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/updating-src.html 10 11Items affecting the ports and packages system can be found in 12/usr/ports/UPDATING. Please read that file before running portupgrade. 13 14NOTE: FreeBSD has switched from gcc to clang. If you have trouble bootstrapping 15from older versions of FreeBSD, try WITHOUT_CLANG and WITH_GCC to bootstrap to 16the tip of head, and then rebuild without this option. The bootstrap process 17from older version of current across the gcc/clang cutover is a bit fragile. 18 19NOTE TO PEOPLE WHO THINK THAT FreeBSD 12.x IS SLOW: 20 FreeBSD 12.x has many debugging features turned on, in both the kernel 21 and userland. These features attempt to detect incorrect use of 22 system primitives, and encourage loud failure through extra sanity 23 checking and fail stop semantics. They also substantially impact 24 system performance. If you want to do performance measurement, 25 benchmarking, and optimization, you'll want to turn them off. This 26 includes various WITNESS- related kernel options, INVARIANTS, malloc 27 debugging flags in userland, and various verbose features in the 28 kernel. Many developers choose to disable these features on build 29 machines to maximize performance. (To completely disable malloc 30 debugging, define MALLOC_PRODUCTION in /etc/make.conf, or to merely 31 disable the most expensive debugging functionality run 32 "ln -s 'abort:false,junk:false' /etc/malloc.conf".) 33 34 35****************************** SPECIAL WARNING: ****************************** 36 37 Due to a bug in some versions of clang that's very hard to workaround in 38 the upgrade process, to upgrade to -current you must first upgrade 39 either stable/9 after r286035 or stable/10 after r286033 (including 40 10.3-RELEASE) or current after r286007 (including stable/11 and 41 11.0-RELEASE). These revisions post-date the 10.2 and 9.3 releases, so 42 you'll need to take the unusual step of upgrading to the tip of the 43 stable branch before moving to 11 or -current via a source upgrade. 44 stable/11 and 11.0-RELEASE have working newer compiler. This differs 45 from the historical situation where one could upgrade from anywhere on 46 the last couple of stable branches, so be careful. 47 48 If you're running a hybrid system on 9.x or 10.x with an updated clang 49 compiler or are using an supported external toolchain, the build system 50 will allow the upgrade. Otherwise it will print a reminder. 51 52****************************** SPECIAL WARNING: ****************************** 53 5420170912: 55 The default serial number format for CTL LUNs has changed. This will 56 affect users who use /dev/diskid/* device nodes, or whose FibreChannel 57 or iSCSI clients care about their LUNs' serial numbers. Users who 58 require serial number stability should hardcode serial numbers in 59 /etc/ctl.conf . 60 6120170912: 62 For 32-bit arm compiled for hard-float support, soft-floating point 63 binaries now always get their shared libraries from 64 LD_SOFT_LIBRARY_PATH (in the past, this was only used if 65 /usr/libsoft also existed). Only users with a hard-float ld.so, but 66 soft-float everything else should be affected. 67 6820170826: 69 The geli password typed at boot is now hidden. To restore the previous 70 behavior, see geli(8) for configuration options. 71 7220170825: 73 Move PMTUD blackhole counters to TCPSTATS and remove them from bare 74 sysctl values. Minor nit, but requires a rebuild of both world/kernel 75 to complete. 76 7720170814: 78 "make check" behavior (made in ^/head@r295380) has been changed to 79 execute from a limited sandbox, as opposed to executing from 80 ${TESTSDIR}. 81 82 Behavioral changes: 83 - The "beforecheck" and "aftercheck" targets are now specified. 84 - ${CHECKDIR} (added in commit noted above) has been removed. 85 - Legacy behavior can be enabled by setting 86 WITHOUT_MAKE_CHECK_USE_SANDBOX in src.conf(5) or the environment. 87 88 If the limited sandbox mode is enabled, "make check" will execute 89 "make distribution", then install, execute the tests, and clean up the 90 sandbox if successful. 91 92 The "make distribution" and "make install" targets are typically run as 93 root to set appropriate permissions and ownership at installation time. 94 The end-user should set "WITH_INSTALL_AS_USER" in src.conf(5) or the 95 environment if executing "make check" with limited sandbox mode using 96 an unprivileged user. 97 9820170808: 99 Since the switch to GPT disk labels, fsck for UFS/FFS has been 100 unable to automatically find alternate superblocks. As of r322297, 101 the information needed to find alternate superblocks has been 102 moved to the end of the area reserved for the boot block. 103 Filesystems created with a newfs of this vintage or later 104 will create the recovery information. If you have a filesystem 105 created prior to this change and wish to have a recovery block 106 created for your filesystem, you can do so by running fsck in 107 forground mode (i.e., do not use the -p or -y options). As it 108 starts, fsck will ask ``SAVE DATA TO FIND ALTERNATE SUPERBLOCKS'' 109 to which you should answer yes. 110 11120170728: 112 As of r321665, an NFSv4 server configuration that services 113 Kerberos mounts or clients that do not support the uid/gid in 114 owner/owner_group string capability, must explicitly enable 115 the nfsuserd daemon by adding nfsuserd_enable="YES" to the 116 machine's /etc/rc.conf file. 117 11820170722: 119 Clang, llvm, lldb, compiler-rt and libc++ have been upgraded to 5.0.0. 120 Please see the 20141231 entry below for information about prerequisites 121 and upgrading, if you are not already using clang 3.5.0 or higher. 122 12320170701: 124 WITHOUT_RCMDS is now the default. Set WITH_RCMDS if you need the 125 r-commands (rlogin, rsh, etc.) to be built with the base system. 126 12720170625: 128 The FreeBSD/powerpc platform now uses a 64-bit type for time_t. This is 129 a very major ABI incompatible change, so users of FreeBSD/powerpc must 130 be careful when performing source upgrades. It is best to run 131 'make installworld' from an alternate root system, either a live 132 CD/memory stick, or a temporary root partition. Additionally, all ports 133 must be recompiled. powerpc64 is largely unaffected, except in the case 134 of 32-bit compatibility. All 32-bit binaries will be affected. 135 13620170623: 137 Forward compatibility for the "ino64" project have been committed. This 138 will allow most new binaries to run on older kernels in a limited 139 fashion. This prevents many of the common foot-shooting actions in the 140 upgrade as well as the limited ability to roll back the kernel across 141 the ino64 upgrade. Complicated use cases may not work properly, though 142 enough simpler ones work to allow recovery in most situations. 143 14420170620: 145 Switch back to the BSDL dtc (Device Tree Compiler). Set WITH_GPL_DTC 146 if you require the GPL compiler. 147 14820170618: 149 The internal ABI used for communication between the NFS kernel modules 150 was changed by r320085, so __FreeBSD_version was bumped to 151 ensure all the NFS related modules are updated together. 152 15320170617: 154 The ABI of struct event was changed by extending the data 155 member to 64bit and adding ext fields. For upgrade, same 156 precautions as for the entry 20170523 "ino64" must be 157 followed. 158 15920170531: 160 The GNU roff toolchain has been removed from base. To render manpages 161 which are not supported by mandoc(1), man(1) can fallback on GNU roff 162 from ports (and recommends to install it). 163 To render roff(7) documents, consider using GNU roff from ports or the 164 heirloom doctools roff toolchain from ports via pkg install groff or 165 via pkg install heirloom-doctools. 166 16720170524: 168 The ath(4) and ath_hal(4) modules now build piecemeal to allow for 169 smaller runtime footprint builds. This is useful for embedded systems 170 which only require one chipset support. 171 172 If you load it as a module, make sure this is in /boot/loader.conf: 173 174 if_ath_load="YES" 175 176 This will load the HAL, all chip/RF backends and if_ath_pci. 177 If you have if_ath_pci in /boot/loader.conf, ensure it is after 178 if_ath or it will not load any HAL chipset support. 179 180 If you want to selectively load things (eg on ye cheape ARM/MIPS 181 platforms where RAM is at a premium) you should: 182 183 * load ath_hal 184 * load the chip modules in question 185 * load ath_rate, ath_dfs 186 * load ath_main 187 * load if_ath_pci and/or if_ath_ahb depending upon your particular 188 bus bind type - this is where probe/attach is done. 189 190 For further comments/feedback, poke adrian@ . 191 19220170523: 193 The "ino64" 64-bit inode project has been committed, which extends 194 a number of types to 64 bits. Upgrading in place requires care and 195 adherence to the documented upgrade procedure. 196 197 If using a custom kernel configuration ensure that the 198 COMPAT_FREEBSD11 option is included (as during the upgrade the 199 system will be running the ino64 kernel with the existing world). 200 201 For the safest in-place upgrade begin by removing previous build 202 artifacts via "rm -rf /usr/obj/*". Then, carefully follow the 203 full procedure documented below under the heading "To rebuild 204 everything and install it on the current system." Specifically, 205 a reboot is required after installing the new kernel before 206 installing world. 207 20820170424: 209 The NATM framework including the en(4), fatm(4), hatm(4), and 210 patm(4) devices has been removed. Consumers should plan a 211 migration before the end-of-life date for FreeBSD 11. 212 21320170420: 214 GNU diff has been replaced by a BSD licensed diff. Some features of GNU 215 diff has not been implemented, if those are needed a newer version of 216 GNU diff is available via the diffutils package under the gdiff name. 217 21820170413: 219 As of r316810 for ipfilter, keep frags is no longer assumed when 220 keep state is specified in a rule. r316810 aligns ipfilter with 221 documentation in man pages separating keep frags from keep state. 222 This allows keep state to be specified without forcing keep frags 223 and allows keep frags to be specified independently of keep state. 224 To maintain previous behaviour, also specify keep frags with 225 keep state (as documented in ipf.conf.5). 226 22720170407: 228 arm64 builds now use the base system LLD 4.0.0 linker by default, 229 instead of requiring that the aarch64-binutils port or package be 230 installed. To continue using aarch64-binutils, set 231 CROSS_BINUTILS_PREFIX=/usr/local/aarch64-freebsd/bin . 232 23320170405: 234 The UDP optimization in entry 20160818 that added the sysctl 235 net.inet.udp.require_l2_bcast has been reverted. L2 broadcast 236 packets will no longer be treated as L3 broadcast packets. 