1Updating Information for users of FreeBSD-CURRENT. 2 3This file is maintained and copyrighted by M. Warner Losh <imp@freebsd.org>. 4See end of file for further details. For commonly done items, please see the 5COMMON ITEMS: section later in the file. These instructions assume that you 6basically know what you are doing. If not, then please consult the FreeBSD 7handbook: 8 9 https://docs.freebsd.org/en/books/handbook/cutting-edge/#makeworld 10 11Items affecting the ports and packages system can be found in 12/usr/ports/UPDATING. Please read that file before updating system packages 13and/or ports. 14 15NOTE TO PEOPLE WHO THINK THAT FreeBSD 15.x IS SLOW: 16 FreeBSD 15.x has many debugging features turned on, in both the kernel 17 and userland. These features attempt to detect incorrect use of 18 system primitives, and encourage loud failure through extra sanity 19 checking and fail stop semantics. They also substantially impact 20 system performance. If you want to do performance measurement, 21 benchmarking, and optimization, you'll want to turn them off. This 22 includes various WITNESS- related kernel options, INVARIANTS, malloc 23 debugging flags in userland, and various verbose features in the 24 kernel. Many developers choose to disable these features on build 25 machines to maximize performance. (To completely disable malloc 26 debugging, define WITH_MALLOC_PRODUCTION in /etc/src.conf and rebuild 27 world, or to merely disable the most expensive debugging functionality 28 at runtime, run "ln -s 'abort:false,junk:false' /etc/malloc.conf".) 29 3020230927: 31 The EARLY_AP_STARTUP kernel option is mandatory on x86. The option 32 has been added to DEFAULTS, so it should automatically be included in 33 custom kernel configurations without any additional change. 34 3520230922: 36 A new loader tunable net.pf.default_to_drop allows pf(4)’s default 37 behaviour to be changed from pass to drop. Previously this required 38 recompiling the kernel with the option PF_DEFAULT_TO_DROP. 39 4020230914: 41 Enable splitting out pkgbase manpages into separate packages by 42 default. To disable this, set WITHOUT_MANSPLITPKG=yes in src.conf. 43 4420230911: 45 Move standard include files to the clibs-dev package and move clang 46 internal libraries and headers to clang and clang-dev. Upgrading systems 47 installed using pkgbase past this change involves extra steps to allow 48 for these file moves: 49 50 pkg upgrade -y FreeBSD-utilities 51 pkg upgrade -y FreeBSD-utilities-dev 52 pkg upgrade -y 53 5420230909: 55 Enable vnet sysctl variables to be loader tunable. SYSCTLs which 56 belongs to VNETs can be initialized during early boot or module 57 loading if they are marked with CTLFLAG_TUN and there are 58 corresponding kernel environment variables. 59 6020230901: 61 The WITH_INIT_ALL_PATTERN and WITH_INIT_ALL_ZERO build options have 62 been replaced by INIT_ALL=pattern and INIT_ALL=zero respectively. 63 6420230824: 65 FreeBSD 15.0-CURRENT. 66 6720230817: 68 Serial communication (in boot loaders, kernel, and userland) has 69 been changed to default to 115200 bps, in line with common industry 70 practice and typcial firmware serial console redirection 71 configuration. 72 73 Note that the early x86 BIOS bootloader (i.e., boot0sio) does not 74 support rates above 9600 bps and is not changed. boot0sio users may 75 set BOOT_COMCONSOLE_SPEED=9600 to use 9600 for all of the boot 76 components, or use the standard boot0 and have the boot2 stage start 77 with the serial port at 115200. 78 7920230807: 80 Following the general removal of MIPS support, the ath(4) AHB bus- 81 frontend has been removed, too, and building of the PCI support is 82 integrated with the ath(4) main module again. As a result, there's 83 no longer a need for if_ath_pci_load="YES" in /boot/loader.conf or 84 "device ath_pci" in the kernel configuration. 85 8620230803: 87 MAXCPU has been increased to 1024 in the amd64 GENERIC kernel config. 88 Out-of-tree kernel modules will need to be rebuilt. 89 9020230724: 91 CAM has been mechanically updated s/u_int(64|32|16|8)_t/uint\1_t/g 92 to move to the standard uintXX_t types from the old, traditional 93 BSD u_intXX_t types. This should be a NOP, but may cause problems 94 for out of tree changes. The SIMs were not updated since most of 95 the old u_intXX_t uses weren't due to CAM interfaces. 96 9720230629: 98 The heuristic for detecting old chromebooks with an EC bug that requires 99 atkbdc driver workarounds has changed. There should be no functional 100 change, but if your old chromebook's keyboard stops working, please 101 file a PR and assign it to imp. 102 10320230623: 104 OpenSSL has been updated to version 3.0, including changes throughout 105 the base system. It is important to rebuild third-party software 106 after upgrading. 107 10820230619: 109 To enable pf rdr rules for connections initiated from the host, pf 110 filter rules can be optionally enabled for packets delivered 111 locally. This can change the behavior of rules which match packets 112 delivered to lo0. To enable this feature: 113 114 sysctl net.pf.filter_local=1 115 service pf restart 116 117 When enabled, its best to ensure that packets delivered locally are not 118 filtered, e.g. by adding a 'skip on lo' rule. 119 12020230613: 121 Improvements to libtacplus(8) mean that tacplus.conf(5) now 122 follows POSIX shell syntax rules. This may cause TACACS+ 123 authentication to fail if the shared secret contains a single 124 quote, double quote, or backslash character which isn't 125 already properly quoted or escaped. 126 12720230612: 128 Belatedly switch the default nvme block device on x86 from nvd to nda. 129 nda created nvd compatibility links by default, so this should be a 130 nop. If this causes problems for your application, set hw.nvme.use_nvd=1 131 in your loader.conf or add `options NVME_USE_NVD=1` to your kernel 132 config. To disable the nvd compatibility aliases, add 133 kern.cam.nda.nvd_compat=0 to loader.conf. The default has been nda on 134 all non-x86 platforms for some time now. If you need to fall back, 135 please email imp@freebsd.org about why. 136 137 Encrypted swap partitions need to be changed from nvd to nda if you 138 migrate, or you need to use the above to switch back to nvd. 139 14020230422: 141 Remove portsnap(8). Users are encouraged to obtain the ports tree 142 using git instead. 143 14420230420: 145 Add jobs.mk to save typing. Enables -j${JOB_MAX} and logging 146 eg. 147 make buildworld-jobs 148 runs 149 make -j${JOB_MAX} buildworld > ../buildworld.log 2>&1 150 151 where JOB_MAX is derrived from ncpus in local.sys.mk if not set in env. 152 15320230316: 154 Video related devices for some arm devices have been renamed. 155 If you have a custom kernel config and want to use hdmi output on 156 IMX6 board you need to add "device dwc_hdmi" "device imx6_hdmi" and 157 "device imx6_ipu" to it. 158 If you have a custom kernel config and want to use hdmi output on 159 TI AM335X board you need to add "device tda19988" to it. 160 If you add "device hdmi" in it you need to remove it as it doesn't 161 exist anymore. 162 16320230221: 164 Introduce new kernel options KBD_DELAY1 and KBD_DELAY2. See atkbdc(4) 165 for details. 166 16720230206: 168 sshd now defaults to having X11Forwarding disabled, following upstream. 169 Administrators who wish to enable X11Forwarding should add 170 `X11Forwarding yes` to /etc/ssh/sshd_config. 171 17220230204: 173 Since commit 75d41cb6967 Huawei 3G/4G LTE Mobile Devices do not default 174 to ECM, but NCM mode and need u3g and ucom modules loaded. See cdce(4). 175 17620230130: 177 As of commit 7c40e2d5f685, the dependency on netlink(4) has been added 178 to the linux_common(4) module. Users relying on linux_common may need 179 to complile netlink(4) module if it is not present in their kernel. 180 18120230126: 182 The WITHOUT_CXX option has been removed. C++ components in the base 183 system are now built unconditionally. 184 18520230113: 186 LinuxKPI pci.h changes may require out-of-tree drivers to be recompiled. 187 Bump _FreeBSD_version to 1400078 to be able to detect this change. 188 18920221212: 190 llvm-objump is now always installed as objdump. Previously there was 191 no /usr/bin/objdump unless the WITH_LLVM_BINUTILS knob was used. 192 193 Some LLVM objdump options have a different output format compared to 194 GNU objdump; readelf is available for inspecting ELF files, and GNU 195 objdump is available from the devel/binutils port or package. 196 19720221205: 198 dma(8) has replaced sendmail(8) as the default mta. For people willing 199 to reenable sendmail(8): 200 201 $ cp /usr/share/examples/sendmail/mailer.conf /etc/mail/mailer.conf 202 203 and add sendmail_enable="YES" to rc.conf. 204 20520221204: 206 hw.bus.disable_failed_devices has changed from 'false' to 'true' by 207 default. Now if newbus succeeds in probing a device, but fails to attach 208 the device, we'll disable the device. In the past, we'd keep retrying 209 the device on each new driver loaded. To get that behavior now, one 210 needs to use devctl to re-enable the device, and reprobe it (or set 211 the sysctl/tunable hw.bus.disable_failed_devices=false). 212 213 NOTE: This was reverted 20221205 due to unexpected compatibility issues 214 21520221122: 216 pf no longer accepts 'scrub fragment crop' or 'scrub fragment drop-ovl'. 217 These configurations are no longer automatically reinterpreted as 218 'scrub fragment reassemble'. 219 22020221121: 221 The WITHOUT_CLANG_IS_CC option has been removed. When Clang is enabled 222 it is always installed as /usr/bin/cc (and c++, cpp). 223 22420221026: 225 Some programs have been moved into separate packages. It is recommended 226 for pkgbase users to do: 227 228 pkg install FreeBSD-dhclient FreeBSD-geom FreeBSD-resolvconf \ 229 FreeBSD-devd FreeBSD-devmatch 230 231 after upgrading to restore all the component that were previously 232 installed. 233 23420221002: 235 OPIE has been removed from the base system. If needed, it can 236 be installed from ports (security/opie) or packages (opie). 237 Otherwise, make sure that your PAM policies do not reference 238 pam_opie or pam_opieaccess. 239 24020220610: 241 LinuxKPI pm.h changes require an update to the latest drm-kmod version 242 before re-compiling to avoid errors. 243 24420211230: 245 The macros provided for the manipulation of CPU sets (e.g. CPU_AND) 246 have been modified to take 2 source arguments instead of only 1. 247 Externally maintained sources that use these macros will have to 248 be adapted. The FreeBSD version has been bumped to 1400046 to 249 reflect this change. 250 25120211214: 252 A number of the kernel include files are able to be included by 253 themselves. A test has been added to buildworld to enforce this. 254 25520211209: 256 Remove mips as a recognized target. This starts the decommissioning of 257 mips support in FreeBSD. mips related items will be removed wholesale in 258 the coming days and weeks. 259 260 This broke the NO_CLEAN build for some people. Either do a clean build 261 or touch 262 lib/clang/include/llvm/Config/Targets.def 263 lib/clang/include/llvm/Config/AsmParsers.def 264 lib/clang/include/llvm/Config/Disassemblers.def 265 lib/clang/include/llvm/Config/AsmPrinters.def 266 before the build to force everything to rebuild that needs to. 267 26820211202: 269 Unbound support for RFC8375: The special-use domain 'home.arpa' is 270 by default blocked. To unblock it use a local-zone nodefault 271 statement in unbound.conf: 272 local-zone: "home.arpa." nodefault 273 274 Or use another type of local-zone to override with your choice. 