UPDATING revision 329114
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 1920180210: 20 The geli password typed at boot is now hidden. To restore the previous 21 behavior, see geli(8) for configuration options. 22 2320180113: 24 The SW_WATCHDOG option is no longer necessary to enable the 25 hardclock-based software watchdog if no hardware watchdog is 26 configured. As before, SW_WATCHDOG will cause the software 27 watchdog to be enabled even if a hardware watchdog is configured. 28 2920180108: 30 lint(1) binaries and library are no longer built by default. To 31 enable building them, define WITH_LINT in src.conf. If you are using 32 a FreeBSD 12 or later system to build 11-stable, you may need to 33 install a lint(1) binary to use WITH_LINT. 34 3520171003: 36 When building multiple kernels using KERNCONF, non-existent KERNCONF 37 files will produce an error and buildkernel will fail. Previously 38 missing KERNCONF files silently failed giving no indication as to 39 why, only to subsequently discover during installkernel that the 40 desired kernel was never built in the first place. 41 4220170926: 43 Clang, llvm, lldb, compiler-rt and libc++ have been upgraded to 5.0.0. 44 Please see the 20141231 entry below for information about prerequisites 45 and upgrading, if you are not already using clang 3.5.0 or higher. 46 4720170822: 48 Since the switch to GPT disk labels, fsck for UFS/FFS has been 49 unable to automatically find alternate superblocks. As of r322806, 50 the information needed to find alternate superblocks has been 51 moved to the end of the area reserved for the boot block. 52 Filesystems created with a newfs of this vintage or later 53 will create the recovery information. If you have a filesystem 54 created prior to this change and wish to have a recovery block 55 created for your filesystem, you can do so by running fsck in 56 forground mode (i.e., do not use the -p or -y options). As it 57 starts, fsck will ask ``SAVE DATA TO FIND ALTERNATE SUPERBLOCKS'' 58 to which you should answer yes. 59 6020170518: 61 arm64 builds now use the base system LLD 4.0.0 linker by default, 62 instead of requiring that the aarch64-binutils port or package be 63 installed. To continue using aarch64-binutils, set 64 CROSS_BINUTILS_PREFIX=/usr/local/aarch64-freebsd/bin . 65 6620170529: 67 The ctl.ko module no longer implements the iSCSI target frontend: 68 cfiscsi.ko does instead. 69 70 If building cfiscsi.ko as a kernel module, the module can be loaded 71 via one of the following methods: 72 - `cfiscsi_load="YES"` in loader.conf(5). 73 - Add `cfiscsi` to `$kld_list` in rc.conf(5). 74 - ctladm(8)/ctld(8), when compiled with iSCSI support 75 (`WITH_ISCSI=yes` in src.conf(5)) 76 77 Please see cfiscsi(4) for more details. 78 7920170511: 80 The mmcsd.ko module now additionally depends on geom_flashmap.ko. 81 Also, mmc.ko and mmcsd.ko need to be a matching pair built from the 82 same source (previously, the dependency of mmcsd.ko on mmc.ko was 83 missing, but mmcsd.ko now will refuse to load if it is incompatible 84 with mmc.ko). 85 8620170414: 87 Binds and sends to the loopback addresses, IPv6 and IPv4, will now 88 use any explicitly assigned loopback address available in the jail 89 instead of using the first assigned address of the jail. 90 9120170413: 92 As of r316810 for ipfilter, keep frags is no longer assumed when 93 keep state is specified in a rule. r316810 aligns ipfilter with 94 documentation in man pages separating keep frags from keep state. 95 This allows keep state to specified without forcing keep frags 96 and allows keep frags to be specified independently of keep state. 97 To maintain previous behaviour, also specify keep frags with 98 keep state (as documented in ipf.conf.5). 99 10020170402: 101 Clang, llvm, lldb, compiler-rt and libc++ have been upgraded to 4.0.0. 102 Please see the 20141231 entry below for information about prerequisites 103 and upgrading, if you are not already using clang 3.5.0 or higher. 104 10520170323: 106 The code that provides support for ZFS .zfs/ directory functionality 107 has been reimplemented. It's not possible now to create a snapshot 108 by mkdir under .zfs/snapshot/. That should be the only user visible 109 change. 110 11120170319: 112 Many changes in the IPsec code have been merged from the FreeBSD-CURRENT 113 branch. The IPSEC_FILTERTUNNEL kernel option is removed in favour of 114 corresponding sysctl. The IPSEC_NAT_T kernel option is also removed, 115 and now NAT-T is supported by default. Security associations now use 116 the single namespace for SPI allocation, so if you use several manually 117 configured security associations with the same SPI, this configuration 118 needs modification. 119 12020161217: 121 Clang, llvm, lldb, compiler-rt and libc++ have been upgraded to 3.9.1. 122 Please see the 20141231 entry below for information about prerequisites 123 and upgrading, if you are not already using clang 3.5.0 or higher. 124 12520161124: 126 Clang, llvm, lldb, compiler-rt and libc++ have been upgraded to 3.9.0. 127 Please see the 20141231 entry below for information about prerequisites 128 and upgrading, if you are not already using clang 3.5.0 or higher. 129 13020161119: 131 The layout of the pmap structure has changed for powerpc to put the pmap 132 statistics at the front for all CPU variations. libkvm(3) and all tools 133 that link against it need to be recompiled. 134 13520161030: 136 isl(4) and cyapa(4) drivers now require a new driver, 137 chromebook_platform(4), to work properly on Chromebook-class hardware. 138 On other types of hardware the drivers may need to be configured using 139 device hints. Please see the corresponding manual pages for details. 140 14120161210: 142 Relocatable object files with the extension of .So have been renamed 143 to use an extension of .pico instead. The purpose of this change is 144 to avoid a name clash with shared libraries on case-insensitive file 145 systems. On those file systems, foo.So is the same file as foo.so. 146 14720160622: 148 The libc stub for the pipe(2) system call has been replaced with 149 a wrapper that calls the pipe2(2) system call and the pipe(2) 150 system call is now only implemented by the kernels that include 151 "options COMPAT_FREEBSD10" in their config file (this is the 152 default). Users should ensure that this option is enabled in 153 their kernel or upgrade userspace to r302092 before upgrading their 154 kernel. 155 15620160527: 157 CAM will now strip leading spaces from SCSI disks' serial numbers. 158 This will effect users who create UFS filesystems on SCSI disks using 159 those disk's diskid device nodes. For example, if /etc/fstab 160 previously contained a line like 161 "/dev/diskid/DISK-%20%20%20%20%20%20%20ABCDEFG0123456", you should 162 change it to "/dev/diskid/DISK-ABCDEFG0123456". Users of geom 163 transforms like gmirror may also be affected. ZFS users should 164 generally be fine. 165 16620160523: 167 The bitstring(3) API has been updated with new functionality and 168 improved performance. But it is binary-incompatible with the old API. 169 Objects built with the new headers may not be linked against objects 170 built with the old headers. 171 17220160520: 173 The brk and sbrk functions have been removed from libc on arm64. 174 Binutils from ports has been updated to not link to these 175 functions and should be updated to the latest version before 176 installing a new libc. 177 17820160517: 179 The armv6 port now defaults to hard float ABI. Limited support 180 for running both hardfloat and soft float on the same system 181 is available using the libraries installed with -DWITH_LIBSOFT. 182 This has only been tested as an upgrade path for installworld 183 and packages may fail or need manual intervention to run. New 184 packages will be needed. 185 186 To update an existing self-hosted armv6hf system, you must add 187 TARGET_ARCH=armv6 on the make command line for both the build 188 and the install steps. 189 19020160510: 191 Kernel modules compiled outside of a kernel build now default to 192 installing to /boot/modules instead of /boot/kernel. Many kernel 193 modules built this way (such as those in ports) already overrode 194 KMODDIR explicitly to install into /boot/modules. However, 195 manually building and installing a module from /sys/modules will 196 now install to /boot/modules instead of /boot/kernel. 197 19820160414: 199 The CAM I/O scheduler has been committed to the kernel. There should be 200 no user visible impact. This does enable NCQ Trim on ada SSDs. While the 201 list of known rogues that claim support for this but actually corrupt 202 data is believed to be complete, be on the lookout for data 203 corruption. The known rogue list is believed to be complete: 204 205 o Crucial MX100, M550 drives with MU01 firmware. 206 o Micron M510 and M550 drives with MU01 firmware. 207 o Micron M500 prior to MU07 firmware 208 o Samsung 830, 840, and 850 all firmwares 209 o FCCT M500 all firmwares 210 211 Crucial has firmware http://www.crucial.com/usa/en/support-ssd-firmware 212 with working NCQ TRIM. For Micron branded drives, see your sales rep for 213 updated firmware. Black listed drives will work correctly because these 214 drives work correctly so long as no NCQ TRIMs are sent to them. Given 215 this list is the same as found in Linux, it's believed there are no 216 other rogues in the market place. All other models from the above 217 vendors work. 218 219 To be safe, if you are at all concerned, you can quirk each of your 220 drives to prevent NCQ from being sent by setting: 221 kern.cam.ada.X.quirks="0x2" 222 in loader.conf. If the drive requires the 4k sector quirk, set the 223 quirks entry to 0x3. 