UPDATING revision 336409
1Updating 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 1920180714: 20 Clang, llvm, lld, lldb, compiler-rt and libc++ have been upgraded to 21 6.0.1. Please see the 20141231 entry below for information about 22 prerequisites and upgrading, if you are not already using clang 3.5.0 23 or higher. 24 2520180601: 26 The releng/11.2 branch has been created from stable/11@r334458. 27 2820180504: 29 The tz database (tzdb) has been updated to 2018e. This version more 30 correctly models time stamps in time zones with negative DST such as 31 Europe/Dublin (from 1971 on), Europe/Prague (1946/7), and 32 Africa/Windhoek (1994/2017). This does not affect the UT offsets, only 33 time zone abbreviations and the tm_isdst flag. 34 3520180409: 36 The use of RSS hash from the network card aka flowid has been 37 disabled by default for lagg(4) as it's currently incompatible with 38 the lacp and loadbalance protocols. 39 40 This can be re-enabled by setting the following in loader.conf: 41 net.link.lagg.default_use_flowid="1" 42 4320180331: 44 Clang, llvm, lld, lldb, compiler-rt and libc++ have been upgraded to 45 6.0.0. Please see the 20141231 entry below for information about 46 prerequisites and upgrading, if you are not already using clang 3.5.0 47 or higher. 48 4920180211: 50 The LOADER_FIREWIRE_SUPPORT build variable as been renamed to 51 WITH/OUT_LOADER_FIREWIRE. LOADER_{NO_,}GELI_SUPPORT has been renamed 52 to WITH/OUT_LOADER_GELI. 53 5420180210: 55 The geli password typed at boot is now hidden. To restore the previous 56 behavior, see geli(8) for configuration options. 57 58 The SW_WATCHDOG option is no longer necessary to enable the 59 hardclock-based software watchdog if no hardware watchdog is 60 configured. As before, SW_WATCHDOG will cause the software 61 watchdog to be enabled even if a hardware watchdog is configured. 62 6320180108: 64 lint(1) binaries and library are no longer built by default. To 65 enable building them, define WITH_LINT in src.conf. If you are using 66 a FreeBSD 12 or later system to build 11-stable, you may need to 67 install a lint(1) binary to use WITH_LINT. 68 6920171003: 70 When building multiple kernels using KERNCONF, non-existent KERNCONF 71 files will produce an error and buildkernel will fail. Previously 72 missing KERNCONF files silently failed giving no indication as to 73 why, only to subsequently discover during installkernel that the 74 desired kernel was never built in the first place. 75 7620170926: 77 Clang, llvm, lldb, compiler-rt and libc++ have been upgraded to 5.0.0. 78 Please see the 20141231 entry below for information about prerequisites 79 and upgrading, if you are not already using clang 3.5.0 or higher. 80 8120170822: 82 Since the switch to GPT disk labels, fsck for UFS/FFS has been 83 unable to automatically find alternate superblocks. As of r322806, 84 the information needed to find alternate superblocks has been 85 moved to the end of the area reserved for the boot block. 86 Filesystems created with a newfs of this vintage or later 87 will create the recovery information. If you have a filesystem 88 created prior to this change and wish to have a recovery block 89 created for your filesystem, you can do so by running fsck in 90 forground mode (i.e., do not use the -p or -y options). As it 91 starts, fsck will ask ``SAVE DATA TO FIND ALTERNATE SUPERBLOCKS'' 92 to which you should answer yes. 93 9420170629: 95 The releng/11.1 branch has been created from stable/11@r320475. 96 9720170518: 98 arm64 builds now use the base system LLD 4.0.0 linker by default, 99 instead of requiring that the aarch64-binutils port or package be 100 installed. To continue using aarch64-binutils, set 101 CROSS_BINUTILS_PREFIX=/usr/local/aarch64-freebsd/bin . 102 10320170529: 104 The ctl.ko module no longer implements the iSCSI target frontend: 105 cfiscsi.ko does instead. 106 107 If building cfiscsi.ko as a kernel module, the module can be loaded 108 via one of the following methods: 109 - `cfiscsi_load="YES"` in loader.conf(5). 110 - Add `cfiscsi` to `$kld_list` in rc.conf(5). 111 - ctladm(8)/ctld(8), when compiled with iSCSI support 112 (`WITH_ISCSI=yes` in src.conf(5)) 113 114 Please see cfiscsi(4) for more details. 115 11620170511: 117 The mmcsd.ko module now additionally depends on geom_flashmap.ko. 118 Also, mmc.ko and mmcsd.ko need to be a matching pair built from the 119 same source (previously, the dependency of mmcsd.ko on mmc.ko was 120 missing, but mmcsd.ko now will refuse to load if it is incompatible 121 with mmc.ko). 122 12320170414: 124 Binds and sends to the loopback addresses, IPv6 and IPv4, will now 125 use any explicitly assigned loopback address available in the jail 126 instead of using the first assigned address of the jail. 127 12820170413: 129 As of r316810 for ipfilter, keep frags is no longer assumed when 130 keep state is specified in a rule. r316810 aligns ipfilter with 131 documentation in man pages separating keep frags from keep state. 132 This allows keep state to specified without forcing keep frags 133 and allows keep frags to be specified independently of keep state. 134 To maintain previous behaviour, also specify keep frags with 135 keep state (as documented in ipf.conf.5). 136 13720170402: 138 Clang, llvm, lldb, compiler-rt and libc++ have been upgraded to 4.0.0. 139 Please see the 20141231 entry below for information about prerequisites 140 and upgrading, if you are not already using clang 3.5.0 or higher. 141 14220170323: 143 The code that provides support for ZFS .zfs/ directory functionality 144 has been reimplemented. It's not possible now to create a snapshot 145 by mkdir under .zfs/snapshot/. That should be the only user visible 146 change. 147 14820170319: 149 Many changes in the IPsec code have been merged from the FreeBSD-CURRENT 150 branch. The IPSEC_FILTERTUNNEL kernel option is removed in favour of 151 corresponding sysctl. The IPSEC_NAT_T kernel option is also removed, 152 and now NAT-T is supported by default. Security associations now use 153 the single namespace for SPI allocation, so if you use several manually 154 configured security associations with the same SPI, this configuration 155 needs modification. 156 15720161217: 158 Clang, llvm, lldb, compiler-rt and libc++ have been upgraded to 3.9.1. 159 Please see the 20141231 entry below for information about prerequisites 160 and upgrading, if you are not already using clang 3.5.0 or higher. 161 16220161124: 163 Clang, llvm, lldb, compiler-rt and libc++ have been upgraded to 3.9.0. 164 Please see the 20141231 entry below for information about prerequisites 165 and upgrading, if you are not already using clang 3.5.0 or higher. 166 16720161119: 168 The layout of the pmap structure has changed for powerpc to put the pmap 169 statistics at the front for all CPU variations. libkvm(3) and all tools 170 that link against it need to be recompiled. 171 17220161030: 173 isl(4) and cyapa(4) drivers now require a new driver, 174 chromebook_platform(4), to work properly on Chromebook-class hardware. 175 On other types of hardware the drivers may need to be configured using 176 device hints. Please see the corresponding manual pages for details. 177 17820161210: 179 Relocatable object files with the extension of .So have been renamed 180 to use an extension of .pico instead. The purpose of this change is 181 to avoid a name clash with shared libraries on case-insensitive file 182 systems. On those file systems, foo.So is the same file as foo.so. 183 18420160811: 185 The releng/11.0 branch has been created from stable/11@r303970. 186 18720160708: 188 The stable/11 branch has been created from head@r302406. 189 19020160622: 191 The libc stub for the pipe(2) system call has been replaced with 192 a wrapper that calls the pipe2(2) system call and the pipe(2) 193 system call is now only implemented by the kernels that include 194 "options COMPAT_FREEBSD10" in their config file (this is the 195 default). Users should ensure that this option is enabled in 196 their kernel or upgrade userspace to r302092 before upgrading their 197 kernel. 198 19920160527: 200 CAM will now strip leading spaces from SCSI disks' serial numbers. 201 This will effect users who create UFS filesystems on SCSI disks using 202 those disk's diskid device nodes. For example, if /etc/fstab 203 previously contained a line like 204 "/dev/diskid/DISK-%20%20%20%20%20%20%20ABCDEFG0123456", you should 205 change it to "/dev/diskid/DISK-ABCDEFG0123456". Users of geom 206 transforms like gmirror may also be affected. ZFS users should 207 generally be fine. 208 20920160523: 210 The bitstring(3) API has been updated with new functionality and 211 improved performance. But it is binary-incompatible with the old API. 212 Objects built with the new headers may not be linked against objects 213 built with the old headers. 214 21520160520: 216 The brk and sbrk functions have been removed from libc on arm64. 217 Binutils from ports has been updated to not link to these 218 functions and should be updated to the latest version before 219 installing a new libc. 220 22120160517: 222 The armv6 port now defaults to hard float ABI. Limited support 223 for running both hardfloat and soft float on the same system 224 is available using the libraries installed with -DWITH_LIBSOFT. 225 This has only been tested as an upgrade path for installworld 226 and packages may fail or need manual intervention to run. New 227 packages will be needed. 228 229 To update an existing self-hosted armv6hf system, you must add 230 TARGET_ARCH=armv6 on the make command line for both the build 231 and the install steps. 