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 1520230924: 16 Enable splitting out pkgbase manpages into separate packages by 17 default. To disable this, set WITHOUT_MANSPLITPKG=yes in src.conf. 18 19 2020230924: 21 Move standard include files to the clibs-dev package and move clang 22 internal libraries and headers to clang and clang-dev. Upgrading systems 23 installed using pkgbase past this change involves extra steps to allow 24 for these file moves: 25 26 pkg upgrade -y FreeBSD-utilities 27 pkg upgrade -y FreeBSD-utilities-dev 28 pkg upgrade -y 29 3020230824: 31 __FreeBSD_version 1400097 after the branching stable/14 from main. 32 3320230817: 34 Serial communication (in boot loaders, kernel, and userland) has 35 been changed to default to 115200 bps, in line with common industry 36 practice and typcial firmware serial console redirection 37 configuration. 38 39 Note that the early x86 BIOS bootloader (i.e., boot0sio) does not 40 support rates above 9600 bps and is not changed. boot0sio users may 41 set BOOT_COMCONSOLE_SPEED=9600 to use 9600 for all of the boot 42 components, or use the standard boot0 and have the boot2 stage start 43 with the serial port at 115200. 44 4520230807: 46 Following the general removal of MIPS support, the ath(4) AHB bus- 47 frontend has been removed, too, and building of the PCI support is 48 integrated with the ath(4) main module again. As a result, there's 49 no longer a need for if_ath_pci_load="YES" in /boot/loader.conf or 50 "device ath_pci" in the kernel configuration. 51 5220230803: 53 MAXCPU has been increased to 1024 in the amd64 GENERIC kernel config. 54 Out-of-tree kernel modules will need to be rebuilt. 55 5620230724: 57 CAM has been mechanically updated s/u_int(64|32|16|8)_t/uint\1_t/g 58 to move to the standard uintXX_t types from the old, traditional 59 BSD u_intXX_t types. This should be a NOP, but may cause problems 60 for out of tree changes. The SIMs were not updated since most of 61 the old u_intXX_t uses weren't due to CAM interfaces. 62 6320230629: 64 The heuristic for detecting old chromebooks with an EC bug that requires 65 atkbdc driver workarounds has changed. There should be no functional 66 change, but if your old chromebook's keyboard stops working, please 67 file a PR and assign it to imp. 68 6920230623: 70 OpenSSL has been updated to version 3.0, including changes throughout 71 the base system. It is important to rebuild third-party software 72 after upgrading. 73 7420230619: 75 To enable pf rdr rules for connections initiated from the host, pf 76 filter rules can be optionally enabled for packets delivered 77 locally. This can change the behavior of rules which match packets 78 delivered to lo0. To enable this feature: 79 80 sysctl net.pf.filter_local=1 81 service pf restart 82 83 When enabled, its best to ensure that packets delivered locally are not 84 filtered, e.g. by adding a 'skip on lo' rule. 85 8620230613: 87 Improvements to libtacplus(8) mean that tacplus.conf(5) now 88 follows POSIX shell syntax rules. This may cause TACACS+ 89 authentication to fail if the shared secret contains a single 90 quote, double quote, or backslash character which isn't 91 already properly quoted or escaped. 92 9320230612: 94 Belatedly switch the default nvme block device on x86 from nvd to nda. 95 nda created nvd compatibility links by default, so this should be a 96 nop. If this causes problems for your application, set hw.nvme.use_nvd=1 97 in your loader.conf or add `options NVME_USE_NVD=1` to your kernel 98 config. To disable the nvd compatibility aliases, add 99 kern.cam.nda.nvd_compat=0 to loader.conf. The default has been nda on 100 all non-x86 platforms for some time now. If you need to fall back, 101 please email [email protected] about why. 102 103 Encrypted swap partitions need to be changed from nvd to nda if you 104 migrate, or you need to use the above to switch back to nvd. 105 10620230422: 107 Remove portsnap(8). Users are encouraged to obtain the ports tree 108 using git instead. 109 11020230420: 111 Add jobs.mk to save typing. Enables -j${JOB_MAX} and logging 112 eg. 113 make buildworld-jobs 114 runs 115 make -j${JOB_MAX} buildworld > ../buildworld.log 2>&1 116 117 where JOB_MAX is derrived from ncpus in local.sys.mk if not set in env. 118 11920230316: 120 Video related devices for some arm devices have been renamed. 121 If you have a custom kernel config and want to use hdmi output on 122 IMX6 board you need to add "device dwc_hdmi" "device imx6_hdmi" and 123 "device imx6_ipu" to it. 124 If you have a custom kernel config and want to use hdmi output on 125 TI AM335X board you need to add "device tda19988" to it. 126 If you add "device hdmi" in it you need to remove it as it doesn't 127 exist anymore. 128 12920230221: 130 Introduce new kernel options KBD_DELAY1 and KBD_DELAY2. See atkbdc(4) 131 for details. 132 13320230206: 134 sshd now defaults to having X11Forwarding disabled, following upstream. 135 Administrators who wish to enable X11Forwarding should add 136 `X11Forwarding yes` to /etc/ssh/sshd_config. 137 13820230204: 139 Since commit 75d41cb6967 Huawei 3G/4G LTE Mobile Devices do not default 140 to ECM, but NCM mode and need u3g and ucom modules loaded. See cdce(4). 141 14220230130: 143 As of commit 7c40e2d5f685, the dependency on netlink(4) has been added 144 to the linux_common(4) module. Users relying on linux_common may need 145 to complile netlink(4) module if it is not present in their kernel. 146 14720230126: 148 The WITHOUT_CXX option has been removed. C++ components in the base 149 system are now built unconditionally. 150 15120230113: 152 LinuxKPI pci.h changes may require out-of-tree drivers to be recompiled. 153 Bump _FreeBSD_version to 1400078 to be able to detect this change. 154 15520221212: 156 llvm-objump is now always installed as objdump. Previously there was 157 no /usr/bin/objdump unless the WITH_LLVM_BINUTILS knob was used. 158 159 Some LLVM objdump options have a different output format compared to 160 GNU objdump; readelf is available for inspecting ELF files, and GNU 161 objdump is available from the devel/binutils port or package. 162 16320221205: 164 dma(8) has replaced sendmail(8) as the default mta. For people willing 165 to reenable sendmail(8): 166 167 $ cp /usr/share/examples/sendmail/mailer.conf /etc/mail/mailer.conf 168 169 and add sendmail_enable="YES" to rc.conf. 170 17120221204: 172 hw.bus.disable_failed_devices has changed from 'false' to 'true' by 173 default. Now if newbus succeeds in probing a device, but fails to attach 174 the device, we'll disable the device. In the past, we'd keep retrying 175 the device on each new driver loaded. To get that behavior now, one 176 needs to use devctl to re-enable the device, and reprobe it (or set 177 the sysctl/tunable hw.bus.disable_failed_devices=false). 178 179 NOTE: This was reverted 20221205 due to unexpected compatibility issues 180 18120221122: 182 pf no longer accepts 'scrub fragment crop' or 'scrub fragment drop-ovl'. 183 These configurations are no longer automatically reinterpreted as 184 'scrub fragment reassemble'. 185 18620221121: 187 The WITHOUT_CLANG_IS_CC option has been removed. When Clang is enabled 188 it is always installed as /usr/bin/cc (and c++, cpp). 189 19020221026: 191 Some programs have been moved into separate packages. It is recommended 192 for pkgbase users to do: 193 194 pkg install FreeBSD-dhclient FreeBSD-geom FreeBSD-resolvconf \ 195 FreeBSD-devd FreeBSD-devmatch 196 197 after upgrading to restore all the component that were previously 198 installed. 199 20020221002: 201 OPIE has been removed from the base system. If needed, it can 202 be installed from ports (security/opie) or packages (opie). 203 Otherwise, make sure that your PAM policies do not reference 204 pam_opie or pam_opieaccess. 205 20620220610: 207 LinuxKPI pm.h changes require an update to the latest drm-kmod version 208 before re-compiling to avoid errors. 209 21020211230: 211 The macros provided for the manipulation of CPU sets (e.g. CPU_AND) 212 have been modified to take 2 source arguments instead of only 1. 213 Externally maintained sources that use these macros will have to 214 be adapted. The FreeBSD version has been bumped to 1400046 to 215 reflect this change. 216 21720211214: 218 A number of the kernel include files are able to be included by 219 themselves. A test has been added to buildworld to enforce this. 220 22120211209: 222 Remove mips as a recognized target. This starts the decommissioning of 223 mips support in FreeBSD. mips related items will be removed wholesale in 224 the coming days and weeks. 225 226 This broke the NO_CLEAN build for some people. Either do a clean build 227 or touch 228 lib/clang/include/llvm/Config/Targets.def 229 lib/clang/include/llvm/Config/AsmParsers.def 230 lib/clang/include/llvm/Config/Disassemblers.def 231 lib/clang/include/llvm/Config/AsmPrinters.def 232 before the build to force everything to rebuild that needs to. 233 23420211202: 235 Unbound support for RFC8375: The special-use domain 'home.arpa' is 236 by default blocked. To unblock it use a local-zone nodefault 237 statement in unbound.conf: 238 local-zone: "home.arpa." nodefault 239 240 Or use another type of local-zone to override with your choice. 241 242 The reason for this is discussed in Section 6.1 of RFC8375: 243 Because 'home.arpa.' is not globally scoped and cannot be secured 244 using DNSSEC based on the root domain's trust anchor, there is no way 245 to tell, using a standard DNS query, in which homenet scope an answer 246 belongs. Consequently, users may experience surprising results with 247 such names when roaming to different homenets. 248 24920211110: 250 Commit b8d60729deef changed the TCP congestion control framework so 251 that any of the included congestion control modules could be 252 the single module built into the kernel. Previously newreno 253 was automatically built in through direct reference. As of 254 this commit you are required to declare at least one congestion 255 control module (e.g. 'options CC_NEWRENO') and to also declare a 256 default using the CC_DEFAULT option (e.g. options CC_DEFAULT="newreno\"). 257 The GENERIC configuration includes CC_NEWRENO and defines newreno 258 as the default. If no congestion control option is built into the 259 kernel and you are including networking, the kernel compile will 260 fail. Also if no default is declared the kernel compile will fail. 261 26220211118: 263 Mips has been removed from universe builds. It will be removed from the 264 tree shortly. 265 26620211106: 267 Commit f0c9847a6c47 changed the arguments for VOP_ALLOCATE. 268 The NFS modules must be rebuilt from sources and any out 269 of tree file systems that implement their own VOP_ALLOCATE 270 may need to be modified. 271 27220211022: 273 The synchronous PPP kernel driver sppp(4) has been removed. 274 The cp(4) and ce(4) drivers are now always compiled with netgraph(4) 275 support, formerly enabled by NETGRAPH_CRONYX option. 