UPDATING revision 344455
1Updating Information for FreeBSD current users. 2 3This file is maintained and copyrighted by M. Warner Losh <imp@freebsd.org>. 4See end of file for further details. For commonly done items, please see the 5COMMON ITEMS: section later in the file. These instructions assume that you 6basically know what you are doing. If not, then please consult the FreeBSD 7handbook: 8 9 https://www.freebsd.org/doc/en_US.ISO8859-1/books/handbook/makeworld.html 10 11Items affecting the ports and packages system can be found in 12/usr/ports/UPDATING. Please read that file before running portupgrade. 13 14NOTE: FreeBSD has switched from gcc to clang. If you have trouble bootstrapping 15from older versions of FreeBSD, try WITHOUT_CLANG and WITH_GCC to bootstrap to 16the tip of head, and then rebuild without this option. The bootstrap process 17from older version of current across the gcc/clang cutover is a bit fragile. 18 1920190220: 20 Co-existance for Forth and Lua interpreters in bootloaders has now been 21 merged to ease testing of lualoader. LOADER_DEFAULT_INTERP, documented 22 in build(7), may be used to control which interpreter flavor is used in 23 the default loader to be installed. For systems where Lua and Forth 24 coexist, this switch can also be made on a running system by creating a 25 link from /boot/loader{,.efi} to /boot/loader_${flavor}{,efi} rather 26 than requiring a rebuild. 27 28 The default flavor in this branch will remain Forth. As indicated in 29 the 20190216 UPDATING entry, booting is a complex environment; it would 30 be prudent to assume that lualoader may not work for your setup and make 31 provisions for backup boot methods. 32 3320190220: 34 zfsloader's functionality has now been folded into loader. 35 zfsloader is no longer necesasary once you've updated your 36 boot blocks. For a transition period, we will install a 37 hardlink for zfsloader to loader to allow a smooth transition 38 until the boot blocks can be updated (hard link because old 39 zfs boot blocks don't understand symlinks). 40 4120190216: 42 Lualoader has been merged to facilitate testing on this branch. It's 43 purely opt-in for now by building WITH_LOADER_LUA and WITHOUT_FORTH in 44 /etc/src.conf, but co-existance will come shortly. Booting is a complex 45 environment and test coverage for Lua-enabled loaders has been thin, so 46 it would be prudent to assume it might not work and make provisions for 47 backup boot methods. 48 4920190216: 50 Clang, llvm, lld, lldb, compiler-rt and libc++ have been upgraded to 51 7.0.1. Please see the 20141231 entry below for information about 52 prerequisites and upgrading, if you are not already using clang 3.5.0 53 or higher. 54 5520181228: 56 r342562 modifies the NFSv4 server so that it obeys vfs.nfsd.nfs_privport 57 in the same as it is applied to NFSv2 and 3. This implies that NFSv4 58 servers that have vfs.nfsd.nfs_privport set will only allow mounts 59 from clients using a reserved port#. Since both the FreeBSD and Linux 60 NFSv4 clients use reserved port#s by default, this should not affect 61 most NFSv4 mounts. 62 6320181107: 64 The '%I' format in the kern.corefile sysctl limits the number of 65 core files that a process can generate to the number stored in the 66 debug.ncores sysctl. The '%I' format is replaced by the single digit 67 index. Previously, if all indexes were taken the kernel would overwrite 68 only a core file with the highest index in a filename. 69 Currently the system will create a new core file if there is a free 70 index or if all slots are taken it will overwrite the oldest one. 71 7220180818: 73 WITH_OFED option now only enables the build for the OFED libraries 74 and some fundamental client utilities. OpenSM and rest of the 75 debugging tools are enabled by WITH_OFED_EXTRA build switch. 76 WITH_OFED is turned on by default on amd64. 77 7820180714: 79 Clang, llvm, lld, lldb, compiler-rt and libc++ have been upgraded to 80 6.0.1. Please see the 20141231 entry below for information about 81 prerequisites and upgrading, if you are not already using clang 3.5.0 82 or higher. 83 8420180601: 85 The releng/11.2 branch has been created from stable/11@r334458. 86 8720180504: 88 The tz database (tzdb) has been updated to 2018e. This version more 89 correctly models time stamps in time zones with negative DST such as 90 Europe/Dublin (from 1971 on), Europe/Prague (1946/7), and 91 Africa/Windhoek (1994/2017). This does not affect the UT offsets, only 92 time zone abbreviations and the tm_isdst flag. 93 9420180409: 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 10220180331: 103 Clang, llvm, lld, lldb, compiler-rt and libc++ have been upgraded to 104 6.0.0. Please see the 20141231 entry below for information about 105 prerequisites and upgrading, if you are not already using clang 3.5.0 106 or higher. 107 10820180211: 109 The LOADER_FIREWIRE_SUPPORT build variable as been renamed to 110 WITH/OUT_LOADER_FIREWIRE. LOADER_{NO_,}GELI_SUPPORT has been renamed 111 to WITH/OUT_LOADER_GELI. 112 11320180210: 114 The geli password typed at boot is now hidden. To restore the previous 115 behavior, see geli(8) for configuration options. 116 117 The SW_WATCHDOG option is no longer necessary to enable the 118 hardclock-based software watchdog if no hardware watchdog is 119 configured. As before, SW_WATCHDOG will cause the software 120 watchdog to be enabled even if a hardware watchdog is configured. 121 12220180108: 123 lint(1) binaries and library are no longer built by default. To 124 enable building them, define WITH_LINT in src.conf. If you are using 125 a FreeBSD 12 or later system to build 11-stable, you may need to 126 install a lint(1) binary to use WITH_LINT. 127 12820171003: 129 When building multiple kernels using KERNCONF, non-existent KERNCONF 130 files will produce an error and buildkernel will fail. Previously 131 missing KERNCONF files silently failed giving no indication as to 132 why, only to subsequently discover during installkernel that the 133 desired kernel was never built in the first place. 134 13520170926: 136 Clang, llvm, lldb, compiler-rt and libc++ have been upgraded to 5.0.0. 137 Please see the 20141231 entry below for information about prerequisites 138 and upgrading, if you are not already using clang 3.5.0 or higher. 139 14020170822: 141 Since the switch to GPT disk labels, fsck for UFS/FFS has been 142 unable to automatically find alternate superblocks. As of r322806, 143 the information needed to find alternate superblocks has been 144 moved to the end of the area reserved for the boot block. 145 Filesystems created with a newfs of this vintage or later 146 will create the recovery information. If you have a filesystem 147 created prior to this change and wish to have a recovery block 148 created for your filesystem, you can do so by running fsck in 149 forground mode (i.e., do not use the -p or -y options). As it 150 starts, fsck will ask ``SAVE DATA TO FIND ALTERNATE SUPERBLOCKS'' 151 to which you should answer yes. 152 15320170629: 154 The releng/11.1 branch has been created from stable/11@r320475. 155 15620170518: 157 arm64 builds now use the base system LLD 4.0.0 linker by default, 158 instead of requiring that the aarch64-binutils port or package be 159 installed. To continue using aarch64-binutils, set 160 CROSS_BINUTILS_PREFIX=/usr/local/aarch64-freebsd/bin . 161 16220170529: 163 The ctl.ko module no longer implements the iSCSI target frontend: 164 cfiscsi.ko does instead. 165 166 If building cfiscsi.ko as a kernel module, the module can be loaded 167 via one of the following methods: 168 - `cfiscsi_load="YES"` in loader.conf(5). 169 - Add `cfiscsi` to `$kld_list` in rc.conf(5). 170 - ctladm(8)/ctld(8), when compiled with iSCSI support 171 (`WITH_ISCSI=yes` in src.conf(5)) 172 173 Please see cfiscsi(4) for more details. 174 17520170511: 176 The mmcsd.ko module now additionally depends on geom_flashmap.ko. 177 Also, mmc.ko and mmcsd.ko need to be a matching pair built from the 178 same source (previously, the dependency of mmcsd.ko on mmc.ko was 179 missing, but mmcsd.ko now will refuse to load if it is incompatible 180 with mmc.ko). 181 18220170414: 183 Binds and sends to the loopback addresses, IPv6 and IPv4, will now 184 use any explicitly assigned loopback address available in the jail 185 instead of using the first assigned address of the jail. 186 18720170413: 188 As of r316810 for ipfilter, keep frags is no longer assumed when 189 keep state is specified in a rule. r316810 aligns ipfilter with 190 documentation in man pages separating keep frags from keep state. 191 This allows keep state to specified without forcing keep frags 192 and allows keep frags to be specified independently of keep state. 193 To maintain previous behaviour, also specify keep frags with 194 keep state (as documented in ipf.conf.5). 195 19620170402: 197 Clang, llvm, lldb, compiler-rt and libc++ have been upgraded to 4.0.0. 198 Please see the 20141231 entry below for information about prerequisites 199 and upgrading, if you are not already using clang 3.5.0 or higher. 200 20120170323: 202 The code that provides support for ZFS .zfs/ directory functionality 203 has been reimplemented. It's not possible now to create a snapshot 204 by mkdir under .zfs/snapshot/. That should be the only user visible 205 change. 206 20720170319: 208 Many changes in the IPsec code have been merged from the FreeBSD-CURRENT 209 branch. The IPSEC_FILTERTUNNEL kernel option is removed in favour of 210 corresponding sysctl. The IPSEC_NAT_T kernel option is also removed, 211 and now NAT-T is supported by default. Security associations now use 212 the single namespace for SPI allocation, so if you use several manually 213 configured security associations with the same SPI, this configuration 214 needs modification. 215 21620161217: 217 Clang, llvm, lldb, compiler-rt and libc++ have been upgraded to 3.9.1. 218 Please see the 20141231 entry below for information about prerequisites 219 and upgrading, if you are not already using clang 3.5.0 or higher. 220 22120161124: 222 Clang, llvm, lldb, compiler-rt and libc++ have been upgraded to 3.9.0. 