1Updating Information for users of FreeBSD stable/14. 2 3This file is maintained and copyrighted by M. Warner Losh <[email protected]>. 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 1520240202: 16 Loader now also read configuration files listed in local_loader_conf_files. 17 Files listed here are the last ones read. And /boot/loader.conf.local was 18 moved from loader_conf_files to local_loader_conf_files leaving only 19 loader.conf and device.hints in loader_conf_files by default. 20 21 The following sequencing is applied: 22 23 1. Bootstrap: 24 /boot/defaults/loader.conf 25 26 2. Read loader_conf_files files: 27 /boot/device.hints 28 /boot/loader.conf 29 30 3. Read loader_conf_dirs files: 31 /boot/loader.conf.d/*.conf 32 33 4. And finally, rread local_loader_conf_files files: 34 /boot/loader.conf.local 35 3620240415: 37 MFC e0f3dc82727f: If you have an arm64 system that uses ACPI, you will 38 need to update your loader.efi in the ESP when you update past this 39 point. Detection of ACPI was moved earlier in the binary so the scripts 40 could use it, but old binaries don't have this, so we default to 'no 41 ACPI' in this case. 42 4320240218: 44 MFC of 713db49d06de changed 'struct ieee80211vap' internals in net80211. 45 Given we do not have enough spares and the struct is allocated by 46 drivers, all wireless drivers have to be recompiled. 47 __FreeBSD_version is updated to 1400509 to track this change. 48 4920240207: 50 sendmail 8.18.1 has been imported and merged. This version enforces 51 stricter RFC compliance by default, especially with respect to line 52 endings. This may cause issues with receiving messages from 53 non-compliant MTAs; please see the first 8.18.1 release note in 54 contrib/sendmail/RELEASE_NOTES for mitigations. 55 5620231113: 57 The WITHOUT_LLD_IS_LD option has been removed. When LLD is enabled 58 it is always installed as /usr/bin/ld. 59 6020240119: 61 Commit d34f4baaf138 changed the internal interface between 62 the nfscommon and nfscl modules. As such, both need to be 63 rebuilt from sources. Therefore, bump __FreeBSD_version 64 to 1400506. 65 6620231229: 67 Commit 925d9b3abac2 modified the internal API between 68 the nfscommon and nfscl modules. 69 As such, both of these modules need to be rebuilt from 70 sources. Therefore, the __FreeBSD_version has been bumped 71 to 1400503. 72 7320231224: 74 Commits acc704b36192 and b8e137d8d32d both modified the 75 internal API between the kgssapi and krpc modules. 76 As such, both of these modules need to be rebuilt from 77 sources. 78 As such, __FreeBSD_version has been bumped to 1400502. 79 8020230924: 81 Enable splitting out pkgbase manpages into separate packages by 82 default. To disable this, set WITHOUT_MANSPLITPKG=yes in src.conf. 83 84 8520230924: 86 Move standard include files to the clibs-dev package and move clang 87 internal libraries and headers to clang and clang-dev. Upgrading systems 88 installed using pkgbase past this change involves extra steps to allow 89 for these file moves: 90 91 pkg upgrade -y FreeBSD-utilities 92 pkg upgrade -y FreeBSD-utilities-dev 93 pkg upgrade -y 94 9520230824: 96 __FreeBSD_version 1400097 after the branching stable/14 from main. 97 9820230817: 99 Serial communication (in boot loaders, kernel, and userland) has 100 been changed to default to 115200 bps, in line with common industry 101 practice and typcial firmware serial console redirection 102 configuration. 103 104 Note that the early x86 BIOS bootloader (i.e., boot0sio) does not 105 support rates above 9600 bps and is not changed. boot0sio users may 106 set BOOT_COMCONSOLE_SPEED=9600 to use 9600 for all of the boot 107 components, or use the standard boot0 and have the boot2 stage start 108 with the serial port at 115200. 109 11020230807: 111 Following the general removal of MIPS support, the ath(4) AHB bus- 112 frontend has been removed, too, and building of the PCI support is 113 integrated with the ath(4) main module again. As a result, there's 114 no longer a need for if_ath_pci_load="YES" in /boot/loader.conf or 115 "device ath_pci" in the kernel configuration. 116 11720230803: 118 MAXCPU has been increased to 1024 in the amd64 GENERIC kernel config. 119 Out-of-tree kernel modules will need to be rebuilt. 120 12120230724: 122 CAM has been mechanically updated s/u_int(64|32|16|8)_t/uint\1_t/g 123 to move to the standard uintXX_t types from the old, traditional 124 BSD u_intXX_t types. This should be a NOP, but may cause problems 125 for out of tree changes. The SIMs were not updated since most of 126 the old u_intXX_t uses weren't due to CAM interfaces. 127 12820230629: 129 The heuristic for detecting old chromebooks with an EC bug that requires 130 atkbdc driver workarounds has changed. There should be no functional 131 change, but if your old chromebook's keyboard stops working, please 132 file a PR and assign it to imp. 133 13420230623: 135 OpenSSL has been updated to version 3.0, including changes throughout 136 the base system. It is important to rebuild third-party software 137 after upgrading. 138 13920230619: 140 To enable pf rdr rules for connections initiated from the host, pf 141 filter rules can be optionally enabled for packets delivered 142 locally. This can change the behavior of rules which match packets 143 delivered to lo0. To enable this feature: 144 145 sysctl net.pf.filter_local=1 146 service pf restart 147 148 When enabled, its best to ensure that packets delivered locally are not 149 filtered, e.g. by adding a 'skip on lo' rule. 150 15120230613: 152 Improvements to libtacplus(8) mean that tacplus.conf(5) now 153 follows POSIX shell syntax rules. This may cause TACACS+ 154 authentication to fail if the shared secret contains a single 155 quote, double quote, or backslash character which isn't 156 already properly quoted or escaped. 157 15820230612: 159 Belatedly switch the default nvme block device on x86 from nvd to nda. 160 nda created nvd compatibility links by default, so this should be a 161 nop. If this causes problems for your application, set hw.nvme.use_nvd=1 162 in your loader.conf or add `options NVME_USE_NVD=1` to your kernel 163 config. To disable the nvd compatibility aliases, add 164 kern.cam.nda.nvd_compat=0 to loader.conf. The default has been nda on 165 all non-x86 platforms for some time now. If you need to fall back, 166 please email [email protected] about why. 167 168 Encrypted swap partitions need to be changed from nvd to nda if you 169 migrate, or you need to use the above to switch back to nvd. 170 17120230422: 172 Remove portsnap(8). Users are encouraged to obtain the ports tree 173 using git instead. 174 17520230420: 176 Add jobs.mk to save typing. Enables -j${JOB_MAX} and logging 177 eg. 178 make buildworld-jobs 179 runs 180 make -j${JOB_MAX} buildworld > ../buildworld.log 2>&1 181 182 where JOB_MAX is derrived from ncpus in local.sys.mk if not set in env. 183 18420230316: 185 Video related devices for some arm devices have been renamed. 186 If you have a custom kernel config and want to use hdmi output on 187 IMX6 board you need to add "device dwc_hdmi" "device imx6_hdmi" and 188 "device imx6_ipu" to it. 189 If you have a custom kernel config and want to use hdmi output on 190 TI AM335X board you need to add "device tda19988" to it. 191 If you add "device hdmi" in it you need to remove it as it doesn't 192 exist anymore. 193 19420230221: 195 Introduce new kernel options KBD_DELAY1 and KBD_DELAY2. See atkbdc(4) 196 for details. 197 19820230206: 199 sshd now defaults to having X11Forwarding disabled, following upstream. 200 Administrators who wish to enable X11Forwarding should add 201 `X11Forwarding yes` to /etc/ssh/sshd_config. 202 20320230204: 204 Since commit 75d41cb6967 Huawei 3G/4G LTE Mobile Devices do not default 205 to ECM, but NCM mode and need u3g and ucom modules loaded. See cdce(4). 206 20720230130: 208 As of commit 7c40e2d5f685, the dependency on netlink(4) has been added 209 to the linux_common(4) module. Users relying on linux_common may need 210 to complile netlink(4) module if it is not present in their kernel. 211 21220230126: 213 The WITHOUT_CXX option has been removed. C++ components in the base 214 system are now built unconditionally. 215 21620230113: 217 LinuxKPI pci.h changes may require out-of-tree drivers to be recompiled. 218 Bump _FreeBSD_version to 1400078 to be able to detect this change. 219 22020221212: 221 llvm-objump is now always installed as objdump. Previously there was 222 no /usr/bin/objdump unless the WITH_LLVM_BINUTILS knob was used. 223 224 Some LLVM objdump options have a different output format compared to 225 GNU objdump; readelf is available for inspecting ELF files, and GNU 226 objdump is available from the devel/binutils port or package. 227 22820221205: 229 dma(8) has replaced sendmail(8) as the default mta. For people willing 230 to reenable sendmail(8): 231 232 $ cp /usr/share/examples/sendmail/mailer.conf /etc/mail/mailer.conf 233 234 and add sendmail_enable="YES" to rc.conf. 235 23620221204: 237 hw.bus.disable_failed_devices has changed from 'false' to 'true' by 238 default. Now if newbus succeeds in probing a device, but fails to attach 239 the device, we'll disable the device. In the past, we'd keep retrying 240 the device on each new driver loaded. To get that behavior now, one 241 needs to use devctl to re-enable the device, and reprobe it (or set 242 the sysctl/tunable hw.bus.disable_failed_devices=false). 243 244 NOTE: This was reverted 20221205 due to unexpected compatibility issues 245 24620221122: 247 pf no longer accepts 'scrub fragment crop' or 'scrub fragment drop-ovl'. 248 These configurations are no longer automatically reinterpreted as 249 'scrub fragment reassemble'. 250 25120221121: 252 The WITHOUT_CLANG_IS_CC option has been removed. When Clang is enabled 253 it is always installed as /usr/bin/cc (and c++, cpp). 254 25520221026: 256 Some programs have been moved into separate packages. It is recommended 257 for pkgbase users to do: 258 259 pkg install FreeBSD-dhclient FreeBSD-geom FreeBSD-resolvconf \ 260 FreeBSD-devd FreeBSD-devmatch 261 262 after upgrading to restore all the component that were previously 263 installed. 264 26520221002: 266 OPIE has been removed from the base system. If needed, it can 267 be installed from ports (security/opie) or packages (opie). 268 Otherwise, make sure that your PAM policies do not reference 269 pam_opie or pam_opieaccess. 270 27120220610: 272 LinuxKPI pm.h changes require an update to the latest drm-kmod version 273 before re-compiling to avoid errors. 274 27520211230: 276 The macros provided for the manipulation of CPU sets (e.g. CPU_AND) 277 have been modified to take 2 source arguments instead of only 1. 278 Externally maintained sources that use these macros will have to 279 be adapted. The FreeBSD version has been bumped to 1400046 to 280 reflect this change. 281 28220211214: 283 A number of the kernel include files are able to be included by 284 themselves. A test has been added to buildworld to enforce this. 285 28620211209: 287 Remove mips as a recognized target. This starts the decommissioning of 288 mips support in FreeBSD. mips related items will be removed wholesale in 289 the coming days and weeks. 