UPDATING revision 338017
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 1920180818: 20 WITH_OFED option now only enables the build for the OFED libraries 21 and some fundamental client utilities. OpenSM and rest of the 22 debugging tools are enabled by WITH_OFED_EXTRA build switch. 23 WITH_OFED is turned on by default on amd64. 24 2520180714: 26 Clang, llvm, lld, lldb, compiler-rt and libc++ have been upgraded to 27 6.0.1. Please see the 20141231 entry below for information about 28 prerequisites and upgrading, if you are not already using clang 3.5.0 29 or higher. 30 3120180601: 32 The releng/11.2 branch has been created from stable/11@r334458. 33 3420180504: 35 The tz database (tzdb) has been updated to 2018e. This version more 36 correctly models time stamps in time zones with negative DST such as 37 Europe/Dublin (from 1971 on), Europe/Prague (1946/7), and 38 Africa/Windhoek (1994/2017). This does not affect the UT offsets, only 39 time zone abbreviations and the tm_isdst flag. 40 4120180409: 42 The use of RSS hash from the network card aka flowid has been 43 disabled by default for lagg(4) as it's currently incompatible with 44 the lacp and loadbalance protocols. 45 46 This can be re-enabled by setting the following in loader.conf: 47 net.link.lagg.default_use_flowid="1" 48 4920180331: 50 Clang, llvm, lld, lldb, compiler-rt and libc++ have been upgraded to 51 6.0.0. Please see the 20141231 entry below for information about 52 prerequisites and upgrading, if you are not already using clang 3.5.0 53 or higher. 54 5520180211: 56 The LOADER_FIREWIRE_SUPPORT build variable as been renamed to 57 WITH/OUT_LOADER_FIREWIRE. LOADER_{NO_,}GELI_SUPPORT has been renamed 58 to WITH/OUT_LOADER_GELI. 59 6020180210: 61 The geli password typed at boot is now hidden. To restore the previous 62 behavior, see geli(8) for configuration options. 63 64 The SW_WATCHDOG option is no longer necessary to enable the 65 hardclock-based software watchdog if no hardware watchdog is 66 configured. As before, SW_WATCHDOG will cause the software 67 watchdog to be enabled even if a hardware watchdog is configured. 68 6920180108: 70 lint(1) binaries and library are no longer built by default. To 71 enable building them, define WITH_LINT in src.conf. If you are using 72 a FreeBSD 12 or later system to build 11-stable, you may need to 73 install a lint(1) binary to use WITH_LINT. 74 7520171003: 76 When building multiple kernels using KERNCONF, non-existent KERNCONF 77 files will produce an error and buildkernel will fail. Previously 78 missing KERNCONF files silently failed giving no indication as to 79 why, only to subsequently discover during installkernel that the 80 desired kernel was never built in the first place. 81 8220170926: 83 Clang, llvm, lldb, compiler-rt and libc++ have been upgraded to 5.0.0. 84 Please see the 20141231 entry below for information about prerequisites 85 and upgrading, if you are not already using clang 3.5.0 or higher. 86 8720170822: 88 Since the switch to GPT disk labels, fsck for UFS/FFS has been 89 unable to automatically find alternate superblocks. As of r322806, 90 the information needed to find alternate superblocks has been 91 moved to the end of the area reserved for the boot block. 92 Filesystems created with a newfs of this vintage or later 93 will create the recovery information. If you have a filesystem 94 created prior to this change and wish to have a recovery block 95 created for your filesystem, you can do so by running fsck in 96 forground mode (i.e., do not use the -p or -y options). As it 97 starts, fsck will ask ``SAVE DATA TO FIND ALTERNATE SUPERBLOCKS'' 98 to which you should answer yes. 99 10020170629: 101 The releng/11.1 branch has been created from stable/11@r320475. 102 10320170518: 104 arm64 builds now use the base system LLD 4.0.0 linker by default, 105 instead of requiring that the aarch64-binutils port or package be 106 installed. To continue using aarch64-binutils, set 107 CROSS_BINUTILS_PREFIX=/usr/local/aarch64-freebsd/bin . 108 10920170529: 110 The ctl.ko module no longer implements the iSCSI target frontend: 111 cfiscsi.ko does instead. 112 113 If building cfiscsi.ko as a kernel module, the module can be loaded 114 via one of the following methods: 115 - `cfiscsi_load="YES"` in loader.conf(5). 116 - Add `cfiscsi` to `$kld_list` in rc.conf(5). 117 - ctladm(8)/ctld(8), when compiled with iSCSI support 118 (`WITH_ISCSI=yes` in src.conf(5)) 119 120 Please see cfiscsi(4) for more details. 121 12220170511: 123 The mmcsd.ko module now additionally depends on geom_flashmap.ko. 124 Also, mmc.ko and mmcsd.ko need to be a matching pair built from the 125 same source (previously, the dependency of mmcsd.ko on mmc.ko was 126 missing, but mmcsd.ko now will refuse to load if it is incompatible 127 with mmc.ko). 128 12920170414: 130 Binds and sends to the loopback addresses, IPv6 and IPv4, will now 131 use any explicitly assigned loopback address available in the jail 132 instead of using the first assigned address of the jail. 133 13420170413: 135 As of r316810 for ipfilter, keep frags is no longer assumed when 136 keep state is specified in a rule. r316810 aligns ipfilter with 137 documentation in man pages separating keep frags from keep state. 138 This allows keep state to specified without forcing keep frags 139 and allows keep frags to be specified independently of keep state. 140 To maintain previous behaviour, also specify keep frags with 141 keep state (as documented in ipf.conf.5). 142 14320170402: 144 Clang, llvm, lldb, compiler-rt and libc++ have been upgraded to 4.0.0. 145 Please see the 20141231 entry below for information about prerequisites 146 and upgrading, if you are not already using clang 3.5.0 or higher. 147 14820170323: 149 The code that provides support for ZFS .zfs/ directory functionality 150 has been reimplemented. It's not possible now to create a snapshot 151 by mkdir under .zfs/snapshot/. That should be the only user visible 152 change. 153 15420170319: 155 Many changes in the IPsec code have been merged from the FreeBSD-CURRENT 156 branch. The IPSEC_FILTERTUNNEL kernel option is removed in favour of 157 corresponding sysctl. The IPSEC_NAT_T kernel option is also removed, 158 and now NAT-T is supported by default. Security associations now use 159 the single namespace for SPI allocation, so if you use several manually 160 configured security associations with the same SPI, this configuration 161 needs modification. 162 16320161217: 164 Clang, llvm, lldb, compiler-rt and libc++ have been upgraded to 3.9.1. 165 Please see the 20141231 entry below for information about prerequisites 166 and upgrading, if you are not already using clang 3.5.0 or higher. 167 16820161124: 169 Clang, llvm, lldb, compiler-rt and libc++ have been upgraded to 3.9.0. 170 Please see the 20141231 entry below for information about prerequisites 171 and upgrading, if you are not already using clang 3.5.0 or higher. 172 17320161119: 174 The layout of the pmap structure has changed for powerpc to put the pmap 175 statistics at the front for all CPU variations. libkvm(3) and all tools 176 that link against it need to be recompiled. 177 17820161030: 179 isl(4) and cyapa(4) drivers now require a new driver, 180 chromebook_platform(4), to work properly on Chromebook-class hardware. 181 On other types of hardware the drivers may need to be configured using 182 device hints. Please see the corresponding manual pages for details. 183 18420161210: 185 Relocatable object files with the extension of .So have been renamed 186 to use an extension of .pico instead. The purpose of this change is 187 to avoid a name clash with shared libraries on case-insensitive file 188 systems. On those file systems, foo.So is the same file as foo.so. 189 19020160811: 191 The releng/11.0 branch has been created from stable/11@r303970. 192 19320160708: 194 The stable/11 branch has been created from head@r302406. 195 19620160622: 197 The libc stub for the pipe(2) system call has been replaced with 198 a wrapper that calls the pipe2(2) system call and the pipe(2) 199 system call is now only implemented by the kernels that include 200 "options COMPAT_FREEBSD10" in their config file (this is the 201 default). Users should ensure that this option is enabled in 202 their kernel or upgrade userspace to r302092 before upgrading their 203 kernel. 204 20520160527: 206 CAM will now strip leading spaces from SCSI disks' serial numbers. 207 This will effect users who create UFS filesystems on SCSI disks using 208 those disk's diskid device nodes. For example, if /etc/fstab 209 previously contained a line like 210 "/dev/diskid/DISK-%20%20%20%20%20%20%20ABCDEFG0123456", you should 211 change it to "/dev/diskid/DISK-ABCDEFG0123456". Users of geom 212 transforms like gmirror may also be affected. ZFS users should 213 generally be fine. 214 21520160523: 216 The bitstring(3) API has been updated with new functionality and 217 improved performance. But it is binary-incompatible with the old API. 218 Objects built with the new headers may not be linked against objects 219 built with the old headers. 220 22120160520: 222 The brk and sbrk functions have been removed from libc on arm64. 223 Binutils from ports has been updated to not link to these 224 functions and should be updated to the latest version before 225 installing a new libc. 226 22720160517: 228 The armv6 port now defaults to hard float ABI. Limited support 229 for running both hardfloat and soft float on the same system 230 is available using the libraries installed with -DWITH_LIBSOFT. 231 This has only been tested as an upgrade path for installworld 232 and packages may fail or need manual intervention to run. New 233 packages will be needed. 