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 1520240419: 16 Clang, llvm, lld, lldb, compiler-rt, libc++, libunwind and openmp have 17 been upgraded to 18.1.6. It is important that you run `make delete-old` 18 as described in the COMMON ITEMS section, otherwise several libc++ 19 headers that are obsolete and need to be removed can cause compilation 20 errors in C++ programs. 21 2220240415: 23 MFC e0f3dc82727f: If you have an arm64 system that uses ACPI, you will 24 need to update your loader.efi in the ESP when you update past this 25 point. Detection of ACPI was moved earlier in the binary so the scripts 26 could use it, but old binaries don't have this, so we default to 'no 27 ACPI' in this case. 28 2920240218: 30 MFC of 713db49d06de changed 'struct ieee80211vap' internals in net80211. 31 Given we do not have enough spares and the struct is allocated by 32 drivers, all wireless drivers have to be recompiled. 33 __FreeBSD_version is updated to 1400509 to track this change. 34 3520240207: 36 sendmail 8.18.1 has been imported and merged. This version enforces 37 stricter RFC compliance by default, especially with respect to line 38 endings. This may cause issues with receiving messages from 39 non-compliant MTAs; please see the first 8.18.1 release note in 40 contrib/sendmail/RELEASE_NOTES for mitigations. 41 4220240202: 43 Loader now also read configuration files listed in local_loader_conf_files. 44 Files listed here are the last ones read. And /boot/loader.conf.local was 45 moved from loader_conf_files to local_loader_conf_files leaving only 46 loader.conf and device.hints in loader_conf_files by default. 47 48 The following sequencing is applied: 49 50 1. Bootstrap: 51 /boot/defaults/loader.conf 52 53 2. Read loader_conf_files files: 54 /boot/device.hints 55 /boot/loader.conf 56 57 3. Read loader_conf_dirs files: 58 /boot/loader.conf.d/*.conf 59 60 4. And finally, rread local_loader_conf_files files: 61 /boot/loader.conf.local 62 6320240119: 64 Commit d34f4baaf138 changed the internal interface between 65 the nfscommon and nfscl modules. As such, both need to be 66 rebuilt from sources. Therefore, bump __FreeBSD_version 67 to 1400506. 68 6920231229: 70 Commit 925d9b3abac2 modified the internal API between 71 the nfscommon and nfscl modules. 72 As such, both of these modules need to be rebuilt from 73 sources. Therefore, the __FreeBSD_version has been bumped 74 to 1400503. 75 7620231224: 77 Commits acc704b36192 and b8e137d8d32d both modified the 78 internal API between the kgssapi and krpc modules. 79 As such, both of these modules need to be rebuilt from 80 sources. 81 As such, __FreeBSD_version has been bumped to 1400502. 82 8320231113: 84 The WITHOUT_LLD_IS_LD option has been removed. When LLD is enabled 85 it is always installed as /usr/bin/ld. 86 8720230924: 88 Enable splitting out pkgbase manpages into separate packages by 89 default. To disable this, set WITHOUT_MANSPLITPKG=yes in src.conf. 90 91 9220230924: 93 Move standard include files to the clibs-dev package and move clang 94 internal libraries and headers to clang and clang-dev. Upgrading systems 95 installed using pkgbase past this change involves extra steps to allow 96 for these file moves: 97 98 pkg upgrade -y FreeBSD-utilities 99 pkg upgrade -y FreeBSD-utilities-dev 100 pkg upgrade -y 101 10220230824: 103 __FreeBSD_version 1400097 after the branching stable/14 from main. 104 10520230817: 106 Serial communication (in boot loaders, kernel, and userland) has 107 been changed to default to 115200 bps, in line with common industry 108 practice and typcial firmware serial console redirection 109 configuration. 110 111 Note that the early x86 BIOS bootloader (i.e., boot0sio) does not 112 support rates above 9600 bps and is not changed. boot0sio users may 113 set BOOT_COMCONSOLE_SPEED=9600 to use 9600 for all of the boot 114 components, or use the standard boot0 and have the boot2 stage start 115 with the serial port at 115200. 116 11720230807: 118 Following the general removal of MIPS support, the ath(4) AHB bus- 119 frontend has been removed, too, and building of the PCI support is 120 integrated with the ath(4) main module again. As a result, there's 121 no longer a need for if_ath_pci_load="YES" in /boot/loader.conf or 122 "device ath_pci" in the kernel configuration. 123 12420230803: 125 MAXCPU has been increased to 1024 in the amd64 GENERIC kernel config. 126 Out-of-tree kernel modules will need to be rebuilt. 127 12820230724: 129 CAM has been mechanically updated s/u_int(64|32|16|8)_t/uint\1_t/g 130 to move to the standard uintXX_t types from the old, traditional 131 BSD u_intXX_t types. This should be a NOP, but may cause problems 132 for out of tree changes. The SIMs were not updated since most of 133 the old u_intXX_t uses weren't due to CAM interfaces. 134 13520230629: 136 The heuristic for detecting old chromebooks with an EC bug that requires 137 atkbdc driver workarounds has changed. There should be no functional 138 change, but if your old chromebook's keyboard stops working, please 139 file a PR and assign it to imp. 140 14120230623: 142 OpenSSL has been updated to version 3.0, including changes throughout 143 the base system. It is important to rebuild third-party software 144 after upgrading. 145 14620230619: 147 To enable pf rdr rules for connections initiated from the host, pf 148 filter rules can be optionally enabled for packets delivered 149 locally. This can change the behavior of rules which match packets 150 delivered to lo0. To enable this feature: 151 152 sysctl net.pf.filter_local=1 153 service pf restart 154 155 When enabled, its best to ensure that packets delivered locally are not 156 filtered, e.g. by adding a 'skip on lo' rule. 157 15820230613: 159 Improvements to libtacplus(8) mean that tacplus.conf(5) now 160 follows POSIX shell syntax rules. This may cause TACACS+ 161 authentication to fail if the shared secret contains a single 162 quote, double quote, or backslash character which isn't 163 already properly quoted or escaped. 164 16520230612: 166 Belatedly switch the default nvme block device on x86 from nvd to nda. 167 nda created nvd compatibility links by default, so this should be a 168 nop. If this causes problems for your application, set hw.nvme.use_nvd=1 169 in your loader.conf or add `options NVME_USE_NVD=1` to your kernel 170 config. To disable the nvd compatibility aliases, add 171 kern.cam.nda.nvd_compat=0 to loader.conf. The default has been nda on 172 all non-x86 platforms for some time now. If you need to fall back, 173 please email [email protected] about why. 174 175 Encrypted swap partitions need to be changed from nvd to nda if you 176 migrate, or you need to use the above to switch back to nvd. 177 17820230422: 179 Remove portsnap(8). Users are encouraged to obtain the ports tree 180 using git instead. 181 18220230420: 183 Add jobs.mk to save typing. Enables -j${JOB_MAX} and logging 184 eg. 185 make buildworld-jobs 186 runs 187 make -j${JOB_MAX} buildworld > ../buildworld.log 2>&1 188 189 where JOB_MAX is derrived from ncpus in local.sys.mk if not set in env. 190 19120230316: 192 Video related devices for some arm devices have been renamed. 193 If you have a custom kernel config and want to use hdmi output on 194 IMX6 board you need to add "device dwc_hdmi" "device imx6_hdmi" and 195 "device imx6_ipu" to it. 196 If you have a custom kernel config and want to use hdmi output on 197 TI AM335X board you need to add "device tda19988" to it. 198 If you add "device hdmi" in it you need to remove it as it doesn't 199 exist anymore. 200 20120230221: 202 Introduce new kernel options KBD_DELAY1 and KBD_DELAY2. See atkbdc(4) 203 for details. 204 20520230206: 206 sshd now defaults to having X11Forwarding disabled, following upstream. 207 Administrators who wish to enable X11Forwarding should add 208 `X11Forwarding yes` to /etc/ssh/sshd_config. 209 21020230204: 211 Since commit 75d41cb6967 Huawei 3G/4G LTE Mobile Devices do not default 212 to ECM, but NCM mode and need u3g and ucom modules loaded. See cdce(4). 213 21420230130: 215 As of commit 7c40e2d5f685, the dependency on netlink(4) has been added 216 to the linux_common(4) module. Users relying on linux_common may need 217 to complile netlink(4) module if it is not present in their kernel. 218 21920230126: 220 The WITHOUT_CXX option has been removed. C++ components in the base 221 system are now built unconditionally. 222 22320230113: 224 LinuxKPI pci.h changes may require out-of-tree drivers to be recompiled. 225 Bump _FreeBSD_version to 1400078 to be able to detect this change. 226 22720221212: 228 llvm-objump is now always installed as objdump. Previously there was 229 no /usr/bin/objdump unless the WITH_LLVM_BINUTILS knob was used. 230 231 Some LLVM objdump options have a different output format compared to 232 GNU objdump; readelf is available for inspecting ELF files, and GNU 233 objdump is available from the devel/binutils port or package. 234 23520221205: 236 dma(8) has replaced sendmail(8) as the default mta. For people willing 237 to reenable sendmail(8): 238 239 $ cp /usr/share/examples/sendmail/mailer.conf /etc/mail/mailer.conf 240 241 and add sendmail_enable="YES" to rc.conf. 242 24320221204: 244 hw.bus.disable_failed_devices has changed from 'false' to 'true' by 245 default. Now if newbus succeeds in probing a device, but fails to attach 246 the device, we'll disable the device. In the past, we'd keep retrying 247 the device on each new driver loaded. To get that behavior now, one 248 needs to use devctl to re-enable the device, and reprobe it (or set 249 the sysctl/tunable hw.bus.disable_failed_devices=false). 250 251 NOTE: This was reverted 20221205 due to unexpected compatibility issues 252 25320221122: 254 pf no longer accepts 'scrub fragment crop' or 'scrub fragment drop-ovl'. 255 These configurations are no longer automatically reinterpreted as 256 'scrub fragment reassemble'. 257 25820221121: 259 The WITHOUT_CLANG_IS_CC option has been removed. When Clang is enabled 260 it is always installed as /usr/bin/cc (and c++, cpp). 261 26220221026: 263 Some programs have been moved into separate packages. It is recommended 264 for pkgbase users to do: 265 266 pkg install FreeBSD-dhclient FreeBSD-geom FreeBSD-resolvconf \ 267 FreeBSD-devd FreeBSD-devmatch 268 269 after upgrading to restore all the component that were previously 270 installed. 271 27220221002: 273 OPIE has been removed from the base system. If needed, it can 274 be installed from ports (security/opie) or packages (opie). 275 Otherwise, make sure that your PAM policies do not reference 276 pam_opie or pam_opieaccess. 277 27820220610: 279 LinuxKPI pm.h changes require an update to the latest drm-kmod version 280 before re-compiling to avoid errors. 281 28220211230: 283 The macros provided for the manipulation of CPU sets (e.g. CPU_AND) 284 have been modified to take 2 source arguments instead of only 1. 285 Externally maintained sources that use these macros will have to 286 be adapted. The FreeBSD version has been bumped to 1400046 to 287 reflect this change. 288 28920211214: 290 A number of the kernel include files are able to be included by 291 themselves. A test has been added to buildworld to enforce this. 292 29320211209: 294 Remove mips as a recognized target. This starts the decommissioning of 295 mips support in FreeBSD. mips related items will be removed wholesale in 296 the coming days and weeks. 