290 291 This broke the NO_CLEAN build for some people. Either do a clean build 292 or touch 293 lib/clang/include/llvm/Config/Targets.def 294 lib/clang/include/llvm/Config/AsmParsers.def 295 lib/clang/include/llvm/Config/Disassemblers.def 296 lib/clang/include/llvm/Config/AsmPrinters.def 297 before the build to force everything to rebuild that needs to. 298 29920211202: 300 Unbound support for RFC8375: The special-use domain 'home.arpa' is 301 by default blocked. To unblock it use a local-zone nodefault 302 statement in unbound.conf: 303 local-zone: "home.arpa." nodefault 304 305 Or use another type of local-zone to override with your choice. 306 307 The reason for this is discussed in Section 6.1 of RFC8375: 308 Because 'home.arpa.' is not globally scoped and cannot be secured 309 using DNSSEC based on the root domain's trust anchor, there is no way 310 to tell, using a standard DNS query, in which homenet scope an answer 311 belongs. Consequently, users may experience surprising results with 312 such names when roaming to different homenets. 313 31420211110: 315 Commit b8d60729deef changed the TCP congestion control framework so 316 that any of the included congestion control modules could be 317 the single module built into the kernel. Previously newreno 318 was automatically built in through direct reference. As of 319 this commit you are required to declare at least one congestion 320 control module (e.g. 'options CC_NEWRENO') and to also declare a 321 default using the CC_DEFAULT option (e.g. options CC_DEFAULT="newreno\"). 322 The GENERIC configuration includes CC_NEWRENO and defines newreno 323 as the default. If no congestion control option is built into the 324 kernel and you are including networking, the kernel compile will 325 fail. Also if no default is declared the kernel compile will fail. 326 32720211118: 328 Mips has been removed from universe builds. It will be removed from the 329 tree shortly. 330 33120211106: 332 Commit f0c9847a6c47 changed the arguments for VOP_ALLOCATE. 333 The NFS modules must be rebuilt from sources and any out 334 of tree file systems that implement their own VOP_ALLOCATE 335 may need to be modified. 336 33720211022: 338 The synchronous PPP kernel driver sppp(4) has been removed. 339 The cp(4) and ce(4) drivers are now always compiled with netgraph(4) 340 support, formerly enabled by NETGRAPH_CRONYX option. 341 34220211020: 343 sh(1) is now the default shell for the root user. To force root to use 344 the csh shell, please run the following command as root: 345 346 # chsh -s csh 347 34820211004: 349 Ncurses distribution has been split between libtinfow and libncurses 350 with libncurses.so becoming a linker (ld) script to seamlessly link 351 to libtinfow as needed. Bump _FreeBSD_version to 1400035 to reflect 352 this change. 353 35420210923: 355 As of commit 8160a0f62be6, the dummynet module no longer depends on the 356 ipfw module. Dummynet can now be used by pf as well as ipfw. As such 357 users who relied on this dependency may need to include ipfw in the 358 list of modules to load on their systems. 359 36020210922: 361 As of commit 903873ce1560, the mixer(8) utility has got a slightly 362 new syntax. Please refer to the mixer(8) manual page for more 363 information. The old mixer utility can be installed from ports: 364 audio/freebsd-13-mixer 365 36620210911: 367 As of commit 55089ef4f8bb, the global variable nfs_maxcopyrange has 368 been deleted from the nfscommon.ko. As such, nfsd.ko must be built 369 from up to date sources to avoid an undefined reference when 370 being loaded. 371 37220210817: 373 As of commit 62ca9fc1ad56 OpenSSL no longer enables kernel TLS 374 by default. Users can enable kernel TLS via the "KTLS" SSL 375 option. This can be enabled globally by using a custom 376 OpenSSL config file via OPENSSL_CONF or via an 377 application-specific configuration option for applications 378 which permit setting SSL options via SSL_CONF_cmd(3). 379 38020210811: 381 Commit 3ad1e1c1ce20 changed the internal KAPI between the NFS 382 modules. Therefore, all need to be rebuilt from sources. 383 38420210730: 385 Commit b69019c14cd8 removes pf's DIOCGETSTATESNV ioctl. 386 As of be70c7a50d32 it is no longer used by userspace, but it does mean 387 users may not be able to enumerate pf states if they update the kernel 388 past b69019c14cd8 without first updating userspace past be70c7a50d32. 389 39020210729: 391 As of commit 01ad0c007964 if_bridge member interfaces can no longer 392 change their MTU. Changing the MTU of the bridge itself will change the 393 MTU on all member interfaces instead. 394 39520210716: 396 Commit ee29e6f31111 changed the internal KAPI between the nfscommon 397 and nfsd modules. Therefore, both need to be rebuilt from sources. 398 Bump __FreeBSD_version to 1400026 for this KAPI change. 399 40020210715: 401 The 20210707 awk update brought in a change in behavior. This has 402 been corrected as of d4d252c49976. Between these dates, if you 403 installed a new awk binary, you may not be able to build a new 404 kernel because the change in behavior affected the genoffset 405 script used to build the kernel. If you did update, the fix is 406 to update your sources past the above hash and do 407 % cd usr.bin/awk 408 % make clean all 409 % sudo -E make install 410 to enable building kernels again. 411 41220210708: 413 Commit 1e0a518d6548 changed the internal KAPI between the NFS 414 modules. They all need to be rebuilt from sources. I did not 415 bump __FreeBSD_version, since it was bumped recently. 416 41720210707: 418 awk has been updated to the latest one-true-awk version 20210215. 419 This contains a number of minor bug fixes. 420 42120210624: 422 The NFSv4 client now uses the highest minor version of NFSv4 423 supported by the NFSv4 server by default instead of minor version 0, 424 for NFSv4 mounts. 425 The "minorversion" mount option may be used to override this default. 426 42720210618: 428 Bump __FreeBSD_version to 1400024 for LinuxKPI changes. 429 Most notably netdev.h can change now as the (last) dependencies 430 (mlx4/ofed) are now using struct ifnet directly, but also for PCI 431 additions and others. 432 43320210618: 434 The directory "blacklisted" under /usr/share/certs/ has been 435 renamed to "untrusted". 436 43720210611: 438 svnlite has been removed from base. Should you need svn for any reason 439 please install the svn package or port. 440 44120210611: 442 Commit e1a907a25cfa changed the internal KAPI between the krpc 443 and nfsserver. As such, both modules must be rebuilt from 444 sources. Bump __FreeBSD_version to 1400022. 445 44620210610: 447 The an(4) driver has been removed from FreeBSD. 448 44920210608: 450 The vendor/openzfs branch was renamed to vendor/openzfs/legacy to 451 start tracking OpenZFS upstream more closely. Please see 452https://lists.freebsd.org/archives/freebsd-current/2021-June/000153.html 453 for details on how to correct any errors that might result. The 454 short version is that you need to remove the old branch locally: 455 git update-ref -d refs/remotes/freebsd/vendor/openzfs 456 (assuming your upstream origin is named 'freebsd'). 457 45820210525: 459 Commits 17accc08ae15 and de102f870501 add new files to LinuxKPI 460 which break drm-kmod. In addition various other additions where 461 committed. Bump __FreeBSD_version to 1400015 to be able to 462 detect this. 463 46420210513: 465 Commit ca179c4d74f2 changed the package in which the OpenSSL 466 libraries and utilities are packaged. 467 It is recommended for pkgbase user to do: 468 pkg install -f FreeBSD-openssl 469 before pkg upgrade otherwise some dependencies might not be met 470 and pkg will stop working as libssl will not be present anymore 471 on the system. 472 47320210426: 474 Commit 875977314881 changed the internal KAPI between 475 the nfsd and nfscommon modules. As such these modules 476 need to be rebuilt from sources. 477 Without this patch in your NFSv4.1/4.2 server, enabling 478 delegations by setting vfs.nfsd.issue_delegations non-zero 479 is not recommended. 480 48120210411: 482 Commit 7763814fc9c2 changed the internal KAPI between 483 the krpc and NFS. As such, the krpc, nfscommon and 484 nfscl modules must all be rebuilt from sources. 485 Without this patch, NFSv4.1/4.2 mounts should not 486 be done with the nfscbd(8) daemon running, to avoid 487 needing a working back channel for server->client RPCs. 488 48920210330: 490 Commit 01ae8969a9ee fixed the NFSv4.1/4.2 server so that it 491 handles binding of the back channel as required by RFC5661. 492 Until this patch is in your server, avoid use of the "nconnects" 493 mount option for Linux NFSv4.1/4.2 mounts. 494 49520210225: 496 For 64-bit architectures the base system is now built with Position 497 Independent Executable (PIE) support enabled by default. It may be 498 disabled using the WITHOUT_PIE knob. A clean build is required. 499 50020210128: 501 Various LinuxKPI functionality was added which conflicts with DRM. 502 Please update your drm-kmod port to after the __FreeBSD_version 1400003 503 update. 504 50520210108: 506 PC Card attachments for all devices have been removed. In the case of 507 wi and cmx, the entire drivers were removed because they were only 508 PC Card devices. FreeBSD_version 1300134 should be used for this 509 since it was bumped so recently. 510 51120210107: 512 Transport-independent parts of HID support have been split off the USB 513 code in to separate subsystem. Kernel configs which include one of 514 ums, ukbd, uhid, atp, wsp, wmt, uaudio, ugold or ucycom drivers should 515 be updated with adding of "device hid" line. 516 51720210105: 518 ncurses installation has been modified to only keep the widechar 519 enabled version. Incremental build is broken for that change, so it 520 requires a clean build. 521 52220201223: 523 The FreeBSD project has migrated from Subversion to Git. Temporary 524 instructions can be found at 525 https://github.com/bsdimp/freebsd-git-docs/blob/main/src-cvt.md 526 and other documents in that repo. 527 52820201216: 529 The services database has been updated to cover more of the basic 530 services expected in a modern system. The database is big enough 531 that it will cause issues in mergemaster in Releases previous to 532 12.2 and 11.3, or in very old current systems from before r358154. 533 53420201215: 535 Obsolete in-tree GDB 6.1.1 has been removed. GDB (including kgdb) 536 may be installed from ports or packages. 537 53820201124: 539 ping6 has been merged into ping. It can now be called as "ping -6". 540 See ping(8) for details. 541 54220201108: 543 Default value of net.add_addr_allfibs has been changed to 0. 544 If you have multi-fib configuration and rely on existence of all 545 interface routes in every fib, you need to set the above sysctl to 1. 546 54720201030: 548 The internal pre-processor in the calendar(1) program has been 549 extended to support more C pre-processor commands (e.g. #ifdef, #else, 550 and #undef) and to detect unbalanced conditional statements. 551 Error messages have been extended to include the filename and line 552 number if processing stops to help fixing malformed data files. 553 55420201026: 555 All the data files for the calendar(1) program, except calendar.freebsd, 556 have been moved to the deskutils/calendar-data port, much like the 557 jewish calendar entries were moved to deskutils/hebcal years ago. After 558 make delete-old-files, you need to install it to retain full 559 functionality. calendar(1) will issue a reminder for files it can't 560 find. 561 56220200923: 563 LINT files are no longer generated. We now include the relevant NOTES 564 files. Note: This may cause conflicts with updating in some cases. 