UPDATING revision 296417
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 3420160305: 35 Clang, llvm, lldb and compiler-rt have been upgraded to 3.8.0. Please 36 see the 20141231 entry below for information about prerequisites and 37 upgrading, if you are not already using clang 3.5.0 or higher. 38 3920160301: 40 The AIO subsystem is now a standard part of the kernel. The 41 VFS_AIO kernel option and aio.ko kernel module have been removed. 42 Due to stability concerns, asynchronous I/O requests are only 43 permitted on sockets and raw disks by default. To enable 44 asynchronous I/O requests on all file types, set the 45 vfs.aio.enable_unsafe sysctl to a non-zero value. 46 4720160226: 48 The ELF object manipulation tool objcopy is now provided by the 49 ELF Tool Chain project rather than by GNU binutils. It should be a 50 drop-in replacement, with the addition of arm64 support. The 51 (temporary) src.conf knob WITHOUT_ELFCOPY_AS_OBJCOPY knob may be set 52 to obtain the GNU version if necessary. 53 5420160129: 55 Building ZFS pools on top of zvols is prohibited by default. That 56 feature has never worked safely; it's always been prone to deadlocks. 57 Using a zvol as the backing store for a VM guest's virtual disk will 58 still work, even if the guest is using ZFS. Legacy behavior can be 59 restored by setting vfs.zfs.vol.recursive=1. 60 6120160119: 62 The NONE and HPN patches has been removed from OpenSSH. They are 63 still available in the security/openssh-portable port. 64 6520160113: 66 With the addition of ypldap(8), a new _ypldap user is now required 67 during installworld. "mergemaster -p" can be used to add the user 68 prior to installworld, as documented in the handbook. 69 7020151216: 71 The tftp loader (pxeboot) now uses the option root-path directive. As a 72 consequence it no longer looks for a pxeboot.4th file on the tftp 73 server. Instead it uses the regular /boot infrastructure as with the 74 other loaders. 75 7620151211: 77 The code to start recording plug and play data into the modules has 78 been committed. While the old tools will properly build a new kernel, 79 a number of warnings about "unknown metadata record 4" will be produced 80 for an older kldxref. To avoid such warnings, make sure to rebuild 81 the kernel toolchain (or world). Make sure that you have r292078 or 82 later when trying to build 292077 or later before rebuilding. 83 8420151207: 85 Debug data files are now built by default with 'make buildworld' and 86 installed with 'make installworld'. This facilitates debugging but 87 requires more disk space both during the build and for the installed 88 world. Debug files may be disabled by setting WITHOUT_DEBUG_FILES=yes 89 in src.conf(5). 90 9120151130: 92 r291527 changed the internal interface between the nfsd.ko and 93 nfscommon.ko modules. As such, they must both be upgraded to-gether. 94 __FreeBSD_version has been bumped because of this. 95 9620151108: 97 Add support for unicode collation strings leads to a change of 98 order of files listed by ls(1) for example. To get back to the old 99 behaviour, set LC_COLLATE environment variable to "C". 100 101 Databases administrators will need to reindex their databases given 102 collation results will be different. 103 104 Due to a bug in install(1) it is recommended to remove the ancient 105 locales before running make installworld. 106 107 rm -rf /usr/share/locale/* 108 10920151030: 110 The OpenSSL has been upgraded to 1.0.2d. Any binaries requiring 111 libcrypto.so.7 or libssl.so.7 must be recompiled. 112 11320151020: 114 Qlogic 24xx/25xx firmware images were updated from 5.5.0 to 7.3.0. 115 Kernel modules isp_2400_multi and isp_2500_multi were removed and 116 should be replaced with isp_2400 and isp_2500 modules respectively. 117 11820151017: 119 The build previously allowed using 'make -n' to not recurse into 120 sub-directories while showing what commands would be executed, and 121 'make -n -n' to recursively show commands. Now 'make -n' will recurse 122 and 'make -N' will not. 123 12420151012: 125 If you specify SENDMAIL_MC or SENDMAIL_CF in make.conf, mergemaster 126 and etcupdate will now use this file. A custom sendmail.cf is now 127 updated via this mechanism rather than via installworld. If you had 128 excluded sendmail.cf in mergemaster.rc or etcupdate.conf, you may 129 want to remove the exclusion or change it to "always install". 130 /etc/mail/sendmail.cf is now managed the same way regardless of 131 whether SENDMAIL_MC/SENDMAIL_CF is used. If you are not using 132 SENDMAIL_MC/SENDMAIL_CF there should be no change in behavior. 133 13420151011: 135 Compatibility shims for legacy ATA device names have been removed. 136 It includes ATA_STATIC_ID kernel option, kern.cam.ada.legacy_aliases 137 and kern.geom.raid.legacy_aliases loader tunables, kern.devalias.* 138 environment variables, /dev/ad* and /dev/ar* symbolic links. 139 14020151006: 141 Clang, llvm, lldb, compiler-rt and libc++ have been upgraded to 3.7.0. 142 Please see the 20141231 entry below for information about prerequisites 143 and upgrading, if you are not already using clang 3.5.0 or higher. 144 14520150924: 146 Kernel debug files have been moved to /usr/lib/debug/boot/kernel/, 147 and renamed from .symbols to .debug. This reduces the size requirements 148 on the boot partition or file system and provides consistency with 149 userland debug files. 150 151 When using the supported kernel installation method the 152 /usr/lib/debug/boot/kernel directory will be renamed (to kernel.old) 153 as is done with /boot/kernel. 154 155 Developers wishing to maintain the historical behavior of installing 156 debug files in /boot/kernel/ can set KERN_DEBUGDIR="" in src.conf(5). 157 15820150827: 159 The wireless drivers had undergone changes that remove the 'parent 160 interface' from the ifconfig -l output. The rc.d network scripts 161 used to check presence of a parent interface in the list, so old 162 scripts would fail to start wireless networking. Thus, etcupdate(3) 163 or mergemaster(8) run is required after kernel update, to update your 164 rc.d scripts in /etc. 165 16620150827: 167 pf no longer supports 'scrub fragment crop' or 'scrub fragment drop-ovl' 168 These configurations are now automatically interpreted as 169 'scrub fragment reassemble'. 170 17120150817: 172 Kernel-loadable modules for the random(4) device are back. To use 173 them, the kernel must have 174 175 device random 176 options RANDOM_LOADABLE 177 178 kldload(8) can then be used to load random_fortuna.ko 179 or random_yarrow.ko. Please note that due to the indirect 180 function calls that the loadable modules need to provide, 181 the build-in variants will be slightly more efficient. 182 183 The random(4) kernel option RANDOM_DUMMY has been retired due to 184 unpopularity. It was not all that useful anyway. 185 18620150813: 187 The WITHOUT_ELFTOOLCHAIN_TOOLS src.conf(5) knob has been retired. 188 Control over building the ELF Tool Chain tools is now provided by 189 the WITHOUT_TOOLCHAIN knob. 190 19120150810: 192 The polarity of Pulse Per Second (PPS) capture events with the 193 uart(4) driver has been corrected. Prior to this change the PPS 194 "assert" event corresponded to the trailing edge of a positive PPS 195 pulse and the "clear" event was the leading edge of the next pulse. 196 197 As the width of a PPS pulse in a typical GPS receiver is on the 198 order of 1 millisecond, most users will not notice any significant 199 difference with this change. 200 201 Anyone who has compensated for the historical polarity reversal by 202 configuring a negative offset equal to the pulse width will need to 203 remove that workaround. 204 20520150809: 206 The default group assigned to /dev/dri entries has been changed 207 from 'wheel' to 'video' with the id of '44'. If you want to have 208 access to the dri devices please add yourself to the video group 209 with: 210 211 # pw groupmod video -m $USER 212 21320150806: 214 The menu.rc and loader.rc files will now be replaced during 215 upgrades. Please migrate local changes to menu.rc.local and 216 loader.rc.local instead. 