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 2920200424: 30 closefrom(2) has been moved under COMPAT12, and replaced in libc with a 31 stub that calls close_range(2). If using a custom kernel configuration, 32 you may want to ensure that the COMPAT_FREEBSD12 option is included, as 33 a slightly older -CURRENT userland and older FreeBSD userlands may not 34 be functional without closefrom(2). 35 3620200414: 37 Upstream DTS from Linux 5.6 was merged and they now have the SID 38 and THS (Secure ID controller and THermal Sensor) node present. 39 The DTB overlays have now been removed from the tree for the H3/H5 and 40 A64 SoCs and the aw_sid and aw_thermal driver have been updated to 41 deal with upstream DTS. If you are using those overlays you need to 42 remove them from loader.conf and update the DTBs on the FAT partition. 43 4420200310: 45 Clang, llvm, lld, lldb, compiler-rt, libc++, libunwind and openmp have 46 been upgraded to 10.0.0. Please see the 20141231 entry below for 47 information about prerequisites and upgrading, if you are not already 48 using clang 3.5.0 or higher. 49 5020200309: 51 The amd(8) automount daemon has been removed from the source tree. 52 As of FreeBSD 10.1 autofs(5) is the preferred tool for automounting. 53 amd is still available in the sysutils/am-utils port. 54 5520200301: 56 Removed brooktree driver (bktr.4) from the tree. 57 5820200229: 59 The WITH_GPL_DTC option has been removed. The BSD-licenced device tree 60 compiler in usr.bin/dtc is used on all architectures which use dtc, and 61 the GPL dtc is available (if needed) from the sysutils/dtc port. 62 6320200229: 64 The WITHOUT_LLVM_LIBUNWIND option has been removed. LLVM's libunwind 65 is used by all supported CPU architectures. 66 6720200229: 68 GCC 4.2.1 has been removed from the tree. The WITH_GCC, 69 WITH_GCC_BOOTSTRAP, and WITH_GNUCXX options are no longer available. 70 Users who wish to build FreeBSD with GCC must use the external toolchain 71 ports or packages. 72 7320200220: 74 ncurses has been updated to a newer version (6.2-20200215). Given the ABI 75 has changed, users will have to rebuild all the ports that are linked to 76 ncurses. 77 7820200217: 79 The size of struct vnet and the magic cookie have changed. 80 Users need to recompile libkvm and all modules using VIMAGE 81 together with their new kernel. 82 8320200212: 84 Defining the long deprecated NO_CTF, NO_DEBUG_FILES, NO_INSTALLLIB, 85 NO_MAN, NO_PROFILE, and NO_WARNS variables is now an error. Update 86 your Makefiles and scripts to define MK_<var>=no instead as required. 87 88 One exception to this is that program or library Makefiles should 89 define MAN to empty rather than setting MK_MAN=no. 90 9120200108: 92 Clang/LLVM is now the default compiler and LLD the default 93 linker for riscv64. 94 9520200107: 96 make universe no longer uses GCC 4.2.1 on any architectures. 97 Architectures not supported by in-tree Clang/LLVM require an 98 external toolchain package. 99 10020200104: 101 GCC 4.2.1 is now not built by default, as part of the GCC 4.2.1 102 retirement plan. Specifically, the GCC, GCC_BOOTSTRAP, and GNUCXX 103 options default to off for all supported CPU architectures. As a 104 short-term transition aid they may be enabled via WITH_* options. 105 GCC 4.2.1 is expected to be removed from the tree on 2020-03-31. 106 10720200102: 108 Support for armv5 has been disconnected and is being removed. The 109 machine combination MACHINE=arm MACHINE_ARCH=arm is no longer valid. 110 You must now use a MACHINE_ARCH of armv6 or armv7. The default 111 MACHINE_ARCH for MACHINE=arm is now armv7. 112 11320191226: 114 Clang/LLVM is now the default compiler for all powerpc architectures. 115 LLD is now the default linker for powerpc64. The change for powerpc64 116 also includes a change to the ELFv2 ABI, incompatible with the existing 117 ABI. 118 11920191226: 120 Kernel-loadable random(4) modules are no longer unloadable. 121 12220191222: 123 Clang, llvm, lld, lldb, compiler-rt, libc++, libunwind and openmp have 124 been upgraded to 9.0.1. Please see the 20141231 entry below for 125 information about prerequisites and upgrading, if you are not already 126 using clang 3.5.0 or higher. 127 12820191212: 129 r355677 has modified the internal interface used between the 130 NFS modules in the kernel. As such, they must all be upgraded 131 simultaneously. I will do a version bump for this. 132 13320191205: 134 The root certificates of the Mozilla CA Certificate Store have been 135 imported into the base system and can be managed with the certctl(8) 136 utility. If you have installed the security/ca_root_nss port or package 137 with the ETCSYMLINK option (the default), be advised that there may be 138 differences between those included in the port and those included in 139 base due to differences in nss branch used as well as general update 140 frequency. Note also that certctl(8) cannot manage certs in the 141 format used by the security/ca_root_nss port. 142 14320191120: 144 The amd(8) automount daemon has been disabled by default, and will be 145 removed in the future. As of FreeBSD 10.1 the autofs(5) is available 146 for automounting. 147 14820191107: 149 The nctgpio and wbwd drivers have been moved to the superio bus. 150 If you have one of these drivers in a kernel configuration, then 151 you should add device superio to it. If you use one of these drivers 152 as a module and you compile a custom set of modules, then you should 153 add superio to the set. 154 15520191021: 156 KPIs for network drivers to access interface addresses have changed. 157 Users need to recompile NIC driver modules together with kernel. 158 15920191021: 160 The net.link.tap.user_open sysctl no longer prevents user opening of 161 already created /dev/tapNN devices. Access is still controlled by 162 node permissions, just like tun devices. The net.link.tap.user_open 163 sysctl is now used only to allow users to perform devfs cloning of 164 tap devices, and the subsequent open may not succeed if the user is not 165 in the appropriate group. This sysctl may be deprecated/removed 166 completely in the future. 167 16820191009: 169 mips, powerpc, and sparc64 are no longer built as part of 170 universe / tinderbox unless MAKE_OBSOLETE_GCC is defined. If 171 not defined, mips, powerpc, and sparc64 builds will look for 172 the xtoolchain binaries and if installed use them for universe 173 builds. As llvm 9.0 becomes vetted for these architectures, they 174 will be removed from the list. 175 17620191009: 177 Clang, llvm, lld, lldb, compiler-rt, libc++, libunwind and openmp have 178 been upgraded to 9.0.0. Please see the 20141231 entry below for 179 information about prerequisites and upgrading, if you are not already 180 using clang 3.5.0 or higher. 181 18220191003: 183 The hpt27xx, hptmv, hptnr, and hptrr drivers have been removed from 184 GENERIC. They are available as modules and can be loaded by adding 185 to /boot/loader.conf hpt27xx_load="YES", hptmv_load="YES", 186 hptnr_load="YES", or hptrr_load="YES", respectively. 187 18820190913: 189 ntpd no longer by default locks its pages in memory, allowing them 190 to be paged out by the kernel. Use rlimit memlock to restore 191 historic BSD behaviour. For example, add "rlimit memlock 32" 192 to ntp.conf to lock up to 32 MB of ntpd address space in memory. 193 19420190823: 195 Several of ping6's options have been renamed for better consistency 196 with ping. If you use any of -ARWXaghmrtwx, you must update your 197 scripts. See ping6(8) for details. 198 19920190727: 200 The vfs.fusefs.sync_unmount and vfs.fusefs.init_backgrounded sysctls 201 and the "-o sync_unmount" and "-o init_backgrounded" mount options have 202 been removed from mount_fusefs(8). You can safely remove them from 203 your scripts, because they had no effect. 204 205 The vfs.fusefs.fix_broken_io, vfs.fusefs.sync_resize, 206 vfs.fusefs.refresh_size, vfs.fusefs.mmap_enable, 207 vfs.fusefs.reclaim_revoked, and vfs.fusefs.data_cache_invalidate 208 sysctls have been removed. If you felt the need to set any of them to 209 a non-default value, please tell asomers@FreeBSD.org why. 210 21120190713: 212 Default permissions on the /var/account/acct file (and copies of it 213 rotated by periodic daily scripts) are changed from 0644 to 0640 214 because the file contains sensitive information that should not be 215 world-readable. If the /var/account directory must be created by 216 rc.d/accounting, the mode used is now 0750. Admins who use the 217 accounting feature are encouraged to change the mode of an existing 218 /var/account directory to 0750 or 0700. 219 22020190620: 221 Entropy collection and the /dev/random device are no longer optional 222 components. The "device random" option has been removed. 223 Implementations of distilling algorithms can still be made loadable 224 with "options RANDOM_LOADABLE" (e.g., random_fortuna.ko). 225 22620190612: 227 Clang, llvm, lld, lldb, compiler-rt, libc++, libunwind and openmp have 228 been upgraded to 8.0.1. Please see the 20141231 entry below for 229 information about prerequisites and upgrading, if you are not already 230 using clang 3.5.0 or higher. 231 23220190608: 233 A fix was applied to i386 kernel modules to avoid panics with 234 dpcpu or vnet. Users need to recompile i386 kernel modules 235 having pcpu or vnet sections or they will refuse to load. 236 23720190513: 238 User-wired pages now have their own counter, 239 vm.stats.vm.v_user_wire_count. The vm.max_wired sysctl was renamed 240 to vm.max_user_wired and changed from an unsigned int to an unsigned 241 long. bhyve VMs wired with the -S are now subject to the user 242 wiring limit; the vm.max_user_wired sysctl may need to be tuned to 243 avoid running into the limit. 244 24520190507: 246 The IPSEC option has been removed from GENERIC. Users requiring 247 ipsec(4) must now load the ipsec(4) kernel module. 248 24920190507: 250 The tap(4) driver has been folded into tun(4), and the module has been 251 renamed to tuntap. You should update any kld_list="if_tap" or 252 kld_list="if_tun" entries in /etc/rc.conf, if_tap_load="YES" or 253 if_tun_load="YES" entries in /boot/loader.conf to load the if_tuntap 254 module instead, and "device tap" or "device tun" entries in kernel 255 config files to select the tuntap device instead. 256 25720190418: 258 The following knobs have been added related to tradeoffs between 259 safe use of the random device and availability in the absence of 260 entropy: 261 262 kern.random.initial_seeding.bypass_before_seeding: tunable; set 263 non-zero to bypass the random device prior to seeding, or zero to 264 block random requests until the random device is initially seeded. 265 For now, set to 1 (unsafe) by default to restore pre-r346250 boot 266 availability properties. 267 268 kern.random.initial_seeding.read_random_bypassed_before_seeding: 269 read-only diagnostic sysctl that is set when bypass is enabled and 270 read_random(9) is bypassed, to enable programmatic handling of this 271 initial condition, if desired. 272 273 kern.random.initial_seeding.arc4random_bypassed_before_seeding: 274 Similar to the above, but for for arc4random(9) initial seeding. 275 276 kern.random.initial_seeding.disable_bypass_warnings: tunable; set 277 non-zero to disable warnings in dmesg when the same conditions are 278 met as for the diagnostic sysctls above. Defaults to zero, i.e., 279 produce warnings in dmesg when the conditions are met. 280 28120190416: 282 The loadable random module KPI has changed; the random_infra_init() 283 routine now requires a 3rd function pointer for a bool (*)(void) 284 method that returns true if the random device is seeded (and 285 therefore unblocked). 286 28720190404: 288 r345895 reverts r320698. This implies that an nfsuserd(8) daemon 289 built from head sources between r320757 (July 6, 2017) and 290 r338192 (Aug. 22, 2018) will not work unless the "-use-udpsock" 291 is added to the command line. 292 nfsuserd daemons built from head sources that are post-r338192 are 293 not affected and should continue to work. 294 29520190320: 296 The fuse(4) module has been renamed to fusefs(4) for consistency with 297 other filesystems. You should update any kld_load="fuse" entries in 298 /etc/rc.conf, fuse_load="YES" entries in /boot/loader.conf, and 299 "options FUSE" entries in kernel config files. 300 30120190304: 302 Clang, llvm, lld, lldb, compiler-rt and libc++ have been upgraded to 303 8.0.0. Please see the 20141231 entry below for information about 304 prerequisites and upgrading, if you are not already using clang 3.5.0 305 or higher. 