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 5420171010: 55 libstand has turned into a private library for sys/boot use only. 56 It is no longer supported as a public interface outside of sys/boot. 57 5820171005: 59 The arm port has split armv6 into armv6 and armv7. armv7 is now 60 a valid TARGET_ARCH/MACHINE_ARCH setting. If you have an armv7 system 61 and are running a kernel from before r324363, you will need to add 62 MACHINE_ARCH=armv7 to 'make buildworld' to do a native build. 63 6420171003: 65 When building multiple kernels using KERNCONF, non-existent KERNCONF 66 files will produce an error and buildkernel will fail. Previously 67 missing KERNCONF files silently failed giving no indication as to 68 why, only to subsequently discover during installkernel that the 69 desired kernel was never built in the first place. 70 7120170912: 72 The default serial number format for CTL LUNs has changed. This will 73 affect users who use /dev/diskid/* device nodes, or whose FibreChannel 74 or iSCSI clients care about their LUNs' serial numbers. Users who 75 require serial number stability should hardcode serial numbers in 76 /etc/ctl.conf . 77 7820170912: 79 For 32-bit arm compiled for hard-float support, soft-floating point 80 binaries now always get their shared libraries from 81 LD_SOFT_LIBRARY_PATH (in the past, this was only used if 82 /usr/libsoft also existed). Only users with a hard-float ld.so, but 83 soft-float everything else should be affected. 84 8520170826: 86 The geli password typed at boot is now hidden. To restore the previous 87 behavior, see geli(8) for configuration options. 88 8920170825: 90 Move PMTUD blackhole counters to TCPSTATS and remove them from bare 91 sysctl values. Minor nit, but requires a rebuild of both world/kernel 92 to complete. 93 9420170814: 95 "make check" behavior (made in ^/head@r295380) has been changed to 96 execute from a limited sandbox, as opposed to executing from 97 ${TESTSDIR}. 98 99 Behavioral changes: 100 - The "beforecheck" and "aftercheck" targets are now specified. 101 - ${CHECKDIR} (added in commit noted above) has been removed. 102 - Legacy behavior can be enabled by setting 103 WITHOUT_MAKE_CHECK_USE_SANDBOX in src.conf(5) or the environment. 104 105 If the limited sandbox mode is enabled, "make check" will execute 106 "make distribution", then install, execute the tests, and clean up the 107 sandbox if successful. 108 109 The "make distribution" and "make install" targets are typically run as 110 root to set appropriate permissions and ownership at installation time. 111 The end-user should set "WITH_INSTALL_AS_USER" in src.conf(5) or the 112 environment if executing "make check" with limited sandbox mode using 113 an unprivileged user. 114 11520170808: 116 Since the switch to GPT disk labels, fsck for UFS/FFS has been 117 unable to automatically find alternate superblocks. As of r322297, 118 the information needed to find alternate superblocks has been 119 moved to the end of the area reserved for the boot block. 120 Filesystems created with a newfs of this vintage or later 121 will create the recovery information. If you have a filesystem 122 created prior to this change and wish to have a recovery block 123 created for your filesystem, you can do so by running fsck in 124 forground mode (i.e., do not use the -p or -y options). As it 125 starts, fsck will ask ``SAVE DATA TO FIND ALTERNATE SUPERBLOCKS'' 126 to which you should answer yes. 127 12820170728: 129 As of r321665, an NFSv4 server configuration that services 130 Kerberos mounts or clients that do not support the uid/gid in 131 owner/owner_group string capability, must explicitly enable 132 the nfsuserd daemon by adding nfsuserd_enable="YES" to the 133 machine's /etc/rc.conf file. 134 13520170722: 136 Clang, llvm, lldb, compiler-rt and libc++ have been upgraded to 5.0.0. 137 Please see the 20141231 entry below for information about prerequisites 138 and upgrading, if you are not already using clang 3.5.0 or higher. 139 14020170701: 141 WITHOUT_RCMDS is now the default. Set WITH_RCMDS if you need the 142 r-commands (rlogin, rsh, etc.) to be built with the base system. 143 14420170625: 145 The FreeBSD/powerpc platform now uses a 64-bit type for time_t. This is 146 a very major ABI incompatible change, so users of FreeBSD/powerpc must 147 be careful when performing source upgrades. It is best to run 148 'make installworld' from an alternate root system, either a live 149 CD/memory stick, or a temporary root partition. Additionally, all ports 150 must be recompiled. powerpc64 is largely unaffected, except in the case 151 of 32-bit compatibility. All 32-bit binaries will be affected. 152 15320170623: 154 Forward compatibility for the "ino64" project have been committed. This 155 will allow most new binaries to run on older kernels in a limited 156 fashion. This prevents many of the common foot-shooting actions in the 157 upgrade as well as the limited ability to roll back the kernel across 158 the ino64 upgrade. Complicated use cases may not work properly, though 159 enough simpler ones work to allow recovery in most situations. 160 16120170620: 162 Switch back to the BSDL dtc (Device Tree Compiler). Set WITH_GPL_DTC 163 if you require the GPL compiler. 164 16520170618: 166 The internal ABI used for communication between the NFS kernel modules 167 was changed by r320085, so __FreeBSD_version was bumped to 168 ensure all the NFS related modules are updated together. 169 17020170617: 171 The ABI of struct event was changed by extending the data 172 member to 64bit and adding ext fields. For upgrade, same 173 precautions as for the entry 20170523 "ino64" must be 174 followed. 175 17620170531: 177 The GNU roff toolchain has been removed from base. To render manpages 178 which are not supported by mandoc(1), man(1) can fallback on GNU roff 179 from ports (and recommends to install it). 180 To render roff(7) documents, consider using GNU roff from ports or the 181 heirloom doctools roff toolchain from ports via pkg install groff or 182 via pkg install heirloom-doctools. 183 18420170524: 185 The ath(4) and ath_hal(4) modules now build piecemeal to allow for 186 smaller runtime footprint builds. This is useful for embedded systems 187 which only require one chipset support. 188 189 If you load it as a module, make sure this is in /boot/loader.conf: 190 191 if_ath_load="YES" 192 193 This will load the HAL, all chip/RF backends and if_ath_pci. 194 If you have if_ath_pci in /boot/loader.conf, ensure it is after 195 if_ath or it will not load any HAL chipset support. 196 197 If you want to selectively load things (eg on ye cheape ARM/MIPS 198 platforms where RAM is at a premium) you should: 199 200 * load ath_hal 201 * load the chip modules in question 202 * load ath_rate, ath_dfs 203 * load ath_main 204 * load if_ath_pci and/or if_ath_ahb depending upon your particular 205 bus bind type - this is where probe/attach is done. 206 207 For further comments/feedback, poke adrian@ . 208 20920170523: 210 The "ino64" 64-bit inode project has been committed, which extends 211 a number of types to 64 bits. Upgrading in place requires care and 212 adherence to the documented upgrade procedure. 213 214 If using a custom kernel configuration ensure that the 215 COMPAT_FREEBSD11 option is included (as during the upgrade the 216 system will be running the ino64 kernel with the existing world). 217 218 For the safest in-place upgrade begin by removing previous build 219 artifacts via "rm -rf /usr/obj/*". Then, carefully follow the 220 full procedure documented below under the heading "To rebuild 221 everything and install it on the current system." Specifically, 222 a reboot is required after installing the new kernel before 223 installing world. 224 22520170424: 226 The NATM framework including the en(4), fatm(4), hatm(4), and 227 patm(4) devices has been removed. Consumers should plan a 228 migration before the end-of-life date for FreeBSD 11. 229 23020170420: 231 GNU diff has been replaced by a BSD licensed diff. Some features of GNU 232 diff has not been implemented, if those are needed a newer version of 233 GNU diff is available via the diffutils package under the gdiff name. 234 23520170413: 236 As of r316810 for ipfilter, keep frags is no longer assumed when 237 keep state is specified in a rule. r316810 aligns ipfilter with 238 documentation in man pages separating keep frags from keep state. 239 This allows keep state to be specified without forcing keep frags 240 and allows keep frags to be specified independently of keep state. 241 To maintain previous behaviour, also specify keep frags with 242 keep state (as documented in ipf.conf.5). 243 24420170407: 245 arm64 builds now use the base system LLD 4.0.0 linker by default, 246 instead of requiring that the aarch64-binutils port or package be 247 installed. To continue using aarch64-binutils, set 248 CROSS_BINUTILS_PREFIX=/usr/local/aarch64-freebsd/bin . 249 25020170405: 251 The UDP optimization in entry 20160818 that added the sysctl 252 net.inet.udp.require_l2_bcast has been reverted. L2 broadcast 253 packets will no longer be treated as L3 broadcast packets. 254 25520170331: 256 Binds and sends to the loopback addresses, IPv6 and IPv4, will now 257 use any explicitly assigned loopback address available in the jail 258 instead of using the first assigned address of the jail. 259 26020170329: 261 The ctl.ko module no longer implements the iSCSI target frontend: 262 cfiscsi.ko does instead. 263 264 If building cfiscsi.ko as a kernel module, the module can be loaded 265 via one of the following methods: 266 - `cfiscsi_load="YES"` in loader.conf(5). 267 - Add `cfiscsi` to `$kld_list` in rc.conf(5). 268 - ctladm(8)/ctld(8), when compiled with iSCSI support 269 (`WITH_ISCSI=yes` in src.conf(5)) 270 271 Please see cfiscsi(4) for more details. 272 27320170316: 274 The mmcsd.ko module now additionally depends on geom_flashmap.ko. 275 Also, mmc.ko and mmcsd.ko need to be a matching pair built from the 276 same source (previously, the dependency of mmcsd.ko on mmc.ko was 277 missing, but mmcsd.ko now will refuse to load if it is incompatible 278 with mmc.ko). 279 28020170315: 281 The syntax of ipfw(8) named states was changed to avoid ambiguity. 282 If you have used named states in the firewall rules, you need to modify 283 them after installworld and before rebooting. Now named states must 284 be prefixed with colon. 285 28620170311: 287 The old drm (sys/dev/drm/) drivers for i915 and radeon have been 288 removed as the userland we provide cannot use them. The KMS version 289 (sys/dev/drm2) supports the same hardware. 290 29120170302: 292 Clang, llvm, lldb, compiler-rt and libc++ have been upgraded to 4.0.0. 