1Updating Information for FreeBSD current users. 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 14.x IS SLOW: 16 FreeBSD 14.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 3020211230: 31 The macros provided for the manipulation of CPU sets (e.g. CPU_AND) 32 have been modified to take 2 source arguments instead of only 1. 33 Externally maintained sources that use these macros will have to 34 be adapted. The FreeBSD version has been bumped to 1400046 to 35 reflect this change. 36 3720211214: 38 A number of the kernel include files are able to be included by 39 themselves. A test has been added to buildworld to enforce this. 40 4120211209: 42 Remove mips as a recognized target. This starts the decommissioning of 43 mips support in FreeBSD. mips related items will be removed wholesale in 44 the coming days and weeks. 45 46 This broke the NO_CLEAN build for some people. Either do a clean build 47 or touch 48 lib/clang/include/llvm/Config/Targets.def 49 lib/clang/include/llvm/Config/AsmParsers.def 50 lib/clang/include/llvm/Config/Disassemblers.def 51 lib/clang/include/llvm/Config/AsmPrinters.def 52 before the build to force everything to rebuild that needs to. 53 5420211202: 55 Unbound support for RFC8375: The special-use domain 'home.arpa' is 56 by default blocked. To unblock it use a local-zone nodefault 57 statement in unbound.conf: 58 local-zone: "home.arpa." nodefault 59 60 Or use another type of local-zone to override with your choice. 61 62 The reason for this is discussed in Section 6.1 of RFC8375: 63 Because 'home.arpa.' is not globally scoped and cannot be secured 64 using DNSSEC based on the root domain's trust anchor, there is no way 65 to tell, using a standard DNS query, in which homenet scope an answer 66 belongs. Consequently, users may experience surprising results with 67 such names when roaming to different homenets. 68 6920211110: 70 Commit b8d60729deef changed the TCP congestion control framework so 71 that any of the included congestion control modules could be 72 the single module built into the kernel. Previously newreno 73 was automatically built in through direct reference. As of 74 this commit you are required to declare at least one congestion 75 control module (e.g. 'options CC_NEWRENO') and to also declare a 76 default using the CC_DEFAULT option (e.g. options CC_DEFAULT="newreno\"). 77 The GENERIC configuation includes CC_NEWRENO and defines newreno 78 as the default. If no congestion control option is built into the 79 kernel and you are including networking, the kernel compile will 80 fail. Also if no default is declared the kernel compile will fail. 81 8220211118: 83 Mips has been removed from universe builds. It will be removed from the 84 tree shortly. 85 8620211106: 87 Commit f0c9847a6c47 changed the arguments for VOP_ALLOCATE. 88 The NFS modules must be rebuilt from sources and any out 89 of tree file systems that implement their own VOP_ALLOCATE 90 may need to be modified. 91 9220211022: 93 The synchronous PPP kernel driver sppp(4) has been removed. 94 The cp(4) and ce(4) drivers are now always compiled with netgraph(4) 95 support, formerly enabled by NETGRAPH_CRONYX option. 96 9720211020: 98 sh(1) is now the default shell for the root user. To force root to use 99 the csh shell, please run the following command as root: 100 101 # chsh -s csh 102 10320211004: 104 Ncurses distribution has been split between libtinfow and libncurses 105 with libncurses.so becoming a linker (ld) script to seamlessly link 106 to libtinfow as needed. Bump _FreeBSD_version to 1400035 to reflect 107 this change. 108 10920210923: 110 As of commit 8160a0f62be6, the dummynet module no longer depends on the 111 ipfw module. Dummynet can now be used by pf as well as ipfw. As such 112 users who relied on this dependency may need to include ipfw in the 113 list of modules to load on their systems. 114 11520210922: 116 As of commit 903873ce1560, the mixer(8) utility has got a slightly 117 new syntax. Please refer to the mixer(8) manual page for more 118 information. The old mixer utility can be installed from ports: 119 audio/freebsd-13-mixer 120 12120210911: 122 As of commit 55089ef4f8bb, the global variable nfs_maxcopyrange has 123 been deleted from the nfscommon.ko. As such, nfsd.ko must be built 124 from up to date sources to avoid an undefined reference when 125 being loaded. 126 12720210817: 128 As of commit 62ca9fc1ad56 OpenSSL no longer enables kernel TLS 129 by default. Users can enable kernel TLS via the "KTLS" SSL 130 option. This can be enabled globally by using a custom 131 OpenSSL config file via OPENSSL_CONF or via an 132 application-specific configuration option for applications 133 which permit setting SSL options via SSL_CONF_cmd(3). 134 13520210811: 136 Commit 3ad1e1c1ce20 changed the internal KAPI between the NFS 137 modules. Therefore, all need to be rebuilt from sources. 138 13920210730: 140 Commit b69019c14cd8 removes pf's DIOCGETSTATESNV ioctl. 141 As of be70c7a50d32 it is no longer used by userspace, but it does mean 142 users may not be able to enumerate pf states if they update the kernel 143 past b69019c14cd8 without first updating userspace past be70c7a50d32. 144 14520210729: 146 As of commit 01ad0c007964 if_bridge member interfaces can no longer 147 change their MTU. Changing the MTU of the bridge itself will change the 148 MTU on all member interfaces instead. 149 15020210716: 151 Commit ee29e6f31111 changed the internal KAPI between the nfscommon 152 and nfsd modules. Therefore, both need to be rebuilt from sources. 153 Bump __FreeBSD_version to 1400026 for this KAPI change. 154 15520210715: 156 The 20210707 awk update brought in a change in behavior. This has 157 been corrected as of d4d252c49976. Between these dates, if you 158 installed a new awk binary, you may not be able to build a new 159 kernel because the change in behavior affected the genoffset 160 script used to build the kernel. If you did update, the fix is 161 to update your sources past the above hash and do 162 % cd usr.bin/awk 163 % make clean all 164 % sudo -E make install 165 to enable building kernels again. 166 16720210708: 168 Commit 1e0a518d6548 changed the internal KAPI between the NFS 169 modules. They all need to be rebuilt from sources. I did not 170 bump __FreeBSD_version, since it was bumped recently. 171 17220210707: 173 awk has been updated to the latest one-true-awk version 20210215. 174 This contains a number of minor bug fixes. 175 17620210624: 177 The NFSv4 client now uses the highest minor version of NFSv4 178 supported by the NFSv4 server by default instead of minor version 0, 179 for NFSv4 mounts. 180 The "minorversion" mount option may be used to override this default. 181 18220210618: 183 Bump __FreeBSD_version to 1400024 for LinuxKPI changes. 184 Most notably netdev.h can change now as the (last) dependencies 185 (mlx4/ofed) are now using struct ifnet directly, but also for PCI 186 additions and others. 187 18820210618: 189 The directory "blacklisted" under /usr/share/certs/ has been 190 renamed to "untrusted". 191 19220210611: 193 svnlite has been removed from base. Should you need svn for any reason 194 please install the svn package or port. 195 19620210611: 197 Commit e1a907a25cfa changed the internal KAPI between the krpc 198 and nfsserver. As such, both modules must be rebuilt from 199 sources. Bump __FreeBSD_version to 1400022. 200 20120210610: 202 The an(4) driver has been removed from FreeBSD. 203 20420210608: 205 The vendor/openzfs branch was renamed to vendor/openzfs/legacy to 206 start tracking OpenZFS upstream more closely. Please see 207https://lists.freebsd.org/archives/freebsd-current/2021-June/000153.html 208 for details on how to correct any errors that might result. The 209 short version is that you need to remove the old branch locally: 210 git update-ref -d refs/remotes/freebsd/vendor/openzfs 211 (assuming your upstream origin is named 'freebsd'). 212 21320210525: 214 Commits 17accc08ae15 and de102f870501 add new files to LinuxKPI 215 which break drm-kmod. In addition various other additions where 216 comitted. Bump __FreeBSD_version to 1400015 to be able to detect this. 217 21820210513: 219 Commit ca179c4d74f2 changed the package in which the OpenSSL 220 libraries and utilities are packaged. 221 It is recommended for pkgbase user to do: 222 pkg install -f FreeBSD-openssl 223 before pkg upgrade otherwise some dependencies might not be met 224 and pkg will stop working as libssl will not be present anymore 225 on the system. 226 22720210426: 228 Commit 875977314881 changed the internal KAPI between 229 the nfsd and nfscommon modules. As such these modules 230 need to be rebuilt from sources. 231 Without this patch in your NFSv4.1/4.2 server, enabling 232 delegations by setting vfs.nfsd.issue_delegations non-zero 233 is not recommended. 234 23520210411: 236 Commit 7763814fc9c2 changed the internal KAPI between 237 the krpc and NFS. As such, the krpc, nfscommon and 238 nfscl modules must all be rebuilt from sources. 239 Without this patch, NFSv4.1/4.2 mounts should not 240 be done with the nfscbd(8) daemon running, to avoid 241 needing a working back channel for server->client RPCs. 242 24320210330: 244 Commit 01ae8969a9ee fixed the NFSv4.1/4.2 server so that it 245 handles binding of the back channel as required by RFC5661. 246 Until this patch is in your server, avoid use of the "nconnects" 247 mount option for Linux NFSv4.1/4.2 mounts. 248 24920210225: 250 For 64-bit architectures the base system is now built with Position 251 Independent Executable (PIE) support enabled by default. It may be 252 disabled using the WITHOUT_PIE knob. A clean build is required. 253 25420210128: 255 Various LinuxKPI functionality was added which conflicts with DRM. 256 Please update your drm-kmod port to after the __FreeBSD_verison 1400003 257 update. 258 25920210108: 260 PC Card attachments for all devices have been removed. In the case of 261 wi and cmx, the entire drivers were removed because they were only 262 PC Card devices. FreeBSD_version 1300134 should be used for this 263 since it was bumped so recently. 264 26520210107: 266 Transport-independent parts of HID support have been split off the USB 267 code in to separate subsystem. Kernel configs which include one of 268 ums, ukbd, uhid, atp, wsp, wmt, uaudio, ugold or ucycom drivers should 269 be updated with adding of "device hid" line. 270 27120210105: 272 ncurses installation has been modified to only keep the widechar 273 enabled version. Incremental build is broken for that change, so it 274 requires a clean build. 275 27620201223: 277 The FreeBSD project has migrated from Subversion to Git. Temporary 278 instructions can be found at 279 https://github.com/bsdimp/freebsd-git-docs/blob/main/src-cvt.md 280 and other documents in that repo. 281 28220201216: 283 The services database has been updated to cover more of the basic 284 services expected in a modern system. The database is big enough 285 that it will cause issues in mergemaster in Releases previous to 286 12.2 and 11.3, or in very old current systems from before r358154. 287 28820201215: 289 Obsolete in-tree GDB 6.1.1 has been removed. GDB (including kgdb) 290 may be installed from ports or packages. 291 29220201124: 293 ping6 has been merged into ping. It can now be called as "ping -6". 294 See ping(8) for details. 295 29620201108: 297 Default value of net.add_addr_allfibs has been changed to 0. 298 If you have multi-fib configuration and rely on existence of all 299 interface routes in every fib, you need to set the above sysctl to 1. 300 30120201030: 302 The internal pre-processor in the calendar(1) program has been 303 extended to support more C pre-processor commands (e.g. #ifdef, #else, 304 and #undef) and to detect unbalanced conditional statements. 305 Error messages have been extended to include the filename and line 306 number if processing stops to help fixing malformed data files. 307 30820201026: 309 All the data files for the calendar(1) program, except calendar.freebsd, 310 have been moved to the deskutils/calendar-data port, much like the 311 jewish calendar entries were moved to deskutils/hebcal years ago. After 312 make delete-old-files, you need to install it to retain full 313 functionality. calendar(1) will issue a reminder for files it can't 314 find. 315 31620200923: 317 LINT files are no longer generated. We now include the relevant NOTES 318 files. Note: This may cause conflicts with updating in some cases. 319 find sys -name LINT\* -delete 320 is suggested across this commit to remove the generated LINT files. 321 322 If you have tried to update with generated files there, the svn 323 command you want to un-auger the tree is 324 cd sys/amd64/conf 325 svn revert -R . 326 and then do the above find from the top level. Substitute 'amd64' 327 above with where the error message indicates a conflict. 328 32920200824: 330 OpenZFS support has been integrated. Do not upgrade root pools until 331 the loader is updated to support zstd. Furthermore, we caution against 332 'zpool upgrade' for the next few weeks. The change should be transparent 333 unless you want to use new features. 334 335 Not all "NO_CLEAN" build scenarios work across these changes. Many 336 scenarios have been tested and fixed, but rebuilding kernels without 337 rebuilding world may fail. 338 339 The ZFS cache file has moved from /boot to /etc to match the OpenZFS 340 upstream default. A fallback to /boot has been added for mountroot. 341 342 Pool auto import behavior at boot has been moved from the kernel module 343 to an explicit "zpool import -a" in one of the rc scripts enabled by 344 zfs_enable=YES. This means your non-root zpools won't auto import until 345 you upgrade your /etc/rc.d files. 346 34720200824: 348 The resume code now notifies devd with the 'kernel' system 349 rather than the old 'kern' subsystem to be consistent with 350 other use. The old notification will be created as well, but 351 will be removed prior to FreeBSD 14.0. 352 35320200821: 354 r362275 changed the internal API between the kernel RPC and the 355 NFS modules. As such, all the modules must be recompiled from 356 sources. 357 35820200817: 359 r364330 modified the internal API used between the NFS modules. 360 As such, all the NFS modules must be re-compiled from sources. 361 36220200816: 363 Clang, llvm, lld, lldb, compiler-rt, libc++, libunwind and openmp have 364 been upgraded to 11.0.0. Please see the 20141231 entry below for 365 information about prerequisites and upgrading, if you are not already 366 using clang 3.5.0 or higher. 367 36820200810: 369 r364092 modified the internal ABI used between the kernel NFS 370 modules. As such, all of these modules need to be rebuilt 371 from sources, so a version bump was done. 372 37320200807: 374 Makefile.inc has been updated to work around the issue documented in 375 20200729. It was a case where the optimization of using symbolic links 376 to point to binaries created a situation where we'd run new binaries 377 with old libraries starting midway through the installworld process. 