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 3420190620: 35 Entropy collection and the /dev/random device are no longer optional 36 components. The "device random" option has been removed. 37 Implementations of distilling algorithms can still be made loadable 38 with "options RANDOM_LOADABLE" (e.g., random_fortuna.ko). 39 4020190612: 41 Clang, llvm, lld, lldb, compiler-rt, libc++, libunwind and openmp have 42 been upgraded to 8.0.1. Please see the 20141231 entry below for 43 information about prerequisites and upgrading, if you are not already 44 using clang 3.5.0 or higher. 45 4620190608: 47 A fix was applied to i386 kernel modules to avoid panics with 48 dpcpu or vnet. Users need to recompile i386 kernel modules 49 having pcpu or vnet sections or they will refuse to load. 50 5120190513: 52 User-wired pages now have their own counter, 53 vm.stats.vm.v_user_wire_count. The vm.max_wired sysctl was renamed 54 to vm.max_user_wired and changed from an unsigned int to an unsigned 55 long. bhyve VMs wired with the -S are now subject to the user 56 wiring limit; the vm.max_user_wired sysctl may need to be tuned to 57 avoid running into the limit. 58 5920190507: 60 The IPSEC option has been removed from GENERIC. Users requiring 61 ipsec(4) must now load the ipsec(4) kernel module. 62 6320190507: 64 The tap(4) driver has been folded into tun(4), and the module has been 65 renamed to tuntap. You should update any kld_load="if_tap" or 66 kld_load="if_tun" entries in /etc/rc.conf, if_tap_load="YES" or 67 if_tun_load="YES" entries in /boot/loader.conf to load the if_tuntap 68 module instead, and "device tap" or "device tun" entries in kernel 69 config files to select the tuntap device instead. 70 7120190418: 72 The following knobs have been added related to tradeoffs between 73 safe use of the random device and availability in the absence of 74 entropy: 75 76 kern.random.initial_seeding.bypass_before_seeding: tunable; set 77 non-zero to bypass the random device prior to seeding, or zero to 78 block random requests until the random device is initially seeded. 79 For now, set to 1 (unsafe) by default to restore pre-r346250 boot 80 availability properties. 81 82 kern.random.initial_seeding.read_random_bypassed_before_seeding: 83 read-only diagnostic sysctl that is set when bypass is enabled and 84 read_random(9) is bypassed, to enable programmatic handling of this 85 initial condition, if desired. 86 87 kern.random.initial_seeding.arc4random_bypassed_before_seeding: 88 Similar to the above, but for for arc4random(9) initial seeding. 89 90 kern.random.initial_seeding.disable_bypass_warnings: tunable; set 91 non-zero to disable warnings in dmesg when the same conditions are 92 met as for the diagnostic sysctls above. Defaults to zero, i.e., 93 produce warnings in dmesg when the conditions are met. 94 9520190416: 96 The loadable random module KPI has changed; the random_infra_init() 97 routine now requires a 3rd function pointer for a bool (*)(void) 98 method that returns true if the random device is seeded (and 99 therefore unblocked). 100 10120190404: 102 r345895 reverts r320698. This implies that an nfsuserd(8) daemon 103 built from head sources between r320757 (July 6, 2017) and 104 r338192 (Aug. 22, 2018) will not work unless the "-use-udpsock" 105 is added to the command line. 106 nfsuserd daemons built from head sources that are post-r338192 are 107 not affected and should continue to work. 108 10920190320: 110 The fuse(4) module has been renamed to fusefs(4) for consistency with 111 other filesystems. You should update any kld_load="fuse" entries in 112 /etc/rc.conf, fuse_load="YES" entries in /boot/loader.conf, and 113 "options FUSE" entries in kernel config files. 114 11520190304: 116 Clang, llvm, lld, lldb, compiler-rt and libc++ have been upgraded to 117 8.0.0. Please see the 20141231 entry below for information about 118 prerequisites and upgrading, if you are not already using clang 3.5.0 119 or higher. 120 12120190226: 122 geom_uzip(4) depends on the new module xz. If geom_uzip is statically 123 compiled into your custom kernel, add 'device xz' statement to the 124 kernel config. 125 12620190219: 127 drm and drm2 have been removed from the tree. Please see 128 https://wiki.freebsd.org/Graphics for the latest information on 129 migrating to the drm ports. 130 13120190131: 132 Iflib is no longer unconditionally compiled into the kernel. Drivers 133 using iflib and statically compiled into the kernel, now require 134 the 'device iflib' config option. For the same drivers loaded as 135 modules on kernels not having 'device iflib', the iflib.ko module 136 is loaded automatically. 137 13820190125: 139 The IEEE80211_AMPDU_AGE and AH_SUPPORT_AR5416 kernel configuration 140 options no longer exist since r343219 and r343427 respectively; 141 nothing uses them, so they should be just removed from custom 142 kernel config files. 143 14420181230: 145 r342635 changes the way efibootmgr(8) works by requiring users to add 146 the -b (bootnum) parameter for commands where the bootnum was previously 147 specified with each option. For example 'efibootmgr -B 0001' is now 148 'efibootmgr -B -b 0001'. 149 15020181220: 151 r342286 modifies the NFSv4 server so that it obeys vfs.nfsd.nfs_privport 152 in the same as it is applied to NFSv2 and 3. This implies that NFSv4 153 servers that have vfs.nfsd.nfs_privport set will only allow mounts 154 from clients using a reserved port#. Since both the FreeBSD and Linux 155 NFSv4 clients use reserved port#s by default, this should not affect 156 most NFSv4 mounts. 157 15820181219: 159 The XLP config has been removed. We can't support 64-bit atomics in this 160 kernel because it is running in 32-bit mode. XLP users must transition 161 to running a 64-bit kernel (XLP64 or XLPN32). 162 163 The mips GXEMUL support has been removed from FreeBSD. MALTA* + qemu is 164 the preferred emulator today and we don't need two different ones. 165 166 The old sibyte / swarm / Broadcom BCM1250 support has been 167 removed from the mips port. 168 16920181211: 170 Clang, llvm, lld, lldb, compiler-rt and libc++ have been upgraded to 171 7.0.1. Please see the 20141231 entry below for information about 172 prerequisites and upgrading, if you are not already using clang 3.5.0 173 or higher. 174 17520181211: 176 Remove the timed and netdate programs from the base tree. Setting 177 the time with these daemons has been obsolete for over a decade. 178 17920181126: 180 On amd64, arm64 and armv7 (architectures that install LLVM's ld.lld 181 linker as /usr/bin/ld) GNU ld is no longer installed as ld.bfd, as 182 it produces broken binaries when ifuncs are in use. Users needing 183 GNU ld should install the binutils port or package. 184 18520181123: 186 The BSD crtbegin and crtend code has been enabled by default. It has 187 had extensive testing on amd64, arm64, and i386. It can be disabled 188 by building a world with -DWITHOUT_BSD_CRTBEGIN. 189 19020181115: 191 The set of CTM commands (ctm, ctm_smail, ctm_rmail, ctm_dequeue) 192 has been converted to a port (misc/ctm) and will be removed from 193 FreeBSD-13. It is available as a package (ctm) for all supported 194 FreeBSD versions. 195 19620181110: 197 The default newsyslog.conf(5) file has been changed to only include 198 files in /etc/newsyslog.conf.d/ and /usr/local/etc/newsyslog.conf.d/ if 199 the filenames end in '.conf' and do not begin with a '.'. 200 201 You should check the configuration files in these two directories match 202 this naming convention. You can verify which configuration files are 203 being included using the command: 204 $ newsyslog -Nrv 205 20620181015: 207 Ports for the DRM modules have been simplified. Now, amd64 users should 208 just install the drm-kmod port. All others should install 209 drm-legacy-kmod. 210 211 Graphics hardware that's newer than about 2010 usually works with 212 drm-kmod. For hardware older than 2013, however, some users will need 213 to use drm-legacy-kmod if drm-kmod doesn't work for them. Hardware older 214 than 2008 usually only works in drm-legacy-kmod. The graphics team can 215 only commit to hardware made since 2013 due to the complexity of the 216 market and difficulty to test all the older cards effectively. If you 217 have hardware supported by drm-kmod, you are strongly encouraged to use 218 that as you will get better support. 219 220 Other than KPI chasing, drm-legacy-kmod will not be updated. As outlined 221 elsewhere, the drm and drm2 modules will be eliminated from the src base 222 soon (with a limited exception for arm). Please update to the package 223 asap and report any issues to x11@freebsd.org. 224 225 Generally, anybody using the drm*-kmod packages should add 226 WITHOUT_DRM_MODULE=t and WITHOUT_DRM2_MODULE=t to avoid nasty 227 cross-threading surprises, especially with automatic driver 228 loading from X11 startup. These will become the defaults in 13-current 229 shortly. 230 23120181012: 232 The ixlv(4) driver has been renamed to iavf(4). As a consequence, 233 custom kernel and module loading configuration files must be updated 234 accordingly. Moreover, interfaces previous presented as ixlvN to the 235 system are now exposed as iavfN and network configuration files must 236 be adjusted as necessary. 237 23820181009: 239 OpenSSL has been updated to version 1.1.1. This update included 240 additional various API changes throughout the base system. It is 241 important to rebuild third-party software after upgrading. The value 242 of __FreeBSD_version has been bumped accordingly. 243 24420181006: 245 The legacy DRM modules and drivers have now been added to the loader's 246 module blacklist, in favor of loading them with kld_list in rc.conf(5). 247 The module blacklist may be overridden with the loader.conf(5) 248 'module_blacklist' variable, but loading them via rc.conf(5) is strongly 249 encouraged. 250 25120181002: 252 The cam(4) based nda(4) driver will be used over nvd(4) by default on 253 powerpc64. You may set 'options NVME_USE_NVD=1' in your kernel conf or 254 loader tunable 'hw.nvme.use_nvd=1' if you wish to use the existing 255 driver. Make sure to edit /boot/etc/kboot.conf and fstab to use the 256 nda device name. 257 25820180913: 259 Reproducible build mode is now on by default, in preparation for 260 FreeBSD 12.0. This eliminates build metadata such as the user, 261 host, and time from the kernel (and uname), unless the working tree 262 corresponds to a modified checkout from a version control system. 263 The previous behavior can be obtained by setting the /etc/src.conf 264 knob WITHOUT_REPRODUCIBLE_BUILD. 265 26620180826: 267 The Yarrow CSPRNG has been removed from the kernel as it has not been 268 supported by its designers since at least 2003. Fortuna has been the 269 default since FreeBSD-11. 270 27120180822: 272 devctl freeze/thaw have gone into the tree, the rc scripts have been 273 updated to use them and devmatch has been changed. You should update 274 kernel, userland and rc scripts all at the same time. 275 27620180818: 277 The default interpreter has been switched from 4th to Lua. 278 LOADER_DEFAULT_INTERP, documented in build(7), will override the default 279 interpreter. If you have custom FORTH code you will need to set 280 LOADER_DEFAULT_INTERP=4th (valid values are 4th, lua or simp) in 281 src.conf for the build. This will create default hard links between 282 loader and loader_4th instead of loader and loader_lua, the new default. 