234 235 To update an existing self-hosted armv6hf system, you must add 236 TARGET_ARCH=armv6 on the make command line for both the build 237 and the install steps. 238 23920160510: 240 Kernel modules compiled outside of a kernel build now default to 241 installing to /boot/modules instead of /boot/kernel. Many kernel 242 modules built this way (such as those in ports) already overrode 243 KMODDIR explicitly to install into /boot/modules. However, 244 manually building and installing a module from /sys/modules will 245 now install to /boot/modules instead of /boot/kernel. 246 24720160414: 248 The CAM I/O scheduler has been committed to the kernel. There should be 249 no user visible impact. This does enable NCQ Trim on ada SSDs. While the 250 list of known rogues that claim support for this but actually corrupt 251 data is believed to be complete, be on the lookout for data 252 corruption. The known rogue list is believed to be complete: 253 254 o Crucial MX100, M550 drives with MU01 firmware. 255 o Micron M510 and M550 drives with MU01 firmware. 256 o Micron M500 prior to MU07 firmware 257 o Samsung 830, 840, and 850 all firmwares 258 o FCCT M500 all firmwares 259 260 Crucial has firmware http://www.crucial.com/usa/en/support-ssd-firmware 261 with working NCQ TRIM. For Micron branded drives, see your sales rep for 262 updated firmware. Black listed drives will work correctly because these 263 drives work correctly so long as no NCQ TRIMs are sent to them. Given 264 this list is the same as found in Linux, it's believed there are no 265 other rogues in the market place. All other models from the above 266 vendors work. 267 268 To be safe, if you are at all concerned, you can quirk each of your 269 drives to prevent NCQ from being sent by setting: 270 kern.cam.ada.X.quirks="0x2" 271 in loader.conf. If the drive requires the 4k sector quirk, set the 272 quirks entry to 0x3. 273 27420160330: 275 The FAST_DEPEND build option has been removed and its functionality is 276 now the one true way. The old mkdep(1) style of 'make depend' has 277 been removed. See 20160311 for further details. 278 27920160317: 280 Resource range types have grown from unsigned long to uintmax_t. All 281 drivers, and anything using libdevinfo, need to be recompiled. 282 28320160311: 284 WITH_FAST_DEPEND is now enabled by default for in-tree and out-of-tree 285 builds. It no longer runs mkdep(1) during 'make depend', and the 286 'make depend' stage can safely be skipped now as it is auto ran 287 when building 'make all' and will generate all SRCS and DPSRCS before 288 building anything else. Dependencies are gathered at compile time with 289 -MF flags kept in separate .depend files per object file. Users should 290 run 'make cleandepend' once if using -DNO_CLEAN to clean out older 291 stale .depend files. 292 29320160306: 294 On amd64, clang 3.8.0 can now insert sections of type AMD64_UNWIND into 295 kernel modules. Therefore, if you load any kernel modules at boot time, 296 please install the boot loaders after you install the kernel, but before 297 rebooting, e.g.: 298 299 make buildworld 300 make kernel KERNCONF=YOUR_KERNEL_HERE 301 make -C sys/boot install 302 <reboot in single user> 303 304 Then follow the usual steps, described in the General Notes section, 305 below. 306 30720160305: 308 Clang, llvm, lldb and compiler-rt have been upgraded to 3.8.0. Please 309 see the 20141231 entry below for information about prerequisites and 310 upgrading, if you are not already using clang 3.5.0 or higher. 311 31220160301: 313 The AIO subsystem is now a standard part of the kernel. The 314 VFS_AIO kernel option and aio.ko kernel module have been removed. 315 Due to stability concerns, asynchronous I/O requests are only 316 permitted on sockets and raw disks by default. To enable 317 asynchronous I/O requests on all file types, set the 318 vfs.aio.enable_unsafe sysctl to a non-zero value. 319 32020160226: 321 The ELF object manipulation tool objcopy is now provided by the 322 ELF Tool Chain project rather than by GNU binutils. It should be a 323 drop-in replacement, with the addition of arm64 support. The 324 (temporary) src.conf knob WITHOUT_ELFCOPY_AS_OBJCOPY knob may be set 325 to obtain the GNU version if necessary. 326 32720160129: 328 Building ZFS pools on top of zvols is prohibited by default. That 329 feature has never worked safely; it's always been prone to deadlocks. 330 Using a zvol as the backing store for a VM guest's virtual disk will 331 still work, even if the guest is using ZFS. Legacy behavior can be 332 restored by setting vfs.zfs.vol.recursive=1. 333 33420160119: 335 The NONE and HPN patches has been removed from OpenSSH. They are 336 still available in the security/openssh-portable port. 337 33820160113: 339 With the addition of ypldap(8), a new _ypldap user is now required 340 during installworld. "mergemaster -p" can be used to add the user 341 prior to installworld, as documented in the handbook. 342 34320151216: 344 The tftp loader (pxeboot) now uses the option root-path directive. As a 345 consequence it no longer looks for a pxeboot.4th file on the tftp 346 server. Instead it uses the regular /boot infrastructure as with the 347 other loaders. 348 34920151211: 350 The code to start recording plug and play data into the modules has 351 been committed. While the old tools will properly build a new kernel, 352 a number of warnings about "unknown metadata record 4" will be produced 353 for an older kldxref. To avoid such warnings, make sure to rebuild 354 the kernel toolchain (or world). Make sure that you have r292078 or 355 later when trying to build 292077 or later before rebuilding. 356 35720151207: 358 Debug data files are now built by default with 'make buildworld' and 359 installed with 'make installworld'. This facilitates debugging but 360 requires more disk space both during the build and for the installed 361 world. Debug files may be disabled by setting WITHOUT_DEBUG_FILES=yes 362 in src.conf(5). 363 36420151130: 365 r291527 changed the internal interface between the nfsd.ko and 366 nfscommon.ko modules. As such, they must both be upgraded to-gether. 367 __FreeBSD_version has been bumped because of this. 368 36920151108: 370 Add support for unicode collation strings leads to a change of 371 order of files listed by ls(1) for example. To get back to the old 372 behaviour, set LC_COLLATE environment variable to "C". 373 374 Databases administrators will need to reindex their databases given 375 collation results will be different. 376 377 Due to a bug in install(1) it is recommended to remove the ancient 378 locales before running make installworld. 379 380 rm -rf /usr/share/locale/* 381 38220151030: 383 The OpenSSL has been upgraded to 1.0.2d. Any binaries requiring 384 libcrypto.so.7 or libssl.so.7 must be recompiled. 385 38620151020: 387 Qlogic 24xx/25xx firmware images were updated from 5.5.0 to 7.3.0. 388 Kernel modules isp_2400_multi and isp_2500_multi were removed and 389 should be replaced with isp_2400 and isp_2500 modules respectively. 390 39120151017: 392 The build previously allowed using 'make -n' to not recurse into 393 sub-directories while showing what commands would be executed, and 394 'make -n -n' to recursively show commands. Now 'make -n' will recurse 395 and 'make -N' will not. 396 39720151012: 398 If you specify SENDMAIL_MC or SENDMAIL_CF in make.conf, mergemaster 399 and etcupdate will now use this file. A custom sendmail.cf is now 400 updated via this mechanism rather than via installworld. If you had 401 excluded sendmail.cf in mergemaster.rc or etcupdate.conf, you may 402 want to remove the exclusion or change it to "always install". 403 /etc/mail/sendmail.cf is now managed the same way regardless of 404 whether SENDMAIL_MC/SENDMAIL_CF is used. If you are not using 405 SENDMAIL_MC/SENDMAIL_CF there should be no change in behavior. 406 40720151011: 408 Compatibility shims for legacy ATA device names have been removed. 409 It includes ATA_STATIC_ID kernel option, kern.cam.ada.legacy_aliases 410 and kern.geom.raid.legacy_aliases loader tunables, kern.devalias.* 411 environment variables, /dev/ad* and /dev/ar* symbolic links. 412 41320151006: 414 Clang, llvm, lldb, compiler-rt and libc++ have been upgraded to 3.7.0. 415 Please see the 20141231 entry below for information about prerequisites 416 and upgrading, if you are not already using clang 3.5.0 or higher. 417 41820150924: 419 Kernel debug files have been moved to /usr/lib/debug/boot/kernel/, 420 and renamed from .symbols to .debug. This reduces the size requirements 421 on the boot partition or file system and provides consistency with 422 userland debug files. 423 424 When using the supported kernel installation method the 425 /usr/lib/debug/boot/kernel directory will be renamed (to kernel.old) 426 as is done with /boot/kernel. 427 428 Developers wishing to maintain the historical behavior of installing 429 debug files in /boot/kernel/ can set KERN_DEBUGDIR="" in src.conf(5). 430 43120150827: 432 The wireless drivers had undergone changes that remove the 'parent 433 interface' from the ifconfig -l output. The rc.d network scripts 434 used to check presence of a parent interface in the list, so old 435 scripts would fail to start wireless networking. Thus, etcupdate(3) 436 or mergemaster(8) run is required after kernel update, to update your 437 rc.d scripts in /etc. 438 43920150827: 440 pf no longer supports 'scrub fragment crop' or 'scrub fragment drop-ovl' 441 These configurations are now automatically interpreted as 442 'scrub fragment reassemble'. 