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 3420160330: 35 The FAST_DEPEND build option has been removed and its functionality is 36 now the one true way. The old mkdep(1) style of 'make depend' has 37 been removed. See 20160311 for further details. 38 3920160317: 40 Resource range types have grown from unsigned long to uintmax_t. All 41 drivers, and anything using libdevinfo, need to be recompiled. 42 4320160311: 44 WITH_FAST_DEPEND is now enabled by default for in-tree and out-of-tree 45 builds. It no longer runs mkdep(1) during 'make depend', and the 46 'make depend' stage can safely be skipped now as it is auto ran 47 when building 'make all' and will generate all SRCS and DPSRCS before 48 building anything else. Dependencies are gathered at compile time with 49 -MF flags kept in separate .depend files per object file. Users should 50 run 'make cleandepend' once if using -DNO_CLEAN to clean out older 51 stale .depend files. 52 5320160306: 54 On amd64, clang 3.8.0 can now insert sections of type AMD64_UNWIND into 55 kernel modules. Therefore, if you load any kernel modules at boot time, 56 please install the boot loaders after you install the kernel, but before 57 rebooting, e.g.: 58 59 make buildworld 60 make kernel KERNCONF=YOUR_KERNEL_HERE 61 make -C sys/boot install 62 <reboot in single user> 63 64 Then follow the usual steps, described in the General Notes section, 65 below. 66 6720160305: 68 Clang, llvm, lldb and compiler-rt have been upgraded to 3.8.0. Please 69 see the 20141231 entry below for information about prerequisites and 70 upgrading, if you are not already using clang 3.5.0 or higher. 71 7220160301: 73 The AIO subsystem is now a standard part of the kernel. The 74 VFS_AIO kernel option and aio.ko kernel module have been removed. 75 Due to stability concerns, asynchronous I/O requests are only 76 permitted on sockets and raw disks by default. To enable 77 asynchronous I/O requests on all file types, set the 78 vfs.aio.enable_unsafe sysctl to a non-zero value. 79 8020160226: 81 The ELF object manipulation tool objcopy is now provided by the 82 ELF Tool Chain project rather than by GNU binutils. It should be a 83 drop-in replacement, with the addition of arm64 support. The 84 (temporary) src.conf knob WITHOUT_ELFCOPY_AS_OBJCOPY knob may be set 85 to obtain the GNU version if necessary. 86 8720160129: 88 Building ZFS pools on top of zvols is prohibited by default. That 89 feature has never worked safely; it's always been prone to deadlocks. 90 Using a zvol as the backing store for a VM guest's virtual disk will 91 still work, even if the guest is using ZFS. Legacy behavior can be 92 restored by setting vfs.zfs.vol.recursive=1. 93 9420160119: 95 The NONE and HPN patches has been removed from OpenSSH. They are 96 still available in the security/openssh-portable port. 97 9820160113: 99 With the addition of ypldap(8), a new _ypldap user is now required 100 during installworld. "mergemaster -p" can be used to add the user 101 prior to installworld, as documented in the handbook. 102 10320151216: 104 The tftp loader (pxeboot) now uses the option root-path directive. As a 105 consequence it no longer looks for a pxeboot.4th file on the tftp 106 server. Instead it uses the regular /boot infrastructure as with the 107 other loaders. 108 10920151211: 110 The code to start recording plug and play data into the modules has 111 been committed. While the old tools will properly build a new kernel, 112 a number of warnings about "unknown metadata record 4" will be produced 113 for an older kldxref. To avoid such warnings, make sure to rebuild 114 the kernel toolchain (or world). Make sure that you have r292078 or 115 later when trying to build 292077 or later before rebuilding. 116 11720151207: 118 Debug data files are now built by default with 'make buildworld' and 119 installed with 'make installworld'. This facilitates debugging but 120 requires more disk space both during the build and for the installed 121 world. Debug files may be disabled by setting WITHOUT_DEBUG_FILES=yes 122 in src.conf(5). 123 12420151130: 125 r291527 changed the internal interface between the nfsd.ko and 126 nfscommon.ko modules. As such, they must both be upgraded to-gether. 127 __FreeBSD_version has been bumped because of this. 128 12920151108: 130 Add support for unicode collation strings leads to a change of 131 order of files listed by ls(1) for example. To get back to the old 132 behaviour, set LC_COLLATE environment variable to "C". 133 134 Databases administrators will need to reindex their databases given 135 collation results will be different. 136 137 Due to a bug in install(1) it is recommended to remove the ancient 138 locales before running make installworld. 139 140 rm -rf /usr/share/locale/* 141 14220151030: 143 The OpenSSL has been upgraded to 1.0.2d. Any binaries requiring 144 libcrypto.so.7 or libssl.so.7 must be recompiled. 145 14620151020: 147 Qlogic 24xx/25xx firmware images were updated from 5.5.0 to 7.3.0. 148 Kernel modules isp_2400_multi and isp_2500_multi were removed and 149 should be replaced with isp_2400 and isp_2500 modules respectively. 150 15120151017: 152 The build previously allowed using 'make -n' to not recurse into 153 sub-directories while showing what commands would be executed, and 154 'make -n -n' to recursively show commands. Now 'make -n' will recurse 155 and 'make -N' will not. 156 15720151012: 158 If you specify SENDMAIL_MC or SENDMAIL_CF in make.conf, mergemaster 159 and etcupdate will now use this file. A custom sendmail.cf is now 160 updated via this mechanism rather than via installworld. If you had 161 excluded sendmail.cf in mergemaster.rc or etcupdate.conf, you may 162 want to remove the exclusion or change it to "always install". 163 /etc/mail/sendmail.cf is now managed the same way regardless of 164 whether SENDMAIL_MC/SENDMAIL_CF is used. If you are not using 165 SENDMAIL_MC/SENDMAIL_CF there should be no change in behavior. 166 16720151011: 168 Compatibility shims for legacy ATA device names have been removed. 169 It includes ATA_STATIC_ID kernel option, kern.cam.ada.legacy_aliases 170 and kern.geom.raid.legacy_aliases loader tunables, kern.devalias.* 171 environment variables, /dev/ad* and /dev/ar* symbolic links. 172 17320151006: 174 Clang, llvm, lldb, compiler-rt and libc++ have been upgraded to 3.7.0. 175 Please see the 20141231 entry below for information about prerequisites 176 and upgrading, if you are not already using clang 3.5.0 or higher. 177 17820150924: 179 Kernel debug files have been moved to /usr/lib/debug/boot/kernel/, 180 and renamed from .symbols to .debug. This reduces the size requirements 181 on the boot partition or file system and provides consistency with 182 userland debug files. 183 184 When using the supported kernel installation method the 185 /usr/lib/debug/boot/kernel directory will be renamed (to kernel.old) 186 as is done with /boot/kernel. 187 188 Developers wishing to maintain the historical behavior of installing 189 debug files in /boot/kernel/ can set KERN_DEBUGDIR="" in src.conf(5). 190 19120150827: 192 The wireless drivers had undergone changes that remove the 'parent 193 interface' from the ifconfig -l output. The rc.d network scripts 194 used to check presence of a parent interface in the list, so old 195 scripts would fail to start wireless networking. Thus, etcupdate(3) 196 or mergemaster(8) run is required after kernel update, to update your 197 rc.d scripts in /etc. 198 19920150827: 200 pf no longer supports 'scrub fragment crop' or 'scrub fragment drop-ovl' 201 These configurations are now automatically interpreted as 202 'scrub fragment reassemble'. 203 20420150817: 205 Kernel-loadable modules for the random(4) device are back. To use 206 them, the kernel must have 207 208 device random 209 options RANDOM_LOADABLE 210 211 kldload(8) can then be used to load random_fortuna.ko 212 or random_yarrow.ko. Please note that due to the indirect 213 function calls that the loadable modules need to provide, 214 the build-in variants will be slightly more efficient. 215 216 The random(4) kernel option RANDOM_DUMMY has been retired due to 217 unpopularity. It was not all that useful anyway. 218 21920150813: 220 The WITHOUT_ELFTOOLCHAIN_TOOLS src.conf(5) knob has been retired. 