UPDATING revision 346755
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 1920190426: 20 CARP now sets DSCP value CS7(Network Traffic) in the flowlabel field 21 of packets by default instead of only setting TOS_LOWDELAY in IPv4, 22 which was deprecated in 1998. Original behavior can be restored by 23 setting sysctl net.inet.carp.dscp=4. 24 2520190416: 26 Clang, llvm, lld, lldb, compiler-rt and libc++ have been upgraded to 27 8.0.0. Please see the 20141231 entry below for information about 28 prerequisites and upgrading, if you are not already using clang 3.5.0 29 or higher. 30 3120190226: 32 geom_uzip(4) depends on the new module xz. If geom_uzip is statically 33 compiled into your custom kernel, add 'device xz' statement to the 34 kernel config. 35 3620190220: 37 Co-existance for Forth and Lua interpreters in bootloaders has now been 38 merged to ease testing of lualoader. LOADER_DEFAULT_INTERP, documented 39 in build(7), may be used to control which interpreter flavor is used in 40 the default loader to be installed. For systems where Lua and Forth 41 coexist, this switch can also be made on a running system by creating a 42 link from /boot/loader{,.efi} to /boot/loader_${flavor}{,.efi} rather 43 than requiring a rebuild. 44 45 The default flavor in this branch will remain Forth. As indicated in 46 the 20190216 UPDATING entry, booting is a complex environment; it would 47 be prudent to assume that lualoader may not work for your setup and make 48 provisions for backup boot methods. 49 5020190220: 51 zfsloader's functionality has now been folded into loader. 52 zfsloader is no longer necesasary once you've updated your 53 boot blocks. For a transition period, we will install a 54 hardlink for zfsloader to loader to allow a smooth transition 55 until the boot blocks can be updated (hard link because old 56 zfs boot blocks don't understand symlinks). 57 5820190216: 59 Lualoader has been merged to facilitate testing on this branch. It's 60 purely opt-in for now by building WITH_LOADER_LUA and WITHOUT_FORTH in 61 /etc/src.conf, but co-existance will come shortly. Booting is a complex 62 environment and test coverage for Lua-enabled loaders has been thin, so 63 it would be prudent to assume it might not work and make provisions for 64 backup boot methods. 65 6620190216: 67 Clang, llvm, lld, lldb, compiler-rt and libc++ have been upgraded to 68 7.0.1. Please see the 20141231 entry below for information about 69 prerequisites and upgrading, if you are not already using clang 3.5.0 70 or higher. 71 7220181228: 73 r342562 modifies the NFSv4 server so that it obeys vfs.nfsd.nfs_privport 74 in the same as it is applied to NFSv2 and 3. This implies that NFSv4 75 servers that have vfs.nfsd.nfs_privport set will only allow mounts 76 from clients using a reserved port#. Since both the FreeBSD and Linux 77 NFSv4 clients use reserved port#s by default, this should not affect 78 most NFSv4 mounts. 79 8020181107: 81 The '%I' format in the kern.corefile sysctl limits the number of 82 core files that a process can generate to the number stored in the 83 debug.ncores sysctl. The '%I' format is replaced by the single digit 84 index. Previously, if all indexes were taken the kernel would overwrite 85 only a core file with the highest index in a filename. 86 Currently the system will create a new core file if there is a free 87 index or if all slots are taken it will overwrite the oldest one. 88 8920180818: 90 WITH_OFED option now only enables the build for the OFED libraries 91 and some fundamental client utilities. OpenSM and rest of the 92 debugging tools are enabled by WITH_OFED_EXTRA build switch. 93 WITH_OFED is turned on by default on amd64. 94 9520180714: 96 Clang, llvm, lld, lldb, compiler-rt and libc++ have been upgraded to 97 6.0.1. Please see the 20141231 entry below for information about 98 prerequisites and upgrading, if you are not already using clang 3.5.0 99 or higher. 100 10120180601: 102 The releng/11.2 branch has been created from stable/11@r334458. 103 10420180504: 105 The tz database (tzdb) has been updated to 2018e. This version more 106 correctly models time stamps in time zones with negative DST such as 107 Europe/Dublin (from 1971 on), Europe/Prague (1946/7), and 108 Africa/Windhoek (1994/2017). This does not affect the UT offsets, only 109 time zone abbreviations and the tm_isdst flag. 110 11120180409: 112 The use of RSS hash from the network card aka flowid has been 113 disabled by default for lagg(4) as it's currently incompatible with 114 the lacp and loadbalance protocols. 115 116 This can be re-enabled by setting the following in loader.conf: 117 net.link.lagg.default_use_flowid="1" 118 11920180331: 120 Clang, llvm, lld, lldb, compiler-rt and libc++ have been upgraded to 121 6.0.0. Please see the 20141231 entry below for information about 122 prerequisites and upgrading, if you are not already using clang 3.5.0 123 or higher. 124 12520180211: 126 The LOADER_FIREWIRE_SUPPORT build variable as been renamed to 127 WITH/OUT_LOADER_FIREWIRE. LOADER_{NO_,}GELI_SUPPORT has been renamed 128 to WITH/OUT_LOADER_GELI. 129 13020180210: 131 The geli password typed at boot is now hidden. To restore the previous 132 behavior, see geli(8) for configuration options. 133 134 The SW_WATCHDOG option is no longer necessary to enable the 135 hardclock-based software watchdog if no hardware watchdog is 136 configured. As before, SW_WATCHDOG will cause the software 137 watchdog to be enabled even if a hardware watchdog is configured. 138 13920180108: 140 lint(1) binaries and library are no longer built by default. To 141 enable building them, define WITH_LINT in src.conf. If you are using 142 a FreeBSD 12 or later system to build 11-stable, you may need to 143 install a lint(1) binary to use WITH_LINT. 144 14520171003: 146 When building multiple kernels using KERNCONF, non-existent KERNCONF 147 files will produce an error and buildkernel will fail. Previously 148 missing KERNCONF files silently failed giving no indication as to 149 why, only to subsequently discover during installkernel that the 150 desired kernel was never built in the first place. 151 15220170926: 153 Clang, llvm, lldb, compiler-rt and libc++ have been upgraded to 5.0.0. 154 Please see the 20141231 entry below for information about prerequisites 155 and upgrading, if you are not already using clang 3.5.0 or higher. 156 15720170822: 158 Since the switch to GPT disk labels, fsck for UFS/FFS has been 159 unable to automatically find alternate superblocks. As of r322806, 160 the information needed to find alternate superblocks has been 161 moved to the end of the area reserved for the boot block. 162 Filesystems created with a newfs of this vintage or later 163 will create the recovery information. If you have a filesystem 164 created prior to this change and wish to have a recovery block 165 created for your filesystem, you can do so by running fsck in 166 forground mode (i.e., do not use the -p or -y options). As it 167 starts, fsck will ask ``SAVE DATA TO FIND ALTERNATE SUPERBLOCKS'' 168 to which you should answer yes. 169 17020170629: 171 The releng/11.1 branch has been created from stable/11@r320475. 172 17320170518: 174 arm64 builds now use the base system LLD 4.0.0 linker by default, 175 instead of requiring that the aarch64-binutils port or package be 176 installed. To continue using aarch64-binutils, set 177 CROSS_BINUTILS_PREFIX=/usr/local/aarch64-freebsd/bin . 178 17920170529: 180 The ctl.ko module no longer implements the iSCSI target frontend: 181 cfiscsi.ko does instead. 182 183 If building cfiscsi.ko as a kernel module, the module can be loaded 184 via one of the following methods: 185 - `cfiscsi_load="YES"` in loader.conf(5). 186 - Add `cfiscsi` to `$kld_list` in rc.conf(5). 187 - ctladm(8)/ctld(8), when compiled with iSCSI support 188 (`WITH_ISCSI=yes` in src.conf(5)) 189 190 Please see cfiscsi(4) for more details. 191 19220170511: 193 The mmcsd.ko module now additionally depends on geom_flashmap.ko. 194 Also, mmc.ko and mmcsd.ko need to be a matching pair built from the 195 same source (previously, the dependency of mmcsd.ko on mmc.ko was 196 missing, but mmcsd.ko now will refuse to load if it is incompatible 197 with mmc.ko). 198 19920170414: 200 Binds and sends to the loopback addresses, IPv6 and IPv4, will now 201 use any explicitly assigned loopback address available in the jail 202 instead of using the first assigned address of the jail. 203 20420170413: 205 As of r316810 for ipfilter, keep frags is no longer assumed when 206 keep state is specified in a rule. r316810 aligns ipfilter with 207 documentation in man pages separating keep frags from keep state. 208 This allows keep state to specified without forcing keep frags 209 and allows keep frags to be specified independently of keep state. 210 To maintain previous behaviour, also specify keep frags with 211 keep state (as documented in ipf.conf.5). 212 21320170402: 214 Clang, llvm, lldb, compiler-rt and libc++ have been upgraded to 4.0.0. 215 Please see the 20141231 entry below for information about prerequisites 216 and upgrading, if you are not already using clang 3.5.0 or higher. 217 21820170323: 219 The code that provides support for ZFS .zfs/ directory functionality 220 has been reimplemented. It's not possible now to create a snapshot 221 by mkdir under .zfs/snapshot/. That should be the only user visible 222 change. 223 22420170319: 225 Many changes in the IPsec code have been merged from the FreeBSD-CURRENT 226 branch. The IPSEC_FILTERTUNNEL kernel option is removed in favour of 227 corresponding sysctl. The IPSEC_NAT_T kernel option is also removed, 228 and now NAT-T is supported by default. Security associations now use 229 the single namespace for SPI allocation, so if you use several manually 230 configured security associations with the same SPI, this configuration 231 needs modification. 232 23320161217: 234 Clang, llvm, lldb, compiler-rt and libc++ have been upgraded to 3.9.1. 235 Please see the 20141231 entry below for information about prerequisites 236 and upgrading, if you are not already using clang 3.5.0 or higher. 