For commonly done items, please see the 5COMMON ITEMS: section later in the file. These instructions assume that you 6basically know what you are doing. If not, then please consult the FreeBSD 7handbook: 8 9 https://www.freebsd.org/doc/en_US.ISO8859-1/books/handbook/makeworld.html 10 11Items affecting the ports and packages system can be found in 12/usr/ports/UPDATING. Please read that file before running portupgrade. 13 14NOTE TO PEOPLE WHO THINK THAT FreeBSD 13.x IS SLOW: 15 FreeBSD 13.x has many debugging features turned on, in both the kernel 16 and userland. These features attempt to detect incorrect use of 17 system primitives, and encourage loud failure through extra sanity 18 checking and fail stop semantics. They also substantially impact 19 system performance. If you want to do performance measurement, 20 benchmarking, and optimization, you'll want to turn them off. This 21 includes various WITNESS- related kernel options, INVARIANTS, malloc 22 debugging flags in userland, and various verbose features in the 23 kernel. Many developers choose to disable these features on build 24 machines to maximize performance. (To completely disable malloc 25 debugging, define MALLOC_PRODUCTION in /etc/make.conf, or to merely 26 disable the most expensive debugging functionality run 27 "ln -s 'abort:false,junk:false' /etc/malloc.conf".) 28 2920191120: 30 The amd(8) automount daemon has been disabled by default, and will be 31 removed in the future. As of FreeBSD 10.1 the autofs(5) is available 32 for automounting. 33 3420191120: 35 Defining the long deprecated NO_CTF, NO_DEBUG_FILES, NO_INSTALLLIB, 36 NO_MAN, NO_PROFILE, and NO_WARNS variables is now an error. Update 37 your Makefiles and scripts to define MK_<var>=no instead as required. 38 39 One exception to this is that program or library Makefiles should 40 define MAN to empty rather than setting MK_MAN=no. 41 4220191107: 43 The nctgpio and wbwd drivers have been moved to the superio bus. 44 If you have one of these drivers in a kernel configuration, then 45 you should add device superio to it. If you use one of these drivers 46 as a module and you compile a custom set of modules, then you should 47 add superio to the set. 48 4920191021: 50 KPIs for network drivers to access interface addresses have changed. 51 Users need to recompile NIC driver modules together with kernel. 52 5320191021: 54 The net.link.tap.user_open sysctl no longer prevents user opening of 55 already created /dev/tapNN devices. Access is still controlled by 56 node permissions, just like tun devices. The net.link.tap.user_open 57 sysctl is now used only to allow users to perform devfs cloning of 58 tap devices, and the subsequent open may not succeed if the user is not 59 in the appropriate group. This sysctl may be deprecated/removed 60 completely in the future. 61 6220191009: 63 mips, powerpc, and sparc64 are no longer built as part of 64 universe / tinderbox unless MAKE_OBSOLETE_GCC is defined. If 65 not defined, mips, powerpc, and sparc64 builds will look for 66 the xtoolchain binaries and if installed use them for universe 67 builds. As llvm 9.0 becomes vetted for these architectures, they 68 will be removed from the list. 69 7020191009: 71 Clang, llvm, lld, lldb, compiler-rt, libc++, libunwind and openmp have 72 been upgraded to 9.0.0. Please see the 20141231 entry below for 73 information about prerequisites and upgrading, if you are not already 74 using clang 3.5.0 or higher. 75 7620191003: 77 The hpt27xx, hptmv, hptnr, and hptrr drivers have been removed from 78 GENERIC. They are available as modules and can be loaded by adding 79 to /boot/loader.conf hpt27xx_load="YES", hptmv_load="YES", 80 hptnr_load="YES", or hptrr_load="YES", respectively. 81 8220190913: 83 ntpd no longer by default locks its pages in memory, allowing them 84 to be paged out by the kernel. Use rlimit memlock to restore 85 historic BSD behaviour. For example, add "rlimit memlock 32" 86 to ntp.conf to lock up to 32 MB of ntpd address space in memory. 87 8820190823: 89 Several of ping6's options have been renamed for better consistency 90 with ping. If you use any of -ARWXaghmrtwx, you must update your 91 scripts. See ping6(8) for details. 92 9320190727: 94 The vfs.fusefs.sync_unmount and vfs.fusefs.init_backgrounded sysctls 95 and the "-o sync_unmount" and "-o init_backgrounded" mount options have 96 been removed from mount_fusefs(8). You can safely remove them from 97 your scripts, because they had no effect. 98 99 The vfs.fusefs.fix_broken_io, vfs.fusefs.sync_resize, 100 vfs.fusefs.refresh_size, vfs.fusefs.mmap_enable, 101 vfs.fusefs.reclaim_revoked, and vfs.fusefs.data_cache_invalidate 102 sysctls have been removed. If you felt the need to set any of them to 103 a non-default value, please tell asomers@FreeBSD.org why. 104 10520190713: 106 Default permissions on the /var/account/acct file (and copies of it 107 rotated by periodic daily scripts) are changed from 0644 to 0640 108 because the file contains sensitive information that should not be 109 world-readable. If the /var/account directory must be created by 110 rc.d/accounting, the mode used is now 0750. Admins who use the 111 accounting feature are encouraged to change the mode of an existing 112 /var/account directory to 0750 or 0700. 113 11420190620: 115 Entropy collection and the /dev/random device are no longer optional 116 components. The "device random" option has been removed. 117 Implementations of distilling algorithms can still be made loadable 118 with "options RANDOM_LOADABLE" (e.g., random_fortuna.ko). 119 12020190612: 121 Clang, llvm, lld, lldb, compiler-rt, libc++, libunwind and openmp have 122 been upgraded to 8.0.1. Please see the 20141231 entry below for 123 information about prerequisites and upgrading, if you are not already 124 using clang 3.5.0 or higher. 125 12620190608: 127 A fix was applied to i386 kernel modules to avoid panics with 128 dpcpu or vnet. Users need to recompile i386 kernel modules 129 having pcpu or vnet sections or they will refuse to load. 130 13120190513: 132 User-wired pages now have their own counter, 133 vm.stats.vm.v_user_wire_count. The vm.max_wired sysctl was renamed 134 to vm.max_user_wired and changed from an unsigned int to an unsigned 135 long. bhyve VMs wired with the -S are now subject to the user 136 wiring limit; the vm.max_user_wired sysctl may need to be tuned to 137 avoid running into the limit. 138 13920190507: 140 The IPSEC option has been removed from GENERIC. Users requiring 141 ipsec(4) must now load the ipsec(4) kernel module. 142 14320190507: 144 The tap(4) driver has been folded into tun(4), and the module has been 145 renamed to tuntap. You should update any kld_list="if_tap" or 146 kld_list="if_tun" entries in /etc/rc.conf, if_tap_load="YES" or 147 if_tun_load="YES" entries in /boot/loader.conf to load the if_tuntap 148 module instead, and "device tap" or "device tun" entries in kernel 149 config files to select the tuntap device instead. 150 15120190418: 152 The following knobs have been added related to tradeoffs between 153 safe use of the random device and availability in the absence of 154 entropy: 155 156 kern.random.initial_seeding.bypass_before_seeding: tunable; set 157 non-zero to bypass the random device prior to seeding, or zero to 158 block random requests until the random device is initially seeded. 159 For now, set to 1 (unsafe) by default to restore pre-r346250 boot 160 availability properties. 161 162 kern.random.initial_seeding.read_random_bypassed_before_seeding: 163 read-only diagnostic sysctl that is set when bypass is enabled and 164 read_random(9) is bypassed, to enable programmatic handling of this 165 initial condition, if desired. 166 167 kern.random.initial_seeding.arc4random_bypassed_before_seeding: 168 Similar to the above, but for for arc4random(9) initial seeding. 169 170 kern.random.initial_seeding.disable_bypass_warnings: tunable; set 171 non-zero to disable warnings in dmesg when the same conditions are 172 met as for the diagnostic sysctls above. Defaults to zero, i.e., 173 produce warnings in dmesg when the conditions are met. 174 17520190416: 176 The loadable random module KPI has changed; the random_infra_init() 177 routine now requires a 3rd function pointer for a bool (*)(void) 178 method that returns true if the random device is seeded (and 179 therefore unblocked). 180 18120190404: 182 r345895 reverts r320698. This implies that an nfsuserd(8) daemon 183 built from head sources between r320757 (July 6, 2017) and 184 r338192 (Aug. 22, 2018) will not work unless the "-use-udpsock" 185 is added to the command line. 186 nfsuserd daemons built from head sources that are post-r338192 are 187 not affected and should continue to work. 188 18920190320: 190 The fuse(4) module has been renamed to fusefs(4) for consistency with 191 other filesystems. You should update any kld_load="fuse" entries in 192 /etc/rc.conf, fuse_load="YES" entries in /boot/loader.conf, and 193 "options FUSE" entries in kernel config files. 194 19520190304: 196 Clang, llvm, lld, lldb, compiler-rt and libc++ have been upgraded to 197 8.0.0. Please see the 20141231 entry below for information about 198 prerequisites and upgrading, if you are not already using clang 3.5.0 199 or higher. 200 20120190226: 202 geom_uzip(4) depends on the new module xz. If geom_uzip is statically 203 compiled into your custom kernel, add 'device xz' statement to the 204 kernel config. 205 20620190219: 207 drm and drm2 have been removed from the tree. Please see 208 https://wiki.freebsd.org/Graphics for the latest information on 209 migrating to the drm ports. 210 21120190131: 212 Iflib is no longer unconditionally compiled into the kernel. Drivers 213 using iflib and statically compiled into the kernel, now require 214 the 'device iflib' config option. For the same drivers loaded as 215 modules on kernels not having 'device iflib', the iflib.ko module 216 is loaded automatically. 217 21820190125: 219 The IEEE80211_AMPDU_AGE and AH_SUPPORT_AR5416 kernel configuration 220 options no longer exist since r343219 and r343427 respectively; 221 nothing uses them, so they should be just removed from custom 222 kernel config files. 223 22420181230: 225 r342635 changes the way efibootmgr(8) works by requiring users to add 226 the -b (bootnum) parameter for commands where the bootnum was previously 227 specified with each option. For example 'efibootmgr -B 0001' is now 228 'efibootmgr -B -b 0001'. 229 23020181220: 231 r342286 modifies the NFSv4 server so that it obeys vfs.nfsd.nfs_privport 232 in the same as it is applied to NFSv2 and 3. This implies that NFSv4 233 servers that have vfs.nfsd.nfs_privport set will only allow mounts 234 from clients using a reserved port#. Since both the FreeBSD and Linux 235 NFSv4 clients use reserved port#s by default, this should not affect 236 most NFSv4 mounts. 237 23820181219: 239 The XLP config has been removed. We can't support 64-bit atomics in this 240 kernel because it is running in 32-bit mode. XLP users must transition 241 to running a 64-bit kernel (XLP64 or XLPN32). 242 243 The mips GXEMUL support has been removed from FreeBSD. MALTA* + qemu is 244 the preferred emulator today and we don't need two different ones. 245 246 The old sibyte / swarm / Broadcom BCM1250 support has been 247 removed from the mips port. 248 24920181211: 250 Clang, llvm, lld, lldb, compiler-rt and libc++ have been upgraded to 251 7.0.1. Please see the 20141231 entry below for information about 252 prerequisites and upgrading, if you are not already using clang 3.5.0 253 or higher. 254 25520181211: 256 Remove the timed and netdate programs from the base tree. Setting 257 the time with these daemons has been obsolete for over a decade. 258 25920181126: 260 On amd64, arm64 and armv7 (architectures that install LLVM's ld.lld 261 linker as /usr/bin/ld) GNU ld is no longer installed as ld.bfd, as 262 it produces broken binaries when ifuncs are in use. Users needing 263 GNU ld should install the binutils port or package. 264 26520181123: 266 The BSD crtbegin and crtend code has been enabled by default. It has 267 had extensive testing on amd64, arm64, and i386. It can be disabled 268 by building a world with -DWITHOUT_BSD_CRTBEGIN. 