1 Updating 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/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 19NOTE TO PEOPLE WHO THINK THAT FreeBSD 13.x IS SLOW: 20 FreeBSD 13.x has many debugging features turned on, in both the kernel 21 and userland. These features attempt to detect incorrect use of 22 system primitives, and encourage loud failure through extra sanity 23 checking and fail stop semantics. They also substantially impact 24 system performance. If you want to do performance measurement, 25 benchmarking, and optimization, you'll want to turn them off. This 26 includes various WITNESS- related kernel options, INVARIANTS, malloc 27 debugging flags in userland, and various verbose features in the 28 kernel. Many developers choose to disable these features on build 29 machines to maximize performance. (To completely disable malloc 30 debugging, define MALLOC_PRODUCTION in /etc/make.conf, or to merely 31 disable the most expensive debugging functionality run 32 "ln -s 'abort:false,junk:false' /etc/malloc.conf".) 33 3420181230: 35 r342635 changes the way efibootmgr(8) works by requiring users to add 36 the -b (bootnum) parameter for commands where the bootnum was previously 37 specified with each option. For example 'efibootmgr -B 0001' is now 38 'efibootmgr -B -b 0001'. 39 4020181220: 41 r342286 modifies the NFSv4 server so that it obeys vfs.nfsd.nfs_privport 42 in the same as it is applied to NFSv2 and 3. This implies that NFSv4 43 servers that have vfs.nfsd.nfs_privport set will only allow mounts 44 from clients using a reserved port#. Since both the FreeBSD and Linux 45 NFSv4 clients use reserved port#s by default, this should not affect 46 most NFSv4 mounts. 47 4820181219: 49 The XLP config has been removed. We can't support 64-bit atomics in this 50 kernel because it is running in 32-bit mode. XLP users must transition 51 to running a 64-bit kernel (XLP64 or XLPN32). 52 53 The mips GXEMUL support has been removed from FreeBSD. MALTA* + qemu is 54 the preferred emulator today and we don't need two different ones. 55 56 The old sibyte / swarm / Broadcom BCM1250 support has been 57 removed from the mips port. 58 5920181211: 60 Clang, llvm, lld, lldb, compiler-rt and libc++ have been upgraded to 61 7.0.1. Please see the 20141231 entry below for information about 62 prerequisites and upgrading, if you are not already using clang 3.5.0 63 or higher. 64 6520181211: 66 Remove the timed and netdate programs from the base tree. Setting 67 the time with these deamons has been obsolete for over a decade. 68 6920181126: 70 On amd64, arm64 and armv7 (architectures that install LLVM's ld.lld 71 linker as /usr/bin/ld) GNU ld is no longer installed as ld.bfd, as 72 it produces broken binaries when ifuncs are in use. Users needing 73 GNU ld should install the binutils port or package. 74 7520181123: 76 The BSD crtbegin and crtend code has been enabled by default. It has 77 had extensive testing on amd64, arm64, and i386. It can be disabled 78 by building a world with -DWITHOUT_BSD_CRTBEGIN. 79 8020181115: 81 The set of CTM commands (ctm, ctm_smail, ctm_rmail, ctm_dequeue) 82 has been converted to a port (misc/ctm) and will be removed from 83 FreeBSD-13. It is available as a package (ctm) for all supported 84 FreeBSD versions. 85 8620181110: 87 The default newsyslog.conf(5) file has been changed to only include 88 files in /etc/newsyslog.conf.d/ and /usr/local/etc/newsyslog.conf.d/ if 89 the filenames end in '.conf' and do not begin with a '.'. 90 91 You should check the configuration files in these two directories match 92 this naming convention. You can verify which configuration files are 93 being included using the command: 94 $ newsyslog -Nrv 95 9620181015: 97 Ports for the DRM modules have been simplified. Now, amd64 users should 98 just install the drm-kmod port. All others should install 99 drm-legacy-kmod. 100 101 Graphics hardware that's newer than about 2010 usually works with 102 drm-kmod. For hardware older than 2013, however, some users will need 103 to use drm-legacy-kmod if drm-kmod doesn't work for them. Hardware older 104 than 2008 usually only works in drm-legacy-kmod. The graphics team can 105 only commit to hardware made since 2013 due to the complexity of the 106 market and difficulty to test all the older cards effectively. If you 107 have hardware supported by drm-kmod, you are strongly encouraged to use 108 that as you will get better support. 109 110 Other than KPI chasing, drm-legacy-kmod will not be updated. As outlined 111 elsewhere, the drm and drm2 modules will be eliminated from the src base 112 soon (with a limited exception for arm). Please update to the package asap 113 and report any issues to x11@freebsd.org. 114 115 Generally, anybody using the drm*-kmod packages should add 116 WITHOUT_DRM_MODULE=t and WITHOUT_DRM2_MODULE=t to avoid nasty 117 cross-threading surprises, especially with automatic driver 118 loading from X11 startup. These will become the defaults in 13-current 119 shortly. 120 12120181012: 122 The ixlv(4) driver has been renamed to iavf(4). As a consequence, 123 custom kernel and module loading configuration files must be updated 124 accordingly. Moreover, interfaces previous presented as ixlvN to the 125 system are now exposed as iavfN and network configuration files must 126 be adjusted as necessary. 127 12820181009: 129 OpenSSL has been updated to version 1.1.1. This update included 130 additional various API changes througout the base system. It is 131 important to rebuild third-party software after upgrading. The value 132 of __FreeBSD_version has been bumped accordingly. 133 13420181006: 135 The legacy DRM modules and drivers have now been added to the loader's 136 module blacklist, in favor of loading them with kld_list in rc.conf(5). 137 The module blacklist may be overridden with the loader.conf(5) 138 'module_blacklist' variable, but loading them via rc.conf(5) is strongly 139 encouraged. 140 14120181002: 142 The cam(4) based nda(4) driver will be used over nvd(4) by default on 143 powerpc64. You may set 'options NVME_USE_NVD=1' in your kernel conf or 144 loader tunable 'hw.nvme.use_nvd=1' if you wish to use the existing 145 driver. Make sure to edit /boot/etc/kboot.conf and fstab to use the 146 nda device name. 147 14820180913: 149 Reproducible build mode is now on by default, in preparation for 150 FreeBSD 12.0. This eliminates build metadata such as the user, 151 host, and time from the kernel (and uname), unless the working tree 152 corresponds to a modified checkout from a version control system. 153 The previous behavior can be obtained by setting the /etc/src.conf 154 knob WITHOUT_REPRODUCIBLE_BUILD. 155 15620180826: 157 The Yarrow CSPRNG has been removed from the kernel as it has not been 158 supported by its designers since at least 2003. Fortuna has been the 159 default since FreeBSD-11. 160 16120180822: 162 devctl freeze/thaw have gone into the tree, the rc scripts have been 163 updated to use them and devmatch has been changed. You should update 164 kernel, userland and rc scripts all at the same time. 165 16620180818: 167 The default interpreter has been switched from 4th to Lua. 168 LOADER_DEFAULT_INTERP, documented in build(7), will override the default 169 interpreter. If you have custom FORTH code you will need to set 170 LOADER_DEFAULT_INTERP=4th (valid values are 4th, lua or simp) in 171 src.conf for the build. This will create default hard links between 172 loader and loader_4th instead of loader and loader_lua, the new default. 173 If you are using UEFI it will create the proper hard link to loader.efi. 174 175 bhyve uses userboot.so. It remains 4th-only until some issues are solved 176 regarding coexisting with multiple versions of FreeBSD are resolved. 177 17820180815: 179 ls(1) now respects the COLORTERM environment variable used in other 180 systems and software to indicate that a colored terminal is both 181 supported and desired. If ls(1) is suddenly emitting colors, they may 182 be disabled again by either removing the unwanted COLORTERM from your 183 environment, or using `ls --color=never`. The ls(1) specific CLICOLOR 184 may not be observed in a future release. 185 18620180808: 187 The default pager for most commands has been changed to "less". To 188 restore the old behavior, set PAGER="more" and MANPAGER="more -s" in 189 your environment. 190 19120180731: 192 The jedec_ts(4) driver has been removed. A superset of its functionality 193 is available in the jedec_dimm(4) driver, and the manpage for that 194 driver includes migration instructions. If you have "device jedec_ts" 195 in your kernel configuration file, it must be removed. 196 19720180730: 198 amd64/GENERIC now has EFI runtime services, EFIRT, enabled by default. 199 This should have no effect if the kernel is booted via BIOS/legacy boot. 200 EFIRT may be disabled via a loader tunable, efi.rt.disabled, if a system 201 has a buggy firmware that prevents a successful boot due to use of 202 runtime services. 203 20420180727: 205 Atmel AT91RM9200 and AT91SAM9, Cavium CNS 11xx and XScale 206 support has been removed from the tree. These ports were 207 obsolete and/or known to be broken for many years. 208 20920180723: 210 loader.efi has been augmented to participate more fully in the 211 UEFI boot manager protocol. loader.efi will now look at the 212 BootXXXX environment variable to determine if a specific kernel 213 or root partition was specified. XXXX is derived from BootCurrent. 214 efibootmgr(8) manages these standard UEFI variables. 215 21620180720: 217 zfsloader's functionality has now been folded into loader. 218 zfsloader is no longer necessary once you've updated your 219 boot blocks. For a transition period, we will install a 220 hardlink for zfsloader to loader to allow a smooth transition 221 until the boot blocks can be updated (hard link because old 222 zfs boot blocks don't understand symlinks). 223 22420180719: 225 ARM64 now have efifb support, if you want to have serial console 226 on your arm64 board when an screen is connected and the bootloader 227 setup a frambuffer for us to use, just add : 228 boot_serial=YES 229 boot_multicons=YES 230 in /boot/loader.conf 231 For Raspberry Pi 3 (RPI) users, this is needed even if you don't have 232 an screen connected as the firmware will setup a framebuffer are that 233 u-boot will expose as an EFI framebuffer. 234 23520180719: 236 New uid:gid added, ntpd:ntpd (123:123). Be sure to run mergemaster 237 or take steps to update /etc/passwd before doing installworld on 238 existing systems. Do not skip the "mergemaster -Fp" step before 239 installworld, as described in the update procedures near the bottom 240 of this document. Also, rc.d/ntpd now starts ntpd(8) as user ntpd 241 if the new mac_ntpd(4) policy is available, unless ntpd_flags or 242 the ntp config file contain options that change file/dir locations. 