221 Control over building the ELF Tool Chain tools is now provided by 222 the WITHOUT_TOOLCHAIN knob. 223 22420150810: 225 The polarity of Pulse Per Second (PPS) capture events with the 226 uart(4) driver has been corrected. Prior to this change the PPS 227 "assert" event corresponded to the trailing edge of a positive PPS 228 pulse and the "clear" event was the leading edge of the next pulse. 229 230 As the width of a PPS pulse in a typical GPS receiver is on the 231 order of 1 millisecond, most users will not notice any significant 232 difference with this change. 233 234 Anyone who has compensated for the historical polarity reversal by 235 configuring a negative offset equal to the pulse width will need to 236 remove that workaround. 237 23820150809: 239 The default group assigned to /dev/dri entries has been changed 240 from 'wheel' to 'video' with the id of '44'. If you want to have 241 access to the dri devices please add yourself to the video group 242 with: 243 244 # pw groupmod video -m $USER 245 24620150806: 247 The menu.rc and loader.rc files will now be replaced during 248 upgrades. Please migrate local changes to menu.rc.local and 249 loader.rc.local instead. 250 25120150805: 252 GNU Binutils versions of addr2line, c++filt, nm, readelf, size, 253 strings and strip have been removed. The src.conf(5) knob 254 WITHOUT_ELFTOOLCHAIN_TOOLS no longer provides the binutils tools. 255 25620150728: 257 As ZFS requires more kernel stack pages than is the default on some 258 architectures e.g. i386, it now warns if KSTACK_PAGES is less than 259 ZFS_MIN_KSTACK_PAGES (which is 4 at the time of writing). 260 261 Please consider using 'options KSTACK_PAGES=X' where X is greater 262 than or equal to ZFS_MIN_KSTACK_PAGES i.e. 4 in such configurations. 263 26420150706: 265 sendmail has been updated to 8.15.2. Starting with FreeBSD 11.0 266 and sendmail 8.15, sendmail uses uncompressed IPv6 addresses by 267 default, i.e., they will not contain "::". For example, instead 268 of ::1, it will be 0:0:0:0:0:0:0:1. This permits a zero subnet 269 to have a more specific match, such as different map entries for 270 IPv6:0:0 vs IPv6:0. This change requires that configuration 271 data (including maps, files, classes, custom ruleset, etc.) must 272 use the same format, so make certain such configuration data is 273 upgrading. As a very simple check search for patterns like 274 'IPv6:[0-9a-fA-F:]*::' and 'IPv6::'. To return to the old 275 behavior, set the m4 option confUSE_COMPRESSED_IPV6_ADDRESSES or 276 the cf option UseCompressedIPv6Addresses. 277 27820150630: 279 The default kernel entropy-processing algorithm is now 280 Fortuna, replacing Yarrow. 281 282 Assuming you have 'device random' in your kernel config 283 file, the configurations allow a kernel option to override 284 this default. You may choose *ONE* of: 285 286 options RANDOM_YARROW # Legacy /dev/random algorithm. 287 options RANDOM_DUMMY # Blocking-only driver. 288 289 If you have neither, you get Fortuna. For most people, 290 read no further, Fortuna will give a /dev/random that works 291 like it always used to, and the difference will be irrelevant. 292 293 If you remove 'device random', you get *NO* kernel-processed 294 entropy at all. This may be acceptable to folks building 295 embedded systems, but has complications. Carry on reading, 296 and it is assumed you know what you need. 297 298 *PLEASE* read random(4) and random(9) if you are in the 299 habit of tweaking kernel configs, and/or if you are a member 300 of the embedded community, wanting specific and not-usual 301 behaviour from your security subsystems. 302 303 NOTE!! If you use RANDOM_DUMMY and/or have no 'device 304 random', you will NOT have a functioning /dev/random, and 305 many cryptographic features will not work, including SSH. 306 You may also find strange behaviour from the random(3) set 307 of library functions, in particular sranddev(3), srandomdev(3) 308 and arc4random(3). The reason for this is that the KERN_ARND 309 sysctl only returns entropy if it thinks it has some to 310 share, and with RANDOM_DUMMY or no 'device random' this 311 will never happen. 312 31320150623: 314 An additional fix for the issue described in the 20150614 sendmail 315 entry below has been been committed in revision 284717. 316 31720150616: 318 FreeBSD's old make (fmake) has been removed from the system. It is 319 available as the devel/fmake port or via pkg install fmake. 320 32120150615: 322 The fix for the issue described in the 20150614 sendmail entry 323 below has been been committed in revision 284436. The work 324 around described in that entry is no longer needed unless the 325 default setting is overridden by a confDH_PARAMETERS configuration 326 setting of '5' or pointing to a 512 bit DH parameter file. 327 32820150614: 329 ALLOW_DEPRECATED_ATF_TOOLS/ATFFILE support has been removed from 330 atf.test.mk (included from bsd.test.mk). Please upgrade devel/atf 331 and devel/kyua to version 0.20+ and adjust any calling code to work 332 with Kyuafile and kyua. 333 33420150614: 335 The import of openssl to address the FreeBSD-SA-15:10.openssl 336 security advisory includes a change which rejects handshakes 337 with DH parameters below 768 bits. sendmail releases prior 338 to 8.15.2 (not yet released), defaulted to a 512 bit 339 DH parameter setting for client connections. To work around 340 this interoperability, sendmail can be configured to use a 341 2048 bit DH parameter by: 342 343 1. Edit /etc/mail/`hostname`.mc 344 2. If a setting for confDH_PARAMETERS does not exist or 345 exists and is set to a string beginning with '5', 346 replace it with '2'. 347 3. If a setting for confDH_PARAMETERS exists and is set to 348 a file path, create a new file with: 349 openssl dhparam -out /path/to/file 2048 350 4. Rebuild the .cf file: 351 cd /etc/mail/; make; make install 352 5. Restart sendmail: 353 cd /etc/mail/; make restart 354 355 A sendmail patch is coming, at which time this file will be 356 updated. 357 35820150604: 359 Generation of legacy formatted entries have been disabled by default 360 in pwd_mkdb(8), as all base system consumers of the legacy formatted 361 entries were converted to use the new format by default when the new, 362 machine independent format have been added and supported since FreeBSD 363 5.x. 364 365 Please see the pwd_mkdb(8) manual page for further details. 366 36720150525: 368 Clang and llvm have been upgraded to 3.6.1 release. Please see the 369 20141231 entry below for information about prerequisites and upgrading, 370 if you are not already using 3.5.0 or higher. 371 37220150521: 373 TI platform code switched to using vendor DTS files and this update 374 may break existing systems running on Beaglebone, Beaglebone Black, 375 and Pandaboard: 376 377 - dtb files should be regenerated/reinstalled. Filenames are the 378 same but content is different now 379 - GPIO addressing was changed, now each GPIO bank (32 pins per bank) 380 has its own /dev/gpiocX device, e.g. pin 121 on /dev/gpioc0 in old 381 addressing scheme is now pin 25 on /dev/gpioc3. 382 - Pandaboard: /etc/ttys should be updated, serial console device is 383 now /dev/ttyu2, not /dev/ttyu0 384 38520150501: 386 soelim(1) from gnu/usr.bin/groff has been replaced by usr.bin/soelim. 387 If you need the GNU extension from groff soelim(1), install groff 388 from package: pkg install groff, or via ports: textproc/groff. 389 39020150423: 391 chmod, chflags, chown and chgrp now affect symlinks in -R mode as 392 defined in symlink(7); previously symlinks were silently ignored. 393 39420150415: 395 The const qualifier has been removed from iconv(3) to comply with 396 POSIX. The ports tree is aware of this from r384038 onwards. 397 39820150416: 399 Libraries specified by LIBADD in Makefiles must have a corresponding 400 DPADD_<lib> variable to ensure correct dependencies. This is now 401 enforced in src.libnames.mk. 402 40320150324: 404 From legacy ata(4) driver was removed support for SATA controllers 405 supported by more functional drivers ahci(4), siis(4) and mvs(4). 406 Kernel modules ataahci and ataadaptec were removed completely, 407 replaced by ahci and mvs modules respectively. 