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 3420190507: 35 The IPSEC option has been removed from GENERIC. Users requiring 36 ipsec(4) must now load the ipsec(4) kernel module. 37 3820190507: 39 The tap(4) driver has been folded into tun(4), and the module has been 40 renamed to tuntap. You should update any kld_load="if_tap" or 41 kld_load="if_tun" entries in /etc/rc.conf, if_tap_load="YES" or 42 if_tun_load="YES" entries in /boot/loader.conf to load the if_tuntap 43 module instead, and "device tap" or "device tun" entries in kernel 44 config files to select the tuntap device instead. 45 4620190418: 47 The following knobs have been added related to tradeoffs between 48 safe use of the random device and availability in the absence of 49 entropy: 50 51 kern.random.initial_seeding.bypass_before_seeding: tunable; set 52 non-zero to bypass the random device prior to seeding, or zero to 53 block random requests until the random device is initially seeded. 54 For now, set to 1 (unsafe) by default to restore pre-r346250 boot 55 availability properties. 56 57 kern.random.initial_seeding.read_random_bypassed_before_seeding: 58 read-only diagnostic sysctl that is set when bypass is enabled and 59 read_random(9) is bypassed, to enable programmatic handling of this 60 initial condition, if desired. 61 62 kern.random.initial_seeding.arc4random_bypassed_before_seeding: 63 Similar to the above, but for for arc4random(9) initial seeding. 64 65 kern.random.initial_seeding.disable_bypass_warnings: tunable; set 66 non-zero to disable warnings in dmesg when the same conditions are 67 met as for the diagnostic sysctls above. Defaults to zero, i.e., 68 produce warnings in dmesg when the conditions are met. 69 7020190416: 71 The tunable "security.stack_protect.permit_nonrandom_cookies" may be 72 set to a non-zero value to boot systems that do not provide early 73 entropy. Otherwise, such systems may see the panic message: 74 "cannot initialize stack cookies because random device is not yet 75 seeded." 76 7720190416: 78 The loadable random module KPI has changed; the random_infra_init() 79 routine now requires a 3rd function pointer for a bool (*)(void) 80 method that returns true if the random device is seeded (and 81 therefore unblocked). 82 8320190404: 84 r345895 reverts r320698. This implies that an nfsuserd(8) daemon 85 built from head sources between r320757 (July 6, 2017) and 86 r338192 (Aug. 22, 2018) will not work unless the "-use-udpsock" 87 is added to the command line. 88 nfsuserd daemons built from head sources that are post-r338192 are 89 not affected and should continue to work. 90 9120190320: 92 The fuse(4) module has been renamed to fusefs(4) for consistency with 93 other filesystems. You should update any kld_load="fuse" entries in 94 /etc/rc.conf, fuse_load="YES" entries in /boot/loader.conf, and 95 "options FUSE" entries in kernel config files. 96 9720190304: 98 Clang, llvm, lld, lldb, compiler-rt and libc++ have been upgraded to 99 8.0.0. Please see the 20141231 entry below for information about 100 prerequisites and upgrading, if you are not already using clang 3.5.0 101 or higher. 102 10320190226: 104 geom_uzip(4) depends on the new module xz. If geom_uzip is statically 105 compiled into your custom kernel, add 'device xz' statement to the 106 kernel config. 107 10820190219: 109 drm and drm2 have been removed from the tree. Please see 110 https://wiki.freebsd.org/Graphics for the latest information on 111 migrating to the drm ports. 112 11320190131: 114 Iflib is no longer unconditionally compiled into the kernel. Drivers 115 using iflib and statically compiled into the kernel, now require 116 the 'device iflib' config option. For the same drivers loaded as 117 modules on kernels not having 'device iflib', the iflib.ko module 118 is loaded automatically. 119 12020190125: 121 The IEEE80211_AMPDU_AGE and AH_SUPPORT_AR5416 kernel configuration 122 options no longer exist since r343219 and r343427 respectively; 123 nothing uses them, so they should be just removed from custom 124 kernel config files. 125 12620181230: 127 r342635 changes the way efibootmgr(8) works by requiring users to add 128 the -b (bootnum) parameter for commands where the bootnum was previously 129 specified with each option. For example 'efibootmgr -B 0001' is now 130 'efibootmgr -B -b 0001'. 131 13220181220: 133 r342286 modifies the NFSv4 server so that it obeys vfs.nfsd.nfs_privport 134 in the same as it is applied to NFSv2 and 3. This implies that NFSv4 135 servers that have vfs.nfsd.nfs_privport set will only allow mounts 136 from clients using a reserved port#. Since both the FreeBSD and Linux 137 NFSv4 clients use reserved port#s by default, this should not affect 138 most NFSv4 mounts. 139 14020181219: 141 The XLP config has been removed. We can't support 64-bit atomics in this 142 kernel because it is running in 32-bit mode. XLP users must transition 143 to running a 64-bit kernel (XLP64 or XLPN32). 144 145 The mips GXEMUL support has been removed from FreeBSD. MALTA* + qemu is 146 the preferred emulator today and we don't need two different ones. 147 148 The old sibyte / swarm / Broadcom BCM1250 support has been 149 removed from the mips port. 150 15120181211: 152 Clang, llvm, lld, lldb, compiler-rt and libc++ have been upgraded to 153 7.0.1. Please see the 20141231 entry below for information about 154 prerequisites and upgrading, if you are not already using clang 3.5.0 155 or higher. 156 15720181211: 158 Remove the timed and netdate programs from the base tree. Setting 159 the time with these daemons has been obsolete for over a decade. 160 16120181126: 162 On amd64, arm64 and armv7 (architectures that install LLVM's ld.lld 163 linker as /usr/bin/ld) GNU ld is no longer installed as ld.bfd, as 164 it produces broken binaries when ifuncs are in use. Users needing 165 GNU ld should install the binutils port or package. 166 16720181123: 168 The BSD crtbegin and crtend code has been enabled by default. It has 169 had extensive testing on amd64, arm64, and i386. It can be disabled 170 by building a world with -DWITHOUT_BSD_CRTBEGIN. 171 17220181115: 173 The set of CTM commands (ctm, ctm_smail, ctm_rmail, ctm_dequeue) 174 has been converted to a port (misc/ctm) and will be removed from 175 FreeBSD-13. It is available as a package (ctm) for all supported 176 FreeBSD versions. 177 17820181110: 179 The default newsyslog.conf(5) file has been changed to only include 180 files in /etc/newsyslog.conf.d/ and /usr/local/etc/newsyslog.conf.d/ if 181 the filenames end in '.conf' and do not begin with a '.'. 182 183 You should check the configuration files in these two directories match 184 this naming convention. You can verify which configuration files are 185 being included using the command: 186 $ newsyslog -Nrv 187 18820181015: 189 Ports for the DRM modules have been simplified. Now, amd64 users should 190 just install the drm-kmod port. All others should install 191 drm-legacy-kmod. 192 193 Graphics hardware that's newer than about 2010 usually works with 194 drm-kmod. For hardware older than 2013, however, some users will need 195 to use drm-legacy-kmod if drm-kmod doesn't work for them. Hardware older 196 than 2008 usually only works in drm-legacy-kmod. The graphics team can 197 only commit to hardware made since 2013 due to the complexity of the 198 market and difficulty to test all the older cards effectively. If you 199 have hardware supported by drm-kmod, you are strongly encouraged to use 200 that as you will get better support. 201 202 Other than KPI chasing, drm-legacy-kmod will not be updated. As outlined 203 elsewhere, the drm and drm2 modules will be eliminated from the src base 204 soon (with a limited exception for arm). Please update to the package 205 asap and report any issues to x11@freebsd.org. 206 207 Generally, anybody using the drm*-kmod packages should add 208 WITHOUT_DRM_MODULE=t and WITHOUT_DRM2_MODULE=t to avoid nasty 209 cross-threading surprises, especially with automatic driver 210 loading from X11 startup. These will become the defaults in 13-current 211 shortly. 212 21320181012: 214 The ixlv(4) driver has been renamed to iavf(4). As a consequence, 215 custom kernel and module loading configuration files must be updated 216 accordingly. Moreover, interfaces previous presented as ixlvN to the 217 system are now exposed as iavfN and network configuration files must 218 be adjusted as necessary. 219 22020181009: 221 OpenSSL has been updated to version 1.1.1. This update included 222 additional various API changes throughout the base system. It is 223 important to rebuild third-party software after upgrading. The value 224 of __FreeBSD_version has been bumped accordingly. 225 22620181006: 227 The legacy DRM modules and drivers have now been added to the loader's 228 module blacklist, in favor of loading them with kld_list in rc.conf(5). 229 The module blacklist may be overridden with the loader.conf(5) 230 'module_blacklist' variable, but loading them via rc.conf(5) is strongly 231 encouraged. 232 23320181002: 234 The cam(4) based nda(4) driver will be used over nvd(4) by default on 235 powerpc64. You may set 'options NVME_USE_NVD=1' in your kernel conf or 236 loader tunable 'hw.nvme.use_nvd=1' if you wish to use the existing 237 driver. Make sure to edit /boot/etc/kboot.conf and fstab to use the 238 nda device name. 239 24020180913: 241 Reproducible build mode is now on by default, in preparation for 242 FreeBSD 12.0. This eliminates build metadata such as the user, 243 host, and time from the kernel (and uname), unless the working tree 244 corresponds to a modified checkout from a version control system. 245 The previous behavior can be obtained by setting the /etc/src.conf 246 knob WITHOUT_REPRODUCIBLE_BUILD. 247 24820180826: 249 The Yarrow CSPRNG has been removed from the kernel as it has not been 250 supported by its designers since at least 2003. Fortuna has been the 251 default since FreeBSD-11. 252 25320180822: 254 devctl freeze/thaw have gone into the tree, the rc scripts have been 255 updated to use them and devmatch has been changed. You should update 256 kernel, userland and rc scripts all at the same time. 257 25820180818: 259 The default interpreter has been switched from 4th to Lua. 260 LOADER_DEFAULT_INTERP, documented in build(7), will override the default 261 interpreter. If you have custom FORTH code you will need to set 262 LOADER_DEFAULT_INTERP=4th (valid values are 4th, lua or simp) in 263 src.conf for the build. This will create default hard links between 264 loader and loader_4th instead of loader and loader_lua, the new default. 265 If you are using UEFI it will create the proper hard link to loader.efi. 266 267 bhyve uses userboot.so. It remains 4th-only until some issues are solved 268 regarding coexisting with multiple versions of FreeBSD are resolved. 269 27020180815: 271 ls(1) now respects the COLORTERM environment variable used in other 272 systems and software to indicate that a colored terminal is both 273 supported and desired. If ls(1) is suddenly emitting colors, they may 274 be disabled again by either removing the unwanted COLORTERM from your 275 environment, or using `ls --color=never`. The ls(1) specific CLICOLOR 276 may not be observed in a future release. 