224 22520160330: 226 The FAST_DEPEND build option has been removed and its functionality is 227 now the one true way. The old mkdep(1) style of 'make depend' has 228 been removed. See 20160311 for further details. 229 23020160317: 231 Resource range types have grown from unsigned long to uintmax_t. All 232 drivers, and anything using libdevinfo, need to be recompiled. 233 23420160311: 235 WITH_FAST_DEPEND is now enabled by default for in-tree and out-of-tree 236 builds. It no longer runs mkdep(1) during 'make depend', and the 237 'make depend' stage can safely be skipped now as it is auto ran 238 when building 'make all' and will generate all SRCS and DPSRCS before 239 building anything else. Dependencies are gathered at compile time with 240 -MF flags kept in separate .depend files per object file. Users should 241 run 'make cleandepend' once if using -DNO_CLEAN to clean out older 242 stale .depend files. 243 24420160306: 245 On amd64, clang 3.8.0 can now insert sections of type AMD64_UNWIND into 246 kernel modules. Therefore, if you load any kernel modules at boot time, 247 please install the boot loaders after you install the kernel, but before 248 rebooting, e.g.: 249 250 make buildworld 251 make kernel KERNCONF=YOUR_KERNEL_HERE 252 make -C sys/boot install 253 <reboot in single user> 254 255 Then follow the usual steps, described in the General Notes section, 256 below. 257 25820160305: 259 Clang, llvm, lldb and compiler-rt have been upgraded to 3.8.0. Please 260 see the 20141231 entry below for information about prerequisites and 261 upgrading, if you are not already using clang 3.5.0 or higher. 262 26320160301: 264 The AIO subsystem is now a standard part of the kernel. The 265 VFS_AIO kernel option and aio.ko kernel module have been removed. 266 Due to stability concerns, asynchronous I/O requests are only 267 permitted on sockets and raw disks by default. To enable 268 asynchronous I/O requests on all file types, set the 269 vfs.aio.enable_unsafe sysctl to a non-zero value. 270 27120160226: 272 The ELF object manipulation tool objcopy is now provided by the 273 ELF Tool Chain project rather than by GNU binutils. It should be a 274 drop-in replacement, with the addition of arm64 support. The 275 (temporary) src.conf knob WITHOUT_ELFCOPY_AS_OBJCOPY knob may be set 276 to obtain the GNU version if necessary. 277 27820160129: 279 Building ZFS pools on top of zvols is prohibited by default. That 280 feature has never worked safely; it's always been prone to deadlocks. 281 Using a zvol as the backing store for a VM guest's virtual disk will 282 still work, even if the guest is using ZFS. Legacy behavior can be 283 restored by setting vfs.zfs.vol.recursive=1. 284 28520160119: 286 The NONE and HPN patches has been removed from OpenSSH. They are 287 still available in the security/openssh-portable port. 288 28920160113: 290 With the addition of ypldap(8), a new _ypldap user is now required 291 during installworld. "mergemaster -p" can be used to add the user 292 prior to installworld, as documented in the handbook. 293 29420151216: 295 The tftp loader (pxeboot) now uses the option root-path directive. As a 296 consequence it no longer looks for a pxeboot.4th file on the tftp 297 server. Instead it uses the regular /boot infrastructure as with the 298 other loaders. 299 30020151211: 301 The code to start recording plug and play data into the modules has 302 been committed. While the old tools will properly build a new kernel, 303 a number of warnings about "unknown metadata record 4" will be produced 304 for an older kldxref. To avoid such warnings, make sure to rebuild 305 the kernel toolchain (or world). Make sure that you have r292078 or 306 later when trying to build 292077 or later before rebuilding. 307 30820151207: 309 Debug data files are now built by default with 'make buildworld' and 310 installed with 'make installworld'. This facilitates debugging but 311 requires more disk space both during the build and for the installed 312 world. Debug files may be disabled by setting WITHOUT_DEBUG_FILES=yes 313 in src.conf(5). 314 31520151130: 316 r291527 changed the internal interface between the nfsd.ko and 317 nfscommon.ko modules. As such, they must both be upgraded to-gether. 318 __FreeBSD_version has been bumped because of this. 319 32020151108: 321 Add support for unicode collation strings leads to a change of 322 order of files listed by ls(1) for example. To get back to the old 323 behaviour, set LC_COLLATE environment variable to "C". 324 325 Databases administrators will need to reindex their databases given 326 collation results will be different. 327 328 Due to a bug in install(1) it is recommended to remove the ancient 329 locales before running make installworld. 330 331 rm -rf /usr/share/locale/* 332 33320151030: 334 The OpenSSL has been upgraded to 1.0.2d. Any binaries requiring 335 libcrypto.so.7 or libssl.so.7 must be recompiled. 336 33720151020: 338 Qlogic 24xx/25xx firmware images were updated from 5.5.0 to 7.3.0. 339 Kernel modules isp_2400_multi and isp_2500_multi were removed and 340 should be replaced with isp_2400 and isp_2500 modules respectively. 341 34220151017: 343 The build previously allowed using 'make -n' to not recurse into 344 sub-directories while showing what commands would be executed, and 345 'make -n -n' to recursively show commands. Now 'make -n' will recurse 346 and 'make -N' will not. 347 34820151012: 349 If you specify SENDMAIL_MC or SENDMAIL_CF in make.conf, mergemaster 350 and etcupdate will now use this file. A custom sendmail.cf is now 351 updated via this mechanism rather than via installworld. If you had 352 excluded sendmail.cf in mergemaster.rc or etcupdate.conf, you may 353 want to remove the exclusion or change it to "always install". 354 /etc/mail/sendmail.cf is now managed the same way regardless of 355 whether SENDMAIL_MC/SENDMAIL_CF is used. If you are not using 356 SENDMAIL_MC/SENDMAIL_CF there should be no change in behavior. 357 35820151011: 359 Compatibility shims for legacy ATA device names have been removed. 360 It includes ATA_STATIC_ID kernel option, kern.cam.ada.legacy_aliases 361 and kern.geom.raid.legacy_aliases loader tunables, kern.devalias.* 362 environment variables, /dev/ad* and /dev/ar* symbolic links. 363 36420151006: 365 Clang, llvm, lldb, compiler-rt and libc++ have been upgraded to 3.7.0. 366 Please see the 20141231 entry below for information about prerequisites 367 and upgrading, if you are not already using clang 3.5.0 or higher. 368 36920150924: 370 Kernel debug files have been moved to /usr/lib/debug/boot/kernel/, 371 and renamed from .symbols to .debug. This reduces the size requirements 372 on the boot partition or file system and provides consistency with 373 userland debug files. 374 375 When using the supported kernel installation method the 376 /usr/lib/debug/boot/kernel directory will be renamed (to kernel.old) 377 as is done with /boot/kernel. 378 379 Developers wishing to maintain the historical behavior of installing 380 debug files in /boot/kernel/ can set KERN_DEBUGDIR="" in src.conf(5). 381 38220150827: 383 The wireless drivers had undergone changes that remove the 'parent 384 interface' from the ifconfig -l output. The rc.d network scripts 385 used to check presence of a parent interface in the list, so old 386 scripts would fail to start wireless networking. Thus, etcupdate(3) 387 or mergemaster(8) run is required after kernel update, to update your 388 rc.d scripts in /etc. 389 39020150827: 391 pf no longer supports 'scrub fragment crop' or 'scrub fragment drop-ovl' 392 These configurations are now automatically interpreted as 393 'scrub fragment reassemble'. 394 39520150817: 396 Kernel-loadable modules for the random(4) device are back. To use 397 them, the kernel must have 398 399 device random 400 options RANDOM_LOADABLE 401 402 kldload(8) can then be used to load random_fortuna.ko 403 or random_yarrow.ko. Please note that due to the indirect 404 function calls that the loadable modules need to provide, 405 the build-in variants will be slightly more efficient. 406 407 The random(4) kernel option RANDOM_DUMMY has been retired due to 408 unpopularity. It was not all that useful anyway. 409 41020150813: 411 The WITHOUT_ELFTOOLCHAIN_TOOLS src.conf(5) knob has been retired. 412 Control over building the ELF Tool Chain tools is now provided by 413 the WITHOUT_TOOLCHAIN knob. 414 41520150810: 416 The polarity of Pulse Per Second (PPS) capture events with the 417 uart(4) driver has been corrected. Prior to this change the PPS 418 "assert" event corresponded to the trailing edge of a positive PPS 419 pulse and the "clear" event was the leading edge of the next pulse. 420 421 As the width of a PPS pulse in a typical GPS receiver is on the 422 order of 1 millisecond, most users will not notice any significant 423 difference with this change. 424 425 Anyone who has compensated for the historical polarity reversal by 426 configuring a negative offset equal to the pulse width will need to 427 remove that workaround. 428 42920150809: 430 The default group assigned to /dev/dri entries has been changed 431 from 'wheel' to 'video' with the id of '44'. If you want to have 432 access to the dri devices please add yourself to the video group 433 with: 434 435 # pw groupmod video -m $USER 436 43720150806: 438 The menu.rc and loader.rc files will now be replaced during 439 upgrades. Please migrate local changes to menu.rc.local and 440 loader.rc.local instead. 