UPDATING revision 318197
1Updating Information for FreeBSD current users. 2 3This file is maintained and copyrighted by M. Warner Losh <imp@freebsd.org>. 4See end of file for further details. For commonly done items, please see the 5COMMON ITEMS: section later in the file. These instructions assume that you 6basically know what you are doing. If not, then please consult the FreeBSD 7handbook: 8 9 http://www.freebsd.org/doc/en_US.ISO8859-1/books/handbook/makeworld.html 10 11Items affecting the ports and packages system can be found in 12/usr/ports/UPDATING. Please read that file before running portupgrade. 13 14NOTE: FreeBSD has switched from gcc to clang. If you have trouble bootstrapping 15from older versions of FreeBSD, try WITHOUT_CLANG and WITH_GCC to bootstrap to 16the tip of head, and then rebuild without this option. The bootstrap process 17from older version of current across the gcc/clang cutover is a bit fragile. 18 1920170511: 20 The mmcsd.ko module now additionally depends on geom_flashmap.ko. 21 Also, mmc.ko and mmcsd.ko need to be a matching pair built from the 22 same source (previously, the dependency of mmcsd.ko on mmc.ko was 23 missing, but mmcsd.ko now will refuse to load if it is incompatible 24 with mmc.ko). 25 2620170414: 27 Binds and sends to the loopback addresses, IPv6 and IPv4, will now 28 use any explicitly assigned loopback address available in the jail 29 instead of using the first assigned address of the jail. 30 3120170413: 32 As of r316810 for ipfilter, keep frags is no longer assumed when 33 keep state is specified in a rule. r316810 aligns ipfilter with 34 documentation in man pages separating keep frags from keep state. 35 This allows keep state to specified without forcing keep frags 36 and allows keep frags to be specified independently of keep state. 37 To maintain previous behaviour, also specify keep frags with 38 keep state (as documented in ipf.conf.5). 39 4020170402: 41 Clang, llvm, lldb, compiler-rt and libc++ have been upgraded to 4.0.0. 42 Please see the 20141231 entry below for information about prerequisites 43 and upgrading, if you are not already using clang 3.5.0 or higher. 44 4520170323: 46 The code that provides support for ZFS .zfs/ directory functionality 47 has been reimplemented. It's not possible now to create a snapshot 48 by mkdir under .zfs/snapshot/. That should be the only user visible 49 change. 50 5120170319: 52 Many changes in the IPsec code have been merged from the FreeBSD-CURRENT 53 branch. The IPSEC_FILTERTUNNEL kernel option is removed in favour of 54 corresponding sysctl. The IPSEC_NAT_T kernel option is also removed, 55 and now NAT-T is supported by default. Security associations now use 56 the single namespace for SPI allocation, so if you use several manually 57 configured security associations with the same SPI, this configuration 58 needs modification. 59 6020161217: 61 Clang, llvm, lldb, compiler-rt and libc++ have been upgraded to 3.9.1. 62 Please see the 20141231 entry below for information about prerequisites 63 and upgrading, if you are not already using clang 3.5.0 or higher. 64 6520161124: 66 Clang, llvm, lldb, compiler-rt and libc++ have been upgraded to 3.9.0. 67 Please see the 20141231 entry below for information about prerequisites 68 and upgrading, if you are not already using clang 3.5.0 or higher. 69 7020161119: 71 The layout of the pmap structure has changed for powerpc to put the pmap 72 statistics at the front for all CPU variations. libkvm(3) and all tools 73 that link against it need to be recompiled. 74 7520161030: 76 isl(4) and cyapa(4) drivers now require a new driver, 77 chromebook_platform(4), to work properly on Chromebook-class hardware. 78 On other types of hardware the drivers may need to be configured using 79 device hints. Please see the corresponding manual pages for details. 80 8120161210: 82 Relocatable object files with the extension of .So have been renamed 83 to use an extension of .pico instead. The purpose of this change is 84 to avoid a name clash with shared libraries on case-insensitive file 85 systems. On those file systems, foo.So is the same file as foo.so. 86 8720160622: 88 The libc stub for the pipe(2) system call has been replaced with 89 a wrapper that calls the pipe2(2) system call and the pipe(2) 90 system call is now only implemented by the kernels that include 91 "options COMPAT_FREEBSD10" in their config file (this is the 92 default). Users should ensure that this option is enabled in 93 their kernel or upgrade userspace to r302092 before upgrading their 94 kernel. 95 9620160527: 97 CAM will now strip leading spaces from SCSI disks' serial numbers. 98 This will effect users who create UFS filesystems on SCSI disks using 99 those disk's diskid device nodes. For example, if /etc/fstab 100 previously contained a line like 101 "/dev/diskid/DISK-%20%20%20%20%20%20%20ABCDEFG0123456", you should 102 change it to "/dev/diskid/DISK-ABCDEFG0123456". Users of geom 103 transforms like gmirror may also be affected. ZFS users should 104 generally be fine. 105 10620160523: 107 The bitstring(3) API has been updated with new functionality and 108 improved performance. But it is binary-incompatible with the old API. 109 Objects built with the new headers may not be linked against objects 110 built with the old headers. 111 11220160520: 113 The brk and sbrk functions have been removed from libc on arm64. 114 Binutils from ports has been updated to not link to these 115 functions and should be updated to the latest version before 116 installing a new libc. 117 11820160517: 119 The armv6 port now defaults to hard float ABI. Limited support 120 for running both hardfloat and soft float on the same system 121 is available using the libraries installed with -DWITH_LIBSOFT. 122 This has only been tested as an upgrade path for installworld 123 and packages may fail or need manual intervention to run. New 124 packages will be needed. 125 126 To update an existing self-hosted armv6hf system, you must add 127 TARGET_ARCH=armv6 on the make command line for both the build 128 and the install steps. 129 13020160510: 131 Kernel modules compiled outside of a kernel build now default to 132 installing to /boot/modules instead of /boot/kernel. Many kernel 133 modules built this way (such as those in ports) already overrode 134 KMODDIR explicitly to install into /boot/modules. However, 135 manually building and installing a module from /sys/modules will 136 now install to /boot/modules instead of /boot/kernel. 137 13820160414: 139 The CAM I/O scheduler has been committed to the kernel. There should be 140 no user visible impact. This does enable NCQ Trim on ada SSDs. While the 141 list of known rogues that claim support for this but actually corrupt 142 data is believed to be complete, be on the lookout for data 143 corruption. The known rogue list is believed to be complete: 144 145 o Crucial MX100, M550 drives with MU01 firmware. 146 o Micron M510 and M550 drives with MU01 firmware. 147 o Micron M500 prior to MU07 firmware 148 o Samsung 830, 840, and 850 all firmwares 149 o FCCT M500 all firmwares 150 151 Crucial has firmware http://www.crucial.com/usa/en/support-ssd-firmware 152 with working NCQ TRIM. For Micron branded drives, see your sales rep for 153 updated firmware. Black listed drives will work correctly because these 154 drives work correctly so long as no NCQ TRIMs are sent to them. Given 155 this list is the same as found in Linux, it's believed there are no 156 other rogues in the market place. All other models from the above 157 vendors work. 158 159 To be safe, if you are at all concerned, you can quirk each of your 160 drives to prevent NCQ from being sent by setting: 161 kern.cam.ada.X.quirks="0x2" 162 in loader.conf. If the drive requires the 4k sector quirk, set the 163 quirks entry to 0x3. 164 16520160330: 166 The FAST_DEPEND build option has been removed and its functionality is 167 now the one true way. The old mkdep(1) style of 'make depend' has 168 been removed. See 20160311 for further details. 169 17020160317: 171 Resource range types have grown from unsigned long to uintmax_t. All 172 drivers, and anything using libdevinfo, need to be recompiled. 173 17420160311: 175 WITH_FAST_DEPEND is now enabled by default for in-tree and out-of-tree 176 builds. It no longer runs mkdep(1) during 'make depend', and the 177 'make depend' stage can safely be skipped now as it is auto ran 178 when building 'make all' and will generate all SRCS and DPSRCS before 179 building anything else. Dependencies are gathered at compile time with 180 -MF flags kept in separate .depend files per object file. Users should 181 run 'make cleandepend' once if using -DNO_CLEAN to clean out older 182 stale .depend files. 183 18420160306: 185 On amd64, clang 3.8.0 can now insert sections of type AMD64_UNWIND into 186 kernel modules. Therefore, if you load any kernel modules at boot time, 187 please install the boot loaders after you install the kernel, but before 188 rebooting, e.g.: 189 190 make buildworld 191 make kernel KERNCONF=YOUR_KERNEL_HERE 192 make -C sys/boot install 193 <reboot in single user> 194 195 Then follow the usual steps, described in the General Notes section, 196 below. 