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 http://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 from 17older version of current across the gcc/clang cutover is a bit fragile. 18 19NOTE TO PEOPLE WHO THINK THAT FreeBSD 11.x IS SLOW: 20 FreeBSD 11.x has many debugging features turned on, in both the kernel 21 and userland. These features attempt to detect incorrect use of 22 system primitives, and encourage loud failure through extra sanity 23 checking and fail stop semantics. They also substantially impact 24 system performance. If you want to do performance measurement, 25 benchmarking, and optimization, you'll want to turn them off. This 26 includes various WITNESS- related kernel options, INVARIANTS, malloc 27 debugging flags in userland, and various verbose features in the 28 kernel. Many developers choose to disable these features on build 29 machines to maximize performance. (To completely disable malloc 30 debugging, define MALLOC_PRODUCTION in /etc/make.conf, or to merely 31 disable the most expensive debugging functionality run 32 "ln -s 'abort:false,junk:false' /etc/malloc.conf".) 33 3420150813: 35 The WITHOUT_ELFTOOLCHAIN_TOOLS src.conf(5) knob has been retired. 36 Control over building the ELF Tool Chain tools is now provided by 37 the WITHOUT_TOOLCHAIN knob. 38 3920150810: 40 The polarity of Pulse Per Second (PPS) capture events with the 41 uart(4) driver has been corrected. Prior to this change the PPS 42 "assert" event corresponded to the trailing edge of a positive PPS 43 pulse and the "clear" event was the leading edge of the next pulse. 44 45 As the width of a PPS pulse in a typical GPS receiver is on the 46 order of 1 millisecond, most users will not notice any significant 47 difference with this change. 48 49 Anyone who has compensated for the historical polarity reversal by 50 configuring a negative offset equal to the pulse width will need to 51 remove that workaround. 52 5320150809: 54 The default group assigned to /dev/dri entries has been changed 55 from 'wheel' to 'video' with the id of '44'. If you want to have 56 access to the dri devices please add yourself to the video group 57 with: 58 59 # pw groupmod video -m $USER 60 6120150806: 62 The menu.rc and loader.rc files will now be replaced during 63 upgrades. Please migrate local changes to menu.rc.local and 64 loader.rc.local instead. 65 6620150805: 67 GNU Binutils versions of addr2line, c++filt, nm, readelf, size, 68 strings and strip have been removed. The src.conf(5) knob 69 WITHOUT_ELFTOOLCHAIN_TOOLS no longer provides the binutils tools. 70 7120150728: 72 As ZFS requires more kernel stack pages than is the default on some 73 architectures e.g. i386, it now warns if KSTACK_PAGES is less than 74 ZFS_MIN_KSTACK_PAGES (which is 4 at the time of writing). 75 76 Please consider using 'options KSTACK_PAGES=X' where X is greater 77 than or equal to ZFS_MIN_KSTACK_PAGES i.e. 4 in such configurations. 78 7920150706: 80 sendmail has been updated to 8.15.2. Starting with FreeBSD 11.0 81 and sendmail 8.15, sendmail uses uncompressed IPv6 addresses by 82 default, i.e., they will not contain "::". For example, instead 83 of ::1, it will be 0:0:0:0:0:0:0:1. This permits a zero subnet 84 to have a more specific match, such as different map entries for 85 IPv6:0:0 vs IPv6:0. This change requires that configuration 86 data (including maps, files, classes, custom ruleset, etc.) must 87 use the same format, so make certain such configuration data is 88 upgrading. As a very simple check search for patterns like 89 'IPv6:[0-9a-fA-F:]*::' and 'IPv6::'. To return to the old 90 behavior, set the m4 option confUSE_COMPRESSED_IPV6_ADDRESSES or 91 the cf option UseCompressedIPv6Addresses. 92 9320150630: 94 The default kernel entropy-processing algorithm is now 95 Fortuna, replacing Yarrow. 96 97 Assuming you have 'device random' in your kernel config 98 file, the configurations allow a kernel option to override 99 this default. You may choose *ONE* of: 100 101 options RANDOM_YARROW # Legacy /dev/random algorithm. 102 options RANDOM_DUMMY # Blocking-only driver. 103 104 If you have neither, you get Fortuna. For most people, 105 read no further, Fortuna will give a /dev/random that works 106 like it always used to, and the difference will be irrelevant. 107 108 If you remove 'device random', you get *NO* kernel-processed 109 entopy at all. This may be acceptable to folks building 110 embedded systems, but has complications. Carry on reading, 111 and it is assumed you know what you need. 112 113 *PLEASE* read random(4) and random(9) if you are in the 114 habit of tweeking kernel configs, and/or if you are a member 115 of the embedded community, wanting specific and not-usual 116 behaviour from your security subsystems. 117 118 NOTE!! If you use RANDOM_DUMMY and/or have no 'device 119 random', you will NOT have a functioning /dev/random, and 120 many cryptographic features will not work, including SSH. 121 You may also find strange behaviour from the random(3) set 122 of library functions, in particular sranddev(3), srandomdev(3) 123 and arc4random(3). The reason for this is that the KERN_ARND 124 sysctl only returns entropy if it thinks it has some to 125 share, and with RANDOM_DUMMY or no 'device random' this 126 will never happen. 127 12820150623: 129 An additional fix for the issue described in the 20150614 sendmail 130 entry below has been been committed in revision 284717. 131 13220150616: 133 FreeBSD's old make (fmake) has been removed from the system. It is 134 available as the devel/fmake port or via pkg install fmake. 135 13620150615: 137 The fix for the issue described in the 20150614 sendmail entry 138 below has been been committed in revision 284436. The work 139 around described in that entry is no longer needed unless the 140 default setting is overridden by a confDH_PARAMETERS configuration 141 setting of '5' or pointing to a 512 bit DH parameter file. 142 14320150614: 144 ALLOW_DEPRECATED_ATF_TOOLS/ATFFILE support has been removed from 145 atf.test.mk (included from bsd.test.mk). Please upgrade devel/atf 146 and devel/kyua to version 0.20+ and adjust any calling code to work 147 with Kyuafile and kyua. 148 14920150614: 150 The import of openssl to address the FreeBSD-SA-15:10.openssl 151 security advisory includes a change which rejects handshakes 152 with DH parameters below 768 bits. sendmail releases prior 153 to 8.15.2 (not yet released), defaulted to a 512 bit 154 DH parameter setting for client connections. To work around 155 this interoperability, sendmail can be configured to use a 156 2048 bit DH parameter by: 157 158 1. Edit /etc/mail/`hostname`.mc 159 2. If a setting for confDH_PARAMETERS does not exist or 160 exists and is set to a string beginning with '5', 161 replace it with '2'. 162 3. If a setting for confDH_PARAMETERS exists and is set to 163 a file path, create a new file with: 164 openssl dhparam -out /path/to/file 2048 165 4. Rebuild the .cf file: 166 cd /etc/mail/; make; make install 167 5. Restart sendmail: 168 cd /etc/mail/; make restart 169 170 A sendmail patch is coming, at which time this file will be 171 updated. 172 17320150604: 174 Generation of legacy formatted entries have been disabled by default 175 in pwd_mkdb(8), as all base system consumers of the legacy formatted 176 entries were converted to use the new format by default when the new, 177 machine independent format have been added and supported since FreeBSD 178 5.x. 179 180 Please see the pwd_mkdb(8) manual page for further details. 