237 23820161124: 239 Clang, llvm, lldb, compiler-rt and libc++ have been upgraded to 3.9.0. 240 Please see the 20141231 entry below for information about prerequisites 241 and upgrading, if you are not already using clang 3.5.0 or higher. 242 24320161119: 244 The layout of the pmap structure has changed for powerpc to put the pmap 245 statistics at the front for all CPU variations. libkvm(3) and all tools 246 that link against it need to be recompiled. 247 24820161030: 249 isl(4) and cyapa(4) drivers now require a new driver, 250 chromebook_platform(4), to work properly on Chromebook-class hardware. 251 On other types of hardware the drivers may need to be configured using 252 device hints. Please see the corresponding manual pages for details. 253 25420161210: 255 Relocatable object files with the extension of .So have been renamed 256 to use an extension of .pico instead. The purpose of this change is 257 to avoid a name clash with shared libraries on case-insensitive file 258 systems. On those file systems, foo.So is the same file as foo.so. 259 26020160811: 261 The releng/11.0 branch has been created from stable/11@r303970. 262 26320160708: 264 The stable/11 branch has been created from head@r302406. 265 26620160622: 267 The libc stub for the pipe(2) system call has been replaced with 268 a wrapper that calls the pipe2(2) system call and the pipe(2) 269 system call is now only implemented by the kernels that include 270 "options COMPAT_FREEBSD10" in their config file (this is the 271 default). Users should ensure that this option is enabled in 272 their kernel or upgrade userspace to r302092 before upgrading their 273 kernel. 274 27520160527: 276 CAM will now strip leading spaces from SCSI disks' serial numbers. 277 This will effect users who create UFS filesystems on SCSI disks using 278 those disk's diskid device nodes. For example, if /etc/fstab 279 previously contained a line like 280 "/dev/diskid/DISK-%20%20%20%20%20%20%20ABCDEFG0123456", you should 281 change it to "/dev/diskid/DISK-ABCDEFG0123456". Users of geom 282 transforms like gmirror may also be affected. ZFS users should 283 generally be fine. 284 28520160523: 286 The bitstring(3) API has been updated with new functionality and 287 improved performance. But it is binary-incompatible with the old API. 288 Objects built with the new headers may not be linked against objects 289 built with the old headers. 290 29120160520: 292 The brk and sbrk functions have been removed from libc on arm64. 293 Binutils from ports has been updated to not link to these 294 functions and should be updated to the latest version before 295 installing a new libc. 296 29720160517: 298 The armv6 port now defaults to hard float ABI. Limited support 299 for running both hardfloat and soft float on the same system 300 is available using the libraries installed with -DWITH_LIBSOFT. 301 This has only been tested as an upgrade path for installworld 302 and packages may fail or need manual intervention to run. New 303 packages will be needed. 304 305 To update an existing self-hosted armv6hf system, you must add 306 TARGET_ARCH=armv6 on the make command line for both the build 307 and the install steps. 308 30920160510: 310 Kernel modules compiled outside of a kernel build now default to 311 installing to /boot/modules instead of /boot/kernel. Many kernel 312 modules built this way (such as those in ports) already overrode 313 KMODDIR explicitly to install into /boot/modules. However, 314 manually building and installing a module from /sys/modules will 315 now install to /boot/modules instead of /boot/kernel. 316 31720160414: 318 The CAM I/O scheduler has been committed to the kernel. There should be 319 no user visible impact. This does enable NCQ Trim on ada SSDs. While the 320 list of known rogues that claim support for this but actually corrupt 321 data is believed to be complete, be on the lookout for data 322 corruption. The known rogue list is believed to be complete: 323 324 o Crucial MX100, M550 drives with MU01 firmware. 325 o Micron M510 and M550 drives with MU01 firmware. 326 o Micron M500 prior to MU07 firmware 327 o Samsung 830, 840, and 850 all firmwares 328 o FCCT M500 all firmwares 329 330 Crucial has firmware http://www.crucial.com/usa/en/support-ssd-firmware 331 with working NCQ TRIM. For Micron branded drives, see your sales rep for 332 updated firmware. Black listed drives will work correctly because these 333 drives work correctly so long as no NCQ TRIMs are sent to them. Given 334 this list is the same as found in Linux, it's believed there are no 335 other rogues in the market place. All other models from the above 336 vendors work. 337 338 To be safe, if you are at all concerned, you can quirk each of your 339 drives to prevent NCQ from being sent by setting: 340 kern.cam.ada.X.quirks="0x2" 341 in loader.conf. If the drive requires the 4k sector quirk, set the 342 quirks entry to 0x3. 343 34420160330: 345 The FAST_DEPEND build option has been removed and its functionality is 346 now the one true way. The old mkdep(1) style of 'make depend' has 347 been removed. See 20160311 for further details. 348 34920160317: 350 Resource range types have grown from unsigned long to uintmax_t. All 351 drivers, and anything using libdevinfo, need to be recompiled. 352 35320160311: 354 WITH_FAST_DEPEND is now enabled by default for in-tree and out-of-tree 355 builds. It no longer runs mkdep(1) during 'make depend', and the 356 'make depend' stage can safely be skipped now as it is auto ran 357 when building 'make all' and will generate all SRCS and DPSRCS before 358 building anything else. Dependencies are gathered at compile time with 359 -MF flags kept in separate .depend files per object file. Users should 360 run 'make cleandepend' once if using -DNO_CLEAN to clean out older 361 stale .depend files. 362 36320160306: 364 On amd64, clang 3.8.0 can now insert sections of type AMD64_UNWIND into 365 kernel modules. Therefore, if you load any kernel modules at boot time, 366 please install the boot loaders after you install the kernel, but before 367 rebooting, e.g.: 368 369 make buildworld 370 make kernel KERNCONF=YOUR_KERNEL_HERE 371 make -C sys/boot install 372 <reboot in single user> 373 374 Then follow the usual steps, described in the General Notes section, 375 below. 376 37720160305: 378 Clang, llvm, lldb and compiler-rt have been upgraded to 3.8.0. Please 379 see the 20141231 entry below for information about prerequisites and 380 upgrading, if you are not already using clang 3.5.0 or higher. 381 38220160301: 383 The AIO subsystem is now a standard part of the kernel. The 384 VFS_AIO kernel option and aio.ko kernel module have been removed. 385 Due to stability concerns, asynchronous I/O requests are only 386 permitted on sockets and raw disks by default. To enable 387 asynchronous I/O requests on all file types, set the 388 vfs.aio.enable_unsafe sysctl to a non-zero value. 389 39020160226: 391 The ELF object manipulation tool objcopy is now provided by the 392 ELF Tool Chain project rather than by GNU binutils. It should be a 393 drop-in replacement, with the addition of arm64 support. The 394 (temporary) src.conf knob WITHOUT_ELFCOPY_AS_OBJCOPY knob may be set 395 to obtain the GNU version if necessary. 396 39720160129: 398 Building ZFS pools on top of zvols is prohibited by default. That 399 feature has never worked safely; it's always been prone to deadlocks. 400 Using a zvol as the backing store for a VM guest's virtual disk will 401 still work, even if the guest is using ZFS. Legacy behavior can be 402 restored by setting vfs.zfs.vol.recursive=1. 403 40420160119: 405 The NONE and HPN patches has been removed from OpenSSH. They are 406 still available in the security/openssh-portable port. 407 40820160113: 409 With the addition of ypldap(8), a new _ypldap user is now required 410 during installworld. "mergemaster -p" can be used to add the user 411 prior to installworld, as documented in the handbook. 412 41320151216: 414 The tftp loader (pxeboot) now uses the option root-path directive. As a 415 consequence it no longer looks for a pxeboot.4th file on the tftp 416 server. Instead it uses the regular /boot infrastructure as with the 417 other loaders. 418 41920151211: 420 The code to start recording plug and play data into the modules has 421 been committed. While the old tools will properly build a new kernel, 422 a number of warnings about "unknown metadata record 4" will be produced 423 for an older kldxref. To avoid such warnings, make sure to rebuild 424 the kernel toolchain (or world). Make sure that you have r292078 or 425 later when trying to build 292077 or later before rebuilding. 426 42720151207: 428 Debug data files are now built by default with 'make buildworld' and 429 installed with 'make installworld'. This facilitates debugging but 430 requires more disk space both during the build and for the installed 431 world. Debug files may be disabled by setting WITHOUT_DEBUG_FILES=yes 432 in src.conf(5). 433 43420151130: 435 r291527 changed the internal interface between the nfsd.ko and 436 nfscommon.ko modules. As such, they must both be upgraded to-gether. 437 __FreeBSD_version has been bumped because of this. 438 43920151108: 440 Add support for unicode collation strings leads to a change of 441 order of files listed by ls(1) for example. To get back to the old 442 behaviour, set LC_COLLATE environment variable to "C". 443 444 Databases administrators will need to reindex their databases given 445 collation results will be different. 446 447 Due to a bug in install(1) it is recommended to remove the ancient 448 locales before running make installworld. 449 450 rm -rf /usr/share/locale/* 451 45220151030: 453 The OpenSSL has been upgraded to 1.0.2d. Any binaries requiring 454 libcrypto.so.7 or libssl.so.7 must be recompiled. 455 45620151020: 457 Qlogic 24xx/25xx firmware images were updated from 5.5.0 to 7.3.0. 458 Kernel modules isp_2400_multi and isp_2500_multi were removed and 459 should be replaced with isp_2400 and isp_2500 modules respectively. 