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 5420180319: 55 For UEFI systems: the UEFI loader(8), loader.efi, should be updated in 56 conjunction with installing a new kernel after r330868. The kernel, 57 after this revision, will be more lenient when mapping addresses for 58 UEFI Runtime Services and this may result in a kernel panic without the 59 corresponding loader(8) update. 60 6120180212: 62 FreeBSD boot loader enhanced with Lua scripting. It's purely opt-in for 63 now by building WITH_LOADER_LUA and WITHOUT_FORTH in /etc/src.conf. 64 Co-existance for the transition period will come shortly. Booting is a 65 complex environment and test coverage for Lua-enabled loaders has been 66 thin, so it would be prudent to assume it might not work and make 67 provisions for backup boot methods. 68 6920180211: 70 devmatch functionality has been turned on in devd. It will automatically 71 load drivers for unattached devices. This may cause unexpected drivers to 72 be loaded. Please report any problems to current@ and imp@freebsd.org. 73 7420180114: 75 Clang, llvm, lld, lldb, compiler-rt and libc++ have been upgraded to 76 6.0.0. Please see the 20141231 entry below for information about 77 prerequisites and upgrading, if you are not already using clang 3.5.0 78 or higher. 79 8020180110: 81 LLVM's lld linker is now used as the FreeBSD/amd64 bootstrap linker. 82 This means it is used to link the kernel and userland libraries and 83 executables, but is not yet installed as /usr/bin/ld by default. 84 85 To revert to ld.bfd as the bootstrap linker, in /etc/src.conf set 86 WITHOUT_LLD_BOOTSTRAP=yes 87 8820180110: 89 On i386, pmtimer has been removed. Its functionality has been folded 90 into apm. It was a no-op on ACPI in current for a while now (but was still 91 needed on i386 in FreeBSD 11 and earlier). Users may need to remove it 92 from kernel config files. 93 9420180104: 95 The use of RSS hash from the network card aka flowid has been 96 disabled by default for lagg(4) as it's currently incompatible with 97 the lacp and loadbalance protocols. 98 99 This can be re-enabled by setting the following in loader.conf: 100 net.link.lagg.default_use_flowid="1" 101 10220180102: 103 The SW_WATCHDOG option is no longer necessary to enable the 104 hardclock-based software watchdog if no hardware watchdog is 105 configured. As before, SW_WATCHDOG will cause the software 106 watchdog to be enabled even if a hardware watchdog is configured. 107 10820171215: 109 r326887 fixes the issue described in the 20171214 UPDATING entry. 110 r326888 flips the switch back to building GELI support always. 111 11220171214: 113 r362593 broke ZFS + GELI support for reasons unknown. However, 114 it also broke ZFS support generally, so GELI has been turned off 115 by default as the lesser evil in r326857. If you boot off ZFS and/or 116 GELI, it might not be a good time to update. 117 11820171125: 119 PowerPC users must update loader(8) by rebuilding world before 120 installing a new kernel, as the protocol connecting them has 121 changed. Without the update, loader metadata will not be passed 122 successfully to the kernel and users will have to enter their 123 root partition at the kernel mountroot prompt to continue booting. 124 Newer versions of loader can boot old kernels without issue. 125 12620171110: 127 The LOADER_FIREWIRE_SUPPORT build variable as been renamed to 128 WITH/OUT_LOADER_FIREWIRE. LOADER_{NO_,}GELI_SUPPORT has been renamed 129 to WITH/OUT_LOADER_GELI. 130 13120171106: 132 The naive and non-compliant support of posix_fallocate(2) in ZFS 133 has been removed as of r325320. The system call now returns EINVAL 134 when used on a ZFS file. Although the new behavior complies with the 135 standard, some consumers are not prepared to cope with it. 136 One known victim is lld prior to r325420. 137 13820171102: 139 Building in a FreeBSD src checkout will automatically create object 140 directories now rather than store files in the current directory if 141 'make obj' was not ran. Calling 'make obj' is no longer necessary. 142 This feature can be disabled by setting WITHOUT_AUTO_OBJ=yes in 143 /etc/src-env.conf (not /etc/src.conf), or passing the option in the 144 environment. 145 14620171101: 147 The default MAKEOBJDIR has changed from /usr/obj/<srcdir> for native 148 builds, and /usr/obj/<arch>/<srcdir> for cross-builds, to a unified 149 /usr/obj/<srcdir>/<arch>. This behavior can be changed to the old 150 format by setting WITHOUT_UNIFIED_OBJDIR=yes in /etc/src-env.conf, 151 the environment, or with -DWITHOUT_UNIFIED_OBJDIR when building. 152 The UNIFIED_OBJDIR option is a transitional feature that will be 153 removed for 12.0 release; please migrate to the new format for any 154 tools by looking up the OBJDIR used by 'make -V .OBJDIR' means rather 155 than hardcoding paths. 156 15720171028: 158 The native-xtools target no longer installs the files by default to the 159 OBJDIR. Use the native-xtools-install target with a DESTDIR to install 160 to ${DESTDIR}/${NXTP} where NXTP defaults to /nxb-bin. 161 16220171021: 163 As part of the boot loader infrastructure cleanup, LOADER_*_SUPPORT 164 options are changing from controlling the build if defined / undefined 165 to controlling the build with explicit 'yes' or 'no' values. They will 166 shift to WITH/WITHOUT options to match other options in the system. 167 16820171010: 169 libstand has turned into a private library for sys/boot use only. 170 It is no longer supported as a public interface outside of sys/boot. 171 17220171005: 173 The arm port has split armv6 into armv6 and armv7. armv7 is now 174 a valid TARGET_ARCH/MACHINE_ARCH setting. If you have an armv7 system 175 and are running a kernel from before r324363, you will need to add 176 MACHINE_ARCH=armv7 to 'make buildworld' to do a native build. 177 17820171003: 179 When building multiple kernels using KERNCONF, non-existent KERNCONF 180 files will produce an error and buildkernel will fail. Previously 181 missing KERNCONF files silently failed giving no indication as to 182 why, only to subsequently discover during installkernel that the 183 desired kernel was never built in the first place. 184 18520170912: 186 The default serial number format for CTL LUNs has changed. This will 187 affect users who use /dev/diskid/* device nodes, or whose FibreChannel 188 or iSCSI clients care about their LUNs' serial numbers. Users who 189 require serial number stability should hardcode serial numbers in 190 /etc/ctl.conf . 191 19220170912: 193 For 32-bit arm compiled for hard-float support, soft-floating point 194 binaries now always get their shared libraries from 195 LD_SOFT_LIBRARY_PATH (in the past, this was only used if 196 /usr/libsoft also existed). Only users with a hard-float ld.so, but 197 soft-float everything else should be affected. 198 19920170826: 200 The geli password typed at boot is now hidden. To restore the previous 201 behavior, see geli(8) for configuration options. 202 20320170825: 204 Move PMTUD blackhole counters to TCPSTATS and remove them from bare 205 sysctl values. Minor nit, but requires a rebuild of both world/kernel 206 to complete. 207 20820170814: 209 "make check" behavior (made in ^/head@r295380) has been changed to 210 execute from a limited sandbox, as opposed to executing from 211 ${TESTSDIR}. 212 213 Behavioral changes: 214 - The "beforecheck" and "aftercheck" targets are now specified. 215 - ${CHECKDIR} (added in commit noted above) has been removed. 216 - Legacy behavior can be enabled by setting 217 WITHOUT_MAKE_CHECK_USE_SANDBOX in src.conf(5) or the environment. 218 219 If the limited sandbox mode is enabled, "make check" will execute 220 "make distribution", then install, execute the tests, and clean up the 221 sandbox if successful. 222 223 The "make distribution" and "make install" targets are typically run as 224 root to set appropriate permissions and ownership at installation time. 225 The end-user should set "WITH_INSTALL_AS_USER" in src.conf(5) or the 226 environment if executing "make check" with limited sandbox mode using 227 an unprivileged user. 228 22920170808: 230 Since the switch to GPT disk labels, fsck for UFS/FFS has been 231 unable to automatically find alternate superblocks. As of r322297, 232 the information needed to find alternate superblocks has been 233 moved to the end of the area reserved for the boot block. 234 Filesystems created with a newfs of this vintage or later 235 will create the recovery information. If you have a filesystem 236 created prior to this change and wish to have a recovery block 237 created for your filesystem, you can do so by running fsck in 238 foreground mode (i.e., do not use the -p or -y options). As it 239 starts, fsck will ask ``SAVE DATA TO FIND ALTERNATE SUPERBLOCKS'' 240 to which you should answer yes. 241 24220170728: 243 As of r321665, an NFSv4 server configuration that services 244 Kerberos mounts or clients that do not support the uid/gid in 245 owner/owner_group string capability, must explicitly enable 246 the nfsuserd daemon by adding nfsuserd_enable="YES" to the 247 machine's /etc/rc.conf file. 248 24920170722: 250 Clang, llvm, lldb, compiler-rt and libc++ have been upgraded to 5.0.0. 251 Please see the 20141231 entry below for information about prerequisites 252 and upgrading, if you are not already using clang 3.5.0 or higher. 253 25420170701: 255 WITHOUT_RCMDS is now the default. Set WITH_RCMDS if you need the 256 r-commands (rlogin, rsh, etc.) to be built with the base system. 257 25820170625: 259 The FreeBSD/powerpc platform now uses a 64-bit type for time_t. This is 260 a very major ABI incompatible change, so users of FreeBSD/powerpc must 261 be careful when performing source upgrades. It is best to run 262 'make installworld' from an alternate root system, either a live 263 CD/memory stick, or a temporary root partition. Additionally, all ports 264 must be recompiled. powerpc64 is largely unaffected, except in the case 265 of 32-bit compatibility. All 32-bit binaries will be affected. 266 26720170623: 268 Forward compatibility for the "ino64" project have been committed. This 269 will allow most new binaries to run on older kernels in a limited 270 fashion. This prevents many of the common foot-shooting actions in the 271 upgrade as well as the limited ability to roll back the kernel across 272 the ino64 upgrade. Complicated use cases may not work properly, though 273 enough simpler ones work to allow recovery in most situations. 274 27520170620: 276 Switch back to the BSDL dtc (Device Tree Compiler). Set WITH_GPL_DTC 277 if you require the GPL compiler. 278 27920170618: 280 The internal ABI used for communication between the NFS kernel modules 281 was changed by r320085, so __FreeBSD_version was bumped to 282 ensure all the NFS related modules are updated together. 283 28420170617: 285 The ABI of struct event was changed by extending the data 286 member to 64bit and adding ext fields. For upgrade, same 287 precautions as for the entry 20170523 "ino64" must be 288 followed. 289 29020170531: 291 The GNU roff toolchain has been removed from base. To render manpages 292 which are not supported by mandoc(1), man(1) can fallback on GNU roff 293 from ports (and recommends to install it). 