181 18220150525: 183 Clang and llvm have been upgraded to 3.6.1 release. Please see the 184 20141231 entry below for information about prerequisites and upgrading, 185 if you are not already using 3.5.0 or higher. 186 18720150521: 188 TI platform code switched to using vendor DTS files and this update 189 may break existing systems running on Beaglebone, Beaglebone Black, 190 and Pandaboard: 191 192 - dtb files should be regenerated/reinstalled. Filenames are the 193 same but content is different now 194 - GPIO addressing was changed, now each GPIO bank (32 pins per bank) 195 has its own /dev/gpiocX device, e.g. pin 121 on /dev/gpioc0 in old 196 addressing scheme is now pin 25 on /dev/gpioc3. 197 - Pandaboard: /etc/ttys should be updated, serial console device is 198 now /dev/ttyu2, not /dev/ttyu0 199 20020150501: 201 soelim(1) from gnu/usr.bin/groff has been replaced by usr.bin/soelim. 202 If you need the GNU extension from groff soelim(1), install groff 203 from package: pkg install groff, or via ports: textproc/groff. 204 20520150423: 206 chmod, chflags, chown and chgrp now affect symlinks in -R mode as 207 defined in symlink(7); previously symlinks were silently ignored. 208 20920150415: 210 The const qualifier has been removed from iconv(3) to comply with 211 POSIX. The ports tree is aware of this from r384038 onwards. 212 21320150416: 214 Libraries specified by LIBADD in Makefiles must have a corresponding 215 DPADD_<lib> variable to ensure correct dependencies. This is now 216 enforced in src.libnames.mk. 217 21820150324: 219 From legacy ata(4) driver was removed support for SATA controllers 220 supported by more functional drivers ahci(4), siis(4) and mvs(4). 221 Kernel modules ataahci and ataadaptec were removed completely, 222 replaced by ahci and mvs modules respectively. 223 22420150315: 225 Clang, llvm and lldb have been upgraded to 3.6.0 release. Please see 226 the 20141231 entry below for information about prerequisites and 227 upgrading, if you are not already using 3.5.0 or higher. 228 22920150307: 230 The 32-bit PowerPC kernel has been changed to a position-independent 231 executable. This can only be booted with a version of loader(8) 232 newer than January 31, 2015, so make sure to update both world and 233 kernel before rebooting. 234 23520150217: 236 If you are running a -CURRENT kernel since r273872 (Oct 30th, 2014), 237 but before r278950, the RNG was not seeded properly. Immediately 238 upgrade the kernel to r278950 or later and regenerate any keys (e.g. 239 ssh keys or openssl keys) that were generated w/ a kernel from that 240 range. This does not affect programs that directly used /dev/random 241 or /dev/urandom. All userland uses of arc4random(3) are affected. 242 24320150210: 244 The autofs(4) ABI was changed in order to restore binary compatibility 245 with 10.1-RELEASE. The automountd(8) daemon needs to be rebuilt to work 246 with the new kernel. 247 24820150131: 249 The powerpc64 kernel has been changed to a position-independent 250 executable. This can only be booted with a new version of loader(8), 251 so make sure to update both world and kernel before rebooting. 252 25320150118: 254 Clang and llvm have been upgraded to 3.5.1 release. This is a bugfix 255 only release, no new features have been added. Please see the 20141231 256 entry below for information about prerequisites and upgrading, if you 257 are not already using 3.5.0. 258 25920150107: 260 ELF tools addr2line, elfcopy (strip), nm, size, and strings are now 261 taken from the ELF Tool Chain project rather than GNU binutils. They 262 should be drop-in replacements, with the addition of arm64 support. 263 The WITHOUT_ELFTOOLCHAIN_TOOLS= knob may be used to obtain the 264 binutils tools, if necessary. See 20150805 for updated information. 265 26620150105: 267 The default Unbound configuration now enables remote control 268 using a local socket. Users who have already enabled the 269 local_unbound service should regenerate their configuration 270 by running "service local_unbound setup" as root. 271 27220150102: 273 The GNU texinfo and GNU info pages have been removed. 274 To be able to view GNU info pages please install texinfo from ports. 275 27620141231: 277 Clang, llvm and lldb have been upgraded to 3.5.0 release. 278 279 As of this release, a prerequisite for building clang, llvm and lldb is 280 a C++11 capable compiler and C++11 standard library. This means that to 281 be able to successfully build the cross-tools stage of buildworld, with 282 clang as the bootstrap compiler, your system compiler or cross compiler 283 should either be clang 3.3 or later, or gcc 4.8 or later, and your 284 system C++ library should be libc++, or libdstdc++ from gcc 4.8 or 285 later. 286 287 On any standard FreeBSD 10.x or 11.x installation, where clang and 288 libc++ are on by default (that is, on x86 or arm), this should work out 289 of the box. 290 291 On 9.x installations where clang is enabled by default, e.g. on x86 and 292 powerpc, libc++ will not be enabled by default, so libc++ should be 293 built (with clang) and installed first. If both clang and libc++ are 294 missing, build clang first, then use it to build libc++. 295 296 On 8.x and earlier installations, upgrade to 9.x first, and then follow 297 the instructions for 9.x above. 298 299 Sparc64 and mips users are unaffected, as they still use gcc 4.2.1 by 300 default, and do not build clang. 301 302 Many embedded systems are resource constrained, and will not be able to 303 build clang in a reasonable time, or in some cases at all. In those 304 cases, cross building bootable systems on amd64 is a workaround. 305 306 This new version of clang introduces a number of new warnings, of which 307 the following are most likely to appear: 308 309 -Wabsolute-value 310 311 This warns in two cases, for both C and C++: 312 * When the code is trying to take the absolute value of an unsigned 313 quantity, which is effectively a no-op, and almost never what was 314 intended. The code should be fixed, if at all possible. If you are 315 sure that the unsigned quantity can be safely cast to signed, without 316 loss of information or undefined behavior, you can add an explicit 317 cast, or disable the warning. 318 319 * When the code is trying to take an absolute value, but the called 320 abs() variant is for the wrong type, which can lead to truncation. 321 If you want to disable the warning instead of fixing the code, please 322 make sure that truncation will not occur, or it might lead to unwanted 323 side-effects. 324 325 -Wtautological-undefined-compare and 326 -Wundefined-bool-conversion 327 328 These warn when C++ code is trying to compare 'this' against NULL, while 329 'this' should never be NULL in well-defined C++ code. However, there is 330 some legacy (pre C++11) code out there, which actively abuses this 331 feature, which was less strictly defined in previous C++ versions. 332 333 Squid and openjdk do this, for example. The warning can be turned off 334 for C++98 and earlier, but compiling the code in C++11 mode might result 335 in unexpected behavior; for example, the parts of the program that are 336 unreachable could be optimized away. 337 33820141222: 339 The old NFS client and server (kernel options NFSCLIENT, NFSSERVER) 340 kernel sources have been removed. The .h files remain, since some 341 utilities include them. This will need to be fixed later. 