269 27020181115: 271 The set of CTM commands (ctm, ctm_smail, ctm_rmail, ctm_dequeue) 272 has been converted to a port (misc/ctm) and will be removed from 273 FreeBSD-13. It is available as a package (ctm) for all supported 274 FreeBSD versions. 275 27620181110: 277 The default newsyslog.conf(5) file has been changed to only include 278 files in /etc/newsyslog.conf.d/ and /usr/local/etc/newsyslog.conf.d/ if 279 the filenames end in '.conf' and do not begin with a '.'. 280 281 You should check the configuration files in these two directories match 282 this naming convention. You can verify which configuration files are 283 being included using the command: 284 $ newsyslog -Nrv 285 28620181015: 287 Ports for the DRM modules have been simplified. Now, amd64 users should 288 just install the drm-kmod port. All others should install 289 drm-legacy-kmod. 290 291 Graphics hardware that's newer than about 2010 usually works with 292 drm-kmod. For hardware older than 2013, however, some users will need 293 to use drm-legacy-kmod if drm-kmod doesn't work for them. Hardware older 294 than 2008 usually only works in drm-legacy-kmod. The graphics team can 295 only commit to hardware made since 2013 due to the complexity of the 296 market and difficulty to test all the older cards effectively. If you 297 have hardware supported by drm-kmod, you are strongly encouraged to use 298 that as you will get better support. 299 300 Other than KPI chasing, drm-legacy-kmod will not be updated. As outlined 301 elsewhere, the drm and drm2 modules will be eliminated from the src base 302 soon (with a limited exception for arm). Please update to the package 303 asap and report any issues to x11@freebsd.org. 304 305 Generally, anybody using the drm*-kmod packages should add 306 WITHOUT_DRM_MODULE=t and WITHOUT_DRM2_MODULE=t to avoid nasty 307 cross-threading surprises, especially with automatic driver 308 loading from X11 startup. These will become the defaults in 13-current 309 shortly. 310 31120181012: 312 The ixlv(4) driver has been renamed to iavf(4). As a consequence, 313 custom kernel and module loading configuration files must be updated 314 accordingly. Moreover, interfaces previous presented as ixlvN to the 315 system are now exposed as iavfN and network configuration files must 316 be adjusted as necessary. 317 31820181009: 319 OpenSSL has been updated to version 1.1.1. This update included 320 additional various API changes throughout the base system. It is 321 important to rebuild third-party software after upgrading. The value 322 of __FreeBSD_version has been bumped accordingly. 323 32420181006: 325 The legacy DRM modules and drivers have now been added to the loader's 326 module blacklist, in favor of loading them with kld_list in rc.conf(5). 327 The module blacklist may be overridden with the loader.conf(5) 328 'module_blacklist' variable, but loading them via rc.conf(5) is strongly 329 encouraged. 330 33120181002: 332 The cam(4) based nda(4) driver will be used over nvd(4) by default on 333 powerpc64. You may set 'options NVME_USE_NVD=1' in your kernel conf or 334 loader tunable 'hw.nvme.use_nvd=1' if you wish to use the existing 335 driver. Make sure to edit /boot/etc/kboot.conf and fstab to use the 336 nda device name. 337 33820180913: 339 Reproducible build mode is now on by default, in preparation for 340 FreeBSD 12.0. This eliminates build metadata such as the user, 341 host, and time from the kernel (and uname), unless the working tree 342 corresponds to a modified checkout from a version control system. 343 The previous behavior can be obtained by setting the /etc/src.conf 344 knob WITHOUT_REPRODUCIBLE_BUILD. 345 34620180826: 347 The Yarrow CSPRNG has been removed from the kernel as it has not been 348 supported by its designers since at least 2003. Fortuna has been the 349 default since FreeBSD-11. 350 35120180822: 352 devctl freeze/thaw have gone into the tree, the rc scripts have been 353 updated to use them and devmatch has been changed. You should update 354 kernel, userland and rc scripts all at the same time. 355 35620180818: 357 The default interpreter has been switched from 4th to Lua. 358 LOADER_DEFAULT_INTERP, documented in build(7), will override the default 359 interpreter. If you have custom FORTH code you will need to set 360 LOADER_DEFAULT_INTERP=4th (valid values are 4th, lua or simp) in 361 src.conf for the build. This will create default hard links between 362 loader and loader_4th instead of loader and loader_lua, the new default. 363 If you are using UEFI it will create the proper hard link to loader.efi. 364 365 bhyve uses userboot.so. It remains 4th-only until some issues are solved 366 regarding coexisting with multiple versions of FreeBSD are resolved. 367 36820180815: 369 ls(1) now respects the COLORTERM environment variable used in other 370 systems and software to indicate that a colored terminal is both 371 supported and desired. If ls(1) is suddenly emitting colors, they may 372 be disabled again by either removing the unwanted COLORTERM from your 373 environment, or using `ls --color=never`. The ls(1) specific CLICOLOR 374 may not be observed in a future release. 375 37620180808: 377 The default pager for most commands has been changed to "less". To 378 restore the old behavior, set PAGER="more" and MANPAGER="more -s" in 379 your environment. 380 38120180731: 382 The jedec_ts(4) driver has been removed. A superset of its functionality 383 is available in the jedec_dimm(4) driver, and the manpage for that 384 driver includes migration instructions. If you have "device jedec_ts" 385 in your kernel configuration file, it must be removed. 386 38720180730: 388 amd64/GENERIC now has EFI runtime services, EFIRT, enabled by default. 389 This should have no effect if the kernel is booted via BIOS/legacy boot. 390 EFIRT may be disabled via a loader tunable, efi.rt.disabled, if a system 391 has a buggy firmware that prevents a successful boot due to use of 392 runtime services. 393 39420180727: 395 Atmel AT91RM9200 and AT91SAM9, Cavium CNS 11xx and XScale 396 support has been removed from the tree. These ports were 397 obsolete and/or known to be broken for many years. 398 39920180723: 400 loader.efi has been augmented to participate more fully in the 401 UEFI boot manager protocol. loader.efi will now look at the 402 BootXXXX environment variable to determine if a specific kernel 403 or root partition was specified. XXXX is derived from BootCurrent. 404 efibootmgr(8) manages these standard UEFI variables. 405 40620180720: 407 zfsloader's functionality has now been folded into loader. 408 zfsloader is no longer necessary once you've updated your 409 boot blocks. For a transition period, we will install a 410 hardlink for zfsloader to loader to allow a smooth transition 411 until the boot blocks can be updated (hard link because old 412 zfs boot blocks don't understand symlinks). 413 41420180719: 415 ARM64 now have efifb support, if you want to have serial console 416 on your arm64 board when an screen is connected and the bootloader 417 setup a frame buffer for us to use, just add : 418 boot_serial=YES 419 boot_multicons=YES 420 in /boot/loader.conf 421 For Raspberry Pi 3 (RPI) users, this is needed even if you don't have 422 an screen connected as the firmware will setup a frame buffer are that 423 u-boot will expose as an EFI frame buffer. 424 42520180719: 426 New uid:gid added, ntpd:ntpd (123:123). Be sure to run mergemaster 427 or take steps to update /etc/passwd before doing installworld on 428 existing systems. Do not skip the "mergemaster -Fp" step before 429 installworld, as described in the update procedures near the bottom 430 of this document. Also, rc.d/ntpd now starts ntpd(8) as user ntpd 431 if the new mac_ntpd(4) policy is available, unless ntpd_flags or 432 the ntp config file contain options that change file/dir locations. 433 When such options (e.g., "statsdir" or "crypto") are used, ntpd can 434 still be run as non-root by setting ntpd_user=ntpd in rc.conf, after 435 taking steps to ensure that all required files/dirs are accessible 436 by the ntpd user. 437 43820180717: 439 Big endian arm support has been removed. 440 44120180711: 442 The static environment setup in kernel configs is no longer mutually 443 exclusive with the loader(8) environment by default. In order to 444 restore the previous default behavior of disabling the loader(8) 445 environment if a static environment is present, you must specify 446 loader_env.disabled=1 in the static environment. 447 44820180705: 449 The ABI of syscalls used by management tools like sockstat and 450 netstat has been broken to allow 32-bit binaries to work on 451 64-bit kernels without modification. These programs will need 452 to match the kernel in order to function. External programs may 453 require minor modifications to accommodate a change of type in 454 structures from pointers to 64-bit virtual addresses. 455 45620180702: 457 On i386 and amd64 atomics are now inlined. Out of tree modules using 458 atomics will need to be rebuilt. 459 46020180701: 461 The '%I' format in the kern.corefile sysctl limits the number of 462 core files that a process can generate to the number stored in the 463 debug.ncores sysctl. The '%I' format is replaced by the single digit 464 index. Previously, if all indexes were taken the kernel would overwrite 465 only a core file with the highest index in a filename. 466 Currently the system will create a new core file if there is a free 467 index or if all slots are taken it will overwrite the oldest one. 468 46920180630: 470 Clang, llvm, lld, lldb, compiler-rt and libc++ have been upgraded to 471 6.0.1. Please see the 20141231 entry below for information about 472 prerequisites and upgrading, if you are not already using clang 3.5.0 473 or higher. 474 47520180628: 476 r335753 introduced a new quoting method. However, etc/devd/devmatch.conf 477 needed to be changed to work with it. This change was made with r335763 478 and requires a mergemaster / etcupdate / etc to update the installed 479 file. 480 48120180612: 482 r334930 changed the interface between the NFS modules, so they all 483 need to be rebuilt. r335018 did a __FreeBSD_version bump for this. 484 48520180530: 486 As of r334391 lld is the default amd64 system linker; it is installed 487 as /usr/bin/ld. Kernel build workarounds (see 20180510 entry) are no 488 longer necessary. 489 49020180530: 491 The kernel / userland interface for devinfo changed, so you'll 492 need a new kernel and userland as a pair for it to work (rebuilding 493 lib/libdevinfo is all that's required). devinfo and devmatch will 494 not work, but everything else will when there's a mismatch. 495 49620180523: 497 The on-disk format for hwpmc callchain records has changed to include 498 threadid corresponding to a given record. This changes the field offsets 499 and thus requires that libpmcstat be rebuilt before using a kernel 500 later than r334108. 501 50220180517: 503 The vxge(4) driver has been removed. This driver was introduced into 504 HEAD one week before the Exar left the Ethernet market and is not 505 known to be used. If you have device vxge in your kernel config file 506 it must be removed. 507 50820180510: 509 The amd64 kernel now requires a ld that supports ifunc to produce a 510 working kernel, either lld or a newer binutils. lld is built by default 511 on amd64, and the 'buildkernel' target uses it automatically. However, 512 it is not the default linker, so building the kernel the traditional 513 way requires LD=ld.lld on the command line (or LD=/usr/local/bin/ld for 514 binutils port/package). lld will soon be default, and this requirement 515 will go away. 516 517 NOTE: As of r334391 lld is the default system linker on amd64, and no 518 workaround is necessary. 519 52020180508: 521 The nxge(4) driver has been removed. This driver was for PCI-X 10g 522 cards made by s2io/Neterion. The company was acquired by Exar and 523 no longer sells or supports Ethernet products. If you have device 524 nxge in your kernel config file it must be removed. 