441 44220150805: 443 GNU Binutils versions of addr2line, c++filt, nm, readelf, size, 444 strings and strip have been removed. The src.conf(5) knob 445 WITHOUT_ELFTOOLCHAIN_TOOLS no longer provides the binutils tools. 446 44720150728: 448 As ZFS requires more kernel stack pages than is the default on some 449 architectures e.g. i386, it now warns if KSTACK_PAGES is less than 450 ZFS_MIN_KSTACK_PAGES (which is 4 at the time of writing). 451 452 Please consider using 'options KSTACK_PAGES=X' where X is greater 453 than or equal to ZFS_MIN_KSTACK_PAGES i.e. 4 in such configurations. 454 45520150706: 456 sendmail has been updated to 8.15.2. Starting with FreeBSD 11.0 457 and sendmail 8.15, sendmail uses uncompressed IPv6 addresses by 458 default, i.e., they will not contain "::". For example, instead 459 of ::1, it will be 0:0:0:0:0:0:0:1. This permits a zero subnet 460 to have a more specific match, such as different map entries for 461 IPv6:0:0 vs IPv6:0. This change requires that configuration 462 data (including maps, files, classes, custom ruleset, etc.) must 463 use the same format, so make certain such configuration data is 464 upgrading. As a very simple check search for patterns like 465 'IPv6:[0-9a-fA-F:]*::' and 'IPv6::'. To return to the old 466 behavior, set the m4 option confUSE_COMPRESSED_IPV6_ADDRESSES or 467 the cf option UseCompressedIPv6Addresses. 468 46920150630: 470 The default kernel entropy-processing algorithm is now 471 Fortuna, replacing Yarrow. 472 473 Assuming you have 'device random' in your kernel config 474 file, the configurations allow a kernel option to override 475 this default. You may choose *ONE* of: 476 477 options RANDOM_YARROW # Legacy /dev/random algorithm. 478 options RANDOM_DUMMY # Blocking-only driver. 479 480 If you have neither, you get Fortuna. For most people, 481 read no further, Fortuna will give a /dev/random that works 482 like it always used to, and the difference will be irrelevant. 483 484 If you remove 'device random', you get *NO* kernel-processed 485 entropy at all. This may be acceptable to folks building 486 embedded systems, but has complications. Carry on reading, 487 and it is assumed you know what you need. 488 489 *PLEASE* read random(4) and random(9) if you are in the 490 habit of tweaking kernel configs, and/or if you are a member 491 of the embedded community, wanting specific and not-usual 492 behaviour from your security subsystems. 493 494 NOTE!! If you use RANDOM_DUMMY and/or have no 'device 495 random', you will NOT have a functioning /dev/random, and 496 many cryptographic features will not work, including SSH. 497 You may also find strange behaviour from the random(3) set 498 of library functions, in particular sranddev(3), srandomdev(3) 499 and arc4random(3). The reason for this is that the KERN_ARND 500 sysctl only returns entropy if it thinks it has some to 501 share, and with RANDOM_DUMMY or no 'device random' this 502 will never happen. 503 50420150623: 505 An additional fix for the issue described in the 20150614 sendmail 506 entry below has been been committed in revision 284717. 507 50820150616: 509 FreeBSD's old make (fmake) has been removed from the system. It is 510 available as the devel/fmake port or via pkg install fmake. 511 51220150615: 513 The fix for the issue described in the 20150614 sendmail entry 514 below has been been committed in revision 284436. The work 515 around described in that entry is no longer needed unless the 516 default setting is overridden by a confDH_PARAMETERS configuration 517 setting of '5' or pointing to a 512 bit DH parameter file. 518 51920150614: 520 ALLOW_DEPRECATED_ATF_TOOLS/ATFFILE support has been removed from 521 atf.test.mk (included from bsd.test.mk). Please upgrade devel/atf 522 and devel/kyua to version 0.20+ and adjust any calling code to work 523 with Kyuafile and kyua. 524 52520150614: 526 The import of openssl to address the FreeBSD-SA-15:10.openssl 527 security advisory includes a change which rejects handshakes 528 with DH parameters below 768 bits. sendmail releases prior 529 to 8.15.2 (not yet released), defaulted to a 512 bit 530 DH parameter setting for client connections. To work around 531 this interoperability, sendmail can be configured to use a 532 2048 bit DH parameter by: 533 534 1. Edit /etc/mail/`hostname`.mc 535 2. If a setting for confDH_PARAMETERS does not exist or 536 exists and is set to a string beginning with '5', 537 replace it with '2'. 538 3. If a setting for confDH_PARAMETERS exists and is set to 539 a file path, create a new file with: 540 openssl dhparam -out /path/to/file 2048 541 4. Rebuild the .cf file: 542 cd /etc/mail/; make; make install 543 5. Restart sendmail: 544 cd /etc/mail/; make restart 545 546 A sendmail patch is coming, at which time this file will be 547 updated. 548 54920150604: 550 Generation of legacy formatted entries have been disabled by default 551 in pwd_mkdb(8), as all base system consumers of the legacy formatted 552 entries were converted to use the new format by default when the new, 553 machine independent format have been added and supported since FreeBSD 554 5.x. 555 556 Please see the pwd_mkdb(8) manual page for further details. 557 55820150525: 559 Clang and llvm have been upgraded to 3.6.1 release. Please see the 560 20141231 entry below for information about prerequisites and upgrading, 561 if you are not already using 3.5.0 or higher. 562 56320150521: 564 TI platform code switched to using vendor DTS files and this update 565 may break existing systems running on Beaglebone, Beaglebone Black, 566 and Pandaboard: 567 568 - dtb files should be regenerated/reinstalled. Filenames are the 569 same but content is different now 570 - GPIO addressing was changed, now each GPIO bank (32 pins per bank) 571 has its own /dev/gpiocX device, e.g. pin 121 on /dev/gpioc0 in old 572 addressing scheme is now pin 25 on /dev/gpioc3. 573 - Pandaboard: /etc/ttys should be updated, serial console device is 574 now /dev/ttyu2, not /dev/ttyu0 575 57620150501: 577 soelim(1) from gnu/usr.bin/groff has been replaced by usr.bin/soelim. 578 If you need the GNU extension from groff soelim(1), install groff 579 from package: pkg install groff, or via ports: textproc/groff. 580 58120150423: 582 chmod, chflags, chown and chgrp now affect symlinks in -R mode as 583 defined in symlink(7); previously symlinks were silently ignored. 584 58520150415: 586 The const qualifier has been removed from iconv(3) to comply with 587 POSIX. The ports tree is aware of this from r384038 onwards. 588 58920150416: 590 Libraries specified by LIBADD in Makefiles must have a corresponding 591 DPADD_<lib> variable to ensure correct dependencies. This is now 592 enforced in src.libnames.mk. 593 59420150324: 595 From legacy ata(4) driver was removed support for SATA controllers 596 supported by more functional drivers ahci(4), siis(4) and mvs(4). 597 Kernel modules ataahci and ataadaptec were removed completely, 598 replaced by ahci and mvs modules respectively. 599 60020150315: 601 Clang, llvm and lldb have been upgraded to 3.6.0 release. Please see 602 the 20141231 entry below for information about prerequisites and 603 upgrading, if you are not already using 3.5.0 or higher. 604 60520150307: 606 The 32-bit PowerPC kernel has been changed to a position-independent 607 executable. This can only be booted with a version of loader(8) 608 newer than January 31, 2015, so make sure to update both world and 609 kernel before rebooting. 610 61120150217: 612 If you are running a -CURRENT kernel since r273872 (Oct 30th, 2014), 613 but before r278950, the RNG was not seeded properly. Immediately 614 upgrade the kernel to r278950 or later and regenerate any keys (e.g. 615 ssh keys or openssl keys) that were generated w/ a kernel from that 616 range. This does not affect programs that directly used /dev/random 617 or /dev/urandom. All userland uses of arc4random(3) are affected. 618 61920150210: 620 The autofs(4) ABI was changed in order to restore binary compatibility 621 with 10.1-RELEASE. The automountd(8) daemon needs to be rebuilt to work 622 with the new kernel. 623 62420150131: 625 The powerpc64 kernel has been changed to a position-independent 626 executable. This can only be booted with a new version of loader(8), 627 so make sure to update both world and kernel before rebooting. 628 62920150118: 630 Clang and llvm have been upgraded to 3.5.1 release. This is a bugfix 631 only release, no new features have been added. Please see the 20141231 632 entry below for information about prerequisites and upgrading, if you 633 are not already using 3.5.0. 634 63520150107: 636 ELF tools addr2line, elfcopy (strip), nm, size, and strings are now 637 taken from the ELF Tool Chain project rather than GNU binutils. They 638 should be drop-in replacements, with the addition of arm64 support. 639 The WITHOUT_ELFTOOLCHAIN_TOOLS= knob may be used to obtain the 640 binutils tools, if necessary. See 20150805 for updated information. 641 64220150105: 643 The default Unbound configuration now enables remote control 644 using a local socket. Users who have already enabled the 645 local_unbound service should regenerate their configuration 646 by running "service local_unbound setup" as root. 647 64820150102: 649 The GNU texinfo and GNU info pages have been removed. 