378 37920200729: 380 r363679 has redefined some undefined behavior in regcomp(3); notably, 381 extraneous escapes of most ordinary characters will no longer be 382 accepted. An exp-run has identified all of the problems with this in 383 ports, but other non-ports software may need extra escapes removed to 384 continue to function. 385 386 Because of this change, installworld may encounter the following error 387 from rtld: Undefined symbol "regcomp@FBSD_1.6" -- It is imperative that 388 you do not halt installworld. Instead, let it run to completion (whether 389 successful or not) and run installworld once more. 390 39120200627: 392 A new implementation of bc and dc has been imported in r362681. This 393 implementation corrects non-conformant behavior of the previous bc 394 and adds GNU bc compatible options. It offers a number of extensions, 395 is much faster on large values, and has support for message catalogs 396 (a number of languages are already supported, contributions of further 397 languages welcome). The option WITHOUT_GH_BC can be used to build the 398 world with the previous versions of bc and dc. 399 40020200625: 401 r362639 changed the internal API used between the NFS kernel modules. 402 As such, they all need to be rebuilt from sources. 403 40420200613: 405 r362158 changed the arguments for VFS_CHECKEXP(). As such, any 406 out of tree file systems need to be modified and rebuilt. 407 Also, any file systems that are modules must be rebuilt. 408 40920200604: 410 read(2) of a directory fd is now rejected by default. root may 411 re-enable it for system root only on non-ZFS filesystems with the 412 security.bsd.allow_read_dir sysctl(8) MIB if 413 security.bsd.suser_enabled=1. 414 415 It may be advised to setup aliases for grep to default to `-d skip` if 416 commonly non-recursively grepping a list that includes directories and 417 the potential for the resulting stderr output is not tolerable. Example 418 aliases are now installed, commented out, in /root/.cshrc and 419 /root/.shrc. 420 42120200523: 422 Clang, llvm, lld, lldb, compiler-rt, libc++, libunwind and openmp have 423 been upgraded to 10.0.1. Please see the 20141231 entry below for 424 information about prerequisites and upgrading, if you are not already 425 using clang 3.5.0 or higher. 426 42720200512: 428 Support for obsolete compilers has been removed from the build system. 429 Clang 6 and GCC 6.4 are the minimum supported versions. 430 43120200424: 432 closefrom(2) has been moved under COMPAT12, and replaced in libc with a 433 stub that calls close_range(2). If using a custom kernel configuration, 434 you may want to ensure that the COMPAT_FREEBSD12 option is included, as 435 a slightly older -CURRENT userland and older FreeBSD userlands may not 436 be functional without closefrom(2). 437 43820200414: 439 Upstream DTS from Linux 5.6 was merged and they now have the SID 440 and THS (Secure ID controller and THermal Sensor) node present. 441 The DTB overlays have now been removed from the tree for the H3/H5 and 442 A64 SoCs and the aw_sid and aw_thermal driver have been updated to 443 deal with upstream DTS. If you are using those overlays you need to 444 remove them from loader.conf and update the DTBs on the FAT partition. 445 44620200310: 447 Clang, llvm, lld, lldb, compiler-rt, libc++, libunwind and openmp have 448 been upgraded to 10.0.0. Please see the 20141231 entry below for 449 information about prerequisites and upgrading, if you are not already 450 using clang 3.5.0 or higher. 451 45220200309: 453 The amd(8) automount daemon has been removed from the source tree. 454 As of FreeBSD 10.1 autofs(5) is the preferred tool for automounting. 455 amd is still available in the sysutils/am-utils port. 456 45720200301: 458 Removed brooktree driver (bktr.4) from the tree. 459 46020200229: 461 The WITH_GPL_DTC option has been removed. The BSD-licenced device tree 462 compiler in usr.bin/dtc is used on all architectures which use dtc, and 463 the GPL dtc is available (if needed) from the sysutils/dtc port. 464 46520200229: 466 The WITHOUT_LLVM_LIBUNWIND option has been removed. LLVM's libunwind 467 is used by all supported CPU architectures. 468 46920200229: 470 GCC 4.2.1 has been removed from the tree. The WITH_GCC, 471 WITH_GCC_BOOTSTRAP, and WITH_GNUCXX options are no longer available. 472 Users who wish to build FreeBSD with GCC must use the external toolchain 473 ports or packages. 474 47520200220: 476 ncurses has been updated to a newer version (6.2-20200215). Given the ABI 477 has changed, users will have to rebuild all the ports that are linked to 478 ncurses. 479 48020200217: 481 The size of struct vnet and the magic cookie have changed. 482 Users need to recompile libkvm and all modules using VIMAGE 483 together with their new kernel. 484 48520200212: 486 Defining the long deprecated NO_CTF, NO_DEBUG_FILES, NO_INSTALLLIB, 487 NO_MAN, NO_PROFILE, and NO_WARNS variables is now an error. Update 488 your Makefiles and scripts to define MK_<var>=no instead as required. 489 490 One exception to this is that program or library Makefiles should 491 define MAN to empty rather than setting MK_MAN=no. 492 49320200108: 494 Clang/LLVM is now the default compiler and LLD the default 495 linker for riscv64. 496 49720200107: 498 make universe no longer uses GCC 4.2.1 on any architectures. 499 Architectures not supported by in-tree Clang/LLVM require an 500 external toolchain package. 501 50220200104: 503 GCC 4.2.1 is now not built by default, as part of the GCC 4.2.1 504 retirement plan. Specifically, the GCC, GCC_BOOTSTRAP, and GNUCXX 505 options default to off for all supported CPU architectures. As a 506 short-term transition aid they may be enabled via WITH_* options. 507 GCC 4.2.1 is expected to be removed from the tree on 2020-03-31. 508 50920200102: 510 Support for armv5 has been disconnected and is being removed. The 511 machine combination MACHINE=arm MACHINE_ARCH=arm is no longer valid. 512 You must now use a MACHINE_ARCH of armv6 or armv7. The default 513 MACHINE_ARCH for MACHINE=arm is now armv7. 514 51520191226: 516 Clang/LLVM is now the default compiler for all powerpc architectures. 517 LLD is now the default linker for powerpc64. The change for powerpc64 518 also includes a change to the ELFv2 ABI, incompatible with the existing 519 ABI. 520 52120191226: 522 Kernel-loadable random(4) modules are no longer unloadable. 523 52420191222: 525 Clang, llvm, lld, lldb, compiler-rt, libc++, libunwind and openmp have 526 been upgraded to 9.0.1. Please see the 20141231 entry below for 527 information about prerequisites and upgrading, if you are not already 528 using clang 3.5.0 or higher. 529 53020191212: 531 r355677 has modified the internal interface used between the 532 NFS modules in the kernel. As such, they must all be upgraded 533 simultaneously. I will do a version bump for this. 534 53520191205: 536 The root certificates of the Mozilla CA Certificate Store have been 537 imported into the base system and can be managed with the certctl(8) 538 utility. If you have installed the security/ca_root_nss port or package 539 with the ETCSYMLINK option (the default), be advised that there may be 540 differences between those included in the port and those included in 541 base due to differences in nss branch used as well as general update 542 frequency. Note also that certctl(8) cannot manage certs in the 543 format used by the security/ca_root_nss port. 544 54520191120: 546 The amd(8) automount daemon has been disabled by default, and will be 547 removed in the future. As of FreeBSD 10.1 the autofs(5) is available 548 for automounting. 549 55020191107: 551 The nctgpio and wbwd drivers have been moved to the superio bus. 552 If you have one of these drivers in a kernel configuration, then 553 you should add device superio to it. If you use one of these drivers 554 as a module and you compile a custom set of modules, then you should 555 add superio to the set. 556 55720191021: 558 KPIs for network drivers to access interface addresses have changed. 559 Users need to recompile NIC driver modules together with kernel. 560 56120191021: 562 The net.link.tap.user_open sysctl no longer prevents user opening of 563 already created /dev/tapNN devices. Access is still controlled by 564 node permissions, just like tun devices. The net.link.tap.user_open 565 sysctl is now used only to allow users to perform devfs cloning of 566 tap devices, and the subsequent open may not succeed if the user is not 567 in the appropriate group. This sysctl may be deprecated/removed 568 completely in the future. 569 57020191009: 571 mips, powerpc, and sparc64 are no longer built as part of 572 universe / tinderbox unless MAKE_OBSOLETE_GCC is defined. If 573 not defined, mips, powerpc, and sparc64 builds will look for 574 the xtoolchain binaries and if installed use them for universe 575 builds. As llvm 9.0 becomes vetted for these architectures, they 576 will be removed from the list. 577 57820191009: 579 Clang, llvm, lld, lldb, compiler-rt, libc++, libunwind and openmp have 580 been upgraded to 9.0.0. Please see the 20141231 entry below for 581 information about prerequisites and upgrading, if you are not already 582 using clang 3.5.0 or higher. 583 58420191003: 585 The hpt27xx, hptmv, hptnr, and hptrr drivers have been removed from 586 GENERIC. They are available as modules and can be loaded by adding 587 to /boot/loader.conf hpt27xx_load="YES", hptmv_load="YES", 588 hptnr_load="YES", or hptrr_load="YES", respectively. 589 59020190913: 591 ntpd no longer by default locks its pages in memory, allowing them 592 to be paged out by the kernel. Use rlimit memlock to restore 593 historic BSD behaviour. For example, add "rlimit memlock 32" 594 to ntp.conf to lock up to 32 MB of ntpd address space in memory. 595 59620190823: 597 Several of ping6's options have been renamed for better consistency 598 with ping. If you use any of -ARWXaghmrtwx, you must update your 599 scripts. See ping6(8) for details. 600 60120190727: 602 The vfs.fusefs.sync_unmount and vfs.fusefs.init_backgrounded sysctls 603 and the "-o sync_unmount" and "-o init_backgrounded" mount options have 604 been removed from mount_fusefs(8). You can safely remove them from 605 your scripts, because they had no effect. 606 607 The vfs.fusefs.fix_broken_io, vfs.fusefs.sync_resize, 608 vfs.fusefs.refresh_size, vfs.fusefs.mmap_enable, 609 vfs.fusefs.reclaim_revoked, and vfs.fusefs.data_cache_invalidate 610 sysctls have been removed. If you felt the need to set any of them to 611 a non-default value, please tell asomers@FreeBSD.org why. 612 61320190713: 614 Default permissions on the /var/account/acct file (and copies of it 615 rotated by periodic daily scripts) are changed from 0644 to 0640 616 because the file contains sensitive information that should not be 617 world-readable. If the /var/account directory must be created by 618 rc.d/accounting, the mode used is now 0750. Admins who use the 619 accounting feature are encouraged to change the mode of an existing 620 /var/account directory to 0750 or 0700. 621 62220190620: 623 Entropy collection and the /dev/random device are no longer optional 624 components. The "device random" option has been removed. 625 Implementations of distilling algorithms can still be made loadable 626 with "options RANDOM_LOADABLE" (e.g., random_fortuna.ko). 627 62820190612: 629 Clang, llvm, lld, lldb, compiler-rt, libc++, libunwind and openmp have 630 been upgraded to 8.0.1. Please see the 20141231 entry below for 631 information about prerequisites and upgrading, if you are not already 632 using clang 3.5.0 or higher. 633 63420190608: 635 A fix was applied to i386 kernel modules to avoid panics with 636 dpcpu or vnet. Users need to recompile i386 kernel modules 637 having pcpu or vnet sections or they will refuse to load. 638 63920190513: 640 User-wired pages now have their own counter, 641 vm.stats.vm.v_user_wire_count. The vm.max_wired sysctl was renamed 642 to vm.max_user_wired and changed from an unsigned int to an unsigned 643 long. bhyve VMs wired with the -S are now subject to the user 644 wiring limit; the vm.max_user_wired sysctl may need to be tuned to 645 avoid running into the limit. 646 64720190507: 648 The IPSEC option has been removed from GENERIC. Users requiring 649 ipsec(4) must now load the ipsec(4) kernel module. 650 65120190507: 652 The tap(4) driver has been folded into tun(4), and the module has been 653 renamed to tuntap. You should update any kld_list="if_tap" or 654 kld_list="if_tun" entries in /etc/rc.conf, if_tap_load="YES" or 655 if_tun_load="YES" entries in /boot/loader.conf to load the if_tuntap 656 module instead, and "device tap" or "device tun" entries in kernel 657 config files to select the tuntap device instead. 658 65920190418: 660 The following knobs have been added related to tradeoffs between 661 safe use of the random device and availability in the absence of 662 entropy: 663 664 kern.random.initial_seeding.bypass_before_seeding: tunable; set 665 non-zero to bypass the random device prior to seeding, or zero to 666 block random requests until the random device is initially seeded. 667 For now, set to 1 (unsafe) by default to restore pre-r346250 boot 668 availability properties. 669 670 kern.random.initial_seeding.read_random_bypassed_before_seeding: 671 read-only diagnostic sysctl that is set when bypass is enabled and 672 read_random(9) is bypassed, to enable programmatic handling of this 673 initial condition, if desired. 674 675 kern.random.initial_seeding.arc4random_bypassed_before_seeding: 676 Similar to the above, but for for arc4random(9) initial seeding. 677 678 kern.random.initial_seeding.disable_bypass_warnings: tunable; set 679 non-zero to disable warnings in dmesg when the same conditions are 680 met as for the diagnostic sysctls above. Defaults to zero, i.e., 681 produce warnings in dmesg when the conditions are met. 682 68320190416: 684 The loadable random module KPI has changed; the random_infra_init() 685 routine now requires a 3rd function pointer for a bool (*)(void) 686 method that returns true if the random device is seeded (and 687 therefore unblocked). 688 68920190404: 690 r345895 reverts r320698. This implies that an nfsuserd(8) daemon 691 built from head sources between r320757 (July 6, 2017) and 692 r338192 (Aug. 22, 2018) will not work unless the "-use-udpsock" 693 is added to the command line. 694 nfsuserd daemons built from head sources that are post-r338192 are 695 not affected and should continue to work. 696 69720190320: 698 The fuse(4) module has been renamed to fusefs(4) for consistency with 699 other filesystems. You should update any kld_load="fuse" entries in 700 /etc/rc.conf, fuse_load="YES" entries in /boot/loader.conf, and 701 "options FUSE" entries in kernel config files. 