293 Please see the 20141231 entry below for information about prerequisites 294 and upgrading, if you are not already using clang 3.5.0 or higher. 295 29620170221: 297 The code that provides support for ZFS .zfs/ directory functionality 298 has been reimplemented. It's not possible now to create a snapshot 299 by mkdir under .zfs/snapshot/. That should be the only user visible 300 change. 301 30220170216: 303 EISA bus support has been removed. The WITH_EISA option is no longer 304 valid. 305 30620170215: 307 MCA bus support has been removed. 308 30920170127: 310 The WITH_LLD_AS_LD / WITHOUT_LLD_AS_LD build knobs have been renamed 311 WITH_LLD_IS_LD / WITHOUT_LLD_IS_LD, for consistency with CLANG_IS_CC. 312 31320170112: 314 The EM_MULTIQUEUE kernel configuration option is deprecated now that 315 the em(4) driver conforms to iflib specifications. 316 31720170109: 318 The igb(4), em(4) and lem(4) ethernet drivers are now implemented via 319 IFLIB. If you have a custom kernel configuration that excludes em(4) 320 but you use igb(4), you need to re-add em(4) to your custom configuration. 321 32220161217: 323 Clang, llvm, lldb, compiler-rt and libc++ have been upgraded to 3.9.1. 324 Please see the 20141231 entry below for information about prerequisites 325 and upgrading, if you are not already using clang 3.5.0 or higher. 326 32720161124: 328 Clang, llvm, lldb, compiler-rt and libc++ have been upgraded to 3.9.0. 329 Please see the 20141231 entry below for information about prerequisites 330 and upgrading, if you are not already using clang 3.5.0 or higher. 331 33220161119: 333 The layout of the pmap structure has changed for powerpc to put the pmap 334 statistics at the front for all CPU variations. libkvm(3) and all tools 335 that link against it need to be recompiled. 336 33720161030: 338 isl(4) and cyapa(4) drivers now require a new driver, 339 chromebook_platform(4), to work properly on Chromebook-class hardware. 340 On other types of hardware the drivers may need to be configured using 341 device hints. Please see the corresponding manual pages for details. 342 34320161017: 344 The urtwn(4) driver was merged into rtwn(4) and now consists of 345 rtwn(4) main module + rtwn_usb(4) and rtwn_pci(4) bus-specific 346 parts. 347 Also, firmware for RTL8188CE was renamed due to possible name 348 conflict (rtwnrtl8192cU(B) -> rtwnrtl8192cE(B)) 349 35020161015: 351 GNU rcs has been removed from base. It is available as packages: 352 - rcs: Latest GPLv3 GNU rcs version. 353 - rcs57: Copy of the latest version of GNU rcs (GPLv2) before it was 354 removed from base. 355 35620161008: 357 Use of the cc_cdg, cc_chd, cc_hd, or cc_vegas congestion control 358 modules now requires that the kernel configuration contain the 359 TCP_HHOOK option. (This option is included in the GENERIC kernel.) 360 36120161003: 362 The WITHOUT_ELFCOPY_AS_OBJCOPY src.conf(5) knob has been retired. 363 ELF Tool Chain's elfcopy is always installed as /usr/bin/objcopy. 364 36520160924: 366 Relocatable object files with the extension of .So have been renamed 367 to use an extension of .pico instead. The purpose of this change is 368 to avoid a name clash with shared libraries on case-insensitive file 369 systems. On those file systems, foo.So is the same file as foo.so. 370 37120160918: 372 GNU rcs has been turned off by default. It can (temporarily) be built 373 again by adding WITH_RCS knob in src.conf. 374 Otherwise, GNU rcs is available from packages: 375 - rcs: Latest GPLv3 GNU rcs version. 376 - rcs57: Copy of the latest version of GNU rcs (GPLv2) from base. 377 37820160918: 379 The backup_uses_rcs functionality has been removed from rc.subr. 380 38120160908: 382 The queue(3) debugging macro, QUEUE_MACRO_DEBUG, has been split into 383 two separate components, QUEUE_MACRO_DEBUG_TRACE and 384 QUEUE_MACRO_DEBUG_TRASH. Define both for the original 385 QUEUE_MACRO_DEBUG behavior. 386 38720160824: 388 r304787 changed some ioctl interfaces between the iSCSI userspace 389 programs and the kernel. ctladm, ctld, iscsictl, and iscsid must be 390 rebuilt to work with new kernels. __FreeBSD_version has been bumped 391 to 1200005. 392 39320160818: 394 The UDP receive code has been updated to only treat incoming UDP 395 packets that were addressed to an L2 broadcast address as L3 396 broadcast packets. It is not expected that this will affect any 397 standards-conforming UDP application. The new behaviour can be 398 disabled by setting the sysctl net.inet.udp.require_l2_bcast to 399 0. 400 40120160818: 402 Remove the openbsd_poll system call. 403 __FreeBSD_version has been bumped because of this. 404 40520160622: 406 The libc stub for the pipe(2) system call has been replaced with 407 a wrapper that calls the pipe2(2) system call and the pipe(2) 408 system call is now only implemented by the kernels that include 409 "options COMPAT_FREEBSD10" in their config file (this is the 410 default). Users should ensure that this option is enabled in 411 their kernel or upgrade userspace to r302092 before upgrading their 412 kernel. 413 41420160527: 415 CAM will now strip leading spaces from SCSI disks' serial numbers. 416 This will affect users who create UFS filesystems on SCSI disks using 417 those disk's diskid device nodes. For example, if /etc/fstab 418 previously contained a line like 419 "/dev/diskid/DISK-%20%20%20%20%20%20%20ABCDEFG0123456", you should 420 change it to "/dev/diskid/DISK-ABCDEFG0123456". Users of geom 421 transforms like gmirror may also be affected. ZFS users should 422 generally be fine. 423 42420160523: 425 The bitstring(3) API has been updated with new functionality and 426 improved performance. But it is binary-incompatible with the old API. 427 Objects built with the new headers may not be linked against objects 428 built with the old headers. 429 43020160520: 431 The brk and sbrk functions have been removed from libc on arm64. 432 Binutils from ports has been updated to not link to these 433 functions and should be updated to the latest version before 434 installing a new libc. 435 43620160517: 437 The armv6 port now defaults to hard float ABI. Limited support 438 for running both hardfloat and soft float on the same system 439 is available using the libraries installed with -DWITH_LIBSOFT. 440 This has only been tested as an upgrade path for installworld 441 and packages may fail or need manual intervention to run. New 442 packages will be needed. 443 444 To update an existing self-hosted armv6hf system, you must add 445 TARGET_ARCH=armv6 on the make command line for both the build 446 and the install steps. 447 44820160510: 449 Kernel modules compiled outside of a kernel build now default to 450 installing to /boot/modules instead of /boot/kernel. Many kernel 451 modules built this way (such as those in ports) already overrode 452 KMODDIR explicitly to install into /boot/modules. However, 453 manually building and installing a module from /sys/modules will 454 now install to /boot/modules instead of /boot/kernel. 455 45620160414: 457 The CAM I/O scheduler has been committed to the kernel. There should be 458 no user visible impact. This does enable NCQ Trim on ada SSDs. While the 459 list of known rogues that claim support for this but actually corrupt 460 data is believed to be complete, be on the lookout for data 461 corruption. The known rogue list is believed to be complete: 462 463 o Crucial MX100, M550 drives with MU01 firmware. 464 o Micron M510 and M550 drives with MU01 firmware. 465 o Micron M500 prior to MU07 firmware 466 o Samsung 830, 840, and 850 all firmwares 467 o FCCT M500 all firmwares 468 469 Crucial has firmware http://www.crucial.com/usa/en/support-ssd-firmware 470 with working NCQ TRIM. For Micron branded drives, see your sales rep for 471 updated firmware. Black listed drives will work correctly because these 472 drives work correctly so long as no NCQ TRIMs are sent to them. Given 473 this list is the same as found in Linux, it's believed there are no 474 other rogues in the market place. All other models from the above 475 vendors work. 476 477 To be safe, if you are at all concerned, you can quirk each of your 478 drives to prevent NCQ from being sent by setting: 479 kern.cam.ada.X.quirks="0x2" 480 in loader.conf. If the drive requires the 4k sector quirk, set the 481 quirks entry to 0x3. 482 48320160330: 484 The FAST_DEPEND build option has been removed and its functionality is 485 now the one true way. The old mkdep(1) style of 'make depend' has 486 been removed. See 20160311 for further details. 487 48820160317: 489 Resource range types have grown from unsigned long to uintmax_t. All 490 drivers, and anything using libdevinfo, need to be recompiled. 491 49220160311: 493 WITH_FAST_DEPEND is now enabled by default for in-tree and out-of-tree 494 builds. It no longer runs mkdep(1) during 'make depend', and the 495 'make depend' stage can safely be skipped now as it is auto ran 496 when building 'make all' and will generate all SRCS and DPSRCS before 497 building anything else. Dependencies are gathered at compile time with 498 -MF flags kept in separate .depend files per object file. Users should 499 run 'make cleandepend' once if using -DNO_CLEAN to clean out older 500 stale .depend files. 501 50220160306: 503 On amd64, clang 3.8.0 can now insert sections of type AMD64_UNWIND into 504 kernel modules. Therefore, if you load any kernel modules at boot time, 505 please install the boot loaders after you install the kernel, but before 506 rebooting, e.g.: 507 508 make buildworld 509 make kernel KERNCONF=YOUR_KERNEL_HERE 510 make -C sys/boot install 511 <reboot in single user> 512 513 Then follow the usual steps, described in the General Notes section, 514 below. 515 51620160305: 517 Clang, llvm, lldb and compiler-rt have been upgraded to 3.8.0. Please 518 see the 20141231 entry below for information about prerequisites and 519 upgrading, if you are not already using clang 3.5.0 or higher. 520 52120160301: 522 The AIO subsystem is now a standard part of the kernel. The 523 VFS_AIO kernel option and aio.ko kernel module have been removed. 524 Due to stability concerns, asynchronous I/O requests are only 525 permitted on sockets and raw disks by default. To enable 526 asynchronous I/O requests on all file types, set the 527 vfs.aio.enable_unsafe sysctl to a non-zero value. 528 52920160226: 530 The ELF object manipulation tool objcopy is now provided by the 531 ELF Tool Chain project rather than by GNU binutils. It should be a 532 drop-in replacement, with the addition of arm64 support. The 533 (temporary) src.conf knob WITHOUT_ELFCOPY_AS_OBJCOPY knob may be set 534 to obtain the GNU version if necessary. 