217 21820150805: 219 GNU Binutils versions of addr2line, c++filt, nm, readelf, size, 220 strings and strip have been removed. The src.conf(5) knob 221 WITHOUT_ELFTOOLCHAIN_TOOLS no longer provides the binutils tools. 222 22320150728: 224 As ZFS requires more kernel stack pages than is the default on some 225 architectures e.g. i386, it now warns if KSTACK_PAGES is less than 226 ZFS_MIN_KSTACK_PAGES (which is 4 at the time of writing). 227 228 Please consider using 'options KSTACK_PAGES=X' where X is greater 229 than or equal to ZFS_MIN_KSTACK_PAGES i.e. 4 in such configurations. 230 23120150706: 232 sendmail has been updated to 8.15.2. Starting with FreeBSD 11.0 233 and sendmail 8.15, sendmail uses uncompressed IPv6 addresses by 234 default, i.e., they will not contain "::". For example, instead 235 of ::1, it will be 0:0:0:0:0:0:0:1. This permits a zero subnet 236 to have a more specific match, such as different map entries for 237 IPv6:0:0 vs IPv6:0. This change requires that configuration 238 data (including maps, files, classes, custom ruleset, etc.) must 239 use the same format, so make certain such configuration data is 240 upgrading. As a very simple check search for patterns like 241 'IPv6:[0-9a-fA-F:]*::' and 'IPv6::'. To return to the old 242 behavior, set the m4 option confUSE_COMPRESSED_IPV6_ADDRESSES or 243 the cf option UseCompressedIPv6Addresses. 244 24520150630: 246 The default kernel entropy-processing algorithm is now 247 Fortuna, replacing Yarrow. 248 249 Assuming you have 'device random' in your kernel config 250 file, the configurations allow a kernel option to override 251 this default. You may choose *ONE* of: 252 253 options RANDOM_YARROW # Legacy /dev/random algorithm. 254 options RANDOM_DUMMY # Blocking-only driver. 255 256 If you have neither, you get Fortuna. For most people, 257 read no further, Fortuna will give a /dev/random that works 258 like it always used to, and the difference will be irrelevant. 259 260 If you remove 'device random', you get *NO* kernel-processed 261 entropy at all. This may be acceptable to folks building 262 embedded systems, but has complications. Carry on reading, 263 and it is assumed you know what you need. 264 265 *PLEASE* read random(4) and random(9) if you are in the 266 habit of tweaking kernel configs, and/or if you are a member 267 of the embedded community, wanting specific and not-usual 268 behaviour from your security subsystems. 269 270 NOTE!! If you use RANDOM_DUMMY and/or have no 'device 271 random', you will NOT have a functioning /dev/random, and 272 many cryptographic features will not work, including SSH. 273 You may also find strange behaviour from the random(3) set 274 of library functions, in particular sranddev(3), srandomdev(3) 275 and arc4random(3). The reason for this is that the KERN_ARND 276 sysctl only returns entropy if it thinks it has some to 277 share, and with RANDOM_DUMMY or no 'device random' this 278 will never happen. 279 28020150623: 281 An additional fix for the issue described in the 20150614 sendmail 282 entry below has been been committed in revision 284717. 283 28420150616: 285 FreeBSD's old make (fmake) has been removed from the system. It is 286 available as the devel/fmake port or via pkg install fmake. 287 28820150615: 289 The fix for the issue described in the 20150614 sendmail entry 290 below has been been committed in revision 284436. The work 291 around described in that entry is no longer needed unless the 292 default setting is overridden by a confDH_PARAMETERS configuration 293 setting of '5' or pointing to a 512 bit DH parameter file. 294 29520150614: 296 ALLOW_DEPRECATED_ATF_TOOLS/ATFFILE support has been removed from 297 atf.test.mk (included from bsd.test.mk). Please upgrade devel/atf 298 and devel/kyua to version 0.20+ and adjust any calling code to work 299 with Kyuafile and kyua. 300 30120150614: 302 The import of openssl to address the FreeBSD-SA-15:10.openssl 303 security advisory includes a change which rejects handshakes 304 with DH parameters below 768 bits. sendmail releases prior 305 to 8.15.2 (not yet released), defaulted to a 512 bit 306 DH parameter setting for client connections. To work around 307 this interoperability, sendmail can be configured to use a 308 2048 bit DH parameter by: 309 310 1. Edit /etc/mail/`hostname`.mc 311 2. If a setting for confDH_PARAMETERS does not exist or 312 exists and is set to a string beginning with '5', 313 replace it with '2'. 314 3. If a setting for confDH_PARAMETERS exists and is set to 315 a file path, create a new file with: 316 openssl dhparam -out /path/to/file 2048 317 4. Rebuild the .cf file: 318 cd /etc/mail/; make; make install 319 5. Restart sendmail: 320 cd /etc/mail/; make restart 321 322 A sendmail patch is coming, at which time this file will be 323 updated. 324 32520150604: 326 Generation of legacy formatted entries have been disabled by default 327 in pwd_mkdb(8), as all base system consumers of the legacy formatted 328 entries were converted to use the new format by default when the new, 329 machine independent format have been added and supported since FreeBSD 330 5.x. 331 332 Please see the pwd_mkdb(8) manual page for further details. 333 33420150525: 335 Clang and llvm have been upgraded to 3.6.1 release. Please see the 336 20141231 entry below for information about prerequisites and upgrading, 337 if you are not already using 3.5.0 or higher. 338 33920150521: 340 TI platform code switched to using vendor DTS files and this update 341 may break existing systems running on Beaglebone, Beaglebone Black, 342 and Pandaboard: 343 344 - dtb files should be regenerated/reinstalled. Filenames are the 345 same but content is different now 346 - GPIO addressing was changed, now each GPIO bank (32 pins per bank) 347 has its own /dev/gpiocX device, e.g. pin 121 on /dev/gpioc0 in old 348 addressing scheme is now pin 25 on /dev/gpioc3. 349 - Pandaboard: /etc/ttys should be updated, serial console device is 350 now /dev/ttyu2, not /dev/ttyu0 351 35220150501: 353 soelim(1) from gnu/usr.bin/groff has been replaced by usr.bin/soelim. 354 If you need the GNU extension from groff soelim(1), install groff 355 from package: pkg install groff, or via ports: textproc/groff. 356 35720150423: 358 chmod, chflags, chown and chgrp now affect symlinks in -R mode as 359 defined in symlink(7); previously symlinks were silently ignored. 360 36120150415: 362 The const qualifier has been removed from iconv(3) to comply with 363 POSIX. The ports tree is aware of this from r384038 onwards. 364 36520150416: 366 Libraries specified by LIBADD in Makefiles must have a corresponding 367 DPADD_<lib> variable to ensure correct dependencies. This is now 368 enforced in src.libnames.mk. 369 37020150324: 371 From legacy ata(4) driver was removed support for SATA controllers 372 supported by more functional drivers ahci(4), siis(4) and mvs(4). 373 Kernel modules ataahci and ataadaptec were removed completely, 374 replaced by ahci and mvs modules respectively. 375 37620150315: 377 Clang, llvm and lldb have been upgraded to 3.6.0 release. Please see 378 the 20141231 entry below for information about prerequisites and 379 upgrading, if you are not already using 3.5.0 or higher. 380 38120150307: 382 The 32-bit PowerPC kernel has been changed to a position-independent 383 executable. This can only be booted with a version of loader(8) 384 newer than January 31, 2015, so make sure to update both world and 385 kernel before rebooting. 386 38720150217: 388 If you are running a -CURRENT kernel since r273872 (Oct 30th, 2014), 389 but before r278950, the RNG was not seeded properly. Immediately 390 upgrade the kernel to r278950 or later and regenerate any keys (e.g. 391 ssh keys or openssl keys) that were generated w/ a kernel from that 392 range. This does not affect programs that directly used /dev/random 393 or /dev/urandom. All userland uses of arc4random(3) are affected. 394 39520150210: 396 The autofs(4) ABI was changed in order to restore binary compatibility 397 with 10.1-RELEASE. The automountd(8) daemon needs to be rebuilt to work 398 with the new kernel. 