408 40920150315: 410 Clang, llvm and lldb have been upgraded to 3.6.0 release. Please see 411 the 20141231 entry below for information about prerequisites and 412 upgrading, if you are not already using 3.5.0 or higher. 413 41420150307: 415 The 32-bit PowerPC kernel has been changed to a position-independent 416 executable. This can only be booted with a version of loader(8) 417 newer than January 31, 2015, so make sure to update both world and 418 kernel before rebooting. 419 42020150217: 421 If you are running a -CURRENT kernel since r273872 (Oct 30th, 2014), 422 but before r278950, the RNG was not seeded properly. Immediately 423 upgrade the kernel to r278950 or later and regenerate any keys (e.g. 424 ssh keys or openssl keys) that were generated w/ a kernel from that 425 range. This does not affect programs that directly used /dev/random 426 or /dev/urandom. All userland uses of arc4random(3) are affected. 427 42820150210: 429 The autofs(4) ABI was changed in order to restore binary compatibility 430 with 10.1-RELEASE. The automountd(8) daemon needs to be rebuilt to work 431 with the new kernel. 432 43320150131: 434 The powerpc64 kernel has been changed to a position-independent 435 executable. This can only be booted with a new version of loader(8), 436 so make sure to update both world and kernel before rebooting. 437 43820150118: 439 Clang and llvm have been upgraded to 3.5.1 release. This is a bugfix 440 only release, no new features have been added. Please see the 20141231 441 entry below for information about prerequisites and upgrading, if you 442 are not already using 3.5.0. 443 44420150107: 445 ELF tools addr2line, elfcopy (strip), nm, size, and strings are now 446 taken from the ELF Tool Chain project rather than GNU binutils. They 447 should be drop-in replacements, with the addition of arm64 support. 448 The WITHOUT_ELFTOOLCHAIN_TOOLS= knob may be used to obtain the 449 binutils tools, if necessary. See 20150805 for updated information. 450 45120150105: 452 The default Unbound configuration now enables remote control 453 using a local socket. Users who have already enabled the 454 local_unbound service should regenerate their configuration 455 by running "service local_unbound setup" as root. 456 45720150102: 458 The GNU texinfo and GNU info pages have been removed. 459 To be able to view GNU info pages please install texinfo from ports. 460 46120141231: 462 Clang, llvm and lldb have been upgraded to 3.5.0 release. 463 464 As of this release, a prerequisite for building clang, llvm and lldb is 465 a C++11 capable compiler and C++11 standard library. This means that to 466 be able to successfully build the cross-tools stage of buildworld, with 467 clang as the bootstrap compiler, your system compiler or cross compiler 468 should either be clang 3.3 or later, or gcc 4.8 or later, and your 469 system C++ library should be libc++, or libdstdc++ from gcc 4.8 or 470 later. 471 472 On any standard FreeBSD 10.x or 11.x installation, where clang and 473 libc++ are on by default (that is, on x86 or arm), this should work out 474 of the box. 475 476 On 9.x installations where clang is enabled by default, e.g. on x86 and 477 powerpc, libc++ will not be enabled by default, so libc++ should be 478 built (with clang) and installed first. If both clang and libc++ are 479 missing, build clang first, then use it to build libc++. 480 481 On 8.x and earlier installations, upgrade to 9.x first, and then follow 482 the instructions for 9.x above. 483 484 Sparc64 and mips users are unaffected, as they still use gcc 4.2.1 by 485 default, and do not build clang. 486 487 Many embedded systems are resource constrained, and will not be able to 488 build clang in a reasonable time, or in some cases at all. In those 489 cases, cross building bootable systems on amd64 is a workaround. 490 491 This new version of clang introduces a number of new warnings, of which 492 the following are most likely to appear: 493 494 -Wabsolute-value 495 496 This warns in two cases, for both C and C++: 497 * When the code is trying to take the absolute value of an unsigned 498 quantity, which is effectively a no-op, and almost never what was 499 intended. The code should be fixed, if at all possible. If you are 500 sure that the unsigned quantity can be safely cast to signed, without 501 loss of information or undefined behavior, you can add an explicit 502 cast, or disable the warning. 503 504 * When the code is trying to take an absolute value, but the called 505 abs() variant is for the wrong type, which can lead to truncation. 506 If you want to disable the warning instead of fixing the code, please 507 make sure that truncation will not occur, or it might lead to unwanted 508 side-effects. 509 510 -Wtautological-undefined-compare and 511 -Wundefined-bool-conversion 512 513 These warn when C++ code is trying to compare 'this' against NULL, while 514 'this' should never be NULL in well-defined C++ code. However, there is 515 some legacy (pre C++11) code out there, which actively abuses this 516 feature, which was less strictly defined in previous C++ versions. 517 518 Squid and openjdk do this, for example. The warning can be turned off 519 for C++98 and earlier, but compiling the code in C++11 mode might result 520 in unexpected behavior; for example, the parts of the program that are 521 unreachable could be optimized away. 522 52320141222: 524 The old NFS client and server (kernel options NFSCLIENT, NFSSERVER) 525 kernel sources have been removed. The .h files remain, since some 526 utilities include them. This will need to be fixed later. 527 If "mount -t oldnfs ..." is attempted, it will fail. 528 If the "-o" option on mountd(8), nfsd(8) or nfsstat(1) is used, 529 the utilities will report errors. 530 53120141121: 532 The handling of LOCAL_LIB_DIRS has been altered to skip addition of 533 directories to top level SUBDIR variable when their parent 534 directory is included in LOCAL_DIRS. Users with build systems with 535 such hierarchies and without SUBDIR entries in the parent 536 directory Makefiles should add them or add the directories to 537 LOCAL_DIRS. 538 53920141109: 540 faith(4) and faithd(8) have been removed from the base system. Faith 541 has been obsolete for a very long time. 542 54320141104: 544 vt(4), the new console driver, is enabled by default. It brings 545 support for Unicode and double-width characters, as well as 546 support for UEFI and integration with the KMS kernel video 547 drivers. 548 549 You may need to update your console settings in /etc/rc.conf, 550 most probably the keymap. During boot, /etc/rc.d/syscons will 551 indicate what you need to do. 552 553 vt(4) still has issues and lacks some features compared to 554 syscons(4). See the wiki for up-to-date information: 555 https://wiki.freebsd.org/Newcons 556 557 If you want to keep using syscons(4), you can do so by adding 558 the following line to /boot/loader.conf: 559 kern.vty=sc 560 56120141102: 562 pjdfstest has been integrated into kyua as an opt-in test suite. 563 Please see share/doc/pjdfstest/README for more details on how to 564 execute it. 565 56620141009: 567 gperf has been removed from the base system for architectures 568 that use clang. Ports that require gperf will obtain it from the 569 devel/gperf port. 570 57120140923: 572 pjdfstest has been moved from tools/regression/pjdfstest to 573 contrib/pjdfstest . 574 57520140922: 576 At svn r271982, The default linux compat kernel ABI has been adjusted 577 to 2.6.18 in support of the linux-c6 compat ports infrastructure 578 update. If you wish to continue using the linux-f10 compat ports, 579 add compat.linux.osrelease=2.6.16 to your local sysctl.conf. Users are 580 encouraged to update their linux-compat packages to linux-c6 during 581 their next update cycle. 582 58320140729: 584 The ofwfb driver, used to provide a graphics console on PowerPC when 585 using vt(4), no longer allows mmap() of all physical memory. This 586 will prevent Xorg on PowerPC with some ATI graphics cards from 587 initializing properly unless x11-servers/xorg-server is updated to 588 1.12.4_8 or newer. 