283 If you are using UEFI it will create the proper hard link to loader.efi. 284 285 bhyve uses userboot.so. It remains 4th-only until some issues are solved 286 regarding coexisting with multiple versions of FreeBSD are resolved. 287 28820180815: 289 ls(1) now respects the COLORTERM environment variable used in other 290 systems and software to indicate that a colored terminal is both 291 supported and desired. If ls(1) is suddenly emitting colors, they may 292 be disabled again by either removing the unwanted COLORTERM from your 293 environment, or using `ls --color=never`. The ls(1) specific CLICOLOR 294 may not be observed in a future release. 295 29620180808: 297 The default pager for most commands has been changed to "less". To 298 restore the old behavior, set PAGER="more" and MANPAGER="more -s" in 299 your environment. 300 30120180731: 302 The jedec_ts(4) driver has been removed. A superset of its functionality 303 is available in the jedec_dimm(4) driver, and the manpage for that 304 driver includes migration instructions. If you have "device jedec_ts" 305 in your kernel configuration file, it must be removed. 306 30720180730: 308 amd64/GENERIC now has EFI runtime services, EFIRT, enabled by default. 309 This should have no effect if the kernel is booted via BIOS/legacy boot. 310 EFIRT may be disabled via a loader tunable, efi.rt.disabled, if a system 311 has a buggy firmware that prevents a successful boot due to use of 312 runtime services. 313 31420180727: 315 Atmel AT91RM9200 and AT91SAM9, Cavium CNS 11xx and XScale 316 support has been removed from the tree. These ports were 317 obsolete and/or known to be broken for many years. 318 31920180723: 320 loader.efi has been augmented to participate more fully in the 321 UEFI boot manager protocol. loader.efi will now look at the 322 BootXXXX environment variable to determine if a specific kernel 323 or root partition was specified. XXXX is derived from BootCurrent. 324 efibootmgr(8) manages these standard UEFI variables. 325 32620180720: 327 zfsloader's functionality has now been folded into loader. 328 zfsloader is no longer necessary once you've updated your 329 boot blocks. For a transition period, we will install a 330 hardlink for zfsloader to loader to allow a smooth transition 331 until the boot blocks can be updated (hard link because old 332 zfs boot blocks don't understand symlinks). 333 33420180719: 335 ARM64 now have efifb support, if you want to have serial console 336 on your arm64 board when an screen is connected and the bootloader 337 setup a frame buffer for us to use, just add : 338 boot_serial=YES 339 boot_multicons=YES 340 in /boot/loader.conf 341 For Raspberry Pi 3 (RPI) users, this is needed even if you don't have 342 an screen connected as the firmware will setup a frame buffer are that 343 u-boot will expose as an EFI frame buffer. 344 34520180719: 346 New uid:gid added, ntpd:ntpd (123:123). Be sure to run mergemaster 347 or take steps to update /etc/passwd before doing installworld on 348 existing systems. Do not skip the "mergemaster -Fp" step before 349 installworld, as described in the update procedures near the bottom 350 of this document. Also, rc.d/ntpd now starts ntpd(8) as user ntpd 351 if the new mac_ntpd(4) policy is available, unless ntpd_flags or 352 the ntp config file contain options that change file/dir locations. 353 When such options (e.g., "statsdir" or "crypto") are used, ntpd can 354 still be run as non-root by setting ntpd_user=ntpd in rc.conf, after 355 taking steps to ensure that all required files/dirs are accessible 356 by the ntpd user. 357 35820180717: 359 Big endian arm support has been removed. 360 36120180711: 362 The static environment setup in kernel configs is no longer mutually 363 exclusive with the loader(8) environment by default. In order to 364 restore the previous default behavior of disabling the loader(8) 365 environment if a static environment is present, you must specify 366 loader_env.disabled=1 in the static environment. 367 36820180705: 369 The ABI of syscalls used by management tools like sockstat and 370 netstat has been broken to allow 32-bit binaries to work on 371 64-bit kernels without modification. These programs will need 372 to match the kernel in order to function. External programs may 373 require minor modifications to accommodate a change of type in 374 structures from pointers to 64-bit virtual addresses. 375 37620180702: 377 On i386 and amd64 atomics are now inlined. Out of tree modules using 378 atomics will need to be rebuilt. 379 38020180701: 381 The '%I' format in the kern.corefile sysctl limits the number of 382 core files that a process can generate to the number stored in the 383 debug.ncores sysctl. The '%I' format is replaced by the single digit 384 index. Previously, if all indexes were taken the kernel would overwrite 385 only a core file with the highest index in a filename. 386 Currently the system will create a new core file if there is a free 387 index or if all slots are taken it will overwrite the oldest one. 388 38920180630: 390 Clang, llvm, lld, lldb, compiler-rt and libc++ have been upgraded to 391 6.0.1. Please see the 20141231 entry below for information about 392 prerequisites and upgrading, if you are not already using clang 3.5.0 393 or higher. 394 39520180628: 396 r335753 introduced a new quoting method. However, etc/devd/devmatch.conf 397 needed to be changed to work with it. This change was made with r335763 398 and requires a mergemaster / etcupdate / etc to update the installed 399 file. 400 40120180612: 402 r334930 changed the interface between the NFS modules, so they all 403 need to be rebuilt. r335018 did a __FreeBSD_version bump for this. 404 40520180530: 406 As of r334391 lld is the default amd64 system linker; it is installed 407 as /usr/bin/ld. Kernel build workarounds (see 20180510 entry) are no 408 longer necessary. 409 41020180530: 411 The kernel / userland interface for devinfo changed, so you'll 412 need a new kernel and userland as a pair for it to work (rebuilding 413 lib/libdevinfo is all that's required). devinfo and devmatch will 414 not work, but everything else will when there's a mismatch. 415 41620180523: 417 The on-disk format for hwpmc callchain records has changed to include 418 threadid corresponding to a given record. This changes the field offsets 419 and thus requires that libpmcstat be rebuilt before using a kernel 420 later than r334108. 421 42220180517: 423 The vxge(4) driver has been removed. This driver was introduced into 424 HEAD one week before the Exar left the Ethernet market and is not 425 known to be used. If you have device vxge in your kernel config file 426 it must be removed. 427 42820180510: 429 The amd64 kernel now requires a ld that supports ifunc to produce a 430 working kernel, either lld or a newer binutils. lld is built by default 431 on amd64, and the 'buildkernel' target uses it automatically. However, 432 it is not the default linker, so building the kernel the traditional 433 way requires LD=ld.lld on the command line (or LD=/usr/local/bin/ld for 434 binutils port/package). lld will soon be default, and this requirement 435 will go away. 436 437 NOTE: As of r334391 lld is the default system linker on amd64, and no 438 workaround is necessary. 439 44020180508: 441 The nxge(4) driver has been removed. This driver was for PCI-X 10g 442 cards made by s2io/Neterion. The company was acquired by Exar and 443 no longer sells or supports Ethernet products. If you have device 444 nxge in your kernel config file it must be removed. 445 44620180504: 447 The tz database (tzdb) has been updated to 2018e. This version more 448 correctly models time stamps in time zones with negative DST such as 449 Europe/Dublin (from 1971 on), Europe/Prague (1946/7), and 450 Africa/Windhoek (1994/2017). This does not affect the UT offsets, only 451 time zone abbreviations and the tm_isdst flag. 452 45320180502: 454 The ixgb(4) driver has been removed. This driver was for an early and 455 uncommon legacy PCI 10GbE for a single ASIC, Intel 82597EX. Intel 456 quickly shifted to the long lived ixgbe family. If you have device 457 ixgb in your kernel config file it must be removed. 458 45920180501: 460 The lmc(4) driver has been removed. This was a WAN interface 461 card that was already reportedly rare in 2003, and had an ambiguous 462 license. If you have device lmc in your kernel config file it must 463 be removed. 464 46520180413: 466 Support for Arcnet networks has been removed. If you have device 467 arcnet or device cm in your kernel config file they must be 468 removed. 469 47020180411: 471 Support for FDDI networks has been removed. If you have device 472 fddi or device fpa in your kernel config file they must be 473 removed. 474 47520180406: 476 In addition to supporting RFC 3164 formatted messages, the 477 syslogd(8) service is now capable of parsing RFC 5424 formatted 478 log messages. The main benefit of using RFC 5424 is that clients 479 may now send log messages with timestamps containing year numbers, 480 microseconds and time zone offsets. 481 482 Similarly, the syslog(3) C library function has been altered to 483 send RFC 5424 formatted messages to the local system logging 484 daemon. On systems using syslogd(8), this change should have no 485 negative impact, as long as syslogd(8) and the C library are 486 updated at the same time. On systems using a different system 487 logging daemon, it may be necessary to make configuration 488 adjustments, depending on the software used. 489 490 When using syslog-ng, add the 'syslog-protocol' flag to local 491 input sources to enable parsing of RFC 5424 formatted messages: 492 493 source src { 494 unix-dgram("/var/run/log" flags(syslog-protocol)); 495 } 496 497 When using rsyslog, disable the 'SysSock.UseSpecialParser' option 498 of the 'imuxsock' module to let messages be processed by the 499 regular RFC 3164/5424 parsing pipeline: 500 501 module(load="imuxsock" SysSock.UseSpecialParser="off") 502 503 Do note that these changes only affect communication between local 504 applications and syslogd(8). The format that syslogd(8) uses to 505 store messages on disk or forward messages to other systems 506 remains unchanged. syslogd(8) still uses RFC 3164 for these 507 purposes. Options to customize this behaviour will be added in the 508 future. Utilities that process log files stored in /var/log are 509 thus expected to continue to function as before. 510 511 __FreeBSD_version has been incremented to 1200061 to denote this 512 change. 513 51420180328: 515 Support for token ring networks has been removed. If you 516 have "device token" in your kernel config you should remove 517 it. No device drivers supported token ring. 518 51920180323: 520 makefs was modified to be able to tag ISO9660 El Torito boot catalog 521 entries as EFI instead of overloading the i386 tag as done previously. 522 The amd64 mkisoimages.sh script used to build amd64 ISO images for 523 release was updated to use this. This may mean that makefs must be 524 updated before "make cdrom" can be run in the release directory. This 525 should be as simple as: 526 527 $ cd $SRCDIR/usr.sbin/makefs 528 $ make depend all install 529 53020180212: 531 FreeBSD boot loader enhanced with Lua scripting. It's purely opt-in for 532 now by building WITH_LOADER_LUA and WITHOUT_FORTH in /etc/src.conf. 533 Co-existence for the transition period will come shortly. Booting is a 534 complex environment and test coverage for Lua-enabled loaders has been 535 thin, so it would be prudent to assume it might not work and make 536 provisions for backup boot methods. 