399 40020150131: 401 The powerpc64 kernel has been changed to a position-independent 402 executable. This can only be booted with a new version of loader(8), 403 so make sure to update both world and kernel before rebooting. 404 40520150118: 406 Clang and llvm have been upgraded to 3.5.1 release. This is a bugfix 407 only release, no new features have been added. Please see the 20141231 408 entry below for information about prerequisites and upgrading, if you 409 are not already using 3.5.0. 410 41120150107: 412 ELF tools addr2line, elfcopy (strip), nm, size, and strings are now 413 taken from the ELF Tool Chain project rather than GNU binutils. They 414 should be drop-in replacements, with the addition of arm64 support. 415 The WITHOUT_ELFTOOLCHAIN_TOOLS= knob may be used to obtain the 416 binutils tools, if necessary. See 20150805 for updated information. 417 41820150105: 419 The default Unbound configuration now enables remote control 420 using a local socket. Users who have already enabled the 421 local_unbound service should regenerate their configuration 422 by running "service local_unbound setup" as root. 423 42420150102: 425 The GNU texinfo and GNU info pages have been removed. 426 To be able to view GNU info pages please install texinfo from ports. 427 42820141231: 429 Clang, llvm and lldb have been upgraded to 3.5.0 release. 430 431 As of this release, a prerequisite for building clang, llvm and lldb is 432 a C++11 capable compiler and C++11 standard library. This means that to 433 be able to successfully build the cross-tools stage of buildworld, with 434 clang as the bootstrap compiler, your system compiler or cross compiler 435 should either be clang 3.3 or later, or gcc 4.8 or later, and your 436 system C++ library should be libc++, or libdstdc++ from gcc 4.8 or 437 later. 438 439 On any standard FreeBSD 10.x or 11.x installation, where clang and 440 libc++ are on by default (that is, on x86 or arm), this should work out 441 of the box. 442 443 On 9.x installations where clang is enabled by default, e.g. on x86 and 444 powerpc, libc++ will not be enabled by default, so libc++ should be 445 built (with clang) and installed first. If both clang and libc++ are 446 missing, build clang first, then use it to build libc++. 447 448 On 8.x and earlier installations, upgrade to 9.x first, and then follow 449 the instructions for 9.x above. 450 451 Sparc64 and mips users are unaffected, as they still use gcc 4.2.1 by 452 default, and do not build clang. 453 454 Many embedded systems are resource constrained, and will not be able to 455 build clang in a reasonable time, or in some cases at all. In those 456 cases, cross building bootable systems on amd64 is a workaround. 457 458 This new version of clang introduces a number of new warnings, of which 459 the following are most likely to appear: 460 461 -Wabsolute-value 462 463 This warns in two cases, for both C and C++: 464 * When the code is trying to take the absolute value of an unsigned 465 quantity, which is effectively a no-op, and almost never what was 466 intended. The code should be fixed, if at all possible. If you are 467 sure that the unsigned quantity can be safely cast to signed, without 468 loss of information or undefined behavior, you can add an explicit 469 cast, or disable the warning. 470 471 * When the code is trying to take an absolute value, but the called 472 abs() variant is for the wrong type, which can lead to truncation. 473 If you want to disable the warning instead of fixing the code, please 474 make sure that truncation will not occur, or it might lead to unwanted 475 side-effects. 476 477 -Wtautological-undefined-compare and 478 -Wundefined-bool-conversion 479 480 These warn when C++ code is trying to compare 'this' against NULL, while 481 'this' should never be NULL in well-defined C++ code. However, there is 482 some legacy (pre C++11) code out there, which actively abuses this 483 feature, which was less strictly defined in previous C++ versions. 484 485 Squid and openjdk do this, for example. The warning can be turned off 486 for C++98 and earlier, but compiling the code in C++11 mode might result 487 in unexpected behavior; for example, the parts of the program that are 488 unreachable could be optimized away. 489 49020141222: 491 The old NFS client and server (kernel options NFSCLIENT, NFSSERVER) 492 kernel sources have been removed. The .h files remain, since some 493 utilities include them. This will need to be fixed later. 494 If "mount -t oldnfs ..." is attempted, it will fail. 495 If the "-o" option on mountd(8), nfsd(8) or nfsstat(1) is used, 496 the utilities will report errors. 497 49820141121: 499 The handling of LOCAL_LIB_DIRS has been altered to skip addition of 500 directories to top level SUBDIR variable when their parent 501 directory is included in LOCAL_DIRS. Users with build systems with 502 such hierarchies and without SUBDIR entries in the parent 503 directory Makefiles should add them or add the directories to 504 LOCAL_DIRS. 505 50620141109: 507 faith(4) and faithd(8) have been removed from the base system. Faith 508 has been obsolete for a very long time. 509 51020141104: 511 vt(4), the new console driver, is enabled by default. It brings 512 support for Unicode and double-width characters, as well as 513 support for UEFI and integration with the KMS kernel video 514 drivers. 515 516 You may need to update your console settings in /etc/rc.conf, 517 most probably the keymap. During boot, /etc/rc.d/syscons will 518 indicate what you need to do. 519 520 vt(4) still has issues and lacks some features compared to 521 syscons(4). See the wiki for up-to-date information: 522 https://wiki.freebsd.org/Newcons 523 524 If you want to keep using syscons(4), you can do so by adding 525 the following line to /boot/loader.conf: 526 kern.vty=sc 527 52820141102: 529 pjdfstest has been integrated into kyua as an opt-in test suite. 530 Please see share/doc/pjdfstest/README for more details on how to 531 execute it. 532 53320141009: 534 gperf has been removed from the base system for architectures 535 that use clang. Ports that require gperf will obtain it from the 536 devel/gperf port. 537 53820140923: 539 pjdfstest has been moved from tools/regression/pjdfstest to 540 contrib/pjdfstest . 541 54220140922: 543 At svn r271982, The default linux compat kernel ABI has been adjusted 544 to 2.6.18 in support of the linux-c6 compat ports infrastructure 545 update. If you wish to continue using the linux-f10 compat ports, 546 add compat.linux.osrelease=2.6.16 to your local sysctl.conf. Users are 547 encouraged to update their linux-compat packages to linux-c6 during 548 their next update cycle. 549 55020140729: 551 The ofwfb driver, used to provide a graphics console on PowerPC when 552 using vt(4), no longer allows mmap() of all physical memory. This 553 will prevent Xorg on PowerPC with some ATI graphics cards from 554 initializing properly unless x11-servers/xorg-server is updated to 555 1.12.4_8 or newer. 556 55720140723: 558 The xdev targets have been converted to using TARGET and 559 TARGET_ARCH instead of XDEV and XDEV_ARCH. 560 56120140719: 562 The default unbound configuration has been modified to address 563 issues with reverse lookups on networks that use private 564 address ranges. If you use the local_unbound service, run 565 "service local_unbound setup" as root to regenerate your 566 configuration, then "service local_unbound reload" to load the 567 new configuration. 568 56920140709: 570 The GNU texinfo and GNU info pages are not built and installed 571 anymore, WITH_INFO knob has been added to allow to built and install 572 them again. 573 UPDATE: see 20150102 entry on texinfo's removal 574 57520140708: 576 The GNU readline library is now an INTERNALLIB - that is, it is 577 statically linked into consumers (GDB and variants) in the base 578 system, and the shared library is no longer installed. The 579 devel/readline port is available for third party software that 580 requires readline. 