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/current-stable.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 5420171102: 55 Building in a FreeBSD src checkout will automatically create object 56 directories now rather than store files in the current directory if 57 'make obj' was not ran. Calling 'make obj' is no longer necesarry. 58 This feature can be disabled by setting WITHOUT_AUTO_OBJ=yes in 59 /etc/src-env.conf (not /etc/src.conf), or passing the option in the 60 environment. 61 6220171101: 63 The default MAKEOBJDIR has changed from /usr/obj/<srcdir> for native 64 builds, and /usr/obj/<arch>/<srcdir> for cross-builds, to a unified 65 /usr/obj/<srcdir>/<arch>. This behavior can be changed to the old 66 format by setting WITHOUT_UNIFIED_OBJDIR=yes in /etc/src-env.conf, 67 the environment, or with -DWITHOUT_UNIFIED_OBJDIR when building. 68 The UNIFIED_OBJDIR option is a transitional feature that will be 69 removed for 12.0 release; please migrate to the new format for any 70 tools by looking up the OBJDIR used by 'make -V .OBJDIR' means rather 71 than hardcoding paths. 72 7320171028: 74 The native-xtools target no longer installs the files by default to the 75 OBJDIR. Use the native-xtools-install target with a DESTDIR to install 76 to ${DESTDIR}/${NXTP} where NXTP defaults to /nxb-bin. 77 7820171021: 79 As part of the boot loader infrastructure cleanup, LOADER_*_SUPPORT 80 options are changing from controlling the build if defined / undefined 81 to controlling the build with explicit 'yes' or 'no' values. They will 82 shift to WITH/WITHOUT options to match other options in the system. 83 8420171010: 85 libstand has turned into a private library for sys/boot use only. 86 It is no longer supported as a public interface outside of sys/boot. 87 8820171005: 89 The arm port has split armv6 into armv6 and armv7. armv7 is now 90 a valid TARGET_ARCH/MACHINE_ARCH setting. If you have an armv7 system 91 and are running a kernel from before r324363, you will need to add 92 MACHINE_ARCH=armv7 to 'make buildworld' to do a native build. 93 9420171003: 95 When building multiple kernels using KERNCONF, non-existent KERNCONF 96 files will produce an error and buildkernel will fail. Previously 97 missing KERNCONF files silently failed giving no indication as to 98 why, only to subsequently discover during installkernel that the 99 desired kernel was never built in the first place. 100 10120170912: 102 The default serial number format for CTL LUNs has changed. This will 103 affect users who use /dev/diskid/* device nodes, or whose FibreChannel 104 or iSCSI clients care about their LUNs' serial numbers. Users who 105 require serial number stability should hardcode serial numbers in 106 /etc/ctl.conf . 107 10820170912: 109 For 32-bit arm compiled for hard-float support, soft-floating point 110 binaries now always get their shared libraries from 111 LD_SOFT_LIBRARY_PATH (in the past, this was only used if 112 /usr/libsoft also existed). Only users with a hard-float ld.so, but 113 soft-float everything else should be affected. 114 11520170826: 116 The geli password typed at boot is now hidden. To restore the previous 117 behavior, see geli(8) for configuration options. 118 11920170825: 120 Move PMTUD blackhole counters to TCPSTATS and remove them from bare 121 sysctl values. Minor nit, but requires a rebuild of both world/kernel 122 to complete. 123 12420170814: 125 "make check" behavior (made in ^/head@r295380) has been changed to 126 execute from a limited sandbox, as opposed to executing from 127 ${TESTSDIR}. 128 129 Behavioral changes: 130 - The "beforecheck" and "aftercheck" targets are now specified. 131 - ${CHECKDIR} (added in commit noted above) has been removed. 132 - Legacy behavior can be enabled by setting 133 WITHOUT_MAKE_CHECK_USE_SANDBOX in src.conf(5) or the environment. 134 135 If the limited sandbox mode is enabled, "make check" will execute 136 "make distribution", then install, execute the tests, and clean up the 137 sandbox if successful. 138 139 The "make distribution" and "make install" targets are typically run as 140 root to set appropriate permissions and ownership at installation time. 141 The end-user should set "WITH_INSTALL_AS_USER" in src.conf(5) or the 142 environment if executing "make check" with limited sandbox mode using 143 an unprivileged user. 144 14520170808: 146 Since the switch to GPT disk labels, fsck for UFS/FFS has been 147 unable to automatically find alternate superblocks. As of r322297, 148 the information needed to find alternate superblocks has been 149 moved to the end of the area reserved for the boot block. 150 Filesystems created with a newfs of this vintage or later 151 will create the recovery information. If you have a filesystem 152 created prior to this change and wish to have a recovery block 153 created for your filesystem, you can do so by running fsck in 154 forground mode (i.e., do not use the -p or -y options). As it 155 starts, fsck will ask ``SAVE DATA TO FIND ALTERNATE SUPERBLOCKS'' 156 to which you should answer yes. 157 15820170728: 159 As of r321665, an NFSv4 server configuration that services 160 Kerberos mounts or clients that do not support the uid/gid in 161 owner/owner_group string capability, must explicitly enable 162 the nfsuserd daemon by adding nfsuserd_enable="YES" to the 163 machine's /etc/rc.conf file. 164 16520170722: 166 Clang, llvm, lldb, compiler-rt and libc++ have been upgraded to 5.0.0. 167 Please see the 20141231 entry below for information about prerequisites 168 and upgrading, if you are not already using clang 3.5.0 or higher. 169 17020170701: 171 WITHOUT_RCMDS is now the default. Set WITH_RCMDS if you need the 172 r-commands (rlogin, rsh, etc.) to be built with the base system. 173 17420170625: 175 The FreeBSD/powerpc platform now uses a 64-bit type for time_t. This is 176 a very major ABI incompatible change, so users of FreeBSD/powerpc must 177 be careful when performing source upgrades. It is best to run 178 'make installworld' from an alternate root system, either a live 179 CD/memory stick, or a temporary root partition. Additionally, all ports 180 must be recompiled. powerpc64 is largely unaffected, except in the case 181 of 32-bit compatibility. All 32-bit binaries will be affected. 182 18320170623: 184 Forward compatibility for the "ino64" project have been committed. This 185 will allow most new binaries to run on older kernels in a limited 186 fashion. This prevents many of the common foot-shooting actions in the 187 upgrade as well as the limited ability to roll back the kernel across 188 the ino64 upgrade. Complicated use cases may not work properly, though 189 enough simpler ones work to allow recovery in most situations. 190 19120170620: 192 Switch back to the BSDL dtc (Device Tree Compiler). Set WITH_GPL_DTC 193 if you require the GPL compiler. 194 19520170618: 196 The internal ABI used for communication between the NFS kernel modules 197 was changed by r320085, so __FreeBSD_version was bumped to 198 ensure all the NFS related modules are updated together. 199 20020170617: 201 The ABI of struct event was changed by extending the data 202 member to 64bit and adding ext fields. For upgrade, same 203 precautions as for the entry 20170523 "ino64" must be 204 followed. 205 20620170531: 207 The GNU roff toolchain has been removed from base. To render manpages 208 which are not supported by mandoc(1), man(1) can fallback on GNU roff 209 from ports (and recommends to install it). 210 To render roff(7) documents, consider using GNU roff from ports or the 211 heirloom doctools roff toolchain from ports via pkg install groff or 212 via pkg install heirloom-doctools. 213 21420170524: 215 The ath(4) and ath_hal(4) modules now build piecemeal to allow for 216 smaller runtime footprint builds. This is useful for embedded systems 217 which only require one chipset support. 218 219 If you load it as a module, make sure this is in /boot/loader.conf: 220 221 if_ath_load="YES" 222 223 This will load the HAL, all chip/RF backends and if_ath_pci. 224 If you have if_ath_pci in /boot/loader.conf, ensure it is after 225 if_ath or it will not load any HAL chipset support. 226 227 If you want to selectively load things (eg on ye cheape ARM/MIPS 228 platforms where RAM is at a premium) you should: 229 230 * load ath_hal 231 * load the chip modules in question 232 * load ath_rate, ath_dfs 233 * load ath_main 234 * load if_ath_pci and/or if_ath_ahb depending upon your particular 235 bus bind type - this is where probe/attach is done. 236 237 For further comments/feedback, poke adrian@ . 238 23920170523: 240 The "ino64" 64-bit inode project has been committed, which extends 241 a number of types to 64 bits. Upgrading in place requires care and 242 adherence to the documented upgrade procedure. 243 244 If using a custom kernel configuration ensure that the 245 COMPAT_FREEBSD11 option is included (as during the upgrade the 246 system will be running the ino64 kernel with the existing world). 247 248 For the safest in-place upgrade begin by removing previous build 249 artifacts via "rm -rf /usr/obj/*". Then, carefully follow the 250 full procedure documented below under the heading "To rebuild 251 everything and install it on the current system." Specifically, 252 a reboot is required after installing the new kernel before 253 installing world. 254 25520170424: 256 The NATM framework including the en(4), fatm(4), hatm(4), and 257 patm(4) devices has been removed. Consumers should plan a 258 migration before the end-of-life date for FreeBSD 11. 259 26020170420: 261 GNU diff has been replaced by a BSD licensed diff. Some features of GNU 262 diff has not been implemented, if those are needed a newer version of 263 GNU diff is available via the diffutils package under the gdiff name. 264 26520170413: 266 As of r316810 for ipfilter, keep frags is no longer assumed when 267 keep state is specified in a rule. r316810 aligns ipfilter with 268 documentation in man pages separating keep frags from keep state. 269 This allows keep state to be specified without forcing keep frags 270 and allows keep frags to be specified independently of keep state. 271 To maintain previous behaviour, also specify keep frags with 272 keep state (as documented in ipf.conf.5). 273 27420170407: 275 arm64 builds now use the base system LLD 4.0.0 linker by default, 276 instead of requiring that the aarch64-binutils port or package be 277 installed. To continue using aarch64-binutils, set 278 CROSS_BINUTILS_PREFIX=/usr/local/aarch64-freebsd/bin . 279 28020170405: 281 The UDP optimization in entry 20160818 that added the sysctl 282 net.inet.udp.require_l2_bcast has been reverted. L2 broadcast 283 packets will no longer be treated as L3 broadcast packets. 