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 TO PEOPLE WHO THINK THAT FreeBSD 13.x IS SLOW: 15 FreeBSD 13.x has many debugging features turned on, in both the kernel 16 and userland. These features attempt to detect incorrect use of 17 system primitives, and encourage loud failure through extra sanity 18 checking and fail stop semantics. They also substantially impact 19 system performance. If you want to do performance measurement, 20 benchmarking, and optimization, you'll want to turn them off. This 21 includes various WITNESS- related kernel options, INVARIANTS, malloc 22 debugging flags in userland, and various verbose features in the 23 kernel. Many developers choose to disable these features on build 24 machines to maximize performance. (To completely disable malloc 25 debugging, define MALLOC_PRODUCTION in /etc/make.conf, or to merely 26 disable the most expensive debugging functionality run 27 "ln -s 'abort:false,junk:false' /etc/malloc.conf".) 28 2920191120: 30 The amd(8) automount daemon has been disabled by default, and will be 31 removed in the future. As of FreeBSD 10.1 the autofs(5) is available 32 for automounting. 33 3420191107: 35 The nctgpio and wbwd drivers have been moved to the superio bus. 36 If you have one of these drivers in a kernel configuration, then 37 you should add device superio to it. If you use one of these drivers 38 as a module and you compile a custom set of modules, then you should 39 add superio to the set. 40 4120191021: 42 KPIs for network drivers to access interface addresses have changed. 43 Users need to recompile NIC driver modules together with kernel. 44 4520191021: 46 The net.link.tap.user_open sysctl no longer prevents user opening of 47 already created /dev/tapNN devices. Access is still controlled by 48 node permissions, just like tun devices. The net.link.tap.user_open 49 sysctl is now used only to allow users to perform devfs cloning of 50 tap devices, and the subsequent open may not succeed if the user is not 51 in the appropriate group. This sysctl may be deprecated/removed 52 completely in the future. 53 5420191009: 55 mips, powerpc, and sparc64 are no longer built as part of 56 universe / tinderbox unless MAKE_OBSOLETE_GCC is defined. If 57 not defined, mips, powerpc, and sparc64 builds will look for 58 the xtoolchain binaries and if installed use them for universe 59 builds. As llvm 9.0 becomes vetted for these architectures, they 60 will be removed from the list. 61 6220191009: 63 Clang, llvm, lld, lldb, compiler-rt, libc++, libunwind and openmp have 64 been upgraded to 9.0.0. Please see the 20141231 entry below for 65 information about prerequisites and upgrading, if you are not already 66 using clang 3.5.0 or higher. 67 6820191003: 69 The hpt27xx, hptmv, hptnr, and hptrr drivers have been removed from 70 GENERIC. They are available as modules and can be loaded by adding 71 to /boot/loader.conf hpt27xx_load="YES", hptmv_load="YES", 72 hptnr_load="YES", or hptrr_load="YES", respectively. 73 7420190913: 75 ntpd no longer by default locks its pages in memory, allowing them 76 to be paged out by the kernel. Use rlimit memlock to restore 77 historic BSD behaviour. For example, add "rlimit memlock 32" 78 to ntp.conf to lock up to 32 MB of ntpd address space in memory. 79 8020190823: 81 Several of ping6's options have been renamed for better consistency 82 with ping. If you use any of -ARWXaghmrtwx, you must update your 83 scripts. See ping6(8) for details. 84 8520190727: 86 The vfs.fusefs.sync_unmount and vfs.fusefs.init_backgrounded sysctls 87 and the "-o sync_unmount" and "-o init_backgrounded" mount options have 88 been removed from mount_fusefs(8). You can safely remove them from 89 your scripts, because they had no effect. 90 91 The vfs.fusefs.fix_broken_io, vfs.fusefs.sync_resize, 92 vfs.fusefs.refresh_size, vfs.fusefs.mmap_enable, 93 vfs.fusefs.reclaim_revoked, and vfs.fusefs.data_cache_invalidate 94 sysctls have been removed. If you felt the need to set any of them to 95 a non-default value, please tell asomers@FreeBSD.org why. 96 9720190713: 98 Default permissions on the /var/account/acct file (and copies of it 99 rotated by periodic daily scripts) are changed from 0644 to 0640 100 because the file contains sensitive information that should not be 101 world-readable. If the /var/account directory must be created by 102 rc.d/accounting, the mode used is now 0750. Admins who use the 103 accounting feature are encouraged to change the mode of an existing 104 /var/account directory to 0750 or 0700. 105 10620190620: 107 Entropy collection and the /dev/random device are no longer optional 108 components. The "device random" option has been removed. 109 Implementations of distilling algorithms can still be made loadable 110 with "options RANDOM_LOADABLE" (e.g., random_fortuna.ko). 111 11220190612: 113 Clang, llvm, lld, lldb, compiler-rt, libc++, libunwind and openmp have 114 been upgraded to 8.0.1. Please see the 20141231 entry below for 115 information about prerequisites and upgrading, if you are not already 116 using clang 3.5.0 or higher. 117 11820190608: 119 A fix was applied to i386 kernel modules to avoid panics with 120 dpcpu or vnet. Users need to recompile i386 kernel modules 121 having pcpu or vnet sections or they will refuse to load. 122 12320190513: 124 User-wired pages now have their own counter, 125 vm.stats.vm.v_user_wire_count. The vm.max_wired sysctl was renamed 126 to vm.max_user_wired and changed from an unsigned int to an unsigned 127 long. bhyve VMs wired with the -S are now subject to the user 128 wiring limit; the vm.max_user_wired sysctl may need to be tuned to 129 avoid running into the limit. 130 13120190507: 132 The IPSEC option has been removed from GENERIC. Users requiring 133 ipsec(4) must now load the ipsec(4) kernel module. 134 13520190507: 136 The tap(4) driver has been folded into tun(4), and the module has been 137 renamed to tuntap. You should update any kld_list="if_tap" or 138 kld_list="if_tun" entries in /etc/rc.conf, if_tap_load="YES" or 139 if_tun_load="YES" entries in /boot/loader.conf to load the if_tuntap 140 module instead, and "device tap" or "device tun" entries in kernel 141 config files to select the tuntap device instead. 142 14320190418: 144 The following knobs have been added related to tradeoffs between 145 safe use of the random device and availability in the absence of 146 entropy: 147 148 kern.random.initial_seeding.bypass_before_seeding: tunable; set 149 non-zero to bypass the random device prior to seeding, or zero to 150 block random requests until the random device is initially seeded. 151 For now, set to 1 (unsafe) by default to restore pre-r346250 boot 152 availability properties. 153 154 kern.random.initial_seeding.read_random_bypassed_before_seeding: 155 read-only diagnostic sysctl that is set when bypass is enabled and 156 read_random(9) is bypassed, to enable programmatic handling of this 157 initial condition, if desired. 158 159 kern.random.initial_seeding.arc4random_bypassed_before_seeding: 160 Similar to the above, but for for arc4random(9) initial seeding. 161 162 kern.random.initial_seeding.disable_bypass_warnings: tunable; set 163 non-zero to disable warnings in dmesg when the same conditions are 164 met as for the diagnostic sysctls above. Defaults to zero, i.e., 165 produce warnings in dmesg when the conditions are met. 166 16720190416: 168 The loadable random module KPI has changed; the random_infra_init() 169 routine now requires a 3rd function pointer for a bool (*)(void) 170 method that returns true if the random device is seeded (and 171 therefore unblocked). 172 17320190404: 174 r345895 reverts r320698. This implies that an nfsuserd(8) daemon 175 built from head sources between r320757 (July 6, 2017) and 176 r338192 (Aug. 22, 2018) will not work unless the "-use-udpsock" 177 is added to the command line. 178 nfsuserd daemons built from head sources that are post-r338192 are 179 not affected and should continue to work. 180 18120190320: 182 The fuse(4) module has been renamed to fusefs(4) for consistency with 183 other filesystems. You should update any kld_load="fuse" entries in 184 /etc/rc.conf, fuse_load="YES" entries in /boot/loader.conf, and 185 "options FUSE" entries in kernel config files. 186 18720190304: 188 Clang, llvm, lld, lldb, compiler-rt and libc++ have been upgraded to 189 8.0.0. Please see the 20141231 entry below for information about 190 prerequisites and upgrading, if you are not already using clang 3.5.0 191 or higher. 192 19320190226: 194 geom_uzip(4) depends on the new module xz. If geom_uzip is statically 195 compiled into your custom kernel, add 'device xz' statement to the 196 kernel config. 197 19820190219: 199 drm and drm2 have been removed from the tree. Please see 200 https://wiki.freebsd.org/Graphics for the latest information on 201 migrating to the drm ports. 202 20320190131: 204 Iflib is no longer unconditionally compiled into the kernel. Drivers 205 using iflib and statically compiled into the kernel, now require 206 the 'device iflib' config option. For the same drivers loaded as 207 modules on kernels not having 'device iflib', the iflib.ko module 208 is loaded automatically. 209 21020190125: 211 The IEEE80211_AMPDU_AGE and AH_SUPPORT_AR5416 kernel configuration 212 options no longer exist since r343219 and r343427 respectively; 213 nothing uses them, so they should be just removed from custom 214 kernel config files. 215 21620181230: 217 r342635 changes the way efibootmgr(8) works by requiring users to add 218 the -b (bootnum) parameter for commands where the bootnum was previously 219 specified with each option. For example 'efibootmgr -B 0001' is now 220 'efibootmgr -B -b 0001'. 221 22220181220: 223 r342286 modifies the NFSv4 server so that it obeys vfs.nfsd.nfs_privport 224 in the same as it is applied to NFSv2 and 3. This implies that NFSv4 225 servers that have vfs.nfsd.nfs_privport set will only allow mounts 226 from clients using a reserved port#. Since both the FreeBSD and Linux 227 NFSv4 clients use reserved port#s by default, this should not affect 228 most NFSv4 mounts. 229 23020181219: 231 The XLP config has been removed. We can't support 64-bit atomics in this 232 kernel because it is running in 32-bit mode. XLP users must transition 233 to running a 64-bit kernel (XLP64 or XLPN32). 234 235 The mips GXEMUL support has been removed from FreeBSD. MALTA* + qemu is 236 the preferred emulator today and we don't need two different ones. 237 238 The old sibyte / swarm / Broadcom BCM1250 support has been 239 removed from the mips port. 240 24120181211: 242 Clang, llvm, lld, lldb, compiler-rt and libc++ have been upgraded to 243 7.0.1. Please see the 20141231 entry below for information about 244 prerequisites and upgrading, if you are not already using clang 3.5.0 245 or higher. 246 24720181211: 248 Remove the timed and netdate programs from the base tree. Setting 249 the time with these daemons has been obsolete for over a decade. 250 25120181126: 252 On amd64, arm64 and armv7 (architectures that install LLVM's ld.lld 253 linker as /usr/bin/ld) GNU ld is no longer installed as ld.bfd, as 254 it produces broken binaries when ifuncs are in use. Users needing 255 GNU ld should install the binutils port or package. 256 25720181123: 258 The BSD crtbegin and crtend code has been enabled by default. It has 259 had extensive testing on amd64, arm64, and i386. It can be disabled 260 by building a world with -DWITHOUT_BSD_CRTBEGIN. 261 26220181115: 263 The set of CTM commands (ctm, ctm_smail, ctm_rmail, ctm_dequeue) 264 has been converted to a port (misc/ctm) and will be removed from 265 FreeBSD-13. It is available as a package (ctm) for all supported 266 FreeBSD versions. 267 26820181110: 269 The default newsyslog.conf(5) file has been changed to only include 270 files in /etc/newsyslog.conf.d/ and /usr/local/etc/newsyslog.conf.d/ if 271 the filenames end in '.conf' and do not begin with a '.'. 