342 If "mount -t oldnfs ..." is attempted, it will fail. 343 If the "-o" option on mountd(8), nfsd(8) or nfsstat(1) is used, 344 the utilities will report errors. 345 34620141121: 347 The handling of LOCAL_LIB_DIRS has been altered to skip addition of 348 directories to top level SUBDIR variable when their parent 349 directory is included in LOCAL_DIRS. Users with build systems with 350 such hierarchies and without SUBDIR entries in the parent 351 directory Makefiles should add them or add the directories to 352 LOCAL_DIRS. 353 35420141109: 355 faith(4) and faithd(8) have been removed from the base system. Faith 356 has been obsolete for a very long time. 357 35820141104: 359 vt(4), the new console driver, is enabled by default. It brings 360 support for Unicode and double-width characters, as well as 361 support for UEFI and integration with the KMS kernel video 362 drivers. 363 364 You may need to update your console settings in /etc/rc.conf, 365 most probably the keymap. During boot, /etc/rc.d/syscons will 366 indicate what you need to do. 367 368 vt(4) still has issues and lacks some features compared to 369 syscons(4). See the wiki for up-to-date information: 370 https://wiki.freebsd.org/Newcons 371 372 If you want to keep using syscons(4), you can do so by adding 373 the following line to /boot/loader.conf: 374 kern.vty=sc 375 37620141102: 377 pjdfstest has been integrated into kyua as an opt-in test suite. 378 Please see share/doc/pjdfstest/README for more details on how to 379 execute it. 380 38120141009: 382 gperf has been removed from the base system for architectures 383 that use clang. Ports that require gperf will obtain it from the 384 devel/gperf port. 385 38620140923: 387 pjdfstest has been moved from tools/regression/pjdfstest to 388 contrib/pjdfstest . 389 39020140922: 391 At svn r271982, The default linux compat kernel ABI has been adjusted 392 to 2.6.18 in support of the linux-c6 compat ports infrastructure 393 update. If you wish to continue using the linux-f10 compat ports, 394 add compat.linux.osrelease=2.6.16 to your local sysctl.conf. Users are 395 encouraged to update their linux-compat packages to linux-c6 during 396 their next update cycle. 397 39820140729: 399 The ofwfb driver, used to provide a graphics console on PowerPC when 400 using vt(4), no longer allows mmap() of all physical memory. This 401 will prevent Xorg on PowerPC with some ATI graphics cards from 402 initializing properly unless x11-servers/xorg-server is updated to 403 1.12.4_8 or newer. 404 40520140723: 406 The xdev targets have been converted to using TARGET and 407 TARGET_ARCH instead of XDEV and XDEV_ARCH. 408 40920140719: 410 The default unbound configuration has been modified to address 411 issues with reverse lookups on networks that use private 412 address ranges. If you use the local_unbound service, run 413 "service local_unbound setup" as root to regenerate your 414 configuration, then "service local_unbound reload" to load the 415 new configuration. 416 41720140709: 418 The GNU texinfo and GNU info pages are not built and installed 419 anymore, WITH_INFO knob has been added to allow to built and install 420 them again. 421 UPDATE: see 20150102 entry on texinfo's removal 422 42320140708: 424 The GNU readline library is now an INTERNALLIB - that is, it is 425 statically linked into consumers (GDB and variants) in the base 426 system, and the shared library is no longer installed. The 427 devel/readline port is available for third party software that 428 requires readline. 429 43020140702: 431 The Itanium architecture (ia64) has been removed from the list of 432 known architectures. This is the first step in the removal of the 433 architecture. 434 43520140701: 436 Commit r268115 has added NFSv4.1 server support, merged from 437 projects/nfsv4.1-server. Since this includes changes to the 438 internal interfaces between the NFS related modules, a full 439 build of the kernel and modules will be necessary. 440 __FreeBSD_version has been bumped. 441 44220140629: 443 The WITHOUT_VT_SUPPORT kernel config knob has been renamed 444 WITHOUT_VT. (The other _SUPPORT knobs have a consistent meaning 445 which differs from the behaviour controlled by this knob.) 446 44720140619: 448 Maximal length of the serial number in CTL was increased from 16 to 449 64 chars, that breaks ABI. All CTL-related tools, such as ctladm 450 and ctld, need to be rebuilt to work with a new kernel. 451 45220140606: 453 The libatf-c and libatf-c++ major versions were downgraded to 0 and 454 1 respectively to match the upstream numbers. They were out of 455 sync because, when they were originally added to FreeBSD, the 456 upstream versions were not respected. These libraries are private 457 and not yet built by default, so renumbering them should be a 458 non-issue. However, unclean source trees will yield broken test 459 programs once the operator executes "make delete-old-libs" after a 460 "make installworld". 461 462 Additionally, the atf-sh binary was made private by moving it into 463 /usr/libexec/. Already-built shell test programs will keep the 464 path to the old binary so they will break after "make delete-old" 465 is run. 466 467 If you are using WITH_TESTS=yes (not the default), wipe the object 468 tree and rebuild from scratch to prevent spurious test failures. 469 This is only needed once: the misnumbered libraries and misplaced 470 binaries have been added to OptionalObsoleteFiles.inc so they will 471 be removed during a clean upgrade. 472 47320140512: 474 Clang and llvm have been upgraded to 3.4.1 release. 475 47620140508: 477 We bogusly installed src.opts.mk in /usr/share/mk. This file should 478 be removed to avoid issues in the future (and has been added to 479 ObsoleteFiles.inc). 480 48120140505: 482 /etc/src.conf now affects only builds of the FreeBSD src tree. In the 483 past, it affected all builds that used the bsd.*.mk files. The old 484 behavior was a bug, but people may have relied upon it. To get this 485 behavior back, you can .include /etc/src.conf from /etc/make.conf 486 (which is still global and isn't changed). This also changes the 487 behavior of incremental builds inside the tree of individual 488 directories. Set MAKESYSPATH to ".../share/mk" to do that. 489 Although this has survived make universe and some upgrade scenarios, 490 other upgrade scenarios may have broken. At least one form of 491 temporary breakage was fixed with MAKESYSPATH settings for buildworld 492 as well... In cases where MAKESYSPATH isn't working with this 493 setting, you'll need to set it to the full path to your tree. 494 495 One side effect of all this cleaning up is that bsd.compiler.mk 496 is no longer implicitly included by bsd.own.mk. If you wish to 497 use COMPILER_TYPE, you must now explicitly include bsd.compiler.mk 498 as well. 499 50020140430: 501 The lindev device has been removed since /dev/full has been made a 502 standard device. __FreeBSD_version has been bumped. 503 50420140424: 505 The knob WITHOUT_VI was added to the base system, which controls 506 building ex(1), vi(1), etc. Older releases of FreeBSD required ex(1) 507 in order to reorder files share/termcap and didn't build ex(1) as a 508 build tool, so building/installing with WITH_VI is highly advised for 509 build hosts for older releases. 