237 23820170331: 239 Binds and sends to the loopback addresses, IPv6 and IPv4, will now 240 use any explicitly assigned loopback address available in the jail 241 instead of using the first assigned address of the jail. 242 24320170329: 244 The ctl.ko module no longer implements the iSCSI target frontend: 245 cfiscsi.ko does instead. 246 247 If building cfiscsi.ko as a kernel module, the module can be loaded 248 via one of the following methods: 249 - `cfiscsi_load="YES"` in loader.conf(5). 250 - Add `cfiscsi` to `$kld_list` in rc.conf(5). 251 - ctladm(8)/ctld(8), when compiled with iSCSI support 252 (`WITH_ISCSI=yes` in src.conf(5)) 253 254 Please see cfiscsi(4) for more details. 255 25620170316: 257 The mmcsd.ko module now additionally depends on geom_flashmap.ko. 258 Also, mmc.ko and mmcsd.ko need to be a matching pair built from the 259 same source (previously, the dependency of mmcsd.ko on mmc.ko was 260 missing, but mmcsd.ko now will refuse to load if it is incompatible 261 with mmc.ko). 262 26320170315: 264 The syntax of ipfw(8) named states was changed to avoid ambiguity. 265 If you have used named states in the firewall rules, you need to modify 266 them after installworld and before rebooting. Now named states must 267 be prefixed with colon. 268 26920170311: 270 The old drm (sys/dev/drm/) drivers for i915 and radeon have been 271 removed as the userland we provide cannot use them. The KMS version 272 (sys/dev/drm2) supports the same hardware. 273 27420170302: 275 Clang, llvm, lldb, compiler-rt and libc++ have been upgraded to 4.0.0. 276 Please see the 20141231 entry below for information about prerequisites 277 and upgrading, if you are not already using clang 3.5.0 or higher. 278 27920170221: 280 The code that provides support for ZFS .zfs/ directory functionality 281 has been reimplemented. It's not possible now to create a snapshot 282 by mkdir under .zfs/snapshot/. That should be the only user visible 283 change. 284 28520170216: 286 EISA bus support has been removed. The WITH_EISA option is no longer 287 valid. 288 28920170215: 290 MCA bus support has been removed. 291 29220170127: 293 The WITH_LLD_AS_LD / WITHOUT_LLD_AS_LD build knobs have been renamed 294 WITH_LLD_IS_LD / WITHOUT_LLD_IS_LD, for consistency with CLANG_IS_CC. 295 29620170112: 297 The EM_MULTIQUEUE kernel configuration option is deprecated now that 298 the em(4) driver conforms to iflib specifications. 299 30020170109: 301 The igb(4), em(4) and lem(4) ethernet drivers are now implemented via 302 IFLIB. If you have a custom kernel configuration that excludes em(4) 303 but you use igb(4), you need to re-add em(4) to your custom configuration. 304 30520161217: 306 Clang, llvm, lldb, compiler-rt and libc++ have been upgraded to 3.9.1. 307 Please see the 20141231 entry below for information about prerequisites 308 and upgrading, if you are not already using clang 3.5.0 or higher. 309 31020161124: 311 Clang, llvm, lldb, compiler-rt and libc++ have been upgraded to 3.9.0. 312 Please see the 20141231 entry below for information about prerequisites 313 and upgrading, if you are not already using clang 3.5.0 or higher. 314 31520161119: 316 The layout of the pmap structure has changed for powerpc to put the pmap 317 statistics at the front for all CPU variations. libkvm(3) and all tools 318 that link against it need to be recompiled. 319 32020161030: 321 isl(4) and cyapa(4) drivers now require a new driver, 322 chromebook_platform(4), to work properly on Chromebook-class hardware. 323 On other types of hardware the drivers may need to be configured using 324 device hints. Please see the corresponding manual pages for details. 325 32620161017: 327 The urtwn(4) driver was merged into rtwn(4) and now consists of 328 rtwn(4) main module + rtwn_usb(4) and rtwn_pci(4) bus-specific 329 parts. 330 Also, firmware for RTL8188CE was renamed due to possible name 331 conflict (rtwnrtl8192cU(B) -> rtwnrtl8192cE(B)) 332 33320161015: 334 GNU rcs has been removed from base. It is available as packages: 335 - rcs: Latest GPLv3 GNU rcs version. 336 - rcs57: Copy of the latest version of GNU rcs (GPLv2) before it was 337 removed from base. 338 33920161008: 340 Use of the cc_cdg, cc_chd, cc_hd, or cc_vegas congestion control 341 modules now requires that the kernel configuration contain the 342 TCP_HHOOK option. (This option is included in the GENERIC kernel.) 343 34420161003: 345 The WITHOUT_ELFCOPY_AS_OBJCOPY src.conf(5) knob has been retired. 346 ELF Tool Chain's elfcopy is always installed as /usr/bin/objcopy. 347 34820160924: 349 Relocatable object files with the extension of .So have been renamed 350 to use an extension of .pico instead. The purpose of this change is 351 to avoid a name clash with shared libraries on case-insensitive file 352 systems. On those file systems, foo.So is the same file as foo.so. 353 35420160918: 355 GNU rcs has been turned off by default. It can (temporarily) be built 356 again by adding WITH_RCS knob in src.conf. 357 Otherwise, GNU rcs is available from packages: 358 - rcs: Latest GPLv3 GNU rcs version. 359 - rcs57: Copy of the latest version of GNU rcs (GPLv2) from base. 360 36120160918: 362 The backup_uses_rcs functionality has been removed from rc.subr. 363 36420160908: 365 The queue(3) debugging macro, QUEUE_MACRO_DEBUG, has been split into 366 two separate components, QUEUE_MACRO_DEBUG_TRACE and 367 QUEUE_MACRO_DEBUG_TRASH. Define both for the original 368 QUEUE_MACRO_DEBUG behavior. 369 37020160824: 371 r304787 changed some ioctl interfaces between the iSCSI userspace 372 programs and the kernel. ctladm, ctld, iscsictl, and iscsid must be 373 rebuilt to work with new kernels. __FreeBSD_version has been bumped 374 to 1200005. 375 37620160818: 377 The UDP receive code has been updated to only treat incoming UDP 378 packets that were addressed to an L2 broadcast address as L3 379 broadcast packets. It is not expected that this will affect any 380 standards-conforming UDP application. The new behaviour can be 381 disabled by setting the sysctl net.inet.udp.require_l2_bcast to 382 0. 383 38420160818: 385 Remove the openbsd_poll system call. 386 __FreeBSD_version has been bumped because of this. 387 38820160622: 389 The libc stub for the pipe(2) system call has been replaced with 390 a wrapper that calls the pipe2(2) system call and the pipe(2) 391 system call is now only implemented by the kernels that include 392 "options COMPAT_FREEBSD10" in their config file (this is the 393 default). Users should ensure that this option is enabled in 394 their kernel or upgrade userspace to r302092 before upgrading their 395 kernel. 396 39720160527: 398 CAM will now strip leading spaces from SCSI disks' serial numbers. 399 This will affect users who create UFS filesystems on SCSI disks using 400 those disk's diskid device nodes. For example, if /etc/fstab 401 previously contained a line like 402 "/dev/diskid/DISK-%20%20%20%20%20%20%20ABCDEFG0123456", you should 403 change it to "/dev/diskid/DISK-ABCDEFG0123456". Users of geom 404 transforms like gmirror may also be affected. ZFS users should 405 generally be fine. 406 40720160523: 408 The bitstring(3) API has been updated with new functionality and 409 improved performance. But it is binary-incompatible with the old API. 410 Objects built with the new headers may not be linked against objects 411 built with the old headers. 412 41320160520: 414 The brk and sbrk functions have been removed from libc on arm64. 415 Binutils from ports has been updated to not link to these 416 functions and should be updated to the latest version before 417 installing a new libc. 418 41920160517: 420 The armv6 port now defaults to hard float ABI. Limited support 421 for running both hardfloat and soft float on the same system 422 is available using the libraries installed with -DWITH_LIBSOFT. 423 This has only been tested as an upgrade path for installworld 424 and packages may fail or need manual intervention to run. New 425 packages will be needed. 426 427 To update an existing self-hosted armv6hf system, you must add 428 TARGET_ARCH=armv6 on the make command line for both the build 429 and the install steps. 430 43120160510: 432 Kernel modules compiled outside of a kernel build now default to 433 installing to /boot/modules instead of /boot/kernel. Many kernel 434 modules built this way (such as those in ports) already overrode 435 KMODDIR explicitly to install into /boot/modules. However, 436 manually building and installing a module from /sys/modules will 437 now install to /boot/modules instead of /boot/kernel. 438 43920160414: 440 The CAM I/O scheduler has been committed to the kernel. There should be 441 no user visible impact. This does enable NCQ Trim on ada SSDs. While the 442 list of known rogues that claim support for this but actually corrupt 443 data is believed to be complete, be on the lookout for data 444 corruption. The known rogue list is believed to be complete: 445 446 o Crucial MX100, M550 drives with MU01 firmware. 447 o Micron M510 and M550 drives with MU01 firmware. 448 o Micron M500 prior to MU07 firmware 449 o Samsung 830, 840, and 850 all firmwares 450 o FCCT M500 all firmwares 451 452 Crucial has firmware http://www.crucial.com/usa/en/support-ssd-firmware 453 with working NCQ TRIM. For Micron branded drives, see your sales rep for 454 updated firmware. Black listed drives will work correctly because these 455 drives work correctly so long as no NCQ TRIMs are sent to them. Given 456 this list is the same as found in Linux, it's believed there are no 457 other rogues in the market place. All other models from the above 458 vendors work. 459 460 To be safe, if you are at all concerned, you can quirk each of your 461 drives to prevent NCQ from being sent by setting: 462 kern.cam.ada.X.quirks="0x2" 463 in loader.conf. If the drive requires the 4k sector quirk, set the 464 quirks entry to 0x3. 465 46620160330: 467 The FAST_DEPEND build option has been removed and its functionality is 468 now the one true way. The old mkdep(1) style of 'make depend' has 469 been removed. See 20160311 for further details. 470 47120160317: 472 Resource range types have grown from unsigned long to uintmax_t. All 473 drivers, and anything using libdevinfo, need to be recompiled. 474 47520160311: 476 WITH_FAST_DEPEND is now enabled by default for in-tree and out-of-tree 477 builds. It no longer runs mkdep(1) during 'make depend', and the 478 'make depend' stage can safely be skipped now as it is auto ran 479 when building 'make all' and will generate all SRCS and DPSRCS before 480 building anything else. Dependencies are gathered at compile time with 481 -MF flags kept in separate .depend files per object file. Users should 482 run 'make cleandepend' once if using -DNO_CLEAN to clean out older 483 stale .depend files. 