1Updating Information for FreeBSD current users. 2 3This file is maintained and copyrighted by M. Warner Losh <imp@freebsd.org>. 4See end of file for further details. For commonly done items, please see the 5COMMON ITEMS: section later in the file. These instructions assume that you 6basically know what you are doing. If not, then please consult the FreeBSD 7handbook: 8 9 https://docs.freebsd.org/en/books/handbook/cutting-edge/#makeworld 10 11Items affecting the ports and packages system can be found in 12/usr/ports/UPDATING. Please read that file before updating system packages 13and/or ports. 14 15NOTE TO PEOPLE WHO THINK THAT FreeBSD 14.x IS SLOW: 16 FreeBSD 14.x has many debugging features turned on, in both the kernel 17 and userland. These features attempt to detect incorrect use of 18 system primitives, and encourage loud failure through extra sanity 19 checking and fail stop semantics. They also substantially impact 20 system performance. If you want to do performance measurement, 21 benchmarking, and optimization, you'll want to turn them off. This 22 includes various WITNESS- related kernel options, INVARIANTS, malloc 23 debugging flags in userland, and various verbose features in the 24 kernel. Many developers choose to disable these features on build 25 machines to maximize performance. (To completely disable malloc 26 debugging, define WITH_MALLOC_PRODUCTION in /etc/src.conf and rebuild 27 world, or to merely disable the most expensive debugging functionality 28 at runtime, run "ln -s 'abort:false,junk:false' /etc/malloc.conf".) 29 3020211230: 31 The macros provided for the manipulation of CPU sets (e.g. CPU_AND) 32 have been modified to take 2 source arguments instead of only 1. 33 Externally maintained sources that use these macros will have to 34 be adapted. The FreeBSD version has been bumped to 1400046 to 35 reflect this change. 36 3720211214: 38 A number of the kernel include files are able to be included by 39 themselves. A test has been added to buildworld to enforce this. 40 4120211209: 42 Remove mips as a recognized target. This starts the decommissioning of 43 mips support in FreeBSD. mips related items will be removed wholesale in 44 the coming days and weeks. 45 46 This broke the NO_CLEAN build for some people. Either do a clean build 47 or touch 48 lib/clang/include/llvm/Config/Targets.def 49 lib/clang/include/llvm/Config/AsmParsers.def 50 lib/clang/include/llvm/Config/Disassemblers.def 51 lib/clang/include/llvm/Config/AsmPrinters.def 52 before the build to force everything to rebuild that needs to. 53 5420211202: 55 Unbound support for RFC8375: The special-use domain 'home.arpa' is 56 by default blocked. To unblock it use a local-zone nodefault 57 statement in unbound.conf: 58 local-zone: "home.arpa." nodefault 59 60 Or use another type of local-zone to override with your choice. 61 62 The reason for this is discussed in Section 6.1 of RFC8375: 63 Because 'home.arpa.' is not globally scoped and cannot be secured 64 using DNSSEC based on the root domain's trust anchor, there is no way 65 to tell, using a standard DNS query, in which homenet scope an answer 66 belongs. Consequently, users may experience surprising results with 67 such names when roaming to different homenets. 68 6920211110: 70 Commit b8d60729deef changed the TCP congestion control framework so 71 that any of the included congestion control modules could be 72 the single module built into the kernel. Previously newreno 73 was automatically built in through direct reference. As of 74 this commit you are required to declare at least one congestion 75 control module (e.g. 'options CC_NEWRENO') and to also declare a 76 default using the CC_DEFAULT option (e.g. options CC_DEFAULT="newreno\"). 77 The GENERIC configuration includes CC_NEWRENO and defines newreno 78 as the default. If no congestion control option is built into the 79 kernel and you are including networking, the kernel compile will 80 fail. Also if no default is declared the kernel compile will fail. 81 8220211118: 83 Mips has been removed from universe builds. It will be removed from the 84 tree shortly. 85 8620211106: 87 Commit f0c9847a6c47 changed the arguments for VOP_ALLOCATE. 88 The NFS modules must be rebuilt from sources and any out 89 of tree file systems that implement their own VOP_ALLOCATE 90 may need to be modified. 91 9220211022: 93 The synchronous PPP kernel driver sppp(4) has been removed. 94 The cp(4) and ce(4) drivers are now always compiled with netgraph(4) 95 support, formerly enabled by NETGRAPH_CRONYX option. 96 9720211020: 98 sh(1) is now the default shell for the root user. To force root to use 99 the csh shell, please run the following command as root: 100 101 # chsh -s csh 102 10320211004: 104 Ncurses distribution has been split between libtinfow and libncurses 105 with libncurses.so becoming a linker (ld) script to seamlessly link 106 to libtinfow as needed. Bump _FreeBSD_version to 1400035 to reflect 107 this change. 108 10920210923: 110 As of commit 8160a0f62be6, the dummynet module no longer depends on the 111 ipfw module. Dummynet can now be used by pf as well as ipfw. As such 112 users who relied on this dependency may need to include ipfw in the 113 list of modules to load on their systems. 114 11520210922: 116 As of commit 903873ce1560, the mixer(8) utility has got a slightly 117 new syntax. Please refer to the mixer(8) manual page for more 118 information. The old mixer utility can be installed from ports: 119 audio/freebsd-13-mixer 120 12120210911: 122 As of commit 55089ef4f8bb, the global variable nfs_maxcopyrange has 123 been deleted from the nfscommon.ko. As such, nfsd.ko must be built 124 from up to date sources to avoid an undefined reference when 125 being loaded. 126 12720210817: 128 As of commit 62ca9fc1ad56 OpenSSL no longer enables kernel TLS 129 by default. Users can enable kernel TLS via the "KTLS" SSL 130 option. This can be enabled globally by using a custom 131 OpenSSL config file via OPENSSL_CONF or via an 132 application-specific configuration option for applications 133 which permit setting SSL options via SSL_CONF_cmd(3). 