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 292020mmdd: 30 Clang, llvm, lld, lldb, compiler-rt, libc++, libunwind and openmp have 31 been upgraded to 10.0.0. Please see the 20141231 entry below for 32 information about prerequisites and upgrading, if you are not already 33 using clang 3.5.0 or higher. 34 3520200220: 36 ncurses has been updated to a newer version (6.1-20200118). Given the ABI 37 has changed, users will have to rebuild all the ports that are linked to 38 ncurses. 39 4020200217: 41 The size of struct vnet and the magic cookie have changed. 42 Users need to recompile libkvm and all modules using VIMAGE 43 together with their new kernel. 44 4520200212: 46 Defining the long deprecated NO_CTF, NO_DEBUG_FILES, NO_INSTALLLIB, 47 NO_MAN, NO_PROFILE, and NO_WARNS variables is now an error. Update 48 your Makefiles and scripts to define MK_<var>=no instead as required. 49 50 One exception to this is that program or library Makefiles should 51 define MAN to empty rather than setting MK_MAN=no. 52 5320200108: 54 Clang/LLVM is now the default compiler and LLD the default 55 linker for riscv64. 56 5720200107: 58 make universe no longer uses GCC 4.2.1 on any architectures. 59 Architectures not supported by in-tree Clang/LLVM require an 60 external toolchain package. 61 6220200104: 63 GCC 4.2.1 is now not built by default, as part of the GCC 4.2.1 64 retirement plan. Specifically, the GCC, GCC_BOOTSTRAP, and GNUCXX 65 options default to off for all supported CPU architectures. As a 66 short-term transition aid they may be enabled via WITH_* options. 67 GCC 4.2.1 is expected to be removed from the tree on 2020-03-31. 68 6920200102: 70 Support for armv5 has been disconnected and is being removed. The 71 machine combination MACHINE=arm MACHINE_ARCH=arm is no longer valid. 72 You must now use a MACHINE_ARCH of armv6 or armv7. The default 73 MACHINE_ARCH for MACHINE=arm is now armv7. 74 7520191226: 76 Clang/LLVM is now the default compiler for all powerpc architectures. 77 LLD is now the default linker for powerpc64. The change for powerpc64 78 also includes a change to the ELFv2 ABI, incompatible with the existing 79 ABI. 80 8120191226: 82 Kernel-loadable random(4) modules are no longer unloadable. 83 8420191222: 85 Clang, llvm, lld, lldb, compiler-rt, libc++, libunwind and openmp have 86 been upgraded to 9.0.1. Please see the 20141231 entry below for 87 information about prerequisites and upgrading, if you are not already 88 using clang 3.5.0 or higher. 89 9020191212: 91 r355677 has modified the internal interface used between the 92 NFS modules in the kernel. As such, they must all be upgraded 93 simultaneously. I will do a version bump for this. 94 9520191205: 96 The root certificates of the Mozilla CA Certificate Store have been 97 imported into the base system and can be managed with the certctl(8) 98 utility. If you have installed the security/ca_root_nss port or package 99 with the ETCSYMLINK option (the default), be advised that there may be 100 differences between those included in the port and those included in 101 base due to differences in nss branch used as well as general update 102 frequency. Note also that certctl(8) cannot manage certs in the 103 format used by the security/ca_root_nss port. 104 10520191120: 106 The amd(8) automount daemon has been disabled by default, and will be 107 removed in the future. As of FreeBSD 10.1 the autofs(5) is available 108 for automounting. 109 11020191107: 111 The nctgpio and wbwd drivers have been moved to the superio bus. 112 If you have one of these drivers in a kernel configuration, then 113 you should add device superio to it. If you use one of these drivers 114 as a module and you compile a custom set of modules, then you should 115 add superio to the set. 116 11720191021: 118 KPIs for network drivers to access interface addresses have changed. 119 Users need to recompile NIC driver modules together with kernel. 120 12120191021: 122 The net.link.tap.user_open sysctl no longer prevents user opening of 123 already created /dev/tapNN devices. Access is still controlled by 124 node permissions, just like tun devices. The net.link.tap.user_open 125 sysctl is now used only to allow users to perform devfs cloning of 126 tap devices, and the subsequent open may not succeed if the user is not 127 in the appropriate group. This sysctl may be deprecated/removed 128 completely in the future. 129 13020191009: 131 mips, powerpc, and sparc64 are no longer built as part of 132 universe / tinderbox unless MAKE_OBSOLETE_GCC is defined. If 133 not defined, mips, powerpc, and sparc64 builds will look for 134 the xtoolchain binaries and if installed use them for universe 135 builds. As llvm 9.0 becomes vetted for these architectures, they 136 will be removed from the list. 137 13820191009: 139 Clang, llvm, lld, lldb, compiler-rt, libc++, libunwind and openmp have 140 been upgraded to 9.0.0. Please see the 20141231 entry below for 141 information about prerequisites and upgrading, if you are not already 142 using clang 3.5.0 or higher. 143 14420191003: 145 The hpt27xx, hptmv, hptnr, and hptrr drivers have been removed from 146 GENERIC. They are available as modules and can be loaded by adding 147 to /boot/loader.conf hpt27xx_load="YES", hptmv_load="YES", 148 hptnr_load="YES", or hptrr_load="YES", respectively. 149 15020190913: 151 ntpd no longer by default locks its pages in memory, allowing them 152 to be paged out by the kernel. Use rlimit memlock to restore 153 historic BSD behaviour. For example, add "rlimit memlock 32" 154 to ntp.conf to lock up to 32 MB of ntpd address space in memory. 155 15620190823: 157 Several of ping6's options have been renamed for better consistency 158 with ping. If you use any of -ARWXaghmrtwx, you must update your 159 scripts. See ping6(8) for details. 160 16120190727: 162 The vfs.fusefs.sync_unmount and vfs.fusefs.init_backgrounded sysctls 163 and the "-o sync_unmount" and "-o init_backgrounded" mount options have 164 been removed from mount_fusefs(8). You can safely remove them from 165 your scripts, because they had no effect. 166 167 The vfs.fusefs.fix_broken_io, vfs.fusefs.sync_resize, 168 vfs.fusefs.refresh_size, vfs.fusefs.mmap_enable, 169 vfs.fusefs.reclaim_revoked, and vfs.fusefs.data_cache_invalidate 170 sysctls have been removed. If you felt the need to set any of them to 171 a non-default value, please tell asomers@FreeBSD.org why. 172 17320190713: 174 Default permissions on the /var/account/acct file (and copies of it 175 rotated by periodic daily scripts) are changed from 0644 to 0640 176 because the file contains sensitive information that should not be 177 world-readable. If the /var/account directory must be created by 178 rc.d/accounting, the mode used is now 0750. Admins who use the 179 accounting feature are encouraged to change the mode of an existing 180 /var/account directory to 0750 or 0700. 181 18220190620: 183 Entropy collection and the /dev/random device are no longer optional 184 components. The "device random" option has been removed. 185 Implementations of distilling algorithms can still be made loadable 186 with "options RANDOM_LOADABLE" (e.g., random_fortuna.ko). 187 18820190612: 189 Clang, llvm, lld, lldb, compiler-rt, libc++, libunwind and openmp have 190 been upgraded to 8.0.1. Please see the 20141231 entry below for 191 information about prerequisites and upgrading, if you are not already 192 using clang 3.5.0 or higher. 193 19420190608: 195 A fix was applied to i386 kernel modules to avoid panics with 196 dpcpu or vnet. Users need to recompile i386 kernel modules 197 having pcpu or vnet sections or they will refuse to load. 198 19920190513: 200 User-wired pages now have their own counter, 201 vm.stats.vm.v_user_wire_count. The vm.max_wired sysctl was renamed 202 to vm.max_user_wired and changed from an unsigned int to an unsigned 203 long. bhyve VMs wired with the -S are now subject to the user 204 wiring limit; the vm.max_user_wired sysctl may need to be tuned to 205 avoid running into the limit. 206 20720190507: 208 The IPSEC option has been removed from GENERIC. Users requiring 209 ipsec(4) must now load the ipsec(4) kernel module. 210 21120190507: 212 The tap(4) driver has been folded into tun(4), and the module has been 213 renamed to tuntap. You should update any kld_list="if_tap" or 214 kld_list="if_tun" entries in /etc/rc.conf, if_tap_load="YES" or 215 if_tun_load="YES" entries in /boot/loader.conf to load the if_tuntap 216 module instead, and "device tap" or "device tun" entries in kernel 217 config files to select the tuntap device instead. 218 21920190418: 220 The following knobs have been added related to tradeoffs between 221 safe use of the random device and availability in the absence of 222 entropy: 223 224 kern.random.initial_seeding.bypass_before_seeding: tunable; set 225 non-zero to bypass the random device prior to seeding, or zero to 226 block random requests until the random device is initially seeded. 227 For now, set to 1 (unsafe) by default to restore pre-r346250 boot 228 availability properties. 229 230 kern.random.initial_seeding.read_random_bypassed_before_seeding: 231 read-only diagnostic sysctl that is set when bypass is enabled and 232 read_random(9) is bypassed, to enable programmatic handling of this 233 initial condition, if desired. 234 235 kern.random.initial_seeding.arc4random_bypassed_before_seeding: 236 Similar to the above, but for for arc4random(9) initial seeding. 237 238 kern.random.initial_seeding.disable_bypass_warnings: tunable; set 239 non-zero to disable warnings in dmesg when the same conditions are 240 met as for the diagnostic sysctls above. Defaults to zero, i.e., 241 produce warnings in dmesg when the conditions are met. 242 24320190416: 244 The loadable random module KPI has changed; the random_infra_init() 245 routine now requires a 3rd function pointer for a bool (*)(void) 246 method that returns true if the random device is seeded (and 247 therefore unblocked). 248 24920190404: 250 r345895 reverts r320698. This implies that an nfsuserd(8) daemon 251 built from head sources between r320757 (July 6, 2017) and 252 r338192 (Aug. 22, 2018) will not work unless the "-use-udpsock" 253 is added to the command line. 254 nfsuserd daemons built from head sources that are post-r338192 are 255 not affected and should continue to work. 256 25720190320: 258 The fuse(4) module has been renamed to fusefs(4) for consistency with 259 other filesystems. You should update any kld_load="fuse" entries in 260 /etc/rc.conf, fuse_load="YES" entries in /boot/loader.conf, and 261 "options FUSE" entries in kernel config files. 262 26320190304: 264 Clang, llvm, lld, lldb, compiler-rt and libc++ have been upgraded to 265 8.0.0. Please see the 20141231 entry below for information about 266 prerequisites and upgrading, if you are not already using clang 3.5.0 267 or higher. 268 26920190226: 270 geom_uzip(4) depends on the new module xz. If geom_uzip is statically 271 compiled into your custom kernel, add 'device xz' statement to the 272 kernel config. 273 27420190219: 275 drm and drm2 have been removed from the tree. Please see 276 https://wiki.freebsd.org/Graphics for the latest information on 277 migrating to the drm ports. 278 27920190131: 280 Iflib is no longer unconditionally compiled into the kernel. Drivers 281 using iflib and statically compiled into the kernel, now require 282 the 'device iflib' config option. For the same drivers loaded as 283 modules on kernels not having 'device iflib', the iflib.ko module 284 is loaded automatically. 285 28620190125: 287 The IEEE80211_AMPDU_AGE and AH_SUPPORT_AR5416 kernel configuration 288 options no longer exist since r343219 and r343427 respectively; 289 nothing uses them, so they should be just removed from custom 290 kernel config files. 291 29220181230: 293 r342635 changes the way efibootmgr(8) works by requiring users to add 294 the -b (bootnum) parameter for commands where the bootnum was previously 295 specified with each option. For example 'efibootmgr -B 0001' is now 296 'efibootmgr -B -b 0001'. 297 29820181220: 299 r342286 modifies the NFSv4 server so that it obeys vfs.nfsd.nfs_privport 300 in the same as it is applied to NFSv2 and 3. This implies that NFSv4 301 servers that have vfs.nfsd.nfs_privport set will only allow mounts 302 from clients using a reserved port#. Since both the FreeBSD and Linux 303 NFSv4 clients use reserved port#s by default, this should not affect 304 most NFSv4 mounts. 