1 Updating Information for FreeBSD current users. 2 3This file is maintained and copyrighted by M. Warner Losh <imp@freebsd.org>. 4See end of file for further details. For commonly done items, please see the 5COMMON ITEMS: section later in the file. These instructions assume that you 6basically know what you are doing. If not, then please consult the FreeBSD 7handbook: 8 9 https://www.freebsd.org/doc/en_US.ISO8859-1/books/handbook/makeworld.html 10 11Items affecting the ports and packages system can be found in 12/usr/ports/UPDATING. Please read that file before running portupgrade. 13 14NOTE TO PEOPLE WHO THINK THAT FreeBSD 13.x IS SLOW: 15 FreeBSD 13.x has many debugging features turned on, in both the kernel 16 and userland. These features attempt to detect incorrect use of 17 system primitives, and encourage loud failure through extra sanity 18 checking and fail stop semantics. They also substantially impact 19 system performance. If you want to do performance measurement, 20 benchmarking, and optimization, you'll want to turn them off. This 21 includes various WITNESS- related kernel options, INVARIANTS, malloc 22 debugging flags in userland, and various verbose features in the 23 kernel. Many developers choose to disable these features on build 24 machines to maximize performance. (To completely disable malloc 25 debugging, define MALLOC_PRODUCTION in /etc/make.conf, or to merely 26 disable the most expensive debugging functionality run 27 "ln -s 'abort:false,junk:false' /etc/malloc.conf".) 28 2920191212: 30 r355677 has modified the internal interface used between the 31 NFS modules in the kernel. As such, they must all be upgraded 32 simultaneously. I will do a version bump for this. 33 3420191205: 35 The root certificates of the Mozilla CA Certificate Store have been 36 imported into the base system and can be managed with the certctl(8) 37 utility. If you have installed the security/ca_root_nss port or package 38 with the ETCSYMLINK option (the default), be advised that there may be 39 differences between those included in the port and those included in 40 base due to differences in nss branch used as well as general update 41 frequency. Note also that certctl(8) cannot manage certs in the 42 format used by the security/ca_root_nss port. 43 4420191120: 45 The amd(8) automount daemon has been disabled by default, and will be 46 removed in the future. As of FreeBSD 10.1 the autofs(5) is available 47 for automounting. 48 4920191107: 50 The nctgpio and wbwd drivers have been moved to the superio bus. 51 If you have one of these drivers in a kernel configuration, then 52 you should add device superio to it. If you use one of these drivers 53 as a module and you compile a custom set of modules, then you should 54 add superio to the set. 55 5620191021: 57 KPIs for network drivers to access interface addresses have changed. 58 Users need to recompile NIC driver modules together with kernel. 59 6020191021: 61 The net.link.tap.user_open sysctl no longer prevents user opening of 62 already created /dev/tapNN devices. Access is still controlled by 63 node permissions, just like tun devices. The net.link.tap.user_open 64 sysctl is now used only to allow users to perform devfs cloning of 65 tap devices, and the subsequent open may not succeed if the user is not 66 in the appropriate group. This sysctl may be deprecated/removed 67 completely in the future. 68 6920191009: 70 mips, powerpc, and sparc64 are no longer built as part of 71 universe / tinderbox unless MAKE_OBSOLETE_GCC is defined. If 72 not defined, mips, powerpc, and sparc64 builds will look for 73 the xtoolchain binaries and if installed use them for universe 74 builds. As llvm 9.0 becomes vetted for these architectures, they 75 will be removed from the list. 76 7720191009: 78 Clang, llvm, lld, lldb, compiler-rt, libc++, libunwind and openmp have 79 been upgraded to 9.0.0. Please see the 20141231 entry below for 80 information about prerequisites and upgrading, if you are not already 81 using clang 3.5.0 or higher. 82 8320191003: 84 The hpt27xx, hptmv, hptnr, and hptrr drivers have been removed from 85 GENERIC. They are available as modules and can be loaded by adding 86 to /boot/loader.conf hpt27xx_load="YES", hptmv_load="YES", 87 hptnr_load="YES", or hptrr_load="YES", respectively. 88 8920190913: 90 ntpd no longer by default locks its pages in memory, allowing them 91 to be paged out by the kernel. Use rlimit memlock to restore 92 historic BSD behaviour. For example, add "rlimit memlock 32" 93 to ntp.conf to lock up to 32 MB of ntpd address space in memory. 94 9520190823: 96 Several of ping6's options have been renamed for better consistency 97 with ping. If you use any of -ARWXaghmrtwx, you must update your 98 scripts. See ping6(8) for details. 99 10020190727: 101 The vfs.fusefs.sync_unmount and vfs.fusefs.init_backgrounded sysctls 102 and the "-o sync_unmount" and "-o init_backgrounded" mount options have 103 been removed from mount_fusefs(8). You can safely remove them from 104 your scripts, because they had no effect. 105 106 The vfs.fusefs.fix_broken_io, vfs.fusefs.sync_resize, 107 vfs.fusefs.refresh_size, vfs.fusefs.mmap_enable, 108 vfs.fusefs.reclaim_revoked, and vfs.fusefs.data_cache_invalidate 109 sysctls have been removed. If you felt the need to set any of them to 110 a non-default value, please tell asomers@FreeBSD.org why. 111 11220190713: 113 Default permissions on the /var/account/acct file (and copies of it 114 rotated by periodic daily scripts) are changed from 0644 to 0640 115 because the file contains sensitive information that should not be 116 world-readable. If the /var/account directory must be created by 117 rc.d/accounting, the mode used is now 0750. Admins who use the 118 accounting feature are encouraged to change the mode of an existing 119 /var/account directory to 0750 or 0700. 120 12120190620: 122 Entropy collection and the /dev/random device are no longer optional 123 components. The "device random" option has been removed. 124 Implementations of distilling algorithms can still be made loadable 125 with "options RANDOM_LOADABLE" (e.g., random_fortuna.ko). 126 12720190612: 128 Clang, llvm, lld, lldb, compiler-rt, libc++, libunwind and openmp have 129 been upgraded to 8.0.1. Please see the 20141231 entry below for 130 information about prerequisites and upgrading, if you are not already 131 using clang 3.5.0 or higher. 132 13320190608: 134 A fix was applied to i386 kernel modules to avoid panics with 135 dpcpu or vnet. Users need to recompile i386 kernel modules 136 having pcpu or vnet sections or they will refuse to load. 137 13820190513: 139 User-wired pages now have their own counter, 140 vm.stats.vm.v_user_wire_count. The vm.max_wired sysctl was renamed 141 to vm.max_user_wired and changed from an unsigned int to an unsigned 142 long. bhyve VMs wired with the -S are now subject to the user 143 wiring limit; the vm.max_user_wired sysctl may need to be tuned to 144 avoid running into the limit. 145 14620190507: 147 The IPSEC option has been removed from GENERIC. Users requiring 148 ipsec(4) must now load the ipsec(4) kernel module. 149 15020190507: 151 The tap(4) driver has been folded into tun(4), and the module has been 152 renamed to tuntap. You should update any kld_list="if_tap" or 153 kld_list="if_tun" entries in /etc/rc.conf, if_tap_load="YES" or 154 if_tun_load="YES" entries in /boot/loader.conf to load the if_tuntap 155 module instead, and "device tap" or "device tun" entries in kernel 156 config files to select the tuntap device instead. 157 15820190418: 159 The following knobs have been added related to tradeoffs between 160 safe use of the random device and availability in the absence of 161 entropy: 162 163 kern.random.initial_seeding.bypass_before_seeding: tunable; set 164 non-zero to bypass the random device prior to seeding, or zero to 165 block random requests until the random device is initially seeded. 166 For now, set to 1 (unsafe) by default to restore pre-r346250 boot 167 availability properties. 168 169 kern.random.initial_seeding.read_random_bypassed_before_seeding: 170 read-only diagnostic sysctl that is set when bypass is enabled and 171 read_random(9) is bypassed, to enable programmatic handling of this 172 initial condition, if desired. 173 174 kern.random.initial_seeding.arc4random_bypassed_before_seeding: 175 Similar to the above, but for for arc4random(9) initial seeding. 176 177 kern.random.initial_seeding.disable_bypass_warnings: tunable; set 178 non-zero to disable warnings in dmesg when the same conditions are 179 met as for the diagnostic sysctls above. Defaults to zero, i.e., 180 produce warnings in dmesg when the conditions are met. 181 18220190416: 183 The loadable random module KPI has changed; the random_infra_init() 184 routine now requires a 3rd function pointer for a bool (*)(void) 185 method that returns true if the random device is seeded (and 186 therefore unblocked). 187 18820190404: 189 r345895 reverts r320698. This implies that an nfsuserd(8) daemon 190 built from head sources between r320757 (July 6, 2017) and 191 r338192 (Aug. 22, 2018) will not work unless the "-use-udpsock" 192 is added to the command line. 193 nfsuserd daemons built from head sources that are post-r338192 are 194 not affected and should continue to work. 195 19620190320: 197 The fuse(4) module has been renamed to fusefs(4) for consistency with 198 other filesystems. You should update any kld_load="fuse" entries in 199 /etc/rc.conf, fuse_load="YES" entries in /boot/loader.conf, and 200 "options FUSE" entries in kernel config files. 201 20220190304: 203 Clang, llvm, lld, lldb, compiler-rt and libc++ have been upgraded to 204 8.0.0. Please see the 20141231 entry below for information about 205 prerequisites and upgrading, if you are not already using clang 3.5.0 206 or higher. 207 20820190226: 209 geom_uzip(4) depends on the new module xz. If geom_uzip is statically 210 compiled into your custom kernel, add 'device xz' statement to the 211 kernel config. 212 21320190219: 214 drm and drm2 have been removed from the tree. Please see 215 https://wiki.freebsd.org/Graphics for the latest information on 216 migrating to the drm ports. 217 21820190131: 219 Iflib is no longer unconditionally compiled into the kernel. Drivers 220 using iflib and statically compiled into the kernel, now require 221 the 'device iflib' config option. For the same drivers loaded as 222 modules on kernels not having 'device iflib', the iflib.ko module 223 is loaded automatically. 224 22520190125: 226 The IEEE80211_AMPDU_AGE and AH_SUPPORT_AR5416 kernel configuration 227 options no longer exist since r343219 and r343427 respectively; 228 nothing uses them, so they should be just removed from custom 229 kernel config files. 230 23120181230: 232 r342635 changes the way efibootmgr(8) works by requiring users to add 233 the -b (bootnum) parameter for commands where the bootnum was previously 234 specified with each option. For example 'efibootmgr -B 0001' is now 235 'efibootmgr -B -b 0001'. 236 23720181220: 238 r342286 modifies the NFSv4 server so that it obeys vfs.nfsd.nfs_privport 239 in the same as it is applied to NFSv2 and 3. This implies that NFSv4 240 servers that have vfs.nfsd.nfs_privport set will only allow mounts 241 from clients using a reserved port#. Since both the FreeBSD and Linux 242 NFSv4 clients use reserved port#s by default, this should not affect 243 most NFSv4 mounts. 244 24520181219: 246 The XLP config has been removed. We can't support 64-bit atomics in this 247 kernel because it is running in 32-bit mode. XLP users must transition 248 to running a 64-bit kernel (XLP64 or XLPN32). 249 250 The mips GXEMUL support has been removed from FreeBSD. MALTA* + qemu is 251 the preferred emulator today and we don't need two different ones. 252 253 The old sibyte / swarm / Broadcom BCM1250 support has been 254 removed from the mips port. 255 25620181211: 257 Clang, llvm, lld, lldb, compiler-rt and libc++ have been upgraded to 258 7.0.1. Please see the 20141231 entry below for information about 259 prerequisites and upgrading, if you are not already using clang 3.5.0 260 or higher. 