581 58220140702: 583 The Itanium architecture (ia64) has been removed from the list of 584 known architectures. This is the first step in the removal of the 585 architecture. 586 58720140701: 588 Commit r268115 has added NFSv4.1 server support, merged from 589 projects/nfsv4.1-server. Since this includes changes to the 590 internal interfaces between the NFS related modules, a full 591 build of the kernel and modules will be necessary. 592 __FreeBSD_version has been bumped. 593 59420140629: 595 The WITHOUT_VT_SUPPORT kernel config knob has been renamed 596 WITHOUT_VT. (The other _SUPPORT knobs have a consistent meaning 597 which differs from the behaviour controlled by this knob.) 598 59920140619: 600 Maximal length of the serial number in CTL was increased from 16 to 601 64 chars, that breaks ABI. All CTL-related tools, such as ctladm 602 and ctld, need to be rebuilt to work with a new kernel. 603 60420140606: 605 The libatf-c and libatf-c++ major versions were downgraded to 0 and 606 1 respectively to match the upstream numbers. They were out of 607 sync because, when they were originally added to FreeBSD, the 608 upstream versions were not respected. These libraries are private 609 and not yet built by default, so renumbering them should be a 610 non-issue. However, unclean source trees will yield broken test 611 programs once the operator executes "make delete-old-libs" after a 612 "make installworld". 613 614 Additionally, the atf-sh binary was made private by moving it into 615 /usr/libexec/. Already-built shell test programs will keep the 616 path to the old binary so they will break after "make delete-old" 617 is run. 618 619 If you are using WITH_TESTS=yes (not the default), wipe the object 620 tree and rebuild from scratch to prevent spurious test failures. 621 This is only needed once: the misnumbered libraries and misplaced 622 binaries have been added to OptionalObsoleteFiles.inc so they will 623 be removed during a clean upgrade. 624 62520140512: 626 Clang and llvm have been upgraded to 3.4.1 release. 627 62820140508: 629 We bogusly installed src.opts.mk in /usr/share/mk. This file should 630 be removed to avoid issues in the future (and has been added to 631 ObsoleteFiles.inc). 632 63320140505: 634 /etc/src.conf now affects only builds of the FreeBSD src tree. In the 635 past, it affected all builds that used the bsd.*.mk files. The old 636 behavior was a bug, but people may have relied upon it. To get this 637 behavior back, you can .include /etc/src.conf from /etc/make.conf 638 (which is still global and isn't changed). This also changes the 639 behavior of incremental builds inside the tree of individual 640 directories. Set MAKESYSPATH to ".../share/mk" to do that. 641 Although this has survived make universe and some upgrade scenarios, 642 other upgrade scenarios may have broken. At least one form of 643 temporary breakage was fixed with MAKESYSPATH settings for buildworld 644 as well... In cases where MAKESYSPATH isn't working with this 645 setting, you'll need to set it to the full path to your tree. 646 647 One side effect of all this cleaning up is that bsd.compiler.mk 648 is no longer implicitly included by bsd.own.mk. If you wish to 649 use COMPILER_TYPE, you must now explicitly include bsd.compiler.mk 650 as well. 651 65220140430: 653 The lindev device has been removed since /dev/full has been made a 654 standard device. __FreeBSD_version has been bumped. 655 65620140424: 657 The knob WITHOUT_VI was added to the base system, which controls 658 building ex(1), vi(1), etc. Older releases of FreeBSD required ex(1) 659 in order to reorder files share/termcap and didn't build ex(1) as a 660 build tool, so building/installing with WITH_VI is highly advised for 661 build hosts for older releases. 662 663 This issue has been fixed in stable/9 and stable/10 in r277022 and 664 r276991, respectively. 665 66620140418: 667 The YES_HESIOD knob has been removed. It has been obsolete for 668 a decade. Please move to using WITH_HESIOD instead or your builds 669 will silently lack HESIOD. 670 67120140405: 672 The uart(4) driver has been changed with respect to its handling 673 of the low-level console. Previously the uart(4) driver prevented 674 any process from changing the baudrate or the CLOCAL and HUPCL 675 control flags. By removing the restrictions, operators can make 676 changes to the serial console port without having to reboot. 677 However, when getty(8) is started on the serial device that is 678 associated with the low-level console, a misconfigured terminal 679 line in /etc/ttys will now have a real impact. 680 Before upgrading the kernel, make sure that /etc/ttys has the 681 serial console device configured as 3wire without baudrate to 682 preserve the previous behaviour. E.g: 683 ttyu0 "/usr/libexec/getty 3wire" vt100 on secure 684 68520140306: 686 Support for libwrap (TCP wrappers) in rpcbind was disabled by default 687 to improve performance. To re-enable it, if needed, run rpcbind 688 with command line option -W. 689 69020140226: 691 Switched back to the GPL dtc compiler due to updates in the upstream 692 dts files not being supported by the BSDL dtc compiler. You will need 693 to rebuild your kernel toolchain to pick up the new compiler. Core dumps 694 may result while building dtb files during a kernel build if you fail 695 to do so. Set WITHOUT_GPL_DTC if you require the BSDL compiler. 696 69720140216: 698 Clang and llvm have been upgraded to 3.4 release. 699 70020140216: 701 The nve(4) driver has been removed. Please use the nfe(4) driver 702 for NVIDIA nForce MCP Ethernet adapters instead. 703 70420140212: 705 An ABI incompatibility crept into the libc++ 3.4 import in r261283. 706 This could cause certain C++ applications using shared libraries built 707 against the previous version of libc++ to crash. The incompatibility 708 has now been fixed, but any C++ applications or shared libraries built 709 between r261283 and r261801 should be recompiled. 710 71120140204: 712 OpenSSH will now ignore errors caused by kernel lacking of Capsicum 713 capability mode support. Please note that enabling the feature in 714 kernel is still highly recommended. 715 71620140131: 717 OpenSSH is now built with sandbox support, and will use sandbox as 718 the default privilege separation method. This requires Capsicum 719 capability mode support in kernel. 720 72120140128: 722 The libelf and libdwarf libraries have been updated to newer 723 versions from upstream. Shared library version numbers for 724 these two libraries were bumped. Any ports or binaries 725 requiring these two libraries should be recompiled. 726 __FreeBSD_version is bumped to 1100006. 727 72820140110: 729 If a Makefile in a tests/ directory was auto-generating a Kyuafile 730 instead of providing an explicit one, this would prevent such 731 Makefile from providing its own Kyuafile in the future during 732 NO_CLEAN builds. This has been fixed in the Makefiles but manual 733 intervention is needed to clean an objdir if you use NO_CLEAN: 734 # find /usr/obj -name Kyuafile | xargs rm -f 735 73620131213: 737 The behavior of gss_pseudo_random() for the krb5 mechanism 738 has changed, for applications requesting a longer random string 739 than produced by the underlying enctype's pseudo-random() function. 740 In particular, the random string produced from a session key of 741 enctype aes256-cts-hmac-sha1-96 or aes256-cts-hmac-sha1-96 will 742 be different at the 17th octet and later, after this change. 743 The counter used in the PRF+ construction is now encoded as a 744 big-endian integer in accordance with RFC 4402. 745 __FreeBSD_version is bumped to 1100004. 746 74720131108: 748 The WITHOUT_ATF build knob has been removed and its functionality 749 has been subsumed into the more generic WITHOUT_TESTS. If you were 750 using the former to disable the build of the ATF libraries, you 751 should change your settings to use the latter. 