223 Please see the 20141231 entry below for information about prerequisites 224 and upgrading, if you are not already using clang 3.5.0 or higher. 225 22620161119: 227 The layout of the pmap structure has changed for powerpc to put the pmap 228 statistics at the front for all CPU variations. libkvm(3) and all tools 229 that link against it need to be recompiled. 230 23120161030: 232 isl(4) and cyapa(4) drivers now require a new driver, 233 chromebook_platform(4), to work properly on Chromebook-class hardware. 234 On other types of hardware the drivers may need to be configured using 235 device hints. Please see the corresponding manual pages for details. 236 23720161210: 238 Relocatable object files with the extension of .So have been renamed 239 to use an extension of .pico instead. The purpose of this change is 240 to avoid a name clash with shared libraries on case-insensitive file 241 systems. On those file systems, foo.So is the same file as foo.so. 242 24320160811: 244 The releng/11.0 branch has been created from stable/11@r303970. 245 24620160708: 247 The stable/11 branch has been created from head@r302406. 248 24920160622: 250 The libc stub for the pipe(2) system call has been replaced with 251 a wrapper that calls the pipe2(2) system call and the pipe(2) 252 system call is now only implemented by the kernels that include 253 "options COMPAT_FREEBSD10" in their config file (this is the 254 default). Users should ensure that this option is enabled in 255 their kernel or upgrade userspace to r302092 before upgrading their 256 kernel. 257 25820160527: 259 CAM will now strip leading spaces from SCSI disks' serial numbers. 260 This will effect users who create UFS filesystems on SCSI disks using 261 those disk's diskid device nodes. For example, if /etc/fstab 262 previously contained a line like 263 "/dev/diskid/DISK-%20%20%20%20%20%20%20ABCDEFG0123456", you should 264 change it to "/dev/diskid/DISK-ABCDEFG0123456". Users of geom 265 transforms like gmirror may also be affected. ZFS users should 266 generally be fine. 267 26820160523: 269 The bitstring(3) API has been updated with new functionality and 270 improved performance. But it is binary-incompatible with the old API. 271 Objects built with the new headers may not be linked against objects 272 built with the old headers. 273 27420160520: 275 The brk and sbrk functions have been removed from libc on arm64. 276 Binutils from ports has been updated to not link to these 277 functions and should be updated to the latest version before 278 installing a new libc. 279 28020160517: 281 The armv6 port now defaults to hard float ABI. Limited support 282 for running both hardfloat and soft float on the same system 283 is available using the libraries installed with -DWITH_LIBSOFT. 284 This has only been tested as an upgrade path for installworld 285 and packages may fail or need manual intervention to run. New 286 packages will be needed. 287 288 To update an existing self-hosted armv6hf system, you must add 289 TARGET_ARCH=armv6 on the make command line for both the build 290 and the install steps. 291 29220160510: 293 Kernel modules compiled outside of a kernel build now default to 294 installing to /boot/modules instead of /boot/kernel. Many kernel 295 modules built this way (such as those in ports) already overrode 296 KMODDIR explicitly to install into /boot/modules. However, 297 manually building and installing a module from /sys/modules will 298 now install to /boot/modules instead of /boot/kernel. 299 30020160414: 301 The CAM I/O scheduler has been committed to the kernel. There should be 302 no user visible impact. This does enable NCQ Trim on ada SSDs. While the 303 list of known rogues that claim support for this but actually corrupt 304 data is believed to be complete, be on the lookout for data 305 corruption. The known rogue list is believed to be complete: 306 307 o Crucial MX100, M550 drives with MU01 firmware. 308 o Micron M510 and M550 drives with MU01 firmware. 309 o Micron M500 prior to MU07 firmware 310 o Samsung 830, 840, and 850 all firmwares 311 o FCCT M500 all firmwares 312 313 Crucial has firmware http://www.crucial.com/usa/en/support-ssd-firmware 314 with working NCQ TRIM. For Micron branded drives, see your sales rep for 315 updated firmware. Black listed drives will work correctly because these 316 drives work correctly so long as no NCQ TRIMs are sent to them. Given 317 this list is the same as found in Linux, it's believed there are no 318 other rogues in the market place. All other models from the above 319 vendors work. 320 321 To be safe, if you are at all concerned, you can quirk each of your 322 drives to prevent NCQ from being sent by setting: 323 kern.cam.ada.X.quirks="0x2" 324 in loader.conf. If the drive requires the 4k sector quirk, set the 325 quirks entry to 0x3. 326 32720160330: 328 The FAST_DEPEND build option has been removed and its functionality is 329 now the one true way. The old mkdep(1) style of 'make depend' has 330 been removed. See 20160311 for further details. 331 33220160317: 333 Resource range types have grown from unsigned long to uintmax_t. All 334 drivers, and anything using libdevinfo, need to be recompiled. 335 33620160311: 337 WITH_FAST_DEPEND is now enabled by default for in-tree and out-of-tree 338 builds. It no longer runs mkdep(1) during 'make depend', and the 339 'make depend' stage can safely be skipped now as it is auto ran 340 when building 'make all' and will generate all SRCS and DPSRCS before 341 building anything else. Dependencies are gathered at compile time with 342 -MF flags kept in separate .depend files per object file. Users should 343 run 'make cleandepend' once if using -DNO_CLEAN to clean out older 344 stale .depend files. 345 34620160306: 347 On amd64, clang 3.8.0 can now insert sections of type AMD64_UNWIND into 348 kernel modules. Therefore, if you load any kernel modules at boot time, 349 please install the boot loaders after you install the kernel, but before 350 rebooting, e.g.: 351 352 make buildworld 353 make kernel KERNCONF=YOUR_KERNEL_HERE 354 make -C sys/boot install 355 <reboot in single user> 356 357 Then follow the usual steps, described in the General Notes section, 358 below. 359 36020160305: 361 Clang, llvm, lldb and compiler-rt have been upgraded to 3.8.0. Please 362 see the 20141231 entry below for information about prerequisites and 363 upgrading, if you are not already using clang 3.5.0 or higher. 364 36520160301: 366 The AIO subsystem is now a standard part of the kernel. The 367 VFS_AIO kernel option and aio.ko kernel module have been removed. 368 Due to stability concerns, asynchronous I/O requests are only 369 permitted on sockets and raw disks by default. To enable 370 asynchronous I/O requests on all file types, set the 371 vfs.aio.enable_unsafe sysctl to a non-zero value. 372 37320160226: 374 The ELF object manipulation tool objcopy is now provided by the 375 ELF Tool Chain project rather than by GNU binutils. It should be a 376 drop-in replacement, with the addition of arm64 support. The 377 (temporary) src.conf knob WITHOUT_ELFCOPY_AS_OBJCOPY knob may be set 378 to obtain the GNU version if necessary. 379 38020160129: 381 Building ZFS pools on top of zvols is prohibited by default. That 382 feature has never worked safely; it's always been prone to deadlocks. 383 Using a zvol as the backing store for a VM guest's virtual disk will 384 still work, even if the guest is using ZFS. Legacy behavior can be 385 restored by setting vfs.zfs.vol.recursive=1. 386 38720160119: 388 The NONE and HPN patches has been removed from OpenSSH. They are 389 still available in the security/openssh-portable port. 390 39120160113: 392 With the addition of ypldap(8), a new _ypldap user is now required 393 during installworld. "mergemaster -p" can be used to add the user 394 prior to installworld, as documented in the handbook. 395 39620151216: 397 The tftp loader (pxeboot) now uses the option root-path directive. As a 398 consequence it no longer looks for a pxeboot.4th file on the tftp 399 server. Instead it uses the regular /boot infrastructure as with the 400 other loaders. 401 40220151211: 403 The code to start recording plug and play data into the modules has 404 been committed. While the old tools will properly build a new kernel, 405 a number of warnings about "unknown metadata record 4" will be produced 406 for an older kldxref. To avoid such warnings, make sure to rebuild 407 the kernel toolchain (or world). Make sure that you have r292078 or 408 later when trying to build 292077 or later before rebuilding. 409 41020151207: 411 Debug data files are now built by default with 'make buildworld' and 412 installed with 'make installworld'. This facilitates debugging but 413 requires more disk space both during the build and for the installed 414 world. Debug files may be disabled by setting WITHOUT_DEBUG_FILES=yes 415 in src.conf(5). 416 41720151130: 418 r291527 changed the internal interface between the nfsd.ko and 419 nfscommon.ko modules. As such, they must both be upgraded to-gether. 420 __FreeBSD_version has been bumped because of this. 421 42220151108: 423 Add support for unicode collation strings leads to a change of 424 order of files listed by ls(1) for example. To get back to the old 425 behaviour, set LC_COLLATE environment variable to "C". 426 427 Databases administrators will need to reindex their databases given 428 collation results will be different. 429 430 Due to a bug in install(1) it is recommended to remove the ancient 431 locales before running make installworld. 432 433 rm -rf /usr/share/locale/* 434 43520151030: 436 The OpenSSL has been upgraded to 1.0.2d. Any binaries requiring 437 libcrypto.so.7 or libssl.so.7 must be recompiled. 438 43920151020: 440 Qlogic 24xx/25xx firmware images were updated from 5.5.0 to 7.3.0. 441 Kernel modules isp_2400_multi and isp_2500_multi were removed and 442 should be replaced with isp_2400 and isp_2500 modules respectively. 