGES i.e. 4 in such configurations. 1217 121820150706: 1219 sendmail has been updated to 8.15.2. Starting with FreeBSD 11.0 1220 and sendmail 8.15, sendmail uses uncompressed IPv6 addresses by 1221 default, i.e., they will not contain "::". For example, instead 1222 of ::1, it will be 0:0:0:0:0:0:0:1. This permits a zero subnet 1223 to have a more specific match, such as different map entries for 1224 IPv6:0:0 vs IPv6:0. This change requires that configuration 1225 data (including maps, files, classes, custom ruleset, etc.) must 1226 use the same format, so make certain such configuration data is 1227 upgrading. As a very simple check search for patterns like 1228 'IPv6:[0-9a-fA-F:]*::' and 'IPv6::'. To return to the old 1229 behavior, set the m4 option confUSE_COMPRESSED_IPV6_ADDRESSES or 1230 the cf option UseCompressedIPv6Addresses. 1231 123220150630: 1233 The default kernel entropy-processing algorithm is now 1234 Fortuna, replacing Yarrow. 1235 1236 Assuming you have 'device random' in your kernel config 1237 file, the configurations allow a kernel option to override 1238 this default. You may choose *ONE* of: 1239 1240 options RANDOM_YARROW # Legacy /dev/random algorithm. 1241 options RANDOM_DUMMY # Blocking-only driver. 1242 1243 If you have neither, you get Fortuna. For most people, 1244 read no further, Fortuna will give a /dev/random that works 1245 like it always used to, and the difference will be irrelevant. 1246 1247 If you remove 'device random', you get *NO* kernel-processed 1248 entropy at all. This may be acceptable to folks building 1249 embedded systems, but has complications. Carry on reading, 1250 and it is assumed you know what you need. 1251 1252 *PLEASE* read random(4) and random(9) if you are in the 1253 habit of tweaking kernel configs, and/or if you are a member 1254 of the embedded community, wanting specific and not-usual 1255 behaviour from your security subsystems. 1256 1257 NOTE!! If you use RANDOM_DUMMY and/or have no 'device 1258 random', you will NOT have a functioning /dev/random, and 1259 many cryptographic features will not work, including SSH. 1260 You may also find strange behaviour from the random(3) set 1261 of library functions, in particular sranddev(3), srandomdev(3) 1262 and arc4random(3). The reason for this is that the KERN_ARND 1263 sysctl only returns entropy if it thinks it has some to 1264 share, and with RANDOM_DUMMY or no 'device random' this 1265 will never happen. 1266 126720150623: 1268 An additional fix for the issue described in the 20150614 sendmail 1269 entry below has been committed in revision 284717. 1270 127120150616: 1272 FreeBSD's old make (fmake) has been removed from the system. It is 1273 available as the devel/fmake port or via pkg install fmake. 1274 127520150615: 1276 The fix for the issue described in the 20150614 sendmail entry 1277 below has been committed in revision 284436. The work 1278 around described in that entry is no longer needed unless the 1279 default setting is overridden by a confDH_PARAMETERS configuration 1280 setting of '5' or pointing to a 512 bit DH parameter file. 1281 128220150614: 1283 ALLOW_DEPRECATED_ATF_TOOLS/ATFFILE support has been removed from 1284 atf.test.mk (included from bsd.test.mk). Please upgrade devel/atf 1285 and devel/kyua to version 0.20+ and adjust any calling code to work 1286 with Kyuafile and kyua. 1287 128820150614: 1289 The import of openssl to address the FreeBSD-SA-15:10.openssl 1290 security advisory includes a change which rejects handshakes 1291 with DH parameters below 768 bits. sendmail releases prior 1292 to 8.15.2 (not yet released), defaulted to a 512 bit 1293 DH parameter setting for client connections. To work around 1294 this interoperability, sendmail can be configured to use a 1295 2048 bit DH parameter by: 1296 1297 1. Edit /etc/mail/`hostname`.mc 1298 2. If a setting for confDH_PARAMETERS does not exist or 1299 exists and is set to a string beginning with '5', 1300 replace it with '2'. 1301 3. If a setting for confDH_PARAMETERS exists and is set to 1302 a file path, create a new file with: 1303 openssl dhparam -out /path/to/file 2048 1304 4. Rebuild the .cf file: 1305 cd /etc/mail/; make; make install 1306 5. Restart sendmail: 1307 cd /etc/mail/; make restart 1308 1309 A sendmail patch is coming, at which time this file will be 1310 updated. 