243 When such options (e.g., "statsdir" or "crypto") are used, ntpd can 244 still be run as non-root by setting ntpd_user=ntpd in rc.conf, after 245 taking steps to ensure that all required files/dirs are accessible 246 by the ntpd user. 247 24820180717: 249 Big endian arm support has been removed. 250 25120180711: 252 The static environment setup in kernel configs is no longer mutually 253 exclusive with the loader(8) environment by default. In order to 254 restore the previous default behavior of disabling the loader(8) 255 environment if a static environment is present, you must specify 256 loader_env.disabled=1 in the static environment. 257 25820180705: 259 The ABI of syscalls used by management tools like sockstat and 260 netstat has been broken to allow 32-bit binaries to work on 261 64-bit kernels without modification. These programs will need 262 to match the kernel in order to function. External programs may 263 require minor modifications to accommodate a change of type in 264 structures from pointers to 64-bit virtual addresses. 265 26620180702: 267 On i386 and amd64 atomics are now inlined. Out of tree modules using 268 atomics will need to be rebuilt. 269 27020180701: 271 The '%I' format in the kern.corefile sysctl limits the number of 272 core files that a process can generate to the number stored in the 273 debug.ncores sysctl. The '%I' format is replaced by the single digit 274 index. Previously, if all indexes were taken the kernel would overwrite 275 only a core file with the highest index in a filename. 276 Currently the system will create a new core file if there is a free 277 index or if all slots are taken it will overwrite the oldest one. 278 27920180630: 280 Clang, llvm, lld, lldb, compiler-rt and libc++ have been upgraded to 281 6.0.1. Please see the 20141231 entry below for information about 282 prerequisites and upgrading, if you are not already using clang 3.5.0 283 or higher. 284 28520180628: 286 r335753 introduced a new quoting method. However, etc/devd/devmatch.conf 287 needed to be changed to work with it. This change was made with r335763 288 and requires a mergemaster / etcupdate / etc to update the installed file. 289 29020180612: 291 r334930 changed the interface between the NFS modules, so they all 292 need to be rebuilt. r335018 did a __FreeBSD_version bump for this. 293 29420180530: 295 As of r334391 lld is the default amd64 system linker; it is installed 296 as /usr/bin/ld. Kernel build workarounds (see 20180510 entry) are no 297 longer necessary. 298 29920180530: 300 The kernel / userland interface for devinfo changed, so you'll 301 need a new kernel and userland as a pair for it to work (rebuilding 302 lib/libdevinfo is all that's required). devinfo and devmatch will 303 not work, but everything else will when there's a mismatch. 304 30520180523: 306 The on-disk format for hwpmc callchain records has changed to include 307 threadid corresponding to a given record. This changes the field offsets 308 and thus requires that libpmcstat be rebuilt before using a kernel 309 later than r334108. 310 31120180517: 312 The vxge(4) driver has been removed. This driver was introduced into 313 HEAD one week before the Exar left the Ethernet market and is not 314 known to be used. If you have device vxge in your kernel config file 315 it must be removed. 316 31720180510: 318 The amd64 kernel now requires a ld that supports ifunc to produce a 319 working kernel, either lld or a newer binutils. lld is built by default 320 on amd64, and the 'buildkernel' target uses it automatically. However, 321 it is not the default linker, so building the kernel the traditional 322 way requires LD=ld.lld on the command line (or LD=/usr/local/bin/ld for 323 binutils port/package). lld will soon be default, and this requirement 324 will go away. 325 326 NOTE: As of r334391 lld is the default system linker on amd64, and no 327 workaround is necessary. 328 32920180508: 330 The nxge(4) driver has been removed. This driver was for PCI-X 10g 331 cards made by s2io/Neterion. The company was aquired by Exar and 332 no longer sells or supports Ethernet products. If you have device 333 nxge in your kernel config file it must be removed. 334 33520180504: 336 The tz database (tzdb) has been updated to 2018e. This version more 337 correctly models time stamps in time zones with negative DST such as 338 Europe/Dublin (from 1971 on), Europe/Prague (1946/7), and 339 Africa/Windhoek (1994/2017). This does not affect the UT offsets, only 340 time zone abbreviations and the tm_isdst flag. 341 34220180502: 343 The ixgb(4) driver has been removed. This driver was for an early and 344 uncommon legacy PCI 10GbE for a single ASIC, Intel 82597EX. Intel 345 quickly shifted to the long lived ixgbe family. If you have device 346 ixgb in your kernel config file it must be removed. 347 34820180501: 349 The lmc(4) driver has been removed. This was a WAN interface 350 card that was already reportedly rare in 2003, and had an ambiguous 351 license. If you have device lmc in your kernel config file it must 352 be removed. 353 35420180413: 355 Support for Arcnet networks has been removed. If you have device 356 arcnet or device cm in your kernel config file they must be 357 removed. 358 35920180411: 360 Support for FDDI networks has been removed. If you have device 361 fddi or device fpa in your kernel config file they must be 362 removed. 363 36420180406: 365 In addition to supporting RFC 3164 formatted messages, the 366 syslogd(8) service is now capable of parsing RFC 5424 formatted 367 log messages. The main benefit of using RFC 5424 is that clients 368 may now send log messages with timestamps containing year numbers, 369 microseconds and time zone offsets. 370 371 Similarly, the syslog(3) C library function has been altered to 372 send RFC 5424 formatted messages to the local system logging 373 daemon. On systems using syslogd(8), this change should have no 374 negative impact, as long as syslogd(8) and the C library are 375 updated at the same time. On systems using a different system 376 logging daemon, it may be necessary to make configuration 377 adjustments, depending on the software used. 378 379 When using syslog-ng, add the 'syslog-protocol' flag to local 380 input sources to enable parsing of RFC 5424 formatted messages: 381 382 source src { 383 unix-dgram("/var/run/log" flags(syslog-protocol)); 384 } 385 386 When using rsyslog, disable the 'SysSock.UseSpecialParser' option 387 of the 'imuxsock' module to let messages be processed by the 388 regular RFC 3164/5424 parsing pipeline: 389 390 module(load="imuxsock" SysSock.UseSpecialParser="off") 391 392 Do note that these changes only affect communication between local 393 applications and syslogd(8). The format that syslogd(8) uses to 394 store messages on disk or forward messages to other systems 395 remains unchanged. syslogd(8) still uses RFC 3164 for these 396 purposes. Options to customize this behaviour will be added in the 397 future. Utilities that process log files stored in /var/log are 398 thus expected to continue to function as before. 399 400 __FreeBSD_version has been incremented to 1200061 to denote this 401 change. 402 40320180328: 404 Support for token ring networks has been removed. If you 405 have "device token" in your kernel config you should remove 406 it. No device drivers supported token ring. 407 40820180323: 409 makefs was modified to be able to tag ISO9660 El Torito boot catalog 410 entries as EFI instead of overloading the i386 tag as done previously. 411 The amd64 mkisoimages.sh script used to build amd64 ISO images for 412 release was updated to use this. This may mean that makefs must be 413 updated before "make cdrom" can be run in the release directory. This 414 should be as simple as: 415 416 $ cd $SRCDIR/usr.sbin/makefs 417 $ make depend all install 418 41920180212: 420 FreeBSD boot loader enhanced with Lua scripting. It's purely opt-in for 421 now by building WITH_LOADER_LUA and WITHOUT_FORTH in /etc/src.conf. 422 Co-existance for the transition period will come shortly. Booting is a 423 complex environment and test coverage for Lua-enabled loaders has been 424 thin, so it would be prudent to assume it might not work and make 425 provisions for backup boot methods. 426 42720180211: 428 devmatch functionality has been turned on in devd. It will automatically 429 load drivers for unattached devices. This may cause unexpected drivers to 430 be loaded. Please report any problems to current@ and imp@freebsd.org. 431 43220180114: 433 Clang, llvm, lld, lldb, compiler-rt and libc++ have been upgraded to 434 6.0.0. Please see the 20141231 entry below for information about 435 prerequisites and upgrading, if you are not already using clang 3.5.0 436 or higher. 437 43820180110: 439 LLVM's lld linker is now used as the FreeBSD/amd64 bootstrap linker. 440 This means it is used to link the kernel and userland libraries and 441 executables, but is not yet installed as /usr/bin/ld by default. 442 443 To revert to ld.bfd as the bootstrap linker, in /etc/src.conf set 444 WITHOUT_LLD_BOOTSTRAP=yes 445 44620180110: 447 On i386, pmtimer has been removed. Its functionality has been folded 448 into apm. It was a no-op on ACPI in current for a while now (but was still 449 needed on i386 in FreeBSD 11 and earlier). Users may need to remove it 450 from kernel config files. 451 45220180104: 453 The use of RSS hash from the network card aka flowid has been 454 disabled by default for lagg(4) as it's currently incompatible with 455 the lacp and loadbalance protocols. 456 457 This can be re-enabled by setting the following in loader.conf: 458 net.link.lagg.default_use_flowid="1" 459 46020180102: 461 The SW_WATCHDOG option is no longer necessary to enable the 462 hardclock-based software watchdog if no hardware watchdog is 463 configured. As before, SW_WATCHDOG will cause the software 464 watchdog to be enabled even if a hardware watchdog is configured. 465 46620171215: 467 r326887 fixes the issue described in the 20171214 UPDATING entry. 468 r326888 flips the switch back to building GELI support always. 469 47020171214: 471 r362593 broke ZFS + GELI support for reasons unknown. However, 472 it also broke ZFS support generally, so GELI has been turned off 473 by default as the lesser evil in r326857. If you boot off ZFS and/or 474 GELI, it might not be a good time to update. 475 47620171125: 477 PowerPC users must update loader(8) by rebuilding world before 478 installing a new kernel, as the protocol connecting them has 479 changed. Without the update, loader metadata will not be passed 480 successfully to the kernel and users will have to enter their 481 root partition at the kernel mountroot prompt to continue booting. 482 Newer versions of loader can boot old kernels without issue. 