134 13520210811: 136 Commit 3ad1e1c1ce20 changed the internal KAPI between the NFS 137 modules. Therefore, all need to be rebuilt from sources. 138 13920210730: 140 Commit b69019c14cd8 removes pf's DIOCGETSTATESNV ioctl. 141 As of be70c7a50d32 it is no longer used by userspace, but it does mean 142 users may not be able to enumerate pf states if they update the kernel 143 past b69019c14cd8 without first updating userspace past be70c7a50d32. 144 14520210729: 146 As of commit 01ad0c007964 if_bridge member interfaces can no longer 147 change their MTU. Changing the MTU of the bridge itself will change the 148 MTU on all member interfaces instead. 149 15020210716: 151 Commit ee29e6f31111 changed the internal KAPI between the nfscommon 152 and nfsd modules. Therefore, both need to be rebuilt from sources. 153 Bump __FreeBSD_version to 1400026 for this KAPI change. 154 15520210715: 156 The 20210707 awk update brought in a change in behavior. This has 157 been corrected as of d4d252c49976. Between these dates, if you 158 installed a new awk binary, you may not be able to build a new 159 kernel because the change in behavior affected the genoffset 160 script used to build the kernel. If you did update, the fix is 161 to update your sources past the above hash and do 162 % cd usr.bin/awk 163 % make clean all 164 % sudo -E make install 165 to enable building kernels again. 166 16720210708: 168 Commit 1e0a518d6548 changed the internal KAPI between the NFS 169 modules. They all need to be rebuilt from sources. I did not 170 bump __FreeBSD_version, since it was bumped recently. 171 17220210707: 173 awk has been updated to the latest one-true-awk version 20210215. 174 This contains a number of minor bug fixes. 175 17620210624: 177 The NFSv4 client now uses the highest minor version of NFSv4 178 supported by the NFSv4 server by default instead of minor version 0, 179 for NFSv4 mounts. 180 The "minorversion" mount option may be used to override this default. 181 18220210618: 183 Bump __FreeBSD_version to 1400024 for LinuxKPI changes. 184 Most notably netdev.h can change now as the (last) dependencies 185 (mlx4/ofed) are now using struct ifnet directly, but also for PCI 186 additions and others. 187 18820210618: 189 The directory "blacklisted" under /usr/share/certs/ has been 190 renamed to "untrusted". 191 19220210611: 193 svnlite has been removed from base. Should you need svn for any reason 194 please install the svn package or port. 195 19620210611: 197 Commit e1a907a25cfa changed the internal KAPI between the krpc 198 and nfsserver. As such, both modules must be rebuilt from 199 sources. Bump __FreeBSD_version to 1400022. 200 20120210610: 202 The an(4) driver has been removed from FreeBSD. 203 20420210608: 205 The vendor/openzfs branch was renamed to vendor/openzfs/legacy to 206 start tracking OpenZFS upstream more closely. Please see 207https://lists.freebsd.org/archives/freebsd-current/2021-June/000153.html 208 for details on how to correct any errors that might result. The 209 short version is that you need to remove the old branch locally: 210 git update-ref -d refs/remotes/freebsd/vendor/openzfs 211 (assuming your upstream origin is named 'freebsd'). 212 21320210525: 214 Commits 17accc08ae15 and de102f870501 add new files to LinuxKPI 215 which break drm-kmod. In addition various other additions where 216 committed. Bump __FreeBSD_version to 1400015 to be able to 217 detect this. 218 21920210513: 220 Commit ca179c4d74f2 changed the package in which the OpenSSL 221 libraries and utilities are packaged. 222 It is recommended for pkgbase user to do: 223 pkg install -f FreeBSD-openssl 224 before pkg upgrade otherwise some dependencies might not be met 225 and pkg will stop working as libssl will not be present anymore 226 on the system. 227 22820210426: 229 Commit 875977314881 changed the internal KAPI between 230 the nfsd and nfscommon modules. As such these modules 231 need to be rebuilt from sources. 232 Without this patch in your NFSv4.1/4.2 server, enabling 233 delegations by setting vfs.nfsd.issue_delegations non-zero 234 is not recommended. 235 23620210411: 237 Commit 7763814fc9c2 changed the internal KAPI between 238 the krpc and NFS. As such, the krpc, nfscommon and 239 nfscl modules must all be rebuilt from sources. 240 Without this patch, NFSv4.1/4.2 mounts should not 241 be done with the nfscbd(8) daemon running, to avoid 242 needing a working back channel for server->client RPCs. 243 24420210330: 245 Commit 01ae8969a9ee fixed the NFSv4.1/4.2 server so that it 246 handles binding of the back channel as required by RFC5661. 247 Until this patch is in your server, avoid use of the "nconnects" 248 mount option for Linux NFSv4.1/4.2 mounts. 249 25020210225: 251 For 64-bit architectures the base system is now built with Position 252 Independent Executable (PIE) support enabled by default. It may be 253 disabled using the WITHOUT_PIE knob. A clean build is required. 254 25520210128: 256 Various LinuxKPI functionality was added which conflicts with DRM. 257 Please update your drm-kmod port to after the __FreeBSD_version 1400003 258 update. 259 26020210108: 261 PC Card attachments for all devices have been removed. In the case of 262 wi and cmx, the entire drivers were removed because they were only 263 PC Card devices. FreeBSD_version 1300134 should be used for this 264 since it was bumped so recently. 265 26620210107: 267 Transport-independent parts of HID support have been split off the USB 268 code in to separate subsystem. Kernel configs which include one of 269 ums, ukbd, uhid, atp, wsp, wmt, uaudio, ugold or ucycom drivers should 270 be updated with adding of "device hid" line. 271 27220210105: 273 ncurses installation has been modified to only keep the widechar 274 enabled version. Incremental build is broken for that change, so it 275 requires a clean build. 