650 To be able to view GNU info pages please install texinfo from ports. 651 65220141231: 653 Clang, llvm and lldb have been upgraded to 3.5.0 release. 654 655 As of this release, a prerequisite for building clang, llvm and lldb is 656 a C++11 capable compiler and C++11 standard library. This means that to 657 be able to successfully build the cross-tools stage of buildworld, with 658 clang as the bootstrap compiler, your system compiler or cross compiler 659 should either be clang 3.3 or later, or gcc 4.8 or later, and your 660 system C++ library should be libc++, or libdstdc++ from gcc 4.8 or 661 later. 662 663 On any standard FreeBSD 10.x or 11.x installation, where clang and 664 libc++ are on by default (that is, on x86 or arm), this should work out 665 of the box. 666 667 On 9.x installations where clang is enabled by default, e.g. on x86 and 668 powerpc, libc++ will not be enabled by default, so libc++ should be 669 built (with clang) and installed first. If both clang and libc++ are 670 missing, build clang first, then use it to build libc++. 671 672 On 8.x and earlier installations, upgrade to 9.x first, and then follow 673 the instructions for 9.x above. 674 675 Sparc64 and mips users are unaffected, as they still use gcc 4.2.1 by 676 default, and do not build clang. 677 678 Many embedded systems are resource constrained, and will not be able to 679 build clang in a reasonable time, or in some cases at all. In those 680 cases, cross building bootable systems on amd64 is a workaround. 681 682 This new version of clang introduces a number of new warnings, of which 683 the following are most likely to appear: 684 685 -Wabsolute-value 686 687 This warns in two cases, for both C and C++: 688 * When the code is trying to take the absolute value of an unsigned 689 quantity, which is effectively a no-op, and almost never what was 690 intended. The code should be fixed, if at all possible. If you are 691 sure that the unsigned quantity can be safely cast to signed, without 692 loss of information or undefined behavior, you can add an explicit 693 cast, or disable the warning. 694 695 * When the code is trying to take an absolute value, but the called 696 abs() variant is for the wrong type, which can lead to truncation. 697 If you want to disable the warning instead of fixing the code, please 698 make sure that truncation will not occur, or it might lead to unwanted 699 side-effects. 700 701 -Wtautological-undefined-compare and 702 -Wundefined-bool-conversion 703 704 These warn when C++ code is trying to compare 'this' against NULL, while 705 'this' should never be NULL in well-defined C++ code. However, there is 706 some legacy (pre C++11) code out there, which actively abuses this 707 feature, which was less strictly defined in previous C++ versions. 708 709 Squid and openjdk do this, for example. The warning can be turned off 710 for C++98 and earlier, but compiling the code in C++11 mode might result 711 in unexpected behavior; for example, the parts of the program that are 712 unreachable could be optimized away. 713 71420141222: 715 The old NFS client and server (kernel options NFSCLIENT, NFSSERVER) 716 kernel sources have been removed. The .h files remain, since some 717 utilities include them. This will need to be fixed later. 718 If "mount -t oldnfs ..." is attempted, it will fail. 719 If the "-o" option on mountd(8), nfsd(8) or nfsstat(1) is used, 720 the utilities will report errors. 721 72220141121: 723 The handling of LOCAL_LIB_DIRS has been altered to skip addition of 724 directories to top level SUBDIR variable when their parent 725 directory is included in LOCAL_DIRS. Users with build systems with 726 such hierarchies and without SUBDIR entries in the parent 727 directory Makefiles should add them or add the directories to 728 LOCAL_DIRS. 729 73020141109: 731 faith(4) and faithd(8) have been removed from the base system. Faith 732 has been obsolete for a very long time. 733 73420141104: 735 vt(4), the new console driver, is enabled by default. It brings 736 support for Unicode and double-width characters, as well as 737 support for UEFI and integration with the KMS kernel video 738 drivers. 739 740 You may need to update your console settings in /etc/rc.conf, 741 most probably the keymap. During boot, /etc/rc.d/syscons will 742 indicate what you need to do. 743 744 vt(4) still has issues and lacks some features compared to 745 syscons(4). See the wiki for up-to-date information: 746 https://wiki.freebsd.org/Newcons 747 748 If you want to keep using syscons(4), you can do so by adding 749 the following line to /boot/loader.conf: 750 kern.vty=sc 751 75220141102: 753 pjdfstest has been integrated into kyua as an opt-in test suite. 754 Please see share/doc/pjdfstest/README for more details on how to 755 execute it. 756 75720141009: 758 gperf has been removed from the base system for architectures 759 that use clang. Ports that require gperf will obtain it from the 760 devel/gperf port. 761 76220140923: 763 pjdfstest has been moved from tools/regression/pjdfstest to 764 contrib/pjdfstest . 765 76620140922: 767 At svn r271982, The default linux compat kernel ABI has been adjusted 768 to 2.6.18 in support of the linux-c6 compat ports infrastructure 769 update. If you wish to continue using the linux-f10 compat ports, 770 add compat.linux.osrelease=2.6.16 to your local sysctl.conf. Users are 771 encouraged to update their linux-compat packages to linux-c6 during 772 their next update cycle. 773 77420140729: 775 The ofwfb driver, used to provide a graphics console on PowerPC when 776 using vt(4), no longer allows mmap() of all physical memory. This 777 will prevent Xorg on PowerPC with some ATI graphics cards from 778 initializing properly unless x11-servers/xorg-server is updated to 779 1.12.4_8 or newer. 780 78120140723: 782 The xdev targets have been converted to using TARGET and 783 TARGET_ARCH instead of XDEV and XDEV_ARCH. 784 78520140719: 786 The default unbound configuration has been modified to address 787 issues with reverse lookups on networks that use private 788 address ranges. If you use the local_unbound service, run 789 "service local_unbound setup" as root to regenerate your 790 configuration, then "service local_unbound reload" to load the 791 new configuration. 792 79320140709: 794 The GNU texinfo and GNU info pages are not built and installed 795 anymore, WITH_INFO knob has been added to allow to built and install 796 them again. 797 UPDATE: see 20150102 entry on texinfo's removal 798 79920140708: 800 The GNU readline library is now an INTERNALLIB - that is, it is 801 statically linked into consumers (GDB and variants) in the base 802 system, and the shared library is no longer installed. The 803 devel/readline port is available for third party software that 804 requires readline. 805 80620140702: 807 The Itanium architecture (ia64) has been removed from the list of 808 known architectures. This is the first step in the removal of the 809 architecture. 810 81120140701: 812 Commit r268115 has added NFSv4.1 server support, merged from 813 projects/nfsv4.1-server. Since this includes changes to the 814 internal interfaces between the NFS related modules, a full 815 build of the kernel and modules will be necessary. 816 __FreeBSD_version has been bumped. 817 81820140629: 819 The WITHOUT_VT_SUPPORT kernel config knob has been renamed 820 WITHOUT_VT. (The other _SUPPORT knobs have a consistent meaning 821 which differs from the behaviour controlled by this knob.) 822 82320140619: 824 Maximal length of the serial number in CTL was increased from 16 to 825 64 chars, that breaks ABI. All CTL-related tools, such as ctladm 826 and ctld, need to be rebuilt to work with a new kernel. 827 82820140606: 829 The libatf-c and libatf-c++ major versions were downgraded to 0 and 830 1 respectively to match the upstream numbers. They were out of 831 sync because, when they were originally added to FreeBSD, the 832 upstream versions were not respected. These libraries are private 833 and not yet built by default, so renumbering them should be a 834 non-issue. However, unclean source trees will yield broken test 835 programs once the operator executes "make delete-old-libs" after a 836 "make installworld". 837 838 Additionally, the atf-sh binary was made private by moving it into 839 /usr/libexec/. Already-built shell test programs will keep the 840 path to the old binary so they will break after "make delete-old" 841 is run. 842 843 If you are using WITH_TESTS=yes (not the default), wipe the object 844 tree and rebuild from scratch to prevent spurious test failures. 845 This is only needed once: the misnumbered libraries and misplaced 846 binaries have been added to OptionalObsoleteFiles.inc so they will 847 be removed during a clean upgrade. 848 84920140512: 850 Clang and llvm have been upgraded to 3.4.1 release. 851 85220140508: 853 We bogusly installed src.opts.mk in /usr/share/mk. This file should 854 be removed to avoid issues in the future (and has been added to 855 ObsoleteFiles.inc). 856 85720140505: 858 /etc/src.conf now affects only builds of the FreeBSD src tree. In the 859 past, it affected all builds that used the bsd.