UPDATING revision 289445
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 17from older 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 3420151012: 35 If you specify SENDMAIL_MC or SENDMAIL_CF in make.conf, mergemaster 36 and etcupdate will now use this file. A custom sendmail.cf is now 37 updated via this mechanism rather than via installworld. If you had 38 excluded sendmail.cf in mergemaster.rc or etcupdate.conf, you may 39 want to remove the exclusion or change it to "always install". 40 /etc/mail/sendmail.cf is now managed the same way regardless of 41 whether SENDMAIL_MC/SENDMAIL_CF is used. If you are not using 42 SENDMAIL_MC/SENDMAIL_CF there should be no change in behavior. 43 4420151011: 45 Compatibility shims for legacy ATA device names have been removed. 46 It includes ATA_STATIC_ID kernel option, kern.cam.ada.legacy_aliases 47 and kern.geom.raid.legacy_aliases loader tunables, kern.devalias.* 48 environment variables, /dev/ad* and /dev/ar* symbolic links. 49 5020151006: 51 Clang, llvm, lldb, compiler-rt and libc++ have been upgraded to 3.7.0. 52 Please see the 20141231 entry below for information about prerequisites 53 and upgrading, if you are not already using clang 3.5.0 or higher. 54 5520150924: 56 Kernel debug files have been moved to /usr/lib/debug/boot/kernel/, 57 and renamed from .symbols to .debug. This reduces the size requirements 58 on the boot partition or file system and provides consistency with 59 userland debug files. 60 61 When using the supported kernel installation method the 62 /usr/lib/debug/boot/kernel directory will be renamed (to kernel.old) 63 as is done with /boot/kernel. 64 65 Developers wishing to maintain the historical behavior of installing 66 debug files in /boot/kernel/ can set KERN_DEBUGDIR="" in src.conf(5). 67 6820150827: 69 The wireless drivers had undergone changes that remove the 'parent 70 interface' from the ifconfig -l output. The rc.d network scripts 71 used to check presence of a parent interface in the list, so old 72 scripts would fail to start wireless networking. Thus, etcupdate(3) 73 or mergemaster(8) run is required after kernel update, to update your 74 rc.d scripts in /etc. 75 7620150827: 77 pf no longer supports 'scrub fragment crop' or 'scrub fragment drop-ovl' 78 These configurations are now automatically interpreted as 79 'scrub fragment reassemble'. 80 8120150817: 82 Kernel-loadable modules for the random(4) device are back. To use 83 them, the kernel must have 84 85 device random 86 options RANDOM_LOADABLE 87 88 kldload(8) can then be used to load random_fortuna.ko 89 or random_yarrow.ko. Please note that due to the indirect 90 function calls that the loadable modules need to provide, 91 the build-in variants will be slightly more efficient. 92 93 The random(4) kernel option RANDOM_DUMMY has been retired due to 94 unpopularity. It was not all that useful anyway. 95 9620150813: 97 The WITHOUT_ELFTOOLCHAIN_TOOLS src.conf(5) knob has been retired. 98 Control over building the ELF Tool Chain tools is now provided by 99 the WITHOUT_TOOLCHAIN knob. 100 10120150810: 102 The polarity of Pulse Per Second (PPS) capture events with the 103 uart(4) driver has been corrected. Prior to this change the PPS 104 "assert" event corresponded to the trailing edge of a positive PPS 105 pulse and the "clear" event was the leading edge of the next pulse. 106 107 As the width of a PPS pulse in a typical GPS receiver is on the 108 order of 1 millisecond, most users will not notice any significant 109 difference with this change. 110 111 Anyone who has compensated for the historical polarity reversal by 112 configuring a negative offset equal to the pulse width will need to 113 remove that workaround. 114 11520150809: 116 The default group assigned to /dev/dri entries has been changed 117 from 'wheel' to 'video' with the id of '44'. If you want to have 118 access to the dri devices please add yourself to the video group 119 with: 120 121 # pw groupmod video -m $USER 122 12320150806: 124 The menu.rc and loader.rc files will now be replaced during 125 upgrades. Please migrate local changes to menu.rc.local and 126 loader.rc.local instead. 127 12820150805: 129 GNU Binutils versions of addr2line, c++filt, nm, readelf, size, 130 strings and strip have been removed. The src.conf(5) knob 131 WITHOUT_ELFTOOLCHAIN_TOOLS no longer provides the binutils tools. 132 13320150728: 134 As ZFS requires more kernel stack pages than is the default on some 135 architectures e.g. i386, it now warns if KSTACK_PAGES is less than 136 ZFS_MIN_KSTACK_PAGES (which is 4 at the time of writing). 137 138 Please consider using 'options KSTACK_PAGES=X' where X is greater 139 than or equal to ZFS_MIN_KSTACK_PAGES i.e. 4 in such configurations. 140 14120150706: 142 sendmail has been updated to 8.15.2. Starting with FreeBSD 11.0 143 and sendmail 8.15, sendmail uses uncompressed IPv6 addresses by 144 default, i.e., they will not contain "::". For example, instead 145 of ::1, it will be 0:0:0:0:0:0:0:1. This permits a zero subnet 146 to have a more specific match, such as different map entries for 147 IPv6:0:0 vs IPv6:0. This change requires that configuration 148 data (including maps, files, classes, custom ruleset, etc.) must 149 use the same format, so make certain such configuration data is 150 upgrading. As a very simple check search for patterns like 151 'IPv6:[0-9a-fA-F:]*::' and 'IPv6::'. To return to the old 152 behavior, set the m4 option confUSE_COMPRESSED_IPV6_ADDRESSES or 153 the cf option UseCompressedIPv6Addresses. 154 15520150630: 156 The default kernel entropy-processing algorithm is now 157 Fortuna, replacing Yarrow. 158 159 Assuming you have 'device random' in your kernel config 160 file, the configurations allow a kernel option to override 161 this default. You may choose *ONE* of: 162 163 options RANDOM_YARROW # Legacy /dev/random algorithm. 164 options RANDOM_DUMMY # Blocking-only driver. 165 166 If you have neither, you get Fortuna. For most people, 167 read no further, Fortuna will give a /dev/random that works 168 like it always used to, and the difference will be irrelevant. 169 170 If you remove 'device random', you get *NO* kernel-processed 171 entopy at all. This may be acceptable to folks building 172 embedded systems, but has complications. Carry on reading, 173 and it is assumed you know what you need. 174 175 *PLEASE* read random(4) and random(9) if you are in the 176 habit of tweeking kernel configs, and/or if you are a member 177 of the embedded community, wanting specific and not-usual 178 behaviour from your security subsystems. 179 180 NOTE!! If you use RANDOM_DUMMY and/or have no 'device 181 random', you will NOT have a functioning /dev/random, and 182 many cryptographic features will not work, including SSH. 183 You may also find strange behaviour from the random(3) set 184 of library functions, in particular sranddev(3), srandomdev(3) 185 and arc4random(3). The reason for this is that the KERN_ARND 186 sysctl only returns entropy if it thinks it has some to 187 share, and with RANDOM_DUMMY or no 'device random' this 188 will never happen. 189 19020150623: 191 An additional fix for the issue described in the 20150614 sendmail 192 entry below has been been committed in revision 284717. 193 19420150616: 195 FreeBSD's old make (fmake) has been removed from the system. It is 196 available as the devel/fmake port or via pkg install fmake. 