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 2920190713: 30 Default permissions on the /var/account/acct file (and copies of it rotated 31 by periodic daily scripts) are changed from 0644 to 0640 because the file 32 contains sensitive information that should not be world-readable. If the 33 /var/account directory must be created by rc.d/accounting, the mode used is 34 now 0750. Admins who use the accounting feature are encouraged to change 35 the mode of an existing /var/account directory to 0750 or 0700. 36 3720190620: 38 Entropy collection and the /dev/random device are no longer optional 39 components. The "device random" option has been removed. 40 Implementations of distilling algorithms can still be made loadable 41 with "options RANDOM_LOADABLE" (e.g., random_fortuna.ko). 42 4320190612: 44 Clang, llvm, lld, lldb, compiler-rt, libc++, libunwind and openmp have 45 been upgraded to 8.0.1. Please see the 20141231 entry below for 46 information about prerequisites and upgrading, if you are not already 47 using clang 3.5.0 or higher. 48 4920190608: 50 A fix was applied to i386 kernel modules to avoid panics with 51 dpcpu or vnet. Users need to recompile i386 kernel modules 52 having pcpu or vnet sections or they will refuse to load. 53 5420190513: 55 User-wired pages now have their own counter, 56 vm.stats.vm.v_user_wire_count. The vm.max_wired sysctl was renamed 57 to vm.max_user_wired and changed from an unsigned int to an unsigned 58 long. bhyve VMs wired with the -S are now subject to the user 59 wiring limit; the vm.max_user_wired sysctl may need to be tuned to 60 avoid running into the limit. 61 6220190507: 63 The IPSEC option has been removed from GENERIC. Users requiring 64 ipsec(4) must now load the ipsec(4) kernel module. 65 6620190507: 67 The tap(4) driver has been folded into tun(4), and the module has been 68 renamed to tuntap. You should update any kld_load="if_tap" or 69 kld_load="if_tun" entries in /etc/rc.conf, if_tap_load="YES" or 70 if_tun_load="YES" entries in /boot/loader.conf to load the if_tuntap 71 module instead, and "device tap" or "device tun" entries in kernel 72 config files to select the tuntap device instead. 73 7420190418: 75 The following knobs have been added related to tradeoffs between 76 safe use of the random device and availability in the absence of 77 entropy: 78 79 kern.random.initial_seeding.bypass_before_seeding: tunable; set 80 non-zero to bypass the random device prior to seeding, or zero to 81 block random requests until the random device is initially seeded. 82 For now, set to 1 (unsafe) by default to restore pre-r346250 boot 83 availability properties. 84 85 kern.random.initial_seeding.read_random_bypassed_before_seeding: 86 read-only diagnostic sysctl that is set when bypass is enabled and 87 read_random(9) is bypassed, to enable programmatic handling of this 88 initial condition, if desired. 89 90 kern.random.initial_seeding.arc4random_bypassed_before_seeding: 91 Similar to the above, but for for arc4random(9) initial seeding. 92 93 kern.random.initial_seeding.disable_bypass_warnings: tunable; set 94 non-zero to disable warnings in dmesg when the same conditions are 95 met as for the diagnostic sysctls above. Defaults to zero, i.e., 96 produce warnings in dmesg when the conditions are met. 97 9820190416: 99 The loadable random module KPI has changed; the random_infra_init() 100 routine now requires a 3rd function pointer for a bool (*)(void) 101 method that returns true if the random device is seeded (and 102 therefore unblocked). 103 10420190404: 105 r345895 reverts r320698. This implies that an nfsuserd(8) daemon 106 built from head sources between r320757 (July 6, 2017) and 107 r338192 (Aug. 22, 2018) will not work unless the "-use-udpsock" 108 is added to the command line. 109 nfsuserd daemons built from head sources that are post-r338192 are 110 not affected and should continue to work. 111 11220190320: 113 The fuse(4) module has been renamed to fusefs(4) for consistency with 114 other filesystems. You should update any kld_load="fuse" entries in 115 /etc/rc.conf, fuse_load="YES" entries in /boot/loader.conf, and 116 "options FUSE" entries in kernel config files. 117 11820190304: 119 Clang, llvm, lld, lldb, compiler-rt and libc++ have been upgraded to 120 8.0.0. Please see the 20141231 entry below for information about 121 prerequisites and upgrading, if you are not already using clang 3.5.0 122 or higher. 123 12420190226: 125 geom_uzip(4) depends on the new module xz. If geom_uzip is statically 126 compiled into your custom kernel, add 'device xz' statement to the 127 kernel config. 128 12920190219: 130 drm and drm2 have been removed from the tree. Please see 131 https://wiki.freebsd.org/Graphics for the latest information on 132 migrating to the drm ports. 133 13420190131: 135 Iflib is no longer unconditionally compiled into the kernel. Drivers 136 using iflib and statically compiled into the kernel, now require 137 the 'device iflib' config option. For the same drivers loaded as 138 modules on kernels not having 'device iflib', the iflib.ko module 139 is loaded automatically. 140 14120190125: 142 The IEEE80211_AMPDU_AGE and AH_SUPPORT_AR5416 kernel configuration 143 options no longer exist since r343219 and r343427 respectively; 144 nothing uses them, so they should be just removed from custom 145 kernel config files. 146 14720181230: 148 r342635 changes the way efibootmgr(8) works by requiring users to add 149 the -b (bootnum) parameter for commands where the bootnum was previously 150 specified with each option. For example 'efibootmgr -B 0001' is now 151 'efibootmgr -B -b 0001'. 152 15320181220: 154 r342286 modifies the NFSv4 server so that it obeys vfs.nfsd.nfs_privport 155 in the same as it is applied to NFSv2 and 3. This implies that NFSv4 156 servers that have vfs.nfsd.nfs_privport set will only allow mounts 157 from clients using a reserved port#. Since both the FreeBSD and Linux 158 NFSv4 clients use reserved port#s by default, this should not affect 159 most NFSv4 mounts. 160 16120181219: 162 The XLP config has been removed. We can't support 64-bit atomics in this 163 kernel because it is running in 32-bit mode. XLP users must transition 164 to running a 64-bit kernel (XLP64 or XLPN32). 165 166 The mips GXEMUL support has been removed from FreeBSD. MALTA* + qemu is 167 the preferred emulator today and we don't need two different ones. 168 169 The old sibyte / swarm / Broadcom BCM1250 support has been 170 removed from the mips port. 171 17220181211: 173 Clang, llvm, lld, lldb, compiler-rt and libc++ have been upgraded to 174 7.0.1. Please see the 20141231 entry below for information about 175 prerequisites and upgrading, if you are not already using clang 3.5.0 176 or higher. 177 17820181211: 179 Remove the timed and netdate programs from the base tree. Setting 180 the time with these daemons has been obsolete for over a decade. 181 18220181126: 183 On amd64, arm64 and armv7 (architectures that install LLVM's ld.lld 184 linker as /usr/bin/ld) GNU ld is no longer installed as ld.bfd, as 185 it produces broken binaries when ifuncs are in use. Users needing 186 GNU ld should install the binutils port or package. 187 18820181123: 189 The BSD crtbegin and crtend code has been enabled by default. It has 190 had extensive testing on amd64, arm64, and i386. It can be disabled 191 by building a world with -DWITHOUT_BSD_CRTBEGIN. 192 19320181115: 194 The set of CTM commands (ctm, ctm_smail, ctm_rmail, ctm_dequeue) 195 has been converted to a port (misc/ctm) and will be removed from 196 FreeBSD-13. It is available as a package (ctm) for all supported 197 FreeBSD versions. 198 19920181110: 200 The default newsyslog.conf(5) file has been changed to only include 201 files in /etc/newsyslog.conf.d/ and /usr/local/etc/newsyslog.conf.d/ if 202 the filenames end in '.conf' and do not begin with a '.'. 203 204 You should check the configuration files in these two directories match 205 this naming convention. You can verify which configuration files are 206 being included using the command: 207 $ newsyslog -Nrv 208 20920181015: 210 Ports for the DRM modules have been simplified. Now, amd64 users should 211 just install the drm-kmod port. All others should install 212 drm-legacy-kmod. 213 214 Graphics hardware that's newer than about 2010 usually works with 215 drm-kmod. For hardware older than 2013, however, some users will need 216 to use drm-legacy-kmod if drm-kmod doesn't work for them. Hardware older 217 than 2008 usually only works in drm-legacy-kmod. The graphics team can 218 only commit to hardware made since 2013 due to the complexity of the 219 market and difficulty to test all the older cards effectively. If you 220 have hardware supported by drm-kmod, you are strongly encouraged to use 221 that as you will get better support. 222 223 Other than KPI chasing, drm-legacy-kmod will not be updated. As outlined 224 elsewhere, the drm and drm2 modules will be eliminated from the src base 225 soon (with a limited exception for arm). Please update to the package 226 asap and report any issues to x11@freebsd.org. 227 228 Generally, anybody using the drm*-kmod packages should add 229 WITHOUT_DRM_MODULE=t and WITHOUT_DRM2_MODULE=t to avoid nasty 230 cross-threading surprises, especially with automatic driver 231 loading from X11 startup. These will become the defaults in 13-current 232 shortly. 233 23420181012: 235 The ixlv(4) driver has been renamed to iavf(4). As a consequence, 236 custom kernel and module loading configuration files must be updated 237 accordingly. Moreover, interfaces previous presented as ixlvN to the 238 system are now exposed as iavfN and network configuration files must 239 be adjusted as necessary. 240 24120181009: 242 OpenSSL has been updated to version 1.1.1. This update included 243 additional various API changes throughout the base system. It is 244 important to rebuild third-party software after upgrading. The value 245 of __FreeBSD_version has been bumped accordingly. 246 24720181006: 248 The legacy DRM modules and drivers have now been added to the loader's 249 module blacklist, in favor of loading them with kld_list in rc.conf(5). 250 The module blacklist may be overridden with the loader.conf(5) 251 'module_blacklist' variable, but loading them via rc.conf(5) is strongly 252 encouraged. 253 25420181002: 255 The cam(4) based nda(4) driver will be used over nvd(4) by default on 256 powerpc64. You may set 'options NVME_USE_NVD=1' in your kernel conf or 257 loader tunable 'hw.nvme.use_nvd=1' if you wish to use the existing 258 driver. Make sure to edit /boot/etc/kboot.conf and fstab to use the 259 nda device name. 260 26120180913: 262 Reproducible build mode is now on by default, in preparation for 263 FreeBSD 12.0. This eliminates build metadata such as the user, 264 host, and time from the kernel (and uname), unless the working tree 265 corresponds to a modified checkout from a version control system. 266 The previous behavior can be obtained by setting the /etc/src.conf 267 knob WITHOUT_REPRODUCIBLE_BUILD. 268 26920180826: 270 The Yarrow CSPRNG has been removed from the kernel as it has not been 271 supported by its designers since at least 2003. Fortuna has been the 272 default since FreeBSD-11. 