*.mk files. The old 860 behavior was a bug, but people may have relied upon it. To get this 861 behavior back, you can .include /etc/src.conf from /etc/make.conf 862 (which is still global and isn't changed). This also changes the 863 behavior of incremental builds inside the tree of individual 864 directories. Set MAKESYSPATH to ".../share/mk" to do that. 865 Although this has survived make universe and some upgrade scenarios, 866 other upgrade scenarios may have broken. At least one form of 867 temporary breakage was fixed with MAKESYSPATH settings for buildworld 868 as well... In cases where MAKESYSPATH isn't working with this 869 setting, you'll need to set it to the full path to your tree. 870 871 One side effect of all this cleaning up is that bsd.compiler.mk 872 is no longer implicitly included by bsd.own.mk. If you wish to 873 use COMPILER_TYPE, you must now explicitly include bsd.compiler.mk 874 as well. 875 87620140430: 877 The lindev device has been removed since /dev/full has been made a 878 standard device. __FreeBSD_version has been bumped. 879 88020140424: 881 The knob WITHOUT_VI was added to the base system, which controls 882 building ex(1), vi(1), etc. Older releases of FreeBSD required ex(1) 883 in order to reorder files share/termcap and didn't build ex(1) as a 884 build tool, so building/installing with WITH_VI is highly advised for 885 build hosts for older releases. 886 887 This issue has been fixed in stable/9 and stable/10 in r277022 and 888 r276991, respectively. 889 89020140418: 891 The YES_HESIOD knob has been removed. It has been obsolete for 892 a decade. Please move to using WITH_HESIOD instead or your builds 893 will silently lack HESIOD. 894 89520140405: 896 The uart(4) driver has been changed with respect to its handling 897 of the low-level console. Previously the uart(4) driver prevented 898 any process from changing the baudrate or the CLOCAL and HUPCL 899 control flags. By removing the restrictions, operators can make 900 changes to the serial console port without having to reboot. 901 However, when getty(8) is started on the serial device that is 902 associated with the low-level console, a misconfigured terminal 903 line in /etc/ttys will now have a real impact. 904 Before upgrading the kernel, make sure that /etc/ttys has the 905 serial console device configured as 3wire without baudrate to 906 preserve the previous behaviour. E.g: 907 ttyu0 "/usr/libexec/getty 3wire" vt100 on secure 908 90920140306: 910 Support for libwrap (TCP wrappers) in rpcbind was disabled by default 911 to improve performance. To re-enable it, if needed, run rpcbind 912 with command line option -W. 913 91420140226: 915 Switched back to the GPL dtc compiler due to updates in the upstream 916 dts files not being supported by the BSDL dtc compiler. You will need 917 to rebuild your kernel toolchain to pick up the new compiler. Core dumps 918 may result while building dtb files during a kernel build if you fail 919 to do so. Set WITHOUT_GPL_DTC if you require the BSDL compiler. 920 92120140216: 922 Clang and llvm have been upgraded to 3.4 release. 923 92420140216: 925 The nve(4) driver has been removed. Please use the nfe(4) driver 926 for NVIDIA nForce MCP Ethernet adapters instead. 927 92820140212: 929 An ABI incompatibility crept into the libc++ 3.4 import in r261283. 930 This could cause certain C++ applications using shared libraries built 931 against the previous version of libc++ to crash. The incompatibility 932 has now been fixed, but any C++ applications or shared libraries built 933 between r261283 and r261801 should be recompiled. 934 93520140204: 936 OpenSSH will now ignore errors caused by kernel lacking of Capsicum 937 capability mode support. Please note that enabling the feature in 938 kernel is still highly recommended. 939 94020140131: 941 OpenSSH is now built with sandbox support, and will use sandbox as 942 the default privilege separation method. This requires Capsicum 943 capability mode support in kernel. 944 94520140128: 946 The libelf and libdwarf libraries have been updated to newer 947 versions from upstream. Shared library version numbers for 948 these two libraries were bumped. Any ports or binaries 949 requiring these two libraries should be recompiled. 950 __FreeBSD_version is bumped to 1100006. 951 95220140110: 953 If a Makefile in a tests/ directory was auto-generating a Kyuafile 954 instead of providing an explicit one, this would prevent such 955 Makefile from providing its own Kyuafile in the future during 956 NO_CLEAN builds. This has been fixed in the Makefiles but manual 957 intervention is needed to clean an objdir if you use NO_CLEAN: 958 # find /usr/obj -name Kyuafile | xargs rm -f 959 96020131213: 961 The behavior of gss_pseudo_random() for the krb5 mechanism 962 has changed, for applications requesting a longer random string 963 than produced by the underlying enctype's pseudo-random() function. 964 In particular, the random string produced from a session key of 965 enctype aes256-cts-hmac-sha1-96 or aes256-cts-hmac-sha1-96 will 966 be different at the 17th octet and later, after this change. 967 The counter used in the PRF+ construction is now encoded as a 968 big-endian integer in accordance with RFC 4402. 969 __FreeBSD_version is bumped to 1100004. 970 97120131108: 972 The WITHOUT_ATF build knob has been removed and its functionality 973 has been subsumed into the more generic WITHOUT_TESTS. If you were 974 using the former to disable the build of the ATF libraries, you 975 should change your settings to use the latter. 976 97720131025: 978 The default version of mtree is nmtree which is obtained from 979 NetBSD. The output is generally the same, but may vary 980 slightly. If you found you need identical output adding 981 "-F freebsd9" to the command line should do the trick. For the 982 time being, the old mtree is available as fmtree. 983 98420131014: 985 libbsdyml has been renamed to libyaml and moved to /usr/lib/private. 986 This will break ports-mgmt/pkg. Rebuild the port, or upgrade to pkg 987 1.1.4_8 and verify bsdyml not linked in, before running "make 988 delete-old-libs": 989 # make -C /usr/ports/ports-mgmt/pkg build deinstall install clean 990 or 991 # pkg install pkg; ldd /usr/local/sbin/pkg | grep bsdyml 992 99320131010: 994 The stable/10 branch has been created in subversion from head 995 revision r256279. 996 99720131010: 998 The rc.d/jail script has been updated to support jail(8) 999 configuration file. The "jail_<jname>_*" rc.conf(5) variables 1000 for per-jail configuration are automatically converted to 1001 /var/run/jail.<jname>.conf before the jail(8) utility is invoked. 1002 This is transparently backward compatible. See below about some 1003 incompatibilities and rc.conf(5) manual page for more details. 1004 1005 These variables are now deprecated in favor of jail(8) configuration 1006 file. One can use "rc.d/jail config <jname>" command to generate 1007 a jail(8) configuration file in /var/run/jail.<jname>.conf without 1008 running the jail(8) utility. The default pathname of the 1009 configuration file is /etc/jail.conf and can be specified by 1010 using $jail_conf or $jail_<jname>_conf variables. 1011 1012 Please note that jail_devfs_ruleset accepts an integer at 1013 this moment. Please consider to rewrite the ruleset name 1014 with an integer. 1015 101620130930: 1017 BIND has been removed from the base system. If all you need 1018 is a local resolver, simply enable and start the local_unbound 1019 service instead. Otherwise, several versions of BIND are 1020 available in the ports tree. The dns/bind99 port is one example. 1021 1022 With this change, nslookup(1) and dig(1) are no longer in the base 1023 system. Users should instead use host(1) and drill(1) which are 1024 in the base system. Alternatively, nslookup and dig can 1025 be obtained by installing the dns/bind-tools port. 1026 102720130916: 1028 With the addition of unbound(8), a new unbound user is now 1029 required during installworld. "mergemaster -p" can be used to 1030 add the user prior to installworld, as documented in the handbook. 1031 103220130911: 1033 OpenSSH is now built with DNSSEC support, and will by default 1034 silently trust signed SSHFP records. This can be controlled with 1035 the VerifyHostKeyDNS client configuration setting. DNSSEC support 1036 can be disabled entirely with the WITHOUT_LDNS option in src.conf. 1037 103820130906: 1039 The GNU Compiler Collection and C++ standard library (libstdc++) 1040 are no longer built by default on platforms where clang is the system 1041 compiler. You can enable them with the WITH_GCC and WITH_GNUCXX 1042 options in src.conf. 1043 104420130905: 1045 The PROCDESC kernel option is now part of the GENERIC kernel 1046 configuration and is required for the rwhod(8) to work. 1047 If you are using custom kernel configuration, you should include 1048 'options PROCDESC'. 1049 105020130905: 1051 The API and ABI related to the Capsicum framework was modified 1052 in backward incompatible way. The userland libraries and programs 1053 have to be recompiled to work with the new kernel. This includes the 1054 following libraries and programs, but the whole buildworld is 1055 advised: libc, libprocstat, dhclient, tcpdump, hastd, hastctl, 1056 kdump, procstat, rwho, rwhod, uniq. 1057 105820130903: 1059 AES-NI intrinsic support has been added to gcc. The AES-NI module 1060 has been updated to use this support. A new gcc is required to build 1061 the aesni module on both i386 and amd64. 1062 106320130821: 1064 The PADLOCK_RNG and RDRAND_RNG kernel options are now devices. 1065 Thus "device padlock_rng" and "device rdrand_rng" should be 1066 used instead of "options PADLOCK_RNG" & "options RDRAND_RNG". 