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 3420190513: 35 User-wired pages now have their own counter, 36 vm.stats.vm.v_user_wire_count. The vm.max_wired sysctl was renamed 37 to vm.max_user_wired and changed from an unsigned int to an unsigned 38 long. bhyve VMs wired with the -S are now subject to the user 39 wiring limit; the vm.max_user_wired sysctl may need to be tuned to 40 avoid running into the limit. 41 4220190507: 43 The IPSEC option has been removed from GENERIC. Users requiring 44 ipsec(4) must now load the ipsec(4) kernel module. 45 4620190507: 47 The tap(4) driver has been folded into tun(4), and the module has been 48 renamed to tuntap. You should update any kld_load="if_tap" or 49 kld_load="if_tun" entries in /etc/rc.conf, if_tap_load="YES" or 50 if_tun_load="YES" entries in /boot/loader.conf to load the if_tuntap 51 module instead, and "device tap" or "device tun" entries in kernel 52 config files to select the tuntap device instead. 53 5420190418: 55 The following knobs have been added related to tradeoffs between 56 safe use of the random device and availability in the absence of 57 entropy: 58 59 kern.random.initial_seeding.bypass_before_seeding: tunable; set 60 non-zero to bypass the random device prior to seeding, or zero to 61 block random requests until the random device is initially seeded. 62 For now, set to 1 (unsafe) by default to restore pre-r346250 boot 63 availability properties. 64 65 kern.random.initial_seeding.read_random_bypassed_before_seeding: 66 read-only diagnostic sysctl that is set when bypass is enabled and 67 read_random(9) is bypassed, to enable programmatic handling of this 68 initial condition, if desired. 69 70 kern.random.initial_seeding.arc4random_bypassed_before_seeding: 71 Similar to the above, but for for arc4random(9) initial seeding. 72 73 kern.random.initial_seeding.disable_bypass_warnings: tunable; set 74 non-zero to disable warnings in dmesg when the same conditions are 75 met as for the diagnostic sysctls above. Defaults to zero, i.e., 76 produce warnings in dmesg when the conditions are met. 77 7820190416: 79 The loadable random module KPI has changed; the random_infra_init() 80 routine now requires a 3rd function pointer for a bool (*)(void) 81 method that returns true if the random device is seeded (and 82 therefore unblocked). 83 8420190404: 85 r345895 reverts r320698. This implies that an nfsuserd(8) daemon 86 built from head sources between r320757 (July 6, 2017) and 87 r338192 (Aug. 22, 2018) will not work unless the "-use-udpsock" 88 is added to the command line. 89 nfsuserd daemons built from head sources that are post-r338192 are 90 not affected and should continue to work. 91 9220190320: 93 The fuse(4) module has been renamed to fusefs(4) for consistency with 94 other filesystems. You should update any kld_load="fuse" entries in 95 /etc/rc.conf, fuse_load="YES" entries in /boot/loader.conf, and 96 "options FUSE" entries in kernel config files. 97 9820190304: 99 Clang, llvm, lld, lldb, compiler-rt and libc++ have been upgraded to 100 8.0.0. Please see the 20141231 entry below for information about 101 prerequisites and upgrading, if you are not already using clang 3.5.0 102 or higher. 103 10420190226: 105 geom_uzip(4) depends on the new module xz. If geom_uzip is statically 106 compiled into your custom kernel, add 'device xz' statement to the 107 kernel config. 108 10920190219: 110 drm and drm2 have been removed from the tree. Please see 111 https://wiki.freebsd.org/Graphics for the latest information on 112 migrating to the drm ports. 113 11420190131: 115 Iflib is no longer unconditionally compiled into the kernel. Drivers 116 using iflib and statically compiled into the kernel, now require 117 the 'device iflib' config option. For the same drivers loaded as 118 modules on kernels not having 'device iflib', the iflib.ko module 119 is loaded automatically. 120 12120190125: 122 The IEEE80211_AMPDU_AGE and AH_SUPPORT_AR5416 kernel configuration 123 options no longer exist since r343219 and r343427 respectively; 124 nothing uses them, so they should be just removed from custom 125 kernel config files. 126 12720181230: 128 r342635 changes the way efibootmgr(8) works by requiring users to add 129 the -b (bootnum) parameter for commands where the bootnum was previously 130 specified with each option. For example 'efibootmgr -B 0001' is now 131 'efibootmgr -B -b 0001'. 132 13320181220: 134 r342286 modifies the NFSv4 server so that it obeys vfs.nfsd.nfs_privport 135 in the same as it is applied to NFSv2 and 3. This implies that NFSv4 136 servers that have vfs.nfsd.nfs_privport set will only allow mounts 137 from clients using a reserved port#. Since both the FreeBSD and Linux 138 NFSv4 clients use reserved port#s by default, this should not affect 139 most NFSv4 mounts. 140 14120181219: 142 The XLP config has been removed. We can't support 64-bit atomics in this 143 kernel because it is running in 32-bit mode. XLP users must transition 144 to running a 64-bit kernel (XLP64 or XLPN32). 145 146 The mips GXEMUL support has been removed from FreeBSD. MALTA* + qemu is 147 the preferred emulator today and we don't need two different ones. 148 149 The old sibyte / swarm / Broadcom BCM1250 support has been 150 removed from the mips port. 151 15220181211: 153 Clang, llvm, lld, lldb, compiler-rt and libc++ have been upgraded to 154 7.0.1. Please see the 20141231 entry below for information about 155 prerequisites and upgrading, if you are not already using clang 3.5.0 156 or higher. 157 15820181211: 159 Remove the timed and netdate programs from the base tree. Setting 160 the time with these daemons has been obsolete for over a decade. 161 16220181126: 163 On amd64, arm64 and armv7 (architectures that install LLVM's ld.lld 164 linker as /usr/bin/ld) GNU ld is no longer installed as ld.bfd, as 165 it produces broken binaries when ifuncs are in use. Users needing 166 GNU ld should install the binutils port or package. 167 16820181123: 169 The BSD crtbegin and crtend code has been enabled by default. It has 170 had extensive testing on amd64, arm64, and i386. It can be disabled 171 by building a world with -DWITHOUT_BSD_CRTBEGIN. 172 17320181115: 174 The set of CTM commands (ctm, ctm_smail, ctm_rmail, ctm_dequeue) 175 has been converted to a port (misc/ctm) and will be removed from 176 FreeBSD-13. It is available as a package (ctm) for all supported 177 FreeBSD versions. 178 17920181110: 180 The default newsyslog.conf(5) file has been changed to only include 181 files in /etc/newsyslog.conf.d/ and /usr/local/etc/newsyslog.conf.d/ if 182 the filenames end in '.conf' and do not begin with a '.'. 183 184 You should check the configuration files in these two directories match 185 this naming convention. You can verify which configuration files are 186 being included using the command: 187 $ newsyslog -Nrv 188 18920181015: 190 Ports for the DRM modules have been simplified. Now, amd64 users should 191 just install the drm-kmod port. All others should install 192 drm-legacy-kmod. 193 194 Graphics hardware that's newer than about 2010 usually works with 195 drm-kmod. For hardware older than 2013, however, some users will need 196 to use drm-legacy-kmod if drm-kmod doesn't work for them. Hardware older 197 than 2008 usually only works in drm-legacy-kmod. The graphics team can 198 only commit to hardware made since 2013 due to the complexity of the 199 market and difficulty to test all the older cards effectively. If you 200 have hardware supported by drm-kmod, you are strongly encouraged to use 201 that as you will get better support. 202 203 Other than KPI chasing, drm-legacy-kmod will not be updated. As outlined 204 elsewhere, the drm and drm2 modules will be eliminated from the src base 205 soon (with a limited exception for arm). Please update to the package 206 asap and report any issues to x11@freebsd.org. 207 208 Generally, anybody using the drm*-kmod packages should add 209 WITHOUT_DRM_MODULE=t and WITHOUT_DRM2_MODULE=t to avoid nasty 210 cross-threading surprises, especially with automatic driver 211 loading from X11 startup. These will become the defaults in 13-current 212 shortly. 213 21420181012: 215 The ixlv(4) driver has been renamed to iavf(4). As a consequence, 216 custom kernel and module loading configuration files must be updated 217 accordingly. Moreover, interfaces previous presented as ixlvN to the 218 system are now exposed as iavfN and network configuration files must 219 be adjusted as necessary. 220 22120181009: 222 OpenSSL has been updated to version 1.1.1. This update included 223 additional various API changes throughout the base system. It is 224 important to rebuild third-party software after upgrading. The value 225 of __FreeBSD_version has been bumped accordingly. 226 22720181006: 228 The legacy DRM modules and drivers have now been added to the loader's 229 module blacklist, in favor of loading them with kld_list in rc.conf(5). 230 The module blacklist may be overridden with the loader.conf(5) 231 'module_blacklist' variable, but loading them via rc.conf(5) is strongly 232 encouraged. 233 23420181002: 235 The cam(4) based nda(4) driver will be used over nvd(4) by default on 236 powerpc64. You may set 'options NVME_USE_NVD=1' in your kernel conf or 237 loader tunable 'hw.nvme.use_nvd=1' if you wish to use the existing 238 driver. Make sure to edit /boot/etc/kboot.conf and fstab to use the 239 nda device name. 240 24120180913: 242 Reproducible build mode is now on by default, in preparation for 243 FreeBSD 12.0. This eliminates build metadata such as the user, 244 host, and time from the kernel (and uname), unless the working tree 245 corresponds to a modified checkout from a version control system. 246 The previous behavior can be obtained by setting the /etc/src.conf 247 knob WITHOUT_REPRODUCIBLE_BUILD. 248 24920180826: 250 The Yarrow CSPRNG has been removed from the kernel as it has not been 251 supported by its designers since at least 2003. Fortuna has been the 252 default since FreeBSD-11. 253 25420180822: 255 devctl freeze/thaw have gone into the tree, the rc scripts have been 256 updated to use them and devmatch has been changed. You should update 257 kernel, userland and rc scripts all at the same time. 258 25920180818: 260 The default interpreter has been switched from 4th to Lua. 261 LOADER_DEFAULT_INTERP, documented in build(7), will override the default 262 interpreter. If you have custom FORTH code you will need to set 263 LOADER_DEFAULT_INTERP=4th (valid values are 4th, lua or simp) in 264 src.conf for the build. This will create default hard links between 265 loader and loader_4th instead of loader and loader_lua, the new default. 266 If you are using UEFI it will create the proper hard link to loader.efi. 267 268 bhyve uses userboot.so. It remains 4th-only until some issues are solved 269 regarding coexisting with multiple versions of FreeBSD are resolved. 270 27120180815: 272 ls(1) now respects the COLORTERM environment variable used in other 273 systems and software to indicate that a colored terminal is both 274 supported and desired. If ls(1) is suddenly emitting colors, they may 275 be disabled again by either removing the unwanted COLORTERM from your 276 environment, or using `ls --color=never`. The ls(1) specific CLICOLOR 277 may not be observed in a future release. 