535 53620160129: 537 Building ZFS pools on top of zvols is prohibited by default. That 538 feature has never worked safely; it's always been prone to deadlocks. 539 Using a zvol as the backing store for a VM guest's virtual disk will 540 still work, even if the guest is using ZFS. Legacy behavior can be 541 restored by setting vfs.zfs.vol.recursive=1. 542 54320160119: 544 The NONE and HPN patches has been removed from OpenSSH. They are 545 still available in the security/openssh-portable port. 546 54720160113: 548 With the addition of ypldap(8), a new _ypldap user is now required 549 during installworld. "mergemaster -p" can be used to add the user 550 prior to installworld, as documented in the handbook. 551 55220151216: 553 The tftp loader (pxeboot) now uses the option root-path directive. As a 554 consequence it no longer looks for a pxeboot.4th file on the tftp 555 server. Instead it uses the regular /boot infrastructure as with the 556 other loaders. 557 55820151211: 559 The code to start recording plug and play data into the modules has 560 been committed. While the old tools will properly build a new kernel, 561 a number of warnings about "unknown metadata record 4" will be produced 562 for an older kldxref. To avoid such warnings, make sure to rebuild 563 the kernel toolchain (or world). Make sure that you have r292078 or 564 later when trying to build 292077 or later before rebuilding. 565 56620151207: 567 Debug data files are now built by default with 'make buildworld' and 568 installed with 'make installworld'. This facilitates debugging but 569 requires more disk space both during the build and for the installed 570 world. Debug files may be disabled by setting WITHOUT_DEBUG_FILES=yes 571 in src.conf(5). 572 57320151130: 574 r291527 changed the internal interface between the nfsd.ko and 575 nfscommon.ko modules. As such, they must both be upgraded to-gether. 576 __FreeBSD_version has been bumped because of this. 577 57820151108: 579 Add support for unicode collation strings leads to a change of 580 order of files listed by ls(1) for example. To get back to the old 581 behaviour, set LC_COLLATE environment variable to "C". 582 583 Databases administrators will need to reindex their databases given 584 collation results will be different. 585 586 Due to a bug in install(1) it is recommended to remove the ancient 587 locales before running make installworld. 588 589 rm -rf /usr/share/locale/* 590 59120151030: 592 The OpenSSL has been upgraded to 1.0.2d. Any binaries requiring 593 libcrypto.so.7 or libssl.so.7 must be recompiled. 594 59520151020: 596 Qlogic 24xx/25xx firmware images were updated from 5.5.0 to 7.3.0. 597 Kernel modules isp_2400_multi and isp_2500_multi were removed and 598 should be replaced with isp_2400 and isp_2500 modules respectively. 599 60020151017: 601 The build previously allowed using 'make -n' to not recurse into 602 sub-directories while showing what commands would be executed, and 603 'make -n -n' to recursively show commands. Now 'make -n' will recurse 604 and 'make -N' will not. 605 60620151012: 607 If you specify SENDMAIL_MC or SENDMAIL_CF in make.conf, mergemaster 608 and etcupdate will now use this file. A custom sendmail.cf is now 609 updated via this mechanism rather than via installworld. If you had 610 excluded sendmail.cf in mergemaster.rc or etcupdate.conf, you may 611 want to remove the exclusion or change it to "always install". 612 /etc/mail/sendmail.cf is now managed the same way regardless of 613 whether SENDMAIL_MC/SENDMAIL_CF is used. If you are not using 614 SENDMAIL_MC/SENDMAIL_CF there should be no change in behavior. 615 61620151011: 617 Compatibility shims for legacy ATA device names have been removed. 618 It includes ATA_STATIC_ID kernel option, kern.cam.ada.legacy_aliases 619 and kern.geom.raid.legacy_aliases loader tunables, kern.devalias.* 620 environment variables, /dev/ad* and /dev/ar* symbolic links. 621 62220151006: 623 Clang, llvm, lldb, compiler-rt and libc++ have been upgraded to 3.7.0. 624 Please see the 20141231 entry below for information about prerequisites 625 and upgrading, if you are not already using clang 3.5.0 or higher. 626 62720150924: 628 Kernel debug files have been moved to /usr/lib/debug/boot/kernel/, 629 and renamed from .symbols to .debug. This reduces the size requirements 630 on the boot partition or file system and provides consistency with 631 userland debug files. 632 633 When using the supported kernel installation method the 634 /usr/lib/debug/boot/kernel directory will be renamed (to kernel.old) 635 as is done with /boot/kernel. 636 637 Developers wishing to maintain the historical behavior of installing 638 debug files in /boot/kernel/ can set KERN_DEBUGDIR="" in src.conf(5). 639 64020150827: 641 The wireless drivers had undergone changes that remove the 'parent 642 interface' from the ifconfig -l output. The rc.d network scripts 643 used to check presence of a parent interface in the list, so old 644 scripts would fail to start wireless networking. Thus, etcupdate(3) 645 or mergemaster(8) run is required after kernel update, to update your 646 rc.d scripts in /etc. 647 64820150827: 649 pf no longer supports 'scrub fragment crop' or 'scrub fragment drop-ovl' 650 These configurations are now automatically interpreted as 651 'scrub fragment reassemble'. 652 65320150817: 654 Kernel-loadable modules for the random(4) device are back. To use 655 them, the kernel must have 656 657 device random 658 options RANDOM_LOADABLE 659 660 kldload(8) can then be used to load random_fortuna.ko 661 or random_yarrow.ko. Please note that due to the indirect 662 function calls that the loadable modules need to provide, 663 the build-in variants will be slightly more efficient. 664 665 The random(4) kernel option RANDOM_DUMMY has been retired due to 666 unpopularity. It was not all that useful anyway. 667 66820150813: 669 The WITHOUT_ELFTOOLCHAIN_TOOLS src.conf(5) knob has been retired. 670 Control over building the ELF Tool Chain tools is now provided by 671 the WITHOUT_TOOLCHAIN knob. 672 67320150810: 674 The polarity of Pulse Per Second (PPS) capture events with the 675 uart(4) driver has been corrected. Prior to this change the PPS 676 "assert" event corresponded to the trailing edge of a positive PPS 677 pulse and the "clear" event was the leading edge of the next pulse. 678 679 As the width of a PPS pulse in a typical GPS receiver is on the 680 order of 1 millisecond, most users will not notice any significant 681 difference with this change. 682 683 Anyone who has compensated for the historical polarity reversal by 684 configuring a negative offset equal to the pulse width will need to 685 remove that workaround. 686 68720150809: 688 The default group assigned to /dev/dri entries has been changed 689 from 'wheel' to 'video' with the id of '44'. If you want to have 690 access to the dri devices please add yourself to the video group 691 with: 692 693 # pw groupmod video -m $USER 694 69520150806: 696 The menu.rc and loader.rc files will now be replaced during 697 upgrades. Please migrate local changes to menu.rc.local and 698 loader.rc.local instead. 699 70020150805: 701 GNU Binutils versions of addr2line, c++filt, nm, readelf, size, 702 strings and strip have been removed. The src.conf(5) knob 703 WITHOUT_ELFTOOLCHAIN_TOOLS no longer provides the binutils tools. 704 70520150728: 706 As ZFS requires more kernel stack pages than is the default on some 707 architectures e.g. i386, it now warns if KSTACK_PAGES is less than 708 ZFS_MIN_KSTACK_PAGES (which is 4 at the time of writing). 709 710 Please consider using 'options KSTACK_PAGES=X' where X is greater 711 than or equal to ZFS_MIN_KSTACK_PAGES i.e. 4 in such configurations. 712 71320150706: 714 sendmail has been updated to 8.15.2. Starting with FreeBSD 11.0 715 and sendmail 8.15, sendmail uses uncompressed IPv6 addresses by 716 default, i.e., they will not contain "::". For example, instead 717 of ::1, it will be 0:0:0:0:0:0:0:1. This permits a zero subnet 718 to have a more specific match, such as different map entries for 719 IPv6:0:0 vs IPv6:0. This change requires that configuration 720 data (including maps, files, classes, custom ruleset, etc.) must 721 use the same format, so make certain such configuration data is 722 upgrading. As a very simple check search for patterns like 723 'IPv6:[0-9a-fA-F:]*::' and 'IPv6::'. To return to the old 724 behavior, set the m4 option confUSE_COMPRESSED_IPV6_ADDRESSES or 725 the cf option UseCompressedIPv6Addresses. 726 72720150630: 728 The default kernel entropy-processing algorithm is now 729 Fortuna, replacing Yarrow. 730 731 Assuming you have 'device random' in your kernel config 732 file, the configurations allow a kernel option to override 733 this default. You may choose *ONE* of: 734 735 options RANDOM_YARROW # Legacy /dev/random algorithm. 736 options RANDOM_DUMMY # Blocking-only driver. 737 738 If you have neither, you get Fortuna. For most people, 739 read no further, Fortuna will give a /dev/random that works 740 like it always used to, and the difference will be irrelevant. 741 742 If you remove 'device random', you get *NO* kernel-processed 743 entropy at all. This may be acceptable to folks building 744 embedded systems, but has complications. Carry on reading, 745 and it is assumed you know what you need. 746 747 *PLEASE* read random(4) and random(9) if you are in the 748 habit of tweaking kernel configs, and/or if you are a member 749 of the embedded community, wanting specific and not-usual 750 behaviour from your security subsystems. 751 752 NOTE!! If you use RANDOM_DUMMY and/or have no 'device 753 random', you will NOT have a functioning /dev/random, and 754 many cryptographic features will not work, including SSH. 755 You may also find strange behaviour from the random(3) set 756 of library functions, in particular sranddev(3), srandomdev(3) 757 and arc4random(3). The reason for this is that the KERN_ARND 758 sysctl only returns entropy if it thinks it has some to 759 share, and with RANDOM_DUMMY or no 'device random' this 760 will never happen. 761 76220150623: 763 An additional fix for the issue described in the 20150614 sendmail 764 entry below has been been committed in revision 284717. 765 76620150616: 767 FreeBSD's old make (fmake) has been removed from the system. It is 768 available as the devel/fmake port or via pkg install fmake. 