1 Updating Information for FreeBSD current users. 2 3This file is maintained and copyrighted by M. Warner Losh <[email protected]>. 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/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 1920190811: 20 Default permissions on the /var/account/acct file (and copies of it 21 rotated by periodic daily scripts) are changed from 0644 to 0640 22 because the file contains sensitive information that should not be 23 world-readable. If the /var/account directory must be created by 24 rc.d/accounting, the mode used is now 0750. Admins who use the 25 accounting feature are encouraged to change the mode of an existing 26 /var/account directory to 0750 or 0700. 27 2820190723: 29 Clang, llvm, lld, lldb, compiler-rt, libc++, libunwind and openmp have 30 been upgraded to 8.0.1. Please see the 20141231 entry below for 31 information about prerequisites and upgrading, if you are not already 32 using clang 3.5.0 or higher. 33 3420190413: 35 Now Clang 8 has been merged (see the 20190412 entry below), the ifunc 36 functionality needed for the RETPOLINE option should work properly 37 again. The RETPOLINE option has been removed from BROKEN_OPTIONS. 38 3920190412: 40 Clang, llvm, lld, lldb, compiler-rt and libc++ have been upgraded to 41 8.0.0. Please see the 20141231 entry below for information about 42 prerequisites and upgrading, if you are not already using clang 3.5.0 43 or higher. 44 4520190307: 46 The RETPOLINE option produces non-functional ifunc-using binaries 47 with Clang 7.0.1, and has been forced off (via BROKEN_OPTIONS). 48 Once Clang 8 is merged it may be enabled again. 49 5020190216: 51 Clang, llvm, lld, lldb, compiler-rt and libc++ have been upgraded to 52 7.0.1. Please see the 20141231 entry below for information about 53 prerequisites and upgrading, if you are not already using clang 3.5.0 54 or higher. 55 5620190226: 57 geom_uzip(4) depends on the new module xz. If geom_uzip is statically 58 compiled into your custom kernel, add 'device xz' statement to the 59 kernel config. 60 6120190214: 62 Iflib is no longer unconditionally compiled into the kernel. Drivers 63 using iflib and statically compiled into the kernel, now require 64 the 'device iflib' config option. For the same drivers loaded as 65 modules on kernels not having 'device iflib', the iflib.ko module 66 is loaded automatically. 67 6820181228: 69 r342561 modifies the NFSv4 server so that it obeys vfs.nfsd.nfs_privport 70 in the same as it is applied to NFSv2 and 3. This implies that NFSv4 71 servers that have vfs.nfsd.nfs_privport set will only allow mounts 72 from clients using a reserved port#. Since both the FreeBSD and Linux 73 NFSv4 clients use reserved port#s by default, this should not affect 74 most NFSv4 mounts. 75 7620181129: 77 On amd64, arm64 and armv7 (architectures that install LLVM's ld.lld 78 linker as /usr/bin/ld) GNU ld is no longer installed as ld.bfd, as 79 it produces broken binaries when ifuncs are in use. Users needing 80 GNU ld should install the binutils port or package. 81 8220181115: 83 The set of CTM commands (ctm, ctm_smail, ctm_rmail, ctm_dequeue) 84 has been converted to a port (misc/ctm) and will be removed from 85 FreeBSD-13. A depreciation warning will be printed to stderr by 86 the ctm command, but the functionality will remain in base for all 87 FreeBSD-12 releases. 88 8920181019: 90 The stable/12 branch has been created in subversion from head 91 revision r339432. 92 9320181015: 94 Ports for the DRM modules have been simplified. Now, amd64 users should 95 just install the drm-kmod port. All others should install 96 drm-legacy-kmod. 97 98 Graphics hardware that's newer than about 2010 usually works with 99 drm-kmod. For hardware older than 2013, however, some users will need 100 to use drm-legacy-kmod if drm-kmod doesn't work for them. Hardware older 101 than 2008 usually only works in drm-legacy-kmod. The graphics team can 102 only commit to hardware made since 2013 due to the complexity of the 103 market and difficulty to test all the older cards effectively. If you 104 have hardware supported by drm-kmod, you are strongly encouraged to use 105 that as you will get better support. 106 107 Other than KPI chasing, drm-legacy-kmod will not be updated. As outlined 108 elsewhere, the drm and drm2 modules will be eliminated from the src base 109 soon (with a limited exception for arm). Please update to the package asap 110 and report any issues to [email protected]. 111 112 Generally, anybody using the drm*-kmod packages should add 113 WITHOUT_DRM_MODULE=t and WITHOUT_DRM2_MODULE=t to avoid nasty 114 cross-threading surprises, especially with automatic driver 115 loading from X11 startup. These will become the defaults in 13-current 116 shortly. 117 11820181012: 119 The ixlv(4) driver has been renamed to iavf(4). As a consequence, 120 custom kernel and module loading configuration files must be updated 121 accordingly. Moreover, interfaces previous presented as ixlvN to the 122 system are now exposed as iavfN and network configuration files must 123 be adjusted as necessary. 124 12520181009: 126 OpenSSL has been updated to version 1.1.1. This update included 127 additional various API changes througout the base system. It is 128 important to rebuild third-party software after upgrading. The value 129 of __FreeBSD_version has been bumped accordingly. 130 13120181006: 132 The legacy DRM modules and drivers have now been added to the loader's 133 module blacklist, in favor of loading them with kld_list in rc.conf(5). 134 The module blacklist may be overridden with the loader.conf(5) 135 'module_blacklist' variable, but loading them via rc.conf(5) is strongly 136 encouraged. 137 13820181002: 139 The cam(4) based nda(4) driver will be used over nvd(4) by default on 140 powerpc64. You may set 'options NVME_USE_NVD=1' in your kernel conf or 141 loader tunable 'hw.nvme.use_nvd=1' if you wish to use the existing 142 driver. Make sure to edit /boot/etc/kboot.conf and fstab to use the 143 nda device name. 144 14520180913: 146 Reproducible build mode is now on by default, in preparation for 147 FreeBSD 12.0. This eliminates build metadata such as the user, 148 host, and time from the kernel (and uname), unless the working tree 149 corresponds to a modified checkout from a version control system. 150 The previous behavior can be obtained by setting the /etc/src.conf 151 knob WITHOUT_REPRODUCIBLE_BUILD. 152 15320180826: 154 The Yarrow CSPRNG has been removed from the kernel as it has not been 155 supported by its designers since at least 2003. Fortuna has been the 156 default since FreeBSD-11. 157 15820180822: 159 devctl freeze/thaw have gone into the tree, the rc scripts have been 160 updated to use them and devmatch has been changed. You should update 161 kernel, userland and rc scripts all at the same time. 162 16320180818: 164 The default interpreter has been switched from 4th to Lua. 165 LOADER_DEFAULT_INTERP, documented in build(7), will override the default 166 interpreter. If you have custom FORTH code you will need to set 167 LOADER_DEFAULT_INTERP=4th (valid values are 4th, lua or simp) in 168 src.conf for the build. This will create default hard links between 169 loader and loader_4th instead of loader and loader_lua, the new default. 170 If you are using UEFI it will create the proper hard link to loader.efi. 171 172 bhyve uses userboot.so. It remains 4th-only until some issues are solved 173 regarding coexisting with multiple versions of FreeBSD are resolved. 174 17520180815: 176 ls(1) now respects the COLORTERM environment variable used in other 177 systems and software to indicate that a colored terminal is both 178 supported and desired. If ls(1) is suddenly emitting colors, they may 179 be disabled again by either removing the unwanted COLORTERM from your 180 environment, or using `ls --color=never`. The ls(1) specific CLICOLOR 181 may not be observed in a future release. 182 18320180808: 184 The default pager for most commands has been changed to "less". To 185 restore the old behavior, set PAGER="more" and MANPAGER="more -s" in 186 your environment. 187 18820180731: 189 The jedec_ts(4) driver has been removed. A superset of its functionality 190 is available in the jedec_dimm(4) driver, and the manpage for that 191 driver includes migration instructions. If you have "device jedec_ts" 192 in your kernel configuration file, it must be removed. 193 19420180730: 195 amd64/GENERIC now has EFI runtime services, EFIRT, enabled by default. 196 This should have no effect if the kernel is booted via BIOS/legacy boot. 197 EFIRT may be disabled via a loader tunable, efi.rt.disabled, if a system 198 has a buggy firmware that prevents a successful boot due to use of 199 runtime services. 200 20120180727: 202 Atmel AT91RM9200 and AT91SAM9, Cavium CNS 11xx and XScale 203 support has been removed from the tree. These ports were 204 obsolete and/or known to be broken for many years. 205 20620180723: 207 loader.efi has been augmented to participate more fully in the 208 UEFI boot manager protocol. loader.efi will now look at the 209 BootXXXX environment variable to determine if a specific kernel 210 or root partition was specified. XXXX is derived from BootCurrent. 211 efibootmgr(8) manages these standard UEFI variables. 212 21320180720: 214 zfsloader's functionality has now been folded into loader. 215 zfsloader is no longer necessary once you've updated your 216 boot blocks. For a transition period, we will install a 217 hardlink for zfsloader to loader to allow a smooth transition 218 until the boot blocks can be updated (hard link because old 219 zfs boot blocks don't understand symlinks). 220 22120180719: 222 ARM64 now have efifb support, if you want to have serial console 223 on your arm64 board when an screen is connected and the bootloader 224 setup a frambuffer for us to use, just add : 225 boot_serial=YES 226 boot_multicons=YES 227 in /boot/loader.conf 228 For Raspberry Pi 3 (RPI) users, this is needed even if you don't have 229 an screen connected as the firmware will setup a framebuffer are that 230 u-boot will expose as an EFI framebuffer. 231 23220180719: 233 New uid:gid added, ntpd:ntpd (123:123). Be sure to run mergemaster 234 or take steps to update /etc/passwd before doing installworld on 235 existing systems. Do not skip the "mergemaster -Fp" step before 236 installworld, as described in the update procedures near the bottom 237 of this document. Also, rc.d/ntpd now starts ntpd(8) as user ntpd 238 if the new mac_ntpd(4) policy is available, unless ntpd_flags or 239 the ntp config file contain options that change file/dir locations. 240 When such options (e.g., "statsdir" or "crypto") are used, ntpd can 241 still be run as non-root by setting ntpd_user=ntpd in rc.conf, after 242 taking steps to ensure that all required files/dirs are accessible 243 by the ntpd user. 244 24520180717: 246 Big endian arm support has been removed. 