305 30620181219: 307 The XLP config has been removed. We can't support 64-bit atomics in this 308 kernel because it is running in 32-bit mode. XLP users must transition 309 to running a 64-bit kernel (XLP64 or XLPN32). 310 311 The mips GXEMUL support has been removed from FreeBSD. MALTA* + qemu is 312 the preferred emulator today and we don't need two different ones. 313 314 The old sibyte / swarm / Broadcom BCM1250 support has been 315 removed from the mips port. 316 31720181211: 318 Clang, llvm, lld, lldb, compiler-rt and libc++ have been upgraded to 319 7.0.1. Please see the 20141231 entry below for information about 320 prerequisites and upgrading, if you are not already using clang 3.5.0 321 or higher. 322 32320181211: 324 Remove the timed and netdate programs from the base tree. Setting 325 the time with these daemons has been obsolete for over a decade. 326 32720181126: 328 On amd64, arm64 and armv7 (architectures that install LLVM's ld.lld 329 linker as /usr/bin/ld) GNU ld is no longer installed as ld.bfd, as 330 it produces broken binaries when ifuncs are in use. Users needing 331 GNU ld should install the binutils port or package. 332 33320181123: 334 The BSD crtbegin and crtend code has been enabled by default. It has 335 had extensive testing on amd64, arm64, and i386. It can be disabled 336 by building a world with -DWITHOUT_BSD_CRTBEGIN. 337 33820181115: 339 The set of CTM commands (ctm, ctm_smail, ctm_rmail, ctm_dequeue) 340 has been converted to a port (misc/ctm) and will be removed from 341 FreeBSD-13. It is available as a package (ctm) for all supported 342 FreeBSD versions. 343 34420181110: 345 The default newsyslog.conf(5) file has been changed to only include 346 files in /etc/newsyslog.conf.d/ and /usr/local/etc/newsyslog.conf.d/ if 347 the filenames end in '.conf' and do not begin with a '.'. 348 349 You should check the configuration files in these two directories match 350 this naming convention. You can verify which configuration files are 351 being included using the command: 352 $ newsyslog -Nrv 353 35420181015: 355 Ports for the DRM modules have been simplified. Now, amd64 users should 356 just install the drm-kmod port. All others should install 357 drm-legacy-kmod. 358 359 Graphics hardware that's newer than about 2010 usually works with 360 drm-kmod. For hardware older than 2013, however, some users will need 361 to use drm-legacy-kmod if drm-kmod doesn't work for them. Hardware older 362 than 2008 usually only works in drm-legacy-kmod. The graphics team can 363 only commit to hardware made since 2013 due to the complexity of the 364 market and difficulty to test all the older cards effectively. If you 365 have hardware supported by drm-kmod, you are strongly encouraged to use 366 that as you will get better support. 367 368 Other than KPI chasing, drm-legacy-kmod will not be updated. As outlined 369 elsewhere, the drm and drm2 modules will be eliminated from the src base 370 soon (with a limited exception for arm). Please update to the package 371 asap and report any issues to x11@freebsd.org. 372 373 Generally, anybody using the drm*-kmod packages should add 374 WITHOUT_DRM_MODULE=t and WITHOUT_DRM2_MODULE=t to avoid nasty 375 cross-threading surprises, especially with automatic driver 376 loading from X11 startup. These will become the defaults in 13-current 377 shortly. 378 37920181012: 380 The ixlv(4) driver has been renamed to iavf(4). As a consequence, 381 custom kernel and module loading configuration files must be updated 382 accordingly. Moreover, interfaces previous presented as ixlvN to the 383 system are now exposed as iavfN and network configuration files must 384 be adjusted as necessary. 385 38620181009: 387 OpenSSL has been updated to version 1.1.1. This update included 388 additional various API changes throughout the base system. It is 389 important to rebuild third-party software after upgrading. The value 390 of __FreeBSD_version has been bumped accordingly. 391 39220181006: 393 The legacy DRM modules and drivers have now been added to the loader's 394 module blacklist, in favor of loading them with kld_list in rc.conf(5). 395 The module blacklist may be overridden with the loader.conf(5) 396 'module_blacklist' variable, but loading them via rc.conf(5) is strongly 397 encouraged. 398 39920181002: 400 The cam(4) based nda(4) driver will be used over nvd(4) by default on 401 powerpc64. You may set 'options NVME_USE_NVD=1' in your kernel conf or 402 loader tunable 'hw.nvme.use_nvd=1' if you wish to use the existing 403 driver. Make sure to edit /boot/etc/kboot.conf and fstab to use the 404 nda device name. 405 40620180913: 407 Reproducible build mode is now on by default, in preparation for 408 FreeBSD 12.0. This eliminates build metadata such as the user, 409 host, and time from the kernel (and uname), unless the working tree 410 corresponds to a modified checkout from a version control system. 411 The previous behavior can be obtained by setting the /etc/src.conf 412 knob WITHOUT_REPRODUCIBLE_BUILD. 413 41420180826: 415 The Yarrow CSPRNG has been removed from the kernel as it has not been 416 supported by its designers since at least 2003. Fortuna has been the 417 default since FreeBSD-11. 418 41920180822: 420 devctl freeze/thaw have gone into the tree, the rc scripts have been 421 updated to use them and devmatch has been changed. You should update 422 kernel, userland and rc scripts all at the same time. 423 42420180818: 425 The default interpreter has been switched from 4th to Lua. 426 LOADER_DEFAULT_INTERP, documented in build(7), will override the default 427 interpreter. If you have custom FORTH code you will need to set 428 LOADER_DEFAULT_INTERP=4th (valid values are 4th, lua or simp) in 429 src.conf for the build. This will create default hard links between 430 loader and loader_4th instead of loader and loader_lua, the new default. 431 If you are using UEFI it will create the proper hard link to loader.efi. 432 433 bhyve uses userboot.so. It remains 4th-only until some issues are solved 434 regarding coexisting with multiple versions of FreeBSD are resolved. 435 43620180815: 437 ls(1) now respects the COLORTERM environment variable used in other 438 systems and software to indicate that a colored terminal is both 439 supported and desired. If ls(1) is suddenly emitting colors, they may 440 be disabled again by either removing the unwanted COLORTERM from your 441 environment, or using `ls --color=never`. The ls(1) specific CLICOLOR 442 may not be observed in a future release. 443 44420180808: 445 The default pager for most commands has been changed to "less". To 446 restore the old behavior, set PAGER="more" and MANPAGER="more -s" in 447 your environment. 448 44920180731: 450 The jedec_ts(4) driver has been removed. A superset of its functionality 451 is available in the jedec_dimm(4) driver, and the manpage for that 452 driver includes migration instructions. If you have "device jedec_ts" 453 in your kernel configuration file, it must be removed. 454 45520180730: 456 amd64/GENERIC now has EFI runtime services, EFIRT, enabled by default. 457 This should have no effect if the kernel is booted via BIOS/legacy boot. 458 EFIRT may be disabled via a loader tunable, efi.rt.disabled, if a system 459 has a buggy firmware that prevents a successful boot due to use of 460 runtime services. 461 46220180727: 463 Atmel AT91RM9200 and AT91SAM9, Cavium CNS 11xx and XScale 464 support has been removed from the tree. These ports were 465 obsolete and/or known to be broken for many years. 466 46720180723: 468 loader.efi has been augmented to participate more fully in the 469 UEFI boot manager protocol. loader.efi will now look at the 470 BootXXXX environment variable to determine if a specific kernel 471 or root partition was specified. XXXX is derived from BootCurrent. 472 efibootmgr(8) manages these standard UEFI variables. 473 47420180720: 475 zfsloader's functionality has now been folded into loader. 476 zfsloader is no longer necessary once you've updated your 477 boot blocks. For a transition period, we will install a 478 hardlink for zfsloader to loader to allow a smooth transition 479 until the boot blocks can be updated (hard link because old 480 zfs boot blocks don't understand symlinks). 481 48220180719: 483 ARM64 now have efifb support, if you want to have serial console 484 on your arm64 board when an screen is connected and the bootloader 485 setup a frame buffer for us to use, just add : 486 boot_serial=YES 487 boot_multicons=YES 488 in /boot/loader.conf 489 For Raspberry Pi 3 (RPI) users, this is needed even if you don't have 490 an screen connected as the firmware will setup a frame buffer are that 491 u-boot will expose as an EFI frame buffer. 492 49320180719: 494 New uid:gid added, ntpd:ntpd (123:123). Be sure to run mergemaster 495 or take steps to update /etc/passwd before doing installworld on 496 existing systems. Do not skip the "mergemaster -Fp" step before 497 installworld, as described in the update procedures near the bottom 498 of this document. Also, rc.d/ntpd now starts ntpd(8) as user ntpd 499 if the new mac_ntpd(4) policy is available, unless ntpd_flags or 500 the ntp config file contain options that change file/dir locations. 501 When such options (e.g., "statsdir" or "crypto") are used, ntpd can 502 still be run as non-root by setting ntpd_user=ntpd in rc.conf, after 503 taking steps to ensure that all required files/dirs are accessible 504 by the ntpd user. 505 50620180717: 507 Big endian arm support has been removed. 508 50920180711: 510 The static environment setup in kernel configs is no longer mutually 511 exclusive with the loader(8) environment by default. In order to 512 restore the previous default behavior of disabling the loader(8) 513 environment if a static environment is present, you must specify 514 loader_env.disabled=1 in the static environment. 515 51620180705: 517 The ABI of syscalls used by management tools like sockstat and 518 netstat has been broken to allow 32-bit binaries to work on 519 64-bit kernels without modification. These programs will need 520 to match the kernel in order to function. External programs may 521 require minor modifications to accommodate a change of type in 522 structures from pointers to 64-bit virtual addresses. 523 52420180702: 525 On i386 and amd64 atomics are now inlined. Out of tree modules using 526 atomics will need to be rebuilt. 527 52820180701: 529 The '%I' format in the kern.corefile sysctl limits the number of 530 core files that a process can generate to the number stored in the 531 debug.ncores sysctl. The '%I' format is replaced by the single digit 532 index. Previously, if all indexes were taken the kernel would overwrite 533 only a core file with the highest index in a filename. 534 Currently the system will create a new core file if there is a free 535 index or if all slots are taken it will overwrite the oldest one. 536 53720180630: 538 Clang, llvm, lld, lldb, compiler-rt and libc++ have been upgraded to 539 6.0.1. Please see the 20141231 entry below for information about 540 prerequisites and upgrading, if you are not already using clang 3.5.0 541 or higher. 542 54320180628: 544 r335753 introduced a new quoting method. However, etc/devd/devmatch.conf 545 needed to be changed to work with it. This change was made with r335763 546 and requires a mergemaster / etcupdate / etc to update the installed 547 file. 548 54920180612: 550 r334930 changed the interface between the NFS modules, so they all 551 need to be rebuilt. r335018 did a __FreeBSD_version bump for this. 552 55320180530: 554 As of r334391 lld is the default amd64 system linker; it is installed 555 as /usr/bin/ld. Kernel build workarounds (see 20180510 entry) are no 556 longer necessary. 557 55820180530: 559 The kernel / userland interface for devinfo changed, so you'll 560 need a new kernel and userland as a pair for it to work (rebuilding 561 lib/libdevinfo is all that's required). devinfo and devmatch will 562 not work, but everything else will when there's a mismatch. 563 56420180523: 565 The on-disk format for hwpmc callchain records has changed to include 566 threadid corresponding to a given record. This changes the field offsets 567 and thus requires that libpmcstat be rebuilt before using a kernel 568 later than r334108. 