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 1920170414: 20 Binds and sends to the loopback addresses, IPv6 and IPv4, will now 21 use any explicitly assigned loopback address available in the jail 22 instead of using the first assigned address of the jail. 23 2420170413: 25 As of r316810 for ipfilter, keep frags is no longer assumed when 26 keep state is specified in a rule. r316810 aligns ipfilter with 27 documentation in man pages separating keep frags from keep state. 28 This allows keep state to specified without forcing keep frags 29 and allows keep frags to be specified independently of keep state. 30 To maintain previous behaviour, also specify keep frags with 31 keep state (as documented in ipf.conf.5). 32 3320170402: 34 Clang, llvm, lldb, compiler-rt and libc++ have been upgraded to 4.0.0. 35 Please see the 20141231 entry below for information about prerequisites 36 and upgrading, if you are not already using clang 3.5.0 or higher. 37 3820170323: 39 The code that provides support for ZFS .zfs/ directory functionality 40 has been reimplemented. It's not possible now to create a snapshot 41 by mkdir under .zfs/snapshot/. That should be the only user visible 42 change. 43 4420170319: 45 Many changes in the IPsec code have been merged from the FreeBSD-CURRENT 46 branch. The IPSEC_FILTERTUNNEL kernel option is removed in favour of 47 corresponding sysctl. The IPSEC_NAT_T kernel option is also removed, 48 and now NAT-T is supported by default. Security associations now use 49 the single namespace for SPI allocation, so if you use several manually 50 configured security associations with the same SPI, this configuration 51 needs modification. 52 5320161217: 54 Clang, llvm, lldb, compiler-rt and libc++ have been upgraded to 3.9.1. 55 Please see the 20141231 entry below for information about prerequisites 56 and upgrading, if you are not already using clang 3.5.0 or higher. 57 5820161124: 59 Clang, llvm, lldb, compiler-rt and libc++ have been upgraded to 3.9.0. 60 Please see the 20141231 entry below for information about prerequisites 61 and upgrading, if you are not already using clang 3.5.0 or higher. 62 6320161119: 64 The layout of the pmap structure has changed for powerpc to put the pmap 65 statistics at the front for all CPU variations. libkvm(3) and all tools 66 that link against it need to be recompiled. 67 6820161030: 69 isl(4) and cyapa(4) drivers now require a new driver, 70 chromebook_platform(4), to work properly on Chromebook-class hardware. 71 On other types of hardware the drivers may need to be configured using 72 device hints. Please see the corresponding manual pages for details. 73 7420161210: 75 Relocatable object files with the extension of .So have been renamed 76 to use an extension of .pico instead. The purpose of this change is 77 to avoid a name clash with shared libraries on case-insensitive file 78 systems. On those file systems, foo.So is the same file as foo.so. 79 8020160622: 81 The libc stub for the pipe(2) system call has been replaced with 82 a wrapper that calls the pipe2(2) system call and the pipe(2) 83 system call is now only implemented by the kernels that include 84 "options COMPAT_FREEBSD10" in their config file (this is the 85 default). Users should ensure that this option is enabled in 86 their kernel or upgrade userspace to r302092 before upgrading their 87 kernel. 88 8920160527: 90 CAM will now strip leading spaces from SCSI disks' serial numbers. 91 This will effect users who create UFS filesystems on SCSI disks using 92 those disk's diskid device nodes. For example, if /etc/fstab 93 previously contained a line like 94 "/dev/diskid/DISK-%20%20%20%20%20%20%20ABCDEFG0123456", you should 95 change it to "/dev/diskid/DISK-ABCDEFG0123456". Users of geom 96 transforms like gmirror may also be affected. ZFS users should 97 generally be fine. 98 9920160523: 100 The bitstring(3) API has been updated with new functionality and 101 improved performance. But it is binary-incompatible with the old API. 102 Objects built with the new headers may not be linked against objects 103 built with the old headers. 104 10520160520: 106 The brk and sbrk functions have been removed from libc on arm64. 107 Binutils from ports has been updated to not link to these 108 functions and should be updated to the latest version before 109 installing a new libc. 110 11120160517: 112 The armv6 port now defaults to hard float ABI. Limited support 113 for running both hardfloat and soft float on the same system 114 is available using the libraries installed with -DWITH_LIBSOFT. 115 This has only been tested as an upgrade path for installworld 116 and packages may fail or need manual intervention to run. New 117 packages will be needed. 118 119 To update an existing self-hosted armv6hf system, you must add 120 TARGET_ARCH=armv6 on the make command line for both the build 121 and the install steps. 122 12320160510: 124 Kernel modules compiled outside of a kernel build now default to 125 installing to /boot/modules instead of /boot/kernel. Many kernel 126 modules built this way (such as those in ports) already overrode 127 KMODDIR explicitly to install into /boot/modules. However, 128 manually building and installing a module from /sys/modules will 129 now install to /boot/modules instead of /boot/kernel. 130 13120160414: 132 The CAM I/O scheduler has been committed to the kernel. There should be 133 no user visible impact. This does enable NCQ Trim on ada SSDs. While the 134 list of known rogues that claim support for this but actually corrupt 135 data is believed to be complete, be on the lookout for data 136 corruption. The known rogue list is believed to be complete: 137 138 o Crucial MX100, M550 drives with MU01 firmware. 139 o Micron M510 and M550 drives with MU01 firmware. 140 o Micron M500 prior to MU07 firmware 141 o Samsung 830, 840, and 850 all firmwares 142 o FCCT M500 all firmwares 143 144 Crucial has firmware http://www.crucial.com/usa/en/support-ssd-firmware 145 with working NCQ TRIM. For Micron branded drives, see your sales rep for 146 updated firmware. Black listed drives will work correctly because these 147 drives work correctly so long as no NCQ TRIMs are sent to them. Given 148 this list is the same as found in Linux, it's believed there are no 149 other rogues in the market place. All other models from the above 150 vendors work. 151 152 To be safe, if you are at all concerned, you can quirk each of your 153 drives to prevent NCQ from being sent by setting: 154 kern.cam.ada.X.quirks="0x2" 155 in loader.conf. If the drive requires the 4k sector quirk, set the 156 quirks entry to 0x3. 157 15820160330: 159 The FAST_DEPEND build option has been removed and its functionality is 160 now the one true way. The old mkdep(1) style of 'make depend' has 161 been removed. See 20160311 for further details. 162 16320160317: 164 Resource range types have grown from unsigned long to uintmax_t. All 165 drivers, and anything using libdevinfo, need to be recompiled. 166 16720160311: 168 WITH_FAST_DEPEND is now enabled by default for in-tree and out-of-tree 169 builds. It no longer runs mkdep(1) during 'make depend', and the 170 'make depend' stage can safely be skipped now as it is auto ran 171 when building 'make all' and will generate all SRCS and DPSRCS before 172 building anything else. Dependencies are gathered at compile time with 173 -MF flags kept in separate .depend files per object file. Users should 174 run 'make cleandepend' once if using -DNO_CLEAN to clean out older 175 stale .depend files. 176 17720160306: 178 On amd64, clang 3.8.0 can now insert sections of type AMD64_UNWIND into 179 kernel modules. Therefore, if you load any kernel modules at boot time, 180 please install the boot loaders after you install the kernel, but before 181 rebooting, e.g.: 182 183 make buildworld 184 make kernel KERNCONF=YOUR_KERNEL_HERE 185 make -C sys/boot install 186 <reboot in single user> 187 188 Then follow the usual steps, described in the General Notes section, 189 below. 190 19120160305: 192 Clang, llvm, lldb and compiler-rt have been upgraded to 3.8.0. Please 193 see the 20141231 entry below for information about prerequisites and 194 upgrading, if you are not already using clang 3.5.0 or higher. 195 19620160301: 197 The AIO subsystem is now a standard part of the kernel. The 198 VFS_AIO kernel option and aio.ko kernel module have been removed. 199 Due to stability concerns, asynchronous I/O requests are only 200 permitted on sockets and raw disks by default. To enable 201 asynchronous I/O requests on all file types, set the 202 vfs.aio.enable_unsafe sysctl to a non-zero value. 203 20420160226: 205 The ELF object manipulation tool objcopy is now provided by the 206 ELF Tool Chain project rather than by GNU binutils. It should be a 207 drop-in replacement, with the addition of arm64 support. The 208 (temporary) src.conf knob WITHOUT_ELFCOPY_AS_OBJCOPY knob may be set 209 to obtain the GNU version if necessary. 210 21120160129: 212 Building ZFS pools on top of zvols is prohibited by default. That 213 feature has never worked safely; it's always been prone to deadlocks. 