197 19820160305: 199 Clang, llvm, lldb and compiler-rt have been upgraded to 3.8.0. Please 200 see the 20141231 entry below for information about prerequisites and 201 upgrading, if you are not already using clang 3.5.0 or higher. 202 20320160301: 204 The AIO subsystem is now a standard part of the kernel. The 205 VFS_AIO kernel option and aio.ko kernel module have been removed. 206 Due to stability concerns, asynchronous I/O requests are only 207 permitted on sockets and raw disks by default. To enable 208 asynchronous I/O requests on all file types, set the 209 vfs.aio.enable_unsafe sysctl to a non-zero value. 210 21120160226: 212 The ELF object manipulation tool objcopy is now provided by the 213 ELF Tool Chain project rather than by GNU binutils. It should be a 214 drop-in replacement, with the addition of arm64 support. The 215 (temporary) src.conf knob WITHOUT_ELFCOPY_AS_OBJCOPY knob may be set 216 to obtain the GNU version if necessary. 217 21820160129: 219 Building ZFS pools on top of zvols is prohibited by default. That 220 feature has never worked safely; it's always been prone to deadlocks. 221 Using a zvol as the backing store for a VM guest's virtual disk will 222 still work, even if the guest is using ZFS. Legacy behavior can be 223 restored by setting vfs.zfs.vol.recursive=1. 224 22520160119: 226 The NONE and HPN patches has been removed from OpenSSH. They are 227 still available in the security/openssh-portable port. 228 22920160113: 230 With the addition of ypldap(8), a new _ypldap user is now required 231 during installworld. "mergemaster -p" can be used to add the user 232 prior to installworld, as documented in the handbook. 233 23420151216: 235 The tftp loader (pxeboot) now uses the option root-path directive. As a 236 consequence it no longer looks for a pxeboot.4th file on the tftp 237 server. Instead it uses the regular /boot infrastructure as with the 238 other loaders. 239 24020151211: 241 The code to start recording plug and play data into the modules has 242 been committed. While the old tools will properly build a new kernel, 243 a number of warnings about "unknown metadata record 4" will be produced 244 for an older kldxref. To avoid such warnings, make sure to rebuild 245 the kernel toolchain (or world). Make sure that you have r292078 or 246 later when trying to build 292077 or later before rebuilding. 247 24820151207: 249 Debug data files are now built by default with 'make buildworld' and 250 installed with 'make installworld'. This facilitates debugging but 251 requires more disk space both during the build and for the installed 252 world. Debug files may be disabled by setting WITHOUT_DEBUG_FILES=yes 253 in src.conf(5). 254 25520151130: 256 r291527 changed the internal interface between the nfsd.ko and 257 nfscommon.ko modules. As such, they must both be upgraded to-gether. 258 __FreeBSD_version has been bumped because of this. 259 26020151108: 261 Add support for unicode collation strings leads to a change of 262 order of files listed by ls(1) for example. To get back to the old 263 behaviour, set LC_COLLATE environment variable to "C". 264 265 Databases administrators will need to reindex their databases given 266 collation results will be different. 267 268 Due to a bug in install(1) it is recommended to remove the ancient 269 locales before running make installworld. 270 271 rm -rf /usr/share/locale/* 272 27320151030: 274 The OpenSSL has been upgraded to 1.0.2d. Any binaries requiring 275 libcrypto.so.7 or libssl.so.7 must be recompiled. 276 27720151020: 278 Qlogic 24xx/25xx firmware images were updated from 5.5.0 to 7.3.0. 279 Kernel modules isp_2400_multi and isp_2500_multi were removed and 280 should be replaced with isp_2400 and isp_2500 modules respectively. 281 28220151017: 283 The build previously allowed using 'make -n' to not recurse into 284 sub-directories while showing what commands would be executed, and 285 'make -n -n' to recursively show commands. Now 'make -n' will recurse 286 and 'make -N' will not. 287 28820151012: 289 If you specify SENDMAIL_MC or SENDMAIL_CF in make.conf, mergemaster 290 and etcupdate will now use this file. A custom sendmail.cf is now 291 updated via this mechanism rather than via installworld. If you had 292 excluded sendmail.cf in mergemaster.rc or etcupdate.conf, you may 293 want to remove the exclusion or change it to "always install". 294 /etc/mail/sendmail.cf is now managed the same way regardless of 295 whether SENDMAIL_MC/SENDMAIL_CF is used. If you are not using 296 SENDMAIL_MC/SENDMAIL_CF there should be no change in behavior. 297 29820151011: 299 Compatibility shims for legacy ATA device names have been removed. 300 It includes ATA_STATIC_ID kernel option, kern.cam.ada.legacy_aliases 301 and kern.geom.raid.legacy_aliases loader tunables, kern.devalias.* 302 environment variables, /dev/ad* and /dev/ar* symbolic links. 303 30420151006: 305 Clang, llvm, lldb, compiler-rt and libc++ have been upgraded to 3.7.0. 306 Please see the 20141231 entry below for information about prerequisites 307 and upgrading, if you are not already using clang 3.5.0 or higher. 308 30920150924: 310 Kernel debug files have been moved to /usr/lib/debug/boot/kernel/, 311 and renamed from .symbols to .debug. This reduces the size requirements 312 on the boot partition or file system and provides consistency with 313 userland debug files. 314 315 When using the supported kernel installation method the 316 /usr/lib/debug/boot/kernel directory will be renamed (to kernel.old) 317 as is done with /boot/kernel. 318 319 Developers wishing to maintain the historical behavior of installing 320 debug files in /boot/kernel/ can set KERN_DEBUGDIR="" in src.conf(5). 321 32220150827: 323 The wireless drivers had undergone changes that remove the 'parent 324 interface' from the ifconfig -l output. The rc.d network scripts 325 used to check presence of a parent interface in the list, so old 326 scripts would fail to start wireless networking. Thus, etcupdate(3) 327 or mergemaster(8) run is required after kernel update, to update your 328 rc.d scripts in /etc. 329 33020150827: 331 pf no longer supports 'scrub fragment crop' or 'scrub fragment drop-ovl' 332 These configurations are now automatically interpreted as 333 'scrub fragment reassemble'. 334 33520150817: 336 Kernel-loadable modules for the random(4) device are back. To use 337 them, the kernel must have 338 339 device random 340 options RANDOM_LOADABLE 341 342 kldload(8) can then be used to load random_fortuna.ko 343 or random_yarrow.ko. Please note that due to the indirect 344 function calls that the loadable modules need to provide, 345 the build-in variants will be slightly more efficient. 346 347 The random(4) kernel option RANDOM_DUMMY has been retired due to 348 unpopularity. It was not all that useful anyway. 349 35020150813: 351 The WITHOUT_ELFTOOLCHAIN_TOOLS src.conf(5) knob has been retired. 352 Control over building the ELF Tool Chain tools is now provided by 353 the WITHOUT_TOOLCHAIN knob. 354 35520150810: 356 The polarity of Pulse Per Second (PPS) capture events with the 357 uart(4) driver has been corrected. Prior to this change the PPS 358 "assert" event corresponded to the trailing edge of a positive PPS 359 pulse and the "clear" event was the leading edge of the next pulse. 360 361 As the width of a PPS pulse in a typical GPS receiver is on the 362 order of 1 millisecond, most users will not notice any significant 363 difference with this change. 364 365 Anyone who has compensated for the historical polarity reversal by 366 configuring a negative offset equal to the pulse width will need to 367 remove that workaround. 368 36920150809: 370 The default group assigned to /dev/dri entries has been changed 371 from 'wheel' to 'video' with the id of '44'. If you want to have 372 access to the dri devices please add yourself to the video group 373 with: 374 375 # pw groupmod video -m $USER 376 37720150806: 378 The menu.rc and loader.rc files will now be replaced during 379 upgrades. Please migrate local changes to menu.rc.local and 380 loader.rc.local instead. 381 38220150805: 383 GNU Binutils versions of addr2line, c++filt, nm, readelf, size, 384 strings and strip have been removed. The src.conf(5) knob 385 WITHOUT_ELFTOOLCHAIN_TOOLS no longer provides the binutils tools. 386 38720150728: 388 As ZFS requires more kernel stack pages than is the default on some 389 architectures e.g. i386, it now warns if KSTACK_PAGES is less than 390 ZFS_MIN_KSTACK_PAGES (which is 4 at the time of writing). 391 392 Please consider using 'options KSTACK_PAGES=X' where X is greater 393 than or equal to ZFS_MIN_KSTACK_PAGES i.e. 4 in such configurations. 394 39520150706: 396 sendmail has been updated to 8.15.2. Starting with FreeBSD 11.0 397 and sendmail 8.15, sendmail uses uncompressed IPv6 addresses by 398 default, i.e., they will not contain "::". For example, instead 399 of ::1, it will be 0:0:0:0:0:0:0:1. This permits a zero subnet 400 to have a more specific match, such as different map entries for 401 IPv6:0:0 vs IPv6:0. This change requires that configuration 402 data (including maps, files, classes, custom ruleset, etc.) must 403 use the same format, so make certain such configuration data is 404 upgrading. As a very simple check search for patterns like 405 'IPv6:[0-9a-fA-F:]*::' and 'IPv6::'. To return to the old 406 behavior, set the m4 option confUSE_COMPRESSED_IPV6_ADDRESSES or 407 the cf option UseCompressedIPv6Addresses. 