232 23320160510: 234 Kernel modules compiled outside of a kernel build now default to 235 installing to /boot/modules instead of /boot/kernel. Many kernel 236 modules built this way (such as those in ports) already overrode 237 KMODDIR explicitly to install into /boot/modules. However, 238 manually building and installing a module from /sys/modules will 239 now install to /boot/modules instead of /boot/kernel. 240 24120160414: 242 The CAM I/O scheduler has been committed to the kernel. There should be 243 no user visible impact. This does enable NCQ Trim on ada SSDs. While the 244 list of known rogues that claim support for this but actually corrupt 245 data is believed to be complete, be on the lookout for data 246 corruption. The known rogue list is believed to be complete: 247 248 o Crucial MX100, M550 drives with MU01 firmware. 249 o Micron M510 and M550 drives with MU01 firmware. 250 o Micron M500 prior to MU07 firmware 251 o Samsung 830, 840, and 850 all firmwares 252 o FCCT M500 all firmwares 253 254 Crucial has firmware http://www.crucial.com/usa/en/support-ssd-firmware 255 with working NCQ TRIM. For Micron branded drives, see your sales rep for 256 updated firmware. Black listed drives will work correctly because these 257 drives work correctly so long as no NCQ TRIMs are sent to them. Given 258 this list is the same as found in Linux, it's believed there are no 259 other rogues in the market place. All other models from the above 260 vendors work. 261 262 To be safe, if you are at all concerned, you can quirk each of your 263 drives to prevent NCQ from being sent by setting: 264 kern.cam.ada.X.quirks="0x2" 265 in loader.conf. If the drive requires the 4k sector quirk, set the 266 quirks entry to 0x3. 267 26820160330: 269 The FAST_DEPEND build option has been removed and its functionality is 270 now the one true way. The old mkdep(1) style of 'make depend' has 271 been removed. See 20160311 for further details. 272 27320160317: 274 Resource range types have grown from unsigned long to uintmax_t. All 275 drivers, and anything using libdevinfo, need to be recompiled. 276 27720160311: 278 WITH_FAST_DEPEND is now enabled by default for in-tree and out-of-tree 279 builds. It no longer runs mkdep(1) during 'make depend', and the 280 'make depend' stage can safely be skipped now as it is auto ran 281 when building 'make all' and will generate all SRCS and DPSRCS before 282 building anything else. Dependencies are gathered at compile time with 283 -MF flags kept in separate .depend files per object file. Users should 284 run 'make cleandepend' once if using -DNO_CLEAN to clean out older 285 stale .depend files. 286 28720160306: 288 On amd64, clang 3.8.0 can now insert sections of type AMD64_UNWIND into 289 kernel modules. Therefore, if you load any kernel modules at boot time, 290 please install the boot loaders after you install the kernel, but before 291 rebooting, e.g.: 292 293 make buildworld 294 make kernel KERNCONF=YOUR_KERNEL_HERE 295 make -C sys/boot install 296 <reboot in single user> 297 298 Then follow the usual steps, described in the General Notes section, 299 below. 300 30120160305: 302 Clang, llvm, lldb and compiler-rt have been upgraded to 3.8.0. Please 303 see the 20141231 entry below for information about prerequisites and 304 upgrading, if you are not already using clang 3.5.0 or higher. 305 30620160301: 307 The AIO subsystem is now a standard part of the kernel. The 308 VFS_AIO kernel option and aio.ko kernel module have been removed. 309 Due to stability concerns, asynchronous I/O requests are only 310 permitted on sockets and raw disks by default. To enable 311 asynchronous I/O requests on all file types, set the 312 vfs.aio.enable_unsafe sysctl to a non-zero value. 313 31420160226: 315 The ELF object manipulation tool objcopy is now provided by the 316 ELF Tool Chain project rather than by GNU binutils. It should be a 317 drop-in replacement, with the addition of arm64 support. The 318 (temporary) src.conf knob WITHOUT_ELFCOPY_AS_OBJCOPY knob may be set 319 to obtain the GNU version if necessary. 320 32120160129: 322 Building ZFS pools on top of zvols is prohibited by default. That 323 feature has never worked safely; it's always been prone to deadlocks. 324 Using a zvol as the backing store for a VM guest's virtual disk will 325 still work, even if the guest is using ZFS. Legacy behavior can be 326 restored by setting vfs.zfs.vol.recursive=1. 327 32820160119: 329 The NONE and HPN patches has been removed from OpenSSH. They are 330 still available in the security/openssh-portable port. 331 33220160113: 333 With the addition of ypldap(8), a new _ypldap user is now required 334 during installworld. "mergemaster -p" can be used to add the user 335 prior to installworld, as documented in the handbook. 336 33720151216: 338 The tftp loader (pxeboot) now uses the option root-path directive. As a 339 consequence it no longer looks for a pxeboot.4th file on the tftp 340 server. Instead it uses the regular /boot infrastructure as with the 341 other loaders. 342 34320151211: 344 The code to start recording plug and play data into the modules has 345 been committed. While the old tools will properly build a new kernel, 346 a number of warnings about "unknown metadata record 4" will be produced 347 for an older kldxref. To avoid such warnings, make sure to rebuild 348 the kernel toolchain (or world). Make sure that you have r292078 or 349 later when trying to build 292077 or later before rebuilding. 350 35120151207: 352 Debug data files are now built by default with 'make buildworld' and 353 installed with 'make installworld'. This facilitates debugging but 354 requires more disk space both during the build and for the installed 355 world. Debug files may be disabled by setting WITHOUT_DEBUG_FILES=yes 356 in src.conf(5). 357 35820151130: 359 r291527 changed the internal interface between the nfsd.ko and 360 nfscommon.ko modules. As such, they must both be upgraded to-gether. 361 __FreeBSD_version has been bumped because of this. 362 36320151108: 364 Add support for unicode collation strings leads to a change of 365 order of files listed by ls(1) for example. To get back to the old 366 behaviour, set LC_COLLATE environment variable to "C". 367 368 Databases administrators will need to reindex their databases given 369 collation results will be different. 370 371 Due to a bug in install(1) it is recommended to remove the ancient 372 locales before running make installworld. 373 374 rm -rf /usr/share/locale/* 375 37620151030: 377 The OpenSSL has been upgraded to 1.0.2d. Any binaries requiring 378 libcrypto.so.7 or libssl.so.7 must be recompiled. 379 38020151020: 381 Qlogic 24xx/25xx firmware images were updated from 5.5.0 to 7.3.0. 382 Kernel modules isp_2400_multi and isp_2500_multi were removed and 383 should be replaced with isp_2400 and isp_2500 modules respectively. 384 38520151017: 386 The build previously allowed using 'make -n' to not recurse into 387 sub-directories while showing what commands would be executed, and 388 'make -n -n' to recursively show commands. Now 'make -n' will recurse 389 and 'make -N' will not. 390 39120151012: 392 If you specify SENDMAIL_MC or SENDMAIL_CF in make.conf, mergemaster 393 and etcupdate will now use this file. A custom sendmail.cf is now 394 updated via this mechanism rather than via installworld. If you had 395 excluded sendmail.cf in mergemaster.rc or etcupdate.conf, you may 396 want to remove the exclusion or change it to "always install". 397 /etc/mail/sendmail.cf is now managed the same way regardless of 398 whether SENDMAIL_MC/SENDMAIL_CF is used. If you are not using 399 SENDMAIL_MC/SENDMAIL_CF there should be no change in behavior. 400 40120151011: 402 Compatibility shims for legacy ATA device names have been removed. 403 It includes ATA_STATIC_ID kernel option, kern.cam.ada.legacy_aliases 404 and kern.geom.raid.legacy_aliases loader tunables, kern.devalias.* 405 environment variables, /dev/ad* and /dev/ar* symbolic links. 406 40720151006: 408 Clang, llvm, lldb, compiler-rt and libc++ have been upgraded to 3.7.0. 409 Please see the 20141231 entry below for information about prerequisites 410 and upgrading, if you are not already using clang 3.5.0 or higher. 411 41220150924: 413 Kernel debug files have been moved to /usr/lib/debug/boot/kernel/, 414 and renamed from .symbols to .debug. This reduces the size requirements 415 on the boot partition or file system and provides consistency with 416 userland debug files. 417 418 When using the supported kernel installation method the 419 /usr/lib/debug/boot/kernel directory will be renamed (to kernel.old) 420 as is done with /boot/kernel. 421 422 Developers wishing to maintain the historical behavior of installing 423 debug files in /boot/kernel/ can set KERN_DEBUGDIR="" in src.conf(5). 424 42520150827: 426 The wireless drivers had undergone changes that remove the 'parent 427 interface' from the ifconfig -l output. The rc.d network scripts 428 used to check presence of a parent interface in the list, so old 429 scripts would fail to start wireless networking. Thus, etcupdate(3) 430 or mergemaster(8) run is required after kernel update, to update your 431 rc.d scripts in /etc. 432 43320150827: 434 pf no longer supports 'scrub fragment crop' or 'scrub fragment drop-ovl' 435 These configurations are now automatically interpreted as 436 'scrub fragment reassemble'. 437 43820150817: 439 Kernel-loadable modules for the random(4) device are back. To use 440 them, the kernel must have 441 442 device random 443 options RANDOM_LOADABLE 444 445 kldload(8) can then be used to load random_fortuna.ko 446 or random_yarrow.ko. Please note that due to the indirect 447 function calls that the loadable modules need to provide, 448 the build-in variants will be slightly more efficient. 