589 59020140723: 591 The xdev targets have been converted to using TARGET and 592 TARGET_ARCH instead of XDEV and XDEV_ARCH. 593 59420140719: 595 The default unbound configuration has been modified to address 596 issues with reverse lookups on networks that use private 597 address ranges. If you use the local_unbound service, run 598 "service local_unbound setup" as root to regenerate your 599 configuration, then "service local_unbound reload" to load the 600 new configuration. 601 60220140709: 603 The GNU texinfo and GNU info pages are not built and installed 604 anymore, WITH_INFO knob has been added to allow to built and install 605 them again. 606 UPDATE: see 20150102 entry on texinfo's removal 607 60820140708: 609 The GNU readline library is now an INTERNALLIB - that is, it is 610 statically linked into consumers (GDB and variants) in the base 611 system, and the shared library is no longer installed. The 612 devel/readline port is available for third party software that 613 requires readline. 614 61520140702: 616 The Itanium architecture (ia64) has been removed from the list of 617 known architectures. This is the first step in the removal of the 618 architecture. 619 62020140701: 621 Commit r268115 has added NFSv4.1 server support, merged from 622 projects/nfsv4.1-server. Since this includes changes to the 623 internal interfaces between the NFS related modules, a full 624 build of the kernel and modules will be necessary. 625 __FreeBSD_version has been bumped. 626 62720140629: 628 The WITHOUT_VT_SUPPORT kernel config knob has been renamed 629 WITHOUT_VT. (The other _SUPPORT knobs have a consistent meaning 630 which differs from the behaviour controlled by this knob.) 631 63220140619: 633 Maximal length of the serial number in CTL was increased from 16 to 634 64 chars, that breaks ABI. All CTL-related tools, such as ctladm 635 and ctld, need to be rebuilt to work with a new kernel. 636 63720140606: 638 The libatf-c and libatf-c++ major versions were downgraded to 0 and 639 1 respectively to match the upstream numbers. They were out of 640 sync because, when they were originally added to FreeBSD, the 641 upstream versions were not respected. These libraries are private 642 and not yet built by default, so renumbering them should be a 643 non-issue. However, unclean source trees will yield broken test 644 programs once the operator executes "make delete-old-libs" after a 645 "make installworld". 646 647 Additionally, the atf-sh binary was made private by moving it into 648 /usr/libexec/. Already-built shell test programs will keep the 649 path to the old binary so they will break after "make delete-old" 650 is run. 651 652 If you are using WITH_TESTS=yes (not the default), wipe the object 653 tree and rebuild from scratch to prevent spurious test failures. 654 This is only needed once: the misnumbered libraries and misplaced 655 binaries have been added to OptionalObsoleteFiles.inc so they will 656 be removed during a clean upgrade. 657 65820140512: 659 Clang and llvm have been upgraded to 3.4.1 release. 660 66120140508: 662 We bogusly installed src.opts.mk in /usr/share/mk. This file should 663 be removed to avoid issues in the future (and has been added to 664 ObsoleteFiles.inc). 665 66620140505: 667 /etc/src.conf now affects only builds of the FreeBSD src tree. In the 668 past, it affected all builds that used the bsd.*.mk files. The old 669 behavior was a bug, but people may have relied upon it. To get this 670 behavior back, you can .include /etc/src.conf from /etc/make.conf 671 (which is still global and isn't changed). This also changes the 672 behavior of incremental builds inside the tree of individual 673 directories. Set MAKESYSPATH to ".../share/mk" to do that. 674 Although this has survived make universe and some upgrade scenarios, 675 other upgrade scenarios may have broken. At least one form of 676 temporary breakage was fixed with MAKESYSPATH settings for buildworld 677 as well... In cases where MAKESYSPATH isn't working with this 678 setting, you'll need to set it to the full path to your tree. 679 680 One side effect of all this cleaning up is that bsd.compiler.mk 681 is no longer implicitly included by bsd.own.mk. If you wish to 682 use COMPILER_TYPE, you must now explicitly include bsd.compiler.mk 683 as well. 684 68520140430: 686 The lindev device has been removed since /dev/full has been made a 687 standard device. __FreeBSD_version has been bumped. 688 68920140424: 690 The knob WITHOUT_VI was added to the base system, which controls 691 building ex(1), vi(1), etc. Older releases of FreeBSD required ex(1) 692 in order to reorder files share/termcap and didn't build ex(1) as a 693 build tool, so building/installing with WITH_VI is highly advised for 694 build hosts for older releases. 695 696 This issue has been fixed in stable/9 and stable/10 in r277022 and 697 r276991, respectively. 698 69920140418: 700 The YES_HESIOD knob has been removed. It has been obsolete for 701 a decade. Please move to using WITH_HESIOD instead or your builds 702 will silently lack HESIOD. 703 70420140405: 705 The uart(4) driver has been changed with respect to its handling 706 of the low-level console. Previously the uart(4) driver prevented 707 any process from changing the baudrate or the CLOCAL and HUPCL 708 control flags. By removing the restrictions, operators can make 709 changes to the serial console port without having to reboot. 710 However, when getty(8) is started on the serial device that is 711 associated with the low-level console, a misconfigured terminal 712 line in /etc/ttys will now have a real impact. 713 Before upgrading the kernel, make sure that /etc/ttys has the 714 serial console device configured as 3wire without baudrate to 715 preserve the previous behaviour. E.g: 716 ttyu0 "/usr/libexec/getty 3wire" vt100 on secure 717 71820140306: 719 Support for libwrap (TCP wrappers) in rpcbind was disabled by default 720 to improve performance. To re-enable it, if needed, run rpcbind 721 with command line option -W. 722 72320140226: 724 Switched back to the GPL dtc compiler due to updates in the upstream 725 dts files not being supported by the BSDL dtc compiler. You will need 726 to rebuild your kernel toolchain to pick up the new compiler. Core dumps 727 may result while building dtb files during a kernel build if you fail 728 to do so. Set WITHOUT_GPL_DTC if you require the BSDL compiler. 729 73020140216: 731 Clang and llvm have been upgraded to 3.4 release. 732 73320140216: 734 The nve(4) driver has been removed. Please use the nfe(4) driver 735 for NVIDIA nForce MCP Ethernet adapters instead. 736 73720140212: 738 An ABI incompatibility crept into the libc++ 3.4 import in r261283. 739 This could cause certain C++ applications using shared libraries built 740 against the previous version of libc++ to crash. The incompatibility 741 has now been fixed, but any C++ applications or shared libraries built 742 between r261283 and r261801 should be recompiled. 743 74420140204: 745 OpenSSH will now ignore errors caused by kernel lacking of Capsicum 746 capability mode support. Please note that enabling the feature in 747 kernel is still highly recommended. 748 74920140131: 750 OpenSSH is now built with sandbox support, and will use sandbox as 751 the default privilege separation method. This requires Capsicum 752 capability mode support in kernel. 753 75420140128: 755 The libelf and libdwarf libraries have been updated to newer 756 versions from upstream. Shared library version numbers for 757 these two libraries were bumped. Any ports or binaries 758 requiring these two libraries should be recompiled. 759 __FreeBSD_version is bumped to 1100006. 760 76120140110: 762 If a Makefile in a tests/ directory was auto-generating a Kyuafile 763 instead of providing an explicit one, this would prevent such 764 Makefile from providing its own Kyuafile in the future during 765 NO_CLEAN builds. This has been fixed in the Makefiles but manual 766 intervention is needed to clean an objdir if you use NO_CLEAN: 767 # find /usr/obj -name Kyuafile | xargs rm -f 768 76920131213: 770 The behavior of gss_pseudo_random() for the krb5 mechanism 771 has changed, for applications requesting a longer random string 772 than produced by the underlying enctype's pseudo-random() function. 773 In particular, the random string produced from a session key of 774 enctype aes256-cts-hmac-sha1-96 or aes256-cts-hmac-sha1-96 will 775 be different at the 17th octet and later, after this change. 