537 53820180211: 539 devmatch functionality has been turned on in devd. It will automatically 540 load drivers for unattached devices. This may cause unexpected drivers 541 to be loaded. Please report any problems to current@ and 542 imp@freebsd.org. 543 54420180114: 545 Clang, llvm, lld, lldb, compiler-rt and libc++ have been upgraded to 546 6.0.0. Please see the 20141231 entry below for information about 547 prerequisites and upgrading, if you are not already using clang 3.5.0 548 or higher. 549 55020180110: 551 LLVM's lld linker is now used as the FreeBSD/amd64 bootstrap linker. 552 This means it is used to link the kernel and userland libraries and 553 executables, but is not yet installed as /usr/bin/ld by default. 554 555 To revert to ld.bfd as the bootstrap linker, in /etc/src.conf set 556 WITHOUT_LLD_BOOTSTRAP=yes 557 55820180110: 559 On i386, pmtimer has been removed. Its functionality has been folded 560 into apm. It was a no-op on ACPI in current for a while now (but was 561 still needed on i386 in FreeBSD 11 and earlier). Users may need to 562 remove it from kernel config files. 563 56420180104: 565 The use of RSS hash from the network card aka flowid has been 566 disabled by default for lagg(4) as it's currently incompatible with 567 the lacp and loadbalance protocols. 568 569 This can be re-enabled by setting the following in loader.conf: 570 net.link.lagg.default_use_flowid="1" 571 57220180102: 573 The SW_WATCHDOG option is no longer necessary to enable the 574 hardclock-based software watchdog if no hardware watchdog is 575 configured. As before, SW_WATCHDOG will cause the software 576 watchdog to be enabled even if a hardware watchdog is configured. 577 57820171215: 579 r326887 fixes the issue described in the 20171214 UPDATING entry. 580 r326888 flips the switch back to building GELI support always. 581 58220171214: 583 r362593 broke ZFS + GELI support for reasons unknown. However, 584 it also broke ZFS support generally, so GELI has been turned off 585 by default as the lesser evil in r326857. If you boot off ZFS and/or 586 GELI, it might not be a good time to update. 587 58820171125: 589 PowerPC users must update loader(8) by rebuilding world before 590 installing a new kernel, as the protocol connecting them has 591 changed. Without the update, loader metadata will not be passed 592 successfully to the kernel and users will have to enter their 593 root partition at the kernel mountroot prompt to continue booting. 594 Newer versions of loader can boot old kernels without issue. 595 59620171110: 597 The LOADER_FIREWIRE_SUPPORT build variable as been renamed to 598 WITH/OUT_LOADER_FIREWIRE. LOADER_{NO_,}GELI_SUPPORT has been renamed 599 to WITH/OUT_LOADER_GELI. 600 60120171106: 602 The naive and non-compliant support of posix_fallocate(2) in ZFS 603 has been removed as of r325320. The system call now returns EINVAL 604 when used on a ZFS file. Although the new behavior complies with the 605 standard, some consumers are not prepared to cope with it. 606 One known victim is lld prior to r325420. 607 60820171102: 609 Building in a FreeBSD src checkout will automatically create object 610 directories now rather than store files in the current directory if 611 'make obj' was not ran. Calling 'make obj' is no longer necessary. 612 This feature can be disabled by setting WITHOUT_AUTO_OBJ=yes in 613 /etc/src-env.conf (not /etc/src.conf), or passing the option in the 614 environment. 615 61620171101: 617 The default MAKEOBJDIR has changed from /usr/obj/<srcdir> for native 618 builds, and /usr/obj/<arch>/<srcdir> for cross-builds, to a unified 619 /usr/obj/<srcdir>/<arch>. This behavior can be changed to the old 620 format by setting WITHOUT_UNIFIED_OBJDIR=yes in /etc/src-env.conf, 621 the environment, or with -DWITHOUT_UNIFIED_OBJDIR when building. 622 The UNIFIED_OBJDIR option is a transitional feature that will be 623 removed for 12.0 release; please migrate to the new format for any 624 tools by looking up the OBJDIR used by 'make -V .OBJDIR' means rather 625 than hardcoding paths. 626 62720171028: 628 The native-xtools target no longer installs the files by default to the 629 OBJDIR. Use the native-xtools-install target with a DESTDIR to install 630 to ${DESTDIR}/${NXTP} where NXTP defaults to /nxb-bin. 631 63220171021: 633 As part of the boot loader infrastructure cleanup, LOADER_*_SUPPORT 634 options are changing from controlling the build if defined / undefined 635 to controlling the build with explicit 'yes' or 'no' values. They will 636 shift to WITH/WITHOUT options to match other options in the system. 637 63820171010: 639 libstand has turned into a private library for sys/boot use only. 640 It is no longer supported as a public interface outside of sys/boot. 641 64220171005: 643 The arm port has split armv6 into armv6 and armv7. armv7 is now 644 a valid TARGET_ARCH/MACHINE_ARCH setting. If you have an armv7 system 645 and are running a kernel from before r324363, you will need to add 646 MACHINE_ARCH=armv7 to 'make buildworld' to do a native build. 647 64820171003: 649 When building multiple kernels using KERNCONF, non-existent KERNCONF 650 files will produce an error and buildkernel will fail. Previously 651 missing KERNCONF files silently failed giving no indication as to 652 why, only to subsequently discover during installkernel that the 653 desired kernel was never built in the first place. 654 65520170912: 656 The default serial number format for CTL LUNs has changed. This will 657 affect users who use /dev/diskid/* device nodes, or whose FibreChannel 658 or iSCSI clients care about their LUNs' serial numbers. Users who 659 require serial number stability should hardcode serial numbers in 660 /etc/ctl.conf . 661 66220170912: 663 For 32-bit arm compiled for hard-float support, soft-floating point 664 binaries now always get their shared libraries from 665 LD_SOFT_LIBRARY_PATH (in the past, this was only used if 666 /usr/libsoft also existed). Only users with a hard-float ld.so, but 667 soft-float everything else should be affected. 668 66920170826: 670 The geli password typed at boot is now hidden. To restore the previous 671 behavior, see geli(8) for configuration options. 672 67320170825: 674 Move PMTUD blackhole counters to TCPSTATS and remove them from bare 675 sysctl values. Minor nit, but requires a rebuild of both world/kernel 676 to complete. 677 67820170814: 679 "make check" behavior (made in ^/head@r295380) has been changed to 680 execute from a limited sandbox, as opposed to executing from 681 ${TESTSDIR}. 682 683 Behavioral changes: 684 - The "beforecheck" and "aftercheck" targets are now specified. 685 - ${CHECKDIR} (added in commit noted above) has been removed. 686 - Legacy behavior can be enabled by setting 687 WITHOUT_MAKE_CHECK_USE_SANDBOX in src.conf(5) or the environment. 688 689 If the limited sandbox mode is enabled, "make check" will execute 690 "make distribution", then install, execute the tests, and clean up the 691 sandbox if successful. 692 693 The "make distribution" and "make install" targets are typically run as 694 root to set appropriate permissions and ownership at installation time. 695 The end-user should set "WITH_INSTALL_AS_USER" in src.conf(5) or the 696 environment if executing "make check" with limited sandbox mode using 697 an unprivileged user. 698 69920170808: 700 Since the switch to GPT disk labels, fsck for UFS/FFS has been 701 unable to automatically find alternate superblocks. As of r322297, 702 the information needed to find alternate superblocks has been 703 moved to the end of the area reserved for the boot block. 704 Filesystems created with a newfs of this vintage or later 705 will create the recovery information. If you have a filesystem 706 created prior to this change and wish to have a recovery block 707 created for your filesystem, you can do so by running fsck in 708 foreground mode (i.e., do not use the -p or -y options). As it 709 starts, fsck will ask ``SAVE DATA TO FIND ALTERNATE SUPERBLOCKS'' 710 to which you should answer yes. 711 71220170728: 713 As of r321665, an NFSv4 server configuration that services 714 Kerberos mounts or clients that do not support the uid/gid in 715 owner/owner_group string capability, must explicitly enable 716 the nfsuserd daemon by adding nfsuserd_enable="YES" to the 717 machine's /etc/rc.conf file. 718 71920170722: 720 Clang, llvm, lldb, compiler-rt and libc++ have been upgraded to 5.0.0. 721 Please see the 20141231 entry below for information about prerequisites 722 and upgrading, if you are not already using clang 3.5.0 or higher. 723 72420170701: 725 WITHOUT_RCMDS is now the default. Set WITH_RCMDS if you need the 726 r-commands (rlogin, rsh, etc.) to be built with the base system. 727 72820170625: 729 The FreeBSD/powerpc platform now uses a 64-bit type for time_t. This is 730 a very major ABI incompatible change, so users of FreeBSD/powerpc must 731 be careful when performing source upgrades. It is best to run 732 'make installworld' from an alternate root system, either a live 733 CD/memory stick, or a temporary root partition. Additionally, all ports 734 must be recompiled. powerpc64 is largely unaffected, except in the case 735 of 32-bit compatibility. All 32-bit binaries will be affected. 736 73720170623: 738 Forward compatibility for the "ino64" project have been committed. This 739 will allow most new binaries to run on older kernels in a limited 740 fashion. This prevents many of the common foot-shooting actions in the 741 upgrade as well as the limited ability to roll back the kernel across 742 the ino64 upgrade. Complicated use cases may not work properly, though 743 enough simpler ones work to allow recovery in most situations. 744 74520170620: 746 Switch back to the BSDL dtc (Device Tree Compiler). Set WITH_GPL_DTC 747 if you require the GPL compiler. 748 74920170618: 750 The internal ABI used for communication between the NFS kernel modules 751 was changed by r320085, so __FreeBSD_version was bumped to 752 ensure all the NFS related modules are updated together. 753 75420170617: 755 The ABI of struct event was changed by extending the data 756 member to 64bit and adding ext fields. For upgrade, same 757 precautions as for the entry 20170523 "ino64" must be 758 followed. 759 76020170531: 761 The GNU roff toolchain has been removed from base. To render manpages 762 which are not supported by mandoc(1), man(1) can fallback on GNU roff 763 from ports (and recommends to install it). 764 To render roff(7) documents, consider using GNU roff from ports or the 765 heirloom doctools roff toolchain from ports via pkg install groff or 766 via pkg install heirloom-doctools. 767 76820170524: 769 The ath(4) and ath_hal(4) modules now build piecemeal to allow for 770 smaller runtime footprint builds. This is useful for embedded systems 771 which only require one chipset support. 772 773 If you load it as a module, make sure this is in /boot/loader.conf: 774 775 if_ath_load="YES" 776 777 This will load the HAL, all chip/RF backends and if_ath_pci. 778 If you have if_ath_pci in /boot/loader.conf, ensure it is after 779 if_ath or it will not load any HAL chipset support. 