769 77020150615: 771 The fix for the issue described in the 20150614 sendmail entry 772 below has been been committed in revision 284436. The work 773 around described in that entry is no longer needed unless the 774 default setting is overridden by a confDH_PARAMETERS configuration 775 setting of '5' or pointing to a 512 bit DH parameter file. 776 77720150614: 778 ALLOW_DEPRECATED_ATF_TOOLS/ATFFILE support has been removed from 779 atf.test.mk (included from bsd.test.mk). Please upgrade devel/atf 780 and devel/kyua to version 0.20+ and adjust any calling code to work 781 with Kyuafile and kyua. 782 78320150614: 784 The import of openssl to address the FreeBSD-SA-15:10.openssl 785 security advisory includes a change which rejects handshakes 786 with DH parameters below 768 bits. sendmail releases prior 787 to 8.15.2 (not yet released), defaulted to a 512 bit 788 DH parameter setting for client connections. To work around 789 this interoperability, sendmail can be configured to use a 790 2048 bit DH parameter by: 791 792 1. Edit /etc/mail/`hostname`.mc 793 2. If a setting for confDH_PARAMETERS does not exist or 794 exists and is set to a string beginning with '5', 795 replace it with '2'. 796 3. If a setting for confDH_PARAMETERS exists and is set to 797 a file path, create a new file with: 798 openssl dhparam -out /path/to/file 2048 799 4. Rebuild the .cf file: 800 cd /etc/mail/; make; make install 801 5. Restart sendmail: 802 cd /etc/mail/; make restart 803 804 A sendmail patch is coming, at which time this file will be 805 updated. 806 80720150604: 808 Generation of legacy formatted entries have been disabled by default 809 in pwd_mkdb(8), as all base system consumers of the legacy formatted 810 entries were converted to use the new format by default when the new, 811 machine independent format have been added and supported since FreeBSD 812 5.x. 813 814 Please see the pwd_mkdb(8) manual page for further details. 815 81620150525: 817 Clang and llvm have been upgraded to 3.6.1 release. Please see the 818 20141231 entry below for information about prerequisites and upgrading, 819 if you are not already using 3.5.0 or higher. 820 82120150521: 822 TI platform code switched to using vendor DTS files and this update 823 may break existing systems running on Beaglebone, Beaglebone Black, 824 and Pandaboard: 825 826 - dtb files should be regenerated/reinstalled. Filenames are the 827 same but content is different now 828 - GPIO addressing was changed, now each GPIO bank (32 pins per bank) 829 has its own /dev/gpiocX device, e.g. pin 121 on /dev/gpioc0 in old 830 addressing scheme is now pin 25 on /dev/gpioc3. 831 - Pandaboard: /etc/ttys should be updated, serial console device is 832 now /dev/ttyu2, not /dev/ttyu0 833 83420150501: 835 soelim(1) from gnu/usr.bin/groff has been replaced by usr.bin/soelim. 836 If you need the GNU extension from groff soelim(1), install groff 837 from package: pkg install groff, or via ports: textproc/groff. 838 83920150423: 840 chmod, chflags, chown and chgrp now affect symlinks in -R mode as 841 defined in symlink(7); previously symlinks were silently ignored. 842 84320150415: 844 The const qualifier has been removed from iconv(3) to comply with 845 POSIX. The ports tree is aware of this from r384038 onwards. 846 84720150416: 848 Libraries specified by LIBADD in Makefiles must have a corresponding 849 DPADD_<lib> variable to ensure correct dependencies. This is now 850 enforced in src.libnames.mk. 851 85220150324: 853 From legacy ata(4) driver was removed support for SATA controllers 854 supported by more functional drivers ahci(4), siis(4) and mvs(4). 855 Kernel modules ataahci and ataadaptec were removed completely, 856 replaced by ahci and mvs modules respectively. 857 85820150315: 859 Clang, llvm and lldb have been upgraded to 3.6.0 release. Please see 860 the 20141231 entry below for information about prerequisites and 861 upgrading, if you are not already using 3.5.0 or higher. 862 86320150307: 864 The 32-bit PowerPC kernel has been changed to a position-independent 865 executable. This can only be booted with a version of loader(8) 866 newer than January 31, 2015, so make sure to update both world and 867 kernel before rebooting. 868 86920150217: 870 If you are running a -CURRENT kernel since r273872 (Oct 30th, 2014), 871 but before r278950, the RNG was not seeded properly. Immediately 872 upgrade the kernel to r278950 or later and regenerate any keys (e.g. 873 ssh keys or openssl keys) that were generated w/ a kernel from that 874 range. This does not affect programs that directly used /dev/random 875 or /dev/urandom. All userland uses of arc4random(3) are affected. 876 87720150210: 878 The autofs(4) ABI was changed in order to restore binary compatibility 879 with 10.1-RELEASE. The automountd(8) daemon needs to be rebuilt to work 880 with the new kernel. 881 88220150131: 883 The powerpc64 kernel has been changed to a position-independent 884 executable. This can only be booted with a new version of loader(8), 885 so make sure to update both world and kernel before rebooting. 886 88720150118: 888 Clang and llvm have been upgraded to 3.5.1 release. This is a bugfix 889 only release, no new features have been added. Please see the 20141231 890 entry below for information about prerequisites and upgrading, if you 891 are not already using 3.5.0. 892 89320150107: 894 ELF tools addr2line, elfcopy (strip), nm, size, and strings are now 895 taken from the ELF Tool Chain project rather than GNU binutils. They 896 should be drop-in replacements, with the addition of arm64 support. 897 The WITHOUT_ELFTOOLCHAIN_TOOLS= knob may be used to obtain the 898 binutils tools, if necessary. See 20150805 for updated information. 899 90020150105: 901 The default Unbound configuration now enables remote control 902 using a local socket. Users who have already enabled the 903 local_unbound service should regenerate their configuration 904 by running "service local_unbound setup" as root. 905 90620150102: 907 The GNU texinfo and GNU info pages have been removed. 908 To be able to view GNU info pages please install texinfo from ports. 909 91020141231: 911 Clang, llvm and lldb have been upgraded to 3.5.0 release. 912 913 As of this release, a prerequisite for building clang, llvm and lldb is 914 a C++11 capable compiler and C++11 standard library. This means that to 915 be able to successfully build the cross-tools stage of buildworld, with 916 clang as the bootstrap compiler, your system compiler or cross compiler 917 should either be clang 3.3 or later, or gcc 4.8 or later, and your 918 system C++ library should be libc++, or libdstdc++ from gcc 4.8 or 919 later. 920 921 On any standard FreeBSD 10.x or 11.x installation, where clang and 922 libc++ are on by default (that is, on x86 or arm), this should work out 923 of the box. 924 925 On 9.x installations where clang is enabled by default, e.g. on x86 and 926 powerpc, libc++ will not be enabled by default, so libc++ should be 927 built (with clang) and installed first. If both clang and libc++ are 928 missing, build clang first, then use it to build libc++. 929 930 On 8.x and earlier installations, upgrade to 9.x first, and then follow 931 the instructions for 9.x above. 932 933 Sparc64 and mips users are unaffected, as they still use gcc 4.2.1 by 934 default, and do not build clang. 935 936 Many embedded systems are resource constrained, and will not be able to 937 build clang in a reasonable time, or in some cases at all. In those 938 cases, cross building bootable systems on amd64 is a workaround. 939 940 This new version of clang introduces a number of new warnings, of which 941 the following are most likely to appear: 942 943 -Wabsolute-value 944 945 This warns in two cases, for both C and C++: 946 * When the code is trying to take the absolute value of an unsigned 947 quantity, which is effectively a no-op, and almost never what was 948 intended. The code should be fixed, if at all possible. If you are 949 sure that the unsigned quantity can be safely cast to signed, without 950 loss of information or undefined behavior, you can add an explicit 951 cast, or disable the warning. 952 953 * When the code is trying to take an absolute value, but the called 954 abs() variant is for the wrong type, which can lead to truncation. 955 If you want to disable the warning instead of fixing the code, please 956 make sure that truncation will not occur, or it might lead to unwanted 957 side-effects. 958 959 -Wtautological-undefined-compare and 960 -Wundefined-bool-conversion 961 962 These warn when C++ code is trying to compare 'this' against NULL, while 963 'this' should never be NULL in well-defined C++ code. However, there is 964 some legacy (pre C++11) code out there, which actively abuses this 965 feature, which was less strictly defined in previous C++ versions. 966 967 Squid and openjdk do this, for example. The warning can be turned off 968 for C++98 and earlier, but compiling the code in C++11 mode might result 969 in unexpected behavior; for example, the parts of the program that are 970 unreachable could be optimized away. 971 97220141222: 973 The old NFS client and server (kernel options NFSCLIENT, NFSSERVER) 974 kernel sources have been removed. The .h files remain, since some 975 utilities include them. This will need to be fixed later. 976 If "mount -t oldnfs ..." is attempted, it will fail. 977 If the "-o" option on mountd(8), nfsd(8) or nfsstat(1) is used, 978 the utilities will report errors. 979 98020141121: 981 The handling of LOCAL_LIB_DIRS has been altered to skip addition of 982 directories to top level SUBDIR variable when their parent 983 directory is included in LOCAL_DIRS. Users with build systems with 984 such hierarchies and without SUBDIR entries in the parent 985 directory Makefiles should add them or add the directories to 986 LOCAL_DIRS. 987 98820141109: 989 faith(4) and faithd(8) have been removed from the base system. Faith 990 has been obsolete for a very long time. 991 99220141104: 993 vt(4), the new console driver, is enabled by default. It brings 994 support for Unicode and double-width characters, as well as 995 support for UEFI and integration with the KMS kernel video 996 drivers. 997 998 You may need to update your console settings in /etc/rc.conf, 999 most probably the keymap. During boot, /etc/rc.d/syscons will 1000 indicate what you need to do. 1001 1002 vt(4) still has issues and lacks some features compared to 1003 syscons(4). See the wiki for up-to-date information: 1004 https://wiki.freebsd.org/Newcons 1005 1006 If you want to keep using syscons(4), you can do so by adding 1007 the following line to /boot/loader.conf: 1008 kern.vty=sc 1009 101020141102: 1011 pjdfstest has been integrated into kyua as an opt-in test suite. 1012 Please see share/doc/pjdfstest/README for more details on how to 1013 execute it. 1014 101520141009: 1016 gperf has been removed from the base system for architectures 1017 that use clang. Ports that require gperf will obtain it from the 1018 devel/gperf port. 1019 102020140923: 1021 pjdfstest has been moved from tools/regression/pjdfstest to 1022 contrib/pjdfstest . 