UPDATING revision 329140
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 1920180211: 20 The LOADER_FIREWIRE_SUPPORT build variable as been renamed to 21 WITH/OUT_LOADER_FIREWIRE. LOADER_{NO_,}GELI_SUPPORT has been renamed 22 to WITH/OUT_LOADER_GELI. 23 2420180210: 25 The geli password typed at boot is now hidden. To restore the previous 26 behavior, see geli(8) for configuration options. 27 2820180113: 29 The SW_WATCHDOG option is no longer necessary to enable the 30 hardclock-based software watchdog if no hardware watchdog is 31 configured. As before, SW_WATCHDOG will cause the software 32 watchdog to be enabled even if a hardware watchdog is configured. 33 3420180108: 35 lint(1) binaries and library are no longer built by default. To 36 enable building them, define WITH_LINT in src.conf. If you are using 37 a FreeBSD 12 or later system to build 11-stable, you may need to 38 install a lint(1) binary to use WITH_LINT. 39 4020171003: 41 When building multiple kernels using KERNCONF, non-existent KERNCONF 42 files will produce an error and buildkernel will fail. Previously 43 missing KERNCONF files silently failed giving no indication as to 44 why, only to subsequently discover during installkernel that the 45 desired kernel was never built in the first place. 46 4720170926: 48 Clang, llvm, lldb, compiler-rt and libc++ have been upgraded to 5.0.0. 49 Please see the 20141231 entry below for information about prerequisites 50 and upgrading, if you are not already using clang 3.5.0 or higher. 51 5220170822: 53 Since the switch to GPT disk labels, fsck for UFS/FFS has been 54 unable to automatically find alternate superblocks. As of r322806, 55 the information needed to find alternate superblocks has been 56 moved to the end of the area reserved for the boot block. 57 Filesystems created with a newfs of this vintage or later 58 will create the recovery information. If you have a filesystem 59 created prior to this change and wish to have a recovery block 60 created for your filesystem, you can do so by running fsck in 61 forground mode (i.e., do not use the -p or -y options). As it 62 starts, fsck will ask ``SAVE DATA TO FIND ALTERNATE SUPERBLOCKS'' 63 to which you should answer yes. 64 6520170518: 66 arm64 builds now use the base system LLD 4.0.0 linker by default, 67 instead of requiring that the aarch64-binutils port or package be 68 installed. To continue using aarch64-binutils, set 69 CROSS_BINUTILS_PREFIX=/usr/local/aarch64-freebsd/bin . 70 7120170529: 72 The ctl.ko module no longer implements the iSCSI target frontend: 73 cfiscsi.ko does instead. 74 75 If building cfiscsi.ko as a kernel module, the module can be loaded 76 via one of the following methods: 77 - `cfiscsi_load="YES"` in loader.conf(5). 78 - Add `cfiscsi` to `$kld_list` in rc.conf(5). 79 - ctladm(8)/ctld(8), when compiled with iSCSI support 80 (`WITH_ISCSI=yes` in src.conf(5)) 81 82 Please see cfiscsi(4) for more details. 83 8420170511: 85 The mmcsd.ko module now additionally depends on geom_flashmap.ko. 86 Also, mmc.ko and mmcsd.ko need to be a matching pair built from the 87 same source (previously, the dependency of mmcsd.ko on mmc.ko was 88 missing, but mmcsd.ko now will refuse to load if it is incompatible 89 with mmc.ko). 90 9120170414: 92 Binds and sends to the loopback addresses, IPv6 and IPv4, will now 93 use any explicitly assigned loopback address available in the jail 94 instead of using the first assigned address of the jail. 95 9620170413: 97 As of r316810 for ipfilter, keep frags is no longer assumed when 98 keep state is specified in a rule. r316810 aligns ipfilter with 99 documentation in man pages separating keep frags from keep state. 100 This allows keep state to specified without forcing keep frags 101 and allows keep frags to be specified independently of keep state. 102 To maintain previous behaviour, also specify keep frags with 103 keep state (as documented in ipf.conf.5). 104 10520170402: 106 Clang, llvm, lldb, compiler-rt and libc++ have been upgraded to 4.0.0. 107 Please see the 20141231 entry below for information about prerequisites 108 and upgrading, if you are not already using clang 3.5.0 or higher. 109 11020170323: 111 The code that provides support for ZFS .zfs/ directory functionality 112 has been reimplemented. It's not possible now to create a snapshot 113 by mkdir under .zfs/snapshot/. That should be the only user visible 114 change. 115 11620170319: 117 Many changes in the IPsec code have been merged from the FreeBSD-CURRENT 118 branch. The IPSEC_FILTERTUNNEL kernel option is removed in favour of 119 corresponding sysctl. The IPSEC_NAT_T kernel option is also removed, 120 and now NAT-T is supported by default. Security associations now use 121 the single namespace for SPI allocation, so if you use several manually 122 configured security associations with the same SPI, this configuration 123 needs modification. 124 12520161217: 126 Clang, llvm, lldb, compiler-rt and libc++ have been upgraded to 3.9.1. 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 13020161124: 131 Clang, llvm, lldb, compiler-rt and libc++ have been upgraded to 3.9.0. 132 Please see the 20141231 entry below for information about prerequisites 133 and upgrading, if you are not already using clang 3.5.0 or higher. 134 13520161119: 136 The layout of the pmap structure has changed for powerpc to put the pmap 137 statistics at the front for all CPU variations. libkvm(3) and all tools 138 that link against it need to be recompiled. 139 14020161030: 141 isl(4) and cyapa(4) drivers now require a new driver, 142 chromebook_platform(4), to work properly on Chromebook-class hardware. 143 On other types of hardware the drivers may need to be configured using 144 device hints. Please see the corresponding manual pages for details. 145 14620161210: 147 Relocatable object files with the extension of .So have been renamed 148 to use an extension of .pico instead. The purpose of this change is 149 to avoid a name clash with shared libraries on case-insensitive file 150 systems. On those file systems, foo.So is the same file as foo.so. 151 15220160622: 153 The libc stub for the pipe(2) system call has been replaced with 154 a wrapper that calls the pipe2(2) system call and the pipe(2) 155 system call is now only implemented by the kernels that include 156 "options COMPAT_FREEBSD10" in their config file (this is the 157 default). Users should ensure that this option is enabled in 158 their kernel or upgrade userspace to r302092 before upgrading their 159 kernel. 160 16120160527: 162 CAM will now strip leading spaces from SCSI disks' serial numbers. 163 This will effect users who create UFS filesystems on SCSI disks using 164 those disk's diskid device nodes. For example, if /etc/fstab 165 previously contained a line like 166 "/dev/diskid/DISK-%20%20%20%20%20%20%20ABCDEFG0123456", you should 167 change it to "/dev/diskid/DISK-ABCDEFG0123456". Users of geom 168 transforms like gmirror may also be affected. ZFS users should 169 generally be fine. 170 17120160523: 172 The bitstring(3) API has been updated with new functionality and 173 improved performance. But it is binary-incompatible with the old API. 174 Objects built with the new headers may not be linked against objects 175 built with the old headers. 176 17720160520: 178 The brk and sbrk functions have been removed from libc on arm64. 179 Binutils from ports has been updated to not link to these 180 functions and should be updated to the latest version before 181 installing a new libc. 182 18320160517: 184 The armv6 port now defaults to hard float ABI. Limited support 185 for running both hardfloat and soft float on the same system 186 is available using the libraries installed with -DWITH_LIBSOFT. 187 This has only been tested as an upgrade path for installworld 188 and packages may fail or need manual intervention to run. New 189 packages will be needed. 190 191 To update an existing self-hosted armv6hf system, you must add 192 TARGET_ARCH=armv6 on the make command line for both the build 193 and the install steps. 194 19520160510: 196 Kernel modules compiled outside of a kernel build now default to 197 installing to /boot/modules instead of /boot/kernel. Many kernel 198 modules built this way (such as those in ports) already overrode 199 KMODDIR explicitly to install into /boot/modules. However, 200 manually building and installing a module from /sys/modules will 201 now install to /boot/modules instead of /boot/kernel. 202 20320160414: 204 The CAM I/O scheduler has been committed to the kernel. There should be 205 no user visible impact. This does enable NCQ Trim on ada SSDs. While the 206 list of known rogues that claim support for this but actually corrupt 207 data is believed to be complete, be on the lookout for data 208 corruption. The known rogue list is believed to be complete: 209 210 o Crucial MX100, M550 drives with MU01 firmware. 211 o Micron M510 and M550 drives with MU01 firmware. 212 o Micron M500 prior to MU07 firmware 213 o Samsung 830, 840, and 850 all firmwares 214 o FCCT M500 all firmwares 215 216 Crucial has firmware http://www.crucial.com/usa/en/support-ssd-firmware 217 with working NCQ TRIM. For Micron branded drives, see your sales rep for 218 updated firmware. Black listed drives will work correctly because these 219 drives work correctly so long as no NCQ TRIMs are sent to them. Given 220 this list is the same as found in Linux, it's believed there are no 221 other rogues in the market place. All other models from the above 222 vendors work. 223 224 To be safe, if you are at all concerned, you can quirk each of your 225 drives to prevent NCQ from being sent by setting: 226 kern.cam.ada.X.quirks="0x2" 227 in loader.conf. If the drive requires the 4k sector quirk, set the 228 quirks entry to 0x3. 