702 70320190304: 704 Clang, llvm, lld, lldb, compiler-rt and libc++ have been upgraded to 705 8.0.0. Please see the 20141231 entry below for information about 706 prerequisites and upgrading, if you are not already using clang 3.5.0 707 or higher. 708 70920190226: 710 geom_uzip(4) depends on the new module xz. If geom_uzip is statically 711 compiled into your custom kernel, add 'device xz' statement to the 712 kernel config. 713 71420190219: 715 drm and drm2 have been removed from the tree. Please see 716 https://wiki.freebsd.org/Graphics for the latest information on 717 migrating to the drm ports. 718 71920190131: 720 Iflib is no longer unconditionally compiled into the kernel. Drivers 721 using iflib and statically compiled into the kernel, now require 722 the 'device iflib' config option. For the same drivers loaded as 723 modules on kernels not having 'device iflib', the iflib.ko module 724 is loaded automatically. 725 72620190125: 727 The IEEE80211_AMPDU_AGE and AH_SUPPORT_AR5416 kernel configuration 728 options no longer exist since r343219 and r343427 respectively; 729 nothing uses them, so they should be just removed from custom 730 kernel config files. 731 73220181230: 733 r342635 changes the way efibootmgr(8) works by requiring users to add 734 the -b (bootnum) parameter for commands where the bootnum was previously 735 specified with each option. For example 'efibootmgr -B 0001' is now 736 'efibootmgr -B -b 0001'. 737 73820181220: 739 r342286 modifies the NFSv4 server so that it obeys vfs.nfsd.nfs_privport 740 in the same as it is applied to NFSv2 and 3. This implies that NFSv4 741 servers that have vfs.nfsd.nfs_privport set will only allow mounts 742 from clients using a reserved port. Since both the FreeBSD and Linux 743 NFSv4 clients use reserved ports by default, this should not affect 744 most NFSv4 mounts. 745 74620181219: 747 The XLP config has been removed. We can't support 64-bit atomics in this 748 kernel because it is running in 32-bit mode. XLP users must transition 749 to running a 64-bit kernel (XLP64 or XLPN32). 750 751 The mips GXEMUL support has been removed from FreeBSD. MALTA* + qemu is 752 the preferred emulator today and we don't need two different ones. 753 754 The old sibyte / swarm / Broadcom BCM1250 support has been 755 removed from the mips port. 756 75720181211: 758 Clang, llvm, lld, lldb, compiler-rt and libc++ have been upgraded to 759 7.0.1. Please see the 20141231 entry below for information about 760 prerequisites and upgrading, if you are not already using clang 3.5.0 761 or higher. 762 76320181211: 764 Remove the timed and netdate programs from the base tree. Setting 765 the time with these daemons has been obsolete for over a decade. 766 76720181126: 768 On amd64, arm64 and armv7 (architectures that install LLVM's ld.lld 769 linker as /usr/bin/ld) GNU ld is no longer installed as ld.bfd, as 770 it produces broken binaries when ifuncs are in use. Users needing 771 GNU ld should install the binutils port or package. 772 77320181123: 774 The BSD crtbegin and crtend code has been enabled by default. It has 775 had extensive testing on amd64, arm64, and i386. It can be disabled 776 by building a world with -DWITHOUT_BSD_CRTBEGIN. 777 77820181115: 779 The set of CTM commands (ctm, ctm_smail, ctm_rmail, ctm_dequeue) 780 has been converted to a port (misc/ctm) and will be removed from 781 FreeBSD-13. It is available as a package (ctm) for all supported 782 FreeBSD versions. 783 78420181110: 785 The default newsyslog.conf(5) file has been changed to only include 786 files in /etc/newsyslog.conf.d/ and /usr/local/etc/newsyslog.conf.d/ if 787 the filenames end in '.conf' and do not begin with a '.'. 788 789 You should check the configuration files in these two directories match 790 this naming convention. You can verify which configuration files are 791 being included using the command: 792 $ newsyslog -Nrv 793 79420181015: 795 Ports for the DRM modules have been simplified. Now, amd64 users should 796 just install the drm-kmod port. All others should install 797 drm-legacy-kmod. 798 799 Graphics hardware that's newer than about 2010 usually works with 800 drm-kmod. For hardware older than 2013, however, some users will need 801 to use drm-legacy-kmod if drm-kmod doesn't work for them. Hardware older 802 than 2008 usually only works in drm-legacy-kmod. The graphics team can 803 only commit to hardware made since 2013 due to the complexity of the 804 market and difficulty to test all the older cards effectively. If you 805 have hardware supported by drm-kmod, you are strongly encouraged to use 806 that as you will get better support. 807 808 Other than KPI chasing, drm-legacy-kmod will not be updated. As outlined 809 elsewhere, the drm and drm2 modules will be eliminated from the src base 810 soon (with a limited exception for arm). Please update to the package 811 asap and report any issues to x11@freebsd.org. 812 813 Generally, anybody using the drm*-kmod packages should add 814 WITHOUT_DRM_MODULE=t and WITHOUT_DRM2_MODULE=t to avoid nasty 815 cross-threading surprises, especially with automatic driver 816 loading from X11 startup. These will become the defaults in 13-current 817 shortly. 818 81920181012: 820 The ixlv(4) driver has been renamed to iavf(4). As a consequence, 821 custom kernel and module loading configuration files must be updated 822 accordingly. Moreover, interfaces previous presented as ixlvN to the 823 system are now exposed as iavfN and network configuration files must 824 be adjusted as necessary. 825 82620181009: 827 OpenSSL has been updated to version 1.1.1. This update included 828 additional various API changes throughout the base system. It is 829 important to rebuild third-party software after upgrading. The value 830 of __FreeBSD_version has been bumped accordingly. 831 83220181006: 833 The legacy DRM modules and drivers have now been added to the loader's 834 module blacklist, in favor of loading them with kld_list in rc.conf(5). 835 The module blacklist may be overridden with the loader.conf(5) 836 'module_blacklist' variable, but loading them via rc.conf(5) is strongly 837 encouraged. 838 83920181002: 840 The cam(4) based nda(4) driver will be used over nvd(4) by default on 841 powerpc64. You may set 'options NVME_USE_NVD=1' in your kernel conf or 842 loader tunable 'hw.nvme.use_nvd=1' if you wish to use the existing 843 driver. Make sure to edit /boot/etc/kboot.conf and fstab to use the 844 nda device name. 845 84620180913: 847 Reproducible build mode is now on by default, in preparation for 848 FreeBSD 12.0. This eliminates build metadata such as the user, 849 host, and time from the kernel (and uname), unless the working tree 850 corresponds to a modified checkout from a version control system. 851 The previous behavior can be obtained by setting the /etc/src.conf 852 knob WITHOUT_REPRODUCIBLE_BUILD. 853 85420180826: 855 The Yarrow CSPRNG has been removed from the kernel as it has not been 856 supported by its designers since at least 2003. Fortuna has been the 857 default since FreeBSD-11. 858 85920180822: 860 devctl freeze/thaw have gone into the tree, the rc scripts have been 861 updated to use them and devmatch has been changed. You should update 862 kernel, userland and rc scripts all at the same time. 863 86420180818: 865 The default interpreter has been switched from 4th to Lua. 866 LOADER_DEFAULT_INTERP, documented in build(7), will override the default 867 interpreter. If you have custom FORTH code you will need to set 868 LOADER_DEFAULT_INTERP=4th (valid values are 4th, lua or simp) in 869 src.conf for the build. This will create default hard links between 870 loader and loader_4th instead of loader and loader_lua, the new default. 871 If you are using UEFI it will create the proper hard link to loader.efi. 872 873 bhyve uses userboot.so. It remains 4th-only until some issues are solved 874 regarding coexisting with multiple versions of FreeBSD are resolved. 875 87620180815: 877 ls(1) now respects the COLORTERM environment variable used in other 878 systems and software to indicate that a colored terminal is both 879 supported and desired. If ls(1) is suddenly emitting colors, they may 880 be disabled again by either removing the unwanted COLORTERM from your 881 environment, or using `ls --color=never`. The ls(1) specific CLICOLOR 882 may not be observed in a future release. 883 88420180808: 885 The default pager for most commands has been changed to "less". To 886 restore the old behavior, set PAGER="more" and MANPAGER="more -s" in 887 your environment. 888 88920180731: 890 The jedec_ts(4) driver has been removed. A superset of its functionality 891 is available in the jedec_dimm(4) driver, and the manpage for that 892 driver includes migration instructions. If you have "device jedec_ts" 893 in your kernel configuration file, it must be removed. 894 89520180730: 896 amd64/GENERIC now has EFI runtime services, EFIRT, enabled by default. 897 This should have no effect if the kernel is booted via BIOS/legacy boot. 898 EFIRT may be disabled via a loader tunable, efi.rt.disabled, if a system 899 has a buggy firmware that prevents a successful boot due to use of 900 runtime services. 901 90220180727: 903 Atmel AT91RM9200 and AT91SAM9, Cavium CNS 11xx and XScale 904 support has been removed from the tree. These ports were 905 obsolete and/or known to be broken for many years. 906 90720180723: 908 loader.efi has been augmented to participate more fully in the 909 UEFI boot manager protocol. loader.efi will now look at the 910 BootXXXX environment variable to determine if a specific kernel 911 or root partition was specified. XXXX is derived from BootCurrent. 912 efibootmgr(8) manages these standard UEFI variables. 913 91420180720: 915 zfsloader's functionality has now been folded into loader. 916 zfsloader is no longer necessary once you've updated your 917 boot blocks. For a transition period, we will install a 918 hardlink for zfsloader to loader to allow a smooth transition 919 until the boot blocks can be updated (hard link because old 920 zfs boot blocks don't understand symlinks). 921 92220180719: 923 ARM64 now have efifb support, if you want to have serial console 924 on your arm64 board when an screen is connected and the bootloader 925 setup a frame buffer for us to use, just add : 926 boot_serial=YES 927 boot_multicons=YES 928 in /boot/loader.conf 929 For Raspberry Pi 3 (RPI) users, this is needed even if you don't have 930 an screen connected as the firmware will setup a frame buffer are that 931 u-boot will expose as an EFI frame buffer. 932 93320180719: 934 New uid:gid added, ntpd:ntpd (123:123). Be sure to run mergemaster 935 or take steps to update /etc/passwd before doing installworld on 936 existing systems. Do not skip the "mergemaster -Fp" step before 937 installworld, as described in the update procedures near the bottom 938 of this document. Also, rc.d/ntpd now starts ntpd(8) as user ntpd 939 if the new mac_ntpd(4) policy is available, unless ntpd_flags or 940 the ntp config file contain options that change file/dir locations. 941 When such options (e.g., "statsdir" or "crypto") are used, ntpd can 942 still be run as non-root by setting ntpd_user=ntpd in rc.conf, after 943 taking steps to ensure that all required files/dirs are accessible 944 by the ntpd user. 945 94620180717: 947 Big endian arm support has been removed. 948 94920180711: 950 The static environment setup in kernel configs is no longer mutually 951 exclusive with the loader(8) environment by default. In order to 952 restore the previous default behavior of disabling the loader(8) 953 environment if a static environment is present, you must specify 954 loader_env.disabled=1 in the static environment. 955 95620180705: 957 The ABI of syscalls used by management tools like sockstat and 958 netstat has been broken to allow 32-bit binaries to work on 959 64-bit kernels without modification. These programs will need 960 to match the kernel in order to function. External programs may 961 require minor modifications to accommodate a change of type in 962 structures from pointers to 64-bit virtual addresses. 963 96420180702: 965 On i386 and amd64 atomics are now inlined. Out of tree modules using 966 atomics will need to be rebuilt. 967 96820180701: 969 The '%I' format in the kern.corefile sysctl limits the number of 970 core files that a process can generate to the number stored in the 971 debug.ncores sysctl. The '%I' format is replaced by the single digit 972 index. Previously, if all indexes were taken the kernel would overwrite 973 only a core file with the highest index in a filename. 974 Currently the system will create a new core file if there is a free 975 index or if all slots are taken it will overwrite the oldest one. 976 97720180630: 978 Clang, llvm, lld, lldb, compiler-rt and libc++ have been upgraded to 979 6.0.1. Please see the 20141231 entry below for information about 980 prerequisites and upgrading, if you are not already using clang 3.5.0 981 or higher. 982 98320180628: 984 r335753 introduced a new quoting method. However, etc/devd/devmatch.conf 985 needed to be changed to work with it. This change was made with r335763 986 and requires a mergemaster / etcupdate / etc to update the installed 987 file. 988 98920180612: 990 r334930 changed the interface between the NFS modules, so they all 991 need to be rebuilt. r335018 did a __FreeBSD_version bump for this. 992 99320180530: 994 As of r334391 lld is the default amd64 system linker; it is installed 995 as /usr/bin/ld. Kernel build workarounds (see 20180510 entry) are no 996 longer necessary. 997 99820180530: 999 The kernel / userland interface for devinfo changed, so you'll 1000 need a new kernel and userland as a pair for it to work (rebuilding 1001 lib/libdevinfo is all that's required). devinfo and devmatch will 1002 not work, but everything else will when there's a mismatch. 1003 100420180523: 1005 The on-disk format for hwpmc callchain records has changed to include 1006 threadid corresponding to a given record. This changes the field offsets 1007 and thus requires that libpmcstat be rebuilt before using a kernel 1008 later than r334108. 1009 101020180517: 1011 The vxge(4) driver has been removed. This driver was introduced into 1012 HEAD one week before the Exar left the Ethernet market and is not 1013 known to be used. If you have device vxge in your kernel config file 1014 it must be removed. 