460 46120151017: 462 The build previously allowed using 'make -n' to not recurse into 463 sub-directories while showing what commands would be executed, and 464 'make -n -n' to recursively show commands. Now 'make -n' will recurse 465 and 'make -N' will not. 466 46720151012: 468 If you specify SENDMAIL_MC or SENDMAIL_CF in make.conf, mergemaster 469 and etcupdate will now use this file. A custom sendmail.cf is now 470 updated via this mechanism rather than via installworld. If you had 471 excluded sendmail.cf in mergemaster.rc or etcupdate.conf, you may 472 want to remove the exclusion or change it to "always install". 473 /etc/mail/sendmail.cf is now managed the same way regardless of 474 whether SENDMAIL_MC/SENDMAIL_CF is used. If you are not using 475 SENDMAIL_MC/SENDMAIL_CF there should be no change in behavior. 476 47720151011: 478 Compatibility shims for legacy ATA device names have been removed. 479 It includes ATA_STATIC_ID kernel option, kern.cam.ada.legacy_aliases 480 and kern.geom.raid.legacy_aliases loader tunables, kern.devalias.* 481 environment variables, /dev/ad* and /dev/ar* symbolic links. 482 48320151006: 484 Clang, llvm, lldb, compiler-rt and libc++ have been upgraded to 3.7.0. 485 Please see the 20141231 entry below for information about prerequisites 486 and upgrading, if you are not already using clang 3.5.0 or higher. 487 48820150924: 489 Kernel debug files have been moved to /usr/lib/debug/boot/kernel/, 490 and renamed from .symbols to .debug. This reduces the size requirements 491 on the boot partition or file system and provides consistency with 492 userland debug files. 493 494 When using the supported kernel installation method the 495 /usr/lib/debug/boot/kernel directory will be renamed (to kernel.old) 496 as is done with /boot/kernel. 497 498 Developers wishing to maintain the historical behavior of installing 499 debug files in /boot/kernel/ can set KERN_DEBUGDIR="" in src.conf(5). 500 50120150827: 502 The wireless drivers had undergone changes that remove the 'parent 503 interface' from the ifconfig -l output. The rc.d network scripts 504 used to check presence of a parent interface in the list, so old 505 scripts would fail to start wireless networking. Thus, etcupdate(3) 506 or mergemaster(8) run is required after kernel update, to update your 507 rc.d scripts in /etc. 508 50920150827: 510 pf no longer supports 'scrub fragment crop' or 'scrub fragment drop-ovl' 511 These configurations are now automatically interpreted as 512 'scrub fragment reassemble'. 513 51420150817: 515 Kernel-loadable modules for the random(4) device are back. To use 516 them, the kernel must have 517 518 device random 519 options RANDOM_LOADABLE 520 521 kldload(8) can then be used to load random_fortuna.ko 522 or random_yarrow.ko. Please note that due to the indirect 523 function calls that the loadable modules need to provide, 524 the build-in variants will be slightly more efficient. 525 526 The random(4) kernel option RANDOM_DUMMY has been retired due to 527 unpopularity. It was not all that useful anyway. 528 52920150813: 530 The WITHOUT_ELFTOOLCHAIN_TOOLS src.conf(5) knob has been retired. 531 Control over building the ELF Tool Chain tools is now provided by 532 the WITHOUT_TOOLCHAIN knob. 533 53420150810: 535 The polarity of Pulse Per Second (PPS) capture events with the 536 uart(4) driver has been corrected. Prior to this change the PPS 537 "assert" event corresponded to the trailing edge of a positive PPS 538 pulse and the "clear" event was the leading edge of the next pulse. 539 540 As the width of a PPS pulse in a typical GPS receiver is on the 541 order of 1 millisecond, most users will not notice any significant 542 difference with this change. 543 544 Anyone who has compensated for the historical polarity reversal by 545 configuring a negative offset equal to the pulse width will need to 546 remove that workaround. 547 54820150809: 549 The default group assigned to /dev/dri entries has been changed 550 from 'wheel' to 'video' with the id of '44'. If you want to have 551 access to the dri devices please add yourself to the video group 552 with: 553 554 # pw groupmod video -m $USER 555 55620150806: 557 The menu.rc and loader.rc files will now be replaced during 558 upgrades. Please migrate local changes to menu.rc.local and 559 loader.rc.local instead. 560 56120150805: 562 GNU Binutils versions of addr2line, c++filt, nm, readelf, size, 563 strings and strip have been removed. The src.conf(5) knob 564 WITHOUT_ELFTOOLCHAIN_TOOLS no longer provides the binutils tools. 565 56620150728: 567 As ZFS requires more kernel stack pages than is the default on some 568 architectures e.g. i386, it now warns if KSTACK_PAGES is less than 569 ZFS_MIN_KSTACK_PAGES (which is 4 at the time of writing). 570 571 Please consider using 'options KSTACK_PAGES=X' where X is greater 572 than or equal to ZFS_MIN_KSTACK_PAGES i.e. 4 in such configurations. 573 57420150706: 575 sendmail has been updated to 8.15.2. Starting with FreeBSD 11.0 576 and sendmail 8.15, sendmail uses uncompressed IPv6 addresses by 577 default, i.e., they will not contain "::". For example, instead 578 of ::1, it will be 0:0:0:0:0:0:0:1. This permits a zero subnet 579 to have a more specific match, such as different map entries for 580 IPv6:0:0 vs IPv6:0. This change requires that configuration 581 data (including maps, files, classes, custom ruleset, etc.) must 582 use the same format, so make certain such configuration data is 583 upgrading. As a very simple check search for patterns like 584 'IPv6:[0-9a-fA-F:]*::' and 'IPv6::'. To return to the old 585 behavior, set the m4 option confUSE_COMPRESSED_IPV6_ADDRESSES or 586 the cf option UseCompressedIPv6Addresses. 587 58820150630: 589 The default kernel entropy-processing algorithm is now 590 Fortuna, replacing Yarrow. 591 592 Assuming you have 'device random' in your kernel config 593 file, the configurations allow a kernel option to override 594 this default. You may choose *ONE* of: 595 596 options RANDOM_YARROW # Legacy /dev/random algorithm. 597 options RANDOM_DUMMY # Blocking-only driver. 598 599 If you have neither, you get Fortuna. For most people, 600 read no further, Fortuna will give a /dev/random that works 601 like it always used to, and the difference will be irrelevant. 602 603 If you remove 'device random', you get *NO* kernel-processed 604 entropy at all. This may be acceptable to folks building 605 embedded systems, but has complications. Carry on reading, 606 and it is assumed you know what you need. 607 608 *PLEASE* read random(4) and random(9) if you are in the 609 habit of tweaking kernel configs, and/or if you are a member 610 of the embedded community, wanting specific and not-usual 611 behaviour from your security subsystems. 612 613 NOTE!! If you use RANDOM_DUMMY and/or have no 'device 614 random', you will NOT have a functioning /dev/random, and 615 many cryptographic features will not work, including SSH. 616 You may also find strange behaviour from the random(3) set 617 of library functions, in particular sranddev(3), srandomdev(3) 618 and arc4random(3). The reason for this is that the KERN_ARND 619 sysctl only returns entropy if it thinks it has some to 620 share, and with RANDOM_DUMMY or no 'device random' this 621 will never happen. 622 62320150623: 624 An additional fix for the issue described in the 20150614 sendmail 625 entry below has been been committed in revision 284717. 626 62720150616: 628 FreeBSD's old make (fmake) has been removed from the system. It is 629 available as the devel/fmake port or via pkg install fmake. 630 63120150615: 632 The fix for the issue described in the 20150614 sendmail entry 633 below has been been committed in revision 284436. The work 634 around described in that entry is no longer needed unless the 635 default setting is overridden by a confDH_PARAMETERS configuration 636 setting of '5' or pointing to a 512 bit DH parameter file. 637 63820150614: 639 ALLOW_DEPRECATED_ATF_TOOLS/ATFFILE support has been removed from 640 atf.test.mk (included from bsd.test.mk). Please upgrade devel/atf 641 and devel/kyua to version 0.20+ and adjust any calling code to work 642 with Kyuafile and kyua. 643 64420150614: 645 The import of openssl to address the FreeBSD-SA-15:10.openssl 646 security advisory includes a change which rejects handshakes 647 with DH parameters below 768 bits. sendmail releases prior 648 to 8.15.2 (not yet released), defaulted to a 512 bit 649 DH parameter setting for client connections. To work around 650 this interoperability, sendmail can be configured to use a 651 2048 bit DH parameter by: 652 653 1. Edit /etc/mail/`hostname`.mc 654 2. If a setting for confDH_PARAMETERS does not exist or 655 exists and is set to a string beginning with '5', 656 replace it with '2'. 657 3. If a setting for confDH_PARAMETERS exists and is set to 658 a file path, create a new file with: 659 openssl dhparam -out /path/to/file 2048 660 4. Rebuild the .cf file: 661 cd /etc/mail/; make; make install 662 5. Restart sendmail: 663 cd /etc/mail/; make restart 664 665 A sendmail patch is coming, at which time this file will be 666 updated. 667 66820150604: 669 Generation of legacy formatted entries have been disabled by default 670 in pwd_mkdb(8), as all base system consumers of the legacy formatted 671 entries were converted to use the new format by default when the new, 672 machine independent format have been added and supported since FreeBSD 673 5.x. 674 675 Please see the pwd_mkdb(8) manual page for further details. 676 67720150525: 678 Clang and llvm have been upgraded to 3.6.1 release. Please see the 679 20141231 entry below for information about prerequisites and upgrading, 680 if you are not already using 3.5.0 or higher. 681 68220150521: 683 TI platform code switched to using vendor DTS files and this update 684 may break existing systems running on Beaglebone, Beaglebone Black, 685 and Pandaboard: 686 687 - dtb files should be regenerated/reinstalled. Filenames are the 688 same but content is different now 689 - GPIO addressing was changed, now each GPIO bank (32 pins per bank) 690 has its own /dev/gpiocX device, e.g. pin 121 on /dev/gpioc0 in old 691 addressing scheme is now pin 25 on /dev/gpioc3. 