449 450 The random(4) kernel option RANDOM_DUMMY has been retired due to 451 unpopularity. It was not all that useful anyway. 452 45320150813: 454 The WITHOUT_ELFTOOLCHAIN_TOOLS src.conf(5) knob has been retired. 455 Control over building the ELF Tool Chain tools is now provided by 456 the WITHOUT_TOOLCHAIN knob. 457 45820150810: 459 The polarity of Pulse Per Second (PPS) capture events with the 460 uart(4) driver has been corrected. Prior to this change the PPS 461 "assert" event corresponded to the trailing edge of a positive PPS 462 pulse and the "clear" event was the leading edge of the next pulse. 463 464 As the width of a PPS pulse in a typical GPS receiver is on the 465 order of 1 millisecond, most users will not notice any significant 466 difference with this change. 467 468 Anyone who has compensated for the historical polarity reversal by 469 configuring a negative offset equal to the pulse width will need to 470 remove that workaround. 471 47220150809: 473 The default group assigned to /dev/dri entries has been changed 474 from 'wheel' to 'video' with the id of '44'. If you want to have 475 access to the dri devices please add yourself to the video group 476 with: 477 478 # pw groupmod video -m $USER 479 48020150806: 481 The menu.rc and loader.rc files will now be replaced during 482 upgrades. Please migrate local changes to menu.rc.local and 483 loader.rc.local instead. 484 48520150805: 486 GNU Binutils versions of addr2line, c++filt, nm, readelf, size, 487 strings and strip have been removed. The src.conf(5) knob 488 WITHOUT_ELFTOOLCHAIN_TOOLS no longer provides the binutils tools. 489 49020150728: 491 As ZFS requires more kernel stack pages than is the default on some 492 architectures e.g. i386, it now warns if KSTACK_PAGES is less than 493 ZFS_MIN_KSTACK_PAGES (which is 4 at the time of writing). 494 495 Please consider using 'options KSTACK_PAGES=X' where X is greater 496 than or equal to ZFS_MIN_KSTACK_PAGES i.e. 4 in such configurations. 497 49820150706: 499 sendmail has been updated to 8.15.2. Starting with FreeBSD 11.0 500 and sendmail 8.15, sendmail uses uncompressed IPv6 addresses by 501 default, i.e., they will not contain "::". For example, instead 502 of ::1, it will be 0:0:0:0:0:0:0:1. This permits a zero subnet 503 to have a more specific match, such as different map entries for 504 IPv6:0:0 vs IPv6:0. This change requires that configuration 505 data (including maps, files, classes, custom ruleset, etc.) must 506 use the same format, so make certain such configuration data is 507 upgrading. As a very simple check search for patterns like 508 'IPv6:[0-9a-fA-F:]*::' and 'IPv6::'. To return to the old 509 behavior, set the m4 option confUSE_COMPRESSED_IPV6_ADDRESSES or 510 the cf option UseCompressedIPv6Addresses. 511 51220150630: 513 The default kernel entropy-processing algorithm is now 514 Fortuna, replacing Yarrow. 515 516 Assuming you have 'device random' in your kernel config 517 file, the configurations allow a kernel option to override 518 this default. You may choose *ONE* of: 519 520 options RANDOM_YARROW # Legacy /dev/random algorithm. 521 options RANDOM_DUMMY # Blocking-only driver. 522 523 If you have neither, you get Fortuna. For most people, 524 read no further, Fortuna will give a /dev/random that works 525 like it always used to, and the difference will be irrelevant. 526 527 If you remove 'device random', you get *NO* kernel-processed 528 entropy at all. This may be acceptable to folks building 529 embedded systems, but has complications. Carry on reading, 530 and it is assumed you know what you need. 531 532 *PLEASE* read random(4) and random(9) if you are in the 533 habit of tweaking kernel configs, and/or if you are a member 534 of the embedded community, wanting specific and not-usual 535 behaviour from your security subsystems. 536 537 NOTE!! If you use RANDOM_DUMMY and/or have no 'device 538 random', you will NOT have a functioning /dev/random, and 539 many cryptographic features will not work, including SSH. 540 You may also find strange behaviour from the random(3) set 541 of library functions, in particular sranddev(3), srandomdev(3) 542 and arc4random(3). The reason for this is that the KERN_ARND 543 sysctl only returns entropy if it thinks it has some to 544 share, and with RANDOM_DUMMY or no 'device random' this 545 will never happen. 546 54720150623: 548 An additional fix for the issue described in the 20150614 sendmail 549 entry below has been been committed in revision 284717. 550 55120150616: 552 FreeBSD's old make (fmake) has been removed from the system. It is 553 available as the devel/fmake port or via pkg install fmake. 554 55520150615: 556 The fix for the issue described in the 20150614 sendmail entry 557 below has been been committed in revision 284436. The work 558 around described in that entry is no longer needed unless the 559 default setting is overridden by a confDH_PARAMETERS configuration 560 setting of '5' or pointing to a 512 bit DH parameter file. 561 56220150614: 563 ALLOW_DEPRECATED_ATF_TOOLS/ATFFILE support has been removed from 564 atf.test.mk (included from bsd.test.mk). Please upgrade devel/atf 565 and devel/kyua to version 0.20+ and adjust any calling code to work 566 with Kyuafile and kyua. 567 56820150614: 569 The import of openssl to address the FreeBSD-SA-15:10.openssl 570 security advisory includes a change which rejects handshakes 571 with DH parameters below 768 bits. sendmail releases prior 572 to 8.15.2 (not yet released), defaulted to a 512 bit 573 DH parameter setting for client connections. To work around 574 this interoperability, sendmail can be configured to use a 575 2048 bit DH parameter by: 576 577 1. Edit /etc/mail/`hostname`.mc 578 2. If a setting for confDH_PARAMETERS does not exist or 579 exists and is set to a string beginning with '5', 580 replace it with '2'. 581 3. If a setting for confDH_PARAMETERS exists and is set to 582 a file path, create a new file with: 583 openssl dhparam -out /path/to/file 2048 584 4. Rebuild the .cf file: 585 cd /etc/mail/; make; make install 586 5. Restart sendmail: 587 cd /etc/mail/; make restart 588 589 A sendmail patch is coming, at which time this file will be 590 updated. 591 59220150604: 593 Generation of legacy formatted entries have been disabled by default 594 in pwd_mkdb(8), as all base system consumers of the legacy formatted 595 entries were converted to use the new format by default when the new, 596 machine independent format have been added and supported since FreeBSD 597 5.x. 598 599 Please see the pwd_mkdb(8) manual page for further details. 600 60120150525: 602 Clang and llvm have been upgraded to 3.6.1 release. Please see the 603 20141231 entry below for information about prerequisites and upgrading, 604 if you are not already using 3.5.0 or higher. 605 60620150521: 607 TI platform code switched to using vendor DTS files and this update 608 may break existing systems running on Beaglebone, Beaglebone Black, 609 and Pandaboard: 610 611 - dtb files should be regenerated/reinstalled. Filenames are the 612 same but content is different now 613 - GPIO addressing was changed, now each GPIO bank (32 pins per bank) 614 has its own /dev/gpiocX device, e.g. pin 121 on /dev/gpioc0 in old 615 addressing scheme is now pin 25 on /dev/gpioc3. 616 - Pandaboard: /etc/ttys should be updated, serial console device is 617 now /dev/ttyu2, not /dev/ttyu0 618 61920150501: 620 soelim(1) from gnu/usr.bin/groff has been replaced by usr.bin/soelim. 621 If you need the GNU extension from groff soelim(1), install groff 622 from package: pkg install groff, or via ports: textproc/groff. 623 62420150423: 625 chmod, chflags, chown and chgrp now affect symlinks in -R mode as 626 defined in symlink(7); previously symlinks were silently ignored. 627 62820150415: 629 The const qualifier has been removed from iconv(3) to comply with 630 POSIX. The ports tree is aware of this from r384038 onwards. 631 63220150416: 633 Libraries specified by LIBADD in Makefiles must have a corresponding 634 DPADD_<lib> variable to ensure correct dependencies. This is now 635 enforced in src.libnames.mk. 636 63720150324: 638 From legacy ata(4) driver was removed support for SATA controllers 639 supported by more functional drivers ahci(4), siis(4) and mvs(4). 640 Kernel modules ataahci and ataadaptec were removed completely, 641 replaced by ahci and mvs modules respectively. 642 64320150315: 644 Clang, llvm and lldb have been upgraded to 3.6.0 release. Please see 645 the 20141231 entry below for information about prerequisites and 646 upgrading, if you are not already using 3.5.0 or higher. 647 64820150307: 649 The 32-bit PowerPC kernel has been changed to a position-independent 650 executable. This can only be booted with a version of loader(8) 651 newer than January 31, 2015, so make sure to update both world and 652 kernel before rebooting. 653 65420150217: 655 If you are running a -CURRENT kernel since r273872 (Oct 30th, 2014), 656 but before r278950, the RNG was not seeded properly. Immediately 657 upgrade the kernel to r278950 or later and regenerate any keys (e.g. 658 ssh keys or openssl keys) that were generated w/ a kernel from that 659 range. This does not affect programs that directly used /dev/random 660 or /dev/urandom. All userland uses of arc4random(3) are affected. 661 66220150210: 663 The autofs(4) ABI was changed in order to restore binary compatibility 664 with 10.1-RELEASE. The automountd(8) daemon needs to be rebuilt to work 665 with the new kernel. 666 66720150131: 668 The powerpc64 kernel has been changed to a position-independent 669 executable. This can only be booted with a new version of loader(8), 670 so make sure to update both world and kernel before rebooting. 