1015 101620180510: 1017 The amd64 kernel now requires a ld that supports ifunc to produce a 1018 working kernel, either lld or a newer binutils. lld is built by default 1019 on amd64, and the 'buildkernel' target uses it automatically. However, 1020 it is not the default linker, so building the kernel the traditional 1021 way requires LD=ld.lld on the command line (or LD=/usr/local/bin/ld for 1022 binutils port/package). lld will soon be default, and this requirement 1023 will go away. 1024 1025 NOTE: As of r334391 lld is the default system linker on amd64, and no 1026 workaround is necessary. 1027 102820180508: 1029 The nxge(4) driver has been removed. This driver was for PCI-X 10g 1030 cards made by s2io/Neterion. The company was acquired by Exar and 1031 no longer sells or supports Ethernet products. If you have device 1032 nxge in your kernel config file it must be removed. 1033 103420180504: 1035 The tz database (tzdb) has been updated to 2018e. This version more 1036 correctly models time stamps in time zones with negative DST such as 1037 Europe/Dublin (from 1971 on), Europe/Prague (1946/7), and 1038 Africa/Windhoek (1994/2017). This does not affect the UT offsets, only 1039 time zone abbreviations and the tm_isdst flag. 1040 104120180502: 1042 The ixgb(4) driver has been removed. This driver was for an early and 1043 uncommon legacy PCI 10GbE for a single ASIC, Intel 82597EX. Intel 1044 quickly shifted to the long lived ixgbe family. If you have device 1045 ixgb in your kernel config file it must be removed. 1046 104720180501: 1048 The lmc(4) driver has been removed. This was a WAN interface 1049 card that was already reportedly rare in 2003, and had an ambiguous 1050 license. If you have device lmc in your kernel config file it must 1051 be removed. 1052 105320180413: 1054 Support for Arcnet networks has been removed. If you have device 1055 arcnet or device cm in your kernel config file they must be 1056 removed. 1057 105820180411: 1059 Support for FDDI networks has been removed. If you have device 1060 fddi or device fpa in your kernel config file they must be 1061 removed. 1062 106320180406: 1064 In addition to supporting RFC 3164 formatted messages, the 1065 syslogd(8) service is now capable of parsing RFC 5424 formatted 1066 log messages. The main benefit of using RFC 5424 is that clients 1067 may now send log messages with timestamps containing year numbers, 1068 microseconds and time zone offsets. 1069 1070 Similarly, the syslog(3) C library function has been altered to 1071 send RFC 5424 formatted messages to the local system logging 1072 daemon. On systems using syslogd(8), this change should have no 1073 negative impact, as long as syslogd(8) and the C library are 1074 updated at the same time. On systems using a different system 1075 logging daemon, it may be necessary to make configuration 1076 adjustments, depending on the software used. 1077 1078 When using syslog-ng, add the 'syslog-protocol' flag to local 1079 input sources to enable parsing of RFC 5424 formatted messages: 1080 1081 source src { 1082 unix-dgram("/var/run/log" flags(syslog-protocol)); 1083 } 1084 1085 When using rsyslog, disable the 'SysSock.UseSpecialParser' option 1086 of the 'imuxsock' module to let messages be processed by the 1087 regular RFC 3164/5424 parsing pipeline: 1088 1089 module(load="imuxsock" SysSock.UseSpecialParser="off") 1090 1091 Do note that these changes only affect communication between local 1092 applications and syslogd(8). The format that syslogd(8) uses to 1093 store messages on disk or forward messages to other systems 1094 remains unchanged. syslogd(8) still uses RFC 3164 for these 1095 purposes. Options to customize this behaviour will be added in the 1096 future. Utilities that process log files stored in /var/log are 1097 thus expected to continue to function as before. 1098 1099 __FreeBSD_version has been incremented to 1200061 to denote this 1100 change. 1101 110220180328: 1103 Support for token ring networks has been removed. If you 1104 have "device token" in your kernel config you should remove 1105 it. No device drivers supported token ring. 1106 110720180323: 1108 makefs was modified to be able to tag ISO9660 El Torito boot catalog 1109 entries as EFI instead of overloading the i386 tag as done previously. 1110 The amd64 mkisoimages.sh script used to build amd64 ISO images for 1111 release was updated to use this. This may mean that makefs must be 1112 updated before "make cdrom" can be run in the release directory. This 1113 should be as simple as: 1114 1115 $ cd $SRCDIR/usr.sbin/makefs 1116 $ make depend all install 1117 111820180212: 1119 FreeBSD boot loader enhanced with Lua scripting. It's purely opt-in for 1120 now by building WITH_LOADER_LUA and WITHOUT_FORTH in /etc/src.conf. 1121 Co-existence for the transition period will come shortly. Booting is a 1122 complex environment and test coverage for Lua-enabled loaders has been 1123 thin, so it would be prudent to assume it might not work and make 1124 provisions for backup boot methods. 1125 112620180211: 1127 devmatch functionality has been turned on in devd. It will automatically 1128 load drivers for unattached devices. This may cause unexpected drivers 1129 to be loaded. Please report any problems to current@ and 1130 imp@freebsd.org. 1131 113220180114: 1133 Clang, llvm, lld, lldb, compiler-rt and libc++ have been upgraded to 1134 6.0.0. Please see the 20141231 entry below for information about 1135 prerequisites and upgrading, if you are not already using clang 3.5.0 1136 or higher. 1137 113820180110: 1139 LLVM's lld linker is now used as the FreeBSD/amd64 bootstrap linker. 1140 This means it is used to link the kernel and userland libraries and 1141 executables, but is not yet installed as /usr/bin/ld by default. 1142 1143 To revert to ld.bfd as the bootstrap linker, in /etc/src.conf set 1144 WITHOUT_LLD_BOOTSTRAP=yes 1145 114620180110: 1147 On i386, pmtimer has been removed. Its functionality has been folded 1148 into apm. It was a no-op on ACPI in current for a while now (but was 1149 still needed on i386 in FreeBSD 11 and earlier). Users may need to 1150 remove it from kernel config files. 1151 115220180104: 1153 The use of RSS hash from the network card aka flowid has been 1154 disabled by default for lagg(4) as it's currently incompatible with 1155 the lacp and loadbalance protocols. 1156 1157 This can be re-enabled by setting the following in loader.conf: 1158 net.link.lagg.default_use_flowid="1" 1159 116020180102: 1161 The SW_WATCHDOG option is no longer necessary to enable the 1162 hardclock-based software watchdog if no hardware watchdog is 1163 configured. As before, SW_WATCHDOG will cause the software 1164 watchdog to be enabled even if a hardware watchdog is configured. 1165 116620171215: 1167 r326887 fixes the issue described in the 20171214 UPDATING entry. 1168 r326888 flips the switch back to building GELI support always. 1169 117020171214: 1171 r362593 broke ZFS + GELI support for reasons unknown. However, 1172 it also broke ZFS support generally, so GELI has been turned off 1173 by default as the lesser evil in r326857. If you boot off ZFS and/or 1174 GELI, it might not be a good time to update. 1175 117620171125: 1177 PowerPC users must update loader(8) by rebuilding world before 1178 installing a new kernel, as the protocol connecting them has 1179 changed. Without the update, loader metadata will not be passed 1180 successfully to the kernel and users will have to enter their 1181 root partition at the kernel mountroot prompt to continue booting. 1182 Newer versions of loader can boot old kernels without issue. 1183 118420171110: 1185 The LOADER_FIREWIRE_SUPPORT build variable has been renamed to 1186 WITH/OUT_LOADER_FIREWIRE. LOADER_{NO_,}GELI_SUPPORT has been renamed 1187 to WITH/OUT_LOADER_GELI. 1188 118920171106: 1190 The naive and non-compliant support of posix_fallocate(2) in ZFS 1191 has been removed as of r325320. The system call now returns EINVAL 1192 when used on a ZFS file. Although the new behavior complies with the 1193 standard, some consumers are not prepared to cope with it. 1194 One known victim is lld prior to r325420. 1195 119620171102: 1197 Building in a FreeBSD src checkout will automatically create object 1198 directories now rather than store files in the current directory if 1199 'make obj' was not ran. Calling 'make obj' is no longer necessary. 1200 This feature can be disabled by setting WITHOUT_AUTO_OBJ=yes in 1201 /etc/src-env.conf (not /etc/src.conf), or passing the option in the 1202 environment. 1203 120420171101: 1205 The default MAKEOBJDIR has changed from /usr/obj/<srcdir> for native 1206 builds, and /usr/obj/<arch>/<srcdir> for cross-builds, to a unified 1207 /usr/obj/<srcdir>/<arch>. This behavior can be changed to the old 1208 format by setting WITHOUT_UNIFIED_OBJDIR=yes in /etc/src-env.conf, 1209 the environment, or with -DWITHOUT_UNIFIED_OBJDIR when building. 1210 The UNIFIED_OBJDIR option is a transitional feature that will be 1211 removed for 12.0 release; please migrate to the new format for any 1212 tools by looking up the OBJDIR used by 'make -V .OBJDIR' means rather 1213 than hardcoding paths. 1214 121520171028: 1216 The native-xtools target no longer installs the files by default to the 1217 OBJDIR. Use the native-xtools-install target with a DESTDIR to install 1218 to ${DESTDIR}/${NXTP} where NXTP defaults to /nxb-bin. 1219 122020171021: 1221 As part of the boot loader infrastructure cleanup, LOADER_*_SUPPORT 1222 options are changing from controlling the build if defined / undefined 1223 to controlling the build with explicit 'yes' or 'no' values. They will 1224 shift to WITH/WITHOUT options to match other options in the system. 1225 122620171010: 1227 libstand has turned into a private library for sys/boot use only. 1228 It is no longer supported as a public interface outside of sys/boot. 1229 123020171005: 1231 The arm port has split armv6 into armv6 and armv7. armv7 is now 1232 a valid TARGET_ARCH/MACHINE_ARCH setting. If you have an armv7 system 1233 and are running a kernel from before r324363, you will need to add 1234 MACHINE_ARCH=armv7 to 'make buildworld' to do a native build. 1235 123620171003: 1237 When building multiple kernels using KERNCONF, non-existent KERNCONF 1238 files will produce an error and buildkernel will fail. Previously 1239 missing KERNCONF files silently failed giving no indication as to 1240 why, only to subsequently discover during installkernel that the 1241 desired kernel was never built in the first place. 1242 124320170912: 1244 The default serial number format for CTL LUNs has changed. This will 1245 affect users who use /dev/diskid/* device nodes, or whose FibreChannel 1246 or iSCSI clients care about their LUNs' serial numbers. Users who 1247 require serial number stability should hardcode serial numbers in 1248 /etc/ctl.conf . 1249 125020170912: 1251 For 32-bit arm compiled for hard-float support, soft-floating point 1252 binaries now always get their shared libraries from 1253 LD_SOFT_LIBRARY_PATH (in the past, this was only used if 1254 /usr/libsoft also existed). Only users with a hard-float ld.so, but 1255 soft-float everything else should be affected. 1256 125720170826: 1258 The geli password typed at boot is now hidden. To restore the previous 1259 behavior, see geli(8) for configuration options. 1260 126120170825: 1262 Move PMTUD blackhole counters to TCPSTATS and remove them from bare 1263 sysctl values. Minor nit, but requires a rebuild of both world/kernel 1264 to complete. 1265 126620170814: 1267 "make check" behavior (made in ^/head@r295380) has been changed to 1268 execute from a limited sandbox, as opposed to executing from 1269 ${TESTSDIR}. 1270 1271 Behavioral changes: 1272 - The "beforecheck" and "aftercheck" targets are now specified. 1273 - ${CHECKDIR} (added in commit noted above) has been removed. 1274 - Legacy behavior can be enabled by setting 1275 WITHOUT_MAKE_CHECK_USE_SANDBOX in src.conf(5) or the environment. 1276 1277 If the limited sandbox mode is enabled, "make check" will execute 1278 "make distribution", then install, execute the tests, and clean up the 1279 sandbox if successful. 1280 1281 The "make distribution" and "make install" targets are typically run as 1282 root to set appropriate permissions and ownership at installation time. 1283 The end-user should set "WITH_INSTALL_AS_USER" in src.conf(5) or the 1284 environment if executing "make check" with limited sandbox mode using 1285 an unprivileged user. 1286 128720170808: 1288 Since the switch to GPT disk labels, fsck for UFS/FFS has been 1289 unable to automatically find alternate superblocks. As of r322297, 1290 the information needed to find alternate superblocks has been 1291 moved to the end of the area reserved for the boot block. 1292 Filesystems created with a newfs of this vintage or later 1293 will create the recovery information. If you have a filesystem 1294 created prior to this change and wish to have a recovery block 1295 created for your filesystem, you can do so by running fsck in 1296 foreground mode (i.e., do not use the -p or -y options). As it 1297 starts, fsck will ask ``SAVE DATA TO FIND ALTERNATE SUPERBLOCKS'' 1298 to which you should answer yes. 1299 130020170728: 1301 As of r321665, an NFSv4 server configuration that services 1302 Kerberos mounts or clients that do not support the uid/gid in 1303 owner/owner_group string capability, must explicitly enable 1304 the nfsuserd daemon by adding nfsuserd_enable="YES" to the 1305 machine's /etc/rc.conf file. 1306 130720170722: 1308 Clang, llvm, lldb, compiler-rt and libc++ have been upgraded to 5.0.0. 1309 Please see the 20141231 entry below for information about prerequisites 1310 and upgrading, if you are not already using clang 3.5.0 or higher. 1311 131220170701: 1313 WITHOUT_RCMDS is now the default. Set WITH_RCMDS if you need the 1314 r-commands (rlogin, rsh, etc.) to be built with the base system. 1315 131620170625: 1317 The FreeBSD/powerpc platform now uses a 64-bit type for time_t. This is 1318 a very major ABI incompatible change, so users of FreeBSD/powerpc must 1319 be careful when performing source upgrades. It is best to run 1320 'make installworld' from an alternate root system, either a live 1321 CD/memory stick, or a temporary root partition. Additionally, all ports 1322 must be recompiled. powerpc64 is largely unaffected, except in the case 1323 of 32-bit compatibility. All 32-bit binaries will be affected. 1324 132520170623: 1326 Forward compatibility for the "ino64" project have been committed. This 1327 will allow most new binaries to run on older kernels in a limited 1328 fashion. This prevents many of the common foot-shooting actions in the 1329 upgrade as well as the limited ability to roll back the kernel across 1330 the ino64 upgrade. Complicated use cases may not work properly, though 1331 enough simpler ones work to allow recovery in most situations. 1332 133320170620: 1334 Switch back to the BSDL dtc (Device Tree Compiler). Set WITH_GPL_DTC 1335 if you require the GPL compiler. 