569 57020180517: 571 The vxge(4) driver has been removed. This driver was introduced into 572 HEAD one week before the Exar left the Ethernet market and is not 573 known to be used. If you have device vxge in your kernel config file 574 it must be removed. 575 57620180510: 577 The amd64 kernel now requires a ld that supports ifunc to produce a 578 working kernel, either lld or a newer binutils. lld is built by default 579 on amd64, and the 'buildkernel' target uses it automatically. However, 580 it is not the default linker, so building the kernel the traditional 581 way requires LD=ld.lld on the command line (or LD=/usr/local/bin/ld for 582 binutils port/package). lld will soon be default, and this requirement 583 will go away. 584 585 NOTE: As of r334391 lld is the default system linker on amd64, and no 586 workaround is necessary. 587 58820180508: 589 The nxge(4) driver has been removed. This driver was for PCI-X 10g 590 cards made by s2io/Neterion. The company was acquired by Exar and 591 no longer sells or supports Ethernet products. If you have device 592 nxge in your kernel config file it must be removed. 593 59420180504: 595 The tz database (tzdb) has been updated to 2018e. This version more 596 correctly models time stamps in time zones with negative DST such as 597 Europe/Dublin (from 1971 on), Europe/Prague (1946/7), and 598 Africa/Windhoek (1994/2017). This does not affect the UT offsets, only 599 time zone abbreviations and the tm_isdst flag. 600 60120180502: 602 The ixgb(4) driver has been removed. This driver was for an early and 603 uncommon legacy PCI 10GbE for a single ASIC, Intel 82597EX. Intel 604 quickly shifted to the long lived ixgbe family. If you have device 605 ixgb in your kernel config file it must be removed. 606 60720180501: 608 The lmc(4) driver has been removed. This was a WAN interface 609 card that was already reportedly rare in 2003, and had an ambiguous 610 license. If you have device lmc in your kernel config file it must 611 be removed. 612 61320180413: 614 Support for Arcnet networks has been removed. If you have device 615 arcnet or device cm in your kernel config file they must be 616 removed. 617 61820180411: 619 Support for FDDI networks has been removed. If you have device 620 fddi or device fpa in your kernel config file they must be 621 removed. 622 62320180406: 624 In addition to supporting RFC 3164 formatted messages, the 625 syslogd(8) service is now capable of parsing RFC 5424 formatted 626 log messages. The main benefit of using RFC 5424 is that clients 627 may now send log messages with timestamps containing year numbers, 628 microseconds and time zone offsets. 629 630 Similarly, the syslog(3) C library function has been altered to 631 send RFC 5424 formatted messages to the local system logging 632 daemon. On systems using syslogd(8), this change should have no 633 negative impact, as long as syslogd(8) and the C library are 634 updated at the same time. On systems using a different system 635 logging daemon, it may be necessary to make configuration 636 adjustments, depending on the software used. 637 638 When using syslog-ng, add the 'syslog-protocol' flag to local 639 input sources to enable parsing of RFC 5424 formatted messages: 640 641 source src { 642 unix-dgram("/var/run/log" flags(syslog-protocol)); 643 } 644 645 When using rsyslog, disable the 'SysSock.UseSpecialParser' option 646 of the 'imuxsock' module to let messages be processed by the 647 regular RFC 3164/5424 parsing pipeline: 648 649 module(load="imuxsock" SysSock.UseSpecialParser="off") 650 651 Do note that these changes only affect communication between local 652 applications and syslogd(8). The format that syslogd(8) uses to 653 store messages on disk or forward messages to other systems 654 remains unchanged. syslogd(8) still uses RFC 3164 for these 655 purposes. Options to customize this behaviour will be added in the 656 future. Utilities that process log files stored in /var/log are 657 thus expected to continue to function as before. 658 659 __FreeBSD_version has been incremented to 1200061 to denote this 660 change. 661 66220180328: 663 Support for token ring networks has been removed. If you 664 have "device token" in your kernel config you should remove 665 it. No device drivers supported token ring. 666 66720180323: 668 makefs was modified to be able to tag ISO9660 El Torito boot catalog 669 entries as EFI instead of overloading the i386 tag as done previously. 670 The amd64 mkisoimages.sh script used to build amd64 ISO images for 671 release was updated to use this. This may mean that makefs must be 672 updated before "make cdrom" can be run in the release directory. This 673 should be as simple as: 674 675 $ cd $SRCDIR/usr.sbin/makefs 676 $ make depend all install 677 67820180212: 679 FreeBSD boot loader enhanced with Lua scripting. It's purely opt-in for 680 now by building WITH_LOADER_LUA and WITHOUT_FORTH in /etc/src.conf. 681 Co-existence for the transition period will come shortly. Booting is a 682 complex environment and test coverage for Lua-enabled loaders has been 683 thin, so it would be prudent to assume it might not work and make 684 provisions for backup boot methods. 685 68620180211: 687 devmatch functionality has been turned on in devd. It will automatically 688 load drivers for unattached devices. This may cause unexpected drivers 689 to be loaded. Please report any problems to current@ and 690 imp@freebsd.org. 691 69220180114: 693 Clang, llvm, lld, lldb, compiler-rt and libc++ have been upgraded to 694 6.0.0. Please see the 20141231 entry below for information about 695 prerequisites and upgrading, if you are not already using clang 3.5.0 696 or higher. 697 69820180110: 699 LLVM's lld linker is now used as the FreeBSD/amd64 bootstrap linker. 700 This means it is used to link the kernel and userland libraries and 701 executables, but is not yet installed as /usr/bin/ld by default. 702 703 To revert to ld.bfd as the bootstrap linker, in /etc/src.conf set 704 WITHOUT_LLD_BOOTSTRAP=yes 705 70620180110: 707 On i386, pmtimer has been removed. Its functionality has been folded 708 into apm. It was a no-op on ACPI in current for a while now (but was 709 still needed on i386 in FreeBSD 11 and earlier). Users may need to 710 remove it from kernel config files. 711 71220180104: 713 The use of RSS hash from the network card aka flowid has been 714 disabled by default for lagg(4) as it's currently incompatible with 715 the lacp and loadbalance protocols. 716 717 This can be re-enabled by setting the following in loader.conf: 718 net.link.lagg.default_use_flowid="1" 719 72020180102: 721 The SW_WATCHDOG option is no longer necessary to enable the 722 hardclock-based software watchdog if no hardware watchdog is 723 configured. As before, SW_WATCHDOG will cause the software 724 watchdog to be enabled even if a hardware watchdog is configured. 725 72620171215: 727 r326887 fixes the issue described in the 20171214 UPDATING entry. 728 r326888 flips the switch back to building GELI support always. 729 73020171214: 731 r362593 broke ZFS + GELI support for reasons unknown. However, 732 it also broke ZFS support generally, so GELI has been turned off 733 by default as the lesser evil in r326857. If you boot off ZFS and/or 734 GELI, it might not be a good time to update. 735 73620171125: 737 PowerPC users must update loader(8) by rebuilding world before 738 installing a new kernel, as the protocol connecting them has 739 changed. Without the update, loader metadata will not be passed 740 successfully to the kernel and users will have to enter their 741 root partition at the kernel mountroot prompt to continue booting. 742 Newer versions of loader can boot old kernels without issue. 743 74420171110: 745 The LOADER_FIREWIRE_SUPPORT build variable as been renamed to 746 WITH/OUT_LOADER_FIREWIRE. LOADER_{NO_,}GELI_SUPPORT has been renamed 747 to WITH/OUT_LOADER_GELI. 748 74920171106: 750 The naive and non-compliant support of posix_fallocate(2) in ZFS 751 has been removed as of r325320. The system call now returns EINVAL 752 when used on a ZFS file. Although the new behavior complies with the 753 standard, some consumers are not prepared to cope with it. 754 One known victim is lld prior to r325420. 755 75620171102: 757 Building in a FreeBSD src checkout will automatically create object 758 directories now rather than store files in the current directory if 759 'make obj' was not ran. Calling 'make obj' is no longer necessary. 760 This feature can be disabled by setting WITHOUT_AUTO_OBJ=yes in 761 /etc/src-env.conf (not /etc/src.conf), or passing the option in the 762 environment. 763 76420171101: 765 The default MAKEOBJDIR has changed from /usr/obj/<srcdir> for native 766 builds, and /usr/obj/<arch>/<srcdir> for cross-builds, to a unified 767 /usr/obj/<srcdir>/<arch>. This behavior can be changed to the old 768 format by setting WITHOUT_UNIFIED_OBJDIR=yes in /etc/src-env.conf, 769 the environment, or with -DWITHOUT_UNIFIED_OBJDIR when building. 770 The UNIFIED_OBJDIR option is a transitional feature that will be 771 removed for 12.0 release; please migrate to the new format for any 772 tools by looking up the OBJDIR used by 'make -V .OBJDIR' means rather 773 than hardcoding paths. 774 77520171028: 776 The native-xtools target no longer installs the files by default to the 777 OBJDIR. Use the native-xtools-install target with a DESTDIR to install 778 to ${DESTDIR}/${NXTP} where NXTP defaults to /nxb-bin. 779 78020171021: 781 As part of the boot loader infrastructure cleanup, LOADER_*_SUPPORT 782 options are changing from controlling the build if defined / undefined 783 to controlling the build with explicit 'yes' or 'no' values. They will 784 shift to WITH/WITHOUT options to match other options in the system. 785 78620171010: 787 libstand has turned into a private library for sys/boot use only. 788 It is no longer supported as a public interface outside of sys/boot. 789 79020171005: 791 The arm port has split armv6 into armv6 and armv7. armv7 is now 792 a valid TARGET_ARCH/MACHINE_ARCH setting. If you have an armv7 system 793 and are running a kernel from before r324363, you will need to add 794 MACHINE_ARCH=armv7 to 'make buildworld' to do a native build. 795 79620171003: 797 When building multiple kernels using KERNCONF, non-existent KERNCONF 798 files will produce an error and buildkernel will fail. Previously 799 missing KERNCONF files silently failed giving no indication as to 800 why, only to subsequently discover during installkernel that the 801 desired kernel was never built in the first place. 802 80320170912: 804 The default serial number format for CTL LUNs has changed. This will 805 affect users who use /dev/diskid/* device nodes, or whose FibreChannel 806 or iSCSI clients care about their LUNs' serial numbers. Users who 807 require serial number stability should hardcode serial numbers in 808 /etc/ctl.conf . 809 81020170912: 811 For 32-bit arm compiled for hard-float support, soft-floating point 812 binaries now always get their shared libraries from 813 LD_SOFT_LIBRARY_PATH (in the past, this was only used if 814 /usr/libsoft also existed). Only users with a hard-float ld.so, but 815 soft-float everything else should be affected. 816 81720170826: 818 The geli password typed at boot is now hidden. To restore the previous 819 behavior, see geli(8) for configuration options. 820 82120170825: 822 Move PMTUD blackhole counters to TCPSTATS and remove them from bare 823 sysctl values. Minor nit, but requires a rebuild of both world/kernel 824 to complete. 825 82620170814: 827 "make check" behavior (made in ^/head@r295380) has been changed to 828 execute from a limited sandbox, as opposed to executing from 829 ${TESTSDIR}. 830 831 Behavioral changes: 832 - The "beforecheck" and "aftercheck" targets are now specified. 833 - ${CHECKDIR} (added in commit noted above) has been removed. 834 - Legacy behavior can be enabled by setting 835 WITHOUT_MAKE_CHECK_USE_SANDBOX in src.conf(5) or the environment. 836 837 If the limited sandbox mode is enabled, "make check" will execute 838 "make distribution", then install, execute the tests, and clean up the 839 sandbox if successful. 