565 find sys -name LINT\* -delete 566 is suggested across this commit to remove the generated LINT files. 567 568 If you have tried to update with generated files there, the svn 569 command you want to un-auger the tree is 570 cd sys/amd64/conf 571 svn revert -R . 572 and then do the above find from the top level. Substitute 'amd64' 573 above with where the error message indicates a conflict. 574 57520200824: 576 OpenZFS support has been integrated. Do not upgrade root pools until 577 the loader is updated to support zstd. Furthermore, we caution against 578 'zpool upgrade' for the next few weeks. The change should be transparent 579 unless you want to use new features. 580 581 Not all "NO_CLEAN" build scenarios work across these changes. Many 582 scenarios have been tested and fixed, but rebuilding kernels without 583 rebuilding world may fail. 584 585 The ZFS cache file has moved from /boot to /etc to match the OpenZFS 586 upstream default. A fallback to /boot has been added for mountroot. 587 588 Pool auto import behavior at boot has been moved from the kernel module 589 to an explicit "zpool import -a" in one of the rc scripts enabled by 590 zfs_enable=YES. This means your non-root zpools won't auto import until 591 you upgrade your /etc/rc.d files. 592 59320200824: 594 The resume code now notifies devd with the 'kernel' system 595 rather than the old 'kern' subsystem to be consistent with 596 other use. The old notification will be created as well, but 597 will be removed prior to FreeBSD 14.0. 598 59920200821: 600 r362275 changed the internal API between the kernel RPC and the 601 NFS modules. As such, all the modules must be recompiled from 602 sources. 603 60420200817: 605 r364330 modified the internal API used between the NFS modules. 606 As such, all the NFS modules must be re-compiled from sources. 607 60820200816: 609 Clang, llvm, lld, lldb, compiler-rt, libc++, libunwind and openmp have 610 been upgraded to 11.0.0. Please see the 20141231 entry below for 611 information about prerequisites and upgrading, if you are not already 612 using clang 3.5.0 or higher. 613 61420200810: 615 r364092 modified the internal ABI used between the kernel NFS 616 modules. As such, all of these modules need to be rebuilt 617 from sources, so a version bump was done. 618 61920200807: 620 Makefile.inc has been updated to work around the issue documented in 621 20200729. It was a case where the optimization of using symbolic links 622 to point to binaries created a situation where we'd run new binaries 623 with old libraries starting midway through the installworld process. 624 62520200729: 626 r363679 has redefined some undefined behavior in regcomp(3); notably, 627 extraneous escapes of most ordinary characters will no longer be 628 accepted. An exp-run has identified all of the problems with this in 629 ports, but other non-ports software may need extra escapes removed to 630 continue to function. 631 632 Because of this change, installworld may encounter the following error 633 from rtld: Undefined symbol "regcomp@FBSD_1.6" -- It is imperative that 634 you do not halt installworld. Instead, let it run to completion (whether 635 successful or not) and run installworld once more. 636 63720200627: 638 A new implementation of bc and dc has been imported in r362681. This 639 implementation corrects non-conformant behavior of the previous bc 640 and adds GNU bc compatible options. It offers a number of extensions, 641 is much faster on large values, and has support for message catalogs 642 (a number of languages are already supported, contributions of further 643 languages welcome). The option WITHOUT_GH_BC can be used to build the 644 world with the previous versions of bc and dc. 645 64620200625: 647 r362639 changed the internal API used between the NFS kernel modules. 648 As such, they all need to be rebuilt from sources. 649 65020200613: 651 r362158 changed the arguments for VFS_CHECKEXP(). As such, any 652 out of tree file systems need to be modified and rebuilt. 653 Also, any file systems that are modules must be rebuilt. 654 65520200604: 656 read(2) of a directory fd is now rejected by default. root may 657 re-enable it for system root only on non-ZFS filesystems with the 658 security.bsd.allow_read_dir sysctl(8) MIB if 659 security.bsd.suser_enabled=1. 660 661 It may be advised to setup aliases for grep to default to `-d skip` if 662 commonly non-recursively grepping a list that includes directories and 663 the potential for the resulting stderr output is not tolerable. Example 664 aliases are now installed, commented out, in /root/.cshrc and 665 /root/.shrc. 666 66720200523: 668 Clang, llvm, lld, lldb, compiler-rt, libc++, libunwind and openmp have 669 been upgraded to 10.0.1. Please see the 20141231 entry below for 670 information about prerequisites and upgrading, if you are not already 671 using clang 3.5.0 or higher. 672 67320200512: 674 Support for obsolete compilers has been removed from the build system. 675 Clang 6 and GCC 6.4 are the minimum supported versions. 676 67720200424: 678 closefrom(2) has been moved under COMPAT12, and replaced in libc with a 679 stub that calls close_range(2). If using a custom kernel configuration, 680 you may want to ensure that the COMPAT_FREEBSD12 option is included, as 681 a slightly older -CURRENT userland and older FreeBSD userlands may not 682 be functional without closefrom(2). 683 68420200414: 685 Upstream DTS from Linux 5.6 was merged and they now have the SID 686 and THS (Secure ID controller and THermal Sensor) node present. 687 The DTB overlays have now been removed from the tree for the H3/H5 and 688 A64 SoCs and the aw_sid and aw_thermal driver have been updated to 689 deal with upstream DTS. If you are using those overlays you need to 690 remove them from loader.conf and update the DTBs on the FAT partition. 691 69220200310: 693 Clang, llvm, lld, lldb, compiler-rt, libc++, libunwind and openmp have 694 been upgraded to 10.0.0. Please see the 20141231 entry below for 695 information about prerequisites and upgrading, if you are not already 696 using clang 3.5.0 or higher. 697 69820200309: 699 The amd(8) automount daemon has been removed from the source tree. 700 As of FreeBSD 10.1 autofs(5) is the preferred tool for automounting. 701 amd is still available in the sysutils/am-utils port. 702 70320200301: 704 Removed brooktree driver (bktr.4) from the tree. 705 70620200229: 707 The WITH_GPL_DTC option has been removed. The BSD-licenced device tree 708 compiler in usr.bin/dtc is used on all architectures which use dtc, and 709 the GPL dtc is available (if needed) from the sysutils/dtc port. 710 71120200229: 712 The WITHOUT_LLVM_LIBUNWIND option has been removed. LLVM's libunwind 713 is used by all supported CPU architectures. 714 71520200229: 716 GCC 4.2.1 has been removed from the tree. The WITH_GCC, 717 WITH_GCC_BOOTSTRAP, and WITH_GNUCXX options are no longer available. 718 Users who wish to build FreeBSD with GCC must use the external toolchain 719 ports or packages. 720 72120200220: 722 ncurses has been updated to a newer version (6.2-20200215). Given the ABI 723 has changed, users will have to rebuild all the ports that are linked to 724 ncurses. 725 72620200217: 727 The size of struct vnet and the magic cookie have changed. 728 Users need to recompile libkvm and all modules using VIMAGE 729 together with their new kernel. 730 73120200212: 732 Defining the long deprecated NO_CTF, NO_DEBUG_FILES, NO_INSTALLLIB, 733 NO_MAN, NO_PROFILE, and NO_WARNS variables is now an error. Update 734 your Makefiles and scripts to define MK_<var>=no instead as required. 735 736 One exception to this is that program or library Makefiles should 737 define MAN to empty rather than setting MK_MAN=no. 738 73920200108: 740 Clang/LLVM is now the default compiler and LLD the default 741 linker for riscv64. 742 74320200107: 744 make universe no longer uses GCC 4.2.1 on any architectures. 745 Architectures not supported by in-tree Clang/LLVM require an 746 external toolchain package. 747 74820200104: 749 GCC 4.2.1 is now not built by default, as part of the GCC 4.2.1 750 retirement plan. Specifically, the GCC, GCC_BOOTSTRAP, and GNUCXX 751 options default to off for all supported CPU architectures. As a 752 short-term transition aid they may be enabled via WITH_* options. 753 GCC 4.2.1 is expected to be removed from the tree on 2020-03-31. 754 75520200102: 756 Support for armv5 has been disconnected and is being removed. The 757 machine combination MACHINE=arm MACHINE_ARCH=arm is no longer valid. 758 You must now use a MACHINE_ARCH of armv6 or armv7. The default 759 MACHINE_ARCH for MACHINE=arm is now armv7. 760 76120191226: 762 Clang/LLVM is now the default compiler for all powerpc architectures. 763 LLD is now the default linker for powerpc64. The change for powerpc64 764 also includes a change to the ELFv2 ABI, incompatible with the existing 765 ABI. 766 76720191226: 768 Kernel-loadable random(4) modules are no longer unloadable. 769 77020191222: 771 Clang, llvm, lld, lldb, compiler-rt, libc++, libunwind and openmp have 772 been upgraded to 9.0.1. Please see the 20141231 entry below for 773 information about prerequisites and upgrading, if you are not already 774 using clang 3.5.0 or higher. 775 77620191212: 777 r355677 has modified the internal interface used between the 778 NFS modules in the kernel. As such, they must all be upgraded 779 simultaneously. I will do a version bump for this. 780 78120191205: 782 The root certificates of the Mozilla CA Certificate Store have been 783 imported into the base system and can be managed with the certctl(8) 784 utility. If you have installed the security/ca_root_nss port or package 785 with the ETCSYMLINK option (the default), be advised that there may be 786 differences between those included in the port and those included in 787 base due to differences in nss branch used as well as general update 788 frequency. Note also that certctl(8) cannot manage certs in the 789 format used by the security/ca_root_nss port. 790 79120191120: 792 The amd(8) automount daemon has been disabled by default, and will be 793 removed in the future. As of FreeBSD 10.1 the autofs(5) is available 794 for automounting. 795 79620191107: 797 The nctgpio and wbwd drivers have been moved to the superio bus. 798 If you have one of these drivers in a kernel configuration, then 799 you should add device superio to it. If you use one of these drivers 800 as a module and you compile a custom set of modules, then you should 801 add superio to the set. 802 80320191021: 804 KPIs for network drivers to access interface addresses have changed. 805 Users need to recompile NIC driver modules together with kernel. 806 80720191021: 808 The net.link.tap.user_open sysctl no longer prevents user opening of 809 already created /dev/tapNN devices. Access is still controlled by 810 node permissions, just like tun devices. The net.link.tap.user_open 811 sysctl is now used only to allow users to perform devfs cloning of 812 tap devices, and the subsequent open may not succeed if the user is not 813 in the appropriate group. This sysctl may be deprecated/removed 814 completely in the future. 