276 27720211020: 278 sh(1) is now the default shell for the root user. To force root to use 279 the csh shell, please run the following command as root: 280 281 # chsh -s csh 282 28320211004: 284 Ncurses distribution has been split between libtinfow and libncurses 285 with libncurses.so becoming a linker (ld) script to seamlessly link 286 to libtinfow as needed. Bump _FreeBSD_version to 1400035 to reflect 287 this change. 288 28920210923: 290 As of commit 8160a0f62be6, the dummynet module no longer depends on the 291 ipfw module. Dummynet can now be used by pf as well as ipfw. As such 292 users who relied on this dependency may need to include ipfw in the 293 list of modules to load on their systems. 294 29520210922: 296 As of commit 903873ce1560, the mixer(8) utility has got a slightly 297 new syntax. Please refer to the mixer(8) manual page for more 298 information. The old mixer utility can be installed from ports: 299 audio/freebsd-13-mixer 300 30120210911: 302 As of commit 55089ef4f8bb, the global variable nfs_maxcopyrange has 303 been deleted from the nfscommon.ko. As such, nfsd.ko must be built 304 from up to date sources to avoid an undefined reference when 305 being loaded. 306 30720210817: 308 As of commit 62ca9fc1ad56 OpenSSL no longer enables kernel TLS 309 by default. Users can enable kernel TLS via the "KTLS" SSL 310 option. This can be enabled globally by using a custom 311 OpenSSL config file via OPENSSL_CONF or via an 312 application-specific configuration option for applications 313 which permit setting SSL options via SSL_CONF_cmd(3). 314 31520210811: 316 Commit 3ad1e1c1ce20 changed the internal KAPI between the NFS 317 modules. Therefore, all need to be rebuilt from sources. 318 31920210730: 320 Commit b69019c14cd8 removes pf's DIOCGETSTATESNV ioctl. 321 As of be70c7a50d32 it is no longer used by userspace, but it does mean 322 users may not be able to enumerate pf states if they update the kernel 323 past b69019c14cd8 without first updating userspace past be70c7a50d32. 324 32520210729: 326 As of commit 01ad0c007964 if_bridge member interfaces can no longer 327 change their MTU. Changing the MTU of the bridge itself will change the 328 MTU on all member interfaces instead. 329 33020210716: 331 Commit ee29e6f31111 changed the internal KAPI between the nfscommon 332 and nfsd modules. Therefore, both need to be rebuilt from sources. 333 Bump __FreeBSD_version to 1400026 for this KAPI change. 334 33520210715: 336 The 20210707 awk update brought in a change in behavior. This has 337 been corrected as of d4d252c49976. Between these dates, if you 338 installed a new awk binary, you may not be able to build a new 339 kernel because the change in behavior affected the genoffset 340 script used to build the kernel. If you did update, the fix is 341 to update your sources past the above hash and do 342 % cd usr.bin/awk 343 % make clean all 344 % sudo -E make install 345 to enable building kernels again. 346 34720210708: 348 Commit 1e0a518d6548 changed the internal KAPI between the NFS 349 modules. They all need to be rebuilt from sources. I did not 350 bump __FreeBSD_version, since it was bumped recently. 351 35220210707: 353 awk has been updated to the latest one-true-awk version 20210215. 354 This contains a number of minor bug fixes. 355 35620210624: 357 The NFSv4 client now uses the highest minor version of NFSv4 358 supported by the NFSv4 server by default instead of minor version 0, 359 for NFSv4 mounts. 360 The "minorversion" mount option may be used to override this default. 361 36220210618: 363 Bump __FreeBSD_version to 1400024 for LinuxKPI changes. 364 Most notably netdev.h can change now as the (last) dependencies 365 (mlx4/ofed) are now using struct ifnet directly, but also for PCI 366 additions and others. 367 36820210618: 369 The directory "blacklisted" under /usr/share/certs/ has been 370 renamed to "untrusted". 371 37220210611: 373 svnlite has been removed from base. Should you need svn for any reason 374 please install the svn package or port. 375 37620210611: 377 Commit e1a907a25cfa changed the internal KAPI between the krpc 378 and nfsserver. As such, both modules must be rebuilt from 379 sources. Bump __FreeBSD_version to 1400022. 380 38120210610: 382 The an(4) driver has been removed from FreeBSD. 383 38420210608: 385 The vendor/openzfs branch was renamed to vendor/openzfs/legacy to 386 start tracking OpenZFS upstream more closely. Please see 387https://lists.freebsd.org/archives/freebsd-current/2021-June/000153.html 388 for details on how to correct any errors that might result. The 389 short version is that you need to remove the old branch locally: 390 git update-ref -d refs/remotes/freebsd/vendor/openzfs 391 (assuming your upstream origin is named 'freebsd'). 392 39320210525: 394 Commits 17accc08ae15 and de102f870501 add new files to LinuxKPI 395 which break drm-kmod. In addition various other additions where 396 committed. Bump __FreeBSD_version to 1400015 to be able to 397 detect this. 398 39920210513: 400 Commit ca179c4d74f2 changed the package in which the OpenSSL 401 libraries and utilities are packaged. 402 It is recommended for pkgbase user to do: 403 pkg install -f FreeBSD-openssl 404 before pkg upgrade otherwise some dependencies might not be met 405 and pkg will stop working as libssl will not be present anymore 406 on the system. 407 40820210426: 409 Commit 875977314881 changed the internal KAPI between 410 the nfsd and nfscommon modules. As such these modules 411 need to be rebuilt from sources. 412 Without this patch in your NFSv4.1/4.2 server, enabling 413 delegations by setting vfs.nfsd.issue_delegations non-zero 414 is not recommended. 415 41620210411: 417 Commit 7763814fc9c2 changed the internal KAPI between 418 the krpc and NFS. As such, the krpc, nfscommon and 419 nfscl modules must all be rebuilt from sources. 420 Without this patch, NFSv4.1/4.2 mounts should not 421 be done with the nfscbd(8) daemon running, to avoid 422 needing a working back channel for server->client RPCs. 423 42420210330: 425 Commit 01ae8969a9ee fixed the NFSv4.1/4.2 server so that it 426 handles binding of the back channel as required by RFC5661. 427 Until this patch is in your server, avoid use of the "nconnects" 428 mount option for Linux NFSv4.1/4.2 mounts. 429 43020210225: 431 For 64-bit architectures the base system is now built with Position 432 Independent Executable (PIE) support enabled by default. It may be 433 disabled using the WITHOUT_PIE knob. A clean build is required. 434 43520210128: 436 Various LinuxKPI functionality was added which conflicts with DRM. 437 Please update your drm-kmod port to after the __FreeBSD_version 1400003 438 update. 439 44020210108: 441 PC Card attachments for all devices have been removed. In the case of 442 wi and cmx, the entire drivers were removed because they were only 443 PC Card devices. FreeBSD_version 1300134 should be used for this 444 since it was bumped so recently. 445 44620210107: 447 Transport-independent parts of HID support have been split off the USB 448 code in to separate subsystem. Kernel configs which include one of 449 ums, ukbd, uhid, atp, wsp, wmt, uaudio, ugold or ucycom drivers should 450 be updated with adding of "device hid" line. 451 45220210105: 453 ncurses installation has been modified to only keep the widechar 454 enabled version. Incremental build is broken for that change, so it 455 requires a clean build. 456 45720201223: 458 The FreeBSD project has migrated from Subversion to Git. Temporary 459 instructions can be found at 460 https://github.com/bsdimp/freebsd-git-docs/blob/main/src-cvt.md 461 and other documents in that repo. 462 46320201216: 464 The services database has been updated to cover more of the basic 465 services expected in a modern system. The database is big enough 466 that it will cause issues in mergemaster in Releases previous to 467 12.2 and 11.3, or in very old current systems from before r358154. 468 46920201215: 470 Obsolete in-tree GDB 6.1.1 has been removed. GDB (including kgdb) 471 may be installed from ports or packages. 472 47320201124: 474 ping6 has been merged into ping. It can now be called as "ping -6". 475 See ping(8) for details. 476 47720201108: 478 Default value of net.add_addr_allfibs has been changed to 0. 479 If you have multi-fib configuration and rely on existence of all 480 interface routes in every fib, you need to set the above sysctl to 1. 481 48220201030: 483 The internal pre-processor in the calendar(1) program has been 484 extended to support more C pre-processor commands (e.g. #ifdef, #else, 485 and #undef) and to detect unbalanced conditional statements. 486 Error messages have been extended to include the filename and line 487 number if processing stops to help fixing malformed data files. 488 48920201026: 490 All the data files for the calendar(1) program, except calendar.freebsd, 491 have been moved to the deskutils/calendar-data port, much like the 492 jewish calendar entries were moved to deskutils/hebcal years ago. After 493 make delete-old-files, you need to install it to retain full 494 functionality. calendar(1) will issue a reminder for files it can't 495 find. 496 49720200923: 498 LINT files are no longer generated. We now include the relevant NOTES 499 files. Note: This may cause conflicts with updating in some cases. 500 find sys -name LINT\* -delete 501 is suggested across this commit to remove the generated LINT files. 502 503 If you have tried to update with generated files there, the svn 504 command you want to un-auger the tree is 505 cd sys/amd64/conf 506 svn revert -R . 507 and then do the above find from the top level. Substitute 'amd64' 508 above with where the error message indicates a conflict. 509 51020200824: 511 OpenZFS support has been integrated. Do not upgrade root pools until 512 the loader is updated to support zstd. Furthermore, we caution against 513 'zpool upgrade' for the next few weeks. The change should be transparent 514 unless you want to use new features. 515 516 Not all "NO_CLEAN" build scenarios work across these changes. Many 517 scenarios have been tested and fixed, but rebuilding kernels without 518 rebuilding world may fail. 519 520 The ZFS cache file has moved from /boot to /etc to match the OpenZFS 521 upstream default. A fallback to /boot has been added for mountroot. 522 523 Pool auto import behavior at boot has been moved from the kernel module 524 to an explicit "zpool import -a" in one of the rc scripts enabled by 525 zfs_enable=YES. This means your non-root zpools won't auto import until 526 you upgrade your /etc/rc.d files. 527 52820200824: 529 The resume code now notifies devd with the 'kernel' system 530 rather than the old 'kern' subsystem to be consistent with 531 other use. The old notification will be created as well, but 532 will be removed prior to FreeBSD 14.0. 533 53420200821: 535 r362275 changed the internal API between the kernel RPC and the 536 NFS modules. As such, all the modules must be recompiled from 537 sources. 538 53920200817: 540 r364330 modified the internal API used between the NFS modules. 541 As such, all the NFS modules must be re-compiled from sources. 542 54320200816: 544 Clang, llvm, lld, lldb, compiler-rt, libc++, libunwind and openmp have 545 been upgraded to 11.0.0. Please see the 20141231 entry below for 546 information about prerequisites and upgrading, if you are not already 547 using clang 3.5.0 or higher. 