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 3420190131: 35 Iflib is no longer unconditionally compiled into the kernel. Drivers 36 using iflib and statically compiled into the kernel, now require 37 the 'device iflib' config option. For the same drivers loaded as 38 modules on kernels not having 'device iflib', the iflib.ko module 39 is loaded automatically. 40 4120190125: 42 The IEEE80211_AMPDU_AGE and AH_SUPPORT_AR5416 kernel configuration 43 options no longer exist since r343219 and r343427 respectively; 44 nothing uses them, so they should be just removed from custom 45 kernel config files. 46 4720181230: 48 r342635 changes the way efibootmgr(8) works by requiring users to add 49 the -b (bootnum) parameter for commands where the bootnum was previously 50 specified with each option. For example 'efibootmgr -B 0001' is now 51 'efibootmgr -B -b 0001'. 52 5320181220: 54 r342286 modifies the NFSv4 server so that it obeys vfs.nfsd.nfs_privport 55 in the same as it is applied to NFSv2 and 3. This implies that NFSv4 56 servers that have vfs.nfsd.nfs_privport set will only allow mounts 57 from clients using a reserved port#. Since both the FreeBSD and Linux 58 NFSv4 clients use reserved port#s by default, this should not affect 59 most NFSv4 mounts. 60 6120181219: 62 The XLP config has been removed. We can't support 64-bit atomics in this 63 kernel because it is running in 32-bit mode. XLP users must transition 64 to running a 64-bit kernel (XLP64 or XLPN32). 65 66 The mips GXEMUL support has been removed from FreeBSD. MALTA* + qemu is 67 the preferred emulator today and we don't need two different ones. 68 69 The old sibyte / swarm / Broadcom BCM1250 support has been 70 removed from the mips port. 71 7220181211: 73 Clang, llvm, lld, lldb, compiler-rt and libc++ have been upgraded to 74 7.0.1. Please see the 20141231 entry below for information about 75 prerequisites and upgrading, if you are not already using clang 3.5.0 76 or higher. 77 7820181211: 79 Remove the timed and netdate programs from the base tree. Setting 80 the time with these deamons has been obsolete for over a decade. 81 8220181126: 83 On amd64, arm64 and armv7 (architectures that install LLVM's ld.lld 84 linker as /usr/bin/ld) GNU ld is no longer installed as ld.bfd, as 85 it produces broken binaries when ifuncs are in use. Users needing 86 GNU ld should install the binutils port or package. 87 8820181123: 89 The BSD crtbegin and crtend code has been enabled by default. It has 90 had extensive testing on amd64, arm64, and i386. It can be disabled 91 by building a world with -DWITHOUT_BSD_CRTBEGIN. 92 9320181115: 94 The set of CTM commands (ctm, ctm_smail, ctm_rmail, ctm_dequeue) 95 has been converted to a port (misc/ctm) and will be removed from 96 FreeBSD-13. It is available as a package (ctm) for all supported 97 FreeBSD versions. 98 9920181110: 100 The default newsyslog.conf(5) file has been changed to only include 101 files in /etc/newsyslog.conf.d/ and /usr/local/etc/newsyslog.conf.d/ if 102 the filenames end in '.conf' and do not begin with a '.'. 103 104 You should check the configuration files in these two directories match 105 this naming convention. You can verify which configuration files are 106 being included using the command: 107 $ newsyslog -Nrv 108 10920181015: 110 Ports for the DRM modules have been simplified. Now, amd64 users should 111 just install the drm-kmod port. All others should install 112 drm-legacy-kmod. 113 114 Graphics hardware that's newer than about 2010 usually works with 115 drm-kmod. For hardware older than 2013, however, some users will need 116 to use drm-legacy-kmod if drm-kmod doesn't work for them. Hardware older 117 than 2008 usually only works in drm-legacy-kmod. The graphics team can 118 only commit to hardware made since 2013 due to the complexity of the 119 market and difficulty to test all the older cards effectively. If you 120 have hardware supported by drm-kmod, you are strongly encouraged to use 121 that as you will get better support. 122 123 Other than KPI chasing, drm-legacy-kmod will not be updated. As outlined 124 elsewhere, the drm and drm2 modules will be eliminated from the src base 125 soon (with a limited exception for arm). Please update to the package asap 126 and report any issues to x11@freebsd.org. 127 128 Generally, anybody using the drm*-kmod packages should add 129 WITHOUT_DRM_MODULE=t and WITHOUT_DRM2_MODULE=t to avoid nasty 130 cross-threading surprises, especially with automatic driver 131 loading from X11 startup. These will become the defaults in 13-current 132 shortly. 133 13420181012: 135 The ixlv(4) driver has been renamed to iavf(4). As a consequence, 136 custom kernel and module loading configuration files must be updated 137 accordingly. Moreover, interfaces previous presented as ixlvN to the 138 system are now exposed as iavfN and network configuration files must 139 be adjusted as necessary. 140 14120181009: 142 OpenSSL has been updated to version 1.1.1. This update included 143 additional various API changes througout the base system. It is 144 important to rebuild third-party software after upgrading. The value 145 of __FreeBSD_version has been bumped accordingly. 146 14720181006: 148 The legacy DRM modules and drivers have now been added to the loader's 149 module blacklist, in favor of loading them with kld_list in rc.conf(5). 150 The module blacklist may be overridden with the loader.conf(5) 151 'module_blacklist' variable, but loading them via rc.conf(5) is strongly 152 encouraged. 153 15420181002: 155 The cam(4) based nda(4) driver will be used over nvd(4) by default on 156 powerpc64. You may set 'options NVME_USE_NVD=1' in your kernel conf or 157 loader tunable 'hw.nvme.use_nvd=1' if you wish to use the existing 158 driver. Make sure to edit /boot/etc/kboot.conf and fstab to use the 159 nda device name. 160 16120180913: 162 Reproducible build mode is now on by default, in preparation for 163 FreeBSD 12.0. This eliminates build metadata such as the user, 164 host, and time from the kernel (and uname), unless the working tree 165 corresponds to a modified checkout from a version control system. 166 The previous behavior can be obtained by setting the /etc/src.conf 167 knob WITHOUT_REPRODUCIBLE_BUILD. 168 16920180826: 170 The Yarrow CSPRNG has been removed from the kernel as it has not been 171 supported by its designers since at least 2003. Fortuna has been the 172 default since FreeBSD-11. 173 17420180822: 175 devctl freeze/thaw have gone into the tree, the rc scripts have been 176 updated to use them and devmatch has been changed. You should update 177 kernel, userland and rc scripts all at the same time. 178 17920180818: 180 The default interpreter has been switched from 4th to Lua. 181 LOADER_DEFAULT_INTERP, documented in build(7), will override the default 182 interpreter. If you have custom FORTH code you will need to set 183 LOADER_DEFAULT_INTERP=4th (valid values are 4th, lua or simp) in 184 src.conf for the build. This will create default hard links between 185 loader and loader_4th instead of loader and loader_lua, the new default. 186 If you are using UEFI it will create the proper hard link to loader.efi. 187 188 bhyve uses userboot.so. It remains 4th-only until some issues are solved 189 regarding coexisting with multiple versions of FreeBSD are resolved. 190 19120180815: 192 ls(1) now respects the COLORTERM environment variable used in other 193 systems and software to indicate that a colored terminal is both 194 supported and desired. If ls(1) is suddenly emitting colors, they may 195 be disabled again by either removing the unwanted COLORTERM from your 196 environment, or using `ls --color=never`. The ls(1) specific CLICOLOR 197 may not be observed in a future release. 198 19920180808: 200 The default pager for most commands has been changed to "less". To 201 restore the old behavior, set PAGER="more" and MANPAGER="more -s" in 202 your environment. 203 20420180731: 205 The jedec_ts(4) driver has been removed. A superset of its functionality 206 is available in the jedec_dimm(4) driver, and the manpage for that 207 driver includes migration instructions. If you have "device jedec_ts" 208 in your kernel configuration file, it must be removed. 209 21020180730: 211 amd64/GENERIC now has EFI runtime services, EFIRT, enabled by default. 212 This should have no effect if the kernel is booted via BIOS/legacy boot. 213 EFIRT may be disabled via a loader tunable, efi.rt.disabled, if a system 214 has a buggy firmware that prevents a successful boot due to use of 215 runtime services. 216 21720180727: 218 Atmel AT91RM9200 and AT91SAM9, Cavium CNS 11xx and XScale 219 support has been removed from the tree. These ports were 220 obsolete and/or known to be broken for many years. 221 22220180723: 223 loader.efi has been augmented to participate more fully in the 224 UEFI boot manager protocol. loader.efi will now look at the 225 BootXXXX environment variable to determine if a specific kernel 226 or root partition was specified. XXXX is derived from BootCurrent. 227 efibootmgr(8) manages these standard UEFI variables. 228 22920180720: 230 zfsloader's functionality has now been folded into loader. 231 zfsloader is no longer necessary once you've updated your 232 boot blocks. For a transition period, we will install a 233 hardlink for zfsloader to loader to allow a smooth transition 234 until the boot blocks can be updated (hard link because old 235 zfs boot blocks don't understand symlinks). 236 23720180719: 238 ARM64 now have efifb support, if you want to have serial console 239 on your arm64 board when an screen is connected and the bootloader 240 setup a framebuffer for us to use, just add : 241 boot_serial=YES 242 boot_multicons=YES 243 in /boot/loader.conf 244 For Raspberry Pi 3 (RPI) users, this is needed even if you don't have 245 an screen connected as the firmware will setup a framebuffer are that 246 u-boot will expose as an EFI framebuffer. 247 24820180719: 249 New uid:gid added, ntpd:ntpd (123:123). Be sure to run mergemaster 250 or take steps to update /etc/passwd before doing installworld on 251 existing systems. Do not skip the "mergemaster -Fp" step before 252 installworld, as described in the update procedures near the bottom 253 of this document. Also, rc.d/ntpd now starts ntpd(8) as user ntpd 254 if the new mac_ntpd(4) policy is available, unless ntpd_flags or 255 the ntp config file contain options that change file/dir locations. 256 When such options (e.g., "statsdir" or "crypto") are used, ntpd can 257 still be run as non-root by setting ntpd_user=ntpd in rc.conf, after 258 taking steps to ensure that all required files/dirs are accessible 259 by the ntpd user. 260 26120180717: 262 Big endian arm support has been removed. 