284 28520170331: 286 Binds and sends to the loopback addresses, IPv6 and IPv4, will now 287 use any explicitly assigned loopback address available in the jail 288 instead of using the first assigned address of the jail. 289 29020170329: 291 The ctl.ko module no longer implements the iSCSI target frontend: 292 cfiscsi.ko does instead. 293 294 If building cfiscsi.ko as a kernel module, the module can be loaded 295 via one of the following methods: 296 - `cfiscsi_load="YES"` in loader.conf(5). 297 - Add `cfiscsi` to `$kld_list` in rc.conf(5). 298 - ctladm(8)/ctld(8), when compiled with iSCSI support 299 (`WITH_ISCSI=yes` in src.conf(5)) 300 301 Please see cfiscsi(4) for more details. 302 30320170316: 304 The mmcsd.ko module now additionally depends on geom_flashmap.ko. 305 Also, mmc.ko and mmcsd.ko need to be a matching pair built from the 306 same source (previously, the dependency of mmcsd.ko on mmc.ko was 307 missing, but mmcsd.ko now will refuse to load if it is incompatible 308 with mmc.ko). 309 31020170315: 311 The syntax of ipfw(8) named states was changed to avoid ambiguity. 312 If you have used named states in the firewall rules, you need to modify 313 them after installworld and before rebooting. Now named states must 314 be prefixed with colon. 315 31620170311: 317 The old drm (sys/dev/drm/) drivers for i915 and radeon have been 318 removed as the userland we provide cannot use them. The KMS version 319 (sys/dev/drm2) supports the same hardware. 320 32120170302: 322 Clang, llvm, lldb, compiler-rt and libc++ have been upgraded to 4.0.0. 323 Please see the 20141231 entry below for information about prerequisites 324 and upgrading, if you are not already using clang 3.5.0 or higher. 325 32620170221: 327 The code that provides support for ZFS .zfs/ directory functionality 328 has been reimplemented. It's not possible now to create a snapshot 329 by mkdir under .zfs/snapshot/. That should be the only user visible 330 change. 331 33220170216: 333 EISA bus support has been removed. The WITH_EISA option is no longer 334 valid. 335 33620170215: 337 MCA bus support has been removed. 338 33920170127: 340 The WITH_LLD_AS_LD / WITHOUT_LLD_AS_LD build knobs have been renamed 341 WITH_LLD_IS_LD / WITHOUT_LLD_IS_LD, for consistency with CLANG_IS_CC. 342 34320170112: 344 The EM_MULTIQUEUE kernel configuration option is deprecated now that 345 the em(4) driver conforms to iflib specifications. 346 34720170109: 348 The igb(4), em(4) and lem(4) ethernet drivers are now implemented via 349 IFLIB. If you have a custom kernel configuration that excludes em(4) 350 but you use igb(4), you need to re-add em(4) to your custom configuration. 351 35220161217: 353 Clang, llvm, lldb, compiler-rt and libc++ have been upgraded to 3.9.1. 354 Please see the 20141231 entry below for information about prerequisites 355 and upgrading, if you are not already using clang 3.5.0 or higher. 356 35720161124: 358 Clang, llvm, lldb, compiler-rt and libc++ have been upgraded to 3.9.0. 359 Please see the 20141231 entry below for information about prerequisites 360 and upgrading, if you are not already using clang 3.5.0 or higher. 361 36220161119: 363 The layout of the pmap structure has changed for powerpc to put the pmap 364 statistics at the front for all CPU variations. libkvm(3) and all tools 365 that link against it need to be recompiled. 366 36720161030: 368 isl(4) and cyapa(4) drivers now require a new driver, 369 chromebook_platform(4), to work properly on Chromebook-class hardware. 370 On other types of hardware the drivers may need to be configured using 371 device hints. Please see the corresponding manual pages for details. 372 37320161017: 374 The urtwn(4) driver was merged into rtwn(4) and now consists of 375 rtwn(4) main module + rtwn_usb(4) and rtwn_pci(4) bus-specific 376 parts. 377 Also, firmware for RTL8188CE was renamed due to possible name 378 conflict (rtwnrtl8192cU(B) -> rtwnrtl8192cE(B)) 379 38020161015: 381 GNU rcs has been removed from base. It is available as packages: 382 - rcs: Latest GPLv3 GNU rcs version. 383 - rcs57: Copy of the latest version of GNU rcs (GPLv2) before it was 384 removed from base. 385 38620161008: 387 Use of the cc_cdg, cc_chd, cc_hd, or cc_vegas congestion control 388 modules now requires that the kernel configuration contain the 389 TCP_HHOOK option. (This option is included in the GENERIC kernel.) 390 39120161003: 392 The WITHOUT_ELFCOPY_AS_OBJCOPY src.conf(5) knob has been retired. 393 ELF Tool Chain's elfcopy is always installed as /usr/bin/objcopy. 394 39520160924: 396 Relocatable object files with the extension of .So have been renamed 397 to use an extension of .pico instead. The purpose of this change is 398 to avoid a name clash with shared libraries on case-insensitive file 399 systems. On those file systems, foo.So is the same file as foo.so. 400 40120160918: 402 GNU rcs has been turned off by default. It can (temporarily) be built 403 again by adding WITH_RCS knob in src.conf. 404 Otherwise, GNU rcs is available from packages: 405 - rcs: Latest GPLv3 GNU rcs version. 406 - rcs57: Copy of the latest version of GNU rcs (GPLv2) from base. 407 40820160918: 409 The backup_uses_rcs functionality has been removed from rc.subr. 410 41120160908: 412 The queue(3) debugging macro, QUEUE_MACRO_DEBUG, has been split into 413 two separate components, QUEUE_MACRO_DEBUG_TRACE and 414 QUEUE_MACRO_DEBUG_TRASH. Define both for the original 415 QUEUE_MACRO_DEBUG behavior. 416 41720160824: 418 r304787 changed some ioctl interfaces between the iSCSI userspace 419 programs and the kernel. ctladm, ctld, iscsictl, and iscsid must be 420 rebuilt to work with new kernels. __FreeBSD_version has been bumped 421 to 1200005. 422 42320160818: 424 The UDP receive code has been updated to only treat incoming UDP 425 packets that were addressed to an L2 broadcast address as L3 426 broadcast packets. It is not expected that this will affect any 427 standards-conforming UDP application. The new behaviour can be 428 disabled by setting the sysctl net.inet.udp.require_l2_bcast to 429 0. 430 43120160818: 432 Remove the openbsd_poll system call. 433 __FreeBSD_version has been bumped because of this. 434 43520160622: 436 The libc stub for the pipe(2) system call has been replaced with 437 a wrapper that calls the pipe2(2) system call and the pipe(2) 438 system call is now only implemented by the kernels that include 439 "options COMPAT_FREEBSD10" in their config file (this is the 440 default). Users should ensure that this option is enabled in 441 their kernel or upgrade userspace to r302092 before upgrading their 442 kernel. 443 44420160527: 445 CAM will now strip leading spaces from SCSI disks' serial numbers. 446 This will affect users who create UFS filesystems on SCSI disks using 447 those disk's diskid device nodes. For example, if /etc/fstab 448 previously contained a line like 449 "/dev/diskid/DISK-%20%20%20%20%20%20%20ABCDEFG0123456", you should 450 change it to "/dev/diskid/DISK-ABCDEFG0123456". Users of geom 451 transforms like gmirror may also be affected. ZFS users should 452 generally be fine. 453 45420160523: 455 The bitstring(3) API has been updated with new functionality and 456 improved performance. But it is binary-incompatible with the old API. 457 Objects built with the new headers may not be linked against objects 458 built with the old headers. 459 46020160520: 461 The brk and sbrk functions have been removed from libc on arm64. 462 Binutils from ports has been updated to not link to these 463 functions and should be updated to the latest version before 464 installing a new libc. 465 46620160517: 467 The armv6 port now defaults to hard float ABI. Limited support 468 for running both hardfloat and soft float on the same system 469 is available using the libraries installed with -DWITH_LIBSOFT. 470 This has only been tested as an upgrade path for installworld 471 and packages may fail or need manual intervention to run. New 472 packages will be needed. 473 474 To update an existing self-hosted armv6hf system, you must add 475 TARGET_ARCH=armv6 on the make command line for both the build 476 and the install steps. 477 47820160510: 479 Kernel modules compiled outside of a kernel build now default to 480 installing to /boot/modules instead of /boot/kernel. Many kernel 481 modules built this way (such as those in ports) already overrode 482 KMODDIR explicitly to install into /boot/modules. However, 483 manually building and installing a module from /sys/modules will 484 now install to /boot/modules instead of /boot/kernel. 485 48620160414: 487 The CAM I/O scheduler has been committed to the kernel. There should be 488 no user visible impact. This does enable NCQ Trim on ada SSDs. While the 489 list of known rogues that claim support for this but actually corrupt 490 data is believed to be complete, be on the lookout for data 491 corruption. The known rogue list is believed to be complete: 492 493 o Crucial MX100, M550 drives with MU01 firmware. 494 o Micron M510 and M550 drives with MU01 firmware. 495 o Micron M500 prior to MU07 firmware 496 o Samsung 830, 840, and 850 all firmwares 497 o FCCT M500 all firmwares 498 499 Crucial has firmware http://www.crucial.com/usa/en/support-ssd-firmware 500 with working NCQ TRIM. For Micron branded drives, see your sales rep for 501 updated firmware. Black listed drives will work correctly because these 502 drives work correctly so long as no NCQ TRIMs are sent to them. Given 503 this list is the same as found in Linux, it's believed there are no 504 other rogues in the market place. All other models from the above 505 vendors work. 506 507 To be safe, if you are at all concerned, you can quirk each of your 508 drives to prevent NCQ from being sent by setting: 509 kern.cam.ada.X.quirks="0x2" 510 in loader.conf. If the drive requires the 4k sector quirk, set the 511 quirks entry to 0x3. 512 51320160330: 514 The FAST_DEPEND build option has been removed and its functionality is 515 now the one true way. The old mkdep(1) style of 'make depend' has 516 been removed. See 20160311 for further details. 517 51820160317: 519 Resource range types have grown from unsigned long to uintmax_t. All 520 drivers, and anything using libdevinfo, need to be recompiled. 521 52220160311: 523 WITH_FAST_DEPEND is now enabled by default for in-tree and out-of-tree 524 builds. It no longer runs mkdep(1) during 'make depend', and the 525 'make depend' stage can safely be skipped now as it is auto ran 526 when building 'make all' and will generate all SRCS and DPSRCS before 527 building anything else. Dependencies are gathered at compile time with 528 -MF flags kept in separate .depend files per object file. Users should 529 run 'make cleandepend' once if using -DNO_CLEAN to clean out older 530 stale .depend files. 