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 3020221026: 31 Some programs have been moved into separate packages. It is recommended 32 for pkgbase users to do: 33 34 pkg install FreeBSD-dhclient FreeBSD-geom FreeBSD-resolvconf \ 35 FreeBSD-devd FreeBSD-devmatch 36 37 after upgrading to restore all the component that were previously 38 installed. 39 4020220610: 41 LinuxKPI pm.h changes require an update to the latest drm-kmod version 42 before re-compiling to avoid errors. 43 4420211230: 45 The macros provided for the manipulation of CPU sets (e.g. CPU_AND) 46 have been modified to take 2 source arguments instead of only 1. 47 Externally maintained sources that use these macros will have to 48 be adapted. The FreeBSD version has been bumped to 1400046 to 49 reflect this change. 50 5120211214: 52 A number of the kernel include files are able to be included by 53 themselves. A test has been added to buildworld to enforce this. 54 5520211209: 56 Remove mips as a recognized target. This starts the decommissioning of 57 mips support in FreeBSD. mips related items will be removed wholesale in 58 the coming days and weeks. 59 60 This broke the NO_CLEAN build for some people. Either do a clean build 61 or touch 62 lib/clang/include/llvm/Config/Targets.def 63 lib/clang/include/llvm/Config/AsmParsers.def 64 lib/clang/include/llvm/Config/Disassemblers.def 65 lib/clang/include/llvm/Config/AsmPrinters.def 66 before the build to force everything to rebuild that needs to. 67 6820211202: 69 Unbound support for RFC8375: The special-use domain 'home.arpa' is 70 by default blocked. To unblock it use a local-zone nodefault 71 statement in unbound.conf: 72 local-zone: "home.arpa." nodefault 73 74 Or use another type of local-zone to override with your choice. 75 76 The reason for this is discussed in Section 6.1 of RFC8375: 77 Because 'home.arpa.' is not globally scoped and cannot be secured 78 using DNSSEC based on the root domain's trust anchor, there is no way 79 to tell, using a standard DNS query, in which homenet scope an answer 80 belongs. Consequently, users may experience surprising results with 81 such names when roaming to different homenets. 82 8320211110: 84 Commit b8d60729deef changed the TCP congestion control framework so 85 that any of the included congestion control modules could be 86 the single module built into the kernel. Previously newreno 87 was automatically built in through direct reference. As of 88 this commit you are required to declare at least one congestion 89 control module (e.g. 'options CC_NEWRENO') and to also declare a 90 default using the CC_DEFAULT option (e.g. options CC_DEFAULT="newreno\"). 91 The GENERIC configuration includes CC_NEWRENO and defines newreno 92 as the default. If no congestion control option is built into the 93 kernel and you are including networking, the kernel compile will 94 fail. Also if no default is declared the kernel compile will fail. 95 9620211118: 97 Mips has been removed from universe builds. It will be removed from the 98 tree shortly. 99 10020211106: 101 Commit f0c9847a6c47 changed the arguments for VOP_ALLOCATE. 102 The NFS modules must be rebuilt from sources and any out 103 of tree file systems that implement their own VOP_ALLOCATE 104 may need to be modified. 105 10620211022: 107 The synchronous PPP kernel driver sppp(4) has been removed. 108 The cp(4) and ce(4) drivers are now always compiled with netgraph(4) 109 support, formerly enabled by NETGRAPH_CRONYX option. 110 11120211020: 112 sh(1) is now the default shell for the root user. To force root to use 113 the csh shell, please run the following command as root: 114 115 # chsh -s csh 116 11720211004: 118 Ncurses distribution has been split between libtinfow and libncurses 119 with libncurses.so becoming a linker (ld) script to seamlessly link 120 to libtinfow as needed. Bump _FreeBSD_version to 1400035 to reflect 121 this change. 122 12320210923: 124 As of commit 8160a0f62be6, the dummynet module no longer depends on the 125 ipfw module. Dummynet can now be used by pf as well as ipfw. As such 126 users who relied on this dependency may need to include ipfw in the 127 list of modules to load on their systems. 128 12920210922: 130 As of commit 903873ce1560, the mixer(8) utility has got a slightly 131 new syntax. Please refer to the mixer(8) manual page for more 132 information. The old mixer utility can be installed from ports: 133 audio/freebsd-13-mixer 134 13520210911: 136 As of commit 55089ef4f8bb, the global variable nfs_maxcopyrange has 137 been deleted from the nfscommon.ko. As such, nfsd.ko must be built 138 from up to date sources to avoid an undefined reference when 139 being loaded. 140 14120210817: 142 As of commit 62ca9fc1ad56 OpenSSL no longer enables kernel TLS 143 by default. Users can enable kernel TLS via the "KTLS" SSL 144 option. This can be enabled globally by using a custom 145 OpenSSL config file via OPENSSL_CONF or via an 146 application-specific configuration option for applications 147 which permit setting SSL options via SSL_CONF_cmd(3). 148 14920210811: 150 Commit 3ad1e1c1ce20 changed the internal KAPI between the NFS 151 modules. Therefore, all need to be rebuilt from sources. 152 15320210730: 154 Commit b69019c14cd8 removes pf's DIOCGETSTATESNV ioctl. 155 As of be70c7a50d32 it is no longer used by userspace, but it does mean 156 users may not be able to enumerate pf states if they update the kernel 157 past b69019c14cd8 without first updating userspace past be70c7a50d32. 158 15920210729: 160 As of commit 01ad0c007964 if_bridge member interfaces can no longer 161 change their MTU. Changing the MTU of the bridge itself will change the 162 MTU on all member interfaces instead. 163 16420210716: 165 Commit ee29e6f31111 changed the internal KAPI between the nfscommon 166 and nfsd modules. Therefore, both need to be rebuilt from sources. 167 Bump __FreeBSD_version to 1400026 for this KAPI change. 168 16920210715: 170 The 20210707 awk update brought in a change in behavior. This has 171 been corrected as of d4d252c49976. Between these dates, if you 172 installed a new awk binary, you may not be able to build a new 173 kernel because the change in behavior affected the genoffset 174 script used to build the kernel. If you did update, the fix is 175 to update your sources past the above hash and do 176 % cd usr.bin/awk 177 % make clean all 178 % sudo -E make install 179 to enable building kernels again. 180 18120210708: 182 Commit 1e0a518d6548 changed the internal KAPI between the NFS 183 modules. They all need to be rebuilt from sources. I did not 184 bump __FreeBSD_version, since it was bumped recently. 185 18620210707: 187 awk has been updated to the latest one-true-awk version 20210215. 188 This contains a number of minor bug fixes. 189 19020210624: 191 The NFSv4 client now uses the highest minor version of NFSv4 192 supported by the NFSv4 server by default instead of minor version 0, 193 for NFSv4 mounts. 194 The "minorversion" mount option may be used to override this default. 195 19620210618: 197 Bump __FreeBSD_version to 1400024 for LinuxKPI changes. 198 Most notably netdev.h can change now as the (last) dependencies 199 (mlx4/ofed) are now using struct ifnet directly, but also for PCI 200 additions and others. 201 20220210618: 203 The directory "blacklisted" under /usr/share/certs/ has been 204 renamed to "untrusted". 205 20620210611: 207 svnlite has been removed from base. Should you need svn for any reason 208 please install the svn package or port. 209 21020210611: 211 Commit e1a907a25cfa changed the internal KAPI between the krpc 212 and nfsserver. As such, both modules must be rebuilt from 213 sources. Bump __FreeBSD_version to 1400022. 214 21520210610: 216 The an(4) driver has been removed from FreeBSD. 217 21820210608: 219 The vendor/openzfs branch was renamed to vendor/openzfs/legacy to 220 start tracking OpenZFS upstream more closely. Please see 221https://lists.freebsd.org/archives/freebsd-current/2021-June/000153.html 222 for details on how to correct any errors that might result. The 223 short version is that you need to remove the old branch locally: 224 git update-ref -d refs/remotes/freebsd/vendor/openzfs 225 (assuming your upstream origin is named 'freebsd'). 226 22720210525: 228 Commits 17accc08ae15 and de102f870501 add new files to LinuxKPI 229 which break drm-kmod. In addition various other additions where 230 committed. Bump __FreeBSD_version to 1400015 to be able to 231 detect this. 232 23320210513: 234 Commit ca179c4d74f2 changed the package in which the OpenSSL 235 libraries and utilities are packaged. 236 It is recommended for pkgbase user to do: 237 pkg install -f FreeBSD-openssl 238 before pkg upgrade otherwise some dependencies might not be met 239 and pkg will stop working as libssl will not be present anymore 240 on the system. 241 24220210426: 243 Commit 875977314881 changed the internal KAPI between 244 the nfsd and nfscommon modules. As such these modules 245 need to be rebuilt from sources. 246 Without this patch in your NFSv4.1/4.2 server, enabling 247 delegations by setting vfs.nfsd.issue_delegations non-zero 248 is not recommended. 249 25020210411: 251 Commit 7763814fc9c2 changed the internal KAPI between 252 the krpc and NFS. As such, the krpc, nfscommon and 253 nfscl modules must all be rebuilt from sources. 254 Without this patch, NFSv4.1/4.2 mounts should not 255 be done with the nfscbd(8) daemon running, to avoid 256 needing a working back channel for server->client RPCs. 257 25820210330: 259 Commit 01ae8969a9ee fixed the NFSv4.1/4.2 server so that it 260 handles binding of the back channel as required by RFC5661. 261 Until this patch is in your server, avoid use of the "nconnects" 262 mount option for Linux NFSv4.1/4.2 mounts. 263 26420210225: 265 For 64-bit architectures the base system is now built with Position 266 Independent Executable (PIE) support enabled by default. It may be 267 disabled using the WITHOUT_PIE knob. A clean build is required. 268 26920210128: 270 Various LinuxKPI functionality was added which conflicts with DRM. 271 Please update your drm-kmod port to after the __FreeBSD_version 1400003 272 update. 273 27420210108: 275 PC Card attachments for all devices have been removed. In the case of 276 wi and cmx, the entire drivers were removed because they were only 277 PC Card devices. FreeBSD_version 1300134 should be used for this 278 since it was bumped so recently. 279 28020210107: 281 Transport-independent parts of HID support have been split off the USB 282 code in to separate subsystem. Kernel configs which include one of 283 ums, ukbd, uhid, atp, wsp, wmt, uaudio, ugold or ucycom drivers should 284 be updated with adding of "device hid" line. 285 28620210105: 287 ncurses installation has been modified to only keep the widechar 288 enabled version. Incremental build is broken for that change, so it 289 requires a clean build. 290 29120201223: 292 The FreeBSD project has migrated from Subversion to Git. Temporary 293 instructions can be found at 294 https://github.com/bsdimp/freebsd-git-docs/blob/main/src-cvt.md 295 and other documents in that repo. 296 29720201216: 298 The services database has been updated to cover more of the basic 299 services expected in a modern system. The database is big enough 300 that it will cause issues in mergemaster in Releases previous to 301 12.2 and 11.3, or in very old current systems from before r358154. 302 30320201215: 304 Obsolete in-tree GDB 6.1.1 has been removed. GDB (including kgdb) 305 may be installed from ports or packages. 306 30720201124: 308 ping6 has been merged into ping. It can now be called as "ping -6". 309 See ping(8) for details. 310 31120201108: 312 Default value of net.add_addr_allfibs has been changed to 0. 313 If you have multi-fib configuration and rely on existence of all 314 interface routes in every fib, you need to set the above sysctl to 1. 315 31620201030: 317 The internal pre-processor in the calendar(1) program has been 318 extended to support more C pre-processor commands (e.g. #ifdef, #else, 319 and #undef) and to detect unbalanced conditional statements. 320 Error messages have been extended to include the filename and line 321 number if processing stops to help fixing malformed data files. 322 32320201026: 324 All the data files for the calendar(1) program, except calendar.freebsd, 325 have been moved to the deskutils/calendar-data port, much like the 326 jewish calendar entries were moved to deskutils/hebcal years ago. After 327 make delete-old-files, you need to install it to retain full 328 functionality. calendar(1) will issue a reminder for files it can't 329 find. 330 33120200923: 332 LINT files are no longer generated. We now include the relevant NOTES 333 files. Note: This may cause conflicts with updating in some cases. 334 find sys -name LINT\* -delete 335 is suggested across this commit to remove the generated LINT files. 336 337 If you have tried to update with generated files there, the svn 338 command you want to un-auger the tree is 339 cd sys/amd64/conf 340 svn revert -R . 341 and then do the above find from the top level. Substitute 'amd64' 342 above with where the error message indicates a conflict. 343 34420200824: 345 OpenZFS support has been integrated. Do not upgrade root pools until 346 the loader is updated to support zstd. Furthermore, we caution against 347 'zpool upgrade' for the next few weeks. The change should be transparent 348 unless you want to use new features. 349 350 Not all "NO_CLEAN" build scenarios work across these changes. Many 351 scenarios have been tested and fixed, but rebuilding kernels without 352 rebuilding world may fail. 353 354 The ZFS cache file has moved from /boot to /etc to match the OpenZFS 355 upstream default. A fallback to /boot has been added for mountroot. 356 357 Pool auto import behavior at boot has been moved from the kernel module 358 to an explicit "zpool import -a" in one of the rc scripts enabled by 359 zfs_enable=YES. This means your non-root zpools won't auto import until 360 you upgrade your /etc/rc.d files. 361 36220200824: 363 The resume code now notifies devd with the 'kernel' system 364 rather than the old 'kern' subsystem to be consistent with 365 other use. The old notification will be created as well, but 366 will be removed prior to FreeBSD 14.0. 367 36820200821: 369 r362275 changed the internal API between the kernel RPC and the 370 NFS modules. As such, all the modules must be recompiled from 371 sources. 372 37320200817: 374 r364330 modified the internal API used between the NFS modules. 375 As such, all the NFS modules must be re-compiled from sources. 376 37720200816: 378 Clang, llvm, lld, lldb, compiler-rt, libc++, libunwind and openmp have 379 been upgraded to 11.0.0. Please see the 20141231 entry below for 380 information about prerequisites and upgrading, if you are not already 381 using clang 3.5.0 or higher. 