275 276 The reason for this is discussed in Section 6.1 of RFC8375: 277 Because 'home.arpa.' is not globally scoped and cannot be secured 278 using DNSSEC based on the root domain's trust anchor, there is no way 279 to tell, using a standard DNS query, in which homenet scope an answer 280 belongs. Consequently, users may experience surprising results with 281 such names when roaming to different homenets. 282 28320211110: 284 Commit b8d60729deef changed the TCP congestion control framework so 285 that any of the included congestion control modules could be 286 the single module built into the kernel. Previously newreno 287 was automatically built in through direct reference. As of 288 this commit you are required to declare at least one congestion 289 control module (e.g. 'options CC_NEWRENO') and to also declare a 290 default using the CC_DEFAULT option (e.g. options CC_DEFAULT="newreno\"). 291 The GENERIC configuration includes CC_NEWRENO and defines newreno 292 as the default. If no congestion control option is built into the 293 kernel and you are including networking, the kernel compile will 294 fail. Also if no default is declared the kernel compile will fail. 295 29620211118: 297 Mips has been removed from universe builds. It will be removed from the 298 tree shortly. 299 30020211106: 301 Commit f0c9847a6c47 changed the arguments for VOP_ALLOCATE. 302 The NFS modules must be rebuilt from sources and any out 303 of tree file systems that implement their own VOP_ALLOCATE 304 may need to be modified. 305 30620211022: 307 The synchronous PPP kernel driver sppp(4) has been removed. 308 The cp(4) and ce(4) drivers are now always compiled with netgraph(4) 309 support, formerly enabled by NETGRAPH_CRONYX option. 310 31120211020: 312 sh(1) is now the default shell for the root user. To force root to use 313 the csh shell, please run the following command as root: 314 315 # chsh -s csh 316 31720211004: 318 Ncurses distribution has been split between libtinfow and libncurses 319 with libncurses.so becoming a linker (ld) script to seamlessly link 320 to libtinfow as needed. Bump _FreeBSD_version to 1400035 to reflect 321 this change. 322 32320210923: 324 As of commit 8160a0f62be6, the dummynet module no longer depends on the 325 ipfw module. Dummynet can now be used by pf as well as ipfw. As such 326 users who relied on this dependency may need to include ipfw in the 327 list of modules to load on their systems. 328 32920210922: 330 As of commit 903873ce1560, the mixer(8) utility has got a slightly 331 new syntax. Please refer to the mixer(8) manual page for more 332 information. The old mixer utility can be installed from ports: 333 audio/freebsd-13-mixer 334 33520210911: 336 As of commit 55089ef4f8bb, the global variable nfs_maxcopyrange has 337 been deleted from the nfscommon.ko. As such, nfsd.ko must be built 338 from up to date sources to avoid an undefined reference when 339 being loaded. 340 34120210817: 342 As of commit 62ca9fc1ad56 OpenSSL no longer enables kernel TLS 343 by default. Users can enable kernel TLS via the "KTLS" SSL 344 option. This can be enabled globally by using a custom 345 OpenSSL config file via OPENSSL_CONF or via an 346 application-specific configuration option for applications 347 which permit setting SSL options via SSL_CONF_cmd(3). 348 34920210811: 350 Commit 3ad1e1c1ce20 changed the internal KAPI between the NFS 351 modules. Therefore, all need to be rebuilt from sources. 352 35320210730: 354 Commit b69019c14cd8 removes pf's DIOCGETSTATESNV ioctl. 355 As of be70c7a50d32 it is no longer used by userspace, but it does mean 356 users may not be able to enumerate pf states if they update the kernel 357 past b69019c14cd8 without first updating userspace past be70c7a50d32. 358 35920210729: 360 As of commit 01ad0c007964 if_bridge member interfaces can no longer 361 change their MTU. Changing the MTU of the bridge itself will change the 362 MTU on all member interfaces instead. 363 36420210716: 365 Commit ee29e6f31111 changed the internal KAPI between the nfscommon 366 and nfsd modules. Therefore, both need to be rebuilt from sources. 367 Bump __FreeBSD_version to 1400026 for this KAPI change. 368 36920210715: 370 The 20210707 awk update brought in a change in behavior. This has 371 been corrected as of d4d252c49976. Between these dates, if you 372 installed a new awk binary, you may not be able to build a new 373 kernel because the change in behavior affected the genoffset 374 script used to build the kernel. If you did update, the fix is 375 to update your sources past the above hash and do 376 % cd usr.bin/awk 377 % make clean all 378 % sudo -E make install 379 to enable building kernels again. 380 38120210708: 382 Commit 1e0a518d6548 changed the internal KAPI between the NFS 383 modules. They all need to be rebuilt from sources. I did not 384 bump __FreeBSD_version, since it was bumped recently. 385 38620210707: 387 awk has been updated to the latest one-true-awk version 20210215. 388 This contains a number of minor bug fixes. 389 39020210624: 391 The NFSv4 client now uses the highest minor version of NFSv4 392 supported by the NFSv4 server by default instead of minor version 0, 393 for NFSv4 mounts. 394 The "minorversion" mount option may be used to override this default. 395 39620210618: 397 Bump __FreeBSD_version to 1400024 for LinuxKPI changes. 398 Most notably netdev.h can change now as the (last) dependencies 399 (mlx4/ofed) are now using struct ifnet directly, but also for PCI 400 additions and others. 401 40220210618: 403 The directory "blacklisted" under /usr/share/certs/ has been 404 renamed to "untrusted". 405 40620210611: 407 svnlite has been removed from base. Should you need svn for any reason 408 please install the svn package or port. 409 41020210611: 411 Commit e1a907a25cfa changed the internal KAPI between the krpc 412 and nfsserver. As such, both modules must be rebuilt from 413 sources. Bump __FreeBSD_version to 1400022. 414 41520210610: 416 The an(4) driver has been removed from FreeBSD. 417 41820210608: 419 The vendor/openzfs branch was renamed to vendor/openzfs/legacy to 420 start tracking OpenZFS upstream more closely. Please see 421https://lists.freebsd.org/archives/freebsd-current/2021-June/000153.html 422 for details on how to correct any errors that might result. The 423 short version is that you need to remove the old branch locally: 424 git update-ref -d refs/remotes/freebsd/vendor/openzfs 425 (assuming your upstream origin is named 'freebsd'). 426 42720210525: 428 Commits 17accc08ae15 and de102f870501 add new files to LinuxKPI 429 which break drm-kmod. In addition various other additions where 430 committed. Bump __FreeBSD_version to 1400015 to be able to 431 detect this. 432 43320210513: 434 Commit ca179c4d74f2 changed the package in which the OpenSSL 435 libraries and utilities are packaged. 436 It is recommended for pkgbase user to do: 437 pkg install -f FreeBSD-openssl 438 before pkg upgrade otherwise some dependencies might not be met 439 and pkg will stop working as libssl will not be present anymore 440 on the system. 441 44220210426: 443 Commit 875977314881 changed the internal KAPI between 444 the nfsd and nfscommon modules. As such these modules 445 need to be rebuilt from sources. 446 Without this patch in your NFSv4.1/4.2 server, enabling 447 delegations by setting vfs.nfsd.issue_delegations non-zero 448 is not recommended. 449 45020210411: 451 Commit 7763814fc9c2 changed the internal KAPI between 452 the krpc and NFS. As such, the krpc, nfscommon and 453 nfscl modules must all be rebuilt from sources. 454 Without this patch, NFSv4.1/4.2 mounts should not 455 be done with the nfscbd(8) daemon running, to avoid 456 needing a working back channel for server->client RPCs. 457 45820210330: 459 Commit 01ae8969a9ee fixed the NFSv4.1/4.2 server so that it 460 handles binding of the back channel as required by RFC5661. 461 Until this patch is in your server, avoid use of the "nconnects" 462 mount option for Linux NFSv4.1/4.2 mounts. 463 46420210225: 465 For 64-bit architectures the base system is now built with Position 466 Independent Executable (PIE) support enabled by default. It may be 467 disabled using the WITHOUT_PIE knob. A clean build is required. 468 46920210128: 470 Various LinuxKPI functionality was added which conflicts with DRM. 471 Please update your drm-kmod port to after the __FreeBSD_version 1400003 472 update. 473 47420210108: 475 PC Card attachments for all devices have been removed. In the case of 476 wi and cmx, the entire drivers were removed because they were only 477 PC Card devices. FreeBSD_version 1300134 should be used for this 478 since it was bumped so recently. 479 48020210107: 481 Transport-independent parts of HID support have been split off the USB 482 code in to separate subsystem. Kernel configs which include one of 483 ums, ukbd, uhid, atp, wsp, wmt, uaudio, ugold or ucycom drivers should 484 be updated with adding of "device hid" line. 485 48620210105: 487 ncurses installation has been modified to only keep the widechar 488 enabled version. Incremental build is broken for that change, so it 489 requires a clean build. 490 49120201223: 492 The FreeBSD project has migrated from Subversion to Git. Temporary 493 instructions can be found at 494 https://github.com/bsdimp/freebsd-git-docs/blob/main/src-cvt.md 495 and other documents in that repo. 496 49720201216: 498 The services database has been updated to cover more of the basic 499 services expected in a modern system. The database is big enough 500 that it will cause issues in mergemaster in Releases previous to 501 12.2 and 11.3, or in very old current systems from before r358154. 502 50320201215: 504 Obsolete in-tree GDB 6.1.1 has been removed. GDB (including kgdb) 505 may be installed from ports or packages. 506 50720201124: 508 ping6 has been merged into ping. It can now be called as "ping -6". 509 See ping(8) for details. 510 51120201108: 512 Default value of net.add_addr_allfibs has been changed to 0. 513 If you have multi-fib configuration and rely on existence of all 514 interface routes in every fib, you need to set the above sysctl to 1. 515 51620201030: 517 The internal pre-processor in the calendar(1) program has been 518 extended to support more C pre-processor commands (e.g. #ifdef, #else, 519 and #undef) and to detect unbalanced conditional statements. 520 Error messages have been extended to include the filename and line 521 number if processing stops to help fixing malformed data files. 522 52320201026: 524 All the data files for the calendar(1) program, except calendar.freebsd, 525 have been moved to the deskutils/calendar-data port, much like the 526 jewish calendar entries were moved to deskutils/hebcal years ago. After 527 make delete-old-files, you need to install it to retain full 528 functionality. calendar(1) will issue a reminder for files it can't 529 find. 530 53120200923: 532 LINT files are no longer generated. We now include the relevant NOTES 533 files. Note: This may cause conflicts with updating in some cases. 534 find sys -name LINT\* -delete 535 is suggested across this commit to remove the generated LINT files. 536 537 If you have tried to update with generated files there, the svn 538 command you want to un-auger the tree is 539 cd sys/amd64/conf 540 svn revert -R . 