443 44420150817: 445 Kernel-loadable modules for the random(4) device are back. To use 446 them, the kernel must have 447 448 device random 449 options RANDOM_LOADABLE 450 451 kldload(8) can then be used to load random_fortuna.ko 452 or random_yarrow.ko. Please note that due to the indirect 453 function calls that the loadable modules need to provide, 454 the build-in variants will be slightly more efficient. 455 456 The random(4) kernel option RANDOM_DUMMY has been retired due to 457 unpopularity. It was not all that useful anyway. 458 45920150813: 460 The WITHOUT_ELFTOOLCHAIN_TOOLS src.conf(5) knob has been retired. 461 Control over building the ELF Tool Chain tools is now provided by 462 the WITHOUT_TOOLCHAIN knob. 463 46420150810: 465 The polarity of Pulse Per Second (PPS) capture events with the 466 uart(4) driver has been corrected. Prior to this change the PPS 467 "assert" event corresponded to the trailing edge of a positive PPS 468 pulse and the "clear" event was the leading edge of the next pulse. 469 470 As the width of a PPS pulse in a typical GPS receiver is on the 471 order of 1 millisecond, most users will not notice any significant 472 difference with this change. 473 474 Anyone who has compensated for the historical polarity reversal by 475 configuring a negative offset equal to the pulse width will need to 476 remove that workaround. 477 47820150809: 479 The default group assigned to /dev/dri entries has been changed 480 from 'wheel' to 'video' with the id of '44'. If you want to have 481 access to the dri devices please add yourself to the video group 482 with: 483 484 # pw groupmod video -m $USER 485 48620150806: 487 The menu.rc and loader.rc files will now be replaced during 488 upgrades. Please migrate local changes to menu.rc.local and 489 loader.rc.local instead. 490 49120150805: 492 GNU Binutils versions of addr2line, c++filt, nm, readelf, size, 493 strings and strip have been removed. The src.conf(5) knob 494 WITHOUT_ELFTOOLCHAIN_TOOLS no longer provides the binutils tools. 495 49620150728: 497 As ZFS requires more kernel stack pages than is the default on some 498 architectures e.g. i386, it now warns if KSTACK_PAGES is less than 499 ZFS_MIN_KSTACK_PAGES (which is 4 at the time of writing). 500 501 Please consider using 'options KSTACK_PAGES=X' where X is greater 502 than or equal to ZFS_MIN_KSTACK_PAGES i.e. 4 in such configurations. 503 50420150706: 505 sendmail has been updated to 8.15.2. Starting with FreeBSD 11.0 506 and sendmail 8.15, sendmail uses uncompressed IPv6 addresses by 507 default, i.e., they will not contain "::". For example, instead 508 of ::1, it will be 0:0:0:0:0:0:0:1. This permits a zero subnet 509 to have a more specific match, such as different map entries for 510 IPv6:0:0 vs IPv6:0. This change requires that configuration 511 data (including maps, files, classes, custom ruleset, etc.) must 512 use the same format, so make certain such configuration data is 513 upgrading. As a very simple check search for patterns like 514 'IPv6:[0-9a-fA-F:]*::' and 'IPv6::'. To return to the old 515 behavior, set the m4 option confUSE_COMPRESSED_IPV6_ADDRESSES or 516 the cf option UseCompressedIPv6Addresses. 517 51820150630: 519 The default kernel entropy-processing algorithm is now 520 Fortuna, replacing Yarrow. 521 522 Assuming you have 'device random' in your kernel config 523 file, the configurations allow a kernel option to override 524 this default. You may choose *ONE* of: 525 526 options RANDOM_YARROW # Legacy /dev/random algorithm. 527 options RANDOM_DUMMY # Blocking-only driver. 528 529 If you have neither, you get Fortuna. For most people, 530 read no further, Fortuna will give a /dev/random that works 531 like it always used to, and the difference will be irrelevant. 532 533 If you remove 'device random', you get *NO* kernel-processed 534 entropy at all. This may be acceptable to folks building 535 embedded systems, but has complications. Carry on reading, 536 and it is assumed you know what you need. 537 538 *PLEASE* read random(4) and random(9) if you are in the 539 habit of tweaking kernel configs, and/or if you are a member 540 of the embedded community, wanting specific and not-usual 541 behaviour from your security subsystems. 542 543 NOTE!! If you use RANDOM_DUMMY and/or have no 'device 544 random', you will NOT have a functioning /dev/random, and 545 many cryptographic features will not work, including SSH. 546 You may also find strange behaviour from the random(3) set 547 of library functions, in particular sranddev(3), srandomdev(3) 548 and arc4random(3). The reason for this is that the KERN_ARND 549 sysctl only returns entropy if it thinks it has some to 550 share, and with RANDOM_DUMMY or no 'device random' this 551 will never happen. 552 55320150623: 554 An additional fix for the issue described in the 20150614 sendmail 555 entry below has been been committed in revision 284717. 556 55720150616: 558 FreeBSD's old make (fmake) has been removed from the system. It is 559 available as the devel/fmake port or via pkg install fmake. 560 56120150615: 562 The fix for the issue described in the 20150614 sendmail entry 563 below has been been committed in revision 284436. The work 564 around described in that entry is no longer needed unless the 565 default setting is overridden by a confDH_PARAMETERS configuration 566 setting of '5' or pointing to a 512 bit DH parameter file. 567 56820150614: 569 ALLOW_DEPRECATED_ATF_TOOLS/ATFFILE support has been removed from 570 atf.test.mk (included from bsd.test.mk). Please upgrade devel/atf 571 and devel/kyua to version 0.20+ and adjust any calling code to work 572 with Kyuafile and kyua. 573 57420150614: 575 The import of openssl to address the FreeBSD-SA-15:10.openssl 576 security advisory includes a change which rejects handshakes 577 with DH parameters below 768 bits. sendmail releases prior 578 to 8.15.2 (not yet released), defaulted to a 512 bit 579 DH parameter setting for client connections. To work around 580 this interoperability, sendmail can be configured to use a 581 2048 bit DH parameter by: 582 583 1. Edit /etc/mail/`hostname`.mc 584 2. If a setting for confDH_PARAMETERS does not exist or 585 exists and is set to a string beginning with '5', 586 replace it with '2'. 587 3. If a setting for confDH_PARAMETERS exists and is set to 588 a file path, create a new file with: 589 openssl dhparam -out /path/to/file 2048 590 4. Rebuild the .cf file: 591 cd /etc/mail/; make; make install 592 5. Restart sendmail: 593 cd /etc/mail/; make restart 594 595 A sendmail patch is coming, at which time this file will be 596 updated. 597 59820150604: 599 Generation of legacy formatted entries have been disabled by default 600 in pwd_mkdb(8), as all base system consumers of the legacy formatted 601 entries were converted to use the new format by default when the new, 602 machine independent format have been added and supported since FreeBSD 603 5.x. 604 605 Please see the pwd_mkdb(8) manual page for further details. 606 60720150525: 608 Clang and llvm have been upgraded to 3.6.1 release. Please see the 609 20141231 entry below for information about prerequisites and upgrading, 610 if you are not already using 3.5.0 or higher. 611 61220150521: 613 TI platform code switched to using vendor DTS files and this update 614 may break existing systems running on Beaglebone, Beaglebone Black, 615 and Pandaboard: 616 617 - dtb files should be regenerated/reinstalled. Filenames are the 618 same but content is different now 619 - GPIO addressing was changed, now each GPIO bank (32 pins per bank) 620 has its own /dev/gpiocX device, e.g. pin 121 on /dev/gpioc0 in old 621 addressing scheme is now pin 25 on /dev/gpioc3. 622 - Pandaboard: /etc/ttys should be updated, serial console device is 623 now /dev/ttyu2, not /dev/ttyu0 624 62520150501: 626 soelim(1) from gnu/usr.bin/groff has been replaced by usr.bin/soelim. 627 If you need the GNU extension from groff soelim(1), install groff 628 from package: pkg install groff, or via ports: textproc/groff. 629 63020150423: 631 chmod, chflags, chown and chgrp now affect symlinks in -R mode as 632 defined in symlink(7); previously symlinks were silently ignored. 633 63420150415: 635 The const qualifier has been removed from iconv(3) to comply with 636 POSIX. The ports tree is aware of this from r384038 onwards. 637 63820150416: 639 Libraries specified by LIBADD in Makefiles must have a corresponding 640 DPADD_<lib> variable to ensure correct dependencies. This is now 641 enforced in src.libnames.mk. 642 64320150324: 644 From legacy ata(4) driver was removed support for SATA controllers 645 supported by more functional drivers ahci(4), siis(4) and mvs(4). 646 Kernel modules ataahci and ataadaptec were removed completely, 647 replaced by ahci and mvs modules respectively. 648 64920150315: 650 Clang, llvm and lldb have been upgraded to 3.6.0 release. Please see 651 the 20141231 entry below for information about prerequisites and 652 upgrading, if you are not already using 3.5.0 or higher. 653 65420150307: 655 The 32-bit PowerPC kernel has been changed to a position-independent 656 executable. This can only be booted with a version of loader(8) 657 newer than January 31, 2015, so make sure to update both world and 658 kernel before rebooting. 659 66020150217: 661 If you are running a -CURRENT kernel since r273872 (Oct 30th, 2014), 662 but before r278950, the RNG was not seeded properly. Immediately 663 upgrade the kernel to r278950 or later and regenerate any keys (e.g. 664 ssh keys or openssl keys) that were generated w/ a kernel from that 665 range. This does not affect programs that directly used /dev/random 666 or /dev/urandom. All userland uses of arc4random(3) are affected. 667 66820150210: 669 The autofs(4) ABI was changed in order to restore binary compatibility 670 with 10.1-RELEASE. The automountd(8) daemon needs to be rebuilt to work 671 with the new kernel. 