214 Using a zvol as the backing store for a VM guest's virtual disk will 215 still work, even if the guest is using ZFS. Legacy behavior can be 216 restored by setting vfs.zfs.vol.recursive=1. 217 21820160119: 219 The NONE and HPN patches has been removed from OpenSSH. They are 220 still available in the security/openssh-portable port. 221 22220160113: 223 With the addition of ypldap(8), a new _ypldap user is now required 224 during installworld. "mergemaster -p" can be used to add the user 225 prior to installworld, as documented in the handbook. 226 22720151216: 228 The tftp loader (pxeboot) now uses the option root-path directive. As a 229 consequence it no longer looks for a pxeboot.4th file on the tftp 230 server. Instead it uses the regular /boot infrastructure as with the 231 other loaders. 232 23320151211: 234 The code to start recording plug and play data into the modules has 235 been committed. While the old tools will properly build a new kernel, 236 a number of warnings about "unknown metadata record 4" will be produced 237 for an older kldxref. To avoid such warnings, make sure to rebuild 238 the kernel toolchain (or world). Make sure that you have r292078 or 239 later when trying to build 292077 or later before rebuilding. 240 24120151207: 242 Debug data files are now built by default with 'make buildworld' and 243 installed with 'make installworld'. This facilitates debugging but 244 requires more disk space both during the build and for the installed 245 world. Debug files may be disabled by setting WITHOUT_DEBUG_FILES=yes 246 in src.conf(5). 247 24820151130: 249 r291527 changed the internal interface between the nfsd.ko and 250 nfscommon.ko modules. As such, they must both be upgraded to-gether. 251 __FreeBSD_version has been bumped because of this. 252 25320151108: 254 Add support for unicode collation strings leads to a change of 255 order of files listed by ls(1) for example. To get back to the old 256 behaviour, set LC_COLLATE environment variable to "C". 257 258 Databases administrators will need to reindex their databases given 259 collation results will be different. 260 261 Due to a bug in install(1) it is recommended to remove the ancient 262 locales before running make installworld. 263 264 rm -rf /usr/share/locale/* 265 26620151030: 267 The OpenSSL has been upgraded to 1.0.2d. Any binaries requiring 268 libcrypto.so.7 or libssl.so.7 must be recompiled. 269 27020151020: 271 Qlogic 24xx/25xx firmware images were updated from 5.5.0 to 7.3.0. 272 Kernel modules isp_2400_multi and isp_2500_multi were removed and 273 should be replaced with isp_2400 and isp_2500 modules respectively. 274 27520151017: 276 The build previously allowed using 'make -n' to not recurse into 277 sub-directories while showing what commands would be executed, and 278 'make -n -n' to recursively show commands. Now 'make -n' will recurse 279 and 'make -N' will not. 280 28120151012: 282 If you specify SENDMAIL_MC or SENDMAIL_CF in make.conf, mergemaster 283 and etcupdate will now use this file. A custom sendmail.cf is now 284 updated via this mechanism rather than via installworld. If you had 285 excluded sendmail.cf in mergemaster.rc or etcupdate.conf, you may 286 want to remove the exclusion or change it to "always install". 287 /etc/mail/sendmail.cf is now managed the same way regardless of 288 whether SENDMAIL_MC/SENDMAIL_CF is used. If you are not using 289 SENDMAIL_MC/SENDMAIL_CF there should be no change in behavior. 290 29120151011: 292 Compatibility shims for legacy ATA device names have been removed. 293 It includes ATA_STATIC_ID kernel option, kern.cam.ada.legacy_aliases 294 and kern.geom.raid.legacy_aliases loader tunables, kern.devalias.* 295 environment variables, /dev/ad* and /dev/ar* symbolic links. 296 29720151006: 298 Clang, llvm, lldb, compiler-rt and libc++ have been upgraded to 3.7.0. 299 Please see the 20141231 entry below for information about prerequisites 300 and upgrading, if you are not already using clang 3.5.0 or higher. 301 30220150924: 303 Kernel debug files have been moved to /usr/lib/debug/boot/kernel/, 304 and renamed from .symbols to .debug. This reduces the size requirements 305 on the boot partition or file system and provides consistency with 306 userland debug files. 307 308 When using the supported kernel installation method the 309 /usr/lib/debug/boot/kernel directory will be renamed (to kernel.old) 310 as is done with /boot/kernel. 311 312 Developers wishing to maintain the historical behavior of installing 313 debug files in /boot/kernel/ can set KERN_DEBUGDIR="" in src.conf(5). 314 31520150827: 316 The wireless drivers had undergone changes that remove the 'parent 317 interface' from the ifconfig -l output. The rc.d network scripts 318 used to check presence of a parent interface in the list, so old 319 scripts would fail to start wireless networking. Thus, etcupdate(3) 320 or mergemaster(8) run is required after kernel update, to update your 321 rc.d scripts in /etc. 322 32320150827: 324 pf no longer supports 'scrub fragment crop' or 'scrub fragment drop-ovl' 325 These configurations are now automatically interpreted as 326 'scrub fragment reassemble'. 327 32820150817: 329 Kernel-loadable modules for the random(4) device are back. To use 330 them, the kernel must have 331 332 device random 333 options RANDOM_LOADABLE 334 335 kldload(8) can then be used to load random_fortuna.ko 336 or random_yarrow.ko. Please note that due to the indirect 337 function calls that the loadable modules need to provide, 338 the build-in variants will be slightly more efficient. 339 340 The random(4) kernel option RANDOM_DUMMY has been retired due to 341 unpopularity. It was not all that useful anyway. 342 34320150813: 344 The WITHOUT_ELFTOOLCHAIN_TOOLS src.conf(5) knob has been retired. 345 Control over building the ELF Tool Chain tools is now provided by 346 the WITHOUT_TOOLCHAIN knob. 347 34820150810: 349 The polarity of Pulse Per Second (PPS) capture events with the 350 uart(4) driver has been corrected. Prior to this change the PPS 351 "assert" event corresponded to the trailing edge of a positive PPS 352 pulse and the "clear" event was the leading edge of the next pulse. 353 354 As the width of a PPS pulse in a typical GPS receiver is on the 355 order of 1 millisecond, most users will not notice any significant 356 difference with this change. 357 358 Anyone who has compensated for the historical polarity reversal by 359 configuring a negative offset equal to the pulse width will need to 360 remove that workaround. 361 36220150809: 363 The default group assigned to /dev/dri entries has been changed 364 from 'wheel' to 'video' with the id of '44'. If you want to have 365 access to the dri devices please add yourself to the video group 366 with: 367 368 # pw groupmod video -m $USER 369 37020150806: 371 The menu.rc and loader.rc files will now be replaced during 372 upgrades. Please migrate local changes to menu.rc.local and 373 loader.rc.local instead. 374 37520150805: 376 GNU Binutils versions of addr2line, c++filt, nm, readelf, size, 377 strings and strip have been removed. The src.conf(5) knob 378 WITHOUT_ELFTOOLCHAIN_TOOLS no longer provides the binutils tools. 379 38020150728: 381 As ZFS requires more kernel stack pages than is the default on some 382 architectures e.g. i386, it now warns if KSTACK_PAGES is less than 383 ZFS_MIN_KSTACK_PAGES (which is 4 at the time of writing). 384 385 Please consider using 'options KSTACK_PAGES=X' where X is greater 386 than or equal to ZFS_MIN_KSTACK_PAGES i.e. 4 in such configurations. 387 38820150706: 389 sendmail has been updated to 8.15.2. Starting with FreeBSD 11.0 390 and sendmail 8.15, sendmail uses uncompressed IPv6 addresses by 391 default, i.e., they will not contain "::". For example, instead 392 of ::1, it will be 0:0:0:0:0:0:0:1. This permits a zero subnet 393 to have a more specific match, such as different map entries for 394 IPv6:0:0 vs IPv6:0. This change requires that configuration 395 data (including maps, files, classes, custom ruleset, etc.) must 396 use the same format, so make certain such configuration data is 397 upgrading. As a very simple check search for patterns like 398 'IPv6:[0-9a-fA-F:]*::' and 'IPv6::'. To return to the old 399 behavior, set the m4 option confUSE_COMPRESSED_IPV6_ADDRESSES or 400 the cf option UseCompressedIPv6Addresses. 401 40220150630: 403 The default kernel entropy-processing algorithm is now 404 Fortuna, replacing Yarrow. 405 406 Assuming you have 'device random' in your kernel config 407 file, the configurations allow a kernel option to override 408 this default. You may choose *ONE* of: 409 410 options RANDOM_YARROW # Legacy /dev/random algorithm. 411 options RANDOM_DUMMY # Blocking-only driver. 412 413 If you have neither, you get Fortuna. For most people, 414 read no further, Fortuna will give a /dev/random that works 415 like it always used to, and the difference will be irrelevant. 