382 38320200810: 384 r364092 modified the internal ABI used between the kernel NFS 385 modules. As such, all of these modules need to be rebuilt 386 from sources, so a version bump was done. 387 38820200807: 389 Makefile.inc has been updated to work around the issue documented in 390 20200729. It was a case where the optimization of using symbolic links 391 to point to binaries created a situation where we'd run new binaries 392 with old libraries starting midway through the installworld process. 393 39420200729: 395 r363679 has redefined some undefined behavior in regcomp(3); notably, 396 extraneous escapes of most ordinary characters will no longer be 397 accepted. An exp-run has identified all of the problems with this in 398 ports, but other non-ports software may need extra escapes removed to 399 continue to function. 400 401 Because of this change, installworld may encounter the following error 402 from rtld: Undefined symbol "regcomp@FBSD_1.6" -- It is imperative that 403 you do not halt installworld. Instead, let it run to completion (whether 404 successful or not) and run installworld once more. 405 40620200627: 407 A new implementation of bc and dc has been imported in r362681. This 408 implementation corrects non-conformant behavior of the previous bc 409 and adds GNU bc compatible options. It offers a number of extensions, 410 is much faster on large values, and has support for message catalogs 411 (a number of languages are already supported, contributions of further 412 languages welcome). The option WITHOUT_GH_BC can be used to build the 413 world with the previous versions of bc and dc. 414 41520200625: 416 r362639 changed the internal API used between the NFS kernel modules. 417 As such, they all need to be rebuilt from sources. 418 41920200613: 420 r362158 changed the arguments for VFS_CHECKEXP(). As such, any 421 out of tree file systems need to be modified and rebuilt. 422 Also, any file systems that are modules must be rebuilt. 423 42420200604: 425 read(2) of a directory fd is now rejected by default. root may 426 re-enable it for system root only on non-ZFS filesystems with the 427 security.bsd.allow_read_dir sysctl(8) MIB if 428 security.bsd.suser_enabled=1. 429 430 It may be advised to setup aliases for grep to default to `-d skip` if 431 commonly non-recursively grepping a list that includes directories and 432 the potential for the resulting stderr output is not tolerable. Example 433 aliases are now installed, commented out, in /root/.cshrc and 434 /root/.shrc. 435 43620200523: 437 Clang, llvm, lld, lldb, compiler-rt, libc++, libunwind and openmp have 438 been upgraded to 10.0.1. Please see the 20141231 entry below for 439 information about prerequisites and upgrading, if you are not already 440 using clang 3.5.0 or higher. 441 44220200512: 443 Support for obsolete compilers has been removed from the build system. 444 Clang 6 and GCC 6.4 are the minimum supported versions. 445 44620200424: 447 closefrom(2) has been moved under COMPAT12, and replaced in libc with a 448 stub that calls close_range(2). If using a custom kernel configuration, 449 you may want to ensure that the COMPAT_FREEBSD12 option is included, as 450 a slightly older -CURRENT userland and older FreeBSD userlands may not 451 be functional without closefrom(2). 452 45320200414: 454 Upstream DTS from Linux 5.6 was merged and they now have the SID 455 and THS (Secure ID controller and THermal Sensor) node present. 456 The DTB overlays have now been removed from the tree for the H3/H5 and 457 A64 SoCs and the aw_sid and aw_thermal driver have been updated to 458 deal with upstream DTS. If you are using those overlays you need to 459 remove them from loader.conf and update the DTBs on the FAT partition. 460 46120200310: 462 Clang, llvm, lld, lldb, compiler-rt, libc++, libunwind and openmp have 463 been upgraded to 10.0.0. Please see the 20141231 entry below for 464 information about prerequisites and upgrading, if you are not already 465 using clang 3.5.0 or higher. 466 46720200309: 468 The amd(8) automount daemon has been removed from the source tree. 469 As of FreeBSD 10.1 autofs(5) is the preferred tool for automounting. 470 amd is still available in the sysutils/am-utils port. 471 47220200301: 473 Removed brooktree driver (bktr.4) from the tree. 474 47520200229: 476 The WITH_GPL_DTC option has been removed. The BSD-licenced device tree 477 compiler in usr.bin/dtc is used on all architectures which use dtc, and 478 the GPL dtc is available (if needed) from the sysutils/dtc port. 479 48020200229: 481 The WITHOUT_LLVM_LIBUNWIND option has been removed. LLVM's libunwind 482 is used by all supported CPU architectures. 483 48420200229: 485 GCC 4.2.1 has been removed from the tree. The WITH_GCC, 486 WITH_GCC_BOOTSTRAP, and WITH_GNUCXX options are no longer available. 487 Users who wish to build FreeBSD with GCC must use the external toolchain 488 ports or packages. 489 49020200220: 491 ncurses has been updated to a newer version (6.2-20200215). Given the ABI 492 has changed, users will have to rebuild all the ports that are linked to 493 ncurses. 494 49520200217: 496 The size of struct vnet and the magic cookie have changed. 497 Users need to recompile libkvm and all modules using VIMAGE 498 together with their new kernel. 499 50020200212: 501 Defining the long deprecated NO_CTF, NO_DEBUG_FILES, NO_INSTALLLIB, 502 NO_MAN, NO_PROFILE, and NO_WARNS variables is now an error. Update 503 your Makefiles and scripts to define MK_<var>=no instead as required. 504 505 One exception to this is that program or library Makefiles should 506 define MAN to empty rather than setting MK_MAN=no. 507 50820200108: 509 Clang/LLVM is now the default compiler and LLD the default 510 linker for riscv64. 511 51220200107: 513 make universe no longer uses GCC 4.2.1 on any architectures. 514 Architectures not supported by in-tree Clang/LLVM require an 515 external toolchain package. 516 51720200104: 518 GCC 4.2.1 is now not built by default, as part of the GCC 4.2.1 519 retirement plan. Specifically, the GCC, GCC_BOOTSTRAP, and GNUCXX 520 options default to off for all supported CPU architectures. As a 521 short-term transition aid they may be enabled via WITH_* options. 522 GCC 4.2.1 is expected to be removed from the tree on 2020-03-31. 523 52420200102: 525 Support for armv5 has been disconnected and is being removed. The 526 machine combination MACHINE=arm MACHINE_ARCH=arm is no longer valid. 527 You must now use a MACHINE_ARCH of armv6 or armv7. The default 528 MACHINE_ARCH for MACHINE=arm is now armv7. 529 53020191226: 531 Clang/LLVM is now the default compiler for all powerpc architectures. 532 LLD is now the default linker for powerpc64. The change for powerpc64 533 also includes a change to the ELFv2 ABI, incompatible with the existing 534 ABI. 535 53620191226: 537 Kernel-loadable random(4) modules are no longer unloadable. 538 53920191222: 540 Clang, llvm, lld, lldb, compiler-rt, libc++, libunwind and openmp have 541 been upgraded to 9.0.1. Please see the 20141231 entry below for 542 information about prerequisites and upgrading, if you are not already 543 using clang 3.5.0 or higher. 544 54520191212: 546 r355677 has modified the internal interface used between the 547 NFS modules in the kernel. As such, they must all be upgraded 548 simultaneously. I will do a version bump for this. 549 55020191205: 551 The root certificates of the Mozilla CA Certificate Store have been 552 imported into the base system and can be managed with the certctl(8) 553 utility. If you have installed the security/ca_root_nss port or package 554 with the ETCSYMLINK option (the default), be advised that there may be 555 differences between those included in the port and those included in 556 base due to differences in nss branch used as well as general update 557 frequency. Note also that certctl(8) cannot manage certs in the 558 format used by the security/ca_root_nss port. 559 56020191120: 561 The amd(8) automount daemon has been disabled by default, and will be 562 removed in the future. As of FreeBSD 10.1 the autofs(5) is available 563 for automounting. 564 56520191107: 566 The nctgpio and wbwd drivers have been moved to the superio bus. 567 If you have one of these drivers in a kernel configuration, then 568 you should add device superio to it. If you use one of these drivers 569 as a module and you compile a custom set of modules, then you should 570 add superio to the set. 571 57220191021: 573 KPIs for network drivers to access interface addresses have changed. 574 Users need to recompile NIC driver modules together with kernel. 575 57620191021: 577 The net.link.tap.user_open sysctl no longer prevents user opening of 578 already created /dev/tapNN devices. Access is still controlled by 579 node permissions, just like tun devices. The net.link.tap.user_open 580 sysctl is now used only to allow users to perform devfs cloning of 581 tap devices, and the subsequent open may not succeed if the user is not 582 in the appropriate group. This sysctl may be deprecated/removed 583 completely in the future. 584 58520191009: 586 mips, powerpc, and sparc64 are no longer built as part of 587 universe / tinderbox unless MAKE_OBSOLETE_GCC is defined. If 588 not defined, mips, powerpc, and sparc64 builds will look for 589 the xtoolchain binaries and if installed use them for universe 590 builds. As llvm 9.0 becomes vetted for these architectures, they 591 will be removed from the list. 592 59320191009: 594 Clang, llvm, lld, lldb, compiler-rt, libc++, libunwind and openmp have 595 been upgraded to 9.0.0. Please see the 20141231 entry below for 596 information about prerequisites and upgrading, if you are not already 597 using clang 3.5.0 or higher. 598 59920191003: 600 The hpt27xx, hptmv, hptnr, and hptrr drivers have been removed from 601 GENERIC. They are available as modules and can be loaded by adding 602 to /boot/loader.conf hpt27xx_load="YES", hptmv_load="YES", 603 hptnr_load="YES", or hptrr_load="YES", respectively. 604 60520190913: 606 ntpd no longer by default locks its pages in memory, allowing them 607 to be paged out by the kernel. Use rlimit memlock to restore 608 historic BSD behaviour. For example, add "rlimit memlock 32" 609 to ntp.conf to lock up to 32 MB of ntpd address space in memory. 610 61120190823: 612 Several of ping6's options have been renamed for better consistency 613 with ping. If you use any of -ARWXaghmrtwx, you must update your 614 scripts. See ping6(8) for details. 615 61620190727: 617 The vfs.fusefs.sync_unmount and vfs.fusefs.init_backgrounded sysctls 618 and the "-o sync_unmount" and "-o init_backgrounded" mount options have 619 been removed from mount_fusefs(8). You can safely remove them from 620 your scripts, because they had no effect. 621 622 The vfs.fusefs.fix_broken_io, vfs.fusefs.sync_resize, 623 vfs.fusefs.refresh_size, vfs.fusefs.mmap_enable, 624 vfs.fusefs.reclaim_revoked, and vfs.fusefs.data_cache_invalidate 625 sysctls have been removed. If you felt the need to set any of them to 626 a non-default value, please tell asomers@FreeBSD.org why. 627 62820190713: 629 Default permissions on the /var/account/acct file (and copies of it 630 rotated by periodic daily scripts) are changed from 0644 to 0640 631 because the file contains sensitive information that should not be 632 world-readable. If the /var/account directory must be created by 633 rc.d/accounting, the mode used is now 0750. Admins who use the 634 accounting feature are encouraged to change the mode of an existing 635 /var/account directory to 0750 or 0700. 636 63720190620: 638 Entropy collection and the /dev/random device are no longer optional 639 components. The "device random" option has been removed. 640 Implementations of distilling algorithms can still be made loadable 641 with "options RANDOM_LOADABLE" (e.g., random_fortuna.ko). 642 64320190612: 644 Clang, llvm, lld, lldb, compiler-rt, libc++, libunwind and openmp have 645 been upgraded to 8.0.1. Please see the 20141231 entry below for 646 information about prerequisites and upgrading, if you are not already 647 using clang 3.5.0 or higher. 648 64920190608: 650 A fix was applied to i386 kernel modules to avoid panics with 651 dpcpu or vnet. Users need to recompile i386 kernel modules 652 having pcpu or vnet sections or they will refuse to load. 653 65420190513: 655 User-wired pages now have their own counter, 656 vm.stats.vm.v_user_wire_count. The vm.max_wired sysctl was renamed 657 to vm.max_user_wired and changed from an unsigned int to an unsigned 658 long. bhyve VMs wired with the -S are now subject to the user 659 wiring limit; the vm.max_user_wired sysctl may need to be tuned to 660 avoid running into the limit. 661 66220190507: 663 The IPSEC option has been removed from GENERIC. Users requiring 664 ipsec(4) must now load the ipsec(4) kernel module. 665 66620190507: 667 The tap(4) driver has been folded into tun(4), and the module has been 668 renamed to tuntap. You should update any kld_list="if_tap" or 669 kld_list="if_tun" entries in /etc/rc.conf, if_tap_load="YES" or 670 if_tun_load="YES" entries in /boot/loader.conf to load the if_tuntap 671 module instead, and "device tap" or "device tun" entries in kernel 672 config files to select the tuntap device instead. 673 67420190418: 675 The following knobs have been added related to tradeoffs between 676 safe use of the random device and availability in the absence of 677 entropy: 678 679 kern.random.initial_seeding.bypass_before_seeding: tunable; set 680 non-zero to bypass the random device prior to seeding, or zero to 681 block random requests until the random device is initially seeded. 682 For now, set to 1 (unsafe) by default to restore pre-r346250 boot 683 availability properties. 684 685 kern.random.initial_seeding.read_random_bypassed_before_seeding: 686 read-only diagnostic sysctl that is set when bypass is enabled and 687 read_random(9) is bypassed, to enable programmatic handling of this 688 initial condition, if desired. 689 690 kern.random.initial_seeding.arc4random_bypassed_before_seeding: 691 Similar to the above, but for arc4random(9) initial seeding. 692 693 kern.random.initial_seeding.disable_bypass_warnings: tunable; set 694 non-zero to disable warnings in dmesg when the same conditions are 695 met as for the diagnostic sysctls above. Defaults to zero, i.e., 696 produce warnings in dmesg when the conditions are met. 697 69820190416: 699 The loadable random module KPI has changed; the random_infra_init() 700 routine now requires a 3rd function pointer for a bool (*)(void) 701 method that returns true if the random device is seeded (and 702 therefore unblocked). 