263 26420180711: 265 The static environment setup in kernel configs is no longer mutually 266 exclusive with the loader(8) environment by default. In order to 267 restore the previous default behavior of disabling the loader(8) 268 environment if a static environment is present, you must specify 269 loader_env.disabled=1 in the static environment. 270 27120180705: 272 The ABI of syscalls used by management tools like sockstat and 273 netstat has been broken to allow 32-bit binaries to work on 274 64-bit kernels without modification. These programs will need 275 to match the kernel in order to function. External programs may 276 require minor modifications to accommodate a change of type in 277 structures from pointers to 64-bit virtual addresses. 278 27920180702: 280 On i386 and amd64 atomics are now inlined. Out of tree modules using 281 atomics will need to be rebuilt. 282 28320180701: 284 The '%I' format in the kern.corefile sysctl limits the number of 285 core files that a process can generate to the number stored in the 286 debug.ncores sysctl. The '%I' format is replaced by the single digit 287 index. Previously, if all indexes were taken the kernel would overwrite 288 only a core file with the highest index in a filename. 289 Currently the system will create a new core file if there is a free 290 index or if all slots are taken it will overwrite the oldest one. 291 29220180630: 293 Clang, llvm, lld, lldb, compiler-rt and libc++ have been upgraded to 294 6.0.1. Please see the 20141231 entry below for information about 295 prerequisites and upgrading, if you are not already using clang 3.5.0 296 or higher. 297 29820180628: 299 r335753 introduced a new quoting method. However, etc/devd/devmatch.conf 300 needed to be changed to work with it. This change was made with r335763 301 and requires a mergemaster / etcupdate / etc to update the installed file. 302 30320180612: 304 r334930 changed the interface between the NFS modules, so they all 305 need to be rebuilt. r335018 did a __FreeBSD_version bump for this. 306 30720180530: 308 As of r334391 lld is the default amd64 system linker; it is installed 309 as /usr/bin/ld. Kernel build workarounds (see 20180510 entry) are no 310 longer necessary. 311 31220180530: 313 The kernel / userland interface for devinfo changed, so you'll 314 need a new kernel and userland as a pair for it to work (rebuilding 315 lib/libdevinfo is all that's required). devinfo and devmatch will 316 not work, but everything else will when there's a mismatch. 317 31820180523: 319 The on-disk format for hwpmc callchain records has changed to include 320 threadid corresponding to a given record. This changes the field offsets 321 and thus requires that libpmcstat be rebuilt before using a kernel 322 later than r334108. 323 32420180517: 325 The vxge(4) driver has been removed. This driver was introduced into 326 HEAD one week before the Exar left the Ethernet market and is not 327 known to be used. If you have device vxge in your kernel config file 328 it must be removed. 329 33020180510: 331 The amd64 kernel now requires a ld that supports ifunc to produce a 332 working kernel, either lld or a newer binutils. lld is built by default 333 on amd64, and the 'buildkernel' target uses it automatically. However, 334 it is not the default linker, so building the kernel the traditional 335 way requires LD=ld.lld on the command line (or LD=/usr/local/bin/ld for 336 binutils port/package). lld will soon be default, and this requirement 337 will go away. 338 339 NOTE: As of r334391 lld is the default system linker on amd64, and no 340 workaround is necessary. 341 34220180508: 343 The nxge(4) driver has been removed. This driver was for PCI-X 10g 344 cards made by s2io/Neterion. The company was aquired by Exar and 345 no longer sells or supports Ethernet products. If you have device 346 nxge in your kernel config file it must be removed. 347 34820180504: 349 The tz database (tzdb) has been updated to 2018e. This version more 350 correctly models time stamps in time zones with negative DST such as 351 Europe/Dublin (from 1971 on), Europe/Prague (1946/7), and 352 Africa/Windhoek (1994/2017). This does not affect the UT offsets, only 353 time zone abbreviations and the tm_isdst flag. 354 35520180502: 356 The ixgb(4) driver has been removed. This driver was for an early and 357 uncommon legacy PCI 10GbE for a single ASIC, Intel 82597EX. Intel 358 quickly shifted to the long lived ixgbe family. If you have device 359 ixgb in your kernel config file it must be removed. 360 36120180501: 362 The lmc(4) driver has been removed. This was a WAN interface 363 card that was already reportedly rare in 2003, and had an ambiguous 364 license. If you have device lmc in your kernel config file it must 365 be removed. 366 36720180413: 368 Support for Arcnet networks has been removed. If you have device 369 arcnet or device cm in your kernel config file they must be 370 removed. 371 37220180411: 373 Support for FDDI networks has been removed. If you have device 374 fddi or device fpa in your kernel config file they must be 375 removed. 376 37720180406: 378 In addition to supporting RFC 3164 formatted messages, the 379 syslogd(8) service is now capable of parsing RFC 5424 formatted 380 log messages. The main benefit of using RFC 5424 is that clients 381 may now send log messages with timestamps containing year numbers, 382 microseconds and time zone offsets. 383 384 Similarly, the syslog(3) C library function has been altered to 385 send RFC 5424 formatted messages to the local system logging 386 daemon. On systems using syslogd(8), this change should have no 387 negative impact, as long as syslogd(8) and the C library are 388 updated at the same time. On systems using a different system 389 logging daemon, it may be necessary to make configuration 390 adjustments, depending on the software used. 391 392 When using syslog-ng, add the 'syslog-protocol' flag to local 393 input sources to enable parsing of RFC 5424 formatted messages: 394 395 source src { 396 unix-dgram("/var/run/log" flags(syslog-protocol)); 397 } 398 399 When using rsyslog, disable the 'SysSock.UseSpecialParser' option 400 of the 'imuxsock' module to let messages be processed by the 401 regular RFC 3164/5424 parsing pipeline: 402 403 module(load="imuxsock" SysSock.UseSpecialParser="off") 404 405 Do note that these changes only affect communication between local 406 applications and syslogd(8). The format that syslogd(8) uses to 407 store messages on disk or forward messages to other systems 408 remains unchanged. syslogd(8) still uses RFC 3164 for these 409 purposes. Options to customize this behaviour will be added in the 410 future. Utilities that process log files stored in /var/log are 411 thus expected to continue to function as before. 412 413 __FreeBSD_version has been incremented to 1200061 to denote this 414 change. 415 41620180328: 417 Support for token ring networks has been removed. If you 418 have "device token" in your kernel config you should remove 419 it. No device drivers supported token ring. 420 42120180323: 422 makefs was modified to be able to tag ISO9660 El Torito boot catalog 423 entries as EFI instead of overloading the i386 tag as done previously. 424 The amd64 mkisoimages.sh script used to build amd64 ISO images for 425 release was updated to use this. This may mean that makefs must be 426 updated before "make cdrom" can be run in the release directory. This 427 should be as simple as: 428 429 $ cd $SRCDIR/usr.sbin/makefs 430 $ make depend all install 431 43220180212: 433 FreeBSD boot loader enhanced with Lua scripting. It's purely opt-in for 434 now by building WITH_LOADER_LUA and WITHOUT_FORTH in /etc/src.conf. 435 Co-existance for the transition period will come shortly. Booting is a 436 complex environment and test coverage for Lua-enabled loaders has been 437 thin, so it would be prudent to assume it might not work and make 438 provisions for backup boot methods. 439 44020180211: 441 devmatch functionality has been turned on in devd. It will automatically 442 load drivers for unattached devices. This may cause unexpected drivers to 443 be loaded. Please report any problems to current@ and imp@freebsd.org. 444 44520180114: 446 Clang, llvm, lld, lldb, compiler-rt and libc++ have been upgraded to 447 6.0.0. Please see the 20141231 entry below for information about 448 prerequisites and upgrading, if you are not already using clang 3.5.0 449 or higher. 450 45120180110: 452 LLVM's lld linker is now used as the FreeBSD/amd64 bootstrap linker. 453 This means it is used to link the kernel and userland libraries and 454 executables, but is not yet installed as /usr/bin/ld by default. 455 456 To revert to ld.bfd as the bootstrap linker, in /etc/src.conf set 457 WITHOUT_LLD_BOOTSTRAP=yes 458 45920180110: 460 On i386, pmtimer has been removed. Its functionality has been folded 461 into apm. It was a no-op on ACPI in current for a while now (but was still 462 needed on i386 in FreeBSD 11 and earlier). Users may need to remove it 463 from kernel config files. 464 46520180104: 466 The use of RSS hash from the network card aka flowid has been 467 disabled by default for lagg(4) as it's currently incompatible with 468 the lacp and loadbalance protocols. 469 470 This can be re-enabled by setting the following in loader.conf: 471 net.link.lagg.default_use_flowid="1" 472 47320180102: 474 The SW_WATCHDOG option is no longer necessary to enable the 475 hardclock-based software watchdog if no hardware watchdog is 476 configured. As before, SW_WATCHDOG will cause the software 477 watchdog to be enabled even if a hardware watchdog is configured. 478 47920171215: 480 r326887 fixes the issue described in the 20171214 UPDATING entry. 481 r326888 flips the switch back to building GELI support always. 482 48320171214: 484 r362593 broke ZFS + GELI support for reasons unknown. However, 485 it also broke ZFS support generally, so GELI has been turned off 486 by default as the lesser evil in r326857. If you boot off ZFS and/or 487 GELI, it might not be a good time to update. 488 48920171125: 490 PowerPC users must update loader(8) by rebuilding world before 491 installing a new kernel, as the protocol connecting them has 492 changed. Without the update, loader metadata will not be passed 493 successfully to the kernel and users will have to enter their 494 root partition at the kernel mountroot prompt to continue booting. 495 Newer versions of loader can boot old kernels without issue. 496 49720171110: 498 The LOADER_FIREWIRE_SUPPORT build variable as been renamed to 499 WITH/OUT_LOADER_FIREWIRE. LOADER_{NO_,}GELI_SUPPORT has been renamed 500 to WITH/OUT_LOADER_GELI. 501 50220171106: 503 The naive and non-compliant support of posix_fallocate(2) in ZFS 504 has been removed as of r325320. The system call now returns EINVAL 505 when used on a ZFS file. Although the new behavior complies with the 506 standard, some consumers are not prepared to cope with it. 507 One known victim is lld prior to r325420. 