815 81620191009: 817 mips, powerpc, and sparc64 are no longer built as part of 818 universe / tinderbox unless MAKE_OBSOLETE_GCC is defined. If 819 not defined, mips, powerpc, and sparc64 builds will look for 820 the xtoolchain binaries and if installed use them for universe 821 builds. As llvm 9.0 becomes vetted for these architectures, they 822 will be removed from the list. 823 82420191009: 825 Clang, llvm, lld, lldb, compiler-rt, libc++, libunwind and openmp have 826 been upgraded to 9.0.0. Please see the 20141231 entry below for 827 information about prerequisites and upgrading, if you are not already 828 using clang 3.5.0 or higher. 829 83020191003: 831 The hpt27xx, hptmv, hptnr, and hptrr drivers have been removed from 832 GENERIC. They are available as modules and can be loaded by adding 833 to /boot/loader.conf hpt27xx_load="YES", hptmv_load="YES", 834 hptnr_load="YES", or hptrr_load="YES", respectively. 835 83620190913: 837 ntpd no longer by default locks its pages in memory, allowing them 838 to be paged out by the kernel. Use rlimit memlock to restore 839 historic BSD behaviour. For example, add "rlimit memlock 32" 840 to ntp.conf to lock up to 32 MB of ntpd address space in memory. 841 84220190823: 843 Several of ping6's options have been renamed for better consistency 844 with ping. If you use any of -ARWXaghmrtwx, you must update your 845 scripts. See ping6(8) for details. 846 84720190727: 848 The vfs.fusefs.sync_unmount and vfs.fusefs.init_backgrounded sysctls 849 and the "-o sync_unmount" and "-o init_backgrounded" mount options have 850 been removed from mount_fusefs(8). You can safely remove them from 851 your scripts, because they had no effect. 852 853 The vfs.fusefs.fix_broken_io, vfs.fusefs.sync_resize, 854 vfs.fusefs.refresh_size, vfs.fusefs.mmap_enable, 855 vfs.fusefs.reclaim_revoked, and vfs.fusefs.data_cache_invalidate 856 sysctls have been removed. If you felt the need to set any of them to 857 a non-default value, please tell [email protected] why. 858 85920190713: 860 Default permissions on the /var/account/acct file (and copies of it 861 rotated by periodic daily scripts) are changed from 0644 to 0640 862 because the file contains sensitive information that should not be 863 world-readable. If the /var/account directory must be created by 864 rc.d/accounting, the mode used is now 0750. Admins who use the 865 accounting feature are encouraged to change the mode of an existing 866 /var/account directory to 0750 or 0700. 867 86820190620: 869 Entropy collection and the /dev/random device are no longer optional 870 components. The "device random" option has been removed. 871 Implementations of distilling algorithms can still be made loadable 872 with "options RANDOM_LOADABLE" (e.g., random_fortuna.ko). 873 87420190612: 875 Clang, llvm, lld, lldb, compiler-rt, libc++, libunwind and openmp have 876 been upgraded to 8.0.1. Please see the 20141231 entry below for 877 information about prerequisites and upgrading, if you are not already 878 using clang 3.5.0 or higher. 879 88020190608: 881 A fix was applied to i386 kernel modules to avoid panics with 882 dpcpu or vnet. Users need to recompile i386 kernel modules 883 having pcpu or vnet sections or they will refuse to load. 884 88520190513: 886 User-wired pages now have their own counter, 887 vm.stats.vm.v_user_wire_count. The vm.max_wired sysctl was renamed 888 to vm.max_user_wired and changed from an unsigned int to an unsigned 889 long. bhyve VMs wired with the -S are now subject to the user 890 wiring limit; the vm.max_user_wired sysctl may need to be tuned to 891 avoid running into the limit. 892 89320190507: 894 The IPSEC option has been removed from GENERIC. Users requiring 895 ipsec(4) must now load the ipsec(4) kernel module. 896 89720190507: 898 The tap(4) driver has been folded into tun(4), and the module has been 899 renamed to tuntap. You should update any kld_list="if_tap" or 900 kld_list="if_tun" entries in /etc/rc.conf, if_tap_load="YES" or 901 if_tun_load="YES" entries in /boot/loader.conf to load the if_tuntap 902 module instead, and "device tap" or "device tun" entries in kernel 903 config files to select the tuntap device instead. 904 90520190418: 906 The following knobs have been added related to tradeoffs between 907 safe use of the random device and availability in the absence of 908 entropy: 909 910 kern.random.initial_seeding.bypass_before_seeding: tunable; set 911 non-zero to bypass the random device prior to seeding, or zero to 912 block random requests until the random device is initially seeded. 913 For now, set to 1 (unsafe) by default to restore pre-r346250 boot 914 availability properties. 915 916 kern.random.initial_seeding.read_random_bypassed_before_seeding: 917 read-only diagnostic sysctl that is set when bypass is enabled and 918 read_random(9) is bypassed, to enable programmatic handling of this 919 initial condition, if desired. 920 921 kern.random.initial_seeding.arc4random_bypassed_before_seeding: 922 Similar to the above, but for arc4random(9) initial seeding. 923 924 kern.random.initial_seeding.disable_bypass_warnings: tunable; set 925 non-zero to disable warnings in dmesg when the same conditions are 926 met as for the diagnostic sysctls above. Defaults to zero, i.e., 927 produce warnings in dmesg when the conditions are met. 928 92920190416: 930 The loadable random module KPI has changed; the random_infra_init() 931 routine now requires a 3rd function pointer for a bool (*)(void) 932 method that returns true if the random device is seeded (and 933 therefore unblocked). 934 93520190404: 936 r345895 reverts r320698. This implies that an nfsuserd(8) daemon 937 built from head sources between r320757 (July 6, 2017) and 938 r338192 (Aug. 22, 2018) will not work unless the "-use-udpsock" 939 is added to the command line. 940 nfsuserd daemons built from head sources that are post-r338192 are 941 not affected and should continue to work. 942 94320190320: 944 The fuse(4) module has been renamed to fusefs(4) for consistency with 945 other filesystems. You should update any kld_load="fuse" entries in 946 /etc/rc.conf, fuse_load="YES" entries in /boot/loader.conf, and 947 "options FUSE" entries in kernel config files. 948 94920190304: 950 Clang, llvm, lld, lldb, compiler-rt and libc++ have been upgraded to 951 8.0.0. Please see the 20141231 entry below for information about 952 prerequisites and upgrading, if you are not already using clang 3.5.0 953 or higher. 954 95520190226: 956 geom_uzip(4) depends on the new module xz. If geom_uzip is statically 957 compiled into your custom kernel, add 'device xz' statement to the 958 kernel config. 959 96020190219: 961 drm and drm2 have been removed from the tree. Please see 962 https://wiki.freebsd.org/Graphics for the latest information on 963 migrating to the drm ports. 964 96520190131: 966 Iflib is no longer unconditionally compiled into the kernel. Drivers 967 using iflib and statically compiled into the kernel, now require 968 the 'device iflib' config option. For the same drivers loaded as 969 modules on kernels not having 'device iflib', the iflib.ko module 970 is loaded automatically. 971 97220190125: 973 The IEEE80211_AMPDU_AGE and AH_SUPPORT_AR5416 kernel configuration 974 options no longer exist since r343219 and r343427 respectively; 975 nothing uses them, so they should be just removed from custom 976 kernel config files. 977 97820181230: 979 r342635 changes the way efibootmgr(8) works by requiring users to add 980 the -b (bootnum) parameter for commands where the bootnum was previously 981 specified with each option. For example 'efibootmgr -B 0001' is now 982 'efibootmgr -B -b 0001'. 983 98420181220: 985 r342286 modifies the NFSv4 server so that it obeys vfs.nfsd.nfs_privport 986 in the same as it is applied to NFSv2 and 3. This implies that NFSv4 987 servers that have vfs.nfsd.nfs_privport set will only allow mounts 988 from clients using a reserved port. Since both the FreeBSD and Linux 989 NFSv4 clients use reserved ports by default, this should not affect 990 most NFSv4 mounts. 991 99220181219: 993 The XLP config has been removed. We can't support 64-bit atomics in this 994 kernel because it is running in 32-bit mode. XLP users must transition 995 to running a 64-bit kernel (XLP64 or XLPN32). 996 997 The mips GXEMUL support has been removed from FreeBSD. MALTA* + qemu is 998 the preferred emulator today and we don't need two different ones. 999 1000 The old sibyte / swarm / Broadcom BCM1250 support has been 1001 removed from the mips port. 1002 100320181211: 1004 Clang, llvm, lld, lldb, compiler-rt and libc++ have been upgraded to 1005 7.0.1. Please see the 20141231 entry below for information about 1006 prerequisites and upgrading, if you are not already using clang 3.5.0 1007 or higher. 1008 100920181211: 1010 Remove the timed and netdate programs from the base tree. Setting 1011 the time with these daemons has been obsolete for over a decade. 1012 101320181126: 1014 On amd64, arm64 and armv7 (architectures that install LLVM's ld.lld 1015 linker as /usr/bin/ld) GNU ld is no longer installed as ld.bfd, as 1016 it produces broken binaries when ifuncs are in use. Users needing 1017 GNU ld should install the binutils port or package. 1018 101920181123: 1020 The BSD crtbegin and crtend code has been enabled by default. It has 1021 had extensive testing on amd64, arm64, and i386. It can be disabled 1022 by building a world with -DWITHOUT_BSD_CRTBEGIN. 1023 102420181115: 1025 The set of CTM commands (ctm, ctm_smail, ctm_rmail, ctm_dequeue) 1026 has been converted to a port (misc/ctm) and will be removed from 1027 FreeBSD-13. It is available as a package (ctm) for all supported 1028 FreeBSD versions. 1029 103020181110: 1031 The default newsyslog.conf(5) file has been changed to only include 1032 files in /etc/newsyslog.conf.d/ and /usr/local/etc/newsyslog.conf.d/ if 1033 the filenames end in '.conf' and do not begin with a '.'. 1034 1035 You should check the configuration files in these two directories match 1036 this naming convention. You can verify which configuration files are 1037 being included using the command: 1038 $ newsyslog -Nrv 1039 104020181015: 1041 Ports for the DRM modules have been simplified. Now, amd64 users should 1042 just install the drm-kmod port. All others should install 1043 drm-legacy-kmod. 1044 1045 Graphics hardware that's newer than about 2010 usually works with 1046 drm-kmod. For hardware older than 2013, however, some users will need 1047 to use drm-legacy-kmod if drm-kmod doesn't work for them. Hardware older 1048 than 2008 usually only works in drm-legacy-kmod. The graphics team can 1049 only commit to hardware made since 2013 due to the complexity of the 1050 market and difficulty to test all the older cards effectively. If you 1051 have hardware supported by drm-kmod, you are strongly encouraged to use 1052 that as you will get better support. 1053 1054 Other than KPI chasing, drm-legacy-kmod will not be updated. As outlined 1055 elsewhere, the drm and drm2 modules will be eliminated from the src base 1056 soon (with a limited exception for arm). Please update to the package 1057 asap and report any issues to [email protected]. 