671 67220150118: 673 Clang and llvm have been upgraded to 3.5.1 release. This is a bugfix 674 only release, no new features have been added. Please see the 20141231 675 entry below for information about prerequisites and upgrading, if you 676 are not already using 3.5.0. 677 67820150107: 679 ELF tools addr2line, elfcopy (strip), nm, size, and strings are now 680 taken from the ELF Tool Chain project rather than GNU binutils. They 681 should be drop-in replacements, with the addition of arm64 support. 682 The WITHOUT_ELFTOOLCHAIN_TOOLS= knob may be used to obtain the 683 binutils tools, if necessary. See 20150805 for updated information. 684 68520150105: 686 The default Unbound configuration now enables remote control 687 using a local socket. Users who have already enabled the 688 local_unbound service should regenerate their configuration 689 by running "service local_unbound setup" as root. 690 69120150102: 692 The GNU texinfo and GNU info pages have been removed. 693 To be able to view GNU info pages please install texinfo from ports. 694 69520141231: 696 Clang, llvm and lldb have been upgraded to 3.5.0 release. 697 698 As of this release, a prerequisite for building clang, llvm and lldb is 699 a C++11 capable compiler and C++11 standard library. This means that to 700 be able to successfully build the cross-tools stage of buildworld, with 701 clang as the bootstrap compiler, your system compiler or cross compiler 702 should either be clang 3.3 or later, or gcc 4.8 or later, and your 703 system C++ library should be libc++, or libdstdc++ from gcc 4.8 or 704 later. 705 706 On any standard FreeBSD 10.x or 11.x installation, where clang and 707 libc++ are on by default (that is, on x86 or arm), this should work out 708 of the box. 709 710 On 9.x installations where clang is enabled by default, e.g. on x86 and 711 powerpc, libc++ will not be enabled by default, so libc++ should be 712 built (with clang) and installed first. If both clang and libc++ are 713 missing, build clang first, then use it to build libc++. 714 715 On 8.x and earlier installations, upgrade to 9.x first, and then follow 716 the instructions for 9.x above. 717 718 Sparc64 and mips users are unaffected, as they still use gcc 4.2.1 by 719 default, and do not build clang. 720 721 Many embedded systems are resource constrained, and will not be able to 722 build clang in a reasonable time, or in some cases at all. In those 723 cases, cross building bootable systems on amd64 is a workaround. 724 725 This new version of clang introduces a number of new warnings, of which 726 the following are most likely to appear: 727 728 -Wabsolute-value 729 730 This warns in two cases, for both C and C++: 731 * When the code is trying to take the absolute value of an unsigned 732 quantity, which is effectively a no-op, and almost never what was 733 intended. The code should be fixed, if at all possible. If you are 734 sure that the unsigned quantity can be safely cast to signed, without 735 loss of information or undefined behavior, you can add an explicit 736 cast, or disable the warning. 737 738 * When the code is trying to take an absolute value, but the called 739 abs() variant is for the wrong type, which can lead to truncation. 740 If you want to disable the warning instead of fixing the code, please 741 make sure that truncation will not occur, or it might lead to unwanted 742 side-effects. 743 744 -Wtautological-undefined-compare and 745 -Wundefined-bool-conversion 746 747 These warn when C++ code is trying to compare 'this' against NULL, while 748 'this' should never be NULL in well-defined C++ code. However, there is 749 some legacy (pre C++11) code out there, which actively abuses this 750 feature, which was less strictly defined in previous C++ versions. 751 752 Squid and openjdk do this, for example. The warning can be turned off 753 for C++98 and earlier, but compiling the code in C++11 mode might result 754 in unexpected behavior; for example, the parts of the program that are 755 unreachable could be optimized away. 756 75720141222: 758 The old NFS client and server (kernel options NFSCLIENT, NFSSERVER) 759 kernel sources have been removed. The .h files remain, since some 760 utilities include them. This will need to be fixed later. 761 If "mount -t oldnfs ..." is attempted, it will fail. 762 If the "-o" option on mountd(8), nfsd(8) or nfsstat(1) is used, 763 the utilities will report errors. 764 76520141121: 766 The handling of LOCAL_LIB_DIRS has been altered to skip addition of 767 directories to top level SUBDIR variable when their parent 768 directory is included in LOCAL_DIRS. Users with build systems with 769 such hierarchies and without SUBDIR entries in the parent 770 directory Makefiles should add them or add the directories to 771 LOCAL_DIRS. 772 77320141109: 774 faith(4) and faithd(8) have been removed from the base system. Faith 775 has been obsolete for a very long time. 776 77720141104: 778 vt(4), the new console driver, is enabled by default. It brings 779 support for Unicode and double-width characters, as well as 780 support for UEFI and integration with the KMS kernel video 781 drivers. 782 783 You may need to update your console settings in /etc/rc.conf, 784 most probably the keymap. During boot, /etc/rc.d/syscons will 785 indicate what you need to do. 786 787 vt(4) still has issues and lacks some features compared to 788 syscons(4). See the wiki for up-to-date information: 789 https://wiki.freebsd.org/Newcons 790 791 If you want to keep using syscons(4), you can do so by adding 792 the following line to /boot/loader.conf: 793 kern.vty=sc 794 79520141102: 796 pjdfstest has been integrated into kyua as an opt-in test suite. 797 Please see share/doc/pjdfstest/README for more details on how to 798 execute it. 799 80020141009: 801 gperf has been removed from the base system for architectures 802 that use clang. Ports that require gperf will obtain it from the 803 devel/gperf port. 804 80520140923: 806 pjdfstest has been moved from tools/regression/pjdfstest to 807 contrib/pjdfstest . 808 80920140922: 810 At svn r271982, The default linux compat kernel ABI has been adjusted 811 to 2.6.18 in support of the linux-c6 compat ports infrastructure 812 update. If you wish to continue using the linux-f10 compat ports, 813 add compat.linux.osrelease=2.6.16 to your local sysctl.conf. Users are 814 encouraged to update their linux-compat packages to linux-c6 during 815 their next update cycle. 816 81720140729: 818 The ofwfb driver, used to provide a graphics console on PowerPC when 819 using vt(4), no longer allows mmap() of all physical memory. This 820 will prevent Xorg on PowerPC with some ATI graphics cards from 821 initializing properly unless x11-servers/xorg-server is updated to 822 1.12.4_8 or newer. 823 82420140723: 825 The xdev targets have been converted to using TARGET and 826 TARGET_ARCH instead of XDEV and XDEV_ARCH. 827 82820140719: 829 The default unbound configuration has been modified to address 830 issues with reverse lookups on networks that use private 831 address ranges. If you use the local_unbound service, run 832 "service local_unbound setup" as root to regenerate your 833 configuration, then "service local_unbound reload" to load the 834 new configuration. 835 83620140709: 837 The GNU texinfo and GNU info pages are not built and installed 838 anymore, WITH_INFO knob has been added to allow to built and install 839 them again. 840 UPDATE: see 20150102 entry on texinfo's removal 841 84220140708: 843 The GNU readline library is now an INTERNALLIB - that is, it is 844 statically linked into consumers (GDB and variants) in the base 845 system, and the shared library is no longer installed. The 846 devel/readline port is available for third party software that 847 requires readline. 848 84920140702: 850 The Itanium architecture (ia64) has been removed from the list of 851 known architectures. This is the first step in the removal of the 852 architecture. 853 85420140701: 855 Commit r268115 has added NFSv4.1 server support, merged from 856 projects/nfsv4.1-server. Since this includes changes to the 857 internal interfaces between the NFS related modules, a full 858 build of the kernel and modules will be necessary. 859 __FreeBSD_version has been bumped. 860 86120140629: 862 The WITHOUT_VT_SUPPORT kernel config knob has been renamed 863 WITHOUT_VT. (The other _SUPPORT knobs have a consistent meaning 864 which differs from the behaviour controlled by this knob.) 865 86620140619: 867 Maximal length of the serial number in CTL was increased from 16 to 868 64 chars, that breaks ABI. All CTL-related tools, such as ctladm 869 and ctld, need to be rebuilt to work with a new kernel. 870 87120140606: 872 The libatf-c and libatf-c++ major versions were downgraded to 0 and 873 1 respectively to match the upstream numbers. They were out of 874 sync because, when they were originally added to FreeBSD, the 875 upstream versions were not respected. These libraries are private 876 and not yet built by default, so renumbering them should be a 877 non-issue. However, unclean source trees will yield broken test 878 programs once the operator executes "make delete-old-libs" after a 879 "make installworld". 880 881 Additionally, the atf-sh binary was made private by moving it into 882 /usr/libexec/. Already-built shell test programs will keep the 883 path to the old binary so they will break after "make delete-old" 884 is run. 885 886 If you are using WITH_TESTS=yes (not the default), wipe the object 887 tree and rebuild from scratch to prevent spurious test failures. 