703 70420190404: 705 r345895 reverts r320698. This implies that an nfsuserd(8) daemon 706 built from head sources between r320757 (July 6, 2017) and 707 r338192 (Aug. 22, 2018) will not work unless the "-use-udpsock" 708 is added to the command line. 709 nfsuserd daemons built from head sources that are post-r338192 are 710 not affected and should continue to work. 711 71220190320: 713 The fuse(4) module has been renamed to fusefs(4) for consistency with 714 other filesystems. You should update any kld_load="fuse" entries in 715 /etc/rc.conf, fuse_load="YES" entries in /boot/loader.conf, and 716 "options FUSE" entries in kernel config files. 717 71820190304: 719 Clang, llvm, lld, lldb, compiler-rt and libc++ have been upgraded to 720 8.0.0. Please see the 20141231 entry below for information about 721 prerequisites and upgrading, if you are not already using clang 3.5.0 722 or higher. 723 72420190226: 725 geom_uzip(4) depends on the new module xz. If geom_uzip is statically 726 compiled into your custom kernel, add 'device xz' statement to the 727 kernel config. 728 72920190219: 730 drm and drm2 have been removed from the tree. Please see 731 https://wiki.freebsd.org/Graphics for the latest information on 732 migrating to the drm ports. 733 73420190131: 735 Iflib is no longer unconditionally compiled into the kernel. Drivers 736 using iflib and statically compiled into the kernel, now require 737 the 'device iflib' config option. For the same drivers loaded as 738 modules on kernels not having 'device iflib', the iflib.ko module 739 is loaded automatically. 740 74120190125: 742 The IEEE80211_AMPDU_AGE and AH_SUPPORT_AR5416 kernel configuration 743 options no longer exist since r343219 and r343427 respectively; 744 nothing uses them, so they should be just removed from custom 745 kernel config files. 746 74720181230: 748 r342635 changes the way efibootmgr(8) works by requiring users to add 749 the -b (bootnum) parameter for commands where the bootnum was previously 750 specified with each option. For example 'efibootmgr -B 0001' is now 751 'efibootmgr -B -b 0001'. 752 75320181220: 754 r342286 modifies the NFSv4 server so that it obeys vfs.nfsd.nfs_privport 755 in the same as it is applied to NFSv2 and 3. This implies that NFSv4 756 servers that have vfs.nfsd.nfs_privport set will only allow mounts 757 from clients using a reserved port. Since both the FreeBSD and Linux 758 NFSv4 clients use reserved ports by default, this should not affect 759 most NFSv4 mounts. 760 76120181219: 762 The XLP config has been removed. We can't support 64-bit atomics in this 763 kernel because it is running in 32-bit mode. XLP users must transition 764 to running a 64-bit kernel (XLP64 or XLPN32). 765 766 The mips GXEMUL support has been removed from FreeBSD. MALTA* + qemu is 767 the preferred emulator today and we don't need two different ones. 768 769 The old sibyte / swarm / Broadcom BCM1250 support has been 770 removed from the mips port. 771 77220181211: 773 Clang, llvm, lld, lldb, compiler-rt and libc++ have been upgraded to 774 7.0.1. Please see the 20141231 entry below for information about 775 prerequisites and upgrading, if you are not already using clang 3.5.0 776 or higher. 777 77820181211: 779 Remove the timed and netdate programs from the base tree. Setting 780 the time with these daemons has been obsolete for over a decade. 781 78220181126: 783 On amd64, arm64 and armv7 (architectures that install LLVM's ld.lld 784 linker as /usr/bin/ld) GNU ld is no longer installed as ld.bfd, as 785 it produces broken binaries when ifuncs are in use. Users needing 786 GNU ld should install the binutils port or package. 787 78820181123: 789 The BSD crtbegin and crtend code has been enabled by default. It has 790 had extensive testing on amd64, arm64, and i386. It can be disabled 791 by building a world with -DWITHOUT_BSD_CRTBEGIN. 792 79320181115: 794 The set of CTM commands (ctm, ctm_smail, ctm_rmail, ctm_dequeue) 795 has been converted to a port (misc/ctm) and will be removed from 796 FreeBSD-13. It is available as a package (ctm) for all supported 797 FreeBSD versions. 798 79920181110: 800 The default newsyslog.conf(5) file has been changed to only include 801 files in /etc/newsyslog.conf.d/ and /usr/local/etc/newsyslog.conf.d/ if 802 the filenames end in '.conf' and do not begin with a '.'. 803 804 You should check the configuration files in these two directories match 805 this naming convention. You can verify which configuration files are 806 being included using the command: 807 $ newsyslog -Nrv 808 80920181015: 810 Ports for the DRM modules have been simplified. Now, amd64 users should 811 just install the drm-kmod port. All others should install 812 drm-legacy-kmod. 813 814 Graphics hardware that's newer than about 2010 usually works with 815 drm-kmod. For hardware older than 2013, however, some users will need 816 to use drm-legacy-kmod if drm-kmod doesn't work for them. Hardware older 817 than 2008 usually only works in drm-legacy-kmod. The graphics team can 818 only commit to hardware made since 2013 due to the complexity of the 819 market and difficulty to test all the older cards effectively. If you 820 have hardware supported by drm-kmod, you are strongly encouraged to use 821 that as you will get better support. 822 823 Other than KPI chasing, drm-legacy-kmod will not be updated. As outlined 824 elsewhere, the drm and drm2 modules will be eliminated from the src base 825 soon (with a limited exception for arm). Please update to the package 826 asap and report any issues to x11@freebsd.org. 827 828 Generally, anybody using the drm*-kmod packages should add 829 WITHOUT_DRM_MODULE=t and WITHOUT_DRM2_MODULE=t to avoid nasty 830 cross-threading surprises, especially with automatic driver 831 loading from X11 startup. These will become the defaults in 13-current 832 shortly. 833 83420181012: 835 The ixlv(4) driver has been renamed to iavf(4). As a consequence, 836 custom kernel and module loading configuration files must be updated 837 accordingly. Moreover, interfaces previous presented as ixlvN to the 838 system are now exposed as iavfN and network configuration files must 839 be adjusted as necessary. 840 84120181009: 842 OpenSSL has been updated to version 1.1.1. This update included 843 additional various API changes throughout the base system. It is 844 important to rebuild third-party software after upgrading. The value 845 of __FreeBSD_version has been bumped accordingly. 846 84720181006: 848 The legacy DRM modules and drivers have now been added to the loader's 849 module blacklist, in favor of loading them with kld_list in rc.conf(5). 850 The module blacklist may be overridden with the loader.conf(5) 851 'module_blacklist' variable, but loading them via rc.conf(5) is strongly 852 encouraged. 853 85420181002: 855 The cam(4) based nda(4) driver will be used over nvd(4) by default on 856 powerpc64. You may set 'options NVME_USE_NVD=1' in your kernel conf or 857 loader tunable 'hw.nvme.use_nvd=1' if you wish to use the existing 858 driver. Make sure to edit /boot/etc/kboot.conf and fstab to use the 859 nda device name. 860 86120180913: 862 Reproducible build mode is now on by default, in preparation for 863 FreeBSD 12.0. This eliminates build metadata such as the user, 864 host, and time from the kernel (and uname), unless the working tree 865 corresponds to a modified checkout from a version control system. 866 The previous behavior can be obtained by setting the /etc/src.conf 867 knob WITHOUT_REPRODUCIBLE_BUILD. 868 86920180826: 870 The Yarrow CSPRNG has been removed from the kernel as it has not been 871 supported by its designers since at least 2003. Fortuna has been the 872 default since FreeBSD-11. 873 87420180822: 875 devctl freeze/thaw have gone into the tree, the rc scripts have been 876 updated to use them and devmatch has been changed. You should update 877 kernel, userland and rc scripts all at the same time. 878 87920180818: 880 The default interpreter has been switched from 4th to Lua. 881 LOADER_DEFAULT_INTERP, documented in build(7), will override the default 882 interpreter. If you have custom FORTH code you will need to set 883 LOADER_DEFAULT_INTERP=4th (valid values are 4th, lua or simp) in 884 src.conf for the build. This will create default hard links between 885 loader and loader_4th instead of loader and loader_lua, the new default. 886 If you are using UEFI it will create the proper hard link to loader.efi. 887 888 bhyve uses userboot.so. It remains 4th-only until some issues are solved 889 regarding coexisting with multiple versions of FreeBSD are resolved. 890 89120180815: 892 ls(1) now respects the COLORTERM environment variable used in other 893 systems and software to indicate that a colored terminal is both 894 supported and desired. If ls(1) is suddenly emitting colors, they may 895 be disabled again by either removing the unwanted COLORTERM from your 896 environment, or using `ls --color=never`. The ls(1) specific CLICOLOR 897 may not be observed in a future release. 898 89920180808: 900 The default pager for most commands has been changed to "less". To 901 restore the old behavior, set PAGER="more" and MANPAGER="more -s" in 902 your environment. 903 90420180731: 905 The jedec_ts(4) driver has been removed. A superset of its functionality 906 is available in the jedec_dimm(4) driver, and the manpage for that 907 driver includes migration instructions. If you have "device jedec_ts" 908 in your kernel configuration file, it must be removed. 909 91020180730: 911 amd64/GENERIC now has EFI runtime services, EFIRT, enabled by default. 912 This should have no effect if the kernel is booted via BIOS/legacy boot. 913 EFIRT may be disabled via a loader tunable, efi.rt.disabled, if a system 914 has a buggy firmware that prevents a successful boot due to use of 915 runtime services. 916 91720180727: 918 Atmel AT91RM9200 and AT91SAM9, Cavium CNS 11xx and XScale 919 support has been removed from the tree. These ports were 920 obsolete and/or known to be broken for many years. 921 92220180723: 923 loader.efi has been augmented to participate more fully in the 924 UEFI boot manager protocol. loader.efi will now look at the 925 BootXXXX environment variable to determine if a specific kernel 926 or root partition was specified. XXXX is derived from BootCurrent. 927 efibootmgr(8) manages these standard UEFI variables. 928 92920180720: 930 zfsloader's functionality has now been folded into loader. 931 zfsloader is no longer necessary once you've updated your 932 boot blocks. For a transition period, we will install a 933 hardlink for zfsloader to loader to allow a smooth transition 934 until the boot blocks can be updated (hard link because old 935 zfs boot blocks don't understand symlinks). 936 93720180719: 938 ARM64 now have efifb support, if you want to have serial console 939 on your arm64 board when an screen is connected and the bootloader 940 setup a frame buffer for us to use, just add : 941 boot_serial=YES 942 boot_multicons=YES 943 in /boot/loader.conf 944 For Raspberry Pi 3 (RPI) users, this is needed even if you don't have 945 an screen connected as the firmware will setup a frame buffer are that 946 u-boot will expose as an EFI frame buffer. 947 94820180719: 949 New uid:gid added, ntpd:ntpd (123:123). Be sure to run mergemaster 950 or take steps to update /etc/passwd before doing installworld on 951 existing systems. Do not skip the "mergemaster -Fp" step before 952 installworld, as described in the update procedures near the bottom 953 of this document. Also, rc.d/ntpd now starts ntpd(8) as user ntpd 954 if the new mac_ntpd(4) policy is available, unless ntpd_flags or 955 the ntp config file contain options that change file/dir locations. 956 When such options (e.g., "statsdir" or "crypto") are used, ntpd can 957 still be run as non-root by setting ntpd_user=ntpd in rc.conf, after 958 taking steps to ensure that all required files/dirs are accessible 959 by the ntpd user. 960 96120180717: 962 Big endian arm support has been removed. 963 96420180711: 965 The static environment setup in kernel configs is no longer mutually 966 exclusive with the loader(8) environment by default. In order to 967 restore the previous default behavior of disabling the loader(8) 968 environment if a static environment is present, you must specify 969 loader_env.disabled=1 in the static environment. 970 97120180705: 972 The ABI of syscalls used by management tools like sockstat and 973 netstat has been broken to allow 32-bit binaries to work on 974 64-bit kernels without modification. These programs will need 975 to match the kernel in order to function. External programs may 976 require minor modifications to accommodate a change of type in 977 structures from pointers to 64-bit virtual addresses. 978 97920180702: 980 On i386 and amd64 atomics are now inlined. Out of tree modules using 981 atomics will need to be rebuilt. 982 98320180701: 984 The '%I' format in the kern.corefile sysctl limits the number of 985 core files that a process can generate to the number stored in the 986 debug.ncores sysctl. The '%I' format is replaced by the single digit 987 index. Previously, if all indexes were taken the kernel would overwrite 988 only a core file with the highest index in a filename. 989 Currently the system will create a new core file if there is a free 990 index or if all slots are taken it will overwrite the oldest one. 991 99220180630: 993 Clang, llvm, lld, lldb, compiler-rt and libc++ have been upgraded to 994 6.0.1. Please see the 20141231 entry below for information about 995 prerequisites and upgrading, if you are not already using clang 3.5.0 996 or higher. 997 99820180628: 999 r335753 introduced a new quoting method. However, etc/devd/devmatch.conf 1000 needed to be changed to work with it. This change was made with r335763 1001 and requires a mergemaster / etcupdate / etc to update the installed 1002 file. 1003 100420180612: 1005 r334930 changed the interface between the NFS modules, so they all 1006 need to be rebuilt. r335018 did a __FreeBSD_version bump for this. 1007 100820180530: 1009 As of r334391 lld is the default amd64 system linker; it is installed 1010 as /usr/bin/ld. Kernel build workarounds (see 20180510 entry) are no 1011 longer necessary. 1012 101320180530: 1014 The kernel / userland interface for devinfo changed, so you'll 1015 need a new kernel and userland as a pair for it to work (rebuilding 1016 lib/libdevinfo is all that's required). devinfo and devmatch will 1017 not work, but everything else will when there's a mismatch. 1018 101920180523: 1020 The on-disk format for hwpmc callchain records has changed to include 1021 threadid corresponding to a given record. This changes the field offsets 1022 and thus requires that libpmcstat be rebuilt before using a kernel 1023 later than r334108. 1024 102520180517: 1026 The vxge(4) driver has been removed. This driver was introduced into 1027 HEAD one week before the Exar left the Ethernet market and is not 1028 known to be used. If you have device vxge in your kernel config file 1029 it must be removed. 