510 511 This issue has been fixed in stable/9 and stable/10 in r277022 and 512 r276991, respectively. 513 51420140418: 515 The YES_HESIOD knob has been removed. It has been obsolete for 516 a decade. Please move to using WITH_HESIOD instead or your builds 517 will silently lack HESIOD. 518 51920140405: 520 The uart(4) driver has been changed with respect to its handling 521 of the low-level console. Previously the uart(4) driver prevented 522 any process from changing the baudrate or the CLOCAL and HUPCL 523 control flags. By removing the restrictions, operators can make 524 changes to the serial console port without having to reboot. 525 However, when getty(8) is started on the serial device that is 526 associated with the low-level console, a misconfigured terminal 527 line in /etc/ttys will now have a real impact. 528 Before upgrading the kernel, make sure that /etc/ttys has the 529 serial console device configured as 3wire without baudrate to 530 preserve the previous behaviour. E.g: 531 ttyu0 "/usr/libexec/getty 3wire" vt100 on secure 532 53320140306: 534 Support for libwrap (TCP wrappers) in rpcbind was disabled by default 535 to improve performance. To re-enable it, if needed, run rpcbind 536 with command line option -W. 537 53820140226: 539 Switched back to the GPL dtc compiler due to updates in the upstream 540 dts files not being supported by the BSDL dtc compiler. You will need 541 to rebuild your kernel toolchain to pick up the new compiler. Core dumps 542 may result while building dtb files during a kernel build if you fail 543 to do so. Set WITHOUT_GPL_DTC if you require the BSDL compiler. 544 54520140216: 546 Clang and llvm have been upgraded to 3.4 release. 547 54820140216: 549 The nve(4) driver has been removed. Please use the nfe(4) driver 550 for NVIDIA nForce MCP Ethernet adapters instead. 551 55220140212: 553 An ABI incompatibility crept into the libc++ 3.4 import in r261283. 554 This could cause certain C++ applications using shared libraries built 555 against the previous version of libc++ to crash. The incompatibility 556 has now been fixed, but any C++ applications or shared libraries built 557 between r261283 and r261801 should be recompiled. 558 55920140204: 560 OpenSSH will now ignore errors caused by kernel lacking of Capsicum 561 capability mode support. Please note that enabling the feature in 562 kernel is still highly recommended. 563 56420140131: 565 OpenSSH is now built with sandbox support, and will use sandbox as 566 the default privilege separation method. This requires Capsicum 567 capability mode support in kernel. 568 56920140128: 570 The libelf and libdwarf libraries have been updated to newer 571 versions from upstream. Shared library version numbers for 572 these two libraries were bumped. Any ports or binaries 573 requiring these two libraries should be recompiled. 574 __FreeBSD_version is bumped to 1100006. 575 57620140110: 577 If a Makefile in a tests/ directory was auto-generating a Kyuafile 578 instead of providing an explicit one, this would prevent such 579 Makefile from providing its own Kyuafile in the future during 580 NO_CLEAN builds. This has been fixed in the Makefiles but manual 581 intervention is needed to clean an objdir if you use NO_CLEAN: 582 # find /usr/obj -name Kyuafile | xargs rm -f 583 58420131213: 585 The behavior of gss_pseudo_random() for the krb5 mechanism 586 has changed, for applications requesting a longer random string 587 than produced by the underlying enctype's pseudo-random() function. 588 In particular, the random string produced from a session key of 589 enctype aes256-cts-hmac-sha1-96 or aes256-cts-hmac-sha1-96 will 590 be different at the 17th octet and later, after this change. 591 The counter used in the PRF+ construction is now encoded as a 592 big-endian integer in accordance with RFC 4402. 593 __FreeBSD_version is bumped to 1100004. 594 59520131108: 596 The WITHOUT_ATF build knob has been removed and its functionality 597 has been subsumed into the more generic WITHOUT_TESTS. If you were 598 using the former to disable the build of the ATF libraries, you 599 should change your settings to use the latter. 600 60120131025: 602 The default version of mtree is nmtree which is obtained from 603 NetBSD. The output is generally the same, but may vary 604 slightly. If you found you need identical output adding 605 "-F freebsd9" to the command line should do the trick. For the 606 time being, the old mtree is available as fmtree. 607 60820131014: 609 libbsdyml has been renamed to libyaml and moved to /usr/lib/private. 610 This will break ports-mgmt/pkg. Rebuild the port, or upgrade to pkg 611 1.1.4_8 and verify bsdyml not linked in, before running "make 612 delete-old-libs": 613 # make -C /usr/ports/ports-mgmt/pkg build deinstall install clean 614 or 615 # pkg install pkg; ldd /usr/local/sbin/pkg | grep bsdyml 616 61720131010: 618 The stable/10 branch has been created in subversion from head 619 revision r256279. 620 62120131010: 622 The rc.d/jail script has been updated to support jail(8) 623 configuration file. The "jail_<jname>_*" rc.conf(5) variables 624 for per-jail configuration are automatically converted to 625 /var/run/jail.<jname>.conf before the jail(8) utility is invoked. 626 This is transparently backward compatible. See below about some 627 incompatibilities and rc.conf(5) manual page for more details. 628 629 These variables are now deprecated in favor of jail(8) configuration 630 file. One can use "rc.d/jail config <jname>" command to generate 631 a jail(8) configuration file in /var/run/jail.<jname>.conf without 632 running the jail(8) utility. The default pathname of the 633 configuration file is /etc/jail.conf and can be specified by 634 using $jail_conf or $jail_<jname>_conf variables. 635 636 Please note that jail_devfs_ruleset accepts an integer at 637 this moment. Please consider to rewrite the ruleset name 638 with an integer. 639 64020130930: 641 BIND has been removed from the base system. If all you need 642 is a local resolver, simply enable and start the local_unbound 643 service instead. Otherwise, several versions of BIND are 644 available in the ports tree. The dns/bind99 port is one example. 645 646 With this change, nslookup(1) and dig(1) are no longer in the base 647 system. Users should instead use host(1) and drill(1) which are 648 in the base system. Alternatively, nslookup and dig can 649 be obtained by installing the dns/bind-tools port. 650 65120130916: 652 With the addition of unbound(8), a new unbound user is now 653 required during installworld. "mergemaster -p" can be used to 654 add the user prior to installworld, as documented in the handbook. 655 65620130911: 657 OpenSSH is now built with DNSSEC support, and will by default 658 silently trust signed SSHFP records. This can be controlled with 659 the VerifyHostKeyDNS client configuration setting. DNSSEC support 660 can be disabled entirely with the WITHOUT_LDNS option in src.conf. 661 66220130906: 663 The GNU Compiler Collection and C++ standard library (libstdc++) 664 are no longer built by default on platforms where clang is the system 665 compiler. You can enable them with the WITH_GCC and WITH_GNUCXX 666 options in src.conf. 667 66820130905: 669 The PROCDESC kernel option is now part of the GENERIC kernel 670 configuration and is required for the rwhod(8) to work. 671 If you are using custom kernel configuration, you should include 672 'options PROCDESC'. 