840 841 The "make distribution" and "make install" targets are typically run as 842 root to set appropriate permissions and ownership at installation time. 843 The end-user should set "WITH_INSTALL_AS_USER" in src.conf(5) or the 844 environment if executing "make check" with limited sandbox mode using 845 an unprivileged user. 846 84720170808: 848 Since the switch to GPT disk labels, fsck for UFS/FFS has been 849 unable to automatically find alternate superblocks. As of r322297, 850 the information needed to find alternate superblocks has been 851 moved to the end of the area reserved for the boot block. 852 Filesystems created with a newfs of this vintage or later 853 will create the recovery information. If you have a filesystem 854 created prior to this change and wish to have a recovery block 855 created for your filesystem, you can do so by running fsck in 856 foreground mode (i.e., do not use the -p or -y options). As it 857 starts, fsck will ask ``SAVE DATA TO FIND ALTERNATE SUPERBLOCKS'' 858 to which you should answer yes. 859 86020170728: 861 As of r321665, an NFSv4 server configuration that services 862 Kerberos mounts or clients that do not support the uid/gid in 863 owner/owner_group string capability, must explicitly enable 864 the nfsuserd daemon by adding nfsuserd_enable="YES" to the 865 machine's /etc/rc.conf file. 866 86720170722: 868 Clang, llvm, lldb, compiler-rt and libc++ have been upgraded to 5.0.0. 869 Please see the 20141231 entry below for information about prerequisites 870 and upgrading, if you are not already using clang 3.5.0 or higher. 871 87220170701: 873 WITHOUT_RCMDS is now the default. Set WITH_RCMDS if you need the 874 r-commands (rlogin, rsh, etc.) to be built with the base system. 875 87620170625: 877 The FreeBSD/powerpc platform now uses a 64-bit type for time_t. This is 878 a very major ABI incompatible change, so users of FreeBSD/powerpc must 879 be careful when performing source upgrades. It is best to run 880 'make installworld' from an alternate root system, either a live 881 CD/memory stick, or a temporary root partition. Additionally, all ports 882 must be recompiled. powerpc64 is largely unaffected, except in the case 883 of 32-bit compatibility. All 32-bit binaries will be affected. 884 88520170623: 886 Forward compatibility for the "ino64" project have been committed. This 887 will allow most new binaries to run on older kernels in a limited 888 fashion. This prevents many of the common foot-shooting actions in the 889 upgrade as well as the limited ability to roll back the kernel across 890 the ino64 upgrade. Complicated use cases may not work properly, though 891 enough simpler ones work to allow recovery in most situations. 892 89320170620: 894 Switch back to the BSDL dtc (Device Tree Compiler). Set WITH_GPL_DTC 895 if you require the GPL compiler. 896 89720170618: 898 The internal ABI used for communication between the NFS kernel modules 899 was changed by r320085, so __FreeBSD_version was bumped to 900 ensure all the NFS related modules are updated together. 901 90220170617: 903 The ABI of struct event was changed by extending the data 904 member to 64bit and adding ext fields. For upgrade, same 905 precautions as for the entry 20170523 "ino64" must be 906 followed. 907 90820170531: 909 The GNU roff toolchain has been removed from base. To render manpages 910 which are not supported by mandoc(1), man(1) can fallback on GNU roff 911 from ports (and recommends to install it). 912 To render roff(7) documents, consider using GNU roff from ports or the 913 heirloom doctools roff toolchain from ports via pkg install groff or 914 via pkg install heirloom-doctools. 915 91620170524: 917 The ath(4) and ath_hal(4) modules now build piecemeal to allow for 918 smaller runtime footprint builds. This is useful for embedded systems 919 which only require one chipset support. 920 921 If you load it as a module, make sure this is in /boot/loader.conf: 922 923 if_ath_load="YES" 924 925 This will load the HAL, all chip/RF backends and if_ath_pci. 926 If you have if_ath_pci in /boot/loader.conf, ensure it is after 927 if_ath or it will not load any HAL chipset support. 928 929 If you want to selectively load things (eg on ye cheape ARM/MIPS 930 platforms where RAM is at a premium) you should: 931 932 * load ath_hal 933 * load the chip modules in question 934 * load ath_rate, ath_dfs 935 * load ath_main 936 * load if_ath_pci and/or if_ath_ahb depending upon your particular 937 bus bind type - this is where probe/attach is done. 938 939 For further comments/feedback, poke adrian@ . 940 94120170523: 942 The "ino64" 64-bit inode project has been committed, which extends 943 a number of types to 64 bits. Upgrading in place requires care and 944 adherence to the documented upgrade procedure. 945 946 If using a custom kernel configuration ensure that the 947 COMPAT_FREEBSD11 option is included (as during the upgrade the 948 system will be running the ino64 kernel with the existing world). 949 950 For the safest in-place upgrade begin by removing previous build 951 artifacts via "rm -rf /usr/obj/*". Then, carefully follow the full 952 procedure documented below under the heading "To rebuild everything and 953 install it on the current system." Specifically, a reboot is required 954 after installing the new kernel before installing world. While an 955 installworld normally works by accident from multiuser after rebooting 956 the proper kernel, there are many cases where this will fail across this 957 upgrade and installworld from single user is required. 958 95920170424: 960 The NATM framework including the en(4), fatm(4), hatm(4), and 961 patm(4) devices has been removed. Consumers should plan a 962 migration before the end-of-life date for FreeBSD 11. 963 96420170420: 965 GNU diff has been replaced by a BSD licensed diff. Some features of GNU 966 diff has not been implemented, if those are needed a newer version of 967 GNU diff is available via the diffutils package under the gdiff name. 968 96920170413: 970 As of r316810 for ipfilter, keep frags is no longer assumed when 971 keep state is specified in a rule. r316810 aligns ipfilter with 972 documentation in man pages separating keep frags from keep state. 973 This allows keep state to be specified without forcing keep frags 974 and allows keep frags to be specified independently of keep state. 975 To maintain previous behaviour, also specify keep frags with 976 keep state (as documented in ipf.conf.5). 977 97820170407: 979 arm64 builds now use the base system LLD 4.0.0 linker by default, 980 instead of requiring that the aarch64-binutils port or package be 981 installed. To continue using aarch64-binutils, set 982 CROSS_BINUTILS_PREFIX=/usr/local/aarch64-freebsd/bin . 983 98420170405: 985 The UDP optimization in entry 20160818 that added the sysctl 986 net.inet.udp.require_l2_bcast has been reverted. L2 broadcast 987 packets will no longer be treated as L3 broadcast packets. 988 98920170331: 990 Binds and sends to the loopback addresses, IPv6 and IPv4, will now 991 use any explicitly assigned loopback address available in the jail 992 instead of using the first assigned address of the jail. 993 99420170329: 995 The ctl.ko module no longer implements the iSCSI target frontend: 996 cfiscsi.ko does instead. 997 998 If building cfiscsi.ko as a kernel module, the module can be loaded 999 via one of the following methods: 1000 - `cfiscsi_load="YES"` in loader.conf(5). 1001 - Add `cfiscsi` to `$kld_list` in rc.conf(5). 1002 - ctladm(8)/ctld(8), when compiled with iSCSI support 1003 (`WITH_ISCSI=yes` in src.conf(5)) 1004 1005 Please see cfiscsi(4) for more details. 1006 100720170316: 1008 The mmcsd.ko module now additionally depends on geom_flashmap.ko. 1009 Also, mmc.ko and mmcsd.ko need to be a matching pair built from the 1010 same source (previously, the dependency of mmcsd.ko on mmc.ko was 1011 missing, but mmcsd.ko now will refuse to load if it is incompatible 1012 with mmc.ko). 1013 101420170315: 1015 The syntax of ipfw(8) named states was changed to avoid ambiguity. 1016 If you have used named states in the firewall rules, you need to modify 1017 them after installworld and before rebooting. Now named states must 1018 be prefixed with colon. 1019 102020170311: 1021 The old drm (sys/dev/drm/) drivers for i915 and radeon have been 1022 removed as the userland we provide cannot use them. The KMS version 1023 (sys/dev/drm2) supports the same hardware. 1024 102520170302: 1026 Clang, llvm, lldb, compiler-rt and libc++ have been upgraded to 4.0.0. 1027 Please see the 20141231 entry below for information about prerequisites 1028 and upgrading, if you are not already using clang 3.5.0 or higher. 1029 103020170221: 1031 The code that provides support for ZFS .zfs/ directory functionality 1032 has been reimplemented. It's not possible now to create a snapshot 1033 by mkdir under .zfs/snapshot/. That should be the only user visible 1034 change. 1035 103620170216: 1037 EISA bus support has been removed. The WITH_EISA option is no longer 1038 valid. 1039 104020170215: 1041 MCA bus support has been removed. 1042 104320170127: 1044 The WITH_LLD_AS_LD / WITHOUT_LLD_AS_LD build knobs have been renamed 1045 WITH_LLD_IS_LD / WITHOUT_LLD_IS_LD, for consistency with CLANG_IS_CC. 1046 104720170112: 1048 The EM_MULTIQUEUE kernel configuration option is deprecated now that 1049 the em(4) driver conforms to iflib specifications. 1050 105120170109: 1052 The igb(4), em(4) and lem(4) ethernet drivers are now implemented via 1053 IFLIB. If you have a custom kernel configuration that excludes em(4) 1054 but you use igb(4), you need to re-add em(4) to your custom 1055 configuration. 1056 105720161217: 1058 Clang, llvm, lldb, compiler-rt and libc++ have been upgraded to 3.9.1. 1059 Please see the 20141231 entry below for information about prerequisites 1060 and upgrading, if you are not already using clang 3.5.0 or higher. 1061 106220161124: 1063 Clang, llvm, lldb, compiler-rt and libc++ have been upgraded to 3.9.0. 1064 Please see the 20141231 entry below for information about prerequisites 1065 and upgrading, if you are not already using clang 3.5.0 or higher. 1066 106720161119: 1068 The layout of the pmap structure has changed for powerpc to put the pmap 1069 statistics at the front for all CPU variations. libkvm(3) and all tools 1070 that link against it need to be recompiled. 1071 107220161030: 1073 isl(4) and cyapa(4) drivers now require a new driver, 1074 chromebook_platform(4), to work properly on Chromebook-class hardware. 1075 On other types of hardware the drivers may need to be configured using 1076 device hints. Please see the corresponding manual pages for details. 1077 107820161017: 1079 The urtwn(4) driver was merged into rtwn(4) and now consists of 1080 rtwn(4) main module + rtwn_usb(4) and rtwn_pci(4) bus-specific 1081 parts. 1082 Also, firmware for RTL8188CE was renamed due to possible name 1083 conflict (rtwnrtl8192cU(B) -> rtwnrtl8192cE(B)) 1084 108520161015: 1086 GNU rcs has been removed from base. It is available as packages: 1087 - rcs: Latest GPLv3 GNU rcs version. 1088 - rcs57: Copy of the latest version of GNU rcs (GPLv2) before it was 1089 removed from base. 1090 109120161008: 1092 Use of the cc_cdg, cc_chd, cc_hd, or cc_vegas congestion control 1093 modules now requires that the kernel configuration contain the 1094 TCP_HHOOK option. (This option is included in the GENERIC kernel.) 1095 109620161003: 1097 The WITHOUT_ELFCOPY_AS_OBJCOPY src.conf(5) knob has been retired. 1098 ELF Tool Chain's elfcopy is always installed as /usr/bin/objcopy. 1099 110020160924: 1101 Relocatable object files with the extension of .So have been renamed 1102 to use an extension of .pico instead. The purpose of this change is 1103 to avoid a name clash with shared libraries on case-insensitive file 1104 systems. On those file systems, foo.So is the same file as foo.so. 1105 110620160918: 1107 GNU rcs has been turned off by default. It can (temporarily) be built 1108 again by adding WITH_RCS knob in src.conf. 1109 Otherwise, GNU rcs is available from packages: 1110 - rcs: Latest GPLv3 GNU rcs version. 1111 - rcs57: Copy of the latest version of GNU rcs (GPLv2) from base. 1112 111320160918: 1114 The backup_uses_rcs functionality has been removed from rc.subr. 1115 111620160908: 1117 The queue(3) debugging macro, QUEUE_MACRO_DEBUG, has been split into 1118 two separate components, QUEUE_MACRO_DEBUG_TRACE and 1119 QUEUE_MACRO_DEBUG_TRASH. Define both for the original 1120 QUEUE_MACRO_DEBUG behavior. 