752 75320131025: 754 The default version of mtree is nmtree which is obtained from 755 NetBSD. The output is generally the same, but may vary 756 slightly. If you found you need identical output adding 757 "-F freebsd9" to the command line should do the trick. For the 758 time being, the old mtree is available as fmtree. 759 76020131014: 761 libbsdyml has been renamed to libyaml and moved to /usr/lib/private. 762 This will break ports-mgmt/pkg. Rebuild the port, or upgrade to pkg 763 1.1.4_8 and verify bsdyml not linked in, before running "make 764 delete-old-libs": 765 # make -C /usr/ports/ports-mgmt/pkg build deinstall install clean 766 or 767 # pkg install pkg; ldd /usr/local/sbin/pkg | grep bsdyml 768 76920131010: 770 The stable/10 branch has been created in subversion from head 771 revision r256279. 772 77320131010: 774 The rc.d/jail script has been updated to support jail(8) 775 configuration file. The "jail_<jname>_*" rc.conf(5) variables 776 for per-jail configuration are automatically converted to 777 /var/run/jail.<jname>.conf before the jail(8) utility is invoked. 778 This is transparently backward compatible. See below about some 779 incompatibilities and rc.conf(5) manual page for more details. 780 781 These variables are now deprecated in favor of jail(8) configuration 782 file. One can use "rc.d/jail config <jname>" command to generate 783 a jail(8) configuration file in /var/run/jail.<jname>.conf without 784 running the jail(8) utility. The default pathname of the 785 configuration file is /etc/jail.conf and can be specified by 786 using $jail_conf or $jail_<jname>_conf variables. 787 788 Please note that jail_devfs_ruleset accepts an integer at 789 this moment. Please consider to rewrite the ruleset name 790 with an integer. 791 79220130930: 793 BIND has been removed from the base system. If all you need 794 is a local resolver, simply enable and start the local_unbound 795 service instead. Otherwise, several versions of BIND are 796 available in the ports tree. The dns/bind99 port is one example. 797 798 With this change, nslookup(1) and dig(1) are no longer in the base 799 system. Users should instead use host(1) and drill(1) which are 800 in the base system. Alternatively, nslookup and dig can 801 be obtained by installing the dns/bind-tools port. 802 80320130916: 804 With the addition of unbound(8), a new unbound user is now 805 required during installworld. "mergemaster -p" can be used to 806 add the user prior to installworld, as documented in the handbook. 807 80820130911: 809 OpenSSH is now built with DNSSEC support, and will by default 810 silently trust signed SSHFP records. This can be controlled with 811 the VerifyHostKeyDNS client configuration setting. DNSSEC support 812 can be disabled entirely with the WITHOUT_LDNS option in src.conf. 813 81420130906: 815 The GNU Compiler Collection and C++ standard library (libstdc++) 816 are no longer built by default on platforms where clang is the system 817 compiler. You can enable them with the WITH_GCC and WITH_GNUCXX 818 options in src.conf. 819 82020130905: 821 The PROCDESC kernel option is now part of the GENERIC kernel 822 configuration and is required for the rwhod(8) to work. 823 If you are using custom kernel configuration, you should include 824 'options PROCDESC'. 825 82620130905: 827 The API and ABI related to the Capsicum framework was modified 828 in backward incompatible way. The userland libraries and programs 829 have to be recompiled to work with the new kernel. This includes the 830 following libraries and programs, but the whole buildworld is 831 advised: libc, libprocstat, dhclient, tcpdump, hastd, hastctl, 832 kdump, procstat, rwho, rwhod, uniq. 833 83420130903: 835 AES-NI intrinsic support has been added to gcc. The AES-NI module 836 has been updated to use this support. A new gcc is required to build 837 the aesni module on both i386 and amd64. 838 83920130821: 840 The PADLOCK_RNG and RDRAND_RNG kernel options are now devices. 841 Thus "device padlock_rng" and "device rdrand_rng" should be 842 used instead of "options PADLOCK_RNG" & "options RDRAND_RNG". 843 84420130813: 845 WITH_ICONV has been split into two feature sets. WITH_ICONV now 846 enables just the iconv* functionality and is now on by default. 847 WITH_LIBICONV_COMPAT enables the libiconv api and link time 848 compatability. Set WITHOUT_ICONV to build the old way. 849 If you have been using WITH_ICONV before, you will very likely 850 need to turn on WITH_LIBICONV_COMPAT. 851 85220130806: 853 INVARIANTS option now enables DEBUG for code with OpenSolaris and 854 Illumos origin, including ZFS. If you have INVARIANTS in your 855 kernel configuration, then there is no need to set DEBUG or ZFS_DEBUG 856 explicitly. 857 DEBUG used to enable witness(9) tracking of OpenSolaris (mostly ZFS) 858 locks if WITNESS option was set. Because that generated a lot of 859 witness(9) reports and all of them were believed to be false 860 positives, this is no longer done. New option OPENSOLARIS_WITNESS 861 can be used to achieve the previous behavior. 862 86320130806: 864 Timer values in IPv6 data structures now use time_uptime instead 865 of time_second. Although this is not a user-visible functional 866 change, userland utilities which directly use them---ndp(8), 867 rtadvd(8), and rtsold(8) in the base system---need to be updated 868 to r253970 or later. 869 87020130802: 871 find -delete can now delete the pathnames given as arguments, 872 instead of only files found below them or if the pathname did 873 not contain any slashes. Formerly, the following error message 874 would result: 875 876 find: -delete: <path>: relative path potentially not safe 877 878 Deleting the pathnames given as arguments can be prevented 879 without error messages using -mindepth 1 or by changing 880 directory and passing "." as argument to find. This works in the 881 old as well as the new version of find. 882 88320130726: 884 Behavior of devfs rules path matching has been changed. 885 Pattern is now always matched against fully qualified devfs 886 path and slash characters must be explicitly matched by 887 slashes in pattern (FNM_PATHNAME). Rulesets involving devfs 888 subdirectories must be reviewed. 889 89020130716: 891 The default ARM ABI has changed to the ARM EABI. The old ABI is 892 incompatible with the ARM EABI and all programs and modules will 893 need to be rebuilt to work with a new kernel. 894 895 To keep using the old ABI ensure the WITHOUT_ARM_EABI knob is set. 896 897 NOTE: Support for the old ABI will be removed in the future and 898 users are advised to upgrade. 899 90020130709: 901 pkg_install has been disconnected from the build if you really need it 902 you should add WITH_PKGTOOLS in your src.conf(5). 903 90420130709: 905 Most of network statistics structures were changed to be able 906 keep 64-bits counters. Thus all tools, that work with networking 907 statistics, must be rebuilt (netstat(1), bsnmpd(1), etc.) 908 90920130618: 910 Fix a bug that allowed a tracing process (e.g. gdb) to write 911 to a memory-mapped file in the traced process's address space 912 even if neither the traced process nor the tracing process had 913 write access to that file. 914 91520130615: 916 CVS has been removed from the base system. An exact copy 917 of the code is available from the devel/cvs port. 918 91920130613: 920 Some people report the following error after the switch to bmake: 921 922 make: illegal option -- J 923 usage: make [-BPSXeiknpqrstv] [-C directory] [-D variable] 924 ... 925 *** [buildworld] Error code 2 926 927 this likely due to an old instance of make in 928 ${MAKEPATH} (${MAKEOBJDIRPREFIX}${.CURDIR}/make.${MACHINE}) 929 which src/Makefile will use that blindly, if it exists, so if 930 you see the above error: 931 932 rm -rf `make -V MAKEPATH` 933 934 should resolve it. 935 93620130516: 937 Use bmake by default. 938 Whereas before one could choose to build with bmake via 939 -DWITH_BMAKE one must now use -DWITHOUT_BMAKE to use the old 940 make. The goal is to remove these knobs for 10-RELEASE. 941 942 It is worth noting that bmake (like gmake) treats the command 943 line as the unit of failure, rather than statements within the 944 command line. Thus '(cd some/where && dosomething)' is safer 945 than 'cd some/where; dosomething'. The '()' allows consistent 946 behavior in parallel build. 