483 48420171110: 485 The LOADER_FIREWIRE_SUPPORT build variable as been renamed to 486 WITH/OUT_LOADER_FIREWIRE. LOADER_{NO_,}GELI_SUPPORT has been renamed 487 to WITH/OUT_LOADER_GELI. 488 48920171106: 490 The naive and non-compliant support of posix_fallocate(2) in ZFS 491 has been removed as of r325320. The system call now returns EINVAL 492 when used on a ZFS file. Although the new behavior complies with the 493 standard, some consumers are not prepared to cope with it. 494 One known victim is lld prior to r325420. 495 49620171102: 497 Building in a FreeBSD src checkout will automatically create object 498 directories now rather than store files in the current directory if 499 'make obj' was not ran. Calling 'make obj' is no longer necessary. 500 This feature can be disabled by setting WITHOUT_AUTO_OBJ=yes in 501 /etc/src-env.conf (not /etc/src.conf), or passing the option in the 502 environment. 503 50420171101: 505 The default MAKEOBJDIR has changed from /usr/obj/<srcdir> for native 506 builds, and /usr/obj/<arch>/<srcdir> for cross-builds, to a unified 507 /usr/obj/<srcdir>/<arch>. This behavior can be changed to the old 508 format by setting WITHOUT_UNIFIED_OBJDIR=yes in /etc/src-env.conf, 509 the environment, or with -DWITHOUT_UNIFIED_OBJDIR when building. 510 The UNIFIED_OBJDIR option is a transitional feature that will be 511 removed for 12.0 release; please migrate to the new format for any 512 tools by looking up the OBJDIR used by 'make -V .OBJDIR' means rather 513 than hardcoding paths. 514 51520171028: 516 The native-xtools target no longer installs the files by default to the 517 OBJDIR. Use the native-xtools-install target with a DESTDIR to install 518 to ${DESTDIR}/${NXTP} where NXTP defaults to /nxb-bin. 519 52020171021: 521 As part of the boot loader infrastructure cleanup, LOADER_*_SUPPORT 522 options are changing from controlling the build if defined / undefined 523 to controlling the build with explicit 'yes' or 'no' values. They will 524 shift to WITH/WITHOUT options to match other options in the system. 525 52620171010: 527 libstand has turned into a private library for sys/boot use only. 528 It is no longer supported as a public interface outside of sys/boot. 529 53020171005: 531 The arm port has split armv6 into armv6 and armv7. armv7 is now 532 a valid TARGET_ARCH/MACHINE_ARCH setting. If you have an armv7 system 533 and are running a kernel from before r324363, you will need to add 534 MACHINE_ARCH=armv7 to 'make buildworld' to do a native build. 535 53620171003: 537 When building multiple kernels using KERNCONF, non-existent KERNCONF 538 files will produce an error and buildkernel will fail. Previously 539 missing KERNCONF files silently failed giving no indication as to 540 why, only to subsequently discover during installkernel that the 541 desired kernel was never built in the first place. 542 54320170912: 544 The default serial number format for CTL LUNs has changed. This will 545 affect users who use /dev/diskid/* device nodes, or whose FibreChannel 546 or iSCSI clients care about their LUNs' serial numbers. Users who 547 require serial number stability should hardcode serial numbers in 548 /etc/ctl.conf . 549 55020170912: 551 For 32-bit arm compiled for hard-float support, soft-floating point 552 binaries now always get their shared libraries from 553 LD_SOFT_LIBRARY_PATH (in the past, this was only used if 554 /usr/libsoft also existed). Only users with a hard-float ld.so, but 555 soft-float everything else should be affected. 556 55720170826: 558 The geli password typed at boot is now hidden. To restore the previous 559 behavior, see geli(8) for configuration options. 560 56120170825: 562 Move PMTUD blackhole counters to TCPSTATS and remove them from bare 563 sysctl values. Minor nit, but requires a rebuild of both world/kernel 564 to complete. 565 56620170814: 567 "make check" behavior (made in ^/head@r295380) has been changed to 568 execute from a limited sandbox, as opposed to executing from 569 ${TESTSDIR}. 570 571 Behavioral changes: 572 - The "beforecheck" and "aftercheck" targets are now specified. 573 - ${CHECKDIR} (added in commit noted above) has been removed. 574 - Legacy behavior can be enabled by setting 575 WITHOUT_MAKE_CHECK_USE_SANDBOX in src.conf(5) or the environment. 576 577 If the limited sandbox mode is enabled, "make check" will execute 578 "make distribution", then install, execute the tests, and clean up the 579 sandbox if successful. 580 581 The "make distribution" and "make install" targets are typically run as 582 root to set appropriate permissions and ownership at installation time. 583 The end-user should set "WITH_INSTALL_AS_USER" in src.conf(5) or the 584 environment if executing "make check" with limited sandbox mode using 585 an unprivileged user. 586 58720170808: 588 Since the switch to GPT disk labels, fsck for UFS/FFS has been 589 unable to automatically find alternate superblocks. As of r322297, 590 the information needed to find alternate superblocks has been 591 moved to the end of the area reserved for the boot block. 592 Filesystems created with a newfs of this vintage or later 593 will create the recovery information. If you have a filesystem 594 created prior to this change and wish to have a recovery block 595 created for your filesystem, you can do so by running fsck in 596 foreground mode (i.e., do not use the -p or -y options). As it 597 starts, fsck will ask ``SAVE DATA TO FIND ALTERNATE SUPERBLOCKS'' 598 to which you should answer yes. 599 60020170728: 601 As of r321665, an NFSv4 server configuration that services 602 Kerberos mounts or clients that do not support the uid/gid in 603 owner/owner_group string capability, must explicitly enable 604 the nfsuserd daemon by adding nfsuserd_enable="YES" to the 605 machine's /etc/rc.conf file. 606 60720170722: 608 Clang, llvm, lldb, compiler-rt and libc++ have been upgraded to 5.0.0. 609 Please see the 20141231 entry below for information about prerequisites 610 and upgrading, if you are not already using clang 3.5.0 or higher. 611 61220170701: 613 WITHOUT_RCMDS is now the default. Set WITH_RCMDS if you need the 614 r-commands (rlogin, rsh, etc.) to be built with the base system. 615 61620170625: 617 The FreeBSD/powerpc platform now uses a 64-bit type for time_t. This is 618 a very major ABI incompatible change, so users of FreeBSD/powerpc must 619 be careful when performing source upgrades. It is best to run 620 'make installworld' from an alternate root system, either a live 621 CD/memory stick, or a temporary root partition. Additionally, all ports 622 must be recompiled. powerpc64 is largely unaffected, except in the case 623 of 32-bit compatibility. All 32-bit binaries will be affected. 624 62520170623: 626 Forward compatibility for the "ino64" project have been committed. This 627 will allow most new binaries to run on older kernels in a limited 628 fashion. This prevents many of the common foot-shooting actions in the 629 upgrade as well as the limited ability to roll back the kernel across 630 the ino64 upgrade. Complicated use cases may not work properly, though 631 enough simpler ones work to allow recovery in most situations. 632 63320170620: 634 Switch back to the BSDL dtc (Device Tree Compiler). Set WITH_GPL_DTC 635 if you require the GPL compiler. 636 63720170618: 638 The internal ABI used for communication between the NFS kernel modules 639 was changed by r320085, so __FreeBSD_version was bumped to 640 ensure all the NFS related modules are updated together. 641 64220170617: 643 The ABI of struct event was changed by extending the data 644 member to 64bit and adding ext fields. For upgrade, same 645 precautions as for the entry 20170523 "ino64" must be 646 followed. 647 64820170531: 649 The GNU roff toolchain has been removed from base. To render manpages 650 which are not supported by mandoc(1), man(1) can fallback on GNU roff 651 from ports (and recommends to install it). 652 To render roff(7) documents, consider using GNU roff from ports or the 653 heirloom doctools roff toolchain from ports via pkg install groff or 654 via pkg install heirloom-doctools. 655 65620170524: 657 The ath(4) and ath_hal(4) modules now build piecemeal to allow for 658 smaller runtime footprint builds. This is useful for embedded systems 659 which only require one chipset support. 660 661 If you load it as a module, make sure this is in /boot/loader.conf: 662 663 if_ath_load="YES" 664 665 This will load the HAL, all chip/RF backends and if_ath_pci. 666 If you have if_ath_pci in /boot/loader.conf, ensure it is after 667 if_ath or it will not load any HAL chipset support. 668 669 If you want to selectively load things (eg on ye cheape ARM/MIPS 670 platforms where RAM is at a premium) you should: 671 672 * load ath_hal 673 * load the chip modules in question 674 * load ath_rate, ath_dfs 675 * load ath_main 676 * load if_ath_pci and/or if_ath_ahb depending upon your particular 677 bus bind type - this is where probe/attach is done. 678 679 For further comments/feedback, poke adrian@ . 680 68120170523: 682 The "ino64" 64-bit inode project has been committed, which extends 683 a number of types to 64 bits. Upgrading in place requires care and 684 adherence to the documented upgrade procedure. 685 686 If using a custom kernel configuration ensure that the 687 COMPAT_FREEBSD11 option is included (as during the upgrade the 688 system will be running the ino64 kernel with the existing world). 689 690 For the safest in-place upgrade begin by removing previous build 691 artifacts via "rm -rf /usr/obj/*". Then, carefully follow the 692 full procedure documented below under the heading "To rebuild 693 everything and install it on the current system." Specifically, 694 a reboot is required after installing the new kernel before 695 installing world. 696 69720170424: 698 The NATM framework including the en(4), fatm(4), hatm(4), and 699 patm(4) devices has been removed. Consumers should plan a 700 migration before the end-of-life date for FreeBSD 11. 701 70220170420: 703 GNU diff has been replaced by a BSD licensed diff. Some features of GNU 704 diff has not been implemented, if those are needed a newer version of 705 GNU diff is available via the diffutils package under the gdiff name. 706 70720170413: 708 As of r316810 for ipfilter, keep frags is no longer assumed when 709 keep state is specified in a rule. r316810 aligns ipfilter with 710 documentation in man pages separating keep frags from keep state. 711 This allows keep state to be specified without forcing keep frags 712 and allows keep frags to be specified independently of keep state. 713 To maintain previous behaviour, also specify keep frags with 714 keep state (as documented in ipf.conf.5). 715 71620170407: 717 arm64 builds now use the base system LLD 4.0.0 linker by default, 718 instead of requiring that the aarch64-binutils port or package be 719 installed. To continue using aarch64-binutils, set 720 CROSS_BINUTILS_PREFIX=/usr/local/aarch64-freebsd/bin . 