297 298 This broke the NO_CLEAN build for some people. Either do a clean build 299 or touch 300 lib/clang/include/llvm/Config/Targets.def 301 lib/clang/include/llvm/Config/AsmParsers.def 302 lib/clang/include/llvm/Config/Disassemblers.def 303 lib/clang/include/llvm/Config/AsmPrinters.def 304 before the build to force everything to rebuild that needs to. 305 30620211202: 307 Unbound support for RFC8375: The special-use domain 'home.arpa' is 308 by default blocked. To unblock it use a local-zone nodefault 309 statement in unbound.conf: 310 local-zone: "home.arpa." nodefault 311 312 Or use another type of local-zone to override with your choice. 313 314 The reason for this is discussed in Section 6.1 of RFC8375: 315 Because 'home.arpa.' is not globally scoped and cannot be secured 316 using DNSSEC based on the root domain's trust anchor, there is no way 317 to tell, using a standard DNS query, in which homenet scope an answer 318 belongs. Consequently, users may experience surprising results with 319 such names when roaming to different homenets. 320 32120211118: 322 Mips has been removed from universe builds. It will be removed from the 323 tree shortly. 324 32520211110: 326 Commit b8d60729deef changed the TCP congestion control framework so 327 that any of the included congestion control modules could be 328 the single module built into the kernel. Previously newreno 329 was automatically built in through direct reference. As of 330 this commit you are required to declare at least one congestion 331 control module (e.g. 'options CC_NEWRENO') and to also declare a 332 default using the CC_DEFAULT option (e.g. options CC_DEFAULT="newreno\"). 333 The GENERIC configuration includes CC_NEWRENO and defines newreno 334 as the default. If no congestion control option is built into the 335 kernel and you are including networking, the kernel compile will 336 fail. Also if no default is declared the kernel compile will fail. 337 33820211106: 339 Commit f0c9847a6c47 changed the arguments for VOP_ALLOCATE. 340 The NFS modules must be rebuilt from sources and any out 341 of tree file systems that implement their own VOP_ALLOCATE 342 may need to be modified. 343 34420211022: 345 The synchronous PPP kernel driver sppp(4) has been removed. 346 The cp(4) and ce(4) drivers are now always compiled with netgraph(4) 347 support, formerly enabled by NETGRAPH_CRONYX option. 348 34920211020: 350 sh(1) is now the default shell for the root user. To force root to use 351 the csh shell, please run the following command as root: 352 353 # chsh -s csh 354 35520211004: 356 Ncurses distribution has been split between libtinfow and libncurses 357 with libncurses.so becoming a linker (ld) script to seamlessly link 358 to libtinfow as needed. Bump _FreeBSD_version to 1400035 to reflect 359 this change. 360 36120210923: 362 As of commit 8160a0f62be6, the dummynet module no longer depends on the 363 ipfw module. Dummynet can now be used by pf as well as ipfw. As such 364 users who relied on this dependency may need to include ipfw in the 365 list of modules to load on their systems. 366 36720210922: 368 As of commit 903873ce1560, the mixer(8) utility has got a slightly 369 new syntax. Please refer to the mixer(8) manual page for more 370 information. The old mixer utility can be installed from ports: 371 audio/freebsd-13-mixer 372 37320210911: 374 As of commit 55089ef4f8bb, the global variable nfs_maxcopyrange has 375 been deleted from the nfscommon.ko. As such, nfsd.ko must be built 376 from up to date sources to avoid an undefined reference when 377 being loaded. 378 37920210817: 380 As of commit 62ca9fc1ad56 OpenSSL no longer enables kernel TLS 381 by default. Users can enable kernel TLS via the "KTLS" SSL 382 option. This can be enabled globally by using a custom 383 OpenSSL config file via OPENSSL_CONF or via an 384 application-specific configuration option for applications 385 which permit setting SSL options via SSL_CONF_cmd(3). 386 38720210811: 388 Commit 3ad1e1c1ce20 changed the internal KAPI between the NFS 389 modules. Therefore, all need to be rebuilt from sources. 390 39120210730: 392 Commit b69019c14cd8 removes pf's DIOCGETSTATESNV ioctl. 393 As of be70c7a50d32 it is no longer used by userspace, but it does mean 394 users may not be able to enumerate pf states if they update the kernel 395 past b69019c14cd8 without first updating userspace past be70c7a50d32. 396 39720210729: 398 As of commit 01ad0c007964 if_bridge member interfaces can no longer 399 change their MTU. Changing the MTU of the bridge itself will change the 400 MTU on all member interfaces instead. 401 40220210716: 403 Commit ee29e6f31111 changed the internal KAPI between the nfscommon 404 and nfsd modules. Therefore, both need to be rebuilt from sources. 405 Bump __FreeBSD_version to 1400026 for this KAPI change. 406 40720210715: 408 The 20210707 awk update brought in a change in behavior. This has 409 been corrected as of d4d252c49976. Between these dates, if you 410 installed a new awk binary, you may not be able to build a new 411 kernel because the change in behavior affected the genoffset 412 script used to build the kernel. If you did update, the fix is 413 to update your sources past the above hash and do 414 % cd usr.bin/awk 415 % make clean all 416 % sudo -E make install 417 to enable building kernels again. 418 41920210708: 420 Commit 1e0a518d6548 changed the internal KAPI between the NFS 421 modules. They all need to be rebuilt from sources. I did not 422 bump __FreeBSD_version, since it was bumped recently. 423 42420210707: 425 awk has been updated to the latest one-true-awk version 20210215. 426 This contains a number of minor bug fixes. 427 42820210624: 429 The NFSv4 client now uses the highest minor version of NFSv4 430 supported by the NFSv4 server by default instead of minor version 0, 431 for NFSv4 mounts. 432 The "minorversion" mount option may be used to override this default. 433 43420210618: 435 Bump __FreeBSD_version to 1400024 for LinuxKPI changes. 436 Most notably netdev.h can change now as the (last) dependencies 437 (mlx4/ofed) are now using struct ifnet directly, but also for PCI 438 additions and others. 439 44020210618: 441 The directory "blacklisted" under /usr/share/certs/ has been 442 renamed to "untrusted". 443 44420210611: 445 svnlite has been removed from base. Should you need svn for any reason 446 please install the svn package or port. 447 44820210611: 449 Commit e1a907a25cfa changed the internal KAPI between the krpc 450 and nfsserver. As such, both modules must be rebuilt from 451 sources. Bump __FreeBSD_version to 1400022. 452 45320210610: 454 The an(4) driver has been removed from FreeBSD. 455 45620210608: 457 The vendor/openzfs branch was renamed to vendor/openzfs/legacy to 458 start tracking OpenZFS upstream more closely. Please see 459https://lists.freebsd.org/archives/freebsd-current/2021-June/000153.html 460 for details on how to correct any errors that might result. The 461 short version is that you need to remove the old branch locally: 462 git update-ref -d refs/remotes/freebsd/vendor/openzfs 463 (assuming your upstream origin is named 'freebsd'). 464 46520210525: 466 Commits 17accc08ae15 and de102f870501 add new files to LinuxKPI 467 which break drm-kmod. In addition various other additions where 468 committed. Bump __FreeBSD_version to 1400015 to be able to 469 detect this. 470 47120210513: 472 Commit ca179c4d74f2 changed the package in which the OpenSSL 473 libraries and utilities are packaged. 474 It is recommended for pkgbase user to do: 475 pkg install -f FreeBSD-openssl 476 before pkg upgrade otherwise some dependencies might not be met 477 and pkg will stop working as libssl will not be present anymore 478 on the system. 479 48020210426: 481 Commit 875977314881 changed the internal KAPI between 482 the nfsd and nfscommon modules. As such these modules 483 need to be rebuilt from sources. 484 Without this patch in your NFSv4.1/4.2 server, enabling 485 delegations by setting vfs.nfsd.issue_delegations non-zero 486 is not recommended. 487 48820210411: 489 Commit 7763814fc9c2 changed the internal KAPI between 490 the krpc and NFS. As such, the krpc, nfscommon and 491 nfscl modules must all be rebuilt from sources. 492 Without this patch, NFSv4.1/4.2 mounts should not 493 be done with the nfscbd(8) daemon running, to avoid 494 needing a working back channel for server->client RPCs. 495 49620210330: 497 Commit 01ae8969a9ee fixed the NFSv4.1/4.2 server so that it 498 handles binding of the back channel as required by RFC5661. 499 Until this patch is in your server, avoid use of the "nconnects" 500 mount option for Linux NFSv4.1/4.2 mounts. 501 50220210225: 503 For 64-bit architectures the base system is now built with Position 504 Independent Executable (PIE) support enabled by default. It may be 505 disabled using the WITHOUT_PIE knob. A clean build is required. 506 50720210128: 508 Various LinuxKPI functionality was added which conflicts with DRM. 509 Please update your drm-kmod port to after the __FreeBSD_version 1400003 510 update. 511 51220210108: 513 PC Card attachments for all devices have been removed. In the case of 514 wi and cmx, the entire drivers were removed because they were only 515 PC Card devices. FreeBSD_version 1300134 should be used for this 516 since it was bumped so recently. 517 51820210107: 519 Transport-independent parts of HID support have been split off the USB 520 code in to separate subsystem. Kernel configs which include one of 521 ums, ukbd, uhid, atp, wsp, wmt, uaudio, ugold or ucycom drivers should 522 be updated with adding of "device hid" line. 523 52420210105: 525 ncurses installation has been modified to only keep the widechar 526 enabled version. Incremental build is broken for that change, so it 527 requires a clean build. 528 52920201223: 530 The FreeBSD project has migrated from Subversion to Git. Temporary 531 instructions can be found at 532 https://github.com/bsdimp/freebsd-git-docs/blob/main/src-cvt.md 533 and other documents in that repo. 534 53520201216: 536 The services database has been updated to cover more of the basic 537 services expected in a modern system. The database is big enough 538 that it will cause issues in mergemaster in Releases previous to 539 12.2 and 11.3, or in very old current systems from before r358154. 540 54120201215: 542 Obsolete in-tree GDB 6.1.1 has been removed. GDB (including kgdb) 543 may be installed from ports or packages. 544 54520201124: 546 ping6 has been merged into ping. It can now be called as "ping -6". 547 See ping(8) for details. 548 54920201108: 550 Default value of net.add_addr_allfibs has been changed to 0. 551 If you have multi-fib configuration and rely on existence of all 552 interface routes in every fib, you need to set the above sysctl to 1. 553 55420201030: 555 The internal pre-processor in the calendar(1) program has been 556 extended to support more C pre-processor commands (e.g. #ifdef, #else, 557 and #undef) and to detect unbalanced conditional statements. 558 Error messages have been extended to include the filename and line 559 number if processing stops to help fixing malformed data files. 