525 52620180504: 527 The tz database (tzdb) has been updated to 2018e. This version more 528 correctly models time stamps in time zones with negative DST such as 529 Europe/Dublin (from 1971 on), Europe/Prague (1946/7), and 530 Africa/Windhoek (1994/2017). This does not affect the UT offsets, only 531 time zone abbreviations and the tm_isdst flag. 532 53320180502: 534 The ixgb(4) driver has been removed. This driver was for an early and 535 uncommon legacy PCI 10GbE for a single ASIC, Intel 82597EX. Intel 536 quickly shifted to the long lived ixgbe family. If you have device 537 ixgb in your kernel config file it must be removed. 538 53920180501: 540 The lmc(4) driver has been removed. This was a WAN interface 541 card that was already reportedly rare in 2003, and had an ambiguous 542 license. If you have device lmc in your kernel config file it must 543 be removed. 544 54520180413: 546 Support for Arcnet networks has been removed. If you have device 547 arcnet or device cm in your kernel config file they must be 548 removed. 549 55020180411: 551 Support for FDDI networks has been removed. If you have device 552 fddi or device fpa in your kernel config file they must be 553 removed. 554 55520180406: 556 In addition to supporting RFC 3164 formatted messages, the 557 syslogd(8) service is now capable of parsing RFC 5424 formatted 558 log messages. The main benefit of using RFC 5424 is that clients 559 may now send log messages with timestamps containing year numbers, 560 microseconds and time zone offsets. 561 562 Similarly, the syslog(3) C library function has been altered to 563 send RFC 5424 formatted messages to the local system logging 564 daemon. On systems using syslogd(8), this change should have no 565 negative impact, as long as syslogd(8) and the C library are 566 updated at the same time. On systems using a different system 567 logging daemon, it may be necessary to make configuration 568 adjustments, depending on the software used. 569 570 When using syslog-ng, add the 'syslog-protocol' flag to local 571 input sources to enable parsing of RFC 5424 formatted messages: 572 573 source src { 574 unix-dgram("/var/run/log" flags(syslog-protocol)); 575 } 576 577 When using rsyslog, disable the 'SysSock.UseSpecialParser' option 578 of the 'imuxsock' module to let messages be processed by the 579 regular RFC 3164/5424 parsing pipeline: 580 581 module(load="imuxsock" SysSock.UseSpecialParser="off") 582 583 Do note that these changes only affect communication between local 584 applications and syslogd(8). The format that syslogd(8) uses to 585 store messages on disk or forward messages to other systems 586 remains unchanged. syslogd(8) still uses RFC 3164 for these 587 purposes. Options to customize this behaviour will be added in the 588 future. Utilities that process log files stored in /var/log are 589 thus expected to continue to function as before. 590 591 __FreeBSD_version has been incremented to 1200061 to denote this 592 change. 593 59420180328: 595 Support for token ring networks has been removed. If you 596 have "device token" in your kernel config you should remove 597 it. No device drivers supported token ring. 598 59920180323: 600 makefs was modified to be able to tag ISO9660 El Torito boot catalog 601 entries as EFI instead of overloading the i386 tag as done previously. 602 The amd64 mkisoimages.sh script used to build amd64 ISO images for 603 release was updated to use this. This may mean that makefs must be 604 updated before "make cdrom" can be run in the release directory. This 605 should be as simple as: 606 607 $ cd $SRCDIR/usr.sbin/makefs 608 $ make depend all install 609 61020180212: 611 FreeBSD boot loader enhanced with Lua scripting. It's purely opt-in for 612 now by building WITH_LOADER_LUA and WITHOUT_FORTH in /etc/src.conf. 613 Co-existence for the transition period will come shortly. Booting is a 614 complex environment and test coverage for Lua-enabled loaders has been 615 thin, so it would be prudent to assume it might not work and make 616 provisions for backup boot methods. 617 61820180211: 619 devmatch functionality has been turned on in devd. It will automatically 620 load drivers for unattached devices. This may cause unexpected drivers 621 to be loaded. Please report any problems to current@ and 622 imp@freebsd.org. 623 62420180114: 625 Clang, llvm, lld, lldb, compiler-rt and libc++ have been upgraded to 626 6.0.0. Please see the 20141231 entry below for information about 627 prerequisites and upgrading, if you are not already using clang 3.5.0 628 or higher. 629 63020180110: 631 LLVM's lld linker is now used as the FreeBSD/amd64 bootstrap linker. 632 This means it is used to link the kernel and userland libraries and 633 executables, but is not yet installed as /usr/bin/ld by default. 634 635 To revert to ld.bfd as the bootstrap linker, in /etc/src.conf set 636 WITHOUT_LLD_BOOTSTRAP=yes 637 63820180110: 639 On i386, pmtimer has been removed. Its functionality has been folded 640 into apm. It was a no-op on ACPI in current for a while now (but was 641 still needed on i386 in FreeBSD 11 and earlier). Users may need to 642 remove it from kernel config files. 643 64420180104: 645 The use of RSS hash from the network card aka flowid has been 646 disabled by default for lagg(4) as it's currently incompatible with 647 the lacp and loadbalance protocols. 648 649 This can be re-enabled by setting the following in loader.conf: 650 net.link.lagg.default_use_flowid="1" 651 65220180102: 653 The SW_WATCHDOG option is no longer necessary to enable the 654 hardclock-based software watchdog if no hardware watchdog is 655 configured. As before, SW_WATCHDOG will cause the software 656 watchdog to be enabled even if a hardware watchdog is configured. 657 65820171215: 659 r326887 fixes the issue described in the 20171214 UPDATING entry. 660 r326888 flips the switch back to building GELI support always. 661 66220171214: 663 r362593 broke ZFS + GELI support for reasons unknown. However, 664 it also broke ZFS support generally, so GELI has been turned off 665 by default as the lesser evil in r326857. If you boot off ZFS and/or 666 GELI, it might not be a good time to update. 667 66820171125: 669 PowerPC users must update loader(8) by rebuilding world before 670 installing a new kernel, as the protocol connecting them has 671 changed. Without the update, loader metadata will not be passed 672 successfully to the kernel and users will have to enter their 673 root partition at the kernel mountroot prompt to continue booting. 674 Newer versions of loader can boot old kernels without issue. 675 67620171110: 677 The LOADER_FIREWIRE_SUPPORT build variable as been renamed to 678 WITH/OUT_LOADER_FIREWIRE. LOADER_{NO_,}GELI_SUPPORT has been renamed 679 to WITH/OUT_LOADER_GELI. 680 68120171106: 682 The naive and non-compliant support of posix_fallocate(2) in ZFS 683 has been removed as of r325320. The system call now returns EINVAL 684 when used on a ZFS file. Although the new behavior complies with the 685 standard, some consumers are not prepared to cope with it. 686 One known victim is lld prior to r325420. 687 68820171102: 689 Building in a FreeBSD src checkout will automatically create object 690 directories now rather than store files in the current directory if 691 'make obj' was not ran. Calling 'make obj' is no longer necessary. 692 This feature can be disabled by setting WITHOUT_AUTO_OBJ=yes in 693 /etc/src-env.conf (not /etc/src.conf), or passing the option in the 694 environment. 695 69620171101: 697 The default MAKEOBJDIR has changed from /usr/obj/<srcdir> for native 698 builds, and /usr/obj/<arch>/<srcdir> for cross-builds, to a unified 699 /usr/obj/<srcdir>/<arch>. This behavior can be changed to the old 700 format by setting WITHOUT_UNIFIED_OBJDIR=yes in /etc/src-env.conf, 701 the environment, or with -DWITHOUT_UNIFIED_OBJDIR when building. 702 The UNIFIED_OBJDIR option is a transitional feature that will be 703 removed for 12.0 release; please migrate to the new format for any 704 tools by looking up the OBJDIR used by 'make -V .OBJDIR' means rather 705 than hardcoding paths. 706 70720171028: 708 The native-xtools target no longer installs the files by default to the 709 OBJDIR. Use the native-xtools-install target with a DESTDIR to install 710 to ${DESTDIR}/${NXTP} where NXTP defaults to /nxb-bin. 711 71220171021: 713 As part of the boot loader infrastructure cleanup, LOADER_*_SUPPORT 714 options are changing from controlling the build if defined / undefined 715 to controlling the build with explicit 'yes' or 'no' values. They will 716 shift to WITH/WITHOUT options to match other options in the system. 717 71820171010: 719 libstand has turned into a private library for sys/boot use only. 720 It is no longer supported as a public interface outside of sys/boot. 721 72220171005: 723 The arm port has split armv6 into armv6 and armv7. armv7 is now 724 a valid TARGET_ARCH/MACHINE_ARCH setting. If you have an armv7 system 725 and are running a kernel from before r324363, you will need to add 726 MACHINE_ARCH=armv7 to 'make buildworld' to do a native build. 727 72820171003: 729 When building multiple kernels using KERNCONF, non-existent KERNCONF 730 files will produce an error and buildkernel will fail. Previously 731 missing KERNCONF files silently failed giving no indication as to 732 why, only to subsequently discover during installkernel that the 733 desired kernel was never built in the first place. 734 73520170912: 736 The default serial number format for CTL LUNs has changed. This will 737 affect users who use /dev/diskid/* device nodes, or whose FibreChannel 738 or iSCSI clients care about their LUNs' serial numbers. Users who 739 require serial number stability should hardcode serial numbers in 740 /etc/ctl.conf . 741 74220170912: 743 For 32-bit arm compiled for hard-float support, soft-floating point 744 binaries now always get their shared libraries from 745 LD_SOFT_LIBRARY_PATH (in the past, this was only used if 746 /usr/libsoft also existed). Only users with a hard-float ld.so, but 747 soft-float everything else should be affected. 748 74920170826: 750 The geli password typed at boot is now hidden. To restore the previous 751 behavior, see geli(8) for configuration options. 752 75320170825: 754 Move PMTUD blackhole counters to TCPSTATS and remove them from bare 755 sysctl values. Minor nit, but requires a rebuild of both world/kernel 756 to complete. 757 75820170814: 759 "make check" behavior (made in ^/head@r295380) has been changed to 760 execute from a limited sandbox, as opposed to executing from 761 ${TESTSDIR}. 762 763 Behavioral changes: 764 - The "beforecheck" and "aftercheck" targets are now specified. 765 - ${CHECKDIR} (added in commit noted above) has been removed. 766 - Legacy behavior can be enabled by setting 767 WITHOUT_MAKE_CHECK_USE_SANDBOX in src.conf(5) or the environment. 768 769 If the limited sandbox mode is enabled, "make check" will execute 770 "make distribution", then install, execute the tests, and clean up the 771 sandbox if successful. 772 773 The "make distribution" and "make install" targets are typically run as 774 root to set appropriate permissions and ownership at installation time. 775 The end-user should set "WITH_INSTALL_AS_USER" in src.conf(5) or the 776 environment if executing "make check" with limited sandbox mode using 777 an unprivileged user. 778 77920170808: 780 Since the switch to GPT disk labels, fsck for UFS/FFS has been 781 unable to automatically find alternate superblocks. As of r322297, 782 the information needed to find alternate superblocks has been 783 moved to the end of the area reserved for the boot block. 784 Filesystems created with a newfs of this vintage or later 785 will create the recovery information. If you have a filesystem 786 created prior to this change and wish to have a recovery block 787 created for your filesystem, you can do so by running fsck in 788 foreground mode (i.e., do not use the -p or -y options). As it 789 starts, fsck will ask ``SAVE DATA TO FIND ALTERNATE SUPERBLOCKS'' 790 to which you should answer yes. 791 79220170728: 793 As of r321665, an NFSv4 server configuration that services 794 Kerberos mounts or clients that do not support the uid/gid in 795 owner/owner_group string capability, must explicitly enable 796 the nfsuserd daemon by adding nfsuserd_enable="YES" to the 797 machine's /etc/rc.conf file. 798 79920170722: 800 Clang, llvm, lldb, compiler-rt and libc++ have been upgraded to 5.0.0. 