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 3020231120: 31 If you have an arm64 system that uses ACPI, you will need to update your 32 loader.efi in the ESP when you update past this point. Detection of ACPI 33 was moved earlier in the binary so the scripts could use it, but old 34 binaries don't have this, so we default to 'no ACPI' in this case. You can 35 undisable ACPI by doing 36 OK unset hint.acpi.0.disabled 37 This can also be used to recover any other system that was updated in the 38 small window where amd64 was also broken. 39 4020231113: 41 The WITHOUT_LLD_IS_LD option has been removed. When LLD is enabled 42 it is always installed as /usr/bin/ld. 43 4420231027: 45 Forward compatibility (running the new code on old kernels) for the 46 "ino64" project have been removed. The need for it has passed long ago. 47 4820231018: 49 Commit 57ce37f9dcd0 changed the internal KAPI between the 50 nfscommon and nfscl modules. Both must be rebuilt from sources. 51 5220231010: 53 dialog(1) has been replaced in base by bsddialog(1), while most of the 54 time replacing a dialog(1) call by a bsddialog(1) call works out of the 55 box, bsddialog(1) is not considered as a drop-in replacement for 56 dialog(1). 57 58 If you do depend on dialog(1) functionality, please install cdialog 59 from ports: 60 61 pkg install cdialog 62 6320230927: 64 The EARLY_AP_STARTUP kernel option is mandatory on x86. The option 65 has been added to DEFAULTS, so it should automatically be included in 66 custom kernel configurations without any additional change. 67 6820230922: 69 A new loader tunable net.pf.default_to_drop allows pf(4)’s default 70 behaviour to be changed from pass to drop. Previously this required 71 recompiling the kernel with the option PF_DEFAULT_TO_DROP. 72 7320230914: 74 Enable splitting out pkgbase manpages into separate packages by 75 default. To disable this, set WITHOUT_MANSPLITPKG=yes in src.conf. 76 7720230911: 78 Move standard include files to the clibs-dev package and move clang 79 internal libraries and headers to clang and clang-dev. Upgrading systems 80 installed using pkgbase past this change involves extra steps to allow 81 for these file moves: 82 83 pkg upgrade -y FreeBSD-utilities 84 pkg upgrade -y FreeBSD-utilities-dev 85 pkg upgrade -y 86 8720230909: 88 Enable vnet sysctl variables to be loader tunable. SYSCTLs which 89 belongs to VNETs can be initialized during early boot or module 90 loading if they are marked with CTLFLAG_TUN and there are 91 corresponding kernel environment variables. 92 9320230901: 94 The WITH_INIT_ALL_PATTERN and WITH_INIT_ALL_ZERO build options have 95 been replaced by INIT_ALL=pattern and INIT_ALL=zero respectively. 96 9720230824: 98 FreeBSD 15.0-CURRENT. 99 10020230817: 101 Serial communication (in boot loaders, kernel, and userland) has 102 been changed to default to 115200 bps, in line with common industry 103 practice and typcial firmware serial console redirection 104 configuration. 105 106 Note that the early x86 BIOS bootloader (i.e., boot0sio) does not 107 support rates above 9600 bps and is not changed. boot0sio users may 108 set BOOT_COMCONSOLE_SPEED=9600 to use 9600 for all of the boot 109 components, or use the standard boot0 and have the boot2 stage start 110 with the serial port at 115200. 111 11220230807: 113 Following the general removal of MIPS support, the ath(4) AHB bus- 114 frontend has been removed, too, and building of the PCI support is 115 integrated with the ath(4) main module again. As a result, there's 116 no longer a need for if_ath_pci_load="YES" in /boot/loader.conf or 117 "device ath_pci" in the kernel configuration. 118 11920230803: 120 MAXCPU has been increased to 1024 in the amd64 GENERIC kernel config. 121 Out-of-tree kernel modules will need to be rebuilt. 122 12320230724: 124 CAM has been mechanically updated s/u_int(64|32|16|8)_t/uint\1_t/g 125 to move to the standard uintXX_t types from the old, traditional 126 BSD u_intXX_t types. This should be a NOP, but may cause problems 127 for out of tree changes. The SIMs were not updated since most of 128 the old u_intXX_t uses weren't due to CAM interfaces. 129 13020230713: 131 stable/14 branch created. 132 13320230629: 134 The heuristic for detecting old chromebooks with an EC bug that requires 135 atkbdc driver workarounds has changed. There should be no functional 136 change, but if your old chromebook's keyboard stops working, please 137 file a PR and assign it to imp. 138 13920230623: 140 OpenSSL has been updated to version 3.0, including changes throughout 141 the base system. It is important to rebuild third-party software 142 after upgrading. 143 14420230619: 145 To enable pf rdr rules for connections initiated from the host, pf 146 filter rules can be optionally enabled for packets delivered 147 locally. This can change the behavior of rules which match packets 148 delivered to lo0. To enable this feature: 149 150 sysctl net.pf.filter_local=1 151 service pf restart 152 153 When enabled, its best to ensure that packets delivered locally are not 154 filtered, e.g. by adding a 'skip on lo' rule. 155 15620230613: 157 Improvements to libtacplus(8) mean that tacplus.conf(5) now 158 follows POSIX shell syntax rules. This may cause TACACS+ 159 authentication to fail if the shared secret contains a single 160 quote, double quote, or backslash character which isn't 161 already properly quoted or escaped. 162 16320230612: 164 Belatedly switch the default nvme block device on x86 from nvd to nda. 165 nda created nvd compatibility links by default, so this should be a 166 nop. If this causes problems for your application, set hw.nvme.use_nvd=1 167 in your loader.conf or add `options NVME_USE_NVD=1` to your kernel 168 config. To disable the nvd compatibility aliases, add 169 kern.cam.nda.nvd_compat=0 to loader.conf. The default has been nda on 170 all non-x86 platforms for some time now. If you need to fall back, 171 please email imp@freebsd.org about why. 172 173 Encrypted swap partitions need to be changed from nvd to nda if you 174 migrate, or you need to use the above to switch back to nvd. 175 17620230422: 177 Remove portsnap(8). Users are encouraged to obtain the ports tree 178 using git instead. 179 18020230420: 181 Add jobs.mk to save typing. Enables -j${JOB_MAX} and logging 182 eg. 183 make buildworld-jobs 184 runs 185 make -j${JOB_MAX} buildworld > ../buildworld.log 2>&1 186 187 where JOB_MAX is derrived from ncpus in local.sys.mk if not set in env. 188 18920230316: 190 Video related devices for some arm devices have been renamed. 191 If you have a custom kernel config and want to use hdmi output on 192 IMX6 board you need to add "device dwc_hdmi" "device imx6_hdmi" and 193 "device imx6_ipu" to it. 194 If you have a custom kernel config and want to use hdmi output on 195 TI AM335X board you need to add "device tda19988" to it. 196 If you add "device hdmi" in it you need to remove it as it doesn't 197 exist anymore. 198 19920230221: 200 Introduce new kernel options KBD_DELAY1 and KBD_DELAY2. See atkbdc(4) 201 for details. 202 20320230206: 204 sshd now defaults to having X11Forwarding disabled, following upstream. 205 Administrators who wish to enable X11Forwarding should add 206 `X11Forwarding yes` to /etc/ssh/sshd_config. 207 20820230204: 209 Since commit 75d41cb6967 Huawei 3G/4G LTE Mobile Devices do not default 210 to ECM, but NCM mode and need u3g and ucom modules loaded. See cdce(4). 211 21220230130: 213 As of commit 7c40e2d5f685, the dependency on netlink(4) has been added 214 to the linux_common(4) module. Users relying on linux_common may need 215 to complile netlink(4) module if it is not present in their kernel. 216 21720230126: 218 The WITHOUT_CXX option has been removed. C++ components in the base 219 system are now built unconditionally. 220 22120230113: 222 LinuxKPI pci.h changes may require out-of-tree drivers to be recompiled. 223 Bump _FreeBSD_version to 1400078 to be able to detect this change. 224 22520221212: 226 llvm-objump is now always installed as objdump. Previously there was 227 no /usr/bin/objdump unless the WITH_LLVM_BINUTILS knob was used. 228 229 Some LLVM objdump options have a different output format compared to 230 GNU objdump; readelf is available for inspecting ELF files, and GNU 231 objdump is available from the devel/binutils port or package. 232 23320221205: 234 dma(8) has replaced sendmail(8) as the default mta. For people willing 235 to reenable sendmail(8): 236 237 $ cp /usr/share/examples/sendmail/mailer.conf /etc/mail/mailer.conf 238 239 and add sendmail_enable="YES" to rc.conf. 240 24120221204: 242 hw.bus.disable_failed_devices has changed from 'false' to 'true' by 243 default. Now if newbus succeeds in probing a device, but fails to attach 244 the device, we'll disable the device. In the past, we'd keep retrying 245 the device on each new driver loaded. To get that behavior now, one 246 needs to use devctl to re-enable the device, and reprobe it (or set 247 the sysctl/tunable hw.bus.disable_failed_devices=false). 248 249 NOTE: This was reverted 20221205 due to unexpected compatibility issues 250 25120221122: 252 pf no longer accepts 'scrub fragment crop' or 'scrub fragment drop-ovl'. 253 These configurations are no longer automatically reinterpreted as 254 'scrub fragment reassemble'. 255 25620221121: 257 The WITHOUT_CLANG_IS_CC option has been removed. When Clang is enabled 258 it is always installed as /usr/bin/cc (and c++, cpp). 259 26020221026: 261 Some programs have been moved into separate packages. It is recommended 262 for pkgbase users to do: 263 264 pkg install FreeBSD-dhclient FreeBSD-geom FreeBSD-resolvconf \ 265 FreeBSD-devd FreeBSD-devmatch 266 267 after upgrading to restore all the component that were previously 268 installed. 269 27020221002: 271 OPIE has been removed from the base system. If needed, it can 272 be installed from ports (security/opie) or packages (opie). 273 Otherwise, make sure that your PAM policies do not reference 274 pam_opie or pam_opieaccess. 275 27620220610: 277 LinuxKPI pm.h changes require an update to the latest drm-kmod version 278 before re-compiling to avoid errors. 279 28020211230: 281 The macros provided for the manipulation of CPU sets (e.g. CPU_AND) 282 have been modified to take 2 source arguments instead of only 1. 283 Externally maintained sources that use these macros will have to 284 be adapted. The FreeBSD version has been bumped to 1400046 to 285 reflect this change. 286 28720211214: 288 A number of the kernel include files are able to be included by 289 themselves. A test has been added to buildworld to enforce this. 290 29120211209: 292 Remove mips as a recognized target. This starts the decommissioning of 293 mips support in FreeBSD. mips related items will be removed wholesale in 294 the coming days and weeks. 295 296 This broke the NO_CLEAN build for some people. Either do a clean build 297 or touch 298 lib/clang/include/llvm/Config/Targets.def 299 lib/clang/include/llvm/Config/AsmParsers.def 300 lib/clang/include/llvm/Config/Disassemblers.def 301 lib/clang/include/llvm/Config/AsmPrinters.def 302 before the build to force everything to rebuild that needs to. 303 30420211202: 305 Unbound support for RFC8375: The special-use domain 'home.arpa' is 306 by default blocked. To unblock it use a local-zone nodefault 307 statement in unbound.conf: 308 local-zone: "home.arpa." nodefault 309 310 Or use another type of local-zone to override with your choice. 