1311 131220150604: 1313 Generation of legacy formatted entries have been disabled by default 1314 in pwd_mkdb(8), as all base system consumers of the legacy formatted 1315 entries were converted to use the new format by default when the new, 1316 machine independent format have been added and supported since FreeBSD 1317 5.x. 1318 1319 Please see the pwd_mkdb(8) manual page for further details. 1320 132120150525: 1322 Clang and llvm have been upgraded to 3.6.1 release. Please see the 1323 20141231 entry below for information about prerequisites and upgrading, 1324 if you are not already using 3.5.0 or higher. 1325 132620150521: 1327 TI platform code switched to using vendor DTS files and this update 1328 may break existing systems running on Beaglebone, Beaglebone Black, 1329 and Pandaboard: 1330 1331 - dtb files should be regenerated/reinstalled. Filenames are the 1332 same but content is different now 1333 - GPIO addressing was changed, now each GPIO bank (32 pins per bank) 1334 has its own /dev/gpiocX device, e.g. pin 121 on /dev/gpioc0 in old 1335 addressing scheme is now pin 25 on /dev/gpioc3. 1336 - Pandaboard: /etc/ttys should be updated, serial console device is 1337 now /dev/ttyu2, not /dev/ttyu0 1338 133920150501: 1340 soelim(1) from gnu/usr.bin/groff has been replaced by usr.bin/soelim. 1341 If you need the GNU extension from groff soelim(1), install groff 1342 from package: pkg install groff, or via ports: textproc/groff. 1343 134420150423: 1345 chmod, chflags, chown and chgrp now affect symlinks in -R mode as 1346 defined in symlink(7); previously symlinks were silently ignored. 1347 134820150415: 1349 The const qualifier has been removed from iconv(3) to comply with 1350 POSIX. The ports tree is aware of this from r384038 onwards. 1351 135220150416: 1353 Libraries specified by LIBADD in Makefiles must have a corresponding 1354 DPADD_<lib> variable to ensure correct dependencies. This is now 1355 enforced in src.libnames.mk. 1356 135720150324: 1358 From legacy ata(4) driver was removed support for SATA controllers 1359 supported by more functional drivers ahci(4), siis(4) and mvs(4). 1360 Kernel modules ataahci and ataadaptec were removed completely, 1361 replaced by ahci and mvs modules respectively. 1362 136320150315: 1364 Clang, llvm and lldb have been upgraded to 3.6.0 release. Please see 1365 the 20141231 entry below for information about prerequisites and 1366 upgrading, if you are not already using 3.5.0 or higher. 1367 136820150307: 1369 The 32-bit PowerPC kernel has been changed to a position-independent 1370 executable. This can only be booted with a version of loader(8) 1371 newer than January 31, 2015, so make sure to update both world and 1372 kernel before rebooting. 1373 137420150217: 1375 If you are running a -CURRENT kernel since r273872 (Oct 30th, 2014), 1376 but before r278950, the RNG was not seeded properly. Immediately 1377 upgrade the kernel to r278950 or later and regenerate any keys (e.g. 1378 ssh keys or openssl keys) that were generated w/ a kernel from that 1379 range. This does not affect programs that directly used /dev/random 1380 or /dev/urandom. All userland uses of arc4random(3) are affected. 1381 138220150210: 1383 The autofs(4) ABI was changed in order to restore binary compatibility 1384 with 10.1-RELEASE. The automountd(8) daemon needs to be rebuilt to work 1385 with the new kernel. 1386 138720150131: 1388 The powerpc64 kernel has been changed to a position-independent 1389 executable. This can only be booted with a new version of loader(8), 1390 so make sure to update both world and kernel before rebooting. 1391 139220150118: 1393 Clang and llvm have been upgraded to 3.5.1 release. This is a bugfix 1394 only release, no new features have been added. Please see the 20141231 1395 entry below for information about prerequisites and upgrading, if you 1396 are not already using 3.5.0. 1397 139820150107: 1399 ELF tools addr2line, elfcopy (strip), nm, size, and strings are now 1400 taken from the ELF Tool Chain project rather than GNU binutils. They 1401 should be drop-in replacements, with the addition of arm64 support. 1402 The WITHOUT_ELFTOOLCHAIN_TOOLS= knob may be used to obtain the 1403 binutils tools, if necessary. See 20150805 for updated information. 