278 27920180808: 280 The default pager for most commands has been changed to "less". To 281 restore the old behavior, set PAGER="more" and MANPAGER="more -s" in 282 your environment. 283 28420180731: 285 The jedec_ts(4) driver has been removed. A superset of its functionality 286 is available in the jedec_dimm(4) driver, and the manpage for that 287 driver includes migration instructions. If you have "device jedec_ts" 288 in your kernel configuration file, it must be removed. 289 29020180730: 291 amd64/GENERIC now has EFI runtime services, EFIRT, enabled by default. 292 This should have no effect if the kernel is booted via BIOS/legacy boot. 293 EFIRT may be disabled via a loader tunable, efi.rt.disabled, if a system 294 has a buggy firmware that prevents a successful boot due to use of 295 runtime services. 296 29720180727: 298 Atmel AT91RM9200 and AT91SAM9, Cavium CNS 11xx and XScale 299 support has been removed from the tree. These ports were 300 obsolete and/or known to be broken for many years. 301 30220180723: 303 loader.efi has been augmented to participate more fully in the 304 UEFI boot manager protocol. loader.efi will now look at the 305 BootXXXX environment variable to determine if a specific kernel 306 or root partition was specified. XXXX is derived from BootCurrent. 307 efibootmgr(8) manages these standard UEFI variables. 308 30920180720: 310 zfsloader's functionality has now been folded into loader. 311 zfsloader is no longer necessary once you've updated your 312 boot blocks. For a transition period, we will install a 313 hardlink for zfsloader to loader to allow a smooth transition 314 until the boot blocks can be updated (hard link because old 315 zfs boot blocks don't understand symlinks). 316 31720180719: 318 ARM64 now have efifb support, if you want to have serial console 319 on your arm64 board when an screen is connected and the bootloader 320 setup a frame buffer for us to use, just add : 321 boot_serial=YES 322 boot_multicons=YES 323 in /boot/loader.conf 324 For Raspberry Pi 3 (RPI) users, this is needed even if you don't have 325 an screen connected as the firmware will setup a frame buffer are that 326 u-boot will expose as an EFI frame buffer. 327 32820180719: 329 New uid:gid added, ntpd:ntpd (123:123). Be sure to run mergemaster 330 or take steps to update /etc/passwd before doing installworld on 331 existing systems. Do not skip the "mergemaster -Fp" step before 332 installworld, as described in the update procedures near the bottom 333 of this document. Also, rc.d/ntpd now starts ntpd(8) as user ntpd 334 if the new mac_ntpd(4) policy is available, unless ntpd_flags or 335 the ntp config file contain options that change file/dir locations. 336 When such options (e.g., "statsdir" or "crypto") are used, ntpd can 337 still be run as non-root by setting ntpd_user=ntpd in rc.conf, after 338 taking steps to ensure that all required files/dirs are accessible 339 by the ntpd user. 340 34120180717: 342 Big endian arm support has been removed. 343 34420180711: 345 The static environment setup in kernel configs is no longer mutually 346 exclusive with the loader(8) environment by default. In order to 347 restore the previous default behavior of disabling the loader(8) 348 environment if a static environment is present, you must specify 349 loader_env.disabled=1 in the static environment. 350 35120180705: 352 The ABI of syscalls used by management tools like sockstat and 353 netstat has been broken to allow 32-bit binaries to work on 354 64-bit kernels without modification. These programs will need 355 to match the kernel in order to function. External programs may 356 require minor modifications to accommodate a change of type in 357 structures from pointers to 64-bit virtual addresses. 358 35920180702: 360 On i386 and amd64 atomics are now inlined. Out of tree modules using 361 atomics will need to be rebuilt. 362 36320180701: 364 The '%I' format in the kern.corefile sysctl limits the number of 365 core files that a process can generate to the number stored in the 366 debug.ncores sysctl. The '%I' format is replaced by the single digit 367 index. Previously, if all indexes were taken the kernel would overwrite 368 only a core file with the highest index in a filename. 369 Currently the system will create a new core file if there is a free 370 index or if all slots are taken it will overwrite the oldest one. 371 37220180630: 373 Clang, llvm, lld, lldb, compiler-rt and libc++ have been upgraded to 374 6.0.1. Please see the 20141231 entry below for information about 375 prerequisites and upgrading, if you are not already using clang 3.5.0 376 or higher. 377 37820180628: 379 r335753 introduced a new quoting method. However, etc/devd/devmatch.conf 380 needed to be changed to work with it. This change was made with r335763 381 and requires a mergemaster / etcupdate / etc to update the installed 382 file. 383 38420180612: 385 r334930 changed the interface between the NFS modules, so they all 386 need to be rebuilt. r335018 did a __FreeBSD_version bump for this. 387 38820180530: 389 As of r334391 lld is the default amd64 system linker; it is installed 390 as /usr/bin/ld. Kernel build workarounds (see 20180510 entry) are no 391 longer necessary. 392 39320180530: 394 The kernel / userland interface for devinfo changed, so you'll 395 need a new kernel and userland as a pair for it to work (rebuilding 396 lib/libdevinfo is all that's required). devinfo and devmatch will 397 not work, but everything else will when there's a mismatch. 398 39920180523: 400 The on-disk format for hwpmc callchain records has changed to include 401 threadid corresponding to a given record. This changes the field offsets 402 and thus requires that libpmcstat be rebuilt before using a kernel 403 later than r334108. 404 40520180517: 406 The vxge(4) driver has been removed. This driver was introduced into 407 HEAD one week before the Exar left the Ethernet market and is not 408 known to be used. If you have device vxge in your kernel config file 409 it must be removed. 410 41120180510: 412 The amd64 kernel now requires a ld that supports ifunc to produce a 413 working kernel, either lld or a newer binutils. lld is built by default 414 on amd64, and the 'buildkernel' target uses it automatically. However, 415 it is not the default linker, so building the kernel the traditional 416 way requires LD=ld.lld on the command line (or LD=/usr/local/bin/ld for 417 binutils port/package). lld will soon be default, and this requirement 418 will go away. 419 420 NOTE: As of r334391 lld is the default system linker on amd64, and no 421 workaround is necessary. 422 42320180508: 424 The nxge(4) driver has been removed. This driver was for PCI-X 10g 425 cards made by s2io/Neterion. The company was acquired by Exar and 426 no longer sells or supports Ethernet products. If you have device 427 nxge in your kernel config file it must be removed. 428 42920180504: 430 The tz database (tzdb) has been updated to 2018e. This version more 431 correctly models time stamps in time zones with negative DST such as 432 Europe/Dublin (from 1971 on), Europe/Prague (1946/7), and 433 Africa/Windhoek (1994/2017). This does not affect the UT offsets, only 434 time zone abbreviations and the tm_isdst flag. 435 43620180502: 437 The ixgb(4) driver has been removed. This driver was for an early and 438 uncommon legacy PCI 10GbE for a single ASIC, Intel 82597EX. Intel 439 quickly shifted to the long lived ixgbe family. If you have device 440 ixgb in your kernel config file it must be removed. 441 44220180501: 443 The lmc(4) driver has been removed. This was a WAN interface 444 card that was already reportedly rare in 2003, and had an ambiguous 445 license. If you have device lmc in your kernel config file it must 446 be removed. 447 44820180413: 449 Support for Arcnet networks has been removed. If you have device 450 arcnet or device cm in your kernel config file they must be 451 removed. 452 45320180411: 454 Support for FDDI networks has been removed. If you have device 455 fddi or device fpa in your kernel config file they must be 456 removed. 457 45820180406: 459 In addition to supporting RFC 3164 formatted messages, the 460 syslogd(8) service is now capable of parsing RFC 5424 formatted 461 log messages. The main benefit of using RFC 5424 is that clients 462 may now send log messages with timestamps containing year numbers, 463 microseconds and time zone offsets. 464 465 Similarly, the syslog(3) C library function has been altered to 466 send RFC 5424 formatted messages to the local system logging 467 daemon. On systems using syslogd(8), this change should have no 468 negative impact, as long as syslogd(8) and the C library are 469 updated at the same time. On systems using a different system 470 logging daemon, it may be necessary to make configuration 471 adjustments, depending on the software used. 472 473 When using syslog-ng, add the 'syslog-protocol' flag to local 474 input sources to enable parsing of RFC 5424 formatted messages: 475 476 source src { 477 unix-dgram("/var/run/log" flags(syslog-protocol)); 478 } 479 480 When using rsyslog, disable the 'SysSock.UseSpecialParser' option 481 of the 'imuxsock' module to let messages be processed by the 482 regular RFC 3164/5424 parsing pipeline: 483 484 module(load="imuxsock" SysSock.UseSpecialParser="off") 485 486 Do note that these changes only affect communication between local 487 applications and syslogd(8). The format that syslogd(8) uses to 488 store messages on disk or forward messages to other systems 489 remains unchanged. syslogd(8) still uses RFC 3164 for these 490 purposes. Options to customize this behaviour will be added in the 491 future. Utilities that process log files stored in /var/log are 492 thus expected to continue to function as before. 493 494 __FreeBSD_version has been incremented to 1200061 to denote this 495 change. 496 49720180328: 498 Support for token ring networks has been removed. If you 499 have "device token" in your kernel config you should remove 500 it. No device drivers supported token ring. 501 50220180323: 503 makefs was modified to be able to tag ISO9660 El Torito boot catalog 504 entries as EFI instead of overloading the i386 tag as done previously. 505 The amd64 mkisoimages.sh script used to build amd64 ISO images for 506 release was updated to use this. This may mean that makefs must be 507 updated before "make cdrom" can be run in the release directory. This 508 should be as simple as: 509 510 $ cd $SRCDIR/usr.sbin/makefs 511 $ make depend all install 512 51320180212: 514 FreeBSD boot loader enhanced with Lua scripting. It's purely opt-in for 515 now by building WITH_LOADER_LUA and WITHOUT_FORTH in /etc/src.conf. 516 Co-existence for the transition period will come shortly. Booting is a 517 complex environment and test coverage for Lua-enabled loaders has been 518 thin, so it would be prudent to assume it might not work and make 519 provisions for backup boot methods. 