1121 112220160824: 1123 r304787 changed some ioctl interfaces between the iSCSI userspace 1124 programs and the kernel. ctladm, ctld, iscsictl, and iscsid must be 1125 rebuilt to work with new kernels. __FreeBSD_version has been bumped 1126 to 1200005. 1127 112820160818: 1129 The UDP receive code has been updated to only treat incoming UDP 1130 packets that were addressed to an L2 broadcast address as L3 1131 broadcast packets. It is not expected that this will affect any 1132 standards-conforming UDP application. The new behaviour can be 1133 disabled by setting the sysctl net.inet.udp.require_l2_bcast to 1134 0. 1135 113620160818: 1137 Remove the openbsd_poll system call. 1138 __FreeBSD_version has been bumped because of this. 1139 114020160708: 1141 The stable/11 branch has been created from head@r302406. 1142 114320160622: 1144 The libc stub for the pipe(2) system call has been replaced with 1145 a wrapper that calls the pipe2(2) system call and the pipe(2) 1146 system call is now only implemented by the kernels that include 1147 "options COMPAT_FREEBSD10" in their config file (this is the 1148 default). Users should ensure that this option is enabled in 1149 their kernel or upgrade userspace to r302092 before upgrading their 1150 kernel. 1151 115220160527: 1153 CAM will now strip leading spaces from SCSI disks' serial numbers. 1154 This will affect users who create UFS filesystems on SCSI disks using 1155 those disk's diskid device nodes. For example, if /etc/fstab 1156 previously contained a line like 1157 "/dev/diskid/DISK-%20%20%20%20%20%20%20ABCDEFG0123456", you should 1158 change it to "/dev/diskid/DISK-ABCDEFG0123456". Users of geom 1159 transforms like gmirror may also be affected. ZFS users should 1160 generally be fine. 1161 116220160523: 1163 The bitstring(3) API has been updated with new functionality and 1164 improved performance. But it is binary-incompatible with the old API. 1165 Objects built with the new headers may not be linked against objects 1166 built with the old headers. 1167 116820160520: 1169 The brk and sbrk functions have been removed from libc on arm64. 1170 Binutils from ports has been updated to not link to these 1171 functions and should be updated to the latest version before 1172 installing a new libc. 1173 117420160517: 1175 The armv6 port now defaults to hard float ABI. Limited support 1176 for running both hardfloat and soft float on the same system 1177 is available using the libraries installed with -DWITH_LIBSOFT. 1178 This has only been tested as an upgrade path for installworld 1179 and packages may fail or need manual intervention to run. New 1180 packages will be needed. 1181 1182 To update an existing self-hosted armv6hf system, you must add 1183 TARGET_ARCH=armv6 on the make command line for both the build 1184 and the install steps. 1185 118620160510: 1187 Kernel modules compiled outside of a kernel build now default to 1188 installing to /boot/modules instead of /boot/kernel. Many kernel 1189 modules built this way (such as those in ports) already overrode 1190 KMODDIR explicitly to install into /boot/modules. However, 1191 manually building and installing a module from /sys/modules will 1192 now install to /boot/modules instead of /boot/kernel. 1193 119420160414: 1195 The CAM I/O scheduler has been committed to the kernel. There should be 1196 no user visible impact. This does enable NCQ Trim on ada SSDs. While the 1197 list of known rogues that claim support for this but actually corrupt 1198 data is believed to be complete, be on the lookout for data 1199 corruption. The known rogue list is believed to be complete: 1200 1201 o Crucial MX100, M550 drives with MU01 firmware. 1202 o Micron M510 and M550 drives with MU01 firmware. 1203 o Micron M500 prior to MU07 firmware 1204 o Samsung 830, 840, and 850 all firmwares 1205 o FCCT M500 all firmwares 1206 1207 Crucial has firmware http://www.crucial.com/usa/en/support-ssd-firmware 1208 with working NCQ TRIM. For Micron branded drives, see your sales rep for 1209 updated firmware. Black listed drives will work correctly because these 1210 drives work correctly so long as no NCQ TRIMs are sent to them. Given 1211 this list is the same as found in Linux, it's believed there are no 1212 other rogues in the market place. All other models from the above 1213 vendors work. 1214 1215 To be safe, if you are at all concerned, you can quirk each of your 1216 drives to prevent NCQ from being sent by setting: 1217 kern.cam.ada.X.quirks="0x2" 1218 in loader.conf. If the drive requires the 4k sector quirk, set the 1219 quirks entry to 0x3. 1220 122120160330: 1222 The FAST_DEPEND build option has been removed and its functionality is 1223 now the one true way. The old mkdep(1) style of 'make depend' has 1224 been removed. See 20160311 for further details. 1225 122620160317: 1227 Resource range types have grown from unsigned long to uintmax_t. All 1228 drivers, and anything using libdevinfo, need to be recompiled. 1229 123020160311: 1231 WITH_FAST_DEPEND is now enabled by default for in-tree and out-of-tree 1232 builds. It no longer runs mkdep(1) during 'make depend', and the 1233 'make depend' stage can safely be skipped now as it is auto ran 1234 when building 'make all' and will generate all SRCS and DPSRCS before 1235 building anything else. Dependencies are gathered at compile time with 1236 -MF flags kept in separate .depend files per object file. Users should 1237 run 'make cleandepend' once if using -DNO_CLEAN to clean out older 1238 stale .depend files. 1239 124020160306: 1241 On amd64, clang 3.8.0 can now insert sections of type AMD64_UNWIND into 1242 kernel modules. Therefore, if you load any kernel modules at boot time, 1243 please install the boot loaders after you install the kernel, but before 1244 rebooting, e.g.: 1245 1246 make buildworld 1247 make buildkernel KERNCONF=YOUR_KERNEL_HERE 1248 make installkernel KERNCONF=YOUR_KERNEL_HERE 1249 make -C sys/boot install 1250 <reboot in single user> 1251 1252 Then follow the usual steps, described in the General Notes section, 1253 below. 1254 125520160305: 1256 Clang, llvm, lldb and compiler-rt have been upgraded to 3.8.0. Please 1257 see the 20141231 entry below for information about prerequisites and 1258 upgrading, if you are not already using clang 3.5.0 or higher. 1259 126020160301: 1261 The AIO subsystem is now a standard part of the kernel. The 1262 VFS_AIO kernel option and aio.ko kernel module have been removed. 1263 Due to stability concerns, asynchronous I/O requests are only 1264 permitted on sockets and raw disks by default. To enable 1265 asynchronous I/O requests on all file types, set the 1266 vfs.aio.enable_unsafe sysctl to a non-zero value. 1267 126820160226: 1269 The ELF object manipulation tool objcopy is now provided by the 1270 ELF Tool Chain project rather than by GNU binutils. It should be a 1271 drop-in replacement, with the addition of arm64 support. The 1272 (temporary) src.conf knob WITHOUT_ELFCOPY_AS_OBJCOPY knob may be set 1273 to obtain the GNU version if necessary. 1274 127520160129: 1276 Building ZFS pools on top of zvols is prohibited by default. That 1277 feature has never worked safely; it's always been prone to deadlocks. 1278 Using a zvol as the backing store for a VM guest's virtual disk will 1279 still work, even if the guest is using ZFS. Legacy behavior can be 1280 restored by setting vfs.zfs.vol.recursive=1. 1281 128220160119: 1283 The NONE and HPN patches has been removed from OpenSSH. They are 1284 still available in the security/openssh-portable port. 1285 128620160113: 1287 With the addition of ypldap(8), a new _ypldap user is now required 1288 during installworld. "mergemaster -p" can be used to add the user 1289 prior to installworld, as documented in the handbook. 1290 129120151216: 1292 The tftp loader (pxeboot) now uses the option root-path directive. As a 1293 consequence it no longer looks for a pxeboot.4th file on the tftp 1294 server. Instead it uses the regular /boot infrastructure as with the 1295 other loaders. 1296 129720151211: 1298 The code to start recording plug and play data into the modules has 1299 been committed. While the old tools will properly build a new kernel, 1300 a number of warnings about "unknown metadata record 4" will be produced 1301 for an older kldxref. To avoid such warnings, make sure to rebuild 1302 the kernel toolchain (or world). Make sure that you have r292078 or 1303 later when trying to build 292077 or later before rebuilding. 1304 130520151207: 1306 Debug data files are now built by default with 'make buildworld' and 1307 installed with 'make installworld'. This facilitates debugging but 1308 requires more disk space both during the build and for the installed 1309 world. Debug files may be disabled by setting WITHOUT_DEBUG_FILES=yes 1310 in src.conf(5). 1311 131220151130: 1313 r291527 changed the internal interface between the nfsd.ko and 1314 nfscommon.ko modules. As such, they must both be upgraded to-gether. 1315 __FreeBSD_version has been bumped because of this. 1316 131720151108: 1318 Add support for unicode collation strings leads to a change of 1319 order of files listed by ls(1) for example. To get back to the old 1320 behaviour, set LC_COLLATE environment variable to "C". 1321 1322 Databases administrators will need to reindex their databases given 1323 collation results will be different. 1324 1325 Due to a bug in install(1) it is recommended to remove the ancient 1326 locales before running make installworld. 1327 1328 rm -rf /usr/share/locale/* 1329 133020151030: 1331 The OpenSSL has been upgraded to 1.0.2d. Any binaries requiring 1332 libcrypto.so.7 or libssl.so.7 must be recompiled. 1333 133420151020: 1335 Qlogic 24xx/25xx firmware images were updated from 5.5.0 to 7.3.0. 1336 Kernel modules isp_2400_multi and isp_2500_multi were removed and 1337 should be replaced with isp_2400 and isp_2500 modules respectively. 1338 133920151017: 1340 The build previously allowed using 'make -n' to not recurse into 1341 sub-directories while showing what commands would be executed, and 1342 'make -n -n' to recursively show commands. Now 'make -n' will recurse 1343 and 'make -N' will not. 1344 134520151012: 1346 If you specify SENDMAIL_MC or SENDMAIL_CF in make.conf, mergemaster 1347 and etcupdate will now use this file. A custom sendmail.cf is now 1348 updated via this mechanism rather than via installworld. If you had 1349 excluded sendmail.cf in mergemaster.rc or etcupdate.conf, you may 1350 want to remove the exclusion or change it to "always install". 1351 /etc/mail/sendmail.cf is now managed the same way regardless of 1352 whether SENDMAIL_MC/SENDMAIL_CF is used. If you are not using 1353 SENDMAIL_MC/SENDMAIL_CF there should be no change in behavior. 1354 135520151011: 1356 Compatibility shims for legacy ATA device names have been removed. 1357 It includes ATA_STATIC_ID kernel option, kern.cam.ada.legacy_aliases 1358 and kern.geom.raid.legacy_aliases loader tunables, kern.devalias.* 1359 environment variables, /dev/ad* and /dev/ar* symbolic links. 1360 136120151006: 1362 Clang, llvm, lldb, compiler-rt and libc++ have been upgraded to 3.7.0. 1363 Please see the 20141231 entry below for information about prerequisites 1364 and upgrading, if you are not already using clang 3.5.0 or higher. 1365 136620150924: 1367 Kernel debug files have been moved to /usr/lib/debug/boot/kernel/, 1368 and renamed from .symbols to .debug. This reduces the size requirements 1369 on the boot partition or file system and provides consistency with 1370 userland debug files. 1371 1372 When using the supported kernel installation method the 1373 /usr/lib/debug/boot/kernel directory will be renamed (to kernel.old) 1374 as is done with /boot/kernel. 1375 1376 Developers wishing to maintain the historical behavior of installing 1377 debug files in /boot/kernel/ can set KERN_DEBUGDIR="" in src.conf(5). 1378 137920150827: 1380 The wireless drivers had undergone changes that remove the 'parent 1381 interface' from the ifconfig -l output. The rc.d network scripts 1382 used to check presence of a parent interface in the list, so old 1383 scripts would fail to start wireless networking. Thus, etcupdate(3) 1384 or mergemaster(8) run is required after kernel update, to update your 1385 rc.d scripts in /etc. 1386 138720150827: 1388 pf no longer supports 'scrub fragment crop' or 'scrub fragment drop-ovl' 1389 These configurations are now automatically interpreted as 1390 'scrub fragment reassemble'. 