247 24820180711: 249 The static environment setup in kernel configs is no longer mutually 250 exclusive with the loader(8) environment by default. In order to 251 restore the previous default behavior of disabling the loader(8) 252 environment if a static environment is present, you must specify 253 loader_env.disabled=1 in the static environment. 254 25520180705: 256 The ABI of syscalls used by management tools like sockstat and 257 netstat has been broken to allow 32-bit binaries to work on 258 64-bit kernels without modification. These programs will need 259 to match the kernel in order to function. External programs may 260 require minor modifications to accommodate a change of type in 261 structures from pointers to 64-bit virtual addresses. 262 26320180702: 264 On i386 and amd64 atomics are now inlined. Out of tree modules using 265 atomics will need to be rebuilt. 266 26720180701: 268 The '%I' format in the kern.corefile sysctl limits the number of 269 core files that a process can generate to the number stored in the 270 debug.ncores sysctl. The '%I' format is replaced by the single digit 271 index. Previously, if all indexes were taken the kernel would overwrite 272 only a core file with the highest index in a filename. 273 Currently the system will create a new core file if there is a free 274 index or if all slots are taken it will overwrite the oldest one. 275 27620180630: 277 Clang, llvm, lld, lldb, compiler-rt and libc++ have been upgraded to 278 6.0.1. Please see the 20141231 entry below for information about 279 prerequisites and upgrading, if you are not already using clang 3.5.0 280 or higher. 281 28220180628: 283 r335753 introduced a new quoting method. However, etc/devd/devmatch.conf 284 needed to be changed to work with it. This change was made with r335763 285 and requires a mergemaster / etcupdate / etc to update the installed file. 286 28720180612: 288 r334930 changed the interface between the NFS modules, so they all 289 need to be rebuilt. r335018 did a __FreeBSD_version bump for this. 290 29120180530: 292 As of r334391 lld is the default amd64 system linker; it is installed 293 as /usr/bin/ld. Kernel build workarounds (see 20180510 entry) are no 294 longer necessary. 295 29620180530: 297 The kernel / userland interface for devinfo changed, so you'll 298 need a new kernel and userland as a pair for it to work (rebuilding 299 lib/libdevinfo is all that's required). devinfo and devmatch will 300 not work, but everything else will when there's a mismatch. 301 30220180523: 303 The on-disk format for hwpmc callchain records has changed to include 304 threadid corresponding to a given record. This changes the field offsets 305 and thus requires that libpmcstat be rebuilt before using a kernel 306 later than r334108. 307 30820180517: 309 The vxge(4) driver has been removed. This driver was introduced into 310 HEAD one week before the Exar left the Ethernet market and is not 311 known to be used. If you have device vxge in your kernel config file 312 it must be removed. 313 31420180510: 315 The amd64 kernel now requires a ld that supports ifunc to produce a 316 working kernel, either lld or a newer binutils. lld is built by default 317 on amd64, and the 'buildkernel' target uses it automatically. However, 318 it is not the default linker, so building the kernel the traditional 319 way requires LD=ld.lld on the command line (or LD=/usr/local/bin/ld for 320 binutils port/package). lld will soon be default, and this requirement 321 will go away. 322 323 NOTE: As of r334391 lld is the default system linker on amd64, and no 324 workaround is necessary. 325 32620180508: 327 The nxge(4) driver has been removed. This driver was for PCI-X 10g 328 cards made by s2io/Neterion. The company was aquired by Exar and 329 no longer sells or supports Ethernet products. If you have device 330 nxge in your kernel config file it must be removed. 331 33220180504: 333 The tz database (tzdb) has been updated to 2018e. This version more 334 correctly models time stamps in time zones with negative DST such as 335 Europe/Dublin (from 1971 on), Europe/Prague (1946/7), and 336 Africa/Windhoek (1994/2017). This does not affect the UT offsets, only 337 time zone abbreviations and the tm_isdst flag. 338 33920180502: 340 The ixgb(4) driver has been removed. This driver was for an early and 341 uncommon legacy PCI 10GbE for a single ASIC, Intel 82597EX. Intel 342 quickly shifted to the long lived ixgbe family. If you have device 343 ixgb in your kernel config file it must be removed. 344 34520180501: 346 The lmc(4) driver has been removed. This was a WAN interface 347 card that was already reportedly rare in 2003, and had an ambiguous 348 license. If you have device lmc in your kernel config file it must 349 be removed. 350 35120180413: 352 Support for Arcnet networks has been removed. If you have device 353 arcnet or device cm in your kernel config file they must be 354 removed. 355 35620180411: 357 Support for FDDI networks has been removed. If you have device 358 fddi or device fpa in your kernel config file they must be 359 removed. 360 36120180406: 362 In addition to supporting RFC 3164 formatted messages, the 363 syslogd(8) service is now capable of parsing RFC 5424 formatted 364 log messages. The main benefit of using RFC 5424 is that clients 365 may now send log messages with timestamps containing year numbers, 366 microseconds and time zone offsets. 367 368 Similarly, the syslog(3) C library function has been altered to 369 send RFC 5424 formatted messages to the local system logging 370 daemon. On systems using syslogd(8), this change should have no 371 negative impact, as long as syslogd(8) and the C library are 372 updated at the same time. On systems using a different system 373 logging daemon, it may be necessary to make configuration 374 adjustments, depending on the software used. 375 376 When using syslog-ng, add the 'syslog-protocol' flag to local 377 input sources to enable parsing of RFC 5424 formatted messages: 378 379 source src { 380 unix-dgram("/var/run/log" flags(syslog-protocol)); 381 } 382 383 When using rsyslog, disable the 'SysSock.UseSpecialParser' option 384 of the 'imuxsock' module to let messages be processed by the 385 regular RFC 3164/5424 parsing pipeline: 386 387 module(load="imuxsock" SysSock.UseSpecialParser="off") 388 389 Do note that these changes only affect communication between local 390 applications and syslogd(8). The format that syslogd(8) uses to 391 store messages on disk or forward messages to other systems 392 remains unchanged. syslogd(8) still uses RFC 3164 for these 393 purposes. Options to customize this behaviour will be added in the 394 future. Utilities that process log files stored in /var/log are 395 thus expected to continue to function as before. 396 397 __FreeBSD_version has been incremented to 1200061 to denote this 398 change. 399 40020180328: 401 Support for token ring networks has been removed. If you 402 have "device token" in your kernel config you should remove 403 it. No device drivers supported token ring. 404 40520180323: 406 makefs was modified to be able to tag ISO9660 El Torito boot catalog 407 entries as EFI instead of overloading the i386 tag as done previously. 408 The amd64 mkisoimages.sh script used to build amd64 ISO images for 409 release was updated to use this. This may mean that makefs must be 410 updated before "make cdrom" can be run in the release directory. This 411 should be as simple as: 412 413 $ cd $SRCDIR/usr.sbin/makefs 414 $ make depend all install 415 41620180212: 417 FreeBSD boot loader enhanced with Lua scripting. It's purely opt-in for 418 now by building WITH_LOADER_LUA and WITHOUT_FORTH in /etc/src.conf. 419 Co-existance for the transition period will come shortly. Booting is a 420 complex environment and test coverage for Lua-enabled loaders has been 421 thin, so it would be prudent to assume it might not work and make 422 provisions for backup boot methods. 423 42420180211: 425 devmatch functionality has been turned on in devd. It will automatically 426 load drivers for unattached devices. This may cause unexpected drivers to 427 be loaded. Please report any problems to current@ and [email protected]. 428 42920180114: 430 Clang, llvm, lld, lldb, compiler-rt and libc++ have been upgraded to 431 6.0.0. Please see the 20141231 entry below for information about 432 prerequisites and upgrading, if you are not already using clang 3.5.0 433 or higher. 434 43520180110: 436 LLVM's lld linker is now used as the FreeBSD/amd64 bootstrap linker. 437 This means it is used to link the kernel and userland libraries and 438 executables, but is not yet installed as /usr/bin/ld by default. 439 440 To revert to ld.bfd as the bootstrap linker, in /etc/src.conf set 441 WITHOUT_LLD_BOOTSTRAP=yes 442 44320180110: 444 On i386, pmtimer has been removed. Its functionality has been folded 445 into apm. It was a no-op on ACPI in current for a while now (but was still 446 needed on i386 in FreeBSD 11 and earlier). Users may need to remove it 447 from kernel config files. 448 44920180104: 450 The use of RSS hash from the network card aka flowid has been 451 disabled by default for lagg(4) as it's currently incompatible with 452 the lacp and loadbalance protocols. 453 454 This can be re-enabled by setting the following in loader.conf: 455 net.link.lagg.default_use_flowid="1" 456 45720180102: 458 The SW_WATCHDOG option is no longer necessary to enable the 459 hardclock-based software watchdog if no hardware watchdog is 460 configured. As before, SW_WATCHDOG will cause the software 461 watchdog to be enabled even if a hardware watchdog is configured. 462 46320171215: 464 r326887 fixes the issue described in the 20171214 UPDATING entry. 465 r326888 flips the switch back to building GELI support always. 466 46720171214: 468 r362593 broke ZFS + GELI support for reasons unknown. However, 469 it also broke ZFS support generally, so GELI has been turned off 470 by default as the lesser evil in r326857. If you boot off ZFS and/or 471 GELI, it might not be a good time to update. 472 47320171125: 474 PowerPC users must update loader(8) by rebuilding world before 475 installing a new kernel, as the protocol connecting them has 476 changed. Without the update, loader metadata will not be passed 477 successfully to the kernel and users will have to enter their 478 root partition at the kernel mountroot prompt to continue booting. 479 Newer versions of loader can boot old kernels without issue. 480 48120171110: 482 The LOADER_FIREWIRE_SUPPORT build variable as been renamed to 483 WITH/OUT_LOADER_FIREWIRE. LOADER_{NO_,}GELI_SUPPORT has been renamed 484 to WITH/OUT_LOADER_GELI. 485 48620171106: 487 The naive and non-compliant support of posix_fallocate(2) in ZFS 488 has been removed as of r325320. The system call now returns EINVAL 489 when used on a ZFS file. Although the new behavior complies with the 490 standard, some consumers are not prepared to cope with it. 491 One known victim is lld prior to r325420. 