276 27720201223: 278 The FreeBSD project has migrated from Subversion to Git. Temporary 279 instructions can be found at 280 https://github.com/bsdimp/freebsd-git-docs/blob/main/src-cvt.md 281 and other documents in that repo. 282 28320201216: 284 The services database has been updated to cover more of the basic 285 services expected in a modern system. The database is big enough 286 that it will cause issues in mergemaster in Releases previous to 287 12.2 and 11.3, or in very old current systems from before r358154. 288 28920201215: 290 Obsolete in-tree GDB 6.1.1 has been removed. GDB (including kgdb) 291 may be installed from ports or packages. 292 29320201124: 294 ping6 has been merged into ping. It can now be called as "ping -6". 295 See ping(8) for details. 296 29720201108: 298 Default value of net.add_addr_allfibs has been changed to 0. 299 If you have multi-fib configuration and rely on existence of all 300 interface routes in every fib, you need to set the above sysctl to 1. 301 30220201030: 303 The internal pre-processor in the calendar(1) program has been 304 extended to support more C pre-processor commands (e.g. #ifdef, #else, 305 and #undef) and to detect unbalanced conditional statements. 306 Error messages have been extended to include the filename and line 307 number if processing stops to help fixing malformed data files. 308 30920201026: 310 All the data files for the calendar(1) program, except calendar.freebsd, 311 have been moved to the deskutils/calendar-data port, much like the 312 jewish calendar entries were moved to deskutils/hebcal years ago. After 313 make delete-old-files, you need to install it to retain full 314 functionality. calendar(1) will issue a reminder for files it can't 315 find. 316 31720200923: 318 LINT files are no longer generated. We now include the relevant NOTES 319 files. Note: This may cause conflicts with updating in some cases. 320 find sys -name LINT\* -delete 321 is suggested across this commit to remove the generated LINT files. 322 323 If you have tried to update with generated files there, the svn 324 command you want to un-auger the tree is 325 cd sys/amd64/conf 326 svn revert -R . 327 and then do the above find from the top level. Substitute 'amd64' 328 above with where the error message indicates a conflict. 329 33020200824: 331 OpenZFS support has been integrated. Do not upgrade root pools until 332 the loader is updated to support zstd. Furthermore, we caution against 333 'zpool upgrade' for the next few weeks. The change should be transparent 334 unless you want to use new features. 335 336 Not all "NO_CLEAN" build scenarios work across these changes. Many 337 scenarios have been tested and fixed, but rebuilding kernels without 338 rebuilding world may fail. 339 340 The ZFS cache file has moved from /boot to /etc to match the OpenZFS 341 upstream default. A fallback to /boot has been added for mountroot. 342 343 Pool auto import behavior at boot has been moved from the kernel module 344 to an explicit "zpool import -a" in one of the rc scripts enabled by 345 zfs_enable=YES. This means your non-root zpools won't auto import until 346 you upgrade your /etc/rc.d files. 347 34820200824: 349 The resume code now notifies devd with the 'kernel' system 350 rather than the old 'kern' subsystem to be consistent with 351 other use. The old notification will be created as well, but 352 will be removed prior to FreeBSD 14.0. 353 35420200821: 355 r362275 changed the internal API between the kernel RPC and the 356 NFS modules. As such, all the modules must be recompiled from 357 sources. 358 35920200817: 360 r364330 modified the internal API used between the NFS modules. 361 As such, all the NFS modules must be re-compiled from sources. 362 36320200816: 364 Clang, llvm, lld, lldb, compiler-rt, libc++, libunwind and openmp have 365 been upgraded to 11.0.0. Please see the 20141231 entry below for 366 information about prerequisites and upgrading, if you are not already 367 using clang 3.5.0 or higher. 368 36920200810: 370 r364092 modified the internal ABI used between the kernel NFS 371 modules. As such, all of these modules need to be rebuilt 372 from sources, so a version bump was done. 373 37420200807: 375 Makefile.inc has been updated to work around the issue documented in 376 20200729. It was a case where the optimization of using symbolic links 377 to point to binaries created a situation where we'd run new binaries 378 with old libraries starting midway through the installworld process. 379 38020200729: 381 r363679 has redefined some undefined behavior in regcomp(3); notably, 382 extraneous escapes of most ordinary characters will no longer be 383 accepted. An exp-run has identified all of the problems with this in 384 ports, but other non-ports software may need extra escapes removed to 385 continue to function. 386 387 Because of this change, installworld may encounter the following error 388 from rtld: Undefined symbol "regcomp@FBSD_1.6" -- It is imperative that 389 you do not halt installworld. Instead, let it run to completion (whether 390 successful or not) and run installworld once more. 391 39220200627: 393 A new implementation of bc and dc has been imported in r362681. This 394 implementation corrects non-conformant behavior of the previous bc 395 and adds GNU bc compatible options. It offers a number of extensions, 396 is much faster on large values, and has support for message catalogs 397 (a number of languages are already supported, contributions of further 398 languages welcome). The option WITHOUT_GH_BC can be used to build the 399 world with the previous versions of bc and dc. 400 40120200625: 402 r362639 changed the internal API used between the NFS kernel modules. 403 As such, they all need to be rebuilt from sources. 404 40520200613: 406 r362158 changed the arguments for VFS_CHECKEXP(). As such, any 407 out of tree file systems need to be modified and rebuilt. 408 Also, any file systems that are modules must be rebuilt. 409 41020200604: 411 read(2) of a directory fd is now rejected by default. root may 412 re-enable it for system root only on non-ZFS filesystems with the 413 security.bsd.allow_read_dir sysctl(8) MIB if 414 security.bsd.suser_enabled=1. 