416 417 If you remove 'device random', you get *NO* kernel-processed 418 entropy at all. This may be acceptable to folks building 419 embedded systems, but has complications. Carry on reading, 420 and it is assumed you know what you need. 421 422 *PLEASE* read random(4) and random(9) if you are in the 423 habit of tweaking kernel configs, and/or if you are a member 424 of the embedded community, wanting specific and not-usual 425 behaviour from your security subsystems. 426 427 NOTE!! If you use RANDOM_DUMMY and/or have no 'device 428 random', you will NOT have a functioning /dev/random, and 429 many cryptographic features will not work, including SSH. 430 You may also find strange behaviour from the random(3) set 431 of library functions, in particular sranddev(3), srandomdev(3) 432 and arc4random(3). The reason for this is that the KERN_ARND 433 sysctl only returns entropy if it thinks it has some to 434 share, and with RANDOM_DUMMY or no 'device random' this 435 will never happen. 436 43720150623: 438 An additional fix for the issue described in the 20150614 sendmail 439 entry below has been been committed in revision 284717. 440 44120150616: 442 FreeBSD's old make (fmake) has been removed from the system. It is 443 available as the devel/fmake port or via pkg install fmake. 444 44520150615: 446 The fix for the issue described in the 20150614 sendmail entry 447 below has been been committed in revision 284436. The work 448 around described in that entry is no longer needed unless the 449 default setting is overridden by a confDH_PARAMETERS configuration 450 setting of '5' or pointing to a 512 bit DH parameter file. 451 45220150614: 453 ALLOW_DEPRECATED_ATF_TOOLS/ATFFILE support has been removed from 454 atf.test.mk (included from bsd.test.mk). Please upgrade devel/atf 455 and devel/kyua to version 0.20+ and adjust any calling code to work 456 with Kyuafile and kyua. 457 45820150614: 459 The import of openssl to address the FreeBSD-SA-15:10.openssl 460 security advisory includes a change which rejects handshakes 461 with DH parameters below 768 bits. sendmail releases prior 462 to 8.15.2 (not yet released), defaulted to a 512 bit 463 DH parameter setting for client connections. To work around 464 this interoperability, sendmail can be configured to use a 465 2048 bit DH parameter by: 466 467 1. Edit /etc/mail/`hostname`.mc 468 2. If a setting for confDH_PARAMETERS does not exist or 469 exists and is set to a string beginning with '5', 470 replace it with '2'. 471 3. If a setting for confDH_PARAMETERS exists and is set to 472 a file path, create a new file with: 473 openssl dhparam -out /path/to/file 2048 474 4. Rebuild the .cf file: 475 cd /etc/mail/; make; make install 476 5. Restart sendmail: 477 cd /etc/mail/; make restart 478 479 A sendmail patch is coming, at which time this file will be 480 updated. 481 48220150604: 483 Generation of legacy formatted entries have been disabled by default 484 in pwd_mkdb(8), as all base system consumers of the legacy formatted 485 entries were converted to use the new format by default when the new, 486 machine independent format have been added and supported since FreeBSD 487 5.x. 488 489 Please see the pwd_mkdb(8) manual page for further details. 490 49120150525: 492 Clang and llvm have been upgraded to 3.6.1 release. Please see the 493 20141231 entry below for information about prerequisites and upgrading, 494 if you are not already using 3.5.0 or higher. 495 49620150521: 497 TI platform code switched to using vendor DTS files and this update 498 may break existing systems running on Beaglebone, Beaglebone Black, 499 and Pandaboard: 500 501 - dtb files should be regenerated/reinstalled. Filenames are the 502 same but content is different now 503 - GPIO addressing was changed, now each GPIO bank (32 pins per bank) 504 has its own /dev/gpiocX device, e.g. pin 121 on /dev/gpioc0 in old 505 addressing scheme is now pin 25 on /dev/gpioc3. 506 - Pandaboard: /etc/ttys should be updated, serial console device is 507 now /dev/ttyu2, not /dev/ttyu0 508 50920150501: 510 soelim(1) from gnu/usr.bin/groff has been replaced by usr.bin/soelim. 511 If you need the GNU extension from groff soelim(1), install groff 512 from package: pkg install groff, or via ports: textproc/groff. 513 51420150423: 515 chmod, chflags, chown and chgrp now affect symlinks in -R mode as 516 defined in symlink(7); previously symlinks were silently ignored. 517 51820150415: 519 The const qualifier has been removed from iconv(3) to comply with 520 POSIX. The ports tree is aware of this from r384038 onwards. 521 52220150416: 523 Libraries specified by LIBADD in Makefiles must have a corresponding 524 DPADD_<lib> variable to ensure correct dependencies. This is now 525 enforced in src.libnames.mk. 526 52720150324: 528 From legacy ata(4) driver was removed support for SATA controllers 529 supported by more functional drivers ahci(4), siis(4) and mvs(4). 530 Kernel modules ataahci and ataadaptec were removed completely, 531 replaced by ahci and mvs modules respectively. 532 53320150315: 534 Clang, llvm and lldb have been upgraded to 3.6.0 release. Please see 535 the 20141231 entry below for information about prerequisites and 536 upgrading, if you are not already using 3.5.0 or higher. 537 53820150307: 539 The 32-bit PowerPC kernel has been changed to a position-independent 540 executable. This can only be booted with a version of loader(8) 541 newer than January 31, 2015, so make sure to update both world and 542 kernel before rebooting. 543 54420150217: 545 If you are running a -CURRENT kernel since r273872 (Oct 30th, 2014), 546 but before r278950, the RNG was not seeded properly. Immediately 547 upgrade the kernel to r278950 or later and regenerate any keys (e.g. 548 ssh keys or openssl keys) that were generated w/ a kernel from that 549 range. This does not affect programs that directly used /dev/random 550 or /dev/urandom. All userland uses of arc4random(3) are affected. 551 55220150210: 553 The autofs(4) ABI was changed in order to restore binary compatibility 554 with 10.1-RELEASE. The automountd(8) daemon needs to be rebuilt to work 555 with the new kernel. 556 55720150131: 558 The powerpc64 kernel has been changed to a position-independent 559 executable. This can only be booted with a new version of loader(8), 560 so make sure to update both world and kernel before rebooting. 561 56220150118: 563 Clang and llvm have been upgraded to 3.5.1 release. This is a bugfix 564 only release, no new features have been added. Please see the 20141231 565 entry below for information about prerequisites and upgrading, if you 566 are not already using 3.5.0. 567 56820150107: 569 ELF tools addr2line, elfcopy (strip), nm, size, and strings are now 570 taken from the ELF Tool Chain project rather than GNU binutils. They 571 should be drop-in replacements, with the addition of arm64 support. 572 The WITHOUT_ELFTOOLCHAIN_TOOLS= knob may be used to obtain the 573 binutils tools, if necessary. See 20150805 for updated information. 574 57520150105: 576 The default Unbound configuration now enables remote control 577 using a local socket. Users who have already enabled the 578 local_unbound service should regenerate their configuration 579 by running "service local_unbound setup" as root. 580 58120150102: 582 The GNU texinfo and GNU info pages have been removed. 583 To be able to view GNU info pages please install texinfo from ports. 584 58520141231: 586 Clang, llvm and lldb have been upgraded to 3.5.0 release. 587 588 As of this release, a prerequisite for building clang, llvm and lldb is 589 a C++11 capable compiler and C++11 standard library. This means that to 590 be able to successfully build the cross-tools stage of buildworld, with 591 clang as the bootstrap compiler, your system compiler or cross compiler 592 should either be clang 3.3 or later, or gcc 4.8 or later, and your 593 system C++ library should be libc++, or libdstdc++ from gcc 4.8 or 594 later. 595 596 On any standard FreeBSD 10.x or 11.x installation, where clang and 597 libc++ are on by default (that is, on x86 or arm), this should work out 598 of the box. 599 600 On 9.x installations where clang is enabled by default, e.g. on x86 and 601 powerpc, libc++ will not be enabled by default, so libc++ should be 602 built (with clang) and installed first. If both clang and libc++ are 603 missing, build clang first, then use it to build libc++. 604 605 On 8.x and earlier installations, upgrade to 9.x first, and then follow 606 the instructions for 9.x above. 607 608 Sparc64 and mips users are unaffected, as they still use gcc 4.2.1 by 609 default, and do not build clang. 610 611 Many embedded systems are resource constrained, and will not be able to 612 build clang in a reasonable time, or in some cases at all. In those 613 cases, cross building bootable systems on amd64 is a workaround. 614 615 This new version of clang introduces a number of new warnings, of which 616 the following are most likely to appear: 617 618 -Wabsolute-value 619 620 This warns in two cases, for both C and C++: 621 * When the code is trying to take the absolute value of an unsigned 622 quantity, which is effectively a no-op, and almost never what was 623 intended. The code should be fixed, if at all possible. If you are 624 sure that the unsigned quantity can be safely cast to signed, without 625 loss of information or undefined behavior, you can add an explicit 626 cast, or disable the warning. 