1058 1059 Generally, anybody using the drm*-kmod packages should add 1060 WITHOUT_DRM_MODULE=t and WITHOUT_DRM2_MODULE=t to avoid nasty 1061 cross-threading surprises, especially with automatic driver 1062 loading from X11 startup. These will become the defaults in 13-current 1063 shortly. 1064 106520181012: 1066 The ixlv(4) driver has been renamed to iavf(4). As a consequence, 1067 custom kernel and module loading configuration files must be updated 1068 accordingly. Moreover, interfaces previous presented as ixlvN to the 1069 system are now exposed as iavfN and network configuration files must 1070 be adjusted as necessary. 1071 107220181009: 1073 OpenSSL has been updated to version 1.1.1. This update included 1074 additional various API changes throughout the base system. It is 1075 important to rebuild third-party software after upgrading. The value 1076 of __FreeBSD_version has been bumped accordingly. 1077 107820181006: 1079 The legacy DRM modules and drivers have now been added to the loader's 1080 module blacklist, in favor of loading them with kld_list in rc.conf(5). 1081 The module blacklist may be overridden with the loader.conf(5) 1082 'module_blacklist' variable, but loading them via rc.conf(5) is strongly 1083 encouraged. 1084 108520181002: 1086 The cam(4) based nda(4) driver will be used over nvd(4) by default on 1087 powerpc64. You may set 'options NVME_USE_NVD=1' in your kernel conf or 1088 loader tunable 'hw.nvme.use_nvd=1' if you wish to use the existing 1089 driver. Make sure to edit /boot/etc/kboot.conf and fstab to use the 1090 nda device name. 1091 109220180913: 1093 Reproducible build mode is now on by default, in preparation for 1094 FreeBSD 12.0. This eliminates build metadata such as the user, 1095 host, and time from the kernel (and uname), unless the working tree 1096 corresponds to a modified checkout from a version control system. 1097 The previous behavior can be obtained by setting the /etc/src.conf 1098 knob WITHOUT_REPRODUCIBLE_BUILD. 1099 110020180826: 1101 The Yarrow CSPRNG has been removed from the kernel as it has not been 1102 supported by its designers since at least 2003. Fortuna has been the 1103 default since FreeBSD-11. 1104 110520180822: 1106 devctl freeze/thaw have gone into the tree, the rc scripts have been 1107 updated to use them and devmatch has been changed. You should update 1108 kernel, userland and rc scripts all at the same time. 1109 111020180818: 1111 The default interpreter has been switched from 4th to Lua. 1112 LOADER_DEFAULT_INTERP, documented in build(7), will override the default 1113 interpreter. If you have custom FORTH code you will need to set 1114 LOADER_DEFAULT_INTERP=4th (valid values are 4th, lua or simp) in 1115 src.conf for the build. This will create default hard links between 1116 loader and loader_4th instead of loader and loader_lua, the new default. 1117 If you are using UEFI it will create the proper hard link to loader.efi. 1118 1119 bhyve uses userboot.so. It remains 4th-only until some issues are solved 1120 regarding coexisting with multiple versions of FreeBSD are resolved. 1121 112220180815: 1123 ls(1) now respects the COLORTERM environment variable used in other 1124 systems and software to indicate that a colored terminal is both 1125 supported and desired. If ls(1) is suddenly emitting colors, they may 1126 be disabled again by either removing the unwanted COLORTERM from your 1127 environment, or using `ls --color=never`. The ls(1) specific CLICOLOR 1128 may not be observed in a future release. 1129 113020180808: 1131 The default pager for most commands has been changed to "less". To 1132 restore the old behavior, set PAGER="more" and MANPAGER="more -s" in 1133 your environment. 1134 113520180731: 1136 The jedec_ts(4) driver has been removed. A superset of its functionality 1137 is available in the jedec_dimm(4) driver, and the manpage for that 1138 driver includes migration instructions. If you have "device jedec_ts" 1139 in your kernel configuration file, it must be removed. 1140 114120180730: 1142 amd64/GENERIC now has EFI runtime services, EFIRT, enabled by default. 1143 This should have no effect if the kernel is booted via BIOS/legacy boot. 1144 EFIRT may be disabled via a loader tunable, efi.rt.disabled, if a system 1145 has a buggy firmware that prevents a successful boot due to use of 1146 runtime services. 1147 114820180727: 1149 Atmel AT91RM9200 and AT91SAM9, Cavium CNS 11xx and XScale 1150 support has been removed from the tree. These ports were 1151 obsolete and/or known to be broken for many years. 1152 115320180723: 1154 loader.efi has been augmented to participate more fully in the 1155 UEFI boot manager protocol. loader.efi will now look at the 1156 BootXXXX environment variable to determine if a specific kernel 1157 or root partition was specified. XXXX is derived from BootCurrent. 1158 efibootmgr(8) manages these standard UEFI variables. 1159 116020180720: 1161 zfsloader's functionality has now been folded into loader. 1162 zfsloader is no longer necessary once you've updated your 1163 boot blocks. For a transition period, we will install a 1164 hardlink for zfsloader to loader to allow a smooth transition 1165 until the boot blocks can be updated (hard link because old 1166 zfs boot blocks don't understand symlinks). 1167 116820180719: 1169 ARM64 now have efifb support, if you want to have serial console 1170 on your arm64 board when an screen is connected and the bootloader 1171 setup a frame buffer for us to use, just add : 1172 boot_serial=YES 1173 boot_multicons=YES 1174 in /boot/loader.conf 1175 For Raspberry Pi 3 (RPI) users, this is needed even if you don't have 1176 an screen connected as the firmware will setup a frame buffer are that 1177 u-boot will expose as an EFI frame buffer. 1178 117920180719: 1180 New uid:gid added, ntpd:ntpd (123:123). Be sure to run mergemaster 1181 or take steps to update /etc/passwd before doing installworld on 1182 existing systems. Do not skip the "mergemaster -Fp" step before 1183 installworld, as described in the update procedures near the bottom 1184 of this document. Also, rc.d/ntpd now starts ntpd(8) as user ntpd 1185 if the new mac_ntpd(4) policy is available, unless ntpd_flags or 1186 the ntp config file contain options that change file/dir locations. 1187 When such options (e.g., "statsdir" or "crypto") are used, ntpd can 1188 still be run as non-root by setting ntpd_user=ntpd in rc.conf, after 1189 taking steps to ensure that all required files/dirs are accessible 1190 by the ntpd user. 1191 119220180717: 1193 Big endian arm support has been removed. 1194 119520180711: 1196 The static environment setup in kernel configs is no longer mutually 1197 exclusive with the loader(8) environment by default. In order to 1198 restore the previous default behavior of disabling the loader(8) 1199 environment if a static environment is present, you must specify 1200 loader_env.disabled=1 in the static environment. 1201 120220180705: 1203 The ABI of syscalls used by management tools like sockstat and 1204 netstat has been broken to allow 32-bit binaries to work on 1205 64-bit kernels without modification. These programs will need 1206 to match the kernel in order to function. External programs may 1207 require minor modifications to accommodate a change of type in 1208 structures from pointers to 64-bit virtual addresses. 1209 121020180702: 1211 On i386 and amd64 atomics are now inlined. Out of tree modules using 1212 atomics will need to be rebuilt. 1213 121420180701: 1215 The '%I' format in the kern.corefile sysctl limits the number of 1216 core files that a process can generate to the number stored in the 1217 debug.ncores sysctl. The '%I' format is replaced by the single digit 1218 index. Previously, if all indexes were taken the kernel would overwrite 1219 only a core file with the highest index in a filename. 1220 Currently the system will create a new core file if there is a free 1221 index or if all slots are taken it will overwrite the oldest one. 1222 122320180630: 1224 Clang, llvm, lld, lldb, compiler-rt and libc++ have been upgraded to 1225 6.0.1. Please see the 20141231 entry below for information about 1226 prerequisites and upgrading, if you are not already using clang 3.5.0 1227 or higher. 1228 122920180628: 1230 r335753 introduced a new quoting method. However, etc/devd/devmatch.conf 1231 needed to be changed to work with it. This change was made with r335763 1232 and requires a mergemaster / etcupdate / etc to update the installed 1233 file. 1234 123520180612: 1236 r334930 changed the interface between the NFS modules, so they all 1237 need to be rebuilt. r335018 did a __FreeBSD_version bump for this. 1238 123920180530: 1240 As of r334391 lld is the default amd64 system linker; it is installed 1241 as /usr/bin/ld. Kernel build workarounds (see 20180510 entry) are no 1242 longer necessary. 1243 124420180530: 1245 The kernel / userland interface for devinfo changed, so you'll 1246 need a new kernel and userland as a pair for it to work (rebuilding 1247 lib/libdevinfo is all that's required). devinfo and devmatch will 1248 not work, but everything else will when there's a mismatch. 1249 125020180523: 1251 The on-disk format for hwpmc callchain records has changed to include 1252 threadid corresponding to a given record. This changes the field offsets 1253 and thus requires that libpmcstat be rebuilt before using a kernel 1254 later than r334108. 1255 125620180517: 1257 The vxge(4) driver has been removed. This driver was introduced into 1258 HEAD one week before the Exar left the Ethernet market and is not 1259 known to be used. If you have device vxge in your kernel config file 1260 it must be removed. 1261 126220180510: 1263 The amd64 kernel now requires a ld that supports ifunc to produce a 1264 working kernel, either lld or a newer binutils. lld is built by default 1265 on amd64, and the 'buildkernel' target uses it automatically. However, 1266 it is not the default linker, so building the kernel the traditional 1267 way requires LD=ld.lld on the command line (or LD=/usr/local/bin/ld for 1268 binutils port/package). lld will soon be default, and this requirement 1269 will go away. 1270 1271 NOTE: As of r334391 lld is the default system linker on amd64, and no 1272 workaround is necessary. 1273 127420180508: 1275 The nxge(4) driver has been removed. This driver was for PCI-X 10g 1276 cards made by s2io/Neterion. The company was acquired by Exar and 1277 no longer sells or supports Ethernet products. If you have device 1278 nxge in your kernel config file it must be removed. 1279 128020180504: 1281 The tz database (tzdb) has been updated to 2018e. This version more 1282 correctly models time stamps in time zones with negative DST such as 1283 Europe/Dublin (from 1971 on), Europe/Prague (1946/7), and 1284 Africa/Windhoek (1994/2017). This does not affect the UT offsets, only 1285 time zone abbreviations and the tm_isdst flag. 1286 128720180502: 1288 The ixgb(4) driver has been removed. This driver was for an early and 1289 uncommon legacy PCI 10GbE for a single ASIC, Intel 82597EX. Intel 1290 quickly shifted to the long lived ixgbe family. If you have device 1291 ixgb in your kernel config file it must be removed. 1292 129320180501: 1294 The lmc(4) driver has been removed. This was a WAN interface 1295 card that was already reportedly rare in 2003, and had an ambiguous 1296 license. If you have device lmc in your kernel config file it must 1297 be removed. 