780 781 If you want to selectively load things (eg on ye cheape ARM/MIPS 782 platforms where RAM is at a premium) you should: 783 784 * load ath_hal 785 * load the chip modules in question 786 * load ath_rate, ath_dfs 787 * load ath_main 788 * load if_ath_pci and/or if_ath_ahb depending upon your particular 789 bus bind type - this is where probe/attach is done. 790 791 For further comments/feedback, poke adrian@ . 792 79320170523: 794 The "ino64" 64-bit inode project has been committed, which extends 795 a number of types to 64 bits. Upgrading in place requires care and 796 adherence to the documented upgrade procedure. 797 798 If using a custom kernel configuration ensure that the 799 COMPAT_FREEBSD11 option is included (as during the upgrade the 800 system will be running the ino64 kernel with the existing world). 801 802 For the safest in-place upgrade begin by removing previous build 803 artifacts via "rm -rf /usr/obj/*". Then, carefully follow the full 804 procedure documented below under the heading "To rebuild everything and 805 install it on the current system." Specifically, a reboot is required 806 after installing the new kernel before installing world. While an 807 installworld normally works by accident from multiuser after rebooting 808 the proper kernel, there are many cases where this will fail across this 809 upgrade and installworld from single user is required. 810 81120170424: 812 The NATM framework including the en(4), fatm(4), hatm(4), and 813 patm(4) devices has been removed. Consumers should plan a 814 migration before the end-of-life date for FreeBSD 11. 815 81620170420: 817 GNU diff has been replaced by a BSD licensed diff. Some features of GNU 818 diff has not been implemented, if those are needed a newer version of 819 GNU diff is available via the diffutils package under the gdiff name. 820 82120170413: 822 As of r316810 for ipfilter, keep frags is no longer assumed when 823 keep state is specified in a rule. r316810 aligns ipfilter with 824 documentation in man pages separating keep frags from keep state. 825 This allows keep state to be specified without forcing keep frags 826 and allows keep frags to be specified independently of keep state. 827 To maintain previous behaviour, also specify keep frags with 828 keep state (as documented in ipf.conf.5). 829 83020170407: 831 arm64 builds now use the base system LLD 4.0.0 linker by default, 832 instead of requiring that the aarch64-binutils port or package be 833 installed. To continue using aarch64-binutils, set 834 CROSS_BINUTILS_PREFIX=/usr/local/aarch64-freebsd/bin . 835 83620170405: 837 The UDP optimization in entry 20160818 that added the sysctl 838 net.inet.udp.require_l2_bcast has been reverted. L2 broadcast 839 packets will no longer be treated as L3 broadcast packets. 840 84120170331: 842 Binds and sends to the loopback addresses, IPv6 and IPv4, will now 843 use any explicitly assigned loopback address available in the jail 844 instead of using the first assigned address of the jail. 845 84620170329: 847 The ctl.ko module no longer implements the iSCSI target frontend: 848 cfiscsi.ko does instead. 849 850 If building cfiscsi.ko as a kernel module, the module can be loaded 851 via one of the following methods: 852 - `cfiscsi_load="YES"` in loader.conf(5). 853 - Add `cfiscsi` to `$kld_list` in rc.conf(5). 854 - ctladm(8)/ctld(8), when compiled with iSCSI support 855 (`WITH_ISCSI=yes` in src.conf(5)) 856 857 Please see cfiscsi(4) for more details. 858 85920170316: 860 The mmcsd.ko module now additionally depends on geom_flashmap.ko. 861 Also, mmc.ko and mmcsd.ko need to be a matching pair built from the 862 same source (previously, the dependency of mmcsd.ko on mmc.ko was 863 missing, but mmcsd.ko now will refuse to load if it is incompatible 864 with mmc.ko). 865 86620170315: 867 The syntax of ipfw(8) named states was changed to avoid ambiguity. 868 If you have used named states in the firewall rules, you need to modify 869 them after installworld and before rebooting. Now named states must 870 be prefixed with colon. 871 87220170311: 873 The old drm (sys/dev/drm/) drivers for i915 and radeon have been 874 removed as the userland we provide cannot use them. The KMS version 875 (sys/dev/drm2) supports the same hardware. 876 87720170302: 878 Clang, llvm, lldb, compiler-rt and libc++ have been upgraded to 4.0.0. 879 Please see the 20141231 entry below for information about prerequisites 880 and upgrading, if you are not already using clang 3.5.0 or higher. 881 88220170221: 883 The code that provides support for ZFS .zfs/ directory functionality 884 has been reimplemented. It's not possible now to create a snapshot 885 by mkdir under .zfs/snapshot/. That should be the only user visible 886 change. 887 88820170216: 889 EISA bus support has been removed. The WITH_EISA option is no longer 890 valid. 891 89220170215: 893 MCA bus support has been removed. 894 89520170127: 896 The WITH_LLD_AS_LD / WITHOUT_LLD_AS_LD build knobs have been renamed 897 WITH_LLD_IS_LD / WITHOUT_LLD_IS_LD, for consistency with CLANG_IS_CC. 898 89920170112: 900 The EM_MULTIQUEUE kernel configuration option is deprecated now that 901 the em(4) driver conforms to iflib specifications. 902 90320170109: 904 The igb(4), em(4) and lem(4) ethernet drivers are now implemented via 905 IFLIB. If you have a custom kernel configuration that excludes em(4) 906 but you use igb(4), you need to re-add em(4) to your custom 907 configuration. 908 90920161217: 910 Clang, llvm, lldb, compiler-rt and libc++ have been upgraded to 3.9.1. 911 Please see the 20141231 entry below for information about prerequisites 912 and upgrading, if you are not already using clang 3.5.0 or higher. 913 91420161124: 915 Clang, llvm, lldb, compiler-rt and libc++ have been upgraded to 3.9.0. 916 Please see the 20141231 entry below for information about prerequisites 917 and upgrading, if you are not already using clang 3.5.0 or higher. 918 91920161119: 920 The layout of the pmap structure has changed for powerpc to put the pmap 921 statistics at the front for all CPU variations. libkvm(3) and all tools 922 that link against it need to be recompiled. 923 92420161030: 925 isl(4) and cyapa(4) drivers now require a new driver, 926 chromebook_platform(4), to work properly on Chromebook-class hardware. 927 On other types of hardware the drivers may need to be configured using 928 device hints. Please see the corresponding manual pages for details. 929 93020161017: 931 The urtwn(4) driver was merged into rtwn(4) and now consists of 932 rtwn(4) main module + rtwn_usb(4) and rtwn_pci(4) bus-specific 933 parts. 934 Also, firmware for RTL8188CE was renamed due to possible name 935 conflict (rtwnrtl8192cU(B) -> rtwnrtl8192cE(B)) 936 93720161015: 938 GNU rcs has been removed from base. It is available as packages: 939 - rcs: Latest GPLv3 GNU rcs version. 940 - rcs57: Copy of the latest version of GNU rcs (GPLv2) before it was 941 removed from base. 942 94320161008: 944 Use of the cc_cdg, cc_chd, cc_hd, or cc_vegas congestion control 945 modules now requires that the kernel configuration contain the 946 TCP_HHOOK option. (This option is included in the GENERIC kernel.) 947 94820161003: 949 The WITHOUT_ELFCOPY_AS_OBJCOPY src.conf(5) knob has been retired. 950 ELF Tool Chain's elfcopy is always installed as /usr/bin/objcopy. 951 95220160924: 953 Relocatable object files with the extension of .So have been renamed 954 to use an extension of .pico instead. The purpose of this change is 955 to avoid a name clash with shared libraries on case-insensitive file 956 systems. On those file systems, foo.So is the same file as foo.so. 957 95820160918: 959 GNU rcs has been turned off by default. It can (temporarily) be built 960 again by adding WITH_RCS knob in src.conf. 961 Otherwise, GNU rcs is available from packages: 962 - rcs: Latest GPLv3 GNU rcs version. 963 - rcs57: Copy of the latest version of GNU rcs (GPLv2) from base. 964 96520160918: 966 The backup_uses_rcs functionality has been removed from rc.subr. 967 96820160908: 969 The queue(3) debugging macro, QUEUE_MACRO_DEBUG, has been split into 970 two separate components, QUEUE_MACRO_DEBUG_TRACE and 971 QUEUE_MACRO_DEBUG_TRASH. Define both for the original 972 QUEUE_MACRO_DEBUG behavior. 973 97420160824: 975 r304787 changed some ioctl interfaces between the iSCSI userspace 976 programs and the kernel. ctladm, ctld, iscsictl, and iscsid must be 977 rebuilt to work with new kernels. __FreeBSD_version has been bumped 978 to 1200005. 979 98020160818: 981 The UDP receive code has been updated to only treat incoming UDP 982 packets that were addressed to an L2 broadcast address as L3 983 broadcast packets. It is not expected that this will affect any 984 standards-conforming UDP application. The new behaviour can be 985 disabled by setting the sysctl net.inet.udp.require_l2_bcast to 986 0. 987 98820160818: 989 Remove the openbsd_poll system call. 990 __FreeBSD_version has been bumped because of this. 991 99220160708: 993 The stable/11 branch has been created from head@r302406. 994 99520160622: 996 The libc stub for the pipe(2) system call has been replaced with 997 a wrapper that calls the pipe2(2) system call and the pipe(2) 998 system call is now only implemented by the kernels that include 999 "options COMPAT_FREEBSD10" in their config file (this is the 1000 default). Users should ensure that this option is enabled in 1001 their kernel or upgrade userspace to r302092 before upgrading their 1002 kernel. 1003 100420160527: 1005 CAM will now strip leading spaces from SCSI disks' serial numbers. 1006 This will affect users who create UFS filesystems on SCSI disks using 1007 those disk's diskid device nodes. For example, if /etc/fstab 1008 previously contained a line like 1009 "/dev/diskid/DISK-%20%20%20%20%20%20%20ABCDEFG0123456", you should 1010 change it to "/dev/diskid/DISK-ABCDEFG0123456". Users of geom 1011 transforms like gmirror may also be affected. ZFS users should 1012 generally be fine. 1013 101420160523: 1015 The bitstring(3) API has been updated with new functionality and 1016 improved performance. But it is binary-incompatible with the old API. 1017 Objects built with the new headers may not be linked against objects 1018 built with the old headers. 1019 102020160520: 1021 The brk and sbrk functions have been removed from libc on arm64. 1022 Binutils from ports has been updated to not link to these 1023 functions and should be updated to the latest version before 1024 installing a new libc. 1025 102620160517: 1027 The armv6 port now defaults to hard float ABI. Limited support 1028 for running both hardfloat and soft float on the same system 1029 is available using the libraries installed with -DWITH_LIBSOFT. 1030 This has only been tested as an upgrade path for installworld 1031 and packages may fail or need manual intervention to run. New 1032 packages will be needed. 1033 1034 To update an existing self-hosted armv6hf system, you must add 1035 TARGET_ARCH=armv6 on the make command line for both the build 1036 and the install steps. 1037 103820160510: 1039 Kernel modules compiled outside of a kernel build now default to 1040 installing to /boot/modules instead of /boot/kernel. Many kernel 1041 modules built this way (such as those in ports) already overrode 1042 KMODDIR explicitly to install into /boot/modules. However, 1043 manually building and installing a module from /sys/modules will 1044 now install to /boot/modules instead of /boot/kernel. 