801 Please see the 20141231 entry below for information about prerequisites 802 and upgrading, if you are not already using clang 3.5.0 or higher. 803 80420170701: 805 WITHOUT_RCMDS is now the default. Set WITH_RCMDS if you need the 806 r-commands (rlogin, rsh, etc.) to be built with the base system. 807 80820170625: 809 The FreeBSD/powerpc platform now uses a 64-bit type for time_t. This is 810 a very major ABI incompatible change, so users of FreeBSD/powerpc must 811 be careful when performing source upgrades. It is best to run 812 'make installworld' from an alternate root system, either a live 813 CD/memory stick, or a temporary root partition. Additionally, all ports 814 must be recompiled. powerpc64 is largely unaffected, except in the case 815 of 32-bit compatibility. All 32-bit binaries will be affected. 816 81720170623: 818 Forward compatibility for the "ino64" project have been committed. This 819 will allow most new binaries to run on older kernels in a limited 820 fashion. This prevents many of the common foot-shooting actions in the 821 upgrade as well as the limited ability to roll back the kernel across 822 the ino64 upgrade. Complicated use cases may not work properly, though 823 enough simpler ones work to allow recovery in most situations. 824 82520170620: 826 Switch back to the BSDL dtc (Device Tree Compiler). Set WITH_GPL_DTC 827 if you require the GPL compiler. 828 82920170618: 830 The internal ABI used for communication between the NFS kernel modules 831 was changed by r320085, so __FreeBSD_version was bumped to 832 ensure all the NFS related modules are updated together. 833 83420170617: 835 The ABI of struct event was changed by extending the data 836 member to 64bit and adding ext fields. For upgrade, same 837 precautions as for the entry 20170523 "ino64" must be 838 followed. 839 84020170531: 841 The GNU roff toolchain has been removed from base. To render manpages 842 which are not supported by mandoc(1), man(1) can fallback on GNU roff 843 from ports (and recommends to install it). 844 To render roff(7) documents, consider using GNU roff from ports or the 845 heirloom doctools roff toolchain from ports via pkg install groff or 846 via pkg install heirloom-doctools. 847 84820170524: 849 The ath(4) and ath_hal(4) modules now build piecemeal to allow for 850 smaller runtime footprint builds. This is useful for embedded systems 851 which only require one chipset support. 852 853 If you load it as a module, make sure this is in /boot/loader.conf: 854 855 if_ath_load="YES" 856 857 This will load the HAL, all chip/RF backends and if_ath_pci. 858 If you have if_ath_pci in /boot/loader.conf, ensure it is after 859 if_ath or it will not load any HAL chipset support. 860 861 If you want to selectively load things (eg on ye cheape ARM/MIPS 862 platforms where RAM is at a premium) you should: 863 864 * load ath_hal 865 * load the chip modules in question 866 * load ath_rate, ath_dfs 867 * load ath_main 868 * load if_ath_pci and/or if_ath_ahb depending upon your particular 869 bus bind type - this is where probe/attach is done. 870 871 For further comments/feedback, poke adrian@ . 872 87320170523: 874 The "ino64" 64-bit inode project has been committed, which extends 875 a number of types to 64 bits. Upgrading in place requires care and 876 adherence to the documented upgrade procedure. 877 878 If using a custom kernel configuration ensure that the 879 COMPAT_FREEBSD11 option is included (as during the upgrade the 880 system will be running the ino64 kernel with the existing world). 881 882 For the safest in-place upgrade begin by removing previous build 883 artifacts via "rm -rf /usr/obj/*". Then, carefully follow the full 884 procedure documented below under the heading "To rebuild everything and 885 install it on the current system." Specifically, a reboot is required 886 after installing the new kernel before installing world. While an 887 installworld normally works by accident from multiuser after rebooting 888 the proper kernel, there are many cases where this will fail across this 889 upgrade and installworld from single user is required. 890 89120170424: 892 The NATM framework including the en(4), fatm(4), hatm(4), and 893 patm(4) devices has been removed. Consumers should plan a 894 migration before the end-of-life date for FreeBSD 11. 895 89620170420: 897 GNU diff has been replaced by a BSD licensed diff. Some features of GNU 898 diff has not been implemented, if those are needed a newer version of 899 GNU diff is available via the diffutils package under the gdiff name. 900 90120170413: 902 As of r316810 for ipfilter, keep frags is no longer assumed when 903 keep state is specified in a rule. r316810 aligns ipfilter with 904 documentation in man pages separating keep frags from keep state. 905 This allows keep state to be specified without forcing keep frags 906 and allows keep frags to be specified independently of keep state. 907 To maintain previous behaviour, also specify keep frags with 908 keep state (as documented in ipf.conf.5). 909 91020170407: 911 arm64 builds now use the base system LLD 4.0.0 linker by default, 912 instead of requiring that the aarch64-binutils port or package be 913 installed. To continue using aarch64-binutils, set 914 CROSS_BINUTILS_PREFIX=/usr/local/aarch64-freebsd/bin . 915 91620170405: 917 The UDP optimization in entry 20160818 that added the sysctl 918 net.inet.udp.require_l2_bcast has been reverted. L2 broadcast 919 packets will no longer be treated as L3 broadcast packets. 920 92120170331: 922 Binds and sends to the loopback addresses, IPv6 and IPv4, will now 923 use any explicitly assigned loopback address available in the jail 924 instead of using the first assigned address of the jail. 925 92620170329: 927 The ctl.ko module no longer implements the iSCSI target frontend: 928 cfiscsi.ko does instead. 929 930 If building cfiscsi.ko as a kernel module, the module can be loaded 931 via one of the following methods: 932 - `cfiscsi_load="YES"` in loader.conf(5). 933 - Add `cfiscsi` to `$kld_list` in rc.conf(5). 934 - ctladm(8)/ctld(8), when compiled with iSCSI support 935 (`WITH_ISCSI=yes` in src.conf(5)) 936 937 Please see cfiscsi(4) for more details. 938 93920170316: 940 The mmcsd.ko module now additionally depends on geom_flashmap.ko. 941 Also, mmc.ko and mmcsd.ko need to be a matching pair built from the 942 same source (previously, the dependency of mmcsd.ko on mmc.ko was 943 missing, but mmcsd.ko now will refuse to load if it is incompatible 944 with mmc.ko). 945 94620170315: 947 The syntax of ipfw(8) named states was changed to avoid ambiguity. 948 If you have used named states in the firewall rules, you need to modify 949 them after installworld and before rebooting. Now named states must 950 be prefixed with colon. 951 95220170311: 953 The old drm (sys/dev/drm/) drivers for i915 and radeon have been 954 removed as the userland we provide cannot use them. The KMS version 955 (sys/dev/drm2) supports the same hardware. 956 95720170302: 958 Clang, llvm, lldb, compiler-rt and libc++ have been upgraded to 4.0.0. 959 Please see the 20141231 entry below for information about prerequisites 960 and upgrading, if you are not already using clang 3.5.0 or higher. 961 96220170221: 963 The code that provides support for ZFS .zfs/ directory functionality 964 has been reimplemented. It's not possible now to create a snapshot 965 by mkdir under .zfs/snapshot/. That should be the only user visible 966 change. 967 96820170216: 969 EISA bus support has been removed. The WITH_EISA option is no longer 970 valid. 971 97220170215: 973 MCA bus support has been removed. 974 97520170127: 976 The WITH_LLD_AS_LD / WITHOUT_LLD_AS_LD build knobs have been renamed 977 WITH_LLD_IS_LD / WITHOUT_LLD_IS_LD, for consistency with CLANG_IS_CC. 978 97920170112: 980 The EM_MULTIQUEUE kernel configuration option is deprecated now that 981 the em(4) driver conforms to iflib specifications. 982 98320170109: 984 The igb(4), em(4) and lem(4) ethernet drivers are now implemented via 985 IFLIB. If you have a custom kernel configuration that excludes em(4) 986 but you use igb(4), you need to re-add em(4) to your custom 987 configuration. 988 98920161217: 990 Clang, llvm, lldb, compiler-rt and libc++ have been upgraded to 3.9.1. 991 Please see the 20141231 entry below for information about prerequisites 992 and upgrading, if you are not already using clang 3.5.0 or higher. 993 99420161124: 995 Clang, llvm, lldb, compiler-rt and libc++ have been upgraded to 3.9.0. 996 Please see the 20141231 entry below for information about prerequisites 997 and upgrading, if you are not already using clang 3.5.0 or higher. 998 99920161119: 1000 The layout of the pmap structure has changed for powerpc to put the pmap 1001 statistics at the front for all CPU variations. libkvm(3) and all tools 1002 that link against it need to be recompiled. 1003 100420161030: 1005 isl(4) and cyapa(4) drivers now require a new driver, 1006 chromebook_platform(4), to work properly on Chromebook-class hardware. 1007 On other types of hardware the drivers may need to be configured using 1008 device hints. Please see the corresponding manual pages for details. 1009 101020161017: 1011 The urtwn(4) driver was merged into rtwn(4) and now consists of 1012 rtwn(4) main module + rtwn_usb(4) and rtwn_pci(4) bus-specific 1013 parts. 1014 Also, firmware for RTL8188CE was renamed due to possible name 1015 conflict (rtwnrtl8192cU(B) -> rtwnrtl8192cE(B)) 1016 101720161015: 1018 GNU rcs has been removed from base. It is available as packages: 1019 - rcs: Latest GPLv3 GNU rcs version. 1020 - rcs57: Copy of the latest version of GNU rcs (GPLv2) before it was 1021 removed from base. 1022 102320161008: 1024 Use of the cc_cdg, cc_chd, cc_hd, or cc_vegas congestion control 1025 modules now requires that the kernel configuration contain the 1026 TCP_HHOOK option. (This option is included in the GENERIC kernel.) 1027 102820161003: 1029 The WITHOUT_ELFCOPY_AS_OBJCOPY src.conf(5) knob has been retired. 1030 ELF Tool Chain's elfcopy is always installed as /usr/bin/objcopy. 1031 103220160924: 1033 Relocatable object files with the extension of .So have been renamed 1034 to use an extension of .pico instead. The purpose of this change is 1035 to avoid a name clash with shared libraries on case-insensitive file 1036 systems. On those file systems, foo.So is the same file as foo.so. 1037 103820160918: 1039 GNU rcs has been turned off by default. It can (temporarily) be built 1040 again by adding WITH_RCS knob in src.conf. 1041 Otherwise, GNU rcs is available from packages: 1042 - rcs: Latest GPLv3 GNU rcs version. 1043 - rcs57: Copy of the latest version of GNU rcs (GPLv2) from base. 1044 104520160918: 1046 The backup_uses_rcs functionality has been removed from rc.subr. 1047 104820160908: 1049 The queue(3) debugging macro, QUEUE_MACRO_DEBUG, has been split into 1050 two separate components, QUEUE_MACRO_DEBUG_TRACE and 1051 QUEUE_MACRO_DEBUG_TRASH. Define both for the original 1052 QUEUE_MACRO_DEBUG behavior. 1053 105420160824: 1055 r304787 changed some ioctl interfaces between the iSCSI userspace 1056 programs and the kernel. ctladm, ctld, iscsictl, and iscsid must be 1057 rebuilt to work with new kernels. __FreeBSD_version has been bumped 1058 to 1200005. 1059 106020160818: 1061 The UDP receive code has been updated to only treat incoming UDP 1062 packets that were addressed to an L2 broadcast address as L3 1063 broadcast packets. It is not expected that this will affect any 1064 standards-conforming UDP application. The new behaviour can be 1065 disabled by setting the sysctl net.inet.udp.require_l2_bcast to 1066 0. 1067 106820160818: 1069 Remove the openbsd_poll system call. 1070 __FreeBSD_version has been bumped because of this. 1071 107220160708: 1073 The stable/11 branch has been created from head@r302406. 