197 19820150615: 199 The fix for the issue described in the 20150614 sendmail entry 200 below has been been committed in revision 284436. The work 201 around described in that entry is no longer needed unless the 202 default setting is overridden by a confDH_PARAMETERS configuration 203 setting of '5' or pointing to a 512 bit DH parameter file. 204 20520150614: 206 ALLOW_DEPRECATED_ATF_TOOLS/ATFFILE support has been removed from 207 atf.test.mk (included from bsd.test.mk). Please upgrade devel/atf 208 and devel/kyua to version 0.20+ and adjust any calling code to work 209 with Kyuafile and kyua. 210 21120150614: 212 The import of openssl to address the FreeBSD-SA-15:10.openssl 213 security advisory includes a change which rejects handshakes 214 with DH parameters below 768 bits. sendmail releases prior 215 to 8.15.2 (not yet released), defaulted to a 512 bit 216 DH parameter setting for client connections. To work around 217 this interoperability, sendmail can be configured to use a 218 2048 bit DH parameter by: 219 220 1. Edit /etc/mail/`hostname`.mc 221 2. If a setting for confDH_PARAMETERS does not exist or 222 exists and is set to a string beginning with '5', 223 replace it with '2'. 224 3. If a setting for confDH_PARAMETERS exists and is set to 225 a file path, create a new file with: 226 openssl dhparam -out /path/to/file 2048 227 4. Rebuild the .cf file: 228 cd /etc/mail/; make; make install 229 5. Restart sendmail: 230 cd /etc/mail/; make restart 231 232 A sendmail patch is coming, at which time this file will be 233 updated. 234 23520150604: 236 Generation of legacy formatted entries have been disabled by default 237 in pwd_mkdb(8), as all base system consumers of the legacy formatted 238 entries were converted to use the new format by default when the new, 239 machine independent format have been added and supported since FreeBSD 240 5.x. 241 242 Please see the pwd_mkdb(8) manual page for further details. 243 24420150525: 245 Clang and llvm have been upgraded to 3.6.1 release. Please see the 246 20141231 entry below for information about prerequisites and upgrading, 247 if you are not already using 3.5.0 or higher. 248 24920150521: 250 TI platform code switched to using vendor DTS files and this update 251 may break existing systems running on Beaglebone, Beaglebone Black, 252 and Pandaboard: 253 254 - dtb files should be regenerated/reinstalled. Filenames are the 255 same but content is different now 256 - GPIO addressing was changed, now each GPIO bank (32 pins per bank) 257 has its own /dev/gpiocX device, e.g. pin 121 on /dev/gpioc0 in old 258 addressing scheme is now pin 25 on /dev/gpioc3. 259 - Pandaboard: /etc/ttys should be updated, serial console device is 260 now /dev/ttyu2, not /dev/ttyu0 261 26220150501: 263 soelim(1) from gnu/usr.bin/groff has been replaced by usr.bin/soelim. 264 If you need the GNU extension from groff soelim(1), install groff 265 from package: pkg install groff, or via ports: textproc/groff. 266 26720150423: 268 chmod, chflags, chown and chgrp now affect symlinks in -R mode as 269 defined in symlink(7); previously symlinks were silently ignored. 270 27120150415: 272 The const qualifier has been removed from iconv(3) to comply with 273 POSIX. The ports tree is aware of this from r384038 onwards. 274 27520150416: 276 Libraries specified by LIBADD in Makefiles must have a corresponding 277 DPADD_<lib> variable to ensure correct dependencies. This is now 278 enforced in src.libnames.mk. 279 28020150324: 281 From legacy ata(4) driver was removed support for SATA controllers 282 supported by more functional drivers ahci(4), siis(4) and mvs(4). 283 Kernel modules ataahci and ataadaptec were removed completely, 284 replaced by ahci and mvs modules respectively. 285 28620150315: 287 Clang, llvm and lldb have been upgraded to 3.6.0 release. Please see 288 the 20141231 entry below for information about prerequisites and 289 upgrading, if you are not already using 3.5.0 or higher. 290 29120150307: 292 The 32-bit PowerPC kernel has been changed to a position-independent 293 executable. This can only be booted with a version of loader(8) 294 newer than January 31, 2015, so make sure to update both world and 295 kernel before rebooting. 296 29720150217: 298 If you are running a -CURRENT kernel since r273872 (Oct 30th, 2014), 299 but before r278950, the RNG was not seeded properly. Immediately 300 upgrade the kernel to r278950 or later and regenerate any keys (e.g. 301 ssh keys or openssl keys) that were generated w/ a kernel from that 302 range. This does not affect programs that directly used /dev/random 303 or /dev/urandom. All userland uses of arc4random(3) are affected. 304 30520150210: 306 The autofs(4) ABI was changed in order to restore binary compatibility 307 with 10.1-RELEASE. The automountd(8) daemon needs to be rebuilt to work 308 with the new kernel. 309 31020150131: 311 The powerpc64 kernel has been changed to a position-independent 312 executable. This can only be booted with a new version of loader(8), 313 so make sure to update both world and kernel before rebooting. 314 31520150118: 316 Clang and llvm have been upgraded to 3.5.1 release. This is a bugfix 317 only release, no new features have been added. Please see the 20141231 318 entry below for information about prerequisites and upgrading, if you 319 are not already using 3.5.0. 320 32120150107: 322 ELF tools addr2line, elfcopy (strip), nm, size, and strings are now 323 taken from the ELF Tool Chain project rather than GNU binutils. They 324 should be drop-in replacements, with the addition of arm64 support. 325 The WITHOUT_ELFTOOLCHAIN_TOOLS= knob may be used to obtain the 326 binutils tools, if necessary. See 20150805 for updated information. 327 32820150105: 329 The default Unbound configuration now enables remote control 330 using a local socket. Users who have already enabled the 331 local_unbound service should regenerate their configuration 332 by running "service local_unbound setup" as root. 333 33420150102: 335 The GNU texinfo and GNU info pages have been removed. 336 To be able to view GNU info pages please install texinfo from ports. 337 33820141231: 339 Clang, llvm and lldb have been upgraded to 3.5.0 release. 340 341 As of this release, a prerequisite for building clang, llvm and lldb is 342 a C++11 capable compiler and C++11 standard library. This means that to 343 be able to successfully build the cross-tools stage of buildworld, with 344 clang as the bootstrap compiler, your system compiler or cross compiler 345 should either be clang 3.3 or later, or gcc 4.8 or later, and your 346 system C++ library should be libc++, or libdstdc++ from gcc 4.8 or 347 later. 348 349 On any standard FreeBSD 10.x or 11.x installation, where clang and 350 libc++ are on by default (that is, on x86 or arm), this should work out 351 of the box. 352 353 On 9.x installations where clang is enabled by default, e.g. on x86 and 354 powerpc, libc++ will not be enabled by default, so libc++ should be 355 built (with clang) and installed first. If both clang and libc++ are 356 missing, build clang first, then use it to build libc++. 357 358 On 8.x and earlier installations, upgrade to 9.x first, and then follow 359 the instructions for 9.x above. 360 361 Sparc64 and mips users are unaffected, as they still use gcc 4.2.1 by 362 default, and do not build clang. 363 364 Many embedded systems are resource constrained, and will not be able to 365 build clang in a reasonable time, or in some cases at all. In those 366 cases, cross building bootable systems on amd64 is a workaround. 