306 30720190226: 308 geom_uzip(4) depends on the new module xz. If geom_uzip is statically 309 compiled into your custom kernel, add 'device xz' statement to the 310 kernel config. 311 31220190219: 313 drm and drm2 have been removed from the tree. Please see 314 https://wiki.freebsd.org/Graphics for the latest information on 315 migrating to the drm ports. 316 31720190131: 318 Iflib is no longer unconditionally compiled into the kernel. Drivers 319 using iflib and statically compiled into the kernel, now require 320 the 'device iflib' config option. For the same drivers loaded as 321 modules on kernels not having 'device iflib', the iflib.ko module 322 is loaded automatically. 323 32420190125: 325 The IEEE80211_AMPDU_AGE and AH_SUPPORT_AR5416 kernel configuration 326 options no longer exist since r343219 and r343427 respectively; 327 nothing uses them, so they should be just removed from custom 328 kernel config files. 329 33020181230: 331 r342635 changes the way efibootmgr(8) works by requiring users to add 332 the -b (bootnum) parameter for commands where the bootnum was previously 333 specified with each option. For example 'efibootmgr -B 0001' is now 334 'efibootmgr -B -b 0001'. 335 33620181220: 337 r342286 modifies the NFSv4 server so that it obeys vfs.nfsd.nfs_privport 338 in the same as it is applied to NFSv2 and 3. This implies that NFSv4 339 servers that have vfs.nfsd.nfs_privport set will only allow mounts 340 from clients using a reserved port#. Since both the FreeBSD and Linux 341 NFSv4 clients use reserved port#s by default, this should not affect 342 most NFSv4 mounts. 343 34420181219: 345 The XLP config has been removed. We can't support 64-bit atomics in this 346 kernel because it is running in 32-bit mode. XLP users must transition 347 to running a 64-bit kernel (XLP64 or XLPN32). 348 349 The mips GXEMUL support has been removed from FreeBSD. MALTA* + qemu is 350 the preferred emulator today and we don't need two different ones. 351 352 The old sibyte / swarm / Broadcom BCM1250 support has been 353 removed from the mips port. 354 35520181211: 356 Clang, llvm, lld, lldb, compiler-rt and libc++ have been upgraded to 357 7.0.1. Please see the 20141231 entry below for information about 358 prerequisites and upgrading, if you are not already using clang 3.5.0 359 or higher. 360 36120181211: 362 Remove the timed and netdate programs from the base tree. Setting 363 the time with these daemons has been obsolete for over a decade. 364 36520181126: 366 On amd64, arm64 and armv7 (architectures that install LLVM's ld.lld 367 linker as /usr/bin/ld) GNU ld is no longer installed as ld.bfd, as 368 it produces broken binaries when ifuncs are in use. Users needing 369 GNU ld should install the binutils port or package. 370 37120181123: 372 The BSD crtbegin and crtend code has been enabled by default. It has 373 had extensive testing on amd64, arm64, and i386. It can be disabled 374 by building a world with -DWITHOUT_BSD_CRTBEGIN. 375 37620181115: 377 The set of CTM commands (ctm, ctm_smail, ctm_rmail, ctm_dequeue) 378 has been converted to a port (misc/ctm) and will be removed from 379 FreeBSD-13. It is available as a package (ctm) for all supported 380 FreeBSD versions. 381 38220181110: 383 The default newsyslog.conf(5) file has been changed to only include 384 files in /etc/newsyslog.conf.d/ and /usr/local/etc/newsyslog.conf.d/ if 385 the filenames end in '.conf' and do not begin with a '.'. 386 387 You should check the configuration files in these two directories match 388 this naming convention. You can verify which configuration files are 389 being included using the command: 390 $ newsyslog -Nrv 391 39220181015: 393 Ports for the DRM modules have been simplified. Now, amd64 users should 394 just install the drm-kmod port. All others should install 395 drm-legacy-kmod. 396 397 Graphics hardware that's newer than about 2010 usually works with 398 drm-kmod. For hardware older than 2013, however, some users will need 399 to use drm-legacy-kmod if drm-kmod doesn't work for them. Hardware older 400 than 2008 usually only works in drm-legacy-kmod. The graphics team can 401 only commit to hardware made since 2013 due to the complexity of the 402 market and difficulty to test all the older cards effectively. If you 403 have hardware supported by drm-kmod, you are strongly encouraged to use 404 that as you will get better support. 405 406 Other than KPI chasing, drm-legacy-kmod will not be updated. As outlined 407 elsewhere, the drm and drm2 modules will be eliminated from the src base 408 soon (with a limited exception for arm). Please update to the package 409 asap and report any issues to x11@freebsd.org. 410 411 Generally, anybody using the drm*-kmod packages should add 412 WITHOUT_DRM_MODULE=t and WITHOUT_DRM2_MODULE=t to avoid nasty 413 cross-threading surprises, especially with automatic driver 414 loading from X11 startup. These will become the defaults in 13-current 415 shortly. 416 41720181012: 418 The ixlv(4) driver has been renamed to iavf(4). As a consequence, 419 custom kernel and module loading configuration files must be updated 420 accordingly. Moreover, interfaces previous presented as ixlvN to the 421 system are now exposed as iavfN and network configuration files must 422 be adjusted as necessary. 423 42420181009: 425 OpenSSL has been updated to version 1.1.1. This update included 426 additional various API changes throughout the base system. It is 427 important to rebuild third-party software after upgrading. The value 428 of __FreeBSD_version has been bumped accordingly. 429 43020181006: 431 The legacy DRM modules and drivers have now been added to the loader's 432 module blacklist, in favor of loading them with kld_list in rc.conf(5). 433 The module blacklist may be overridden with the loader.conf(5) 434 'module_blacklist' variable, but loading them via rc.conf(5) is strongly 435 encouraged. 436 43720181002: 438 The cam(4) based nda(4) driver will be used over nvd(4) by default on 439 powerpc64. You may set 'options NVME_USE_NVD=1' in your kernel conf or 440 loader tunable 'hw.nvme.use_nvd=1' if you wish to use the existing 441 driver. Make sure to edit /boot/etc/kboot.conf and fstab to use the 442 nda device name. 443 44420180913: 445 Reproducible build mode is now on by default, in preparation for 446 FreeBSD 12.0. This eliminates build metadata such as the user, 447 host, and time from the kernel (and uname), unless the working tree 448 corresponds to a modified checkout from a version control system. 449 The previous behavior can be obtained by setting the /etc/src.conf 450 knob WITHOUT_REPRODUCIBLE_BUILD. 451 45220180826: 453 The Yarrow CSPRNG has been removed from the kernel as it has not been 454 supported by its designers since at least 2003. Fortuna has been the 455 default since FreeBSD-11. 456 45720180822: 458 devctl freeze/thaw have gone into the tree, the rc scripts have been 459 updated to use them and devmatch has been changed. You should update 460 kernel, userland and rc scripts all at the same time. 461 46220180818: 463 The default interpreter has been switched from 4th to Lua. 464 LOADER_DEFAULT_INTERP, documented in build(7), will override the default 465 interpreter. If you have custom FORTH code you will need to set 466 LOADER_DEFAULT_INTERP=4th (valid values are 4th, lua or simp) in 467 src.conf for the build. This will create default hard links between 468 loader and loader_4th instead of loader and loader_lua, the new default. 469 If you are using UEFI it will create the proper hard link to loader.efi. 470 471 bhyve uses userboot.so. It remains 4th-only until some issues are solved 472 regarding coexisting with multiple versions of FreeBSD are resolved. 473 47420180815: 475 ls(1) now respects the COLORTERM environment variable used in other 476 systems and software to indicate that a colored terminal is both 477 supported and desired. If ls(1) is suddenly emitting colors, they may 478 be disabled again by either removing the unwanted COLORTERM from your 479 environment, or using `ls --color=never`. The ls(1) specific CLICOLOR 480 may not be observed in a future release. 481 48220180808: 483 The default pager for most commands has been changed to "less". To 484 restore the old behavior, set PAGER="more" and MANPAGER="more -s" in 485 your environment. 486 48720180731: 488 The jedec_ts(4) driver has been removed. A superset of its functionality 489 is available in the jedec_dimm(4) driver, and the manpage for that 490 driver includes migration instructions. If you have "device jedec_ts" 491 in your kernel configuration file, it must be removed. 492 49320180730: 494 amd64/GENERIC now has EFI runtime services, EFIRT, enabled by default. 495 This should have no effect if the kernel is booted via BIOS/legacy boot. 496 EFIRT may be disabled via a loader tunable, efi.rt.disabled, if a system 497 has a buggy firmware that prevents a successful boot due to use of 498 runtime services. 499 50020180727: 501 Atmel AT91RM9200 and AT91SAM9, Cavium CNS 11xx and XScale 502 support has been removed from the tree. These ports were 503 obsolete and/or known to be broken for many years. 504 50520180723: 506 loader.efi has been augmented to participate more fully in the 507 UEFI boot manager protocol. loader.efi will now look at the 508 BootXXXX environment variable to determine if a specific kernel 509 or root partition was specified. XXXX is derived from BootCurrent. 510 efibootmgr(8) manages these standard UEFI variables. 511 51220180720: 513 zfsloader's functionality has now been folded into loader. 514 zfsloader is no longer necessary once you've updated your 515 boot blocks. For a transition period, we will install a 516 hardlink for zfsloader to loader to allow a smooth transition 517 until the boot blocks can be updated (hard link because old 518 zfs boot blocks don't understand symlinks). 519 52020180719: 521 ARM64 now have efifb support, if you want to have serial console 522 on your arm64 board when an screen is connected and the bootloader 523 setup a frame buffer for us to use, just add : 524 boot_serial=YES 525 boot_multicons=YES 526 in /boot/loader.conf 527 For Raspberry Pi 3 (RPI) users, this is needed even if you don't have 528 an screen connected as the firmware will setup a frame buffer are that 529 u-boot will expose as an EFI frame buffer. 530 53120180719: 532 New uid:gid added, ntpd:ntpd (123:123). Be sure to run mergemaster 533 or take steps to update /etc/passwd before doing installworld on 534 existing systems. Do not skip the "mergemaster -Fp" step before 535 installworld, as described in the update procedures near the bottom 536 of this document. Also, rc.d/ntpd now starts ntpd(8) as user ntpd 537 if the new mac_ntpd(4) policy is available, unless ntpd_flags or 538 the ntp config file contain options that change file/dir locations. 539 When such options (e.g., "statsdir" or "crypto") are used, ntpd can 540 still be run as non-root by setting ntpd_user=ntpd in rc.conf, after 541 taking steps to ensure that all required files/dirs are accessible 542 by the ntpd user. 543 54420180717: 545 Big endian arm support has been removed. 546 54720180711: 548 The static environment setup in kernel configs is no longer mutually 549 exclusive with the loader(8) environment by default. In order to 550 restore the previous default behavior of disabling the loader(8) 551 environment if a static environment is present, you must specify 552 loader_env.disabled=1 in the static environment. 553 55420180705: 555 The ABI of syscalls used by management tools like sockstat and 556 netstat has been broken to allow 32-bit binaries to work on 557 64-bit kernels without modification. These programs will need 558 to match the kernel in order to function. External programs may 559 require minor modifications to accommodate a change of type in 560 structures from pointers to 64-bit virtual addresses. 561 56220180702: 563 On i386 and amd64 atomics are now inlined. Out of tree modules using 564 atomics will need to be rebuilt. 565 56620180701: 567 The '%I' format in the kern.corefile sysctl limits the number of 568 core files that a process can generate to the number stored in the 569 debug.ncores sysctl. The '%I' format is replaced by the single digit 570 index. Previously, if all indexes were taken the kernel would overwrite 571 only a core file with the highest index in a filename. 