672 67320150131: 674 The powerpc64 kernel has been changed to a position-independent 675 executable. This can only be booted with a new version of loader(8), 676 so make sure to update both world and kernel before rebooting. 677 67820150118: 679 Clang and llvm have been upgraded to 3.5.1 release. This is a bugfix 680 only release, no new features have been added. Please see the 20141231 681 entry below for information about prerequisites and upgrading, if you 682 are not already using 3.5.0. 683 68420150107: 685 ELF tools addr2line, elfcopy (strip), nm, size, and strings are now 686 taken from the ELF Tool Chain project rather than GNU binutils. They 687 should be drop-in replacements, with the addition of arm64 support. 688 The WITHOUT_ELFTOOLCHAIN_TOOLS= knob may be used to obtain the 689 binutils tools, if necessary. See 20150805 for updated information. 690 69120150105: 692 The default Unbound configuration now enables remote control 693 using a local socket. Users who have already enabled the 694 local_unbound service should regenerate their configuration 695 by running "service local_unbound setup" as root. 696 69720150102: 698 The GNU texinfo and GNU info pages have been removed. 699 To be able to view GNU info pages please install texinfo from ports. 700 70120141231: 702 Clang, llvm and lldb have been upgraded to 3.5.0 release. 703 704 As of this release, a prerequisite for building clang, llvm and lldb is 705 a C++11 capable compiler and C++11 standard library. This means that to 706 be able to successfully build the cross-tools stage of buildworld, with 707 clang as the bootstrap compiler, your system compiler or cross compiler 708 should either be clang 3.3 or later, or gcc 4.8 or later, and your 709 system C++ library should be libc++, or libdstdc++ from gcc 4.8 or 710 later. 711 712 On any standard FreeBSD 10.x or 11.x installation, where clang and 713 libc++ are on by default (that is, on x86 or arm), this should work out 714 of the box. 715 716 On 9.x installations where clang is enabled by default, e.g. on x86 and 717 powerpc, libc++ will not be enabled by default, so libc++ should be 718 built (with clang) and installed first. If both clang and libc++ are 719 missing, build clang first, then use it to build libc++. 720 721 On 8.x and earlier installations, upgrade to 9.x first, and then follow 722 the instructions for 9.x above. 723 724 Sparc64 and mips users are unaffected, as they still use gcc 4.2.1 by 725 default, and do not build clang. 726 727 Many embedded systems are resource constrained, and will not be able to 728 build clang in a reasonable time, or in some cases at all. In those 729 cases, cross building bootable systems on amd64 is a workaround. 730 731 This new version of clang introduces a number of new warnings, of which 732 the following are most likely to appear: 733 734 -Wabsolute-value 735 736 This warns in two cases, for both C and C++: 737 * When the code is trying to take the absolute value of an unsigned 738 quantity, which is effectively a no-op, and almost never what was 739 intended. The code should be fixed, if at all possible. If you are 740 sure that the unsigned quantity can be safely cast to signed, without 741 loss of information or undefined behavior, you can add an explicit 742 cast, or disable the warning. 743 744 * When the code is trying to take an absolute value, but the called 745 abs() variant is for the wrong type, which can lead to truncation. 746 If you want to disable the warning instead of fixing the code, please 747 make sure that truncation will not occur, or it might lead to unwanted 748 side-effects. 749 750 -Wtautological-undefined-compare and 751 -Wundefined-bool-conversion 752 753 These warn when C++ code is trying to compare 'this' against NULL, while 754 'this' should never be NULL in well-defined C++ code. However, there is 755 some legacy (pre C++11) code out there, which actively abuses this 756 feature, which was less strictly defined in previous C++ versions. 757 758 Squid and openjdk do this, for example. The warning can be turned off 759 for C++98 and earlier, but compiling the code in C++11 mode might result 760 in unexpected behavior; for example, the parts of the program that are 761 unreachable could be optimized away. 762 76320141222: 764 The old NFS client and server (kernel options NFSCLIENT, NFSSERVER) 765 kernel sources have been removed. The .h files remain, since some 766 utilities include them. This will need to be fixed later. 767 If "mount -t oldnfs ..." is attempted, it will fail. 768 If the "-o" option on mountd(8), nfsd(8) or nfsstat(1) is used, 769 the utilities will report errors. 770 77120141121: 772 The handling of LOCAL_LIB_DIRS has been altered to skip addition of 773 directories to top level SUBDIR variable when their parent 774 directory is included in LOCAL_DIRS. Users with build systems with 775 such hierarchies and without SUBDIR entries in the parent 776 directory Makefiles should add them or add the directories to 777 LOCAL_DIRS. 778 77920141109: 780 faith(4) and faithd(8) have been removed from the base system. Faith 781 has been obsolete for a very long time. 782 78320141104: 784 vt(4), the new console driver, is enabled by default. It brings 785 support for Unicode and double-width characters, as well as 786 support for UEFI and integration with the KMS kernel video 787 drivers. 788 789 You may need to update your console settings in /etc/rc.conf, 790 most probably the keymap. During boot, /etc/rc.d/syscons will 791 indicate what you need to do. 792 793 vt(4) still has issues and lacks some features compared to 794 syscons(4). See the wiki for up-to-date information: 795 https://wiki.freebsd.org/Newcons 796 797 If you want to keep using syscons(4), you can do so by adding 798 the following line to /boot/loader.conf: 799 kern.vty=sc 800 80120141102: 802 pjdfstest has been integrated into kyua as an opt-in test suite. 803 Please see share/doc/pjdfstest/README for more details on how to 804 execute it. 805 80620141009: 807 gperf has been removed from the base system for architectures 808 that use clang. Ports that require gperf will obtain it from the 809 devel/gperf port. 810 81120140923: 812 pjdfstest has been moved from tools/regression/pjdfstest to 813 contrib/pjdfstest . 814 81520140922: 816 At svn r271982, The default linux compat kernel ABI has been adjusted 817 to 2.6.18 in support of the linux-c6 compat ports infrastructure 818 update. If you wish to continue using the linux-f10 compat ports, 819 add compat.linux.osrelease=2.6.16 to your local sysctl.conf. Users are 820 encouraged to update their linux-compat packages to linux-c6 during 821 their next update cycle. 822 82320140729: 824 The ofwfb driver, used to provide a graphics console on PowerPC when 825 using vt(4), no longer allows mmap() of all physical memory. This 826 will prevent Xorg on PowerPC with some ATI graphics cards from 827 initializing properly unless x11-servers/xorg-server is updated to 828 1.12.4_8 or newer. 829 83020140723: 831 The xdev targets have been converted to using TARGET and 832 TARGET_ARCH instead of XDEV and XDEV_ARCH. 833 83420140719: 835 The default unbound configuration has been modified to address 836 issues with reverse lookups on networks that use private 837 address ranges. If you use the local_unbound service, run 838 "service local_unbound setup" as root to regenerate your 839 configuration, then "service local_unbound reload" to load the 840 new configuration. 841 84220140709: 843 The GNU texinfo and GNU info pages are not built and installed 844 anymore, WITH_INFO knob has been added to allow to built and install 845 them again. 846 UPDATE: see 20150102 entry on texinfo's removal 847 84820140708: 849 The GNU readline library is now an INTERNALLIB - that is, it is 850 statically linked into consumers (GDB and variants) in the base 851 system, and the shared library is no longer installed. The 852 devel/readline port is available for third party software that 853 requires readline. 854 85520140702: 856 The Itanium architecture (ia64) has been removed from the list of 857 known architectures. This is the first step in the removal of the 858 architecture. 859 86020140701: 861 Commit r268115 has added NFSv4.1 server support, merged from 862 projects/nfsv4.1-server. Since this includes changes to the 863 internal interfaces between the NFS related modules, a full 864 build of the kernel and modules will be necessary. 865 __FreeBSD_version has been bumped. 866 86720140629: 868 The WITHOUT_VT_SUPPORT kernel config knob has been renamed 869 WITHOUT_VT. (The other _SUPPORT knobs have a consistent meaning 870 which differs from the behaviour controlled by this knob.) 871 87220140619: 873 Maximal length of the serial number in CTL was increased from 16 to 874 64 chars, that breaks ABI. All CTL-related tools, such as ctladm 875 and ctld, need to be rebuilt to work with a new kernel. 876 87720140606: 878 The libatf-c and libatf-c++ major versions were downgraded to 0 and 879 1 respectively to match the upstream numbers. They were out of 880 sync because, when they were originally added to FreeBSD, the 881 upstream versions were not respected. These libraries are private 882 and not yet built by default, so renumbering them should be a 883 non-issue. However, unclean source trees will yield broken test 884 programs once the operator executes "make delete-old-libs" after a 885 "make installworld". 886 887 Additionally, the atf-sh binary was made private by moving it into 888 /usr/libexec/. Already-built shell test programs will keep the 889 path to the old binary so they will break after "make delete-old" 890 is run. 891 892 If you are using WITH_TESTS=yes (not the default), wipe the object 893 tree and rebuild from scratch to prevent spurious test failures. 