1045 104620160414: 1047 The CAM I/O scheduler has been committed to the kernel. There should be 1048 no user visible impact. This does enable NCQ Trim on ada SSDs. While the 1049 list of known rogues that claim support for this but actually corrupt 1050 data is believed to be complete, be on the lookout for data 1051 corruption. The known rogue list is believed to be complete: 1052 1053 o Crucial MX100, M550 drives with MU01 firmware. 1054 o Micron M510 and M550 drives with MU01 firmware. 1055 o Micron M500 prior to MU07 firmware 1056 o Samsung 830, 840, and 850 all firmwares 1057 o FCCT M500 all firmwares 1058 1059 Crucial has firmware http://www.crucial.com/usa/en/support-ssd-firmware 1060 with working NCQ TRIM. For Micron branded drives, see your sales rep for 1061 updated firmware. Black listed drives will work correctly because these 1062 drives work correctly so long as no NCQ TRIMs are sent to them. Given 1063 this list is the same as found in Linux, it's believed there are no 1064 other rogues in the market place. All other models from the above 1065 vendors work. 1066 1067 To be safe, if you are at all concerned, you can quirk each of your 1068 drives to prevent NCQ from being sent by setting: 1069 kern.cam.ada.X.quirks="0x2" 1070 in loader.conf. If the drive requires the 4k sector quirk, set the 1071 quirks entry to 0x3. 1072 107320160330: 1074 The FAST_DEPEND build option has been removed and its functionality is 1075 now the one true way. The old mkdep(1) style of 'make depend' has 1076 been removed. See 20160311 for further details. 1077 107820160317: 1079 Resource range types have grown from unsigned long to uintmax_t. All 1080 drivers, and anything using libdevinfo, need to be recompiled. 1081 108220160311: 1083 WITH_FAST_DEPEND is now enabled by default for in-tree and out-of-tree 1084 builds. It no longer runs mkdep(1) during 'make depend', and the 1085 'make depend' stage can safely be skipped now as it is auto ran 1086 when building 'make all' and will generate all SRCS and DPSRCS before 1087 building anything else. Dependencies are gathered at compile time with 1088 -MF flags kept in separate .depend files per object file. Users should 1089 run 'make cleandepend' once if using -DNO_CLEAN to clean out older 1090 stale .depend files. 1091 109220160306: 1093 On amd64, clang 3.8.0 can now insert sections of type AMD64_UNWIND into 1094 kernel modules. Therefore, if you load any kernel modules at boot time, 1095 please install the boot loaders after you install the kernel, but before 1096 rebooting, e.g.: 1097 1098 make buildworld 1099 make buildkernel KERNCONF=YOUR_KERNEL_HERE 1100 make installkernel KERNCONF=YOUR_KERNEL_HERE 1101 make -C sys/boot install 1102 <reboot in single user> 1103 1104 Then follow the usual steps, described in the General Notes section, 1105 below. 1106 110720160305: 1108 Clang, llvm, lldb and compiler-rt have been upgraded to 3.8.0. Please 1109 see the 20141231 entry below for information about prerequisites and 1110 upgrading, if you are not already using clang 3.5.0 or higher. 1111 111220160301: 1113 The AIO subsystem is now a standard part of the kernel. The 1114 VFS_AIO kernel option and aio.ko kernel module have been removed. 1115 Due to stability concerns, asynchronous I/O requests are only 1116 permitted on sockets and raw disks by default. To enable 1117 asynchronous I/O requests on all file types, set the 1118 vfs.aio.enable_unsafe sysctl to a non-zero value. 1119 112020160226: 1121 The ELF object manipulation tool objcopy is now provided by the 1122 ELF Tool Chain project rather than by GNU binutils. It should be a 1123 drop-in replacement, with the addition of arm64 support. The 1124 (temporary) src.conf knob WITHOUT_ELFCOPY_AS_OBJCOPY knob may be set 1125 to obtain the GNU version if necessary. 1126 112720160129: 1128 Building ZFS pools on top of zvols is prohibited by default. That 1129 feature has never worked safely; it's always been prone to deadlocks. 1130 Using a zvol as the backing store for a VM guest's virtual disk will 1131 still work, even if the guest is using ZFS. Legacy behavior can be 1132 restored by setting vfs.zfs.vol.recursive=1. 1133 113420160119: 1135 The NONE and HPN patches has been removed from OpenSSH. They are 1136 still available in the security/openssh-portable port. 1137 113820160113: 1139 With the addition of ypldap(8), a new _ypldap user is now required 1140 during installworld. "mergemaster -p" can be used to add the user 1141 prior to installworld, as documented in the handbook. 1142 114320151216: 1144 The tftp loader (pxeboot) now uses the option root-path directive. As a 1145 consequence it no longer looks for a pxeboot.4th file on the tftp 1146 server. Instead it uses the regular /boot infrastructure as with the 1147 other loaders. 1148 114920151211: 1150 The code to start recording plug and play data into the modules has 1151 been committed. While the old tools will properly build a new kernel, 1152 a number of warnings about "unknown metadata record 4" will be produced 1153 for an older kldxref. To avoid such warnings, make sure to rebuild 1154 the kernel toolchain (or world). Make sure that you have r292078 or 1155 later when trying to build 292077 or later before rebuilding. 1156 115720151207: 1158 Debug data files are now built by default with 'make buildworld' and 1159 installed with 'make installworld'. This facilitates debugging but 1160 requires more disk space both during the build and for the installed 1161 world. Debug files may be disabled by setting WITHOUT_DEBUG_FILES=yes 1162 in src.conf(5). 1163 116420151130: 1165 r291527 changed the internal interface between the nfsd.ko and 1166 nfscommon.ko modules. As such, they must both be upgraded to-gether. 1167 __FreeBSD_version has been bumped because of this. 1168 116920151108: 1170 Add support for unicode collation strings leads to a change of 1171 order of files listed by ls(1) for example. To get back to the old 1172 behaviour, set LC_COLLATE environment variable to "C". 1173 1174 Databases administrators will need to reindex their databases given 1175 collation results will be different. 1176 1177 Due to a bug in install(1) it is recommended to remove the ancient 1178 locales before running make installworld. 1179 1180 rm -rf /usr/share/locale/* 1181 118220151030: 1183 The OpenSSL has been upgraded to 1.0.2d. Any binaries requiring 1184 libcrypto.so.7 or libssl.so.7 must be recompiled. 1185 118620151020: 1187 Qlogic 24xx/25xx firmware images were updated from 5.5.0 to 7.3.0. 1188 Kernel modules isp_2400_multi and isp_2500_multi were removed and 1189 should be replaced with isp_2400 and isp_2500 modules respectively. 1190 119120151017: 1192 The build previously allowed using 'make -n' to not recurse into 1193 sub-directories while showing what commands would be executed, and 1194 'make -n -n' to recursively show commands. Now 'make -n' will recurse 1195 and 'make -N' will not. 1196 119720151012: 1198 If you specify SENDMAIL_MC or SENDMAIL_CF in make.conf, mergemaster 1199 and etcupdate will now use this file. A custom sendmail.cf is now 1200 updated via this mechanism rather than via installworld. If you had 1201 excluded sendmail.cf in mergemaster.rc or etcupdate.conf, you may 1202 want to remove the exclusion or change it to "always install". 1203 /etc/mail/sendmail.cf is now managed the same way regardless of 1204 whether SENDMAIL_MC/SENDMAIL_CF is used. If you are not using 1205 SENDMAIL_MC/SENDMAIL_CF there should be no change in behavior. 1206 120720151011: 1208 Compatibility shims for legacy ATA device names have been removed. 1209 It includes ATA_STATIC_ID kernel option, kern.cam.ada.legacy_aliases 1210 and kern.geom.raid.legacy_aliases loader tunables, kern.devalias.* 1211 environment variables, /dev/ad* and /dev/ar* symbolic links. 1212 121320151006: 1214 Clang, llvm, lldb, compiler-rt and libc++ have been upgraded to 3.7.0. 1215 Please see the 20141231 entry below for information about prerequisites 1216 and upgrading, if you are not already using clang 3.5.0 or higher. 1217 121820150924: 1219 Kernel debug files have been moved to /usr/lib/debug/boot/kernel/, 1220 and renamed from .symbols to .debug. This reduces the size requirements 1221 on the boot partition or file system and provides consistency with 1222 userland debug files. 1223 1224 When using the supported kernel installation method the 1225 /usr/lib/debug/boot/kernel directory will be renamed (to kernel.old) 1226 as is done with /boot/kernel. 1227 1228 Developers wishing to maintain the historical behavior of installing 1229 debug files in /boot/kernel/ can set KERN_DEBUGDIR="" in src.conf(5). 1230 123120150827: 1232 The wireless drivers had undergone changes that remove the 'parent 1233 interface' from the ifconfig -l output. The rc.d network scripts 1234 used to check presence of a parent interface in the list, so old 1235 scripts would fail to start wireless networking. Thus, etcupdate(3) 1236 or mergemaster(8) run is required after kernel update, to update your 1237 rc.d scripts in /etc. 1238 123920150827: 1240 pf no longer supports 'scrub fragment crop' or 'scrub fragment drop-ovl' 1241 These configurations are now automatically interpreted as 1242 'scrub fragment reassemble'. 1243 124420150817: 1245 Kernel-loadable modules for the random(4) device are back. To use 1246 them, the kernel must have 1247 1248 device random 1249 options RANDOM_LOADABLE 1250 1251 kldload(8) can then be used to load random_fortuna.ko 1252 or random_yarrow.ko. Please note that due to the indirect 1253 function calls that the loadable modules need to provide, 1254 the build-in variants will be slightly more efficient. 1255 1256 The random(4) kernel option RANDOM_DUMMY has been retired due to 1257 unpopularity. It was not all that useful anyway. 1258 125920150813: 1260 The WITHOUT_ELFTOOLCHAIN_TOOLS src.conf(5) knob has been retired. 1261 Control over building the ELF Tool Chain tools is now provided by 1262 the WITHOUT_TOOLCHAIN knob. 1263 126420150810: 1265 The polarity of Pulse Per Second (PPS) capture events with the 1266 uart(4) driver has been corrected. Prior to this change the PPS 1267 "assert" event corresponded to the trailing edge of a positive PPS 1268 pulse and the "clear" event was the leading edge of the next pulse. 1269 1270 As the width of a PPS pulse in a typical GPS receiver is on the 1271 order of 1 millisecond, most users will not notice any significant 1272 difference with this change. 1273 1274 Anyone who has compensated for the historical polarity reversal by 1275 configuring a negative offset equal to the pulse width will need to 1276 remove that workaround. 1277 127820150809: 1279 The default group assigned to /dev/dri entries has been changed 1280 from 'wheel' to 'video' with the id of '44'. If you want to have 1281 access to the dri devices please add yourself to the video group 1282 with: 1283 1284 # pw groupmod video -m $USER 1285 128620150806: 1287 The menu.rc and loader.rc files will now be replaced during 1288 upgrades. Please migrate local changes to menu.rc.local and 1289 loader.rc.local instead. 1290 129120150805: 1292 GNU Binutils versions of addr2line, c++filt, nm, readelf, size, 1293 strings and strip have been removed. The src.conf(5) knob 1294 WITHOUT_ELFTOOLCHAIN_TOOLS no longer provides the binutils tools. 1295 129620150728: 1297 As ZFS requires more kernel stack pages than is the default on some 1298 architectures e.g. i386, it now warns if KSTACK_PAGES is less than 1299 ZFS_MIN_KSTACK_PAGES (which is 4 at the time of writing). 1300 1301 Please consider using 'options KSTACK_PAGES=X' where X is greater 1302 than or equal to ZFS_MIN_KSTACK_PAGES i.e. 4 in such configurations. 