273 27420180822: 275 devctl freeze/thaw have gone into the tree, the rc scripts have been 276 updated to use them and devmatch has been changed. You should update 277 kernel, userland and rc scripts all at the same time. 278 27920180818: 280 The default interpreter has been switched from 4th to Lua. 281 LOADER_DEFAULT_INTERP, documented in build(7), will override the default 282 interpreter. If you have custom FORTH code you will need to set 283 LOADER_DEFAULT_INTERP=4th (valid values are 4th, lua or simp) in 284 src.conf for the build. This will create default hard links between 285 loader and loader_4th instead of loader and loader_lua, the new default. 286 If you are using UEFI it will create the proper hard link to loader.efi. 287 288 bhyve uses userboot.so. It remains 4th-only until some issues are solved 289 regarding coexisting with multiple versions of FreeBSD are resolved. 290 29120180815: 292 ls(1) now respects the COLORTERM environment variable used in other 293 systems and software to indicate that a colored terminal is both 294 supported and desired. If ls(1) is suddenly emitting colors, they may 295 be disabled again by either removing the unwanted COLORTERM from your 296 environment, or using `ls --color=never`. The ls(1) specific CLICOLOR 297 may not be observed in a future release. 298 29920180808: 300 The default pager for most commands has been changed to "less". To 301 restore the old behavior, set PAGER="more" and MANPAGER="more -s" in 302 your environment. 303 30420180731: 305 The jedec_ts(4) driver has been removed. A superset of its functionality 306 is available in the jedec_dimm(4) driver, and the manpage for that 307 driver includes migration instructions. If you have "device jedec_ts" 308 in your kernel configuration file, it must be removed. 309 31020180730: 311 amd64/GENERIC now has EFI runtime services, EFIRT, enabled by default. 312 This should have no effect if the kernel is booted via BIOS/legacy boot. 313 EFIRT may be disabled via a loader tunable, efi.rt.disabled, if a system 314 has a buggy firmware that prevents a successful boot due to use of 315 runtime services. 316 31720180727: 318 Atmel AT91RM9200 and AT91SAM9, Cavium CNS 11xx and XScale 319 support has been removed from the tree. These ports were 320 obsolete and/or known to be broken for many years. 321 32220180723: 323 loader.efi has been augmented to participate more fully in the 324 UEFI boot manager protocol. loader.efi will now look at the 325 BootXXXX environment variable to determine if a specific kernel 326 or root partition was specified. XXXX is derived from BootCurrent. 327 efibootmgr(8) manages these standard UEFI variables. 328 32920180720: 330 zfsloader's functionality has now been folded into loader. 331 zfsloader is no longer necessary once you've updated your 332 boot blocks. For a transition period, we will install a 333 hardlink for zfsloader to loader to allow a smooth transition 334 until the boot blocks can be updated (hard link because old 335 zfs boot blocks don't understand symlinks). 336 33720180719: 338 ARM64 now have efifb support, if you want to have serial console 339 on your arm64 board when an screen is connected and the bootloader 340 setup a frame buffer for us to use, just add : 341 boot_serial=YES 342 boot_multicons=YES 343 in /boot/loader.conf 344 For Raspberry Pi 3 (RPI) users, this is needed even if you don't have 345 an screen connected as the firmware will setup a frame buffer are that 346 u-boot will expose as an EFI frame buffer. 347 34820180719: 349 New uid:gid added, ntpd:ntpd (123:123). Be sure to run mergemaster 350 or take steps to update /etc/passwd before doing installworld on 351 existing systems. Do not skip the "mergemaster -Fp" step before 352 installworld, as described in the update procedures near the bottom 353 of this document. Also, rc.d/ntpd now starts ntpd(8) as user ntpd 354 if the new mac_ntpd(4) policy is available, unless ntpd_flags or 355 the ntp config file contain options that change file/dir locations. 356 When such options (e.g., "statsdir" or "crypto") are used, ntpd can 357 still be run as non-root by setting ntpd_user=ntpd in rc.conf, after 358 taking steps to ensure that all required files/dirs are accessible 359 by the ntpd user. 360 36120180717: 362 Big endian arm support has been removed. 363 36420180711: 365 The static environment setup in kernel configs is no longer mutually 366 exclusive with the loader(8) environment by default. In order to 367 restore the previous default behavior of disabling the loader(8) 368 environment if a static environment is present, you must specify 369 loader_env.disabled=1 in the static environment. 370 37120180705: 372 The ABI of syscalls used by management tools like sockstat and 373 netstat has been broken to allow 32-bit binaries to work on 374 64-bit kernels without modification. These programs will need 375 to match the kernel in order to function. External programs may 376 require minor modifications to accommodate a change of type in 377 structures from pointers to 64-bit virtual addresses. 378 37920180702: 380 On i386 and amd64 atomics are now inlined. Out of tree modules using 381 atomics will need to be rebuilt. 382 38320180701: 384 The '%I' format in the kern.corefile sysctl limits the number of 385 core files that a process can generate to the number stored in the 386 debug.ncores sysctl. The '%I' format is replaced by the single digit 387 index. Previously, if all indexes were taken the kernel would overwrite 388 only a core file with the highest index in a filename. 389 Currently the system will create a new core file if there is a free 390 index or if all slots are taken it will overwrite the oldest one. 391 39220180630: 393 Clang, llvm, lld, lldb, compiler-rt and libc++ have been upgraded to 394 6.0.1. Please see the 20141231 entry below for information about 395 prerequisites and upgrading, if you are not already using clang 3.5.0 396 or higher. 397 39820180628: 399 r335753 introduced a new quoting method. However, etc/devd/devmatch.conf 400 needed to be changed to work with it. This change was made with r335763 401 and requires a mergemaster / etcupdate / etc to update the installed 402 file. 403 40420180612: 405 r334930 changed the interface between the NFS modules, so they all 406 need to be rebuilt. r335018 did a __FreeBSD_version bump for this. 407 40820180530: 409 As of r334391 lld is the default amd64 system linker; it is installed 410 as /usr/bin/ld. Kernel build workarounds (see 20180510 entry) are no 411 longer necessary. 412 41320180530: 414 The kernel / userland interface for devinfo changed, so you'll 415 need a new kernel and userland as a pair for it to work (rebuilding 416 lib/libdevinfo is all that's required). devinfo and devmatch will 417 not work, but everything else will when there's a mismatch. 418 41920180523: 420 The on-disk format for hwpmc callchain records has changed to include 421 threadid corresponding to a given record. This changes the field offsets 422 and thus requires that libpmcstat be rebuilt before using a kernel 423 later than r334108. 424 42520180517: 426 The vxge(4) driver has been removed. This driver was introduced into 427 HEAD one week before the Exar left the Ethernet market and is not 428 known to be used. If you have device vxge in your kernel config file 429 it must be removed. 430 43120180510: 432 The amd64 kernel now requires a ld that supports ifunc to produce a 433 working kernel, either lld or a newer binutils. lld is built by default 434 on amd64, and the 'buildkernel' target uses it automatically. However, 435 it is not the default linker, so building the kernel the traditional 436 way requires LD=ld.lld on the command line (or LD=/usr/local/bin/ld for 437 binutils port/package). lld will soon be default, and this requirement 438 will go away. 439 440 NOTE: As of r334391 lld is the default system linker on amd64, and no 441 workaround is necessary. 442 44320180508: 444 The nxge(4) driver has been removed. This driver was for PCI-X 10g 445 cards made by s2io/Neterion. The company was acquired by Exar and 446 no longer sells or supports Ethernet products. If you have device 447 nxge in your kernel config file it must be removed. 448 44920180504: 450 The tz database (tzdb) has been updated to 2018e. This version more 451 correctly models time stamps in time zones with negative DST such as 452 Europe/Dublin (from 1971 on), Europe/Prague (1946/7), and 453 Africa/Windhoek (1994/2017). This does not affect the UT offsets, only 454 time zone abbreviations and the tm_isdst flag. 455 45620180502: 457 The ixgb(4) driver has been removed. This driver was for an early and 458 uncommon legacy PCI 10GbE for a single ASIC, Intel 82597EX. Intel 459 quickly shifted to the long lived ixgbe family. If you have device 460 ixgb in your kernel config file it must be removed. 461 46220180501: 463 The lmc(4) driver has been removed. This was a WAN interface 464 card that was already reportedly rare in 2003, and had an ambiguous 465 license. If you have device lmc in your kernel config file it must 466 be removed. 467 46820180413: 469 Support for Arcnet networks has been removed. If you have device 470 arcnet or device cm in your kernel config file they must be 471 removed. 472 47320180411: 474 Support for FDDI networks has been removed. If you have device 475 fddi or device fpa in your kernel config file they must be 476 removed. 477 47820180406: 479 In addition to supporting RFC 3164 formatted messages, the 480 syslogd(8) service is now capable of parsing RFC 5424 formatted 481 log messages. The main benefit of using RFC 5424 is that clients 482 may now send log messages with timestamps containing year numbers, 483 microseconds and time zone offsets. 484 485 Similarly, the syslog(3) C library function has been altered to 486 send RFC 5424 formatted messages to the local system logging 487 daemon. On systems using syslogd(8), this change should have no 488 negative impact, as long as syslogd(8) and the C library are 489 updated at the same time. On systems using a different system 490 logging daemon, it may be necessary to make configuration 491 adjustments, depending on the software used. 492 493 When using syslog-ng, add the 'syslog-protocol' flag to local 494 input sources to enable parsing of RFC 5424 formatted messages: 495 496 source src { 497 unix-dgram("/var/run/log" flags(syslog-protocol)); 498 } 499 500 When using rsyslog, disable the 'SysSock.UseSpecialParser' option 501 of the 'imuxsock' module to let messages be processed by the 502 regular RFC 3164/5424 parsing pipeline: 503 504 module(load="imuxsock" SysSock.UseSpecialParser="off") 505 506 Do note that these changes only affect communication between local 507 applications and syslogd(8). The format that syslogd(8) uses to 508 store messages on disk or forward messages to other systems 509 remains unchanged. syslogd(8) still uses RFC 3164 for these 510 purposes. Options to customize this behaviour will be added in the 511 future. Utilities that process log files stored in /var/log are 512 thus expected to continue to function as before. 513 514 __FreeBSD_version has been incremented to 1200061 to denote this 515 change. 516 51720180328: 518 Support for token ring networks has been removed. If you 519 have "device token" in your kernel config you should remove 520 it. No device drivers supported token ring. 521 52220180323: 523 makefs was modified to be able to tag ISO9660 El Torito boot catalog 524 entries as EFI instead of overloading the i386 tag as done previously. 