894 This is only needed once: the misnumbered libraries and misplaced 895 binaries have been added to OptionalObsoleteFiles.inc so they will 896 be removed during a clean upgrade. 897 89820140512: 899 Clang and llvm have been upgraded to 3.4.1 release. 900 90120140508: 902 We bogusly installed src.opts.mk in /usr/share/mk. This file should 903 be removed to avoid issues in the future (and has been added to 904 ObsoleteFiles.inc). 905 90620140505: 907 /etc/src.conf now affects only builds of the FreeBSD src tree. In the 908 past, it affected all builds that used the bsd.*.mk files. The old 909 behavior was a bug, but people may have relied upon it. To get this 910 behavior back, you can .include /etc/src.conf from /etc/make.conf 911 (which is still global and isn't changed). This also changes the 912 behavior of incremental builds inside the tree of individual 913 directories. Set MAKESYSPATH to ".../share/mk" to do that. 914 Although this has survived make universe and some upgrade scenarios, 915 other upgrade scenarios may have broken. At least one form of 916 temporary breakage was fixed with MAKESYSPATH settings for buildworld 917 as well... In cases where MAKESYSPATH isn't working with this 918 setting, you'll need to set it to the full path to your tree. 919 920 One side effect of all this cleaning up is that bsd.compiler.mk 921 is no longer implicitly included by bsd.own.mk. If you wish to 922 use COMPILER_TYPE, you must now explicitly include bsd.compiler.mk 923 as well. 924 92520140430: 926 The lindev device has been removed since /dev/full has been made a 927 standard device. __FreeBSD_version has been bumped. 928 92920140424: 930 The knob WITHOUT_VI was added to the base system, which controls 931 building ex(1), vi(1), etc. Older releases of FreeBSD required ex(1) 932 in order to reorder files share/termcap and didn't build ex(1) as a 933 build tool, so building/installing with WITH_VI is highly advised for 934 build hosts for older releases. 935 936 This issue has been fixed in stable/9 and stable/10 in r277022 and 937 r276991, respectively. 938 93920140418: 940 The YES_HESIOD knob has been removed. It has been obsolete for 941 a decade. Please move to using WITH_HESIOD instead or your builds 942 will silently lack HESIOD. 943 94420140405: 945 The uart(4) driver has been changed with respect to its handling 946 of the low-level console. Previously the uart(4) driver prevented 947 any process from changing the baudrate or the CLOCAL and HUPCL 948 control flags. By removing the restrictions, operators can make 949 changes to the serial console port without having to reboot. 950 However, when getty(8) is started on the serial device that is 951 associated with the low-level console, a misconfigured terminal 952 line in /etc/ttys will now have a real impact. 953 Before upgrading the kernel, make sure that /etc/ttys has the 954 serial console device configured as 3wire without baudrate to 955 preserve the previous behaviour. E.g: 956 ttyu0 "/usr/libexec/getty 3wire" vt100 on secure 957 95820140306: 959 Support for libwrap (TCP wrappers) in rpcbind was disabled by default 960 to improve performance. To re-enable it, if needed, run rpcbind 961 with command line option -W. 962 96320140226: 964 Switched back to the GPL dtc compiler due to updates in the upstream 965 dts files not being supported by the BSDL dtc compiler. You will need 966 to rebuild your kernel toolchain to pick up the new compiler. Core dumps 967 may result while building dtb files during a kernel build if you fail 968 to do so. Set WITHOUT_GPL_DTC if you require the BSDL compiler. 969 97020140216: 971 Clang and llvm have been upgraded to 3.4 release. 972 97320140216: 974 The nve(4) driver has been removed. Please use the nfe(4) driver 975 for NVIDIA nForce MCP Ethernet adapters instead. 976 97720140212: 978 An ABI incompatibility crept into the libc++ 3.4 import in r261283. 979 This could cause certain C++ applications using shared libraries built 980 against the previous version of libc++ to crash. The incompatibility 981 has now been fixed, but any C++ applications or shared libraries built 982 between r261283 and r261801 should be recompiled. 983 98420140204: 985 OpenSSH will now ignore errors caused by kernel lacking of Capsicum 986 capability mode support. Please note that enabling the feature in 987 kernel is still highly recommended. 988 98920140131: 990 OpenSSH is now built with sandbox support, and will use sandbox as 991 the default privilege separation method. This requires Capsicum 992 capability mode support in kernel. 993 99420140128: 995 The libelf and libdwarf libraries have been updated to newer 996 versions from upstream. Shared library version numbers for 997 these two libraries were bumped. Any ports or binaries 998 requiring these two libraries should be recompiled. 999 __FreeBSD_version is bumped to 1100006. 1000 100120140110: 1002 If a Makefile in a tests/ directory was auto-generating a Kyuafile 1003 instead of providing an explicit one, this would prevent such 1004 Makefile from providing its own Kyuafile in the future during 1005 NO_CLEAN builds. This has been fixed in the Makefiles but manual 1006 intervention is needed to clean an objdir if you use NO_CLEAN: 1007 # find /usr/obj -name Kyuafile | xargs rm -f 1008 100920131213: 1010 The behavior of gss_pseudo_random() for the krb5 mechanism 1011 has changed, for applications requesting a longer random string 1012 than produced by the underlying enctype's pseudo-random() function. 1013 In particular, the random string produced from a session key of 1014 enctype aes256-cts-hmac-sha1-96 or aes256-cts-hmac-sha1-96 will 1015 be different at the 17th octet and later, after this change. 1016 The counter used in the PRF+ construction is now encoded as a 1017 big-endian integer in accordance with RFC 4402. 1018 __FreeBSD_version is bumped to 1100004. 1019 102020131108: 1021 The WITHOUT_ATF build knob has been removed and its functionality 1022 has been subsumed into the more generic WITHOUT_TESTS. If you were 1023 using the former to disable the build of the ATF libraries, you 1024 should change your settings to use the latter. 1025 102620131025: 1027 The default version of mtree is nmtree which is obtained from 1028 NetBSD. The output is generally the same, but may vary 1029 slightly. If you found you need identical output adding 1030 "-F freebsd9" to the command line should do the trick. For the 1031 time being, the old mtree is available as fmtree. 1032 103320131014: 1034 libbsdyml has been renamed to libyaml and moved to /usr/lib/private. 1035 This will break ports-mgmt/pkg. Rebuild the port, or upgrade to pkg 1036 1.1.4_8 and verify bsdyml not linked in, before running "make 1037 delete-old-libs": 1038 # make -C /usr/ports/ports-mgmt/pkg build deinstall install clean 1039 or 1040 # pkg install pkg; ldd /usr/local/sbin/pkg | grep bsdyml 1041 104220131010: 1043 The stable/10 branch has been created in subversion from head 1044 revision r256279. 1045 104620131010: 1047 The rc.d/jail script has been updated to support jail(8) 1048 configuration file. The "jail_<jname>_*" rc.conf(5) variables 1049 for per-jail configuration are automatically converted to 1050 /var/run/jail.<jname>.conf before the jail(8) utility is invoked. 1051 This is transparently backward compatible. See below about some 1052 incompatibilities and rc.conf(5) manual page for more details. 1053 1054 These variables are now deprecated in favor of jail(8) configuration 1055 file. One can use "rc.d/jail config <jname>" command to generate 1056 a jail(8) configuration file in /var/run/jail.<jname>.conf without 1057 running the jail(8) utility. The default pathname of the 1058 configuration file is /etc/jail.conf and can be specified by 1059 using $jail_conf or $jail_<jname>_conf variables. 1060 1061 Please note that jail_devfs_ruleset accepts an integer at 1062 this moment. Please consider to rewrite the ruleset name 1063 with an integer. 1064 106520130930: 1066 BIND has been removed from the base system. If all you need 1067 is a local resolver, simply enable and start the local_unbound 1068 service instead. Otherwise, several versions of BIND are 1069 available in the ports tree. The dns/bind99 port is one example. 1070 1071 With this change, nslookup(1) and dig(1) are no longer in the base 1072 system. Users should instead use host(1) and drill(1) which are 1073 in the base system. Alternatively, nslookup and dig can 1074 be obtained by installing the dns/bind-tools port. 1075 107620130916: 1077 With the addition of unbound(8), a new unbound user is now 1078 required during installworld. "mergemaster -p" can be used to 1079 add the user prior to installworld, as documented in the handbook. 1080 108120130911: 1082 OpenSSH is now built with DNSSEC support, and will by default 1083 silently trust signed SSHFP records. This can be controlled with 1084 the VerifyHostKeyDNS client configuration setting. DNSSEC support 1085 can be disabled entirely with the WITHOUT_LDNS option in src.conf. 1086 108720130906: 1088 The GNU Compiler Collection and C++ standard library (libstdc++) 1089 are no longer built by default on platforms where clang is the system 1090 compiler. You can enable them with the WITH_GCC and WITH_GNUCXX 1091 options in src.conf. 1092 109320130905: 1094 The PROCDESC kernel option is now part of the GENERIC kernel 1095 configuration and is required for the rwhod(8) to work. 1096 If you are using custom kernel configuration, you should include 1097 'options PROCDESC'. 