1Updating Information for users of FreeBSD-CURRENT. 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://docs.freebsd.org/en/books/handbook/cutting-edge/#makeworld 10 11Items affecting the ports and packages system can be found in 12/usr/ports/UPDATING. Please read that file before updating system packages 13and/or ports. 14 15NOTE TO PEOPLE WHO THINK THAT FreeBSD 15.x IS SLOW: 16 FreeBSD 15.x has many debugging features turned on, in both the kernel 17 and userland. These features attempt to detect incorrect use of 18 system primitives, and encourage loud failure through extra sanity 19 checking and fail stop semantics. They also substantially impact 20 system performance. If you want to do performance measurement, 21 benchmarking, and optimization, you'll want to turn them off. This 22 includes various WITNESS- related kernel options, INVARIANTS, malloc 23 debugging flags in userland, and various verbose features in the 24 kernel. Many developers choose to disable these features on build 25 machines to maximize performance. (To completely disable malloc 26 debugging, define WITH_MALLOC_PRODUCTION in /etc/src.conf and rebuild 27 world, or to merely disable the most expensive debugging functionality 28 at runtime, run "ln -s 'abort:false,junk:false' /etc/malloc.conf".) 29 3020231010: 31 dialog(1) has been replaced in base by bsddialog(1), while most of the 32 time replacing a dialog(1) call by a bsddialog(1) call works out of the 33 box, bsddialog(1) is not considered as a drop-in replacement for 34 dialog(1). 35 36 If you do depend on dialog(1) functionality, please install cdialog 37 from ports: 38 39 pkg install cdialog 40 4120230927: 42 The EARLY_AP_STARTUP kernel option is mandatory on x86. The option 43 has been added to DEFAULTS, so it should automatically be included in 44 custom kernel configurations without any additional change. 45 4620230922: 47 A new loader tunable net.pf.default_to_drop allows pf(4)’s default 48 behaviour to be changed from pass to drop. Previously this required 49 recompiling the kernel with the option PF_DEFAULT_TO_DROP. 50 5120230914: 52 Enable splitting out pkgbase manpages into separate packages by 53 default. To disable this, set WITHOUT_MANSPLITPKG=yes in src.conf. 54 5520230911: 56 Move standard include files to the clibs-dev package and move clang 57 internal libraries and headers to clang and clang-dev. Upgrading systems 58 installed using pkgbase past this change involves extra steps to allow 59 for these file moves: 60 61 pkg upgrade -y FreeBSD-utilities 62 pkg upgrade -y FreeBSD-utilities-dev 63 pkg upgrade -y 64 6520230909: 66 Enable vnet sysctl variables to be loader tunable. SYSCTLs which 67 belongs to VNETs can be initialized during early boot or module 68 loading if they are marked with CTLFLAG_TUN and there are 69 corresponding kernel environment variables. 70 7120230901: 72 The WITH_INIT_ALL_PATTERN and WITH_INIT_ALL_ZERO build options have 73 been replaced by INIT_ALL=pattern and INIT_ALL=zero respectively. 74 7520230824: 76 FreeBSD 15.0-CURRENT. 77 7820230817: 79 Serial communication (in boot loaders, kernel, and userland) has 80 been changed to default to 115200 bps, in line with common industry 81 practice and typcial firmware serial console redirection 82 configuration. 83 84 Note that the early x86 BIOS bootloader (i.e., boot0sio) does not 85 support rates above 9600 bps and is not changed. boot0sio users may 86 set BOOT_COMCONSOLE_SPEED=9600 to use 9600 for all of the boot 87 components, or use the standard boot0 and have the boot2 stage start 88 with the serial port at 115200. 89 9020230807: 91 Following the general removal of MIPS support, the ath(4) AHB bus- 92 frontend has been removed, too, and building of the PCI support is 93 integrated with the ath(4) main module again. As a result, there's 94 no longer a need for if_ath_pci_load="YES" in /boot/loader.conf or 95 "device ath_pci" in the kernel configuration. 96 9720230803: 98 MAXCPU has been increased to 1024 in the amd64 GENERIC kernel config. 99 Out-of-tree kernel modules will need to be rebuilt. 100 10120230724: 102 CAM has been mechanically updated s/u_int(64|32|16|8)_t/uint\1_t/g 103 to move to the standard uintXX_t types from the old, traditional 104 BSD u_intXX_t types. This should be a NOP, but may cause problems 105 for out of tree changes. The SIMs were not updated since most of 106 the old u_intXX_t uses weren't due to CAM interfaces. 107 10820230629: 109 The heuristic for detecting old chromebooks with an EC bug that requires 110 atkbdc driver workarounds has changed. There should be no functional 111 change, but if your old chromebook's keyboard stops working, please 112 file a PR and assign it to imp. 113 11420230623: 115 OpenSSL has been updated to version 3.0, including changes throughout 116 the base system. It is important to rebuild third-party software 117 after upgrading. 118 11920230619: 120 To enable pf rdr rules for connections initiated from the host, pf 121 filter rules can be optionally enabled for packets delivered 122 locally. This can change the behavior of rules which match packets 123 delivered to lo0. To enable this feature: 124 125 sysctl net.pf.filter_local=1 126 service pf restart 127 128 When enabled, its best to ensure that packets delivered locally are not 129 filtered, e.g. by adding a 'skip on lo' rule. 130 13120230613: 132 Improvements to libtacplus(8) mean that tacplus.conf(5) now 133 follows POSIX shell syntax rules. This may cause TACACS+ 134 authentication to fail if the shared secret contains a single 135 quote, double quote, or backslash character which isn't 136 already properly quoted or escaped. 137 13820230612: 139 Belatedly switch the default nvme block device on x86 from nvd to nda. 140 nda created nvd compatibility links by default, so this should be a 141 nop. If this causes problems for your application, set hw.nvme.use_nvd=1 142 in your loader.conf or add `options NVME_USE_NVD=1` to your kernel 143 config. To disable the nvd compatibility aliases, add 144 kern.cam.nda.nvd_compat=0 to loader.conf. The default has been nda on 145 all non-x86 platforms for some time now. If you need to fall back, 146 please email imp@freebsd.org about why. 147 148 Encrypted swap partitions need to be changed from nvd to nda if you 149 migrate, or you need to use the above to switch back to nvd. 150 15120230422: 152 Remove portsnap(8). Users are encouraged to obtain the ports tree 153 using git instead. 154 15520230420: 156 Add jobs.mk to save typing. Enables -j${JOB_MAX} and logging 157 eg. 158 make buildworld-jobs 159 runs 160 make -j${JOB_MAX} buildworld > ../buildworld.log 2>&1 161 162 where JOB_MAX is derrived from ncpus in local.sys.mk if not set in env. 163 16420230316: 165 Video related devices for some arm devices have been renamed. 166 If you have a custom kernel config and want to use hdmi output on 167 IMX6 board you need to add "device dwc_hdmi" "device imx6_hdmi" and 168 "device imx6_ipu" to it. 169 If you have a custom kernel config and want to use hdmi output on 170 TI AM335X board you need to add "device tda19988" to it. 171 If you add "device hdmi" in it you need to remove it as it doesn't 172 exist anymore. 173 17420230221: 175 Introduce new kernel options KBD_DELAY1 and KBD_DELAY2. See atkbdc(4) 176 for details. 177 17820230206: 179 sshd now defaults to having X11Forwarding disabled, following upstream. 180 Administrators who wish to enable X11Forwarding should add 181 `X11Forwarding yes` to /etc/ssh/sshd_config. 182 18320230204: 184 Since commit 75d41cb6967 Huawei 3G/4G LTE Mobile Devices do not default 185 to ECM, but NCM mode and need u3g and ucom modules loaded. See cdce(4). 186 18720230130: 188 As of commit 7c40e2d5f685, the dependency on netlink(4) has been added 189 to the linux_common(4) module. Users relying on linux_common may need 190 to complile netlink(4) module if it is not present in their kernel. 191 19220230126: 193 The WITHOUT_CXX option has been removed. C++ components in the base 194 system are now built unconditionally. 195 19620230113: 197 LinuxKPI pci.h changes may require out-of-tree drivers to be recompiled. 198 Bump _FreeBSD_version to 1400078 to be able to detect this change. 199 20020221212: 201 llvm-objump is now always installed as objdump. Previously there was 202 no /usr/bin/objdump unless the WITH_LLVM_BINUTILS knob was used. 203 204 Some LLVM objdump options have a different output format compared to 205 GNU objdump; readelf is available for inspecting ELF files, and GNU 206 objdump is available from the devel/binutils port or package. 207 20820221205: 209 dma(8) has replaced sendmail(8) as the default mta. For people willing 210 to reenable sendmail(8): 211 212 $ cp /usr/share/examples/sendmail/mailer.conf /etc/mail/mailer.conf 213 214 and add sendmail_enable="YES" to rc.conf. 215 21620221204: 217 hw.bus.disable_failed_devices has changed from 'false' to 'true' by 218 default. Now if newbus succeeds in probing a device, but fails to attach 219 the device, we'll disable the device. In the past, we'd keep retrying 220 the device on each new driver loaded. To get that behavior now, one 221 needs to use devctl to re-enable the device, and reprobe it (or set 222 the sysctl/tunable hw.bus.disable_failed_devices=false). 223 224 NOTE: This was reverted 20221205 due to unexpected compatibility issues 225 22620221122: 227 pf no longer accepts 'scrub fragment crop' or 'scrub fragment drop-ovl'. 228 These configurations are no longer automatically reinterpreted as 229 'scrub fragment reassemble'. 230 23120221121: 232 The WITHOUT_CLANG_IS_CC option has been removed. When Clang is enabled 233 it is always installed as /usr/bin/cc (and c++, cpp). 234 23520221026: 236 Some programs have been moved into separate packages. It is recommended 237 for pkgbase users to do: 238 239 pkg install FreeBSD-dhclient FreeBSD-geom FreeBSD-resolvconf \ 240 FreeBSD-devd FreeBSD-devmatch 241 242 after upgrading to restore all the component that were previously 243 installed. 244 24520221002: 246 OPIE has been removed from the base system. If needed, it can 247 be installed from ports (security/opie) or packages (opie). 248 Otherwise, make sure that your PAM policies do not reference 249 pam_opie or pam_opieaccess. 250 25120220610: 252 LinuxKPI pm.h changes require an update to the latest drm-kmod version 253 before re-compiling to avoid errors. 254 25520211230: 256 The macros provided for the manipulation of CPU sets (e.g. CPU_AND) 257 have been modified to take 2 source arguments instead of only 1. 258 Externally maintained sources that use these macros will have to 259 be adapted. The FreeBSD version has been bumped to 1400046 to 260 reflect this change. 261 26220211214: 263 A number of the kernel include files are able to be included by 264 themselves. A test has been added to buildworld to enforce this. 265 26620211209: 267 Remove mips as a recognized target. This starts the decommissioning of 268 mips support in FreeBSD. mips related items will be removed wholesale in 269 the coming days and weeks. 270 271 This broke the NO_CLEAN build for some people. Either do a clean build 272 or touch 273 lib/clang/include/llvm/Config/Targets.def 274 lib/clang/include/llvm/Config/AsmParsers.def 275 lib/clang/include/llvm/Config/Disassemblers.def 276 lib/clang/include/llvm/Config/AsmPrinters.def 277 before the build to force everything to rebuild that needs to. 278 27920211202: 280 Unbound support for RFC8375: The special-use domain 'home.arpa' is 281 by default blocked. To unblock it use a local-zone nodefault 282 statement in unbound.conf: 283 local-zone: "home.arpa." nodefault 284 285 Or use another type of local-zone to override with your choice. 