367 368 This new version of clang introduces a number of new warnings, of which 369 the following are most likely to appear: 370 371 -Wabsolute-value 372 373 This warns in two cases, for both C and C++: 374 * When the code is trying to take the absolute value of an unsigned 375 quantity, which is effectively a no-op, and almost never what was 376 intended. The code should be fixed, if at all possible. If you are 377 sure that the unsigned quantity can be safely cast to signed, without 378 loss of information or undefined behavior, you can add an explicit 379 cast, or disable the warning. 380 381 * When the code is trying to take an absolute value, but the called 382 abs() variant is for the wrong type, which can lead to truncation. 383 If you want to disable the warning instead of fixing the code, please 384 make sure that truncation will not occur, or it might lead to unwanted 385 side-effects. 386 387 -Wtautological-undefined-compare and 388 -Wundefined-bool-conversion 389 390 These warn when C++ code is trying to compare 'this' against NULL, while 391 'this' should never be NULL in well-defined C++ code. However, there is 392 some legacy (pre C++11) code out there, which actively abuses this 393 feature, which was less strictly defined in previous C++ versions. 394 395 Squid and openjdk do this, for example. The warning can be turned off 396 for C++98 and earlier, but compiling the code in C++11 mode might result 397 in unexpected behavior; for example, the parts of the program that are 398 unreachable could be optimized away. 399 40020141222: 401 The old NFS client and server (kernel options NFSCLIENT, NFSSERVER) 402 kernel sources have been removed. The .h files remain, since some 403 utilities include them. This will need to be fixed later. 404 If "mount -t oldnfs ..." is attempted, it will fail. 405 If the "-o" option on mountd(8), nfsd(8) or nfsstat(1) is used, 406 the utilities will report errors. 407 40820141121: 409 The handling of LOCAL_LIB_DIRS has been altered to skip addition of 410 directories to top level SUBDIR variable when their parent 411 directory is included in LOCAL_DIRS. Users with build systems with 412 such hierarchies and without SUBDIR entries in the parent 413 directory Makefiles should add them or add the directories to 414 LOCAL_DIRS. 415 41620141109: 417 faith(4) and faithd(8) have been removed from the base system. Faith 418 has been obsolete for a very long time. 419 42020141104: 421 vt(4), the new console driver, is enabled by default. It brings 422 support for Unicode and double-width characters, as well as 423 support for UEFI and integration with the KMS kernel video 424 drivers. 425 426 You may need to update your console settings in /etc/rc.conf, 427 most probably the keymap. During boot, /etc/rc.d/syscons will 428 indicate what you need to do. 429 430 vt(4) still has issues and lacks some features compared to 431 syscons(4). See the wiki for up-to-date information: 432 https://wiki.freebsd.org/Newcons 433 434 If you want to keep using syscons(4), you can do so by adding 435 the following line to /boot/loader.conf: 436 kern.vty=sc 437 43820141102: 439 pjdfstest has been integrated into kyua as an opt-in test suite. 440 Please see share/doc/pjdfstest/README for more details on how to 441 execute it. 442 44320141009: 444 gperf has been removed from the base system for architectures 445 that use clang. Ports that require gperf will obtain it from the 446 devel/gperf port. 447 44820140923: 449 pjdfstest has been moved from tools/regression/pjdfstest to 450 contrib/pjdfstest . 451 45220140922: 453 At svn r271982, The default linux compat kernel ABI has been adjusted 454 to 2.6.18 in support of the linux-c6 compat ports infrastructure 455 update. If you wish to continue using the linux-f10 compat ports, 456 add compat.linux.osrelease=2.6.16 to your local sysctl.conf. Users are 457 encouraged to update their linux-compat packages to linux-c6 during 458 their next update cycle. 459 46020140729: 461 The ofwfb driver, used to provide a graphics console on PowerPC when 462 using vt(4), no longer allows mmap() of all physical memory. This 463 will prevent Xorg on PowerPC with some ATI graphics cards from 464 initializing properly unless x11-servers/xorg-server is updated to 465 1.12.4_8 or newer. 466 46720140723: 468 The xdev targets have been converted to using TARGET and 469 TARGET_ARCH instead of XDEV and XDEV_ARCH. 470 47120140719: 472 The default unbound configuration has been modified to address 473 issues with reverse lookups on networks that use private 474 address ranges. If you use the local_unbound service, run 475 "service local_unbound setup" as root to regenerate your 476 configuration, then "service local_unbound reload" to load the 477 new configuration. 478 47920140709: 480 The GNU texinfo and GNU info pages are not built and installed 481 anymore, WITH_INFO knob has been added to allow to built and install 482 them again. 483 UPDATE: see 20150102 entry on texinfo's removal 484 48520140708: 486 The GNU readline library is now an INTERNALLIB - that is, it is 487 statically linked into consumers (GDB and variants) in the base 488 system, and the shared library is no longer installed. The 489 devel/readline port is available for third party software that 490 requires readline. 491 49220140702: 493 The Itanium architecture (ia64) has been removed from the list of 494 known architectures. This is the first step in the removal of the 495 architecture. 496 49720140701: 498 Commit r268115 has added NFSv4.1 server support, merged from 499 projects/nfsv4.1-server. Since this includes changes to the 500 internal interfaces between the NFS related modules, a full 501 build of the kernel and modules will be necessary. 502 __FreeBSD_version has been bumped. 503 50420140629: 505 The WITHOUT_VT_SUPPORT kernel config knob has been renamed 506 WITHOUT_VT. (The other _SUPPORT knobs have a consistent meaning 507 which differs from the behaviour controlled by this knob.) 508 50920140619: 510 Maximal length of the serial number in CTL was increased from 16 to 511 64 chars, that breaks ABI. All CTL-related tools, such as ctladm 512 and ctld, need to be rebuilt to work with a new kernel. 513 51420140606: 515 The libatf-c and libatf-c++ major versions were downgraded to 0 and 516 1 respectively to match the upstream numbers. They were out of 517 sync because, when they were originally added to FreeBSD, the 518 upstream versions were not respected. These libraries are private 519 and not yet built by default, so renumbering them should be a 520 non-issue. However, unclean source trees will yield broken test 521 programs once the operator executes "make delete-old-libs" after a 522 "make installworld". 523 524 Additionally, the atf-sh binary was made private by moving it into 525 /usr/libexec/. Already-built shell test programs will keep the 526 path to the old binary so they will break after "make delete-old" 527 is run. 528 529 If you are using WITH_TESTS=yes (not the default), wipe the object 530 tree and rebuild from scratch to prevent spurious test failures. 531 This is only needed once: the misnumbered libraries and misplaced 532 binaries have been added to OptionalObsoleteFiles.inc so they will 533 be removed during a clean upgrade. 534 53520140512: 536 Clang and llvm have been upgraded to 3.4.1 release. 537 53820140508: 539 We bogusly installed src.opts.mk in /usr/share/mk. This file should 540 be removed to avoid issues in the future (and has been added to 541 ObsoleteFiles.inc). 542 54320140505: 544 /etc/src.conf now affects only builds of the FreeBSD src tree. In the 545 past, it affected all builds that used the bsd.