1023 102420140922: 1025 At svn r271982, The default linux compat kernel ABI has been adjusted 1026 to 2.6.18 in support of the linux-c6 compat ports infrastructure 1027 update. If you wish to continue using the linux-f10 compat ports, 1028 add compat.linux.osrelease=2.6.16 to your local sysctl.conf. Users are 1029 encouraged to update their linux-compat packages to linux-c6 during 1030 their next update cycle. 1031 103220140729: 1033 The ofwfb driver, used to provide a graphics console on PowerPC when 1034 using vt(4), no longer allows mmap() of all physical memory. This 1035 will prevent Xorg on PowerPC with some ATI graphics cards from 1036 initializing properly unless x11-servers/xorg-server is updated to 1037 1.12.4_8 or newer. 1038 103920140723: 1040 The xdev targets have been converted to using TARGET and 1041 TARGET_ARCH instead of XDEV and XDEV_ARCH. 1042 104320140719: 1044 The default unbound configuration has been modified to address 1045 issues with reverse lookups on networks that use private 1046 address ranges. If you use the local_unbound service, run 1047 "service local_unbound setup" as root to regenerate your 1048 configuration, then "service local_unbound reload" to load the 1049 new configuration. 1050 105120140709: 1052 The GNU texinfo and GNU info pages are not built and installed 1053 anymore, WITH_INFO knob has been added to allow to built and install 1054 them again. 1055 UPDATE: see 20150102 entry on texinfo's removal 1056 105720140708: 1058 The GNU readline library is now an INTERNALLIB - that is, it is 1059 statically linked into consumers (GDB and variants) in the base 1060 system, and the shared library is no longer installed. The 1061 devel/readline port is available for third party software that 1062 requires readline. 1063 106420140702: 1065 The Itanium architecture (ia64) has been removed from the list of 1066 known architectures. This is the first step in the removal of the 1067 architecture. 1068 106920140701: 1070 Commit r268115 has added NFSv4.1 server support, merged from 1071 projects/nfsv4.1-server. Since this includes changes to the 1072 internal interfaces between the NFS related modules, a full 1073 build of the kernel and modules will be necessary. 1074 __FreeBSD_version has been bumped. 1075 107620140629: 1077 The WITHOUT_VT_SUPPORT kernel config knob has been renamed 1078 WITHOUT_VT. (The other _SUPPORT knobs have a consistent meaning 1079 which differs from the behaviour controlled by this knob.) 1080 108120140619: 1082 Maximal length of the serial number in CTL was increased from 16 to 1083 64 chars, that breaks ABI. All CTL-related tools, such as ctladm 1084 and ctld, need to be rebuilt to work with a new kernel. 1085 108620140606: 1087 The libatf-c and libatf-c++ major versions were downgraded to 0 and 1088 1 respectively to match the upstream numbers. They were out of 1089 sync because, when they were originally added to FreeBSD, the 1090 upstream versions were not respected. These libraries are private 1091 and not yet built by default, so renumbering them should be a 1092 non-issue. However, unclean source trees will yield broken test 1093 programs once the operator executes "make delete-old-libs" after a 1094 "make installworld". 1095 1096 Additionally, the atf-sh binary was made private by moving it into 1097 /usr/libexec/. Already-built shell test programs will keep the 1098 path to the old binary so they will break after "make delete-old" 1099 is run. 1100 1101 If you are using WITH_TESTS=yes (not the default), wipe the object 1102 tree and rebuild from scratch to prevent spurious test failures. 1103 This is only needed once: the misnumbered libraries and misplaced 1104 binaries have been added to OptionalObsoleteFiles.inc so they will 1105 be removed during a clean upgrade. 1106 110720140512: 1108 Clang and llvm have been upgraded to 3.4.1 release. 1109 111020140508: 1111 We bogusly installed src.opts.mk in /usr/share/mk. This file should 1112 be removed to avoid issues in the future (and has been added to 1113 ObsoleteFiles.inc). 1114 111520140505: 1116 /etc/src.conf now affects only builds of the FreeBSD src tree. In the 1117 past, it affected all builds that used the bsd.*.mk files. The old 1118 behavior was a bug, but people may have relied upon it. To get this 1119 behavior back, you can .include /etc/src.conf from /etc/make.conf 1120 (which is still global and isn't changed). This also changes the 1121 behavior of incremental builds inside the tree of individual 1122 directories. Set MAKESYSPATH to ".../share/mk" to do that. 1123 Although this has survived make universe and some upgrade scenarios, 1124 other upgrade scenarios may have broken. At least one form of 1125 temporary breakage was fixed with MAKESYSPATH settings for buildworld 1126 as well... In cases where MAKESYSPATH isn't working with this 1127 setting, you'll need to set it to the full path to your tree. 1128 1129 One side effect of all this cleaning up is that bsd.compiler.mk 1130 is no longer implicitly included by bsd.own.mk. If you wish to 1131 use COMPILER_TYPE, you must now explicitly include bsd.compiler.mk 1132 as well. 1133 113420140430: 1135 The lindev device has been removed since /dev/full has been made a 1136 standard device. __FreeBSD_version has been bumped. 1137 113820140424: 1139 The knob WITHOUT_VI was added to the base system, which controls 1140 building ex(1), vi(1), etc. Older releases of FreeBSD required ex(1) 1141 in order to reorder files share/termcap and didn't build ex(1) as a 1142 build tool, so building/installing with WITH_VI is highly advised for 1143 build hosts for older releases. 1144 1145 This issue has been fixed in stable/9 and stable/10 in r277022 and 1146 r276991, respectively. 1147 114820140418: 1149 The YES_HESIOD knob has been removed. It has been obsolete for 1150 a decade. Please move to using WITH_HESIOD instead or your builds 1151 will silently lack HESIOD. 1152 115320140405: 1154 The uart(4) driver has been changed with respect to its handling 1155 of the low-level console. Previously the uart(4) driver prevented 1156 any process from changing the baudrate or the CLOCAL and HUPCL 1157 control flags. By removing the restrictions, operators can make 1158 changes to the serial console port without having to reboot. 1159 However, when getty(8) is started on the serial device that is 1160 associated with the low-level console, a misconfigured terminal 1161 line in /etc/ttys will now have a real impact. 1162 Before upgrading the kernel, make sure that /etc/ttys has the 1163 serial console device configured as 3wire without baudrate to 1164 preserve the previous behaviour. E.g: 1165 ttyu0 "/usr/libexec/getty 3wire" vt100 on secure 1166 116720140306: 1168 Support for libwrap (TCP wrappers) in rpcbind was disabled by default 1169 to improve performance. To re-enable it, if needed, run rpcbind 1170 with command line option -W. 1171 117220140226: 1173 Switched back to the GPL dtc compiler due to updates in the upstream 1174 dts files not being supported by the BSDL dtc compiler. You will need 1175 to rebuild your kernel toolchain to pick up the new compiler. Core dumps 1176 may result while building dtb files during a kernel build if you fail 1177 to do so. Set WITHOUT_GPL_DTC if you require the BSDL compiler. 1178 117920140216: 1180 Clang and llvm have been upgraded to 3.4 release. 1181 118220140216: 1183 The nve(4) driver has been removed. Please use the nfe(4) driver 1184 for NVIDIA nForce MCP Ethernet adapters instead. 1185 118620140212: 1187 An ABI incompatibility crept into the libc++ 3.4 import in r261283. 1188 This could cause certain C++ applications using shared libraries built 1189 against the previous version of libc++ to crash. The incompatibility 1190 has now been fixed, but any C++ applications or shared libraries built 1191 between r261283 and r261801 should be recompiled. 1192 119320140204: 1194 OpenSSH will now ignore errors caused by kernel lacking of Capsicum 1195 capability mode support. Please note that enabling the feature in 1196 kernel is still highly recommended. 1197 119820140131: 1199 OpenSSH is now built with sandbox support, and will use sandbox as 1200 the default privilege separation method. This requires Capsicum 1201 capability mode support in kernel. 1202 120320140128: 1204 The libelf and libdwarf libraries have been updated to newer 1205 versions from upstream. Shared library version numbers for 1206 these two libraries were bumped. Any ports or binaries 1207 requiring these two libraries should be recompiled. 1208 __FreeBSD_version is bumped to 1100006. 1209 121020140110: 1211 If a Makefile in a tests/ directory was auto-generating a Kyuafile 1212 instead of providing an explicit one, this would prevent such 1213 Makefile from providing its own Kyuafile in the future during 1214 NO_CLEAN builds. This has been fixed in the Makefiles but manual 1215 intervention is needed to clean an objdir if you use NO_CLEAN: 1216 # find /usr/obj -name Kyuafile | xargs rm -f 1217 121820131213: 1219 The behavior of gss_pseudo_random() for the krb5 mechanism 1220 has changed, for applications requesting a longer random string 1221 than produced by the underlying enctype's pseudo-random() function. 1222 In particular, the random string produced from a session key of 1223 enctype aes256-cts-hmac-sha1-96 or aes256-cts-hmac-sha1-96 will 1224 be different at the 17th octet and later, after this change. 1225 The counter used in the PRF+ construction is now encoded as a 1226 big-endian integer in accordance with RFC 4402. 1227 __FreeBSD_version is bumped to 1100004. 1228 122920131108: 1230 The WITHOUT_ATF build knob has been removed and its functionality 1231 has been subsumed into the more generic WITHOUT_TESTS. If you were 1232 using the former to disable the build of the ATF libraries, you 1233 should change your settings to use the latter. 1234 123520131025: 1236 The default version of mtree is nmtree which is obtained from 1237 NetBSD. The output is generally the same, but may vary 1238 slightly. If you found you need identical output adding 1239 "-F freebsd9" to the command line should do the trick. For the 1240 time being, the old mtree is available as fmtree. 1241 124220131014: 1243 libbsdyml has been renamed to libyaml and moved to /usr/lib/private. 1244 This will break ports-mgmt/pkg. Rebuild the port, or upgrade to pkg 1245 1.1.4_8 and verify bsdyml not linked in, before running "make 1246 delete-old-libs": 1247 # make -C /usr/ports/ports-mgmt/pkg build deinstall install clean 1248 or 1249 # pkg install pkg; ldd /usr/local/sbin/pkg | grep bsdyml 1250 125120131010: 1252 The stable/10 branch has been created in subversion from head 1253 revision r256279. 