286 287 The reason for this is discussed in Section 6.1 of RFC8375: 288 Because 'home.arpa.' is not globally scoped and cannot be secured 289 using DNSSEC based on the root domain's trust anchor, there is no way 290 to tell, using a standard DNS query, in which homenet scope an answer 291 belongs. Consequently, users may experience surprising results with 292 such names when roaming to different homenets. 293 29420211110: 295 Commit b8d60729deef changed the TCP congestion control framework so 296 that any of the included congestion control modules could be 297 the single module built into the kernel. Previously newreno 298 was automatically built in through direct reference. As of 299 this commit you are required to declare at least one congestion 300 control module (e.g. 'options CC_NEWRENO') and to also declare a 301 default using the CC_DEFAULT option (e.g. options CC_DEFAULT="newreno\"). 302 The GENERIC configuration includes CC_NEWRENO and defines newreno 303 as the default. If no congestion control option is built into the 304 kernel and you are including networking, the kernel compile will 305 fail. Also if no default is declared the kernel compile will fail. 306 30720211118: 308 Mips has been removed from universe builds. It will be removed from the 309 tree shortly. 310 31120211106: 312 Commit f0c9847a6c47 changed the arguments for VOP_ALLOCATE. 313 The NFS modules must be rebuilt from sources and any out 314 of tree file systems that implement their own VOP_ALLOCATE 315 may need to be modified. 316 31720211022: 318 The synchronous PPP kernel driver sppp(4) has been removed. 319 The cp(4) and ce(4) drivers are now always compiled with netgraph(4) 320 support, formerly enabled by NETGRAPH_CRONYX option. 321 32220211020: 323 sh(1) is now the default shell for the root user. To force root to use 324 the csh shell, please run the following command as root: 325 326 # chsh -s csh 327 32820211004: 329 Ncurses distribution has been split between libtinfow and libncurses 330 with libncurses.so becoming a linker (ld) script to seamlessly link 331 to libtinfow as needed. Bump _FreeBSD_version to 1400035 to reflect 332 this change. 333 33420210923: 335 As of commit 8160a0f62be6, the dummynet module no longer depends on the 336 ipfw module. Dummynet can now be used by pf as well as ipfw. As such 337 users who relied on this dependency may need to include ipfw in the 338 list of modules to load on their systems. 339 34020210922: 341 As of commit 903873ce1560, the mixer(8) utility has got a slightly 342 new syntax. Please refer to the mixer(8) manual page for more 343 information. The old mixer utility can be installed from ports: 344 audio/freebsd-13-mixer 345 34620210911: 347 As of commit 55089ef4f8bb, the global variable nfs_maxcopyrange has 348 been deleted from the nfscommon.ko. As such, nfsd.ko must be built 349 from up to date sources to avoid an undefined reference when 350 being loaded. 351 35220210817: 353 As of commit 62ca9fc1ad56 OpenSSL no longer enables kernel TLS 354 by default. Users can enable kernel TLS via the "KTLS" SSL 355 option. This can be enabled globally by using a custom 356 OpenSSL config file via OPENSSL_CONF or via an 357 application-specific configuration option for applications 358 which permit setting SSL options via SSL_CONF_cmd(3). 359 36020210811: 361 Commit 3ad1e1c1ce20 changed the internal KAPI between the NFS 362 modules. Therefore, all need to be rebuilt from sources. 363 36420210730: 365 Commit b69019c14cd8 removes pf's DIOCGETSTATESNV ioctl. 366 As of be70c7a50d32 it is no longer used by userspace, but it does mean 367 users may not be able to enumerate pf states if they update the kernel 368 past b69019c14cd8 without first updating userspace past be70c7a50d32. 369 37020210729: 371 As of commit 01ad0c007964 if_bridge member interfaces can no longer 372 change their MTU. Changing the MTU of the bridge itself will change the 373 MTU on all member interfaces instead. 374 37520210716: 376 Commit ee29e6f31111 changed the internal KAPI between the nfscommon 377 and nfsd modules. Therefore, both need to be rebuilt from sources. 378 Bump __FreeBSD_version to 1400026 for this KAPI change. 379 38020210715: 381 The 20210707 awk update brought in a change in behavior. This has 382 been corrected as of d4d252c49976. Between these dates, if you 383 installed a new awk binary, you may not be able to build a new 384 kernel because the change in behavior affected the genoffset 385 script used to build the kernel. If you did update, the fix is 386 to update your sources past the above hash and do 387 % cd usr.bin/awk 388 % make clean all 389 % sudo -E make install 390 to enable building kernels again. 391 39220210708: 393 Commit 1e0a518d6548 changed the internal KAPI between the NFS 394 modules. They all need to be rebuilt from sources. I did not 395 bump __FreeBSD_version, since it was bumped recently. 396 39720210707: 398 awk has been updated to the latest one-true-awk version 20210215. 399 This contains a number of minor bug fixes. 400 40120210624: 402 The NFSv4 client now uses the highest minor version of NFSv4 403 supported by the NFSv4 server by default instead of minor version 0, 404 for NFSv4 mounts. 405 The "minorversion" mount option may be used to override this default. 406 40720210618: 408 Bump __FreeBSD_version to 1400024 for LinuxKPI changes. 409 Most notably netdev.h can change now as the (last) dependencies 410 (mlx4/ofed) are now using struct ifnet directly, but also for PCI 411 additions and others. 412 41320210618: 414 The directory "blacklisted" under /usr/share/certs/ has been 415 renamed to "untrusted". 416 41720210611: 418 svnlite has been removed from base. Should you need svn for any reason 419 please install the svn package or port. 420 42120210611: 422 Commit e1a907a25cfa changed the internal KAPI between the krpc 423 and nfsserver. As such, both modules must be rebuilt from 424 sources. Bump __FreeBSD_version to 1400022. 425 42620210610: 427 The an(4) driver has been removed from FreeBSD. 428 42920210608: 430 The vendor/openzfs branch was renamed to vendor/openzfs/legacy to 431 start tracking OpenZFS upstream more closely. Please see 432https://lists.freebsd.org/archives/freebsd-current/2021-June/000153.html 433 for details on how to correct any errors that might result. The 434 short version is that you need to remove the old branch locally: 435 git update-ref -d refs/remotes/freebsd/vendor/openzfs 436 (assuming your upstream origin is named 'freebsd'). 437 43820210525: 439 Commits 17accc08ae15 and de102f870501 add new files to LinuxKPI 440 which break drm-kmod. In addition various other additions where 441 committed. Bump __FreeBSD_version to 1400015 to be able to 442 detect this. 443 44420210513: 445 Commit ca179c4d74f2 changed the package in which the OpenSSL 446 libraries and utilities are packaged. 447 It is recommended for pkgbase user to do: 448 pkg install -f FreeBSD-openssl 449 before pkg upgrade otherwise some dependencies might not be met 450 and pkg will stop working as libssl will not be present anymore 451 on the system. 452 45320210426: 454 Commit 875977314881 changed the internal KAPI between 455 the nfsd and nfscommon modules. As such these modules 456 need to be rebuilt from sources. 457 Without this patch in your NFSv4.1/4.2 server, enabling 458 delegations by setting vfs.nfsd.issue_delegations non-zero 459 is not recommended. 460 46120210411: 462 Commit 7763814fc9c2 changed the internal KAPI between 463 the krpc and NFS. As such, the krpc, nfscommon and 464 nfscl modules must all be rebuilt from sources. 465 Without this patch, NFSv4.1/4.2 mounts should not 466 be done with the nfscbd(8) daemon running, to avoid 467 needing a working back channel for server->client RPCs. 468 46920210330: 470 Commit 01ae8969a9ee fixed the NFSv4.1/4.2 server so that it 471 handles binding of the back channel as required by RFC5661. 472 Until this patch is in your server, avoid use of the "nconnects" 473 mount option for Linux NFSv4.1/4.2 mounts. 474 47520210225: 476 For 64-bit architectures the base system is now built with Position 477 Independent Executable (PIE) support enabled by default. It may be 478 disabled using the WITHOUT_PIE knob. A clean build is required. 479 48020210128: 481 Various LinuxKPI functionality was added which conflicts with DRM. 482 Please update your drm-kmod port to after the __FreeBSD_version 1400003 483 update. 484 48520210108: 486 PC Card attachments for all devices have been removed. In the case of 487 wi and cmx, the entire drivers were removed because they were only 488 PC Card devices. FreeBSD_version 1300134 should be used for this 489 since it was bumped so recently. 490 49120210107: 492 Transport-independent parts of HID support have been split off the USB 493 code in to separate subsystem. Kernel configs which include one of 494 ums, ukbd, uhid, atp, wsp, wmt, uaudio, ugold or ucycom drivers should 495 be updated with adding of "device hid" line. 496 49720210105: 498 ncurses installation has been modified to only keep the widechar 499 enabled version. Incremental build is broken for that change, so it 500 requires a clean build. 501 50220201223: 503 The FreeBSD project has migrated from Subversion to Git. Temporary 504 instructions can be found at 505 https://github.com/bsdimp/freebsd-git-docs/blob/main/src-cvt.md 506 and other documents in that repo. 507 50820201216: 509 The services database has been updated to cover more of the basic 510 services expected in a modern system. The database is big enough 511 that it will cause issues in mergemaster in Releases previous to 512 12.2 and 11.3, or in very old current systems from before r358154. 513 51420201215: 515 Obsolete in-tree GDB 6.1.1 has been removed. GDB (including kgdb) 516 may be installed from ports or packages. 517 51820201124: 519 ping6 has been merged into ping. It can now be called as "ping -6". 520 See ping(8) for details. 521 52220201108: 523 Default value of net.add_addr_allfibs has been changed to 0. 524 If you have multi-fib configuration and rely on existence of all 525 interface routes in every fib, you need to set the above sysctl to 1. 526 52720201030: 528 The internal pre-processor in the calendar(1) program has been 529 extended to support more C pre-processor commands (e.g. #ifdef, #else, 530 and #undef) and to detect unbalanced conditional statements. 531 Error messages have been extended to include the filename and line 532 number if processing stops to help fixing malformed data files. 533 53420201026: 535 All the data files for the calendar(1) program, except calendar.freebsd, 536 have been moved to the deskutils/calendar-data port, much like the 537 jewish calendar entries were moved to deskutils/hebcal years ago. After 538 make delete-old-files, you need to install it to retain full 539 functionality. calendar(1) will issue a reminder for files it can't 540 find. 541 54220200923: 543 LINT files are no longer generated. We now include the relevant NOTES 544 files. Note: This may cause conflicts with updating in some cases. 545 find sys -name LINT\* -delete 546 is suggested across this commit to remove the generated LINT files. 547 548 If you have tried to update with generated files there, the svn 549 command you want to un-auger the tree is 550 cd sys/amd64/conf 551 svn revert -R . 