572 Currently the system will create a new core file if there is a free 573 index or if all slots are taken it will overwrite the oldest one. 574 57520180630: 576 Clang, llvm, lld, lldb, compiler-rt and libc++ have been upgraded to 577 6.0.1. Please see the 20141231 entry below for information about 578 prerequisites and upgrading, if you are not already using clang 3.5.0 579 or higher. 580 58120180628: 582 r335753 introduced a new quoting method. However, etc/devd/devmatch.conf 583 needed to be changed to work with it. This change was made with r335763 584 and requires a mergemaster / etcupdate / etc to update the installed 585 file. 586 58720180612: 588 r334930 changed the interface between the NFS modules, so they all 589 need to be rebuilt. r335018 did a __FreeBSD_version bump for this. 590 59120180530: 592 As of r334391 lld is the default amd64 system linker; it is installed 593 as /usr/bin/ld. Kernel build workarounds (see 20180510 entry) are no 594 longer necessary. 595 59620180530: 597 The kernel / userland interface for devinfo changed, so you'll 598 need a new kernel and userland as a pair for it to work (rebuilding 599 lib/libdevinfo is all that's required). devinfo and devmatch will 600 not work, but everything else will when there's a mismatch. 601 60220180523: 603 The on-disk format for hwpmc callchain records has changed to include 604 threadid corresponding to a given record. This changes the field offsets 605 and thus requires that libpmcstat be rebuilt before using a kernel 606 later than r334108. 607 60820180517: 609 The vxge(4) driver has been removed. This driver was introduced into 610 HEAD one week before the Exar left the Ethernet market and is not 611 known to be used. If you have device vxge in your kernel config file 612 it must be removed. 613 61420180510: 615 The amd64 kernel now requires a ld that supports ifunc to produce a 616 working kernel, either lld or a newer binutils. lld is built by default 617 on amd64, and the 'buildkernel' target uses it automatically. However, 618 it is not the default linker, so building the kernel the traditional 619 way requires LD=ld.lld on the command line (or LD=/usr/local/bin/ld for 620 binutils port/package). lld will soon be default, and this requirement 621 will go away. 622 623 NOTE: As of r334391 lld is the default system linker on amd64, and no 624 workaround is necessary. 625 62620180508: 627 The nxge(4) driver has been removed. This driver was for PCI-X 10g 628 cards made by s2io/Neterion. The company was acquired by Exar and 629 no longer sells or supports Ethernet products. If you have device 630 nxge in your kernel config file it must be removed. 631 63220180504: 633 The tz database (tzdb) has been updated to 2018e. This version more 634 correctly models time stamps in time zones with negative DST such as 635 Europe/Dublin (from 1971 on), Europe/Prague (1946/7), and 636 Africa/Windhoek (1994/2017). This does not affect the UT offsets, only 637 time zone abbreviations and the tm_isdst flag. 638 63920180502: 640 The ixgb(4) driver has been removed. This driver was for an early and 641 uncommon legacy PCI 10GbE for a single ASIC, Intel 82597EX. Intel 642 quickly shifted to the long lived ixgbe family. If you have device 643 ixgb in your kernel config file it must be removed. 644 64520180501: 646 The lmc(4) driver has been removed. This was a WAN interface 647 card that was already reportedly rare in 2003, and had an ambiguous 648 license. If you have device lmc in your kernel config file it must 649 be removed. 650 65120180413: 652 Support for Arcnet networks has been removed. If you have device 653 arcnet or device cm in your kernel config file they must be 654 removed. 655 65620180411: 657 Support for FDDI networks has been removed. If you have device 658 fddi or device fpa in your kernel config file they must be 659 removed. 660 66120180406: 662 In addition to supporting RFC 3164 formatted messages, the 663 syslogd(8) service is now capable of parsing RFC 5424 formatted 664 log messages. The main benefit of using RFC 5424 is that clients 665 may now send log messages with timestamps containing year numbers, 666 microseconds and time zone offsets. 667 668 Similarly, the syslog(3) C library function has been altered to 669 send RFC 5424 formatted messages to the local system logging 670 daemon. On systems using syslogd(8), this change should have no 671 negative impact, as long as syslogd(8) and the C library are 672 updated at the same time. On systems using a different system 673 logging daemon, it may be necessary to make configuration 674 adjustments, depending on the software used. 675 676 When using syslog-ng, add the 'syslog-protocol' flag to local 677 input sources to enable parsing of RFC 5424 formatted messages: 678 679 source src { 680 unix-dgram("/var/run/log" flags(syslog-protocol)); 681 } 682 683 When using rsyslog, disable the 'SysSock.UseSpecialParser' option 684 of the 'imuxsock' module to let messages be processed by the 685 regular RFC 3164/5424 parsing pipeline: 686 687 module(load="imuxsock" SysSock.UseSpecialParser="off") 688 689 Do note that these changes only affect communication between local 690 applications and syslogd(8). The format that syslogd(8) uses to 691 store messages on disk or forward messages to other systems 692 remains unchanged. syslogd(8) still uses RFC 3164 for these 693 purposes. Options to customize this behaviour will be added in the 694 future. Utilities that process log files stored in /var/log are 695 thus expected to continue to function as before. 696 697 __FreeBSD_version has been incremented to 1200061 to denote this 698 change. 699 70020180328: 701 Support for token ring networks has been removed. If you 702 have "device token" in your kernel config you should remove 703 it. No device drivers supported token ring. 704 70520180323: 706 makefs was modified to be able to tag ISO9660 El Torito boot catalog 707 entries as EFI instead of overloading the i386 tag as done previously. 708 The amd64 mkisoimages.sh script used to build amd64 ISO images for 709 release was updated to use this. This may mean that makefs must be 710 updated before "make cdrom" can be run in the release directory. This 711 should be as simple as: 712 713 $ cd $SRCDIR/usr.sbin/makefs 714 $ make depend all install 715 71620180212: 717 FreeBSD boot loader enhanced with Lua scripting. It's purely opt-in for 718 now by building WITH_LOADER_LUA and WITHOUT_FORTH in /etc/src.conf. 719 Co-existence for the transition period will come shortly. Booting is a 720 complex environment and test coverage for Lua-enabled loaders has been 721 thin, so it would be prudent to assume it might not work and make 722 provisions for backup boot methods. 723 72420180211: 725 devmatch functionality has been turned on in devd. It will automatically 726 load drivers for unattached devices. This may cause unexpected drivers 727 to be loaded. Please report any problems to current@ and 728 imp@freebsd.org. 729 73020180114: 731 Clang, llvm, lld, lldb, compiler-rt and libc++ have been upgraded to 732 6.0.0. Please see the 20141231 entry below for information about 733 prerequisites and upgrading, if you are not already using clang 3.5.0 734 or higher. 735 73620180110: 737 LLVM's lld linker is now used as the FreeBSD/amd64 bootstrap linker. 738 This means it is used to link the kernel and userland libraries and 739 executables, but is not yet installed as /usr/bin/ld by default. 740 741 To revert to ld.bfd as the bootstrap linker, in /etc/src.conf set 742 WITHOUT_LLD_BOOTSTRAP=yes 743 74420180110: 745 On i386, pmtimer has been removed. Its functionality has been folded 746 into apm. It was a no-op on ACPI in current for a while now (but was 747 still needed on i386 in FreeBSD 11 and earlier). Users may need to 748 remove it from kernel config files. 749 75020180104: 751 The use of RSS hash from the network card aka flowid has been 752 disabled by default for lagg(4) as it's currently incompatible with 753 the lacp and loadbalance protocols. 754 755 This can be re-enabled by setting the following in loader.conf: 756 net.link.lagg.default_use_flowid="1" 757 75820180102: 759 The SW_WATCHDOG option is no longer necessary to enable the 760 hardclock-based software watchdog if no hardware watchdog is 761 configured. As before, SW_WATCHDOG will cause the software 762 watchdog to be enabled even if a hardware watchdog is configured. 763 76420171215: 765 r326887 fixes the issue described in the 20171214 UPDATING entry. 766 r326888 flips the switch back to building GELI support always. 767 76820171214: 769 r362593 broke ZFS + GELI support for reasons unknown. However, 770 it also broke ZFS support generally, so GELI has been turned off 771 by default as the lesser evil in r326857. If you boot off ZFS and/or 772 GELI, it might not be a good time to update. 773 77420171125: 775 PowerPC users must update loader(8) by rebuilding world before 776 installing a new kernel, as the protocol connecting them has 777 changed. Without the update, loader metadata will not be passed 778 successfully to the kernel and users will have to enter their 779 root partition at the kernel mountroot prompt to continue booting. 780 Newer versions of loader can boot old kernels without issue. 781 78220171110: 783 The LOADER_FIREWIRE_SUPPORT build variable as been renamed to 784 WITH/OUT_LOADER_FIREWIRE. LOADER_{NO_,}GELI_SUPPORT has been renamed 785 to WITH/OUT_LOADER_GELI. 786 78720171106: 788 The naive and non-compliant support of posix_fallocate(2) in ZFS 789 has been removed as of r325320. The system call now returns EINVAL 790 when used on a ZFS file. Although the new behavior complies with the 791 standard, some consumers are not prepared to cope with it. 792 One known victim is lld prior to r325420. 793 79420171102: 795 Building in a FreeBSD src checkout will automatically create object 796 directories now rather than store files in the current directory if 797 'make obj' was not ran. Calling 'make obj' is no longer necessary. 798 This feature can be disabled by setting WITHOUT_AUTO_OBJ=yes in 799 /etc/src-env.conf (not /etc/src.conf), or passing the option in the 800 environment. 801 80220171101: 803 The default MAKEOBJDIR has changed from /usr/obj/<srcdir> for native 804 builds, and /usr/obj/<arch>/<srcdir> for cross-builds, to a unified 805 /usr/obj/<srcdir>/<arch>. This behavior can be changed to the old 806 format by setting WITHOUT_UNIFIED_OBJDIR=yes in /etc/src-env.conf, 807 the environment, or with -DWITHOUT_UNIFIED_OBJDIR when building. 808 The UNIFIED_OBJDIR option is a transitional feature that will be 809 removed for 12.0 release; please migrate to the new format for any 810 tools by looking up the OBJDIR used by 'make -V .OBJDIR' means rather 811 than hardcoding paths. 812 81320171028: 814 The native-xtools target no longer installs the files by default to the 815 OBJDIR. Use the native-xtools-install target with a DESTDIR to install 816 to ${DESTDIR}/${NXTP} where NXTP defaults to /nxb-bin. 817 81820171021: 819 As part of the boot loader infrastructure cleanup, LOADER_*_SUPPORT 820 options are changing from controlling the build if defined / undefined 821 to controlling the build with explicit 'yes' or 'no' values. They will 822 shift to WITH/WITHOUT options to match other options in the system. 823 82420171010: 825 libstand has turned into a private library for sys/boot use only. 826 It is no longer supported as a public interface outside of sys/boot. 827 82820171005: 829 The arm port has split armv6 into armv6 and armv7. armv7 is now 830 a valid TARGET_ARCH/MACHINE_ARCH setting. If you have an armv7 system 831 and are running a kernel from before r324363, you will need to add 832 MACHINE_ARCH=armv7 to 'make buildworld' to do a native build. 833 83420171003: 835 When building multiple kernels using KERNCONF, non-existent KERNCONF 836 files will produce an error and buildkernel will fail. Previously 837 missing KERNCONF files silently failed giving no indication as to 838 why, only to subsequently discover during installkernel that the 839 desired kernel was never built in the first place. 840 84120170912: 842 The default serial number format for CTL LUNs has changed. This will 843 affect users who use /dev/diskid/* device nodes, or whose FibreChannel 844 or iSCSI clients care about their LUNs' serial numbers. Users who 845 require serial number stability should hardcode serial numbers in 846 /etc/ctl.conf . 847 84820170912: 849 For 32-bit arm compiled for hard-float support, soft-floating point 850 binaries now always get their shared libraries from 851 LD_SOFT_LIBRARY_PATH (in the past, this was only used if 852 /usr/libsoft also existed). Only users with a hard-float ld.so, but 853 soft-float everything else should be affected. 