229 23020160330: 231 The FAST_DEPEND build option has been removed and its functionality is 232 now the one true way. The old mkdep(1) style of 'make depend' has 233 been removed. See 20160311 for further details. 234 23520160317: 236 Resource range types have grown from unsigned long to uintmax_t. All 237 drivers, and anything using libdevinfo, need to be recompiled. 238 23920160311: 240 WITH_FAST_DEPEND is now enabled by default for in-tree and out-of-tree 241 builds. It no longer runs mkdep(1) during 'make depend', and the 242 'make depend' stage can safely be skipped now as it is auto ran 243 when building 'make all' and will generate all SRCS and DPSRCS before 244 building anything else. Dependencies are gathered at compile time with 245 -MF flags kept in separate .depend files per object file. Users should 246 run 'make cleandepend' once if using -DNO_CLEAN to clean out older 247 stale .depend files. 248 24920160306: 250 On amd64, clang 3.8.0 can now insert sections of type AMD64_UNWIND into 251 kernel modules. Therefore, if you load any kernel modules at boot time, 252 please install the boot loaders after you install the kernel, but before 253 rebooting, e.g.: 254 255 make buildworld 256 make kernel KERNCONF=YOUR_KERNEL_HERE 257 make -C sys/boot install 258 <reboot in single user> 259 260 Then follow the usual steps, described in the General Notes section, 261 below. 262 26320160305: 264 Clang, llvm, lldb and compiler-rt have been upgraded to 3.8.0. Please 265 see the 20141231 entry below for information about prerequisites and 266 upgrading, if you are not already using clang 3.5.0 or higher. 267 26820160301: 269 The AIO subsystem is now a standard part of the kernel. The 270 VFS_AIO kernel option and aio.ko kernel module have been removed. 271 Due to stability concerns, asynchronous I/O requests are only 272 permitted on sockets and raw disks by default. To enable 273 asynchronous I/O requests on all file types, set the 274 vfs.aio.enable_unsafe sysctl to a non-zero value. 275 27620160226: 277 The ELF object manipulation tool objcopy is now provided by the 278 ELF Tool Chain project rather than by GNU binutils. It should be a 279 drop-in replacement, with the addition of arm64 support. The 280 (temporary) src.conf knob WITHOUT_ELFCOPY_AS_OBJCOPY knob may be set 281 to obtain the GNU version if necessary. 282 28320160129: 284 Building ZFS pools on top of zvols is prohibited by default. That 285 feature has never worked safely; it's always been prone to deadlocks. 286 Using a zvol as the backing store for a VM guest's virtual disk will 287 still work, even if the guest is using ZFS. Legacy behavior can be 288 restored by setting vfs.zfs.vol.recursive=1. 289 29020160119: 291 The NONE and HPN patches has been removed from OpenSSH. They are 292 still available in the security/openssh-portable port. 293 29420160113: 295 With the addition of ypldap(8), a new _ypldap user is now required 296 during installworld. "mergemaster -p" can be used to add the user 297 prior to installworld, as documented in the handbook. 298 29920151216: 300 The tftp loader (pxeboot) now uses the option root-path directive. As a 301 consequence it no longer looks for a pxeboot.4th file on the tftp 302 server. Instead it uses the regular /boot infrastructure as with the 303 other loaders. 304 30520151211: 306 The code to start recording plug and play data into the modules has 307 been committed. While the old tools will properly build a new kernel, 308 a number of warnings about "unknown metadata record 4" will be produced 309 for an older kldxref. To avoid such warnings, make sure to rebuild 310 the kernel toolchain (or world). Make sure that you have r292078 or 311 later when trying to build 292077 or later before rebuilding. 312 31320151207: 314 Debug data files are now built by default with 'make buildworld' and 315 installed with 'make installworld'. This facilitates debugging but 316 requires more disk space both during the build and for the installed 317 world. Debug files may be disabled by setting WITHOUT_DEBUG_FILES=yes 318 in src.conf(5). 319 32020151130: 321 r291527 changed the internal interface between the nfsd.ko and 322 nfscommon.ko modules. As such, they must both be upgraded to-gether. 323 __FreeBSD_version has been bumped because of this. 324 32520151108: 326 Add support for unicode collation strings leads to a change of 327 order of files listed by ls(1) for example. To get back to the old 328 behaviour, set LC_COLLATE environment variable to "C". 329 330 Databases administrators will need to reindex their databases given 331 collation results will be different. 332 333 Due to a bug in install(1) it is recommended to remove the ancient 334 locales before running make installworld. 335 336 rm -rf /usr/share/locale/* 337 33820151030: 339 The OpenSSL has been upgraded to 1.0.2d. Any binaries requiring 340 libcrypto.so.7 or libssl.so.7 must be recompiled. 341 34220151020: 343 Qlogic 24xx/25xx firmware images were updated from 5.5.0 to 7.3.0. 344 Kernel modules isp_2400_multi and isp_2500_multi were removed and 345 should be replaced with isp_2400 and isp_2500 modules respectively. 346 34720151017: 348 The build previously allowed using 'make -n' to not recurse into 349 sub-directories while showing what commands would be executed, and 350 'make -n -n' to recursively show commands. Now 'make -n' will recurse 351 and 'make -N' will not. 352 35320151012: 354 If you specify SENDMAIL_MC or SENDMAIL_CF in make.conf, mergemaster 355 and etcupdate will now use this file. A custom sendmail.cf is now 356 updated via this mechanism rather than via installworld. If you had 357 excluded sendmail.cf in mergemaster.rc or etcupdate.conf, you may 358 want to remove the exclusion or change it to "always install". 359 /etc/mail/sendmail.cf is now managed the same way regardless of 360 whether SENDMAIL_MC/SENDMAIL_CF is used. If you are not using 361 SENDMAIL_MC/SENDMAIL_CF there should be no change in behavior. 362 36320151011: 364 Compatibility shims for legacy ATA device names have been removed. 365 It includes ATA_STATIC_ID kernel option, kern.cam.ada.legacy_aliases 366 and kern.geom.raid.legacy_aliases loader tunables, kern.devalias.* 367 environment variables, /dev/ad* and /dev/ar* symbolic links. 368 36920151006: 370 Clang, llvm, lldb, compiler-rt and libc++ have been upgraded to 3.7.0. 371 Please see the 20141231 entry below for information about prerequisites 372 and upgrading, if you are not already using clang 3.5.0 or higher. 373 37420150924: 375 Kernel debug files have been moved to /usr/lib/debug/boot/kernel/, 376 and renamed from .symbols to .debug. This reduces the size requirements 377 on the boot partition or file system and provides consistency with 378 userland debug files. 379 380 When using the supported kernel installation method the 381 /usr/lib/debug/boot/kernel directory will be renamed (to kernel.old) 382 as is done with /boot/kernel. 383 384 Developers wishing to maintain the historical behavior of installing 385 debug files in /boot/kernel/ can set KERN_DEBUGDIR="" in src.conf(5). 386 38720150827: 388 The wireless drivers had undergone changes that remove the 'parent 389 interface' from the ifconfig -l output. The rc.d network scripts 390 used to check presence of a parent interface in the list, so old 391 scripts would fail to start wireless networking. Thus, etcupdate(3) 392 or mergemaster(8) run is required after kernel update, to update your 393 rc.d scripts in /etc. 394 39520150827: 396 pf no longer supports 'scrub fragment crop' or 'scrub fragment drop-ovl' 397 These configurations are now automatically interpreted as 398 'scrub fragment reassemble'. 399 40020150817: 401 Kernel-loadable modules for the random(4) device are back. To use 402 them, the kernel must have 403 404 device random 405 options RANDOM_LOADABLE 406 407 kldload(8) can then be used to load random_fortuna.ko 408 or random_yarrow.ko. Please note that due to the indirect 409 function calls that the loadable modules need to provide, 410 the build-in variants will be slightly more efficient. 411 412 The random(4) kernel option RANDOM_DUMMY has been retired due to 413 unpopularity. It was not all that useful anyway. 414 41520150813: 416 The WITHOUT_ELFTOOLCHAIN_TOOLS src.conf(5) knob has been retired. 417 Control over building the ELF Tool Chain tools is now provided by 418 the WITHOUT_TOOLCHAIN knob. 419 42020150810: 421 The polarity of Pulse Per Second (PPS) capture events with the 422 uart(4) driver has been corrected. Prior to this change the PPS 423 "assert" event corresponded to the trailing edge of a positive PPS 424 pulse and the "clear" event was the leading edge of the next pulse. 425 426 As the width of a PPS pulse in a typical GPS receiver is on the 427 order of 1 millisecond, most users will not notice any significant 428 difference with this change. 429 430 Anyone who has compensated for the historical polarity reversal by 431 configuring a negative offset equal to the pulse width will need to 432 remove that workaround. 