408 40920150630: 410 The default kernel entropy-processing algorithm is now 411 Fortuna, replacing Yarrow. 412 413 Assuming you have 'device random' in your kernel config 414 file, the configurations allow a kernel option to override 415 this default. You may choose *ONE* of: 416 417 options RANDOM_YARROW # Legacy /dev/random algorithm. 418 options RANDOM_DUMMY # Blocking-only driver. 419 420 If you have neither, you get Fortuna. For most people, 421 read no further, Fortuna will give a /dev/random that works 422 like it always used to, and the difference will be irrelevant. 423 424 If you remove 'device random', you get *NO* kernel-processed 425 entropy at all. This may be acceptable to folks building 426 embedded systems, but has complications. Carry on reading, 427 and it is assumed you know what you need. 428 429 *PLEASE* read random(4) and random(9) if you are in the 430 habit of tweaking kernel configs, and/or if you are a member 431 of the embedded community, wanting specific and not-usual 432 behaviour from your security subsystems. 433 434 NOTE!! If you use RANDOM_DUMMY and/or have no 'device 435 random', you will NOT have a functioning /dev/random, and 436 many cryptographic features will not work, including SSH. 437 You may also find strange behaviour from the random(3) set 438 of library functions, in particular sranddev(3), srandomdev(3) 439 and arc4random(3). The reason for this is that the KERN_ARND 440 sysctl only returns entropy if it thinks it has some to 441 share, and with RANDOM_DUMMY or no 'device random' this 442 will never happen. 443 44420150623: 445 An additional fix for the issue described in the 20150614 sendmail 446 entry below has been been committed in revision 284717. 447 44820150616: 449 FreeBSD's old make (fmake) has been removed from the system. It is 450 available as the devel/fmake port or via pkg install fmake. 451 45220150615: 453 The fix for the issue described in the 20150614 sendmail entry 454 below has been been committed in revision 284436. The work 455 around described in that entry is no longer needed unless the 456 default setting is overridden by a confDH_PARAMETERS configuration 457 setting of '5' or pointing to a 512 bit DH parameter file. 458 45920150614: 460 ALLOW_DEPRECATED_ATF_TOOLS/ATFFILE support has been removed from 461 atf.test.mk (included from bsd.test.mk). Please upgrade devel/atf 462 and devel/kyua to version 0.20+ and adjust any calling code to work 463 with Kyuafile and kyua. 464 46520150614: 466 The import of openssl to address the FreeBSD-SA-15:10.openssl 467 security advisory includes a change which rejects handshakes 468 with DH parameters below 768 bits. sendmail releases prior 469 to 8.15.2 (not yet released), defaulted to a 512 bit 470 DH parameter setting for client connections. To work around 471 this interoperability, sendmail can be configured to use a 472 2048 bit DH parameter by: 473 474 1. Edit /etc/mail/`hostname`.mc 475 2. If a setting for confDH_PARAMETERS does not exist or 476 exists and is set to a string beginning with '5', 477 replace it with '2'. 478 3. If a setting for confDH_PARAMETERS exists and is set to 479 a file path, create a new file with: 480 openssl dhparam -out /path/to/file 2048 481 4. Rebuild the .cf file: 482 cd /etc/mail/; make; make install 483 5. Restart sendmail: 484 cd /etc/mail/; make restart 485 486 A sendmail patch is coming, at which time this file will be 487 updated. 488 48920150604: 490 Generation of legacy formatted entries have been disabled by default 491 in pwd_mkdb(8), as all base system consumers of the legacy formatted 492 entries were converted to use the new format by default when the new, 493 machine independent format have been added and supported since FreeBSD 494 5.x. 495 496 Please see the pwd_mkdb(8) manual page for further details. 497 49820150525: 499 Clang and llvm have been upgraded to 3.6.1 release. Please see the 500 20141231 entry below for information about prerequisites and upgrading, 501 if you are not already using 3.5.0 or higher. 502 50320150521: 504 TI platform code switched to using vendor DTS files and this update 505 may break existing systems running on Beaglebone, Beaglebone Black, 506 and Pandaboard: 507 508 - dtb files should be regenerated/reinstalled. Filenames are the 509 same but content is different now 510 - GPIO addressing was changed, now each GPIO bank (32 pins per bank) 511 has its own /dev/gpiocX device, e.g. pin 121 on /dev/gpioc0 in old 512 addressing scheme is now pin 25 on /dev/gpioc3. 513 - Pandaboard: /etc/ttys should be updated, serial console device is 514 now /dev/ttyu2, not /dev/ttyu0 515 51620150501: 517 soelim(1) from gnu/usr.bin/groff has been replaced by usr.bin/soelim. 518 If you need the GNU extension from groff soelim(1), install groff 519 from package: pkg install groff, or via ports: textproc/groff. 520 52120150423: 522 chmod, chflags, chown and chgrp now affect symlinks in -R mode as 523 defined in symlink(7); previously symlinks were silently ignored. 524 52520150415: 526 The const qualifier has been removed from iconv(3) to comply with 527 POSIX. The ports tree is aware of this from r384038 onwards. 528 52920150416: 530 Libraries specified by LIBADD in Makefiles must have a corresponding 531 DPADD_<lib> variable to ensure correct dependencies. This is now 532 enforced in src.libnames.mk. 533 53420150324: 535 From legacy ata(4) driver was removed support for SATA controllers 536 supported by more functional drivers ahci(4), siis(4) and mvs(4). 537 Kernel modules ataahci and ataadaptec were removed completely, 538 replaced by ahci and mvs modules respectively. 539 54020150315: 541 Clang, llvm and lldb have been upgraded to 3.6.0 release. Please see 542 the 20141231 entry below for information about prerequisites and 543 upgrading, if you are not already using 3.5.0 or higher. 544 54520150307: 546 The 32-bit PowerPC kernel has been changed to a position-independent 547 executable. This can only be booted with a version of loader(8) 548 newer than January 31, 2015, so make sure to update both world and 549 kernel before rebooting. 550 55120150217: 552 If you are running a -CURRENT kernel since r273872 (Oct 30th, 2014), 553 but before r278950, the RNG was not seeded properly. Immediately 554 upgrade the kernel to r278950 or later and regenerate any keys (e.g. 555 ssh keys or openssl keys) that were generated w/ a kernel from that 556 range. This does not affect programs that directly used /dev/random 557 or /dev/urandom. All userland uses of arc4random(3) are affected. 558 55920150210: 560 The autofs(4) ABI was changed in order to restore binary compatibility 561 with 10.1-RELEASE. The automountd(8) daemon needs to be rebuilt to work 562 with the new kernel. 563 56420150131: 565 The powerpc64 kernel has been changed to a position-independent 566 executable. This can only be booted with a new version of loader(8), 567 so make sure to update both world and kernel before rebooting. 568 56920150118: 570 Clang and llvm have been upgraded to 3.5.1 release. This is a bugfix 571 only release, no new features have been added. Please see the 20141231 572 entry below for information about prerequisites and upgrading, if you 573 are not already using 3.5.0. 574 57520150107: 576 ELF tools addr2line, elfcopy (strip), nm, size, and strings are now 577 taken from the ELF Tool Chain project rather than GNU binutils. They 578 should be drop-in replacements, with the addition of arm64 support. 579 The WITHOUT_ELFTOOLCHAIN_TOOLS= knob may be used to obtain the 580 binutils tools, if necessary. See 20150805 for updated information. 581 58220150105: 583 The default Unbound configuration now enables remote control 584 using a local socket. Users who have already enabled the 585 local_unbound service should regenerate their configuration 586 by running "service local_unbound setup" as root. 587 58820150102: 589 The GNU texinfo and GNU info pages have been removed. 590 To be able to view GNU info pages please install texinfo from ports. 591 59220141231: 593 Clang, llvm and lldb have been upgraded to 3.5.0 release. 594 595 As of this release, a prerequisite for building clang, llvm and lldb is 596 a C++11 capable compiler and C++11 standard library. This means that to 597 be able to successfully build the cross-tools stage of buildworld, with 598 clang as the bootstrap compiler, your system compiler or cross compiler 599 should either be clang 3.3 or later, or gcc 4.8 or later, and your 600 system C++ library should be libc++, or libdstdc++ from gcc 4.8 or 601 later. 602 603 On any standard FreeBSD 10.x or 11.x installation, where clang and 604 libc++ are on by default (that is, on x86 or arm), this should work out 605 of the box. 606 607 On 9.x installations where clang is enabled by default, e.g. on x86 and 608 powerpc, libc++ will not be enabled by default, so libc++ should be 609 built (with clang) and installed first. If both clang and libc++ are 610 missing, build clang first, then use it to build libc++. 