854 85520170826: 856 The geli password typed at boot is now hidden. To restore the previous 857 behavior, see geli(8) for configuration options. 858 85920170825: 860 Move PMTUD blackhole counters to TCPSTATS and remove them from bare 861 sysctl values. Minor nit, but requires a rebuild of both world/kernel 862 to complete. 863 86420170814: 865 "make check" behavior (made in ^/head@r295380) has been changed to 866 execute from a limited sandbox, as opposed to executing from 867 ${TESTSDIR}. 868 869 Behavioral changes: 870 - The "beforecheck" and "aftercheck" targets are now specified. 871 - ${CHECKDIR} (added in commit noted above) has been removed. 872 - Legacy behavior can be enabled by setting 873 WITHOUT_MAKE_CHECK_USE_SANDBOX in src.conf(5) or the environment. 874 875 If the limited sandbox mode is enabled, "make check" will execute 876 "make distribution", then install, execute the tests, and clean up the 877 sandbox if successful. 878 879 The "make distribution" and "make install" targets are typically run as 880 root to set appropriate permissions and ownership at installation time. 881 The end-user should set "WITH_INSTALL_AS_USER" in src.conf(5) or the 882 environment if executing "make check" with limited sandbox mode using 883 an unprivileged user. 884 88520170808: 886 Since the switch to GPT disk labels, fsck for UFS/FFS has been 887 unable to automatically find alternate superblocks. As of r322297, 888 the information needed to find alternate superblocks has been 889 moved to the end of the area reserved for the boot block. 890 Filesystems created with a newfs of this vintage or later 891 will create the recovery information. If you have a filesystem 892 created prior to this change and wish to have a recovery block 893 created for your filesystem, you can do so by running fsck in 894 foreground mode (i.e., do not use the -p or -y options). As it 895 starts, fsck will ask ``SAVE DATA TO FIND ALTERNATE SUPERBLOCKS'' 896 to which you should answer yes. 897 89820170728: 899 As of r321665, an NFSv4 server configuration that services 900 Kerberos mounts or clients that do not support the uid/gid in 901 owner/owner_group string capability, must explicitly enable 902 the nfsuserd daemon by adding nfsuserd_enable="YES" to the 903 machine's /etc/rc.conf file. 904 90520170722: 906 Clang, llvm, lldb, compiler-rt and libc++ have been upgraded to 5.0.0. 907 Please see the 20141231 entry below for information about prerequisites 908 and upgrading, if you are not already using clang 3.5.0 or higher. 909 91020170701: 911 WITHOUT_RCMDS is now the default. Set WITH_RCMDS if you need the 912 r-commands (rlogin, rsh, etc.) to be built with the base system. 913 91420170625: 915 The FreeBSD/powerpc platform now uses a 64-bit type for time_t. This is 916 a very major ABI incompatible change, so users of FreeBSD/powerpc must 917 be careful when performing source upgrades. It is best to run 918 'make installworld' from an alternate root system, either a live 919 CD/memory stick, or a temporary root partition. Additionally, all ports 920 must be recompiled. powerpc64 is largely unaffected, except in the case 921 of 32-bit compatibility. All 32-bit binaries will be affected. 922 92320170623: 924 Forward compatibility for the "ino64" project have been committed. This 925 will allow most new binaries to run on older kernels in a limited 926 fashion. This prevents many of the common foot-shooting actions in the 927 upgrade as well as the limited ability to roll back the kernel across 928 the ino64 upgrade. Complicated use cases may not work properly, though 929 enough simpler ones work to allow recovery in most situations. 930 93120170620: 932 Switch back to the BSDL dtc (Device Tree Compiler). Set WITH_GPL_DTC 933 if you require the GPL compiler. 934 93520170618: 936 The internal ABI used for communication between the NFS kernel modules 937 was changed by r320085, so __FreeBSD_version was bumped to 938 ensure all the NFS related modules are updated together. 939 94020170617: 941 The ABI of struct event was changed by extending the data 942 member to 64bit and adding ext fields. For upgrade, same 943 precautions as for the entry 20170523 "ino64" must be 944 followed. 945 94620170531: 947 The GNU roff toolchain has been removed from base. To render manpages 948 which are not supported by mandoc(1), man(1) can fallback on GNU roff 949 from ports (and recommends to install it). 950 To render roff(7) documents, consider using GNU roff from ports or the 951 heirloom doctools roff toolchain from ports via pkg install groff or 952 via pkg install heirloom-doctools. 953 95420170524: 955 The ath(4) and ath_hal(4) modules now build piecemeal to allow for 956 smaller runtime footprint builds. This is useful for embedded systems 957 which only require one chipset support. 958 959 If you load it as a module, make sure this is in /boot/loader.conf: 960 961 if_ath_load="YES" 962 963 This will load the HAL, all chip/RF backends and if_ath_pci. 964 If you have if_ath_pci in /boot/loader.conf, ensure it is after 965 if_ath or it will not load any HAL chipset support. 966 967 If you want to selectively load things (eg on ye cheape ARM/MIPS 968 platforms where RAM is at a premium) you should: 969 970 * load ath_hal 971 * load the chip modules in question 972 * load ath_rate, ath_dfs 973 * load ath_main 974 * load if_ath_pci and/or if_ath_ahb depending upon your particular 975 bus bind type - this is where probe/attach is done. 976 977 For further comments/feedback, poke adrian@ . 978 97920170523: 980 The "ino64" 64-bit inode project has been committed, which extends 981 a number of types to 64 bits. Upgrading in place requires care and 982 adherence to the documented upgrade procedure. 983 984 If using a custom kernel configuration ensure that the 985 COMPAT_FREEBSD11 option is included (as during the upgrade the 986 system will be running the ino64 kernel with the existing world). 987 988 For the safest in-place upgrade begin by removing previous build 989 artifacts via "rm -rf /usr/obj/*". Then, carefully follow the full 990 procedure documented below under the heading "To rebuild everything and 991 install it on the current system." Specifically, a reboot is required 992 after installing the new kernel before installing world. While an 993 installworld normally works by accident from multiuser after rebooting 994 the proper kernel, there are many cases where this will fail across this 995 upgrade and installworld from single user is required. 996 99720170424: 998 The NATM framework including the en(4), fatm(4), hatm(4), and 999 patm(4) devices has been removed. Consumers should plan a 1000 migration before the end-of-life date for FreeBSD 11. 1001 100220170420: 1003 GNU diff has been replaced by a BSD licensed diff. Some features of GNU 1004 diff has not been implemented, if those are needed a newer version of 1005 GNU diff is available via the diffutils package under the gdiff name. 1006 100720170413: 1008 As of r316810 for ipfilter, keep frags is no longer assumed when 1009 keep state is specified in a rule. r316810 aligns ipfilter with 1010 documentation in man pages separating keep frags from keep state. 1011 This allows keep state to be specified without forcing keep frags 1012 and allows keep frags to be specified independently of keep state. 1013 To maintain previous behaviour, also specify keep frags with 1014 keep state (as documented in ipf.conf.5). 1015 101620170407: 1017 arm64 builds now use the base system LLD 4.0.0 linker by default, 1018 instead of requiring that the aarch64-binutils port or package be 1019 installed. To continue using aarch64-binutils, set 1020 CROSS_BINUTILS_PREFIX=/usr/local/aarch64-freebsd/bin . 1021 102220170405: 1023 The UDP optimization in entry 20160818 that added the sysctl 1024 net.inet.udp.require_l2_bcast has been reverted. L2 broadcast 1025 packets will no longer be treated as L3 broadcast packets. 1026 102720170331: 1028 Binds and sends to the loopback addresses, IPv6 and IPv4, will now 1029 use any explicitly assigned loopback address available in the jail 1030 instead of using the first assigned address of the jail. 1031 103220170329: 1033 The ctl.ko module no longer implements the iSCSI target frontend: 1034 cfiscsi.ko does instead. 1035 1036 If building cfiscsi.ko as a kernel module, the module can be loaded 1037 via one of the following methods: 1038 - `cfiscsi_load="YES"` in loader.conf(5). 1039 - Add `cfiscsi` to `$kld_list` in rc.conf(5). 1040 - ctladm(8)/ctld(8), when compiled with iSCSI support 1041 (`WITH_ISCSI=yes` in src.conf(5)) 1042 1043 Please see cfiscsi(4) for more details. 1044 104520170316: 1046 The mmcsd.ko module now additionally depends on geom_flashmap.ko. 1047 Also, mmc.ko and mmcsd.ko need to be a matching pair built from the 1048 same source (previously, the dependency of mmcsd.ko on mmc.ko was 1049 missing, but mmcsd.ko now will refuse to load if it is incompatible 1050 with mmc.ko). 1051 105220170315: 1053 The syntax of ipfw(8) named states was changed to avoid ambiguity. 1054 If you have used named states in the firewall rules, you need to modify 1055 them after installworld and before rebooting. Now named states must 1056 be prefixed with colon. 1057 105820170311: 1059 The old drm (sys/dev/drm/) drivers for i915 and radeon have been 1060 removed as the userland we provide cannot use them. The KMS version 1061 (sys/dev/drm2) supports the same hardware. 1062 106320170302: 1064 Clang, llvm, lldb, compiler-rt and libc++ have been upgraded to 4.0.0. 1065 Please see the 20141231 entry below for information about prerequisites 1066 and upgrading, if you are not already using clang 3.5.0 or higher. 1067 106820170221: 1069 The code that provides support for ZFS .zfs/ directory functionality 1070 has been reimplemented. It's not possible now to create a snapshot 1071 by mkdir under .zfs/snapshot/. That should be the only user visible 1072 change. 1073 107420170216: 1075 EISA bus support has been removed. The WITH_EISA option is no longer 1076 valid. 1077 107820170215: 1079 MCA bus support has been removed. 1080 108120170127: 1082 The WITH_LLD_AS_LD / WITHOUT_LLD_AS_LD build knobs have been renamed 1083 WITH_LLD_IS_LD / WITHOUT_LLD_IS_LD, for consistency with CLANG_IS_CC. 1084 108520170112: 1086 The EM_MULTIQUEUE kernel configuration option is deprecated now that 1087 the em(4) driver conforms to iflib specifications. 1088 108920170109: 1090 The igb(4), em(4) and lem(4) ethernet drivers are now implemented via 1091 IFLIB. If you have a custom kernel configuration that excludes em(4) 1092 but you use igb(4), you need to re-add em(4) to your custom 1093 configuration. 1094 109520161217: 1096 Clang, llvm, lldb, compiler-rt and libc++ have been upgraded to 3.9.1. 1097 Please see the 20141231 entry below for information about prerequisites 1098 and upgrading, if you are not already using clang 3.5.0 or higher. 1099 110020161124: 1101 Clang, llvm, lldb, compiler-rt and libc++ have been upgraded to 3.9.0. 1102 Please see the 20141231 entry below for information about prerequisites 1103 and upgrading, if you are not already using clang 3.5.0 or higher. 1104 110520161119: 1106 The layout of the pmap structure has changed for powerpc to put the pmap 1107 statistics at the front for all CPU variations. libkvm(3) and all tools 1108 that link against it need to be recompiled. 1109 111020161030: 1111 isl(4) and cyapa(4) drivers now require a new driver, 1112 chromebook_platform(4), to work properly on Chromebook-class hardware. 1113 On other types of hardware the drivers may need to be configured using 1114 device hints. Please see the corresponding manual pages for details. 1115 111620161017: 1117 The urtwn(4) driver was merged into rtwn(4) and now consists of 1118 rtwn(4) main module + rtwn_usb(4) and rtwn_pci(4) bus-specific 1119 parts. 1120 Also, firmware for RTL8188CE was renamed due to possible name 1121 conflict (rtwnrtl8192cU(B) -> rtwnrtl8192cE(B)) 1122 112320161015: 1124 GNU rcs has been removed from base. It is available as packages: 1125 - rcs: Latest GPLv3 GNU rcs version. 1126 - rcs57: Copy of the latest version of GNU rcs (GPLv2) before it was 1127 removed from base. 1128 112920161008: 1130 Use of the cc_cdg, cc_chd, cc_hd, or cc_vegas congestion control 1131 modules now requires that the kernel configuration contain the 1132 TCP_HHOOK option. (This option is included in the GENERIC kernel.) 