277 27820180808: 279 The default pager for most commands has been changed to "less". To 280 restore the old behavior, set PAGER="more" and MANPAGER="more -s" in 281 your environment. 282 28320180731: 284 The jedec_ts(4) driver has been removed. A superset of its functionality 285 is available in the jedec_dimm(4) driver, and the manpage for that 286 driver includes migration instructions. If you have "device jedec_ts" 287 in your kernel configuration file, it must be removed. 288 28920180730: 290 amd64/GENERIC now has EFI runtime services, EFIRT, enabled by default. 291 This should have no effect if the kernel is booted via BIOS/legacy boot. 292 EFIRT may be disabled via a loader tunable, efi.rt.disabled, if a system 293 has a buggy firmware that prevents a successful boot due to use of 294 runtime services. 295 29620180727: 297 Atmel AT91RM9200 and AT91SAM9, Cavium CNS 11xx and XScale 298 support has been removed from the tree. These ports were 299 obsolete and/or known to be broken for many years. 300 30120180723: 302 loader.efi has been augmented to participate more fully in the 303 UEFI boot manager protocol. loader.efi will now look at the 304 BootXXXX environment variable to determine if a specific kernel 305 or root partition was specified. XXXX is derived from BootCurrent. 306 efibootmgr(8) manages these standard UEFI variables. 307 30820180720: 309 zfsloader's functionality has now been folded into loader. 310 zfsloader is no longer necessary once you've updated your 311 boot blocks. For a transition period, we will install a 312 hardlink for zfsloader to loader to allow a smooth transition 313 until the boot blocks can be updated (hard link because old 314 zfs boot blocks don't understand symlinks). 315 31620180719: 317 ARM64 now have efifb support, if you want to have serial console 318 on your arm64 board when an screen is connected and the bootloader 319 setup a frame buffer for us to use, just add : 320 boot_serial=YES 321 boot_multicons=YES 322 in /boot/loader.conf 323 For Raspberry Pi 3 (RPI) users, this is needed even if you don't have 324 an screen connected as the firmware will setup a frame buffer are that 325 u-boot will expose as an EFI frame buffer. 326 32720180719: 328 New uid:gid added, ntpd:ntpd (123:123). Be sure to run mergemaster 329 or take steps to update /etc/passwd before doing installworld on 330 existing systems. Do not skip the "mergemaster -Fp" step before 331 installworld, as described in the update procedures near the bottom 332 of this document. Also, rc.d/ntpd now starts ntpd(8) as user ntpd 333 if the new mac_ntpd(4) policy is available, unless ntpd_flags or 334 the ntp config file contain options that change file/dir locations. 335 When such options (e.g., "statsdir" or "crypto") are used, ntpd can 336 still be run as non-root by setting ntpd_user=ntpd in rc.conf, after 337 taking steps to ensure that all required files/dirs are accessible 338 by the ntpd user. 339 34020180717: 341 Big endian arm support has been removed. 342 34320180711: 344 The static environment setup in kernel configs is no longer mutually 345 exclusive with the loader(8) environment by default. In order to 346 restore the previous default behavior of disabling the loader(8) 347 environment if a static environment is present, you must specify 348 loader_env.disabled=1 in the static environment. 349 35020180705: 351 The ABI of syscalls used by management tools like sockstat and 352 netstat has been broken to allow 32-bit binaries to work on 353 64-bit kernels without modification. These programs will need 354 to match the kernel in order to function. External programs may 355 require minor modifications to accommodate a change of type in 356 structures from pointers to 64-bit virtual addresses. 357 35820180702: 359 On i386 and amd64 atomics are now inlined. Out of tree modules using 360 atomics will need to be rebuilt. 361 36220180701: 363 The '%I' format in the kern.corefile sysctl limits the number of 364 core files that a process can generate to the number stored in the 365 debug.ncores sysctl. The '%I' format is replaced by the single digit 366 index. Previously, if all indexes were taken the kernel would overwrite 367 only a core file with the highest index in a filename. 368 Currently the system will create a new core file if there is a free 369 index or if all slots are taken it will overwrite the oldest one. 370 37120180630: 372 Clang, llvm, lld, lldb, compiler-rt and libc++ have been upgraded to 373 6.0.1. Please see the 20141231 entry below for information about 374 prerequisites and upgrading, if you are not already using clang 3.5.0 375 or higher. 376 37720180628: 378 r335753 introduced a new quoting method. However, etc/devd/devmatch.conf 379 needed to be changed to work with it. This change was made with r335763 380 and requires a mergemaster / etcupdate / etc to update the installed 381 file. 382 38320180612: 384 r334930 changed the interface between the NFS modules, so they all 385 need to be rebuilt. r335018 did a __FreeBSD_version bump for this. 386 38720180530: 388 As of r334391 lld is the default amd64 system linker; it is installed 389 as /usr/bin/ld. Kernel build workarounds (see 20180510 entry) are no 390 longer necessary. 391 39220180530: 393 The kernel / userland interface for devinfo changed, so you'll 394 need a new kernel and userland as a pair for it to work (rebuilding 395 lib/libdevinfo is all that's required). devinfo and devmatch will 396 not work, but everything else will when there's a mismatch. 397 39820180523: 399 The on-disk format for hwpmc callchain records has changed to include 400 threadid corresponding to a given record. This changes the field offsets 401 and thus requires that libpmcstat be rebuilt before using a kernel 402 later than r334108. 403 40420180517: 405 The vxge(4) driver has been removed. This driver was introduced into 406 HEAD one week before the Exar left the Ethernet market and is not 407 known to be used. If you have device vxge in your kernel config file 408 it must be removed. 409 41020180510: 411 The amd64 kernel now requires a ld that supports ifunc to produce a 412 working kernel, either lld or a newer binutils. lld is built by default 413 on amd64, and the 'buildkernel' target uses it automatically. However, 414 it is not the default linker, so building the kernel the traditional 415 way requires LD=ld.lld on the command line (or LD=/usr/local/bin/ld for 416 binutils port/package). lld will soon be default, and this requirement 417 will go away. 418 419 NOTE: As of r334391 lld is the default system linker on amd64, and no 420 workaround is necessary. 421 42220180508: 423 The nxge(4) driver has been removed. This driver was for PCI-X 10g 424 cards made by s2io/Neterion. The company was acquired by Exar and 425 no longer sells or supports Ethernet products. If you have device 426 nxge in your kernel config file it must be removed. 427 42820180504: 429 The tz database (tzdb) has been updated to 2018e. This version more 430 correctly models time stamps in time zones with negative DST such as 431 Europe/Dublin (from 1971 on), Europe/Prague (1946/7), and 432 Africa/Windhoek (1994/2017). This does not affect the UT offsets, only 433 time zone abbreviations and the tm_isdst flag. 434 43520180502: 436 The ixgb(4) driver has been removed. This driver was for an early and 437 uncommon legacy PCI 10GbE for a single ASIC, Intel 82597EX. Intel 438 quickly shifted to the long lived ixgbe family. If you have device 439 ixgb in your kernel config file it must be removed. 440 44120180501: 442 The lmc(4) driver has been removed. This was a WAN interface 443 card that was already reportedly rare in 2003, and had an ambiguous 444 license. If you have device lmc in your kernel config file it must 445 be removed. 446 44720180413: 448 Support for Arcnet networks has been removed. If you have device 449 arcnet or device cm in your kernel config file they must be 450 removed. 451 45220180411: 453 Support for FDDI networks has been removed. If you have device 454 fddi or device fpa in your kernel config file they must be 455 removed. 456 45720180406: 458 In addition to supporting RFC 3164 formatted messages, the 459 syslogd(8) service is now capable of parsing RFC 5424 formatted 460 log messages. The main benefit of using RFC 5424 is that clients 461 may now send log messages with timestamps containing year numbers, 462 microseconds and time zone offsets. 463 464 Similarly, the syslog(3) C library function has been altered to 465 send RFC 5424 formatted messages to the local system logging 466 daemon. On systems using syslogd(8), this change should have no 467 negative impact, as long as syslogd(8) and the C library are 468 updated at the same time. On systems using a different system 469 logging daemon, it may be necessary to make configuration 470 adjustments, depending on the software used. 471 472 When using syslog-ng, add the 'syslog-protocol' flag to local 473 input sources to enable parsing of RFC 5424 formatted messages: 474 475 source src { 476 unix-dgram("/var/run/log" flags(syslog-protocol)); 477 } 478 479 When using rsyslog, disable the 'SysSock.UseSpecialParser' option 480 of the 'imuxsock' module to let messages be processed by the 481 regular RFC 3164/5424 parsing pipeline: 482 483 module(load="imuxsock" SysSock.UseSpecialParser="off") 484 485 Do note that these changes only affect communication between local 486 applications and syslogd(8). The format that syslogd(8) uses to 487 store messages on disk or forward messages to other systems 488 remains unchanged. syslogd(8) still uses RFC 3164 for these 489 purposes. Options to customize this behaviour will be added in the 490 future. Utilities that process log files stored in /var/log are 491 thus expected to continue to function as before. 492 493 __FreeBSD_version has been incremented to 1200061 to denote this 494 change. 495 49620180328: 497 Support for token ring networks has been removed. If you 498 have "device token" in your kernel config you should remove 499 it. No device drivers supported token ring. 500 50120180323: 502 makefs was modified to be able to tag ISO9660 El Torito boot catalog 503 entries as EFI instead of overloading the i386 tag as done previously. 504 The amd64 mkisoimages.sh script used to build amd64 ISO images for 505 release was updated to use this. This may mean that makefs must be 506 updated before "make cdrom" can be run in the release directory. This 507 should be as simple as: 508 509 $ cd $SRCDIR/usr.sbin/makefs 510 $ make depend all install 511 51220180212: 513 FreeBSD boot loader enhanced with Lua scripting. It's purely opt-in for 514 now by building WITH_LOADER_LUA and WITHOUT_FORTH in /etc/src.conf. 515 Co-existence for the transition period will come shortly. Booting is a 516 complex environment and test coverage for Lua-enabled loaders has been 517 thin, so it would be prudent to assume it might not work and make 518 provisions for backup boot methods. 