552 and then do the above find from the top level. Substitute 'amd64' 553 above with where the error message indicates a conflict. 554 55520200824: 556 OpenZFS support has been integrated. Do not upgrade root pools until 557 the loader is updated to support zstd. Furthermore, we caution against 558 'zpool upgrade' for the next few weeks. The change should be transparent 559 unless you want to use new features. 560 561 Not all "NO_CLEAN" build scenarios work across these changes. Many 562 scenarios have been tested and fixed, but rebuilding kernels without 563 rebuilding world may fail. 564 565 The ZFS cache file has moved from /boot to /etc to match the OpenZFS 566 upstream default. A fallback to /boot has been added for mountroot. 567 568 Pool auto import behavior at boot has been moved from the kernel module 569 to an explicit "zpool import -a" in one of the rc scripts enabled by 570 zfs_enable=YES. This means your non-root zpools won't auto import until 571 you upgrade your /etc/rc.d files. 572 57320200824: 574 The resume code now notifies devd with the 'kernel' system 575 rather than the old 'kern' subsystem to be consistent with 576 other use. The old notification will be created as well, but 577 will be removed prior to FreeBSD 14.0. 578 57920200821: 580 r362275 changed the internal API between the kernel RPC and the 581 NFS modules. As such, all the modules must be recompiled from 582 sources. 583 58420200817: 585 r364330 modified the internal API used between the NFS modules. 586 As such, all the NFS modules must be re-compiled from sources. 587 58820200816: 589 Clang, llvm, lld, lldb, compiler-rt, libc++, libunwind and openmp have 590 been upgraded to 11.0.0. Please see the 20141231 entry below for 591 information about prerequisites and upgrading, if you are not already 592 using clang 3.5.0 or higher. 593 59420200810: 595 r364092 modified the internal ABI used between the kernel NFS 596 modules. As such, all of these modules need to be rebuilt 597 from sources, so a version bump was done. 598 59920200807: 600 Makefile.inc has been updated to work around the issue documented in 601 20200729. It was a case where the optimization of using symbolic links 602 to point to binaries created a situation where we'd run new binaries 603 with old libraries starting midway through the installworld process. 604 60520200729: 606 r363679 has redefined some undefined behavior in regcomp(3); notably, 607 extraneous escapes of most ordinary characters will no longer be 608 accepted. An exp-run has identified all of the problems with this in 609 ports, but other non-ports software may need extra escapes removed to 610 continue to function. 611 612 Because of this change, installworld may encounter the following error 613 from rtld: Undefined symbol "regcomp@FBSD_1.6" -- It is imperative that 614 you do not halt installworld. Instead, let it run to completion (whether 615 successful or not) and run installworld once more. 616 61720200627: 618 A new implementation of bc and dc has been imported in r362681. This 619 implementation corrects non-conformant behavior of the previous bc 620 and adds GNU bc compatible options. It offers a number of extensions, 621 is much faster on large values, and has support for message catalogs 622 (a number of languages are already supported, contributions of further 623 languages welcome). The option WITHOUT_GH_BC can be used to build the 624 world with the previous versions of bc and dc. 625 62620200625: 627 r362639 changed the internal API used between the NFS kernel modules. 628 As such, they all need to be rebuilt from sources. 629 63020200613: 631 r362158 changed the arguments for VFS_CHECKEXP(). As such, any 632 out of tree file systems need to be modified and rebuilt. 633 Also, any file systems that are modules must be rebuilt. 634 63520200604: 636 read(2) of a directory fd is now rejected by default. root may 637 re-enable it for system root only on non-ZFS filesystems with the 638 security.bsd.allow_read_dir sysctl(8) MIB if 639 security.bsd.suser_enabled=1. 640 641 It may be advised to setup aliases for grep to default to `-d skip` if 642 commonly non-recursively grepping a list that includes directories and 643 the potential for the resulting stderr output is not tolerable. Example 644 aliases are now installed, commented out, in /root/.cshrc and 645 /root/.shrc. 646 64720200523: 648 Clang, llvm, lld, lldb, compiler-rt, libc++, libunwind and openmp have 649 been upgraded to 10.0.1. Please see the 20141231 entry below for 650 information about prerequisites and upgrading, if you are not already 651 using clang 3.5.0 or higher. 652 65320200512: 654 Support for obsolete compilers has been removed from the build system. 655 Clang 6 and GCC 6.4 are the minimum supported versions. 656 65720200424: 658 closefrom(2) has been moved under COMPAT12, and replaced in libc with a 659 stub that calls close_range(2). If using a custom kernel configuration, 660 you may want to ensure that the COMPAT_FREEBSD12 option is included, as 661 a slightly older -CURRENT userland and older FreeBSD userlands may not 662 be functional without closefrom(2). 663 66420200414: 665 Upstream DTS from Linux 5.6 was merged and they now have the SID 666 and THS (Secure ID controller and THermal Sensor) node present. 667 The DTB overlays have now been removed from the tree for the H3/H5 and 668 A64 SoCs and the aw_sid and aw_thermal driver have been updated to 669 deal with upstream DTS. If you are using those overlays you need to 670 remove them from loader.conf and update the DTBs on the FAT partition. 671 67220200310: 673 Clang, llvm, lld, lldb, compiler-rt, libc++, libunwind and openmp have 674 been upgraded to 10.0.0. Please see the 20141231 entry below for 675 information about prerequisites and upgrading, if you are not already 676 using clang 3.5.0 or higher. 677 67820200309: 679 The amd(8) automount daemon has been removed from the source tree. 680 As of FreeBSD 10.1 autofs(5) is the preferred tool for automounting. 681 amd is still available in the sysutils/am-utils port. 682 68320200301: 684 Removed brooktree driver (bktr.4) from the tree. 685 68620200229: 687 The WITH_GPL_DTC option has been removed. The BSD-licenced device tree 688 compiler in usr.bin/dtc is used on all architectures which use dtc, and 689 the GPL dtc is available (if needed) from the sysutils/dtc port. 690 69120200229: 692 The WITHOUT_LLVM_LIBUNWIND option has been removed. LLVM's libunwind 693 is used by all supported CPU architectures. 694 69520200229: 696 GCC 4.2.1 has been removed from the tree. The WITH_GCC, 697 WITH_GCC_BOOTSTRAP, and WITH_GNUCXX options are no longer available. 698 Users who wish to build FreeBSD with GCC must use the external toolchain 699 ports or packages. 700 70120200220: 702 ncurses has been updated to a newer version (6.2-20200215). Given the ABI 703 has changed, users will have to rebuild all the ports that are linked to 704 ncurses. 705 70620200217: 707 The size of struct vnet and the magic cookie have changed. 708 Users need to recompile libkvm and all modules using VIMAGE 709 together with their new kernel. 710 71120200212: 712 Defining the long deprecated NO_CTF, NO_DEBUG_FILES, NO_INSTALLLIB, 713 NO_MAN, NO_PROFILE, and NO_WARNS variables is now an error. Update 714 your Makefiles and scripts to define MK_<var>=no instead as required. 715 716 One exception to this is that program or library Makefiles should 717 define MAN to empty rather than setting MK_MAN=no. 718 71920200108: 720 Clang/LLVM is now the default compiler and LLD the default 721 linker for riscv64. 722 72320200107: 724 make universe no longer uses GCC 4.2.1 on any architectures. 725 Architectures not supported by in-tree Clang/LLVM require an 726 external toolchain package. 727 72820200104: 729 GCC 4.2.1 is now not built by default, as part of the GCC 4.2.1 730 retirement plan. Specifically, the GCC, GCC_BOOTSTRAP, and GNUCXX 731 options default to off for all supported CPU architectures. As a 732 short-term transition aid they may be enabled via WITH_* options. 733 GCC 4.2.1 is expected to be removed from the tree on 2020-03-31. 734 73520200102: 736 Support for armv5 has been disconnected and is being removed. The 737 machine combination MACHINE=arm MACHINE_ARCH=arm is no longer valid. 738 You must now use a MACHINE_ARCH of armv6 or armv7. The default 739 MACHINE_ARCH for MACHINE=arm is now armv7. 740 74120191226: 742 Clang/LLVM is now the default compiler for all powerpc architectures. 743 LLD is now the default linker for powerpc64. The change for powerpc64 744 also includes a change to the ELFv2 ABI, incompatible with the existing 745 ABI. 746 74720191226: 748 Kernel-loadable random(4) modules are no longer unloadable. 749 75020191222: 751 Clang, llvm, lld, lldb, compiler-rt, libc++, libunwind and openmp have 752 been upgraded to 9.0.1. Please see the 20141231 entry below for 753 information about prerequisites and upgrading, if you are not already 754 using clang 3.5.0 or higher. 755 75620191212: 757 r355677 has modified the internal interface used between the 758 NFS modules in the kernel. As such, they must all be upgraded 759 simultaneously. I will do a version bump for this. 760 76120191205: 762 The root certificates of the Mozilla CA Certificate Store have been 763 imported into the base system and can be managed with the certctl(8) 764 utility. If you have installed the security/ca_root_nss port or package 765 with the ETCSYMLINK option (the default), be advised that there may be 766 differences between those included in the port and those included in 767 base due to differences in nss branch used as well as general update 768 frequency. Note also that certctl(8) cannot manage certs in the 769 format used by the security/ca_root_nss port. 770 77120191120: 772 The amd(8) automount daemon has been disabled by default, and will be 773 removed in the future. As of FreeBSD 10.1 the autofs(5) is available 774 for automounting. 775 77620191107: 777 The nctgpio and wbwd drivers have been moved to the superio bus. 778 If you have one of these drivers in a kernel configuration, then 779 you should add device superio to it. If you use one of these drivers 780 as a module and you compile a custom set of modules, then you should 781 add superio to the set. 782 78320191021: 784 KPIs for network drivers to access interface addresses have changed. 785 Users need to recompile NIC driver modules together with kernel. 786 78720191021: 788 The net.link.tap.user_open sysctl no longer prevents user opening of 789 already created /dev/tapNN devices. Access is still controlled by 790 node permissions, just like tun devices. The net.link.tap.user_open 791 sysctl is now used only to allow users to perform devfs cloning of 792 tap devices, and the subsequent open may not succeed if the user is not 793 in the appropriate group. This sysctl may be deprecated/removed 794 completely in the future. 795 79620191009: 797 mips, powerpc, and sparc64 are no longer built as part of 798 universe / tinderbox unless MAKE_OBSOLETE_GCC is defined. If 799 not defined, mips, powerpc, and sparc64 builds will look for 800 the xtoolchain binaries and if installed use them for universe 801 builds. As llvm 9.0 becomes vetted for these architectures, they 802 will be removed from the list. 803 80420191009: 805 Clang, llvm, lld, lldb, compiler-rt, libc++, libunwind and openmp have 806 been upgraded to 9.0.0. Please see the 20141231 entry below for 807 information about prerequisites and upgrading, if you are not already 808 using clang 3.5.0 or higher. 