508 50920171102: 510 Building in a FreeBSD src checkout will automatically create object 511 directories now rather than store files in the current directory if 512 'make obj' was not ran. Calling 'make obj' is no longer necessary. 513 This feature can be disabled by setting WITHOUT_AUTO_OBJ=yes in 514 /etc/src-env.conf (not /etc/src.conf), or passing the option in the 515 environment. 516 51720171101: 518 The default MAKEOBJDIR has changed from /usr/obj/<srcdir> for native 519 builds, and /usr/obj/<arch>/<srcdir> for cross-builds, to a unified 520 /usr/obj/<srcdir>/<arch>. This behavior can be changed to the old 521 format by setting WITHOUT_UNIFIED_OBJDIR=yes in /etc/src-env.conf, 522 the environment, or with -DWITHOUT_UNIFIED_OBJDIR when building. 523 The UNIFIED_OBJDIR option is a transitional feature that will be 524 removed for 12.0 release; please migrate to the new format for any 525 tools by looking up the OBJDIR used by 'make -V .OBJDIR' means rather 526 than hardcoding paths. 527 52820171028: 529 The native-xtools target no longer installs the files by default to the 530 OBJDIR. Use the native-xtools-install target with a DESTDIR to install 531 to ${DESTDIR}/${NXTP} where NXTP defaults to /nxb-bin. 532 53320171021: 534 As part of the boot loader infrastructure cleanup, LOADER_*_SUPPORT 535 options are changing from controlling the build if defined / undefined 536 to controlling the build with explicit 'yes' or 'no' values. They will 537 shift to WITH/WITHOUT options to match other options in the system. 538 53920171010: 540 libstand has turned into a private library for sys/boot use only. 541 It is no longer supported as a public interface outside of sys/boot. 542 54320171005: 544 The arm port has split armv6 into armv6 and armv7. armv7 is now 545 a valid TARGET_ARCH/MACHINE_ARCH setting. If you have an armv7 system 546 and are running a kernel from before r324363, you will need to add 547 MACHINE_ARCH=armv7 to 'make buildworld' to do a native build. 548 54920171003: 550 When building multiple kernels using KERNCONF, non-existent KERNCONF 551 files will produce an error and buildkernel will fail. Previously 552 missing KERNCONF files silently failed giving no indication as to 553 why, only to subsequently discover during installkernel that the 554 desired kernel was never built in the first place. 555 55620170912: 557 The default serial number format for CTL LUNs has changed. This will 558 affect users who use /dev/diskid/* device nodes, or whose FibreChannel 559 or iSCSI clients care about their LUNs' serial numbers. Users who 560 require serial number stability should hardcode serial numbers in 561 /etc/ctl.conf . 562 56320170912: 564 For 32-bit arm compiled for hard-float support, soft-floating point 565 binaries now always get their shared libraries from 566 LD_SOFT_LIBRARY_PATH (in the past, this was only used if 567 /usr/libsoft also existed). Only users with a hard-float ld.so, but 568 soft-float everything else should be affected. 569 57020170826: 571 The geli password typed at boot is now hidden. To restore the previous 572 behavior, see geli(8) for configuration options. 573 57420170825: 575 Move PMTUD blackhole counters to TCPSTATS and remove them from bare 576 sysctl values. Minor nit, but requires a rebuild of both world/kernel 577 to complete. 578 57920170814: 580 "make check" behavior (made in ^/head@r295380) has been changed to 581 execute from a limited sandbox, as opposed to executing from 582 ${TESTSDIR}. 583 584 Behavioral changes: 585 - The "beforecheck" and "aftercheck" targets are now specified. 586 - ${CHECKDIR} (added in commit noted above) has been removed. 587 - Legacy behavior can be enabled by setting 588 WITHOUT_MAKE_CHECK_USE_SANDBOX in src.conf(5) or the environment. 589 590 If the limited sandbox mode is enabled, "make check" will execute 591 "make distribution", then install, execute the tests, and clean up the 592 sandbox if successful. 593 594 The "make distribution" and "make install" targets are typically run as 595 root to set appropriate permissions and ownership at installation time. 596 The end-user should set "WITH_INSTALL_AS_USER" in src.conf(5) or the 597 environment if executing "make check" with limited sandbox mode using 598 an unprivileged user. 599 60020170808: 601 Since the switch to GPT disk labels, fsck for UFS/FFS has been 602 unable to automatically find alternate superblocks. As of r322297, 603 the information needed to find alternate superblocks has been 604 moved to the end of the area reserved for the boot block. 605 Filesystems created with a newfs of this vintage or later 606 will create the recovery information. If you have a filesystem 607 created prior to this change and wish to have a recovery block 608 created for your filesystem, you can do so by running fsck in 609 foreground mode (i.e., do not use the -p or -y options). As it 610 starts, fsck will ask ``SAVE DATA TO FIND ALTERNATE SUPERBLOCKS'' 611 to which you should answer yes. 612 61320170728: 614 As of r321665, an NFSv4 server configuration that services 615 Kerberos mounts or clients that do not support the uid/gid in 616 owner/owner_group string capability, must explicitly enable 617 the nfsuserd daemon by adding nfsuserd_enable="YES" to the 618 machine's /etc/rc.conf file. 619 62020170722: 621 Clang, llvm, lldb, compiler-rt and libc++ have been upgraded to 5.0.0. 622 Please see the 20141231 entry below for information about prerequisites 623 and upgrading, if you are not already using clang 3.5.0 or higher. 624 62520170701: 626 WITHOUT_RCMDS is now the default. Set WITH_RCMDS if you need the 627 r-commands (rlogin, rsh, etc.) to be built with the base system. 628 62920170625: 630 The FreeBSD/powerpc platform now uses a 64-bit type for time_t. This is 631 a very major ABI incompatible change, so users of FreeBSD/powerpc must 632 be careful when performing source upgrades. It is best to run 633 'make installworld' from an alternate root system, either a live 634 CD/memory stick, or a temporary root partition. Additionally, all ports 635 must be recompiled. powerpc64 is largely unaffected, except in the case 636 of 32-bit compatibility. All 32-bit binaries will be affected. 637 63820170623: 639 Forward compatibility for the "ino64" project have been committed. This 640 will allow most new binaries to run on older kernels in a limited 641 fashion. This prevents many of the common foot-shooting actions in the 642 upgrade as well as the limited ability to roll back the kernel across 643 the ino64 upgrade. Complicated use cases may not work properly, though 644 enough simpler ones work to allow recovery in most situations. 645 64620170620: 647 Switch back to the BSDL dtc (Device Tree Compiler). Set WITH_GPL_DTC 648 if you require the GPL compiler. 649 65020170618: 651 The internal ABI used for communication between the NFS kernel modules 652 was changed by r320085, so __FreeBSD_version was bumped to 653 ensure all the NFS related modules are updated together. 654 65520170617: 656 The ABI of struct event was changed by extending the data 657 member to 64bit and adding ext fields. For upgrade, same 658 precautions as for the entry 20170523 "ino64" must be 659 followed. 660 66120170531: 662 The GNU roff toolchain has been removed from base. To render manpages 663 which are not supported by mandoc(1), man(1) can fallback on GNU roff 664 from ports (and recommends to install it). 665 To render roff(7) documents, consider using GNU roff from ports or the 666 heirloom doctools roff toolchain from ports via pkg install groff or 667 via pkg install heirloom-doctools. 668 66920170524: 670 The ath(4) and ath_hal(4) modules now build piecemeal to allow for 671 smaller runtime footprint builds. This is useful for embedded systems 672 which only require one chipset support. 673 674 If you load it as a module, make sure this is in /boot/loader.conf: 675 676 if_ath_load="YES" 677 678 This will load the HAL, all chip/RF backends and if_ath_pci. 679 If you have if_ath_pci in /boot/loader.conf, ensure it is after 680 if_ath or it will not load any HAL chipset support. 681 682 If you want to selectively load things (eg on ye cheape ARM/MIPS 683 platforms where RAM is at a premium) you should: 684 685 * load ath_hal 686 * load the chip modules in question 687 * load ath_rate, ath_dfs 688 * load ath_main 689 * load if_ath_pci and/or if_ath_ahb depending upon your particular 690 bus bind type - this is where probe/attach is done. 691 692 For further comments/feedback, poke adrian@ . 693 69420170523: 695 The "ino64" 64-bit inode project has been committed, which extends 696 a number of types to 64 bits. Upgrading in place requires care and 697 adherence to the documented upgrade procedure. 698 699 If using a custom kernel configuration ensure that the 700 COMPAT_FREEBSD11 option is included (as during the upgrade the 701 system will be running the ino64 kernel with the existing world). 702 703 For the safest in-place upgrade begin by removing previous build 704 artifacts via "rm -rf /usr/obj/*". Then, carefully follow the 705 full procedure documented below under the heading "To rebuild 706 everything and install it on the current system." Specifically, 707 a reboot is required after installing the new kernel before 708 installing world. 709 71020170424: 711 The NATM framework including the en(4), fatm(4), hatm(4), and 712 patm(4) devices has been removed. Consumers should plan a 713 migration before the end-of-life date for FreeBSD 11. 714 71520170420: 716 GNU diff has been replaced by a BSD licensed diff. Some features of GNU 717 diff has not been implemented, if those are needed a newer version of 718 GNU diff is available via the diffutils package under the gdiff name. 719 72020170413: 721 As of r316810 for ipfilter, keep frags is no longer assumed when 722 keep state is specified in a rule. r316810 aligns ipfilter with 723 documentation in man pages separating keep frags from keep state. 724 This allows keep state to be specified without forcing keep frags 725 and allows keep frags to be specified independently of keep state. 726 To maintain previous behaviour, also specify keep frags with 727 keep state (as documented in ipf.conf.5). 728 72920170407: 730 arm64 builds now use the base system LLD 4.0.0 linker by default, 731 instead of requiring that the aarch64-binutils port or package be 732 installed. To continue using aarch64-binutils, set 733 CROSS_BINUTILS_PREFIX=/usr/local/aarch64-freebsd/bin . 734 73520170405: 736 The UDP optimization in entry 20160818 that added the sysctl 737 net.inet.udp.require_l2_bcast has been reverted. L2 broadcast 738 packets will no longer be treated as L3 broadcast packets. 