531 53220160306: 533 On amd64, clang 3.8.0 can now insert sections of type AMD64_UNWIND into 534 kernel modules. Therefore, if you load any kernel modules at boot time, 535 please install the boot loaders after you install the kernel, but before 536 rebooting, e.g.: 537 538 make buildworld 539 make kernel KERNCONF=YOUR_KERNEL_HERE 540 make -C sys/boot install 541 <reboot in single user> 542 543 Then follow the usual steps, described in the General Notes section, 544 below. 545 54620160305: 547 Clang, llvm, lldb and compiler-rt have been upgraded to 3.8.0. Please 548 see the 20141231 entry below for information about prerequisites and 549 upgrading, if you are not already using clang 3.5.0 or higher. 550 55120160301: 552 The AIO subsystem is now a standard part of the kernel. The 553 VFS_AIO kernel option and aio.ko kernel module have been removed. 554 Due to stability concerns, asynchronous I/O requests are only 555 permitted on sockets and raw disks by default. To enable 556 asynchronous I/O requests on all file types, set the 557 vfs.aio.enable_unsafe sysctl to a non-zero value. 558 55920160226: 560 The ELF object manipulation tool objcopy is now provided by the 561 ELF Tool Chain project rather than by GNU binutils. It should be a 562 drop-in replacement, with the addition of arm64 support. The 563 (temporary) src.conf knob WITHOUT_ELFCOPY_AS_OBJCOPY knob may be set 564 to obtain the GNU version if necessary. 565 56620160129: 567 Building ZFS pools on top of zvols is prohibited by default. That 568 feature has never worked safely; it's always been prone to deadlocks. 569 Using a zvol as the backing store for a VM guest's virtual disk will 570 still work, even if the guest is using ZFS. Legacy behavior can be 571 restored by setting vfs.zfs.vol.recursive=1. 572 57320160119: 574 The NONE and HPN patches has been removed from OpenSSH. They are 575 still available in the security/openssh-portable port. 576 57720160113: 578 With the addition of ypldap(8), a new _ypldap user is now required 579 during installworld. "mergemaster -p" can be used to add the user 580 prior to installworld, as documented in the handbook. 581 58220151216: 583 The tftp loader (pxeboot) now uses the option root-path directive. As a 584 consequence it no longer looks for a pxeboot.4th file on the tftp 585 server. Instead it uses the regular /boot infrastructure as with the 586 other loaders. 587 58820151211: 589 The code to start recording plug and play data into the modules has 590 been committed. While the old tools will properly build a new kernel, 591 a number of warnings about "unknown metadata record 4" will be produced 592 for an older kldxref. To avoid such warnings, make sure to rebuild 593 the kernel toolchain (or world). Make sure that you have r292078 or 594 later when trying to build 292077 or later before rebuilding. 595 59620151207: 597 Debug data files are now built by default with 'make buildworld' and 598 installed with 'make installworld'. This facilitates debugging but 599 requires more disk space both during the build and for the installed 600 world. Debug files may be disabled by setting WITHOUT_DEBUG_FILES=yes 601 in src.conf(5). 602 60320151130: 604 r291527 changed the internal interface between the nfsd.ko and 605 nfscommon.ko modules. As such, they must both be upgraded to-gether. 606 __FreeBSD_version has been bumped because of this. 607 60820151108: 609 Add support for unicode collation strings leads to a change of 610 order of files listed by ls(1) for example. To get back to the old 611 behaviour, set LC_COLLATE environment variable to "C". 612 613 Databases administrators will need to reindex their databases given 614 collation results will be different. 615 616 Due to a bug in install(1) it is recommended to remove the ancient 617 locales before running make installworld. 618 619 rm -rf /usr/share/locale/* 620 62120151030: 622 The OpenSSL has been upgraded to 1.0.2d. Any binaries requiring 623 libcrypto.so.7 or libssl.so.7 must be recompiled. 624 62520151020: 626 Qlogic 24xx/25xx firmware images were updated from 5.5.0 to 7.3.0. 627 Kernel modules isp_2400_multi and isp_2500_multi were removed and 628 should be replaced with isp_2400 and isp_2500 modules respectively. 629 63020151017: 631 The build previously allowed using 'make -n' to not recurse into 632 sub-directories while showing what commands would be executed, and 633 'make -n -n' to recursively show commands. Now 'make -n' will recurse 634 and 'make -N' will not. 635 63620151012: 637 If you specify SENDMAIL_MC or SENDMAIL_CF in make.conf, mergemaster 638 and etcupdate will now use this file. A custom sendmail.cf is now 639 updated via this mechanism rather than via installworld. If you had 640 excluded sendmail.cf in mergemaster.rc or etcupdate.conf, you may 641 want to remove the exclusion or change it to "always install". 642 /etc/mail/sendmail.cf is now managed the same way regardless of 643 whether SENDMAIL_MC/SENDMAIL_CF is used. If you are not using 644 SENDMAIL_MC/SENDMAIL_CF there should be no change in behavior. 645 64620151011: 647 Compatibility shims for legacy ATA device names have been removed. 648 It includes ATA_STATIC_ID kernel option, kern.cam.ada.legacy_aliases 649 and kern.geom.raid.legacy_aliases loader tunables, kern.devalias.* 650 environment variables, /dev/ad* and /dev/ar* symbolic links. 651 65220151006: 653 Clang, llvm, lldb, compiler-rt and libc++ have been upgraded to 3.7.0. 654 Please see the 20141231 entry below for information about prerequisites 655 and upgrading, if you are not already using clang 3.5.0 or higher. 656 65720150924: 658 Kernel debug files have been moved to /usr/lib/debug/boot/kernel/, 659 and renamed from .symbols to .debug. This reduces the size requirements 660 on the boot partition or file system and provides consistency with 661 userland debug files. 662 663 When using the supported kernel installation method the 664 /usr/lib/debug/boot/kernel directory will be renamed (to kernel.old) 665 as is done with /boot/kernel. 666 667 Developers wishing to maintain the historical behavior of installing 668 debug files in /boot/kernel/ can set KERN_DEBUGDIR="" in src.conf(5). 669 67020150827: 671 The wireless drivers had undergone changes that remove the 'parent 672 interface' from the ifconfig -l output. The rc.d network scripts 673 used to check presence of a parent interface in the list, so old 674 scripts would fail to start wireless networking. Thus, etcupdate(3) 675 or mergemaster(8) run is required after kernel update, to update your 676 rc.d scripts in /etc. 677 67820150827: 679 pf no longer supports 'scrub fragment crop' or 'scrub fragment drop-ovl' 680 These configurations are now automatically interpreted as 681 'scrub fragment reassemble'. 682 68320150817: 684 Kernel-loadable modules for the random(4) device are back. To use 685 them, the kernel must have 686 687 device random 688 options RANDOM_LOADABLE 689 690 kldload(8) can then be used to load random_fortuna.ko 691 or random_yarrow.ko. Please note that due to the indirect 692 function calls that the loadable modules need to provide, 693 the build-in variants will be slightly more efficient. 694 695 The random(4) kernel option RANDOM_DUMMY has been retired due to 696 unpopularity. It was not all that useful anyway. 697 69820150813: 699 The WITHOUT_ELFTOOLCHAIN_TOOLS src.conf(5) knob has been retired. 700 Control over building the ELF Tool Chain tools is now provided by 701 the WITHOUT_TOOLCHAIN knob. 702 70320150810: 704 The polarity of Pulse Per Second (PPS) capture events with the 705 uart(4) driver has been corrected. Prior to this change the PPS 706 "assert" event corresponded to the trailing edge of a positive PPS 707 pulse and the "clear" event was the leading edge of the next pulse. 708 709 As the width of a PPS pulse in a typical GPS receiver is on the 710 order of 1 millisecond, most users will not notice any significant 711 difference with this change. 712 713 Anyone who has compensated for the historical polarity reversal by 714 configuring a negative offset equal to the pulse width will need to 715 remove that workaround. 716 71720150809: 718 The default group assigned to /dev/dri entries has been changed 719 from 'wheel' to 'video' with the id of '44'. If you want to have 720 access to the dri devices please add yourself to the video group 721 with: 722 723 # pw groupmod video -m $USER 724 72520150806: 726 The menu.rc and loader.rc files will now be replaced during 727 upgrades. Please migrate local changes to menu.rc.local and 728 loader.rc.local instead. 729 73020150805: 731 GNU Binutils versions of addr2line, c++filt, nm, readelf, size, 732 strings and strip have been removed. The src.conf(5) knob 733 WITHOUT_ELFTOOLCHAIN_TOOLS no longer provides the binutils tools. 734 73520150728: 736 As ZFS requires more kernel stack pages than is the default on some 737 architectures e.g. i386, it now warns if KSTACK_PAGES is less than 738 ZFS_MIN_KSTACK_PAGES (which is 4 at the time of writing). 739 740 Please consider using 'options KSTACK_PAGES=X' where X is greater 741 than or equal to ZFS_MIN_KSTACK_PAGES i.e. 4 in such configurations. 742 74320150706: 744 sendmail has been updated to 8.15.2. Starting with FreeBSD 11.0 745 and sendmail 8.15, sendmail uses uncompressed IPv6 addresses by 746 default, i.e., they will not contain "::". For example, instead 747 of ::1, it will be 0:0:0:0:0:0:0:1. This permits a zero subnet 748 to have a more specific match, such as different map entries for 749 IPv6:0:0 vs IPv6:0. This change requires that configuration 750 data (including maps, files, classes, custom ruleset, etc.) must 751 use the same format, so make certain such configuration data is 752 upgrading. As a very simple check search for patterns like 753 'IPv6:[0-9a-fA-F:]*::' and 'IPv6::'. To return to the old 754 behavior, set the m4 option confUSE_COMPRESSED_IPV6_ADDRESSES or 755 the cf option UseCompressedIPv6Addresses. 756 75720150630: 758 The default kernel entropy-processing algorithm is now 759 Fortuna, replacing Yarrow. 760 761 Assuming you have 'device random' in your kernel config 762 file, the configurations allow a kernel option to override 763 this default. You may choose *ONE* of: 764 765 options RANDOM_YARROW # Legacy /dev/random algorithm. 766 options RANDOM_DUMMY # Blocking-only driver. 767 768 If you have neither, you get Fortuna. For most people, 769 read no further, Fortuna will give a /dev/random that works 770 like it always used to, and the difference will be irrelevant. 771 772 If you remove 'device random', you get *NO* kernel-processed 773 entropy at all. This may be acceptable to folks building 774 embedded systems, but has complications. Carry on reading, 775 and it is assumed you know what you need. 776 777 *PLEASE* read random(4) and random(9) if you are in the 778 habit of tweaking kernel configs, and/or if you are a member 779 of the embedded community, wanting specific and not-usual 780 behaviour from your security subsystems. 