1336 133720170618: 1338 The internal ABI used for communication between the NFS kernel modules 1339 was changed by r320085, so __FreeBSD_version was bumped to 1340 ensure all the NFS related modules are updated together. 1341 134220170617: 1343 The ABI of struct event was changed by extending the data 1344 member to 64bit and adding ext fields. For upgrade, same 1345 precautions as for the entry 20170523 "ino64" must be 1346 followed. 1347 134820170531: 1349 The GNU roff toolchain has been removed from base. To render manpages 1350 which are not supported by mandoc(1), man(1) can fallback on GNU roff 1351 from ports (and recommends to install it). 1352 To render roff(7) documents, consider using GNU roff from ports or the 1353 heirloom doctools roff toolchain from ports via pkg install groff or 1354 via pkg install heirloom-doctools. 1355 135620170524: 1357 The ath(4) and ath_hal(4) modules now build piecemeal to allow for 1358 smaller runtime footprint builds. This is useful for embedded systems 1359 which only require one chipset support. 1360 1361 If you load it as a module, make sure this is in /boot/loader.conf: 1362 1363 if_ath_load="YES" 1364 1365 This will load the HAL, all chip/RF backends and if_ath_pci. 1366 If you have if_ath_pci in /boot/loader.conf, ensure it is after 1367 if_ath or it will not load any HAL chipset support. 1368 1369 If you want to selectively load things (eg on cheaper ARM/MIPS 1370 platforms where RAM is at a premium) you should: 1371 1372 * load ath_hal 1373 * load the chip modules in question 1374 * load ath_rate, ath_dfs 1375 * load ath_main 1376 * load if_ath_pci and/or if_ath_ahb depending upon your particular 1377 bus bind type - this is where probe/attach is done. 1378 1379 For further comments/feedback, poke adrian@ . 1380 138120170523: 1382 The "ino64" 64-bit inode project has been committed, which extends 1383 a number of types to 64 bits. Upgrading in place requires care and 1384 adherence to the documented upgrade procedure. 1385 1386 If using a custom kernel configuration ensure that the 1387 COMPAT_FREEBSD11 option is included (as during the upgrade the 1388 system will be running the ino64 kernel with the existing world). 1389 1390 For the safest in-place upgrade begin by removing previous build 1391 artifacts via "rm -rf /usr/obj/*". Then, carefully follow the full 1392 procedure documented below under the heading "To rebuild everything and 1393 install it on the current system." Specifically, a reboot is required 1394 after installing the new kernel before installing world. While an 1395 installworld normally works by accident from multiuser after rebooting 1396 the proper kernel, there are many cases where this will fail across this 1397 upgrade and installworld from single user is required. 1398 139920170424: 1400 The NATM framework including the en(4), fatm(4), hatm(4), and 1401 patm(4) devices has been removed. Consumers should plan a 1402 migration before the end-of-life date for FreeBSD 11. 1403 140420170420: 1405 GNU diff has been replaced by a BSD licensed diff. Some features of GNU 1406 diff has not been implemented, if those are needed a newer version of 1407 GNU diff is available via the diffutils package under the gdiff name. 1408 140920170413: 1410 As of r316810 for ipfilter, keep frags is no longer assumed when 1411 keep state is specified in a rule. r316810 aligns ipfilter with 1412 documentation in man pages separating keep frags from keep state. 1413 This allows keep state to be specified without forcing keep frags 1414 and allows keep frags to be specified independently of keep state. 1415 To maintain previous behaviour, also specify keep frags with 1416 keep state (as documented in ipf.conf.5). 1417 141820170407: 1419 arm64 builds now use the base system LLD 4.0.0 linker by default, 1420 instead of requiring that the aarch64-binutils port or package be 1421 installed. To continue using aarch64-binutils, set 1422 CROSS_BINUTILS_PREFIX=/usr/local/aarch64-freebsd/bin . 1423 142420170405: 1425 The UDP optimization in entry 20160818 that added the sysctl 1426 net.inet.udp.require_l2_bcast has been reverted. L2 broadcast 1427 packets will no longer be treated as L3 broadcast packets. 1428 142920170331: 1430 Binds and sends to the loopback addresses, IPv6 and IPv4, will now 1431 use any explicitly assigned loopback address available in the jail 1432 instead of using the first assigned address of the jail. 1433 143420170329: 1435 The ctl.ko module no longer implements the iSCSI target frontend: 1436 cfiscsi.ko does instead. 1437 1438 If building cfiscsi.ko as a kernel module, the module can be loaded 1439 via one of the following methods: 1440 - `cfiscsi_load="YES"` in loader.conf(5). 1441 - Add `cfiscsi` to `$kld_list` in rc.conf(5). 1442 - ctladm(8)/ctld(8), when compiled with iSCSI support 1443 (`WITH_ISCSI=yes` in src.conf(5)) 1444 1445 Please see cfiscsi(4) for more details. 1446 144720170316: 1448 The mmcsd.ko module now additionally depends on geom_flashmap.ko. 1449 Also, mmc.ko and mmcsd.ko need to be a matching pair built from the 1450 same source (previously, the dependency of mmcsd.ko on mmc.ko was 1451 missing, but mmcsd.ko now will refuse to load if it is incompatible 1452 with mmc.ko). 1453 145420170315: 1455 The syntax of ipfw(8) named states was changed to avoid ambiguity. 1456 If you have used named states in the firewall rules, you need to modify 1457 them after installworld and before rebooting. Now named states must 1458 be prefixed with colon. 1459 146020170311: 1461 The old drm (sys/dev/drm/) drivers for i915 and radeon have been 1462 removed as the userland we provide cannot use them. The KMS version 1463 (sys/dev/drm2) supports the same hardware. 1464 146520170302: 1466 Clang, llvm, lldb, compiler-rt and libc++ have been upgraded to 4.0.0. 1467 Please see the 20141231 entry below for information about prerequisites 1468 and upgrading, if you are not already using clang 3.5.0 or higher. 1469 147020170221: 1471 The code that provides support for ZFS .zfs/ directory functionality 1472 has been reimplemented. It's not possible now to create a snapshot 1473 by mkdir under .zfs/snapshot/. That should be the only user visible 1474 change. 1475 147620170216: 1477 EISA bus support has been removed. The WITH_EISA option is no longer 1478 valid. 1479 148020170215: 1481 MCA bus support has been removed. 1482 148320170127: 1484 The WITH_LLD_AS_LD / WITHOUT_LLD_AS_LD build knobs have been renamed 1485 WITH_LLD_IS_LD / WITHOUT_LLD_IS_LD, for consistency with CLANG_IS_CC. 1486 148720170112: 1488 The EM_MULTIQUEUE kernel configuration option is deprecated now that 1489 the em(4) driver conforms to iflib specifications. 1490 149120170109: 1492 The igb(4), em(4) and lem(4) ethernet drivers are now implemented via 1493 IFLIB. If you have a custom kernel configuration that excludes em(4) 1494 but you use igb(4), you need to re-add em(4) to your custom 1495 configuration. 1496 149720161217: 1498 Clang, llvm, lldb, compiler-rt and libc++ have been upgraded to 3.9.1. 1499 Please see the 20141231 entry below for information about prerequisites 1500 and upgrading, if you are not already using clang 3.5.0 or higher. 1501 150220161124: 1503 Clang, llvm, lldb, compiler-rt and libc++ have been upgraded to 3.9.0. 1504 Please see the 20141231 entry below for information about prerequisites 1505 and upgrading, if you are not already using clang 3.5.0 or higher. 1506 150720161119: 1508 The layout of the pmap structure has changed for powerpc to put the pmap 1509 statistics at the front for all CPU variations. libkvm(3) and all tools 1510 that link against it need to be recompiled. 1511 151220161030: 1513 isl(4) and cyapa(4) drivers now require a new driver, 1514 chromebook_platform(4), to work properly on Chromebook-class hardware. 1515 On other types of hardware the drivers may need to be configured using 1516 device hints. Please see the corresponding manual pages for details. 1517 151820161017: 1519 The urtwn(4) driver was merged into rtwn(4) and now consists of 1520 rtwn(4) main module + rtwn_usb(4) and rtwn_pci(4) bus-specific 1521 parts. 1522 Also, firmware for RTL8188CE was renamed due to possible name 1523 conflict (rtwnrtl8192cU(B) -> rtwnrtl8192cE(B)) 1524 152520161015: 1526 GNU rcs has been removed from base. It is available as packages: 1527 - rcs: Latest GPLv3 GNU rcs version. 1528 - rcs57: Copy of the latest version of GNU rcs (GPLv2) before it was 1529 removed from base. 1530 153120161008: 1532 Use of the cc_cdg, cc_chd, cc_hd, or cc_vegas congestion control 1533 modules now requires that the kernel configuration contain the 1534 TCP_HHOOK option. (This option is included in the GENERIC kernel.) 1535 153620161003: 1537 The WITHOUT_ELFCOPY_AS_OBJCOPY src.conf(5) knob has been retired. 1538 ELF Tool Chain's elfcopy is always installed as /usr/bin/objcopy. 1539 154020160924: 1541 Relocatable object files with the extension of .So have been renamed 1542 to use an extension of .pico instead. The purpose of this change is 1543 to avoid a name clash with shared libraries on case-insensitive file 1544 systems. On those file systems, foo.So is the same file as foo.so. 1545 154620160918: 1547 GNU rcs has been turned off by default. It can (temporarily) be built 1548 again by adding WITH_RCS knob in src.conf. 1549 Otherwise, GNU rcs is available from packages: 1550 - rcs: Latest GPLv3 GNU rcs version. 1551 - rcs57: Copy of the latest version of GNU rcs (GPLv2) from base. 1552 155320160918: 1554 The backup_uses_rcs functionality has been removed from rc.subr. 1555 155620160908: 1557 The queue(3) debugging macro, QUEUE_MACRO_DEBUG, has been split into 1558 two separate components, QUEUE_MACRO_DEBUG_TRACE and 1559 QUEUE_MACRO_DEBUG_TRASH. Define both for the original 1560 QUEUE_MACRO_DEBUG behavior. 1561 156220160824: 1563 r304787 changed some ioctl interfaces between the iSCSI userspace 1564 programs and the kernel. ctladm, ctld, iscsictl, and iscsid must be 1565 rebuilt to work with new kernels. __FreeBSD_version has been bumped 1566 to 1200005. 1567 156820160818: 1569 The UDP receive code has been updated to only treat incoming UDP 1570 packets that were addressed to an L2 broadcast address as L3 1571 broadcast packets. It is not expected that this will affect any 1572 standards-conforming UDP application. The new behaviour can be 1573 disabled by setting the sysctl net.inet.udp.require_l2_bcast to 1574 0. 1575 157620160818: 1577 Remove the openbsd_poll system call. 1578 __FreeBSD_version has been bumped because of this. 1579 158020160708: 1581 The stable/11 branch has been created from head@r302406. 1582 158320160622: 1584 The libc stub for the pipe(2) system call has been replaced with 1585 a wrapper that calls the pipe2(2) system call and the pipe(2) 1586 system call is now only implemented by the kernels that include 1587 "options COMPAT_FREEBSD10" in their config file (this is the 1588 default). Users should ensure that this option is enabled in 1589 their kernel or upgrade userspace to r302092 before upgrading their 1590 kernel. 1591 159220160527: 1593 CAM now strips the leading spaces from each SCSI disk's serial number. 1594 This will affect users who create UFS filesystems on SCSI disks using 1595 those disk's diskid device nodes. For example, if /etc/fstab 1596 previously contained a line like 1597 "/dev/diskid/DISK-%20%20%20%20%20%20%20ABCDEFG0123456", you should 1598 change it to "/dev/diskid/DISK-ABCDEFG0123456". Users of geom 1599 transforms like gmirror may also be affected. ZFS users should 1600 generally be fine. 1601 160220160523: 1603 The bitstring(3) API has been updated with new functionality and 1604 improved performance. But it is binary-incompatible with the old API. 1605 Objects built with the new headers may not be linked against objects 1606 built with the old headers. 1607 160820160520: 1609 The brk and sbrk functions have been removed from libc on arm64. 1610 Binutils from ports has been updated to not link to these 1611 functions and should be updated to the latest version before 1612 installing a new libc. 1613 161420160517: 1615 The armv6 port now defaults to hard float ABI. Limited support 1616 for running both hardfloat and soft float on the same system 1617 is available using the libraries installed with -DWITH_LIBSOFT. 1618 This has only been tested as an upgrade path for installworld 1619 and packages may fail or need manual intervention to run. New 1620 packages will be needed. 1621 1622 To update an existing self-hosted armv6hf system, you must add 1623 TARGET_ARCH=armv6 on the make command line for both the build 1624 and the install steps. 1625 162620160510: 1627 Kernel modules compiled outside of a kernel build now default to 1628 installing to /boot/modules instead of /boot/kernel. Many kernel 1629 modules built this way (such as those in ports) already overrode 1630 KMODDIR explicitly to install into /boot/modules. However, 1631 manually building and installing a module from /sys/modules will 1632 now install to /boot/modules instead of /boot/kernel. 1633 163420160414: 1635 The CAM I/O scheduler has been committed to the kernel. There should be 1636 no user visible impact. This does enable NCQ Trim on ada SSDs. While the 1637 list of known rogues that claim support for this but actually corrupt 1638 data is believed to be complete, be on the lookout for data 1639 corruption. The known rogue list is believed to be complete: 1640 1641 o Crucial MX100, M550 drives with MU01 firmware. 1642 o Micron M510 and M550 drives with MU01 firmware. 1643 o Micron M500 prior to MU07 firmware 1644 o Samsung 830, 840, and 850 all firmwares 1645 o FCCT M500 all firmwares 1646 1647 Crucial has firmware http://www.crucial.com/usa/en/support-ssd-firmware 1648 with working NCQ TRIM. For Micron branded drives, see your sales rep for 1649 updated firmware. Black listed drives will work correctly because these 1650 drives work correctly so long as no NCQ TRIMs are sent to them. Given 1651 this list is the same as found in Linux, it's believed there are no 1652 other rogues in the market place. All other models from the above 1653 vendors work. 1654 1655 To be safe, if you are at all concerned, you can quirk each of your 1656 drives to prevent NCQ from being sent by setting: 1657 kern.cam.ada.X.quirks="0x2" 1658 in loader.conf. If the drive requires the 4k sector quirk, set the 1659 quirks entry to 0x3. 1660 166120160330: 1662 The FAST_DEPEND build option has been removed and its functionality is 1663 now the one true way. The old mkdep(1) style of 'make depend' has 1664 been removed. See 20160311 for further details. 1665 166620160317: 1667 Resource range types have grown from unsigned long to uintmax_t. All 1668 drivers, and anything using libdevinfo, need to be recompiled. 