UPDATING revision 327923
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 https://www.freebsd.org/doc/en_US.ISO8859-1/books/handbook/updating-src.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 1920180113: 20 The SW_WATCHDOG option is no longer necessary to enable the 21 hardclock-based software watchdog if no hardware watchdog is 22 configured. As before, SW_WATCHDOG will cause the software 23 watchdog to be enabled even if a hardware watchdog is configured. 24 2520180108: 26 lint(1) binaries and library are no longer built by default. To 27 enable building them, define WITH_LINT in src.conf. If you are using 28 a FreeBSD 12 or later system to build 11-stable, you may need to 29 install a lint(1) binary to use WITH_LINT. 30 3120171003: 32 When building multiple kernels using KERNCONF, non-existent KERNCONF 33 files will produce an error and buildkernel will fail. Previously 34 missing KERNCONF files silently failed giving no indication as to 35 why, only to subsequently discover during installkernel that the 36 desired kernel was never built in the first place. 37 3820170926: 39 Clang, llvm, lldb, compiler-rt and libc++ have been upgraded to 5.0.0. 40 Please see the 20141231 entry below for information about prerequisites 41 and upgrading, if you are not already using clang 3.5.0 or higher. 42 4320170822: 44 Since the switch to GPT disk labels, fsck for UFS/FFS has been 45 unable to automatically find alternate superblocks. As of r322806, 46 the information needed to find alternate superblocks has been 47 moved to the end of the area reserved for the boot block. 48 Filesystems created with a newfs of this vintage or later 49 will create the recovery information. If you have a filesystem 50 created prior to this change and wish to have a recovery block 51 created for your filesystem, you can do so by running fsck in 52 forground mode (i.e., do not use the -p or -y options). As it 53 starts, fsck will ask ``SAVE DATA TO FIND ALTERNATE SUPERBLOCKS'' 54 to which you should answer yes. 55 5620170518: 57 arm64 builds now use the base system LLD 4.0.0 linker by default, 58 instead of requiring that the aarch64-binutils port or package be 59 installed. To continue using aarch64-binutils, set 60 CROSS_BINUTILS_PREFIX=/usr/local/aarch64-freebsd/bin . 61 6220170529: 63 The ctl.ko module no longer implements the iSCSI target frontend: 64 cfiscsi.ko does instead. 65 66 If building cfiscsi.ko as a kernel module, the module can be loaded 67 via one of the following methods: 68 - `cfiscsi_load="YES"` in loader.conf(5). 69 - Add `cfiscsi` to `$kld_list` in rc.conf(5). 70 - ctladm(8)/ctld(8), when compiled with iSCSI support 71 (`WITH_ISCSI=yes` in src.conf(5)) 72 73 Please see cfiscsi(4) for more details. 74 7520170511: 76 The mmcsd.ko module now additionally depends on geom_flashmap.ko. 77 Also, mmc.ko and mmcsd.ko need to be a matching pair built from the 78 same source (previously, the dependency of mmcsd.ko on mmc.ko was 79 missing, but mmcsd.ko now will refuse to load if it is incompatible 80 with mmc.ko). 81 8220170414: 83 Binds and sends to the loopback addresses, IPv6 and IPv4, will now 84 use any explicitly assigned loopback address available in the jail 85 instead of using the first assigned address of the jail. 86 8720170413: 88 As of r316810 for ipfilter, keep frags is no longer assumed when 89 keep state is specified in a rule. r316810 aligns ipfilter with 90 documentation in man pages separating keep frags from keep state. 91 This allows keep state to specified without forcing keep frags 92 and allows keep frags to be specified independently of keep state. 93 To maintain previous behaviour, also specify keep frags with 94 keep state (as documented in ipf.conf.5). 95 9620170402: 97 Clang, llvm, lldb, compiler-rt and libc++ have been upgraded to 4.0.0. 98 Please see the 20141231 entry below for information about prerequisites 99 and upgrading, if you are not already using clang 3.5.0 or higher. 100 10120170323: 102 The code that provides support for ZFS .zfs/ directory functionality 103 has been reimplemented. It's not possible now to create a snapshot 104 by mkdir under .zfs/snapshot/. That should be the only user visible 105 change. 106 10720170319: 108 Many changes in the IPsec code have been merged from the FreeBSD-CURRENT 109 branch. The IPSEC_FILTERTUNNEL kernel option is removed in favour of 110 corresponding sysctl. The IPSEC_NAT_T kernel option is also removed, 111 and now NAT-T is supported by default. Security associations now use 112 the single namespace for SPI allocation, so if you use several manually 113 configured security associations with the same SPI, this configuration 114 needs modification. 115 11620161217: 117 Clang, llvm, lldb, compiler-rt and libc++ have been upgraded to 3.9.1. 118 Please see the 20141231 entry below for information about prerequisites 119 and upgrading, if you are not already using clang 3.5.0 or higher. 120 12120161124: 122 Clang, llvm, lldb, compiler-rt and libc++ have been upgraded to 3.9.0. 123 Please see the 20141231 entry below for information about prerequisites 124 and upgrading, if you are not already using clang 3.5.0 or higher. 125 12620161119: 127 The layout of the pmap structure has changed for powerpc to put the pmap 128 statistics at the front for all CPU variations. libkvm(3) and all tools 129 that link against it need to be recompiled. 130 13120161030: 132 isl(4) and cyapa(4) drivers now require a new driver, 133 chromebook_platform(4), to work properly on Chromebook-class hardware. 134 On other types of hardware the drivers may need to be configured using 135 device hints. Please see the corresponding manual pages for details. 136 13720161210: 138 Relocatable object files with the extension of .So have been renamed 139 to use an extension of .pico instead. The purpose of this change is 140 to avoid a name clash with shared libraries on case-insensitive file 141 systems. On those file systems, foo.So is the same file as foo.so. 142 14320160622: 144 The libc stub for the pipe(2) system call has been replaced with 145 a wrapper that calls the pipe2(2) system call and the pipe(2) 146 system call is now only implemented by the kernels that include 147 "options COMPAT_FREEBSD10" in their config file (this is the 148 default). Users should ensure that this option is enabled in 149 their kernel or upgrade userspace to r302092 before upgrading their 150 kernel. 151 15220160527: 153 CAM will now strip leading spaces from SCSI disks' serial numbers. 154 This will effect users who create UFS filesystems on SCSI disks using 155 those disk's diskid device nodes. For example, if /etc/fstab 156 previously contained a line like 157 "/dev/diskid/DISK-%20%20%20%20%20%20%20ABCDEFG0123456", you should 158 change it to "/dev/diskid/DISK-ABCDEFG0123456". Users of geom 159 transforms like gmirror may also be affected. ZFS users should 160 generally be fine. 161 16220160523: 163 The bitstring(3) API has been updated with new functionality and 164 improved performance. But it is binary-incompatible with the old API. 165 Objects built with the new headers may not be linked against objects 166 built with the old headers. 167 16820160520: 169 The brk and sbrk functions have been removed from libc on arm64. 170 Binutils from ports has been updated to not link to these 171 functions and should be updated to the latest version before 172 installing a new libc. 173 17420160517: 175 The armv6 port now defaults to hard float ABI. Limited support 176 for running both hardfloat and soft float on the same system 177 is available using the libraries installed with -DWITH_LIBSOFT. 178 This has only been tested as an upgrade path for installworld 179 and packages may fail or need manual intervention to run. New 180 packages will be needed. 181 182 To update an existing self-hosted armv6hf system, you must add 183 TARGET_ARCH=armv6 on the make command line for both the build 184 and the install steps. 185 18620160510: 187 Kernel modules compiled outside of a kernel build now default to 188 installing to /boot/modules instead of /boot/kernel. Many kernel 189 modules built this way (such as those in ports) already overrode 190 KMODDIR explicitly to install into /boot/modules. However, 191 manually building and installing a module from /sys/modules will 192 now install to /boot/modules instead of /boot/kernel. 193 19420160414: 195 The CAM I/O scheduler has been committed to the kernel. There should be 196 no user visible impact. This does enable NCQ Trim on ada SSDs. While the 197 list of known rogues that claim support for this but actually corrupt 198 data is believed to be complete, be on the lookout for data 199 corruption. The known rogue list is believed to be complete: 200 201 o Crucial MX100, M550 drives with MU01 firmware. 202 o Micron M510 and M550 drives with MU01 firmware. 203 o Micron M500 prior to MU07 firmware 204 o Samsung 830, 840, and 850 all firmwares 205 o FCCT M500 all firmwares 206 207 Crucial has firmware http://www.crucial.com/usa/en/support-ssd-firmware 208 with working NCQ TRIM. For Micron branded drives, see your sales rep for 209 updated firmware. Black listed drives will work correctly because these 210 drives work correctly so long as no NCQ TRIMs are sent to them. Given 211 this list is the same as found in Linux, it's believed there are no 212 other rogues in the market place. All other models from the above 213 vendors work. 214 215 To be safe, if you are at all concerned, you can quirk each of your 216 drives to prevent NCQ from being sent by setting: 217 kern.cam.ada.X.quirks="0x2" 218 in loader.conf. If the drive requires the 4k sector quirk, set the 219 quirks entry to 0x3. 