781 782 NOTE!! If you use RANDOM_DUMMY and/or have no 'device 783 random', you will NOT have a functioning /dev/random, and 784 many cryptographic features will not work, including SSH. 785 You may also find strange behaviour from the random(3) set 786 of library functions, in particular sranddev(3), srandomdev(3) 787 and arc4random(3). The reason for this is that the KERN_ARND 788 sysctl only returns entropy if it thinks it has some to 789 share, and with RANDOM_DUMMY or no 'device random' this 790 will never happen. 791 79220150623: 793 An additional fix for the issue described in the 20150614 sendmail 794 entry below has been been committed in revision 284717. 795 79620150616: 797 FreeBSD's old make (fmake) has been removed from the system. It is 798 available as the devel/fmake port or via pkg install fmake. 799 80020150615: 801 The fix for the issue described in the 20150614 sendmail entry 802 below has been been committed in revision 284436. The work 803 around described in that entry is no longer needed unless the 804 default setting is overridden by a confDH_PARAMETERS configuration 805 setting of '5' or pointing to a 512 bit DH parameter file. 806 80720150614: 808 ALLOW_DEPRECATED_ATF_TOOLS/ATFFILE support has been removed from 809 atf.test.mk (included from bsd.test.mk). Please upgrade devel/atf 810 and devel/kyua to version 0.20+ and adjust any calling code to work 811 with Kyuafile and kyua. 812 81320150614: 814 The import of openssl to address the FreeBSD-SA-15:10.openssl 815 security advisory includes a change which rejects handshakes 816 with DH parameters below 768 bits. sendmail releases prior 817 to 8.15.2 (not yet released), defaulted to a 512 bit 818 DH parameter setting for client connections. To work around 819 this interoperability, sendmail can be configured to use a 820 2048 bit DH parameter by: 821 822 1. Edit /etc/mail/`hostname`.mc 823 2. If a setting for confDH_PARAMETERS does not exist or 824 exists and is set to a string beginning with '5', 825 replace it with '2'. 826 3. If a setting for confDH_PARAMETERS exists and is set to 827 a file path, create a new file with: 828 openssl dhparam -out /path/to/file 2048 829 4. Rebuild the .cf file: 830 cd /etc/mail/; make; make install 831 5. Restart sendmail: 832 cd /etc/mail/; make restart 833 834 A sendmail patch is coming, at which time this file will be 835 updated. 836 83720150604: 838 Generation of legacy formatted entries have been disabled by default 839 in pwd_mkdb(8), as all base system consumers of the legacy formatted 840 entries were converted to use the new format by default when the new, 841 machine independent format have been added and supported since FreeBSD 842 5.x. 843 844 Please see the pwd_mkdb(8) manual page for further details. 845 84620150525: 847 Clang and llvm have been upgraded to 3.6.1 release. Please see the 848 20141231 entry below for information about prerequisites and upgrading, 849 if you are not already using 3.5.0 or higher. 850 85120150521: 852 TI platform code switched to using vendor DTS files and this update 853 may break existing systems running on Beaglebone, Beaglebone Black, 854 and Pandaboard: 855 856 - dtb files should be regenerated/reinstalled. Filenames are the 857 same but content is different now 858 - GPIO addressing was changed, now each GPIO bank (32 pins per bank) 859 has its own /dev/gpiocX device, e.g. pin 121 on /dev/gpioc0 in old 860 addressing scheme is now pin 25 on /dev/gpioc3. 861 - Pandaboard: /etc/ttys should be updated, serial console device is 862 now /dev/ttyu2, not /dev/ttyu0 863 86420150501: 865 soelim(1) from gnu/usr.bin/groff has been replaced by usr.bin/soelim. 866 If you need the GNU extension from groff soelim(1), install groff 867 from package: pkg install groff, or via ports: textproc/groff. 868 86920150423: 870 chmod, chflags, chown and chgrp now affect symlinks in -R mode as 871 defined in symlink(7); previously symlinks were silently ignored. 872 87320150415: 874 The const qualifier has been removed from iconv(3) to comply with 875 POSIX. The ports tree is aware of this from r384038 onwards. 876 87720150416: 878 Libraries specified by LIBADD in Makefiles must have a corresponding 879 DPADD_<lib> variable to ensure correct dependencies. This is now 880 enforced in src.libnames.mk. 881 88220150324: 883 From legacy ata(4) driver was removed support for SATA controllers 884 supported by more functional drivers ahci(4), siis(4) and mvs(4). 885 Kernel modules ataahci and ataadaptec were removed completely, 886 replaced by ahci and mvs modules respectively. 887 88820150315: 889 Clang, llvm and lldb have been upgraded to 3.6.0 release. Please see 890 the 20141231 entry below for information about prerequisites and 891 upgrading, if you are not already using 3.5.0 or higher. 892 89320150307: 894 The 32-bit PowerPC kernel has been changed to a position-independent 895 executable. This can only be booted with a version of loader(8) 896 newer than January 31, 2015, so make sure to update both world and 897 kernel before rebooting. 898 89920150217: 900 If you are running a -CURRENT kernel since r273872 (Oct 30th, 2014), 901 but before r278950, the RNG was not seeded properly. Immediately 902 upgrade the kernel to r278950 or later and regenerate any keys (e.g. 903 ssh keys or openssl keys) that were generated w/ a kernel from that 904 range. This does not affect programs that directly used /dev/random 905 or /dev/urandom. All userland uses of arc4random(3) are affected. 906 90720150210: 908 The autofs(4) ABI was changed in order to restore binary compatibility 909 with 10.1-RELEASE. The automountd(8) daemon needs to be rebuilt to work 910 with the new kernel. 911 91220150131: 913 The powerpc64 kernel has been changed to a position-independent 914 executable. This can only be booted with a new version of loader(8), 915 so make sure to update both world and kernel before rebooting. 916 91720150118: 918 Clang and llvm have been upgraded to 3.5.1 release. This is a bugfix 919 only release, no new features have been added. Please see the 20141231 920 entry below for information about prerequisites and upgrading, if you 921 are not already using 3.5.0. 922 92320150107: 924 ELF tools addr2line, elfcopy (strip), nm, size, and strings are now 925 taken from the ELF Tool Chain project rather than GNU binutils. They 926 should be drop-in replacements, with the addition of arm64 support. 927 The WITHOUT_ELFTOOLCHAIN_TOOLS= knob may be used to obtain the 928 binutils tools, if necessary. See 20150805 for updated information. 929 93020150105: 931 The default Unbound configuration now enables remote control 932 using a local socket. Users who have already enabled the 933 local_unbound service should regenerate their configuration 934 by running "service local_unbound setup" as root. 935 93620150102: 937 The GNU texinfo and GNU info pages have been removed. 938 To be able to view GNU info pages please install texinfo from ports. 939 94020141231: 941 Clang, llvm and lldb have been upgraded to 3.5.0 release. 942 943 As of this release, a prerequisite for building clang, llvm and lldb is 944 a C++11 capable compiler and C++11 standard library. This means that to 945 be able to successfully build the cross-tools stage of buildworld, with 946 clang as the bootstrap compiler, your system compiler or cross compiler 947 should either be clang 3.3 or later, or gcc 4.8 or later, and your 948 system C++ library should be libc++, or libdstdc++ from gcc 4.8 or 949 later. 950 951 On any standard FreeBSD 10.x or 11.x installation, where clang and 952 libc++ are on by default (that is, on x86 or arm), this should work out 953 of the box. 954 955 On 9.x installations where clang is enabled by default, e.g. on x86 and 956 powerpc, libc++ will not be enabled by default, so libc++ should be 957 built (with clang) and installed first. If both clang and libc++ are 958 missing, build clang first, then use it to build libc++. 959 960 On 8.x and earlier installations, upgrade to 9.x first, and then follow 961 the instructions for 9.x above. 962 963 Sparc64 and mips users are unaffected, as they still use gcc 4.2.1 by 964 default, and do not build clang. 965 966 Many embedded systems are resource constrained, and will not be able to 967 build clang in a reasonable time, or in some cases at all. In those 968 cases, cross building bootable systems on amd64 is a workaround. 969 970 This new version of clang introduces a number of new warnings, of which 971 the following are most likely to appear: 972 973 -Wabsolute-value 974 975 This warns in two cases, for both C and C++: 976 * When the code is trying to take the absolute value of an unsigned 977 quantity, which is effectively a no-op, and almost never what was 978 intended. The code should be fixed, if at all possible. If you are 979 sure that the unsigned quantity can be safely cast to signed, without 980 loss of information or undefined behavior, you can add an explicit 981 cast, or disable the warning. 982 983 * When the code is trying to take an absolute value, but the called 984 abs() variant is for the wrong type, which can lead to truncation. 985 If you want to disable the warning instead of fixing the code, please 986 make sure that truncation will not occur, or it might lead to unwanted 987 side-effects. 988 989 -Wtautological-undefined-compare and 990 -Wundefined-bool-conversion 991 992 These warn when C++ code is trying to compare 'this' against NULL, while 993 'this' should never be NULL in well-defined C++ code. However, there is 994 some legacy (pre C++11) code out there, which actively abuses this 995 feature, which was less strictly defined in previous C++ versions. 996 997 Squid and openjdk do this, for example. The warning can be turned off 998 for C++98 and earlier, but compiling the code in C++11 mode might result 999 in unexpected behavior; for example, the parts of the program that are 1000 unreachable could be optimized away. 1001 100220141222: 1003 The old NFS client and server (kernel options NFSCLIENT, NFSSERVER) 1004 kernel sources have been removed. The .h files remain, since some 1005 utilities include them. This will need to be fixed later. 1006 If "mount -t oldnfs ..." is attempted, it will fail. 1007 If the "-o" option on mountd(8), nfsd(8) or nfsstat(1) is used, 1008 the utilities will report errors. 1009 101020141121: 1011 The handling of LOCAL_LIB_DIRS has been altered to skip addition of 1012 directories to top level SUBDIR variable when their parent 1013 directory is included in LOCAL_DIRS. Users with build systems with 1014 such hierarchies and without SUBDIR entries in the parent 1015 directory Makefiles should add them or add the directories to 1016 LOCAL_DIRS. 1017 101820141109: 1019 faith(4) and faithd(8) have been removed from the base system. Faith 1020 has been obsolete for a very long time. 1021 102220141104: 1023 vt(4), the new console driver, is enabled by default. It brings 1024 support for Unicode and double-width characters, as well as 1025 support for UEFI and integration with the KMS kernel video 1026 drivers. 