739 74020170331: 741 Binds and sends to the loopback addresses, IPv6 and IPv4, will now 742 use any explicitly assigned loopback address available in the jail 743 instead of using the first assigned address of the jail. 744 74520170329: 746 The ctl.ko module no longer implements the iSCSI target frontend: 747 cfiscsi.ko does instead. 748 749 If building cfiscsi.ko as a kernel module, the module can be loaded 750 via one of the following methods: 751 - `cfiscsi_load="YES"` in loader.conf(5). 752 - Add `cfiscsi` to `$kld_list` in rc.conf(5). 753 - ctladm(8)/ctld(8), when compiled with iSCSI support 754 (`WITH_ISCSI=yes` in src.conf(5)) 755 756 Please see cfiscsi(4) for more details. 757 75820170316: 759 The mmcsd.ko module now additionally depends on geom_flashmap.ko. 760 Also, mmc.ko and mmcsd.ko need to be a matching pair built from the 761 same source (previously, the dependency of mmcsd.ko on mmc.ko was 762 missing, but mmcsd.ko now will refuse to load if it is incompatible 763 with mmc.ko). 764 76520170315: 766 The syntax of ipfw(8) named states was changed to avoid ambiguity. 767 If you have used named states in the firewall rules, you need to modify 768 them after installworld and before rebooting. Now named states must 769 be prefixed with colon. 770 77120170311: 772 The old drm (sys/dev/drm/) drivers for i915 and radeon have been 773 removed as the userland we provide cannot use them. The KMS version 774 (sys/dev/drm2) supports the same hardware. 775 77620170302: 777 Clang, llvm, lldb, compiler-rt and libc++ have been upgraded to 4.0.0. 778 Please see the 20141231 entry below for information about prerequisites 779 and upgrading, if you are not already using clang 3.5.0 or higher. 780 78120170221: 782 The code that provides support for ZFS .zfs/ directory functionality 783 has been reimplemented. It's not possible now to create a snapshot 784 by mkdir under .zfs/snapshot/. That should be the only user visible 785 change. 786 78720170216: 788 EISA bus support has been removed. The WITH_EISA option is no longer 789 valid. 790 79120170215: 792 MCA bus support has been removed. 793 79420170127: 795 The WITH_LLD_AS_LD / WITHOUT_LLD_AS_LD build knobs have been renamed 796 WITH_LLD_IS_LD / WITHOUT_LLD_IS_LD, for consistency with CLANG_IS_CC. 797 79820170112: 799 The EM_MULTIQUEUE kernel configuration option is deprecated now that 800 the em(4) driver conforms to iflib specifications. 801 80220170109: 803 The igb(4), em(4) and lem(4) ethernet drivers are now implemented via 804 IFLIB. If you have a custom kernel configuration that excludes em(4) 805 but you use igb(4), you need to re-add em(4) to your custom configuration. 806 80720161217: 808 Clang, llvm, lldb, compiler-rt and libc++ have been upgraded to 3.9.1. 809 Please see the 20141231 entry below for information about prerequisites 810 and upgrading, if you are not already using clang 3.5.0 or higher. 811 81220161124: 813 Clang, llvm, lldb, compiler-rt and libc++ have been upgraded to 3.9.0. 814 Please see the 20141231 entry below for information about prerequisites 815 and upgrading, if you are not already using clang 3.5.0 or higher. 816 81720161119: 818 The layout of the pmap structure has changed for powerpc to put the pmap 819 statistics at the front for all CPU variations. libkvm(3) and all tools 820 that link against it need to be recompiled. 821 82220161030: 823 isl(4) and cyapa(4) drivers now require a new driver, 824 chromebook_platform(4), to work properly on Chromebook-class hardware. 825 On other types of hardware the drivers may need to be configured using 826 device hints. Please see the corresponding manual pages for details. 827 82820161017: 829 The urtwn(4) driver was merged into rtwn(4) and now consists of 830 rtwn(4) main module + rtwn_usb(4) and rtwn_pci(4) bus-specific 831 parts. 832 Also, firmware for RTL8188CE was renamed due to possible name 833 conflict (rtwnrtl8192cU(B) -> rtwnrtl8192cE(B)) 834 83520161015: 836 GNU rcs has been removed from base. It is available as packages: 837 - rcs: Latest GPLv3 GNU rcs version. 838 - rcs57: Copy of the latest version of GNU rcs (GPLv2) before it was 839 removed from base. 840 84120161008: 842 Use of the cc_cdg, cc_chd, cc_hd, or cc_vegas congestion control 843 modules now requires that the kernel configuration contain the 844 TCP_HHOOK option. (This option is included in the GENERIC kernel.) 845 84620161003: 847 The WITHOUT_ELFCOPY_AS_OBJCOPY src.conf(5) knob has been retired. 848 ELF Tool Chain's elfcopy is always installed as /usr/bin/objcopy. 849 85020160924: 851 Relocatable object files with the extension of .So have been renamed 852 to use an extension of .pico instead. The purpose of this change is 853 to avoid a name clash with shared libraries on case-insensitive file 854 systems. On those file systems, foo.So is the same file as foo.so. 855 85620160918: 857 GNU rcs has been turned off by default. It can (temporarily) be built 858 again by adding WITH_RCS knob in src.conf. 859 Otherwise, GNU rcs is available from packages: 860 - rcs: Latest GPLv3 GNU rcs version. 861 - rcs57: Copy of the latest version of GNU rcs (GPLv2) from base. 862 86320160918: 864 The backup_uses_rcs functionality has been removed from rc.subr. 865 86620160908: 867 The queue(3) debugging macro, QUEUE_MACRO_DEBUG, has been split into 868 two separate components, QUEUE_MACRO_DEBUG_TRACE and 869 QUEUE_MACRO_DEBUG_TRASH. Define both for the original 870 QUEUE_MACRO_DEBUG behavior. 871 87220160824: 873 r304787 changed some ioctl interfaces between the iSCSI userspace 874 programs and the kernel. ctladm, ctld, iscsictl, and iscsid must be 875 rebuilt to work with new kernels. __FreeBSD_version has been bumped 876 to 1200005. 877 87820160818: 879 The UDP receive code has been updated to only treat incoming UDP 880 packets that were addressed to an L2 broadcast address as L3 881 broadcast packets. It is not expected that this will affect any 882 standards-conforming UDP application. The new behaviour can be 883 disabled by setting the sysctl net.inet.udp.require_l2_bcast to 884 0. 885 88620160818: 887 Remove the openbsd_poll system call. 888 __FreeBSD_version has been bumped because of this. 889 89020160708: 891 The stable/11 branch has been created from head@r302406. 892 89320160622: 894 The libc stub for the pipe(2) system call has been replaced with 895 a wrapper that calls the pipe2(2) system call and the pipe(2) 896 system call is now only implemented by the kernels that include 897 "options COMPAT_FREEBSD10" in their config file (this is the 898 default). Users should ensure that this option is enabled in 899 their kernel or upgrade userspace to r302092 before upgrading their 900 kernel. 901 90220160527: 903 CAM will now strip leading spaces from SCSI disks' serial numbers. 904 This will affect users who create UFS filesystems on SCSI disks using 905 those disk's diskid device nodes. For example, if /etc/fstab 906 previously contained a line like 907 "/dev/diskid/DISK-%20%20%20%20%20%20%20ABCDEFG0123456", you should 908 change it to "/dev/diskid/DISK-ABCDEFG0123456". Users of geom 909 transforms like gmirror may also be affected. ZFS users should 910 generally be fine. 911 91220160523: 913 The bitstring(3) API has been updated with new functionality and 914 improved performance. But it is binary-incompatible with the old API. 915 Objects built with the new headers may not be linked against objects 916 built with the old headers. 917 91820160520: 919 The brk and sbrk functions have been removed from libc on arm64. 920 Binutils from ports has been updated to not link to these 921 functions and should be updated to the latest version before 922 installing a new libc. 923 92420160517: 925 The armv6 port now defaults to hard float ABI. Limited support 926 for running both hardfloat and soft float on the same system 927 is available using the libraries installed with -DWITH_LIBSOFT. 928 This has only been tested as an upgrade path for installworld 929 and packages may fail or need manual intervention to run. New 930 packages will be needed. 931 932 To update an existing self-hosted armv6hf system, you must add 933 TARGET_ARCH=armv6 on the make command line for both the build 934 and the install steps. 935 93620160510: 937 Kernel modules compiled outside of a kernel build now default to 938 installing to /boot/modules instead of /boot/kernel. Many kernel 939 modules built this way (such as those in ports) already overrode 940 KMODDIR explicitly to install into /boot/modules. However, 941 manually building and installing a module from /sys/modules will 942 now install to /boot/modules instead of /boot/kernel. 943 94420160414: 945 The CAM I/O scheduler has been committed to the kernel. There should be 946 no user visible impact. This does enable NCQ Trim on ada SSDs. While the 947 list of known rogues that claim support for this but actually corrupt 948 data is believed to be complete, be on the lookout for data 949 corruption. The known rogue list is believed to be complete: 950 951 o Crucial MX100, M550 drives with MU01 firmware. 952 o Micron M510 and M550 drives with MU01 firmware. 953 o Micron M500 prior to MU07 firmware 954 o Samsung 830, 840, and 850 all firmwares 955 o FCCT M500 all firmwares 956 957 Crucial has firmware http://www.crucial.com/usa/en/support-ssd-firmware 958 with working NCQ TRIM. For Micron branded drives, see your sales rep for 959 updated firmware. Black listed drives will work correctly because these 960 drives work correctly so long as no NCQ TRIMs are sent to them. Given 961 this list is the same as found in Linux, it's believed there are no 962 other rogues in the market place. All other models from the above 963 vendors work. 964 965 To be safe, if you are at all concerned, you can quirk each of your 966 drives to prevent NCQ from being sent by setting: 967 kern.cam.ada.X.quirks="0x2" 968 in loader.conf. If the drive requires the 4k sector quirk, set the 969 quirks entry to 0x3. 970 97120160330: 972 The FAST_DEPEND build option has been removed and its functionality is 973 now the one true way. The old mkdep(1) style of 'make depend' has 974 been removed. See 20160311 for further details. 975 97620160317: 977 Resource range types have grown from unsigned long to uintmax_t. All 978 drivers, and anything using libdevinfo, need to be recompiled. 979 98020160311: 981 WITH_FAST_DEPEND is now enabled by default for in-tree and out-of-tree 982 builds. It no longer runs mkdep(1) during 'make depend', and the 983 'make depend' stage can safely be skipped now as it is auto ran 984 when building 'make all' and will generate all SRCS and DPSRCS before 985 building anything else. Dependencies are gathered at compile time with 986 -MF flags kept in separate .depend files per object file. Users should 987 run 'make cleandepend' once if using -DNO_CLEAN to clean out older 988 stale .depend files. 