311 312 The reason for this is discussed in Section 6.1 of RFC8375: 313 Because 'home.arpa.' is not globally scoped and cannot be secured 314 using DNSSEC based on the root domain's trust anchor, there is no way 315 to tell, using a standard DNS query, in which homenet scope an answer 316 belongs. Consequently, users may experience surprising results with 317 such names when roaming to different homenets. 318 31920211110: 320 Commit b8d60729deef changed the TCP congestion control framework so 321 that any of the included congestion control modules could be 322 the single module built into the kernel. Previously newreno 323 was automatically built in through direct reference. As of 324 this commit you are required to declare at least one congestion 325 control module (e.g. 'options CC_NEWRENO') and to also declare a 326 default using the CC_DEFAULT option (e.g. options CC_DEFAULT="newreno\"). 327 The GENERIC configuration includes CC_NEWRENO and defines newreno 328 as the default. If no congestion control option is built into the 329 kernel and you are including networking, the kernel compile will 330 fail. Also if no default is declared the kernel compile will fail. 331 33220211118: 333 Mips has been removed from universe builds. It will be removed from the 334 tree shortly. 335 33620211106: 337 Commit f0c9847a6c47 changed the arguments for VOP_ALLOCATE. 338 The NFS modules must be rebuilt from sources and any out 339 of tree file systems that implement their own VOP_ALLOCATE 340 may need to be modified. 341 34220211022: 343 The synchronous PPP kernel driver sppp(4) has been removed. 344 The cp(4) and ce(4) drivers are now always compiled with netgraph(4) 345 support, formerly enabled by NETGRAPH_CRONYX option. 346 34720211020: 348 sh(1) is now the default shell for the root user. To force root to use 349 the csh shell, please run the following command as root: 350 351 # chsh -s csh 352 35320211004: 354 Ncurses distribution has been split between libtinfow and libncurses 355 with libncurses.so becoming a linker (ld) script to seamlessly link 356 to libtinfow as needed. Bump _FreeBSD_version to 1400035 to reflect 357 this change. 358 35920210923: 360 As of commit 8160a0f62be6, the dummynet module no longer depends on the 361 ipfw module. Dummynet can now be used by pf as well as ipfw. As such 362 users who relied on this dependency may need to include ipfw in the 363 list of modules to load on their systems. 364 36520210922: 366 As of commit 903873ce1560, the mixer(8) utility has got a slightly 367 new syntax. Please refer to the mixer(8) manual page for more 368 information. The old mixer utility can be installed from ports: 369 audio/freebsd-13-mixer 370 37120210911: 372 As of commit 55089ef4f8bb, the global variable nfs_maxcopyrange has 373 been deleted from the nfscommon.ko. As such, nfsd.ko must be built 374 from up to date sources to avoid an undefined reference when 375 being loaded. 376 37720210817: 378 As of commit 62ca9fc1ad56 OpenSSL no longer enables kernel TLS 379 by default. Users can enable kernel TLS via the "KTLS" SSL 380 option. This can be enabled globally by using a custom 381 OpenSSL config file via OPENSSL_CONF or via an 382 application-specific configuration option for applications 383 which permit setting SSL options via SSL_CONF_cmd(3). 384 38520210811: 386 Commit 3ad1e1c1ce20 changed the internal KAPI between the NFS 387 modules. Therefore, all need to be rebuilt from sources. 388 38920210730: 390 Commit b69019c14cd8 removes pf's DIOCGETSTATESNV ioctl. 391 As of be70c7a50d32 it is no longer used by userspace, but it does mean 392 users may not be able to enumerate pf states if they update the kernel 393 past b69019c14cd8 without first updating userspace past be70c7a50d32. 394 39520210729: 396 As of commit 01ad0c007964 if_bridge member interfaces can no longer 397 change their MTU. Changing the MTU of the bridge itself will change the 398 MTU on all member interfaces instead. 399 40020210716: 401 Commit ee29e6f31111 changed the internal KAPI between the nfscommon 402 and nfsd modules. Therefore, both need to be rebuilt from sources. 403 Bump __FreeBSD_version to 1400026 for this KAPI change. 404 40520210715: 406 The 20210707 awk update brought in a change in behavior. This has 407 been corrected as of d4d252c49976. Between these dates, if you 408 installed a new awk binary, you may not be able to build a new 409 kernel because the change in behavior affected the genoffset 410 script used to build the kernel. If you did update, the fix is 411 to update your sources past the above hash and do 412 % cd usr.bin/awk 413 % make clean all 414 % sudo -E make install 415 to enable building kernels again. 416 41720210708: 418 Commit 1e0a518d6548 changed the internal KAPI between the NFS 419 modules. They all need to be rebuilt from sources. I did not 420 bump __FreeBSD_version, since it was bumped recently. 421 42220210707: 423 awk has been updated to the latest one-true-awk version 20210215. 424 This contains a number of minor bug fixes. 425 42620210624: 427 The NFSv4 client now uses the highest minor version of NFSv4 428 supported by the NFSv4 server by default instead of minor version 0, 429 for NFSv4 mounts. 430 The "minorversion" mount option may be used to override this default. 431 43220210618: 433 Bump __FreeBSD_version to 1400024 for LinuxKPI changes. 434 Most notably netdev.h can change now as the (last) dependencies 435 (mlx4/ofed) are now using struct ifnet directly, but also for PCI 436 additions and others. 437 43820210618: 439 The directory "blacklisted" under /usr/share/certs/ has been 440 renamed to "untrusted". 441 44220210611: 443 svnlite has been removed from base. Should you need svn for any reason 444 please install the svn package or port. 445 44620210611: 447 Commit e1a907a25cfa changed the internal KAPI between the krpc 448 and nfsserver. As such, both modules must be rebuilt from 449 sources. Bump __FreeBSD_version to 1400022. 450 45120210610: 452 The an(4) driver has been removed from FreeBSD. 453 45420210608: 455 The vendor/openzfs branch was renamed to vendor/openzfs/legacy to 456 start tracking OpenZFS upstream more closely. Please see 457https://lists.freebsd.org/archives/freebsd-current/2021-June/000153.html 458 for details on how to correct any errors that might result. The 459 short version is that you need to remove the old branch locally: 460 git update-ref -d refs/remotes/freebsd/vendor/openzfs 461 (assuming your upstream origin is named 'freebsd'). 462 46320210525: 464 Commits 17accc08ae15 and de102f870501 add new files to LinuxKPI 465 which break drm-kmod. In addition various other additions where 466 committed. Bump __FreeBSD_version to 1400015 to be able to 467 detect this. 468 46920210513: 470 Commit ca179c4d74f2 changed the package in which the OpenSSL 471 libraries and utilities are packaged. 472 It is recommended for pkgbase user to do: 473 pkg install -f FreeBSD-openssl 474 before pkg upgrade otherwise some dependencies might not be met 475 and pkg will stop working as libssl will not be present anymore 476 on the system. 477 47820210426: 479 Commit 875977314881 changed the internal KAPI between 480 the nfsd and nfscommon modules. As such these modules 481 need to be rebuilt from sources. 482 Without this patch in your NFSv4.1/4.2 server, enabling 483 delegations by setting vfs.nfsd.issue_delegations non-zero 484 is not recommended. 485 48620210411: 487 Commit 7763814fc9c2 changed the internal KAPI between 488 the krpc and NFS. As such, the krpc, nfscommon and 489 nfscl modules must all be rebuilt from sources. 490 Without this patch, NFSv4.1/4.2 mounts should not 491 be done with the nfscbd(8) daemon running, to avoid 492 needing a working back channel for server->client RPCs. 493 49420210330: 495 Commit 01ae8969a9ee fixed the NFSv4.1/4.2 server so that it 496 handles binding of the back channel as required by RFC5661. 497 Until this patch is in your server, avoid use of the "nconnects" 498 mount option for Linux NFSv4.1/4.2 mounts. 499 50020210225: 501 For 64-bit architectures the base system is now built with Position 502 Independent Executable (PIE) support enabled by default. It may be 503 disabled using the WITHOUT_PIE knob. A clean build is required. 504 50520210128: 506 Various LinuxKPI functionality was added which conflicts with DRM. 507 Please update your drm-kmod port to after the __FreeBSD_version 1400003 508 update. 509 51020210121: 511 stable/13 branch created. 512 51320210108: 514 PC Card attachments for all devices have been removed. In the case of 515 wi and cmx, the entire drivers were removed because they were only 516 PC Card devices. FreeBSD_version 1300134 should be used for this 517 since it was bumped so recently. 518 51920210107: 520 Transport-independent parts of HID support have been split off the USB 521 code in to separate subsystem. Kernel configs which include one of 522 ums, ukbd, uhid, atp, wsp, wmt, uaudio, ugold or ucycom drivers should 523 be updated with adding of "device hid" line. 524 52520210105: 526 ncurses installation has been modified to only keep the widechar 527 enabled version. Incremental build is broken for that change, so it 528 requires a clean build. 529 53020201223: 531 The FreeBSD project has migrated from Subversion to Git. Temporary 532 instructions can be found at 533 https://github.com/bsdimp/freebsd-git-docs/blob/main/src-cvt.md 534 and other documents in that repo. 535 53620201216: 537 The services database has been updated to cover more of the basic 538 services expected in a modern system. The database is big enough 539 that it will cause issues in mergemaster in Releases previous to 540 12.2 and 11.3, or in very old current systems from before r358154. 541 54220201215: 543 Obsolete in-tree GDB 6.1.1 has been removed. GDB (including kgdb) 544 may be installed from ports or packages. 545 54620201124: 547 ping6 has been merged into ping. It can now be called as "ping -6". 548 See ping(8) for details. 549 55020201108: 551 Default value of net.add_addr_allfibs has been changed to 0. 552 If you have multi-fib configuration and rely on existence of all 553 interface routes in every fib, you need to set the above sysctl to 1. 554 55520201030: 556 The internal pre-processor in the calendar(1) program has been 557 extended to support more C pre-processor commands (e.g. #ifdef, #else, 558 and #undef) and to detect unbalanced conditional statements. 559 Error messages have been extended to include the filename and line 560 number if processing stops to help fixing malformed data files. 561 56220201026: 563 All the data files for the calendar(1) program, except calendar.freebsd, 564 have been moved to the deskutils/calendar-data port, much like the 565 jewish calendar entries were moved to deskutils/hebcal years ago. After 566 make delete-old-files, you need to install it to retain full 567 functionality. calendar(1) will issue a reminder for files it can't 568 find. 569 57020200923: 571 LINT files are no longer generated. We now include the relevant NOTES 572 files. Note: This may cause conflicts with updating in some cases. 573 find sys -name LINT\* -delete 574 is suggested across this commit to remove the generated LINT files. 575 576 If you have tried to update with generated files there, the svn 577 command you want to un-auger the tree is 578 cd sys/amd64/conf 579 svn revert -R . 