415 416 It may be advised to setup aliases for grep to default to `-d skip` if 417 commonly non-recursively grepping a list that includes directories and 418 the potential for the resulting stderr output is not tolerable. Example 419 aliases are now installed, commented out, in /root/.cshrc and 420 /root/.shrc. 421 42220200523: 423 Clang, llvm, lld, lldb, compiler-rt, libc++, libunwind and openmp have 424 been upgraded to 10.0.1. Please see the 20141231 entry below for 425 information about prerequisites and upgrading, if you are not already 426 using clang 3.5.0 or higher. 427 42820200512: 429 Support for obsolete compilers has been removed from the build system. 430 Clang 6 and GCC 6.4 are the minimum supported versions. 431 43220200424: 433 closefrom(2) has been moved under COMPAT12, and replaced in libc with a 434 stub that calls close_range(2). If using a custom kernel configuration, 435 you may want to ensure that the COMPAT_FREEBSD12 option is included, as 436 a slightly older -CURRENT userland and older FreeBSD userlands may not 437 be functional without closefrom(2). 438 43920200414: 440 Upstream DTS from Linux 5.6 was merged and they now have the SID 441 and THS (Secure ID controller and THermal Sensor) node present. 442 The DTB overlays have now been removed from the tree for the H3/H5 and 443 A64 SoCs and the aw_sid and aw_thermal driver have been updated to 444 deal with upstream DTS. If you are using those overlays you need to 445 remove them from loader.conf and update the DTBs on the FAT partition. 446 44720200310: 448 Clang, llvm, lld, lldb, compiler-rt, libc++, libunwind and openmp have 449 been upgraded to 10.0.0. Please see the 20141231 entry below for 450 information about prerequisites and upgrading, if you are not already 451 using clang 3.5.0 or higher. 452 45320200309: 454 The amd(8) automount daemon has been removed from the source tree. 455 As of FreeBSD 10.1 autofs(5) is the preferred tool for automounting. 456 amd is still available in the sysutils/am-utils port. 457 45820200301: 459 Removed brooktree driver (bktr.4) from the tree. 460 46120200229: 462 The WITH_GPL_DTC option has been removed. The BSD-licenced device tree 463 compiler in usr.bin/dtc is used on all architectures which use dtc, and 464 the GPL dtc is available (if needed) from the sysutils/dtc port. 465 46620200229: 467 The WITHOUT_LLVM_LIBUNWIND option has been removed. LLVM's libunwind 468 is used by all supported CPU architectures. 469 47020200229: 471 GCC 4.2.1 has been removed from the tree. The WITH_GCC, 472 WITH_GCC_BOOTSTRAP, and WITH_GNUCXX options are no longer available. 473 Users who wish to build FreeBSD with GCC must use the external toolchain 474 ports or packages. 475 47620200220: 477 ncurses has been updated to a newer version (6.2-20200215). Given the ABI 478 has changed, users will have to rebuild all the ports that are linked to 479 ncurses. 480 48120200217: 482 The size of struct vnet and the magic cookie have changed. 483 Users need to recompile libkvm and all modules using VIMAGE 484 together with their new kernel. 485 48620200212: 487 Defining the long deprecated NO_CTF, NO_DEBUG_FILES, NO_INSTALLLIB, 488 NO_MAN, NO_PROFILE, and NO_WARNS variables is now an error. Update 489 your Makefiles and scripts to define MK_<var>=no instead as required. 490 491 One exception to this is that program or library Makefiles should 492 define MAN to empty rather than setting MK_MAN=no. 493 49420200108: 495 Clang/LLVM is now the default compiler and LLD the default 496 linker for riscv64. 497 49820200107: 499 make universe no longer uses GCC 4.2.1 on any architectures. 500 Architectures not supported by in-tree Clang/LLVM require an 501 external toolchain package. 502 50320200104: 504 GCC 4.2.1 is now not built by default, as part of the GCC 4.2.1 505 retirement plan. Specifically, the GCC, GCC_BOOTSTRAP, and GNUCXX 506 options default to off for all supported CPU architectures. As a 507 short-term transition aid they may be enabled via WITH_* options. 508 GCC 4.2.1 is expected to be removed from the tree on 2020-03-31. 509 51020200102: 511 Support for armv5 has been disconnected and is being removed. The 512 machine combination MACHINE=arm MACHINE_ARCH=arm is no longer valid. 513 You must now use a MACHINE_ARCH of armv6 or armv7. The default 514 MACHINE_ARCH for MACHINE=arm is now armv7. 515 51620191226: 517 Clang/LLVM is now the default compiler for all powerpc architectures. 518 LLD is now the default linker for powerpc64. The change for powerpc64 519 also includes a change to the ELFv2 ABI, incompatible with the existing 520 ABI. 521 52220191226: 523 Kernel-loadable random(4) modules are no longer unloadable. 524 52520191222: 526 Clang, llvm, lld, lldb, compiler-rt, libc++, libunwind and openmp have 527 been upgraded to 9.0.1. Please see the 20141231 entry below for 528 information about prerequisites and upgrading, if you are not already 529 using clang 3.5.0 or higher. 530 53120191212: 532 r355677 has modified the internal interface used between the 533 NFS modules in the kernel. As such, they must all be upgraded 534 simultaneously. I will do a version bump for this. 535 53620191205: 537 The root certificates of the Mozilla CA Certificate Store have been 538 imported into the base system and can be managed with the certctl(8) 539 utility. If you have installed the security/ca_root_nss port or package 540 with the ETCSYMLINK option (the default), be advised that there may be 541 differences between those included in the port and those included in 542 base due to differences in nss branch used as well as general update 543 frequency. Note also that certctl(8) cannot manage certs in the 544 format used by the security/ca_root_nss port. 545 54620191120: 547 The amd(8) automount daemon has been disabled by default, and will be 548 removed in the future. As of FreeBSD 10.1 the autofs(5) is available 549 for automounting. 