525 The amd64 mkisoimages.sh script used to build amd64 ISO images for 526 release was updated to use this. This may mean that makefs must be 527 updated before "make cdrom" can be run in the release directory. This 528 should be as simple as: 529 530 $ cd $SRCDIR/usr.sbin/makefs 531 $ make depend all install 532 53320180212: 534 FreeBSD boot loader enhanced with Lua scripting. It's purely opt-in for 535 now by building WITH_LOADER_LUA and WITHOUT_FORTH in /etc/src.conf. 536 Co-existence for the transition period will come shortly. Booting is a 537 complex environment and test coverage for Lua-enabled loaders has been 538 thin, so it would be prudent to assume it might not work and make 539 provisions for backup boot methods. 540 54120180211: 542 devmatch functionality has been turned on in devd. It will automatically 543 load drivers for unattached devices. This may cause unexpected drivers 544 to be loaded. Please report any problems to current@ and 545 imp@freebsd.org. 546 54720180114: 548 Clang, llvm, lld, lldb, compiler-rt and libc++ have been upgraded to 549 6.0.0. Please see the 20141231 entry below for information about 550 prerequisites and upgrading, if you are not already using clang 3.5.0 551 or higher. 552 55320180110: 554 LLVM's lld linker is now used as the FreeBSD/amd64 bootstrap linker. 555 This means it is used to link the kernel and userland libraries and 556 executables, but is not yet installed as /usr/bin/ld by default. 557 558 To revert to ld.bfd as the bootstrap linker, in /etc/src.conf set 559 WITHOUT_LLD_BOOTSTRAP=yes 560 56120180110: 562 On i386, pmtimer has been removed. Its functionality has been folded 563 into apm. It was a no-op on ACPI in current for a while now (but was 564 still needed on i386 in FreeBSD 11 and earlier). Users may need to 565 remove it from kernel config files. 566 56720180104: 568 The use of RSS hash from the network card aka flowid has been 569 disabled by default for lagg(4) as it's currently incompatible with 570 the lacp and loadbalance protocols. 571 572 This can be re-enabled by setting the following in loader.conf: 573 net.link.lagg.default_use_flowid="1" 574 57520180102: 576 The SW_WATCHDOG option is no longer necessary to enable the 577 hardclock-based software watchdog if no hardware watchdog is 578 configured. As before, SW_WATCHDOG will cause the software 579 watchdog to be enabled even if a hardware watchdog is configured. 580 58120171215: 582 r326887 fixes the issue described in the 20171214 UPDATING entry. 583 r326888 flips the switch back to building GELI support always. 584 58520171214: 586 r362593 broke ZFS + GELI support for reasons unknown. However, 587 it also broke ZFS support generally, so GELI has been turned off 588 by default as the lesser evil in r326857. If you boot off ZFS and/or 589 GELI, it might not be a good time to update. 590 59120171125: 592 PowerPC users must update loader(8) by rebuilding world before 593 installing a new kernel, as the protocol connecting them has 594 changed. Without the update, loader metadata will not be passed 595 successfully to the kernel and users will have to enter their 596 root partition at the kernel mountroot prompt to continue booting. 597 Newer versions of loader can boot old kernels without issue. 598 59920171110: 600 The LOADER_FIREWIRE_SUPPORT build variable as been renamed to 601 WITH/OUT_LOADER_FIREWIRE. LOADER_{NO_,}GELI_SUPPORT has been renamed 602 to WITH/OUT_LOADER_GELI. 603 60420171106: 605 The naive and non-compliant support of posix_fallocate(2) in ZFS 606 has been removed as of r325320. The system call now returns EINVAL 607 when used on a ZFS file. Although the new behavior complies with the 608 standard, some consumers are not prepared to cope with it. 609 One known victim is lld prior to r325420. 610 61120171102: 612 Building in a FreeBSD src checkout will automatically create object 613 directories now rather than store files in the current directory if 614 'make obj' was not ran. Calling 'make obj' is no longer necessary. 615 This feature can be disabled by setting WITHOUT_AUTO_OBJ=yes in 616 /etc/src-env.conf (not /etc/src.conf), or passing the option in the 617 environment. 618 61920171101: 620 The default MAKEOBJDIR has changed from /usr/obj/<srcdir> for native 621 builds, and /usr/obj/<arch>/<srcdir> for cross-builds, to a unified 622 /usr/obj/<srcdir>/<arch>. This behavior can be changed to the old 623 format by setting WITHOUT_UNIFIED_OBJDIR=yes in /etc/src-env.conf, 624 the environment, or with -DWITHOUT_UNIFIED_OBJDIR when building. 625 The UNIFIED_OBJDIR option is a transitional feature that will be 626 removed for 12.0 release; please migrate to the new format for any 627 tools by looking up the OBJDIR used by 'make -V .OBJDIR' means rather 628 than hardcoding paths. 629 63020171028: 631 The native-xtools target no longer installs the files by default to the 632 OBJDIR. Use the native-xtools-install target with a DESTDIR to install 633 to ${DESTDIR}/${NXTP} where NXTP defaults to /nxb-bin. 634 63520171021: 636 As part of the boot loader infrastructure cleanup, LOADER_*_SUPPORT 637 options are changing from controlling the build if defined / undefined 638 to controlling the build with explicit 'yes' or 'no' values. They will 639 shift to WITH/WITHOUT options to match other options in the system. 640 64120171010: 642 libstand has turned into a private library for sys/boot use only. 643 It is no longer supported as a public interface outside of sys/boot. 644 64520171005: 646 The arm port has split armv6 into armv6 and armv7. armv7 is now 647 a valid TARGET_ARCH/MACHINE_ARCH setting. If you have an armv7 system 648 and are running a kernel from before r324363, you will need to add 649 MACHINE_ARCH=armv7 to 'make buildworld' to do a native build. 650 65120171003: 652 When building multiple kernels using KERNCONF, non-existent KERNCONF 653 files will produce an error and buildkernel will fail. Previously 654 missing KERNCONF files silently failed giving no indication as to 655 why, only to subsequently discover during installkernel that the 656 desired kernel was never built in the first place. 657 65820170912: 659 The default serial number format for CTL LUNs has changed. This will 660 affect users who use /dev/diskid/* device nodes, or whose FibreChannel 661 or iSCSI clients care about their LUNs' serial numbers. Users who 662 require serial number stability should hardcode serial numbers in 663 /etc/ctl.conf . 664 66520170912: 666 For 32-bit arm compiled for hard-float support, soft-floating point 667 binaries now always get their shared libraries from 668 LD_SOFT_LIBRARY_PATH (in the past, this was only used if 669 /usr/libsoft also existed). Only users with a hard-float ld.so, but 670 soft-float everything else should be affected. 671 67220170826: 673 The geli password typed at boot is now hidden. To restore the previous 674 behavior, see geli(8) for configuration options. 675 67620170825: 677 Move PMTUD blackhole counters to TCPSTATS and remove them from bare 678 sysctl values. Minor nit, but requires a rebuild of both world/kernel 679 to complete. 680 68120170814: 682 "make check" behavior (made in ^/head@r295380) has been changed to 683 execute from a limited sandbox, as opposed to executing from 684 ${TESTSDIR}. 685 686 Behavioral changes: 687 - The "beforecheck" and "aftercheck" targets are now specified. 688 - ${CHECKDIR} (added in commit noted above) has been removed. 689 - Legacy behavior can be enabled by setting 690 WITHOUT_MAKE_CHECK_USE_SANDBOX in src.conf(5) or the environment. 691 692 If the limited sandbox mode is enabled, "make check" will execute 693 "make distribution", then install, execute the tests, and clean up the 694 sandbox if successful. 695 696 The "make distribution" and "make install" targets are typically run as 697 root to set appropriate permissions and ownership at installation time. 698 The end-user should set "WITH_INSTALL_AS_USER" in src.conf(5) or the 699 environment if executing "make check" with limited sandbox mode using 700 an unprivileged user. 701 70220170808: 703 Since the switch to GPT disk labels, fsck for UFS/FFS has been 704 unable to automatically find alternate superblocks. As of r322297, 705 the information needed to find alternate superblocks has been 706 moved to the end of the area reserved for the boot block. 707 Filesystems created with a newfs of this vintage or later 708 will create the recovery information. If you have a filesystem 709 created prior to this change and wish to have a recovery block 710 created for your filesystem, you can do so by running fsck in 711 foreground mode (i.e., do not use the -p or -y options). As it 712 starts, fsck will ask ``SAVE DATA TO FIND ALTERNATE SUPERBLOCKS'' 713 to which you should answer yes. 714 71520170728: 716 As of r321665, an NFSv4 server configuration that services 717 Kerberos mounts or clients that do not support the uid/gid in 718 owner/owner_group string capability, must explicitly enable 719 the nfsuserd daemon by adding nfsuserd_enable="YES" to the 720 machine's /etc/rc.conf file. 721 72220170722: 723 Clang, llvm, lldb, compiler-rt and libc++ have been upgraded to 5.0.0. 724 Please see the 20141231 entry below for information about prerequisites 725 and upgrading, if you are not already using clang 3.5.0 or higher. 726 72720170701: 728 WITHOUT_RCMDS is now the default. Set WITH_RCMDS if you need the 729 r-commands (rlogin, rsh, etc.) to be built with the base system. 730 73120170625: 732 The FreeBSD/powerpc platform now uses a 64-bit type for time_t. This is 733 a very major ABI incompatible change, so users of FreeBSD/powerpc must 734 be careful when performing source upgrades. It is best to run 735 'make installworld' from an alternate root system, either a live 736 CD/memory stick, or a temporary root partition. Additionally, all ports 737 must be recompiled. powerpc64 is largely unaffected, except in the case 738 of 32-bit compatibility. All 32-bit binaries will be affected. 739 74020170623: 741 Forward compatibility for the "ino64" project have been committed. This 742 will allow most new binaries to run on older kernels in a limited 743 fashion. This prevents many of the common foot-shooting actions in the 744 upgrade as well as the limited ability to roll back the kernel across 745 the ino64 upgrade. Complicated use cases may not work properly, though 746 enough simpler ones work to allow recovery in most situations. 747 74820170620: 749 Switch back to the BSDL dtc (Device Tree Compiler). Set WITH_GPL_DTC 750 if you require the GPL compiler. 751 75220170618: 753 The internal ABI used for communication between the NFS kernel modules 754 was changed by r320085, so __FreeBSD_version was bumped to 755 ensure all the NFS related modules are updated together. 756 75720170617: 758 The ABI of struct event was changed by extending the data 759 member to 64bit and adding ext fields. For upgrade, same 760 precautions as for the entry 20170523 "ino64" must be 761 followed. 762 76320170531: 764 The GNU roff toolchain has been removed from base. To render manpages 765 which are not supported by mandoc(1), man(1) can fallback on GNU roff 766 from ports (and recommends to install it). 767 To render roff(7) documents, consider using GNU roff from ports or the 768 heirloom doctools roff toolchain from ports via pkg install groff or 769 via pkg install heirloom-doctools. 770 77120170524: 772 The ath(4) and ath_hal(4) modules now build piecemeal to allow for 773 smaller runtime footprint builds. This is useful for embedded systems 774 which only require one chipset support. 775 776 If you load it as a module, make sure this is in /boot/loader.conf: 777 778 if_ath_load="YES" 779 780 This will load the HAL, all chip/RF backends and if_ath_pci. 781 If you have if_ath_pci in /boot/loader.conf, ensure it is after 782 if_ath or it will not load any HAL chipset support. 