1030 103120180510: 1032 The amd64 kernel now requires a ld that supports ifunc to produce a 1033 working kernel, either lld or a newer binutils. lld is built by default 1034 on amd64, and the 'buildkernel' target uses it automatically. However, 1035 it is not the default linker, so building the kernel the traditional 1036 way requires LD=ld.lld on the command line (or LD=/usr/local/bin/ld for 1037 binutils port/package). lld will soon be default, and this requirement 1038 will go away. 1039 1040 NOTE: As of r334391 lld is the default system linker on amd64, and no 1041 workaround is necessary. 1042 104320180508: 1044 The nxge(4) driver has been removed. This driver was for PCI-X 10g 1045 cards made by s2io/Neterion. The company was acquired by Exar and 1046 no longer sells or supports Ethernet products. If you have device 1047 nxge in your kernel config file it must be removed. 1048 104920180504: 1050 The tz database (tzdb) has been updated to 2018e. This version more 1051 correctly models time stamps in time zones with negative DST such as 1052 Europe/Dublin (from 1971 on), Europe/Prague (1946/7), and 1053 Africa/Windhoek (1994/2017). This does not affect the UT offsets, only 1054 time zone abbreviations and the tm_isdst flag. 1055 105620180502: 1057 The ixgb(4) driver has been removed. This driver was for an early and 1058 uncommon legacy PCI 10GbE for a single ASIC, Intel 82597EX. Intel 1059 quickly shifted to the long lived ixgbe family. If you have device 1060 ixgb in your kernel config file it must be removed. 1061 106220180501: 1063 The lmc(4) driver has been removed. This was a WAN interface 1064 card that was already reportedly rare in 2003, and had an ambiguous 1065 license. If you have device lmc in your kernel config file it must 1066 be removed. 1067 106820180413: 1069 Support for Arcnet networks has been removed. If you have device 1070 arcnet or device cm in your kernel config file they must be 1071 removed. 1072 107320180411: 1074 Support for FDDI networks has been removed. If you have device 1075 fddi or device fpa in your kernel config file they must be 1076 removed. 1077 107820180406: 1079 In addition to supporting RFC 3164 formatted messages, the 1080 syslogd(8) service is now capable of parsing RFC 5424 formatted 1081 log messages. The main benefit of using RFC 5424 is that clients 1082 may now send log messages with timestamps containing year numbers, 1083 microseconds and time zone offsets. 1084 1085 Similarly, the syslog(3) C library function has been altered to 1086 send RFC 5424 formatted messages to the local system logging 1087 daemon. On systems using syslogd(8), this change should have no 1088 negative impact, as long as syslogd(8) and the C library are 1089 updated at the same time. On systems using a different system 1090 logging daemon, it may be necessary to make configuration 1091 adjustments, depending on the software used. 1092 1093 When using syslog-ng, add the 'syslog-protocol' flag to local 1094 input sources to enable parsing of RFC 5424 formatted messages: 1095 1096 source src { 1097 unix-dgram("/var/run/log" flags(syslog-protocol)); 1098 } 1099 1100 When using rsyslog, disable the 'SysSock.UseSpecialParser' option 1101 of the 'imuxsock' module to let messages be processed by the 1102 regular RFC 3164/5424 parsing pipeline: 1103 1104 module(load="imuxsock" SysSock.UseSpecialParser="off") 1105 1106 Do note that these changes only affect communication between local 1107 applications and syslogd(8). The format that syslogd(8) uses to 1108 store messages on disk or forward messages to other systems 1109 remains unchanged. syslogd(8) still uses RFC 3164 for these 1110 purposes. Options to customize this behaviour will be added in the 1111 future. Utilities that process log files stored in /var/log are 1112 thus expected to continue to function as before. 1113 1114 __FreeBSD_version has been incremented to 1200061 to denote this 1115 change. 1116 111720180328: 1118 Support for token ring networks has been removed. If you 1119 have "device token" in your kernel config you should remove 1120 it. No device drivers supported token ring. 1121 112220180323: 1123 makefs was modified to be able to tag ISO9660 El Torito boot catalog 1124 entries as EFI instead of overloading the i386 tag as done previously. 1125 The amd64 mkisoimages.sh script used to build amd64 ISO images for 1126 release was updated to use this. This may mean that makefs must be 1127 updated before "make cdrom" can be run in the release directory. This 1128 should be as simple as: 1129 1130 $ cd $SRCDIR/usr.sbin/makefs 1131 $ make depend all install 1132 113320180212: 1134 FreeBSD boot loader enhanced with Lua scripting. It's purely opt-in for 1135 now by building WITH_LOADER_LUA and WITHOUT_FORTH in /etc/src.conf. 1136 Co-existence for the transition period will come shortly. Booting is a 1137 complex environment and test coverage for Lua-enabled loaders has been 1138 thin, so it would be prudent to assume it might not work and make 1139 provisions for backup boot methods. 1140 114120180211: 1142 devmatch functionality has been turned on in devd. It will automatically 1143 load drivers for unattached devices. This may cause unexpected drivers 1144 to be loaded. Please report any problems to current@ and 1145 imp@freebsd.org. 1146 114720180114: 1148 Clang, llvm, lld, lldb, compiler-rt and libc++ have been upgraded to 1149 6.0.0. Please see the 20141231 entry below for information about 1150 prerequisites and upgrading, if you are not already using clang 3.5.0 1151 or higher. 1152 115320180110: 1154 LLVM's lld linker is now used as the FreeBSD/amd64 bootstrap linker. 1155 This means it is used to link the kernel and userland libraries and 1156 executables, but is not yet installed as /usr/bin/ld by default. 1157 1158 To revert to ld.bfd as the bootstrap linker, in /etc/src.conf set 1159 WITHOUT_LLD_BOOTSTRAP=yes 1160 116120180110: 1162 On i386, pmtimer has been removed. Its functionality has been folded 1163 into apm. It was a no-op on ACPI in current for a while now (but was 1164 still needed on i386 in FreeBSD 11 and earlier). Users may need to 1165 remove it from kernel config files. 1166 116720180104: 1168 The use of RSS hash from the network card aka flowid has been 1169 disabled by default for lagg(4) as it's currently incompatible with 1170 the lacp and loadbalance protocols. 1171 1172 This can be re-enabled by setting the following in loader.conf: 1173 net.link.lagg.default_use_flowid="1" 1174 117520180102: 1176 The SW_WATCHDOG option is no longer necessary to enable the 1177 hardclock-based software watchdog if no hardware watchdog is 1178 configured. As before, SW_WATCHDOG will cause the software 1179 watchdog to be enabled even if a hardware watchdog is configured. 1180 118120171215: 1182 r326887 fixes the issue described in the 20171214 UPDATING entry. 1183 r326888 flips the switch back to building GELI support always. 1184 118520171214: 1186 r362593 broke ZFS + GELI support for reasons unknown. However, 1187 it also broke ZFS support generally, so GELI has been turned off 1188 by default as the lesser evil in r326857. If you boot off ZFS and/or 1189 GELI, it might not be a good time to update. 1190 119120171125: 1192 PowerPC users must update loader(8) by rebuilding world before 1193 installing a new kernel, as the protocol connecting them has 1194 changed. Without the update, loader metadata will not be passed 1195 successfully to the kernel and users will have to enter their 1196 root partition at the kernel mountroot prompt to continue booting. 1197 Newer versions of loader can boot old kernels without issue. 1198 119920171110: 1200 The LOADER_FIREWIRE_SUPPORT build variable has been renamed to 1201 WITH/OUT_LOADER_FIREWIRE. LOADER_{NO_,}GELI_SUPPORT has been renamed 1202 to WITH/OUT_LOADER_GELI. 1203 120420171106: 1205 The naive and non-compliant support of posix_fallocate(2) in ZFS 1206 has been removed as of r325320. The system call now returns EINVAL 1207 when used on a ZFS file. Although the new behavior complies with the 1208 standard, some consumers are not prepared to cope with it. 1209 One known victim is lld prior to r325420. 1210 121120171102: 1212 Building in a FreeBSD src checkout will automatically create object 1213 directories now rather than store files in the current directory if 1214 'make obj' was not ran. Calling 'make obj' is no longer necessary. 1215 This feature can be disabled by setting WITHOUT_AUTO_OBJ=yes in 1216 /etc/src-env.conf (not /etc/src.conf), or passing the option in the 1217 environment. 1218 121920171101: 1220 The default MAKEOBJDIR has changed from /usr/obj/<srcdir> for native 1221 builds, and /usr/obj/<arch>/<srcdir> for cross-builds, to a unified 1222 /usr/obj/<srcdir>/<arch>. This behavior can be changed to the old 1223 format by setting WITHOUT_UNIFIED_OBJDIR=yes in /etc/src-env.conf, 1224 the environment, or with -DWITHOUT_UNIFIED_OBJDIR when building. 1225 The UNIFIED_OBJDIR option is a transitional feature that will be 1226 removed for 12.0 release; please migrate to the new format for any 1227 tools by looking up the OBJDIR used by 'make -V .OBJDIR' means rather 1228 than hardcoding paths. 1229 123020171028: 1231 The native-xtools target no longer installs the files by default to the 1232 OBJDIR. Use the native-xtools-install target with a DESTDIR to install 1233 to ${DESTDIR}/${NXTP} where NXTP defaults to /nxb-bin. 1234 123520171021: 1236 As part of the boot loader infrastructure cleanup, LOADER_*_SUPPORT 1237 options are changing from controlling the build if defined / undefined 1238 to controlling the build with explicit 'yes' or 'no' values. They will 1239 shift to WITH/WITHOUT options to match other options in the system. 1240 124120171010: 1242 libstand has turned into a private library for sys/boot use only. 1243 It is no longer supported as a public interface outside of sys/boot. 1244 124520171005: 1246 The arm port has split armv6 into armv6 and armv7. armv7 is now 1247 a valid TARGET_ARCH/MACHINE_ARCH setting. If you have an armv7 system 1248 and are running a kernel from before r324363, you will need to add 1249 MACHINE_ARCH=armv7 to 'make buildworld' to do a native build. 1250 125120171003: 1252 When building multiple kernels using KERNCONF, non-existent KERNCONF 1253 files will produce an error and buildkernel will fail. Previously 1254 missing KERNCONF files silently failed giving no indication as to 1255 why, only to subsequently discover during installkernel that the 1256 desired kernel was never built in the first place. 1257 125820170912: 1259 The default serial number format for CTL LUNs has changed. This will 1260 affect users who use /dev/diskid/* device nodes, or whose FibreChannel 1261 or iSCSI clients care about their LUNs' serial numbers. Users who 1262 require serial number stability should hardcode serial numbers in 1263 /etc/ctl.conf . 1264 126520170912: 1266 For 32-bit arm compiled for hard-float support, soft-floating point 1267 binaries now always get their shared libraries from 1268 LD_SOFT_LIBRARY_PATH (in the past, this was only used if 1269 /usr/libsoft also existed). Only users with a hard-float ld.so, but 1270 soft-float everything else should be affected. 1271 127220170826: 1273 The geli password typed at boot is now hidden. To restore the previous 1274 behavior, see geli(8) for configuration options. 1275 127620170825: 1277 Move PMTUD blackhole counters to TCPSTATS and remove them from bare 1278 sysctl values. Minor nit, but requires a rebuild of both world/kernel 1279 to complete. 1280 128120170814: 1282 "make check" behavior (made in ^/head@r295380) has been changed to 1283 execute from a limited sandbox, as opposed to executing from 1284 ${TESTSDIR}. 1285 1286 Behavioral changes: 1287 - The "beforecheck" and "aftercheck" targets are now specified. 1288 - ${CHECKDIR} (added in commit noted above) has been removed. 1289 - Legacy behavior can be enabled by setting 1290 WITHOUT_MAKE_CHECK_USE_SANDBOX in src.conf(5) or the environment. 1291 1292 If the limited sandbox mode is enabled, "make check" will execute 1293 "make distribution", then install, execute the tests, and clean up the 1294 sandbox if successful. 1295 1296 The "make distribution" and "make install" targets are typically run as 1297 root to set appropriate permissions and ownership at installation time. 1298 The end-user should set "WITH_INSTALL_AS_USER" in src.conf(5) or the 1299 environment if executing "make check" with limited sandbox mode using 1300 an unprivileged user. 1301 130220170808: 1303 Since the switch to GPT disk labels, fsck for UFS/FFS has been 1304 unable to automatically find alternate superblocks. As of r322297, 1305 the information needed to find alternate superblocks has been 1306 moved to the end of the area reserved for the boot block. 1307 Filesystems created with a newfs of this vintage or later 1308 will create the recovery information. If you have a filesystem 1309 created prior to this change and wish to have a recovery block 1310 created for your filesystem, you can do so by running fsck in 1311 foreground mode (i.e., do not use the -p or -y options). As it 1312 starts, fsck will ask ``SAVE DATA TO FIND ALTERNATE SUPERBLOCKS'' 1313 to which you should answer yes. 1314 131520170728: 1316 As of r321665, an NFSv4 server configuration that services 1317 Kerberos mounts or clients that do not support the uid/gid in 1318 owner/owner_group string capability, must explicitly enable 1319 the nfsuserd daemon by adding nfsuserd_enable="YES" to the 1320 machine's /etc/rc.conf file. 1321 132220170722: 1323 Clang, llvm, lldb, compiler-rt and libc++ have been upgraded to 5.0.0. 1324 Please see the 20141231 entry below for information about prerequisites 1325 and upgrading, if you are not already using clang 3.5.0 or higher. 1326 132720170701: 1328 WITHOUT_RCMDS is now the default. Set WITH_RCMDS if you need the 1329 r-commands (rlogin, rsh, etc.) to be built with the base system. 1330 133120170625: 1332 The FreeBSD/powerpc platform now uses a 64-bit type for time_t. This is 1333 a very major ABI incompatible change, so users of FreeBSD/powerpc must 1334 be careful when performing source upgrades. It is best to run 1335 'make installworld' from an alternate root system, either a live 1336 CD/memory stick, or a temporary root partition. Additionally, all ports 1337 must be recompiled. powerpc64 is largely unaffected, except in the case 1338 of 32-bit compatibility. All 32-bit binaries will be affected. 1339 134020170623: 1341 Forward compatibility for the "ino64" project have been committed. This 1342 will allow most new binaries to run on older kernels in a limited 1343 fashion. This prevents many of the common foot-shooting actions in the 1344 upgrade as well as the limited ability to roll back the kernel across 1345 the ino64 upgrade. Complicated use cases may not work properly, though 1346 enough simpler ones work to allow recovery in most situations. 