989 99020160306: 991 On amd64, clang 3.8.0 can now insert sections of type AMD64_UNWIND into 992 kernel modules. Therefore, if you load any kernel modules at boot time, 993 please install the boot loaders after you install the kernel, but before 994 rebooting, e.g.: 995 996 make buildworld 997 make buildkernel KERNCONF=YOUR_KERNEL_HERE 998 make installkernel KERNCONF=YOUR_KERNEL_HERE 999 make -C sys/boot install 1000 <reboot in single user> 1001 1002 Then follow the usual steps, described in the General Notes section, 1003 below. 1004 100520160305: 1006 Clang, llvm, lldb and compiler-rt have been upgraded to 3.8.0. Please 1007 see the 20141231 entry below for information about prerequisites and 1008 upgrading, if you are not already using clang 3.5.0 or higher. 1009 101020160301: 1011 The AIO subsystem is now a standard part of the kernel. The 1012 VFS_AIO kernel option and aio.ko kernel module have been removed. 1013 Due to stability concerns, asynchronous I/O requests are only 1014 permitted on sockets and raw disks by default. To enable 1015 asynchronous I/O requests on all file types, set the 1016 vfs.aio.enable_unsafe sysctl to a non-zero value. 1017 101820160226: 1019 The ELF object manipulation tool objcopy is now provided by the 1020 ELF Tool Chain project rather than by GNU binutils. It should be a 1021 drop-in replacement, with the addition of arm64 support. The 1022 (temporary) src.conf knob WITHOUT_ELFCOPY_AS_OBJCOPY knob may be set 1023 to obtain the GNU version if necessary. 1024 102520160129: 1026 Building ZFS pools on top of zvols is prohibited by default. That 1027 feature has never worked safely; it's always been prone to deadlocks. 1028 Using a zvol as the backing store for a VM guest's virtual disk will 1029 still work, even if the guest is using ZFS. Legacy behavior can be 1030 restored by setting vfs.zfs.vol.recursive=1. 1031 103220160119: 1033 The NONE and HPN patches has been removed from OpenSSH. They are 1034 still available in the security/openssh-portable port. 1035 103620160113: 1037 With the addition of ypldap(8), a new _ypldap user is now required 1038 during installworld. "mergemaster -p" can be used to add the user 1039 prior to installworld, as documented in the handbook. 1040 104120151216: 1042 The tftp loader (pxeboot) now uses the option root-path directive. As a 1043 consequence it no longer looks for a pxeboot.4th file on the tftp 1044 server. Instead it uses the regular /boot infrastructure as with the 1045 other loaders. 1046 104720151211: 1048 The code to start recording plug and play data into the modules has 1049 been committed. While the old tools will properly build a new kernel, 1050 a number of warnings about "unknown metadata record 4" will be produced 1051 for an older kldxref. To avoid such warnings, make sure to rebuild 1052 the kernel toolchain (or world). Make sure that you have r292078 or 1053 later when trying to build 292077 or later before rebuilding. 1054 105520151207: 1056 Debug data files are now built by default with 'make buildworld' and 1057 installed with 'make installworld'. This facilitates debugging but 1058 requires more disk space both during the build and for the installed 1059 world. Debug files may be disabled by setting WITHOUT_DEBUG_FILES=yes 1060 in src.conf(5). 1061 106220151130: 1063 r291527 changed the internal interface between the nfsd.ko and 1064 nfscommon.ko modules. As such, they must both be upgraded to-gether. 1065 __FreeBSD_version has been bumped because of this. 1066 106720151108: 1068 Add support for unicode collation strings leads to a change of 1069 order of files listed by ls(1) for example. To get back to the old 1070 behaviour, set LC_COLLATE environment variable to "C". 1071 1072 Databases administrators will need to reindex their databases given 1073 collation results will be different. 1074 1075 Due to a bug in install(1) it is recommended to remove the ancient 1076 locales before running make installworld. 1077 1078 rm -rf /usr/share/locale/* 1079 108020151030: 1081 The OpenSSL has been upgraded to 1.0.2d. Any binaries requiring 1082 libcrypto.so.7 or libssl.so.7 must be recompiled. 1083 108420151020: 1085 Qlogic 24xx/25xx firmware images were updated from 5.5.0 to 7.3.0. 1086 Kernel modules isp_2400_multi and isp_2500_multi were removed and 1087 should be replaced with isp_2400 and isp_2500 modules respectively. 1088 108920151017: 1090 The build previously allowed using 'make -n' to not recurse into 1091 sub-directories while showing what commands would be executed, and 1092 'make -n -n' to recursively show commands. Now 'make -n' will recurse 1093 and 'make -N' will not. 1094 109520151012: 1096 If you specify SENDMAIL_MC or SENDMAIL_CF in make.conf, mergemaster 1097 and etcupdate will now use this file. A custom sendmail.cf is now 1098 updated via this mechanism rather than via installworld. If you had 1099 excluded sendmail.cf in mergemaster.rc or etcupdate.conf, you may 1100 want to remove the exclusion or change it to "always install". 1101 /etc/mail/sendmail.cf is now managed the same way regardless of 1102 whether SENDMAIL_MC/SENDMAIL_CF is used. If you are not using 1103 SENDMAIL_MC/SENDMAIL_CF there should be no change in behavior. 1104 110520151011: 1106 Compatibility shims for legacy ATA device names have been removed. 1107 It includes ATA_STATIC_ID kernel option, kern.cam.ada.legacy_aliases 1108 and kern.geom.raid.legacy_aliases loader tunables, kern.devalias.* 1109 environment variables, /dev/ad* and /dev/ar* symbolic links. 1110 111120151006: 1112 Clang, llvm, lldb, compiler-rt and libc++ have been upgraded to 3.7.0. 1113 Please see the 20141231 entry below for information about prerequisites 1114 and upgrading, if you are not already using clang 3.5.0 or higher. 1115 111620150924: 1117 Kernel debug files have been moved to /usr/lib/debug/boot/kernel/, 1118 and renamed from .symbols to .debug. This reduces the size requirements 1119 on the boot partition or file system and provides consistency with 1120 userland debug files. 1121 1122 When using the supported kernel installation method the 1123 /usr/lib/debug/boot/kernel directory will be renamed (to kernel.old) 1124 as is done with /boot/kernel. 1125 1126 Developers wishing to maintain the historical behavior of installing 1127 debug files in /boot/kernel/ can set KERN_DEBUGDIR="" in src.conf(5). 1128 112920150827: 1130 The wireless drivers had undergone changes that remove the 'parent 1131 interface' from the ifconfig -l output. The rc.d network scripts 1132 used to check presence of a parent interface in the list, so old 1133 scripts would fail to start wireless networking. Thus, etcupdate(3) 1134 or mergemaster(8) run is required after kernel update, to update your 1135 rc.d scripts in /etc. 1136 113720150827: 1138 pf no longer supports 'scrub fragment crop' or 'scrub fragment drop-ovl' 1139 These configurations are now automatically interpreted as 1140 'scrub fragment reassemble'. 1141 114220150817: 1143 Kernel-loadable modules for the random(4) device are back. To use 1144 them, the kernel must have 1145 1146 device random 1147 options RANDOM_LOADABLE 1148 1149 kldload(8) can then be used to load random_fortuna.ko 1150 or random_yarrow.ko. Please note that due to the indirect 1151 function calls that the loadable modules need to provide, 1152 the build-in variants will be slightly more efficient. 1153 1154 The random(4) kernel option RANDOM_DUMMY has been retired due to 1155 unpopularity. It was not all that useful anyway. 1156 115720150813: 1158 The WITHOUT_ELFTOOLCHAIN_TOOLS src.conf(5) knob has been retired. 1159 Control over building the ELF Tool Chain tools is now provided by 1160 the WITHOUT_TOOLCHAIN knob. 1161 116220150810: 1163 The polarity of Pulse Per Second (PPS) capture events with the 1164 uart(4) driver has been corrected. Prior to this change the PPS 1165 "assert" event corresponded to the trailing edge of a positive PPS 1166 pulse and the "clear" event was the leading edge of the next pulse. 1167 1168 As the width of a PPS pulse in a typical GPS receiver is on the 1169 order of 1 millisecond, most users will not notice any significant 1170 difference with this change. 1171 1172 Anyone who has compensated for the historical polarity reversal by 1173 configuring a negative offset equal to the pulse width will need to 1174 remove that workaround. 1175 117620150809: 1177 The default group assigned to /dev/dri entries has been changed 1178 from 'wheel' to 'video' with the id of '44'. If you want to have 1179 access to the dri devices please add yourself to the video group 1180 with: 1181 1182 # pw groupmod video -m $USER 1183 118420150806: 1185 The menu.rc and loader.rc files will now be replaced during 1186 upgrades. Please migrate local changes to menu.rc.local and 1187 loader.rc.local instead. 1188 118920150805: 1190 GNU Binutils versions of addr2line, c++filt, nm, readelf, size, 1191 strings and strip have been removed. The src.conf(5) knob 1192 WITHOUT_ELFTOOLCHAIN_TOOLS no longer provides the binutils tools. 1193 119420150728: 1195 As ZFS requires more kernel stack pages than is the default on some 1196 architectures e.g. i386, it now warns if KSTACK_PAGES is less than 1197 ZFS_MIN_KSTACK_PAGES (which is 4 at the time of writing). 1198 1199 Please consider using 'options KSTACK_PAGES=X' where X is greater 1200 than or equal to ZFS_MIN_KSTACK_PAGES i.e. 4 in such configurations. 1201 120220150706: 1203 sendmail has been updated to 8.15.2. Starting with FreeBSD 11.0 1204 and sendmail 8.15, sendmail uses uncompressed IPv6 addresses by 1205 default, i.e., they will not contain "::". For example, instead 1206 of ::1, it will be 0:0:0:0:0:0:0:1. This permits a zero subnet 1207 to have a more specific match, such as different map entries for 1208 IPv6:0:0 vs IPv6:0. This change requires that configuration 1209 data (including maps, files, classes, custom ruleset, etc.) must 1210 use the same format, so make certain such configuration data is 1211 upgrading. As a very simple check search for patterns like 1212 'IPv6:[0-9a-fA-F:]*::' and 'IPv6::'. To return to the old 1213 behavior, set the m4 option confUSE_COMPRESSED_IPV6_ADDRESSES or 1214 the cf option UseCompressedIPv6Addresses. 1215 121620150630: 1217 The default kernel entropy-processing algorithm is now 1218 Fortuna, replacing Yarrow. 1219 1220 Assuming you have 'device random' in your kernel config 1221 file, the configurations allow a kernel option to override 1222 this default. You may choose *ONE* of: 1223 1224 options RANDOM_YARROW # Legacy /dev/random algorithm. 1225 options RANDOM_DUMMY # Blocking-only driver. 1226 1227 If you have neither, you get Fortuna. For most people, 1228 read no further, Fortuna will give a /dev/random that works 1229 like it always used to, and the difference will be irrelevant. 