783 784 If you want to selectively load things (eg on ye cheape ARM/MIPS 785 platforms where RAM is at a premium) you should: 786 787 * load ath_hal 788 * load the chip modules in question 789 * load ath_rate, ath_dfs 790 * load ath_main 791 * load if_ath_pci and/or if_ath_ahb depending upon your particular 792 bus bind type - this is where probe/attach is done. 793 794 For further comments/feedback, poke adrian@ . 795 79620170523: 797 The "ino64" 64-bit inode project has been committed, which extends 798 a number of types to 64 bits. Upgrading in place requires care and 799 adherence to the documented upgrade procedure. 800 801 If using a custom kernel configuration ensure that the 802 COMPAT_FREEBSD11 option is included (as during the upgrade the 803 system will be running the ino64 kernel with the existing world). 804 805 For the safest in-place upgrade begin by removing previous build 806 artifacts via "rm -rf /usr/obj/*". Then, carefully follow the full 807 procedure documented below under the heading "To rebuild everything and 808 install it on the current system." Specifically, a reboot is required 809 after installing the new kernel before installing world. While an 810 installworld normally works by accident from multiuser after rebooting 811 the proper kernel, there are many cases where this will fail across this 812 upgrade and installworld from single user is required. 813 81420170424: 815 The NATM framework including the en(4), fatm(4), hatm(4), and 816 patm(4) devices has been removed. Consumers should plan a 817 migration before the end-of-life date for FreeBSD 11. 818 81920170420: 820 GNU diff has been replaced by a BSD licensed diff. Some features of GNU 821 diff has not been implemented, if those are needed a newer version of 822 GNU diff is available via the diffutils package under the gdiff name. 823 82420170413: 825 As of r316810 for ipfilter, keep frags is no longer assumed when 826 keep state is specified in a rule. r316810 aligns ipfilter with 827 documentation in man pages separating keep frags from keep state. 828 This allows keep state to be specified without forcing keep frags 829 and allows keep frags to be specified independently of keep state. 830 To maintain previous behaviour, also specify keep frags with 831 keep state (as documented in ipf.conf.5). 832 83320170407: 834 arm64 builds now use the base system LLD 4.0.0 linker by default, 835 instead of requiring that the aarch64-binutils port or package be 836 installed. To continue using aarch64-binutils, set 837 CROSS_BINUTILS_PREFIX=/usr/local/aarch64-freebsd/bin . 838 83920170405: 840 The UDP optimization in entry 20160818 that added the sysctl 841 net.inet.udp.require_l2_bcast has been reverted. L2 broadcast 842 packets will no longer be treated as L3 broadcast packets. 843 84420170331: 845 Binds and sends to the loopback addresses, IPv6 and IPv4, will now 846 use any explicitly assigned loopback address available in the jail 847 instead of using the first assigned address of the jail. 848 84920170329: 850 The ctl.ko module no longer implements the iSCSI target frontend: 851 cfiscsi.ko does instead. 852 853 If building cfiscsi.ko as a kernel module, the module can be loaded 854 via one of the following methods: 855 - `cfiscsi_load="YES"` in loader.conf(5). 856 - Add `cfiscsi` to `$kld_list` in rc.conf(5). 857 - ctladm(8)/ctld(8), when compiled with iSCSI support 858 (`WITH_ISCSI=yes` in src.conf(5)) 859 860 Please see cfiscsi(4) for more details. 861 86220170316: 863 The mmcsd.ko module now additionally depends on geom_flashmap.ko. 864 Also, mmc.ko and mmcsd.ko need to be a matching pair built from the 865 same source (previously, the dependency of mmcsd.ko on mmc.ko was 866 missing, but mmcsd.ko now will refuse to load if it is incompatible 867 with mmc.ko). 868 86920170315: 870 The syntax of ipfw(8) named states was changed to avoid ambiguity. 871 If you have used named states in the firewall rules, you need to modify 872 them after installworld and before rebooting. Now named states must 873 be prefixed with colon. 874 87520170311: 876 The old drm (sys/dev/drm/) drivers for i915 and radeon have been 877 removed as the userland we provide cannot use them. The KMS version 878 (sys/dev/drm2) supports the same hardware. 879 88020170302: 881 Clang, llvm, lldb, compiler-rt and libc++ have been upgraded to 4.0.0. 882 Please see the 20141231 entry below for information about prerequisites 883 and upgrading, if you are not already using clang 3.5.0 or higher. 884 88520170221: 886 The code that provides support for ZFS .zfs/ directory functionality 887 has been reimplemented. It's not possible now to create a snapshot 888 by mkdir under .zfs/snapshot/. That should be the only user visible 889 change. 890 89120170216: 892 EISA bus support has been removed. The WITH_EISA option is no longer 893 valid. 894 89520170215: 896 MCA bus support has been removed. 897 89820170127: 899 The WITH_LLD_AS_LD / WITHOUT_LLD_AS_LD build knobs have been renamed 900 WITH_LLD_IS_LD / WITHOUT_LLD_IS_LD, for consistency with CLANG_IS_CC. 901 90220170112: 903 The EM_MULTIQUEUE kernel configuration option is deprecated now that 904 the em(4) driver conforms to iflib specifications. 905 90620170109: 907 The igb(4), em(4) and lem(4) ethernet drivers are now implemented via 908 IFLIB. If you have a custom kernel configuration that excludes em(4) 909 but you use igb(4), you need to re-add em(4) to your custom 910 configuration. 911 91220161217: 913 Clang, llvm, lldb, compiler-rt and libc++ have been upgraded to 3.9.1. 914 Please see the 20141231 entry below for information about prerequisites 915 and upgrading, if you are not already using clang 3.5.0 or higher. 916 91720161124: 918 Clang, llvm, lldb, compiler-rt and libc++ have been upgraded to 3.9.0. 919 Please see the 20141231 entry below for information about prerequisites 920 and upgrading, if you are not already using clang 3.5.0 or higher. 921 92220161119: 923 The layout of the pmap structure has changed for powerpc to put the pmap 924 statistics at the front for all CPU variations. libkvm(3) and all tools 925 that link against it need to be recompiled. 926 92720161030: 928 isl(4) and cyapa(4) drivers now require a new driver, 929 chromebook_platform(4), to work properly on Chromebook-class hardware. 930 On other types of hardware the drivers may need to be configured using 931 device hints. Please see the corresponding manual pages for details. 932 93320161017: 934 The urtwn(4) driver was merged into rtwn(4) and now consists of 935 rtwn(4) main module + rtwn_usb(4) and rtwn_pci(4) bus-specific 936 parts. 937 Also, firmware for RTL8188CE was renamed due to possible name 938 conflict (rtwnrtl8192cU(B) -> rtwnrtl8192cE(B)) 939 94020161015: 941 GNU rcs has been removed from base. It is available as packages: 942 - rcs: Latest GPLv3 GNU rcs version. 943 - rcs57: Copy of the latest version of GNU rcs (GPLv2) before it was 944 removed from base. 945 94620161008: 947 Use of the cc_cdg, cc_chd, cc_hd, or cc_vegas congestion control 948 modules now requires that the kernel configuration contain the 949 TCP_HHOOK option. (This option is included in the GENERIC kernel.) 950 95120161003: 952 The WITHOUT_ELFCOPY_AS_OBJCOPY src.conf(5) knob has been retired. 953 ELF Tool Chain's elfcopy is always installed as /usr/bin/objcopy. 954 95520160924: 956 Relocatable object files with the extension of .So have been renamed 957 to use an extension of .pico instead. The purpose of this change is 958 to avoid a name clash with shared libraries on case-insensitive file 959 systems. On those file systems, foo.So is the same file as foo.so. 960 96120160918: 962 GNU rcs has been turned off by default. It can (temporarily) be built 963 again by adding WITH_RCS knob in src.conf. 964 Otherwise, GNU rcs is available from packages: 965 - rcs: Latest GPLv3 GNU rcs version. 966 - rcs57: Copy of the latest version of GNU rcs (GPLv2) from base. 967 96820160918: 969 The backup_uses_rcs functionality has been removed from rc.subr. 970 97120160908: 972 The queue(3) debugging macro, QUEUE_MACRO_DEBUG, has been split into 973 two separate components, QUEUE_MACRO_DEBUG_TRACE and 974 QUEUE_MACRO_DEBUG_TRASH. Define both for the original 975 QUEUE_MACRO_DEBUG behavior. 976 97720160824: 978 r304787 changed some ioctl interfaces between the iSCSI userspace 979 programs and the kernel. ctladm, ctld, iscsictl, and iscsid must be 980 rebuilt to work with new kernels. __FreeBSD_version has been bumped 981 to 1200005. 982 98320160818: 984 The UDP receive code has been updated to only treat incoming UDP 985 packets that were addressed to an L2 broadcast address as L3 986 broadcast packets. It is not expected that this will affect any 987 standards-conforming UDP application. The new behaviour can be 988 disabled by setting the sysctl net.inet.udp.require_l2_bcast to 989 0. 990 99120160818: 992 Remove the openbsd_poll system call. 993 __FreeBSD_version has been bumped because of this. 994 99520160708: 996 The stable/11 branch has been created from head@r302406. 997 99820160622: 999 The libc stub for the pipe(2) system call has been replaced with 1000 a wrapper that calls the pipe2(2) system call and the pipe(2) 1001 system call is now only implemented by the kernels that include 1002 "options COMPAT_FREEBSD10" in their config file (this is the 1003 default). Users should ensure that this option is enabled in 1004 their kernel or upgrade userspace to r302092 before upgrading their 1005 kernel. 1006 100720160527: 1008 CAM will now strip leading spaces from SCSI disks' serial numbers. 1009 This will affect users who create UFS filesystems on SCSI disks using 1010 those disk's diskid device nodes. For example, if /etc/fstab 1011 previously contained a line like 1012 "/dev/diskid/DISK-%20%20%20%20%20%20%20ABCDEFG0123456", you should 1013 change it to "/dev/diskid/DISK-ABCDEFG0123456". Users of geom 1014 transforms like gmirror may also be affected. ZFS users should 1015 generally be fine. 1016 101720160523: 1018 The bitstring(3) API has been updated with new functionality and 1019 improved performance. But it is binary-incompatible with the old API. 1020 Objects built with the new headers may not be linked against objects 1021 built with the old headers. 1022 102320160520: 1024 The brk and sbrk functions have been removed from libc on arm64. 1025 Binutils from ports has been updated to not link to these 1026 functions and should be updated to the latest version before 1027 installing a new libc. 1028 102920160517: 1030 The armv6 port now defaults to hard float ABI. Limited support 1031 for running both hardfloat and soft float on the same system 1032 is available using the libraries installed with -DWITH_LIBSOFT. 1033 This has only been tested as an upgrade path for installworld 1034 and packages may fail or need manual intervention to run. New 1035 packages will be needed. 1036 1037 To update an existing self-hosted armv6hf system, you must add 1038 TARGET_ARCH=armv6 on the make command line for both the build 1039 and the install steps. 1040 104120160510: 1042 Kernel modules compiled outside of a kernel build now default to 1043 installing to /boot/modules instead of /boot/kernel. Many kernel 1044 modules built this way (such as those in ports) already overrode 1045 KMODDIR explicitly to install into /boot/modules. However, 1046 manually building and installing a module from /sys/modules will 1047 now install to /boot/modules instead of /boot/kernel. 