These instructions assume that you 6215990Sjmallettbasically know what you are doing. If not, then please consult the FreeBSD 7215990Sjmalletthandbook: 8215990Sjmallett 9210284Sjmallett http://www.freebsd.org/doc/en_US.ISO8859-1/books/handbook/makeworld.html 10215990Sjmallett 11215990SjmallettItems affecting the ports and packages system can be found in 12210284Sjmallett/usr/ports/UPDATING. Please read that file before running portupgrade. 13215990Sjmallett 14215990SjmallettNOTE: FreeBSD has switched from gcc to clang. If you have trouble bootstrapping 15215990Sjmallettfrom older versions of FreeBSD, try WITHOUT_CLANG and WITH_GCC to bootstrap to 16215990Sjmallettthe tip of head, and then rebuild without this option. The bootstrap process 17215990Sjmallettfrom older version of current across the gcc/clang cutover is a bit fragile. 18215990Sjmallett 19215990SjmallettNOTE TO PEOPLE WHO THINK THAT FreeBSD 11.x IS SLOW: 20215990Sjmallett FreeBSD 11.x has many debugging features turned on, in both the kernel 21215990Sjmallett and userland. These features attempt to detect incorrect use of 22215990Sjmallett system primitives, and encourage loud failure through extra sanity 23215990Sjmallett checking and fail stop semantics. They also substantially impact 24215990Sjmallett system performance. If you want to do performance measurement, 25215990Sjmallett benchmarking, and optimization, you'll want to turn them off. This 26215990Sjmallett includes various WITNESS- related kernel options, INVARIANTS, malloc 27215990Sjmallett debugging flags in userland, and various verbose features in the 28215990Sjmallett kernel. Many developers choose to disable these features on build 29215990Sjmallett machines to maximize performance. (To completely disable malloc 30215990Sjmallett debugging, define MALLOC_PRODUCTION in /etc/make.conf, or to merely 31215990Sjmallett disable the most expensive debugging functionality run 32215990Sjmallett "ln -s 'abort:false,junk:false' /etc/malloc.conf".) 33215990Sjmallett 34215990Sjmallett20151030: 35215990Sjmallett The OpenSSL has been upgraded to 1.0.2d. Any binaries requiring 36215990Sjmallett libcrypto.so.7 or libssl.so.7 must be recompiled. 37215990Sjmallett 38210284Sjmallett20151020: 39210284Sjmallett Qlogic 24xx/25xx firmware images were updated from 5.5.0 to 7.3.0. 40210284Sjmallett Kernel modules isp_2400_multi and isp_2500_multi were removed and 41210284Sjmallett should be replaced with isp_2400 and isp_2500 modules respectively. 42210284Sjmallett 43210284Sjmallett20151017: 44210284Sjmallett The build previously allowed using 'make -n' to not recurse into 45215990Sjmallett sub-directories while showing what commands would be executed, and 46210284Sjmallett 'make -n -n' to recursively show commands. Now 'make -n' will recurse 47210284Sjmallett and 'make -N' will not. 48210284Sjmallett 49210284Sjmallett20151012: 50210284Sjmallett If you specify SENDMAIL_MC or SENDMAIL_CF in make.conf, mergemaster 51210284Sjmallett and etcupdate will now use this file. A custom sendmail.cf is now 52215990Sjmallett updated via this mechanism rather than via installworld. If you had 53210284Sjmallett excluded sendmail.cf in mergemaster.rc or etcupdate.conf, you may 54210284Sjmallett want to remove the exclusion or change it to "always install". 55210284Sjmallett /etc/mail/sendmail.cf is now managed the same way regardless of 56210284Sjmallett whether SENDMAIL_MC/SENDMAIL_CF is used. If you are not using 57210284Sjmallett SENDMAIL_MC/SENDMAIL_CF there should be no change in behavior. 58210284Sjmallett 59210284Sjmallett20151011: 60210284Sjmallett Compatibility shims for legacy ATA device names have been removed. 61210284Sjmallett It includes ATA_STATIC_ID kernel option, kern.cam.ada.legacy_aliases 62210284Sjmallett and kern.geom.raid.legacy_aliases loader tunables, kern.devalias.* 63210284Sjmallett environment variables, /dev/ad* and /dev/ar* symbolic links. 64210284Sjmallett 65210284Sjmallett20151006: 66210284Sjmallett Clang, llvm, lldb, compiler-rt and libc++ have been upgraded to 3.7.0. 67210284Sjmallett Please see the 20141231 entry below for information about prerequisites 68210284Sjmallett and upgrading, if you are not already using clang 3.5.0 or higher. 69210284Sjmallett 70210284Sjmallett20150924: 71210284Sjmallett Kernel debug files have been moved to /usr/lib/debug/boot/kernel/, 72210284Sjmallett and renamed from .symbols to .debug. This reduces the size requirements 73210284Sjmallett on the boot partition or file system and provides consistency with 74210284Sjmallett userland debug files. 75210284Sjmallett 76210284Sjmallett When using the supported kernel installation method the 77210284Sjmallett /usr/lib/debug/boot/kernel directory will be renamed (to kernel.old) 78210284Sjmallett as is done with /boot/kernel. 79210284Sjmallett 80210284Sjmallett Developers wishing to maintain the historical behavior of installing 81210284Sjmallett debug files in /boot/kernel/ can set KERN_DEBUGDIR="" in src.conf(5). 82210284Sjmallett 83210284Sjmallett20150827: 84210284Sjmallett The wireless drivers had undergone changes that remove the 'parent 85210284Sjmallett interface' from the ifconfig -l output. The rc.d network scripts 86210284Sjmallett used to check presence of a parent interface in the list, so old 87210284Sjmallett scripts would fail to start wireless networking. Thus, etcupdate(3) 88210284Sjmallett or mergemaster(8) run is required after kernel update, to update your 89210284Sjmallett rc.d scripts in /etc. 90210284Sjmallett 91210284Sjmallett20150827: 92210284Sjmallett pf no longer supports 'scrub fragment crop' or 'scrub fragment drop-ovl' 93210284Sjmallett These configurations are now automatically interpreted as 94210284Sjmallett 'scrub fragment reassemble'. 95210284Sjmallett 96210284Sjmallett20150817: 97210284Sjmallett Kernel-loadable modules for the random(4) device are back. To use 98210284Sjmallett them, the kernel must have 99210284Sjmallett 100210284Sjmallett device random 101210284Sjmallett options RANDOM_LOADABLE 102210284Sjmallett 103210284Sjmallett kldload(8) can then be used to load random_fortuna.ko 104210284Sjmallett or random_yarrow.ko. Please note that due to the indirect 105210284Sjmallett function calls that the loadable modules need to provide, 106210284Sjmallett the build-in variants will be slightly more efficient. 107210284Sjmallett 108210284Sjmallett The random(4) kernel option RANDOM_DUMMY has been retired due to 109210284Sjmallett unpopularity. It was not all that useful anyway. 110210284Sjmallett 111210284Sjmallett20150813: 112210284Sjmallett The WITHOUT_ELFTOOLCHAIN_TOOLS src.conf(5) knob has been retired. 113210284Sjmallett Control over building the ELF Tool Chain tools is now provided by 114210284Sjmallett the WITHOUT_TOOLCHAIN knob. 115210284Sjmallett 116210284Sjmallett20150810: 117210284Sjmallett The polarity of Pulse Per Second (PPS) capture events with the 118210284Sjmallett uart(4) driver has been corrected. Prior to this change the PPS 119210284Sjmallett "assert" event corresponded to the trailing edge of a positive PPS 120210284Sjmallett pulse and the "clear" event was the leading edge of the next pulse. 121210284Sjmallett 122210284Sjmallett As the width of a PPS pulse in a typical GPS receiver is on the 123210284Sjmallett order of 1 millisecond, most users will not notice any significant 124210284Sjmallett difference with this change. 125210284Sjmallett 126 Anyone who has compensated for the historical polarity reversal by 127 configuring a negative offset equal to the pulse width will need to 128 remove that workaround. 129 13020150809: 131 The default group assigned to /dev/dri entries has been changed 132 from 'wheel' to 'video' with the id of '44'. If you want to have 133 access to the dri devices please add yourself to the video group 134 with: 135 136 # pw groupmod video -m $USER 137 13820150806: 139 The menu.rc and loader.rc files will now be replaced during 140 upgrades. Please migrate local changes to menu.rc.local and 141 loader.rc.local instead. 