541 and then do the above find from the top level. Substitute 'amd64' 542 above with where the error message indicates a conflict. 543 54420200824: 545 OpenZFS support has been integrated. Do not upgrade root pools until 546 the loader is updated to support zstd. Furthermore, we caution against 547 'zpool upgrade' for the next few weeks. The change should be transparent 548 unless you want to use new features. 549 550 Not all "NO_CLEAN" build scenarios work across these changes. Many 551 scenarios have been tested and fixed, but rebuilding kernels without 552 rebuilding world may fail. 553 554 The ZFS cache file has moved from /boot to /etc to match the OpenZFS 555 upstream default. A fallback to /boot has been added for mountroot. 556 557 Pool auto import behavior at boot has been moved from the kernel module 558 to an explicit "zpool import -a" in one of the rc scripts enabled by 559 zfs_enable=YES. This means your non-root zpools won't auto import until 560 you upgrade your /etc/rc.d files. 561 56220200824: 563 The resume code now notifies devd with the 'kernel' system 564 rather than the old 'kern' subsystem to be consistent with 565 other use. The old notification will be created as well, but 566 will be removed prior to FreeBSD 14.0. 567 56820200821: 569 r362275 changed the internal API between the kernel RPC and the 570 NFS modules. As such, all the modules must be recompiled from 571 sources. 572 57320200817: 574 r364330 modified the internal API used between the NFS modules. 575 As such, all the NFS modules must be re-compiled from sources. 576 57720200816: 578 Clang, llvm, lld, lldb, compiler-rt, libc++, libunwind and openmp have 579 been upgraded to 11.0.0. Please see the 20141231 entry below for 580 information about prerequisites and upgrading, if you are not already 581 using clang 3.5.0 or higher. 582 58320200810: 584 r364092 modified the internal ABI used between the kernel NFS 585 modules. As such, all of these modules need to be rebuilt 586 from sources, so a version bump was done. 587 58820200807: 589 Makefile.inc has been updated to work around the issue documented in 590 20200729. It was a case where the optimization of using symbolic links 591 to point to binaries created a situation where we'd run new binaries 592 with old libraries starting midway through the installworld process. 593 59420200729: 595 r363679 has redefined some undefined behavior in regcomp(3); notably, 596 extraneous escapes of most ordinary characters will no longer be 597 accepted. An exp-run has identified all of the problems with this in 598 ports, but other non-ports software may need extra escapes removed to 599 continue to function. 600 601 Because of this change, installworld may encounter the following error 602 from rtld: Undefined symbol "regcomp@FBSD_1.6" -- It is imperative that 603 you do not halt installworld. Instead, let it run to completion (whether 604 successful or not) and run installworld once more. 605 60620200627: 607 A new implementation of bc and dc has been imported in r362681. This 608 implementation corrects non-conformant behavior of the previous bc 609 and adds GNU bc compatible options. It offers a number of extensions, 610 is much faster on large values, and has support for message catalogs 611 (a number of languages are already supported, contributions of further 612 languages welcome). The option WITHOUT_GH_BC can be used to build the 613 world with the previous versions of bc and dc. 614 61520200625: 616 r362639 changed the internal API used between the NFS kernel modules. 617 As such, they all need to be rebuilt from sources. 618 61920200613: 620 r362158 changed the arguments for VFS_CHECKEXP(). As such, any 621 out of tree file systems need to be modified and rebuilt. 622 Also, any file systems that are modules must be rebuilt. 623 62420200604: 625 read(2) of a directory fd is now rejected by default. root may 626 re-enable it for system root only on non-ZFS filesystems with the 627 security.bsd.allow_read_dir sysctl(8) MIB if 628 security.bsd.suser_enabled=1. 629 630 It may be advised to setup aliases for grep to default to `-d skip` if 631 commonly non-recursively grepping a list that includes directories and 632 the potential for the resulting stderr output is not tolerable. Example 633 aliases are now installed, commented out, in /root/.cshrc and 634 /root/.shrc. 635 63620200523: 637 Clang, llvm, lld, lldb, compiler-rt, libc++, libunwind and openmp have 638 been upgraded to 10.0.1. Please see the 20141231 entry below for 639 information about prerequisites and upgrading, if you are not already 640 using clang 3.5.0 or higher. 641 64220200512: 643 Support for obsolete compilers has been removed from the build system. 644 Clang 6 and GCC 6.4 are the minimum supported versions. 645 64620200424: 647 closefrom(2) has been moved under COMPAT12, and replaced in libc with a 648 stub that calls close_range(2). If using a custom kernel configuration, 649 you may want to ensure that the COMPAT_FREEBSD12 option is included, as 650 a slightly older -CURRENT userland and older FreeBSD userlands may not 651 be functional without closefrom(2). 652 65320200414: 654 Upstream DTS from Linux 5.6 was merged and they now have the SID 655 and THS (Secure ID controller and THermal Sensor) node present. 656 The DTB overlays have now been removed from the tree for the H3/H5 and 657 A64 SoCs and the aw_sid and aw_thermal driver have been updated to 658 deal with upstream DTS. If you are using those overlays you need to 659 remove them from loader.conf and update the DTBs on the FAT partition. 660 66120200310: 662 Clang, llvm, lld, lldb, compiler-rt, libc++, libunwind and openmp have 663 been upgraded to 10.0.0. Please see the 20141231 entry below for 664 information about prerequisites and upgrading, if you are not already 665 using clang 3.5.0 or higher. 666 66720200309: 668 The amd(8) automount daemon has been removed from the source tree. 669 As of FreeBSD 10.1 autofs(5) is the preferred tool for automounting. 670 amd is still available in the sysutils/am-utils port. 671 67220200301: 673 Removed brooktree driver (bktr.4) from the tree. 674 67520200229: 676 The WITH_GPL_DTC option has been removed. The BSD-licenced device tree 677 compiler in usr.bin/dtc is used on all architectures which use dtc, and 678 the GPL dtc is available (if needed) from the sysutils/dtc port. 679 68020200229: 681 The WITHOUT_LLVM_LIBUNWIND option has been removed. LLVM's libunwind 682 is used by all supported CPU architectures. 683 68420200229: 685 GCC 4.2.1 has been removed from the tree. The WITH_GCC, 686 WITH_GCC_BOOTSTRAP, and WITH_GNUCXX options are no longer available. 687 Users who wish to build FreeBSD with GCC must use the external toolchain 688 ports or packages. 689 69020200220: 691 ncurses has been updated to a newer version (6.2-20200215). Given the ABI 692 has changed, users will have to rebuild all the ports that are linked to 693 ncurses. 694 69520200217: 696 The size of struct vnet and the magic cookie have changed. 697 Users need to recompile libkvm and all modules using VIMAGE 698 together with their new kernel. 699 70020200212: 701 Defining the long deprecated NO_CTF, NO_DEBUG_FILES, NO_INSTALLLIB, 702 NO_MAN, NO_PROFILE, and NO_WARNS variables is now an error. Update 703 your Makefiles and scripts to define MK_<var>=no instead as required. 704 705 One exception to this is that program or library Makefiles should 706 define MAN to empty rather than setting MK_MAN=no. 707 70820200108: 709 Clang/LLVM is now the default compiler and LLD the default 710 linker for riscv64. 711 71220200107: 713 make universe no longer uses GCC 4.2.1 on any architectures. 714 Architectures not supported by in-tree Clang/LLVM require an 715 external toolchain package. 716 71720200104: 718 GCC 4.2.1 is now not built by default, as part of the GCC 4.2.1 719 retirement plan. Specifically, the GCC, GCC_BOOTSTRAP, and GNUCXX 720 options default to off for all supported CPU architectures. As a 721 short-term transition aid they may be enabled via WITH_* options. 722 GCC 4.2.1 is expected to be removed from the tree on 2020-03-31. 723 72420200102: 725 Support for armv5 has been disconnected and is being removed. The 726 machine combination MACHINE=arm MACHINE_ARCH=arm is no longer valid. 727 You must now use a MACHINE_ARCH of armv6 or armv7. The default 728 MACHINE_ARCH for MACHINE=arm is now armv7. 729 73020191226: 731 Clang/LLVM is now the default compiler for all powerpc architectures. 732 LLD is now the default linker for powerpc64. The change for powerpc64 733 also includes a change to the ELFv2 ABI, incompatible with the existing 734 ABI. 735 73620191226: 737 Kernel-loadable random(4) modules are no longer unloadable. 738 73920191222: 740 Clang, llvm, lld, lldb, compiler-rt, libc++, libunwind and openmp have 741 been upgraded to 9.0.1. Please see the 20141231 entry below for 742 information about prerequisites and upgrading, if you are not already 743 using clang 3.5.0 or higher. 744 74520191212: 746 r355677 has modified the internal interface used between the 747 NFS modules in the kernel. As such, they must all be upgraded 748 simultaneously. I will do a version bump for this. 749 75020191205: 751 The root certificates of the Mozilla CA Certificate Store have been 752 imported into the base system and can be managed with the certctl(8) 753 utility. If you have installed the security/ca_root_nss port or package 754 with the ETCSYMLINK option (the default), be advised that there may be 755 differences between those included in the port and those included in 756 base due to differences in nss branch used as well as general update 757 frequency. Note also that certctl(8) cannot manage certs in the 758 format used by the security/ca_root_nss port. 759 76020191120: 761 The amd(8) automount daemon has been disabled by default, and will be 762 removed in the future. As of FreeBSD 10.1 the autofs(5) is available 763 for automounting. 764 76520191107: 766 The nctgpio and wbwd drivers have been moved to the superio bus. 767 If you have one of these drivers in a kernel configuration, then 768 you should add device superio to it. If you use one of these drivers 769 as a module and you compile a custom set of modules, then you should 770 add superio to the set. 771 77220191021: 773 KPIs for network drivers to access interface addresses have changed. 774 Users need to recompile NIC driver modules together with kernel. 775 77620191021: 777 The net.link.tap.user_open sysctl no longer prevents user opening of 778 already created /dev/tapNN devices. Access is still controlled by 779 node permissions, just like tun devices. The net.link.tap.user_open 780 sysctl is now used only to allow users to perform devfs cloning of 781 tap devices, and the subsequent open may not succeed if the user is not 782 in the appropriate group. This sysctl may be deprecated/removed 783 completely in the future. 784 78520191009: 786 mips, powerpc, and sparc64 are no longer built as part of 787 universe / tinderbox unless MAKE_OBSOLETE_GCC is defined. If 788 not defined, mips, powerpc, and sparc64 builds will look for 789 the xtoolchain binaries and if installed use them for universe 790 builds. As llvm 9.0 becomes vetted for these architectures, they 791 will be removed from the list. 792 79320191009: 794 Clang, llvm, lld, lldb, compiler-rt, libc++, libunwind and openmp have 795 been upgraded to 9.0.0. Please see the 20141231 entry below for 796 information about prerequisites and upgrading, if you are not already 797 using clang 3.5.0 or higher. 