627 628 * When the code is trying to take an absolute value, but the called 629 abs() variant is for the wrong type, which can lead to truncation. 630 If you want to disable the warning instead of fixing the code, please 631 make sure that truncation will not occur, or it might lead to unwanted 632 side-effects. 633 634 -Wtautological-undefined-compare and 635 -Wundefined-bool-conversion 636 637 These warn when C++ code is trying to compare 'this' against NULL, while 638 'this' should never be NULL in well-defined C++ code. However, there is 639 some legacy (pre C++11) code out there, which actively abuses this 640 feature, which was less strictly defined in previous C++ versions. 641 642 Squid and openjdk do this, for example. The warning can be turned off 643 for C++98 and earlier, but compiling the code in C++11 mode might result 644 in unexpected behavior; for example, the parts of the program that are 645 unreachable could be optimized away. 646 64720141222: 648 The old NFS client and server (kernel options NFSCLIENT, NFSSERVER) 649 kernel sources have been removed. The .h files remain, since some 650 utilities include them. This will need to be fixed later. 651 If "mount -t oldnfs ..." is attempted, it will fail. 652 If the "-o" option on mountd(8), nfsd(8) or nfsstat(1) is used, 653 the utilities will report errors. 654 65520141121: 656 The handling of LOCAL_LIB_DIRS has been altered to skip addition of 657 directories to top level SUBDIR variable when their parent 658 directory is included in LOCAL_DIRS. Users with build systems with 659 such hierarchies and without SUBDIR entries in the parent 660 directory Makefiles should add them or add the directories to 661 LOCAL_DIRS. 662 66320141109: 664 faith(4) and faithd(8) have been removed from the base system. Faith 665 has been obsolete for a very long time. 666 66720141104: 668 vt(4), the new console driver, is enabled by default. It brings 669 support for Unicode and double-width characters, as well as 670 support for UEFI and integration with the KMS kernel video 671 drivers. 672 673 You may need to update your console settings in /etc/rc.conf, 674 most probably the keymap. During boot, /etc/rc.d/syscons will 675 indicate what you need to do. 676 677 vt(4) still has issues and lacks some features compared to 678 syscons(4). See the wiki for up-to-date information: 679 https://wiki.freebsd.org/Newcons 680 681 If you want to keep using syscons(4), you can do so by adding 682 the following line to /boot/loader.conf: 683 kern.vty=sc 684 68520141102: 686 pjdfstest has been integrated into kyua as an opt-in test suite. 687 Please see share/doc/pjdfstest/README for more details on how to 688 execute it. 689 69020141009: 691 gperf has been removed from the base system for architectures 692 that use clang. Ports that require gperf will obtain it from the 693 devel/gperf port. 694 69520140923: 696 pjdfstest has been moved from tools/regression/pjdfstest to 697 contrib/pjdfstest . 698 69920140922: 700 At svn r271982, The default linux compat kernel ABI has been adjusted 701 to 2.6.18 in support of the linux-c6 compat ports infrastructure 702 update. If you wish to continue using the linux-f10 compat ports, 703 add compat.linux.osrelease=2.6.16 to your local sysctl.conf. Users are 704 encouraged to update their linux-compat packages to linux-c6 during 705 their next update cycle. 706 70720140729: 708 The ofwfb driver, used to provide a graphics console on PowerPC when 709 using vt(4), no longer allows mmap() of all physical memory. This 710 will prevent Xorg on PowerPC with some ATI graphics cards from 711 initializing properly unless x11-servers/xorg-server is updated to 712 1.12.4_8 or newer. 713 71420140723: 715 The xdev targets have been converted to using TARGET and 716 TARGET_ARCH instead of XDEV and XDEV_ARCH. 717 71820140719: 719 The default unbound configuration has been modified to address 720 issues with reverse lookups on networks that use private 721 address ranges. If you use the local_unbound service, run 722 "service local_unbound setup" as root to regenerate your 723 configuration, then "service local_unbound reload" to load the 724 new configuration. 725 72620140709: 727 The GNU texinfo and GNU info pages are not built and installed 728 anymore, WITH_INFO knob has been added to allow to built and install 729 them again. 730 UPDATE: see 20150102 entry on texinfo's removal 731 73220140708: 733 The GNU readline library is now an INTERNALLIB - that is, it is 734 statically linked into consumers (GDB and variants) in the base 735 system, and the shared library is no longer installed. The 736 devel/readline port is available for third party software that 737 requires readline. 738 73920140702: 740 The Itanium architecture (ia64) has been removed from the list of 741 known architectures. This is the first step in the removal of the 742 architecture. 743 74420140701: 745 Commit r268115 has added NFSv4.1 server support, merged from 746 projects/nfsv4.1-server. Since this includes changes to the 747 internal interfaces between the NFS related modules, a full 748 build of the kernel and modules will be necessary. 749 __FreeBSD_version has been bumped. 750 75120140629: 752 The WITHOUT_VT_SUPPORT kernel config knob has been renamed 753 WITHOUT_VT. (The other _SUPPORT knobs have a consistent meaning 754 which differs from the behaviour controlled by this knob.) 755 75620140619: 757 Maximal length of the serial number in CTL was increased from 16 to 758 64 chars, that breaks ABI. All CTL-related tools, such as ctladm 759 and ctld, need to be rebuilt to work with a new kernel. 760 76120140606: 762 The libatf-c and libatf-c++ major versions were downgraded to 0 and 763 1 respectively to match the upstream numbers. They were out of 764 sync because, when they were originally added to FreeBSD, the 765 upstream versions were not respected. These libraries are private 766 and not yet built by default, so renumbering them should be a 767 non-issue. However, unclean source trees will yield broken test 768 programs once the operator executes "make delete-old-libs" after a 769 "make installworld". 770 771 Additionally, the atf-sh binary was made private by moving it into 772 /usr/libexec/. Already-built shell test programs will keep the 773 path to the old binary so they will break after "make delete-old" 774 is run. 775 776 If you are using WITH_TESTS=yes (not the default), wipe the object 777 tree and rebuild from scratch to prevent spurious test failures. 778 This is only needed once: the misnumbered libraries and misplaced 779 binaries have been added to OptionalObsoleteFiles.inc so they will 780 be removed during a clean upgrade. 781 78220140512: 783 Clang and llvm have been upgraded to 3.4.1 release. 784 78520140508: 786 We bogusly installed src.opts.mk in /usr/share/mk. This file should 787 be removed to avoid issues in the future (and has been added to 788 ObsoleteFiles.inc). 789 79020140505: 791 /etc/src.conf now affects only builds of the FreeBSD src tree. In the 792 past, it affected all builds that used the bsd.*.mk files. The old 793 behavior was a bug, but people may have relied upon it. To get this 794 behavior back, you can .include /etc/src.conf from /etc/make.conf 795 (which is still global and isn't changed). This also changes the 796 behavior of incremental builds inside the tree of individual 797 directories. Set MAKESYSPATH to ".../share/mk" to do that. 798 Although this has survived make universe and some upgrade scenarios, 799 other upgrade scenarios may have broken. At least one form of 800 temporary breakage was fixed with MAKESYSPATH settings for buildworld 801 as well... In cases where MAKESYSPATH isn't working with this 802 setting, you'll need to set it to the full path to your tree. 803 804 One side effect of all this cleaning up is that bsd.compiler.mk 805 is no longer implicitly included by bsd.own.mk. If you wish to 806 use COMPILER_TYPE, you must now explicitly include bsd.compiler.mk 807 as well. 808 80920140430: 810 The lindev device has been removed since /dev/full has been made a 811 standard device. __FreeBSD_version has been bumped. 812 81320140424: 814 The knob WITHOUT_VI was added to the base system, which controls 815 building ex(1), vi(1), etc. Older releases of FreeBSD required ex(1) 816 in order to reorder files share/termcap and didn't build ex(1) as a 817 build tool, so building/installing with WITH_VI is highly advised for 818 build hosts for older releases. 819 820 This issue has been fixed in stable/9 and stable/10 in r277022 and 821 r276991, respectively. 822 82320140418: 824 The YES_HESIOD knob has been removed. It has been obsolete for 825 a decade. Please move to using WITH_HESIOD instead or your builds 826 will silently lack HESIOD. 