294 To render roff(7) documents, consider using GNU roff from ports or the 295 heirloom doctools roff toolchain from ports via pkg install groff or 296 via pkg install heirloom-doctools. 297 29820170524: 299 The ath(4) and ath_hal(4) modules now build piecemeal to allow for 300 smaller runtime footprint builds. This is useful for embedded systems 301 which only require one chipset support. 302 303 If you load it as a module, make sure this is in /boot/loader.conf: 304 305 if_ath_load="YES" 306 307 This will load the HAL, all chip/RF backends and if_ath_pci. 308 If you have if_ath_pci in /boot/loader.conf, ensure it is after 309 if_ath or it will not load any HAL chipset support. 310 311 If you want to selectively load things (eg on ye cheape ARM/MIPS 312 platforms where RAM is at a premium) you should: 313 314 * load ath_hal 315 * load the chip modules in question 316 * load ath_rate, ath_dfs 317 * load ath_main 318 * load if_ath_pci and/or if_ath_ahb depending upon your particular 319 bus bind type - this is where probe/attach is done. 320 321 For further comments/feedback, poke adrian@ . 322 32320170523: 324 The "ino64" 64-bit inode project has been committed, which extends 325 a number of types to 64 bits. Upgrading in place requires care and 326 adherence to the documented upgrade procedure. 327 328 If using a custom kernel configuration ensure that the 329 COMPAT_FREEBSD11 option is included (as during the upgrade the 330 system will be running the ino64 kernel with the existing world). 331 332 For the safest in-place upgrade begin by removing previous build 333 artifacts via "rm -rf /usr/obj/*". Then, carefully follow the 334 full procedure documented below under the heading "To rebuild 335 everything and install it on the current system." Specifically, 336 a reboot is required after installing the new kernel before 337 installing world. 338 33920170424: 340 The NATM framework including the en(4), fatm(4), hatm(4), and 341 patm(4) devices has been removed. Consumers should plan a 342 migration before the end-of-life date for FreeBSD 11. 343 34420170420: 345 GNU diff has been replaced by a BSD licensed diff. Some features of GNU 346 diff has not been implemented, if those are needed a newer version of 347 GNU diff is available via the diffutils package under the gdiff name. 348 34920170413: 350 As of r316810 for ipfilter, keep frags is no longer assumed when 351 keep state is specified in a rule. r316810 aligns ipfilter with 352 documentation in man pages separating keep frags from keep state. 353 This allows keep state to be specified without forcing keep frags 354 and allows keep frags to be specified independently of keep state. 355 To maintain previous behaviour, also specify keep frags with 356 keep state (as documented in ipf.conf.5). 357 35820170407: 359 arm64 builds now use the base system LLD 4.0.0 linker by default, 360 instead of requiring that the aarch64-binutils port or package be 361 installed. To continue using aarch64-binutils, set 362 CROSS_BINUTILS_PREFIX=/usr/local/aarch64-freebsd/bin . 363 36420170405: 365 The UDP optimization in entry 20160818 that added the sysctl 366 net.inet.udp.require_l2_bcast has been reverted. L2 broadcast 367 packets will no longer be treated as L3 broadcast packets. 368 36920170331: 370 Binds and sends to the loopback addresses, IPv6 and IPv4, will now 371 use any explicitly assigned loopback address available in the jail 372 instead of using the first assigned address of the jail. 373 37420170329: 375 The ctl.ko module no longer implements the iSCSI target frontend: 376 cfiscsi.ko does instead. 377 378 If building cfiscsi.ko as a kernel module, the module can be loaded 379 via one of the following methods: 380 - `cfiscsi_load="YES"` in loader.conf(5). 381 - Add `cfiscsi` to `$kld_list` in rc.conf(5). 382 - ctladm(8)/ctld(8), when compiled with iSCSI support 383 (`WITH_ISCSI=yes` in src.conf(5)) 384 385 Please see cfiscsi(4) for more details. 386 38720170316: 388 The mmcsd.ko module now additionally depends on geom_flashmap.ko. 389 Also, mmc.ko and mmcsd.ko need to be a matching pair built from the 390 same source (previously, the dependency of mmcsd.ko on mmc.ko was 391 missing, but mmcsd.ko now will refuse to load if it is incompatible 392 with mmc.ko). 393 39420170315: 395 The syntax of ipfw(8) named states was changed to avoid ambiguity. 396 If you have used named states in the firewall rules, you need to modify 397 them after installworld and before rebooting. Now named states must 398 be prefixed with colon. 399 40020170311: 401 The old drm (sys/dev/drm/) drivers for i915 and radeon have been 402 removed as the userland we provide cannot use them. The KMS version 403 (sys/dev/drm2) supports the same hardware. 404 40520170302: 406 Clang, llvm, lldb, compiler-rt and libc++ have been upgraded to 4.0.0. 407 Please see the 20141231 entry below for information about prerequisites 408 and upgrading, if you are not already using clang 3.5.0 or higher. 409 41020170221: 411 The code that provides support for ZFS .zfs/ directory functionality 412 has been reimplemented. It's not possible now to create a snapshot 413 by mkdir under .zfs/snapshot/. That should be the only user visible 414 change. 415 41620170216: 417 EISA bus support has been removed. The WITH_EISA option is no longer 418 valid. 419 42020170215: 421 MCA bus support has been removed. 422 42320170127: 424 The WITH_LLD_AS_LD / WITHOUT_LLD_AS_LD build knobs have been renamed 425 WITH_LLD_IS_LD / WITHOUT_LLD_IS_LD, for consistency with CLANG_IS_CC. 426 42720170112: 428 The EM_MULTIQUEUE kernel configuration option is deprecated now that 429 the em(4) driver conforms to iflib specifications. 430 43120170109: 432 The igb(4), em(4) and lem(4) ethernet drivers are now implemented via 433 IFLIB. If you have a custom kernel configuration that excludes em(4) 434 but you use igb(4), you need to re-add em(4) to your custom configuration. 435 43620161217: 437 Clang, llvm, lldb, compiler-rt and libc++ have been upgraded to 3.9.1. 438 Please see the 20141231 entry below for information about prerequisites 439 and upgrading, if you are not already using clang 3.5.0 or higher. 440 44120161124: 442 Clang, llvm, lldb, compiler-rt and libc++ have been upgraded to 3.9.0. 443 Please see the 20141231 entry below for information about prerequisites 444 and upgrading, if you are not already using clang 3.5.0 or higher. 445 44620161119: 447 The layout of the pmap structure has changed for powerpc to put the pmap 448 statistics at the front for all CPU variations. libkvm(3) and all tools 449 that link against it need to be recompiled. 450 45120161030: 452 isl(4) and cyapa(4) drivers now require a new driver, 453 chromebook_platform(4), to work properly on Chromebook-class hardware. 454 On other types of hardware the drivers may need to be configured using 455 device hints. Please see the corresponding manual pages for details. 456 45720161017: 458 The urtwn(4) driver was merged into rtwn(4) and now consists of 459 rtwn(4) main module + rtwn_usb(4) and rtwn_pci(4) bus-specific 460 parts. 461 Also, firmware for RTL8188CE was renamed due to possible name 462 conflict (rtwnrtl8192cU(B) -> rtwnrtl8192cE(B)) 463 46420161015: 465 GNU rcs has been removed from base. It is available as packages: 466 - rcs: Latest GPLv3 GNU rcs version. 467 - rcs57: Copy of the latest version of GNU rcs (GPLv2) before it was 468 removed from base. 469 47020161008: 471 Use of the cc_cdg, cc_chd, cc_hd, or cc_vegas congestion control 472 modules now requires that the kernel configuration contain the 473 TCP_HHOOK option. (This option is included in the GENERIC kernel.) 474 47520161003: 476 The WITHOUT_ELFCOPY_AS_OBJCOPY src.conf(5) knob has been retired. 477 ELF Tool Chain's elfcopy is always installed as /usr/bin/objcopy. 478 47920160924: 480 Relocatable object files with the extension of .So have been renamed 481 to use an extension of .pico instead. The purpose of this change is 482 to avoid a name clash with shared libraries on case-insensitive file 483 systems. On those file systems, foo.So is the same file as foo.so. 484 48520160918: 486 GNU rcs has been turned off by default. It can (temporarily) be built 487 again by adding WITH_RCS knob in src.conf. 488 Otherwise, GNU rcs is available from packages: 489 - rcs: Latest GPLv3 GNU rcs version. 490 - rcs57: Copy of the latest version of GNU rcs (GPLv2) from base. 491 49220160918: 493 The backup_uses_rcs functionality has been removed from rc.subr. 494 49520160908: 496 The queue(3) debugging macro, QUEUE_MACRO_DEBUG, has been split into 497 two separate components, QUEUE_MACRO_DEBUG_TRACE and 498 QUEUE_MACRO_DEBUG_TRASH. Define both for the original 499 QUEUE_MACRO_DEBUG behavior. 500 50120160824: 502 r304787 changed some ioctl interfaces between the iSCSI userspace 503 programs and the kernel. ctladm, ctld, iscsictl, and iscsid must be 504 rebuilt to work with new kernels. __FreeBSD_version has been bumped 505 to 1200005. 506 50720160818: 508 The UDP receive code has been updated to only treat incoming UDP 509 packets that were addressed to an L2 broadcast address as L3 510 broadcast packets. It is not expected that this will affect any 511 standards-conforming UDP application. The new behaviour can be 512 disabled by setting the sysctl net.inet.udp.require_l2_bcast to 513 0. 514 51520160818: 516 Remove the openbsd_poll system call. 517 __FreeBSD_version has been bumped because of this. 518 51920160622: 520 The libc stub for the pipe(2) system call has been replaced with 521 a wrapper that calls the pipe2(2) system call and the pipe(2) 522 system call is now only implemented by the kernels that include 523 "options COMPAT_FREEBSD10" in their config file (this is the 524 default). Users should ensure that this option is enabled in 525 their kernel or upgrade userspace to r302092 before upgrading their 526 kernel. 527 52820160527: 529 CAM will now strip leading spaces from SCSI disks' serial numbers. 530 This will affect users who create UFS filesystems on SCSI disks using 531 those disk's diskid device nodes. For example, if /etc/fstab 532 previously contained a line like 533 "/dev/diskid/DISK-%20%20%20%20%20%20%20ABCDEFG0123456", you should 534 change it to "/dev/diskid/DISK-ABCDEFG0123456". Users of geom 535 transforms like gmirror may also be affected. ZFS users should 536 generally be fine. 537 53820160523: 539 The bitstring(3) API has been updated with new functionality and 540 improved performance. But it is binary-incompatible with the old API. 541 Objects built with the new headers may not be linked against objects 542 built with the old headers. 543 54420160520: 545 The brk and sbrk functions have been removed from libc on arm64. 546 Binutils from ports has been updated to not link to these 547 functions and should be updated to the latest version before 548 installing a new libc. 549 55020160517: 551 The armv6 port now defaults to hard float ABI. Limited support 552 for running both hardfloat and soft float on the same system 553 is available using the libraries installed with -DWITH_LIBSOFT. 