580 and then do the above find from the top level. Substitute 'amd64' 581 above with where the error message indicates a conflict. 582 58320200824: 584 OpenZFS support has been integrated. Do not upgrade root pools until 585 the loader is updated to support zstd. Furthermore, we caution against 586 'zpool upgrade' for the next few weeks. The change should be transparent 587 unless you want to use new features. 588 589 Not all "NO_CLEAN" build scenarios work across these changes. Many 590 scenarios have been tested and fixed, but rebuilding kernels without 591 rebuilding world may fail. 592 593 The ZFS cache file has moved from /boot to /etc to match the OpenZFS 594 upstream default. A fallback to /boot has been added for mountroot. 595 596 Pool auto import behavior at boot has been moved from the kernel module 597 to an explicit "zpool import -a" in one of the rc scripts enabled by 598 zfs_enable=YES. This means your non-root zpools won't auto import until 599 you upgrade your /etc/rc.d files. 600 60120200824: 602 The resume code now notifies devd with the 'kernel' system 603 rather than the old 'kern' subsystem to be consistent with 604 other use. The old notification will be created as well, but 605 will be removed prior to FreeBSD 14.0. 606 60720200821: 608 r362275 changed the internal API between the kernel RPC and the 609 NFS modules. As such, all the modules must be recompiled from 610 sources. 611 61220200817: 613 r364330 modified the internal API used between the NFS modules. 614 As such, all the NFS modules must be re-compiled from sources. 615 61620200816: 617 Clang, llvm, lld, lldb, compiler-rt, libc++, libunwind and openmp have 618 been upgraded to 11.0.0. Please see the 20141231 entry below for 619 information about prerequisites and upgrading, if you are not already 620 using clang 3.5.0 or higher. 621 62220200810: 623 r364092 modified the internal ABI used between the kernel NFS 624 modules. As such, all of these modules need to be rebuilt 625 from sources, so a version bump was done. 626 62720200807: 628 Makefile.inc has been updated to work around the issue documented in 629 20200729. It was a case where the optimization of using symbolic links 630 to point to binaries created a situation where we'd run new binaries 631 with old libraries starting midway through the installworld process. 632 63320200729: 634 r363679 has redefined some undefined behavior in regcomp(3); notably, 635 extraneous escapes of most ordinary characters will no longer be 636 accepted. An exp-run has identified all of the problems with this in 637 ports, but other non-ports software may need extra escapes removed to 638 continue to function. 639 640 Because of this change, installworld may encounter the following error 641 from rtld: Undefined symbol "regcomp@FBSD_1.6" -- It is imperative that 642 you do not halt installworld. Instead, let it run to completion (whether 643 successful or not) and run installworld once more. 644 64520200627: 646 A new implementation of bc and dc has been imported in r362681. This 647 implementation corrects non-conformant behavior of the previous bc 648 and adds GNU bc compatible options. It offers a number of extensions, 649 is much faster on large values, and has support for message catalogs 650 (a number of languages are already supported, contributions of further 651 languages welcome). The option WITHOUT_GH_BC can be used to build the 652 world with the previous versions of bc and dc. 653 65420200625: 655 r362639 changed the internal API used between the NFS kernel modules. 656 As such, they all need to be rebuilt from sources. 657 65820200613: 659 r362158 changed the arguments for VFS_CHECKEXP(). As such, any 660 out of tree file systems need to be modified and rebuilt. 661 Also, any file systems that are modules must be rebuilt. 662 66320200604: 664 read(2) of a directory fd is now rejected by default. root may 665 re-enable it for system root only on non-ZFS filesystems with the 666 security.bsd.allow_read_dir sysctl(8) MIB if 667 security.bsd.suser_enabled=1. 668 669 It may be advised to setup aliases for grep to default to `-d skip` if 670 commonly non-recursively grepping a list that includes directories and 671 the potential for the resulting stderr output is not tolerable. Example 672 aliases are now installed, commented out, in /root/.cshrc and 673 /root/.shrc. 674 67520200523: 676 Clang, llvm, lld, lldb, compiler-rt, libc++, libunwind and openmp have 677 been upgraded to 10.0.1. Please see the 20141231 entry below for 678 information about prerequisites and upgrading, if you are not already 679 using clang 3.5.0 or higher. 680 68120200512: 682 Support for obsolete compilers has been removed from the build system. 683 Clang 6 and GCC 6.4 are the minimum supported versions. 684 68520200424: 686 closefrom(2) has been moved under COMPAT12, and replaced in libc with a 687 stub that calls close_range(2). If using a custom kernel configuration, 688 you may want to ensure that the COMPAT_FREEBSD12 option is included, as 689 a slightly older -CURRENT userland and older FreeBSD userlands may not 690 be functional without closefrom(2). 691 69220200414: 693 Upstream DTS from Linux 5.6 was merged and they now have the SID 694 and THS (Secure ID controller and THermal Sensor) node present. 695 The DTB overlays have now been removed from the tree for the H3/H5 and 696 A64 SoCs and the aw_sid and aw_thermal driver have been updated to 697 deal with upstream DTS. If you are using those overlays you need to 698 remove them from loader.conf and update the DTBs on the FAT partition. 699 70020200310: 701 Clang, llvm, lld, lldb, compiler-rt, libc++, libunwind and openmp have 702 been upgraded to 10.0.0. Please see the 20141231 entry below for 703 information about prerequisites and upgrading, if you are not already 704 using clang 3.5.0 or higher. 705 70620200309: 707 The amd(8) automount daemon has been removed from the source tree. 708 As of FreeBSD 10.1 autofs(5) is the preferred tool for automounting. 709 amd is still available in the sysutils/am-utils port. 710 71120200301: 712 Removed brooktree driver (bktr.4) from the tree. 713 71420200229: 715 The WITH_GPL_DTC option has been removed. The BSD-licenced device tree 716 compiler in usr.bin/dtc is used on all architectures which use dtc, and 717 the GPL dtc is available (if needed) from the sysutils/dtc port. 718 71920200229: 720 The WITHOUT_LLVM_LIBUNWIND option has been removed. LLVM's libunwind 721 is used by all supported CPU architectures. 722 72320200229: 724 GCC 4.2.1 has been removed from the tree. The WITH_GCC, 725 WITH_GCC_BOOTSTRAP, and WITH_GNUCXX options are no longer available. 726 Users who wish to build FreeBSD with GCC must use the external toolchain 727 ports or packages. 728 72920200220: 730 ncurses has been updated to a newer version (6.2-20200215). Given the ABI 731 has changed, users will have to rebuild all the ports that are linked to 732 ncurses. 733 73420200217: 735 The size of struct vnet and the magic cookie have changed. 736 Users need to recompile libkvm and all modules using VIMAGE 737 together with their new kernel. 738 73920200212: 740 Defining the long deprecated NO_CTF, NO_DEBUG_FILES, NO_INSTALLLIB, 741 NO_MAN, NO_PROFILE, and NO_WARNS variables is now an error. Update 742 your Makefiles and scripts to define MK_<var>=no instead as required. 743 744 One exception to this is that program or library Makefiles should 745 define MAN to empty rather than setting MK_MAN=no. 746 74720200108: 748 Clang/LLVM is now the default compiler and LLD the default 749 linker for riscv64. 750 75120200107: 752 make universe no longer uses GCC 4.2.1 on any architectures. 753 Architectures not supported by in-tree Clang/LLVM require an 754 external toolchain package. 755 75620200104: 757 GCC 4.2.1 is now not built by default, as part of the GCC 4.2.1 758 retirement plan. Specifically, the GCC, GCC_BOOTSTRAP, and GNUCXX 759 options default to off for all supported CPU architectures. As a 760 short-term transition aid they may be enabled via WITH_* options. 761 GCC 4.2.1 is expected to be removed from the tree on 2020-03-31. 762 76320200102: 764 Support for armv5 has been disconnected and is being removed. The 765 machine combination MACHINE=arm MACHINE_ARCH=arm is no longer valid. 766 You must now use a MACHINE_ARCH of armv6 or armv7. The default 767 MACHINE_ARCH for MACHINE=arm is now armv7. 768 76920191226: 770 Clang/LLVM is now the default compiler for all powerpc architectures. 771 LLD is now the default linker for powerpc64. The change for powerpc64 772 also includes a change to the ELFv2 ABI, incompatible with the existing 773 ABI. 774 77520191226: 776 Kernel-loadable random(4) modules are no longer unloadable. 777 77820191222: 779 Clang, llvm, lld, lldb, compiler-rt, libc++, libunwind and openmp have 780 been upgraded to 9.0.1. Please see the 20141231 entry below for 781 information about prerequisites and upgrading, if you are not already 782 using clang 3.5.0 or higher. 783 78420191212: 785 r355677 has modified the internal interface used between the 786 NFS modules in the kernel. As such, they must all be upgraded 787 simultaneously. I will do a version bump for this. 788 78920191205: 790 The root certificates of the Mozilla CA Certificate Store have been 791 imported into the base system and can be managed with the certctl(8) 792 utility. If you have installed the security/ca_root_nss port or package 793 with the ETCSYMLINK option (the default), be advised that there may be 794 differences between those included in the port and those included in 795 base due to differences in nss branch used as well as general update 796 frequency. Note also that certctl(8) cannot manage certs in the 797 format used by the security/ca_root_nss port. 798 79920191120: 800 The amd(8) automount daemon has been disabled by default, and will be 801 removed in the future. As of FreeBSD 10.1 the autofs(5) is available 802 for automounting. 803 80420191107: 805 The nctgpio and wbwd drivers have been moved to the superio bus. 806 If you have one of these drivers in a kernel configuration, then 807 you should add device superio to it. If you use one of these drivers 808 as a module and you compile a custom set of modules, then you should 809 add superio to the set. 810 81120191021: 812 KPIs for network drivers to access interface addresses have changed. 813 Users need to recompile NIC driver modules together with kernel. 814 81520191021: 816 The net.link.tap.user_open sysctl no longer prevents user opening of 817 already created /dev/tapNN devices. Access is still controlled by 818 node permissions, just like tun devices. The net.link.tap.user_open 819 sysctl is now used only to allow users to perform devfs cloning of 820 tap devices, and the subsequent open may not succeed if the user is not 821 in the appropriate group. This sysctl may be deprecated/removed 822 completely in the future. 823 82420191009: 825 mips, powerpc, and sparc64 are no longer built as part of 826 universe / tinderbox unless MAKE_OBSOLETE_GCC is defined. If 827 not defined, mips, powerpc, and sparc64 builds will look for 828 the xtoolchain binaries and if installed use them for universe 829 builds. As llvm 9.0 becomes vetted for these architectures, they 830 will be removed from the list. 831 83220191009: 833 Clang, llvm, lld, lldb, compiler-rt, libc++, libunwind and openmp have 834 been upgraded to 9.0.0. Please see the 20141231 entry below for 835 information about prerequisites and upgrading, if you are not already 836 using clang 3.5.0 or higher. 