611 612 On 8.x and earlier installations, upgrade to 9.x first, and then follow 613 the instructions for 9.x above. 614 615 Sparc64 and mips users are unaffected, as they still use gcc 4.2.1 by 616 default, and do not build clang. 617 618 Many embedded systems are resource constrained, and will not be able to 619 build clang in a reasonable time, or in some cases at all. In those 620 cases, cross building bootable systems on amd64 is a workaround. 621 622 This new version of clang introduces a number of new warnings, of which 623 the following are most likely to appear: 624 625 -Wabsolute-value 626 627 This warns in two cases, for both C and C++: 628 * When the code is trying to take the absolute value of an unsigned 629 quantity, which is effectively a no-op, and almost never what was 630 intended. The code should be fixed, if at all possible. If you are 631 sure that the unsigned quantity can be safely cast to signed, without 632 loss of information or undefined behavior, you can add an explicit 633 cast, or disable the warning. 634 635 * When the code is trying to take an absolute value, but the called 636 abs() variant is for the wrong type, which can lead to truncation. 637 If you want to disable the warning instead of fixing the code, please 638 make sure that truncation will not occur, or it might lead to unwanted 639 side-effects. 640 641 -Wtautological-undefined-compare and 642 -Wundefined-bool-conversion 643 644 These warn when C++ code is trying to compare 'this' against NULL, while 645 'this' should never be NULL in well-defined C++ code. However, there is 646 some legacy (pre C++11) code out there, which actively abuses this 647 feature, which was less strictly defined in previous C++ versions. 648 649 Squid and openjdk do this, for example. The warning can be turned off 650 for C++98 and earlier, but compiling the code in C++11 mode might result 651 in unexpected behavior; for example, the parts of the program that are 652 unreachable could be optimized away. 653 65420141222: 655 The old NFS client and server (kernel options NFSCLIENT, NFSSERVER) 656 kernel sources have been removed. The .h files remain, since some 657 utilities include them. This will need to be fixed later. 658 If "mount -t oldnfs ..." is attempted, it will fail. 659 If the "-o" option on mountd(8), nfsd(8) or nfsstat(1) is used, 660 the utilities will report errors. 661 66220141121: 663 The handling of LOCAL_LIB_DIRS has been altered to skip addition of 664 directories to top level SUBDIR variable when their parent 665 directory is included in LOCAL_DIRS. Users with build systems with 666 such hierarchies and without SUBDIR entries in the parent 667 directory Makefiles should add them or add the directories to 668 LOCAL_DIRS. 669 67020141109: 671 faith(4) and faithd(8) have been removed from the base system. Faith 672 has been obsolete for a very long time. 673 67420141104: 675 vt(4), the new console driver, is enabled by default. It brings 676 support for Unicode and double-width characters, as well as 677 support for UEFI and integration with the KMS kernel video 678 drivers. 679 680 You may need to update your console settings in /etc/rc.conf, 681 most probably the keymap. During boot, /etc/rc.d/syscons will 682 indicate what you need to do. 683 684 vt(4) still has issues and lacks some features compared to 685 syscons(4). See the wiki for up-to-date information: 686 https://wiki.freebsd.org/Newcons 687 688 If you want to keep using syscons(4), you can do so by adding 689 the following line to /boot/loader.conf: 690 kern.vty=sc 691 69220141102: 693 pjdfstest has been integrated into kyua as an opt-in test suite. 694 Please see share/doc/pjdfstest/README for more details on how to 695 execute it. 696 69720141009: 698 gperf has been removed from the base system for architectures 699 that use clang. Ports that require gperf will obtain it from the 700 devel/gperf port. 701 70220140923: 703 pjdfstest has been moved from tools/regression/pjdfstest to 704 contrib/pjdfstest . 705 70620140922: 707 At svn r271982, The default linux compat kernel ABI has been adjusted 708 to 2.6.18 in support of the linux-c6 compat ports infrastructure 709 update. If you wish to continue using the linux-f10 compat ports, 710 add compat.linux.osrelease=2.6.16 to your local sysctl.conf. Users are 711 encouraged to update their linux-compat packages to linux-c6 during 712 their next update cycle. 713 71420140729: 715 The ofwfb driver, used to provide a graphics console on PowerPC when 716 using vt(4), no longer allows mmap() of all physical memory. This 717 will prevent Xorg on PowerPC with some ATI graphics cards from 718 initializing properly unless x11-servers/xorg-server is updated to 719 1.12.4_8 or newer. 720 72120140723: 722 The xdev targets have been converted to using TARGET and 723 TARGET_ARCH instead of XDEV and XDEV_ARCH. 724 72520140719: 726 The default unbound configuration has been modified to address 727 issues with reverse lookups on networks that use private 728 address ranges. If you use the local_unbound service, run 729 "service local_unbound setup" as root to regenerate your 730 configuration, then "service local_unbound reload" to load the 731 new configuration. 732 73320140709: 734 The GNU texinfo and GNU info pages are not built and installed 735 anymore, WITH_INFO knob has been added to allow to built and install 736 them again. 737 UPDATE: see 20150102 entry on texinfo's removal 738 73920140708: 740 The GNU readline library is now an INTERNALLIB - that is, it is 741 statically linked into consumers (GDB and variants) in the base 742 system, and the shared library is no longer installed. The 743 devel/readline port is available for third party software that 744 requires readline. 745 74620140702: 747 The Itanium architecture (ia64) has been removed from the list of 748 known architectures. This is the first step in the removal of the 749 architecture. 750 75120140701: 752 Commit r268115 has added NFSv4.1 server support, merged from 753 projects/nfsv4.1-server. Since this includes changes to the 754 internal interfaces between the NFS related modules, a full 755 build of the kernel and modules will be necessary. 756 __FreeBSD_version has been bumped. 757 75820140629: 759 The WITHOUT_VT_SUPPORT kernel config knob has been renamed 760 WITHOUT_VT. (The other _SUPPORT knobs have a consistent meaning 761 which differs from the behaviour controlled by this knob.) 762 76320140619: 764 Maximal length of the serial number in CTL was increased from 16 to 765 64 chars, that breaks ABI. All CTL-related tools, such as ctladm 766 and ctld, need to be rebuilt to work with a new kernel. 767 76820140606: 769 The libatf-c and libatf-c++ major versions were downgraded to 0 and 770 1 respectively to match the upstream numbers. They were out of 771 sync because, when they were originally added to FreeBSD, the 772 upstream versions were not respected. These libraries are private 773 and not yet built by default, so renumbering them should be a 774 non-issue. However, unclean source trees will yield broken test 775 programs once the operator executes "make delete-old-libs" after a 776 "make installworld". 777 778 Additionally, the atf-sh binary was made private by moving it into 779 /usr/libexec/. Already-built shell test programs will keep the 780 path to the old binary so they will break after "make delete-old" 781 is run. 782 783 If you are using WITH_TESTS=yes (not the default), wipe the object 784 tree and rebuild from scratch to prevent spurious test failures. 785 This is only needed once: the misnumbered libraries and misplaced 786 binaries have been added to OptionalObsoleteFiles.inc so they will 787 be removed during a clean upgrade. 788 78920140512: 790 Clang and llvm have been upgraded to 3.4.1 release. 791 79220140508: 793 We bogusly installed src.opts.mk in /usr/share/mk. This file should 794 be removed to avoid issues in the future (and has been added to 795 ObsoleteFiles.inc). 796 79720140505: 798 /etc/src.conf now affects only builds of the FreeBSD src tree. In the 799 past, it affected all builds that used the bsd.*.mk files. The old 800 behavior was a bug, but people may have relied upon it. To get this 801 behavior back, you can .include /etc/src.conf from /etc/make.conf 802 (which is still global and isn't changed). This also changes the 803 behavior of incremental builds inside the tree of individual 804 directories. Set MAKESYSPATH to ".../share/mk" to do that. 805 Although this has survived make universe and some upgrade scenarios, 806 other upgrade scenarios may have broken. At least one form of 807 temporary breakage was fixed with MAKESYSPATH settings for buildworld 808 as well... In cases where MAKESYSPATH isn't working with this 809 setting, you'll need to set it to the full path to your tree. 810 811 One side effect of all this cleaning up is that bsd.compiler.mk 812 is no longer implicitly included by bsd.own.mk. If you wish to 813 use COMPILER_TYPE, you must now explicitly include bsd.compiler.mk 814 as well. 815 81620140430: 817 The lindev device has been removed since /dev/full has been made a 818 standard device. __FreeBSD_version has been bumped. 