519 52020180211: 521 devmatch functionality has been turned on in devd. It will automatically 522 load drivers for unattached devices. This may cause unexpected drivers 523 to be loaded. Please report any problems to current@ and 524 imp@freebsd.org. 525 52620180114: 527 Clang, llvm, lld, lldb, compiler-rt and libc++ have been upgraded to 528 6.0.0. Please see the 20141231 entry below for information about 529 prerequisites and upgrading, if you are not already using clang 3.5.0 530 or higher. 531 53220180110: 533 LLVM's lld linker is now used as the FreeBSD/amd64 bootstrap linker. 534 This means it is used to link the kernel and userland libraries and 535 executables, but is not yet installed as /usr/bin/ld by default. 536 537 To revert to ld.bfd as the bootstrap linker, in /etc/src.conf set 538 WITHOUT_LLD_BOOTSTRAP=yes 539 54020180110: 541 On i386, pmtimer has been removed. Its functionality has been folded 542 into apm. It was a no-op on ACPI in current for a while now (but was 543 still needed on i386 in FreeBSD 11 and earlier). Users may need to 544 remove it from kernel config files. 545 54620180104: 547 The use of RSS hash from the network card aka flowid has been 548 disabled by default for lagg(4) as it's currently incompatible with 549 the lacp and loadbalance protocols. 550 551 This can be re-enabled by setting the following in loader.conf: 552 net.link.lagg.default_use_flowid="1" 553 55420180102: 555 The SW_WATCHDOG option is no longer necessary to enable the 556 hardclock-based software watchdog if no hardware watchdog is 557 configured. As before, SW_WATCHDOG will cause the software 558 watchdog to be enabled even if a hardware watchdog is configured. 559 56020171215: 561 r326887 fixes the issue described in the 20171214 UPDATING entry. 562 r326888 flips the switch back to building GELI support always. 563 56420171214: 565 r362593 broke ZFS + GELI support for reasons unknown. However, 566 it also broke ZFS support generally, so GELI has been turned off 567 by default as the lesser evil in r326857. If you boot off ZFS and/or 568 GELI, it might not be a good time to update. 569 57020171125: 571 PowerPC users must update loader(8) by rebuilding world before 572 installing a new kernel, as the protocol connecting them has 573 changed. Without the update, loader metadata will not be passed 574 successfully to the kernel and users will have to enter their 575 root partition at the kernel mountroot prompt to continue booting. 576 Newer versions of loader can boot old kernels without issue. 577 57820171110: 579 The LOADER_FIREWIRE_SUPPORT build variable as been renamed to 580 WITH/OUT_LOADER_FIREWIRE. LOADER_{NO_,}GELI_SUPPORT has been renamed 581 to WITH/OUT_LOADER_GELI. 582 58320171106: 584 The naive and non-compliant support of posix_fallocate(2) in ZFS 585 has been removed as of r325320. The system call now returns EINVAL 586 when used on a ZFS file. Although the new behavior complies with the 587 standard, some consumers are not prepared to cope with it. 588 One known victim is lld prior to r325420. 589 59020171102: 591 Building in a FreeBSD src checkout will automatically create object 592 directories now rather than store files in the current directory if 593 'make obj' was not ran. Calling 'make obj' is no longer necessary. 594 This feature can be disabled by setting WITHOUT_AUTO_OBJ=yes in 595 /etc/src-env.conf (not /etc/src.conf), or passing the option in the 596 environment. 597 59820171101: 599 The default MAKEOBJDIR has changed from /usr/obj/<srcdir> for native 600 builds, and /usr/obj/<arch>/<srcdir> for cross-builds, to a unified 601 /usr/obj/<srcdir>/<arch>. This behavior can be changed to the old 602 format by setting WITHOUT_UNIFIED_OBJDIR=yes in /etc/src-env.conf, 603 the environment, or with -DWITHOUT_UNIFIED_OBJDIR when building. 604 The UNIFIED_OBJDIR option is a transitional feature that will be 605 removed for 12.0 release; please migrate to the new format for any 606 tools by looking up the OBJDIR used by 'make -V .OBJDIR' means rather 607 than hardcoding paths. 608 60920171028: 610 The native-xtools target no longer installs the files by default to the 611 OBJDIR. Use the native-xtools-install target with a DESTDIR to install 612 to ${DESTDIR}/${NXTP} where NXTP defaults to /nxb-bin. 613 61420171021: 615 As part of the boot loader infrastructure cleanup, LOADER_*_SUPPORT 616 options are changing from controlling the build if defined / undefined 617 to controlling the build with explicit 'yes' or 'no' values. They will 618 shift to WITH/WITHOUT options to match other options in the system. 619 62020171010: 621 libstand has turned into a private library for sys/boot use only. 622 It is no longer supported as a public interface outside of sys/boot. 623 62420171005: 625 The arm port has split armv6 into armv6 and armv7. armv7 is now 626 a valid TARGET_ARCH/MACHINE_ARCH setting. If you have an armv7 system 627 and are running a kernel from before r324363, you will need to add 628 MACHINE_ARCH=armv7 to 'make buildworld' to do a native build. 629 63020171003: 631 When building multiple kernels using KERNCONF, non-existent KERNCONF 632 files will produce an error and buildkernel will fail. Previously 633 missing KERNCONF files silently failed giving no indication as to 634 why, only to subsequently discover during installkernel that the 635 desired kernel was never built in the first place. 636 63720170912: 638 The default serial number format for CTL LUNs has changed. This will 639 affect users who use /dev/diskid/* device nodes, or whose FibreChannel 640 or iSCSI clients care about their LUNs' serial numbers. Users who 641 require serial number stability should hardcode serial numbers in 642 /etc/ctl.conf . 643 64420170912: 645 For 32-bit arm compiled for hard-float support, soft-floating point 646 binaries now always get their shared libraries from 647 LD_SOFT_LIBRARY_PATH (in the past, this was only used if 648 /usr/libsoft also existed). Only users with a hard-float ld.so, but 649 soft-float everything else should be affected. 650 65120170826: 652 The geli password typed at boot is now hidden. To restore the previous 653 behavior, see geli(8) for configuration options. 654 65520170825: 656 Move PMTUD blackhole counters to TCPSTATS and remove them from bare 657 sysctl values. Minor nit, but requires a rebuild of both world/kernel 658 to complete. 659 66020170814: 661 "make check" behavior (made in ^/head@r295380) has been changed to 662 execute from a limited sandbox, as opposed to executing from 663 ${TESTSDIR}. 664 665 Behavioral changes: 666 - The "beforecheck" and "aftercheck" targets are now specified. 667 - ${CHECKDIR} (added in commit noted above) has been removed. 668 - Legacy behavior can be enabled by setting 669 WITHOUT_MAKE_CHECK_USE_SANDBOX in src.conf(5) or the environment. 670 671 If the limited sandbox mode is enabled, "make check" will execute 672 "make distribution", then install, execute the tests, and clean up the 673 sandbox if successful. 674 675 The "make distribution" and "make install" targets are typically run as 676 root to set appropriate permissions and ownership at installation time. 677 The end-user should set "WITH_INSTALL_AS_USER" in src.conf(5) or the 678 environment if executing "make check" with limited sandbox mode using 679 an unprivileged user. 680 68120170808: 682 Since the switch to GPT disk labels, fsck for UFS/FFS has been 683 unable to automatically find alternate superblocks. As of r322297, 684 the information needed to find alternate superblocks has been 685 moved to the end of the area reserved for the boot block. 686 Filesystems created with a newfs of this vintage or later 687 will create the recovery information. If you have a filesystem 688 created prior to this change and wish to have a recovery block 689 created for your filesystem, you can do so by running fsck in 690 foreground mode (i.e., do not use the -p or -y options). As it 691 starts, fsck will ask ``SAVE DATA TO FIND ALTERNATE SUPERBLOCKS'' 692 to which you should answer yes. 693 69420170728: 695 As of r321665, an NFSv4 server configuration that services 696 Kerberos mounts or clients that do not support the uid/gid in 697 owner/owner_group string capability, must explicitly enable 698 the nfsuserd daemon by adding nfsuserd_enable="YES" to the 699 machine's /etc/rc.conf file. 700 70120170722: 702 Clang, llvm, lldb, compiler-rt and libc++ have been upgraded to 5.0.0. 703 Please see the 20141231 entry below for information about prerequisites 704 and upgrading, if you are not already using clang 3.5.0 or higher. 705 70620170701: 707 WITHOUT_RCMDS is now the default. Set WITH_RCMDS if you need the 708 r-commands (rlogin, rsh, etc.) to be built with the base system. 709 71020170625: 711 The FreeBSD/powerpc platform now uses a 64-bit type for time_t. This is 712 a very major ABI incompatible change, so users of FreeBSD/powerpc must 713 be careful when performing source upgrades. It is best to run 714 'make installworld' from an alternate root system, either a live 715 CD/memory stick, or a temporary root partition. Additionally, all ports 716 must be recompiled. powerpc64 is largely unaffected, except in the case 717 of 32-bit compatibility. All 32-bit binaries will be affected. 718 71920170623: 720 Forward compatibility for the "ino64" project have been committed. This 721 will allow most new binaries to run on older kernels in a limited 722 fashion. This prevents many of the common foot-shooting actions in the 723 upgrade as well as the limited ability to roll back the kernel across 724 the ino64 upgrade. Complicated use cases may not work properly, though 725 enough simpler ones work to allow recovery in most situations. 726 72720170620: 728 Switch back to the BSDL dtc (Device Tree Compiler). Set WITH_GPL_DTC 729 if you require the GPL compiler. 730 73120170618: 732 The internal ABI used for communication between the NFS kernel modules 733 was changed by r320085, so __FreeBSD_version was bumped to 734 ensure all the NFS related modules are updated together. 735 73620170617: 737 The ABI of struct event was changed by extending the data 738 member to 64bit and adding ext fields. For upgrade, same 739 precautions as for the entry 20170523 "ino64" must be 740 followed. 741 74220170531: 743 The GNU roff toolchain has been removed from base. To render manpages 744 which are not supported by mandoc(1), man(1) can fallback on GNU roff 745 from ports (and recommends to install it). 746 To render roff(7) documents, consider using GNU roff from ports or the 747 heirloom doctools roff toolchain from ports via pkg install groff or 748 via pkg install heirloom-doctools. 749 75020170524: 751 The ath(4) and ath_hal(4) modules now build piecemeal to allow for 752 smaller runtime footprint builds. This is useful for embedded systems 753 which only require one chipset support. 754 755 If you load it as a module, make sure this is in /boot/loader.conf: 756 757 if_ath_load="YES" 758 759 This will load the HAL, all chip/RF backends and if_ath_pci. 760 If you have if_ath_pci in /boot/loader.conf, ensure it is after 761 if_ath or it will not load any HAL chipset support. 762 763 If you want to selectively load things (eg on ye cheape ARM/MIPS 764 platforms where RAM is at a premium) you should: 765 766 * load ath_hal 767 * load the chip modules in question 768 * load ath_rate, ath_dfs 769 * load ath_main 770 * load if_ath_pci and/or if_ath_ahb depending upon your particular 771 bus bind type - this is where probe/attach is done. 772 773 For further comments/feedback, poke adrian@ . 