947 94820130429: 949 Fix a bug that allows NFS clients to issue READDIR on files. 950 95120130426: 952 The WITHOUT_IDEA option has been removed because 953 the IDEA patent expired. 954 95520130426: 956 The sysctl which controls TRIM support under ZFS has been renamed 957 from vfs.zfs.trim_disable -> vfs.zfs.trim.enabled and has been 958 enabled by default. 959 96020130425: 961 The mergemaster command now uses the default MAKEOBJDIRPREFIX 962 rather than creating it's own in the temporary directory in 963 order allow access to bootstrapped versions of tools such as 964 install and mtree. When upgrading from version of FreeBSD where 965 the install command does not support -l, you will need to 966 install a new mergemaster command if mergemaster -p is required. 967 This can be accomplished with the command (cd src/usr.sbin/mergemaster 968 && make install). 969 97020130404: 971 Legacy ATA stack, disabled and replaced by new CAM-based one since 972 FreeBSD 9.0, completely removed from the sources. Kernel modules 973 atadisk and atapi*, user-level tools atacontrol and burncd are 974 removed. Kernel option `options ATA_CAM` is now permanently enabled 975 and removed. 976 97720130319: 978 SOCK_CLOEXEC and SOCK_NONBLOCK flags have been added to socket(2) 979 and socketpair(2). Software, in particular Kerberos, may 980 automatically detect and use these during building. The resulting 981 binaries will not work on older kernels. 982 98320130308: 984 CTL_DISABLE has also been added to the sparc64 GENERIC (for further 985 information, see the respective 20130304 entry). 986 98720130304: 988 Recent commits to callout(9) changed the size of struct callout, 989 so the KBI is probably heavily disturbed. Also, some functions 990 in callout(9)/sleep(9)/sleepqueue(9)/condvar(9) KPIs were replaced 991 by macros. Every kernel module using it won't load, so rebuild 992 is requested. 993 994 The ctl device has been re-enabled in GENERIC for i386 and amd64, 995 but does not initialize by default (because of the new CTL_DISABLE 996 option) to save memory. To re-enable it, remove the CTL_DISABLE 997 option from the kernel config file or set kern.cam.ctl.disable=0 998 in /boot/loader.conf. 999 100020130301: 1001 The ctl device has been disabled in GENERIC for i386 and amd64. 1002 This was done due to the extra memory being allocated at system 1003 initialisation time by the ctl driver which was only used if 1004 a CAM target device was created. This makes a FreeBSD system 1005 unusable on 128MB or less of RAM. 1006 100720130208: 1008 A new compression method (lz4) has been merged to -HEAD. Please 1009 refer to zpool-features(7) for more information. 1010 1011 Please refer to the "ZFS notes" section of this file for information 1012 on upgrading boot ZFS pools. 1013 101420130129: 1015 A BSD-licensed patch(1) variant has been added and is installed 1016 as bsdpatch, being the GNU version the default patch. 1017 To inverse the logic and use the BSD-licensed one as default, 1018 while having the GNU version installed as gnupatch, rebuild 1019 and install world with the WITH_BSD_PATCH knob set. 1020 102120130121: 1022 Due to the use of the new -l option to install(1) during build 1023 and install, you must take care not to directly set the INSTALL 1024 make variable in your /etc/make.conf, /etc/src.conf, or on the 1025 command line. If you wish to use the -C flag for all installs 1026 you may be able to add INSTALL+=-C to /etc/make.conf or 1027 /etc/src.conf. 1028 102920130118: 1030 The install(1) option -M has changed meaning and now takes an 1031 argument that is a file or path to append logs to. In the 1032 unlikely event that -M was the last option on the command line 1033 and the command line contained at least two files and a target 1034 directory the first file will have logs appended to it. The -M 1035 option served little practical purpose in the last decade so its 1036 use is expected to be extremely rare. 1037 103820121223: 1039 After switching to Clang as the default compiler some users of ZFS 1040 on i386 systems started to experience stack overflow kernel panics. 1041 Please consider using 'options KSTACK_PAGES=4' in such configurations. 1042 104320121222: 1044 GEOM_LABEL now mangles label names read from file system metadata. 1045 Mangling affect labels containing spaces, non-printable characters, 1046 '%' or '"'. Device names in /etc/fstab and other places may need to 1047 be updated. 1048 104920121217: 1050 By default, only the 10 most recent kernel dumps will be saved. To 1051 restore the previous behaviour (no limit on the number of kernel dumps 1052 stored in the dump directory) add the following line to /etc/rc.conf: 1053 1054 savecore_flags="" 1055 105620121201: 1057 With the addition of auditdistd(8), a new auditdistd user is now 1058 required during installworld. "mergemaster -p" can be used to 1059 add the user prior to installworld, as documented in the handbook. 1060 106120121117: 1062 The sin6_scope_id member variable in struct sockaddr_in6 is now 1063 filled by the kernel before passing the structure to the userland via 1064 sysctl or routing socket. This means the KAME-specific embedded scope 1065 id in sin6_addr.s6_addr[2] is always cleared in userland application. 1066 This behavior can be controlled by net.inet6.ip6.deembed_scopeid. 1067 __FreeBSD_version is bumped to 1000025. 1068 106920121105: 1070 On i386 and amd64 systems WITH_CLANG_IS_CC is now the default. 1071 This means that the world and kernel will be compiled with clang 1072 and that clang will be installed as /usr/bin/cc, /usr/bin/c++, 1073 and /usr/bin/cpp. To disable this behavior and revert to building 1074 with gcc, compile with WITHOUT_CLANG_IS_CC. Really old versions 1075 of current may need to bootstrap WITHOUT_CLANG first if the clang 1076 build fails (its compatibility window doesn't extend to the 9 stable 1077 branch point). 1078 107920121102: 1080 The IPFIREWALL_FORWARD kernel option has been removed. Its 1081 functionality now turned on by default. 1082 108320121023: 1084 The ZERO_COPY_SOCKET kernel option has been removed and 1085 split into SOCKET_SEND_COW and SOCKET_RECV_PFLIP. 1086 NB: SOCKET_SEND_COW uses the VM page based copy-on-write 1087 mechanism which is not safe and may result in kernel crashes. 1088 NB: The SOCKET_RECV_PFLIP mechanism is useless as no current 1089 driver supports disposeable external page sized mbuf storage. 1090 Proper replacements for both zero-copy mechanisms are under 1091 consideration and will eventually lead to complete removal 1092 of the two kernel options. 1093 109420121023: 1095 The IPv4 network stack has been converted to network byte 1096 order. The following modules need to be recompiled together 1097 with kernel: carp(4), divert(4), gif(4), siftr(4), gre(4), 1098 pf(4), ipfw(4), ng_ipfw(4), stf(4). 1099 110020121022: 1101 Support for non-MPSAFE filesystems was removed from VFS. The 1102 VFS_VERSION was bumped, all filesystem modules shall be 1103 recompiled. 1104 110520121018: 1106 All the non-MPSAFE filesystems have been disconnected from 1107 the build. The full list includes: codafs, hpfs, ntfs, nwfs, 1108 portalfs, smbfs, xfs. 1109 111020121016: 1111 The interface cloning API and ABI has changed. The following 1112 modules need to be recompiled together with kernel: 1113 ipfw(4), pfsync(4), pflog(4), usb(4), wlan(4), stf(4), 1114 vlan(4), disc(4), edsc(4), if_bridge(4), gif(4), tap(4), 1115 faith(4), epair(4), enc(4), tun(4), if_lagg(4), gre(4). 1116 111720121015: 1118 The sdhci driver was split in two parts: sdhci (generic SD Host 1119 Controller logic) and sdhci_pci (actual hardware driver). 1120 No kernel config modifications are required, but if you 1121 load sdhc as a module you must switch to sdhci_pci instead. 1122 112320121014: 1124 Import the FUSE kernel and userland support into base system. 