554 This has only been tested as an upgrade path for installworld 555 and packages may fail or need manual intervention to run. New 556 packages will be needed. 557 558 To update an existing self-hosted armv6hf system, you must add 559 TARGET_ARCH=armv6 on the make command line for both the build 560 and the install steps. 561 56220160510: 563 Kernel modules compiled outside of a kernel build now default to 564 installing to /boot/modules instead of /boot/kernel. Many kernel 565 modules built this way (such as those in ports) already overrode 566 KMODDIR explicitly to install into /boot/modules. However, 567 manually building and installing a module from /sys/modules will 568 now install to /boot/modules instead of /boot/kernel. 569 57020160414: 571 The CAM I/O scheduler has been committed to the kernel. There should be 572 no user visible impact. This does enable NCQ Trim on ada SSDs. While the 573 list of known rogues that claim support for this but actually corrupt 574 data is believed to be complete, be on the lookout for data 575 corruption. The known rogue list is believed to be complete: 576 577 o Crucial MX100, M550 drives with MU01 firmware. 578 o Micron M510 and M550 drives with MU01 firmware. 579 o Micron M500 prior to MU07 firmware 580 o Samsung 830, 840, and 850 all firmwares 581 o FCCT M500 all firmwares 582 583 Crucial has firmware http://www.crucial.com/usa/en/support-ssd-firmware 584 with working NCQ TRIM. For Micron branded drives, see your sales rep for 585 updated firmware. Black listed drives will work correctly because these 586 drives work correctly so long as no NCQ TRIMs are sent to them. Given 587 this list is the same as found in Linux, it's believed there are no 588 other rogues in the market place. All other models from the above 589 vendors work. 590 591 To be safe, if you are at all concerned, you can quirk each of your 592 drives to prevent NCQ from being sent by setting: 593 kern.cam.ada.X.quirks="0x2" 594 in loader.conf. If the drive requires the 4k sector quirk, set the 595 quirks entry to 0x3. 596 59720160330: 598 The FAST_DEPEND build option has been removed and its functionality is 599 now the one true way. The old mkdep(1) style of 'make depend' has 600 been removed. See 20160311 for further details. 601 60220160317: 603 Resource range types have grown from unsigned long to uintmax_t. All 604 drivers, and anything using libdevinfo, need to be recompiled. 605 60620160311: 607 WITH_FAST_DEPEND is now enabled by default for in-tree and out-of-tree 608 builds. It no longer runs mkdep(1) during 'make depend', and the 609 'make depend' stage can safely be skipped now as it is auto ran 610 when building 'make all' and will generate all SRCS and DPSRCS before 611 building anything else. Dependencies are gathered at compile time with 612 -MF flags kept in separate .depend files per object file. Users should 613 run 'make cleandepend' once if using -DNO_CLEAN to clean out older 614 stale .depend files. 615 61620160306: 617 On amd64, clang 3.8.0 can now insert sections of type AMD64_UNWIND into 618 kernel modules. Therefore, if you load any kernel modules at boot time, 619 please install the boot loaders after you install the kernel, but before 620 rebooting, e.g.: 621 622 make buildworld 623 make kernel KERNCONF=YOUR_KERNEL_HERE 624 make -C sys/boot install 625 <reboot in single user> 626 627 Then follow the usual steps, described in the General Notes section, 628 below. 629 63020160305: 631 Clang, llvm, lldb and compiler-rt have been upgraded to 3.8.0. Please 632 see the 20141231 entry below for information about prerequisites and 633 upgrading, if you are not already using clang 3.5.0 or higher. 634 63520160301: 636 The AIO subsystem is now a standard part of the kernel. The 637 VFS_AIO kernel option and aio.ko kernel module have been removed. 638 Due to stability concerns, asynchronous I/O requests are only 639 permitted on sockets and raw disks by default. To enable 640 asynchronous I/O requests on all file types, set the 641 vfs.aio.enable_unsafe sysctl to a non-zero value. 642 64320160226: 644 The ELF object manipulation tool objcopy is now provided by the 645 ELF Tool Chain project rather than by GNU binutils. It should be a 646 drop-in replacement, with the addition of arm64 support. The 647 (temporary) src.conf knob WITHOUT_ELFCOPY_AS_OBJCOPY knob may be set 648 to obtain the GNU version if necessary. 649 65020160129: 651 Building ZFS pools on top of zvols is prohibited by default. That 652 feature has never worked safely; it's always been prone to deadlocks. 653 Using a zvol as the backing store for a VM guest's virtual disk will 654 still work, even if the guest is using ZFS. Legacy behavior can be 655 restored by setting vfs.zfs.vol.recursive=1. 656 65720160119: 658 The NONE and HPN patches has been removed from OpenSSH. They are 659 still available in the security/openssh-portable port. 660 66120160113: 662 With the addition of ypldap(8), a new _ypldap user is now required 663 during installworld. "mergemaster -p" can be used to add the user 664 prior to installworld, as documented in the handbook. 665 66620151216: 667 The tftp loader (pxeboot) now uses the option root-path directive. As a 668 consequence it no longer looks for a pxeboot.4th file on the tftp 669 server. Instead it uses the regular /boot infrastructure as with the 670 other loaders. 671 67220151211: 673 The code to start recording plug and play data into the modules has 674 been committed. While the old tools will properly build a new kernel, 675 a number of warnings about "unknown metadata record 4" will be produced 676 for an older kldxref. To avoid such warnings, make sure to rebuild 677 the kernel toolchain (or world). Make sure that you have r292078 or 678 later when trying to build 292077 or later before rebuilding. 679 68020151207: 681 Debug data files are now built by default with 'make buildworld' and 682 installed with 'make installworld'. This facilitates debugging but 683 requires more disk space both during the build and for the installed 684 world. Debug files may be disabled by setting WITHOUT_DEBUG_FILES=yes 685 in src.conf(5). 686 68720151130: 688 r291527 changed the internal interface between the nfsd.ko and 689 nfscommon.ko modules. As such, they must both be upgraded to-gether. 690 __FreeBSD_version has been bumped because of this. 691 69220151108: 693 Add support for unicode collation strings leads to a change of 694 order of files listed by ls(1) for example. To get back to the old 695 behaviour, set LC_COLLATE environment variable to "C". 696 697 Databases administrators will need to reindex their databases given 698 collation results will be different. 699 700 Due to a bug in install(1) it is recommended to remove the ancient 701 locales before running make installworld. 702 703 rm -rf /usr/share/locale/* 704 70520151030: 706 The OpenSSL has been upgraded to 1.0.2d. Any binaries requiring 707 libcrypto.so.7 or libssl.so.7 must be recompiled. 708 70920151020: 710 Qlogic 24xx/25xx firmware images were updated from 5.5.0 to 7.3.0. 711 Kernel modules isp_2400_multi and isp_2500_multi were removed and 712 should be replaced with isp_2400 and isp_2500 modules respectively. 713 71420151017: 715 The build previously allowed using 'make -n' to not recurse into 716 sub-directories while showing what commands would be executed, and 717 'make -n -n' to recursively show commands. Now 'make -n' will recurse 718 and 'make -N' will not. 719 72020151012: 721 If you specify SENDMAIL_MC or SENDMAIL_CF in make.conf, mergemaster 722 and etcupdate will now use this file. A custom sendmail.cf is now 723 updated via this mechanism rather than via installworld. If you had 724 excluded sendmail.cf in mergemaster.rc or etcupdate.conf, you may 725 want to remove the exclusion or change it to "always install". 726 /etc/mail/sendmail.cf is now managed the same way regardless of 727 whether SENDMAIL_MC/SENDMAIL_CF is used. If you are not using 728 SENDMAIL_MC/SENDMAIL_CF there should be no change in behavior. 729 73020151011: 731 Compatibility shims for legacy ATA device names have been removed. 732 It includes ATA_STATIC_ID kernel option, kern.cam.ada.legacy_aliases 733 and kern.geom.raid.legacy_aliases loader tunables, kern.devalias.* 734 environment variables, /dev/ad* and /dev/ar* symbolic links. 735 73620151006: 737 Clang, llvm, lldb, compiler-rt and libc++ have been upgraded to 3.7.0. 738 Please see the 20141231 entry below for information about prerequisites 739 and upgrading, if you are not already using clang 3.5.0 or higher. 740 74120150924: 742 Kernel debug files have been moved to /usr/lib/debug/boot/kernel/, 743 and renamed from .symbols to .debug. This reduces the size requirements 744 on the boot partition or file system and provides consistency with 745 userland debug files. 746 747 When using the supported kernel installation method the 748 /usr/lib/debug/boot/kernel directory will be renamed (to kernel.old) 749 as is done with /boot/kernel. 750 751 Developers wishing to maintain the historical behavior of installing 752 debug files in /boot/kernel/ can set KERN_DEBUGDIR="" in src.conf(5). 753 75420150827: 755 The wireless drivers had undergone changes that remove the 'parent 756 interface' from the ifconfig -l output. The rc.d network scripts 757 used to check presence of a parent interface in the list, so old 758 scripts would fail to start wireless networking. Thus, etcupdate(3) 759 or mergemaster(8) run is required after kernel update, to update your 760 rc.d scripts in /etc. 761 76220150827: 763 pf no longer supports 'scrub fragment crop' or 'scrub fragment drop-ovl' 764 These configurations are now automatically interpreted as 765 'scrub fragment reassemble'. 766 76720150817: 768 Kernel-loadable modules for the random(4) device are back. To use 769 them, the kernel must have 770 771 device random 772 options RANDOM_LOADABLE 773 774 kldload(8) can then be used to load random_fortuna.ko 775 or random_yarrow.ko. Please note that due to the indirect 776 function calls that the loadable modules need to provide, 777 the build-in variants will be slightly more efficient. 778 779 The random(4) kernel option RANDOM_DUMMY has been retired due to 780 unpopularity. It was not all that useful anyway. 781 78220150813: 783 The WITHOUT_ELFTOOLCHAIN_TOOLS src.conf(5) knob has been retired. 784 Control over building the ELF Tool Chain tools is now provided by 785 the WITHOUT_TOOLCHAIN knob. 786 78720150810: 788 The polarity of Pulse Per Second (PPS) capture events with the 789 uart(4) driver has been corrected. Prior to this change the PPS 790 "assert" event corresponded to the trailing edge of a positive PPS 791 pulse and the "clear" event was the leading edge of the next pulse. 792 793 As the width of a PPS pulse in a typical GPS receiver is on the 794 order of 1 millisecond, most users will not notice any significant 795 difference with this change. 796 797 Anyone who has compensated for the historical polarity reversal by 798 configuring a negative offset equal to the pulse width will need to 799 remove that workaround. 