1347 134820170620: 1349 Switch back to the BSDL dtc (Device Tree Compiler). Set WITH_GPL_DTC 1350 if you require the GPL compiler. 1351 135220170618: 1353 The internal ABI used for communication between the NFS kernel modules 1354 was changed by r320085, so __FreeBSD_version was bumped to 1355 ensure all the NFS related modules are updated together. 1356 135720170617: 1358 The ABI of struct event was changed by extending the data 1359 member to 64bit and adding ext fields. For upgrade, same 1360 precautions as for the entry 20170523 "ino64" must be 1361 followed. 1362 136320170531: 1364 The GNU roff toolchain has been removed from base. To render manpages 1365 which are not supported by mandoc(1), man(1) can fallback on GNU roff 1366 from ports (and recommends to install it). 1367 To render roff(7) documents, consider using GNU roff from ports or the 1368 heirloom doctools roff toolchain from ports via pkg install groff or 1369 via pkg install heirloom-doctools. 1370 137120170524: 1372 The ath(4) and ath_hal(4) modules now build piecemeal to allow for 1373 smaller runtime footprint builds. This is useful for embedded systems 1374 which only require one chipset support. 1375 1376 If you load it as a module, make sure this is in /boot/loader.conf: 1377 1378 if_ath_load="YES" 1379 1380 This will load the HAL, all chip/RF backends and if_ath_pci. 1381 If you have if_ath_pci in /boot/loader.conf, ensure it is after 1382 if_ath or it will not load any HAL chipset support. 1383 1384 If you want to selectively load things (eg on cheaper ARM/MIPS 1385 platforms where RAM is at a premium) you should: 1386 1387 * load ath_hal 1388 * load the chip modules in question 1389 * load ath_rate, ath_dfs 1390 * load ath_main 1391 * load if_ath_pci and/or if_ath_ahb depending upon your particular 1392 bus bind type - this is where probe/attach is done. 1393 1394 For further comments/feedback, poke adrian@ . 1395 139620170523: 1397 The "ino64" 64-bit inode project has been committed, which extends 1398 a number of types to 64 bits. Upgrading in place requires care and 1399 adherence to the documented upgrade procedure. 1400 1401 If using a custom kernel configuration ensure that the 1402 COMPAT_FREEBSD11 option is included (as during the upgrade the 1403 system will be running the ino64 kernel with the existing world). 1404 1405 For the safest in-place upgrade begin by removing previous build 1406 artifacts via "rm -rf /usr/obj/*". Then, carefully follow the full 1407 procedure documented below under the heading "To rebuild everything and 1408 install it on the current system." Specifically, a reboot is required 1409 after installing the new kernel before installing world. While an 1410 installworld normally works by accident from multiuser after rebooting 1411 the proper kernel, there are many cases where this will fail across this 1412 upgrade and installworld from single user is required. 1413 141420170424: 1415 The NATM framework including the en(4), fatm(4), hatm(4), and 1416 patm(4) devices has been removed. Consumers should plan a 1417 migration before the end-of-life date for FreeBSD 11. 1418 141920170420: 1420 GNU diff has been replaced by a BSD licensed diff. Some features of GNU 1421 diff has not been implemented, if those are needed a newer version of 1422 GNU diff is available via the diffutils package under the gdiff name. 1423 142420170413: 1425 As of r316810 for ipfilter, keep frags is no longer assumed when 1426 keep state is specified in a rule. r316810 aligns ipfilter with 1427 documentation in man pages separating keep frags from keep state. 1428 This allows keep state to be specified without forcing keep frags 1429 and allows keep frags to be specified independently of keep state. 1430 To maintain previous behaviour, also specify keep frags with 1431 keep state (as documented in ipf.conf.5). 1432 143320170407: 1434 arm64 builds now use the base system LLD 4.0.0 linker by default, 1435 instead of requiring that the aarch64-binutils port or package be 1436 installed. To continue using aarch64-binutils, set 1437 CROSS_BINUTILS_PREFIX=/usr/local/aarch64-freebsd/bin . 1438 143920170405: 1440 The UDP optimization in entry 20160818 that added the sysctl 1441 net.inet.udp.require_l2_bcast has been reverted. L2 broadcast 1442 packets will no longer be treated as L3 broadcast packets. 1443 144420170331: 1445 Binds and sends to the loopback addresses, IPv6 and IPv4, will now 1446 use any explicitly assigned loopback address available in the jail 1447 instead of using the first assigned address of the jail. 1448 144920170329: 1450 The ctl.ko module no longer implements the iSCSI target frontend: 1451 cfiscsi.ko does instead. 1452 1453 If building cfiscsi.ko as a kernel module, the module can be loaded 1454 via one of the following methods: 1455 - `cfiscsi_load="YES"` in loader.conf(5). 1456 - Add `cfiscsi` to `$kld_list` in rc.conf(5). 1457 - ctladm(8)/ctld(8), when compiled with iSCSI support 1458 (`WITH_ISCSI=yes` in src.conf(5)) 1459 1460 Please see cfiscsi(4) for more details. 1461 146220170316: 1463 The mmcsd.ko module now additionally depends on geom_flashmap.ko. 1464 Also, mmc.ko and mmcsd.ko need to be a matching pair built from the 1465 same source (previously, the dependency of mmcsd.ko on mmc.ko was 1466 missing, but mmcsd.ko now will refuse to load if it is incompatible 1467 with mmc.ko). 1468 146920170315: 1470 The syntax of ipfw(8) named states was changed to avoid ambiguity. 1471 If you have used named states in the firewall rules, you need to modify 1472 them after installworld and before rebooting. Now named states must 1473 be prefixed with colon. 1474 147520170311: 1476 The old drm (sys/dev/drm/) drivers for i915 and radeon have been 1477 removed as the userland we provide cannot use them. The KMS version 1478 (sys/dev/drm2) supports the same hardware. 1479 148020170302: 1481 Clang, llvm, lldb, compiler-rt and libc++ have been upgraded to 4.0.0. 1482 Please see the 20141231 entry below for information about prerequisites 1483 and upgrading, if you are not already using clang 3.5.0 or higher. 1484 148520170221: 1486 The code that provides support for ZFS .zfs/ directory functionality 1487 has been reimplemented. It's not possible now to create a snapshot 1488 by mkdir under .zfs/snapshot/. That should be the only user visible 1489 change. 1490 149120170216: 1492 EISA bus support has been removed. The WITH_EISA option is no longer 1493 valid. 1494 149520170215: 1496 MCA bus support has been removed. 1497 149820170127: 1499 The WITH_LLD_AS_LD / WITHOUT_LLD_AS_LD build knobs have been renamed 1500 WITH_LLD_IS_LD / WITHOUT_LLD_IS_LD, for consistency with CLANG_IS_CC. 1501 150220170112: 1503 The EM_MULTIQUEUE kernel configuration option is deprecated now that 1504 the em(4) driver conforms to iflib specifications. 1505 150620170109: 1507 The igb(4), em(4) and lem(4) ethernet drivers are now implemented via 1508 IFLIB. If you have a custom kernel configuration that excludes em(4) 1509 but you use igb(4), you need to re-add em(4) to your custom 1510 configuration. 1511 151220161217: 1513 Clang, llvm, lldb, compiler-rt and libc++ have been upgraded to 3.9.1. 1514 Please see the 20141231 entry below for information about prerequisites 1515 and upgrading, if you are not already using clang 3.5.0 or higher. 1516 151720161124: 1518 Clang, llvm, lldb, compiler-rt and libc++ have been upgraded to 3.9.0. 1519 Please see the 20141231 entry below for information about prerequisites 1520 and upgrading, if you are not already using clang 3.5.0 or higher. 1521 152220161119: 1523 The layout of the pmap structure has changed for powerpc to put the pmap 1524 statistics at the front for all CPU variations. libkvm(3) and all tools 1525 that link against it need to be recompiled. 1526 152720161030: 1528 isl(4) and cyapa(4) drivers now require a new driver, 1529 chromebook_platform(4), to work properly on Chromebook-class hardware. 1530 On other types of hardware the drivers may need to be configured using 1531 device hints. Please see the corresponding manual pages for details. 1532 153320161017: 1534 The urtwn(4) driver was merged into rtwn(4) and now consists of 1535 rtwn(4) main module + rtwn_usb(4) and rtwn_pci(4) bus-specific 1536 parts. 1537 Also, firmware for RTL8188CE was renamed due to possible name 1538 conflict (rtwnrtl8192cU(B) -> rtwnrtl8192cE(B)) 1539 154020161015: 1541 GNU rcs has been removed from base. It is available as packages: 1542 - rcs: Latest GPLv3 GNU rcs version. 1543 - rcs57: Copy of the latest version of GNU rcs (GPLv2) before it was 1544 removed from base. 1545 154620161008: 1547 Use of the cc_cdg, cc_chd, cc_hd, or cc_vegas congestion control 1548 modules now requires that the kernel configuration contain the 1549 TCP_HHOOK option. (This option is included in the GENERIC kernel.) 1550 155120161003: 1552 The WITHOUT_ELFCOPY_AS_OBJCOPY src.conf(5) knob has been retired. 1553 ELF Tool Chain's elfcopy is always installed as /usr/bin/objcopy. 1554 155520160924: 1556 Relocatable object files with the extension of .So have been renamed 1557 to use an extension of .pico instead. The purpose of this change is 1558 to avoid a name clash with shared libraries on case-insensitive file 1559 systems. On those file systems, foo.So is the same file as foo.so. 1560 156120160918: 1562 GNU rcs has been turned off by default. It can (temporarily) be built 1563 again by adding WITH_RCS knob in src.conf. 1564 Otherwise, GNU rcs is available from packages: 1565 - rcs: Latest GPLv3 GNU rcs version. 1566 - rcs57: Copy of the latest version of GNU rcs (GPLv2) from base. 1567 156820160918: 1569 The backup_uses_rcs functionality has been removed from rc.subr. 1570 157120160908: 1572 The queue(3) debugging macro, QUEUE_MACRO_DEBUG, has been split into 1573 two separate components, QUEUE_MACRO_DEBUG_TRACE and 1574 QUEUE_MACRO_DEBUG_TRASH. Define both for the original 1575 QUEUE_MACRO_DEBUG behavior. 1576 157720160824: 1578 r304787 changed some ioctl interfaces between the iSCSI userspace 1579 programs and the kernel. ctladm, ctld, iscsictl, and iscsid must be 1580 rebuilt to work with new kernels. __FreeBSD_version has been bumped 1581 to 1200005. 1582 158320160818: 1584 The UDP receive code has been updated to only treat incoming UDP 1585 packets that were addressed to an L2 broadcast address as L3 1586 broadcast packets. It is not expected that this will affect any 1587 standards-conforming UDP application. The new behaviour can be 1588 disabled by setting the sysctl net.inet.udp.require_l2_bcast to 1589 0. 1590 159120160818: 1592 Remove the openbsd_poll system call. 1593 __FreeBSD_version has been bumped because of this. 1594 159520160708: 1596 The stable/11 branch has been created from head@r302406. 1597 159820160622: 1599 The libc stub for the pipe(2) system call has been replaced with 1600 a wrapper that calls the pipe2(2) system call and the pipe(2) 1601 system call is now only implemented by the kernels that include 1602 "options COMPAT_FREEBSD10" in their config file (this is the 1603 default). Users should ensure that this option is enabled in 1604 their kernel or upgrade userspace to r302092 before upgrading their 1605 kernel. 1606 160720160527: 1608 CAM now strips the leading spaces from each SCSI disk's serial number. 1609 This will affect users who create UFS filesystems on SCSI disks using 1610 those disk's diskid device nodes. For example, if /etc/fstab 1611 previously contained a line like 1612 "/dev/diskid/DISK-%20%20%20%20%20%20%20ABCDEFG0123456", you should 1613 change it to "/dev/diskid/DISK-ABCDEFG0123456". Users of geom 1614 transforms like gmirror may also be affected. ZFS users should 1615 generally be fine. 1616 161720160523: 1618 The bitstring(3) API has been updated with new functionality and 1619 improved performance. But it is binary-incompatible with the old API. 1620 Objects built with the new headers may not be linked against objects 1621 built with the old headers. 1622 162320160520: 1624 The brk and sbrk functions have been removed from libc on arm64. 1625 Binutils from ports has been updated to not link to these 1626 functions and should be updated to the latest version before 1627 installing a new libc. 1628 162920160517: 1630 The armv6 port now defaults to hard float ABI. Limited support 1631 for running both hardfloat and soft float on the same system 1632 is available using the libraries installed with -DWITH_LIBSOFT. 1633 This has only been tested as an upgrade path for installworld 1634 and packages may fail or need manual intervention to run. New 1635 packages will be needed. 1636 1637 To update an existing self-hosted armv6hf system, you must add 1638 TARGET_ARCH=armv6 on the make command line for both the build 1639 and the install steps. 1640 164120160510: 1642 Kernel modules compiled outside of a kernel build now default to 1643 installing to /boot/modules instead of /boot/kernel. Many kernel 1644 modules built this way (such as those in ports) already overrode 1645 KMODDIR explicitly to install into /boot/modules. However, 1646 manually building and installing a module from /sys/modules will 1647 now install to /boot/modules instead of /boot/kernel. 1648 164920160414: 1650 The CAM I/O scheduler has been committed to the kernel. There should be 1651 no user visible impact. This does enable NCQ Trim on ada SSDs. While the 1652 list of known rogues that claim support for this but actually corrupt 1653 data is believed to be complete, be on the lookout for data 1654 corruption. The known rogue list is believed to be complete: 1655 1656 o Crucial MX100, M550 drives with MU01 firmware. 1657 o Micron M510 and M550 drives with MU01 firmware. 1658 o Micron M500 prior to MU07 firmware 1659 o Samsung 830, 840, and 850 all firmwares 1660 o FCCT M500 all firmwares 1661 1662 Crucial has firmware http://www.crucial.com/usa/en/support-ssd-firmware 1663 with working NCQ TRIM. For Micron branded drives, see your sales rep for 1664 updated firmware. Black listed drives will work correctly because these 1665 drives work correctly so long as no NCQ TRIMs are sent to them. Given 1666 this list is the same as found in Linux, it's believed there are no 1667 other rogues in the market place. All other models from the above 1668 vendors work. 1669 1670 To be safe, if you are at all concerned, you can quirk each of your 1671 drives to prevent NCQ from being sent by setting: 1672 kern.cam.ada.X.quirks="0x2" 1673 in loader.conf. If the drive requires the 4k sector quirk, set the 1674 quirks entry to 0x3. 1675 167620160330: 1677 The FAST_DEPEND build option has been removed and its functionality is 1678 now the one true way. The old mkdep(1) style of 'make depend' has 1679 been removed. See 20160311 for further details. 