673 67420130905: 675 The API and ABI related to the Capsicum framework was modified 676 in backward incompatible way. The userland libraries and programs 677 have to be recompiled to work with the new kernel. This includes the 678 following libraries and programs, but the whole buildworld is 679 advised: libc, libprocstat, dhclient, tcpdump, hastd, hastctl, 680 kdump, procstat, rwho, rwhod, uniq. 681 68220130903: 683 AES-NI intrinsic support has been added to gcc. The AES-NI module 684 has been updated to use this support. A new gcc is required to build 685 the aesni module on both i386 and amd64. 686 68720130821: 688 The PADLOCK_RNG and RDRAND_RNG kernel options are now devices. 689 Thus "device padlock_rng" and "device rdrand_rng" should be 690 used instead of "options PADLOCK_RNG" & "options RDRAND_RNG". 691 69220130813: 693 WITH_ICONV has been split into two feature sets. WITH_ICONV now 694 enables just the iconv* functionality and is now on by default. 695 WITH_LIBICONV_COMPAT enables the libiconv api and link time 696 compatability. Set WITHOUT_ICONV to build the old way. 697 If you have been using WITH_ICONV before, you will very likely 698 need to turn on WITH_LIBICONV_COMPAT. 699 70020130806: 701 INVARIANTS option now enables DEBUG for code with OpenSolaris and 702 Illumos origin, including ZFS. If you have INVARIANTS in your 703 kernel configuration, then there is no need to set DEBUG or ZFS_DEBUG 704 explicitly. 705 DEBUG used to enable witness(9) tracking of OpenSolaris (mostly ZFS) 706 locks if WITNESS option was set. Because that generated a lot of 707 witness(9) reports and all of them were believed to be false 708 positives, this is no longer done. New option OPENSOLARIS_WITNESS 709 can be used to achieve the previous behavior. 710 71120130806: 712 Timer values in IPv6 data structures now use time_uptime instead 713 of time_second. Although this is not a user-visible functional 714 change, userland utilities which directly use them---ndp(8), 715 rtadvd(8), and rtsold(8) in the base system---need to be updated 716 to r253970 or later. 717 71820130802: 719 find -delete can now delete the pathnames given as arguments, 720 instead of only files found below them or if the pathname did 721 not contain any slashes. Formerly, the following error message 722 would result: 723 724 find: -delete: <path>: relative path potentially not safe 725 726 Deleting the pathnames given as arguments can be prevented 727 without error messages using -mindepth 1 or by changing 728 directory and passing "." as argument to find. This works in the 729 old as well as the new version of find. 730 73120130726: 732 Behavior of devfs rules path matching has been changed. 733 Pattern is now always matched against fully qualified devfs 734 path and slash characters must be explicitly matched by 735 slashes in pattern (FNM_PATHNAME). Rulesets involving devfs 736 subdirectories must be reviewed. 737 73820130716: 739 The default ARM ABI has changed to the ARM EABI. The old ABI is 740 incompatible with the ARM EABI and all programs and modules will 741 need to be rebuilt to work with a new kernel. 742 743 To keep using the old ABI ensure the WITHOUT_ARM_EABI knob is set. 744 745 NOTE: Support for the old ABI will be removed in the future and 746 users are advised to upgrade. 747 74820130709: 749 pkg_install has been disconnected from the build if you really need it 750 you should add WITH_PKGTOOLS in your src.conf(5). 751 75220130709: 753 Most of network statistics structures were changed to be able 754 keep 64-bits counters. Thus all tools, that work with networking 755 statistics, must be rebuilt (netstat(1), bsnmpd(1), etc.) 756 75720130629: 758 Fix targets that run multiple make's to use && rather than ; 759 so that subsequent steps depend on success of previous. 760 761 NOTE: if building 'universe' with -j* on stable/8 or stable/9 762 it would be better to start the build using bmake, to avoid 763 overloading the machine. 764 76520130618: 766 Fix a bug that allowed a tracing process (e.g. gdb) to write 767 to a memory-mapped file in the traced process's address space 768 even if neither the traced process nor the tracing process had 769 write access to that file. 770 77120130615: 772 CVS has been removed from the base system. An exact copy 773 of the code is available from the devel/cvs port. 774 77520130613: 776 Some people report the following error after the switch to bmake: 777 778 make: illegal option -- J 779 usage: make [-BPSXeiknpqrstv] [-C directory] [-D variable] 780 ... 781 *** [buildworld] Error code 2 782 783 this likely due to an old instance of make in 784 ${MAKEPATH} (${MAKEOBJDIRPREFIX}${.CURDIR}/make.${MACHINE}) 785 which src/Makefile will use that blindly, if it exists, so if 786 you see the above error: 787 788 rm -rf `make -V MAKEPATH` 789 790 should resolve it. 791 79220130516: 793 Use bmake by default. 794 Whereas before one could choose to build with bmake via 795 -DWITH_BMAKE one must now use -DWITHOUT_BMAKE to use the old 796 make. The goal is to remove these knobs for 10-RELEASE. 797 798 It is worth noting that bmake (like gmake) treats the command 799 line as the unit of failure, rather than statements within the 800 command line. Thus '(cd some/where && dosomething)' is safer 801 than 'cd some/where; dosomething'. The '()' allows consistent 802 behavior in parallel build. 803 80420130429: 805 Fix a bug that allows NFS clients to issue READDIR on files. 806 80720130426: 808 The WITHOUT_IDEA option has been removed because 809 the IDEA patent expired. 810 81120130426: 812 The sysctl which controls TRIM support under ZFS has been renamed 813 from vfs.zfs.trim_disable -> vfs.zfs.trim.enabled and has been 814 enabled by default. 815 81620130425: 817 The mergemaster command now uses the default MAKEOBJDIRPREFIX 818 rather than creating it's own in the temporary directory in 819 order allow access to bootstrapped versions of tools such as 820 install and mtree. When upgrading from version of FreeBSD where 821 the install command does not support -l, you will need to 822 install a new mergemaster command if mergemaster -p is required. 823 This can be accomplished with the command (cd src/usr.sbin/mergemaster 824 && make install). 825 82620130404: 827 Legacy ATA stack, disabled and replaced by new CAM-based one since 828 FreeBSD 9.0, completely removed from the sources. Kernel modules 829 atadisk and atapi*, user-level tools atacontrol and burncd are 830 removed. Kernel option `options ATA_CAM` is now permanently enabled 831 and removed. 832 83320130319: 834 SOCK_CLOEXEC and SOCK_NONBLOCK flags have been added to socket(2) 835 and socketpair(2). Software, in particular Kerberos, may 836 automatically detect and use these during building. The resulting 837 binaries will not work on older kernels. 838 83920130308: 840 CTL_DISABLE has also been added to the sparc64 GENERIC (for further 841 information, see the respective 20130304 entry). 842 84320130304: 844 Recent commits to callout(9) changed the size of struct callout, 845 so the KBI is probably heavily disturbed. Also, some functions 846 in callout(9)/sleep(9)/sleepqueue(9)/condvar(9) KPIs were replaced 847 by macros. Every kernel module using it won't load, so rebuild 848 is requested. 