520 52120180211: 522 devmatch functionality has been turned on in devd. It will automatically 523 load drivers for unattached devices. This may cause unexpected drivers 524 to be loaded. Please report any problems to current@ and 525 imp@freebsd.org. 526 52720180114: 528 Clang, llvm, lld, lldb, compiler-rt and libc++ have been upgraded to 529 6.0.0. Please see the 20141231 entry below for information about 530 prerequisites and upgrading, if you are not already using clang 3.5.0 531 or higher. 532 53320180110: 534 LLVM's lld linker is now used as the FreeBSD/amd64 bootstrap linker. 535 This means it is used to link the kernel and userland libraries and 536 executables, but is not yet installed as /usr/bin/ld by default. 537 538 To revert to ld.bfd as the bootstrap linker, in /etc/src.conf set 539 WITHOUT_LLD_BOOTSTRAP=yes 540 54120180110: 542 On i386, pmtimer has been removed. Its functionality has been folded 543 into apm. It was a no-op on ACPI in current for a while now (but was 544 still needed on i386 in FreeBSD 11 and earlier). Users may need to 545 remove it from kernel config files. 546 54720180104: 548 The use of RSS hash from the network card aka flowid has been 549 disabled by default for lagg(4) as it's currently incompatible with 550 the lacp and loadbalance protocols. 551 552 This can be re-enabled by setting the following in loader.conf: 553 net.link.lagg.default_use_flowid="1" 554 55520180102: 556 The SW_WATCHDOG option is no longer necessary to enable the 557 hardclock-based software watchdog if no hardware watchdog is 558 configured. As before, SW_WATCHDOG will cause the software 559 watchdog to be enabled even if a hardware watchdog is configured. 560 56120171215: 562 r326887 fixes the issue described in the 20171214 UPDATING entry. 563 r326888 flips the switch back to building GELI support always. 564 56520171214: 566 r362593 broke ZFS + GELI support for reasons unknown. However, 567 it also broke ZFS support generally, so GELI has been turned off 568 by default as the lesser evil in r326857. If you boot off ZFS and/or 569 GELI, it might not be a good time to update. 570 57120171125: 572 PowerPC users must update loader(8) by rebuilding world before 573 installing a new kernel, as the protocol connecting them has 574 changed. Without the update, loader metadata will not be passed 575 successfully to the kernel and users will have to enter their 576 root partition at the kernel mountroot prompt to continue booting. 577 Newer versions of loader can boot old kernels without issue. 578 57920171110: 580 The LOADER_FIREWIRE_SUPPORT build variable as been renamed to 581 WITH/OUT_LOADER_FIREWIRE. LOADER_{NO_,}GELI_SUPPORT has been renamed 582 to WITH/OUT_LOADER_GELI. 583 58420171106: 585 The naive and non-compliant support of posix_fallocate(2) in ZFS 586 has been removed as of r325320. The system call now returns EINVAL 587 when used on a ZFS file. Although the new behavior complies with the 588 standard, some consumers are not prepared to cope with it. 589 One known victim is lld prior to r325420. 590 59120171102: 592 Building in a FreeBSD src checkout will automatically create object 593 directories now rather than store files in the current directory if 594 'make obj' was not ran. Calling 'make obj' is no longer necessary. 595 This feature can be disabled by setting WITHOUT_AUTO_OBJ=yes in 596 /etc/src-env.conf (not /etc/src.conf), or passing the option in the 597 environment. 598 59920171101: 600 The default MAKEOBJDIR has changed from /usr/obj/<srcdir> for native 601 builds, and /usr/obj/<arch>/<srcdir> for cross-builds, to a unified 602 /usr/obj/<srcdir>/<arch>. This behavior can be changed to the old 603 format by setting WITHOUT_UNIFIED_OBJDIR=yes in /etc/src-env.conf, 604 the environment, or with -DWITHOUT_UNIFIED_OBJDIR when building. 605 The UNIFIED_OBJDIR option is a transitional feature that will be 606 removed for 12.0 release; please migrate to the new format for any 607 tools by looking up the OBJDIR used by 'make -V .OBJDIR' means rather 608 than hardcoding paths. 609 61020171028: 611 The native-xtools target no longer installs the files by default to the 612 OBJDIR. Use the native-xtools-install target with a DESTDIR to install 613 to ${DESTDIR}/${NXTP} where NXTP defaults to /nxb-bin. 614 61520171021: 616 As part of the boot loader infrastructure cleanup, LOADER_*_SUPPORT 617 options are changing from controlling the build if defined / undefined 618 to controlling the build with explicit 'yes' or 'no' values. They will 619 shift to WITH/WITHOUT options to match other options in the system. 620 62120171010: 622 libstand has turned into a private library for sys/boot use only. 623 It is no longer supported as a public interface outside of sys/boot. 624 62520171005: 626 The arm port has split armv6 into armv6 and armv7. armv7 is now 627 a valid TARGET_ARCH/MACHINE_ARCH setting. If you have an armv7 system 628 and are running a kernel from before r324363, you will need to add 629 MACHINE_ARCH=armv7 to 'make buildworld' to do a native build. 630 63120171003: 632 When building multiple kernels using KERNCONF, non-existent KERNCONF 633 files will produce an error and buildkernel will fail. Previously 634 missing KERNCONF files silently failed giving no indication as to 635 why, only to subsequently discover during installkernel that the 636 desired kernel was never built in the first place. 637 63820170912: 639 The default serial number format for CTL LUNs has changed. This will 640 affect users who use /dev/diskid/* device nodes, or whose FibreChannel 641 or iSCSI clients care about their LUNs' serial numbers. Users who 642 require serial number stability should hardcode serial numbers in 643 /etc/ctl.conf . 644 64520170912: 646 For 32-bit arm compiled for hard-float support, soft-floating point 647 binaries now always get their shared libraries from 648 LD_SOFT_LIBRARY_PATH (in the past, this was only used if 649 /usr/libsoft also existed). Only users with a hard-float ld.so, but 650 soft-float everything else should be affected. 651 65220170826: 653 The geli password typed at boot is now hidden. To restore the previous 654 behavior, see geli(8) for configuration options. 655 65620170825: 657 Move PMTUD blackhole counters to TCPSTATS and remove them from bare 658 sysctl values. Minor nit, but requires a rebuild of both world/kernel 659 to complete. 660 66120170814: 662 "make check" behavior (made in ^/head@r295380) has been changed to 663 execute from a limited sandbox, as opposed to executing from 664 ${TESTSDIR}. 665 666 Behavioral changes: 667 - The "beforecheck" and "aftercheck" targets are now specified. 668 - ${CHECKDIR} (added in commit noted above) has been removed. 669 - Legacy behavior can be enabled by setting 670 WITHOUT_MAKE_CHECK_USE_SANDBOX in src.conf(5) or the environment. 671 672 If the limited sandbox mode is enabled, "make check" will execute 673 "make distribution", then install, execute the tests, and clean up the 674 sandbox if successful. 675 676 The "make distribution" and "make install" targets are typically run as 677 root to set appropriate permissions and ownership at installation time. 678 The end-user should set "WITH_INSTALL_AS_USER" in src.conf(5) or the 679 environment if executing "make check" with limited sandbox mode using 680 an unprivileged user. 681 68220170808: 683 Since the switch to GPT disk labels, fsck for UFS/FFS has been 684 unable to automatically find alternate superblocks. As of r322297, 685 the information needed to find alternate superblocks has been 686 moved to the end of the area reserved for the boot block. 687 Filesystems created with a newfs of this vintage or later 688 will create the recovery information. If you have a filesystem 689 created prior to this change and wish to have a recovery block 690 created for your filesystem, you can do so by running fsck in 691 foreground mode (i.e., do not use the -p or -y options). As it 692 starts, fsck will ask ``SAVE DATA TO FIND ALTERNATE SUPERBLOCKS'' 693 to which you should answer yes. 694 69520170728: 696 As of r321665, an NFSv4 server configuration that services 697 Kerberos mounts or clients that do not support the uid/gid in 698 owner/owner_group string capability, must explicitly enable 699 the nfsuserd daemon by adding nfsuserd_enable="YES" to the 700 machine's /etc/rc.conf file. 701 70220170722: 703 Clang, llvm, lldb, compiler-rt and libc++ have been upgraded to 5.0.0. 704 Please see the 20141231 entry below for information about prerequisites 705 and upgrading, if you are not already using clang 3.5.0 or higher. 706 70720170701: 708 WITHOUT_RCMDS is now the default. Set WITH_RCMDS if you need the 709 r-commands (rlogin, rsh, etc.) to be built with the base system. 710 71120170625: 712 The FreeBSD/powerpc platform now uses a 64-bit type for time_t. This is 713 a very major ABI incompatible change, so users of FreeBSD/powerpc must 714 be careful when performing source upgrades. It is best to run 715 'make installworld' from an alternate root system, either a live 716 CD/memory stick, or a temporary root partition. Additionally, all ports 717 must be recompiled. powerpc64 is largely unaffected, except in the case 718 of 32-bit compatibility. All 32-bit binaries will be affected. 719 72020170623: 721 Forward compatibility for the "ino64" project have been committed. This 722 will allow most new binaries to run on older kernels in a limited 723 fashion. This prevents many of the common foot-shooting actions in the 724 upgrade as well as the limited ability to roll back the kernel across 725 the ino64 upgrade. Complicated use cases may not work properly, though 726 enough simpler ones work to allow recovery in most situations. 727 72820170620: 729 Switch back to the BSDL dtc (Device Tree Compiler). Set WITH_GPL_DTC 730 if you require the GPL compiler. 731 73220170618: 733 The internal ABI used for communication between the NFS kernel modules 734 was changed by r320085, so __FreeBSD_version was bumped to 735 ensure all the NFS related modules are updated together. 736 73720170617: 738 The ABI of struct event was changed by extending the data 739 member to 64bit and adding ext fields. For upgrade, same 740 precautions as for the entry 20170523 "ino64" must be 741 followed. 742 74320170531: 744 The GNU roff toolchain has been removed from base. To render manpages 745 which are not supported by mandoc(1), man(1) can fallback on GNU roff 746 from ports (and recommends to install it). 747 To render roff(7) documents, consider using GNU roff from ports or the 748 heirloom doctools roff toolchain from ports via pkg install groff or 749 via pkg install heirloom-doctools. 750 75120170524: 752 The ath(4) and ath_hal(4) modules now build piecemeal to allow for 753 smaller runtime footprint builds. This is useful for embedded systems 754 which only require one chipset support. 755 756 If you load it as a module, make sure this is in /boot/loader.conf: 757 758 if_ath_load="YES" 759 760 This will load the HAL, all chip/RF backends and if_ath_pci. 761 If you have if_ath_pci in /boot/loader.conf, ensure it is after 762 if_ath or it will not load any HAL chipset support. 763 764 If you want to selectively load things (eg on ye cheape ARM/MIPS 765 platforms where RAM is at a premium) you should: 766 767 * load ath_hal 768 * load the chip modules in question 769 * load ath_rate, ath_dfs 770 * load ath_main 771 * load if_ath_pci and/or if_ath_ahb depending upon your particular 772 bus bind type - this is where probe/attach is done. 773 774 For further comments/feedback, poke adrian@ . 