1391 139220150817: 1393 Kernel-loadable modules for the random(4) device are back. To use 1394 them, the kernel must have 1395 1396 device random 1397 options RANDOM_LOADABLE 1398 1399 kldload(8) can then be used to load random_fortuna.ko 1400 or random_yarrow.ko. Please note that due to the indirect 1401 function calls that the loadable modules need to provide, 1402 the build-in variants will be slightly more efficient. 1403 1404 The random(4) kernel option RANDOM_DUMMY has been retired due to 1405 unpopularity. It was not all that useful anyway. 1406 140720150813: 1408 The WITHOUT_ELFTOOLCHAIN_TOOLS src.conf(5) knob has been retired. 1409 Control over building the ELF Tool Chain tools is now provided by 1410 the WITHOUT_TOOLCHAIN knob. 1411 141220150810: 1413 The polarity of Pulse Per Second (PPS) capture events with the 1414 uart(4) driver has been corrected. Prior to this change the PPS 1415 "assert" event corresponded to the trailing edge of a positive PPS 1416 pulse and the "clear" event was the leading edge of the next pulse. 1417 1418 As the width of a PPS pulse in a typical GPS receiver is on the 1419 order of 1 millisecond, most users will not notice any significant 1420 difference with this change. 1421 1422 Anyone who has compensated for the historical polarity reversal by 1423 configuring a negative offset equal to the pulse width will need to 1424 remove that workaround. 1425 142620150809: 1427 The default group assigned to /dev/dri entries has been changed 1428 from 'wheel' to 'video' with the id of '44'. If you want to have 1429 access to the dri devices please add yourself to the video group 1430 with: 1431 1432 # pw groupmod video -m $USER 1433 143420150806: 1435 The menu.rc and loader.rc files will now be replaced during 1436 upgrades. Please migrate local changes to menu.rc.local and 1437 loader.rc.local instead. 1438 143920150805: 1440 GNU Binutils versions of addr2line, c++filt, nm, readelf, size, 1441 strings and strip have been removed. The src.conf(5) knob 1442 WITHOUT_ELFTOOLCHAIN_TOOLS no longer provides the binutils tools. 1443 144420150728: 1445 As ZFS requires more kernel stack pages than is the default on some 1446 architectures e.g. i386, it now warns if KSTACK_PAGES is less than 1447 ZFS_MIN_KSTACK_PAGES (which is 4 at the time of writing). 1448 1449 Please consider using 'options KSTACK_PAGES=X' where X is greater 1450 than or equal to ZFS_MIN_KSTACK_PAGES i.e. 4 in such configurations. 1451 145220150706: 1453 sendmail has been updated to 8.15.2. Starting with FreeBSD 11.0 1454 and sendmail 8.15, sendmail uses uncompressed IPv6 addresses by 1455 default, i.e., they will not contain "::". For example, instead 1456 of ::1, it will be 0:0:0:0:0:0:0:1. This permits a zero subnet 1457 to have a more specific match, such as different map entries for 1458 IPv6:0:0 vs IPv6:0. This change requires that configuration 1459 data (including maps, files, classes, custom ruleset, etc.) must 1460 use the same format, so make certain such configuration data is 1461 upgrading. As a very simple check search for patterns like 1462 'IPv6:[0-9a-fA-F:]*::' and 'IPv6::'. To return to the old 1463 behavior, set the m4 option confUSE_COMPRESSED_IPV6_ADDRESSES or 1464 the cf option UseCompressedIPv6Addresses. 1465 146620150630: 1467 The default kernel entropy-processing algorithm is now 1468 Fortuna, replacing Yarrow. 1469 1470 Assuming you have 'device random' in your kernel config 1471 file, the configurations allow a kernel option to override 1472 this default. You may choose *ONE* of: 1473 1474 options RANDOM_YARROW # Legacy /dev/random algorithm. 1475 options RANDOM_DUMMY # Blocking-only driver. 1476 1477 If you have neither, you get Fortuna. For most people, 1478 read no further, Fortuna will give a /dev/random that works 1479 like it always used to, and the difference will be irrelevant. 1480 1481 If you remove 'device random', you get *NO* kernel-processed 1482 entropy at all. This may be acceptable to folks building 1483 embedded systems, but has complications. Carry on reading, 1484 and it is assumed you know what you need. 1485 1486 *PLEASE* read random(4) and random(9) if you are in the 1487 habit of tweaking kernel configs, and/or if you are a member 1488 of the embedded community, wanting specific and not-usual 1489 behaviour from your security subsystems. 1490 1491 NOTE!! If you use RANDOM_DUMMY and/or have no 'device 1492 random', you will NOT have a functioning /dev/random, and 1493 many cryptographic features will not work, including SSH. 1494 You may also find strange behaviour from the random(3) set 1495 of library functions, in particular sranddev(3), srandomdev(3) 1496 and arc4random(3). The reason for this is that the KERN_ARND 1497 sysctl only returns entropy if it thinks it has some to 1498 share, and with RANDOM_DUMMY or no 'device random' this 1499 will never happen. 1500 150120150623: 1502 An additional fix for the issue described in the 20150614 sendmail 1503 entry below has been committed in revision 284717. 1504 150520150616: 1506 FreeBSD's old make (fmake) has been removed from the system. It is 1507 available as the devel/fmake port or via pkg install fmake. 1508 150920150615: 1510 The fix for the issue described in the 20150614 sendmail entry 1511 below has been committed in revision 284436. The work 1512 around described in that entry is no longer needed unless the 1513 default setting is overridden by a confDH_PARAMETERS configuration 1514 setting of '5' or pointing to a 512 bit DH parameter file. 1515 151620150614: 1517 ALLOW_DEPRECATED_ATF_TOOLS/ATFFILE support has been removed from 1518 atf.test.mk (included from bsd.test.mk). Please upgrade devel/atf 1519 and devel/kyua to version 0.20+ and adjust any calling code to work 1520 with Kyuafile and kyua. 1521 152220150614: 1523 The import of openssl to address the FreeBSD-SA-15:10.openssl 1524 security advisory includes a change which rejects handshakes 1525 with DH parameters below 768 bits. sendmail releases prior 1526 to 8.15.2 (not yet released), defaulted to a 512 bit 1527 DH parameter setting for client connections. To work around 1528 this interoperability, sendmail can be configured to use a 1529 2048 bit DH parameter by: 1530 1531 1. Edit /etc/mail/`hostname`.mc 1532 2. If a setting for confDH_PARAMETERS does not exist or 1533 exists and is set to a string beginning with '5', 1534 replace it with '2'. 1535 3. If a setting for confDH_PARAMETERS exists and is set to 1536 a file path, create a new file with: 1537 openssl dhparam -out /path/to/file 2048 1538 4. Rebuild the .cf file: 1539 cd /etc/mail/; make; make install 1540 5. Restart sendmail: 1541 cd /etc/mail/; make restart 1542 1543 A sendmail patch is coming, at which time this file will be 1544 updated. 1545 154620150604: 1547 Generation of legacy formatted entries have been disabled by default 1548 in pwd_mkdb(8), as all base system consumers of the legacy formatted 1549 entries were converted to use the new format by default when the new, 1550 machine independent format have been added and supported since FreeBSD 1551 5.x. 1552 1553 Please see the pwd_mkdb(8) manual page for further details. 1554 155520150525: 1556 Clang and llvm have been upgraded to 3.6.1 release. Please see the 1557 20141231 entry below for information about prerequisites and upgrading, 1558 if you are not already using 3.5.0 or higher. 1559 156020150521: 1561 TI platform code switched to using vendor DTS files and this update 1562 may break existing systems running on Beaglebone, Beaglebone Black, 1563 and Pandaboard: 1564 1565 - dtb files should be regenerated/reinstalled. Filenames are the 1566 same but content is different now 1567 - GPIO addressing was changed, now each GPIO bank (32 pins per bank) 1568 has its own /dev/gpiocX device, e.g. pin 121 on /dev/gpioc0 in old 1569 addressing scheme is now pin 25 on /dev/gpioc3. 1570 - Pandaboard: /etc/ttys should be updated, serial console device is 1571 now /dev/ttyu2, not /dev/ttyu0 1572 157320150501: 1574 soelim(1) from gnu/usr.bin/groff has been replaced by usr.bin/soelim. 1575 If you need the GNU extension from groff soelim(1), install groff 1576 from package: pkg install groff, or via ports: textproc/groff. 1577 157820150423: 1579 chmod, chflags, chown and chgrp now affect symlinks in -R mode as 1580 defined in symlink(7); previously symlinks were silently ignored. 1581 158220150415: 1583 The const qualifier has been removed from iconv(3) to comply with 1584 POSIX. The ports tree is aware of this from r384038 onwards. 1585 158620150416: 1587 Libraries specified by LIBADD in Makefiles must have a corresponding 1588 DPADD_<lib> variable to ensure correct dependencies. This is now 1589 enforced in src.libnames.mk. 1590 159120150324: 1592 From legacy ata(4) driver was removed support for SATA controllers 1593 supported by more functional drivers ahci(4), siis(4) and mvs(4). 1594 Kernel modules ataahci and ataadaptec were removed completely, 1595 replaced by ahci and mvs modules respectively. 1596 159720150315: 1598 Clang, llvm and lldb have been upgraded to 3.6.0 release. Please see 1599 the 20141231 entry below for information about prerequisites and 1600 upgrading, if you are not already using 3.5.0 or higher. 1601 160220150307: 1603 The 32-bit PowerPC kernel has been changed to a position-independent 1604 executable. This can only be booted with a version of loader(8) 1605 newer than January 31, 2015, so make sure to update both world and 1606 kernel before rebooting. 1607 160820150217: 1609 If you are running a -CURRENT kernel since r273872 (Oct 30th, 2014), 1610 but before r278950, the RNG was not seeded properly. Immediately 1611 upgrade the kernel to r278950 or later and regenerate any keys (e.g. 1612 ssh keys or openssl keys) that were generated w/ a kernel from that 1613 range. This does not affect programs that directly used /dev/random 1614 or /dev/urandom. All userland uses of arc4random(3) are affected. 1615 161620150210: 1617 The autofs(4) ABI was changed in order to restore binary compatibility 1618 with 10.1-RELEASE. The automountd(8) daemon needs to be rebuilt to work 1619 with the new kernel. 1620 162120150131: 1622 The powerpc64 kernel has been changed to a position-independent 1623 executable. This can only be booted with a new version of loader(8), 1624 so make sure to update both world and kernel before rebooting. 1625 162620150118: 1627 Clang and llvm have been upgraded to 3.5.1 release. This is a bugfix 1628 only release, no new features have been added. Please see the 20141231 1629 entry below for information about prerequisites and upgrading, if you 1630 are not already using 3.5.0. 1631 163220150107: 1633 ELF tools addr2line, elfcopy (strip), nm, size, and strings are now 1634 taken from the ELF Tool Chain project rather than GNU binutils. They 1635 should be drop-in replacements, with the addition of arm64 support. 1636 The WITHOUT_ELFTOOLCHAIN_TOOLS= knob may be used to obtain the 1637 binutils tools, if necessary. See 20150805 for updated information. 1638 163920150105: 1640 The default Unbound configuration now enables remote control 1641 using a local socket. Users who have already enabled the 1642 local_unbound service should regenerate their configuration 1643 by running "service local_unbound setup" as root. 1644 164520150102: 1646 The GNU texinfo and GNU info pages have been removed. 1647 To be able to view GNU info pages please install texinfo from ports. 1648 164920141231: 1650 Clang, llvm and lldb have been upgraded to 3.5.0 release. 1651 1652 As of this release, a prerequisite for building clang, llvm and lldb is 1653 a C++11 capable compiler and C++11 standard library. This means that to 1654 be able to successfully build the cross-tools stage of buildworld, with 1655 clang as the bootstrap compiler, your system compiler or cross compiler 1656 should either be clang 3.3 or later, or gcc 4.8 or later, and your 1657 system C++ library should be libc++, or libdstdc++ from gcc 4.8 or 1658 later. 