692 - Pandaboard: /etc/ttys should be updated, serial console device is 693 now /dev/ttyu2, not /dev/ttyu0 694 69520150501: 696 soelim(1) from gnu/usr.bin/groff has been replaced by usr.bin/soelim. 697 If you need the GNU extension from groff soelim(1), install groff 698 from package: pkg install groff, or via ports: textproc/groff. 699 70020150423: 701 chmod, chflags, chown and chgrp now affect symlinks in -R mode as 702 defined in symlink(7); previously symlinks were silently ignored. 703 70420150415: 705 The const qualifier has been removed from iconv(3) to comply with 706 POSIX. The ports tree is aware of this from r384038 onwards. 707 70820150416: 709 Libraries specified by LIBADD in Makefiles must have a corresponding 710 DPADD_<lib> variable to ensure correct dependencies. This is now 711 enforced in src.libnames.mk. 712 71320150324: 714 From legacy ata(4) driver was removed support for SATA controllers 715 supported by more functional drivers ahci(4), siis(4) and mvs(4). 716 Kernel modules ataahci and ataadaptec were removed completely, 717 replaced by ahci and mvs modules respectively. 718 71920150315: 720 Clang, llvm and lldb have been upgraded to 3.6.0 release. Please see 721 the 20141231 entry below for information about prerequisites and 722 upgrading, if you are not already using 3.5.0 or higher. 723 72420150307: 725 The 32-bit PowerPC kernel has been changed to a position-independent 726 executable. This can only be booted with a version of loader(8) 727 newer than January 31, 2015, so make sure to update both world and 728 kernel before rebooting. 729 73020150217: 731 If you are running a -CURRENT kernel since r273872 (Oct 30th, 2014), 732 but before r278950, the RNG was not seeded properly. Immediately 733 upgrade the kernel to r278950 or later and regenerate any keys (e.g. 734 ssh keys or openssl keys) that were generated w/ a kernel from that 735 range. This does not affect programs that directly used /dev/random 736 or /dev/urandom. All userland uses of arc4random(3) are affected. 737 73820150210: 739 The autofs(4) ABI was changed in order to restore binary compatibility 740 with 10.1-RELEASE. The automountd(8) daemon needs to be rebuilt to work 741 with the new kernel. 742 74320150131: 744 The powerpc64 kernel has been changed to a position-independent 745 executable. This can only be booted with a new version of loader(8), 746 so make sure to update both world and kernel before rebooting. 747 74820150118: 749 Clang and llvm have been upgraded to 3.5.1 release. This is a bugfix 750 only release, no new features have been added. Please see the 20141231 751 entry below for information about prerequisites and upgrading, if you 752 are not already using 3.5.0. 753 75420150107: 755 ELF tools addr2line, elfcopy (strip), nm, size, and strings are now 756 taken from the ELF Tool Chain project rather than GNU binutils. They 757 should be drop-in replacements, with the addition of arm64 support. 758 The WITHOUT_ELFTOOLCHAIN_TOOLS= knob may be used to obtain the 759 binutils tools, if necessary. See 20150805 for updated information. 760 76120150105: 762 The default Unbound configuration now enables remote control 763 using a local socket. Users who have already enabled the 764 local_unbound service should regenerate their configuration 765 by running "service local_unbound setup" as root. 766 76720150102: 768 The GNU texinfo and GNU info pages have been removed. 769 To be able to view GNU info pages please install texinfo from ports. 770 77120141231: 772 Clang, llvm and lldb have been upgraded to 3.5.0 release. 773 774 As of this release, a prerequisite for building clang, llvm and lldb is 775 a C++11 capable compiler and C++11 standard library. This means that to 776 be able to successfully build the cross-tools stage of buildworld, with 777 clang as the bootstrap compiler, your system compiler or cross compiler 778 should either be clang 3.3 or later, or gcc 4.8 or later, and your 779 system C++ library should be libc++, or libdstdc++ from gcc 4.8 or 780 later. 781 782 On any standard FreeBSD 10.x or 11.x installation, where clang and 783 libc++ are on by default (that is, on x86 or arm), this should work out 784 of the box. 785 786 On 9.x installations where clang is enabled by default, e.g. on x86 and 787 powerpc, libc++ will not be enabled by default, so libc++ should be 788 built (with clang) and installed first. If both clang and libc++ are 789 missing, build clang first, then use it to build libc++. 790 791 On 8.x and earlier installations, upgrade to 9.x first, and then follow 792 the instructions for 9.x above. 793 794 Sparc64 and mips users are unaffected, as they still use gcc 4.2.1 by 795 default, and do not build clang. 796 797 Many embedded systems are resource constrained, and will not be able to 798 build clang in a reasonable time, or in some cases at all. In those 799 cases, cross building bootable systems on amd64 is a workaround. 800 801 This new version of clang introduces a number of new warnings, of which 802 the following are most likely to appear: 803 804 -Wabsolute-value 805 806 This warns in two cases, for both C and C++: 807 * When the code is trying to take the absolute value of an unsigned 808 quantity, which is effectively a no-op, and almost never what was 809 intended. The code should be fixed, if at all possible. If you are 810 sure that the unsigned quantity can be safely cast to signed, without 811 loss of information or undefined behavior, you can add an explicit 812 cast, or disable the warning. 813 814 * When the code is trying to take an absolute value, but the called 815 abs() variant is for the wrong type, which can lead to truncation. 816 If you want to disable the warning instead of fixing the code, please 817 make sure that truncation will not occur, or it might lead to unwanted 818 side-effects. 819 820 -Wtautological-undefined-compare and 821 -Wundefined-bool-conversion 822 823 These warn when C++ code is trying to compare 'this' against NULL, while 824 'this' should never be NULL in well-defined C++ code. However, there is 825 some legacy (pre C++11) code out there, which actively abuses this 826 feature, which was less strictly defined in previous C++ versions. 827 828 Squid and openjdk do this, for example. The warning can be turned off 829 for C++98 and earlier, but compiling the code in C++11 mode might result 830 in unexpected behavior; for example, the parts of the program that are 831 unreachable could be optimized away. 832 83320141222: 834 The old NFS client and server (kernel options NFSCLIENT, NFSSERVER) 835 kernel sources have been removed. The .h files remain, since some 836 utilities include them. This will need to be fixed later. 837 If "mount -t oldnfs ..." is attempted, it will fail. 838 If the "-o" option on mountd(8), nfsd(8) or nfsstat(1) is used, 839 the utilities will report errors. 840 84120141121: 842 The handling of LOCAL_LIB_DIRS has been altered to skip addition of 843 directories to top level SUBDIR variable when their parent 844 directory is included in LOCAL_DIRS. Users with build systems with 845 such hierarchies and without SUBDIR entries in the parent 846 directory Makefiles should add them or add the directories to 847 LOCAL_DIRS. 848 84920141109: 850 faith(4) and faithd(8) have been removed from the base system. Faith 851 has been obsolete for a very long time. 852 85320141104: 854 vt(4), the new console driver, is enabled by default. It brings 855 support for Unicode and double-width characters, as well as 856 support for UEFI and integration with the KMS kernel video 857 drivers. 858 859 You may need to update your console settings in /etc/rc.conf, 860 most probably the keymap. During boot, /etc/rc.d/syscons will 861 indicate what you need to do. 862 863 vt(4) still has issues and lacks some features compared to 864 syscons(4). See the wiki for up-to-date information: 865 https://wiki.freebsd.org/Newcons 866 867 If you want to keep using syscons(4), you can do so by adding 868 the following line to /boot/loader.conf: 869 kern.vty=sc 870 87120141102: 872 pjdfstest has been integrated into kyua as an opt-in test suite. 873 Please see share/doc/pjdfstest/README for more details on how to 874 execute it. 875 87620141009: 877 gperf has been removed from the base system for architectures 878 that use clang. Ports that require gperf will obtain it from the 879 devel/gperf port. 880 88120140923: 882 pjdfstest has been moved from tools/regression/pjdfstest to 883 contrib/pjdfstest . 884 88520140922: 886 At svn r271982, The default linux compat kernel ABI has been adjusted 887 to 2.6.18 in support of the linux-c6 compat ports infrastructure 888 update. If you wish to continue using the linux-f10 compat ports, 889 add compat.linux.osrelease=2.6.16 to your local sysctl.conf. Users are 890 encouraged to update their linux-compat packages to linux-c6 during 891 their next update cycle. 892 89320140729: 894 The ofwfb driver, used to provide a graphics console on PowerPC when 895 using vt(4), no longer allows mmap() of all physical memory. This 896 will prevent Xorg on PowerPC with some ATI graphics cards from 897 initializing properly unless x11-servers/xorg-server is updated to 898 1.12.4_8 or newer. 899 90020140723: 901 The xdev targets have been converted to using TARGET and 902 TARGET_ARCH instead of XDEV and XDEV_ARCH. 903 90420140719: 905 The default unbound configuration has been modified to address 906 issues with reverse lookups on networks that use private 907 address ranges. If you use the local_unbound service, run 908 "service local_unbound setup" as root to regenerate your 909 configuration, then "service local_unbound reload" to load the 910 new configuration. 911 91220140709: 913 The GNU texinfo and GNU info pages are not built and installed 914 anymore, WITH_INFO knob has been added to allow to built and install 915 them again. 916 UPDATE: see 20150102 entry on texinfo's removal 917 91820140708: 919 The GNU readline library is now an INTERNALLIB - that is, it is 920 statically linked into consumers (GDB and variants) in the base 921 system, and the shared library is no longer installed. The 922 devel/readline port is available for third party software that 923 requires readline. 