775 77620170523: 777 The "ino64" 64-bit inode project has been committed, which extends 778 a number of types to 64 bits. Upgrading in place requires care and 779 adherence to the documented upgrade procedure. 780 781 If using a custom kernel configuration ensure that the 782 COMPAT_FREEBSD11 option is included (as during the upgrade the 783 system will be running the ino64 kernel with the existing world). 784 785 For the safest in-place upgrade begin by removing previous build 786 artifacts via "rm -rf /usr/obj/*". Then, carefully follow the full 787 procedure documented below under the heading "To rebuild everything and 788 install it on the current system." Specifically, a reboot is required 789 after installing the new kernel before installing world. While an 790 installworld normally works by accident from multiuser after rebooting 791 the proper kernel, there are many cases where this will fail across this 792 upgrade and installworld from single user is required. 793 79420170424: 795 The NATM framework including the en(4), fatm(4), hatm(4), and 796 patm(4) devices has been removed. Consumers should plan a 797 migration before the end-of-life date for FreeBSD 11. 798 79920170420: 800 GNU diff has been replaced by a BSD licensed diff. Some features of GNU 801 diff has not been implemented, if those are needed a newer version of 802 GNU diff is available via the diffutils package under the gdiff name. 803 80420170413: 805 As of r316810 for ipfilter, keep frags is no longer assumed when 806 keep state is specified in a rule. r316810 aligns ipfilter with 807 documentation in man pages separating keep frags from keep state. 808 This allows keep state to be specified without forcing keep frags 809 and allows keep frags to be specified independently of keep state. 810 To maintain previous behaviour, also specify keep frags with 811 keep state (as documented in ipf.conf.5). 812 81320170407: 814 arm64 builds now use the base system LLD 4.0.0 linker by default, 815 instead of requiring that the aarch64-binutils port or package be 816 installed. To continue using aarch64-binutils, set 817 CROSS_BINUTILS_PREFIX=/usr/local/aarch64-freebsd/bin . 818 81920170405: 820 The UDP optimization in entry 20160818 that added the sysctl 821 net.inet.udp.require_l2_bcast has been reverted. L2 broadcast 822 packets will no longer be treated as L3 broadcast packets. 823 82420170331: 825 Binds and sends to the loopback addresses, IPv6 and IPv4, will now 826 use any explicitly assigned loopback address available in the jail 827 instead of using the first assigned address of the jail. 828 82920170329: 830 The ctl.ko module no longer implements the iSCSI target frontend: 831 cfiscsi.ko does instead. 832 833 If building cfiscsi.ko as a kernel module, the module can be loaded 834 via one of the following methods: 835 - `cfiscsi_load="YES"` in loader.conf(5). 836 - Add `cfiscsi` to `$kld_list` in rc.conf(5). 837 - ctladm(8)/ctld(8), when compiled with iSCSI support 838 (`WITH_ISCSI=yes` in src.conf(5)) 839 840 Please see cfiscsi(4) for more details. 841 84220170316: 843 The mmcsd.ko module now additionally depends on geom_flashmap.ko. 844 Also, mmc.ko and mmcsd.ko need to be a matching pair built from the 845 same source (previously, the dependency of mmcsd.ko on mmc.ko was 846 missing, but mmcsd.ko now will refuse to load if it is incompatible 847 with mmc.ko). 848 84920170315: 850 The syntax of ipfw(8) named states was changed to avoid ambiguity. 851 If you have used named states in the firewall rules, you need to modify 852 them after installworld and before rebooting. Now named states must 853 be prefixed with colon. 854 85520170311: 856 The old drm (sys/dev/drm/) drivers for i915 and radeon have been 857 removed as the userland we provide cannot use them. The KMS version 858 (sys/dev/drm2) supports the same hardware. 859 86020170302: 861 Clang, llvm, lldb, compiler-rt and libc++ have been upgraded to 4.0.0. 862 Please see the 20141231 entry below for information about prerequisites 863 and upgrading, if you are not already using clang 3.5.0 or higher. 864 86520170221: 866 The code that provides support for ZFS .zfs/ directory functionality 867 has been reimplemented. It's not possible now to create a snapshot 868 by mkdir under .zfs/snapshot/. That should be the only user visible 869 change. 870 87120170216: 872 EISA bus support has been removed. The WITH_EISA option is no longer 873 valid. 874 87520170215: 876 MCA bus support has been removed. 877 87820170127: 879 The WITH_LLD_AS_LD / WITHOUT_LLD_AS_LD build knobs have been renamed 880 WITH_LLD_IS_LD / WITHOUT_LLD_IS_LD, for consistency with CLANG_IS_CC. 881 88220170112: 883 The EM_MULTIQUEUE kernel configuration option is deprecated now that 884 the em(4) driver conforms to iflib specifications. 885 88620170109: 887 The igb(4), em(4) and lem(4) ethernet drivers are now implemented via 888 IFLIB. If you have a custom kernel configuration that excludes em(4) 889 but you use igb(4), you need to re-add em(4) to your custom 890 configuration. 891 89220161217: 893 Clang, llvm, lldb, compiler-rt and libc++ have been upgraded to 3.9.1. 894 Please see the 20141231 entry below for information about prerequisites 895 and upgrading, if you are not already using clang 3.5.0 or higher. 896 89720161124: 898 Clang, llvm, lldb, compiler-rt and libc++ have been upgraded to 3.9.0. 899 Please see the 20141231 entry below for information about prerequisites 900 and upgrading, if you are not already using clang 3.5.0 or higher. 901 90220161119: 903 The layout of the pmap structure has changed for powerpc to put the pmap 904 statistics at the front for all CPU variations. libkvm(3) and all tools 905 that link against it need to be recompiled. 906 90720161030: 908 isl(4) and cyapa(4) drivers now require a new driver, 909 chromebook_platform(4), to work properly on Chromebook-class hardware. 910 On other types of hardware the drivers may need to be configured using 911 device hints. Please see the corresponding manual pages for details. 912 91320161017: 914 The urtwn(4) driver was merged into rtwn(4) and now consists of 915 rtwn(4) main module + rtwn_usb(4) and rtwn_pci(4) bus-specific 916 parts. 917 Also, firmware for RTL8188CE was renamed due to possible name 918 conflict (rtwnrtl8192cU(B) -> rtwnrtl8192cE(B)) 919 92020161015: 921 GNU rcs has been removed from base. It is available as packages: 922 - rcs: Latest GPLv3 GNU rcs version. 923 - rcs57: Copy of the latest version of GNU rcs (GPLv2) before it was 924 removed from base. 925 92620161008: 927 Use of the cc_cdg, cc_chd, cc_hd, or cc_vegas congestion control 928 modules now requires that the kernel configuration contain the 929 TCP_HHOOK option. (This option is included in the GENERIC kernel.) 930 93120161003: 932 The WITHOUT_ELFCOPY_AS_OBJCOPY src.conf(5) knob has been retired. 933 ELF Tool Chain's elfcopy is always installed as /usr/bin/objcopy. 934 93520160924: 936 Relocatable object files with the extension of .So have been renamed 937 to use an extension of .pico instead. The purpose of this change is 938 to avoid a name clash with shared libraries on case-insensitive file 939 systems. On those file systems, foo.So is the same file as foo.so. 940 94120160918: 942 GNU rcs has been turned off by default. It can (temporarily) be built 943 again by adding WITH_RCS knob in src.conf. 944 Otherwise, GNU rcs is available from packages: 945 - rcs: Latest GPLv3 GNU rcs version. 946 - rcs57: Copy of the latest version of GNU rcs (GPLv2) from base. 947 94820160918: 949 The backup_uses_rcs functionality has been removed from rc.subr. 950 95120160908: 952 The queue(3) debugging macro, QUEUE_MACRO_DEBUG, has been split into 953 two separate components, QUEUE_MACRO_DEBUG_TRACE and 954 QUEUE_MACRO_DEBUG_TRASH. Define both for the original 955 QUEUE_MACRO_DEBUG behavior. 956 95720160824: 958 r304787 changed some ioctl interfaces between the iSCSI userspace 959 programs and the kernel. ctladm, ctld, iscsictl, and iscsid must be 960 rebuilt to work with new kernels. __FreeBSD_version has been bumped 961 to 1200005. 962 96320160818: 964 The UDP receive code has been updated to only treat incoming UDP 965 packets that were addressed to an L2 broadcast address as L3 966 broadcast packets. It is not expected that this will affect any 967 standards-conforming UDP application. The new behaviour can be 968 disabled by setting the sysctl net.inet.udp.require_l2_bcast to 969 0. 970 97120160818: 972 Remove the openbsd_poll system call. 973 __FreeBSD_version has been bumped because of this. 974 97520160708: 976 The stable/11 branch has been created from head@r302406. 977 97820160622: 979 The libc stub for the pipe(2) system call has been replaced with 980 a wrapper that calls the pipe2(2) system call and the pipe(2) 981 system call is now only implemented by the kernels that include 982 "options COMPAT_FREEBSD10" in their config file (this is the 983 default). Users should ensure that this option is enabled in 984 their kernel or upgrade userspace to r302092 before upgrading their 985 kernel. 986 98720160527: 988 CAM will now strip leading spaces from SCSI disks' serial numbers. 989 This will affect users who create UFS filesystems on SCSI disks using 990 those disk's diskid device nodes. For example, if /etc/fstab 991 previously contained a line like 992 "/dev/diskid/DISK-%20%20%20%20%20%20%20ABCDEFG0123456", you should 993 change it to "/dev/diskid/DISK-ABCDEFG0123456". Users of geom 994 transforms like gmirror may also be affected. ZFS users should 995 generally be fine. 996 99720160523: 998 The bitstring(3) API has been updated with new functionality and 999 improved performance. But it is binary-incompatible with the old API. 1000 Objects built with the new headers may not be linked against objects 1001 built with the old headers. 1002 100320160520: 1004 The brk and sbrk functions have been removed from libc on arm64. 1005 Binutils from ports has been updated to not link to these 1006 functions and should be updated to the latest version before 1007 installing a new libc. 1008 100920160517: 1010 The armv6 port now defaults to hard float ABI. Limited support 1011 for running both hardfloat and soft float on the same system 1012 is available using the libraries installed with -DWITH_LIBSOFT. 1013 This has only been tested as an upgrade path for installworld 1014 and packages may fail or need manual intervention to run. New 1015 packages will be needed. 1016 1017 To update an existing self-hosted armv6hf system, you must add 1018 TARGET_ARCH=armv6 on the make command line for both the build 1019 and the install steps. 1020 102120160510: 1022 Kernel modules compiled outside of a kernel build now default to 1023 installing to /boot/modules instead of /boot/kernel. Many kernel 1024 modules built this way (such as those in ports) already overrode 1025 KMODDIR explicitly to install into /boot/modules. However, 1026 manually building and installing a module from /sys/modules will 1027 now install to /boot/modules instead of /boot/kernel. 