220 22120160330: 222 The FAST_DEPEND build option has been removed and its functionality is 223 now the one true way. The old mkdep(1) style of 'make depend' has 224 been removed. See 20160311 for further details. 225 22620160317: 227 Resource range types have grown from unsigned long to uintmax_t. All 228 drivers, and anything using libdevinfo, need to be recompiled. 229 23020160311: 231 WITH_FAST_DEPEND is now enabled by default for in-tree and out-of-tree 232 builds. It no longer runs mkdep(1) during 'make depend', and the 233 'make depend' stage can safely be skipped now as it is auto ran 234 when building 'make all' and will generate all SRCS and DPSRCS before 235 building anything else. Dependencies are gathered at compile time with 236 -MF flags kept in separate .depend files per object file. Users should 237 run 'make cleandepend' once if using -DNO_CLEAN to clean out older 238 stale .depend files. 239 24020160306: 241 On amd64, clang 3.8.0 can now insert sections of type AMD64_UNWIND into 242 kernel modules. Therefore, if you load any kernel modules at boot time, 243 please install the boot loaders after you install the kernel, but before 244 rebooting, e.g.: 245 246 make buildworld 247 make kernel KERNCONF=YOUR_KERNEL_HERE 248 make -C sys/boot install 249 <reboot in single user> 250 251 Then follow the usual steps, described in the General Notes section, 252 below. 253 25420160305: 255 Clang, llvm, lldb and compiler-rt have been upgraded to 3.8.0. Please 256 see the 20141231 entry below for information about prerequisites and 257 upgrading, if you are not already using clang 3.5.0 or higher. 258 25920160301: 260 The AIO subsystem is now a standard part of the kernel. The 261 VFS_AIO kernel option and aio.ko kernel module have been removed. 262 Due to stability concerns, asynchronous I/O requests are only 263 permitted on sockets and raw disks by default. To enable 264 asynchronous I/O requests on all file types, set the 265 vfs.aio.enable_unsafe sysctl to a non-zero value. 266 26720160226: 268 The ELF object manipulation tool objcopy is now provided by the 269 ELF Tool Chain project rather than by GNU binutils. It should be a 270 drop-in replacement, with the addition of arm64 support. The 271 (temporary) src.conf knob WITHOUT_ELFCOPY_AS_OBJCOPY knob may be set 272 to obtain the GNU version if necessary. 273 27420160129: 275 Building ZFS pools on top of zvols is prohibited by default. That 276 feature has never worked safely; it's always been prone to deadlocks. 277 Using a zvol as the backing store for a VM guest's virtual disk will 278 still work, even if the guest is using ZFS. Legacy behavior can be 279 restored by setting vfs.zfs.vol.recursive=1. 280 28120160119: 282 The NONE and HPN patches has been removed from OpenSSH. They are 283 still available in the security/openssh-portable port. 284 28520160113: 286 With the addition of ypldap(8), a new _ypldap user is now required 287 during installworld. "mergemaster -p" can be used to add the user 288 prior to installworld, as documented in the handbook. 289 29020151216: 291 The tftp loader (pxeboot) now uses the option root-path directive. As a 292 consequence it no longer looks for a pxeboot.4th file on the tftp 293 server. Instead it uses the regular /boot infrastructure as with the 294 other loaders. 295 29620151211: 297 The code to start recording plug and play data into the modules has 298 been committed. While the old tools will properly build a new kernel, 299 a number of warnings about "unknown metadata record 4" will be produced 300 for an older kldxref. To avoid such warnings, make sure to rebuild 301 the kernel toolchain (or world). Make sure that you have r292078 or 302 later when trying to build 292077 or later before rebuilding. 303 30420151207: 305 Debug data files are now built by default with 'make buildworld' and 306 installed with 'make installworld'. This facilitates debugging but 307 requires more disk space both during the build and for the installed 308 world. Debug files may be disabled by setting WITHOUT_DEBUG_FILES=yes 309 in src.conf(5). 310 31120151130: 312 r291527 changed the internal interface between the nfsd.ko and 313 nfscommon.ko modules. As such, they must both be upgraded to-gether. 314 __FreeBSD_version has been bumped because of this. 315 31620151108: 317 Add support for unicode collation strings leads to a change of 318 order of files listed by ls(1) for example. To get back to the old 319 behaviour, set LC_COLLATE environment variable to "C". 320 321 Databases administrators will need to reindex their databases given 322 collation results will be different. 323 324 Due to a bug in install(1) it is recommended to remove the ancient 325 locales before running make installworld. 326 327 rm -rf /usr/share/locale/* 328 32920151030: 330 The OpenSSL has been upgraded to 1.0.2d. Any binaries requiring 331 libcrypto.so.7 or libssl.so.7 must be recompiled. 332 33320151020: 334 Qlogic 24xx/25xx firmware images were updated from 5.5.0 to 7.3.0. 335 Kernel modules isp_2400_multi and isp_2500_multi were removed and 336 should be replaced with isp_2400 and isp_2500 modules respectively. 337 33820151017: 339 The build previously allowed using 'make -n' to not recurse into 340 sub-directories while showing what commands would be executed, and 341 'make -n -n' to recursively show commands. Now 'make -n' will recurse 342 and 'make -N' will not. 343 34420151012: 345 If you specify SENDMAIL_MC or SENDMAIL_CF in make.conf, mergemaster 346 and etcupdate will now use this file. A custom sendmail.cf is now 347 updated via this mechanism rather than via installworld. If you had 348 excluded sendmail.cf in mergemaster.rc or etcupdate.conf, you may 349 want to remove the exclusion or change it to "always install". 350 /etc/mail/sendmail.cf is now managed the same way regardless of 351 whether SENDMAIL_MC/SENDMAIL_CF is used. If you are not using 352 SENDMAIL_MC/SENDMAIL_CF there should be no change in behavior. 353 35420151011: 355 Compatibility shims for legacy ATA device names have been removed. 356 It includes ATA_STATIC_ID kernel option, kern.cam.ada.legacy_aliases 357 and kern.geom.raid.legacy_aliases loader tunables, kern.devalias.* 358 environment variables, /dev/ad* and /dev/ar* symbolic links. 359 36020151006: 361 Clang, llvm, lldb, compiler-rt and libc++ have been upgraded to 3.7.0. 362 Please see the 20141231 entry below for information about prerequisites 363 and upgrading, if you are not already using clang 3.5.0 or higher. 364 36520150924: 366 Kernel debug files have been moved to /usr/lib/debug/boot/kernel/, 367 and renamed from .symbols to .debug. This reduces the size requirements 368 on the boot partition or file system and provides consistency with 369 userland debug files. 370 371 When using the supported kernel installation method the 372 /usr/lib/debug/boot/kernel directory will be renamed (to kernel.old) 373 as is done with /boot/kernel. 374 375 Developers wishing to maintain the historical behavior of installing 376 debug files in /boot/kernel/ can set KERN_DEBUGDIR="" in src.conf(5). 377 37820150827: 379 The wireless drivers had undergone changes that remove the 'parent 380 interface' from the ifconfig -l output. The rc.d network scripts 381 used to check presence of a parent interface in the list, so old 382 scripts would fail to start wireless networking. Thus, etcupdate(3) 383 or mergemaster(8) run is required after kernel update, to update your 384 rc.d scripts in /etc. 385 38620150827: 387 pf no longer supports 'scrub fragment crop' or 'scrub fragment drop-ovl' 388 These configurations are now automatically interpreted as 389 'scrub fragment reassemble'. 390 39120150817: 392 Kernel-loadable modules for the random(4) device are back. To use 393 them, the kernel must have 394 395 device random 396 options RANDOM_LOADABLE 397 398 kldload(8) can then be used to load random_fortuna.ko 399 or random_yarrow.ko. Please note that due to the indirect 400 function calls that the loadable modules need to provide, 401 the build-in variants will be slightly more efficient. 402 403 The random(4) kernel option RANDOM_DUMMY has been retired due to 404 unpopularity. It was not all that useful anyway. 405 40620150813: 407 The WITHOUT_ELFTOOLCHAIN_TOOLS src.conf(5) knob has been retired. 408 Control over building the ELF Tool Chain tools is now provided by 409 the WITHOUT_TOOLCHAIN knob. 410 41120150810: 412 The polarity of Pulse Per Second (PPS) capture events with the 413 uart(4) driver has been corrected. Prior to this change the PPS 414 "assert" event corresponded to the trailing edge of a positive PPS 415 pulse and the "clear" event was the leading edge of the next pulse. 416 417 As the width of a PPS pulse in a typical GPS receiver is on the 418 order of 1 millisecond, most users will not notice any significant 419 difference with this change. 420 421 Anyone who has compensated for the historical polarity reversal by 422 configuring a negative offset equal to the pulse width will need to 423 remove that workaround. 424 42520150809: 426 The default group assigned to /dev/dri entries has been changed 427 from 'wheel' to 'video' with the id of '44'. If you want to have 428 access to the dri devices please add yourself to the video group 429 with: 430 431 # pw groupmod video -m $USER 432 43320150806: 434 The menu.rc and loader.rc files will now be replaced during 435 upgrades. Please migrate local changes to menu.rc.local and 436 loader.rc.local instead. 