1027 1028 You may need to update your console settings in /etc/rc.conf, 1029 most probably the keymap. During boot, /etc/rc.d/syscons will 1030 indicate what you need to do. 1031 1032 vt(4) still has issues and lacks some features compared to 1033 syscons(4). See the wiki for up-to-date information: 1034 https://wiki.freebsd.org/Newcons 1035 1036 If you want to keep using syscons(4), you can do so by adding 1037 the following line to /boot/loader.conf: 1038 kern.vty=sc 1039 104020141102: 1041 pjdfstest has been integrated into kyua as an opt-in test suite. 1042 Please see share/doc/pjdfstest/README for more details on how to 1043 execute it. 1044 104520141009: 1046 gperf has been removed from the base system for architectures 1047 that use clang. Ports that require gperf will obtain it from the 1048 devel/gperf port. 1049 105020140923: 1051 pjdfstest has been moved from tools/regression/pjdfstest to 1052 contrib/pjdfstest . 1053 105420140922: 1055 At svn r271982, The default linux compat kernel ABI has been adjusted 1056 to 2.6.18 in support of the linux-c6 compat ports infrastructure 1057 update. If you wish to continue using the linux-f10 compat ports, 1058 add compat.linux.osrelease=2.6.16 to your local sysctl.conf. Users are 1059 encouraged to update their linux-compat packages to linux-c6 during 1060 their next update cycle. 1061 106220140729: 1063 The ofwfb driver, used to provide a graphics console on PowerPC when 1064 using vt(4), no longer allows mmap() of all physical memory. This 1065 will prevent Xorg on PowerPC with some ATI graphics cards from 1066 initializing properly unless x11-servers/xorg-server is updated to 1067 1.12.4_8 or newer. 1068 106920140723: 1070 The xdev targets have been converted to using TARGET and 1071 TARGET_ARCH instead of XDEV and XDEV_ARCH. 1072 107320140719: 1074 The default unbound configuration has been modified to address 1075 issues with reverse lookups on networks that use private 1076 address ranges. If you use the local_unbound service, run 1077 "service local_unbound setup" as root to regenerate your 1078 configuration, then "service local_unbound reload" to load the 1079 new configuration. 1080 108120140709: 1082 The GNU texinfo and GNU info pages are not built and installed 1083 anymore, WITH_INFO knob has been added to allow to built and install 1084 them again. 1085 UPDATE: see 20150102 entry on texinfo's removal 1086 108720140708: 1088 The GNU readline library is now an INTERNALLIB - that is, it is 1089 statically linked into consumers (GDB and variants) in the base 1090 system, and the shared library is no longer installed. The 1091 devel/readline port is available for third party software that 1092 requires readline. 1093 109420140702: 1095 The Itanium architecture (ia64) has been removed from the list of 1096 known architectures. This is the first step in the removal of the 1097 architecture. 1098 109920140701: 1100 Commit r268115 has added NFSv4.1 server support, merged from 1101 projects/nfsv4.1-server. Since this includes changes to the 1102 internal interfaces between the NFS related modules, a full 1103 build of the kernel and modules will be necessary. 1104 __FreeBSD_version has been bumped. 1105 110620140629: 1107 The WITHOUT_VT_SUPPORT kernel config knob has been renamed 1108 WITHOUT_VT. (The other _SUPPORT knobs have a consistent meaning 1109 which differs from the behaviour controlled by this knob.) 1110 111120140619: 1112 Maximal length of the serial number in CTL was increased from 16 to 1113 64 chars, that breaks ABI. All CTL-related tools, such as ctladm 1114 and ctld, need to be rebuilt to work with a new kernel. 1115 111620140606: 1117 The libatf-c and libatf-c++ major versions were downgraded to 0 and 1118 1 respectively to match the upstream numbers. They were out of 1119 sync because, when they were originally added to FreeBSD, the 1120 upstream versions were not respected. These libraries are private 1121 and not yet built by default, so renumbering them should be a 1122 non-issue. However, unclean source trees will yield broken test 1123 programs once the operator executes "make delete-old-libs" after a 1124 "make installworld". 1125 1126 Additionally, the atf-sh binary was made private by moving it into 1127 /usr/libexec/. Already-built shell test programs will keep the 1128 path to the old binary so they will break after "make delete-old" 1129 is run. 1130 1131 If you are using WITH_TESTS=yes (not the default), wipe the object 1132 tree and rebuild from scratch to prevent spurious test failures. 1133 This is only needed once: the misnumbered libraries and misplaced 1134 binaries have been added to OptionalObsoleteFiles.inc so they will 1135 be removed during a clean upgrade. 1136 113720140512: 1138 Clang and llvm have been upgraded to 3.4.1 release. 1139 114020140508: 1141 We bogusly installed src.opts.mk in /usr/share/mk. This file should 1142 be removed to avoid issues in the future (and has been added to 1143 ObsoleteFiles.inc). 1144 114520140505: 1146 /etc/src.conf now affects only builds of the FreeBSD src tree. In the 1147 past, it affected all builds that used the bsd.*.mk files. The old 1148 behavior was a bug, but people may have relied upon it. To get this 1149 behavior back, you can .include /etc/src.conf from /etc/make.conf 1150 (which is still global and isn't changed). This also changes the 1151 behavior of incremental builds inside the tree of individual 1152 directories. Set MAKESYSPATH to ".../share/mk" to do that. 1153 Although this has survived make universe and some upgrade scenarios, 1154 other upgrade scenarios may have broken. At least one form of 1155 temporary breakage was fixed with MAKESYSPATH settings for buildworld 1156 as well... In cases where MAKESYSPATH isn't working with this 1157 setting, you'll need to set it to the full path to your tree. 1158 1159 One side effect of all this cleaning up is that bsd.compiler.mk 1160 is no longer implicitly included by bsd.own.mk. If you wish to 1161 use COMPILER_TYPE, you must now explicitly include bsd.compiler.mk 1162 as well. 1163 116420140430: 1165 The lindev device has been removed since /dev/full has been made a 1166 standard device. __FreeBSD_version has been bumped. 1167 116820140424: 1169 The knob WITHOUT_VI was added to the base system, which controls 1170 building ex(1), vi(1), etc. Older releases of FreeBSD required ex(1) 1171 in order to reorder files share/termcap and didn't build ex(1) as a 1172 build tool, so building/installing with WITH_VI is highly advised for 1173 build hosts for older releases. 1174 1175 This issue has been fixed in stable/9 and stable/10 in r277022 and 1176 r276991, respectively. 1177 117820140418: 1179 The YES_HESIOD knob has been removed. It has been obsolete for 1180 a decade. Please move to using WITH_HESIOD instead or your builds 1181 will silently lack HESIOD. 1182 118320140405: 1184 The uart(4) driver has been changed with respect to its handling 1185 of the low-level console. Previously the uart(4) driver prevented 1186 any process from changing the baudrate or the CLOCAL and HUPCL 1187 control flags. By removing the restrictions, operators can make 1188 changes to the serial console port without having to reboot. 1189 However, when getty(8) is started on the serial device that is 1190 associated with the low-level console, a misconfigured terminal 1191 line in /etc/ttys will now have a real impact. 1192 Before upgrading the kernel, make sure that /etc/ttys has the 1193 serial console device configured as 3wire without baudrate to 1194 preserve the previous behaviour. E.g: 1195 ttyu0 "/usr/libexec/getty 3wire" vt100 on secure 1196 119720140306: 1198 Support for libwrap (TCP wrappers) in rpcbind was disabled by default 1199 to improve performance. To re-enable it, if needed, run rpcbind 1200 with command line option -W. 1201 120220140226: 1203 Switched back to the GPL dtc compiler due to updates in the upstream 1204 dts files not being supported by the BSDL dtc compiler. You will need 1205 to rebuild your kernel toolchain to pick up the new compiler. Core dumps 1206 may result while building dtb files during a kernel build if you fail 1207 to do so. Set WITHOUT_GPL_DTC if you require the BSDL compiler. 1208 120920140216: 1210 Clang and llvm have been upgraded to 3.4 release. 1211 121220140216: 1213 The nve(4) driver has been removed. Please use the nfe(4) driver 1214 for NVIDIA nForce MCP Ethernet adapters instead. 1215 121620140212: 1217 An ABI incompatibility crept into the libc++ 3.4 import in r261283. 1218 This could cause certain C++ applications using shared libraries built 1219 against the previous version of libc++ to crash. The incompatibility 1220 has now been fixed, but any C++ applications or shared libraries built 1221 between r261283 and r261801 should be recompiled. 1222 122320140204: 1224 OpenSSH will now ignore errors caused by kernel lacking of Capsicum 1225 capability mode support. Please note that enabling the feature in 1226 kernel is still highly recommended. 1227 122820140131: 1229 OpenSSH is now built with sandbox support, and will use sandbox as 1230 the default privilege separation method. This requires Capsicum 1231 capability mode support in kernel. 1232 123320140128: 1234 The libelf and libdwarf libraries have been updated to newer 1235 versions from upstream. Shared library version numbers for 1236 these two libraries were bumped. Any ports or binaries 1237 requiring these two libraries should be recompiled. 1238 __FreeBSD_version is bumped to 1100006. 1239 124020140110: 1241 If a Makefile in a tests/ directory was auto-generating a Kyuafile 1242 instead of providing an explicit one, this would prevent such 1243 Makefile from providing its own Kyuafile in the future during 1244 NO_CLEAN builds. This has been fixed in the Makefiles but manual 1245 intervention is needed to clean an objdir if you use NO_CLEAN: 1246 # find /usr/obj -name Kyuafile | xargs rm -f 1247 124820131213: 1249 The behavior of gss_pseudo_random() for the krb5 mechanism 1250 has changed, for applications requesting a longer random string 1251 than produced by the underlying enctype's pseudo-random() function. 1252 In particular, the random string produced from a session key of 1253 enctype aes256-cts-hmac-sha1-96 or aes256-cts-hmac-sha1-96 will 1254 be different at the 17th octet and later, after this change. 1255 The counter used in the PRF+ construction is now encoded as a 1256 big-endian integer in accordance with RFC 4402. 1257 __FreeBSD_version is bumped to 1100004. 