1125 112620121013: 1127 The GNU sort(1) program has been removed since the BSD-licensed 1128 sort(1) has been the default for quite some time and no serious 1129 problems have been reported. The corresponding WITH_GNU_SORT 1130 knob has also gone. 1131 113220121006: 1133 The pfil(9) API/ABI for AF_INET family has been changed. Packet 1134 filtering modules: pf(4), ipfw(4), ipfilter(4) need to be recompiled 1135 with new kernel. 1136 113720121001: 1138 The net80211(4) ABI has been changed to allow for improved driver 1139 PS-POLL and power-save support. All wireless drivers need to be 1140 recompiled to work with the new kernel. 1141 114220120913: 1143 The random(4) support for the VIA hardware random number 1144 generator (`PADLOCK') is no longer enabled unconditionally. 1145 Add the padlock_rng device in the custom kernel config if 1146 needed. The GENERIC kernels on i386 and amd64 do include the 1147 device, so the change only affects the custom kernel 1148 configurations. 1149 115020120908: 1151 The pf(4) packet filter ABI has been changed. pfctl(8) and 1152 snmp_pf module need to be recompiled to work with new kernel. 1153 115420120828: 1155 A new ZFS feature flag "com.delphix:empty_bpobj" has been merged 1156 to -HEAD. Pools that have empty_bpobj in active state can not be 1157 imported read-write with ZFS implementations that do not support 1158 this feature. For more information read the zpool-features(5) 1159 manual page. 1160 116120120727: 1162 The sparc64 ZFS loader has been changed to no longer try to auto- 1163 detect ZFS providers based on diskN aliases but now requires these 1164 to be explicitly listed in the OFW boot-device environment variable. 1165 116620120712: 1167 The OpenSSL has been upgraded to 1.0.1c. Any binaries requiring 1168 libcrypto.so.6 or libssl.so.6 must be recompiled. Also, there are 1169 configuration changes. Make sure to merge /etc/ssl/openssl.cnf. 1170 117120120712: 1172 The following sysctls and tunables have been renamed for consistency 1173 with other variables: 1174 kern.cam.da.da_send_ordered -> kern.cam.da.send_ordered 1175 kern.cam.ada.ada_send_ordered -> kern.cam.ada.send_ordered 1176 117720120628: 1178 The sort utility has been replaced with BSD sort. For now, GNU sort 1179 is also available as "gnusort" or the default can be set back to 1180 GNU sort by setting WITH_GNU_SORT. In this case, BSD sort will be 1181 installed as "bsdsort". 1182 118320120611: 1184 A new version of ZFS (pool version 5000) has been merged to -HEAD. 1185 Starting with this version the old system of ZFS pool versioning 1186 is superseded by "feature flags". This concept enables forward 1187 compatibility against certain future changes in functionality of ZFS 1188 pools. The first read-only compatible "feature flag" for ZFS pools 1189 is named "com.delphix:async_destroy". For more information 1190 read the new zpool-features(5) manual page. 1191 Please refer to the "ZFS notes" section of this file for information 1192 on upgrading boot ZFS pools. 1193 119420120417: 1195 The malloc(3) implementation embedded in libc now uses sources imported 1196 as contrib/jemalloc. The most disruptive API change is to 1197 /etc/malloc.conf. If your system has an old-style /etc/malloc.conf, 1198 delete it prior to installworld, and optionally re-create it using the 1199 new format after rebooting. See malloc.conf(5) for details 1200 (specifically the TUNING section and the "opt.*" entries in the MALLCTL 1201 NAMESPACE section). 1202 120320120328: 1204 Big-endian MIPS TARGET_ARCH values no longer end in "eb". mips64eb 1205 is now spelled mips64. mipsn32eb is now spelled mipsn32. mipseb is 1206 now spelled mips. This is to aid compatibility with third-party 1207 software that expects this naming scheme in uname(3). Little-endian 1208 settings are unchanged. If you are updating a big-endian mips64 machine 1209 from before this change, you may need to set MACHINE_ARCH=mips64 in 1210 your environment before the new build system will recognize your machine. 1211 121220120306: 1213 Disable by default the option VFS_ALLOW_NONMPSAFE for all supported 1214 platforms. 1215 121620120229: 1217 Now unix domain sockets behave "as expected" on nullfs(5). Previously 1218 nullfs(5) did not pass through all behaviours to the underlying layer, 1219 as a result if we bound to a socket on the lower layer we could connect 1220 only to the lower path; if we bound to the upper layer we could connect 1221 only to the upper path. The new behavior is one can connect to both the 1222 lower and the upper paths regardless what layer path one binds to. 1223 122420120211: 1225 The getifaddrs upgrade path broken with 20111215 has been restored. 1226 If you have upgraded in between 20111215 and 20120209 you need to 1227 recompile libc again with your kernel. You still need to recompile 1228 world to be able to configure CARP but this restriction already 1229 comes from 20111215. 1230 123120120114: 1232 The set_rcvar() function has been removed from /etc/rc.subr. All 1233 base and ports rc.d scripts have been updated, so if you have a 1234 port installed with a script in /usr/local/etc/rc.d you can either 1235 hand-edit the rcvar= line, or reinstall the port. 1236 1237 An easy way to handle the mass-update of /etc/rc.d: 1238 rm /etc/rc.d/* && mergemaster -i 1239 124020120109: 1241 panic(9) now stops other CPUs in the SMP systems, disables interrupts 1242 on the current CPU and prevents other threads from running. 1243 This behavior can be reverted using the kern.stop_scheduler_on_panic 1244 tunable/sysctl. 1245 The new behavior can be incompatible with kern.sync_on_panic. 1246 124720111215: 1248 The carp(4) facility has been changed significantly. Configuration 1249 of the CARP protocol via ifconfig(8) has changed, as well as format 1250 of CARP events submitted to devd(8) has changed. See manual pages 1251 for more information. The arpbalance feature of carp(4) is currently 1252 not supported anymore. 1253 1254 Size of struct in_aliasreq, struct in6_aliasreq has changed. User 1255 utilities using SIOCAIFADDR, SIOCAIFADDR_IN6, e.g. ifconfig(8), 1256 need to be recompiled. 1257 125820111122: 1259 The acpi_wmi(4) status device /dev/wmistat has been renamed to 1260 /dev/wmistat0. 1261 126220111108: 1263 The option VFS_ALLOW_NONMPSAFE option has been added in order to 1264 explicitely support non-MPSAFE filesystems. 1265 It is on by default for all supported platform at this present 1266 time. 1267 126820111101: 1269 The broken amd(4) driver has been replaced with esp(4) in the amd64, 1270 i386 and pc98 GENERIC kernel configuration files. 1271 127220110930: 1273 sysinstall has been removed 1274 127520110923: 1276 The stable/9 branch created in subversion. This corresponds to the 1277 RELENG_9 branch in CVS. 1278 1279COMMON ITEMS: 1280 1281 General Notes 1282 ------------- 1283 Avoid using make -j when upgrading. While generally safe, there are 1284 sometimes problems using -j to upgrade. If your upgrade fails with 1285 -j, please try again without -j. From time to time in the past there 1286 have been problems using -j with buildworld and/or installworld. This 1287 is especially true when upgrading between "distant" versions (eg one 1288 that cross a major release boundary or several minor releases, or when 1289 several months have passed on the -current branch). 1290 1291 Sometimes, obscure build problems are the result of environment 1292 poisoning. This can happen because the make utility reads its 1293 environment when searching for values for global variables. To run 1294 your build attempts in an "environmental clean room", prefix all make 1295 commands with 'env -i '. See the env(1) manual page for more details. 1296 1297 When upgrading from one major version to another it is generally best 1298 to upgrade to the latest code in the currently installed branch first, 1299 then do an upgrade to the new branch. This is the best-tested upgrade 1300 path, and has the highest probability of being successful. Please try 1301 this approach before reporting problems with a major version upgrade. 