437 43820150805: 439 GNU Binutils versions of addr2line, c++filt, nm, readelf, size, 440 strings and strip have been removed. The src.conf(5) knob 441 WITHOUT_ELFTOOLCHAIN_TOOLS no longer provides the binutils tools. 442 44320150728: 444 As ZFS requires more kernel stack pages than is the default on some 445 architectures e.g. i386, it now warns if KSTACK_PAGES is less than 446 ZFS_MIN_KSTACK_PAGES (which is 4 at the time of writing). 447 448 Please consider using 'options KSTACK_PAGES=X' where X is greater 449 than or equal to ZFS_MIN_KSTACK_PAGES i.e. 4 in such configurations. 450 45120150706: 452 sendmail has been updated to 8.15.2. Starting with FreeBSD 11.0 453 and sendmail 8.15, sendmail uses uncompressed IPv6 addresses by 454 default, i.e., they will not contain "::". For example, instead 455 of ::1, it will be 0:0:0:0:0:0:0:1. This permits a zero subnet 456 to have a more specific match, such as different map entries for 457 IPv6:0:0 vs IPv6:0. This change requires that configuration 458 data (including maps, files, classes, custom ruleset, etc.) must 459 use the same format, so make certain such configuration data is 460 upgrading. As a very simple check search for patterns like 461 'IPv6:[0-9a-fA-F:]*::' and 'IPv6::'. To return to the old 462 behavior, set the m4 option confUSE_COMPRESSED_IPV6_ADDRESSES or 463 the cf option UseCompressedIPv6Addresses. 464 46520150630: 466 The default kernel entropy-processing algorithm is now 467 Fortuna, replacing Yarrow. 468 469 Assuming you have 'device random' in your kernel config 470 file, the configurations allow a kernel option to override 471 this default. You may choose *ONE* of: 472 473 options RANDOM_YARROW # Legacy /dev/random algorithm. 474 options RANDOM_DUMMY # Blocking-only driver. 475 476 If you have neither, you get Fortuna. For most people, 477 read no further, Fortuna will give a /dev/random that works 478 like it always used to, and the difference will be irrelevant. 479 480 If you remove 'device random', you get *NO* kernel-processed 481 entropy at all. This may be acceptable to folks building 482 embedded systems, but has complications. Carry on reading, 483 and it is assumed you know what you need. 484 485 *PLEASE* read random(4) and random(9) if you are in the 486 habit of tweaking kernel configs, and/or if you are a member 487 of the embedded community, wanting specific and not-usual 488 behaviour from your security subsystems. 489 490 NOTE!! If you use RANDOM_DUMMY and/or have no 'device 491 random', you will NOT have a functioning /dev/random, and 492 many cryptographic features will not work, including SSH. 493 You may also find strange behaviour from the random(3) set 494 of library functions, in particular sranddev(3), srandomdev(3) 495 and arc4random(3). The reason for this is that the KERN_ARND 496 sysctl only returns entropy if it thinks it has some to 497 share, and with RANDOM_DUMMY or no 'device random' this 498 will never happen. 499 50020150623: 501 An additional fix for the issue described in the 20150614 sendmail 502 entry below has been been committed in revision 284717. 503 50420150616: 505 FreeBSD's old make (fmake) has been removed from the system. It is 506 available as the devel/fmake port or via pkg install fmake. 507 50820150615: 509 The fix for the issue described in the 20150614 sendmail entry 510 below has been been committed in revision 284436. The work 511 around described in that entry is no longer needed unless the 512 default setting is overridden by a confDH_PARAMETERS configuration 513 setting of '5' or pointing to a 512 bit DH parameter file. 514 51520150614: 516 ALLOW_DEPRECATED_ATF_TOOLS/ATFFILE support has been removed from 517 atf.test.mk (included from bsd.test.mk). Please upgrade devel/atf 518 and devel/kyua to version 0.20+ and adjust any calling code to work 519 with Kyuafile and kyua. 520 52120150614: 522 The import of openssl to address the FreeBSD-SA-15:10.openssl 523 security advisory includes a change which rejects handshakes 524 with DH parameters below 768 bits. sendmail releases prior 525 to 8.15.2 (not yet released), defaulted to a 512 bit 526 DH parameter setting for client connections. To work around 527 this interoperability, sendmail can be configured to use a 528 2048 bit DH parameter by: 529 530 1. Edit /etc/mail/`hostname`.mc 531 2. If a setting for confDH_PARAMETERS does not exist or 532 exists and is set to a string beginning with '5', 533 replace it with '2'. 534 3. If a setting for confDH_PARAMETERS exists and is set to 535 a file path, create a new file with: 536 openssl dhparam -out /path/to/file 2048 537 4. Rebuild the .cf file: 538 cd /etc/mail/; make; make install 539 5. Restart sendmail: 540 cd /etc/mail/; make restart 541 542 A sendmail patch is coming, at which time this file will be 543 updated. 544 54520150604: 546 Generation of legacy formatted entries have been disabled by default 547 in pwd_mkdb(8), as all base system consumers of the legacy formatted 548 entries were converted to use the new format by default when the new, 549 machine independent format have been added and supported since FreeBSD 550 5.x. 551 552 Please see the pwd_mkdb(8) manual page for further details. 553 55420150525: 555 Clang and llvm have been upgraded to 3.6.1 release. Please see the 556 20141231 entry below for information about prerequisites and upgrading, 557 if you are not already using 3.5.0 or higher. 558 55920150521: 560 TI platform code switched to using vendor DTS files and this update 561 may break existing systems running on Beaglebone, Beaglebone Black, 562 and Pandaboard: 563 564 - dtb files should be regenerated/reinstalled. Filenames are the 565 same but content is different now 566 - GPIO addressing was changed, now each GPIO bank (32 pins per bank) 567 has its own /dev/gpiocX device, e.g. pin 121 on /dev/gpioc0 in old 568 addressing scheme is now pin 25 on /dev/gpioc3. 569 - Pandaboard: /etc/ttys should be updated, serial console device is 570 now /dev/ttyu2, not /dev/ttyu0 571 57220150501: 573 soelim(1) from gnu/usr.bin/groff has been replaced by usr.bin/soelim. 574 If you need the GNU extension from groff soelim(1), install groff 575 from package: pkg install groff, or via ports: textproc/groff. 576 57720150423: 578 chmod, chflags, chown and chgrp now affect symlinks in -R mode as 579 defined in symlink(7); previously symlinks were silently ignored. 580 58120150415: 582 The const qualifier has been removed from iconv(3) to comply with 583 POSIX. The ports tree is aware of this from r384038 onwards. 584 58520150416: 586 Libraries specified by LIBADD in Makefiles must have a corresponding 587 DPADD_<lib> variable to ensure correct dependencies. This is now 588 enforced in src.libnames.mk. 589 59020150324: 591 From legacy ata(4) driver was removed support for SATA controllers 592 supported by more functional drivers ahci(4), siis(4) and mvs(4). 593 Kernel modules ataahci and ataadaptec were removed completely, 594 replaced by ahci and mvs modules respectively. 595 59620150315: 597 Clang, llvm and lldb have been upgraded to 3.6.0 release. Please see 598 the 20141231 entry below for information about prerequisites and 599 upgrading, if you are not already using 3.5.0 or higher. 600 60120150307: 602 The 32-bit PowerPC kernel has been changed to a position-independent 603 executable. This can only be booted with a version of loader(8) 604 newer than January 31, 2015, so make sure to update both world and 605 kernel before rebooting. 606 60720150217: 608 If you are running a -CURRENT kernel since r273872 (Oct 30th, 2014), 609 but before r278950, the RNG was not seeded properly. Immediately 610 upgrade the kernel to r278950 or later and regenerate any keys (e.g. 611 ssh keys or openssl keys) that were generated w/ a kernel from that 612 range. This does not affect programs that directly used /dev/random 613 or /dev/urandom. All userland uses of arc4random(3) are affected. 614 61520150210: 616 The autofs(4) ABI was changed in order to restore binary compatibility 617 with 10.1-RELEASE. The automountd(8) daemon needs to be rebuilt to work 618 with the new kernel. 619 62020150131: 621 The powerpc64 kernel has been changed to a position-independent 622 executable. This can only be booted with a new version of loader(8), 623 so make sure to update both world and kernel before rebooting. 624 62520150118: 626 Clang and llvm have been upgraded to 3.5.1 release. This is a bugfix 627 only release, no new features have been added. Please see the 20141231 628 entry below for information about prerequisites and upgrading, if you 629 are not already using 3.5.0. 630 63120150107: 632 ELF tools addr2line, elfcopy (strip), nm, size, and strings are now 633 taken from the ELF Tool Chain project rather than GNU binutils. They 634 should be drop-in replacements, with the addition of arm64 support. 635 The WITHOUT_ELFTOOLCHAIN_TOOLS= knob may be used to obtain the 636 binutils tools, if necessary. See 20150805 for updated information. 637 63820150105: 639 The default Unbound configuration now enables remote control 640 using a local socket. Users who have already enabled the 641 local_unbound service should regenerate their configuration 642 by running "service local_unbound setup" as root. 643 64420150102: 645 The GNU texinfo and GNU info pages have been removed. 