433 43420150809: 435 The default group assigned to /dev/dri entries has been changed 436 from 'wheel' to 'video' with the id of '44'. If you want to have 437 access to the dri devices please add yourself to the video group 438 with: 439 440 # pw groupmod video -m $USER 441 44220150806: 443 The menu.rc and loader.rc files will now be replaced during 444 upgrades. Please migrate local changes to menu.rc.local and 445 loader.rc.local instead. 446 44720150805: 448 GNU Binutils versions of addr2line, c++filt, nm, readelf, size, 449 strings and strip have been removed. The src.conf(5) knob 450 WITHOUT_ELFTOOLCHAIN_TOOLS no longer provides the binutils tools. 451 45220150728: 453 As ZFS requires more kernel stack pages than is the default on some 454 architectures e.g. i386, it now warns if KSTACK_PAGES is less than 455 ZFS_MIN_KSTACK_PAGES (which is 4 at the time of writing). 456 457 Please consider using 'options KSTACK_PAGES=X' where X is greater 458 than or equal to ZFS_MIN_KSTACK_PAGES i.e. 4 in such configurations. 459 46020150706: 461 sendmail has been updated to 8.15.2. Starting with FreeBSD 11.0 462 and sendmail 8.15, sendmail uses uncompressed IPv6 addresses by 463 default, i.e., they will not contain "::". For example, instead 464 of ::1, it will be 0:0:0:0:0:0:0:1. This permits a zero subnet 465 to have a more specific match, such as different map entries for 466 IPv6:0:0 vs IPv6:0. This change requires that configuration 467 data (including maps, files, classes, custom ruleset, etc.) must 468 use the same format, so make certain such configuration data is 469 upgrading. As a very simple check search for patterns like 470 'IPv6:[0-9a-fA-F:]*::' and 'IPv6::'. To return to the old 471 behavior, set the m4 option confUSE_COMPRESSED_IPV6_ADDRESSES or 472 the cf option UseCompressedIPv6Addresses. 473 47420150630: 475 The default kernel entropy-processing algorithm is now 476 Fortuna, replacing Yarrow. 477 478 Assuming you have 'device random' in your kernel config 479 file, the configurations allow a kernel option to override 480 this default. You may choose *ONE* of: 481 482 options RANDOM_YARROW # Legacy /dev/random algorithm. 483 options RANDOM_DUMMY # Blocking-only driver. 484 485 If you have neither, you get Fortuna. For most people, 486 read no further, Fortuna will give a /dev/random that works 487 like it always used to, and the difference will be irrelevant. 488 489 If you remove 'device random', you get *NO* kernel-processed 490 entropy at all. This may be acceptable to folks building 491 embedded systems, but has complications. Carry on reading, 492 and it is assumed you know what you need. 493 494 *PLEASE* read random(4) and random(9) if you are in the 495 habit of tweaking kernel configs, and/or if you are a member 496 of the embedded community, wanting specific and not-usual 497 behaviour from your security subsystems. 498 499 NOTE!! If you use RANDOM_DUMMY and/or have no 'device 500 random', you will NOT have a functioning /dev/random, and 501 many cryptographic features will not work, including SSH. 502 You may also find strange behaviour from the random(3) set 503 of library functions, in particular sranddev(3), srandomdev(3) 504 and arc4random(3). The reason for this is that the KERN_ARND 505 sysctl only returns entropy if it thinks it has some to 506 share, and with RANDOM_DUMMY or no 'device random' this 507 will never happen. 508 50920150623: 510 An additional fix for the issue described in the 20150614 sendmail 511 entry below has been been committed in revision 284717. 512 51320150616: 514 FreeBSD's old make (fmake) has been removed from the system. It is 515 available as the devel/fmake port or via pkg install fmake. 516 51720150615: 518 The fix for the issue described in the 20150614 sendmail entry 519 below has been been committed in revision 284436. The work 520 around described in that entry is no longer needed unless the 521 default setting is overridden by a confDH_PARAMETERS configuration 522 setting of '5' or pointing to a 512 bit DH parameter file. 523 52420150614: 525 ALLOW_DEPRECATED_ATF_TOOLS/ATFFILE support has been removed from 526 atf.test.mk (included from bsd.test.mk). Please upgrade devel/atf 527 and devel/kyua to version 0.20+ and adjust any calling code to work 528 with Kyuafile and kyua. 529 53020150614: 531 The import of openssl to address the FreeBSD-SA-15:10.openssl 532 security advisory includes a change which rejects handshakes 533 with DH parameters below 768 bits. sendmail releases prior 534 to 8.15.2 (not yet released), defaulted to a 512 bit 535 DH parameter setting for client connections. To work around 536 this interoperability, sendmail can be configured to use a 537 2048 bit DH parameter by: 538 539 1. Edit /etc/mail/`hostname`.mc 540 2. If a setting for confDH_PARAMETERS does not exist or 541 exists and is set to a string beginning with '5', 542 replace it with '2'. 543 3. If a setting for confDH_PARAMETERS exists and is set to 544 a file path, create a new file with: 545 openssl dhparam -out /path/to/file 2048 546 4. Rebuild the .cf file: 547 cd /etc/mail/; make; make install 548 5. Restart sendmail: 549 cd /etc/mail/; make restart 550 551 A sendmail patch is coming, at which time this file will be 552 updated. 553 55420150604: 555 Generation of legacy formatted entries have been disabled by default 556 in pwd_mkdb(8), as all base system consumers of the legacy formatted 557 entries were converted to use the new format by default when the new, 558 machine independent format have been added and supported since FreeBSD 559 5.x. 560 561 Please see the pwd_mkdb(8) manual page for further details. 562 56320150525: 564 Clang and llvm have been upgraded to 3.6.1 release. Please see the 565 20141231 entry below for information about prerequisites and upgrading, 566 if you are not already using 3.5.0 or higher. 567 56820150521: 569 TI platform code switched to using vendor DTS files and this update 570 may break existing systems running on Beaglebone, Beaglebone Black, 571 and Pandaboard: 572 573 - dtb files should be regenerated/reinstalled. Filenames are the 574 same but content is different now 575 - GPIO addressing was changed, now each GPIO bank (32 pins per bank) 576 has its own /dev/gpiocX device, e.g. pin 121 on /dev/gpioc0 in old 577 addressing scheme is now pin 25 on /dev/gpioc3. 578 - Pandaboard: /etc/ttys should be updated, serial console device is 579 now /dev/ttyu2, not /dev/ttyu0 580 58120150501: 582 soelim(1) from gnu/usr.bin/groff has been replaced by usr.bin/soelim. 583 If you need the GNU extension from groff soelim(1), install groff 584 from package: pkg install groff, or via ports: textproc/groff. 585 58620150423: 587 chmod, chflags, chown and chgrp now affect symlinks in -R mode as 588 defined in symlink(7); previously symlinks were silently ignored. 589 59020150415: 591 The const qualifier has been removed from iconv(3) to comply with 592 POSIX. The ports tree is aware of this from r384038 onwards. 593 59420150416: 595 Libraries specified by LIBADD in Makefiles must have a corresponding 596 DPADD_<lib> variable to ensure correct dependencies. This is now 597 enforced in src.libnames.mk. 598 59920150324: 600 From legacy ata(4) driver was removed support for SATA controllers 601 supported by more functional drivers ahci(4), siis(4) and mvs(4). 602 Kernel modules ataahci and ataadaptec were removed completely, 603 replaced by ahci and mvs modules respectively. 604 60520150315: 606 Clang, llvm and lldb have been upgraded to 3.6.0 release. Please see 607 the 20141231 entry below for information about prerequisites and 608 upgrading, if you are not already using 3.5.0 or higher. 609 61020150307: 611 The 32-bit PowerPC kernel has been changed to a position-independent 612 executable. This can only be booted with a version of loader(8) 613 newer than January 31, 2015, so make sure to update both world and 614 kernel before rebooting. 615 61620150217: 617 If you are running a -CURRENT kernel since r273872 (Oct 30th, 2014), 618 but before r278950, the RNG was not seeded properly. Immediately 619 upgrade the kernel to r278950 or later and regenerate any keys (e.g. 620 ssh keys or openssl keys) that were generated w/ a kernel from that 621 range. This does not affect programs that directly used /dev/random 622 or /dev/urandom. All userland uses of arc4random(3) are affected. 623 62420150210: 625 The autofs(4) ABI was changed in order to restore binary compatibility 626 with 10.1-RELEASE. The automountd(8) daemon needs to be rebuilt to work 627 with the new kernel. 628 62920150131: 630 The powerpc64 kernel has been changed to a position-independent 631 executable. This can only be booted with a new version of loader(8), 632 so make sure to update both world and kernel before rebooting. 633 63420150118: 635 Clang and llvm have been upgraded to 3.5.1 release. This is a bugfix 636 only release, no new features have been added. Please see the 20141231 637 entry below for information about prerequisites and upgrading, if you 638 are not already using 3.5.0. 639 64020150107: 641 ELF tools addr2line, elfcopy (strip), nm, size, and strings are now 642 taken from the ELF Tool Chain project rather than GNU binutils. They 643 should be drop-in replacements, with the addition of arm64 support. 644 The WITHOUT_ELFTOOLCHAIN_TOOLS= knob may be used to obtain the 645 binutils tools, if necessary. See 20150805 for updated information. 646 64720150105: 648 The default Unbound configuration now enables remote control 649 using a local socket. Users who have already enabled the 650 local_unbound service should regenerate their configuration 651 by running "service local_unbound setup" as root. 652 65320150102: 654 The GNU texinfo and GNU info pages have been removed. 