484 48520160306: 486 On amd64, clang 3.8.0 can now insert sections of type AMD64_UNWIND into 487 kernel modules. Therefore, if you load any kernel modules at boot time, 488 please install the boot loaders after you install the kernel, but before 489 rebooting, e.g.: 490 491 make buildworld 492 make kernel KERNCONF=YOUR_KERNEL_HERE 493 make -C sys/boot install 494 <reboot in single user> 495 496 Then follow the usual steps, described in the General Notes section, 497 below. 498 49920160305: 500 Clang, llvm, lldb and compiler-rt have been upgraded to 3.8.0. Please 501 see the 20141231 entry below for information about prerequisites and 502 upgrading, if you are not already using clang 3.5.0 or higher. 503 50420160301: 505 The AIO subsystem is now a standard part of the kernel. The 506 VFS_AIO kernel option and aio.ko kernel module have been removed. 507 Due to stability concerns, asynchronous I/O requests are only 508 permitted on sockets and raw disks by default. To enable 509 asynchronous I/O requests on all file types, set the 510 vfs.aio.enable_unsafe sysctl to a non-zero value. 511 51220160226: 513 The ELF object manipulation tool objcopy is now provided by the 514 ELF Tool Chain project rather than by GNU binutils. It should be a 515 drop-in replacement, with the addition of arm64 support. The 516 (temporary) src.conf knob WITHOUT_ELFCOPY_AS_OBJCOPY knob may be set 517 to obtain the GNU version if necessary. 518 51920160129: 520 Building ZFS pools on top of zvols is prohibited by default. That 521 feature has never worked safely; it's always been prone to deadlocks. 522 Using a zvol as the backing store for a VM guest's virtual disk will 523 still work, even if the guest is using ZFS. Legacy behavior can be 524 restored by setting vfs.zfs.vol.recursive=1. 525 52620160119: 527 The NONE and HPN patches has been removed from OpenSSH. They are 528 still available in the security/openssh-portable port. 529 53020160113: 531 With the addition of ypldap(8), a new _ypldap user is now required 532 during installworld. "mergemaster -p" can be used to add the user 533 prior to installworld, as documented in the handbook. 534 53520151216: 536 The tftp loader (pxeboot) now uses the option root-path directive. As a 537 consequence it no longer looks for a pxeboot.4th file on the tftp 538 server. Instead it uses the regular /boot infrastructure as with the 539 other loaders. 540 54120151211: 542 The code to start recording plug and play data into the modules has 543 been committed. While the old tools will properly build a new kernel, 544 a number of warnings about "unknown metadata record 4" will be produced 545 for an older kldxref. To avoid such warnings, make sure to rebuild 546 the kernel toolchain (or world). Make sure that you have r292078 or 547 later when trying to build 292077 or later before rebuilding. 548 54920151207: 550 Debug data files are now built by default with 'make buildworld' and 551 installed with 'make installworld'. This facilitates debugging but 552 requires more disk space both during the build and for the installed 553 world. Debug files may be disabled by setting WITHOUT_DEBUG_FILES=yes 554 in src.conf(5). 555 55620151130: 557 r291527 changed the internal interface between the nfsd.ko and 558 nfscommon.ko modules. As such, they must both be upgraded to-gether. 559 __FreeBSD_version has been bumped because of this. 560 56120151108: 562 Add support for unicode collation strings leads to a change of 563 order of files listed by ls(1) for example. To get back to the old 564 behaviour, set LC_COLLATE environment variable to "C". 565 566 Databases administrators will need to reindex their databases given 567 collation results will be different. 568 569 Due to a bug in install(1) it is recommended to remove the ancient 570 locales before running make installworld. 571 572 rm -rf /usr/share/locale/* 573 57420151030: 575 The OpenSSL has been upgraded to 1.0.2d. Any binaries requiring 576 libcrypto.so.7 or libssl.so.7 must be recompiled. 577 57820151020: 579 Qlogic 24xx/25xx firmware images were updated from 5.5.0 to 7.3.0. 580 Kernel modules isp_2400_multi and isp_2500_multi were removed and 581 should be replaced with isp_2400 and isp_2500 modules respectively. 582 58320151017: 584 The build previously allowed using 'make -n' to not recurse into 585 sub-directories while showing what commands would be executed, and 586 'make -n -n' to recursively show commands. Now 'make -n' will recurse 587 and 'make -N' will not. 588 58920151012: 590 If you specify SENDMAIL_MC or SENDMAIL_CF in make.conf, mergemaster 591 and etcupdate will now use this file. A custom sendmail.cf is now 592 updated via this mechanism rather than via installworld. If you had 593 excluded sendmail.cf in mergemaster.rc or etcupdate.conf, you may 594 want to remove the exclusion or change it to "always install". 595 /etc/mail/sendmail.cf is now managed the same way regardless of 596 whether SENDMAIL_MC/SENDMAIL_CF is used. If you are not using 597 SENDMAIL_MC/SENDMAIL_CF there should be no change in behavior. 598 59920151011: 600 Compatibility shims for legacy ATA device names have been removed. 601 It includes ATA_STATIC_ID kernel option, kern.cam.ada.legacy_aliases 602 and kern.geom.raid.legacy_aliases loader tunables, kern.devalias.* 603 environment variables, /dev/ad* and /dev/ar* symbolic links. 604 60520151006: 606 Clang, llvm, lldb, compiler-rt and libc++ have been upgraded to 3.7.0. 607 Please see the 20141231 entry below for information about prerequisites 608 and upgrading, if you are not already using clang 3.5.0 or higher. 609 61020150924: 611 Kernel debug files have been moved to /usr/lib/debug/boot/kernel/, 612 and renamed from .symbols to .debug. This reduces the size requirements 613 on the boot partition or file system and provides consistency with 614 userland debug files. 615 616 When using the supported kernel installation method the 617 /usr/lib/debug/boot/kernel directory will be renamed (to kernel.old) 618 as is done with /boot/kernel. 619 620 Developers wishing to maintain the historical behavior of installing 621 debug files in /boot/kernel/ can set KERN_DEBUGDIR="" in src.conf(5). 622 62320150827: 624 The wireless drivers had undergone changes that remove the 'parent 625 interface' from the ifconfig -l output. The rc.d network scripts 626 used to check presence of a parent interface in the list, so old 627 scripts would fail to start wireless networking. Thus, etcupdate(3) 628 or mergemaster(8) run is required after kernel update, to update your 629 rc.d scripts in /etc. 630 63120150827: 632 pf no longer supports 'scrub fragment crop' or 'scrub fragment drop-ovl' 633 These configurations are now automatically interpreted as 634 'scrub fragment reassemble'. 635 63620150817: 637 Kernel-loadable modules for the random(4) device are back. To use 638 them, the kernel must have 639 640 device random 641 options RANDOM_LOADABLE 642 643 kldload(8) can then be used to load random_fortuna.ko 644 or random_yarrow.ko. Please note that due to the indirect 645 function calls that the loadable modules need to provide, 646 the build-in variants will be slightly more efficient. 647 648 The random(4) kernel option RANDOM_DUMMY has been retired due to 649 unpopularity. It was not all that useful anyway. 650 65120150813: 652 The WITHOUT_ELFTOOLCHAIN_TOOLS src.conf(5) knob has been retired. 653 Control over building the ELF Tool Chain tools is now provided by 654 the WITHOUT_TOOLCHAIN knob. 655 65620150810: 657 The polarity of Pulse Per Second (PPS) capture events with the 658 uart(4) driver has been corrected. Prior to this change the PPS 659 "assert" event corresponded to the trailing edge of a positive PPS 660 pulse and the "clear" event was the leading edge of the next pulse. 661 662 As the width of a PPS pulse in a typical GPS receiver is on the 663 order of 1 millisecond, most users will not notice any significant 664 difference with this change. 665 666 Anyone who has compensated for the historical polarity reversal by 667 configuring a negative offset equal to the pulse width will need to 668 remove that workaround. 669 67020150809: 671 The default group assigned to /dev/dri entries has been changed 672 from 'wheel' to 'video' with the id of '44'. If you want to have 673 access to the dri devices please add yourself to the video group 674 with: 675 676 # pw groupmod video -m $USER 677 67820150806: 679 The menu.rc and loader.rc files will now be replaced during 680 upgrades. Please migrate local changes to menu.rc.local and 681 loader.rc.local instead. 682 68320150805: 684 GNU Binutils versions of addr2line, c++filt, nm, readelf, size, 685 strings and strip have been removed. The src.conf(5) knob 686 WITHOUT_ELFTOOLCHAIN_TOOLS no longer provides the binutils tools. 687 68820150728: 689 As ZFS requires more kernel stack pages than is the default on some 690 architectures e.g. i386, it now warns if KSTACK_PAGES is less than 691 ZFS_MIN_KSTACK_PAGES (which is 4 at the time of writing). 692 693 Please consider using 'options KSTACK_PAGES=X' where X is greater 694 than or equal to ZFS_MIN_KSTACK_PAGES i.e. 4 in such configurations. 695 69620150706: 697 sendmail has been updated to 8.15.2. Starting with FreeBSD 11.0 698 and sendmail 8.15, sendmail uses uncompressed IPv6 addresses by 699 default, i.e., they will not contain "::". For example, instead 700 of ::1, it will be 0:0:0:0:0:0:0:1. This permits a zero subnet 701 to have a more specific match, such as different map entries for 702 IPv6:0:0 vs IPv6:0. This change requires that configuration 703 data (including maps, files, classes, custom ruleset, etc.) must 704 use the same format, so make certain such configuration data is 705 upgrading. As a very simple check search for patterns like 706 'IPv6:[0-9a-fA-F:]*::' and 'IPv6::'. To return to the old 707 behavior, set the m4 option confUSE_COMPRESSED_IPV6_ADDRESSES or 708 the cf option UseCompressedIPv6Addresses. 709 71020150630: 711 The default kernel entropy-processing algorithm is now 712 Fortuna, replacing Yarrow. 713 714 Assuming you have 'device random' in your kernel config 715 file, the configurations allow a kernel option to override 716 this default. You may choose *ONE* of: 717 718 options RANDOM_YARROW # Legacy /dev/random algorithm. 719 options RANDOM_DUMMY # Blocking-only driver. 720 721 If you have neither, you get Fortuna. For most people, 722 read no further, Fortuna will give a /dev/random that works 723 like it always used to, and the difference will be irrelevant. 724 725 If you remove 'device random', you get *NO* kernel-processed 726 entropy at all. This may be acceptable to folks building 727 embedded systems, but has complications. Carry on reading, 728 and it is assumed you know what you need. 729 730 *PLEASE* read random(4) and random(9) if you are in the 731 habit of tweaking kernel configs, and/or if you are a member 732 of the embedded community, wanting specific and not-usual 733 behaviour from your security subsystems. 