646 To be able to view GNU info pages please install texinfo from ports. 647 64820141231: 649 Clang, llvm and lldb have been upgraded to 3.5.0 release. 650 651 As of this release, a prerequisite for building clang, llvm and lldb is 652 a C++11 capable compiler and C++11 standard library. This means that to 653 be able to successfully build the cross-tools stage of buildworld, with 654 clang as the bootstrap compiler, your system compiler or cross compiler 655 should either be clang 3.3 or later, or gcc 4.8 or later, and your 656 system C++ library should be libc++, or libdstdc++ from gcc 4.8 or 657 later. 658 659 On any standard FreeBSD 10.x or 11.x installation, where clang and 660 libc++ are on by default (that is, on x86 or arm), this should work out 661 of the box. 662 663 On 9.x installations where clang is enabled by default, e.g. on x86 and 664 powerpc, libc++ will not be enabled by default, so libc++ should be 665 built (with clang) and installed first. If both clang and libc++ are 666 missing, build clang first, then use it to build libc++. 667 668 On 8.x and earlier installations, upgrade to 9.x first, and then follow 669 the instructions for 9.x above. 670 671 Sparc64 and mips users are unaffected, as they still use gcc 4.2.1 by 672 default, and do not build clang. 673 674 Many embedded systems are resource constrained, and will not be able to 675 build clang in a reasonable time, or in some cases at all. In those 676 cases, cross building bootable systems on amd64 is a workaround. 677 678 This new version of clang introduces a number of new warnings, of which 679 the following are most likely to appear: 680 681 -Wabsolute-value 682 683 This warns in two cases, for both C and C++: 684 * When the code is trying to take the absolute value of an unsigned 685 quantity, which is effectively a no-op, and almost never what was 686 intended. The code should be fixed, if at all possible. If you are 687 sure that the unsigned quantity can be safely cast to signed, without 688 loss of information or undefined behavior, you can add an explicit 689 cast, or disable the warning. 690 691 * When the code is trying to take an absolute value, but the called 692 abs() variant is for the wrong type, which can lead to truncation. 693 If you want to disable the warning instead of fixing the code, please 694 make sure that truncation will not occur, or it might lead to unwanted 695 side-effects. 696 697 -Wtautological-undefined-compare and 698 -Wundefined-bool-conversion 699 700 These warn when C++ code is trying to compare 'this' against NULL, while 701 'this' should never be NULL in well-defined C++ code. However, there is 702 some legacy (pre C++11) code out there, which actively abuses this 703 feature, which was less strictly defined in previous C++ versions. 704 705 Squid and openjdk do this, for example. The warning can be turned off 706 for C++98 and earlier, but compiling the code in C++11 mode might result 707 in unexpected behavior; for example, the parts of the program that are 708 unreachable could be optimized away. 709 71020141222: 711 The old NFS client and server (kernel options NFSCLIENT, NFSSERVER) 712 kernel sources have been removed. The .h files remain, since some 713 utilities include them. This will need to be fixed later. 714 If "mount -t oldnfs ..." is attempted, it will fail. 715 If the "-o" option on mountd(8), nfsd(8) or nfsstat(1) is used, 716 the utilities will report errors. 717 71820141121: 719 The handling of LOCAL_LIB_DIRS has been altered to skip addition of 720 directories to top level SUBDIR variable when their parent 721 directory is included in LOCAL_DIRS. Users with build systems with 722 such hierarchies and without SUBDIR entries in the parent 723 directory Makefiles should add them or add the directories to 724 LOCAL_DIRS. 725 72620141109: 727 faith(4) and faithd(8) have been removed from the base system. Faith 728 has been obsolete for a very long time. 729 73020141104: 731 vt(4), the new console driver, is enabled by default. It brings 732 support for Unicode and double-width characters, as well as 733 support for UEFI and integration with the KMS kernel video 734 drivers. 735 736 You may need to update your console settings in /etc/rc.conf, 737 most probably the keymap. During boot, /etc/rc.d/syscons will 738 indicate what you need to do. 739 740 vt(4) still has issues and lacks some features compared to 741 syscons(4). See the wiki for up-to-date information: 742 https://wiki.freebsd.org/Newcons 743 744 If you want to keep using syscons(4), you can do so by adding 745 the following line to /boot/loader.conf: 746 kern.vty=sc 747 74820141102: 749 pjdfstest has been integrated into kyua as an opt-in test suite. 750 Please see share/doc/pjdfstest/README for more details on how to 751 execute it. 752 75320141009: 754 gperf has been removed from the base system for architectures 755 that use clang. Ports that require gperf will obtain it from the 756 devel/gperf port. 757 75820140923: 759 pjdfstest has been moved from tools/regression/pjdfstest to 760 contrib/pjdfstest . 761 76220140922: 763 At svn r271982, The default linux compat kernel ABI has been adjusted 764 to 2.6.18 in support of the linux-c6 compat ports infrastructure 765 update. If you wish to continue using the linux-f10 compat ports, 766 add compat.linux.osrelease=2.6.16 to your local sysctl.conf. Users are 767 encouraged to update their linux-compat packages to linux-c6 during 768 their next update cycle. 769 77020140729: 771 The ofwfb driver, used to provide a graphics console on PowerPC when 772 using vt(4), no longer allows mmap() of all physical memory. This 773 will prevent Xorg on PowerPC with some ATI graphics cards from 774 initializing properly unless x11-servers/xorg-server is updated to 775 1.12.4_8 or newer. 776 77720140723: 778 The xdev targets have been converted to using TARGET and 779 TARGET_ARCH instead of XDEV and XDEV_ARCH. 780 78120140719: 782 The default unbound configuration has been modified to address 783 issues with reverse lookups on networks that use private 784 address ranges. If you use the local_unbound service, run 785 "service local_unbound setup" as root to regenerate your 786 configuration, then "service local_unbound reload" to load the 787 new configuration. 788 78920140709: 790 The GNU texinfo and GNU info pages are not built and installed 791 anymore, WITH_INFO knob has been added to allow to built and install 792 them again. 793 UPDATE: see 20150102 entry on texinfo's removal 794 79520140708: 796 The GNU readline library is now an INTERNALLIB - that is, it is 797 statically linked into consumers (GDB and variants) in the base 798 system, and the shared library is no longer installed. The 799 devel/readline port is available for third party software that 800 requires readline. 801 80220140702: 803 The Itanium architecture (ia64) has been removed from the list of 804 known architectures. This is the first step in the removal of the 805 architecture. 806 80720140701: 808 Commit r268115 has added NFSv4.1 server support, merged from 809 projects/nfsv4.1-server. Since this includes changes to the 810 internal interfaces between the NFS related modules, a full 811 build of the kernel and modules will be necessary. 812 __FreeBSD_version has been bumped. 813 81420140629: 815 The WITHOUT_VT_SUPPORT kernel config knob has been renamed 816 WITHOUT_VT. (The other _SUPPORT knobs have a consistent meaning 817 which differs from the behaviour controlled by this knob.) 818 81920140619: 820 Maximal length of the serial number in CTL was increased from 16 to 821 64 chars, that breaks ABI. All CTL-related tools, such as ctladm 822 and ctld, need to be rebuilt to work with a new kernel. 823 82420140606: 825 The libatf-c and libatf-c++ major versions were downgraded to 0 and 826 1 respectively to match the upstream numbers. They were out of 827 sync because, when they were originally added to FreeBSD, the 828 upstream versions were not respected. These libraries are private 829 and not yet built by default, so renumbering them should be a 830 non-issue. However, unclean source trees will yield broken test 831 programs once the operator executes "make delete-old-libs" after a 832 "make installworld". 833 834 Additionally, the atf-sh binary was made private by moving it into 835 /usr/libexec/. Already-built shell test programs will keep the 836 path to the old binary so they will break after "make delete-old" 837 is run. 838 839 If you are using WITH_TESTS=yes (not the default), wipe the object 840 tree and rebuild from scratch to prevent spurious test failures. 841 This is only needed once: the misnumbered libraries and misplaced 842 binaries have been added to OptionalObsoleteFiles.inc so they will 843 be removed during a clean upgrade. 844 84520140512: 846 Clang and llvm have been upgraded to 3.4.1 release. 847 84820140508: 849 We bogusly installed src.opts.mk in /usr/share/mk. This file should 850 be removed to avoid issues in the future (and has been added to 851 ObsoleteFiles.inc). 852 85320140505: 854 /etc/src.conf now affects only builds of the FreeBSD src tree. In the 855 past, it affected all builds that used the bsd.