1028 102920160414: 1030 The CAM I/O scheduler has been committed to the kernel. There should be 1031 no user visible impact. This does enable NCQ Trim on ada SSDs. While the 1032 list of known rogues that claim support for this but actually corrupt 1033 data is believed to be complete, be on the lookout for data 1034 corruption. The known rogue list is believed to be complete: 1035 1036 o Crucial MX100, M550 drives with MU01 firmware. 1037 o Micron M510 and M550 drives with MU01 firmware. 1038 o Micron M500 prior to MU07 firmware 1039 o Samsung 830, 840, and 850 all firmwares 1040 o FCCT M500 all firmwares 1041 1042 Crucial has firmware http://www.crucial.com/usa/en/support-ssd-firmware 1043 with working NCQ TRIM. For Micron branded drives, see your sales rep for 1044 updated firmware. Black listed drives will work correctly because these 1045 drives work correctly so long as no NCQ TRIMs are sent to them. Given 1046 this list is the same as found in Linux, it's believed there are no 1047 other rogues in the market place. All other models from the above 1048 vendors work. 1049 1050 To be safe, if you are at all concerned, you can quirk each of your 1051 drives to prevent NCQ from being sent by setting: 1052 kern.cam.ada.X.quirks="0x2" 1053 in loader.conf. If the drive requires the 4k sector quirk, set the 1054 quirks entry to 0x3. 1055 105620160330: 1057 The FAST_DEPEND build option has been removed and its functionality is 1058 now the one true way. The old mkdep(1) style of 'make depend' has 1059 been removed. See 20160311 for further details. 1060 106120160317: 1062 Resource range types have grown from unsigned long to uintmax_t. All 1063 drivers, and anything using libdevinfo, need to be recompiled. 1064 106520160311: 1066 WITH_FAST_DEPEND is now enabled by default for in-tree and out-of-tree 1067 builds. It no longer runs mkdep(1) during 'make depend', and the 1068 'make depend' stage can safely be skipped now as it is auto ran 1069 when building 'make all' and will generate all SRCS and DPSRCS before 1070 building anything else. Dependencies are gathered at compile time with 1071 -MF flags kept in separate .depend files per object file. Users should 1072 run 'make cleandepend' once if using -DNO_CLEAN to clean out older 1073 stale .depend files. 1074 107520160306: 1076 On amd64, clang 3.8.0 can now insert sections of type AMD64_UNWIND into 1077 kernel modules. Therefore, if you load any kernel modules at boot time, 1078 please install the boot loaders after you install the kernel, but before 1079 rebooting, e.g.: 1080 1081 make buildworld 1082 make buildkernel KERNCONF=YOUR_KERNEL_HERE 1083 make installkernel KERNCONF=YOUR_KERNEL_HERE 1084 make -C sys/boot install 1085 <reboot in single user> 1086 1087 Then follow the usual steps, described in the General Notes section, 1088 below. 1089 109020160305: 1091 Clang, llvm, lldb and compiler-rt have been upgraded to 3.8.0. Please 1092 see the 20141231 entry below for information about prerequisites and 1093 upgrading, if you are not already using clang 3.5.0 or higher. 1094 109520160301: 1096 The AIO subsystem is now a standard part of the kernel. The 1097 VFS_AIO kernel option and aio.ko kernel module have been removed. 1098 Due to stability concerns, asynchronous I/O requests are only 1099 permitted on sockets and raw disks by default. To enable 1100 asynchronous I/O requests on all file types, set the 1101 vfs.aio.enable_unsafe sysctl to a non-zero value. 1102 110320160226: 1104 The ELF object manipulation tool objcopy is now provided by the 1105 ELF Tool Chain project rather than by GNU binutils. It should be a 1106 drop-in replacement, with the addition of arm64 support. The 1107 (temporary) src.conf knob WITHOUT_ELFCOPY_AS_OBJCOPY knob may be set 1108 to obtain the GNU version if necessary. 1109 111020160129: 1111 Building ZFS pools on top of zvols is prohibited by default. That 1112 feature has never worked safely; it's always been prone to deadlocks. 1113 Using a zvol as the backing store for a VM guest's virtual disk will 1114 still work, even if the guest is using ZFS. Legacy behavior can be 1115 restored by setting vfs.zfs.vol.recursive=1. 1116 111720160119: 1118 The NONE and HPN patches has been removed from OpenSSH. They are 1119 still available in the security/openssh-portable port. 1120 112120160113: 1122 With the addition of ypldap(8), a new _ypldap user is now required 1123 during installworld. "mergemaster -p" can be used to add the user 1124 prior to installworld, as documented in the handbook. 1125 112620151216: 1127 The tftp loader (pxeboot) now uses the option root-path directive. As a 1128 consequence it no longer looks for a pxeboot.4th file on the tftp 1129 server. Instead it uses the regular /boot infrastructure as with the 1130 other loaders. 1131 113220151211: 1133 The code to start recording plug and play data into the modules has 1134 been committed. While the old tools will properly build a new kernel, 1135 a number of warnings about "unknown metadata record 4" will be produced 1136 for an older kldxref. To avoid such warnings, make sure to rebuild 1137 the kernel toolchain (or world). Make sure that you have r292078 or 1138 later when trying to build 292077 or later before rebuilding. 1139 114020151207: 1141 Debug data files are now built by default with 'make buildworld' and 1142 installed with 'make installworld'. This facilitates debugging but 1143 requires more disk space both during the build and for the installed 1144 world. Debug files may be disabled by setting WITHOUT_DEBUG_FILES=yes 1145 in src.conf(5). 1146 114720151130: 1148 r291527 changed the internal interface between the nfsd.ko and 1149 nfscommon.ko modules. As such, they must both be upgraded to-gether. 1150 __FreeBSD_version has been bumped because of this. 1151 115220151108: 1153 Add support for unicode collation strings leads to a change of 1154 order of files listed by ls(1) for example. To get back to the old 1155 behaviour, set LC_COLLATE environment variable to "C". 1156 1157 Databases administrators will need to reindex their databases given 1158 collation results will be different. 1159 1160 Due to a bug in install(1) it is recommended to remove the ancient 1161 locales before running make installworld. 1162 1163 rm -rf /usr/share/locale/* 1164 116520151030: 1166 The OpenSSL has been upgraded to 1.0.2d. Any binaries requiring 1167 libcrypto.so.7 or libssl.so.7 must be recompiled. 1168 116920151020: 1170 Qlogic 24xx/25xx firmware images were updated from 5.5.0 to 7.3.0. 1171 Kernel modules isp_2400_multi and isp_2500_multi were removed and 1172 should be replaced with isp_2400 and isp_2500 modules respectively. 1173 117420151017: 1175 The build previously allowed using 'make -n' to not recurse into 1176 sub-directories while showing what commands would be executed, and 1177 'make -n -n' to recursively show commands. Now 'make -n' will recurse 1178 and 'make -N' will not. 1179 118020151012: 1181 If you specify SENDMAIL_MC or SENDMAIL_CF in make.conf, mergemaster 1182 and etcupdate will now use this file. A custom sendmail.cf is now 1183 updated via this mechanism rather than via installworld. If you had 1184 excluded sendmail.cf in mergemaster.rc or etcupdate.conf, you may 1185 want to remove the exclusion or change it to "always install". 1186 /etc/mail/sendmail.cf is now managed the same way regardless of 1187 whether SENDMAIL_MC/SENDMAIL_CF is used. If you are not using 1188 SENDMAIL_MC/SENDMAIL_CF there should be no change in behavior. 1189 119020151011: 1191 Compatibility shims for legacy ATA device names have been removed. 1192 It includes ATA_STATIC_ID kernel option, kern.cam.ada.legacy_aliases 1193 and kern.geom.raid.legacy_aliases loader tunables, kern.devalias.* 1194 environment variables, /dev/ad* and /dev/ar* symbolic links. 1195 119620151006: 1197 Clang, llvm, lldb, compiler-rt and libc++ have been upgraded to 3.7.0. 1198 Please see the 20141231 entry below for information about prerequisites 1199 and upgrading, if you are not already using clang 3.5.0 or higher. 1200 120120150924: 1202 Kernel debug files have been moved to /usr/lib/debug/boot/kernel/, 1203 and renamed from .symbols to .debug. This reduces the size requirements 1204 on the boot partition or file system and provides consistency with 1205 userland debug files. 1206 1207 When using the supported kernel installation method the 1208 /usr/lib/debug/boot/kernel directory will be renamed (to kernel.old) 1209 as is done with /boot/kernel. 1210 1211 Developers wishing to maintain the historical behavior of installing 1212 debug files in /boot/kernel/ can set KERN_DEBUGDIR="" in src.conf(5). 1213 121420150827: 1215 The wireless drivers had undergone changes that remove the 'parent 1216 interface' from the ifconfig -l output. The rc.d network scripts 1217 used to check presence of a parent interface in the list, so old 1218 scripts would fail to start wireless networking. Thus, etcupdate(3) 1219 or mergemaster(8) run is required after kernel update, to update your 1220 rc.d scripts in /etc. 1221 122220150827: 1223 pf no longer supports 'scrub fragment crop' or 'scrub fragment drop-ovl' 1224 These configurations are now automatically interpreted as 1225 'scrub fragment reassemble'. 1226 122720150817: 1228 Kernel-loadable modules for the random(4) device are back. To use 1229 them, the kernel must have 1230 1231 device random 1232 options RANDOM_LOADABLE 1233 1234 kldload(8) can then be used to load random_fortuna.ko 1235 or random_yarrow.ko. Please note that due to the indirect 1236 function calls that the loadable modules need to provide, 1237 the build-in variants will be slightly more efficient. 1238 1239 The random(4) kernel option RANDOM_DUMMY has been retired due to 1240 unpopularity. It was not all that useful anyway. 1241 124220150813: 1243 The WITHOUT_ELFTOOLCHAIN_TOOLS src.conf(5) knob has been retired. 1244 Control over building the ELF Tool Chain tools is now provided by 1245 the WITHOUT_TOOLCHAIN knob. 1246 124720150810: 1248 The polarity of Pulse Per Second (PPS) capture events with the 1249 uart(4) driver has been corrected. Prior to this change the PPS 1250 "assert" event corresponded to the trailing edge of a positive PPS 1251 pulse and the "clear" event was the leading edge of the next pulse. 1252 1253 As the width of a PPS pulse in a typical GPS receiver is on the 1254 order of 1 millisecond, most users will not notice any significant 1255 difference with this change. 1256 1257 Anyone who has compensated for the historical polarity reversal by 1258 configuring a negative offset equal to the pulse width will need to 1259 remove that workaround. 1260 126120150809: 1262 The default group assigned to /dev/dri entries has been changed 1263 from 'wheel' to 'video' with the id of '44'. If you want to have 1264 access to the dri devices please add yourself to the video group 1265 with: 1266 1267 # pw groupmod video -m $USER 1268 126920150806: 1270 The menu.rc and loader.rc files will now be replaced during 1271 upgrades. Please migrate local changes to menu.rc.local and 1272 loader.rc.local instead. 1273 127420150805: 1275 GNU Binutils versions of addr2line, c++filt, nm, readelf, size, 1276 strings and strip have been removed. The src.conf(5) knob 1277 WITHOUT_ELFTOOLCHAIN_TOOLS no longer provides the binutils tools. 