1230 1231 If you remove 'device random', you get *NO* kernel-processed 1232 entropy at all. This may be acceptable to folks building 1233 embedded systems, but has complications. Carry on reading, 1234 and it is assumed you know what you need. 1235 1236 *PLEASE* read random(4) and random(9) if you are in the 1237 habit of tweaking kernel configs, and/or if you are a member 1238 of the embedded community, wanting specific and not-usual 1239 behaviour from your security subsystems. 1240 1241 NOTE!! If you use RANDOM_DUMMY and/or have no 'device 1242 random', you will NOT have a functioning /dev/random, and 1243 many cryptographic features will not work, including SSH. 1244 You may also find strange behaviour from the random(3) set 1245 of library functions, in particular sranddev(3), srandomdev(3) 1246 and arc4random(3). The reason for this is that the KERN_ARND 1247 sysctl only returns entropy if it thinks it has some to 1248 share, and with RANDOM_DUMMY or no 'device random' this 1249 will never happen. 1250 125120150623: 1252 An additional fix for the issue described in the 20150614 sendmail 1253 entry below has been committed in revision 284717. 1254 125520150616: 1256 FreeBSD's old make (fmake) has been removed from the system. It is 1257 available as the devel/fmake port or via pkg install fmake. 1258 125920150615: 1260 The fix for the issue described in the 20150614 sendmail entry 1261 below has been committed in revision 284436. The work 1262 around described in that entry is no longer needed unless the 1263 default setting is overridden by a confDH_PARAMETERS configuration 1264 setting of '5' or pointing to a 512 bit DH parameter file. 1265 126620150614: 1267 ALLOW_DEPRECATED_ATF_TOOLS/ATFFILE support has been removed from 1268 atf.test.mk (included from bsd.test.mk). Please upgrade devel/atf 1269 and devel/kyua to version 0.20+ and adjust any calling code to work 1270 with Kyuafile and kyua. 1271 127220150614: 1273 The import of openssl to address the FreeBSD-SA-15:10.openssl 1274 security advisory includes a change which rejects handshakes 1275 with DH parameters below 768 bits. sendmail releases prior 1276 to 8.15.2 (not yet released), defaulted to a 512 bit 1277 DH parameter setting for client connections. To work around 1278 this interoperability, sendmail can be configured to use a 1279 2048 bit DH parameter by: 1280 1281 1. Edit /etc/mail/`hostname`.mc 1282 2. If a setting for confDH_PARAMETERS does not exist or 1283 exists and is set to a string beginning with '5', 1284 replace it with '2'. 1285 3. If a setting for confDH_PARAMETERS exists and is set to 1286 a file path, create a new file with: 1287 openssl dhparam -out /path/to/file 2048 1288 4. Rebuild the .cf file: 1289 cd /etc/mail/; make; make install 1290 5. Restart sendmail: 1291 cd /etc/mail/; make restart 1292 1293 A sendmail patch is coming, at which time this file will be 1294 updated. 1295 129620150604: 1297 Generation of legacy formatted entries have been disabled by default 1298 in pwd_mkdb(8), as all base system consumers of the legacy formatted 1299 entries were converted to use the new format by default when the new, 1300 machine independent format have been added and supported since FreeBSD 1301 5.x. 1302 1303 Please see the pwd_mkdb(8) manual page for further details. 1304 130520150525: 1306 Clang and llvm have been upgraded to 3.6.1 release. Please see the 1307 20141231 entry below for information about prerequisites and upgrading, 1308 if you are not already using 3.5.0 or higher. 1309 131020150521: 1311 TI platform code switched to using vendor DTS files and this update 1312 may break existing systems running on Beaglebone, Beaglebone Black, 1313 and Pandaboard: 1314 1315 - dtb files should be regenerated/reinstalled. Filenames are the 1316 same but content is different now 1317 - GPIO addressing was changed, now each GPIO bank (32 pins per bank) 1318 has its own /dev/gpiocX device, e.g. pin 121 on /dev/gpioc0 in old 1319 addressing scheme is now pin 25 on /dev/gpioc3. 1320 - Pandaboard: /etc/ttys should be updated, serial console device is 1321 now /dev/ttyu2, not /dev/ttyu0 1322 132320150501: 1324 soelim(1) from gnu/usr.bin/groff has been replaced by usr.bin/soelim. 1325 If you need the GNU extension from groff soelim(1), install groff 1326 from package: pkg install groff, or via ports: textproc/groff. 1327 132820150423: 1329 chmod, chflags, chown and chgrp now affect symlinks in -R mode as 1330 defined in symlink(7); previously symlinks were silently ignored. 1331 133220150415: 1333 The const qualifier has been removed from iconv(3) to comply with 1334 POSIX. The ports tree is aware of this from r384038 onwards. 1335 133620150416: 1337 Libraries specified by LIBADD in Makefiles must have a corresponding 1338 DPADD_<lib> variable to ensure correct dependencies. This is now 1339 enforced in src.libnames.mk. 1340 134120150324: 1342 From legacy ata(4) driver was removed support for SATA controllers 1343 supported by more functional drivers ahci(4), siis(4) and mvs(4). 1344 Kernel modules ataahci and ataadaptec were removed completely, 1345 replaced by ahci and mvs modules respectively. 1346 134720150315: 1348 Clang, llvm and lldb have been upgraded to 3.6.0 release. Please see 1349 the 20141231 entry below for information about prerequisites and 1350 upgrading, if you are not already using 3.5.0 or higher. 1351 135220150307: 1353 The 32-bit PowerPC kernel has been changed to a position-independent 1354 executable. This can only be booted with a version of loader(8) 1355 newer than January 31, 2015, so make sure to update both world and 1356 kernel before rebooting. 1357 135820150217: 1359 If you are running a -CURRENT kernel since r273872 (Oct 30th, 2014), 1360 but before r278950, the RNG was not seeded properly. Immediately 1361 upgrade the kernel to r278950 or later and regenerate any keys (e.g. 1362 ssh keys or openssl keys) that were generated w/ a kernel from that 1363 range. This does not affect programs that directly used /dev/random 1364 or /dev/urandom. All userland uses of arc4random(3) are affected. 1365 136620150210: 1367 The autofs(4) ABI was changed in order to restore binary compatibility 1368 with 10.1-RELEASE. The automountd(8) daemon needs to be rebuilt to work 1369 with the new kernel. 1370 137120150131: 1372 The powerpc64 kernel has been changed to a position-independent 1373 executable. This can only be booted with a new version of loader(8), 1374 so make sure to update both world and kernel before rebooting. 1375 137620150118: 1377 Clang and llvm have been upgraded to 3.5.1 release. This is a bugfix 1378 only release, no new features have been added. Please see the 20141231 1379 entry below for information about prerequisites and upgrading, if you 1380 are not already using 3.5.0. 1381 138220150107: 1383 ELF tools addr2line, elfcopy (strip), nm, size, and strings are now 1384 taken from the ELF Tool Chain project rather than GNU binutils. They 1385 should be drop-in replacements, with the addition of arm64 support. 1386 The WITHOUT_ELFTOOLCHAIN_TOOLS= knob may be used to obtain the 1387 binutils tools, if necessary. See 20150805 for updated information. 1388 138920150105: 1390 The default Unbound configuration now enables remote control 1391 using a local socket. Users who have already enabled the 1392 local_unbound service should regenerate their configuration 1393 by running "service local_unbound setup" as root. 1394 139520150102: 1396 The GNU texinfo and GNU info pages have been removed. 1397 To be able to view GNU info pages please install texinfo from ports. 1398 139920141231: 1400 Clang, llvm and lldb have been upgraded to 3.5.0 release. 1401 1402 As of this release, a prerequisite for building clang, llvm and lldb is 1403 a C++11 capable compiler and C++11 standard library. This means that to 1404 be able to successfully build the cross-tools stage of buildworld, with 1405 clang as the bootstrap compiler, your system compiler or cross compiler 1406 should either be clang 3.3 or later, or gcc 4.8 or later, and your 1407 system C++ library should be libc++, or libdstdc++ from gcc 4.8 or 1408 later. 1409 1410 On any standard FreeBSD 10.x or 11.x installation, where clang and 1411 libc++ are on by default (that is, on x86 or arm), this should work out 1412 of the box. 1413 1414 On 9.x installations where clang is enabled by default, e.g. on x86 and 1415 powerpc, libc++ will not be enabled by default, so libc++ should be 1416 built (with clang) and installed first. If both clang and libc++ are 1417 missing, build clang first, then use it to build libc++. 1418 1419 On 8.x and earlier installations, upgrade to 9.x first, and then follow 1420 the instructions for 9.x above. 1421 1422 Sparc64 and mips users are unaffected, as they still use gcc 4.2.1 by 1423 default, and do not build clang. 1424 1425 Many embedded systems are resource constrained, and will not be able to 1426 build clang in a reasonable time, or in some cases at all. In those 1427 cases, cross building bootable systems on amd64 is a workaround. 1428 1429 This new version of clang introduces a number of new warnings, of which 1430 the following are most likely to appear: 1431 1432 -Wabsolute-value 1433 1434 This warns in two cases, for both C and C++: 1435 * When the code is trying to take the absolute value of an unsigned 1436 quantity, which is effectively a no-op, and almost never what was 1437 intended. The code should be fixed, if at all possible. If you are 1438 sure that the unsigned quantity can be safely cast to signed, without 1439 loss of information or undefined behavior, you can add an explicit 1440 cast, or disable the warning. 1441 1442 * When the code is trying to take an absolute value, but the called 1443 abs() variant is for the wrong type, which can lead to truncation. 1444 If you want to disable the warning instead of fixing the code, please 1445 make sure that truncation will not occur, or it might lead to unwanted 1446 side-effects. 1447 1448 -Wtautological-undefined-compare and 1449 -Wundefined-bool-conversion 1450 1451 These warn when C++ code is trying to compare 'this' against NULL, while 1452 'this' should never be NULL in well-defined C++ code. However, there is 1453 some legacy (pre C++11) code out there, which actively abuses this 1454 feature, which was less strictly defined in previous C++ versions. 1455 1456 Squid and openjdk do this, for example. The warning can be turned off 1457 for C++98 and earlier, but compiling the code in C++11 mode might result 1458 in unexpected behavior; for example, the parts of the program that are 1459 unreachable could be optimized away. 1460 146120141222: 1462 The old NFS client and server (kernel options NFSCLIENT, NFSSERVER) 1463 kernel sources have been removed. The .h files remain, since some 1464 utilities include them. This will need to be fixed later. 1465 If "mount -t oldnfs ..." is attempted, it will fail. 1466 If the "-o" option on mountd(8), nfsd(8) or nfsstat(1) is used, 1467 the utilities will report errors. 