809 81020191003: 811 The hpt27xx, hptmv, hptnr, and hptrr drivers have been removed from 812 GENERIC. They are available as modules and can be loaded by adding 813 to /boot/loader.conf hpt27xx_load="YES", hptmv_load="YES", 814 hptnr_load="YES", or hptrr_load="YES", respectively. 815 81620190913: 817 ntpd no longer by default locks its pages in memory, allowing them 818 to be paged out by the kernel. Use rlimit memlock to restore 819 historic BSD behaviour. For example, add "rlimit memlock 32" 820 to ntp.conf to lock up to 32 MB of ntpd address space in memory. 821 82220190823: 823 Several of ping6's options have been renamed for better consistency 824 with ping. If you use any of -ARWXaghmrtwx, you must update your 825 scripts. See ping6(8) for details. 826 82720190727: 828 The vfs.fusefs.sync_unmount and vfs.fusefs.init_backgrounded sysctls 829 and the "-o sync_unmount" and "-o init_backgrounded" mount options have 830 been removed from mount_fusefs(8). You can safely remove them from 831 your scripts, because they had no effect. 832 833 The vfs.fusefs.fix_broken_io, vfs.fusefs.sync_resize, 834 vfs.fusefs.refresh_size, vfs.fusefs.mmap_enable, 835 vfs.fusefs.reclaim_revoked, and vfs.fusefs.data_cache_invalidate 836 sysctls have been removed. If you felt the need to set any of them to 837 a non-default value, please tell asomers@FreeBSD.org why. 838 83920190713: 840 Default permissions on the /var/account/acct file (and copies of it 841 rotated by periodic daily scripts) are changed from 0644 to 0640 842 because the file contains sensitive information that should not be 843 world-readable. If the /var/account directory must be created by 844 rc.d/accounting, the mode used is now 0750. Admins who use the 845 accounting feature are encouraged to change the mode of an existing 846 /var/account directory to 0750 or 0700. 847 84820190620: 849 Entropy collection and the /dev/random device are no longer optional 850 components. The "device random" option has been removed. 851 Implementations of distilling algorithms can still be made loadable 852 with "options RANDOM_LOADABLE" (e.g., random_fortuna.ko). 853 85420190612: 855 Clang, llvm, lld, lldb, compiler-rt, libc++, libunwind and openmp have 856 been upgraded to 8.0.1. Please see the 20141231 entry below for 857 information about prerequisites and upgrading, if you are not already 858 using clang 3.5.0 or higher. 859 86020190608: 861 A fix was applied to i386 kernel modules to avoid panics with 862 dpcpu or vnet. Users need to recompile i386 kernel modules 863 having pcpu or vnet sections or they will refuse to load. 864 86520190513: 866 User-wired pages now have their own counter, 867 vm.stats.vm.v_user_wire_count. The vm.max_wired sysctl was renamed 868 to vm.max_user_wired and changed from an unsigned int to an unsigned 869 long. bhyve VMs wired with the -S are now subject to the user 870 wiring limit; the vm.max_user_wired sysctl may need to be tuned to 871 avoid running into the limit. 872 87320190507: 874 The IPSEC option has been removed from GENERIC. Users requiring 875 ipsec(4) must now load the ipsec(4) kernel module. 876 87720190507: 878 The tap(4) driver has been folded into tun(4), and the module has been 879 renamed to tuntap. You should update any kld_list="if_tap" or 880 kld_list="if_tun" entries in /etc/rc.conf, if_tap_load="YES" or 881 if_tun_load="YES" entries in /boot/loader.conf to load the if_tuntap 882 module instead, and "device tap" or "device tun" entries in kernel 883 config files to select the tuntap device instead. 884 88520190418: 886 The following knobs have been added related to tradeoffs between 887 safe use of the random device and availability in the absence of 888 entropy: 889 890 kern.random.initial_seeding.bypass_before_seeding: tunable; set 891 non-zero to bypass the random device prior to seeding, or zero to 892 block random requests until the random device is initially seeded. 893 For now, set to 1 (unsafe) by default to restore pre-r346250 boot 894 availability properties. 895 896 kern.random.initial_seeding.read_random_bypassed_before_seeding: 897 read-only diagnostic sysctl that is set when bypass is enabled and 898 read_random(9) is bypassed, to enable programmatic handling of this 899 initial condition, if desired. 900 901 kern.random.initial_seeding.arc4random_bypassed_before_seeding: 902 Similar to the above, but for arc4random(9) initial seeding. 903 904 kern.random.initial_seeding.disable_bypass_warnings: tunable; set 905 non-zero to disable warnings in dmesg when the same conditions are 906 met as for the diagnostic sysctls above. Defaults to zero, i.e., 907 produce warnings in dmesg when the conditions are met. 908 90920190416: 910 The loadable random module KPI has changed; the random_infra_init() 911 routine now requires a 3rd function pointer for a bool (*)(void) 912 method that returns true if the random device is seeded (and 913 therefore unblocked). 914 91520190404: 916 r345895 reverts r320698. This implies that an nfsuserd(8) daemon 917 built from head sources between r320757 (July 6, 2017) and 918 r338192 (Aug. 22, 2018) will not work unless the "-use-udpsock" 919 is added to the command line. 920 nfsuserd daemons built from head sources that are post-r338192 are 921 not affected and should continue to work. 922 92320190320: 924 The fuse(4) module has been renamed to fusefs(4) for consistency with 925 other filesystems. You should update any kld_load="fuse" entries in 926 /etc/rc.conf, fuse_load="YES" entries in /boot/loader.conf, and 927 "options FUSE" entries in kernel config files. 928 92920190304: 930 Clang, llvm, lld, lldb, compiler-rt and libc++ have been upgraded to 931 8.0.0. Please see the 20141231 entry below for information about 932 prerequisites and upgrading, if you are not already using clang 3.5.0 933 or higher. 934 93520190226: 936 geom_uzip(4) depends on the new module xz. If geom_uzip is statically 937 compiled into your custom kernel, add 'device xz' statement to the 938 kernel config. 939 94020190219: 941 drm and drm2 have been removed from the tree. Please see 942 https://wiki.freebsd.org/Graphics for the latest information on 943 migrating to the drm ports. 944 94520190131: 946 Iflib is no longer unconditionally compiled into the kernel. Drivers 947 using iflib and statically compiled into the kernel, now require 948 the 'device iflib' config option. For the same drivers loaded as 949 modules on kernels not having 'device iflib', the iflib.ko module 950 is loaded automatically. 951 95220190125: 953 The IEEE80211_AMPDU_AGE and AH_SUPPORT_AR5416 kernel configuration 954 options no longer exist since r343219 and r343427 respectively; 955 nothing uses them, so they should be just removed from custom 956 kernel config files. 957 95820181230: 959 r342635 changes the way efibootmgr(8) works by requiring users to add 960 the -b (bootnum) parameter for commands where the bootnum was previously 961 specified with each option. For example 'efibootmgr -B 0001' is now 962 'efibootmgr -B -b 0001'. 963 96420181220: 965 r342286 modifies the NFSv4 server so that it obeys vfs.nfsd.nfs_privport 966 in the same as it is applied to NFSv2 and 3. This implies that NFSv4 967 servers that have vfs.nfsd.nfs_privport set will only allow mounts 968 from clients using a reserved port. Since both the FreeBSD and Linux 969 NFSv4 clients use reserved ports by default, this should not affect 970 most NFSv4 mounts. 971 97220181219: 973 The XLP config has been removed. We can't support 64-bit atomics in this 974 kernel because it is running in 32-bit mode. XLP users must transition 975 to running a 64-bit kernel (XLP64 or XLPN32). 976 977 The mips GXEMUL support has been removed from FreeBSD. MALTA* + qemu is 978 the preferred emulator today and we don't need two different ones. 979 980 The old sibyte / swarm / Broadcom BCM1250 support has been 981 removed from the mips port. 982 98320181211: 984 Clang, llvm, lld, lldb, compiler-rt and libc++ have been upgraded to 985 7.0.1. Please see the 20141231 entry below for information about 986 prerequisites and upgrading, if you are not already using clang 3.5.0 987 or higher. 988 98920181211: 990 Remove the timed and netdate programs from the base tree. Setting 991 the time with these daemons has been obsolete for over a decade. 992 99320181126: 994 On amd64, arm64 and armv7 (architectures that install LLVM's ld.lld 995 linker as /usr/bin/ld) GNU ld is no longer installed as ld.bfd, as 996 it produces broken binaries when ifuncs are in use. Users needing 997 GNU ld should install the binutils port or package. 998 99920181123: 1000 The BSD crtbegin and crtend code has been enabled by default. It has 1001 had extensive testing on amd64, arm64, and i386. It can be disabled 1002 by building a world with -DWITHOUT_BSD_CRTBEGIN. 1003 100420181115: 1005 The set of CTM commands (ctm, ctm_smail, ctm_rmail, ctm_dequeue) 1006 has been converted to a port (misc/ctm) and will be removed from 1007 FreeBSD-13. It is available as a package (ctm) for all supported 1008 FreeBSD versions. 1009 101020181110: 1011 The default newsyslog.conf(5) file has been changed to only include 1012 files in /etc/newsyslog.conf.d/ and /usr/local/etc/newsyslog.conf.d/ if 1013 the filenames end in '.conf' and do not begin with a '.'. 1014 1015 You should check the configuration files in these two directories match 1016 this naming convention. You can verify which configuration files are 1017 being included using the command: 1018 $ newsyslog -Nrv 1019 102020181015: 1021 Ports for the DRM modules have been simplified. Now, amd64 users should 1022 just install the drm-kmod port. All others should install 1023 drm-legacy-kmod. 1024 1025 Graphics hardware that's newer than about 2010 usually works with 1026 drm-kmod. For hardware older than 2013, however, some users will need 1027 to use drm-legacy-kmod if drm-kmod doesn't work for them. Hardware older 1028 than 2008 usually only works in drm-legacy-kmod. The graphics team can 1029 only commit to hardware made since 2013 due to the complexity of the 1030 market and difficulty to test all the older cards effectively. If you 1031 have hardware supported by drm-kmod, you are strongly encouraged to use 1032 that as you will get better support. 1033 1034 Other than KPI chasing, drm-legacy-kmod will not be updated. As outlined 1035 elsewhere, the drm and drm2 modules will be eliminated from the src base 1036 soon (with a limited exception for arm). Please update to the package 1037 asap and report any issues to x11@freebsd.org. 1038 1039 Generally, anybody using the drm*-kmod packages should add 1040 WITHOUT_DRM_MODULE=t and WITHOUT_DRM2_MODULE=t to avoid nasty 1041 cross-threading surprises, especially with automatic driver 1042 loading from X11 startup. These will become the defaults in 13-current 1043 shortly. 1044 104520181012: 1046 The ixlv(4) driver has been renamed to iavf(4). As a consequence, 1047 custom kernel and module loading configuration files must be updated 1048 accordingly. Moreover, interfaces previous presented as ixlvN to the 1049 system are now exposed as iavfN and network configuration files must 1050 be adjusted as necessary. 1051 105220181009: 1053 OpenSSL has been updated to version 1.1.1. This update included 1054 additional various API changes throughout the base system. It is 1055 important to rebuild third-party software after upgrading. The value 1056 of __FreeBSD_version has been bumped accordingly. 