1680 168120160317: 1682 Resource range types have grown from unsigned long to uintmax_t. All 1683 drivers, and anything using libdevinfo, need to be recompiled. 1684 168520160311: 1686 WITH_FAST_DEPEND is now enabled by default for in-tree and out-of-tree 1687 builds. It no longer runs mkdep(1) during 'make depend', and the 1688 'make depend' stage can safely be skipped now as it is auto ran 1689 when building 'make all' and will generate all SRCS and DPSRCS before 1690 building anything else. Dependencies are gathered at compile time with 1691 -MF flags kept in separate .depend files per object file. Users should 1692 run 'make cleandepend' once if using -DNO_CLEAN to clean out older 1693 stale .depend files. 1694 169520160306: 1696 On amd64, clang 3.8.0 can now insert sections of type AMD64_UNWIND into 1697 kernel modules. Therefore, if you load any kernel modules at boot time, 1698 please install the boot loaders after you install the kernel, but before 1699 rebooting, e.g.: 1700 1701 make buildworld 1702 make buildkernel KERNCONF=YOUR_KERNEL_HERE 1703 make installkernel KERNCONF=YOUR_KERNEL_HERE 1704 make -C sys/boot install 1705 <reboot in single user> 1706 1707 Then follow the usual steps, described in the General Notes section, 1708 below. 1709 171020160305: 1711 Clang, llvm, lldb and compiler-rt have been upgraded to 3.8.0. Please 1712 see the 20141231 entry below for information about prerequisites and 1713 upgrading, if you are not already using clang 3.5.0 or higher. 1714 171520160301: 1716 The AIO subsystem is now a standard part of the kernel. The 1717 VFS_AIO kernel option and aio.ko kernel module have been removed. 1718 Due to stability concerns, asynchronous I/O requests are only 1719 permitted on sockets and raw disks by default. To enable 1720 asynchronous I/O requests on all file types, set the 1721 vfs.aio.enable_unsafe sysctl to a non-zero value. 1722 172320160226: 1724 The ELF object manipulation tool objcopy is now provided by the 1725 ELF Tool Chain project rather than by GNU binutils. It should be a 1726 drop-in replacement, with the addition of arm64 support. The 1727 (temporary) src.conf knob WITHOUT_ELFCOPY_AS_OBJCOPY knob may be set 1728 to obtain the GNU version if necessary. 1729 173020160129: 1731 Building ZFS pools on top of zvols is prohibited by default. That 1732 feature has never worked safely; it's always been prone to deadlocks. 1733 Using a zvol as the backing store for a VM guest's virtual disk will 1734 still work, even if the guest is using ZFS. Legacy behavior can be 1735 restored by setting vfs.zfs.vol.recursive=1. 1736 173720160119: 1738 The NONE and HPN patches has been removed from OpenSSH. They are 1739 still available in the security/openssh-portable port. 1740 174120160113: 1742 With the addition of ypldap(8), a new _ypldap user is now required 1743 during installworld. "mergemaster -p" can be used to add the user 1744 prior to installworld, as documented in the handbook. 1745 174620151216: 1747 The tftp loader (pxeboot) now uses the option root-path directive. As a 1748 consequence it no longer looks for a pxeboot.4th file on the tftp 1749 server. Instead it uses the regular /boot infrastructure as with the 1750 other loaders. 1751 175220151211: 1753 The code to start recording plug and play data into the modules has 1754 been committed. While the old tools will properly build a new kernel, 1755 a number of warnings about "unknown metadata record 4" will be produced 1756 for an older kldxref. To avoid such warnings, make sure to rebuild 1757 the kernel toolchain (or world). Make sure that you have r292078 or 1758 later when trying to build 292077 or later before rebuilding. 1759 176020151207: 1761 Debug data files are now built by default with 'make buildworld' and 1762 installed with 'make installworld'. This facilitates debugging but 1763 requires more disk space both during the build and for the installed 1764 world. Debug files may be disabled by setting WITHOUT_DEBUG_FILES=yes 1765 in src.conf(5). 1766 176720151130: 1768 r291527 changed the internal interface between the nfsd.ko and 1769 nfscommon.ko modules. As such, they must both be upgraded to-gether. 1770 __FreeBSD_version has been bumped because of this. 1771 177220151108: 1773 Add support for unicode collation strings leads to a change of 1774 order of files listed by ls(1) for example. To get back to the old 1775 behaviour, set LC_COLLATE environment variable to "C". 1776 1777 Databases administrators will need to reindex their databases given 1778 collation results will be different. 1779 1780 Due to a bug in install(1) it is recommended to remove the ancient 1781 locales before running make installworld. 1782 1783 rm -rf /usr/share/locale/* 1784 178520151030: 1786 The OpenSSL has been upgraded to 1.0.2d. Any binaries requiring 1787 libcrypto.so.7 or libssl.so.7 must be recompiled. 1788 178920151020: 1790 Qlogic 24xx/25xx firmware images were updated from 5.5.0 to 7.3.0. 1791 Kernel modules isp_2400_multi and isp_2500_multi were removed and 1792 should be replaced with isp_2400 and isp_2500 modules respectively. 1793 179420151017: 1795 The build previously allowed using 'make -n' to not recurse into 1796 sub-directories while showing what commands would be executed, and 1797 'make -n -n' to recursively show commands. Now 'make -n' will recurse 1798 and 'make -N' will not. 1799 180020151012: 1801 If you specify SENDMAIL_MC or SENDMAIL_CF in make.conf, mergemaster 1802 and etcupdate will now use this file. A custom sendmail.cf is now 1803 updated via this mechanism rather than via installworld. If you had 1804 excluded sendmail.cf in mergemaster.rc or etcupdate.conf, you may 1805 want to remove the exclusion or change it to "always install". 1806 /etc/mail/sendmail.cf is now managed the same way regardless of 1807 whether SENDMAIL_MC/SENDMAIL_CF is used. If you are not using 1808 SENDMAIL_MC/SENDMAIL_CF there should be no change in behavior. 1809 181020151011: 1811 Compatibility shims for legacy ATA device names have been removed. 1812 It includes ATA_STATIC_ID kernel option, kern.cam.ada.legacy_aliases 1813 and kern.geom.raid.legacy_aliases loader tunables, kern.devalias.* 1814 environment variables, /dev/ad* and /dev/ar* symbolic links. 1815 181620151006: 1817 Clang, llvm, lldb, compiler-rt and libc++ have been upgraded to 3.7.0. 1818 Please see the 20141231 entry below for information about prerequisites 1819 and upgrading, if you are not already using clang 3.5.0 or higher. 1820 182120150924: 1822 Kernel debug files have been moved to /usr/lib/debug/boot/kernel/, 1823 and renamed from .symbols to .debug. This reduces the size requirements 1824 on the boot partition or file system and provides consistency with 1825 userland debug files. 1826 1827 When using the supported kernel installation method the 1828 /usr/lib/debug/boot/kernel directory will be renamed (to kernel.old) 1829 as is done with /boot/kernel. 1830 1831 Developers wishing to maintain the historical behavior of installing 1832 debug files in /boot/kernel/ can set KERN_DEBUGDIR="" in src.conf(5). 1833 183420150827: 1835 The wireless drivers had undergone changes that remove the 'parent 1836 interface' from the ifconfig -l output. The rc.d network scripts 1837 used to check presence of a parent interface in the list, so old 1838 scripts would fail to start wireless networking. Thus, etcupdate(3) 1839 or mergemaster(8) run is required after kernel update, to update your 1840 rc.d scripts in /etc. 1841 184220150827: 1843 pf no longer supports 'scrub fragment crop' or 'scrub fragment drop-ovl' 1844 These configurations are now automatically interpreted as 1845 'scrub fragment reassemble'. 1846 184720150817: 1848 Kernel-loadable modules for the random(4) device are back. To use 1849 them, the kernel must have 1850 1851 device random 1852 options RANDOM_LOADABLE 1853 1854 kldload(8) can then be used to load random_fortuna.ko 1855 or random_yarrow.ko. Please note that due to the indirect 1856 function calls that the loadable modules need to provide, 1857 the build-in variants will be slightly more efficient. 1858 1859 The random(4) kernel option RANDOM_DUMMY has been retired due to 1860 unpopularity. It was not all that useful anyway. 1861 186220150813: 1863 The WITHOUT_ELFTOOLCHAIN_TOOLS src.conf(5) knob has been retired. 1864 Control over building the ELF Tool Chain tools is now provided by 1865 the WITHOUT_TOOLCHAIN knob. 1866 186720150810: 1868 The polarity of Pulse Per Second (PPS) capture events with the 1869 uart(4) driver has been corrected. Prior to this change the PPS 1870 "assert" event corresponded to the trailing edge of a positive PPS 1871 pulse and the "clear" event was the leading edge of the next pulse. 1872 1873 As the width of a PPS pulse in a typical GPS receiver is on the 1874 order of 1 millisecond, most users will not notice any significant 1875 difference with this change. 1876 1877 Anyone who has compensated for the historical polarity reversal by 1878 configuring a negative offset equal to the pulse width will need to 1879 remove that workaround. 1880 188120150809: 1882 The default group assigned to /dev/dri entries has been changed 1883 from 'wheel' to 'video' with the id of '44'. If you want to have 1884 access to the dri devices please add yourself to the video group 1885 with: 1886 1887 # pw groupmod video -m $USER 1888 188920150806: 1890 The menu.rc and loader.rc files will now be replaced during 1891 upgrades. Please migrate local changes to menu.rc.local and 1892 loader.rc.local instead. 1893 189420150805: 1895 GNU Binutils versions of addr2line, c++filt, nm, readelf, size, 1896 strings and strip have been removed. The src.conf(5) knob 1897 WITHOUT_ELFTOOLCHAIN_TOOLS no longer provides the binutils tools. 1898 189920150728: 1900 As ZFS requires more kernel stack pages than is the default on some 1901 architectures e.g. i386, it now warns if KSTACK_PAGES is less than 1902 ZFS_MIN_KSTACK_PAGES (which is 4 at the time of writing). 1903 1904 Please consider using 'options KSTACK_PAGES=X' where X is greater 1905 than or equal to ZFS_MIN_KSTACK_PAGES i.e. 4 in such configurations. 1906 190720150706: 1908 sendmail has been updated to 8.15.2. Starting with FreeBSD 11.0 1909 and sendmail 8.15, sendmail uses uncompressed IPv6 addresses by 1910 default, i.e., they will not contain "::". For example, instead 1911 of ::1, it will be 0:0:0:0:0:0:0:1. This permits a zero subnet 1912 to have a more specific match, such as different map entries for 1913 IPv6:0:0 vs IPv6:0. This change requires that configuration 1914 data (including maps, files, classes, custom ruleset, etc.) must 1915 use the same format, so make certain such configuration data is 1916 upgrading. As a very simple check search for patterns like 1917 'IPv6:[0-9a-fA-F:]*::' and 'IPv6::'. To return to the old 1918 behavior, set the m4 option confUSE_COMPRESSED_IPV6_ADDRESSES or 1919 the cf option UseCompressedIPv6Addresses. 1920 192120150630: 1922 The default kernel entropy-processing algorithm is now 1923 Fortuna, replacing Yarrow. 1924 1925 Assuming you have 'device random' in your kernel config 1926 file, the configurations allow a kernel option to override 1927 this default. You may choose *ONE* of: 1928 1929 options RANDOM_YARROW # Legacy /dev/random algorithm. 1930 options RANDOM_DUMMY # Blocking-only driver. 1931 1932 If you have neither, you get Fortuna. For most people, 1933 read no further, Fortuna will give a /dev/random that works 1934 like it always used to, and the difference will be irrelevant. 1935 1936 If you remove 'device random', you get *NO* kernel-processed 1937 entropy at all. This may be acceptable to folks building 1938 embedded systems, but has complications. Carry on reading, 1939 and it is assumed you know what you need. 1940 1941 *PLEASE* read random(4) and random(9) if you are in the 1942 habit of tweaking kernel configs, and/or if you are a member 1943 of the embedded community, wanting specific and not-usual 1944 behaviour from your security subsystems. 1945 1946 NOTE!! If you use RANDOM_DUMMY and/or have no 'device 1947 random', you will NOT have a functioning /dev/random, and 1948 many cryptographic features will not work, including SSH. 1949 You may also find strange behaviour from the random(3) set 1950 of library functions, in particular sranddev(3), srandomdev(3) 1951 and arc4random(3). The reason for this is that the KERN_ARND 1952 sysctl only returns entropy if it thinks it has some to 1953 share, and with RANDOM_DUMMY or no 'device random' this 1954 will never happen. 1955 195620150623: 1957 An additional fix for the issue described in the 20150614 sendmail 1958 entry below has been committed in revision 284717. 1959 196020150616: 1961 FreeBSD's old make (fmake) has been removed from the system. It is 1962 available as the devel/fmake port or via pkg install fmake. 1963 196420150615: 1965 The fix for the issue described in the 20150614 sendmail entry 1966 below has been committed in revision 284436. The work 1967 around described in that entry is no longer needed unless the 1968 default setting is overridden by a confDH_PARAMETERS configuration 1969 setting of '5' or pointing to a 512 bit DH parameter file. 1970 197120150614: 1972 ALLOW_DEPRECATED_ATF_TOOLS/ATFFILE support has been removed from 1973 atf.test.mk (included from bsd.test.mk). Please upgrade devel/atf 1974 and devel/kyua to version 0.20+ and adjust any calling code to work 1975 with Kyuafile and kyua. 1976 197720150614: 1978 The import of openssl to address the FreeBSD-SA-15:10.openssl 1979 security advisory includes a change which rejects handshakes 1980 with DH parameters below 768 bits. sendmail releases prior 1981 to 8.15.2 (not yet released), defaulted to a 512 bit 1982 DH parameter setting for client connections. To work around 1983 this interoperability, sendmail can be configured to use a 1984 2048 bit DH parameter by: 1985 1986 1. Edit /etc/mail/`hostname`.mc 1987 2. If a setting for confDH_PARAMETERS does not exist or 1988 exists and is set to a string beginning with '5', 1989 replace it with '2'. 1990 3. If a setting for confDH_PARAMETERS exists and is set to 1991 a file path, create a new file with: 1992 openssl dhparam -out /path/to/file 2048 1993 4. Rebuild the .cf file: 1994 cd /etc/mail/; make; make install 1995 5. Restart sendmail: 1996 cd /etc/mail/; make restart 1997 1998 A sendmail patch is coming, at which time this file will be 1999 updated. 2000 200120150604: 2002 Generation of legacy formatted entries have been disabled by default 2003 in pwd_mkdb(8), as all base system consumers of the legacy formatted 2004 entries were converted to use the new format by default when the new, 2005 machine independent format have been added and supported since FreeBSD 2006 5.x. 2007 2008 Please see the pwd_mkdb(8) manual page for further details. 2009 201020150525: 2011 Clang and llvm have been upgraded to 3.6.1 release. Please see the 2012 20141231 entry below for information about prerequisites and upgrading, 2013 if you are not already using 3.5.0 or higher. 