272 273 You should check the configuration files in these two directories match 274 this naming convention. You can verify which configuration files are 275 being included using the command: 276 $ newsyslog -Nrv 277 27820181015: 279 Ports for the DRM modules have been simplified. Now, amd64 users should 280 just install the drm-kmod port. All others should install 281 drm-legacy-kmod. 282 283 Graphics hardware that's newer than about 2010 usually works with 284 drm-kmod. For hardware older than 2013, however, some users will need 285 to use drm-legacy-kmod if drm-kmod doesn't work for them. Hardware older 286 than 2008 usually only works in drm-legacy-kmod. The graphics team can 287 only commit to hardware made since 2013 due to the complexity of the 288 market and difficulty to test all the older cards effectively. If you 289 have hardware supported by drm-kmod, you are strongly encouraged to use 290 that as you will get better support. 291 292 Other than KPI chasing, drm-legacy-kmod will not be updated. As outlined 293 elsewhere, the drm and drm2 modules will be eliminated from the src base 294 soon (with a limited exception for arm). Please update to the package 295 asap and report any issues to x11@freebsd.org. 296 297 Generally, anybody using the drm*-kmod packages should add 298 WITHOUT_DRM_MODULE=t and WITHOUT_DRM2_MODULE=t to avoid nasty 299 cross-threading surprises, especially with automatic driver 300 loading from X11 startup. These will become the defaults in 13-current 301 shortly. 302 30320181012: 304 The ixlv(4) driver has been renamed to iavf(4). As a consequence, 305 custom kernel and module loading configuration files must be updated 306 accordingly. Moreover, interfaces previous presented as ixlvN to the 307 system are now exposed as iavfN and network configuration files must 308 be adjusted as necessary. 309 31020181009: 311 OpenSSL has been updated to version 1.1.1. This update included 312 additional various API changes throughout the base system. It is 313 important to rebuild third-party software after upgrading. The value 314 of __FreeBSD_version has been bumped accordingly. 315 31620181006: 317 The legacy DRM modules and drivers have now been added to the loader's 318 module blacklist, in favor of loading them with kld_list in rc.conf(5). 319 The module blacklist may be overridden with the loader.conf(5) 320 'module_blacklist' variable, but loading them via rc.conf(5) is strongly 321 encouraged. 322 32320181002: 324 The cam(4) based nda(4) driver will be used over nvd(4) by default on 325 powerpc64. You may set 'options NVME_USE_NVD=1' in your kernel conf or 326 loader tunable 'hw.nvme.use_nvd=1' if you wish to use the existing 327 driver. Make sure to edit /boot/etc/kboot.conf and fstab to use the 328 nda device name. 329 33020180913: 331 Reproducible build mode is now on by default, in preparation for 332 FreeBSD 12.0. This eliminates build metadata such as the user, 333 host, and time from the kernel (and uname), unless the working tree 334 corresponds to a modified checkout from a version control system. 335 The previous behavior can be obtained by setting the /etc/src.conf 336 knob WITHOUT_REPRODUCIBLE_BUILD. 337 33820180826: 339 The Yarrow CSPRNG has been removed from the kernel as it has not been 340 supported by its designers since at least 2003. Fortuna has been the 341 default since FreeBSD-11. 342 34320180822: 344 devctl freeze/thaw have gone into the tree, the rc scripts have been 345 updated to use them and devmatch has been changed. You should update 346 kernel, userland and rc scripts all at the same time. 347 34820180818: 349 The default interpreter has been switched from 4th to Lua. 350 LOADER_DEFAULT_INTERP, documented in build(7), will override the default 351 interpreter. If you have custom FORTH code you will need to set 352 LOADER_DEFAULT_INTERP=4th (valid values are 4th, lua or simp) in 353 src.conf for the build. This will create default hard links between 354 loader and loader_4th instead of loader and loader_lua, the new default. 355 If you are using UEFI it will create the proper hard link to loader.efi. 356 357 bhyve uses userboot.so. It remains 4th-only until some issues are solved 358 regarding coexisting with multiple versions of FreeBSD are resolved. 359 36020180815: 361 ls(1) now respects the COLORTERM environment variable used in other 362 systems and software to indicate that a colored terminal is both 363 supported and desired. If ls(1) is suddenly emitting colors, they may 364 be disabled again by either removing the unwanted COLORTERM from your 365 environment, or using `ls --color=never`. The ls(1) specific CLICOLOR 366 may not be observed in a future release. 367 36820180808: 369 The default pager for most commands has been changed to "less". To 370 restore the old behavior, set PAGER="more" and MANPAGER="more -s" in 371 your environment. 372 37320180731: 374 The jedec_ts(4) driver has been removed. A superset of its functionality 375 is available in the jedec_dimm(4) driver, and the manpage for that 376 driver includes migration instructions. If you have "device jedec_ts" 377 in your kernel configuration file, it must be removed. 378 37920180730: 380 amd64/GENERIC now has EFI runtime services, EFIRT, enabled by default. 381 This should have no effect if the kernel is booted via BIOS/legacy boot. 382 EFIRT may be disabled via a loader tunable, efi.rt.disabled, if a system 383 has a buggy firmware that prevents a successful boot due to use of 384 runtime services. 385 38620180727: 387 Atmel AT91RM9200 and AT91SAM9, Cavium CNS 11xx and XScale 388 support has been removed from the tree. These ports were 389 obsolete and/or known to be broken for many years. 390 39120180723: 392 loader.efi has been augmented to participate more fully in the 393 UEFI boot manager protocol. loader.efi will now look at the 394 BootXXXX environment variable to determine if a specific kernel 395 or root partition was specified. XXXX is derived from BootCurrent. 396 efibootmgr(8) manages these standard UEFI variables. 397 39820180720: 399 zfsloader's functionality has now been folded into loader. 400 zfsloader is no longer necessary once you've updated your 401 boot blocks. For a transition period, we will install a 402 hardlink for zfsloader to loader to allow a smooth transition 403 until the boot blocks can be updated (hard link because old 404 zfs boot blocks don't understand symlinks). 405 40620180719: 407 ARM64 now have efifb support, if you want to have serial console 408 on your arm64 board when an screen is connected and the bootloader 409 setup a frame buffer for us to use, just add : 410 boot_serial=YES 411 boot_multicons=YES 412 in /boot/loader.conf 413 For Raspberry Pi 3 (RPI) users, this is needed even if you don't have 414 an screen connected as the firmware will setup a frame buffer are that 415 u-boot will expose as an EFI frame buffer. 416 41720180719: 418 New uid:gid added, ntpd:ntpd (123:123). Be sure to run mergemaster 419 or take steps to update /etc/passwd before doing installworld on 420 existing systems. Do not skip the "mergemaster -Fp" step before 421 installworld, as described in the update procedures near the bottom 422 of this document. Also, rc.d/ntpd now starts ntpd(8) as user ntpd 423 if the new mac_ntpd(4) policy is available, unless ntpd_flags or 424 the ntp config file contain options that change file/dir locations. 425 When such options (e.g., "statsdir" or "crypto") are used, ntpd can 426 still be run as non-root by setting ntpd_user=ntpd in rc.conf, after 427 taking steps to ensure that all required files/dirs are accessible 428 by the ntpd user. 429 43020180717: 431 Big endian arm support has been removed. 432 43320180711: 434 The static environment setup in kernel configs is no longer mutually 435 exclusive with the loader(8) environment by default. In order to 436 restore the previous default behavior of disabling the loader(8) 437 environment if a static environment is present, you must specify 438 loader_env.disabled=1 in the static environment. 439 44020180705: 441 The ABI of syscalls used by management tools like sockstat and 442 netstat has been broken to allow 32-bit binaries to work on 443 64-bit kernels without modification. These programs will need 444 to match the kernel in order to function. External programs may 445 require minor modifications to accommodate a change of type in 446 structures from pointers to 64-bit virtual addresses. 447 44820180702: 449 On i386 and amd64 atomics are now inlined. Out of tree modules using 450 atomics will need to be rebuilt. 451 45220180701: 453 The '%I' format in the kern.corefile sysctl limits the number of 454 core files that a process can generate to the number stored in the 455 debug.ncores sysctl. The '%I' format is replaced by the single digit 456 index. Previously, if all indexes were taken the kernel would overwrite 457 only a core file with the highest index in a filename. 458 Currently the system will create a new core file if there is a free 459 index or if all slots are taken it will overwrite the oldest one. 460 46120180630: 462 Clang, llvm, lld, lldb, compiler-rt and libc++ have been upgraded to 463 6.0.1. Please see the 20141231 entry below for information about 464 prerequisites and upgrading, if you are not already using clang 3.5.0 465 or higher. 466 46720180628: 468 r335753 introduced a new quoting method. However, etc/devd/devmatch.conf 469 needed to be changed to work with it. This change was made with r335763 470 and requires a mergemaster / etcupdate / etc to update the installed 471 file. 472 47320180612: 474 r334930 changed the interface between the NFS modules, so they all 475 need to be rebuilt. r335018 did a __FreeBSD_version bump for this. 476 47720180530: 478 As of r334391 lld is the default amd64 system linker; it is installed 479 as /usr/bin/ld. Kernel build workarounds (see 20180510 entry) are no 480 longer necessary. 481 48220180530: 483 The kernel / userland interface for devinfo changed, so you'll 484 need a new kernel and userland as a pair for it to work (rebuilding 485 lib/libdevinfo is all that's required). devinfo and devmatch will 486 not work, but everything else will when there's a mismatch. 487 48820180523: 489 The on-disk format for hwpmc callchain records has changed to include 490 threadid corresponding to a given record. This changes the field offsets 491 and thus requires that libpmcstat be rebuilt before using a kernel 492 later than r334108. 493 49420180517: 495 The vxge(4) driver has been removed. This driver was introduced into 496 HEAD one week before the Exar left the Ethernet market and is not 497 known to be used. If you have device vxge in your kernel config file 498 it must be removed. 499 50020180510: 501 The amd64 kernel now requires a ld that supports ifunc to produce a 502 working kernel, either lld or a newer binutils. lld is built by default 503 on amd64, and the 'buildkernel' target uses it automatically. However, 504 it is not the default linker, so building the kernel the traditional 505 way requires LD=ld.lld on the command line (or LD=/usr/local/bin/ld for 506 binutils port/package). lld will soon be default, and this requirement 507 will go away. 508 509 NOTE: As of r334391 lld is the default system linker on amd64, and no 510 workaround is necessary. 511 51220180508: 513 The nxge(4) driver has been removed. This driver was for PCI-X 10g 514 cards made by s2io/Neterion. The company was acquired by Exar and 515 no longer sells or supports Ethernet products. If you have device 516 nxge in your kernel config file it must be removed. 517 51820180504: 519 The tz database (tzdb) has been updated to 2018e. This version more 520 correctly models time stamps in time zones with negative DST such as 521 Europe/Dublin (from 1971 on), Europe/Prague (1946/7), and 522 Africa/Windhoek (1994/2017). This does not affect the UT offsets, only 523 time zone abbreviations and the tm_isdst flag. 524 52520180502: 526 The ixgb(4) driver has been removed. This driver was for an early and 527 uncommon legacy PCI 10GbE for a single ASIC, Intel 82597EX. Intel 528 quickly shifted to the long lived ixgbe family. If you have device 529 ixgb in your kernel config file it must be removed. 