734 735 NOTE!! If you use RANDOM_DUMMY and/or have no 'device 736 random', you will NOT have a functioning /dev/random, and 737 many cryptographic features will not work, including SSH. 738 You may also find strange behaviour from the random(3) set 739 of library functions, in particular sranddev(3), srandomdev(3) 740 and arc4random(3). The reason for this is that the KERN_ARND 741 sysctl only returns entropy if it thinks it has some to 742 share, and with RANDOM_DUMMY or no 'device random' this 743 will never happen. 744 74520150623: 746 An additional fix for the issue described in the 20150614 sendmail 747 entry below has been been committed in revision 284717. 748 74920150616: 750 FreeBSD's old make (fmake) has been removed from the system. It is 751 available as the devel/fmake port or via pkg install fmake. 752 75320150615: 754 The fix for the issue described in the 20150614 sendmail entry 755 below has been been committed in revision 284436. The work 756 around described in that entry is no longer needed unless the 757 default setting is overridden by a confDH_PARAMETERS configuration 758 setting of '5' or pointing to a 512 bit DH parameter file. 759 76020150614: 761 ALLOW_DEPRECATED_ATF_TOOLS/ATFFILE support has been removed from 762 atf.test.mk (included from bsd.test.mk). Please upgrade devel/atf 763 and devel/kyua to version 0.20+ and adjust any calling code to work 764 with Kyuafile and kyua. 765 76620150614: 767 The import of openssl to address the FreeBSD-SA-15:10.openssl 768 security advisory includes a change which rejects handshakes 769 with DH parameters below 768 bits. sendmail releases prior 770 to 8.15.2 (not yet released), defaulted to a 512 bit 771 DH parameter setting for client connections. To work around 772 this interoperability, sendmail can be configured to use a 773 2048 bit DH parameter by: 774 775 1. Edit /etc/mail/`hostname`.mc 776 2. If a setting for confDH_PARAMETERS does not exist or 777 exists and is set to a string beginning with '5', 778 replace it with '2'. 779 3. If a setting for confDH_PARAMETERS exists and is set to 780 a file path, create a new file with: 781 openssl dhparam -out /path/to/file 2048 782 4. Rebuild the .cf file: 783 cd /etc/mail/; make; make install 784 5. Restart sendmail: 785 cd /etc/mail/; make restart 786 787 A sendmail patch is coming, at which time this file will be 788 updated. 789 79020150604: 791 Generation of legacy formatted entries have been disabled by default 792 in pwd_mkdb(8), as all base system consumers of the legacy formatted 793 entries were converted to use the new format by default when the new, 794 machine independent format have been added and supported since FreeBSD 795 5.x. 796 797 Please see the pwd_mkdb(8) manual page for further details. 798 79920150525: 800 Clang and llvm have been upgraded to 3.6.1 release. Please see the 801 20141231 entry below for information about prerequisites and upgrading, 802 if you are not already using 3.5.0 or higher. 803 80420150521: 805 TI platform code switched to using vendor DTS files and this update 806 may break existing systems running on Beaglebone, Beaglebone Black, 807 and Pandaboard: 808 809 - dtb files should be regenerated/reinstalled. Filenames are the 810 same but content is different now 811 - GPIO addressing was changed, now each GPIO bank (32 pins per bank) 812 has its own /dev/gpiocX device, e.g. pin 121 on /dev/gpioc0 in old 813 addressing scheme is now pin 25 on /dev/gpioc3. 814 - Pandaboard: /etc/ttys should be updated, serial console device is 815 now /dev/ttyu2, not /dev/ttyu0 816 81720150501: 818 soelim(1) from gnu/usr.bin/groff has been replaced by usr.bin/soelim. 819 If you need the GNU extension from groff soelim(1), install groff 820 from package: pkg install groff, or via ports: textproc/groff. 821 82220150423: 823 chmod, chflags, chown and chgrp now affect symlinks in -R mode as 824 defined in symlink(7); previously symlinks were silently ignored. 825 82620150415: 827 The const qualifier has been removed from iconv(3) to comply with 828 POSIX. The ports tree is aware of this from r384038 onwards. 829 83020150416: 831 Libraries specified by LIBADD in Makefiles must have a corresponding 832 DPADD_<lib> variable to ensure correct dependencies. This is now 833 enforced in src.libnames.mk. 834 83520150324: 836 From legacy ata(4) driver was removed support for SATA controllers 837 supported by more functional drivers ahci(4), siis(4) and mvs(4). 838 Kernel modules ataahci and ataadaptec were removed completely, 839 replaced by ahci and mvs modules respectively. 840 84120150315: 842 Clang, llvm and lldb have been upgraded to 3.6.0 release. Please see 843 the 20141231 entry below for information about prerequisites and 844 upgrading, if you are not already using 3.5.0 or higher. 845 84620150307: 847 The 32-bit PowerPC kernel has been changed to a position-independent 848 executable. This can only be booted with a version of loader(8) 849 newer than January 31, 2015, so make sure to update both world and 850 kernel before rebooting. 851 85220150217: 853 If you are running a -CURRENT kernel since r273872 (Oct 30th, 2014), 854 but before r278950, the RNG was not seeded properly. Immediately 855 upgrade the kernel to r278950 or later and regenerate any keys (e.g. 856 ssh keys or openssl keys) that were generated w/ a kernel from that 857 range. This does not affect programs that directly used /dev/random 858 or /dev/urandom. All userland uses of arc4random(3) are affected. 859 86020150210: 861 The autofs(4) ABI was changed in order to restore binary compatibility 862 with 10.1-RELEASE. The automountd(8) daemon needs to be rebuilt to work 863 with the new kernel. 864 86520150131: 866 The powerpc64 kernel has been changed to a position-independent 867 executable. This can only be booted with a new version of loader(8), 868 so make sure to update both world and kernel before rebooting. 869 87020150118: 871 Clang and llvm have been upgraded to 3.5.1 release. This is a bugfix 872 only release, no new features have been added. Please see the 20141231 873 entry below for information about prerequisites and upgrading, if you 874 are not already using 3.5.0. 875 87620150107: 877 ELF tools addr2line, elfcopy (strip), nm, size, and strings are now 878 taken from the ELF Tool Chain project rather than GNU binutils. They 879 should be drop-in replacements, with the addition of arm64 support. 880 The WITHOUT_ELFTOOLCHAIN_TOOLS= knob may be used to obtain the 881 binutils tools, if necessary. See 20150805 for updated information. 882 88320150105: 884 The default Unbound configuration now enables remote control 885 using a local socket. Users who have already enabled the 886 local_unbound service should regenerate their configuration 887 by running "service local_unbound setup" as root. 888 88920150102: 890 The GNU texinfo and GNU info pages have been removed. 891 To be able to view GNU info pages please install texinfo from ports. 892 89320141231: 894 Clang, llvm and lldb have been upgraded to 3.5.0 release. 895 896 As of this release, a prerequisite for building clang, llvm and lldb is 897 a C++11 capable compiler and C++11 standard library. This means that to 898 be able to successfully build the cross-tools stage of buildworld, with 899 clang as the bootstrap compiler, your system compiler or cross compiler 900 should either be clang 3.3 or later, or gcc 4.8 or later, and your 901 system C++ library should be libc++, or libdstdc++ from gcc 4.8 or 902 later. 903 904 On any standard FreeBSD 10.x or 11.x installation, where clang and 905 libc++ are on by default (that is, on x86 or arm), this should work out 906 of the box. 907 908 On 9.x installations where clang is enabled by default, e.g. on x86 and 909 powerpc, libc++ will not be enabled by default, so libc++ should be 910 built (with clang) and installed first. If both clang and libc++ are 911 missing, build clang first, then use it to build libc++. 912 913 On 8.x and earlier installations, upgrade to 9.x first, and then follow 914 the instructions for 9.x above. 915 916 Sparc64 and mips users are unaffected, as they still use gcc 4.2.1 by 917 default, and do not build clang. 918 919 Many embedded systems are resource constrained, and will not be able to 920 build clang in a reasonable time, or in some cases at all. In those 921 cases, cross building bootable systems on amd64 is a workaround. 922 923 This new version of clang introduces a number of new warnings, of which 924 the following are most likely to appear: 925 926 -Wabsolute-value 927 928 This warns in two cases, for both C and C++: 929 * When the code is trying to take the absolute value of an unsigned 930 quantity, which is effectively a no-op, and almost never what was 931 intended. The code should be fixed, if at all possible. If you are 932 sure that the unsigned quantity can be safely cast to signed, without 933 loss of information or undefined behavior, you can add an explicit 934 cast, or disable the warning. 935 936 * When the code is trying to take an absolute value, but the called 937 abs() variant is for the wrong type, which can lead to truncation. 938 If you want to disable the warning instead of fixing the code, please 939 make sure that truncation will not occur, or it might lead to unwanted 940 side-effects. 941 942 -Wtautological-undefined-compare and 943 -Wundefined-bool-conversion 944 945 These warn when C++ code is trying to compare 'this' against NULL, while 946 'this' should never be NULL in well-defined C++ code. However, there is 947 some legacy (pre C++11) code out there, which actively abuses this 948 feature, which was less strictly defined in previous C++ versions. 949 950 Squid and openjdk do this, for example. The warning can be turned off 951 for C++98 and earlier, but compiling the code in C++11 mode might result 952 in unexpected behavior; for example, the parts of the program that are 953 unreachable could be optimized away. 954 95520141222: 956 The old NFS client and server (kernel options NFSCLIENT, NFSSERVER) 957 kernel sources have been removed. The .h files remain, since some 958 utilities include them. This will need to be fixed later. 959 If "mount -t oldnfs ..." is attempted, it will fail. 960 If the "-o" option on mountd(8), nfsd(8) or nfsstat(1) is used, 961 the utilities will report errors. 962 96320141121: 964 The handling of LOCAL_LIB_DIRS has been altered to skip addition of 965 directories to top level SUBDIR variable when their parent 966 directory is included in LOCAL_DIRS. Users with build systems with 967 such hierarchies and without SUBDIR entries in the parent 968 directory Makefiles should add them or add the directories to 969 LOCAL_DIRS. 970 97120141109: 972 faith(4) and faithd(8) have been removed from the base system. Faith 973 has been obsolete for a very long time. 974 97520141104: 976 vt(4), the new console driver, is enabled by default. It brings 977 support for Unicode and double-width characters, as well as 978 support for UEFI and integration with the KMS kernel video 979 drivers. 