*.mk files. The old 546 behavior was a bug, but people may have relied upon it. To get this 547 behavior back, you can .include /etc/src.conf from /etc/make.conf 548 (which is still global and isn't changed). This also changes the 549 behavior of incremental builds inside the tree of individual 550 directories. Set MAKESYSPATH to ".../share/mk" to do that. 551 Although this has survived make universe and some upgrade scenarios, 552 other upgrade scenarios may have broken. At least one form of 553 temporary breakage was fixed with MAKESYSPATH settings for buildworld 554 as well... In cases where MAKESYSPATH isn't working with this 555 setting, you'll need to set it to the full path to your tree. 556 557 One side effect of all this cleaning up is that bsd.compiler.mk 558 is no longer implicitly included by bsd.own.mk. If you wish to 559 use COMPILER_TYPE, you must now explicitly include bsd.compiler.mk 560 as well. 561 56220140430: 563 The lindev device has been removed since /dev/full has been made a 564 standard device. __FreeBSD_version has been bumped. 565 56620140424: 567 The knob WITHOUT_VI was added to the base system, which controls 568 building ex(1), vi(1), etc. Older releases of FreeBSD required ex(1) 569 in order to reorder files share/termcap and didn't build ex(1) as a 570 build tool, so building/installing with WITH_VI is highly advised for 571 build hosts for older releases. 572 573 This issue has been fixed in stable/9 and stable/10 in r277022 and 574 r276991, respectively. 575 57620140418: 577 The YES_HESIOD knob has been removed. It has been obsolete for 578 a decade. Please move to using WITH_HESIOD instead or your builds 579 will silently lack HESIOD. 580 58120140405: 582 The uart(4) driver has been changed with respect to its handling 583 of the low-level console. Previously the uart(4) driver prevented 584 any process from changing the baudrate or the CLOCAL and HUPCL 585 control flags. By removing the restrictions, operators can make 586 changes to the serial console port without having to reboot. 587 However, when getty(8) is started on the serial device that is 588 associated with the low-level console, a misconfigured terminal 589 line in /etc/ttys will now have a real impact. 590 Before upgrading the kernel, make sure that /etc/ttys has the 591 serial console device configured as 3wire without baudrate to 592 preserve the previous behaviour. E.g: 593 ttyu0 "/usr/libexec/getty 3wire" vt100 on secure 594 59520140306: 596 Support for libwrap (TCP wrappers) in rpcbind was disabled by default 597 to improve performance. To re-enable it, if needed, run rpcbind 598 with command line option -W. 599 60020140226: 601 Switched back to the GPL dtc compiler due to updates in the upstream 602 dts files not being supported by the BSDL dtc compiler. You will need 603 to rebuild your kernel toolchain to pick up the new compiler. Core dumps 604 may result while building dtb files during a kernel build if you fail 605 to do so. Set WITHOUT_GPL_DTC if you require the BSDL compiler. 606 60720140216: 608 Clang and llvm have been upgraded to 3.4 release. 609 61020140216: 611 The nve(4) driver has been removed. Please use the nfe(4) driver 612 for NVIDIA nForce MCP Ethernet adapters instead. 613 61420140212: 615 An ABI incompatibility crept into the libc++ 3.4 import in r261283. 616 This could cause certain C++ applications using shared libraries built 617 against the previous version of libc++ to crash. The incompatibility 618 has now been fixed, but any C++ applications or shared libraries built 619 between r261283 and r261801 should be recompiled. 620 62120140204: 622 OpenSSH will now ignore errors caused by kernel lacking of Capsicum 623 capability mode support. Please note that enabling the feature in 624 kernel is still highly recommended. 625 62620140131: 627 OpenSSH is now built with sandbox support, and will use sandbox as 628 the default privilege separation method. This requires Capsicum 629 capability mode support in kernel. 630 63120140128: 632 The libelf and libdwarf libraries have been updated to newer 633 versions from upstream. Shared library version numbers for 634 these two libraries were bumped. Any ports or binaries 635 requiring these two libraries should be recompiled. 636 __FreeBSD_version is bumped to 1100006. 637 63820140110: 639 If a Makefile in a tests/ directory was auto-generating a Kyuafile 640 instead of providing an explicit one, this would prevent such 641 Makefile from providing its own Kyuafile in the future during 642 NO_CLEAN builds. This has been fixed in the Makefiles but manual 643 intervention is needed to clean an objdir if you use NO_CLEAN: 644 # find /usr/obj -name Kyuafile | xargs rm -f 645 64620131213: 647 The behavior of gss_pseudo_random() for the krb5 mechanism 648 has changed, for applications requesting a longer random string 649 than produced by the underlying enctype's pseudo-random() function. 650 In particular, the random string produced from a session key of 651 enctype aes256-cts-hmac-sha1-96 or aes256-cts-hmac-sha1-96 will 652 be different at the 17th octet and later, after this change. 653 The counter used in the PRF+ construction is now encoded as a 654 big-endian integer in accordance with RFC 4402. 655 __FreeBSD_version is bumped to 1100004. 656 65720131108: 658 The WITHOUT_ATF build knob has been removed and its functionality 659 has been subsumed into the more generic WITHOUT_TESTS. If you were 660 using the former to disable the build of the ATF libraries, you 661 should change your settings to use the latter. 662 66320131025: 664 The default version of mtree is nmtree which is obtained from 665 NetBSD. The output is generally the same, but may vary 666 slightly. If you found you need identical output adding 667 "-F freebsd9" to the command line should do the trick. For the 668 time being, the old mtree is available as fmtree. 669 67020131014: 671 libbsdyml has been renamed to libyaml and moved to /usr/lib/private. 672 This will break ports-mgmt/pkg. Rebuild the port, or upgrade to pkg 673 1.1.4_8 and verify bsdyml not linked in, before running "make 674 delete-old-libs": 675 # make -C /usr/ports/ports-mgmt/pkg build deinstall install clean 676 or 677 # pkg install pkg; ldd /usr/local/sbin/pkg | grep bsdyml 678 67920131010: 680 The stable/10 branch has been created in subversion from head 681 revision r256279. 682 68320131010: 684 The rc.d/jail script has been updated to support jail(8) 685 configuration file. The "jail_<jname>_*" rc.conf(5) variables 686 for per-jail configuration are automatically converted to 687 /var/run/jail.<jname>.conf before the jail(8) utility is invoked. 688 This is transparently backward compatible. See below about some 689 incompatibilities and rc.conf(5) manual page for more details. 690 691 These variables are now deprecated in favor of jail(8) configuration 692 file. One can use "rc.d/jail config <jname>" command to generate 693 a jail(8) configuration file in /var/run/jail.<jname>.conf without 694 running the jail(8) utility. The default pathname of the 695 configuration file is /etc/jail.conf and can be specified by 696 using $jail_conf or $jail_<jname>_conf variables. 697 698 Please note that jail_devfs_ruleset accepts an integer at 699 this moment. Please consider to rewrite the ruleset name 700 with an integer. 701 70220130930: 703 BIND has been removed from the base system. If all you need 704 is a local resolver, simply enable and start the local_unbound 705 service instead. Otherwise, several versions of BIND are 706 available in the ports tree. The dns/bind99 port is one example. 