1048 104920160414: 1050 The CAM I/O scheduler has been committed to the kernel. There should be 1051 no user visible impact. This does enable NCQ Trim on ada SSDs. While the 1052 list of known rogues that claim support for this but actually corrupt 1053 data is believed to be complete, be on the lookout for data 1054 corruption. The known rogue list is believed to be complete: 1055 1056 o Crucial MX100, M550 drives with MU01 firmware. 1057 o Micron M510 and M550 drives with MU01 firmware. 1058 o Micron M500 prior to MU07 firmware 1059 o Samsung 830, 840, and 850 all firmwares 1060 o FCCT M500 all firmwares 1061 1062 Crucial has firmware http://www.crucial.com/usa/en/support-ssd-firmware 1063 with working NCQ TRIM. For Micron branded drives, see your sales rep for 1064 updated firmware. Black listed drives will work correctly because these 1065 drives work correctly so long as no NCQ TRIMs are sent to them. Given 1066 this list is the same as found in Linux, it's believed there are no 1067 other rogues in the market place. All other models from the above 1068 vendors work. 1069 1070 To be safe, if you are at all concerned, you can quirk each of your 1071 drives to prevent NCQ from being sent by setting: 1072 kern.cam.ada.X.quirks="0x2" 1073 in loader.conf. If the drive requires the 4k sector quirk, set the 1074 quirks entry to 0x3. 1075 107620160330: 1077 The FAST_DEPEND build option has been removed and its functionality is 1078 now the one true way. The old mkdep(1) style of 'make depend' has 1079 been removed. See 20160311 for further details. 1080 108120160317: 1082 Resource range types have grown from unsigned long to uintmax_t. All 1083 drivers, and anything using libdevinfo, need to be recompiled. 1084 108520160311: 1086 WITH_FAST_DEPEND is now enabled by default for in-tree and out-of-tree 1087 builds. It no longer runs mkdep(1) during 'make depend', and the 1088 'make depend' stage can safely be skipped now as it is auto ran 1089 when building 'make all' and will generate all SRCS and DPSRCS before 1090 building anything else. Dependencies are gathered at compile time with 1091 -MF flags kept in separate .depend files per object file. Users should 1092 run 'make cleandepend' once if using -DNO_CLEAN to clean out older 1093 stale .depend files. 1094 109520160306: 1096 On amd64, clang 3.8.0 can now insert sections of type AMD64_UNWIND into 1097 kernel modules. Therefore, if you load any kernel modules at boot time, 1098 please install the boot loaders after you install the kernel, but before 1099 rebooting, e.g.: 1100 1101 make buildworld 1102 make buildkernel KERNCONF=YOUR_KERNEL_HERE 1103 make installkernel KERNCONF=YOUR_KERNEL_HERE 1104 make -C sys/boot install 1105 <reboot in single user> 1106 1107 Then follow the usual steps, described in the General Notes section, 1108 below. 1109 111020160305: 1111 Clang, llvm, lldb and compiler-rt have been upgraded to 3.8.0. Please 1112 see the 20141231 entry below for information about prerequisites and 1113 upgrading, if you are not already using clang 3.5.0 or higher. 1114 111520160301: 1116 The AIO subsystem is now a standard part of the kernel. The 1117 VFS_AIO kernel option and aio.ko kernel module have been removed. 1118 Due to stability concerns, asynchronous I/O requests are only 1119 permitted on sockets and raw disks by default. To enable 1120 asynchronous I/O requests on all file types, set the 1121 vfs.aio.enable_unsafe sysctl to a non-zero value. 1122 112320160226: 1124 The ELF object manipulation tool objcopy is now provided by the 1125 ELF Tool Chain project rather than by GNU binutils. It should be a 1126 drop-in replacement, with the addition of arm64 support. The 1127 (temporary) src.conf knob WITHOUT_ELFCOPY_AS_OBJCOPY knob may be set 1128 to obtain the GNU version if necessary. 1129 113020160129: 1131 Building ZFS pools on top of zvols is prohibited by default. That 1132 feature has never worked safely; it's always been prone to deadlocks. 1133 Using a zvol as the backing store for a VM guest's virtual disk will 1134 still work, even if the guest is using ZFS. Legacy behavior can be 1135 restored by setting vfs.zfs.vol.recursive=1. 1136 113720160119: 1138 The NONE and HPN patches has been removed from OpenSSH. They are 1139 still available in the security/openssh-portable port. 1140 114120160113: 1142 With the addition of ypldap(8), a new _ypldap user is now required 1143 during installworld. "mergemaster -p" can be used to add the user 1144 prior to installworld, as documented in the handbook. 1145 114620151216: 1147 The tftp loader (pxeboot) now uses the option root-path directive. As a 1148 consequence it no longer looks for a pxeboot.4th file on the tftp 1149 server. Instead it uses the regular /boot infrastructure as with the 1150 other loaders. 1151 115220151211: 1153 The code to start recording plug and play data into the modules has 1154 been committed. While the old tools will properly build a new kernel, 1155 a number of warnings about "unknown metadata record 4" will be produced 1156 for an older kldxref. To avoid such warnings, make sure to rebuild 1157 the kernel toolchain (or world). Make sure that you have r292078 or 1158 later when trying to build 292077 or later before rebuilding. 1159 116020151207: 1161 Debug data files are now built by default with 'make buildworld' and 1162 installed with 'make installworld'. This facilitates debugging but 1163 requires more disk space both during the build and for the installed 1164 world. Debug files may be disabled by setting WITHOUT_DEBUG_FILES=yes 1165 in src.conf(5). 1166 116720151130: 1168 r291527 changed the internal interface between the nfsd.ko and 1169 nfscommon.ko modules. As such, they must both be upgraded to-gether. 1170 __FreeBSD_version has been bumped because of this. 1171 117220151108: 1173 Add support for unicode collation strings leads to a change of 1174 order of files listed by ls(1) for example. To get back to the old 1175 behaviour, set LC_COLLATE environment variable to "C". 1176 1177 Databases administrators will need to reindex their databases given 1178 collation results will be different. 1179 1180 Due to a bug in install(1) it is recommended to remove the ancient 1181 locales before running make installworld. 1182 1183 rm -rf /usr/share/locale/* 1184 118520151030: 1186 The OpenSSL has been upgraded to 1.0.2d. Any binaries requiring 1187 libcrypto.so.7 or libssl.so.7 must be recompiled. 1188 118920151020: 1190 Qlogic 24xx/25xx firmware images were updated from 5.5.0 to 7.3.0. 1191 Kernel modules isp_2400_multi and isp_2500_multi were removed and 1192 should be replaced with isp_2400 and isp_2500 modules respectively. 1193 119420151017: 1195 The build previously allowed using 'make -n' to not recurse into 1196 sub-directories while showing what commands would be executed, and 1197 'make -n -n' to recursively show commands. Now 'make -n' will recurse 1198 and 'make -N' will not. 1199 120020151012: 1201 If you specify SENDMAIL_MC or SENDMAIL_CF in make.conf, mergemaster 1202 and etcupdate will now use this file. A custom sendmail.cf is now 1203 updated via this mechanism rather than via installworld. If you had 1204 excluded sendmail.cf in mergemaster.rc or etcupdate.conf, you may 1205 want to remove the exclusion or change it to "always install". 1206 /etc/mail/sendmail.cf is now managed the same way regardless of 1207 whether SENDMAIL_MC/SENDMAIL_CF is used. If you are not using 1208 SENDMAIL_MC/SENDMAIL_CF there should be no change in behavior. 1209 121020151011: 1211 Compatibility shims for legacy ATA device names have been removed. 1212 It includes ATA_STATIC_ID kernel option, kern.cam.ada.legacy_aliases 1213 and kern.geom.raid.legacy_aliases loader tunables, kern.devalias.* 1214 environment variables, /dev/ad* and /dev/ar* symbolic links. 1215 121620151006: 1217 Clang, llvm, lldb, compiler-rt and libc++ have been upgraded to 3.7.0. 1218 Please see the 20141231 entry below for information about prerequisites 1219 and upgrading, if you are not already using clang 3.5.0 or higher. 1220 122120150924: 1222 Kernel debug files have been moved to /usr/lib/debug/boot/kernel/, 1223 and renamed from .symbols to .debug. This reduces the size requirements 1224 on the boot partition or file system and provides consistency with 1225 userland debug files. 1226 1227 When using the supported kernel installation method the 1228 /usr/lib/debug/boot/kernel directory will be renamed (to kernel.old) 1229 as is done with /boot/kernel. 1230 1231 Developers wishing to maintain the historical behavior of installing 1232 debug files in /boot/kernel/ can set KERN_DEBUGDIR="" in src.conf(5). 1233 123420150827: 1235 The wireless drivers had undergone changes that remove the 'parent 1236 interface' from the ifconfig -l output. The rc.d network scripts 1237 used to check presence of a parent interface in the list, so old 1238 scripts would fail to start wireless networking. Thus, etcupdate(3) 1239 or mergemaster(8) run is required after kernel update, to update your 1240 rc.d scripts in /etc. 1241 124220150827: 1243 pf no longer supports 'scrub fragment crop' or 'scrub fragment drop-ovl' 1244 These configurations are now automatically interpreted as 1245 'scrub fragment reassemble'. 1246 124720150817: 1248 Kernel-loadable modules for the random(4) device are back. To use 1249 them, the kernel must have 1250 1251 device random 1252 options RANDOM_LOADABLE 1253 1254 kldload(8) can then be used to load random_fortuna.ko 1255 or random_yarrow.ko. Please note that due to the indirect 1256 function calls that the loadable modules need to provide, 1257 the build-in variants will be slightly more efficient. 1258 1259 The random(4) kernel option RANDOM_DUMMY has been retired due to 1260 unpopularity. It was not all that useful anyway. 1261 126220150813: 1263 The WITHOUT_ELFTOOLCHAIN_TOOLS src.conf(5) knob has been retired. 1264 Control over building the ELF Tool Chain tools is now provided by 1265 the WITHOUT_TOOLCHAIN knob. 1266 126720150810: 1268 The polarity of Pulse Per Second (PPS) capture events with the 1269 uart(4) driver has been corrected. Prior to this change the PPS 1270 "assert" event corresponded to the trailing edge of a positive PPS 1271 pulse and the "clear" event was the leading edge of the next pulse. 1272 1273 As the width of a PPS pulse in a typical GPS receiver is on the 1274 order of 1 millisecond, most users will not notice any significant 1275 difference with this change. 1276 1277 Anyone who has compensated for the historical polarity reversal by 1278 configuring a negative offset equal to the pulse width will need to 1279 remove that workaround. 1280 128120150809: 1282 The default group assigned to /dev/dri entries has been changed 1283 from 'wheel' to 'video' with the id of '44'. If you want to have 1284 access to the dri devices please add yourself to the video group 1285 with: 1286 1287 # pw groupmod video -m $USER 1288 128920150806: 1290 The menu.rc and loader.rc files will now be replaced during 1291 upgrades. Please migrate local changes to menu.rc.local and 1292 loader.rc.local instead. 1293 129420150805: 1295 GNU Binutils versions of addr2line, c++filt, nm, readelf, size, 1296 strings and strip have been removed. The src.conf(5) knob 1297 WITHOUT_ELFTOOLCHAIN_TOOLS no longer provides the binutils tools. 1298 129920150728: 1300 As ZFS requires more kernel stack pages than is the default on some 1301 architectures e.g. i386, it now warns if KSTACK_PAGES is less than 1302 ZFS_MIN_KSTACK_PAGES (which is 4 at the time of writing). 