2014 201520150521: 2016 TI platform code switched to using vendor DTS files and this update 2017 may break existing systems running on Beaglebone, Beaglebone Black, 2018 and Pandaboard: 2019 2020 - dtb files should be regenerated/reinstalled. Filenames are the 2021 same but content is different now 2022 - GPIO addressing was changed, now each GPIO bank (32 pins per bank) 2023 has its own /dev/gpiocX device, e.g. pin 121 on /dev/gpioc0 in old 2024 addressing scheme is now pin 25 on /dev/gpioc3. 2025 - Pandaboard: /etc/ttys should be updated, serial console device is 2026 now /dev/ttyu2, not /dev/ttyu0 2027 202820150501: 2029 soelim(1) from gnu/usr.bin/groff has been replaced by usr.bin/soelim. 2030 If you need the GNU extension from groff soelim(1), install groff 2031 from package: pkg install groff, or via ports: textproc/groff. 2032 203320150423: 2034 chmod, chflags, chown and chgrp now affect symlinks in -R mode as 2035 defined in symlink(7); previously symlinks were silently ignored. 2036 203720150415: 2038 The const qualifier has been removed from iconv(3) to comply with 2039 POSIX. The ports tree is aware of this from r384038 onwards. 2040 204120150416: 2042 Libraries specified by LIBADD in Makefiles must have a corresponding 2043 DPADD_<lib> variable to ensure correct dependencies. This is now 2044 enforced in src.libnames.mk. 2045 204620150324: 2047 From legacy ata(4) driver was removed support for SATA controllers 2048 supported by more functional drivers ahci(4), siis(4) and mvs(4). 2049 Kernel modules ataahci and ataadaptec were removed completely, 2050 replaced by ahci and mvs modules respectively. 2051 205220150315: 2053 Clang, llvm and lldb have been upgraded to 3.6.0 release. Please see 2054 the 20141231 entry below for information about prerequisites and 2055 upgrading, if you are not already using 3.5.0 or higher. 2056 205720150307: 2058 The 32-bit PowerPC kernel has been changed to a position-independent 2059 executable. This can only be booted with a version of loader(8) 2060 newer than January 31, 2015, so make sure to update both world and 2061 kernel before rebooting. 2062 206320150217: 2064 If you are running a -CURRENT kernel since r273872 (Oct 30th, 2014), 2065 but before r278950, the RNG was not seeded properly. Immediately 2066 upgrade the kernel to r278950 or later and regenerate any keys (e.g. 2067 ssh keys or openssl keys) that were generated w/ a kernel from that 2068 range. This does not affect programs that directly used /dev/random 2069 or /dev/urandom. All userland uses of arc4random(3) are affected. 2070 207120150210: 2072 The autofs(4) ABI was changed in order to restore binary compatibility 2073 with 10.1-RELEASE. The automountd(8) daemon needs to be rebuilt to work 2074 with the new kernel. 2075 207620150131: 2077 The powerpc64 kernel has been changed to a position-independent 2078 executable. This can only be booted with a new version of loader(8), 2079 so make sure to update both world and kernel before rebooting. 2080 208120150118: 2082 Clang and llvm have been upgraded to 3.5.1 release. This is a bugfix 2083 only release, no new features have been added. Please see the 20141231 2084 entry below for information about prerequisites and upgrading, if you 2085 are not already using 3.5.0. 2086 208720150107: 2088 ELF tools addr2line, elfcopy (strip), nm, size, and strings are now 2089 taken from the ELF Tool Chain project rather than GNU binutils. They 2090 should be drop-in replacements, with the addition of arm64 support. 2091 The WITHOUT_ELFTOOLCHAIN_TOOLS= knob may be used to obtain the 2092 binutils tools, if necessary. See 20150805 for updated information. 2093 209420150105: 2095 The default Unbound configuration now enables remote control 2096 using a local socket. Users who have already enabled the 2097 local_unbound service should regenerate their configuration 2098 by running "service local_unbound setup" as root. 2099 210020150102: 2101 The GNU texinfo and GNU info pages have been removed. 2102 To be able to view GNU info pages please install texinfo from ports. 2103 210420141231: 2105 Clang, llvm and lldb have been upgraded to 3.5.0 release. 2106 2107 As of this release, a prerequisite for building clang, llvm and lldb is 2108 a C++11 capable compiler and C++11 standard library. This means that to 2109 be able to successfully build the cross-tools stage of buildworld, with 2110 clang as the bootstrap compiler, your system compiler or cross compiler 2111 should either be clang 3.3 or later, or gcc 4.8 or later, and your 2112 system C++ library should be libc++, or libdstdc++ from gcc 4.8 or 2113 later. 2114 2115 On any standard FreeBSD 10.x or 11.x installation, where clang and 2116 libc++ are on by default (that is, on x86 or arm), this should work out 2117 of the box. 2118 2119 On 9.x installations where clang is enabled by default, e.g. on x86 and 2120 powerpc, libc++ will not be enabled by default, so libc++ should be 2121 built (with clang) and installed first. If both clang and libc++ are 2122 missing, build clang first, then use it to build libc++. 2123 2124 On 8.x and earlier installations, upgrade to 9.x first, and then follow 2125 the instructions for 9.x above. 2126 2127 Sparc64 and mips users are unaffected, as they still use gcc 4.2.1 by 2128 default, and do not build clang. 2129 2130 Many embedded systems are resource constrained, and will not be able to 2131 build clang in a reasonable time, or in some cases at all. In those 2132 cases, cross building bootable systems on amd64 is a workaround. 2133 2134 This new version of clang introduces a number of new warnings, of which 2135 the following are most likely to appear: 2136 2137 -Wabsolute-value 2138 2139 This warns in two cases, for both C and C++: 2140 * When the code is trying to take the absolute value of an unsigned 2141 quantity, which is effectively a no-op, and almost never what was 2142 intended. The code should be fixed, if at all possible. If you are 2143 sure that the unsigned quantity can be safely cast to signed, without 2144 loss of information or undefined behavior, you can add an explicit 2145 cast, or disable the warning. 2146 2147 * When the code is trying to take an absolute value, but the called 2148 abs() variant is for the wrong type, which can lead to truncation. 2149 If you want to disable the warning instead of fixing the code, please 2150 make sure that truncation will not occur, or it might lead to unwanted 2151 side-effects. 2152 2153 -Wtautological-undefined-compare and 2154 -Wundefined-bool-conversion 2155 2156 These warn when C++ code is trying to compare 'this' against NULL, while 2157 'this' should never be NULL in well-defined C++ code. However, there is 2158 some legacy (pre C++11) code out there, which actively abuses this 2159 feature, which was less strictly defined in previous C++ versions. 2160 2161 Squid and openjdk do this, for example. The warning can be turned off 2162 for C++98 and earlier, but compiling the code in C++11 mode might result 2163 in unexpected behavior; for example, the parts of the program that are 2164 unreachable could be optimized away. 2165 216620141222: 2167 The old NFS client and server (kernel options NFSCLIENT, NFSSERVER) 2168 kernel sources have been removed. The .h files remain, since some 2169 utilities include them. This will need to be fixed later. 2170 If "mount -t oldnfs ..." is attempted, it will fail. 2171 If the "-o" option on mountd(8), nfsd(8) or nfsstat(1) is used, 2172 the utilities will report errors. 2173 217420141121: 2175 The handling of LOCAL_LIB_DIRS has been altered to skip addition of 2176 directories to top level SUBDIR variable when their parent 2177 directory is included in LOCAL_DIRS. Users with build systems with 2178 such hierarchies and without SUBDIR entries in the parent 2179 directory Makefiles should add them or add the directories to 2180 LOCAL_DIRS. 2181 218220141109: 2183 faith(4) and faithd(8) have been removed from the base system. Faith 2184 has been obsolete for a very long time. 2185 218620141104: 2187 vt(4), the new console driver, is enabled by default. It brings 2188 support for Unicode and double-width characters, as well as 2189 support for UEFI and integration with the KMS kernel video 2190 drivers. 2191 2192 You may need to update your console settings in /etc/rc.conf, 2193 most probably the keymap. During boot, /etc/rc.d/syscons will 2194 indicate what you need to do. 2195 2196 vt(4) still has issues and lacks some features compared to 2197 syscons(4). See the wiki for up-to-date information: 2198 https://wiki.freebsd.org/Newcons 2199 2200 If you want to keep using syscons(4), you can do so by adding 2201 the following line to /boot/loader.conf: 2202 kern.vty=sc 2203 220420141102: 2205 pjdfstest has been integrated into kyua as an opt-in test suite. 2206 Please see share/doc/pjdfstest/README for more details on how to 2207 execute it. 2208 220920141009: 2210 gperf has been removed from the base system for architectures 2211 that use clang. Ports that require gperf will obtain it from the 2212 devel/gperf port. 2213 221420140923: 2215 pjdfstest has been moved from tools/regression/pjdfstest to 2216 contrib/pjdfstest . 2217 221820140922: 2219 At svn r271982, The default linux compat kernel ABI has been adjusted 2220 to 2.6.18 in support of the linux-c6 compat ports infrastructure 2221 update. If you wish to continue using the linux-f10 compat ports, 2222 add compat.linux.osrelease=2.6.16 to your local sysctl.conf. Users are 2223 encouraged to update their linux-compat packages to linux-c6 during 2224 their next update cycle. 2225 222620140729: 2227 The ofwfb driver, used to provide a graphics console on PowerPC when 2228 using vt(4), no longer allows mmap() of all physical memory. This 2229 will prevent Xorg on PowerPC with some ATI graphics cards from 2230 initializing properly unless x11-servers/xorg-server is updated to 2231 1.12.4_8 or newer. 2232 223320140723: 2234 The xdev targets have been converted to using TARGET and 2235 TARGET_ARCH instead of XDEV and XDEV_ARCH. 2236 223720140719: 2238 The default unbound configuration has been modified to address 2239 issues with reverse lookups on networks that use private 2240 address ranges. If you use the local_unbound service, run 2241 "service local_unbound setup" as root to regenerate your 2242 configuration, then "service local_unbound reload" to load the 2243 new configuration. 2244 224520140709: 2246 The GNU texinfo and GNU info pages are not built and installed 2247 anymore, WITH_INFO knob has been added to allow to built and install 2248 them again. 2249 UPDATE: see 20150102 entry on texinfo's removal 2250 225120140708: 2252 The GNU readline library is now an INTERNALLIB - that is, it is 2253 statically linked into consumers (GDB and variants) in the base 2254 system, and the shared library is no longer installed. The 2255 devel/readline port is available for third party software that 2256 requires readline. 2257 225820140702: 2259 The Itanium architecture (ia64) has been removed from the list of 2260 known architectures. This is the first step in the removal of the 2261 architecture. 2262 226320140701: 2264 Commit r268115 has added NFSv4.1 server support, merged from 2265 projects/nfsv4.1-server. Since this includes changes to the 2266 internal interfaces between the NFS related modules, a full 2267 build of the kernel and modules will be necessary. 2268 __FreeBSD_version has been bumped. 2269 227020140629: 2271 The WITHOUT_VT_SUPPORT kernel config knob has been renamed 2272 WITHOUT_VT. (The other _SUPPORT knobs have a consistent meaning 2273 which differs from the behaviour controlled by this knob.) 2274 227520140619: 2276 Maximal length of the serial number in CTL was increased from 16 to 2277 64 chars, that breaks ABI. All CTL-related tools, such as ctladm 2278 and ctld, need to be rebuilt to work with a new kernel. 2279 228020140606: 2281 The libatf-c and libatf-c++ major versions were downgraded to 0 and 2282 1 respectively to match the upstream numbers. They were out of 2283 sync because, when they were originally added to FreeBSD, the 2284 upstream versions were not respected. These libraries are private 2285 and not yet built by default, so renumbering them should be a 2286 non-issue. However, unclean source trees will yield broken test 2287 programs once the operator executes "make delete-old-libs" after a 2288 "make installworld". 2289 2290 Additionally, the atf-sh binary was made private by moving it into 2291 /usr/libexec/. Already-built shell test programs will keep the 2292 path to the old binary so they will break after "make delete-old" 2293 is run. 2294 2295 If you are using WITH_TESTS=yes (not the default), wipe the object 2296 tree and rebuild from scratch to prevent spurious test failures. 2297 This is only needed once: the misnumbered libraries and misplaced 2298 binaries have been added to OptionalObsoleteFiles.inc so they will 2299 be removed during a clean upgrade. 2300 230120140512: 2302 Clang and llvm have been upgraded to 3.4.1 release. 2303 230420140508: 2305 We bogusly installed src.opts.mk in /usr/share/mk. This file should 2306 be removed to avoid issues in the future (and has been added to 2307 ObsoleteFiles.inc). 2308 230920140505: 2310 /etc/src.conf now affects only builds of the FreeBSD src tree. In the 2311 past, it affected all builds that used the bsd.*.mk files. The old 2312 behavior was a bug, but people may have relied upon it. To get this 2313 behavior back, you can .include /etc/src.conf from /etc/make.conf 2314 (which is still global and isn't changed). This also changes the 2315 behavior of incremental builds inside the tree of individual 2316 directories. Set MAKESYSPATH to ".../share/mk" to do that. 2317 Although this has survived make universe and some upgrade scenarios, 2318 other upgrade scenarios may have broken. At least one form of 2319 temporary breakage was fixed with MAKESYSPATH settings for buildworld 2320 as well... In cases where MAKESYSPATH isn't working with this 2321 setting, you'll need to set it to the full path to your tree. 2322 2323 One side effect of all this cleaning up is that bsd.compiler.mk 2324 is no longer implicitly included by bsd.own.mk. If you wish to 2325 use COMPILER_TYPE, you must now explicitly include bsd.compiler.mk 2326 as well. 2327 232820140430: 2329 The lindev device has been removed since /dev/full has been made a 2330 standard device. __FreeBSD_version has been bumped. 2331 233220140424: 2333 The knob WITHOUT_VI was added to the base system, which controls 2334 building ex(1), vi(1), etc. Older releases of FreeBSD required ex(1) 2335 in order to reorder files share/termcap and didn't build ex(1) as a 2336 build tool, so building/installing with WITH_VI is highly advised for 2337 build hosts for older releases. 