261 26220181211: 263 Remove the timed and netdate programs from the base tree. Setting 264 the time with these daemons has been obsolete for over a decade. 265 26620181126: 267 On amd64, arm64 and armv7 (architectures that install LLVM's ld.lld 268 linker as /usr/bin/ld) GNU ld is no longer installed as ld.bfd, as 269 it produces broken binaries when ifuncs are in use. Users needing 270 GNU ld should install the binutils port or package. 271 27220181123: 273 The BSD crtbegin and crtend code has been enabled by default. It has 274 had extensive testing on amd64, arm64, and i386. It can be disabled 275 by building a world with -DWITHOUT_BSD_CRTBEGIN. 276 27720181115: 278 The set of CTM commands (ctm, ctm_smail, ctm_rmail, ctm_dequeue) 279 has been converted to a port (misc/ctm) and will be removed from 280 FreeBSD-13. It is available as a package (ctm) for all supported 281 FreeBSD versions. 282 28320181110: 284 The default newsyslog.conf(5) file has been changed to only include 285 files in /etc/newsyslog.conf.d/ and /usr/local/etc/newsyslog.conf.d/ if 286 the filenames end in '.conf' and do not begin with a '.'. 287 288 You should check the configuration files in these two directories match 289 this naming convention. You can verify which configuration files are 290 being included using the command: 291 $ newsyslog -Nrv 292 29320181015: 294 Ports for the DRM modules have been simplified. Now, amd64 users should 295 just install the drm-kmod port. All others should install 296 drm-legacy-kmod. 297 298 Graphics hardware that's newer than about 2010 usually works with 299 drm-kmod. For hardware older than 2013, however, some users will need 300 to use drm-legacy-kmod if drm-kmod doesn't work for them. Hardware older 301 than 2008 usually only works in drm-legacy-kmod. The graphics team can 302 only commit to hardware made since 2013 due to the complexity of the 303 market and difficulty to test all the older cards effectively. If you 304 have hardware supported by drm-kmod, you are strongly encouraged to use 305 that as you will get better support. 306 307 Other than KPI chasing, drm-legacy-kmod will not be updated. As outlined 308 elsewhere, the drm and drm2 modules will be eliminated from the src base 309 soon (with a limited exception for arm). Please update to the package 310 asap and report any issues to x11@freebsd.org. 311 312 Generally, anybody using the drm*-kmod packages should add 313 WITHOUT_DRM_MODULE=t and WITHOUT_DRM2_MODULE=t to avoid nasty 314 cross-threading surprises, especially with automatic driver 315 loading from X11 startup. These will become the defaults in 13-current 316 shortly. 317 31820181012: 319 The ixlv(4) driver has been renamed to iavf(4). As a consequence, 320 custom kernel and module loading configuration files must be updated 321 accordingly. Moreover, interfaces previous presented as ixlvN to the 322 system are now exposed as iavfN and network configuration files must 323 be adjusted as necessary. 324 32520181009: 326 OpenSSL has been updated to version 1.1.1. This update included 327 additional various API changes throughout the base system. It is 328 important to rebuild third-party software after upgrading. The value 329 of __FreeBSD_version has been bumped accordingly. 330 33120181006: 332 The legacy DRM modules and drivers have now been added to the loader's 333 module blacklist, in favor of loading them with kld_list in rc.conf(5). 334 The module blacklist may be overridden with the loader.conf(5) 335 'module_blacklist' variable, but loading them via rc.conf(5) is strongly 336 encouraged. 337 33820181002: 339 The cam(4) based nda(4) driver will be used over nvd(4) by default on 340 powerpc64. You may set 'options NVME_USE_NVD=1' in your kernel conf or 341 loader tunable 'hw.nvme.use_nvd=1' if you wish to use the existing 342 driver. Make sure to edit /boot/etc/kboot.conf and fstab to use the 343 nda device name. 344 34520180913: 346 Reproducible build mode is now on by default, in preparation for 347 FreeBSD 12.0. This eliminates build metadata such as the user, 348 host, and time from the kernel (and uname), unless the working tree 349 corresponds to a modified checkout from a version control system. 350 The previous behavior can be obtained by setting the /etc/src.conf 351 knob WITHOUT_REPRODUCIBLE_BUILD. 352 35320180826: 354 The Yarrow CSPRNG has been removed from the kernel as it has not been 355 supported by its designers since at least 2003. Fortuna has been the 356 default since FreeBSD-11. 357 35820180822: 359 devctl freeze/thaw have gone into the tree, the rc scripts have been 360 updated to use them and devmatch has been changed. You should update 361 kernel, userland and rc scripts all at the same time. 362 36320180818: 364 The default interpreter has been switched from 4th to Lua. 365 LOADER_DEFAULT_INTERP, documented in build(7), will override the default 366 interpreter. If you have custom FORTH code you will need to set 367 LOADER_DEFAULT_INTERP=4th (valid values are 4th, lua or simp) in 368 src.conf for the build. This will create default hard links between 369 loader and loader_4th instead of loader and loader_lua, the new default. 370 If you are using UEFI it will create the proper hard link to loader.efi. 371 372 bhyve uses userboot.so. It remains 4th-only until some issues are solved 373 regarding coexisting with multiple versions of FreeBSD are resolved. 374 37520180815: 376 ls(1) now respects the COLORTERM environment variable used in other 377 systems and software to indicate that a colored terminal is both 378 supported and desired. If ls(1) is suddenly emitting colors, they may 379 be disabled again by either removing the unwanted COLORTERM from your 380 environment, or using `ls --color=never`. The ls(1) specific CLICOLOR 381 may not be observed in a future release. 382 38320180808: 384 The default pager for most commands has been changed to "less". To 385 restore the old behavior, set PAGER="more" and MANPAGER="more -s" in 386 your environment. 387 38820180731: 389 The jedec_ts(4) driver has been removed. A superset of its functionality 390 is available in the jedec_dimm(4) driver, and the manpage for that 391 driver includes migration instructions. If you have "device jedec_ts" 392 in your kernel configuration file, it must be removed. 393 39420180730: 395 amd64/GENERIC now has EFI runtime services, EFIRT, enabled by default. 396 This should have no effect if the kernel is booted via BIOS/legacy boot. 397 EFIRT may be disabled via a loader tunable, efi.rt.disabled, if a system 398 has a buggy firmware that prevents a successful boot due to use of 399 runtime services. 400 40120180727: 402 Atmel AT91RM9200 and AT91SAM9, Cavium CNS 11xx and XScale 403 support has been removed from the tree. These ports were 404 obsolete and/or known to be broken for many years. 405 40620180723: 407 loader.efi has been augmented to participate more fully in the 408 UEFI boot manager protocol. loader.efi will now look at the 409 BootXXXX environment variable to determine if a specific kernel 410 or root partition was specified. XXXX is derived from BootCurrent. 411 efibootmgr(8) manages these standard UEFI variables. 412 41320180720: 414 zfsloader's functionality has now been folded into loader. 415 zfsloader is no longer necessary once you've updated your 416 boot blocks. For a transition period, we will install a 417 hardlink for zfsloader to loader to allow a smooth transition 418 until the boot blocks can be updated (hard link because old 419 zfs boot blocks don't understand symlinks). 420 42120180719: 422 ARM64 now have efifb support, if you want to have serial console 423 on your arm64 board when an screen is connected and the bootloader 424 setup a frame buffer for us to use, just add : 425 boot_serial=YES 426 boot_multicons=YES 427 in /boot/loader.conf 428 For Raspberry Pi 3 (RPI) users, this is needed even if you don't have 429 an screen connected as the firmware will setup a frame buffer are that 430 u-boot will expose as an EFI frame buffer. 431 43220180719: 433 New uid:gid added, ntpd:ntpd (123:123). Be sure to run mergemaster 434 or take steps to update /etc/passwd before doing installworld on 435 existing systems. Do not skip the "mergemaster -Fp" step before 436 installworld, as described in the update procedures near the bottom 437 of this document. Also, rc.d/ntpd now starts ntpd(8) as user ntpd 438 if the new mac_ntpd(4) policy is available, unless ntpd_flags or 439 the ntp config file contain options that change file/dir locations. 440 When such options (e.g., "statsdir" or "crypto") are used, ntpd can 441 still be run as non-root by setting ntpd_user=ntpd in rc.conf, after 442 taking steps to ensure that all required files/dirs are accessible 443 by the ntpd user. 444 44520180717: 446 Big endian arm support has been removed. 447 44820180711: 449 The static environment setup in kernel configs is no longer mutually 450 exclusive with the loader(8) environment by default. In order to 451 restore the previous default behavior of disabling the loader(8) 452 environment if a static environment is present, you must specify 453 loader_env.disabled=1 in the static environment. 454 45520180705: 456 The ABI of syscalls used by management tools like sockstat and 457 netstat has been broken to allow 32-bit binaries to work on 458 64-bit kernels without modification. These programs will need 459 to match the kernel in order to function. External programs may 460 require minor modifications to accommodate a change of type in 461 structures from pointers to 64-bit virtual addresses. 462 46320180702: 464 On i386 and amd64 atomics are now inlined. Out of tree modules using 465 atomics will need to be rebuilt. 466 46720180701: 468 The '%I' format in the kern.corefile sysctl limits the number of 469 core files that a process can generate to the number stored in the 470 debug.ncores sysctl. The '%I' format is replaced by the single digit 471 index. Previously, if all indexes were taken the kernel would overwrite 472 only a core file with the highest index in a filename. 473 Currently the system will create a new core file if there is a free 474 index or if all slots are taken it will overwrite the oldest one. 475 47620180630: 477 Clang, llvm, lld, lldb, compiler-rt and libc++ have been upgraded to 478 6.0.1. Please see the 20141231 entry below for information about 479 prerequisites and upgrading, if you are not already using clang 3.5.0 480 or higher. 481 48220180628: 483 r335753 introduced a new quoting method. However, etc/devd/devmatch.conf 484 needed to be changed to work with it. This change was made with r335763 485 and requires a mergemaster / etcupdate / etc to update the installed 486 file. 487 48820180612: 489 r334930 changed the interface between the NFS modules, so they all 490 need to be rebuilt. r335018 did a __FreeBSD_version bump for this. 491 49220180530: 493 As of r334391 lld is the default amd64 system linker; it is installed 494 as /usr/bin/ld. Kernel build workarounds (see 20180510 entry) are no 495 longer necessary. 496 49720180530: 498 The kernel / userland interface for devinfo changed, so you'll 499 need a new kernel and userland as a pair for it to work (rebuilding 500 lib/libdevinfo is all that's required). devinfo and devmatch will 501 not work, but everything else will when there's a mismatch. 502 50320180523: 504 The on-disk format for hwpmc callchain records has changed to include 505 threadid corresponding to a given record. This changes the field offsets 506 and thus requires that libpmcstat be rebuilt before using a kernel 507 later than r334108. 508 50920180517: 510 The vxge(4) driver has been removed. This driver was introduced into 511 HEAD one week before the Exar left the Ethernet market and is not 512 known to be used. If you have device vxge in your kernel config file 513 it must be removed. 514 51520180510: 516 The amd64 kernel now requires a ld that supports ifunc to produce a 517 working kernel, either lld or a newer binutils. lld is built by default 518 on amd64, and the 'buildkernel' target uses it automatically. However, 519 it is not the default linker, so building the kernel the traditional 520 way requires LD=ld.lld on the command line (or LD=/usr/local/bin/ld for 521 binutils port/package). lld will soon be default, and this requirement 522 will go away. 523 524 NOTE: As of r334391 lld is the default system linker on amd64, and no 525 workaround is necessary. 