827 82820140405: 829 The uart(4) driver has been changed with respect to its handling 830 of the low-level console. Previously the uart(4) driver prevented 831 any process from changing the baudrate or the CLOCAL and HUPCL 832 control flags. By removing the restrictions, operators can make 833 changes to the serial console port without having to reboot. 834 However, when getty(8) is started on the serial device that is 835 associated with the low-level console, a misconfigured terminal 836 line in /etc/ttys will now have a real impact. 837 Before upgrading the kernel, make sure that /etc/ttys has the 838 serial console device configured as 3wire without baudrate to 839 preserve the previous behaviour. E.g: 840 ttyu0 "/usr/libexec/getty 3wire" vt100 on secure 841 84220140306: 843 Support for libwrap (TCP wrappers) in rpcbind was disabled by default 844 to improve performance. To re-enable it, if needed, run rpcbind 845 with command line option -W. 846 84720140226: 848 Switched back to the GPL dtc compiler due to updates in the upstream 849 dts files not being supported by the BSDL dtc compiler. You will need 850 to rebuild your kernel toolchain to pick up the new compiler. Core dumps 851 may result while building dtb files during a kernel build if you fail 852 to do so. Set WITHOUT_GPL_DTC if you require the BSDL compiler. 853 85420140216: 855 Clang and llvm have been upgraded to 3.4 release. 856 85720140216: 858 The nve(4) driver has been removed. Please use the nfe(4) driver 859 for NVIDIA nForce MCP Ethernet adapters instead. 860 86120140212: 862 An ABI incompatibility crept into the libc++ 3.4 import in r261283. 863 This could cause certain C++ applications using shared libraries built 864 against the previous version of libc++ to crash. The incompatibility 865 has now been fixed, but any C++ applications or shared libraries built 866 between r261283 and r261801 should be recompiled. 867 86820140204: 869 OpenSSH will now ignore errors caused by kernel lacking of Capsicum 870 capability mode support. Please note that enabling the feature in 871 kernel is still highly recommended. 872 87320140131: 874 OpenSSH is now built with sandbox support, and will use sandbox as 875 the default privilege separation method. This requires Capsicum 876 capability mode support in kernel. 877 87820140128: 879 The libelf and libdwarf libraries have been updated to newer 880 versions from upstream. Shared library version numbers for 881 these two libraries were bumped. Any ports or binaries 882 requiring these two libraries should be recompiled. 883 __FreeBSD_version is bumped to 1100006. 884 88520140110: 886 If a Makefile in a tests/ directory was auto-generating a Kyuafile 887 instead of providing an explicit one, this would prevent such 888 Makefile from providing its own Kyuafile in the future during 889 NO_CLEAN builds. This has been fixed in the Makefiles but manual 890 intervention is needed to clean an objdir if you use NO_CLEAN: 891 # find /usr/obj -name Kyuafile | xargs rm -f 892 89320131213: 894 The behavior of gss_pseudo_random() for the krb5 mechanism 895 has changed, for applications requesting a longer random string 896 than produced by the underlying enctype's pseudo-random() function. 897 In particular, the random string produced from a session key of 898 enctype aes256-cts-hmac-sha1-96 or aes256-cts-hmac-sha1-96 will 899 be different at the 17th octet and later, after this change. 900 The counter used in the PRF+ construction is now encoded as a 901 big-endian integer in accordance with RFC 4402. 902 __FreeBSD_version is bumped to 1100004. 903 90420131108: 905 The WITHOUT_ATF build knob has been removed and its functionality 906 has been subsumed into the more generic WITHOUT_TESTS. If you were 907 using the former to disable the build of the ATF libraries, you 908 should change your settings to use the latter. 909 91020131025: 911 The default version of mtree is nmtree which is obtained from 912 NetBSD. The output is generally the same, but may vary 913 slightly. If you found you need identical output adding 914 "-F freebsd9" to the command line should do the trick. For the 915 time being, the old mtree is available as fmtree. 916 91720131014: 918 libbsdyml has been renamed to libyaml and moved to /usr/lib/private. 919 This will break ports-mgmt/pkg. Rebuild the port, or upgrade to pkg 920 1.1.4_8 and verify bsdyml not linked in, before running "make 921 delete-old-libs": 922 # make -C /usr/ports/ports-mgmt/pkg build deinstall install clean 923 or 924 # pkg install pkg; ldd /usr/local/sbin/pkg | grep bsdyml 925 92620131010: 927 The stable/10 branch has been created in subversion from head 928 revision r256279. 929 93020131010: 931 The rc.d/jail script has been updated to support jail(8) 932 configuration file. The "jail_<jname>_*" rc.conf(5) variables 933 for per-jail configuration are automatically converted to 934 /var/run/jail.<jname>.conf before the jail(8) utility is invoked. 935 This is transparently backward compatible. See below about some 936 incompatibilities and rc.conf(5) manual page for more details. 937 938 These variables are now deprecated in favor of jail(8) configuration 939 file. One can use "rc.d/jail config <jname>" command to generate 940 a jail(8) configuration file in /var/run/jail.<jname>.conf without 941 running the jail(8) utility. The default pathname of the 942 configuration file is /etc/jail.conf and can be specified by 943 using $jail_conf or $jail_<jname>_conf variables. 944 945 Please note that jail_devfs_ruleset accepts an integer at 946 this moment. Please consider to rewrite the ruleset name 947 with an integer. 948 94920130930: 950 BIND has been removed from the base system. If all you need 951 is a local resolver, simply enable and start the local_unbound 952 service instead. Otherwise, several versions of BIND are 953 available in the ports tree. The dns/bind99 port is one example. 954 955 With this change, nslookup(1) and dig(1) are no longer in the base 956 system. Users should instead use host(1) and drill(1) which are 957 in the base system. Alternatively, nslookup and dig can 958 be obtained by installing the dns/bind-tools port. 959 96020130916: 961 With the addition of unbound(8), a new unbound user is now 962 required during installworld. "mergemaster -p" can be used to 963 add the user prior to installworld, as documented in the handbook. 964 96520130911: 966 OpenSSH is now built with DNSSEC support, and will by default 967 silently trust signed SSHFP records. This can be controlled with 968 the VerifyHostKeyDNS client configuration setting. DNSSEC support 969 can be disabled entirely with the WITHOUT_LDNS option in src.conf. 970 97120130906: 972 The GNU Compiler Collection and C++ standard library (libstdc++) 973 are no longer built by default on platforms where clang is the system 974 compiler. You can enable them with the WITH_GCC and WITH_GNUCXX 975 options in src.conf. 976 97720130905: 978 The PROCDESC kernel option is now part of the GENERIC kernel 979 configuration and is required for the rwhod(8) to work. 980 If you are using custom kernel configuration, you should include 981 'options PROCDESC'. 982 98320130905: 984 The API and ABI related to the Capsicum framework was modified 985 in backward incompatible way. The userland libraries and programs 986 have to be recompiled to work with the new kernel. This includes the 987 following libraries and programs, but the whole buildworld is 988 advised: libc, libprocstat, dhclient, tcpdump, hastd, hastctl, 989 kdump, procstat, rwho, rwhod, uniq. 990 99120130903: 992 AES-NI intrinsic support has been added to gcc. The AES-NI module 993 has been updated to use this support. A new gcc is required to build 994 the aesni module on both i386 and amd64. 995 99620130821: 997 The PADLOCK_RNG and RDRAND_RNG kernel options are now devices. 998 Thus "device padlock_rng" and "device rdrand_rng" should be 999 used instead of "options PADLOCK_RNG" & "options RDRAND_RNG". 1000 100120130813: 1002 WITH_ICONV has been split into two feature sets. WITH_ICONV now 1003 enables just the iconv* functionality and is now on by default. 1004 WITH_LIBICONV_COMPAT enables the libiconv api and link time 1005 compatibility. Set WITHOUT_ICONV to build the old way. 1006 If you have been using WITH_ICONV before, you will very likely 1007 need to turn on WITH_LIBICONV_COMPAT. 1008 100920130806: 1010 INVARIANTS option now enables DEBUG for code with OpenSolaris and 1011 Illumos origin, including ZFS. If you have INVARIANTS in your 1012 kernel configuration, then there is no need to set DEBUG or ZFS_DEBUG 1013 explicitly. 1014 DEBUG used to enable witness(9) tracking of OpenSolaris (mostly ZFS) 1015 locks if WITNESS option was set. Because that generated a lot of 1016 witness(9) reports and all of them were believed to be false 1017 positives, this is no longer done. New option OPENSOLARIS_WITNESS 1018 can be used to achieve the previous behavior. 1019 102020130806: 1021 Timer values in IPv6 data structures now use time_uptime instead 1022 of time_second. Although this is not a user-visible functional 1023 change, userland utilities which directly use them---ndp(8), 1024 rtadvd(8), and rtsold(8) in the base system---need to be updated 1025 to r253970 or later. 