776 The counter used in the PRF+ construction is now encoded as a 777 big-endian integer in accordance with RFC 4402. 778 __FreeBSD_version is bumped to 1100004. 779 78020131108: 781 The WITHOUT_ATF build knob has been removed and its functionality 782 has been subsumed into the more generic WITHOUT_TESTS. If you were 783 using the former to disable the build of the ATF libraries, you 784 should change your settings to use the latter. 785 78620131025: 787 The default version of mtree is nmtree which is obtained from 788 NetBSD. The output is generally the same, but may vary 789 slightly. If you found you need identical output adding 790 "-F freebsd9" to the command line should do the trick. For the 791 time being, the old mtree is available as fmtree. 792 79320131014: 794 libbsdyml has been renamed to libyaml and moved to /usr/lib/private. 795 This will break ports-mgmt/pkg. Rebuild the port, or upgrade to pkg 796 1.1.4_8 and verify bsdyml not linked in, before running "make 797 delete-old-libs": 798 # make -C /usr/ports/ports-mgmt/pkg build deinstall install clean 799 or 800 # pkg install pkg; ldd /usr/local/sbin/pkg | grep bsdyml 801 80220131010: 803 The stable/10 branch has been created in subversion from head 804 revision r256279. 805 80620131010: 807 The rc.d/jail script has been updated to support jail(8) 808 configuration file. The "jail_<jname>_*" rc.conf(5) variables 809 for per-jail configuration are automatically converted to 810 /var/run/jail.<jname>.conf before the jail(8) utility is invoked. 811 This is transparently backward compatible. See below about some 812 incompatibilities and rc.conf(5) manual page for more details. 813 814 These variables are now deprecated in favor of jail(8) configuration 815 file. One can use "rc.d/jail config <jname>" command to generate 816 a jail(8) configuration file in /var/run/jail.<jname>.conf without 817 running the jail(8) utility. The default pathname of the 818 configuration file is /etc/jail.conf and can be specified by 819 using $jail_conf or $jail_<jname>_conf variables. 820 821 Please note that jail_devfs_ruleset accepts an integer at 822 this moment. Please consider to rewrite the ruleset name 823 with an integer. 824 82520130930: 826 BIND has been removed from the base system. If all you need 827 is a local resolver, simply enable and start the local_unbound 828 service instead. Otherwise, several versions of BIND are 829 available in the ports tree. The dns/bind99 port is one example. 830 831 With this change, nslookup(1) and dig(1) are no longer in the base 832 system. Users should instead use host(1) and drill(1) which are 833 in the base system. Alternatively, nslookup and dig can 834 be obtained by installing the dns/bind-tools port. 835 83620130916: 837 With the addition of unbound(8), a new unbound user is now 838 required during installworld. "mergemaster -p" can be used to 839 add the user prior to installworld, as documented in the handbook. 840 84120130911: 842 OpenSSH is now built with DNSSEC support, and will by default 843 silently trust signed SSHFP records. This can be controlled with 844 the VerifyHostKeyDNS client configuration setting. DNSSEC support 845 can be disabled entirely with the WITHOUT_LDNS option in src.conf. 846 84720130906: 848 The GNU Compiler Collection and C++ standard library (libstdc++) 849 are no longer built by default on platforms where clang is the system 850 compiler. You can enable them with the WITH_GCC and WITH_GNUCXX 851 options in src.conf. 852 85320130905: 854 The PROCDESC kernel option is now part of the GENERIC kernel 855 configuration and is required for the rwhod(8) to work. 856 If you are using custom kernel configuration, you should include 857 'options PROCDESC'. 858 85920130905: 860 The API and ABI related to the Capsicum framework was modified 861 in backward incompatible way. The userland libraries and programs 862 have to be recompiled to work with the new kernel. This includes the 863 following libraries and programs, but the whole buildworld is 864 advised: libc, libprocstat, dhclient, tcpdump, hastd, hastctl, 865 kdump, procstat, rwho, rwhod, uniq. 866 86720130903: 868 AES-NI intrinsic support has been added to gcc. The AES-NI module 869 has been updated to use this support. A new gcc is required to build 870 the aesni module on both i386 and amd64. 871 87220130821: 873 The PADLOCK_RNG and RDRAND_RNG kernel options are now devices. 874 Thus "device padlock_rng" and "device rdrand_rng" should be 875 used instead of "options PADLOCK_RNG" & "options RDRAND_RNG". 876 87720130813: 878 WITH_ICONV has been split into two feature sets. WITH_ICONV now 879 enables just the iconv* functionality and is now on by default. 880 WITH_LIBICONV_COMPAT enables the libiconv api and link time 881 compatability. Set WITHOUT_ICONV to build the old way. 882 If you have been using WITH_ICONV before, you will very likely 883 need to turn on WITH_LIBICONV_COMPAT. 884 88520130806: 886 INVARIANTS option now enables DEBUG for code with OpenSolaris and 887 Illumos origin, including ZFS. If you have INVARIANTS in your 888 kernel configuration, then there is no need to set DEBUG or ZFS_DEBUG 889 explicitly. 890 DEBUG used to enable witness(9) tracking of OpenSolaris (mostly ZFS) 891 locks if WITNESS option was set. Because that generated a lot of 892 witness(9) reports and all of them were believed to be false 893 positives, this is no longer done. New option OPENSOLARIS_WITNESS 894 can be used to achieve the previous behavior. 895 89620130806: 897 Timer values in IPv6 data structures now use time_uptime instead 898 of time_second. Although this is not a user-visible functional 899 change, userland utilities which directly use them---ndp(8), 900 rtadvd(8), and rtsold(8) in the base system---need to be updated 901 to r253970 or later. 902 90320130802: 904 find -delete can now delete the pathnames given as arguments, 905 instead of only files found below them or if the pathname did 906 not contain any slashes. Formerly, the following error message 907 would result: 908 909 find: -delete: <path>: relative path potentially not safe 910 911 Deleting the pathnames given as arguments can be prevented 912 without error messages using -mindepth 1 or by changing 913 directory and passing "." as argument to find. This works in the 914 old as well as the new version of find. 915 91620130726: 917 Behavior of devfs rules path matching has been changed. 918 Pattern is now always matched against fully qualified devfs 919 path and slash characters must be explicitly matched by 920 slashes in pattern (FNM_PATHNAME). Rulesets involving devfs 921 subdirectories must be reviewed. 922 92320130716: 924 The default ARM ABI has changed to the ARM EABI. The old ABI is 925 incompatible with the ARM EABI and all programs and modules will 926 need to be rebuilt to work with a new kernel. 927 928 To keep using the old ABI ensure the WITHOUT_ARM_EABI knob is set. 929 930 NOTE: Support for the old ABI will be removed in the future and 931 users are advised to upgrade. 932 93320130709: 934 pkg_install has been disconnected from the build if you really need it 935 you should add WITH_PKGTOOLS in your src.conf(5). 936 93720130709: 938 Most of network statistics structures were changed to be able 939 keep 64-bits counters. Thus all tools, that work with networking 940 statistics, must be rebuilt (netstat(1), bsnmpd(1), etc.) 941 94220130618: 943 Fix a bug that allowed a tracing process (e.g. gdb) to write 944 to a memory-mapped file in the traced process's address space 945 even if neither the traced process nor the tracing process had 946 write access to that file. 947 94820130615: 949 CVS has been removed from the base system. An exact copy 950 of the code is available from the devel/cvs port. 951 95220130613: 953 Some people report the following error after the switch to bmake: 954 955 make: illegal option -- J 956 usage: make [-BPSXeiknpqrstv] [-C directory] [-D variable] 957 ... 958 *** [buildworld] Error code 2 959 960 this likely due to an old instance of make in 961 ${MAKEPATH} (${MAKEOBJDIRPREFIX}${.CURDIR}/make.