774 77520170523: 776 The "ino64" 64-bit inode project has been committed, which extends 777 a number of types to 64 bits. Upgrading in place requires care and 778 adherence to the documented upgrade procedure. 779 780 If using a custom kernel configuration ensure that the 781 COMPAT_FREEBSD11 option is included (as during the upgrade the 782 system will be running the ino64 kernel with the existing world). 783 784 For the safest in-place upgrade begin by removing previous build 785 artifacts via "rm -rf /usr/obj/*". Then, carefully follow the full 786 procedure documented below under the heading "To rebuild everything and 787 install it on the current system." Specifically, a reboot is required 788 after installing the new kernel before installing world. While an 789 installworld normally works by accident from multiuser after rebooting 790 the proper kernel, there are many cases where this will fail across this 791 upgrade and installworld from single user is required. 792 79320170424: 794 The NATM framework including the en(4), fatm(4), hatm(4), and 795 patm(4) devices has been removed. Consumers should plan a 796 migration before the end-of-life date for FreeBSD 11. 797 79820170420: 799 GNU diff has been replaced by a BSD licensed diff. Some features of GNU 800 diff has not been implemented, if those are needed a newer version of 801 GNU diff is available via the diffutils package under the gdiff name. 802 80320170413: 804 As of r316810 for ipfilter, keep frags is no longer assumed when 805 keep state is specified in a rule. r316810 aligns ipfilter with 806 documentation in man pages separating keep frags from keep state. 807 This allows keep state to be specified without forcing keep frags 808 and allows keep frags to be specified independently of keep state. 809 To maintain previous behaviour, also specify keep frags with 810 keep state (as documented in ipf.conf.5). 811 81220170407: 813 arm64 builds now use the base system LLD 4.0.0 linker by default, 814 instead of requiring that the aarch64-binutils port or package be 815 installed. To continue using aarch64-binutils, set 816 CROSS_BINUTILS_PREFIX=/usr/local/aarch64-freebsd/bin . 817 81820170405: 819 The UDP optimization in entry 20160818 that added the sysctl 820 net.inet.udp.require_l2_bcast has been reverted. L2 broadcast 821 packets will no longer be treated as L3 broadcast packets. 822 82320170331: 824 Binds and sends to the loopback addresses, IPv6 and IPv4, will now 825 use any explicitly assigned loopback address available in the jail 826 instead of using the first assigned address of the jail. 827 82820170329: 829 The ctl.ko module no longer implements the iSCSI target frontend: 830 cfiscsi.ko does instead. 831 832 If building cfiscsi.ko as a kernel module, the module can be loaded 833 via one of the following methods: 834 - `cfiscsi_load="YES"` in loader.conf(5). 835 - Add `cfiscsi` to `$kld_list` in rc.conf(5). 836 - ctladm(8)/ctld(8), when compiled with iSCSI support 837 (`WITH_ISCSI=yes` in src.conf(5)) 838 839 Please see cfiscsi(4) for more details. 840 84120170316: 842 The mmcsd.ko module now additionally depends on geom_flashmap.ko. 843 Also, mmc.ko and mmcsd.ko need to be a matching pair built from the 844 same source (previously, the dependency of mmcsd.ko on mmc.ko was 845 missing, but mmcsd.ko now will refuse to load if it is incompatible 846 with mmc.ko). 847 84820170315: 849 The syntax of ipfw(8) named states was changed to avoid ambiguity. 850 If you have used named states in the firewall rules, you need to modify 851 them after installworld and before rebooting. Now named states must 852 be prefixed with colon. 853 85420170311: 855 The old drm (sys/dev/drm/) drivers for i915 and radeon have been 856 removed as the userland we provide cannot use them. The KMS version 857 (sys/dev/drm2) supports the same hardware. 858 85920170302: 860 Clang, llvm, lldb, compiler-rt and libc++ have been upgraded to 4.0.0. 861 Please see the 20141231 entry below for information about prerequisites 862 and upgrading, if you are not already using clang 3.5.0 or higher. 863 86420170221: 865 The code that provides support for ZFS .zfs/ directory functionality 866 has been reimplemented. It's not possible now to create a snapshot 867 by mkdir under .zfs/snapshot/. That should be the only user visible 868 change. 869 87020170216: 871 EISA bus support has been removed. The WITH_EISA option is no longer 872 valid. 873 87420170215: 875 MCA bus support has been removed. 876 87720170127: 878 The WITH_LLD_AS_LD / WITHOUT_LLD_AS_LD build knobs have been renamed 879 WITH_LLD_IS_LD / WITHOUT_LLD_IS_LD, for consistency with CLANG_IS_CC. 880 88120170112: 882 The EM_MULTIQUEUE kernel configuration option is deprecated now that 883 the em(4) driver conforms to iflib specifications. 884 88520170109: 886 The igb(4), em(4) and lem(4) ethernet drivers are now implemented via 887 IFLIB. If you have a custom kernel configuration that excludes em(4) 888 but you use igb(4), you need to re-add em(4) to your custom 889 configuration. 890 89120161217: 892 Clang, llvm, lldb, compiler-rt and libc++ have been upgraded to 3.9.1. 893 Please see the 20141231 entry below for information about prerequisites 894 and upgrading, if you are not already using clang 3.5.0 or higher. 895 89620161124: 897 Clang, llvm, lldb, compiler-rt and libc++ have been upgraded to 3.9.0. 898 Please see the 20141231 entry below for information about prerequisites 899 and upgrading, if you are not already using clang 3.5.0 or higher. 900 90120161119: 902 The layout of the pmap structure has changed for powerpc to put the pmap 903 statistics at the front for all CPU variations. libkvm(3) and all tools 904 that link against it need to be recompiled. 905 90620161030: 907 isl(4) and cyapa(4) drivers now require a new driver, 908 chromebook_platform(4), to work properly on Chromebook-class hardware. 909 On other types of hardware the drivers may need to be configured using 910 device hints. Please see the corresponding manual pages for details. 911 91220161017: 913 The urtwn(4) driver was merged into rtwn(4) and now consists of 914 rtwn(4) main module + rtwn_usb(4) and rtwn_pci(4) bus-specific 915 parts. 916 Also, firmware for RTL8188CE was renamed due to possible name 917 conflict (rtwnrtl8192cU(B) -> rtwnrtl8192cE(B)) 918 91920161015: 920 GNU rcs has been removed from base. It is available as packages: 921 - rcs: Latest GPLv3 GNU rcs version. 922 - rcs57: Copy of the latest version of GNU rcs (GPLv2) before it was 923 removed from base. 924 92520161008: 926 Use of the cc_cdg, cc_chd, cc_hd, or cc_vegas congestion control 927 modules now requires that the kernel configuration contain the 928 TCP_HHOOK option. (This option is included in the GENERIC kernel.) 929 93020161003: 931 The WITHOUT_ELFCOPY_AS_OBJCOPY src.conf(5) knob has been retired. 932 ELF Tool Chain's elfcopy is always installed as /usr/bin/objcopy. 933 93420160924: 935 Relocatable object files with the extension of .So have been renamed 936 to use an extension of .pico instead. The purpose of this change is 937 to avoid a name clash with shared libraries on case-insensitive file 938 systems. On those file systems, foo.So is the same file as foo.so. 939 94020160918: 941 GNU rcs has been turned off by default. It can (temporarily) be built 942 again by adding WITH_RCS knob in src.conf. 943 Otherwise, GNU rcs is available from packages: 944 - rcs: Latest GPLv3 GNU rcs version. 945 - rcs57: Copy of the latest version of GNU rcs (GPLv2) from base. 946 94720160918: 948 The backup_uses_rcs functionality has been removed from rc.subr. 949 95020160908: 951 The queue(3) debugging macro, QUEUE_MACRO_DEBUG, has been split into 952 two separate components, QUEUE_MACRO_DEBUG_TRACE and 953 QUEUE_MACRO_DEBUG_TRASH. Define both for the original 954 QUEUE_MACRO_DEBUG behavior. 955 95620160824: 957 r304787 changed some ioctl interfaces between the iSCSI userspace 958 programs and the kernel. ctladm, ctld, iscsictl, and iscsid must be 959 rebuilt to work with new kernels. __FreeBSD_version has been bumped 960 to 1200005. 961 96220160818: 963 The UDP receive code has been updated to only treat incoming UDP 964 packets that were addressed to an L2 broadcast address as L3 965 broadcast packets. It is not expected that this will affect any 966 standards-conforming UDP application. The new behaviour can be 967 disabled by setting the sysctl net.inet.udp.require_l2_bcast to 968 0. 969 97020160818: 971 Remove the openbsd_poll system call. 972 __FreeBSD_version has been bumped because of this. 973 97420160708: 975 The stable/11 branch has been created from head@r302406. 976 97720160622: 978 The libc stub for the pipe(2) system call has been replaced with 979 a wrapper that calls the pipe2(2) system call and the pipe(2) 980 system call is now only implemented by the kernels that include 981 "options COMPAT_FREEBSD10" in their config file (this is the 982 default). Users should ensure that this option is enabled in 983 their kernel or upgrade userspace to r302092 before upgrading their 984 kernel. 985 98620160527: 987 CAM will now strip leading spaces from SCSI disks' serial numbers. 988 This will affect users who create UFS filesystems on SCSI disks using 989 those disk's diskid device nodes. For example, if /etc/fstab 990 previously contained a line like 991 "/dev/diskid/DISK-%20%20%20%20%20%20%20ABCDEFG0123456", you should 992 change it to "/dev/diskid/DISK-ABCDEFG0123456". Users of geom 993 transforms like gmirror may also be affected. ZFS users should 994 generally be fine. 995 99620160523: 997 The bitstring(3) API has been updated with new functionality and 998 improved performance. But it is binary-incompatible with the old API. 999 Objects built with the new headers may not be linked against objects 1000 built with the old headers. 1001 100220160520: 1003 The brk and sbrk functions have been removed from libc on arm64. 1004 Binutils from ports has been updated to not link to these 1005 functions and should be updated to the latest version before 1006 installing a new libc. 1007 100820160517: 1009 The armv6 port now defaults to hard float ABI. Limited support 1010 for running both hardfloat and soft float on the same system 1011 is available using the libraries installed with -DWITH_LIBSOFT. 1012 This has only been tested as an upgrade path for installworld 1013 and packages may fail or need manual intervention to run. New 1014 packages will be needed. 1015 1016 To update an existing self-hosted armv6hf system, you must add 1017 TARGET_ARCH=armv6 on the make command line for both the build 1018 and the install steps. 1019 102020160510: 1021 Kernel modules compiled outside of a kernel build now default to 1022 installing to /boot/modules instead of /boot/kernel. Many kernel 1023 modules built this way (such as those in ports) already overrode 1024 KMODDIR explicitly to install into /boot/modules. However, 1025 manually building and installing a module from /sys/modules will 1026 now install to /boot/modules instead of /boot/kernel. 