526 52720180508: 528 The nxge(4) driver has been removed. This driver was for PCI-X 10g 529 cards made by s2io/Neterion. The company was acquired by Exar and 530 no longer sells or supports Ethernet products. If you have device 531 nxge in your kernel config file it must be removed. 532 53320180504: 534 The tz database (tzdb) has been updated to 2018e. This version more 535 correctly models time stamps in time zones with negative DST such as 536 Europe/Dublin (from 1971 on), Europe/Prague (1946/7), and 537 Africa/Windhoek (1994/2017). This does not affect the UT offsets, only 538 time zone abbreviations and the tm_isdst flag. 539 54020180502: 541 The ixgb(4) driver has been removed. This driver was for an early and 542 uncommon legacy PCI 10GbE for a single ASIC, Intel 82597EX. Intel 543 quickly shifted to the long lived ixgbe family. If you have device 544 ixgb in your kernel config file it must be removed. 545 54620180501: 547 The lmc(4) driver has been removed. This was a WAN interface 548 card that was already reportedly rare in 2003, and had an ambiguous 549 license. If you have device lmc in your kernel config file it must 550 be removed. 551 55220180413: 553 Support for Arcnet networks has been removed. If you have device 554 arcnet or device cm in your kernel config file they must be 555 removed. 556 55720180411: 558 Support for FDDI networks has been removed. If you have device 559 fddi or device fpa in your kernel config file they must be 560 removed. 561 56220180406: 563 In addition to supporting RFC 3164 formatted messages, the 564 syslogd(8) service is now capable of parsing RFC 5424 formatted 565 log messages. The main benefit of using RFC 5424 is that clients 566 may now send log messages with timestamps containing year numbers, 567 microseconds and time zone offsets. 568 569 Similarly, the syslog(3) C library function has been altered to 570 send RFC 5424 formatted messages to the local system logging 571 daemon. On systems using syslogd(8), this change should have no 572 negative impact, as long as syslogd(8) and the C library are 573 updated at the same time. On systems using a different system 574 logging daemon, it may be necessary to make configuration 575 adjustments, depending on the software used. 576 577 When using syslog-ng, add the 'syslog-protocol' flag to local 578 input sources to enable parsing of RFC 5424 formatted messages: 579 580 source src { 581 unix-dgram("/var/run/log" flags(syslog-protocol)); 582 } 583 584 When using rsyslog, disable the 'SysSock.UseSpecialParser' option 585 of the 'imuxsock' module to let messages be processed by the 586 regular RFC 3164/5424 parsing pipeline: 587 588 module(load="imuxsock" SysSock.UseSpecialParser="off") 589 590 Do note that these changes only affect communication between local 591 applications and syslogd(8). The format that syslogd(8) uses to 592 store messages on disk or forward messages to other systems 593 remains unchanged. syslogd(8) still uses RFC 3164 for these 594 purposes. Options to customize this behaviour will be added in the 595 future. Utilities that process log files stored in /var/log are 596 thus expected to continue to function as before. 597 598 __FreeBSD_version has been incremented to 1200061 to denote this 599 change. 600 60120180328: 602 Support for token ring networks has been removed. If you 603 have "device token" in your kernel config you should remove 604 it. No device drivers supported token ring. 605 60620180323: 607 makefs was modified to be able to tag ISO9660 El Torito boot catalog 608 entries as EFI instead of overloading the i386 tag as done previously. 609 The amd64 mkisoimages.sh script used to build amd64 ISO images for 610 release was updated to use this. This may mean that makefs must be 611 updated before "make cdrom" can be run in the release directory. This 612 should be as simple as: 613 614 $ cd $SRCDIR/usr.sbin/makefs 615 $ make depend all install 616 61720180212: 618 FreeBSD boot loader enhanced with Lua scripting. It's purely opt-in for 619 now by building WITH_LOADER_LUA and WITHOUT_FORTH in /etc/src.conf. 620 Co-existence for the transition period will come shortly. Booting is a 621 complex environment and test coverage for Lua-enabled loaders has been 622 thin, so it would be prudent to assume it might not work and make 623 provisions for backup boot methods. 624 62520180211: 626 devmatch functionality has been turned on in devd. It will automatically 627 load drivers for unattached devices. This may cause unexpected drivers 628 to be loaded. Please report any problems to current@ and 629 imp@freebsd.org. 630 63120180114: 632 Clang, llvm, lld, lldb, compiler-rt and libc++ have been upgraded to 633 6.0.0. Please see the 20141231 entry below for information about 634 prerequisites and upgrading, if you are not already using clang 3.5.0 635 or higher. 636 63720180110: 638 LLVM's lld linker is now used as the FreeBSD/amd64 bootstrap linker. 639 This means it is used to link the kernel and userland libraries and 640 executables, but is not yet installed as /usr/bin/ld by default. 641 642 To revert to ld.bfd as the bootstrap linker, in /etc/src.conf set 643 WITHOUT_LLD_BOOTSTRAP=yes 644 64520180110: 646 On i386, pmtimer has been removed. Its functionality has been folded 647 into apm. It was a no-op on ACPI in current for a while now (but was 648 still needed on i386 in FreeBSD 11 and earlier). Users may need to 649 remove it from kernel config files. 650 65120180104: 652 The use of RSS hash from the network card aka flowid has been 653 disabled by default for lagg(4) as it's currently incompatible with 654 the lacp and loadbalance protocols. 655 656 This can be re-enabled by setting the following in loader.conf: 657 net.link.lagg.default_use_flowid="1" 658 65920180102: 660 The SW_WATCHDOG option is no longer necessary to enable the 661 hardclock-based software watchdog if no hardware watchdog is 662 configured. As before, SW_WATCHDOG will cause the software 663 watchdog to be enabled even if a hardware watchdog is configured. 664 66520171215: 666 r326887 fixes the issue described in the 20171214 UPDATING entry. 667 r326888 flips the switch back to building GELI support always. 668 66920171214: 670 r362593 broke ZFS + GELI support for reasons unknown. However, 671 it also broke ZFS support generally, so GELI has been turned off 672 by default as the lesser evil in r326857. If you boot off ZFS and/or 673 GELI, it might not be a good time to update. 674 67520171125: 676 PowerPC users must update loader(8) by rebuilding world before 677 installing a new kernel, as the protocol connecting them has 678 changed. Without the update, loader metadata will not be passed 679 successfully to the kernel and users will have to enter their 680 root partition at the kernel mountroot prompt to continue booting. 681 Newer versions of loader can boot old kernels without issue. 682 68320171110: 684 The LOADER_FIREWIRE_SUPPORT build variable as been renamed to 685 WITH/OUT_LOADER_FIREWIRE. LOADER_{NO_,}GELI_SUPPORT has been renamed 686 to WITH/OUT_LOADER_GELI. 687 68820171106: 689 The naive and non-compliant support of posix_fallocate(2) in ZFS 690 has been removed as of r325320. The system call now returns EINVAL 691 when used on a ZFS file. Although the new behavior complies with the 692 standard, some consumers are not prepared to cope with it. 693 One known victim is lld prior to r325420. 694 69520171102: 696 Building in a FreeBSD src checkout will automatically create object 697 directories now rather than store files in the current directory if 698 'make obj' was not ran. Calling 'make obj' is no longer necessary. 699 This feature can be disabled by setting WITHOUT_AUTO_OBJ=yes in 700 /etc/src-env.conf (not /etc/src.conf), or passing the option in the 701 environment. 702 70320171101: 704 The default MAKEOBJDIR has changed from /usr/obj/<srcdir> for native 705 builds, and /usr/obj/<arch>/<srcdir> for cross-builds, to a unified 706 /usr/obj/<srcdir>/<arch>. This behavior can be changed to the old 707 format by setting WITHOUT_UNIFIED_OBJDIR=yes in /etc/src-env.conf, 708 the environment, or with -DWITHOUT_UNIFIED_OBJDIR when building. 709 The UNIFIED_OBJDIR option is a transitional feature that will be 710 removed for 12.0 release; please migrate to the new format for any 711 tools by looking up the OBJDIR used by 'make -V .OBJDIR' means rather 712 than hardcoding paths. 713 71420171028: 715 The native-xtools target no longer installs the files by default to the 716 OBJDIR. Use the native-xtools-install target with a DESTDIR to install 717 to ${DESTDIR}/${NXTP} where NXTP defaults to /nxb-bin. 718 71920171021: 720 As part of the boot loader infrastructure cleanup, LOADER_*_SUPPORT 721 options are changing from controlling the build if defined / undefined 722 to controlling the build with explicit 'yes' or 'no' values. They will 723 shift to WITH/WITHOUT options to match other options in the system. 724 72520171010: 726 libstand has turned into a private library for sys/boot use only. 727 It is no longer supported as a public interface outside of sys/boot. 728 72920171005: 730 The arm port has split armv6 into armv6 and armv7. armv7 is now 731 a valid TARGET_ARCH/MACHINE_ARCH setting. If you have an armv7 system 732 and are running a kernel from before r324363, you will need to add 733 MACHINE_ARCH=armv7 to 'make buildworld' to do a native build. 734 73520171003: 736 When building multiple kernels using KERNCONF, non-existent KERNCONF 737 files will produce an error and buildkernel will fail. Previously 738 missing KERNCONF files silently failed giving no indication as to 739 why, only to subsequently discover during installkernel that the 740 desired kernel was never built in the first place. 741 74220170912: 743 The default serial number format for CTL LUNs has changed. This will 744 affect users who use /dev/diskid/* device nodes, or whose FibreChannel 745 or iSCSI clients care about their LUNs' serial numbers. Users who 746 require serial number stability should hardcode serial numbers in 747 /etc/ctl.conf . 748 74920170912: 750 For 32-bit arm compiled for hard-float support, soft-floating point 751 binaries now always get their shared libraries from 752 LD_SOFT_LIBRARY_PATH (in the past, this was only used if 753 /usr/libsoft also existed). Only users with a hard-float ld.so, but 754 soft-float everything else should be affected. 755 75620170826: 757 The geli password typed at boot is now hidden. To restore the previous 758 behavior, see geli(8) for configuration options. 759 76020170825: 761 Move PMTUD blackhole counters to TCPSTATS and remove them from bare 762 sysctl values. Minor nit, but requires a rebuild of both world/kernel 763 to complete. 764 76520170814: 766 "make check" behavior (made in ^/head@r295380) has been changed to 767 execute from a limited sandbox, as opposed to executing from 768 ${TESTSDIR}. 769 770 Behavioral changes: 771 - The "beforecheck" and "aftercheck" targets are now specified. 772 - ${CHECKDIR} (added in commit noted above) has been removed. 773 - Legacy behavior can be enabled by setting 774 WITHOUT_MAKE_CHECK_USE_SANDBOX in src.conf(5) or the environment. 775 776 If the limited sandbox mode is enabled, "make check" will execute 777 "make distribution", then install, execute the tests, and clean up the 778 sandbox if successful. 779 780 The "make distribution" and "make install" targets are typically run as 781 root to set appropriate permissions and ownership at installation time. 782 The end-user should set "WITH_INSTALL_AS_USER" in src.conf(5) or the 783 environment if executing "make check" with limited sandbox mode using 784 an unprivileged user. 785 78620170808: 787 Since the switch to GPT disk labels, fsck for UFS/FFS has been 788 unable to automatically find alternate superblocks. As of r322297, 789 the information needed to find alternate superblocks has been 790 moved to the end of the area reserved for the boot block. 