530 53120180501: 532 The lmc(4) driver has been removed. This was a WAN interface 533 card that was already reportedly rare in 2003, and had an ambiguous 534 license. If you have device lmc in your kernel config file it must 535 be removed. 536 53720180413: 538 Support for Arcnet networks has been removed. If you have device 539 arcnet or device cm in your kernel config file they must be 540 removed. 541 54220180411: 543 Support for FDDI networks has been removed. If you have device 544 fddi or device fpa in your kernel config file they must be 545 removed. 546 54720180406: 548 In addition to supporting RFC 3164 formatted messages, the 549 syslogd(8) service is now capable of parsing RFC 5424 formatted 550 log messages. The main benefit of using RFC 5424 is that clients 551 may now send log messages with timestamps containing year numbers, 552 microseconds and time zone offsets. 553 554 Similarly, the syslog(3) C library function has been altered to 555 send RFC 5424 formatted messages to the local system logging 556 daemon. On systems using syslogd(8), this change should have no 557 negative impact, as long as syslogd(8) and the C library are 558 updated at the same time. On systems using a different system 559 logging daemon, it may be necessary to make configuration 560 adjustments, depending on the software used. 561 562 When using syslog-ng, add the 'syslog-protocol' flag to local 563 input sources to enable parsing of RFC 5424 formatted messages: 564 565 source src { 566 unix-dgram("/var/run/log" flags(syslog-protocol)); 567 } 568 569 When using rsyslog, disable the 'SysSock.UseSpecialParser' option 570 of the 'imuxsock' module to let messages be processed by the 571 regular RFC 3164/5424 parsing pipeline: 572 573 module(load="imuxsock" SysSock.UseSpecialParser="off") 574 575 Do note that these changes only affect communication between local 576 applications and syslogd(8). The format that syslogd(8) uses to 577 store messages on disk or forward messages to other systems 578 remains unchanged. syslogd(8) still uses RFC 3164 for these 579 purposes. Options to customize this behaviour will be added in the 580 future. Utilities that process log files stored in /var/log are 581 thus expected to continue to function as before. 582 583 __FreeBSD_version has been incremented to 1200061 to denote this 584 change. 585 58620180328: 587 Support for token ring networks has been removed. If you 588 have "device token" in your kernel config you should remove 589 it. No device drivers supported token ring. 590 59120180323: 592 makefs was modified to be able to tag ISO9660 El Torito boot catalog 593 entries as EFI instead of overloading the i386 tag as done previously. 594 The amd64 mkisoimages.sh script used to build amd64 ISO images for 595 release was updated to use this. This may mean that makefs must be 596 updated before "make cdrom" can be run in the release directory. This 597 should be as simple as: 598 599 $ cd $SRCDIR/usr.sbin/makefs 600 $ make depend all install 601 60220180212: 603 FreeBSD boot loader enhanced with Lua scripting. It's purely opt-in for 604 now by building WITH_LOADER_LUA and WITHOUT_FORTH in /etc/src.conf. 605 Co-existence for the transition period will come shortly. Booting is a 606 complex environment and test coverage for Lua-enabled loaders has been 607 thin, so it would be prudent to assume it might not work and make 608 provisions for backup boot methods. 609 61020180211: 611 devmatch functionality has been turned on in devd. It will automatically 612 load drivers for unattached devices. This may cause unexpected drivers 613 to be loaded. Please report any problems to current@ and 614 imp@freebsd.org. 615 61620180114: 617 Clang, llvm, lld, lldb, compiler-rt and libc++ have been upgraded to 618 6.0.0. Please see the 20141231 entry below for information about 619 prerequisites and upgrading, if you are not already using clang 3.5.0 620 or higher. 621 62220180110: 623 LLVM's lld linker is now used as the FreeBSD/amd64 bootstrap linker. 624 This means it is used to link the kernel and userland libraries and 625 executables, but is not yet installed as /usr/bin/ld by default. 626 627 To revert to ld.bfd as the bootstrap linker, in /etc/src.conf set 628 WITHOUT_LLD_BOOTSTRAP=yes 629 63020180110: 631 On i386, pmtimer has been removed. Its functionality has been folded 632 into apm. It was a no-op on ACPI in current for a while now (but was 633 still needed on i386 in FreeBSD 11 and earlier). Users may need to 634 remove it from kernel config files. 635 63620180104: 637 The use of RSS hash from the network card aka flowid has been 638 disabled by default for lagg(4) as it's currently incompatible with 639 the lacp and loadbalance protocols. 640 641 This can be re-enabled by setting the following in loader.conf: 642 net.link.lagg.default_use_flowid="1" 643 64420180102: 645 The SW_WATCHDOG option is no longer necessary to enable the 646 hardclock-based software watchdog if no hardware watchdog is 647 configured. As before, SW_WATCHDOG will cause the software 648 watchdog to be enabled even if a hardware watchdog is configured. 649 65020171215: 651 r326887 fixes the issue described in the 20171214 UPDATING entry. 652 r326888 flips the switch back to building GELI support always. 653 65420171214: 655 r362593 broke ZFS + GELI support for reasons unknown. However, 656 it also broke ZFS support generally, so GELI has been turned off 657 by default as the lesser evil in r326857. If you boot off ZFS and/or 658 GELI, it might not be a good time to update. 659 66020171125: 661 PowerPC users must update loader(8) by rebuilding world before 662 installing a new kernel, as the protocol connecting them has 663 changed. Without the update, loader metadata will not be passed 664 successfully to the kernel and users will have to enter their 665 root partition at the kernel mountroot prompt to continue booting. 666 Newer versions of loader can boot old kernels without issue. 667 66820171110: 669 The LOADER_FIREWIRE_SUPPORT build variable as been renamed to 670 WITH/OUT_LOADER_FIREWIRE. LOADER_{NO_,}GELI_SUPPORT has been renamed 671 to WITH/OUT_LOADER_GELI. 672 67320171106: 674 The naive and non-compliant support of posix_fallocate(2) in ZFS 675 has been removed as of r325320. The system call now returns EINVAL 676 when used on a ZFS file. Although the new behavior complies with the 677 standard, some consumers are not prepared to cope with it. 678 One known victim is lld prior to r325420. 679 68020171102: 681 Building in a FreeBSD src checkout will automatically create object 682 directories now rather than store files in the current directory if 683 'make obj' was not ran. Calling 'make obj' is no longer necessary. 684 This feature can be disabled by setting WITHOUT_AUTO_OBJ=yes in 685 /etc/src-env.conf (not /etc/src.conf), or passing the option in the 686 environment. 687 68820171101: 689 The default MAKEOBJDIR has changed from /usr/obj/<srcdir> for native 690 builds, and /usr/obj/<arch>/<srcdir> for cross-builds, to a unified 691 /usr/obj/<srcdir>/<arch>. This behavior can be changed to the old 692 format by setting WITHOUT_UNIFIED_OBJDIR=yes in /etc/src-env.conf, 693 the environment, or with -DWITHOUT_UNIFIED_OBJDIR when building. 694 The UNIFIED_OBJDIR option is a transitional feature that will be 695 removed for 12.0 release; please migrate to the new format for any 696 tools by looking up the OBJDIR used by 'make -V .OBJDIR' means rather 697 than hardcoding paths. 698 69920171028: 700 The native-xtools target no longer installs the files by default to the 701 OBJDIR. Use the native-xtools-install target with a DESTDIR to install 702 to ${DESTDIR}/${NXTP} where NXTP defaults to /nxb-bin. 703 70420171021: 705 As part of the boot loader infrastructure cleanup, LOADER_*_SUPPORT 706 options are changing from controlling the build if defined / undefined 707 to controlling the build with explicit 'yes' or 'no' values. They will 708 shift to WITH/WITHOUT options to match other options in the system. 709 71020171010: 711 libstand has turned into a private library for sys/boot use only. 712 It is no longer supported as a public interface outside of sys/boot. 713 71420171005: 715 The arm port has split armv6 into armv6 and armv7. armv7 is now 716 a valid TARGET_ARCH/MACHINE_ARCH setting. If you have an armv7 system 717 and are running a kernel from before r324363, you will need to add 718 MACHINE_ARCH=armv7 to 'make buildworld' to do a native build. 719 72020171003: 721 When building multiple kernels using KERNCONF, non-existent KERNCONF 722 files will produce an error and buildkernel will fail. Previously 723 missing KERNCONF files silently failed giving no indication as to 724 why, only to subsequently discover during installkernel that the 725 desired kernel was never built in the first place. 726 72720170912: 728 The default serial number format for CTL LUNs has changed. This will 729 affect users who use /dev/diskid/* device nodes, or whose FibreChannel 730 or iSCSI clients care about their LUNs' serial numbers. Users who 731 require serial number stability should hardcode serial numbers in 732 /etc/ctl.conf . 733 73420170912: 735 For 32-bit arm compiled for hard-float support, soft-floating point 736 binaries now always get their shared libraries from 737 LD_SOFT_LIBRARY_PATH (in the past, this was only used if 738 /usr/libsoft also existed). Only users with a hard-float ld.so, but 739 soft-float everything else should be affected. 740 74120170826: 742 The geli password typed at boot is now hidden. To restore the previous 743 behavior, see geli(8) for configuration options. 744 74520170825: 746 Move PMTUD blackhole counters to TCPSTATS and remove them from bare 747 sysctl values. Minor nit, but requires a rebuild of both world/kernel 748 to complete. 749 75020170814: 751 "make check" behavior (made in ^/head@r295380) has been changed to 752 execute from a limited sandbox, as opposed to executing from 753 ${TESTSDIR}. 754 755 Behavioral changes: 756 - The "beforecheck" and "aftercheck" targets are now specified. 757 - ${CHECKDIR} (added in commit noted above) has been removed. 758 - Legacy behavior can be enabled by setting 759 WITHOUT_MAKE_CHECK_USE_SANDBOX in src.conf(5) or the environment. 760 761 If the limited sandbox mode is enabled, "make check" will execute 762 "make distribution", then install, execute the tests, and clean up the 763 sandbox if successful. 764 765 The "make distribution" and "make install" targets are typically run as 766 root to set appropriate permissions and ownership at installation time. 767 The end-user should set "WITH_INSTALL_AS_USER" in src.conf(5) or the 768 environment if executing "make check" with limited sandbox mode using 769 an unprivileged user. 770 77120170808: 772 Since the switch to GPT disk labels, fsck for UFS/FFS has been 773 unable to automatically find alternate superblocks. As of r322297, 774 the information needed to find alternate superblocks has been 775 moved to the end of the area reserved for the boot block. 776 Filesystems created with a newfs of this vintage or later 777 will create the recovery information. If you have a filesystem 778 created prior to this change and wish to have a recovery block 779 created for your filesystem, you can do so by running fsck in 780 foreground mode (i.e., do not use the -p or -y options). As it 781 starts, fsck will ask ``SAVE DATA TO FIND ALTERNATE SUPERBLOCKS'' 782 to which you should answer yes. 783 78420170728: 785 As of r321665, an NFSv4 server configuration that services 786 Kerberos mounts or clients that do not support the uid/gid in 787 owner/owner_group string capability, must explicitly enable 788 the nfsuserd daemon by adding nfsuserd_enable="YES" to the 789 machine's /etc/rc.conf file. 790 79120170722: 792 Clang, llvm, lldb, compiler-rt and libc++ have been upgraded to 5.0.0. 