800 80120150809: 802 The default group assigned to /dev/dri entries has been changed 803 from 'wheel' to 'video' with the id of '44'. If you want to have 804 access to the dri devices please add yourself to the video group 805 with: 806 807 # pw groupmod video -m $USER 808 80920150806: 810 The menu.rc and loader.rc files will now be replaced during 811 upgrades. Please migrate local changes to menu.rc.local and 812 loader.rc.local instead. 813 81420150805: 815 GNU Binutils versions of addr2line, c++filt, nm, readelf, size, 816 strings and strip have been removed. The src.conf(5) knob 817 WITHOUT_ELFTOOLCHAIN_TOOLS no longer provides the binutils tools. 818 81920150728: 820 As ZFS requires more kernel stack pages than is the default on some 821 architectures e.g. i386, it now warns if KSTACK_PAGES is less than 822 ZFS_MIN_KSTACK_PAGES (which is 4 at the time of writing). 823 824 Please consider using 'options KSTACK_PAGES=X' where X is greater 825 than or equal to ZFS_MIN_KSTACK_PAGES i.e. 4 in such configurations. 826 82720150706: 828 sendmail has been updated to 8.15.2. Starting with FreeBSD 11.0 829 and sendmail 8.15, sendmail uses uncompressed IPv6 addresses by 830 default, i.e., they will not contain "::". For example, instead 831 of ::1, it will be 0:0:0:0:0:0:0:1. This permits a zero subnet 832 to have a more specific match, such as different map entries for 833 IPv6:0:0 vs IPv6:0. This change requires that configuration 834 data (including maps, files, classes, custom ruleset, etc.) must 835 use the same format, so make certain such configuration data is 836 upgrading. As a very simple check search for patterns like 837 'IPv6:[0-9a-fA-F:]*::' and 'IPv6::'. To return to the old 838 behavior, set the m4 option confUSE_COMPRESSED_IPV6_ADDRESSES or 839 the cf option UseCompressedIPv6Addresses. 840 84120150630: 842 The default kernel entropy-processing algorithm is now 843 Fortuna, replacing Yarrow. 844 845 Assuming you have 'device random' in your kernel config 846 file, the configurations allow a kernel option to override 847 this default. You may choose *ONE* of: 848 849 options RANDOM_YARROW # Legacy /dev/random algorithm. 850 options RANDOM_DUMMY # Blocking-only driver. 851 852 If you have neither, you get Fortuna. For most people, 853 read no further, Fortuna will give a /dev/random that works 854 like it always used to, and the difference will be irrelevant. 855 856 If you remove 'device random', you get *NO* kernel-processed 857 entropy at all. This may be acceptable to folks building 858 embedded systems, but has complications. Carry on reading, 859 and it is assumed you know what you need. 860 861 *PLEASE* read random(4) and random(9) if you are in the 862 habit of tweaking kernel configs, and/or if you are a member 863 of the embedded community, wanting specific and not-usual 864 behaviour from your security subsystems. 865 866 NOTE!! If you use RANDOM_DUMMY and/or have no 'device 867 random', you will NOT have a functioning /dev/random, and 868 many cryptographic features will not work, including SSH. 869 You may also find strange behaviour from the random(3) set 870 of library functions, in particular sranddev(3), srandomdev(3) 871 and arc4random(3). The reason for this is that the KERN_ARND 872 sysctl only returns entropy if it thinks it has some to 873 share, and with RANDOM_DUMMY or no 'device random' this 874 will never happen. 875 87620150623: 877 An additional fix for the issue described in the 20150614 sendmail 878 entry below has been committed in revision 284717. 879 88020150616: 881 FreeBSD's old make (fmake) has been removed from the system. It is 882 available as the devel/fmake port or via pkg install fmake. 883 88420150615: 885 The fix for the issue described in the 20150614 sendmail entry 886 below has been committed in revision 284436. The work 887 around described in that entry is no longer needed unless the 888 default setting is overridden by a confDH_PARAMETERS configuration 889 setting of '5' or pointing to a 512 bit DH parameter file. 890 89120150614: 892 ALLOW_DEPRECATED_ATF_TOOLS/ATFFILE support has been removed from 893 atf.test.mk (included from bsd.test.mk). Please upgrade devel/atf 894 and devel/kyua to version 0.20+ and adjust any calling code to work 895 with Kyuafile and kyua. 896 89720150614: 898 The import of openssl to address the FreeBSD-SA-15:10.openssl 899 security advisory includes a change which rejects handshakes 900 with DH parameters below 768 bits. sendmail releases prior 901 to 8.15.2 (not yet released), defaulted to a 512 bit 902 DH parameter setting for client connections. To work around 903 this interoperability, sendmail can be configured to use a 904 2048 bit DH parameter by: 905 906 1. Edit /etc/mail/`hostname`.mc 907 2. If a setting for confDH_PARAMETERS does not exist or 908 exists and is set to a string beginning with '5', 909 replace it with '2'. 910 3. If a setting for confDH_PARAMETERS exists and is set to 911 a file path, create a new file with: 912 openssl dhparam -out /path/to/file 2048 913 4. Rebuild the .cf file: 914 cd /etc/mail/; make; make install 915 5. Restart sendmail: 916 cd /etc/mail/; make restart 917 918 A sendmail patch is coming, at which time this file will be 919 updated. 920 92120150604: 922 Generation of legacy formatted entries have been disabled by default 923 in pwd_mkdb(8), as all base system consumers of the legacy formatted 924 entries were converted to use the new format by default when the new, 925 machine independent format have been added and supported since FreeBSD 926 5.x. 927 928 Please see the pwd_mkdb(8) manual page for further details. 929 93020150525: 931 Clang and llvm have been upgraded to 3.6.1 release. Please see the 932 20141231 entry below for information about prerequisites and upgrading, 933 if you are not already using 3.5.0 or higher. 934 93520150521: 936 TI platform code switched to using vendor DTS files and this update 937 may break existing systems running on Beaglebone, Beaglebone Black, 938 and Pandaboard: 939 940 - dtb files should be regenerated/reinstalled. Filenames are the 941 same but content is different now 942 - GPIO addressing was changed, now each GPIO bank (32 pins per bank) 943 has its own /dev/gpiocX device, e.g. pin 121 on /dev/gpioc0 in old 944 addressing scheme is now pin 25 on /dev/gpioc3. 945 - Pandaboard: /etc/ttys should be updated, serial console device is 946 now /dev/ttyu2, not /dev/ttyu0 947 94820150501: 949 soelim(1) from gnu/usr.bin/groff has been replaced by usr.bin/soelim. 950 If you need the GNU extension from groff soelim(1), install groff 951 from package: pkg install groff, or via ports: textproc/groff. 952 95320150423: 954 chmod, chflags, chown and chgrp now affect symlinks in -R mode as 955 defined in symlink(7); previously symlinks were silently ignored. 956 95720150415: 958 The const qualifier has been removed from iconv(3) to comply with 959 POSIX. The ports tree is aware of this from r384038 onwards. 960 96120150416: 962 Libraries specified by LIBADD in Makefiles must have a corresponding 963 DPADD_<lib> variable to ensure correct dependencies. This is now 964 enforced in src.libnames.mk. 965 96620150324: 967 From legacy ata(4) driver was removed support for SATA controllers 968 supported by more functional drivers ahci(4), siis(4) and mvs(4). 969 Kernel modules ataahci and ataadaptec were removed completely, 970 replaced by ahci and mvs modules respectively. 971 97220150315: 973 Clang, llvm and lldb have been upgraded to 3.6.0 release. Please see 974 the 20141231 entry below for information about prerequisites and 975 upgrading, if you are not already using 3.5.0 or higher. 976 97720150307: 978 The 32-bit PowerPC kernel has been changed to a position-independent 979 executable. This can only be booted with a version of loader(8) 980 newer than January 31, 2015, so make sure to update both world and 981 kernel before rebooting. 982 98320150217: 984 If you are running a -CURRENT kernel since r273872 (Oct 30th, 2014), 985 but before r278950, the RNG was not seeded properly. Immediately 986 upgrade the kernel to r278950 or later and regenerate any keys (e.g. 987 ssh keys or openssl keys) that were generated w/ a kernel from that 988 range. This does not affect programs that directly used /dev/random 989 or /dev/urandom. All userland uses of arc4random(3) are affected. 990 99120150210: 992 The autofs(4) ABI was changed in order to restore binary compatibility 993 with 10.1-RELEASE. The automountd(8) daemon needs to be rebuilt to work 994 with the new kernel. 995 99620150131: 997 The powerpc64 kernel has been changed to a position-independent 998 executable. This can only be booted with a new version of loader(8), 999 so make sure to update both world and kernel before rebooting. 1000 100120150118: 1002 Clang and llvm have been upgraded to 3.5.1 release. This is a bugfix 1003 only release, no new features have been added. Please see the 20141231 1004 entry below for information about prerequisites and upgrading, if you 1005 are not already using 3.5.0. 1006 100720150107: 1008 ELF tools addr2line, elfcopy (strip), nm, size, and strings are now 1009 taken from the ELF Tool Chain project rather than GNU binutils. They 1010 should be drop-in replacements, with the addition of arm64 support. 1011 The WITHOUT_ELFTOOLCHAIN_TOOLS= knob may be used to obtain the 1012 binutils tools, if necessary. See 20150805 for updated information. 1013 101420150105: 1015 The default Unbound configuration now enables remote control 1016 using a local socket. Users who have already enabled the 1017 local_unbound service should regenerate their configuration 1018 by running "service local_unbound setup" as root. 1019 102020150102: 1021 The GNU texinfo and GNU info pages have been removed. 1022 To be able to view GNU info pages please install texinfo from ports. 1023 102420141231: 1025 Clang, llvm and lldb have been upgraded to 3.5.0 release. 1026 1027 As of this release, a prerequisite for building clang, llvm and lldb is 1028 a C++11 capable compiler and C++11 standard library. This means that to 1029 be able to successfully build the cross-tools stage of buildworld, with 1030 clang as the bootstrap compiler, your system compiler or cross compiler 1031 should either be clang 3.3 or later, or gcc 4.8 or later, and your 1032 system C++ library should be libc++, or libdstdc++ from gcc 4.8 or 1033 later. 1034 1035 On any standard FreeBSD 10.x or 11.x installation, where clang and 1036 libc++ are on by default (that is, on x86 or arm), this should work out 1037 of the box. 1038 1039 On 9.x installations where clang is enabled by default, e.g. on x86 and 1040 powerpc, libc++ will not be enabled by default, so libc++ should be 1041 built (with clang) and installed first. If both clang and libc++ are 1042 missing, build clang first, then use it to build libc++. 1043 1044 On 8.x and earlier installations, upgrade to 9.x first, and then follow 1045 the instructions for 9.x above. 1046 1047 Sparc64 and mips users are unaffected, as they still use gcc 4.2.1 by 1048 default, and do not build clang. 