443 44420151017: 445 The build previously allowed using 'make -n' to not recurse into 446 sub-directories while showing what commands would be executed, and 447 'make -n -n' to recursively show commands. Now 'make -n' will recurse 448 and 'make -N' will not. 449 45020151012: 451 If you specify SENDMAIL_MC or SENDMAIL_CF in make.conf, mergemaster 452 and etcupdate will now use this file. A custom sendmail.cf is now 453 updated via this mechanism rather than via installworld. If you had 454 excluded sendmail.cf in mergemaster.rc or etcupdate.conf, you may 455 want to remove the exclusion or change it to "always install". 456 /etc/mail/sendmail.cf is now managed the same way regardless of 457 whether SENDMAIL_MC/SENDMAIL_CF is used. If you are not using 458 SENDMAIL_MC/SENDMAIL_CF there should be no change in behavior. 459 46020151011: 461 Compatibility shims for legacy ATA device names have been removed. 462 It includes ATA_STATIC_ID kernel option, kern.cam.ada.legacy_aliases 463 and kern.geom.raid.legacy_aliases loader tunables, kern.devalias.* 464 environment variables, /dev/ad* and /dev/ar* symbolic links. 465 46620151006: 467 Clang, llvm, lldb, compiler-rt and libc++ have been upgraded to 3.7.0. 468 Please see the 20141231 entry below for information about prerequisites 469 and upgrading, if you are not already using clang 3.5.0 or higher. 470 47120150924: 472 Kernel debug files have been moved to /usr/lib/debug/boot/kernel/, 473 and renamed from .symbols to .debug. This reduces the size requirements 474 on the boot partition or file system and provides consistency with 475 userland debug files. 476 477 When using the supported kernel installation method the 478 /usr/lib/debug/boot/kernel directory will be renamed (to kernel.old) 479 as is done with /boot/kernel. 480 481 Developers wishing to maintain the historical behavior of installing 482 debug files in /boot/kernel/ can set KERN_DEBUGDIR="" in src.conf(5). 483 48420150827: 485 The wireless drivers had undergone changes that remove the 'parent 486 interface' from the ifconfig -l output. The rc.d network scripts 487 used to check presence of a parent interface in the list, so old 488 scripts would fail to start wireless networking. Thus, etcupdate(3) 489 or mergemaster(8) run is required after kernel update, to update your 490 rc.d scripts in /etc. 491 49220150827: 493 pf no longer supports 'scrub fragment crop' or 'scrub fragment drop-ovl' 494 These configurations are now automatically interpreted as 495 'scrub fragment reassemble'. 496 49720150817: 498 Kernel-loadable modules for the random(4) device are back. To use 499 them, the kernel must have 500 501 device random 502 options RANDOM_LOADABLE 503 504 kldload(8) can then be used to load random_fortuna.ko 505 or random_yarrow.ko. Please note that due to the indirect 506 function calls that the loadable modules need to provide, 507 the build-in variants will be slightly more efficient. 508 509 The random(4) kernel option RANDOM_DUMMY has been retired due to 510 unpopularity. It was not all that useful anyway. 511 51220150813: 513 The WITHOUT_ELFTOOLCHAIN_TOOLS src.conf(5) knob has been retired. 514 Control over building the ELF Tool Chain tools is now provided by 515 the WITHOUT_TOOLCHAIN knob. 516 51720150810: 518 The polarity of Pulse Per Second (PPS) capture events with the 519 uart(4) driver has been corrected. Prior to this change the PPS 520 "assert" event corresponded to the trailing edge of a positive PPS 521 pulse and the "clear" event was the leading edge of the next pulse. 522 523 As the width of a PPS pulse in a typical GPS receiver is on the 524 order of 1 millisecond, most users will not notice any significant 525 difference with this change. 526 527 Anyone who has compensated for the historical polarity reversal by 528 configuring a negative offset equal to the pulse width will need to 529 remove that workaround. 530 53120150809: 532 The default group assigned to /dev/dri entries has been changed 533 from 'wheel' to 'video' with the id of '44'. If you want to have 534 access to the dri devices please add yourself to the video group 535 with: 536 537 # pw groupmod video -m $USER 538 53920150806: 540 The menu.rc and loader.rc files will now be replaced during 541 upgrades. Please migrate local changes to menu.rc.local and 542 loader.rc.local instead. 543 54420150805: 545 GNU Binutils versions of addr2line, c++filt, nm, readelf, size, 546 strings and strip have been removed. The src.conf(5) knob 547 WITHOUT_ELFTOOLCHAIN_TOOLS no longer provides the binutils tools. 548 54920150728: 550 As ZFS requires more kernel stack pages than is the default on some 551 architectures e.g. i386, it now warns if KSTACK_PAGES is less than 552 ZFS_MIN_KSTACK_PAGES (which is 4 at the time of writing). 553 554 Please consider using 'options KSTACK_PAGES=X' where X is greater 555 than or equal to ZFS_MIN_KSTACK_PAGES i.e. 4 in such configurations. 556 55720150706: 558 sendmail has been updated to 8.15.2. Starting with FreeBSD 11.0 559 and sendmail 8.15, sendmail uses uncompressed IPv6 addresses by 560 default, i.e., they will not contain "::". For example, instead 561 of ::1, it will be 0:0:0:0:0:0:0:1. This permits a zero subnet 562 to have a more specific match, such as different map entries for 563 IPv6:0:0 vs IPv6:0. This change requires that configuration 564 data (including maps, files, classes, custom ruleset, etc.) must 565 use the same format, so make certain such configuration data is 566 upgrading. As a very simple check search for patterns like 567 'IPv6:[0-9a-fA-F:]*::' and 'IPv6::'. To return to the old 568 behavior, set the m4 option confUSE_COMPRESSED_IPV6_ADDRESSES or 569 the cf option UseCompressedIPv6Addresses. 570 57120150630: 572 The default kernel entropy-processing algorithm is now 573 Fortuna, replacing Yarrow. 574 575 Assuming you have 'device random' in your kernel config 576 file, the configurations allow a kernel option to override 577 this default. You may choose *ONE* of: 578 579 options RANDOM_YARROW # Legacy /dev/random algorithm. 580 options RANDOM_DUMMY # Blocking-only driver. 581 582 If you have neither, you get Fortuna. For most people, 583 read no further, Fortuna will give a /dev/random that works 584 like it always used to, and the difference will be irrelevant. 585 586 If you remove 'device random', you get *NO* kernel-processed 587 entropy at all. This may be acceptable to folks building 588 embedded systems, but has complications. Carry on reading, 589 and it is assumed you know what you need. 590 591 *PLEASE* read random(4) and random(9) if you are in the 592 habit of tweaking kernel configs, and/or if you are a member 593 of the embedded community, wanting specific and not-usual 594 behaviour from your security subsystems. 595 596 NOTE!! If you use RANDOM_DUMMY and/or have no 'device 597 random', you will NOT have a functioning /dev/random, and 598 many cryptographic features will not work, including SSH. 599 You may also find strange behaviour from the random(3) set 600 of library functions, in particular sranddev(3), srandomdev(3) 601 and arc4random(3). The reason for this is that the KERN_ARND 602 sysctl only returns entropy if it thinks it has some to 603 share, and with RANDOM_DUMMY or no 'device random' this 604 will never happen. 605 60620150623: 607 An additional fix for the issue described in the 20150614 sendmail 608 entry below has been been committed in revision 284717. 609 61020150616: 611 FreeBSD's old make (fmake) has been removed from the system. It is 612 available as the devel/fmake port or via pkg install fmake. 613 61420150615: 615 The fix for the issue described in the 20150614 sendmail entry 616 below has been been committed in revision 284436. The work 617 around described in that entry is no longer needed unless the 618 default setting is overridden by a confDH_PARAMETERS configuration 619 setting of '5' or pointing to a 512 bit DH parameter file. 620 62120150614: 622 ALLOW_DEPRECATED_ATF_TOOLS/ATFFILE support has been removed from 623 atf.test.mk (included from bsd.test.mk). Please upgrade devel/atf 624 and devel/kyua to version 0.20+ and adjust any calling code to work 625 with Kyuafile and kyua. 626 62720150614: 628 The import of openssl to address the FreeBSD-SA-15:10.openssl 629 security advisory includes a change which rejects handshakes 630 with DH parameters below 768 bits. sendmail releases prior 631 to 8.15.2 (not yet released), defaulted to a 512 bit 632 DH parameter setting for client connections. To work around 633 this interoperability, sendmail can be configured to use a 634 2048 bit DH parameter by: 635 636 1. Edit /etc/mail/`hostname`.mc 637 2. If a setting for confDH_PARAMETERS does not exist or 638 exists and is set to a string beginning with '5', 639 replace it with '2'. 640 3. If a setting for confDH_PARAMETERS exists and is set to 641 a file path, create a new file with: 642 openssl dhparam -out /path/to/file 2048 643 4. Rebuild the .cf file: 644 cd /etc/mail/; make; make install 645 5. Restart sendmail: 646 cd /etc/mail/; make restart 647 648 A sendmail patch is coming, at which time this file will be 649 updated. 650 65120150604: 652 Generation of legacy formatted entries have been disabled by default 653 in pwd_mkdb(8), as all base system consumers of the legacy formatted 654 entries were converted to use the new format by default when the new, 655 machine independent format have been added and supported since FreeBSD 656 5.x. 657 658 Please see the pwd_mkdb(8) manual page for further details. 659 66020150525: 661 Clang and llvm have been upgraded to 3.6.1 release. Please see the 662 20141231 entry below for information about prerequisites and upgrading, 663 if you are not already using 3.5.0 or higher. 664 66520150521: 666 TI platform code switched to using vendor DTS files and this update 667 may break existing systems running on Beaglebone, Beaglebone Black, 668 and Pandaboard: 669 670 - dtb files should be regenerated/reinstalled. Filenames are the 671 same but content is different now 672 - GPIO addressing was changed, now each GPIO bank (32 pins per bank) 673 has its own /dev/gpiocX device, e.g. pin 121 on /dev/gpioc0 in old 674 addressing scheme is now pin 25 on /dev/gpioc3. 675 - Pandaboard: /etc/ttys should be updated, serial console device is 676 now /dev/ttyu2, not /dev/ttyu0 677 67820150501: 679 soelim(1) from gnu/usr.bin/groff has been replaced by usr.bin/soelim. 