560 56120201026: 562 All the data files for the calendar(1) program, except calendar.freebsd, 563 have been moved to the deskutils/calendar-data port, much like the 564 jewish calendar entries were moved to deskutils/hebcal years ago. After 565 make delete-old-files, you need to install it to retain full 566 functionality. calendar(1) will issue a reminder for files it can't 567 find. 568 56920200923: 570 LINT files are no longer generated. We now include the relevant NOTES 571 files. Note: This may cause conflicts with updating in some cases. 572 find sys -name LINT\* -delete 573 is suggested across this commit to remove the generated LINT files. 574 575 If you have tried to update with generated files there, the svn 576 command you want to un-auger the tree is 577 cd sys/amd64/conf 578 svn revert -R . 579 and then do the above find from the top level. Substitute 'amd64' 580 above with where the error message indicates a conflict. 581 58220200824: 583 OpenZFS support has been integrated. Do not upgrade root pools until 584 the loader is updated to support zstd. Furthermore, we caution against 585 'zpool upgrade' for the next few weeks. The change should be transparent 586 unless you want to use new features. 587 588 Not all "NO_CLEAN" build scenarios work across these changes. Many 589 scenarios have been tested and fixed, but rebuilding kernels without 590 rebuilding world may fail. 591 592 The ZFS cache file has moved from /boot to /etc to match the OpenZFS 593 upstream default. A fallback to /boot has been added for mountroot. 594 595 Pool auto import behavior at boot has been moved from the kernel module 596 to an explicit "zpool import -a" in one of the rc scripts enabled by 597 zfs_enable=YES. This means your non-root zpools won't auto import until 598 you upgrade your /etc/rc.d files. 599 60020200824: 601 The resume code now notifies devd with the 'kernel' system 602 rather than the old 'kern' subsystem to be consistent with 603 other use. The old notification will be created as well, but 604 will be removed prior to FreeBSD 14.0. 605 60620200821: 607 r362275 changed the internal API between the kernel RPC and the 608 NFS modules. As such, all the modules must be recompiled from 609 sources. 610 61120200817: 612 r364330 modified the internal API used between the NFS modules. 613 As such, all the NFS modules must be re-compiled from sources. 614 61520200816: 616 Clang, llvm, lld, lldb, compiler-rt, libc++, libunwind and openmp have 617 been upgraded to 11.0.0. Please see the 20141231 entry below for 618 information about prerequisites and upgrading, if you are not already 619 using clang 3.5.0 or higher. 620 62120200810: 622 r364092 modified the internal ABI used between the kernel NFS 623 modules. As such, all of these modules need to be rebuilt 624 from sources, so a version bump was done. 625 62620200807: 627 Makefile.inc has been updated to work around the issue documented in 628 20200729. It was a case where the optimization of using symbolic links 629 to point to binaries created a situation where we'd run new binaries 630 with old libraries starting midway through the installworld process. 631 63220200729: 633 r363679 has redefined some undefined behavior in regcomp(3); notably, 634 extraneous escapes of most ordinary characters will no longer be 635 accepted. An exp-run has identified all of the problems with this in 636 ports, but other non-ports software may need extra escapes removed to 637 continue to function. 638 639 Because of this change, installworld may encounter the following error 640 from rtld: Undefined symbol "regcomp@FBSD_1.6" -- It is imperative that 641 you do not halt installworld. Instead, let it run to completion (whether 642 successful or not) and run installworld once more. 643 64420200627: 645 A new implementation of bc and dc has been imported in r362681. This 646 implementation corrects non-conformant behavior of the previous bc 647 and adds GNU bc compatible options. It offers a number of extensions, 648 is much faster on large values, and has support for message catalogs 649 (a number of languages are already supported, contributions of further 650 languages welcome). The option WITHOUT_GH_BC can be used to build the 651 world with the previous versions of bc and dc. 652 65320200625: 654 r362639 changed the internal API used between the NFS kernel modules. 655 As such, they all need to be rebuilt from sources. 656 65720200613: 658 r362158 changed the arguments for VFS_CHECKEXP(). As such, any 659 out of tree file systems need to be modified and rebuilt. 660 Also, any file systems that are modules must be rebuilt. 661 66220200604: 663 read(2) of a directory fd is now rejected by default. root may 664 re-enable it for system root only on non-ZFS filesystems with the 665 security.bsd.allow_read_dir sysctl(8) MIB if 666 security.bsd.suser_enabled=1. 667 668 It may be advised to setup aliases for grep to default to `-d skip` if 669 commonly non-recursively grepping a list that includes directories and 670 the potential for the resulting stderr output is not tolerable. Example 671 aliases are now installed, commented out, in /root/.cshrc and 672 /root/.shrc. 673 67420200523: 675 Clang, llvm, lld, lldb, compiler-rt, libc++, libunwind and openmp have 676 been upgraded to 10.0.1. Please see the 20141231 entry below for 677 information about prerequisites and upgrading, if you are not already 678 using clang 3.5.0 or higher. 679 68020200512: 681 Support for obsolete compilers has been removed from the build system. 682 Clang 6 and GCC 6.4 are the minimum supported versions. 683 68420200424: 685 closefrom(2) has been moved under COMPAT12, and replaced in libc with a 686 stub that calls close_range(2). If using a custom kernel configuration, 687 you may want to ensure that the COMPAT_FREEBSD12 option is included, as 688 a slightly older -CURRENT userland and older FreeBSD userlands may not 689 be functional without closefrom(2). 690 69120200414: 692 Upstream DTS from Linux 5.6 was merged and they now have the SID 693 and THS (Secure ID controller and THermal Sensor) node present. 694 The DTB overlays have now been removed from the tree for the H3/H5 and 695 A64 SoCs and the aw_sid and aw_thermal driver have been updated to 696 deal with upstream DTS. If you are using those overlays you need to 697 remove them from loader.conf and update the DTBs on the FAT partition. 698 69920200310: 700 Clang, llvm, lld, lldb, compiler-rt, libc++, libunwind and openmp have 701 been upgraded to 10.0.0. Please see the 20141231 entry below for 702 information about prerequisites and upgrading, if you are not already 703 using clang 3.5.0 or higher. 704 70520200309: 706 The amd(8) automount daemon has been removed from the source tree. 707 As of FreeBSD 10.1 autofs(5) is the preferred tool for automounting. 708 amd is still available in the sysutils/am-utils port. 709 71020200301: 711 Removed brooktree driver (bktr.4) from the tree. 712 71320200229: 714 The WITH_GPL_DTC option has been removed. The BSD-licenced device tree 715 compiler in usr.bin/dtc is used on all architectures which use dtc, and 716 the GPL dtc is available (if needed) from the sysutils/dtc port. 717 71820200229: 719 The WITHOUT_LLVM_LIBUNWIND option has been removed. LLVM's libunwind 720 is used by all supported CPU architectures. 721 72220200229: 723 GCC 4.2.1 has been removed from the tree. The WITH_GCC, 724 WITH_GCC_BOOTSTRAP, and WITH_GNUCXX options are no longer available. 725 Users who wish to build FreeBSD with GCC must use the external toolchain 726 ports or packages. 727 72820200220: 729 ncurses has been updated to a newer version (6.2-20200215). Given the ABI 730 has changed, users will have to rebuild all the ports that are linked to 731 ncurses. 732 73320200217: 734 The size of struct vnet and the magic cookie have changed. 735 Users need to recompile libkvm and all modules using VIMAGE 736 together with their new kernel. 737 73820200212: 739 Defining the long deprecated NO_CTF, NO_DEBUG_FILES, NO_INSTALLLIB, 740 NO_MAN, NO_PROFILE, and NO_WARNS variables is now an error. Update 741 your Makefiles and scripts to define MK_<var>=no instead as required. 742 743 One exception to this is that program or library Makefiles should 744 define MAN to empty rather than setting MK_MAN=no. 745 74620200108: 747 Clang/LLVM is now the default compiler and LLD the default 748 linker for riscv64. 749 75020200107: 751 make universe no longer uses GCC 4.2.1 on any architectures. 752 Architectures not supported by in-tree Clang/LLVM require an 753 external toolchain package. 754 75520200104: 756 GCC 4.2.1 is now not built by default, as part of the GCC 4.2.1 757 retirement plan. Specifically, the GCC, GCC_BOOTSTRAP, and GNUCXX 758 options default to off for all supported CPU architectures. As a 759 short-term transition aid they may be enabled via WITH_* options. 760 GCC 4.2.1 is expected to be removed from the tree on 2020-03-31. 761 76220200102: 763 Support for armv5 has been disconnected and is being removed. The 764 machine combination MACHINE=arm MACHINE_ARCH=arm is no longer valid. 765 You must now use a MACHINE_ARCH of armv6 or armv7. The default 766 MACHINE_ARCH for MACHINE=arm is now armv7. 767 76820191226: 769 Clang/LLVM is now the default compiler for all powerpc architectures. 770 LLD is now the default linker for powerpc64. The change for powerpc64 771 also includes a change to the ELFv2 ABI, incompatible with the existing 772 ABI. 773 77420191226: 775 Kernel-loadable random(4) modules are no longer unloadable. 776 77720191222: 778 Clang, llvm, lld, lldb, compiler-rt, libc++, libunwind and openmp have 779 been upgraded to 9.0.1. Please see the 20141231 entry below for 780 information about prerequisites and upgrading, if you are not already 781 using clang 3.5.0 or higher. 782 78320191212: 784 r355677 has modified the internal interface used between the 785 NFS modules in the kernel. As such, they must all be upgraded 786 simultaneously. I will do a version bump for this. 787 78820191205: 789 The root certificates of the Mozilla CA Certificate Store have been 790 imported into the base system and can be managed with the certctl(8) 791 utility. If you have installed the security/ca_root_nss port or package 792 with the ETCSYMLINK option (the default), be advised that there may be 793 differences between those included in the port and those included in 794 base due to differences in nss branch used as well as general update 795 frequency. Note also that certctl(8) cannot manage certs in the 796 format used by the security/ca_root_nss port. 797 79820191120: 799 The amd(8) automount daemon has been disabled by default, and will be 800 removed in the future. As of FreeBSD 10.1 the autofs(5) is available 801 for automounting. 802 80320191107: 804 The nctgpio and wbwd drivers have been moved to the superio bus. 805 If you have one of these drivers in a kernel configuration, then 806 you should add device superio to it. If you use one of these drivers 807 as a module and you compile a custom set of modules, then you should 808 add superio to the set. 809 81020191021: 811 KPIs for network drivers to access interface addresses have changed. 812 Users need to recompile NIC driver modules together with kernel. 813 81420191021: 815 The net.link.tap.user_open sysctl no longer prevents user opening of 816 already created /dev/tapNN devices. Access is still controlled by 817 node permissions, just like tun devices. The net.link.tap.user_open 818 sysctl is now used only to allow users to perform devfs cloning of 819 tap devices, and the subsequent open may not succeed if the user is not 820 in the appropriate group. This sysctl may be deprecated/removed 821 completely in the future. 