819 82020140424: 821 The knob WITHOUT_VI was added to the base system, which controls 822 building ex(1), vi(1), etc. Older releases of FreeBSD required ex(1) 823 in order to reorder files share/termcap and didn't build ex(1) as a 824 build tool, so building/installing with WITH_VI is highly advised for 825 build hosts for older releases. 826 827 This issue has been fixed in stable/9 and stable/10 in r277022 and 828 r276991, respectively. 829 83020140418: 831 The YES_HESIOD knob has been removed. It has been obsolete for 832 a decade. Please move to using WITH_HESIOD instead or your builds 833 will silently lack HESIOD. 834 83520140405: 836 The uart(4) driver has been changed with respect to its handling 837 of the low-level console. Previously the uart(4) driver prevented 838 any process from changing the baudrate or the CLOCAL and HUPCL 839 control flags. By removing the restrictions, operators can make 840 changes to the serial console port without having to reboot. 841 However, when getty(8) is started on the serial device that is 842 associated with the low-level console, a misconfigured terminal 843 line in /etc/ttys will now have a real impact. 844 Before upgrading the kernel, make sure that /etc/ttys has the 845 serial console device configured as 3wire without baudrate to 846 preserve the previous behaviour. E.g: 847 ttyu0 "/usr/libexec/getty 3wire" vt100 on secure 848 84920140306: 850 Support for libwrap (TCP wrappers) in rpcbind was disabled by default 851 to improve performance. To re-enable it, if needed, run rpcbind 852 with command line option -W. 853 85420140226: 855 Switched back to the GPL dtc compiler due to updates in the upstream 856 dts files not being supported by the BSDL dtc compiler. You will need 857 to rebuild your kernel toolchain to pick up the new compiler. Core dumps 858 may result while building dtb files during a kernel build if you fail 859 to do so. Set WITHOUT_GPL_DTC if you require the BSDL compiler. 860 86120140216: 862 Clang and llvm have been upgraded to 3.4 release. 863 86420140216: 865 The nve(4) driver has been removed. Please use the nfe(4) driver 866 for NVIDIA nForce MCP Ethernet adapters instead. 867 86820140212: 869 An ABI incompatibility crept into the libc++ 3.4 import in r261283. 870 This could cause certain C++ applications using shared libraries built 871 against the previous version of libc++ to crash. The incompatibility 872 has now been fixed, but any C++ applications or shared libraries built 873 between r261283 and r261801 should be recompiled. 874 87520140204: 876 OpenSSH will now ignore errors caused by kernel lacking of Capsicum 877 capability mode support. Please note that enabling the feature in 878 kernel is still highly recommended. 879 88020140131: 881 OpenSSH is now built with sandbox support, and will use sandbox as 882 the default privilege separation method. This requires Capsicum 883 capability mode support in kernel. 884 88520140128: 886 The libelf and libdwarf libraries have been updated to newer 887 versions from upstream. Shared library version numbers for 888 these two libraries were bumped. Any ports or binaries 889 requiring these two libraries should be recompiled. 890 __FreeBSD_version is bumped to 1100006. 891 89220140110: 893 If a Makefile in a tests/ directory was auto-generating a Kyuafile 894 instead of providing an explicit one, this would prevent such 895 Makefile from providing its own Kyuafile in the future during 896 NO_CLEAN builds. This has been fixed in the Makefiles but manual 897 intervention is needed to clean an objdir if you use NO_CLEAN: 898 # find /usr/obj -name Kyuafile | xargs rm -f 899 90020131213: 901 The behavior of gss_pseudo_random() for the krb5 mechanism 902 has changed, for applications requesting a longer random string 903 than produced by the underlying enctype's pseudo-random() function. 904 In particular, the random string produced from a session key of 905 enctype aes256-cts-hmac-sha1-96 or aes256-cts-hmac-sha1-96 will 906 be different at the 17th octet and later, after this change. 907 The counter used in the PRF+ construction is now encoded as a 908 big-endian integer in accordance with RFC 4402. 909 __FreeBSD_version is bumped to 1100004. 910 91120131108: 912 The WITHOUT_ATF build knob has been removed and its functionality 913 has been subsumed into the more generic WITHOUT_TESTS. If you were 914 using the former to disable the build of the ATF libraries, you 915 should change your settings to use the latter. 916 91720131025: 918 The default version of mtree is nmtree which is obtained from 919 NetBSD. The output is generally the same, but may vary 920 slightly. If you found you need identical output adding 921 "-F freebsd9" to the command line should do the trick. For the 922 time being, the old mtree is available as fmtree. 923 92420131014: 925 libbsdyml has been renamed to libyaml and moved to /usr/lib/private. 926 This will break ports-mgmt/pkg. Rebuild the port, or upgrade to pkg 927 1.1.4_8 and verify bsdyml not linked in, before running "make 928 delete-old-libs": 929 # make -C /usr/ports/ports-mgmt/pkg build deinstall install clean 930 or 931 # pkg install pkg; ldd /usr/local/sbin/pkg | grep bsdyml 932 93320131010: 934 The stable/10 branch has been created in subversion from head 935 revision r256279. 936 93720131010: 938 The rc.d/jail script has been updated to support jail(8) 939 configuration file. The "jail_<jname>_*" rc.conf(5) variables 940 for per-jail configuration are automatically converted to 941 /var/run/jail.<jname>.conf before the jail(8) utility is invoked. 942 This is transparently backward compatible. See below about some 943 incompatibilities and rc.conf(5) manual page for more details. 944 945 These variables are now deprecated in favor of jail(8) configuration 946 file. One can use "rc.d/jail config <jname>" command to generate 947 a jail(8) configuration file in /var/run/jail.<jname>.conf without 948 running the jail(8) utility. The default pathname of the 949 configuration file is /etc/jail.conf and can be specified by 950 using $jail_conf or $jail_<jname>_conf variables. 951 952 Please note that jail_devfs_ruleset accepts an integer at 953 this moment. Please consider to rewrite the ruleset name 954 with an integer. 955 95620130930: 957 BIND has been removed from the base system. If all you need 958 is a local resolver, simply enable and start the local_unbound 959 service instead. Otherwise, several versions of BIND are 960 available in the ports tree. The dns/bind99 port is one example. 961 962 With this change, nslookup(1) and dig(1) are no longer in the base 963 system. Users should instead use host(1) and drill(1) which are 964 in the base system. Alternatively, nslookup and dig can 965 be obtained by installing the dns/bind-tools port. 966 96720130916: 968 With the addition of unbound(8), a new unbound user is now 969 required during installworld. "mergemaster -p" can be used to 970 add the user prior to installworld, as documented in the handbook. 971 97220130911: 973 OpenSSH is now built with DNSSEC support, and will by default 974 silently trust signed SSHFP records. This can be controlled with 975 the VerifyHostKeyDNS client configuration setting. DNSSEC support 976 can be disabled entirely with the WITHOUT_LDNS option in src.conf. 977 97820130906: 979 The GNU Compiler Collection and C++ standard library (libstdc++) 980 are no longer built by default on platforms where clang is the system 981 compiler. You can enable them with the WITH_GCC and WITH_GNUCXX 982 options in src.conf. 983 98420130905: 985 The PROCDESC kernel option is now part of the GENERIC kernel 986 configuration and is required for the rwhod(8) to work. 987 If you are using custom kernel configuration, you should include 988 'options PROCDESC'. 989 99020130905: 991 The API and ABI related to the Capsicum framework was modified 992 in backward incompatible way. The userland libraries and programs 993 have to be recompiled to work with the new kernel. This includes the 994 following libraries and programs, but the whole buildworld is 995 advised: libc, libprocstat, dhclient, tcpdump, hastd, hastctl, 996 kdump, procstat, rwho, rwhod, uniq. 997 99820130903: 999 AES-NI intrinsic support has been added to gcc. The AES-NI module 1000 has been updated to use this support. A new gcc is required to build 1001 the aesni module on both i386 and amd64. 1002 100320130821: 1004 The PADLOCK_RNG and RDRAND_RNG kernel options are now devices. 1005 Thus "device padlock_rng" and "device rdrand_rng" should be 1006 used instead of "options PADLOCK_RNG" & "options RDRAND_RNG". 1007 100820130813: 1009 WITH_ICONV has been split into two feature sets. WITH_ICONV now 1010 enables just the iconv* functionality and is now on by default. 1011 WITH_LIBICONV_COMPAT enables the libiconv api and link time 1012 compatibility. Set WITHOUT_ICONV to build the old way. 1013 If you have been using WITH_ICONV before, you will very likely 1014 need to turn on WITH_LIBICONV_COMPAT. 1015 101620130806: 1017 INVARIANTS option now enables DEBUG for code with OpenSolaris and 1018 Illumos origin, including ZFS. If you have INVARIANTS in your 1019 kernel configuration, then there is no need to set DEBUG or ZFS_DEBUG 1020 explicitly. 