924 92520140702: 926 The Itanium architecture (ia64) has been removed from the list of 927 known architectures. This is the first step in the removal of the 928 architecture. 929 93020140701: 931 Commit r268115 has added NFSv4.1 server support, merged from 932 projects/nfsv4.1-server. Since this includes changes to the 933 internal interfaces between the NFS related modules, a full 934 build of the kernel and modules will be necessary. 935 __FreeBSD_version has been bumped. 936 93720140629: 938 The WITHOUT_VT_SUPPORT kernel config knob has been renamed 939 WITHOUT_VT. (The other _SUPPORT knobs have a consistent meaning 940 which differs from the behaviour controlled by this knob.) 941 94220140619: 943 Maximal length of the serial number in CTL was increased from 16 to 944 64 chars, that breaks ABI. All CTL-related tools, such as ctladm 945 and ctld, need to be rebuilt to work with a new kernel. 946 94720140606: 948 The libatf-c and libatf-c++ major versions were downgraded to 0 and 949 1 respectively to match the upstream numbers. They were out of 950 sync because, when they were originally added to FreeBSD, the 951 upstream versions were not respected. These libraries are private 952 and not yet built by default, so renumbering them should be a 953 non-issue. However, unclean source trees will yield broken test 954 programs once the operator executes "make delete-old-libs" after a 955 "make installworld". 956 957 Additionally, the atf-sh binary was made private by moving it into 958 /usr/libexec/. Already-built shell test programs will keep the 959 path to the old binary so they will break after "make delete-old" 960 is run. 961 962 If you are using WITH_TESTS=yes (not the default), wipe the object 963 tree and rebuild from scratch to prevent spurious test failures. 964 This is only needed once: the misnumbered libraries and misplaced 965 binaries have been added to OptionalObsoleteFiles.inc so they will 966 be removed during a clean upgrade. 967 96820140512: 969 Clang and llvm have been upgraded to 3.4.1 release. 970 97120140508: 972 We bogusly installed src.opts.mk in /usr/share/mk. This file should 973 be removed to avoid issues in the future (and has been added to 974 ObsoleteFiles.inc). 975 97620140505: 977 /etc/src.conf now affects only builds of the FreeBSD src tree. In the 978 past, it affected all builds that used the bsd.*.mk files. The old 979 behavior was a bug, but people may have relied upon it. To get this 980 behavior back, you can .include /etc/src.conf from /etc/make.conf 981 (which is still global and isn't changed). This also changes the 982 behavior of incremental builds inside the tree of individual 983 directories. Set MAKESYSPATH to ".../share/mk" to do that. 984 Although this has survived make universe and some upgrade scenarios, 985 other upgrade scenarios may have broken. At least one form of 986 temporary breakage was fixed with MAKESYSPATH settings for buildworld 987 as well... In cases where MAKESYSPATH isn't working with this 988 setting, you'll need to set it to the full path to your tree. 989 990 One side effect of all this cleaning up is that bsd.compiler.mk 991 is no longer implicitly included by bsd.own.mk. If you wish to 992 use COMPILER_TYPE, you must now explicitly include bsd.compiler.mk 993 as well. 994 99520140430: 996 The lindev device has been removed since /dev/full has been made a 997 standard device. __FreeBSD_version has been bumped. 998 99920140424: 1000 The knob WITHOUT_VI was added to the base system, which controls 1001 building ex(1), vi(1), etc. Older releases of FreeBSD required ex(1) 1002 in order to reorder files share/termcap and didn't build ex(1) as a 1003 build tool, so building/installing with WITH_VI is highly advised for 1004 build hosts for older releases. 1005 1006 This issue has been fixed in stable/9 and stable/10 in r277022 and 1007 r276991, respectively. 1008 100920140418: 1010 The YES_HESIOD knob has been removed. It has been obsolete for 1011 a decade. Please move to using WITH_HESIOD instead or your builds 1012 will silently lack HESIOD. 1013 101420140405: 1015 The uart(4) driver has been changed with respect to its handling 1016 of the low-level console. Previously the uart(4) driver prevented 1017 any process from changing the baudrate or the CLOCAL and HUPCL 1018 control flags. By removing the restrictions, operators can make 1019 changes to the serial console port without having to reboot. 1020 However, when getty(8) is started on the serial device that is 1021 associated with the low-level console, a misconfigured terminal 1022 line in /etc/ttys will now have a real impact. 1023 Before upgrading the kernel, make sure that /etc/ttys has the 1024 serial console device configured as 3wire without baudrate to 1025 preserve the previous behaviour. E.g: 1026 ttyu0 "/usr/libexec/getty 3wire" vt100 on secure 1027 102820140306: 1029 Support for libwrap (TCP wrappers) in rpcbind was disabled by default 1030 to improve performance. To re-enable it, if needed, run rpcbind 1031 with command line option -W. 1032 103320140226: 1034 Switched back to the GPL dtc compiler due to updates in the upstream 1035 dts files not being supported by the BSDL dtc compiler. You will need 1036 to rebuild your kernel toolchain to pick up the new compiler. Core dumps 1037 may result while building dtb files during a kernel build if you fail 1038 to do so. Set WITHOUT_GPL_DTC if you require the BSDL compiler. 1039 104020140216: 1041 Clang and llvm have been upgraded to 3.4 release. 1042 104320140216: 1044 The nve(4) driver has been removed. Please use the nfe(4) driver 1045 for NVIDIA nForce MCP Ethernet adapters instead. 1046 104720140212: 1048 An ABI incompatibility crept into the libc++ 3.4 import in r261283. 1049 This could cause certain C++ applications using shared libraries built 1050 against the previous version of libc++ to crash. The incompatibility 1051 has now been fixed, but any C++ applications or shared libraries built 1052 between r261283 and r261801 should be recompiled. 1053 105420140204: 1055 OpenSSH will now ignore errors caused by kernel lacking of Capsicum 1056 capability mode support. Please note that enabling the feature in 1057 kernel is still highly recommended. 1058 105920140131: 1060 OpenSSH is now built with sandbox support, and will use sandbox as 1061 the default privilege separation method. This requires Capsicum 1062 capability mode support in kernel. 1063 106420140128: 1065 The libelf and libdwarf libraries have been updated to newer 1066 versions from upstream. Shared library version numbers for 1067 these two libraries were bumped. Any ports or binaries 1068 requiring these two libraries should be recompiled. 1069 __FreeBSD_version is bumped to 1100006. 1070 107120140110: 1072 If a Makefile in a tests/ directory was auto-generating a Kyuafile 1073 instead of providing an explicit one, this would prevent such 1074 Makefile from providing its own Kyuafile in the future during 1075 NO_CLEAN builds. This has been fixed in the Makefiles but manual 1076 intervention is needed to clean an objdir if you use NO_CLEAN: 1077 # find /usr/obj -name Kyuafile | xargs rm -f 1078 107920131213: 1080 The behavior of gss_pseudo_random() for the krb5 mechanism 1081 has changed, for applications requesting a longer random string 1082 than produced by the underlying enctype's pseudo-random() function. 1083 In particular, the random string produced from a session key of 1084 enctype aes256-cts-hmac-sha1-96 or aes256-cts-hmac-sha1-96 will 1085 be different at the 17th octet and later, after this change. 1086 The counter used in the PRF+ construction is now encoded as a 1087 big-endian integer in accordance with RFC 4402. 1088 __FreeBSD_version is bumped to 1100004. 1089 109020131108: 1091 The WITHOUT_ATF build knob has been removed and its functionality 1092 has been subsumed into the more generic WITHOUT_TESTS. If you were 1093 using the former to disable the build of the ATF libraries, you 1094 should change your settings to use the latter. 1095 109620131025: 1097 The default version of mtree is nmtree which is obtained from 1098 NetBSD. The output is generally the same, but may vary 1099 slightly. If you found you need identical output adding 1100 "-F freebsd9" to the command line should do the trick. For the 1101 time being, the old mtree is available as fmtree. 1102 110320131014: 1104 libbsdyml has been renamed to libyaml and moved to /usr/lib/private. 1105 This will break ports-mgmt/pkg. Rebuild the port, or upgrade to pkg 1106 1.1.4_8 and verify bsdyml not linked in, before running "make 1107 delete-old-libs": 1108 # make -C /usr/ports/ports-mgmt/pkg build deinstall install clean 1109 or 1110 # pkg install pkg; ldd /usr/local/sbin/pkg | grep bsdyml 1111 111220131010: 1113 The stable/10 branch has been created in subversion from head 1114 revision r256279. 1115 111620131010: 1117 The rc.d/jail script has been updated to support jail(8) 1118 configuration file. The "jail_<jname>_*" rc.conf(5) variables 1119 for per-jail configuration are automatically converted to 1120 /var/run/jail.<jname>.conf before the jail(8) utility is invoked. 1121 This is transparently backward compatible. See below about some 1122 incompatibilities and rc.conf(5) manual page for more details. 1123 1124 These variables are now deprecated in favor of jail(8) configuration 1125 file. One can use "rc.d/jail config <jname>" command to generate 1126 a jail(8) configuration file in /var/run/jail.<jname>.conf without 1127 running the jail(8) utility. The default pathname of the 1128 configuration file is /etc/jail.conf and can be specified by 1129 using $jail_conf or $jail_<jname>_conf variables. 1130 1131 Please note that jail_devfs_ruleset accepts an integer at 1132 this moment. Please consider to rewrite the ruleset name 1133 with an integer. 1134 113520130930: 1136 BIND has been removed from the base system. If all you need 1137 is a local resolver, simply enable and start the local_unbound 1138 service instead. Otherwise, several versions of BIND are 1139 available in the ports tree. The dns/bind99 port is one example. 