${MACHINE}) 962 which src/Makefile will use that blindly, if it exists, so if 963 you see the above error: 964 965 rm -rf `make -V MAKEPATH` 966 967 should resolve it. 968 96920130516: 970 Use bmake by default. 971 Whereas before one could choose to build with bmake via 972 -DWITH_BMAKE one must now use -DWITHOUT_BMAKE to use the old 973 make. The goal is to remove these knobs for 10-RELEASE. 974 975 It is worth noting that bmake (like gmake) treats the command 976 line as the unit of failure, rather than statements within the 977 command line. Thus '(cd some/where && dosomething)' is safer 978 than 'cd some/where; dosomething'. The '()' allows consistent 979 behavior in parallel build. 980 98120130429: 982 Fix a bug that allows NFS clients to issue READDIR on files. 983 98420130426: 985 The WITHOUT_IDEA option has been removed because 986 the IDEA patent expired. 987 98820130426: 989 The sysctl which controls TRIM support under ZFS has been renamed 990 from vfs.zfs.trim_disable -> vfs.zfs.trim.enabled and has been 991 enabled by default. 992 99320130425: 994 The mergemaster command now uses the default MAKEOBJDIRPREFIX 995 rather than creating it's own in the temporary directory in 996 order allow access to bootstrapped versions of tools such as 997 install and mtree. When upgrading from version of FreeBSD where 998 the install command does not support -l, you will need to 999 install a new mergemaster command if mergemaster -p is required. 1000 This can be accomplished with the command (cd src/usr.sbin/mergemaster 1001 && make install). 1002 100320130404: 1004 Legacy ATA stack, disabled and replaced by new CAM-based one since 1005 FreeBSD 9.0, completely removed from the sources. Kernel modules 1006 atadisk and atapi*, user-level tools atacontrol and burncd are 1007 removed. Kernel option `options ATA_CAM` is now permanently enabled 1008 and removed. 1009 101020130319: 1011 SOCK_CLOEXEC and SOCK_NONBLOCK flags have been added to socket(2) 1012 and socketpair(2). Software, in particular Kerberos, may 1013 automatically detect and use these during building. The resulting 1014 binaries will not work on older kernels. 1015 101620130308: 1017 CTL_DISABLE has also been added to the sparc64 GENERIC (for further 1018 information, see the respective 20130304 entry). 1019 102020130304: 1021 Recent commits to callout(9) changed the size of struct callout, 1022 so the KBI is probably heavily disturbed. Also, some functions 1023 in callout(9)/sleep(9)/sleepqueue(9)/condvar(9) KPIs were replaced 1024 by macros. Every kernel module using it won't load, so rebuild 1025 is requested. 1026 1027 The ctl device has been re-enabled in GENERIC for i386 and amd64, 1028 but does not initialize by default (because of the new CTL_DISABLE 1029 option) to save memory. To re-enable it, remove the CTL_DISABLE 1030 option from the kernel config file or set kern.cam.ctl.disable=0 1031 in /boot/loader.conf. 1032 103320130301: 1034 The ctl device has been disabled in GENERIC for i386 and amd64. 1035 This was done due to the extra memory being allocated at system 1036 initialisation time by the ctl driver which was only used if 1037 a CAM target device was created. This makes a FreeBSD system 1038 unusable on 128MB or less of RAM. 1039 104020130208: 1041 A new compression method (lz4) has been merged to -HEAD. Please 1042 refer to zpool-features(7) for more information. 1043 1044 Please refer to the "ZFS notes" section of this file for information 1045 on upgrading boot ZFS pools. 1046 104720130129: 1048 A BSD-licensed patch(1) variant has been added and is installed 1049 as bsdpatch, being the GNU version the default patch. 1050 To inverse the logic and use the BSD-licensed one as default, 1051 while having the GNU version installed as gnupatch, rebuild 1052 and install world with the WITH_BSD_PATCH knob set. 1053 105420130121: 1055 Due to the use of the new -l option to install(1) during build 1056 and install, you must take care not to directly set the INSTALL 1057 make variable in your /etc/make.conf, /etc/src.conf, or on the 1058 command line. If you wish to use the -C flag for all installs 1059 you may be able to add INSTALL+=-C to /etc/make.conf or 1060 /etc/src.conf. 1061 106220130118: 1063 The install(1) option -M has changed meaning and now takes an 1064 argument that is a file or path to append logs to. In the 1065 unlikely event that -M was the last option on the command line 1066 and the command line contained at least two files and a target 1067 directory the first file will have logs appended to it. The -M 1068 option served little practical purpose in the last decade so its 1069 use is expected to be extremely rare. 1070 107120121223: 1072 After switching to Clang as the default compiler some users of ZFS 1073 on i386 systems started to experience stack overflow kernel panics. 1074 Please consider using 'options KSTACK_PAGES=4' in such configurations. 1075 107620121222: 1077 GEOM_LABEL now mangles label names read from file system metadata. 1078 Mangling affect labels containing spaces, non-printable characters, 1079 '%' or '"'. Device names in /etc/fstab and other places may need to 1080 be updated. 1081 108220121217: 1083 By default, only the 10 most recent kernel dumps will be saved. To 1084 restore the previous behaviour (no limit on the number of kernel dumps 1085 stored in the dump directory) add the following line to /etc/rc.conf: 1086 1087 savecore_flags="" 1088 108920121201: 1090 With the addition of auditdistd(8), a new auditdistd user is now 1091 required during installworld. "mergemaster -p" can be used to 1092 add the user prior to installworld, as documented in the handbook. 1093 109420121117: 1095 The sin6_scope_id member variable in struct sockaddr_in6 is now 1096 filled by the kernel before passing the structure to the userland via 1097 sysctl or routing socket. This means the KAME-specific embedded scope 1098 id in sin6_addr.s6_addr[2] is always cleared in userland application. 1099 This behavior can be controlled by net.inet6.ip6.deembed_scopeid. 1100 __FreeBSD_version is bumped to 1000025. 1101 110220121105: 1103 On i386 and amd64 systems WITH_CLANG_IS_CC is now the default. 1104 This means that the world and kernel will be compiled with clang 1105 and that clang will be installed as /usr/bin/cc, /usr/bin/c++, 1106 and /usr/bin/cpp. To disable this behavior and revert to building 1107 with gcc, compile with WITHOUT_CLANG_IS_CC. Really old versions 1108 of current may need to bootstrap WITHOUT_CLANG first if the clang 1109 build fails (its compatibility window doesn't extend to the 9 stable 1110 branch point). 1111 111220121102: 1113 The IPFIREWALL_FORWARD kernel option has been removed. Its 1114 functionality now turned on by default. 1115 111620121023: 1117 The ZERO_COPY_SOCKET kernel option has been removed and 1118 split into SOCKET_SEND_COW and SOCKET_RECV_PFLIP. 1119 NB: SOCKET_SEND_COW uses the VM page based copy-on-write 1120 mechanism which is not safe and may result in kernel crashes. 1121 NB: The SOCKET_RECV_PFLIP mechanism is useless as no current 1122 driver supports disposeable external page sized mbuf storage. 1123 Proper replacements for both zero-copy mechanisms are under 1124 consideration and will eventually lead to complete removal 1125 of the two kernel options. 1126 112720121023: 1128 The IPv4 network stack has been converted to network byte 1129 order. The following modules need to be recompiled together 1130 with kernel: carp(4), divert(4), gif(4), siftr(4), gre(4), 1131 pf(4), ipfw(4), ng_ipfw(4), stf(4). 1132 113320121022: 1134 Support for non-MPSAFE filesystems was removed from VFS. The 1135 VFS_VERSION was bumped, all filesystem modules shall be 1136 recompiled. 1137 113820121018: 1139 All the non-MPSAFE filesystems have been disconnected from 1140 the build. The full list includes: codafs, hpfs, ntfs, nwfs, 1141 portalfs, smbfs, xfs. 1142 114320121016: 1144 The interface cloning API and ABI has changed. The following 1145 modules need to be recompiled together with kernel: 1146 ipfw(4), pfsync(4), pflog(4), usb(4), wlan(4), stf(4), 1147 vlan(4), disc(4), edsc(4), if_bridge(4), gif(4), tap(4), 1148 faith(4), epair(4), enc(4), tun(4), if_lagg(4), gre(4). 1149 115020121015: 1151 The sdhci driver was split in two parts: sdhci (generic SD Host 1152 Controller logic) and sdhci_pci (actual hardware driver). 