548 54920200810: 550 r364092 modified the internal ABI used between the kernel NFS 551 modules. As such, all of these modules need to be rebuilt 552 from sources, so a version bump was done. 553 55420200807: 555 Makefile.inc has been updated to work around the issue documented in 556 20200729. It was a case where the optimization of using symbolic links 557 to point to binaries created a situation where we'd run new binaries 558 with old libraries starting midway through the installworld process. 559 56020200729: 561 r363679 has redefined some undefined behavior in regcomp(3); notably, 562 extraneous escapes of most ordinary characters will no longer be 563 accepted. An exp-run has identified all of the problems with this in 564 ports, but other non-ports software may need extra escapes removed to 565 continue to function. 566 567 Because of this change, installworld may encounter the following error 568 from rtld: Undefined symbol "regcomp@FBSD_1.6" -- It is imperative that 569 you do not halt installworld. Instead, let it run to completion (whether 570 successful or not) and run installworld once more. 571 57220200627: 573 A new implementation of bc and dc has been imported in r362681. This 574 implementation corrects non-conformant behavior of the previous bc 575 and adds GNU bc compatible options. It offers a number of extensions, 576 is much faster on large values, and has support for message catalogs 577 (a number of languages are already supported, contributions of further 578 languages welcome). The option WITHOUT_GH_BC can be used to build the 579 world with the previous versions of bc and dc. 580 58120200625: 582 r362639 changed the internal API used between the NFS kernel modules. 583 As such, they all need to be rebuilt from sources. 584 58520200613: 586 r362158 changed the arguments for VFS_CHECKEXP(). As such, any 587 out of tree file systems need to be modified and rebuilt. 588 Also, any file systems that are modules must be rebuilt. 589 59020200604: 591 read(2) of a directory fd is now rejected by default. root may 592 re-enable it for system root only on non-ZFS filesystems with the 593 security.bsd.allow_read_dir sysctl(8) MIB if 594 security.bsd.suser_enabled=1. 595 596 It may be advised to setup aliases for grep to default to `-d skip` if 597 commonly non-recursively grepping a list that includes directories and 598 the potential for the resulting stderr output is not tolerable. Example 599 aliases are now installed, commented out, in /root/.cshrc and 600 /root/.shrc. 601 60220200523: 603 Clang, llvm, lld, lldb, compiler-rt, libc++, libunwind and openmp have 604 been upgraded to 10.0.1. Please see the 20141231 entry below for 605 information about prerequisites and upgrading, if you are not already 606 using clang 3.5.0 or higher. 607 60820200512: 609 Support for obsolete compilers has been removed from the build system. 610 Clang 6 and GCC 6.4 are the minimum supported versions. 611 61220200424: 613 closefrom(2) has been moved under COMPAT12, and replaced in libc with a 614 stub that calls close_range(2). If using a custom kernel configuration, 615 you may want to ensure that the COMPAT_FREEBSD12 option is included, as 616 a slightly older -CURRENT userland and older FreeBSD userlands may not 617 be functional without closefrom(2). 618 61920200414: 620 Upstream DTS from Linux 5.6 was merged and they now have the SID 621 and THS (Secure ID controller and THermal Sensor) node present. 622 The DTB overlays have now been removed from the tree for the H3/H5 and 623 A64 SoCs and the aw_sid and aw_thermal driver have been updated to 624 deal with upstream DTS. If you are using those overlays you need to 625 remove them from loader.conf and update the DTBs on the FAT partition. 626 62720200310: 628 Clang, llvm, lld, lldb, compiler-rt, libc++, libunwind and openmp have 629 been upgraded to 10.0.0. Please see the 20141231 entry below for 630 information about prerequisites and upgrading, if you are not already 631 using clang 3.5.0 or higher. 632 63320200309: 634 The amd(8) automount daemon has been removed from the source tree. 635 As of FreeBSD 10.1 autofs(5) is the preferred tool for automounting. 636 amd is still available in the sysutils/am-utils port. 637 63820200301: 639 Removed brooktree driver (bktr.4) from the tree. 640 64120200229: 642 The WITH_GPL_DTC option has been removed. The BSD-licenced device tree 643 compiler in usr.bin/dtc is used on all architectures which use dtc, and 644 the GPL dtc is available (if needed) from the sysutils/dtc port. 645 64620200229: 647 The WITHOUT_LLVM_LIBUNWIND option has been removed. LLVM's libunwind 648 is used by all supported CPU architectures. 649 65020200229: 651 GCC 4.2.1 has been removed from the tree. The WITH_GCC, 652 WITH_GCC_BOOTSTRAP, and WITH_GNUCXX options are no longer available. 653 Users who wish to build FreeBSD with GCC must use the external toolchain 654 ports or packages. 655 65620200220: 657 ncurses has been updated to a newer version (6.2-20200215). Given the ABI 658 has changed, users will have to rebuild all the ports that are linked to 659 ncurses. 660 66120200217: 662 The size of struct vnet and the magic cookie have changed. 663 Users need to recompile libkvm and all modules using VIMAGE 664 together with their new kernel. 665 66620200212: 667 Defining the long deprecated NO_CTF, NO_DEBUG_FILES, NO_INSTALLLIB, 668 NO_MAN, NO_PROFILE, and NO_WARNS variables is now an error. Update 669 your Makefiles and scripts to define MK_<var>=no instead as required. 670 671 One exception to this is that program or library Makefiles should 672 define MAN to empty rather than setting MK_MAN=no. 673 67420200108: 675 Clang/LLVM is now the default compiler and LLD the default 676 linker for riscv64. 677 67820200107: 679 make universe no longer uses GCC 4.2.1 on any architectures. 680 Architectures not supported by in-tree Clang/LLVM require an 681 external toolchain package. 682 68320200104: 684 GCC 4.2.1 is now not built by default, as part of the GCC 4.2.1 685 retirement plan. Specifically, the GCC, GCC_BOOTSTRAP, and GNUCXX 686 options default to off for all supported CPU architectures. As a 687 short-term transition aid they may be enabled via WITH_* options. 688 GCC 4.2.1 is expected to be removed from the tree on 2020-03-31. 689 69020200102: 691 Support for armv5 has been disconnected and is being removed. The 692 machine combination MACHINE=arm MACHINE_ARCH=arm is no longer valid. 693 You must now use a MACHINE_ARCH of armv6 or armv7. The default 694 MACHINE_ARCH for MACHINE=arm is now armv7. 695 69620191226: 697 Clang/LLVM is now the default compiler for all powerpc architectures. 698 LLD is now the default linker for powerpc64. The change for powerpc64 699 also includes a change to the ELFv2 ABI, incompatible with the existing 700 ABI. 701 70220191226: 703 Kernel-loadable random(4) modules are no longer unloadable. 704 70520191222: 706 Clang, llvm, lld, lldb, compiler-rt, libc++, libunwind and openmp have 707 been upgraded to 9.0.1. Please see the 20141231 entry below for 708 information about prerequisites and upgrading, if you are not already 709 using clang 3.5.0 or higher. 710 71120191212: 712 r355677 has modified the internal interface used between the 713 NFS modules in the kernel. As such, they must all be upgraded 714 simultaneously. I will do a version bump for this. 715 71620191205: 717 The root certificates of the Mozilla CA Certificate Store have been 718 imported into the base system and can be managed with the certctl(8) 719 utility. If you have installed the security/ca_root_nss port or package 720 with the ETCSYMLINK option (the default), be advised that there may be 721 differences between those included in the port and those included in 722 base due to differences in nss branch used as well as general update 723 frequency. Note also that certctl(8) cannot manage certs in the 724 format used by the security/ca_root_nss port. 725 72620191120: 727 The amd(8) automount daemon has been disabled by default, and will be 728 removed in the future. As of FreeBSD 10.1 the autofs(5) is available 729 for automounting. 730 73120191107: 732 The nctgpio and wbwd drivers have been moved to the superio bus. 733 If you have one of these drivers in a kernel configuration, then 734 you should add device superio to it. If you use one of these drivers 735 as a module and you compile a custom set of modules, then you should 736 add superio to the set. 737 73820191021: 739 KPIs for network drivers to access interface addresses have changed. 740 Users need to recompile NIC driver modules together with kernel. 741 74220191021: 743 The net.link.tap.user_open sysctl no longer prevents user opening of 744 already created /dev/tapNN devices. Access is still controlled by 745 node permissions, just like tun devices. The net.link.tap.user_open 746 sysctl is now used only to allow users to perform devfs cloning of 747 tap devices, and the subsequent open may not succeed if the user is not 748 in the appropriate group. This sysctl may be deprecated/removed 749 completely in the future. 750 75120191009: 752 mips, powerpc, and sparc64 are no longer built as part of 753 universe / tinderbox unless MAKE_OBSOLETE_GCC is defined. If 754 not defined, mips, powerpc, and sparc64 builds will look for 755 the xtoolchain binaries and if installed use them for universe 756 builds. As llvm 9.0 becomes vetted for these architectures, they 757 will be removed from the list. 758 75920191009: 760 Clang, llvm, lld, lldb, compiler-rt, libc++, libunwind and openmp have 761 been upgraded to 9.0.0. Please see the 20141231 entry below for 762 information about prerequisites and upgrading, if you are not already 763 using clang 3.5.0 or higher. 764 76520191003: 766 The hpt27xx, hptmv, hptnr, and hptrr drivers have been removed from 767 GENERIC. They are available as modules and can be loaded by adding 768 to /boot/loader.conf hpt27xx_load="YES", hptmv_load="YES", 769 hptnr_load="YES", or hptrr_load="YES", respectively. 770 77120190913: 772 ntpd no longer by default locks its pages in memory, allowing them 773 to be paged out by the kernel. Use rlimit memlock to restore 774 historic BSD behaviour. For example, add "rlimit memlock 32" 775 to ntp.conf to lock up to 32 MB of ntpd address space in memory. 776 77720190823: 778 Several of ping6's options have been renamed for better consistency 779 with ping. If you use any of -ARWXaghmrtwx, you must update your 780 scripts. See ping6(8) for details. 781 78220190727: 783 The vfs.fusefs.sync_unmount and vfs.fusefs.init_backgrounded sysctls 784 and the "-o sync_unmount" and "-o init_backgrounded" mount options have 785 been removed from mount_fusefs(8). You can safely remove them from 786 your scripts, because they had no effect. 