1027 102820160414: 1029 The CAM I/O scheduler has been committed to the kernel. There should be 1030 no user visible impact. This does enable NCQ Trim on ada SSDs. While the 1031 list of known rogues that claim support for this but actually corrupt 1032 data is believed to be complete, be on the lookout for data 1033 corruption. The known rogue list is believed to be complete: 1034 1035 o Crucial MX100, M550 drives with MU01 firmware. 1036 o Micron M510 and M550 drives with MU01 firmware. 1037 o Micron M500 prior to MU07 firmware 1038 o Samsung 830, 840, and 850 all firmwares 1039 o FCCT M500 all firmwares 1040 1041 Crucial has firmware http://www.crucial.com/usa/en/support-ssd-firmware 1042 with working NCQ TRIM. For Micron branded drives, see your sales rep for 1043 updated firmware. Black listed drives will work correctly because these 1044 drives work correctly so long as no NCQ TRIMs are sent to them. Given 1045 this list is the same as found in Linux, it's believed there are no 1046 other rogues in the market place. All other models from the above 1047 vendors work. 1048 1049 To be safe, if you are at all concerned, you can quirk each of your 1050 drives to prevent NCQ from being sent by setting: 1051 kern.cam.ada.X.quirks="0x2" 1052 in loader.conf. If the drive requires the 4k sector quirk, set the 1053 quirks entry to 0x3. 1054 105520160330: 1056 The FAST_DEPEND build option has been removed and its functionality is 1057 now the one true way. The old mkdep(1) style of 'make depend' has 1058 been removed. See 20160311 for further details. 1059 106020160317: 1061 Resource range types have grown from unsigned long to uintmax_t. All 1062 drivers, and anything using libdevinfo, need to be recompiled. 1063 106420160311: 1065 WITH_FAST_DEPEND is now enabled by default for in-tree and out-of-tree 1066 builds. It no longer runs mkdep(1) during 'make depend', and the 1067 'make depend' stage can safely be skipped now as it is auto ran 1068 when building 'make all' and will generate all SRCS and DPSRCS before 1069 building anything else. Dependencies are gathered at compile time with 1070 -MF flags kept in separate .depend files per object file. Users should 1071 run 'make cleandepend' once if using -DNO_CLEAN to clean out older 1072 stale .depend files. 1073 107420160306: 1075 On amd64, clang 3.8.0 can now insert sections of type AMD64_UNWIND into 1076 kernel modules. Therefore, if you load any kernel modules at boot time, 1077 please install the boot loaders after you install the kernel, but before 1078 rebooting, e.g.: 1079 1080 make buildworld 1081 make buildkernel KERNCONF=YOUR_KERNEL_HERE 1082 make installkernel KERNCONF=YOUR_KERNEL_HERE 1083 make -C sys/boot install 1084 <reboot in single user> 1085 1086 Then follow the usual steps, described in the General Notes section, 1087 below. 1088 108920160305: 1090 Clang, llvm, lldb and compiler-rt have been upgraded to 3.8.0. Please 1091 see the 20141231 entry below for information about prerequisites and 1092 upgrading, if you are not already using clang 3.5.0 or higher. 1093 109420160301: 1095 The AIO subsystem is now a standard part of the kernel. The 1096 VFS_AIO kernel option and aio.ko kernel module have been removed. 1097 Due to stability concerns, asynchronous I/O requests are only 1098 permitted on sockets and raw disks by default. To enable 1099 asynchronous I/O requests on all file types, set the 1100 vfs.aio.enable_unsafe sysctl to a non-zero value. 1101 110220160226: 1103 The ELF object manipulation tool objcopy is now provided by the 1104 ELF Tool Chain project rather than by GNU binutils. It should be a 1105 drop-in replacement, with the addition of arm64 support. The 1106 (temporary) src.conf knob WITHOUT_ELFCOPY_AS_OBJCOPY knob may be set 1107 to obtain the GNU version if necessary. 1108 110920160129: 1110 Building ZFS pools on top of zvols is prohibited by default. That 1111 feature has never worked safely; it's always been prone to deadlocks. 1112 Using a zvol as the backing store for a VM guest's virtual disk will 1113 still work, even if the guest is using ZFS. Legacy behavior can be 1114 restored by setting vfs.zfs.vol.recursive=1. 1115 111620160119: 1117 The NONE and HPN patches has been removed from OpenSSH. They are 1118 still available in the security/openssh-portable port. 1119 112020160113: 1121 With the addition of ypldap(8), a new _ypldap user is now required 1122 during installworld. "mergemaster -p" can be used to add the user 1123 prior to installworld, as documented in the handbook. 1124 112520151216: 1126 The tftp loader (pxeboot) now uses the option root-path directive. As a 1127 consequence it no longer looks for a pxeboot.4th file on the tftp 1128 server. Instead it uses the regular /boot infrastructure as with the 1129 other loaders. 1130 113120151211: 1132 The code to start recording plug and play data into the modules has 1133 been committed. While the old tools will properly build a new kernel, 1134 a number of warnings about "unknown metadata record 4" will be produced 1135 for an older kldxref. To avoid such warnings, make sure to rebuild 1136 the kernel toolchain (or world). Make sure that you have r292078 or 1137 later when trying to build 292077 or later before rebuilding. 1138 113920151207: 1140 Debug data files are now built by default with 'make buildworld' and 1141 installed with 'make installworld'. This facilitates debugging but 1142 requires more disk space both during the build and for the installed 1143 world. Debug files may be disabled by setting WITHOUT_DEBUG_FILES=yes 1144 in src.conf(5). 1145 114620151130: 1147 r291527 changed the internal interface between the nfsd.ko and 1148 nfscommon.ko modules. As such, they must both be upgraded to-gether. 1149 __FreeBSD_version has been bumped because of this. 1150 115120151108: 1152 Add support for unicode collation strings leads to a change of 1153 order of files listed by ls(1) for example. To get back to the old 1154 behaviour, set LC_COLLATE environment variable to "C". 1155 1156 Databases administrators will need to reindex their databases given 1157 collation results will be different. 1158 1159 Due to a bug in install(1) it is recommended to remove the ancient 1160 locales before running make installworld. 1161 1162 rm -rf /usr/share/locale/* 1163 116420151030: 1165 The OpenSSL has been upgraded to 1.0.2d. Any binaries requiring 1166 libcrypto.so.7 or libssl.so.7 must be recompiled. 1167 116820151020: 1169 Qlogic 24xx/25xx firmware images were updated from 5.5.0 to 7.3.0. 1170 Kernel modules isp_2400_multi and isp_2500_multi were removed and 1171 should be replaced with isp_2400 and isp_2500 modules respectively. 1172 117320151017: 1174 The build previously allowed using 'make -n' to not recurse into 1175 sub-directories while showing what commands would be executed, and 1176 'make -n -n' to recursively show commands. Now 'make -n' will recurse 1177 and 'make -N' will not. 1178 117920151012: 1180 If you specify SENDMAIL_MC or SENDMAIL_CF in make.conf, mergemaster 1181 and etcupdate will now use this file. A custom sendmail.cf is now 1182 updated via this mechanism rather than via installworld. If you had 1183 excluded sendmail.cf in mergemaster.rc or etcupdate.conf, you may 1184 want to remove the exclusion or change it to "always install". 1185 /etc/mail/sendmail.cf is now managed the same way regardless of 1186 whether SENDMAIL_MC/SENDMAIL_CF is used. If you are not using 1187 SENDMAIL_MC/SENDMAIL_CF there should be no change in behavior. 1188 118920151011: 1190 Compatibility shims for legacy ATA device names have been removed. 1191 It includes ATA_STATIC_ID kernel option, kern.cam.ada.legacy_aliases 1192 and kern.geom.raid.legacy_aliases loader tunables, kern.devalias.* 1193 environment variables, /dev/ad* and /dev/ar* symbolic links. 1194 119520151006: 1196 Clang, llvm, lldb, compiler-rt and libc++ have been upgraded to 3.7.0. 1197 Please see the 20141231 entry below for information about prerequisites 1198 and upgrading, if you are not already using clang 3.5.0 or higher. 1199 120020150924: 1201 Kernel debug files have been moved to /usr/lib/debug/boot/kernel/, 1202 and renamed from .symbols to .debug. This reduces the size requirements 1203 on the boot partition or file system and provides consistency with 1204 userland debug files. 1205 1206 When using the supported kernel installation method the 1207 /usr/lib/debug/boot/kernel directory will be renamed (to kernel.old) 1208 as is done with /boot/kernel. 1209 1210 Developers wishing to maintain the historical behavior of installing 1211 debug files in /boot/kernel/ can set KERN_DEBUGDIR="" in src.conf(5). 1212 121320150827: 1214 The wireless drivers had undergone changes that remove the 'parent 1215 interface' from the ifconfig -l output. The rc.d network scripts 1216 used to check presence of a parent interface in the list, so old 1217 scripts would fail to start wireless networking. Thus, etcupdate(3) 1218 or mergemaster(8) run is required after kernel update, to update your 1219 rc.d scripts in /etc. 1220 122120150827: 1222 pf no longer supports 'scrub fragment crop' or 'scrub fragment drop-ovl' 1223 These configurations are now automatically interpreted as 1224 'scrub fragment reassemble'. 1225 122620150817: 1227 Kernel-loadable modules for the random(4) device are back. To use 1228 them, the kernel must have 1229 1230 device random 1231 options RANDOM_LOADABLE 1232 1233 kldload(8) can then be used to load random_fortuna.ko 1234 or random_yarrow.ko. Please note that due to the indirect 1235 function calls that the loadable modules need to provide, 1236 the build-in variants will be slightly more efficient. 1237 1238 The random(4) kernel option RANDOM_DUMMY has been retired due to 1239 unpopularity. It was not all that useful anyway. 1240 124120150813: 1242 The WITHOUT_ELFTOOLCHAIN_TOOLS src.conf(5) knob has been retired. 1243 Control over building the ELF Tool Chain tools is now provided by 1244 the WITHOUT_TOOLCHAIN knob. 1245 124620150810: 1247 The polarity of Pulse Per Second (PPS) capture events with the 1248 uart(4) driver has been corrected. Prior to this change the PPS 1249 "assert" event corresponded to the trailing edge of a positive PPS 1250 pulse and the "clear" event was the leading edge of the next pulse. 1251 1252 As the width of a PPS pulse in a typical GPS receiver is on the 1253 order of 1 millisecond, most users will not notice any significant 1254 difference with this change. 1255 1256 Anyone who has compensated for the historical polarity reversal by 1257 configuring a negative offset equal to the pulse width will need to 1258 remove that workaround. 1259 126020150809: 1261 The default group assigned to /dev/dri entries has been changed 1262 from 'wheel' to 'video' with the id of '44'. If you want to have 1263 access to the dri devices please add yourself to the video group 1264 with: 1265 1266 # pw groupmod video -m $USER 1267 126820150806: 1269 The menu.rc and loader.rc files will now be replaced during 1270 upgrades. Please migrate local changes to menu.rc.local and 1271 loader.rc.local instead. 1272 127320150805: 1274 GNU Binutils versions of addr2line, c++filt, nm, readelf, size, 1275 strings and strip have been removed. The src.conf(5) knob 1276 WITHOUT_ELFTOOLCHAIN_TOOLS no longer provides the binutils tools. 