1067 106820130813: 1069 WITH_ICONV has been split into two feature sets. WITH_ICONV now 1070 enables just the iconv* functionality and is now on by default. 1071 WITH_LIBICONV_COMPAT enables the libiconv api and link time 1072 compatibility. Set WITHOUT_ICONV to build the old way. 1073 If you have been using WITH_ICONV before, you will very likely 1074 need to turn on WITH_LIBICONV_COMPAT. 1075 107620130806: 1077 INVARIANTS option now enables DEBUG for code with OpenSolaris and 1078 Illumos origin, including ZFS. If you have INVARIANTS in your 1079 kernel configuration, then there is no need to set DEBUG or ZFS_DEBUG 1080 explicitly. 1081 DEBUG used to enable witness(9) tracking of OpenSolaris (mostly ZFS) 1082 locks if WITNESS option was set. Because that generated a lot of 1083 witness(9) reports and all of them were believed to be false 1084 positives, this is no longer done. New option OPENSOLARIS_WITNESS 1085 can be used to achieve the previous behavior. 1086 108720130806: 1088 Timer values in IPv6 data structures now use time_uptime instead 1089 of time_second. Although this is not a user-visible functional 1090 change, userland utilities which directly use them---ndp(8), 1091 rtadvd(8), and rtsold(8) in the base system---need to be updated 1092 to r253970 or later. 1093 109420130802: 1095 find -delete can now delete the pathnames given as arguments, 1096 instead of only files found below them or if the pathname did 1097 not contain any slashes. Formerly, the following error message 1098 would result: 1099 1100 find: -delete: <path>: relative path potentially not safe 1101 1102 Deleting the pathnames given as arguments can be prevented 1103 without error messages using -mindepth 1 or by changing 1104 directory and passing "." as argument to find. This works in the 1105 old as well as the new version of find. 1106 110720130726: 1108 Behavior of devfs rules path matching has been changed. 1109 Pattern is now always matched against fully qualified devfs 1110 path and slash characters must be explicitly matched by 1111 slashes in pattern (FNM_PATHNAME). Rulesets involving devfs 1112 subdirectories must be reviewed. 1113 111420130716: 1115 The default ARM ABI has changed to the ARM EABI. The old ABI is 1116 incompatible with the ARM EABI and all programs and modules will 1117 need to be rebuilt to work with a new kernel. 1118 1119 To keep using the old ABI ensure the WITHOUT_ARM_EABI knob is set. 1120 1121 NOTE: Support for the old ABI will be removed in the future and 1122 users are advised to upgrade. 1123 112420130709: 1125 pkg_install has been disconnected from the build if you really need it 1126 you should add WITH_PKGTOOLS in your src.conf(5). 1127 112820130709: 1129 Most of network statistics structures were changed to be able 1130 keep 64-bits counters. Thus all tools, that work with networking 1131 statistics, must be rebuilt (netstat(1), bsnmpd(1), etc.) 1132 113320130618: 1134 Fix a bug that allowed a tracing process (e.g. gdb) to write 1135 to a memory-mapped file in the traced process's address space 1136 even if neither the traced process nor the tracing process had 1137 write access to that file. 1138 113920130615: 1140 CVS has been removed from the base system. An exact copy 1141 of the code is available from the devel/cvs port. 1142 114320130613: 1144 Some people report the following error after the switch to bmake: 1145 1146 make: illegal option -- J 1147 usage: make [-BPSXeiknpqrstv] [-C directory] [-D variable] 1148 ... 1149 *** [buildworld] Error code 2 1150 1151 this likely due to an old instance of make in 1152 ${MAKEPATH} (${MAKEOBJDIRPREFIX}${.CURDIR}/make.${MACHINE}) 1153 which src/Makefile will use that blindly, if it exists, so if 1154 you see the above error: 1155 1156 rm -rf `make -V MAKEPATH` 1157 1158 should resolve it. 1159 116020130516: 1161 Use bmake by default. 1162 Whereas before one could choose to build with bmake via 1163 -DWITH_BMAKE one must now use -DWITHOUT_BMAKE to use the old 1164 make. The goal is to remove these knobs for 10-RELEASE. 1165 1166 It is worth noting that bmake (like gmake) treats the command 1167 line as the unit of failure, rather than statements within the 1168 command line. Thus '(cd some/where && dosomething)' is safer 1169 than 'cd some/where; dosomething'. The '()' allows consistent 1170 behavior in parallel build. 1171 117220130429: 1173 Fix a bug that allows NFS clients to issue READDIR on files. 1174 117520130426: 1176 The WITHOUT_IDEA option has been removed because 1177 the IDEA patent expired. 1178 117920130426: 1180 The sysctl which controls TRIM support under ZFS has been renamed 1181 from vfs.zfs.trim_disable -> vfs.zfs.trim.enabled and has been 1182 enabled by default. 1183 118420130425: 1185 The mergemaster command now uses the default MAKEOBJDIRPREFIX 1186 rather than creating it's own in the temporary directory in 1187 order allow access to bootstrapped versions of tools such as 1188 install and mtree. When upgrading from version of FreeBSD where 1189 the install command does not support -l, you will need to 1190 install a new mergemaster command if mergemaster -p is required. 1191 This can be accomplished with the command (cd src/usr.sbin/mergemaster 1192 && make install). 1193 119420130404: 1195 Legacy ATA stack, disabled and replaced by new CAM-based one since 1196 FreeBSD 9.0, completely removed from the sources. Kernel modules 1197 atadisk and atapi*, user-level tools atacontrol and burncd are 1198 removed. Kernel option `options ATA_CAM` is now permanently enabled 1199 and removed. 1200 120120130319: 1202 SOCK_CLOEXEC and SOCK_NONBLOCK flags have been added to socket(2) 1203 and socketpair(2). Software, in particular Kerberos, may 1204 automatically detect and use these during building. The resulting 1205 binaries will not work on older kernels. 1206 120720130308: 1208 CTL_DISABLE has also been added to the sparc64 GENERIC (for further 1209 information, see the respective 20130304 entry). 1210 121120130304: 1212 Recent commits to callout(9) changed the size of struct callout, 1213 so the KBI is probably heavily disturbed. Also, some functions 1214 in callout(9)/sleep(9)/sleepqueue(9)/condvar(9) KPIs were replaced 1215 by macros. Every kernel module using it won't load, so rebuild 1216 is requested. 1217 1218 The ctl device has been re-enabled in GENERIC for i386 and amd64, 1219 but does not initialize by default (because of the new CTL_DISABLE 1220 option) to save memory. To re-enable it, remove the CTL_DISABLE 1221 option from the kernel config file or set kern.cam.ctl.disable=0 1222 in /boot/loader.conf. 1223 122420130301: 1225 The ctl device has been disabled in GENERIC for i386 and amd64. 1226 This was done due to the extra memory being allocated at system 1227 initialisation time by the ctl driver which was only used if 1228 a CAM target device was created. This makes a FreeBSD system 1229 unusable on 128MB or less of RAM. 1230 123120130208: 1232 A new compression method (lz4) has been merged to -HEAD. Please 1233 refer to zpool-features(7) for more information. 1234 1235 Please refer to the "ZFS notes" section of this file for information 1236 on upgrading boot ZFS pools. 1237 123820130129: 1239 A BSD-licensed patch(1) variant has been added and is installed 1240 as bsdpatch, being the GNU version the default patch. 1241 To inverse the logic and use the BSD-licensed one as default, 1242 while having the GNU version installed as gnupatch, rebuild 1243 and install world with the WITH_BSD_PATCH knob set. 1244 124520130121: 1246 Due to the use of the new -l option to install(1) during build 1247 and install, you must take care not to directly set the INSTALL 1248 make variable in your /etc/make.conf, /etc/src.conf, or on the 1249 command line. If you wish to use the -C flag for all installs 1250 you may be able to add INSTALL+=-C to /etc/make.conf or 1251 /etc/src.conf. 1252 125320130118: 1254 The install(1) option -M has changed meaning and now takes an 1255 argument that is a file or path to append logs to. In the 1256 unlikely event that -M was the last option on the command line 1257 and the command line contained at least two files and a target 1258 directory the first file will have logs appended to it. The -M 1259 option served little practical purpose in the last decade so its 1260 use is expected to be extremely rare. 1261 126220121223: 1263 After switching to Clang as the default compiler some users of ZFS 1264 on i386 systems started to experience stack overflow kernel panics. 1265 Please consider using 'options KSTACK_PAGES=4' in such configurations. 1266 126720121222: 1268 GEOM_LABEL now mangles label names read from file system metadata. 1269 Mangling affect labels containing spaces, non-printable characters, 1270 '%' or '"'. Device names in /etc/fstab and other places may need to 1271 be updated. 1272 127320121217: 1274 By default, only the 10 most recent kernel dumps will be saved. To 1275 restore the previous behaviour (no limit on the number of kernel dumps 1276 stored in the dump directory) add the following line to /etc/rc.conf: 1277 1278 savecore_flags="" 1279 128020121201: 1281 With the addition of auditdistd(8), a new auditdistd user is now 1282 required during installworld. "mergemaster -p" can be used to 1283 add the user prior to installworld, as documented in the handbook. 1284 128520121117: 1286 The sin6_scope_id member variable in struct sockaddr_in6 is now 1287 filled by the kernel before passing the structure to the userland via 1288 sysctl or routing socket. This means the KAME-specific embedded scope 1289 id in sin6_addr.s6_addr[2] is always cleared in userland application. 