1659 1660 On any standard FreeBSD 10.x or 11.x installation, where clang and 1661 libc++ are on by default (that is, on x86 or arm), this should work out 1662 of the box. 1663 1664 On 9.x installations where clang is enabled by default, e.g. on x86 and 1665 powerpc, libc++ will not be enabled by default, so libc++ should be 1666 built (with clang) and installed first. If both clang and libc++ are 1667 missing, build clang first, then use it to build libc++. 1668 1669 On 8.x and earlier installations, upgrade to 9.x first, and then follow 1670 the instructions for 9.x above. 1671 1672 Sparc64 and mips users are unaffected, as they still use gcc 4.2.1 by 1673 default, and do not build clang. 1674 1675 Many embedded systems are resource constrained, and will not be able to 1676 build clang in a reasonable time, or in some cases at all. In those 1677 cases, cross building bootable systems on amd64 is a workaround. 1678 1679 This new version of clang introduces a number of new warnings, of which 1680 the following are most likely to appear: 1681 1682 -Wabsolute-value 1683 1684 This warns in two cases, for both C and C++: 1685 * When the code is trying to take the absolute value of an unsigned 1686 quantity, which is effectively a no-op, and almost never what was 1687 intended. The code should be fixed, if at all possible. If you are 1688 sure that the unsigned quantity can be safely cast to signed, without 1689 loss of information or undefined behavior, you can add an explicit 1690 cast, or disable the warning. 1691 1692 * When the code is trying to take an absolute value, but the called 1693 abs() variant is for the wrong type, which can lead to truncation. 1694 If you want to disable the warning instead of fixing the code, please 1695 make sure that truncation will not occur, or it might lead to unwanted 1696 side-effects. 1697 1698 -Wtautological-undefined-compare and 1699 -Wundefined-bool-conversion 1700 1701 These warn when C++ code is trying to compare 'this' against NULL, while 1702 'this' should never be NULL in well-defined C++ code. However, there is 1703 some legacy (pre C++11) code out there, which actively abuses this 1704 feature, which was less strictly defined in previous C++ versions. 1705 1706 Squid and openjdk do this, for example. The warning can be turned off 1707 for C++98 and earlier, but compiling the code in C++11 mode might result 1708 in unexpected behavior; for example, the parts of the program that are 1709 unreachable could be optimized away. 1710 171120141222: 1712 The old NFS client and server (kernel options NFSCLIENT, NFSSERVER) 1713 kernel sources have been removed. The .h files remain, since some 1714 utilities include them. This will need to be fixed later. 1715 If "mount -t oldnfs ..." is attempted, it will fail. 1716 If the "-o" option on mountd(8), nfsd(8) or nfsstat(1) is used, 1717 the utilities will report errors. 1718 171920141121: 1720 The handling of LOCAL_LIB_DIRS has been altered to skip addition of 1721 directories to top level SUBDIR variable when their parent 1722 directory is included in LOCAL_DIRS. Users with build systems with 1723 such hierarchies and without SUBDIR entries in the parent 1724 directory Makefiles should add them or add the directories to 1725 LOCAL_DIRS. 1726 172720141109: 1728 faith(4) and faithd(8) have been removed from the base system. Faith 1729 has been obsolete for a very long time. 1730 173120141104: 1732 vt(4), the new console driver, is enabled by default. It brings 1733 support for Unicode and double-width characters, as well as 1734 support for UEFI and integration with the KMS kernel video 1735 drivers. 1736 1737 You may need to update your console settings in /etc/rc.conf, 1738 most probably the keymap. During boot, /etc/rc.d/syscons will 1739 indicate what you need to do. 1740 1741 vt(4) still has issues and lacks some features compared to 1742 syscons(4). See the wiki for up-to-date information: 1743 https://wiki.freebsd.org/Newcons 1744 1745 If you want to keep using syscons(4), you can do so by adding 1746 the following line to /boot/loader.conf: 1747 kern.vty=sc 1748 174920141102: 1750 pjdfstest has been integrated into kyua as an opt-in test suite. 1751 Please see share/doc/pjdfstest/README for more details on how to 1752 execute it. 1753 175420141009: 1755 gperf has been removed from the base system for architectures 1756 that use clang. Ports that require gperf will obtain it from the 1757 devel/gperf port. 1758 175920140923: 1760 pjdfstest has been moved from tools/regression/pjdfstest to 1761 contrib/pjdfstest . 1762 176320140922: 1764 At svn r271982, The default linux compat kernel ABI has been adjusted 1765 to 2.6.18 in support of the linux-c6 compat ports infrastructure 1766 update. If you wish to continue using the linux-f10 compat ports, 1767 add compat.linux.osrelease=2.6.16 to your local sysctl.conf. Users are 1768 encouraged to update their linux-compat packages to linux-c6 during 1769 their next update cycle. 1770 177120140729: 1772 The ofwfb driver, used to provide a graphics console on PowerPC when 1773 using vt(4), no longer allows mmap() of all physical memory. This 1774 will prevent Xorg on PowerPC with some ATI graphics cards from 1775 initializing properly unless x11-servers/xorg-server is updated to 1776 1.12.4_8 or newer. 1777 177820140723: 1779 The xdev targets have been converted to using TARGET and 1780 TARGET_ARCH instead of XDEV and XDEV_ARCH. 1781 178220140719: 1783 The default unbound configuration has been modified to address 1784 issues with reverse lookups on networks that use private 1785 address ranges. If you use the local_unbound service, run 1786 "service local_unbound setup" as root to regenerate your 1787 configuration, then "service local_unbound reload" to load the 1788 new configuration. 1789 179020140709: 1791 The GNU texinfo and GNU info pages are not built and installed 1792 anymore, WITH_INFO knob has been added to allow to built and install 1793 them again. 1794 UPDATE: see 20150102 entry on texinfo's removal 1795 179620140708: 1797 The GNU readline library is now an INTERNALLIB - that is, it is 1798 statically linked into consumers (GDB and variants) in the base 1799 system, and the shared library is no longer installed. The 1800 devel/readline port is available for third party software that 1801 requires readline. 1802 180320140702: 1804 The Itanium architecture (ia64) has been removed from the list of 1805 known architectures. This is the first step in the removal of the 1806 architecture. 1807 180820140701: 1809 Commit r268115 has added NFSv4.1 server support, merged from 1810 projects/nfsv4.1-server. Since this includes changes to the 1811 internal interfaces between the NFS related modules, a full 1812 build of the kernel and modules will be necessary. 1813 __FreeBSD_version has been bumped. 1814 181520140629: 1816 The WITHOUT_VT_SUPPORT kernel config knob has been renamed 1817 WITHOUT_VT. (The other _SUPPORT knobs have a consistent meaning 1818 which differs from the behaviour controlled by this knob.) 1819 182020140619: 1821 Maximal length of the serial number in CTL was increased from 16 to 1822 64 chars, that breaks ABI. All CTL-related tools, such as ctladm 1823 and ctld, need to be rebuilt to work with a new kernel. 1824 182520140606: 1826 The libatf-c and libatf-c++ major versions were downgraded to 0 and 1827 1 respectively to match the upstream numbers. They were out of 1828 sync because, when they were originally added to FreeBSD, the 1829 upstream versions were not respected. These libraries are private 1830 and not yet built by default, so renumbering them should be a 1831 non-issue. However, unclean source trees will yield broken test 1832 programs once the operator executes "make delete-old-libs" after a 1833 "make installworld". 1834 1835 Additionally, the atf-sh binary was made private by moving it into 1836 /usr/libexec/. Already-built shell test programs will keep the 1837 path to the old binary so they will break after "make delete-old" 1838 is run. 1839 1840 If you are using WITH_TESTS=yes (not the default), wipe the object 1841 tree and rebuild from scratch to prevent spurious test failures. 1842 This is only needed once: the misnumbered libraries and misplaced 1843 binaries have been added to OptionalObsoleteFiles.inc so they will 1844 be removed during a clean upgrade. 1845 184620140512: 1847 Clang and llvm have been upgraded to 3.4.1 release. 1848 184920140508: 1850 We bogusly installed src.opts.mk in /usr/share/mk. This file should 1851 be removed to avoid issues in the future (and has been added to 1852 ObsoleteFiles.inc). 1853 185420140505: 1855 /etc/src.conf now affects only builds of the FreeBSD src tree. In the 1856 past, it affected all builds that used the bsd.*.mk files. The old 1857 behavior was a bug, but people may have relied upon it. To get this 1858 behavior back, you can .include /etc/src.conf from /etc/make.conf 1859 (which is still global and isn't changed). This also changes the 1860 behavior of incremental builds inside the tree of individual 1861 directories. Set MAKESYSPATH to ".../share/mk" to do that. 1862 Although this has survived make universe and some upgrade scenarios, 1863 other upgrade scenarios may have broken. At least one form of 1864 temporary breakage was fixed with MAKESYSPATH settings for buildworld 1865 as well... In cases where MAKESYSPATH isn't working with this 1866 setting, you'll need to set it to the full path to your tree. 1867 1868 One side effect of all this cleaning up is that bsd.compiler.mk 1869 is no longer implicitly included by bsd.own.mk. If you wish to 1870 use COMPILER_TYPE, you must now explicitly include bsd.compiler.mk 1871 as well. 1872 187320140430: 1874 The lindev device has been removed since /dev/full has been made a 1875 standard device. __FreeBSD_version has been bumped. 1876 187720140424: 1878 The knob WITHOUT_VI was added to the base system, which controls 1879 building ex(1), vi(1), etc. Older releases of FreeBSD required ex(1) 1880 in order to reorder files share/termcap and didn't build ex(1) as a 1881 build tool, so building/installing with WITH_VI is highly advised for 1882 build hosts for older releases. 1883 1884 This issue has been fixed in stable/9 and stable/10 in r277022 and 1885 r276991, respectively. 1886 188720140418: 1888 The YES_HESIOD knob has been removed. It has been obsolete for 1889 a decade. Please move to using WITH_HESIOD instead or your builds 1890 will silently lack HESIOD. 1891 189220140405: 1893 The uart(4) driver has been changed with respect to its handling 1894 of the low-level console. Previously the uart(4) driver prevented 1895 any process from changing the baudrate or the CLOCAL and HUPCL 1896 control flags. By removing the restrictions, operators can make 1897 changes to the serial console port without having to reboot. 1898 However, when getty(8) is started on the serial device that is 1899 associated with the low-level console, a misconfigured terminal 1900 line in /etc/ttys will now have a real impact. 1901 Before upgrading the kernel, make sure that /etc/ttys has the 1902 serial console device configured as 3wire without baudrate to 1903 preserve the previous behaviour. E.g: 1904 ttyu0 "/usr/libexec/getty 3wire" vt100 on secure 1905 190620140306: 1907 Support for libwrap (TCP wrappers) in rpcbind was disabled by default 1908 to improve performance. To re-enable it, if needed, run rpcbind 1909 with command line option -W. 1910 191120140226: 1912 Switched back to the GPL dtc compiler due to updates in the upstream 1913 dts files not being supported by the BSDL dtc compiler. You will need 1914 to rebuild your kernel toolchain to pick up the new compiler. Core dumps 1915 may result while building dtb files during a kernel build if you fail 1916 to do so. Set WITHOUT_GPL_DTC if you require the BSDL compiler. 1917 191820140216: 1919 Clang and llvm have been upgraded to 3.4 release. 1920 192120140216: 1922 The nve(4) driver has been removed. Please use the nfe(4) driver 1923 for NVIDIA nForce MCP Ethernet adapters instead. 1924 192520140212: 1926 An ABI incompatibility crept into the libc++ 3.4 import in r261283. 1927 This could cause certain C++ applications using shared libraries built 1928 against the previous version of libc++ to crash. The incompatibility 1929 has now been fixed, but any C++ applications or shared libraries built 1930 between r261283 and r261801 should be recompiled. 