*.mk files. The old 856 behavior was a bug, but people may have relied upon it. To get this 857 behavior back, you can .include /etc/src.conf from /etc/make.conf 858 (which is still global and isn't changed). This also changes the 859 behavior of incremental builds inside the tree of individual 860 directories. Set MAKESYSPATH to ".../share/mk" to do that. 861 Although this has survived make universe and some upgrade scenarios, 862 other upgrade scenarios may have broken. At least one form of 863 temporary breakage was fixed with MAKESYSPATH settings for buildworld 864 as well... In cases where MAKESYSPATH isn't working with this 865 setting, you'll need to set it to the full path to your tree. 866 867 One side effect of all this cleaning up is that bsd.compiler.mk 868 is no longer implicitly included by bsd.own.mk. If you wish to 869 use COMPILER_TYPE, you must now explicitly include bsd.compiler.mk 870 as well. 871 87220140430: 873 The lindev device has been removed since /dev/full has been made a 874 standard device. __FreeBSD_version has been bumped. 875 87620140424: 877 The knob WITHOUT_VI was added to the base system, which controls 878 building ex(1), vi(1), etc. Older releases of FreeBSD required ex(1) 879 in order to reorder files share/termcap and didn't build ex(1) as a 880 build tool, so building/installing with WITH_VI is highly advised for 881 build hosts for older releases. 882 883 This issue has been fixed in stable/9 and stable/10 in r277022 and 884 r276991, respectively. 885 88620140418: 887 The YES_HESIOD knob has been removed. It has been obsolete for 888 a decade. Please move to using WITH_HESIOD instead or your builds 889 will silently lack HESIOD. 890 89120140405: 892 The uart(4) driver has been changed with respect to its handling 893 of the low-level console. Previously the uart(4) driver prevented 894 any process from changing the baudrate or the CLOCAL and HUPCL 895 control flags. By removing the restrictions, operators can make 896 changes to the serial console port without having to reboot. 897 However, when getty(8) is started on the serial device that is 898 associated with the low-level console, a misconfigured terminal 899 line in /etc/ttys will now have a real impact. 900 Before upgrading the kernel, make sure that /etc/ttys has the 901 serial console device configured as 3wire without baudrate to 902 preserve the previous behaviour. E.g: 903 ttyu0 "/usr/libexec/getty 3wire" vt100 on secure 904 90520140306: 906 Support for libwrap (TCP wrappers) in rpcbind was disabled by default 907 to improve performance. To re-enable it, if needed, run rpcbind 908 with command line option -W. 909 91020140226: 911 Switched back to the GPL dtc compiler due to updates in the upstream 912 dts files not being supported by the BSDL dtc compiler. You will need 913 to rebuild your kernel toolchain to pick up the new compiler. Core dumps 914 may result while building dtb files during a kernel build if you fail 915 to do so. Set WITHOUT_GPL_DTC if you require the BSDL compiler. 916 91720140216: 918 Clang and llvm have been upgraded to 3.4 release. 919 92020140216: 921 The nve(4) driver has been removed. Please use the nfe(4) driver 922 for NVIDIA nForce MCP Ethernet adapters instead. 923 92420140212: 925 An ABI incompatibility crept into the libc++ 3.4 import in r261283. 926 This could cause certain C++ applications using shared libraries built 927 against the previous version of libc++ to crash. The incompatibility 928 has now been fixed, but any C++ applications or shared libraries built 929 between r261283 and r261801 should be recompiled. 930 93120140204: 932 OpenSSH will now ignore errors caused by kernel lacking of Capsicum 933 capability mode support. Please note that enabling the feature in 934 kernel is still highly recommended. 935 93620140131: 937 OpenSSH is now built with sandbox support, and will use sandbox as 938 the default privilege separation method. This requires Capsicum 939 capability mode support in kernel. 940 94120140128: 942 The libelf and libdwarf libraries have been updated to newer 943 versions from upstream. Shared library version numbers for 944 these two libraries were bumped. Any ports or binaries 945 requiring these two libraries should be recompiled. 946 __FreeBSD_version is bumped to 1100006. 947 94820140110: 949 If a Makefile in a tests/ directory was auto-generating a Kyuafile 950 instead of providing an explicit one, this would prevent such 951 Makefile from providing its own Kyuafile in the future during 952 NO_CLEAN builds. This has been fixed in the Makefiles but manual 953 intervention is needed to clean an objdir if you use NO_CLEAN: 954 # find /usr/obj -name Kyuafile | xargs rm -f 955 95620131213: 957 The behavior of gss_pseudo_random() for the krb5 mechanism 958 has changed, for applications requesting a longer random string 959 than produced by the underlying enctype's pseudo-random() function. 960 In particular, the random string produced from a session key of 961 enctype aes256-cts-hmac-sha1-96 or aes256-cts-hmac-sha1-96 will 962 be different at the 17th octet and later, after this change. 963 The counter used in the PRF+ construction is now encoded as a 964 big-endian integer in accordance with RFC 4402. 965 __FreeBSD_version is bumped to 1100004. 966 96720131108: 968 The WITHOUT_ATF build knob has been removed and its functionality 969 has been subsumed into the more generic WITHOUT_TESTS. If you were 970 using the former to disable the build of the ATF libraries, you 971 should change your settings to use the latter. 972 97320131025: 974 The default version of mtree is nmtree which is obtained from 975 NetBSD. The output is generally the same, but may vary 976 slightly. If you found you need identical output adding 977 "-F freebsd9" to the command line should do the trick. For the 978 time being, the old mtree is available as fmtree. 979 98020131014: 981 libbsdyml has been renamed to libyaml and moved to /usr/lib/private. 982 This will break ports-mgmt/pkg. Rebuild the port, or upgrade to pkg 983 1.1.4_8 and verify bsdyml not linked in, before running "make 984 delete-old-libs": 985 # make -C /usr/ports/ports-mgmt/pkg build deinstall install clean 986 or 987 # pkg install pkg; ldd /usr/local/sbin/pkg | grep bsdyml 988 98920131010: 990 The stable/10 branch has been created in subversion from head 991 revision r256279. 992 99320131010: 994 The rc.d/jail script has been updated to support jail(8) 995 configuration file. The "jail_<jname>_*" rc.conf(5) variables 996 for per-jail configuration are automatically converted to 997 /var/run/jail.<jname>.conf before the jail(8) utility is invoked. 998 This is transparently backward compatible. See below about some 999 incompatibilities and rc.conf(5) manual page for more details. 1000 1001 These variables are now deprecated in favor of jail(8) configuration 1002 file. One can use "rc.d/jail config <jname>" command to generate 1003 a jail(8) configuration file in /var/run/jail.<jname>.conf without 1004 running the jail(8) utility. The default pathname of the 1005 configuration file is /etc/jail.conf and can be specified by 1006 using $jail_conf or $jail_<jname>_conf variables. 1007 1008 Please note that jail_devfs_ruleset accepts an integer at 1009 this moment. Please consider to rewrite the ruleset name 1010 with an integer. 1011 101220130930: 1013 BIND has been removed from the base system. If all you need 1014 is a local resolver, simply enable and start the local_unbound 1015 service instead. Otherwise, several versions of BIND are 1016 available in the ports tree. The dns/bind99 port is one example. 1017 1018 With this change, nslookup(1) and dig(1) are no longer in the base 1019 system. Users should instead use host(1) and drill(1) which are 1020 in the base system. Alternatively, nslookup and dig can 1021 be obtained by installing the dns/bind-tools port. 1022 102320130916: 1024 With the addition of unbound(8), a new unbound user is now 1025 required during installworld. "mergemaster -p" can be used to 1026 add the user prior to installworld, as documented in the handbook. 1027 102820130911: 1029 OpenSSH is now built with DNSSEC support, and will by default 1030 silently trust signed SSHFP records. This can be controlled with 1031 the VerifyHostKeyDNS client configuration setting. DNSSEC support 1032 can be disabled entirely with the WITHOUT_LDNS option in src.conf. 1033 103420130906: 1035 The GNU Compiler Collection and C++ standard library (libstdc++) 1036 are no longer built by default on platforms where clang is the system 1037 compiler. You can enable them with the WITH_GCC and WITH_GNUCXX 1038 options in src.conf. 1039 104020130905: 1041 The PROCDESC kernel option is now part of the GENERIC kernel 1042 configuration and is required for the rwhod(8) to work. 1043 If you are using custom kernel configuration, you should include 1044 'options PROCDESC'. 1045 104620130905: 1047 The API and ABI related to the Capsicum framework was modified 1048 in backward incompatible way. The userland libraries and programs 1049 have to be recompiled to work with the new kernel. This includes the 1050 following libraries and programs, but the whole buildworld is 1051 advised: libc, libprocstat, dhclient, tcpdump, hastd, hastctl, 1052 kdump, procstat, rwho, rwhod, uniq. 1053 105420130903: 1055 AES-NI intrinsic support has been added to gcc. The AES-NI module 1056 has been updated to use this support. A new gcc is required to build 1057 the aesni module on both i386 and amd64. 1058 105920130821: 1060 The PADLOCK_RNG and RDRAND_RNG kernel options are now devices. 1061 Thus "device padlock_rng" and "device rdrand_rng" should be 1062 used instead of "options PADLOCK_RNG" & "options RDRAND_RNG". 