1021 DEBUG used to enable witness(9) tracking of OpenSolaris (mostly ZFS) 1022 locks if WITNESS option was set. Because that generated a lot of 1023 witness(9) reports and all of them were believed to be false 1024 positives, this is no longer done. New option OPENSOLARIS_WITNESS 1025 can be used to achieve the previous behavior. 1026 102720130806: 1028 Timer values in IPv6 data structures now use time_uptime instead 1029 of time_second. Although this is not a user-visible functional 1030 change, userland utilities which directly use them---ndp(8), 1031 rtadvd(8), and rtsold(8) in the base system---need to be updated 1032 to r253970 or later. 1033 103420130802: 1035 find -delete can now delete the pathnames given as arguments, 1036 instead of only files found below them or if the pathname did 1037 not contain any slashes. Formerly, the following error message 1038 would result: 1039 1040 find: -delete: <path>: relative path potentially not safe 1041 1042 Deleting the pathnames given as arguments can be prevented 1043 without error messages using -mindepth 1 or by changing 1044 directory and passing "." as argument to find. This works in the 1045 old as well as the new version of find. 1046 104720130726: 1048 Behavior of devfs rules path matching has been changed. 1049 Pattern is now always matched against fully qualified devfs 1050 path and slash characters must be explicitly matched by 1051 slashes in pattern (FNM_PATHNAME). Rulesets involving devfs 1052 subdirectories must be reviewed. 1053 105420130716: 1055 The default ARM ABI has changed to the ARM EABI. The old ABI is 1056 incompatible with the ARM EABI and all programs and modules will 1057 need to be rebuilt to work with a new kernel. 1058 1059 To keep using the old ABI ensure the WITHOUT_ARM_EABI knob is set. 1060 1061 NOTE: Support for the old ABI will be removed in the future and 1062 users are advised to upgrade. 1063 106420130709: 1065 pkg_install has been disconnected from the build if you really need it 1066 you should add WITH_PKGTOOLS in your src.conf(5). 1067 106820130709: 1069 Most of network statistics structures were changed to be able 1070 keep 64-bits counters. Thus all tools, that work with networking 1071 statistics, must be rebuilt (netstat(1), bsnmpd(1), etc.) 1072 107320130618: 1074 Fix a bug that allowed a tracing process (e.g. gdb) to write 1075 to a memory-mapped file in the traced process's address space 1076 even if neither the traced process nor the tracing process had 1077 write access to that file. 1078 107920130615: 1080 CVS has been removed from the base system. An exact copy 1081 of the code is available from the devel/cvs port. 1082 108320130613: 1084 Some people report the following error after the switch to bmake: 1085 1086 make: illegal option -- J 1087 usage: make [-BPSXeiknpqrstv] [-C directory] [-D variable] 1088 ... 1089 *** [buildworld] Error code 2 1090 1091 this likely due to an old instance of make in 1092 ${MAKEPATH} (${MAKEOBJDIRPREFIX}${.CURDIR}/make.${MACHINE}) 1093 which src/Makefile will use that blindly, if it exists, so if 1094 you see the above error: 1095 1096 rm -rf `make -V MAKEPATH` 1097 1098 should resolve it. 1099 110020130516: 1101 Use bmake by default. 1102 Whereas before one could choose to build with bmake via 1103 -DWITH_BMAKE one must now use -DWITHOUT_BMAKE to use the old 1104 make. The goal is to remove these knobs for 10-RELEASE. 1105 1106 It is worth noting that bmake (like gmake) treats the command 1107 line as the unit of failure, rather than statements within the 1108 command line. Thus '(cd some/where && dosomething)' is safer 1109 than 'cd some/where; dosomething'. The '()' allows consistent 1110 behavior in parallel build. 1111 111220130429: 1113 Fix a bug that allows NFS clients to issue READDIR on files. 1114 111520130426: 1116 The WITHOUT_IDEA option has been removed because 1117 the IDEA patent expired. 1118 111920130426: 1120 The sysctl which controls TRIM support under ZFS has been renamed 1121 from vfs.zfs.trim_disable -> vfs.zfs.trim.enabled and has been 1122 enabled by default. 1123 112420130425: 1125 The mergemaster command now uses the default MAKEOBJDIRPREFIX 1126 rather than creating it's own in the temporary directory in 1127 order allow access to bootstrapped versions of tools such as 1128 install and mtree. When upgrading from version of FreeBSD where 1129 the install command does not support -l, you will need to 1130 install a new mergemaster command if mergemaster -p is required. 1131 This can be accomplished with the command (cd src/usr.sbin/mergemaster 1132 && make install). 1133 113420130404: 1135 Legacy ATA stack, disabled and replaced by new CAM-based one since 1136 FreeBSD 9.0, completely removed from the sources. Kernel modules 1137 atadisk and atapi*, user-level tools atacontrol and burncd are 1138 removed. Kernel option `options ATA_CAM` is now permanently enabled 1139 and removed. 1140 114120130319: 1142 SOCK_CLOEXEC and SOCK_NONBLOCK flags have been added to socket(2) 1143 and socketpair(2). Software, in particular Kerberos, may 1144 automatically detect and use these during building. The resulting 1145 binaries will not work on older kernels. 1146 114720130308: 1148 CTL_DISABLE has also been added to the sparc64 GENERIC (for further 1149 information, see the respective 20130304 entry). 1150 115120130304: 1152 Recent commits to callout(9) changed the size of struct callout, 1153 so the KBI is probably heavily disturbed. Also, some functions 1154 in callout(9)/sleep(9)/sleepqueue(9)/condvar(9) KPIs were replaced 1155 by macros. Every kernel module using it won't load, so rebuild 1156 is requested. 1157 1158 The ctl device has been re-enabled in GENERIC for i386 and amd64, 1159 but does not initialize by default (because of the new CTL_DISABLE 1160 option) to save memory. To re-enable it, remove the CTL_DISABLE 1161 option from the kernel config file or set kern.cam.ctl.disable=0 1162 in /boot/loader.conf. 1163 116420130301: 1165 The ctl device has been disabled in GENERIC for i386 and amd64. 1166 This was done due to the extra memory being allocated at system 1167 initialisation time by the ctl driver which was only used if 1168 a CAM target device was created. This makes a FreeBSD system 1169 unusable on 128MB or less of RAM. 1170 117120130208: 1172 A new compression method (lz4) has been merged to -HEAD. Please 1173 refer to zpool-features(7) for more information. 1174 1175 Please refer to the "ZFS notes" section of this file for information 1176 on upgrading boot ZFS pools. 1177 117820130129: 1179 A BSD-licensed patch(1) variant has been added and is installed 1180 as bsdpatch, being the GNU version the default patch. 1181 To inverse the logic and use the BSD-licensed one as default, 1182 while having the GNU version installed as gnupatch, rebuild 1183 and install world with the WITH_BSD_PATCH knob set. 1184 118520130121: 1186 Due to the use of the new -l option to install(1) during build 1187 and install, you must take care not to directly set the INSTALL 1188 make variable in your /etc/make.conf, /etc/src.conf, or on the 1189 command line. If you wish to use the -C flag for all installs 1190 you may be able to add INSTALL+=-C to /etc/make.conf or 1191 /etc/src.conf. 1192 119320130118: 1194 The install(1) option -M has changed meaning and now takes an 1195 argument that is a file or path to append logs to. In the 1196 unlikely event that -M was the last option on the command line 1197 and the command line contained at least two files and a target 1198 directory the first file will have logs appended to it. The -M 1199 option served little practical purpose in the last decade so its 1200 use is expected to be extremely rare. 1201 120220121223: 1203 After switching to Clang as the default compiler some users of ZFS 1204 on i386 systems started to experience stack overflow kernel panics. 1205 Please consider using 'options KSTACK_PAGES=4' in such configurations. 1206 120720121222: 1208 GEOM_LABEL now mangles label names read from file system metadata. 1209 Mangling affect labels containing spaces, non-printable characters, 1210 '%' or '"'. Device names in /etc/fstab and other places may need to 1211 be updated. 1212 121320121217: 1214 By default, only the 10 most recent kernel dumps will be saved. To 1215 restore the previous behaviour (no limit on the number of kernel dumps 1216 stored in the dump directory) add the following line to /etc/rc.conf: 1217 1218 savecore_flags="" 1219 122020121201: 1221 With the addition of auditdistd(8), a new auditdistd user is now 1222 required during installworld. "mergemaster -p" can be used to 1223 add the user prior to installworld, as documented in the handbook. 1224 122520121117: 1226 The sin6_scope_id member variable in struct sockaddr_in6 is now 1227 filled by the kernel before passing the structure to the userland via 1228 sysctl or routing socket. This means the KAME-specific embedded scope 1229 id in sin6_addr.s6_addr[2] is always cleared in userland application. 1230 This behavior can be controlled by net.inet6.ip6.deembed_scopeid. 1231 __FreeBSD_version is bumped to 1000025. 1232 123320121105: 1234 On i386 and amd64 systems WITH_CLANG_IS_CC is now the default. 