1254 125520131010: 1256 The rc.d/jail script has been updated to support jail(8) 1257 configuration file. The "jail_<jname>_*" rc.conf(5) variables 1258 for per-jail configuration are automatically converted to 1259 /var/run/jail.<jname>.conf before the jail(8) utility is invoked. 1260 This is transparently backward compatible. See below about some 1261 incompatibilities and rc.conf(5) manual page for more details. 1262 1263 These variables are now deprecated in favor of jail(8) configuration 1264 file. One can use "rc.d/jail config <jname>" command to generate 1265 a jail(8) configuration file in /var/run/jail.<jname>.conf without 1266 running the jail(8) utility. The default pathname of the 1267 configuration file is /etc/jail.conf and can be specified by 1268 using $jail_conf or $jail_<jname>_conf variables. 1269 1270 Please note that jail_devfs_ruleset accepts an integer at 1271 this moment. Please consider to rewrite the ruleset name 1272 with an integer. 1273 127420130930: 1275 BIND has been removed from the base system. If all you need 1276 is a local resolver, simply enable and start the local_unbound 1277 service instead. Otherwise, several versions of BIND are 1278 available in the ports tree. The dns/bind99 port is one example. 1279 1280 With this change, nslookup(1) and dig(1) are no longer in the base 1281 system. Users should instead use host(1) and drill(1) which are 1282 in the base system. Alternatively, nslookup and dig can 1283 be obtained by installing the dns/bind-tools port. 1284 128520130916: 1286 With the addition of unbound(8), a new unbound user is now 1287 required during installworld. "mergemaster -p" can be used to 1288 add the user prior to installworld, as documented in the handbook. 1289 129020130911: 1291 OpenSSH is now built with DNSSEC support, and will by default 1292 silently trust signed SSHFP records. This can be controlled with 1293 the VerifyHostKeyDNS client configuration setting. DNSSEC support 1294 can be disabled entirely with the WITHOUT_LDNS option in src.conf. 1295 129620130906: 1297 The GNU Compiler Collection and C++ standard library (libstdc++) 1298 are no longer built by default on platforms where clang is the system 1299 compiler. You can enable them with the WITH_GCC and WITH_GNUCXX 1300 options in src.conf. 1301 130220130905: 1303 The PROCDESC kernel option is now part of the GENERIC kernel 1304 configuration and is required for the rwhod(8) to work. 1305 If you are using custom kernel configuration, you should include 1306 'options PROCDESC'. 1307 130820130905: 1309 The API and ABI related to the Capsicum framework was modified 1310 in backward incompatible way. The userland libraries and programs 1311 have to be recompiled to work with the new kernel. This includes the 1312 following libraries and programs, but the whole buildworld is 1313 advised: libc, libprocstat, dhclient, tcpdump, hastd, hastctl, 1314 kdump, procstat, rwho, rwhod, uniq. 1315 131620130903: 1317 AES-NI intrinsic support has been added to gcc. The AES-NI module 1318 has been updated to use this support. A new gcc is required to build 1319 the aesni module on both i386 and amd64. 1320 132120130821: 1322 The PADLOCK_RNG and RDRAND_RNG kernel options are now devices. 1323 Thus "device padlock_rng" and "device rdrand_rng" should be 1324 used instead of "options PADLOCK_RNG" & "options RDRAND_RNG". 1325 132620130813: 1327 WITH_ICONV has been split into two feature sets. WITH_ICONV now 1328 enables just the iconv* functionality and is now on by default. 1329 WITH_LIBICONV_COMPAT enables the libiconv api and link time 1330 compatibility. Set WITHOUT_ICONV to build the old way. 1331 If you have been using WITH_ICONV before, you will very likely 1332 need to turn on WITH_LIBICONV_COMPAT. 1333 133420130806: 1335 INVARIANTS option now enables DEBUG for code with OpenSolaris and 1336 Illumos origin, including ZFS. If you have INVARIANTS in your 1337 kernel configuration, then there is no need to set DEBUG or ZFS_DEBUG 1338 explicitly. 1339 DEBUG used to enable witness(9) tracking of OpenSolaris (mostly ZFS) 1340 locks if WITNESS option was set. Because that generated a lot of 1341 witness(9) reports and all of them were believed to be false 1342 positives, this is no longer done. New option OPENSOLARIS_WITNESS 1343 can be used to achieve the previous behavior. 1344 134520130806: 1346 Timer values in IPv6 data structures now use time_uptime instead 1347 of time_second. Although this is not a user-visible functional 1348 change, userland utilities which directly use them---ndp(8), 1349 rtadvd(8), and rtsold(8) in the base system---need to be updated 1350 to r253970 or later. 1351 135220130802: 1353 find -delete can now delete the pathnames given as arguments, 1354 instead of only files found below them or if the pathname did 1355 not contain any slashes. Formerly, the following error message 1356 would result: 1357 1358 find: -delete: <path>: relative path potentially not safe 1359 1360 Deleting the pathnames given as arguments can be prevented 1361 without error messages using -mindepth 1 or by changing 1362 directory and passing "." as argument to find. This works in the 1363 old as well as the new version of find. 1364 136520130726: 1366 Behavior of devfs rules path matching has been changed. 1367 Pattern is now always matched against fully qualified devfs 1368 path and slash characters must be explicitly matched by 1369 slashes in pattern (FNM_PATHNAME). Rulesets involving devfs 1370 subdirectories must be reviewed. 1371 137220130716: 1373 The default ARM ABI has changed to the ARM EABI. The old ABI is 1374 incompatible with the ARM EABI and all programs and modules will 1375 need to be rebuilt to work with a new kernel. 1376 1377 To keep using the old ABI ensure the WITHOUT_ARM_EABI knob is set. 1378 1379 NOTE: Support for the old ABI will be removed in the future and 1380 users are advised to upgrade. 1381 138220130709: 1383 pkg_install has been disconnected from the build if you really need it 1384 you should add WITH_PKGTOOLS in your src.conf(5). 1385 138620130709: 1387 Most of network statistics structures were changed to be able 1388 keep 64-bits counters. Thus all tools, that work with networking 1389 statistics, must be rebuilt (netstat(1), bsnmpd(1), etc.) 1390 139120130618: 1392 Fix a bug that allowed a tracing process (e.g. gdb) to write 1393 to a memory-mapped file in the traced process's address space 1394 even if neither the traced process nor the tracing process had 1395 write access to that file. 1396 139720130615: 1398 CVS has been removed from the base system. An exact copy 1399 of the code is available from the devel/cvs port. 1400 140120130613: 1402 Some people report the following error after the switch to bmake: 1403 1404 make: illegal option -- J 1405 usage: make [-BPSXeiknpqrstv] [-C directory] [-D variable] 1406 ... 1407 *** [buildworld] Error code 2 1408 1409 this likely due to an old instance of make in 1410 ${MAKEPATH} (${MAKEOBJDIRPREFIX}${.CURDIR}/make.${MACHINE}) 1411 which src/Makefile will use that blindly, if it exists, so if 1412 you see the above error: 1413 1414 rm -rf `make -V MAKEPATH` 1415 1416 should resolve it. 1417 141820130516: 1419 Use bmake by default. 1420 Whereas before one could choose to build with bmake via 1421 -DWITH_BMAKE one must now use -DWITHOUT_BMAKE to use the old 1422 make. The goal is to remove these knobs for 10-RELEASE. 1423 1424 It is worth noting that bmake (like gmake) treats the command 1425 line as the unit of failure, rather than statements within the 1426 command line. Thus '(cd some/where && dosomething)' is safer 1427 than 'cd some/where; dosomething'. The '()' allows consistent 1428 behavior in parallel build. 1429 143020130429: 1431 Fix a bug that allows NFS clients to issue READDIR on files. 1432 143320130426: 1434 The WITHOUT_IDEA option has been removed because 1435 the IDEA patent expired. 1436 143720130426: 1438 The sysctl which controls TRIM support under ZFS has been renamed 1439 from vfs.zfs.trim_disable -> vfs.zfs.trim.enabled and has been 1440 enabled by default. 1441 144220130425: 1443 The mergemaster command now uses the default MAKEOBJDIRPREFIX 1444 rather than creating it's own in the temporary directory in 1445 order allow access to bootstrapped versions of tools such as 1446 install and mtree. When upgrading from version of FreeBSD where 1447 the install command does not support -l, you will need to 1448 install a new mergemaster command if mergemaster -p is required. 1449 This can be accomplished with the command (cd src/usr.sbin/mergemaster 1450 && make install). 1451 145220130404: 1453 Legacy ATA stack, disabled and replaced by new CAM-based one since 1454 FreeBSD 9.0, completely removed from the sources. Kernel modules 1455 atadisk and atapi*, user-level tools atacontrol and burncd are 1456 removed. Kernel option `options ATA_CAM` is now permanently enabled 1457 and removed. 1458 145920130319: 1460 SOCK_CLOEXEC and SOCK_NONBLOCK flags have been added to socket(2) 1461 and socketpair(2). Software, in particular Kerberos, may 1462 automatically detect and use these during building. The resulting 1463 binaries will not work on older kernels. 1464 146520130308: 1466 CTL_DISABLE has also been added to the sparc64 GENERIC (for further 1467 information, see the respective 20130304 entry). 1468 146920130304: 1470 Recent commits to callout(9) changed the size of struct callout, 1471 so the KBI is probably heavily disturbed. Also, some functions 1472 in callout(9)/sleep(9)/sleepqueue(9)/condvar(9) KPIs were replaced 1473 by macros. Every kernel module using it won't load, so rebuild 1474 is requested. 1475 1476 The ctl device has been re-enabled in GENERIC for i386 and amd64, 1477 but does not initialize by default (because of the new CTL_DISABLE 1478 option) to save memory. To re-enable it, remove the CTL_DISABLE 1479 option from the kernel config file or set kern.cam.ctl.disable=0 1480 in /boot/loader.conf. 1481 148220130301: 1483 The ctl device has been disabled in GENERIC for i386 and amd64. 1484 This was done due to the extra memory being allocated at system 1485 initialisation time by the ctl driver which was only used if 1486 a CAM target device was created. This makes a FreeBSD system 1487 unusable on 128MB or less of RAM. 1488 148920130208: 1490 A new compression method (lz4) has been merged to -HEAD. Please 1491 refer to zpool-features(7) for more information. 1492 1493 Please refer to the "ZFS notes" section of this file for information 1494 on upgrading boot ZFS pools. 1495 149620130129: 1497 A BSD-licensed patch(1) variant has been added and is installed 1498 as bsdpatch, being the GNU version the default patch. 