655 To be able to view GNU info pages please install texinfo from ports. 656 65720141231: 658 Clang, llvm and lldb have been upgraded to 3.5.0 release. 659 660 As of this release, a prerequisite for building clang, llvm and lldb is 661 a C++11 capable compiler and C++11 standard library. This means that to 662 be able to successfully build the cross-tools stage of buildworld, with 663 clang as the bootstrap compiler, your system compiler or cross compiler 664 should either be clang 3.3 or later, or gcc 4.8 or later, and your 665 system C++ library should be libc++, or libdstdc++ from gcc 4.8 or 666 later. 667 668 On any standard FreeBSD 10.x or 11.x installation, where clang and 669 libc++ are on by default (that is, on x86 or arm), this should work out 670 of the box. 671 672 On 9.x installations where clang is enabled by default, e.g. on x86 and 673 powerpc, libc++ will not be enabled by default, so libc++ should be 674 built (with clang) and installed first. If both clang and libc++ are 675 missing, build clang first, then use it to build libc++. 676 677 On 8.x and earlier installations, upgrade to 9.x first, and then follow 678 the instructions for 9.x above. 679 680 Sparc64 and mips users are unaffected, as they still use gcc 4.2.1 by 681 default, and do not build clang. 682 683 Many embedded systems are resource constrained, and will not be able to 684 build clang in a reasonable time, or in some cases at all. In those 685 cases, cross building bootable systems on amd64 is a workaround. 686 687 This new version of clang introduces a number of new warnings, of which 688 the following are most likely to appear: 689 690 -Wabsolute-value 691 692 This warns in two cases, for both C and C++: 693 * When the code is trying to take the absolute value of an unsigned 694 quantity, which is effectively a no-op, and almost never what was 695 intended. The code should be fixed, if at all possible. If you are 696 sure that the unsigned quantity can be safely cast to signed, without 697 loss of information or undefined behavior, you can add an explicit 698 cast, or disable the warning. 699 700 * When the code is trying to take an absolute value, but the called 701 abs() variant is for the wrong type, which can lead to truncation. 702 If you want to disable the warning instead of fixing the code, please 703 make sure that truncation will not occur, or it might lead to unwanted 704 side-effects. 705 706 -Wtautological-undefined-compare and 707 -Wundefined-bool-conversion 708 709 These warn when C++ code is trying to compare 'this' against NULL, while 710 'this' should never be NULL in well-defined C++ code. However, there is 711 some legacy (pre C++11) code out there, which actively abuses this 712 feature, which was less strictly defined in previous C++ versions. 713 714 Squid and openjdk do this, for example. The warning can be turned off 715 for C++98 and earlier, but compiling the code in C++11 mode might result 716 in unexpected behavior; for example, the parts of the program that are 717 unreachable could be optimized away. 718 71920141222: 720 The old NFS client and server (kernel options NFSCLIENT, NFSSERVER) 721 kernel sources have been removed. The .h files remain, since some 722 utilities include them. This will need to be fixed later. 723 If "mount -t oldnfs ..." is attempted, it will fail. 724 If the "-o" option on mountd(8), nfsd(8) or nfsstat(1) is used, 725 the utilities will report errors. 726 72720141121: 728 The handling of LOCAL_LIB_DIRS has been altered to skip addition of 729 directories to top level SUBDIR variable when their parent 730 directory is included in LOCAL_DIRS. Users with build systems with 731 such hierarchies and without SUBDIR entries in the parent 732 directory Makefiles should add them or add the directories to 733 LOCAL_DIRS. 734 73520141109: 736 faith(4) and faithd(8) have been removed from the base system. Faith 737 has been obsolete for a very long time. 738 73920141104: 740 vt(4), the new console driver, is enabled by default. It brings 741 support for Unicode and double-width characters, as well as 742 support for UEFI and integration with the KMS kernel video 743 drivers. 744 745 You may need to update your console settings in /etc/rc.conf, 746 most probably the keymap. During boot, /etc/rc.d/syscons will 747 indicate what you need to do. 748 749 vt(4) still has issues and lacks some features compared to 750 syscons(4). See the wiki for up-to-date information: 751 https://wiki.freebsd.org/Newcons 752 753 If you want to keep using syscons(4), you can do so by adding 754 the following line to /boot/loader.conf: 755 kern.vty=sc 756 75720141102: 758 pjdfstest has been integrated into kyua as an opt-in test suite. 759 Please see share/doc/pjdfstest/README for more details on how to 760 execute it. 761 76220141009: 763 gperf has been removed from the base system for architectures 764 that use clang. Ports that require gperf will obtain it from the 765 devel/gperf port. 766 76720140923: 768 pjdfstest has been moved from tools/regression/pjdfstest to 769 contrib/pjdfstest . 770 77120140922: 772 At svn r271982, The default linux compat kernel ABI has been adjusted 773 to 2.6.18 in support of the linux-c6 compat ports infrastructure 774 update. If you wish to continue using the linux-f10 compat ports, 775 add compat.linux.osrelease=2.6.16 to your local sysctl.conf. Users are 776 encouraged to update their linux-compat packages to linux-c6 during 777 their next update cycle. 778 77920140729: 780 The ofwfb driver, used to provide a graphics console on PowerPC when 781 using vt(4), no longer allows mmap() of all physical memory. This 782 will prevent Xorg on PowerPC with some ATI graphics cards from 783 initializing properly unless x11-servers/xorg-server is updated to 784 1.12.4_8 or newer. 785 78620140723: 787 The xdev targets have been converted to using TARGET and 788 TARGET_ARCH instead of XDEV and XDEV_ARCH. 789 79020140719: 791 The default unbound configuration has been modified to address 792 issues with reverse lookups on networks that use private 793 address ranges. If you use the local_unbound service, run 794 "service local_unbound setup" as root to regenerate your 795 configuration, then "service local_unbound reload" to load the 796 new configuration. 797 79820140709: 799 The GNU texinfo and GNU info pages are not built and installed 800 anymore, WITH_INFO knob has been added to allow to built and install 801 them again. 802 UPDATE: see 20150102 entry on texinfo's removal 803 80420140708: 805 The GNU readline library is now an INTERNALLIB - that is, it is 806 statically linked into consumers (GDB and variants) in the base 807 system, and the shared library is no longer installed. The 808 devel/readline port is available for third party software that 809 requires readline. 810 81120140702: 812 The Itanium architecture (ia64) has been removed from the list of 813 known architectures. This is the first step in the removal of the 814 architecture. 815 81620140701: 817 Commit r268115 has added NFSv4.1 server support, merged from 818 projects/nfsv4.1-server. Since this includes changes to the 819 internal interfaces between the NFS related modules, a full 820 build of the kernel and modules will be necessary. 821 __FreeBSD_version has been bumped. 822 82320140629: 824 The WITHOUT_VT_SUPPORT kernel config knob has been renamed 825 WITHOUT_VT. (The other _SUPPORT knobs have a consistent meaning 826 which differs from the behaviour controlled by this knob.) 827 82820140619: 829 Maximal length of the serial number in CTL was increased from 16 to 830 64 chars, that breaks ABI. All CTL-related tools, such as ctladm 831 and ctld, need to be rebuilt to work with a new kernel. 832 83320140606: 834 The libatf-c and libatf-c++ major versions were downgraded to 0 and 835 1 respectively to match the upstream numbers. They were out of 836 sync because, when they were originally added to FreeBSD, the 837 upstream versions were not respected. These libraries are private 838 and not yet built by default, so renumbering them should be a 839 non-issue. However, unclean source trees will yield broken test 840 programs once the operator executes "make delete-old-libs" after a 841 "make installworld". 842 843 Additionally, the atf-sh binary was made private by moving it into 844 /usr/libexec/. Already-built shell test programs will keep the 845 path to the old binary so they will break after "make delete-old" 846 is run. 847 848 If you are using WITH_TESTS=yes (not the default), wipe the object 849 tree and rebuild from scratch to prevent spurious test failures. 850 This is only needed once: the misnumbered libraries and misplaced 851 binaries have been added to OptionalObsoleteFiles.inc so they will 852 be removed during a clean upgrade. 853 85420140512: 855 Clang and llvm have been upgraded to 3.4.1 release. 856 85720140508: 858 We bogusly installed src.opts.mk in /usr/share/mk. This file should 859 be removed to avoid issues in the future (and has been added to 860 ObsoleteFiles.inc). 861 86220140505: 863 /etc/src.conf now affects only builds of the FreeBSD src tree. In the 864 past, it affected all builds that used the bsd.