721 72220170405: 723 The UDP optimization in entry 20160818 that added the sysctl 724 net.inet.udp.require_l2_bcast has been reverted. L2 broadcast 725 packets will no longer be treated as L3 broadcast packets. 726 72720170331: 728 Binds and sends to the loopback addresses, IPv6 and IPv4, will now 729 use any explicitly assigned loopback address available in the jail 730 instead of using the first assigned address of the jail. 731 73220170329: 733 The ctl.ko module no longer implements the iSCSI target frontend: 734 cfiscsi.ko does instead. 735 736 If building cfiscsi.ko as a kernel module, the module can be loaded 737 via one of the following methods: 738 - `cfiscsi_load="YES"` in loader.conf(5). 739 - Add `cfiscsi` to `$kld_list` in rc.conf(5). 740 - ctladm(8)/ctld(8), when compiled with iSCSI support 741 (`WITH_ISCSI=yes` in src.conf(5)) 742 743 Please see cfiscsi(4) for more details. 744 74520170316: 746 The mmcsd.ko module now additionally depends on geom_flashmap.ko. 747 Also, mmc.ko and mmcsd.ko need to be a matching pair built from the 748 same source (previously, the dependency of mmcsd.ko on mmc.ko was 749 missing, but mmcsd.ko now will refuse to load if it is incompatible 750 with mmc.ko). 751 75220170315: 753 The syntax of ipfw(8) named states was changed to avoid ambiguity. 754 If you have used named states in the firewall rules, you need to modify 755 them after installworld and before rebooting. Now named states must 756 be prefixed with colon. 757 75820170311: 759 The old drm (sys/dev/drm/) drivers for i915 and radeon have been 760 removed as the userland we provide cannot use them. The KMS version 761 (sys/dev/drm2) supports the same hardware. 762 76320170302: 764 Clang, llvm, lldb, compiler-rt and libc++ have been upgraded to 4.0.0. 765 Please see the 20141231 entry below for information about prerequisites 766 and upgrading, if you are not already using clang 3.5.0 or higher. 767 76820170221: 769 The code that provides support for ZFS .zfs/ directory functionality 770 has been reimplemented. It's not possible now to create a snapshot 771 by mkdir under .zfs/snapshot/. That should be the only user visible 772 change. 773 77420170216: 775 EISA bus support has been removed. The WITH_EISA option is no longer 776 valid. 777 77820170215: 779 MCA bus support has been removed. 780 78120170127: 782 The WITH_LLD_AS_LD / WITHOUT_LLD_AS_LD build knobs have been renamed 783 WITH_LLD_IS_LD / WITHOUT_LLD_IS_LD, for consistency with CLANG_IS_CC. 784 78520170112: 786 The EM_MULTIQUEUE kernel configuration option is deprecated now that 787 the em(4) driver conforms to iflib specifications. 788 78920170109: 790 The igb(4), em(4) and lem(4) ethernet drivers are now implemented via 791 IFLIB. If you have a custom kernel configuration that excludes em(4) 792 but you use igb(4), you need to re-add em(4) to your custom configuration. 793 79420161217: 795 Clang, llvm, lldb, compiler-rt and libc++ have been upgraded to 3.9.1. 796 Please see the 20141231 entry below for information about prerequisites 797 and upgrading, if you are not already using clang 3.5.0 or higher. 798 79920161124: 800 Clang, llvm, lldb, compiler-rt and libc++ have been upgraded to 3.9.0. 801 Please see the 20141231 entry below for information about prerequisites 802 and upgrading, if you are not already using clang 3.5.0 or higher. 803 80420161119: 805 The layout of the pmap structure has changed for powerpc to put the pmap 806 statistics at the front for all CPU variations. libkvm(3) and all tools 807 that link against it need to be recompiled. 808 80920161030: 810 isl(4) and cyapa(4) drivers now require a new driver, 811 chromebook_platform(4), to work properly on Chromebook-class hardware. 812 On other types of hardware the drivers may need to be configured using 813 device hints. Please see the corresponding manual pages for details. 814 81520161017: 816 The urtwn(4) driver was merged into rtwn(4) and now consists of 817 rtwn(4) main module + rtwn_usb(4) and rtwn_pci(4) bus-specific 818 parts. 819 Also, firmware for RTL8188CE was renamed due to possible name 820 conflict (rtwnrtl8192cU(B) -> rtwnrtl8192cE(B)) 821 82220161015: 823 GNU rcs has been removed from base. It is available as packages: 824 - rcs: Latest GPLv3 GNU rcs version. 825 - rcs57: Copy of the latest version of GNU rcs (GPLv2) before it was 826 removed from base. 827 82820161008: 829 Use of the cc_cdg, cc_chd, cc_hd, or cc_vegas congestion control 830 modules now requires that the kernel configuration contain the 831 TCP_HHOOK option. (This option is included in the GENERIC kernel.) 832 83320161003: 834 The WITHOUT_ELFCOPY_AS_OBJCOPY src.conf(5) knob has been retired. 835 ELF Tool Chain's elfcopy is always installed as /usr/bin/objcopy. 836 83720160924: 838 Relocatable object files with the extension of .So have been renamed 839 to use an extension of .pico instead. The purpose of this change is 840 to avoid a name clash with shared libraries on case-insensitive file 841 systems. On those file systems, foo.So is the same file as foo.so. 842 84320160918: 844 GNU rcs has been turned off by default. It can (temporarily) be built 845 again by adding WITH_RCS knob in src.conf. 846 Otherwise, GNU rcs is available from packages: 847 - rcs: Latest GPLv3 GNU rcs version. 848 - rcs57: Copy of the latest version of GNU rcs (GPLv2) from base. 849 85020160918: 851 The backup_uses_rcs functionality has been removed from rc.subr. 852 85320160908: 854 The queue(3) debugging macro, QUEUE_MACRO_DEBUG, has been split into 855 two separate components, QUEUE_MACRO_DEBUG_TRACE and 856 QUEUE_MACRO_DEBUG_TRASH. Define both for the original 857 QUEUE_MACRO_DEBUG behavior. 858 85920160824: 860 r304787 changed some ioctl interfaces between the iSCSI userspace 861 programs and the kernel. ctladm, ctld, iscsictl, and iscsid must be 862 rebuilt to work with new kernels. __FreeBSD_version has been bumped 863 to 1200005. 864 86520160818: 866 The UDP receive code has been updated to only treat incoming UDP 867 packets that were addressed to an L2 broadcast address as L3 868 broadcast packets. It is not expected that this will affect any 869 standards-conforming UDP application. The new behaviour can be 870 disabled by setting the sysctl net.inet.udp.require_l2_bcast to 871 0. 872 87320160818: 874 Remove the openbsd_poll system call. 875 __FreeBSD_version has been bumped because of this. 876 87720160708: 878 The stable/11 branch has been created from head@r302406. 879 88020160622: 881 The libc stub for the pipe(2) system call has been replaced with 882 a wrapper that calls the pipe2(2) system call and the pipe(2) 883 system call is now only implemented by the kernels that include 884 "options COMPAT_FREEBSD10" in their config file (this is the 885 default). Users should ensure that this option is enabled in 886 their kernel or upgrade userspace to r302092 before upgrading their 887 kernel. 888 88920160527: 890 CAM will now strip leading spaces from SCSI disks' serial numbers. 891 This will affect users who create UFS filesystems on SCSI disks using 892 those disk's diskid device nodes. For example, if /etc/fstab 893 previously contained a line like 894 "/dev/diskid/DISK-%20%20%20%20%20%20%20ABCDEFG0123456", you should 895 change it to "/dev/diskid/DISK-ABCDEFG0123456". Users of geom 896 transforms like gmirror may also be affected. ZFS users should 897 generally be fine. 898 89920160523: 900 The bitstring(3) API has been updated with new functionality and 901 improved performance. But it is binary-incompatible with the old API. 902 Objects built with the new headers may not be linked against objects 903 built with the old headers. 904 90520160520: 906 The brk and sbrk functions have been removed from libc on arm64. 907 Binutils from ports has been updated to not link to these 908 functions and should be updated to the latest version before 909 installing a new libc. 910 91120160517: 912 The armv6 port now defaults to hard float ABI. Limited support 913 for running both hardfloat and soft float on the same system 914 is available using the libraries installed with -DWITH_LIBSOFT. 915 This has only been tested as an upgrade path for installworld 916 and packages may fail or need manual intervention to run. New 917 packages will be needed. 918 919 To update an existing self-hosted armv6hf system, you must add 920 TARGET_ARCH=armv6 on the make command line for both the build 921 and the install steps. 922 92320160510: 924 Kernel modules compiled outside of a kernel build now default to 925 installing to /boot/modules instead of /boot/kernel. Many kernel 926 modules built this way (such as those in ports) already overrode 927 KMODDIR explicitly to install into /boot/modules. However, 928 manually building and installing a module from /sys/modules will 929 now install to /boot/modules instead of /boot/kernel. 930 93120160414: 932 The CAM I/O scheduler has been committed to the kernel. There should be 933 no user visible impact. This does enable NCQ Trim on ada SSDs. While the 934 list of known rogues that claim support for this but actually corrupt 935 data is believed to be complete, be on the lookout for data 936 corruption. The known rogue list is believed to be complete: 937 938 o Crucial MX100, M550 drives with MU01 firmware. 939 o Micron M510 and M550 drives with MU01 firmware. 940 o Micron M500 prior to MU07 firmware 941 o Samsung 830, 840, and 850 all firmwares 942 o FCCT M500 all firmwares 943 944 Crucial has firmware http://www.crucial.com/usa/en/support-ssd-firmware 945 with working NCQ TRIM. For Micron branded drives, see your sales rep for 946 updated firmware. Black listed drives will work correctly because these 947 drives work correctly so long as no NCQ TRIMs are sent to them. Given 948 this list is the same as found in Linux, it's believed there are no 949 other rogues in the market place. All other models from the above 950 vendors work. 951 952 To be safe, if you are at all concerned, you can quirk each of your 953 drives to prevent NCQ from being sent by setting: 954 kern.cam.ada.X.quirks="0x2" 955 in loader.conf. If the drive requires the 4k sector quirk, set the 956 quirks entry to 0x3. 957 95820160330: 959 The FAST_DEPEND build option has been removed and its functionality is 960 now the one true way. The old mkdep(1) style of 'make depend' has 961 been removed. See 20160311 for further details. 962 96320160317: 964 Resource range types have grown from unsigned long to uintmax_t. All 965 drivers, and anything using libdevinfo, need to be recompiled. 966 96720160311: 968 WITH_FAST_DEPEND is now enabled by default for in-tree and out-of-tree 969 builds. It no longer runs mkdep(1) during 'make depend', and the 970 'make depend' stage can safely be skipped now as it is auto ran 971 when building 'make all' and will generate all SRCS and DPSRCS before 972 building anything else. Dependencies are gathered at compile time with 973 -MF flags kept in separate .depend files per object file. Users should 974 run 'make cleandepend' once if using -DNO_CLEAN to clean out older 975 stale .depend files. 