822 82320191009: 824 mips, powerpc, and sparc64 are no longer built as part of 825 universe / tinderbox unless MAKE_OBSOLETE_GCC is defined. If 826 not defined, mips, powerpc, and sparc64 builds will look for 827 the xtoolchain binaries and if installed use them for universe 828 builds. As llvm 9.0 becomes vetted for these architectures, they 829 will be removed from the list. 830 83120191009: 832 Clang, llvm, lld, lldb, compiler-rt, libc++, libunwind and openmp have 833 been upgraded to 9.0.0. Please see the 20141231 entry below for 834 information about prerequisites and upgrading, if you are not already 835 using clang 3.5.0 or higher. 836 83720191003: 838 The hpt27xx, hptmv, hptnr, and hptrr drivers have been removed from 839 GENERIC. They are available as modules and can be loaded by adding 840 to /boot/loader.conf hpt27xx_load="YES", hptmv_load="YES", 841 hptnr_load="YES", or hptrr_load="YES", respectively. 842 84320190913: 844 ntpd no longer by default locks its pages in memory, allowing them 845 to be paged out by the kernel. Use rlimit memlock to restore 846 historic BSD behaviour. For example, add "rlimit memlock 32" 847 to ntp.conf to lock up to 32 MB of ntpd address space in memory. 848 84920190823: 850 Several of ping6's options have been renamed for better consistency 851 with ping. If you use any of -ARWXaghmrtwx, you must update your 852 scripts. See ping6(8) for details. 853 85420190727: 855 The vfs.fusefs.sync_unmount and vfs.fusefs.init_backgrounded sysctls 856 and the "-o sync_unmount" and "-o init_backgrounded" mount options have 857 been removed from mount_fusefs(8). You can safely remove them from 858 your scripts, because they had no effect. 859 860 The vfs.fusefs.fix_broken_io, vfs.fusefs.sync_resize, 861 vfs.fusefs.refresh_size, vfs.fusefs.mmap_enable, 862 vfs.fusefs.reclaim_revoked, and vfs.fusefs.data_cache_invalidate 863 sysctls have been removed. If you felt the need to set any of them to 864 a non-default value, please tell [email protected] why. 865 86620190713: 867 Default permissions on the /var/account/acct file (and copies of it 868 rotated by periodic daily scripts) are changed from 0644 to 0640 869 because the file contains sensitive information that should not be 870 world-readable. If the /var/account directory must be created by 871 rc.d/accounting, the mode used is now 0750. Admins who use the 872 accounting feature are encouraged to change the mode of an existing 873 /var/account directory to 0750 or 0700. 874 87520190620: 876 Entropy collection and the /dev/random device are no longer optional 877 components. The "device random" option has been removed. 878 Implementations of distilling algorithms can still be made loadable 879 with "options RANDOM_LOADABLE" (e.g., random_fortuna.ko). 880 88120190612: 882 Clang, llvm, lld, lldb, compiler-rt, libc++, libunwind and openmp have 883 been upgraded to 8.0.1. Please see the 20141231 entry below for 884 information about prerequisites and upgrading, if you are not already 885 using clang 3.5.0 or higher. 886 88720190608: 888 A fix was applied to i386 kernel modules to avoid panics with 889 dpcpu or vnet. Users need to recompile i386 kernel modules 890 having pcpu or vnet sections or they will refuse to load. 891 89220190513: 893 User-wired pages now have their own counter, 894 vm.stats.vm.v_user_wire_count. The vm.max_wired sysctl was renamed 895 to vm.max_user_wired and changed from an unsigned int to an unsigned 896 long. bhyve VMs wired with the -S are now subject to the user 897 wiring limit; the vm.max_user_wired sysctl may need to be tuned to 898 avoid running into the limit. 899 90020190507: 901 The IPSEC option has been removed from GENERIC. Users requiring 902 ipsec(4) must now load the ipsec(4) kernel module. 903 90420190507: 905 The tap(4) driver has been folded into tun(4), and the module has been 906 renamed to tuntap. You should update any kld_list="if_tap" or 907 kld_list="if_tun" entries in /etc/rc.conf, if_tap_load="YES" or 908 if_tun_load="YES" entries in /boot/loader.conf to load the if_tuntap 909 module instead, and "device tap" or "device tun" entries in kernel 910 config files to select the tuntap device instead. 911 91220190418: 913 The following knobs have been added related to tradeoffs between 914 safe use of the random device and availability in the absence of 915 entropy: 916 917 kern.random.initial_seeding.bypass_before_seeding: tunable; set 918 non-zero to bypass the random device prior to seeding, or zero to 919 block random requests until the random device is initially seeded. 920 For now, set to 1 (unsafe) by default to restore pre-r346250 boot 921 availability properties. 922 923 kern.random.initial_seeding.read_random_bypassed_before_seeding: 924 read-only diagnostic sysctl that is set when bypass is enabled and 925 read_random(9) is bypassed, to enable programmatic handling of this 926 initial condition, if desired. 927 928 kern.random.initial_seeding.arc4random_bypassed_before_seeding: 929 Similar to the above, but for arc4random(9) initial seeding. 930 931 kern.random.initial_seeding.disable_bypass_warnings: tunable; set 932 non-zero to disable warnings in dmesg when the same conditions are 933 met as for the diagnostic sysctls above. Defaults to zero, i.e., 934 produce warnings in dmesg when the conditions are met. 935 93620190416: 937 The loadable random module KPI has changed; the random_infra_init() 938 routine now requires a 3rd function pointer for a bool (*)(void) 939 method that returns true if the random device is seeded (and 940 therefore unblocked). 941 94220190404: 943 r345895 reverts r320698. This implies that an nfsuserd(8) daemon 944 built from head sources between r320757 (July 6, 2017) and 945 r338192 (Aug. 22, 2018) will not work unless the "-use-udpsock" 946 is added to the command line. 947 nfsuserd daemons built from head sources that are post-r338192 are 948 not affected and should continue to work. 949 95020190320: 951 The fuse(4) module has been renamed to fusefs(4) for consistency with 952 other filesystems. You should update any kld_load="fuse" entries in 953 /etc/rc.conf, fuse_load="YES" entries in /boot/loader.conf, and 954 "options FUSE" entries in kernel config files. 955 95620190304: 957 Clang, llvm, lld, lldb, compiler-rt and libc++ have been upgraded to 958 8.0.0. Please see the 20141231 entry below for information about 959 prerequisites and upgrading, if you are not already using clang 3.5.0 960 or higher. 961 96220190226: 963 geom_uzip(4) depends on the new module xz. If geom_uzip is statically 964 compiled into your custom kernel, add 'device xz' statement to the 965 kernel config. 966 96720190219: 968 drm and drm2 have been removed from the tree. Please see 969 https://wiki.freebsd.org/Graphics for the latest information on 970 migrating to the drm ports. 971 97220190131: 973 Iflib is no longer unconditionally compiled into the kernel. Drivers 974 using iflib and statically compiled into the kernel, now require 975 the 'device iflib' config option. For the same drivers loaded as 976 modules on kernels not having 'device iflib', the iflib.ko module 977 is loaded automatically. 978 97920190125: 980 The IEEE80211_AMPDU_AGE and AH_SUPPORT_AR5416 kernel configuration 981 options no longer exist since r343219 and r343427 respectively; 982 nothing uses them, so they should be just removed from custom 983 kernel config files. 984 98520181230: 986 r342635 changes the way efibootmgr(8) works by requiring users to add 987 the -b (bootnum) parameter for commands where the bootnum was previously 988 specified with each option. For example 'efibootmgr -B 0001' is now 989 'efibootmgr -B -b 0001'. 990 99120181220: 992 r342286 modifies the NFSv4 server so that it obeys vfs.nfsd.nfs_privport 993 in the same as it is applied to NFSv2 and 3. This implies that NFSv4 994 servers that have vfs.nfsd.nfs_privport set will only allow mounts 995 from clients using a reserved port. Since both the FreeBSD and Linux 996 NFSv4 clients use reserved ports by default, this should not affect 997 most NFSv4 mounts. 998 99920181219: 1000 The XLP config has been removed. We can't support 64-bit atomics in this 1001 kernel because it is running in 32-bit mode. XLP users must transition 1002 to running a 64-bit kernel (XLP64 or XLPN32). 1003 1004 The mips GXEMUL support has been removed from FreeBSD. MALTA* + qemu is 1005 the preferred emulator today and we don't need two different ones. 1006 1007 The old sibyte / swarm / Broadcom BCM1250 support has been 1008 removed from the mips port. 1009 101020181211: 1011 Clang, llvm, lld, lldb, compiler-rt and libc++ have been upgraded to 1012 7.0.1. Please see the 20141231 entry below for information about 1013 prerequisites and upgrading, if you are not already using clang 3.5.0 1014 or higher. 1015 101620181211: 1017 Remove the timed and netdate programs from the base tree. Setting 1018 the time with these daemons has been obsolete for over a decade. 1019 102020181126: 1021 On amd64, arm64 and armv7 (architectures that install LLVM's ld.lld 1022 linker as /usr/bin/ld) GNU ld is no longer installed as ld.bfd, as 1023 it produces broken binaries when ifuncs are in use. Users needing 1024 GNU ld should install the binutils port or package. 1025 102620181123: 1027 The BSD crtbegin and crtend code has been enabled by default. It has 1028 had extensive testing on amd64, arm64, and i386. It can be disabled 1029 by building a world with -DWITHOUT_BSD_CRTBEGIN. 1030 103120181115: 1032 The set of CTM commands (ctm, ctm_smail, ctm_rmail, ctm_dequeue) 1033 has been converted to a port (misc/ctm) and will be removed from 1034 FreeBSD-13. It is available as a package (ctm) for all supported 1035 FreeBSD versions. 1036 103720181110: 1038 The default newsyslog.conf(5) file has been changed to only include 1039 files in /etc/newsyslog.conf.d/ and /usr/local/etc/newsyslog.conf.d/ if 1040 the filenames end in '.conf' and do not begin with a '.'. 1041 1042 You should check the configuration files in these two directories match 1043 this naming convention. You can verify which configuration files are 1044 being included using the command: 1045 $ newsyslog -Nrv 1046 104720181015: 1048 Ports for the DRM modules have been simplified. Now, amd64 users should 1049 just install the drm-kmod port. All others should install 1050 drm-legacy-kmod. 1051 1052 Graphics hardware that's newer than about 2010 usually works with 1053 drm-kmod. For hardware older than 2013, however, some users will need 1054 to use drm-legacy-kmod if drm-kmod doesn't work for them. Hardware older 1055 than 2008 usually only works in drm-legacy-kmod. The graphics team can 1056 only commit to hardware made since 2013 due to the complexity of the 1057 market and difficulty to test all the older cards effectively. If you 1058 have hardware supported by drm-kmod, you are strongly encouraged to use 1059 that as you will get better support. 1060 1061 Other than KPI chasing, drm-legacy-kmod will not be updated. As outlined 1062 elsewhere, the drm and drm2 modules will be eliminated from the src base 1063 soon (with a limited exception for arm). Please update to the package 1064 asap and report any issues to [email protected]. 