793 Please see the 20141231 entry below for information about prerequisites 794 and upgrading, if you are not already using clang 3.5.0 or higher. 795 79620170701: 797 WITHOUT_RCMDS is now the default. Set WITH_RCMDS if you need the 798 r-commands (rlogin, rsh, etc.) to be built with the base system. 799 80020170625: 801 The FreeBSD/powerpc platform now uses a 64-bit type for time_t. This is 802 a very major ABI incompatible change, so users of FreeBSD/powerpc must 803 be careful when performing source upgrades. It is best to run 804 'make installworld' from an alternate root system, either a live 805 CD/memory stick, or a temporary root partition. Additionally, all ports 806 must be recompiled. powerpc64 is largely unaffected, except in the case 807 of 32-bit compatibility. All 32-bit binaries will be affected. 808 80920170623: 810 Forward compatibility for the "ino64" project have been committed. This 811 will allow most new binaries to run on older kernels in a limited 812 fashion. This prevents many of the common foot-shooting actions in the 813 upgrade as well as the limited ability to roll back the kernel across 814 the ino64 upgrade. Complicated use cases may not work properly, though 815 enough simpler ones work to allow recovery in most situations. 816 81720170620: 818 Switch back to the BSDL dtc (Device Tree Compiler). Set WITH_GPL_DTC 819 if you require the GPL compiler. 820 82120170618: 822 The internal ABI used for communication between the NFS kernel modules 823 was changed by r320085, so __FreeBSD_version was bumped to 824 ensure all the NFS related modules are updated together. 825 82620170617: 827 The ABI of struct event was changed by extending the data 828 member to 64bit and adding ext fields. For upgrade, same 829 precautions as for the entry 20170523 "ino64" must be 830 followed. 831 83220170531: 833 The GNU roff toolchain has been removed from base. To render manpages 834 which are not supported by mandoc(1), man(1) can fallback on GNU roff 835 from ports (and recommends to install it). 836 To render roff(7) documents, consider using GNU roff from ports or the 837 heirloom doctools roff toolchain from ports via pkg install groff or 838 via pkg install heirloom-doctools. 839 84020170524: 841 The ath(4) and ath_hal(4) modules now build piecemeal to allow for 842 smaller runtime footprint builds. This is useful for embedded systems 843 which only require one chipset support. 844 845 If you load it as a module, make sure this is in /boot/loader.conf: 846 847 if_ath_load="YES" 848 849 This will load the HAL, all chip/RF backends and if_ath_pci. 850 If you have if_ath_pci in /boot/loader.conf, ensure it is after 851 if_ath or it will not load any HAL chipset support. 852 853 If you want to selectively load things (eg on ye cheape ARM/MIPS 854 platforms where RAM is at a premium) you should: 855 856 * load ath_hal 857 * load the chip modules in question 858 * load ath_rate, ath_dfs 859 * load ath_main 860 * load if_ath_pci and/or if_ath_ahb depending upon your particular 861 bus bind type - this is where probe/attach is done. 862 863 For further comments/feedback, poke adrian@ . 864 86520170523: 866 The "ino64" 64-bit inode project has been committed, which extends 867 a number of types to 64 bits. Upgrading in place requires care and 868 adherence to the documented upgrade procedure. 869 870 If using a custom kernel configuration ensure that the 871 COMPAT_FREEBSD11 option is included (as during the upgrade the 872 system will be running the ino64 kernel with the existing world). 873 874 For the safest in-place upgrade begin by removing previous build 875 artifacts via "rm -rf /usr/obj/*". Then, carefully follow the full 876 procedure documented below under the heading "To rebuild everything and 877 install it on the current system." Specifically, a reboot is required 878 after installing the new kernel before installing world. While an 879 installworld normally works by accident from multiuser after rebooting 880 the proper kernel, there are many cases where this will fail across this 881 upgrade and installworld from single user is required. 882 88320170424: 884 The NATM framework including the en(4), fatm(4), hatm(4), and 885 patm(4) devices has been removed. Consumers should plan a 886 migration before the end-of-life date for FreeBSD 11. 887 88820170420: 889 GNU diff has been replaced by a BSD licensed diff. Some features of GNU 890 diff has not been implemented, if those are needed a newer version of 891 GNU diff is available via the diffutils package under the gdiff name. 892 89320170413: 894 As of r316810 for ipfilter, keep frags is no longer assumed when 895 keep state is specified in a rule. r316810 aligns ipfilter with 896 documentation in man pages separating keep frags from keep state. 897 This allows keep state to be specified without forcing keep frags 898 and allows keep frags to be specified independently of keep state. 899 To maintain previous behaviour, also specify keep frags with 900 keep state (as documented in ipf.conf.5). 901 90220170407: 903 arm64 builds now use the base system LLD 4.0.0 linker by default, 904 instead of requiring that the aarch64-binutils port or package be 905 installed. To continue using aarch64-binutils, set 906 CROSS_BINUTILS_PREFIX=/usr/local/aarch64-freebsd/bin . 907 90820170405: 909 The UDP optimization in entry 20160818 that added the sysctl 910 net.inet.udp.require_l2_bcast has been reverted. L2 broadcast 911 packets will no longer be treated as L3 broadcast packets. 912 91320170331: 914 Binds and sends to the loopback addresses, IPv6 and IPv4, will now 915 use any explicitly assigned loopback address available in the jail 916 instead of using the first assigned address of the jail. 917 91820170329: 919 The ctl.ko module no longer implements the iSCSI target frontend: 920 cfiscsi.ko does instead. 921 922 If building cfiscsi.ko as a kernel module, the module can be loaded 923 via one of the following methods: 924 - `cfiscsi_load="YES"` in loader.conf(5). 925 - Add `cfiscsi` to `$kld_list` in rc.conf(5). 926 - ctladm(8)/ctld(8), when compiled with iSCSI support 927 (`WITH_ISCSI=yes` in src.conf(5)) 928 929 Please see cfiscsi(4) for more details. 930 93120170316: 932 The mmcsd.ko module now additionally depends on geom_flashmap.ko. 933 Also, mmc.ko and mmcsd.ko need to be a matching pair built from the 934 same source (previously, the dependency of mmcsd.ko on mmc.ko was 935 missing, but mmcsd.ko now will refuse to load if it is incompatible 936 with mmc.ko). 937 93820170315: 939 The syntax of ipfw(8) named states was changed to avoid ambiguity. 940 If you have used named states in the firewall rules, you need to modify 941 them after installworld and before rebooting. Now named states must 942 be prefixed with colon. 943 94420170311: 945 The old drm (sys/dev/drm/) drivers for i915 and radeon have been 946 removed as the userland we provide cannot use them. The KMS version 947 (sys/dev/drm2) supports the same hardware. 948 94920170302: 950 Clang, llvm, lldb, compiler-rt and libc++ have been upgraded to 4.0.0. 951 Please see the 20141231 entry below for information about prerequisites 952 and upgrading, if you are not already using clang 3.5.0 or higher. 953 95420170221: 955 The code that provides support for ZFS .zfs/ directory functionality 956 has been reimplemented. It's not possible now to create a snapshot 957 by mkdir under .zfs/snapshot/. That should be the only user visible 958 change. 959 96020170216: 961 EISA bus support has been removed. The WITH_EISA option is no longer 962 valid. 963 96420170215: 965 MCA bus support has been removed. 966 96720170127: 968 The WITH_LLD_AS_LD / WITHOUT_LLD_AS_LD build knobs have been renamed 969 WITH_LLD_IS_LD / WITHOUT_LLD_IS_LD, for consistency with CLANG_IS_CC. 970 97120170112: 972 The EM_MULTIQUEUE kernel configuration option is deprecated now that 973 the em(4) driver conforms to iflib specifications. 974 97520170109: 976 The igb(4), em(4) and lem(4) ethernet drivers are now implemented via 977 IFLIB. If you have a custom kernel configuration that excludes em(4) 978 but you use igb(4), you need to re-add em(4) to your custom 979 configuration. 980 98120161217: 982 Clang, llvm, lldb, compiler-rt and libc++ have been upgraded to 3.9.1. 983 Please see the 20141231 entry below for information about prerequisites 984 and upgrading, if you are not already using clang 3.5.0 or higher. 985 98620161124: 987 Clang, llvm, lldb, compiler-rt and libc++ have been upgraded to 3.9.0. 988 Please see the 20141231 entry below for information about prerequisites 989 and upgrading, if you are not already using clang 3.5.0 or higher. 990 99120161119: 992 The layout of the pmap structure has changed for powerpc to put the pmap 993 statistics at the front for all CPU variations. libkvm(3) and all tools 994 that link against it need to be recompiled. 995 99620161030: 997 isl(4) and cyapa(4) drivers now require a new driver, 998 chromebook_platform(4), to work properly on Chromebook-class hardware. 999 On other types of hardware the drivers may need to be configured using 1000 device hints. Please see the corresponding manual pages for details. 1001 100220161017: 1003 The urtwn(4) driver was merged into rtwn(4) and now consists of 1004 rtwn(4) main module + rtwn_usb(4) and rtwn_pci(4) bus-specific 1005 parts. 1006 Also, firmware for RTL8188CE was renamed due to possible name 1007 conflict (rtwnrtl8192cU(B) -> rtwnrtl8192cE(B)) 1008 100920161015: 1010 GNU rcs has been removed from base. It is available as packages: 1011 - rcs: Latest GPLv3 GNU rcs version. 1012 - rcs57: Copy of the latest version of GNU rcs (GPLv2) before it was 1013 removed from base. 1014 101520161008: 1016 Use of the cc_cdg, cc_chd, cc_hd, or cc_vegas congestion control 1017 modules now requires that the kernel configuration contain the 1018 TCP_HHOOK option. (This option is included in the GENERIC kernel.) 1019 102020161003: 1021 The WITHOUT_ELFCOPY_AS_OBJCOPY src.conf(5) knob has been retired. 1022 ELF Tool Chain's elfcopy is always installed as /usr/bin/objcopy. 1023 102420160924: 1025 Relocatable object files with the extension of .So have been renamed 1026 to use an extension of .pico instead. The purpose of this change is 1027 to avoid a name clash with shared libraries on case-insensitive file 1028 systems. On those file systems, foo.So is the same file as foo.so. 1029 103020160918: 1031 GNU rcs has been turned off by default. It can (temporarily) be built 1032 again by adding WITH_RCS knob in src.conf. 1033 Otherwise, GNU rcs is available from packages: 1034 - rcs: Latest GPLv3 GNU rcs version. 1035 - rcs57: Copy of the latest version of GNU rcs (GPLv2) from base. 1036 103720160918: 1038 The backup_uses_rcs functionality has been removed from rc.subr. 1039 104020160908: 1041 The queue(3) debugging macro, QUEUE_MACRO_DEBUG, has been split into 1042 two separate components, QUEUE_MACRO_DEBUG_TRACE and 1043 QUEUE_MACRO_DEBUG_TRASH. Define both for the original 1044 QUEUE_MACRO_DEBUG behavior. 1045 104620160824: 1047 r304787 changed some ioctl interfaces between the iSCSI userspace 1048 programs and the kernel. ctladm, ctld, iscsictl, and iscsid must be 1049 rebuilt to work with new kernels. __FreeBSD_version has been bumped 1050 to 1200005. 1051 105220160818: 1053 The UDP receive code has been updated to only treat incoming UDP 1054 packets that were addressed to an L2 broadcast address as L3 1055 broadcast packets. It is not expected that this will affect any 1056 standards-conforming UDP application. The new behaviour can be 1057 disabled by setting the sysctl net.inet.udp.require_l2_bcast to 1058 0. 1059 106020160818: 1061 Remove the openbsd_poll system call. 1062 __FreeBSD_version has been bumped because of this. 1063 106420160708: 1065 The stable/11 branch has been created from head@r302406. 1066 106720160622: 1068 The libc stub for the pipe(2) system call has been replaced with 1069 a wrapper that calls the pipe2(2) system call and the pipe(2) 1070 system call is now only implemented by the kernels that include 1071 "options COMPAT_FREEBSD10" in their config file (this is the 1072 default). Users should ensure that this option is enabled in 1073 their kernel or upgrade userspace to r302092 before upgrading their 1074 kernel. 