837 83820191003: 839 The hpt27xx, hptmv, hptnr, and hptrr drivers have been removed from 840 GENERIC. They are available as modules and can be loaded by adding 841 to /boot/loader.conf hpt27xx_load="YES", hptmv_load="YES", 842 hptnr_load="YES", or hptrr_load="YES", respectively. 843 84420190913: 845 ntpd no longer by default locks its pages in memory, allowing them 846 to be paged out by the kernel. Use rlimit memlock to restore 847 historic BSD behaviour. For example, add "rlimit memlock 32" 848 to ntp.conf to lock up to 32 MB of ntpd address space in memory. 849 85020190823: 851 Several of ping6's options have been renamed for better consistency 852 with ping. If you use any of -ARWXaghmrtwx, you must update your 853 scripts. See ping6(8) for details. 854 85520190727: 856 The vfs.fusefs.sync_unmount and vfs.fusefs.init_backgrounded sysctls 857 and the "-o sync_unmount" and "-o init_backgrounded" mount options have 858 been removed from mount_fusefs(8). You can safely remove them from 859 your scripts, because they had no effect. 860 861 The vfs.fusefs.fix_broken_io, vfs.fusefs.sync_resize, 862 vfs.fusefs.refresh_size, vfs.fusefs.mmap_enable, 863 vfs.fusefs.reclaim_revoked, and vfs.fusefs.data_cache_invalidate 864 sysctls have been removed. If you felt the need to set any of them to 865 a non-default value, please tell asomers@FreeBSD.org why. 866 86720190713: 868 Default permissions on the /var/account/acct file (and copies of it 869 rotated by periodic daily scripts) are changed from 0644 to 0640 870 because the file contains sensitive information that should not be 871 world-readable. If the /var/account directory must be created by 872 rc.d/accounting, the mode used is now 0750. Admins who use the 873 accounting feature are encouraged to change the mode of an existing 874 /var/account directory to 0750 or 0700. 875 87620190620: 877 Entropy collection and the /dev/random device are no longer optional 878 components. The "device random" option has been removed. 879 Implementations of distilling algorithms can still be made loadable 880 with "options RANDOM_LOADABLE" (e.g., random_fortuna.ko). 881 88220190612: 883 Clang, llvm, lld, lldb, compiler-rt, libc++, libunwind and openmp have 884 been upgraded to 8.0.1. Please see the 20141231 entry below for 885 information about prerequisites and upgrading, if you are not already 886 using clang 3.5.0 or higher. 887 88820190608: 889 A fix was applied to i386 kernel modules to avoid panics with 890 dpcpu or vnet. Users need to recompile i386 kernel modules 891 having pcpu or vnet sections or they will refuse to load. 892 89320190513: 894 User-wired pages now have their own counter, 895 vm.stats.vm.v_user_wire_count. The vm.max_wired sysctl was renamed 896 to vm.max_user_wired and changed from an unsigned int to an unsigned 897 long. bhyve VMs wired with the -S are now subject to the user 898 wiring limit; the vm.max_user_wired sysctl may need to be tuned to 899 avoid running into the limit. 900 90120190507: 902 The IPSEC option has been removed from GENERIC. Users requiring 903 ipsec(4) must now load the ipsec(4) kernel module. 904 90520190507: 906 The tap(4) driver has been folded into tun(4), and the module has been 907 renamed to tuntap. You should update any kld_list="if_tap" or 908 kld_list="if_tun" entries in /etc/rc.conf, if_tap_load="YES" or 909 if_tun_load="YES" entries in /boot/loader.conf to load the if_tuntap 910 module instead, and "device tap" or "device tun" entries in kernel 911 config files to select the tuntap device instead. 912 91320190418: 914 The following knobs have been added related to tradeoffs between 915 safe use of the random device and availability in the absence of 916 entropy: 917 918 kern.random.initial_seeding.bypass_before_seeding: tunable; set 919 non-zero to bypass the random device prior to seeding, or zero to 920 block random requests until the random device is initially seeded. 921 For now, set to 1 (unsafe) by default to restore pre-r346250 boot 922 availability properties. 923 924 kern.random.initial_seeding.read_random_bypassed_before_seeding: 925 read-only diagnostic sysctl that is set when bypass is enabled and 926 read_random(9) is bypassed, to enable programmatic handling of this 927 initial condition, if desired. 928 929 kern.random.initial_seeding.arc4random_bypassed_before_seeding: 930 Similar to the above, but for arc4random(9) initial seeding. 931 932 kern.random.initial_seeding.disable_bypass_warnings: tunable; set 933 non-zero to disable warnings in dmesg when the same conditions are 934 met as for the diagnostic sysctls above. Defaults to zero, i.e., 935 produce warnings in dmesg when the conditions are met. 936 93720190416: 938 The loadable random module KPI has changed; the random_infra_init() 939 routine now requires a 3rd function pointer for a bool (*)(void) 940 method that returns true if the random device is seeded (and 941 therefore unblocked). 942 94320190404: 944 r345895 reverts r320698. This implies that an nfsuserd(8) daemon 945 built from head sources between r320757 (July 6, 2017) and 946 r338192 (Aug. 22, 2018) will not work unless the "-use-udpsock" 947 is added to the command line. 948 nfsuserd daemons built from head sources that are post-r338192 are 949 not affected and should continue to work. 950 95120190320: 952 The fuse(4) module has been renamed to fusefs(4) for consistency with 953 other filesystems. You should update any kld_load="fuse" entries in 954 /etc/rc.conf, fuse_load="YES" entries in /boot/loader.conf, and 955 "options FUSE" entries in kernel config files. 956 95720190304: 958 Clang, llvm, lld, lldb, compiler-rt and libc++ have been upgraded to 959 8.0.0. Please see the 20141231 entry below for information about 960 prerequisites and upgrading, if you are not already using clang 3.5.0 961 or higher. 962 96320190226: 964 geom_uzip(4) depends on the new module xz. If geom_uzip is statically 965 compiled into your custom kernel, add 'device xz' statement to the 966 kernel config. 967 96820190219: 969 drm and drm2 have been removed from the tree. Please see 970 https://wiki.freebsd.org/Graphics for the latest information on 971 migrating to the drm ports. 972 97320190131: 974 Iflib is no longer unconditionally compiled into the kernel. Drivers 975 using iflib and statically compiled into the kernel, now require 976 the 'device iflib' config option. For the same drivers loaded as 977 modules on kernels not having 'device iflib', the iflib.ko module 978 is loaded automatically. 979 98020190125: 981 The IEEE80211_AMPDU_AGE and AH_SUPPORT_AR5416 kernel configuration 982 options no longer exist since r343219 and r343427 respectively; 983 nothing uses them, so they should be just removed from custom 984 kernel config files. 985 98620181230: 987 r342635 changes the way efibootmgr(8) works by requiring users to add 988 the -b (bootnum) parameter for commands where the bootnum was previously 989 specified with each option. For example 'efibootmgr -B 0001' is now 990 'efibootmgr -B -b 0001'. 991 99220181220: 993 r342286 modifies the NFSv4 server so that it obeys vfs.nfsd.nfs_privport 994 in the same as it is applied to NFSv2 and 3. This implies that NFSv4 995 servers that have vfs.nfsd.nfs_privport set will only allow mounts 996 from clients using a reserved port. Since both the FreeBSD and Linux 997 NFSv4 clients use reserved ports by default, this should not affect 998 most NFSv4 mounts. 999 100020181219: 1001 The XLP config has been removed. We can't support 64-bit atomics in this 1002 kernel because it is running in 32-bit mode. XLP users must transition 1003 to running a 64-bit kernel (XLP64 or XLPN32). 1004 1005 The mips GXEMUL support has been removed from FreeBSD. MALTA* + qemu is 1006 the preferred emulator today and we don't need two different ones. 1007 1008 The old sibyte / swarm / Broadcom BCM1250 support has been 1009 removed from the mips port. 1010 101120181211: 1012 Clang, llvm, lld, lldb, compiler-rt and libc++ have been upgraded to 1013 7.0.1. Please see the 20141231 entry below for information about 1014 prerequisites and upgrading, if you are not already using clang 3.5.0 1015 or higher. 1016 101720181211: 1018 Remove the timed and netdate programs from the base tree. Setting 1019 the time with these daemons has been obsolete for over a decade. 1020 102120181126: 1022 On amd64, arm64 and armv7 (architectures that install LLVM's ld.lld 1023 linker as /usr/bin/ld) GNU ld is no longer installed as ld.bfd, as 1024 it produces broken binaries when ifuncs are in use. Users needing 1025 GNU ld should install the binutils port or package. 1026 102720181123: 1028 The BSD crtbegin and crtend code has been enabled by default. It has 1029 had extensive testing on amd64, arm64, and i386. It can be disabled 1030 by building a world with -DWITHOUT_BSD_CRTBEGIN. 1031 103220181115: 1033 The set of CTM commands (ctm, ctm_smail, ctm_rmail, ctm_dequeue) 1034 has been converted to a port (misc/ctm) and will be removed from 1035 FreeBSD-13. It is available as a package (ctm) for all supported 1036 FreeBSD versions. 1037 103820181110: 1039 The default newsyslog.conf(5) file has been changed to only include 1040 files in /etc/newsyslog.conf.d/ and /usr/local/etc/newsyslog.conf.d/ if 1041 the filenames end in '.conf' and do not begin with a '.'. 1042 1043 You should check the configuration files in these two directories match 1044 this naming convention. You can verify which configuration files are 1045 being included using the command: 1046 $ newsyslog -Nrv 1047 104820181019: 1049 Stable/12 was branched created. 1050 105120181015: 1052 Ports for the DRM modules have been simplified. Now, amd64 users should 1053 just install the drm-kmod port. All others should install 1054 drm-legacy-kmod. 1055 1056 Graphics hardware that's newer than about 2010 usually works with 1057 drm-kmod. For hardware older than 2013, however, some users will need 1058 to use drm-legacy-kmod if drm-kmod doesn't work for them. Hardware older 1059 than 2008 usually only works in drm-legacy-kmod. The graphics team can 1060 only commit to hardware made since 2013 due to the complexity of the 1061 market and difficulty to test all the older cards effectively. If you 1062 have hardware supported by drm-kmod, you are strongly encouraged to use 1063 that as you will get better support. 1064 1065 Other than KPI chasing, drm-legacy-kmod will not be updated. As outlined 1066 elsewhere, the drm and drm2 modules will be eliminated from the src base 1067 soon (with a limited exception for arm). Please update to the package 1068 asap and report any issues to x11@freebsd.org. 1069 1070 Generally, anybody using the drm*-kmod packages should add 1071 WITHOUT_DRM_MODULE=t and WITHOUT_DRM2_MODULE=t to avoid nasty 1072 cross-threading surprises, especially with automatic driver 1073 loading from X11 startup. These will become the defaults in 13-current 1074 shortly. 1075 107620181012: 1077 The ixlv(4) driver has been renamed to iavf(4). As a consequence, 1078 custom kernel and module loading configuration files must be updated 1079 accordingly. Moreover, interfaces previous presented as ixlvN to the 1080 system are now exposed as iavfN and network configuration files must 1081 be adjusted as necessary. 