1140 1141 With this change, nslookup(1) and dig(1) are no longer in the base 1142 system. Users should instead use host(1) and drill(1) which are 1143 in the base system. Alternatively, nslookup and dig can 1144 be obtained by installing the dns/bind-tools port. 1145 114620130916: 1147 With the addition of unbound(8), a new unbound user is now 1148 required during installworld. "mergemaster -p" can be used to 1149 add the user prior to installworld, as documented in the handbook. 1150 115120130911: 1152 OpenSSH is now built with DNSSEC support, and will by default 1153 silently trust signed SSHFP records. This can be controlled with 1154 the VerifyHostKeyDNS client configuration setting. DNSSEC support 1155 can be disabled entirely with the WITHOUT_LDNS option in src.conf. 1156 115720130906: 1158 The GNU Compiler Collection and C++ standard library (libstdc++) 1159 are no longer built by default on platforms where clang is the system 1160 compiler. You can enable them with the WITH_GCC and WITH_GNUCXX 1161 options in src.conf. 1162 116320130905: 1164 The PROCDESC kernel option is now part of the GENERIC kernel 1165 configuration and is required for the rwhod(8) to work. 1166 If you are using custom kernel configuration, you should include 1167 'options PROCDESC'. 1168 116920130905: 1170 The API and ABI related to the Capsicum framework was modified 1171 in backward incompatible way. The userland libraries and programs 1172 have to be recompiled to work with the new kernel. This includes the 1173 following libraries and programs, but the whole buildworld is 1174 advised: libc, libprocstat, dhclient, tcpdump, hastd, hastctl, 1175 kdump, procstat, rwho, rwhod, uniq. 1176 117720130903: 1178 AES-NI intrinsic support has been added to gcc. The AES-NI module 1179 has been updated to use this support. A new gcc is required to build 1180 the aesni module on both i386 and amd64. 1181 118220130821: 1183 The PADLOCK_RNG and RDRAND_RNG kernel options are now devices. 1184 Thus "device padlock_rng" and "device rdrand_rng" should be 1185 used instead of "options PADLOCK_RNG" & "options RDRAND_RNG". 1186 118720130813: 1188 WITH_ICONV has been split into two feature sets. WITH_ICONV now 1189 enables just the iconv* functionality and is now on by default. 1190 WITH_LIBICONV_COMPAT enables the libiconv api and link time 1191 compatibility. Set WITHOUT_ICONV to build the old way. 1192 If you have been using WITH_ICONV before, you will very likely 1193 need to turn on WITH_LIBICONV_COMPAT. 1194 119520130806: 1196 INVARIANTS option now enables DEBUG for code with OpenSolaris and 1197 Illumos origin, including ZFS. If you have INVARIANTS in your 1198 kernel configuration, then there is no need to set DEBUG or ZFS_DEBUG 1199 explicitly. 1200 DEBUG used to enable witness(9) tracking of OpenSolaris (mostly ZFS) 1201 locks if WITNESS option was set. Because that generated a lot of 1202 witness(9) reports and all of them were believed to be false 1203 positives, this is no longer done. New option OPENSOLARIS_WITNESS 1204 can be used to achieve the previous behavior. 1205 120620130806: 1207 Timer values in IPv6 data structures now use time_uptime instead 1208 of time_second. Although this is not a user-visible functional 1209 change, userland utilities which directly use them---ndp(8), 1210 rtadvd(8), and rtsold(8) in the base system---need to be updated 1211 to r253970 or later. 1212 121320130802: 1214 find -delete can now delete the pathnames given as arguments, 1215 instead of only files found below them or if the pathname did 1216 not contain any slashes. Formerly, the following error message 1217 would result: 1218 1219 find: -delete: <path>: relative path potentially not safe 1220 1221 Deleting the pathnames given as arguments can be prevented 1222 without error messages using -mindepth 1 or by changing 1223 directory and passing "." as argument to find. This works in the 1224 old as well as the new version of find. 1225 122620130726: 1227 Behavior of devfs rules path matching has been changed. 1228 Pattern is now always matched against fully qualified devfs 1229 path and slash characters must be explicitly matched by 1230 slashes in pattern (FNM_PATHNAME). Rulesets involving devfs 1231 subdirectories must be reviewed. 1232 123320130716: 1234 The default ARM ABI has changed to the ARM EABI. The old ABI is 1235 incompatible with the ARM EABI and all programs and modules will 1236 need to be rebuilt to work with a new kernel. 1237 1238 To keep using the old ABI ensure the WITHOUT_ARM_EABI knob is set. 1239 1240 NOTE: Support for the old ABI will be removed in the future and 1241 users are advised to upgrade. 1242 124320130709: 1244 pkg_install has been disconnected from the build if you really need it 1245 you should add WITH_PKGTOOLS in your src.conf(5). 1246 124720130709: 1248 Most of network statistics structures were changed to be able 1249 keep 64-bits counters. Thus all tools, that work with networking 1250 statistics, must be rebuilt (netstat(1), bsnmpd(1), etc.) 1251 125220130618: 1253 Fix a bug that allowed a tracing process (e.g. gdb) to write 1254 to a memory-mapped file in the traced process's address space 1255 even if neither the traced process nor the tracing process had 1256 write access to that file. 1257 125820130615: 1259 CVS has been removed from the base system. An exact copy 1260 of the code is available from the devel/cvs port. 1261 126220130613: 1263 Some people report the following error after the switch to bmake: 1264 1265 make: illegal option -- J 1266 usage: make [-BPSXeiknpqrstv] [-C directory] [-D variable] 1267 ... 1268 *** [buildworld] Error code 2 1269 1270 this likely due to an old instance of make in 1271 ${MAKEPATH} (${MAKEOBJDIRPREFIX}${.CURDIR}/make.${MACHINE}) 1272 which src/Makefile will use that blindly, if it exists, so if 1273 you see the above error: 1274 1275 rm -rf `make -V MAKEPATH` 1276 1277 should resolve it. 1278 127920130516: 1280 Use bmake by default. 1281 Whereas before one could choose to build with bmake via 1282 -DWITH_BMAKE one must now use -DWITHOUT_BMAKE to use the old 1283 make. The goal is to remove these knobs for 10-RELEASE. 1284 1285 It is worth noting that bmake (like gmake) treats the command 1286 line as the unit of failure, rather than statements within the 1287 command line. Thus '(cd some/where && dosomething)' is safer 1288 than 'cd some/where; dosomething'. The '()' allows consistent 1289 behavior in parallel build. 1290 129120130429: 1292 Fix a bug that allows NFS clients to issue READDIR on files. 1293 129420130426: 1295 The WITHOUT_IDEA option has been removed because 1296 the IDEA patent expired. 1297 129820130426: 1299 The sysctl which controls TRIM support under ZFS has been renamed 1300 from vfs.zfs.trim_disable -> vfs.zfs.trim.enabled and has been 1301 enabled by default. 1302 130320130425: 1304 The mergemaster command now uses the default MAKEOBJDIRPREFIX 1305 rather than creating it's own in the temporary directory in 1306 order allow access to bootstrapped versions of tools such as 1307 install and mtree. When upgrading from version of FreeBSD where 1308 the install command does not support -l, you will need to 1309 install a new mergemaster command if mergemaster -p is required. 1310 This can be accomplished with the command (cd src/usr.sbin/mergemaster 1311 && make install). 1312 131320130404: 1314 Legacy ATA stack, disabled and replaced by new CAM-based one since 1315 FreeBSD 9.0, completely removed from the sources. Kernel modules 1316 atadisk and atapi*, user-level tools atacontrol and burncd are 1317 removed. Kernel option `options ATA_CAM` is now permanently enabled 1318 and removed. 1319 132020130319: 1321 SOCK_CLOEXEC and SOCK_NONBLOCK flags have been added to socket(2) 1322 and socketpair(2). Software, in particular Kerberos, may 1323 automatically detect and use these during building. The resulting 1324 binaries will not work on older kernels. 1325 132620130308: 1327 CTL_DISABLE has also been added to the sparc64 GENERIC (for further 1328 information, see the respective 20130304 entry). 1329 133020130304: 1331 Recent commits to callout(9) changed the size of struct callout, 1332 so the KBI is probably heavily disturbed. Also, some functions 1333 in callout(9)/sleep(9)/sleepqueue(9)/condvar(9) KPIs were replaced 1334 by macros. Every kernel module using it won't load, so rebuild 1335 is requested. 1336 1337 The ctl device has been re-enabled in GENERIC for i386 and amd64, 1338 but does not initialize by default (because of the new CTL_DISABLE 1339 option) to save memory. To re-enable it, remove the CTL_DISABLE 1340 option from the kernel config file or set kern.cam.ctl.disable=0 1341 in /boot/loader.conf. 1342 134320130301: 1344 The ctl device has been disabled in GENERIC for i386 and amd64. 1345 This was done due to the extra memory being allocated at system 1346 initialisation time by the ctl driver which was only used if 1347 a CAM target device was created. This makes a FreeBSD system 1348 unusable on 128MB or less of RAM. 1349 135020130208: 1351 A new compression method (lz4) has been merged to -HEAD. Please 1352 refer to zpool-features(7) for more information. 1353 1354 Please refer to the "ZFS notes" section of this file for information 1355 on upgrading boot ZFS pools. 1356 135720130129: 1358 A BSD-licensed patch(1) variant has been added and is installed 1359 as bsdpatch, being the GNU version the default patch. 1360 To inverse the logic and use the BSD-licensed one as default, 1361 while having the GNU version installed as gnupatch, rebuild 1362 and install world with the WITH_BSD_PATCH knob set. 1363 136420130121: 1365 Due to the use of the new -l option to install(1) during build 1366 and install, you must take care not to directly set the INSTALL 1367 make variable in your /etc/make.conf, /etc/src.conf, or on the 1368 command line. If you wish to use the -C flag for all installs 1369 you may be able to add INSTALL+=-C to /etc/make.conf or 1370 /etc/src.conf. 1371 137220130118: 1373 The install(1) option -M has changed meaning and now takes an 1374 argument that is a file or path to append logs to. In the 1375 unlikely event that -M was the last option on the command line 1376 and the command line contained at least two files and a target 1377 directory the first file will have logs appended to it. The -M 1378 option served little practical purpose in the last decade so its 1379 use is expected to be extremely rare. 1380 138120121223: 1382 After switching to Clang as the default compiler some users of ZFS 1383 on i386 systems started to experience stack overflow kernel panics. 