1075 107620160527: 1077 CAM will now strip leading spaces from SCSI disks' serial numbers. 1078 This will affect users who create UFS filesystems on SCSI disks using 1079 those disk's diskid device nodes. For example, if /etc/fstab 1080 previously contained a line like 1081 "/dev/diskid/DISK-%20%20%20%20%20%20%20ABCDEFG0123456", you should 1082 change it to "/dev/diskid/DISK-ABCDEFG0123456". Users of geom 1083 transforms like gmirror may also be affected. ZFS users should 1084 generally be fine. 1085 108620160523: 1087 The bitstring(3) API has been updated with new functionality and 1088 improved performance. But it is binary-incompatible with the old API. 1089 Objects built with the new headers may not be linked against objects 1090 built with the old headers. 1091 109220160520: 1093 The brk and sbrk functions have been removed from libc on arm64. 1094 Binutils from ports has been updated to not link to these 1095 functions and should be updated to the latest version before 1096 installing a new libc. 1097 109820160517: 1099 The armv6 port now defaults to hard float ABI. Limited support 1100 for running both hardfloat and soft float on the same system 1101 is available using the libraries installed with -DWITH_LIBSOFT. 1102 This has only been tested as an upgrade path for installworld 1103 and packages may fail or need manual intervention to run. New 1104 packages will be needed. 1105 1106 To update an existing self-hosted armv6hf system, you must add 1107 TARGET_ARCH=armv6 on the make command line for both the build 1108 and the install steps. 1109 111020160510: 1111 Kernel modules compiled outside of a kernel build now default to 1112 installing to /boot/modules instead of /boot/kernel. Many kernel 1113 modules built this way (such as those in ports) already overrode 1114 KMODDIR explicitly to install into /boot/modules. However, 1115 manually building and installing a module from /sys/modules will 1116 now install to /boot/modules instead of /boot/kernel. 1117 111820160414: 1119 The CAM I/O scheduler has been committed to the kernel. There should be 1120 no user visible impact. This does enable NCQ Trim on ada SSDs. While the 1121 list of known rogues that claim support for this but actually corrupt 1122 data is believed to be complete, be on the lookout for data 1123 corruption. The known rogue list is believed to be complete: 1124 1125 o Crucial MX100, M550 drives with MU01 firmware. 1126 o Micron M510 and M550 drives with MU01 firmware. 1127 o Micron M500 prior to MU07 firmware 1128 o Samsung 830, 840, and 850 all firmwares 1129 o FCCT M500 all firmwares 1130 1131 Crucial has firmware http://www.crucial.com/usa/en/support-ssd-firmware 1132 with working NCQ TRIM. For Micron branded drives, see your sales rep for 1133 updated firmware. Black listed drives will work correctly because these 1134 drives work correctly so long as no NCQ TRIMs are sent to them. Given 1135 this list is the same as found in Linux, it's believed there are no 1136 other rogues in the market place. All other models from the above 1137 vendors work. 1138 1139 To be safe, if you are at all concerned, you can quirk each of your 1140 drives to prevent NCQ from being sent by setting: 1141 kern.cam.ada.X.quirks="0x2" 1142 in loader.conf. If the drive requires the 4k sector quirk, set the 1143 quirks entry to 0x3. 1144 114520160330: 1146 The FAST_DEPEND build option has been removed and its functionality is 1147 now the one true way. The old mkdep(1) style of 'make depend' has 1148 been removed. See 20160311 for further details. 1149 115020160317: 1151 Resource range types have grown from unsigned long to uintmax_t. All 1152 drivers, and anything using libdevinfo, need to be recompiled. 1153 115420160311: 1155 WITH_FAST_DEPEND is now enabled by default for in-tree and out-of-tree 1156 builds. It no longer runs mkdep(1) during 'make depend', and the 1157 'make depend' stage can safely be skipped now as it is auto ran 1158 when building 'make all' and will generate all SRCS and DPSRCS before 1159 building anything else. Dependencies are gathered at compile time with 1160 -MF flags kept in separate .depend files per object file. Users should 1161 run 'make cleandepend' once if using -DNO_CLEAN to clean out older 1162 stale .depend files. 1163 116420160306: 1165 On amd64, clang 3.8.0 can now insert sections of type AMD64_UNWIND into 1166 kernel modules. Therefore, if you load any kernel modules at boot time, 1167 please install the boot loaders after you install the kernel, but before 1168 rebooting, e.g.: 1169 1170 make buildworld 1171 make buildkernel KERNCONF=YOUR_KERNEL_HERE 1172 make installkernel KERNCONF=YOUR_KERNEL_HERE 1173 make -C sys/boot install 1174 <reboot in single user> 1175 1176 Then follow the usual steps, described in the General Notes section, 1177 below. 1178 117920160305: 1180 Clang, llvm, lldb and compiler-rt have been upgraded to 3.8.0. Please 1181 see the 20141231 entry below for information about prerequisites and 1182 upgrading, if you are not already using clang 3.5.0 or higher. 1183 118420160301: 1185 The AIO subsystem is now a standard part of the kernel. The 1186 VFS_AIO kernel option and aio.ko kernel module have been removed. 1187 Due to stability concerns, asynchronous I/O requests are only 1188 permitted on sockets and raw disks by default. To enable 1189 asynchronous I/O requests on all file types, set the 1190 vfs.aio.enable_unsafe sysctl to a non-zero value. 1191 119220160226: 1193 The ELF object manipulation tool objcopy is now provided by the 1194 ELF Tool Chain project rather than by GNU binutils. It should be a 1195 drop-in replacement, with the addition of arm64 support. The 1196 (temporary) src.conf knob WITHOUT_ELFCOPY_AS_OBJCOPY knob may be set 1197 to obtain the GNU version if necessary. 1198 119920160129: 1200 Building ZFS pools on top of zvols is prohibited by default. That 1201 feature has never worked safely; it's always been prone to deadlocks. 1202 Using a zvol as the backing store for a VM guest's virtual disk will 1203 still work, even if the guest is using ZFS. Legacy behavior can be 1204 restored by setting vfs.zfs.vol.recursive=1. 1205 120620160119: 1207 The NONE and HPN patches has been removed from OpenSSH. They are 1208 still available in the security/openssh-portable port. 1209 121020160113: 1211 With the addition of ypldap(8), a new _ypldap user is now required 1212 during installworld. "mergemaster -p" can be used to add the user 1213 prior to installworld, as documented in the handbook. 1214 121520151216: 1216 The tftp loader (pxeboot) now uses the option root-path directive. As a 1217 consequence it no longer looks for a pxeboot.4th file on the tftp 1218 server. Instead it uses the regular /boot infrastructure as with the 1219 other loaders. 1220 122120151211: 1222 The code to start recording plug and play data into the modules has 1223 been committed. While the old tools will properly build a new kernel, 1224 a number of warnings about "unknown metadata record 4" will be produced 1225 for an older kldxref. To avoid such warnings, make sure to rebuild 1226 the kernel toolchain (or world). Make sure that you have r292078 or 1227 later when trying to build 292077 or later before rebuilding. 1228 122920151207: 1230 Debug data files are now built by default with 'make buildworld' and 1231 installed with 'make installworld'. This facilitates debugging but 1232 requires more disk space both during the build and for the installed 1233 world. Debug files may be disabled by setting WITHOUT_DEBUG_FILES=yes 1234 in src.conf(5). 1235 123620151130: 1237 r291527 changed the internal interface between the nfsd.ko and 1238 nfscommon.ko modules. As such, they must both be upgraded to-gether. 1239 __FreeBSD_version has been bumped because of this. 1240 124120151108: 1242 Add support for unicode collation strings leads to a change of 1243 order of files listed by ls(1) for example. To get back to the old 1244 behaviour, set LC_COLLATE environment variable to "C". 1245 1246 Databases administrators will need to reindex their databases given 1247 collation results will be different. 1248 1249 Due to a bug in install(1) it is recommended to remove the ancient 1250 locales before running make installworld. 1251 1252 rm -rf /usr/share/locale/* 1253 125420151030: 1255 The OpenSSL has been upgraded to 1.0.2d. Any binaries requiring 1256 libcrypto.so.7 or libssl.so.7 must be recompiled. 1257 125820151020: 1259 Qlogic 24xx/25xx firmware images were updated from 5.5.0 to 7.3.0. 1260 Kernel modules isp_2400_multi and isp_2500_multi were removed and 1261 should be replaced with isp_2400 and isp_2500 modules respectively. 1262 126320151017: 1264 The build previously allowed using 'make -n' to not recurse into 1265 sub-directories while showing what commands would be executed, and 1266 'make -n -n' to recursively show commands. Now 'make -n' will recurse 1267 and 'make -N' will not. 1268 126920151012: 1270 If you specify SENDMAIL_MC or SENDMAIL_CF in make.conf, mergemaster 1271 and etcupdate will now use this file. A custom sendmail.cf is now 1272 updated via this mechanism rather than via installworld. If you had 1273 excluded sendmail.cf in mergemaster.rc or etcupdate.conf, you may 1274 want to remove the exclusion or change it to "always install". 1275 /etc/mail/sendmail.cf is now managed the same way regardless of 1276 whether SENDMAIL_MC/SENDMAIL_CF is used. If you are not using 1277 SENDMAIL_MC/SENDMAIL_CF there should be no change in behavior. 1278 127920151011: 1280 Compatibility shims for legacy ATA device names have been removed. 1281 It includes ATA_STATIC_ID kernel option, kern.cam.ada.legacy_aliases 1282 and kern.geom.raid.legacy_aliases loader tunables, kern.devalias.* 1283 environment variables, /dev/ad* and /dev/ar* symbolic links. 1284 128520151006: 1286 Clang, llvm, lldb, compiler-rt and libc++ have been upgraded to 3.7.0. 1287 Please see the 20141231 entry below for information about prerequisites 1288 and upgrading, if you are not already using clang 3.5.0 or higher. 1289 129020150924: 1291 Kernel debug files have been moved to /usr/lib/debug/boot/kernel/, 1292 and renamed from .symbols to .debug. This reduces the size requirements 1293 on the boot partition or file system and provides consistency with 1294 userland debug files. 1295 1296 When using the supported kernel installation method the 1297 /usr/lib/debug/boot/kernel directory will be renamed (to kernel.old) 1298 as is done with /boot/kernel. 1299 1300 Developers wishing to maintain the historical behavior of installing 1301 debug files in /boot/kernel/ can set KERN_DEBUGDIR="" in src.conf(5). 1302 130320150827: 1304 The wireless drivers had undergone changes that remove the 'parent 1305 interface' from the ifconfig -l output. The rc.d network scripts 1306 used to check presence of a parent interface in the list, so old 1307 scripts would fail to start wireless networking. Thus, etcupdate(3) 1308 or mergemaster(8) run is required after kernel update, to update your 1309 rc.d scripts in /etc. 1310 131120150827: 1312 pf no longer supports 'scrub fragment crop' or 'scrub fragment drop-ovl' 1313 These configurations are now automatically interpreted as 1314 'scrub fragment reassemble'. 1315 131620150817: 1317 Kernel-loadable modules for the random(4) device are back. To use 1318 them, the kernel must have 1319 1320 device random 1321 options RANDOM_LOADABLE 1322 1323 kldload(8) can then be used to load random_fortuna.ko 1324 or random_yarrow.ko. Please note that due to the indirect 1325 function calls that the loadable modules need to provide, 1326 the build-in variants will be slightly more efficient. 1327 1328 The random(4) kernel option RANDOM_DUMMY has been retired due to 1329 unpopularity. It was not all that useful anyway. 1330 133120150813: 1332 The WITHOUT_ELFTOOLCHAIN_TOOLS src.conf(5) knob has been retired. 