1049 1050 Many embedded systems are resource constrained, and will not be able to 1051 build clang in a reasonable time, or in some cases at all. In those 1052 cases, cross building bootable systems on amd64 is a workaround. 1053 1054 This new version of clang introduces a number of new warnings, of which 1055 the following are most likely to appear: 1056 1057 -Wabsolute-value 1058 1059 This warns in two cases, for both C and C++: 1060 * When the code is trying to take the absolute value of an unsigned 1061 quantity, which is effectively a no-op, and almost never what was 1062 intended. The code should be fixed, if at all possible. If you are 1063 sure that the unsigned quantity can be safely cast to signed, without 1064 loss of information or undefined behavior, you can add an explicit 1065 cast, or disable the warning. 1066 1067 * When the code is trying to take an absolute value, but the called 1068 abs() variant is for the wrong type, which can lead to truncation. 1069 If you want to disable the warning instead of fixing the code, please 1070 make sure that truncation will not occur, or it might lead to unwanted 1071 side-effects. 1072 1073 -Wtautological-undefined-compare and 1074 -Wundefined-bool-conversion 1075 1076 These warn when C++ code is trying to compare 'this' against NULL, while 1077 'this' should never be NULL in well-defined C++ code. However, there is 1078 some legacy (pre C++11) code out there, which actively abuses this 1079 feature, which was less strictly defined in previous C++ versions. 1080 1081 Squid and openjdk do this, for example. The warning can be turned off 1082 for C++98 and earlier, but compiling the code in C++11 mode might result 1083 in unexpected behavior; for example, the parts of the program that are 1084 unreachable could be optimized away. 1085 108620141222: 1087 The old NFS client and server (kernel options NFSCLIENT, NFSSERVER) 1088 kernel sources have been removed. The .h files remain, since some 1089 utilities include them. This will need to be fixed later. 1090 If "mount -t oldnfs ..." is attempted, it will fail. 1091 If the "-o" option on mountd(8), nfsd(8) or nfsstat(1) is used, 1092 the utilities will report errors. 1093 109420141121: 1095 The handling of LOCAL_LIB_DIRS has been altered to skip addition of 1096 directories to top level SUBDIR variable when their parent 1097 directory is included in LOCAL_DIRS. Users with build systems with 1098 such hierarchies and without SUBDIR entries in the parent 1099 directory Makefiles should add them or add the directories to 1100 LOCAL_DIRS. 1101 110220141109: 1103 faith(4) and faithd(8) have been removed from the base system. Faith 1104 has been obsolete for a very long time. 1105 110620141104: 1107 vt(4), the new console driver, is enabled by default. It brings 1108 support for Unicode and double-width characters, as well as 1109 support for UEFI and integration with the KMS kernel video 1110 drivers. 1111 1112 You may need to update your console settings in /etc/rc.conf, 1113 most probably the keymap. During boot, /etc/rc.d/syscons will 1114 indicate what you need to do. 1115 1116 vt(4) still has issues and lacks some features compared to 1117 syscons(4). See the wiki for up-to-date information: 1118 https://wiki.freebsd.org/Newcons 1119 1120 If you want to keep using syscons(4), you can do so by adding 1121 the following line to /boot/loader.conf: 1122 kern.vty=sc 1123 112420141102: 1125 pjdfstest has been integrated into kyua as an opt-in test suite. 1126 Please see share/doc/pjdfstest/README for more details on how to 1127 execute it. 1128 112920141009: 1130 gperf has been removed from the base system for architectures 1131 that use clang. Ports that require gperf will obtain it from the 1132 devel/gperf port. 1133 113420140923: 1135 pjdfstest has been moved from tools/regression/pjdfstest to 1136 contrib/pjdfstest . 1137 113820140922: 1139 At svn r271982, The default linux compat kernel ABI has been adjusted 1140 to 2.6.18 in support of the linux-c6 compat ports infrastructure 1141 update. If you wish to continue using the linux-f10 compat ports, 1142 add compat.linux.osrelease=2.6.16 to your local sysctl.conf. Users are 1143 encouraged to update their linux-compat packages to linux-c6 during 1144 their next update cycle. 1145 114620140729: 1147 The ofwfb driver, used to provide a graphics console on PowerPC when 1148 using vt(4), no longer allows mmap() of all physical memory. This 1149 will prevent Xorg on PowerPC with some ATI graphics cards from 1150 initializing properly unless x11-servers/xorg-server is updated to 1151 1.12.4_8 or newer. 1152 115320140723: 1154 The xdev targets have been converted to using TARGET and 1155 TARGET_ARCH instead of XDEV and XDEV_ARCH. 1156 115720140719: 1158 The default unbound configuration has been modified to address 1159 issues with reverse lookups on networks that use private 1160 address ranges. If you use the local_unbound service, run 1161 "service local_unbound setup" as root to regenerate your 1162 configuration, then "service local_unbound reload" to load the 1163 new configuration. 1164 116520140709: 1166 The GNU texinfo and GNU info pages are not built and installed 1167 anymore, WITH_INFO knob has been added to allow to built and install 1168 them again. 1169 UPDATE: see 20150102 entry on texinfo's removal 1170 117120140708: 1172 The GNU readline library is now an INTERNALLIB - that is, it is 1173 statically linked into consumers (GDB and variants) in the base 1174 system, and the shared library is no longer installed. The 1175 devel/readline port is available for third party software that 1176 requires readline. 1177 117820140702: 1179 The Itanium architecture (ia64) has been removed from the list of 1180 known architectures. This is the first step in the removal of the 1181 architecture. 1182 118320140701: 1184 Commit r268115 has added NFSv4.1 server support, merged from 1185 projects/nfsv4.1-server. Since this includes changes to the 1186 internal interfaces between the NFS related modules, a full 1187 build of the kernel and modules will be necessary. 1188 __FreeBSD_version has been bumped. 1189 119020140629: 1191 The WITHOUT_VT_SUPPORT kernel config knob has been renamed 1192 WITHOUT_VT. (The other _SUPPORT knobs have a consistent meaning 1193 which differs from the behaviour controlled by this knob.) 1194 119520140619: 1196 Maximal length of the serial number in CTL was increased from 16 to 1197 64 chars, that breaks ABI. All CTL-related tools, such as ctladm 1198 and ctld, need to be rebuilt to work with a new kernel. 1199 120020140606: 1201 The libatf-c and libatf-c++ major versions were downgraded to 0 and 1202 1 respectively to match the upstream numbers. They were out of 1203 sync because, when they were originally added to FreeBSD, the 1204 upstream versions were not respected. These libraries are private 1205 and not yet built by default, so renumbering them should be a 1206 non-issue. However, unclean source trees will yield broken test 1207 programs once the operator executes "make delete-old-libs" after a 1208 "make installworld". 1209 1210 Additionally, the atf-sh binary was made private by moving it into 1211 /usr/libexec/. Already-built shell test programs will keep the 1212 path to the old binary so they will break after "make delete-old" 1213 is run. 1214 1215 If you are using WITH_TESTS=yes (not the default), wipe the object 1216 tree and rebuild from scratch to prevent spurious test failures. 1217 This is only needed once: the misnumbered libraries and misplaced 1218 binaries have been added to OptionalObsoleteFiles.inc so they will 1219 be removed during a clean upgrade. 1220 122120140512: 1222 Clang and llvm have been upgraded to 3.4.1 release. 1223 122420140508: 1225 We bogusly installed src.opts.mk in /usr/share/mk. This file should 1226 be removed to avoid issues in the future (and has been added to 1227 ObsoleteFiles.inc). 1228 122920140505: 1230 /etc/src.conf now affects only builds of the FreeBSD src tree. In the 1231 past, it affected all builds that used the bsd.*.mk files. The old 1232 behavior was a bug, but people may have relied upon it. To get this 1233 behavior back, you can .include /etc/src.conf from /etc/make.conf 1234 (which is still global and isn't changed). This also changes the 1235 behavior of incremental builds inside the tree of individual 1236 directories. Set MAKESYSPATH to ".../share/mk" to do that. 1237 Although this has survived make universe and some upgrade scenarios, 1238 other upgrade scenarios may have broken. At least one form of 1239 temporary breakage was fixed with MAKESYSPATH settings for buildworld 1240 as well... In cases where MAKESYSPATH isn't working with this 1241 setting, you'll need to set it to the full path to your tree. 1242 1243 One side effect of all this cleaning up is that bsd.compiler.mk 1244 is no longer implicitly included by bsd.own.mk. If you wish to 1245 use COMPILER_TYPE, you must now explicitly include bsd.compiler.mk 1246 as well. 1247 124820140430: 1249 The lindev device has been removed since /dev/full has been made a 1250 standard device. __FreeBSD_version has been bumped. 1251 125220140424: 1253 The knob WITHOUT_VI was added to the base system, which controls 1254 building ex(1), vi(1), etc. Older releases of FreeBSD required ex(1) 1255 in order to reorder files share/termcap and didn't build ex(1) as a 1256 build tool, so building/installing with WITH_VI is highly advised for 1257 build hosts for older releases. 1258 1259 This issue has been fixed in stable/9 and stable/10 in r277022 and 1260 r276991, respectively. 1261 126220140418: 1263 The YES_HESIOD knob has been removed. It has been obsolete for 1264 a decade. Please move to using WITH_HESIOD instead or your builds 1265 will silently lack HESIOD. 1266 126720140405: 1268 The uart(4) driver has been changed with respect to its handling 1269 of the low-level console. Previously the uart(4) driver prevented 1270 any process from changing the baudrate or the CLOCAL and HUPCL 1271 control flags. By removing the restrictions, operators can make 1272 changes to the serial console port without having to reboot. 1273 However, when getty(8) is started on the serial device that is 1274 associated with the low-level console, a misconfigured terminal 1275 line in /etc/ttys will now have a real impact. 1276 Before upgrading the kernel, make sure that /etc/ttys has the 1277 serial console device configured as 3wire without baudrate to 1278 preserve the previous behaviour. E.g: 1279 ttyu0 "/usr/libexec/getty 3wire" vt100 on secure 1280 128120140306: 1282 Support for libwrap (TCP wrappers) in rpcbind was disabled by default 1283 to improve performance. To re-enable it, if needed, run rpcbind 1284 with command line option -W. 1285 128620140226: 1287 Switched back to the GPL dtc compiler due to updates in the upstream 1288 dts files not being supported by the BSDL dtc compiler. You will need 1289 to rebuild your kernel toolchain to pick up the new compiler. Core dumps 1290 may result while building dtb files during a kernel build if you fail 1291 to do so. Set WITHOUT_GPL_DTC if you require the BSDL compiler. 1292 129320140216: 1294 Clang and llvm have been upgraded to 3.4 release. 