1082 108320181009: 1084 OpenSSL has been updated to version 1.1.1. This update included 1085 additional various API changes throughout the base system. It is 1086 important to rebuild third-party software after upgrading. The value 1087 of __FreeBSD_version has been bumped accordingly. 1088 108920181006: 1090 The legacy DRM modules and drivers have now been added to the loader's 1091 module blacklist, in favor of loading them with kld_list in rc.conf(5). 1092 The module blacklist may be overridden with the loader.conf(5) 1093 'module_blacklist' variable, but loading them via rc.conf(5) is strongly 1094 encouraged. 1095 109620181002: 1097 The cam(4) based nda(4) driver will be used over nvd(4) by default on 1098 powerpc64. You may set 'options NVME_USE_NVD=1' in your kernel conf or 1099 loader tunable 'hw.nvme.use_nvd=1' if you wish to use the existing 1100 driver. Make sure to edit /boot/etc/kboot.conf and fstab to use the 1101 nda device name. 1102 110320180913: 1104 Reproducible build mode is now on by default, in preparation for 1105 FreeBSD 12.0. This eliminates build metadata such as the user, 1106 host, and time from the kernel (and uname), unless the working tree 1107 corresponds to a modified checkout from a version control system. 1108 The previous behavior can be obtained by setting the /etc/src.conf 1109 knob WITHOUT_REPRODUCIBLE_BUILD. 1110 111120180826: 1112 The Yarrow CSPRNG has been removed from the kernel as it has not been 1113 supported by its designers since at least 2003. Fortuna has been the 1114 default since FreeBSD-11. 1115 111620180822: 1117 devctl freeze/thaw have gone into the tree, the rc scripts have been 1118 updated to use them and devmatch has been changed. You should update 1119 kernel, userland and rc scripts all at the same time. 1120 112120180818: 1122 The default interpreter has been switched from 4th to Lua. 1123 LOADER_DEFAULT_INTERP, documented in build(7), will override the default 1124 interpreter. If you have custom FORTH code you will need to set 1125 LOADER_DEFAULT_INTERP=4th (valid values are 4th, lua or simp) in 1126 src.conf for the build. This will create default hard links between 1127 loader and loader_4th instead of loader and loader_lua, the new default. 1128 If you are using UEFI it will create the proper hard link to loader.efi. 1129 1130 bhyve uses userboot.so. It remains 4th-only until some issues are solved 1131 regarding coexisting with multiple versions of FreeBSD are resolved. 1132 113320180815: 1134 ls(1) now respects the COLORTERM environment variable used in other 1135 systems and software to indicate that a colored terminal is both 1136 supported and desired. If ls(1) is suddenly emitting colors, they may 1137 be disabled again by either removing the unwanted COLORTERM from your 1138 environment, or using `ls --color=never`. The ls(1) specific CLICOLOR 1139 may not be observed in a future release. 1140 114120180808: 1142 The default pager for most commands has been changed to "less". To 1143 restore the old behavior, set PAGER="more" and MANPAGER="more -s" in 1144 your environment. 1145 114620180731: 1147 The jedec_ts(4) driver has been removed. A superset of its functionality 1148 is available in the jedec_dimm(4) driver, and the manpage for that 1149 driver includes migration instructions. If you have "device jedec_ts" 1150 in your kernel configuration file, it must be removed. 1151 115220180730: 1153 amd64/GENERIC now has EFI runtime services, EFIRT, enabled by default. 1154 This should have no effect if the kernel is booted via BIOS/legacy boot. 1155 EFIRT may be disabled via a loader tunable, efi.rt.disabled, if a system 1156 has a buggy firmware that prevents a successful boot due to use of 1157 runtime services. 1158 115920180727: 1160 Atmel AT91RM9200 and AT91SAM9, Cavium CNS 11xx and XScale 1161 support has been removed from the tree. These ports were 1162 obsolete and/or known to be broken for many years. 1163 116420180723: 1165 loader.efi has been augmented to participate more fully in the 1166 UEFI boot manager protocol. loader.efi will now look at the 1167 BootXXXX environment variable to determine if a specific kernel 1168 or root partition was specified. XXXX is derived from BootCurrent. 1169 efibootmgr(8) manages these standard UEFI variables. 1170 117120180720: 1172 zfsloader's functionality has now been folded into loader. 1173 zfsloader is no longer necessary once you've updated your 1174 boot blocks. For a transition period, we will install a 1175 hardlink for zfsloader to loader to allow a smooth transition 1176 until the boot blocks can be updated (hard link because old 1177 zfs boot blocks don't understand symlinks). 1178 117920180719: 1180 ARM64 now have efifb support, if you want to have serial console 1181 on your arm64 board when an screen is connected and the bootloader 1182 setup a frame buffer for us to use, just add : 1183 boot_serial=YES 1184 boot_multicons=YES 1185 in /boot/loader.conf 1186 For Raspberry Pi 3 (RPI) users, this is needed even if you don't have 1187 an screen connected as the firmware will setup a frame buffer are that 1188 u-boot will expose as an EFI frame buffer. 1189 119020180719: 1191 New uid:gid added, ntpd:ntpd (123:123). Be sure to run mergemaster 1192 or take steps to update /etc/passwd before doing installworld on 1193 existing systems. Do not skip the "mergemaster -Fp" step before 1194 installworld, as described in the update procedures near the bottom 1195 of this document. Also, rc.d/ntpd now starts ntpd(8) as user ntpd 1196 if the new mac_ntpd(4) policy is available, unless ntpd_flags or 1197 the ntp config file contain options that change file/dir locations. 1198 When such options (e.g., "statsdir" or "crypto") are used, ntpd can 1199 still be run as non-root by setting ntpd_user=ntpd in rc.conf, after 1200 taking steps to ensure that all required files/dirs are accessible 1201 by the ntpd user. 1202 120320180717: 1204 Big endian arm support has been removed. 1205 120620180711: 1207 The static environment setup in kernel configs is no longer mutually 1208 exclusive with the loader(8) environment by default. In order to 1209 restore the previous default behavior of disabling the loader(8) 1210 environment if a static environment is present, you must specify 1211 loader_env.disabled=1 in the static environment. 1212 121320180705: 1214 The ABI of syscalls used by management tools like sockstat and 1215 netstat has been broken to allow 32-bit binaries to work on 1216 64-bit kernels without modification. These programs will need 1217 to match the kernel in order to function. External programs may 1218 require minor modifications to accommodate a change of type in 1219 structures from pointers to 64-bit virtual addresses. 1220 122120180702: 1222 On i386 and amd64 atomics are now inlined. Out of tree modules using 1223 atomics will need to be rebuilt. 1224 122520180701: 1226 The '%I' format in the kern.corefile sysctl limits the number of 1227 core files that a process can generate to the number stored in the 1228 debug.ncores sysctl. The '%I' format is replaced by the single digit 1229 index. Previously, if all indexes were taken the kernel would overwrite 1230 only a core file with the highest index in a filename. 1231 Currently the system will create a new core file if there is a free 1232 index or if all slots are taken it will overwrite the oldest one. 1233 123420180630: 1235 Clang, llvm, lld, lldb, compiler-rt and libc++ have been upgraded to 1236 6.0.1. Please see the 20141231 entry below for information about 1237 prerequisites and upgrading, if you are not already using clang 3.5.0 1238 or higher. 1239 124020180628: 1241 r335753 introduced a new quoting method. However, etc/devd/devmatch.conf 1242 needed to be changed to work with it. This change was made with r335763 1243 and requires a mergemaster / etcupdate / etc to update the installed 1244 file. 1245 124620180612: 1247 r334930 changed the interface between the NFS modules, so they all 1248 need to be rebuilt. r335018 did a __FreeBSD_version bump for this. 1249 125020180530: 1251 As of r334391 lld is the default amd64 system linker; it is installed 1252 as /usr/bin/ld. Kernel build workarounds (see 20180510 entry) are no 1253 longer necessary. 1254 125520180530: 1256 The kernel / userland interface for devinfo changed, so you'll 1257 need a new kernel and userland as a pair for it to work (rebuilding 1258 lib/libdevinfo is all that's required). devinfo and devmatch will 1259 not work, but everything else will when there's a mismatch. 1260 126120180523: 1262 The on-disk format for hwpmc callchain records has changed to include 1263 threadid corresponding to a given record. This changes the field offsets 1264 and thus requires that libpmcstat be rebuilt before using a kernel 1265 later than r334108. 1266 126720180517: 1268 The vxge(4) driver has been removed. This driver was introduced into 1269 HEAD one week before the Exar left the Ethernet market and is not 1270 known to be used. If you have device vxge in your kernel config file 1271 it must be removed. 1272 127320180510: 1274 The amd64 kernel now requires a ld that supports ifunc to produce a 1275 working kernel, either lld or a newer binutils. lld is built by default 1276 on amd64, and the 'buildkernel' target uses it automatically. However, 1277 it is not the default linker, so building the kernel the traditional 1278 way requires LD=ld.lld on the command line (or LD=/usr/local/bin/ld for 1279 binutils port/package). lld will soon be default, and this requirement 1280 will go away. 1281 1282 NOTE: As of r334391 lld is the default system linker on amd64, and no 1283 workaround is necessary. 1284 128520180508: 1286 The nxge(4) driver has been removed. This driver was for PCI-X 10g 1287 cards made by s2io/Neterion. The company was acquired by Exar and 1288 no longer sells or supports Ethernet products. If you have device 1289 nxge in your kernel config file it must be removed. 1290 129120180504: 1292 The tz database (tzdb) has been updated to 2018e. This version more 1293 correctly models time stamps in time zones with negative DST such as 1294 Europe/Dublin (from 1971 on), Europe/Prague (1946/7), and 1295 Africa/Windhoek (1994/2017). This does not affect the UT offsets, only 1296 time zone abbreviations and the tm_isdst flag. 1297 129820180502: 1299 The ixgb(4) driver has been removed. This driver was for an early and 1300 uncommon legacy PCI 10GbE for a single ASIC, Intel 82597EX. Intel 1301 quickly shifted to the long lived ixgbe family. If you have device 1302 ixgb in your kernel config file it must be removed. 1303 130420180501: 1305 The lmc(4) driver has been removed. This was a WAN interface 1306 card that was already reportedly rare in 2003, and had an ambiguous 1307 license. If you have device lmc in your kernel config file it must 1308 be removed. 1309 131020180413: 1311 Support for Arcnet networks has been removed. If you have device 1312 arcnet or device cm in your kernel config file they must be 1313 removed. 1314 131520180411: 1316 Support for FDDI networks has been removed. If you have device 1317 fddi or device fpa in your kernel config file they must be 1318 removed. 