550 55120191107: 552 The nctgpio and wbwd drivers have been moved to the superio bus. 553 If you have one of these drivers in a kernel configuration, then 554 you should add device superio to it. If you use one of these drivers 555 as a module and you compile a custom set of modules, then you should 556 add superio to the set. 557 55820191021: 559 KPIs for network drivers to access interface addresses have changed. 560 Users need to recompile NIC driver modules together with kernel. 561 56220191021: 563 The net.link.tap.user_open sysctl no longer prevents user opening of 564 already created /dev/tapNN devices. Access is still controlled by 565 node permissions, just like tun devices. The net.link.tap.user_open 566 sysctl is now used only to allow users to perform devfs cloning of 567 tap devices, and the subsequent open may not succeed if the user is not 568 in the appropriate group. This sysctl may be deprecated/removed 569 completely in the future. 570 57120191009: 572 mips, powerpc, and sparc64 are no longer built as part of 573 universe / tinderbox unless MAKE_OBSOLETE_GCC is defined. If 574 not defined, mips, powerpc, and sparc64 builds will look for 575 the xtoolchain binaries and if installed use them for universe 576 builds. As llvm 9.0 becomes vetted for these architectures, they 577 will be removed from the list. 578 57920191009: 580 Clang, llvm, lld, lldb, compiler-rt, libc++, libunwind and openmp have 581 been upgraded to 9.0.0. Please see the 20141231 entry below for 582 information about prerequisites and upgrading, if you are not already 583 using clang 3.5.0 or higher. 584 58520191003: 586 The hpt27xx, hptmv, hptnr, and hptrr drivers have been removed from 587 GENERIC. They are available as modules and can be loaded by adding 588 to /boot/loader.conf hpt27xx_load="YES", hptmv_load="YES", 589 hptnr_load="YES", or hptrr_load="YES", respectively. 590 59120190913: 592 ntpd no longer by default locks its pages in memory, allowing them 593 to be paged out by the kernel. Use rlimit memlock to restore 594 historic BSD behaviour. For example, add "rlimit memlock 32" 595 to ntp.conf to lock up to 32 MB of ntpd address space in memory. 596 59720190823: 598 Several of ping6's options have been renamed for better consistency 599 with ping. If you use any of -ARWXaghmrtwx, you must update your 600 scripts. See ping6(8) for details. 601 60220190727: 603 The vfs.fusefs.sync_unmount and vfs.fusefs.init_backgrounded sysctls 604 and the "-o sync_unmount" and "-o init_backgrounded" mount options have 605 been removed from mount_fusefs(8). You can safely remove them from 606 your scripts, because they had no effect. 607 608 The vfs.fusefs.fix_broken_io, vfs.fusefs.sync_resize, 609 vfs.fusefs.refresh_size, vfs.fusefs.mmap_enable, 610 vfs.fusefs.reclaim_revoked, and vfs.fusefs.data_cache_invalidate 611 sysctls have been removed. If you felt the need to set any of them to 612 a non-default value, please tell asomers@FreeBSD.org why. 613 61420190713: 615 Default permissions on the /var/account/acct file (and copies of it 616 rotated by periodic daily scripts) are changed from 0644 to 0640 617 because the file contains sensitive information that should not be 618 world-readable. If the /var/account directory must be created by 619 rc.d/accounting, the mode used is now 0750. Admins who use the 620 accounting feature are encouraged to change the mode of an existing 621 /var/account directory to 0750 or 0700. 622 62320190620: 624 Entropy collection and the /dev/random device are no longer optional 625 components. The "device random" option has been removed. 626 Implementations of distilling algorithms can still be made loadable 627 with "options RANDOM_LOADABLE" (e.g., random_fortuna.ko). 628 62920190612: 630 Clang, llvm, lld, lldb, compiler-rt, libc++, libunwind and openmp have 631 been upgraded to 8.0.1. Please see the 20141231 entry below for 632 information about prerequisites and upgrading, if you are not already 633 using clang 3.5.0 or higher. 634 63520190608: 636 A fix was applied to i386 kernel modules to avoid panics with 637 dpcpu or vnet. Users need to recompile i386 kernel modules 638 having pcpu or vnet sections or they will refuse to load. 639 64020190513: 641 User-wired pages now have their own counter, 642 vm.stats.vm.v_user_wire_count. The vm.max_wired sysctl was renamed 643 to vm.max_user_wired and changed from an unsigned int to an unsigned 644 long. bhyve VMs wired with the -S are now subject to the user 645 wiring limit; the vm.max_user_wired sysctl may need to be tuned to 646 avoid running into the limit. 647 64820190507: 649 The IPSEC option has been removed from GENERIC. Users requiring 650 ipsec(4) must now load the ipsec(4) kernel module. 651 65220190507: 653 The tap(4) driver has been folded into tun(4), and the module has been 654 renamed to tuntap. You should update any kld_list="if_tap" or 655 kld_list="if_tun" entries in /etc/rc.conf, if_tap_load="YES" or 656 if_tun_load="YES" entries in /boot/loader.conf to load the if_tuntap 657 module instead, and "device tap" or "device tun" entries in kernel 658 config files to select the tuntap device instead. 659 66020190418: 661 The following knobs have been added related to tradeoffs between 662 safe use of the random device and availability in the absence of 663 entropy: 664 665 kern.random.initial_seeding.bypass_before_seeding: tunable; set 666 non-zero to bypass the random device prior to seeding, or zero to 667 block random requests until the random device is initially seeded. 668 For now, set to 1 (unsafe) by default to restore pre-r346250 boot 669 availability properties. 670 671 kern.random.initial_seeding.read_random_bypassed_before_seeding: 672 read-only diagnostic sysctl that is set when bypass is enabled and 673 read_random(9) is bypassed, to enable programmatic handling of this 674 initial condition, if desired. 675 676 kern.random.initial_seeding.arc4random_bypassed_before_seeding: 677 Similar to the above, but for arc4random(9) initial seeding. 