1333 Control over building the ELF Tool Chain tools is now provided by 1334 the WITHOUT_TOOLCHAIN knob. 1335 133620150810: 1337 The polarity of Pulse Per Second (PPS) capture events with the 1338 uart(4) driver has been corrected. Prior to this change the PPS 1339 "assert" event corresponded to the trailing edge of a positive PPS 1340 pulse and the "clear" event was the leading edge of the next pulse. 1341 1342 As the width of a PPS pulse in a typical GPS receiver is on the 1343 order of 1 millisecond, most users will not notice any significant 1344 difference with this change. 1345 1346 Anyone who has compensated for the historical polarity reversal by 1347 configuring a negative offset equal to the pulse width will need to 1348 remove that workaround. 1349 135020150809: 1351 The default group assigned to /dev/dri entries has been changed 1352 from 'wheel' to 'video' with the id of '44'. If you want to have 1353 access to the dri devices please add yourself to the video group 1354 with: 1355 1356 # pw groupmod video -m $USER 1357 135820150806: 1359 The menu.rc and loader.rc files will now be replaced during 1360 upgrades. Please migrate local changes to menu.rc.local and 1361 loader.rc.local instead. 1362 136320150805: 1364 GNU Binutils versions of addr2line, c++filt, nm, readelf, size, 1365 strings and strip have been removed. The src.conf(5) knob 1366 WITHOUT_ELFTOOLCHAIN_TOOLS no longer provides the binutils tools. 1367 136820150728: 1369 As ZFS requires more kernel stack pages than is the default on some 1370 architectures e.g. i386, it now warns if KSTACK_PAGES is less than 1371 ZFS_MIN_KSTACK_PAGES (which is 4 at the time of writing). 1372 1373 Please consider using 'options KSTACK_PAGES=X' where X is greater 1374 than or equal to ZFS_MIN_KSTACK_PAGES i.e. 4 in such configurations. 1375 137620150706: 1377 sendmail has been updated to 8.15.2. Starting with FreeBSD 11.0 1378 and sendmail 8.15, sendmail uses uncompressed IPv6 addresses by 1379 default, i.e., they will not contain "::". For example, instead 1380 of ::1, it will be 0:0:0:0:0:0:0:1. This permits a zero subnet 1381 to have a more specific match, such as different map entries for 1382 IPv6:0:0 vs IPv6:0. This change requires that configuration 1383 data (including maps, files, classes, custom ruleset, etc.) must 1384 use the same format, so make certain such configuration data is 1385 upgrading. As a very simple check search for patterns like 1386 'IPv6:[0-9a-fA-F:]*::' and 'IPv6::'. To return to the old 1387 behavior, set the m4 option confUSE_COMPRESSED_IPV6_ADDRESSES or 1388 the cf option UseCompressedIPv6Addresses. 1389 139020150630: 1391 The default kernel entropy-processing algorithm is now 1392 Fortuna, replacing Yarrow. 1393 1394 Assuming you have 'device random' in your kernel config 1395 file, the configurations allow a kernel option to override 1396 this default. You may choose *ONE* of: 1397 1398 options RANDOM_YARROW # Legacy /dev/random algorithm. 1399 options RANDOM_DUMMY # Blocking-only driver. 1400 1401 If you have neither, you get Fortuna. For most people, 1402 read no further, Fortuna will give a /dev/random that works 1403 like it always used to, and the difference will be irrelevant. 1404 1405 If you remove 'device random', you get *NO* kernel-processed 1406 entropy at all. This may be acceptable to folks building 1407 embedded systems, but has complications. Carry on reading, 1408 and it is assumed you know what you need. 1409 1410 *PLEASE* read random(4) and random(9) if you are in the 1411 habit of tweaking kernel configs, and/or if you are a member 1412 of the embedded community, wanting specific and not-usual 1413 behaviour from your security subsystems. 1414 1415 NOTE!! If you use RANDOM_DUMMY and/or have no 'device 1416 random', you will NOT have a functioning /dev/random, and 1417 many cryptographic features will not work, including SSH. 1418 You may also find strange behaviour from the random(3) set 1419 of library functions, in particular sranddev(3), srandomdev(3) 1420 and arc4random(3). The reason for this is that the KERN_ARND 1421 sysctl only returns entropy if it thinks it has some to 1422 share, and with RANDOM_DUMMY or no 'device random' this 1423 will never happen. 1424 142520150623: 1426 An additional fix for the issue described in the 20150614 sendmail 1427 entry below has been committed in revision 284717. 1428 142920150616: 1430 FreeBSD's old make (fmake) has been removed from the system. It is 1431 available as the devel/fmake port or via pkg install fmake. 1432 143320150615: 1434 The fix for the issue described in the 20150614 sendmail entry 1435 below has been committed in revision 284436. The work 1436 around described in that entry is no longer needed unless the 1437 default setting is overridden by a confDH_PARAMETERS configuration 1438 setting of '5' or pointing to a 512 bit DH parameter file. 1439 144020150614: 1441 ALLOW_DEPRECATED_ATF_TOOLS/ATFFILE support has been removed from 1442 atf.test.mk (included from bsd.test.mk). Please upgrade devel/atf 1443 and devel/kyua to version 0.20+ and adjust any calling code to work 1444 with Kyuafile and kyua. 1445 144620150614: 1447 The import of openssl to address the FreeBSD-SA-15:10.openssl 1448 security advisory includes a change which rejects handshakes 1449 with DH parameters below 768 bits. sendmail releases prior 1450 to 8.15.2 (not yet released), defaulted to a 512 bit 1451 DH parameter setting for client connections. To work around 1452 this interoperability, sendmail can be configured to use a 1453 2048 bit DH parameter by: 1454 1455 1. Edit /etc/mail/`hostname`.mc 1456 2. If a setting for confDH_PARAMETERS does not exist or 1457 exists and is set to a string beginning with '5', 1458 replace it with '2'. 1459 3. If a setting for confDH_PARAMETERS exists and is set to 1460 a file path, create a new file with: 1461 openssl dhparam -out /path/to/file 2048 1462 4. Rebuild the .cf file: 1463 cd /etc/mail/; make; make install 1464 5. Restart sendmail: 1465 cd /etc/mail/; make restart 1466 1467 A sendmail patch is coming, at which time this file will be 1468 updated. 1469 147020150604: 1471 Generation of legacy formatted entries have been disabled by default 1472 in pwd_mkdb(8), as all base system consumers of the legacy formatted 1473 entries were converted to use the new format by default when the new, 1474 machine independent format have been added and supported since FreeBSD 1475 5.x. 1476 1477 Please see the pwd_mkdb(8) manual page for further details. 1478 147920150525: 1480 Clang and llvm have been upgraded to 3.6.1 release. Please see the 1481 20141231 entry below for information about prerequisites and upgrading, 1482 if you are not already using 3.5.0 or higher. 1483 148420150521: 1485 TI platform code switched to using vendor DTS files and this update 1486 may break existing systems running on Beaglebone, Beaglebone Black, 1487 and Pandaboard: 1488 1489 - dtb files should be regenerated/reinstalled. Filenames are the 1490 same but content is different now 1491 - GPIO addressing was changed, now each GPIO bank (32 pins per bank) 1492 has its own /dev/gpiocX device, e.g. pin 121 on /dev/gpioc0 in old 1493 addressing scheme is now pin 25 on /dev/gpioc3. 1494 - Pandaboard: /etc/ttys should be updated, serial console device is 1495 now /dev/ttyu2, not /dev/ttyu0 1496 149720150501: 1498 soelim(1) from gnu/usr.bin/groff has been replaced by usr.bin/soelim. 1499 If you need the GNU extension from groff soelim(1), install groff 1500 from package: pkg install groff, or via ports: textproc/groff. 1501 150220150423: 1503 chmod, chflags, chown and chgrp now affect symlinks in -R mode as 1504 defined in symlink(7); previously symlinks were silently ignored. 1505 150620150415: 1507 The const qualifier has been removed from iconv(3) to comply with 1508 POSIX. The ports tree is aware of this from r384038 onwards. 1509 151020150416: 1511 Libraries specified by LIBADD in Makefiles must have a corresponding 1512 DPADD_<lib> variable to ensure correct dependencies. This is now 1513 enforced in src.libnames.mk. 1514 151520150324: 1516 From legacy ata(4) driver was removed support for SATA controllers 1517 supported by more functional drivers ahci(4), siis(4) and mvs(4). 1518 Kernel modules ataahci and ataadaptec were removed completely, 1519 replaced by ahci and mvs modules respectively. 1520 152120150315: 1522 Clang, llvm and lldb have been upgraded to 3.6.0 release. Please see 1523 the 20141231 entry below for information about prerequisites and 1524 upgrading, if you are not already using 3.5.0 or higher. 1525 152620150307: 1527 The 32-bit PowerPC kernel has been changed to a position-independent 1528 executable. This can only be booted with a version of loader(8) 1529 newer than January 31, 2015, so make sure to update both world and 1530 kernel before rebooting. 1531 153220150217: 1533 If you are running a -CURRENT kernel since r273872 (Oct 30th, 2014), 1534 but before r278950, the RNG was not seeded properly. Immediately 1535 upgrade the kernel to r278950 or later and regenerate any keys (e.g. 1536 ssh keys or openssl keys) that were generated w/ a kernel from that 1537 range. This does not affect programs that directly used /dev/random 1538 or /dev/urandom. All userland uses of arc4random(3) are affected. 1539 154020150210: 1541 The autofs(4) ABI was changed in order to restore binary compatibility 1542 with 10.1-RELEASE. The automountd(8) daemon needs to be rebuilt to work 1543 with the new kernel. 1544 154520150131: 1546 The powerpc64 kernel has been changed to a position-independent 1547 executable. This can only be booted with a new version of loader(8), 1548 so make sure to update both world and kernel before rebooting. 1549 155020150118: 1551 Clang and llvm have been upgraded to 3.5.1 release. This is a bugfix 1552 only release, no new features have been added. Please see the 20141231 1553 entry below for information about prerequisites and upgrading, if you 1554 are not already using 3.5.0. 1555 155620150107: 1557 ELF tools addr2line, elfcopy (strip), nm, size, and strings are now 1558 taken from the ELF Tool Chain project rather than GNU binutils. They 1559 should be drop-in replacements, with the addition of arm64 support. 1560 The WITHOUT_ELFTOOLCHAIN_TOOLS= knob may be used to obtain the 1561 binutils tools, if necessary. See 20150805 for updated information. 1562 156320150105: 1564 The default Unbound configuration now enables remote control 1565 using a local socket. Users who have already enabled the 1566 local_unbound service should regenerate their configuration 1567 by running "service local_unbound setup" as root. 1568 156920150102: 1570 The GNU texinfo and GNU info pages have been removed. 1571 To be able to view GNU info pages please install texinfo from ports. 1572 157320141231: 1574 Clang, llvm and lldb have been upgraded to 3.5.0 release. 1575 1576 As of this release, a prerequisite for building clang, llvm and lldb is 1577 a C++11 capable compiler and C++11 standard library. This means that to 1578 be able to successfully build the cross-tools stage of buildworld, with 1579 clang as the bootstrap compiler, your system compiler or cross compiler 1580 should either be clang 3.3 or later, or gcc 4.8 or later, and your 1581 system C++ library should be libc++, or libdstdc++ from gcc 4.8 or 1582 later. 1583 1584 On any standard FreeBSD 10.x or 11.x installation, where clang and 1585 libc++ are on by default (that is, on x86 or arm), this should work out 1586 of the box. 1587 1588 On 9.x installations where clang is enabled by default, e.g. on x86 and 1589 powerpc, libc++ will not be enabled by default, so libc++ should be 1590 built (with clang) and installed first. If both clang and libc++ are 1591 missing, build clang first, then use it to build libc++. 1592 1593 On 8.x and earlier installations, upgrade to 9.x first, and then follow 1594 the instructions for 9.x above. 1595 1596 Sparc64 and mips users are unaffected, as they still use gcc 4.2.1 by 1597 default, and do not build clang. 