1057 105820181006: 1059 The legacy DRM modules and drivers have now been added to the loader's 1060 module blacklist, in favor of loading them with kld_list in rc.conf(5). 1061 The module blacklist may be overridden with the loader.conf(5) 1062 'module_blacklist' variable, but loading them via rc.conf(5) is strongly 1063 encouraged. 1064 106520181002: 1066 The cam(4) based nda(4) driver will be used over nvd(4) by default on 1067 powerpc64. You may set 'options NVME_USE_NVD=1' in your kernel conf or 1068 loader tunable 'hw.nvme.use_nvd=1' if you wish to use the existing 1069 driver. Make sure to edit /boot/etc/kboot.conf and fstab to use the 1070 nda device name. 1071 107220180913: 1073 Reproducible build mode is now on by default, in preparation for 1074 FreeBSD 12.0. This eliminates build metadata such as the user, 1075 host, and time from the kernel (and uname), unless the working tree 1076 corresponds to a modified checkout from a version control system. 1077 The previous behavior can be obtained by setting the /etc/src.conf 1078 knob WITHOUT_REPRODUCIBLE_BUILD. 1079 108020180826: 1081 The Yarrow CSPRNG has been removed from the kernel as it has not been 1082 supported by its designers since at least 2003. Fortuna has been the 1083 default since FreeBSD-11. 1084 108520180822: 1086 devctl freeze/thaw have gone into the tree, the rc scripts have been 1087 updated to use them and devmatch has been changed. You should update 1088 kernel, userland and rc scripts all at the same time. 1089 109020180818: 1091 The default interpreter has been switched from 4th to Lua. 1092 LOADER_DEFAULT_INTERP, documented in build(7), will override the default 1093 interpreter. If you have custom FORTH code you will need to set 1094 LOADER_DEFAULT_INTERP=4th (valid values are 4th, lua or simp) in 1095 src.conf for the build. This will create default hard links between 1096 loader and loader_4th instead of loader and loader_lua, the new default. 1097 If you are using UEFI it will create the proper hard link to loader.efi. 1098 1099 bhyve uses userboot.so. It remains 4th-only until some issues are solved 1100 regarding coexisting with multiple versions of FreeBSD are resolved. 1101 110220180815: 1103 ls(1) now respects the COLORTERM environment variable used in other 1104 systems and software to indicate that a colored terminal is both 1105 supported and desired. If ls(1) is suddenly emitting colors, they may 1106 be disabled again by either removing the unwanted COLORTERM from your 1107 environment, or using `ls --color=never`. The ls(1) specific CLICOLOR 1108 may not be observed in a future release. 1109 111020180808: 1111 The default pager for most commands has been changed to "less". To 1112 restore the old behavior, set PAGER="more" and MANPAGER="more -s" in 1113 your environment. 1114 111520180731: 1116 The jedec_ts(4) driver has been removed. A superset of its functionality 1117 is available in the jedec_dimm(4) driver, and the manpage for that 1118 driver includes migration instructions. If you have "device jedec_ts" 1119 in your kernel configuration file, it must be removed. 1120 112120180730: 1122 amd64/GENERIC now has EFI runtime services, EFIRT, enabled by default. 1123 This should have no effect if the kernel is booted via BIOS/legacy boot. 1124 EFIRT may be disabled via a loader tunable, efi.rt.disabled, if a system 1125 has a buggy firmware that prevents a successful boot due to use of 1126 runtime services. 1127 112820180727: 1129 Atmel AT91RM9200 and AT91SAM9, Cavium CNS 11xx and XScale 1130 support has been removed from the tree. These ports were 1131 obsolete and/or known to be broken for many years. 1132 113320180723: 1134 loader.efi has been augmented to participate more fully in the 1135 UEFI boot manager protocol. loader.efi will now look at the 1136 BootXXXX environment variable to determine if a specific kernel 1137 or root partition was specified. XXXX is derived from BootCurrent. 1138 efibootmgr(8) manages these standard UEFI variables. 1139 114020180720: 1141 zfsloader's functionality has now been folded into loader. 1142 zfsloader is no longer necessary once you've updated your 1143 boot blocks. For a transition period, we will install a 1144 hardlink for zfsloader to loader to allow a smooth transition 1145 until the boot blocks can be updated (hard link because old 1146 zfs boot blocks don't understand symlinks). 1147 114820180719: 1149 ARM64 now have efifb support, if you want to have serial console 1150 on your arm64 board when an screen is connected and the bootloader 1151 setup a frame buffer for us to use, just add : 1152 boot_serial=YES 1153 boot_multicons=YES 1154 in /boot/loader.conf 1155 For Raspberry Pi 3 (RPI) users, this is needed even if you don't have 1156 an screen connected as the firmware will setup a frame buffer are that 1157 u-boot will expose as an EFI frame buffer. 1158 115920180719: 1160 New uid:gid added, ntpd:ntpd (123:123). Be sure to run mergemaster 1161 or take steps to update /etc/passwd before doing installworld on 1162 existing systems. Do not skip the "mergemaster -Fp" step before 1163 installworld, as described in the update procedures near the bottom 1164 of this document. Also, rc.d/ntpd now starts ntpd(8) as user ntpd 1165 if the new mac_ntpd(4) policy is available, unless ntpd_flags or 1166 the ntp config file contain options that change file/dir locations. 1167 When such options (e.g., "statsdir" or "crypto") are used, ntpd can 1168 still be run as non-root by setting ntpd_user=ntpd in rc.conf, after 1169 taking steps to ensure that all required files/dirs are accessible 1170 by the ntpd user. 1171 117220180717: 1173 Big endian arm support has been removed. 1174 117520180711: 1176 The static environment setup in kernel configs is no longer mutually 1177 exclusive with the loader(8) environment by default. In order to 1178 restore the previous default behavior of disabling the loader(8) 1179 environment if a static environment is present, you must specify 1180 loader_env.disabled=1 in the static environment. 1181 118220180705: 1183 The ABI of syscalls used by management tools like sockstat and 1184 netstat has been broken to allow 32-bit binaries to work on 1185 64-bit kernels without modification. These programs will need 1186 to match the kernel in order to function. External programs may 1187 require minor modifications to accommodate a change of type in 1188 structures from pointers to 64-bit virtual addresses. 1189 119020180702: 1191 On i386 and amd64 atomics are now inlined. Out of tree modules using 1192 atomics will need to be rebuilt. 1193 119420180701: 1195 The '%I' format in the kern.corefile sysctl limits the number of 1196 core files that a process can generate to the number stored in the 1197 debug.ncores sysctl. The '%I' format is replaced by the single digit 1198 index. Previously, if all indexes were taken the kernel would overwrite 1199 only a core file with the highest index in a filename. 1200 Currently the system will create a new core file if there is a free 1201 index or if all slots are taken it will overwrite the oldest one. 1202 120320180630: 1204 Clang, llvm, lld, lldb, compiler-rt and libc++ have been upgraded to 1205 6.0.1. Please see the 20141231 entry below for information about 1206 prerequisites and upgrading, if you are not already using clang 3.5.0 1207 or higher. 1208 120920180628: 1210 r335753 introduced a new quoting method. However, etc/devd/devmatch.conf 1211 needed to be changed to work with it. This change was made with r335763 1212 and requires a mergemaster / etcupdate / etc to update the installed 1213 file. 1214 121520180612: 1216 r334930 changed the interface between the NFS modules, so they all 1217 need to be rebuilt. r335018 did a __FreeBSD_version bump for this. 1218 121920180530: 1220 As of r334391 lld is the default amd64 system linker; it is installed 1221 as /usr/bin/ld. Kernel build workarounds (see 20180510 entry) are no 1222 longer necessary. 1223 122420180530: 1225 The kernel / userland interface for devinfo changed, so you'll 1226 need a new kernel and userland as a pair for it to work (rebuilding 1227 lib/libdevinfo is all that's required). devinfo and devmatch will 1228 not work, but everything else will when there's a mismatch. 1229 123020180523: 1231 The on-disk format for hwpmc callchain records has changed to include 1232 threadid corresponding to a given record. This changes the field offsets 1233 and thus requires that libpmcstat be rebuilt before using a kernel 1234 later than r334108. 1235 123620180517: 1237 The vxge(4) driver has been removed. This driver was introduced into 1238 HEAD one week before the Exar left the Ethernet market and is not 1239 known to be used. If you have device vxge in your kernel config file 1240 it must be removed. 1241 124220180510: 1243 The amd64 kernel now requires a ld that supports ifunc to produce a 1244 working kernel, either lld or a newer binutils. lld is built by default 1245 on amd64, and the 'buildkernel' target uses it automatically. However, 1246 it is not the default linker, so building the kernel the traditional 1247 way requires LD=ld.lld on the command line (or LD=/usr/local/bin/ld for 1248 binutils port/package). lld will soon be default, and this requirement 1249 will go away. 1250 1251 NOTE: As of r334391 lld is the default system linker on amd64, and no 1252 workaround is necessary. 1253 125420180508: 1255 The nxge(4) driver has been removed. This driver was for PCI-X 10g 1256 cards made by s2io/Neterion. The company was acquired by Exar and 1257 no longer sells or supports Ethernet products. If you have device 1258 nxge in your kernel config file it must be removed. 1259 126020180504: 1261 The tz database (tzdb) has been updated to 2018e. This version more 1262 correctly models time stamps in time zones with negative DST such as 1263 Europe/Dublin (from 1971 on), Europe/Prague (1946/7), and 1264 Africa/Windhoek (1994/2017). This does not affect the UT offsets, only 1265 time zone abbreviations and the tm_isdst flag. 1266 126720180502: 1268 The ixgb(4) driver has been removed. This driver was for an early and 1269 uncommon legacy PCI 10GbE for a single ASIC, Intel 82597EX. Intel 1270 quickly shifted to the long lived ixgbe family. If you have device 1271 ixgb in your kernel config file it must be removed. 1272 127320180501: 1274 The lmc(4) driver has been removed. This was a WAN interface 1275 card that was already reportedly rare in 2003, and had an ambiguous 1276 license. If you have device lmc in your kernel config file it must 1277 be removed. 1278 127920180413: 1280 Support for Arcnet networks has been removed. If you have device 1281 arcnet or device cm in your kernel config file they must be 1282 removed. 1283 128420180411: 1285 Support for FDDI networks has been removed. If you have device 1286 fddi or device fpa in your kernel config file they must be 1287 removed. 1288 128920180406: 1290 In addition to supporting RFC 3164 formatted messages, the 1291 syslogd(8) service is now capable of parsing RFC 5424 formatted 1292 log messages. The main benefit of using RFC 5424 is that clients 1293 may now send log messages with timestamps containing year numbers, 1294 microseconds and time zone offsets. 