980 981 You may need to update your console settings in /etc/rc.conf, 982 most probably the keymap. During boot, /etc/rc.d/syscons will 983 indicate what you need to do. 984 985 vt(4) still has issues and lacks some features compared to 986 syscons(4). See the wiki for up-to-date information: 987 https://wiki.freebsd.org/Newcons 988 989 If you want to keep using syscons(4), you can do so by adding 990 the following line to /boot/loader.conf: 991 kern.vty=sc 992 99320141102: 994 pjdfstest has been integrated into kyua as an opt-in test suite. 995 Please see share/doc/pjdfstest/README for more details on how to 996 execute it. 997 99820141009: 999 gperf has been removed from the base system for architectures 1000 that use clang. Ports that require gperf will obtain it from the 1001 devel/gperf port. 1002 100320140923: 1004 pjdfstest has been moved from tools/regression/pjdfstest to 1005 contrib/pjdfstest . 1006 100720140922: 1008 At svn r271982, The default linux compat kernel ABI has been adjusted 1009 to 2.6.18 in support of the linux-c6 compat ports infrastructure 1010 update. If you wish to continue using the linux-f10 compat ports, 1011 add compat.linux.osrelease=2.6.16 to your local sysctl.conf. Users are 1012 encouraged to update their linux-compat packages to linux-c6 during 1013 their next update cycle. 1014 101520140729: 1016 The ofwfb driver, used to provide a graphics console on PowerPC when 1017 using vt(4), no longer allows mmap() of all physical memory. This 1018 will prevent Xorg on PowerPC with some ATI graphics cards from 1019 initializing properly unless x11-servers/xorg-server is updated to 1020 1.12.4_8 or newer. 1021 102220140723: 1023 The xdev targets have been converted to using TARGET and 1024 TARGET_ARCH instead of XDEV and XDEV_ARCH. 1025 102620140719: 1027 The default unbound configuration has been modified to address 1028 issues with reverse lookups on networks that use private 1029 address ranges. If you use the local_unbound service, run 1030 "service local_unbound setup" as root to regenerate your 1031 configuration, then "service local_unbound reload" to load the 1032 new configuration. 1033 103420140709: 1035 The GNU texinfo and GNU info pages are not built and installed 1036 anymore, WITH_INFO knob has been added to allow to built and install 1037 them again. 1038 UPDATE: see 20150102 entry on texinfo's removal 1039 104020140708: 1041 The GNU readline library is now an INTERNALLIB - that is, it is 1042 statically linked into consumers (GDB and variants) in the base 1043 system, and the shared library is no longer installed. The 1044 devel/readline port is available for third party software that 1045 requires readline. 1046 104720140702: 1048 The Itanium architecture (ia64) has been removed from the list of 1049 known architectures. This is the first step in the removal of the 1050 architecture. 1051 105220140701: 1053 Commit r268115 has added NFSv4.1 server support, merged from 1054 projects/nfsv4.1-server. Since this includes changes to the 1055 internal interfaces between the NFS related modules, a full 1056 build of the kernel and modules will be necessary. 1057 __FreeBSD_version has been bumped. 1058 105920140629: 1060 The WITHOUT_VT_SUPPORT kernel config knob has been renamed 1061 WITHOUT_VT. (The other _SUPPORT knobs have a consistent meaning 1062 which differs from the behaviour controlled by this knob.) 1063 106420140619: 1065 Maximal length of the serial number in CTL was increased from 16 to 1066 64 chars, that breaks ABI. All CTL-related tools, such as ctladm 1067 and ctld, need to be rebuilt to work with a new kernel. 1068 106920140606: 1070 The libatf-c and libatf-c++ major versions were downgraded to 0 and 1071 1 respectively to match the upstream numbers. They were out of 1072 sync because, when they were originally added to FreeBSD, the 1073 upstream versions were not respected. These libraries are private 1074 and not yet built by default, so renumbering them should be a 1075 non-issue. However, unclean source trees will yield broken test 1076 programs once the operator executes "make delete-old-libs" after a 1077 "make installworld". 1078 1079 Additionally, the atf-sh binary was made private by moving it into 1080 /usr/libexec/. Already-built shell test programs will keep the 1081 path to the old binary so they will break after "make delete-old" 1082 is run. 1083 1084 If you are using WITH_TESTS=yes (not the default), wipe the object 1085 tree and rebuild from scratch to prevent spurious test failures. 1086 This is only needed once: the misnumbered libraries and misplaced 1087 binaries have been added to OptionalObsoleteFiles.inc so they will 1088 be removed during a clean upgrade. 1089 109020140512: 1091 Clang and llvm have been upgraded to 3.4.1 release. 1092 109320140508: 1094 We bogusly installed src.opts.mk in /usr/share/mk. This file should 1095 be removed to avoid issues in the future (and has been added to 1096 ObsoleteFiles.inc). 1097 109820140505: 1099 /etc/src.conf now affects only builds of the FreeBSD src tree. In the 1100 past, it affected all builds that used the bsd.*.mk files. The old 1101 behavior was a bug, but people may have relied upon it. To get this 1102 behavior back, you can .include /etc/src.conf from /etc/make.conf 1103 (which is still global and isn't changed). This also changes the 1104 behavior of incremental builds inside the tree of individual 1105 directories. Set MAKESYSPATH to ".../share/mk" to do that. 1106 Although this has survived make universe and some upgrade scenarios, 1107 other upgrade scenarios may have broken. At least one form of 1108 temporary breakage was fixed with MAKESYSPATH settings for buildworld 1109 as well... In cases where MAKESYSPATH isn't working with this 1110 setting, you'll need to set it to the full path to your tree. 1111 1112 One side effect of all this cleaning up is that bsd.compiler.mk 1113 is no longer implicitly included by bsd.own.mk. If you wish to 1114 use COMPILER_TYPE, you must now explicitly include bsd.compiler.mk 1115 as well. 1116 111720140430: 1118 The lindev device has been removed since /dev/full has been made a 1119 standard device. __FreeBSD_version has been bumped. 1120 112120140424: 1122 The knob WITHOUT_VI was added to the base system, which controls 1123 building ex(1), vi(1), etc. Older releases of FreeBSD required ex(1) 1124 in order to reorder files share/termcap and didn't build ex(1) as a 1125 build tool, so building/installing with WITH_VI is highly advised for 1126 build hosts for older releases. 1127 1128 This issue has been fixed in stable/9 and stable/10 in r277022 and 1129 r276991, respectively. 1130 113120140418: 1132 The YES_HESIOD knob has been removed. It has been obsolete for 1133 a decade. Please move to using WITH_HESIOD instead or your builds 1134 will silently lack HESIOD. 1135 113620140405: 1137 The uart(4) driver has been changed with respect to its handling 1138 of the low-level console. Previously the uart(4) driver prevented 1139 any process from changing the baudrate or the CLOCAL and HUPCL 1140 control flags. By removing the restrictions, operators can make 1141 changes to the serial console port without having to reboot. 1142 However, when getty(8) is started on the serial device that is 1143 associated with the low-level console, a misconfigured terminal 1144 line in /etc/ttys will now have a real impact. 1145 Before upgrading the kernel, make sure that /etc/ttys has the 1146 serial console device configured as 3wire without baudrate to 1147 preserve the previous behaviour. E.g: 1148 ttyu0 "/usr/libexec/getty 3wire" vt100 on secure 1149 115020140306: 1151 Support for libwrap (TCP wrappers) in rpcbind was disabled by default 1152 to improve performance. To re-enable it, if needed, run rpcbind 1153 with command line option -W. 1154 115520140226: 1156 Switched back to the GPL dtc compiler due to updates in the upstream 1157 dts files not being supported by the BSDL dtc compiler. You will need 1158 to rebuild your kernel toolchain to pick up the new compiler. Core dumps 1159 may result while building dtb files during a kernel build if you fail 1160 to do so. Set WITHOUT_GPL_DTC if you require the BSDL compiler. 1161 116220140216: 1163 Clang and llvm have been upgraded to 3.4 release. 1164 116520140216: 1166 The nve(4) driver has been removed. Please use the nfe(4) driver 1167 for NVIDIA nForce MCP Ethernet adapters instead. 1168 116920140212: 1170 An ABI incompatibility crept into the libc++ 3.4 import in r261283. 1171 This could cause certain C++ applications using shared libraries built 1172 against the previous version of libc++ to crash. The incompatibility 1173 has now been fixed, but any C++ applications or shared libraries built 1174 between r261283 and r261801 should be recompiled. 1175 117620140204: 1177 OpenSSH will now ignore errors caused by kernel lacking of Capsicum 1178 capability mode support. Please note that enabling the feature in 1179 kernel is still highly recommended. 1180 118120140131: 1182 OpenSSH is now built with sandbox support, and will use sandbox as 1183 the default privilege separation method. This requires Capsicum 1184 capability mode support in kernel. 1185 118620140128: 1187 The libelf and libdwarf libraries have been updated to newer 1188 versions from upstream. Shared library version numbers for 1189 these two libraries were bumped. Any ports or binaries 1190 requiring these two libraries should be recompiled. 1191 __FreeBSD_version is bumped to 1100006. 1192 119320140110: 1194 If a Makefile in a tests/ directory was auto-generating a Kyuafile 1195 instead of providing an explicit one, this would prevent such 1196 Makefile from providing its own Kyuafile in the future during 1197 NO_CLEAN builds. This has been fixed in the Makefiles but manual 1198 intervention is needed to clean an objdir if you use NO_CLEAN: 1199 # find /usr/obj -name Kyuafile | xargs rm -f 1200 120120131213: 1202 The behavior of gss_pseudo_random() for the krb5 mechanism 1203 has changed, for applications requesting a longer random string 1204 than produced by the underlying enctype's pseudo-random() function. 1205 In particular, the random string produced from a session key of 1206 enctype aes256-cts-hmac-sha1-96 or aes256-cts-hmac-sha1-96 will 1207 be different at the 17th octet and later, after this change. 1208 The counter used in the PRF+ construction is now encoded as a 1209 big-endian integer in accordance with RFC 4402. 1210 __FreeBSD_version is bumped to 1100004. 1211 121220131108: 1213 The WITHOUT_ATF build knob has been removed and its functionality 1214 has been subsumed into the more generic WITHOUT_TESTS. If you were 1215 using the former to disable the build of the ATF libraries, you 1216 should change your settings to use the latter. 