1303 1304 Please consider using 'options KSTACK_PAGES=X' where X is greater 1305 than or equal to ZFS_MIN_KSTACK_PAGES i.e. 4 in such configurations. 1306 130720150706: 1308 sendmail has been updated to 8.15.2. Starting with FreeBSD 11.0 1309 and sendmail 8.15, sendmail uses uncompressed IPv6 addresses by 1310 default, i.e., they will not contain "::". For example, instead 1311 of ::1, it will be 0:0:0:0:0:0:0:1. This permits a zero subnet 1312 to have a more specific match, such as different map entries for 1313 IPv6:0:0 vs IPv6:0. This change requires that configuration 1314 data (including maps, files, classes, custom ruleset, etc.) must 1315 use the same format, so make certain such configuration data is 1316 upgrading. As a very simple check search for patterns like 1317 'IPv6:[0-9a-fA-F:]*::' and 'IPv6::'. To return to the old 1318 behavior, set the m4 option confUSE_COMPRESSED_IPV6_ADDRESSES or 1319 the cf option UseCompressedIPv6Addresses. 1320 132120150630: 1322 The default kernel entropy-processing algorithm is now 1323 Fortuna, replacing Yarrow. 1324 1325 Assuming you have 'device random' in your kernel config 1326 file, the configurations allow a kernel option to override 1327 this default. You may choose *ONE* of: 1328 1329 options RANDOM_YARROW # Legacy /dev/random algorithm. 1330 options RANDOM_DUMMY # Blocking-only driver. 1331 1332 If you have neither, you get Fortuna. For most people, 1333 read no further, Fortuna will give a /dev/random that works 1334 like it always used to, and the difference will be irrelevant. 1335 1336 If you remove 'device random', you get *NO* kernel-processed 1337 entropy at all. This may be acceptable to folks building 1338 embedded systems, but has complications. Carry on reading, 1339 and it is assumed you know what you need. 1340 1341 *PLEASE* read random(4) and random(9) if you are in the 1342 habit of tweaking kernel configs, and/or if you are a member 1343 of the embedded community, wanting specific and not-usual 1344 behaviour from your security subsystems. 1345 1346 NOTE!! If you use RANDOM_DUMMY and/or have no 'device 1347 random', you will NOT have a functioning /dev/random, and 1348 many cryptographic features will not work, including SSH. 1349 You may also find strange behaviour from the random(3) set 1350 of library functions, in particular sranddev(3), srandomdev(3) 1351 and arc4random(3). The reason for this is that the KERN_ARND 1352 sysctl only returns entropy if it thinks it has some to 1353 share, and with RANDOM_DUMMY or no 'device random' this 1354 will never happen. 1355 135620150623: 1357 An additional fix for the issue described in the 20150614 sendmail 1358 entry below has been committed in revision 284717. 1359 136020150616: 1361 FreeBSD's old make (fmake) has been removed from the system. It is 1362 available as the devel/fmake port or via pkg install fmake. 1363 136420150615: 1365 The fix for the issue described in the 20150614 sendmail entry 1366 below has been committed in revision 284436. The work 1367 around described in that entry is no longer needed unless the 1368 default setting is overridden by a confDH_PARAMETERS configuration 1369 setting of '5' or pointing to a 512 bit DH parameter file. 1370 137120150614: 1372 ALLOW_DEPRECATED_ATF_TOOLS/ATFFILE support has been removed from 1373 atf.test.mk (included from bsd.test.mk). Please upgrade devel/atf 1374 and devel/kyua to version 0.20+ and adjust any calling code to work 1375 with Kyuafile and kyua. 1376 137720150614: 1378 The import of openssl to address the FreeBSD-SA-15:10.openssl 1379 security advisory includes a change which rejects handshakes 1380 with DH parameters below 768 bits. sendmail releases prior 1381 to 8.15.2 (not yet released), defaulted to a 512 bit 1382 DH parameter setting for client connections. To work around 1383 this interoperability, sendmail can be configured to use a 1384 2048 bit DH parameter by: 1385 1386 1. Edit /etc/mail/`hostname`.mc 1387 2. If a setting for confDH_PARAMETERS does not exist or 1388 exists and is set to a string beginning with '5', 1389 replace it with '2'. 1390 3. If a setting for confDH_PARAMETERS exists and is set to 1391 a file path, create a new file with: 1392 openssl dhparam -out /path/to/file 2048 1393 4. Rebuild the .cf file: 1394 cd /etc/mail/; make; make install 1395 5. Restart sendmail: 1396 cd /etc/mail/; make restart 1397 1398 A sendmail patch is coming, at which time this file will be 1399 updated. 1400 140120150604: 1402 Generation of legacy formatted entries have been disabled by default 1403 in pwd_mkdb(8), as all base system consumers of the legacy formatted 1404 entries were converted to use the new format by default when the new, 1405 machine independent format have been added and supported since FreeBSD 1406 5.x. 1407 1408 Please see the pwd_mkdb(8) manual page for further details. 1409 141020150525: 1411 Clang and llvm have been upgraded to 3.6.1 release. Please see the 1412 20141231 entry below for information about prerequisites and upgrading, 1413 if you are not already using 3.5.0 or higher. 1414 141520150521: 1416 TI platform code switched to using vendor DTS files and this update 1417 may break existing systems running on Beaglebone, Beaglebone Black, 1418 and Pandaboard: 1419 1420 - dtb files should be regenerated/reinstalled. Filenames are the 1421 same but content is different now 1422 - GPIO addressing was changed, now each GPIO bank (32 pins per bank) 1423 has its own /dev/gpiocX device, e.g. pin 121 on /dev/gpioc0 in old 1424 addressing scheme is now pin 25 on /dev/gpioc3. 1425 - Pandaboard: /etc/ttys should be updated, serial console device is 1426 now /dev/ttyu2, not /dev/ttyu0 1427 142820150501: 1429 soelim(1) from gnu/usr.bin/groff has been replaced by usr.bin/soelim. 1430 If you need the GNU extension from groff soelim(1), install groff 1431 from package: pkg install groff, or via ports: textproc/groff. 1432 143320150423: 1434 chmod, chflags, chown and chgrp now affect symlinks in -R mode as 1435 defined in symlink(7); previously symlinks were silently ignored. 1436 143720150415: 1438 The const qualifier has been removed from iconv(3) to comply with 1439 POSIX. The ports tree is aware of this from r384038 onwards. 1440 144120150416: 1442 Libraries specified by LIBADD in Makefiles must have a corresponding 1443 DPADD_<lib> variable to ensure correct dependencies. This is now 1444 enforced in src.libnames.mk. 1445 144620150324: 1447 From legacy ata(4) driver was removed support for SATA controllers 1448 supported by more functional drivers ahci(4), siis(4) and mvs(4). 1449 Kernel modules ataahci and ataadaptec were removed completely, 1450 replaced by ahci and mvs modules respectively. 1451 145220150315: 1453 Clang, llvm and lldb have been upgraded to 3.6.0 release. Please see 1454 the 20141231 entry below for information about prerequisites and 1455 upgrading, if you are not already using 3.5.0 or higher. 1456 145720150307: 1458 The 32-bit PowerPC kernel has been changed to a position-independent 1459 executable. This can only be booted with a version of loader(8) 1460 newer than January 31, 2015, so make sure to update both world and 1461 kernel before rebooting. 1462 146320150217: 1464 If you are running a -CURRENT kernel since r273872 (Oct 30th, 2014), 1465 but before r278950, the RNG was not seeded properly. Immediately 1466 upgrade the kernel to r278950 or later and regenerate any keys (e.g. 1467 ssh keys or openssl keys) that were generated w/ a kernel from that 1468 range. This does not affect programs that directly used /dev/random 1469 or /dev/urandom. All userland uses of arc4random(3) are affected. 1470 147120150210: 1472 The autofs(4) ABI was changed in order to restore binary compatibility 1473 with 10.1-RELEASE. The automountd(8) daemon needs to be rebuilt to work 1474 with the new kernel. 1475 147620150131: 1477 The powerpc64 kernel has been changed to a position-independent 1478 executable. This can only be booted with a new version of loader(8), 1479 so make sure to update both world and kernel before rebooting. 1480 148120150118: 1482 Clang and llvm have been upgraded to 3.5.1 release. This is a bugfix 1483 only release, no new features have been added. Please see the 20141231 1484 entry below for information about prerequisites and upgrading, if you 1485 are not already using 3.5.0. 1486 148720150107: 1488 ELF tools addr2line, elfcopy (strip), nm, size, and strings are now 1489 taken from the ELF Tool Chain project rather than GNU binutils. They 1490 should be drop-in replacements, with the addition of arm64 support. 1491 The WITHOUT_ELFTOOLCHAIN_TOOLS= knob may be used to obtain the 1492 binutils tools, if necessary. See 20150805 for updated information. 1493 149420150105: 1495 The default Unbound configuration now enables remote control 1496 using a local socket. Users who have already enabled the 1497 local_unbound service should regenerate their configuration 1498 by running "service local_unbound setup" as root. 1499 150020150102: 1501 The GNU texinfo and GNU info pages have been removed. 1502 To be able to view GNU info pages please install texinfo from ports. 1503 150420141231: 1505 Clang, llvm and lldb have been upgraded to 3.5.0 release. 1506 1507 As of this release, a prerequisite for building clang, llvm and lldb is 1508 a C++11 capable compiler and C++11 standard library. This means that to 1509 be able to successfully build the cross-tools stage of buildworld, with 1510 clang as the bootstrap compiler, your system compiler or cross compiler 1511 should either be clang 3.3 or later, or gcc 4.8 or later, and your 1512 system C++ library should be libc++, or libdstdc++ from gcc 4.8 or 1513 later. 1514 1515 On any standard FreeBSD 10.x or 11.x installation, where clang and 1516 libc++ are on by default (that is, on x86 or arm), this should work out 1517 of the box. 1518 1519 On 9.x installations where clang is enabled by default, e.g. on x86 and 1520 powerpc, libc++ will not be enabled by default, so libc++ should be 1521 built (with clang) and installed first. If both clang and libc++ are 1522 missing, build clang first, then use it to build libc++. 1523 1524 On 8.x and earlier installations, upgrade to 9.x first, and then follow 1525 the instructions for 9.x above. 1526 1527 Sparc64 and mips users are unaffected, as they still use gcc 4.2.1 by 1528 default, and do not build clang. 1529 1530 Many embedded systems are resource constrained, and will not be able to 1531 build clang in a reasonable time, or in some cases at all. In those 1532 cases, cross building bootable systems on amd64 is a workaround. 1533 1534 This new version of clang introduces a number of new warnings, of which 1535 the following are most likely to appear: 1536 1537 -Wabsolute-value 1538 1539 This warns in two cases, for both C and C++: 1540 * When the code is trying to take the absolute value of an unsigned 1541 quantity, which is effectively a no-op, and almost never what was 1542 intended. The code should be fixed, if at all possible. If you are 1543 sure that the unsigned quantity can be safely cast to signed, without 1544 loss of information or undefined behavior, you can add an explicit 1545 cast, or disable the warning. 1546 1547 * When the code is trying to take an absolute value, but the called 1548 abs() variant is for the wrong type, which can lead to truncation. 