798 79920191003: 800 The hpt27xx, hptmv, hptnr, and hptrr drivers have been removed from 801 GENERIC. They are available as modules and can be loaded by adding 802 to /boot/loader.conf hpt27xx_load="YES", hptmv_load="YES", 803 hptnr_load="YES", or hptrr_load="YES", respectively. 804 80520190913: 806 ntpd no longer by default locks its pages in memory, allowing them 807 to be paged out by the kernel. Use rlimit memlock to restore 808 historic BSD behaviour. For example, add "rlimit memlock 32" 809 to ntp.conf to lock up to 32 MB of ntpd address space in memory. 810 81120190823: 812 Several of ping6's options have been renamed for better consistency 813 with ping. If you use any of -ARWXaghmrtwx, you must update your 814 scripts. See ping6(8) for details. 815 81620190727: 817 The vfs.fusefs.sync_unmount and vfs.fusefs.init_backgrounded sysctls 818 and the "-o sync_unmount" and "-o init_backgrounded" mount options have 819 been removed from mount_fusefs(8). You can safely remove them from 820 your scripts, because they had no effect. 821 822 The vfs.fusefs.fix_broken_io, vfs.fusefs.sync_resize, 823 vfs.fusefs.refresh_size, vfs.fusefs.mmap_enable, 824 vfs.fusefs.reclaim_revoked, and vfs.fusefs.data_cache_invalidate 825 sysctls have been removed. If you felt the need to set any of them to 826 a non-default value, please tell asomers@FreeBSD.org why. 827 82820190713: 829 Default permissions on the /var/account/acct file (and copies of it 830 rotated by periodic daily scripts) are changed from 0644 to 0640 831 because the file contains sensitive information that should not be 832 world-readable. If the /var/account directory must be created by 833 rc.d/accounting, the mode used is now 0750. Admins who use the 834 accounting feature are encouraged to change the mode of an existing 835 /var/account directory to 0750 or 0700. 836 83720190620: 838 Entropy collection and the /dev/random device are no longer optional 839 components. The "device random" option has been removed. 840 Implementations of distilling algorithms can still be made loadable 841 with "options RANDOM_LOADABLE" (e.g., random_fortuna.ko). 842 84320190612: 844 Clang, llvm, lld, lldb, compiler-rt, libc++, libunwind and openmp have 845 been upgraded to 8.0.1. Please see the 20141231 entry below for 846 information about prerequisites and upgrading, if you are not already 847 using clang 3.5.0 or higher. 848 84920190608: 850 A fix was applied to i386 kernel modules to avoid panics with 851 dpcpu or vnet. Users need to recompile i386 kernel modules 852 having pcpu or vnet sections or they will refuse to load. 853 85420190513: 855 User-wired pages now have their own counter, 856 vm.stats.vm.v_user_wire_count. The vm.max_wired sysctl was renamed 857 to vm.max_user_wired and changed from an unsigned int to an unsigned 858 long. bhyve VMs wired with the -S are now subject to the user 859 wiring limit; the vm.max_user_wired sysctl may need to be tuned to 860 avoid running into the limit. 861 86220190507: 863 The IPSEC option has been removed from GENERIC. Users requiring 864 ipsec(4) must now load the ipsec(4) kernel module. 865 86620190507: 867 The tap(4) driver has been folded into tun(4), and the module has been 868 renamed to tuntap. You should update any kld_list="if_tap" or 869 kld_list="if_tun" entries in /etc/rc.conf, if_tap_load="YES" or 870 if_tun_load="YES" entries in /boot/loader.conf to load the if_tuntap 871 module instead, and "device tap" or "device tun" entries in kernel 872 config files to select the tuntap device instead. 873 87420190418: 875 The following knobs have been added related to tradeoffs between 876 safe use of the random device and availability in the absence of 877 entropy: 878 879 kern.random.initial_seeding.bypass_before_seeding: tunable; set 880 non-zero to bypass the random device prior to seeding, or zero to 881 block random requests until the random device is initially seeded. 882 For now, set to 1 (unsafe) by default to restore pre-r346250 boot 883 availability properties. 884 885 kern.random.initial_seeding.read_random_bypassed_before_seeding: 886 read-only diagnostic sysctl that is set when bypass is enabled and 887 read_random(9) is bypassed, to enable programmatic handling of this 888 initial condition, if desired. 889 890 kern.random.initial_seeding.arc4random_bypassed_before_seeding: 891 Similar to the above, but for arc4random(9) initial seeding. 892 893 kern.random.initial_seeding.disable_bypass_warnings: tunable; set 894 non-zero to disable warnings in dmesg when the same conditions are 895 met as for the diagnostic sysctls above. Defaults to zero, i.e., 896 produce warnings in dmesg when the conditions are met. 897 89820190416: 899 The loadable random module KPI has changed; the random_infra_init() 900 routine now requires a 3rd function pointer for a bool (*)(void) 901 method that returns true if the random device is seeded (and 902 therefore unblocked). 903 90420190404: 905 r345895 reverts r320698. This implies that an nfsuserd(8) daemon 906 built from head sources between r320757 (July 6, 2017) and 907 r338192 (Aug. 22, 2018) will not work unless the "-use-udpsock" 908 is added to the command line. 909 nfsuserd daemons built from head sources that are post-r338192 are 910 not affected and should continue to work. 911 91220190320: 913 The fuse(4) module has been renamed to fusefs(4) for consistency with 914 other filesystems. You should update any kld_load="fuse" entries in 915 /etc/rc.conf, fuse_load="YES" entries in /boot/loader.conf, and 916 "options FUSE" entries in kernel config files. 917 91820190304: 919 Clang, llvm, lld, lldb, compiler-rt and libc++ have been upgraded to 920 8.0.0. Please see the 20141231 entry below for information about 921 prerequisites and upgrading, if you are not already using clang 3.5.0 922 or higher. 923 92420190226: 925 geom_uzip(4) depends on the new module xz. If geom_uzip is statically 926 compiled into your custom kernel, add 'device xz' statement to the 927 kernel config. 928 92920190219: 930 drm and drm2 have been removed from the tree. Please see 931 https://wiki.freebsd.org/Graphics for the latest information on 932 migrating to the drm ports. 933 93420190131: 935 Iflib is no longer unconditionally compiled into the kernel. Drivers 936 using iflib and statically compiled into the kernel, now require 937 the 'device iflib' config option. For the same drivers loaded as 938 modules on kernels not having 'device iflib', the iflib.ko module 939 is loaded automatically. 940 94120190125: 942 The IEEE80211_AMPDU_AGE and AH_SUPPORT_AR5416 kernel configuration 943 options no longer exist since r343219 and r343427 respectively; 944 nothing uses them, so they should be just removed from custom 945 kernel config files. 946 94720181230: 948 r342635 changes the way efibootmgr(8) works by requiring users to add 949 the -b (bootnum) parameter for commands where the bootnum was previously 950 specified with each option. For example 'efibootmgr -B 0001' is now 951 'efibootmgr -B -b 0001'. 952 95320181220: 954 r342286 modifies the NFSv4 server so that it obeys vfs.nfsd.nfs_privport 955 in the same as it is applied to NFSv2 and 3. This implies that NFSv4 956 servers that have vfs.nfsd.nfs_privport set will only allow mounts 957 from clients using a reserved port. Since both the FreeBSD and Linux 958 NFSv4 clients use reserved ports by default, this should not affect 959 most NFSv4 mounts. 960 96120181219: 962 The XLP config has been removed. We can't support 64-bit atomics in this 963 kernel because it is running in 32-bit mode. XLP users must transition 964 to running a 64-bit kernel (XLP64 or XLPN32). 965 966 The mips GXEMUL support has been removed from FreeBSD. MALTA* + qemu is 967 the preferred emulator today and we don't need two different ones. 968 969 The old sibyte / swarm / Broadcom BCM1250 support has been 970 removed from the mips port. 971 97220181211: 973 Clang, llvm, lld, lldb, compiler-rt and libc++ have been upgraded to 974 7.0.1. Please see the 20141231 entry below for information about 975 prerequisites and upgrading, if you are not already using clang 3.5.0 976 or higher. 977 97820181211: 979 Remove the timed and netdate programs from the base tree. Setting 980 the time with these daemons has been obsolete for over a decade. 981 98220181126: 983 On amd64, arm64 and armv7 (architectures that install LLVM's ld.lld 984 linker as /usr/bin/ld) GNU ld is no longer installed as ld.bfd, as 985 it produces broken binaries when ifuncs are in use. Users needing 986 GNU ld should install the binutils port or package. 987 98820181123: 989 The BSD crtbegin and crtend code has been enabled by default. It has 990 had extensive testing on amd64, arm64, and i386. It can be disabled 991 by building a world with -DWITHOUT_BSD_CRTBEGIN. 992 99320181115: 994 The set of CTM commands (ctm, ctm_smail, ctm_rmail, ctm_dequeue) 995 has been converted to a port (misc/ctm) and will be removed from 996 FreeBSD-13. It is available as a package (ctm) for all supported 997 FreeBSD versions. 998 99920181110: 1000 The default newsyslog.conf(5) file has been changed to only include 1001 files in /etc/newsyslog.conf.d/ and /usr/local/etc/newsyslog.conf.d/ if 1002 the filenames end in '.conf' and do not begin with a '.'. 1003 1004 You should check the configuration files in these two directories match 1005 this naming convention. You can verify which configuration files are 1006 being included using the command: 1007 $ newsyslog -Nrv 1008 100920181015: 1010 Ports for the DRM modules have been simplified. Now, amd64 users should 1011 just install the drm-kmod port. All others should install 1012 drm-legacy-kmod. 1013 1014 Graphics hardware that's newer than about 2010 usually works with 1015 drm-kmod. For hardware older than 2013, however, some users will need 1016 to use drm-legacy-kmod if drm-kmod doesn't work for them. Hardware older 1017 than 2008 usually only works in drm-legacy-kmod. The graphics team can 1018 only commit to hardware made since 2013 due to the complexity of the 1019 market and difficulty to test all the older cards effectively. If you 1020 have hardware supported by drm-kmod, you are strongly encouraged to use 1021 that as you will get better support. 1022 1023 Other than KPI chasing, drm-legacy-kmod will not be updated. As outlined 1024 elsewhere, the drm and drm2 modules will be eliminated from the src base 1025 soon (with a limited exception for arm). Please update to the package 1026 asap and report any issues to x11@freebsd.org. 1027 1028 Generally, anybody using the drm*-kmod packages should add 1029 WITHOUT_DRM_MODULE=t and WITHOUT_DRM2_MODULE=t to avoid nasty 1030 cross-threading surprises, especially with automatic driver 1031 loading from X11 startup. These will become the defaults in 13-current 1032 shortly. 1033 103420181012: 1035 The ixlv(4) driver has been renamed to iavf(4). As a consequence, 1036 custom kernel and module loading configuration files must be updated 1037 accordingly. Moreover, interfaces previous presented as ixlvN to the 1038 system are now exposed as iavfN and network configuration files must 1039 be adjusted as necessary. 1040 104120181009: 1042 OpenSSL has been updated to version 1.1.1. This update included 1043 additional various API changes throughout the base system. It is 1044 important to rebuild third-party software after upgrading. The value 1045 of __FreeBSD_version has been bumped accordingly. 