1063 106420130813: 1065 WITH_ICONV has been split into two feature sets. WITH_ICONV now 1066 enables just the iconv* functionality and is now on by default. 1067 WITH_LIBICONV_COMPAT enables the libiconv api and link time 1068 compatibility. Set WITHOUT_ICONV to build the old way. 1069 If you have been using WITH_ICONV before, you will very likely 1070 need to turn on WITH_LIBICONV_COMPAT. 1071 107220130806: 1073 INVARIANTS option now enables DEBUG for code with OpenSolaris and 1074 Illumos origin, including ZFS. If you have INVARIANTS in your 1075 kernel configuration, then there is no need to set DEBUG or ZFS_DEBUG 1076 explicitly. 1077 DEBUG used to enable witness(9) tracking of OpenSolaris (mostly ZFS) 1078 locks if WITNESS option was set. Because that generated a lot of 1079 witness(9) reports and all of them were believed to be false 1080 positives, this is no longer done. New option OPENSOLARIS_WITNESS 1081 can be used to achieve the previous behavior. 1082 108320130806: 1084 Timer values in IPv6 data structures now use time_uptime instead 1085 of time_second. Although this is not a user-visible functional 1086 change, userland utilities which directly use them---ndp(8), 1087 rtadvd(8), and rtsold(8) in the base system---need to be updated 1088 to r253970 or later. 1089 109020130802: 1091 find -delete can now delete the pathnames given as arguments, 1092 instead of only files found below them or if the pathname did 1093 not contain any slashes. Formerly, the following error message 1094 would result: 1095 1096 find: -delete: <path>: relative path potentially not safe 1097 1098 Deleting the pathnames given as arguments can be prevented 1099 without error messages using -mindepth 1 or by changing 1100 directory and passing "." as argument to find. This works in the 1101 old as well as the new version of find. 1102 110320130726: 1104 Behavior of devfs rules path matching has been changed. 1105 Pattern is now always matched against fully qualified devfs 1106 path and slash characters must be explicitly matched by 1107 slashes in pattern (FNM_PATHNAME). Rulesets involving devfs 1108 subdirectories must be reviewed. 1109 111020130716: 1111 The default ARM ABI has changed to the ARM EABI. The old ABI is 1112 incompatible with the ARM EABI and all programs and modules will 1113 need to be rebuilt to work with a new kernel. 1114 1115 To keep using the old ABI ensure the WITHOUT_ARM_EABI knob is set. 1116 1117 NOTE: Support for the old ABI will be removed in the future and 1118 users are advised to upgrade. 1119 112020130709: 1121 pkg_install has been disconnected from the build if you really need it 1122 you should add WITH_PKGTOOLS in your src.conf(5). 1123 112420130709: 1125 Most of network statistics structures were changed to be able 1126 keep 64-bits counters. Thus all tools, that work with networking 1127 statistics, must be rebuilt (netstat(1), bsnmpd(1), etc.) 1128 112920130618: 1130 Fix a bug that allowed a tracing process (e.g. gdb) to write 1131 to a memory-mapped file in the traced process's address space 1132 even if neither the traced process nor the tracing process had 1133 write access to that file. 1134 113520130615: 1136 CVS has been removed from the base system. An exact copy 1137 of the code is available from the devel/cvs port. 1138 113920130613: 1140 Some people report the following error after the switch to bmake: 1141 1142 make: illegal option -- J 1143 usage: make [-BPSXeiknpqrstv] [-C directory] [-D variable] 1144 ... 1145 *** [buildworld] Error code 2 1146 1147 this likely due to an old instance of make in 1148 ${MAKEPATH} (${MAKEOBJDIRPREFIX}${.CURDIR}/make.${MACHINE}) 1149 which src/Makefile will use that blindly, if it exists, so if 1150 you see the above error: 1151 1152 rm -rf `make -V MAKEPATH` 1153 1154 should resolve it. 1155 115620130516: 1157 Use bmake by default. 1158 Whereas before one could choose to build with bmake via 1159 -DWITH_BMAKE one must now use -DWITHOUT_BMAKE to use the old 1160 make. The goal is to remove these knobs for 10-RELEASE. 1161 1162 It is worth noting that bmake (like gmake) treats the command 1163 line as the unit of failure, rather than statements within the 1164 command line. Thus '(cd some/where && dosomething)' is safer 1165 than 'cd some/where; dosomething'. The '()' allows consistent 1166 behavior in parallel build. 1167 116820130429: 1169 Fix a bug that allows NFS clients to issue READDIR on files. 1170 117120130426: 1172 The WITHOUT_IDEA option has been removed because 1173 the IDEA patent expired. 1174 117520130426: 1176 The sysctl which controls TRIM support under ZFS has been renamed 1177 from vfs.zfs.trim_disable -> vfs.zfs.trim.enabled and has been 1178 enabled by default. 1179 118020130425: 1181 The mergemaster command now uses the default MAKEOBJDIRPREFIX 1182 rather than creating it's own in the temporary directory in 1183 order allow access to bootstrapped versions of tools such as 1184 install and mtree. When upgrading from version of FreeBSD where 1185 the install command does not support -l, you will need to 1186 install a new mergemaster command if mergemaster -p is required. 1187 This can be accomplished with the command (cd src/usr.sbin/mergemaster 1188 && make install). 1189 119020130404: 1191 Legacy ATA stack, disabled and replaced by new CAM-based one since 1192 FreeBSD 9.0, completely removed from the sources. Kernel modules 1193 atadisk and atapi*, user-level tools atacontrol and burncd are 1194 removed. Kernel option `options ATA_CAM` is now permanently enabled 1195 and removed. 1196 119720130319: 1198 SOCK_CLOEXEC and SOCK_NONBLOCK flags have been added to socket(2) 1199 and socketpair(2). Software, in particular Kerberos, may 1200 automatically detect and use these during building. The resulting 1201 binaries will not work on older kernels. 1202 120320130308: 1204 CTL_DISABLE has also been added to the sparc64 GENERIC (for further 1205 information, see the respective 20130304 entry). 1206 120720130304: 1208 Recent commits to callout(9) changed the size of struct callout, 1209 so the KBI is probably heavily disturbed. Also, some functions 1210 in callout(9)/sleep(9)/sleepqueue(9)/condvar(9) KPIs were replaced 1211 by macros. Every kernel module using it won't load, so rebuild 1212 is requested. 1213 1214 The ctl device has been re-enabled in GENERIC for i386 and amd64, 1215 but does not initialize by default (because of the new CTL_DISABLE 1216 option) to save memory. To re-enable it, remove the CTL_DISABLE 1217 option from the kernel config file or set kern.cam.ctl.disable=0 1218 in /boot/loader.conf. 1219 122020130301: 1221 The ctl device has been disabled in GENERIC for i386 and amd64. 1222 This was done due to the extra memory being allocated at system 1223 initialisation time by the ctl driver which was only used if 1224 a CAM target device was created. This makes a FreeBSD system 1225 unusable on 128MB or less of RAM. 1226 122720130208: 1228 A new compression method (lz4) has been merged to -HEAD. Please 1229 refer to zpool-features(7) for more information. 1230 1231 Please refer to the "ZFS notes" section of this file for information 1232 on upgrading boot ZFS pools. 1233 123420130129: 1235 A BSD-licensed patch(1) variant has been added and is installed 1236 as bsdpatch, being the GNU version the default patch. 1237 To inverse the logic and use the BSD-licensed one as default, 1238 while having the GNU version installed as gnupatch, rebuild 1239 and install world with the WITH_BSD_PATCH knob set. 1240 124120130121: 1242 Due to the use of the new -l option to install(1) during build 1243 and install, you must take care not to directly set the INSTALL 1244 make variable in your /etc/make.conf, /etc/src.conf, or on the 1245 command line. If you wish to use the -C flag for all installs 1246 you may be able to add INSTALL+=-C to /etc/make.conf or 1247 /etc/src.conf. 1248 124920130118: 1250 The install(1) option -M has changed meaning and now takes an 1251 argument that is a file or path to append logs to. In the 1252 unlikely event that -M was the last option on the command line 1253 and the command line contained at least two files and a target 1254 directory the first file will have logs appended to it. The -M 1255 option served little practical purpose in the last decade so its 1256 use is expected to be extremely rare. 1257 125820121223: 1259 After switching to Clang as the default compiler some users of ZFS 1260 on i386 systems started to experience stack overflow kernel panics. 1261 Please consider using 'options KSTACK_PAGES=4' in such configurations. 1262 126320121222: 1264 GEOM_LABEL now mangles label names read from file system metadata. 1265 Mangling affect labels containing spaces, non-printable characters, 1266 '%' or '"'. Device names in /etc/fstab and other places may need to 1267 be updated. 1268 126920121217: 1270 By default, only the 10 most recent kernel dumps will be saved. To 1271 restore the previous behaviour (no limit on the number of kernel dumps 1272 stored in the dump directory) add the following line to /etc/rc.conf: 1273 1274 savecore_flags="" 1275 127620121201: 1277 With the addition of auditdistd(8), a new auditdistd user is now 1278 required during installworld. "mergemaster -p" can be used to 1279 add the user prior to installworld, as documented in the handbook. 1280 128120121117: 1282 The sin6_scope_id member variable in struct sockaddr_in6 is now 1283 filled by the kernel before passing the structure to the userland via 1284 sysctl or routing socket. This means the KAME-specific embedded scope 1285 id in sin6_addr.s6_addr[2] is always cleared in userland application. 