*.mk files. The old 865 behavior was a bug, but people may have relied upon it. To get this 866 behavior back, you can .include /etc/src.conf from /etc/make.conf 867 (which is still global and isn't changed). This also changes the 868 behavior of incremental builds inside the tree of individual 869 directories. Set MAKESYSPATH to ".../share/mk" to do that. 870 Although this has survived make universe and some upgrade scenarios, 871 other upgrade scenarios may have broken. At least one form of 872 temporary breakage was fixed with MAKESYSPATH settings for buildworld 873 as well... In cases where MAKESYSPATH isn't working with this 874 setting, you'll need to set it to the full path to your tree. 875 876 One side effect of all this cleaning up is that bsd.compiler.mk 877 is no longer implicitly included by bsd.own.mk. If you wish to 878 use COMPILER_TYPE, you must now explicitly include bsd.compiler.mk 879 as well. 880 88120140430: 882 The lindev device has been removed since /dev/full has been made a 883 standard device. __FreeBSD_version has been bumped. 884 88520140424: 886 The knob WITHOUT_VI was added to the base system, which controls 887 building ex(1), vi(1), etc. Older releases of FreeBSD required ex(1) 888 in order to reorder files share/termcap and didn't build ex(1) as a 889 build tool, so building/installing with WITH_VI is highly advised for 890 build hosts for older releases. 891 892 This issue has been fixed in stable/9 and stable/10 in r277022 and 893 r276991, respectively. 894 89520140418: 896 The YES_HESIOD knob has been removed. It has been obsolete for 897 a decade. Please move to using WITH_HESIOD instead or your builds 898 will silently lack HESIOD. 899 90020140405: 901 The uart(4) driver has been changed with respect to its handling 902 of the low-level console. Previously the uart(4) driver prevented 903 any process from changing the baudrate or the CLOCAL and HUPCL 904 control flags. By removing the restrictions, operators can make 905 changes to the serial console port without having to reboot. 906 However, when getty(8) is started on the serial device that is 907 associated with the low-level console, a misconfigured terminal 908 line in /etc/ttys will now have a real impact. 909 Before upgrading the kernel, make sure that /etc/ttys has the 910 serial console device configured as 3wire without baudrate to 911 preserve the previous behaviour. E.g: 912 ttyu0 "/usr/libexec/getty 3wire" vt100 on secure 913 91420140306: 915 Support for libwrap (TCP wrappers) in rpcbind was disabled by default 916 to improve performance. To re-enable it, if needed, run rpcbind 917 with command line option -W. 918 91920140226: 920 Switched back to the GPL dtc compiler due to updates in the upstream 921 dts files not being supported by the BSDL dtc compiler. You will need 922 to rebuild your kernel toolchain to pick up the new compiler. Core dumps 923 may result while building dtb files during a kernel build if you fail 924 to do so. Set WITHOUT_GPL_DTC if you require the BSDL compiler. 925 92620140216: 927 Clang and llvm have been upgraded to 3.4 release. 928 92920140216: 930 The nve(4) driver has been removed. Please use the nfe(4) driver 931 for NVIDIA nForce MCP Ethernet adapters instead. 932 93320140212: 934 An ABI incompatibility crept into the libc++ 3.4 import in r261283. 935 This could cause certain C++ applications using shared libraries built 936 against the previous version of libc++ to crash. The incompatibility 937 has now been fixed, but any C++ applications or shared libraries built 938 between r261283 and r261801 should be recompiled. 939 94020140204: 941 OpenSSH will now ignore errors caused by kernel lacking of Capsicum 942 capability mode support. Please note that enabling the feature in 943 kernel is still highly recommended. 944 94520140131: 946 OpenSSH is now built with sandbox support, and will use sandbox as 947 the default privilege separation method. This requires Capsicum 948 capability mode support in kernel. 949 95020140128: 951 The libelf and libdwarf libraries have been updated to newer 952 versions from upstream. Shared library version numbers for 953 these two libraries were bumped. Any ports or binaries 954 requiring these two libraries should be recompiled. 955 __FreeBSD_version is bumped to 1100006. 956 95720140110: 958 If a Makefile in a tests/ directory was auto-generating a Kyuafile 959 instead of providing an explicit one, this would prevent such 960 Makefile from providing its own Kyuafile in the future during 961 NO_CLEAN builds. This has been fixed in the Makefiles but manual 962 intervention is needed to clean an objdir if you use NO_CLEAN: 963 # find /usr/obj -name Kyuafile | xargs rm -f 964 96520131213: 966 The behavior of gss_pseudo_random() for the krb5 mechanism 967 has changed, for applications requesting a longer random string 968 than produced by the underlying enctype's pseudo-random() function. 969 In particular, the random string produced from a session key of 970 enctype aes256-cts-hmac-sha1-96 or aes256-cts-hmac-sha1-96 will 971 be different at the 17th octet and later, after this change. 972 The counter used in the PRF+ construction is now encoded as a 973 big-endian integer in accordance with RFC 4402. 974 __FreeBSD_version is bumped to 1100004. 975 97620131108: 977 The WITHOUT_ATF build knob has been removed and its functionality 978 has been subsumed into the more generic WITHOUT_TESTS. If you were 979 using the former to disable the build of the ATF libraries, you 980 should change your settings to use the latter. 981 98220131025: 983 The default version of mtree is nmtree which is obtained from 984 NetBSD. The output is generally the same, but may vary 985 slightly. If you found you need identical output adding 986 "-F freebsd9" to the command line should do the trick. For the 987 time being, the old mtree is available as fmtree. 988 98920131014: 990 libbsdyml has been renamed to libyaml and moved to /usr/lib/private. 991 This will break ports-mgmt/pkg. Rebuild the port, or upgrade to pkg 992 1.1.4_8 and verify bsdyml not linked in, before running "make 993 delete-old-libs": 994 # make -C /usr/ports/ports-mgmt/pkg build deinstall install clean 995 or 996 # pkg install pkg; ldd /usr/local/sbin/pkg | grep bsdyml 997 99820131010: 999 The stable/10 branch has been created in subversion from head 1000 revision r256279. 1001 100220131010: 1003 The rc.d/jail script has been updated to support jail(8) 1004 configuration file. The "jail_<jname>_*" rc.conf(5) variables 1005 for per-jail configuration are automatically converted to 1006 /var/run/jail.<jname>.conf before the jail(8) utility is invoked. 1007 This is transparently backward compatible. See below about some 1008 incompatibilities and rc.conf(5) manual page for more details. 1009 1010 These variables are now deprecated in favor of jail(8) configuration 1011 file. One can use "rc.d/jail config <jname>" command to generate 1012 a jail(8) configuration file in /var/run/jail.<jname>.conf without 1013 running the jail(8) utility. The default pathname of the 1014 configuration file is /etc/jail.conf and can be specified by 1015 using $jail_conf or $jail_<jname>_conf variables. 1016 1017 Please note that jail_devfs_ruleset accepts an integer at 1018 this moment. Please consider to rewrite the ruleset name 1019 with an integer. 1020 102120130930: 1022 BIND has been removed from the base system. If all you need 1023 is a local resolver, simply enable and start the local_unbound 1024 service instead. Otherwise, several versions of BIND are 1025 available in the ports tree. The dns/bind99 port is one example. 1026 1027 With this change, nslookup(1) and dig(1) are no longer in the base 1028 system. Users should instead use host(1) and drill(1) which are 1029 in the base system. Alternatively, nslookup and dig can 1030 be obtained by installing the dns/bind-tools port. 1031 103220130916: 1033 With the addition of unbound(8), a new unbound user is now 1034 required during installworld. "mergemaster -p" can be used to 1035 add the user prior to installworld, as documented in the handbook. 1036 103720130911: 1038 OpenSSH is now built with DNSSEC support, and will by default 1039 silently trust signed SSHFP records. This can be controlled with 1040 the VerifyHostKeyDNS client configuration setting. DNSSEC support 1041 can be disabled entirely with the WITHOUT_LDNS option in src.conf. 1042 104320130906: 1044 The GNU Compiler Collection and C++ standard library (libstdc++) 1045 are no longer built by default on platforms where clang is the system 1046 compiler. You can enable them with the WITH_GCC and WITH_GNUCXX 1047 options in src.conf. 1048 104920130905: 1050 The PROCDESC kernel option is now part of the GENERIC kernel 1051 configuration and is required for the rwhod(8) to work. 1052 If you are using custom kernel configuration, you should include 1053 'options PROCDESC'. 1054 105520130905: 1056 The API and ABI related to the Capsicum framework was modified 1057 in backward incompatible way. The userland libraries and programs 1058 have to be recompiled to work with the new kernel. This includes the 1059 following libraries and programs, but the whole buildworld is 1060 advised: libc, libprocstat, dhclient, tcpdump, hastd, hastctl, 1061 kdump, procstat, rwho, rwhod, uniq. 1062 106320130903: 1064 AES-NI intrinsic support has been added to gcc. The AES-NI module 1065 has been updated to use this support. A new gcc is required to build 1066 the aesni module on both i386 and amd64. 1067 106820130821: 1069 The PADLOCK_RNG and RDRAND_RNG kernel options are now devices. 1070 Thus "device padlock_rng" and "device rdrand_rng" should be 1071 used instead of "options PADLOCK_RNG" & "options RDRAND_RNG". 