680 If you need the GNU extension from groff soelim(1), install groff 681 from package: pkg install groff, or via ports: textproc/groff. 682 68320150423: 684 chmod, chflags, chown and chgrp now affect symlinks in -R mode as 685 defined in symlink(7); previously symlinks were silently ignored. 686 68720150415: 688 The const qualifier has been removed from iconv(3) to comply with 689 POSIX. The ports tree is aware of this from r384038 onwards. 690 69120150416: 692 Libraries specified by LIBADD in Makefiles must have a corresponding 693 DPADD_<lib> variable to ensure correct dependencies. This is now 694 enforced in src.libnames.mk. 695 69620150324: 697 From legacy ata(4) driver was removed support for SATA controllers 698 supported by more functional drivers ahci(4), siis(4) and mvs(4). 699 Kernel modules ataahci and ataadaptec were removed completely, 700 replaced by ahci and mvs modules respectively. 701 70220150315: 703 Clang, llvm and lldb have been upgraded to 3.6.0 release. Please see 704 the 20141231 entry below for information about prerequisites and 705 upgrading, if you are not already using 3.5.0 or higher. 706 70720150307: 708 The 32-bit PowerPC kernel has been changed to a position-independent 709 executable. This can only be booted with a version of loader(8) 710 newer than January 31, 2015, so make sure to update both world and 711 kernel before rebooting. 712 71320150217: 714 If you are running a -CURRENT kernel since r273872 (Oct 30th, 2014), 715 but before r278950, the RNG was not seeded properly. Immediately 716 upgrade the kernel to r278950 or later and regenerate any keys (e.g. 717 ssh keys or openssl keys) that were generated w/ a kernel from that 718 range. This does not affect programs that directly used /dev/random 719 or /dev/urandom. All userland uses of arc4random(3) are affected. 720 72120150210: 722 The autofs(4) ABI was changed in order to restore binary compatibility 723 with 10.1-RELEASE. The automountd(8) daemon needs to be rebuilt to work 724 with the new kernel. 725 72620150131: 727 The powerpc64 kernel has been changed to a position-independent 728 executable. This can only be booted with a new version of loader(8), 729 so make sure to update both world and kernel before rebooting. 730 73120150118: 732 Clang and llvm have been upgraded to 3.5.1 release. This is a bugfix 733 only release, no new features have been added. Please see the 20141231 734 entry below for information about prerequisites and upgrading, if you 735 are not already using 3.5.0. 736 73720150107: 738 ELF tools addr2line, elfcopy (strip), nm, size, and strings are now 739 taken from the ELF Tool Chain project rather than GNU binutils. They 740 should be drop-in replacements, with the addition of arm64 support. 741 The WITHOUT_ELFTOOLCHAIN_TOOLS= knob may be used to obtain the 742 binutils tools, if necessary. See 20150805 for updated information. 743 74420150105: 745 The default Unbound configuration now enables remote control 746 using a local socket. Users who have already enabled the 747 local_unbound service should regenerate their configuration 748 by running "service local_unbound setup" as root. 749 75020150102: 751 The GNU texinfo and GNU info pages have been removed. 752 To be able to view GNU info pages please install texinfo from ports. 753 75420141231: 755 Clang, llvm and lldb have been upgraded to 3.5.0 release. 756 757 As of this release, a prerequisite for building clang, llvm and lldb is 758 a C++11 capable compiler and C++11 standard library. This means that to 759 be able to successfully build the cross-tools stage of buildworld, with 760 clang as the bootstrap compiler, your system compiler or cross compiler 761 should either be clang 3.3 or later, or gcc 4.8 or later, and your 762 system C++ library should be libc++, or libdstdc++ from gcc 4.8 or 763 later. 764 765 On any standard FreeBSD 10.x or 11.x installation, where clang and 766 libc++ are on by default (that is, on x86 or arm), this should work out 767 of the box. 768 769 On 9.x installations where clang is enabled by default, e.g. on x86 and 770 powerpc, libc++ will not be enabled by default, so libc++ should be 771 built (with clang) and installed first. If both clang and libc++ are 772 missing, build clang first, then use it to build libc++. 773 774 On 8.x and earlier installations, upgrade to 9.x first, and then follow 775 the instructions for 9.x above. 776 777 Sparc64 and mips users are unaffected, as they still use gcc 4.2.1 by 778 default, and do not build clang. 779 780 Many embedded systems are resource constrained, and will not be able to 781 build clang in a reasonable time, or in some cases at all. In those 782 cases, cross building bootable systems on amd64 is a workaround. 783 784 This new version of clang introduces a number of new warnings, of which 785 the following are most likely to appear: 786 787 -Wabsolute-value 788 789 This warns in two cases, for both C and C++: 790 * When the code is trying to take the absolute value of an unsigned 791 quantity, which is effectively a no-op, and almost never what was 792 intended. The code should be fixed, if at all possible. If you are 793 sure that the unsigned quantity can be safely cast to signed, without 794 loss of information or undefined behavior, you can add an explicit 795 cast, or disable the warning. 796 797 * When the code is trying to take an absolute value, but the called 798 abs() variant is for the wrong type, which can lead to truncation. 799 If you want to disable the warning instead of fixing the code, please 800 make sure that truncation will not occur, or it might lead to unwanted 801 side-effects. 802 803 -Wtautological-undefined-compare and 804 -Wundefined-bool-conversion 805 806 These warn when C++ code is trying to compare 'this' against NULL, while 807 'this' should never be NULL in well-defined C++ code. However, there is 808 some legacy (pre C++11) code out there, which actively abuses this 809 feature, which was less strictly defined in previous C++ versions. 810 811 Squid and openjdk do this, for example. The warning can be turned off 812 for C++98 and earlier, but compiling the code in C++11 mode might result 813 in unexpected behavior; for example, the parts of the program that are 814 unreachable could be optimized away. 815 81620141222: 817 The old NFS client and server (kernel options NFSCLIENT, NFSSERVER) 818 kernel sources have been removed. The .h files remain, since some 819 utilities include them. This will need to be fixed later. 820 If "mount -t oldnfs ..." is attempted, it will fail. 821 If the "-o" option on mountd(8), nfsd(8) or nfsstat(1) is used, 822 the utilities will report errors. 823 82420141121: 825 The handling of LOCAL_LIB_DIRS has been altered to skip addition of 826 directories to top level SUBDIR variable when their parent 827 directory is included in LOCAL_DIRS. Users with build systems with 828 such hierarchies and without SUBDIR entries in the parent 829 directory Makefiles should add them or add the directories to 830 LOCAL_DIRS. 831 83220141109: 833 faith(4) and faithd(8) have been removed from the base system. Faith 834 has been obsolete for a very long time. 835 83620141104: 837 vt(4), the new console driver, is enabled by default. It brings 838 support for Unicode and double-width characters, as well as 839 support for UEFI and integration with the KMS kernel video 840 drivers. 841 842 You may need to update your console settings in /etc/rc.conf, 843 most probably the keymap. During boot, /etc/rc.d/syscons will 844 indicate what you need to do. 845 846 vt(4) still has issues and lacks some features compared to 847 syscons(4). See the wiki for up-to-date information: 848 https://wiki.freebsd.org/Newcons 849 850 If you want to keep using syscons(4), you can do so by adding 851 the following line to /boot/loader.conf: 852 kern.vty=sc 853 85420141102: 855 pjdfstest has been integrated into kyua as an opt-in test suite. 856 Please see share/doc/pjdfstest/README for more details on how to 857 execute it. 858 85920141009: 860 gperf has been removed from the base system for architectures 861 that use clang. Ports that require gperf will obtain it from the 862 devel/gperf port. 863 86420140923: 865 pjdfstest has been moved from tools/regression/pjdfstest to 866 contrib/pjdfstest . 867 86820140922: 869 At svn r271982, The default linux compat kernel ABI has been adjusted 870 to 2.6.18 in support of the linux-c6 compat ports infrastructure 871 update. If you wish to continue using the linux-f10 compat ports, 872 add compat.linux.osrelease=2.6.16 to your local sysctl.conf. Users are 873 encouraged to update their linux-compat packages to linux-c6 during 874 their next update cycle. 875 87620140729: 877 The ofwfb driver, used to provide a graphics console on PowerPC when 878 using vt(4), no longer allows mmap() of all physical memory. This 879 will prevent Xorg on PowerPC with some ATI graphics cards from 880 initializing properly unless x11-servers/xorg-server is updated to 881 1.12.4_8 or newer. 882 88320140723: 884 The xdev targets have been converted to using TARGET and 885 TARGET_ARCH instead of XDEV and XDEV_ARCH. 886 88720140719: 888 The default unbound configuration has been modified to address 889 issues with reverse lookups on networks that use private 890 address ranges. If you use the local_unbound service, run 891 "service local_unbound setup" as root to regenerate your 892 configuration, then "service local_unbound reload" to load the 893 new configuration. 894 89520140709: 896 The GNU texinfo and GNU info pages are not built and installed 897 anymore, WITH_INFO knob has been added to allow to built and install 898 them again. 899 UPDATE: see 20150102 entry on texinfo's removal 900 90120140708: 902 The GNU readline library is now an INTERNALLIB - that is, it is 903 statically linked into consumers (GDB and variants) in the base 904 system, and the shared library is no longer installed. The 905 devel/readline port is available for third party software that 906 requires readline. 