1404 140520150105: 1406 The default Unbound configuration now enables remote control 1407 using a local socket. Users who have already enabled the 1408 local_unbound service should regenerate their configuration 1409 by running "service local_unbound setup" as root. 1410 141120150102: 1412 The GNU texinfo and GNU info pages have been removed. 1413 To be able to view GNU info pages please install texinfo from ports. 1414 141520141231: 1416 Clang, llvm and lldb have been upgraded to 3.5.0 release. 1417 1418 As of this release, a prerequisite for building clang, llvm and lldb is 1419 a C++11 capable compiler and C++11 standard library. This means that to 1420 be able to successfully build the cross-tools stage of buildworld, with 1421 clang as the bootstrap compiler, your system compiler or cross compiler 1422 should either be clang 3.3 or later, or gcc 4.8 or later, and your 1423 system C++ library should be libc++, or libdstdc++ from gcc 4.8 or 1424 later. 1425 1426 On any standard FreeBSD 10.x or 11.x installation, where clang and 1427 libc++ are on by default (that is, on x86 or arm), this should work out 1428 of the box. 1429 1430 On 9.x installations where clang is enabled by default, e.g. on x86 and 1431 powerpc, libc++ will not be enabled by default, so libc++ should be 1432 built (with clang) and installed first. If both clang and libc++ are 1433 missing, build clang first, then use it to build libc++. 1434 1435 On 8.x and earlier installations, upgrade to 9.x first, and then follow 1436 the instructions for 9.x above. 1437 1438 Sparc64 and mips users are unaffected, as they still use gcc 4.2.1 by 1439 default, and do not build clang. 1440 1441 Many embedded systems are resource constrained, and will not be able to 1442 build clang in a reasonable time, or in some cases at all. In those 1443 cases, cross building bootable systems on amd64 is a workaround. 1444 1445 This new version of clang introduces a number of new warnings, of which 1446 the following are most likely to appear: 1447 1448 -Wabsolute-value 1449 1450 This warns in two cases, for both C and C++: 1451 * When the code is trying to take the absolute value of an unsigned 1452 quantity, which is effectively a no-op, and almost never what was 1453 intended. The code should be fixed, if at all possible. If you are 1454 sure that the unsigned quantity can be safely cast to signed, without 1455 loss of information or undefined behavior, you can add an explicit 1456 cast, or disable the warning. 1457 1458 * When the code is trying to take an absolute value, but the called 1459 abs() variant is for the wrong type, which can lead to truncation. 1460 If you want to disable the warning instead of fixing the code, please 1461 make sure that truncation will not occur, or it might lead to unwanted 1462 side-effects. 1463 1464 -Wtautological-undefined-compare and 1465 -Wundefined-bool-conversion 1466 1467 These warn when C++ code is trying to compare 'this' against NULL, while 1468 'this' should never be NULL in well-defined C++ code. However, there is 1469 some legacy (pre C++11) code out there, which actively abuses this 1470 feature, which was less strictly defined in previous C++ versions. 1471 1472 Squid and openjdk do this, for example. The warning can be turned off 1473 for C++98 and earlier, but compiling the code in C++11 mode might result 1474 in unexpected behavior; for example, the parts of the program that are 1475 unreachable could be optimized away. 1476 147720141222: 1478 The old NFS client and server (kernel options NFSCLIENT, NFSSERVER) 1479 kernel sources have been removed. The .h files remain, since some 1480 utilities include them. This will need to be fixed later. 1481 If "mount -t oldnfs ..." is attempted, it will fail. 1482 If the "-o" option on mountd(8), nfsd(8) or nfsstat(1) is used, 1483 the utilities will report errors. 1484 148520141121: 1486 The handling of LOCAL_LIB_DIRS has been altered to skip addition of 1487 directories to top level SUBDIR variable when their parent 1488 directory is included in LOCAL_DIRS. Users with build systems with 1489 such hierarchies and without SUBDIR entries in the parent 1490 directory Makefiles should add them or add the directories to 1491 LOCAL_DIRS. 1492 149320141109: 1494 faith(4) and faithd(8) have been removed from the base system. Faith 1495 has been obsolete for a very long time. 1496 149720141104: 1498 vt(4), the new console driver, is enabled by default. It brings 1499 support for Unicode and double-width characters, as well as 1500 support for UEFI and integration with the KMS kernel video 1501 drivers. 