1072 107320130813: 1074 WITH_ICONV has been split into two feature sets. WITH_ICONV now 1075 enables just the iconv* functionality and is now on by default. 1076 WITH_LIBICONV_COMPAT enables the libiconv api and link time 1077 compatibility. Set WITHOUT_ICONV to build the old way. 1078 If you have been using WITH_ICONV before, you will very likely 1079 need to turn on WITH_LIBICONV_COMPAT. 1080 108120130806: 1082 INVARIANTS option now enables DEBUG for code with OpenSolaris and 1083 Illumos origin, including ZFS. If you have INVARIANTS in your 1084 kernel configuration, then there is no need to set DEBUG or ZFS_DEBUG 1085 explicitly. 1086 DEBUG used to enable witness(9) tracking of OpenSolaris (mostly ZFS) 1087 locks if WITNESS option was set. Because that generated a lot of 1088 witness(9) reports and all of them were believed to be false 1089 positives, this is no longer done. New option OPENSOLARIS_WITNESS 1090 can be used to achieve the previous behavior. 1091 109220130806: 1093 Timer values in IPv6 data structures now use time_uptime instead 1094 of time_second. Although this is not a user-visible functional 1095 change, userland utilities which directly use them---ndp(8), 1096 rtadvd(8), and rtsold(8) in the base system---need to be updated 1097 to r253970 or later. 1098 109920130802: 1100 find -delete can now delete the pathnames given as arguments, 1101 instead of only files found below them or if the pathname did 1102 not contain any slashes. Formerly, the following error message 1103 would result: 1104 1105 find: -delete: <path>: relative path potentially not safe 1106 1107 Deleting the pathnames given as arguments can be prevented 1108 without error messages using -mindepth 1 or by changing 1109 directory and passing "." as argument to find. This works in the 1110 old as well as the new version of find. 1111 111220130726: 1113 Behavior of devfs rules path matching has been changed. 1114 Pattern is now always matched against fully qualified devfs 1115 path and slash characters must be explicitly matched by 1116 slashes in pattern (FNM_PATHNAME). Rulesets involving devfs 1117 subdirectories must be reviewed. 1118 111920130716: 1120 The default ARM ABI has changed to the ARM EABI. The old ABI is 1121 incompatible with the ARM EABI and all programs and modules will 1122 need to be rebuilt to work with a new kernel. 1123 1124 To keep using the old ABI ensure the WITHOUT_ARM_EABI knob is set. 1125 1126 NOTE: Support for the old ABI will be removed in the future and 1127 users are advised to upgrade. 1128 112920130709: 1130 pkg_install has been disconnected from the build if you really need it 1131 you should add WITH_PKGTOOLS in your src.conf(5). 1132 113320130709: 1134 Most of network statistics structures were changed to be able 1135 keep 64-bits counters. Thus all tools, that work with networking 1136 statistics, must be rebuilt (netstat(1), bsnmpd(1), etc.) 1137 113820130618: 1139 Fix a bug that allowed a tracing process (e.g. gdb) to write 1140 to a memory-mapped file in the traced process's address space 1141 even if neither the traced process nor the tracing process had 1142 write access to that file. 1143 114420130615: 1145 CVS has been removed from the base system. An exact copy 1146 of the code is available from the devel/cvs port. 1147 114820130613: 1149 Some people report the following error after the switch to bmake: 1150 1151 make: illegal option -- J 1152 usage: make [-BPSXeiknpqrstv] [-C directory] [-D variable] 1153 ... 1154 *** [buildworld] Error code 2 1155 1156 this likely due to an old instance of make in 1157 ${MAKEPATH} (${MAKEOBJDIRPREFIX}${.CURDIR}/make.${MACHINE}) 1158 which src/Makefile will use that blindly, if it exists, so if 1159 you see the above error: 1160 1161 rm -rf `make -V MAKEPATH` 1162 1163 should resolve it. 1164 116520130516: 1166 Use bmake by default. 1167 Whereas before one could choose to build with bmake via 1168 -DWITH_BMAKE one must now use -DWITHOUT_BMAKE to use the old 1169 make. The goal is to remove these knobs for 10-RELEASE. 1170 1171 It is worth noting that bmake (like gmake) treats the command 1172 line as the unit of failure, rather than statements within the 1173 command line. Thus '(cd some/where && dosomething)' is safer 1174 than 'cd some/where; dosomething'. The '()' allows consistent 1175 behavior in parallel build. 1176 117720130429: 1178 Fix a bug that allows NFS clients to issue READDIR on files. 1179 118020130426: 1181 The WITHOUT_IDEA option has been removed because 1182 the IDEA patent expired. 1183 118420130426: 1185 The sysctl which controls TRIM support under ZFS has been renamed 1186 from vfs.zfs.trim_disable -> vfs.zfs.trim.enabled and has been 1187 enabled by default. 1188 118920130425: 1190 The mergemaster command now uses the default MAKEOBJDIRPREFIX 1191 rather than creating it's own in the temporary directory in 1192 order allow access to bootstrapped versions of tools such as 1193 install and mtree. When upgrading from version of FreeBSD where 1194 the install command does not support -l, you will need to 1195 install a new mergemaster command if mergemaster -p is required. 1196 This can be accomplished with the command (cd src/usr.sbin/mergemaster 1197 && make install). 1198 119920130404: 1200 Legacy ATA stack, disabled and replaced by new CAM-based one since 1201 FreeBSD 9.0, completely removed from the sources. Kernel modules 1202 atadisk and atapi*, user-level tools atacontrol and burncd are 1203 removed. Kernel option `options ATA_CAM` is now permanently enabled 1204 and removed. 1205 120620130319: 1207 SOCK_CLOEXEC and SOCK_NONBLOCK flags have been added to socket(2) 1208 and socketpair(2). Software, in particular Kerberos, may 1209 automatically detect and use these during building. The resulting 1210 binaries will not work on older kernels. 1211 121220130308: 1213 CTL_DISABLE has also been added to the sparc64 GENERIC (for further 1214 information, see the respective 20130304 entry). 1215 121620130304: 1217 Recent commits to callout(9) changed the size of struct callout, 1218 so the KBI is probably heavily disturbed. Also, some functions 1219 in callout(9)/sleep(9)/sleepqueue(9)/condvar(9) KPIs were replaced 1220 by macros. Every kernel module using it won't load, so rebuild 1221 is requested. 1222 1223 The ctl device has been re-enabled in GENERIC for i386 and amd64, 1224 but does not initialize by default (because of the new CTL_DISABLE 1225 option) to save memory. To re-enable it, remove the CTL_DISABLE 1226 option from the kernel config file or set kern.cam.ctl.disable=0 1227 in /boot/loader.conf. 1228 122920130301: 1230 The ctl device has been disabled in GENERIC for i386 and amd64. 1231 This was done due to the extra memory being allocated at system 1232 initialisation time by the ctl driver which was only used if 1233 a CAM target device was created. This makes a FreeBSD system 1234 unusable on 128MB or less of RAM. 1235 123620130208: 1237 A new compression method (lz4) has been merged to -HEAD. Please 1238 refer to zpool-features(7) for more information. 1239 1240 Please refer to the "ZFS notes" section of this file for information 1241 on upgrading boot ZFS pools. 1242 124320130129: 1244 A BSD-licensed patch(1) variant has been added and is installed 1245 as bsdpatch, being the GNU version the default patch. 1246 To inverse the logic and use the BSD-licensed one as default, 1247 while having the GNU version installed as gnupatch, rebuild 1248 and install world with the WITH_BSD_PATCH knob set. 1249 125020130121: 1251 Due to the use of the new -l option to install(1) during build 1252 and install, you must take care not to directly set the INSTALL 1253 make variable in your /etc/make.conf, /etc/src.conf, or on the 1254 command line. If you wish to use the -C flag for all installs 1255 you may be able to add INSTALL+=-C to /etc/make.conf or 1256 /etc/src.conf. 1257 125820130118: 1259 The install(1) option -M has changed meaning and now takes an 1260 argument that is a file or path to append logs to. In the 1261 unlikely event that -M was the last option on the command line 1262 and the command line contained at least two files and a target 1263 directory the first file will have logs appended to it. The -M 1264 option served little practical purpose in the last decade so its 1265 use is expected to be extremely rare. 1266 126720121223: 1268 After switching to Clang as the default compiler some users of ZFS 1269 on i386 systems started to experience stack overflow kernel panics. 1270 Please consider using 'options KSTACK_PAGES=4' in such configurations. 1271 127220121222: 1273 GEOM_LABEL now mangles label names read from file system metadata. 1274 Mangling affect labels containing spaces, non-printable characters, 1275 '%' or '"'. Device names in /etc/fstab and other places may need to 1276 be updated. 1277 127820121217: 1279 By default, only the 10 most recent kernel dumps will be saved. To 1280 restore the previous behaviour (no limit on the number of kernel dumps 1281 stored in the dump directory) add the following line to /etc/rc.conf: 1282 1283 savecore_flags="" 1284 128520121201: 1286 With the addition of auditdistd(8), a new auditdistd user is now 1287 required during installworld. "mergemaster -p" can be used to 1288 add the user prior to installworld, as documented in the handbook. 1289 129020121117: 1291 The sin6_scope_id member variable in struct sockaddr_in6 is now 1292 filled by the kernel before passing the structure to the userland via 1293 sysctl or routing socket. This means the KAME-specific embedded scope 1294 id in sin6_addr.s6_addr[2] is always cleared in userland application. 