142 14320150805: 144 GNU Binutils versions of addr2line, c++filt, nm, readelf, size, 145 strings and strip have been removed. The src.conf(5) knob 146 WITHOUT_ELFTOOLCHAIN_TOOLS no longer provides the binutils tools. 147 14820150728: 149 As ZFS requires more kernel stack pages than is the default on some 150 architectures e.g. i386, it now warns if KSTACK_PAGES is less than 151 ZFS_MIN_KSTACK_PAGES (which is 4 at the time of writing). 152 153 Please consider using 'options KSTACK_PAGES=X' where X is greater 154 than or equal to ZFS_MIN_KSTACK_PAGES i.e. 4 in such configurations. 155 15620150706: 157 sendmail has been updated to 8.15.2. Starting with FreeBSD 11.0 158 and sendmail 8.15, sendmail uses uncompressed IPv6 addresses by 159 default, i.e., they will not contain "::". For example, instead 160 of ::1, it will be 0:0:0:0:0:0:0:1. This permits a zero subnet 161 to have a more specific match, such as different map entries for 162 IPv6:0:0 vs IPv6:0. This change requires that configuration 163 data (including maps, files, classes, custom ruleset, etc.) must 164 use the same format, so make certain such configuration data is 165 upgrading. As a very simple check search for patterns like 166 'IPv6:[0-9a-fA-F:]*::' and 'IPv6::'. To return to the old 167 behavior, set the m4 option confUSE_COMPRESSED_IPV6_ADDRESSES or 168 the cf option UseCompressedIPv6Addresses. 169 17020150630: 171 The default kernel entropy-processing algorithm is now 172 Fortuna, replacing Yarrow. 173 174 Assuming you have 'device random' in your kernel config 175 file, the configurations allow a kernel option to override 176 this default. You may choose *ONE* of: 177 178 options RANDOM_YARROW # Legacy /dev/random algorithm. 179 options RANDOM_DUMMY # Blocking-only driver. 180 181 If you have neither, you get Fortuna. For most people, 182 read no further, Fortuna will give a /dev/random that works 183 like it always used to, and the difference will be irrelevant. 184 185 If you remove 'device random', you get *NO* kernel-processed 186 entopy at all. This may be acceptable to folks building 187 embedded systems, but has complications. Carry on reading, 188 and it is assumed you know what you need. 189 190 *PLEASE* read random(4) and random(9) if you are in the 191 habit of tweeking kernel configs, and/or if you are a member 192 of the embedded community, wanting specific and not-usual 193 behaviour from your security subsystems. 194 195 NOTE!! If you use RANDOM_DUMMY and/or have no 'device 196 random', you will NOT have a functioning /dev/random, and 197 many cryptographic features will not work, including SSH. 198 You may also find strange behaviour from the random(3) set 199 of library functions, in particular sranddev(3), srandomdev(3) 200 and arc4random(3). The reason for this is that the KERN_ARND 201 sysctl only returns entropy if it thinks it has some to 202 share, and with RANDOM_DUMMY or no 'device random' this 203 will never happen. 204 20520150623: 206 An additional fix for the issue described in the 20150614 sendmail 207 entry below has been been committed in revision 284717. 208 20920150616: 210 FreeBSD's old make (fmake) has been removed from the system. It is 211 available as the devel/fmake port or via pkg install fmake. 212 21320150615: 214 The fix for the issue described in the 20150614 sendmail entry 215 below has been been committed in revision 284436. The work 216 around described in that entry is no longer needed unless the 217 default setting is overridden by a confDH_PARAMETERS configuration 218 setting of '5' or pointing to a 512 bit DH parameter file. 219 22020150614: 221 ALLOW_DEPRECATED_ATF_TOOLS/ATFFILE support has been removed from 222 atf.test.mk (included from bsd.test.mk). Please upgrade devel/atf 223 and devel/kyua to version 0.20+ and adjust any calling code to work 224 with Kyuafile and kyua. 225 22620150614: 227 The import of openssl to address the FreeBSD-SA-15:10.openssl 228 security advisory includes a change which rejects handshakes 229 with DH parameters below 768 bits. sendmail releases prior 230 to 8.15.2 (not yet released), defaulted to a 512 bit 231 DH parameter setting for client connections. To work around 232 this interoperability, sendmail can be configured to use a 233 2048 bit DH parameter by: 234 235 1. Edit /etc/mail/`hostname`.mc 236 2. If a setting for confDH_PARAMETERS does not exist or 237 exists and is set to a string beginning with '5', 238 replace it with '2'. 239 3. If a setting for confDH_PARAMETERS exists and is set to 240 a file path, create a new file with: 241 openssl dhparam -out /path/to/file 2048 242 4. Rebuild the .cf file: 243 cd /etc/mail/; make; make install 244 5. Restart sendmail: 245 cd /etc/mail/; make restart 246 247 A sendmail patch is coming, at which time this file will be 248 updated. 249 25020150604: 251 Generation of legacy formatted entries have been disabled by default 252 in pwd_mkdb(8), as all base system consumers of the legacy formatted 253 entries were converted to use the new format by default when the new, 254 machine independent format have been added and supported since FreeBSD 255 5.x. 256 257 Please see the pwd_mkdb(8) manual page for further details. 258 25920150525: 260 Clang and llvm have been upgraded to 3.6.1 release. Please see the 261 20141231 entry below for information about prerequisites and upgrading, 262 if you are not already using 3.5.0 or higher. 263 26420150521: 265 TI platform code switched to using vendor DTS files and this update 266 may break existing systems running on Beaglebone, Beaglebone Black, 267 and Pandaboard: 268 269 - dtb files should be regenerated/reinstalled. Filenames are the 270 same but content is different now 271 - GPIO addressing was changed, now each GPIO bank (32 pins per bank) 272 has its own /dev/gpiocX device, e.g. pin 121 on /dev/gpioc0 in old 273 addressing scheme is now pin 25 on /dev/gpioc3. 274 - Pandaboard: /etc/ttys should be updated, serial console device is 275 now /dev/ttyu2, not /dev/ttyu0 276 27720150501: 278 soelim(1) from gnu/usr.bin/groff has been replaced by usr.bin/soelim. 279 If you need the GNU extension from groff soelim(1), install groff 280 from package: pkg install groff, or via ports: textproc/groff. 281 28220150423: 283 chmod, chflags, chown and chgrp now affect symlinks in -R mode as 284 defined in symlink(7); previously symlinks were silently ignored. 285 28620150415: 287 The const qualifier has been removed from iconv(3) to comply with 288 POSIX. The ports tree is aware of this from r384038 onwards. 289 29020150416: 291 Libraries specified by LIBADD in Makefiles must have a corresponding 292 DPADD_<lib> variable to ensure correct dependencies. This is now 293 enforced in src.libnames.mk. 294 29520150324: 296 From legacy ata(4) driver was removed support for SATA controllers 297 supported by more functional drivers ahci(4), siis(4) and mvs(4). 298 Kernel modules ataahci and ataadaptec were removed completely, 299 replaced by ahci and mvs modules respectively. 300 30120150315: 302 Clang, llvm and lldb have been upgraded to 3.6.0 release. Please see 303 the 20141231 entry below for information about prerequisites and 304 upgrading, if you are not already using 3.5.0 or higher. 305 30620150307: 307 The 32-bit PowerPC kernel has been changed to a position-independent 308 executable. This can only be booted with a version of loader(8) 309 newer than January 31, 2015, so make sure to update both world and 310 kernel before rebooting. 311 31220150217: 313 If you are running a -CURRENT kernel since r273872 (Oct 30th, 2014), 314 but before r278950, the RNG was not seeded properly. Immediately 315 upgrade the kernel to r278950 or later and regenerate any keys (e.g. 316 ssh keys or openssl keys) that were generated w/ a kernel from that 317 range. This does not affect programs that directly used /dev/random 318 or /dev/urandom. All userland uses of arc4random(3) are affected. 319 32020150210: 321 The autofs(4) ABI was changed in order to restore binary compatibility 322 with 10.1-RELEASE. The automountd(8) daemon needs to be rebuilt to work 323 with the new kernel. 