976 97720160306: 978 On amd64, clang 3.8.0 can now insert sections of type AMD64_UNWIND into 979 kernel modules. Therefore, if you load any kernel modules at boot time, 980 please install the boot loaders after you install the kernel, but before 981 rebooting, e.g.: 982 983 make buildworld 984 make buildkernel KERNCONF=YOUR_KERNEL_HERE 985 make installkernel KERNCONF=YOUR_KERNEL_HERE 986 make -C sys/boot install 987 <reboot in single user> 988 989 Then follow the usual steps, described in the General Notes section, 990 below. 991 99220160305: 993 Clang, llvm, lldb and compiler-rt have been upgraded to 3.8.0. Please 994 see the 20141231 entry below for information about prerequisites and 995 upgrading, if you are not already using clang 3.5.0 or higher. 996 99720160301: 998 The AIO subsystem is now a standard part of the kernel. The 999 VFS_AIO kernel option and aio.ko kernel module have been removed. 1000 Due to stability concerns, asynchronous I/O requests are only 1001 permitted on sockets and raw disks by default. To enable 1002 asynchronous I/O requests on all file types, set the 1003 vfs.aio.enable_unsafe sysctl to a non-zero value. 1004 100520160226: 1006 The ELF object manipulation tool objcopy is now provided by the 1007 ELF Tool Chain project rather than by GNU binutils. It should be a 1008 drop-in replacement, with the addition of arm64 support. The 1009 (temporary) src.conf knob WITHOUT_ELFCOPY_AS_OBJCOPY knob may be set 1010 to obtain the GNU version if necessary. 1011 101220160129: 1013 Building ZFS pools on top of zvols is prohibited by default. That 1014 feature has never worked safely; it's always been prone to deadlocks. 1015 Using a zvol as the backing store for a VM guest's virtual disk will 1016 still work, even if the guest is using ZFS. Legacy behavior can be 1017 restored by setting vfs.zfs.vol.recursive=1. 1018 101920160119: 1020 The NONE and HPN patches has been removed from OpenSSH. They are 1021 still available in the security/openssh-portable port. 1022 102320160113: 1024 With the addition of ypldap(8), a new _ypldap user is now required 1025 during installworld. "mergemaster -p" can be used to add the user 1026 prior to installworld, as documented in the handbook. 1027 102820151216: 1029 The tftp loader (pxeboot) now uses the option root-path directive. As a 1030 consequence it no longer looks for a pxeboot.4th file on the tftp 1031 server. Instead it uses the regular /boot infrastructure as with the 1032 other loaders. 1033 103420151211: 1035 The code to start recording plug and play data into the modules has 1036 been committed. While the old tools will properly build a new kernel, 1037 a number of warnings about "unknown metadata record 4" will be produced 1038 for an older kldxref. To avoid such warnings, make sure to rebuild 1039 the kernel toolchain (or world). Make sure that you have r292078 or 1040 later when trying to build 292077 or later before rebuilding. 1041 104220151207: 1043 Debug data files are now built by default with 'make buildworld' and 1044 installed with 'make installworld'. This facilitates debugging but 1045 requires more disk space both during the build and for the installed 1046 world. Debug files may be disabled by setting WITHOUT_DEBUG_FILES=yes 1047 in src.conf(5). 1048 104920151130: 1050 r291527 changed the internal interface between the nfsd.ko and 1051 nfscommon.ko modules. As such, they must both be upgraded to-gether. 1052 __FreeBSD_version has been bumped because of this. 1053 105420151108: 1055 Add support for unicode collation strings leads to a change of 1056 order of files listed by ls(1) for example. To get back to the old 1057 behaviour, set LC_COLLATE environment variable to "C". 1058 1059 Databases administrators will need to reindex their databases given 1060 collation results will be different. 1061 1062 Due to a bug in install(1) it is recommended to remove the ancient 1063 locales before running make installworld. 1064 1065 rm -rf /usr/share/locale/* 1066 106720151030: 1068 The OpenSSL has been upgraded to 1.0.2d. Any binaries requiring 1069 libcrypto.so.7 or libssl.so.7 must be recompiled. 1070 107120151020: 1072 Qlogic 24xx/25xx firmware images were updated from 5.5.0 to 7.3.0. 1073 Kernel modules isp_2400_multi and isp_2500_multi were removed and 1074 should be replaced with isp_2400 and isp_2500 modules respectively. 1075 107620151017: 1077 The build previously allowed using 'make -n' to not recurse into 1078 sub-directories while showing what commands would be executed, and 1079 'make -n -n' to recursively show commands. Now 'make -n' will recurse 1080 and 'make -N' will not. 1081 108220151012: 1083 If you specify SENDMAIL_MC or SENDMAIL_CF in make.conf, mergemaster 1084 and etcupdate will now use this file. A custom sendmail.cf is now 1085 updated via this mechanism rather than via installworld. If you had 1086 excluded sendmail.cf in mergemaster.rc or etcupdate.conf, you may 1087 want to remove the exclusion or change it to "always install". 1088 /etc/mail/sendmail.cf is now managed the same way regardless of 1089 whether SENDMAIL_MC/SENDMAIL_CF is used. If you are not using 1090 SENDMAIL_MC/SENDMAIL_CF there should be no change in behavior. 1091 109220151011: 1093 Compatibility shims for legacy ATA device names have been removed. 1094 It includes ATA_STATIC_ID kernel option, kern.cam.ada.legacy_aliases 1095 and kern.geom.raid.legacy_aliases loader tunables, kern.devalias.* 1096 environment variables, /dev/ad* and /dev/ar* symbolic links. 1097 109820151006: 1099 Clang, llvm, lldb, compiler-rt and libc++ have been upgraded to 3.7.0. 1100 Please see the 20141231 entry below for information about prerequisites 1101 and upgrading, if you are not already using clang 3.5.0 or higher. 1102 110320150924: 1104 Kernel debug files have been moved to /usr/lib/debug/boot/kernel/, 1105 and renamed from .symbols to .debug. This reduces the size requirements 1106 on the boot partition or file system and provides consistency with 1107 userland debug files. 1108 1109 When using the supported kernel installation method the 1110 /usr/lib/debug/boot/kernel directory will be renamed (to kernel.old) 1111 as is done with /boot/kernel. 1112 1113 Developers wishing to maintain the historical behavior of installing 1114 debug files in /boot/kernel/ can set KERN_DEBUGDIR="" in src.conf(5). 1115 111620150827: 1117 The wireless drivers had undergone changes that remove the 'parent 1118 interface' from the ifconfig -l output. The rc.d network scripts 1119 used to check presence of a parent interface in the list, so old 1120 scripts would fail to start wireless networking. Thus, etcupdate(3) 1121 or mergemaster(8) run is required after kernel update, to update your 1122 rc.d scripts in /etc. 1123 112420150827: 1125 pf no longer supports 'scrub fragment crop' or 'scrub fragment drop-ovl' 1126 These configurations are now automatically interpreted as 1127 'scrub fragment reassemble'. 1128 112920150817: 1130 Kernel-loadable modules for the random(4) device are back. To use 1131 them, the kernel must have 1132 1133 device random 1134 options RANDOM_LOADABLE 1135 1136 kldload(8) can then be used to load random_fortuna.ko 1137 or random_yarrow.ko. Please note that due to the indirect 1138 function calls that the loadable modules need to provide, 1139 the build-in variants will be slightly more efficient. 1140 1141 The random(4) kernel option RANDOM_DUMMY has been retired due to 1142 unpopularity. It was not all that useful anyway. 1143 114420150813: 1145 The WITHOUT_ELFTOOLCHAIN_TOOLS src.conf(5) knob has been retired. 1146 Control over building the ELF Tool Chain tools is now provided by 1147 the WITHOUT_TOOLCHAIN knob. 1148 114920150810: 1150 The polarity of Pulse Per Second (PPS) capture events with the 1151 uart(4) driver has been corrected. Prior to this change the PPS 1152 "assert" event corresponded to the trailing edge of a positive PPS 1153 pulse and the "clear" event was the leading edge of the next pulse. 1154 1155 As the width of a PPS pulse in a typical GPS receiver is on the 1156 order of 1 millisecond, most users will not notice any significant 1157 difference with this change. 1158 1159 Anyone who has compensated for the historical polarity reversal by 1160 configuring a negative offset equal to the pulse width will need to 1161 remove that workaround. 1162 116320150809: 1164 The default group assigned to /dev/dri entries has been changed 1165 from 'wheel' to 'video' with the id of '44'. If you want to have 1166 access to the dri devices please add yourself to the video group 1167 with: 1168 1169 # pw groupmod video -m $USER 1170 117120150806: 1172 The menu.rc and loader.rc files will now be replaced during 1173 upgrades. Please migrate local changes to menu.rc.local and 1174 loader.rc.local instead. 1175 117620150805: 1177 GNU Binutils versions of addr2line, c++filt, nm, readelf, size, 1178 strings and strip have been removed. The src.conf(5) knob 1179 WITHOUT_ELFTOOLCHAIN_TOOLS no longer provides the binutils tools. 1180 118120150728: 1182 As ZFS requires more kernel stack pages than is the default on some 1183 architectures e.g. i386, it now warns if KSTACK_PAGES is less than 1184 ZFS_MIN_KSTACK_PAGES (which is 4 at the time of writing). 1185 1186 Please consider using 'options KSTACK_PAGES=X' where X is greater 1187 than or equal to ZFS_MIN_KSTACK_PAGES i.e. 4 in such configurations. 1188 118920150706: 1190 sendmail has been updated to 8.15.2. Starting with FreeBSD 11.0 1191 and sendmail 8.15, sendmail uses uncompressed IPv6 addresses by 1192 default, i.e., they will not contain "::". For example, instead 1193 of ::1, it will be 0:0:0:0:0:0:0:1. This permits a zero subnet 1194 to have a more specific match, such as different map entries for 1195 IPv6:0:0 vs IPv6:0. This change requires that configuration 1196 data (including maps, files, classes, custom ruleset, etc.) must 1197 use the same format, so make certain such configuration data is 1198 upgrading. As a very simple check search for patterns like 1199 'IPv6:[0-9a-fA-F:]*::' and 'IPv6::'. To return to the old 1200 behavior, set the m4 option confUSE_COMPRESSED_IPV6_ADDRESSES or 1201 the cf option UseCompressedIPv6Addresses. 1202 120320150630: 1204 The default kernel entropy-processing algorithm is now 1205 Fortuna, replacing Yarrow. 1206 1207 Assuming you have 'device random' in your kernel config 1208 file, the configurations allow a kernel option to override 1209 this default. You may choose *ONE* of: 1210 1211 options RANDOM_YARROW # Legacy /dev/random algorithm. 1212 options RANDOM_DUMMY # Blocking-only driver. 1213 1214 If you have neither, you get Fortuna. For most people, 1215 read no further, Fortuna will give a /dev/random that works 1216 like it always used to, and the difference will be irrelevant. 