1278 127920150728: 1280 As ZFS requires more kernel stack pages than is the default on some 1281 architectures e.g. i386, it now warns if KSTACK_PAGES is less than 1282 ZFS_MIN_KSTACK_PAGES (which is 4 at the time of writing). 1283 1284 Please consider using 'options KSTACK_PAGES=X' where X is greater 1285 than or equal to ZFS_MIN_KSTACK_PAGES i.e. 4 in such configurations. 1286 128720150706: 1288 sendmail has been updated to 8.15.2. Starting with FreeBSD 11.0 1289 and sendmail 8.15, sendmail uses uncompressed IPv6 addresses by 1290 default, i.e., they will not contain "::". For example, instead 1291 of ::1, it will be 0:0:0:0:0:0:0:1. This permits a zero subnet 1292 to have a more specific match, such as different map entries for 1293 IPv6:0:0 vs IPv6:0. This change requires that configuration 1294 data (including maps, files, classes, custom ruleset, etc.) must 1295 use the same format, so make certain such configuration data is 1296 upgrading. As a very simple check search for patterns like 1297 'IPv6:[0-9a-fA-F:]*::' and 'IPv6::'. To return to the old 1298 behavior, set the m4 option confUSE_COMPRESSED_IPV6_ADDRESSES or 1299 the cf option UseCompressedIPv6Addresses. 1300 130120150630: 1302 The default kernel entropy-processing algorithm is now 1303 Fortuna, replacing Yarrow. 1304 1305 Assuming you have 'device random' in your kernel config 1306 file, the configurations allow a kernel option to override 1307 this default. You may choose *ONE* of: 1308 1309 options RANDOM_YARROW # Legacy /dev/random algorithm. 1310 options RANDOM_DUMMY # Blocking-only driver. 1311 1312 If you have neither, you get Fortuna. For most people, 1313 read no further, Fortuna will give a /dev/random that works 1314 like it always used to, and the difference will be irrelevant. 1315 1316 If you remove 'device random', you get *NO* kernel-processed 1317 entropy at all. This may be acceptable to folks building 1318 embedded systems, but has complications. Carry on reading, 1319 and it is assumed you know what you need. 1320 1321 *PLEASE* read random(4) and random(9) if you are in the 1322 habit of tweaking kernel configs, and/or if you are a member 1323 of the embedded community, wanting specific and not-usual 1324 behaviour from your security subsystems. 1325 1326 NOTE!! If you use RANDOM_DUMMY and/or have no 'device 1327 random', you will NOT have a functioning /dev/random, and 1328 many cryptographic features will not work, including SSH. 1329 You may also find strange behaviour from the random(3) set 1330 of library functions, in particular sranddev(3), srandomdev(3) 1331 and arc4random(3). The reason for this is that the KERN_ARND 1332 sysctl only returns entropy if it thinks it has some to 1333 share, and with RANDOM_DUMMY or no 'device random' this 1334 will never happen. 1335 133620150623: 1337 An additional fix for the issue described in the 20150614 sendmail 1338 entry below has been committed in revision 284717. 1339 134020150616: 1341 FreeBSD's old make (fmake) has been removed from the system. It is 1342 available as the devel/fmake port or via pkg install fmake. 1343 134420150615: 1345 The fix for the issue described in the 20150614 sendmail entry 1346 below has been committed in revision 284436. The work 1347 around described in that entry is no longer needed unless the 1348 default setting is overridden by a confDH_PARAMETERS configuration 1349 setting of '5' or pointing to a 512 bit DH parameter file. 1350 135120150614: 1352 ALLOW_DEPRECATED_ATF_TOOLS/ATFFILE support has been removed from 1353 atf.test.mk (included from bsd.test.mk). Please upgrade devel/atf 1354 and devel/kyua to version 0.20+ and adjust any calling code to work 1355 with Kyuafile and kyua. 1356 135720150614: 1358 The import of openssl to address the FreeBSD-SA-15:10.openssl 1359 security advisory includes a change which rejects handshakes 1360 with DH parameters below 768 bits. sendmail releases prior 1361 to 8.15.2 (not yet released), defaulted to a 512 bit 1362 DH parameter setting for client connections. To work around 1363 this interoperability, sendmail can be configured to use a 1364 2048 bit DH parameter by: 1365 1366 1. Edit /etc/mail/`hostname`.mc 1367 2. If a setting for confDH_PARAMETERS does not exist or 1368 exists and is set to a string beginning with '5', 1369 replace it with '2'. 1370 3. If a setting for confDH_PARAMETERS exists and is set to 1371 a file path, create a new file with: 1372 openssl dhparam -out /path/to/file 2048 1373 4. Rebuild the .cf file: 1374 cd /etc/mail/; make; make install 1375 5. Restart sendmail: 1376 cd /etc/mail/; make restart 1377 1378 A sendmail patch is coming, at which time this file will be 1379 updated. 1380 138120150604: 1382 Generation of legacy formatted entries have been disabled by default 1383 in pwd_mkdb(8), as all base system consumers of the legacy formatted 1384 entries were converted to use the new format by default when the new, 1385 machine independent format have been added and supported since FreeBSD 1386 5.x. 1387 1388 Please see the pwd_mkdb(8) manual page for further details. 1389 139020150525: 1391 Clang and llvm have been upgraded to 3.6.1 release. Please see the 1392 20141231 entry below for information about prerequisites and upgrading, 1393 if you are not already using 3.5.0 or higher. 1394 139520150521: 1396 TI platform code switched to using vendor DTS files and this update 1397 may break existing systems running on Beaglebone, Beaglebone Black, 1398 and Pandaboard: 1399 1400 - dtb files should be regenerated/reinstalled. Filenames are the 1401 same but content is different now 1402 - GPIO addressing was changed, now each GPIO bank (32 pins per bank) 1403 has its own /dev/gpiocX device, e.g. pin 121 on /dev/gpioc0 in old 1404 addressing scheme is now pin 25 on /dev/gpioc3. 1405 - Pandaboard: /etc/ttys should be updated, serial console device is 1406 now /dev/ttyu2, not /dev/ttyu0 1407 140820150501: 1409 soelim(1) from gnu/usr.bin/groff has been replaced by usr.bin/soelim. 1410 If you need the GNU extension from groff soelim(1), install groff 1411 from package: pkg install groff, or via ports: textproc/groff. 1412 141320150423: 1414 chmod, chflags, chown and chgrp now affect symlinks in -R mode as 1415 defined in symlink(7); previously symlinks were silently ignored. 1416 141720150415: 1418 The const qualifier has been removed from iconv(3) to comply with 1419 POSIX. The ports tree is aware of this from r384038 onwards. 1420 142120150416: 1422 Libraries specified by LIBADD in Makefiles must have a corresponding 1423 DPADD_<lib> variable to ensure correct dependencies. This is now 1424 enforced in src.libnames.mk. 1425 142620150324: 1427 From legacy ata(4) driver was removed support for SATA controllers 1428 supported by more functional drivers ahci(4), siis(4) and mvs(4). 1429 Kernel modules ataahci and ataadaptec were removed completely, 1430 replaced by ahci and mvs modules respectively. 1431 143220150315: 1433 Clang, llvm and lldb have been upgraded to 3.6.0 release. Please see 1434 the 20141231 entry below for information about prerequisites and 1435 upgrading, if you are not already using 3.5.0 or higher. 1436 143720150307: 1438 The 32-bit PowerPC kernel has been changed to a position-independent 1439 executable. This can only be booted with a version of loader(8) 1440 newer than January 31, 2015, so make sure to update both world and 1441 kernel before rebooting. 1442 144320150217: 1444 If you are running a -CURRENT kernel since r273872 (Oct 30th, 2014), 1445 but before r278950, the RNG was not seeded properly. Immediately 1446 upgrade the kernel to r278950 or later and regenerate any keys (e.g. 1447 ssh keys or openssl keys) that were generated w/ a kernel from that 1448 range. This does not affect programs that directly used /dev/random 1449 or /dev/urandom. All userland uses of arc4random(3) are affected. 1450 145120150210: 1452 The autofs(4) ABI was changed in order to restore binary compatibility 1453 with 10.1-RELEASE. The automountd(8) daemon needs to be rebuilt to work 1454 with the new kernel. 1455 145620150131: 1457 The powerpc64 kernel has been changed to a position-independent 1458 executable. This can only be booted with a new version of loader(8), 1459 so make sure to update both world and kernel before rebooting. 1460 146120150118: 1462 Clang and llvm have been upgraded to 3.5.1 release. This is a bugfix 1463 only release, no new features have been added. Please see the 20141231 1464 entry below for information about prerequisites and upgrading, if you 1465 are not already using 3.5.0. 1466 146720150107: 1468 ELF tools addr2line, elfcopy (strip), nm, size, and strings are now 1469 taken from the ELF Tool Chain project rather than GNU binutils. They 1470 should be drop-in replacements, with the addition of arm64 support. 1471 The WITHOUT_ELFTOOLCHAIN_TOOLS= knob may be used to obtain the 1472 binutils tools, if necessary. See 20150805 for updated information. 1473 147420150105: 1475 The default Unbound configuration now enables remote control 1476 using a local socket. Users who have already enabled the 1477 local_unbound service should regenerate their configuration 1478 by running "service local_unbound setup" as root. 1479 148020150102: 1481 The GNU texinfo and GNU info pages have been removed. 1482 To be able to view GNU info pages please install texinfo from ports. 1483 148420141231: 1485 Clang, llvm and lldb have been upgraded to 3.5.0 release. 1486 1487 As of this release, a prerequisite for building clang, llvm and lldb is 1488 a C++11 capable compiler and C++11 standard library. This means that to 1489 be able to successfully build the cross-tools stage of buildworld, with 1490 clang as the bootstrap compiler, your system compiler or cross compiler 1491 should either be clang 3.3 or later, or gcc 4.8 or later, and your 1492 system C++ library should be libc++, or libdstdc++ from gcc 4.8 or 1493 later. 1494 1495 On any standard FreeBSD 10.x or 11.x installation, where clang and 1496 libc++ are on by default (that is, on x86 or arm), this should work out 1497 of the box. 1498 1499 On 9.x installations where clang is enabled by default, e.g. on x86 and 1500 powerpc, libc++ will not be enabled by default, so libc++ should be 1501 built (with clang) and installed first. If both clang and libc++ are 1502 missing, build clang first, then use it to build libc++. 1503 1504 On 8.x and earlier installations, upgrade to 9.x first, and then follow 1505 the instructions for 9.x above. 1506 1507 Sparc64 and mips users are unaffected, as they still use gcc 4.2.1 by 1508 default, and do not build clang. 1509 1510 Many embedded systems are resource constrained, and will not be able to 1511 build clang in a reasonable time, or in some cases at all. In those 1512 cases, cross building bootable systems on amd64 is a workaround. 1513 1514 This new version of clang introduces a number of new warnings, of which 1515 the following are most likely to appear: 1516 1517 -Wabsolute-value 1518 1519 This warns in two cases, for both C and C++: 1520 * When the code is trying to take the absolute value of an unsigned 1521 quantity, which is effectively a no-op, and almost never what was 1522 intended. The code should be fixed, if at all possible. If you are 1523 sure that the unsigned quantity can be safely cast to signed, without 1524 loss of information or undefined behavior, you can add an explicit 1525 cast, or disable the warning. 