1235 This means that the world and kernel will be compiled with clang 1236 and that clang will be installed as /usr/bin/cc, /usr/bin/c++, 1237 and /usr/bin/cpp. To disable this behavior and revert to building 1238 with gcc, compile with WITHOUT_CLANG_IS_CC. Really old versions 1239 of current may need to bootstrap WITHOUT_CLANG first if the clang 1240 build fails (its compatibility window doesn't extend to the 9 stable 1241 branch point). 1242 124320121102: 1244 The IPFIREWALL_FORWARD kernel option has been removed. Its 1245 functionality now turned on by default. 1246 124720121023: 1248 The ZERO_COPY_SOCKET kernel option has been removed and 1249 split into SOCKET_SEND_COW and SOCKET_RECV_PFLIP. 1250 NB: SOCKET_SEND_COW uses the VM page based copy-on-write 1251 mechanism which is not safe and may result in kernel crashes. 1252 NB: The SOCKET_RECV_PFLIP mechanism is useless as no current 1253 driver supports disposeable external page sized mbuf storage. 1254 Proper replacements for both zero-copy mechanisms are under 1255 consideration and will eventually lead to complete removal 1256 of the two kernel options. 1257 125820121023: 1259 The IPv4 network stack has been converted to network byte 1260 order. The following modules need to be recompiled together 1261 with kernel: carp(4), divert(4), gif(4), siftr(4), gre(4), 1262 pf(4), ipfw(4), ng_ipfw(4), stf(4). 1263 126420121022: 1265 Support for non-MPSAFE filesystems was removed from VFS. The 1266 VFS_VERSION was bumped, all filesystem modules shall be 1267 recompiled. 1268 126920121018: 1270 All the non-MPSAFE filesystems have been disconnected from 1271 the build. The full list includes: codafs, hpfs, ntfs, nwfs, 1272 portalfs, smbfs, xfs. 1273 127420121016: 1275 The interface cloning API and ABI has changed. The following 1276 modules need to be recompiled together with kernel: 1277 ipfw(4), pfsync(4), pflog(4), usb(4), wlan(4), stf(4), 1278 vlan(4), disc(4), edsc(4), if_bridge(4), gif(4), tap(4), 1279 faith(4), epair(4), enc(4), tun(4), if_lagg(4), gre(4). 1280 128120121015: 1282 The sdhci driver was split in two parts: sdhci (generic SD Host 1283 Controller logic) and sdhci_pci (actual hardware driver). 1284 No kernel config modifications are required, but if you 1285 load sdhc as a module you must switch to sdhci_pci instead. 1286 128720121014: 1288 Import the FUSE kernel and userland support into base system. 1289 129020121013: 1291 The GNU sort(1) program has been removed since the BSD-licensed 1292 sort(1) has been the default for quite some time and no serious 1293 problems have been reported. The corresponding WITH_GNU_SORT 1294 knob has also gone. 1295 129620121006: 1297 The pfil(9) API/ABI for AF_INET family has been changed. Packet 1298 filtering modules: pf(4), ipfw(4), ipfilter(4) need to be recompiled 1299 with new kernel. 1300 130120121001: 1302 The net80211(4) ABI has been changed to allow for improved driver 1303 PS-POLL and power-save support. All wireless drivers need to be 1304 recompiled to work with the new kernel. 1305 130620120913: 1307 The random(4) support for the VIA hardware random number 1308 generator (`PADLOCK') is no longer enabled unconditionally. 1309 Add the padlock_rng device in the custom kernel config if 1310 needed. The GENERIC kernels on i386 and amd64 do include the 1311 device, so the change only affects the custom kernel 1312 configurations. 1313 131420120908: 1315 The pf(4) packet filter ABI has been changed. pfctl(8) and 1316 snmp_pf module need to be recompiled to work with new kernel. 1317 131820120828: 1319 A new ZFS feature flag "com.delphix:empty_bpobj" has been merged 1320 to -HEAD. Pools that have empty_bpobj in active state can not be 1321 imported read-write with ZFS implementations that do not support 1322 this feature. For more information read the zpool-features(5) 1323 manual page. 1324 132520120727: 1326 The sparc64 ZFS loader has been changed to no longer try to auto- 1327 detect ZFS providers based on diskN aliases but now requires these 1328 to be explicitly listed in the OFW boot-device environment variable. 1329 133020120712: 1331 The OpenSSL has been upgraded to 1.0.1c. Any binaries requiring 1332 libcrypto.so.6 or libssl.so.6 must be recompiled. Also, there are 1333 configuration changes. Make sure to merge /etc/ssl/openssl.cnf. 1334 133520120712: 1336 The following sysctls and tunables have been renamed for consistency 1337 with other variables: 1338 kern.cam.da.da_send_ordered -> kern.cam.da.send_ordered 1339 kern.cam.ada.ada_send_ordered -> kern.cam.ada.send_ordered 1340 134120120628: 1342 The sort utility has been replaced with BSD sort. For now, GNU sort 1343 is also available as "gnusort" or the default can be set back to 1344 GNU sort by setting WITH_GNU_SORT. In this case, BSD sort will be 1345 installed as "bsdsort". 1346 134720120611: 1348 A new version of ZFS (pool version 5000) has been merged to -HEAD. 1349 Starting with this version the old system of ZFS pool versioning 1350 is superseded by "feature flags". This concept enables forward 1351 compatibility against certain future changes in functionality of ZFS 1352 pools. The first read-only compatible "feature flag" for ZFS pools 1353 is named "com.delphix:async_destroy". For more information 1354 read the new zpool-features(5) manual page. 1355 Please refer to the "ZFS notes" section of this file for information 1356 on upgrading boot ZFS pools. 1357 135820120417: 1359 The malloc(3) implementation embedded in libc now uses sources imported 1360 as contrib/jemalloc. The most disruptive API change is to 1361 /etc/malloc.conf. If your system has an old-style /etc/malloc.conf, 1362 delete it prior to installworld, and optionally re-create it using the 1363 new format after rebooting. See malloc.conf(5) for details 1364 (specifically the TUNING section and the "opt.*" entries in the MALLCTL 1365 NAMESPACE section). 1366 136720120328: 1368 Big-endian MIPS TARGET_ARCH values no longer end in "eb". mips64eb 1369 is now spelled mips64. mipsn32eb is now spelled mipsn32. mipseb is 1370 now spelled mips. This is to aid compatibility with third-party 1371 software that expects this naming scheme in uname(3). Little-endian 1372 settings are unchanged. If you are updating a big-endian mips64 machine 1373 from before this change, you may need to set MACHINE_ARCH=mips64 in 1374 your environment before the new build system will recognize your machine. 1375 137620120306: 1377 Disable by default the option VFS_ALLOW_NONMPSAFE for all supported 1378 platforms. 1379 138020120229: 1381 Now unix domain sockets behave "as expected" on nullfs(5). Previously 1382 nullfs(5) did not pass through all behaviours to the underlying layer, 1383 as a result if we bound to a socket on the lower layer we could connect 1384 only to the lower path; if we bound to the upper layer we could connect 1385 only to the upper path. The new behavior is one can connect to both the 1386 lower and the upper paths regardless what layer path one binds to. 1387 138820120211: 1389 The getifaddrs upgrade path broken with 20111215 has been restored. 1390 If you have upgraded in between 20111215 and 20120209 you need to 1391 recompile libc again with your kernel. You still need to recompile 1392 world to be able to configure CARP but this restriction already 1393 comes from 20111215. 1394 139520120114: 1396 The set_rcvar() function has been removed from /etc/rc.subr. All 1397 base and ports rc.d scripts have been updated, so if you have a 1398 port installed with a script in /usr/local/etc/rc.d you can either 1399 hand-edit the rcvar= line, or reinstall the port. 1400 1401 An easy way to handle the mass-update of /etc/rc.d: 1402 rm /etc/rc.d/* && mergemaster -i 1403 140420120109: 1405 panic(9) now stops other CPUs in the SMP systems, disables interrupts 1406 on the current CPU and prevents other threads from running. 1407 This behavior can be reverted using the kern.stop_scheduler_on_panic 1408 tunable/sysctl. 1409 The new behavior can be incompatible with kern.sync_on_panic. 1410 141120111215: 1412 The carp(4) facility has been changed significantly. Configuration 1413 of the CARP protocol via ifconfig(8) has changed, as well as format 1414 of CARP events submitted to devd(8) has changed. See manual pages 1415 for more information. The arpbalance feature of carp(4) is currently 1416 not supported anymore. 1417 1418 Size of struct in_aliasreq, struct in6_aliasreq has changed. User 1419 utilities using SIOCAIFADDR, SIOCAIFADDR_IN6, e.g. ifconfig(8), 1420 need to be recompiled. 1421 142220111122: 1423 The acpi_wmi(4) status device /dev/wmistat has been renamed to 1424 /dev/wmistat0. 1425 142620111108: 1427 The option VFS_ALLOW_NONMPSAFE option has been added in order to 1428 explicitely support non-MPSAFE filesystems. 1429 It is on by default for all supported platform at this present 1430 time. 1431 143220111101: 1433 The broken amd(4) driver has been replaced with esp(4) in the amd64, 1434 i386 and pc98 GENERIC kernel configuration files. 1435 143620110930: 1437 sysinstall has been removed 1438 143920110923: 1440 The stable/9 branch created in subversion. This corresponds to the 1441 RELENG_9 branch in CVS. 1442 1443COMMON ITEMS: 1444 1445 General Notes 1446 ------------- 1447 Avoid using make -j when upgrading. While generally safe, there are 1448 sometimes problems using -j to upgrade. If your upgrade fails with 1449 -j, please try again without -j. From time to time in the past there 1450 have been problems using -j with buildworld and/or installworld. This 1451 is especially true when upgrading between "distant" versions (eg one 1452 that cross a major release boundary or several minor releases, or when 1453 several months have passed on the -current branch). 