888 This is only needed once: the misnumbered libraries and misplaced 889 binaries have been added to OptionalObsoleteFiles.inc so they will 890 be removed during a clean upgrade. 891 89220140512: 893 Clang and llvm have been upgraded to 3.4.1 release. 894 89520140508: 896 We bogusly installed src.opts.mk in /usr/share/mk. This file should 897 be removed to avoid issues in the future (and has been added to 898 ObsoleteFiles.inc). 899 90020140505: 901 /etc/src.conf now affects only builds of the FreeBSD src tree. In the 902 past, it affected all builds that used the bsd.*.mk files. The old 903 behavior was a bug, but people may have relied upon it. To get this 904 behavior back, you can .include /etc/src.conf from /etc/make.conf 905 (which is still global and isn't changed). This also changes the 906 behavior of incremental builds inside the tree of individual 907 directories. Set MAKESYSPATH to ".../share/mk" to do that. 908 Although this has survived make universe and some upgrade scenarios, 909 other upgrade scenarios may have broken. At least one form of 910 temporary breakage was fixed with MAKESYSPATH settings for buildworld 911 as well... In cases where MAKESYSPATH isn't working with this 912 setting, you'll need to set it to the full path to your tree. 913 914 One side effect of all this cleaning up is that bsd.compiler.mk 915 is no longer implicitly included by bsd.own.mk. If you wish to 916 use COMPILER_TYPE, you must now explicitly include bsd.compiler.mk 917 as well. 918 91920140430: 920 The lindev device has been removed since /dev/full has been made a 921 standard device. __FreeBSD_version has been bumped. 922 92320140424: 924 The knob WITHOUT_VI was added to the base system, which controls 925 building ex(1), vi(1), etc. Older releases of FreeBSD required ex(1) 926 in order to reorder files share/termcap and didn't build ex(1) as a 927 build tool, so building/installing with WITH_VI is highly advised for 928 build hosts for older releases. 929 930 This issue has been fixed in stable/9 and stable/10 in r277022 and 931 r276991, respectively. 932 93320140418: 934 The YES_HESIOD knob has been removed. It has been obsolete for 935 a decade. Please move to using WITH_HESIOD instead or your builds 936 will silently lack HESIOD. 937 93820140405: 939 The uart(4) driver has been changed with respect to its handling 940 of the low-level console. Previously the uart(4) driver prevented 941 any process from changing the baudrate or the CLOCAL and HUPCL 942 control flags. By removing the restrictions, operators can make 943 changes to the serial console port without having to reboot. 944 However, when getty(8) is started on the serial device that is 945 associated with the low-level console, a misconfigured terminal 946 line in /etc/ttys will now have a real impact. 947 Before upgrading the kernel, make sure that /etc/ttys has the 948 serial console device configured as 3wire without baudrate to 949 preserve the previous behaviour. E.g: 950 ttyu0 "/usr/libexec/getty 3wire" vt100 on secure 951 95220140306: 953 Support for libwrap (TCP wrappers) in rpcbind was disabled by default 954 to improve performance. To re-enable it, if needed, run rpcbind 955 with command line option -W. 956 95720140226: 958 Switched back to the GPL dtc compiler due to updates in the upstream 959 dts files not being supported by the BSDL dtc compiler. You will need 960 to rebuild your kernel toolchain to pick up the new compiler. Core dumps 961 may result while building dtb files during a kernel build if you fail 962 to do so. Set WITHOUT_GPL_DTC if you require the BSDL compiler. 963 96420140216: 965 Clang and llvm have been upgraded to 3.4 release. 966 96720140216: 968 The nve(4) driver has been removed. Please use the nfe(4) driver 969 for NVIDIA nForce MCP Ethernet adapters instead. 970 97120140212: 972 An ABI incompatibility crept into the libc++ 3.4 import in r261283. 973 This could cause certain C++ applications using shared libraries built 974 against the previous version of libc++ to crash. The incompatibility 975 has now been fixed, but any C++ applications or shared libraries built 976 between r261283 and r261801 should be recompiled. 977 97820140204: 979 OpenSSH will now ignore errors caused by kernel lacking of Capsicum 980 capability mode support. Please note that enabling the feature in 981 kernel is still highly recommended. 982 98320140131: 984 OpenSSH is now built with sandbox support, and will use sandbox as 985 the default privilege separation method. This requires Capsicum 986 capability mode support in kernel. 987 98820140128: 989 The libelf and libdwarf libraries have been updated to newer 990 versions from upstream. Shared library version numbers for 991 these two libraries were bumped. Any ports or binaries 992 requiring these two libraries should be recompiled. 993 __FreeBSD_version is bumped to 1100006. 994 99520140110: 996 If a Makefile in a tests/ directory was auto-generating a Kyuafile 997 instead of providing an explicit one, this would prevent such 998 Makefile from providing its own Kyuafile in the future during 999 NO_CLEAN builds. This has been fixed in the Makefiles but manual 1000 intervention is needed to clean an objdir if you use NO_CLEAN: 1001 # find /usr/obj -name Kyuafile | xargs rm -f 1002 100320131213: 1004 The behavior of gss_pseudo_random() for the krb5 mechanism 1005 has changed, for applications requesting a longer random string 1006 than produced by the underlying enctype's pseudo-random() function. 1007 In particular, the random string produced from a session key of 1008 enctype aes256-cts-hmac-sha1-96 or aes256-cts-hmac-sha1-96 will 1009 be different at the 17th octet and later, after this change. 1010 The counter used in the PRF+ construction is now encoded as a 1011 big-endian integer in accordance with RFC 4402. 1012 __FreeBSD_version is bumped to 1100004. 1013 101420131108: 1015 The WITHOUT_ATF build knob has been removed and its functionality 1016 has been subsumed into the more generic WITHOUT_TESTS. If you were 1017 using the former to disable the build of the ATF libraries, you 1018 should change your settings to use the latter. 1019 102020131025: 1021 The default version of mtree is nmtree which is obtained from 1022 NetBSD. The output is generally the same, but may vary 1023 slightly. If you found you need identical output adding 1024 "-F freebsd9" to the command line should do the trick. For the 1025 time being, the old mtree is available as fmtree. 1026 102720131014: 1028 libbsdyml has been renamed to libyaml and moved to /usr/lib/private. 1029 This will break ports-mgmt/pkg. Rebuild the port, or upgrade to pkg 1030 1.1.4_8 and verify bsdyml not linked in, before running "make 1031 delete-old-libs": 1032 # make -C /usr/ports/ports-mgmt/pkg build deinstall install clean 1033 or 1034 # pkg install pkg; ldd /usr/local/sbin/pkg | grep bsdyml 1035 103620131010: 1037 The stable/10 branch has been created in subversion from head 1038 revision r256279. 1039 104020131010: 1041 The rc.d/jail script has been updated to support jail(8) 1042 configuration file. The "jail_<jname>_*" rc.conf(5) variables 1043 for per-jail configuration are automatically converted to 1044 /var/run/jail.<jname>.conf before the jail(8) utility is invoked. 1045 This is transparently backward compatible. See below about some 1046 incompatibilities and rc.conf(5) manual page for more details. 1047 1048 These variables are now deprecated in favor of jail(8) configuration 1049 file. One can use "rc.d/jail config <jname>" command to generate 1050 a jail(8) configuration file in /var/run/jail.<jname>.conf without 1051 running the jail(8) utility. The default pathname of the 1052 configuration file is /etc/jail.conf and can be specified by 1053 using $jail_conf or $jail_<jname>_conf variables. 1054 1055 Please note that jail_devfs_ruleset accepts an integer at 1056 this moment. Please consider to rewrite the ruleset name 1057 with an integer. 1058 105920130930: 1060 BIND has been removed from the base system. If all you need 1061 is a local resolver, simply enable and start the local_unbound 1062 service instead. Otherwise, several versions of BIND are 1063 available in the ports tree. The dns/bind99 port is one example. 1064 1065 With this change, nslookup(1) and dig(1) are no longer in the base 1066 system. Users should instead use host(1) and drill(1) which are 1067 in the base system. Alternatively, nslookup and dig can 1068 be obtained by installing the dns/bind-tools port. 1069 107020130916: 1071 With the addition of unbound(8), a new unbound user is now 1072 required during installworld. "mergemaster -p" can be used to 1073 add the user prior to installworld, as documented in the handbook. 1074 107520130911: 1076 OpenSSH is now built with DNSSEC support, and will by default 1077 silently trust signed SSHFP records. This can be controlled with 1078 the VerifyHostKeyDNS client configuration setting. DNSSEC support 1079 can be disabled entirely with the WITHOUT_LDNS option in src.conf. 1080 108120130906: 1082 The GNU Compiler Collection and C++ standard library (libstdc++) 1083 are no longer built by default on platforms where clang is the system 1084 compiler. You can enable them with the WITH_GCC and WITH_GNUCXX 1085 options in src.conf. 1086 108720130905: 1088 The PROCDESC kernel option is now part of the GENERIC kernel 1089 configuration and is required for the rwhod(8) to work. 1090 If you are using custom kernel configuration, you should include 1091 'options PROCDESC'. 