1502 1503 You may need to update your console settings in /etc/rc.conf, 1504 most probably the keymap. During boot, /etc/rc.d/syscons will 1505 indicate what you need to do. 1506 1507 vt(4) still has issues and lacks some features compared to 1508 syscons(4). See the wiki for up-to-date information: 1509 https://wiki.freebsd.org/Newcons 1510 1511 If you want to keep using syscons(4), you can do so by adding 1512 the following line to /boot/loader.conf: 1513 kern.vty=sc 1514 151520141102: 1516 pjdfstest has been integrated into kyua as an opt-in test suite. 1517 Please see share/doc/pjdfstest/README for more details on how to 1518 execute it. 1519 152020141009: 1521 gperf has been removed from the base system for architectures 1522 that use clang. Ports that require gperf will obtain it from the 1523 devel/gperf port. 1524 152520140923: 1526 pjdfstest has been moved from tools/regression/pjdfstest to 1527 contrib/pjdfstest . 1528 152920140922: 1530 At svn r271982, The default linux compat kernel ABI has been adjusted 1531 to 2.6.18 in support of the linux-c6 compat ports infrastructure 1532 update. If you wish to continue using the linux-f10 compat ports, 1533 add compat.linux.osrelease=2.6.16 to your local sysctl.conf. Users are 1534 encouraged to update their linux-compat packages to linux-c6 during 1535 their next update cycle. 1536 153720140729: 1538 The ofwfb driver, used to provide a graphics console on PowerPC when 1539 using vt(4), no longer allows mmap() of all physical memory. This 1540 will prevent Xorg on PowerPC with some ATI graphics cards from 1541 initializing properly unless x11-servers/xorg-server is updated to 1542 1.12.4_8 or newer. 1543 154420140723: 1545 The xdev targets have been converted to using TARGET and 1546 TARGET_ARCH instead of XDEV and XDEV_ARCH. 1547 154820140719: 1549 The default unbound configuration has been modified to address 1550 issues with reverse lookups on networks that use private 1551 address ranges. If you use the local_unbound service, run 1552 "service local_unbound setup" as root to regenerate your 1553 configuration, then "service local_unbound reload" to load the 1554 new configuration. 1555 155620140709: 1557 The GNU texinfo and GNU info pages are not built and installed 1558 anymore, WITH_INFO knob has been added to allow to built and install 1559 them again. 1560 UPDATE: see 20150102 entry on texinfo's removal 1561 156220140708: 1563 The GNU readline library is now an INTERNALLIB - that is, it is 1564 statically linked into consumers (GDB and variants) in the base 1565 system, and the shared library is no longer installed. The 1566 devel/readline port is available for third party software that 1567 requires readline. 1568 156920140702: 1570 The Itanium architecture (ia64) has been removed from the list of 1571 known architectures. This is the first step in the removal of the 1572 architecture. 1573 157420140701: 1575 Commit r268115 has added NFSv4.1 server support, merged from 1576 projects/nfsv4.1-server. Since this includes changes to the 1577 internal interfaces between the NFS related modules, a full 1578 build of the kernel and modules will be necessary. 1579 __FreeBSD_version has been bumped. 1580 158120140629: 1582 The WITHOUT_VT_SUPPORT kernel config knob has been renamed 1583 WITHOUT_VT. (The other _SUPPORT knobs have a consistent meaning 1584 which differs from the behaviour controlled by this knob.) 1585 158620140619: 1587 Maximal length of the serial number in CTL was increased from 16 to 1588 64 chars, that breaks ABI. All CTL-related tools, such as ctladm 1589 and ctld, need to be rebuilt to work with a new kernel. 1590 159120140606: 1592 The libatf-c and libatf-c++ major versions were downgraded to 0 and 1593 1 respectively to match the upstream numbers. They were out of 1594 sync because, when they were originally added to FreeBSD, the 1595 upstream versions were not respected. These libraries are private 1596 and not yet built by default, so renumbering them should be a 1597 non-issue. However, unclean source trees will yield broken test 1598 programs once the operator executes "make delete-old-libs" after a 1599 "make installworld". 