1258 125920131108: 1260 The WITHOUT_ATF build knob has been removed and its functionality 1261 has been subsumed into the more generic WITHOUT_TESTS. If you were 1262 using the former to disable the build of the ATF libraries, you 1263 should change your settings to use the latter. 1264 126520131025: 1266 The default version of mtree is nmtree which is obtained from 1267 NetBSD. The output is generally the same, but may vary 1268 slightly. If you found you need identical output adding 1269 "-F freebsd9" to the command line should do the trick. For the 1270 time being, the old mtree is available as fmtree. 1271 127220131014: 1273 libbsdyml has been renamed to libyaml and moved to /usr/lib/private. 1274 This will break ports-mgmt/pkg. Rebuild the port, or upgrade to pkg 1275 1.1.4_8 and verify bsdyml not linked in, before running "make 1276 delete-old-libs": 1277 # make -C /usr/ports/ports-mgmt/pkg build deinstall install clean 1278 or 1279 # pkg install pkg; ldd /usr/local/sbin/pkg | grep bsdyml 1280 128120131010: 1282 The stable/10 branch has been created in subversion from head 1283 revision r256279. 1284 128520131010: 1286 The rc.d/jail script has been updated to support jail(8) 1287 configuration file. The "jail_<jname>_*" rc.conf(5) variables 1288 for per-jail configuration are automatically converted to 1289 /var/run/jail.<jname>.conf before the jail(8) utility is invoked. 1290 This is transparently backward compatible. See below about some 1291 incompatibilities and rc.conf(5) manual page for more details. 1292 1293 These variables are now deprecated in favor of jail(8) configuration 1294 file. One can use "rc.d/jail config <jname>" command to generate 1295 a jail(8) configuration file in /var/run/jail.<jname>.conf without 1296 running the jail(8) utility. The default pathname of the 1297 configuration file is /etc/jail.conf and can be specified by 1298 using $jail_conf or $jail_<jname>_conf variables. 1299 1300 Please note that jail_devfs_ruleset accepts an integer at 1301 this moment. Please consider to rewrite the ruleset name 1302 with an integer. 1303 130420130930: 1305 BIND has been removed from the base system. If all you need 1306 is a local resolver, simply enable and start the local_unbound 1307 service instead. Otherwise, several versions of BIND are 1308 available in the ports tree. The dns/bind99 port is one example. 1309 1310 With this change, nslookup(1) and dig(1) are no longer in the base 1311 system. Users should instead use host(1) and drill(1) which are 1312 in the base system. Alternatively, nslookup and dig can 1313 be obtained by installing the dns/bind-tools port. 1314 131520130916: 1316 With the addition of unbound(8), a new unbound user is now 1317 required during installworld. "mergemaster -p" can be used to 1318 add the user prior to installworld, as documented in the handbook. 1319 132020130911: 1321 OpenSSH is now built with DNSSEC support, and will by default 1322 silently trust signed SSHFP records. This can be controlled with 1323 the VerifyHostKeyDNS client configuration setting. DNSSEC support 1324 can be disabled entirely with the WITHOUT_LDNS option in src.conf. 1325 132620130906: 1327 The GNU Compiler Collection and C++ standard library (libstdc++) 1328 are no longer built by default on platforms where clang is the system 1329 compiler. You can enable them with the WITH_GCC and WITH_GNUCXX 1330 options in src.conf. 1331 133220130905: 1333 The PROCDESC kernel option is now part of the GENERIC kernel 1334 configuration and is required for the rwhod(8) to work. 1335 If you are using custom kernel configuration, you should include 1336 'options PROCDESC'. 1337 133820130905: 1339 The API and ABI related to the Capsicum framework was modified 1340 in backward incompatible way. The userland libraries and programs 1341 have to be recompiled to work with the new kernel. This includes the 1342 following libraries and programs, but the whole buildworld is 1343 advised: libc, libprocstat, dhclient, tcpdump, hastd, hastctl, 1344 kdump, procstat, rwho, rwhod, uniq. 1345 134620130903: 1347 AES-NI intrinsic support has been added to gcc. The AES-NI module 1348 has been updated to use this support. A new gcc is required to build 1349 the aesni module on both i386 and amd64. 1350 135120130821: 1352 The PADLOCK_RNG and RDRAND_RNG kernel options are now devices. 1353 Thus "device padlock_rng" and "device rdrand_rng" should be 1354 used instead of "options PADLOCK_RNG" & "options RDRAND_RNG". 1355 135620130813: 1357 WITH_ICONV has been split into two feature sets. WITH_ICONV now 1358 enables just the iconv* functionality and is now on by default. 1359 WITH_LIBICONV_COMPAT enables the libiconv api and link time 1360 compatibility. Set WITHOUT_ICONV to build the old way. 1361 If you have been using WITH_ICONV before, you will very likely 1362 need to turn on WITH_LIBICONV_COMPAT. 1363 136420130806: 1365 INVARIANTS option now enables DEBUG for code with OpenSolaris and 1366 Illumos origin, including ZFS. If you have INVARIANTS in your 1367 kernel configuration, then there is no need to set DEBUG or ZFS_DEBUG 1368 explicitly. 1369 DEBUG used to enable witness(9) tracking of OpenSolaris (mostly ZFS) 1370 locks if WITNESS option was set. Because that generated a lot of 1371 witness(9) reports and all of them were believed to be false 1372 positives, this is no longer done. New option OPENSOLARIS_WITNESS 1373 can be used to achieve the previous behavior. 1374 137520130806: 1376 Timer values in IPv6 data structures now use time_uptime instead 1377 of time_second. Although this is not a user-visible functional 1378 change, userland utilities which directly use them---ndp(8), 1379 rtadvd(8), and rtsold(8) in the base system---need to be updated 1380 to r253970 or later. 1381 138220130802: 1383 find -delete can now delete the pathnames given as arguments, 1384 instead of only files found below them or if the pathname did 1385 not contain any slashes. Formerly, the following error message 1386 would result: 1387 1388 find: -delete: <path>: relative path potentially not safe 1389 1390 Deleting the pathnames given as arguments can be prevented 1391 without error messages using -mindepth 1 or by changing 1392 directory and passing "." as argument to find. This works in the 1393 old as well as the new version of find. 1394 139520130726: 1396 Behavior of devfs rules path matching has been changed. 1397 Pattern is now always matched against fully qualified devfs 1398 path and slash characters must be explicitly matched by 1399 slashes in pattern (FNM_PATHNAME). Rulesets involving devfs 1400 subdirectories must be reviewed. 1401 140220130716: 1403 The default ARM ABI has changed to the ARM EABI. The old ABI is 1404 incompatible with the ARM EABI and all programs and modules will 1405 need to be rebuilt to work with a new kernel. 1406 1407 To keep using the old ABI ensure the WITHOUT_ARM_EABI knob is set. 1408 1409 NOTE: Support for the old ABI will be removed in the future and 1410 users are advised to upgrade. 1411 141220130709: 1413 pkg_install has been disconnected from the build if you really need it 1414 you should add WITH_PKGTOOLS in your src.conf(5). 1415 141620130709: 1417 Most of network statistics structures were changed to be able 1418 keep 64-bits counters. Thus all tools, that work with networking 1419 statistics, must be rebuilt (netstat(1), bsnmpd(1), etc.) 1420 142120130618: 1422 Fix a bug that allowed a tracing process (e.g. gdb) to write 1423 to a memory-mapped file in the traced process's address space 1424 even if neither the traced process nor the tracing process had 1425 write access to that file. 1426 142720130615: 1428 CVS has been removed from the base system. An exact copy 1429 of the code is available from the devel/cvs port. 1430 143120130613: 1432 Some people report the following error after the switch to bmake: 1433 1434 make: illegal option -- J 1435 usage: make [-BPSXeiknpqrstv] [-C directory] [-D variable] 1436 ... 1437 *** [buildworld] Error code 2 1438 1439 this likely due to an old instance of make in 1440 ${MAKEPATH} (${MAKEOBJDIRPREFIX}${.CURDIR}/make.${MACHINE}) 1441 which src/Makefile will use that blindly, if it exists, so if 1442 you see the above error: 1443 1444 rm -rf `make -V MAKEPATH` 1445 1446 should resolve it. 1447 144820130516: 1449 Use bmake by default. 1450 Whereas before one could choose to build with bmake via 1451 -DWITH_BMAKE one must now use -DWITHOUT_BMAKE to use the old 1452 make. The goal is to remove these knobs for 10-RELEASE. 1453 1454 It is worth noting that bmake (like gmake) treats the command 1455 line as the unit of failure, rather than statements within the 1456 command line. Thus '(cd some/where && dosomething)' is safer 1457 than 'cd some/where; dosomething'. The '()' allows consistent 1458 behavior in parallel build. 1459 146020130429: 1461 Fix a bug that allows NFS clients to issue READDIR on files. 1462 146320130426: 1464 The WITHOUT_IDEA option has been removed because 1465 the IDEA patent expired. 1466 146720130426: 1468 The sysctl which controls TRIM support under ZFS has been renamed 1469 from vfs.zfs.trim_disable -> vfs.zfs.trim.enabled and has been 1470 enabled by default. 1471 147220130425: 1473 The mergemaster command now uses the default MAKEOBJDIRPREFIX 1474 rather than creating it's own in the temporary directory in 1475 order allow access to bootstrapped versions of tools such as 1476 install and mtree. When upgrading from version of FreeBSD where 1477 the install command does not support -l, you will need to 1478 install a new mergemaster command if mergemaster -p is required. 1479 This can be accomplished with the command (cd src/usr.sbin/mergemaster 1480 && make install). 1481 148220130404: 1483 Legacy ATA stack, disabled and replaced by new CAM-based one since 1484 FreeBSD 9.0, completely removed from the sources. Kernel modules 1485 atadisk and atapi*, user-level tools atacontrol and burncd are 1486 removed. Kernel option `options ATA_CAM` is now permanently enabled 1487 and removed. 1488 148920130319: 1490 SOCK_CLOEXEC and SOCK_NONBLOCK flags have been added to socket(2) 1491 and socketpair(2). Software, in particular Kerberos, may 1492 automatically detect and use these during building. The resulting 1493 binaries will not work on older kernels. 1494 149520130308: 1496 CTL_DISABLE has also been added to the sparc64 GENERIC (for further 1497 information, see the respective 20130304 entry). 1498 149920130304: 1500 Recent commits to callout(9) changed the size of struct callout, 1501 so the KBI is probably heavily disturbed. Also, some functions 1502 in callout(9)/sleep(9)/sleepqueue(9)/condvar(9) KPIs were replaced 1503 by macros. Every kernel module using it won't load, so rebuild 1504 is requested. 