1133 113420161003: 1135 The WITHOUT_ELFCOPY_AS_OBJCOPY src.conf(5) knob has been retired. 1136 ELF Tool Chain's elfcopy is always installed as /usr/bin/objcopy. 1137 113820160924: 1139 Relocatable object files with the extension of .So have been renamed 1140 to use an extension of .pico instead. The purpose of this change is 1141 to avoid a name clash with shared libraries on case-insensitive file 1142 systems. On those file systems, foo.So is the same file as foo.so. 1143 114420160918: 1145 GNU rcs has been turned off by default. It can (temporarily) be built 1146 again by adding WITH_RCS knob in src.conf. 1147 Otherwise, GNU rcs is available from packages: 1148 - rcs: Latest GPLv3 GNU rcs version. 1149 - rcs57: Copy of the latest version of GNU rcs (GPLv2) from base. 1150 115120160918: 1152 The backup_uses_rcs functionality has been removed from rc.subr. 1153 115420160908: 1155 The queue(3) debugging macro, QUEUE_MACRO_DEBUG, has been split into 1156 two separate components, QUEUE_MACRO_DEBUG_TRACE and 1157 QUEUE_MACRO_DEBUG_TRASH. Define both for the original 1158 QUEUE_MACRO_DEBUG behavior. 1159 116020160824: 1161 r304787 changed some ioctl interfaces between the iSCSI userspace 1162 programs and the kernel. ctladm, ctld, iscsictl, and iscsid must be 1163 rebuilt to work with new kernels. __FreeBSD_version has been bumped 1164 to 1200005. 1165 116620160818: 1167 The UDP receive code has been updated to only treat incoming UDP 1168 packets that were addressed to an L2 broadcast address as L3 1169 broadcast packets. It is not expected that this will affect any 1170 standards-conforming UDP application. The new behaviour can be 1171 disabled by setting the sysctl net.inet.udp.require_l2_bcast to 1172 0. 1173 117420160818: 1175 Remove the openbsd_poll system call. 1176 __FreeBSD_version has been bumped because of this. 1177 117820160708: 1179 The stable/11 branch has been created from head@r302406. 1180 118120160622: 1182 The libc stub for the pipe(2) system call has been replaced with 1183 a wrapper that calls the pipe2(2) system call and the pipe(2) 1184 system call is now only implemented by the kernels that include 1185 "options COMPAT_FREEBSD10" in their config file (this is the 1186 default). Users should ensure that this option is enabled in 1187 their kernel or upgrade userspace to r302092 before upgrading their 1188 kernel. 1189 119020160527: 1191 CAM will now strip leading spaces from SCSI disks' serial numbers. 1192 This will affect users who create UFS filesystems on SCSI disks using 1193 those disk's diskid device nodes. For example, if /etc/fstab 1194 previously contained a line like 1195 "/dev/diskid/DISK-%20%20%20%20%20%20%20ABCDEFG0123456", you should 1196 change it to "/dev/diskid/DISK-ABCDEFG0123456". Users of geom 1197 transforms like gmirror may also be affected. ZFS users should 1198 generally be fine. 1199 120020160523: 1201 The bitstring(3) API has been updated with new functionality and 1202 improved performance. But it is binary-incompatible with the old API. 1203 Objects built with the new headers may not be linked against objects 1204 built with the old headers. 1205 120620160520: 1207 The brk and sbrk functions have been removed from libc on arm64. 1208 Binutils from ports has been updated to not link to these 1209 functions and should be updated to the latest version before 1210 installing a new libc. 1211 121220160517: 1213 The armv6 port now defaults to hard float ABI. Limited support 1214 for running both hardfloat and soft float on the same system 1215 is available using the libraries installed with -DWITH_LIBSOFT. 1216 This has only been tested as an upgrade path for installworld 1217 and packages may fail or need manual intervention to run. New 1218 packages will be needed. 1219 1220 To update an existing self-hosted armv6hf system, you must add 1221 TARGET_ARCH=armv6 on the make command line for both the build 1222 and the install steps. 1223 122420160510: 1225 Kernel modules compiled outside of a kernel build now default to 1226 installing to /boot/modules instead of /boot/kernel. Many kernel 1227 modules built this way (such as those in ports) already overrode 1228 KMODDIR explicitly to install into /boot/modules. However, 1229 manually building and installing a module from /sys/modules will 1230 now install to /boot/modules instead of /boot/kernel. 1231 123220160414: 1233 The CAM I/O scheduler has been committed to the kernel. There should be 1234 no user visible impact. This does enable NCQ Trim on ada SSDs. While the 1235 list of known rogues that claim support for this but actually corrupt 1236 data is believed to be complete, be on the lookout for data 1237 corruption. The known rogue list is believed to be complete: 1238 1239 o Crucial MX100, M550 drives with MU01 firmware. 1240 o Micron M510 and M550 drives with MU01 firmware. 1241 o Micron M500 prior to MU07 firmware 1242 o Samsung 830, 840, and 850 all firmwares 1243 o FCCT M500 all firmwares 1244 1245 Crucial has firmware http://www.crucial.com/usa/en/support-ssd-firmware 1246 with working NCQ TRIM. For Micron branded drives, see your sales rep for 1247 updated firmware. Black listed drives will work correctly because these 1248 drives work correctly so long as no NCQ TRIMs are sent to them. Given 1249 this list is the same as found in Linux, it's believed there are no 1250 other rogues in the market place. All other models from the above 1251 vendors work. 1252 1253 To be safe, if you are at all concerned, you can quirk each of your 1254 drives to prevent NCQ from being sent by setting: 1255 kern.cam.ada.X.quirks="0x2" 1256 in loader.conf. If the drive requires the 4k sector quirk, set the 1257 quirks entry to 0x3. 1258 125920160330: 1260 The FAST_DEPEND build option has been removed and its functionality is 1261 now the one true way. The old mkdep(1) style of 'make depend' has 1262 been removed. See 20160311 for further details. 1263 126420160317: 1265 Resource range types have grown from unsigned long to uintmax_t. All 1266 drivers, and anything using libdevinfo, need to be recompiled. 1267 126820160311: 1269 WITH_FAST_DEPEND is now enabled by default for in-tree and out-of-tree 1270 builds. It no longer runs mkdep(1) during 'make depend', and the 1271 'make depend' stage can safely be skipped now as it is auto ran 1272 when building 'make all' and will generate all SRCS and DPSRCS before 1273 building anything else. Dependencies are gathered at compile time with 1274 -MF flags kept in separate .depend files per object file. Users should 1275 run 'make cleandepend' once if using -DNO_CLEAN to clean out older 1276 stale .depend files. 1277 127820160306: 1279 On amd64, clang 3.8.0 can now insert sections of type AMD64_UNWIND into 1280 kernel modules. Therefore, if you load any kernel modules at boot time, 1281 please install the boot loaders after you install the kernel, but before 1282 rebooting, e.g.: 1283 1284 make buildworld 1285 make buildkernel KERNCONF=YOUR_KERNEL_HERE 1286 make installkernel KERNCONF=YOUR_KERNEL_HERE 1287 make -C sys/boot install 1288 <reboot in single user> 1289 1290 Then follow the usual steps, described in the General Notes section, 1291 below. 1292 129320160305: 1294 Clang, llvm, lldb and compiler-rt have been upgraded to 3.8.0. Please 1295 see the 20141231 entry below for information about prerequisites and 1296 upgrading, if you are not already using clang 3.5.0 or higher. 1297 129820160301: 1299 The AIO subsystem is now a standard part of the kernel. The 1300 VFS_AIO kernel option and aio.ko kernel module have been removed. 1301 Due to stability concerns, asynchronous I/O requests are only 1302 permitted on sockets and raw disks by default. To enable 1303 asynchronous I/O requests on all file types, set the 1304 vfs.aio.enable_unsafe sysctl to a non-zero value. 1305 130620160226: 1307 The ELF object manipulation tool objcopy is now provided by the 1308 ELF Tool Chain project rather than by GNU binutils. It should be a 1309 drop-in replacement, with the addition of arm64 support. The 1310 (temporary) src.conf knob WITHOUT_ELFCOPY_AS_OBJCOPY knob may be set 1311 to obtain the GNU version if necessary. 1312 131320160129: 1314 Building ZFS pools on top of zvols is prohibited by default. That 1315 feature has never worked safely; it's always been prone to deadlocks. 1316 Using a zvol as the backing store for a VM guest's virtual disk will 1317 still work, even if the guest is using ZFS. Legacy behavior can be 1318 restored by setting vfs.zfs.vol.recursive=1. 1319 132020160119: 1321 The NONE and HPN patches has been removed from OpenSSH. They are 1322 still available in the security/openssh-portable port. 1323 132420160113: 1325 With the addition of ypldap(8), a new _ypldap user is now required 1326 during installworld. "mergemaster -p" can be used to add the user 1327 prior to installworld, as documented in the handbook. 1328 132920151216: 1330 The tftp loader (pxeboot) now uses the option root-path directive. As a 1331 consequence it no longer looks for a pxeboot.4th file on the tftp 1332 server. Instead it uses the regular /boot infrastructure as with the 1333 other loaders. 1334 133520151211: 1336 The code to start recording plug and play data into the modules has 1337 been committed. While the old tools will properly build a new kernel, 1338 a number of warnings about "unknown metadata record 4" will be produced 1339 for an older kldxref. To avoid such warnings, make sure to rebuild 1340 the kernel toolchain (or world). Make sure that you have r292078 or 1341 later when trying to build 292077 or later before rebuilding. 1342 134320151207: 1344 Debug data files are now built by default with 'make buildworld' and 1345 installed with 'make installworld'. This facilitates debugging but 1346 requires more disk space both during the build and for the installed 1347 world. Debug files may be disabled by setting WITHOUT_DEBUG_FILES=yes 1348 in src.conf(5). 1349 135020151130: 1351 r291527 changed the internal interface between the nfsd.ko and 1352 nfscommon.ko modules. As such, they must both be upgraded to-gether. 1353 __FreeBSD_version has been bumped because of this. 1354 135520151108: 1356 Add support for unicode collation strings leads to a change of 1357 order of files listed by ls(1) for example. To get back to the old 1358 behaviour, set LC_COLLATE environment variable to "C". 1359 1360 Databases administrators will need to reindex their databases given 1361 collation results will be different. 1362 1363 Due to a bug in install(1) it is recommended to remove the ancient 1364 locales before running make installworld. 1365 1366 rm -rf /usr/share/locale/* 1367 136820151030: 1369 The OpenSSL has been upgraded to 1.0.2d. Any binaries requiring 1370 libcrypto.so.7 or libssl.so.7 must be recompiled. 1371 137220151020: 1373 Qlogic 24xx/25xx firmware images were updated from 5.5.0 to 7.3.0. 1374 Kernel modules isp_2400_multi and isp_2500_multi were removed and 1375 should be replaced with isp_2400 and isp_2500 modules respectively. 1376 137720151017: 1378 The build previously allowed using 'make -n' to not recurse into 1379 sub-directories while showing what commands would be executed, and 1380 'make -n -n' to recursively show commands. Now 'make -n' will recurse 1381 and 'make -N' will not. 1382 138320151012: 1384 If you specify SENDMAIL_MC or SENDMAIL_CF in make.conf, mergemaster 1385 and etcupdate will now use this file. A custom sendmail.cf is now 1386 updated via this mechanism rather than via installworld. If you had 1387 excluded sendmail.cf in mergemaster.rc or etcupdate.conf, you may 1388 want to remove the exclusion or change it to "always install". 1389 /etc/mail/sendmail.cf is now managed the same way regardless of 1390 whether SENDMAIL_MC/SENDMAIL_CF is used. If you are not using 1391 SENDMAIL_MC/SENDMAIL_CF there should be no change in behavior. 1392 139320151011: 1394 Compatibility shims for legacy ATA device names have been removed. 1395 It includes ATA_STATIC_ID kernel option, kern.cam.ada.legacy_aliases 1396 and kern.geom.raid.legacy_aliases loader tunables, kern.devalias.* 1397 environment variables, /dev/ad* and /dev/ar* symbolic links. 1398 139920151006: 1400 Clang, llvm, lldb, compiler-rt and libc++ have been upgraded to 3.7.0. 1401 Please see the 20141231 entry below for information about prerequisites 1402 and upgrading, if you are not already using clang 3.5.0 or higher. 1403 140420150924: 1405 Kernel debug files have been moved to /usr/lib/debug/boot/kernel/, 1406 and renamed from .symbols to .debug. This reduces the size requirements 1407 on the boot partition or file system and provides consistency with 1408 userland debug files. 