1298 129920180413: 1300 Support for Arcnet networks has been removed. If you have device 1301 arcnet or device cm in your kernel config file they must be 1302 removed. 1303 130420180411: 1305 Support for FDDI networks has been removed. If you have device 1306 fddi or device fpa in your kernel config file they must be 1307 removed. 1308 130920180406: 1310 In addition to supporting RFC 3164 formatted messages, the 1311 syslogd(8) service is now capable of parsing RFC 5424 formatted 1312 log messages. The main benefit of using RFC 5424 is that clients 1313 may now send log messages with timestamps containing year numbers, 1314 microseconds and time zone offsets. 1315 1316 Similarly, the syslog(3) C library function has been altered to 1317 send RFC 5424 formatted messages to the local system logging 1318 daemon. On systems using syslogd(8), this change should have no 1319 negative impact, as long as syslogd(8) and the C library are 1320 updated at the same time. On systems using a different system 1321 logging daemon, it may be necessary to make configuration 1322 adjustments, depending on the software used. 1323 1324 When using syslog-ng, add the 'syslog-protocol' flag to local 1325 input sources to enable parsing of RFC 5424 formatted messages: 1326 1327 source src { 1328 unix-dgram("/var/run/log" flags(syslog-protocol)); 1329 } 1330 1331 When using rsyslog, disable the 'SysSock.UseSpecialParser' option 1332 of the 'imuxsock' module to let messages be processed by the 1333 regular RFC 3164/5424 parsing pipeline: 1334 1335 module(load="imuxsock" SysSock.UseSpecialParser="off") 1336 1337 Do note that these changes only affect communication between local 1338 applications and syslogd(8). The format that syslogd(8) uses to 1339 store messages on disk or forward messages to other systems 1340 remains unchanged. syslogd(8) still uses RFC 3164 for these 1341 purposes. Options to customize this behaviour will be added in the 1342 future. Utilities that process log files stored in /var/log are 1343 thus expected to continue to function as before. 1344 1345 __FreeBSD_version has been incremented to 1200061 to denote this 1346 change. 1347 134820180328: 1349 Support for token ring networks has been removed. If you 1350 have "device token" in your kernel config you should remove 1351 it. No device drivers supported token ring. 1352 135320180323: 1354 makefs was modified to be able to tag ISO9660 El Torito boot catalog 1355 entries as EFI instead of overloading the i386 tag as done previously. 1356 The amd64 mkisoimages.sh script used to build amd64 ISO images for 1357 release was updated to use this. This may mean that makefs must be 1358 updated before "make cdrom" can be run in the release directory. This 1359 should be as simple as: 1360 1361 $ cd $SRCDIR/usr.sbin/makefs 1362 $ make depend all install 1363 136420180212: 1365 FreeBSD boot loader enhanced with Lua scripting. It's purely opt-in for 1366 now by building WITH_LOADER_LUA and WITHOUT_FORTH in /etc/src.conf. 1367 Co-existence for the transition period will come shortly. Booting is a 1368 complex environment and test coverage for Lua-enabled loaders has been 1369 thin, so it would be prudent to assume it might not work and make 1370 provisions for backup boot methods. 1371 137220180211: 1373 devmatch functionality has been turned on in devd. It will automatically 1374 load drivers for unattached devices. This may cause unexpected drivers 1375 to be loaded. Please report any problems to current@ and 1376 [email protected]. 1377 137820180114: 1379 Clang, llvm, lld, lldb, compiler-rt and libc++ have been upgraded to 1380 6.0.0. Please see the 20141231 entry below for information about 1381 prerequisites and upgrading, if you are not already using clang 3.5.0 1382 or higher. 1383 138420180110: 1385 LLVM's lld linker is now used as the FreeBSD/amd64 bootstrap linker. 1386 This means it is used to link the kernel and userland libraries and 1387 executables, but is not yet installed as /usr/bin/ld by default. 1388 1389 To revert to ld.bfd as the bootstrap linker, in /etc/src.conf set 1390 WITHOUT_LLD_BOOTSTRAP=yes 1391 139220180110: 1393 On i386, pmtimer has been removed. Its functionality has been folded 1394 into apm. It was a no-op on ACPI in current for a while now (but was 1395 still needed on i386 in FreeBSD 11 and earlier). Users may need to 1396 remove it from kernel config files. 1397 139820180104: 1399 The use of RSS hash from the network card aka flowid has been 1400 disabled by default for lagg(4) as it's currently incompatible with 1401 the lacp and loadbalance protocols. 1402 1403 This can be re-enabled by setting the following in loader.conf: 1404 net.link.lagg.default_use_flowid="1" 1405 140620180102: 1407 The SW_WATCHDOG option is no longer necessary to enable the 1408 hardclock-based software watchdog if no hardware watchdog is 1409 configured. As before, SW_WATCHDOG will cause the software 1410 watchdog to be enabled even if a hardware watchdog is configured. 1411 141220171215: 1413 r326887 fixes the issue described in the 20171214 UPDATING entry. 1414 r326888 flips the switch back to building GELI support always. 1415 141620171214: 1417 r362593 broke ZFS + GELI support for reasons unknown. However, 1418 it also broke ZFS support generally, so GELI has been turned off 1419 by default as the lesser evil in r326857. If you boot off ZFS and/or 1420 GELI, it might not be a good time to update. 1421 142220171125: 1423 PowerPC users must update loader(8) by rebuilding world before 1424 installing a new kernel, as the protocol connecting them has 1425 changed. Without the update, loader metadata will not be passed 1426 successfully to the kernel and users will have to enter their 1427 root partition at the kernel mountroot prompt to continue booting. 1428 Newer versions of loader can boot old kernels without issue. 1429 143020171110: 1431 The LOADER_FIREWIRE_SUPPORT build variable has been renamed to 1432 WITH/OUT_LOADER_FIREWIRE. LOADER_{NO_,}GELI_SUPPORT has been renamed 1433 to WITH/OUT_LOADER_GELI. 1434 143520171106: 1436 The naive and non-compliant support of posix_fallocate(2) in ZFS 1437 has been removed as of r325320. The system call now returns EINVAL 1438 when used on a ZFS file. Although the new behavior complies with the 1439 standard, some consumers are not prepared to cope with it. 1440 One known victim is lld prior to r325420. 1441 144220171102: 1443 Building in a FreeBSD src checkout will automatically create object 1444 directories now rather than store files in the current directory if 1445 'make obj' was not ran. Calling 'make obj' is no longer necessary. 1446 This feature can be disabled by setting WITHOUT_AUTO_OBJ=yes in 1447 /etc/src-env.conf (not /etc/src.conf), or passing the option in the 1448 environment. 1449 145020171101: 1451 The default MAKEOBJDIR has changed from /usr/obj/<srcdir> for native 1452 builds, and /usr/obj/<arch>/<srcdir> for cross-builds, to a unified 1453 /usr/obj/<srcdir>/<arch>. This behavior can be changed to the old 1454 format by setting WITHOUT_UNIFIED_OBJDIR=yes in /etc/src-env.conf, 1455 the environment, or with -DWITHOUT_UNIFIED_OBJDIR when building. 1456 The UNIFIED_OBJDIR option is a transitional feature that will be 1457 removed for 12.0 release; please migrate to the new format for any 1458 tools by looking up the OBJDIR used by 'make -V .OBJDIR' means rather 1459 than hardcoding paths. 1460 146120171028: 1462 The native-xtools target no longer installs the files by default to the 1463 OBJDIR. Use the native-xtools-install target with a DESTDIR to install 1464 to ${DESTDIR}/${NXTP} where NXTP defaults to /nxb-bin. 1465 146620171021: 1467 As part of the boot loader infrastructure cleanup, LOADER_*_SUPPORT 1468 options are changing from controlling the build if defined / undefined 1469 to controlling the build with explicit 'yes' or 'no' values. They will 1470 shift to WITH/WITHOUT options to match other options in the system. 1471 147220171010: 1473 libstand has turned into a private library for sys/boot use only. 1474 It is no longer supported as a public interface outside of sys/boot. 1475 147620171005: 1477 The arm port has split armv6 into armv6 and armv7. armv7 is now 1478 a valid TARGET_ARCH/MACHINE_ARCH setting. If you have an armv7 system 1479 and are running a kernel from before r324363, you will need to add 1480 MACHINE_ARCH=armv7 to 'make buildworld' to do a native build. 1481 148220171003: 1483 When building multiple kernels using KERNCONF, non-existent KERNCONF 1484 files will produce an error and buildkernel will fail. Previously 1485 missing KERNCONF files silently failed giving no indication as to 1486 why, only to subsequently discover during installkernel that the 1487 desired kernel was never built in the first place. 1488 148920170912: 1490 The default serial number format for CTL LUNs has changed. This will 1491 affect users who use /dev/diskid/* device nodes, or whose FibreChannel 1492 or iSCSI clients care about their LUNs' serial numbers. Users who 1493 require serial number stability should hardcode serial numbers in 1494 /etc/ctl.conf . 1495 149620170912: 1497 For 32-bit arm compiled for hard-float support, soft-floating point 1498 binaries now always get their shared libraries from 1499 LD_SOFT_LIBRARY_PATH (in the past, this was only used if 1500 /usr/libsoft also existed). Only users with a hard-float ld.so, but 1501 soft-float everything else should be affected. 1502 150320170826: 1504 The geli password typed at boot is now hidden. To restore the previous 1505 behavior, see geli(8) for configuration options. 1506 150720170825: 1508 Move PMTUD blackhole counters to TCPSTATS and remove them from bare 1509 sysctl values. Minor nit, but requires a rebuild of both world/kernel 1510 to complete. 1511 151220170814: 1513 "make check" behavior (made in ^/head@r295380) has been changed to 1514 execute from a limited sandbox, as opposed to executing from 1515 ${TESTSDIR}. 1516 1517 Behavioral changes: 1518 - The "beforecheck" and "aftercheck" targets are now specified. 1519 - ${CHECKDIR} (added in commit noted above) has been removed. 1520 - Legacy behavior can be enabled by setting 1521 WITHOUT_MAKE_CHECK_USE_SANDBOX in src.conf(5) or the environment. 1522 1523 If the limited sandbox mode is enabled, "make check" will execute 1524 "make distribution", then install, execute the tests, and clean up the 1525 sandbox if successful. 1526 1527 The "make distribution" and "make install" targets are typically run as 1528 root to set appropriate permissions and ownership at installation time. 1529 The end-user should set "WITH_INSTALL_AS_USER" in src.conf(5) or the 1530 environment if executing "make check" with limited sandbox mode using 1531 an unprivileged user. 1532 153320170808: 1534 Since the switch to GPT disk labels, fsck for UFS/FFS has been 1535 unable to automatically find alternate superblocks. As of r322297, 1536 the information needed to find alternate superblocks has been 1537 moved to the end of the area reserved for the boot block. 