1295 1296 Similarly, the syslog(3) C library function has been altered to 1297 send RFC 5424 formatted messages to the local system logging 1298 daemon. On systems using syslogd(8), this change should have no 1299 negative impact, as long as syslogd(8) and the C library are 1300 updated at the same time. On systems using a different system 1301 logging daemon, it may be necessary to make configuration 1302 adjustments, depending on the software used. 1303 1304 When using syslog-ng, add the 'syslog-protocol' flag to local 1305 input sources to enable parsing of RFC 5424 formatted messages: 1306 1307 source src { 1308 unix-dgram("/var/run/log" flags(syslog-protocol)); 1309 } 1310 1311 When using rsyslog, disable the 'SysSock.UseSpecialParser' option 1312 of the 'imuxsock' module to let messages be processed by the 1313 regular RFC 3164/5424 parsing pipeline: 1314 1315 module(load="imuxsock" SysSock.UseSpecialParser="off") 1316 1317 Do note that these changes only affect communication between local 1318 applications and syslogd(8). The format that syslogd(8) uses to 1319 store messages on disk or forward messages to other systems 1320 remains unchanged. syslogd(8) still uses RFC 3164 for these 1321 purposes. Options to customize this behaviour will be added in the 1322 future. Utilities that process log files stored in /var/log are 1323 thus expected to continue to function as before. 1324 1325 __FreeBSD_version has been incremented to 1200061 to denote this 1326 change. 1327 132820180328: 1329 Support for token ring networks has been removed. If you 1330 have "device token" in your kernel config you should remove 1331 it. No device drivers supported token ring. 1332 133320180323: 1334 makefs was modified to be able to tag ISO9660 El Torito boot catalog 1335 entries as EFI instead of overloading the i386 tag as done previously. 1336 The amd64 mkisoimages.sh script used to build amd64 ISO images for 1337 release was updated to use this. This may mean that makefs must be 1338 updated before "make cdrom" can be run in the release directory. This 1339 should be as simple as: 1340 1341 $ cd $SRCDIR/usr.sbin/makefs 1342 $ make depend all install 1343 134420180212: 1345 FreeBSD boot loader enhanced with Lua scripting. It's purely opt-in for 1346 now by building WITH_LOADER_LUA and WITHOUT_FORTH in /etc/src.conf. 1347 Co-existence for the transition period will come shortly. Booting is a 1348 complex environment and test coverage for Lua-enabled loaders has been 1349 thin, so it would be prudent to assume it might not work and make 1350 provisions for backup boot methods. 1351 135220180211: 1353 devmatch functionality has been turned on in devd. It will automatically 1354 load drivers for unattached devices. This may cause unexpected drivers 1355 to be loaded. Please report any problems to current@ and 1356 imp@freebsd.org. 1357 135820180114: 1359 Clang, llvm, lld, lldb, compiler-rt and libc++ have been upgraded to 1360 6.0.0. Please see the 20141231 entry below for information about 1361 prerequisites and upgrading, if you are not already using clang 3.5.0 1362 or higher. 1363 136420180110: 1365 LLVM's lld linker is now used as the FreeBSD/amd64 bootstrap linker. 1366 This means it is used to link the kernel and userland libraries and 1367 executables, but is not yet installed as /usr/bin/ld by default. 1368 1369 To revert to ld.bfd as the bootstrap linker, in /etc/src.conf set 1370 WITHOUT_LLD_BOOTSTRAP=yes 1371 137220180110: 1373 On i386, pmtimer has been removed. Its functionality has been folded 1374 into apm. It was a no-op on ACPI in current for a while now (but was 1375 still needed on i386 in FreeBSD 11 and earlier). Users may need to 1376 remove it from kernel config files. 1377 137820180104: 1379 The use of RSS hash from the network card aka flowid has been 1380 disabled by default for lagg(4) as it's currently incompatible with 1381 the lacp and loadbalance protocols. 1382 1383 This can be re-enabled by setting the following in loader.conf: 1384 net.link.lagg.default_use_flowid="1" 1385 138620180102: 1387 The SW_WATCHDOG option is no longer necessary to enable the 1388 hardclock-based software watchdog if no hardware watchdog is 1389 configured. As before, SW_WATCHDOG will cause the software 1390 watchdog to be enabled even if a hardware watchdog is configured. 1391 139220171215: 1393 r326887 fixes the issue described in the 20171214 UPDATING entry. 1394 r326888 flips the switch back to building GELI support always. 1395 139620171214: 1397 r362593 broke ZFS + GELI support for reasons unknown. However, 1398 it also broke ZFS support generally, so GELI has been turned off 1399 by default as the lesser evil in r326857. If you boot off ZFS and/or 1400 GELI, it might not be a good time to update. 1401 140220171125: 1403 PowerPC users must update loader(8) by rebuilding world before 1404 installing a new kernel, as the protocol connecting them has 1405 changed. Without the update, loader metadata will not be passed 1406 successfully to the kernel and users will have to enter their 1407 root partition at the kernel mountroot prompt to continue booting. 1408 Newer versions of loader can boot old kernels without issue. 1409 141020171110: 1411 The LOADER_FIREWIRE_SUPPORT build variable has been renamed to 1412 WITH/OUT_LOADER_FIREWIRE. LOADER_{NO_,}GELI_SUPPORT has been renamed 1413 to WITH/OUT_LOADER_GELI. 1414 141520171106: 1416 The naive and non-compliant support of posix_fallocate(2) in ZFS 1417 has been removed as of r325320. The system call now returns EINVAL 1418 when used on a ZFS file. Although the new behavior complies with the 1419 standard, some consumers are not prepared to cope with it. 1420 One known victim is lld prior to r325420. 1421 142220171102: 1423 Building in a FreeBSD src checkout will automatically create object 1424 directories now rather than store files in the current directory if 1425 'make obj' was not ran. Calling 'make obj' is no longer necessary. 1426 This feature can be disabled by setting WITHOUT_AUTO_OBJ=yes in 1427 /etc/src-env.conf (not /etc/src.conf), or passing the option in the 1428 environment. 1429 143020171101: 1431 The default MAKEOBJDIR has changed from /usr/obj/<srcdir> for native 1432 builds, and /usr/obj/<arch>/<srcdir> for cross-builds, to a unified 1433 /usr/obj/<srcdir>/<arch>. This behavior can be changed to the old 1434 format by setting WITHOUT_UNIFIED_OBJDIR=yes in /etc/src-env.conf, 1435 the environment, or with -DWITHOUT_UNIFIED_OBJDIR when building. 1436 The UNIFIED_OBJDIR option is a transitional feature that will be 1437 removed for 12.0 release; please migrate to the new format for any 1438 tools by looking up the OBJDIR used by 'make -V .OBJDIR' means rather 1439 than hardcoding paths. 1440 144120171028: 1442 The native-xtools target no longer installs the files by default to the 1443 OBJDIR. Use the native-xtools-install target with a DESTDIR to install 1444 to ${DESTDIR}/${NXTP} where NXTP defaults to /nxb-bin. 1445 144620171021: 1447 As part of the boot loader infrastructure cleanup, LOADER_*_SUPPORT 1448 options are changing from controlling the build if defined / undefined 1449 to controlling the build with explicit 'yes' or 'no' values. They will 1450 shift to WITH/WITHOUT options to match other options in the system. 1451 145220171010: 1453 libstand has turned into a private library for sys/boot use only. 1454 It is no longer supported as a public interface outside of sys/boot. 1455 145620171005: 1457 The arm port has split armv6 into armv6 and armv7. armv7 is now 1458 a valid TARGET_ARCH/MACHINE_ARCH setting. If you have an armv7 system 1459 and are running a kernel from before r324363, you will need to add 1460 MACHINE_ARCH=armv7 to 'make buildworld' to do a native build. 1461 146220171003: 1463 When building multiple kernels using KERNCONF, non-existent KERNCONF 1464 files will produce an error and buildkernel will fail. Previously 1465 missing KERNCONF files silently failed giving no indication as to 1466 why, only to subsequently discover during installkernel that the 1467 desired kernel was never built in the first place. 1468 146920170912: 1470 The default serial number format for CTL LUNs has changed. This will 1471 affect users who use /dev/diskid/* device nodes, or whose FibreChannel 1472 or iSCSI clients care about their LUNs' serial numbers. Users who 1473 require serial number stability should hardcode serial numbers in 1474 /etc/ctl.conf . 1475 147620170912: 1477 For 32-bit arm compiled for hard-float support, soft-floating point 1478 binaries now always get their shared libraries from 1479 LD_SOFT_LIBRARY_PATH (in the past, this was only used if 1480 /usr/libsoft also existed). Only users with a hard-float ld.so, but 1481 soft-float everything else should be affected. 1482 148320170826: 1484 The geli password typed at boot is now hidden. To restore the previous 1485 behavior, see geli(8) for configuration options. 1486 148720170825: 1488 Move PMTUD blackhole counters to TCPSTATS and remove them from bare 1489 sysctl values. Minor nit, but requires a rebuild of both world/kernel 1490 to complete. 1491 149220170814: 1493 "make check" behavior (made in ^/head@r295380) has been changed to 1494 execute from a limited sandbox, as opposed to executing from 1495 ${TESTSDIR}. 1496 1497 Behavioral changes: 1498 - The "beforecheck" and "aftercheck" targets are now specified. 1499 - ${CHECKDIR} (added in commit noted above) has been removed. 1500 - Legacy behavior can be enabled by setting 1501 WITHOUT_MAKE_CHECK_USE_SANDBOX in src.conf(5) or the environment. 1502 1503 If the limited sandbox mode is enabled, "make check" will execute 1504 "make distribution", then install, execute the tests, and clean up the 1505 sandbox if successful. 1506 1507 The "make distribution" and "make install" targets are typically run as 1508 root to set appropriate permissions and ownership at installation time. 1509 The end-user should set "WITH_INSTALL_AS_USER" in src.conf(5) or the 1510 environment if executing "make check" with limited sandbox mode using 1511 an unprivileged user. 1512 151320170808: 1514 Since the switch to GPT disk labels, fsck for UFS/FFS has been 1515 unable to automatically find alternate superblocks. As of r322297, 1516 the information needed to find alternate superblocks has been 1517 moved to the end of the area reserved for the boot block. 1518 Filesystems created with a newfs of this vintage or later 1519 will create the recovery information. If you have a filesystem 1520 created prior to this change and wish to have a recovery block 1521 created for your filesystem, you can do so by running fsck in 1522 foreground mode (i.e., do not use the -p or -y options). As it 1523 starts, fsck will ask ``SAVE DATA TO FIND ALTERNATE SUPERBLOCKS'' 1524 to which you should answer yes. 1525 152620170728: 1527 As of r321665, an NFSv4 server configuration that services 1528 Kerberos mounts or clients that do not support the uid/gid in 1529 owner/owner_group string capability, must explicitly enable 1530 the nfsuserd daemon by adding nfsuserd_enable="YES" to the 1531 machine's /etc/rc.conf file. 1532 153320170722: 1534 Clang, llvm, lldb, compiler-rt and libc++ have been upgraded to 5.0.0. 1535 Please see the 20141231 entry below for information about prerequisites 1536 and upgrading, if you are not already using clang 3.5.0 or higher. 1537 153820170701: 1539 WITHOUT_RCMDS is now the default. Set WITH_RCMDS if you need the 1540 r-commands (rlogin, rsh, etc.) to be built with the base system. 