1092 109320130905: 1094 The API and ABI related to the Capsicum framework was modified 1095 in backward incompatible way. The userland libraries and programs 1096 have to be recompiled to work with the new kernel. This includes the 1097 following libraries and programs, but the whole buildworld is 1098 advised: libc, libprocstat, dhclient, tcpdump, hastd, hastctl, 1099 kdump, procstat, rwho, rwhod, uniq. 1100 110120130903: 1102 AES-NI intrinsic support has been added to gcc. The AES-NI module 1103 has been updated to use this support. A new gcc is required to build 1104 the aesni module on both i386 and amd64. 1105 110620130821: 1107 The PADLOCK_RNG and RDRAND_RNG kernel options are now devices. 1108 Thus "device padlock_rng" and "device rdrand_rng" should be 1109 used instead of "options PADLOCK_RNG" & "options RDRAND_RNG". 1110 111120130813: 1112 WITH_ICONV has been split into two feature sets. WITH_ICONV now 1113 enables just the iconv* functionality and is now on by default. 1114 WITH_LIBICONV_COMPAT enables the libiconv api and link time 1115 compatibility. Set WITHOUT_ICONV to build the old way. 1116 If you have been using WITH_ICONV before, you will very likely 1117 need to turn on WITH_LIBICONV_COMPAT. 1118 111920130806: 1120 INVARIANTS option now enables DEBUG for code with OpenSolaris and 1121 Illumos origin, including ZFS. If you have INVARIANTS in your 1122 kernel configuration, then there is no need to set DEBUG or ZFS_DEBUG 1123 explicitly. 1124 DEBUG used to enable witness(9) tracking of OpenSolaris (mostly ZFS) 1125 locks if WITNESS option was set. Because that generated a lot of 1126 witness(9) reports and all of them were believed to be false 1127 positives, this is no longer done. New option OPENSOLARIS_WITNESS 1128 can be used to achieve the previous behavior. 1129 113020130806: 1131 Timer values in IPv6 data structures now use time_uptime instead 1132 of time_second. Although this is not a user-visible functional 1133 change, userland utilities which directly use them---ndp(8), 1134 rtadvd(8), and rtsold(8) in the base system---need to be updated 1135 to r253970 or later. 1136 113720130802: 1138 find -delete can now delete the pathnames given as arguments, 1139 instead of only files found below them or if the pathname did 1140 not contain any slashes. Formerly, the following error message 1141 would result: 1142 1143 find: -delete: <path>: relative path potentially not safe 1144 1145 Deleting the pathnames given as arguments can be prevented 1146 without error messages using -mindepth 1 or by changing 1147 directory and passing "." as argument to find. This works in the 1148 old as well as the new version of find. 1149 115020130726: 1151 Behavior of devfs rules path matching has been changed. 1152 Pattern is now always matched against fully qualified devfs 1153 path and slash characters must be explicitly matched by 1154 slashes in pattern (FNM_PATHNAME). Rulesets involving devfs 1155 subdirectories must be reviewed. 1156 115720130716: 1158 The default ARM ABI has changed to the ARM EABI. The old ABI is 1159 incompatible with the ARM EABI and all programs and modules will 1160 need to be rebuilt to work with a new kernel. 1161 1162 To keep using the old ABI ensure the WITHOUT_ARM_EABI knob is set. 1163 1164 NOTE: Support for the old ABI will be removed in the future and 1165 users are advised to upgrade. 1166 116720130709: 1168 pkg_install has been disconnected from the build if you really need it 1169 you should add WITH_PKGTOOLS in your src.conf(5). 1170 117120130709: 1172 Most of network statistics structures were changed to be able 1173 keep 64-bits counters. Thus all tools, that work with networking 1174 statistics, must be rebuilt (netstat(1), bsnmpd(1), etc.) 1175 117620130618: 1177 Fix a bug that allowed a tracing process (e.g. gdb) to write 1178 to a memory-mapped file in the traced process's address space 1179 even if neither the traced process nor the tracing process had 1180 write access to that file. 1181 118220130615: 1183 CVS has been removed from the base system. An exact copy 1184 of the code is available from the devel/cvs port. 1185 118620130613: 1187 Some people report the following error after the switch to bmake: 1188 1189 make: illegal option -- J 1190 usage: make [-BPSXeiknpqrstv] [-C directory] [-D variable] 1191 ... 1192 *** [buildworld] Error code 2 1193 1194 this likely due to an old instance of make in 1195 ${MAKEPATH} (${MAKEOBJDIRPREFIX}${.CURDIR}/make.${MACHINE}) 1196 which src/Makefile will use that blindly, if it exists, so if 1197 you see the above error: 1198 1199 rm -rf `make -V MAKEPATH` 1200 1201 should resolve it. 1202 120320130516: 1204 Use bmake by default. 1205 Whereas before one could choose to build with bmake via 1206 -DWITH_BMAKE one must now use -DWITHOUT_BMAKE to use the old 1207 make. The goal is to remove these knobs for 10-RELEASE. 1208 1209 It is worth noting that bmake (like gmake) treats the command 1210 line as the unit of failure, rather than statements within the 1211 command line. Thus '(cd some/where && dosomething)' is safer 1212 than 'cd some/where; dosomething'. The '()' allows consistent 1213 behavior in parallel build. 1214 121520130429: 1216 Fix a bug that allows NFS clients to issue READDIR on files. 1217 121820130426: 1219 The WITHOUT_IDEA option has been removed because 1220 the IDEA patent expired. 1221 122220130426: 1223 The sysctl which controls TRIM support under ZFS has been renamed 1224 from vfs.zfs.trim_disable -> vfs.zfs.trim.enabled and has been 1225 enabled by default. 1226 122720130425: 1228 The mergemaster command now uses the default MAKEOBJDIRPREFIX 1229 rather than creating it's own in the temporary directory in 1230 order allow access to bootstrapped versions of tools such as 1231 install and mtree. When upgrading from version of FreeBSD where 1232 the install command does not support -l, you will need to 1233 install a new mergemaster command if mergemaster -p is required. 1234 This can be accomplished with the command (cd src/usr.sbin/mergemaster 1235 && make install). 1236 123720130404: 1238 Legacy ATA stack, disabled and replaced by new CAM-based one since 1239 FreeBSD 9.0, completely removed from the sources. Kernel modules 1240 atadisk and atapi*, user-level tools atacontrol and burncd are 1241 removed. Kernel option `options ATA_CAM` is now permanently enabled 1242 and removed. 1243 124420130319: 1245 SOCK_CLOEXEC and SOCK_NONBLOCK flags have been added to socket(2) 1246 and socketpair(2). Software, in particular Kerberos, may 1247 automatically detect and use these during building. The resulting 1248 binaries will not work on older kernels. 1249 125020130308: 1251 CTL_DISABLE has also been added to the sparc64 GENERIC (for further 1252 information, see the respective 20130304 entry). 1253 125420130304: 1255 Recent commits to callout(9) changed the size of struct callout, 1256 so the KBI is probably heavily disturbed. Also, some functions 1257 in callout(9)/sleep(9)/sleepqueue(9)/condvar(9) KPIs were replaced 1258 by macros. Every kernel module using it won't load, so rebuild 1259 is requested. 1260 1261 The ctl device has been re-enabled in GENERIC for i386 and amd64, 1262 but does not initialize by default (because of the new CTL_DISABLE 1263 option) to save memory. To re-enable it, remove the CTL_DISABLE 1264 option from the kernel config file or set kern.cam.ctl.disable=0 1265 in /boot/loader.conf. 1266 126720130301: 1268 The ctl device has been disabled in GENERIC for i386 and amd64. 1269 This was done due to the extra memory being allocated at system 1270 initialisation time by the ctl driver which was only used if 1271 a CAM target device was created. This makes a FreeBSD system 1272 unusable on 128MB or less of RAM. 1273 127420130208: 1275 A new compression method (lz4) has been merged to -HEAD. Please 1276 refer to zpool-features(7) for more information. 1277 1278 Please refer to the "ZFS notes" section of this file for information 1279 on upgrading boot ZFS pools. 1280 128120130129: 1282 A BSD-licensed patch(1) variant has been added and is installed 1283 as bsdpatch, being the GNU version the default patch. 1284 To inverse the logic and use the BSD-licensed one as default, 1285 while having the GNU version installed as gnupatch, rebuild 1286 and install world with the WITH_BSD_PATCH knob set. 1287 128820130121: 1289 Due to the use of the new -l option to install(1) during build 1290 and install, you must take care not to directly set the INSTALL 1291 make variable in your /etc/make.conf, /etc/src.conf, or on the 1292 command line. If you wish to use the -C flag for all installs 1293 you may be able to add INSTALL+=-C to /etc/make.conf or 1294 /etc/src.conf. 1295 129620130118: 1297 The install(1) option -M has changed meaning and now takes an 1298 argument that is a file or path to append logs to. In the 1299 unlikely event that -M was the last option on the command line 1300 and the command line contained at least two files and a target 1301 directory the first file will have logs appended to it. The -M 1302 option served little practical purpose in the last decade so its 1303 use is expected to be extremely rare. 1304 130520121223: 1306 After switching to Clang as the default compiler some users of ZFS 1307 on i386 systems started to experience stack overflow kernel panics. 1308 Please consider using 'options KSTACK_PAGES=4' in such configurations. 1309 131020121222: 1311 GEOM_LABEL now mangles label names read from file system metadata. 1312 Mangling affect labels containing spaces, non-printable characters, 1313 '%' or '"'. Device names in /etc/fstab and other places may need to 1314 be updated. 1315 131620121217: 1317 By default, only the 10 most recent kernel dumps will be saved. To 1318 restore the previous behaviour (no limit on the number of kernel dumps 1319 stored in the dump directory) add the following line to /etc/rc.conf: 1320 1321 savecore_flags="" 1322 132320121201: 1324 With the addition of auditdistd(8), a new auditdistd user is now 1325 required during installworld. "mergemaster -p" can be used to 1326 add the user prior to installworld, as documented in the handbook. 