1217 1218 If you remove 'device random', you get *NO* kernel-processed 1219 entropy at all. This may be acceptable to folks building 1220 embedded systems, but has complications. Carry on reading, 1221 and it is assumed you know what you need. 1222 1223 *PLEASE* read random(4) and random(9) if you are in the 1224 habit of tweaking kernel configs, and/or if you are a member 1225 of the embedded community, wanting specific and not-usual 1226 behaviour from your security subsystems. 1227 1228 NOTE!! If you use RANDOM_DUMMY and/or have no 'device 1229 random', you will NOT have a functioning /dev/random, and 1230 many cryptographic features will not work, including SSH. 1231 You may also find strange behaviour from the random(3) set 1232 of library functions, in particular sranddev(3), srandomdev(3) 1233 and arc4random(3). The reason for this is that the KERN_ARND 1234 sysctl only returns entropy if it thinks it has some to 1235 share, and with RANDOM_DUMMY or no 'device random' this 1236 will never happen. 1237 123820150623: 1239 An additional fix for the issue described in the 20150614 sendmail 1240 entry below has been committed in revision 284717. 1241 124220150616: 1243 FreeBSD's old make (fmake) has been removed from the system. It is 1244 available as the devel/fmake port or via pkg install fmake. 1245 124620150615: 1247 The fix for the issue described in the 20150614 sendmail entry 1248 below has been committed in revision 284436. The work 1249 around described in that entry is no longer needed unless the 1250 default setting is overridden by a confDH_PARAMETERS configuration 1251 setting of '5' or pointing to a 512 bit DH parameter file. 1252 125320150614: 1254 ALLOW_DEPRECATED_ATF_TOOLS/ATFFILE support has been removed from 1255 atf.test.mk (included from bsd.test.mk). Please upgrade devel/atf 1256 and devel/kyua to version 0.20+ and adjust any calling code to work 1257 with Kyuafile and kyua. 1258 125920150614: 1260 The import of openssl to address the FreeBSD-SA-15:10.openssl 1261 security advisory includes a change which rejects handshakes 1262 with DH parameters below 768 bits. sendmail releases prior 1263 to 8.15.2 (not yet released), defaulted to a 512 bit 1264 DH parameter setting for client connections. To work around 1265 this interoperability, sendmail can be configured to use a 1266 2048 bit DH parameter by: 1267 1268 1. Edit /etc/mail/`hostname`.mc 1269 2. If a setting for confDH_PARAMETERS does not exist or 1270 exists and is set to a string beginning with '5', 1271 replace it with '2'. 1272 3. If a setting for confDH_PARAMETERS exists and is set to 1273 a file path, create a new file with: 1274 openssl dhparam -out /path/to/file 2048 1275 4. Rebuild the .cf file: 1276 cd /etc/mail/; make; make install 1277 5. Restart sendmail: 1278 cd /etc/mail/; make restart 1279 1280 A sendmail patch is coming, at which time this file will be 1281 updated. 1282 128320150604: 1284 Generation of legacy formatted entries have been disabled by default 1285 in pwd_mkdb(8), as all base system consumers of the legacy formatted 1286 entries were converted to use the new format by default when the new, 1287 machine independent format have been added and supported since FreeBSD 1288 5.x. 1289 1290 Please see the pwd_mkdb(8) manual page for further details. 1291 129220150525: 1293 Clang and llvm have been upgraded to 3.6.1 release. Please see the 1294 20141231 entry below for information about prerequisites and upgrading, 1295 if you are not already using 3.5.0 or higher. 1296 129720150521: 1298 TI platform code switched to using vendor DTS files and this update 1299 may break existing systems running on Beaglebone, Beaglebone Black, 1300 and Pandaboard: 1301 1302 - dtb files should be regenerated/reinstalled. Filenames are the 1303 same but content is different now 1304 - GPIO addressing was changed, now each GPIO bank (32 pins per bank) 1305 has its own /dev/gpiocX device, e.g. pin 121 on /dev/gpioc0 in old 1306 addressing scheme is now pin 25 on /dev/gpioc3. 1307 - Pandaboard: /etc/ttys should be updated, serial console device is 1308 now /dev/ttyu2, not /dev/ttyu0 1309 131020150501: 1311 soelim(1) from gnu/usr.bin/groff has been replaced by usr.bin/soelim. 1312 If you need the GNU extension from groff soelim(1), install groff 1313 from package: pkg install groff, or via ports: textproc/groff. 1314 131520150423: 1316 chmod, chflags, chown and chgrp now affect symlinks in -R mode as 1317 defined in symlink(7); previously symlinks were silently ignored. 1318 131920150415: 1320 The const qualifier has been removed from iconv(3) to comply with 1321 POSIX. The ports tree is aware of this from r384038 onwards. 1322 132320150416: 1324 Libraries specified by LIBADD in Makefiles must have a corresponding 1325 DPADD_<lib> variable to ensure correct dependencies. This is now 1326 enforced in src.libnames.mk. 1327 132820150324: 1329 From legacy ata(4) driver was removed support for SATA controllers 1330 supported by more functional drivers ahci(4), siis(4) and mvs(4). 1331 Kernel modules ataahci and ataadaptec were removed completely, 1332 replaced by ahci and mvs modules respectively. 1333 133420150315: 1335 Clang, llvm and lldb have been upgraded to 3.6.0 release. Please see 1336 the 20141231 entry below for information about prerequisites and 1337 upgrading, if you are not already using 3.5.0 or higher. 1338 133920150307: 1340 The 32-bit PowerPC kernel has been changed to a position-independent 1341 executable. This can only be booted with a version of loader(8) 1342 newer than January 31, 2015, so make sure to update both world and 1343 kernel before rebooting. 1344 134520150217: 1346 If you are running a -CURRENT kernel since r273872 (Oct 30th, 2014), 1347 but before r278950, the RNG was not seeded properly. Immediately 1348 upgrade the kernel to r278950 or later and regenerate any keys (e.g. 1349 ssh keys or openssl keys) that were generated w/ a kernel from that 1350 range. This does not affect programs that directly used /dev/random 1351 or /dev/urandom. All userland uses of arc4random(3) are affected. 1352 135320150210: 1354 The autofs(4) ABI was changed in order to restore binary compatibility 1355 with 10.1-RELEASE. The automountd(8) daemon needs to be rebuilt to work 1356 with the new kernel. 1357 135820150131: 1359 The powerpc64 kernel has been changed to a position-independent 1360 executable. This can only be booted with a new version of loader(8), 1361 so make sure to update both world and kernel before rebooting. 1362 136320150118: 1364 Clang and llvm have been upgraded to 3.5.1 release. This is a bugfix 1365 only release, no new features have been added. Please see the 20141231 1366 entry below for information about prerequisites and upgrading, if you 1367 are not already using 3.5.0. 1368 136920150107: 1370 ELF tools addr2line, elfcopy (strip), nm, size, and strings are now 1371 taken from the ELF Tool Chain project rather than GNU binutils. They 1372 should be drop-in replacements, with the addition of arm64 support. 1373 The WITHOUT_ELFTOOLCHAIN_TOOLS= knob may be used to obtain the 1374 binutils tools, if necessary. See 20150805 for updated information. 1375 137620150105: 1377 The default Unbound configuration now enables remote control 1378 using a local socket. Users who have already enabled the 1379 local_unbound service should regenerate their configuration 1380 by running "service local_unbound setup" as root. 1381 138220150102: 1383 The GNU texinfo and GNU info pages have been removed. 1384 To be able to view GNU info pages please install texinfo from ports. 1385 138620141231: 1387 Clang, llvm and lldb have been upgraded to 3.5.0 release. 1388 1389 As of this release, a prerequisite for building clang, llvm and lldb is 1390 a C++11 capable compiler and C++11 standard library. This means that to 1391 be able to successfully build the cross-tools stage of buildworld, with 1392 clang as the bootstrap compiler, your system compiler or cross compiler 1393 should either be clang 3.3 or later, or gcc 4.8 or later, and your 1394 system C++ library should be libc++, or libdstdc++ from gcc 4.8 or 1395 later. 1396 1397 On any standard FreeBSD 10.x or 11.x installation, where clang and 1398 libc++ are on by default (that is, on x86 or arm), this should work out 1399 of the box. 1400 1401 On 9.x installations where clang is enabled by default, e.g. on x86 and 1402 powerpc, libc++ will not be enabled by default, so libc++ should be 1403 built (with clang) and installed first. If both clang and libc++ are 1404 missing, build clang first, then use it to build libc++. 1405 1406 On 8.x and earlier installations, upgrade to 9.x first, and then follow 1407 the instructions for 9.x above. 1408 1409 Sparc64 and mips users are unaffected, as they still use gcc 4.2.1 by 1410 default, and do not build clang. 1411 1412 Many embedded systems are resource constrained, and will not be able to 1413 build clang in a reasonable time, or in some cases at all. In those 1414 cases, cross building bootable systems on amd64 is a workaround. 1415 1416 This new version of clang introduces a number of new warnings, of which 1417 the following are most likely to appear: 1418 1419 -Wabsolute-value 1420 1421 This warns in two cases, for both C and C++: 1422 * When the code is trying to take the absolute value of an unsigned 1423 quantity, which is effectively a no-op, and almost never what was 1424 intended. The code should be fixed, if at all possible. If you are 1425 sure that the unsigned quantity can be safely cast to signed, without 1426 loss of information or undefined behavior, you can add an explicit 1427 cast, or disable the warning. 1428 1429 * When the code is trying to take an absolute value, but the called 1430 abs() variant is for the wrong type, which can lead to truncation. 1431 If you want to disable the warning instead of fixing the code, please 1432 make sure that truncation will not occur, or it might lead to unwanted 1433 side-effects. 1434 1435 -Wtautological-undefined-compare and 1436 -Wundefined-bool-conversion 1437 1438 These warn when C++ code is trying to compare 'this' against NULL, while 1439 'this' should never be NULL in well-defined C++ code. However, there is 1440 some legacy (pre C++11) code out there, which actively abuses this 1441 feature, which was less strictly defined in previous C++ versions. 1442 1443 Squid and openjdk do this, for example. The warning can be turned off 1444 for C++98 and earlier, but compiling the code in C++11 mode might result 1445 in unexpected behavior; for example, the parts of the program that are 1446 unreachable could be optimized away. 1447 144820141222: 1449 The old NFS client and server (kernel options NFSCLIENT, NFSSERVER) 1450 kernel sources have been removed. The .h files remain, since some 1451 utilities include them. This will need to be fixed later. 