1303 130420150706: 1305 sendmail has been updated to 8.15.2. Starting with FreeBSD 11.0 1306 and sendmail 8.15, sendmail uses uncompressed IPv6 addresses by 1307 default, i.e., they will not contain "::". For example, instead 1308 of ::1, it will be 0:0:0:0:0:0:0:1. This permits a zero subnet 1309 to have a more specific match, such as different map entries for 1310 IPv6:0:0 vs IPv6:0. This change requires that configuration 1311 data (including maps, files, classes, custom ruleset, etc.) must 1312 use the same format, so make certain such configuration data is 1313 upgrading. As a very simple check search for patterns like 1314 'IPv6:[0-9a-fA-F:]*::' and 'IPv6::'. To return to the old 1315 behavior, set the m4 option confUSE_COMPRESSED_IPV6_ADDRESSES or 1316 the cf option UseCompressedIPv6Addresses. 1317 131820150630: 1319 The default kernel entropy-processing algorithm is now 1320 Fortuna, replacing Yarrow. 1321 1322 Assuming you have 'device random' in your kernel config 1323 file, the configurations allow a kernel option to override 1324 this default. You may choose *ONE* of: 1325 1326 options RANDOM_YARROW # Legacy /dev/random algorithm. 1327 options RANDOM_DUMMY # Blocking-only driver. 1328 1329 If you have neither, you get Fortuna. For most people, 1330 read no further, Fortuna will give a /dev/random that works 1331 like it always used to, and the difference will be irrelevant. 1332 1333 If you remove 'device random', you get *NO* kernel-processed 1334 entropy at all. This may be acceptable to folks building 1335 embedded systems, but has complications. Carry on reading, 1336 and it is assumed you know what you need. 1337 1338 *PLEASE* read random(4) and random(9) if you are in the 1339 habit of tweaking kernel configs, and/or if you are a member 1340 of the embedded community, wanting specific and not-usual 1341 behaviour from your security subsystems. 1342 1343 NOTE!! If you use RANDOM_DUMMY and/or have no 'device 1344 random', you will NOT have a functioning /dev/random, and 1345 many cryptographic features will not work, including SSH. 1346 You may also find strange behaviour from the random(3) set 1347 of library functions, in particular sranddev(3), srandomdev(3) 1348 and arc4random(3). The reason for this is that the KERN_ARND 1349 sysctl only returns entropy if it thinks it has some to 1350 share, and with RANDOM_DUMMY or no 'device random' this 1351 will never happen. 1352 135320150623: 1354 An additional fix for the issue described in the 20150614 sendmail 1355 entry below has been committed in revision 284717. 1356 135720150616: 1358 FreeBSD's old make (fmake) has been removed from the system. It is 1359 available as the devel/fmake port or via pkg install fmake. 1360 136120150615: 1362 The fix for the issue described in the 20150614 sendmail entry 1363 below has been committed in revision 284436. The work 1364 around described in that entry is no longer needed unless the 1365 default setting is overridden by a confDH_PARAMETERS configuration 1366 setting of '5' or pointing to a 512 bit DH parameter file. 1367 136820150614: 1369 ALLOW_DEPRECATED_ATF_TOOLS/ATFFILE support has been removed from 1370 atf.test.mk (included from bsd.test.mk). Please upgrade devel/atf 1371 and devel/kyua to version 0.20+ and adjust any calling code to work 1372 with Kyuafile and kyua. 1373 137420150614: 1375 The import of openssl to address the FreeBSD-SA-15:10.openssl 1376 security advisory includes a change which rejects handshakes 1377 with DH parameters below 768 bits. sendmail releases prior 1378 to 8.15.2 (not yet released), defaulted to a 512 bit 1379 DH parameter setting for client connections. To work around 1380 this interoperability, sendmail can be configured to use a 1381 2048 bit DH parameter by: 1382 1383 1. Edit /etc/mail/`hostname`.mc 1384 2. If a setting for confDH_PARAMETERS does not exist or 1385 exists and is set to a string beginning with '5', 1386 replace it with '2'. 1387 3. If a setting for confDH_PARAMETERS exists and is set to 1388 a file path, create a new file with: 1389 openssl dhparam -out /path/to/file 2048 1390 4. Rebuild the .cf file: 1391 cd /etc/mail/; make; make install 1392 5. Restart sendmail: 1393 cd /etc/mail/; make restart 1394 1395 A sendmail patch is coming, at which time this file will be 1396 updated. 1397 139820150604: 1399 Generation of legacy formatted entries have been disabled by default 1400 in pwd_mkdb(8), as all base system consumers of the legacy formatted 1401 entries were converted to use the new format by default when the new, 1402 machine independent format have been added and supported since FreeBSD 1403 5.x. 1404 1405 Please see the pwd_mkdb(8) manual page for further details. 1406 140720150525: 1408 Clang and llvm have been upgraded to 3.6.1 release. Please see the 1409 20141231 entry below for information about prerequisites and upgrading, 1410 if you are not already using 3.5.0 or higher. 1411 141220150521: 1413 TI platform code switched to using vendor DTS files and this update 1414 may break existing systems running on Beaglebone, Beaglebone Black, 1415 and Pandaboard: 1416 1417 - dtb files should be regenerated/reinstalled. Filenames are the 1418 same but content is different now 1419 - GPIO addressing was changed, now each GPIO bank (32 pins per bank) 1420 has its own /dev/gpiocX device, e.g. pin 121 on /dev/gpioc0 in old 1421 addressing scheme is now pin 25 on /dev/gpioc3. 1422 - Pandaboard: /etc/ttys should be updated, serial console device is 1423 now /dev/ttyu2, not /dev/ttyu0 1424 142520150501: 1426 soelim(1) from gnu/usr.bin/groff has been replaced by usr.bin/soelim. 1427 If you need the GNU extension from groff soelim(1), install groff 1428 from package: pkg install groff, or via ports: textproc/groff. 1429 143020150423: 1431 chmod, chflags, chown and chgrp now affect symlinks in -R mode as 1432 defined in symlink(7); previously symlinks were silently ignored. 1433 143420150415: 1435 The const qualifier has been removed from iconv(3) to comply with 1436 POSIX. The ports tree is aware of this from r384038 onwards. 1437 143820150416: 1439 Libraries specified by LIBADD in Makefiles must have a corresponding 1440 DPADD_<lib> variable to ensure correct dependencies. This is now 1441 enforced in src.libnames.mk. 1442 144320150324: 1444 From legacy ata(4) driver was removed support for SATA controllers 1445 supported by more functional drivers ahci(4), siis(4) and mvs(4). 1446 Kernel modules ataahci and ataadaptec were removed completely, 1447 replaced by ahci and mvs modules respectively. 1448 144920150315: 1450 Clang, llvm and lldb have been upgraded to 3.6.0 release. Please see 1451 the 20141231 entry below for information about prerequisites and 1452 upgrading, if you are not already using 3.5.0 or higher. 1453 145420150307: 1455 The 32-bit PowerPC kernel has been changed to a position-independent 1456 executable. This can only be booted with a version of loader(8) 1457 newer than January 31, 2015, so make sure to update both world and 1458 kernel before rebooting. 1459 146020150217: 1461 If you are running a -CURRENT kernel since r273872 (Oct 30th, 2014), 1462 but before r278950, the RNG was not seeded properly. Immediately 1463 upgrade the kernel to r278950 or later and regenerate any keys (e.g. 1464 ssh keys or openssl keys) that were generated w/ a kernel from that 1465 range. This does not affect programs that directly used /dev/random 1466 or /dev/urandom. All userland uses of arc4random(3) are affected. 1467 146820150210: 1469 The autofs(4) ABI was changed in order to restore binary compatibility 1470 with 10.1-RELEASE. The automountd(8) daemon needs to be rebuilt to work 1471 with the new kernel. 1472 147320150131: 1474 The powerpc64 kernel has been changed to a position-independent 1475 executable. This can only be booted with a new version of loader(8), 1476 so make sure to update both world and kernel before rebooting. 1477 147820150118: 1479 Clang and llvm have been upgraded to 3.5.1 release. This is a bugfix 1480 only release, no new features have been added. Please see the 20141231 1481 entry below for information about prerequisites and upgrading, if you 1482 are not already using 3.5.0. 1483 148420150107: 1485 ELF tools addr2line, elfcopy (strip), nm, size, and strings are now 1486 taken from the ELF Tool Chain project rather than GNU binutils. They 1487 should be drop-in replacements, with the addition of arm64 support. 1488 The WITHOUT_ELFTOOLCHAIN_TOOLS= knob may be used to obtain the 1489 binutils tools, if necessary. See 20150805 for updated information. 1490 149120150105: 1492 The default Unbound configuration now enables remote control 1493 using a local socket. Users who have already enabled the 1494 local_unbound service should regenerate their configuration 1495 by running "service local_unbound setup" as root. 1496 149720150102: 1498 The GNU texinfo and GNU info pages have been removed. 1499 To be able to view GNU info pages please install texinfo from ports. 1500 150120141231: 1502 Clang, llvm and lldb have been upgraded to 3.5.0 release. 1503 1504 As of this release, a prerequisite for building clang, llvm and lldb is 1505 a C++11 capable compiler and C++11 standard library. This means that to 1506 be able to successfully build the cross-tools stage of buildworld, with 1507 clang as the bootstrap compiler, your system compiler or cross compiler 1508 should either be clang 3.3 or later, or gcc 4.8 or later, and your 1509 system C++ library should be libc++, or libdstdc++ from gcc 4.8 or 1510 later. 1511 1512 On any standard FreeBSD 10.x or 11.x installation, where clang and 1513 libc++ are on by default (that is, on x86 or arm), this should work out 1514 of the box. 1515 1516 On 9.x installations where clang is enabled by default, e.g. on x86 and 1517 powerpc, libc++ will not be enabled by default, so libc++ should be 1518 built (with clang) and installed first. If both clang and libc++ are 1519 missing, build clang first, then use it to build libc++. 1520 1521 On 8.x and earlier installations, upgrade to 9.x first, and then follow 1522 the instructions for 9.x above. 1523 1524 Sparc64 and mips users are unaffected, as they still use gcc 4.2.1 by 1525 default, and do not build clang. 1526 1527 Many embedded systems are resource constrained, and will not be able to 1528 build clang in a reasonable time, or in some cases at all. In those 1529 cases, cross building bootable systems on amd64 is a workaround. 1530 1531 This new version of clang introduces a number of new warnings, of which 1532 the following are most likely to appear: 1533 1534 -Wabsolute-value 1535 1536 This warns in two cases, for both C and C++: 1537 * When the code is trying to take the absolute value of an unsigned 1538 quantity, which is effectively a no-op, and almost never what was 1539 intended. The code should be fixed, if at all possible. If you are 1540 sure that the unsigned quantity can be safely cast to signed, without 1541 loss of information or undefined behavior, you can add an explicit 1542 cast, or disable the warning. 1543 1544 * When the code is trying to take an absolute value, but the called 1545 abs() variant is for the wrong type, which can lead to truncation. 1546 If you want to disable the warning instead of fixing the code, please 1547 make sure that truncation will not occur, or it might lead to unwanted 1548 side-effects. 