1598 1599 Many embedded systems are resource constrained, and will not be able to 1600 build clang in a reasonable time, or in some cases at all. In those 1601 cases, cross building bootable systems on amd64 is a workaround. 1602 1603 This new version of clang introduces a number of new warnings, of which 1604 the following are most likely to appear: 1605 1606 -Wabsolute-value 1607 1608 This warns in two cases, for both C and C++: 1609 * When the code is trying to take the absolute value of an unsigned 1610 quantity, which is effectively a no-op, and almost never what was 1611 intended. The code should be fixed, if at all possible. If you are 1612 sure that the unsigned quantity can be safely cast to signed, without 1613 loss of information or undefined behavior, you can add an explicit 1614 cast, or disable the warning. 1615 1616 * When the code is trying to take an absolute value, but the called 1617 abs() variant is for the wrong type, which can lead to truncation. 1618 If you want to disable the warning instead of fixing the code, please 1619 make sure that truncation will not occur, or it might lead to unwanted 1620 side-effects. 1621 1622 -Wtautological-undefined-compare and 1623 -Wundefined-bool-conversion 1624 1625 These warn when C++ code is trying to compare 'this' against NULL, while 1626 'this' should never be NULL in well-defined C++ code. However, there is 1627 some legacy (pre C++11) code out there, which actively abuses this 1628 feature, which was less strictly defined in previous C++ versions. 1629 1630 Squid and openjdk do this, for example. The warning can be turned off 1631 for C++98 and earlier, but compiling the code in C++11 mode might result 1632 in unexpected behavior; for example, the parts of the program that are 1633 unreachable could be optimized away. 1634 163520141222: 1636 The old NFS client and server (kernel options NFSCLIENT, NFSSERVER) 1637 kernel sources have been removed. The .h files remain, since some 1638 utilities include them. This will need to be fixed later. 1639 If "mount -t oldnfs ..." is attempted, it will fail. 1640 If the "-o" option on mountd(8), nfsd(8) or nfsstat(1) is used, 1641 the utilities will report errors. 1642 164320141121: 1644 The handling of LOCAL_LIB_DIRS has been altered to skip addition of 1645 directories to top level SUBDIR variable when their parent 1646 directory is included in LOCAL_DIRS. Users with build systems with 1647 such hierarchies and without SUBDIR entries in the parent 1648 directory Makefiles should add them or add the directories to 1649 LOCAL_DIRS. 1650 165120141109: 1652 faith(4) and faithd(8) have been removed from the base system. Faith 1653 has been obsolete for a very long time. 1654 165520141104: 1656 vt(4), the new console driver, is enabled by default. It brings 1657 support for Unicode and double-width characters, as well as 1658 support for UEFI and integration with the KMS kernel video 1659 drivers. 1660 1661 You may need to update your console settings in /etc/rc.conf, 1662 most probably the keymap. During boot, /etc/rc.d/syscons will 1663 indicate what you need to do. 1664 1665 vt(4) still has issues and lacks some features compared to 1666 syscons(4). See the wiki for up-to-date information: 1667 https://wiki.freebsd.org/Newcons 1668 1669 If you want to keep using syscons(4), you can do so by adding 1670 the following line to /boot/loader.conf: 1671 kern.vty=sc 1672 167320141102: 1674 pjdfstest has been integrated into kyua as an opt-in test suite. 1675 Please see share/doc/pjdfstest/README for more details on how to 1676 execute it. 1677 167820141009: 1679 gperf has been removed from the base system for architectures 1680 that use clang. Ports that require gperf will obtain it from the 1681 devel/gperf port. 1682 168320140923: 1684 pjdfstest has been moved from tools/regression/pjdfstest to 1685 contrib/pjdfstest . 1686 168720140922: 1688 At svn r271982, The default linux compat kernel ABI has been adjusted 1689 to 2.6.18 in support of the linux-c6 compat ports infrastructure 1690 update. If you wish to continue using the linux-f10 compat ports, 1691 add compat.linux.osrelease=2.6.16 to your local sysctl.conf. Users are 1692 encouraged to update their linux-compat packages to linux-c6 during 1693 their next update cycle. 1694 169520140729: 1696 The ofwfb driver, used to provide a graphics console on PowerPC when 1697 using vt(4), no longer allows mmap() of all physical memory. This 1698 will prevent Xorg on PowerPC with some ATI graphics cards from 1699 initializing properly unless x11-servers/xorg-server is updated to 1700 1.12.4_8 or newer. 1701 170220140723: 1703 The xdev targets have been converted to using TARGET and 1704 TARGET_ARCH instead of XDEV and XDEV_ARCH. 1705 170620140719: 1707 The default unbound configuration has been modified to address 1708 issues with reverse lookups on networks that use private 1709 address ranges. If you use the local_unbound service, run 1710 "service local_unbound setup" as root to regenerate your 1711 configuration, then "service local_unbound reload" to load the 1712 new configuration. 1713 171420140709: 1715 The GNU texinfo and GNU info pages are not built and installed 1716 anymore, WITH_INFO knob has been added to allow to built and install 1717 them again. 1718 UPDATE: see 20150102 entry on texinfo's removal 1719 172020140708: 1721 The GNU readline library is now an INTERNALLIB - that is, it is 1722 statically linked into consumers (GDB and variants) in the base 1723 system, and the shared library is no longer installed. The 1724 devel/readline port is available for third party software that 1725 requires readline. 1726 172720140702: 1728 The Itanium architecture (ia64) has been removed from the list of 1729 known architectures. This is the first step in the removal of the 1730 architecture. 1731 173220140701: 1733 Commit r268115 has added NFSv4.1 server support, merged from 1734 projects/nfsv4.1-server. Since this includes changes to the 1735 internal interfaces between the NFS related modules, a full 1736 build of the kernel and modules will be necessary. 1737 __FreeBSD_version has been bumped. 1738 173920140629: 1740 The WITHOUT_VT_SUPPORT kernel config knob has been renamed 1741 WITHOUT_VT. (The other _SUPPORT knobs have a consistent meaning 1742 which differs from the behaviour controlled by this knob.) 1743 174420140619: 1745 Maximal length of the serial number in CTL was increased from 16 to 1746 64 chars, that breaks ABI. All CTL-related tools, such as ctladm 1747 and ctld, need to be rebuilt to work with a new kernel. 1748 174920140606: 1750 The libatf-c and libatf-c++ major versions were downgraded to 0 and 1751 1 respectively to match the upstream numbers. They were out of 1752 sync because, when they were originally added to FreeBSD, the 1753 upstream versions were not respected. These libraries are private 1754 and not yet built by default, so renumbering them should be a 1755 non-issue. However, unclean source trees will yield broken test 1756 programs once the operator executes "make delete-old-libs" after a 1757 "make installworld". 1758 1759 Additionally, the atf-sh binary was made private by moving it into 1760 /usr/libexec/. Already-built shell test programs will keep the 1761 path to the old binary so they will break after "make delete-old" 1762 is run. 1763 1764 If you are using WITH_TESTS=yes (not the default), wipe the object 1765 tree and rebuild from scratch to prevent spurious test failures. 1766 This is only needed once: the misnumbered libraries and misplaced 1767 binaries have been added to OptionalObsoleteFiles.inc so they will 1768 be removed during a clean upgrade. 1769 177020140512: 1771 Clang and llvm have been upgraded to 3.4.1 release. 1772 177320140508: 1774 We bogusly installed src.opts.mk in /usr/share/mk. This file should 1775 be removed to avoid issues in the future (and has been added to 1776 ObsoleteFiles.inc). 1777 177820140505: 1779 /etc/src.conf now affects only builds of the FreeBSD src tree. In the 1780 past, it affected all builds that used the bsd.*.mk files. The old 1781 behavior was a bug, but people may have relied upon it. To get this 1782 behavior back, you can .include /etc/src.conf from /etc/make.conf 1783 (which is still global and isn't changed). This also changes the 1784 behavior of incremental builds inside the tree of individual 1785 directories. Set MAKESYSPATH to ".../share/mk" to do that. 1786 Although this has survived make universe and some upgrade scenarios, 1787 other upgrade scenarios may have broken. At least one form of 1788 temporary breakage was fixed with MAKESYSPATH settings for buildworld 1789 as well... In cases where MAKESYSPATH isn't working with this 1790 setting, you'll need to set it to the full path to your tree. 1791 1792 One side effect of all this cleaning up is that bsd.compiler.mk 1793 is no longer implicitly included by bsd.own.mk. If you wish to 1794 use COMPILER_TYPE, you must now explicitly include bsd.compiler.mk 1795 as well. 1796 179720140430: 1798 The lindev device has been removed since /dev/full has been made a 1799 standard device. __FreeBSD_version has been bumped. 1800 180120140424: 1802 The knob WITHOUT_VI was added to the base system, which controls 1803 building ex(1), vi(1), etc. Older releases of FreeBSD required ex(1) 1804 in order to reorder files share/termcap and didn't build ex(1) as a 1805 build tool, so building/installing with WITH_VI is highly advised for 1806 build hosts for older releases. 1807 1808 This issue has been fixed in stable/9 and stable/10 in r277022 and 1809 r276991, respectively. 1810 181120140418: 1812 The YES_HESIOD knob has been removed. It has been obsolete for 1813 a decade. Please move to using WITH_HESIOD instead or your builds 1814 will silently lack HESIOD. 1815 181620140405: 1817 The uart(4) driver has been changed with respect to its handling 1818 of the low-level console. Previously the uart(4) driver prevented 1819 any process from changing the baudrate or the CLOCAL and HUPCL 1820 control flags. By removing the restrictions, operators can make 1821 changes to the serial console port without having to reboot. 1822 However, when getty(8) is started on the serial device that is 1823 associated with the low-level console, a misconfigured terminal 1824 line in /etc/ttys will now have a real impact. 1825 Before upgrading the kernel, make sure that /etc/ttys has the 1826 serial console device configured as 3wire without baudrate to 1827 preserve the previous behaviour. E.g: 1828 ttyu0 "/usr/libexec/getty 3wire" vt100 on secure 1829 183020140306: 1831 Support for libwrap (TCP wrappers) in rpcbind was disabled by default 1832 to improve performance. To re-enable it, if needed, run rpcbind 1833 with command line option -W. 1834 183520140226: 1836 Switched back to the GPL dtc compiler due to updates in the upstream 1837 dts files not being supported by the BSDL dtc compiler. You will need 1838 to rebuild your kernel toolchain to pick up the new compiler. Core dumps 1839 may result while building dtb files during a kernel build if you fail 1840 to do so. Set WITHOUT_GPL_DTC if you require the BSDL compiler. 1841 184220140216: 1843 Clang and llvm have been upgraded to 3.4 release. 1844 184520140216: 1846 The nve(4) driver has been removed. Please use the nfe(4) driver 1847 for NVIDIA nForce MCP Ethernet adapters instead. 1848 184920140212: 1850 An ABI incompatibility crept into the libc++ 3.4 import in r261283. 1851 This could cause certain C++ applications using shared libraries built 1852 against the previous version of libc++ to crash. The incompatibility 1853 has now been fixed, but any C++ applications or shared libraries built 1854 between r261283 and r261801 should be recompiled. 1855 185620140204: 1857 OpenSSH will now ignore errors caused by kernel lacking of Capsicum 1858 capability mode support. Please note that enabling the feature in 1859 kernel is still highly recommended. 1860 186120140131: 1862 OpenSSH is now built with sandbox support, and will use sandbox as 1863 the default privilege separation method. This requires Capsicum 1864 capability mode support in kernel. 