1295 This behavior can be controlled by net.inet6.ip6.deembed_scopeid. 1296 __FreeBSD_version is bumped to 1000025. 1297 129820121105: 1299 On i386 and amd64 systems WITH_CLANG_IS_CC is now the default. 1300 This means that the world and kernel will be compiled with clang 1301 and that clang will be installed as /usr/bin/cc, /usr/bin/c++, 1302 and /usr/bin/cpp. To disable this behavior and revert to building 1303 with gcc, compile with WITHOUT_CLANG_IS_CC. Really old versions 1304 of current may need to bootstrap WITHOUT_CLANG first if the clang 1305 build fails (its compatibility window doesn't extend to the 9 stable 1306 branch point). 1307 130820121102: 1309 The IPFIREWALL_FORWARD kernel option has been removed. Its 1310 functionality now turned on by default. 1311 131220121023: 1313 The ZERO_COPY_SOCKET kernel option has been removed and 1314 split into SOCKET_SEND_COW and SOCKET_RECV_PFLIP. 1315 NB: SOCKET_SEND_COW uses the VM page based copy-on-write 1316 mechanism which is not safe and may result in kernel crashes. 1317 NB: The SOCKET_RECV_PFLIP mechanism is useless as no current 1318 driver supports disposeable external page sized mbuf storage. 1319 Proper replacements for both zero-copy mechanisms are under 1320 consideration and will eventually lead to complete removal 1321 of the two kernel options. 1322 132320121023: 1324 The IPv4 network stack has been converted to network byte 1325 order. The following modules need to be recompiled together 1326 with kernel: carp(4), divert(4), gif(4), siftr(4), gre(4), 1327 pf(4), ipfw(4), ng_ipfw(4), stf(4). 1328 132920121022: 1330 Support for non-MPSAFE filesystems was removed from VFS. The 1331 VFS_VERSION was bumped, all filesystem modules shall be 1332 recompiled. 1333 133420121018: 1335 All the non-MPSAFE filesystems have been disconnected from 1336 the build. The full list includes: codafs, hpfs, ntfs, nwfs, 1337 portalfs, smbfs, xfs. 1338 133920121016: 1340 The interface cloning API and ABI has changed. The following 1341 modules need to be recompiled together with kernel: 1342 ipfw(4), pfsync(4), pflog(4), usb(4), wlan(4), stf(4), 1343 vlan(4), disc(4), edsc(4), if_bridge(4), gif(4), tap(4), 1344 faith(4), epair(4), enc(4), tun(4), if_lagg(4), gre(4). 1345 134620121015: 1347 The sdhci driver was split in two parts: sdhci (generic SD Host 1348 Controller logic) and sdhci_pci (actual hardware driver). 1349 No kernel config modifications are required, but if you 1350 load sdhc as a module you must switch to sdhci_pci instead. 1351 135220121014: 1353 Import the FUSE kernel and userland support into base system. 1354 135520121013: 1356 The GNU sort(1) program has been removed since the BSD-licensed 1357 sort(1) has been the default for quite some time and no serious 1358 problems have been reported. The corresponding WITH_GNU_SORT 1359 knob has also gone. 1360 136120121006: 1362 The pfil(9) API/ABI for AF_INET family has been changed. Packet 1363 filtering modules: pf(4), ipfw(4), ipfilter(4) need to be recompiled 1364 with new kernel. 1365 136620121001: 1367 The net80211(4) ABI has been changed to allow for improved driver 1368 PS-POLL and power-save support. All wireless drivers need to be 1369 recompiled to work with the new kernel. 1370 137120120913: 1372 The random(4) support for the VIA hardware random number 1373 generator (`PADLOCK') is no longer enabled unconditionally. 1374 Add the padlock_rng device in the custom kernel config if 1375 needed. The GENERIC kernels on i386 and amd64 do include the 1376 device, so the change only affects the custom kernel 1377 configurations. 1378 137920120908: 1380 The pf(4) packet filter ABI has been changed. pfctl(8) and 1381 snmp_pf module need to be recompiled to work with new kernel. 1382 138320120828: 1384 A new ZFS feature flag "com.delphix:empty_bpobj" has been merged 1385 to -HEAD. Pools that have empty_bpobj in active state can not be 1386 imported read-write with ZFS implementations that do not support 1387 this feature. For more information read the zpool-features(5) 1388 manual page. 1389 139020120727: 1391 The sparc64 ZFS loader has been changed to no longer try to auto- 1392 detect ZFS providers based on diskN aliases but now requires these 1393 to be explicitly listed in the OFW boot-device environment variable. 1394 139520120712: 1396 The OpenSSL has been upgraded to 1.0.1c. Any binaries requiring 1397 libcrypto.so.6 or libssl.so.6 must be recompiled. Also, there are 1398 configuration changes. Make sure to merge /etc/ssl/openssl.cnf. 1399 140020120712: 1401 The following sysctls and tunables have been renamed for consistency 1402 with other variables: 1403 kern.cam.da.da_send_ordered -> kern.cam.da.send_ordered 1404 kern.cam.ada.ada_send_ordered -> kern.cam.ada.send_ordered 1405 140620120628: 1407 The sort utility has been replaced with BSD sort. For now, GNU sort 1408 is also available as "gnusort" or the default can be set back to 1409 GNU sort by setting WITH_GNU_SORT. In this case, BSD sort will be 1410 installed as "bsdsort". 1411 141220120611: 1413 A new version of ZFS (pool version 5000) has been merged to -HEAD. 1414 Starting with this version the old system of ZFS pool versioning 1415 is superseded by "feature flags". This concept enables forward 1416 compatibility against certain future changes in functionality of ZFS 1417 pools. The first read-only compatible "feature flag" for ZFS pools 1418 is named "com.delphix:async_destroy". For more information 1419 read the new zpool-features(5) manual page. 1420 Please refer to the "ZFS notes" section of this file for information 1421 on upgrading boot ZFS pools. 1422 142320120417: 1424 The malloc(3) implementation embedded in libc now uses sources imported 1425 as contrib/jemalloc. The most disruptive API change is to 1426 /etc/malloc.conf. If your system has an old-style /etc/malloc.conf, 1427 delete it prior to installworld, and optionally re-create it using the 1428 new format after rebooting. See malloc.conf(5) for details 1429 (specifically the TUNING section and the "opt.*" entries in the MALLCTL 1430 NAMESPACE section). 1431 143220120328: 1433 Big-endian MIPS TARGET_ARCH values no longer end in "eb". mips64eb 1434 is now spelled mips64. mipsn32eb is now spelled mipsn32. mipseb is 1435 now spelled mips. This is to aid compatibility with third-party 1436 software that expects this naming scheme in uname(3). Little-endian 1437 settings are unchanged. If you are updating a big-endian mips64 machine 1438 from before this change, you may need to set MACHINE_ARCH=mips64 in 1439 your environment before the new build system will recognize your machine. 1440 144120120306: 1442 Disable by default the option VFS_ALLOW_NONMPSAFE for all supported 1443 platforms. 1444 144520120229: 1446 Now unix domain sockets behave "as expected" on nullfs(5). Previously 1447 nullfs(5) did not pass through all behaviours to the underlying layer, 1448 as a result if we bound to a socket on the lower layer we could connect 1449 only to the lower path; if we bound to the upper layer we could connect 1450 only to the upper path. The new behavior is one can connect to both the 1451 lower and the upper paths regardless what layer path one binds to. 1452 145320120211: 1454 The getifaddrs upgrade path broken with 20111215 has been restored. 1455 If you have upgraded in between 20111215 and 20120209 you need to 1456 recompile libc again with your kernel. You still need to recompile 1457 world to be able to configure CARP but this restriction already 1458 comes from 20111215. 1459 146020120114: 1461 The set_rcvar() function has been removed from /etc/rc.subr. All 1462 base and ports rc.d scripts have been updated, so if you have a 1463 port installed with a script in /usr/local/etc/rc.d you can either 1464 hand-edit the rcvar= line, or reinstall the port. 1465 1466 An easy way to handle the mass-update of /etc/rc.d: 1467 rm /etc/rc.d/* && mergemaster -i 1468 146920120109: 1470 panic(9) now stops other CPUs in the SMP systems, disables interrupts 1471 on the current CPU and prevents other threads from running. 1472 This behavior can be reverted using the kern.stop_scheduler_on_panic 1473 tunable/sysctl. 1474 The new behavior can be incompatible with kern.sync_on_panic. 1475 147620111215: 1477 The carp(4) facility has been changed significantly. Configuration 1478 of the CARP protocol via ifconfig(8) has changed, as well as format 1479 of CARP events submitted to devd(8) has changed. See manual pages 1480 for more information. The arpbalance feature of carp(4) is currently 1481 not supported anymore. 1482 1483 Size of struct in_aliasreq, struct in6_aliasreq has changed. User 1484 utilities using SIOCAIFADDR, SIOCAIFADDR_IN6, e.g. ifconfig(8), 1485 need to be recompiled. 1486 148720111122: 1488 The acpi_wmi(4) status device /dev/wmistat has been renamed to 1489 /dev/wmistat0. 1490 149120111108: 1492 The option VFS_ALLOW_NONMPSAFE option has been added in order to 1493 explicitely support non-MPSAFE filesystems. 1494 It is on by default for all supported platform at this present 1495 time. 1496 149720111101: 1498 The broken amd(4) driver has been replaced with esp(4) in the amd64, 1499 i386 and pc98 GENERIC kernel configuration files. 