324 32520150131: 326 The powerpc64 kernel has been changed to a position-independent 327 executable. This can only be booted with a new version of loader(8), 328 so make sure to update both world and kernel before rebooting. 329 33020150118: 331 Clang and llvm have been upgraded to 3.5.1 release. This is a bugfix 332 only release, no new features have been added. Please see the 20141231 333 entry below for information about prerequisites and upgrading, if you 334 are not already using 3.5.0. 335 33620150107: 337 ELF tools addr2line, elfcopy (strip), nm, size, and strings are now 338 taken from the ELF Tool Chain project rather than GNU binutils. They 339 should be drop-in replacements, with the addition of arm64 support. 340 The WITHOUT_ELFTOOLCHAIN_TOOLS= knob may be used to obtain the 341 binutils tools, if necessary. See 20150805 for updated information. 342 34320150105: 344 The default Unbound configuration now enables remote control 345 using a local socket. Users who have already enabled the 346 local_unbound service should regenerate their configuration 347 by running "service local_unbound setup" as root. 348 34920150102: 350 The GNU texinfo and GNU info pages have been removed. 351 To be able to view GNU info pages please install texinfo from ports. 352 35320141231: 354 Clang, llvm and lldb have been upgraded to 3.5.0 release. 355 356 As of this release, a prerequisite for building clang, llvm and lldb is 357 a C++11 capable compiler and C++11 standard library. This means that to 358 be able to successfully build the cross-tools stage of buildworld, with 359 clang as the bootstrap compiler, your system compiler or cross compiler 360 should either be clang 3.3 or later, or gcc 4.8 or later, and your 361 system C++ library should be libc++, or libdstdc++ from gcc 4.8 or 362 later. 363 364 On any standard FreeBSD 10.x or 11.x installation, where clang and 365 libc++ are on by default (that is, on x86 or arm), this should work out 366 of the box. 367 368 On 9.x installations where clang is enabled by default, e.g. on x86 and 369 powerpc, libc++ will not be enabled by default, so libc++ should be 370 built (with clang) and installed first. If both clang and libc++ are 371 missing, build clang first, then use it to build libc++. 372 373 On 8.x and earlier installations, upgrade to 9.x first, and then follow 374 the instructions for 9.x above. 375 376 Sparc64 and mips users are unaffected, as they still use gcc 4.2.1 by 377 default, and do not build clang. 378 379 Many embedded systems are resource constrained, and will not be able to 380 build clang in a reasonable time, or in some cases at all. In those 381 cases, cross building bootable systems on amd64 is a workaround. 382 383 This new version of clang introduces a number of new warnings, of which 384 the following are most likely to appear: 385 386 -Wabsolute-value 387 388 This warns in two cases, for both C and C++: 389 * When the code is trying to take the absolute value of an unsigned 390 quantity, which is effectively a no-op, and almost never what was 391 intended. The code should be fixed, if at all possible. If you are 392 sure that the unsigned quantity can be safely cast to signed, without 393 loss of information or undefined behavior, you can add an explicit 394 cast, or disable the warning. 395 396 * When the code is trying to take an absolute value, but the called 397 abs() variant is for the wrong type, which can lead to truncation. 398 If you want to disable the warning instead of fixing the code, please 399 make sure that truncation will not occur, or it might lead to unwanted 400 side-effects. 401 402 -Wtautological-undefined-compare and 403 -Wundefined-bool-conversion 404 405 These warn when C++ code is trying to compare 'this' against NULL, while 406 'this' should never be NULL in well-defined C++ code. However, there is 407 some legacy (pre C++11) code out there, which actively abuses this 408 feature, which was less strictly defined in previous C++ versions. 409 410 Squid and openjdk do this, for example. The warning can be turned off 411 for C++98 and earlier, but compiling the code in C++11 mode might result 412 in unexpected behavior; for example, the parts of the program that are 413 unreachable could be optimized away. 414 41520141222: 416 The old NFS client and server (kernel options NFSCLIENT, NFSSERVER) 417 kernel sources have been removed. The .h files remain, since some 418 utilities include them. This will need to be fixed later. 419 If "mount -t oldnfs ..." is attempted, it will fail. 420 If the "-o" option on mountd(8), nfsd(8) or nfsstat(1) is used, 421 the utilities will report errors. 422 42320141121: 424 The handling of LOCAL_LIB_DIRS has been altered to skip addition of 425 directories to top level SUBDIR variable when their parent 426 directory is included in LOCAL_DIRS. Users with build systems with 427 such hierarchies and without SUBDIR entries in the parent 428 directory Makefiles should add them or add the directories to 429 LOCAL_DIRS. 430 43120141109: 432 faith(4) and faithd(8) have been removed from the base system. Faith 433 has been obsolete for a very long time. 434 43520141104: 436 vt(4), the new console driver, is enabled by default. It brings 437 support for Unicode and double-width characters, as well as 438 support for UEFI and integration with the KMS kernel video 439 drivers. 440 441 You may need to update your console settings in /etc/rc.conf, 442 most probably the keymap. During boot, /etc/rc.d/syscons will 443 indicate what you need to do. 444 445 vt(4) still has issues and lacks some features compared to 446 syscons(4). See the wiki for up-to-date information: 447 https://wiki.freebsd.org/Newcons 448 449 If you want to keep using syscons(4), you can do so by adding 450 the following line to /boot/loader.conf: 451 kern.vty=sc 452 45320141102: 454 pjdfstest has been integrated into kyua as an opt-in test suite. 455 Please see share/doc/pjdfstest/README for more details on how to 456 execute it. 457 45820141009: 459 gperf has been removed from the base system for architectures 460 that use clang. Ports that require gperf will obtain it from the 461 devel/gperf port. 462 46320140923: 464 pjdfstest has been moved from tools/regression/pjdfstest to 465 contrib/pjdfstest . 466 46720140922: 468 At svn r271982, The default linux compat kernel ABI has been adjusted 469 to 2.6.18 in support of the linux-c6 compat ports infrastructure 470 update. If you wish to continue using the linux-f10 compat ports, 471 add compat.linux.osrelease=2.6.16 to your local sysctl.conf. Users are 472 encouraged to update their linux-compat packages to linux-c6 during 473 their next update cycle. 474 47520140729: 476 The ofwfb driver, used to provide a graphics console on PowerPC when 477 using vt(4), no longer allows mmap() of all physical memory. This 478 will prevent Xorg on PowerPC with some ATI graphics cards from 479 initializing properly unless x11-servers/xorg-server is updated to 480 1.12.4_8 or newer. 481 48220140723: 483 The xdev targets have been converted to using TARGET and 484 TARGET_ARCH instead of XDEV and XDEV_ARCH. 485 48620140719: 487 The default unbound configuration has been modified to address 488 issues with reverse lookups on networks that use private 489 address ranges. If you use the local_unbound service, run 490 "service local_unbound setup" as root to regenerate your 491 configuration, then "service local_unbound reload" to load the 492 new configuration. 493 49420140709: 495 The GNU texinfo and GNU info pages are not built and installed 496 anymore, WITH_INFO knob has been added to allow to built and install 497 them again. 498 UPDATE: see 20150102 entry on texinfo's removal 499 50020140708: 501 The GNU readline library is now an INTERNALLIB - that is, it is 502 statically linked into consumers (GDB and variants) in the base 503 system, and the shared library is no longer installed. The 504 devel/readline port is available for third party software that 505 requires readline. 506 50720140702: 508 The Itanium architecture (ia64) has been removed from the list of 509 known architectures. This is the first step in the removal of the 510 architecture. 