1046 104720181006: 1048 The legacy DRM modules and drivers have now been added to the loader's 1049 module blacklist, in favor of loading them with kld_list in rc.conf(5). 1050 The module blacklist may be overridden with the loader.conf(5) 1051 'module_blacklist' variable, but loading them via rc.conf(5) is strongly 1052 encouraged. 1053 105420181002: 1055 The cam(4) based nda(4) driver will be used over nvd(4) by default on 1056 powerpc64. You may set 'options NVME_USE_NVD=1' in your kernel conf or 1057 loader tunable 'hw.nvme.use_nvd=1' if you wish to use the existing 1058 driver. Make sure to edit /boot/etc/kboot.conf and fstab to use the 1059 nda device name. 1060 106120180913: 1062 Reproducible build mode is now on by default, in preparation for 1063 FreeBSD 12.0. This eliminates build metadata such as the user, 1064 host, and time from the kernel (and uname), unless the working tree 1065 corresponds to a modified checkout from a version control system. 1066 The previous behavior can be obtained by setting the /etc/src.conf 1067 knob WITHOUT_REPRODUCIBLE_BUILD. 1068 106920180826: 1070 The Yarrow CSPRNG has been removed from the kernel as it has not been 1071 supported by its designers since at least 2003. Fortuna has been the 1072 default since FreeBSD-11. 1073 107420180822: 1075 devctl freeze/thaw have gone into the tree, the rc scripts have been 1076 updated to use them and devmatch has been changed. You should update 1077 kernel, userland and rc scripts all at the same time. 1078 107920180818: 1080 The default interpreter has been switched from 4th to Lua. 1081 LOADER_DEFAULT_INTERP, documented in build(7), will override the default 1082 interpreter. If you have custom FORTH code you will need to set 1083 LOADER_DEFAULT_INTERP=4th (valid values are 4th, lua or simp) in 1084 src.conf for the build. This will create default hard links between 1085 loader and loader_4th instead of loader and loader_lua, the new default. 1086 If you are using UEFI it will create the proper hard link to loader.efi. 1087 1088 bhyve uses userboot.so. It remains 4th-only until some issues are solved 1089 regarding coexisting with multiple versions of FreeBSD are resolved. 1090 109120180815: 1092 ls(1) now respects the COLORTERM environment variable used in other 1093 systems and software to indicate that a colored terminal is both 1094 supported and desired. If ls(1) is suddenly emitting colors, they may 1095 be disabled again by either removing the unwanted COLORTERM from your 1096 environment, or using `ls --color=never`. The ls(1) specific CLICOLOR 1097 may not be observed in a future release. 1098 109920180808: 1100 The default pager for most commands has been changed to "less". To 1101 restore the old behavior, set PAGER="more" and MANPAGER="more -s" in 1102 your environment. 1103 110420180731: 1105 The jedec_ts(4) driver has been removed. A superset of its functionality 1106 is available in the jedec_dimm(4) driver, and the manpage for that 1107 driver includes migration instructions. If you have "device jedec_ts" 1108 in your kernel configuration file, it must be removed. 1109 111020180730: 1111 amd64/GENERIC now has EFI runtime services, EFIRT, enabled by default. 1112 This should have no effect if the kernel is booted via BIOS/legacy boot. 1113 EFIRT may be disabled via a loader tunable, efi.rt.disabled, if a system 1114 has a buggy firmware that prevents a successful boot due to use of 1115 runtime services. 1116 111720180727: 1118 Atmel AT91RM9200 and AT91SAM9, Cavium CNS 11xx and XScale 1119 support has been removed from the tree. These ports were 1120 obsolete and/or known to be broken for many years. 1121 112220180723: 1123 loader.efi has been augmented to participate more fully in the 1124 UEFI boot manager protocol. loader.efi will now look at the 1125 BootXXXX environment variable to determine if a specific kernel 1126 or root partition was specified. XXXX is derived from BootCurrent. 1127 efibootmgr(8) manages these standard UEFI variables. 1128 112920180720: 1130 zfsloader's functionality has now been folded into loader. 1131 zfsloader is no longer necessary once you've updated your 1132 boot blocks. For a transition period, we will install a 1133 hardlink for zfsloader to loader to allow a smooth transition 1134 until the boot blocks can be updated (hard link because old 1135 zfs boot blocks don't understand symlinks). 1136 113720180719: 1138 ARM64 now have efifb support, if you want to have serial console 1139 on your arm64 board when an screen is connected and the bootloader 1140 setup a frame buffer for us to use, just add : 1141 boot_serial=YES 1142 boot_multicons=YES 1143 in /boot/loader.conf 1144 For Raspberry Pi 3 (RPI) users, this is needed even if you don't have 1145 an screen connected as the firmware will setup a frame buffer are that 1146 u-boot will expose as an EFI frame buffer. 1147 114820180719: 1149 New uid:gid added, ntpd:ntpd (123:123). Be sure to run mergemaster 1150 or take steps to update /etc/passwd before doing installworld on 1151 existing systems. Do not skip the "mergemaster -Fp" step before 1152 installworld, as described in the update procedures near the bottom 1153 of this document. Also, rc.d/ntpd now starts ntpd(8) as user ntpd 1154 if the new mac_ntpd(4) policy is available, unless ntpd_flags or 1155 the ntp config file contain options that change file/dir locations. 1156 When such options (e.g., "statsdir" or "crypto") are used, ntpd can 1157 still be run as non-root by setting ntpd_user=ntpd in rc.conf, after 1158 taking steps to ensure that all required files/dirs are accessible 1159 by the ntpd user. 1160 116120180717: 1162 Big endian arm support has been removed. 1163 116420180711: 1165 The static environment setup in kernel configs is no longer mutually 1166 exclusive with the loader(8) environment by default. In order to 1167 restore the previous default behavior of disabling the loader(8) 1168 environment if a static environment is present, you must specify 1169 loader_env.disabled=1 in the static environment. 1170 117120180705: 1172 The ABI of syscalls used by management tools like sockstat and 1173 netstat has been broken to allow 32-bit binaries to work on 1174 64-bit kernels without modification. These programs will need 1175 to match the kernel in order to function. External programs may 1176 require minor modifications to accommodate a change of type in 1177 structures from pointers to 64-bit virtual addresses. 1178 117920180702: 1180 On i386 and amd64 atomics are now inlined. Out of tree modules using 1181 atomics will need to be rebuilt. 1182 118320180701: 1184 The '%I' format in the kern.corefile sysctl limits the number of 1185 core files that a process can generate to the number stored in the 1186 debug.ncores sysctl. The '%I' format is replaced by the single digit 1187 index. Previously, if all indexes were taken the kernel would overwrite 1188 only a core file with the highest index in a filename. 1189 Currently the system will create a new core file if there is a free 1190 index or if all slots are taken it will overwrite the oldest one. 1191 119220180630: 1193 Clang, llvm, lld, lldb, compiler-rt and libc++ have been upgraded to 1194 6.0.1. Please see the 20141231 entry below for information about 1195 prerequisites and upgrading, if you are not already using clang 3.5.0 1196 or higher. 1197 119820180628: 1199 r335753 introduced a new quoting method. However, etc/devd/devmatch.conf 1200 needed to be changed to work with it. This change was made with r335763 1201 and requires a mergemaster / etcupdate / etc to update the installed 1202 file. 1203 120420180612: 1205 r334930 changed the interface between the NFS modules, so they all 1206 need to be rebuilt. r335018 did a __FreeBSD_version bump for this. 1207 120820180530: 1209 As of r334391 lld is the default amd64 system linker; it is installed 1210 as /usr/bin/ld. Kernel build workarounds (see 20180510 entry) are no 1211 longer necessary. 1212 121320180530: 1214 The kernel / userland interface for devinfo changed, so you'll 1215 need a new kernel and userland as a pair for it to work (rebuilding 1216 lib/libdevinfo is all that's required). devinfo and devmatch will 1217 not work, but everything else will when there's a mismatch. 1218 121920180523: 1220 The on-disk format for hwpmc callchain records has changed to include 1221 threadid corresponding to a given record. This changes the field offsets 1222 and thus requires that libpmcstat be rebuilt before using a kernel 1223 later than r334108. 1224 122520180517: 1226 The vxge(4) driver has been removed. This driver was introduced into 1227 HEAD one week before the Exar left the Ethernet market and is not 1228 known to be used. If you have device vxge in your kernel config file 1229 it must be removed. 1230 123120180510: 1232 The amd64 kernel now requires a ld that supports ifunc to produce a 1233 working kernel, either lld or a newer binutils. lld is built by default 1234 on amd64, and the 'buildkernel' target uses it automatically. However, 1235 it is not the default linker, so building the kernel the traditional 1236 way requires LD=ld.lld on the command line (or LD=/usr/local/bin/ld for 1237 binutils port/package). lld will soon be default, and this requirement 1238 will go away. 1239 1240 NOTE: As of r334391 lld is the default system linker on amd64, and no 1241 workaround is necessary. 1242 124320180508: 1244 The nxge(4) driver has been removed. This driver was for PCI-X 10g 1245 cards made by s2io/Neterion. The company was acquired by Exar and 1246 no longer sells or supports Ethernet products. If you have device 1247 nxge in your kernel config file it must be removed. 1248 124920180504: 1250 The tz database (tzdb) has been updated to 2018e. This version more 1251 correctly models time stamps in time zones with negative DST such as 1252 Europe/Dublin (from 1971 on), Europe/Prague (1946/7), and 1253 Africa/Windhoek (1994/2017). This does not affect the UT offsets, only 1254 time zone abbreviations and the tm_isdst flag. 1255 125620180502: 1257 The ixgb(4) driver has been removed. This driver was for an early and 1258 uncommon legacy PCI 10GbE for a single ASIC, Intel 82597EX. Intel 1259 quickly shifted to the long lived ixgbe family. If you have device 1260 ixgb in your kernel config file it must be removed. 1261 126220180501: 1263 The lmc(4) driver has been removed. This was a WAN interface 1264 card that was already reportedly rare in 2003, and had an ambiguous 1265 license. If you have device lmc in your kernel config file it must 1266 be removed. 1267 126820180413: 1269 Support for Arcnet networks has been removed. If you have device 1270 arcnet or device cm in your kernel config file they must be 1271 removed. 1272 127320180411: 1274 Support for FDDI networks has been removed. If you have device 1275 fddi or device fpa in your kernel config file they must be 1276 removed. 1277 127820180406: 1279 In addition to supporting RFC 3164 formatted messages, the 1280 syslogd(8) service is now capable of parsing RFC 5424 formatted 1281 log messages. The main benefit of using RFC 5424 is that clients 1282 may now send log messages with timestamps containing year numbers, 1283 microseconds and time zone offsets. 