1277 127820150728: 1279 As ZFS requires more kernel stack pages than is the default on some 1280 architectures e.g. i386, it now warns if KSTACK_PAGES is less than 1281 ZFS_MIN_KSTACK_PAGES (which is 4 at the time of writing). 1282 1283 Please consider using 'options KSTACK_PAGES=X' where X is greater 1284 than or equal to ZFS_MIN_KSTACK_PAGES i.e. 4 in such configurations. 1285 128620150706: 1287 sendmail has been updated to 8.15.2. Starting with FreeBSD 11.0 1288 and sendmail 8.15, sendmail uses uncompressed IPv6 addresses by 1289 default, i.e., they will not contain "::". For example, instead 1290 of ::1, it will be 0:0:0:0:0:0:0:1. This permits a zero subnet 1291 to have a more specific match, such as different map entries for 1292 IPv6:0:0 vs IPv6:0. This change requires that configuration 1293 data (including maps, files, classes, custom ruleset, etc.) must 1294 use the same format, so make certain such configuration data is 1295 upgrading. As a very simple check search for patterns like 1296 'IPv6:[0-9a-fA-F:]*::' and 'IPv6::'. To return to the old 1297 behavior, set the m4 option confUSE_COMPRESSED_IPV6_ADDRESSES or 1298 the cf option UseCompressedIPv6Addresses. 1299 130020150630: 1301 The default kernel entropy-processing algorithm is now 1302 Fortuna, replacing Yarrow. 1303 1304 Assuming you have 'device random' in your kernel config 1305 file, the configurations allow a kernel option to override 1306 this default. You may choose *ONE* of: 1307 1308 options RANDOM_YARROW # Legacy /dev/random algorithm. 1309 options RANDOM_DUMMY # Blocking-only driver. 1310 1311 If you have neither, you get Fortuna. For most people, 1312 read no further, Fortuna will give a /dev/random that works 1313 like it always used to, and the difference will be irrelevant. 1314 1315 If you remove 'device random', you get *NO* kernel-processed 1316 entropy at all. This may be acceptable to folks building 1317 embedded systems, but has complications. Carry on reading, 1318 and it is assumed you know what you need. 1319 1320 *PLEASE* read random(4) and random(9) if you are in the 1321 habit of tweaking kernel configs, and/or if you are a member 1322 of the embedded community, wanting specific and not-usual 1323 behaviour from your security subsystems. 1324 1325 NOTE!! If you use RANDOM_DUMMY and/or have no 'device 1326 random', you will NOT have a functioning /dev/random, and 1327 many cryptographic features will not work, including SSH. 1328 You may also find strange behaviour from the random(3) set 1329 of library functions, in particular sranddev(3), srandomdev(3) 1330 and arc4random(3). The reason for this is that the KERN_ARND 1331 sysctl only returns entropy if it thinks it has some to 1332 share, and with RANDOM_DUMMY or no 'device random' this 1333 will never happen. 1334 133520150623: 1336 An additional fix for the issue described in the 20150614 sendmail 1337 entry below has been committed in revision 284717. 1338 133920150616: 1340 FreeBSD's old make (fmake) has been removed from the system. It is 1341 available as the devel/fmake port or via pkg install fmake. 1342 134320150615: 1344 The fix for the issue described in the 20150614 sendmail entry 1345 below has been committed in revision 284436. The work 1346 around described in that entry is no longer needed unless the 1347 default setting is overridden by a confDH_PARAMETERS configuration 1348 setting of '5' or pointing to a 512 bit DH parameter file. 1349 135020150614: 1351 ALLOW_DEPRECATED_ATF_TOOLS/ATFFILE support has been removed from 1352 atf.test.mk (included from bsd.test.mk). Please upgrade devel/atf 1353 and devel/kyua to version 0.20+ and adjust any calling code to work 1354 with Kyuafile and kyua. 1355 135620150614: 1357 The import of openssl to address the FreeBSD-SA-15:10.openssl 1358 security advisory includes a change which rejects handshakes 1359 with DH parameters below 768 bits. sendmail releases prior 1360 to 8.15.2 (not yet released), defaulted to a 512 bit 1361 DH parameter setting for client connections. To work around 1362 this interoperability, sendmail can be configured to use a 1363 2048 bit DH parameter by: 1364 1365 1. Edit /etc/mail/`hostname`.mc 1366 2. If a setting for confDH_PARAMETERS does not exist or 1367 exists and is set to a string beginning with '5', 1368 replace it with '2'. 1369 3. If a setting for confDH_PARAMETERS exists and is set to 1370 a file path, create a new file with: 1371 openssl dhparam -out /path/to/file 2048 1372 4. Rebuild the .cf file: 1373 cd /etc/mail/; make; make install 1374 5. Restart sendmail: 1375 cd /etc/mail/; make restart 1376 1377 A sendmail patch is coming, at which time this file will be 1378 updated. 1379 138020150604: 1381 Generation of legacy formatted entries have been disabled by default 1382 in pwd_mkdb(8), as all base system consumers of the legacy formatted 1383 entries were converted to use the new format by default when the new, 1384 machine independent format have been added and supported since FreeBSD 1385 5.x. 1386 1387 Please see the pwd_mkdb(8) manual page for further details. 1388 138920150525: 1390 Clang and llvm have been upgraded to 3.6.1 release. Please see the 1391 20141231 entry below for information about prerequisites and upgrading, 1392 if you are not already using 3.5.0 or higher. 1393 139420150521: 1395 TI platform code switched to using vendor DTS files and this update 1396 may break existing systems running on Beaglebone, Beaglebone Black, 1397 and Pandaboard: 1398 1399 - dtb files should be regenerated/reinstalled. Filenames are the 1400 same but content is different now 1401 - GPIO addressing was changed, now each GPIO bank (32 pins per bank) 1402 has its own /dev/gpiocX device, e.g. pin 121 on /dev/gpioc0 in old 1403 addressing scheme is now pin 25 on /dev/gpioc3. 1404 - Pandaboard: /etc/ttys should be updated, serial console device is 1405 now /dev/ttyu2, not /dev/ttyu0 1406 140720150501: 1408 soelim(1) from gnu/usr.bin/groff has been replaced by usr.bin/soelim. 1409 If you need the GNU extension from groff soelim(1), install groff 1410 from package: pkg install groff, or via ports: textproc/groff. 1411 141220150423: 1413 chmod, chflags, chown and chgrp now affect symlinks in -R mode as 1414 defined in symlink(7); previously symlinks were silently ignored. 1415 141620150415: 1417 The const qualifier has been removed from iconv(3) to comply with 1418 POSIX. The ports tree is aware of this from r384038 onwards. 1419 142020150416: 1421 Libraries specified by LIBADD in Makefiles must have a corresponding 1422 DPADD_<lib> variable to ensure correct dependencies. This is now 1423 enforced in src.libnames.mk. 1424 142520150324: 1426 From legacy ata(4) driver was removed support for SATA controllers 1427 supported by more functional drivers ahci(4), siis(4) and mvs(4). 1428 Kernel modules ataahci and ataadaptec were removed completely, 1429 replaced by ahci and mvs modules respectively. 1430 143120150315: 1432 Clang, llvm and lldb have been upgraded to 3.6.0 release. Please see 1433 the 20141231 entry below for information about prerequisites and 1434 upgrading, if you are not already using 3.5.0 or higher. 1435 143620150307: 1437 The 32-bit PowerPC kernel has been changed to a position-independent 1438 executable. This can only be booted with a version of loader(8) 1439 newer than January 31, 2015, so make sure to update both world and 1440 kernel before rebooting. 1441 144220150217: 1443 If you are running a -CURRENT kernel since r273872 (Oct 30th, 2014), 1444 but before r278950, the RNG was not seeded properly. Immediately 1445 upgrade the kernel to r278950 or later and regenerate any keys (e.g. 1446 ssh keys or openssl keys) that were generated w/ a kernel from that 1447 range. This does not affect programs that directly used /dev/random 1448 or /dev/urandom. All userland uses of arc4random(3) are affected. 1449 145020150210: 1451 The autofs(4) ABI was changed in order to restore binary compatibility 1452 with 10.1-RELEASE. The automountd(8) daemon needs to be rebuilt to work 1453 with the new kernel. 1454 145520150131: 1456 The powerpc64 kernel has been changed to a position-independent 1457 executable. This can only be booted with a new version of loader(8), 1458 so make sure to update both world and kernel before rebooting. 1459 146020150118: 1461 Clang and llvm have been upgraded to 3.5.1 release. This is a bugfix 1462 only release, no new features have been added. Please see the 20141231 1463 entry below for information about prerequisites and upgrading, if you 1464 are not already using 3.5.0. 1465 146620150107: 1467 ELF tools addr2line, elfcopy (strip), nm, size, and strings are now 1468 taken from the ELF Tool Chain project rather than GNU binutils. They 1469 should be drop-in replacements, with the addition of arm64 support. 1470 The WITHOUT_ELFTOOLCHAIN_TOOLS= knob may be used to obtain the 1471 binutils tools, if necessary. See 20150805 for updated information. 1472 147320150105: 1474 The default Unbound configuration now enables remote control 1475 using a local socket. Users who have already enabled the 1476 local_unbound service should regenerate their configuration 1477 by running "service local_unbound setup" as root. 1478 147920150102: 1480 The GNU texinfo and GNU info pages have been removed. 1481 To be able to view GNU info pages please install texinfo from ports. 1482 148320141231: 1484 Clang, llvm and lldb have been upgraded to 3.5.0 release. 1485 1486 As of this release, a prerequisite for building clang, llvm and lldb is 1487 a C++11 capable compiler and C++11 standard library. This means that to 1488 be able to successfully build the cross-tools stage of buildworld, with 1489 clang as the bootstrap compiler, your system compiler or cross compiler 1490 should either be clang 3.3 or later, or gcc 4.8 or later, and your 1491 system C++ library should be libc++, or libdstdc++ from gcc 4.8 or 1492 later. 1493 1494 On any standard FreeBSD 10.x or 11.x installation, where clang and 1495 libc++ are on by default (that is, on x86 or arm), this should work out 1496 of the box. 1497 1498 On 9.x installations where clang is enabled by default, e.g. on x86 and 1499 powerpc, libc++ will not be enabled by default, so libc++ should be 1500 built (with clang) and installed first. If both clang and libc++ are 1501 missing, build clang first, then use it to build libc++. 1502 1503 On 8.x and earlier installations, upgrade to 9.x first, and then follow 1504 the instructions for 9.x above. 1505 1506 Sparc64 and mips users are unaffected, as they still use gcc 4.2.1 by 1507 default, and do not build clang. 1508 1509 Many embedded systems are resource constrained, and will not be able to 1510 build clang in a reasonable time, or in some cases at all. In those 1511 cases, cross building bootable systems on amd64 is a workaround. 1512 1513 This new version of clang introduces a number of new warnings, of which 1514 the following are most likely to appear: 1515 1516 -Wabsolute-value 1517 1518 This warns in two cases, for both C and C++: 1519 * When the code is trying to take the absolute value of an unsigned 1520 quantity, which is effectively a no-op, and almost never what was 1521 intended. The code should be fixed, if at all possible. If you are 1522 sure that the unsigned quantity can be safely cast to signed, without 1523 loss of information or undefined behavior, you can add an explicit 1524 cast, or disable the warning. 