1065 1066 Generally, anybody using the drm*-kmod packages should add 1067 WITHOUT_DRM_MODULE=t and WITHOUT_DRM2_MODULE=t to avoid nasty 1068 cross-threading surprises, especially with automatic driver 1069 loading from X11 startup. These will become the defaults in 13-current 1070 shortly. 1071 107220181012: 1073 The ixlv(4) driver has been renamed to iavf(4). As a consequence, 1074 custom kernel and module loading configuration files must be updated 1075 accordingly. Moreover, interfaces previous presented as ixlvN to the 1076 system are now exposed as iavfN and network configuration files must 1077 be adjusted as necessary. 1078 107920181009: 1080 OpenSSL has been updated to version 1.1.1. This update included 1081 additional various API changes throughout the base system. It is 1082 important to rebuild third-party software after upgrading. The value 1083 of __FreeBSD_version has been bumped accordingly. 1084 108520181006: 1086 The legacy DRM modules and drivers have now been added to the loader's 1087 module blacklist, in favor of loading them with kld_list in rc.conf(5). 1088 The module blacklist may be overridden with the loader.conf(5) 1089 'module_blacklist' variable, but loading them via rc.conf(5) is strongly 1090 encouraged. 1091 109220181002: 1093 The cam(4) based nda(4) driver will be used over nvd(4) by default on 1094 powerpc64. You may set 'options NVME_USE_NVD=1' in your kernel conf or 1095 loader tunable 'hw.nvme.use_nvd=1' if you wish to use the existing 1096 driver. Make sure to edit /boot/etc/kboot.conf and fstab to use the 1097 nda device name. 1098 109920180913: 1100 Reproducible build mode is now on by default, in preparation for 1101 FreeBSD 12.0. This eliminates build metadata such as the user, 1102 host, and time from the kernel (and uname), unless the working tree 1103 corresponds to a modified checkout from a version control system. 1104 The previous behavior can be obtained by setting the /etc/src.conf 1105 knob WITHOUT_REPRODUCIBLE_BUILD. 1106 110720180826: 1108 The Yarrow CSPRNG has been removed from the kernel as it has not been 1109 supported by its designers since at least 2003. Fortuna has been the 1110 default since FreeBSD-11. 1111 111220180822: 1113 devctl freeze/thaw have gone into the tree, the rc scripts have been 1114 updated to use them and devmatch has been changed. You should update 1115 kernel, userland and rc scripts all at the same time. 1116 111720180818: 1118 The default interpreter has been switched from 4th to Lua. 1119 LOADER_DEFAULT_INTERP, documented in build(7), will override the default 1120 interpreter. If you have custom FORTH code you will need to set 1121 LOADER_DEFAULT_INTERP=4th (valid values are 4th, lua or simp) in 1122 src.conf for the build. This will create default hard links between 1123 loader and loader_4th instead of loader and loader_lua, the new default. 1124 If you are using UEFI it will create the proper hard link to loader.efi. 1125 1126 bhyve uses userboot.so. It remains 4th-only until some issues are solved 1127 regarding coexisting with multiple versions of FreeBSD are resolved. 1128 112920180815: 1130 ls(1) now respects the COLORTERM environment variable used in other 1131 systems and software to indicate that a colored terminal is both 1132 supported and desired. If ls(1) is suddenly emitting colors, they may 1133 be disabled again by either removing the unwanted COLORTERM from your 1134 environment, or using `ls --color=never`. The ls(1) specific CLICOLOR 1135 may not be observed in a future release. 1136 113720180808: 1138 The default pager for most commands has been changed to "less". To 1139 restore the old behavior, set PAGER="more" and MANPAGER="more -s" in 1140 your environment. 1141 114220180731: 1143 The jedec_ts(4) driver has been removed. A superset of its functionality 1144 is available in the jedec_dimm(4) driver, and the manpage for that 1145 driver includes migration instructions. If you have "device jedec_ts" 1146 in your kernel configuration file, it must be removed. 1147 114820180730: 1149 amd64/GENERIC now has EFI runtime services, EFIRT, enabled by default. 1150 This should have no effect if the kernel is booted via BIOS/legacy boot. 1151 EFIRT may be disabled via a loader tunable, efi.rt.disabled, if a system 1152 has a buggy firmware that prevents a successful boot due to use of 1153 runtime services. 1154 115520180727: 1156 Atmel AT91RM9200 and AT91SAM9, Cavium CNS 11xx and XScale 1157 support has been removed from the tree. These ports were 1158 obsolete and/or known to be broken for many years. 1159 116020180723: 1161 loader.efi has been augmented to participate more fully in the 1162 UEFI boot manager protocol. loader.efi will now look at the 1163 BootXXXX environment variable to determine if a specific kernel 1164 or root partition was specified. XXXX is derived from BootCurrent. 1165 efibootmgr(8) manages these standard UEFI variables. 1166 116720180720: 1168 zfsloader's functionality has now been folded into loader. 1169 zfsloader is no longer necessary once you've updated your 1170 boot blocks. For a transition period, we will install a 1171 hardlink for zfsloader to loader to allow a smooth transition 1172 until the boot blocks can be updated (hard link because old 1173 zfs boot blocks don't understand symlinks). 1174 117520180719: 1176 ARM64 now have efifb support, if you want to have serial console 1177 on your arm64 board when an screen is connected and the bootloader 1178 setup a frame buffer for us to use, just add : 1179 boot_serial=YES 1180 boot_multicons=YES 1181 in /boot/loader.conf 1182 For Raspberry Pi 3 (RPI) users, this is needed even if you don't have 1183 an screen connected as the firmware will setup a frame buffer are that 1184 u-boot will expose as an EFI frame buffer. 1185 118620180719: 1187 New uid:gid added, ntpd:ntpd (123:123). Be sure to run mergemaster 1188 or take steps to update /etc/passwd before doing installworld on 1189 existing systems. Do not skip the "mergemaster -Fp" step before 1190 installworld, as described in the update procedures near the bottom 1191 of this document. Also, rc.d/ntpd now starts ntpd(8) as user ntpd 1192 if the new mac_ntpd(4) policy is available, unless ntpd_flags or 1193 the ntp config file contain options that change file/dir locations. 1194 When such options (e.g., "statsdir" or "crypto") are used, ntpd can 1195 still be run as non-root by setting ntpd_user=ntpd in rc.conf, after 1196 taking steps to ensure that all required files/dirs are accessible 1197 by the ntpd user. 1198 119920180717: 1200 Big endian arm support has been removed. 1201 120220180711: 1203 The static environment setup in kernel configs is no longer mutually 1204 exclusive with the loader(8) environment by default. In order to 1205 restore the previous default behavior of disabling the loader(8) 1206 environment if a static environment is present, you must specify 1207 loader_env.disabled=1 in the static environment. 1208 120920180705: 1210 The ABI of syscalls used by management tools like sockstat and 1211 netstat has been broken to allow 32-bit binaries to work on 1212 64-bit kernels without modification. These programs will need 1213 to match the kernel in order to function. External programs may 1214 require minor modifications to accommodate a change of type in 1215 structures from pointers to 64-bit virtual addresses. 1216 121720180702: 1218 On i386 and amd64 atomics are now inlined. Out of tree modules using 1219 atomics will need to be rebuilt. 1220 122120180701: 1222 The '%I' format in the kern.corefile sysctl limits the number of 1223 core files that a process can generate to the number stored in the 1224 debug.ncores sysctl. The '%I' format is replaced by the single digit 1225 index. Previously, if all indexes were taken the kernel would overwrite 1226 only a core file with the highest index in a filename. 1227 Currently the system will create a new core file if there is a free 1228 index or if all slots are taken it will overwrite the oldest one. 1229 123020180630: 1231 Clang, llvm, lld, lldb, compiler-rt and libc++ have been upgraded to 1232 6.0.1. Please see the 20141231 entry below for information about 1233 prerequisites and upgrading, if you are not already using clang 3.5.0 1234 or higher. 1235 123620180628: 1237 r335753 introduced a new quoting method. However, etc/devd/devmatch.conf 1238 needed to be changed to work with it. This change was made with r335763 1239 and requires a mergemaster / etcupdate / etc to update the installed 1240 file. 1241 124220180612: 1243 r334930 changed the interface between the NFS modules, so they all 1244 need to be rebuilt. r335018 did a __FreeBSD_version bump for this. 1245 124620180530: 1247 As of r334391 lld is the default amd64 system linker; it is installed 1248 as /usr/bin/ld. Kernel build workarounds (see 20180510 entry) are no 1249 longer necessary. 1250 125120180530: 1252 The kernel / userland interface for devinfo changed, so you'll 1253 need a new kernel and userland as a pair for it to work (rebuilding 1254 lib/libdevinfo is all that's required). devinfo and devmatch will 1255 not work, but everything else will when there's a mismatch. 1256 125720180523: 1258 The on-disk format for hwpmc callchain records has changed to include 1259 threadid corresponding to a given record. This changes the field offsets 1260 and thus requires that libpmcstat be rebuilt before using a kernel 1261 later than r334108. 1262 126320180517: 1264 The vxge(4) driver has been removed. This driver was introduced into 1265 HEAD one week before the Exar left the Ethernet market and is not 1266 known to be used. If you have device vxge in your kernel config file 1267 it must be removed. 1268 126920180510: 1270 The amd64 kernel now requires a ld that supports ifunc to produce a 1271 working kernel, either lld or a newer binutils. lld is built by default 1272 on amd64, and the 'buildkernel' target uses it automatically. However, 1273 it is not the default linker, so building the kernel the traditional 1274 way requires LD=ld.lld on the command line (or LD=/usr/local/bin/ld for 1275 binutils port/package). lld will soon be default, and this requirement 1276 will go away. 1277 1278 NOTE: As of r334391 lld is the default system linker on amd64, and no 1279 workaround is necessary. 1280 128120180508: 1282 The nxge(4) driver has been removed. This driver was for PCI-X 10g 1283 cards made by s2io/Neterion. The company was acquired by Exar and 1284 no longer sells or supports Ethernet products. If you have device 1285 nxge in your kernel config file it must be removed. 1286 128720180504: 1288 The tz database (tzdb) has been updated to 2018e. This version more 1289 correctly models time stamps in time zones with negative DST such as 1290 Europe/Dublin (from 1971 on), Europe/Prague (1946/7), and 1291 Africa/Windhoek (1994/2017). This does not affect the UT offsets, only 1292 time zone abbreviations and the tm_isdst flag. 1293 129420180502: 1295 The ixgb(4) driver has been removed. This driver was for an early and 1296 uncommon legacy PCI 10GbE for a single ASIC, Intel 82597EX. Intel 1297 quickly shifted to the long lived ixgbe family. If you have device 1298 ixgb in your kernel config file it must be removed. 1299 130020180501: 1301 The lmc(4) driver has been removed. This was a WAN interface 1302 card that was already reportedly rare in 2003, and had an ambiguous 1303 license. If you have device lmc in your kernel config file it must 1304 be removed. 