1541 154220170625: 1543 The FreeBSD/powerpc platform now uses a 64-bit type for time_t. This is 1544 a very major ABI incompatible change, so users of FreeBSD/powerpc must 1545 be careful when performing source upgrades. It is best to run 1546 'make installworld' from an alternate root system, either a live 1547 CD/memory stick, or a temporary root partition. Additionally, all ports 1548 must be recompiled. powerpc64 is largely unaffected, except in the case 1549 of 32-bit compatibility. All 32-bit binaries will be affected. 1550 155120170623: 1552 Forward compatibility for the "ino64" project have been committed. This 1553 will allow most new binaries to run on older kernels in a limited 1554 fashion. This prevents many of the common foot-shooting actions in the 1555 upgrade as well as the limited ability to roll back the kernel across 1556 the ino64 upgrade. Complicated use cases may not work properly, though 1557 enough simpler ones work to allow recovery in most situations. 1558 155920170620: 1560 Switch back to the BSDL dtc (Device Tree Compiler). Set WITH_GPL_DTC 1561 if you require the GPL compiler. 1562 156320170618: 1564 The internal ABI used for communication between the NFS kernel modules 1565 was changed by r320085, so __FreeBSD_version was bumped to 1566 ensure all the NFS related modules are updated together. 1567 156820170617: 1569 The ABI of struct event was changed by extending the data 1570 member to 64bit and adding ext fields. For upgrade, same 1571 precautions as for the entry 20170523 "ino64" must be 1572 followed. 1573 157420170531: 1575 The GNU roff toolchain has been removed from base. To render manpages 1576 which are not supported by mandoc(1), man(1) can fallback on GNU roff 1577 from ports (and recommends to install it). 1578 To render roff(7) documents, consider using GNU roff from ports or the 1579 heirloom doctools roff toolchain from ports via pkg install groff or 1580 via pkg install heirloom-doctools. 1581 158220170524: 1583 The ath(4) and ath_hal(4) modules now build piecemeal to allow for 1584 smaller runtime footprint builds. This is useful for embedded systems 1585 which only require one chipset support. 1586 1587 If you load it as a module, make sure this is in /boot/loader.conf: 1588 1589 if_ath_load="YES" 1590 1591 This will load the HAL, all chip/RF backends and if_ath_pci. 1592 If you have if_ath_pci in /boot/loader.conf, ensure it is after 1593 if_ath or it will not load any HAL chipset support. 1594 1595 If you want to selectively load things (eg on cheaper ARM/MIPS 1596 platforms where RAM is at a premium) you should: 1597 1598 * load ath_hal 1599 * load the chip modules in question 1600 * load ath_rate, ath_dfs 1601 * load ath_main 1602 * load if_ath_pci and/or if_ath_ahb depending upon your particular 1603 bus bind type - this is where probe/attach is done. 1604 1605 For further comments/feedback, poke adrian@ . 1606 160720170523: 1608 The "ino64" 64-bit inode project has been committed, which extends 1609 a number of types to 64 bits. Upgrading in place requires care and 1610 adherence to the documented upgrade procedure. 1611 1612 If using a custom kernel configuration ensure that the 1613 COMPAT_FREEBSD11 option is included (as during the upgrade the 1614 system will be running the ino64 kernel with the existing world). 1615 1616 For the safest in-place upgrade begin by removing previous build 1617 artifacts via "rm -rf /usr/obj/*". Then, carefully follow the full 1618 procedure documented below under the heading "To rebuild everything and 1619 install it on the current system." Specifically, a reboot is required 1620 after installing the new kernel before installing world. While an 1621 installworld normally works by accident from multiuser after rebooting 1622 the proper kernel, there are many cases where this will fail across this 1623 upgrade and installworld from single user is required. 1624 162520170424: 1626 The NATM framework including the en(4), fatm(4), hatm(4), and 1627 patm(4) devices has been removed. Consumers should plan a 1628 migration before the end-of-life date for FreeBSD 11. 1629 163020170420: 1631 GNU diff has been replaced by a BSD licensed diff. Some features of GNU 1632 diff has not been implemented, if those are needed a newer version of 1633 GNU diff is available via the diffutils package under the gdiff name. 1634 163520170413: 1636 As of r316810 for ipfilter, keep frags is no longer assumed when 1637 keep state is specified in a rule. r316810 aligns ipfilter with 1638 documentation in man pages separating keep frags from keep state. 1639 This allows keep state to be specified without forcing keep frags 1640 and allows keep frags to be specified independently of keep state. 1641 To maintain previous behaviour, also specify keep frags with 1642 keep state (as documented in ipf.conf.5). 1643 164420170407: 1645 arm64 builds now use the base system LLD 4.0.0 linker by default, 1646 instead of requiring that the aarch64-binutils port or package be 1647 installed. To continue using aarch64-binutils, set 1648 CROSS_BINUTILS_PREFIX=/usr/local/aarch64-freebsd/bin . 1649 165020170405: 1651 The UDP optimization in entry 20160818 that added the sysctl 1652 net.inet.udp.require_l2_bcast has been reverted. L2 broadcast 1653 packets will no longer be treated as L3 broadcast packets. 1654 165520170331: 1656 Binds and sends to the loopback addresses, IPv6 and IPv4, will now 1657 use any explicitly assigned loopback address available in the jail 1658 instead of using the first assigned address of the jail. 1659 166020170329: 1661 The ctl.ko module no longer implements the iSCSI target frontend: 1662 cfiscsi.ko does instead. 1663 1664 If building cfiscsi.ko as a kernel module, the module can be loaded 1665 via one of the following methods: 1666 - `cfiscsi_load="YES"` in loader.conf(5). 1667 - Add `cfiscsi` to `$kld_list` in rc.conf(5). 1668 - ctladm(8)/ctld(8), when compiled with iSCSI support 1669 (`WITH_ISCSI=yes` in src.conf(5)) 1670 1671 Please see cfiscsi(4) for more details. 1672 167320170316: 1674 The mmcsd.ko module now additionally depends on geom_flashmap.ko. 1675 Also, mmc.ko and mmcsd.ko need to be a matching pair built from the 1676 same source (previously, the dependency of mmcsd.ko on mmc.ko was 1677 missing, but mmcsd.ko now will refuse to load if it is incompatible 1678 with mmc.ko). 1679 168020170315: 1681 The syntax of ipfw(8) named states was changed to avoid ambiguity. 1682 If you have used named states in the firewall rules, you need to modify 1683 them after installworld and before rebooting. Now named states must 1684 be prefixed with colon. 1685 168620170311: 1687 The old drm (sys/dev/drm/) drivers for i915 and radeon have been 1688 removed as the userland we provide cannot use them. The KMS version 1689 (sys/dev/drm2) supports the same hardware. 1690 169120170302: 1692 Clang, llvm, lldb, compiler-rt and libc++ have been upgraded to 4.0.0. 1693 Please see the 20141231 entry below for information about prerequisites 1694 and upgrading, if you are not already using clang 3.5.0 or higher. 1695 169620170221: 1697 The code that provides support for ZFS .zfs/ directory functionality 1698 has been reimplemented. It's not possible now to create a snapshot 1699 by mkdir under .zfs/snapshot/. That should be the only user visible 1700 change. 1701 170220170216: 1703 EISA bus support has been removed. The WITH_EISA option is no longer 1704 valid. 1705 170620170215: 1707 MCA bus support has been removed. 1708 170920170127: 1710 The WITH_LLD_AS_LD / WITHOUT_LLD_AS_LD build knobs have been renamed 1711 WITH_LLD_IS_LD / WITHOUT_LLD_IS_LD, for consistency with CLANG_IS_CC. 1712 171320170112: 1714 The EM_MULTIQUEUE kernel configuration option is deprecated now that 1715 the em(4) driver conforms to iflib specifications. 1716 171720170109: 1718 The igb(4), em(4) and lem(4) ethernet drivers are now implemented via 1719 IFLIB. If you have a custom kernel configuration that excludes em(4) 1720 but you use igb(4), you need to re-add em(4) to your custom 1721 configuration. 1722 172320161217: 1724 Clang, llvm, lldb, compiler-rt and libc++ have been upgraded to 3.9.1. 1725 Please see the 20141231 entry below for information about prerequisites 1726 and upgrading, if you are not already using clang 3.5.0 or higher. 1727 172820161124: 1729 Clang, llvm, lldb, compiler-rt and libc++ have been upgraded to 3.9.0. 1730 Please see the 20141231 entry below for information about prerequisites 1731 and upgrading, if you are not already using clang 3.5.0 or higher. 1732 173320161119: 1734 The layout of the pmap structure has changed for powerpc to put the pmap 1735 statistics at the front for all CPU variations. libkvm(3) and all tools 1736 that link against it need to be recompiled. 1737 173820161030: 1739 isl(4) and cyapa(4) drivers now require a new driver, 1740 chromebook_platform(4), to work properly on Chromebook-class hardware. 1741 On other types of hardware the drivers may need to be configured using 1742 device hints. Please see the corresponding manual pages for details. 1743 174420161017: 1745 The urtwn(4) driver was merged into rtwn(4) and now consists of 1746 rtwn(4) main module + rtwn_usb(4) and rtwn_pci(4) bus-specific 1747 parts. 1748 Also, firmware for RTL8188CE was renamed due to possible name 1749 conflict (rtwnrtl8192cU(B) -> rtwnrtl8192cE(B)) 1750 175120161015: 1752 GNU rcs has been removed from base. It is available as packages: 1753 - rcs: Latest GPLv3 GNU rcs version. 1754 - rcs57: Copy of the latest version of GNU rcs (GPLv2) before it was 1755 removed from base. 1756 175720161008: 1758 Use of the cc_cdg, cc_chd, cc_hd, or cc_vegas congestion control 1759 modules now requires that the kernel configuration contain the 1760 TCP_HHOOK option. (This option is included in the GENERIC kernel.) 1761 176220161003: 1763 The WITHOUT_ELFCOPY_AS_OBJCOPY src.conf(5) knob has been retired. 1764 ELF Tool Chain's elfcopy is always installed as /usr/bin/objcopy. 1765 176620160924: 1767 Relocatable object files with the extension of .So have been renamed 1768 to use an extension of .pico instead. The purpose of this change is 1769 to avoid a name clash with shared libraries on case-insensitive file 1770 systems. On those file systems, foo.So is the same file as foo.so. 1771 177220160918: 1773 GNU rcs has been turned off by default. It can (temporarily) be built 1774 again by adding WITH_RCS knob in src.conf. 1775 Otherwise, GNU rcs is available from packages: 1776 - rcs: Latest GPLv3 GNU rcs version. 1777 - rcs57: Copy of the latest version of GNU rcs (GPLv2) from base. 1778 177920160918: 1780 The backup_uses_rcs functionality has been removed from rc.subr. 1781 178220160908: 1783 The queue(3) debugging macro, QUEUE_MACRO_DEBUG, has been split into 1784 two separate components, QUEUE_MACRO_DEBUG_TRACE and 1785 QUEUE_MACRO_DEBUG_TRASH. Define both for the original 1786 QUEUE_MACRO_DEBUG behavior. 1787 178820160824: 1789 r304787 changed some ioctl interfaces between the iSCSI userspace 1790 programs and the kernel. ctladm, ctld, iscsictl, and iscsid must be 1791 rebuilt to work with new kernels. __FreeBSD_version has been bumped 1792 to 1200005. 1793 179420160818: 1795 The UDP receive code has been updated to only treat incoming UDP 1796 packets that were addressed to an L2 broadcast address as L3 1797 broadcast packets. It is not expected that this will affect any 1798 standards-conforming UDP application. The new behaviour can be 1799 disabled by setting the sysctl net.inet.udp.require_l2_bcast to 1800 0. 1801 180220160818: 1803 Remove the openbsd_poll system call. 1804 __FreeBSD_version has been bumped because of this. 1805 180620160708: 1807 The stable/11 branch has been created from head@r302406. 