1327 132820121117: 1329 The sin6_scope_id member variable in struct sockaddr_in6 is now 1330 filled by the kernel before passing the structure to the userland via 1331 sysctl or routing socket. This means the KAME-specific embedded scope 1332 id in sin6_addr.s6_addr[2] is always cleared in userland application. 1333 This behavior can be controlled by net.inet6.ip6.deembed_scopeid. 1334 __FreeBSD_version is bumped to 1000025. 1335 133620121105: 1337 On i386 and amd64 systems WITH_CLANG_IS_CC is now the default. 1338 This means that the world and kernel will be compiled with clang 1339 and that clang will be installed as /usr/bin/cc, /usr/bin/c++, 1340 and /usr/bin/cpp. To disable this behavior and revert to building 1341 with gcc, compile with WITHOUT_CLANG_IS_CC. Really old versions 1342 of current may need to bootstrap WITHOUT_CLANG first if the clang 1343 build fails (its compatibility window doesn't extend to the 9 stable 1344 branch point). 1345 134620121102: 1347 The IPFIREWALL_FORWARD kernel option has been removed. Its 1348 functionality now turned on by default. 1349 135020121023: 1351 The ZERO_COPY_SOCKET kernel option has been removed and 1352 split into SOCKET_SEND_COW and SOCKET_RECV_PFLIP. 1353 NB: SOCKET_SEND_COW uses the VM page based copy-on-write 1354 mechanism which is not safe and may result in kernel crashes. 1355 NB: The SOCKET_RECV_PFLIP mechanism is useless as no current 1356 driver supports disposeable external page sized mbuf storage. 1357 Proper replacements for both zero-copy mechanisms are under 1358 consideration and will eventually lead to complete removal 1359 of the two kernel options. 1360 136120121023: 1362 The IPv4 network stack has been converted to network byte 1363 order. The following modules need to be recompiled together 1364 with kernel: carp(4), divert(4), gif(4), siftr(4), gre(4), 1365 pf(4), ipfw(4), ng_ipfw(4), stf(4). 1366 136720121022: 1368 Support for non-MPSAFE filesystems was removed from VFS. The 1369 VFS_VERSION was bumped, all filesystem modules shall be 1370 recompiled. 1371 137220121018: 1373 All the non-MPSAFE filesystems have been disconnected from 1374 the build. The full list includes: codafs, hpfs, ntfs, nwfs, 1375 portalfs, smbfs, xfs. 1376 137720121016: 1378 The interface cloning API and ABI has changed. The following 1379 modules need to be recompiled together with kernel: 1380 ipfw(4), pfsync(4), pflog(4), usb(4), wlan(4), stf(4), 1381 vlan(4), disc(4), edsc(4), if_bridge(4), gif(4), tap(4), 1382 faith(4), epair(4), enc(4), tun(4), if_lagg(4), gre(4). 1383 138420121015: 1385 The sdhci driver was split in two parts: sdhci (generic SD Host 1386 Controller logic) and sdhci_pci (actual hardware driver). 1387 No kernel config modifications are required, but if you 1388 load sdhc as a module you must switch to sdhci_pci instead. 1389 139020121014: 1391 Import the FUSE kernel and userland support into base system. 1392 139320121013: 1394 The GNU sort(1) program has been removed since the BSD-licensed 1395 sort(1) has been the default for quite some time and no serious 1396 problems have been reported. The corresponding WITH_GNU_SORT 1397 knob has also gone. 1398 139920121006: 1400 The pfil(9) API/ABI for AF_INET family has been changed. Packet 1401 filtering modules: pf(4), ipfw(4), ipfilter(4) need to be recompiled 1402 with new kernel. 1403 140420121001: 1405 The net80211(4) ABI has been changed to allow for improved driver 1406 PS-POLL and power-save support. All wireless drivers need to be 1407 recompiled to work with the new kernel. 1408 140920120913: 1410 The random(4) support for the VIA hardware random number 1411 generator (`PADLOCK') is no longer enabled unconditionally. 1412 Add the padlock_rng device in the custom kernel config if 1413 needed. The GENERIC kernels on i386 and amd64 do include the 1414 device, so the change only affects the custom kernel 1415 configurations. 1416 141720120908: 1418 The pf(4) packet filter ABI has been changed. pfctl(8) and 1419 snmp_pf module need to be recompiled to work with new kernel. 1420 142120120828: 1422 A new ZFS feature flag "com.delphix:empty_bpobj" has been merged 1423 to -HEAD. Pools that have empty_bpobj in active state can not be 1424 imported read-write with ZFS implementations that do not support 1425 this feature. For more information read the zpool-features(5) 1426 manual page. 1427 142820120727: 1429 The sparc64 ZFS loader has been changed to no longer try to auto- 1430 detect ZFS providers based on diskN aliases but now requires these 1431 to be explicitly listed in the OFW boot-device environment variable. 1432 143320120712: 1434 The OpenSSL has been upgraded to 1.0.1c. Any binaries requiring 1435 libcrypto.so.6 or libssl.so.6 must be recompiled. Also, there are 1436 configuration changes. Make sure to merge /etc/ssl/openssl.cnf. 1437 143820120712: 1439 The following sysctls and tunables have been renamed for consistency 1440 with other variables: 1441 kern.cam.da.da_send_ordered -> kern.cam.da.send_ordered 1442 kern.cam.ada.ada_send_ordered -> kern.cam.ada.send_ordered 1443 144420120628: 1445 The sort utility has been replaced with BSD sort. For now, GNU sort 1446 is also available as "gnusort" or the default can be set back to 1447 GNU sort by setting WITH_GNU_SORT. In this case, BSD sort will be 1448 installed as "bsdsort". 1449 145020120611: 1451 A new version of ZFS (pool version 5000) has been merged to -HEAD. 1452 Starting with this version the old system of ZFS pool versioning 1453 is superseded by "feature flags". This concept enables forward 1454 compatibility against certain future changes in functionality of ZFS 1455 pools. The first read-only compatible "feature flag" for ZFS pools 1456 is named "com.delphix:async_destroy". For more information 1457 read the new zpool-features(5) manual page. 1458 Please refer to the "ZFS notes" section of this file for information 1459 on upgrading boot ZFS pools. 1460 146120120417: 1462 The malloc(3) implementation embedded in libc now uses sources imported 1463 as contrib/jemalloc. The most disruptive API change is to 1464 /etc/malloc.conf. If your system has an old-style /etc/malloc.conf, 1465 delete it prior to installworld, and optionally re-create it using the 1466 new format after rebooting. See malloc.conf(5) for details 1467 (specifically the TUNING section and the "opt.*" entries in the MALLCTL 1468 NAMESPACE section). 1469 147020120328: 1471 Big-endian MIPS TARGET_ARCH values no longer end in "eb". mips64eb 1472 is now spelled mips64. mipsn32eb is now spelled mipsn32. mipseb is 1473 now spelled mips. This is to aid compatibility with third-party 1474 software that expects this naming scheme in uname(3). Little-endian 1475 settings are unchanged. If you are updating a big-endian mips64 machine 1476 from before this change, you may need to set MACHINE_ARCH=mips64 in 1477 your environment before the new build system will recognize your machine. 1478 147920120306: 1480 Disable by default the option VFS_ALLOW_NONMPSAFE for all supported 1481 platforms. 1482 148320120229: 1484 Now unix domain sockets behave "as expected" on nullfs(5). Previously 1485 nullfs(5) did not pass through all behaviours to the underlying layer, 1486 as a result if we bound to a socket on the lower layer we could connect 1487 only to the lower path; if we bound to the upper layer we could connect 1488 only to the upper path. The new behavior is one can connect to both the 1489 lower and the upper paths regardless what layer path one binds to. 1490 149120120211: 1492 The getifaddrs upgrade path broken with 20111215 has been restored. 1493 If you have upgraded in between 20111215 and 20120209 you need to 1494 recompile libc again with your kernel. You still need to recompile 1495 world to be able to configure CARP but this restriction already 1496 comes from 20111215. 1497 149820120114: 1499 The set_rcvar() function has been removed from /etc/rc.subr. All 1500 base and ports rc.d scripts have been updated, so if you have a 1501 port installed with a script in /usr/local/etc/rc.d you can either 1502 hand-edit the rcvar= line, or reinstall the port. 1503 1504 An easy way to handle the mass-update of /etc/rc.d: 1505 rm /etc/rc.d/* && mergemaster -i 1506 150720120109: 1508 panic(9) now stops other CPUs in the SMP systems, disables interrupts 1509 on the current CPU and prevents other threads from running. 1510 This behavior can be reverted using the kern.stop_scheduler_on_panic 1511 tunable/sysctl. 1512 The new behavior can be incompatible with kern.sync_on_panic. 1513 151420111215: 1515 The carp(4) facility has been changed significantly. Configuration 1516 of the CARP protocol via ifconfig(8) has changed, as well as format 1517 of CARP events submitted to devd(8) has changed. See manual pages 1518 for more information. The arpbalance feature of carp(4) is currently 1519 not supported anymore. 1520 1521 Size of struct in_aliasreq, struct in6_aliasreq has changed. User 1522 utilities using SIOCAIFADDR, SIOCAIFADDR_IN6, e.g. ifconfig(8), 1523 need to be recompiled. 1524 152520111122: 1526 The acpi_wmi(4) status device /dev/wmistat has been renamed to 1527 /dev/wmistat0. 1528 152920111108: 1530 The option VFS_ALLOW_NONMPSAFE option has been added in order to 1531 explicitely support non-MPSAFE filesystems. 1532 It is on by default for all supported platform at this present 1533 time. 1534 153520111101: 1536 The broken amd(4) driver has been replaced with esp(4) in the amd64, 1537 i386 and pc98 GENERIC kernel configuration files. 