1074 107520160622: 1076 The libc stub for the pipe(2) system call has been replaced with 1077 a wrapper that calls the pipe2(2) system call and the pipe(2) 1078 system call is now only implemented by the kernels that include 1079 "options COMPAT_FREEBSD10" in their config file (this is the 1080 default). Users should ensure that this option is enabled in 1081 their kernel or upgrade userspace to r302092 before upgrading their 1082 kernel. 1083 108420160527: 1085 CAM will now strip leading spaces from SCSI disks' serial numbers. 1086 This will affect users who create UFS filesystems on SCSI disks using 1087 those disk's diskid device nodes. For example, if /etc/fstab 1088 previously contained a line like 1089 "/dev/diskid/DISK-%20%20%20%20%20%20%20ABCDEFG0123456", you should 1090 change it to "/dev/diskid/DISK-ABCDEFG0123456". Users of geom 1091 transforms like gmirror may also be affected. ZFS users should 1092 generally be fine. 1093 109420160523: 1095 The bitstring(3) API has been updated with new functionality and 1096 improved performance. But it is binary-incompatible with the old API. 1097 Objects built with the new headers may not be linked against objects 1098 built with the old headers. 1099 110020160520: 1101 The brk and sbrk functions have been removed from libc on arm64. 1102 Binutils from ports has been updated to not link to these 1103 functions and should be updated to the latest version before 1104 installing a new libc. 1105 110620160517: 1107 The armv6 port now defaults to hard float ABI. Limited support 1108 for running both hardfloat and soft float on the same system 1109 is available using the libraries installed with -DWITH_LIBSOFT. 1110 This has only been tested as an upgrade path for installworld 1111 and packages may fail or need manual intervention to run. New 1112 packages will be needed. 1113 1114 To update an existing self-hosted armv6hf system, you must add 1115 TARGET_ARCH=armv6 on the make command line for both the build 1116 and the install steps. 1117 111820160510: 1119 Kernel modules compiled outside of a kernel build now default to 1120 installing to /boot/modules instead of /boot/kernel. Many kernel 1121 modules built this way (such as those in ports) already overrode 1122 KMODDIR explicitly to install into /boot/modules. However, 1123 manually building and installing a module from /sys/modules will 1124 now install to /boot/modules instead of /boot/kernel. 1125 112620160414: 1127 The CAM I/O scheduler has been committed to the kernel. There should be 1128 no user visible impact. This does enable NCQ Trim on ada SSDs. While the 1129 list of known rogues that claim support for this but actually corrupt 1130 data is believed to be complete, be on the lookout for data 1131 corruption. The known rogue list is believed to be complete: 1132 1133 o Crucial MX100, M550 drives with MU01 firmware. 1134 o Micron M510 and M550 drives with MU01 firmware. 1135 o Micron M500 prior to MU07 firmware 1136 o Samsung 830, 840, and 850 all firmwares 1137 o FCCT M500 all firmwares 1138 1139 Crucial has firmware http://www.crucial.com/usa/en/support-ssd-firmware 1140 with working NCQ TRIM. For Micron branded drives, see your sales rep for 1141 updated firmware. Black listed drives will work correctly because these 1142 drives work correctly so long as no NCQ TRIMs are sent to them. Given 1143 this list is the same as found in Linux, it's believed there are no 1144 other rogues in the market place. All other models from the above 1145 vendors work. 1146 1147 To be safe, if you are at all concerned, you can quirk each of your 1148 drives to prevent NCQ from being sent by setting: 1149 kern.cam.ada.X.quirks="0x2" 1150 in loader.conf. If the drive requires the 4k sector quirk, set the 1151 quirks entry to 0x3. 1152 115320160330: 1154 The FAST_DEPEND build option has been removed and its functionality is 1155 now the one true way. The old mkdep(1) style of 'make depend' has 1156 been removed. See 20160311 for further details. 1157 115820160317: 1159 Resource range types have grown from unsigned long to uintmax_t. All 1160 drivers, and anything using libdevinfo, need to be recompiled. 1161 116220160311: 1163 WITH_FAST_DEPEND is now enabled by default for in-tree and out-of-tree 1164 builds. It no longer runs mkdep(1) during 'make depend', and the 1165 'make depend' stage can safely be skipped now as it is auto ran 1166 when building 'make all' and will generate all SRCS and DPSRCS before 1167 building anything else. Dependencies are gathered at compile time with 1168 -MF flags kept in separate .depend files per object file. Users should 1169 run 'make cleandepend' once if using -DNO_CLEAN to clean out older 1170 stale .depend files. 1171 117220160306: 1173 On amd64, clang 3.8.0 can now insert sections of type AMD64_UNWIND into 1174 kernel modules. Therefore, if you load any kernel modules at boot time, 1175 please install the boot loaders after you install the kernel, but before 1176 rebooting, e.g.: 1177 1178 make buildworld 1179 make buildkernel KERNCONF=YOUR_KERNEL_HERE 1180 make installkernel KERNCONF=YOUR_KERNEL_HERE 1181 make -C sys/boot install 1182 <reboot in single user> 1183 1184 Then follow the usual steps, described in the General Notes section, 1185 below. 1186 118720160305: 1188 Clang, llvm, lldb and compiler-rt have been upgraded to 3.8.0. Please 1189 see the 20141231 entry below for information about prerequisites and 1190 upgrading, if you are not already using clang 3.5.0 or higher. 1191 119220160301: 1193 The AIO subsystem is now a standard part of the kernel. The 1194 VFS_AIO kernel option and aio.ko kernel module have been removed. 1195 Due to stability concerns, asynchronous I/O requests are only 1196 permitted on sockets and raw disks by default. To enable 1197 asynchronous I/O requests on all file types, set the 1198 vfs.aio.enable_unsafe sysctl to a non-zero value. 1199 120020160226: 1201 The ELF object manipulation tool objcopy is now provided by the 1202 ELF Tool Chain project rather than by GNU binutils. It should be a 1203 drop-in replacement, with the addition of arm64 support. The 1204 (temporary) src.conf knob WITHOUT_ELFCOPY_AS_OBJCOPY knob may be set 1205 to obtain the GNU version if necessary. 1206 120720160129: 1208 Building ZFS pools on top of zvols is prohibited by default. That 1209 feature has never worked safely; it's always been prone to deadlocks. 1210 Using a zvol as the backing store for a VM guest's virtual disk will 1211 still work, even if the guest is using ZFS. Legacy behavior can be 1212 restored by setting vfs.zfs.vol.recursive=1. 1213 121420160119: 1215 The NONE and HPN patches has been removed from OpenSSH. They are 1216 still available in the security/openssh-portable port. 1217 121820160113: 1219 With the addition of ypldap(8), a new _ypldap user is now required 1220 during installworld. "mergemaster -p" can be used to add the user 1221 prior to installworld, as documented in the handbook. 1222 122320151216: 1224 The tftp loader (pxeboot) now uses the option root-path directive. As a 1225 consequence it no longer looks for a pxeboot.4th file on the tftp 1226 server. Instead it uses the regular /boot infrastructure as with the 1227 other loaders. 1228 122920151211: 1230 The code to start recording plug and play data into the modules has 1231 been committed. While the old tools will properly build a new kernel, 1232 a number of warnings about "unknown metadata record 4" will be produced 1233 for an older kldxref. To avoid such warnings, make sure to rebuild 1234 the kernel toolchain (or world). Make sure that you have r292078 or 1235 later when trying to build 292077 or later before rebuilding. 1236 123720151207: 1238 Debug data files are now built by default with 'make buildworld' and 1239 installed with 'make installworld'. This facilitates debugging but 1240 requires more disk space both during the build and for the installed 1241 world. Debug files may be disabled by setting WITHOUT_DEBUG_FILES=yes 1242 in src.conf(5). 1243 124420151130: 1245 r291527 changed the internal interface between the nfsd.ko and 1246 nfscommon.ko modules. As such, they must both be upgraded to-gether. 1247 __FreeBSD_version has been bumped because of this. 1248 124920151108: 1250 Add support for unicode collation strings leads to a change of 1251 order of files listed by ls(1) for example. To get back to the old 1252 behaviour, set LC_COLLATE environment variable to "C". 1253 1254 Databases administrators will need to reindex their databases given 1255 collation results will be different. 1256 1257 Due to a bug in install(1) it is recommended to remove the ancient 1258 locales before running make installworld. 1259 1260 rm -rf /usr/share/locale/* 1261 126220151030: 1263 The OpenSSL has been upgraded to 1.0.2d. Any binaries requiring 1264 libcrypto.so.7 or libssl.so.7 must be recompiled. 1265 126620151020: 1267 Qlogic 24xx/25xx firmware images were updated from 5.5.0 to 7.3.0. 1268 Kernel modules isp_2400_multi and isp_2500_multi were removed and 1269 should be replaced with isp_2400 and isp_2500 modules respectively. 1270 127120151017: 1272 The build previously allowed using 'make -n' to not recurse into 1273 sub-directories while showing what commands would be executed, and 1274 'make -n -n' to recursively show commands. Now 'make -n' will recurse 1275 and 'make -N' will not. 1276 127720151012: 1278 If you specify SENDMAIL_MC or SENDMAIL_CF in make.conf, mergemaster 1279 and etcupdate will now use this file. A custom sendmail.cf is now 1280 updated via this mechanism rather than via installworld. If you had 1281 excluded sendmail.cf in mergemaster.rc or etcupdate.conf, you may 1282 want to remove the exclusion or change it to "always install". 1283 /etc/mail/sendmail.cf is now managed the same way regardless of 1284 whether SENDMAIL_MC/SENDMAIL_CF is used. If you are not using 1285 SENDMAIL_MC/SENDMAIL_CF there should be no change in behavior. 1286 128720151011: 1288 Compatibility shims for legacy ATA device names have been removed. 1289 It includes ATA_STATIC_ID kernel option, kern.cam.ada.legacy_aliases 1290 and kern.geom.raid.legacy_aliases loader tunables, kern.devalias.* 1291 environment variables, /dev/ad* and /dev/ar* symbolic links. 1292 129320151006: 1294 Clang, llvm, lldb, compiler-rt and libc++ have been upgraded to 3.7.0. 1295 Please see the 20141231 entry below for information about prerequisites 1296 and upgrading, if you are not already using clang 3.5.0 or higher. 1297 129820150924: 1299 Kernel debug files have been moved to /usr/lib/debug/boot/kernel/, 1300 and renamed from .symbols to .debug. This reduces the size requirements 1301 on the boot partition or file system and provides consistency with 1302 userland debug files. 1303 1304 When using the supported kernel installation method the 1305 /usr/lib/debug/boot/kernel directory will be renamed (to kernel.old) 1306 as is done with /boot/kernel. 1307 1308 Developers wishing to maintain the historical behavior of installing 1309 debug files in /boot/kernel/ can set KERN_DEBUGDIR="" in src.conf(5). 1310 131120150827: 1312 The wireless drivers had undergone changes that remove the 'parent 1313 interface' from the ifconfig -l output. The rc.d network scripts 1314 used to check presence of a parent interface in the list, so old 1315 scripts would fail to start wireless networking. Thus, etcupdate(3) 1316 or mergemaster(8) run is required after kernel update, to update your 1317 rc.d scripts in /etc. 1318 131920150827: 1320 pf no longer supports 'scrub fragment crop' or 'scrub fragment drop-ovl' 1321 These configurations are now automatically interpreted as 1322 'scrub fragment reassemble'. 1323 132420150817: 1325 Kernel-loadable modules for the random(4) device are back. To use 1326 them, the kernel must have 1327 1328 device random 1329 options RANDOM_LOADABLE 1330 1331 kldload(8) can then be used to load random_fortuna.ko 1332 or random_yarrow.ko. Please note that due to the indirect 1333 function calls that the loadable modules need to provide, 1334 the build-in variants will be slightly more efficient. 