492 49320171102: 494 Building in a FreeBSD src checkout will automatically create object 495 directories now rather than store files in the current directory if 496 'make obj' was not ran. Calling 'make obj' is no longer necessary. 497 This feature can be disabled by setting WITHOUT_AUTO_OBJ=yes in 498 /etc/src-env.conf (not /etc/src.conf), or passing the option in the 499 environment. 500 50120171101: 502 The default MAKEOBJDIR has changed from /usr/obj/<srcdir> for native 503 builds, and /usr/obj/<arch>/<srcdir> for cross-builds, to a unified 504 /usr/obj/<srcdir>/<arch>. This behavior can be changed to the old 505 format by setting WITHOUT_UNIFIED_OBJDIR=yes in /etc/src-env.conf, 506 the environment, or with -DWITHOUT_UNIFIED_OBJDIR when building. 507 The UNIFIED_OBJDIR option is a transitional feature that will be 508 removed for 12.0 release; please migrate to the new format for any 509 tools by looking up the OBJDIR used by 'make -V .OBJDIR' means rather 510 than hardcoding paths. 511 51220171028: 513 The native-xtools target no longer installs the files by default to the 514 OBJDIR. Use the native-xtools-install target with a DESTDIR to install 515 to ${DESTDIR}/${NXTP} where NXTP defaults to /nxb-bin. 516 51720171021: 518 As part of the boot loader infrastructure cleanup, LOADER_*_SUPPORT 519 options are changing from controlling the build if defined / undefined 520 to controlling the build with explicit 'yes' or 'no' values. They will 521 shift to WITH/WITHOUT options to match other options in the system. 522 52320171010: 524 libstand has turned into a private library for sys/boot use only. 525 It is no longer supported as a public interface outside of sys/boot. 526 52720171005: 528 The arm port has split armv6 into armv6 and armv7. armv7 is now 529 a valid TARGET_ARCH/MACHINE_ARCH setting. If you have an armv7 system 530 and are running a kernel from before r324363, you will need to add 531 MACHINE_ARCH=armv7 to 'make buildworld' to do a native build. 532 53320171003: 534 When building multiple kernels using KERNCONF, non-existent KERNCONF 535 files will produce an error and buildkernel will fail. Previously 536 missing KERNCONF files silently failed giving no indication as to 537 why, only to subsequently discover during installkernel that the 538 desired kernel was never built in the first place. 539 54020170912: 541 The default serial number format for CTL LUNs has changed. This will 542 affect users who use /dev/diskid/* device nodes, or whose FibreChannel 543 or iSCSI clients care about their LUNs' serial numbers. Users who 544 require serial number stability should hardcode serial numbers in 545 /etc/ctl.conf . 546 54720170912: 548 For 32-bit arm compiled for hard-float support, soft-floating point 549 binaries now always get their shared libraries from 550 LD_SOFT_LIBRARY_PATH (in the past, this was only used if 551 /usr/libsoft also existed). Only users with a hard-float ld.so, but 552 soft-float everything else should be affected. 553 55420170826: 555 The geli password typed at boot is now hidden. To restore the previous 556 behavior, see geli(8) for configuration options. 557 55820170825: 559 Move PMTUD blackhole counters to TCPSTATS and remove them from bare 560 sysctl values. Minor nit, but requires a rebuild of both world/kernel 561 to complete. 562 56320170814: 564 "make check" behavior (made in ^/head@r295380) has been changed to 565 execute from a limited sandbox, as opposed to executing from 566 ${TESTSDIR}. 567 568 Behavioral changes: 569 - The "beforecheck" and "aftercheck" targets are now specified. 570 - ${CHECKDIR} (added in commit noted above) has been removed. 571 - Legacy behavior can be enabled by setting 572 WITHOUT_MAKE_CHECK_USE_SANDBOX in src.conf(5) or the environment. 573 574 If the limited sandbox mode is enabled, "make check" will execute 575 "make distribution", then install, execute the tests, and clean up the 576 sandbox if successful. 577 578 The "make distribution" and "make install" targets are typically run as 579 root to set appropriate permissions and ownership at installation time. 580 The end-user should set "WITH_INSTALL_AS_USER" in src.conf(5) or the 581 environment if executing "make check" with limited sandbox mode using 582 an unprivileged user. 583 58420170808: 585 Since the switch to GPT disk labels, fsck for UFS/FFS has been 586 unable to automatically find alternate superblocks. As of r322297, 587 the information needed to find alternate superblocks has been 588 moved to the end of the area reserved for the boot block. 589 Filesystems created with a newfs of this vintage or later 590 will create the recovery information. If you have a filesystem 591 created prior to this change and wish to have a recovery block 592 created for your filesystem, you can do so by running fsck in 593 foreground mode (i.e., do not use the -p or -y options). As it 594 starts, fsck will ask ``SAVE DATA TO FIND ALTERNATE SUPERBLOCKS'' 595 to which you should answer yes. 596 59720170728: 598 As of r321665, an NFSv4 server configuration that services 599 Kerberos mounts or clients that do not support the uid/gid in 600 owner/owner_group string capability, must explicitly enable 601 the nfsuserd daemon by adding nfsuserd_enable="YES" to the 602 machine's /etc/rc.conf file. 603 60420170722: 605 Clang, llvm, lldb, compiler-rt and libc++ have been upgraded to 5.0.0. 606 Please see the 20141231 entry below for information about prerequisites 607 and upgrading, if you are not already using clang 3.5.0 or higher. 608 60920170701: 610 WITHOUT_RCMDS is now the default. Set WITH_RCMDS if you need the 611 r-commands (rlogin, rsh, etc.) to be built with the base system. 612 61320170625: 614 The FreeBSD/powerpc platform now uses a 64-bit type for time_t. This is 615 a very major ABI incompatible change, so users of FreeBSD/powerpc must 616 be careful when performing source upgrades. It is best to run 617 'make installworld' from an alternate root system, either a live 618 CD/memory stick, or a temporary root partition. Additionally, all ports 619 must be recompiled. powerpc64 is largely unaffected, except in the case 620 of 32-bit compatibility. All 32-bit binaries will be affected. 621 62220170623: 623 Forward compatibility for the "ino64" project have been committed. This 624 will allow most new binaries to run on older kernels in a limited 625 fashion. This prevents many of the common foot-shooting actions in the 626 upgrade as well as the limited ability to roll back the kernel across 627 the ino64 upgrade. Complicated use cases may not work properly, though 628 enough simpler ones work to allow recovery in most situations. 629 63020170620: 631 Switch back to the BSDL dtc (Device Tree Compiler). Set WITH_GPL_DTC 632 if you require the GPL compiler. 633 63420170618: 635 The internal ABI used for communication between the NFS kernel modules 636 was changed by r320085, so __FreeBSD_version was bumped to 637 ensure all the NFS related modules are updated together. 638 63920170617: 640 The ABI of struct event was changed by extending the data 641 member to 64bit and adding ext fields. For upgrade, same 642 precautions as for the entry 20170523 "ino64" must be 643 followed. 644 64520170531: 646 The GNU roff toolchain has been removed from base. To render manpages 647 which are not supported by mandoc(1), man(1) can fallback on GNU roff 648 from ports (and recommends to install it). 649 To render roff(7) documents, consider using GNU roff from ports or the 650 heirloom doctools roff toolchain from ports via pkg install groff or 651 via pkg install heirloom-doctools. 652 65320170524: 654 The ath(4) and ath_hal(4) modules now build piecemeal to allow for 655 smaller runtime footprint builds. This is useful for embedded systems 656 which only require one chipset support. 657 658 If you load it as a module, make sure this is in /boot/loader.conf: 659 660 if_ath_load="YES" 661 662 This will load the HAL, all chip/RF backends and if_ath_pci. 663 If you have if_ath_pci in /boot/loader.conf, ensure it is after 664 if_ath or it will not load any HAL chipset support. 665 666 If you want to selectively load things (eg on ye cheape ARM/MIPS 667 platforms where RAM is at a premium) you should: 668 669 * load ath_hal 670 * load the chip modules in question 671 * load ath_rate, ath_dfs 672 * load ath_main 673 * load if_ath_pci and/or if_ath_ahb depending upon your particular 674 bus bind type - this is where probe/attach is done. 675 676 For further comments/feedback, poke adrian@ . 677 67820170523: 679 The "ino64" 64-bit inode project has been committed, which extends 680 a number of types to 64 bits. Upgrading in place requires care and 681 adherence to the documented upgrade procedure. 682 683 If using a custom kernel configuration ensure that the 684 COMPAT_FREEBSD11 option is included (as during the upgrade the 685 system will be running the ino64 kernel with the existing world). 686 687 For the safest in-place upgrade begin by removing previous build 688 artifacts via "rm -rf /usr/obj/*". Then, carefully follow the 689 full procedure documented below under the heading "To rebuild 690 everything and install it on the current system." Specifically, 691 a reboot is required after installing the new kernel before 692 installing world. 693 69420170424: 695 The NATM framework including the en(4), fatm(4), hatm(4), and 696 patm(4) devices has been removed. Consumers should plan a 697 migration before the end-of-life date for FreeBSD 11. 698 69920170420: 700 GNU diff has been replaced by a BSD licensed diff. Some features of GNU 701 diff has not been implemented, if those are needed a newer version of 702 GNU diff is available via the diffutils package under the gdiff name. 703 70420170413: 705 As of r316810 for ipfilter, keep frags is no longer assumed when 706 keep state is specified in a rule. r316810 aligns ipfilter with 707 documentation in man pages separating keep frags from keep state. 708 This allows keep state to be specified without forcing keep frags 709 and allows keep frags to be specified independently of keep state. 710 To maintain previous behaviour, also specify keep frags with 711 keep state (as documented in ipf.conf.5). 712 71320170407: 714 arm64 builds now use the base system LLD 4.0.0 linker by default, 715 instead of requiring that the aarch64-binutils port or package be 716 installed. To continue using aarch64-binutils, set 717 CROSS_BINUTILS_PREFIX=/usr/local/aarch64-freebsd/bin . 718 71920170405: 720 The UDP optimization in entry 20160818 that added the sysctl 721 net.inet.udp.require_l2_bcast has been reverted. L2 broadcast 722 packets will no longer be treated as L3 broadcast packets. 