907 90820140702: 909 The Itanium architecture (ia64) has been removed from the list of 910 known architectures. This is the first step in the removal of the 911 architecture. 912 91320140701: 914 Commit r268115 has added NFSv4.1 server support, merged from 915 projects/nfsv4.1-server. Since this includes changes to the 916 internal interfaces between the NFS related modules, a full 917 build of the kernel and modules will be necessary. 918 __FreeBSD_version has been bumped. 919 92020140629: 921 The WITHOUT_VT_SUPPORT kernel config knob has been renamed 922 WITHOUT_VT. (The other _SUPPORT knobs have a consistent meaning 923 which differs from the behaviour controlled by this knob.) 924 92520140619: 926 Maximal length of the serial number in CTL was increased from 16 to 927 64 chars, that breaks ABI. All CTL-related tools, such as ctladm 928 and ctld, need to be rebuilt to work with a new kernel. 929 93020140606: 931 The libatf-c and libatf-c++ major versions were downgraded to 0 and 932 1 respectively to match the upstream numbers. They were out of 933 sync because, when they were originally added to FreeBSD, the 934 upstream versions were not respected. These libraries are private 935 and not yet built by default, so renumbering them should be a 936 non-issue. However, unclean source trees will yield broken test 937 programs once the operator executes "make delete-old-libs" after a 938 "make installworld". 939 940 Additionally, the atf-sh binary was made private by moving it into 941 /usr/libexec/. Already-built shell test programs will keep the 942 path to the old binary so they will break after "make delete-old" 943 is run. 944 945 If you are using WITH_TESTS=yes (not the default), wipe the object 946 tree and rebuild from scratch to prevent spurious test failures. 947 This is only needed once: the misnumbered libraries and misplaced 948 binaries have been added to OptionalObsoleteFiles.inc so they will 949 be removed during a clean upgrade. 950 95120140512: 952 Clang and llvm have been upgraded to 3.4.1 release. 953 95420140508: 955 We bogusly installed src.opts.mk in /usr/share/mk. This file should 956 be removed to avoid issues in the future (and has been added to 957 ObsoleteFiles.inc). 958 95920140505: 960 /etc/src.conf now affects only builds of the FreeBSD src tree. In the 961 past, it affected all builds that used the bsd.*.mk files. The old 962 behavior was a bug, but people may have relied upon it. To get this 963 behavior back, you can .include /etc/src.conf from /etc/make.conf 964 (which is still global and isn't changed). This also changes the 965 behavior of incremental builds inside the tree of individual 966 directories. Set MAKESYSPATH to ".../share/mk" to do that. 967 Although this has survived make universe and some upgrade scenarios, 968 other upgrade scenarios may have broken. At least one form of 969 temporary breakage was fixed with MAKESYSPATH settings for buildworld 970 as well... In cases where MAKESYSPATH isn't working with this 971 setting, you'll need to set it to the full path to your tree. 972 973 One side effect of all this cleaning up is that bsd.compiler.mk 974 is no longer implicitly included by bsd.own.mk. If you wish to 975 use COMPILER_TYPE, you must now explicitly include bsd.compiler.mk 976 as well. 977 97820140430: 979 The lindev device has been removed since /dev/full has been made a 980 standard device. __FreeBSD_version has been bumped. 981 98220140424: 983 The knob WITHOUT_VI was added to the base system, which controls 984 building ex(1), vi(1), etc. Older releases of FreeBSD required ex(1) 985 in order to reorder files share/termcap and didn't build ex(1) as a 986 build tool, so building/installing with WITH_VI is highly advised for 987 build hosts for older releases. 988 989 This issue has been fixed in stable/9 and stable/10 in r277022 and 990 r276991, respectively. 991 99220140418: 993 The YES_HESIOD knob has been removed. It has been obsolete for 994 a decade. Please move to using WITH_HESIOD instead or your builds 995 will silently lack HESIOD. 996 99720140405: 998 The uart(4) driver has been changed with respect to its handling 999 of the low-level console. Previously the uart(4) driver prevented 1000 any process from changing the baudrate or the CLOCAL and HUPCL 1001 control flags. By removing the restrictions, operators can make 1002 changes to the serial console port without having to reboot. 1003 However, when getty(8) is started on the serial device that is 1004 associated with the low-level console, a misconfigured terminal 1005 line in /etc/ttys will now have a real impact. 1006 Before upgrading the kernel, make sure that /etc/ttys has the 1007 serial console device configured as 3wire without baudrate to 1008 preserve the previous behaviour. E.g: 1009 ttyu0 "/usr/libexec/getty 3wire" vt100 on secure 1010 101120140306: 1012 Support for libwrap (TCP wrappers) in rpcbind was disabled by default 1013 to improve performance. To re-enable it, if needed, run rpcbind 1014 with command line option -W. 1015 101620140226: 1017 Switched back to the GPL dtc compiler due to updates in the upstream 1018 dts files not being supported by the BSDL dtc compiler. You will need 1019 to rebuild your kernel toolchain to pick up the new compiler. Core dumps 1020 may result while building dtb files during a kernel build if you fail 1021 to do so. Set WITHOUT_GPL_DTC if you require the BSDL compiler. 1022 102320140216: 1024 Clang and llvm have been upgraded to 3.4 release. 1025 102620140216: 1027 The nve(4) driver has been removed. Please use the nfe(4) driver 1028 for NVIDIA nForce MCP Ethernet adapters instead. 1029 103020140212: 1031 An ABI incompatibility crept into the libc++ 3.4 import in r261283. 1032 This could cause certain C++ applications using shared libraries built 1033 against the previous version of libc++ to crash. The incompatibility 1034 has now been fixed, but any C++ applications or shared libraries built 1035 between r261283 and r261801 should be recompiled. 1036 103720140204: 1038 OpenSSH will now ignore errors caused by kernel lacking of Capsicum 1039 capability mode support. Please note that enabling the feature in 1040 kernel is still highly recommended. 1041 104220140131: 1043 OpenSSH is now built with sandbox support, and will use sandbox as 1044 the default privilege separation method. This requires Capsicum 1045 capability mode support in kernel. 1046 104720140128: 1048 The libelf and libdwarf libraries have been updated to newer 1049 versions from upstream. Shared library version numbers for 1050 these two libraries were bumped. Any ports or binaries 1051 requiring these two libraries should be recompiled. 1052 __FreeBSD_version is bumped to 1100006. 1053 105420140110: 1055 If a Makefile in a tests/ directory was auto-generating a Kyuafile 1056 instead of providing an explicit one, this would prevent such 1057 Makefile from providing its own Kyuafile in the future during 1058 NO_CLEAN builds. This has been fixed in the Makefiles but manual 1059 intervention is needed to clean an objdir if you use NO_CLEAN: 1060 # find /usr/obj -name Kyuafile | xargs rm -f 1061 106220131213: 1063 The behavior of gss_pseudo_random() for the krb5 mechanism 1064 has changed, for applications requesting a longer random string 1065 than produced by the underlying enctype's pseudo-random() function. 1066 In particular, the random string produced from a session key of 1067 enctype aes256-cts-hmac-sha1-96 or aes256-cts-hmac-sha1-96 will 1068 be different at the 17th octet and later, after this change. 1069 The counter used in the PRF+ construction is now encoded as a 1070 big-endian integer in accordance with RFC 4402. 1071 __FreeBSD_version is bumped to 1100004. 1072 107320131108: 1074 The WITHOUT_ATF build knob has been removed and its functionality 1075 has been subsumed into the more generic WITHOUT_TESTS. If you were 1076 using the former to disable the build of the ATF libraries, you 1077 should change your settings to use the latter. 1078 107920131025: 1080 The default version of mtree is nmtree which is obtained from 1081 NetBSD. The output is generally the same, but may vary 1082 slightly. If you found you need identical output adding 1083 "-F freebsd9" to the command line should do the trick. For the 1084 time being, the old mtree is available as fmtree. 1085 108620131014: 1087 libbsdyml has been renamed to libyaml and moved to /usr/lib/private. 1088 This will break ports-mgmt/pkg. Rebuild the port, or upgrade to pkg 1089 1.1.4_8 and verify bsdyml not linked in, before running "make 1090 delete-old-libs": 1091 # make -C /usr/ports/ports-mgmt/pkg build deinstall install clean 1092 or 1093 # pkg install pkg; ldd /usr/local/sbin/pkg | grep bsdyml 1094 109520131010: 1096 The stable/10 branch has been created in subversion from head 1097 revision r256279. 1098 109920131010: 1100 The rc.d/jail script has been updated to support jail(8) 1101 configuration file. The "jail_<jname>_*" rc.conf(5) variables 1102 for per-jail configuration are automatically converted to 1103 /var/run/jail.<jname>.conf before the jail(8) utility is invoked. 1104 This is transparently backward compatible. See below about some 1105 incompatibilities and rc.conf(5) manual page for more details. 1106 1107 These variables are now deprecated in favor of jail(8) configuration 1108 file. One can use "rc.d/jail config <jname>" command to generate 1109 a jail(8) configuration file in /var/run/jail.<jname>.conf without 1110 running the jail(8) utility. The default pathname of the 1111 configuration file is /etc/jail.conf and can be specified by 1112 using $jail_conf or $jail_<jname>_conf variables. 1113 1114 Please note that jail_devfs_ruleset accepts an integer at 1115 this moment. Please consider to rewrite the ruleset name 1116 with an integer. 1117 111820130930: 1119 BIND has been removed from the base system. If all you need 1120 is a local resolver, simply enable and start the local_unbound 1121 service instead. Otherwise, several versions of BIND are 1122 available in the ports tree. The dns/bind99 port is one example. 