1500 150120110930: 1502 sysinstall has been removed 1503 150420110923: 1505 The stable/9 branch created in subversion. This corresponds to the 1506 RELENG_9 branch in CVS. 1507 1508COMMON ITEMS: 1509 1510 General Notes 1511 ------------- 1512 Avoid using make -j when upgrading. While generally safe, there are 1513 sometimes problems using -j to upgrade. If your upgrade fails with 1514 -j, please try again without -j. From time to time in the past there 1515 have been problems using -j with buildworld and/or installworld. This 1516 is especially true when upgrading between "distant" versions (eg one 1517 that cross a major release boundary or several minor releases, or when 1518 several months have passed on the -current branch). 1519 1520 Sometimes, obscure build problems are the result of environment 1521 poisoning. This can happen because the make utility reads its 1522 environment when searching for values for global variables. To run 1523 your build attempts in an "environmental clean room", prefix all make 1524 commands with 'env -i '. See the env(1) manual page for more details. 1525 1526 When upgrading from one major version to another it is generally best 1527 to upgrade to the latest code in the currently installed branch first, 1528 then do an upgrade to the new branch. This is the best-tested upgrade 1529 path, and has the highest probability of being successful. Please try 1530 this approach before reporting problems with a major version upgrade. 1531 1532 When upgrading a live system, having a root shell around before 1533 installing anything can help undo problems. Not having a root shell 1534 around can lead to problems if pam has changed too much from your 1535 starting point to allow continued authentication after the upgrade. 1536 1537 This file should be read as a log of events. When a later event changes 1538 information of a prior event, the prior event should not be deleted. 1539 Instead, a pointer to the entry with the new information should be 1540 placed in the old entry. Readers of this file should also sanity check 1541 older entries before relying on them blindly. Authors of new entries 1542 should write them with this in mind. 1543 1544 ZFS notes 1545 --------- 1546 When upgrading the boot ZFS pool to a new version, always follow 1547 these two steps: 1548 1549 1.) recompile and reinstall the ZFS boot loader and boot block 1550 (this is part of "make buildworld" and "make installworld") 1551 1552 2.) update the ZFS boot block on your boot drive 1553 1554 The following example updates the ZFS boot block on the first 1555 partition (freebsd-boot) of a GPT partitioned drive ada0: 1556 "gpart bootcode -p /boot/gptzfsboot -i 1 ada0" 1557 1558 Non-boot pools do not need these updates. 1559 1560 To build a kernel 1561 ----------------- 1562 If you are updating from a prior version of FreeBSD (even one just 1563 a few days old), you should follow this procedure. It is the most 1564 failsafe as it uses a /usr/obj tree with a fresh mini-buildworld, 1565 1566 make kernel-toolchain 1567 make -DALWAYS_CHECK_MAKE buildkernel KERNCONF=YOUR_KERNEL_HERE 1568 make -DALWAYS_CHECK_MAKE installkernel KERNCONF=YOUR_KERNEL_HERE 1569 1570 To test a kernel once 1571 --------------------- 1572 If you just want to boot a kernel once (because you are not sure 1573 if it works, or if you want to boot a known bad kernel to provide 1574 debugging information) run 1575 make installkernel KERNCONF=YOUR_KERNEL_HERE KODIR=/boot/testkernel 1576 nextboot -k testkernel 1577 1578 To just build a kernel when you know that it won't mess you up 1579 -------------------------------------------------------------- 1580 This assumes you are already running a CURRENT system. Replace 1581 ${arch} with the architecture of your machine (e.g. "i386", 1582 "arm", "amd64", "ia64", "pc98", "sparc64", "powerpc", "mips", etc). 1583 1584 cd src/sys/${arch}/conf 1585 config KERNEL_NAME_HERE 1586 cd ../compile/KERNEL_NAME_HERE 1587 make depend 1588 make 1589 make install 1590 1591 If this fails, go to the "To build a kernel" section. 1592 1593 To rebuild everything and install it on the current system. 1594 ----------------------------------------------------------- 1595 # Note: sometimes if you are running current you gotta do more than 1596 # is listed here if you are upgrading from a really old current. 1597 1598 <make sure you have good level 0 dumps> 1599 make buildworld 1600 make kernel KERNCONF=YOUR_KERNEL_HERE 1601 [1] 1602 <reboot in single user> [3] 1603 mergemaster -Fp [5] 1604 make installworld 1605 mergemaster -Fi [4] 1606 make delete-old [6] 1607 <reboot> 1608 1609 To cross-install current onto a separate partition 1610 -------------------------------------------------- 1611 # In this approach we use a separate partition to hold 1612 # current's root, 'usr', and 'var' directories. A partition 1613 # holding "/", "/usr" and "/var" should be about 2GB in 1614 # size. 1615 1616 <make sure you have good level 0 dumps> 1617 <boot into -stable> 1618 make buildworld 1619 make buildkernel KERNCONF=YOUR_KERNEL_HERE 1620 <maybe newfs current's root partition> 1621 <mount current's root partition on directory ${CURRENT_ROOT}> 1622 make installworld DESTDIR=${CURRENT_ROOT} -DDB_FROM_SRC 1623 make distribution DESTDIR=${CURRENT_ROOT} # if newfs'd 1624 make installkernel KERNCONF=YOUR_KERNEL_HERE DESTDIR=${CURRENT_ROOT} 1625 cp /etc/fstab ${CURRENT_ROOT}/etc/fstab # if newfs'd 1626 <edit ${CURRENT_ROOT}/etc/fstab to mount "/" from the correct partition> 1627 <reboot into current> 1628 <do a "native" rebuild/install as described in the previous section> 1629 <maybe install compatibility libraries from ports/misc/compat*> 1630 <reboot> 1631 1632 1633 To upgrade in-place from stable to current 1634 ---------------------------------------------- 1635 <make sure you have good level 0 dumps> 1636 make buildworld [9] 1637 make kernel KERNCONF=YOUR_KERNEL_HERE [8] 1638 [1] 1639 <reboot in single user> [3] 1640 mergemaster -Fp [5] 1641 make installworld 1642 mergemaster -Fi [4] 1643 make delete-old [6] 1644 <reboot> 1645 1646 Make sure that you've read the UPDATING file to understand the 1647 tweaks to various things you need. At this point in the life 1648 cycle of current, things change often and you are on your own 1649 to cope. The defaults can also change, so please read ALL of 1650 the UPDATING entries. 1651 1652 Also, if you are tracking -current, you must be subscribed to 1653 freebsd-current@freebsd.org. Make sure that before you update 1654 your sources that you have read and understood all the recent 1655 messages there. If in doubt, please track -stable which has 1656 much fewer pitfalls. 1657 1658 [1] If you have third party modules, such as vmware, you 1659 should disable them at this point so they don't crash your 1660 system on reboot. 1661 1662 [3] From the bootblocks, boot -s, and then do 1663 fsck -p 1664 mount -u / 1665 mount -a 1666 cd src 1667 adjkerntz -i # if CMOS is wall time 1668 Also, when doing a major release upgrade, it is required that 1669 you boot into single user mode to do the installworld. 1670 1671 [4] Note: This step is non-optional. Failure to do this step 1672 can result in a significant reduction in the functionality of the 1673 system. Attempting to do it by hand is not recommended and those 1674 that pursue this avenue should read this file carefully, as well 1675 as the archives of freebsd-current and freebsd-hackers mailing lists 1676 for potential gotchas. The -U option is also useful to consider. 1677 See mergemaster(8) for more information. 1678 1679 [5] Usually this step is a noop. However, from time to time 1680 you may need to do this if you get unknown user in the following 1681 step. It never hurts to do it all the time. You may need to 1682 install a new mergemaster (cd src/usr.sbin/mergemaster && make 1683 install) after the buildworld before this step if you last updated 1684 from current before 20130425 or from -stable before 20130430. 1685 1686 [6] This only deletes old files and directories. Old libraries 1687 can be deleted by "make delete-old-libs", but you have to make 1688 sure that no program is using those libraries anymore. 1689 1690 [8] In order to have a kernel that can run the 4.x binaries needed to 1691 do an installworld, you must include the COMPAT_FREEBSD4 option in 1692 your kernel. Failure to do so may leave you with a system that is 1693 hard to boot to recover. A similar kernel option COMPAT_FREEBSD5 is 1694 required to run the 5.x binaries on more recent kernels. And so on 1695 for COMPAT_FREEBSD6 and COMPAT_FREEBSD7. 1696 1697 Make sure that you merge any new devices from GENERIC since the 1698 last time you updated your kernel config file. 1699 1700 [9] When checking out sources, you must include the -P flag to have 1701 cvs prune empty directories. 1702 1703 If CPUTYPE is defined in your /etc/make.conf, make sure to use the 1704 "?=" instead of the "=" assignment operator, so that buildworld can 1705 override the CPUTYPE if it needs to. 1706 1707 MAKEOBJDIRPREFIX must be defined in an environment variable, and 1708 not on the command line, or in /etc/make.conf. buildworld will 1709 warn if it is improperly defined. 1710FORMAT: 1711 1712This file contains a list, in reverse chronological order, of major 1713breakages in tracking -current. It is not guaranteed to be a complete 1714list of such breakages, and only contains entries since September 23, 2011. 1715If you need to see UPDATING entries from before that date, you will need 1716to fetch an UPDATING file from an older FreeBSD release. 1717 1718Copyright information: 1719 1720Copyright 1998-2009 M.