1452 If "mount -t oldnfs ..." is attempted, it will fail. 1453 If the "-o" option on mountd(8), nfsd(8) or nfsstat(1) is used, 1454 the utilities will report errors. 1455 145620141121: 1457 The handling of LOCAL_LIB_DIRS has been altered to skip addition of 1458 directories to top level SUBDIR variable when their parent 1459 directory is included in LOCAL_DIRS. Users with build systems with 1460 such hierarchies and without SUBDIR entries in the parent 1461 directory Makefiles should add them or add the directories to 1462 LOCAL_DIRS. 1463 146420141109: 1465 faith(4) and faithd(8) have been removed from the base system. Faith 1466 has been obsolete for a very long time. 1467 146820141104: 1469 vt(4), the new console driver, is enabled by default. It brings 1470 support for Unicode and double-width characters, as well as 1471 support for UEFI and integration with the KMS kernel video 1472 drivers. 1473 1474 You may need to update your console settings in /etc/rc.conf, 1475 most probably the keymap. During boot, /etc/rc.d/syscons will 1476 indicate what you need to do. 1477 1478 vt(4) still has issues and lacks some features compared to 1479 syscons(4). See the wiki for up-to-date information: 1480 https://wiki.freebsd.org/Newcons 1481 1482 If you want to keep using syscons(4), you can do so by adding 1483 the following line to /boot/loader.conf: 1484 kern.vty=sc 1485 148620141102: 1487 pjdfstest has been integrated into kyua as an opt-in test suite. 1488 Please see share/doc/pjdfstest/README for more details on how to 1489 execute it. 1490 149120141009: 1492 gperf has been removed from the base system for architectures 1493 that use clang. Ports that require gperf will obtain it from the 1494 devel/gperf port. 1495 149620140923: 1497 pjdfstest has been moved from tools/regression/pjdfstest to 1498 contrib/pjdfstest . 1499 150020140922: 1501 At svn r271982, The default linux compat kernel ABI has been adjusted 1502 to 2.6.18 in support of the linux-c6 compat ports infrastructure 1503 update. If you wish to continue using the linux-f10 compat ports, 1504 add compat.linux.osrelease=2.6.16 to your local sysctl.conf. Users are 1505 encouraged to update their linux-compat packages to linux-c6 during 1506 their next update cycle. 1507 150820140729: 1509 The ofwfb driver, used to provide a graphics console on PowerPC when 1510 using vt(4), no longer allows mmap() of all physical memory. This 1511 will prevent Xorg on PowerPC with some ATI graphics cards from 1512 initializing properly unless x11-servers/xorg-server is updated to 1513 1.12.4_8 or newer. 1514 151520140723: 1516 The xdev targets have been converted to using TARGET and 1517 TARGET_ARCH instead of XDEV and XDEV_ARCH. 1518 151920140719: 1520 The default unbound configuration has been modified to address 1521 issues with reverse lookups on networks that use private 1522 address ranges. If you use the local_unbound service, run 1523 "service local_unbound setup" as root to regenerate your 1524 configuration, then "service local_unbound reload" to load the 1525 new configuration. 1526 152720140709: 1528 The GNU texinfo and GNU info pages are not built and installed 1529 anymore, WITH_INFO knob has been added to allow to built and install 1530 them again. 1531 UPDATE: see 20150102 entry on texinfo's removal 1532 153320140708: 1534 The GNU readline library is now an INTERNALLIB - that is, it is 1535 statically linked into consumers (GDB and variants) in the base 1536 system, and the shared library is no longer installed. The 1537 devel/readline port is available for third party software that 1538 requires readline. 1539 154020140702: 1541 The Itanium architecture (ia64) has been removed from the list of 1542 known architectures. This is the first step in the removal of the 1543 architecture. 1544 154520140701: 1546 Commit r268115 has added NFSv4.1 server support, merged from 1547 projects/nfsv4.1-server. Since this includes changes to the 1548 internal interfaces between the NFS related modules, a full 1549 build of the kernel and modules will be necessary. 1550 __FreeBSD_version has been bumped. 1551 155220140629: 1553 The WITHOUT_VT_SUPPORT kernel config knob has been renamed 1554 WITHOUT_VT. (The other _SUPPORT knobs have a consistent meaning 1555 which differs from the behaviour controlled by this knob.) 1556 155720140619: 1558 Maximal length of the serial number in CTL was increased from 16 to 1559 64 chars, that breaks ABI. All CTL-related tools, such as ctladm 1560 and ctld, need to be rebuilt to work with a new kernel. 1561 156220140606: 1563 The libatf-c and libatf-c++ major versions were downgraded to 0 and 1564 1 respectively to match the upstream numbers. They were out of 1565 sync because, when they were originally added to FreeBSD, the 1566 upstream versions were not respected. These libraries are private 1567 and not yet built by default, so renumbering them should be a 1568 non-issue. However, unclean source trees will yield broken test 1569 programs once the operator executes "make delete-old-libs" after a 1570 "make installworld". 1571 1572 Additionally, the atf-sh binary was made private by moving it into 1573 /usr/libexec/. Already-built shell test programs will keep the 1574 path to the old binary so they will break after "make delete-old" 1575 is run. 1576 1577 If you are using WITH_TESTS=yes (not the default), wipe the object 1578 tree and rebuild from scratch to prevent spurious test failures. 1579 This is only needed once: the misnumbered libraries and misplaced 1580 binaries have been added to OptionalObsoleteFiles.inc so they will 1581 be removed during a clean upgrade. 1582 158320140512: 1584 Clang and llvm have been upgraded to 3.4.1 release. 1585 158620140508: 1587 We bogusly installed src.opts.mk in /usr/share/mk. This file should 1588 be removed to avoid issues in the future (and has been added to 1589 ObsoleteFiles.inc). 1590 159120140505: 1592 /etc/src.conf now affects only builds of the FreeBSD src tree. In the 1593 past, it affected all builds that used the bsd.*.mk files. The old 1594 behavior was a bug, but people may have relied upon it. To get this 1595 behavior back, you can .include /etc/src.conf from /etc/make.conf 1596 (which is still global and isn't changed). This also changes the 1597 behavior of incremental builds inside the tree of individual 1598 directories. Set MAKESYSPATH to ".../share/mk" to do that. 1599 Although this has survived make universe and some upgrade scenarios, 1600 other upgrade scenarios may have broken. At least one form of 1601 temporary breakage was fixed with MAKESYSPATH settings for buildworld 1602 as well... In cases where MAKESYSPATH isn't working with this 1603 setting, you'll need to set it to the full path to your tree. 1604 1605 One side effect of all this cleaning up is that bsd.compiler.mk 1606 is no longer implicitly included by bsd.own.mk. If you wish to 1607 use COMPILER_TYPE, you must now explicitly include bsd.compiler.mk 1608 as well. 1609 161020140430: 1611 The lindev device has been removed since /dev/full has been made a 1612 standard device. __FreeBSD_version has been bumped. 1613 161420140424: 1615 The knob WITHOUT_VI was added to the base system, which controls 1616 building ex(1), vi(1), etc. Older releases of FreeBSD required ex(1) 1617 in order to reorder files share/termcap and didn't build ex(1) as a 1618 build tool, so building/installing with WITH_VI is highly advised for 1619 build hosts for older releases. 1620 1621 This issue has been fixed in stable/9 and stable/10 in r277022 and 1622 r276991, respectively. 1623 162420140418: 1625 The YES_HESIOD knob has been removed. It has been obsolete for 1626 a decade. Please move to using WITH_HESIOD instead or your builds 1627 will silently lack HESIOD. 1628 162920140405: 1630 The uart(4) driver has been changed with respect to its handling 1631 of the low-level console. Previously the uart(4) driver prevented 1632 any process from changing the baudrate or the CLOCAL and HUPCL 1633 control flags. By removing the restrictions, operators can make 1634 changes to the serial console port without having to reboot. 1635 However, when getty(8) is started on the serial device that is 1636 associated with the low-level console, a misconfigured terminal 1637 line in /etc/ttys will now have a real impact. 1638 Before upgrading the kernel, make sure that /etc/ttys has the 1639 serial console device configured as 3wire without baudrate to 1640 preserve the previous behaviour. E.g: 1641 ttyu0 "/usr/libexec/getty 3wire" vt100 on secure 1642 164320140306: 1644 Support for libwrap (TCP wrappers) in rpcbind was disabled by default 1645 to improve performance. To re-enable it, if needed, run rpcbind 1646 with command line option -W. 1647 164820140226: 1649 Switched back to the GPL dtc compiler due to updates in the upstream 1650 dts files not being supported by the BSDL dtc compiler. You will need 1651 to rebuild your kernel toolchain to pick up the new compiler. Core dumps 1652 may result while building dtb files during a kernel build if you fail 1653 to do so. Set WITHOUT_GPL_DTC if you require the BSDL compiler. 1654 165520140216: 1656 Clang and llvm have been upgraded to 3.4 release. 1657 165820140216: 1659 The nve(4) driver has been removed. Please use the nfe(4) driver 1660 for NVIDIA nForce MCP Ethernet adapters instead. 1661 166220140212: 1663 An ABI incompatibility crept into the libc++ 3.4 import in r261283. 1664 This could cause certain C++ applications using shared libraries built 1665 against the previous version of libc++ to crash. The incompatibility 1666 has now been fixed, but any C++ applications or shared libraries built 1667 between r261283 and r261801 should be recompiled. 1668 166920140204: 1670 OpenSSH will now ignore errors caused by kernel lacking of Capsicum 1671 capability mode support. Please note that enabling the feature in 1672 kernel is still highly recommended. 1673 167420140131: 1675 OpenSSH is now built with sandbox support, and will use sandbox as 1676 the default privilege separation method. This requires Capsicum 1677 capability mode support in kernel. 1678 167920140128: 1680 The libelf and libdwarf libraries have been updated to newer 1681 versions from upstream. Shared library version numbers for 1682 these two libraries were bumped. Any ports or binaries 1683 requiring these two libraries should be recompiled. 1684 __FreeBSD_version is bumped to 1100006. 1685 168620140110: 1687 If a Makefile in a tests/ directory was auto-generating a Kyuafile 1688 instead of providing an explicit one, this would prevent such 1689 Makefile from providing its own Kyuafile in the future during 1690 NO_CLEAN builds. This has been fixed in the Makefiles but manual 1691 intervention is needed to clean an objdir if you use NO_CLEAN: 1692 # find /usr/obj -name Kyuafile | xargs rm -f 1693 169420131213: 1695 The behavior of gss_pseudo_random() for the krb5 mechanism 1696 has changed, for applications requesting a longer random string 1697 than produced by the underlying enctype's pseudo-random() function. 