1505 1506 The ctl device has been re-enabled in GENERIC for i386 and amd64, 1507 but does not initialize by default (because of the new CTL_DISABLE 1508 option) to save memory. To re-enable it, remove the CTL_DISABLE 1509 option from the kernel config file or set kern.cam.ctl.disable=0 1510 in /boot/loader.conf. 1511 151220130301: 1513 The ctl device has been disabled in GENERIC for i386 and amd64. 1514 This was done due to the extra memory being allocated at system 1515 initialisation time by the ctl driver which was only used if 1516 a CAM target device was created. This makes a FreeBSD system 1517 unusable on 128MB or less of RAM. 1518 151920130208: 1520 A new compression method (lz4) has been merged to -HEAD. Please 1521 refer to zpool-features(7) for more information. 1522 1523 Please refer to the "ZFS notes" section of this file for information 1524 on upgrading boot ZFS pools. 1525 152620130129: 1527 A BSD-licensed patch(1) variant has been added and is installed 1528 as bsdpatch, being the GNU version the default patch. 1529 To inverse the logic and use the BSD-licensed one as default, 1530 while having the GNU version installed as gnupatch, rebuild 1531 and install world with the WITH_BSD_PATCH knob set. 1532 153320130121: 1534 Due to the use of the new -l option to install(1) during build 1535 and install, you must take care not to directly set the INSTALL 1536 make variable in your /etc/make.conf, /etc/src.conf, or on the 1537 command line. If you wish to use the -C flag for all installs 1538 you may be able to add INSTALL+=-C to /etc/make.conf or 1539 /etc/src.conf. 1540 154120130118: 1542 The install(1) option -M has changed meaning and now takes an 1543 argument that is a file or path to append logs to. In the 1544 unlikely event that -M was the last option on the command line 1545 and the command line contained at least two files and a target 1546 directory the first file will have logs appended to it. The -M 1547 option served little practical purpose in the last decade so its 1548 use is expected to be extremely rare. 1549 155020121223: 1551 After switching to Clang as the default compiler some users of ZFS 1552 on i386 systems started to experience stack overflow kernel panics. 1553 Please consider using 'options KSTACK_PAGES=4' in such configurations. 1554 155520121222: 1556 GEOM_LABEL now mangles label names read from file system metadata. 1557 Mangling affect labels containing spaces, non-printable characters, 1558 '%' or '"'. Device names in /etc/fstab and other places may need to 1559 be updated. 1560 156120121217: 1562 By default, only the 10 most recent kernel dumps will be saved. To 1563 restore the previous behaviour (no limit on the number of kernel dumps 1564 stored in the dump directory) add the following line to /etc/rc.conf: 1565 1566 savecore_flags="" 1567 156820121201: 1569 With the addition of auditdistd(8), a new auditdistd user is now 1570 required during installworld. "mergemaster -p" can be used to 1571 add the user prior to installworld, as documented in the handbook. 1572 157320121117: 1574 The sin6_scope_id member variable in struct sockaddr_in6 is now 1575 filled by the kernel before passing the structure to the userland via 1576 sysctl or routing socket. This means the KAME-specific embedded scope 1577 id in sin6_addr.s6_addr[2] is always cleared in userland application. 1578 This behavior can be controlled by net.inet6.ip6.deembed_scopeid. 1579 __FreeBSD_version is bumped to 1000025. 1580 158120121105: 1582 On i386 and amd64 systems WITH_CLANG_IS_CC is now the default. 1583 This means that the world and kernel will be compiled with clang 1584 and that clang will be installed as /usr/bin/cc, /usr/bin/c++, 1585 and /usr/bin/cpp. To disable this behavior and revert to building 1586 with gcc, compile with WITHOUT_CLANG_IS_CC. Really old versions 1587 of current may need to bootstrap WITHOUT_CLANG first if the clang 1588 build fails (its compatibility window doesn't extend to the 9 stable 1589 branch point). 1590 159120121102: 1592 The IPFIREWALL_FORWARD kernel option has been removed. Its 1593 functionality now turned on by default. 1594 159520121023: 1596 The ZERO_COPY_SOCKET kernel option has been removed and 1597 split into SOCKET_SEND_COW and SOCKET_RECV_PFLIP. 1598 NB: SOCKET_SEND_COW uses the VM page based copy-on-write 1599 mechanism which is not safe and may result in kernel crashes. 1600 NB: The SOCKET_RECV_PFLIP mechanism is useless as no current 1601 driver supports disposeable external page sized mbuf storage. 1602 Proper replacements for both zero-copy mechanisms are under 1603 consideration and will eventually lead to complete removal 1604 of the two kernel options. 1605 160620121023: 1607 The IPv4 network stack has been converted to network byte 1608 order. The following modules need to be recompiled together 1609 with kernel: carp(4), divert(4), gif(4), siftr(4), gre(4), 1610 pf(4), ipfw(4), ng_ipfw(4), stf(4). 1611 161220121022: 1613 Support for non-MPSAFE filesystems was removed from VFS. The 1614 VFS_VERSION was bumped, all filesystem modules shall be 1615 recompiled. 1616 161720121018: 1618 All the non-MPSAFE filesystems have been disconnected from 1619 the build. The full list includes: codafs, hpfs, ntfs, nwfs, 1620 portalfs, smbfs, xfs. 1621 162220121016: 1623 The interface cloning API and ABI has changed. The following 1624 modules need to be recompiled together with kernel: 1625 ipfw(4), pfsync(4), pflog(4), usb(4), wlan(4), stf(4), 1626 vlan(4), disc(4), edsc(4), if_bridge(4), gif(4), tap(4), 1627 faith(4), epair(4), enc(4), tun(4), if_lagg(4), gre(4). 1628 162920121015: 1630 The sdhci driver was split in two parts: sdhci (generic SD Host 1631 Controller logic) and sdhci_pci (actual hardware driver). 1632 No kernel config modifications are required, but if you 1633 load sdhc as a module you must switch to sdhci_pci instead. 1634 163520121014: 1636 Import the FUSE kernel and userland support into base system. 1637 163820121013: 1639 The GNU sort(1) program has been removed since the BSD-licensed 1640 sort(1) has been the default for quite some time and no serious 1641 problems have been reported. The corresponding WITH_GNU_SORT 1642 knob has also gone. 1643 164420121006: 1645 The pfil(9) API/ABI for AF_INET family has been changed. Packet 1646 filtering modules: pf(4), ipfw(4), ipfilter(4) need to be recompiled 1647 with new kernel. 1648 164920121001: 1650 The net80211(4) ABI has been changed to allow for improved driver 1651 PS-POLL and power-save support. All wireless drivers need to be 1652 recompiled to work with the new kernel. 1653 165420120913: 1655 The random(4) support for the VIA hardware random number 1656 generator (`PADLOCK') is no longer enabled unconditionally. 1657 Add the padlock_rng device in the custom kernel config if 1658 needed. The GENERIC kernels on i386 and amd64 do include the 1659 device, so the change only affects the custom kernel 1660 configurations. 1661 166220120908: 1663 The pf(4) packet filter ABI has been changed. pfctl(8) and 1664 snmp_pf module need to be recompiled to work with new kernel. 1665 166620120828: 1667 A new ZFS feature flag "com.delphix:empty_bpobj" has been merged 1668 to -HEAD. Pools that have empty_bpobj in active state can not be 1669 imported read-write with ZFS implementations that do not support 1670 this feature. For more information read the zpool-features(5) 1671 manual page. 1672 167320120727: 1674 The sparc64 ZFS loader has been changed to no longer try to auto- 1675 detect ZFS providers based on diskN aliases but now requires these 1676 to be explicitly listed in the OFW boot-device environment variable. 1677 167820120712: 1679 The OpenSSL has been upgraded to 1.0.1c. Any binaries requiring 1680 libcrypto.so.6 or libssl.so.6 must be recompiled. Also, there are 1681 configuration changes. Make sure to merge /etc/ssl/openssl.cnf. 1682 168320120712: 1684 The following sysctls and tunables have been renamed for consistency 1685 with other variables: 1686 kern.cam.da.da_send_ordered -> kern.cam.da.send_ordered 1687 kern.cam.ada.ada_send_ordered -> kern.cam.ada.send_ordered 1688 168920120628: 1690 The sort utility has been replaced with BSD sort. For now, GNU sort 1691 is also available as "gnusort" or the default can be set back to 1692 GNU sort by setting WITH_GNU_SORT. In this case, BSD sort will be 1693 installed as "bsdsort". 1694 169520120611: 1696 A new version of ZFS (pool version 5000) has been merged to -HEAD. 1697 Starting with this version the old system of ZFS pool versioning 1698 is superseded by "feature flags". This concept enables forward 1699 compatibility against certain future changes in functionality of ZFS 1700 pools. The first read-only compatible "feature flag" for ZFS pools 1701 is named "com.delphix:async_destroy". For more information 1702 read the new zpool-features(5) manual page. 1703 Please refer to the "ZFS notes" section of this file for information 1704 on upgrading boot ZFS pools. 1705 170620120417: 1707 The malloc(3) implementation embedded in libc now uses sources imported 1708 as contrib/jemalloc. The most disruptive API change is to 1709 /etc/malloc.conf. If your system has an old-style /etc/malloc.conf, 1710 delete it prior to installworld, and optionally re-create it using the 1711 new format after rebooting. See malloc.conf(5) for details 1712 (specifically the TUNING section and the "opt.*" entries in the MALLCTL 1713 NAMESPACE section). 1714 171520120328: 1716 Big-endian MIPS TARGET_ARCH values no longer end in "eb". mips64eb 1717 is now spelled mips64. mipsn32eb is now spelled mipsn32. mipseb is 1718 now spelled mips. This is to aid compatibility with third-party 1719 software that expects this naming scheme in uname(3). Little-endian 1720 settings are unchanged. If you are updating a big-endian mips64 machine 1721 from before this change, you may need to set MACHINE_ARCH=mips64 in 1722 your environment before the new build system will recognize your machine. 1723 172420120306: 1725 Disable by default the option VFS_ALLOW_NONMPSAFE for all supported 1726 platforms. 1727 172820120229: 1729 Now unix domain sockets behave "as expected" on nullfs(5). Previously 1730 nullfs(5) did not pass through all behaviours to the underlying layer, 1731 as a result if we bound to a socket on the lower layer we could connect 1732 only to the lower path; if we bound to the upper layer we could connect 1733 only to the upper path. The new behavior is one can connect to both the 1734 lower and the upper paths regardless what layer path one binds to. 1735 173620120211: 1737 The getifaddrs upgrade path broken with 20111215 has been restored. 1738 If you have upgraded in between 20111215 and 20120209 you need to 1739 recompile libc again with your kernel. You still need to recompile 1740 world to be able to configure CARP but this restriction already 1741 comes from 20111215. 