1526 1527 * When the code is trying to take an absolute value, but the called 1528 abs() variant is for the wrong type, which can lead to truncation. 1529 If you want to disable the warning instead of fixing the code, please 1530 make sure that truncation will not occur, or it might lead to unwanted 1531 side-effects. 1532 1533 -Wtautological-undefined-compare and 1534 -Wundefined-bool-conversion 1535 1536 These warn when C++ code is trying to compare 'this' against NULL, while 1537 'this' should never be NULL in well-defined C++ code. However, there is 1538 some legacy (pre C++11) code out there, which actively abuses this 1539 feature, which was less strictly defined in previous C++ versions. 1540 1541 Squid and openjdk do this, for example. The warning can be turned off 1542 for C++98 and earlier, but compiling the code in C++11 mode might result 1543 in unexpected behavior; for example, the parts of the program that are 1544 unreachable could be optimized away. 1545 154620141222: 1547 The old NFS client and server (kernel options NFSCLIENT, NFSSERVER) 1548 kernel sources have been removed. The .h files remain, since some 1549 utilities include them. This will need to be fixed later. 1550 If "mount -t oldnfs ..." is attempted, it will fail. 1551 If the "-o" option on mountd(8), nfsd(8) or nfsstat(1) is used, 1552 the utilities will report errors. 1553 155420141121: 1555 The handling of LOCAL_LIB_DIRS has been altered to skip addition of 1556 directories to top level SUBDIR variable when their parent 1557 directory is included in LOCAL_DIRS. Users with build systems with 1558 such hierarchies and without SUBDIR entries in the parent 1559 directory Makefiles should add them or add the directories to 1560 LOCAL_DIRS. 1561 156220141109: 1563 faith(4) and faithd(8) have been removed from the base system. Faith 1564 has been obsolete for a very long time. 1565 156620141104: 1567 vt(4), the new console driver, is enabled by default. It brings 1568 support for Unicode and double-width characters, as well as 1569 support for UEFI and integration with the KMS kernel video 1570 drivers. 1571 1572 You may need to update your console settings in /etc/rc.conf, 1573 most probably the keymap. During boot, /etc/rc.d/syscons will 1574 indicate what you need to do. 1575 1576 vt(4) still has issues and lacks some features compared to 1577 syscons(4). See the wiki for up-to-date information: 1578 https://wiki.freebsd.org/Newcons 1579 1580 If you want to keep using syscons(4), you can do so by adding 1581 the following line to /boot/loader.conf: 1582 kern.vty=sc 1583 158420141102: 1585 pjdfstest has been integrated into kyua as an opt-in test suite. 1586 Please see share/doc/pjdfstest/README for more details on how to 1587 execute it. 1588 158920141009: 1590 gperf has been removed from the base system for architectures 1591 that use clang. Ports that require gperf will obtain it from the 1592 devel/gperf port. 1593 159420140923: 1595 pjdfstest has been moved from tools/regression/pjdfstest to 1596 contrib/pjdfstest . 1597 159820140922: 1599 At svn r271982, The default linux compat kernel ABI has been adjusted 1600 to 2.6.18 in support of the linux-c6 compat ports infrastructure 1601 update. If you wish to continue using the linux-f10 compat ports, 1602 add compat.linux.osrelease=2.6.16 to your local sysctl.conf. Users are 1603 encouraged to update their linux-compat packages to linux-c6 during 1604 their next update cycle. 1605 160620140729: 1607 The ofwfb driver, used to provide a graphics console on PowerPC when 1608 using vt(4), no longer allows mmap() of all physical memory. This 1609 will prevent Xorg on PowerPC with some ATI graphics cards from 1610 initializing properly unless x11-servers/xorg-server is updated to 1611 1.12.4_8 or newer. 1612 161320140723: 1614 The xdev targets have been converted to using TARGET and 1615 TARGET_ARCH instead of XDEV and XDEV_ARCH. 1616 161720140719: 1618 The default unbound configuration has been modified to address 1619 issues with reverse lookups on networks that use private 1620 address ranges. If you use the local_unbound service, run 1621 "service local_unbound setup" as root to regenerate your 1622 configuration, then "service local_unbound reload" to load the 1623 new configuration. 1624 162520140709: 1626 The GNU texinfo and GNU info pages are not built and installed 1627 anymore, WITH_INFO knob has been added to allow to built and install 1628 them again. 1629 UPDATE: see 20150102 entry on texinfo's removal 1630 163120140708: 1632 The GNU readline library is now an INTERNALLIB - that is, it is 1633 statically linked into consumers (GDB and variants) in the base 1634 system, and the shared library is no longer installed. The 1635 devel/readline port is available for third party software that 1636 requires readline. 1637 163820140702: 1639 The Itanium architecture (ia64) has been removed from the list of 1640 known architectures. This is the first step in the removal of the 1641 architecture. 1642 164320140701: 1644 Commit r268115 has added NFSv4.1 server support, merged from 1645 projects/nfsv4.1-server. Since this includes changes to the 1646 internal interfaces between the NFS related modules, a full 1647 build of the kernel and modules will be necessary. 1648 __FreeBSD_version has been bumped. 1649 165020140629: 1651 The WITHOUT_VT_SUPPORT kernel config knob has been renamed 1652 WITHOUT_VT. (The other _SUPPORT knobs have a consistent meaning 1653 which differs from the behaviour controlled by this knob.) 1654 165520140619: 1656 Maximal length of the serial number in CTL was increased from 16 to 1657 64 chars, that breaks ABI. All CTL-related tools, such as ctladm 1658 and ctld, need to be rebuilt to work with a new kernel. 1659 166020140606: 1661 The libatf-c and libatf-c++ major versions were downgraded to 0 and 1662 1 respectively to match the upstream numbers. They were out of 1663 sync because, when they were originally added to FreeBSD, the 1664 upstream versions were not respected. These libraries are private 1665 and not yet built by default, so renumbering them should be a 1666 non-issue. However, unclean source trees will yield broken test 1667 programs once the operator executes "make delete-old-libs" after a 1668 "make installworld". 1669 1670 Additionally, the atf-sh binary was made private by moving it into 1671 /usr/libexec/. Already-built shell test programs will keep the 1672 path to the old binary so they will break after "make delete-old" 1673 is run. 1674 1675 If you are using WITH_TESTS=yes (not the default), wipe the object 1676 tree and rebuild from scratch to prevent spurious test failures. 1677 This is only needed once: the misnumbered libraries and misplaced 1678 binaries have been added to OptionalObsoleteFiles.inc so they will 1679 be removed during a clean upgrade. 1680 168120140512: 1682 Clang and llvm have been upgraded to 3.4.1 release. 1683 168420140508: 1685 We bogusly installed src.opts.mk in /usr/share/mk. This file should 1686 be removed to avoid issues in the future (and has been added to 1687 ObsoleteFiles.inc). 1688 168920140505: 1690 /etc/src.conf now affects only builds of the FreeBSD src tree. In the 1691 past, it affected all builds that used the bsd.*.mk files. The old 1692 behavior was a bug, but people may have relied upon it. To get this 1693 behavior back, you can .include /etc/src.conf from /etc/make.conf 1694 (which is still global and isn't changed). This also changes the 1695 behavior of incremental builds inside the tree of individual 1696 directories. Set MAKESYSPATH to ".../share/mk" to do that. 1697 Although this has survived make universe and some upgrade scenarios, 1698 other upgrade scenarios may have broken. At least one form of 1699 temporary breakage was fixed with MAKESYSPATH settings for buildworld 1700 as well... In cases where MAKESYSPATH isn't working with this 1701 setting, you'll need to set it to the full path to your tree. 1702 1703 One side effect of all this cleaning up is that bsd.compiler.mk 1704 is no longer implicitly included by bsd.own.mk. If you wish to 1705 use COMPILER_TYPE, you must now explicitly include bsd.compiler.mk 1706 as well. 1707 170820140430: 1709 The lindev device has been removed since /dev/full has been made a 1710 standard device. __FreeBSD_version has been bumped. 1711 171220140424: 1713 The knob WITHOUT_VI was added to the base system, which controls 1714 building ex(1), vi(1), etc. Older releases of FreeBSD required ex(1) 1715 in order to reorder files share/termcap and didn't build ex(1) as a 1716 build tool, so building/installing with WITH_VI is highly advised for 1717 build hosts for older releases. 1718 1719 This issue has been fixed in stable/9 and stable/10 in r277022 and 1720 r276991, respectively. 1721 172220140418: 1723 The YES_HESIOD knob has been removed. It has been obsolete for 1724 a decade. Please move to using WITH_HESIOD instead or your builds 1725 will silently lack HESIOD. 1726 172720140405: 1728 The uart(4) driver has been changed with respect to its handling 1729 of the low-level console. Previously the uart(4) driver prevented 1730 any process from changing the baudrate or the CLOCAL and HUPCL 1731 control flags. By removing the restrictions, operators can make 1732 changes to the serial console port without having to reboot. 1733 However, when getty(8) is started on the serial device that is 1734 associated with the low-level console, a misconfigured terminal 1735 line in /etc/ttys will now have a real impact. 1736 Before upgrading the kernel, make sure that /etc/ttys has the 1737 serial console device configured as 3wire without baudrate to 1738 preserve the previous behaviour. E.g: 1739 ttyu0 "/usr/libexec/getty 3wire" vt100 on secure 1740 174120140306: 1742 Support for libwrap (TCP wrappers) in rpcbind was disabled by default 1743 to improve performance. To re-enable it, if needed, run rpcbind 1744 with command line option -W. 1745 174620140226: 1747 Switched back to the GPL dtc compiler due to updates in the upstream 1748 dts files not being supported by the BSDL dtc compiler. You will need 1749 to rebuild your kernel toolchain to pick up the new compiler. Core dumps 1750 may result while building dtb files during a kernel build if you fail 1751 to do so. Set WITHOUT_GPL_DTC if you require the BSDL compiler. 1752 175320140216: 1754 Clang and llvm have been upgraded to 3.4 release. 1755 175620140216: 1757 The nve(4) driver has been removed. Please use the nfe(4) driver 1758 for NVIDIA nForce MCP Ethernet adapters instead. 1759 176020140212: 1761 An ABI incompatibility crept into the libc++ 3.4 import in r261283. 1762 This could cause certain C++ applications using shared libraries built 1763 against the previous version of libc++ to crash. The incompatibility 1764 has now been fixed, but any C++ applications or shared libraries built 1765 between r261283 and r261801 should be recompiled. 1766 176720140204: 1768 OpenSSH will now ignore errors caused by kernel lacking of Capsicum 1769 capability mode support. Please note that enabling the feature in 1770 kernel is still highly recommended. 