1669 167020160311: 1671 WITH_FAST_DEPEND is now enabled by default for in-tree and out-of-tree 1672 builds. It no longer runs mkdep(1) during 'make depend', and the 1673 'make depend' stage can safely be skipped now as it is auto ran 1674 when building 'make all' and will generate all SRCS and DPSRCS before 1675 building anything else. Dependencies are gathered at compile time with 1676 -MF flags kept in separate .depend files per object file. Users should 1677 run 'make cleandepend' once if using -DNO_CLEAN to clean out older 1678 stale .depend files. 1679 168020160306: 1681 On amd64, clang 3.8.0 can now insert sections of type AMD64_UNWIND into 1682 kernel modules. Therefore, if you load any kernel modules at boot time, 1683 please install the boot loaders after you install the kernel, but before 1684 rebooting, e.g.: 1685 1686 make buildworld 1687 make buildkernel KERNCONF=YOUR_KERNEL_HERE 1688 make installkernel KERNCONF=YOUR_KERNEL_HERE 1689 make -C sys/boot install 1690 <reboot in single user> 1691 1692 Then follow the usual steps, described in the General Notes section, 1693 below. 1694 169520160305: 1696 Clang, llvm, lldb and compiler-rt have been upgraded to 3.8.0. Please 1697 see the 20141231 entry below for information about prerequisites and 1698 upgrading, if you are not already using clang 3.5.0 or higher. 1699 170020160301: 1701 The AIO subsystem is now a standard part of the kernel. The 1702 VFS_AIO kernel option and aio.ko kernel module have been removed. 1703 Due to stability concerns, asynchronous I/O requests are only 1704 permitted on sockets and raw disks by default. To enable 1705 asynchronous I/O requests on all file types, set the 1706 vfs.aio.enable_unsafe sysctl to a non-zero value. 1707 170820160226: 1709 The ELF object manipulation tool objcopy is now provided by the 1710 ELF Tool Chain project rather than by GNU binutils. It should be a 1711 drop-in replacement, with the addition of arm64 support. The 1712 (temporary) src.conf knob WITHOUT_ELFCOPY_AS_OBJCOPY knob may be set 1713 to obtain the GNU version if necessary. 1714 171520160129: 1716 Building ZFS pools on top of zvols is prohibited by default. That 1717 feature has never worked safely; it's always been prone to deadlocks. 1718 Using a zvol as the backing store for a VM guest's virtual disk will 1719 still work, even if the guest is using ZFS. Legacy behavior can be 1720 restored by setting vfs.zfs.vol.recursive=1. 1721 172220160119: 1723 The NONE and HPN patches has been removed from OpenSSH. They are 1724 still available in the security/openssh-portable port. 1725 172620160113: 1727 With the addition of ypldap(8), a new _ypldap user is now required 1728 during installworld. "mergemaster -p" can be used to add the user 1729 prior to installworld, as documented in the handbook. 1730 173120151216: 1732 The tftp loader (pxeboot) now uses the option root-path directive. As a 1733 consequence it no longer looks for a pxeboot.4th file on the tftp 1734 server. Instead it uses the regular /boot infrastructure as with the 1735 other loaders. 1736 173720151211: 1738 The code to start recording plug and play data into the modules has 1739 been committed. While the old tools will properly build a new kernel, 1740 a number of warnings about "unknown metadata record 4" will be produced 1741 for an older kldxref. To avoid such warnings, make sure to rebuild 1742 the kernel toolchain (or world). Make sure that you have r292078 or 1743 later when trying to build 292077 or later before rebuilding. 1744 174520151207: 1746 Debug data files are now built by default with 'make buildworld' and 1747 installed with 'make installworld'. This facilitates debugging but 1748 requires more disk space both during the build and for the installed 1749 world. Debug files may be disabled by setting WITHOUT_DEBUG_FILES=yes 1750 in src.conf(5). 1751 175220151130: 1753 r291527 changed the internal interface between the nfsd.ko and 1754 nfscommon.ko modules. As such, they must both be upgraded to-gether. 1755 __FreeBSD_version has been bumped because of this. 1756 175720151108: 1758 Add support for unicode collation strings leads to a change of 1759 order of files listed by ls(1) for example. To get back to the old 1760 behaviour, set LC_COLLATE environment variable to "C". 1761 1762 Databases administrators will need to reindex their databases given 1763 collation results will be different. 1764 1765 Due to a bug in install(1) it is recommended to remove the ancient 1766 locales before running make installworld. 1767 1768 rm -rf /usr/share/locale/* 1769 177020151030: 1771 The OpenSSL has been upgraded to 1.0.2d. Any binaries requiring 1772 libcrypto.so.7 or libssl.so.7 must be recompiled. 1773 177420151020: 1775 Qlogic 24xx/25xx firmware images were updated from 5.5.0 to 7.3.0. 1776 Kernel modules isp_2400_multi and isp_2500_multi were removed and 1777 should be replaced with isp_2400 and isp_2500 modules respectively. 1778 177920151017: 1780 The build previously allowed using 'make -n' to not recurse into 1781 sub-directories while showing what commands would be executed, and 1782 'make -n -n' to recursively show commands. Now 'make -n' will recurse 1783 and 'make -N' will not. 1784 178520151012: 1786 If you specify SENDMAIL_MC or SENDMAIL_CF in make.conf, mergemaster 1787 and etcupdate will now use this file. A custom sendmail.cf is now 1788 updated via this mechanism rather than via installworld. If you had 1789 excluded sendmail.cf in mergemaster.rc or etcupdate.conf, you may 1790 want to remove the exclusion or change it to "always install". 1791 /etc/mail/sendmail.cf is now managed the same way regardless of 1792 whether SENDMAIL_MC/SENDMAIL_CF is used. If you are not using 1793 SENDMAIL_MC/SENDMAIL_CF there should be no change in behavior. 1794 179520151011: 1796 Compatibility shims for legacy ATA device names have been removed. 1797 It includes ATA_STATIC_ID kernel option, kern.cam.ada.legacy_aliases 1798 and kern.geom.raid.legacy_aliases loader tunables, kern.devalias.* 1799 environment variables, /dev/ad* and /dev/ar* symbolic links. 1800 180120151006: 1802 Clang, llvm, lldb, compiler-rt and libc++ have been upgraded to 3.7.0. 1803 Please see the 20141231 entry below for information about prerequisites 1804 and upgrading, if you are not already using clang 3.5.0 or higher. 1805 180620150924: 1807 Kernel debug files have been moved to /usr/lib/debug/boot/kernel/, 1808 and renamed from .symbols to .debug. This reduces the size requirements 1809 on the boot partition or file system and provides consistency with 1810 userland debug files. 1811 1812 When using the supported kernel installation method the 1813 /usr/lib/debug/boot/kernel directory will be renamed (to kernel.old) 1814 as is done with /boot/kernel. 1815 1816 Developers wishing to maintain the historical behavior of installing 1817 debug files in /boot/kernel/ can set KERN_DEBUGDIR="" in src.conf(5). 1818 181920150827: 1820 The wireless drivers had undergone changes that remove the 'parent 1821 interface' from the ifconfig -l output. The rc.d network scripts 1822 used to check presence of a parent interface in the list, so old 1823 scripts would fail to start wireless networking. Thus, etcupdate(3) 1824 or mergemaster(8) run is required after kernel update, to update your 1825 rc.d scripts in /etc. 1826 182720150827: 1828 pf no longer supports 'scrub fragment crop' or 'scrub fragment drop-ovl' 1829 These configurations are now automatically interpreted as 1830 'scrub fragment reassemble'. 1831 183220150817: 1833 Kernel-loadable modules for the random(4) device are back. To use 1834 them, the kernel must have 1835 1836 device random 1837 options RANDOM_LOADABLE 1838 1839 kldload(8) can then be used to load random_fortuna.ko 1840 or random_yarrow.ko. Please note that due to the indirect 1841 function calls that the loadable modules need to provide, 1842 the build-in variants will be slightly more efficient. 1843 1844 The random(4) kernel option RANDOM_DUMMY has been retired due to 1845 unpopularity. It was not all that useful anyway. 1846 184720150813: 1848 The WITHOUT_ELFTOOLCHAIN_TOOLS src.conf(5) knob has been retired. 1849 Control over building the ELF Tool Chain tools is now provided by 1850 the WITHOUT_TOOLCHAIN knob. 1851 185220150810: 1853 The polarity of Pulse Per Second (PPS) capture events with the 1854 uart(4) driver has been corrected. Prior to this change the PPS 1855 "assert" event corresponded to the trailing edge of a positive PPS 1856 pulse and the "clear" event was the leading edge of the next pulse. 1857 1858 As the width of a PPS pulse in a typical GPS receiver is on the 1859 order of 1 millisecond, most users will not notice any significant 1860 difference with this change. 1861 1862 Anyone who has compensated for the historical polarity reversal by 1863 configuring a negative offset equal to the pulse width will need to 1864 remove that workaround. 1865 186620150809: 1867 The default group assigned to /dev/dri entries has been changed 1868 from 'wheel' to 'video' with the id of '44'. If you want to have 1869 access to the dri devices please add yourself to the video group 1870 with: 1871 1872 # pw groupmod video -m $USER 1873 187420150806: 1875 The menu.rc and loader.rc files will now be replaced during 1876 upgrades. Please migrate local changes to menu.rc.local and 1877 loader.rc.local instead. 1878 187920150805: 1880 GNU Binutils versions of addr2line, c++filt, nm, readelf, size, 1881 strings and strip have been removed. The src.conf(5) knob 1882 WITHOUT_ELFTOOLCHAIN_TOOLS no longer provides the binutils tools. 1883 188420150728: 1885 As ZFS requires more kernel stack pages than is the default on some 1886 architectures e.g. i386, it now warns if KSTACK_PAGES is less than 1887 ZFS_MIN_KSTACK_PAGES (which is 4 at the time of writing). 1888 1889 Please consider using 'options KSTACK_PAGES=X' where X is greater 1890 than or equal to ZFS_MIN_KSTACK_PAGES i.e. 4 in such configurations. 1891 189220150706: 1893 sendmail has been updated to 8.15.2. Starting with FreeBSD 11.0 1894 and sendmail 8.15, sendmail uses uncompressed IPv6 addresses by 1895 default, i.e., they will not contain "::". For example, instead 1896 of ::1, it will be 0:0:0:0:0:0:0:1. This permits a zero subnet 1897 to have a more specific match, such as different map entries for 1898 IPv6:0:0 vs IPv6:0. This change requires that configuration 1899 data (including maps, files, classes, custom ruleset, etc.) must 1900 use the same format, so make certain such configuration data is 1901 upgrading. As a very simple check search for patterns like 1902 'IPv6:[0-9a-fA-F:]*::' and 'IPv6::'. To return to the old 1903 behavior, set the m4 option confUSE_COMPRESSED_IPV6_ADDRESSES or 1904 the cf option UseCompressedIPv6Addresses. 1905 190620150630: 1907 The default kernel entropy-processing algorithm is now 1908 Fortuna, replacing Yarrow. 1909 1910 Assuming you have 'device random' in your kernel config 1911 file, the configurations allow a kernel option to override 1912 this default. You may choose *ONE* of: 1913 1914 options RANDOM_YARROW # Legacy /dev/random algorithm. 1915 options RANDOM_DUMMY # Blocking-only driver. 1916 1917 If you have neither, you get Fortuna. For most people, 1918 read no further, Fortuna will give a /dev/random that works 1919 like it always used to, and the difference will be irrelevant. 1920 1921 If you remove 'device random', you get *NO* kernel-processed 1922 entropy at all. This may be acceptable to folks building 1923 embedded systems, but has complications. Carry on reading, 1924 and it is assumed you know what you need. 1925 1926 *PLEASE* read random(4) and random(9) if you are in the 1927 habit of tweaking kernel configs, and/or if you are a member 1928 of the embedded community, wanting specific and not-usual 1929 behaviour from your security subsystems. 1930 1931 NOTE!! If you use RANDOM_DUMMY and/or have no 'device 1932 random', you will NOT have a functioning /dev/random, and 1933 many cryptographic features will not work, including SSH. 1934 You may also find strange behaviour from the random(3) set 1935 of library functions, in particular sranddev(3), srandomdev(3) 1936 and arc4random(3). The reason for this is that the KERN_ARND 1937 sysctl only returns entropy if it thinks it has some to 1938 share, and with RANDOM_DUMMY or no 'device random' this 1939 will never happen. 1940 194120150623: 1942 An additional fix for the issue described in the 20150614 sendmail 1943 entry below has been committed in revision 284717. 1944 194520150616: 1946 FreeBSD's old make (fmake) has been removed from the system. It is 1947 available as the devel/fmake port or via pkg install fmake. 1948 194920150615: 1950 The fix for the issue described in the 20150614 sendmail entry 1951 below has been committed in revision 284436. The work 1952 around described in that entry is no longer needed unless the 1953 default setting is overridden by a confDH_PARAMETERS configuration 1954 setting of '5' or pointing to a 512 bit DH parameter file. 1955 195620150614: 1957 ALLOW_DEPRECATED_ATF_TOOLS/ATFFILE support has been removed from 1958 atf.test.mk (included from bsd.test.mk). Please upgrade devel/atf 1959 and devel/kyua to version 0.20+ and adjust any calling code to work 1960 with Kyuafile and kyua. 1961 196220150614: 1963 The import of openssl to address the FreeBSD-SA-15:10.openssl 1964 security advisory includes a change which rejects handshakes 1965 with DH parameters below 768 bits. sendmail releases prior 1966 to 8.15.2 (not yet released), defaulted to a 512 bit 1967 DH parameter setting for client connections. To work around 1968 this interoperability, sendmail can be configured to use a 1969 2048 bit DH parameter by: 1970 1971 1. Edit /etc/mail/`hostname`.mc 1972 2. If a setting for confDH_PARAMETERS does not exist or 1973 exists and is set to a string beginning with '5', 1974 replace it with '2'. 1975 3. If a setting for confDH_PARAMETERS exists and is set to 1976 a file path, create a new file with: 1977 openssl dhparam -out /path/to/file 2048 1978 4. Rebuild the .cf file: 1979 cd /etc/mail/; make; make install 1980 5. Restart sendmail: 1981 cd /etc/mail/; make restart 1982 1983 A sendmail patch is coming, at which time this file will be 1984 updated. 1985 198620150604: 1987 Generation of legacy formatted entries have been disabled by default 1988 in pwd_mkdb(8), as all base system consumers of the legacy formatted 1989 entries were converted to use the new format by default when the new, 1990 machine independent format have been added and supported since FreeBSD 1991 5.x. 1992 1993 Please see the pwd_mkdb(8) manual page for further details. 1994 199520150525: 1996 Clang and llvm have been upgraded to 3.6.1 release. Please see the 1997 20141231 entry below for information about prerequisites and upgrading, 1998 if you are not already using 3.5.0 or higher. 