1600 1601 Additionally, the atf-sh binary was made private by moving it into 1602 /usr/libexec/. Already-built shell test programs will keep the 1603 path to the old binary so they will break after "make delete-old" 1604 is run. 1605 1606 If you are using WITH_TESTS=yes (not the default), wipe the object 1607 tree and rebuild from scratch to prevent spurious test failures. 1608 This is only needed once: the misnumbered libraries and misplaced 1609 binaries have been added to OptionalObsoleteFiles.inc so they will 1610 be removed during a clean upgrade. 1611 161220140512: 1613 Clang and llvm have been upgraded to 3.4.1 release. 1614 161520140508: 1616 We bogusly installed src.opts.mk in /usr/share/mk. This file should 1617 be removed to avoid issues in the future (and has been added to 1618 ObsoleteFiles.inc). 1619 162020140505: 1621 /etc/src.conf now affects only builds of the FreeBSD src tree. In the 1622 past, it affected all builds that used the bsd.*.mk files. The old 1623 behavior was a bug, but people may have relied upon it. To get this 1624 behavior back, you can .include /etc/src.conf from /etc/make.conf 1625 (which is still global and isn't changed). This also changes the 1626 behavior of incremental builds inside the tree of individual 1627 directories. Set MAKESYSPATH to ".../share/mk" to do that. 1628 Although this has survived make universe and some upgrade scenarios, 1629 other upgrade scenarios may have broken. At least one form of 1630 temporary breakage was fixed with MAKESYSPATH settings for buildworld 1631 as well... In cases where MAKESYSPATH isn't working with this 1632 setting, you'll need to set it to the full path to your tree. 1633 1634 One side effect of all this cleaning up is that bsd.compiler.mk 1635 is no longer implicitly included by bsd.own.mk. If you wish to 1636 use COMPILER_TYPE, you must now explicitly include bsd.compiler.mk 1637 as well. 1638 163920140430: 1640 The lindev device has been removed since /dev/full has been made a 1641 standard device. __FreeBSD_version has been bumped. 1642 164320140424: 1644 The knob WITHOUT_VI was added to the base system, which controls 1645 building ex(1), vi(1), etc. Older releases of FreeBSD required ex(1) 1646 in order to reorder files share/termcap and didn't build ex(1) as a 1647 build tool, so building/installing with WITH_VI is highly advised for 1648 build hosts for older releases. 1649 1650 This issue has been fixed in stable/9 and stable/10 in r277022 and 1651 r276991, respectively. 1652 165320140418: 1654 The YES_HESIOD knob has been removed. It has been obsolete for 1655 a decade. Please move to using WITH_HESIOD instead or your builds 1656 will silently lack HESIOD. 1657 165820140405: 1659 The uart(4) driver has been changed with respect to its handling 1660 of the low-level console. Previously the uart(4) driver prevented 1661 any process from changing the baudrate or the CLOCAL and HUPCL 1662 control flags. By removing the restrictions, operators can make 1663 changes to the serial console port without having to reboot. 1664 However, when getty(8) is started on the serial device that is 1665 associated with the low-level console, a misconfigured terminal 1666 line in /etc/ttys will now have a real impact. 1667 Before upgrading the kernel, make sure that /etc/ttys has the 1668 serial console device configured as 3wire without baudrate to 1669 preserve the previous behaviour. E.g: 1670 ttyu0 "/usr/libexec/getty 3wire" vt100 on secure 1671 167220140306: 1673 Support for libwrap (TCP wrappers) in rpcbind was disabled by default 1674 to improve performance. To re-enable it, if needed, run rpcbind 1675 with command line option -W. 1676 167720140226: 1678 Switched back to the GPL dtc compiler due to updates in the upstream 1679 dts files not being supported by the BSDL dtc compiler. You will need 1680 to rebuild your kernel toolchain to pick up the new compiler. Core dumps 1681 may result while building dtb files during a kernel build if you fail 1682 to do so. Set WITHOUT_GPL_DTC if you require the BSDL compiler. 1683 168420140216: 1685 Clang and llvm have been upgraded to 3.4 release. 