1305 130620180413: 1307 Support for Arcnet networks has been removed. If you have device 1308 arcnet or device cm in your kernel config file they must be 1309 removed. 1310 131120180411: 1312 Support for FDDI networks has been removed. If you have device 1313 fddi or device fpa in your kernel config file they must be 1314 removed. 1315 131620180406: 1317 In addition to supporting RFC 3164 formatted messages, the 1318 syslogd(8) service is now capable of parsing RFC 5424 formatted 1319 log messages. The main benefit of using RFC 5424 is that clients 1320 may now send log messages with timestamps containing year numbers, 1321 microseconds and time zone offsets. 1322 1323 Similarly, the syslog(3) C library function has been altered to 1324 send RFC 5424 formatted messages to the local system logging 1325 daemon. On systems using syslogd(8), this change should have no 1326 negative impact, as long as syslogd(8) and the C library are 1327 updated at the same time. On systems using a different system 1328 logging daemon, it may be necessary to make configuration 1329 adjustments, depending on the software used. 1330 1331 When using syslog-ng, add the 'syslog-protocol' flag to local 1332 input sources to enable parsing of RFC 5424 formatted messages: 1333 1334 source src { 1335 unix-dgram("/var/run/log" flags(syslog-protocol)); 1336 } 1337 1338 When using rsyslog, disable the 'SysSock.UseSpecialParser' option 1339 of the 'imuxsock' module to let messages be processed by the 1340 regular RFC 3164/5424 parsing pipeline: 1341 1342 module(load="imuxsock" SysSock.UseSpecialParser="off") 1343 1344 Do note that these changes only affect communication between local 1345 applications and syslogd(8). The format that syslogd(8) uses to 1346 store messages on disk or forward messages to other systems 1347 remains unchanged. syslogd(8) still uses RFC 3164 for these 1348 purposes. Options to customize this behaviour will be added in the 1349 future. Utilities that process log files stored in /var/log are 1350 thus expected to continue to function as before. 1351 1352 __FreeBSD_version has been incremented to 1200061 to denote this 1353 change. 1354 135520180328: 1356 Support for token ring networks has been removed. If you 1357 have "device token" in your kernel config you should remove 1358 it. No device drivers supported token ring. 1359 136020180323: 1361 makefs was modified to be able to tag ISO9660 El Torito boot catalog 1362 entries as EFI instead of overloading the i386 tag as done previously. 1363 The amd64 mkisoimages.sh script used to build amd64 ISO images for 1364 release was updated to use this. This may mean that makefs must be 1365 updated before "make cdrom" can be run in the release directory. This 1366 should be as simple as: 1367 1368 $ cd $SRCDIR/usr.sbin/makefs 1369 $ make depend all install 1370 137120180212: 1372 FreeBSD boot loader enhanced with Lua scripting. It's purely opt-in for 1373 now by building WITH_LOADER_LUA and WITHOUT_FORTH in /etc/src.conf. 1374 Co-existence for the transition period will come shortly. Booting is a 1375 complex environment and test coverage for Lua-enabled loaders has been 1376 thin, so it would be prudent to assume it might not work and make 1377 provisions for backup boot methods. 1378 137920180211: 1380 devmatch functionality has been turned on in devd. It will automatically 1381 load drivers for unattached devices. This may cause unexpected drivers 1382 to be loaded. Please report any problems to current@ and 1383 [email protected]. 1384 138520180114: 1386 Clang, llvm, lld, lldb, compiler-rt and libc++ have been upgraded to 1387 6.0.0. Please see the 20141231 entry below for information about 1388 prerequisites and upgrading, if you are not already using clang 3.5.0 1389 or higher. 1390 139120180110: 1392 LLVM's lld linker is now used as the FreeBSD/amd64 bootstrap linker. 1393 This means it is used to link the kernel and userland libraries and 1394 executables, but is not yet installed as /usr/bin/ld by default. 1395 1396 To revert to ld.bfd as the bootstrap linker, in /etc/src.conf set 1397 WITHOUT_LLD_BOOTSTRAP=yes 1398 139920180110: 1400 On i386, pmtimer has been removed. Its functionality has been folded 1401 into apm. It was a no-op on ACPI in current for a while now (but was 1402 still needed on i386 in FreeBSD 11 and earlier). Users may need to 1403 remove it from kernel config files. 1404 140520180104: 1406 The use of RSS hash from the network card aka flowid has been 1407 disabled by default for lagg(4) as it's currently incompatible with 1408 the lacp and loadbalance protocols. 1409 1410 This can be re-enabled by setting the following in loader.conf: 1411 net.link.lagg.default_use_flowid="1" 1412 141320180102: 1414 The SW_WATCHDOG option is no longer necessary to enable the 1415 hardclock-based software watchdog if no hardware watchdog is 1416 configured. As before, SW_WATCHDOG will cause the software 1417 watchdog to be enabled even if a hardware watchdog is configured. 1418 141920171215: 1420 r326887 fixes the issue described in the 20171214 UPDATING entry. 1421 r326888 flips the switch back to building GELI support always. 1422 142320171214: 1424 r362593 broke ZFS + GELI support for reasons unknown. However, 1425 it also broke ZFS support generally, so GELI has been turned off 1426 by default as the lesser evil in r326857. If you boot off ZFS and/or 1427 GELI, it might not be a good time to update. 1428 142920171125: 1430 PowerPC users must update loader(8) by rebuilding world before 1431 installing a new kernel, as the protocol connecting them has 1432 changed. Without the update, loader metadata will not be passed 1433 successfully to the kernel and users will have to enter their 1434 root partition at the kernel mountroot prompt to continue booting. 1435 Newer versions of loader can boot old kernels without issue. 1436 143720171110: 1438 The LOADER_FIREWIRE_SUPPORT build variable has been renamed to 1439 WITH/OUT_LOADER_FIREWIRE. LOADER_{NO_,}GELI_SUPPORT has been renamed 1440 to WITH/OUT_LOADER_GELI. 1441 144220171106: 1443 The naive and non-compliant support of posix_fallocate(2) in ZFS 1444 has been removed as of r325320. The system call now returns EINVAL 1445 when used on a ZFS file. Although the new behavior complies with the 1446 standard, some consumers are not prepared to cope with it. 1447 One known victim is lld prior to r325420. 1448 144920171102: 1450 Building in a FreeBSD src checkout will automatically create object 1451 directories now rather than store files in the current directory if 1452 'make obj' was not ran. Calling 'make obj' is no longer necessary. 1453 This feature can be disabled by setting WITHOUT_AUTO_OBJ=yes in 1454 /etc/src-env.conf (not /etc/src.conf), or passing the option in the 1455 environment. 1456 145720171101: 1458 The default MAKEOBJDIR has changed from /usr/obj/<srcdir> for native 1459 builds, and /usr/obj/<arch>/<srcdir> for cross-builds, to a unified 1460 /usr/obj/<srcdir>/<arch>. This behavior can be changed to the old 1461 format by setting WITHOUT_UNIFIED_OBJDIR=yes in /etc/src-env.conf, 1462 the environment, or with -DWITHOUT_UNIFIED_OBJDIR when building. 1463 The UNIFIED_OBJDIR option is a transitional feature that will be 1464 removed for 12.0 release; please migrate to the new format for any 1465 tools by looking up the OBJDIR used by 'make -V .OBJDIR' means rather 1466 than hardcoding paths. 1467 146820171028: 1469 The native-xtools target no longer installs the files by default to the 1470 OBJDIR. Use the native-xtools-install target with a DESTDIR to install 1471 to ${DESTDIR}/${NXTP} where NXTP defaults to /nxb-bin. 1472 147320171021: 1474 As part of the boot loader infrastructure cleanup, LOADER_*_SUPPORT 1475 options are changing from controlling the build if defined / undefined 1476 to controlling the build with explicit 'yes' or 'no' values. They will 1477 shift to WITH/WITHOUT options to match other options in the system. 1478 147920171010: 1480 libstand has turned into a private library for sys/boot use only. 1481 It is no longer supported as a public interface outside of sys/boot. 1482 148320171005: 1484 The arm port has split armv6 into armv6 and armv7. armv7 is now 1485 a valid TARGET_ARCH/MACHINE_ARCH setting. If you have an armv7 system 1486 and are running a kernel from before r324363, you will need to add 1487 MACHINE_ARCH=armv7 to 'make buildworld' to do a native build. 1488 148920171003: 1490 When building multiple kernels using KERNCONF, non-existent KERNCONF 1491 files will produce an error and buildkernel will fail. Previously 1492 missing KERNCONF files silently failed giving no indication as to 1493 why, only to subsequently discover during installkernel that the 1494 desired kernel was never built in the first place. 1495 149620170912: 1497 The default serial number format for CTL LUNs has changed. This will 1498 affect users who use /dev/diskid/* device nodes, or whose FibreChannel 1499 or iSCSI clients care about their LUNs' serial numbers. Users who 1500 require serial number stability should hardcode serial numbers in 1501 /etc/ctl.conf . 1502 150320170912: 1504 For 32-bit arm compiled for hard-float support, soft-floating point 1505 binaries now always get their shared libraries from 1506 LD_SOFT_LIBRARY_PATH (in the past, this was only used if 1507 /usr/libsoft also existed). Only users with a hard-float ld.so, but 1508 soft-float everything else should be affected. 1509 151020170826: 1511 The geli password typed at boot is now hidden. To restore the previous 1512 behavior, see geli(8) for configuration options. 1513 151420170825: 1515 Move PMTUD blackhole counters to TCPSTATS and remove them from bare 1516 sysctl values. Minor nit, but requires a rebuild of both world/kernel 1517 to complete. 1518 151920170814: 1520 "make check" behavior (made in ^/head@r295380) has been changed to 1521 execute from a limited sandbox, as opposed to executing from 1522 ${TESTSDIR}. 1523 1524 Behavioral changes: 1525 - The "beforecheck" and "aftercheck" targets are now specified. 1526 - ${CHECKDIR} (added in commit noted above) has been removed. 1527 - Legacy behavior can be enabled by setting 1528 WITHOUT_MAKE_CHECK_USE_SANDBOX in src.conf(5) or the environment. 1529 1530 If the limited sandbox mode is enabled, "make check" will execute 1531 "make distribution", then install, execute the tests, and clean up the 1532 sandbox if successful. 1533 1534 The "make distribution" and "make install" targets are typically run as 1535 root to set appropriate permissions and ownership at installation time. 1536 The end-user should set "WITH_INSTALL_AS_USER" in src.conf(5) or the 1537 environment if executing "make check" with limited sandbox mode using 1538 an unprivileged user. 1539 154020170808: 1541 Since the switch to GPT disk labels, fsck for UFS/FFS has been 1542 unable to automatically find alternate superblocks. As of r322297, 1543 the information needed to find alternate superblocks has been 1544 moved to the end of the area reserved for the boot block. 