1217 121820131025: 1219 The default version of mtree is nmtree which is obtained from 1220 NetBSD. The output is generally the same, but may vary 1221 slightly. If you found you need identical output adding 1222 "-F freebsd9" to the command line should do the trick. For the 1223 time being, the old mtree is available as fmtree. 1224 122520131014: 1226 libbsdyml has been renamed to libyaml and moved to /usr/lib/private. 1227 This will break ports-mgmt/pkg. Rebuild the port, or upgrade to pkg 1228 1.1.4_8 and verify bsdyml not linked in, before running "make 1229 delete-old-libs": 1230 # make -C /usr/ports/ports-mgmt/pkg build deinstall install clean 1231 or 1232 # pkg install pkg; ldd /usr/local/sbin/pkg | grep bsdyml 1233 123420131010: 1235 The stable/10 branch has been created in subversion from head 1236 revision r256279. 1237 123820131010: 1239 The rc.d/jail script has been updated to support jail(8) 1240 configuration file. The "jail_<jname>_*" rc.conf(5) variables 1241 for per-jail configuration are automatically converted to 1242 /var/run/jail.<jname>.conf before the jail(8) utility is invoked. 1243 This is transparently backward compatible. See below about some 1244 incompatibilities and rc.conf(5) manual page for more details. 1245 1246 These variables are now deprecated in favor of jail(8) configuration 1247 file. One can use "rc.d/jail config <jname>" command to generate 1248 a jail(8) configuration file in /var/run/jail.<jname>.conf without 1249 running the jail(8) utility. The default pathname of the 1250 configuration file is /etc/jail.conf and can be specified by 1251 using $jail_conf or $jail_<jname>_conf variables. 1252 1253 Please note that jail_devfs_ruleset accepts an integer at 1254 this moment. Please consider to rewrite the ruleset name 1255 with an integer. 1256 125720130930: 1258 BIND has been removed from the base system. If all you need 1259 is a local resolver, simply enable and start the local_unbound 1260 service instead. Otherwise, several versions of BIND are 1261 available in the ports tree. The dns/bind99 port is one example. 1262 1263 With this change, nslookup(1) and dig(1) are no longer in the base 1264 system. Users should instead use host(1) and drill(1) which are 1265 in the base system. Alternatively, nslookup and dig can 1266 be obtained by installing the dns/bind-tools port. 1267 126820130916: 1269 With the addition of unbound(8), a new unbound user is now 1270 required during installworld. "mergemaster -p" can be used to 1271 add the user prior to installworld, as documented in the handbook. 1272 127320130911: 1274 OpenSSH is now built with DNSSEC support, and will by default 1275 silently trust signed SSHFP records. This can be controlled with 1276 the VerifyHostKeyDNS client configuration setting. DNSSEC support 1277 can be disabled entirely with the WITHOUT_LDNS option in src.conf. 1278 127920130906: 1280 The GNU Compiler Collection and C++ standard library (libstdc++) 1281 are no longer built by default on platforms where clang is the system 1282 compiler. You can enable them with the WITH_GCC and WITH_GNUCXX 1283 options in src.conf. 1284 128520130905: 1286 The PROCDESC kernel option is now part of the GENERIC kernel 1287 configuration and is required for the rwhod(8) to work. 1288 If you are using custom kernel configuration, you should include 1289 'options PROCDESC'. 1290 129120130905: 1292 The API and ABI related to the Capsicum framework was modified 1293 in backward incompatible way. The userland libraries and programs 1294 have to be recompiled to work with the new kernel. This includes the 1295 following libraries and programs, but the whole buildworld is 1296 advised: libc, libprocstat, dhclient, tcpdump, hastd, hastctl, 1297 kdump, procstat, rwho, rwhod, uniq. 1298 129920130903: 1300 AES-NI intrinsic support has been added to gcc. The AES-NI module 1301 has been updated to use this support. A new gcc is required to build 1302 the aesni module on both i386 and amd64. 1303 130420130821: 1305 The PADLOCK_RNG and RDRAND_RNG kernel options are now devices. 1306 Thus "device padlock_rng" and "device rdrand_rng" should be 1307 used instead of "options PADLOCK_RNG" & "options RDRAND_RNG". 1308 130920130813: 1310 WITH_ICONV has been split into two feature sets. WITH_ICONV now 1311 enables just the iconv* functionality and is now on by default. 1312 WITH_LIBICONV_COMPAT enables the libiconv api and link time 1313 compatibility. Set WITHOUT_ICONV to build the old way. 1314 If you have been using WITH_ICONV before, you will very likely 1315 need to turn on WITH_LIBICONV_COMPAT. 1316 131720130806: 1318 INVARIANTS option now enables DEBUG for code with OpenSolaris and 1319 Illumos origin, including ZFS. If you have INVARIANTS in your 1320 kernel configuration, then there is no need to set DEBUG or ZFS_DEBUG 1321 explicitly. 1322 DEBUG used to enable witness(9) tracking of OpenSolaris (mostly ZFS) 1323 locks if WITNESS option was set. Because that generated a lot of 1324 witness(9) reports and all of them were believed to be false 1325 positives, this is no longer done. New option OPENSOLARIS_WITNESS 1326 can be used to achieve the previous behavior. 1327 132820130806: 1329 Timer values in IPv6 data structures now use time_uptime instead 1330 of time_second. Although this is not a user-visible functional 1331 change, userland utilities which directly use them---ndp(8), 1332 rtadvd(8), and rtsold(8) in the base system---need to be updated 1333 to r253970 or later. 1334 133520130802: 1336 find -delete can now delete the pathnames given as arguments, 1337 instead of only files found below them or if the pathname did 1338 not contain any slashes. Formerly, the following error message 1339 would result: 1340 1341 find: -delete: <path>: relative path potentially not safe 1342 1343 Deleting the pathnames given as arguments can be prevented 1344 without error messages using -mindepth 1 or by changing 1345 directory and passing "." as argument to find. This works in the 1346 old as well as the new version of find. 1347 134820130726: 1349 Behavior of devfs rules path matching has been changed. 1350 Pattern is now always matched against fully qualified devfs 1351 path and slash characters must be explicitly matched by 1352 slashes in pattern (FNM_PATHNAME). Rulesets involving devfs 1353 subdirectories must be reviewed. 1354 135520130716: 1356 The default ARM ABI has changed to the ARM EABI. The old ABI is 1357 incompatible with the ARM EABI and all programs and modules will 1358 need to be rebuilt to work with a new kernel. 1359 1360 To keep using the old ABI ensure the WITHOUT_ARM_EABI knob is set. 1361 1362 NOTE: Support for the old ABI will be removed in the future and 1363 users are advised to upgrade. 1364 136520130709: 1366 pkg_install has been disconnected from the build if you really need it 1367 you should add WITH_PKGTOOLS in your src.conf(5). 1368 136920130709: 1370 Most of network statistics structures were changed to be able 1371 keep 64-bits counters. Thus all tools, that work with networking 1372 statistics, must be rebuilt (netstat(1), bsnmpd(1), etc.) 1373 137420130618: 1375 Fix a bug that allowed a tracing process (e.g. gdb) to write 1376 to a memory-mapped file in the traced process's address space 1377 even if neither the traced process nor the tracing process had 1378 write access to that file. 1379 138020130615: 1381 CVS has been removed from the base system. An exact copy 1382 of the code is available from the devel/cvs port. 1383 138420130613: 1385 Some people report the following error after the switch to bmake: 1386 1387 make: illegal option -- J 1388 usage: make [-BPSXeiknpqrstv] [-C directory] [-D variable] 1389 ... 1390 *** [buildworld] Error code 2 1391 1392 this likely due to an old instance of make in 1393 ${MAKEPATH} (${MAKEOBJDIRPREFIX}${.CURDIR}/make.${MACHINE}) 1394 which src/Makefile will use that blindly, if it exists, so if 1395 you see the above error: 1396 1397 rm -rf `make -V MAKEPATH` 1398 1399 should resolve it. 1400 140120130516: 1402 Use bmake by default. 1403 Whereas before one could choose to build with bmake via 1404 -DWITH_BMAKE one must now use -DWITHOUT_BMAKE to use the old 1405 make. The goal is to remove these knobs for 10-RELEASE. 1406 1407 It is worth noting that bmake (like gmake) treats the command 1408 line as the unit of failure, rather than statements within the 1409 command line. Thus '(cd some/where && dosomething)' is safer 1410 than 'cd some/where; dosomething'. The '()' allows consistent 1411 behavior in parallel build. 1412 141320130429: 1414 Fix a bug that allows NFS clients to issue READDIR on files. 1415 141620130426: 1417 The WITHOUT_IDEA option has been removed because 1418 the IDEA patent expired. 1419 142020130426: 1421 The sysctl which controls TRIM support under ZFS has been renamed 1422 from vfs.zfs.trim_disable -> vfs.zfs.trim.enabled and has been 1423 enabled by default. 1424 142520130425: 1426 The mergemaster command now uses the default MAKEOBJDIRPREFIX 1427 rather than creating it's own in the temporary directory in 1428 order allow access to bootstrapped versions of tools such as 1429 install and mtree. When upgrading from version of FreeBSD where 1430 the install command does not support -l, you will need to 1431 install a new mergemaster command if mergemaster -p is required. 1432 This can be accomplished with the command (cd src/usr.sbin/mergemaster 1433 && make install). 1434 143520130404: 1436 Legacy ATA stack, disabled and replaced by new CAM-based one since 1437 FreeBSD 9.0, completely removed from the sources. Kernel modules 1438 atadisk and atapi*, user-level tools atacontrol and burncd are 1439 removed. Kernel option `options ATA_CAM` is now permanently enabled 1440 and removed. 1441 144220130319: 1443 SOCK_CLOEXEC and SOCK_NONBLOCK flags have been added to socket(2) 1444 and socketpair(2). Software, in particular Kerberos, may 1445 automatically detect and use these during building. The resulting 1446 binaries will not work on older kernels. 1447 144820130308: 1449 CTL_DISABLE has also been added to the sparc64 GENERIC (for further 1450 information, see the respective 20130304 entry). 1451 145220130304: 1453 Recent commits to callout(9) changed the size of struct callout, 1454 so the KBI is probably heavily disturbed. Also, some functions 1455 in callout(9)/sleep(9)/sleepqueue(9)/condvar(9) KPIs were replaced 1456 by macros. Every kernel module using it won't load, so rebuild 1457 is requested. 1458 1459 The ctl device has been re-enabled in GENERIC for i386 and amd64, 1460 but does not initialize by default (because of the new CTL_DISABLE 1461 option) to save memory. To re-enable it, remove the CTL_DISABLE 1462 option from the kernel config file or set kern.cam.ctl.disable=0 1463 in /boot/loader.conf. 1464 146520130301: 1466 The ctl device has been disabled in GENERIC for i386 and amd64. 1467 This was done due to the extra memory being allocated at system 1468 initialisation time by the ctl driver which was only used if 1469 a CAM target device was created. This makes a FreeBSD system 1470 unusable on 128MB or less of RAM. 1471 147220130208: 1473 A new compression method (lz4) has been merged to -HEAD. Please 1474 refer to zpool-features(7) for more information. 