1686 168720140216: 1688 The nve(4) driver has been removed. Please use the nfe(4) driver 1689 for NVIDIA nForce MCP Ethernet adapters instead. 1690 169120140212: 1692 An ABI incompatibility crept into the libc++ 3.4 import in r261283. 1693 This could cause certain C++ applications using shared libraries built 1694 against the previous version of libc++ to crash. The incompatibility 1695 has now been fixed, but any C++ applications or shared libraries built 1696 between r261283 and r261801 should be recompiled. 1697 169820140204: 1699 OpenSSH will now ignore errors caused by kernel lacking of Capsicum 1700 capability mode support. Please note that enabling the feature in 1701 kernel is still highly recommended. 1702 170320140131: 1704 OpenSSH is now built with sandbox support, and will use sandbox as 1705 the default privilege separation method. This requires Capsicum 1706 capability mode support in kernel. 1707 170820140128: 1709 The libelf and libdwarf libraries have been updated to newer 1710 versions from upstream. Shared library version numbers for 1711 these two libraries were bumped. Any ports or binaries 1712 requiring these two libraries should be recompiled. 1713 __FreeBSD_version is bumped to 1100006. 1714 171520140110: 1716 If a Makefile in a tests/ directory was auto-generating a Kyuafile 1717 instead of providing an explicit one, this would prevent such 1718 Makefile from providing its own Kyuafile in the future during 1719 NO_CLEAN builds. This has been fixed in the Makefiles but manual 1720 intervention is needed to clean an objdir if you use NO_CLEAN: 1721 # find /usr/obj -name Kyuafile | xargs rm -f 1722 172320131213: 1724 The behavior of gss_pseudo_random() for the krb5 mechanism 1725 has changed, for applications requesting a longer random string 1726 than produced by the underlying enctype's pseudo-random() function. 1727 In particular, the random string produced from a session key of 1728 enctype aes256-cts-hmac-sha1-96 or aes256-cts-hmac-sha1-96 will 1729 be different at the 17th octet and later, after this change. 1730 The counter used in the PRF+ construction is now encoded as a 1731 big-endian integer in accordance with RFC 4402. 1732 __FreeBSD_version is bumped to 1100004. 1733 173420131108: 1735 The WITHOUT_ATF build knob has been removed and its functionality 1736 has been subsumed into the more generic WITHOUT_TESTS. If you were 1737 using the former to disable the build of the ATF libraries, you 1738 should change your settings to use the latter. 1739 174020131025: 1741 The default version of mtree is nmtree which is obtained from 1742 NetBSD. The output is generally the same, but may vary 1743 slightly. If you found you need identical output adding 1744 "-F freebsd9" to the command line should do the trick. For the 1745 time being, the old mtree is available as fmtree. 1746 174720131014: 1748 libbsdyml has been renamed to libyaml and moved to /usr/lib/private. 1749 This will break ports-mgmt/pkg. Rebuild the port, or upgrade to pkg 1750 1.1.4_8 and verify bsdyml not linked in, before running "make 1751 delete-old-libs": 1752 # make -C /usr/ports/ports-mgmt/pkg build deinstall install clean 1753 or 1754 # pkg install pkg; ldd /usr/local/sbin/pkg | grep bsdyml 1755 175620131010: 1757 The stable/10 branch has been created in subversion from head 1758 revision r256279. 1759 1760COMMON ITEMS: 1761 1762 General Notes 1763 ------------- 1764 Avoid using make -j when upgrading. While generally safe, there are 1765 sometimes problems using -j to upgrade. If your upgrade fails with 1766 -j, please try again without -j. From time to time in the past there 1767 have been problems using -j with buildworld and/or installworld. This 1768 is especially true when upgrading between "distant" versions (eg one 1769 that cross a major release boundary or several minor releases, or when 1770 several months have passed on the -current branch). 1771 1772 Sometimes, obscure build problems are the result of environment 1773 poisoning. This can happen because the make utility reads its 1774 environment when searching for values for global variables. To run 1775 your build attempts in an "environmental clean room", prefix all make 1776 commands with 'env -i '. See the env(1) manual page for more details. 