1538 153920110930: 1540 sysinstall has been removed 1541 154220110923: 1543 The stable/9 branch created in subversion. This corresponds to the 1544 RELENG_9 branch in CVS. 1545 1546COMMON ITEMS: 1547 1548 General Notes 1549 ------------- 1550 Avoid using make -j when upgrading. While generally safe, there are 1551 sometimes problems using -j to upgrade. If your upgrade fails with 1552 -j, please try again without -j. From time to time in the past there 1553 have been problems using -j with buildworld and/or installworld. This 1554 is especially true when upgrading between "distant" versions (eg one 1555 that cross a major release boundary or several minor releases, or when 1556 several months have passed on the -current branch). 1557 1558 Sometimes, obscure build problems are the result of environment 1559 poisoning. This can happen because the make utility reads its 1560 environment when searching for values for global variables. To run 1561 your build attempts in an "environmental clean room", prefix all make 1562 commands with 'env -i '. See the env(1) manual page for more details. 1563 1564 When upgrading from one major version to another it is generally best 1565 to upgrade to the latest code in the currently installed branch first, 1566 then do an upgrade to the new branch. This is the best-tested upgrade 1567 path, and has the highest probability of being successful. Please try 1568 this approach before reporting problems with a major version upgrade. 1569 1570 When upgrading a live system, having a root shell around before 1571 installing anything can help undo problems. Not having a root shell 1572 around can lead to problems if pam has changed too much from your 1573 starting point to allow continued authentication after the upgrade. 1574 1575 This file should be read as a log of events. When a later event changes 1576 information of a prior event, the prior event should not be deleted. 1577 Instead, a pointer to the entry with the new information should be 1578 placed in the old entry. Readers of this file should also sanity check 1579 older entries before relying on them blindly. Authors of new entries 1580 should write them with this in mind. 1581 1582 ZFS notes 1583 --------- 1584 When upgrading the boot ZFS pool to a new version, always follow 1585 these two steps: 1586 1587 1.) recompile and reinstall the ZFS boot loader and boot block 1588 (this is part of "make buildworld" and "make installworld") 1589 1590 2.) update the ZFS boot block on your boot drive 1591 1592 The following example updates the ZFS boot block on the first 1593 partition (freebsd-boot) of a GPT partitioned drive ada0: 1594 "gpart bootcode -p /boot/gptzfsboot -i 1 ada0" 1595 1596 Non-boot pools do not need these updates. 1597 1598 To build a kernel 1599 ----------------- 1600 If you are updating from a prior version of FreeBSD (even one just 1601 a few days old), you should follow this procedure. It is the most 1602 failsafe as it uses a /usr/obj tree with a fresh mini-buildworld, 1603 1604 make kernel-toolchain 1605 make -DALWAYS_CHECK_MAKE buildkernel KERNCONF=YOUR_KERNEL_HERE 1606 make -DALWAYS_CHECK_MAKE installkernel KERNCONF=YOUR_KERNEL_HERE 1607 1608 To test a kernel once 1609 --------------------- 1610 If you just want to boot a kernel once (because you are not sure 1611 if it works, or if you want to boot a known bad kernel to provide 1612 debugging information) run 1613 make installkernel KERNCONF=YOUR_KERNEL_HERE KODIR=/boot/testkernel 1614 nextboot -k testkernel 1615 1616 To just build a kernel when you know that it won't mess you up 1617 -------------------------------------------------------------- 1618 This assumes you are already running a CURRENT system. Replace 1619 ${arch} with the architecture of your machine (e.g. "i386", 1620 "arm", "amd64", "ia64", "pc98", "sparc64", "powerpc", "mips", etc). 1621 1622 cd src/sys/${arch}/conf 1623 config KERNEL_NAME_HERE 1624 cd ../compile/KERNEL_NAME_HERE 1625 make depend 1626 make 1627 make install 1628 1629 If this fails, go to the "To build a kernel" section. 1630 1631 To rebuild everything and install it on the current system. 1632 ----------------------------------------------------------- 1633 # Note: sometimes if you are running current you gotta do more than 1634 # is listed here if you are upgrading from a really old current. 1635 1636 <make sure you have good level 0 dumps> 1637 make buildworld 1638 make kernel KERNCONF=YOUR_KERNEL_HERE 1639 [1] 1640 <reboot in single user> [3] 1641 mergemaster -Fp [5] 1642 make installworld 1643 mergemaster -Fi [4] 1644 make delete-old [6] 1645 <reboot> 1646 1647 To cross-install current onto a separate partition 1648 -------------------------------------------------- 1649 # In this approach we use a separate partition to hold 1650 # current's root, 'usr', and 'var' directories. A partition 1651 # holding "/", "/usr" and "/var" should be about 2GB in 1652 # size. 1653 1654 <make sure you have good level 0 dumps> 1655 <boot into -stable> 1656 make buildworld 1657 make buildkernel KERNCONF=YOUR_KERNEL_HERE 1658 <maybe newfs current's root partition> 1659 <mount current's root partition on directory ${CURRENT_ROOT}> 1660 make installworld DESTDIR=${CURRENT_ROOT} -DDB_FROM_SRC 1661 make distribution DESTDIR=${CURRENT_ROOT} # if newfs'd 1662 make installkernel KERNCONF=YOUR_KERNEL_HERE DESTDIR=${CURRENT_ROOT} 1663 cp /etc/fstab ${CURRENT_ROOT}/etc/fstab # if newfs'd 1664 <edit ${CURRENT_ROOT}/etc/fstab to mount "/" from the correct partition> 1665 <reboot into current> 1666 <do a "native" rebuild/install as described in the previous section> 1667 <maybe install compatibility libraries from ports/misc/compat*> 1668 <reboot> 1669 1670 1671 To upgrade in-place from stable to current 1672 ---------------------------------------------- 1673 <make sure you have good level 0 dumps> 1674 make buildworld [9] 1675 make kernel KERNCONF=YOUR_KERNEL_HERE [8] 1676 [1] 1677 <reboot in single user> [3] 1678 mergemaster -Fp [5] 1679 make installworld 1680 mergemaster -Fi [4] 1681 make delete-old [6] 1682 <reboot> 1683 1684 Make sure that you've read the UPDATING file to understand the 1685 tweaks to various things you need. At this point in the life 1686 cycle of current, things change often and you are on your own 1687 to cope. The defaults can also change, so please read ALL of 1688 the UPDATING entries. 1689 1690 Also, if you are tracking -current, you must be subscribed to 1691 freebsd-current@freebsd.org. Make sure that before you update 1692 your sources that you have read and understood all the recent 1693 messages there. If in doubt, please track -stable which has 1694 much fewer pitfalls. 1695 1696 [1] If you have third party modules, such as vmware, you 1697 should disable them at this point so they don't crash your 1698 system on reboot. 1699 1700 [3] From the bootblocks, boot -s, and then do 1701 fsck -p 1702 mount -u / 1703 mount -a 1704 cd src 1705 adjkerntz -i # if CMOS is wall time 1706 Also, when doing a major release upgrade, it is required that 1707 you boot into single user mode to do the installworld. 1708 1709 [4] Note: This step is non-optional. Failure to do this step 1710 can result in a significant reduction in the functionality of the 1711 system. Attempting to do it by hand is not recommended and those 1712 that pursue this avenue should read this file carefully, as well 1713 as the archives of freebsd-current and freebsd-hackers mailing lists 1714 for potential gotchas. The -U option is also useful to consider. 1715 See mergemaster(8) for more information. 1716 1717 [5] Usually this step is a noop. However, from time to time 1718 you may need to do this if you get unknown user in the following 1719 step. It never hurts to do it all the time. You may need to 1720 install a new mergemaster (cd src/usr.sbin/mergemaster && make 1721 install) after the buildworld before this step if you last updated 1722 from current before 20130425 or from -stable before 20130430. 1723 1724 [6] This only deletes old files and directories. Old libraries 1725 can be deleted by "make delete-old-libs", but you have to make 1726 sure that no program is using those libraries anymore. 1727 1728 [8] In order to have a kernel that can run the 4.x binaries needed to 1729 do an installworld, you must include the COMPAT_FREEBSD4 option in 1730 your kernel. Failure to do so may leave you with a system that is 1731 hard to boot to recover. A similar kernel option COMPAT_FREEBSD5 is 1732 required to run the 5.x binaries on more recent kernels. And so on 1733 for COMPAT_FREEBSD6 and COMPAT_FREEBSD7. 1734 1735 Make sure that you merge any new devices from GENERIC since the 1736 last time you updated your kernel config file. 1737 1738 [9] When checking out sources, you must include the -P flag to have 1739 cvs prune empty directories. 1740 1741 If CPUTYPE is defined in your /etc/make.conf, make sure to use the 1742 "?=" instead of the "=" assignment operator, so that buildworld can 1743 override the CPUTYPE if it needs to. 1744 1745 MAKEOBJDIRPREFIX must be defined in an environment variable, and 1746 not on the command line, or in /etc/make.conf. buildworld will 1747 warn if it is improperly defined. 1748FORMAT: 1749 1750This file contains a list, in reverse chronological order, of major 1751breakages in tracking -current. It is not guaranteed to be a complete 1752list of such breakages, and only contains entries since September 23, 2011. 1753If you need to see UPDATING entries from before that date, you will need 1754to fetch an UPDATING file from an older FreeBSD release. 1755 1756Copyright information: 1757 1758Copyright 1998-2009 M.