1286 This behavior can be controlled by net.inet6.ip6.deembed_scopeid. 1287 __FreeBSD_version is bumped to 1000025. 1288 128920121105: 1290 On i386 and amd64 systems WITH_CLANG_IS_CC is now the default. 1291 This means that the world and kernel will be compiled with clang 1292 and that clang will be installed as /usr/bin/cc, /usr/bin/c++, 1293 and /usr/bin/cpp. To disable this behavior and revert to building 1294 with gcc, compile with WITHOUT_CLANG_IS_CC. Really old versions 1295 of current may need to bootstrap WITHOUT_CLANG first if the clang 1296 build fails (its compatibility window doesn't extend to the 9 stable 1297 branch point). 1298 129920121102: 1300 The IPFIREWALL_FORWARD kernel option has been removed. Its 1301 functionality now turned on by default. 1302 130320121023: 1304 The ZERO_COPY_SOCKET kernel option has been removed and 1305 split into SOCKET_SEND_COW and SOCKET_RECV_PFLIP. 1306 NB: SOCKET_SEND_COW uses the VM page based copy-on-write 1307 mechanism which is not safe and may result in kernel crashes. 1308 NB: The SOCKET_RECV_PFLIP mechanism is useless as no current 1309 driver supports disposeable external page sized mbuf storage. 1310 Proper replacements for both zero-copy mechanisms are under 1311 consideration and will eventually lead to complete removal 1312 of the two kernel options. 1313 131420121023: 1315 The IPv4 network stack has been converted to network byte 1316 order. The following modules need to be recompiled together 1317 with kernel: carp(4), divert(4), gif(4), siftr(4), gre(4), 1318 pf(4), ipfw(4), ng_ipfw(4), stf(4). 1319 132020121022: 1321 Support for non-MPSAFE filesystems was removed from VFS. The 1322 VFS_VERSION was bumped, all filesystem modules shall be 1323 recompiled. 1324 132520121018: 1326 All the non-MPSAFE filesystems have been disconnected from 1327 the build. The full list includes: codafs, hpfs, ntfs, nwfs, 1328 portalfs, smbfs, xfs. 1329 133020121016: 1331 The interface cloning API and ABI has changed. The following 1332 modules need to be recompiled together with kernel: 1333 ipfw(4), pfsync(4), pflog(4), usb(4), wlan(4), stf(4), 1334 vlan(4), disc(4), edsc(4), if_bridge(4), gif(4), tap(4), 1335 faith(4), epair(4), enc(4), tun(4), if_lagg(4), gre(4). 1336 133720121015: 1338 The sdhci driver was split in two parts: sdhci (generic SD Host 1339 Controller logic) and sdhci_pci (actual hardware driver). 1340 No kernel config modifications are required, but if you 1341 load sdhc as a module you must switch to sdhci_pci instead. 1342 134320121014: 1344 Import the FUSE kernel and userland support into base system. 1345 134620121013: 1347 The GNU sort(1) program has been removed since the BSD-licensed 1348 sort(1) has been the default for quite some time and no serious 1349 problems have been reported. The corresponding WITH_GNU_SORT 1350 knob has also gone. 1351 135220121006: 1353 The pfil(9) API/ABI for AF_INET family has been changed. Packet 1354 filtering modules: pf(4), ipfw(4), ipfilter(4) need to be recompiled 1355 with new kernel. 1356 135720121001: 1358 The net80211(4) ABI has been changed to allow for improved driver 1359 PS-POLL and power-save support. All wireless drivers need to be 1360 recompiled to work with the new kernel. 1361 136220120913: 1363 The random(4) support for the VIA hardware random number 1364 generator (`PADLOCK') is no longer enabled unconditionally. 1365 Add the padlock_rng device in the custom kernel config if 1366 needed. The GENERIC kernels on i386 and amd64 do include the 1367 device, so the change only affects the custom kernel 1368 configurations. 1369 137020120908: 1371 The pf(4) packet filter ABI has been changed. pfctl(8) and 1372 snmp_pf module need to be recompiled to work with new kernel. 1373 137420120828: 1375 A new ZFS feature flag "com.delphix:empty_bpobj" has been merged 1376 to -HEAD. Pools that have empty_bpobj in active state can not be 1377 imported read-write with ZFS implementations that do not support 1378 this feature. For more information read the zpool-features(5) 1379 manual page. 1380 138120120727: 1382 The sparc64 ZFS loader has been changed to no longer try to auto- 1383 detect ZFS providers based on diskN aliases but now requires these 1384 to be explicitly listed in the OFW boot-device environment variable. 1385 138620120712: 1387 The OpenSSL has been upgraded to 1.0.1c. Any binaries requiring 1388 libcrypto.so.6 or libssl.so.6 must be recompiled. Also, there are 1389 configuration changes. Make sure to merge /etc/ssl/openssl.cnf. 1390 139120120712: 1392 The following sysctls and tunables have been renamed for consistency 1393 with other variables: 1394 kern.cam.da.da_send_ordered -> kern.cam.da.send_ordered 1395 kern.cam.ada.ada_send_ordered -> kern.cam.ada.send_ordered 1396 139720120628: 1398 The sort utility has been replaced with BSD sort. For now, GNU sort 1399 is also available as "gnusort" or the default can be set back to 1400 GNU sort by setting WITH_GNU_SORT. In this case, BSD sort will be 1401 installed as "bsdsort". 1402 140320120611: 1404 A new version of ZFS (pool version 5000) has been merged to -HEAD. 1405 Starting with this version the old system of ZFS pool versioning 1406 is superseded by "feature flags". This concept enables forward 1407 compatibility against certain future changes in functionality of ZFS 1408 pools. The first read-only compatible "feature flag" for ZFS pools 1409 is named "com.delphix:async_destroy". For more information 1410 read the new zpool-features(5) manual page. 1411 Please refer to the "ZFS notes" section of this file for information 1412 on upgrading boot ZFS pools. 1413 141420120417: 1415 The malloc(3) implementation embedded in libc now uses sources imported 1416 as contrib/jemalloc. The most disruptive API change is to 1417 /etc/malloc.conf. If your system has an old-style /etc/malloc.conf, 1418 delete it prior to installworld, and optionally re-create it using the 1419 new format after rebooting. See malloc.conf(5) for details 1420 (specifically the TUNING section and the "opt.*" entries in the MALLCTL 1421 NAMESPACE section). 1422 142320120328: 1424 Big-endian MIPS TARGET_ARCH values no longer end in "eb". mips64eb 1425 is now spelled mips64. mipsn32eb is now spelled mipsn32. mipseb is 1426 now spelled mips. This is to aid compatibility with third-party 1427 software that expects this naming scheme in uname(3). Little-endian 1428 settings are unchanged. If you are updating a big-endian mips64 machine 1429 from before this change, you may need to set MACHINE_ARCH=mips64 in 1430 your environment before the new build system will recognize your machine. 1431 143220120306: 1433 Disable by default the option VFS_ALLOW_NONMPSAFE for all supported 1434 platforms. 1435 143620120229: 1437 Now unix domain sockets behave "as expected" on nullfs(5). Previously 1438 nullfs(5) did not pass through all behaviours to the underlying layer, 1439 as a result if we bound to a socket on the lower layer we could connect 1440 only to the lower path; if we bound to the upper layer we could connect 1441 only to the upper path. The new behavior is one can connect to both the 1442 lower and the upper paths regardless what layer path one binds to. 1443 144420120211: 1445 The getifaddrs upgrade path broken with 20111215 has been restored. 1446 If you have upgraded in between 20111215 and 20120209 you need to 1447 recompile libc again with your kernel. You still need to recompile 1448 world to be able to configure CARP but this restriction already 1449 comes from 20111215. 1450 145120120114: 1452 The set_rcvar() function has been removed from /etc/rc.subr. All 1453 base and ports rc.d scripts have been updated, so if you have a 1454 port installed with a script in /usr/local/etc/rc.d you can either 1455 hand-edit the rcvar= line, or reinstall the port. 1456 1457 An easy way to handle the mass-update of /etc/rc.d: 1458 rm /etc/rc.d/* && mergemaster -i 1459 146020120109: 1461 panic(9) now stops other CPUs in the SMP systems, disables interrupts 1462 on the current CPU and prevents other threads from running. 1463 This behavior can be reverted using the kern.stop_scheduler_on_panic 1464 tunable/sysctl. 1465 The new behavior can be incompatible with kern.sync_on_panic. 1466 146720111215: 1468 The carp(4) facility has been changed significantly. Configuration 1469 of the CARP protocol via ifconfig(8) has changed, as well as format 1470 of CARP events submitted to devd(8) has changed. See manual pages 1471 for more information. The arpbalance feature of carp(4) is currently 1472 not supported anymore. 1473 1474 Size of struct in_aliasreq, struct in6_aliasreq has changed. User 1475 utilities using SIOCAIFADDR, SIOCAIFADDR_IN6, e.g. ifconfig(8), 1476 need to be recompiled. 1477 147820111122: 1479 The acpi_wmi(4) status device /dev/wmistat has been renamed to 1480 /dev/wmistat0. 1481 148220111108: 1483 The option VFS_ALLOW_NONMPSAFE option has been added in order to 1484 explicitely support non-MPSAFE filesystems. 1485 It is on by default for all supported platform at this present 1486 time. 1487 148820111101: 1489 The broken amd(4) driver has been replaced with esp(4) in the amd64, 1490 i386 and pc98 GENERIC kernel configuration files. 