1549 If you want to disable the warning instead of fixing the code, please 1550 make sure that truncation will not occur, or it might lead to unwanted 1551 side-effects. 1552 1553 -Wtautological-undefined-compare and 1554 -Wundefined-bool-conversion 1555 1556 These warn when C++ code is trying to compare 'this' against NULL, while 1557 'this' should never be NULL in well-defined C++ code. However, there is 1558 some legacy (pre C++11) code out there, which actively abuses this 1559 feature, which was less strictly defined in previous C++ versions. 1560 1561 Squid and openjdk do this, for example. The warning can be turned off 1562 for C++98 and earlier, but compiling the code in C++11 mode might result 1563 in unexpected behavior; for example, the parts of the program that are 1564 unreachable could be optimized away. 1565 156620141222: 1567 The old NFS client and server (kernel options NFSCLIENT, NFSSERVER) 1568 kernel sources have been removed. The .h files remain, since some 1569 utilities include them. This will need to be fixed later. 1570 If "mount -t oldnfs ..." is attempted, it will fail. 1571 If the "-o" option on mountd(8), nfsd(8) or nfsstat(1) is used, 1572 the utilities will report errors. 1573 157420141121: 1575 The handling of LOCAL_LIB_DIRS has been altered to skip addition of 1576 directories to top level SUBDIR variable when their parent 1577 directory is included in LOCAL_DIRS. Users with build systems with 1578 such hierarchies and without SUBDIR entries in the parent 1579 directory Makefiles should add them or add the directories to 1580 LOCAL_DIRS. 1581 158220141109: 1583 faith(4) and faithd(8) have been removed from the base system. Faith 1584 has been obsolete for a very long time. 1585 158620141104: 1587 vt(4), the new console driver, is enabled by default. It brings 1588 support for Unicode and double-width characters, as well as 1589 support for UEFI and integration with the KMS kernel video 1590 drivers. 1591 1592 You may need to update your console settings in /etc/rc.conf, 1593 most probably the keymap. During boot, /etc/rc.d/syscons will 1594 indicate what you need to do. 1595 1596 vt(4) still has issues and lacks some features compared to 1597 syscons(4). See the wiki for up-to-date information: 1598 https://wiki.freebsd.org/Newcons 1599 1600 If you want to keep using syscons(4), you can do so by adding 1601 the following line to /boot/loader.conf: 1602 kern.vty=sc 1603 160420141102: 1605 pjdfstest has been integrated into kyua as an opt-in test suite. 1606 Please see share/doc/pjdfstest/README for more details on how to 1607 execute it. 1608 160920141009: 1610 gperf has been removed from the base system for architectures 1611 that use clang. Ports that require gperf will obtain it from the 1612 devel/gperf port. 1613 161420140923: 1615 pjdfstest has been moved from tools/regression/pjdfstest to 1616 contrib/pjdfstest . 1617 161820140922: 1619 At svn r271982, The default linux compat kernel ABI has been adjusted 1620 to 2.6.18 in support of the linux-c6 compat ports infrastructure 1621 update. If you wish to continue using the linux-f10 compat ports, 1622 add compat.linux.osrelease=2.6.16 to your local sysctl.conf. Users are 1623 encouraged to update their linux-compat packages to linux-c6 during 1624 their next update cycle. 1625 162620140729: 1627 The ofwfb driver, used to provide a graphics console on PowerPC when 1628 using vt(4), no longer allows mmap() of all physical memory. This 1629 will prevent Xorg on PowerPC with some ATI graphics cards from 1630 initializing properly unless x11-servers/xorg-server is updated to 1631 1.12.4_8 or newer. 1632 163320140723: 1634 The xdev targets have been converted to using TARGET and 1635 TARGET_ARCH instead of XDEV and XDEV_ARCH. 1636 163720140719: 1638 The default unbound configuration has been modified to address 1639 issues with reverse lookups on networks that use private 1640 address ranges. If you use the local_unbound service, run 1641 "service local_unbound setup" as root to regenerate your 1642 configuration, then "service local_unbound reload" to load the 1643 new configuration. 1644 164520140709: 1646 The GNU texinfo and GNU info pages are not built and installed 1647 anymore, WITH_INFO knob has been added to allow to built and install 1648 them again. 1649 UPDATE: see 20150102 entry on texinfo's removal 1650 165120140708: 1652 The GNU readline library is now an INTERNALLIB - that is, it is 1653 statically linked into consumers (GDB and variants) in the base 1654 system, and the shared library is no longer installed. The 1655 devel/readline port is available for third party software that 1656 requires readline. 1657 165820140702: 1659 The Itanium architecture (ia64) has been removed from the list of 1660 known architectures. This is the first step in the removal of the 1661 architecture. 1662 166320140701: 1664 Commit r268115 has added NFSv4.1 server support, merged from 1665 projects/nfsv4.1-server. Since this includes changes to the 1666 internal interfaces between the NFS related modules, a full 1667 build of the kernel and modules will be necessary. 1668 __FreeBSD_version has been bumped. 1669 167020140629: 1671 The WITHOUT_VT_SUPPORT kernel config knob has been renamed 1672 WITHOUT_VT. (The other _SUPPORT knobs have a consistent meaning 1673 which differs from the behaviour controlled by this knob.) 1674 167520140619: 1676 Maximal length of the serial number in CTL was increased from 16 to 1677 64 chars, that breaks ABI. All CTL-related tools, such as ctladm 1678 and ctld, need to be rebuilt to work with a new kernel. 1679 168020140606: 1681 The libatf-c and libatf-c++ major versions were downgraded to 0 and 1682 1 respectively to match the upstream numbers. They were out of 1683 sync because, when they were originally added to FreeBSD, the 1684 upstream versions were not respected. These libraries are private 1685 and not yet built by default, so renumbering them should be a 1686 non-issue. However, unclean source trees will yield broken test 1687 programs once the operator executes "make delete-old-libs" after a 1688 "make installworld". 1689 1690 Additionally, the atf-sh binary was made private by moving it into 1691 /usr/libexec/. Already-built shell test programs will keep the 1692 path to the old binary so they will break after "make delete-old" 1693 is run. 1694 1695 If you are using WITH_TESTS=yes (not the default), wipe the object 1696 tree and rebuild from scratch to prevent spurious test failures. 1697 This is only needed once: the misnumbered libraries and misplaced 1698 binaries have been added to OptionalObsoleteFiles.inc so they will 1699 be removed during a clean upgrade. 1700 170120140512: 1702 Clang and llvm have been upgraded to 3.4.1 release. 1703 170420140508: 1705 We bogusly installed src.opts.mk in /usr/share/mk. This file should 1706 be removed to avoid issues in the future (and has been added to 1707 ObsoleteFiles.inc). 1708 170920140505: 1710 /etc/src.conf now affects only builds of the FreeBSD src tree. In the 1711 past, it affected all builds that used the bsd.*.mk files. The old 1712 behavior was a bug, but people may have relied upon it. To get this 1713 behavior back, you can .include /etc/src.conf from /etc/make.conf 1714 (which is still global and isn't changed). This also changes the 1715 behavior of incremental builds inside the tree of individual 1716 directories. Set MAKESYSPATH to ".../share/mk" to do that. 1717 Although this has survived make universe and some upgrade scenarios, 1718 other upgrade scenarios may have broken. At least one form of 1719 temporary breakage was fixed with MAKESYSPATH settings for buildworld 1720 as well... In cases where MAKESYSPATH isn't working with this 1721 setting, you'll need to set it to the full path to your tree. 1722 1723 One side effect of all this cleaning up is that bsd.compiler.mk 1724 is no longer implicitly included by bsd.own.mk. If you wish to 1725 use COMPILER_TYPE, you must now explicitly include bsd.compiler.mk 1726 as well. 1727 172820140430: 1729 The lindev device has been removed since /dev/full has been made a 1730 standard device. __FreeBSD_version has been bumped. 1731 173220140424: 1733 The knob WITHOUT_VI was added to the base system, which controls 1734 building ex(1), vi(1), etc. Older releases of FreeBSD required ex(1) 1735 in order to reorder files share/termcap and didn't build ex(1) as a 1736 build tool, so building/installing with WITH_VI is highly advised for 1737 build hosts for older releases. 1738 1739 This issue has been fixed in stable/9 and stable/10 in r277022 and 1740 r276991, respectively. 1741 174220140418: 1743 The YES_HESIOD knob has been removed. It has been obsolete for 1744 a decade. Please move to using WITH_HESIOD instead or your builds 1745 will silently lack HESIOD. 1746 174720140405: 1748 The uart(4) driver has been changed with respect to its handling 1749 of the low-level console. Previously the uart(4) driver prevented 1750 any process from changing the baudrate or the CLOCAL and HUPCL 1751 control flags. By removing the restrictions, operators can make 1752 changes to the serial console port without having to reboot. 1753 However, when getty(8) is started on the serial device that is 1754 associated with the low-level console, a misconfigured terminal 1755 line in /etc/ttys will now have a real impact. 1756 Before upgrading the kernel, make sure that /etc/ttys has the 1757 serial console device configured as 3wire without baudrate to 1758 preserve the previous behaviour. E.g: 1759 ttyu0 "/usr/libexec/getty 3wire" vt100 on secure 1760 176120140306: 1762 Support for libwrap (TCP wrappers) in rpcbind was disabled by default 1763 to improve performance. To re-enable it, if needed, run rpcbind 1764 with command line option -W. 1765 176620140226: 1767 Switched back to the GPL dtc compiler due to updates in the upstream 1768 dts files not being supported by the BSDL dtc compiler. You will need 1769 to rebuild your kernel toolchain to pick up the new compiler. Core dumps 1770 may result while building dtb files during a kernel build if you fail 1771 to do so. Set WITHOUT_GPL_DTC if you require the BSDL compiler. 1772 177320140216: 1774 Clang and llvm have been upgraded to 3.4 release. 1775 177620140216: 1777 The nve(4) driver has been removed. Please use the nfe(4) driver 1778 for NVIDIA nForce MCP Ethernet adapters instead. 1779 178020140212: 1781 An ABI incompatibility crept into the libc++ 3.4 import in r261283. 1782 This could cause certain C++ applications using shared libraries built 1783 against the previous version of libc++ to crash. The incompatibility 1784 has now been fixed, but any C++ applications or shared libraries built 1785 between r261283 and r261801 should be recompiled. 1786 178720140204: 1788 OpenSSH will now ignore errors caused by kernel lacking of Capsicum 1789 capability mode support. Please note that enabling the feature in 1790 kernel is still highly recommended. 1791 179220140131: 1793 OpenSSH is now built with sandbox support, and will use sandbox as 1794 the default privilege separation method. This requires Capsicum 1795 capability mode support in kernel. 1796 179720140128: 1798 The libelf and libdwarf libraries have been updated to newer 1799 versions from upstream. Shared library version numbers for 1800 these two libraries were bumped. Any ports or binaries 1801 requiring these two libraries should be recompiled. 1802 __FreeBSD_version is bumped to 1100006. 