787 788 The vfs.fusefs.fix_broken_io, vfs.fusefs.sync_resize, 789 vfs.fusefs.refresh_size, vfs.fusefs.mmap_enable, 790 vfs.fusefs.reclaim_revoked, and vfs.fusefs.data_cache_invalidate 791 sysctls have been removed. If you felt the need to set any of them to 792 a non-default value, please tell [email protected] why. 793 79420190713: 795 Default permissions on the /var/account/acct file (and copies of it 796 rotated by periodic daily scripts) are changed from 0644 to 0640 797 because the file contains sensitive information that should not be 798 world-readable. If the /var/account directory must be created by 799 rc.d/accounting, the mode used is now 0750. Admins who use the 800 accounting feature are encouraged to change the mode of an existing 801 /var/account directory to 0750 or 0700. 802 80320190620: 804 Entropy collection and the /dev/random device are no longer optional 805 components. The "device random" option has been removed. 806 Implementations of distilling algorithms can still be made loadable 807 with "options RANDOM_LOADABLE" (e.g., random_fortuna.ko). 808 80920190612: 810 Clang, llvm, lld, lldb, compiler-rt, libc++, libunwind and openmp have 811 been upgraded to 8.0.1. Please see the 20141231 entry below for 812 information about prerequisites and upgrading, if you are not already 813 using clang 3.5.0 or higher. 814 81520190608: 816 A fix was applied to i386 kernel modules to avoid panics with 817 dpcpu or vnet. Users need to recompile i386 kernel modules 818 having pcpu or vnet sections or they will refuse to load. 819 82020190513: 821 User-wired pages now have their own counter, 822 vm.stats.vm.v_user_wire_count. The vm.max_wired sysctl was renamed 823 to vm.max_user_wired and changed from an unsigned int to an unsigned 824 long. bhyve VMs wired with the -S are now subject to the user 825 wiring limit; the vm.max_user_wired sysctl may need to be tuned to 826 avoid running into the limit. 827 82820190507: 829 The IPSEC option has been removed from GENERIC. Users requiring 830 ipsec(4) must now load the ipsec(4) kernel module. 831 83220190507: 833 The tap(4) driver has been folded into tun(4), and the module has been 834 renamed to tuntap. You should update any kld_list="if_tap" or 835 kld_list="if_tun" entries in /etc/rc.conf, if_tap_load="YES" or 836 if_tun_load="YES" entries in /boot/loader.conf to load the if_tuntap 837 module instead, and "device tap" or "device tun" entries in kernel 838 config files to select the tuntap device instead. 839 84020190418: 841 The following knobs have been added related to tradeoffs between 842 safe use of the random device and availability in the absence of 843 entropy: 844 845 kern.random.initial_seeding.bypass_before_seeding: tunable; set 846 non-zero to bypass the random device prior to seeding, or zero to 847 block random requests until the random device is initially seeded. 848 For now, set to 1 (unsafe) by default to restore pre-r346250 boot 849 availability properties. 850 851 kern.random.initial_seeding.read_random_bypassed_before_seeding: 852 read-only diagnostic sysctl that is set when bypass is enabled and 853 read_random(9) is bypassed, to enable programmatic handling of this 854 initial condition, if desired. 855 856 kern.random.initial_seeding.arc4random_bypassed_before_seeding: 857 Similar to the above, but for arc4random(9) initial seeding. 858 859 kern.random.initial_seeding.disable_bypass_warnings: tunable; set 860 non-zero to disable warnings in dmesg when the same conditions are 861 met as for the diagnostic sysctls above. Defaults to zero, i.e., 862 produce warnings in dmesg when the conditions are met. 863 86420190416: 865 The loadable random module KPI has changed; the random_infra_init() 866 routine now requires a 3rd function pointer for a bool (*)(void) 867 method that returns true if the random device is seeded (and 868 therefore unblocked). 869 87020190404: 871 r345895 reverts r320698. This implies that an nfsuserd(8) daemon 872 built from head sources between r320757 (July 6, 2017) and 873 r338192 (Aug. 22, 2018) will not work unless the "-use-udpsock" 874 is added to the command line. 875 nfsuserd daemons built from head sources that are post-r338192 are 876 not affected and should continue to work. 877 87820190320: 879 The fuse(4) module has been renamed to fusefs(4) for consistency with 880 other filesystems. You should update any kld_load="fuse" entries in 881 /etc/rc.conf, fuse_load="YES" entries in /boot/loader.conf, and 882 "options FUSE" entries in kernel config files. 883 88420190304: 885 Clang, llvm, lld, lldb, compiler-rt and libc++ have been upgraded to 886 8.0.0. Please see the 20141231 entry below for information about 887 prerequisites and upgrading, if you are not already using clang 3.5.0 888 or higher. 889 89020190226: 891 geom_uzip(4) depends on the new module xz. If geom_uzip is statically 892 compiled into your custom kernel, add 'device xz' statement to the 893 kernel config. 894 89520190219: 896 drm and drm2 have been removed from the tree. Please see 897 https://wiki.freebsd.org/Graphics for the latest information on 898 migrating to the drm ports. 899 90020190131: 901 Iflib is no longer unconditionally compiled into the kernel. Drivers 902 using iflib and statically compiled into the kernel, now require 903 the 'device iflib' config option. For the same drivers loaded as 904 modules on kernels not having 'device iflib', the iflib.ko module 905 is loaded automatically. 906 90720190125: 908 The IEEE80211_AMPDU_AGE and AH_SUPPORT_AR5416 kernel configuration 909 options no longer exist since r343219 and r343427 respectively; 910 nothing uses them, so they should be just removed from custom 911 kernel config files. 912 91320181230: 914 r342635 changes the way efibootmgr(8) works by requiring users to add 915 the -b (bootnum) parameter for commands where the bootnum was previously 916 specified with each option. For example 'efibootmgr -B 0001' is now 917 'efibootmgr -B -b 0001'. 918 91920181220: 920 r342286 modifies the NFSv4 server so that it obeys vfs.nfsd.nfs_privport 921 in the same as it is applied to NFSv2 and 3. This implies that NFSv4 922 servers that have vfs.nfsd.nfs_privport set will only allow mounts 923 from clients using a reserved port. Since both the FreeBSD and Linux 924 NFSv4 clients use reserved ports by default, this should not affect 925 most NFSv4 mounts. 926 92720181219: 928 The XLP config has been removed. We can't support 64-bit atomics in this 929 kernel because it is running in 32-bit mode. XLP users must transition 930 to running a 64-bit kernel (XLP64 or XLPN32). 931 932 The mips GXEMUL support has been removed from FreeBSD. MALTA* + qemu is 933 the preferred emulator today and we don't need two different ones. 934 935 The old sibyte / swarm / Broadcom BCM1250 support has been 936 removed from the mips port. 937 93820181211: 939 Clang, llvm, lld, lldb, compiler-rt and libc++ have been upgraded to 940 7.0.1. Please see the 20141231 entry below for information about 941 prerequisites and upgrading, if you are not already using clang 3.5.0 942 or higher. 943 94420181211: 945 Remove the timed and netdate programs from the base tree. Setting 946 the time with these daemons has been obsolete for over a decade. 947 94820181126: 949 On amd64, arm64 and armv7 (architectures that install LLVM's ld.lld 950 linker as /usr/bin/ld) GNU ld is no longer installed as ld.bfd, as 951 it produces broken binaries when ifuncs are in use. Users needing 952 GNU ld should install the binutils port or package. 953 95420181123: 955 The BSD crtbegin and crtend code has been enabled by default. It has 956 had extensive testing on amd64, arm64, and i386. It can be disabled 957 by building a world with -DWITHOUT_BSD_CRTBEGIN. 958 95920181115: 960 The set of CTM commands (ctm, ctm_smail, ctm_rmail, ctm_dequeue) 961 has been converted to a port (misc/ctm) and will be removed from 962 FreeBSD-13. It is available as a package (ctm) for all supported 963 FreeBSD versions. 964 96520181110: 966 The default newsyslog.conf(5) file has been changed to only include 967 files in /etc/newsyslog.conf.d/ and /usr/local/etc/newsyslog.conf.d/ if 968 the filenames end in '.conf' and do not begin with a '.'. 969 970 You should check the configuration files in these two directories match 971 this naming convention. You can verify which configuration files are 972 being included using the command: 973 $ newsyslog -Nrv 974 97520181015: 976 Ports for the DRM modules have been simplified. Now, amd64 users should 977 just install the drm-kmod port. All others should install 978 drm-legacy-kmod. 979 980 Graphics hardware that's newer than about 2010 usually works with 981 drm-kmod. For hardware older than 2013, however, some users will need 982 to use drm-legacy-kmod if drm-kmod doesn't work for them. Hardware older 983 than 2008 usually only works in drm-legacy-kmod. The graphics team can 984 only commit to hardware made since 2013 due to the complexity of the 985 market and difficulty to test all the older cards effectively. If you 986 have hardware supported by drm-kmod, you are strongly encouraged to use 987 that as you will get better support. 988 989 Other than KPI chasing, drm-legacy-kmod will not be updated. As outlined 990 elsewhere, the drm and drm2 modules will be eliminated from the src base 991 soon (with a limited exception for arm). Please update to the package 992 asap and report any issues to [email protected]. 993 994 Generally, anybody using the drm*-kmod packages should add 995 WITHOUT_DRM_MODULE=t and WITHOUT_DRM2_MODULE=t to avoid nasty 996 cross-threading surprises, especially with automatic driver 997 loading from X11 startup. These will become the defaults in 13-current 998 shortly. 999 100020181012: 1001 The ixlv(4) driver has been renamed to iavf(4). As a consequence, 1002 custom kernel and module loading configuration files must be updated 1003 accordingly. Moreover, interfaces previous presented as ixlvN to the 1004 system are now exposed as iavfN and network configuration files must 1005 be adjusted as necessary. 1006 100720181009: 1008 OpenSSL has been updated to version 1.1.1. This update included 1009 additional various API changes throughout the base system. It is 1010 important to rebuild third-party software after upgrading. The value 1011 of __FreeBSD_version has been bumped accordingly. 1012 101320181006: 1014 The legacy DRM modules and drivers have now been added to the loader's 1015 module blacklist, in favor of loading them with kld_list in rc.conf(5). 1016 The module blacklist may be overridden with the loader.conf(5) 1017 'module_blacklist' variable, but loading them via rc.conf(5) is strongly 1018 encouraged. 1019 102020181002: 1021 The cam(4) based nda(4) driver will be used over nvd(4) by default on 1022 powerpc64. You may set 'options NVME_USE_NVD=1' in your kernel conf or 1023 loader tunable 'hw.nvme.use_nvd=1' if you wish to use the existing 1024 driver. Make sure to edit /boot/etc/kboot.conf and fstab to use the 1025 nda device name. 1026 102720180913: 1028 Reproducible build mode is now on by default, in preparation for 1029 FreeBSD 12.0. This eliminates build metadata such as the user, 1030 host, and time from the kernel (and uname), unless the working tree 1031 corresponds to a modified checkout from a version control system. 1032 The previous behavior can be obtained by setting the /etc/src.conf 1033 knob WITHOUT_REPRODUCIBLE_BUILD. 1034 103520180826: 1036 The Yarrow CSPRNG has been removed from the kernel as it has not been 1037 supported by its designers since at least 2003. Fortuna has been the 1038 default since FreeBSD-11. 