723 72420170331: 725 Binds and sends to the loopback addresses, IPv6 and IPv4, will now 726 use any explicitly assigned loopback address available in the jail 727 instead of using the first assigned address of the jail. 728 72920170329: 730 The ctl.ko module no longer implements the iSCSI target frontend: 731 cfiscsi.ko does instead. 732 733 If building cfiscsi.ko as a kernel module, the module can be loaded 734 via one of the following methods: 735 - `cfiscsi_load="YES"` in loader.conf(5). 736 - Add `cfiscsi` to `$kld_list` in rc.conf(5). 737 - ctladm(8)/ctld(8), when compiled with iSCSI support 738 (`WITH_ISCSI=yes` in src.conf(5)) 739 740 Please see cfiscsi(4) for more details. 741 74220170316: 743 The mmcsd.ko module now additionally depends on geom_flashmap.ko. 744 Also, mmc.ko and mmcsd.ko need to be a matching pair built from the 745 same source (previously, the dependency of mmcsd.ko on mmc.ko was 746 missing, but mmcsd.ko now will refuse to load if it is incompatible 747 with mmc.ko). 748 74920170315: 750 The syntax of ipfw(8) named states was changed to avoid ambiguity. 751 If you have used named states in the firewall rules, you need to modify 752 them after installworld and before rebooting. Now named states must 753 be prefixed with colon. 754 75520170311: 756 The old drm (sys/dev/drm/) drivers for i915 and radeon have been 757 removed as the userland we provide cannot use them. The KMS version 758 (sys/dev/drm2) supports the same hardware. 759 76020170302: 761 Clang, llvm, lldb, compiler-rt and libc++ have been upgraded to 4.0.0. 762 Please see the 20141231 entry below for information about prerequisites 763 and upgrading, if you are not already using clang 3.5.0 or higher. 764 76520170221: 766 The code that provides support for ZFS .zfs/ directory functionality 767 has been reimplemented. It's not possible now to create a snapshot 768 by mkdir under .zfs/snapshot/. That should be the only user visible 769 change. 770 77120170216: 772 EISA bus support has been removed. The WITH_EISA option is no longer 773 valid. 774 77520170215: 776 MCA bus support has been removed. 777 77820170127: 779 The WITH_LLD_AS_LD / WITHOUT_LLD_AS_LD build knobs have been renamed 780 WITH_LLD_IS_LD / WITHOUT_LLD_IS_LD, for consistency with CLANG_IS_CC. 781 78220170112: 783 The EM_MULTIQUEUE kernel configuration option is deprecated now that 784 the em(4) driver conforms to iflib specifications. 785 78620170109: 787 The igb(4), em(4) and lem(4) ethernet drivers are now implemented via 788 IFLIB. If you have a custom kernel configuration that excludes em(4) 789 but you use igb(4), you need to re-add em(4) to your custom configuration. 790 79120161217: 792 Clang, llvm, lldb, compiler-rt and libc++ have been upgraded to 3.9.1. 793 Please see the 20141231 entry below for information about prerequisites 794 and upgrading, if you are not already using clang 3.5.0 or higher. 795 79620161124: 797 Clang, llvm, lldb, compiler-rt and libc++ have been upgraded to 3.9.0. 798 Please see the 20141231 entry below for information about prerequisites 799 and upgrading, if you are not already using clang 3.5.0 or higher. 800 80120161119: 802 The layout of the pmap structure has changed for powerpc to put the pmap 803 statistics at the front for all CPU variations. libkvm(3) and all tools 804 that link against it need to be recompiled. 805 80620161030: 807 isl(4) and cyapa(4) drivers now require a new driver, 808 chromebook_platform(4), to work properly on Chromebook-class hardware. 809 On other types of hardware the drivers may need to be configured using 810 device hints. Please see the corresponding manual pages for details. 811 81220161017: 813 The urtwn(4) driver was merged into rtwn(4) and now consists of 814 rtwn(4) main module + rtwn_usb(4) and rtwn_pci(4) bus-specific 815 parts. 816 Also, firmware for RTL8188CE was renamed due to possible name 817 conflict (rtwnrtl8192cU(B) -> rtwnrtl8192cE(B)) 818 81920161015: 820 GNU rcs has been removed from base. It is available as packages: 821 - rcs: Latest GPLv3 GNU rcs version. 822 - rcs57: Copy of the latest version of GNU rcs (GPLv2) before it was 823 removed from base. 824 82520161008: 826 Use of the cc_cdg, cc_chd, cc_hd, or cc_vegas congestion control 827 modules now requires that the kernel configuration contain the 828 TCP_HHOOK option. (This option is included in the GENERIC kernel.) 829 83020161003: 831 The WITHOUT_ELFCOPY_AS_OBJCOPY src.conf(5) knob has been retired. 832 ELF Tool Chain's elfcopy is always installed as /usr/bin/objcopy. 833 83420160924: 835 Relocatable object files with the extension of .So have been renamed 836 to use an extension of .pico instead. The purpose of this change is 837 to avoid a name clash with shared libraries on case-insensitive file 838 systems. On those file systems, foo.So is the same file as foo.so. 839 84020160918: 841 GNU rcs has been turned off by default. It can (temporarily) be built 842 again by adding WITH_RCS knob in src.conf. 843 Otherwise, GNU rcs is available from packages: 844 - rcs: Latest GPLv3 GNU rcs version. 845 - rcs57: Copy of the latest version of GNU rcs (GPLv2) from base. 846 84720160918: 848 The backup_uses_rcs functionality has been removed from rc.subr. 849 85020160908: 851 The queue(3) debugging macro, QUEUE_MACRO_DEBUG, has been split into 852 two separate components, QUEUE_MACRO_DEBUG_TRACE and 853 QUEUE_MACRO_DEBUG_TRASH. Define both for the original 854 QUEUE_MACRO_DEBUG behavior. 855 85620160824: 857 r304787 changed some ioctl interfaces between the iSCSI userspace 858 programs and the kernel. ctladm, ctld, iscsictl, and iscsid must be 859 rebuilt to work with new kernels. __FreeBSD_version has been bumped 860 to 1200005. 861 86220160818: 863 The UDP receive code has been updated to only treat incoming UDP 864 packets that were addressed to an L2 broadcast address as L3 865 broadcast packets. It is not expected that this will affect any 866 standards-conforming UDP application. The new behaviour can be 867 disabled by setting the sysctl net.inet.udp.require_l2_bcast to 868 0. 869 87020160818: 871 Remove the openbsd_poll system call. 872 __FreeBSD_version has been bumped because of this. 873 87420160708: 875 The stable/11 branch has been created from head@r302406. 876 87720160622: 878 The libc stub for the pipe(2) system call has been replaced with 879 a wrapper that calls the pipe2(2) system call and the pipe(2) 880 system call is now only implemented by the kernels that include 881 "options COMPAT_FREEBSD10" in their config file (this is the 882 default). Users should ensure that this option is enabled in 883 their kernel or upgrade userspace to r302092 before upgrading their 884 kernel. 885 88620160527: 887 CAM will now strip leading spaces from SCSI disks' serial numbers. 888 This will affect users who create UFS filesystems on SCSI disks using 889 those disk's diskid device nodes. For example, if /etc/fstab 890 previously contained a line like 891 "/dev/diskid/DISK-%20%20%20%20%20%20%20ABCDEFG0123456", you should 892 change it to "/dev/diskid/DISK-ABCDEFG0123456". Users of geom 893 transforms like gmirror may also be affected. ZFS users should 894 generally be fine. 895 89620160523: 897 The bitstring(3) API has been updated with new functionality and 898 improved performance. But it is binary-incompatible with the old API. 899 Objects built with the new headers may not be linked against objects 900 built with the old headers. 901 90220160520: 903 The brk and sbrk functions have been removed from libc on arm64. 904 Binutils from ports has been updated to not link to these 905 functions and should be updated to the latest version before 906 installing a new libc. 907 90820160517: 909 The armv6 port now defaults to hard float ABI. Limited support 910 for running both hardfloat and soft float on the same system 911 is available using the libraries installed with -DWITH_LIBSOFT. 912 This has only been tested as an upgrade path for installworld 913 and packages may fail or need manual intervention to run. New 914 packages will be needed. 915 916 To update an existing self-hosted armv6hf system, you must add 917 TARGET_ARCH=armv6 on the make command line for both the build 918 and the install steps. 919 92020160510: 921 Kernel modules compiled outside of a kernel build now default to 922 installing to /boot/modules instead of /boot/kernel. Many kernel 923 modules built this way (such as those in ports) already overrode 924 KMODDIR explicitly to install into /boot/modules. However, 925 manually building and installing a module from /sys/modules will 926 now install to /boot/modules instead of /boot/kernel. 927 92820160414: 929 The CAM I/O scheduler has been committed to the kernel. There should be 930 no user visible impact. This does enable NCQ Trim on ada SSDs. While the 931 list of known rogues that claim support for this but actually corrupt 932 data is believed to be complete, be on the lookout for data 933 corruption. The known rogue list is believed to be complete: 934 935 o Crucial MX100, M550 drives with MU01 firmware. 936 o Micron M510 and M550 drives with MU01 firmware. 937 o Micron M500 prior to MU07 firmware 938 o Samsung 830, 840, and 850 all firmwares 939 o FCCT M500 all firmwares 940 941 Crucial has firmware http://www.crucial.com/usa/en/support-ssd-firmware 942 with working NCQ TRIM. For Micron branded drives, see your sales rep for 943 updated firmware. Black listed drives will work correctly because these 944 drives work correctly so long as no NCQ TRIMs are sent to them. Given 945 this list is the same as found in Linux, it's believed there are no 946 other rogues in the market place. All other models from the above 947 vendors work. 948 949 To be safe, if you are at all concerned, you can quirk each of your 950 drives to prevent NCQ from being sent by setting: 951 kern.cam.ada.X.quirks="0x2" 952 in loader.conf. If the drive requires the 4k sector quirk, set the 953 quirks entry to 0x3. 954 95520160330: 956 The FAST_DEPEND build option has been removed and its functionality is 957 now the one true way. The old mkdep(1) style of 'make depend' has 958 been removed. See 20160311 for further details. 959 96020160317: 961 Resource range types have grown from unsigned long to uintmax_t. All 962 drivers, and anything using libdevinfo, need to be recompiled. 963 96420160311: 965 WITH_FAST_DEPEND is now enabled by default for in-tree and out-of-tree 966 builds. It no longer runs mkdep(1) during 'make depend', and the 967 'make depend' stage can safely be skipped now as it is auto ran 968 when building 'make all' and will generate all SRCS and DPSRCS before 969 building anything else. Dependencies are gathered at compile time with 970 -MF flags kept in separate .depend files per object file. Users should 971 run 'make cleandepend' once if using -DNO_CLEAN to clean out older 972 stale .depend files. 