1335 1336 The random(4) kernel option RANDOM_DUMMY has been retired due to 1337 unpopularity. It was not all that useful anyway. 1338 133920150813: 1340 The WITHOUT_ELFTOOLCHAIN_TOOLS src.conf(5) knob has been retired. 1341 Control over building the ELF Tool Chain tools is now provided by 1342 the WITHOUT_TOOLCHAIN knob. 1343 134420150810: 1345 The polarity of Pulse Per Second (PPS) capture events with the 1346 uart(4) driver has been corrected. Prior to this change the PPS 1347 "assert" event corresponded to the trailing edge of a positive PPS 1348 pulse and the "clear" event was the leading edge of the next pulse. 1349 1350 As the width of a PPS pulse in a typical GPS receiver is on the 1351 order of 1 millisecond, most users will not notice any significant 1352 difference with this change. 1353 1354 Anyone who has compensated for the historical polarity reversal by 1355 configuring a negative offset equal to the pulse width will need to 1356 remove that workaround. 1357 135820150809: 1359 The default group assigned to /dev/dri entries has been changed 1360 from 'wheel' to 'video' with the id of '44'. If you want to have 1361 access to the dri devices please add yourself to the video group 1362 with: 1363 1364 # pw groupmod video -m $USER 1365 136620150806: 1367 The menu.rc and loader.rc files will now be replaced during 1368 upgrades. Please migrate local changes to menu.rc.local and 1369 loader.rc.local instead. 1370 137120150805: 1372 GNU Binutils versions of addr2line, c++filt, nm, readelf, size, 1373 strings and strip have been removed. The src.conf(5) knob 1374 WITHOUT_ELFTOOLCHAIN_TOOLS no longer provides the binutils tools. 1375 137620150728: 1377 As ZFS requires more kernel stack pages than is the default on some 1378 architectures e.g. i386, it now warns if KSTACK_PAGES is less than 1379 ZFS_MIN_KSTACK_PAGES (which is 4 at the time of writing). 1380 1381 Please consider using 'options KSTACK_PAGES=X' where X is greater 1382 than or equal to ZFS_MIN_KSTACK_PAGES i.e. 4 in such configurations. 1383 138420150706: 1385 sendmail has been updated to 8.15.2. Starting with FreeBSD 11.0 1386 and sendmail 8.15, sendmail uses uncompressed IPv6 addresses by 1387 default, i.e., they will not contain "::". For example, instead 1388 of ::1, it will be 0:0:0:0:0:0:0:1. This permits a zero subnet 1389 to have a more specific match, such as different map entries for 1390 IPv6:0:0 vs IPv6:0. This change requires that configuration 1391 data (including maps, files, classes, custom ruleset, etc.) must 1392 use the same format, so make certain such configuration data is 1393 upgrading. As a very simple check search for patterns like 1394 'IPv6:[0-9a-fA-F:]*::' and 'IPv6::'. To return to the old 1395 behavior, set the m4 option confUSE_COMPRESSED_IPV6_ADDRESSES or 1396 the cf option UseCompressedIPv6Addresses. 1397 139820150630: 1399 The default kernel entropy-processing algorithm is now 1400 Fortuna, replacing Yarrow. 1401 1402 Assuming you have 'device random' in your kernel config 1403 file, the configurations allow a kernel option to override 1404 this default. You may choose *ONE* of: 1405 1406 options RANDOM_YARROW # Legacy /dev/random algorithm. 1407 options RANDOM_DUMMY # Blocking-only driver. 1408 1409 If you have neither, you get Fortuna. For most people, 1410 read no further, Fortuna will give a /dev/random that works 1411 like it always used to, and the difference will be irrelevant. 1412 1413 If you remove 'device random', you get *NO* kernel-processed 1414 entropy at all. This may be acceptable to folks building 1415 embedded systems, but has complications. Carry on reading, 1416 and it is assumed you know what you need. 1417 1418 *PLEASE* read random(4) and random(9) if you are in the 1419 habit of tweaking kernel configs, and/or if you are a member 1420 of the embedded community, wanting specific and not-usual 1421 behaviour from your security subsystems. 1422 1423 NOTE!! If you use RANDOM_DUMMY and/or have no 'device 1424 random', you will NOT have a functioning /dev/random, and 1425 many cryptographic features will not work, including SSH. 1426 You may also find strange behaviour from the random(3) set 1427 of library functions, in particular sranddev(3), srandomdev(3) 1428 and arc4random(3). The reason for this is that the KERN_ARND 1429 sysctl only returns entropy if it thinks it has some to 1430 share, and with RANDOM_DUMMY or no 'device random' this 1431 will never happen. 1432 143320150623: 1434 An additional fix for the issue described in the 20150614 sendmail 1435 entry below has been committed in revision 284717. 1436 143720150616: 1438 FreeBSD's old make (fmake) has been removed from the system. It is 1439 available as the devel/fmake port or via pkg install fmake. 1440 144120150615: 1442 The fix for the issue described in the 20150614 sendmail entry 1443 below has been committed in revision 284436. The work 1444 around described in that entry is no longer needed unless the 1445 default setting is overridden by a confDH_PARAMETERS configuration 1446 setting of '5' or pointing to a 512 bit DH parameter file. 1447 144820150614: 1449 ALLOW_DEPRECATED_ATF_TOOLS/ATFFILE support has been removed from 1450 atf.test.mk (included from bsd.test.mk). Please upgrade devel/atf 1451 and devel/kyua to version 0.20+ and adjust any calling code to work 1452 with Kyuafile and kyua. 1453 145420150614: 1455 The import of openssl to address the FreeBSD-SA-15:10.openssl 1456 security advisory includes a change which rejects handshakes 1457 with DH parameters below 768 bits. sendmail releases prior 1458 to 8.15.2 (not yet released), defaulted to a 512 bit 1459 DH parameter setting for client connections. To work around 1460 this interoperability, sendmail can be configured to use a 1461 2048 bit DH parameter by: 1462 1463 1. Edit /etc/mail/`hostname`.mc 1464 2. If a setting for confDH_PARAMETERS does not exist or 1465 exists and is set to a string beginning with '5', 1466 replace it with '2'. 1467 3. If a setting for confDH_PARAMETERS exists and is set to 1468 a file path, create a new file with: 1469 openssl dhparam -out /path/to/file 2048 1470 4. Rebuild the .cf file: 1471 cd /etc/mail/; make; make install 1472 5. Restart sendmail: 1473 cd /etc/mail/; make restart 1474 1475 A sendmail patch is coming, at which time this file will be 1476 updated. 1477 147820150604: 1479 Generation of legacy formatted entries have been disabled by default 1480 in pwd_mkdb(8), as all base system consumers of the legacy formatted 1481 entries were converted to use the new format by default when the new, 1482 machine independent format have been added and supported since FreeBSD 1483 5.x. 1484 1485 Please see the pwd_mkdb(8) manual page for further details. 1486 148720150525: 1488 Clang and llvm have been upgraded to 3.6.1 release. Please see the 1489 20141231 entry below for information about prerequisites and upgrading, 1490 if you are not already using 3.5.0 or higher. 1491 149220150521: 1493 TI platform code switched to using vendor DTS files and this update 1494 may break existing systems running on Beaglebone, Beaglebone Black, 1495 and Pandaboard: 1496 1497 - dtb files should be regenerated/reinstalled. Filenames are the 1498 same but content is different now 1499 - GPIO addressing was changed, now each GPIO bank (32 pins per bank) 1500 has its own /dev/gpiocX device, e.g. pin 121 on /dev/gpioc0 in old 1501 addressing scheme is now pin 25 on /dev/gpioc3. 1502 - Pandaboard: /etc/ttys should be updated, serial console device is 1503 now /dev/ttyu2, not /dev/ttyu0 1504 150520150501: 1506 soelim(1) from gnu/usr.bin/groff has been replaced by usr.bin/soelim. 1507 If you need the GNU extension from groff soelim(1), install groff 1508 from package: pkg install groff, or via ports: textproc/groff. 1509 151020150423: 1511 chmod, chflags, chown and chgrp now affect symlinks in -R mode as 1512 defined in symlink(7); previously symlinks were silently ignored. 1513 151420150415: 1515 The const qualifier has been removed from iconv(3) to comply with 1516 POSIX. The ports tree is aware of this from r384038 onwards. 1517 151820150416: 1519 Libraries specified by LIBADD in Makefiles must have a corresponding 1520 DPADD_<lib> variable to ensure correct dependencies. This is now 1521 enforced in src.libnames.mk. 1522 152320150324: 1524 From legacy ata(4) driver was removed support for SATA controllers 1525 supported by more functional drivers ahci(4), siis(4) and mvs(4). 1526 Kernel modules ataahci and ataadaptec were removed completely, 1527 replaced by ahci and mvs modules respectively. 1528 152920150315: 1530 Clang, llvm and lldb have been upgraded to 3.6.0 release. Please see 1531 the 20141231 entry below for information about prerequisites and 1532 upgrading, if you are not already using 3.5.0 or higher. 1533 153420150307: 1535 The 32-bit PowerPC kernel has been changed to a position-independent 1536 executable. This can only be booted with a version of loader(8) 1537 newer than January 31, 2015, so make sure to update both world and 1538 kernel before rebooting. 1539 154020150217: 1541 If you are running a -CURRENT kernel since r273872 (Oct 30th, 2014), 1542 but before r278950, the RNG was not seeded properly. Immediately 1543 upgrade the kernel to r278950 or later and regenerate any keys (e.g. 1544 ssh keys or openssl keys) that were generated w/ a kernel from that 1545 range. This does not affect programs that directly used /dev/random 1546 or /dev/urandom. All userland uses of arc4random(3) are affected. 1547 154820150210: 1549 The autofs(4) ABI was changed in order to restore binary compatibility 1550 with 10.1-RELEASE. The automountd(8) daemon needs to be rebuilt to work 1551 with the new kernel. 1552 155320150131: 1554 The powerpc64 kernel has been changed to a position-independent 1555 executable. This can only be booted with a new version of loader(8), 1556 so make sure to update both world and kernel before rebooting. 1557 155820150118: 1559 Clang and llvm have been upgraded to 3.5.1 release. This is a bugfix 1560 only release, no new features have been added. Please see the 20141231 1561 entry below for information about prerequisites and upgrading, if you 1562 are not already using 3.5.0. 1563 156420150107: 1565 ELF tools addr2line, elfcopy (strip), nm, size, and strings are now 1566 taken from the ELF Tool Chain project rather than GNU binutils. They 1567 should be drop-in replacements, with the addition of arm64 support. 1568 The WITHOUT_ELFTOOLCHAIN_TOOLS= knob may be used to obtain the 1569 binutils tools, if necessary. See 20150805 for updated information. 1570 157120150105: 1572 The default Unbound configuration now enables remote control 1573 using a local socket. Users who have already enabled the 1574 local_unbound service should regenerate their configuration 1575 by running "service local_unbound setup" as root. 1576 157720150102: 1578 The GNU texinfo and GNU info pages have been removed. 1579 To be able to view GNU info pages please install texinfo from ports. 1580 158120141231: 1582 Clang, llvm and lldb have been upgraded to 3.5.0 release. 1583 1584 As of this release, a prerequisite for building clang, llvm and lldb is 1585 a C++11 capable compiler and C++11 standard library. This means that to 1586 be able to successfully build the cross-tools stage of buildworld, with 1587 clang as the bootstrap compiler, your system compiler or cross compiler 1588 should either be clang 3.3 or later, or gcc 4.8 or later, and your 1589 system C++ library should be libc++, or libdstdc++ from gcc 4.8 or 1590 later. 1591 1592 On any standard FreeBSD 10.x or 11.x installation, where clang and 1593 libc++ are on by default (that is, on x86 or arm), this should work out 1594 of the box. 1595 1596 On 9.x installations where clang is enabled by default, e.g. on x86 and 1597 powerpc, libc++ will not be enabled by default, so libc++ should be 1598 built (with clang) and installed first. If both clang and libc++ are 1599 missing, build clang first, then use it to build libc++. 