1039 104020180822: 1041 devctl freeze/thaw have gone into the tree, the rc scripts have been 1042 updated to use them and devmatch has been changed. You should update 1043 kernel, userland and rc scripts all at the same time. 1044 104520180818: 1046 The default interpreter has been switched from 4th to Lua. 1047 LOADER_DEFAULT_INTERP, documented in build(7), will override the default 1048 interpreter. If you have custom FORTH code you will need to set 1049 LOADER_DEFAULT_INTERP=4th (valid values are 4th, lua or simp) in 1050 src.conf for the build. This will create default hard links between 1051 loader and loader_4th instead of loader and loader_lua, the new default. 1052 If you are using UEFI it will create the proper hard link to loader.efi. 1053 1054 bhyve uses userboot.so. It remains 4th-only until some issues are solved 1055 regarding coexisting with multiple versions of FreeBSD are resolved. 1056 105720180815: 1058 ls(1) now respects the COLORTERM environment variable used in other 1059 systems and software to indicate that a colored terminal is both 1060 supported and desired. If ls(1) is suddenly emitting colors, they may 1061 be disabled again by either removing the unwanted COLORTERM from your 1062 environment, or using `ls --color=never`. The ls(1) specific CLICOLOR 1063 may not be observed in a future release. 1064 106520180808: 1066 The default pager for most commands has been changed to "less". To 1067 restore the old behavior, set PAGER="more" and MANPAGER="more -s" in 1068 your environment. 1069 107020180731: 1071 The jedec_ts(4) driver has been removed. A superset of its functionality 1072 is available in the jedec_dimm(4) driver, and the manpage for that 1073 driver includes migration instructions. If you have "device jedec_ts" 1074 in your kernel configuration file, it must be removed. 1075 107620180730: 1077 amd64/GENERIC now has EFI runtime services, EFIRT, enabled by default. 1078 This should have no effect if the kernel is booted via BIOS/legacy boot. 1079 EFIRT may be disabled via a loader tunable, efi.rt.disabled, if a system 1080 has a buggy firmware that prevents a successful boot due to use of 1081 runtime services. 1082 108320180727: 1084 Atmel AT91RM9200 and AT91SAM9, Cavium CNS 11xx and XScale 1085 support has been removed from the tree. These ports were 1086 obsolete and/or known to be broken for many years. 1087 108820180723: 1089 loader.efi has been augmented to participate more fully in the 1090 UEFI boot manager protocol. loader.efi will now look at the 1091 BootXXXX environment variable to determine if a specific kernel 1092 or root partition was specified. XXXX is derived from BootCurrent. 1093 efibootmgr(8) manages these standard UEFI variables. 1094 109520180720: 1096 zfsloader's functionality has now been folded into loader. 1097 zfsloader is no longer necessary once you've updated your 1098 boot blocks. For a transition period, we will install a 1099 hardlink for zfsloader to loader to allow a smooth transition 1100 until the boot blocks can be updated (hard link because old 1101 zfs boot blocks don't understand symlinks). 1102 110320180719: 1104 ARM64 now have efifb support, if you want to have serial console 1105 on your arm64 board when an screen is connected and the bootloader 1106 setup a frame buffer for us to use, just add : 1107 boot_serial=YES 1108 boot_multicons=YES 1109 in /boot/loader.conf 1110 For Raspberry Pi 3 (RPI) users, this is needed even if you don't have 1111 an screen connected as the firmware will setup a frame buffer are that 1112 u-boot will expose as an EFI frame buffer. 1113 111420180719: 1115 New uid:gid added, ntpd:ntpd (123:123). Be sure to run mergemaster 1116 or take steps to update /etc/passwd before doing installworld on 1117 existing systems. Do not skip the "mergemaster -Fp" step before 1118 installworld, as described in the update procedures near the bottom 1119 of this document. Also, rc.d/ntpd now starts ntpd(8) as user ntpd 1120 if the new mac_ntpd(4) policy is available, unless ntpd_flags or 1121 the ntp config file contain options that change file/dir locations. 1122 When such options (e.g., "statsdir" or "crypto") are used, ntpd can 1123 still be run as non-root by setting ntpd_user=ntpd in rc.conf, after 1124 taking steps to ensure that all required files/dirs are accessible 1125 by the ntpd user. 1126 112720180717: 1128 Big endian arm support has been removed. 1129 113020180711: 1131 The static environment setup in kernel configs is no longer mutually 1132 exclusive with the loader(8) environment by default. In order to 1133 restore the previous default behavior of disabling the loader(8) 1134 environment if a static environment is present, you must specify 1135 loader_env.disabled=1 in the static environment. 1136 113720180705: 1138 The ABI of syscalls used by management tools like sockstat and 1139 netstat has been broken to allow 32-bit binaries to work on 1140 64-bit kernels without modification. These programs will need 1141 to match the kernel in order to function. External programs may 1142 require minor modifications to accommodate a change of type in 1143 structures from pointers to 64-bit virtual addresses. 1144 114520180702: 1146 On i386 and amd64 atomics are now inlined. Out of tree modules using 1147 atomics will need to be rebuilt. 1148 114920180701: 1150 The '%I' format in the kern.corefile sysctl limits the number of 1151 core files that a process can generate to the number stored in the 1152 debug.ncores sysctl. The '%I' format is replaced by the single digit 1153 index. Previously, if all indexes were taken the kernel would overwrite 1154 only a core file with the highest index in a filename. 1155 Currently the system will create a new core file if there is a free 1156 index or if all slots are taken it will overwrite the oldest one. 1157 115820180630: 1159 Clang, llvm, lld, lldb, compiler-rt and libc++ have been upgraded to 1160 6.0.1. Please see the 20141231 entry below for information about 1161 prerequisites and upgrading, if you are not already using clang 3.5.0 1162 or higher. 1163 116420180628: 1165 r335753 introduced a new quoting method. However, etc/devd/devmatch.conf 1166 needed to be changed to work with it. This change was made with r335763 1167 and requires a mergemaster / etcupdate / etc to update the installed 1168 file. 1169 117020180612: 1171 r334930 changed the interface between the NFS modules, so they all 1172 need to be rebuilt. r335018 did a __FreeBSD_version bump for this. 1173 117420180530: 1175 As of r334391 lld is the default amd64 system linker; it is installed 1176 as /usr/bin/ld. Kernel build workarounds (see 20180510 entry) are no 1177 longer necessary. 1178 117920180530: 1180 The kernel / userland interface for devinfo changed, so you'll 1181 need a new kernel and userland as a pair for it to work (rebuilding 1182 lib/libdevinfo is all that's required). devinfo and devmatch will 1183 not work, but everything else will when there's a mismatch. 1184 118520180523: 1186 The on-disk format for hwpmc callchain records has changed to include 1187 threadid corresponding to a given record. This changes the field offsets 1188 and thus requires that libpmcstat be rebuilt before using a kernel 1189 later than r334108. 1190 119120180517: 1192 The vxge(4) driver has been removed. This driver was introduced into 1193 HEAD one week before the Exar left the Ethernet market and is not 1194 known to be used. If you have device vxge in your kernel config file 1195 it must be removed. 1196 119720180510: 1198 The amd64 kernel now requires a ld that supports ifunc to produce a 1199 working kernel, either lld or a newer binutils. lld is built by default 1200 on amd64, and the 'buildkernel' target uses it automatically. However, 1201 it is not the default linker, so building the kernel the traditional 1202 way requires LD=ld.lld on the command line (or LD=/usr/local/bin/ld for 1203 binutils port/package). lld will soon be default, and this requirement 1204 will go away. 1205 1206 NOTE: As of r334391 lld is the default system linker on amd64, and no 1207 workaround is necessary. 1208 120920180508: 1210 The nxge(4) driver has been removed. This driver was for PCI-X 10g 1211 cards made by s2io/Neterion. The company was acquired by Exar and 1212 no longer sells or supports Ethernet products. If you have device 1213 nxge in your kernel config file it must be removed. 1214 121520180504: 1216 The tz database (tzdb) has been updated to 2018e. This version more 1217 correctly models time stamps in time zones with negative DST such as 1218 Europe/Dublin (from 1971 on), Europe/Prague (1946/7), and 1219 Africa/Windhoek (1994/2017). This does not affect the UT offsets, only 1220 time zone abbreviations and the tm_isdst flag. 1221 122220180502: 1223 The ixgb(4) driver has been removed. This driver was for an early and 1224 uncommon legacy PCI 10GbE for a single ASIC, Intel 82597EX. Intel 1225 quickly shifted to the long lived ixgbe family. If you have device 1226 ixgb in your kernel config file it must be removed. 1227 122820180501: 1229 The lmc(4) driver has been removed. This was a WAN interface 1230 card that was already reportedly rare in 2003, and had an ambiguous 1231 license. If you have device lmc in your kernel config file it must 1232 be removed. 1233 123420180413: 1235 Support for Arcnet networks has been removed. If you have device 1236 arcnet or device cm in your kernel config file they must be 1237 removed. 1238 123920180411: 1240 Support for FDDI networks has been removed. If you have device 1241 fddi or device fpa in your kernel config file they must be 1242 removed. 1243 124420180406: 1245 In addition to supporting RFC 3164 formatted messages, the 1246 syslogd(8) service is now capable of parsing RFC 5424 formatted 1247 log messages. The main benefit of using RFC 5424 is that clients 1248 may now send log messages with timestamps containing year numbers, 1249 microseconds and time zone offsets. 1250 1251 Similarly, the syslog(3) C library function has been altered to 1252 send RFC 5424 formatted messages to the local system logging 1253 daemon. On systems using syslogd(8), this change should have no 1254 negative impact, as long as syslogd(8) and the C library are 1255 updated at the same time. On systems using a different system 1256 logging daemon, it may be necessary to make configuration 1257 adjustments, depending on the software used. 1258 1259 When using syslog-ng, add the 'syslog-protocol' flag to local 1260 input sources to enable parsing of RFC 5424 formatted messages: 1261 1262 source src { 1263 unix-dgram("/var/run/log" flags(syslog-protocol)); 1264 } 1265 1266 When using rsyslog, disable the 'SysSock.UseSpecialParser' option 1267 of the 'imuxsock' module to let messages be processed by the 1268 regular RFC 3164/5424 parsing pipeline: 1269 1270 module(load="imuxsock" SysSock.UseSpecialParser="off") 1271 1272 Do note that these changes only affect communication between local 1273 applications and syslogd(8). The format that syslogd(8) uses to 1274 store messages on disk or forward messages to other systems 1275 remains unchanged. syslogd(8) still uses RFC 3164 for these 1276 purposes. Options to customize this behaviour will be added in the 1277 future. Utilities that process log files stored in /var/log are 1278 thus expected to continue to function as before. 