707 708 With this change, nslookup(1) and dig(1) are no longer in the base 709 system. Users should instead use host(1) and drill(1) which are 710 in the base system. Alternatively, nslookup and dig can 711 be obtained by installing the dns/bind-tools port. 712 71320130916: 714 With the addition of unbound(8), a new unbound user is now 715 required during installworld. "mergemaster -p" can be used to 716 add the user prior to installworld, as documented in the handbook. 717 71820130911: 719 OpenSSH is now built with DNSSEC support, and will by default 720 silently trust signed SSHFP records. This can be controlled with 721 the VerifyHostKeyDNS client configuration setting. DNSSEC support 722 can be disabled entirely with the WITHOUT_LDNS option in src.conf. 723 72420130906: 725 The GNU Compiler Collection and C++ standard library (libstdc++) 726 are no longer built by default on platforms where clang is the system 727 compiler. You can enable them with the WITH_GCC and WITH_GNUCXX 728 options in src.conf. 729 73020130905: 731 The PROCDESC kernel option is now part of the GENERIC kernel 732 configuration and is required for the rwhod(8) to work. 733 If you are using custom kernel configuration, you should include 734 'options PROCDESC'. 735 73620130905: 737 The API and ABI related to the Capsicum framework was modified 738 in backward incompatible way. The userland libraries and programs 739 have to be recompiled to work with the new kernel. This includes the 740 following libraries and programs, but the whole buildworld is 741 advised: libc, libprocstat, dhclient, tcpdump, hastd, hastctl, 742 kdump, procstat, rwho, rwhod, uniq. 743 74420130903: 745 AES-NI intrinsic support has been added to gcc. The AES-NI module 746 has been updated to use this support. A new gcc is required to build 747 the aesni module on both i386 and amd64. 748 74920130821: 750 The PADLOCK_RNG and RDRAND_RNG kernel options are now devices. 751 Thus "device padlock_rng" and "device rdrand_rng" should be 752 used instead of "options PADLOCK_RNG" & "options RDRAND_RNG". 753 75420130813: 755 WITH_ICONV has been split into two feature sets. WITH_ICONV now 756 enables just the iconv* functionality and is now on by default. 757 WITH_LIBICONV_COMPAT enables the libiconv api and link time 758 compatability. Set WITHOUT_ICONV to build the old way. 759 If you have been using WITH_ICONV before, you will very likely 760 need to turn on WITH_LIBICONV_COMPAT. 761 76220130806: 763 INVARIANTS option now enables DEBUG for code with OpenSolaris and 764 Illumos origin, including ZFS. If you have INVARIANTS in your 765 kernel configuration, then there is no need to set DEBUG or ZFS_DEBUG 766 explicitly. 767 DEBUG used to enable witness(9) tracking of OpenSolaris (mostly ZFS) 768 locks if WITNESS option was set. Because that generated a lot of 769 witness(9) reports and all of them were believed to be false 770 positives, this is no longer done. New option OPENSOLARIS_WITNESS 771 can be used to achieve the previous behavior. 772 77320130806: 774 Timer values in IPv6 data structures now use time_uptime instead 775 of time_second. Although this is not a user-visible functional 776 change, userland utilities which directly use them---ndp(8), 777 rtadvd(8), and rtsold(8) in the base system---need to be updated 778 to r253970 or later. 779 78020130802: 781 find -delete can now delete the pathnames given as arguments, 782 instead of only files found below them or if the pathname did 783 not contain any slashes. Formerly, the following error message 784 would result: 785 786 find: -delete: <path>: relative path potentially not safe 787 788 Deleting the pathnames given as arguments can be prevented 789 without error messages using -mindepth 1 or by changing 790 directory and passing "." as argument to find. This works in the 791 old as well as the new version of find. 792 79320130726: 794 Behavior of devfs rules path matching has been changed. 795 Pattern is now always matched against fully qualified devfs 796 path and slash characters must be explicitly matched by 797 slashes in pattern (FNM_PATHNAME). Rulesets involving devfs 798 subdirectories must be reviewed. 799 80020130716: 801 The default ARM ABI has changed to the ARM EABI. The old ABI is 802 incompatible with the ARM EABI and all programs and modules will 803 need to be rebuilt to work with a new kernel. 804 805 To keep using the old ABI ensure the WITHOUT_ARM_EABI knob is set. 806 807 NOTE: Support for the old ABI will be removed in the future and 808 users are advised to upgrade. 809 81020130709: 811 pkg_install has been disconnected from the build if you really need it 812 you should add WITH_PKGTOOLS in your src.conf(5). 813 81420130709: 815 Most of network statistics structures were changed to be able 816 keep 64-bits counters. Thus all tools, that work with networking 817 statistics, must be rebuilt (netstat(1), bsnmpd(1), etc.) 818 81920130629: 820 Fix targets that run multiple make's to use && rather than ; 821 so that subsequent steps depend on success of previous. 822 823 NOTE: if building 'universe' with -j* on stable/8 or stable/9 824 it would be better to start the build using bmake, to avoid 825 overloading the machine. 826 82720130618: 828 Fix a bug that allowed a tracing process (e.g. gdb) to write 829 to a memory-mapped file in the traced process's address space 830 even if neither the traced process nor the tracing process had 831 write access to that file. 832 83320130615: 834 CVS has been removed from the base system. An exact copy 835 of the code is available from the devel/cvs port. 836 83720130613: 838 Some people report the following error after the switch to bmake: 839 840 make: illegal option -- J 841 usage: make [-BPSXeiknpqrstv] [-C directory] [-D variable] 842 ... 843 *** [buildworld] Error code 2 844 845 this likely due to an old instance of make in 846 ${MAKEPATH} (${MAKEOBJDIRPREFIX}${.CURDIR}/make.${MACHINE}) 847 which src/Makefile will use that blindly, if it exists, so if 848 you see the above error: 849 850 rm -rf `make -V MAKEPATH` 851 852 should resolve it. 853 85420130516: 855 Use bmake by default. 856 Whereas before one could choose to build with bmake via 857 -DWITH_BMAKE one must now use -DWITHOUT_BMAKE to use the old 858 make. The goal is to remove these knobs for 10-RELEASE. 859 860 It is worth noting that bmake (like gmake) treats the command 861 line as the unit of failure, rather than statements within the 862 command line. Thus '(cd some/where && dosomething)' is safer 863 than 'cd some/where; dosomething'. The '()' allows consistent 864 behavior in parallel build. 865 86620130429: 867 Fix a bug that allows NFS clients to issue READDIR on files. 868 86920130426: 870 The WITHOUT_IDEA option has been removed because 871 the IDEA patent expired. 872 87320130426: 874 The sysctl which controls TRIM support under ZFS has been renamed 875 from vfs.zfs.trim_disable -> vfs.zfs.trim.enabled and has been 876 enabled by default. 877 87820130425: 879 The mergemaster command now uses the default MAKEOBJDIRPREFIX 880 rather than creating it's own in the temporary directory in 881 order allow access to bootstrapped versions of tools such as 882 install and mtree. When upgrading from version of FreeBSD where 883 the install command does not support -l, you will need to 884 install a new mergemaster command if mergemaster -p is required. 885 This can be accomplished with the command (cd src/usr.sbin/mergemaster 886 && make install). 887 88820130404: 889 Legacy ATA stack, disabled and replaced by new CAM-based one since 890 FreeBSD 9.0, completely removed from the sources. Kernel modules 891 atadisk and atapi*, user-level tools atacontrol and burncd are 892 removed. Kernel option `options ATA_CAM` is now permanently enabled 893 and removed. 