678 679 kern.random.initial_seeding.disable_bypass_warnings: tunable; set 680 non-zero to disable warnings in dmesg when the same conditions are 681 met as for the diagnostic sysctls above. Defaults to zero, i.e., 682 produce warnings in dmesg when the conditions are met. 683 68420190416: 685 The loadable random module KPI has changed; the random_infra_init() 686 routine now requires a 3rd function pointer for a bool (*)(void) 687 method that returns true if the random device is seeded (and 688 therefore unblocked). 689 69020190404: 691 r345895 reverts r320698. This implies that an nfsuserd(8) daemon 692 built from head sources between r320757 (July 6, 2017) and 693 r338192 (Aug. 22, 2018) will not work unless the "-use-udpsock" 694 is added to the command line. 695 nfsuserd daemons built from head sources that are post-r338192 are 696 not affected and should continue to work. 697 69820190320: 699 The fuse(4) module has been renamed to fusefs(4) for consistency with 700 other filesystems. You should update any kld_load="fuse" entries in 701 /etc/rc.conf, fuse_load="YES" entries in /boot/loader.conf, and 702 "options FUSE" entries in kernel config files. 703 70420190304: 705 Clang, llvm, lld, lldb, compiler-rt and libc++ have been upgraded to 706 8.0.0. Please see the 20141231 entry below for information about 707 prerequisites and upgrading, if you are not already using clang 3.5.0 708 or higher. 709 71020190226: 711 geom_uzip(4) depends on the new module xz. If geom_uzip is statically 712 compiled into your custom kernel, add 'device xz' statement to the 713 kernel config. 714 71520190219: 716 drm and drm2 have been removed from the tree. Please see 717 https://wiki.freebsd.org/Graphics for the latest information on 718 migrating to the drm ports. 719 72020190131: 721 Iflib is no longer unconditionally compiled into the kernel. Drivers 722 using iflib and statically compiled into the kernel, now require 723 the 'device iflib' config option. For the same drivers loaded as 724 modules on kernels not having 'device iflib', the iflib.ko module 725 is loaded automatically. 726 72720190125: 728 The IEEE80211_AMPDU_AGE and AH_SUPPORT_AR5416 kernel configuration 729 options no longer exist since r343219 and r343427 respectively; 730 nothing uses them, so they should be just removed from custom 731 kernel config files. 732 73320181230: 734 r342635 changes the way efibootmgr(8) works by requiring users to add 735 the -b (bootnum) parameter for commands where the bootnum was previously 736 specified with each option. For example 'efibootmgr -B 0001' is now 737 'efibootmgr -B -b 0001'. 738 73920181220: 740 r342286 modifies the NFSv4 server so that it obeys vfs.nfsd.nfs_privport 741 in the same as it is applied to NFSv2 and 3. This implies that NFSv4 742 servers that have vfs.nfsd.nfs_privport set will only allow mounts 743 from clients using a reserved port. Since both the FreeBSD and Linux 744 NFSv4 clients use reserved ports by default, this should not affect 745 most NFSv4 mounts. 746 74720181219: 748 The XLP config has been removed. We can't support 64-bit atomics in this 749 kernel because it is running in 32-bit mode. XLP users must transition 750 to running a 64-bit kernel (XLP64 or XLPN32). 751 752 The mips GXEMUL support has been removed from FreeBSD. MALTA* + qemu is 753 the preferred emulator today and we don't need two different ones. 754 755 The old sibyte / swarm / Broadcom BCM1250 support has been 756 removed from the mips port. 757 75820181211: 759 Clang, llvm, lld, lldb, compiler-rt and libc++ have been upgraded to 760 7.0.1. Please see the 20141231 entry below for information about 761 prerequisites and upgrading, if you are not already using clang 3.5.0 762 or higher. 763 76420181211: 765 Remove the timed and netdate programs from the base tree. Setting 766 the time with these daemons has been obsolete for over a decade. 767 76820181126: 769 On amd64, arm64 and armv7 (architectures that install LLVM's ld.lld 770 linker as /usr/bin/ld) GNU ld is no longer installed as ld.bfd, as 771 it produces broken binaries when ifuncs are in use. Users needing 772 GNU ld should install the binutils port or package. 773 77420181123: 775 The BSD crtbegin and crtend code has been enabled by default. It has 776 had extensive testing on amd64, arm64, and i386. It can be disabled 777 by building a world with -DWITHOUT_BSD_CRTBEGIN. 778 77920181115: 780 The set of CTM commands (ctm, ctm_smail, ctm_rmail, ctm_dequeue) 781 has been converted to a port (misc/ctm) and will be removed from 782 FreeBSD-13. It is available as a package (ctm) for all supported 783 FreeBSD versions. 784 78520181110: 786 The default newsyslog.conf(5) file has been changed to only include 787 files in /etc/newsyslog.conf.d/ and /usr/local/etc/newsyslog.conf.d/ if 788 the filenames end in '.conf' and do not begin with a '.'. 789 790 You should check the configuration files in these two directories match 791 this naming convention. You can verify which configuration files are 792 being included using the command: 793 $ newsyslog -Nrv 794 79520181015: 796 Ports for the DRM modules have been simplified. Now, amd64 users should 797 just install the drm-kmod port. All others should install 798 drm-legacy-kmod. 799 800 Graphics hardware that's newer than about 2010 usually works with 801 drm-kmod. For hardware older than 2013, however, some users will need 802 to use drm-legacy-kmod if drm-kmod doesn't work for them. Hardware older 803 than 2008 usually only works in drm-legacy-kmod. The graphics team can 804 only commit to hardware made since 2013 due to the complexity of the 805 market and difficulty to test all the older cards effectively. If you 806 have hardware supported by drm-kmod, you are strongly encouraged to use 807 that as you will get better support. 808 809 Other than KPI chasing, drm-legacy-kmod will not be updated. As outlined 810 elsewhere, the drm and drm2 modules will be eliminated from the src base 811 soon (with a limited exception for arm). Please update to the package 812 asap and report any issues to x11@freebsd.org. 813 814 Generally, anybody using the drm*-kmod packages should add 815 WITHOUT_DRM_MODULE=t and WITHOUT_DRM2_MODULE=t to avoid nasty 816 cross-threading surprises, especially with automatic driver 817 loading from X11 startup. These will become the defaults in 13-current 818 shortly. 