1319 132020180406: 1321 In addition to supporting RFC 3164 formatted messages, the 1322 syslogd(8) service is now capable of parsing RFC 5424 formatted 1323 log messages. The main benefit of using RFC 5424 is that clients 1324 may now send log messages with timestamps containing year numbers, 1325 microseconds and time zone offsets. 1326 1327 Similarly, the syslog(3) C library function has been altered to 1328 send RFC 5424 formatted messages to the local system logging 1329 daemon. On systems using syslogd(8), this change should have no 1330 negative impact, as long as syslogd(8) and the C library are 1331 updated at the same time. On systems using a different system 1332 logging daemon, it may be necessary to make configuration 1333 adjustments, depending on the software used. 1334 1335 When using syslog-ng, add the 'syslog-protocol' flag to local 1336 input sources to enable parsing of RFC 5424 formatted messages: 1337 1338 source src { 1339 unix-dgram("/var/run/log" flags(syslog-protocol)); 1340 } 1341 1342 When using rsyslog, disable the 'SysSock.UseSpecialParser' option 1343 of the 'imuxsock' module to let messages be processed by the 1344 regular RFC 3164/5424 parsing pipeline: 1345 1346 module(load="imuxsock" SysSock.UseSpecialParser="off") 1347 1348 Do note that these changes only affect communication between local 1349 applications and syslogd(8). The format that syslogd(8) uses to 1350 store messages on disk or forward messages to other systems 1351 remains unchanged. syslogd(8) still uses RFC 3164 for these 1352 purposes. Options to customize this behaviour will be added in the 1353 future. Utilities that process log files stored in /var/log are 1354 thus expected to continue to function as before. 1355 1356 __FreeBSD_version has been incremented to 1200061 to denote this 1357 change. 1358 135920180328: 1360 Support for token ring networks has been removed. If you 1361 have "device token" in your kernel config you should remove 1362 it. No device drivers supported token ring. 1363 136420180323: 1365 makefs was modified to be able to tag ISO9660 El Torito boot catalog 1366 entries as EFI instead of overloading the i386 tag as done previously. 1367 The amd64 mkisoimages.sh script used to build amd64 ISO images for 1368 release was updated to use this. This may mean that makefs must be 1369 updated before "make cdrom" can be run in the release directory. This 1370 should be as simple as: 1371 1372 $ cd $SRCDIR/usr.sbin/makefs 1373 $ make depend all install 1374 137520180212: 1376 FreeBSD boot loader enhanced with Lua scripting. It's purely opt-in for 1377 now by building WITH_LOADER_LUA and WITHOUT_FORTH in /etc/src.conf. 1378 Co-existence for the transition period will come shortly. Booting is a 1379 complex environment and test coverage for Lua-enabled loaders has been 1380 thin, so it would be prudent to assume it might not work and make 1381 provisions for backup boot methods. 1382 138320180211: 1384 devmatch functionality has been turned on in devd. It will automatically 1385 load drivers for unattached devices. This may cause unexpected drivers 1386 to be loaded. Please report any problems to current@ and 1387 imp@freebsd.org. 1388 138920180114: 1390 Clang, llvm, lld, lldb, compiler-rt and libc++ have been upgraded to 1391 6.0.0. Please see the 20141231 entry below for information about 1392 prerequisites and upgrading, if you are not already using clang 3.5.0 1393 or higher. 1394 139520180110: 1396 LLVM's lld linker is now used as the FreeBSD/amd64 bootstrap linker. 1397 This means it is used to link the kernel and userland libraries and 1398 executables, but is not yet installed as /usr/bin/ld by default. 1399 1400 To revert to ld.bfd as the bootstrap linker, in /etc/src.conf set 1401 WITHOUT_LLD_BOOTSTRAP=yes 1402 140320180110: 1404 On i386, pmtimer has been removed. Its functionality has been folded 1405 into apm. It was a no-op on ACPI in current for a while now (but was 1406 still needed on i386 in FreeBSD 11 and earlier). Users may need to 1407 remove it from kernel config files. 1408 140920180104: 1410 The use of RSS hash from the network card aka flowid has been 1411 disabled by default for lagg(4) as it's currently incompatible with 1412 the lacp and loadbalance protocols. 1413 1414 This can be re-enabled by setting the following in loader.conf: 1415 net.link.lagg.default_use_flowid="1" 1416 141720180102: 1418 The SW_WATCHDOG option is no longer necessary to enable the 1419 hardclock-based software watchdog if no hardware watchdog is 1420 configured. As before, SW_WATCHDOG will cause the software 1421 watchdog to be enabled even if a hardware watchdog is configured. 1422 142320171215: 1424 r326887 fixes the issue described in the 20171214 UPDATING entry. 1425 r326888 flips the switch back to building GELI support always. 1426 142720171214: 1428 r362593 broke ZFS + GELI support for reasons unknown. However, 1429 it also broke ZFS support generally, so GELI has been turned off 1430 by default as the lesser evil in r326857. If you boot off ZFS and/or 1431 GELI, it might not be a good time to update. 1432 143320171125: 1434 PowerPC users must update loader(8) by rebuilding world before 1435 installing a new kernel, as the protocol connecting them has 1436 changed. Without the update, loader metadata will not be passed 1437 successfully to the kernel and users will have to enter their 1438 root partition at the kernel mountroot prompt to continue booting. 1439 Newer versions of loader can boot old kernels without issue. 1440 144120171110: 1442 The LOADER_FIREWIRE_SUPPORT build variable has been renamed to 1443 WITH/OUT_LOADER_FIREWIRE. LOADER_{NO_,}GELI_SUPPORT has been renamed 1444 to WITH/OUT_LOADER_GELI. 1445 144620171106: 1447 The naive and non-compliant support of posix_fallocate(2) in ZFS 1448 has been removed as of r325320. The system call now returns EINVAL 1449 when used on a ZFS file. Although the new behavior complies with the 1450 standard, some consumers are not prepared to cope with it. 1451 One known victim is lld prior to r325420. 1452 145320171102: 1454 Building in a FreeBSD src checkout will automatically create object 1455 directories now rather than store files in the current directory if 1456 'make obj' was not ran. Calling 'make obj' is no longer necessary. 1457 This feature can be disabled by setting WITHOUT_AUTO_OBJ=yes in 1458 /etc/src-env.conf (not /etc/src.conf), or passing the option in the 1459 environment. 1460 146120171101: 1462 The default MAKEOBJDIR has changed from /usr/obj/<srcdir> for native 1463 builds, and /usr/obj/<arch>/<srcdir> for cross-builds, to a unified 1464 /usr/obj/<srcdir>/<arch>. This behavior can be changed to the old 1465 format by setting WITHOUT_UNIFIED_OBJDIR=yes in /etc/src-env.conf, 1466 the environment, or with -DWITHOUT_UNIFIED_OBJDIR when building. 1467 The UNIFIED_OBJDIR option is a transitional feature that will be 1468 removed for 12.0 release; please migrate to the new format for any 1469 tools by looking up the OBJDIR used by 'make -V .OBJDIR' means rather 1470 than hardcoding paths. 1471 147220171028: 1473 The native-xtools target no longer installs the files by default to the 1474 OBJDIR. Use the native-xtools-install target with a DESTDIR to install 1475 to ${DESTDIR}/${NXTP} where NXTP defaults to /nxb-bin. 1476 147720171021: 1478 As part of the boot loader infrastructure cleanup, LOADER_*_SUPPORT 1479 options are changing from controlling the build if defined / undefined 1480 to controlling the build with explicit 'yes' or 'no' values. They will 1481 shift to WITH/WITHOUT options to match other options in the system. 1482 148320171010: 1484 libstand has turned into a private library for sys/boot use only. 1485 It is no longer supported as a public interface outside of sys/boot. 1486 148720171005: 1488 The arm port has split armv6 into armv6 and armv7. armv7 is now 1489 a valid TARGET_ARCH/MACHINE_ARCH setting. If you have an armv7 system 1490 and are running a kernel from before r324363, you will need to add 1491 MACHINE_ARCH=armv7 to 'make buildworld' to do a native build. 1492 149320171003: 1494 When building multiple kernels using KERNCONF, non-existent KERNCONF 1495 files will produce an error and buildkernel will fail. Previously 1496 missing KERNCONF files silently failed giving no indication as to 1497 why, only to subsequently discover during installkernel that the 1498 desired kernel was never built in the first place. 1499 150020170912: 1501 The default serial number format for CTL LUNs has changed. This will 1502 affect users who use /dev/diskid/* device nodes, or whose FibreChannel 1503 or iSCSI clients care about their LUNs' serial numbers. Users who 1504 require serial number stability should hardcode serial numbers in 1505 /etc/ctl.conf . 1506 150720170912: 1508 For 32-bit arm compiled for hard-float support, soft-floating point 1509 binaries now always get their shared libraries from 1510 LD_SOFT_LIBRARY_PATH (in the past, this was only used if 1511 /usr/libsoft also existed). Only users with a hard-float ld.so, but 1512 soft-float everything else should be affected. 1513 151420170826: 1515 The geli password typed at boot is now hidden. To restore the previous 1516 behavior, see geli(8) for configuration options. 1517 151820170825: 1519 Move PMTUD blackhole counters to TCPSTATS and remove them from bare 1520 sysctl values. Minor nit, but requires a rebuild of both world/kernel 1521 to complete. 1522 152320170814: 1524 "make check" behavior (made in ^/head@r295380) has been changed to 1525 execute from a limited sandbox, as opposed to executing from 1526 ${TESTSDIR}. 1527 1528 Behavioral changes: 1529 - The "beforecheck" and "aftercheck" targets are now specified. 1530 - ${CHECKDIR} (added in commit noted above) has been removed. 1531 - Legacy behavior can be enabled by setting 1532 WITHOUT_MAKE_CHECK_USE_SANDBOX in src.conf(5) or the environment. 1533 1534 If the limited sandbox mode is enabled, "make check" will execute 1535 "make distribution", then install, execute the tests, and clean up the 1536 sandbox if successful. 1537 1538 The "make distribution" and "make install" targets are typically run as 1539 root to set appropriate permissions and ownership at installation time. 1540 The end-user should set "WITH_INSTALL_AS_USER" in src.conf(5) or the 1541 environment if executing "make check" with limited sandbox mode using 1542 an unprivileged user. 1543 154420170808: 1545 Since the switch to GPT disk labels, fsck for UFS/FFS has been 1546 unable to automatically find alternate superblocks. As of r322297, 1547 the information needed to find alternate superblocks has been 1548 moved to the end of the area reserved for the boot block. 1549 Filesystems created with a newfs of this vintage or later 1550 will create the recovery information. If you have a filesystem 1551 created prior to this change and wish to have a recovery block 1552 created for your filesystem, you can do so by running fsck in 1553 foreground mode (i.e., do not use the -p or -y options). As it 1554 starts, fsck will ask ``SAVE DATA TO FIND ALTERNATE SUPERBLOCKS'' 1555 to which you should answer yes. 1556 155720170728: 1558 As of r321665, an NFSv4 server configuration that services 1559 Kerberos mounts or clients that do not support the uid/gid in 1560 owner/owner_group string capability, must explicitly enable 1561 the nfsuserd daemon by adding nfsuserd_enable="YES" to the 1562 machine's /etc/rc.conf file. 1563 156420170722: 1565 Clang, llvm, lldb, compiler-rt and libc++ have been upgraded to 5.0.0. 