1384 Please consider using 'options KSTACK_PAGES=4' in such configurations. 1385 138620121222: 1387 GEOM_LABEL now mangles label names read from file system metadata. 1388 Mangling affect labels containing spaces, non-printable characters, 1389 '%' or '"'. Device names in /etc/fstab and other places may need to 1390 be updated. 1391 139220121217: 1393 By default, only the 10 most recent kernel dumps will be saved. To 1394 restore the previous behaviour (no limit on the number of kernel dumps 1395 stored in the dump directory) add the following line to /etc/rc.conf: 1396 1397 savecore_flags="" 1398 139920121201: 1400 With the addition of auditdistd(8), a new auditdistd 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 140420121117: 1405 The sin6_scope_id member variable in struct sockaddr_in6 is now 1406 filled by the kernel before passing the structure to the userland via 1407 sysctl or routing socket. This means the KAME-specific embedded scope 1408 id in sin6_addr.s6_addr[2] is always cleared in userland application. 1409 This behavior can be controlled by net.inet6.ip6.deembed_scopeid. 1410 __FreeBSD_version is bumped to 1000025. 1411 141220121105: 1413 On i386 and amd64 systems WITH_CLANG_IS_CC is now the default. 1414 This means that the world and kernel will be compiled with clang 1415 and that clang will be installed as /usr/bin/cc, /usr/bin/c++, 1416 and /usr/bin/cpp. To disable this behavior and revert to building 1417 with gcc, compile with WITHOUT_CLANG_IS_CC. Really old versions 1418 of current may need to bootstrap WITHOUT_CLANG first if the clang 1419 build fails (its compatibility window doesn't extend to the 9 stable 1420 branch point). 1421 142220121102: 1423 The IPFIREWALL_FORWARD kernel option has been removed. Its 1424 functionality now turned on by default. 1425 142620121023: 1427 The ZERO_COPY_SOCKET kernel option has been removed and 1428 split into SOCKET_SEND_COW and SOCKET_RECV_PFLIP. 1429 NB: SOCKET_SEND_COW uses the VM page based copy-on-write 1430 mechanism which is not safe and may result in kernel crashes. 1431 NB: The SOCKET_RECV_PFLIP mechanism is useless as no current 1432 driver supports disposeable external page sized mbuf storage. 1433 Proper replacements for both zero-copy mechanisms are under 1434 consideration and will eventually lead to complete removal 1435 of the two kernel options. 1436 143720121023: 1438 The IPv4 network stack has been converted to network byte 1439 order. The following modules need to be recompiled together 1440 with kernel: carp(4), divert(4), gif(4), siftr(4), gre(4), 1441 pf(4), ipfw(4), ng_ipfw(4), stf(4). 1442 144320121022: 1444 Support for non-MPSAFE filesystems was removed from VFS. The 1445 VFS_VERSION was bumped, all filesystem modules shall be 1446 recompiled. 1447 144820121018: 1449 All the non-MPSAFE filesystems have been disconnected from 1450 the build. The full list includes: codafs, hpfs, ntfs, nwfs, 1451 portalfs, smbfs, xfs. 1452 145320121016: 1454 The interface cloning API and ABI has changed. The following 1455 modules need to be recompiled together with kernel: 1456 ipfw(4), pfsync(4), pflog(4), usb(4), wlan(4), stf(4), 1457 vlan(4), disc(4), edsc(4), if_bridge(4), gif(4), tap(4), 1458 faith(4), epair(4), enc(4), tun(4), if_lagg(4), gre(4). 1459 146020121015: 1461 The sdhci driver was split in two parts: sdhci (generic SD Host 1462 Controller logic) and sdhci_pci (actual hardware driver). 1463 No kernel config modifications are required, but if you 1464 load sdhc as a module you must switch to sdhci_pci instead. 1465 146620121014: 1467 Import the FUSE kernel and userland support into base system. 1468 146920121013: 1470 The GNU sort(1) program has been removed since the BSD-licensed 1471 sort(1) has been the default for quite some time and no serious 1472 problems have been reported. The corresponding WITH_GNU_SORT 1473 knob has also gone. 1474 147520121006: 1476 The pfil(9) API/ABI for AF_INET family has been changed. Packet 1477 filtering modules: pf(4), ipfw(4), ipfilter(4) need to be recompiled 1478 with new kernel. 1479 148020121001: 1481 The net80211(4) ABI has been changed to allow for improved driver 1482 PS-POLL and power-save support. All wireless drivers need to be 1483 recompiled to work with the new kernel. 1484 148520120913: 1486 The random(4) support for the VIA hardware random number 1487 generator (`PADLOCK') is no longer enabled unconditionally. 1488 Add the padlock_rng device in the custom kernel config if 1489 needed. The GENERIC kernels on i386 and amd64 do include the 1490 device, so the change only affects the custom kernel 1491 configurations. 1492 149320120908: 1494 The pf(4) packet filter ABI has been changed. pfctl(8) and 1495 snmp_pf module need to be recompiled to work with new kernel. 1496 149720120828: 1498 A new ZFS feature flag "com.delphix:empty_bpobj" has been merged 1499 to -HEAD. Pools that have empty_bpobj in active state can not be 1500 imported read-write with ZFS implementations that do not support 1501 this feature. For more information read the zpool-features(5) 1502 manual page. 1503 150420120727: 1505 The sparc64 ZFS loader has been changed to no longer try to auto- 1506 detect ZFS providers based on diskN aliases but now requires these 1507 to be explicitly listed in the OFW boot-device environment variable. 1508 150920120712: 1510 The OpenSSL has been upgraded to 1.0.1c. Any binaries requiring 1511 libcrypto.so.6 or libssl.so.6 must be recompiled. Also, there are 1512 configuration changes. Make sure to merge /etc/ssl/openssl.cnf. 1513 151420120712: 1515 The following sysctls and tunables have been renamed for consistency 1516 with other variables: 1517 kern.cam.da.da_send_ordered -> kern.cam.da.send_ordered 1518 kern.cam.ada.ada_send_ordered -> kern.cam.ada.send_ordered 1519 152020120628: 1521 The sort utility has been replaced with BSD sort. For now, GNU sort 1522 is also available as "gnusort" or the default can be set back to 1523 GNU sort by setting WITH_GNU_SORT. In this case, BSD sort will be 1524 installed as "bsdsort". 1525 152620120611: 1527 A new version of ZFS (pool version 5000) has been merged to -HEAD. 1528 Starting with this version the old system of ZFS pool versioning 1529 is superseded by "feature flags". This concept enables forward 1530 compatibility against certain future changes in functionality of ZFS 1531 pools. The first read-only compatible "feature flag" for ZFS pools 1532 is named "com.delphix:async_destroy". For more information 1533 read the new zpool-features(5) manual page. 1534 Please refer to the "ZFS notes" section of this file for information 1535 on upgrading boot ZFS pools. 1536 153720120417: 1538 The malloc(3) implementation embedded in libc now uses sources imported 1539 as contrib/jemalloc. The most disruptive API change is to 1540 /etc/malloc.conf. If your system has an old-style /etc/malloc.conf, 1541 delete it prior to installworld, and optionally re-create it using the 1542 new format after rebooting. See malloc.conf(5) for details 1543 (specifically the TUNING section and the "opt.*" entries in the MALLCTL 1544 NAMESPACE section). 1545 154620120328: 1547 Big-endian MIPS TARGET_ARCH values no longer end in "eb". mips64eb 1548 is now spelled mips64. mipsn32eb is now spelled mipsn32. mipseb is 1549 now spelled mips. This is to aid compatibility with third-party 1550 software that expects this naming scheme in uname(3). Little-endian 1551 settings are unchanged. If you are updating a big-endian mips64 machine 1552 from before this change, you may need to set MACHINE_ARCH=mips64 in 1553 your environment before the new build system will recognize your machine. 1554 155520120306: 1556 Disable by default the option VFS_ALLOW_NONMPSAFE for all supported 1557 platforms. 1558 155920120229: 1560 Now unix domain sockets behave "as expected" on nullfs(5). Previously 1561 nullfs(5) did not pass through all behaviours to the underlying layer, 1562 as a result if we bound to a socket on the lower layer we could connect 1563 only to the lower path; if we bound to the upper layer we could connect 1564 only to the upper path. The new behavior is one can connect to both the 1565 lower and the upper paths regardless what layer path one binds to. 1566 156720120211: 1568 The getifaddrs upgrade path broken with 20111215 has been restored. 1569 If you have upgraded in between 20111215 and 20120209 you need to 1570 recompile libc again with your kernel. You still need to recompile 1571 world to be able to configure CARP but this restriction already 1572 comes from 20111215. 1573 157420120114: 1575 The set_rcvar() function has been removed from /etc/rc.subr. All 1576 base and ports rc.d scripts have been updated, so if you have a 1577 port installed with a script in /usr/local/etc/rc.d you can either 1578 hand-edit the rcvar= line, or reinstall the port. 1579 1580 An easy way to handle the mass-update of /etc/rc.d: 1581 rm /etc/rc.d/* && mergemaster -i 1582 158320120109: 1584 panic(9) now stops other CPUs in the SMP systems, disables interrupts 1585 on the current CPU and prevents other threads from running. 1586 This behavior can be reverted using the kern.stop_scheduler_on_panic 1587 tunable/sysctl. 1588 The new behavior can be incompatible with kern.sync_on_panic. 1589 159020111215: 1591 The carp(4) facility has been changed significantly. Configuration 1592 of the CARP protocol via ifconfig(8) has changed, as well as format 1593 of CARP events submitted to devd(8) has changed. See manual pages 1594 for more information. The arpbalance feature of carp(4) is currently 1595 not supported anymore. 1596 1597 Size of struct in_aliasreq, struct in6_aliasreq has changed. User 1598 utilities using SIOCAIFADDR, SIOCAIFADDR_IN6, e.g. ifconfig(8), 1599 need to be recompiled. 