1499 To inverse the logic and use the BSD-licensed one as default, 1500 while having the GNU version installed as gnupatch, rebuild 1501 and install world with the WITH_BSD_PATCH knob set. 1502 150320130121: 1504 Due to the use of the new -l option to install(1) during build 1505 and install, you must take care not to directly set the INSTALL 1506 make variable in your /etc/make.conf, /etc/src.conf, or on the 1507 command line. If you wish to use the -C flag for all installs 1508 you may be able to add INSTALL+=-C to /etc/make.conf or 1509 /etc/src.conf. 1510 151120130118: 1512 The install(1) option -M has changed meaning and now takes an 1513 argument that is a file or path to append logs to. In the 1514 unlikely event that -M was the last option on the command line 1515 and the command line contained at least two files and a target 1516 directory the first file will have logs appended to it. The -M 1517 option served little practical purpose in the last decade so its 1518 use is expected to be extremely rare. 1519 152020121223: 1521 After switching to Clang as the default compiler some users of ZFS 1522 on i386 systems started to experience stack overflow kernel panics. 1523 Please consider using 'options KSTACK_PAGES=4' in such configurations. 1524 152520121222: 1526 GEOM_LABEL now mangles label names read from file system metadata. 1527 Mangling affect labels containing spaces, non-printable characters, 1528 '%' or '"'. Device names in /etc/fstab and other places may need to 1529 be updated. 1530 153120121217: 1532 By default, only the 10 most recent kernel dumps will be saved. To 1533 restore the previous behaviour (no limit on the number of kernel dumps 1534 stored in the dump directory) add the following line to /etc/rc.conf: 1535 1536 savecore_flags="" 1537 153820121201: 1539 With the addition of auditdistd(8), a new auditdistd user is now 1540 required during installworld. "mergemaster -p" can be used to 1541 add the user prior to installworld, as documented in the handbook. 1542 154320121117: 1544 The sin6_scope_id member variable in struct sockaddr_in6 is now 1545 filled by the kernel before passing the structure to the userland via 1546 sysctl or routing socket. This means the KAME-specific embedded scope 1547 id in sin6_addr.s6_addr[2] is always cleared in userland application. 1548 This behavior can be controlled by net.inet6.ip6.deembed_scopeid. 1549 __FreeBSD_version is bumped to 1000025. 1550 155120121105: 1552 On i386 and amd64 systems WITH_CLANG_IS_CC is now the default. 1553 This means that the world and kernel will be compiled with clang 1554 and that clang will be installed as /usr/bin/cc, /usr/bin/c++, 1555 and /usr/bin/cpp. To disable this behavior and revert to building 1556 with gcc, compile with WITHOUT_CLANG_IS_CC. Really old versions 1557 of current may need to bootstrap WITHOUT_CLANG first if the clang 1558 build fails (its compatibility window doesn't extend to the 9 stable 1559 branch point). 1560 156120121102: 1562 The IPFIREWALL_FORWARD kernel option has been removed. Its 1563 functionality now turned on by default. 1564 156520121023: 1566 The ZERO_COPY_SOCKET kernel option has been removed and 1567 split into SOCKET_SEND_COW and SOCKET_RECV_PFLIP. 1568 NB: SOCKET_SEND_COW uses the VM page based copy-on-write 1569 mechanism which is not safe and may result in kernel crashes. 1570 NB: The SOCKET_RECV_PFLIP mechanism is useless as no current 1571 driver supports disposeable external page sized mbuf storage. 1572 Proper replacements for both zero-copy mechanisms are under 1573 consideration and will eventually lead to complete removal 1574 of the two kernel options. 1575 157620121023: 1577 The IPv4 network stack has been converted to network byte 1578 order. The following modules need to be recompiled together 1579 with kernel: carp(4), divert(4), gif(4), siftr(4), gre(4), 1580 pf(4), ipfw(4), ng_ipfw(4), stf(4). 1581 158220121022: 1583 Support for non-MPSAFE filesystems was removed from VFS. The 1584 VFS_VERSION was bumped, all filesystem modules shall be 1585 recompiled. 1586 158720121018: 1588 All the non-MPSAFE filesystems have been disconnected from 1589 the build. The full list includes: codafs, hpfs, ntfs, nwfs, 1590 portalfs, smbfs, xfs. 1591 159220121016: 1593 The interface cloning API and ABI has changed. The following 1594 modules need to be recompiled together with kernel: 1595 ipfw(4), pfsync(4), pflog(4), usb(4), wlan(4), stf(4), 1596 vlan(4), disc(4), edsc(4), if_bridge(4), gif(4), tap(4), 1597 faith(4), epair(4), enc(4), tun(4), if_lagg(4), gre(4). 1598 159920121015: 1600 The sdhci driver was split in two parts: sdhci (generic SD Host 1601 Controller logic) and sdhci_pci (actual hardware driver). 1602 No kernel config modifications are required, but if you 1603 load sdhc as a module you must switch to sdhci_pci instead. 1604 160520121014: 1606 Import the FUSE kernel and userland support into base system. 1607 160820121013: 1609 The GNU sort(1) program has been removed since the BSD-licensed 1610 sort(1) has been the default for quite some time and no serious 1611 problems have been reported. The corresponding WITH_GNU_SORT 1612 knob has also gone. 1613 161420121006: 1615 The pfil(9) API/ABI for AF_INET family has been changed. Packet 1616 filtering modules: pf(4), ipfw(4), ipfilter(4) need to be recompiled 1617 with new kernel. 1618 161920121001: 1620 The net80211(4) ABI has been changed to allow for improved driver 1621 PS-POLL and power-save support. All wireless drivers need to be 1622 recompiled to work with the new kernel. 1623 162420120913: 1625 The random(4) support for the VIA hardware random number 1626 generator (`PADLOCK') is no longer enabled unconditionally. 1627 Add the padlock_rng device in the custom kernel config if 1628 needed. The GENERIC kernels on i386 and amd64 do include the 1629 device, so the change only affects the custom kernel 1630 configurations. 1631 163220120908: 1633 The pf(4) packet filter ABI has been changed. pfctl(8) and 1634 snmp_pf module need to be recompiled to work with new kernel. 1635 163620120828: 1637 A new ZFS feature flag "com.delphix:empty_bpobj" has been merged 1638 to -HEAD. Pools that have empty_bpobj in active state can not be 1639 imported read-write with ZFS implementations that do not support 1640 this feature. For more information read the zpool-features(5) 1641 manual page. 1642 164320120727: 1644 The sparc64 ZFS loader has been changed to no longer try to auto- 1645 detect ZFS providers based on diskN aliases but now requires these 1646 to be explicitly listed in the OFW boot-device environment variable. 1647 164820120712: 1649 The OpenSSL has been upgraded to 1.0.1c. Any binaries requiring 1650 libcrypto.so.6 or libssl.so.6 must be recompiled. Also, there are 1651 configuration changes. Make sure to merge /etc/ssl/openssl.cnf. 1652 165320120712: 1654 The following sysctls and tunables have been renamed for consistency 1655 with other variables: 1656 kern.cam.da.da_send_ordered -> kern.cam.da.send_ordered 1657 kern.cam.ada.ada_send_ordered -> kern.cam.ada.send_ordered 1658 165920120628: 1660 The sort utility has been replaced with BSD sort. For now, GNU sort 1661 is also available as "gnusort" or the default can be set back to 1662 GNU sort by setting WITH_GNU_SORT. In this case, BSD sort will be 1663 installed as "bsdsort". 1664 166520120611: 1666 A new version of ZFS (pool version 5000) has been merged to -HEAD. 1667 Starting with this version the old system of ZFS pool versioning 1668 is superseded by "feature flags". This concept enables forward 1669 compatibility against certain future changes in functionality of ZFS 1670 pools. The first read-only compatible "feature flag" for ZFS pools 1671 is named "com.delphix:async_destroy". For more information 1672 read the new zpool-features(5) manual page. 1673 Please refer to the "ZFS notes" section of this file for information 1674 on upgrading boot ZFS pools. 1675 167620120417: 1677 The malloc(3) implementation embedded in libc now uses sources imported 1678 as contrib/jemalloc. The most disruptive API change is to 1679 /etc/malloc.conf. If your system has an old-style /etc/malloc.conf, 1680 delete it prior to installworld, and optionally re-create it using the 1681 new format after rebooting. See malloc.conf(5) for details 1682 (specifically the TUNING section and the "opt.*" entries in the MALLCTL 1683 NAMESPACE section). 1684 168520120328: 1686 Big-endian MIPS TARGET_ARCH values no longer end in "eb". mips64eb 1687 is now spelled mips64. mipsn32eb is now spelled mipsn32. mipseb is 1688 now spelled mips. This is to aid compatibility with third-party 1689 software that expects this naming scheme in uname(3). Little-endian 1690 settings are unchanged. If you are updating a big-endian mips64 machine 1691 from before this change, you may need to set MACHINE_ARCH=mips64 in 1692 your environment before the new build system will recognize your machine. 1693 169420120306: 1695 Disable by default the option VFS_ALLOW_NONMPSAFE for all supported 1696 platforms. 1697 169820120229: 1699 Now unix domain sockets behave "as expected" on nullfs(5). Previously 1700 nullfs(5) did not pass through all behaviours to the underlying layer, 1701 as a result if we bound to a socket on the lower layer we could connect 1702 only to the lower path; if we bound to the upper layer we could connect 1703 only to the upper path. The new behavior is one can connect to both the 1704 lower and the upper paths regardless what layer path one binds to. 1705 170620120211: 1707 The getifaddrs upgrade path broken with 20111215 has been restored. 1708 If you have upgraded in between 20111215 and 20120209 you need to 1709 recompile libc again with your kernel. You still need to recompile 1710 world to be able to configure CARP but this restriction already 1711 comes from 20111215. 1712 171320120114: 1714 The set_rcvar() function has been removed from /etc/rc.subr. All 1715 base and ports rc.d scripts have been updated, so if you have a 1716 port installed with a script in /usr/local/etc/rc.d you can either 1717 hand-edit the rcvar= line, or reinstall the port. 1718 1719 An easy way to handle the mass-update of /etc/rc.d: 1720 rm /etc/rc.d/* && mergemaster -i 1721 172220120109: 1723 panic(9) now stops other CPUs in the SMP systems, disables interrupts 1724 on the current CPU and prevents other threads from running. 1725 This behavior can be reverted using the kern.stop_scheduler_on_panic 1726 tunable/sysctl. 1727 The new behavior can be incompatible with kern.sync_on_panic. 