1475 1476 Please refer to the "ZFS notes" section of this file for information 1477 on upgrading boot ZFS pools. 1478 147920130129: 1480 A BSD-licensed patch(1) variant has been added and is installed 1481 as bsdpatch, being the GNU version the default patch. 1482 To inverse the logic and use the BSD-licensed one as default, 1483 while having the GNU version installed as gnupatch, rebuild 1484 and install world with the WITH_BSD_PATCH knob set. 1485 148620130121: 1487 Due to the use of the new -l option to install(1) during build 1488 and install, you must take care not to directly set the INSTALL 1489 make variable in your /etc/make.conf, /etc/src.conf, or on the 1490 command line. If you wish to use the -C flag for all installs 1491 you may be able to add INSTALL+=-C to /etc/make.conf or 1492 /etc/src.conf. 1493 149420130118: 1495 The install(1) option -M has changed meaning and now takes an 1496 argument that is a file or path to append logs to. In the 1497 unlikely event that -M was the last option on the command line 1498 and the command line contained at least two files and a target 1499 directory the first file will have logs appended to it. The -M 1500 option served little practical purpose in the last decade so its 1501 use is expected to be extremely rare. 1502 150320121223: 1504 After switching to Clang as the default compiler some users of ZFS 1505 on i386 systems started to experience stack overflow kernel panics. 1506 Please consider using 'options KSTACK_PAGES=4' in such configurations. 1507 150820121222: 1509 GEOM_LABEL now mangles label names read from file system metadata. 1510 Mangling affect labels containing spaces, non-printable characters, 1511 '%' or '"'. Device names in /etc/fstab and other places may need to 1512 be updated. 1513 151420121217: 1515 By default, only the 10 most recent kernel dumps will be saved. To 1516 restore the previous behaviour (no limit on the number of kernel dumps 1517 stored in the dump directory) add the following line to /etc/rc.conf: 1518 1519 savecore_flags="" 1520 152120121201: 1522 With the addition of auditdistd(8), a new auditdistd user is now 1523 required during installworld. "mergemaster -p" can be used to 1524 add the user prior to installworld, as documented in the handbook. 1525 152620121117: 1527 The sin6_scope_id member variable in struct sockaddr_in6 is now 1528 filled by the kernel before passing the structure to the userland via 1529 sysctl or routing socket. This means the KAME-specific embedded scope 1530 id in sin6_addr.s6_addr[2] is always cleared in userland application. 1531 This behavior can be controlled by net.inet6.ip6.deembed_scopeid. 1532 __FreeBSD_version is bumped to 1000025. 1533 153420121105: 1535 On i386 and amd64 systems WITH_CLANG_IS_CC is now the default. 1536 This means that the world and kernel will be compiled with clang 1537 and that clang will be installed as /usr/bin/cc, /usr/bin/c++, 1538 and /usr/bin/cpp. To disable this behavior and revert to building 1539 with gcc, compile with WITHOUT_CLANG_IS_CC. Really old versions 1540 of current may need to bootstrap WITHOUT_CLANG first if the clang 1541 build fails (its compatibility window doesn't extend to the 9 stable 1542 branch point). 1543 154420121102: 1545 The IPFIREWALL_FORWARD kernel option has been removed. Its 1546 functionality now turned on by default. 1547 154820121023: 1549 The ZERO_COPY_SOCKET kernel option has been removed and 1550 split into SOCKET_SEND_COW and SOCKET_RECV_PFLIP. 1551 NB: SOCKET_SEND_COW uses the VM page based copy-on-write 1552 mechanism which is not safe and may result in kernel crashes. 1553 NB: The SOCKET_RECV_PFLIP mechanism is useless as no current 1554 driver supports disposeable external page sized mbuf storage. 1555 Proper replacements for both zero-copy mechanisms are under 1556 consideration and will eventually lead to complete removal 1557 of the two kernel options. 1558 155920121023: 1560 The IPv4 network stack has been converted to network byte 1561 order. The following modules need to be recompiled together 1562 with kernel: carp(4), divert(4), gif(4), siftr(4), gre(4), 1563 pf(4), ipfw(4), ng_ipfw(4), stf(4). 1564 156520121022: 1566 Support for non-MPSAFE filesystems was removed from VFS. The 1567 VFS_VERSION was bumped, all filesystem modules shall be 1568 recompiled. 1569 157020121018: 1571 All the non-MPSAFE filesystems have been disconnected from 1572 the build. The full list includes: codafs, hpfs, ntfs, nwfs, 1573 portalfs, smbfs, xfs. 1574 157520121016: 1576 The interface cloning API and ABI has changed. The following 1577 modules need to be recompiled together with kernel: 1578 ipfw(4), pfsync(4), pflog(4), usb(4), wlan(4), stf(4), 1579 vlan(4), disc(4), edsc(4), if_bridge(4), gif(4), tap(4), 1580 faith(4), epair(4), enc(4), tun(4), if_lagg(4), gre(4). 1581 158220121015: 1583 The sdhci driver was split in two parts: sdhci (generic SD Host 1584 Controller logic) and sdhci_pci (actual hardware driver). 1585 No kernel config modifications are required, but if you 1586 load sdhc as a module you must switch to sdhci_pci instead. 1587 158820121014: 1589 Import the FUSE kernel and userland support into base system. 1590 159120121013: 1592 The GNU sort(1) program has been removed since the BSD-licensed 1593 sort(1) has been the default for quite some time and no serious 1594 problems have been reported. The corresponding WITH_GNU_SORT 1595 knob has also gone. 1596 159720121006: 1598 The pfil(9) API/ABI for AF_INET family has been changed. Packet 1599 filtering modules: pf(4), ipfw(4), ipfilter(4) need to be recompiled 1600 with new kernel. 1601 160220121001: 1603 The net80211(4) ABI has been changed to allow for improved driver 1604 PS-POLL and power-save support. All wireless drivers need to be 1605 recompiled to work with the new kernel. 1606 160720120913: 1608 The random(4) support for the VIA hardware random number 1609 generator (`PADLOCK') is no longer enabled unconditionally. 1610 Add the padlock_rng device in the custom kernel config if 1611 needed. The GENERIC kernels on i386 and amd64 do include the 1612 device, so the change only affects the custom kernel 1613 configurations. 1614 161520120908: 1616 The pf(4) packet filter ABI has been changed. pfctl(8) and 1617 snmp_pf module need to be recompiled to work with new kernel. 1618 161920120828: 1620 A new ZFS feature flag "com.delphix:empty_bpobj" has been merged 1621 to -HEAD. Pools that have empty_bpobj in active state can not be 1622 imported read-write with ZFS implementations that do not support 1623 this feature. For more information read the zpool-features(5) 1624 manual page. 1625 162620120727: 1627 The sparc64 ZFS loader has been changed to no longer try to auto- 1628 detect ZFS providers based on diskN aliases but now requires these 1629 to be explicitly listed in the OFW boot-device environment variable. 1630 163120120712: 1632 The OpenSSL has been upgraded to 1.0.1c. Any binaries requiring 1633 libcrypto.so.6 or libssl.so.6 must be recompiled. Also, there are 1634 configuration changes. Make sure to merge /etc/ssl/openssl.cnf. 1635 163620120712: 1637 The following sysctls and tunables have been renamed for consistency 1638 with other variables: 1639 kern.cam.da.da_send_ordered -> kern.cam.da.send_ordered 1640 kern.cam.ada.ada_send_ordered -> kern.cam.ada.send_ordered 1641 164220120628: 1643 The sort utility has been replaced with BSD sort. For now, GNU sort 1644 is also available as "gnusort" or the default can be set back to 1645 GNU sort by setting WITH_GNU_SORT. In this case, BSD sort will be 1646 installed as "bsdsort". 1647 164820120611: 1649 A new version of ZFS (pool version 5000) has been merged to -HEAD. 1650 Starting with this version the old system of ZFS pool versioning 1651 is superseded by "feature flags". This concept enables forward 1652 compatibility against certain future changes in functionality of ZFS 1653 pools. The first read-only compatible "feature flag" for ZFS pools 1654 is named "com.delphix:async_destroy". For more information 1655 read the new zpool-features(5) manual page. 1656 Please refer to the "ZFS notes" section of this file for information 1657 on upgrading boot ZFS pools. 1658 165920120417: 1660 The malloc(3) implementation embedded in libc now uses sources imported 1661 as contrib/jemalloc. The most disruptive API change is to 1662 /etc/malloc.conf. If your system has an old-style /etc/malloc.conf, 1663 delete it prior to installworld, and optionally re-create it using the 1664 new format after rebooting. See malloc.conf(5) for details 1665 (specifically the TUNING section and the "opt.*" entries in the MALLCTL 1666 NAMESPACE section). 1667 166820120328: 1669 Big-endian MIPS TARGET_ARCH values no longer end in "eb". mips64eb 1670 is now spelled mips64. mipsn32eb is now spelled mipsn32. mipseb is 1671 now spelled mips. This is to aid compatibility with third-party 1672 software that expects this naming scheme in uname(3). Little-endian 1673 settings are unchanged. If you are updating a big-endian mips64 machine 1674 from before this change, you may need to set MACHINE_ARCH=mips64 in 1675 your environment before the new build system will recognize your machine. 1676 167720120306: 1678 Disable by default the option VFS_ALLOW_NONMPSAFE for all supported 1679 platforms. 1680 168120120229: 1682 Now unix domain sockets behave "as expected" on nullfs(5). Previously 1683 nullfs(5) did not pass through all behaviours to the underlying layer, 1684 as a result if we bound to a socket on the lower layer we could connect 1685 only to the lower path; if we bound to the upper layer we could connect 1686 only to the upper path. The new behavior is one can connect to both the 1687 lower and the upper paths regardless what layer path one binds to. 1688 168920120211: 1690 The getifaddrs upgrade path broken with 20111215 has been restored. 1691 If you have upgraded in between 20111215 and 20120209 you need to 1692 recompile libc again with your kernel. You still need to recompile 1693 world to be able to configure CARP but this restriction already 1694 comes from 20111215. 1695 169620120114: 1697 The set_rcvar() function has been removed from /etc/rc.subr. All 1698 base and ports rc.d scripts have been updated, so if you have a 1699 port installed with a script in /usr/local/etc/rc.d you can either 1700 hand-edit the rcvar= line, or reinstall the port. 1701 1702 An easy way to handle the mass-update of /etc/rc.d: 1703 rm /etc/rc.d/* && mergemaster -i 1704 170520120109: 1706 panic(9) now stops other CPUs in the SMP systems, disables interrupts 1707 on the current CPU and prevents other threads from running. 1708 This behavior can be reverted using the kern.stop_scheduler_on_panic 1709 tunable/sysctl. 