1600 160120111122: 1602 The acpi_wmi(4) status device /dev/wmistat has been renamed to 1603 /dev/wmistat0. 1604 160520111108: 1606 The option VFS_ALLOW_NONMPSAFE option has been added in order to 1607 explicitely support non-MPSAFE filesystems. 1608 It is on by default for all supported platform at this present 1609 time. 1610 161120111101: 1612 The broken amd(4) driver has been replaced with esp(4) in the amd64, 1613 i386 and pc98 GENERIC kernel configuration files. 1614 161520110930: 1616 sysinstall has been removed 1617 161820110923: 1619 The stable/9 branch created in subversion. This corresponds to the 1620 RELENG_9 branch in CVS. 1621 1622COMMON ITEMS: 1623 1624 General Notes 1625 ------------- 1626 Avoid using make -j when upgrading. While generally safe, there are 1627 sometimes problems using -j to upgrade. If your upgrade fails with 1628 -j, please try again without -j. From time to time in the past there 1629 have been problems using -j with buildworld and/or installworld. This 1630 is especially true when upgrading between "distant" versions (eg one 1631 that cross a major release boundary or several minor releases, or when 1632 several months have passed on the -current branch). 1633 1634 Sometimes, obscure build problems are the result of environment 1635 poisoning. This can happen because the make utility reads its 1636 environment when searching for values for global variables. To run 1637 your build attempts in an "environmental clean room", prefix all make 1638 commands with 'env -i '. See the env(1) manual page for more details. 1639 1640 When upgrading from one major version to another it is generally best 1641 to upgrade to the latest code in the currently installed branch first, 1642 then do an upgrade to the new branch. This is the best-tested upgrade 1643 path, and has the highest probability of being successful. Please try 1644 this approach before reporting problems with a major version upgrade. 1645 1646 When upgrading a live system, having a root shell around before 1647 installing anything can help undo problems. Not having a root shell 1648 around can lead to problems if pam has changed too much from your 1649 starting point to allow continued authentication after the upgrade. 1650 1651 This file should be read as a log of events. When a later event changes 1652 information of a prior event, the prior event should not be deleted. 1653 Instead, a pointer to the entry with the new information should be 1654 placed in the old entry. Readers of this file should also sanity check 1655 older entries before relying on them blindly. Authors of new entries 1656 should write them with this in mind. 1657 1658 ZFS notes 1659 --------- 1660 When upgrading the boot ZFS pool to a new version, always follow 1661 these two steps: 1662 1663 1.) recompile and reinstall the ZFS boot loader and boot block 1664 (this is part of "make buildworld" and "make installworld") 1665 1666 2.) update the ZFS boot block on your boot drive 1667 1668 The following example updates the ZFS boot block on the first 1669 partition (freebsd-boot) of a GPT partitioned drive ada0: 1670 "gpart bootcode -p /boot/gptzfsboot -i 1 ada0" 1671 1672 Non-boot pools do not need these updates. 1673 1674 To build a kernel 1675 ----------------- 1676 If you are updating from a prior version of FreeBSD (even one just 1677 a few days old), you should follow this procedure. It is the most 1678 failsafe as it uses a /usr/obj tree with a fresh mini-buildworld, 1679 1680 make kernel-toolchain 1681 make -DALWAYS_CHECK_MAKE buildkernel KERNCONF=YOUR_KERNEL_HERE 1682 make -DALWAYS_CHECK_MAKE installkernel KERNCONF=YOUR_KERNEL_HERE 1683 1684 To test a kernel once 1685 --------------------- 1686 If you just want to boot a kernel once (because you are not sure 1687 if it works, or if you want to boot a known bad kernel to provide 1688 debugging information) run 1689 make installkernel KERNCONF=YOUR_KERNEL_HERE KODIR=/boot/testkernel 1690 nextboot -k testkernel 1691 1692 To just build a kernel when you know that it won't mess you up 1693 -------------------------------------------------------------- 1694 This assumes you are already running a CURRENT system. Replace 1695 ${arch} with the architecture of your machine (e.g. "i386", 1696 "arm", "amd64", "ia64", "pc98", "sparc64", "powerpc", "mips", etc). 1697 1698 cd src/sys/${arch}/conf 1699 config KERNEL_NAME_HERE 1700 cd ../compile/KERNEL_NAME_HERE 1701 make depend 1702 make 1703 make install 1704 1705 If this fails, go to the "To build a kernel" section. 1706 1707 To rebuild everything and install it on the current system. 1708 ----------------------------------------------------------- 1709 # Note: sometimes if you are running current you gotta do more than 1710 # is listed here if you are upgrading from a really old current. 1711 1712 <make sure you have good level 0 dumps> 1713 make buildworld 1714 make kernel KERNCONF=YOUR_KERNEL_HERE 1715 [1] 1716 <reboot in single user> [3] 1717 mergemaster -Fp [5] 1718 make installworld 1719 mergemaster -Fi [4] 1720 make delete-old [6] 1721 <reboot> 1722 1723 To cross-install current onto a separate partition 1724 -------------------------------------------------- 1725 # In this approach we use a separate partition to hold 1726 # current's root, 'usr', and 'var' directories. A partition 1727 # holding "/", "/usr" and "/var" should be about 2GB in 1728 # size. 1729 1730 <make sure you have good level 0 dumps> 1731 <boot into -stable> 1732 make buildworld 1733 make buildkernel KERNCONF=YOUR_KERNEL_HERE 1734 <maybe newfs current's root partition> 1735 <mount current's root partition on directory ${CURRENT_ROOT}> 1736 make installworld DESTDIR=${CURRENT_ROOT} -DDB_FROM_SRC 1737 make distribution DESTDIR=${CURRENT_ROOT} # if newfs'd 1738 make installkernel KERNCONF=YOUR_KERNEL_HERE DESTDIR=${CURRENT_ROOT} 1739 cp /etc/fstab ${CURRENT_ROOT}/etc/fstab # if newfs'd 1740 <edit ${CURRENT_ROOT}/etc/fstab to mount "/" from the correct partition> 1741 <reboot into current> 1742 <do a "native" rebuild/install as described in the previous section> 1743 <maybe install compatibility libraries from ports/misc/compat*> 1744 <reboot> 1745 1746 1747 To upgrade in-place from stable to current 1748 ---------------------------------------------- 1749 <make sure you have good level 0 dumps> 1750 make buildworld [9] 1751 make kernel KERNCONF=YOUR_KERNEL_HERE [8] 1752 [1] 1753 <reboot in single user> [3] 1754 mergemaster -Fp [5] 1755 make installworld 1756 mergemaster -Fi [4] 1757 make delete-old [6] 1758 <reboot> 1759 1760 Make sure that you've read the UPDATING file to understand the 1761 tweaks to various things you need. At this point in the life 1762 cycle of current, things change often and you are on your own 1763 to cope. The defaults can also change, so please read ALL of 1764 the UPDATING entries. 1765 1766 Also, if you are tracking -current, you must be subscribed to 1767 freebsd-current@freebsd.org. Make sure that before you update 1768 your sources that you have read and understood all the recent 1769 messages there. If in doubt, please track -stable which has 1770 much fewer pitfalls. 1771 1772 [1] If you have third party modules, such as vmware, you 1773 should disable them at this point so they don't crash your 1774 system on reboot. 1775 1776 [3] From the bootblocks, boot -s, and then do 1777 fsck -p 1778 mount -u / 1779 mount -a 1780 cd src 1781 adjkerntz -i # if CMOS is wall time 1782 Also, when doing a major release upgrade, it is required that 1783 you boot into single user mode to do the installworld. 1784 1785 [4] Note: This step is non-optional. Failure to do this step 1786 can result in a significant reduction in the functionality of the 1787 system. Attempting to do it by hand is not recommended and those 1788 that pursue this avenue should read this file carefully, as well 1789 as the archives of freebsd-current and freebsd-hackers mailing lists 1790 for potential gotchas. The -U option is also useful to consider. 1791 See mergemaster(8) for more information. 1792 1793 [5] Usually this step is a noop. However, from time to time 1794 you may need to do this if you get unknown user in the following 1795 step. It never hurts to do it all the time. You may need to 1796 install a new mergemaster (cd src/usr.sbin/mergemaster && make 1797 install) after the buildworld before this step if you last updated 1798 from current before 20130425 or from -stable before 20130430. 1799 1800 [6] This only deletes old files and directories. Old libraries 1801 can be deleted by "make delete-old-libs", but you have to make 1802 sure that no program is using those libraries anymore. 1803 1804 [8] The new kernel must be able to run existing binaries used by 1805 an installworld. When upgrading across major versions, the new 1806 kernel's configuration must include the correct COMPAT_FREEBSD<n> 1807 option for existing binaries (e.g. COMPAT_FREEBSD11 to run 11.x 1808 binaries). Failure to do so may leave you with a system that is 1809 hard to boot to recover. A GENERIC kernel will include suitable 1810 compatibility options to run binaries from older branches. 1811 1812 Make sure that you merge any new devices from GENERIC since the 1813 last time you updated your kernel config file. 1814 1815 [9] When checking out sources, you must include the -P flag to have 1816 cvs prune empty directories. 1817 1818 If CPUTYPE is defined in your /etc/make.conf, make sure to use the 1819 "?=" instead of the "=" assignment operator, so that buildworld can 1820 override the CPUTYPE if it needs to. 1821 1822 MAKEOBJDIRPREFIX must be defined in an environment variable, and 1823 not on the command line, or in /etc/make.conf. buildworld will 1824 warn if it is improperly defined. 1825FORMAT: 1826 1827This file contains a list, in reverse chronological order, of major 1828breakages in tracking -current. It is not guaranteed to be a complete 1829list of such breakages, and only contains entries since September 23, 2011. 1830If you need to see UPDATING entries from before that date, you will need 1831to fetch an UPDATING file from an older FreeBSD release. 1832 1833Copyright information: 1834 1835Copyright 1998-2009 M.