819 82020181012: 821 The ixlv(4) driver has been renamed to iavf(4). As a consequence, 822 custom kernel and module loading configuration files must be updated 823 accordingly. Moreover, interfaces previous presented as ixlvN to the 824 system are now exposed as iavfN and network configuration files must 825 be adjusted as necessary. 826 82720181009: 828 OpenSSL has been updated to version 1.1.1. This update included 829 additional various API changes throughout the base system. It is 830 important to rebuild third-party software after upgrading. The value 831 of __FreeBSD_version has been bumped accordingly. 832 83320181006: 834 The legacy DRM modules and drivers have now been added to the loader's 835 module blacklist, in favor of loading them with kld_list in rc.conf(5). 836 The module blacklist may be overridden with the loader.conf(5) 837 'module_blacklist' variable, but loading them via rc.conf(5) is strongly 838 encouraged. 839 84020181002: 841 The cam(4) based nda(4) driver will be used over nvd(4) by default on 842 powerpc64. You may set 'options NVME_USE_NVD=1' in your kernel conf or 843 loader tunable 'hw.nvme.use_nvd=1' if you wish to use the existing 844 driver. Make sure to edit /boot/etc/kboot.conf and fstab to use the 845 nda device name. 846 84720180913: 848 Reproducible build mode is now on by default, in preparation for 849 FreeBSD 12.0. This eliminates build metadata such as the user, 850 host, and time from the kernel (and uname), unless the working tree 851 corresponds to a modified checkout from a version control system. 852 The previous behavior can be obtained by setting the /etc/src.conf 853 knob WITHOUT_REPRODUCIBLE_BUILD. 854 85520180826: 856 The Yarrow CSPRNG has been removed from the kernel as it has not been 857 supported by its designers since at least 2003. Fortuna has been the 858 default since FreeBSD-11. 859 86020180822: 861 devctl freeze/thaw have gone into the tree, the rc scripts have been 862 updated to use them and devmatch has been changed. You should update 863 kernel, userland and rc scripts all at the same time. 864 86520180818: 866 The default interpreter has been switched from 4th to Lua. 867 LOADER_DEFAULT_INTERP, documented in build(7), will override the default 868 interpreter. If you have custom FORTH code you will need to set 869 LOADER_DEFAULT_INTERP=4th (valid values are 4th, lua or simp) in 870 src.conf for the build. This will create default hard links between 871 loader and loader_4th instead of loader and loader_lua, the new default. 872 If you are using UEFI it will create the proper hard link to loader.efi. 873 874 bhyve uses userboot.so. It remains 4th-only until some issues are solved 875 regarding coexisting with multiple versions of FreeBSD are resolved. 876 87720180815: 878 ls(1) now respects the COLORTERM environment variable used in other 879 systems and software to indicate that a colored terminal is both 880 supported and desired. If ls(1) is suddenly emitting colors, they may 881 be disabled again by either removing the unwanted COLORTERM from your 882 environment, or using `ls --color=never`. The ls(1) specific CLICOLOR 883 may not be observed in a future release. 884 88520180808: 886 The default pager for most commands has been changed to "less". To 887 restore the old behavior, set PAGER="more" and MANPAGER="more -s" in 888 your environment. 889 89020180731: 891 The jedec_ts(4) driver has been removed. A superset of its functionality 892 is available in the jedec_dimm(4) driver, and the manpage for that 893 driver includes migration instructions. If you have "device jedec_ts" 894 in your kernel configuration file, it must be removed. 895 89620180730: 897 amd64/GENERIC now has EFI runtime services, EFIRT, enabled by default. 898 This should have no effect if the kernel is booted via BIOS/legacy boot. 899 EFIRT may be disabled via a loader tunable, efi.rt.disabled, if a system 900 has a buggy firmware that prevents a successful boot due to use of 901 runtime services. 902 90320180727: 904 Atmel AT91RM9200 and AT91SAM9, Cavium CNS 11xx and XScale 905 support has been removed from the tree. These ports were 906 obsolete and/or known to be broken for many years. 907 90820180723: 909 loader.efi has been augmented to participate more fully in the 910 UEFI boot manager protocol. loader.efi will now look at the 911 BootXXXX environment variable to determine if a specific kernel 912 or root partition was specified. XXXX is derived from BootCurrent. 913 efibootmgr(8) manages these standard UEFI variables. 914 91520180720: 916 zfsloader's functionality has now been folded into loader. 917 zfsloader is no longer necessary once you've updated your 918 boot blocks. For a transition period, we will install a 919 hardlink for zfsloader to loader to allow a smooth transition 920 until the boot blocks can be updated (hard link because old 921 zfs boot blocks don't understand symlinks). 922 92320180719: 924 ARM64 now have efifb support, if you want to have serial console 925 on your arm64 board when an screen is connected and the bootloader 926 setup a frame buffer for us to use, just add : 927 boot_serial=YES 928 boot_multicons=YES 929 in /boot/loader.conf 930 For Raspberry Pi 3 (RPI) users, this is needed even if you don't have 931 an screen connected as the firmware will setup a frame buffer are that 932 u-boot will expose as an EFI frame buffer. 933 93420180719: 935 New uid:gid added, ntpd:ntpd (123:123). Be sure to run mergemaster 936 or take steps to update /etc/passwd before doing installworld on 937 existing systems. Do not skip the "mergemaster -Fp" step before 938 installworld, as described in the update procedures near the bottom 939 of this document. Also, rc.d/ntpd now starts ntpd(8) as user ntpd 940 if the new mac_ntpd(4) policy is available, unless ntpd_flags or 941 the ntp config file contain options that change file/dir locations. 