1098 109920130905: 1100 The API and ABI related to the Capsicum framework was modified 1101 in backward incompatible way. The userland libraries and programs 1102 have to be recompiled to work with the new kernel. This includes the 1103 following libraries and programs, but the whole buildworld is 1104 advised: libc, libprocstat, dhclient, tcpdump, hastd, hastctl, 1105 kdump, procstat, rwho, rwhod, uniq. 1106 110720130903: 1108 AES-NI intrinsic support has been added to gcc. The AES-NI module 1109 has been updated to use this support. A new gcc is required to build 1110 the aesni module on both i386 and amd64. 1111 111220130821: 1113 The PADLOCK_RNG and RDRAND_RNG kernel options are now devices. 1114 Thus "device padlock_rng" and "device rdrand_rng" should be 1115 used instead of "options PADLOCK_RNG" & "options RDRAND_RNG". 1116 111720130813: 1118 WITH_ICONV has been split into two feature sets. WITH_ICONV now 1119 enables just the iconv* functionality and is now on by default. 1120 WITH_LIBICONV_COMPAT enables the libiconv api and link time 1121 compatibility. Set WITHOUT_ICONV to build the old way. 1122 If you have been using WITH_ICONV before, you will very likely 1123 need to turn on WITH_LIBICONV_COMPAT. 1124 112520130806: 1126 INVARIANTS option now enables DEBUG for code with OpenSolaris and 1127 Illumos origin, including ZFS. If you have INVARIANTS in your 1128 kernel configuration, then there is no need to set DEBUG or ZFS_DEBUG 1129 explicitly. 1130 DEBUG used to enable witness(9) tracking of OpenSolaris (mostly ZFS) 1131 locks if WITNESS option was set. Because that generated a lot of 1132 witness(9) reports and all of them were believed to be false 1133 positives, this is no longer done. New option OPENSOLARIS_WITNESS 1134 can be used to achieve the previous behavior. 1135 113620130806: 1137 Timer values in IPv6 data structures now use time_uptime instead 1138 of time_second. Although this is not a user-visible functional 1139 change, userland utilities which directly use them---ndp(8), 1140 rtadvd(8), and rtsold(8) in the base system---need to be updated 1141 to r253970 or later. 1142 114320130802: 1144 find -delete can now delete the pathnames given as arguments, 1145 instead of only files found below them or if the pathname did 1146 not contain any slashes. Formerly, the following error message 1147 would result: 1148 1149 find: -delete: <path>: relative path potentially not safe 1150 1151 Deleting the pathnames given as arguments can be prevented 1152 without error messages using -mindepth 1 or by changing 1153 directory and passing "." as argument to find. This works in the 1154 old as well as the new version of find. 1155 115620130726: 1157 Behavior of devfs rules path matching has been changed. 1158 Pattern is now always matched against fully qualified devfs 1159 path and slash characters must be explicitly matched by 1160 slashes in pattern (FNM_PATHNAME). Rulesets involving devfs 1161 subdirectories must be reviewed. 1162 116320130716: 1164 The default ARM ABI has changed to the ARM EABI. The old ABI is 1165 incompatible with the ARM EABI and all programs and modules will 1166 need to be rebuilt to work with a new kernel. 1167 1168 To keep using the old ABI ensure the WITHOUT_ARM_EABI knob is set. 1169 1170 NOTE: Support for the old ABI will be removed in the future and 1171 users are advised to upgrade. 1172 117320130709: 1174 pkg_install has been disconnected from the build if you really need it 1175 you should add WITH_PKGTOOLS in your src.conf(5). 1176 117720130709: 1178 Most of network statistics structures were changed to be able 1179 keep 64-bits counters. Thus all tools, that work with networking 1180 statistics, must be rebuilt (netstat(1), bsnmpd(1), etc.) 1181 118220130618: 1183 Fix a bug that allowed a tracing process (e.g. gdb) to write 1184 to a memory-mapped file in the traced process's address space 1185 even if neither the traced process nor the tracing process had 1186 write access to that file. 1187 118820130615: 1189 CVS has been removed from the base system. An exact copy 1190 of the code is available from the devel/cvs port. 1191 119220130613: 1193 Some people report the following error after the switch to bmake: 1194 1195 make: illegal option -- J 1196 usage: make [-BPSXeiknpqrstv] [-C directory] [-D variable] 1197 ... 1198 *** [buildworld] Error code 2 1199 1200 this likely due to an old instance of make in 1201 ${MAKEPATH} (${MAKEOBJDIRPREFIX}${.CURDIR}/make.${MACHINE}) 1202 which src/Makefile will use that blindly, if it exists, so if 1203 you see the above error: 1204 1205 rm -rf `make -V MAKEPATH` 1206 1207 should resolve it. 1208 120920130516: 1210 Use bmake by default. 1211 Whereas before one could choose to build with bmake via 1212 -DWITH_BMAKE one must now use -DWITHOUT_BMAKE to use the old 1213 make. The goal is to remove these knobs for 10-RELEASE. 1214 1215 It is worth noting that bmake (like gmake) treats the command 1216 line as the unit of failure, rather than statements within the 1217 command line. Thus '(cd some/where && dosomething)' is safer 1218 than 'cd some/where; dosomething'. The '()' allows consistent 1219 behavior in parallel build. 1220 122120130429: 1222 Fix a bug that allows NFS clients to issue READDIR on files. 1223 122420130426: 1225 The WITHOUT_IDEA option has been removed because 1226 the IDEA patent expired. 1227 122820130426: 1229 The sysctl which controls TRIM support under ZFS has been renamed 1230 from vfs.zfs.trim_disable -> vfs.zfs.trim.enabled and has been 1231 enabled by default. 1232 123320130425: 1234 The mergemaster command now uses the default MAKEOBJDIRPREFIX 1235 rather than creating it's own in the temporary directory in 1236 order allow access to bootstrapped versions of tools such as 1237 install and mtree. When upgrading from version of FreeBSD where 1238 the install command does not support -l, you will need to 1239 install a new mergemaster command if mergemaster -p is required. 1240 This can be accomplished with the command (cd src/usr.sbin/mergemaster 1241 && make install). 1242 124320130404: 1244 Legacy ATA stack, disabled and replaced by new CAM-based one since 1245 FreeBSD 9.0, completely removed from the sources. Kernel modules 1246 atadisk and atapi*, user-level tools atacontrol and burncd are 1247 removed. Kernel option `options ATA_CAM` is now permanently enabled 1248 and removed. 1249 125020130319: 1251 SOCK_CLOEXEC and SOCK_NONBLOCK flags have been added to socket(2) 1252 and socketpair(2). Software, in particular Kerberos, may 1253 automatically detect and use these during building. The resulting 1254 binaries will not work on older kernels. 1255 125620130308: 1257 CTL_DISABLE has also been added to the sparc64 GENERIC (for further 1258 information, see the respective 20130304 entry). 1259 126020130304: 1261 Recent commits to callout(9) changed the size of struct callout, 1262 so the KBI is probably heavily disturbed. Also, some functions 1263 in callout(9)/sleep(9)/sleepqueue(9)/condvar(9) KPIs were replaced 1264 by macros. Every kernel module using it won't load, so rebuild 1265 is requested. 1266 1267 The ctl device has been re-enabled in GENERIC for i386 and amd64, 1268 but does not initialize by default (because of the new CTL_DISABLE 1269 option) to save memory. To re-enable it, remove the CTL_DISABLE 1270 option from the kernel config file or set kern.cam.ctl.disable=0 1271 in /boot/loader.conf. 1272 127320130301: 1274 The ctl device has been disabled in GENERIC for i386 and amd64. 1275 This was done due to the extra memory being allocated at system 1276 initialisation time by the ctl driver which was only used if 1277 a CAM target device was created. This makes a FreeBSD system 1278 unusable on 128MB or less of RAM. 1279 128020130208: 1281 A new compression method (lz4) has been merged to -HEAD. Please 1282 refer to zpool-features(7) for more information. 1283 1284 Please refer to the "ZFS notes" section of this file for information 1285 on upgrading boot ZFS pools. 1286 128720130129: 1288 A BSD-licensed patch(1) variant has been added and is installed 1289 as bsdpatch, being the GNU version the default patch. 1290 To inverse the logic and use the BSD-licensed one as default, 1291 while having the GNU version installed as gnupatch, rebuild 1292 and install world with the WITH_BSD_PATCH knob set. 1293 129420130121: 1295 Due to the use of the new -l option to install(1) during build 1296 and install, you must take care not to directly set the INSTALL 1297 make variable in your /etc/make.conf, /etc/src.conf, or on the 1298 command line. If you wish to use the -C flag for all installs 1299 you may be able to add INSTALL+=-C to /etc/make.conf or 1300 /etc/src.conf. 1301 130220130118: 1303 The install(1) option -M has changed meaning and now takes an 1304 argument that is a file or path to append logs to. In the 1305 unlikely event that -M was the last option on the command line 1306 and the command line contained at least two files and a target 1307 directory the first file will have logs appended to it. The -M 1308 option served little practical purpose in the last decade so its 1309 use is expected to be extremely rare. 1310 131120121223: 1312 After switching to Clang as the default compiler some users of ZFS 1313 on i386 systems started to experience stack overflow kernel panics. 1314 Please consider using 'options KSTACK_PAGES=4' in such configurations. 1315 131620121222: 1317 GEOM_LABEL now mangles label names read from file system metadata. 1318 Mangling affect labels containing spaces, non-printable characters, 1319 '%' or '"'. Device names in /etc/fstab and other places may need to 1320 be updated. 