1026 102720130802: 1028 find -delete can now delete the pathnames given as arguments, 1029 instead of only files found below them or if the pathname did 1030 not contain any slashes. Formerly, the following error message 1031 would result: 1032 1033 find: -delete: <path>: relative path potentially not safe 1034 1035 Deleting the pathnames given as arguments can be prevented 1036 without error messages using -mindepth 1 or by changing 1037 directory and passing "." as argument to find. This works in the 1038 old as well as the new version of find. 1039 104020130726: 1041 Behavior of devfs rules path matching has been changed. 1042 Pattern is now always matched against fully qualified devfs 1043 path and slash characters must be explicitly matched by 1044 slashes in pattern (FNM_PATHNAME). Rulesets involving devfs 1045 subdirectories must be reviewed. 1046 104720130716: 1048 The default ARM ABI has changed to the ARM EABI. The old ABI is 1049 incompatible with the ARM EABI and all programs and modules will 1050 need to be rebuilt to work with a new kernel. 1051 1052 To keep using the old ABI ensure the WITHOUT_ARM_EABI knob is set. 1053 1054 NOTE: Support for the old ABI will be removed in the future and 1055 users are advised to upgrade. 1056 105720130709: 1058 pkg_install has been disconnected from the build if you really need it 1059 you should add WITH_PKGTOOLS in your src.conf(5). 1060 106120130709: 1062 Most of network statistics structures were changed to be able 1063 keep 64-bits counters. Thus all tools, that work with networking 1064 statistics, must be rebuilt (netstat(1), bsnmpd(1), etc.) 1065 106620130618: 1067 Fix a bug that allowed a tracing process (e.g. gdb) to write 1068 to a memory-mapped file in the traced process's address space 1069 even if neither the traced process nor the tracing process had 1070 write access to that file. 1071 107220130615: 1073 CVS has been removed from the base system. An exact copy 1074 of the code is available from the devel/cvs port. 1075 107620130613: 1077 Some people report the following error after the switch to bmake: 1078 1079 make: illegal option -- J 1080 usage: make [-BPSXeiknpqrstv] [-C directory] [-D variable] 1081 ... 1082 *** [buildworld] Error code 2 1083 1084 this likely due to an old instance of make in 1085 ${MAKEPATH} (${MAKEOBJDIRPREFIX}${.CURDIR}/make.${MACHINE}) 1086 which src/Makefile will use that blindly, if it exists, so if 1087 you see the above error: 1088 1089 rm -rf `make -V MAKEPATH` 1090 1091 should resolve it. 1092 109320130516: 1094 Use bmake by default. 1095 Whereas before one could choose to build with bmake via 1096 -DWITH_BMAKE one must now use -DWITHOUT_BMAKE to use the old 1097 make. The goal is to remove these knobs for 10-RELEASE. 1098 1099 It is worth noting that bmake (like gmake) treats the command 1100 line as the unit of failure, rather than statements within the 1101 command line. Thus '(cd some/where && dosomething)' is safer 1102 than 'cd some/where; dosomething'. The '()' allows consistent 1103 behavior in parallel build. 1104 110520130429: 1106 Fix a bug that allows NFS clients to issue READDIR on files. 1107 110820130426: 1109 The WITHOUT_IDEA option has been removed because 1110 the IDEA patent expired. 1111 111220130426: 1113 The sysctl which controls TRIM support under ZFS has been renamed 1114 from vfs.zfs.trim_disable -> vfs.zfs.trim.enabled and has been 1115 enabled by default. 1116 111720130425: 1118 The mergemaster command now uses the default MAKEOBJDIRPREFIX 1119 rather than creating it's own in the temporary directory in 1120 order allow access to bootstrapped versions of tools such as 1121 install and mtree. When upgrading from version of FreeBSD where 1122 the install command does not support -l, you will need to 1123 install a new mergemaster command if mergemaster -p is required. 1124 This can be accomplished with the command (cd src/usr.sbin/mergemaster 1125 && make install). 1126 112720130404: 1128 Legacy ATA stack, disabled and replaced by new CAM-based one since 1129 FreeBSD 9.0, completely removed from the sources. Kernel modules 1130 atadisk and atapi*, user-level tools atacontrol and burncd are 1131 removed. Kernel option `options ATA_CAM` is now permanently enabled 1132 and removed. 1133 113420130319: 1135 SOCK_CLOEXEC and SOCK_NONBLOCK flags have been added to socket(2) 1136 and socketpair(2). Software, in particular Kerberos, may 1137 automatically detect and use these during building. The resulting 1138 binaries will not work on older kernels. 1139 114020130308: 1141 CTL_DISABLE has also been added to the sparc64 GENERIC (for further 1142 information, see the respective 20130304 entry). 1143 114420130304: 1145 Recent commits to callout(9) changed the size of struct callout, 1146 so the KBI is probably heavily disturbed. Also, some functions 1147 in callout(9)/sleep(9)/sleepqueue(9)/condvar(9) KPIs were replaced 1148 by macros. Every kernel module using it won't load, so rebuild 1149 is requested. 1150 1151 The ctl device has been re-enabled in GENERIC for i386 and amd64, 1152 but does not initialize by default (because of the new CTL_DISABLE 1153 option) to save memory. To re-enable it, remove the CTL_DISABLE 1154 option from the kernel config file or set kern.cam.ctl.disable=0 1155 in /boot/loader.conf. 1156 115720130301: 1158 The ctl device has been disabled in GENERIC for i386 and amd64. 1159 This was done due to the extra memory being allocated at system 1160 initialisation time by the ctl driver which was only used if 1161 a CAM target device was created. This makes a FreeBSD system 1162 unusable on 128MB or less of RAM. 1163 116420130208: 1165 A new compression method (lz4) has been merged to -HEAD. Please 1166 refer to zpool-features(7) for more information. 1167 1168 Please refer to the "ZFS notes" section of this file for information 1169 on upgrading boot ZFS pools. 1170 117120130129: 1172 A BSD-licensed patch(1) variant has been added and is installed 1173 as bsdpatch, being the GNU version the default patch. 1174 To inverse the logic and use the BSD-licensed one as default, 1175 while having the GNU version installed as gnupatch, rebuild 1176 and install world with the WITH_BSD_PATCH knob set. 1177 117820130121: 1179 Due to the use of the new -l option to install(1) during build 1180 and install, you must take care not to directly set the INSTALL 1181 make variable in your /etc/make.conf, /etc/src.conf, or on the 1182 command line. If you wish to use the -C flag for all installs 1183 you may be able to add INSTALL+=-C to /etc/make.conf or 1184 /etc/src.conf. 1185 118620130118: 1187 The install(1) option -M has changed meaning and now takes an 1188 argument that is a file or path to append logs to. In the 1189 unlikely event that -M was the last option on the command line 1190 and the command line contained at least two files and a target 1191 directory the first file will have logs appended to it. The -M 1192 option served little practical purpose in the last decade so its 1193 use is expected to be extremely rare. 1194 119520121223: 1196 After switching to Clang as the default compiler some users of ZFS 1197 on i386 systems started to experience stack overflow kernel panics. 1198 Please consider using 'options KSTACK_PAGES=4' in such configurations. 1199 120020121222: 1201 GEOM_LABEL now mangles label names read from file system metadata. 1202 Mangling affect labels containing spaces, non-printable characters, 1203 '%' or '"'. Device names in /etc/fstab and other places may need to 1204 be updated. 1205 120620121217: 1207 By default, only the 10 most recent kernel dumps will be saved. To 1208 restore the previous behaviour (no limit on the number of kernel dumps 1209 stored in the dump directory) add the following line to /etc/rc.conf: 1210 1211 savecore_flags="" 1212 121320121201: 1214 With the addition of auditdistd(8), a new auditdistd user is now 1215 required during installworld. "mergemaster -p" can be used to 1216 add the user prior to installworld, as documented in the handbook. 1217 121820121117: 1219 The sin6_scope_id member variable in struct sockaddr_in6 is now 1220 filled by the kernel before passing the structure to the userland via 1221 sysctl or routing socket. This means the KAME-specific embedded scope 1222 id in sin6_addr.s6_addr[2] is always cleared in userland application. 1223 This behavior can be controlled by net.inet6.ip6.deembed_scopeid. 1224 __FreeBSD_version is bumped to 1000025. 1225 122620121105: 1227 On i386 and amd64 systems WITH_CLANG_IS_CC is now the default. 1228 This means that the world and kernel will be compiled with clang 1229 and that clang will be installed as /usr/bin/cc, /usr/bin/c++, 1230 and /usr/bin/cpp. To disable this behavior and revert to building 1231 with gcc, compile with WITHOUT_CLANG_IS_CC. Really old versions 1232 of current may need to bootstrap WITHOUT_CLANG first if the clang 1233 build fails (its compatibility window doesn't extend to the 9 stable 1234 branch point). 