1777 1778 When upgrading from one major version to another it is generally best to 1779 upgrade to the latest code in the currently installed branch first, then 1780 do an upgrade to the new branch. This is the best-tested upgrade path, 1781 and has the highest probability of being successful. Please try this 1782 approach if you encounter problems with a major version upgrade. Since 1783 the stable 4.x branch point, one has generally been able to upgrade from 1784 anywhere in the most recent stable branch to head / current (or even the 1785 last couple of stable branches). See the top of this file when there's 1786 an exception. 1787 1788 When upgrading a live system, having a root shell around before 1789 installing anything can help undo problems. Not having a root shell 1790 around can lead to problems if pam has changed too much from your 1791 starting point to allow continued authentication after the upgrade. 1792 1793 This file should be read as a log of events. When a later event changes 1794 information of a prior event, the prior event should not be deleted. 1795 Instead, a pointer to the entry with the new information should be 1796 placed in the old entry. Readers of this file should also sanity check 1797 older entries before relying on them blindly. Authors of new entries 1798 should write them with this in mind. 1799 1800 ZFS notes 1801 --------- 1802 When upgrading the boot ZFS pool to a new version, always follow 1803 these two steps: 1804 1805 1.) recompile and reinstall the ZFS boot loader and boot block 1806 (this is part of "make buildworld" and "make installworld") 1807 1808 2.) update the ZFS boot block on your boot drive 1809 1810 The following example updates the ZFS boot block on the first 1811 partition (freebsd-boot) of a GPT partitioned drive ada0: 1812 "gpart bootcode -p /boot/gptzfsboot -i 1 ada0" 1813 1814 Non-boot pools do not need these updates. 1815 1816 To build a kernel 1817 ----------------- 1818 If you are updating from a prior version of FreeBSD (even one just 1819 a few days old), you should follow this procedure. It is the most 1820 failsafe as it uses a /usr/obj tree with a fresh mini-buildworld, 1821 1822 make kernel-toolchain 1823 make -DALWAYS_CHECK_MAKE buildkernel KERNCONF=YOUR_KERNEL_HERE 1824 make -DALWAYS_CHECK_MAKE installkernel KERNCONF=YOUR_KERNEL_HERE 1825 1826 To test a kernel once 1827 --------------------- 1828 If you just want to boot a kernel once (because you are not sure 1829 if it works, or if you want to boot a known bad kernel to provide 1830 debugging information) run 1831 make installkernel KERNCONF=YOUR_KERNEL_HERE KODIR=/boot/testkernel 1832 nextboot -k testkernel 1833 1834 To rebuild everything and install it on the current system. 1835 ----------------------------------------------------------- 1836 # Note: sometimes if you are running current you gotta do more than 1837 # is listed here if you are upgrading from a really old current. 1838 1839 <make sure you have good level 0 dumps> 1840 make buildworld 1841 make buildkernel KERNCONF=YOUR_KERNEL_HERE 1842 make installkernel KERNCONF=YOUR_KERNEL_HERE 1843 [1] 1844 <reboot in single user> [3] 1845 mergemaster -Fp [5] 1846 make installworld 1847 mergemaster -Fi [4] 1848 make delete-old [6] 1849 <reboot> 1850 1851 To cross-install current onto a separate partition 1852 -------------------------------------------------- 1853 # In this approach we use a separate partition to hold 1854 # current's root, 'usr', and 'var' directories. A partition 1855 # holding "/", "/usr" and "/var" should be about 2GB in 1856 # size. 1857 1858 <make sure you have good level 0 dumps> 1859 <boot into -stable> 1860 make buildworld 1861 make buildkernel KERNCONF=YOUR_KERNEL_HERE 1862 <maybe newfs current's root partition> 1863 <mount current's root partition on directory ${CURRENT_ROOT}> 1864 make installworld DESTDIR=${CURRENT_ROOT} -DDB_FROM_SRC 1865 make distribution DESTDIR=${CURRENT_ROOT} # if newfs'd 1866 make installkernel KERNCONF=YOUR_KERNEL_HERE DESTDIR=${CURRENT_ROOT} 1867 cp /etc/fstab ${CURRENT_ROOT}/etc/fstab # if newfs'd 1868 <edit ${CURRENT_ROOT}/etc/fstab to mount "/" from the correct partition> 1869 <reboot into current> 1870 <do a "native" rebuild/install as described in the previous section> 1871 <maybe install compatibility