894 89520130319: 896 SOCK_CLOEXEC and SOCK_NONBLOCK flags have been added to socket(2) 897 and socketpair(2). Software, in particular Kerberos, may 898 automatically detect and use these during building. The resulting 899 binaries will not work on older kernels. 900 90120130308: 902 CTL_DISABLE has also been added to the sparc64 GENERIC (for further 903 information, see the respective 20130304 entry). 904 90520130304: 906 Recent commits to callout(9) changed the size of struct callout, 907 so the KBI is probably heavily disturbed. Also, some functions 908 in callout(9)/sleep(9)/sleepqueue(9)/condvar(9) KPIs were replaced 909 by macros. Every kernel module using it won't load, so rebuild 910 is requested. 911 912 The ctl device has been re-enabled in GENERIC for i386 and amd64, 913 but does not initialize by default (because of the new CTL_DISABLE 914 option) to save memory. To re-enable it, remove the CTL_DISABLE 915 option from the kernel config file or set kern.cam.ctl.disable=0 916 in /boot/loader.conf. 917 91820130301: 919 The ctl device has been disabled in GENERIC for i386 and amd64. 920 This was done due to the extra memory being allocated at system 921 initialisation time by the ctl driver which was only used if 922 a CAM target device was created. This makes a FreeBSD system 923 unusable on 128MB or less of RAM. 924 92520130208: 926 A new compression method (lz4) has been merged to -HEAD. Please 927 refer to zpool-features(7) for more information. 928 929 Please refer to the "ZFS notes" section of this file for information 930 on upgrading boot ZFS pools. 931 93220130129: 933 A BSD-licensed patch(1) variant has been added and is installed 934 as bsdpatch, being the GNU version the default patch. 935 To inverse the logic and use the BSD-licensed one as default, 936 while having the GNU version installed as gnupatch, rebuild 937 and install world with the WITH_BSD_PATCH knob set. 938 93920130121: 940 Due to the use of the new -l option to install(1) during build 941 and install, you must take care not to directly set the INSTALL 942 make variable in your /etc/make.conf, /etc/src.conf, or on the 943 command line. If you wish to use the -C flag for all installs 944 you may be able to add INSTALL+=-C to /etc/make.conf or 945 /etc/src.conf. 946 94720130118: 948 The install(1) option -M has changed meaning and now takes an 949 argument that is a file or path to append logs to. In the 950 unlikely event that -M was the last option on the command line 951 and the command line contained at least two files and a target 952 directory the first file will have logs appended to it. The -M 953 option served little practical purpose in the last decade so its 954 use is expected to be extremely rare. 955 95620121223: 957 After switching to Clang as the default compiler some users of ZFS 958 on i386 systems started to experience stack overflow kernel panics. 959 Please consider using 'options KSTACK_PAGES=4' in such configurations. 960 96120121222: 962 GEOM_LABEL now mangles label names read from file system metadata. 963 Mangling affect labels containing spaces, non-printable characters, 964 '%' or '"'. Device names in /etc/fstab and other places may need to 965 be updated. 966 96720121217: 968 By default, only the 10 most recent kernel dumps will be saved. To 969 restore the previous behaviour (no limit on the number of kernel dumps 970 stored in the dump directory) add the following line to /etc/rc.conf: 971 972 savecore_flags="" 973 97420121201: 975 With the addition of auditdistd(8), a new auditdistd user is now 976 required during installworld. "mergemaster -p" can be used to 977 add the user prior to installworld, as documented in the handbook. 978 97920121117: 980 The sin6_scope_id member variable in struct sockaddr_in6 is now 981 filled by the kernel before passing the structure to the userland via 982 sysctl or routing socket. This means the KAME-specific embedded scope 983 id in sin6_addr.s6_addr[2] is always cleared in userland application. 984 This behavior can be controlled by net.inet6.ip6.deembed_scopeid. 985 __FreeBSD_version is bumped to 1000025. 986 98720121105: 988 On i386 and amd64 systems WITH_CLANG_IS_CC is now the default. 989 This means that the world and kernel will be compiled with clang 990 and that clang will be installed as /usr/bin/cc, /usr/bin/c++, 991 and /usr/bin/cpp. To disable this behavior and revert to building 992 with gcc, compile with WITHOUT_CLANG_IS_CC. Really old versions 993 of current may need to bootstrap WITHOUT_CLANG first if the clang 994 build fails (its compatibility window doesn't extend to the 9 stable 995 branch point). 996 99720121102: 998 The IPFIREWALL_FORWARD kernel option has been removed. Its 999 functionality now turned on by default. 1000 100120121023: 1002 The ZERO_COPY_SOCKET kernel option has been removed and 1003 split into SOCKET_SEND_COW and SOCKET_RECV_PFLIP. 1004 NB: SOCKET_SEND_COW uses the VM page based copy-on-write 1005 mechanism which is not safe and may result in kernel crashes. 1006 NB: The SOCKET_RECV_PFLIP mechanism is useless as no current 1007 driver supports disposeable external page sized mbuf storage. 1008 Proper replacements for both zero-copy mechanisms are under 1009 consideration and will eventually lead to complete removal 1010 of the two kernel options. 1011 101220121023: 1013 The IPv4 network stack has been converted to network byte 1014 order. The following modules need to be recompiled together 1015 with kernel: carp(4), divert(4), gif(4), siftr(4), gre(4), 1016 pf(4), ipfw(4), ng_ipfw(4), stf(4). 1017 101820121022: 1019 Support for non-MPSAFE filesystems was removed from VFS. The 1020 VFS_VERSION was bumped, all filesystem modules shall be 1021 recompiled. 1022 102320121018: 1024 All the non-MPSAFE filesystems have been disconnected from 1025 the build. The full list includes: codafs, hpfs, ntfs, nwfs, 1026 portalfs, smbfs, xfs. 1027 102820121016: 1029 The interface cloning API and ABI has changed. The following 1030 modules need to be recompiled together with kernel: 1031 ipfw(4), pfsync(4), pflog(4), usb(4), wlan(4), stf(4), 1032 vlan(4), disc(4), edsc(4), if_bridge(4), gif(4), tap(4), 1033 faith(4), epair(4), enc(4), tun(4), if_lagg(4), gre(4). 1034 103520121015: 1036 The sdhci driver was split in two parts: sdhci (generic SD Host 1037 Controller logic) and sdhci_pci (actual hardware driver). 1038 No kernel config modifications are required, but if you 1039 load sdhc as a module you must switch to sdhci_pci instead. 1040 104120121014: 1042 Import the FUSE kernel and userland support into base system. 1043 104420121013: 1045 The GNU sort(1) program has been removed since the BSD-licensed 1046 sort(1) has been the default for quite some time and no serious 1047 problems have been reported. The corresponding WITH_GNU_SORT 1048 knob has also gone. 1049 105020121006: 1051 The pfil(9) API/ABI for AF_INET family has been changed. Packet 1052 filtering modules: pf(4), ipfw(4), ipfilter(4) need to be recompiled 1053 with new kernel. 1054 105520121001: 1056 The net80211(4) ABI has been changed to allow for improved driver 1057 PS-POLL and power-save support. All wireless drivers need to be 1058 recompiled to work with the new kernel. 1059 106020120913: 1061 The random(4) support for the VIA hardware random number 1062 generator (`PADLOCK') is no longer enabled unconditionally. 1063 Add the padlock_rng device in the custom kernel config if 1064 needed. The GENERIC kernels on i386 and amd64 do include the 1065 device, so the change only affects the custom kernel 1066 configurations. 