849 850 The ctl device has been re-enabled in GENERIC for i386 and amd64, 851 but does not initialize by default (because of the new CTL_DISABLE 852 option) to save memory. To re-enable it, remove the CTL_DISABLE 853 option from the kernel config file or set kern.cam.ctl.disable=0 854 in /boot/loader.conf. 855 85620130301: 857 The ctl device has been disabled in GENERIC for i386 and amd64. 858 This was done due to the extra memory being allocated at system 859 initialisation time by the ctl driver which was only used if 860 a CAM target device was created. This makes a FreeBSD system 861 unusable on 128MB or less of RAM. 862 86320130208: 864 A new compression method (lz4) has been merged to -HEAD. Please 865 refer to zpool-features(7) for more information. 866 867 Please refer to the "ZFS notes" section of this file for information 868 on upgrading boot ZFS pools. 869 87020130129: 871 A BSD-licensed patch(1) variant has been added and is installed 872 as bsdpatch, being the GNU version the default patch. 873 To inverse the logic and use the BSD-licensed one as default, 874 while having the GNU version installed as gnupatch, rebuild 875 and install world with the WITH_BSD_PATCH knob set. 876 87720130121: 878 Due to the use of the new -l option to install(1) during build 879 and install, you must take care not to directly set the INSTALL 880 make variable in your /etc/make.conf, /etc/src.conf, or on the 881 command line. If you wish to use the -C flag for all installs 882 you may be able to add INSTALL+=-C to /etc/make.conf or 883 /etc/src.conf. 884 88520130118: 886 The install(1) option -M has changed meaning and now takes an 887 argument that is a file or path to append logs to. In the 888 unlikely event that -M was the last option on the command line 889 and the command line contained at least two files and a target 890 directory the first file will have logs appended to it. The -M 891 option served little practical purpose in the last decade so its 892 use is expected to be extremely rare. 893 89420121223: 895 After switching to Clang as the default compiler some users of ZFS 896 on i386 systems started to experience stack overflow kernel panics. 897 Please consider using 'options KSTACK_PAGES=4' in such configurations. 898 89920121222: 900 GEOM_LABEL now mangles label names read from file system metadata. 901 Mangling affect labels containing spaces, non-printable characters, 902 '%' or '"'. Device names in /etc/fstab and other places may need to 903 be updated. 904 90520121217: 906 By default, only the 10 most recent kernel dumps will be saved. To 907 restore the previous behaviour (no limit on the number of kernel dumps 908 stored in the dump directory) add the following line to /etc/rc.conf: 909 910 savecore_flags="" 911 91220121201: 913 With the addition of auditdistd(8), a new auditdistd user is now 914 required during installworld. "mergemaster -p" can be used to 915 add the user prior to installworld, as documented in the handbook. 916 91720121117: 918 The sin6_scope_id member variable in struct sockaddr_in6 is now 919 filled by the kernel before passing the structure to the userland via 920 sysctl or routing socket. This means the KAME-specific embedded scope 921 id in sin6_addr.s6_addr[2] is always cleared in userland application. 922 This behavior can be controlled by net.inet6.ip6.deembed_scopeid. 923 __FreeBSD_version is bumped to 1000025. 924 92520121105: 926 On i386 and amd64 systems WITH_CLANG_IS_CC is now the default. 927 This means that the world and kernel will be compiled with clang 928 and that clang will be installed as /usr/bin/cc, /usr/bin/c++, 929 and /usr/bin/cpp. To disable this behavior and revert to building 930 with gcc, compile with WITHOUT_CLANG_IS_CC. Really old versions 931 of current may need to bootstrap WITHOUT_CLANG first if the clang 932 build fails (its compatibility window doesn't extend to the 9 stable 933 branch point). 934 93520121102: 936 The IPFIREWALL_FORWARD kernel option has been removed. Its 937 functionality now turned on by default. 938 93920121023: 940 The ZERO_COPY_SOCKET kernel option has been removed and 941 split into SOCKET_SEND_COW and SOCKET_RECV_PFLIP. 942 NB: SOCKET_SEND_COW uses the VM page based copy-on-write 943 mechanism which is not safe and may result in kernel crashes. 944 NB: The SOCKET_RECV_PFLIP mechanism is useless as no current 945 driver supports disposeable external page sized mbuf storage. 946 Proper replacements for both zero-copy mechanisms are under 947 consideration and will eventually lead to complete removal 948 of the two kernel options. 949 95020121023: 951 The IPv4 network stack has been converted to network byte 952 order. The following modules need to be recompiled together 953 with kernel: carp(4), divert(4), gif(4), siftr(4), gre(4), 954 pf(4), ipfw(4), ng_ipfw(4), stf(4). 955 95620121022: 957 Support for non-MPSAFE filesystems was removed from VFS. The 958 VFS_VERSION was bumped, all filesystem modules shall be 959 recompiled. 960 96120121018: 962 All the non-MPSAFE filesystems have been disconnected from 963 the build. The full list includes: codafs, hpfs, ntfs, nwfs, 964 portalfs, smbfs, xfs. 965 96620121016: 967 The interface cloning API and ABI has changed. The following 968 modules need to be recompiled together with kernel: 969 ipfw(4), pfsync(4), pflog(4), usb(4), wlan(4), stf(4), 970 vlan(4), disc(4), edsc(4), if_bridge(4), gif(4), tap(4), 971 faith(4), epair(4), enc(4), tun(4), if_lagg(4), gre(4). 972 97320121015: 974 The sdhci driver was split in two parts: sdhci (generic SD Host 975 Controller logic) and sdhci_pci (actual hardware driver). 976 No kernel config modifications are required, but if you 977 load sdhc as a module you must switch to sdhci_pci instead. 978 97920121014: 980 Import the FUSE kernel and userland support into base system. 981 98220121013: 983 The GNU sort(1) program has been removed since the BSD-licensed 984 sort(1) has been the default for quite some time and no serious 985 problems have been reported. The corresponding WITH_GNU_SORT 986 knob has also gone. 987 98820121006: 989 The pfil(9) API/ABI for AF_INET family has been changed. Packet 990 filtering modules: pf(4), ipfw(4), ipfilter(4) need to be recompiled 991 with new kernel. 992 99320121001: 994 The net80211(4) ABI has been changed to allow for improved driver 995 PS-POLL and power-save support. All wireless drivers need to be 996 recompiled to work with the new kernel. 997 99820120913: 999 The random(4) support for the VIA hardware random number 1000 generator (`PADLOCK') is no longer enabled unconditionally. 1001 Add the padlock_rng device in the custom kernel config if 1002 needed. The GENERIC kernels on i386 and amd64 do include the 1003 device, so the change only affects the custom kernel 1004 configurations. 1005 100620120908: 1007 The pf(4) packet filter ABI has been changed. pfctl(8) and 1008 snmp_pf module need to be recompiled to work with new kernel. 1009 101020120828: 1011 A new ZFS feature flag "com.delphix:empty_bpobj" has been merged 1012 to -HEAD. Pools that have empty_bpobj in active state can not be 1013 imported read-write with ZFS implementations that do not support 1014 this feature. For more information read the zpool-features(5) 1015 manual page. 1016 101720120727: 1018 The sparc64 ZFS loader has been changed to no longer try to auto- 1019 detect ZFS providers based on diskN aliases but now requires these 1020 to be explicitly listed in the OFW boot-device environment variable. 