1600 1601 On 8.x and earlier installations, upgrade to 9.x first, and then follow 1602 the instructions for 9.x above. 1603 1604 Sparc64 and mips users are unaffected, as they still use gcc 4.2.1 by 1605 default, and do not build clang. 1606 1607 Many embedded systems are resource constrained, and will not be able to 1608 build clang in a reasonable time, or in some cases at all. In those 1609 cases, cross building bootable systems on amd64 is a workaround. 1610 1611 This new version of clang introduces a number of new warnings, of which 1612 the following are most likely to appear: 1613 1614 -Wabsolute-value 1615 1616 This warns in two cases, for both C and C++: 1617 * When the code is trying to take the absolute value of an unsigned 1618 quantity, which is effectively a no-op, and almost never what was 1619 intended. The code should be fixed, if at all possible. If you are 1620 sure that the unsigned quantity can be safely cast to signed, without 1621 loss of information or undefined behavior, you can add an explicit 1622 cast, or disable the warning. 1623 1624 * When the code is trying to take an absolute value, but the called 1625 abs() variant is for the wrong type, which can lead to truncation. 1626 If you want to disable the warning instead of fixing the code, please 1627 make sure that truncation will not occur, or it might lead to unwanted 1628 side-effects. 1629 1630 -Wtautological-undefined-compare and 1631 -Wundefined-bool-conversion 1632 1633 These warn when C++ code is trying to compare 'this' against NULL, while 1634 'this' should never be NULL in well-defined C++ code. However, there is 1635 some legacy (pre C++11) code out there, which actively abuses this 1636 feature, which was less strictly defined in previous C++ versions. 1637 1638 Squid and openjdk do this, for example. The warning can be turned off 1639 for C++98 and earlier, but compiling the code in C++11 mode might result 1640 in unexpected behavior; for example, the parts of the program that are 1641 unreachable could be optimized away. 1642 164320141222: 1644 The old NFS client and server (kernel options NFSCLIENT, NFSSERVER) 1645 kernel sources have been removed. The .h files remain, since some 1646 utilities include them. This will need to be fixed later. 1647 If "mount -t oldnfs ..." is attempted, it will fail. 1648 If the "-o" option on mountd(8), nfsd(8) or nfsstat(1) is used, 1649 the utilities will report errors. 1650 165120141121: 1652 The handling of LOCAL_LIB_DIRS has been altered to skip addition of 1653 directories to top level SUBDIR variable when their parent 1654 directory is included in LOCAL_DIRS. Users with build systems with 1655 such hierarchies and without SUBDIR entries in the parent 1656 directory Makefiles should add them or add the directories to 1657 LOCAL_DIRS. 1658 165920141109: 1660 faith(4) and faithd(8) have been removed from the base system. Faith 1661 has been obsolete for a very long time. 1662 166320141104: 1664 vt(4), the new console driver, is enabled by default. It brings 1665 support for Unicode and double-width characters, as well as 1666 support for UEFI and integration with the KMS kernel video 1667 drivers. 1668 1669 You may need to update your console settings in /etc/rc.conf, 1670 most probably the keymap. During boot, /etc/rc.d/syscons will 1671 indicate what you need to do. 1672 1673 vt(4) still has issues and lacks some features compared to 1674 syscons(4). See the wiki for up-to-date information: 1675 https://wiki.freebsd.org/Newcons 1676 1677 If you want to keep using syscons(4), you can do so by adding 1678 the following line to /boot/loader.conf: 1679 kern.vty=sc 1680 168120141102: 1682 pjdfstest has been integrated into kyua as an opt-in test suite. 1683 Please see share/doc/pjdfstest/README for more details on how to 1684 execute it. 1685 168620141009: 1687 gperf has been removed from the base system for architectures 1688 that use clang. Ports that require gperf will obtain it from the 1689 devel/gperf port. 1690 169120140923: 1692 pjdfstest has been moved from tools/regression/pjdfstest to 1693 contrib/pjdfstest . 1694 169520140922: 1696 At svn r271982, The default linux compat kernel ABI has been adjusted 1697 to 2.6.18 in support of the linux-c6 compat ports infrastructure 1698 update. If you wish to continue using the linux-f10 compat ports, 1699 add compat.linux.osrelease=2.6.16 to your local sysctl.conf. Users are 1700 encouraged to update their linux-compat packages to linux-c6 during 1701 their next update cycle. 1702 170320140729: 1704 The ofwfb driver, used to provide a graphics console on PowerPC when 1705 using vt(4), no longer allows mmap() of all physical memory. This 1706 will prevent Xorg on PowerPC with some ATI graphics cards from 1707 initializing properly unless x11-servers/xorg-server is updated to 1708 1.12.4_8 or newer. 1709 171020140723: 1711 The xdev targets have been converted to using TARGET and 1712 TARGET_ARCH instead of XDEV and XDEV_ARCH. 1713 171420140719: 1715 The default unbound configuration has been modified to address 1716 issues with reverse lookups on networks that use private 1717 address ranges. If you use the local_unbound service, run 1718 "service local_unbound setup" as root to regenerate your 1719 configuration, then "service local_unbound reload" to load the 1720 new configuration. 1721 172220140709: 1723 The GNU texinfo and GNU info pages are not built and installed 1724 anymore, WITH_INFO knob has been added to allow to built and install 1725 them again. 1726 UPDATE: see 20150102 entry on texinfo's removal 1727 172820140708: 1729 The GNU readline library is now an INTERNALLIB - that is, it is 1730 statically linked into consumers (GDB and variants) in the base 1731 system, and the shared library is no longer installed. The 1732 devel/readline port is available for third party software that 1733 requires readline. 1734 173520140702: 1736 The Itanium architecture (ia64) has been removed from the list of 1737 known architectures. This is the first step in the removal of the 1738 architecture. 1739 174020140701: 1741 Commit r268115 has added NFSv4.1 server support, merged from 1742 projects/nfsv4.1-server. Since this includes changes to the 1743 internal interfaces between the NFS related modules, a full 1744 build of the kernel and modules will be necessary. 1745 __FreeBSD_version has been bumped. 1746 174720140629: 1748 The WITHOUT_VT_SUPPORT kernel config knob has been renamed 1749 WITHOUT_VT. (The other _SUPPORT knobs have a consistent meaning 1750 which differs from the behaviour controlled by this knob.) 1751 175220140619: 1753 Maximal length of the serial number in CTL was increased from 16 to 1754 64 chars, that breaks ABI. All CTL-related tools, such as ctladm 1755 and ctld, need to be rebuilt to work with a new kernel. 1756 175720140606: 1758 The libatf-c and libatf-c++ major versions were downgraded to 0 and 1759 1 respectively to match the upstream numbers. They were out of 1760 sync because, when they were originally added to FreeBSD, the 1761 upstream versions were not respected. These libraries are private 1762 and not yet built by default, so renumbering them should be a 1763 non-issue. However, unclean source trees will yield broken test 1764 programs once the operator executes "make delete-old-libs" after a 1765 "make installworld". 1766 1767 Additionally, the atf-sh binary was made private by moving it into 1768 /usr/libexec/. Already-built shell test programs will keep the 1769 path to the old binary so they will break after "make delete-old" 1770 is run. 1771 1772 If you are using WITH_TESTS=yes (not the default), wipe the object 1773 tree and rebuild from scratch to prevent spurious test failures. 1774 This is only needed once: the misnumbered libraries and misplaced 1775 binaries have been added to OptionalObsoleteFiles.inc so they will 1776 be removed during a clean upgrade. 1777 177820140512: 1779 Clang and llvm have been upgraded to 3.4.1 release. 1780 178120140508: 1782 We bogusly installed src.opts.mk in /usr/share/mk. This file should 1783 be removed to avoid issues in the future (and has been added to 1784 ObsoleteFiles.inc). 1785 178620140505: 1787 /etc/src.conf now affects only builds of the FreeBSD src tree. In the 1788 past, it affected all builds that used the bsd.*.mk files. The old 1789 behavior was a bug, but people may have relied upon it. To get this 1790 behavior back, you can .include /etc/src.conf from /etc/make.conf 1791 (which is still global and isn't changed). This also changes the 1792 behavior of incremental builds inside the tree of individual 1793 directories. Set MAKESYSPATH to ".../share/mk" to do that. 1794 Although this has survived make universe and some upgrade scenarios, 1795 other upgrade scenarios may have broken. At least one form of 1796 temporary breakage was fixed with MAKESYSPATH settings for buildworld 1797 as well... In cases where MAKESYSPATH isn't working with this 1798 setting, you'll need to set it to the full path to your tree. 1799 1800 One side effect of all this cleaning up is that bsd.compiler.mk 1801 is no longer implicitly included by bsd.own.mk. If you wish to 1802 use COMPILER_TYPE, you must now explicitly include bsd.compiler.mk 1803 as well. 1804 180520140430: 1806 The lindev device has been removed since /dev/full has been made a 1807 standard device. __FreeBSD_version has been bumped. 1808 180920140424: 1810 The knob WITHOUT_VI was added to the base system, which controls 1811 building ex(1), vi(1), etc. Older releases of FreeBSD required ex(1) 1812 in order to reorder files share/termcap and didn't build ex(1) as a 1813 build tool, so building/installing with WITH_VI is highly advised for 1814 build hosts for older releases. 1815 1816 This issue has been fixed in stable/9 and stable/10 in r277022 and 1817 r276991, respectively. 1818 181920140418: 1820 The YES_HESIOD knob has been removed. It has been obsolete for 1821 a decade. Please move to using WITH_HESIOD instead or your builds 1822 will silently lack HESIOD. 1823 182420140405: 1825 The uart(4) driver has been changed with respect to its handling 1826 of the low-level console. Previously the uart(4) driver prevented 1827 any process from changing the baudrate or the CLOCAL and HUPCL 1828 control flags. By removing the restrictions, operators can make 1829 changes to the serial console port without having to reboot. 1830 However, when getty(8) is started on the serial device that is 1831 associated with the low-level console, a misconfigured terminal 1832 line in /etc/ttys will now have a real impact. 1833 Before upgrading the kernel, make sure that /etc/ttys has the 1834 serial console device configured as 3wire without baudrate to 1835 preserve the previous behaviour. E.g: 1836 ttyu0 "/usr/libexec/getty 3wire" vt100 on secure 1837 183820140306: 1839 Support for libwrap (TCP wrappers) in rpcbind was disabled by default 1840 to improve performance. To re-enable it, if needed, run rpcbind 1841 with command line option -W. 1842 184320140226: 1844 Switched back to the GPL dtc compiler due to updates in the upstream 1845 dts files not being supported by the BSDL dtc compiler. You will need 1846 to rebuild your kernel toolchain to pick up the new compiler. Core dumps 1847 may result while building dtb files during a kernel build if you fail 1848 to do so. Set WITHOUT_GPL_DTC if you require the BSDL compiler. 1849 185020140216: 1851 Clang and llvm have been upgraded to 3.4 release. 1852 185320140216: 1854 The nve(4) driver has been removed. Please use the nfe(4) driver 1855 for NVIDIA nForce MCP Ethernet adapters instead. 1856 185720140212: 1858 An ABI incompatibility crept into the libc++ 3.4 import in r261283. 1859 This could cause certain C++ applications using shared libraries built 1860 against the previous version of libc++ to crash. The incompatibility 1861 has now been fixed, but any C++ applications or shared libraries built 1862 between r261283 and r261801 should be recompiled. 1863 186420140204: 1865 OpenSSH will now ignore errors caused by kernel lacking of Capsicum 1866 capability mode support. Please note that enabling the feature in 1867 kernel is still highly recommended. 