1235 123620121102: 1237 The IPFIREWALL_FORWARD kernel option has been removed. Its 1238 functionality now turned on by default. 1239 124020121023: 1241 The ZERO_COPY_SOCKET kernel option has been removed and 1242 split into SOCKET_SEND_COW and SOCKET_RECV_PFLIP. 1243 NB: SOCKET_SEND_COW uses the VM page based copy-on-write 1244 mechanism which is not safe and may result in kernel crashes. 1245 NB: The SOCKET_RECV_PFLIP mechanism is useless as no current 1246 driver supports disposeable external page sized mbuf storage. 1247 Proper replacements for both zero-copy mechanisms are under 1248 consideration and will eventually lead to complete removal 1249 of the two kernel options. 1250 125120121023: 1252 The IPv4 network stack has been converted to network byte 1253 order. The following modules need to be recompiled together 1254 with kernel: carp(4), divert(4), gif(4), siftr(4), gre(4), 1255 pf(4), ipfw(4), ng_ipfw(4), stf(4). 1256 125720121022: 1258 Support for non-MPSAFE filesystems was removed from VFS. The 1259 VFS_VERSION was bumped, all filesystem modules shall be 1260 recompiled. 1261 126220121018: 1263 All the non-MPSAFE filesystems have been disconnected from 1264 the build. The full list includes: codafs, hpfs, ntfs, nwfs, 1265 portalfs, smbfs, xfs. 1266 126720121016: 1268 The interface cloning API and ABI has changed. The following 1269 modules need to be recompiled together with kernel: 1270 ipfw(4), pfsync(4), pflog(4), usb(4), wlan(4), stf(4), 1271 vlan(4), disc(4), edsc(4), if_bridge(4), gif(4), tap(4), 1272 faith(4), epair(4), enc(4), tun(4), if_lagg(4), gre(4). 1273 127420121015: 1275 The sdhci driver was split in two parts: sdhci (generic SD Host 1276 Controller logic) and sdhci_pci (actual hardware driver). 1277 No kernel config modifications are required, but if you 1278 load sdhc as a module you must switch to sdhci_pci instead. 1279 128020121014: 1281 Import the FUSE kernel and userland support into base system. 1282 128320121013: 1284 The GNU sort(1) program has been removed since the BSD-licensed 1285 sort(1) has been the default for quite some time and no serious 1286 problems have been reported. The corresponding WITH_GNU_SORT 1287 knob has also gone. 1288 128920121006: 1290 The pfil(9) API/ABI for AF_INET family has been changed. Packet 1291 filtering modules: pf(4), ipfw(4), ipfilter(4) need to be recompiled 1292 with new kernel. 1293 129420121001: 1295 The net80211(4) ABI has been changed to allow for improved driver 1296 PS-POLL and power-save support. All wireless drivers need to be 1297 recompiled to work with the new kernel. 1298 129920120913: 1300 The random(4) support for the VIA hardware random number 1301 generator (`PADLOCK') is no longer enabled unconditionally. 1302 Add the padlock_rng device in the custom kernel config if 1303 needed. The GENERIC kernels on i386 and amd64 do include the 1304 device, so the change only affects the custom kernel 1305 configurations. 1306 130720120908: 1308 The pf(4) packet filter ABI has been changed. pfctl(8) and 1309 snmp_pf module need to be recompiled to work with new kernel. 1310 131120120828: 1312 A new ZFS feature flag "com.delphix:empty_bpobj" has been merged 1313 to -HEAD. Pools that have empty_bpobj in active state can not be 1314 imported read-write with ZFS implementations that do not support 1315 this feature. For more information read the zpool-features(5) 1316 manual page. 1317 131820120727: 1319 The sparc64 ZFS loader has been changed to no longer try to auto- 1320 detect ZFS providers based on diskN aliases but now requires these 1321 to be explicitly listed in the OFW boot-device environment variable. 1322 132320120712: 1324 The OpenSSL has been upgraded to 1.0.1c. Any binaries requiring 1325 libcrypto.so.6 or libssl.so.6 must be recompiled. Also, there are 1326 configuration changes. Make sure to merge /etc/ssl/openssl.cnf. 1327 132820120712: 1329 The following sysctls and tunables have been renamed for consistency 1330 with other variables: 1331 kern.cam.da.da_send_ordered -> kern.cam.da.send_ordered 1332 kern.cam.ada.ada_send_ordered -> kern.cam.ada.send_ordered 1333 133420120628: 1335 The sort utility has been replaced with BSD sort. For now, GNU sort 1336 is also available as "gnusort" or the default can be set back to 1337 GNU sort by setting WITH_GNU_SORT. In this case, BSD sort will be 1338 installed as "bsdsort". 1339 134020120611: 1341 A new version of ZFS (pool version 5000) has been merged to -HEAD. 1342 Starting with this version the old system of ZFS pool versioning 1343 is superseded by "feature flags". This concept enables forward 1344 compatibility against certain future changes in functionality of ZFS 1345 pools. The first read-only compatible "feature flag" for ZFS pools 1346 is named "com.delphix:async_destroy". For more information 1347 read the new zpool-features(5) manual page. 1348 Please refer to the "ZFS notes" section of this file for information 1349 on upgrading boot ZFS pools. 1350 135120120417: 1352 The malloc(3) implementation embedded in libc now uses sources imported 1353 as contrib/jemalloc. The most disruptive API change is to 1354 /etc/malloc.conf. If your system has an old-style /etc/malloc.conf, 1355 delete it prior to installworld, and optionally re-create it using the 1356 new format after rebooting. See malloc.conf(5) for details 1357 (specifically the TUNING section and the "opt.*" entries in the MALLCTL 1358 NAMESPACE section). 1359 136020120328: 1361 Big-endian MIPS TARGET_ARCH values no longer end in "eb". mips64eb 1362 is now spelled mips64. mipsn32eb is now spelled mipsn32. mipseb is 1363 now spelled mips. This is to aid compatibility with third-party 1364 software that expects this naming scheme in uname(3). Little-endian 1365 settings are unchanged. If you are updating a big-endian mips64 machine 1366 from before this change, you may need to set MACHINE_ARCH=mips64 in 1367 your environment before the new build system will recognize your machine. 1368 136920120306: 1370 Disable by default the option VFS_ALLOW_NONMPSAFE for all supported 1371 platforms. 1372 137320120229: 1374 Now unix domain sockets behave "as expected" on nullfs(5). Previously 1375 nullfs(5) did not pass through all behaviours to the underlying layer, 1376 as a result if we bound to a socket on the lower layer we could connect 1377 only to the lower path; if we bound to the upper layer we could connect 1378 only to the upper path. The new behavior is one can connect to both the 1379 lower and the upper paths regardless what layer path one binds to. 1380 138120120211: 1382 The getifaddrs upgrade path broken with 20111215 has been restored. 1383 If you have upgraded in between 20111215 and 20120209 you need to 1384 recompile libc again with your kernel. You still need to recompile 1385 world to be able to configure CARP but this restriction already 1386 comes from 20111215. 1387 138820120114: 1389 The set_rcvar() function has been removed from /etc/rc.subr. All 1390 base and ports rc.d scripts have been updated, so if you have a 1391 port installed with a script in /usr/local/etc/rc.d you can either 1392 hand-edit the rcvar= line, or reinstall the port. 1393 1394 An easy way to handle the mass-update of /etc/rc.d: 1395 rm /etc/rc.d/* && mergemaster -i 1396 139720120109: 1398 panic(9) now stops other CPUs in the SMP systems, disables interrupts 1399 on the current CPU and prevents other threads from running. 1400 This behavior can be reverted using the kern.stop_scheduler_on_panic 1401 tunable/sysctl. 1402 The new behavior can be incompatible with kern.sync_on_panic. 1403 140420111215: 1405 The carp(4) facility has been changed significantly. Configuration 1406 of the CARP protocol via ifconfig(8) has changed, as well as format 1407 of CARP events submitted to devd(8) has changed. See manual pages 1408 for more information. The arpbalance feature of carp(4) is currently 1409 not supported anymore. 1410 1411 Size of struct in_aliasreq, struct in6_aliasreq has changed. User 1412 utilities using SIOCAIFADDR, SIOCAIFADDR_IN6, e.g. ifconfig(8), 1413 need to be recompiled. 1414 141520111122: 1416 The acpi_wmi(4) status device /dev/wmistat has been renamed to 1417 /dev/wmistat0. 1418 141920111108: 1420 The option VFS_ALLOW_NONMPSAFE option has been added in order to 1421 explicitely support non-MPSAFE filesystems. 1422 It is on by default for all supported platform at this present 1423 time. 1424 142520111101: 1426 The broken amd(4) driver has been replaced with esp(4) in the amd64, 1427 i386 and pc98 GENERIC kernel configuration files. 1428 142920110930: 1430 sysinstall has been removed 1431 143220110923: 1433 The stable/9 branch created in subversion. This corresponds to the 1434 RELENG_9 branch in CVS. 1435 1436COMMON ITEMS: 1437 1438 General Notes 1439 ------------- 1440 Avoid using make -j when upgrading. While generally safe, there are 1441 sometimes problems using -j to upgrade. If your upgrade fails with 1442 -j, please try again without -j. From time to time in the past there 1443 have been problems using -j with buildworld and/or installworld. This 1444 is especially true when upgrading between "distant" versions (eg one 1445 that cross a major release boundary or several minor releases, or when 1446 several months have passed on the -current branch). 