791 Filesystems created with a newfs of this vintage or later 792 will create the recovery information. If you have a filesystem 793 created prior to this change and wish to have a recovery block 794 created for your filesystem, you can do so by running fsck in 795 foreground mode (i.e., do not use the -p or -y options). As it 796 starts, fsck will ask ``SAVE DATA TO FIND ALTERNATE SUPERBLOCKS'' 797 to which you should answer yes. 798 79920170728: 800 As of r321665, an NFSv4 server configuration that services 801 Kerberos mounts or clients that do not support the uid/gid in 802 owner/owner_group string capability, must explicitly enable 803 the nfsuserd daemon by adding nfsuserd_enable="YES" to the 804 machine's /etc/rc.conf file. 805 80620170722: 807 Clang, llvm, lldb, compiler-rt and libc++ have been upgraded to 5.0.0. 808 Please see the 20141231 entry below for information about prerequisites 809 and upgrading, if you are not already using clang 3.5.0 or higher. 810 81120170701: 812 WITHOUT_RCMDS is now the default. Set WITH_RCMDS if you need the 813 r-commands (rlogin, rsh, etc.) to be built with the base system. 814 81520170625: 816 The FreeBSD/powerpc platform now uses a 64-bit type for time_t. This is 817 a very major ABI incompatible change, so users of FreeBSD/powerpc must 818 be careful when performing source upgrades. It is best to run 819 'make installworld' from an alternate root system, either a live 820 CD/memory stick, or a temporary root partition. Additionally, all ports 821 must be recompiled. powerpc64 is largely unaffected, except in the case 822 of 32-bit compatibility. All 32-bit binaries will be affected. 823 82420170623: 825 Forward compatibility for the "ino64" project have been committed. This 826 will allow most new binaries to run on older kernels in a limited 827 fashion. This prevents many of the common foot-shooting actions in the 828 upgrade as well as the limited ability to roll back the kernel across 829 the ino64 upgrade. Complicated use cases may not work properly, though 830 enough simpler ones work to allow recovery in most situations. 831 83220170620: 833 Switch back to the BSDL dtc (Device Tree Compiler). Set WITH_GPL_DTC 834 if you require the GPL compiler. 835 83620170618: 837 The internal ABI used for communication between the NFS kernel modules 838 was changed by r320085, so __FreeBSD_version was bumped to 839 ensure all the NFS related modules are updated together. 840 84120170617: 842 The ABI of struct event was changed by extending the data 843 member to 64bit and adding ext fields. For upgrade, same 844 precautions as for the entry 20170523 "ino64" must be 845 followed. 846 84720170531: 848 The GNU roff toolchain has been removed from base. To render manpages 849 which are not supported by mandoc(1), man(1) can fallback on GNU roff 850 from ports (and recommends to install it). 851 To render roff(7) documents, consider using GNU roff from ports or the 852 heirloom doctools roff toolchain from ports via pkg install groff or 853 via pkg install heirloom-doctools. 854 85520170524: 856 The ath(4) and ath_hal(4) modules now build piecemeal to allow for 857 smaller runtime footprint builds. This is useful for embedded systems 858 which only require one chipset support. 859 860 If you load it as a module, make sure this is in /boot/loader.conf: 861 862 if_ath_load="YES" 863 864 This will load the HAL, all chip/RF backends and if_ath_pci. 865 If you have if_ath_pci in /boot/loader.conf, ensure it is after 866 if_ath or it will not load any HAL chipset support. 867 868 If you want to selectively load things (eg on ye cheape ARM/MIPS 869 platforms where RAM is at a premium) you should: 870 871 * load ath_hal 872 * load the chip modules in question 873 * load ath_rate, ath_dfs 874 * load ath_main 875 * load if_ath_pci and/or if_ath_ahb depending upon your particular 876 bus bind type - this is where probe/attach is done. 877 878 For further comments/feedback, poke adrian@ . 879 88020170523: 881 The "ino64" 64-bit inode project has been committed, which extends 882 a number of types to 64 bits. Upgrading in place requires care and 883 adherence to the documented upgrade procedure. 884 885 If using a custom kernel configuration ensure that the 886 COMPAT_FREEBSD11 option is included (as during the upgrade the 887 system will be running the ino64 kernel with the existing world). 888 889 For the safest in-place upgrade begin by removing previous build 890 artifacts via "rm -rf /usr/obj/*". Then, carefully follow the full 891 procedure documented below under the heading "To rebuild everything and 892 install it on the current system." Specifically, a reboot is required 893 after installing the new kernel before installing world. While an 894 installworld normally works by accident from multiuser after rebooting 895 the proper kernel, there are many cases where this will fail across this 896 upgrade and installworld from single user is required. 897 89820170424: 899 The NATM framework including the en(4), fatm(4), hatm(4), and 900 patm(4) devices has been removed. Consumers should plan a 901 migration before the end-of-life date for FreeBSD 11. 902 90320170420: 904 GNU diff has been replaced by a BSD licensed diff. Some features of GNU 905 diff has not been implemented, if those are needed a newer version of 906 GNU diff is available via the diffutils package under the gdiff name. 907 90820170413: 909 As of r316810 for ipfilter, keep frags is no longer assumed when 910 keep state is specified in a rule. r316810 aligns ipfilter with 911 documentation in man pages separating keep frags from keep state. 912 This allows keep state to be specified without forcing keep frags 913 and allows keep frags to be specified independently of keep state. 914 To maintain previous behaviour, also specify keep frags with 915 keep state (as documented in ipf.conf.5). 916 91720170407: 918 arm64 builds now use the base system LLD 4.0.0 linker by default, 919 instead of requiring that the aarch64-binutils port or package be 920 installed. To continue using aarch64-binutils, set 921 CROSS_BINUTILS_PREFIX=/usr/local/aarch64-freebsd/bin . 922 92320170405: 924 The UDP optimization in entry 20160818 that added the sysctl 925 net.inet.udp.require_l2_bcast has been reverted. L2 broadcast 926 packets will no longer be treated as L3 broadcast packets. 927 92820170331: 929 Binds and sends to the loopback addresses, IPv6 and IPv4, will now 930 use any explicitly assigned loopback address available in the jail 931 instead of using the first assigned address of the jail. 932 93320170329: 934 The ctl.ko module no longer implements the iSCSI target frontend: 935 cfiscsi.ko does instead. 936 937 If building cfiscsi.ko as a kernel module, the module can be loaded 938 via one of the following methods: 939 - `cfiscsi_load="YES"` in loader.conf(5). 940 - Add `cfiscsi` to `$kld_list` in rc.conf(5). 941 - ctladm(8)/ctld(8), when compiled with iSCSI support 942 (`WITH_ISCSI=yes` in src.conf(5)) 943 944 Please see cfiscsi(4) for more details. 945 94620170316: 947 The mmcsd.ko module now additionally depends on geom_flashmap.ko. 948 Also, mmc.ko and mmcsd.ko need to be a matching pair built from the 949 same source (previously, the dependency of mmcsd.ko on mmc.ko was 950 missing, but mmcsd.ko now will refuse to load if it is incompatible 951 with mmc.ko). 952 95320170315: 954 The syntax of ipfw(8) named states was changed to avoid ambiguity. 955 If you have used named states in the firewall rules, you need to modify 956 them after installworld and before rebooting. Now named states must 957 be prefixed with colon. 958 95920170311: 960 The old drm (sys/dev/drm/) drivers for i915 and radeon have been 961 removed as the userland we provide cannot use them. The KMS version 962 (sys/dev/drm2) supports the same hardware. 963 96420170302: 965 Clang, llvm, lldb, compiler-rt and libc++ have been upgraded to 4.0.0. 966 Please see the 20141231 entry below for information about prerequisites 967 and upgrading, if you are not already using clang 3.5.0 or higher. 968 96920170221: 970 The code that provides support for ZFS .zfs/ directory functionality 971 has been reimplemented. It's not possible now to create a snapshot 972 by mkdir under .zfs/snapshot/. That should be the only user visible 973 change. 974 97520170216: 976 EISA bus support has been removed. The WITH_EISA option is no longer 977 valid. 978 97920170215: 980 MCA bus support has been removed. 981 98220170127: 983 The WITH_LLD_AS_LD / WITHOUT_LLD_AS_LD build knobs have been renamed 984 WITH_LLD_IS_LD / WITHOUT_LLD_IS_LD, for consistency with CLANG_IS_CC. 985 98620170112: 987 The EM_MULTIQUEUE kernel configuration option is deprecated now that 988 the em(4) driver conforms to iflib specifications. 989 99020170109: 991 The igb(4), em(4) and lem(4) ethernet drivers are now implemented via 992 IFLIB. If you have a custom kernel configuration that excludes em(4) 993 but you use igb(4), you need to re-add em(4) to your custom 994 configuration. 995 99620161217: 997 Clang, llvm, lldb, compiler-rt and libc++ have been upgraded to 3.9.1. 998 Please see the 20141231 entry below for information about prerequisites 999 and upgrading, if you are not already using clang 3.5.0 or higher. 1000 100120161124: 1002 Clang, llvm, lldb, compiler-rt and libc++ have been upgraded to 3.9.0. 1003 Please see the 20141231 entry below for information about prerequisites 1004 and upgrading, if you are not already using clang 3.5.0 or higher. 1005 100620161119: 1007 The layout of the pmap structure has changed for powerpc to put the pmap 1008 statistics at the front for all CPU variations. libkvm(3) and all tools 1009 that link against it need to be recompiled. 1010 101120161030: 1012 isl(4) and cyapa(4) drivers now require a new driver, 1013 chromebook_platform(4), to work properly on Chromebook-class hardware. 1014 On other types of hardware the drivers may need to be configured using 1015 device hints. Please see the corresponding manual pages for details. 1016 101720161017: 1018 The urtwn(4) driver was merged into rtwn(4) and now consists of 1019 rtwn(4) main module + rtwn_usb(4) and rtwn_pci(4) bus-specific 1020 parts. 1021 Also, firmware for RTL8188CE was renamed due to possible name 1022 conflict (rtwnrtl8192cU(B) -> rtwnrtl8192cE(B)) 1023 102420161015: 1025 GNU rcs has been removed from base. It is available as packages: 1026 - rcs: Latest GPLv3 GNU rcs version. 1027 - rcs57: Copy of the latest version of GNU rcs (GPLv2) before it was 1028 removed from base. 1029 103020161008: 1031 Use of the cc_cdg, cc_chd, cc_hd, or cc_vegas congestion control 1032 modules now requires that the kernel configuration contain the 1033 TCP_HHOOK option. (This option is included in the GENERIC kernel.) 1034 103520161003: 1036 The WITHOUT_ELFCOPY_AS_OBJCOPY src.conf(5) knob has been retired. 1037 ELF Tool Chain's elfcopy is always installed as /usr/bin/objcopy. 1038 103920160924: 1040 Relocatable object files with the extension of .So have been renamed 1041 to use an extension of .pico instead. The purpose of this change is 1042 to avoid a name clash with shared libraries on case-insensitive file 1043 systems. On those file systems, foo.So is the same file as foo.so. 1044 104520160918: 1046 GNU rcs has been turned off by default. It can (temporarily) be built 1047 again by adding WITH_RCS knob in src.conf. 1048 Otherwise, GNU rcs is available from packages: 1049 - rcs: Latest GPLv3 GNU rcs version. 1050 - rcs57: Copy of the latest version of GNU rcs (GPLv2) from base. 1051 105220160918: 1053 The backup_uses_rcs functionality has been removed from rc.subr. 1054 105520160908: 1056 The queue(3) debugging macro, QUEUE_MACRO_DEBUG, has been split into 1057 two separate components, QUEUE_MACRO_DEBUG_TRACE and 1058 QUEUE_MACRO_DEBUG_TRASH. Define both for the original 1059 QUEUE_MACRO_DEBUG behavior. 1060 106120160824: 1062 r304787 changed some ioctl interfaces between the iSCSI userspace 1063 programs and the kernel. ctladm, ctld, iscsictl, and iscsid must be 1064 rebuilt to work with new kernels. __FreeBSD_version has been bumped 1065 to 1200005. 