1279 1280 __FreeBSD_version has been incremented to 1200061 to denote this 1281 change. 1282 128320180328: 1284 Support for token ring networks has been removed. If you 1285 have "device token" in your kernel config you should remove 1286 it. No device drivers supported token ring. 1287 128820180323: 1289 makefs was modified to be able to tag ISO9660 El Torito boot catalog 1290 entries as EFI instead of overloading the i386 tag as done previously. 1291 The amd64 mkisoimages.sh script used to build amd64 ISO images for 1292 release was updated to use this. This may mean that makefs must be 1293 updated before "make cdrom" can be run in the release directory. This 1294 should be as simple as: 1295 1296 $ cd $SRCDIR/usr.sbin/makefs 1297 $ make depend all install 1298 129920180212: 1300 FreeBSD boot loader enhanced with Lua scripting. It's purely opt-in for 1301 now by building WITH_LOADER_LUA and WITHOUT_FORTH in /etc/src.conf. 1302 Co-existence for the transition period will come shortly. Booting is a 1303 complex environment and test coverage for Lua-enabled loaders has been 1304 thin, so it would be prudent to assume it might not work and make 1305 provisions for backup boot methods. 1306 130720180211: 1308 devmatch functionality has been turned on in devd. It will automatically 1309 load drivers for unattached devices. This may cause unexpected drivers 1310 to be loaded. Please report any problems to current@ and 1311 [email protected]. 1312 131320180114: 1314 Clang, llvm, lld, lldb, compiler-rt and libc++ have been upgraded to 1315 6.0.0. Please see the 20141231 entry below for information about 1316 prerequisites and upgrading, if you are not already using clang 3.5.0 1317 or higher. 1318 131920180110: 1320 LLVM's lld linker is now used as the FreeBSD/amd64 bootstrap linker. 1321 This means it is used to link the kernel and userland libraries and 1322 executables, but is not yet installed as /usr/bin/ld by default. 1323 1324 To revert to ld.bfd as the bootstrap linker, in /etc/src.conf set 1325 WITHOUT_LLD_BOOTSTRAP=yes 1326 132720180110: 1328 On i386, pmtimer has been removed. Its functionality has been folded 1329 into apm. It was a no-op on ACPI in current for a while now (but was 1330 still needed on i386 in FreeBSD 11 and earlier). Users may need to 1331 remove it from kernel config files. 1332 133320180104: 1334 The use of RSS hash from the network card aka flowid has been 1335 disabled by default for lagg(4) as it's currently incompatible with 1336 the lacp and loadbalance protocols. 1337 1338 This can be re-enabled by setting the following in loader.conf: 1339 net.link.lagg.default_use_flowid="1" 1340 134120180102: 1342 The SW_WATCHDOG option is no longer necessary to enable the 1343 hardclock-based software watchdog if no hardware watchdog is 1344 configured. As before, SW_WATCHDOG will cause the software 1345 watchdog to be enabled even if a hardware watchdog is configured. 1346 134720171215: 1348 r326887 fixes the issue described in the 20171214 UPDATING entry. 1349 r326888 flips the switch back to building GELI support always. 1350 135120171214: 1352 r362593 broke ZFS + GELI support for reasons unknown. However, 1353 it also broke ZFS support generally, so GELI has been turned off 1354 by default as the lesser evil in r326857. If you boot off ZFS and/or 1355 GELI, it might not be a good time to update. 1356 135720171125: 1358 PowerPC users must update loader(8) by rebuilding world before 1359 installing a new kernel, as the protocol connecting them has 1360 changed. Without the update, loader metadata will not be passed 1361 successfully to the kernel and users will have to enter their 1362 root partition at the kernel mountroot prompt to continue booting. 1363 Newer versions of loader can boot old kernels without issue. 1364 136520171110: 1366 The LOADER_FIREWIRE_SUPPORT build variable has been renamed to 1367 WITH/OUT_LOADER_FIREWIRE. LOADER_{NO_,}GELI_SUPPORT has been renamed 1368 to WITH/OUT_LOADER_GELI. 1369 137020171106: 1371 The naive and non-compliant support of posix_fallocate(2) in ZFS 1372 has been removed as of r325320. The system call now returns EINVAL 1373 when used on a ZFS file. Although the new behavior complies with the 1374 standard, some consumers are not prepared to cope with it. 1375 One known victim is lld prior to r325420. 1376 137720171102: 1378 Building in a FreeBSD src checkout will automatically create object 1379 directories now rather than store files in the current directory if 1380 'make obj' was not ran. Calling 'make obj' is no longer necessary. 1381 This feature can be disabled by setting WITHOUT_AUTO_OBJ=yes in 1382 /etc/src-env.conf (not /etc/src.conf), or passing the option in the 1383 environment. 1384 138520171101: 1386 The default MAKEOBJDIR has changed from /usr/obj/<srcdir> for native 1387 builds, and /usr/obj/<arch>/<srcdir> for cross-builds, to a unified 1388 /usr/obj/<srcdir>/<arch>. This behavior can be changed to the old 1389 format by setting WITHOUT_UNIFIED_OBJDIR=yes in /etc/src-env.conf, 1390 the environment, or with -DWITHOUT_UNIFIED_OBJDIR when building. 1391 The UNIFIED_OBJDIR option is a transitional feature that will be 1392 removed for 12.0 release; please migrate to the new format for any 1393 tools by looking up the OBJDIR used by 'make -V .OBJDIR' means rather 1394 than hardcoding paths. 1395 139620171028: 1397 The native-xtools target no longer installs the files by default to the 1398 OBJDIR. Use the native-xtools-install target with a DESTDIR to install 1399 to ${DESTDIR}/${NXTP} where NXTP defaults to /nxb-bin. 1400 140120171021: 1402 As part of the boot loader infrastructure cleanup, LOADER_*_SUPPORT 1403 options are changing from controlling the build if defined / undefined 1404 to controlling the build with explicit 'yes' or 'no' values. They will 1405 shift to WITH/WITHOUT options to match other options in the system. 1406 140720171010: 1408 libstand has turned into a private library for sys/boot use only. 1409 It is no longer supported as a public interface outside of sys/boot. 1410 141120171005: 1412 The arm port has split armv6 into armv6 and armv7. armv7 is now 1413 a valid TARGET_ARCH/MACHINE_ARCH setting. If you have an armv7 system 1414 and are running a kernel from before r324363, you will need to add 1415 MACHINE_ARCH=armv7 to 'make buildworld' to do a native build. 1416 141720171003: 1418 When building multiple kernels using KERNCONF, non-existent KERNCONF 1419 files will produce an error and buildkernel will fail. Previously 1420 missing KERNCONF files silently failed giving no indication as to 1421 why, only to subsequently discover during installkernel that the 1422 desired kernel was never built in the first place. 1423 142420170912: 1425 The default serial number format for CTL LUNs has changed. This will 1426 affect users who use /dev/diskid/* device nodes, or whose FibreChannel 1427 or iSCSI clients care about their LUNs' serial numbers. Users who 1428 require serial number stability should hardcode serial numbers in 1429 /etc/ctl.conf . 1430 143120170912: 1432 For 32-bit arm compiled for hard-float support, soft-floating point 1433 binaries now always get their shared libraries from 1434 LD_SOFT_LIBRARY_PATH (in the past, this was only used if 1435 /usr/libsoft also existed). Only users with a hard-float ld.so, but 1436 soft-float everything else should be affected. 1437 143820170826: 1439 The geli password typed at boot is now hidden. To restore the previous 1440 behavior, see geli(8) for configuration options. 1441 144220170825: 1443 Move PMTUD blackhole counters to TCPSTATS and remove them from bare 1444 sysctl values. Minor nit, but requires a rebuild of both world/kernel 1445 to complete. 1446 144720170814: 1448 "make check" behavior (made in ^/head@r295380) has been changed to 1449 execute from a limited sandbox, as opposed to executing from 1450 ${TESTSDIR}. 1451 1452 Behavioral changes: 1453 - The "beforecheck" and "aftercheck" targets are now specified. 1454 - ${CHECKDIR} (added in commit noted above) has been removed. 1455 - Legacy behavior can be enabled by setting 1456 WITHOUT_MAKE_CHECK_USE_SANDBOX in src.conf(5) or the environment. 1457 1458 If the limited sandbox mode is enabled, "make check" will execute 1459 "make distribution", then install, execute the tests, and clean up the 1460 sandbox if successful. 1461 1462 The "make distribution" and "make install" targets are typically run as 1463 root to set appropriate permissions and ownership at installation time. 1464 The end-user should set "WITH_INSTALL_AS_USER" in src.conf(5) or the 1465 environment if executing "make check" with limited sandbox mode using 1466 an unprivileged user. 1467 146820170808: 1469 Since the switch to GPT disk labels, fsck for UFS/FFS has been 1470 unable to automatically find alternate superblocks. As of r322297, 1471 the information needed to find alternate superblocks has been 1472 moved to the end of the area reserved for the boot block. 1473 Filesystems created with a newfs of this vintage or later 1474 will create the recovery information. If you have a filesystem 1475 created prior to this change and wish to have a recovery block 1476 created for your filesystem, you can do so by running fsck in 1477 foreground mode (i.e., do not use the -p or -y options). As it 1478 starts, fsck will ask ``SAVE DATA TO FIND ALTERNATE SUPERBLOCKS'' 1479 to which you should answer yes. 1480 148120170728: 1482 As of r321665, an NFSv4 server configuration that services 1483 Kerberos mounts or clients that do not support the uid/gid in 1484 owner/owner_group string capability, must explicitly enable 1485 the nfsuserd daemon by adding nfsuserd_enable="YES" to the 1486 machine's /etc/rc.conf file. 1487 148820170722: 1489 Clang, llvm, lldb, compiler-rt and libc++ have been upgraded to 5.0.0. 1490 Please see the 20141231 entry below for information about prerequisites 1491 and upgrading, if you are not already using clang 3.5.0 or higher. 1492 149320170701: 1494 WITHOUT_RCMDS is now the default. Set WITH_RCMDS if you need the 1495 r-commands (rlogin, rsh, etc.) to be built with the base system. 1496 149720170625: 1498 The FreeBSD/powerpc platform now uses a 64-bit type for time_t. This is 1499 a very major ABI incompatible change, so users of FreeBSD/powerpc must 1500 be careful when performing source upgrades. It is best to run 1501 'make installworld' from an alternate root system, either a live 1502 CD/memory stick, or a temporary root partition. Additionally, all ports 1503 must be recompiled. powerpc64 is largely unaffected, except in the case 1504 of 32-bit compatibility. All 32-bit binaries will be affected. 1505 150620170623: 1507 Forward compatibility for the "ino64" project have been committed. This 1508 will allow most new binaries to run on older kernels in a limited 1509 fashion. This prevents many of the common foot-shooting actions in the 1510 upgrade as well as the limited ability to roll back the kernel across 1511 the ino64 upgrade. Complicated use cases may not work properly, though 1512 enough simpler ones work to allow recovery in most situations. 