1021 102220120712: 1023 The OpenSSL has been upgraded to 1.0.1c. Any binaries requiring 1024 libcrypto.so.6 or libssl.so.6 must be recompiled. Also, there are 1025 configuration changes. Make sure to merge /etc/ssl/openssl.cnf. 1026 102720120712: 1028 The following sysctls and tunables have been renamed for consistency 1029 with other variables: 1030 kern.cam.da.da_send_ordered -> kern.cam.da.send_ordered 1031 kern.cam.ada.ada_send_ordered -> kern.cam.ada.send_ordered 1032 103320120628: 1034 The sort utility has been replaced with BSD sort. For now, GNU sort 1035 is also available as "gnusort" or the default can be set back to 1036 GNU sort by setting WITH_GNU_SORT. In this case, BSD sort will be 1037 installed as "bsdsort". 1038 103920120611: 1040 A new version of ZFS (pool version 5000) has been merged to -HEAD. 1041 Starting with this version the old system of ZFS pool versioning 1042 is superseded by "feature flags". This concept enables forward 1043 compatibility against certain future changes in functionality of ZFS 1044 pools. The first read-only compatible "feature flag" for ZFS pools 1045 is named "com.delphix:async_destroy". For more information 1046 read the new zpool-features(5) manual page. 1047 Please refer to the "ZFS notes" section of this file for information 1048 on upgrading boot ZFS pools. 1049 105020120417: 1051 The malloc(3) implementation embedded in libc now uses sources imported 1052 as contrib/jemalloc. The most disruptive API change is to 1053 /etc/malloc.conf. If your system has an old-style /etc/malloc.conf, 1054 delete it prior to installworld, and optionally re-create it using the 1055 new format after rebooting. See malloc.conf(5) for details 1056 (specifically the TUNING section and the "opt.*" entries in the MALLCTL 1057 NAMESPACE section). 1058 105920120328: 1060 Big-endian MIPS TARGET_ARCH values no longer end in "eb". mips64eb 1061 is now spelled mips64. mipsn32eb is now spelled mipsn32. mipseb is 1062 now spelled mips. This is to aid compatibility with third-party 1063 software that expects this naming scheme in uname(3). Little-endian 1064 settings are unchanged. If you are updating a big-endian mips64 machine 1065 from before this change, you may need to set MACHINE_ARCH=mips64 in 1066 your environment before the new build system will recognize your machine. 1067 106820120306: 1069 Disable by default the option VFS_ALLOW_NONMPSAFE for all supported 1070 platforms. 1071 107220120229: 1073 Now unix domain sockets behave "as expected" on nullfs(5). Previously 1074 nullfs(5) did not pass through all behaviours to the underlying layer, 1075 as a result if we bound to a socket on the lower layer we could connect 1076 only to the lower path; if we bound to the upper layer we could connect 1077 only to the upper path. The new behavior is one can connect to both the 1078 lower and the upper paths regardless what layer path one binds to. 1079 108020120211: 1081 The getifaddrs upgrade path broken with 20111215 has been restored. 1082 If you have upgraded in between 20111215 and 20120209 you need to 1083 recompile libc again with your kernel. You still need to recompile 1084 world to be able to configure CARP but this restriction already 1085 comes from 20111215. 1086 108720120114: 1088 The set_rcvar() function has been removed from /etc/rc.subr. All 1089 base and ports rc.d scripts have been updated, so if you have a 1090 port installed with a script in /usr/local/etc/rc.d you can either 1091 hand-edit the rcvar= line, or reinstall the port. 1092 1093 An easy way to handle the mass-update of /etc/rc.d: 1094 rm /etc/rc.d/* && mergemaster -i 1095 109620120109: 1097 panic(9) now stops other CPUs in the SMP systems, disables interrupts 1098 on the current CPU and prevents other threads from running. 1099 This behavior can be reverted using the kern.stop_scheduler_on_panic 1100 tunable/sysctl. 1101 The new behavior can be incompatible with kern.sync_on_panic. 1102 110320111215: 1104 The carp(4) facility has been changed significantly. Configuration 1105 of the CARP protocol via ifconfig(8) has changed, as well as format 1106 of CARP events submitted to devd(8) has changed. See manual pages 1107 for more information. The arpbalance feature of carp(4) is currently 1108 not supported anymore. 1109 1110 Size of struct in_aliasreq, struct in6_aliasreq has changed. User 1111 utilities using SIOCAIFADDR, SIOCAIFADDR_IN6, e.g. ifconfig(8), 1112 need to be recompiled. 1113 111420111122: 1115 The acpi_wmi(4) status device /dev/wmistat has been renamed to 1116 /dev/wmistat0. 1117 111820111108: 1119 The option VFS_ALLOW_NONMPSAFE option has been added in order to 1120 explicitely support non-MPSAFE filesystems. 1121 It is on by default for all supported platform at this present 1122 time. 1123 112420111101: 1125 The broken amd(4) driver has been replaced with esp(4) in the amd64, 1126 i386 and pc98 GENERIC kernel configuration files. 1127 112820110930: 1129 sysinstall has been removed 1130 113120110923: 1132 The stable/9 branch created in subversion. This corresponds to the 1133 RELENG_9 branch in CVS. 1134 1135COMMON ITEMS: 1136 1137 General Notes 1138 ------------- 1139 Avoid using make -j when upgrading. While generally safe, there are 1140 sometimes problems using -j to upgrade. If your upgrade fails with 1141 -j, please try again without -j. From time to time in the past there 1142 have been problems using -j with buildworld and/or installworld. This 1143 is especially true when upgrading between "distant" versions (eg one 1144 that cross a major release boundary or several minor releases, or when 1145 several months have passed on the -current branch). 1146 1147 Sometimes, obscure build problems are the result of environment 1148 poisoning. This can happen because the make utility reads its 1149 environment when searching for values for global variables. To run 1150 your build attempts in an "environmental clean room", prefix all make 1151 commands with 'env -i '. See the env(1) manual page for more details. 1152 1153 When upgrading from one major version to another it is generally best 1154 to upgrade to the latest code in the currently installed branch first, 1155 then do an upgrade to the new branch. This is the best-tested upgrade 1156 path, and has the highest probability of being successful. Please try 1157 this approach before reporting problems with a major version upgrade. 1158 1159 When upgrading a live system, having a root shell around before 1160 installing anything can help undo problems. Not having a root shell 1161 around can lead to problems if pam has changed too much from your 1162 starting point to allow continued authentication after the upgrade. 1163 1164 This file should be read as a log of events. When a later event changes 1165 information of a prior event, the prior event should not be deleted. 