1999 200020150521: 2001 TI platform code switched to using vendor DTS files and this update 2002 may break existing systems running on Beaglebone, Beaglebone Black, 2003 and Pandaboard: 2004 2005 - dtb files should be regenerated/reinstalled. Filenames are the 2006 same but content is different now 2007 - GPIO addressing was changed, now each GPIO bank (32 pins per bank) 2008 has its own /dev/gpiocX device, e.g. pin 121 on /dev/gpioc0 in old 2009 addressing scheme is now pin 25 on /dev/gpioc3. 2010 - Pandaboard: /etc/ttys should be updated, serial console device is 2011 now /dev/ttyu2, not /dev/ttyu0 2012 201320150501: 2014 soelim(1) from gnu/usr.bin/groff has been replaced by usr.bin/soelim. 2015 If you need the GNU extension from groff soelim(1), install groff 2016 from package: pkg install groff, or via ports: textproc/groff. 2017 201820150423: 2019 chmod, chflags, chown and chgrp now affect symlinks in -R mode as 2020 defined in symlink(7); previously symlinks were silently ignored. 2021 202220150415: 2023 The const qualifier has been removed from iconv(3) to comply with 2024 POSIX. The ports tree is aware of this from r384038 onwards. 2025 202620150416: 2027 Libraries specified by LIBADD in Makefiles must have a corresponding 2028 DPADD_<lib> variable to ensure correct dependencies. This is now 2029 enforced in src.libnames.mk. 2030 203120150324: 2032 From legacy ata(4) driver was removed support for SATA controllers 2033 supported by more functional drivers ahci(4), siis(4) and mvs(4). 2034 Kernel modules ataahci and ataadaptec were removed completely, 2035 replaced by ahci and mvs modules respectively. 2036 203720150315: 2038 Clang, llvm and lldb have been upgraded to 3.6.0 release. Please see 2039 the 20141231 entry below for information about prerequisites and 2040 upgrading, if you are not already using 3.5.0 or higher. 2041 204220150307: 2043 The 32-bit PowerPC kernel has been changed to a position-independent 2044 executable. This can only be booted with a version of loader(8) 2045 newer than January 31, 2015, so make sure to update both world and 2046 kernel before rebooting. 2047 204820150217: 2049 If you are running a -CURRENT kernel since r273872 (Oct 30th, 2014), 2050 but before r278950, the RNG was not seeded properly. Immediately 2051 upgrade the kernel to r278950 or later and regenerate any keys (e.g. 2052 ssh keys or openssl keys) that were generated w/ a kernel from that 2053 range. This does not affect programs that directly used /dev/random 2054 or /dev/urandom. All userland uses of arc4random(3) are affected. 2055 205620150210: 2057 The autofs(4) ABI was changed in order to restore binary compatibility 2058 with 10.1-RELEASE. The automountd(8) daemon needs to be rebuilt to work 2059 with the new kernel. 2060 206120150131: 2062 The powerpc64 kernel has been changed to a position-independent 2063 executable. This can only be booted with a new version of loader(8), 2064 so make sure to update both world and kernel before rebooting. 2065 206620150118: 2067 Clang and llvm have been upgraded to 3.5.1 release. This is a bugfix 2068 only release, no new features have been added. Please see the 20141231 2069 entry below for information about prerequisites and upgrading, if you 2070 are not already using 3.5.0. 2071 207220150107: 2073 ELF tools addr2line, elfcopy (strip), nm, size, and strings are now 2074 taken from the ELF Tool Chain project rather than GNU binutils. They 2075 should be drop-in replacements, with the addition of arm64 support. 2076 The WITHOUT_ELFTOOLCHAIN_TOOLS= knob may be used to obtain the 2077 binutils tools, if necessary. See 20150805 for updated information. 2078 207920150105: 2080 The default Unbound configuration now enables remote control 2081 using a local socket. Users who have already enabled the 2082 local_unbound service should regenerate their configuration 2083 by running "service local_unbound setup" as root. 2084 208520150102: 2086 The GNU texinfo and GNU info pages have been removed. 2087 To be able to view GNU info pages please install texinfo from ports. 2088 208920141231: 2090 Clang, llvm and lldb have been upgraded to 3.5.0 release. 2091 2092 As of this release, a prerequisite for building clang, llvm and lldb is 2093 a C++11 capable compiler and C++11 standard library. This means that to 2094 be able to successfully build the cross-tools stage of buildworld, with 2095 clang as the bootstrap compiler, your system compiler or cross compiler 2096 should either be clang 3.3 or later, or gcc 4.8 or later, and your 2097 system C++ library should be libc++, or libdstdc++ from gcc 4.8 or 2098 later. 2099 2100 On any standard FreeBSD 10.x or 11.x installation, where clang and 2101 libc++ are on by default (that is, on x86 or arm), this should work out 2102 of the box. 2103 2104 On 9.x installations where clang is enabled by default, e.g. on x86 and 2105 powerpc, libc++ will not be enabled by default, so libc++ should be 2106 built (with clang) and installed first. If both clang and libc++ are 2107 missing, build clang first, then use it to build libc++. 2108 2109 On 8.x and earlier installations, upgrade to 9.x first, and then follow 2110 the instructions for 9.x above. 2111 2112 Sparc64 and mips users are unaffected, as they still use gcc 4.2.1 by 2113 default, and do not build clang. 2114 2115 Many embedded systems are resource constrained, and will not be able to 2116 build clang in a reasonable time, or in some cases at all. In those 2117 cases, cross building bootable systems on amd64 is a workaround. 2118 2119 This new version of clang introduces a number of new warnings, of which 2120 the following are most likely to appear: 2121 2122 -Wabsolute-value 2123 2124 This warns in two cases, for both C and C++: 2125 * When the code is trying to take the absolute value of an unsigned 2126 quantity, which is effectively a no-op, and almost never what was 2127 intended. The code should be fixed, if at all possible. If you are 2128 sure that the unsigned quantity can be safely cast to signed, without 2129 loss of information or undefined behavior, you can add an explicit 2130 cast, or disable the warning. 2131 2132 * When the code is trying to take an absolute value, but the called 2133 abs() variant is for the wrong type, which can lead to truncation. 2134 If you want to disable the warning instead of fixing the code, please 2135 make sure that truncation will not occur, or it might lead to unwanted 2136 side-effects. 2137 2138 -Wtautological-undefined-compare and 2139 -Wundefined-bool-conversion 2140 2141 These warn when C++ code is trying to compare 'this' against NULL, while 2142 'this' should never be NULL in well-defined C++ code. However, there is 2143 some legacy (pre C++11) code out there, which actively abuses this 2144 feature, which was less strictly defined in previous C++ versions. 2145 2146 Squid and openjdk do this, for example. The warning can be turned off 2147 for C++98 and earlier, but compiling the code in C++11 mode might result 2148 in unexpected behavior; for example, the parts of the program that are 2149 unreachable could be optimized away. 2150 215120141222: 2152 The old NFS client and server (kernel options NFSCLIENT, NFSSERVER) 2153 kernel sources have been removed. The .h files remain, since some 2154 utilities include them. This will need to be fixed later. 2155 If "mount -t oldnfs ..." is attempted, it will fail. 2156 If the "-o" option on mountd(8), nfsd(8) or nfsstat(1) is used, 2157 the utilities will report errors. 2158 215920141121: 2160 The handling of LOCAL_LIB_DIRS has been altered to skip addition of 2161 directories to top level SUBDIR variable when their parent 2162 directory is included in LOCAL_DIRS. Users with build systems with 2163 such hierarchies and without SUBDIR entries in the parent 2164 directory Makefiles should add them or add the directories to 2165 LOCAL_DIRS. 2166 216720141109: 2168 faith(4) and faithd(8) have been removed from the base system. Faith 2169 has been obsolete for a very long time. 2170 217120141104: 2172 vt(4), the new console driver, is enabled by default. It brings 2173 support for Unicode and double-width characters, as well as 2174 support for UEFI and integration with the KMS kernel video 2175 drivers. 2176 2177 You may need to update your console settings in /etc/rc.conf, 2178 most probably the keymap. During boot, /etc/rc.d/syscons will 2179 indicate what you need to do. 2180 2181 vt(4) still has issues and lacks some features compared to 2182 syscons(4). See the wiki for up-to-date information: 2183 https://wiki.freebsd.org/Newcons 2184 2185 If you want to keep using syscons(4), you can do so by adding 2186 the following line to /boot/loader.conf: 2187 kern.vty=sc 2188 218920141102: 2190 pjdfstest has been integrated into kyua as an opt-in test suite. 2191 Please see share/doc/pjdfstest/README for more details on how to 2192 execute it. 2193 219420141009: 2195 gperf has been removed from the base system for architectures 2196 that use clang. Ports that require gperf will obtain it from the 2197 devel/gperf port. 2198 219920140923: 2200 pjdfstest has been moved from tools/regression/pjdfstest to 2201 contrib/pjdfstest . 2202 220320140922: 2204 At svn r271982, The default linux compat kernel ABI has been adjusted 2205 to 2.6.18 in support of the linux-c6 compat ports infrastructure 2206 update. If you wish to continue using the linux-f10 compat ports, 2207 add compat.linux.osrelease=2.6.16 to your local sysctl.conf. Users are 2208 encouraged to update their linux-compat packages to linux-c6 during 2209 their next update cycle. 2210 221120140729: 2212 The ofwfb driver, used to provide a graphics console on PowerPC when 2213 using vt(4), no longer allows mmap() of all physical memory. This 2214 will prevent Xorg on PowerPC with some ATI graphics cards from 2215 initializing properly unless x11-servers/xorg-server is updated to 2216 1.12.4_8 or newer. 2217 221820140723: 2219 The xdev targets have been converted to using TARGET and 2220 TARGET_ARCH instead of XDEV and XDEV_ARCH. 2221 222220140719: 2223 The default unbound configuration has been modified to address 2224 issues with reverse lookups on networks that use private 2225 address ranges. If you use the local_unbound service, run 2226 "service local_unbound setup" as root to regenerate your 2227 configuration, then "service local_unbound reload" to load the 2228 new configuration. 2229 223020140709: 2231 The GNU texinfo and GNU info pages are not built and installed 2232 anymore, WITH_INFO knob has been added to allow to built and install 2233 them again. 2234 UPDATE: see 20150102 entry on texinfo's removal 2235 223620140708: 2237 The GNU readline library is now an INTERNALLIB - that is, it is 2238 statically linked into consumers (GDB and variants) in the base 2239 system, and the shared library is no longer installed. The 2240 devel/readline port is available for third party software that 2241 requires readline. 2242 224320140702: 2244 The Itanium architecture (ia64) has been removed from the list of 2245 known architectures. This is the first step in the removal of the 2246 architecture. 2247 224820140701: 2249 Commit r268115 has added NFSv4.1 server support, merged from 2250 projects/nfsv4.1-server. Since this includes changes to the 2251 internal interfaces between the NFS related modules, a full 2252 build of the kernel and modules will be necessary. 2253 __FreeBSD_version has been bumped. 2254 225520140629: 2256 The WITHOUT_VT_SUPPORT kernel config knob has been renamed 2257 WITHOUT_VT. (The other _SUPPORT knobs have a consistent meaning 2258 which differs from the behaviour controlled by this knob.) 2259 226020140619: 2261 Maximal length of the serial number in CTL was increased from 16 to 2262 64 chars, that breaks ABI. All CTL-related tools, such as ctladm 2263 and ctld, need to be rebuilt to work with a new kernel. 2264 226520140606: 2266 The libatf-c and libatf-c++ major versions were downgraded to 0 and 2267 1 respectively to match the upstream numbers. They were out of 2268 sync because, when they were originally added to FreeBSD, the 2269 upstream versions were not respected. These libraries are private 2270 and not yet built by default, so renumbering them should be a 2271 non-issue. However, unclean source trees will yield broken test 2272 programs once the operator executes "make delete-old-libs" after a 2273 "make installworld". 2274 2275 Additionally, the atf-sh binary was made private by moving it into 2276 /usr/libexec/. Already-built shell test programs will keep the 2277 path to the old binary so they will break after "make delete-old" 2278 is run. 2279 2280 If you are using WITH_TESTS=yes (not the default), wipe the object 2281 tree and rebuild from scratch to prevent spurious test failures. 2282 This is only needed once: the misnumbered libraries and misplaced 2283 binaries have been added to OptionalObsoleteFiles.inc so they will 2284 be removed during a clean upgrade. 2285 228620140512: 2287 Clang and llvm have been upgraded to 3.4.1 release. 2288 228920140508: 2290 We bogusly installed src.opts.mk in /usr/share/mk. This file should 2291 be removed to avoid issues in the future (and has been added to 2292 ObsoleteFiles.inc). 2293 229420140505: 2295 /etc/src.conf now affects only builds of the FreeBSD src tree. In the 2296 past, it affected all builds that used the bsd.*.mk files. The old 2297 behavior was a bug, but people may have relied upon it. To get this 2298 behavior back, you can .include /etc/src.conf from /etc/make.conf 2299 (which is still global and isn't changed). This also changes the 2300 behavior of incremental builds inside the tree of individual 2301 directories. Set MAKESYSPATH to ".../share/mk" to do that. 2302 Although this has survived make universe and some upgrade scenarios, 2303 other upgrade scenarios may have broken. At least one form of 2304 temporary breakage was fixed with MAKESYSPATH settings for buildworld 2305 as well... In cases where MAKESYSPATH isn't working with this 2306 setting, you'll need to set it to the full path to your tree. 2307 2308 One side effect of all this cleaning up is that bsd.compiler.mk 2309 is no longer implicitly included by bsd.own.mk. If you wish to 2310 use COMPILER_TYPE, you must now explicitly include bsd.compiler.mk 2311 as well. 2312 231320140430: 2314 The lindev device has been removed since /dev/full has been made a 2315 standard device. __FreeBSD_version has been bumped. 2316 231720140424: 2318 The knob WITHOUT_VI was added to the base system, which controls 2319 building ex(1), vi(1), etc. Older releases of FreeBSD required ex(1) 2320 in order to reorder files share/termcap and didn't build ex(1) as a 2321 build tool, so building/installing with WITH_VI is highly advised for 2322 build hosts for older releases. 