1284 1285 Similarly, the syslog(3) C library function has been altered to 1286 send RFC 5424 formatted messages to the local system logging 1287 daemon. On systems using syslogd(8), this change should have no 1288 negative impact, as long as syslogd(8) and the C library are 1289 updated at the same time. On systems using a different system 1290 logging daemon, it may be necessary to make configuration 1291 adjustments, depending on the software used. 1292 1293 When using syslog-ng, add the 'syslog-protocol' flag to local 1294 input sources to enable parsing of RFC 5424 formatted messages: 1295 1296 source src { 1297 unix-dgram("/var/run/log" flags(syslog-protocol)); 1298 } 1299 1300 When using rsyslog, disable the 'SysSock.UseSpecialParser' option 1301 of the 'imuxsock' module to let messages be processed by the 1302 regular RFC 3164/5424 parsing pipeline: 1303 1304 module(load="imuxsock" SysSock.UseSpecialParser="off") 1305 1306 Do note that these changes only affect communication between local 1307 applications and syslogd(8). The format that syslogd(8) uses to 1308 store messages on disk or forward messages to other systems 1309 remains unchanged. syslogd(8) still uses RFC 3164 for these 1310 purposes. Options to customize this behaviour will be added in the 1311 future. Utilities that process log files stored in /var/log are 1312 thus expected to continue to function as before. 1313 1314 __FreeBSD_version has been incremented to 1200061 to denote this 1315 change. 1316 131720180328: 1318 Support for token ring networks has been removed. If you 1319 have "device token" in your kernel config you should remove 1320 it. No device drivers supported token ring. 1321 132220180323: 1323 makefs was modified to be able to tag ISO9660 El Torito boot catalog 1324 entries as EFI instead of overloading the i386 tag as done previously. 1325 The amd64 mkisoimages.sh script used to build amd64 ISO images for 1326 release was updated to use this. This may mean that makefs must be 1327 updated before "make cdrom" can be run in the release directory. This 1328 should be as simple as: 1329 1330 $ cd $SRCDIR/usr.sbin/makefs 1331 $ make depend all install 1332 133320180212: 1334 FreeBSD boot loader enhanced with Lua scripting. It's purely opt-in for 1335 now by building WITH_LOADER_LUA and WITHOUT_FORTH in /etc/src.conf. 1336 Co-existence for the transition period will come shortly. Booting is a 1337 complex environment and test coverage for Lua-enabled loaders has been 1338 thin, so it would be prudent to assume it might not work and make 1339 provisions for backup boot methods. 1340 134120180211: 1342 devmatch functionality has been turned on in devd. It will automatically 1343 load drivers for unattached devices. This may cause unexpected drivers 1344 to be loaded. Please report any problems to current@ and 1345 imp@freebsd.org. 1346 134720180114: 1348 Clang, llvm, lld, lldb, compiler-rt and libc++ have been upgraded to 1349 6.0.0. Please see the 20141231 entry below for information about 1350 prerequisites and upgrading, if you are not already using clang 3.5.0 1351 or higher. 1352 135320180110: 1354 LLVM's lld linker is now used as the FreeBSD/amd64 bootstrap linker. 1355 This means it is used to link the kernel and userland libraries and 1356 executables, but is not yet installed as /usr/bin/ld by default. 1357 1358 To revert to ld.bfd as the bootstrap linker, in /etc/src.conf set 1359 WITHOUT_LLD_BOOTSTRAP=yes 1360 136120180110: 1362 On i386, pmtimer has been removed. Its functionality has been folded 1363 into apm. It was a no-op on ACPI in current for a while now (but was 1364 still needed on i386 in FreeBSD 11 and earlier). Users may need to 1365 remove it from kernel config files. 1366 136720180104: 1368 The use of RSS hash from the network card aka flowid has been 1369 disabled by default for lagg(4) as it's currently incompatible with 1370 the lacp and loadbalance protocols. 1371 1372 This can be re-enabled by setting the following in loader.conf: 1373 net.link.lagg.default_use_flowid="1" 1374 137520180102: 1376 The SW_WATCHDOG option is no longer necessary to enable the 1377 hardclock-based software watchdog if no hardware watchdog is 1378 configured. As before, SW_WATCHDOG will cause the software 1379 watchdog to be enabled even if a hardware watchdog is configured. 1380 138120171215: 1382 r326887 fixes the issue described in the 20171214 UPDATING entry. 1383 r326888 flips the switch back to building GELI support always. 1384 138520171214: 1386 r362593 broke ZFS + GELI support for reasons unknown. However, 1387 it also broke ZFS support generally, so GELI has been turned off 1388 by default as the lesser evil in r326857. If you boot off ZFS and/or 1389 GELI, it might not be a good time to update. 1390 139120171125: 1392 PowerPC users must update loader(8) by rebuilding world before 1393 installing a new kernel, as the protocol connecting them has 1394 changed. Without the update, loader metadata will not be passed 1395 successfully to the kernel and users will have to enter their 1396 root partition at the kernel mountroot prompt to continue booting. 1397 Newer versions of loader can boot old kernels without issue. 1398 139920171110: 1400 The LOADER_FIREWIRE_SUPPORT build variable has been renamed to 1401 WITH/OUT_LOADER_FIREWIRE. LOADER_{NO_,}GELI_SUPPORT has been renamed 1402 to WITH/OUT_LOADER_GELI. 1403 140420171106: 1405 The naive and non-compliant support of posix_fallocate(2) in ZFS 1406 has been removed as of r325320. The system call now returns EINVAL 1407 when used on a ZFS file. Although the new behavior complies with the 1408 standard, some consumers are not prepared to cope with it. 1409 One known victim is lld prior to r325420. 1410 141120171102: 1412 Building in a FreeBSD src checkout will automatically create object 1413 directories now rather than store files in the current directory if 1414 'make obj' was not ran. Calling 'make obj' is no longer necessary. 1415 This feature can be disabled by setting WITHOUT_AUTO_OBJ=yes in 1416 /etc/src-env.conf (not /etc/src.conf), or passing the option in the 1417 environment. 1418 141920171101: 1420 The default MAKEOBJDIR has changed from /usr/obj/<srcdir> for native 1421 builds, and /usr/obj/<arch>/<srcdir> for cross-builds, to a unified 1422 /usr/obj/<srcdir>/<arch>. This behavior can be changed to the old 1423 format by setting WITHOUT_UNIFIED_OBJDIR=yes in /etc/src-env.conf, 1424 the environment, or with -DWITHOUT_UNIFIED_OBJDIR when building. 1425 The UNIFIED_OBJDIR option is a transitional feature that will be 1426 removed for 12.0 release; please migrate to the new format for any 1427 tools by looking up the OBJDIR used by 'make -V .OBJDIR' means rather 1428 than hardcoding paths. 1429 143020171028: 1431 The native-xtools target no longer installs the files by default to the 1432 OBJDIR. Use the native-xtools-install target with a DESTDIR to install 1433 to ${DESTDIR}/${NXTP} where NXTP defaults to /nxb-bin. 1434 143520171021: 1436 As part of the boot loader infrastructure cleanup, LOADER_*_SUPPORT 1437 options are changing from controlling the build if defined / undefined 1438 to controlling the build with explicit 'yes' or 'no' values. They will 1439 shift to WITH/WITHOUT options to match other options in the system. 1440 144120171010: 1442 libstand has turned into a private library for sys/boot use only. 1443 It is no longer supported as a public interface outside of sys/boot. 1444 144520171005: 1446 The arm port has split armv6 into armv6 and armv7. armv7 is now 1447 a valid TARGET_ARCH/MACHINE_ARCH setting. If you have an armv7 system 1448 and are running a kernel from before r324363, you will need to add 1449 MACHINE_ARCH=armv7 to 'make buildworld' to do a native build. 1450 145120171003: 1452 When building multiple kernels using KERNCONF, non-existent KERNCONF 1453 files will produce an error and buildkernel will fail. Previously 1454 missing KERNCONF files silently failed giving no indication as to 1455 why, only to subsequently discover during installkernel that the 1456 desired kernel was never built in the first place. 1457 145820170912: 1459 The default serial number format for CTL LUNs has changed. This will 1460 affect users who use /dev/diskid/* device nodes, or whose FibreChannel 1461 or iSCSI clients care about their LUNs' serial numbers. Users who 1462 require serial number stability should hardcode serial numbers in 1463 /etc/ctl.conf . 1464 146520170912: 1466 For 32-bit arm compiled for hard-float support, soft-floating point 1467 binaries now always get their shared libraries from 1468 LD_SOFT_LIBRARY_PATH (in the past, this was only used if 1469 /usr/libsoft also existed). Only users with a hard-float ld.so, but 1470 soft-float everything else should be affected. 1471 147220170826: 1473 The geli password typed at boot is now hidden. To restore the previous 1474 behavior, see geli(8) for configuration options. 1475 147620170825: 1477 Move PMTUD blackhole counters to TCPSTATS and remove them from bare 1478 sysctl values. Minor nit, but requires a rebuild of both world/kernel 1479 to complete. 1480 148120170814: 1482 "make check" behavior (made in ^/head@r295380) has been changed to 1483 execute from a limited sandbox, as opposed to executing from 1484 ${TESTSDIR}. 1485 1486 Behavioral changes: 1487 - The "beforecheck" and "aftercheck" targets are now specified. 1488 - ${CHECKDIR} (added in commit noted above) has been removed. 1489 - Legacy behavior can be enabled by setting 1490 WITHOUT_MAKE_CHECK_USE_SANDBOX in src.conf(5) or the environment. 1491 1492 If the limited sandbox mode is enabled, "make check" will execute 1493 "make distribution", then install, execute the tests, and clean up the 1494 sandbox if successful. 1495 1496 The "make distribution" and "make install" targets are typically run as 1497 root to set appropriate permissions and ownership at installation time. 1498 The end-user should set "WITH_INSTALL_AS_USER" in src.conf(5) or the 1499 environment if executing "make check" with limited sandbox mode using 1500 an unprivileged user. 1501 150220170808: 1503 Since the switch to GPT disk labels, fsck for UFS/FFS has been 1504 unable to automatically find alternate superblocks. As of r322297, 1505 the information needed to find alternate superblocks has been 1506 moved to the end of the area reserved for the boot block. 1507 Filesystems created with a newfs of this vintage or later 1508 will create the recovery information. If you have a filesystem 1509 created prior to this change and wish to have a recovery block 1510 created for your filesystem, you can do so by running fsck in 1511 foreground mode (i.e., do not use the -p or -y options). As it 1512 starts, fsck will ask ``SAVE DATA TO FIND ALTERNATE SUPERBLOCKS'' 1513 to which you should answer yes. 1514 151520170728: 1516 As of r321665, an NFSv4 server configuration that services 1517 Kerberos mounts or clients that do not support the uid/gid in 1518 owner/owner_group string capability, must explicitly enable 1519 the nfsuserd daemon by adding nfsuserd_enable="YES" to the 1520 machine's /etc/rc.conf file. 1521 152220170722: 1523 Clang, llvm, lldb, compiler-rt and libc++ have been upgraded to 5.0.0. 1524 Please see the 20141231 entry below for information about prerequisites 1525 and upgrading, if you are not already using clang 3.5.0 or higher. 1526 152720170701: 1528 WITHOUT_RCMDS is now the default. Set WITH_RCMDS if you need the 1529 r-commands (rlogin, rsh, etc.) to be built with the base system. 