1153 No kernel config modifications are required, but if you 1154 load sdhc as a module you must switch to sdhci_pci instead. 1155 115620121014: 1157 Import the FUSE kernel and userland support into base system. 1158 115920121013: 1160 The GNU sort(1) program has been removed since the BSD-licensed 1161 sort(1) has been the default for quite some time and no serious 1162 problems have been reported. The corresponding WITH_GNU_SORT 1163 knob has also gone. 1164 116520121006: 1166 The pfil(9) API/ABI for AF_INET family has been changed. Packet 1167 filtering modules: pf(4), ipfw(4), ipfilter(4) need to be recompiled 1168 with new kernel. 1169 117020121001: 1171 The net80211(4) ABI has been changed to allow for improved driver 1172 PS-POLL and power-save support. All wireless drivers need to be 1173 recompiled to work with the new kernel. 1174 117520120913: 1176 The random(4) support for the VIA hardware random number 1177 generator (`PADLOCK') is no longer enabled unconditionally. 1178 Add the padlock_rng device in the custom kernel config if 1179 needed. The GENERIC kernels on i386 and amd64 do include the 1180 device, so the change only affects the custom kernel 1181 configurations. 1182 118320120908: 1184 The pf(4) packet filter ABI has been changed. pfctl(8) and 1185 snmp_pf module need to be recompiled to work with new kernel. 1186 118720120828: 1188 A new ZFS feature flag "com.delphix:empty_bpobj" has been merged 1189 to -HEAD. Pools that have empty_bpobj in active state can not be 1190 imported read-write with ZFS implementations that do not support 1191 this feature. For more information read the zpool-features(5) 1192 manual page. 1193 119420120727: 1195 The sparc64 ZFS loader has been changed to no longer try to auto- 1196 detect ZFS providers based on diskN aliases but now requires these 1197 to be explicitly listed in the OFW boot-device environment variable. 1198 119920120712: 1200 The OpenSSL has been upgraded to 1.0.1c. Any binaries requiring 1201 libcrypto.so.6 or libssl.so.6 must be recompiled. Also, there are 1202 configuration changes. Make sure to merge /etc/ssl/openssl.cnf. 1203 120420120712: 1205 The following sysctls and tunables have been renamed for consistency 1206 with other variables: 1207 kern.cam.da.da_send_ordered -> kern.cam.da.send_ordered 1208 kern.cam.ada.ada_send_ordered -> kern.cam.ada.send_ordered 1209 121020120628: 1211 The sort utility has been replaced with BSD sort. For now, GNU sort 1212 is also available as "gnusort" or the default can be set back to 1213 GNU sort by setting WITH_GNU_SORT. In this case, BSD sort will be 1214 installed as "bsdsort". 1215 121620120611: 1217 A new version of ZFS (pool version 5000) has been merged to -HEAD. 1218 Starting with this version the old system of ZFS pool versioning 1219 is superseded by "feature flags". This concept enables forward 1220 compatibility against certain future changes in functionality of ZFS 1221 pools. The first read-only compatible "feature flag" for ZFS pools 1222 is named "com.delphix:async_destroy". For more information 1223 read the new zpool-features(5) manual page. 1224 Please refer to the "ZFS notes" section of this file for information 1225 on upgrading boot ZFS pools. 1226 122720120417: 1228 The malloc(3) implementation embedded in libc now uses sources imported 1229 as contrib/jemalloc. The most disruptive API change is to 1230 /etc/malloc.conf. If your system has an old-style /etc/malloc.conf, 1231 delete it prior to installworld, and optionally re-create it using the 1232 new format after rebooting. See malloc.conf(5) for details 1233 (specifically the TUNING section and the "opt.*" entries in the MALLCTL 1234 NAMESPACE section). 1235 123620120328: 1237 Big-endian MIPS TARGET_ARCH values no longer end in "eb". mips64eb 1238 is now spelled mips64. mipsn32eb is now spelled mipsn32. mipseb is 1239 now spelled mips. This is to aid compatibility with third-party 1240 software that expects this naming scheme in uname(3). Little-endian 1241 settings are unchanged. If you are updating a big-endian mips64 machine 1242 from before this change, you may need to set MACHINE_ARCH=mips64 in 1243 your environment before the new build system will recognize your machine. 1244 124520120306: 1246 Disable by default the option VFS_ALLOW_NONMPSAFE for all supported 1247 platforms. 1248 124920120229: 1250 Now unix domain sockets behave "as expected" on nullfs(5). Previously 1251 nullfs(5) did not pass through all behaviours to the underlying layer, 1252 as a result if we bound to a socket on the lower layer we could connect 1253 only to the lower path; if we bound to the upper layer we could connect 1254 only to the upper path. The new behavior is one can connect to both the 1255 lower and the upper paths regardless what layer path one binds to. 1256 125720120211: 1258 The getifaddrs upgrade path broken with 20111215 has been restored. 1259 If you have upgraded in between 20111215 and 20120209 you need to 1260 recompile libc again with your kernel. You still need to recompile 1261 world to be able to configure CARP but this restriction already 1262 comes from 20111215. 1263 126420120114: 1265 The set_rcvar() function has been removed from /etc/rc.subr. All 1266 base and ports rc.d scripts have been updated, so if you have a 1267 port installed with a script in /usr/local/etc/rc.d you can either 1268 hand-edit the rcvar= line, or reinstall the port. 1269 1270 An easy way to handle the mass-update of /etc/rc.d: 1271 rm /etc/rc.d/* && mergemaster -i 1272 127320120109: 1274 panic(9) now stops other CPUs in the SMP systems, disables interrupts 1275 on the current CPU and prevents other threads from running. 1276 This behavior can be reverted using the kern.stop_scheduler_on_panic 1277 tunable/sysctl. 1278 The new behavior can be incompatible with kern.sync_on_panic. 1279 128020111215: 1281 The carp(4) facility has been changed significantly. Configuration 1282 of the CARP protocol via ifconfig(8) has changed, as well as format 1283 of CARP events submitted to devd(8) has changed. See manual pages 1284 for more information. The arpbalance feature of carp(4) is currently 1285 not supported anymore. 1286 1287 Size of struct in_aliasreq, struct in6_aliasreq has changed. User 1288 utilities using SIOCAIFADDR, SIOCAIFADDR_IN6, e.g. ifconfig(8), 1289 need to be recompiled. 1290 129120111122: 1292 The acpi_wmi(4) status device /dev/wmistat has been renamed to 1293 /dev/wmistat0. 1294 129520111108: 1296 The option VFS_ALLOW_NONMPSAFE option has been added in order to 1297 explicitely support non-MPSAFE filesystems. 1298 It is on by default for all supported platform at this present 1299 time. 1300 130120111101: 1302 The broken amd(4) driver has been replaced with esp(4) in the amd64, 1303 i386 and pc98 GENERIC kernel configuration files. 1304 130520110930: 1306 sysinstall has been removed 1307 130820110923: 1309 The stable/9 branch created in subversion. This corresponds to the 1310 RELENG_9 branch in CVS. 1311 1312COMMON ITEMS: 1313 1314 General Notes 1315 ------------- 1316 Avoid using make -j when upgrading. While generally safe, there are 1317 sometimes problems using -j to upgrade. If your upgrade fails with 1318 -j, please try again without -j. From time to time in the past there 1319 have been problems using -j with buildworld and/or installworld. This 1320 is especially true when upgrading between "distant" versions (eg one 1321 that cross a major release boundary or several minor releases, or when 1322 several months have passed on the -current branch). 1323 1324 Sometimes, obscure build problems are the result of environment 1325 poisoning. This can happen because the make utility reads its 1326 environment when searching for values for global variables. To run 1327 your build attempts in an "environmental clean room", prefix all make 1328 commands with 'env -i '. See the env(1) manual page for more details. 1329 1330 When upgrading from one major version to another it is generally best 1331 to upgrade to the latest code in the currently installed branch first, 1332 then do an upgrade to the new branch. This is the best-tested upgrade 1333 path, and has the highest probability of being successful. Please try 1334 this approach before reporting problems with a major version upgrade. 