1566 Please see the 20141231 entry below for information about prerequisites 1567 and upgrading, if you are not already using clang 3.5.0 or higher. 1568 156920170701: 1570 WITHOUT_RCMDS is now the default. Set WITH_RCMDS if you need the 1571 r-commands (rlogin, rsh, etc.) to be built with the base system. 1572 157320170625: 1574 The FreeBSD/powerpc platform now uses a 64-bit type for time_t. This is 1575 a very major ABI incompatible change, so users of FreeBSD/powerpc must 1576 be careful when performing source upgrades. It is best to run 1577 'make installworld' from an alternate root system, either a live 1578 CD/memory stick, or a temporary root partition. Additionally, all ports 1579 must be recompiled. powerpc64 is largely unaffected, except in the case 1580 of 32-bit compatibility. All 32-bit binaries will be affected. 1581 158220170623: 1583 Forward compatibility for the "ino64" project have been committed. This 1584 will allow most new binaries to run on older kernels in a limited 1585 fashion. This prevents many of the common foot-shooting actions in the 1586 upgrade as well as the limited ability to roll back the kernel across 1587 the ino64 upgrade. Complicated use cases may not work properly, though 1588 enough simpler ones work to allow recovery in most situations. 1589 159020170620: 1591 Switch back to the BSDL dtc (Device Tree Compiler). Set WITH_GPL_DTC 1592 if you require the GPL compiler. 1593 159420170619: 1595 Forward compatibility for the "ino64" project have been committed. This 1596 will allow most new binaries to run on older kernels in a limited 1597 fashion. This prevents many of the common foot-shooting actions in the 1598 upgrade as well as the limited ability to roll back the kernel across 1599 the ino64 upgrade. Complicated use cases may not work properly, though 1600 enough simpler ones work to allow recovery in most situations. 1601 160220170618: 1603 The internal ABI used for communication between the NFS kernel modules 1604 was changed by r320085, so __FreeBSD_version was bumped to 1605 ensure all the NFS related modules are updated together. 1606 160720170617: 1608 The ABI of struct event was changed by extending the data 1609 member to 64bit and adding ext fields. For upgrade, same 1610 precautions as for the entry 20170523 "ino64" must be 1611 followed. 1612 161320170531: 1614 The GNU roff toolchain has been removed from base. To render manpages 1615 which are not supported by mandoc(1), man(1) can fallback on GNU roff 1616 from ports (and recommends to install it). 1617 To render roff(7) documents, consider using GNU roff from ports or the 1618 heirloom doctools roff toolchain from ports via pkg install groff or 1619 via pkg install heirloom-doctools. 1620 162120170524: 1622 The ath(4) and ath_hal(4) modules now build piecemeal to allow for 1623 smaller runtime footprint builds. This is useful for embedded systems 1624 which only require one chipset support. 1625 1626 If you load it as a module, make sure this is in /boot/loader.conf: 1627 1628 if_ath_load="YES" 1629 1630 This will load the HAL, all chip/RF backends and if_ath_pci. 1631 If you have if_ath_pci in /boot/loader.conf, ensure it is after 1632 if_ath or it will not load any HAL chipset support. 1633 1634 If you want to selectively load things (eg on cheaper ARM/MIPS 1635 platforms where RAM is at a premium) you should: 1636 1637 * load ath_hal 1638 * load the chip modules in question 1639 * load ath_rate, ath_dfs 1640 * load ath_main 1641 * load if_ath_pci and/or if_ath_ahb depending upon your particular 1642 bus bind type - this is where probe/attach is done. 1643 1644 For further comments/feedback, poke adrian@ . 1645 164620170523: 1647 The "ino64" 64-bit inode project has been committed, which extends 1648 a number of types to 64 bits. Upgrading in place requires care and 1649 adherence to the documented upgrade procedure. 1650 1651 If using a custom kernel configuration ensure that the 1652 COMPAT_FREEBSD11 option is included (as during the upgrade the 1653 system will be running the ino64 kernel with the existing world). 1654 1655 For the safest in-place upgrade begin by removing previous build 1656 artifacts via "rm -rf /usr/obj/*". Then, carefully follow the full 1657 procedure documented below under the heading "To rebuild everything and 1658 install it on the current system." Specifically, a reboot is required 1659 after installing the new kernel before installing world. While an 1660 installworld normally works by accident from multiuser after rebooting 1661 the proper kernel, there are many cases where this will fail across this 1662 upgrade and installworld from single user is required. 1663 166420170424: 1665 The NATM framework including the en(4), fatm(4), hatm(4), and 1666 patm(4) devices has been removed. Consumers should plan a 1667 migration before the end-of-life date for FreeBSD 11. 1668 166920170420: 1670 GNU diff has been replaced by a BSD licensed diff. Some features of GNU 1671 diff has not been implemented, if those are needed a newer version of 1672 GNU diff is available via the diffutils package under the gdiff name. 1673 167420170413: 1675 As of r316810 for ipfilter, keep frags is no longer assumed when 1676 keep state is specified in a rule. r316810 aligns ipfilter with 1677 documentation in man pages separating keep frags from keep state. 1678 This allows keep state to be specified without forcing keep frags 1679 and allows keep frags to be specified independently of keep state. 1680 To maintain previous behaviour, also specify keep frags with 1681 keep state (as documented in ipf.conf.5). 1682 168320170407: 1684 arm64 builds now use the base system LLD 4.0.0 linker by default, 1685 instead of requiring that the aarch64-binutils port or package be 1686 installed. To continue using aarch64-binutils, set 1687 CROSS_BINUTILS_PREFIX=/usr/local/aarch64-freebsd/bin . 1688 168920170405: 1690 The UDP optimization in entry 20160818 that added the sysctl 1691 net.inet.udp.require_l2_bcast has been reverted. L2 broadcast 1692 packets will no longer be treated as L3 broadcast packets. 1693 169420170331: 1695 Binds and sends to the loopback addresses, IPv6 and IPv4, will now 1696 use any explicitly assigned loopback address available in the jail 1697 instead of using the first assigned address of the jail. 1698 169920170329: 1700 The ctl.ko module no longer implements the iSCSI target frontend: 1701 cfiscsi.ko does instead. 1702 1703 If building cfiscsi.ko as a kernel module, the module can be loaded 1704 via one of the following methods: 1705 - `cfiscsi_load="YES"` in loader.conf(5). 1706 - Add `cfiscsi` to `$kld_list` in rc.conf(5). 1707 - ctladm(8)/ctld(8), when compiled with iSCSI support 1708 (`WITH_ISCSI=yes` in src.conf(5)) 1709 1710 Please see cfiscsi(4) for more details. 1711 171220170316: 1713 The mmcsd.ko module now additionally depends on geom_flashmap.ko. 1714 Also, mmc.ko and mmcsd.ko need to be a matching pair built from the 1715 same source (previously, the dependency of mmcsd.ko on mmc.ko was 1716 missing, but mmcsd.ko now will refuse to load if it is incompatible 1717 with mmc.ko). 1718 171920170315: 1720 The syntax of ipfw(8) named states was changed to avoid ambiguity. 1721 If you have used named states in the firewall rules, you need to modify 1722 them after installworld and before rebooting. Now named states must 1723 be prefixed with colon. 1724 172520170311: 1726 The old drm (sys/dev/drm/) drivers for i915 and radeon have been 1727 removed as the userland we provide cannot use them. The KMS version 1728 (sys/dev/drm2) supports the same hardware. 1729 173020170302: 1731 Clang, llvm, lldb, compiler-rt and libc++ have been upgraded to 4.0.0. 1732 Please see the 20141231 entry below for information about prerequisites 1733 and upgrading, if you are not already using clang 3.5.0 or higher. 1734 173520170221: 1736 The code that provides support for ZFS .zfs/ directory functionality 1737 has been reimplemented. It's not possible now to create a snapshot 1738 by mkdir under .zfs/snapshot/. That should be the only user visible 1739 change. 1740 174120170216: 1742 EISA bus support has been removed. The WITH_EISA option is no longer 1743 valid. 1744 174520170215: 1746 MCA bus support has been removed. 1747 174820170127: 1749 The WITH_LLD_AS_LD / WITHOUT_LLD_AS_LD build knobs have been renamed 1750 WITH_LLD_IS_LD / WITHOUT_LLD_IS_LD, for consistency with CLANG_IS_CC. 1751 175220170112: 1753 The EM_MULTIQUEUE kernel configuration option is deprecated now that 1754 the em(4) driver conforms to iflib specifications. 1755 175620170109: 1757 The igb(4), em(4) and lem(4) ethernet drivers are now implemented via 1758 IFLIB. If you have a custom kernel configuration that excludes em(4) 1759 but you use igb(4), you need to re-add em(4) to your custom 1760 configuration. 1761 176220161217: 1763 Clang, llvm, lldb, compiler-rt and libc++ have been upgraded to 3.9.1. 1764 Please see the 20141231 entry below for information about prerequisites 1765 and upgrading, if you are not already using clang 3.5.0 or higher. 1766 176720161124: 1768 Clang, llvm, lldb, compiler-rt and libc++ have been upgraded to 3.9.0. 1769 Please see the 20141231 entry below for information about prerequisites 1770 and upgrading, if you are not already using clang 3.5.0 or higher. 1771 177220161119: 1773 The layout of the pmap structure has changed for powerpc to put the pmap 1774 statistics at the front for all CPU variations. libkvm(3) and all tools 1775 that link against it need to be recompiled. 1776 177720161030: 1778 isl(4) and cyapa(4) drivers now require a new driver, 1779 chromebook_platform(4), to work properly on Chromebook-class hardware. 1780 On other types of hardware the drivers may need to be configured using 1781 device hints. Please see the corresponding manual pages for details. 1782 178320161017: 1784 The urtwn(4) driver was merged into rtwn(4) and now consists of 1785 rtwn(4) main module + rtwn_usb(4) and rtwn_pci(4) bus-specific 1786 parts. 1787 Also, firmware for RTL8188CE was renamed due to possible name 1788 conflict (rtwnrtl8192cU(B) -> rtwnrtl8192cE(B)) 1789 179020161015: 1791 GNU rcs has been removed from base. It is available as packages: 1792 - rcs: Latest GPLv3 GNU rcs version. 1793 - rcs57: Copy of the latest version of GNU rcs (GPLv2) before it was 1794 removed from base. 1795 179620161008: 1797 Use of the cc_cdg, cc_chd, cc_hd, or cc_vegas congestion control 1798 modules now requires that the kernel configuration contain the 1799 TCP_HHOOK option. (This option is included in the GENERIC kernel.) 1800 180120161003: 1802 The WITHOUT_ELFCOPY_AS_OBJCOPY src.conf(5) knob has been retired. 1803 ELF Tool Chain's elfcopy is always installed as /usr/bin/objcopy. 1804 180520160924: 1806 Relocatable object files with the extension of .So have been renamed 1807 to use an extension of .pico instead. The purpose of this change is 1808 to avoid a name clash with shared libraries on case-insensitive file 1809 systems. On those file systems, foo.So is the same file as foo.so. 1810 181120160918: 1812 GNU rcs has been turned off by default. It can (temporarily) be built 1813 again by adding WITH_RCS knob in src.conf. 1814 Otherwise, GNU rcs is available from packages: 1815 - rcs: Latest GPLv3 GNU rcs version. 