1066 106720160818: 1068 The UDP receive code has been updated to only treat incoming UDP 1069 packets that were addressed to an L2 broadcast address as L3 1070 broadcast packets. It is not expected that this will affect any 1071 standards-conforming UDP application. The new behaviour can be 1072 disabled by setting the sysctl net.inet.udp.require_l2_bcast to 1073 0. 1074 107520160818: 1076 Remove the openbsd_poll system call. 1077 __FreeBSD_version has been bumped because of this. 1078 107920160708: 1080 The stable/11 branch has been created from head@r302406. 1081 108220160622: 1083 The libc stub for the pipe(2) system call has been replaced with 1084 a wrapper that calls the pipe2(2) system call and the pipe(2) 1085 system call is now only implemented by the kernels that include 1086 "options COMPAT_FREEBSD10" in their config file (this is the 1087 default). Users should ensure that this option is enabled in 1088 their kernel or upgrade userspace to r302092 before upgrading their 1089 kernel. 1090 109120160527: 1092 CAM will now strip leading spaces from SCSI disks' serial numbers. 1093 This will affect users who create UFS filesystems on SCSI disks using 1094 those disk's diskid device nodes. For example, if /etc/fstab 1095 previously contained a line like 1096 "/dev/diskid/DISK-%20%20%20%20%20%20%20ABCDEFG0123456", you should 1097 change it to "/dev/diskid/DISK-ABCDEFG0123456". Users of geom 1098 transforms like gmirror may also be affected. ZFS users should 1099 generally be fine. 1100 110120160523: 1102 The bitstring(3) API has been updated with new functionality and 1103 improved performance. But it is binary-incompatible with the old API. 1104 Objects built with the new headers may not be linked against objects 1105 built with the old headers. 1106 110720160520: 1108 The brk and sbrk functions have been removed from libc on arm64. 1109 Binutils from ports has been updated to not link to these 1110 functions and should be updated to the latest version before 1111 installing a new libc. 1112 111320160517: 1114 The armv6 port now defaults to hard float ABI. Limited support 1115 for running both hardfloat and soft float on the same system 1116 is available using the libraries installed with -DWITH_LIBSOFT. 1117 This has only been tested as an upgrade path for installworld 1118 and packages may fail or need manual intervention to run. New 1119 packages will be needed. 1120 1121 To update an existing self-hosted armv6hf system, you must add 1122 TARGET_ARCH=armv6 on the make command line for both the build 1123 and the install steps. 1124 112520160510: 1126 Kernel modules compiled outside of a kernel build now default to 1127 installing to /boot/modules instead of /boot/kernel. Many kernel 1128 modules built this way (such as those in ports) already overrode 1129 KMODDIR explicitly to install into /boot/modules. However, 1130 manually building and installing a module from /sys/modules will 1131 now install to /boot/modules instead of /boot/kernel. 1132 113320160414: 1134 The CAM I/O scheduler has been committed to the kernel. There should be 1135 no user visible impact. This does enable NCQ Trim on ada SSDs. While the 1136 list of known rogues that claim support for this but actually corrupt 1137 data is believed to be complete, be on the lookout for data 1138 corruption. The known rogue list is believed to be complete: 1139 1140 o Crucial MX100, M550 drives with MU01 firmware. 1141 o Micron M510 and M550 drives with MU01 firmware. 1142 o Micron M500 prior to MU07 firmware 1143 o Samsung 830, 840, and 850 all firmwares 1144 o FCCT M500 all firmwares 1145 1146 Crucial has firmware http://www.crucial.com/usa/en/support-ssd-firmware 1147 with working NCQ TRIM. For Micron branded drives, see your sales rep for 1148 updated firmware. Black listed drives will work correctly because these 1149 drives work correctly so long as no NCQ TRIMs are sent to them. Given 1150 this list is the same as found in Linux, it's believed there are no 1151 other rogues in the market place. All other models from the above 1152 vendors work. 1153 1154 To be safe, if you are at all concerned, you can quirk each of your 1155 drives to prevent NCQ from being sent by setting: 1156 kern.cam.ada.X.quirks="0x2" 1157 in loader.conf. If the drive requires the 4k sector quirk, set the 1158 quirks entry to 0x3. 1159 116020160330: 1161 The FAST_DEPEND build option has been removed and its functionality is 1162 now the one true way. The old mkdep(1) style of 'make depend' has 1163 been removed. See 20160311 for further details. 1164 116520160317: 1166 Resource range types have grown from unsigned long to uintmax_t. All 1167 drivers, and anything using libdevinfo, need to be recompiled. 1168 116920160311: 1170 WITH_FAST_DEPEND is now enabled by default for in-tree and out-of-tree 1171 builds. It no longer runs mkdep(1) during 'make depend', and the 1172 'make depend' stage can safely be skipped now as it is auto ran 1173 when building 'make all' and will generate all SRCS and DPSRCS before 1174 building anything else. Dependencies are gathered at compile time with 1175 -MF flags kept in separate .depend files per object file. Users should 1176 run 'make cleandepend' once if using -DNO_CLEAN to clean out older 1177 stale .depend files. 1178 117920160306: 1180 On amd64, clang 3.8.0 can now insert sections of type AMD64_UNWIND into 1181 kernel modules. Therefore, if you load any kernel modules at boot time, 1182 please install the boot loaders after you install the kernel, but before 1183 rebooting, e.g.: 1184 1185 make buildworld 1186 make buildkernel KERNCONF=YOUR_KERNEL_HERE 1187 make installkernel KERNCONF=YOUR_KERNEL_HERE 1188 make -C sys/boot install 1189 <reboot in single user> 1190 1191 Then follow the usual steps, described in the General Notes section, 1192 below. 1193 119420160305: 1195 Clang, llvm, lldb and compiler-rt have been upgraded to 3.8.0. Please 1196 see the 20141231 entry below for information about prerequisites and 1197 upgrading, if you are not already using clang 3.5.0 or higher. 1198 119920160301: 1200 The AIO subsystem is now a standard part of the kernel. The 1201 VFS_AIO kernel option and aio.ko kernel module have been removed. 1202 Due to stability concerns, asynchronous I/O requests are only 1203 permitted on sockets and raw disks by default. To enable 1204 asynchronous I/O requests on all file types, set the 1205 vfs.aio.enable_unsafe sysctl to a non-zero value. 1206 120720160226: 1208 The ELF object manipulation tool objcopy is now provided by the 1209 ELF Tool Chain project rather than by GNU binutils. It should be a 1210 drop-in replacement, with the addition of arm64 support. The 1211 (temporary) src.conf knob WITHOUT_ELFCOPY_AS_OBJCOPY knob may be set 1212 to obtain the GNU version if necessary. 1213 121420160129: 1215 Building ZFS pools on top of zvols is prohibited by default. That 1216 feature has never worked safely; it's always been prone to deadlocks. 1217 Using a zvol as the backing store for a VM guest's virtual disk will 1218 still work, even if the guest is using ZFS. Legacy behavior can be 1219 restored by setting vfs.zfs.vol.recursive=1. 1220 122120160119: 1222 The NONE and HPN patches has been removed from OpenSSH. They are 1223 still available in the security/openssh-portable port. 1224 122520160113: 1226 With the addition of ypldap(8), a new _ypldap user is now required 1227 during installworld. "mergemaster -p" can be used to add the user 1228 prior to installworld, as documented in the handbook. 1229 123020151216: 1231 The tftp loader (pxeboot) now uses the option root-path directive. As a 1232 consequence it no longer looks for a pxeboot.4th file on the tftp 1233 server. Instead it uses the regular /boot infrastructure as with the 1234 other loaders. 1235 123620151211: 1237 The code to start recording plug and play data into the modules has 1238 been committed. While the old tools will properly build a new kernel, 1239 a number of warnings about "unknown metadata record 4" will be produced 1240 for an older kldxref. To avoid such warnings, make sure to rebuild 1241 the kernel toolchain (or world). Make sure that you have r292078 or 1242 later when trying to build 292077 or later before rebuilding. 1243 124420151207: 1245 Debug data files are now built by default with 'make buildworld' and 1246 installed with 'make installworld'. This facilitates debugging but 1247 requires more disk space both during the build and for the installed 1248 world. Debug files may be disabled by setting WITHOUT_DEBUG_FILES=yes 1249 in src.conf(5). 1250 125120151130: 1252 r291527 changed the internal interface between the nfsd.ko and 1253 nfscommon.ko modules. As such, they must both be upgraded to-gether. 1254 __FreeBSD_version has been bumped because of this. 1255 125620151108: 1257 Add support for unicode collation strings leads to a change of 1258 order of files listed by ls(1) for example. To get back to the old 1259 behaviour, set LC_COLLATE environment variable to "C". 1260 1261 Databases administrators will need to reindex their databases given 1262 collation results will be different. 1263 1264 Due to a bug in install(1) it is recommended to remove the ancient 1265 locales before running make installworld. 1266 1267 rm -rf /usr/share/locale/* 1268 126920151030: 1270 The OpenSSL has been upgraded to 1.0.2d. Any binaries requiring 1271 libcrypto.so.7 or libssl.so.7 must be recompiled. 1272 127320151020: 1274 Qlogic 24xx/25xx firmware images were updated from 5.5.0 to 7.3.0. 1275 Kernel modules isp_2400_multi and isp_2500_multi were removed and 1276 should be replaced with isp_2400 and isp_2500 modules respectively. 1277 127820151017: 1279 The build previously allowed using 'make -n' to not recurse into 1280 sub-directories while showing what commands would be executed, and 1281 'make -n -n' to recursively show commands. Now 'make -n' will recurse 1282 and 'make -N' will not. 1283 128420151012: 1285 If you specify SENDMAIL_MC or SENDMAIL_CF in make.conf, mergemaster 1286 and etcupdate will now use this file. A custom sendmail.cf is now 1287 updated via this mechanism rather than via installworld. If you had 1288 excluded sendmail.cf in mergemaster.rc or etcupdate.conf, you may 1289 want to remove the exclusion or change it to "always install". 1290 /etc/mail/sendmail.cf is now managed the same way regardless of 1291 whether SENDMAIL_MC/SENDMAIL_CF is used. If you are not using 1292 SENDMAIL_MC/SENDMAIL_CF there should be no change in behavior. 1293 129420151011: 1295 Compatibility shims for legacy ATA device names have been removed. 1296 It includes ATA_STATIC_ID kernel option, kern.cam.ada.legacy_aliases 1297 and kern.geom.raid.legacy_aliases loader tunables, kern.devalias.* 1298 environment variables, /dev/ad* and /dev/ar* symbolic links. 1299 130020151006: 1301 Clang, llvm, lldb, compiler-rt and libc++ have been upgraded to 3.7.0. 1302 Please see the 20141231 entry below for information about prerequisites 1303 and upgrading, if you are not already using clang 3.5.0 or higher. 1304 130520150924: 1306 Kernel debug files have been moved to /usr/lib/debug/boot/kernel/, 1307 and renamed from .symbols to .debug. This reduces the size requirements 1308 on the boot partition or file system and provides consistency with 1309 userland debug files. 1310 1311 When using the supported kernel installation method the 1312 /usr/lib/debug/boot/kernel directory will be renamed (to kernel.old) 1313 as is done with /boot/kernel. 1314 1315 Developers wishing to maintain the historical behavior of installing 1316 debug files in /boot/kernel/ can set KERN_DEBUGDIR="" in src.conf(5). 1317 131820150827: 1319 The wireless drivers had undergone changes that remove the 'parent 1320 interface' from the ifconfig -l output. The rc.d network scripts 1321 used to check presence of a parent interface in the list, so old 1322 scripts would fail to start wireless networking. Thus, etcupdate(3) 1323 or mergemaster(8) run is required after kernel update, to update your 1324 rc.d scripts in /etc. 1325 132620150827: 1327 pf no longer supports 'scrub fragment crop' or 'scrub fragment drop-ovl' 1328 These configurations are now automatically interpreted as 1329 'scrub fragment reassemble'. 