1545 Filesystems created with a newfs of this vintage or later 1546 will create the recovery information. If you have a filesystem 1547 created prior to this change and wish to have a recovery block 1548 created for your filesystem, you can do so by running fsck in 1549 foreground mode (i.e., do not use the -p or -y options). As it 1550 starts, fsck will ask ``SAVE DATA TO FIND ALTERNATE SUPERBLOCKS'' 1551 to which you should answer yes. 1552 155320170728: 1554 As of r321665, an NFSv4 server configuration that services 1555 Kerberos mounts or clients that do not support the uid/gid in 1556 owner/owner_group string capability, must explicitly enable 1557 the nfsuserd daemon by adding nfsuserd_enable="YES" to the 1558 machine's /etc/rc.conf file. 1559 156020170722: 1561 Clang, llvm, lldb, compiler-rt and libc++ have been upgraded to 5.0.0. 1562 Please see the 20141231 entry below for information about prerequisites 1563 and upgrading, if you are not already using clang 3.5.0 or higher. 1564 156520170701: 1566 WITHOUT_RCMDS is now the default. Set WITH_RCMDS if you need the 1567 r-commands (rlogin, rsh, etc.) to be built with the base system. 1568 156920170625: 1570 The FreeBSD/powerpc platform now uses a 64-bit type for time_t. This is 1571 a very major ABI incompatible change, so users of FreeBSD/powerpc must 1572 be careful when performing source upgrades. It is best to run 1573 'make installworld' from an alternate root system, either a live 1574 CD/memory stick, or a temporary root partition. Additionally, all ports 1575 must be recompiled. powerpc64 is largely unaffected, except in the case 1576 of 32-bit compatibility. All 32-bit binaries will be affected. 1577 157820170623: 1579 Forward compatibility for the "ino64" project have been committed. This 1580 will allow most new binaries to run on older kernels in a limited 1581 fashion. This prevents many of the common foot-shooting actions in the 1582 upgrade as well as the limited ability to roll back the kernel across 1583 the ino64 upgrade. Complicated use cases may not work properly, though 1584 enough simpler ones work to allow recovery in most situations. 1585 158620170620: 1587 Switch back to the BSDL dtc (Device Tree Compiler). Set WITH_GPL_DTC 1588 if you require the GPL compiler. 1589 159020170618: 1591 The internal ABI used for communication between the NFS kernel modules 1592 was changed by r320085, so __FreeBSD_version was bumped to 1593 ensure all the NFS related modules are updated together. 1594 159520170617: 1596 The ABI of struct event was changed by extending the data 1597 member to 64bit and adding ext fields. For upgrade, same 1598 precautions as for the entry 20170523 "ino64" must be 1599 followed. 1600 160120170531: 1602 The GNU roff toolchain has been removed from base. To render manpages 1603 which are not supported by mandoc(1), man(1) can fallback on GNU roff 1604 from ports (and recommends to install it). 1605 To render roff(7) documents, consider using GNU roff from ports or the 1606 heirloom doctools roff toolchain from ports via pkg install groff or 1607 via pkg install heirloom-doctools. 1608 160920170524: 1610 The ath(4) and ath_hal(4) modules now build piecemeal to allow for 1611 smaller runtime footprint builds. This is useful for embedded systems 1612 which only require one chipset support. 1613 1614 If you load it as a module, make sure this is in /boot/loader.conf: 1615 1616 if_ath_load="YES" 1617 1618 This will load the HAL, all chip/RF backends and if_ath_pci. 1619 If you have if_ath_pci in /boot/loader.conf, ensure it is after 1620 if_ath or it will not load any HAL chipset support. 1621 1622 If you want to selectively load things (eg on cheaper ARM/MIPS 1623 platforms where RAM is at a premium) you should: 1624 1625 * load ath_hal 1626 * load the chip modules in question 1627 * load ath_rate, ath_dfs 1628 * load ath_main 1629 * load if_ath_pci and/or if_ath_ahb depending upon your particular 1630 bus bind type - this is where probe/attach is done. 1631 1632 For further comments/feedback, poke adrian@ . 1633 163420170523: 1635 The "ino64" 64-bit inode project has been committed, which extends 1636 a number of types to 64 bits. Upgrading in place requires care and 1637 adherence to the documented upgrade procedure. 1638 1639 If using a custom kernel configuration ensure that the 1640 COMPAT_FREEBSD11 option is included (as during the upgrade the 1641 system will be running the ino64 kernel with the existing world). 1642 1643 For the safest in-place upgrade begin by removing previous build 1644 artifacts via "rm -rf /usr/obj/*". Then, carefully follow the full 1645 procedure documented below under the heading "To rebuild everything and 1646 install it on the current system." Specifically, a reboot is required 1647 after installing the new kernel before installing world. While an 1648 installworld normally works by accident from multiuser after rebooting 1649 the proper kernel, there are many cases where this will fail across this 1650 upgrade and installworld from single user is required. 1651 165220170424: 1653 The NATM framework including the en(4), fatm(4), hatm(4), and 1654 patm(4) devices has been removed. Consumers should plan a 1655 migration before the end-of-life date for FreeBSD 11. 1656 165720170420: 1658 GNU diff has been replaced by a BSD licensed diff. Some features of GNU 1659 diff has not been implemented, if those are needed a newer version of 1660 GNU diff is available via the diffutils package under the gdiff name. 1661 166220170413: 1663 As of r316810 for ipfilter, keep frags is no longer assumed when 1664 keep state is specified in a rule. r316810 aligns ipfilter with 1665 documentation in man pages separating keep frags from keep state. 1666 This allows keep state to be specified without forcing keep frags 1667 and allows keep frags to be specified independently of keep state. 1668 To maintain previous behaviour, also specify keep frags with 1669 keep state (as documented in ipf.conf.5). 1670 167120170407: 1672 arm64 builds now use the base system LLD 4.0.0 linker by default, 1673 instead of requiring that the aarch64-binutils port or package be 1674 installed. To continue using aarch64-binutils, set 1675 CROSS_BINUTILS_PREFIX=/usr/local/aarch64-freebsd/bin . 1676 167720170405: 1678 The UDP optimization in entry 20160818 that added the sysctl 1679 net.inet.udp.require_l2_bcast has been reverted. L2 broadcast 1680 packets will no longer be treated as L3 broadcast packets. 1681 168220170331: 1683 Binds and sends to the loopback addresses, IPv6 and IPv4, will now 1684 use any explicitly assigned loopback address available in the jail 1685 instead of using the first assigned address of the jail. 1686 168720170329: 1688 The ctl.ko module no longer implements the iSCSI target frontend: 1689 cfiscsi.ko does instead. 1690 1691 If building cfiscsi.ko as a kernel module, the module can be loaded 1692 via one of the following methods: 1693 - `cfiscsi_load="YES"` in loader.conf(5). 1694 - Add `cfiscsi` to `$kld_list` in rc.conf(5). 1695 - ctladm(8)/ctld(8), when compiled with iSCSI support 1696 (`WITH_ISCSI=yes` in src.conf(5)) 1697 1698 Please see cfiscsi(4) for more details. 1699 170020170316: 1701 The mmcsd.ko module now additionally depends on geom_flashmap.ko. 1702 Also, mmc.ko and mmcsd.ko need to be a matching pair built from the 1703 same source (previously, the dependency of mmcsd.ko on mmc.ko was 1704 missing, but mmcsd.ko now will refuse to load if it is incompatible 1705 with mmc.ko). 1706 170720170315: 1708 The syntax of ipfw(8) named states was changed to avoid ambiguity. 1709 If you have used named states in the firewall rules, you need to modify 1710 them after installworld and before rebooting. Now named states must 1711 be prefixed with colon. 1712 171320170311: 1714 The old drm (sys/dev/drm/) drivers for i915 and radeon have been 1715 removed as the userland we provide cannot use them. The KMS version 1716 (sys/dev/drm2) supports the same hardware. 1717 171820170302: 1719 Clang, llvm, lldb, compiler-rt and libc++ have been upgraded to 4.0.0. 1720 Please see the 20141231 entry below for information about prerequisites 1721 and upgrading, if you are not already using clang 3.5.0 or higher. 1722 172320170221: 1724 The code that provides support for ZFS .zfs/ directory functionality 1725 has been reimplemented. It's not possible now to create a snapshot 1726 by mkdir under .zfs/snapshot/. That should be the only user visible 1727 change. 1728 172920170216: 1730 EISA bus support has been removed. The WITH_EISA option is no longer 1731 valid. 1732 173320170215: 1734 MCA bus support has been removed. 1735 173620170127: 1737 The WITH_LLD_AS_LD / WITHOUT_LLD_AS_LD build knobs have been renamed 1738 WITH_LLD_IS_LD / WITHOUT_LLD_IS_LD, for consistency with CLANG_IS_CC. 1739 174020170112: 1741 The EM_MULTIQUEUE kernel configuration option is deprecated now that 1742 the em(4) driver conforms to iflib specifications. 1743 174420170109: 1745 The igb(4), em(4) and lem(4) ethernet drivers are now implemented via 1746 IFLIB. If you have a custom kernel configuration that excludes em(4) 1747 but you use igb(4), you need to re-add em(4) to your custom 1748 configuration. 1749 175020161217: 1751 Clang, llvm, lldb, compiler-rt and libc++ have been upgraded to 3.9.1. 1752 Please see the 20141231 entry below for information about prerequisites 1753 and upgrading, if you are not already using clang 3.5.0 or higher. 1754 175520161124: 1756 Clang, llvm, lldb, compiler-rt and libc++ have been upgraded to 3.9.0. 1757 Please see the 20141231 entry below for information about prerequisites 1758 and upgrading, if you are not already using clang 3.5.0 or higher. 1759 176020161119: 1761 The layout of the pmap structure has changed for powerpc to put the pmap 1762 statistics at the front for all CPU variations. libkvm(3) and all tools 1763 that link against it need to be recompiled. 1764 176520161030: 1766 isl(4) and cyapa(4) drivers now require a new driver, 1767 chromebook_platform(4), to work properly on Chromebook-class hardware. 1768 On other types of hardware the drivers may need to be configured using 1769 device hints. Please see the corresponding manual pages for details. 1770 177120161017: 1772 The urtwn(4) driver was merged into rtwn(4) and now consists of 1773 rtwn(4) main module + rtwn_usb(4) and rtwn_pci(4) bus-specific 1774 parts. 1775 Also, firmware for RTL8188CE was renamed due to possible name 1776 conflict (rtwnrtl8192cU(B) -> rtwnrtl8192cE(B)) 1777 177820161015: 1779 GNU rcs has been removed from base. It is available as packages: 1780 - rcs: Latest GPLv3 GNU rcs version. 1781 - rcs57: Copy of the latest version of GNU rcs (GPLv2) before it was 1782 removed from base. 1783 178420161008: 1785 Use of the cc_cdg, cc_chd, cc_hd, or cc_vegas congestion control 1786 modules now requires that the kernel configuration contain the 1787 TCP_HHOOK option. (This option is included in the GENERIC kernel.) 1788 178920161003: 1790 The WITHOUT_ELFCOPY_AS_OBJCOPY src.conf(5) knob has been retired. 1791 ELF Tool Chain's elfcopy is always installed as /usr/bin/objcopy. 1792 179320160924: 1794 Relocatable object files with the extension of .So have been renamed 1795 to use an extension of .pico instead. The purpose of this change is 1796 to avoid a name clash with shared libraries on case-insensitive file 1797 systems. On those file systems, foo.So is the same file as foo.so. 1798 179920160918: 1800 GNU rcs has been turned off by default. It can (temporarily) be built 1801 again by adding WITH_RCS knob in src.conf. 1802 Otherwise, GNU rcs is available from packages: 1803 - rcs: Latest GPLv3 GNU rcs version. 