1698 In particular, the random string produced from a session key of 1699 enctype aes256-cts-hmac-sha1-96 or aes256-cts-hmac-sha1-96 will 1700 be different at the 17th octet and later, after this change. 1701 The counter used in the PRF+ construction is now encoded as a 1702 big-endian integer in accordance with RFC 4402. 1703 __FreeBSD_version is bumped to 1100004. 1704 170520131108: 1706 The WITHOUT_ATF build knob has been removed and its functionality 1707 has been subsumed into the more generic WITHOUT_TESTS. If you were 1708 using the former to disable the build of the ATF libraries, you 1709 should change your settings to use the latter. 1710 171120131025: 1712 The default version of mtree is nmtree which is obtained from 1713 NetBSD. The output is generally the same, but may vary 1714 slightly. If you found you need identical output adding 1715 "-F freebsd9" to the command line should do the trick. For the 1716 time being, the old mtree is available as fmtree. 1717 171820131014: 1719 libbsdyml has been renamed to libyaml and moved to /usr/lib/private. 1720 This will break ports-mgmt/pkg. Rebuild the port, or upgrade to pkg 1721 1.1.4_8 and verify bsdyml not linked in, before running "make 1722 delete-old-libs": 1723 # make -C /usr/ports/ports-mgmt/pkg build deinstall install clean 1724 or 1725 # pkg install pkg; ldd /usr/local/sbin/pkg | grep bsdyml 1726 172720131010: 1728 The stable/10 branch has been created in subversion from head 1729 revision r256279. 1730 1731COMMON ITEMS: 1732 1733 General Notes 1734 ------------- 1735 Avoid using make -j when upgrading. While generally safe, there are 1736 sometimes problems using -j to upgrade. If your upgrade fails with 1737 -j, please try again without -j. From time to time in the past there 1738 have been problems using -j with buildworld and/or installworld. This 1739 is especially true when upgrading between "distant" versions (eg one 1740 that cross a major release boundary or several minor releases, or when 1741 several months have passed on the -current branch). 1742 1743 Sometimes, obscure build problems are the result of environment 1744 poisoning. This can happen because the make utility reads its 1745 environment when searching for values for global variables. To run 1746 your build attempts in an "environmental clean room", prefix all make 1747 commands with 'env -i '. See the env(1) manual page for more details. 1748 1749 When upgrading from one major version to another it is generally best to 1750 upgrade to the latest code in the currently installed branch first, then 1751 do an upgrade to the new branch. This is the best-tested upgrade path, 1752 and has the highest probability of being successful. Please try this 1753 approach if you encounter problems with a major version upgrade. Since 1754 the stable 4.x branch point, one has generally been able to upgrade from 1755 anywhere in the most recent stable branch to head / current (or even the 1756 last couple of stable branches). See the top of this file when there's 1757 an exception. 1758 1759 When upgrading a live system, having a root shell around before 1760 installing anything can help undo problems. Not having a root shell 1761 around can lead to problems if pam has changed too much from your 1762 starting point to allow continued authentication after the upgrade. 1763 1764 This file should be read as a log of events. When a later event changes 1765 information of a prior event, the prior event should not be deleted. 1766 Instead, a pointer to the entry with the new information should be 1767 placed in the old entry. Readers of this file should also sanity check 1768 older entries before relying on them blindly. Authors of new entries 1769 should write them with this in mind. 1770 1771 ZFS notes 1772 --------- 1773 When upgrading the boot ZFS pool to a new version, always follow 1774 these two steps: 1775 1776 1.) recompile and reinstall the ZFS boot loader and boot block 1777 (this is part of "make buildworld" and "make installworld") 1778 1779 2.) update the ZFS boot block on your boot drive 1780 1781 The following example updates the ZFS boot block on the first 1782 partition (freebsd-boot) of a GPT partitioned drive ada0: 1783 "gpart bootcode -p /boot/gptzfsboot -i 1 ada0" 1784 1785 Non-boot pools do not need these updates. 1786 1787 To build a kernel 1788 ----------------- 1789 If you are updating from a prior version of FreeBSD (even one just 1790 a few days old), you should follow this procedure. It is the most 1791 failsafe as it uses a /usr/obj tree with a fresh mini-buildworld, 1792 1793 make kernel-toolchain 1794 make -DALWAYS_CHECK_MAKE buildkernel KERNCONF=YOUR_KERNEL_HERE 1795 make -DALWAYS_CHECK_MAKE installkernel KERNCONF=YOUR_KERNEL_HERE 1796 1797 To test a kernel once 1798 --------------------- 1799 If you just want to boot a kernel once (because you are not sure 1800 if it works, or if you want to boot a known bad kernel to provide 1801 debugging information) run 1802 make installkernel KERNCONF=YOUR_KERNEL_HERE KODIR=/boot/testkernel 1803 nextboot -k testkernel 1804 1805 To rebuild everything and install it on the current system. 1806 ----------------------------------------------------------- 1807 # Note: sometimes if you are running current you gotta do more than 1808 # is listed here if you are upgrading from a really old current. 1809 1810 <make sure you have good level 0 dumps> 1811 make buildworld 1812 make buildkernel KERNCONF=YOUR_KERNEL_HERE 1813 make installkernel KERNCONF=YOUR_KERNEL_HERE 1814 [1] 1815 <reboot in single user> [3] 1816 mergemaster -Fp [5] 1817 make installworld 1818 mergemaster -Fi [4] 1819 make delete-old [6] 1820 <reboot> 1821 1822 To cross-install current onto a separate partition 1823 -------------------------------------------------- 1824 # In this approach we use a separate partition to hold 1825 # current's root, 'usr', and 'var' directories. A partition 1826 # holding "/", "/usr" and "/var" should be about 2GB in 1827 # size. 1828 1829 <make sure you have good level 0 dumps> 1830 <boot into -stable> 1831 make buildworld 1832 make buildkernel KERNCONF=YOUR_KERNEL_HERE 1833 <maybe newfs current's root partition> 1834 <mount current's root partition on directory ${CURRENT_ROOT}> 1835 make installworld DESTDIR=${CURRENT_ROOT} -DDB_FROM_SRC 1836 make distribution DESTDIR=${CURRENT_ROOT} # if newfs'd 1837 make installkernel KERNCONF=YOUR_KERNEL_HERE DESTDIR=${CURRENT_ROOT} 1838 cp /etc/fstab ${CURRENT_ROOT}/etc/fstab # if newfs'd 1839 <edit ${CURRENT_ROOT}/etc/fstab to mount "/" from the correct partition> 1840 <reboot into current> 1841 <do a "native" rebuild/install as described in the previous section> 1842 <maybe install compatibility libraries from ports/misc/compat*> 1843 <reboot> 1844 1845 1846 To upgrade in-place from stable to current 1847 ---------------------------------------------- 1848 <make sure you have good level 0 dumps> 1849 make buildworld [9] 1850 make buildkernel KERNCONF=YOUR_KERNEL_HERE [8] 1851 make installkernel KERNCONF=YOUR_KERNEL_HERE 1852 [1] 1853 <reboot in single user> [3] 1854 mergemaster -Fp [5] 1855 make installworld 1856 mergemaster -Fi [4] 1857 make delete-old [6] 1858 <reboot> 1859 1860 Make sure that you've read the UPDATING file to understand the 1861 tweaks to various things you need. At this point in the life 1862 cycle of current, things change often and you are on your own 1863 to cope. The defaults can also change, so please read ALL of 1864 the UPDATING entries. 1865 1866 Also, if you are tracking -current, you must be subscribed to 1867 freebsd-current@freebsd.org. Make sure that before you update 1868 your sources that you have read and understood all the recent 1869 messages there. If in doubt, please track -stable which has 1870 much fewer pitfalls. 1871 1872 [1] If you have third party modules, such as vmware, you 1873 should disable them at this point so they don't crash your 1874 system on reboot. 1875 1876 [3] From the bootblocks, boot -s, and then do 1877 fsck -p 1878 mount -u / 1879 mount -a 1880 cd src 1881 adjkerntz -i # if CMOS is wall time 1882 Also, when doing a major release upgrade, it is required that 1883 you boot into single user mode to do the installworld. 1884 1885 [4] Note: This step is non-optional. Failure to do this step 1886 can result in a significant reduction in the functionality of the 1887 system. Attempting to do it by hand is not recommended and those 1888 that pursue this avenue should read this file carefully, as well 1889 as the archives of freebsd-current and freebsd-hackers mailing lists 1890 for potential gotchas. The -U option is also useful to consider. 1891 See mergemaster(8) for more information. 1892 1893 [5] Usually this step is a no-op. However, from time to time 1894 you may need to do this if you get unknown user in the following 1895 step. It never hurts to do it all the time. You may need to 1896 install a new mergemaster (cd src/usr.sbin/mergemaster && make 1897 install) after the buildworld before this step if you last updated 1898 from current before 20130425 or from -stable before 20130430. 1899 1900 [6] This only deletes old files and directories. Old libraries 1901 can be deleted by "make delete-old-libs", but you have to make 1902 sure that no program is using those libraries anymore. 1903 1904 [8] The new kernel must be able to run existing binaries used by 1905 an installworld. When upgrading across major versions, the new 1906 kernel's configuration must include the correct COMPAT_FREEBSD<n> 1907 option for existing binaries (e.g. COMPAT_FREEBSD11 to run 11.x 1908 binaries). Failure to do so may leave you with a system that is 1909 hard to boot to recover. A GENERIC kernel will include suitable 1910 compatibility options to run binaries from older branches. 1911 1912 Make sure that you merge any new devices from GENERIC since the 1913 last time you updated your kernel config file. 1914 1915 [9] If CPUTYPE is defined in your /etc/make.conf, make sure to use the 1916 "?=" instead of the "=" assignment operator, so that buildworld can 1917 override the CPUTYPE if it needs to. 1918 1919 MAKEOBJDIRPREFIX must be defined in an environment variable, and 1920 not on the command line, or in /etc/make.conf. buildworld will 1921 warn if it is improperly defined. 1922FORMAT: 1923 1924This file contains a list, in reverse chronological order, of major 1925breakages in tracking -current. It is not guaranteed to be a complete 1926list of such breakages, and only contains entries since September 23, 2011. 1927If you need to see UPDATING entries from before that date, you will need 1928to fetch an UPDATING file from an older FreeBSD release. 1929 1930Copyright information: 1931 1932Copyright 1998-2009 M.