1538 Filesystems created with a newfs of this vintage or later 1539 will create the recovery information. If you have a filesystem 1540 created prior to this change and wish to have a recovery block 1541 created for your filesystem, you can do so by running fsck in 1542 foreground mode (i.e., do not use the -p or -y options). As it 1543 starts, fsck will ask ``SAVE DATA TO FIND ALTERNATE SUPERBLOCKS'' 1544 to which you should answer yes. 1545 154620170728: 1547 As of r321665, an NFSv4 server configuration that services 1548 Kerberos mounts or clients that do not support the uid/gid in 1549 owner/owner_group string capability, must explicitly enable 1550 the nfsuserd daemon by adding nfsuserd_enable="YES" to the 1551 machine's /etc/rc.conf file. 1552 155320170722: 1554 Clang, llvm, lldb, compiler-rt and libc++ have been upgraded to 5.0.0. 1555 Please see the 20141231 entry below for information about prerequisites 1556 and upgrading, if you are not already using clang 3.5.0 or higher. 1557 155820170701: 1559 WITHOUT_RCMDS is now the default. Set WITH_RCMDS if you need the 1560 r-commands (rlogin, rsh, etc.) to be built with the base system. 1561 156220170625: 1563 The FreeBSD/powerpc platform now uses a 64-bit type for time_t. This is 1564 a very major ABI incompatible change, so users of FreeBSD/powerpc must 1565 be careful when performing source upgrades. It is best to run 1566 'make installworld' from an alternate root system, either a live 1567 CD/memory stick, or a temporary root partition. Additionally, all ports 1568 must be recompiled. powerpc64 is largely unaffected, except in the case 1569 of 32-bit compatibility. All 32-bit binaries will be affected. 1570 157120170623: 1572 Forward compatibility for the "ino64" project have been committed. This 1573 will allow most new binaries to run on older kernels in a limited 1574 fashion. This prevents many of the common foot-shooting actions in the 1575 upgrade as well as the limited ability to roll back the kernel across 1576 the ino64 upgrade. Complicated use cases may not work properly, though 1577 enough simpler ones work to allow recovery in most situations. 1578 157920170620: 1580 Switch back to the BSDL dtc (Device Tree Compiler). Set WITH_GPL_DTC 1581 if you require the GPL compiler. 1582 158320170618: 1584 The internal ABI used for communication between the NFS kernel modules 1585 was changed by r320085, so __FreeBSD_version was bumped to 1586 ensure all the NFS related modules are updated together. 1587 158820170617: 1589 The ABI of struct event was changed by extending the data 1590 member to 64bit and adding ext fields. For upgrade, same 1591 precautions as for the entry 20170523 "ino64" must be 1592 followed. 1593 159420170531: 1595 The GNU roff toolchain has been removed from base. To render manpages 1596 which are not supported by mandoc(1), man(1) can fallback on GNU roff 1597 from ports (and recommends to install it). 1598 To render roff(7) documents, consider using GNU roff from ports or the 1599 heirloom doctools roff toolchain from ports via pkg install groff or 1600 via pkg install heirloom-doctools. 1601 160220170524: 1603 The ath(4) and ath_hal(4) modules now build piecemeal to allow for 1604 smaller runtime footprint builds. This is useful for embedded systems 1605 which only require one chipset support. 1606 1607 If you load it as a module, make sure this is in /boot/loader.conf: 1608 1609 if_ath_load="YES" 1610 1611 This will load the HAL, all chip/RF backends and if_ath_pci. 1612 If you have if_ath_pci in /boot/loader.conf, ensure it is after 1613 if_ath or it will not load any HAL chipset support. 1614 1615 If you want to selectively load things (eg on cheaper ARM/MIPS 1616 platforms where RAM is at a premium) you should: 1617 1618 * load ath_hal 1619 * load the chip modules in question 1620 * load ath_rate, ath_dfs 1621 * load ath_main 1622 * load if_ath_pci and/or if_ath_ahb depending upon your particular 1623 bus bind type - this is where probe/attach is done. 1624 1625 For further comments/feedback, poke adrian@ . 1626 162720170523: 1628 The "ino64" 64-bit inode project has been committed, which extends 1629 a number of types to 64 bits. Upgrading in place requires care and 1630 adherence to the documented upgrade procedure. 1631 1632 If using a custom kernel configuration ensure that the 1633 COMPAT_FREEBSD11 option is included (as during the upgrade the 1634 system will be running the ino64 kernel with the existing world). 1635 1636 For the safest in-place upgrade begin by removing previous build 1637 artifacts via "rm -rf /usr/obj/*". Then, carefully follow the full 1638 procedure documented below under the heading "To rebuild everything and 1639 install it on the current system." Specifically, a reboot is required 1640 after installing the new kernel before installing world. While an 1641 installworld normally works by accident from multiuser after rebooting 1642 the proper kernel, there are many cases where this will fail across this 1643 upgrade and installworld from single user is required. 1644 164520170424: 1646 The NATM framework including the en(4), fatm(4), hatm(4), and 1647 patm(4) devices has been removed. Consumers should plan a 1648 migration before the end-of-life date for FreeBSD 11. 1649 165020170420: 1651 GNU diff has been replaced by a BSD licensed diff. Some features of GNU 1652 diff has not been implemented, if those are needed a newer version of 1653 GNU diff is available via the diffutils package under the gdiff name. 1654 165520170413: 1656 As of r316810 for ipfilter, keep frags is no longer assumed when 1657 keep state is specified in a rule. r316810 aligns ipfilter with 1658 documentation in man pages separating keep frags from keep state. 1659 This allows keep state to be specified without forcing keep frags 1660 and allows keep frags to be specified independently of keep state. 1661 To maintain previous behaviour, also specify keep frags with 1662 keep state (as documented in ipf.conf.5). 1663 166420170407: 1665 arm64 builds now use the base system LLD 4.0.0 linker by default, 1666 instead of requiring that the aarch64-binutils port or package be 1667 installed. To continue using aarch64-binutils, set 1668 CROSS_BINUTILS_PREFIX=/usr/local/aarch64-freebsd/bin . 1669 167020170405: 1671 The UDP optimization in entry 20160818 that added the sysctl 1672 net.inet.udp.require_l2_bcast has been reverted. L2 broadcast 1673 packets will no longer be treated as L3 broadcast packets. 1674 167520170331: 1676 Binds and sends to the loopback addresses, IPv6 and IPv4, will now 1677 use any explicitly assigned loopback address available in the jail 1678 instead of using the first assigned address of the jail. 1679 168020170329: 1681 The ctl.ko module no longer implements the iSCSI target frontend: 1682 cfiscsi.ko does instead. 1683 1684 If building cfiscsi.ko as a kernel module, the module can be loaded 1685 via one of the following methods: 1686 - `cfiscsi_load="YES"` in loader.conf(5). 1687 - Add `cfiscsi` to `$kld_list` in rc.conf(5). 1688 - ctladm(8)/ctld(8), when compiled with iSCSI support 1689 (`WITH_ISCSI=yes` in src.conf(5)) 1690 1691 Please see cfiscsi(4) for more details. 1692 169320170316: 1694 The mmcsd.ko module now additionally depends on geom_flashmap.ko. 1695 Also, mmc.ko and mmcsd.ko need to be a matching pair built from the 1696 same source (previously, the dependency of mmcsd.ko on mmc.ko was 1697 missing, but mmcsd.ko now will refuse to load if it is incompatible 1698 with mmc.ko). 1699 170020170315: 1701 The syntax of ipfw(8) named states was changed to avoid ambiguity. 1702 If you have used named states in the firewall rules, you need to modify 1703 them after installworld and before rebooting. Now named states must 1704 be prefixed with colon. 1705 170620170311: 1707 The old drm (sys/dev/drm/) drivers for i915 and radeon have been 1708 removed as the userland we provide cannot use them. The KMS version 1709 (sys/dev/drm2) supports the same hardware. 1710 171120170302: 1712 Clang, llvm, lldb, compiler-rt and libc++ have been upgraded to 4.0.0. 1713 Please see the 20141231 entry below for information about prerequisites 1714 and upgrading, if you are not already using clang 3.5.0 or higher. 1715 171620170221: 1717 The code that provides support for ZFS .zfs/ directory functionality 1718 has been reimplemented. It's not possible now to create a snapshot 1719 by mkdir under .zfs/snapshot/. That should be the only user visible 1720 change. 1721 172220170216: 1723 EISA bus support has been removed. The WITH_EISA option is no longer 1724 valid. 1725 172620170215: 1727 MCA bus support has been removed. 1728 172920170127: 1730 The WITH_LLD_AS_LD / WITHOUT_LLD_AS_LD build knobs have been renamed 1731 WITH_LLD_IS_LD / WITHOUT_LLD_IS_LD, for consistency with CLANG_IS_CC. 1732 173320170112: 1734 The EM_MULTIQUEUE kernel configuration option is deprecated now that 1735 the em(4) driver conforms to iflib specifications. 1736 173720170109: 1738 The igb(4), em(4) and lem(4) ethernet drivers are now implemented via 1739 IFLIB. If you have a custom kernel configuration that excludes em(4) 1740 but you use igb(4), you need to re-add em(4) to your custom 1741 configuration. 1742 174320161217: 1744 Clang, llvm, lldb, compiler-rt and libc++ have been upgraded to 3.9.1. 1745 Please see the 20141231 entry below for information about prerequisites 1746 and upgrading, if you are not already using clang 3.5.0 or higher. 1747 174820161124: 1749 Clang, llvm, lldb, compiler-rt and libc++ have been upgraded to 3.9.0. 1750 Please see the 20141231 entry below for information about prerequisites 1751 and upgrading, if you are not already using clang 3.5.0 or higher. 1752 175320161119: 1754 The layout of the pmap structure has changed for powerpc to put the pmap 1755 statistics at the front for all CPU variations. libkvm(3) and all tools 1756 that link against it need to be recompiled. 1757 175820161030: 1759 isl(4) and cyapa(4) drivers now require a new driver, 1760 chromebook_platform(4), to work properly on Chromebook-class hardware. 1761 On other types of hardware the drivers may need to be configured using 1762 device hints. Please see the corresponding manual pages for details. 1763 176420161017: 1765 The urtwn(4) driver was merged into rtwn(4) and now consists of 1766 rtwn(4) main module + rtwn_usb(4) and rtwn_pci(4) bus-specific 1767 parts. 1768 Also, firmware for RTL8188CE was renamed due to possible name 1769 conflict (rtwnrtl8192cU(B) -> rtwnrtl8192cE(B)) 1770 177120161015: 1772 GNU rcs has been removed from base. It is available as packages: 1773 - rcs: Latest GPLv3 GNU rcs version. 1774 - rcs57: Copy of the latest version of GNU rcs (GPLv2) before it was 1775 removed from base. 1776 177720161008: 1778 Use of the cc_cdg, cc_chd, cc_hd, or cc_vegas congestion control 1779 modules now requires that the kernel configuration contain the 1780 TCP_HHOOK option. (This option is included in the GENERIC kernel.) 1781 178220161003: 1783 The WITHOUT_ELFCOPY_AS_OBJCOPY src.conf(5) knob has been retired. 1784 ELF Tool Chain's elfcopy is always installed as /usr/bin/objcopy. 1785 178620160924: 1787 Relocatable object files with the extension of .So have been renamed 1788 to use an extension of .pico instead. The purpose of this change is 1789 to avoid a name clash with shared libraries on case-insensitive file 1790 systems. On those file systems, foo.So is the same file as foo.so. 1791 179220160918: 1793 GNU rcs has been turned off by default. It can (temporarily) be built 1794 again by adding WITH_RCS knob in src.conf. 1795 Otherwise, GNU rcs is available from packages: 1796 - rcs: Latest GPLv3 GNU rcs version. 