1295 129620140216: 1297 The nve(4) driver has been removed. Please use the nfe(4) driver 1298 for NVIDIA nForce MCP Ethernet adapters instead. 1299 130020140212: 1301 An ABI incompatibility crept into the libc++ 3.4 import in r261283. 1302 This could cause certain C++ applications using shared libraries built 1303 against the previous version of libc++ to crash. The incompatibility 1304 has now been fixed, but any C++ applications or shared libraries built 1305 between r261283 and r261801 should be recompiled. 1306 130720140204: 1308 OpenSSH will now ignore errors caused by kernel lacking of Capsicum 1309 capability mode support. Please note that enabling the feature in 1310 kernel is still highly recommended. 1311 131220140131: 1313 OpenSSH is now built with sandbox support, and will use sandbox as 1314 the default privilege separation method. This requires Capsicum 1315 capability mode support in kernel. 1316 131720140128: 1318 The libelf and libdwarf libraries have been updated to newer 1319 versions from upstream. Shared library version numbers for 1320 these two libraries were bumped. Any ports or binaries 1321 requiring these two libraries should be recompiled. 1322 __FreeBSD_version is bumped to 1100006. 1323 132420140110: 1325 If a Makefile in a tests/ directory was auto-generating a Kyuafile 1326 instead of providing an explicit one, this would prevent such 1327 Makefile from providing its own Kyuafile in the future during 1328 NO_CLEAN builds. This has been fixed in the Makefiles but manual 1329 intervention is needed to clean an objdir if you use NO_CLEAN: 1330 # find /usr/obj -name Kyuafile | xargs rm -f 1331 133220131213: 1333 The behavior of gss_pseudo_random() for the krb5 mechanism 1334 has changed, for applications requesting a longer random string 1335 than produced by the underlying enctype's pseudo-random() function. 1336 In particular, the random string produced from a session key of 1337 enctype aes256-cts-hmac-sha1-96 or aes256-cts-hmac-sha1-96 will 1338 be different at the 17th octet and later, after this change. 1339 The counter used in the PRF+ construction is now encoded as a 1340 big-endian integer in accordance with RFC 4402. 1341 __FreeBSD_version is bumped to 1100004. 1342 134320131108: 1344 The WITHOUT_ATF build knob has been removed and its functionality 1345 has been subsumed into the more generic WITHOUT_TESTS. If you were 1346 using the former to disable the build of the ATF libraries, you 1347 should change your settings to use the latter. 1348 134920131025: 1350 The default version of mtree is nmtree which is obtained from 1351 NetBSD. The output is generally the same, but may vary 1352 slightly. If you found you need identical output adding 1353 "-F freebsd9" to the command line should do the trick. For the 1354 time being, the old mtree is available as fmtree. 1355 135620131014: 1357 libbsdyml has been renamed to libyaml and moved to /usr/lib/private. 1358 This will break ports-mgmt/pkg. Rebuild the port, or upgrade to pkg 1359 1.1.4_8 and verify bsdyml not linked in, before running "make 1360 delete-old-libs": 1361 # make -C /usr/ports/ports-mgmt/pkg build deinstall install clean 1362 or 1363 # pkg install pkg; ldd /usr/local/sbin/pkg | grep bsdyml 1364 136520131010: 1366 The stable/10 branch has been created in subversion from head 1367 revision r256279. 1368 136920131010: 1370 The rc.d/jail script has been updated to support jail(8) 1371 configuration file. The "jail_<jname>_*" rc.conf(5) variables 1372 for per-jail configuration are automatically converted to 1373 /var/run/jail.<jname>.conf before the jail(8) utility is invoked. 1374 This is transparently backward compatible. See below about some 1375 incompatibilities and rc.conf(5) manual page for more details. 1376 1377 These variables are now deprecated in favor of jail(8) configuration 1378 file. One can use "rc.d/jail config <jname>" command to generate 1379 a jail(8) configuration file in /var/run/jail.<jname>.conf without 1380 running the jail(8) utility. The default pathname of the 1381 configuration file is /etc/jail.conf and can be specified by 1382 using $jail_conf or $jail_<jname>_conf variables. 1383 1384 Please note that jail_devfs_ruleset accepts an integer at 1385 this moment. Please consider to rewrite the ruleset name 1386 with an integer. 1387 138820130930: 1389 BIND has been removed from the base system. If all you need 1390 is a local resolver, simply enable and start the local_unbound 1391 service instead. Otherwise, several versions of BIND are 1392 available in the ports tree. The dns/bind99 port is one example. 1393 1394 With this change, nslookup(1) and dig(1) are no longer in the base 1395 system. Users should instead use host(1) and drill(1) which are 1396 in the base system. Alternatively, nslookup and dig can 1397 be obtained by installing the dns/bind-tools port. 1398 139920130916: 1400 With the addition of unbound(8), a new unbound user is now 1401 required during installworld. "mergemaster -p" can be used to 1402 add the user prior to installworld, as documented in the handbook. 1403 140420130911: 1405 OpenSSH is now built with DNSSEC support, and will by default 1406 silently trust signed SSHFP records. This can be controlled with 1407 the VerifyHostKeyDNS client configuration setting. DNSSEC support 1408 can be disabled entirely with the WITHOUT_LDNS option in src.conf. 1409 141020130906: 1411 The GNU Compiler Collection and C++ standard library (libstdc++) 1412 are no longer built by default on platforms where clang is the system 1413 compiler. You can enable them with the WITH_GCC and WITH_GNUCXX 1414 options in src.conf. 1415 141620130905: 1417 The PROCDESC kernel option is now part of the GENERIC kernel 1418 configuration and is required for the rwhod(8) to work. 1419 If you are using custom kernel configuration, you should include 1420 'options PROCDESC'. 1421 142220130905: 1423 The API and ABI related to the Capsicum framework was modified 1424 in backward incompatible way. The userland libraries and programs 1425 have to be recompiled to work with the new kernel. This includes the 1426 following libraries and programs, but the whole buildworld is 1427 advised: libc, libprocstat, dhclient, tcpdump, hastd, hastctl, 1428 kdump, procstat, rwho, rwhod, uniq. 1429 143020130903: 1431 AES-NI intrinsic support has been added to gcc. The AES-NI module 1432 has been updated to use this support. A new gcc is required to build 1433 the aesni module on both i386 and amd64. 1434 143520130821: 1436 The PADLOCK_RNG and RDRAND_RNG kernel options are now devices. 1437 Thus "device padlock_rng" and "device rdrand_rng" should be 1438 used instead of "options PADLOCK_RNG" & "options RDRAND_RNG". 1439 144020130813: 1441 WITH_ICONV has been split into two feature sets. WITH_ICONV now 1442 enables just the iconv* functionality and is now on by default. 1443 WITH_LIBICONV_COMPAT enables the libiconv api and link time 1444 compatibility. Set WITHOUT_ICONV to build the old way. 1445 If you have been using WITH_ICONV before, you will very likely 1446 need to turn on WITH_LIBICONV_COMPAT. 1447 144820130806: 1449 INVARIANTS option now enables DEBUG for code with OpenSolaris and 1450 Illumos origin, including ZFS. If you have INVARIANTS in your 1451 kernel configuration, then there is no need to set DEBUG or ZFS_DEBUG 1452 explicitly. 1453 DEBUG used to enable witness(9) tracking of OpenSolaris (mostly ZFS) 1454 locks if WITNESS option was set. Because that generated a lot of 1455 witness(9) reports and all of them were believed to be false 1456 positives, this is no longer done. New option OPENSOLARIS_WITNESS 1457 can be used to achieve the previous behavior. 1458 145920130806: 1460 Timer values in IPv6 data structures now use time_uptime instead 1461 of time_second. Although this is not a user-visible functional 1462 change, userland utilities which directly use them---ndp(8), 1463 rtadvd(8), and rtsold(8) in the base system---need to be updated 1464 to r253970 or later. 1465 146620130802: 1467 find -delete can now delete the pathnames given as arguments, 1468 instead of only files found below them or if the pathname did 1469 not contain any slashes. Formerly, the following error message 1470 would result: 1471 1472 find: -delete: <path>: relative path potentially not safe 1473 1474 Deleting the pathnames given as arguments can be prevented 1475 without error messages using -mindepth 1 or by changing 1476 directory and passing "." as argument to find. This works in the 1477 old as well as the new version of find. 1478 147920130726: 1480 Behavior of devfs rules path matching has been changed. 1481 Pattern is now always matched against fully qualified devfs 1482 path and slash characters must be explicitly matched by 1483 slashes in pattern (FNM_PATHNAME). Rulesets involving devfs 1484 subdirectories must be reviewed. 1485 148620130716: 1487 The default ARM ABI has changed to the ARM EABI. The old ABI is 1488 incompatible with the ARM EABI and all programs and modules will 1489 need to be rebuilt to work with a new kernel. 1490 1491 To keep using the old ABI ensure the WITHOUT_ARM_EABI knob is set. 1492 1493 NOTE: Support for the old ABI will be removed in the future and 1494 users are advised to upgrade. 1495 149620130709: 1497 pkg_install has been disconnected from the build if you really need it 1498 you should add WITH_PKGTOOLS in your src.conf(5). 1499 150020130709: 1501 Most of network statistics structures were changed to be able 1502 keep 64-bits counters. Thus all tools, that work with networking 1503 statistics, must be rebuilt (netstat(1), bsnmpd(1), etc.) 1504 150520130618: 1506 Fix a bug that allowed a tracing process (e.g. gdb) to write 1507 to a memory-mapped file in the traced process's address space 1508 even if neither the traced process nor the tracing process had 1509 write access to that file. 1510 151120130615: 1512 CVS has been removed from the base system. An exact copy 1513 of the code is available from the devel/cvs port. 1514 151520130613: 1516 Some people report the following error after the switch to bmake: 1517 1518 make: illegal option -- J 1519 usage: make [-BPSXeiknpqrstv] [-C directory] [-D variable] 1520 ... 1521 *** [buildworld] Error code 2 1522 1523 this likely due to an old instance of make in 1524 ${MAKEPATH} (${MAKEOBJDIRPREFIX}${.CURDIR}/make.${MACHINE}) 1525 which src/Makefile will use that blindly, if it exists, so if 1526 you see the above error: 1527 1528 rm -rf `make -V MAKEPATH` 1529 1530 should resolve it. 1531 153220130516: 1533 Use bmake by default. 1534 Whereas before one could choose to build with bmake via 1535 -DWITH_BMAKE one must now use -DWITHOUT_BMAKE to use the old 1536 make. The goal is to remove these knobs for 10-RELEASE. 1537 1538 It is worth noting that bmake (like gmake) treats the command 1539 line as the unit of failure, rather than statements within the 1540 command line. Thus '(cd some/where && dosomething)' is safer 1541 than 'cd some/where; dosomething'. The '()' allows consistent 1542 behavior in parallel build. 1543 154420130429: 1545 Fix a bug that allows NFS clients to issue READDIR on files. 