1166 Instead, a pointer to the entry with the new information should be 1167 placed in the old entry. Readers of this file should also sanity check 1168 older entries before relying on them blindly. Authors of new entries 1169 should write them with this in mind. 1170 1171 ZFS notes 1172 --------- 1173 When upgrading the boot ZFS pool to a new version, always follow 1174 these two steps: 1175 1176 1.) recompile and reinstall the ZFS boot loader and boot block 1177 (this is part of "make buildworld" and "make installworld") 1178 1179 2.) update the ZFS boot block on your boot drive 1180 1181 The following example updates the ZFS boot block on the first 1182 partition (freebsd-boot) of a GPT partitioned drive ada0: 1183 "gpart bootcode -p /boot/gptzfsboot -i 1 ada0" 1184 1185 Non-boot pools do not need these updates. 1186 1187 To build a kernel 1188 ----------------- 1189 If you are updating from a prior version of FreeBSD (even one just 1190 a few days old), you should follow this procedure. It is the most 1191 failsafe as it uses a /usr/obj tree with a fresh mini-buildworld, 1192 1193 make kernel-toolchain 1194 make -DALWAYS_CHECK_MAKE buildkernel KERNCONF=YOUR_KERNEL_HERE 1195 make -DALWAYS_CHECK_MAKE installkernel KERNCONF=YOUR_KERNEL_HERE 1196 1197 To test a kernel once 1198 --------------------- 1199 If you just want to boot a kernel once (because you are not sure 1200 if it works, or if you want to boot a known bad kernel to provide 1201 debugging information) run 1202 make installkernel KERNCONF=YOUR_KERNEL_HERE KODIR=/boot/testkernel 1203 nextboot -k testkernel 1204 1205 To just build a kernel when you know that it won't mess you up 1206 -------------------------------------------------------------- 1207 This assumes you are already running a CURRENT system. Replace 1208 ${arch} with the architecture of your machine (e.g. "i386", 1209 "arm", "amd64", "ia64", "pc98", "sparc64", "powerpc", "mips", etc). 1210 1211 cd src/sys/${arch}/conf 1212 config KERNEL_NAME_HERE 1213 cd ../compile/KERNEL_NAME_HERE 1214 make depend 1215 make 1216 make install 1217 1218 If this fails, go to the "To build a kernel" section. 1219 1220 To rebuild everything and install it on the current system. 1221 ----------------------------------------------------------- 1222 # Note: sometimes if you are running current you gotta do more than 1223 # is listed here if you are upgrading from a really old current. 1224 1225 <make sure you have good level 0 dumps> 1226 make buildworld 1227 make kernel KERNCONF=YOUR_KERNEL_HERE 1228 [1] 1229 <reboot in single user> [3] 1230 mergemaster -Fp [5] 1231 make installworld 1232 mergemaster -Fi [4] 1233 make delete-old [6] 1234 <reboot> 1235 1236 To cross-install current onto a separate partition 1237 -------------------------------------------------- 1238 # In this approach we use a separate partition to hold 1239 # current's root, 'usr', and 'var' directories. A partition 1240 # holding "/", "/usr" and "/var" should be about 2GB in 1241 # size. 1242 1243 <make sure you have good level 0 dumps> 1244 <boot into -stable> 1245 make buildworld 1246 make buildkernel KERNCONF=YOUR_KERNEL_HERE 1247 <maybe newfs current's root partition> 1248 <mount current's root partition on directory ${CURRENT_ROOT}> 1249 make installworld DESTDIR=${CURRENT_ROOT} -DDB_FROM_SRC 1250 make distribution DESTDIR=${CURRENT_ROOT} # if newfs'd 1251 make installkernel KERNCONF=YOUR_KERNEL_HERE DESTDIR=${CURRENT_ROOT} 1252 cp /etc/fstab ${CURRENT_ROOT}/etc/fstab # if newfs'd 1253 <edit ${CURRENT_ROOT}/etc/fstab to mount "/" from the correct partition> 1254 <reboot into current> 1255 <do a "native" rebuild/install as described in the previous section> 1256 <maybe install compatibility libraries from ports/misc/compat*> 1257 <reboot> 1258 1259 1260 To upgrade in-place from stable to current 1261 ---------------------------------------------- 1262 <make sure you have good level 0 dumps> 1263 make buildworld [9] 1264 make kernel KERNCONF=YOUR_KERNEL_HERE [8] 1265 [1] 1266 <reboot in single user> [3] 1267 mergemaster -Fp [5] 1268 make installworld 1269 mergemaster -Fi [4] 1270 make delete-old [6] 1271 <reboot> 1272 1273 Make sure that you've read the UPDATING file to understand the 1274 tweaks to various things you need. At this point in the life 1275 cycle of current, things change often and you are on your own 1276 to cope. The defaults can also change, so please read ALL of 1277 the UPDATING entries. 1278 1279 Also, if you are tracking -current, you must be subscribed to 1280 freebsd-current@freebsd.org. Make sure that before you update 1281 your sources that you have read and understood all the recent 1282 messages there. If in doubt, please track -stable which has 1283 much fewer pitfalls. 1284 1285 [1] If you have third party modules, such as vmware, you 1286 should disable them at this point so they don't crash your 1287 system on reboot. 1288 1289 [3] From the bootblocks, boot -s, and then do 1290 fsck -p 1291 mount -u / 1292 mount -a 1293 cd src 1294 adjkerntz -i # if CMOS is wall time 1295 Also, when doing a major release upgrade, it is required that 1296 you boot into single user mode to do the installworld. 1297 1298 [4] Note: This step is non-optional. Failure to do this step 1299 can result in a significant reduction in the functionality of the 1300 system. Attempting to do it by hand is not recommended and those 1301 that pursue this avenue should read this file carefully, as well 1302 as the archives of freebsd-current and freebsd-hackers mailing lists 1303 for potential gotchas. The -U option is also useful to consider. 1304 See mergemaster(8) for more information. 1305 1306 [5] Usually this step is a noop. However, from time to time 1307 you may need to do this if you get unknown user in the following 1308 step. It never hurts to do it all the time. You may need to 1309 install a new mergemaster (cd src/usr.sbin/mergemaster && make 1310 install) after the buildworld before this step if you last updated 1311 from current before 20130425 or from -stable before 20130430. 1312 1313 [6] This only deletes old files and directories. Old libraries 1314 can be deleted by "make delete-old-libs", but you have to make 1315 sure that no program is using those libraries anymore. 1316 1317 [8] In order to have a kernel that can run the 4.x binaries needed to 1318 do an installworld, you must include the COMPAT_FREEBSD4 option in 1319 your kernel. Failure to do so may leave you with a system that is 1320 hard to boot to recover. A similar kernel option COMPAT_FREEBSD5 is 1321 required to run the 5.x binaries on more recent kernels. And so on 1322 for COMPAT_FREEBSD6 and COMPAT_FREEBSD7. 1323 1324 Make sure that you merge any new devices from GENERIC since the 1325 last time you updated your kernel config file. 1326 1327 [9] When checking out sources, you must include the -P flag to have 1328 cvs prune empty directories. 1329 1330 If CPUTYPE is defined in your /etc/make.conf, make sure to use the 1331 "?=" instead of the "=" assignment operator, so that buildworld can 1332 override the CPUTYPE if it needs to. 1333 1334 MAKEOBJDIRPREFIX must be defined in an environment variable, and 1335 not on the command line, or in /etc/make.conf. buildworld will 1336 warn if it is improperly defined. 1337FORMAT: 1338 1339This file contains a list, in reverse chronological order, of major 1340breakages in tracking -current. It is not guaranteed to be a complete 1341list of such breakages, and only contains entries since September 23, 2011. 1342If you need to see UPDATING entries from before that date, you will need 1343to fetch an UPDATING file from an older FreeBSD release. 1344 1345Copyright information: 1346 1347Copyright 1998-2009 M.