1549 1550 -Wtautological-undefined-compare and 1551 -Wundefined-bool-conversion 1552 1553 These warn when C++ code is trying to compare 'this' against NULL, while 1554 'this' should never be NULL in well-defined C++ code. However, there is 1555 some legacy (pre C++11) code out there, which actively abuses this 1556 feature, which was less strictly defined in previous C++ versions. 1557 1558 Squid and openjdk do this, for example. The warning can be turned off 1559 for C++98 and earlier, but compiling the code in C++11 mode might result 1560 in unexpected behavior; for example, the parts of the program that are 1561 unreachable could be optimized away. 1562 156320141222: 1564 The old NFS client and server (kernel options NFSCLIENT, NFSSERVER) 1565 kernel sources have been removed. The .h files remain, since some 1566 utilities include them. This will need to be fixed later. 1567 If "mount -t oldnfs ..." is attempted, it will fail. 1568 If the "-o" option on mountd(8), nfsd(8) or nfsstat(1) is used, 1569 the utilities will report errors. 1570 157120141121: 1572 The handling of LOCAL_LIB_DIRS has been altered to skip addition of 1573 directories to top level SUBDIR variable when their parent 1574 directory is included in LOCAL_DIRS. Users with build systems with 1575 such hierarchies and without SUBDIR entries in the parent 1576 directory Makefiles should add them or add the directories to 1577 LOCAL_DIRS. 1578 157920141109: 1580 faith(4) and faithd(8) have been removed from the base system. Faith 1581 has been obsolete for a very long time. 1582 158320141104: 1584 vt(4), the new console driver, is enabled by default. It brings 1585 support for Unicode and double-width characters, as well as 1586 support for UEFI and integration with the KMS kernel video 1587 drivers. 1588 1589 You may need to update your console settings in /etc/rc.conf, 1590 most probably the keymap. During boot, /etc/rc.d/syscons will 1591 indicate what you need to do. 1592 1593 vt(4) still has issues and lacks some features compared to 1594 syscons(4). See the wiki for up-to-date information: 1595 https://wiki.freebsd.org/Newcons 1596 1597 If you want to keep using syscons(4), you can do so by adding 1598 the following line to /boot/loader.conf: 1599 kern.vty=sc 1600 160120141102: 1602 pjdfstest has been integrated into kyua as an opt-in test suite. 1603 Please see share/doc/pjdfstest/README for more details on how to 1604 execute it. 1605 160620141009: 1607 gperf has been removed from the base system for architectures 1608 that use clang. Ports that require gperf will obtain it from the 1609 devel/gperf port. 1610 161120140923: 1612 pjdfstest has been moved from tools/regression/pjdfstest to 1613 contrib/pjdfstest . 1614 161520140922: 1616 At svn r271982, The default linux compat kernel ABI has been adjusted 1617 to 2.6.18 in support of the linux-c6 compat ports infrastructure 1618 update. If you wish to continue using the linux-f10 compat ports, 1619 add compat.linux.osrelease=2.6.16 to your local sysctl.conf. Users are 1620 encouraged to update their linux-compat packages to linux-c6 during 1621 their next update cycle. 1622 162320140729: 1624 The ofwfb driver, used to provide a graphics console on PowerPC when 1625 using vt(4), no longer allows mmap() of all physical memory. This 1626 will prevent Xorg on PowerPC with some ATI graphics cards from 1627 initializing properly unless x11-servers/xorg-server is updated to 1628 1.12.4_8 or newer. 1629 163020140723: 1631 The xdev targets have been converted to using TARGET and 1632 TARGET_ARCH instead of XDEV and XDEV_ARCH. 1633 163420140719: 1635 The default unbound configuration has been modified to address 1636 issues with reverse lookups on networks that use private 1637 address ranges. If you use the local_unbound service, run 1638 "service local_unbound setup" as root to regenerate your 1639 configuration, then "service local_unbound reload" to load the 1640 new configuration. 1641 164220140709: 1643 The GNU texinfo and GNU info pages are not built and installed 1644 anymore, WITH_INFO knob has been added to allow to built and install 1645 them again. 1646 UPDATE: see 20150102 entry on texinfo's removal 1647 164820140708: 1649 The GNU readline library is now an INTERNALLIB - that is, it is 1650 statically linked into consumers (GDB and variants) in the base 1651 system, and the shared library is no longer installed. The 1652 devel/readline port is available for third party software that 1653 requires readline. 1654 165520140702: 1656 The Itanium architecture (ia64) has been removed from the list of 1657 known architectures. This is the first step in the removal of the 1658 architecture. 1659 166020140701: 1661 Commit r268115 has added NFSv4.1 server support, merged from 1662 projects/nfsv4.1-server. Since this includes changes to the 1663 internal interfaces between the NFS related modules, a full 1664 build of the kernel and modules will be necessary. 1665 __FreeBSD_version has been bumped. 1666 166720140629: 1668 The WITHOUT_VT_SUPPORT kernel config knob has been renamed 1669 WITHOUT_VT. (The other _SUPPORT knobs have a consistent meaning 1670 which differs from the behaviour controlled by this knob.) 1671 167220140619: 1673 Maximal length of the serial number in CTL was increased from 16 to 1674 64 chars, that breaks ABI. All CTL-related tools, such as ctladm 1675 and ctld, need to be rebuilt to work with a new kernel. 1676 167720140606: 1678 The libatf-c and libatf-c++ major versions were downgraded to 0 and 1679 1 respectively to match the upstream numbers. They were out of 1680 sync because, when they were originally added to FreeBSD, the 1681 upstream versions were not respected. These libraries are private 1682 and not yet built by default, so renumbering them should be a 1683 non-issue. However, unclean source trees will yield broken test 1684 programs once the operator executes "make delete-old-libs" after a 1685 "make installworld". 1686 1687 Additionally, the atf-sh binary was made private by moving it into 1688 /usr/libexec/. Already-built shell test programs will keep the 1689 path to the old binary so they will break after "make delete-old" 1690 is run. 1691 1692 If you are using WITH_TESTS=yes (not the default), wipe the object 1693 tree and rebuild from scratch to prevent spurious test failures. 1694 This is only needed once: the misnumbered libraries and misplaced 1695 binaries have been added to OptionalObsoleteFiles.inc so they will 1696 be removed during a clean upgrade. 1697 169820140512: 1699 Clang and llvm have been upgraded to 3.4.1 release. 1700 170120140508: 1702 We bogusly installed src.opts.mk in /usr/share/mk. This file should 1703 be removed to avoid issues in the future (and has been added to 1704 ObsoleteFiles.inc). 1705 170620140505: 1707 /etc/src.conf now affects only builds of the FreeBSD src tree. In the 1708 past, it affected all builds that used the bsd.*.mk files. The old 1709 behavior was a bug, but people may have relied upon it. To get this 1710 behavior back, you can .include /etc/src.conf from /etc/make.conf 1711 (which is still global and isn't changed). This also changes the 1712 behavior of incremental builds inside the tree of individual 1713 directories. Set MAKESYSPATH to ".../share/mk" to do that. 1714 Although this has survived make universe and some upgrade scenarios, 1715 other upgrade scenarios may have broken. At least one form of 1716 temporary breakage was fixed with MAKESYSPATH settings for buildworld 1717 as well... In cases where MAKESYSPATH isn't working with this 1718 setting, you'll need to set it to the full path to your tree. 1719 1720 One side effect of all this cleaning up is that bsd.compiler.mk 1721 is no longer implicitly included by bsd.own.mk. If you wish to 1722 use COMPILER_TYPE, you must now explicitly include bsd.compiler.mk 1723 as well. 1724 172520140430: 1726 The lindev device has been removed since /dev/full has been made a 1727 standard device. __FreeBSD_version has been bumped. 1728 172920140424: 1730 The knob WITHOUT_VI was added to the base system, which controls 1731 building ex(1), vi(1), etc. Older releases of FreeBSD required ex(1) 1732 in order to reorder files share/termcap and didn't build ex(1) as a 1733 build tool, so building/installing with WITH_VI is highly advised for 1734 build hosts for older releases. 1735 1736 This issue has been fixed in stable/9 and stable/10 in r277022 and 1737 r276991, respectively. 1738 173920140418: 1740 The YES_HESIOD knob has been removed. It has been obsolete for 1741 a decade. Please move to using WITH_HESIOD instead or your builds 1742 will silently lack HESIOD. 1743 174420140405: 1745 The uart(4) driver has been changed with respect to its handling 1746 of the low-level console. Previously the uart(4) driver prevented 1747 any process from changing the baudrate or the CLOCAL and HUPCL 1748 control flags. By removing the restrictions, operators can make 1749 changes to the serial console port without having to reboot. 1750 However, when getty(8) is started on the serial device that is 1751 associated with the low-level console, a misconfigured terminal 1752 line in /etc/ttys will now have a real impact. 1753 Before upgrading the kernel, make sure that /etc/ttys has the 1754 serial console device configured as 3wire without baudrate to 1755 preserve the previous behaviour. E.g: 1756 ttyu0 "/usr/libexec/getty 3wire" vt100 on secure 1757 175820140306: 1759 Support for libwrap (TCP wrappers) in rpcbind was disabled by default 1760 to improve performance. To re-enable it, if needed, run rpcbind 1761 with command line option -W. 1762 176320140226: 1764 Switched back to the GPL dtc compiler due to updates in the upstream 1765 dts files not being supported by the BSDL dtc compiler. You will need 1766 to rebuild your kernel toolchain to pick up the new compiler. Core dumps 1767 may result while building dtb files during a kernel build if you fail 1768 to do so. Set WITHOUT_GPL_DTC if you require the BSDL compiler. 1769 177020140216: 1771 Clang and llvm have been upgraded to 3.4 release. 1772 177320140216: 1774 The nve(4) driver has been removed. Please use the nfe(4) driver 1775 for NVIDIA nForce MCP Ethernet adapters instead. 1776 177720140212: 1778 An ABI incompatibility crept into the libc++ 3.4 import in r261283. 1779 This could cause certain C++ applications using shared libraries built 1780 against the previous version of libc++ to crash. The incompatibility 1781 has now been fixed, but any C++ applications or shared libraries built 1782 between r261283 and r261801 should be recompiled. 1783 178420140204: 1785 OpenSSH will now ignore errors caused by kernel lacking of Capsicum 1786 capability mode support. Please note that enabling the feature in 1787 kernel is still highly recommended. 1788 178920140131: 1790 OpenSSH is now built with sandbox support, and will use sandbox as 1791 the default privilege separation method. This requires Capsicum 1792 capability mode support in kernel. 1793 179420140128: 1795 The libelf and libdwarf libraries have been updated to newer 1796 versions from upstream. Shared library version numbers for 1797 these two libraries were bumped. Any ports or binaries 1798 requiring these two libraries should be recompiled. 1799 __FreeBSD_version is bumped to 1100006. 