1067 106820120908: 1069 The pf(4) packet filter ABI has been changed. pfctl(8) and 1070 snmp_pf module need to be recompiled to work with new kernel. 1071 107220120828: 1073 A new ZFS feature flag "com.delphix:empty_bpobj" has been merged 1074 to -HEAD. Pools that have empty_bpobj in active state can not be 1075 imported read-write with ZFS implementations that do not support 1076 this feature. For more information read the zpool-features(5) 1077 manual page. 1078 107920120727: 1080 The sparc64 ZFS loader has been changed to no longer try to auto- 1081 detect ZFS providers based on diskN aliases but now requires these 1082 to be explicitly listed in the OFW boot-device environment variable. 1083 108420120712: 1085 The OpenSSL has been upgraded to 1.0.1c. Any binaries requiring 1086 libcrypto.so.6 or libssl.so.6 must be recompiled. Also, there are 1087 configuration changes. Make sure to merge /etc/ssl/openssl.cnf. 1088 108920120712: 1090 The following sysctls and tunables have been renamed for consistency 1091 with other variables: 1092 kern.cam.da.da_send_ordered -> kern.cam.da.send_ordered 1093 kern.cam.ada.ada_send_ordered -> kern.cam.ada.send_ordered 1094 109520120628: 1096 The sort utility has been replaced with BSD sort. For now, GNU sort 1097 is also available as "gnusort" or the default can be set back to 1098 GNU sort by setting WITH_GNU_SORT. In this case, BSD sort will be 1099 installed as "bsdsort". 1100 110120120611: 1102 A new version of ZFS (pool version 5000) has been merged to -HEAD. 1103 Starting with this version the old system of ZFS pool versioning 1104 is superseded by "feature flags". This concept enables forward 1105 compatibility against certain future changes in functionality of ZFS 1106 pools. The first read-only compatible "feature flag" for ZFS pools 1107 is named "com.delphix:async_destroy". For more information 1108 read the new zpool-features(5) manual page. 1109 Please refer to the "ZFS notes" section of this file for information 1110 on upgrading boot ZFS pools. 1111 111220120417: 1113 The malloc(3) implementation embedded in libc now uses sources imported 1114 as contrib/jemalloc. The most disruptive API change is to 1115 /etc/malloc.conf. If your system has an old-style /etc/malloc.conf, 1116 delete it prior to installworld, and optionally re-create it using the 1117 new format after rebooting. See malloc.conf(5) for details 1118 (specifically the TUNING section and the "opt.*" entries in the MALLCTL 1119 NAMESPACE section). 1120 112120120328: 1122 Big-endian MIPS TARGET_ARCH values no longer end in "eb". mips64eb 1123 is now spelled mips64. mipsn32eb is now spelled mipsn32. mipseb is 1124 now spelled mips. This is to aid compatibility with third-party 1125 software that expects this naming scheme in uname(3). Little-endian 1126 settings are unchanged. If you are updating a big-endian mips64 machine 1127 from before this change, you may need to set MACHINE_ARCH=mips64 in 1128 your environment before the new build system will recognize your machine. 1129 113020120306: 1131 Disable by default the option VFS_ALLOW_NONMPSAFE for all supported 1132 platforms. 1133 113420120229: 1135 Now unix domain sockets behave "as expected" on nullfs(5). Previously 1136 nullfs(5) did not pass through all behaviours to the underlying layer, 1137 as a result if we bound to a socket on the lower layer we could connect 1138 only to the lower path; if we bound to the upper layer we could connect 1139 only to the upper path. The new behavior is one can connect to both the 1140 lower and the upper paths regardless what layer path one binds to. 1141 114220120211: 1143 The getifaddrs upgrade path broken with 20111215 has been restored. 1144 If you have upgraded in between 20111215 and 20120209 you need to 1145 recompile libc again with your kernel. You still need to recompile 1146 world to be able to configure CARP but this restriction already 1147 comes from 20111215. 1148 114920120114: 1150 The set_rcvar() function has been removed from /etc/rc.subr. All 1151 base and ports rc.d scripts have been updated, so if you have a 1152 port installed with a script in /usr/local/etc/rc.d you can either 1153 hand-edit the rcvar= line, or reinstall the port. 1154 1155 An easy way to handle the mass-update of /etc/rc.d: 1156 rm /etc/rc.d/* && mergemaster -i 1157 115820120109: 1159 panic(9) now stops other CPUs in the SMP systems, disables interrupts 1160 on the current CPU and prevents other threads from running. 1161 This behavior can be reverted using the kern.stop_scheduler_on_panic 1162 tunable/sysctl. 1163 The new behavior can be incompatible with kern.sync_on_panic. 1164 116520111215: 1166 The carp(4) facility has been changed significantly. Configuration 1167 of the CARP protocol via ifconfig(8) has changed, as well as format 1168 of CARP events submitted to devd(8) has changed. See manual pages 1169 for more information. The arpbalance feature of carp(4) is currently 1170 not supported anymore. 1171 1172 Size of struct in_aliasreq, struct in6_aliasreq has changed. User 1173 utilities using SIOCAIFADDR, SIOCAIFADDR_IN6, e.g. ifconfig(8), 1174 need to be recompiled. 1175 117620111122: 1177 The acpi_wmi(4) status device /dev/wmistat has been renamed to 1178 /dev/wmistat0. 1179 118020111108: 1181 The option VFS_ALLOW_NONMPSAFE option has been added in order to 1182 explicitely support non-MPSAFE filesystems. 1183 It is on by default for all supported platform at this present 1184 time. 1185 118620111101: 1187 The broken amd(4) driver has been replaced with esp(4) in the amd64, 1188 i386 and pc98 GENERIC kernel configuration files. 1189 119020110930: 1191 sysinstall has been removed 1192 119320110923: 1194 The stable/9 branch created in subversion. This corresponds to the 1195 RELENG_9 branch in CVS. 1196 1197COMMON ITEMS: 1198 1199 General Notes 1200 ------------- 1201 Avoid using make -j when upgrading. While generally safe, there are 1202 sometimes problems using -j to upgrade. If your upgrade fails with 1203 -j, please try again without -j. From time to time in the past there 1204 have been problems using -j with buildworld and/or installworld. This 1205 is especially true when upgrading between "distant" versions (eg one 1206 that cross a major release boundary or several minor releases, or when 1207 several months have passed on the -current branch). 1208 1209 Sometimes, obscure build problems are the result of environment 1210 poisoning. This can happen because the make utility reads its 1211 environment when searching for values for global variables. To run 1212 your build attempts in an "environmental clean room", prefix all make 1213 commands with 'env -i '. See the env(1) manual page for more details. 1214 1215 When upgrading from one major version to another it is generally best 1216 to upgrade to the latest code in the currently installed branch first, 1217 then do an upgrade to the new branch. This is the best-tested upgrade 1218 path, and has the highest probability of being successful. Please try 1219 this approach before reporting problems with a major version upgrade. 1220 1221 When upgrading a live system, having a root shell around before 1222 installing anything can help undo problems. Not having a root shell 1223 around can lead to problems if pam has changed too much from your 1224 starting point to allow continued authentication after the upgrade. 1225 1226 This file should be read as a log of events. When a later event changes 1227 information of a prior event, the prior event should not be deleted. 