libraries from ports/misc/compat*> 1872 <reboot> 1873 1874 1875 To upgrade in-place from stable to current 1876 ---------------------------------------------- 1877 <make sure you have good level 0 dumps> 1878 make buildworld [9] 1879 make buildkernel KERNCONF=YOUR_KERNEL_HERE [8] 1880 make installkernel KERNCONF=YOUR_KERNEL_HERE 1881 [1] 1882 <reboot in single user> [3] 1883 mergemaster -Fp [5] 1884 make installworld 1885 mergemaster -Fi [4] 1886 make delete-old [6] 1887 <reboot> 1888 1889 Make sure that you've read the UPDATING file to understand the 1890 tweaks to various things you need. At this point in the life 1891 cycle of current, things change often and you are on your own 1892 to cope. The defaults can also change, so please read ALL of 1893 the UPDATING entries. 1894 1895 Also, if you are tracking -current, you must be subscribed to 1896 freebsd-current@freebsd.org. Make sure that before you update 1897 your sources that you have read and understood all the recent 1898 messages there. If in doubt, please track -stable which has 1899 much fewer pitfalls. 1900 1901 [1] If you have third party modules, such as vmware, you 1902 should disable them at this point so they don't crash your 1903 system on reboot. 1904 1905 [3] From the bootblocks, boot -s, and then do 1906 fsck -p 1907 mount -u / 1908 mount -a 1909 sh /etc/rc.d/zfs start # mount zfs filesystem, if needed 1910 cd src # full path to source 1911 adjkerntz -i # if CMOS is wall time 1912 Also, when doing a major release upgrade, it is required that 1913 you boot into single user mode to do the installworld. 1914 1915 [4] Note: This step is non-optional. Failure to do this step 1916 can result in a significant reduction in the functionality of the 1917 system. Attempting to do it by hand is not recommended and those 1918 that pursue this avenue should read this file carefully, as well 1919 as the archives of freebsd-current and freebsd-hackers mailing lists 1920 for potential gotchas. The -U option is also useful to consider. 1921 See mergemaster(8) for more information. 1922 1923 [5] Usually this step is a no-op. However, from time to time 1924 you may need to do this if you get unknown user in the following 1925 step. It never hurts to do it all the time. You may need to 1926 install a new mergemaster (cd src/usr.sbin/mergemaster && make 1927 install) after the buildworld before this step if you last updated 1928 from current before 20130425 or from -stable before 20130430. 1929 1930 [6] This only deletes old files and directories. Old libraries 1931 can be deleted by "make delete-old-libs", but you have to make 1932 sure that no program is using those libraries anymore. 1933 1934 [8] The new kernel must be able to run existing binaries used by an 1935 installworld. When upgrading across major versions, the new kernel's 1936 configuration must include the correct COMPAT_FREEBSD<n> option for 1937 existing binaries (e.g. COMPAT_FREEBSD11 to run 11.x binaries). Failure 1938 to do so may leave you with a system that is hard to boot to recover. A 1939 GENERIC kernel will include suitable compatibility options to run 1940 binaries from older branches. Note that the ability to run binaries 1941 from unsupported branches is not guaranteed. 1942 1943 Make sure that you merge any new devices from GENERIC since the 1944 last time you updated your kernel config file. Options also 1945 change over time, so you may need to adjust your custom kernels 1946 for these as well. 1947 1948 [9] If CPUTYPE is defined in your /etc/make.conf, make sure to use the 1949 "?=" instead of the "=" assignment operator, so that buildworld can 1950 override the CPUTYPE if it needs to. 1951 1952 MAKEOBJDIRPREFIX must be defined in an environment variable, and 1953 not on the command line, or in /etc/make.conf. buildworld will 1954 warn if it is improperly defined. 1955FORMAT: 1956 1957This file contains a list, in reverse chronological order, of major 1958breakages in tracking -current. It is not guaranteed to be a complete 1959list of such breakages, and only contains entries since September 23, 2011. 1960If you need to see UPDATING entries from before that date, you will need 1961to fetch an UPDATING file from an older FreeBSD release. 1962 1963Copyright information: 1964 1965Copyright 1998-2009 M.