1728 172920111215: 1730 The carp(4) facility has been changed significantly. Configuration 1731 of the CARP protocol via ifconfig(8) has changed, as well as format 1732 of CARP events submitted to devd(8) has changed. See manual pages 1733 for more information. The arpbalance feature of carp(4) is currently 1734 not supported anymore. 1735 1736 Size of struct in_aliasreq, struct in6_aliasreq has changed. User 1737 utilities using SIOCAIFADDR, SIOCAIFADDR_IN6, e.g. ifconfig(8), 1738 need to be recompiled. 1739 174020111122: 1741 The acpi_wmi(4) status device /dev/wmistat has been renamed to 1742 /dev/wmistat0. 1743 174420111108: 1745 The option VFS_ALLOW_NONMPSAFE option has been added in order to 1746 explicitely support non-MPSAFE filesystems. 1747 It is on by default for all supported platform at this present 1748 time. 1749 175020111101: 1751 The broken amd(4) driver has been replaced with esp(4) in the amd64, 1752 i386 and pc98 GENERIC kernel configuration files. 1753 175420110930: 1755 sysinstall has been removed 1756 175720110923: 1758 The stable/9 branch created in subversion. This corresponds to the 1759 RELENG_9 branch in CVS. 1760 1761COMMON ITEMS: 1762 1763 General Notes 1764 ------------- 1765 Avoid using make -j when upgrading. While generally safe, there are 1766 sometimes problems using -j to upgrade. If your upgrade fails with 1767 -j, please try again without -j. From time to time in the past there 1768 have been problems using -j with buildworld and/or installworld. This 1769 is especially true when upgrading between "distant" versions (eg one 1770 that cross a major release boundary or several minor releases, or when 1771 several months have passed on the -current branch). 1772 1773 Sometimes, obscure build problems are the result of environment 1774 poisoning. This can happen because the make utility reads its 1775 environment when searching for values for global variables. To run 1776 your build attempts in an "environmental clean room", prefix all make 1777 commands with 'env -i '. See the env(1) manual page for more details. 1778 1779 When upgrading from one major version to another it is generally best to 1780 upgrade to the latest code in the currently installed branch first, then 1781 do an upgrade to the new branch. This is the best-tested upgrade path, 1782 and has the highest probability of being successful. Please try this 1783 approach if you encounter problems with a major version upgrade. Since 1784 the stable 4.x branch point, one has generally been able to upgade from 1785 anywhere in the most recent stable branch to head / current (or even the 1786 last couple of stable branches). See the top of this file when there's 1787 an exception. 1788 1789 When upgrading a live system, having a root shell around before 1790 installing anything can help undo problems. Not having a root shell 1791 around can lead to problems if pam has changed too much from your 1792 starting point to allow continued authentication after the upgrade. 1793 1794 This file should be read as a log of events. When a later event changes 1795 information of a prior event, the prior event should not be deleted. 1796 Instead, a pointer to the entry with the new information should be 1797 placed in the old entry. Readers of this file should also sanity check 1798 older entries before relying on them blindly. Authors of new entries 1799 should write them with this in mind. 1800 1801 ZFS notes 1802 --------- 1803 When upgrading the boot ZFS pool to a new version, always follow 1804 these two steps: 1805 1806 1.) recompile and reinstall the ZFS boot loader and boot block 1807 (this is part of "make buildworld" and "make installworld") 1808 1809 2.) update the ZFS boot block on your boot drive 1810 1811 The following example updates the ZFS boot block on the first 1812 partition (freebsd-boot) of a GPT partitioned drive ada0: 1813 "gpart bootcode -p /boot/gptzfsboot -i 1 ada0" 1814 1815 Non-boot pools do not need these updates. 1816 1817 To build a kernel 1818 ----------------- 1819 If you are updating from a prior version of FreeBSD (even one just 1820 a few days old), you should follow this procedure. It is the most 1821 failsafe as it uses a /usr/obj tree with a fresh mini-buildworld, 1822 1823 make kernel-toolchain 1824 make -DALWAYS_CHECK_MAKE buildkernel KERNCONF=YOUR_KERNEL_HERE 1825 make -DALWAYS_CHECK_MAKE installkernel KERNCONF=YOUR_KERNEL_HERE 1826 1827 To test a kernel once 1828 --------------------- 1829 If you just want to boot a kernel once (because you are not sure 1830 if it works, or if you want to boot a known bad kernel to provide 1831 debugging information) run 1832 make installkernel KERNCONF=YOUR_KERNEL_HERE KODIR=/boot/testkernel 1833 nextboot -k testkernel 1834 1835 To just build a kernel when you know that it won't mess you up 1836 -------------------------------------------------------------- 1837 This assumes you are already running a CURRENT system. Replace 1838 ${arch} with the architecture of your machine (e.g. "i386", 1839 "arm", "amd64", "ia64", "pc98", "sparc64", "powerpc", "mips", etc). 1840 1841 cd src/sys/${arch}/conf 1842 config KERNEL_NAME_HERE 1843 cd ../compile/KERNEL_NAME_HERE 1844 make depend 1845 make 1846 make install 1847 1848 If this fails, go to the "To build a kernel" section. 1849 1850 To rebuild everything and install it on the current system. 1851 ----------------------------------------------------------- 1852 # Note: sometimes if you are running current you gotta do more than 1853 # is listed here if you are upgrading from a really old current. 1854 1855 <make sure you have good level 0 dumps> 1856 make buildworld 1857 make kernel KERNCONF=YOUR_KERNEL_HERE 1858 [1] 1859 <reboot in single user> [3] 1860 mergemaster -Fp [5] 1861 make installworld 1862 mergemaster -Fi [4] 1863 make delete-old [6] 1864 <reboot> 1865 1866 To cross-install current onto a separate partition 1867 -------------------------------------------------- 1868 # In this approach we use a separate partition to hold 1869 # current's root, 'usr', and 'var' directories. A partition 1870 # holding "/", "/usr" and "/var" should be about 2GB in 1871 # size. 1872 1873 <make sure you have good level 0 dumps> 1874 <boot into -stable> 1875 make buildworld 1876 make buildkernel KERNCONF=YOUR_KERNEL_HERE 1877 <maybe newfs current's root partition> 1878 <mount current's root partition on directory ${CURRENT_ROOT}> 1879 make installworld DESTDIR=${CURRENT_ROOT} -DDB_FROM_SRC 1880 make distribution DESTDIR=${CURRENT_ROOT} # if newfs'd 1881 make installkernel KERNCONF=YOUR_KERNEL_HERE DESTDIR=${CURRENT_ROOT} 1882 cp /etc/fstab ${CURRENT_ROOT}/etc/fstab # if newfs'd 1883 <edit ${CURRENT_ROOT}/etc/fstab to mount "/" from the correct partition> 1884 <reboot into current> 1885 <do a "native" rebuild/install as described in the previous section> 1886 <maybe install compatibility libraries from ports/misc/compat*> 1887 <reboot> 1888 1889 1890 To upgrade in-place from stable to current 1891 ---------------------------------------------- 1892 <make sure you have good level 0 dumps> 1893 make buildworld [9] 1894 make kernel KERNCONF=YOUR_KERNEL_HERE [8] 1895 [1] 1896 <reboot in single user> [3] 1897 mergemaster -Fp [5] 1898 make installworld 1899 mergemaster -Fi [4] 1900 make delete-old [6] 1901 <reboot> 1902 1903 Make sure that you've read the UPDATING file to understand the 1904 tweaks to various things you need. At this point in the life 1905 cycle of current, things change often and you are on your own 1906 to cope. The defaults can also change, so please read ALL of 1907 the UPDATING entries. 1908 1909 Also, if you are tracking -current, you must be subscribed to 1910 freebsd-current@freebsd.org. Make sure that before you update 1911 your sources that you have read and understood all the recent 1912 messages there. If in doubt, please track -stable which has 1913 much fewer pitfalls. 1914 1915 [1] If you have third party modules, such as vmware, you 1916 should disable them at this point so they don't crash your 1917 system on reboot. 1918 1919 [3] From the bootblocks, boot -s, and then do 1920 fsck -p 1921 mount -u / 1922 mount -a 1923 cd src 1924 adjkerntz -i # if CMOS is wall time 1925 Also, when doing a major release upgrade, it is required that 1926 you boot into single user mode to do the installworld. 1927 1928 [4] Note: This step is non-optional. Failure to do this step 1929 can result in a significant reduction in the functionality of the 1930 system. Attempting to do it by hand is not recommended and those 1931 that pursue this avenue should read this file carefully, as well 1932 as the archives of freebsd-current and freebsd-hackers mailing lists 1933 for potential gotchas. The -U option is also useful to consider. 1934 See mergemaster(8) for more information. 1935 1936 [5] Usually this step is a noop. However, from time to time 1937 you may need to do this if you get unknown user in the following 1938 step. It never hurts to do it all the time. You may need to 1939 install a new mergemaster (cd src/usr.sbin/mergemaster && make 1940 install) after the buildworld before this step if you last updated 1941 from current before 20130425 or from -stable before 20130430. 1942 1943 [6] This only deletes old files and directories. Old libraries 1944 can be deleted by "make delete-old-libs", but you have to make 1945 sure that no program is using those libraries anymore. 1946 1947 [8] In order to have a kernel that can run the 4.x binaries needed to 1948 do an installworld, you must include the COMPAT_FREEBSD4 option in 1949 your kernel. Failure to do so may leave you with a system that is 1950 hard to boot to recover. A similar kernel option COMPAT_FREEBSD5 is 1951 required to run the 5.x binaries on more recent kernels. And so on 1952 for COMPAT_FREEBSD6 and COMPAT_FREEBSD7. 1953 1954 Make sure that you merge any new devices from GENERIC since the 1955 last time you updated your kernel config file. 1956 1957 [9] When checking out sources, you must include the -P flag to have 1958 cvs prune empty directories. 1959 1960 If CPUTYPE is defined in your /etc/make.conf, make sure to use the 1961 "?=" instead of the "=" assignment operator, so that buildworld can 1962 override the CPUTYPE if it needs to. 1963 1964 MAKEOBJDIRPREFIX must be defined in an environment variable, and 1965 not on the command line, or in /etc/make.conf. buildworld will 1966 warn if it is improperly defined. 1967FORMAT: 1968 1969This file contains a list, in reverse chronological order, of major 1970breakages in tracking -current. It is not guaranteed to be a complete 1971list of such breakages, and only contains entries since September 23, 2011. 1972If you need to see UPDATING entries from before that date, you will need 1973to fetch an UPDATING file from an older FreeBSD release. 1974 1975Copyright information: 1976 1977Copyright 1998-2009 M.