1454 1455 Sometimes, obscure build problems are the result of environment 1456 poisoning. This can happen because the make utility reads its 1457 environment when searching for values for global variables. To run 1458 your build attempts in an "environmental clean room", prefix all make 1459 commands with 'env -i '. See the env(1) manual page for more details. 1460 1461 When upgrading from one major version to another it is generally best 1462 to upgrade to the latest code in the currently installed branch first, 1463 then do an upgrade to the new branch. This is the best-tested upgrade 1464 path, and has the highest probability of being successful. Please try 1465 this approach before reporting problems with a major version upgrade. 1466 1467 When upgrading a live system, having a root shell around before 1468 installing anything can help undo problems. Not having a root shell 1469 around can lead to problems if pam has changed too much from your 1470 starting point to allow continued authentication after the upgrade. 1471 1472 This file should be read as a log of events. When a later event changes 1473 information of a prior event, the prior event should not be deleted. 1474 Instead, a pointer to the entry with the new information should be 1475 placed in the old entry. Readers of this file should also sanity check 1476 older entries before relying on them blindly. Authors of new entries 1477 should write them with this in mind. 1478 1479 ZFS notes 1480 --------- 1481 When upgrading the boot ZFS pool to a new version, always follow 1482 these two steps: 1483 1484 1.) recompile and reinstall the ZFS boot loader and boot block 1485 (this is part of "make buildworld" and "make installworld") 1486 1487 2.) update the ZFS boot block on your boot drive 1488 1489 The following example updates the ZFS boot block on the first 1490 partition (freebsd-boot) of a GPT partitioned drive ada0: 1491 "gpart bootcode -p /boot/gptzfsboot -i 1 ada0" 1492 1493 Non-boot pools do not need these updates. 1494 1495 To build a kernel 1496 ----------------- 1497 If you are updating from a prior version of FreeBSD (even one just 1498 a few days old), you should follow this procedure. It is the most 1499 failsafe as it uses a /usr/obj tree with a fresh mini-buildworld, 1500 1501 make kernel-toolchain 1502 make -DALWAYS_CHECK_MAKE buildkernel KERNCONF=YOUR_KERNEL_HERE 1503 make -DALWAYS_CHECK_MAKE installkernel KERNCONF=YOUR_KERNEL_HERE 1504 1505 To test a kernel once 1506 --------------------- 1507 If you just want to boot a kernel once (because you are not sure 1508 if it works, or if you want to boot a known bad kernel to provide 1509 debugging information) run 1510 make installkernel KERNCONF=YOUR_KERNEL_HERE KODIR=/boot/testkernel 1511 nextboot -k testkernel 1512 1513 To just build a kernel when you know that it won't mess you up 1514 -------------------------------------------------------------- 1515 This assumes you are already running a CURRENT system. Replace 1516 ${arch} with the architecture of your machine (e.g. "i386", 1517 "arm", "amd64", "ia64", "pc98", "sparc64", "powerpc", "mips", etc). 1518 1519 cd src/sys/${arch}/conf 1520 config KERNEL_NAME_HERE 1521 cd ../compile/KERNEL_NAME_HERE 1522 make depend 1523 make 1524 make install 1525 1526 If this fails, go to the "To build a kernel" section. 1527 1528 To rebuild everything and install it on the current system. 1529 ----------------------------------------------------------- 1530 # Note: sometimes if you are running current you gotta do more than 1531 # is listed here if you are upgrading from a really old current. 1532 1533 <make sure you have good level 0 dumps> 1534 make buildworld 1535 make kernel KERNCONF=YOUR_KERNEL_HERE 1536 [1] 1537 <reboot in single user> [3] 1538 mergemaster -Fp [5] 1539 make installworld 1540 mergemaster -Fi [4] 1541 make delete-old [6] 1542 <reboot> 1543 1544 To cross-install current onto a separate partition 1545 -------------------------------------------------- 1546 # In this approach we use a separate partition to hold 1547 # current's root, 'usr', and 'var' directories. A partition 1548 # holding "/", "/usr" and "/var" should be about 2GB in 1549 # size. 1550 1551 <make sure you have good level 0 dumps> 1552 <boot into -stable> 1553 make buildworld 1554 make buildkernel KERNCONF=YOUR_KERNEL_HERE 1555 <maybe newfs current's root partition> 1556 <mount current's root partition on directory ${CURRENT_ROOT}> 1557 make installworld DESTDIR=${CURRENT_ROOT} -DDB_FROM_SRC 1558 make distribution DESTDIR=${CURRENT_ROOT} # if newfs'd 1559 make installkernel KERNCONF=YOUR_KERNEL_HERE DESTDIR=${CURRENT_ROOT} 1560 cp /etc/fstab ${CURRENT_ROOT}/etc/fstab # if newfs'd 1561 <edit ${CURRENT_ROOT}/etc/fstab to mount "/" from the correct partition> 1562 <reboot into current> 1563 <do a "native" rebuild/install as described in the previous section> 1564 <maybe install compatibility libraries from ports/misc/compat*> 1565 <reboot> 1566 1567 1568 To upgrade in-place from stable to current 1569 ---------------------------------------------- 1570 <make sure you have good level 0 dumps> 1571 make buildworld [9] 1572 make kernel KERNCONF=YOUR_KERNEL_HERE [8] 1573 [1] 1574 <reboot in single user> [3] 1575 mergemaster -Fp [5] 1576 make installworld 1577 mergemaster -Fi [4] 1578 make delete-old [6] 1579 <reboot> 1580 1581 Make sure that you've read the UPDATING file to understand the 1582 tweaks to various things you need. At this point in the life 1583 cycle of current, things change often and you are on your own 1584 to cope. The defaults can also change, so please read ALL of 1585 the UPDATING entries. 1586 1587 Also, if you are tracking -current, you must be subscribed to 1588 freebsd-current@freebsd.org. Make sure that before you update 1589 your sources that you have read and understood all the recent 1590 messages there. If in doubt, please track -stable which has 1591 much fewer pitfalls. 1592 1593 [1] If you have third party modules, such as vmware, you 1594 should disable them at this point so they don't crash your 1595 system on reboot. 1596 1597 [3] From the bootblocks, boot -s, and then do 1598 fsck -p 1599 mount -u / 1600 mount -a 1601 cd src 1602 adjkerntz -i # if CMOS is wall time 1603 Also, when doing a major release upgrade, it is required that 1604 you boot into single user mode to do the installworld. 1605 1606 [4] Note: This step is non-optional. Failure to do this step 1607 can result in a significant reduction in the functionality of the 1608 system. Attempting to do it by hand is not recommended and those 1609 that pursue this avenue should read this file carefully, as well 1610 as the archives of freebsd-current and freebsd-hackers mailing lists 1611 for potential gotchas. The -U option is also useful to consider. 1612 See mergemaster(8) for more information. 1613 1614 [5] Usually this step is a noop. However, from time to time 1615 you may need to do this if you get unknown user in the following 1616 step. It never hurts to do it all the time. You may need to 1617 install a new mergemaster (cd src/usr.sbin/mergemaster && make 1618 install) after the buildworld before this step if you last updated 1619 from current before 20130425 or from -stable before 20130430. 1620 1621 [6] This only deletes old files and directories. Old libraries 1622 can be deleted by "make delete-old-libs", but you have to make 1623 sure that no program is using those libraries anymore. 1624 1625 [8] In order to have a kernel that can run the 4.x binaries needed to 1626 do an installworld, you must include the COMPAT_FREEBSD4 option in 1627 your kernel. Failure to do so may leave you with a system that is 1628 hard to boot to recover. A similar kernel option COMPAT_FREEBSD5 is 1629 required to run the 5.x binaries on more recent kernels. And so on 1630 for COMPAT_FREEBSD6 and COMPAT_FREEBSD7. 1631 1632 Make sure that you merge any new devices from GENERIC since the 1633 last time you updated your kernel config file. 1634 1635 [9] When checking out sources, you must include the -P flag to have 1636 cvs prune empty directories. 1637 1638 If CPUTYPE is defined in your /etc/make.conf, make sure to use the 1639 "?=" instead of the "=" assignment operator, so that buildworld can 1640 override the CPUTYPE if it needs to. 1641 1642 MAKEOBJDIRPREFIX must be defined in an environment variable, and 1643 not on the command line, or in /etc/make.conf. buildworld will 1644 warn if it is improperly defined. 1645FORMAT: 1646 1647This file contains a list, in reverse chronological order, of major 1648breakages in tracking -current. It is not guaranteed to be a complete 1649list of such breakages, and only contains entries since September 23, 2011. 1650If you need to see UPDATING entries from before that date, you will need 1651to fetch an UPDATING file from an older FreeBSD release. 1652 1653Copyright information: 1654 1655Copyright 1998-2009 M.