1290 This behavior can be controlled by net.inet6.ip6.deembed_scopeid. 1291 __FreeBSD_version is bumped to 1000025. 1292 129320121105: 1294 On i386 and amd64 systems WITH_CLANG_IS_CC is now the default. 1295 This means that the world and kernel will be compiled with clang 1296 and that clang will be installed as /usr/bin/cc, /usr/bin/c++, 1297 and /usr/bin/cpp. To disable this behavior and revert to building 1298 with gcc, compile with WITHOUT_CLANG_IS_CC. Really old versions 1299 of current may need to bootstrap WITHOUT_CLANG first if the clang 1300 build fails (its compatibility window doesn't extend to the 9 stable 1301 branch point). 1302 130320121102: 1304 The IPFIREWALL_FORWARD kernel option has been removed. Its 1305 functionality now turned on by default. 1306 130720121023: 1308 The ZERO_COPY_SOCKET kernel option has been removed and 1309 split into SOCKET_SEND_COW and SOCKET_RECV_PFLIP. 1310 NB: SOCKET_SEND_COW uses the VM page based copy-on-write 1311 mechanism which is not safe and may result in kernel crashes. 1312 NB: The SOCKET_RECV_PFLIP mechanism is useless as no current 1313 driver supports disposeable external page sized mbuf storage. 1314 Proper replacements for both zero-copy mechanisms are under 1315 consideration and will eventually lead to complete removal 1316 of the two kernel options. 1317 131820121023: 1319 The IPv4 network stack has been converted to network byte 1320 order. The following modules need to be recompiled together 1321 with kernel: carp(4), divert(4), gif(4), siftr(4), gre(4), 1322 pf(4), ipfw(4), ng_ipfw(4), stf(4). 1323 132420121022: 1325 Support for non-MPSAFE filesystems was removed from VFS. The 1326 VFS_VERSION was bumped, all filesystem modules shall be 1327 recompiled. 1328 132920121018: 1330 All the non-MPSAFE filesystems have been disconnected from 1331 the build. The full list includes: codafs, hpfs, ntfs, nwfs, 1332 portalfs, smbfs, xfs. 1333 133420121016: 1335 The interface cloning API and ABI has changed. The following 1336 modules need to be recompiled together with kernel: 1337 ipfw(4), pfsync(4), pflog(4), usb(4), wlan(4), stf(4), 1338 vlan(4), disc(4), edsc(4), if_bridge(4), gif(4), tap(4), 1339 faith(4), epair(4), enc(4), tun(4), if_lagg(4), gre(4). 1340 134120121015: 1342 The sdhci driver was split in two parts: sdhci (generic SD Host 1343 Controller logic) and sdhci_pci (actual hardware driver). 1344 No kernel config modifications are required, but if you 1345 load sdhc as a module you must switch to sdhci_pci instead. 1346 134720121014: 1348 Import the FUSE kernel and userland support into base system. 1349 135020121013: 1351 The GNU sort(1) program has been removed since the BSD-licensed 1352 sort(1) has been the default for quite some time and no serious 1353 problems have been reported. The corresponding WITH_GNU_SORT 1354 knob has also gone. 1355 135620121006: 1357 The pfil(9) API/ABI for AF_INET family has been changed. Packet 1358 filtering modules: pf(4), ipfw(4), ipfilter(4) need to be recompiled 1359 with new kernel. 1360 136120121001: 1362 The net80211(4) ABI has been changed to allow for improved driver 1363 PS-POLL and power-save support. All wireless drivers need to be 1364 recompiled to work with the new kernel. 1365 136620120913: 1367 The random(4) support for the VIA hardware random number 1368 generator (`PADLOCK') is no longer enabled unconditionally. 1369 Add the padlock_rng device in the custom kernel config if 1370 needed. The GENERIC kernels on i386 and amd64 do include the 1371 device, so the change only affects the custom kernel 1372 configurations. 1373 137420120908: 1375 The pf(4) packet filter ABI has been changed. pfctl(8) and 1376 snmp_pf module need to be recompiled to work with new kernel. 1377 137820120828: 1379 A new ZFS feature flag "com.delphix:empty_bpobj" has been merged 1380 to -HEAD. Pools that have empty_bpobj in active state can not be 1381 imported read-write with ZFS implementations that do not support 1382 this feature. For more information read the zpool-features(5) 1383 manual page. 1384 138520120727: 1386 The sparc64 ZFS loader has been changed to no longer try to auto- 1387 detect ZFS providers based on diskN aliases but now requires these 1388 to be explicitly listed in the OFW boot-device environment variable. 1389 139020120712: 1391 The OpenSSL has been upgraded to 1.0.1c. Any binaries requiring 1392 libcrypto.so.6 or libssl.so.6 must be recompiled. Also, there are 1393 configuration changes. Make sure to merge /etc/ssl/openssl.cnf. 1394 139520120712: 1396 The following sysctls and tunables have been renamed for consistency 1397 with other variables: 1398 kern.cam.da.da_send_ordered -> kern.cam.da.send_ordered 1399 kern.cam.ada.ada_send_ordered -> kern.cam.ada.send_ordered 1400 140120120628: 1402 The sort utility has been replaced with BSD sort. For now, GNU sort 1403 is also available as "gnusort" or the default can be set back to 1404 GNU sort by setting WITH_GNU_SORT. In this case, BSD sort will be 1405 installed as "bsdsort". 1406 140720120611: 1408 A new version of ZFS (pool version 5000) has been merged to -HEAD. 1409 Starting with this version the old system of ZFS pool versioning 1410 is superseded by "feature flags". This concept enables forward 1411 compatibility against certain future changes in functionality of ZFS 1412 pools. The first read-only compatible "feature flag" for ZFS pools 1413 is named "com.delphix:async_destroy". For more information 1414 read the new zpool-features(5) manual page. 1415 Please refer to the "ZFS notes" section of this file for information 1416 on upgrading boot ZFS pools. 1417 141820120417: 1419 The malloc(3) implementation embedded in libc now uses sources imported 1420 as contrib/jemalloc. The most disruptive API change is to 1421 /etc/malloc.conf. If your system has an old-style /etc/malloc.conf, 1422 delete it prior to installworld, and optionally re-create it using the 1423 new format after rebooting. See malloc.conf(5) for details 1424 (specifically the TUNING section and the "opt.*" entries in the MALLCTL 1425 NAMESPACE section). 1426 142720120328: 1428 Big-endian MIPS TARGET_ARCH values no longer end in "eb". mips64eb 1429 is now spelled mips64. mipsn32eb is now spelled mipsn32. mipseb is 1430 now spelled mips. This is to aid compatibility with third-party 1431 software that expects this naming scheme in uname(3). Little-endian 1432 settings are unchanged. If you are updating a big-endian mips64 machine 1433 from before this change, you may need to set MACHINE_ARCH=mips64 in 1434 your environment before the new build system will recognize your machine. 1435 143620120306: 1437 Disable by default the option VFS_ALLOW_NONMPSAFE for all supported 1438 platforms. 1439 144020120229: 1441 Now unix domain sockets behave "as expected" on nullfs(5). Previously 1442 nullfs(5) did not pass through all behaviours to the underlying layer, 1443 as a result if we bound to a socket on the lower layer we could connect 1444 only to the lower path; if we bound to the upper layer we could connect 1445 only to the upper path. The new behavior is one can connect to both the 1446 lower and the upper paths regardless what layer path one binds to. 1447 144820120211: 1449 The getifaddrs upgrade path broken with 20111215 has been restored. 1450 If you have upgraded in between 20111215 and 20120209 you need to 1451 recompile libc again with your kernel. You still need to recompile 1452 world to be able to configure CARP but this restriction already 1453 comes from 20111215. 1454 145520120114: 1456 The set_rcvar() function has been removed from /etc/rc.subr. All 1457 base and ports rc.d scripts have been updated, so if you have a 1458 port installed with a script in /usr/local/etc/rc.d you can either 1459 hand-edit the rcvar= line, or reinstall the port. 1460 1461 An easy way to handle the mass-update of /etc/rc.d: 1462 rm /etc/rc.d/* && mergemaster -i 1463 146420120109: 1465 panic(9) now stops other CPUs in the SMP systems, disables interrupts 1466 on the current CPU and prevents other threads from running. 1467 This behavior can be reverted using the kern.stop_scheduler_on_panic 1468 tunable/sysctl. 1469 The new behavior can be incompatible with kern.sync_on_panic. 1470 147120111215: 1472 The carp(4) facility has been changed significantly. Configuration 1473 of the CARP protocol via ifconfig(8) has changed, as well as format 1474 of CARP events submitted to devd(8) has changed. See manual pages 1475 for more information. The arpbalance feature of carp(4) is currently 1476 not supported anymore. 1477 1478 Size of struct in_aliasreq, struct in6_aliasreq has changed. User 1479 utilities using SIOCAIFADDR, SIOCAIFADDR_IN6, e.g. ifconfig(8), 1480 need to be recompiled. 1481 148220111122: 1483 The acpi_wmi(4) status device /dev/wmistat has been renamed to 1484 /dev/wmistat0. 1485 148620111108: 1487 The option VFS_ALLOW_NONMPSAFE option has been added in order to 1488 explicitely support non-MPSAFE filesystems. 1489 It is on by default for all supported platform at this present 1490 time. 1491 149220111101: 1493 The broken amd(4) driver has been replaced with esp(4) in the amd64, 1494 i386 and pc98 GENERIC kernel configuration files. 