1228 Instead, a pointer to the entry with the new information should be 1229 placed in the old entry. Readers of this file should also sanity check 1230 older entries before relying on them blindly. Authors of new entries 1231 should write them with this in mind. 1232 1233 ZFS notes 1234 --------- 1235 When upgrading the boot ZFS pool to a new version, always follow 1236 these two steps: 1237 1238 1.) recompile and reinstall the ZFS boot loader and boot block 1239 (this is part of "make buildworld" and "make installworld") 1240 1241 2.) update the ZFS boot block on your boot drive 1242 1243 The following example updates the ZFS boot block on the first 1244 partition (freebsd-boot) of a GPT partitioned drive ada0: 1245 "gpart bootcode -p /boot/gptzfsboot -i 1 ada0" 1246 1247 Non-boot pools do not need these updates. 1248 1249 To build a kernel 1250 ----------------- 1251 If you are updating from a prior version of FreeBSD (even one just 1252 a few days old), you should follow this procedure. It is the most 1253 failsafe as it uses a /usr/obj tree with a fresh mini-buildworld, 1254 1255 make kernel-toolchain 1256 make -DALWAYS_CHECK_MAKE buildkernel KERNCONF=YOUR_KERNEL_HERE 1257 make -DALWAYS_CHECK_MAKE installkernel KERNCONF=YOUR_KERNEL_HERE 1258 1259 To test a kernel once 1260 --------------------- 1261 If you just want to boot a kernel once (because you are not sure 1262 if it works, or if you want to boot a known bad kernel to provide 1263 debugging information) run 1264 make installkernel KERNCONF=YOUR_KERNEL_HERE KODIR=/boot/testkernel 1265 nextboot -k testkernel 1266 1267 To just build a kernel when you know that it won't mess you up 1268 -------------------------------------------------------------- 1269 This assumes you are already running a CURRENT system. Replace 1270 ${arch} with the architecture of your machine (e.g. "i386", 1271 "arm", "amd64", "ia64", "pc98", "sparc64", "powerpc", "mips", etc). 1272 1273 cd src/sys/${arch}/conf 1274 config KERNEL_NAME_HERE 1275 cd ../compile/KERNEL_NAME_HERE 1276 make depend 1277 make 1278 make install 1279 1280 If this fails, go to the "To build a kernel" section. 1281 1282 To rebuild everything and install it on the current system. 1283 ----------------------------------------------------------- 1284 # Note: sometimes if you are running current you gotta do more than 1285 # is listed here if you are upgrading from a really old current. 1286 1287 <make sure you have good level 0 dumps> 1288 make buildworld 1289 make kernel KERNCONF=YOUR_KERNEL_HERE 1290 [1] 1291 <reboot in single user> [3] 1292 mergemaster -Fp [5] 1293 make installworld 1294 mergemaster -Fi [4] 1295 make delete-old [6] 1296 <reboot> 1297 1298 To cross-install current onto a separate partition 1299 -------------------------------------------------- 1300 # In this approach we use a separate partition to hold 1301 # current's root, 'usr', and 'var' directories. A partition 1302 # holding "/", "/usr" and "/var" should be about 2GB in 1303 # size. 1304 1305 <make sure you have good level 0 dumps> 1306 <boot into -stable> 1307 make buildworld 1308 make buildkernel KERNCONF=YOUR_KERNEL_HERE 1309 <maybe newfs current's root partition> 1310 <mount current's root partition on directory ${CURRENT_ROOT}> 1311 make installworld DESTDIR=${CURRENT_ROOT} -DDB_FROM_SRC 1312 make distribution DESTDIR=${CURRENT_ROOT} # if newfs'd 1313 make installkernel KERNCONF=YOUR_KERNEL_HERE DESTDIR=${CURRENT_ROOT} 1314 cp /etc/fstab ${CURRENT_ROOT}/etc/fstab # if newfs'd 1315 <edit ${CURRENT_ROOT}/etc/fstab to mount "/" from the correct partition> 1316 <reboot into current> 1317 <do a "native" rebuild/install as described in the previous section> 1318 <maybe install compatibility libraries from ports/misc/compat*> 1319 <reboot> 1320 1321 1322 To upgrade in-place from stable to current 1323 ---------------------------------------------- 1324 <make sure you have good level 0 dumps> 1325 make buildworld [9] 1326 make kernel KERNCONF=YOUR_KERNEL_HERE [8] 1327 [1] 1328 <reboot in single user> [3] 1329 mergemaster -Fp [5] 1330 make installworld 1331 mergemaster -Fi [4] 1332 make delete-old [6] 1333 <reboot> 1334 1335 Make sure that you've read the UPDATING file to understand the 1336 tweaks to various things you need. At this point in the life 1337 cycle of current, things change often and you are on your own 1338 to cope. The defaults can also change, so please read ALL of 1339 the UPDATING entries. 1340 1341 Also, if you are tracking -current, you must be subscribed to 1342 freebsd-current@freebsd.org. Make sure that before you update 1343 your sources that you have read and understood all the recent 1344 messages there. If in doubt, please track -stable which has 1345 much fewer pitfalls. 1346 1347 [1] If you have third party modules, such as vmware, you 1348 should disable them at this point so they don't crash your 1349 system on reboot. 1350 1351 [3] From the bootblocks, boot -s, and then do 1352 fsck -p 1353 mount -u / 1354 mount -a 1355 cd src 1356 adjkerntz -i # if CMOS is wall time 1357 Also, when doing a major release upgrade, it is required that 1358 you boot into single user mode to do the installworld. 1359 1360 [4] Note: This step is non-optional. Failure to do this step 1361 can result in a significant reduction in the functionality of the 1362 system. Attempting to do it by hand is not recommended and those 1363 that pursue this avenue should read this file carefully, as well 1364 as the archives of freebsd-current and freebsd-hackers mailing lists 1365 for potential gotchas. The -U option is also useful to consider. 1366 See mergemaster(8) for more information. 1367 1368 [5] Usually this step is a noop. However, from time to time 1369 you may need to do this if you get unknown user in the following 1370 step. It never hurts to do it all the time. You may need to 1371 install a new mergemaster (cd src/usr.sbin/mergemaster && make 1372 install) after the buildworld before this step if you last updated 1373 from current before 20130425 or from -stable before 20130430. 1374 1375 [6] This only deletes old files and directories. Old libraries 1376 can be deleted by "make delete-old-libs", but you have to make 1377 sure that no program is using those libraries anymore. 1378 1379 [8] In order to have a kernel that can run the 4.x binaries needed to 1380 do an installworld, you must include the COMPAT_FREEBSD4 option in 1381 your kernel. Failure to do so may leave you with a system that is 1382 hard to boot to recover. A similar kernel option COMPAT_FREEBSD5 is 1383 required to run the 5.x binaries on more recent kernels. And so on 1384 for COMPAT_FREEBSD6 and COMPAT_FREEBSD7. 1385 1386 Make sure that you merge any new devices from GENERIC since the 1387 last time you updated your kernel config file. 1388 1389 [9] When checking out sources, you must include the -P flag to have 1390 cvs prune empty directories. 1391 1392 If CPUTYPE is defined in your /etc/make.conf, make sure to use the 1393 "?=" instead of the "=" assignment operator, so that buildworld can 1394 override the CPUTYPE if it needs to. 1395 1396 MAKEOBJDIRPREFIX must be defined in an environment variable, and 1397 not on the command line, or in /etc/make.conf. buildworld will 1398 warn if it is improperly defined. 1399FORMAT: 1400 1401This file contains a list, in reverse chronological order, of major 1402breakages in tracking -current. It is not guaranteed to be a complete 1403list of such breakages, and only contains entries since September 23, 2011. 1404If you need to see UPDATING entries from before that date, you will need 1405to fetch an UPDATING file from an older FreeBSD release. 1406 1407Copyright information: 1408 1409Copyright 1998-2009 M.