1546 154720130426: 1548 The WITHOUT_IDEA option has been removed because 1549 the IDEA patent expired. 1550 155120130426: 1552 The sysctl which controls TRIM support under ZFS has been renamed 1553 from vfs.zfs.trim_disable -> vfs.zfs.trim.enabled and has been 1554 enabled by default. 1555 155620130425: 1557 The mergemaster command now uses the default MAKEOBJDIRPREFIX 1558 rather than creating it's own in the temporary directory in 1559 order allow access to bootstrapped versions of tools such as 1560 install and mtree. When upgrading from version of FreeBSD where 1561 the install command does not support -l, you will need to 1562 install a new mergemaster command if mergemaster -p is required. 1563 This can be accomplished with the command (cd src/usr.sbin/mergemaster 1564 && make install). 1565 156620130404: 1567 Legacy ATA stack, disabled and replaced by new CAM-based one since 1568 FreeBSD 9.0, completely removed from the sources. Kernel modules 1569 atadisk and atapi*, user-level tools atacontrol and burncd are 1570 removed. Kernel option `options ATA_CAM` is now permanently enabled 1571 and removed. 1572 157320130319: 1574 SOCK_CLOEXEC and SOCK_NONBLOCK flags have been added to socket(2) 1575 and socketpair(2). Software, in particular Kerberos, may 1576 automatically detect and use these during building. The resulting 1577 binaries will not work on older kernels. 1578 157920130308: 1580 CTL_DISABLE has also been added to the sparc64 GENERIC (for further 1581 information, see the respective 20130304 entry). 1582 158320130304: 1584 Recent commits to callout(9) changed the size of struct callout, 1585 so the KBI is probably heavily disturbed. Also, some functions 1586 in callout(9)/sleep(9)/sleepqueue(9)/condvar(9) KPIs were replaced 1587 by macros. Every kernel module using it won't load, so rebuild 1588 is requested. 1589 1590 The ctl device has been re-enabled in GENERIC for i386 and amd64, 1591 but does not initialize by default (because of the new CTL_DISABLE 1592 option) to save memory. To re-enable it, remove the CTL_DISABLE 1593 option from the kernel config file or set kern.cam.ctl.disable=0 1594 in /boot/loader.conf. 1595 159620130301: 1597 The ctl device has been disabled in GENERIC for i386 and amd64. 1598 This was done due to the extra memory being allocated at system 1599 initialisation time by the ctl driver which was only used if 1600 a CAM target device was created. This makes a FreeBSD system 1601 unusable on 128MB or less of RAM. 1602 160320130208: 1604 A new compression method (lz4) has been merged to -HEAD. Please 1605 refer to zpool-features(7) for more information. 1606 1607 Please refer to the "ZFS notes" section of this file for information 1608 on upgrading boot ZFS pools. 1609 161020130129: 1611 A BSD-licensed patch(1) variant has been added and is installed 1612 as bsdpatch, being the GNU version the default patch. 1613 To inverse the logic and use the BSD-licensed one as default, 1614 while having the GNU version installed as gnupatch, rebuild 1615 and install world with the WITH_BSD_PATCH knob set. 1616 161720130121: 1618 Due to the use of the new -l option to install(1) during build 1619 and install, you must take care not to directly set the INSTALL 1620 make variable in your /etc/make.conf, /etc/src.conf, or on the 1621 command line. If you wish to use the -C flag for all installs 1622 you may be able to add INSTALL+=-C to /etc/make.conf or 1623 /etc/src.conf. 1624 162520130118: 1626 The install(1) option -M has changed meaning and now takes an 1627 argument that is a file or path to append logs to. In the 1628 unlikely event that -M was the last option on the command line 1629 and the command line contained at least two files and a target 1630 directory the first file will have logs appended to it. The -M 1631 option served little practical purpose in the last decade so its 1632 use is expected to be extremely rare. 1633 163420121223: 1635 After switching to Clang as the default compiler some users of ZFS 1636 on i386 systems started to experience stack overflow kernel panics. 1637 Please consider using 'options KSTACK_PAGES=4' in such configurations. 1638 163920121222: 1640 GEOM_LABEL now mangles label names read from file system metadata. 1641 Mangling affect labels containing spaces, non-printable characters, 1642 '%' or '"'. Device names in /etc/fstab and other places may need to 1643 be updated. 1644 164520121217: 1646 By default, only the 10 most recent kernel dumps will be saved. To 1647 restore the previous behaviour (no limit on the number of kernel dumps 1648 stored in the dump directory) add the following line to /etc/rc.conf: 1649 1650 savecore_flags="" 1651 165220121201: 1653 With the addition of auditdistd(8), a new auditdistd user is now 1654 required during installworld. "mergemaster -p" can be used to 1655 add the user prior to installworld, as documented in the handbook. 1656 165720121117: 1658 The sin6_scope_id member variable in struct sockaddr_in6 is now 1659 filled by the kernel before passing the structure to the userland via 1660 sysctl or routing socket. This means the KAME-specific embedded scope 1661 id in sin6_addr.s6_addr[2] is always cleared in userland application. 1662 This behavior can be controlled by net.inet6.ip6.deembed_scopeid. 1663 __FreeBSD_version is bumped to 1000025. 1664 166520121105: 1666 On i386 and amd64 systems WITH_CLANG_IS_CC is now the default. 1667 This means that the world and kernel will be compiled with clang 1668 and that clang will be installed as /usr/bin/cc, /usr/bin/c++, 1669 and /usr/bin/cpp. To disable this behavior and revert to building 1670 with gcc, compile with WITHOUT_CLANG_IS_CC. Really old versions 1671 of current may need to bootstrap WITHOUT_CLANG first if the clang 1672 build fails (its compatibility window doesn't extend to the 9 stable 1673 branch point). 1674 167520121102: 1676 The IPFIREWALL_FORWARD kernel option has been removed. Its 1677 functionality now turned on by default. 1678 167920121023: 1680 The ZERO_COPY_SOCKET kernel option has been removed and 1681 split into SOCKET_SEND_COW and SOCKET_RECV_PFLIP. 1682 NB: SOCKET_SEND_COW uses the VM page based copy-on-write 1683 mechanism which is not safe and may result in kernel crashes. 1684 NB: The SOCKET_RECV_PFLIP mechanism is useless as no current 1685 driver supports disposeable external page sized mbuf storage. 1686 Proper replacements for both zero-copy mechanisms are under 1687 consideration and will eventually lead to complete removal 1688 of the two kernel options. 1689 169020121023: 1691 The IPv4 network stack has been converted to network byte 1692 order. The following modules need to be recompiled together 1693 with kernel: carp(4), divert(4), gif(4), siftr(4), gre(4), 1694 pf(4), ipfw(4), ng_ipfw(4), stf(4). 1695 169620121022: 1697 Support for non-MPSAFE filesystems was removed from VFS. The 1698 VFS_VERSION was bumped, all filesystem modules shall be 1699 recompiled. 1700 170120121018: 1702 All the non-MPSAFE filesystems have been disconnected from 1703 the build. The full list includes: codafs, hpfs, ntfs, nwfs, 1704 portalfs, smbfs, xfs. 1705 170620121016: 1707 The interface cloning API and ABI has changed. The following 1708 modules need to be recompiled together with kernel: 1709 ipfw(4), pfsync(4), pflog(4), usb(4), wlan(4), stf(4), 1710 vlan(4), disc(4), edsc(4), if_bridge(4), gif(4), tap(4), 1711 faith(4), epair(4), enc(4), tun(4), if_lagg(4), gre(4). 1712 171320121015: 1714 The sdhci driver was split in two parts: sdhci (generic SD Host 1715 Controller logic) and sdhci_pci (actual hardware driver). 1716 No kernel config modifications are required, but if you 1717 load sdhc as a module you must switch to sdhci_pci instead. 1718 171920121014: 1720 Import the FUSE kernel and userland support into base system. 1721 172220121013: 1723 The GNU sort(1) program has been removed since the BSD-licensed 1724 sort(1) has been the default for quite some time and no serious 1725 problems have been reported. The corresponding WITH_GNU_SORT 1726 knob has also gone. 1727 172820121006: 1729 The pfil(9) API/ABI for AF_INET family has been changed. Packet 1730 filtering modules: pf(4), ipfw(4), ipfilter(4) need to be recompiled 1731 with new kernel. 1732 173320121001: 1734 The net80211(4) ABI has been changed to allow for improved driver 1735 PS-POLL and power-save support. All wireless drivers need to be 1736 recompiled to work with the new kernel. 1737 173820120913: 1739 The random(4) support for the VIA hardware random number 1740 generator (`PADLOCK') is no longer enabled unconditionally. 1741 Add the padlock_rng device in the custom kernel config if 1742 needed. The GENERIC kernels on i386 and amd64 do include the 1743 device, so the change only affects the custom kernel 1744 configurations. 1745 174620120908: 1747 The pf(4) packet filter ABI has been changed. pfctl(8) and 1748 snmp_pf module need to be recompiled to work with new kernel. 1749 175020120828: 1751 A new ZFS feature flag "com.delphix:empty_bpobj" has been merged 1752 to -HEAD. Pools that have empty_bpobj in active state can not be 1753 imported read-write with ZFS implementations that do not support 1754 this feature. For more information read the zpool-features(5) 1755 manual page. 1756 175720120727: 1758 The sparc64 ZFS loader has been changed to no longer try to auto- 1759 detect ZFS providers based on diskN aliases but now requires these 1760 to be explicitly listed in the OFW boot-device environment variable. 1761 176220120712: 1763 The OpenSSL has been upgraded to 1.0.1c. Any binaries requiring 1764 libcrypto.so.6 or libssl.so.6 must be recompiled. Also, there are 1765 configuration changes. Make sure to merge /etc/ssl/openssl.cnf. 1766 176720120712: 1768 The following sysctls and tunables have been renamed for consistency 1769 with other variables: 1770 kern.cam.da.da_send_ordered -> kern.cam.da.send_ordered 1771 kern.cam.ada.ada_send_ordered -> kern.cam.ada.send_ordered 1772 177320120628: 1774 The sort utility has been replaced with BSD sort. For now, GNU sort 1775 is also available as "gnusort" or the default can be set back to 1776 GNU sort by setting WITH_GNU_SORT. In this case, BSD sort will be 1777 installed as "bsdsort". 1778 177920120611: 1780 A new version of ZFS (pool version 5000) has been merged to -HEAD. 1781 Starting with this version the old system of ZFS pool versioning 1782 is superseded by "feature flags". This concept enables forward 1783 compatibility against certain future changes in functionality of ZFS 1784 pools. The first read-only compatible "feature flag" for ZFS pools 1785 is named "com.delphix:async_destroy". For more information 1786 read the new zpool-features(5) manual page. 1787 Please refer to the "ZFS notes" section of this file for information 1788 on upgrading boot ZFS pools. 1789 179020120417: 1791 The malloc(3) implementation embedded in libc now uses sources imported 1792 as contrib/jemalloc. The most disruptive API change is to 1793 /etc/malloc.conf. If your system has an old-style /etc/malloc.conf, 1794 delete it prior to installworld, and optionally re-create it using the 1795 new format after rebooting. See malloc.conf(5) for details 1796 (specifically the TUNING section and the "opt.