973 97420160306: 975 On amd64, clang 3.8.0 can now insert sections of type AMD64_UNWIND into 976 kernel modules. Therefore, if you load any kernel modules at boot time, 977 please install the boot loaders after you install the kernel, but before 978 rebooting, e.g.: 979 980 make buildworld 981 make buildkernel KERNCONF=YOUR_KERNEL_HERE 982 make installkernel KERNCONF=YOUR_KERNEL_HERE 983 make -C sys/boot install 984 <reboot in single user> 985 986 Then follow the usual steps, described in the General Notes section, 987 below. 988 98920160305: 990 Clang, llvm, lldb and compiler-rt have been upgraded to 3.8.0. Please 991 see the 20141231 entry below for information about prerequisites and 992 upgrading, if you are not already using clang 3.5.0 or higher. 993 99420160301: 995 The AIO subsystem is now a standard part of the kernel. The 996 VFS_AIO kernel option and aio.ko kernel module have been removed. 997 Due to stability concerns, asynchronous I/O requests are only 998 permitted on sockets and raw disks by default. To enable 999 asynchronous I/O requests on all file types, set the 1000 vfs.aio.enable_unsafe sysctl to a non-zero value. 1001 100220160226: 1003 The ELF object manipulation tool objcopy is now provided by the 1004 ELF Tool Chain project rather than by GNU binutils. It should be a 1005 drop-in replacement, with the addition of arm64 support. The 1006 (temporary) src.conf knob WITHOUT_ELFCOPY_AS_OBJCOPY knob may be set 1007 to obtain the GNU version if necessary. 1008 100920160129: 1010 Building ZFS pools on top of zvols is prohibited by default. That 1011 feature has never worked safely; it's always been prone to deadlocks. 1012 Using a zvol as the backing store for a VM guest's virtual disk will 1013 still work, even if the guest is using ZFS. Legacy behavior can be 1014 restored by setting vfs.zfs.vol.recursive=1. 1015 101620160119: 1017 The NONE and HPN patches has been removed from OpenSSH. They are 1018 still available in the security/openssh-portable port. 1019 102020160113: 1021 With the addition of ypldap(8), a new _ypldap user is now required 1022 during installworld. "mergemaster -p" can be used to add the user 1023 prior to installworld, as documented in the handbook. 1024 102520151216: 1026 The tftp loader (pxeboot) now uses the option root-path directive. As a 1027 consequence it no longer looks for a pxeboot.4th file on the tftp 1028 server. Instead it uses the regular /boot infrastructure as with the 1029 other loaders. 1030 103120151211: 1032 The code to start recording plug and play data into the modules has 1033 been committed. While the old tools will properly build a new kernel, 1034 a number of warnings about "unknown metadata record 4" will be produced 1035 for an older kldxref. To avoid such warnings, make sure to rebuild 1036 the kernel toolchain (or world). Make sure that you have r292078 or 1037 later when trying to build 292077 or later before rebuilding. 1038 103920151207: 1040 Debug data files are now built by default with 'make buildworld' and 1041 installed with 'make installworld'. This facilitates debugging but 1042 requires more disk space both during the build and for the installed 1043 world. Debug files may be disabled by setting WITHOUT_DEBUG_FILES=yes 1044 in src.conf(5). 1045 104620151130: 1047 r291527 changed the internal interface between the nfsd.ko and 1048 nfscommon.ko modules. As such, they must both be upgraded to-gether. 1049 __FreeBSD_version has been bumped because of this. 1050 105120151108: 1052 Add support for unicode collation strings leads to a change of 1053 order of files listed by ls(1) for example. To get back to the old 1054 behaviour, set LC_COLLATE environment variable to "C". 1055 1056 Databases administrators will need to reindex their databases given 1057 collation results will be different. 1058 1059 Due to a bug in install(1) it is recommended to remove the ancient 1060 locales before running make installworld. 1061 1062 rm -rf /usr/share/locale/* 1063 106420151030: 1065 The OpenSSL has been upgraded to 1.0.2d. Any binaries requiring 1066 libcrypto.so.7 or libssl.so.7 must be recompiled. 1067 106820151020: 1069 Qlogic 24xx/25xx firmware images were updated from 5.5.0 to 7.3.0. 1070 Kernel modules isp_2400_multi and isp_2500_multi were removed and 1071 should be replaced with isp_2400 and isp_2500 modules respectively. 1072 107320151017: 1074 The build previously allowed using 'make -n' to not recurse into 1075 sub-directories while showing what commands would be executed, and 1076 'make -n -n' to recursively show commands. Now 'make -n' will recurse 1077 and 'make -N' will not. 1078 107920151012: 1080 If you specify SENDMAIL_MC or SENDMAIL_CF in make.conf, mergemaster 1081 and etcupdate will now use this file. A custom sendmail.cf is now 1082 updated via this mechanism rather than via installworld. If you had 1083 excluded sendmail.cf in mergemaster.rc or etcupdate.conf, you may 1084 want to remove the exclusion or change it to "always install". 1085 /etc/mail/sendmail.cf is now managed the same way regardless of 1086 whether SENDMAIL_MC/SENDMAIL_CF is used. If you are not using 1087 SENDMAIL_MC/SENDMAIL_CF there should be no change in behavior. 1088 108920151011: 1090 Compatibility shims for legacy ATA device names have been removed. 1091 It includes ATA_STATIC_ID kernel option, kern.cam.ada.legacy_aliases 1092 and kern.geom.raid.legacy_aliases loader tunables, kern.devalias.* 1093 environment variables, /dev/ad* and /dev/ar* symbolic links. 1094 109520151006: 1096 Clang, llvm, lldb, compiler-rt and libc++ have been upgraded to 3.7.0. 1097 Please see the 20141231 entry below for information about prerequisites 1098 and upgrading, if you are not already using clang 3.5.0 or higher. 1099 110020150924: 1101 Kernel debug files have been moved to /usr/lib/debug/boot/kernel/, 1102 and renamed from .symbols to .debug. This reduces the size requirements 1103 on the boot partition or file system and provides consistency with 1104 userland debug files. 1105 1106 When using the supported kernel installation method the 1107 /usr/lib/debug/boot/kernel directory will be renamed (to kernel.old) 1108 as is done with /boot/kernel. 1109 1110 Developers wishing to maintain the historical behavior of installing 1111 debug files in /boot/kernel/ can set KERN_DEBUGDIR="" in src.conf(5). 1112 111320150827: 1114 The wireless drivers had undergone changes that remove the 'parent 1115 interface' from the ifconfig -l output. The rc.d network scripts 1116 used to check presence of a parent interface in the list, so old 1117 scripts would fail to start wireless networking. Thus, etcupdate(3) 1118 or mergemaster(8) run is required after kernel update, to update your 1119 rc.d scripts in /etc. 1120 112120150827: 1122 pf no longer supports 'scrub fragment crop' or 'scrub fragment drop-ovl' 1123 These configurations are now automatically interpreted as 1124 'scrub fragment reassemble'. 1125 112620150817: 1127 Kernel-loadable modules for the random(4) device are back. To use 1128 them, the kernel must have 1129 1130 device random 1131 options RANDOM_LOADABLE 1132 1133 kldload(8) can then be used to load random_fortuna.ko 1134 or random_yarrow.ko. Please note that due to the indirect 1135 function calls that the loadable modules need to provide, 1136 the build-in variants will be slightly more efficient. 1137 1138 The random(4) kernel option RANDOM_DUMMY has been retired due to 1139 unpopularity. It was not all that useful anyway. 1140 114120150813: 1142 The WITHOUT_ELFTOOLCHAIN_TOOLS src.conf(5) knob has been retired. 1143 Control over building the ELF Tool Chain tools is now provided by 1144 the WITHOUT_TOOLCHAIN knob. 1145 114620150810: 1147 The polarity of Pulse Per Second (PPS) capture events with the 1148 uart(4) driver has been corrected. Prior to this change the PPS 1149 "assert" event corresponded to the trailing edge of a positive PPS 1150 pulse and the "clear" event was the leading edge of the next pulse. 1151 1152 As the width of a PPS pulse in a typical GPS receiver is on the 1153 order of 1 millisecond, most users will not notice any significant 1154 difference with this change. 1155 1156 Anyone who has compensated for the historical polarity reversal by 1157 configuring a negative offset equal to the pulse width will need to 1158 remove that workaround. 1159 116020150809: 1161 The default group assigned to /dev/dri entries has been changed 1162 from 'wheel' to 'video' with the id of '44'. If you want to have 1163 access to the dri devices please add yourself to the video group 1164 with: 1165 1166 # pw groupmod video -m $USER 1167 116820150806: 1169 The menu.rc and loader.rc files will now be replaced during 1170 upgrades. Please migrate local changes to menu.rc.local and 1171 loader.rc.local instead. 1172 117320150805: 1174 GNU Binutils versions of addr2line, c++filt, nm, readelf, size, 1175 strings and strip have been removed. The src.conf(5) knob 1176 WITHOUT_ELFTOOLCHAIN_TOOLS no longer provides the binutils tools. 1177 117820150728: 1179 As ZFS requires more kernel stack pages than is the default on some 1180 architectures e.g. i386, it now warns if KSTACK_PAGES is less than 1181 ZFS_MIN_KSTACK_PAGES (which is 4 at the time of writing). 1182 1183 Please consider using 'options KSTACK_PAGES=X' where X is greater 1184 than or equal to ZFS_MIN_KSTACK_PAGES i.e. 4 in such configurations. 1185 118620150706: 1187 sendmail has been updated to 8.15.2. Starting with FreeBSD 11.0 1188 and sendmail 8.15, sendmail uses uncompressed IPv6 addresses by 1189 default, i.e., they will not contain "::". For example, instead 1190 of ::1, it will be 0:0:0:0:0:0:0:1. This permits a zero subnet 1191 to have a more specific match, such as different map entries for 1192 IPv6:0:0 vs IPv6:0. This change requires that configuration 1193 data (including maps, files, classes, custom ruleset, etc.) must 1194 use the same format, so make certain such configuration data is 1195 upgrading. As a very simple check search for patterns like 1196 'IPv6:[0-9a-fA-F:]*::' and 'IPv6::'. To return to the old 1197 behavior, set the m4 option confUSE_COMPRESSED_IPV6_ADDRESSES or 1198 the cf option UseCompressedIPv6Addresses. 1199 120020150630: 1201 The default kernel entropy-processing algorithm is now 1202 Fortuna, replacing Yarrow. 1203 1204 Assuming you have 'device random' in your kernel config 1205 file, the configurations allow a kernel option to override 1206 this default. You may choose *ONE* of: 1207 1208 options RANDOM_YARROW # Legacy /dev/random algorithm. 1209 options RANDOM_DUMMY # Blocking-only driver. 1210 1211 If you have neither, you get Fortuna. For most people, 1212 read no further, Fortuna will give a /dev/random that works 1213 like it always used to, and the difference will be irrelevant. 