1123 1124 With this change, nslookup(1) and dig(1) are no longer in the base 1125 system. Users should instead use host(1) and drill(1) which are 1126 in the base system. Alternatively, nslookup and dig can 1127 be obtained by installing the dns/bind-tools port. 1128 112920130916: 1130 With the addition of unbound(8), a new unbound user is now 1131 required during installworld. "mergemaster -p" can be used to 1132 add the user prior to installworld, as documented in the handbook. 1133 113420130911: 1135 OpenSSH is now built with DNSSEC support, and will by default 1136 silently trust signed SSHFP records. This can be controlled with 1137 the VerifyHostKeyDNS client configuration setting. DNSSEC support 1138 can be disabled entirely with the WITHOUT_LDNS option in src.conf. 1139 114020130906: 1141 The GNU Compiler Collection and C++ standard library (libstdc++) 1142 are no longer built by default on platforms where clang is the system 1143 compiler. You can enable them with the WITH_GCC and WITH_GNUCXX 1144 options in src.conf. 1145 114620130905: 1147 The PROCDESC kernel option is now part of the GENERIC kernel 1148 configuration and is required for the rwhod(8) to work. 1149 If you are using custom kernel configuration, you should include 1150 'options PROCDESC'. 1151 115220130905: 1153 The API and ABI related to the Capsicum framework was modified 1154 in backward incompatible way. The userland libraries and programs 1155 have to be recompiled to work with the new kernel. This includes the 1156 following libraries and programs, but the whole buildworld is 1157 advised: libc, libprocstat, dhclient, tcpdump, hastd, hastctl, 1158 kdump, procstat, rwho, rwhod, uniq. 1159 116020130903: 1161 AES-NI intrinsic support has been added to gcc. The AES-NI module 1162 has been updated to use this support. A new gcc is required to build 1163 the aesni module on both i386 and amd64. 1164 116520130821: 1166 The PADLOCK_RNG and RDRAND_RNG kernel options are now devices. 1167 Thus "device padlock_rng" and "device rdrand_rng" should be 1168 used instead of "options PADLOCK_RNG" & "options RDRAND_RNG". 1169 117020130813: 1171 WITH_ICONV has been split into two feature sets. WITH_ICONV now 1172 enables just the iconv* functionality and is now on by default. 1173 WITH_LIBICONV_COMPAT enables the libiconv api and link time 1174 compatibility. Set WITHOUT_ICONV to build the old way. 1175 If you have been using WITH_ICONV before, you will very likely 1176 need to turn on WITH_LIBICONV_COMPAT. 1177 117820130806: 1179 INVARIANTS option now enables DEBUG for code with OpenSolaris and 1180 Illumos origin, including ZFS. If you have INVARIANTS in your 1181 kernel configuration, then there is no need to set DEBUG or ZFS_DEBUG 1182 explicitly. 1183 DEBUG used to enable witness(9) tracking of OpenSolaris (mostly ZFS) 1184 locks if WITNESS option was set. Because that generated a lot of 1185 witness(9) reports and all of them were believed to be false 1186 positives, this is no longer done. New option OPENSOLARIS_WITNESS 1187 can be used to achieve the previous behavior. 1188 118920130806: 1190 Timer values in IPv6 data structures now use time_uptime instead 1191 of time_second. Although this is not a user-visible functional 1192 change, userland utilities which directly use them---ndp(8), 1193 rtadvd(8), and rtsold(8) in the base system---need to be updated 1194 to r253970 or later. 1195 119620130802: 1197 find -delete can now delete the pathnames given as arguments, 1198 instead of only files found below them or if the pathname did 1199 not contain any slashes. Formerly, the following error message 1200 would result: 1201 1202 find: -delete: <path>: relative path potentially not safe 1203 1204 Deleting the pathnames given as arguments can be prevented 1205 without error messages using -mindepth 1 or by changing 1206 directory and passing "." as argument to find. This works in the 1207 old as well as the new version of find. 1208 120920130726: 1210 Behavior of devfs rules path matching has been changed. 1211 Pattern is now always matched against fully qualified devfs 1212 path and slash characters must be explicitly matched by 1213 slashes in pattern (FNM_PATHNAME). Rulesets involving devfs 1214 subdirectories must be reviewed. 1215 121620130716: 1217 The default ARM ABI has changed to the ARM EABI. The old ABI is 1218 incompatible with the ARM EABI and all programs and modules will 1219 need to be rebuilt to work with a new kernel. 1220 1221 To keep using the old ABI ensure the WITHOUT_ARM_EABI knob is set. 1222 1223 NOTE: Support for the old ABI will be removed in the future and 1224 users are advised to upgrade. 1225 122620130709: 1227 pkg_install has been disconnected from the build if you really need it 1228 you should add WITH_PKGTOOLS in your src.conf(5). 1229 123020130709: 1231 Most of network statistics structures were changed to be able 1232 keep 64-bits counters. Thus all tools, that work with networking 1233 statistics, must be rebuilt (netstat(1), bsnmpd(1), etc.) 1234 123520130618: 1236 Fix a bug that allowed a tracing process (e.g. gdb) to write 1237 to a memory-mapped file in the traced process's address space 1238 even if neither the traced process nor the tracing process had 1239 write access to that file. 1240 124120130615: 1242 CVS has been removed from the base system. An exact copy 1243 of the code is available from the devel/cvs port. 1244 124520130613: 1246 Some people report the following error after the switch to bmake: 1247 1248 make: illegal option -- J 1249 usage: make [-BPSXeiknpqrstv] [-C directory] [-D variable] 1250 ... 1251 *** [buildworld] Error code 2 1252 1253 this likely due to an old instance of make in 1254 ${MAKEPATH} (${MAKEOBJDIRPREFIX}${.CURDIR}/make.${MACHINE}) 1255 which src/Makefile will use that blindly, if it exists, so if 1256 you see the above error: 1257 1258 rm -rf `make -V MAKEPATH` 1259 1260 should resolve it. 1261 126220130516: 1263 Use bmake by default. 1264 Whereas before one could choose to build with bmake via 1265 -DWITH_BMAKE one must now use -DWITHOUT_BMAKE to use the old 1266 make. The goal is to remove these knobs for 10-RELEASE. 1267 1268 It is worth noting that bmake (like gmake) treats the command 1269 line as the unit of failure, rather than statements within the 1270 command line. Thus '(cd some/where && dosomething)' is safer 1271 than 'cd some/where; dosomething'. The '()' allows consistent 1272 behavior in parallel build. 1273 127420130429: 1275 Fix a bug that allows NFS clients to issue READDIR on files. 1276 127720130426: 1278 The WITHOUT_IDEA option has been removed because 1279 the IDEA patent expired. 1280 128120130426: 1282 The sysctl which controls TRIM support under ZFS has been renamed 1283 from vfs.zfs.trim_disable -> vfs.zfs.trim.enabled and has been 1284 enabled by default. 1285 128620130425: 1287 The mergemaster command now uses the default MAKEOBJDIRPREFIX 1288 rather than creating it's own in the temporary directory in 1289 order allow access to bootstrapped versions of tools such as 1290 install and mtree. When upgrading from version of FreeBSD where 1291 the install command does not support -l, you will need to 1292 install a new mergemaster command if mergemaster -p is required. 1293 This can be accomplished with the command (cd src/usr.sbin/mergemaster 1294 && make install). 1295 129620130404: 1297 Legacy ATA stack, disabled and replaced by new CAM-based one since 1298 FreeBSD 9.0, completely removed from the sources. Kernel modules 1299 atadisk and atapi*, user-level tools atacontrol and burncd are 1300 removed. Kernel option `options ATA_CAM` is now permanently enabled 1301 and removed. 1302 130320130319: 1304 SOCK_CLOEXEC and SOCK_NONBLOCK flags have been added to socket(2) 1305 and socketpair(2). Software, in particular Kerberos, may 1306 automatically detect and use these during building. The resulting 1307 binaries will not work on older kernels. 1308 130920130308: 1310 CTL_DISABLE has also been added to the sparc64 GENERIC (for further 1311 information, see the respective 20130304 entry). 1312 131320130304: 1314 Recent commits to callout(9) changed the size of struct callout, 1315 so the KBI is probably heavily disturbed. Also, some functions 1316 in callout(9)/sleep(9)/sleepqueue(9)/condvar(9) KPIs were replaced 1317 by macros. Every kernel module using it won't load, so rebuild 1318 is requested. 1319 1320 The ctl device has been re-enabled in GENERIC for i386 and amd64, 1321 but does not initialize by default (because of the new CTL_DISABLE 1322 option) to save memory. To re-enable it, remove the CTL_DISABLE 1323 option from the kernel config file or set kern.cam.ctl.disable=0 1324 in /boot/loader.conf. 1325 132620130301: 1327 The ctl device has been disabled in GENERIC for i386 and amd64. 1328 This was done due to the extra memory being allocated at system 1329 initialisation time by the ctl driver which was only used if 1330 a CAM target device was created. This makes a FreeBSD system 1331 unusable on 128MB or less of RAM. 1332 133320130208: 1334 A new compression method (lz4) has been merged to -HEAD. Please 1335 refer to zpool-features(7) for more information. 1336 1337 Please refer to the "ZFS notes" section of this file for information 1338 on upgrading boot ZFS pools. 1339 134020130129: 1341 A BSD-licensed patch(1) variant has been added and is installed 1342 as bsdpatch, being the GNU version the default patch. 1343 To inverse the logic and use the BSD-licensed one as default, 1344 while having the GNU version installed as gnupatch, rebuild 1345 and install world with the WITH_BSD_PATCH knob set. 1346 134720130121: 1348 Due to the use of the new -l option to install(1) during build 1349 and install, you must take care not to directly set the INSTALL 1350 make variable in your /etc/make.conf, /etc/src.conf, or on the 1351 command line. If you wish to use the -C flag for all installs 1352 you may be able to add INSTALL+=-C to /etc/make.conf or 1353 /etc/src.conf. 1354 135520130118: 1356 The install(1) option -M has changed meaning and now takes an 1357 argument that is a file or path to append logs to. In the 1358 unlikely event that -M was the last option on the command line 1359 and the command line contained at least two files and a target 1360 directory the first file will have logs appended to it. The -M 1361 option served little practical purpose in the last decade so its 1362 use is expected to be extremely rare. 1363 136420121223: 1365 After switching to Clang as the default compiler some users of ZFS 1366 on i386 systems started to experience stack overflow kernel panics. 