511 51220140701: 513 Commit r268115 has added NFSv4.1 server support, merged from 514 projects/nfsv4.1-server. Since this includes changes to the 515 internal interfaces between the NFS related modules, a full 516 build of the kernel and modules will be necessary. 517 __FreeBSD_version has been bumped. 518 51920140629: 520 The WITHOUT_VT_SUPPORT kernel config knob has been renamed 521 WITHOUT_VT. (The other _SUPPORT knobs have a consistent meaning 522 which differs from the behaviour controlled by this knob.) 523 52420140619: 525 Maximal length of the serial number in CTL was increased from 16 to 526 64 chars, that breaks ABI. All CTL-related tools, such as ctladm 527 and ctld, need to be rebuilt to work with a new kernel. 528 52920140606: 530 The libatf-c and libatf-c++ major versions were downgraded to 0 and 531 1 respectively to match the upstream numbers. They were out of 532 sync because, when they were originally added to FreeBSD, the 533 upstream versions were not respected. These libraries are private 534 and not yet built by default, so renumbering them should be a 535 non-issue. However, unclean source trees will yield broken test 536 programs once the operator executes "make delete-old-libs" after a 537 "make installworld". 538 539 Additionally, the atf-sh binary was made private by moving it into 540 /usr/libexec/. Already-built shell test programs will keep the 541 path to the old binary so they will break after "make delete-old" 542 is run. 543 544 If you are using WITH_TESTS=yes (not the default), wipe the object 545 tree and rebuild from scratch to prevent spurious test failures. 546 This is only needed once: the misnumbered libraries and misplaced 547 binaries have been added to OptionalObsoleteFiles.inc so they will 548 be removed during a clean upgrade. 549 55020140512: 551 Clang and llvm have been upgraded to 3.4.1 release. 552 55320140508: 554 We bogusly installed src.opts.mk in /usr/share/mk. This file should 555 be removed to avoid issues in the future (and has been added to 556 ObsoleteFiles.inc). 557 55820140505: 559 /etc/src.conf now affects only builds of the FreeBSD src tree. In the 560 past, it affected all builds that used the bsd.*.mk files. The old 561 behavior was a bug, but people may have relied upon it. To get this 562 behavior back, you can .include /etc/src.conf from /etc/make.conf 563 (which is still global and isn't changed). This also changes the 564 behavior of incremental builds inside the tree of individual 565 directories. Set MAKESYSPATH to ".../share/mk" to do that. 566 Although this has survived make universe and some upgrade scenarios, 567 other upgrade scenarios may have broken. At least one form of 568 temporary breakage was fixed with MAKESYSPATH settings for buildworld 569 as well... In cases where MAKESYSPATH isn't working with this 570 setting, you'll need to set it to the full path to your tree. 571 572 One side effect of all this cleaning up is that bsd.compiler.mk 573 is no longer implicitly included by bsd.own.mk. If you wish to 574 use COMPILER_TYPE, you must now explicitly include bsd.compiler.mk 575 as well. 576 57720140430: 578 The lindev device has been removed since /dev/full has been made a 579 standard device. __FreeBSD_version has been bumped. 580 58120140424: 582 The knob WITHOUT_VI was added to the base system, which controls 583 building ex(1), vi(1), etc. Older releases of FreeBSD required ex(1) 584 in order to reorder files share/termcap and didn't build ex(1) as a 585 build tool, so building/installing with WITH_VI is highly advised for 586 build hosts for older releases. 587 588 This issue has been fixed in stable/9 and stable/10 in r277022 and 589 r276991, respectively. 590 59120140418: 592 The YES_HESIOD knob has been removed. It has been obsolete for 593 a decade. Please move to using WITH_HESIOD instead or your builds 594 will silently lack HESIOD. 595 59620140405: 597 The uart(4) driver has been changed with respect to its handling 598 of the low-level console. Previously the uart(4) driver prevented 599 any process from changing the baudrate or the CLOCAL and HUPCL 600 control flags. By removing the restrictions, operators can make 601 changes to the serial console port without having to reboot. 602 However, when getty(8) is started on the serial device that is 603 associated with the low-level console, a misconfigured terminal 604 line in /etc/ttys will now have a real impact. 605 Before upgrading the kernel, make sure that /etc/ttys has the 606 serial console device configured as 3wire without baudrate to 607 preserve the previous behaviour. E.g: 608 ttyu0 "/usr/libexec/getty 3wire" vt100 on secure 609 61020140306: 611 Support for libwrap (TCP wrappers) in rpcbind was disabled by default 612 to improve performance. To re-enable it, if needed, run rpcbind 613 with command line option -W. 614 61520140226: 616 Switched back to the GPL dtc compiler due to updates in the upstream 617 dts files not being supported by the BSDL dtc compiler. You will need 618 to rebuild your kernel toolchain to pick up the new compiler. Core dumps 619 may result while building dtb files during a kernel build if you fail 620 to do so. Set WITHOUT_GPL_DTC if you require the BSDL compiler. 621 62220140216: 623 Clang and llvm have been upgraded to 3.4 release. 624 62520140216: 626 The nve(4) driver has been removed. Please use the nfe(4) driver 627 for NVIDIA nForce MCP Ethernet adapters instead. 628 62920140212: 630 An ABI incompatibility crept into the libc++ 3.4 import in r261283. 631 This could cause certain C++ applications using shared libraries built 632 against the previous version of libc++ to crash. The incompatibility 633 has now been fixed, but any C++ applications or shared libraries built 634 between r261283 and r261801 should be recompiled. 635 63620140204: 637 OpenSSH will now ignore errors caused by kernel lacking of Capsicum 638 capability mode support. Please note that enabling the feature in 639 kernel is still highly recommended. 640 64120140131: 642 OpenSSH is now built with sandbox support, and will use sandbox as 643 the default privilege separation method. This requires Capsicum 644 capability mode support in kernel. 645 64620140128: 647 The libelf and libdwarf libraries have been updated to newer 648 versions from upstream. Shared library version numbers for 649 these two libraries were bumped. Any ports or binaries 650 requiring these two libraries should be recompiled. 651 __FreeBSD_version is bumped to 1100006. 652 65320140110: 654 If a Makefile in a tests/ directory was auto-generating a Kyuafile 655 instead of providing an explicit one, this would prevent such 656 Makefile from providing its own Kyuafile in the future during 657 NO_CLEAN builds. This has been fixed in the Makefiles but manual 658 intervention is needed to clean an objdir if you use NO_CLEAN: 659 # find /usr/obj -name Kyuafile | xargs rm -f 660 66120131213: 662 The behavior of gss_pseudo_random() for the krb5 mechanism 663 has changed, for applications requesting a longer random string 664 than produced by the underlying enctype's pseudo-random() function. 665 In particular, the random string produced from a session key of 666 enctype aes256-cts-hmac-sha1-96 or aes256-cts-hmac-sha1-96 will 667 be different at the 17th octet and later, after this change. 668 The counter used in the PRF+ construction is now encoded as a 669 big-endian integer in accordance with RFC 4402. 670 __FreeBSD_version is bumped to 1100004. 671 67220131108: 673 The WITHOUT_ATF build knob has been removed and its functionality 674 has been subsumed into the more generic WITHOUT_TESTS. If you were 675 using the former to disable the build of the ATF libraries, you 676 should change your settings to use the latter. 677 67820131025: 679 The default version of mtree is nmtree which is obtained from 680 NetBSD. The output is generally the same, but may vary 681 slightly. If you found you need identical output adding 682 "-F freebsd9" to the command line should do the trick. For the 683 time being, the old mtree is available as fmtree. 