1710 The new behavior can be incompatible with kern.sync_on_panic. 1711 171220111215: 1713 The carp(4) facility has been changed significantly. Configuration 1714 of the CARP protocol via ifconfig(8) has changed, as well as format 1715 of CARP events submitted to devd(8) has changed. See manual pages 1716 for more information. The arpbalance feature of carp(4) is currently 1717 not supported anymore. 1718 1719 Size of struct in_aliasreq, struct in6_aliasreq has changed. User 1720 utilities using SIOCAIFADDR, SIOCAIFADDR_IN6, e.g. ifconfig(8), 1721 need to be recompiled. 1722 172320111122: 1724 The acpi_wmi(4) status device /dev/wmistat has been renamed to 1725 /dev/wmistat0. 1726 172720111108: 1728 The option VFS_ALLOW_NONMPSAFE option has been added in order to 1729 explicitely support non-MPSAFE filesystems. 1730 It is on by default for all supported platform at this present 1731 time. 1732 173320111101: 1734 The broken amd(4) driver has been replaced with esp(4) in the amd64, 1735 i386 and pc98 GENERIC kernel configuration files. 1736 173720110930: 1738 sysinstall has been removed 1739 174020110923: 1741 The stable/9 branch created in subversion. This corresponds to the 1742 RELENG_9 branch in CVS. 1743 1744COMMON ITEMS: 1745 1746 General Notes 1747 ------------- 1748 Avoid using make -j when upgrading. While generally safe, there are 1749 sometimes problems using -j to upgrade. If your upgrade fails with 1750 -j, please try again without -j. From time to time in the past there 1751 have been problems using -j with buildworld and/or installworld. This 1752 is especially true when upgrading between "distant" versions (eg one 1753 that cross a major release boundary or several minor releases, or when 1754 several months have passed on the -current branch). 1755 1756 Sometimes, obscure build problems are the result of environment 1757 poisoning. This can happen because the make utility reads its 1758 environment when searching for values for global variables. To run 1759 your build attempts in an "environmental clean room", prefix all make 1760 commands with 'env -i '. See the env(1) manual page for more details. 1761 1762 When upgrading from one major version to another it is generally best to 1763 upgrade to the latest code in the currently installed branch first, then 1764 do an upgrade to the new branch. This is the best-tested upgrade path, 1765 and has the highest probability of being successful. Please try this 1766 approach if you encounter problems with a major version upgrade. Since 1767 the stable 4.x branch point, one has generally been able to upgade from 1768 anywhere in the most recent stable branch to head / current (or even the 1769 last couple of stable branches). See the top of this file when there's 1770 an exception. 1771 1772 When upgrading a live system, having a root shell around before 1773 installing anything can help undo problems. Not having a root shell 1774 around can lead to problems if pam has changed too much from your 1775 starting point to allow continued authentication after the upgrade. 1776 1777 This file should be read as a log of events. When a later event changes 1778 information of a prior event, the prior event should not be deleted. 1779 Instead, a pointer to the entry with the new information should be 1780 placed in the old entry. Readers of this file should also sanity check 1781 older entries before relying on them blindly. Authors of new entries 1782 should write them with this in mind. 1783 1784 ZFS notes 1785 --------- 1786 When upgrading the boot ZFS pool to a new version, always follow 1787 these two steps: 1788 1789 1.) recompile and reinstall the ZFS boot loader and boot block 1790 (this is part of "make buildworld" and "make installworld") 1791 1792 2.) update the ZFS boot block on your boot drive 1793 1794 The following example updates the ZFS boot block on the first 1795 partition (freebsd-boot) of a GPT partitioned drive ada0: 1796 "gpart bootcode -p /boot/gptzfsboot -i 1 ada0" 1797 1798 Non-boot pools do not need these updates. 1799 1800 To build a kernel 1801 ----------------- 1802 If you are updating from a prior version of FreeBSD (even one just 1803 a few days old), you should follow this procedure. It is the most 1804 failsafe as it uses a /usr/obj tree with a fresh mini-buildworld, 1805 1806 make kernel-toolchain 1807 make -DALWAYS_CHECK_MAKE buildkernel KERNCONF=YOUR_KERNEL_HERE 1808 make -DALWAYS_CHECK_MAKE installkernel KERNCONF=YOUR_KERNEL_HERE 1809 1810 To test a kernel once 1811 --------------------- 1812 If you just want to boot a kernel once (because you are not sure 1813 if it works, or if you want to boot a known bad kernel to provide 1814 debugging information) run 1815 make installkernel KERNCONF=YOUR_KERNEL_HERE KODIR=/boot/testkernel 1816 nextboot -k testkernel 1817 1818 To just build a kernel when you know that it won't mess you up 1819 -------------------------------------------------------------- 1820 This assumes you are already running a CURRENT system. Replace 1821 ${arch} with the architecture of your machine (e.g. "i386", 1822 "arm", "amd64", "ia64", "pc98", "sparc64", "powerpc", "mips", etc). 1823 1824 cd src/sys/${arch}/conf 1825 config KERNEL_NAME_HERE 1826 cd ../compile/KERNEL_NAME_HERE 1827 make depend 1828 make 1829 make install 1830 1831 If this fails, go to the "To build a kernel" section. 1832 1833 To rebuild everything and install it on the current system. 1834 ----------------------------------------------------------- 1835 # Note: sometimes if you are running current you gotta do more than 1836 # is listed here if you are upgrading from a really old current. 1837 1838 <make sure you have good level 0 dumps> 1839 make buildworld 1840 make kernel KERNCONF=YOUR_KERNEL_HERE 1841 [1] 1842 <reboot in single user> [3] 1843 mergemaster -Fp [5] 1844 make installworld 1845 mergemaster -Fi [4] 1846 make delete-old [6] 1847 <reboot> 1848 1849 To cross-install current onto a separate partition 1850 -------------------------------------------------- 1851 # In this approach we use a separate partition to hold 1852 # current's root, 'usr', and 'var' directories. A partition 1853 # holding "/", "/usr" and "/var" should be about 2GB in 1854 # size. 1855 1856 <make sure you have good level 0 dumps> 1857 <boot into -stable> 1858 make buildworld 1859 make buildkernel KERNCONF=YOUR_KERNEL_HERE 1860 <maybe newfs current's root partition> 1861 <mount current's root partition on directory ${CURRENT_ROOT}> 1862 make installworld DESTDIR=${CURRENT_ROOT} -DDB_FROM_SRC 1863 make distribution DESTDIR=${CURRENT_ROOT} # if newfs'd 1864 make installkernel KERNCONF=YOUR_KERNEL_HERE DESTDIR=${CURRENT_ROOT} 1865 cp /etc/fstab ${CURRENT_ROOT}/etc/fstab # if newfs'd 1866 <edit ${CURRENT_ROOT}/etc/fstab to mount "/" from the correct partition> 1867 <reboot into current> 1868 <do a "native" rebuild/install as described in the previous section> 1869 <maybe install compatibility libraries from ports/misc/compat*> 1870 <reboot> 1871 1872 1873 To upgrade in-place from stable to current 1874 ---------------------------------------------- 1875 <make sure you have good level 0 dumps> 1876 make buildworld [9] 1877 make kernel KERNCONF=YOUR_KERNEL_HERE [8] 1878 [1] 1879 <reboot in single user> [3] 1880 mergemaster -Fp [5] 1881 make installworld 1882 mergemaster -Fi [4] 1883 make delete-old [6] 1884 <reboot> 1885 1886 Make sure that you've read the UPDATING file to understand the 1887 tweaks to various things you need. At this point in the life 1888 cycle of current, things change often and you are on your own 1889 to cope. The defaults can also change, so please read ALL of 1890 the UPDATING entries. 1891 1892 Also, if you are tracking -current, you must be subscribed to 1893 freebsd-current@freebsd.org. Make sure that before you update 1894 your sources that you have read and understood all the recent 1895 messages there. If in doubt, please track -stable which has 1896 much fewer pitfalls. 1897 1898 [1] If you have third party modules, such as vmware, you 1899 should disable them at this point so they don't crash your 1900 system on reboot. 1901 1902 [3] From the bootblocks, boot -s, and then do 1903 fsck -p 1904 mount -u / 1905 mount -a 1906 cd src 1907 adjkerntz -i # if CMOS is wall time 1908 Also, when doing a major release upgrade, it is required that 1909 you boot into single user mode to do the installworld. 1910 1911 [4] Note: This step is non-optional. Failure to do this step 1912 can result in a significant reduction in the functionality of the 1913 system. Attempting to do it by hand is not recommended and those 1914 that pursue this avenue should read this file carefully, as well 1915 as the archives of freebsd-current and freebsd-hackers mailing lists 1916 for potential gotchas. The -U option is also useful to consider. 1917 See mergemaster(8) for more information. 1918 1919 [5] Usually this step is a noop. However, from time to time 1920 you may need to do this if you get unknown user in the following 1921 step. It never hurts to do it all the time. You may need to 1922 install a new mergemaster (cd src/usr.sbin/mergemaster && make 1923 install) after the buildworld before this step if you last updated 1924 from current before 20130425 or from -stable before 20130430. 1925 1926 [6] This only deletes old files and directories. Old libraries 1927 can be deleted by "make delete-old-libs", but you have to make 1928 sure that no program is using those libraries anymore. 1929 1930 [8] In order to have a kernel that can run the 4.x binaries needed to 1931 do an installworld, you must include the COMPAT_FREEBSD4 option in 1932 your kernel. Failure to do so may leave you with a system that is 1933 hard to boot to recover. A similar kernel option COMPAT_FREEBSD5 is 1934 required to run the 5.x binaries on more recent kernels. And so on 1935 for COMPAT_FREEBSD6 and COMPAT_FREEBSD7. 1936 1937 Make sure that you merge any new devices from GENERIC since the 1938 last time you updated your kernel config file. 1939 1940 [9] When checking out sources, you must include the -P flag to have 1941 cvs prune empty directories. 1942 1943 If CPUTYPE is defined in your /etc/make.conf, make sure to use the 1944 "?=" instead of the "=" assignment operator, so that buildworld can 1945 override the CPUTYPE if it needs to. 1946 1947 MAKEOBJDIRPREFIX must be defined in an environment variable, and 1948 not on the command line, or in /etc/make.conf. buildworld will 1949 warn if it is improperly defined. 1950FORMAT: 1951 1952This file contains a list, in reverse chronological order, of major 1953breakages in tracking -current. It is not guaranteed to be a complete 1954list of such breakages, and only contains entries since September 23, 2011. 1955If you need to see UPDATING entries from before that date, you will need 1956to fetch an UPDATING file from an older FreeBSD release. 1957 1958Copyright information: 1959 1960Copyright 1998-2009 M.