1816 - rcs57: Copy of the latest version of GNU rcs (GPLv2) from base. 1817 181820160918: 1819 The backup_uses_rcs functionality has been removed from rc.subr. 1820 182120160908: 1822 The queue(3) debugging macro, QUEUE_MACRO_DEBUG, has been split into 1823 two separate components, QUEUE_MACRO_DEBUG_TRACE and 1824 QUEUE_MACRO_DEBUG_TRASH. Define both for the original 1825 QUEUE_MACRO_DEBUG behavior. 1826 182720160824: 1828 r304787 changed some ioctl interfaces between the iSCSI userspace 1829 programs and the kernel. ctladm, ctld, iscsictl, and iscsid must be 1830 rebuilt to work with new kernels. __FreeBSD_version has been bumped 1831 to 1200005. 1832 183320160818: 1834 The UDP receive code has been updated to only treat incoming UDP 1835 packets that were addressed to an L2 broadcast address as L3 1836 broadcast packets. It is not expected that this will affect any 1837 standards-conforming UDP application. The new behaviour can be 1838 disabled by setting the sysctl net.inet.udp.require_l2_bcast to 1839 0. 1840 184120160818: 1842 Remove the openbsd_poll system call. 1843 __FreeBSD_version has been bumped because of this. 1844 184520160708: 1846 The stable/11 branch has been created from head@r302406. 1847 1848After branch N is created, entries older than the N-2 branch point are removed 1849from this file. After stable/14 is branched and current becomes FreeBSD 15, 1850entries older than stable/12 branch point will be removed from current's 1851UPDATING file. 1852 1853COMMON ITEMS: 1854 1855 General Notes 1856 ------------- 1857 Sometimes, obscure build problems are the result of environment 1858 poisoning. This can happen because the make utility reads its 1859 environment when searching for values for global variables. To run 1860 your build attempts in an "environmental clean room", prefix all make 1861 commands with 'env -i '. See the env(1) manual page for more details. 1862 Occasionally a build failure will occur with "make -j" due to a race 1863 condition. If this happens try building again without -j, and please 1864 report a bug if it happens consistently. 1865 1866 When upgrading from one major version to another it is generally best to 1867 upgrade to the latest code in the currently installed branch first, then 1868 do an upgrade to the new branch. This is the best-tested upgrade path, 1869 and has the highest probability of being successful. Please try this 1870 approach if you encounter problems with a major version upgrade. Since 1871 the stable 4.x branch point, one has generally been able to upgrade from 1872 anywhere in the most recent stable branch to head / current (or even the 1873 last couple of stable branches). See the top of this file when there's 1874 an exception. 1875 1876 The update process will emit an error on an attempt to perform a build 1877 or install from a FreeBSD version below the earliest supported version. 1878 When updating from an older version the update should be performed one 1879 major release at a time, including running `make delete-old` at each 1880 step. 1881 1882 When upgrading a live system, having a root shell around before 1883 installing anything can help undo problems. Not having a root shell 1884 around can lead to problems if pam has changed too much from your 1885 starting point to allow continued authentication after the upgrade. 1886 1887 This file should be read as a log of events. When a later event changes 1888 information of a prior event, the prior event should not be deleted. 1889 Instead, a pointer to the entry with the new information should be 1890 placed in the old entry. Readers of this file should also sanity check 1891 older entries before relying on them blindly. Authors of new entries 1892 should write them with this in mind. 1893 1894 ZFS notes 1895 --------- 1896 When upgrading the boot ZFS pool to a new version (via zpool upgrade), 1897 always follow these three steps: 1898 1899 1) recompile and reinstall the ZFS boot loader and boot block 1900 (this is part of "make buildworld" and "make installworld") 1901 1902 2) update the ZFS boot block on your boot drive (only required when 1903 doing a zpool upgrade): 1904 1905 When booting on x86 via BIOS, use the following to update the ZFS boot 1906 block on the freebsd-boot partition of a GPT partitioned drive ada0: 1907 gpart bootcode -p /boot/gptzfsboot -i $N ada0 1908 The value $N will typically be 1. For EFI booting, see EFI notes. 1909 1910 3) zpool upgrade the root pool. New bootblocks will work with old 1911 pools, but not vice versa, so they need to be updated before any 1912 zpool upgrade. 1913 1914 Non-boot pools do not need these updates. 1915 1916 EFI notes 1917 --------- 1918 1919 There are two locations the boot loader can be installed into. The 1920 current location (and the default) is \efi\freebsd\loader.efi and using 1921 efibootmgr(8) to configure it. The old location, that must be used on 1922 deficient systems that don't honor efibootmgr(8) protocols, is the 1923 fallback location of \EFI\BOOT\BOOTxxx.EFI. Generally, you will copy 1924 /boot/loader.efi to this location, but on systems installed a long time 1925 ago the ESP may be too small and /boot/boot1.efi may be needed unless 1926 the ESP has been expanded in the meantime. 1927 1928 Recent systems will have the ESP mounted on /boot/efi, but older ones 1929 may not have it mounted at all, or mounted in a different 1930 location. Older arm SD images with MBR used /boot/msdos as the 1931 mountpoint. The ESP is a MSDOS filesystem. 1932 1933 The EFI boot loader rarely needs to be updated. For ZFS booting, 1934 however, you must update loader.efi before you do 'zpool upgrade' the 1935 root zpool, otherwise the old loader.efi may reject the upgraded zpool 1936 since it does not automatically understand some new features. 1937 1938 See loader.efi(8) and uefi(8) for more details. 1939 1940 To build a kernel 1941 ----------------- 1942 If you are updating from a prior version of FreeBSD (even one just 1943 a few days old), you should follow this procedure. It is the most 1944 failsafe as it uses a /usr/obj tree with a fresh mini-buildworld, 1945 1946 make kernel-toolchain 1947 make -DALWAYS_CHECK_MAKE buildkernel KERNCONF=YOUR_KERNEL_HERE 1948 make -DALWAYS_CHECK_MAKE installkernel KERNCONF=YOUR_KERNEL_HERE 1949 1950 To test a kernel once 1951 --------------------- 1952 If you just want to boot a kernel once (because you are not sure 1953 if it works, or if you want to boot a known bad kernel to provide 1954 debugging information) run 1955 make installkernel KERNCONF=YOUR_KERNEL_HERE KODIR=/boot/testkernel 1956 nextboot -k testkernel 1957 1958 To rebuild everything and install it on the current system. 1959 ----------------------------------------------------------- 1960 # Note: sometimes if you are running current you gotta do more than 1961 # is listed here if you are upgrading from a really old current. 1962 1963 <make sure you have good level 0 dumps> 1964 make buildworld 1965 make buildkernel KERNCONF=YOUR_KERNEL_HERE 1966 make installkernel KERNCONF=YOUR_KERNEL_HERE 1967 [1] 1968 <reboot in single user> [3] 1969 etcupdate -p [5] 1970 make installworld 1971 etcupdate -B [4] 1972 make delete-old [6] 1973 <reboot> 1974 1975 To cross-install current onto a separate partition 1976 -------------------------------------------------- 1977 # In this approach we use a separate partition to hold 1978 # current's root, 'usr', and 'var' directories.

At this point in the life 2015 cycle of current, things change often and you are on your own 2016 to cope. The defaults can also change, so please read ALL of 2017 the UPDATING entries. 2018 2019 Also, if you are tracking -current, you must be subscribed to 2020 freebsd-current@freebsd.org. Make sure that before you update 2021 your sources that you have read and understood all the recent 2022 messages there. If in doubt, please track -stable which has 2023 much fewer pitfalls. 2024 2025 [1] If you have third party modules, such as vmware, you should disable 2026 them at this point so they don't crash your system on 2027 reboot. Alternatively, you should rebuild all the modules you have in 2028 your system and install them as well. If you are running -current, you 2029 should seriously consider placing all sources to all the modules for 2030 your system (or symlinks to them) in /usr/local/sys/modules so this 2031 happens automatically. If all your modules come from ports, then adding 2032 the port origin directories to PORTS_MODULES instead is also automatic 2033 and effective, eg: 2034 PORTS_MODULES+=x11/nvidia-driver 2035 2036 [3] From the bootblocks, boot -s, and then do 2037 fsck -p 2038 mount -u / 2039 mount -a 2040 sh /etc/rc.d/zfs start # mount zfs filesystem, if needed 2041 cd src # full path to source 2042 adjkerntz -i # if CMOS is wall time 2043 Also, when doing a major release upgrade, it is required that you boot 2044 into single user mode to do the installworld. 2045 2046 [4] Note: This step is non-optional. Failure to do this step 2047 can result in a significant reduction in the functionality of the 2048 system. Attempting to do it by hand is not recommended and those 2049 that pursue this avenue should read this file carefully, as well 2050 as the archives of freebsd-current and freebsd-hackers mailing lists 2051 for potential gotchas. See etcupdate(8) for more information. 2052 2053 [5] Usually this step is a no-op. However, from time to time 2054 you may need to do this if you get unknown user in the following 2055 step. 2056 2057 [6] This only deletes old files and directories. Old libraries 2058 can be deleted by "make delete-old-libs", but you have to make 2059 sure that no program is using those libraries anymore. 2060 2061 [8] The new kernel must be able to run existing binaries used by an 2062 installworld. When upgrading across major versions, the new kernel's 2063 configuration must include the correct COMPAT_FREEBSD<n> option for 2064 existing binaries (e.g. COMPAT_FREEBSD11 to run 11.x binaries). Failure 2065 to do so may leave you with a system that is hard to boot to recover. A 2066 GENERIC kernel will include suitable compatibility options to run 2067 binaries from older branches. Note that the ability to run binaries 2068 from unsupported branches is not guaranteed. 2069 2070 Make sure that you merge any new devices from GENERIC since the 2071 last time you updated your kernel config file. Options also 2072 change over time, so you may need to adjust your custom kernels 2073 for these as well. 2074 2075 [9] If CPUTYPE is defined in your /etc/make.conf, make sure to use the 2076 "?=" instead of the "=" assignment operator, so that buildworld can 2077 override the CPUTYPE if it needs to. 2078 2079 MAKEOBJDIRPREFIX must be defined in an environment variable, and 2080 not on the command line, or in /etc/make.conf. buildworld will 2081 warn if it is improperly defined. 2082FORMAT: 2083 2084This file contains a list, in reverse chronological order, of major 2085breakages in tracking -current. It is not guaranteed to be a complete 2086list of such breakages, and only contains entries since September 23, 2011. 2087If you need to see UPDATING entries from before that date, you will need 2088to fetch an UPDATING file from an older FreeBSD release. 2089 2090Copyright information: 2091 2092Copyright 1998-2009 M.