1525 1526 * When the code is trying to take an absolute value, but the called 1527 abs() variant is for the wrong type, which can lead to truncation. 1528 If you want to disable the warning instead of fixing the code, please 1529 make sure that truncation will not occur, or it might lead to unwanted 1530 side-effects. 1531 1532 -Wtautological-undefined-compare and 1533 -Wundefined-bool-conversion 1534 1535 These warn when C++ code is trying to compare 'this' against NULL, while 1536 'this' should never be NULL in well-defined C++ code. However, there is 1537 some legacy (pre C++11) code out there, which actively abuses this 1538 feature, which was less strictly defined in previous C++ versions. 1539 1540 Squid and openjdk do this, for example. The warning can be turned off 1541 for C++98 and earlier, but compiling the code in C++11 mode might result 1542 in unexpected behavior; for example, the parts of the program that are 1543 unreachable could be optimized away. 1544 154520141222: 1546 The old NFS client and server (kernel options NFSCLIENT, NFSSERVER) 1547 kernel sources have been removed. The .h files remain, since some 1548 utilities include them. This will need to be fixed later. 1549 If "mount -t oldnfs ..." is attempted, it will fail. 1550 If the "-o" option on mountd(8), nfsd(8) or nfsstat(1) is used, 1551 the utilities will report errors. 1552 155320141121: 1554 The handling of LOCAL_LIB_DIRS has been altered to skip addition of 1555 directories to top level SUBDIR variable when their parent 1556 directory is included in LOCAL_DIRS. Users with build systems with 1557 such hierarchies and without SUBDIR entries in the parent 1558 directory Makefiles should add them or add the directories to 1559 LOCAL_DIRS. 1560 156120141109: 1562 faith(4) and faithd(8) have been removed from the base system. Faith 1563 has been obsolete for a very long time. 1564 156520141104: 1566 vt(4), the new console driver, is enabled by default. It brings 1567 support for Unicode and double-width characters, as well as 1568 support for UEFI and integration with the KMS kernel video 1569 drivers. 1570 1571 You may need to update your console settings in /etc/rc.conf, 1572 most probably the keymap. During boot, /etc/rc.d/syscons will 1573 indicate what you need to do. 1574 1575 vt(4) still has issues and lacks some features compared to 1576 syscons(4). See the wiki for up-to-date information: 1577 https://wiki.freebsd.org/Newcons 1578 1579 If you want to keep using syscons(4), you can do so by adding 1580 the following line to /boot/loader.conf: 1581 kern.vty=sc 1582 158320141102: 1584 pjdfstest has been integrated into kyua as an opt-in test suite. 1585 Please see share/doc/pjdfstest/README for more details on how to 1586 execute it. 1587 158820141009: 1589 gperf has been removed from the base system for architectures 1590 that use clang. Ports that require gperf will obtain it from the 1591 devel/gperf port. 1592 159320140923: 1594 pjdfstest has been moved from tools/regression/pjdfstest to 1595 contrib/pjdfstest . 1596 159720140922: 1598 At svn r271982, The default linux compat kernel ABI has been adjusted 1599 to 2.6.18 in support of the linux-c6 compat ports infrastructure 1600 update. If you wish to continue using the linux-f10 compat ports, 1601 add compat.linux.osrelease=2.6.16 to your local sysctl.conf. Users are 1602 encouraged to update their linux-compat packages to linux-c6 during 1603 their next update cycle. 1604 160520140729: 1606 The ofwfb driver, used to provide a graphics console on PowerPC when 1607 using vt(4), no longer allows mmap() of all physical memory. This 1608 will prevent Xorg on PowerPC with some ATI graphics cards from 1609 initializing properly unless x11-servers/xorg-server is updated to 1610 1.12.4_8 or newer. 1611 161220140723: 1613 The xdev targets have been converted to using TARGET and 1614 TARGET_ARCH instead of XDEV and XDEV_ARCH. 1615 161620140719: 1617 The default unbound configuration has been modified to address 1618 issues with reverse lookups on networks that use private 1619 address ranges. If you use the local_unbound service, run 1620 "service local_unbound setup" as root to regenerate your 1621 configuration, then "service local_unbound reload" to load the 1622 new configuration. 1623 162420140709: 1625 The GNU texinfo and GNU info pages are not built and installed 1626 anymore, WITH_INFO knob has been added to allow to built and install 1627 them again. 1628 UPDATE: see 20150102 entry on texinfo's removal 1629 163020140708: 1631 The GNU readline library is now an INTERNALLIB - that is, it is 1632 statically linked into consumers (GDB and variants) in the base 1633 system, and the shared library is no longer installed. The 1634 devel/readline port is available for third party software that 1635 requires readline. 1636 163720140702: 1638 The Itanium architecture (ia64) has been removed from the list of 1639 known architectures. This is the first step in the removal of the 1640 architecture. 1641 164220140701: 1643 Commit r268115 has added NFSv4.1 server support, merged from 1644 projects/nfsv4.1-server. Since this includes changes to the 1645 internal interfaces between the NFS related modules, a full 1646 build of the kernel and modules will be necessary. 1647 __FreeBSD_version has been bumped. 1648 164920140629: 1650 The WITHOUT_VT_SUPPORT kernel config knob has been renamed 1651 WITHOUT_VT. (The other _SUPPORT knobs have a consistent meaning 1652 which differs from the behaviour controlled by this knob.) 1653 165420140619: 1655 Maximal length of the serial number in CTL was increased from 16 to 1656 64 chars, that breaks ABI. All CTL-related tools, such as ctladm 1657 and ctld, need to be rebuilt to work with a new kernel. 1658 165920140606: 1660 The libatf-c and libatf-c++ major versions were downgraded to 0 and 1661 1 respectively to match the upstream numbers. They were out of 1662 sync because, when they were originally added to FreeBSD, the 1663 upstream versions were not respected. These libraries are private 1664 and not yet built by default, so renumbering them should be a 1665 non-issue. However, unclean source trees will yield broken test 1666 programs once the operator executes "make delete-old-libs" after a 1667 "make installworld". 1668 1669 Additionally, the atf-sh binary was made private by moving it into 1670 /usr/libexec/. Already-built shell test programs will keep the 1671 path to the old binary so they will break after "make delete-old" 1672 is run. 1673 1674 If you are using WITH_TESTS=yes (not the default), wipe the object 1675 tree and rebuild from scratch to prevent spurious test failures. 1676 This is only needed once: the misnumbered libraries and misplaced 1677 binaries have been added to OptionalObsoleteFiles.inc so they will 1678 be removed during a clean upgrade. 1679 168020140512: 1681 Clang and llvm have been upgraded to 3.4.1 release. 1682 168320140508: 1684 We bogusly installed src.opts.mk in /usr/share/mk. This file should 1685 be removed to avoid issues in the future (and has been added to 1686 ObsoleteFiles.inc). 1687 168820140505: 1689 /etc/src.conf now affects only builds of the FreeBSD src tree. In the 1690 past, it affected all builds that used the bsd.*.mk files. The old 1691 behavior was a bug, but people may have relied upon it. To get this 1692 behavior back, you can .include /etc/src.conf from /etc/make.conf 1693 (which is still global and isn't changed). This also changes the 1694 behavior of incremental builds inside the tree of individual 1695 directories. Set MAKESYSPATH to ".../share/mk" to do that. 1696 Although this has survived make universe and some upgrade scenarios, 1697 other upgrade scenarios may have broken. At least one form of 1698 temporary breakage was fixed with MAKESYSPATH settings for buildworld 1699 as well... In cases where MAKESYSPATH isn't working with this 1700 setting, you'll need to set it to the full path to your tree. 1701 1702 One side effect of all this cleaning up is that bsd.compiler.mk 1703 is no longer implicitly included by bsd.own.mk. If you wish to 1704 use COMPILER_TYPE, you must now explicitly include bsd.compiler.mk 1705 as well. 1706 170720140430: 1708 The lindev device has been removed since /dev/full has been made a 1709 standard device. __FreeBSD_version has been bumped. 1710 171120140424: 1712 The knob WITHOUT_VI was added to the base system, which controls 1713 building ex(1), vi(1), etc. Older releases of FreeBSD required ex(1) 1714 in order to reorder files share/termcap and didn't build ex(1) as a 1715 build tool, so building/installing with WITH_VI is highly advised for 1716 build hosts for older releases. 1717 1718 This issue has been fixed in stable/9 and stable/10 in r277022 and 1719 r276991, respectively. 1720 172120140418: 1722 The YES_HESIOD knob has been removed. It has been obsolete for 1723 a decade. Please move to using WITH_HESIOD instead or your builds 1724 will silently lack HESIOD. 1725 172620140405: 1727 The uart(4) driver has been changed with respect to its handling 1728 of the low-level console. Previously the uart(4) driver prevented 1729 any process from changing the baudrate or the CLOCAL and HUPCL 1730 control flags. By removing the restrictions, operators can make 1731 changes to the serial console port without having to reboot. 1732 However, when getty(8) is started on the serial device that is 1733 associated with the low-level console, a misconfigured terminal 1734 line in /etc/ttys will now have a real impact. 1735 Before upgrading the kernel, make sure that /etc/ttys has the 1736 serial console device configured as 3wire without baudrate to 1737 preserve the previous behaviour. E.g: 1738 ttyu0 "/usr/libexec/getty 3wire" vt100 on secure 1739 174020140306: 1741 Support for libwrap (TCP wrappers) in rpcbind was disabled by default 1742 to improve performance. To re-enable it, if needed, run rpcbind 1743 with command line option -W. 1744 174520140226: 1746 Switched back to the GPL dtc compiler due to updates in the upstream 1747 dts files not being supported by the BSDL dtc compiler. You will need 1748 to rebuild your kernel toolchain to pick up the new compiler. Core dumps 1749 may result while building dtb files during a kernel build if you fail 1750 to do so. Set WITHOUT_GPL_DTC if you require the BSDL compiler. 1751 175220140216: 1753 Clang and llvm have been upgraded to 3.4 release. 1754 175520140216: 1756 The nve(4) driver has been removed. Please use the nfe(4) driver 1757 for NVIDIA nForce MCP Ethernet adapters instead. 1758 175920140212: 1760 An ABI incompatibility crept into the libc++ 3.4 import in r261283. 1761 This could cause certain C++ applications using shared libraries built 1762 against the previous version of libc++ to crash. The incompatibility 1763 has now been fixed, but any C++ applications or shared libraries built 1764 between r261283 and r261801 should be recompiled. 1765 176620140204: 1767 OpenSSH will now ignore errors caused by kernel lacking of Capsicum 1768 capability mode support. Please note that enabling the feature in 1769 kernel is still highly recommended. 