1742 174320120114: 1744 The set_rcvar() function has been removed from /etc/rc.subr. All 1745 base and ports rc.d scripts have been updated, so if you have a 1746 port installed with a script in /usr/local/etc/rc.d you can either 1747 hand-edit the rcvar= line, or reinstall the port. 1748 1749 An easy way to handle the mass-update of /etc/rc.d: 1750 rm /etc/rc.d/* && mergemaster -i 1751 175220120109: 1753 panic(9) now stops other CPUs in the SMP systems, disables interrupts 1754 on the current CPU and prevents other threads from running. 1755 This behavior can be reverted using the kern.stop_scheduler_on_panic 1756 tunable/sysctl. 1757 The new behavior can be incompatible with kern.sync_on_panic. 1758 175920111215: 1760 The carp(4) facility has been changed significantly. Configuration 1761 of the CARP protocol via ifconfig(8) has changed, as well as format 1762 of CARP events submitted to devd(8) has changed. See manual pages 1763 for more information. The arpbalance feature of carp(4) is currently 1764 not supported anymore. 1765 1766 Size of struct in_aliasreq, struct in6_aliasreq has changed. User 1767 utilities using SIOCAIFADDR, SIOCAIFADDR_IN6, e.g. ifconfig(8), 1768 need to be recompiled. 1769 177020111122: 1771 The acpi_wmi(4) status device /dev/wmistat has been renamed to 1772 /dev/wmistat0. 1773 177420111108: 1775 The option VFS_ALLOW_NONMPSAFE option has been added in order to 1776 explicitely support non-MPSAFE filesystems. 1777 It is on by default for all supported platform at this present 1778 time. 1779 178020111101: 1781 The broken amd(4) driver has been replaced with esp(4) in the amd64, 1782 i386 and pc98 GENERIC kernel configuration files. 1783 178420110930: 1785 sysinstall has been removed 1786 178720110923: 1788 The stable/9 branch created in subversion. This corresponds to the 1789 RELENG_9 branch in CVS. 1790 1791COMMON ITEMS: 1792 1793 General Notes 1794 ------------- 1795 Avoid using make -j when upgrading. While generally safe, there are 1796 sometimes problems using -j to upgrade. If your upgrade fails with 1797 -j, please try again without -j. From time to time in the past there 1798 have been problems using -j with buildworld and/or installworld. This 1799 is especially true when upgrading between "distant" versions (eg one 1800 that cross a major release boundary or several minor releases, or when 1801 several months have passed on the -current branch). 1802 1803 Sometimes, obscure build problems are the result of environment 1804 poisoning. This can happen because the make utility reads its 1805 environment when searching for values for global variables. To run 1806 your build attempts in an "environmental clean room", prefix all make 1807 commands with 'env -i '. See the env(1) manual page for more details. 1808 1809 When upgrading from one major version to another it is generally best to 1810 upgrade to the latest code in the currently installed branch first, then 1811 do an upgrade to the new branch. This is the best-tested upgrade path, 1812 and has the highest probability of being successful. Please try this 1813 approach if you encounter problems with a major version upgrade. Since 1814 the stable 4.x branch point, one has generally been able to upgade from 1815 anywhere in the most recent stable branch to head / current (or even the 1816 last couple of stable branches). See the top of this file when there's 1817 an exception. 1818 1819 When upgrading a live system, having a root shell around before 1820 installing anything can help undo problems. Not having a root shell 1821 around can lead to problems if pam has changed too much from your 1822 starting point to allow continued authentication after the upgrade. 1823 1824 This file should be read as a log of events. When a later event changes 1825 information of a prior event, the prior event should not be deleted. 1826 Instead, a pointer to the entry with the new information should be 1827 placed in the old entry. Readers of this file should also sanity check 1828 older entries before relying on them blindly. Authors of new entries 1829 should write them with this in mind. 1830 1831 ZFS notes 1832 --------- 1833 When upgrading the boot ZFS pool to a new version, always follow 1834 these two steps: 1835 1836 1.) recompile and reinstall the ZFS boot loader and boot block 1837 (this is part of "make buildworld" and "make installworld") 1838 1839 2.) update the ZFS boot block on your boot drive 1840 1841 The following example updates the ZFS boot block on the first 1842 partition (freebsd-boot) of a GPT partitioned drive ada0: 1843 "gpart bootcode -p /boot/gptzfsboot -i 1 ada0" 1844 1845 Non-boot pools do not need these updates. 1846 1847 To build a kernel 1848 ----------------- 1849 If you are updating from a prior version of FreeBSD (even one just 1850 a few days old), you should follow this procedure. It is the most 1851 failsafe as it uses a /usr/obj tree with a fresh mini-buildworld, 1852 1853 make kernel-toolchain 1854 make -DALWAYS_CHECK_MAKE buildkernel KERNCONF=YOUR_KERNEL_HERE 1855 make -DALWAYS_CHECK_MAKE installkernel KERNCONF=YOUR_KERNEL_HERE 1856 1857 To test a kernel once 1858 --------------------- 1859 If you just want to boot a kernel once (because you are not sure 1860 if it works, or if you want to boot a known bad kernel to provide 1861 debugging information) run 1862 make installkernel KERNCONF=YOUR_KERNEL_HERE KODIR=/boot/testkernel 1863 nextboot -k testkernel 1864 1865 To rebuild everything and install it on the current system. 1866 ----------------------------------------------------------- 1867 # Note: sometimes if you are running current you gotta do more than 1868 # is listed here if you are upgrading from a really old current. 1869 1870 <make sure you have good level 0 dumps> 1871 make buildworld 1872 make buildkernel KERNCONF=YOUR_KERNEL_HERE 1873 make installkernel KERNCONF=YOUR_KERNEL_HERE 1874 [1] 1875 <reboot in single user> [3] 1876 mergemaster -Fp [5] 1877 make installworld 1878 mergemaster -Fi [4] 1879 make delete-old [6] 1880 <reboot> 1881 1882 To cross-install current onto a separate partition 1883 -------------------------------------------------- 1884 # In this approach we use a separate partition to hold 1885 # current's root, 'usr', and 'var' directories. A partition 1886 # holding "/", "/usr" and "/var" should be about 2GB in 1887 # size. 1888 1889 <make sure you have good level 0 dumps> 1890 <boot into -stable> 1891 make buildworld 1892 make buildkernel KERNCONF=YOUR_KERNEL_HERE 1893 <maybe newfs current's root partition> 1894 <mount current's root partition on directory ${CURRENT_ROOT}> 1895 make installworld DESTDIR=${CURRENT_ROOT} -DDB_FROM_SRC 1896 make distribution DESTDIR=${CURRENT_ROOT} # if newfs'd 1897 make installkernel KERNCONF=YOUR_KERNEL_HERE DESTDIR=${CURRENT_ROOT} 1898 cp /etc/fstab ${CURRENT_ROOT}/etc/fstab # if newfs'd 1899 <edit ${CURRENT_ROOT}/etc/fstab to mount "/" from the correct partition> 1900 <reboot into current> 1901 <do a "native" rebuild/install as described in the previous section> 1902 <maybe install compatibility libraries from ports/misc/compat*> 1903 <reboot> 1904 1905 1906 To upgrade in-place from stable to current 1907 ---------------------------------------------- 1908 <make sure you have good level 0 dumps> 1909 make buildworld [9] 1910 make kernel KERNCONF=YOUR_KERNEL_HERE [8] 1911 [1] 1912 <reboot in single user> [3] 1913 mergemaster -Fp [5] 1914 make installworld 1915 mergemaster -Fi [4] 1916 make delete-old [6] 1917 <reboot> 1918 1919 Make sure that you've read the UPDATING file to understand the 1920 tweaks to various things you need. At this point in the life 1921 cycle of current, things change often and you are on your own 1922 to cope. The defaults can also change, so please read ALL of 1923 the UPDATING entries. 1924 1925 Also, if you are tracking -current, you must be subscribed to 1926 freebsd-current@freebsd.org. Make sure that before you update 1927 your sources that you have read and understood all the recent 1928 messages there. If in doubt, please track -stable which has 1929 much fewer pitfalls. 1930 1931 [1] If you have third party modules, such as vmware, you 1932 should disable them at this point so they don't crash your 1933 system on reboot. 1934 1935 [3] From the bootblocks, boot -s, and then do 1936 fsck -p 1937 mount -u / 1938 mount -a 1939 cd src 1940 adjkerntz -i # if CMOS is wall time 1941 Also, when doing a major release upgrade, it is required that 1942 you boot into single user mode to do the installworld. 1943 1944 [4] Note: This step is non-optional. Failure to do this step 1945 can result in a significant reduction in the functionality of the 1946 system. Attempting to do it by hand is not recommended and those 1947 that pursue this avenue should read this file carefully, as well 1948 as the archives of freebsd-current and freebsd-hackers mailing lists 1949 for potential gotchas. The -U option is also useful to consider. 1950 See mergemaster(8) for more information. 1951 1952 [5] Usually this step is a noop. However, from time to time 1953 you may need to do this if you get unknown user in the following 1954 step. It never hurts to do it all the time. You may need to 1955 install a new mergemaster (cd src/usr.sbin/mergemaster && make 1956 install) after the buildworld before this step if you last updated 1957 from current before 20130425 or from -stable before 20130430. 1958 1959 [6] This only deletes old files and directories. Old libraries 1960 can be deleted by "make delete-old-libs", but you have to make 1961 sure that no program is using those libraries anymore. 1962 1963 [8] In order to have a kernel that can run the 4.x binaries needed to 1964 do an installworld, you must include the COMPAT_FREEBSD4 option in 1965 your kernel. Failure to do so may leave you with a system that is 1966 hard to boot to recover. A similar kernel option COMPAT_FREEBSD5 is 1967 required to run the 5.x binaries on more recent kernels. And so on 1968 for COMPAT_FREEBSD6 and COMPAT_FREEBSD7. 1969 1970 Make sure that you merge any new devices from GENERIC since the 1971 last time you updated your kernel config file. 1972 1973 [9] If CPUTYPE is defined in your /etc/make.conf, make sure to use the 1974 "?=" instead of the "=" assignment operator, so that buildworld can 1975 override the CPUTYPE if it needs to. 1976 1977 MAKEOBJDIRPREFIX must be defined in an environment variable, and 1978 not on the command line, or in /etc/make.conf. buildworld will 1979 warn if it is improperly defined. 1980FORMAT: 1981 1982This file contains a list, in reverse chronological order, of major 1983breakages in tracking -current. It is not guaranteed to be a complete 1984list of such breakages, and only contains entries since September 23, 2011. 1985If you need to see UPDATING entries from before that date, you will need 1986to fetch an UPDATING file from an older FreeBSD release. 1987 1988Copyright information: 1989 1990Copyright 1998-2009 M.