1803 180420140110: 1805 If a Makefile in a tests/ directory was auto-generating a Kyuafile 1806 instead of providing an explicit one, this would prevent such 1807 Makefile from providing its own Kyuafile in the future during 1808 NO_CLEAN builds. This has been fixed in the Makefiles but manual 1809 intervention is needed to clean an objdir if you use NO_CLEAN: 1810 # find /usr/obj -name Kyuafile | xargs rm -f 1811 181220131213: 1813 The behavior of gss_pseudo_random() for the krb5 mechanism 1814 has changed, for applications requesting a longer random string 1815 than produced by the underlying enctype's pseudo-random() function. 1816 In particular, the random string produced from a session key of 1817 enctype aes256-cts-hmac-sha1-96 or aes256-cts-hmac-sha1-96 will 1818 be different at the 17th octet and later, after this change. 1819 The counter used in the PRF+ construction is now encoded as a 1820 big-endian integer in accordance with RFC 4402. 1821 __FreeBSD_version is bumped to 1100004. 1822 182320131108: 1824 The WITHOUT_ATF build knob has been removed and its functionality 1825 has been subsumed into the more generic WITHOUT_TESTS. If you were 1826 using the former to disable the build of the ATF libraries, you 1827 should change your settings to use the latter. 1828 182920131025: 1830 The default version of mtree is nmtree which is obtained from 1831 NetBSD. The output is generally the same, but may vary 1832 slightly. If you found you need identical output adding 1833 "-F freebsd9" to the command line should do the trick. For the 1834 time being, the old mtree is available as fmtree. 1835 183620131014: 1837 libbsdyml has been renamed to libyaml and moved to /usr/lib/private. 1838 This will break ports-mgmt/pkg. Rebuild the port, or upgrade to pkg 1839 1.1.4_8 and verify bsdyml not linked in, before running "make 1840 delete-old-libs": 1841 # make -C /usr/ports/ports-mgmt/pkg build deinstall install clean 1842 or 1843 # pkg install pkg; ldd /usr/local/sbin/pkg | grep bsdyml 1844 184520131010: 1846 The stable/10 branch has been created in subversion from head 1847 revision r256279. 1848 1849COMMON ITEMS: 1850 1851 General Notes 1852 ------------- 1853 Avoid using make -j when upgrading. While generally safe, there are 1854 sometimes problems using -j to upgrade. If your upgrade fails with 1855 -j, please try again without -j. From time to time in the past there 1856 have been problems using -j with buildworld and/or installworld. This 1857 is especially true when upgrading between "distant" versions (eg one 1858 that cross a major release boundary or several minor releases, or when 1859 several months have passed on the -current branch). 1860 1861 Sometimes, obscure build problems are the result of environment 1862 poisoning. This can happen because the make utility reads its 1863 environment when searching for values for global variables. To run 1864 your build attempts in an "environmental clean room", prefix all make 1865 commands with 'env -i '. See the env(1) manual page for more details. 1866 1867 When upgrading from one major version to another it is generally best to 1868 upgrade to the latest code in the currently installed branch first, then 1869 do an upgrade to the new branch. This is the best-tested upgrade path, 1870 and has the highest probability of being successful. Please try this 1871 approach if you encounter problems with a major version upgrade. Since 1872 the stable 4.x branch point, one has generally been able to upgrade from 1873 anywhere in the most recent stable branch to head / current (or even the 1874 last couple of stable branches). See the top of this file when there's 1875 an exception. 1876 1877 When upgrading a live system, having a root shell around before 1878 installing anything can help undo problems. Not having a root shell 1879 around can lead to problems if pam has changed too much from your 1880 starting point to allow continued authentication after the upgrade. 1881 1882 This file should be read as a log of events. When a later event changes 1883 information of a prior event, the prior event should not be deleted. 1884 Instead, a pointer to the entry with the new information should be 1885 placed in the old entry. Readers of this file should also sanity check 1886 older entries before relying on them blindly. Authors of new entries 1887 should write them with this in mind. 1888 1889 ZFS notes 1890 --------- 1891 When upgrading the boot ZFS pool to a new version, always follow 1892 these two steps: 1893 1894 1.) recompile and reinstall the ZFS boot loader and boot block 1895 (this is part of "make buildworld" and "make installworld") 1896 1897 2.) update the ZFS boot block on your boot drive 1898 1899 The following example updates the ZFS boot block on the first 1900 partition (freebsd-boot) of a GPT partitioned drive ada0: 1901 "gpart bootcode -p /boot/gptzfsboot -i 1 ada0" 1902 1903 Non-boot pools do not need these updates. 1904 1905 To build a kernel 1906 ----------------- 1907 If you are updating from a prior version of FreeBSD (even one just 1908 a few days old), you should follow this procedure. It is the most 1909 failsafe as it uses a /usr/obj tree with a fresh mini-buildworld, 1910 1911 make kernel-toolchain 1912 make -DALWAYS_CHECK_MAKE buildkernel KERNCONF=YOUR_KERNEL_HERE 1913 make -DALWAYS_CHECK_MAKE installkernel KERNCONF=YOUR_KERNEL_HERE 1914 1915 To test a kernel once 1916 --------------------- 1917 If you just want to boot a kernel once (because you are not sure 1918 if it works, or if you want to boot a known bad kernel to provide 1919 debugging information) run 1920 make installkernel KERNCONF=YOUR_KERNEL_HERE KODIR=/boot/testkernel 1921 nextboot -k testkernel 1922 1923 To rebuild everything and install it on the current system. 1924 ----------------------------------------------------------- 1925 # Note: sometimes if you are running current you gotta do more than 1926 # is listed here if you are upgrading from a really old current. 1927 1928 <make sure you have good level 0 dumps> 1929 make buildworld 1930 make buildkernel KERNCONF=YOUR_KERNEL_HERE 1931 make installkernel KERNCONF=YOUR_KERNEL_HERE 1932 [1] 1933 <reboot in single user> [3] 1934 mergemaster -Fp [5] 1935 make installworld 1936 mergemaster -Fi [4] 1937 make delete-old [6] 1938 <reboot> 1939 1940 To cross-install current onto a separate partition 1941 -------------------------------------------------- 1942 # In this approach we use a separate partition to hold 1943 # current's root, 'usr', and 'var' directories. A partition 1944 # holding "/", "/usr" and "/var" should be about 2GB in 1945 # size. 1946 1947 <make sure you have good level 0 dumps> 1948 <boot into -stable> 1949 make buildworld 1950 make buildkernel KERNCONF=YOUR_KERNEL_HERE 1951 <maybe newfs current's root partition> 1952 <mount current's root partition on directory ${CURRENT_ROOT}> 1953 make installworld DESTDIR=${CURRENT_ROOT} -DDB_FROM_SRC 1954 make distribution DESTDIR=${CURRENT_ROOT} # if newfs'd 1955 make installkernel KERNCONF=YOUR_KERNEL_HERE DESTDIR=${CURRENT_ROOT} 1956 cp /etc/fstab ${CURRENT_ROOT}/etc/fstab # if newfs'd 1957 <edit ${CURRENT_ROOT}/etc/fstab to mount "/" from the correct partition> 1958 <reboot into current> 1959 <do a "native" rebuild/install as described in the previous section> 1960 <maybe install compatibility libraries from ports/misc/compat*> 1961 <reboot> 1962 1963 1964 To upgrade in-place from stable to current 1965 ---------------------------------------------- 1966 <make sure you have good level 0 dumps> 1967 make buildworld [9] 1968 make buildkernel KERNCONF=YOUR_KERNEL_HERE [8] 1969 make installkernel KERNCONF=YOUR_KERNEL_HERE 1970 [1] 1971 <reboot in single user> [3] 1972 mergemaster -Fp [5] 1973 make installworld 1974 mergemaster -Fi [4] 1975 make delete-old [6] 1976 <reboot> 1977 1978 Make sure that you've read the UPDATING file to understand the 1979 tweaks to various things you need. At this point in the life 1980 cycle of current, things change often and you are on your own 1981 to cope. The defaults can also change, so please read ALL of 1982 the UPDATING entries. 1983 1984 Also, if you are tracking -current, you must be subscribed to 1985 freebsd-current@freebsd.org. Make sure that before you update 1986 your sources that you have read and understood all the recent 1987 messages there. If in doubt, please track -stable which has 1988 much fewer pitfalls. 1989 1990 [1] If you have third party modules, such as vmware, you 1991 should disable them at this point so they don't crash your 1992 system on reboot. 1993 1994 [3] From the bootblocks, boot -s, and then do 1995 fsck -p 1996 mount -u / 1997 mount -a 1998 sh /etc/rc.d/zfs start # mount zfs filesystem, if needed 1999 cd src # full path to source 2000 adjkerntz -i # if CMOS is wall time 2001 Also, when doing a major release upgrade, it is required that 2002 you boot into single user mode to do the installworld. 2003 2004 [4] Note: This step is non-optional. Failure to do this step 2005 can result in a significant reduction in the functionality of the 2006 system. Attempting to do it by hand is not recommended and those 2007 that pursue this avenue should read this file carefully, as well 2008 as the archives of freebsd-current and freebsd-hackers mailing lists 2009 for potential gotchas. The -U option is also useful to consider. 2010 See mergemaster(8) for more information. 2011 2012 [5] Usually this step is a no-op. However, from time to time 2013 you may need to do this if you get unknown user in the following 2014 step. It never hurts to do it all the time. You may need to 2015 install a new mergemaster (cd src/usr.sbin/mergemaster && make 2016 install) after the buildworld before this step if you last updated 2017 from current before 20130425 or from -stable before 20130430. 2018 2019 [6] This only deletes old files and directories. Old libraries 2020 can be deleted by "make delete-old-libs", but you have to make 2021 sure that no program is using those libraries anymore. 2022 2023 [8] The new kernel must be able to run existing binaries used by an 2024 installworld. When upgrading across major versions, the new kernel's 2025 configuration must include the correct COMPAT_FREEBSD<n> option for 2026 existing binaries (e.g. COMPAT_FREEBSD11 to run 11.x binaries). Failure 2027 to do so may leave you with a system that is hard to boot to recover. A 2028 GENERIC kernel will include suitable compatibility options to run 2029 binaries from older branches. Note that the ability to run binaries 2030 from unsupported branches is not guaranteed. 2031 2032 Make sure that you merge any new devices from GENERIC since the 2033 last time you updated your kernel config file. Options also 2034 change over time, so you may need to adjust your custom kernels 2035 for these as well. 2036 2037 [9] If CPUTYPE is defined in your /etc/make.conf, make sure to use the 2038 "?=" instead of the "=" assignment operator, so that buildworld can 2039 override the CPUTYPE if it needs to. 2040 2041 MAKEOBJDIRPREFIX must be defined in an environment variable, and 2042 not on the command line, or in /etc/make.conf. buildworld will 2043 warn if it is improperly defined. 2044FORMAT: 2045 2046This file contains a list, in reverse chronological order, of major 2047breakages in tracking -current. It is not guaranteed to be a complete 2048list of such breakages, and only contains entries since September 23, 2011. 2049If you need to see UPDATING entries from before that date, you will need 2050to fetch an UPDATING file from an older FreeBSD release. 2051 2052Copyright information: 2053 2054Copyright 1998-2009 M.