1468 146920141121: 1470 The handling of LOCAL_LIB_DIRS has been altered to skip addition of 1471 directories to top level SUBDIR variable when their parent 1472 directory is included in LOCAL_DIRS. Users with build systems with 1473 such hierarchies and without SUBDIR entries in the parent 1474 directory Makefiles should add them or add the directories to 1475 LOCAL_DIRS. 1476 147720141109: 1478 faith(4) and faithd(8) have been removed from the base system. Faith 1479 has been obsolete for a very long time. 1480 148120141104: 1482 vt(4), the new console driver, is enabled by default. It brings 1483 support for Unicode and double-width characters, as well as 1484 support for UEFI and integration with the KMS kernel video 1485 drivers. 1486 1487 You may need to update your console settings in /etc/rc.conf, 1488 most probably the keymap. During boot, /etc/rc.d/syscons will 1489 indicate what you need to do. 1490 1491 vt(4) still has issues and lacks some features compared to 1492 syscons(4). See the wiki for up-to-date information: 1493 https://wiki.freebsd.org/Newcons 1494 1495 If you want to keep using syscons(4), you can do so by adding 1496 the following line to /boot/loader.conf: 1497 kern.vty=sc 1498 149920141102: 1500 pjdfstest has been integrated into kyua as an opt-in test suite. 1501 Please see share/doc/pjdfstest/README for more details on how to 1502 execute it. 1503 150420141009: 1505 gperf has been removed from the base system for architectures 1506 that use clang. Ports that require gperf will obtain it from the 1507 devel/gperf port. 1508 150920140923: 1510 pjdfstest has been moved from tools/regression/pjdfstest to 1511 contrib/pjdfstest . 1512 151320140922: 1514 At svn r271982, The default linux compat kernel ABI has been adjusted 1515 to 2.6.18 in support of the linux-c6 compat ports infrastructure 1516 update. If you wish to continue using the linux-f10 compat ports, 1517 add compat.linux.osrelease=2.6.16 to your local sysctl.conf. Users are 1518 encouraged to update their linux-compat packages to linux-c6 during 1519 their next update cycle. 1520 152120140729: 1522 The ofwfb driver, used to provide a graphics console on PowerPC when 1523 using vt(4), no longer allows mmap() of all physical memory. This 1524 will prevent Xorg on PowerPC with some ATI graphics cards from 1525 initializing properly unless x11-servers/xorg-server is updated to 1526 1.12.4_8 or newer. 1527 152820140723: 1529 The xdev targets have been converted to using TARGET and 1530 TARGET_ARCH instead of XDEV and XDEV_ARCH. 1531 153220140719: 1533 The default unbound configuration has been modified to address 1534 issues with reverse lookups on networks that use private 1535 address ranges. If you use the local_unbound service, run 1536 "service local_unbound setup" as root to regenerate your 1537 configuration, then "service local_unbound reload" to load the 1538 new configuration. 1539 154020140709: 1541 The GNU texinfo and GNU info pages are not built and installed 1542 anymore, WITH_INFO knob has been added to allow to built and install 1543 them again. 1544 UPDATE: see 20150102 entry on texinfo's removal 1545 154620140708: 1547 The GNU readline library is now an INTERNALLIB - that is, it is 1548 statically linked into consumers (GDB and variants) in the base 1549 system, and the shared library is no longer installed. The 1550 devel/readline port is available for third party software that 1551 requires readline. 1552 155320140702: 1554 The Itanium architecture (ia64) has been removed from the list of 1555 known architectures. This is the first step in the removal of the 1556 architecture. 1557 155820140701: 1559 Commit r268115 has added NFSv4.1 server support, merged from 1560 projects/nfsv4.1-server. Since this includes changes to the 1561 internal interfaces between the NFS related modules, a full 1562 build of the kernel and modules will be necessary. 1563 __FreeBSD_version has been bumped. 1564 156520140629: 1566 The WITHOUT_VT_SUPPORT kernel config knob has been renamed 1567 WITHOUT_VT. (The other _SUPPORT knobs have a consistent meaning 1568 which differs from the behaviour controlled by this knob.) 1569 157020140619: 1571 Maximal length of the serial number in CTL was increased from 16 to 1572 64 chars, that breaks ABI. All CTL-related tools, such as ctladm 1573 and ctld, need to be rebuilt to work with a new kernel. 1574 157520140606: 1576 The libatf-c and libatf-c++ major versions were downgraded to 0 and 1577 1 respectively to match the upstream numbers. They were out of 1578 sync because, when they were originally added to FreeBSD, the 1579 upstream versions were not respected. These libraries are private 1580 and not yet built by default, so renumbering them should be a 1581 non-issue. However, unclean source trees will yield broken test 1582 programs once the operator executes "make delete-old-libs" after a 1583 "make installworld". 1584 1585 Additionally, the atf-sh binary was made private by moving it into 1586 /usr/libexec/. Already-built shell test programs will keep the 1587 path to the old binary so they will break after "make delete-old" 1588 is run. 1589 1590 If you are using WITH_TESTS=yes (not the default), wipe the object 1591 tree and rebuild from scratch to prevent spurious test failures. 1592 This is only needed once: the misnumbered libraries and misplaced 1593 binaries have been added to OptionalObsoleteFiles.inc so they will 1594 be removed during a clean upgrade. 1595 159620140512: 1597 Clang and llvm have been upgraded to 3.4.1 release. 1598 159920140508: 1600 We bogusly installed src.opts.mk in /usr/share/mk. This file should 1601 be removed to avoid issues in the future (and has been added to 1602 ObsoleteFiles.inc). 1603 160420140505: 1605 /etc/src.conf now affects only builds of the FreeBSD src tree. In the 1606 past, it affected all builds that used the bsd.*.mk files. The old 1607 behavior was a bug, but people may have relied upon it. To get this 1608 behavior back, you can .include /etc/src.conf from /etc/make.conf 1609 (which is still global and isn't changed). This also changes the 1610 behavior of incremental builds inside the tree of individual 1611 directories. Set MAKESYSPATH to ".../share/mk" to do that. 1612 Although this has survived make universe and some upgrade scenarios, 1613 other upgrade scenarios may have broken. At least one form of 1614 temporary breakage was fixed with MAKESYSPATH settings for buildworld 1615 as well... In cases where MAKESYSPATH isn't working with this 1616 setting, you'll need to set it to the full path to your tree. 1617 1618 One side effect of all this cleaning up is that bsd.compiler.mk 1619 is no longer implicitly included by bsd.own.mk. If you wish to 1620 use COMPILER_TYPE, you must now explicitly include bsd.compiler.mk 1621 as well. 1622 162320140430: 1624 The lindev device has been removed since /dev/full has been made a 1625 standard device. __FreeBSD_version has been bumped. 1626 162720140424: 1628 The knob WITHOUT_VI was added to the base system, which controls 1629 building ex(1), vi(1), etc. Older releases of FreeBSD required ex(1) 1630 in order to reorder files share/termcap and didn't build ex(1) as a 1631 build tool, so building/installing with WITH_VI is highly advised for 1632 build hosts for older releases. 1633 1634 This issue has been fixed in stable/9 and stable/10 in r277022 and 1635 r276991, respectively. 1636 163720140418: 1638 The YES_HESIOD knob has been removed. It has been obsolete for 1639 a decade. Please move to using WITH_HESIOD instead or your builds 1640 will silently lack HESIOD. 1641 164220140405: 1643 The uart(4) driver has been changed with respect to its handling 1644 of the low-level console. Previously the uart(4) driver prevented 1645 any process from changing the baudrate or the CLOCAL and HUPCL 1646 control flags. By removing the restrictions, operators can make 1647 changes to the serial console port without having to reboot. 1648 However, when getty(8) is started on the serial device that is 1649 associated with the low-level console, a misconfigured terminal 1650 line in /etc/ttys will now have a real impact. 1651 Before upgrading the kernel, make sure that /etc/ttys has the 1652 serial console device configured as 3wire without baudrate to 1653 preserve the previous behaviour. E.g: 1654 ttyu0 "/usr/libexec/getty 3wire" vt100 on secure 1655 165620140306: 1657 Support for libwrap (TCP wrappers) in rpcbind was disabled by default 1658 to improve performance. To re-enable it, if needed, run rpcbind 1659 with command line option -W. 1660 166120140226: 1662 Switched back to the GPL dtc compiler due to updates in the upstream 1663 dts files not being supported by the BSDL dtc compiler. You will need 1664 to rebuild your kernel toolchain to pick up the new compiler. Core dumps 1665 may result while building dtb files during a kernel build if you fail 1666 to do so. Set WITHOUT_GPL_DTC if you require the BSDL compiler. 1667 166820140216: 1669 Clang and llvm have been upgraded to 3.4 release. 1670 167120140216: 1672 The nve(4) driver has been removed. Please use the nfe(4) driver 1673 for NVIDIA nForce MCP Ethernet adapters instead. 1674 167520140212: 1676 An ABI incompatibility crept into the libc++ 3.4 import in r261283. 1677 This could cause certain C++ applications using shared libraries built 1678 against the previous version of libc++ to crash. The incompatibility 1679 has now been fixed, but any C++ applications or shared libraries built 1680 between r261283 and r261801 should be recompiled. 1681 168220140204: 1683 OpenSSH will now ignore errors caused by kernel lacking of Capsicum 1684 capability mode support. Please note that enabling the feature in 1685 kernel is still highly recommended. 1686 168720140131: 1688 OpenSSH is now built with sandbox support, and will use sandbox as 1689 the default privilege separation method. This requires Capsicum 1690 capability mode support in kernel. 1691 169220140128: 1693 The libelf and libdwarf libraries have been updated to newer 1694 versions from upstream. Shared library version numbers for 1695 these two libraries were bumped. Any ports or binaries 1696 requiring these two libraries should be recompiled. 1697 __FreeBSD_version is bumped to 1100006. 1698 169920140110: 1700 If a Makefile in a tests/ directory was auto-generating a Kyuafile 1701 instead of providing an explicit one, this would prevent such 1702 Makefile from providing its own Kyuafile in the future during 1703 NO_CLEAN builds. This has been fixed in the Makefiles but manual 1704 intervention is needed to clean an objdir if you use NO_CLEAN: 1705 # find /usr/obj -name Kyuafile | xargs rm -f 1706 170720131213: 1708 The behavior of gss_pseudo_random() for the krb5 mechanism 1709 has changed, for applications requesting a longer random string 1710 than produced by the underlying enctype's pseudo-random() function. 