1868 186920140131: 1870 OpenSSH is now built with sandbox support, and will use sandbox as 1871 the default privilege separation method. This requires Capsicum 1872 capability mode support in kernel. 1873 187420140128: 1875 The libelf and libdwarf libraries have been updated to newer 1876 versions from upstream. Shared library version numbers for 1877 these two libraries were bumped. Any ports or binaries 1878 requiring these two libraries should be recompiled. 1879 __FreeBSD_version is bumped to 1100006. 1880 188120140110: 1882 If a Makefile in a tests/ directory was auto-generating a Kyuafile 1883 instead of providing an explicit one, this would prevent such 1884 Makefile from providing its own Kyuafile in the future during 1885 NO_CLEAN builds. This has been fixed in the Makefiles but manual 1886 intervention is needed to clean an objdir if you use NO_CLEAN: 1887 # find /usr/obj -name Kyuafile | xargs rm -f 1888 188920131213: 1890 The behavior of gss_pseudo_random() for the krb5 mechanism 1891 has changed, for applications requesting a longer random string 1892 than produced by the underlying enctype's pseudo-random() function. 1893 In particular, the random string produced from a session key of 1894 enctype aes256-cts-hmac-sha1-96 or aes256-cts-hmac-sha1-96 will 1895 be different at the 17th octet and later, after this change. 1896 The counter used in the PRF+ construction is now encoded as a 1897 big-endian integer in accordance with RFC 4402. 1898 __FreeBSD_version is bumped to 1100004. 1899 190020131108: 1901 The WITHOUT_ATF build knob has been removed and its functionality 1902 has been subsumed into the more generic WITHOUT_TESTS. If you were 1903 using the former to disable the build of the ATF libraries, you 1904 should change your settings to use the latter. 1905 190620131025: 1907 The default version of mtree is nmtree which is obtained from 1908 NetBSD. The output is generally the same, but may vary 1909 slightly. If you found you need identical output adding 1910 "-F freebsd9" to the command line should do the trick. For the 1911 time being, the old mtree is available as fmtree. 1912 191320131014: 1914 libbsdyml has been renamed to libyaml and moved to /usr/lib/private. 1915 This will break ports-mgmt/pkg. Rebuild the port, or upgrade to pkg 1916 1.1.4_8 and verify bsdyml not linked in, before running "make 1917 delete-old-libs": 1918 # make -C /usr/ports/ports-mgmt/pkg build deinstall install clean 1919 or 1920 # pkg install pkg; ldd /usr/local/sbin/pkg | grep bsdyml 1921 192220131010: 1923 The stable/10 branch has been created in subversion from head 1924 revision r256279. 1925 1926COMMON ITEMS: 1927 1928 General Notes 1929 ------------- 1930 Avoid using make -j when upgrading. While generally safe, there are 1931 sometimes problems using -j to upgrade. If your upgrade fails with 1932 -j, please try again without -j. From time to time in the past there 1933 have been problems using -j with buildworld and/or installworld. This 1934 is especially true when upgrading between "distant" versions (eg one 1935 that cross a major release boundary or several minor releases, or when 1936 several months have passed on the -current branch). 1937 1938 Sometimes, obscure build problems are the result of environment 1939 poisoning. This can happen because the make utility reads its 1940 environment when searching for values for global variables. To run 1941 your build attempts in an "environmental clean room", prefix all make 1942 commands with 'env -i '. See the env(1) manual page for more details. 1943 1944 When upgrading from one major version to another it is generally best to 1945 upgrade to the latest code in the currently installed branch first, then 1946 do an upgrade to the new branch. This is the best-tested upgrade path, 1947 and has the highest probability of being successful. Please try this 1948 approach if you encounter problems with a major version upgrade. Since 1949 the stable 4.x branch point, one has generally been able to upgrade from 1950 anywhere in the most recent stable branch to head / current (or even the 1951 last couple of stable branches). See the top of this file when there's 1952 an exception. 1953 1954 When upgrading a live system, having a root shell around before 1955 installing anything can help undo problems. Not having a root shell 1956 around can lead to problems if pam has changed too much from your 1957 starting point to allow continued authentication after the upgrade. 1958 1959 This file should be read as a log of events. When a later event changes 1960 information of a prior event, the prior event should not be deleted. 1961 Instead, a pointer to the entry with the new information should be 1962 placed in the old entry. Readers of this file should also sanity check 1963 older entries before relying on them blindly. Authors of new entries 1964 should write them with this in mind. 1965 1966 ZFS notes 1967 --------- 1968 When upgrading the boot ZFS pool to a new version, always follow 1969 these two steps: 1970 1971 1.) recompile and reinstall the ZFS boot loader and boot block 1972 (this is part of "make buildworld" and "make installworld") 1973 1974 2.) update the ZFS boot block on your boot drive 1975 1976 The following example updates the ZFS boot block on the first 1977 partition (freebsd-boot) of a GPT partitioned drive ada0: 1978 "gpart bootcode -p /boot/gptzfsboot -i 1 ada0" 1979 1980 Non-boot pools do not need these updates. 1981 1982 To build a kernel 1983 ----------------- 1984 If you are updating from a prior version of FreeBSD (even one just 1985 a few days old), you should follow this procedure. It is the most 1986 failsafe as it uses a /usr/obj tree with a fresh mini-buildworld, 1987 1988 make kernel-toolchain 1989 make -DALWAYS_CHECK_MAKE buildkernel KERNCONF=YOUR_KERNEL_HERE 1990 make -DALWAYS_CHECK_MAKE installkernel KERNCONF=YOUR_KERNEL_HERE 1991 1992 To test a kernel once 1993 --------------------- 1994 If you just want to boot a kernel once (because you are not sure 1995 if it works, or if you want to boot a known bad kernel to provide 1996 debugging information) run 1997 make installkernel KERNCONF=YOUR_KERNEL_HERE KODIR=/boot/testkernel 1998 nextboot -k testkernel 1999 2000 To rebuild everything and install it on the current system. 2001 ----------------------------------------------------------- 2002 # Note: sometimes if you are running current you gotta do more than 2003 # is listed here if you are upgrading from a really old current. 2004 2005 <make sure you have good level 0 dumps> 2006 make buildworld 2007 make buildkernel KERNCONF=YOUR_KERNEL_HERE 2008 make installkernel KERNCONF=YOUR_KERNEL_HERE 2009 [1] 2010 <reboot in single user> [3] 2011 mergemaster -Fp [5] 2012 make installworld 2013 mergemaster -Fi [4] 2014 make delete-old [6] 2015 <reboot> 2016 2017 To cross-install current onto a separate partition 2018 -------------------------------------------------- 2019 # In this approach we use a separate partition to hold 2020 # current's root, 'usr', and 'var' directories. A partition 2021 # holding "/", "/usr" and "/var" should be about 2GB in 2022 # size. 2023 2024 <make sure you have good level 0 dumps> 2025 <boot into -stable> 2026 make buildworld 2027 make buildkernel KERNCONF=YOUR_KERNEL_HERE 2028 <maybe newfs current's root partition> 2029 <mount current's root partition on directory ${CURRENT_ROOT}> 2030 make installworld DESTDIR=${CURRENT_ROOT} -DDB_FROM_SRC 2031 make distribution DESTDIR=${CURRENT_ROOT} # if newfs'd 2032 make installkernel KERNCONF=YOUR_KERNEL_HERE DESTDIR=${CURRENT_ROOT} 2033 cp /etc/fstab ${CURRENT_ROOT}/etc/fstab # if newfs'd 2034 <edit ${CURRENT_ROOT}/etc/fstab to mount "/" from the correct partition> 2035 <reboot into current> 2036 <do a "native" rebuild/install as described in the previous section> 2037 <maybe install compatibility libraries from ports/misc/compat*> 2038 <reboot> 2039 2040 2041 To upgrade in-place from stable to current 2042 ---------------------------------------------- 2043 <make sure you have good level 0 dumps> 2044 make buildworld [9] 2045 make buildkernel KERNCONF=YOUR_KERNEL_HERE [8] 2046 make installkernel KERNCONF=YOUR_KERNEL_HERE 2047 [1] 2048 <reboot in single user> [3] 2049 mergemaster -Fp [5] 2050 make installworld 2051 mergemaster -Fi [4] 2052 make delete-old [6] 2053 <reboot> 2054 2055 Make sure that you've read the UPDATING file to understand the 2056 tweaks to various things you need. At this point in the life 2057 cycle of current, things change often and you are on your own 2058 to cope. The defaults can also change, so please read ALL of 2059 the UPDATING entries. 2060 2061 Also, if you are tracking -current, you must be subscribed to 2062 freebsd-current@freebsd.org. Make sure that before you update 2063 your sources that you have read and understood all the recent 2064 messages there. If in doubt, please track -stable which has 2065 much fewer pitfalls. 2066 2067 [1] If you have third party modules, such as vmware, you 2068 should disable them at this point so they don't crash your 2069 system on reboot. 2070 2071 [3] From the bootblocks, boot -s, and then do 2072 fsck -p 2073 mount -u / 2074 mount -a 2075 sh /etc/rc.d/zfs start # mount zfs filesystem, if needed 2076 cd src # full path to source 2077 adjkerntz -i # if CMOS is wall time 2078 Also, when doing a major release upgrade, it is required that 2079 you boot into single user mode to do the installworld. 2080 2081 [4] Note: This step is non-optional. Failure to do this step 2082 can result in a significant reduction in the functionality of the 2083 system. Attempting to do it by hand is not recommended and those 2084 that pursue this avenue should read this file carefully, as well 2085 as the archives of freebsd-current and freebsd-hackers mailing lists 2086 for potential gotchas. The -U option is also useful to consider. 2087 See mergemaster(8) for more information. 2088 2089 [5] Usually this step is a no-op. However, from time to time 2090 you may need to do this if you get unknown user in the following 2091 step. It never hurts to do it all the time. You may need to 2092 install a new mergemaster (cd src/usr.sbin/mergemaster && make 2093 install) after the buildworld before this step if you last updated 2094 from current before 20130425 or from -stable before 20130430. 2095 2096 [6] This only deletes old files and directories. Old libraries 2097 can be deleted by "make delete-old-libs", but you have to make 2098 sure that no program is using those libraries anymore. 2099 2100 [8] The new kernel must be able to run existing binaries used by an 2101 installworld. When upgrading across major versions, the new kernel's 2102 configuration must include the correct COMPAT_FREEBSD<n> option for 2103 existing binaries (e.g. COMPAT_FREEBSD11 to run 11.x binaries). Failure 2104 to do so may leave you with a system that is hard to boot to recover. A 2105 GENERIC kernel will include suitable compatibility options to run 2106 binaries from older branches. Note that the ability to run binaries 2107 from unsupported branches is not guaranteed. 2108 2109 Make sure that you merge any new devices from GENERIC since the 2110 last time you updated your kernel config file. Options also 2111 change over time, so you may need to adjust your custom kernels 2112 for these as well. 2113 2114 [9] If CPUTYPE is defined in your /etc/make.conf, make sure to use the 2115 "?=" instead of the "=" assignment operator, so that buildworld can 2116 override the CPUTYPE if it needs to. 2117 2118 MAKEOBJDIRPREFIX must be defined in an environment variable, and 2119 not on the command line, or in /etc/make.conf. buildworld will 2120 warn if it is improperly defined. 2121FORMAT: 2122 2123This file contains a list, in reverse chronological order, of major 2124breakages in tracking -current. It is not guaranteed to be a complete 2125list of such breakages, and only contains entries since September 23, 2011. 2126If you need to see UPDATING entries from before that date, you will need 2127to fetch an UPDATING file from an older FreeBSD release. 2128 2129Copyright information: 2130 2131Copyright 1998-2009 M.