2338 2339 This issue has been fixed in stable/9 and stable/10 in r277022 and 2340 r276991, respectively. 2341 234220140418: 2343 The YES_HESIOD knob has been removed. It has been obsolete for 2344 a decade. Please move to using WITH_HESIOD instead or your builds 2345 will silently lack HESIOD. 2346 234720140405: 2348 The uart(4) driver has been changed with respect to its handling 2349 of the low-level console. Previously the uart(4) driver prevented 2350 any process from changing the baudrate or the CLOCAL and HUPCL 2351 control flags. By removing the restrictions, operators can make 2352 changes to the serial console port without having to reboot. 2353 However, when getty(8) is started on the serial device that is 2354 associated with the low-level console, a misconfigured terminal 2355 line in /etc/ttys will now have a real impact. 2356 Before upgrading the kernel, make sure that /etc/ttys has the 2357 serial console device configured as 3wire without baudrate to 2358 preserve the previous behaviour. E.g: 2359 ttyu0 "/usr/libexec/getty 3wire" vt100 on secure 2360 236120140306: 2362 Support for libwrap (TCP wrappers) in rpcbind was disabled by default 2363 to improve performance. To re-enable it, if needed, run rpcbind 2364 with command line option -W. 2365 236620140226: 2367 Switched back to the GPL dtc compiler due to updates in the upstream 2368 dts files not being supported by the BSDL dtc compiler. You will need 2369 to rebuild your kernel toolchain to pick up the new compiler. Core dumps 2370 may result while building dtb files during a kernel build if you fail 2371 to do so. Set WITHOUT_GPL_DTC if you require the BSDL compiler. 2372 237320140216: 2374 Clang and llvm have been upgraded to 3.4 release. 2375 237620140216: 2377 The nve(4) driver has been removed. Please use the nfe(4) driver 2378 for NVIDIA nForce MCP Ethernet adapters instead. 2379 238020140212: 2381 An ABI incompatibility crept into the libc++ 3.4 import in r261283. 2382 This could cause certain C++ applications using shared libraries built 2383 against the previous version of libc++ to crash. The incompatibility 2384 has now been fixed, but any C++ applications or shared libraries built 2385 between r261283 and r261801 should be recompiled. 2386 238720140204: 2388 OpenSSH will now ignore errors caused by kernel lacking of Capsicum 2389 capability mode support. Please note that enabling the feature in 2390 kernel is still highly recommended. 2391 239220140131: 2393 OpenSSH is now built with sandbox support, and will use sandbox as 2394 the default privilege separation method. This requires Capsicum 2395 capability mode support in kernel. 2396 239720140128: 2398 The libelf and libdwarf libraries have been updated to newer 2399 versions from upstream. Shared library version numbers for 2400 these two libraries were bumped. Any ports or binaries 2401 requiring these two libraries should be recompiled. 2402 __FreeBSD_version is bumped to 1100006. 2403 240420140110: 2405 If a Makefile in a tests/ directory was auto-generating a Kyuafile 2406 instead of providing an explicit one, this would prevent such 2407 Makefile from providing its own Kyuafile in the future during 2408 NO_CLEAN builds. This has been fixed in the Makefiles but manual 2409 intervention is needed to clean an objdir if you use NO_CLEAN: 2410 # find /usr/obj -name Kyuafile | xargs rm -f 2411 241220131213: 2413 The behavior of gss_pseudo_random() for the krb5 mechanism 2414 has changed, for applications requesting a longer random string 2415 than produced by the underlying enctype's pseudo-random() function. 2416 In particular, the random string produced from a session key of 2417 enctype aes256-cts-hmac-sha1-96 or aes256-cts-hmac-sha1-96 will 2418 be different at the 17th octet and later, after this change. 2419 The counter used in the PRF+ construction is now encoded as a 2420 big-endian integer in accordance with RFC 4402. 2421 __FreeBSD_version is bumped to 1100004. 2422 242320131108: 2424 The WITHOUT_ATF build knob has been removed and its functionality 2425 has been subsumed into the more generic WITHOUT_TESTS. If you were 2426 using the former to disable the build of the ATF libraries, you 2427 should change your settings to use the latter. 2428 242920131025: 2430 The default version of mtree is nmtree which is obtained from 2431 NetBSD. The output is generally the same, but may vary 2432 slightly. If you found you need identical output adding 2433 "-F freebsd9" to the command line should do the trick. For the 2434 time being, the old mtree is available as fmtree. 2435 243620131014: 2437 libbsdyml has been renamed to libyaml and moved to /usr/lib/private. 2438 This will break ports-mgmt/pkg. Rebuild the port, or upgrade to pkg 2439 1.1.4_8 and verify bsdyml not linked in, before running "make 2440 delete-old-libs": 2441 # make -C /usr/ports/ports-mgmt/pkg build deinstall install clean 2442 or 2443 # pkg install pkg; ldd /usr/local/sbin/pkg | grep bsdyml 2444 244520131010: 2446 The stable/10 branch has been created in subversion from head 2447 revision r256279. 2448 2449COMMON ITEMS: 2450 2451 General Notes 2452 ------------- 2453 Sometimes, obscure build problems are the result of environment 2454 poisoning. This can happen because the make utility reads its 2455 environment when searching for values for global variables. To run 2456 your build attempts in an "environmental clean room", prefix all make 2457 commands with 'env -i '. See the env(1) manual page for more details. 2458 Occasionally a build failure will occur with "make -j" due to a race 2459 condition. If this happens try building again without -j, and please 2460 report a bug if it happens consistently. 2461 2462 When upgrading from one major version to another it is generally best to 2463 upgrade to the latest code in the currently installed branch first, then 2464 do an upgrade to the new branch. This is the best-tested upgrade path, 2465 and has the highest probability of being successful. Please try this 2466 approach if you encounter problems with a major version upgrade. Since 2467 the stable 4.x branch point, one has generally been able to upgrade from 2468 anywhere in the most recent stable branch to head / current (or even the 2469 last couple of stable branches). See the top of this file when there's 2470 an exception. 2471 2472 The update process will emit an error on an attempt to perform a build 2473 or install from a FreeBSD version below the earliest supported version. 2474 When updating from an older version the update should be performed one 2475 major release at a time, including running `make delete-old` at each 2476 step. 2477 2478 When upgrading a live system, having a root shell around before 2479 installing anything can help undo problems. Not having a root shell 2480 around can lead to problems if pam has changed too much from your 2481 starting point to allow continued authentication after the upgrade. 2482 2483 This file should be read as a log of events. When a later event changes 2484 information of a prior event, the prior event should not be deleted. 2485 Instead, a pointer to the entry with the new information should be 2486 placed in the old entry. Readers of this file should also sanity check 2487 older entries before relying on them blindly. Authors of new entries 2488 should write them with this in mind. 2489 2490 ZFS notes 2491 --------- 2492 When upgrading the boot ZFS pool to a new version, always follow 2493 these two steps: 2494 2495 1.) recompile and reinstall the ZFS boot loader and boot block 2496 (this is part of "make buildworld" and "make installworld") 2497 2498 2.) update the ZFS boot block on your boot drive 2499 2500 The following example updates the ZFS boot block on the 2501 freebsd-boot partition of a GPT partitioned drive ada0: 2502 "gpart bootcode -p /boot/gptzfsboot -i $N ada0" 2503 The value $N will typically be 1 (if booting from BIOS) or 2 (if 2504 booting from EFI). 2505 2506 Non-boot pools do not need these updates. 2507 2508 To build a kernel 2509 ----------------- 2510 If you are updating from a prior version of FreeBSD (even one just 2511 a few days old), you should follow this procedure. It is the most 2512 failsafe as it uses a /usr/obj tree with a fresh mini-buildworld, 2513 2514 make kernel-toolchain 2515 make -DALWAYS_CHECK_MAKE buildkernel KERNCONF=YOUR_KERNEL_HERE 2516 make -DALWAYS_CHECK_MAKE installkernel KERNCONF=YOUR_KERNEL_HERE 2517 2518 To test a kernel once 2519 --------------------- 2520 If you just want to boot a kernel once (because you are not sure 2521 if it works, or if you want to boot a known bad kernel to provide 2522 debugging information) run 2523 make installkernel KERNCONF=YOUR_KERNEL_HERE KODIR=/boot/testkernel 2524 nextboot -k testkernel 2525 2526 To rebuild everything and install it on the current system. 2527 ----------------------------------------------------------- 2528 # Note: sometimes if you are running current you gotta do more than 2529 # is listed here if you are upgrading from a really old current. 2530 2531 <make sure you have good level 0 dumps> 2532 make buildworld 2533 make buildkernel KERNCONF=YOUR_KERNEL_HERE 2534 make installkernel KERNCONF=YOUR_KERNEL_HERE 2535 [1] 2536 <reboot in single user> [3] 2537 etcupdate -p [5] 2538 make installworld 2539 etcupdate -B [4] 2540 make delete-old [6] 2541 <reboot> 2542 2543 To cross-install current onto a separate partition 2544 -------------------------------------------------- 2545 # In this approach we use a separate partition to hold 2546 # current's root, 'usr', and 'var' directories. A partition 2547 # holding "/", "/usr" and "/var" should be about 2GB in 2548 # size. 2549 2550 <make sure you have good level 0 dumps> 2551 <boot into -stable> 2552 make buildworld 2553 make buildkernel KERNCONF=YOUR_KERNEL_HERE 2554 <maybe newfs current's root partition> 2555 <mount current's root partition on directory ${CURRENT_ROOT}> 2556 make installworld DESTDIR=${CURRENT_ROOT} -DDB_FROM_SRC 2557 make distribution DESTDIR=${CURRENT_ROOT} # if newfs'd 2558 make installkernel KERNCONF=YOUR_KERNEL_HERE DESTDIR=${CURRENT_ROOT} 2559 cp /etc/fstab ${CURRENT_ROOT}/etc/fstab # if newfs'd 2560 <edit ${CURRENT_ROOT}/etc/fstab to mount "/" from the correct partition> 2561 <reboot into current> 2562 <do a "native" rebuild/install as described in the previous section> 2563 <maybe install compatibility libraries from ports/misc/compat*> 2564 <reboot> 2565 2566 2567 To upgrade in-place from stable to current 2568 ---------------------------------------------- 2569 <make sure you have good level 0 dumps> 2570 make buildworld [9] 2571 make buildkernel KERNCONF=YOUR_KERNEL_HERE [8] 2572 make installkernel KERNCONF=YOUR_KERNEL_HERE 2573 [1] 2574 <reboot in single user> [3] 2575 etcupdate -p [5] 2576 make installworld 2577 etcupdate -B [4] 2578 make delete-old [6] 2579 <reboot> 2580 2581 Make sure that you've read the UPDATING file to understand the 2582 tweaks to various things you need. At this point in the life 2583 cycle of current, things change often and you are on your own 2584 to cope. The defaults can also change, so please read ALL of 2585 the UPDATING entries. 2586 2587 Also, if you are tracking -current, you must be subscribed to 2588 freebsd-current@freebsd.org. Make sure that before you update 2589 your sources that you have read and understood all the recent 2590 messages there. If in doubt, please track -stable which has 2591 much fewer pitfalls. 2592 2593 [1] If you have third party modules, such as vmware, you should disable 2594 them at this point so they don't crash your system on 2595 reboot. Alternatively, you should rebuild all the modules you have in 2596 your system and install them as well. If you are running -current, you 2597 should seriously consider placing all sources to all the modules for 2598 your system (or symlinks to them) in /usr/local/sys/modules so this 2599 happens automatically. If all your modules come from ports, then adding 2600 the port origin directories to PORTS_MODULES instead is also automatic 2601 and effective, eg: 2602 PORTS_MODULES+=x11/nvidia-driver 2603 2604 [3] From the bootblocks, boot -s, and then do 2605 fsck -p 2606 mount -u / 2607 mount -a 2608 sh /etc/rc.d/zfs start # mount zfs filesystem, if needed 2609 cd src # full path to source 2610 adjkerntz -i # if CMOS is wall time 2611 Also, when doing a major release upgrade, it is required that you boot 2612 into single user mode to do the installworld. 2613 2614 [4] Note: This step is non-optional. Failure to do this step 2615 can result in a significant reduction in the functionality of the 2616 system. Attempting to do it by hand is not recommended and those 2617 that pursue this avenue should read this file carefully, as well 2618 as the archives of freebsd-current and freebsd-hackers mailing lists 2619 for potential gotchas. See etcupdate(8) for more information. 2620 2621 [5] Usually this step is a no-op. However, from time to time 2622 you may need to do this if you get unknown user in the following 2623 step. 2624 2625 [6] This only deletes old files and directories. Old libraries 2626 can be deleted by "make delete-old-libs", but you have to make 2627 sure that no program is using those libraries anymore. 2628 2629 [8] The new kernel must be able to run existing binaries used by an 2630 installworld. When upgrading across major versions, the new kernel's 2631 configuration must include the correct COMPAT_FREEBSD<n> option for 2632 existing binaries (e.g. COMPAT_FREEBSD11 to run 11.x binaries). Failure 2633 to do so may leave you with a system that is hard to boot to recover. A 2634 GENERIC kernel will include suitable compatibility options to run 2635 binaries from older branches. Note that the ability to run binaries 2636 from unsupported branches is not guaranteed. 2637 2638 Make sure that you merge any new devices from GENERIC since the 2639 last time you updated your kernel config file. Options also 2640 change over time, so you may need to adjust your custom kernels 2641 for these as well. 2642 2643 [9] If CPUTYPE is defined in your /etc/make.conf, make sure to use the 2644 "?=" instead of the "=" assignment operator, so that buildworld can 2645 override the CPUTYPE if it needs to. 2646 2647 MAKEOBJDIRPREFIX must be defined in an environment variable, and 2648 not on the command line, or in /etc/make.conf. buildworld will 2649 warn if it is improperly defined. 2650FORMAT: 2651 2652This file contains a list, in reverse chronological order, of major 2653breakages in tracking -current. It is not guaranteed to be a complete 2654list of such breakages, and only contains entries since September 23, 2011. 2655If you need to see UPDATING entries from before that date, you will need 2656to fetch an UPDATING file from an older FreeBSD release. 2657 2658Copyright information: 2659 2660Copyright 1998-2009 M.