684 68520131014: 686 libbsdyml has been renamed to libyaml and moved to /usr/lib/private. 687 This will break ports-mgmt/pkg. Rebuild the port, or upgrade to pkg 688 1.1.4_8 and verify bsdyml not linked in, before running "make 689 delete-old-libs": 690 # make -C /usr/ports/ports-mgmt/pkg build deinstall install clean 691 or 692 # pkg install pkg; ldd /usr/local/sbin/pkg | grep bsdyml 693 69420131010: 695 The stable/10 branch has been created in subversion from head 696 revision r256279. 697 69820131010: 699 The rc.d/jail script has been updated to support jail(8) 700 configuration file. The "jail_<jname>_*" rc.conf(5) variables 701 for per-jail configuration are automatically converted to 702 /var/run/jail.<jname>.conf before the jail(8) utility is invoked. 703 This is transparently backward compatible. See below about some 704 incompatibilities and rc.conf(5) manual page for more details. 705 706 These variables are now deprecated in favor of jail(8) configuration 707 file. One can use "rc.d/jail config <jname>" command to generate 708 a jail(8) configuration file in /var/run/jail.<jname>.conf without 709 running the jail(8) utility. The default pathname of the 710 configuration file is /etc/jail.conf and can be specified by 711 using $jail_conf or $jail_<jname>_conf variables. 712 713 Please note that jail_devfs_ruleset accepts an integer at 714 this moment. Please consider to rewrite the ruleset name 715 with an integer. 716 71720130930: 718 BIND has been removed from the base system. If all you need 719 is a local resolver, simply enable and start the local_unbound 720 service instead. Otherwise, several versions of BIND are 721 available in the ports tree. The dns/bind99 port is one example. 722 723 With this change, nslookup(1) and dig(1) are no longer in the base 724 system. Users should instead use host(1) and drill(1) which are 725 in the base system. Alternatively, nslookup and dig can 726 be obtained by installing the dns/bind-tools port. 727 72820130916: 729 With the addition of unbound(8), a new unbound user is now 730 required during installworld. "mergemaster -p" can be used to 731 add the user prior to installworld, as documented in the handbook. 732 73320130911: 734 OpenSSH is now built with DNSSEC support, and will by default 735 silently trust signed SSHFP records. This can be controlled with 736 the VerifyHostKeyDNS client configuration setting. DNSSEC support 737 can be disabled entirely with the WITHOUT_LDNS option in src.conf. 738 73920130906: 740 The GNU Compiler Collection and C++ standard library (libstdc++) 741 are no longer built by default on platforms where clang is the system 742 compiler. You can enable them with the WITH_GCC and WITH_GNUCXX 743 options in src.conf. 744 74520130905: 746 The PROCDESC kernel option is now part of the GENERIC kernel 747 configuration and is required for the rwhod(8) to work. 748 If you are using custom kernel configuration, you should include 749 'options PROCDESC'. 750 75120130905: 752 The API and ABI related to the Capsicum framework was modified 753 in backward incompatible way. The userland libraries and programs 754 have to be recompiled to work with the new kernel. This includes the 755 following libraries and programs, but the whole buildworld is 756 advised: libc, libprocstat, dhclient, tcpdump, hastd, hastctl, 757 kdump, procstat, rwho, rwhod, uniq. 758 75920130903: 760 AES-NI intrinsic support has been added to gcc. The AES-NI module 761 has been updated to use this support. A new gcc is required to build 762 the aesni module on both i386 and amd64. 763 76420130821: 765 The PADLOCK_RNG and RDRAND_RNG kernel options are now devices. 766 Thus "device padlock_rng" and "device rdrand_rng" should be 767 used instead of "options PADLOCK_RNG" & "options RDRAND_RNG". 768 76920130813: 770 WITH_ICONV has been split into two feature sets. WITH_ICONV now 771 enables just the iconv* functionality and is now on by default. 772 WITH_LIBICONV_COMPAT enables the libiconv api and link time 773 compatability. Set WITHOUT_ICONV to build the old way. 774 If you have been using WITH_ICONV before, you will very likely 775 need to turn on WITH_LIBICONV_COMPAT. 776 77720130806: 778 INVARIANTS option now enables DEBUG for code with OpenSolaris and 779 Illumos origin, including ZFS. If you have INVARIANTS in your 780 kernel configuration, then there is no need to set DEBUG or ZFS_DEBUG 781 explicitly. 782 DEBUG used to enable witness(9) tracking of OpenSolaris (mostly ZFS) 783 locks if WITNESS option was set. Because that generated a lot of 784 witness(9) reports and all of them were believed to be false 785 positives, this is no longer done. New option OPENSOLARIS_WITNESS 786 can be used to achieve the previous behavior. 787 78820130806: 789 Timer values in IPv6 data structures now use time_uptime instead 790 of time_second. Although this is not a user-visible functional 791 change, userland utilities which directly use them---ndp(8), 792 rtadvd(8), and rtsold(8) in the base system---need to be updated 793 to r253970 or later. 794 79520130802: 796 find -delete can now delete the pathnames given as arguments, 797 instead of only files found below them or if the pathname did 798 not contain any slashes. Formerly, the following error message 799 would result: 800 801 find: -delete: <path>: relative path potentially not safe 802 803 Deleting the pathnames given as arguments can be prevented 804 without error messages using -mindepth 1 or by changing 805 directory and passing "." as argument to find. This works in the 806 old as well as the new version of find. 807 80820130726: 809 Behavior of devfs rules path matching has been changed. 810 Pattern is now always matched against fully qualified devfs 811 path and slash characters must be explicitly matched by 812 slashes in pattern (FNM_PATHNAME). Rulesets involving devfs 813 subdirectories must be reviewed. 814 81520130716: 816 The default ARM ABI has changed to the ARM EABI. The old ABI is 817 incompatible with the ARM EABI and all programs and modules will 818 need to be rebuilt to work with a new kernel. 819 820 To keep using the old ABI ensure the WITHOUT_ARM_EABI knob is set. 821 822 NOTE: Support for the old ABI will be removed in the future and 823 users are advised to upgrade. 824 82520130709: 826 pkg_install has been disconnected from the build if you really need it 827 you should add WITH_PKGTOOLS in your src.conf(5). 828 82920130709: 830 Most of network statistics structures were changed to be able 831 keep 64-bits counters. Thus all tools, that work with networking 832 statistics, must be rebuilt (netstat(1), bsnmpd(1), etc.) 833 83420130629: 835 Fix targets that run multiple make's to use && rather than ; 836 so that subsequent steps depend on success of previous. 837 838 NOTE: if building 'universe' with -j* on stable/8 or stable/9 839 it would be better to start the build using bmake, to avoid 840 overloading the machine. 841 84220130618: 843 Fix a bug that allowed a tracing process (e.g. gdb) to write 844 to a memory-mapped file in the traced process's address space 845 even if neither the traced process nor the tracing process had 846 write access to that file. 847 84820130615: 849 CVS has been removed from the base system. An exact copy 850 of the code is available from the devel/cvs port. 851 85220130613: 853 Some people report the following error after the switch to bmake: 854 855 make: illegal option -- J 856 usage: make [-BPSXeiknpqrstv] [-C directory] [-D variable] 857 ... 858 *** [buildworld] Error code 2 859 860 this likely due to an old instance of make in 861 ${MAKEPATH} (${MAKEOBJDIRPREFIX}${.CURDIR}/make.${MACHINE}) 862 which src/Makefile will use that blindly, if it exists, so if 863 you see the above error: 864 865 rm -rf `make -V MAKEPATH` 866 867 should resolve it. 868 86920130516: 870 Use bmake by default. 871 Whereas before one could choose to build with bmake via 872 -DWITH_BMAKE one must now use -DWITHOUT_BMAKE to use the old 873 make. The goal is to remove these knobs for 10-RELEASE. 