1808 1809After branch N is created, entries older than the N-2 branch point are removed 1810from this file. After stable/14 is branched and current becomes FreeBSD 15, 1811entries older than stable/12 branch point will be removed from current's 1812UPDATING file. 1813 1814COMMON ITEMS: 1815 1816 General Notes 1817 ------------- 1818 Sometimes, obscure build problems are the result of environment 1819 poisoning. This can happen because the make utility reads its 1820 environment when searching for values for global variables. To run 1821 your build attempts in an "environmental clean room", prefix all make 1822 commands with 'env -i '. See the env(1) manual page for more details. 1823 Occasionally a build failure will occur with "make -j" due to a race 1824 condition. If this happens try building again without -j, and please 1825 report a bug if it happens consistently. 1826 1827 When upgrading from one major version to another it is generally best to 1828 upgrade to the latest code in the currently installed branch first, then 1829 do an upgrade to the new branch. This is the best-tested upgrade path, 1830 and has the highest probability of being successful. Please try this 1831 approach if you encounter problems with a major version upgrade. Since 1832 the stable 4.x branch point, one has generally been able to upgrade from 1833 anywhere in the most recent stable branch to head / current (or even the 1834 last couple of stable branches). See the top of this file when there's 1835 an exception. 1836 1837 The update process will emit an error on an attempt to perform a build 1838 or install from a FreeBSD version below the earliest supported version. 1839 When updating from an older version the update should be performed one 1840 major release at a time, including running `make delete-old` at each 1841 step. 1842 1843 When upgrading a live system, having a root shell around before 1844 installing anything can help undo problems. Not having a root shell 1845 around can lead to problems if pam has changed too much from your 1846 starting point to allow continued authentication after the upgrade. 1847 1848 This file should be read as a log of events. When a later event changes 1849 information of a prior event, the prior event should not be deleted. 1850 Instead, a pointer to the entry with the new information should be 1851 placed in the old entry. Readers of this file should also sanity check 1852 older entries before relying on them blindly. Authors of new entries 1853 should write them with this in mind. 1854 1855 ZFS notes 1856 --------- 1857 When upgrading the boot ZFS pool to a new version (via zpool upgrade), 1858 always follow these three steps: 1859 1860 1) recompile and reinstall the ZFS boot loader and boot block 1861 (this is part of "make buildworld" and "make installworld") 1862 1863 2) update the ZFS boot block on your boot drive (only required when 1864 doing a zpool upgrade): 1865 1866 When booting on x86 via BIOS, use the following to update the ZFS boot 1867 block on the freebsd-boot partition of a GPT partitioned drive ada0: 1868 gpart bootcode -p /boot/gptzfsboot -i $N ada0 1869 The value $N will typically be 1. For EFI booting, see EFI notes. 1870 1871 3) zpool upgrade the root pool. New bootblocks will work with old 1872 pools, but not vice versa, so they need to be updated before any 1873 zpool upgrade. 1874 1875 Non-boot pools do not need these updates. 1876 1877 EFI notes 1878 --------- 1879 1880 There are two locations the boot loader can be installed into. The 1881 current location (and the default) is \efi\freebsd\loader.efi and using 1882 efibootmgr(8) to configure it. The old location, that must be used on 1883 deficient systems that don't honor efibootmgr(8) protocols, is the 1884 fallback location of \EFI\BOOT\BOOTxxx.EFI. Generally, you will copy 1885 /boot/loader.efi to this location, but on systems installed a long time 1886 ago the ESP may be too small and /boot/boot1.efi may be needed unless 1887 the ESP has been expanded in the meantime. 1888 1889 Recent systems will have the ESP mounted on /boot/efi, but older ones 1890 may not have it mounted at all, or mounted in a different 1891 location. Older arm SD images with MBR used /boot/msdos as the 1892 mountpoint. The ESP is a MSDOS filesystem. 1893 1894 The EFI boot loader rarely needs to be updated. For ZFS booting, 1895 however, you must update loader.efi before you do 'zpool upgrade' the 1896 root zpool, otherwise the old loader.efi may reject the upgraded zpool 1897 since it does not automatically understand some new features. 1898 1899 See loader.efi(8) and uefi(8) for more details. 1900 1901 To build a kernel 1902 ----------------- 1903 If you are updating from a prior version of FreeBSD (even one just 1904 a few days old), you should follow this procedure. It is the most 1905 failsafe as it uses a /usr/obj tree with a fresh mini-buildworld, 1906 1907 make kernel-toolchain 1908 make -DALWAYS_CHECK_MAKE buildkernel KERNCONF=YOUR_KERNEL_HERE 1909 make -DALWAYS_CHECK_MAKE installkernel KERNCONF=YOUR_KERNEL_HERE 1910 1911 To test a kernel once 1912 --------------------- 1913 If you just want to boot a kernel once (because you are not sure 1914 if it works, or if you want to boot a known bad kernel to provide 1915 debugging information) run 1916 make installkernel KERNCONF=YOUR_KERNEL_HERE KODIR=/boot/testkernel 1917 nextboot -k testkernel 1918 1919 To rebuild everything and install it on the current system. 1920 ----------------------------------------------------------- 1921 # Note: sometimes if you are running current you gotta do more than 1922 # is listed here if you are upgrading from a really old current. 1923 1924 <make sure you have good level 0 dumps> 1925 make buildworld 1926 make buildkernel KERNCONF=YOUR_KERNEL_HERE 1927 make installkernel KERNCONF=YOUR_KERNEL_HERE 1928 [1] 1929 <reboot in single user> [3] 1930 etcupdate -p [5] 1931 make installworld 1932 etcupdate -B [4] 1933 make delete-old [6] 1934 <reboot> 1935 1936 To cross-install current onto a separate partition 1937 -------------------------------------------------- 1938 # In this approach we use a separate partition to hold 1939 # current's root, 'usr', and 'var' directories. A partition 1940 # holding "/", "/usr" and "/var" should be about 2GB in 1941 # size. 1942 1943 <make sure you have good level 0 dumps> 1944 <boot into -stable> 1945 make buildworld 1946 make buildkernel KERNCONF=YOUR_KERNEL_HERE 1947 <maybe newfs current's root partition> 1948 <mount current's root partition on directory ${CURRENT_ROOT}> 1949 make installworld DESTDIR=${CURRENT_ROOT} -DDB_FROM_SRC 1950 make distribution DESTDIR=${CURRENT_ROOT} # if newfs'd 1951 make installkernel KERNCONF=YOUR_KERNEL_HERE DESTDIR=${CURRENT_ROOT} 1952 cp /etc/fstab ${CURRENT_ROOT}/etc/fstab # if newfs'd 1953 <edit ${CURRENT_ROOT}/etc/fstab to mount "/" from the correct partition> 1954 <reboot into current> 1955 <do a "native" rebuild/install as described in the previous section> 1956 <maybe install compatibility libraries from ports/misc/compat*> 1957 <reboot> 1958 1959 1960 To upgrade in-place from stable to current 1961 ---------------------------------------------- 1962 <make sure you have good level 0 dumps> 1963 make buildworld [9] 1964 make buildkernel KERNCONF=YOUR_KERNEL_HERE [8] 1965 make installkernel KERNCONF=YOUR_KERNEL_HERE 1966 [1] 1967 <reboot in single user> [3] 1968 etcupdate -p [5] 1969 make installworld 1970 etcupdate -B [4] 1971 make delete-old [6] 1972 <reboot> 1973 1974 Make sure that you've read the UPDATING file to understand the 1975 tweaks to various things you need. At this point in the life 1976 cycle of current, things change often and you are on your own 1977 to cope. The defaults can also change, so please read ALL of 1978 the UPDATING entries. 1979 1980 Also, if you are tracking -current, you must be subscribed to 1981 freebsd-current@freebsd.org. Make sure that before you update 1982 your sources that you have read and understood all the recent 1983 messages there. If in doubt, please track -stable which has 1984 much fewer pitfalls. 1985 1986 [1] If you have third party modules, such as vmware, you should disable 1987 them at this point so they don't crash your system on 1988 reboot. Alternatively, you should rebuild all the modules you have in 1989 your system and install them as well. If you are running -current, you 1990 should seriously consider placing all sources to all the modules for 1991 your system (or symlinks to them) in /usr/local/sys/modules so this 1992 happens automatically. If all your modules come from ports, then adding 1993 the port origin directories to PORTS_MODULES instead is also automatic 1994 and effective, eg: 1995 PORTS_MODULES+=x11/nvidia-driver 1996 1997 [3] From the bootblocks, boot -s, and then do 1998 fsck -p 1999 mount -u / 2000 mount -a 2001 sh /etc/rc.d/zfs start # mount zfs filesystem, if needed 2002 cd src # full path to source 2003 adjkerntz -i # if CMOS is wall time 2004 Also, when doing a major release upgrade, it is required that you boot 2005 into single user mode to do the installworld. 2006 2007 [4] Note: This step is non-optional. Failure to do this step 2008 can result in a significant reduction in the functionality of the 2009 system. Attempting to do it by hand is not recommended and those 2010 that pursue this avenue should read this file carefully, as well 2011 as the archives of freebsd-current and freebsd-hackers mailing lists 2012 for potential gotchas. See etcupdate(8) for more information. 2013 2014 [5] Usually this step is a no-op. However, from time to time 2015 you may need to do this if you get unknown user in the following 2016 step. 2017 2018 [6] This only deletes old files and directories. Old libraries 2019 can be deleted by "make delete-old-libs", but you have to make 2020 sure that no program is using those libraries anymore. 2021 2022 [8] The new kernel must be able to run existing binaries used by an 2023 installworld. When upgrading across major versions, the new kernel's 2024 configuration must include the correct COMPAT_FREEBSD<n> option for 2025 existing binaries (e.g. COMPAT_FREEBSD11 to run 11.x binaries). Failure 2026 to do so may leave you with a system that is hard to boot to recover. A 2027 GENERIC kernel will include suitable compatibility options to run 2028 binaries from older branches. Note that the ability to run binaries 2029 from unsupported branches is not guaranteed. 2030 2031 Make sure that you merge any new devices from GENERIC since the 2032 last time you updated your kernel config file. Options also 2033 change over time, so you may need to adjust your custom kernels 2034 for these as well. 2035 2036 [9] If CPUTYPE is defined in your /etc/make.conf, make sure to use the 2037 "?=" instead of the "=" assignment operator, so that buildworld can 2038 override the CPUTYPE if it needs to. 2039 2040 MAKEOBJDIRPREFIX must be defined in an environment variable, and 2041 not on the command line, or in /etc/make.conf. buildworld will 2042 warn if it is improperly defined. 2043FORMAT: 2044 2045This file contains a list, in reverse chronological order, of major 2046breakages in tracking -current. It is not guaranteed to be a complete 2047list of such breakages, and only contains entries since September 23, 2011. 2048If you need to see UPDATING entries from before that date, you will need 2049to fetch an UPDATING file from an older FreeBSD release. 2050 2051Copyright information: 2052 2053Copyright 1998-2009 M.