1865 186620140128: 1867 The libelf and libdwarf libraries have been updated to newer 1868 versions from upstream. Shared library version numbers for 1869 these two libraries were bumped. Any ports or binaries 1870 requiring these two libraries should be recompiled. 1871 __FreeBSD_version is bumped to 1100006. 1872 187320140110: 1874 If a Makefile in a tests/ directory was auto-generating a Kyuafile 1875 instead of providing an explicit one, this would prevent such 1876 Makefile from providing its own Kyuafile in the future during 1877 NO_CLEAN builds. This has been fixed in the Makefiles but manual 1878 intervention is needed to clean an objdir if you use NO_CLEAN: 1879 # find /usr/obj -name Kyuafile | xargs rm -f 1880 188120131213: 1882 The behavior of gss_pseudo_random() for the krb5 mechanism 1883 has changed, for applications requesting a longer random string 1884 than produced by the underlying enctype's pseudo-random() function. 1885 In particular, the random string produced from a session key of 1886 enctype aes256-cts-hmac-sha1-96 or aes256-cts-hmac-sha1-96 will 1887 be different at the 17th octet and later, after this change. 1888 The counter used in the PRF+ construction is now encoded as a 1889 big-endian integer in accordance with RFC 4402. 1890 __FreeBSD_version is bumped to 1100004. 1891 189220131108: 1893 The WITHOUT_ATF build knob has been removed and its functionality 1894 has been subsumed into the more generic WITHOUT_TESTS. If you were 1895 using the former to disable the build of the ATF libraries, you 1896 should change your settings to use the latter. 1897 189820131025: 1899 The default version of mtree is nmtree which is obtained from 1900 NetBSD. The output is generally the same, but may vary 1901 slightly. If you found you need identical output adding 1902 "-F freebsd9" to the command line should do the trick. For the 1903 time being, the old mtree is available as fmtree. 1904 190520131014: 1906 libbsdyml has been renamed to libyaml and moved to /usr/lib/private. 1907 This will break ports-mgmt/pkg. Rebuild the port, or upgrade to pkg 1908 1.1.4_8 and verify bsdyml not linked in, before running "make 1909 delete-old-libs": 1910 # make -C /usr/ports/ports-mgmt/pkg build deinstall install clean 1911 or 1912 # pkg install pkg; ldd /usr/local/sbin/pkg | grep bsdyml 1913 191420131010: 1915 The stable/10 branch has been created in subversion from head 1916 revision r256279. 1917 1918COMMON ITEMS: 1919 1920 General Notes 1921 ------------- 1922 Avoid using make -j when upgrading. While generally safe, there are 1923 sometimes problems using -j to upgrade. If your upgrade fails with 1924 -j, please try again without -j. From time to time in the past there 1925 have been problems using -j with buildworld and/or installworld. This 1926 is especially true when upgrading between "distant" versions (eg one 1927 that cross a major release boundary or several minor releases, or when 1928 several months have passed on the -current branch). 1929 1930 Sometimes, obscure build problems are the result of environment 1931 poisoning. This can happen because the make utility reads its 1932 environment when searching for values for global variables. To run 1933 your build attempts in an "environmental clean room", prefix all make 1934 commands with 'env -i '. See the env(1) manual page for more details. 1935 1936 When upgrading from one major version to another it is generally best to 1937 upgrade to the latest code in the currently installed branch first, then 1938 do an upgrade to the new branch. This is the best-tested upgrade path, 1939 and has the highest probability of being successful. Please try this 1940 approach if you encounter problems with a major version upgrade. Since 1941 the stable 4.x branch point, one has generally been able to upgrade from 1942 anywhere in the most recent stable branch to head / current (or even the 1943 last couple of stable branches). See the top of this file when there's 1944 an exception. 1945 1946 When upgrading a live system, having a root shell around before 1947 installing anything can help undo problems. Not having a root shell 1948 around can lead to problems if pam has changed too much from your 1949 starting point to allow continued authentication after the upgrade. 1950 1951 This file should be read as a log of events. When a later event changes 1952 information of a prior event, the prior event should not be deleted. 1953 Instead, a pointer to the entry with the new information should be 1954 placed in the old entry. Readers of this file should also sanity check 1955 older entries before relying on them blindly. Authors of new entries 1956 should write them with this in mind. 1957 1958 ZFS notes 1959 --------- 1960 When upgrading the boot ZFS pool to a new version, always follow 1961 these two steps: 1962 1963 1.) recompile and reinstall the ZFS boot loader and boot block 1964 (this is part of "make buildworld" and "make installworld") 1965 1966 2.) update the ZFS boot block on your boot drive 1967 1968 The following example updates the ZFS boot block on the first 1969 partition (freebsd-boot) of a GPT partitioned drive ada0: 1970 "gpart bootcode -p /boot/gptzfsboot -i 1 ada0" 1971 1972 Non-boot pools do not need these updates. 1973 1974 To build a kernel 1975 ----------------- 1976 If you are updating from a prior version of FreeBSD (even one just 1977 a few days old), you should follow this procedure. It is the most 1978 failsafe as it uses a /usr/obj tree with a fresh mini-buildworld, 1979 1980 make kernel-toolchain 1981 make -DALWAYS_CHECK_MAKE buildkernel KERNCONF=YOUR_KERNEL_HERE 1982 make -DALWAYS_CHECK_MAKE installkernel KERNCONF=YOUR_KERNEL_HERE 1983 1984 To test a kernel once 1985 --------------------- 1986 If you just want to boot a kernel once (because you are not sure 1987 if it works, or if you want to boot a known bad kernel to provide 1988 debugging information) run 1989 make installkernel KERNCONF=YOUR_KERNEL_HERE KODIR=/boot/testkernel 1990 nextboot -k testkernel 1991 1992 To rebuild everything and install it on the current system. 1993 ----------------------------------------------------------- 1994 # Note: sometimes if you are running current you gotta do more than 1995 # is listed here if you are upgrading from a really old current. 1996 1997 <make sure you have good level 0 dumps> 1998 make buildworld 1999 make buildkernel KERNCONF=YOUR_KERNEL_HERE 2000 make installkernel KERNCONF=YOUR_KERNEL_HERE 2001 [1] 2002 <reboot in single user> [3] 2003 mergemaster -Fp [5] 2004 make installworld 2005 mergemaster -Fi [4] 2006 make delete-old [6] 2007 <reboot> 2008 2009 To cross-install current onto a separate partition 2010 -------------------------------------------------- 2011 # In this approach we use a separate partition to hold 2012 # current's root, 'usr', and 'var' directories. A partition 2013 # holding "/", "/usr" and "/var" should be about 2GB in 2014 # size. 2015 2016 <make sure you have good level 0 dumps> 2017 <boot into -stable> 2018 make buildworld 2019 make buildkernel KERNCONF=YOUR_KERNEL_HERE 2020 <maybe newfs current's root partition> 2021 <mount current's root partition on directory ${CURRENT_ROOT}> 2022 make installworld DESTDIR=${CURRENT_ROOT} -DDB_FROM_SRC 2023 make distribution DESTDIR=${CURRENT_ROOT} # if newfs'd 2024 make installkernel KERNCONF=YOUR_KERNEL_HERE DESTDIR=${CURRENT_ROOT} 2025 cp /etc/fstab ${CURRENT_ROOT}/etc/fstab # if newfs'd 2026 <edit ${CURRENT_ROOT}/etc/fstab to mount "/" from the correct partition> 2027 <reboot into current> 2028 <do a "native" rebuild/install as described in the previous section> 2029 <maybe install compatibility libraries from ports/misc/compat*> 2030 <reboot> 2031 2032 2033 To upgrade in-place from stable to current 2034 ---------------------------------------------- 2035 <make sure you have good level 0 dumps> 2036 make buildworld [9] 2037 make buildkernel KERNCONF=YOUR_KERNEL_HERE [8] 2038 make installkernel KERNCONF=YOUR_KERNEL_HERE 2039 [1] 2040 <reboot in single user> [3] 2041 mergemaster -Fp [5] 2042 make installworld 2043 mergemaster -Fi [4] 2044 make delete-old [6] 2045 <reboot> 2046 2047 Make sure that you've read the UPDATING file to understand the 2048 tweaks to various things you need. At this point in the life 2049 cycle of current, things change often and you are on your own 2050 to cope. The defaults can also change, so please read ALL of 2051 the UPDATING entries. 2052 2053 Also, if you are tracking -current, you must be subscribed to 2054 freebsd-current@freebsd.org. Make sure that before you update 2055 your sources that you have read and understood all the recent 2056 messages there. If in doubt, please track -stable which has 2057 much fewer pitfalls. 2058 2059 [1] If you have third party modules, such as vmware, you 2060 should disable them at this point so they don't crash your 2061 system on reboot. 2062 2063 [3] From the bootblocks, boot -s, and then do 2064 fsck -p 2065 mount -u / 2066 mount -a 2067 sh /etc/rc.d/zfs start # mount zfs filesystem, if needed 2068 cd src # full path to source 2069 adjkerntz -i # if CMOS is wall time 2070 Also, when doing a major release upgrade, it is required that 2071 you boot into single user mode to do the installworld. 2072 2073 [4] Note: This step is non-optional. Failure to do this step 2074 can result in a significant reduction in the functionality of the 2075 system. Attempting to do it by hand is not recommended and those 2076 that pursue this avenue should read this file carefully, as well 2077 as the archives of freebsd-current and freebsd-hackers mailing lists 2078 for potential gotchas. The -U option is also useful to consider. 2079 See mergemaster(8) for more information. 2080 2081 [5] Usually this step is a no-op. However, from time to time 2082 you may need to do this if you get unknown user in the following 2083 step. It never hurts to do it all the time. You may need to 2084 install a new mergemaster (cd src/usr.sbin/mergemaster && make 2085 install) after the buildworld before this step if you last updated 2086 from current before 20130425 or from -stable before 20130430. 2087 2088 [6] This only deletes old files and directories. Old libraries 2089 can be deleted by "make delete-old-libs", but you have to make 2090 sure that no program is using those libraries anymore. 2091 2092 [8] The new kernel must be able to run existing binaries used by an 2093 installworld. When upgrading across major versions, the new kernel's 2094 configuration must include the correct COMPAT_FREEBSD<n> option for 2095 existing binaries (e.g. COMPAT_FREEBSD11 to run 11.x binaries). Failure 2096 to do so may leave you with a system that is hard to boot to recover. A 2097 GENERIC kernel will include suitable compatibility options to run 2098 binaries from older branches. Note that the ability to run binaries 2099 from unsupported branches is not guaranteed. 2100 2101 Make sure that you merge any new devices from GENERIC since the 2102 last time you updated your kernel config file. Options also 2103 change over time, so you may need to adjust your custom kernels 2104 for these as well. 2105 2106 [9] If CPUTYPE is defined in your /etc/make.conf, make sure to use the 2107 "?=" instead of the "=" assignment operator, so that buildworld can 2108 override the CPUTYPE if it needs to. 2109 2110 MAKEOBJDIRPREFIX must be defined in an environment variable, and 2111 not on the command line, or in /etc/make.conf. buildworld will 2112 warn if it is improperly defined. 2113FORMAT: 2114 2115This file contains a list, in reverse chronological order, of major 2116breakages in tracking -current. It is not guaranteed to be a complete 2117list of such breakages, and only contains entries since September 23, 2011. 2118If you need to see UPDATING entries from before that date, you will need 2119to fetch an UPDATING file from an older FreeBSD release. 2120 2121Copyright information: 2122 2123Copyright 1998-2009 M.