874 875 It is worth noting that bmake (like gmake) treats the command 876 line as the unit of failure, rather than statements within the 877 command line. Thus '(cd some/where && dosomething)' is safer 878 than 'cd some/where; dosomething'. The '()' allows consistent 879 behavior in parallel build. 880 88120130429: 882 Fix a bug that allows NFS clients to issue READDIR on files. 883 88420130426: 885 The WITHOUT_IDEA option has been removed because 886 the IDEA patent expired. 887 88820130426: 889 The sysctl which controls TRIM support under ZFS has been renamed 890 from vfs.zfs.trim_disable -> vfs.zfs.trim.enabled and has been 891 enabled by default. 892 89320130425: 894 The mergemaster command now uses the default MAKEOBJDIRPREFIX 895 rather than creating it's own in the temporary directory in 896 order allow access to bootstrapped versions of tools such as 897 install and mtree. When upgrading from version of FreeBSD where 898 the install command does not support -l, you will need to 899 install a new mergemaster command if mergemaster -p is required. 900 This can be accomplished with the command (cd src/usr.sbin/mergemaster 901 && make install). 902 90320130404: 904 Legacy ATA stack, disabled and replaced by new CAM-based one since 905 FreeBSD 9.0, completely removed from the sources. Kernel modules 906 atadisk and atapi*, user-level tools atacontrol and burncd are 907 removed. Kernel option `options ATA_CAM` is now permanently enabled 908 and removed. 909 91020130319: 911 SOCK_CLOEXEC and SOCK_NONBLOCK flags have been added to socket(2) 912 and socketpair(2). Software, in particular Kerberos, may 913 automatically detect and use these during building. The resulting 914 binaries will not work on older kernels. 915 91620130308: 917 CTL_DISABLE has also been added to the sparc64 GENERIC (for further 918 information, see the respective 20130304 entry). 919 92020130304: 921 Recent commits to callout(9) changed the size of struct callout, 922 so the KBI is probably heavily disturbed. Also, some functions 923 in callout(9)/sleep(9)/sleepqueue(9)/condvar(9) KPIs were replaced 924 by macros. Every kernel module using it won't load, so rebuild 925 is requested. 926 927 The ctl device has been re-enabled in GENERIC for i386 and amd64, 928 but does not initialize by default (because of the new CTL_DISABLE 929 option) to save memory. To re-enable it, remove the CTL_DISABLE 930 option from the kernel config file or set kern.cam.ctl.disable=0 931 in /boot/loader.conf. 932 93320130301: 934 The ctl device has been disabled in GENERIC for i386 and amd64. 935 This was done due to the extra memory being allocated at system 936 initialisation time by the ctl driver which was only used if 937 a CAM target device was created. This makes a FreeBSD system 938 unusable on 128MB or less of RAM. 939 94020130208: 941 A new compression method (lz4) has been merged to -HEAD. Please 942 refer to zpool-features(7) for more information. 943 944 Please refer to the "ZFS notes" section of this file for information 945 on upgrading boot ZFS pools. 946 94720130129: 948 A BSD-licensed patch(1) variant has been added and is installed 949 as bsdpatch, being the GNU version the default patch. 950 To inverse the logic and use the BSD-licensed one as default, 951 while having the GNU version installed as gnupatch, rebuild 952 and install world with the WITH_BSD_PATCH knob set. 953 95420130121: 955 Due to the use of the new -l option to install(1) during build 956 and install, you must take care not to directly set the INSTALL 957 make variable in your /etc/make.conf, /etc/src.conf, or on the 958 command line. If you wish to use the -C flag for all installs 959 you may be able to add INSTALL+=-C to /etc/make.conf or 960 /etc/src.conf. 961 96220130118: 963 The install(1) option -M has changed meaning and now takes an 964 argument that is a file or path to append logs to. In the 965 unlikely event that -M was the last option on the command line 966 and the command line contained at least two files and a target 967 directory the first file will have logs appended to it. The -M 968 option served little practical purpose in the last decade so its 969 use is expected to be extremely rare. 970 97120121223: 972 After switching to Clang as the default compiler some users of ZFS 973 on i386 systems started to experience stack overflow kernel panics. 974 Please consider using 'options KSTACK_PAGES=4' in such configurations. 975 97620121222: 977 GEOM_LABEL now mangles label names read from file system metadata. 978 Mangling affect labels containing spaces, non-printable characters, 979 '%' or '"'. Device names in /etc/fstab and other places may need to 980 be updated. 981 98220121217: 983 By default, only the 10 most recent kernel dumps will be saved. To 984 restore the previous behaviour (no limit on the number of kernel dumps 985 stored in the dump directory) add the following line to /etc/rc.conf: 986 987 savecore_flags="" 988 98920121201: 990 With the addition of auditdistd(8), a new auditdistd user is now 991 required during installworld. "mergemaster -p" can be used to 992 add the user prior to installworld, as documented in the handbook. 993 99420121117: 995 The sin6_scope_id member variable in struct sockaddr_in6 is now 996 filled by the kernel before passing the structure to the userland via 997 sysctl or routing socket. This means the KAME-specific embedded scope 998 id in sin6_addr.s6_addr[2] is always cleared in userland application. 999 This behavior can be controlled by net.inet6.ip6.deembed_scopeid. 1000 __FreeBSD_version is bumped to 1000025. 1001 100220121105: 1003 On i386 and amd64 systems WITH_CLANG_IS_CC is now the default. 1004 This means that the world and kernel will be compiled with clang 1005 and that clang will be installed as /usr/bin/cc, /usr/bin/c++, 1006 and /usr/bin/cpp. To disable this behavior and revert to building 1007 with gcc, compile with WITHOUT_CLANG_IS_CC. Really old versions 1008 of current may need to bootstrap WITHOUT_CLANG first if the clang 1009 build fails (its compatibility window doesn't extend to the 9 stable 1010 branch point). 1011 101220121102: 1013 The IPFIREWALL_FORWARD kernel option has been removed. Its 1014 functionality now turned on by default. 1015 101620121023: 1017 The ZERO_COPY_SOCKET kernel option has been removed and 1018 split into SOCKET_SEND_COW and SOCKET_RECV_PFLIP. 1019 NB: SOCKET_SEND_COW uses the VM page based copy-on-write 1020 mechanism which is not safe and may result in kernel crashes. 1021 NB: The SOCKET_RECV_PFLIP mechanism is useless as no current 1022 driver supports disposeable external page sized mbuf storage. 1023 Proper replacements for both zero-copy mechanisms are under 1024 consideration and will eventually lead to complete removal 1025 of the two kernel options. 1026 102720121023: 1028 The IPv4 network stack has been converted to network byte 1029 order. The following modules need to be recompiled together 1030 with kernel: carp(4), divert(4), gif(4), siftr(4), gre(4), 1031 pf(4), ipfw(4), ng_ipfw(4), stf(4). 1032 103320121022: 1034 Support for non-MPSAFE filesystems was removed from VFS. The 1035 VFS_VERSION was bumped, all filesystem modules shall be 1036 recompiled. 1037 103820121018: 1039 All the non-MPSAFE filesystems have been disconnected from 1040 the build. The full list includes: codafs, hpfs, ntfs, nwfs, 1041 portalfs, smbfs, xfs. 1042 104320121016: 1044 The interface cloning API and ABI has changed. The following 1045 modules need to be recompiled together with kernel: 1046 ipfw(4), pfsync(4), pflog(4), usb(4), wlan(4), stf(4), 1047 vlan(4), disc(4), edsc(4), if_bridge(4), gif(4), tap(4), 1048 faith(4), epair(4), enc(4), tun(4), if_lagg(4), gre(4). 1049 105020121015: 1051 The sdhci driver was split in two parts: sdhci (generic SD Host 1052 Controller logic) and sdhci_pci (actual hardware driver). 1053 No kernel config modifications are required, but if you 1054 load sdhc as a module you must switch to sdhci_pci instead. 1055 105620121014: 1057 Import the FUSE kernel and userland support into base system. 