1214 1215 If you remove 'device random', you get *NO* kernel-processed 1216 entropy at all. This may be acceptable to folks building 1217 embedded systems, but has complications. Carry on reading, 1218 and it is assumed you know what you need. 1219 1220 *PLEASE* read random(4) and random(9) if you are in the 1221 habit of tweaking kernel configs, and/or if you are a member 1222 of the embedded community, wanting specific and not-usual 1223 behaviour from your security subsystems. 1224 1225 NOTE!! If you use RANDOM_DUMMY and/or have no 'device 1226 random', you will NOT have a functioning /dev/random, and 1227 many cryptographic features will not work, including SSH. 1228 You may also find strange behaviour from the random(3) set 1229 of library functions, in particular sranddev(3), srandomdev(3) 1230 and arc4random(3). The reason for this is that the KERN_ARND 1231 sysctl only returns entropy if it thinks it has some to 1232 share, and with RANDOM_DUMMY or no 'device random' this 1233 will never happen. 1234 123520150623: 1236 An additional fix for the issue described in the 20150614 sendmail 1237 entry below has been committed in revision 284717. 1238 123920150616: 1240 FreeBSD's old make (fmake) has been removed from the system. It is 1241 available as the devel/fmake port or via pkg install fmake. 1242 124320150615: 1244 The fix for the issue described in the 20150614 sendmail entry 1245 below has been committed in revision 284436. The work 1246 around described in that entry is no longer needed unless the 1247 default setting is overridden by a confDH_PARAMETERS configuration 1248 setting of '5' or pointing to a 512 bit DH parameter file. 1249 125020150614: 1251 ALLOW_DEPRECATED_ATF_TOOLS/ATFFILE support has been removed from 1252 atf.test.mk (included from bsd.test.mk). Please upgrade devel/atf 1253 and devel/kyua to version 0.20+ and adjust any calling code to work 1254 with Kyuafile and kyua. 1255 125620150614: 1257 The import of openssl to address the FreeBSD-SA-15:10.openssl 1258 security advisory includes a change which rejects handshakes 1259 with DH parameters below 768 bits. sendmail releases prior 1260 to 8.15.2 (not yet released), defaulted to a 512 bit 1261 DH parameter setting for client connections. To work around 1262 this interoperability, sendmail can be configured to use a 1263 2048 bit DH parameter by: 1264 1265 1. Edit /etc/mail/`hostname`.mc 1266 2. If a setting for confDH_PARAMETERS does not exist or 1267 exists and is set to a string beginning with '5', 1268 replace it with '2'. 1269 3. If a setting for confDH_PARAMETERS exists and is set to 1270 a file path, create a new file with: 1271 openssl dhparam -out /path/to/file 2048 1272 4. Rebuild the .cf file: 1273 cd /etc/mail/; make; make install 1274 5. Restart sendmail: 1275 cd /etc/mail/; make restart 1276 1277 A sendmail patch is coming, at which time this file will be 1278 updated. 1279 128020150604: 1281 Generation of legacy formatted entries have been disabled by default 1282 in pwd_mkdb(8), as all base system consumers of the legacy formatted 1283 entries were converted to use the new format by default when the new, 1284 machine independent format have been added and supported since FreeBSD 1285 5.x. 1286 1287 Please see the pwd_mkdb(8) manual page for further details. 1288 128920150525: 1290 Clang and llvm have been upgraded to 3.6.1 release. Please see the 1291 20141231 entry below for information about prerequisites and upgrading, 1292 if you are not already using 3.5.0 or higher. 1293 129420150521: 1295 TI platform code switched to using vendor DTS files and this update 1296 may break existing systems running on Beaglebone, Beaglebone Black, 1297 and Pandaboard: 1298 1299 - dtb files should be regenerated/reinstalled. Filenames are the 1300 same but content is different now 1301 - GPIO addressing was changed, now each GPIO bank (32 pins per bank) 1302 has its own /dev/gpiocX device, e.g. pin 121 on /dev/gpioc0 in old 1303 addressing scheme is now pin 25 on /dev/gpioc3. 1304 - Pandaboard: /etc/ttys should be updated, serial console device is 1305 now /dev/ttyu2, not /dev/ttyu0 1306 130720150501: 1308 soelim(1) from gnu/usr.bin/groff has been replaced by usr.bin/soelim. 1309 If you need the GNU extension from groff soelim(1), install groff 1310 from package: pkg install groff, or via ports: textproc/groff. 1311 131220150423: 1313 chmod, chflags, chown and chgrp now affect symlinks in -R mode as 1314 defined in symlink(7); previously symlinks were silently ignored. 1315 131620150415: 1317 The const qualifier has been removed from iconv(3) to comply with 1318 POSIX. The ports tree is aware of this from r384038 onwards. 1319 132020150416: 1321 Libraries specified by LIBADD in Makefiles must have a corresponding 1322 DPADD_<lib> variable to ensure correct dependencies. This is now 1323 enforced in src.libnames.mk. 1324 132520150324: 1326 From legacy ata(4) driver was removed support for SATA controllers 1327 supported by more functional drivers ahci(4), siis(4) and mvs(4). 1328 Kernel modules ataahci and ataadaptec were removed completely, 1329 replaced by ahci and mvs modules respectively. 1330 133120150315: 1332 Clang, llvm and lldb have been upgraded to 3.6.0 release. Please see 1333 the 20141231 entry below for information about prerequisites and 1334 upgrading, if you are not already using 3.5.0 or higher. 1335 133620150307: 1337 The 32-bit PowerPC kernel has been changed to a position-independent 1338 executable. This can only be booted with a version of loader(8) 1339 newer than January 31, 2015, so make sure to update both world and 1340 kernel before rebooting. 1341 134220150217: 1343 If you are running a -CURRENT kernel since r273872 (Oct 30th, 2014), 1344 but before r278950, the RNG was not seeded properly. Immediately 1345 upgrade the kernel to r278950 or later and regenerate any keys (e.g. 1346 ssh keys or openssl keys) that were generated w/ a kernel from that 1347 range. This does not affect programs that directly used /dev/random 1348 or /dev/urandom. All userland uses of arc4random(3) are affected. 1349 135020150210: 1351 The autofs(4) ABI was changed in order to restore binary compatibility 1352 with 10.1-RELEASE. The automountd(8) daemon needs to be rebuilt to work 1353 with the new kernel. 1354 135520150131: 1356 The powerpc64 kernel has been changed to a position-independent 1357 executable. This can only be booted with a new version of loader(8), 1358 so make sure to update both world and kernel before rebooting. 1359 136020150118: 1361 Clang and llvm have been upgraded to 3.5.1 release. This is a bugfix 1362 only release, no new features have been added. Please see the 20141231 1363 entry below for information about prerequisites and upgrading, if you 1364 are not already using 3.5.0. 1365 136620150107: 1367 ELF tools addr2line, elfcopy (strip), nm, size, and strings are now 1368 taken from the ELF Tool Chain project rather than GNU binutils. They 1369 should be drop-in replacements, with the addition of arm64 support. 1370 The WITHOUT_ELFTOOLCHAIN_TOOLS= knob may be used to obtain the 1371 binutils tools, if necessary. See 20150805 for updated information. 1372 137320150105: 1374 The default Unbound configuration now enables remote control 1375 using a local socket. Users who have already enabled the 1376 local_unbound service should regenerate their configuration 1377 by running "service local_unbound setup" as root. 1378 137920150102: 1380 The GNU texinfo and GNU info pages have been removed. 1381 To be able to view GNU info pages please install texinfo from ports. 1382 138320141231: 1384 Clang, llvm and lldb have been upgraded to 3.5.0 release. 1385 1386 As of this release, a prerequisite for building clang, llvm and lldb is 1387 a C++11 capable compiler and C++11 standard library. This means that to 1388 be able to successfully build the cross-tools stage of buildworld, with 1389 clang as the bootstrap compiler, your system compiler or cross compiler 1390 should either be clang 3.3 or later, or gcc 4.8 or later, and your 1391 system C++ library should be libc++, or libdstdc++ from gcc 4.8 or 1392 later. 1393 1394 On any standard FreeBSD 10.x or 11.x installation, where clang and 1395 libc++ are on by default (that is, on x86 or arm), this should work out 1396 of the box. 1397 1398 On 9.x installations where clang is enabled by default, e.g. on x86 and 1399 powerpc, libc++ will not be enabled by default, so libc++ should be 1400 built (with clang) and installed first. If both clang and libc++ are 1401 missing, build clang first, then use it to build libc++. 1402 1403 On 8.x and earlier installations, upgrade to 9.x first, and then follow 1404 the instructions for 9.x above. 1405 1406 Sparc64 and mips users are unaffected, as they still use gcc 4.2.1 by 1407 default, and do not build clang. 1408 1409 Many embedded systems are resource constrained, and will not be able to 1410 build clang in a reasonable time, or in some cases at all. In those 1411 cases, cross building bootable systems on amd64 is a workaround. 1412 1413 This new version of clang introduces a number of new warnings, of which 1414 the following are most likely to appear: 1415 1416 -Wabsolute-value 1417 1418 This warns in two cases, for both C and C++: 1419 * When the code is trying to take the absolute value of an unsigned 1420 quantity, which is effectively a no-op, and almost never what was 1421 intended. The code should be fixed, if at all possible. If you are 1422 sure that the unsigned quantity can be safely cast to signed, without 1423 loss of information or undefined behavior, you can add an explicit 1424 cast, or disable the warning. 1425 1426 * When the code is trying to take an absolute value, but the called 1427 abs() variant is for the wrong type, which can lead to truncation. 1428 If you want to disable the warning instead of fixing the code, please 1429 make sure that truncation will not occur, or it might lead to unwanted 1430 side-effects. 1431 1432 -Wtautological-undefined-compare and 1433 -Wundefined-bool-conversion 1434 1435 These warn when C++ code is trying to compare 'this' against NULL, while 1436 'this' should never be NULL in well-defined C++ code. However, there is 1437 some legacy (pre C++11) code out there, which actively abuses this 1438 feature, which was less strictly defined in previous C++ versions. 1439 1440 Squid and openjdk do this, for example. The warning can be turned off 1441 for C++98 and earlier, but compiling the code in C++11 mode might result 1442 in unexpected behavior; for example, the parts of the program that are 1443 unreachable could be optimized away. 1444 144520141222: 1446 The old NFS client and server (kernel options NFSCLIENT, NFSSERVER) 1447 kernel sources have been removed. The .h files remain, since some 1448 utilities include them. This will need to be fixed later. 