1800 180120140110: 1802 If a Makefile in a tests/ directory was auto-generating a Kyuafile 1803 instead of providing an explicit one, this would prevent such 1804 Makefile from providing its own Kyuafile in the future during 1805 NO_CLEAN builds. This has been fixed in the Makefiles but manual 1806 intervention is needed to clean an objdir if you use NO_CLEAN: 1807 # find /usr/obj -name Kyuafile | xargs rm -f 1808 180920131213: 1810 The behavior of gss_pseudo_random() for the krb5 mechanism 1811 has changed, for applications requesting a longer random string 1812 than produced by the underlying enctype's pseudo-random() function. 1813 In particular, the random string produced from a session key of 1814 enctype aes256-cts-hmac-sha1-96 or aes256-cts-hmac-sha1-96 will 1815 be different at the 17th octet and later, after this change. 1816 The counter used in the PRF+ construction is now encoded as a 1817 big-endian integer in accordance with RFC 4402. 1818 __FreeBSD_version is bumped to 1100004. 1819 182020131108: 1821 The WITHOUT_ATF build knob has been removed and its functionality 1822 has been subsumed into the more generic WITHOUT_TESTS. If you were 1823 using the former to disable the build of the ATF libraries, you 1824 should change your settings to use the latter. 1825 182620131025: 1827 The default version of mtree is nmtree which is obtained from 1828 NetBSD. The output is generally the same, but may vary 1829 slightly. If you found you need identical output adding 1830 "-F freebsd9" to the command line should do the trick. For the 1831 time being, the old mtree is available as fmtree. 1832 183320131014: 1834 libbsdyml has been renamed to libyaml and moved to /usr/lib/private. 1835 This will break ports-mgmt/pkg. Rebuild the port, or upgrade to pkg 1836 1.1.4_8 and verify bsdyml not linked in, before running "make 1837 delete-old-libs": 1838 # make -C /usr/ports/ports-mgmt/pkg build deinstall install clean 1839 or 1840 # pkg install pkg; ldd /usr/local/sbin/pkg | grep bsdyml 1841 184220131010: 1843 The stable/10 branch has been created in subversion from head 1844 revision r256279. 1845 1846COMMON ITEMS: 1847 1848 General Notes 1849 ------------- 1850 Avoid using make -j when upgrading. While generally safe, there are 1851 sometimes problems using -j to upgrade. If your upgrade fails with 1852 -j, please try again without -j. From time to time in the past there 1853 have been problems using -j with buildworld and/or installworld. This 1854 is especially true when upgrading between "distant" versions (eg one 1855 that cross a major release boundary or several minor releases, or when 1856 several months have passed on the -current branch). 1857 1858 Sometimes, obscure build problems are the result of environment 1859 poisoning. This can happen because the make utility reads its 1860 environment when searching for values for global variables. To run 1861 your build attempts in an "environmental clean room", prefix all make 1862 commands with 'env -i '. See the env(1) manual page for more details. 1863 1864 When upgrading from one major version to another it is generally best to 1865 upgrade to the latest code in the currently installed branch first, then 1866 do an upgrade to the new branch. This is the best-tested upgrade path, 1867 and has the highest probability of being successful. Please try this 1868 approach if you encounter problems with a major version upgrade. Since 1869 the stable 4.x branch point, one has generally been able to upgrade from 1870 anywhere in the most recent stable branch to head / current (or even the 1871 last couple of stable branches). See the top of this file when there's 1872 an exception. 1873 1874 When upgrading a live system, having a root shell around before 1875 installing anything can help undo problems. Not having a root shell 1876 around can lead to problems if pam has changed too much from your 1877 starting point to allow continued authentication after the upgrade. 1878 1879 This file should be read as a log of events. When a later event changes 1880 information of a prior event, the prior event should not be deleted. 1881 Instead, a pointer to the entry with the new information should be 1882 placed in the old entry. Readers of this file should also sanity check 1883 older entries before relying on them blindly. Authors of new entries 1884 should write them with this in mind. 1885 1886 ZFS notes 1887 --------- 1888 When upgrading the boot ZFS pool to a new version, always follow 1889 these two steps: 1890 1891 1.) recompile and reinstall the ZFS boot loader and boot block 1892 (this is part of "make buildworld" and "make installworld") 1893 1894 2.) update the ZFS boot block on your boot drive 1895 1896 The following example updates the ZFS boot block on the first 1897 partition (freebsd-boot) of a GPT partitioned drive ada0: 1898 "gpart bootcode -p /boot/gptzfsboot -i 1 ada0" 1899 1900 Non-boot pools do not need these updates. 1901 1902 To build a kernel 1903 ----------------- 1904 If you are updating from a prior version of FreeBSD (even one just 1905 a few days old), you should follow this procedure. It is the most 1906 failsafe as it uses a /usr/obj tree with a fresh mini-buildworld, 1907 1908 make kernel-toolchain 1909 make -DALWAYS_CHECK_MAKE buildkernel KERNCONF=YOUR_KERNEL_HERE 1910 make -DALWAYS_CHECK_MAKE installkernel KERNCONF=YOUR_KERNEL_HERE 1911 1912 To test a kernel once 1913 --------------------- 1914 If you just want to boot a kernel once (because you are not sure 1915 if it works, or if you want to boot a known bad kernel to provide 1916 debugging information) run 1917 make installkernel KERNCONF=YOUR_KERNEL_HERE KODIR=/boot/testkernel 1918 nextboot -k testkernel 1919 1920 To rebuild everything and install it on the current system. 1921 ----------------------------------------------------------- 1922 # Note: sometimes if you are running current you gotta do more than 1923 # is listed here if you are upgrading from a really old current. 1924 1925 <make sure you have good level 0 dumps> 1926 make buildworld 1927 make buildkernel KERNCONF=YOUR_KERNEL_HERE 1928 make installkernel KERNCONF=YOUR_KERNEL_HERE 1929 [1] 1930 <reboot in single user> [3] 1931 mergemaster -Fp [5] 1932 make installworld 1933 mergemaster -Fi [4] 1934 make delete-old [6] 1935 <reboot> 1936 1937 To cross-install current onto a separate partition 1938 -------------------------------------------------- 1939 # In this approach we use a separate partition to hold 1940 # current's root, 'usr', and 'var' directories. A partition 1941 # holding "/", "/usr" and "/var" should be about 2GB in 1942 # size. 1943 1944 <make sure you have good level 0 dumps> 1945 <boot into -stable> 1946 make buildworld 1947 make buildkernel KERNCONF=YOUR_KERNEL_HERE 1948 <maybe newfs current's root partition> 1949 <mount current's root partition on directory ${CURRENT_ROOT}> 1950 make installworld DESTDIR=${CURRENT_ROOT} -DDB_FROM_SRC 1951 make distribution DESTDIR=${CURRENT_ROOT} # if newfs'd 1952 make installkernel KERNCONF=YOUR_KERNEL_HERE DESTDIR=${CURRENT_ROOT} 1953 cp /etc/fstab ${CURRENT_ROOT}/etc/fstab # if newfs'd 1954 <edit ${CURRENT_ROOT}/etc/fstab to mount "/" from the correct partition> 1955 <reboot into current> 1956 <do a "native" rebuild/install as described in the previous section> 1957 <maybe install compatibility libraries from ports/misc/compat*> 1958 <reboot> 1959 1960 1961 To upgrade in-place from stable to current 1962 ---------------------------------------------- 1963 <make sure you have good level 0 dumps> 1964 make buildworld [9] 1965 make buildkernel KERNCONF=YOUR_KERNEL_HERE [8] 1966 make installkernel KERNCONF=YOUR_KERNEL_HERE 1967 [1] 1968 <reboot in single user> [3] 1969 mergemaster -Fp [5] 1970 make installworld 1971 mergemaster -Fi [4] 1972 make delete-old [6] 1973 <reboot> 1974 1975 Make sure that you've read the UPDATING file to understand the 1976 tweaks to various things you need. At this point in the life 1977 cycle of current, things change often and you are on your own 1978 to cope. The defaults can also change, so please read ALL of 1979 the UPDATING entries. 1980 1981 Also, if you are tracking -current, you must be subscribed to 1982 freebsd-current@freebsd.org. Make sure that before you update 1983 your sources that you have read and understood all the recent 1984 messages there. If in doubt, please track -stable which has 1985 much fewer pitfalls. 1986 1987 [1] If you have third party modules, such as vmware, you 1988 should disable them at this point so they don't crash your 1989 system on reboot. 1990 1991 [3] From the bootblocks, boot -s, and then do 1992 fsck -p 1993 mount -u / 1994 mount -a 1995 sh /etc/rc.d/zfs start # mount zfs filesystem, if needed 1996 cd src # full path to source 1997 adjkerntz -i # if CMOS is wall time 1998 Also, when doing a major release upgrade, it is required that 1999 you boot into single user mode to do the installworld. 2000 2001 [4] Note: This step is non-optional. Failure to do this step 2002 can result in a significant reduction in the functionality of the 2003 system. Attempting to do it by hand is not recommended and those 2004 that pursue this avenue should read this file carefully, as well 2005 as the archives of freebsd-current and freebsd-hackers mailing lists 2006 for potential gotchas. The -U option is also useful to consider. 2007 See mergemaster(8) for more information. 2008 2009 [5] Usually this step is a no-op. However, from time to time 2010 you may need to do this if you get unknown user in the following 2011 step. It never hurts to do it all the time. You may need to 2012 install a new mergemaster (cd src/usr.sbin/mergemaster && make 2013 install) after the buildworld before this step if you last updated 2014 from current before 20130425 or from -stable before 20130430. 2015 2016 [6] This only deletes old files and directories. Old libraries 2017 can be deleted by "make delete-old-libs", but you have to make 2018 sure that no program is using those libraries anymore. 2019 2020 [8] The new kernel must be able to run existing binaries used by an 2021 installworld. When upgrading across major versions, the new kernel's 2022 configuration must include the correct COMPAT_FREEBSD<n> option for 2023 existing binaries (e.g. COMPAT_FREEBSD11 to run 11.x binaries). Failure 2024 to do so may leave you with a system that is hard to boot to recover. A 2025 GENERIC kernel will include suitable compatibility options to run 2026 binaries from older branches. Note that the ability to run binaries 2027 from unsupported branches is not guaranteed. 2028 2029 Make sure that you merge any new devices from GENERIC since the 2030 last time you updated your kernel config file. Options also 2031 change over time, so you may need to adjust your custom kernels 2032 for these as well. 2033 2034 [9] If CPUTYPE is defined in your /etc/make.conf, make sure to use the 2035 "?=" instead of the "=" assignment operator, so that buildworld can 2036 override the CPUTYPE if it needs to. 2037 2038 MAKEOBJDIRPREFIX must be defined in an environment variable, and 2039 not on the command line, or in /etc/make.conf. buildworld will 2040 warn if it is improperly defined. 2041FORMAT: 2042 2043This file contains a list, in reverse chronological order, of major 2044breakages in tracking -current. It is not guaranteed to be a complete 2045list of such breakages, and only contains entries since September 23, 2011. 2046If you need to see UPDATING entries from before that date, you will need 2047to fetch an UPDATING file from an older FreeBSD release. 2048 2049Copyright information: 2050 2051Copyright 1998-2009 M.