1321 132220121217: 1323 By default, only the 10 most recent kernel dumps will be saved. To 1324 restore the previous behaviour (no limit on the number of kernel dumps 1325 stored in the dump directory) add the following line to /etc/rc.conf: 1326 1327 savecore_flags="" 1328 132920121201: 1330 With the addition of auditdistd(8), a new auditdistd user is now 1331 required during installworld. "mergemaster -p" can be used to 1332 add the user prior to installworld, as documented in the handbook. 1333 133420121117: 1335 The sin6_scope_id member variable in struct sockaddr_in6 is now 1336 filled by the kernel before passing the structure to the userland via 1337 sysctl or routing socket. This means the KAME-specific embedded scope 1338 id in sin6_addr.s6_addr[2] is always cleared in userland application. 1339 This behavior can be controlled by net.inet6.ip6.deembed_scopeid. 1340 __FreeBSD_version is bumped to 1000025. 1341 134220121105: 1343 On i386 and amd64 systems WITH_CLANG_IS_CC is now the default. 1344 This means that the world and kernel will be compiled with clang 1345 and that clang will be installed as /usr/bin/cc, /usr/bin/c++, 1346 and /usr/bin/cpp. To disable this behavior and revert to building 1347 with gcc, compile with WITHOUT_CLANG_IS_CC. Really old versions 1348 of current may need to bootstrap WITHOUT_CLANG first if the clang 1349 build fails (its compatibility window doesn't extend to the 9 stable 1350 branch point). 1351 135220121102: 1353 The IPFIREWALL_FORWARD kernel option has been removed. Its 1354 functionality now turned on by default. 1355 135620121023: 1357 The ZERO_COPY_SOCKET kernel option has been removed and 1358 split into SOCKET_SEND_COW and SOCKET_RECV_PFLIP. 1359 NB: SOCKET_SEND_COW uses the VM page based copy-on-write 1360 mechanism which is not safe and may result in kernel crashes. 1361 NB: The SOCKET_RECV_PFLIP mechanism is useless as no current 1362 driver supports disposeable external page sized mbuf storage. 1363 Proper replacements for both zero-copy mechanisms are under 1364 consideration and will eventually lead to complete removal 1365 of the two kernel options. 1366 136720121023: 1368 The IPv4 network stack has been converted to network byte 1369 order. The following modules need to be recompiled together 1370 with kernel: carp(4), divert(4), gif(4), siftr(4), gre(4), 1371 pf(4), ipfw(4), ng_ipfw(4), stf(4). 1372 137320121022: 1374 Support for non-MPSAFE filesystems was removed from VFS. The 1375 VFS_VERSION was bumped, all filesystem modules shall be 1376 recompiled. 1377 137820121018: 1379 All the non-MPSAFE filesystems have been disconnected from 1380 the build. The full list includes: codafs, hpfs, ntfs, nwfs, 1381 portalfs, smbfs, xfs. 1382 138320121016: 1384 The interface cloning API and ABI has changed. The following 1385 modules need to be recompiled together with kernel: 1386 ipfw(4), pfsync(4), pflog(4), usb(4), wlan(4), stf(4), 1387 vlan(4), disc(4), edsc(4), if_bridge(4), gif(4), tap(4), 1388 faith(4), epair(4), enc(4), tun(4), if_lagg(4), gre(4). 1389 139020121015: 1391 The sdhci driver was split in two parts: sdhci (generic SD Host 1392 Controller logic) and sdhci_pci (actual hardware driver). 1393 No kernel config modifications are required, but if you 1394 load sdhc as a module you must switch to sdhci_pci instead. 1395 139620121014: 1397 Import the FUSE kernel and userland support into base system. 1398 139920121013: 1400 The GNU sort(1) program has been removed since the BSD-licensed 1401 sort(1) has been the default for quite some time and no serious 1402 problems have been reported. The corresponding WITH_GNU_SORT 1403 knob has also gone. 1404 140520121006: 1406 The pfil(9) API/ABI for AF_INET family has been changed. Packet 1407 filtering modules: pf(4), ipfw(4), ipfilter(4) need to be recompiled 1408 with new kernel. 1409 141020121001: 1411 The net80211(4) ABI has been changed to allow for improved driver 1412 PS-POLL and power-save support. All wireless drivers need to be 1413 recompiled to work with the new kernel. 1414 141520120913: 1416 The random(4) support for the VIA hardware random number 1417 generator (`PADLOCK') is no longer enabled unconditionally. 1418 Add the padlock_rng device in the custom kernel config if 1419 needed. The GENERIC kernels on i386 and amd64 do include the 1420 device, so the change only affects the custom kernel 1421 configurations. 1422 142320120908: 1424 The pf(4) packet filter ABI has been changed. pfctl(8) and 1425 snmp_pf module need to be recompiled to work with new kernel. 1426 142720120828: 1428 A new ZFS feature flag "com.delphix:empty_bpobj" has been merged 1429 to -HEAD. Pools that have empty_bpobj in active state can not be 1430 imported read-write with ZFS implementations that do not support 1431 this feature. For more information read the zpool-features(5) 1432 manual page. 1433 143420120727: 1435 The sparc64 ZFS loader has been changed to no longer try to auto- 1436 detect ZFS providers based on diskN aliases but now requires these 1437 to be explicitly listed in the OFW boot-device environment variable. 1438 143920120712: 1440 The OpenSSL has been upgraded to 1.0.1c. Any binaries requiring 1441 libcrypto.so.6 or libssl.so.6 must be recompiled. Also, there are 1442 configuration changes. Make sure to merge /etc/ssl/openssl.cnf. 1443 144420120712: 1445 The following sysctls and tunables have been renamed for consistency 1446 with other variables: 1447 kern.cam.da.da_send_ordered -> kern.cam.da.send_ordered 1448 kern.cam.ada.ada_send_ordered -> kern.cam.ada.send_ordered 1449 145020120628: 1451 The sort utility has been replaced with BSD sort. For now, GNU sort 1452 is also available as "gnusort" or the default can be set back to 1453 GNU sort by setting WITH_GNU_SORT. In this case, BSD sort will be 1454 installed as "bsdsort". 1455 145620120611: 1457 A new version of ZFS (pool version 5000) has been merged to -HEAD. 1458 Starting with this version the old system of ZFS pool versioning 1459 is superseded by "feature flags". This concept enables forward 1460 compatibility against certain future changes in functionality of ZFS 1461 pools. The first read-only compatible "feature flag" for ZFS pools 1462 is named "com.delphix:async_destroy". For more information 1463 read the new zpool-features(5) manual page. 1464 Please refer to the "ZFS notes" section of this file for information 1465 on upgrading boot ZFS pools. 1466 146720120417: 1468 The malloc(3) implementation embedded in libc now uses sources imported 1469 as contrib/jemalloc. The most disruptive API change is to 1470 /etc/malloc.conf. If your system has an old-style /etc/malloc.conf, 1471 delete it prior to installworld, and optionally re-create it using the 1472 new format after rebooting. See malloc.conf(5) for details 1473 (specifically the TUNING section and the "opt.*" entries in the MALLCTL 1474 NAMESPACE section). 1475 147620120328: 1477 Big-endian MIPS TARGET_ARCH values no longer end in "eb". mips64eb 1478 is now spelled mips64. mipsn32eb is now spelled mipsn32. mipseb is 1479 now spelled mips. This is to aid compatibility with third-party 1480 software that expects this naming scheme in uname(3). Little-endian 1481 settings are unchanged. If you are updating a big-endian mips64 machine 1482 from before this change, you may need to set MACHINE_ARCH=mips64 in 1483 your environment before the new build system will recognize your machine. 1484 148520120306: 1486 Disable by default the option VFS_ALLOW_NONMPSAFE for all supported 1487 platforms. 1488 148920120229: 1490 Now unix domain sockets behave "as expected" on nullfs(5). Previously 1491 nullfs(5) did not pass through all behaviours to the underlying layer, 1492 as a result if we bound to a socket on the lower layer we could connect 1493 only to the lower path; if we bound to the upper layer we could connect 1494 only to the upper path. The new behavior is one can connect to both the 1495 lower and the upper paths regardless what layer path one binds to. 1496 149720120211: 1498 The getifaddrs upgrade path broken with 20111215 has been restored. 1499 If you have upgraded in between 20111215 and 20120209 you need to 1500 recompile libc again with your kernel. You still need to recompile 1501 world to be able to configure CARP but this restriction already 1502 comes from 20111215. 1503 150420120114: 1505 The set_rcvar() function has been removed from /etc/rc.subr. All 1506 base and ports rc.d scripts have been updated, so if you have a 1507 port installed with a script in /usr/local/etc/rc.d you can either 1508 hand-edit the rcvar= line, or reinstall the port. 1509 1510 An easy way to handle the mass-update of /etc/rc.d: 1511 rm /etc/rc.d/* && mergemaster -i 1512 151320120109: 1514 panic(9) now stops other CPUs in the SMP systems, disables interrupts 1515 on the current CPU and prevents other threads from running. 1516 This behavior can be reverted using the kern.stop_scheduler_on_panic 1517 tunable/sysctl. 1518 The new behavior can be incompatible with kern.sync_on_panic. 1519 152020111215: 1521 The carp(4) facility has been changed significantly. Configuration 1522 of the CARP protocol via ifconfig(8) has changed, as well as format 1523 of CARP events submitted to devd(8) has changed. See manual pages 1524 for more information. The arpbalance feature of carp(4) is currently 1525 not supported anymore. 1526 1527 Size of struct in_aliasreq, struct in6_aliasreq has changed. User 1528 utilities using SIOCAIFADDR, SIOCAIFADDR_IN6, e.g. ifconfig(8), 1529 need to be recompiled. 1530 153120111122: 1532 The acpi_wmi(4) status device /dev/wmistat has been renamed to 1533 /dev/wmistat0. 1534 153520111108: 1536 The option VFS_ALLOW_NONMPSAFE option has been added in order to 1537 explicitely support non-MPSAFE filesystems. 1538 It is on by default for all supported platform at this present 1539 time. 1540 154120111101: 1542 The broken amd(4) driver has been replaced with esp(4) in the amd64, 1543 i386 and pc98 GENERIC kernel configuration files. 