1449 If "mount -t oldnfs ..." is attempted, it will fail. 1450 If the "-o" option on mountd(8), nfsd(8) or nfsstat(1) is used, 1451 the utilities will report errors. 1452 145320141121: 1454 The handling of LOCAL_LIB_DIRS has been altered to skip addition of 1455 directories to top level SUBDIR variable when their parent 1456 directory is included in LOCAL_DIRS. Users with build systems with 1457 such hierarchies and without SUBDIR entries in the parent 1458 directory Makefiles should add them or add the directories to 1459 LOCAL_DIRS. 1460 146120141109: 1462 faith(4) and faithd(8) have been removed from the base system. Faith 1463 has been obsolete for a very long time. 1464 146520141104: 1466 vt(4), the new console driver, is enabled by default. It brings 1467 support for Unicode and double-width characters, as well as 1468 support for UEFI and integration with the KMS kernel video 1469 drivers. 1470 1471 You may need to update your console settings in /etc/rc.conf, 1472 most probably the keymap. During boot, /etc/rc.d/syscons will 1473 indicate what you need to do. 1474 1475 vt(4) still has issues and lacks some features compared to 1476 syscons(4). See the wiki for up-to-date information: 1477 https://wiki.freebsd.org/Newcons 1478 1479 If you want to keep using syscons(4), you can do so by adding 1480 the following line to /boot/loader.conf: 1481 kern.vty=sc 1482 148320141102: 1484 pjdfstest has been integrated into kyua as an opt-in test suite. 1485 Please see share/doc/pjdfstest/README for more details on how to 1486 execute it. 1487 148820141009: 1489 gperf has been removed from the base system for architectures 1490 that use clang. Ports that require gperf will obtain it from the 1491 devel/gperf port. 1492 149320140923: 1494 pjdfstest has been moved from tools/regression/pjdfstest to 1495 contrib/pjdfstest . 1496 149720140922: 1498 At svn r271982, The default linux compat kernel ABI has been adjusted 1499 to 2.6.18 in support of the linux-c6 compat ports infrastructure 1500 update. If you wish to continue using the linux-f10 compat ports, 1501 add compat.linux.osrelease=2.6.16 to your local sysctl.conf. Users are 1502 encouraged to update their linux-compat packages to linux-c6 during 1503 their next update cycle. 1504 150520140729: 1506 The ofwfb driver, used to provide a graphics console on PowerPC when 1507 using vt(4), no longer allows mmap() of all physical memory. This 1508 will prevent Xorg on PowerPC with some ATI graphics cards from 1509 initializing properly unless x11-servers/xorg-server is updated to 1510 1.12.4_8 or newer. 1511 151220140723: 1513 The xdev targets have been converted to using TARGET and 1514 TARGET_ARCH instead of XDEV and XDEV_ARCH. 1515 151620140719: 1517 The default unbound configuration has been modified to address 1518 issues with reverse lookups on networks that use private 1519 address ranges. If you use the local_unbound service, run 1520 "service local_unbound setup" as root to regenerate your 1521 configuration, then "service local_unbound reload" to load the 1522 new configuration. 1523 152420140709: 1525 The GNU texinfo and GNU info pages are not built and installed 1526 anymore, WITH_INFO knob has been added to allow to built and install 1527 them again. 1528 UPDATE: see 20150102 entry on texinfo's removal 1529 153020140708: 1531 The GNU readline library is now an INTERNALLIB - that is, it is 1532 statically linked into consumers (GDB and variants) in the base 1533 system, and the shared library is no longer installed. The 1534 devel/readline port is available for third party software that 1535 requires readline. 1536 153720140702: 1538 The Itanium architecture (ia64) has been removed from the list of 1539 known architectures. This is the first step in the removal of the 1540 architecture. 1541 154220140701: 1543 Commit r268115 has added NFSv4.1 server support, merged from 1544 projects/nfsv4.1-server. Since this includes changes to the 1545 internal interfaces between the NFS related modules, a full 1546 build of the kernel and modules will be necessary. 1547 __FreeBSD_version has been bumped. 1548 154920140629: 1550 The WITHOUT_VT_SUPPORT kernel config knob has been renamed 1551 WITHOUT_VT. (The other _SUPPORT knobs have a consistent meaning 1552 which differs from the behaviour controlled by this knob.) 1553 155420140619: 1555 Maximal length of the serial number in CTL was increased from 16 to 1556 64 chars, that breaks ABI. All CTL-related tools, such as ctladm 1557 and ctld, need to be rebuilt to work with a new kernel. 1558 155920140606: 1560 The libatf-c and libatf-c++ major versions were downgraded to 0 and 1561 1 respectively to match the upstream numbers. They were out of 1562 sync because, when they were originally added to FreeBSD, the 1563 upstream versions were not respected. These libraries are private 1564 and not yet built by default, so renumbering them should be a 1565 non-issue. However, unclean source trees will yield broken test 1566 programs once the operator executes "make delete-old-libs" after a 1567 "make installworld". 1568 1569 Additionally, the atf-sh binary was made private by moving it into 1570 /usr/libexec/. Already-built shell test programs will keep the 1571 path to the old binary so they will break after "make delete-old" 1572 is run. 1573 1574 If you are using WITH_TESTS=yes (not the default), wipe the object 1575 tree and rebuild from scratch to prevent spurious test failures. 1576 This is only needed once: the misnumbered libraries and misplaced 1577 binaries have been added to OptionalObsoleteFiles.inc so they will 1578 be removed during a clean upgrade. 1579 158020140512: 1581 Clang and llvm have been upgraded to 3.4.1 release. 1582 158320140508: 1584 We bogusly installed src.opts.mk in /usr/share/mk. This file should 1585 be removed to avoid issues in the future (and has been added to 1586 ObsoleteFiles.inc). 1587 158820140505: 1589 /etc/src.conf now affects only builds of the FreeBSD src tree. In the 1590 past, it affected all builds that used the bsd.*.mk files. The old 1591 behavior was a bug, but people may have relied upon it. To get this 1592 behavior back, you can .include /etc/src.conf from /etc/make.conf 1593 (which is still global and isn't changed). This also changes the 1594 behavior of incremental builds inside the tree of individual 1595 directories. Set MAKESYSPATH to ".../share/mk" to do that. 1596 Although this has survived make universe and some upgrade scenarios, 1597 other upgrade scenarios may have broken. At least one form of 1598 temporary breakage was fixed with MAKESYSPATH settings for buildworld 1599 as well... In cases where MAKESYSPATH isn't working with this 1600 setting, you'll need to set it to the full path to your tree. 1601 1602 One side effect of all this cleaning up is that bsd.compiler.mk 1603 is no longer implicitly included by bsd.own.mk. If you wish to 1604 use COMPILER_TYPE, you must now explicitly include bsd.compiler.mk 1605 as well. 1606 160720140430: 1608 The lindev device has been removed since /dev/full has been made a 1609 standard device. __FreeBSD_version has been bumped. 1610 161120140424: 1612 The knob WITHOUT_VI was added to the base system, which controls 1613 building ex(1), vi(1), etc. Older releases of FreeBSD required ex(1) 1614 in order to reorder files share/termcap and didn't build ex(1) as a 1615 build tool, so building/installing with WITH_VI is highly advised for 1616 build hosts for older releases. 1617 1618 This issue has been fixed in stable/9 and stable/10 in r277022 and 1619 r276991, respectively. 1620 162120140418: 1622 The YES_HESIOD knob has been removed. It has been obsolete for 1623 a decade. Please move to using WITH_HESIOD instead or your builds 1624 will silently lack HESIOD. 1625 162620140405: 1627 The uart(4) driver has been changed with respect to its handling 1628 of the low-level console. Previously the uart(4) driver prevented 1629 any process from changing the baudrate or the CLOCAL and HUPCL 1630 control flags. By removing the restrictions, operators can make 1631 changes to the serial console port without having to reboot. 1632 However, when getty(8) is started on the serial device that is 1633 associated with the low-level console, a misconfigured terminal 1634 line in /etc/ttys will now have a real impact. 1635 Before upgrading the kernel, make sure that /etc/ttys has the 1636 serial console device configured as 3wire without baudrate to 1637 preserve the previous behaviour. E.g: 1638 ttyu0 "/usr/libexec/getty 3wire" vt100 on secure 1639 164020140306: 1641 Support for libwrap (TCP wrappers) in rpcbind was disabled by default 1642 to improve performance. To re-enable it, if needed, run rpcbind 1643 with command line option -W. 1644 164520140226: 1646 Switched back to the GPL dtc compiler due to updates in the upstream 1647 dts files not being supported by the BSDL dtc compiler. You will need 1648 to rebuild your kernel toolchain to pick up the new compiler. Core dumps 1649 may result while building dtb files during a kernel build if you fail 1650 to do so. Set WITHOUT_GPL_DTC if you require the BSDL compiler. 1651 165220140216: 1653 Clang and llvm have been upgraded to 3.4 release. 1654 165520140216: 1656 The nve(4) driver has been removed. Please use the nfe(4) driver 1657 for NVIDIA nForce MCP Ethernet adapters instead. 1658 165920140212: 1660 An ABI incompatibility crept into the libc++ 3.4 import in r261283. 1661 This could cause certain C++ applications using shared libraries built 1662 against the previous version of libc++ to crash. The incompatibility 1663 has now been fixed, but any C++ applications or shared libraries built 1664 between r261283 and r261801 should be recompiled. 1665 166620140204: 1667 OpenSSH will now ignore errors caused by kernel lacking of Capsicum 1668 capability mode support. Please note that enabling the feature in 1669 kernel is still highly recommended. 1670 167120140131: 1672 OpenSSH is now built with sandbox support, and will use sandbox as 1673 the default privilege separation method. This requires Capsicum 1674 capability mode support in kernel. 1675 167620140128: 1677 The libelf and libdwarf libraries have been updated to newer 1678 versions from upstream. Shared library version numbers for 1679 these two libraries were bumped. Any ports or binaries 1680 requiring these two libraries should be recompiled. 1681 __FreeBSD_version is bumped to 1100006. 1682 168320140110: 1684 If a Makefile in a tests/ directory was auto-generating a Kyuafile 1685 instead of providing an explicit one, this would prevent such 1686 Makefile from providing its own Kyuafile in the future during 1687 NO_CLEAN builds. This has been fixed in the Makefiles but manual 1688 intervention is needed to clean an objdir if you use NO_CLEAN: 1689 # find /usr/obj -name Kyuafile | xargs rm -f 1690 169120131213: 1692 The behavior of gss_pseudo_random() for the krb5 mechanism 1693 has changed, for applications requesting a longer random string 1694 than produced by the underlying enctype's pseudo-random() function. 