1513 151420170620: 1515 Switch back to the BSDL dtc (Device Tree Compiler). Set WITH_GPL_DTC 1516 if you require the GPL compiler. 1517 151820170618: 1519 The internal ABI used for communication between the NFS kernel modules 1520 was changed by r320085, so __FreeBSD_version was bumped to 1521 ensure all the NFS related modules are updated together. 1522 152320170617: 1524 The ABI of struct event was changed by extending the data 1525 member to 64bit and adding ext fields. For upgrade, same 1526 precautions as for the entry 20170523 "ino64" must be 1527 followed. 1528 152920170531: 1530 The GNU roff toolchain has been removed from base. To render manpages 1531 which are not supported by mandoc(1), man(1) can fallback on GNU roff 1532 from ports (and recommends to install it). 1533 To render roff(7) documents, consider using GNU roff from ports or the 1534 heirloom doctools roff toolchain from ports via pkg install groff or 1535 via pkg install heirloom-doctools. 1536 153720170524: 1538 The ath(4) and ath_hal(4) modules now build piecemeal to allow for 1539 smaller runtime footprint builds. This is useful for embedded systems 1540 which only require one chipset support. 1541 1542 If you load it as a module, make sure this is in /boot/loader.conf: 1543 1544 if_ath_load="YES" 1545 1546 This will load the HAL, all chip/RF backends and if_ath_pci. 1547 If you have if_ath_pci in /boot/loader.conf, ensure it is after 1548 if_ath or it will not load any HAL chipset support. 1549 1550 If you want to selectively load things (eg on cheaper ARM/MIPS 1551 platforms where RAM is at a premium) you should: 1552 1553 * load ath_hal 1554 * load the chip modules in question 1555 * load ath_rate, ath_dfs 1556 * load ath_main 1557 * load if_ath_pci and/or if_ath_ahb depending upon your particular 1558 bus bind type - this is where probe/attach is done. 1559 1560 For further comments/feedback, poke adrian@ . 1561 156220170523: 1563 The "ino64" 64-bit inode project has been committed, which extends 1564 a number of types to 64 bits. Upgrading in place requires care and 1565 adherence to the documented upgrade procedure. 1566 1567 If using a custom kernel configuration ensure that the 1568 COMPAT_FREEBSD11 option is included (as during the upgrade the 1569 system will be running the ino64 kernel with the existing world). 1570 1571 For the safest in-place upgrade begin by removing previous build 1572 artifacts via "rm -rf /usr/obj/*". Then, carefully follow the full 1573 procedure documented below under the heading "To rebuild everything and 1574 install it on the current system." Specifically, a reboot is required 1575 after installing the new kernel before installing world. While an 1576 installworld normally works by accident from multiuser after rebooting 1577 the proper kernel, there are many cases where this will fail across this 1578 upgrade and installworld from single user is required. 1579 158020170424: 1581 The NATM framework including the en(4), fatm(4), hatm(4), and 1582 patm(4) devices has been removed. Consumers should plan a 1583 migration before the end-of-life date for FreeBSD 11. 1584 158520170420: 1586 GNU diff has been replaced by a BSD licensed diff. Some features of GNU 1587 diff has not been implemented, if those are needed a newer version of 1588 GNU diff is available via the diffutils package under the gdiff name. 1589 159020170413: 1591 As of r316810 for ipfilter, keep frags is no longer assumed when 1592 keep state is specified in a rule. r316810 aligns ipfilter with 1593 documentation in man pages separating keep frags from keep state. 1594 This allows keep state to be specified without forcing keep frags 1595 and allows keep frags to be specified independently of keep state. 1596 To maintain previous behaviour, also specify keep frags with 1597 keep state (as documented in ipf.conf.5). 1598 159920170407: 1600 arm64 builds now use the base system LLD 4.0.0 linker by default, 1601 instead of requiring that the aarch64-binutils port or package be 1602 installed. To continue using aarch64-binutils, set 1603 CROSS_BINUTILS_PREFIX=/usr/local/aarch64-freebsd/bin . 1604 160520170405: 1606 The UDP optimization in entry 20160818 that added the sysctl 1607 net.inet.udp.require_l2_bcast has been reverted. L2 broadcast 1608 packets will no longer be treated as L3 broadcast packets. 1609 161020170331: 1611 Binds and sends to the loopback addresses, IPv6 and IPv4, will now 1612 use any explicitly assigned loopback address available in the jail 1613 instead of using the first assigned address of the jail. 1614 161520170329: 1616 The ctl.ko module no longer implements the iSCSI target frontend: 1617 cfiscsi.ko does instead. 1618 1619 If building cfiscsi.ko as a kernel module, the module can be loaded 1620 via one of the following methods: 1621 - `cfiscsi_load="YES"` in loader.conf(5). 1622 - Add `cfiscsi` to `$kld_list` in rc.conf(5). 1623 - ctladm(8)/ctld(8), when compiled with iSCSI support 1624 (`WITH_ISCSI=yes` in src.conf(5)) 1625 1626 Please see cfiscsi(4) for more details. 1627 162820170316: 1629 The mmcsd.ko module now additionally depends on geom_flashmap.ko. 1630 Also, mmc.ko and mmcsd.ko need to be a matching pair built from the 1631 same source (previously, the dependency of mmcsd.ko on mmc.ko was 1632 missing, but mmcsd.ko now will refuse to load if it is incompatible 1633 with mmc.ko). 1634 163520170315: 1636 The syntax of ipfw(8) named states was changed to avoid ambiguity. 1637 If you have used named states in the firewall rules, you need to modify 1638 them after installworld and before rebooting. Now named states must 1639 be prefixed with colon. 1640 164120170311: 1642 The old drm (sys/dev/drm/) drivers for i915 and radeon have been 1643 removed as the userland we provide cannot use them. The KMS version 1644 (sys/dev/drm2) supports the same hardware. 1645 164620170302: 1647 Clang, llvm, lldb, compiler-rt and libc++ have been upgraded to 4.0.0. 1648 Please see the 20141231 entry below for information about prerequisites 1649 and upgrading, if you are not already using clang 3.5.0 or higher. 1650 165120170221: 1652 The code that provides support for ZFS .zfs/ directory functionality 1653 has been reimplemented. It's not possible now to create a snapshot 1654 by mkdir under .zfs/snapshot/. That should be the only user visible 1655 change. 1656 165720170216: 1658 EISA bus support has been removed. The WITH_EISA option is no longer 1659 valid. 1660 166120170215: 1662 MCA bus support has been removed. 1663 166420170127: 1665 The WITH_LLD_AS_LD / WITHOUT_LLD_AS_LD build knobs have been renamed 1666 WITH_LLD_IS_LD / WITHOUT_LLD_IS_LD, for consistency with CLANG_IS_CC. 1667 166820170112: 1669 The EM_MULTIQUEUE kernel configuration option is deprecated now that 1670 the em(4) driver conforms to iflib specifications. 1671 167220170109: 1673 The igb(4), em(4) and lem(4) ethernet drivers are now implemented via 1674 IFLIB. If you have a custom kernel configuration that excludes em(4) 1675 but you use igb(4), you need to re-add em(4) to your custom 1676 configuration. 1677 167820161217: 1679 Clang, llvm, lldb, compiler-rt and libc++ have been upgraded to 3.9.1. 1680 Please see the 20141231 entry below for information about prerequisites 1681 and upgrading, if you are not already using clang 3.5.0 or higher. 1682 168320161124: 1684 Clang, llvm, lldb, compiler-rt and libc++ have been upgraded to 3.9.0. 1685 Please see the 20141231 entry below for information about prerequisites 1686 and upgrading, if you are not already using clang 3.5.0 or higher. 1687 168820161119: 1689 The layout of the pmap structure has changed for powerpc to put the pmap 1690 statistics at the front for all CPU variations. libkvm(3) and all tools 1691 that link against it need to be recompiled. 1692 169320161030: 1694 isl(4) and cyapa(4) drivers now require a new driver, 1695 chromebook_platform(4), to work properly on Chromebook-class hardware. 1696 On other types of hardware the drivers may need to be configured using 1697 device hints. Please see the corresponding manual pages for details. 1698 169920161017: 1700 The urtwn(4) driver was merged into rtwn(4) and now consists of 1701 rtwn(4) main module + rtwn_usb(4) and rtwn_pci(4) bus-specific 1702 parts. 1703 Also, firmware for RTL8188CE was renamed due to possible name 1704 conflict (rtwnrtl8192cU(B) -> rtwnrtl8192cE(B)) 1705 170620161015: 1707 GNU rcs has been removed from base. It is available as packages: 1708 - rcs: Latest GPLv3 GNU rcs version. 1709 - rcs57: Copy of the latest version of GNU rcs (GPLv2) before it was 1710 removed from base. 1711 171220161008: 1713 Use of the cc_cdg, cc_chd, cc_hd, or cc_vegas congestion control 1714 modules now requires that the kernel configuration contain the 1715 TCP_HHOOK option. (This option is included in the GENERIC kernel.) 1716 171720161003: 1718 The WITHOUT_ELFCOPY_AS_OBJCOPY src.conf(5) knob has been retired. 1719 ELF Tool Chain's elfcopy is always installed as /usr/bin/objcopy. 1720 172120160924: 1722 Relocatable object files with the extension of .So have been renamed 1723 to use an extension of .pico instead. The purpose of this change is 1724 to avoid a name clash with shared libraries on case-insensitive file 1725 systems. On those file systems, foo.So is the same file as foo.so. 1726 172720160918: 1728 GNU rcs has been turned off by default. It can (temporarily) be built 1729 again by adding WITH_RCS knob in src.conf. 1730 Otherwise, GNU rcs is available from packages: 1731 - rcs: Latest GPLv3 GNU rcs version. 1732 - rcs57: Copy of the latest version of GNU rcs (GPLv2) from base. 1733 173420160918: 1735 The backup_uses_rcs functionality has been removed from rc.subr. 1736 173720160908: 1738 The queue(3) debugging macro, QUEUE_MACRO_DEBUG, has been split into 1739 two separate components, QUEUE_MACRO_DEBUG_TRACE and 1740 QUEUE_MACRO_DEBUG_TRASH. Define both for the original 1741 QUEUE_MACRO_DEBUG behavior. 1742 174320160824: 1744 r304787 changed some ioctl interfaces between the iSCSI userspace 1745 programs and the kernel. ctladm, ctld, iscsictl, and iscsid must be 1746 rebuilt to work with new kernels. __FreeBSD_version has been bumped 1747 to 1200005. 1748 174920160818: 1750 The UDP receive code has been updated to only treat incoming UDP 1751 packets that were addressed to an L2 broadcast address as L3 1752 broadcast packets. It is not expected that this will affect any 1753 standards-conforming UDP application. The new behaviour can be 1754 disabled by setting the sysctl net.inet.udp.require_l2_bcast to 1755 0. 1756 175720160818: 1758 Remove the openbsd_poll system call. 1759 __FreeBSD_version has been bumped because of this. 1760 176120160708: 1762 The stable/11 branch has been created from head@r302406. 