1302 1303 When upgrading a live system, having a root shell around before 1304 installing anything can help undo problems. Not having a root shell 1305 around can lead to problems if pam has changed too much from your 1306 starting point to allow continued authentication after the upgrade. 1307 1308 This file should be read as a log of events. When a later event changes 1309 information of a prior event, the prior event should not be deleted. 1310 Instead, a pointer to the entry with the new information should be 1311 placed in the old entry. Readers of this file should also sanity check 1312 older entries before relying on them blindly. Authors of new entries 1313 should write them with this in mind. 1314 1315 ZFS notes 1316 --------- 1317 When upgrading the boot ZFS pool to a new version, always follow 1318 these two steps: 1319 1320 1.) recompile and reinstall the ZFS boot loader and boot block 1321 (this is part of "make buildworld" and "make installworld") 1322 1323 2.) update the ZFS boot block on your boot drive 1324 1325 The following example updates the ZFS boot block on the first 1326 partition (freebsd-boot) of a GPT partitioned drive ada0: 1327 "gpart bootcode -p /boot/gptzfsboot -i 1 ada0" 1328 1329 Non-boot pools do not need these updates. 1330 1331 To build a kernel 1332 ----------------- 1333 If you are updating from a prior version of FreeBSD (even one just 1334 a few days old), you should follow this procedure. It is the most 1335 failsafe as it uses a /usr/obj tree with a fresh mini-buildworld, 1336 1337 make kernel-toolchain 1338 make -DALWAYS_CHECK_MAKE buildkernel KERNCONF=YOUR_KERNEL_HERE 1339 make -DALWAYS_CHECK_MAKE installkernel KERNCONF=YOUR_KERNEL_HERE 1340 1341 To test a kernel once 1342 --------------------- 1343 If you just want to boot a kernel once (because you are not sure 1344 if it works, or if you want to boot a known bad kernel to provide 1345 debugging information) run 1346 make installkernel KERNCONF=YOUR_KERNEL_HERE KODIR=/boot/testkernel 1347 nextboot -k testkernel 1348 1349 To just build a kernel when you know that it won't mess you up 1350 -------------------------------------------------------------- 1351 This assumes you are already running a CURRENT system. Replace 1352 ${arch} with the architecture of your machine (e.g. "i386", 1353 "arm", "amd64", "ia64", "pc98", "sparc64", "powerpc", "mips", etc). 1354 1355 cd src/sys/${arch}/conf 1356 config KERNEL_NAME_HERE 1357 cd ../compile/KERNEL_NAME_HERE 1358 make depend 1359 make 1360 make install 1361 1362 If this fails, go to the "To build a kernel" section. 1363 1364 To rebuild everything and install it on the current system. 1365 ----------------------------------------------------------- 1366 # Note: sometimes if you are running current you gotta do more than 1367 # is listed here if you are upgrading from a really old current. 1368 1369 <make sure you have good level 0 dumps> 1370 make buildworld 1371 make kernel KERNCONF=YOUR_KERNEL_HERE 1372 [1] 1373 <reboot in single user> [3] 1374 mergemaster -Fp [5] 1375 make installworld 1376 mergemaster -Fi [4] 1377 make delete-old [6] 1378 <reboot> 1379 1380 To cross-install current onto a separate partition 1381 -------------------------------------------------- 1382 # In this approach we use a separate partition to hold 1383 # current's root, 'usr', and 'var' directories. A partition 1384 # holding "/", "/usr" and "/var" should be about 2GB in 1385 # size. 1386 1387 <make sure you have good level 0 dumps> 1388 <boot into -stable> 1389 make buildworld 1390 make buildkernel KERNCONF=YOUR_KERNEL_HERE 1391 <maybe newfs current's root partition> 1392 <mount current's root partition on directory ${CURRENT_ROOT}> 1393 make installworld DESTDIR=${CURRENT_ROOT} -DDB_FROM_SRC 1394 make distribution DESTDIR=${CURRENT_ROOT} # if newfs'd 1395 make installkernel KERNCONF=YOUR_KERNEL_HERE DESTDIR=${CURRENT_ROOT} 1396 cp /etc/fstab ${CURRENT_ROOT}/etc/fstab # if newfs'd 1397 <edit ${CURRENT_ROOT}/etc/fstab to mount "/" from the correct partition> 1398 <reboot into current> 1399 <do a "native" rebuild/install as described in the previous section> 1400 <maybe install compatibility libraries from ports/misc/compat*> 1401 <reboot> 1402 1403 1404 To upgrade in-place from stable to current 1405 ---------------------------------------------- 1406 <make sure you have good level 0 dumps> 1407 make buildworld [9] 1408 make kernel KERNCONF=YOUR_KERNEL_HERE [8] 1409 [1] 1410 <reboot in single user> [3] 1411 mergemaster -Fp [5] 1412 make installworld 1413 mergemaster -Fi [4] 1414 make delete-old [6] 1415 <reboot> 1416 1417 Make sure that you've read the UPDATING file to understand the 1418 tweaks to various things you need. At this point in the life 1419 cycle of current, things change often and you are on your own 1420 to cope. The defaults can also change, so please read ALL of 1421 the UPDATING entries. 1422 1423 Also, if you are tracking -current, you must be subscribed to 1424 freebsd-current@freebsd.org. Make sure that before you update 1425 your sources that you have read and understood all the recent 1426 messages there. If in doubt, please track -stable which has 1427 much fewer pitfalls. 1428 1429 [1] If you have third party modules, such as vmware, you 1430 should disable them at this point so they don't crash your 1431 system on reboot. 1432 1433 [3] From the bootblocks, boot -s, and then do 1434 fsck -p 1435 mount -u / 1436 mount -a 1437 cd src 1438 adjkerntz -i # if CMOS is wall time 1439 Also, when doing a major release upgrade, it is required that 1440 you boot into single user mode to do the installworld. 1441 1442 [4] Note: This step is non-optional. Failure to do this step 1443 can result in a significant reduction in the functionality of the 1444 system. Attempting to do it by hand is not recommended and those 1445 that pursue this avenue should read this file carefully, as well 1446 as the archives of freebsd-current and freebsd-hackers mailing lists 1447 for potential gotchas. The -U option is also useful to consider. 1448 See mergemaster(8) for more information. 1449 1450 [5] Usually this step is a noop. However, from time to time 1451 you may need to do this if you get unknown user in the following 1452 step. It never hurts to do it all the time. You may need to 1453 install a new mergemaster (cd src/usr.sbin/mergemaster && make 1454 install) after the buildworld before this step if you last updated 1455 from current before 20130425 or from -stable before 20130430. 1456 1457 [6] This only deletes old files and directories. Old libraries 1458 can be deleted by "make delete-old-libs", but you have to make 1459 sure that no program is using those libraries anymore. 1460 1461 [8] In order to have a kernel that can run the 4.x binaries needed to 1462 do an installworld, you must include the COMPAT_FREEBSD4 option in 1463 your kernel. Failure to do so may leave you with a system that is 1464 hard to boot to recover. A similar kernel option COMPAT_FREEBSD5 is 1465 required to run the 5.x binaries on more recent kernels. And so on 1466 for COMPAT_FREEBSD6 and COMPAT_FREEBSD7. 1467 1468 Make sure that you merge any new devices from GENERIC since the 1469 last time you updated your kernel config file. 1470 1471 [9] When checking out sources, you must include the -P flag to have 1472 cvs prune empty directories. 1473 1474 If CPUTYPE is defined in your /etc/make.conf, make sure to use the 1475 "?=" instead of the "=" assignment operator, so that buildworld can 1476 override the CPUTYPE if it needs to. 1477 1478 MAKEOBJDIRPREFIX must be defined in an environment variable, and 1479 not on the command line, or in /etc/make.conf. buildworld will 1480 warn if it is improperly defined. 1481FORMAT: 1482 1483This file contains a list, in reverse chronological order, of major 1484breakages in tracking -current. It is not guaranteed to be a complete 1485list of such breakages, and only contains entries since September 23, 2011. 1486If you need to see UPDATING entries from before that date, you will need 1487to fetch an UPDATING file from an older FreeBSD release. 1488 1489Copyright information: 1490 1491Copyright 1998-2009 M.