1804 - rcs57: Copy of the latest version of GNU rcs (GPLv2) from base. 1805 180620160918: 1807 The backup_uses_rcs functionality has been removed from rc.subr. 1808 180920160908: 1810 The queue(3) debugging macro, QUEUE_MACRO_DEBUG, has been split into 1811 two separate components, QUEUE_MACRO_DEBUG_TRACE and 1812 QUEUE_MACRO_DEBUG_TRASH. Define both for the original 1813 QUEUE_MACRO_DEBUG behavior. 1814 181520160824: 1816 r304787 changed some ioctl interfaces between the iSCSI userspace 1817 programs and the kernel. ctladm, ctld, iscsictl, and iscsid must be 1818 rebuilt to work with new kernels. __FreeBSD_version has been bumped 1819 to 1200005. 1820 182120160818: 1822 The UDP receive code has been updated to only treat incoming UDP 1823 packets that were addressed to an L2 broadcast address as L3 1824 broadcast packets. It is not expected that this will affect any 1825 standards-conforming UDP application. The new behaviour can be 1826 disabled by setting the sysctl net.inet.udp.require_l2_bcast to 1827 0. 1828 182920160818: 1830 Remove the openbsd_poll system call. 1831 __FreeBSD_version has been bumped because of this. 1832 183320160708: 1834 The stable/11 branch has been created from head@r302406. 1835 1836After branch N is created, entries older than the N-2 branch point are removed 1837from this file. After stable/14 is branched and current becomes FreeBSD 15, 1838entries older than stable/12 branch point will be removed from current's 1839UPDATING file. 1840 1841COMMON ITEMS: 1842 1843 General Notes 1844 ------------- 1845 Sometimes, obscure build problems are the result of environment 1846 poisoning. This can happen because the make utility reads its 1847 environment when searching for values for global variables. To run 1848 your build attempts in an "environmental clean room", prefix all make 1849 commands with 'env -i '. See the env(1) manual page for more details. 1850 Occasionally a build failure will occur with "make -j" due to a race 1851 condition. If this happens try building again without -j, and please 1852 report a bug if it happens consistently. 1853 1854 When upgrading from one major version to another it is generally best to 1855 upgrade to the latest code in the currently installed branch first, then 1856 do an upgrade to the new branch. This is the best-tested upgrade path, 1857 and has the highest probability of being successful. Please try this 1858 approach if you encounter problems with a major version upgrade. Since 1859 the stable 4.x branch point, one has generally been able to upgrade from 1860 anywhere in the most recent stable branch to head / current (or even the 1861 last couple of stable branches). See the top of this file when there's 1862 an exception. 1863 1864 The update process will emit an error on an attempt to perform a build 1865 or install from a FreeBSD version below the earliest supported version. 1866 When updating from an older version the update should be performed one 1867 major release at a time, including running `make delete-old` at each 1868 step. 1869 1870 When upgrading a live system, having a root shell around before 1871 installing anything can help undo problems. Not having a root shell 1872 around can lead to problems if pam has changed too much from your 1873 starting point to allow continued authentication after the upgrade. 1874 1875 This file should be read as a log of events. When a later event changes 1876 information of a prior event, the prior event should not be deleted. 1877 Instead, a pointer to the entry with the new information should be 1878 placed in the old entry. Readers of this file should also sanity check 1879 older entries before relying on them blindly. Authors of new entries 1880 should write them with this in mind. 1881 1882 ZFS notes 1883 --------- 1884 When upgrading the boot ZFS pool to a new version (via zpool upgrade), 1885 always follow these three steps: 1886 1887 1) recompile and reinstall the ZFS boot loader and boot block 1888 (this is part of "make buildworld" and "make installworld") 1889 1890 2) update the ZFS boot block on your boot drive (only required when 1891 doing a zpool upgrade): 1892 1893 When booting on x86 via BIOS, use the following to update the ZFS boot 1894 block on the freebsd-boot partition of a GPT partitioned drive ada0: 1895 gpart bootcode -p /boot/gptzfsboot -i $N ada0 1896 The value $N will typically be 1. For EFI booting, see EFI notes. 1897 1898 3) zpool upgrade the root pool. New bootblocks will work with old 1899 pools, but not vice versa, so they need to be updated before any 1900 zpool upgrade. 1901 1902 Non-boot pools do not need these updates. 1903 1904 EFI notes 1905 --------- 1906 1907 There are two locations the boot loader can be installed into. The 1908 current location (and the default) is \efi\freebsd\loader.efi and using 1909 efibootmgr(8) to configure it. The old location, that must be used on 1910 deficient systems that don't honor efibootmgr(8) protocols, is the 1911 fallback location of \EFI\BOOT\BOOTxxx.EFI. Generally, you will copy 1912 /boot/loader.efi to this location, but on systems installed a long time 1913 ago the ESP may be too small and /boot/boot1.efi may be needed unless 1914 the ESP has been expanded in the meantime. 1915 1916 Recent systems will have the ESP mounted on /boot/efi, but older ones 1917 may not have it mounted at all, or mounted in a different 1918 location. Older arm SD images with MBR used /boot/msdos as the 1919 mountpoint. The ESP is a MSDOS filesystem. 1920 1921 The EFI boot loader rarely needs to be updated. For ZFS booting, 1922 however, you must update loader.efi before you do 'zpool upgrade' the 1923 root zpool, otherwise the old loader.efi may reject the upgraded zpool 1924 since it does not automatically understand some new features. 1925 1926 See loader.efi(8) and uefi(8) for more details. 1927 1928 To build a kernel 1929 ----------------- 1930 If you are updating from a prior version of FreeBSD (even one just 1931 a few days old), you should follow this procedure. It is the most 1932 failsafe as it uses a /usr/obj tree with a fresh mini-buildworld, 1933 1934 make kernel-toolchain 1935 make -DALWAYS_CHECK_MAKE buildkernel KERNCONF=YOUR_KERNEL_HERE 1936 make -DALWAYS_CHECK_MAKE installkernel KERNCONF=YOUR_KERNEL_HERE 1937 1938 If you are running kernel modules from ports, see FOOTNOTE [1]. 1939 1940 To test a kernel once 1941 --------------------- 1942 If you just want to boot a kernel once (because you are not sure 1943 if it works, or if you want to boot a known bad kernel to provide 1944 debugging information) run 1945 make installkernel KERNCONF=YOUR_KERNEL_HERE KODIR=/boot/testkernel 1946 nextboot -k testkernel 1947 1948 To rebuild everything and install it on the current system. 1949 ----------------------------------------------------------- 1950 # Note: sometimes if you are running current you gotta do more than 1951 # is listed here if you are upgrading from a really old current. 1952 1953 <make sure you have good level 0 dumps> 1954 make buildworld 1955 make buildkernel KERNCONF=YOUR_KERNEL_HERE 1956 make installkernel KERNCONF=YOUR_KERNEL_HERE [1] 1957 <reboot in single user> [3] 1958 etcupdate -p [5] 1959 make installworld 1960 etcupdate -B [4] 1961 make delete-old [6] 1962 <reboot> 1963 1964 To cross-install current onto a separate partition 1965 -------------------------------------------------- 1966 # In this approach we use a separate partition to hold 1967 # current's root, 'usr', and 'var' directories.

At this point in the life 2003 cycle of current, things change often and you are on your own 2004 to cope. The defaults can also change, so please read ALL of 2005 the UPDATING entries. 2006 2007 Also, if you are tracking -current, you must be subscribed to 2008 [email protected]. Make sure that before you update 2009 your sources that you have read and understood all the recent 2010 messages there. If in doubt, please track -stable which has 2011 much fewer pitfalls. 2012 2013FOOTNOTES: 2014 2015 [1] If you have third party modules, such as drm-kmod or vmware, you 2016 should disable them at this point so they don't crash your system on 2017 reboot. Alternatively, you should rebuild all the modules you have in 2018 your system and install them as well. If you are running -current, you 2019 should seriously consider placing all sources to all the modules for 2020 your system (or symlinks to them) in /usr/local/sys/modules so this 2021 happens automatically. If all your modules come from ports, then adding 2022 the port origin directories to PORTS_MODULES instead is also automatic 2023 and effective, eg: 2024 PORTS_MODULES+=x11/nvidia-driver 2025 2026 [3] From the bootblocks, boot -s, and then do 2027 fsck -p 2028 mount -u / 2029 mount -a 2030 sh /etc/rc.d/zfs start # mount zfs filesystem, if needed 2031 cd src # full path to source 2032 adjkerntz -i # if CMOS is wall time 2033 Also, when doing a major release upgrade, it is required that you boot 2034 into single user mode to do the installworld. 2035 2036 [4] Note: This step is non-optional. Failure to do this step 2037 can result in a significant reduction in the functionality of the 2038 system. Attempting to do it by hand is not recommended and those 2039 that pursue this avenue should read this file carefully, as well 2040 as the archives of freebsd-current and freebsd-hackers mailing lists 2041 for potential gotchas. See etcupdate(8) for more information. 2042 2043 [5] Usually this step is a no-op. However, from time to time 2044 you may need to do this if you get unknown user in the following 2045 step. 2046 2047 [6] This only deletes old files and directories. Old libraries 2048 can be deleted by "make delete-old-libs", but you have to make 2049 sure that no program is using those libraries anymore. 2050 2051 [8] The new kernel must be able to run existing binaries used by an 2052 installworld. When upgrading across major versions, the new kernel's 2053 configuration must include the correct COMPAT_FREEBSD<n> option for 2054 existing binaries (e.g. COMPAT_FREEBSD11 to run 11.x binaries). Failure 2055 to do so may leave you with a system that is hard to boot to recover. A 2056 GENERIC kernel will include suitable compatibility options to run 2057 binaries from older branches. Note that the ability to run binaries 2058 from unsupported branches is not guaranteed. 2059 2060 Make sure that you merge any new devices from GENERIC since the 2061 last time you updated your kernel config file. Options also 2062 change over time, so you may need to adjust your custom kernels 2063 for these as well. 2064 2065 [9] If CPUTYPE is defined in your /etc/make.conf, make sure to use the 2066 "?=" instead of the "=" assignment operator, so that buildworld can 2067 override the CPUTYPE if it needs to. 2068 2069 MAKEOBJDIRPREFIX must be defined in an environment variable, and 2070 not on the command line, or in /etc/make.conf. buildworld will 2071 warn if it is improperly defined. 2072FORMAT: 2073 2074This file contains a list, in reverse chronological order, of major 2075breakages in tracking -current. It is not guaranteed to be a complete 2076list of such breakages, and only contains entries since September 23, 2011. 2077If you need to see UPDATING entries from before that date, you will need 2078to fetch an UPDATING file from an older FreeBSD release. 2079 2080Copyright information: 2081 2082Copyright 1998-2009 M.