1409 1410 When using the supported kernel installation method the 1411 /usr/lib/debug/boot/kernel directory will be renamed (to kernel.old) 1412 as is done with /boot/kernel. 1413 1414 Developers wishing to maintain the historical behavior of installing 1415 debug files in /boot/kernel/ can set KERN_DEBUGDIR="" in src.conf(5). 1416 141720150827: 1418 The wireless drivers had undergone changes that remove the 'parent 1419 interface' from the ifconfig -l output. The rc.d network scripts 1420 used to check presence of a parent interface in the list, so old 1421 scripts would fail to start wireless networking. Thus, etcupdate(3) 1422 or mergemaster(8) run is required after kernel update, to update your 1423 rc.d scripts in /etc. 1424 142520150827: 1426 pf no longer supports 'scrub fragment crop' or 'scrub fragment drop-ovl' 1427 These configurations are now automatically interpreted as 1428 'scrub fragment reassemble'. 1429 143020150817: 1431 Kernel-loadable modules for the random(4) device are back. To use 1432 them, the kernel must have 1433 1434 device random 1435 options RANDOM_LOADABLE 1436 1437 kldload(8) can then be used to load random_fortuna.ko 1438 or random_yarrow.ko. Please note that due to the indirect 1439 function calls that the loadable modules need to provide, 1440 the build-in variants will be slightly more efficient. 1441 1442 The random(4) kernel option RANDOM_DUMMY has been retired due to 1443 unpopularity. It was not all that useful anyway. 1444 144520150813: 1446 The WITHOUT_ELFTOOLCHAIN_TOOLS src.conf(5) knob has been retired. 1447 Control over building the ELF Tool Chain tools is now provided by 1448 the WITHOUT_TOOLCHAIN knob. 1449 145020150810: 1451 The polarity of Pulse Per Second (PPS) capture events with the 1452 uart(4) driver has been corrected. Prior to this change the PPS 1453 "assert" event corresponded to the trailing edge of a positive PPS 1454 pulse and the "clear" event was the leading edge of the next pulse. 1455 1456 As the width of a PPS pulse in a typical GPS receiver is on the 1457 order of 1 millisecond, most users will not notice any significant 1458 difference with this change. 1459 1460 Anyone who has compensated for the historical polarity reversal by 1461 configuring a negative offset equal to the pulse width will need to 1462 remove that workaround. 1463 146420150809: 1465 The default group assigned to /dev/dri entries has been changed 1466 from 'wheel' to 'video' with the id of '44'. If you want to have 1467 access to the dri devices please add yourself to the video group 1468 with: 1469 1470 # pw groupmod video -m $USER 1471 147220150806: 1473 The menu.rc and loader.rc files will now be replaced during 1474 upgrades. Please migrate local changes to menu.rc.local and 1475 loader.rc.local instead. 1476 147720150805: 1478 GNU Binutils versions of addr2line, c++filt, nm, readelf, size, 1479 strings and strip have been removed. The src.conf(5) knob 1480 WITHOUT_ELFTOOLCHAIN_TOOLS no longer provides the binutils tools. 1481 148220150728: 1483 As ZFS requires more kernel stack pages than is the default on some 1484 architectures e.g. i386, it now warns if KSTACK_PAGES is less than 1485 ZFS_MIN_KSTACK_PAGES (which is 4 at the time of writing). 1486 1487 Please consider using 'options KSTACK_PAGES=X' where X is greater 1488 than or equal to ZFS_MIN_KSTACK_PAGES i.e. 4 in such configurations. 1489 149020150706: 1491 sendmail has been updated to 8.15.2. Starting with FreeBSD 11.0 1492 and sendmail 8.15, sendmail uses uncompressed IPv6 addresses by 1493 default, i.e., they will not contain "::". For example, instead 1494 of ::1, it will be 0:0:0:0:0:0:0:1. This permits a zero subnet 1495 to have a more specific match, such as different map entries for 1496 IPv6:0:0 vs IPv6:0. This change requires that configuration 1497 data (including maps, files, classes, custom ruleset, etc.) must 1498 use the same format, so make certain such configuration data is 1499 upgrading. As a very simple check search for patterns like 1500 'IPv6:[0-9a-fA-F:]*::' and 'IPv6::'. To return to the old 1501 behavior, set the m4 option confUSE_COMPRESSED_IPV6_ADDRESSES or 1502 the cf option UseCompressedIPv6Addresses. 1503 150420150630: 1505 The default kernel entropy-processing algorithm is now 1506 Fortuna, replacing Yarrow. 1507 1508 Assuming you have 'device random' in your kernel config 1509 file, the configurations allow a kernel option to override 1510 this default. You may choose *ONE* of: 1511 1512 options RANDOM_YARROW # Legacy /dev/random algorithm. 1513 options RANDOM_DUMMY # Blocking-only driver. 1514 1515 If you have neither, you get Fortuna. For most people, 1516 read no further, Fortuna will give a /dev/random that works 1517 like it always used to, and the difference will be irrelevant. 1518 1519 If you remove 'device random', you get *NO* kernel-processed 1520 entropy at all. This may be acceptable to folks building 1521 embedded systems, but has complications. Carry on reading, 1522 and it is assumed you know what you need. 1523 1524 *PLEASE* read random(4) and random(9) if you are in the 1525 habit of tweaking kernel configs, and/or if you are a member 1526 of the embedded community, wanting specific and not-usual 1527 behaviour from your security subsystems. 1528 1529 NOTE!! If you use RANDOM_DUMMY and/or have no 'device 1530 random', you will NOT have a functioning /dev/random, and 1531 many cryptographic features will not work, including SSH. 1532 You may also find strange behaviour from the random(3) set 1533 of library functions, in particular sranddev(3), srandomdev(3) 1534 and arc4random(3). The reason for this is that the KERN_ARND 1535 sysctl only returns entropy if it thinks it has some to 1536 share, and with RANDOM_DUMMY or no 'device random' this 1537 will never happen. 1538 153920150623: 1540 An additional fix for the issue described in the 20150614 sendmail 1541 entry below has been committed in revision 284717. 1542 154320150616: 1544 FreeBSD's old make (fmake) has been removed from the system. It is 1545 available as the devel/fmake port or via pkg install fmake. 1546 154720150615: 1548 The fix for the issue described in the 20150614 sendmail entry 1549 below has been committed in revision 284436. The work 1550 around described in that entry is no longer needed unless the 1551 default setting is overridden by a confDH_PARAMETERS configuration 1552 setting of '5' or pointing to a 512 bit DH parameter file. 1553 155420150614: 1555 ALLOW_DEPRECATED_ATF_TOOLS/ATFFILE support has been removed from 1556 atf.test.mk (included from bsd.test.mk). Please upgrade devel/atf 1557 and devel/kyua to version 0.20+ and adjust any calling code to work 1558 with Kyuafile and kyua. 1559 156020150614: 1561 The import of openssl to address the FreeBSD-SA-15:10.openssl 1562 security advisory includes a change which rejects handshakes 1563 with DH parameters below 768 bits. sendmail releases prior 1564 to 8.15.2 (not yet released), defaulted to a 512 bit 1565 DH parameter setting for client connections. To work around 1566 this interoperability, sendmail can be configured to use a 1567 2048 bit DH parameter by: 1568 1569 1. Edit /etc/mail/`hostname`.mc 1570 2. If a setting for confDH_PARAMETERS does not exist or 1571 exists and is set to a string beginning with '5', 1572 replace it with '2'. 1573 3. If a setting for confDH_PARAMETERS exists and is set to 1574 a file path, create a new file with: 1575 openssl dhparam -out /path/to/file 2048 1576 4. Rebuild the .cf file: 1577 cd /etc/mail/; make; make install 1578 5. Restart sendmail: 1579 cd /etc/mail/; make restart 1580 1581 A sendmail patch is coming, at which time this file will be 1582 updated. 1583 158420150604: 1585 Generation of legacy formatted entries have been disabled by default 1586 in pwd_mkdb(8), as all base system consumers of the legacy formatted 1587 entries were converted to use the new format by default when the new, 1588 machine independent format have been added and supported since FreeBSD 1589 5.x. 1590 1591 Please see the pwd_mkdb(8) manual page for further details. 1592 159320150525: 1594 Clang and llvm have been upgraded to 3.6.1 release. Please see the 1595 20141231 entry below for information about prerequisites and upgrading, 1596 if you are not already using 3.5.0 or higher. 1597 159820150521: 1599 TI platform code switched to using vendor DTS files and this update 1600 may break existing systems running on Beaglebone, Beaglebone Black, 1601 and Pandaboard: 1602 1603 - dtb files should be regenerated/reinstalled. Filenames are the 1604 same but content is different now 1605 - GPIO addressing was changed, now each GPIO bank (32 pins per bank) 1606 has its own /dev/gpiocX device, e.g. pin 121 on /dev/gpioc0 in old 1607 addressing scheme is now pin 25 on /dev/gpioc3. 1608 - Pandaboard: /etc/ttys should be updated, serial console device is 1609 now /dev/ttyu2, not /dev/ttyu0 1610 161120150501: 1612 soelim(1) from gnu/usr.bin/groff has been replaced by usr.bin/soelim. 1613 If you need the GNU extension from groff soelim(1), install groff 1614 from package: pkg install groff, or via ports: textproc/groff. 1615 161620150423: 1617 chmod, chflags, chown and chgrp now affect symlinks in -R mode as 1618 defined in symlink(7); previously symlinks were silently ignored. 1619 162020150415: 1621 The const qualifier has been removed from iconv(3) to comply with 1622 POSIX. The ports tree is aware of this from r384038 onwards. 1623 162420150416: 1625 Libraries specified by LIBADD in Makefiles must have a corresponding 1626 DPADD_<lib> variable to ensure correct dependencies. This is now 1627 enforced in src.libnames.mk. 1628 162920150324: 1630 From legacy ata(4) driver was removed support for SATA controllers 1631 supported by more functional drivers ahci(4), siis(4) and mvs(4). 1632 Kernel modules ataahci and ataadaptec were removed completely, 1633 replaced by ahci and mvs modules respectively. 1634 163520150315: 1636 Clang, llvm and lldb have been upgraded to 3.6.0 release. Please see 1637 the 20141231 entry below for information about prerequisites and 1638 upgrading, if you are not already using 3.5.0 or higher. 1639 164020150307: 1641 The 32-bit PowerPC kernel has been changed to a position-independent 1642 executable. This can only be booted with a version of loader(8) 1643 newer than January 31, 2015, so make sure to update both world and 1644 kernel before rebooting. 1645 164620150217: 1647 If you are running a -CURRENT kernel since r273872 (Oct 30th, 2014), 1648 but before r278950, the RNG was not seeded properly. Immediately 1649 upgrade the kernel to r278950 or later and regenerate any keys (e.g. 1650 ssh keys or openssl keys) that were generated w/ a kernel from that 1651 range. This does not affect programs that directly used /dev/random 1652 or /dev/urandom. All userland uses of arc4random(3) are affected. 1653 165420150210: 1655 The autofs(4) ABI was changed in order to restore binary compatibility 1656 with 10.1-RELEASE. The automountd(8) daemon needs to be rebuilt to work 1657 with the new kernel. 1658 165920150131: 1660 The powerpc64 kernel has been changed to a position-independent 1661 executable. This can only be booted with a new version of loader(8), 1662 so make sure to update both world and kernel before rebooting. 1663 166420150118: 1665 Clang and llvm have been upgraded to 3.5.1 release. This is a bugfix 1666 only release, no new features have been added. Please see the 20141231 1667 entry below for information about prerequisites and upgrading, if you 1668 are not already using 3.5.0. 1669 167020150107: 1671 ELF tools addr2line, elfcopy (strip), nm, size, and strings are now 1672 taken from the ELF Tool Chain project rather than GNU binutils. They 1673 should be drop-in replacements, with the addition of arm64 support. 1674 The WITHOUT_ELFTOOLCHAIN_TOOLS= knob may be used to obtain the 1675 binutils tools, if necessary. See 20150805 for updated information. 1676 167720150105: 1678 The default Unbound configuration now enables remote control 1679 using a local socket. Users who have already enabled the 1680 local_unbound service should regenerate their configuration 1681 by running "service local_unbound setup" as root. 1682 168320150102: 1684 The GNU texinfo and GNU info pages have been removed. 1685 To be able to view GNU info pages please install texinfo from ports. 1686 168720141231: 1688 Clang, llvm and lldb have been upgraded to 3.5.0 release. 