1544 154520110930: 1546 sysinstall has been removed 1547 154820110923: 1549 The stable/9 branch created in subversion. This corresponds to the 1550 RELENG_9 branch in CVS. 1551 1552COMMON ITEMS: 1553 1554 General Notes 1555 ------------- 1556 Avoid using make -j when upgrading. While generally safe, there are 1557 sometimes problems using -j to upgrade. If your upgrade fails with 1558 -j, please try again without -j. From time to time in the past there 1559 have been problems using -j with buildworld and/or installworld. This 1560 is especially true when upgrading between "distant" versions (eg one 1561 that cross a major release boundary or several minor releases, or when 1562 several months have passed on the -current branch). 1563 1564 Sometimes, obscure build problems are the result of environment 1565 poisoning. This can happen because the make utility reads its 1566 environment when searching for values for global variables. To run 1567 your build attempts in an "environmental clean room", prefix all make 1568 commands with 'env -i '. See the env(1) manual page for more details. 1569 1570 When upgrading from one major version to another it is generally best 1571 to upgrade to the latest code in the currently installed branch first, 1572 then do an upgrade to the new branch. This is the best-tested upgrade 1573 path, and has the highest probability of being successful. Please try 1574 this approach before reporting problems with a major version upgrade. 1575 1576 When upgrading a live system, having a root shell around before 1577 installing anything can help undo problems. Not having a root shell 1578 around can lead to problems if pam has changed too much from your 1579 starting point to allow continued authentication after the upgrade. 1580 1581 This file should be read as a log of events. When a later event changes 1582 information of a prior event, the prior event should not be deleted. 1583 Instead, a pointer to the entry with the new information should be 1584 placed in the old entry. Readers of this file should also sanity check 1585 older entries before relying on them blindly. Authors of new entries 1586 should write them with this in mind. 1587 1588 ZFS notes 1589 --------- 1590 When upgrading the boot ZFS pool to a new version, always follow 1591 these two steps: 1592 1593 1.) recompile and reinstall the ZFS boot loader and boot block 1594 (this is part of "make buildworld" and "make installworld") 1595 1596 2.) update the ZFS boot block on your boot drive 1597 1598 The following example updates the ZFS boot block on the first 1599 partition (freebsd-boot) of a GPT partitioned drive ada0: 1600 "gpart bootcode -p /boot/gptzfsboot -i 1 ada0" 1601 1602 Non-boot pools do not need these updates. 1603 1604 To build a kernel 1605 ----------------- 1606 If you are updating from a prior version of FreeBSD (even one just 1607 a few days old), you should follow this procedure. It is the most 1608 failsafe as it uses a /usr/obj tree with a fresh mini-buildworld, 1609 1610 make kernel-toolchain 1611 make -DALWAYS_CHECK_MAKE buildkernel KERNCONF=YOUR_KERNEL_HERE 1612 make -DALWAYS_CHECK_MAKE installkernel KERNCONF=YOUR_KERNEL_HERE 1613 1614 To test a kernel once 1615 --------------------- 1616 If you just want to boot a kernel once (because you are not sure 1617 if it works, or if you want to boot a known bad kernel to provide 1618 debugging information) run 1619 make installkernel KERNCONF=YOUR_KERNEL_HERE KODIR=/boot/testkernel 1620 nextboot -k testkernel 1621 1622 To just build a kernel when you know that it won't mess you up 1623 -------------------------------------------------------------- 1624 This assumes you are already running a CURRENT system. Replace 1625 ${arch} with the architecture of your machine (e.g. "i386", 1626 "arm", "amd64", "ia64", "pc98", "sparc64", "powerpc", "mips", etc). 1627 1628 cd src/sys/${arch}/conf 1629 config KERNEL_NAME_HERE 1630 cd ../compile/KERNEL_NAME_HERE 1631 make depend 1632 make 1633 make install 1634 1635 If this fails, go to the "To build a kernel" section. 1636 1637 To rebuild everything and install it on the current system. 1638 ----------------------------------------------------------- 1639 # Note: sometimes if you are running current you gotta do more than 1640 # is listed here if you are upgrading from a really old current. 1641 1642 <make sure you have good level 0 dumps> 1643 make buildworld 1644 make kernel KERNCONF=YOUR_KERNEL_HERE 1645 [1] 1646 <reboot in single user> [3] 1647 mergemaster -Fp [5] 1648 make installworld 1649 mergemaster -Fi [4] 1650 make delete-old [6] 1651 <reboot> 1652 1653 To cross-install current onto a separate partition 1654 -------------------------------------------------- 1655 # In this approach we use a separate partition to hold 1656 # current's root, 'usr', and 'var' directories. A partition 1657 # holding "/", "/usr" and "/var" should be about 2GB in 1658 # size. 1659 1660 <make sure you have good level 0 dumps> 1661 <boot into -stable> 1662 make buildworld 1663 make buildkernel KERNCONF=YOUR_KERNEL_HERE 1664 <maybe newfs current's root partition> 1665 <mount current's root partition on directory ${CURRENT_ROOT}> 1666 make installworld DESTDIR=${CURRENT_ROOT} -DDB_FROM_SRC 1667 make distribution DESTDIR=${CURRENT_ROOT} # if newfs'd 1668 make installkernel KERNCONF=YOUR_KERNEL_HERE DESTDIR=${CURRENT_ROOT} 1669 cp /etc/fstab ${CURRENT_ROOT}/etc/fstab # if newfs'd 1670 <edit ${CURRENT_ROOT}/etc/fstab to mount "/" from the correct partition> 1671 <reboot into current> 1672 <do a "native" rebuild/install as described in the previous section> 1673 <maybe install compatibility libraries from ports/misc/compat*> 1674 <reboot> 1675 1676 1677 To upgrade in-place from stable to current 1678 ---------------------------------------------- 1679 <make sure you have good level 0 dumps> 1680 make buildworld [9] 1681 make kernel KERNCONF=YOUR_KERNEL_HERE [8] 1682 [1] 1683 <reboot in single user> [3] 1684 mergemaster -Fp [5] 1685 make installworld 1686 mergemaster -Fi [4] 1687 make delete-old [6] 1688 <reboot> 1689 1690 Make sure that you've read the UPDATING file to understand the 1691 tweaks to various things you need. At this point in the life 1692 cycle of current, things change often and you are on your own 1693 to cope. The defaults can also change, so please read ALL of 1694 the UPDATING entries. 1695 1696 Also, if you are tracking -current, you must be subscribed to 1697 freebsd-current@freebsd.org. Make sure that before you update 1698 your sources that you have read and understood all the recent 1699 messages there. If in doubt, please track -stable which has 1700 much fewer pitfalls. 1701 1702 [1] If you have third party modules, such as vmware, you 1703 should disable them at this point so they don't crash your 1704 system on reboot. 1705 1706 [3] From the bootblocks, boot -s, and then do 1707 fsck -p 1708 mount -u / 1709 mount -a 1710 cd src 1711 adjkerntz -i # if CMOS is wall time 1712 Also, when doing a major release upgrade, it is required that 1713 you boot into single user mode to do the installworld. 1714 1715 [4] Note: This step is non-optional. Failure to do this step 1716 can result in a significant reduction in the functionality of the 1717 system. Attempting to do it by hand is not recommended and those 1718 that pursue this avenue should read this file carefully, as well 1719 as the archives of freebsd-current and freebsd-hackers mailing lists 1720 for potential gotchas. The -U option is also useful to consider. 1721 See mergemaster(8) for more information. 1722 1723 [5] Usually this step is a noop. However, from time to time 1724 you may need to do this if you get unknown user in the following 1725 step. It never hurts to do it all the time. You may need to 1726 install a new mergemaster (cd src/usr.sbin/mergemaster && make 1727 install) after the buildworld before this step if you last updated 1728 from current before 20130425 or from -stable before 20130430. 1729 1730 [6] This only deletes old files and directories. Old libraries 1731 can be deleted by "make delete-old-libs", but you have to make 1732 sure that no program is using those libraries anymore. 1733 1734 [8] In order to have a kernel that can run the 4.x binaries needed to 1735 do an installworld, you must include the COMPAT_FREEBSD4 option in 1736 your kernel. Failure to do so may leave you with a system that is 1737 hard to boot to recover. A similar kernel option COMPAT_FREEBSD5 is 1738 required to run the 5.x binaries on more recent kernels. And so on 1739 for COMPAT_FREEBSD6 and COMPAT_FREEBSD7. 1740 1741 Make sure that you merge any new devices from GENERIC since the 1742 last time you updated your kernel config file. 1743 1744 [9] When checking out sources, you must include the -P flag to have 1745 cvs prune empty directories. 1746 1747 If CPUTYPE is defined in your /etc/make.conf, make sure to use the 1748 "?=" instead of the "=" assignment operator, so that buildworld can 1749 override the CPUTYPE if it needs to. 1750 1751 MAKEOBJDIRPREFIX must be defined in an environment variable, and 1752 not on the command line, or in /etc/make.conf. buildworld will 1753 warn if it is improperly defined. 1754FORMAT: 1755 1756This file contains a list, in reverse chronological order, of major 1757breakages in tracking -current. It is not guaranteed to be a complete 1758list of such breakages, and only contains entries since September 23, 2011. 1759If you need to see UPDATING entries from before that date, you will need 1760to fetch an UPDATING file from an older FreeBSD release. 1761 1762Copyright information: 1763 1764Copyright 1998-2009 M.