1797 - rcs57: Copy of the latest version of GNU rcs (GPLv2) from base. 1798 179920160918: 1800 The backup_uses_rcs functionality has been removed from rc.subr. 1801 180220160908: 1803 The queue(3) debugging macro, QUEUE_MACRO_DEBUG, has been split into 1804 two separate components, QUEUE_MACRO_DEBUG_TRACE and 1805 QUEUE_MACRO_DEBUG_TRASH. Define both for the original 1806 QUEUE_MACRO_DEBUG behavior. 1807 180820160824: 1809 r304787 changed some ioctl interfaces between the iSCSI userspace 1810 programs and the kernel. ctladm, ctld, iscsictl, and iscsid must be 1811 rebuilt to work with new kernels. __FreeBSD_version has been bumped 1812 to 1200005. 1813 181420160818: 1815 The UDP receive code has been updated to only treat incoming UDP 1816 packets that were addressed to an L2 broadcast address as L3 1817 broadcast packets. It is not expected that this will affect any 1818 standards-conforming UDP application. The new behaviour can be 1819 disabled by setting the sysctl net.inet.udp.require_l2_bcast to 1820 0. 1821 182220160818: 1823 Remove the openbsd_poll system call. 1824 __FreeBSD_version has been bumped because of this. 1825 182620160708: 1827 The stable/11 branch has been created from head@r302406. 1828 1829After branch N is created, entries older than the N-2 branch point are removed 1830from this file. After stable/14 is branched and current becomes FreeBSD 15, 1831entries older than stable/12 branch point will be removed from current's 1832UPDATING file. 1833 1834COMMON ITEMS: 1835 1836 General Notes 1837 ------------- 1838 Sometimes, obscure build problems are the result of environment 1839 poisoning. This can happen because the make utility reads its 1840 environment when searching for values for global variables. To run 1841 your build attempts in an "environmental clean room", prefix all make 1842 commands with 'env -i '. See the env(1) manual page for more details. 1843 Occasionally a build failure will occur with "make -j" due to a race 1844 condition. If this happens try building again without -j, and please 1845 report a bug if it happens consistently. 1846 1847 When upgrading from one major version to another it is generally best to 1848 upgrade to the latest code in the currently installed branch first, then 1849 do an upgrade to the new branch. This is the best-tested upgrade path, 1850 and has the highest probability of being successful. Please try this 1851 approach if you encounter problems with a major version upgrade. Since 1852 the stable 4.x branch point, one has generally been able to upgrade from 1853 anywhere in the most recent stable branch to head / current (or even the 1854 last couple of stable branches). See the top of this file when there's 1855 an exception. 1856 1857 The update process will emit an error on an attempt to perform a build 1858 or install from a FreeBSD version below the earliest supported version. 1859 When updating from an older version the update should be performed one 1860 major release at a time, including running `make delete-old` at each 1861 step. 1862 1863 When upgrading a live system, having a root shell around before 1864 installing anything can help undo problems. Not having a root shell 1865 around can lead to problems if pam has changed too much from your 1866 starting point to allow continued authentication after the upgrade. 1867 1868 This file should be read as a log of events. When a later event changes 1869 information of a prior event, the prior event should not be deleted. 1870 Instead, a pointer to the entry with the new information should be 1871 placed in the old entry. Readers of this file should also sanity check 1872 older entries before relying on them blindly. Authors of new entries 1873 should write them with this in mind. 1874 1875 ZFS notes 1876 --------- 1877 When upgrading the boot ZFS pool to a new version (via zpool upgrade), 1878 always follow these three steps: 1879 1880 1) recompile and reinstall the ZFS boot loader and boot block 1881 (this is part of "make buildworld" and "make installworld") 1882 1883 2) update the ZFS boot block on your boot drive (only required when 1884 doing a zpool upgrade): 1885 1886 When booting on x86 via BIOS, use the following to update the ZFS boot 1887 block on the freebsd-boot partition of a GPT partitioned drive ada0: 1888 gpart bootcode -p /boot/gptzfsboot -i $N ada0 1889 The value $N will typically be 1. For EFI booting, see EFI notes. 1890 1891 3) zpool upgrade the root pool. New bootblocks will work with old 1892 pools, but not vice versa, so they need to be updated before any 1893 zpool upgrade. 1894 1895 Non-boot pools do not need these updates. 1896 1897 EFI notes 1898 --------- 1899 1900 There are two locations the boot loader can be installed into. The 1901 current location (and the default) is \efi\freebsd\loader.efi and using 1902 efibootmgr(8) to configure it. The old location, that must be used on 1903 deficient systems that don't honor efibootmgr(8) protocols, is the 1904 fallback location of \EFI\BOOT\BOOTxxx.EFI. Generally, you will copy 1905 /boot/loader.efi to this location, but on systems installed a long time 1906 ago the ESP may be too small and /boot/boot1.efi may be needed unless 1907 the ESP has been expanded in the meantime. 1908 1909 Recent systems will have the ESP mounted on /boot/efi, but older ones 1910 may not have it mounted at all, or mounted in a different 1911 location. Older arm SD images with MBR used /boot/msdos as the 1912 mountpoint. The ESP is a MSDOS filesystem. 1913 1914 The EFI boot loader rarely needs to be updated. For ZFS booting, 1915 however, you must update loader.efi before you do 'zpool upgrade' the 1916 root zpool, otherwise the old loader.efi may reject the upgraded zpool 1917 since it does not automatically understand some new features. 1918 1919 See loader.efi(8) and uefi(8) for more details. 1920 1921 To build a kernel 1922 ----------------- 1923 If you are updating from a prior version of FreeBSD (even one just 1924 a few days old), you should follow this procedure. It is the most 1925 failsafe as it uses a /usr/obj tree with a fresh mini-buildworld, 1926 1927 make kernel-toolchain 1928 make -DALWAYS_CHECK_MAKE buildkernel KERNCONF=YOUR_KERNEL_HERE 1929 make -DALWAYS_CHECK_MAKE installkernel KERNCONF=YOUR_KERNEL_HERE 1930 1931 To test a kernel once 1932 --------------------- 1933 If you just want to boot a kernel once (because you are not sure 1934 if it works, or if you want to boot a known bad kernel to provide 1935 debugging information) run 1936 make installkernel KERNCONF=YOUR_KERNEL_HERE KODIR=/boot/testkernel 1937 nextboot -k testkernel 1938 1939 To rebuild everything and install it on the current system. 1940 ----------------------------------------------------------- 1941 # Note: sometimes if you are running current you gotta do more than 1942 # is listed here if you are upgrading from a really old current. 1943 1944 <make sure you have good level 0 dumps> 1945 make buildworld 1946 make buildkernel KERNCONF=YOUR_KERNEL_HERE 1947 make installkernel KERNCONF=YOUR_KERNEL_HERE 1948 [1] 1949 <reboot in single user> [3] 1950 etcupdate -p [5] 1951 make installworld 1952 etcupdate -B [4] 1953 make delete-old [6] 1954 <reboot> 1955 1956 To cross-install current onto a separate partition 1957 -------------------------------------------------- 1958 # In this approach we use a separate partition to hold 1959 # current's root, 'usr', and 'var' directories.

At this point in the life 1996 cycle of current, things change often and you are on your own 1997 to cope. The defaults can also change, so please read ALL of 1998 the UPDATING entries. 1999 2000 Also, if you are tracking -current, you must be subscribed to 2001 [email protected]. Make sure that before you update 2002 your sources that you have read and understood all the recent 2003 messages there. If in doubt, please track -stable which has 2004 much fewer pitfalls. 2005 2006 [1] If you have third party modules, such as vmware, you should disable 2007 them at this point so they don't crash your system on 2008 reboot. Alternatively, you should rebuild all the modules you have in 2009 your system and install them as well. If you are running -current, you 2010 should seriously consider placing all sources to all the modules for 2011 your system (or symlinks to them) in /usr/local/sys/modules so this 2012 happens automatically. If all your modules come from ports, then adding 2013 the port origin directories to PORTS_MODULES instead is also automatic 2014 and effective, eg: 2015 PORTS_MODULES+=x11/nvidia-driver 2016 2017 [3] From the bootblocks, boot -s, and then do 2018 fsck -p 2019 mount -u / 2020 mount -a 2021 sh /etc/rc.d/zfs start # mount zfs filesystem, if needed 2022 cd src # full path to source 2023 adjkerntz -i # if CMOS is wall time 2024 Also, when doing a major release upgrade, it is required that you boot 2025 into single user mode to do the installworld. 2026 2027 [4] Note: This step is non-optional. Failure to do this step 2028 can result in a significant reduction in the functionality of the 2029 system. Attempting to do it by hand is not recommended and those 2030 that pursue this avenue should read this file carefully, as well 2031 as the archives of freebsd-current and freebsd-hackers mailing lists 2032 for potential gotchas. See etcupdate(8) for more information. 2033 2034 [5] Usually this step is a no-op. However, from time to time 2035 you may need to do this if you get unknown user in the following 2036 step. 2037 2038 [6] This only deletes old files and directories. Old libraries 2039 can be deleted by "make delete-old-libs", but you have to make 2040 sure that no program is using those libraries anymore. 2041 2042 [8] The new kernel must be able to run existing binaries used by an 2043 installworld. When upgrading across major versions, the new kernel's 2044 configuration must include the correct COMPAT_FREEBSD<n> option for 2045 existing binaries (e.g. COMPAT_FREEBSD11 to run 11.x binaries). Failure 2046 to do so may leave you with a system that is hard to boot to recover. A 2047 GENERIC kernel will include suitable compatibility options to run 2048 binaries from older branches. Note that the ability to run binaries 2049 from unsupported branches is not guaranteed. 2050 2051 Make sure that you merge any new devices from GENERIC since the 2052 last time you updated your kernel config file. Options also 2053 change over time, so you may need to adjust your custom kernels 2054 for these as well. 2055 2056 [9] If CPUTYPE is defined in your /etc/make.conf, make sure to use the 2057 "?=" instead of the "=" assignment operator, so that buildworld can 2058 override the CPUTYPE if it needs to. 2059 2060 MAKEOBJDIRPREFIX must be defined in an environment variable, and 2061 not on the command line, or in /etc/make.conf. buildworld will 2062 warn if it is improperly defined. 2063FORMAT: 2064 2065This file contains a list, in reverse chronological order, of major 2066breakages in tracking -current. It is not guaranteed to be a complete 2067list of such breakages, and only contains entries since September 23, 2011. 2068If you need to see UPDATING entries from before that date, you will need 2069to fetch an UPDATING file from an older FreeBSD release. 2070 2071Copyright information: 2072 2073Copyright 1998-2009 M.