1367 Please consider using 'options KSTACK_PAGES=4' in such configurations. 1368 136920121222: 1370 GEOM_LABEL now mangles label names read from file system metadata. 1371 Mangling affect labels containing spaces, non-printable characters, 1372 '%' or '"'. Device names in /etc/fstab and other places may need to 1373 be updated. 1374 137520121217: 1376 By default, only the 10 most recent kernel dumps will be saved. To 1377 restore the previous behaviour (no limit on the number of kernel dumps 1378 stored in the dump directory) add the following line to /etc/rc.conf: 1379 1380 savecore_flags="" 1381 138220121201: 1383 With the addition of auditdistd(8), a new auditdistd user is now 1384 required during installworld. "mergemaster -p" can be used to 1385 add the user prior to installworld, as documented in the handbook. 1386 138720121117: 1388 The sin6_scope_id member variable in struct sockaddr_in6 is now 1389 filled by the kernel before passing the structure to the userland via 1390 sysctl or routing socket. This means the KAME-specific embedded scope 1391 id in sin6_addr.s6_addr[2] is always cleared in userland application. 1392 This behavior can be controlled by net.inet6.ip6.deembed_scopeid. 1393 __FreeBSD_version is bumped to 1000025. 1394 139520121105: 1396 On i386 and amd64 systems WITH_CLANG_IS_CC is now the default. 1397 This means that the world and kernel will be compiled with clang 1398 and that clang will be installed as /usr/bin/cc, /usr/bin/c++, 1399 and /usr/bin/cpp. To disable this behavior and revert to building 1400 with gcc, compile with WITHOUT_CLANG_IS_CC. Really old versions 1401 of current may need to bootstrap WITHOUT_CLANG first if the clang 1402 build fails (its compatibility window doesn't extend to the 9 stable 1403 branch point). 1404 140520121102: 1406 The IPFIREWALL_FORWARD kernel option has been removed. Its 1407 functionality now turned on by default. 1408 140920121023: 1410 The ZERO_COPY_SOCKET kernel option has been removed and 1411 split into SOCKET_SEND_COW and SOCKET_RECV_PFLIP. 1412 NB: SOCKET_SEND_COW uses the VM page based copy-on-write 1413 mechanism which is not safe and may result in kernel crashes. 1414 NB: The SOCKET_RECV_PFLIP mechanism is useless as no current 1415 driver supports disposeable external page sized mbuf storage. 1416 Proper replacements for both zero-copy mechanisms are under 1417 consideration and will eventually lead to complete removal 1418 of the two kernel options. 1419 142020121023: 1421 The IPv4 network stack has been converted to network byte 1422 order. The following modules need to be recompiled together 1423 with kernel: carp(4), divert(4), gif(4), siftr(4), gre(4), 1424 pf(4), ipfw(4), ng_ipfw(4), stf(4). 1425 142620121022: 1427 Support for non-MPSAFE filesystems was removed from VFS. The 1428 VFS_VERSION was bumped, all filesystem modules shall be 1429 recompiled. 1430 143120121018: 1432 All the non-MPSAFE filesystems have been disconnected from 1433 the build. The full list includes: codafs, hpfs, ntfs, nwfs, 1434 portalfs, smbfs, xfs. 1435 143620121016: 1437 The interface cloning API and ABI has changed. The following 1438 modules need to be recompiled together with kernel: 1439 ipfw(4), pfsync(4), pflog(4), usb(4), wlan(4), stf(4), 1440 vlan(4), disc(4), edsc(4), if_bridge(4), gif(4), tap(4), 1441 faith(4), epair(4), enc(4), tun(4), if_lagg(4), gre(4). 1442 144320121015: 1444 The sdhci driver was split in two parts: sdhci (generic SD Host 1445 Controller logic) and sdhci_pci (actual hardware driver). 1446 No kernel config modifications are required, but if you 1447 load sdhc as a module you must switch to sdhci_pci instead. 1448 144920121014: 1450 Import the FUSE kernel and userland support into base system. 1451 145220121013: 1453 The GNU sort(1) program has been removed since the BSD-licensed 1454 sort(1) has been the default for quite some time and no serious 1455 problems have been reported. The corresponding WITH_GNU_SORT 1456 knob has also gone. 1457 145820121006: 1459 The pfil(9) API/ABI for AF_INET family has been changed. Packet 1460 filtering modules: pf(4), ipfw(4), ipfilter(4) need to be recompiled 1461 with new kernel. 1462 146320121001: 1464 The net80211(4) ABI has been changed to allow for improved driver 1465 PS-POLL and power-save support. All wireless drivers need to be 1466 recompiled to work with the new kernel. 1467 146820120913: 1469 The random(4) support for the VIA hardware random number 1470 generator (`PADLOCK') is no longer enabled unconditionally. 1471 Add the padlock_rng device in the custom kernel config if 1472 needed. The GENERIC kernels on i386 and amd64 do include the 1473 device, so the change only affects the custom kernel 1474 configurations. 1475 147620120908: 1477 The pf(4) packet filter ABI has been changed. pfctl(8) and 1478 snmp_pf module need to be recompiled to work with new kernel. 1479 148020120828: 1481 A new ZFS feature flag "com.delphix:empty_bpobj" has been merged 1482 to -HEAD. Pools that have empty_bpobj in active state can not be 1483 imported read-write with ZFS implementations that do not support 1484 this feature. For more information read the zpool-features(5) 1485 manual page. 1486 148720120727: 1488 The sparc64 ZFS loader has been changed to no longer try to auto- 1489 detect ZFS providers based on diskN aliases but now requires these 1490 to be explicitly listed in the OFW boot-device environment variable. 1491 149220120712: 1493 The OpenSSL has been upgraded to 1.0.1c. Any binaries requiring 1494 libcrypto.so.6 or libssl.so.6 must be recompiled. Also, there are 1495 configuration changes. Make sure to merge /etc/ssl/openssl.cnf. 1496 149720120712: 1498 The following sysctls and tunables have been renamed for consistency 1499 with other variables: 1500 kern.cam.da.da_send_ordered -> kern.cam.da.send_ordered 1501 kern.cam.ada.ada_send_ordered -> kern.cam.ada.send_ordered 1502 150320120628: 1504 The sort utility has been replaced with BSD sort. For now, GNU sort 1505 is also available as "gnusort" or the default can be set back to 1506 GNU sort by setting WITH_GNU_SORT. In this case, BSD sort will be 1507 installed as "bsdsort". 1508 150920120611: 1510 A new version of ZFS (pool version 5000) has been merged to -HEAD. 1511 Starting with this version the old system of ZFS pool versioning 1512 is superseded by "feature flags". This concept enables forward 1513 compatibility against certain future changes in functionality of ZFS 1514 pools. The first read-only compatible "feature flag" for ZFS pools 1515 is named "com.delphix:async_destroy". For more information 1516 read the new zpool-features(5) manual page. 1517 Please refer to the "ZFS notes" section of this file for information 1518 on upgrading boot ZFS pools. 1519 152020120417: 1521 The malloc(3) implementation embedded in libc now uses sources imported 1522 as contrib/jemalloc. The most disruptive API change is to 1523 /etc/malloc.conf. If your system has an old-style /etc/malloc.conf, 1524 delete it prior to installworld, and optionally re-create it using the 1525 new format after rebooting. See malloc.conf(5) for details 1526 (specifically the TUNING section and the "opt.*" entries in the MALLCTL 1527 NAMESPACE section). 1528 152920120328: 1530 Big-endian MIPS TARGET_ARCH values no longer end in "eb". mips64eb 1531 is now spelled mips64. mipsn32eb is now spelled mipsn32. mipseb is 1532 now spelled mips. This is to aid compatibility with third-party 1533 software that expects this naming scheme in uname(3). Little-endian 1534 settings are unchanged. If you are updating a big-endian mips64 machine 1535 from before this change, you may need to set MACHINE_ARCH=mips64 in 1536 your environment before the new build system will recognize your machine. 1537 153820120306: 1539 Disable by default the option VFS_ALLOW_NONMPSAFE for all supported 1540 platforms. 1541 154220120229: 1543 Now unix domain sockets behave "as expected" on nullfs(5). Previously 1544 nullfs(5) did not pass through all behaviours to the underlying layer, 1545 as a result if we bound to a socket on the lower layer we could connect 1546 only to the lower path; if we bound to the upper layer we could connect 1547 only to the upper path. The new behavior is one can connect to both the 1548 lower and the upper paths regardless what layer path one binds to. 1549 155020120211: 1551 The getifaddrs upgrade path broken with 20111215 has been restored. 1552 If you have upgraded in between 20111215 and 20120209 you need to 1553 recompile libc again with your kernel. You still need to recompile 1554 world to be able to configure CARP but this restriction already 1555 comes from 20111215. 1556 155720120114: 1558 The set_rcvar() function has been removed from /etc/rc.subr. All 1559 base and ports rc.d scripts have been updated, so if you have a 1560 port installed with a script in /usr/local/etc/rc.d you can either 1561 hand-edit the rcvar= line, or reinstall the port. 1562 1563 An easy way to handle the mass-update of /etc/rc.d: 1564 rm /etc/rc.d/* && mergemaster -i 1565 156620120109: 1567 panic(9) now stops other CPUs in the SMP systems, disables interrupts 1568 on the current CPU and prevents other threads from running. 1569 This behavior can be reverted using the kern.stop_scheduler_on_panic 1570 tunable/sysctl. 1571 The new behavior can be incompatible with kern.sync_on_panic. 1572 157320111215: 1574 The carp(4) facility has been changed significantly. Configuration 1575 of the CARP protocol via ifconfig(8) has changed, as well as format 1576 of CARP events submitted to devd(8) has changed. See manual pages 1577 for more information. The arpbalance feature of carp(4) is currently 1578 not supported anymore. 1579 1580 Size of struct in_aliasreq, struct in6_aliasreq has changed. User 1581 utilities using SIOCAIFADDR, SIOCAIFADDR_IN6, e.g. ifconfig(8), 1582 need to be recompiled. 