1330 133120150817: 1332 Kernel-loadable modules for the random(4) device are back. To use 1333 them, the kernel must have 1334 1335 device random 1336 options RANDOM_LOADABLE 1337 1338 kldload(8) can then be used to load random_fortuna.ko 1339 or random_yarrow.ko. Please note that due to the indirect 1340 function calls that the loadable modules need to provide, 1341 the build-in variants will be slightly more efficient. 1342 1343 The random(4) kernel option RANDOM_DUMMY has been retired due to 1344 unpopularity. It was not all that useful anyway. 1345 134620150813: 1347 The WITHOUT_ELFTOOLCHAIN_TOOLS src.conf(5) knob has been retired. 1348 Control over building the ELF Tool Chain tools is now provided by 1349 the WITHOUT_TOOLCHAIN knob. 1350 135120150810: 1352 The polarity of Pulse Per Second (PPS) capture events with the 1353 uart(4) driver has been corrected. Prior to this change the PPS 1354 "assert" event corresponded to the trailing edge of a positive PPS 1355 pulse and the "clear" event was the leading edge of the next pulse. 1356 1357 As the width of a PPS pulse in a typical GPS receiver is on the 1358 order of 1 millisecond, most users will not notice any significant 1359 difference with this change. 1360 1361 Anyone who has compensated for the historical polarity reversal by 1362 configuring a negative offset equal to the pulse width will need to 1363 remove that workaround. 1364 136520150809: 1366 The default group assigned to /dev/dri entries has been changed 1367 from 'wheel' to 'video' with the id of '44'. If you want to have 1368 access to the dri devices please add yourself to the video group 1369 with: 1370 1371 # pw groupmod video -m $USER 1372 137320150806: 1374 The menu.rc and loader.rc files will now be replaced during 1375 upgrades. Please migrate local changes to menu.rc.local and 1376 loader.rc.local instead. 1377 137820150805: 1379 GNU Binutils versions of addr2line, c++filt, nm, readelf, size, 1380 strings and strip have been removed. The src.conf(5) knob 1381 WITHOUT_ELFTOOLCHAIN_TOOLS no longer provides the binutils tools. 1382 138320150728: 1384 As ZFS requires more kernel stack pages than is the default on some 1385 architectures e.g. i386, it now warns if KSTACK_PAGES is less than 1386 ZFS_MIN_KSTACK_PAGES (which is 4 at the time of writing). 1387 1388 Please consider using 'options KSTACK_PAGES=X' where X is greater 1389 than or equal to ZFS_MIN_KSTACK_PAGES i.e. 4 in such configurations. 1390 139120150706: 1392 sendmail has been updated to 8.15.2. Starting with FreeBSD 11.0 1393 and sendmail 8.15, sendmail uses uncompressed IPv6 addresses by 1394 default, i.e., they will not contain "::". For example, instead 1395 of ::1, it will be 0:0:0:0:0:0:0:1. This permits a zero subnet 1396 to have a more specific match, such as different map entries for 1397 IPv6:0:0 vs IPv6:0. This change requires that configuration 1398 data (including maps, files, classes, custom ruleset, etc.) must 1399 use the same format, so make certain such configuration data is 1400 upgrading. As a very simple check search for patterns like 1401 'IPv6:[0-9a-fA-F:]*::' and 'IPv6::'. To return to the old 1402 behavior, set the m4 option confUSE_COMPRESSED_IPV6_ADDRESSES or 1403 the cf option UseCompressedIPv6Addresses. 1404 140520150630: 1406 The default kernel entropy-processing algorithm is now 1407 Fortuna, replacing Yarrow. 1408 1409 Assuming you have 'device random' in your kernel config 1410 file, the configurations allow a kernel option to override 1411 this default. You may choose *ONE* of: 1412 1413 options RANDOM_YARROW # Legacy /dev/random algorithm. 1414 options RANDOM_DUMMY # Blocking-only driver. 1415 1416 If you have neither, you get Fortuna. For most people, 1417 read no further, Fortuna will give a /dev/random that works 1418 like it always used to, and the difference will be irrelevant. 1419 1420 If you remove 'device random', you get *NO* kernel-processed 1421 entropy at all. This may be acceptable to folks building 1422 embedded systems, but has complications. Carry on reading, 1423 and it is assumed you know what you need. 1424 1425 *PLEASE* read random(4) and random(9) if you are in the 1426 habit of tweaking kernel configs, and/or if you are a member 1427 of the embedded community, wanting specific and not-usual 1428 behaviour from your security subsystems. 1429 1430 NOTE!! If you use RANDOM_DUMMY and/or have no 'device 1431 random', you will NOT have a functioning /dev/random, and 1432 many cryptographic features will not work, including SSH. 1433 You may also find strange behaviour from the random(3) set 1434 of library functions, in particular sranddev(3), srandomdev(3) 1435 and arc4random(3). The reason for this is that the KERN_ARND 1436 sysctl only returns entropy if it thinks it has some to 1437 share, and with RANDOM_DUMMY or no 'device random' this 1438 will never happen. 1439 144020150623: 1441 An additional fix for the issue described in the 20150614 sendmail 1442 entry below has been committed in revision 284717. 1443 144420150616: 1445 FreeBSD's old make (fmake) has been removed from the system. It is 1446 available as the devel/fmake port or via pkg install fmake. 1447 144820150615: 1449 The fix for the issue described in the 20150614 sendmail entry 1450 below has been committed in revision 284436. The work 1451 around described in that entry is no longer needed unless the 1452 default setting is overridden by a confDH_PARAMETERS configuration 1453 setting of '5' or pointing to a 512 bit DH parameter file. 1454 145520150614: 1456 ALLOW_DEPRECATED_ATF_TOOLS/ATFFILE support has been removed from 1457 atf.test.mk (included from bsd.test.mk). Please upgrade devel/atf 1458 and devel/kyua to version 0.20+ and adjust any calling code to work 1459 with Kyuafile and kyua. 1460 146120150614: 1462 The import of openssl to address the FreeBSD-SA-15:10.openssl 1463 security advisory includes a change which rejects handshakes 1464 with DH parameters below 768 bits. sendmail releases prior 1465 to 8.15.2 (not yet released), defaulted to a 512 bit 1466 DH parameter setting for client connections. To work around 1467 this interoperability, sendmail can be configured to use a 1468 2048 bit DH parameter by: 1469 1470 1. Edit /etc/mail/`hostname`.mc 1471 2. If a setting for confDH_PARAMETERS does not exist or 1472 exists and is set to a string beginning with '5', 1473 replace it with '2'. 1474 3. If a setting for confDH_PARAMETERS exists and is set to 1475 a file path, create a new file with: 1476 openssl dhparam -out /path/to/file 2048 1477 4. Rebuild the .cf file: 1478 cd /etc/mail/; make; make install 1479 5. Restart sendmail: 1480 cd /etc/mail/; make restart 1481 1482 A sendmail patch is coming, at which time this file will be 1483 updated. 1484 148520150604: 1486 Generation of legacy formatted entries have been disabled by default 1487 in pwd_mkdb(8), as all base system consumers of the legacy formatted 1488 entries were converted to use the new format by default when the new, 1489 machine independent format have been added and supported since FreeBSD 1490 5.x. 1491 1492 Please see the pwd_mkdb(8) manual page for further details. 1493 149420150525: 1495 Clang and llvm have been upgraded to 3.6.1 release. Please see the 1496 20141231 entry below for information about prerequisites and upgrading, 1497 if you are not already using 3.5.0 or higher. 1498 149920150521: 1500 TI platform code switched to using vendor DTS files and this update 1501 may break existing systems running on Beaglebone, Beaglebone Black, 1502 and Pandaboard: 1503 1504 - dtb files should be regenerated/reinstalled. Filenames are the 1505 same but content is different now 1506 - GPIO addressing was changed, now each GPIO bank (32 pins per bank) 1507 has its own /dev/gpiocX device, e.g. pin 121 on /dev/gpioc0 in old 1508 addressing scheme is now pin 25 on /dev/gpioc3. 1509 - Pandaboard: /etc/ttys should be updated, serial console device is 1510 now /dev/ttyu2, not /dev/ttyu0 1511 151220150501: 1513 soelim(1) from gnu/usr.bin/groff has been replaced by usr.bin/soelim. 1514 If you need the GNU extension from groff soelim(1), install groff 1515 from package: pkg install groff, or via ports: textproc/groff. 1516 151720150423: 1518 chmod, chflags, chown and chgrp now affect symlinks in -R mode as 1519 defined in symlink(7); previously symlinks were silently ignored. 1520 152120150415: 1522 The const qualifier has been removed from iconv(3) to comply with 1523 POSIX. The ports tree is aware of this from r384038 onwards. 1524 152520150416: 1526 Libraries specified by LIBADD in Makefiles must have a corresponding 1527 DPADD_<lib> variable to ensure correct dependencies. This is now 1528 enforced in src.libnames.mk. 1529 153020150324: 1531 From legacy ata(4) driver was removed support for SATA controllers 1532 supported by more functional drivers ahci(4), siis(4) and mvs(4). 1533 Kernel modules ataahci and ataadaptec were removed completely, 1534 replaced by ahci and mvs modules respectively. 1535 153620150315: 1537 Clang, llvm and lldb have been upgraded to 3.6.0 release. Please see 1538 the 20141231 entry below for information about prerequisites and 1539 upgrading, if you are not already using 3.5.0 or higher. 1540 154120150307: 1542 The 32-bit PowerPC kernel has been changed to a position-independent 1543 executable. This can only be booted with a version of loader(8) 1544 newer than January 31, 2015, so make sure to update both world and 1545 kernel before rebooting. 1546 154720150217: 1548 If you are running a -CURRENT kernel since r273872 (Oct 30th, 2014), 1549 but before r278950, the RNG was not seeded properly. Immediately 1550 upgrade the kernel to r278950 or later and regenerate any keys (e.g. 1551 ssh keys or openssl keys) that were generated w/ a kernel from that 1552 range. This does not affect programs that directly used /dev/random 1553 or /dev/urandom. All userland uses of arc4random(3) are affected. 1554 155520150210: 1556 The autofs(4) ABI was changed in order to restore binary compatibility 1557 with 10.1-RELEASE. The automountd(8) daemon needs to be rebuilt to work 1558 with the new kernel. 1559 156020150131: 1561 The powerpc64 kernel has been changed to a position-independent 1562 executable. This can only be booted with a new version of loader(8), 1563 so make sure to update both world and kernel before rebooting. 1564 156520150118: 1566 Clang and llvm have been upgraded to 3.5.1 release. This is a bugfix 1567 only release, no new features have been added. Please see the 20141231 1568 entry below for information about prerequisites and upgrading, if you 1569 are not already using 3.5.0. 1570 157120150107: 1572 ELF tools addr2line, elfcopy (strip), nm, size, and strings are now 1573 taken from the ELF Tool Chain project rather than GNU binutils. They 1574 should be drop-in replacements, with the addition of arm64 support. 1575 The WITHOUT_ELFTOOLCHAIN_TOOLS= knob may be used to obtain the 1576 binutils tools, if necessary. See 20150805 for updated information. 1577 157820150105: 1579 The default Unbound configuration now enables remote control 1580 using a local socket. Users who have already enabled the 1581 local_unbound service should regenerate their configuration 1582 by running "service local_unbound setup" as root. 1583 158420150102: 1585 The GNU texinfo and GNU info pages have been removed. 1586 To be able to view GNU info pages please install texinfo from ports. 1587 158820141231: 1589 Clang, llvm and lldb have been upgraded to 3.5.0 release. 1590 1591 As of this release, a prerequisite for building clang, llvm and lldb is 1592 a C++11 capable compiler and C++11 standard library. This means that to 1593 be able to successfully build the cross-tools stage of buildworld, with 1594 clang as the bootstrap compiler, your system compiler or cross compiler 1595 should either be clang 3.3 or later, or gcc 4.8 or later, and your 1596 system C++ library should be libc++, or libdstdc++ from gcc 4.8 or 1597 later. 1598 1599 On any standard FreeBSD 10.x or 11.x installation, where clang and 1600 libc++ are on by default (that is, on x86 or arm), this should work out 1601 of the box. 1602 1603 On 9.x installations where clang is enabled by default, e.g. on x86 and 1604 powerpc, libc++ will not be enabled by default, so libc++ should be 1605 built (with clang) and installed first. If both clang and libc++ are 1606 missing, build clang first, then use it to build libc++. 