1695 In particular, the random string produced from a session key of 1696 enctype aes256-cts-hmac-sha1-96 or aes256-cts-hmac-sha1-96 will 1697 be different at the 17th octet and later, after this change. 1698 The counter used in the PRF+ construction is now encoded as a 1699 big-endian integer in accordance with RFC 4402. 1700 __FreeBSD_version is bumped to 1100004. 1701 170220131108: 1703 The WITHOUT_ATF build knob has been removed and its functionality 1704 has been subsumed into the more generic WITHOUT_TESTS. If you were 1705 using the former to disable the build of the ATF libraries, you 1706 should change your settings to use the latter. 1707 170820131025: 1709 The default version of mtree is nmtree which is obtained from 1710 NetBSD. The output is generally the same, but may vary 1711 slightly. If you found you need identical output adding 1712 "-F freebsd9" to the command line should do the trick. For the 1713 time being, the old mtree is available as fmtree. 1714 171520131014: 1716 libbsdyml has been renamed to libyaml and moved to /usr/lib/private. 1717 This will break ports-mgmt/pkg. Rebuild the port, or upgrade to pkg 1718 1.1.4_8 and verify bsdyml not linked in, before running "make 1719 delete-old-libs": 1720 # make -C /usr/ports/ports-mgmt/pkg build deinstall install clean 1721 or 1722 # pkg install pkg; ldd /usr/local/sbin/pkg | grep bsdyml 1723 172420131010: 1725 The stable/10 branch has been created in subversion from head 1726 revision r256279. 1727 1728COMMON ITEMS: 1729 1730 General Notes 1731 ------------- 1732 Avoid using make -j when upgrading. While generally safe, there are 1733 sometimes problems using -j to upgrade. If your upgrade fails with 1734 -j, please try again without -j. From time to time in the past there 1735 have been problems using -j with buildworld and/or installworld. This 1736 is especially true when upgrading between "distant" versions (eg one 1737 that cross a major release boundary or several minor releases, or when 1738 several months have passed on the -current branch). 1739 1740 Sometimes, obscure build problems are the result of environment 1741 poisoning. This can happen because the make utility reads its 1742 environment when searching for values for global variables. To run 1743 your build attempts in an "environmental clean room", prefix all make 1744 commands with 'env -i '. See the env(1) manual page for more details. 1745 1746 When upgrading from one major version to another it is generally best to 1747 upgrade to the latest code in the currently installed branch first, then 1748 do an upgrade to the new branch. This is the best-tested upgrade path, 1749 and has the highest probability of being successful. Please try this 1750 approach if you encounter problems with a major version upgrade. Since 1751 the stable 4.x branch point, one has generally been able to upgrade from 1752 anywhere in the most recent stable branch to head / current (or even the 1753 last couple of stable branches). See the top of this file when there's 1754 an exception. 1755 1756 When upgrading a live system, having a root shell around before 1757 installing anything can help undo problems. Not having a root shell 1758 around can lead to problems if pam has changed too much from your 1759 starting point to allow continued authentication after the upgrade. 1760 1761 This file should be read as a log of events. When a later event changes 1762 information of a prior event, the prior event should not be deleted. 1763 Instead, a pointer to the entry with the new information should be 1764 placed in the old entry. Readers of this file should also sanity check 1765 older entries before relying on them blindly. Authors of new entries 1766 should write them with this in mind. 1767 1768 ZFS notes 1769 --------- 1770 When upgrading the boot ZFS pool to a new version, always follow 1771 these two steps: 1772 1773 1.) recompile and reinstall the ZFS boot loader and boot block 1774 (this is part of "make buildworld" and "make installworld") 1775 1776 2.) update the ZFS boot block on your boot drive 1777 1778 The following example updates the ZFS boot block on the first 1779 partition (freebsd-boot) of a GPT partitioned drive ada0: 1780 "gpart bootcode -p /boot/gptzfsboot -i 1 ada0" 1781 1782 Non-boot pools do not need these updates. 1783 1784 To build a kernel 1785 ----------------- 1786 If you are updating from a prior version of FreeBSD (even one just 1787 a few days old), you should follow this procedure. It is the most 1788 failsafe as it uses a /usr/obj tree with a fresh mini-buildworld, 1789 1790 make kernel-toolchain 1791 make -DALWAYS_CHECK_MAKE buildkernel KERNCONF=YOUR_KERNEL_HERE 1792 make -DALWAYS_CHECK_MAKE installkernel KERNCONF=YOUR_KERNEL_HERE 1793 1794 To test a kernel once 1795 --------------------- 1796 If you just want to boot a kernel once (because you are not sure 1797 if it works, or if you want to boot a known bad kernel to provide 1798 debugging information) run 1799 make installkernel KERNCONF=YOUR_KERNEL_HERE KODIR=/boot/testkernel 1800 nextboot -k testkernel 1801 1802 To rebuild everything and install it on the current system. 1803 ----------------------------------------------------------- 1804 # Note: sometimes if you are running current you gotta do more than 1805 # is listed here if you are upgrading from a really old current. 1806 1807 <make sure you have good level 0 dumps> 1808 make buildworld 1809 make buildkernel KERNCONF=YOUR_KERNEL_HERE 1810 make installkernel KERNCONF=YOUR_KERNEL_HERE 1811 [1] 1812 <reboot in single user> [3] 1813 mergemaster -Fp [5] 1814 make installworld 1815 mergemaster -Fi [4] 1816 make delete-old [6] 1817 <reboot> 1818 1819 To cross-install current onto a separate partition 1820 -------------------------------------------------- 1821 # In this approach we use a separate partition to hold 1822 # current's root, 'usr', and 'var' directories. A partition 1823 # holding "/", "/usr" and "/var" should be about 2GB in 1824 # size. 1825 1826 <make sure you have good level 0 dumps> 1827 <boot into -stable> 1828 make buildworld 1829 make buildkernel KERNCONF=YOUR_KERNEL_HERE 1830 <maybe newfs current's root partition> 1831 <mount current's root partition on directory ${CURRENT_ROOT}> 1832 make installworld DESTDIR=${CURRENT_ROOT} -DDB_FROM_SRC 1833 make distribution DESTDIR=${CURRENT_ROOT} # if newfs'd 1834 make installkernel KERNCONF=YOUR_KERNEL_HERE DESTDIR=${CURRENT_ROOT} 1835 cp /etc/fstab ${CURRENT_ROOT}/etc/fstab # if newfs'd 1836 <edit ${CURRENT_ROOT}/etc/fstab to mount "/" from the correct partition> 1837 <reboot into current> 1838 <do a "native" rebuild/install as described in the previous section> 1839 <maybe install compatibility libraries from ports/misc/compat*> 1840 <reboot> 1841 1842 1843 To upgrade in-place from stable to current 1844 ---------------------------------------------- 1845 <make sure you have good level 0 dumps> 1846 make buildworld [9] 1847 make buildkernel KERNCONF=YOUR_KERNEL_HERE [8] 1848 make installkernel KERNCONF=YOUR_KERNEL_HERE 1849 [1] 1850 <reboot in single user> [3] 1851 mergemaster -Fp [5] 1852 make installworld 1853 mergemaster -Fi [4] 1854 make delete-old [6] 1855 <reboot> 1856 1857 Make sure that you've read the UPDATING file to understand the 1858 tweaks to various things you need. At this point in the life 1859 cycle of current, things change often and you are on your own 1860 to cope. The defaults can also change, so please read ALL of 1861 the UPDATING entries. 1862 1863 Also, if you are tracking -current, you must be subscribed to 1864 [email protected]. Make sure that before you update 1865 your sources that you have read and understood all the recent 1866 messages there. If in doubt, please track -stable which has 1867 much fewer pitfalls. 1868 1869 [1] If you have third party modules, such as vmware, you 1870 should disable them at this point so they don't crash your 1871 system on reboot. 1872 1873 [3] From the bootblocks, boot -s, and then do 1874 fsck -p 1875 mount -u / 1876 mount -a 1877 cd src 1878 adjkerntz -i # if CMOS is wall time 1879 Also, when doing a major release upgrade, it is required that 1880 you boot into single user mode to do the installworld. 1881 1882 [4] Note: This step is non-optional. Failure to do this step 1883 can result in a significant reduction in the functionality of the 1884 system. Attempting to do it by hand is not recommended and those 1885 that pursue this avenue should read this file carefully, as well 1886 as the archives of freebsd-current and freebsd-hackers mailing lists 1887 for potential gotchas. The -U option is also useful to consider. 1888 See mergemaster(8) for more information. 1889 1890 [5] Usually this step is a no-op. However, from time to time 1891 you may need to do this if you get unknown user in the following 1892 step. It never hurts to do it all the time. You may need to 1893 install a new mergemaster (cd src/usr.sbin/mergemaster && make 1894 install) after the buildworld before this step if you last updated 1895 from current before 20130425 or from -stable before 20130430. 1896 1897 [6] This only deletes old files and directories. Old libraries 1898 can be deleted by "make delete-old-libs", but you have to make 1899 sure that no program is using those libraries anymore. 1900 1901 [8] The new kernel must be able to run existing binaries used by 1902 an installworld. When upgrading across major versions, the new 1903 kernel's configuration must include the correct COMPAT_FREEBSD<n> 1904 option for existing binaries (e.g. COMPAT_FREEBSD11 to run 11.x 1905 binaries). Failure to do so may leave you with a system that is 1906 hard to boot to recover. A GENERIC kernel will include suitable 1907 compatibility options to run binaries from older branches. 1908 1909 Make sure that you merge any new devices from GENERIC since the 1910 last time you updated your kernel config file. 1911 1912 [9] If CPUTYPE is defined in your /etc/make.conf, make sure to use the 1913 "?=" instead of the "=" assignment operator, so that buildworld can 1914 override the CPUTYPE if it needs to. 1915 1916 MAKEOBJDIRPREFIX must be defined in an environment variable, and 1917 not on the command line, or in /etc/make.conf. buildworld will 1918 warn if it is improperly defined. 1919FORMAT: 1920 1921This file contains a list, in reverse chronological order, of major 1922breakages in tracking -current. It is not guaranteed to be a complete 1923list of such breakages, and only contains entries since September 23, 2011. 1924If you need to see UPDATING entries from before that date, you will need 1925to fetch an UPDATING file from an older FreeBSD release. 1926 1927Copyright information: 1928 1929Copyright 1998-2009 M.