*" entries in the MALLCTL 1797 NAMESPACE section). 1798 179920120328: 1800 Big-endian MIPS TARGET_ARCH values no longer end in "eb". mips64eb 1801 is now spelled mips64. mipsn32eb is now spelled mipsn32. mipseb is 1802 now spelled mips. This is to aid compatibility with third-party 1803 software that expects this naming scheme in uname(3). Little-endian 1804 settings are unchanged. If you are updating a big-endian mips64 machine 1805 from before this change, you may need to set MACHINE_ARCH=mips64 in 1806 your environment before the new build system will recognize your machine. 1807 180820120306: 1809 Disable by default the option VFS_ALLOW_NONMPSAFE for all supported 1810 platforms. 1811 181220120229: 1813 Now unix domain sockets behave "as expected" on nullfs(5). Previously 1814 nullfs(5) did not pass through all behaviours to the underlying layer, 1815 as a result if we bound to a socket on the lower layer we could connect 1816 only to the lower path; if we bound to the upper layer we could connect 1817 only to the upper path. The new behavior is one can connect to both the 1818 lower and the upper paths regardless what layer path one binds to. 1819 182020120211: 1821 The getifaddrs upgrade path broken with 20111215 has been restored. 1822 If you have upgraded in between 20111215 and 20120209 you need to 1823 recompile libc again with your kernel. You still need to recompile 1824 world to be able to configure CARP but this restriction already 1825 comes from 20111215. 1826 182720120114: 1828 The set_rcvar() function has been removed from /etc/rc.subr. All 1829 base and ports rc.d scripts have been updated, so if you have a 1830 port installed with a script in /usr/local/etc/rc.d you can either 1831 hand-edit the rcvar= line, or reinstall the port. 1832 1833 An easy way to handle the mass-update of /etc/rc.d: 1834 rm /etc/rc.d/* && mergemaster -i 1835 183620120109: 1837 panic(9) now stops other CPUs in the SMP systems, disables interrupts 1838 on the current CPU and prevents other threads from running. 1839 This behavior can be reverted using the kern.stop_scheduler_on_panic 1840 tunable/sysctl. 1841 The new behavior can be incompatible with kern.sync_on_panic. 1842 184320111215: 1844 The carp(4) facility has been changed significantly. Configuration 1845 of the CARP protocol via ifconfig(8) has changed, as well as format 1846 of CARP events submitted to devd(8) has changed. See manual pages 1847 for more information. The arpbalance feature of carp(4) is currently 1848 not supported anymore. 1849 1850 Size of struct in_aliasreq, struct in6_aliasreq has changed. User 1851 utilities using SIOCAIFADDR, SIOCAIFADDR_IN6, e.g. ifconfig(8), 1852 need to be recompiled. 1853 185420111122: 1855 The acpi_wmi(4) status device /dev/wmistat has been renamed to 1856 /dev/wmistat0. 1857 185820111108: 1859 The option VFS_ALLOW_NONMPSAFE option has been added in order to 1860 explicitely support non-MPSAFE filesystems. 1861 It is on by default for all supported platform at this present 1862 time. 1863 186420111101: 1865 The broken amd(4) driver has been replaced with esp(4) in the amd64, 1866 i386 and pc98 GENERIC kernel configuration files. 1867 186820110930: 1869 sysinstall has been removed 1870 187120110923: 1872 The stable/9 branch created in subversion. This corresponds to the 1873 RELENG_9 branch in CVS. 1874 1875COMMON ITEMS: 1876 1877 General Notes 1878 ------------- 1879 Avoid using make -j when upgrading. While generally safe, there are 1880 sometimes problems using -j to upgrade. If your upgrade fails with 1881 -j, please try again without -j. From time to time in the past there 1882 have been problems using -j with buildworld and/or installworld. This 1883 is especially true when upgrading between "distant" versions (eg one 1884 that cross a major release boundary or several minor releases, or when 1885 several months have passed on the -current branch). 1886 1887 Sometimes, obscure build problems are the result of environment 1888 poisoning. This can happen because the make utility reads its 1889 environment when searching for values for global variables. To run 1890 your build attempts in an "environmental clean room", prefix all make 1891 commands with 'env -i '. See the env(1) manual page for more details. 1892 1893 When upgrading from one major version to another it is generally best to 1894 upgrade to the latest code in the currently installed branch first, then 1895 do an upgrade to the new branch. This is the best-tested upgrade path, 1896 and has the highest probability of being successful. Please try this 1897 approach if you encounter problems with a major version upgrade. Since 1898 the stable 4.x branch point, one has generally been able to upgrade from 1899 anywhere in the most recent stable branch to head / current (or even the 1900 last couple of stable branches). See the top of this file when there's 1901 an exception. 1902 1903 When upgrading a live system, having a root shell around before 1904 installing anything can help undo problems. Not having a root shell 1905 around can lead to problems if pam has changed too much from your 1906 starting point to allow continued authentication after the upgrade. 1907 1908 This file should be read as a log of events. When a later event changes 1909 information of a prior event, the prior event should not be deleted. 1910 Instead, a pointer to the entry with the new information should be 1911 placed in the old entry. Readers of this file should also sanity check 1912 older entries before relying on them blindly. Authors of new entries 1913 should write them with this in mind. 1914 1915 ZFS notes 1916 --------- 1917 When upgrading the boot ZFS pool to a new version, always follow 1918 these two steps: 1919 1920 1.) recompile and reinstall the ZFS boot loader and boot block 1921 (this is part of "make buildworld" and "make installworld") 1922 1923 2.) update the ZFS boot block on your boot drive 1924 1925 The following example updates the ZFS boot block on the first 1926 partition (freebsd-boot) of a GPT partitioned drive ada0: 1927 "gpart bootcode -p /boot/gptzfsboot -i 1 ada0" 1928 1929 Non-boot pools do not need these updates. 1930 1931 To build a kernel 1932 ----------------- 1933 If you are updating from a prior version of FreeBSD (even one just 1934 a few days old), you should follow this procedure. It is the most 1935 failsafe as it uses a /usr/obj tree with a fresh mini-buildworld, 1936 1937 make kernel-toolchain 1938 make -DALWAYS_CHECK_MAKE buildkernel KERNCONF=YOUR_KERNEL_HERE 1939 make -DALWAYS_CHECK_MAKE installkernel KERNCONF=YOUR_KERNEL_HERE 1940 1941 To test a kernel once 1942 --------------------- 1943 If you just want to boot a kernel once (because you are not sure 1944 if it works, or if you want to boot a known bad kernel to provide 1945 debugging information) run 1946 make installkernel KERNCONF=YOUR_KERNEL_HERE KODIR=/boot/testkernel 1947 nextboot -k testkernel 1948 1949 To rebuild everything and install it on the current system. 1950 ----------------------------------------------------------- 1951 # Note: sometimes if you are running current you gotta do more than 1952 # is listed here if you are upgrading from a really old current. 1953 1954 <make sure you have good level 0 dumps> 1955 make buildworld 1956 make buildkernel KERNCONF=YOUR_KERNEL_HERE 1957 make installkernel KERNCONF=YOUR_KERNEL_HERE 1958 [1] 1959 <reboot in single user> [3] 1960 mergemaster -Fp [5] 1961 make installworld 1962 mergemaster -Fi [4] 1963 make delete-old [6] 1964 <reboot> 1965 1966 To cross-install current onto a separate partition 1967 -------------------------------------------------- 1968 # In this approach we use a separate partition to hold 1969 # current's root, 'usr', and 'var' directories.

At this point in the life 2005 cycle of current, things change often and you are on your own 2006 to cope. The defaults can also change, so please read ALL of 2007 the UPDATING entries. 2008 2009 Also, if you are tracking -current, you must be subscribed to 2010 freebsd-current@freebsd.org. Make sure that before you update 2011 your sources that you have read and understood all the recent 2012 messages there. If in doubt, please track -stable which has 2013 much fewer pitfalls. 2014 2015 [1] If you have third party modules, such as vmware, you 2016 should disable them at this point so they don't crash your 2017 system on reboot. 2018 2019 [3] From the bootblocks, boot -s, and then do 2020 fsck -p 2021 mount -u / 2022 mount -a 2023 cd src 2024 adjkerntz -i # if CMOS is wall time 2025 Also, when doing a major release upgrade, it is required that 2026 you boot into single user mode to do the installworld. 2027 2028 [4] Note: This step is non-optional. Failure to do this step 2029 can result in a significant reduction in the functionality of the 2030 system. Attempting to do it by hand is not recommended and those 2031 that pursue this avenue should read this file carefully, as well 2032 as the archives of freebsd-current and freebsd-hackers mailing lists 2033 for potential gotchas. The -U option is also useful to consider. 2034 See mergemaster(8) for more information. 2035 2036 [5] Usually this step is a no-op. However, from time to time 2037 you may need to do this if you get unknown user in the following 2038 step. It never hurts to do it all the time. You may need to 2039 install a new mergemaster (cd src/usr.sbin/mergemaster && make 2040 install) after the buildworld before this step if you last updated 2041 from current before 20130425 or from -stable before 20130430. 2042 2043 [6] This only deletes old files and directories. Old libraries 2044 can be deleted by "make delete-old-libs", but you have to make 2045 sure that no program is using those libraries anymore. 2046 2047 [8] In order to have a kernel that can run the 4.x binaries needed to 2048 do an installworld, you must include the COMPAT_FREEBSD4 option in 2049 your kernel. Failure to do so may leave you with a system that is 2050 hard to boot to recover. A similar kernel option COMPAT_FREEBSD5 is 2051 required to run the 5.x binaries on more recent kernels. And so on 2052 for COMPAT_FREEBSD6 and COMPAT_FREEBSD7. 2053 2054 Make sure that you merge any new devices from GENERIC since the 2055 last time you updated your kernel config file. 2056 2057 [9] If CPUTYPE is defined in your /etc/make.conf, make sure to use the 2058 "?=" instead of the "=" assignment operator, so that buildworld can 2059 override the CPUTYPE if it needs to. 2060 2061 MAKEOBJDIRPREFIX must be defined in an environment variable, and 2062 not on the command line, or in /etc/make.conf. buildworld will 2063 warn if it is improperly defined. 2064FORMAT: 2065 2066This file contains a list, in reverse chronological order, of major 2067breakages in tracking -current. It is not guaranteed to be a complete 2068list of such breakages, and only contains entries since September 23, 2011. 2069If you need to see UPDATING entries from before that date, you will need 2070to fetch an UPDATING file from an older FreeBSD release. 2071 2072Copyright information: 2073 2074Copyright 1998-2009 M.