2323 2324 This issue has been fixed in stable/9 and stable/10 in r277022 and 2325 r276991, respectively. 2326 232720140418: 2328 The YES_HESIOD knob has been removed. It has been obsolete for 2329 a decade. Please move to using WITH_HESIOD instead or your builds 2330 will silently lack HESIOD. 2331 233220140405: 2333 The uart(4) driver has been changed with respect to its handling 2334 of the low-level console. Previously the uart(4) driver prevented 2335 any process from changing the baudrate or the CLOCAL and HUPCL 2336 control flags. By removing the restrictions, operators can make 2337 changes to the serial console port without having to reboot. 2338 However, when getty(8) is started on the serial device that is 2339 associated with the low-level console, a misconfigured terminal 2340 line in /etc/ttys will now have a real impact. 2341 Before upgrading the kernel, make sure that /etc/ttys has the 2342 serial console device configured as 3wire without baudrate to 2343 preserve the previous behaviour. E.g: 2344 ttyu0 "/usr/libexec/getty 3wire" vt100 on secure 2345 234620140306: 2347 Support for libwrap (TCP wrappers) in rpcbind was disabled by default 2348 to improve performance. To re-enable it, if needed, run rpcbind 2349 with command line option -W. 2350 235120140226: 2352 Switched back to the GPL dtc compiler due to updates in the upstream 2353 dts files not being supported by the BSDL dtc compiler. You will need 2354 to rebuild your kernel toolchain to pick up the new compiler. Core dumps 2355 may result while building dtb files during a kernel build if you fail 2356 to do so. Set WITHOUT_GPL_DTC if you require the BSDL compiler. 2357 235820140216: 2359 Clang and llvm have been upgraded to 3.4 release. 2360 236120140216: 2362 The nve(4) driver has been removed. Please use the nfe(4) driver 2363 for NVIDIA nForce MCP Ethernet adapters instead. 2364 236520140212: 2366 An ABI incompatibility crept into the libc++ 3.4 import in r261283. 2367 This could cause certain C++ applications using shared libraries built 2368 against the previous version of libc++ to crash. The incompatibility 2369 has now been fixed, but any C++ applications or shared libraries built 2370 between r261283 and r261801 should be recompiled. 2371 237220140204: 2373 OpenSSH will now ignore errors caused by kernel lacking of Capsicum 2374 capability mode support. Please note that enabling the feature in 2375 kernel is still highly recommended. 2376 237720140131: 2378 OpenSSH is now built with sandbox support, and will use sandbox as 2379 the default privilege separation method. This requires Capsicum 2380 capability mode support in kernel. 2381 238220140128: 2383 The libelf and libdwarf libraries have been updated to newer 2384 versions from upstream. Shared library version numbers for 2385 these two libraries were bumped. Any ports or binaries 2386 requiring these two libraries should be recompiled. 2387 __FreeBSD_version is bumped to 1100006. 2388 238920140110: 2390 If a Makefile in a tests/ directory was auto-generating a Kyuafile 2391 instead of providing an explicit one, this would prevent such 2392 Makefile from providing its own Kyuafile in the future during 2393 NO_CLEAN builds. This has been fixed in the Makefiles but manual 2394 intervention is needed to clean an objdir if you use NO_CLEAN: 2395 # find /usr/obj -name Kyuafile | xargs rm -f 2396 239720131213: 2398 The behavior of gss_pseudo_random() for the krb5 mechanism 2399 has changed, for applications requesting a longer random string 2400 than produced by the underlying enctype's pseudo-random() function. 2401 In particular, the random string produced from a session key of 2402 enctype aes256-cts-hmac-sha1-96 or aes256-cts-hmac-sha1-96 will 2403 be different at the 17th octet and later, after this change. 2404 The counter used in the PRF+ construction is now encoded as a 2405 big-endian integer in accordance with RFC 4402. 2406 __FreeBSD_version is bumped to 1100004. 2407 240820131108: 2409 The WITHOUT_ATF build knob has been removed and its functionality 2410 has been subsumed into the more generic WITHOUT_TESTS. If you were 2411 using the former to disable the build of the ATF libraries, you 2412 should change your settings to use the latter. 2413 241420131025: 2415 The default version of mtree is nmtree which is obtained from 2416 NetBSD. The output is generally the same, but may vary 2417 slightly. If you found you need identical output adding 2418 "-F freebsd9" to the command line should do the trick. For the 2419 time being, the old mtree is available as fmtree. 2420 242120131014: 2422 libbsdyml has been renamed to libyaml and moved to /usr/lib/private. 2423 This will break ports-mgmt/pkg. Rebuild the port, or upgrade to pkg 2424 1.1.4_8 and verify bsdyml not linked in, before running "make 2425 delete-old-libs": 2426 # make -C /usr/ports/ports-mgmt/pkg build deinstall install clean 2427 or 2428 # pkg install pkg; ldd /usr/local/sbin/pkg | grep bsdyml 2429 243020131010: 2431 The stable/10 branch has been created in subversion from head 2432 revision r256279. 2433 2434COMMON ITEMS: 2435 2436 General Notes 2437 ------------- 2438 Sometimes, obscure build problems are the result of environment 2439 poisoning. This can happen because the make utility reads its 2440 environment when searching for values for global variables. To run 2441 your build attempts in an "environmental clean room", prefix all make 2442 commands with 'env -i '. See the env(1) manual page for more details. 2443 Occasionally a build failure will occur with "make -j" due to a race 2444 condition. If this happens try building again without -j, and please 2445 report a bug if it happens consistently. 2446 2447 When upgrading from one major version to another it is generally best to 2448 upgrade to the latest code in the currently installed branch first, then 2449 do an upgrade to the new branch. This is the best-tested upgrade path, 2450 and has the highest probability of being successful. Please try this 2451 approach if you encounter problems with a major version upgrade. Since 2452 the stable 4.x branch point, one has generally been able to upgrade from 2453 anywhere in the most recent stable branch to head / current (or even the 2454 last couple of stable branches). See the top of this file when there's 2455 an exception. 2456 2457 The update process will emit an error on an attempt to perform a build 2458 or install from a FreeBSD version below the earliest supported version. 2459 When updating from an older version the update should be performed one 2460 major release at a time, including running `make delete-old` at each 2461 step. 2462 2463 When upgrading a live system, having a root shell around before 2464 installing anything can help undo problems. Not having a root shell 2465 around can lead to problems if pam has changed too much from your 2466 starting point to allow continued authentication after the upgrade. 2467 2468 This file should be read as a log of events. When a later event changes 2469 information of a prior event, the prior event should not be deleted. 2470 Instead, a pointer to the entry with the new information should be 2471 placed in the old entry. Readers of this file should also sanity check 2472 older entries before relying on them blindly. Authors of new entries 2473 should write them with this in mind. 2474 2475 ZFS notes 2476 --------- 2477 When upgrading the boot ZFS pool to a new version, always follow 2478 these two steps: 2479 2480 1.) recompile and reinstall the ZFS boot loader and boot block 2481 (this is part of "make buildworld" and "make installworld") 2482 2483 2.) update the ZFS boot block on your boot drive 2484 2485 The following example updates the ZFS boot block on the 2486 freebsd-boot partition of a GPT partitioned drive ada0: 2487 "gpart bootcode -p /boot/gptzfsboot -i $N ada0" 2488 The value $N will typically be 1 (if booting from BIOS) or 2 (if 2489 booting from EFI). 2490 2491 Non-boot pools do not need these updates. 2492 2493 To build a kernel 2494 ----------------- 2495 If you are updating from a prior version of FreeBSD (even one just 2496 a few days old), you should follow this procedure. It is the most 2497 failsafe as it uses a /usr/obj tree with a fresh mini-buildworld, 2498 2499 make kernel-toolchain 2500 make -DALWAYS_CHECK_MAKE buildkernel KERNCONF=YOUR_KERNEL_HERE 2501 make -DALWAYS_CHECK_MAKE installkernel KERNCONF=YOUR_KERNEL_HERE 2502 2503 To test a kernel once 2504 --------------------- 2505 If you just want to boot a kernel once (because you are not sure 2506 if it works, or if you want to boot a known bad kernel to provide 2507 debugging information) run 2508 make installkernel KERNCONF=YOUR_KERNEL_HERE KODIR=/boot/testkernel 2509 nextboot -k testkernel 2510 2511 To rebuild everything and install it on the current system. 2512 ----------------------------------------------------------- 2513 # Note: sometimes if you are running current you gotta do more than 2514 # is listed here if you are upgrading from a really old current. 2515 2516 <make sure you have good level 0 dumps> 2517 make buildworld 2518 make buildkernel KERNCONF=YOUR_KERNEL_HERE 2519 make installkernel KERNCONF=YOUR_KERNEL_HERE 2520 [1] 2521 <reboot in single user> [3] 2522 etcupdate -p [5] 2523 make installworld 2524 etcupdate -B [4] 2525 make delete-old [6] 2526 <reboot> 2527 2528 To cross-install current onto a separate partition 2529 -------------------------------------------------- 2530 # In this approach we use a separate partition to hold 2531 # current's root, 'usr', and 'var' directories. A partition 2532 # holding "/", "/usr" and "/var" should be about 2GB in 2533 # size. 2534 2535 <make sure you have good level 0 dumps> 2536 <boot into -stable> 2537 make buildworld 2538 make buildkernel KERNCONF=YOUR_KERNEL_HERE 2539 <maybe newfs current's root partition> 2540 <mount current's root partition on directory ${CURRENT_ROOT}> 2541 make installworld DESTDIR=${CURRENT_ROOT} -DDB_FROM_SRC 2542 make distribution DESTDIR=${CURRENT_ROOT} # if newfs'd 2543 make installkernel KERNCONF=YOUR_KERNEL_HERE DESTDIR=${CURRENT_ROOT} 2544 cp /etc/fstab ${CURRENT_ROOT}/etc/fstab # if newfs'd 2545 <edit ${CURRENT_ROOT}/etc/fstab to mount "/" from the correct partition> 2546 <reboot into current> 2547 <do a "native" rebuild/install as described in the previous section> 2548 <maybe install compatibility libraries from ports/misc/compat*> 2549 <reboot> 2550 2551 2552 To upgrade in-place from stable to current 2553 ---------------------------------------------- 2554 <make sure you have good level 0 dumps> 2555 make buildworld [9] 2556 make buildkernel KERNCONF=YOUR_KERNEL_HERE [8] 2557 make installkernel KERNCONF=YOUR_KERNEL_HERE 2558 [1] 2559 <reboot in single user> [3] 2560 etcupdate -p [5] 2561 make installworld 2562 etcupdate -B [4] 2563 make delete-old [6] 2564 <reboot> 2565 2566 Make sure that you've read the UPDATING file to understand the 2567 tweaks to various things you need. At this point in the life 2568 cycle of current, things change often and you are on your own 2569 to cope. The defaults can also change, so please read ALL of 2570 the UPDATING entries. 2571 2572 Also, if you are tracking -current, you must be subscribed to 2573 freebsd-current@freebsd.org. Make sure that before you update 2574 your sources that you have read and understood all the recent 2575 messages there. If in doubt, please track -stable which has 2576 much fewer pitfalls. 2577 2578 [1] If you have third party modules, such as vmware, you should disable 2579 them at this point so they don't crash your system on 2580 reboot. Alternatively, you should rebuild all the modules you have in 2581 your system and install them as well. If you are running -current, you 2582 should seriously consider placing all sources to all the modules for 2583 your system (or symlinks to them) in /usr/local/sys/modules so this 2584 happens automatically. If all your modules come from ports, then adding 2585 the port origin directories to PORTS_MODULES instead is also automatic 2586 and effective, eg: 2587 PORTS_MODULES+=x11/nvidia-driver 2588 2589 [3] From the bootblocks, boot -s, and then do 2590 fsck -p 2591 mount -u / 2592 mount -a 2593 sh /etc/rc.d/zfs start # mount zfs filesystem, if needed 2594 cd src # full path to source 2595 adjkerntz -i # if CMOS is wall time 2596 Also, when doing a major release upgrade, it is required that you boot 2597 into single user mode to do the installworld. 2598 2599 [4] Note: This step is non-optional. Failure to do this step 2600 can result in a significant reduction in the functionality of the 2601 system. Attempting to do it by hand is not recommended and those 2602 that pursue this avenue should read this file carefully, as well 2603 as the archives of freebsd-current and freebsd-hackers mailing lists 2604 for potential gotchas. See etcupdate(8) for more information. 2605 2606 [5] Usually this step is a no-op. However, from time to time 2607 you may need to do this if you get unknown user in the following 2608 step. 2609 2610 [6] This only deletes old files and directories. Old libraries 2611 can be deleted by "make delete-old-libs", but you have to make 2612 sure that no program is using those libraries anymore. 2613 2614 [8] The new kernel must be able to run existing binaries used by an 2615 installworld. When upgrading across major versions, the new kernel's 2616 configuration must include the correct COMPAT_FREEBSD<n> option for 2617 existing binaries (e.g. COMPAT_FREEBSD11 to run 11.x binaries). Failure 2618 to do so may leave you with a system that is hard to boot to recover. A 2619 GENERIC kernel will include suitable compatibility options to run 2620 binaries from older branches. Note that the ability to run binaries 2621 from unsupported branches is not guaranteed. 2622 2623 Make sure that you merge any new devices from GENERIC since the 2624 last time you updated your kernel config file. Options also 2625 change over time, so you may need to adjust your custom kernels 2626 for these as well. 2627 2628 [9] If CPUTYPE is defined in your /etc/make.conf, make sure to use the 2629 "?=" instead of the "=" assignment operator, so that buildworld can 2630 override the CPUTYPE if it needs to. 2631 2632 MAKEOBJDIRPREFIX must be defined in an environment variable, and 2633 not on the command line, or in /etc/make.conf. buildworld will 2634 warn if it is improperly defined. 2635FORMAT: 2636 2637This file contains a list, in reverse chronological order, of major 2638breakages in tracking -current. It is not guaranteed to be a complete 2639list of such breakages, and only contains entries since September 23, 2011. 2640If you need to see UPDATING entries from before that date, you will need 2641to fetch an UPDATING file from an older FreeBSD release. 2642 2643Copyright information: 2644 2645Copyright 1998-2009 M.