1495 149620110930: 1497 sysinstall has been removed 1498 149920110923: 1500 The stable/9 branch created in subversion. This corresponds to the 1501 RELENG_9 branch in CVS. 1502 1503COMMON ITEMS: 1504 1505 General Notes 1506 ------------- 1507 Avoid using make -j when upgrading. While generally safe, there are 1508 sometimes problems using -j to upgrade. If your upgrade fails with 1509 -j, please try again without -j. From time to time in the past there 1510 have been problems using -j with buildworld and/or installworld. This 1511 is especially true when upgrading between "distant" versions (eg one 1512 that cross a major release boundary or several minor releases, or when 1513 several months have passed on the -current branch). 1514 1515 Sometimes, obscure build problems are the result of environment 1516 poisoning. This can happen because the make utility reads its 1517 environment when searching for values for global variables. To run 1518 your build attempts in an "environmental clean room", prefix all make 1519 commands with 'env -i '. See the env(1) manual page for more details. 1520 1521 When upgrading from one major version to another it is generally best 1522 to upgrade to the latest code in the currently installed branch first, 1523 then do an upgrade to the new branch. This is the best-tested upgrade 1524 path, and has the highest probability of being successful. Please try 1525 this approach before reporting problems with a major version upgrade. 1526 1527 When upgrading a live system, having a root shell around before 1528 installing anything can help undo problems. Not having a root shell 1529 around can lead to problems if pam has changed too much from your 1530 starting point to allow continued authentication after the upgrade. 1531 1532 This file should be read as a log of events. When a later event changes 1533 information of a prior event, the prior event should not be deleted. 1534 Instead, a pointer to the entry with the new information should be 1535 placed in the old entry. Readers of this file should also sanity check 1536 older entries before relying on them blindly. Authors of new entries 1537 should write them with this in mind. 1538 1539 ZFS notes 1540 --------- 1541 When upgrading the boot ZFS pool to a new version, always follow 1542 these two steps: 1543 1544 1.) recompile and reinstall the ZFS boot loader and boot block 1545 (this is part of "make buildworld" and "make installworld") 1546 1547 2.) update the ZFS boot block on your boot drive 1548 1549 The following example updates the ZFS boot block on the first 1550 partition (freebsd-boot) of a GPT partitioned drive ada0: 1551 "gpart bootcode -p /boot/gptzfsboot -i 1 ada0" 1552 1553 Non-boot pools do not need these updates. 1554 1555 To build a kernel 1556 ----------------- 1557 If you are updating from a prior version of FreeBSD (even one just 1558 a few days old), you should follow this procedure. It is the most 1559 failsafe as it uses a /usr/obj tree with a fresh mini-buildworld, 1560 1561 make kernel-toolchain 1562 make -DALWAYS_CHECK_MAKE buildkernel KERNCONF=YOUR_KERNEL_HERE 1563 make -DALWAYS_CHECK_MAKE installkernel KERNCONF=YOUR_KERNEL_HERE 1564 1565 To test a kernel once 1566 --------------------- 1567 If you just want to boot a kernel once (because you are not sure 1568 if it works, or if you want to boot a known bad kernel to provide 1569 debugging information) run 1570 make installkernel KERNCONF=YOUR_KERNEL_HERE KODIR=/boot/testkernel 1571 nextboot -k testkernel 1572 1573 To just build a kernel when you know that it won't mess you up 1574 -------------------------------------------------------------- 1575 This assumes you are already running a CURRENT system. Replace 1576 ${arch} with the architecture of your machine (e.g. "i386", 1577 "arm", "amd64", "ia64", "pc98", "sparc64", "powerpc", "mips", etc). 1578 1579 cd src/sys/${arch}/conf 1580 config KERNEL_NAME_HERE 1581 cd ../compile/KERNEL_NAME_HERE 1582 make depend 1583 make 1584 make install 1585 1586 If this fails, go to the "To build a kernel" section. 1587 1588 To rebuild everything and install it on the current system. 1589 ----------------------------------------------------------- 1590 # Note: sometimes if you are running current you gotta do more than 1591 # is listed here if you are upgrading from a really old current. 1592 1593 <make sure you have good level 0 dumps> 1594 make buildworld 1595 make kernel KERNCONF=YOUR_KERNEL_HERE 1596 [1] 1597 <reboot in single user> [3] 1598 mergemaster -Fp [5] 1599 make installworld 1600 mergemaster -Fi [4] 1601 make delete-old [6] 1602 <reboot> 1603 1604 To cross-install current onto a separate partition 1605 -------------------------------------------------- 1606 # In this approach we use a separate partition to hold 1607 # current's root, 'usr', and 'var' directories. A partition 1608 # holding "/", "/usr" and "/var" should be about 2GB in 1609 # size. 1610 1611 <make sure you have good level 0 dumps> 1612 <boot into -stable> 1613 make buildworld 1614 make buildkernel KERNCONF=YOUR_KERNEL_HERE 1615 <maybe newfs current's root partition> 1616 <mount current's root partition on directory ${CURRENT_ROOT}> 1617 make installworld DESTDIR=${CURRENT_ROOT} -DDB_FROM_SRC 1618 make distribution DESTDIR=${CURRENT_ROOT} # if newfs'd 1619 make installkernel KERNCONF=YOUR_KERNEL_HERE DESTDIR=${CURRENT_ROOT} 1620 cp /etc/fstab ${CURRENT_ROOT}/etc/fstab # if newfs'd 1621 <edit ${CURRENT_ROOT}/etc/fstab to mount "/" from the correct partition> 1622 <reboot into current> 1623 <do a "native" rebuild/install as described in the previous section> 1624 <maybe install compatibility libraries from ports/misc/compat*> 1625 <reboot> 1626 1627 1628 To upgrade in-place from stable to current 1629 ---------------------------------------------- 1630 <make sure you have good level 0 dumps> 1631 make buildworld [9] 1632 make kernel KERNCONF=YOUR_KERNEL_HERE [8] 1633 [1] 1634 <reboot in single user> [3] 1635 mergemaster -Fp [5] 1636 make installworld 1637 mergemaster -Fi [4] 1638 make delete-old [6] 1639 <reboot> 1640 1641 Make sure that you've read the UPDATING file to understand the 1642 tweaks to various things you need. At this point in the life 1643 cycle of current, things change often and you are on your own 1644 to cope. The defaults can also change, so please read ALL of 1645 the UPDATING entries. 1646 1647 Also, if you are tracking -current, you must be subscribed to 1648 freebsd-current@freebsd.org. Make sure that before you update 1649 your sources that you have read and understood all the recent 1650 messages there. If in doubt, please track -stable which has 1651 much fewer pitfalls. 1652 1653 [1] If you have third party modules, such as vmware, you 1654 should disable them at this point so they don't crash your 1655 system on reboot. 1656 1657 [3] From the bootblocks, boot -s, and then do 1658 fsck -p 1659 mount -u / 1660 mount -a 1661 cd src 1662 adjkerntz -i # if CMOS is wall time 1663 Also, when doing a major release upgrade, it is required that 1664 you boot into single user mode to do the installworld. 1665 1666 [4] Note: This step is non-optional. Failure to do this step 1667 can result in a significant reduction in the functionality of the 1668 system. Attempting to do it by hand is not recommended and those 1669 that pursue this avenue should read this file carefully, as well 1670 as the archives of freebsd-current and freebsd-hackers mailing lists 1671 for potential gotchas. The -U option is also useful to consider. 1672 See mergemaster(8) for more information. 1673 1674 [5] Usually this step is a noop. However, from time to time 1675 you may need to do this if you get unknown user in the following 1676 step. It never hurts to do it all the time. You may need to 1677 install a new mergemaster (cd src/usr.sbin/mergemaster && make 1678 install) after the buildworld before this step if you last updated 1679 from current before 20130425 or from -stable before 20130430. 1680 1681 [6] This only deletes old files and directories. Old libraries 1682 can be deleted by "make delete-old-libs", but you have to make 1683 sure that no program is using those libraries anymore. 1684 1685 [8] In order to have a kernel that can run the 4.x binaries needed to 1686 do an installworld, you must include the COMPAT_FREEBSD4 option in 1687 your kernel. Failure to do so may leave you with a system that is 1688 hard to boot to recover. A similar kernel option COMPAT_FREEBSD5 is 1689 required to run the 5.x binaries on more recent kernels. And so on 1690 for COMPAT_FREEBSD6 and COMPAT_FREEBSD7. 1691 1692 Make sure that you merge any new devices from GENERIC since the 1693 last time you updated your kernel config file. 1694 1695 [9] When checking out sources, you must include the -P flag to have 1696 cvs prune empty directories. 1697 1698 If CPUTYPE is defined in your /etc/make.conf, make sure to use the 1699 "?=" instead of the "=" assignment operator, so that buildworld can 1700 override the CPUTYPE if it needs to. 1701 1702 MAKEOBJDIRPREFIX must be defined in an environment variable, and 1703 not on the command line, or in /etc/make.conf. buildworld will 1704 warn if it is improperly defined. 1705FORMAT: 1706 1707This file contains a list, in reverse chronological order, of major 1708breakages in tracking -current. It is not guaranteed to be a complete 1709list of such breakages, and only contains entries since September 23, 2011. 1710If you need to see UPDATING entries from before that date, you will need 1711to fetch an UPDATING file from an older FreeBSD release. 1712 1713Copyright information: 1714 1715Copyright 1998-2009 M.