1447 1448 Sometimes, obscure build problems are the result of environment 1449 poisoning. This can happen because the make utility reads its 1450 environment when searching for values for global variables. To run 1451 your build attempts in an "environmental clean room", prefix all make 1452 commands with 'env -i '. See the env(1) manual page for more details. 1453 1454 When upgrading from one major version to another it is generally best 1455 to upgrade to the latest code in the currently installed branch first, 1456 then do an upgrade to the new branch. This is the best-tested upgrade 1457 path, and has the highest probability of being successful. Please try 1458 this approach before reporting problems with a major version upgrade. 1459 1460 When upgrading a live system, having a root shell around before 1461 installing anything can help undo problems. Not having a root shell 1462 around can lead to problems if pam has changed too much from your 1463 starting point to allow continued authentication after the upgrade. 1464 1465 This file should be read as a log of events. When a later event changes 1466 information of a prior event, the prior event should not be deleted. 1467 Instead, a pointer to the entry with the new information should be 1468 placed in the old entry. Readers of this file should also sanity check 1469 older entries before relying on them blindly. Authors of new entries 1470 should write them with this in mind. 1471 1472 ZFS notes 1473 --------- 1474 When upgrading the boot ZFS pool to a new version, always follow 1475 these two steps: 1476 1477 1.) recompile and reinstall the ZFS boot loader and boot block 1478 (this is part of "make buildworld" and "make installworld") 1479 1480 2.) update the ZFS boot block on your boot drive 1481 1482 The following example updates the ZFS boot block on the first 1483 partition (freebsd-boot) of a GPT partitioned drive ada0: 1484 "gpart bootcode -p /boot/gptzfsboot -i 1 ada0" 1485 1486 Non-boot pools do not need these updates. 1487 1488 To build a kernel 1489 ----------------- 1490 If you are updating from a prior version of FreeBSD (even one just 1491 a few days old), you should follow this procedure. It is the most 1492 failsafe as it uses a /usr/obj tree with a fresh mini-buildworld, 1493 1494 make kernel-toolchain 1495 make -DALWAYS_CHECK_MAKE buildkernel KERNCONF=YOUR_KERNEL_HERE 1496 make -DALWAYS_CHECK_MAKE installkernel KERNCONF=YOUR_KERNEL_HERE 1497 1498 To test a kernel once 1499 --------------------- 1500 If you just want to boot a kernel once (because you are not sure 1501 if it works, or if you want to boot a known bad kernel to provide 1502 debugging information) run 1503 make installkernel KERNCONF=YOUR_KERNEL_HERE KODIR=/boot/testkernel 1504 nextboot -k testkernel 1505 1506 To just build a kernel when you know that it won't mess you up 1507 -------------------------------------------------------------- 1508 This assumes you are already running a CURRENT system. Replace 1509 ${arch} with the architecture of your machine (e.g. "i386", 1510 "arm", "amd64", "ia64", "pc98", "sparc64", "powerpc", "mips", etc). 1511 1512 cd src/sys/${arch}/conf 1513 config KERNEL_NAME_HERE 1514 cd ../compile/KERNEL_NAME_HERE 1515 make depend 1516 make 1517 make install 1518 1519 If this fails, go to the "To build a kernel" section. 1520 1521 To rebuild everything and install it on the current system. 1522 ----------------------------------------------------------- 1523 # Note: sometimes if you are running current you gotta do more than 1524 # is listed here if you are upgrading from a really old current. 1525 1526 <make sure you have good level 0 dumps> 1527 make buildworld 1528 make kernel KERNCONF=YOUR_KERNEL_HERE 1529 [1] 1530 <reboot in single user> [3] 1531 mergemaster -Fp [5] 1532 make installworld 1533 mergemaster -Fi [4] 1534 make delete-old [6] 1535 <reboot> 1536 1537 To cross-install current onto a separate partition 1538 -------------------------------------------------- 1539 # In this approach we use a separate partition to hold 1540 # current's root, 'usr', and 'var' directories. A partition 1541 # holding "/", "/usr" and "/var" should be about 2GB in 1542 # size. 1543 1544 <make sure you have good level 0 dumps> 1545 <boot into -stable> 1546 make buildworld 1547 make buildkernel KERNCONF=YOUR_KERNEL_HERE 1548 <maybe newfs current's root partition> 1549 <mount current's root partition on directory ${CURRENT_ROOT}> 1550 make installworld DESTDIR=${CURRENT_ROOT} -DDB_FROM_SRC 1551 make distribution DESTDIR=${CURRENT_ROOT} # if newfs'd 1552 make installkernel KERNCONF=YOUR_KERNEL_HERE DESTDIR=${CURRENT_ROOT} 1553 cp /etc/fstab ${CURRENT_ROOT}/etc/fstab # if newfs'd 1554 <edit ${CURRENT_ROOT}/etc/fstab to mount "/" from the correct partition> 1555 <reboot into current> 1556 <do a "native" rebuild/install as described in the previous section> 1557 <maybe install compatibility libraries from ports/misc/compat*> 1558 <reboot> 1559 1560 1561 To upgrade in-place from stable to current 1562 ---------------------------------------------- 1563 <make sure you have good level 0 dumps> 1564 make buildworld [9] 1565 make kernel KERNCONF=YOUR_KERNEL_HERE [8] 1566 [1] 1567 <reboot in single user> [3] 1568 mergemaster -Fp [5] 1569 make installworld 1570 mergemaster -Fi [4] 1571 make delete-old [6] 1572 <reboot> 1573 1574 Make sure that you've read the UPDATING file to understand the 1575 tweaks to various things you need. At this point in the life 1576 cycle of current, things change often and you are on your own 1577 to cope. The defaults can also change, so please read ALL of 1578 the UPDATING entries. 1579 1580 Also, if you are tracking -current, you must be subscribed to 1581 freebsd-current@freebsd.org. Make sure that before you update 1582 your sources that you have read and understood all the recent 1583 messages there. If in doubt, please track -stable which has 1584 much fewer pitfalls. 1585 1586 [1] If you have third party modules, such as vmware, you 1587 should disable them at this point so they don't crash your 1588 system on reboot. 1589 1590 [3] From the bootblocks, boot -s, and then do 1591 fsck -p 1592 mount -u / 1593 mount -a 1594 cd src 1595 adjkerntz -i # if CMOS is wall time 1596 Also, when doing a major release upgrade, it is required that 1597 you boot into single user mode to do the installworld. 1598 1599 [4] Note: This step is non-optional. Failure to do this step 1600 can result in a significant reduction in the functionality of the 1601 system. Attempting to do it by hand is not recommended and those 1602 that pursue this avenue should read this file carefully, as well 1603 as the archives of freebsd-current and freebsd-hackers mailing lists 1604 for potential gotchas. The -U option is also useful to consider. 1605 See mergemaster(8) for more information. 1606 1607 [5] Usually this step is a noop. However, from time to time 1608 you may need to do this if you get unknown user in the following 1609 step. It never hurts to do it all the time. You may need to 1610 install a new mergemaster (cd src/usr.sbin/mergemaster && make 1611 install) after the buildworld before this step if you last updated 1612 from current before 20130425 or from -stable before 20130430. 1613 1614 [6] This only deletes old files and directories. Old libraries 1615 can be deleted by "make delete-old-libs", but you have to make 1616 sure that no program is using those libraries anymore. 1617 1618 [8] In order to have a kernel that can run the 4.x binaries needed to 1619 do an installworld, you must include the COMPAT_FREEBSD4 option in 1620 your kernel. Failure to do so may leave you with a system that is 1621 hard to boot to recover. A similar kernel option COMPAT_FREEBSD5 is 1622 required to run the 5.x binaries on more recent kernels. And so on 1623 for COMPAT_FREEBSD6 and COMPAT_FREEBSD7. 1624 1625 Make sure that you merge any new devices from GENERIC since the 1626 last time you updated your kernel config file. 1627 1628 [9] When checking out sources, you must include the -P flag to have 1629 cvs prune empty directories. 1630 1631 If CPUTYPE is defined in your /etc/make.conf, make sure to use the 1632 "?=" instead of the "=" assignment operator, so that buildworld can 1633 override the CPUTYPE if it needs to. 1634 1635 MAKEOBJDIRPREFIX must be defined in an environment variable, and 1636 not on the command line, or in /etc/make.conf. buildworld will 1637 warn if it is improperly defined. 1638FORMAT: 1639 1640This file contains a list, in reverse chronological order, of major 1641breakages in tracking -current. It is not guaranteed to be a complete 1642list of such breakages, and only contains entries since September 23, 2011. 1643If you need to see UPDATING entries from before that date, you will need 1644to fetch an UPDATING file from an older FreeBSD release. 1645 1646Copyright information: 1647 1648Copyright 1998-2009 M.