1770 177120140131: 1772 OpenSSH is now built with sandbox support, and will use sandbox as 1773 the default privilege separation method. This requires Capsicum 1774 capability mode support in kernel. 1775 177620140128: 1777 The libelf and libdwarf libraries have been updated to newer 1778 versions from upstream. Shared library version numbers for 1779 these two libraries were bumped. Any ports or binaries 1780 requiring these two libraries should be recompiled. 1781 __FreeBSD_version is bumped to 1100006. 1782 178320140110: 1784 If a Makefile in a tests/ directory was auto-generating a Kyuafile 1785 instead of providing an explicit one, this would prevent such 1786 Makefile from providing its own Kyuafile in the future during 1787 NO_CLEAN builds. This has been fixed in the Makefiles but manual 1788 intervention is needed to clean an objdir if you use NO_CLEAN: 1789 # find /usr/obj -name Kyuafile | xargs rm -f 1790 179120131213: 1792 The behavior of gss_pseudo_random() for the krb5 mechanism 1793 has changed, for applications requesting a longer random string 1794 than produced by the underlying enctype's pseudo-random() function. 1795 In particular, the random string produced from a session key of 1796 enctype aes256-cts-hmac-sha1-96 or aes256-cts-hmac-sha1-96 will 1797 be different at the 17th octet and later, after this change. 1798 The counter used in the PRF+ construction is now encoded as a 1799 big-endian integer in accordance with RFC 4402. 1800 __FreeBSD_version is bumped to 1100004. 1801 180220131108: 1803 The WITHOUT_ATF build knob has been removed and its functionality 1804 has been subsumed into the more generic WITHOUT_TESTS. If you were 1805 using the former to disable the build of the ATF libraries, you 1806 should change your settings to use the latter. 1807 180820131025: 1809 The default version of mtree is nmtree which is obtained from 1810 NetBSD. The output is generally the same, but may vary 1811 slightly. If you found you need identical output adding 1812 "-F freebsd9" to the command line should do the trick. For the 1813 time being, the old mtree is available as fmtree. 1814 181520131014: 1816 libbsdyml has been renamed to libyaml and moved to /usr/lib/private. 1817 This will break ports-mgmt/pkg. Rebuild the port, or upgrade to pkg 1818 1.1.4_8 and verify bsdyml not linked in, before running "make 1819 delete-old-libs": 1820 # make -C /usr/ports/ports-mgmt/pkg build deinstall install clean 1821 or 1822 # pkg install pkg; ldd /usr/local/sbin/pkg | grep bsdyml 1823 182420131010: 1825 The stable/10 branch has been created in subversion from head 1826 revision r256279. 1827 1828COMMON ITEMS: 1829 1830 General Notes 1831 ------------- 1832 Avoid using make -j when upgrading. While generally safe, there are 1833 sometimes problems using -j to upgrade. If your upgrade fails with 1834 -j, please try again without -j. From time to time in the past there 1835 have been problems using -j with buildworld and/or installworld. This 1836 is especially true when upgrading between "distant" versions (eg one 1837 that cross a major release boundary or several minor releases, or when 1838 several months have passed on the -current branch). 1839 1840 Sometimes, obscure build problems are the result of environment 1841 poisoning. This can happen because the make utility reads its 1842 environment when searching for values for global variables. To run 1843 your build attempts in an "environmental clean room", prefix all make 1844 commands with 'env -i '. See the env(1) manual page for more details. 1845 1846 When upgrading from one major version to another it is generally best to 1847 upgrade to the latest code in the currently installed branch first, then 1848 do an upgrade to the new branch. This is the best-tested upgrade path, 1849 and has the highest probability of being successful. Please try this 1850 approach if you encounter problems with a major version upgrade. Since 1851 the stable 4.x branch point, one has generally been able to upgrade from 1852 anywhere in the most recent stable branch to head / current (or even the 1853 last couple of stable branches). See the top of this file when there's 1854 an exception. 1855 1856 When upgrading a live system, having a root shell around before 1857 installing anything can help undo problems. Not having a root shell 1858 around can lead to problems if pam has changed too much from your 1859 starting point to allow continued authentication after the upgrade. 1860 1861 This file should be read as a log of events. When a later event changes 1862 information of a prior event, the prior event should not be deleted. 1863 Instead, a pointer to the entry with the new information should be 1864 placed in the old entry. Readers of this file should also sanity check 1865 older entries before relying on them blindly. Authors of new entries 1866 should write them with this in mind. 1867 1868 ZFS notes 1869 --------- 1870 When upgrading the boot ZFS pool to a new version, always follow 1871 these two steps: 1872 1873 1.) recompile and reinstall the ZFS boot loader and boot block 1874 (this is part of "make buildworld" and "make installworld") 1875 1876 2.) update the ZFS boot block on your boot drive 1877 1878 The following example updates the ZFS boot block on the first 1879 partition (freebsd-boot) of a GPT partitioned drive ada0: 1880 "gpart bootcode -p /boot/gptzfsboot -i 1 ada0" 1881 1882 Non-boot pools do not need these updates. 1883 1884 To build a kernel 1885 ----------------- 1886 If you are updating from a prior version of FreeBSD (even one just 1887 a few days old), you should follow this procedure. It is the most 1888 failsafe as it uses a /usr/obj tree with a fresh mini-buildworld, 1889 1890 make kernel-toolchain 1891 make -DALWAYS_CHECK_MAKE buildkernel KERNCONF=YOUR_KERNEL_HERE 1892 make -DALWAYS_CHECK_MAKE installkernel KERNCONF=YOUR_KERNEL_HERE 1893 1894 To test a kernel once 1895 --------------------- 1896 If you just want to boot a kernel once (because you are not sure 1897 if it works, or if you want to boot a known bad kernel to provide 1898 debugging information) run 1899 make installkernel KERNCONF=YOUR_KERNEL_HERE KODIR=/boot/testkernel 1900 nextboot -k testkernel 1901 1902 To rebuild everything and install it on the current system. 1903 ----------------------------------------------------------- 1904 # Note: sometimes if you are running current you gotta do more than 1905 # is listed here if you are upgrading from a really old current. 1906 1907 <make sure you have good level 0 dumps> 1908 make buildworld 1909 make buildkernel KERNCONF=YOUR_KERNEL_HERE 1910 make installkernel KERNCONF=YOUR_KERNEL_HERE 1911 [1] 1912 <reboot in single user> [3] 1913 mergemaster -Fp [5] 1914 make installworld 1915 mergemaster -Fi [4] 1916 make delete-old [6] 1917 <reboot> 1918 1919 To cross-install current onto a separate partition 1920 -------------------------------------------------- 1921 # In this approach we use a separate partition to hold 1922 # current's root, 'usr', and 'var' directories. A partition 1923 # holding "/", "/usr" and "/var" should be about 2GB in 1924 # size. 1925 1926 <make sure you have good level 0 dumps> 1927 <boot into -stable> 1928 make buildworld 1929 make buildkernel KERNCONF=YOUR_KERNEL_HERE 1930 <maybe newfs current's root partition> 1931 <mount current's root partition on directory ${CURRENT_ROOT}> 1932 make installworld DESTDIR=${CURRENT_ROOT} -DDB_FROM_SRC 1933 make distribution DESTDIR=${CURRENT_ROOT} # if newfs'd 1934 make installkernel KERNCONF=YOUR_KERNEL_HERE DESTDIR=${CURRENT_ROOT} 1935 cp /etc/fstab ${CURRENT_ROOT}/etc/fstab # if newfs'd 1936 <edit ${CURRENT_ROOT}/etc/fstab to mount "/" from the correct partition> 1937 <reboot into current> 1938 <do a "native" rebuild/install as described in the previous section> 1939 <maybe install compatibility libraries from ports/misc/compat*> 1940 <reboot> 1941 1942 1943 To upgrade in-place from stable to current 1944 ---------------------------------------------- 1945 <make sure you have good level 0 dumps> 1946 make buildworld [9] 1947 make buildkernel KERNCONF=YOUR_KERNEL_HERE [8] 1948 make installkernel KERNCONF=YOUR_KERNEL_HERE 1949 [1] 1950 <reboot in single user> [3] 1951 mergemaster -Fp [5] 1952 make installworld 1953 mergemaster -Fi [4] 1954 make delete-old [6] 1955 <reboot> 1956 1957 Make sure that you've read the UPDATING file to understand the 1958 tweaks to various things you need. At this point in the life 1959 cycle of current, things change often and you are on your own 1960 to cope. The defaults can also change, so please read ALL of 1961 the UPDATING entries. 1962 1963 Also, if you are tracking -current, you must be subscribed to 1964 freebsd-current@freebsd.org. Make sure that before you update 1965 your sources that you have read and understood all the recent 1966 messages there. If in doubt, please track -stable which has 1967 much fewer pitfalls. 1968 1969 [1] If you have third party modules, such as vmware, you 1970 should disable them at this point so they don't crash your 1971 system on reboot. 1972 1973 [3] From the bootblocks, boot -s, and then do 1974 fsck -p 1975 mount -u / 1976 mount -a 1977 sh /etc/rc.d/zfs start # mount zfs filesystem, if needed 1978 cd src # full path to source 1979 adjkerntz -i # if CMOS is wall time 1980 Also, when doing a major release upgrade, it is required that 1981 you boot into single user mode to do the installworld. 1982 1983 [4] Note: This step is non-optional. Failure to do this step 1984 can result in a significant reduction in the functionality of the 1985 system. Attempting to do it by hand is not recommended and those 1986 that pursue this avenue should read this file carefully, as well 1987 as the archives of freebsd-current and freebsd-hackers mailing lists 1988 for potential gotchas. The -U option is also useful to consider. 1989 See mergemaster(8) for more information. 1990 1991 [5] Usually this step is a no-op. However, from time to time 1992 you may need to do this if you get unknown user in the following 1993 step. It never hurts to do it all the time. You may need to 1994 install a new mergemaster (cd src/usr.sbin/mergemaster && make 1995 install) after the buildworld before this step if you last updated 1996 from current before 20130425 or from -stable before 20130430. 1997 1998 [6] This only deletes old files and directories. Old libraries 1999 can be deleted by "make delete-old-libs", but you have to make 2000 sure that no program is using those libraries anymore. 2001 2002 [8] The new kernel must be able to run existing binaries used by an 2003 installworld. When upgrading across major versions, the new kernel's 2004 configuration must include the correct COMPAT_FREEBSD<n> option for 2005 existing binaries (e.g. COMPAT_FREEBSD11 to run 11.x binaries). Failure 2006 to do so may leave you with a system that is hard to boot to recover. A 2007 GENERIC kernel will include suitable compatibility options to run 2008 binaries from older branches. Note that the ability to run binaries 2009 from unsupported branches is not guaranteed. 2010 2011 Make sure that you merge any new devices from GENERIC since the 2012 last time you updated your kernel config file.