1689 1690 As of this release, a prerequisite for building clang, llvm and lldb is 1691 a C++11 capable compiler and C++11 standard library. This means that to 1692 be able to successfully build the cross-tools stage of buildworld, with 1693 clang as the bootstrap compiler, your system compiler or cross compiler 1694 should either be clang 3.3 or later, or gcc 4.8 or later, and your 1695 system C++ library should be libc++, or libdstdc++ from gcc 4.8 or 1696 later. 1697 1698 On any standard FreeBSD 10.x or 11.x installation, where clang and 1699 libc++ are on by default (that is, on x86 or arm), this should work out 1700 of the box. 1701 1702 On 9.x installations where clang is enabled by default, e.g. on x86 and 1703 powerpc, libc++ will not be enabled by default, so libc++ should be 1704 built (with clang) and installed first. If both clang and libc++ are 1705 missing, build clang first, then use it to build libc++. 1706 1707 On 8.x and earlier installations, upgrade to 9.x first, and then follow 1708 the instructions for 9.x above. 1709 1710 Sparc64 and mips users are unaffected, as they still use gcc 4.2.1 by 1711 default, and do not build clang. 1712 1713 Many embedded systems are resource constrained, and will not be able to 1714 build clang in a reasonable time, or in some cases at all. In those 1715 cases, cross building bootable systems on amd64 is a workaround. 1716 1717 This new version of clang introduces a number of new warnings, of which 1718 the following are most likely to appear: 1719 1720 -Wabsolute-value 1721 1722 This warns in two cases, for both C and C++: 1723 * When the code is trying to take the absolute value of an unsigned 1724 quantity, which is effectively a no-op, and almost never what was 1725 intended. The code should be fixed, if at all possible. If you are 1726 sure that the unsigned quantity can be safely cast to signed, without 1727 loss of information or undefined behavior, you can add an explicit 1728 cast, or disable the warning. 1729 1730 * When the code is trying to take an absolute value, but the called 1731 abs() variant is for the wrong type, which can lead to truncation. 1732 If you want to disable the warning instead of fixing the code, please 1733 make sure that truncation will not occur, or it might lead to unwanted 1734 side-effects. 1735 1736 -Wtautological-undefined-compare and 1737 -Wundefined-bool-conversion 1738 1739 These warn when C++ code is trying to compare 'this' against NULL, while 1740 'this' should never be NULL in well-defined C++ code. However, there is 1741 some legacy (pre C++11) code out there, which actively abuses this 1742 feature, which was less strictly defined in previous C++ versions. 1743 1744 Squid and openjdk do this, for example. The warning can be turned off 1745 for C++98 and earlier, but compiling the code in C++11 mode might result 1746 in unexpected behavior; for example, the parts of the program that are 1747 unreachable could be optimized away. 1748 174920141222: 1750 The old NFS client and server (kernel options NFSCLIENT, NFSSERVER) 1751 kernel sources have been removed. The .h files remain, since some 1752 utilities include them. This will need to be fixed later. 1753 If "mount -t oldnfs ..." is attempted, it will fail. 1754 If the "-o" option on mountd(8), nfsd(8) or nfsstat(1) is used, 1755 the utilities will report errors. 1756 175720141121: 1758 The handling of LOCAL_LIB_DIRS has been altered to skip addition of 1759 directories to top level SUBDIR variable when their parent 1760 directory is included in LOCAL_DIRS. Users with build systems with 1761 such hierarchies and without SUBDIR entries in the parent 1762 directory Makefiles should add them or add the directories to 1763 LOCAL_DIRS. 1764 176520141109: 1766 faith(4) and faithd(8) have been removed from the base system. Faith 1767 has been obsolete for a very long time. 1768 176920141104: 1770 vt(4), the new console driver, is enabled by default. It brings 1771 support for Unicode and double-width characters, as well as 1772 support for UEFI and integration with the KMS kernel video 1773 drivers. 1774 1775 You may need to update your console settings in /etc/rc.conf, 1776 most probably the keymap. During boot, /etc/rc.d/syscons will 1777 indicate what you need to do. 1778 1779 vt(4) still has issues and lacks some features compared to 1780 syscons(4). See the wiki for up-to-date information: 1781 https://wiki.freebsd.org/Newcons 1782 1783 If you want to keep using syscons(4), you can do so by adding 1784 the following line to /boot/loader.conf: 1785 kern.vty=sc 1786 178720141102: 1788 pjdfstest has been integrated into kyua as an opt-in test suite. 1789 Please see share/doc/pjdfstest/README for more details on how to 1790 execute it. 1791 179220141009: 1793 gperf has been removed from the base system for architectures 1794 that use clang. Ports that require gperf will obtain it from the 1795 devel/gperf port. 1796 179720140923: 1798 pjdfstest has been moved from tools/regression/pjdfstest to 1799 contrib/pjdfstest . 1800 180120140922: 1802 At svn r271982, The default linux compat kernel ABI has been adjusted 1803 to 2.6.18 in support of the linux-c6 compat ports infrastructure 1804 update. If you wish to continue using the linux-f10 compat ports, 1805 add compat.linux.osrelease=2.6.16 to your local sysctl.conf. Users are 1806 encouraged to update their linux-compat packages to linux-c6 during 1807 their next update cycle. 1808 180920140729: 1810 The ofwfb driver, used to provide a graphics console on PowerPC when 1811 using vt(4), no longer allows mmap() of all physical memory. This 1812 will prevent Xorg on PowerPC with some ATI graphics cards from 1813 initializing properly unless x11-servers/xorg-server is updated to 1814 1.12.4_8 or newer. 1815 181620140723: 1817 The xdev targets have been converted to using TARGET and 1818 TARGET_ARCH instead of XDEV and XDEV_ARCH. 1819 182020140719: 1821 The default unbound configuration has been modified to address 1822 issues with reverse lookups on networks that use private 1823 address ranges. If you use the local_unbound service, run 1824 "service local_unbound setup" as root to regenerate your 1825 configuration, then "service local_unbound reload" to load the 1826 new configuration. 1827 182820140709: 1829 The GNU texinfo and GNU info pages are not built and installed 1830 anymore, WITH_INFO knob has been added to allow to built and install 1831 them again. 1832 UPDATE: see 20150102 entry on texinfo's removal 1833 183420140708: 1835 The GNU readline library is now an INTERNALLIB - that is, it is 1836 statically linked into consumers (GDB and variants) in the base 1837 system, and the shared library is no longer installed. The 1838 devel/readline port is available for third party software that 1839 requires readline. 1840 184120140702: 1842 The Itanium architecture (ia64) has been removed from the list of 1843 known architectures. This is the first step in the removal of the 1844 architecture. 1845 184620140701: 1847 Commit r268115 has added NFSv4.1 server support, merged from 1848 projects/nfsv4.1-server. Since this includes changes to the 1849 internal interfaces between the NFS related modules, a full 1850 build of the kernel and modules will be necessary. 1851 __FreeBSD_version has been bumped. 1852 185320140629: 1854 The WITHOUT_VT_SUPPORT kernel config knob has been renamed 1855 WITHOUT_VT. (The other _SUPPORT knobs have a consistent meaning 1856 which differs from the behaviour controlled by this knob.) 1857 185820140619: 1859 Maximal length of the serial number in CTL was increased from 16 to 1860 64 chars, that breaks ABI. All CTL-related tools, such as ctladm 1861 and ctld, need to be rebuilt to work with a new kernel. 1862 186320140606: 1864 The libatf-c and libatf-c++ major versions were downgraded to 0 and 1865 1 respectively to match the upstream numbers. They were out of 1866 sync because, when they were originally added to FreeBSD, the 1867 upstream versions were not respected. These libraries are private 1868 and not yet built by default, so renumbering them should be a 1869 non-issue. However, unclean source trees will yield broken test 1870 programs once the operator executes "make delete-old-libs" after a 1871 "make installworld". 1872 1873 Additionally, the atf-sh binary was made private by moving it into 1874 /usr/libexec/. Already-built shell test programs will keep the 1875 path to the old binary so they will break after "make delete-old" 1876 is run. 1877 1878 If you are using WITH_TESTS=yes (not the default), wipe the object 1879 tree and rebuild from scratch to prevent spurious test failures. 1880 This is only needed once: the misnumbered libraries and misplaced 1881 binaries have been added to OptionalObsoleteFiles.inc so they will 1882 be removed during a clean upgrade. 1883 188420140512: 1885 Clang and llvm have been upgraded to 3.4.1 release. 1886 188720140508: 1888 We bogusly installed src.opts.mk in /usr/share/mk. This file should 1889 be removed to avoid issues in the future (and has been added to 1890 ObsoleteFiles.inc). 1891 189220140505: 1893 /etc/src.conf now affects only builds of the FreeBSD src tree. In the 1894 past, it affected all builds that used the bsd.*.mk files. The old 1895 behavior was a bug, but people may have relied upon it. To get this 1896 behavior back, you can .include /etc/src.conf from /etc/make.conf 1897 (which is still global and isn't changed). This also changes the 1898 behavior of incremental builds inside the tree of individual 1899 directories. Set MAKESYSPATH to ".../share/mk" to do that. 1900 Although this has survived make universe and some upgrade scenarios, 1901 other upgrade scenarios may have broken. At least one form of 1902 temporary breakage was fixed with MAKESYSPATH settings for buildworld 1903 as well... In cases where MAKESYSPATH isn't working with this 1904 setting, you'll need to set it to the full path to your tree. 1905 1906 One side effect of all this cleaning up is that bsd.compiler.mk 1907 is no longer implicitly included by bsd.own.mk. If you wish to 1908 use COMPILER_TYPE, you must now explicitly include bsd.compiler.mk 1909 as well. 1910 191120140430: 1912 The lindev device has been removed since /dev/full has been made a 1913 standard device. __FreeBSD_version has been bumped. 1914 191520140424: 1916 The knob WITHOUT_VI was added to the base system, which controls 1917 building ex(1), vi(1), etc. Older releases of FreeBSD required ex(1) 1918 in order to reorder files share/termcap and didn't build ex(1) as a 1919 build tool, so building/installing with WITH_VI is highly advised for 1920 build hosts for older releases. 1921 1922 This issue has been fixed in stable/9 and stable/10 in r277022 and 1923 r276991, respectively. 1924 192520140418: 1926 The YES_HESIOD knob has been removed. It has been obsolete for 1927 a decade. Please move to using WITH_HESIOD instead or your builds 1928 will silently lack HESIOD. 1929 193020140405: 1931 The uart(4) driver has been changed with respect to its handling 1932 of the low-level console. Previously the uart(4) driver prevented 1933 any process from changing the baudrate or the CLOCAL and HUPCL 1934 control flags. By removing the restrictions, operators can make 1935 changes to the serial console port without having to reboot. 1936 However, when getty(8) is started on the serial device that is 1937 associated with the low-level console, a misconfigured terminal 1938 line in /etc/ttys will now have a real impact. 1939 Before upgrading the kernel, make sure that /etc/ttys has the 1940 serial console device configured as 3wire without baudrate to 1941 preserve the previous behaviour. E.g: 1942 ttyu0 "/usr/libexec/getty 3wire" vt100 on secure 1943 194420140306: 1945 Support for libwrap (TCP wrappers) in rpcbind was disabled by default 1946 to improve performance. To re-enable it, if needed, run rpcbind 1947 with command line option -W. 1948 194920140226: 1950 Switched back to the GPL dtc compiler due to updates in the upstream 1951 dts files not being supported by the BSDL dtc compiler. You will need 1952 to rebuild your kernel toolchain to pick up the new compiler. Core dumps 1953 may result while building dtb files during a kernel build if you fail 1954 to do so. Set WITHOUT_GPL_DTC if you require the BSDL compiler. 1955 195620140216: 1957 Clang and llvm have been upgraded to 3.4 release. 1958 195920140216: 1960 The nve(4) driver has been removed. Please use the nfe(4) driver 1961 for NVIDIA nForce MCP Ethernet adapters instead. 