1058 105920121013: 1060 The GNU sort(1) program has been removed since the BSD-licensed 1061 sort(1) has been the default for quite some time and no serious 1062 problems have been reported. The corresponding WITH_GNU_SORT 1063 knob has also gone. 1064 106520121006: 1066 The pfil(9) API/ABI for AF_INET family has been changed. Packet 1067 filtering modules: pf(4), ipfw(4), ipfilter(4) need to be recompiled 1068 with new kernel. 1069 107020121001: 1071 The net80211(4) ABI has been changed to allow for improved driver 1072 PS-POLL and power-save support. All wireless drivers need to be 1073 recompiled to work with the new kernel. 1074 107520120913: 1076 The random(4) support for the VIA hardware random number 1077 generator (`PADLOCK') is no longer enabled unconditionally. 1078 Add the padlock_rng device in the custom kernel config if 1079 needed. The GENERIC kernels on i386 and amd64 do include the 1080 device, so the change only affects the custom kernel 1081 configurations. 1082 108320120908: 1084 The pf(4) packet filter ABI has been changed. pfctl(8) and 1085 snmp_pf module need to be recompiled to work with new kernel. 1086 108720120828: 1088 A new ZFS feature flag "com.delphix:empty_bpobj" has been merged 1089 to -HEAD. Pools that have empty_bpobj in active state can not be 1090 imported read-write with ZFS implementations that do not support 1091 this feature. For more information read the zpool-features(5) 1092 manual page. 1093 109420120727: 1095 The sparc64 ZFS loader has been changed to no longer try to auto- 1096 detect ZFS providers based on diskN aliases but now requires these 1097 to be explicitly listed in the OFW boot-device environment variable. 1098 109920120712: 1100 The OpenSSL has been upgraded to 1.0.1c. Any binaries requiring 1101 libcrypto.so.6 or libssl.so.6 must be recompiled. Also, there are 1102 configuration changes. Make sure to merge /etc/ssl/openssl.cnf. 1103 110420120712: 1105 The following sysctls and tunables have been renamed for consistency 1106 with other variables: 1107 kern.cam.da.da_send_ordered -> kern.cam.da.send_ordered 1108 kern.cam.ada.ada_send_ordered -> kern.cam.ada.send_ordered 1109 111020120628: 1111 The sort utility has been replaced with BSD sort. For now, GNU sort 1112 is also available as "gnusort" or the default can be set back to 1113 GNU sort by setting WITH_GNU_SORT. In this case, BSD sort will be 1114 installed as "bsdsort". 1115 111620120611: 1117 A new version of ZFS (pool version 5000) has been merged to -HEAD. 1118 Starting with this version the old system of ZFS pool versioning 1119 is superseded by "feature flags". This concept enables forward 1120 compatibility against certain future changes in functionality of ZFS 1121 pools. The first read-only compatible "feature flag" for ZFS pools 1122 is named "com.delphix:async_destroy". For more information 1123 read the new zpool-features(5) manual page. 1124 Please refer to the "ZFS notes" section of this file for information 1125 on upgrading boot ZFS pools. 1126 112720120417: 1128 The malloc(3) implementation embedded in libc now uses sources imported 1129 as contrib/jemalloc. The most disruptive API change is to 1130 /etc/malloc.conf. If your system has an old-style /etc/malloc.conf, 1131 delete it prior to installworld, and optionally re-create it using the 1132 new format after rebooting. See malloc.conf(5) for details 1133 (specifically the TUNING section and the "opt.*" entries in the MALLCTL 1134 NAMESPACE section). 1135 113620120328: 1137 Big-endian MIPS TARGET_ARCH values no longer end in "eb". mips64eb 1138 is now spelled mips64. mipsn32eb is now spelled mipsn32. mipseb is 1139 now spelled mips. This is to aid compatibility with third-party 1140 software that expects this naming scheme in uname(3). Little-endian 1141 settings are unchanged. If you are updating a big-endian mips64 machine 1142 from before this change, you may need to set MACHINE_ARCH=mips64 in 1143 your environment before the new build system will recognize your machine. 1144 114520120306: 1146 Disable by default the option VFS_ALLOW_NONMPSAFE for all supported 1147 platforms. 1148 114920120229: 1150 Now unix domain sockets behave "as expected" on nullfs(5). Previously 1151 nullfs(5) did not pass through all behaviours to the underlying layer, 1152 as a result if we bound to a socket on the lower layer we could connect 1153 only to the lower path; if we bound to the upper layer we could connect 1154 only to the upper path. The new behavior is one can connect to both the 1155 lower and the upper paths regardless what layer path one binds to. 1156 115720120211: 1158 The getifaddrs upgrade path broken with 20111215 has been restored. 1159 If you have upgraded in between 20111215 and 20120209 you need to 1160 recompile libc again with your kernel. You still need to recompile 1161 world to be able to configure CARP but this restriction already 1162 comes from 20111215. 1163 116420120114: 1165 The set_rcvar() function has been removed from /etc/rc.subr. All 1166 base and ports rc.d scripts have been updated, so if you have a 1167 port installed with a script in /usr/local/etc/rc.d you can either 1168 hand-edit the rcvar= line, or reinstall the port. 1169 1170 An easy way to handle the mass-update of /etc/rc.d: 1171 rm /etc/rc.d/* && mergemaster -i 1172 117320120109: 1174 panic(9) now stops other CPUs in the SMP systems, disables interrupts 1175 on the current CPU and prevents other threads from running. 1176 This behavior can be reverted using the kern.stop_scheduler_on_panic 1177 tunable/sysctl. 1178 The new behavior can be incompatible with kern.sync_on_panic. 1179 118020111215: 1181 The carp(4) facility has been changed significantly. Configuration 1182 of the CARP protocol via ifconfig(8) has changed, as well as format 1183 of CARP events submitted to devd(8) has changed. See manual pages 1184 for more information. The arpbalance feature of carp(4) is currently 1185 not supported anymore. 1186 1187 Size of struct in_aliasreq, struct in6_aliasreq has changed. User 1188 utilities using SIOCAIFADDR, SIOCAIFADDR_IN6, e.g. ifconfig(8), 1189 need to be recompiled. 1190 119120111122: 1192 The acpi_wmi(4) status device /dev/wmistat has been renamed to 1193 /dev/wmistat0. 1194 119520111108: 1196 The option VFS_ALLOW_NONMPSAFE option has been added in order to 1197 explicitely support non-MPSAFE filesystems. 1198 It is on by default for all supported platform at this present 1199 time. 1200 120120111101: 1202 The broken amd(4) driver has been replaced with esp(4) in the amd64, 1203 i386 and pc98 GENERIC kernel configuration files. 1204 120520110930: 1206 sysinstall has been removed 1207 120820110923: 1209 The stable/9 branch created in subversion. This corresponds to the 1210 RELENG_9 branch in CVS. 1211 1212COMMON ITEMS: 1213 1214 General Notes 1215 ------------- 1216 Avoid using make -j when upgrading. While generally safe, there are 1217 sometimes problems using -j to upgrade. If your upgrade fails with 1218 -j, please try again without -j. From time to time in the past there 1219 have been problems using -j with buildworld and/or installworld. This 1220 is especially true when upgrading between "distant" versions (eg one 1221 that cross a major release boundary or several minor releases, or when 1222 several months have passed on the -current branch). 1223 1224 Sometimes, obscure build problems are the result of environment 1225 poisoning. This can happen because the make utility reads its 1226 environment when searching for values for global variables. To run 1227 your build attempts in an "environmental clean room", prefix all make 1228 commands with 'env -i '. See the env(1) manual page for more details. 1229 1230 When upgrading from one major version to another it is generally best 1231 to upgrade to the latest code in the currently installed branch first, 1232 then do an upgrade to the new branch. This is the best-tested upgrade 1233 path, and has the highest probability of being successful. Please try 1234 this approach before reporting problems with a major version upgrade. 