1530 153120170625: 1532 The FreeBSD/powerpc platform now uses a 64-bit type for time_t. This is 1533 a very major ABI incompatible change, so users of FreeBSD/powerpc must 1534 be careful when performing source upgrades. It is best to run 1535 'make installworld' from an alternate root system, either a live 1536 CD/memory stick, or a temporary root partition. Additionally, all ports 1537 must be recompiled. powerpc64 is largely unaffected, except in the case 1538 of 32-bit compatibility. All 32-bit binaries will be affected. 1539 154020170623: 1541 Forward compatibility for the "ino64" project have been committed. This 1542 will allow most new binaries to run on older kernels in a limited 1543 fashion. This prevents many of the common foot-shooting actions in the 1544 upgrade as well as the limited ability to roll back the kernel across 1545 the ino64 upgrade. Complicated use cases may not work properly, though 1546 enough simpler ones work to allow recovery in most situations. 1547 154820170620: 1549 Switch back to the BSDL dtc (Device Tree Compiler). Set WITH_GPL_DTC 1550 if you require the GPL compiler. 1551 155220170618: 1553 The internal ABI used for communication between the NFS kernel modules 1554 was changed by r320085, so __FreeBSD_version was bumped to 1555 ensure all the NFS related modules are updated together. 1556 155720170617: 1558 The ABI of struct event was changed by extending the data 1559 member to 64bit and adding ext fields. For upgrade, same 1560 precautions as for the entry 20170523 "ino64" must be 1561 followed. 1562 156320170531: 1564 The GNU roff toolchain has been removed from base. To render manpages 1565 which are not supported by mandoc(1), man(1) can fallback on GNU roff 1566 from ports (and recommends to install it). 1567 To render roff(7) documents, consider using GNU roff from ports or the 1568 heirloom doctools roff toolchain from ports via pkg install groff or 1569 via pkg install heirloom-doctools. 1570 157120170524: 1572 The ath(4) and ath_hal(4) modules now build piecemeal to allow for 1573 smaller runtime footprint builds. This is useful for embedded systems 1574 which only require one chipset support. 1575 1576 If you load it as a module, make sure this is in /boot/loader.conf: 1577 1578 if_ath_load="YES" 1579 1580 This will load the HAL, all chip/RF backends and if_ath_pci. 1581 If you have if_ath_pci in /boot/loader.conf, ensure it is after 1582 if_ath or it will not load any HAL chipset support. 1583 1584 If you want to selectively load things (eg on cheaper ARM/MIPS 1585 platforms where RAM is at a premium) you should: 1586 1587 * load ath_hal 1588 * load the chip modules in question 1589 * load ath_rate, ath_dfs 1590 * load ath_main 1591 * load if_ath_pci and/or if_ath_ahb depending upon your particular 1592 bus bind type - this is where probe/attach is done. 1593 1594 For further comments/feedback, poke adrian@ . 1595 159620170523: 1597 The "ino64" 64-bit inode project has been committed, which extends 1598 a number of types to 64 bits. Upgrading in place requires care and 1599 adherence to the documented upgrade procedure. 1600 1601 If using a custom kernel configuration ensure that the 1602 COMPAT_FREEBSD11 option is included (as during the upgrade the 1603 system will be running the ino64 kernel with the existing world). 1604 1605 For the safest in-place upgrade begin by removing previous build 1606 artifacts via "rm -rf /usr/obj/*". Then, carefully follow the full 1607 procedure documented below under the heading "To rebuild everything and 1608 install it on the current system." Specifically, a reboot is required 1609 after installing the new kernel before installing world. While an 1610 installworld normally works by accident from multiuser after rebooting 1611 the proper kernel, there are many cases where this will fail across this 1612 upgrade and installworld from single user is required. 1613 161420170424: 1615 The NATM framework including the en(4), fatm(4), hatm(4), and 1616 patm(4) devices has been removed. Consumers should plan a 1617 migration before the end-of-life date for FreeBSD 11. 1618 161920170420: 1620 GNU diff has been replaced by a BSD licensed diff. Some features of GNU 1621 diff has not been implemented, if those are needed a newer version of 1622 GNU diff is available via the diffutils package under the gdiff name. 1623 162420170413: 1625 As of r316810 for ipfilter, keep frags is no longer assumed when 1626 keep state is specified in a rule. r316810 aligns ipfilter with 1627 documentation in man pages separating keep frags from keep state. 1628 This allows keep state to be specified without forcing keep frags 1629 and allows keep frags to be specified independently of keep state. 1630 To maintain previous behaviour, also specify keep frags with 1631 keep state (as documented in ipf.conf.5). 1632 163320170407: 1634 arm64 builds now use the base system LLD 4.0.0 linker by default, 1635 instead of requiring that the aarch64-binutils port or package be 1636 installed. To continue using aarch64-binutils, set 1637 CROSS_BINUTILS_PREFIX=/usr/local/aarch64-freebsd/bin . 1638 163920170405: 1640 The UDP optimization in entry 20160818 that added the sysctl 1641 net.inet.udp.require_l2_bcast has been reverted. L2 broadcast 1642 packets will no longer be treated as L3 broadcast packets. 1643 164420170331: 1645 Binds and sends to the loopback addresses, IPv6 and IPv4, will now 1646 use any explicitly assigned loopback address available in the jail 1647 instead of using the first assigned address of the jail. 1648 164920170329: 1650 The ctl.ko module no longer implements the iSCSI target frontend: 1651 cfiscsi.ko does instead. 1652 1653 If building cfiscsi.ko as a kernel module, the module can be loaded 1654 via one of the following methods: 1655 - `cfiscsi_load="YES"` in loader.conf(5). 1656 - Add `cfiscsi` to `$kld_list` in rc.conf(5). 1657 - ctladm(8)/ctld(8), when compiled with iSCSI support 1658 (`WITH_ISCSI=yes` in src.conf(5)) 1659 1660 Please see cfiscsi(4) for more details. 1661 166220170316: 1663 The mmcsd.ko module now additionally depends on geom_flashmap.ko. 1664 Also, mmc.ko and mmcsd.ko need to be a matching pair built from the 1665 same source (previously, the dependency of mmcsd.ko on mmc.ko was 1666 missing, but mmcsd.ko now will refuse to load if it is incompatible 1667 with mmc.ko). 1668 166920170315: 1670 The syntax of ipfw(8) named states was changed to avoid ambiguity. 1671 If you have used named states in the firewall rules, you need to modify 1672 them after installworld and before rebooting. Now named states must 1673 be prefixed with colon. 1674 167520170311: 1676 The old drm (sys/dev/drm/) drivers for i915 and radeon have been 1677 removed as the userland we provide cannot use them. The KMS version 1678 (sys/dev/drm2) supports the same hardware. 1679 168020170302: 1681 Clang, llvm, lldb, compiler-rt and libc++ have been upgraded to 4.0.0. 1682 Please see the 20141231 entry below for information about prerequisites 1683 and upgrading, if you are not already using clang 3.5.0 or higher. 1684 168520170221: 1686 The code that provides support for ZFS .zfs/ directory functionality 1687 has been reimplemented. It's not possible now to create a snapshot 1688 by mkdir under .zfs/snapshot/. That should be the only user visible 1689 change. 1690 169120170216: 1692 EISA bus support has been removed. The WITH_EISA option is no longer 1693 valid. 1694 169520170215: 1696 MCA bus support has been removed. 1697 169820170127: 1699 The WITH_LLD_AS_LD / WITHOUT_LLD_AS_LD build knobs have been renamed 1700 WITH_LLD_IS_LD / WITHOUT_LLD_IS_LD, for consistency with CLANG_IS_CC. 1701 170220170112: 1703 The EM_MULTIQUEUE kernel configuration option is deprecated now that 1704 the em(4) driver conforms to iflib specifications. 1705 170620170109: 1707 The igb(4), em(4) and lem(4) ethernet drivers are now implemented via 1708 IFLIB. If you have a custom kernel configuration that excludes em(4) 1709 but you use igb(4), you need to re-add em(4) to your custom 1710 configuration. 1711 171220161217: 1713 Clang, llvm, lldb, compiler-rt and libc++ have been upgraded to 3.9.1. 1714 Please see the 20141231 entry below for information about prerequisites 1715 and upgrading, if you are not already using clang 3.5.0 or higher. 1716 171720161124: 1718 Clang, llvm, lldb, compiler-rt and libc++ have been upgraded to 3.9.0. 1719 Please see the 20141231 entry below for information about prerequisites 1720 and upgrading, if you are not already using clang 3.5.0 or higher. 1721 172220161119: 1723 The layout of the pmap structure has changed for powerpc to put the pmap 1724 statistics at the front for all CPU variations. libkvm(3) and all tools 1725 that link against it need to be recompiled. 1726 172720161030: 1728 isl(4) and cyapa(4) drivers now require a new driver, 1729 chromebook_platform(4), to work properly on Chromebook-class hardware. 1730 On other types of hardware the drivers may need to be configured using 1731 device hints. Please see the corresponding manual pages for details. 1732 173320161017: 1734 The urtwn(4) driver was merged into rtwn(4) and now consists of 1735 rtwn(4) main module + rtwn_usb(4) and rtwn_pci(4) bus-specific 1736 parts. 1737 Also, firmware for RTL8188CE was renamed due to possible name 1738 conflict (rtwnrtl8192cU(B) -> rtwnrtl8192cE(B)) 1739 174020161015: 1741 GNU rcs has been removed from base. It is available as packages: 1742 - rcs: Latest GPLv3 GNU rcs version. 1743 - rcs57: Copy of the latest version of GNU rcs (GPLv2) before it was 1744 removed from base. 1745 174620161008: 1747 Use of the cc_cdg, cc_chd, cc_hd, or cc_vegas congestion control 1748 modules now requires that the kernel configuration contain the 1749 TCP_HHOOK option. (This option is included in the GENERIC kernel.) 1750 175120161003: 1752 The WITHOUT_ELFCOPY_AS_OBJCOPY src.conf(5) knob has been retired. 1753 ELF Tool Chain's elfcopy is always installed as /usr/bin/objcopy. 1754 175520160924: 1756 Relocatable object files with the extension of .So have been renamed 1757 to use an extension of .pico instead. The purpose of this change is 1758 to avoid a name clash with shared libraries on case-insensitive file 1759 systems. On those file systems, foo.So is the same file as foo.so. 1760 176120160918: 1762 GNU rcs has been turned off by default. It can (temporarily) be built 1763 again by adding WITH_RCS knob in src.conf. 1764 Otherwise, GNU rcs is available from packages: 1765 - rcs: Latest GPLv3 GNU rcs version. 1766 - rcs57: Copy of the latest version of GNU rcs (GPLv2) from base. 1767 176820160918: 1769 The backup_uses_rcs functionality has been removed from rc.subr. 1770 177120160908: 1772 The queue(3) debugging macro, QUEUE_MACRO_DEBUG, has been split into 1773 two separate components, QUEUE_MACRO_DEBUG_TRACE and 1774 QUEUE_MACRO_DEBUG_TRASH. Define both for the original 1775 QUEUE_MACRO_DEBUG behavior. 1776 177720160824: 1778 r304787 changed some ioctl interfaces between the iSCSI userspace 1779 programs and the kernel. ctladm, ctld, iscsictl, and iscsid must be 1780 rebuilt to work with new kernels. __FreeBSD_version has been bumped 1781 to 1200005. 1782 178320160818: 1784 The UDP receive code has been updated to only treat incoming UDP 1785 packets that were addressed to an L2 broadcast address as L3 1786 broadcast packets. It is not expected that this will affect any 1787 standards-conforming UDP application. The new behaviour can be 1788 disabled by setting the sysctl net.inet.udp.require_l2_bcast to 1789 0. 