1962 196320140212: 1964 An ABI incompatibility crept into the libc++ 3.4 import in r261283. 1965 This could cause certain C++ applications using shared libraries built 1966 against the previous version of libc++ to crash. The incompatibility 1967 has now been fixed, but any C++ applications or shared libraries built 1968 between r261283 and r261801 should be recompiled. 1969 197020140204: 1971 OpenSSH will now ignore errors caused by kernel lacking of Capsicum 1972 capability mode support. Please note that enabling the feature in 1973 kernel is still highly recommended. 1974 197520140131: 1976 OpenSSH is now built with sandbox support, and will use sandbox as 1977 the default privilege separation method. This requires Capsicum 1978 capability mode support in kernel. 1979 198020140128: 1981 The libelf and libdwarf libraries have been updated to newer 1982 versions from upstream. Shared library version numbers for 1983 these two libraries were bumped. Any ports or binaries 1984 requiring these two libraries should be recompiled. 1985 __FreeBSD_version is bumped to 1100006. 1986 198720140110: 1988 If a Makefile in a tests/ directory was auto-generating a Kyuafile 1989 instead of providing an explicit one, this would prevent such 1990 Makefile from providing its own Kyuafile in the future during 1991 NO_CLEAN builds. This has been fixed in the Makefiles but manual 1992 intervention is needed to clean an objdir if you use NO_CLEAN: 1993 # find /usr/obj -name Kyuafile | xargs rm -f 1994 199520131213: 1996 The behavior of gss_pseudo_random() for the krb5 mechanism 1997 has changed, for applications requesting a longer random string 1998 than produced by the underlying enctype's pseudo-random() function. 1999 In particular, the random string produced from a session key of 2000 enctype aes256-cts-hmac-sha1-96 or aes256-cts-hmac-sha1-96 will 2001 be different at the 17th octet and later, after this change. 2002 The counter used in the PRF+ construction is now encoded as a 2003 big-endian integer in accordance with RFC 4402. 2004 __FreeBSD_version is bumped to 1100004. 2005 200620131108: 2007 The WITHOUT_ATF build knob has been removed and its functionality 2008 has been subsumed into the more generic WITHOUT_TESTS. If you were 2009 using the former to disable the build of the ATF libraries, you 2010 should change your settings to use the latter. 2011 201220131025: 2013 The default version of mtree is nmtree which is obtained from 2014 NetBSD. The output is generally the same, but may vary 2015 slightly. If you found you need identical output adding 2016 "-F freebsd9" to the command line should do the trick. For the 2017 time being, the old mtree is available as fmtree. 2018 201920131014: 2020 libbsdyml has been renamed to libyaml and moved to /usr/lib/private. 2021 This will break ports-mgmt/pkg. Rebuild the port, or upgrade to pkg 2022 1.1.4_8 and verify bsdyml not linked in, before running "make 2023 delete-old-libs": 2024 # make -C /usr/ports/ports-mgmt/pkg build deinstall install clean 2025 or 2026 # pkg install pkg; ldd /usr/local/sbin/pkg | grep bsdyml 2027 202820131010: 2029 The stable/10 branch has been created in subversion from head 2030 revision r256279. 2031 2032COMMON ITEMS: 2033 2034 General Notes 2035 ------------- 2036 Sometimes, obscure build problems are the result of environment 2037 poisoning. This can happen because the make utility reads its 2038 environment when searching for values for global variables. To run 2039 your build attempts in an "environmental clean room", prefix all make 2040 commands with 'env -i '. See the env(1) manual page for more details. 2041 Occasionally a build failure will occur with "make -j" due to a race 2042 condition. If this happens try building again without -j, and please 2043 report a bug if it happens consistently. 2044 2045 When upgrading from one major version to another it is generally best to 2046 upgrade to the latest code in the currently installed branch first, then 2047 do an upgrade to the new branch. This is the best-tested upgrade path, 2048 and has the highest probability of being successful. Please try this 2049 approach if you encounter problems with a major version upgrade. Since 2050 the stable 4.x branch point, one has generally been able to upgrade from 2051 anywhere in the most recent stable branch to head / current (or even the 2052 last couple of stable branches). See the top of this file when there's 2053 an exception. 2054 2055 The update process will emit an error on an attempt to perform a build 2056 or install from a FreeBSD version below the earliest supported version. 2057 When updating from an older version the update should be performed one 2058 major release at a time, including running `make delete-old` at each 2059 step. 2060 2061 When upgrading a live system, having a root shell around before 2062 installing anything can help undo problems. Not having a root shell 2063 around can lead to problems if pam has changed too much from your 2064 starting point to allow continued authentication after the upgrade. 2065 2066 This file should be read as a log of events. When a later event changes 2067 information of a prior event, the prior event should not be deleted. 2068 Instead, a pointer to the entry with the new information should be 2069 placed in the old entry. Readers of this file should also sanity check 2070 older entries before relying on them blindly. Authors of new entries 2071 should write them with this in mind. 2072 2073 ZFS notes 2074 --------- 2075 When upgrading the boot ZFS pool to a new version, always follow 2076 these two steps: 2077 2078 1.) recompile and reinstall the ZFS boot loader and boot block 2079 (this is part of "make buildworld" and "make installworld") 2080 2081 2.) update the ZFS boot block on your boot drive 2082 2083 The following example updates the ZFS boot block on the first 2084 partition (freebsd-boot) of a GPT partitioned drive ada0: 2085 "gpart bootcode -p /boot/gptzfsboot -i 1 ada0" 2086 2087 Non-boot pools do not need these updates. 2088 2089 To build a kernel 2090 ----------------- 2091 If you are updating from a prior version of FreeBSD (even one just 2092 a few days old), you should follow this procedure. It is the most 2093 failsafe as it uses a /usr/obj tree with a fresh mini-buildworld, 2094 2095 make kernel-toolchain 2096 make -DALWAYS_CHECK_MAKE buildkernel KERNCONF=YOUR_KERNEL_HERE 2097 make -DALWAYS_CHECK_MAKE installkernel KERNCONF=YOUR_KERNEL_HERE 2098 2099 To test a kernel once 2100 --------------------- 2101 If you just want to boot a kernel once (because you are not sure 2102 if it works, or if you want to boot a known bad kernel to provide 2103 debugging information) run 2104 make installkernel KERNCONF=YOUR_KERNEL_HERE KODIR=/boot/testkernel 2105 nextboot -k testkernel 2106 2107 To rebuild everything and install it on the current system. 2108 ----------------------------------------------------------- 2109 # Note: sometimes if you are running current you gotta do more than 2110 # is listed here if you are upgrading from a really old current. 2111 2112 <make sure you have good level 0 dumps> 2113 make buildworld 2114 make buildkernel KERNCONF=YOUR_KERNEL_HERE 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 To cross-install current onto a separate partition 2125 -------------------------------------------------- 2126 # In this approach we use a separate partition to hold 2127 # current's root, 'usr', and 'var' directories. A partition 2128 # holding "/", "/usr" and "/var" should be about 2GB in 2129 # size. 2130 2131 <make sure you have good level 0 dumps> 2132 <boot into -stable> 2133 make buildworld 2134 make buildkernel KERNCONF=YOUR_KERNEL_HERE 2135 <maybe newfs current's root partition> 2136 <mount current's root partition on directory ${CURRENT_ROOT}> 2137 make installworld DESTDIR=${CURRENT_ROOT} -DDB_FROM_SRC 2138 make distribution DESTDIR=${CURRENT_ROOT} # if newfs'd 2139 make installkernel KERNCONF=YOUR_KERNEL_HERE DESTDIR=${CURRENT_ROOT} 2140 cp /etc/fstab ${CURRENT_ROOT}/etc/fstab # if newfs'd 2141 <edit ${CURRENT_ROOT}/etc/fstab to mount "/" from the correct partition> 2142 <reboot into current> 2143 <do a "native" rebuild/install as described in the previous section> 2144 <maybe install compatibility libraries from ports/misc/compat*> 2145 <reboot> 2146 2147 2148 To upgrade in-place from stable to current 2149 ---------------------------------------------- 2150 <make sure you have good level 0 dumps> 2151 make buildworld [9] 2152 make buildkernel KERNCONF=YOUR_KERNEL_HERE [8] 2153 make installkernel KERNCONF=YOUR_KERNEL_HERE 2154 [1] 2155 <reboot in single user> [3] 2156 mergemaster -Fp [5] 2157 make installworld 2158 mergemaster -Fi [4] 2159 make delete-old [6] 2160 <reboot> 2161 2162 Make sure that you've read the UPDATING file to understand the 2163 tweaks to various things you need. At this point in the life 2164 cycle of current, things change often and you are on your own 2165 to cope. The defaults can also change, so please read ALL of 2166 the UPDATING entries. 2167 2168 Also, if you are tracking -current, you must be subscribed to 2169 freebsd-current@freebsd.org. Make sure that before you update 2170 your sources that you have read and understood all the recent 2171 messages there. If in doubt, please track -stable which has 2172 much fewer pitfalls. 2173 2174 [1] If you have third party modules, such as vmware, you 2175 should disable them at this point so they don't crash your 2176 system on reboot. 2177 2178 [3] From the bootblocks, boot -s, and then do 2179 fsck -p 2180 mount -u / 2181 mount -a 2182 sh /etc/rc.d/zfs start # mount zfs filesystem, if needed 2183 cd src # full path to source 2184 adjkerntz -i # if CMOS is wall time 2185 Also, when doing a major release upgrade, it is required that 2186 you boot into single user mode to do the installworld. 2187 2188 [4] Note: This step is non-optional. Failure to do this step 2189 can result in a significant reduction in the functionality of the 2190 system. Attempting to do it by hand is not recommended and those 2191 that pursue this avenue should read this file carefully, as well 2192 as the archives of freebsd-current and freebsd-hackers mailing lists 2193 for potential gotchas. The -U option is also useful to consider. 2194 See mergemaster(8) for more information. 2195 2196 [5] Usually this step is a no-op. However, from time to time 2197 you may need to do this if you get unknown user in the following 2198 step. It never hurts to do it all the time. You may need to 2199 install a new mergemaster (cd src/usr.sbin/mergemaster && make 2200 install) after the buildworld before this step if you last updated 2201 from current before 20130425 or from -stable before 20130430. 2202 2203 [6] This only deletes old files and directories. Old libraries 2204 can be deleted by "make delete-old-libs", but you have to make 2205 sure that no program is using those libraries anymore. 2206 2207 [8] The new kernel must be able to run existing binaries used by an 2208 installworld. When upgrading across major versions, the new kernel's 2209 configuration must include the correct COMPAT_FREEBSD<n> option for 2210 existing binaries (e.g. COMPAT_FREEBSD11 to run 11.x binaries). Failure 2211 to do so may leave you with a system that is hard to boot to recover. A 2212 GENERIC kernel will include suitable compatibility options to run 2213 binaries from older branches. Note that the ability to run binaries 2214 from unsupported branches is not guaranteed. 2215 2216 Make sure that you merge any new devices from GENERIC since the 2217 last time you updated your kernel config file. Options also 2218 change over time, so you may need to adjust your custom kernels 2219 for these as well. 2220 2221 [9] If CPUTYPE is defined in your /etc/make.conf, make sure to use the 2222 "?=" instead of the "=" assignment operator, so that buildworld can 2223 override the CPUTYPE if it needs to. 2224 2225 MAKEOBJDIRPREFIX must be defined in an environment variable, and 2226 not on the command line, or in /etc/make.conf. buildworld will 2227 warn if it is improperly defined. 2228FORMAT: 2229 2230This file contains a list, in reverse chronological order, of major 2231breakages in tracking -current. It is not guaranteed to be a complete 2232list of such breakages, and only contains entries since September 23, 2011. 2233If you need to see UPDATING entries from before that date, you will need 2234to fetch an UPDATING file from an older FreeBSD release. 2235 2236Copyright information: 2237 2238Copyright 1998-2009 M.