1931 193220140204: 1933 OpenSSH will now ignore errors caused by kernel lacking of Capsicum 1934 capability mode support. Please note that enabling the feature in 1935 kernel is still highly recommended. 1936 193720140131: 1938 OpenSSH is now built with sandbox support, and will use sandbox as 1939 the default privilege separation method. This requires Capsicum 1940 capability mode support in kernel. 1941 194220140128: 1943 The libelf and libdwarf libraries have been updated to newer 1944 versions from upstream. Shared library version numbers for 1945 these two libraries were bumped. Any ports or binaries 1946 requiring these two libraries should be recompiled. 1947 __FreeBSD_version is bumped to 1100006. 1948 194920140110: 1950 If a Makefile in a tests/ directory was auto-generating a Kyuafile 1951 instead of providing an explicit one, this would prevent such 1952 Makefile from providing its own Kyuafile in the future during 1953 NO_CLEAN builds. This has been fixed in the Makefiles but manual 1954 intervention is needed to clean an objdir if you use NO_CLEAN: 1955 # find /usr/obj -name Kyuafile | xargs rm -f 1956 195720131213: 1958 The behavior of gss_pseudo_random() for the krb5 mechanism 1959 has changed, for applications requesting a longer random string 1960 than produced by the underlying enctype's pseudo-random() function. 1961 In particular, the random string produced from a session key of 1962 enctype aes256-cts-hmac-sha1-96 or aes256-cts-hmac-sha1-96 will 1963 be different at the 17th octet and later, after this change. 1964 The counter used in the PRF+ construction is now encoded as a 1965 big-endian integer in accordance with RFC 4402. 1966 __FreeBSD_version is bumped to 1100004. 1967 196820131108: 1969 The WITHOUT_ATF build knob has been removed and its functionality 1970 has been subsumed into the more generic WITHOUT_TESTS. If you were 1971 using the former to disable the build of the ATF libraries, you 1972 should change your settings to use the latter. 1973 197420131025: 1975 The default version of mtree is nmtree which is obtained from 1976 NetBSD. The output is generally the same, but may vary 1977 slightly. If you found you need identical output adding 1978 "-F freebsd9" to the command line should do the trick. For the 1979 time being, the old mtree is available as fmtree. 1980 198120131014: 1982 libbsdyml has been renamed to libyaml and moved to /usr/lib/private. 1983 This will break ports-mgmt/pkg. Rebuild the port, or upgrade to pkg 1984 1.1.4_8 and verify bsdyml not linked in, before running "make 1985 delete-old-libs": 1986 # make -C /usr/ports/ports-mgmt/pkg build deinstall install clean 1987 or 1988 # pkg install pkg; ldd /usr/local/sbin/pkg | grep bsdyml 1989 199020131010: 1991 The stable/10 branch has been created in subversion from head 1992 revision r256279. 1993 1994COMMON ITEMS: 1995 1996 General Notes 1997 ------------- 1998 Sometimes, obscure build problems are the result of environment 1999 poisoning. This can happen because the make utility reads its 2000 environment when searching for values for global variables. To run 2001 your build attempts in an "environmental clean room", prefix all make 2002 commands with 'env -i '. See the env(1) manual page for more details. 2003 Occasionally a build failure will occur with "make -j" due to a race 2004 condition. If this happens try building again without -j, and please 2005 report a bug if it happens consistently. 2006 2007 When upgrading from one major version to another it is generally best to 2008 upgrade to the latest code in the currently installed branch first, then 2009 do an upgrade to the new branch. This is the best-tested upgrade path, 2010 and has the highest probability of being successful. Please try this 2011 approach if you encounter problems with a major version upgrade. Since 2012 the stable 4.x branch point, one has generally been able to upgrade from 2013 anywhere in the most recent stable branch to head / current (or even the 2014 last couple of stable branches). See the top of this file when there's 2015 an exception. 2016 2017 The update process will emit an error on an attempt to perform a build 2018 or install from a FreeBSD version below the earliest supported version. 2019 When updating from an older version the update should be performed one 2020 major release at a time, including running `make delete-old` at each 2021 step. 2022 2023 When upgrading a live system, having a root shell around before 2024 installing anything can help undo problems. Not having a root shell 2025 around can lead to problems if pam has changed too much from your 2026 starting point to allow continued authentication after the upgrade. 2027 2028 This file should be read as a log of events. When a later event changes 2029 information of a prior event, the prior event should not be deleted. 2030 Instead, a pointer to the entry with the new information should be 2031 placed in the old entry. Readers of this file should also sanity check 2032 older entries before relying on them blindly. Authors of new entries 2033 should write them with this in mind. 2034 2035 ZFS notes 2036 --------- 2037 When upgrading the boot ZFS pool to a new version, always follow 2038 these two steps: 2039 2040 1.) recompile and reinstall the ZFS boot loader and boot block 2041 (this is part of "make buildworld" and "make installworld") 2042 2043 2.) update the ZFS boot block on your boot drive 2044 2045 The following example updates the ZFS boot block on the first 2046 partition (freebsd-boot) of a GPT partitioned drive ada0: 2047 "gpart bootcode -p /boot/gptzfsboot -i 1 ada0" 2048 2049 Non-boot pools do not need these updates. 2050 2051 To build a kernel 2052 ----------------- 2053 If you are updating from a prior version of FreeBSD (even one just 2054 a few days old), you should follow this procedure. It is the most 2055 failsafe as it uses a /usr/obj tree with a fresh mini-buildworld, 2056 2057 make kernel-toolchain 2058 make -DALWAYS_CHECK_MAKE buildkernel KERNCONF=YOUR_KERNEL_HERE 2059 make -DALWAYS_CHECK_MAKE installkernel KERNCONF=YOUR_KERNEL_HERE 2060 2061 To test a kernel once 2062 --------------------- 2063 If you just want to boot a kernel once (because you are not sure 2064 if it works, or if you want to boot a known bad kernel to provide 2065 debugging information) run 2066 make installkernel KERNCONF=YOUR_KERNEL_HERE KODIR=/boot/testkernel 2067 nextboot -k testkernel 2068 2069 To rebuild everything and install it on the current system. 2070 ----------------------------------------------------------- 2071 # Note: sometimes if you are running current you gotta do more than 2072 # is listed here if you are upgrading from a really old current. 2073 2074 <make sure you have good level 0 dumps> 2075 make buildworld 2076 make buildkernel KERNCONF=YOUR_KERNEL_HERE 2077 make installkernel KERNCONF=YOUR_KERNEL_HERE 2078 [1] 2079 <reboot in single user> [3] 2080 mergemaster -Fp [5] 2081 make installworld 2082 mergemaster -Fi [4] 2083 make delete-old [6] 2084 <reboot> 2085 2086 To cross-install current onto a separate partition 2087 -------------------------------------------------- 2088 # In this approach we use a separate partition to hold 2089 # current's root, 'usr', and 'var' directories. A partition 2090 # holding "/", "/usr" and "/var" should be about 2GB in 2091 # size. 2092 2093 <make sure you have good level 0 dumps> 2094 <boot into -stable> 2095 make buildworld 2096 make buildkernel KERNCONF=YOUR_KERNEL_HERE 2097 <maybe newfs current's root partition> 2098 <mount current's root partition on directory ${CURRENT_ROOT}> 2099 make installworld DESTDIR=${CURRENT_ROOT} -DDB_FROM_SRC 2100 make distribution DESTDIR=${CURRENT_ROOT} # if newfs'd 2101 make installkernel KERNCONF=YOUR_KERNEL_HERE DESTDIR=${CURRENT_ROOT} 2102 cp /etc/fstab ${CURRENT_ROOT}/etc/fstab # if newfs'd 2103 <edit ${CURRENT_ROOT}/etc/fstab to mount "/" from the correct partition> 2104 <reboot into current> 2105 <do a "native" rebuild/install as described in the previous section> 2106 <maybe install compatibility libraries from ports/misc/compat*> 2107 <reboot> 2108 2109 2110 To upgrade in-place from stable to current 2111 ---------------------------------------------- 2112 <make sure you have good level 0 dumps> 2113 make buildworld [9] 2114 make buildkernel KERNCONF=YOUR_KERNEL_HERE [8] 2115 make installkernel KERNCONF=YOUR_KERNEL_HERE 2116 [1] 2117 <reboot in single user> [3] 2118 mergemaster -Fp [5] 2119 make installworld 2120 mergemaster -Fi [4] 2121 make delete-old [6] 2122 <reboot> 2123 2124 Make sure that you've read the UPDATING file to understand the 2125 tweaks to various things you need. At this point in the life 2126 cycle of current, things change often and you are on your own 2127 to cope. The defaults can also change, so please read ALL of 2128 the UPDATING entries. 2129 2130 Also, if you are tracking -current, you must be subscribed to 2131 freebsd-current@freebsd.org. Make sure that before you update 2132 your sources that you have read and understood all the recent 2133 messages there. If in doubt, please track -stable which has 2134 much fewer pitfalls. 2135 2136 [1] If you have third party modules, such as vmware, you 2137 should disable them at this point so they don't crash your 2138 system on reboot. 2139 2140 [3] From the bootblocks, boot -s, and then do 2141 fsck -p 2142 mount -u / 2143 mount -a 2144 sh /etc/rc.d/zfs start # mount zfs filesystem, if needed 2145 cd src # full path to source 2146 adjkerntz -i # if CMOS is wall time 2147 Also, when doing a major release upgrade, it is required that 2148 you boot into single user mode to do the installworld. 2149 2150 [4] Note: This step is non-optional. Failure to do this step 2151 can result in a significant reduction in the functionality of the 2152 system. Attempting to do it by hand is not recommended and those 2153 that pursue this avenue should read this file carefully, as well 2154 as the archives of freebsd-current and freebsd-hackers mailing lists 2155 for potential gotchas. The -U option is also useful to consider. 2156 See mergemaster(8) for more information. 2157 2158 [5] Usually this step is a no-op. However, from time to time 2159 you may need to do this if you get unknown user in the following 2160 step. It never hurts to do it all the time. You may need to 2161 install a new mergemaster (cd src/usr.sbin/mergemaster && make 2162 install) after the buildworld before this step if you last updated 2163 from current before 20130425 or from -stable before 20130430. 2164 2165 [6] This only deletes old files and directories. Old libraries 2166 can be deleted by "make delete-old-libs", but you have to make 2167 sure that no program is using those libraries anymore. 2168 2169 [8] The new kernel must be able to run existing binaries used by an 2170 installworld. When upgrading across major versions, the new kernel's 2171 configuration must include the correct COMPAT_FREEBSD<n> option for 2172 existing binaries (e.g. COMPAT_FREEBSD11 to run 11.x binaries). Failure 2173 to do so may leave you with a system that is hard to boot to recover. A 2174 GENERIC kernel will include suitable compatibility options to run 2175 binaries from older branches. Note that the ability to run binaries 2176 from unsupported branches is not guaranteed. 2177 2178 Make sure that you merge any new devices from GENERIC since the 2179 last time you updated your kernel config file. Options also 2180 change over time, so you may need to adjust your custom kernels 2181 for these as well. 2182 2183 [9] If CPUTYPE is defined in your /etc/make.conf, make sure to use the 2184 "?=" instead of the "=" assignment operator, so that buildworld can 2185 override the CPUTYPE if it needs to. 2186 2187 MAKEOBJDIRPREFIX must be defined in an environment variable, and 2188 not on the command line, or in /etc/make.conf. buildworld will 2189 warn if it is improperly defined. 2190FORMAT: 2191 2192This file contains a list, in reverse chronological order, of major 2193breakages in tracking -current. It is not guaranteed to be a complete 2194list of such breakages, and only contains entries since September 23, 2011. 2195If you need to see UPDATING entries from before that date, you will need 2196to fetch an UPDATING file from an older FreeBSD release. 2197 2198Copyright information: 2199 2200Copyright 1998-2009 M.