1607 1608 On 8.x and earlier installations, upgrade to 9.x first, and then follow 1609 the instructions for 9.x above. 1610 1611 Sparc64 and mips users are unaffected, as they still use gcc 4.2.1 by 1612 default, and do not build clang. 1613 1614 Many embedded systems are resource constrained, and will not be able to 1615 build clang in a reasonable time, or in some cases at all. In those 1616 cases, cross building bootable systems on amd64 is a workaround. 1617 1618 This new version of clang introduces a number of new warnings, of which 1619 the following are most likely to appear: 1620 1621 -Wabsolute-value 1622 1623 This warns in two cases, for both C and C++: 1624 * When the code is trying to take the absolute value of an unsigned 1625 quantity, which is effectively a no-op, and almost never what was 1626 intended. The code should be fixed, if at all possible. If you are 1627 sure that the unsigned quantity can be safely cast to signed, without 1628 loss of information or undefined behavior, you can add an explicit 1629 cast, or disable the warning. 1630 1631 * When the code is trying to take an absolute value, but the called 1632 abs() variant is for the wrong type, which can lead to truncation. 1633 If you want to disable the warning instead of fixing the code, please 1634 make sure that truncation will not occur, or it might lead to unwanted 1635 side-effects. 1636 1637 -Wtautological-undefined-compare and 1638 -Wundefined-bool-conversion 1639 1640 These warn when C++ code is trying to compare 'this' against NULL, while 1641 'this' should never be NULL in well-defined C++ code. However, there is 1642 some legacy (pre C++11) code out there, which actively abuses this 1643 feature, which was less strictly defined in previous C++ versions. 1644 1645 Squid and openjdk do this, for example. The warning can be turned off 1646 for C++98 and earlier, but compiling the code in C++11 mode might result 1647 in unexpected behavior; for example, the parts of the program that are 1648 unreachable could be optimized away. 1649 165020141222: 1651 The old NFS client and server (kernel options NFSCLIENT, NFSSERVER) 1652 kernel sources have been removed. The .h files remain, since some 1653 utilities include them. This will need to be fixed later. 1654 If "mount -t oldnfs ..." is attempted, it will fail. 1655 If the "-o" option on mountd(8), nfsd(8) or nfsstat(1) is used, 1656 the utilities will report errors. 1657 165820141121: 1659 The handling of LOCAL_LIB_DIRS has been altered to skip addition of 1660 directories to top level SUBDIR variable when their parent 1661 directory is included in LOCAL_DIRS. Users with build systems with 1662 such hierarchies and without SUBDIR entries in the parent 1663 directory Makefiles should add them or add the directories to 1664 LOCAL_DIRS. 1665 166620141109: 1667 faith(4) and faithd(8) have been removed from the base system. Faith 1668 has been obsolete for a very long time. 1669 167020141104: 1671 vt(4), the new console driver, is enabled by default. It brings 1672 support for Unicode and double-width characters, as well as 1673 support for UEFI and integration with the KMS kernel video 1674 drivers. 1675 1676 You may need to update your console settings in /etc/rc.conf, 1677 most probably the keymap. During boot, /etc/rc.d/syscons will 1678 indicate what you need to do. 1679 1680 vt(4) still has issues and lacks some features compared to 1681 syscons(4). See the wiki for up-to-date information: 1682 https://wiki.freebsd.org/Newcons 1683 1684 If you want to keep using syscons(4), you can do so by adding 1685 the following line to /boot/loader.conf: 1686 kern.vty=sc 1687 168820141102: 1689 pjdfstest has been integrated into kyua as an opt-in test suite. 1690 Please see share/doc/pjdfstest/README for more details on how to 1691 execute it. 1692 169320141009: 1694 gperf has been removed from the base system for architectures 1695 that use clang. Ports that require gperf will obtain it from the 1696 devel/gperf port. 1697 169820140923: 1699 pjdfstest has been moved from tools/regression/pjdfstest to 1700 contrib/pjdfstest . 1701 170220140922: 1703 At svn r271982, The default linux compat kernel ABI has been adjusted 1704 to 2.6.18 in support of the linux-c6 compat ports infrastructure 1705 update. If you wish to continue using the linux-f10 compat ports, 1706 add compat.linux.osrelease=2.6.16 to your local sysctl.conf. Users are 1707 encouraged to update their linux-compat packages to linux-c6 during 1708 their next update cycle. 1709 171020140729: 1711 The ofwfb driver, used to provide a graphics console on PowerPC when 1712 using vt(4), no longer allows mmap() of all physical memory. This 1713 will prevent Xorg on PowerPC with some ATI graphics cards from 1714 initializing properly unless x11-servers/xorg-server is updated to 1715 1.12.4_8 or newer. 1716 171720140723: 1718 The xdev targets have been converted to using TARGET and 1719 TARGET_ARCH instead of XDEV and XDEV_ARCH. 1720 172120140719: 1722 The default unbound configuration has been modified to address 1723 issues with reverse lookups on networks that use private 1724 address ranges. If you use the local_unbound service, run 1725 "service local_unbound setup" as root to regenerate your 1726 configuration, then "service local_unbound reload" to load the 1727 new configuration. 1728 172920140709: 1730 The GNU texinfo and GNU info pages are not built and installed 1731 anymore, WITH_INFO knob has been added to allow to built and install 1732 them again. 1733 UPDATE: see 20150102 entry on texinfo's removal 1734 173520140708: 1736 The GNU readline library is now an INTERNALLIB - that is, it is 1737 statically linked into consumers (GDB and variants) in the base 1738 system, and the shared library is no longer installed. The 1739 devel/readline port is available for third party software that 1740 requires readline. 1741 174220140702: 1743 The Itanium architecture (ia64) has been removed from the list of 1744 known architectures. This is the first step in the removal of the 1745 architecture. 1746 174720140701: 1748 Commit r268115 has added NFSv4.1 server support, merged from 1749 projects/nfsv4.1-server. Since this includes changes to the 1750 internal interfaces between the NFS related modules, a full 1751 build of the kernel and modules will be necessary. 1752 __FreeBSD_version has been bumped. 1753 175420140629: 1755 The WITHOUT_VT_SUPPORT kernel config knob has been renamed 1756 WITHOUT_VT. (The other _SUPPORT knobs have a consistent meaning 1757 which differs from the behaviour controlled by this knob.) 1758 175920140619: 1760 Maximal length of the serial number in CTL was increased from 16 to 1761 64 chars, that breaks ABI. All CTL-related tools, such as ctladm 1762 and ctld, need to be rebuilt to work with a new kernel. 1763 176420140606: 1765 The libatf-c and libatf-c++ major versions were downgraded to 0 and 1766 1 respectively to match the upstream numbers. They were out of 1767 sync because, when they were originally added to FreeBSD, the 1768 upstream versions were not respected. These libraries are private 1769 and not yet built by default, so renumbering them should be a 1770 non-issue. However, unclean source trees will yield broken test 1771 programs once the operator executes "make delete-old-libs" after a 1772 "make installworld". 1773 1774 Additionally, the atf-sh binary was made private by moving it into 1775 /usr/libexec/. Already-built shell test programs will keep the 1776 path to the old binary so they will break after "make delete-old" 1777 is run. 1778 1779 If you are using WITH_TESTS=yes (not the default), wipe the object 1780 tree and rebuild from scratch to prevent spurious test failures. 1781 This is only needed once: the misnumbered libraries and misplaced 1782 binaries have been added to OptionalObsoleteFiles.inc so they will 1783 be removed during a clean upgrade. 1784 178520140512: 1786 Clang and llvm have been upgraded to 3.4.1 release. 1787 178820140508: 1789 We bogusly installed src.opts.mk in /usr/share/mk. This file should 1790 be removed to avoid issues in the future (and has been added to 1791 ObsoleteFiles.inc). 1792 179320140505: 1794 /etc/src.conf now affects only builds of the FreeBSD src tree. In the 1795 past, it affected all builds that used the bsd.*.mk files. The old 1796 behavior was a bug, but people may have relied upon it. To get this 1797 behavior back, you can .include /etc/src.conf from /etc/make.conf 1798 (which is still global and isn't changed). This also changes the 1799 behavior of incremental builds inside the tree of individual 1800 directories. Set MAKESYSPATH to ".../share/mk" to do that. 1801 Although this has survived make universe and some upgrade scenarios, 1802 other upgrade scenarios may have broken. At least one form of 1803 temporary breakage was fixed with MAKESYSPATH settings for buildworld 1804 as well... In cases where MAKESYSPATH isn't working with this 1805 setting, you'll need to set it to the full path to your tree. 1806 1807 One side effect of all this cleaning up is that bsd.compiler.mk 1808 is no longer implicitly included by bsd.own.mk. If you wish to 1809 use COMPILER_TYPE, you must now explicitly include bsd.compiler.mk 1810 as well. 1811 181220140430: 1813 The lindev device has been removed since /dev/full has been made a 1814 standard device. __FreeBSD_version has been bumped. 1815 181620140424: 1817 The knob WITHOUT_VI was added to the base system, which controls 1818 building ex(1), vi(1), etc. Older releases of FreeBSD required ex(1) 1819 in order to reorder files share/termcap and didn't build ex(1) as a 1820 build tool, so building/installing with WITH_VI is highly advised for 1821 build hosts for older releases. 1822 1823 This issue has been fixed in stable/9 and stable/10 in r277022 and 1824 r276991, respectively. 1825 182620140418: 1827 The YES_HESIOD knob has been removed. It has been obsolete for 1828 a decade. Please move to using WITH_HESIOD instead or your builds 1829 will silently lack HESIOD. 1830 183120140405: 1832 The uart(4) driver has been changed with respect to its handling 1833 of the low-level console. Previously the uart(4) driver prevented 1834 any process from changing the baudrate or the CLOCAL and HUPCL 1835 control flags. By removing the restrictions, operators can make 1836 changes to the serial console port without having to reboot. 1837 However, when getty(8) is started on the serial device that is 1838 associated with the low-level console, a misconfigured terminal 1839 line in /etc/ttys will now have a real impact. 1840 Before upgrading the kernel, make sure that /etc/ttys has the 1841 serial console device configured as 3wire without baudrate to 1842 preserve the previous behaviour. E.g: 1843 ttyu0 "/usr/libexec/getty 3wire" vt100 on secure 1844 184520140306: 1846 Support for libwrap (TCP wrappers) in rpcbind was disabled by default 1847 to improve performance. To re-enable it, if needed, run rpcbind 1848 with command line option -W. 1849 185020140226: 1851 Switched back to the GPL dtc compiler due to updates in the upstream 1852 dts files not being supported by the BSDL dtc compiler. You will need 1853 to rebuild your kernel toolchain to pick up the new compiler. Core dumps 1854 may result while building dtb files during a kernel build if you fail 1855 to do so. Set WITHOUT_GPL_DTC if you require the BSDL compiler. 1856 185720140216: 1858 Clang and llvm have been upgraded to 3.4 release. 1859 186020140216: 1861 The nve(4) driver has been removed. Please use the nfe(4) driver 1862 for NVIDIA nForce MCP Ethernet adapters instead. 1863 186420140212: 1865 An ABI incompatibility crept into the libc++ 3.4 import in r261283. 1866 This could cause certain C++ applications using shared libraries built 1867 against the previous version of libc++ to crash. The incompatibility 1868 has now been fixed, but any C++ applications or shared libraries built 1869 between r261283 and r261801 should be recompiled. 1870 187120140204: 1872 OpenSSH will now ignore errors caused by kernel lacking of Capsicum 1873 capability mode support. Please note that enabling the feature in 1874 kernel is still highly recommended. 