1711 In particular, the random string produced from a session key of 1712 enctype aes256-cts-hmac-sha1-96 or aes256-cts-hmac-sha1-96 will 1713 be different at the 17th octet and later, after this change. 1714 The counter used in the PRF+ construction is now encoded as a 1715 big-endian integer in accordance with RFC 4402. 1716 __FreeBSD_version is bumped to 1100004. 1717 171820131108: 1719 The WITHOUT_ATF build knob has been removed and its functionality 1720 has been subsumed into the more generic WITHOUT_TESTS. If you were 1721 using the former to disable the build of the ATF libraries, you 1722 should change your settings to use the latter. 1723 172420131025: 1725 The default version of mtree is nmtree which is obtained from 1726 NetBSD. The output is generally the same, but may vary 1727 slightly. If you found you need identical output adding 1728 "-F freebsd9" to the command line should do the trick. For the 1729 time being, the old mtree is available as fmtree. 1730 173120131014: 1732 libbsdyml has been renamed to libyaml and moved to /usr/lib/private. 1733 This will break ports-mgmt/pkg. Rebuild the port, or upgrade to pkg 1734 1.1.4_8 and verify bsdyml not linked in, before running "make 1735 delete-old-libs": 1736 # make -C /usr/ports/ports-mgmt/pkg build deinstall install clean 1737 or 1738 # pkg install pkg; ldd /usr/local/sbin/pkg | grep bsdyml 1739 174020131010: 1741 The stable/10 branch has been created in subversion from head 1742 revision r256279. 1743 1744COMMON ITEMS: 1745 1746 General Notes 1747 ------------- 1748 Avoid using make -j when upgrading. While generally safe, there are 1749 sometimes problems using -j to upgrade. If your upgrade fails with 1750 -j, please try again without -j. From time to time in the past there 1751 have been problems using -j with buildworld and/or installworld. This 1752 is especially true when upgrading between "distant" versions (eg one 1753 that cross a major release boundary or several minor releases, or when 1754 several months have passed on the -current branch). 1755 1756 Sometimes, obscure build problems are the result of environment 1757 poisoning. This can happen because the make utility reads its 1758 environment when searching for values for global variables. To run 1759 your build attempts in an "environmental clean room", prefix all make 1760 commands with 'env -i '. See the env(1) manual page for more details. 1761 1762 When upgrading from one major version to another it is generally best to 1763 upgrade to the latest code in the currently installed branch first, then 1764 do an upgrade to the new branch. This is the best-tested upgrade path, 1765 and has the highest probability of being successful. Please try this 1766 approach if you encounter problems with a major version upgrade. Since 1767 the stable 4.x branch point, one has generally been able to upgrade from 1768 anywhere in the most recent stable branch to head / current (or even the 1769 last couple of stable branches). See the top of this file when there's 1770 an exception. 1771 1772 When upgrading a live system, having a root shell around before 1773 installing anything can help undo problems. Not having a root shell 1774 around can lead to problems if pam has changed too much from your 1775 starting point to allow continued authentication after the upgrade. 1776 1777 This file should be read as a log of events. When a later event changes 1778 information of a prior event, the prior event should not be deleted. 1779 Instead, a pointer to the entry with the new information should be 1780 placed in the old entry. Readers of this file should also sanity check 1781 older entries before relying on them blindly. Authors of new entries 1782 should write them with this in mind. 1783 1784 ZFS notes 1785 --------- 1786 When upgrading the boot ZFS pool to a new version, always follow 1787 these two steps: 1788 1789 1.) recompile and reinstall the ZFS boot loader and boot block 1790 (this is part of "make buildworld" and "make installworld") 1791 1792 2.) update the ZFS boot block on your boot drive 1793 1794 The following example updates the ZFS boot block on the first 1795 partition (freebsd-boot) of a GPT partitioned drive ada0: 1796 "gpart bootcode -p /boot/gptzfsboot -i 1 ada0" 1797 1798 Non-boot pools do not need these updates. 1799 1800 To build a kernel 1801 ----------------- 1802 If you are updating from a prior version of FreeBSD (even one just 1803 a few days old), you should follow this procedure. It is the most 1804 failsafe as it uses a /usr/obj tree with a fresh mini-buildworld, 1805 1806 make kernel-toolchain 1807 make -DALWAYS_CHECK_MAKE buildkernel KERNCONF=YOUR_KERNEL_HERE 1808 make -DALWAYS_CHECK_MAKE installkernel KERNCONF=YOUR_KERNEL_HERE 1809 1810 To test a kernel once 1811 --------------------- 1812 If you just want to boot a kernel once (because you are not sure 1813 if it works, or if you want to boot a known bad kernel to provide 1814 debugging information) run 1815 make installkernel KERNCONF=YOUR_KERNEL_HERE KODIR=/boot/testkernel 1816 nextboot -k testkernel 1817 1818 To rebuild everything and install it on the current system. 1819 ----------------------------------------------------------- 1820 # Note: sometimes if you are running current you gotta do more than 1821 # is listed here if you are upgrading from a really old current. 1822 1823 <make sure you have good level 0 dumps> 1824 make buildworld 1825 make buildkernel KERNCONF=YOUR_KERNEL_HERE 1826 make installkernel KERNCONF=YOUR_KERNEL_HERE 1827 [1] 1828 <reboot in single user> [3] 1829 mergemaster -Fp [5] 1830 make installworld 1831 mergemaster -Fi [4] 1832 make delete-old [6] 1833 <reboot> 1834 1835 To cross-install current onto a separate partition 1836 -------------------------------------------------- 1837 # In this approach we use a separate partition to hold 1838 # current's root, 'usr', and 'var' directories. A partition 1839 # holding "/", "/usr" and "/var" should be about 2GB in 1840 # size. 1841 1842 <make sure you have good level 0 dumps> 1843 <boot into -stable> 1844 make buildworld 1845 make buildkernel KERNCONF=YOUR_KERNEL_HERE 1846 <maybe newfs current's root partition> 1847 <mount current's root partition on directory ${CURRENT_ROOT}> 1848 make installworld DESTDIR=${CURRENT_ROOT} -DDB_FROM_SRC 1849 make distribution DESTDIR=${CURRENT_ROOT} # if newfs'd 1850 make installkernel KERNCONF=YOUR_KERNEL_HERE DESTDIR=${CURRENT_ROOT} 1851 cp /etc/fstab ${CURRENT_ROOT}/etc/fstab # if newfs'd 1852 <edit ${CURRENT_ROOT}/etc/fstab to mount "/" from the correct partition> 1853 <reboot into current> 1854 <do a "native" rebuild/install as described in the previous section> 1855 <maybe install compatibility libraries from ports/misc/compat*> 1856 <reboot> 1857 1858 1859 To upgrade in-place from stable to current 1860 ---------------------------------------------- 1861 <make sure you have good level 0 dumps> 1862 make buildworld [9] 1863 make buildkernel KERNCONF=YOUR_KERNEL_HERE [8] 1864 make installkernel KERNCONF=YOUR_KERNEL_HERE 1865 [1] 1866 <reboot in single user> [3] 1867 mergemaster -Fp [5] 1868 make installworld 1869 mergemaster -Fi [4] 1870 make delete-old [6] 1871 <reboot> 1872 1873 Make sure that you've read the UPDATING file to understand the 1874 tweaks to various things you need. At this point in the life 1875 cycle of current, things change often and you are on your own 1876 to cope. The defaults can also change, so please read ALL of 1877 the UPDATING entries. 1878 1879 Also, if you are tracking -current, you must be subscribed to 1880 freebsd-current@freebsd.org. Make sure that before you update 1881 your sources that you have read and understood all the recent 1882 messages there. If in doubt, please track -stable which has 1883 much fewer pitfalls. 1884 1885 [1] If you have third party modules, such as vmware, you 1886 should disable them at this point so they don't crash your 1887 system on reboot. 1888 1889 [3] From the bootblocks, boot -s, and then do 1890 fsck -p 1891 mount -u / 1892 mount -a 1893 cd src 1894 adjkerntz -i # if CMOS is wall time 1895 Also, when doing a major release upgrade, it is required that 1896 you boot into single user mode to do the installworld. 1897 1898 [4] Note: This step is non-optional. Failure to do this step 1899 can result in a significant reduction in the functionality of the 1900 system. Attempting to do it by hand is not recommended and those 1901 that pursue this avenue should read this file carefully, as well 1902 as the archives of freebsd-current and freebsd-hackers mailing lists 1903 for potential gotchas. The -U option is also useful to consider. 1904 See mergemaster(8) for more information. 1905 1906 [5] Usually this step is a no-op. However, from time to time 1907 you may need to do this if you get unknown user in the following 1908 step. It never hurts to do it all the time. You may need to 1909 install a new mergemaster (cd src/usr.sbin/mergemaster && make 1910 install) after the buildworld before this step if you last updated 1911 from current before 20130425 or from -stable before 20130430. 1912 1913 [6] This only deletes old files and directories. Old libraries 1914 can be deleted by "make delete-old-libs", but you have to make 1915 sure that no program is using those libraries anymore. 1916 1917 [8] The new kernel must be able to run existing binaries used by 1918 an installworld. When upgrading across major versions, the new 1919 kernel's configuration must include the correct COMPAT_FREEBSD<n> 1920 option for existing binaries (e.g. COMPAT_FREEBSD11 to run 11.x 1921 binaries). Failure to do so may leave you with a system that is 1922 hard to boot to recover. A GENERIC kernel will include suitable 1923 compatibility options to run binaries from older branches. 1924 1925 Make sure that you merge any new devices from GENERIC since the 1926 last time you updated your kernel config file. 1927 1928 [9] If CPUTYPE is defined in your /etc/make.conf, make sure to use the 1929 "?=" instead of the "=" assignment operator, so that buildworld can 1930 override the CPUTYPE if it needs to. 1931 1932 MAKEOBJDIRPREFIX must be defined in an environment variable, and 1933 not on the command line, or in /etc/make.conf. buildworld will 1934 warn if it is improperly defined. 1935FORMAT: 1936 1937This file contains a list, in reverse chronological order, of major 1938breakages in tracking -current. It is not guaranteed to be a complete 1939list of such breakages, and only contains entries since September 23, 2011. 1940If you need to see UPDATING entries from before that date, you will need 1941to fetch an UPDATING file from an older FreeBSD release. 1942 1943Copyright information: 1944 1945Copyright 1998-2009 M.