1491 149220110930: 1493 sysinstall has been removed 1494 149520110923: 1496 The stable/9 branch created in subversion. This corresponds to the 1497 RELENG_9 branch in CVS. 1498 1499COMMON ITEMS: 1500 1501 General Notes 1502 ------------- 1503 Avoid using make -j when upgrading. While generally safe, there are 1504 sometimes problems using -j to upgrade. If your upgrade fails with 1505 -j, please try again without -j. From time to time in the past there 1506 have been problems using -j with buildworld and/or installworld. This 1507 is especially true when upgrading between "distant" versions (eg one 1508 that cross a major release boundary or several minor releases, or when 1509 several months have passed on the -current branch). 1510 1511 Sometimes, obscure build problems are the result of environment 1512 poisoning. This can happen because the make utility reads its 1513 environment when searching for values for global variables. To run 1514 your build attempts in an "environmental clean room", prefix all make 1515 commands with 'env -i '. See the env(1) manual page for more details. 1516 1517 When upgrading from one major version to another it is generally best 1518 to upgrade to the latest code in the currently installed branch first, 1519 then do an upgrade to the new branch. This is the best-tested upgrade 1520 path, and has the highest probability of being successful. Please try 1521 this approach before reporting problems with a major version upgrade. 1522 1523 When upgrading a live system, having a root shell around before 1524 installing anything can help undo problems. Not having a root shell 1525 around can lead to problems if pam has changed too much from your 1526 starting point to allow continued authentication after the upgrade. 1527 1528 This file should be read as a log of events. When a later event changes 1529 information of a prior event, the prior event should not be deleted. 1530 Instead, a pointer to the entry with the new information should be 1531 placed in the old entry. Readers of this file should also sanity check 1532 older entries before relying on them blindly. Authors of new entries 1533 should write them with this in mind. 1534 1535 ZFS notes 1536 --------- 1537 When upgrading the boot ZFS pool to a new version, always follow 1538 these two steps: 1539 1540 1.) recompile and reinstall the ZFS boot loader and boot block 1541 (this is part of "make buildworld" and "make installworld") 1542 1543 2.) update the ZFS boot block on your boot drive 1544 1545 The following example updates the ZFS boot block on the first 1546 partition (freebsd-boot) of a GPT partitioned drive ada0: 1547 "gpart bootcode -p /boot/gptzfsboot -i 1 ada0" 1548 1549 Non-boot pools do not need these updates. 1550 1551 To build a kernel 1552 ----------------- 1553 If you are updating from a prior version of FreeBSD (even one just 1554 a few days old), you should follow this procedure. It is the most 1555 failsafe as it uses a /usr/obj tree with a fresh mini-buildworld, 1556 1557 make kernel-toolchain 1558 make -DALWAYS_CHECK_MAKE buildkernel KERNCONF=YOUR_KERNEL_HERE 1559 make -DALWAYS_CHECK_MAKE installkernel KERNCONF=YOUR_KERNEL_HERE 1560 1561 To test a kernel once 1562 --------------------- 1563 If you just want to boot a kernel once (because you are not sure 1564 if it works, or if you want to boot a known bad kernel to provide 1565 debugging information) run 1566 make installkernel KERNCONF=YOUR_KERNEL_HERE KODIR=/boot/testkernel 1567 nextboot -k testkernel 1568 1569 To just build a kernel when you know that it won't mess you up 1570 -------------------------------------------------------------- 1571 This assumes you are already running a CURRENT system. Replace 1572 ${arch} with the architecture of your machine (e.g. "i386", 1573 "arm", "amd64", "ia64", "pc98", "sparc64", "powerpc", "mips", etc). 1574 1575 cd src/sys/${arch}/conf 1576 config KERNEL_NAME_HERE 1577 cd ../compile/KERNEL_NAME_HERE 1578 make depend 1579 make 1580 make install 1581 1582 If this fails, go to the "To build a kernel" section. 1583 1584 To rebuild everything and install it on the current system. 1585 ----------------------------------------------------------- 1586 # Note: sometimes if you are running current you gotta do more than 1587 # is listed here if you are upgrading from a really old current. 1588 1589 <make sure you have good level 0 dumps> 1590 make buildworld 1591 make kernel KERNCONF=YOUR_KERNEL_HERE 1592 [1] 1593 <reboot in single user> [3] 1594 mergemaster -Fp [5] 1595 make installworld 1596 mergemaster -Fi [4] 1597 make delete-old [6] 1598 <reboot> 1599 1600 To cross-install current onto a separate partition 1601 -------------------------------------------------- 1602 # In this approach we use a separate partition to hold 1603 # current's root, 'usr', and 'var' directories. A partition 1604 # holding "/", "/usr" and "/var" should be about 2GB in 1605 # size. 1606 1607 <make sure you have good level 0 dumps> 1608 <boot into -stable> 1609 make buildworld 1610 make buildkernel KERNCONF=YOUR_KERNEL_HERE 1611 <maybe newfs current's root partition> 1612 <mount current's root partition on directory ${CURRENT_ROOT}> 1613 make installworld DESTDIR=${CURRENT_ROOT} -DDB_FROM_SRC 1614 make distribution DESTDIR=${CURRENT_ROOT} # if newfs'd 1615 make installkernel KERNCONF=YOUR_KERNEL_HERE DESTDIR=${CURRENT_ROOT} 1616 cp /etc/fstab ${CURRENT_ROOT}/etc/fstab # if newfs'd 1617 <edit ${CURRENT_ROOT}/etc/fstab to mount "/" from the correct partition> 1618 <reboot into current> 1619 <do a "native" rebuild/install as described in the previous section> 1620 <maybe install compatibility libraries from ports/misc/compat*> 1621 <reboot> 1622 1623 1624 To upgrade in-place from stable to current 1625 ---------------------------------------------- 1626 <make sure you have good level 0 dumps> 1627 make buildworld [9] 1628 make kernel KERNCONF=YOUR_KERNEL_HERE [8] 1629 [1] 1630 <reboot in single user> [3] 1631 mergemaster -Fp [5] 1632 make installworld 1633 mergemaster -Fi [4] 1634 make delete-old [6] 1635 <reboot> 1636 1637 Make sure that you've read the UPDATING file to understand the 1638 tweaks to various things you need. At this point in the life 1639 cycle of current, things change often and you are on your own 1640 to cope. The defaults can also change, so please read ALL of 1641 the UPDATING entries. 1642 1643 Also, if you are tracking -current, you must be subscribed to 1644 freebsd-current@freebsd.org. Make sure that before you update 1645 your sources that you have read and understood all the recent 1646 messages there. If in doubt, please track -stable which has 1647 much fewer pitfalls. 1648 1649 [1] If you have third party modules, such as vmware, you 1650 should disable them at this point so they don't crash your 1651 system on reboot. 1652 1653 [3] From the bootblocks, boot -s, and then do 1654 fsck -p 1655 mount -u / 1656 mount -a 1657 cd src 1658 adjkerntz -i # if CMOS is wall time 1659 Also, when doing a major release upgrade, it is required that 1660 you boot into single user mode to do the installworld. 1661 1662 [4] Note: This step is non-optional. Failure to do this step 1663 can result in a significant reduction in the functionality of the 1664 system. Attempting to do it by hand is not recommended and those 1665 that pursue this avenue should read this file carefully, as well 1666 as the archives of freebsd-current and freebsd-hackers mailing lists 1667 for potential gotchas. The -U option is also useful to consider. 1668 See mergemaster(8) for more information. 1669 1670 [5] Usually this step is a noop. However, from time to time 1671 you may need to do this if you get unknown user in the following 1672 step. It never hurts to do it all the time. You may need to 1673 install a new mergemaster (cd src/usr.sbin/mergemaster && make 1674 install) after the buildworld before this step if you last updated 1675 from current before 20130425 or from -stable before 20130430. 1676 1677 [6] This only deletes old files and directories. Old libraries 1678 can be deleted by "make delete-old-libs", but you have to make 1679 sure that no program is using those libraries anymore. 1680 1681 [8] In order to have a kernel that can run the 4.x binaries needed to 1682 do an installworld, you must include the COMPAT_FREEBSD4 option in 1683 your kernel. Failure to do so may leave you with a system that is 1684 hard to boot to recover. A similar kernel option COMPAT_FREEBSD5 is 1685 required to run the 5.x binaries on more recent kernels. And so on 1686 for COMPAT_FREEBSD6 and COMPAT_FREEBSD7. 1687 1688 Make sure that you merge any new devices from GENERIC since the 1689 last time you updated your kernel config file. 1690 1691 [9] When checking out sources, you must include the -P flag to have 1692 cvs prune empty directories. 1693 1694 If CPUTYPE is defined in your /etc/make.conf, make sure to use the 1695 "?=" instead of the "=" assignment operator, so that buildworld can 1696 override the CPUTYPE if it needs to. 1697 1698 MAKEOBJDIRPREFIX must be defined in an environment variable, and 1699 not on the command line, or in /etc/make.conf. buildworld will 1700 warn if it is improperly defined. 1701FORMAT: 1702 1703This file contains a list, in reverse chronological order, of major 1704breakages in tracking -current. It is not guaranteed to be a complete 1705list of such breakages, and only contains entries since September 23, 2011. 1706If you need to see UPDATING entries from before that date, you will need 1707to fetch an UPDATING file from an older FreeBSD release. 1708 1709Copyright information: 1710 1711Copyright 1998-2009 M.