1790 179120160818: 1792 Remove the openbsd_poll system call. 1793 __FreeBSD_version has been bumped because of this. 1794 179520160708: 1796 The stable/11 branch has been created from head@r302406. 1797 1798After branch N is created, entries older than the N-2 branch point are removed 1799from this file. After stable/14 is branched and current becomes FreeBSD 15, 1800entries older than stable/12 branch point will be removed from current's 1801UPDATING file. 1802 1803COMMON ITEMS: 1804 1805 General Notes 1806 ------------- 1807 Sometimes, obscure build problems are the result of environment 1808 poisoning. This can happen because the make utility reads its 1809 environment when searching for values for global variables. To run 1810 your build attempts in an "environmental clean room", prefix all make 1811 commands with 'env -i '. See the env(1) manual page for more details. 1812 Occasionally a build failure will occur with "make -j" due to a race 1813 condition. If this happens try building again without -j, and please 1814 report a bug if it happens consistently. 1815 1816 When upgrading from one major version to another it is generally best to 1817 upgrade to the latest code in the currently installed branch first, then 1818 do an upgrade to the new branch. This is the best-tested upgrade path, 1819 and has the highest probability of being successful. Please try this 1820 approach if you encounter problems with a major version upgrade. Since 1821 the stable 4.x branch point, one has generally been able to upgrade from 1822 anywhere in the most recent stable branch to head / current (or even the 1823 last couple of stable branches). See the top of this file when there's 1824 an exception. 1825 1826 The update process will emit an error on an attempt to perform a build 1827 or install from a FreeBSD version below the earliest supported version. 1828 When updating from an older version the update should be performed one 1829 major release at a time, including running `make delete-old` at each 1830 step. 1831 1832 When upgrading a live system, having a root shell around before 1833 installing anything can help undo problems. Not having a root shell 1834 around can lead to problems if pam has changed too much from your 1835 starting point to allow continued authentication after the upgrade. 1836 1837 This file should be read as a log of events. When a later event changes 1838 information of a prior event, the prior event should not be deleted. 1839 Instead, a pointer to the entry with the new information should be 1840 placed in the old entry. Readers of this file should also sanity check 1841 older entries before relying on them blindly. Authors of new entries 1842 should write them with this in mind. 1843 1844 ZFS notes 1845 --------- 1846 When upgrading the boot ZFS pool to a new version (via zpool upgrade), 1847 always follow these three steps: 1848 1849 1) recompile and reinstall the ZFS boot loader and boot block 1850 (this is part of "make buildworld" and "make installworld") 1851 1852 2) update the ZFS boot block on your boot drive (only required when 1853 doing a zpool upgrade): 1854 1855 When booting on x86 via BIOS, use the following to update the ZFS boot 1856 block on the freebsd-boot partition of a GPT partitioned drive ada0: 1857 gpart bootcode -p /boot/gptzfsboot -i $N ada0 1858 The value $N will typically be 1. For EFI booting, see EFI notes. 1859 1860 3) zpool upgrade the root pool. New bootblocks will work with old 1861 pools, but not vice versa, so they need to be updated before any 1862 zpool upgrade. 1863 1864 Non-boot pools do not need these updates. 1865 1866 EFI notes 1867 --------- 1868 1869 There are two locations the boot loader can be installed into. The 1870 current location (and the default) is \efi\freebsd\loader.efi and using 1871 efibootmgr(8) to configure it. The old location, that must be used on 1872 deficient systems that don't honor efibootmgr(8) protocols, is the 1873 fallback location of \EFI\BOOT\BOOTxxx.EFI. Generally, you will copy 1874 /boot/loader.efi to this location, but on systems installed a long time 1875 ago the ESP may be too small and /boot/boot1.efi may be needed unless 1876 the ESP has been expanded in the meantime. 1877 1878 Recent systems will have the ESP mounted on /boot/efi, but older ones 1879 may not have it mounted at all, or mounted in a different 1880 location. Older arm SD images with MBR used /boot/msdos as the 1881 mountpoint. The ESP is a MSDOS filesystem. 1882 1883 The EFI boot loader rarely needs to be updated. For ZFS booting, 1884 however, you must update loader.efi before you do 'zpool upgrade' the 1885 root zpool, otherwise the old loader.efi may reject the upgraded zpool 1886 since it does not automatically understand some new features. 1887 1888 See loader.efi(8) and uefi(8) for more details. 1889 1890 To build a kernel 1891 ----------------- 1892 If you are updating from a prior version of FreeBSD (even one just 1893 a few days old), you should follow this procedure. It is the most 1894 failsafe as it uses a /usr/obj tree with a fresh mini-buildworld, 1895 1896 make kernel-toolchain 1897 make -DALWAYS_CHECK_MAKE buildkernel KERNCONF=YOUR_KERNEL_HERE 1898 make -DALWAYS_CHECK_MAKE installkernel KERNCONF=YOUR_KERNEL_HERE 1899 1900 To test a kernel once 1901 --------------------- 1902 If you just want to boot a kernel once (because you are not sure 1903 if it works, or if you want to boot a known bad kernel to provide 1904 debugging information) run 1905 make installkernel KERNCONF=YOUR_KERNEL_HERE KODIR=/boot/testkernel 1906 nextboot -k testkernel 1907 1908 To rebuild everything and install it on the current system. 1909 ----------------------------------------------------------- 1910 # Note: sometimes if you are running current you gotta do more than 1911 # is listed here if you are upgrading from a really old current. 1912 1913 <make sure you have good level 0 dumps> 1914 make buildworld 1915 make buildkernel KERNCONF=YOUR_KERNEL_HERE 1916 make installkernel KERNCONF=YOUR_KERNEL_HERE 1917 [1] 1918 <reboot in single user> [3] 1919 etcupdate -p [5] 1920 make installworld 1921 etcupdate -B [4] 1922 make delete-old [6] 1923 <reboot> 1924 1925 To cross-install current onto a separate partition 1926 -------------------------------------------------- 1927 # In this approach we use a separate partition to hold 1928 # current's root, 'usr', and 'var' directories. A partition 1929 # holding "/", "/usr" and "/var" should be about 2GB in 1930 # size. 1931 1932 <make sure you have good level 0 dumps> 1933 <boot into -stable> 1934 make buildworld 1935 make buildkernel KERNCONF=YOUR_KERNEL_HERE 1936 <maybe newfs current's root partition> 1937 <mount current's root partition on directory ${CURRENT_ROOT}> 1938 make installworld DESTDIR=${CURRENT_ROOT} -DDB_FROM_SRC 1939 make distribution DESTDIR=${CURRENT_ROOT} # if newfs'd 1940 make installkernel KERNCONF=YOUR_KERNEL_HERE DESTDIR=${CURRENT_ROOT} 1941 cp /etc/fstab ${CURRENT_ROOT}/etc/fstab # if newfs'd 1942 <edit ${CURRENT_ROOT}/etc/fstab to mount "/" from the correct partition> 1943 <reboot into current> 1944 <do a "native" rebuild/install as described in the previous section> 1945 <maybe install compatibility libraries from ports/misc/compat*> 1946 <reboot> 1947 1948 1949 To upgrade in-place from stable to current 1950 ---------------------------------------------- 1951 <make sure you have good level 0 dumps> 1952 make buildworld [9] 1953 make buildkernel KERNCONF=YOUR_KERNEL_HERE [8] 1954 make installkernel KERNCONF=YOUR_KERNEL_HERE 1955 [1] 1956 <reboot in single user> [3] 1957 etcupdate -p [5] 1958 make installworld 1959 etcupdate -B [4] 1960 make delete-old [6] 1961 <reboot> 1962 1963 Make sure that you've read the UPDATING file to understand the 1964 tweaks to various things you need. At this point in the life 1965 cycle of current, things change often and you are on your own 1966 to cope. The defaults can also change, so please read ALL of 1967 the UPDATING entries. 1968 1969 Also, if you are tracking -current, you must be subscribed to 1970 freebsd-current@freebsd.org. Make sure that before you update 1971 your sources that you have read and understood all the recent 1972 messages there. If in doubt, please track -stable which has 1973 much fewer pitfalls. 1974 1975 [1] If you have third party modules, such as vmware, you should disable 1976 them at this point so they don't crash your system on 1977 reboot. Alternatively, you should rebuild all the modules you have in 1978 your system and install them as well. If you are running -current, you 1979 should seriously consider placing all sources to all the modules for 1980 your system (or symlinks to them) in /usr/local/sys/modules so this 1981 happens automatically. If all your modules come from ports, then adding 1982 the port origin directories to PORTS_MODULES instead is also automatic 1983 and effective, eg: 1984 PORTS_MODULES+=x11/nvidia-driver 1985 1986 [3] From the bootblocks, boot -s, and then do 1987 fsck -p 1988 mount -u / 1989 mount -a 1990 sh /etc/rc.d/zfs start # mount zfs filesystem, if needed 1991 cd src # full path to source 1992 adjkerntz -i # if CMOS is wall time 1993 Also, when doing a major release upgrade, it is required that you boot 1994 into single user mode to do the installworld. 1995 1996 [4] Note: This step is non-optional. Failure to do this step 1997 can result in a significant reduction in the functionality of the 1998 system. Attempting to do it by hand is not recommended and those 1999 that pursue this avenue should read this file carefully, as well 2000 as the archives of freebsd-current and freebsd-hackers mailing lists 2001 for potential gotchas. See etcupdate(8) for more information. 2002 2003 [5] Usually this step is a no-op. However, from time to time 2004 you may need to do this if you get unknown user in the following 2005 step. 2006 2007 [6] This only deletes old files and directories. Old libraries 2008 can be deleted by "make delete-old-libs", but you have to make 2009 sure that no program is using those libraries anymore. 2010 2011 [8] The new kernel must be able to run existing binaries used by an 2012 installworld. When upgrading across major versions, the new kernel's 2013 configuration must include the correct COMPAT_FREEBSD<n> option for 2014 existing binaries (e.g. COMPAT_FREEBSD11 to run 11.x binaries). Failure 2015 to do so may leave you with a system that is hard to boot to recover. A 2016 GENERIC kernel will include suitable compatibility options to run 2017 binaries from older branches. Note that the ability to run binaries 2018 from unsupported branches is not guaranteed. 2019 2020 Make sure that you merge any new devices from GENERIC since the 2021 last time you updated your kernel config file. Options also 2022 change over time, so you may need to adjust your custom kernels 2023 for these as well. 2024 2025 [9] If CPUTYPE is defined in your /etc/make.conf, make sure to use the 2026 "?=" instead of the "=" assignment operator, so that buildworld can 2027 override the CPUTYPE if it needs to. 2028 2029 MAKEOBJDIRPREFIX must be defined in an environment variable, and 2030 not on the command line, or in /etc/make.conf. buildworld will 2031 warn if it is improperly defined. 2032FORMAT: 2033 2034This file contains a list, in reverse chronological order, of major 2035breakages in tracking -current.