1583 158420111122: 1585 The acpi_wmi(4) status device /dev/wmistat has been renamed to 1586 /dev/wmistat0. 1587 158820111108: 1589 The option VFS_ALLOW_NONMPSAFE option has been added in order to 1590 explicitely support non-MPSAFE filesystems. 1591 It is on by default for all supported platform at this present 1592 time. 1593 159420111101: 1595 The broken amd(4) driver has been replaced with esp(4) in the amd64, 1596 i386 and pc98 GENERIC kernel configuration files. 1597 159820110930: 1599 sysinstall has been removed 1600 160120110923: 1602 The stable/9 branch created in subversion. This corresponds to the 1603 RELENG_9 branch in CVS. 1604 1605COMMON ITEMS: 1606 1607 General Notes 1608 ------------- 1609 Avoid using make -j when upgrading. While generally safe, there are 1610 sometimes problems using -j to upgrade. If your upgrade fails with 1611 -j, please try again without -j. From time to time in the past there 1612 have been problems using -j with buildworld and/or installworld. This 1613 is especially true when upgrading between "distant" versions (eg one 1614 that cross a major release boundary or several minor releases, or when 1615 several months have passed on the -current branch). 1616 1617 Sometimes, obscure build problems are the result of environment 1618 poisoning. This can happen because the make utility reads its 1619 environment when searching for values for global variables. To run 1620 your build attempts in an "environmental clean room", prefix all make 1621 commands with 'env -i '. See the env(1) manual page for more details. 1622 1623 When upgrading from one major version to another it is generally best 1624 to upgrade to the latest code in the currently installed branch first, 1625 then do an upgrade to the new branch. This is the best-tested upgrade 1626 path, and has the highest probability of being successful. Please try 1627 this approach before reporting problems with a major version upgrade. 1628 1629 When upgrading a live system, having a root shell around before 1630 installing anything can help undo problems. Not having a root shell 1631 around can lead to problems if pam has changed too much from your 1632 starting point to allow continued authentication after the upgrade. 1633 1634 This file should be read as a log of events. When a later event changes 1635 information of a prior event, the prior event should not be deleted. 1636 Instead, a pointer to the entry with the new information should be 1637 placed in the old entry. Readers of this file should also sanity check 1638 older entries before relying on them blindly. Authors of new entries 1639 should write them with this in mind. 1640 1641 ZFS notes 1642 --------- 1643 When upgrading the boot ZFS pool to a new version, always follow 1644 these two steps: 1645 1646 1.) recompile and reinstall the ZFS boot loader and boot block 1647 (this is part of "make buildworld" and "make installworld") 1648 1649 2.) update the ZFS boot block on your boot drive 1650 1651 The following example updates the ZFS boot block on the first 1652 partition (freebsd-boot) of a GPT partitioned drive ada0: 1653 "gpart bootcode -p /boot/gptzfsboot -i 1 ada0" 1654 1655 Non-boot pools do not need these updates. 1656 1657 To build a kernel 1658 ----------------- 1659 If you are updating from a prior version of FreeBSD (even one just 1660 a few days old), you should follow this procedure. It is the most 1661 failsafe as it uses a /usr/obj tree with a fresh mini-buildworld, 1662 1663 make kernel-toolchain 1664 make -DALWAYS_CHECK_MAKE buildkernel KERNCONF=YOUR_KERNEL_HERE 1665 make -DALWAYS_CHECK_MAKE installkernel KERNCONF=YOUR_KERNEL_HERE 1666 1667 To test a kernel once 1668 --------------------- 1669 If you just want to boot a kernel once (because you are not sure 1670 if it works, or if you want to boot a known bad kernel to provide 1671 debugging information) run 1672 make installkernel KERNCONF=YOUR_KERNEL_HERE KODIR=/boot/testkernel 1673 nextboot -k testkernel 1674 1675 To just build a kernel when you know that it won't mess you up 1676 -------------------------------------------------------------- 1677 This assumes you are already running a CURRENT system. Replace 1678 ${arch} with the architecture of your machine (e.g. "i386", 1679 "arm", "amd64", "ia64", "pc98", "sparc64", "powerpc", "mips", etc). 1680 1681 cd src/sys/${arch}/conf 1682 config KERNEL_NAME_HERE 1683 cd ../compile/KERNEL_NAME_HERE 1684 make depend 1685 make 1686 make install 1687 1688 If this fails, go to the "To build a kernel" section. 1689 1690 To rebuild everything and install it on the current system. 1691 ----------------------------------------------------------- 1692 # Note: sometimes if you are running current you gotta do more than 1693 # is listed here if you are upgrading from a really old current. 1694 1695 <make sure you have good level 0 dumps> 1696 make buildworld 1697 make kernel KERNCONF=YOUR_KERNEL_HERE 1698 [1] 1699 <reboot in single user> [3] 1700 mergemaster -Fp [5] 1701 make installworld 1702 mergemaster -Fi [4] 1703 make delete-old [6] 1704 <reboot> 1705 1706 To cross-install current onto a separate partition 1707 -------------------------------------------------- 1708 # In this approach we use a separate partition to hold 1709 # current's root, 'usr', and 'var' directories. A partition 1710 # holding "/", "/usr" and "/var" should be about 2GB in 1711 # size. 1712 1713 <make sure you have good level 0 dumps> 1714 <boot into -stable> 1715 make buildworld 1716 make buildkernel KERNCONF=YOUR_KERNEL_HERE 1717 <maybe newfs current's root partition> 1718 <mount current's root partition on directory ${CURRENT_ROOT}> 1719 make installworld DESTDIR=${CURRENT_ROOT} -DDB_FROM_SRC 1720 make distribution DESTDIR=${CURRENT_ROOT} # if newfs'd 1721 make installkernel KERNCONF=YOUR_KERNEL_HERE DESTDIR=${CURRENT_ROOT} 1722 cp /etc/fstab ${CURRENT_ROOT}/etc/fstab # if newfs'd 1723 <edit ${CURRENT_ROOT}/etc/fstab to mount "/" from the correct partition> 1724 <reboot into current> 1725 <do a "native" rebuild/install as described in the previous section> 1726 <maybe install compatibility libraries from ports/misc/compat*> 1727 <reboot> 1728 1729 1730 To upgrade in-place from stable to current 1731 ---------------------------------------------- 1732 <make sure you have good level 0 dumps> 1733 make buildworld [9] 1734 make kernel KERNCONF=YOUR_KERNEL_HERE [8] 1735 [1] 1736 <reboot in single user> [3] 1737 mergemaster -Fp [5] 1738 make installworld 1739 mergemaster -Fi [4] 1740 make delete-old [6] 1741 <reboot> 1742 1743 Make sure that you've read the UPDATING file to understand the 1744 tweaks to various things you need. At this point in the life 1745 cycle of current, things change often and you are on your own 1746 to cope. The defaults can also change, so please read ALL of 1747 the UPDATING entries. 1748 1749 Also, if you are tracking -current, you must be subscribed to 1750 freebsd-current@freebsd.org. Make sure that before you update 1751 your sources that you have read and understood all the recent 1752 messages there. If in doubt, please track -stable which has 1753 much fewer pitfalls. 1754 1755 [1] If you have third party modules, such as vmware, you 1756 should disable them at this point so they don't crash your 1757 system on reboot. 1758 1759 [3] From the bootblocks, boot -s, and then do 1760 fsck -p 1761 mount -u / 1762 mount -a 1763 cd src 1764 adjkerntz -i # if CMOS is wall time 1765 Also, when doing a major release upgrade, it is required that 1766 you boot into single user mode to do the installworld. 1767 1768 [4] Note: This step is non-optional. Failure to do this step 1769 can result in a significant reduction in the functionality of the 1770 system. Attempting to do it by hand is not recommended and those 1771 that pursue this avenue should read this file carefully, as well 1772 as the archives of freebsd-current and freebsd-hackers mailing lists 1773 for potential gotchas. The -U option is also useful to consider. 1774 See mergemaster(8) for more information. 1775 1776 [5] Usually this step is a noop. However, from time to time 1777 you may need to do this if you get unknown user in the following 1778 step. It never hurts to do it all the time. You may need to 1779 install a new mergemaster (cd src/usr.sbin/mergemaster && make 1780 install) after the buildworld before this step if you last updated 1781 from current before 20130425 or from -stable before 20130430. 1782 1783 [6] This only deletes old files and directories. Old libraries 1784 can be deleted by "make delete-old-libs", but you have to make 1785 sure that no program is using those libraries anymore. 1786 1787 [8] In order to have a kernel that can run the 4.x binaries needed to 1788 do an installworld, you must include the COMPAT_FREEBSD4 option in 1789 your kernel. Failure to do so may leave you with a system that is 1790 hard to boot to recover. A similar kernel option COMPAT_FREEBSD5 is 1791 required to run the 5.x binaries on more recent kernels. And so on 1792 for COMPAT_FREEBSD6 and COMPAT_FREEBSD7. 1793 1794 Make sure that you merge any new devices from GENERIC since the 1795 last time you updated your kernel config file. 1796 1797 [9] When checking out sources, you must include the -P flag to have 1798 cvs prune empty directories. 1799 1800 If CPUTYPE is defined in your /etc/make.conf, make sure to use the 1801 "?=" instead of the "=" assignment operator, so that buildworld can 1802 override the CPUTYPE if it needs to. 1803 1804 MAKEOBJDIRPREFIX must be defined in an environment variable, and 1805 not on the command line, or in /etc/make.conf. buildworld will 1806 warn if it is improperly defined. 1807FORMAT: 1808 1809This file contains a list, in reverse chronological order, of major 1810breakages in tracking -current. It is not guaranteed to be a complete 1811list of such breakages, and only contains entries since September 23, 2011. 1812If you need to see UPDATING entries from before that date, you will need 1813to fetch an UPDATING file from an older FreeBSD release. 1814 1815Copyright information: 1816 1817Copyright 1998-2009 M.