1771 177220140131: 1773 OpenSSH is now built with sandbox support, and will use sandbox as 1774 the default privilege separation method. This requires Capsicum 1775 capability mode support in kernel. 1776 177720140128: 1778 The libelf and libdwarf libraries have been updated to newer 1779 versions from upstream. Shared library version numbers for 1780 these two libraries were bumped. Any ports or binaries 1781 requiring these two libraries should be recompiled. 1782 __FreeBSD_version is bumped to 1100006. 1783 178420140110: 1785 If a Makefile in a tests/ directory was auto-generating a Kyuafile 1786 instead of providing an explicit one, this would prevent such 1787 Makefile from providing its own Kyuafile in the future during 1788 NO_CLEAN builds. This has been fixed in the Makefiles but manual 1789 intervention is needed to clean an objdir if you use NO_CLEAN: 1790 # find /usr/obj -name Kyuafile | xargs rm -f 1791 179220131213: 1793 The behavior of gss_pseudo_random() for the krb5 mechanism 1794 has changed, for applications requesting a longer random string 1795 than produced by the underlying enctype's pseudo-random() function. 1796 In particular, the random string produced from a session key of 1797 enctype aes256-cts-hmac-sha1-96 or aes256-cts-hmac-sha1-96 will 1798 be different at the 17th octet and later, after this change. 1799 The counter used in the PRF+ construction is now encoded as a 1800 big-endian integer in accordance with RFC 4402. 1801 __FreeBSD_version is bumped to 1100004. 1802 180320131108: 1804 The WITHOUT_ATF build knob has been removed and its functionality 1805 has been subsumed into the more generic WITHOUT_TESTS. If you were 1806 using the former to disable the build of the ATF libraries, you 1807 should change your settings to use the latter. 1808 180920131025: 1810 The default version of mtree is nmtree which is obtained from 1811 NetBSD. The output is generally the same, but may vary 1812 slightly. If you found you need identical output adding 1813 "-F freebsd9" to the command line should do the trick. For the 1814 time being, the old mtree is available as fmtree. 1815 181620131014: 1817 libbsdyml has been renamed to libyaml and moved to /usr/lib/private. 1818 This will break ports-mgmt/pkg. Rebuild the port, or upgrade to pkg 1819 1.1.4_8 and verify bsdyml not linked in, before running "make 1820 delete-old-libs": 1821 # make -C /usr/ports/ports-mgmt/pkg build deinstall install clean 1822 or 1823 # pkg install pkg; ldd /usr/local/sbin/pkg | grep bsdyml 1824 182520131010: 1826 The stable/10 branch has been created in subversion from head 1827 revision r256279. 1828 1829COMMON ITEMS: 1830 1831 General Notes 1832 ------------- 1833 Avoid using make -j when upgrading. While generally safe, there are 1834 sometimes problems using -j to upgrade. If your upgrade fails with 1835 -j, please try again without -j. From time to time in the past there 1836 have been problems using -j with buildworld and/or installworld. This 1837 is especially true when upgrading between "distant" versions (eg one 1838 that cross a major release boundary or several minor releases, or when 1839 several months have passed on the -current branch). 1840 1841 Sometimes, obscure build problems are the result of environment 1842 poisoning. This can happen because the make utility reads its 1843 environment when searching for values for global variables. To run 1844 your build attempts in an "environmental clean room", prefix all make 1845 commands with 'env -i '. See the env(1) manual page for more details. 1846 1847 When upgrading from one major version to another it is generally best to 1848 upgrade to the latest code in the currently installed branch first, then 1849 do an upgrade to the new branch. This is the best-tested upgrade path, 1850 and has the highest probability of being successful. Please try this 1851 approach if you encounter problems with a major version upgrade. Since 1852 the stable 4.x branch point, one has generally been able to upgrade from 1853 anywhere in the most recent stable branch to head / current (or even the 1854 last couple of stable branches). See the top of this file when there's 1855 an exception. 1856 1857 When upgrading a live system, having a root shell around before 1858 installing anything can help undo problems. Not having a root shell 1859 around can lead to problems if pam has changed too much from your 1860 starting point to allow continued authentication after the upgrade. 1861 1862 This file should be read as a log of events. When a later event changes 1863 information of a prior event, the prior event should not be deleted. 1864 Instead, a pointer to the entry with the new information should be 1865 placed in the old entry. Readers of this file should also sanity check 1866 older entries before relying on them blindly. Authors of new entries 1867 should write them with this in mind. 1868 1869 ZFS notes 1870 --------- 1871 When upgrading the boot ZFS pool to a new version, always follow 1872 these two steps: 1873 1874 1.) recompile and reinstall the ZFS boot loader and boot block 1875 (this is part of "make buildworld" and "make installworld") 1876 1877 2.) update the ZFS boot block on your boot drive 1878 1879 The following example updates the ZFS boot block on the first 1880 partition (freebsd-boot) of a GPT partitioned drive ada0: 1881 "gpart bootcode -p /boot/gptzfsboot -i 1 ada0" 1882 1883 Non-boot pools do not need these updates. 1884 1885 To build a kernel 1886 ----------------- 1887 If you are updating from a prior version of FreeBSD (even one just 1888 a few days old), you should follow this procedure. It is the most 1889 failsafe as it uses a /usr/obj tree with a fresh mini-buildworld, 1890 1891 make kernel-toolchain 1892 make -DALWAYS_CHECK_MAKE buildkernel KERNCONF=YOUR_KERNEL_HERE 1893 make -DALWAYS_CHECK_MAKE installkernel KERNCONF=YOUR_KERNEL_HERE 1894 1895 To test a kernel once 1896 --------------------- 1897 If you just want to boot a kernel once (because you are not sure 1898 if it works, or if you want to boot a known bad kernel to provide 1899 debugging information) run 1900 make installkernel KERNCONF=YOUR_KERNEL_HERE KODIR=/boot/testkernel 1901 nextboot -k testkernel 1902 1903 To rebuild everything and install it on the current system. 1904 ----------------------------------------------------------- 1905 # Note: sometimes if you are running current you gotta do more than 1906 # is listed here if you are upgrading from a really old current. 1907 1908 <make sure you have good level 0 dumps> 1909 make buildworld 1910 make buildkernel KERNCONF=YOUR_KERNEL_HERE 1911 make installkernel KERNCONF=YOUR_KERNEL_HERE 1912 [1] 1913 <reboot in single user> [3] 1914 mergemaster -Fp [5] 1915 make installworld 1916 mergemaster -Fi [4] 1917 make delete-old [6] 1918 <reboot> 1919 1920 To cross-install current onto a separate partition 1921 -------------------------------------------------- 1922 # In this approach we use a separate partition to hold 1923 # current's root, 'usr', and 'var' directories. A partition 1924 # holding "/", "/usr" and "/var" should be about 2GB in 1925 # size. 1926 1927 <make sure you have good level 0 dumps> 1928 <boot into -stable> 1929 make buildworld 1930 make buildkernel KERNCONF=YOUR_KERNEL_HERE 1931 <maybe newfs current's root partition> 1932 <mount current's root partition on directory ${CURRENT_ROOT}> 1933 make installworld DESTDIR=${CURRENT_ROOT} -DDB_FROM_SRC 1934 make distribution DESTDIR=${CURRENT_ROOT} # if newfs'd 1935 make installkernel KERNCONF=YOUR_KERNEL_HERE DESTDIR=${CURRENT_ROOT} 1936 cp /etc/fstab ${CURRENT_ROOT}/etc/fstab # if newfs'd 1937 <edit ${CURRENT_ROOT}/etc/fstab to mount "/" from the correct partition> 1938 <reboot into current> 1939 <do a "native" rebuild/install as described in the previous section> 1940 <maybe install compatibility libraries from ports/misc/compat*> 1941 <reboot> 1942 1943 1944 To upgrade in-place from stable to current 1945 ---------------------------------------------- 1946 <make sure you have good level 0 dumps> 1947 make buildworld [9] 1948 make buildkernel KERNCONF=YOUR_KERNEL_HERE [8] 1949 make installkernel KERNCONF=YOUR_KERNEL_HERE 1950 [1] 1951 <reboot in single user> [3] 1952 mergemaster -Fp [5] 1953 make installworld 1954 mergemaster -Fi [4] 1955 make delete-old [6] 1956 <reboot> 1957 1958 Make sure that you've read the UPDATING file to understand the 1959 tweaks to various things you need. At this point in the life 1960 cycle of current, things change often and you are on your own 1961 to cope. The defaults can also change, so please read ALL of 1962 the UPDATING entries. 1963 1964 Also, if you are tracking -current, you must be subscribed to 1965 freebsd-current@freebsd.org. Make sure that before you update 1966 your sources that you have read and understood all the recent 1967 messages there. If in doubt, please track -stable which has 1968 much fewer pitfalls. 1969 1970 [1] If you have third party modules, such as vmware, you 1971 should disable them at this point so they don't crash your 1972 system on reboot. 1973 1974 [3] From the bootblocks, boot -s, and then do 1975 fsck -p 1976 mount -u / 1977 mount -a 1978 sh /etc/rc.d/zfs start # mount zfs filesystem, if needed 1979 cd src # full path to source 1980 adjkerntz -i # if CMOS is wall time 1981 Also, when doing a major release upgrade, it is required that 1982 you boot into single user mode to do the installworld. 1983 1984 [4] Note: This step is non-optional. Failure to do this step 1985 can result in a significant reduction in the functionality of the 1986 system. Attempting to do it by hand is not recommended and those 1987 that pursue this avenue should read this file carefully, as well 1988 as the archives of freebsd-current and freebsd-hackers mailing lists 1989 for potential gotchas. The -U option is also useful to consider. 1990 See mergemaster(8) for more information. 1991 1992 [5] Usually this step is a no-op. However, from time to time 1993 you may need to do this if you get unknown user in the following 1994 step. It never hurts to do it all the time. You may need to 1995 install a new mergemaster (cd src/usr.sbin/mergemaster && make 1996 install) after the buildworld before this step if you last updated 1997 from current before 20130425 or from -stable before 20130430. 1998 1999 [6] This only deletes old files and directories. Old libraries 2000 can be deleted by "make delete-old-libs", but you have to make 2001 sure that no program is using those libraries anymore. 2002 2003 [8] The new kernel must be able to run existing binaries used by an 2004 installworld. When upgrading across major versions, the new kernel's 2005 configuration must include the correct COMPAT_FREEBSD<n> option for 2006 existing binaries (e.g. COMPAT_FREEBSD11 to run 11.x binaries). Failure 2007 to do so may leave you with a system that is hard to boot to recover. A 2008 GENERIC kernel will include suitable compatibility options to run 2009 binaries from older branches. Note that the ability to run binaries 2010 from unsupported branches is not guaranteed. 2011 2012 Make sure that you merge any new devices from GENERIC since the 2013 last time you updated your kernel config file.