1335 1336 When upgrading a live system, having a root shell around before 1337 installing anything can help undo problems. Not having a root shell 1338 around can lead to problems if pam has changed too much from your 1339 starting point to allow continued authentication after the upgrade. 1340 1341 This file should be read as a log of events. When a later event changes 1342 information of a prior event, the prior event should not be deleted. 1343 Instead, a pointer to the entry with the new information should be 1344 placed in the old entry. Readers of this file should also sanity check 1345 older entries before relying on them blindly. Authors of new entries 1346 should write them with this in mind. 1347 1348 ZFS notes 1349 --------- 1350 When upgrading the boot ZFS pool to a new version, always follow 1351 these two steps: 1352 1353 1.) recompile and reinstall the ZFS boot loader and boot block 1354 (this is part of "make buildworld" and "make installworld") 1355 1356 2.) update the ZFS boot block on your boot drive 1357 1358 The following example updates the ZFS boot block on the first 1359 partition (freebsd-boot) of a GPT partitioned drive ada0: 1360 "gpart bootcode -p /boot/gptzfsboot -i 1 ada0" 1361 1362 Non-boot pools do not need these updates. 1363 1364 To build a kernel 1365 ----------------- 1366 If you are updating from a prior version of FreeBSD (even one just 1367 a few days old), you should follow this procedure. It is the most 1368 failsafe as it uses a /usr/obj tree with a fresh mini-buildworld, 1369 1370 make kernel-toolchain 1371 make -DALWAYS_CHECK_MAKE buildkernel KERNCONF=YOUR_KERNEL_HERE 1372 make -DALWAYS_CHECK_MAKE installkernel KERNCONF=YOUR_KERNEL_HERE 1373 1374 To test a kernel once 1375 --------------------- 1376 If you just want to boot a kernel once (because you are not sure 1377 if it works, or if you want to boot a known bad kernel to provide 1378 debugging information) run 1379 make installkernel KERNCONF=YOUR_KERNEL_HERE KODIR=/boot/testkernel 1380 nextboot -k testkernel 1381 1382 To just build a kernel when you know that it won't mess you up 1383 -------------------------------------------------------------- 1384 This assumes you are already running a CURRENT system. Replace 1385 ${arch} with the architecture of your machine (e.g. "i386", 1386 "arm", "amd64", "ia64", "pc98", "sparc64", "powerpc", "mips", etc). 1387 1388 cd src/sys/${arch}/conf 1389 config KERNEL_NAME_HERE 1390 cd ../compile/KERNEL_NAME_HERE 1391 make depend 1392 make 1393 make install 1394 1395 If this fails, go to the "To build a kernel" section. 1396 1397 To rebuild everything and install it on the current system. 1398 ----------------------------------------------------------- 1399 # Note: sometimes if you are running current you gotta do more than 1400 # is listed here if you are upgrading from a really old current. 1401 1402 <make sure you have good level 0 dumps> 1403 make buildworld 1404 make kernel KERNCONF=YOUR_KERNEL_HERE 1405 [1] 1406 <reboot in single user> [3] 1407 mergemaster -Fp [5] 1408 make installworld 1409 mergemaster -Fi [4] 1410 make delete-old [6] 1411 <reboot> 1412 1413 To cross-install current onto a separate partition 1414 -------------------------------------------------- 1415 # In this approach we use a separate partition to hold 1416 # current's root, 'usr', and 'var' directories. A partition 1417 # holding "/", "/usr" and "/var" should be about 2GB in 1418 # size. 1419 1420 <make sure you have good level 0 dumps> 1421 <boot into -stable> 1422 make buildworld 1423 make buildkernel KERNCONF=YOUR_KERNEL_HERE 1424 <maybe newfs current's root partition> 1425 <mount current's root partition on directory ${CURRENT_ROOT}> 1426 make installworld DESTDIR=${CURRENT_ROOT} -DDB_FROM_SRC 1427 make distribution DESTDIR=${CURRENT_ROOT} # if newfs'd 1428 make installkernel KERNCONF=YOUR_KERNEL_HERE DESTDIR=${CURRENT_ROOT} 1429 cp /etc/fstab ${CURRENT_ROOT}/etc/fstab # if newfs'd 1430 <edit ${CURRENT_ROOT}/etc/fstab to mount "/" from the correct partition> 1431 <reboot into current> 1432 <do a "native" rebuild/install as described in the previous section> 1433 <maybe install compatibility libraries from ports/misc/compat*> 1434 <reboot> 1435 1436 1437 To upgrade in-place from stable to current 1438 ---------------------------------------------- 1439 <make sure you have good level 0 dumps> 1440 make buildworld [9] 1441 make kernel KERNCONF=YOUR_KERNEL_HERE [8] 1442 [1] 1443 <reboot in single user> [3] 1444 mergemaster -Fp [5] 1445 make installworld 1446 mergemaster -Fi [4] 1447 make delete-old [6] 1448 <reboot> 1449 1450 Make sure that you've read the UPDATING file to understand the 1451 tweaks to various things you need. At this point in the life 1452 cycle of current, things change often and you are on your own 1453 to cope. The defaults can also change, so please read ALL of 1454 the UPDATING entries. 1455 1456 Also, if you are tracking -current, you must be subscribed to 1457 freebsd-current@freebsd.org. Make sure that before you update 1458 your sources that you have read and understood all the recent 1459 messages there. If in doubt, please track -stable which has 1460 much fewer pitfalls. 1461 1462 [1] If you have third party modules, such as vmware, you 1463 should disable them at this point so they don't crash your 1464 system on reboot. 1465 1466 [3] From the bootblocks, boot -s, and then do 1467 fsck -p 1468 mount -u / 1469 mount -a 1470 cd src 1471 adjkerntz -i # if CMOS is wall time 1472 Also, when doing a major release upgrade, it is required that 1473 you boot into single user mode to do the installworld. 1474 1475 [4] Note: This step is non-optional. Failure to do this step 1476 can result in a significant reduction in the functionality of the 1477 system. Attempting to do it by hand is not recommended and those 1478 that pursue this avenue should read this file carefully, as well 1479 as the archives of freebsd-current and freebsd-hackers mailing lists 1480 for potential gotchas. The -U option is also useful to consider. 1481 See mergemaster(8) for more information. 1482 1483 [5] Usually this step is a noop. However, from time to time 1484 you may need to do this if you get unknown user in the following 1485 step. It never hurts to do it all the time. You may need to 1486 install a new mergemaster (cd src/usr.sbin/mergemaster && make 1487 install) after the buildworld before this step if you last updated 1488 from current before 20130425 or from -stable before 20130430. 1489 1490 [6] This only deletes old files and directories. Old libraries 1491 can be deleted by "make delete-old-libs", but you have to make 1492 sure that no program is using those libraries anymore. 1493 1494 [8] In order to have a kernel that can run the 4.x binaries needed to 1495 do an installworld, you must include the COMPAT_FREEBSD4 option in 1496 your kernel. Failure to do so may leave you with a system that is 1497 hard to boot to recover. A similar kernel option COMPAT_FREEBSD5 is 1498 required to run the 5.x binaries on more recent kernels. And so on 1499 for COMPAT_FREEBSD6 and COMPAT_FREEBSD7. 1500 1501 Make sure that you merge any new devices from GENERIC since the 1502 last time you updated your kernel config file. 1503 1504 [9] When checking out sources, you must include the -P flag to have 1505 cvs prune empty directories. 1506 1507 If CPUTYPE is defined in your /etc/make.conf, make sure to use the 1508 "?=" instead of the "=" assignment operator, so that buildworld can 1509 override the CPUTYPE if it needs to. 1510 1511 MAKEOBJDIRPREFIX must be defined in an environment variable, and 1512 not on the command line, or in /etc/make.conf. buildworld will 1513 warn if it is improperly defined. 1514FORMAT: 1515 1516This file contains a list, in reverse chronological order, of major 1517breakages in tracking -current. It is not guaranteed to be a complete 1518list of such breakages, and only contains entries since September 23, 2011. 1519If you need to see UPDATING entries from before that date, you will need 1520to fetch an UPDATING file from an older FreeBSD release. 1521 1522Copyright information: 1523 1524Copyright 1998-2009 M.