1763 1764After branch N is created, entries older than the N-2 branch point are removed 1765from this file. After stable/14 is branched and current becomes FreeBSD 15, 1766entries older than stable/12 branch point will be removed from current's 1767UPDATING file. 1768 1769COMMON ITEMS: 1770 1771 General Notes 1772 ------------- 1773 Sometimes, obscure build problems are the result of environment 1774 poisoning. This can happen because the make utility reads its 1775 environment when searching for values for global variables. To run 1776 your build attempts in an "environmental clean room", prefix all make 1777 commands with 'env -i '. See the env(1) manual page for more details. 1778 Occasionally a build failure will occur with "make -j" due to a race 1779 condition. If this happens try building again without -j, and please 1780 report a bug if it happens consistently. 1781 1782 When upgrading from one major version to another it is generally best to 1783 upgrade to the latest code in the currently installed branch first, then 1784 do an upgrade to the new branch. This is the best-tested upgrade path, 1785 and has the highest probability of being successful. Please try this 1786 approach if you encounter problems with a major version upgrade. Since 1787 the stable 4.x branch point, one has generally been able to upgrade from 1788 anywhere in the most recent stable branch to head / current (or even the 1789 last couple of stable branches). See the top of this file when there's 1790 an exception. 1791 1792 The update process will emit an error on an attempt to perform a build 1793 or install from a FreeBSD version below the earliest supported version. 1794 When updating from an older version the update should be performed one 1795 major release at a time, including running `make delete-old` at each 1796 step. 1797 1798 When upgrading a live system, having a root shell around before 1799 installing anything can help undo problems. Not having a root shell 1800 around can lead to problems if pam has changed too much from your 1801 starting point to allow continued authentication after the upgrade. 1802 1803 This file should be read as a log of events. When a later event changes 1804 information of a prior event, the prior event should not be deleted. 1805 Instead, a pointer to the entry with the new information should be 1806 placed in the old entry. Readers of this file should also sanity check 1807 older entries before relying on them blindly. Authors of new entries 1808 should write them with this in mind. 1809 1810 ZFS notes 1811 --------- 1812 When upgrading the boot ZFS pool to a new version (via zpool upgrade), 1813 always follow these three steps: 1814 1815 1) recompile and reinstall the ZFS boot loader and boot block 1816 (this is part of "make buildworld" and "make installworld") 1817 1818 2) update the ZFS boot block on your boot drive (only required when 1819 doing a zpool upgrade): 1820 1821 When booting on x86 via BIOS, use the following to update the ZFS boot 1822 block on the freebsd-boot partition of a GPT partitioned drive ada0: 1823 gpart bootcode -p /boot/gptzfsboot -i $N ada0 1824 The value $N will typically be 1. For EFI booting, see EFI notes. 1825 1826 3) zpool upgrade the root pool. New bootblocks will work with old 1827 pools, but not vice versa, so they need to be updated before any 1828 zpool upgrade. 1829 1830 Non-boot pools do not need these updates. 1831 1832 EFI notes 1833 --------- 1834 1835 There are two locations the boot loader can be installed into. The 1836 current location (and the default) is \efi\freebsd\loader.efi and using 1837 efibootmgr(8) to configure it. The old location, that must be used on 1838 deficient systems that don't honor efibootmgr(8) protocols, is the 1839 fallback location of \EFI\BOOT\BOOTxxx.EFI. Generally, you will copy 1840 /boot/loader.efi to this location, but on systems installed a long time 1841 ago the ESP may be too small and /boot/boot1.efi may be needed unless 1842 the ESP has been expanded in the meantime. 1843 1844 Recent systems will have the ESP mounted on /boot/efi, but older ones 1845 may not have it mounted at all, or mounted in a different 1846 location. Older arm SD images with MBR used /boot/msdos as the 1847 mountpoint. The ESP is a MSDOS filesystem. 1848 1849 The EFI boot loader rarely needs to be updated. For ZFS booting, 1850 however, you must update loader.efi before you do 'zpool upgrade' the 1851 root zpool, otherwise the old loader.efi may reject the upgraded zpool 1852 since it does not automatically understand some new features. 1853 1854 See loader.efi(8) and uefi(8) for more details. 1855 1856 To build a kernel 1857 ----------------- 1858 If you are updating from a prior version of FreeBSD (even one just 1859 a few days old), you should follow this procedure. It is the most 1860 failsafe as it uses a /usr/obj tree with a fresh mini-buildworld, 1861 1862 make kernel-toolchain 1863 make -DALWAYS_CHECK_MAKE buildkernel KERNCONF=YOUR_KERNEL_HERE 1864 make -DALWAYS_CHECK_MAKE installkernel KERNCONF=YOUR_KERNEL_HERE 1865 1866 To test a kernel once 1867 --------------------- 1868 If you just want to boot a kernel once (because you are not sure 1869 if it works, or if you want to boot a known bad kernel to provide 1870 debugging information) run 1871 make installkernel KERNCONF=YOUR_KERNEL_HERE KODIR=/boot/testkernel 1872 nextboot -k testkernel 1873 1874 To rebuild everything and install it on the current system. 1875 ----------------------------------------------------------- 1876 # Note: sometimes if you are running current you gotta do more than 1877 # is listed here if you are upgrading from a really old current. 1878 1879 <make sure you have good level 0 dumps> 1880 make buildworld 1881 make buildkernel KERNCONF=YOUR_KERNEL_HERE 1882 make installkernel KERNCONF=YOUR_KERNEL_HERE 1883 [1] 1884 <reboot in single user> [3] 1885 etcupdate -p [5] 1886 make installworld 1887 etcupdate -B [4] 1888 make delete-old [6] 1889 <reboot> 1890 1891 To cross-install current onto a separate partition 1892 -------------------------------------------------- 1893 # In this approach we use a separate partition to hold 1894 # current's root, 'usr', and 'var' directories. A partition 1895 # holding "/", "/usr" and "/var" should be about 2GB in 1896 # size. 1897 1898 <make sure you have good level 0 dumps> 1899 <boot into -stable> 1900 make buildworld 1901 make buildkernel KERNCONF=YOUR_KERNEL_HERE 1902 <maybe newfs current's root partition> 1903 <mount current's root partition on directory ${CURRENT_ROOT}> 1904 make installworld DESTDIR=${CURRENT_ROOT} -DDB_FROM_SRC 1905 make distribution DESTDIR=${CURRENT_ROOT} # if newfs'd 1906 make installkernel KERNCONF=YOUR_KERNEL_HERE DESTDIR=${CURRENT_ROOT} 1907 cp /etc/fstab ${CURRENT_ROOT}/etc/fstab # if newfs'd 1908 <edit ${CURRENT_ROOT}/etc/fstab to mount "/" from the correct partition> 1909 <reboot into current> 1910 <do a "native" rebuild/install as described in the previous section> 1911 <maybe install compatibility libraries from ports/misc/compat*> 1912 <reboot> 1913 1914 1915 To upgrade in-place from stable to current 1916 ---------------------------------------------- 1917 <make sure you have good level 0 dumps> 1918 make buildworld [9] 1919 make buildkernel KERNCONF=YOUR_KERNEL_HERE [8] 1920 make installkernel KERNCONF=YOUR_KERNEL_HERE 1921 [1] 1922 <reboot in single user> [3] 1923 etcupdate -p [5] 1924 make installworld 1925 etcupdate -B [4] 1926 make delete-old [6] 1927 <reboot> 1928 1929 Make sure that you've read the UPDATING file to understand the 1930 tweaks to various things you need. At this point in the life 1931 cycle of current, things change often and you are on your own 1932 to cope. The defaults can also change, so please read ALL of 1933 the UPDATING entries. 1934 1935 Also, if you are tracking -current, you must be subscribed to 1936 [email protected]. Make sure that before you update 1937 your sources that you have read and understood all the recent 1938 messages there. If in doubt, please track -stable which has 1939 much fewer pitfalls. 1940 1941 [1] If you have third party modules, such as vmware, you should disable 1942 them at this point so they don't crash your system on 1943 reboot. Alternatively, you should rebuild all the modules you have in 1944 your system and install them as well. If you are running -current, you 1945 should seriously consider placing all sources to all the modules for 1946 your system (or symlinks to them) in /usr/local/sys/modules so this 1947 happens automatically. If all your modules come from ports, then adding 1948 the port origin directories to PORTS_MODULES instead is also automatic 1949 and effective, eg: 1950 PORTS_MODULES+=x11/nvidia-driver 1951 1952 [3] From the bootblocks, boot -s, and then do 1953 fsck -p 1954 mount -u / 1955 mount -a 1956 sh /etc/rc.d/zfs start # mount zfs filesystem, if needed 1957 cd src # full path to source 1958 adjkerntz -i # if CMOS is wall time 1959 Also, when doing a major release upgrade, it is required that you boot 1960 into single user mode to do the installworld. 1961 1962 [4] Note: This step is non-optional. Failure to do this step 1963 can result in a significant reduction in the functionality of the 1964 system. Attempting to do it by hand is not recommended and those 1965 that pursue this avenue should read this file carefully, as well 1966 as the archives of freebsd-current and freebsd-hackers mailing lists 1967 for potential gotchas. See etcupdate(8) for more information. 1968 1969 [5] Usually this step is a no-op. However, from time to time 1970 you may need to do this if you get unknown user in the following 1971 step. 1972 1973 [6] This only deletes old files and directories. Old libraries 1974 can be deleted by "make delete-old-libs", but you have to make 1975 sure that no program is using those libraries anymore. 1976 1977 [8] The new kernel must be able to run existing binaries used by an 1978 installworld. When upgrading across major versions, the new kernel's 1979 configuration must include the correct COMPAT_FREEBSD<n> option for 1980 existing binaries (e.g. COMPAT_FREEBSD11 to run 11.x binaries). Failure 1981 to do so may leave you with a system that is hard to boot to recover. A 1982 GENERIC kernel will include suitable compatibility options to run 1983 binaries from older branches. Note that the ability to run binaries 1984 from unsupported branches is not guaranteed. 1985 1986 Make sure that you merge any new devices from GENERIC since the 1987 last time you updated your kernel config file. Options also 1988 change over time, so you may need to adjust your custom kernels 1989 for these as well. 1990 1991 [9] If CPUTYPE is defined in your /etc/make.conf, make sure to use the 1992 "?=" instead of the "=" assignment operator, so that buildworld can 1993 override the CPUTYPE if it needs to. 1994 1995 MAKEOBJDIRPREFIX must be defined in an environment variable, and 1996 not on the command line, or in /etc/make.conf. buildworld will 1997 warn if it is improperly defined. 1998FORMAT: 1999 2000This file contains a list, in reverse chronological order, of major 2001breakages in tracking -current. It is not guaranteed to be a complete 2002list of such breakages, and only contains entries since September 23, 2011. 2003If you need to see UPDATING entries from before that date, you will need 2004to fetch an UPDATING file from an older FreeBSD release. 2005 2006Copyright information: 2007 2008Copyright 1998-2009 M.