1875 187620140131: 1877 OpenSSH is now built with sandbox support, and will use sandbox as 1878 the default privilege separation method. This requires Capsicum 1879 capability mode support in kernel. 1880 188120140128: 1882 The libelf and libdwarf libraries have been updated to newer 1883 versions from upstream. Shared library version numbers for 1884 these two libraries were bumped. Any ports or binaries 1885 requiring these two libraries should be recompiled. 1886 __FreeBSD_version is bumped to 1100006. 1887 188820140110: 1889 If a Makefile in a tests/ directory was auto-generating a Kyuafile 1890 instead of providing an explicit one, this would prevent such 1891 Makefile from providing its own Kyuafile in the future during 1892 NO_CLEAN builds. This has been fixed in the Makefiles but manual 1893 intervention is needed to clean an objdir if you use NO_CLEAN: 1894 # find /usr/obj -name Kyuafile | xargs rm -f 1895 189620131213: 1897 The behavior of gss_pseudo_random() for the krb5 mechanism 1898 has changed, for applications requesting a longer random string 1899 than produced by the underlying enctype's pseudo-random() function. 1900 In particular, the random string produced from a session key of 1901 enctype aes256-cts-hmac-sha1-96 or aes256-cts-hmac-sha1-96 will 1902 be different at the 17th octet and later, after this change. 1903 The counter used in the PRF+ construction is now encoded as a 1904 big-endian integer in accordance with RFC 4402. 1905 __FreeBSD_version is bumped to 1100004. 1906 190720131108: 1908 The WITHOUT_ATF build knob has been removed and its functionality 1909 has been subsumed into the more generic WITHOUT_TESTS. If you were 1910 using the former to disable the build of the ATF libraries, you 1911 should change your settings to use the latter. 1912 191320131025: 1914 The default version of mtree is nmtree which is obtained from 1915 NetBSD. The output is generally the same, but may vary 1916 slightly. If you found you need identical output adding 1917 "-F freebsd9" to the command line should do the trick. For the 1918 time being, the old mtree is available as fmtree. 1919 192020131014: 1921 libbsdyml has been renamed to libyaml and moved to /usr/lib/private. 1922 This will break ports-mgmt/pkg. Rebuild the port, or upgrade to pkg 1923 1.1.4_8 and verify bsdyml not linked in, before running "make 1924 delete-old-libs": 1925 # make -C /usr/ports/ports-mgmt/pkg build deinstall install clean 1926 or 1927 # pkg install pkg; ldd /usr/local/sbin/pkg | grep bsdyml 1928 192920131010: 1930 The stable/10 branch has been created in subversion from head 1931 revision r256279. 1932 1933COMMON ITEMS: 1934 1935 General Notes 1936 ------------- 1937 Avoid using make -j when upgrading. While generally safe, there are 1938 sometimes problems using -j to upgrade. If your upgrade fails with 1939 -j, please try again without -j. From time to time in the past there 1940 have been problems using -j with buildworld and/or installworld. This 1941 is especially true when upgrading between "distant" versions (eg one 1942 that cross a major release boundary or several minor releases, or when 1943 several months have passed on the -current branch). 1944 1945 Sometimes, obscure build problems are the result of environment 1946 poisoning. This can happen because the make utility reads its 1947 environment when searching for values for global variables. To run 1948 your build attempts in an "environmental clean room", prefix all make 1949 commands with 'env -i '. See the env(1) manual page for more details. 1950 1951 When upgrading from one major version to another it is generally best to 1952 upgrade to the latest code in the currently installed branch first, then 1953 do an upgrade to the new branch. This is the best-tested upgrade path, 1954 and has the highest probability of being successful. Please try this 1955 approach if you encounter problems with a major version upgrade. Since 1956 the stable 4.x branch point, one has generally been able to upgrade from 1957 anywhere in the most recent stable branch to head / current (or even the 1958 last couple of stable branches). See the top of this file when there's 1959 an exception. 1960 1961 When upgrading a live system, having a root shell around before 1962 installing anything can help undo problems. Not having a root shell 1963 around can lead to problems if pam has changed too much from your 1964 starting point to allow continued authentication after the upgrade. 1965 1966 This file should be read as a log of events. When a later event changes 1967 information of a prior event, the prior event should not be deleted. 1968 Instead, a pointer to the entry with the new information should be 1969 placed in the old entry. Readers of this file should also sanity check 1970 older entries before relying on them blindly. Authors of new entries 1971 should write them with this in mind. 1972 1973 ZFS notes 1974 --------- 1975 When upgrading the boot ZFS pool to a new version, always follow 1976 these two steps: 1977 1978 1.) recompile and reinstall the ZFS boot loader and boot block 1979 (this is part of "make buildworld" and "make installworld") 1980 1981 2.) update the ZFS boot block on your boot drive 1982 1983 The following example updates the ZFS boot block on the first 1984 partition (freebsd-boot) of a GPT partitioned drive ada0: 1985 "gpart bootcode -p /boot/gptzfsboot -i 1 ada0" 1986 1987 Non-boot pools do not need these updates. 1988 1989 To build a kernel 1990 ----------------- 1991 If you are updating from a prior version of FreeBSD (even one just 1992 a few days old), you should follow this procedure. It is the most 1993 failsafe as it uses a /usr/obj tree with a fresh mini-buildworld, 1994 1995 make kernel-toolchain 1996 make -DALWAYS_CHECK_MAKE buildkernel KERNCONF=YOUR_KERNEL_HERE 1997 make -DALWAYS_CHECK_MAKE installkernel KERNCONF=YOUR_KERNEL_HERE 1998 1999 To test a kernel once 2000 --------------------- 2001 If you just want to boot a kernel once (because you are not sure 2002 if it works, or if you want to boot a known bad kernel to provide 2003 debugging information) run 2004 make installkernel KERNCONF=YOUR_KERNEL_HERE KODIR=/boot/testkernel 2005 nextboot -k testkernel 2006 2007 To rebuild everything and install it on the current system. 2008 ----------------------------------------------------------- 2009 # Note: sometimes if you are running current you gotta do more than 2010 # is listed here if you are upgrading from a really old current. 2011 2012 <make sure you have good level 0 dumps> 2013 make buildworld 2014 make buildkernel KERNCONF=YOUR_KERNEL_HERE 2015 make installkernel KERNCONF=YOUR_KERNEL_HERE 2016 [1] 2017 <reboot in single user> [3] 2018 mergemaster -Fp [5] 2019 make installworld 2020 mergemaster -Fi [4] 2021 make delete-old [6] 2022 <reboot> 2023 2024 To cross-install current onto a separate partition 2025 -------------------------------------------------- 2026 # In this approach we use a separate partition to hold 2027 # current's root, 'usr', and 'var' directories. A partition 2028 # holding "/", "/usr" and "/var" should be about 2GB in 2029 # size. 2030 2031 <make sure you have good level 0 dumps> 2032 <boot into -stable> 2033 make buildworld 2034 make buildkernel KERNCONF=YOUR_KERNEL_HERE 2035 <maybe newfs current's root partition> 2036 <mount current's root partition on directory ${CURRENT_ROOT}> 2037 make installworld DESTDIR=${CURRENT_ROOT} -DDB_FROM_SRC 2038 make distribution DESTDIR=${CURRENT_ROOT} # if newfs'd 2039 make installkernel KERNCONF=YOUR_KERNEL_HERE DESTDIR=${CURRENT_ROOT} 2040 cp /etc/fstab ${CURRENT_ROOT}/etc/fstab # if newfs'd 2041 <edit ${CURRENT_ROOT}/etc/fstab to mount "/" from the correct partition> 2042 <reboot into current> 2043 <do a "native" rebuild/install as described in the previous section> 2044 <maybe install compatibility libraries from ports/misc/compat*> 2045 <reboot> 2046 2047 2048 To upgrade in-place from stable to current 2049 ---------------------------------------------- 2050 <make sure you have good level 0 dumps> 2051 make buildworld [9] 2052 make buildkernel KERNCONF=YOUR_KERNEL_HERE [8] 2053 make installkernel KERNCONF=YOUR_KERNEL_HERE 2054 [1] 2055 <reboot in single user> [3] 2056 mergemaster -Fp [5] 2057 make installworld 2058 mergemaster -Fi [4] 2059 make delete-old [6] 2060 <reboot> 2061 2062 Make sure that you've read the UPDATING file to understand the 2063 tweaks to various things you need. At this point in the life 2064 cycle of current, things change often and you are on your own 2065 to cope. The defaults can also change, so please read ALL of 2066 the UPDATING entries. 2067 2068 Also, if you are tracking -current, you must be subscribed to 2069 freebsd-current@freebsd.org. Make sure that before you update 2070 your sources that you have read and understood all the recent 2071 messages there. If in doubt, please track -stable which has 2072 much fewer pitfalls. 2073 2074 [1] If you have third party modules, such as vmware, you 2075 should disable them at this point so they don't crash your 2076 system on reboot. 2077 2078 [3] From the bootblocks, boot -s, and then do 2079 fsck -p 2080 mount -u / 2081 mount -a 2082 sh /etc/rc.d/zfs start # mount zfs filesystem, if needed 2083 cd src # full path to source 2084 adjkerntz -i # if CMOS is wall time 2085 Also, when doing a major release upgrade, it is required that 2086 you boot into single user mode to do the installworld. 2087 2088 [4] Note: This step is non-optional. Failure to do this step 2089 can result in a significant reduction in the functionality of the 2090 system. Attempting to do it by hand is not recommended and those 2091 that pursue this avenue should read this file carefully, as well 2092 as the archives of freebsd-current and freebsd-hackers mailing lists 2093 for potential gotchas. The -U option is also useful to consider. 2094 See mergemaster(8) for more information. 2095 2096 [5] Usually this step is a no-op. However, from time to time 2097 you may need to do this if you get unknown user in the following 2098 step. It never hurts to do it all the time. You may need to 2099 install a new mergemaster (cd src/usr.sbin/mergemaster && make 2100 install) after the buildworld before this step if you last updated 2101 from current before 20130425 or from -stable before 20130430. 2102 2103 [6] This only deletes old files and directories. Old libraries 2104 can be deleted by "make delete-old-libs", but you have to make 2105 sure that no program is using those libraries anymore. 2106 2107 [8] The new kernel must be able to run existing binaries used by an 2108 installworld. When upgrading across major versions, the new kernel's 2109 configuration must include the correct COMPAT_FREEBSD<n> option for 2110 existing binaries (e.g. COMPAT_FREEBSD11 to run 11.x binaries). Failure 2111 to do so may leave you with a system that is hard to boot to recover. A 2112 GENERIC kernel will include suitable compatibility options to run 2113 binaries from older branches. Note that the ability to run binaries 2114 from unsupported branches is not guaranteed. 2115 2116 Make sure that you merge any new devices from GENERIC since the 2117 last time you updated your kernel config file. Options also 2118 change over time, so you may need to adjust your custom kernels 2119 for these as well. 2120 2121 [9] If CPUTYPE is defined in your /etc/make.conf, make sure to use the 2122 "?=" instead of the "=" assignment operator, so that buildworld can 2123 override the CPUTYPE if it needs to. 2124 2125 MAKEOBJDIRPREFIX must be defined in an environment variable, and 2126 not on the command line, or in /etc/make.conf. buildworld will 2127 warn if it is improperly defined. 2128FORMAT: 2129 2130This file contains a list, in reverse chronological order, of major 2131breakages in tracking -current. It is not guaranteed to be a complete 2132list of such breakages, and only contains entries since September 23, 2011. 2133If you need to see UPDATING entries from before that date, you will need 2134to fetch an UPDATING file from an older FreeBSD release. 2135 2136Copyright information: 2137 2138Copyright 1998-2009 M.