1235 1236 When upgrading a live system, having a root shell around before 1237 installing anything can help undo problems. Not having a root shell 1238 around can lead to problems if pam has changed too much from your 1239 starting point to allow continued authentication after the upgrade. 1240 1241 This file should be read as a log of events. When a later event changes 1242 information of a prior event, the prior event should not be deleted. 1243 Instead, a pointer to the entry with the new information should be 1244 placed in the old entry. Readers of this file should also sanity check 1245 older entries before relying on them blindly. Authors of new entries 1246 should write them with this in mind. 1247 1248 ZFS notes 1249 --------- 1250 When upgrading the boot ZFS pool to a new version, always follow 1251 these two steps: 1252 1253 1.) recompile and reinstall the ZFS boot loader and boot block 1254 (this is part of "make buildworld" and "make installworld") 1255 1256 2.) update the ZFS boot block on your boot drive 1257 1258 The following example updates the ZFS boot block on the first 1259 partition (freebsd-boot) of a GPT partitioned drive ada0: 1260 "gpart bootcode -p /boot/gptzfsboot -i 1 ada0" 1261 1262 Non-boot pools do not need these updates. 1263 1264 To build a kernel 1265 ----------------- 1266 If you are updating from a prior version of FreeBSD (even one just 1267 a few days old), you should follow this procedure. It is the most 1268 failsafe as it uses a /usr/obj tree with a fresh mini-buildworld, 1269 1270 make kernel-toolchain 1271 make -DALWAYS_CHECK_MAKE buildkernel KERNCONF=YOUR_KERNEL_HERE 1272 make -DALWAYS_CHECK_MAKE installkernel KERNCONF=YOUR_KERNEL_HERE 1273 1274 To test a kernel once 1275 --------------------- 1276 If you just want to boot a kernel once (because you are not sure 1277 if it works, or if you want to boot a known bad kernel to provide 1278 debugging information) run 1279 make installkernel KERNCONF=YOUR_KERNEL_HERE KODIR=/boot/testkernel 1280 nextboot -k testkernel 1281 1282 To just build a kernel when you know that it won't mess you up 1283 -------------------------------------------------------------- 1284 This assumes you are already running a CURRENT system. Replace 1285 ${arch} with the architecture of your machine (e.g. "i386", 1286 "arm", "amd64", "ia64", "pc98", "sparc64", "powerpc", "mips", etc). 1287 1288 cd src/sys/${arch}/conf 1289 config KERNEL_NAME_HERE 1290 cd ../compile/KERNEL_NAME_HERE 1291 make depend 1292 make 1293 make install 1294 1295 If this fails, go to the "To build a kernel" section. 1296 1297 To rebuild everything and install it on the current system. 1298 ----------------------------------------------------------- 1299 # Note: sometimes if you are running current you gotta do more than 1300 # is listed here if you are upgrading from a really old current. 1301 1302 <make sure you have good level 0 dumps> 1303 make buildworld 1304 make kernel KERNCONF=YOUR_KERNEL_HERE 1305 [1] 1306 <reboot in single user> [3] 1307 mergemaster -Fp [5] 1308 make installworld 1309 mergemaster -Fi [4] 1310 make delete-old [6] 1311 <reboot> 1312 1313 To cross-install current onto a separate partition 1314 -------------------------------------------------- 1315 # In this approach we use a separate partition to hold 1316 # current's root, 'usr', and 'var' directories. A partition 1317 # holding "/", "/usr" and "/var" should be about 2GB in 1318 # size. 1319 1320 <make sure you have good level 0 dumps> 1321 <boot into -stable> 1322 make buildworld 1323 make buildkernel KERNCONF=YOUR_KERNEL_HERE 1324 <maybe newfs current's root partition> 1325 <mount current's root partition on directory ${CURRENT_ROOT}> 1326 make installworld DESTDIR=${CURRENT_ROOT} -DDB_FROM_SRC 1327 make distribution DESTDIR=${CURRENT_ROOT} # if newfs'd 1328 make installkernel KERNCONF=YOUR_KERNEL_HERE DESTDIR=${CURRENT_ROOT} 1329 cp /etc/fstab ${CURRENT_ROOT}/etc/fstab # if newfs'd 1330 <edit ${CURRENT_ROOT}/etc/fstab to mount "/" from the correct partition> 1331 <reboot into current> 1332 <do a "native" rebuild/install as described in the previous section> 1333 <maybe install compatibility libraries from ports/misc/compat*> 1334 <reboot> 1335 1336 1337 To upgrade in-place from stable to current 1338 ---------------------------------------------- 1339 <make sure you have good level 0 dumps> 1340 make buildworld [9] 1341 make kernel KERNCONF=YOUR_KERNEL_HERE [8] 1342 [1] 1343 <reboot in single user> [3] 1344 mergemaster -Fp [5] 1345 make installworld 1346 mergemaster -Fi [4] 1347 make delete-old [6] 1348 <reboot> 1349 1350 Make sure that you've read the UPDATING file to understand the 1351 tweaks to various things you need. At this point in the life 1352 cycle of current, things change often and you are on your own 1353 to cope. The defaults can also change, so please read ALL of 1354 the UPDATING entries. 1355 1356 Also, if you are tracking -current, you must be subscribed to 1357 freebsd-current@freebsd.org. Make sure that before you update 1358 your sources that you have read and understood all the recent 1359 messages there. If in doubt, please track -stable which has 1360 much fewer pitfalls. 1361 1362 [1] If you have third party modules, such as vmware, you 1363 should disable them at this point so they don't crash your 1364 system on reboot. 1365 1366 [3] From the bootblocks, boot -s, and then do 1367 fsck -p 1368 mount -u / 1369 mount -a 1370 cd src 1371 adjkerntz -i # if CMOS is wall time 1372 Also, when doing a major release upgrade, it is required that 1373 you boot into single user mode to do the installworld. 1374 1375 [4] Note: This step is non-optional. Failure to do this step 1376 can result in a significant reduction in the functionality of the 1377 system. Attempting to do it by hand is not recommended and those 1378 that pursue this avenue should read this file carefully, as well 1379 as the archives of freebsd-current and freebsd-hackers mailing lists 1380 for potential gotchas. The -U option is also useful to consider. 1381 See mergemaster(8) for more information. 1382 1383 [5] Usually this step is a noop. However, from time to time 1384 you may need to do this if you get unknown user in the following 1385 step. It never hurts to do it all the time. You may need to 1386 install a new mergemaster (cd src/usr.sbin/mergemaster && make 1387 install) after the buildworld before this step if you last updated 1388 from current before 20130425 or from -stable before 20130430. 1389 1390 [6] This only deletes old files and directories. Old libraries 1391 can be deleted by "make delete-old-libs", but you have to make 1392 sure that no program is using those libraries anymore. 1393 1394 [8] In order to have a kernel that can run the 4.x binaries needed to 1395 do an installworld, you must include the COMPAT_FREEBSD4 option in 1396 your kernel. Failure to do so may leave you with a system that is 1397 hard to boot to recover. A similar kernel option COMPAT_FREEBSD5 is 1398 required to run the 5.x binaries on more recent kernels. And so on 1399 for COMPAT_FREEBSD6 and COMPAT_FREEBSD7. 1400 1401 Make sure that you merge any new devices from GENERIC since the 1402 last time you updated your kernel config file. 1403 1404 [9] When checking out sources, you must include the -P flag to have 1405 cvs prune empty directories. 1406 1407 If CPUTYPE is defined in your /etc/make.conf, make sure to use the 1408 "?=" instead of the "=" assignment operator, so that buildworld can 1409 override the CPUTYPE if it needs to. 1410 1411 MAKEOBJDIRPREFIX must be defined in an environment variable, and 1412 not on the command line, or in /etc/make.conf. buildworld will 1413 warn if it is improperly defined. 1414FORMAT: 1415 1416This file contains a list, in reverse chronological order, of major 1417breakages in tracking -current. It is not guaranteed to be a complete 1418list of such breakages, and only contains entries since September 23, 2011. 1419If you need to see UPDATING entries from before that date, you will need 1420to fetch an UPDATING file from an older FreeBSD release. 1421 1422Copyright information: 1423 1424Copyright 1998-2009 M.