942 When such options (e.g., "statsdir" or "crypto") are used, ntpd can 943 still be run as non-root by setting ntpd_user=ntpd in rc.conf, after 944 taking steps to ensure that all required files/dirs are accessible 945 by the ntpd user. 946 94720180717: 948 Big endian arm support has been removed. 949 95020180711: 951 The static environment setup in kernel configs is no longer mutually 952 exclusive with the loader(8) environment by default. In order to 953 restore the previous default behavior of disabling the loader(8) 954 environment if a static environment is present, you must specify 955 loader_env.disabled=1 in the static environment. 956 95720180705: 958 The ABI of syscalls used by management tools like sockstat and 959 netstat has been broken to allow 32-bit binaries to work on 960 64-bit kernels without modification. These programs will need 961 to match the kernel in order to function. External programs may 962 require minor modifications to accommodate a change of type in 963 structures from pointers to 64-bit virtual addresses. 964 96520180702: 966 On i386 and amd64 atomics are now inlined. Out of tree modules using 967 atomics will need to be rebuilt. 968 96920180701: 970 The '%I' format in the kern.corefile sysctl limits the number of 971 core files that a process can generate to the number stored in the 972 debug.ncores sysctl. The '%I' format is replaced by the single digit 973 index. Previously, if all indexes were taken the kernel would overwrite 974 only a core file with the highest index in a filename. 975 Currently the system will create a new core file if there is a free 976 index or if all slots are taken it will overwrite the oldest one. 977 97820180630: 979 Clang, llvm, lld, lldb, compiler-rt and libc++ have been upgraded to 980 6.0.1. Please see the 20141231 entry below for information about 981 prerequisites and upgrading, if you are not already using clang 3.5.0 982 or higher. 983 98420180628: 985 r335753 introduced a new quoting method. However, etc/devd/devmatch.conf 986 needed to be changed to work with it. This change was made with r335763 987 and requires a mergemaster / etcupdate / etc to update the installed 988 file. 989 99020180612: 991 r334930 changed the interface between the NFS modules, so they all 992 need to be rebuilt. r335018 did a __FreeBSD_version bump for this. 993 99420180530: 995 As of r334391 lld is the default amd64 system linker; it is installed 996 as /usr/bin/ld. Kernel build workarounds (see 20180510 entry) are no 997 longer necessary. 998 99920180530: 1000 The kernel / userland interface for devinfo changed, so you'll 1001 need a new kernel and userland as a pair for it to work (rebuilding 1002 lib/libdevinfo is all that's required). devinfo and devmatch will 1003 not work, but everything else will when there's a mismatch. 1004 100520180523: 1006 The on-disk format for hwpmc callchain records has changed to include 1007 threadid corresponding to a given record. This changes the field offsets 1008 and thus requires that libpmcstat be rebuilt before using a kernel 1009 later than r334108. 1010 101120180517: 1012 The vxge(4) driver has been removed. This driver was introduced into 1013 HEAD one week before the Exar left the Ethernet market and is not 1014 known to be used. If you have device vxge in your kernel config file 1015 it must be removed. 1016 101720180510: 1018 The amd64 kernel now requires a ld that supports ifunc to produce a 1019 working kernel, either lld or a newer binutils. lld is built by default 1020 on amd64, and the 'buildkernel' target uses it automatically. However, 1021 it is not the default linker, so building the kernel the traditional 1022 way requires LD=ld.lld on the command line (or LD=/usr/local/bin/ld for 1023 binutils port/package). lld will soon be default, and this requirement 1024 will go away. 1025 1026 NOTE: As of r334391 lld is the default system linker on amd64, and no 1027 workaround is necessary. 1028 102920180508: 1030 The nxge(4) driver has been removed. This driver was for PCI-X 10g 1031 cards made by s2io/Neterion. The company was acquired by Exar and 1032 no longer sells or supports Ethernet products. If you have device 1033 nxge in your kernel config file it must be removed. 1034 103520180504: 1036 The tz database (tzdb) has been updated to 2018e. This version more 1037 correctly models time stamps in time zones with negative DST such as 1038 Europe/Dublin (from 1971 on), Europe/Prague (1946/7), and 1039 Africa/Windhoek (1994/2017). This does not affect the UT offsets, only 1040 time zone abbreviations and the tm_isdst flag. 1041 104220180502: 1043 The ixgb(4) driver has been removed. This driver was for an early and 1044 uncommon legacy PCI 10GbE for a single ASIC, Intel 82597EX. Intel 1045 quickly shifted to the long lived ixgbe family. If you have device 1046 ixgb in your kernel config file it must be removed. 1047 104820180501: 1049 The lmc(4) driver has been removed. This was a WAN interface 1050 card that was already reportedly rare in 2003, and had an ambiguous 1051 license. If you have device lmc in your kernel config file it must 1052 be removed. 1053 105420180413: 1055 Support for Arcnet networks has been removed. If you have device 1056 arcnet or device cm in your kernel config file they must be 1057 removed. 1058 105920180411: 1060 Support for FDDI networks has been removed. If you have device 1061 fddi or device fpa in your kernel config file they must be 1062 removed. 1063 106420180406: 1065 In addition to supporting RFC 3164 formatted messages, the 1066 syslogd(8) service is now capable of parsing RFC 5424 formatted 1067 log messages. The main benefit of using RFC 5424 is that clients 1068 may now send log messages with timestamps containing year numbers, 1069 microseconds and time zone offsets. 1070 1071 Similarly, the syslog(3) C library function has been altered to 1072 send RFC 5424 formatted messages to the local system logging 1073 daemon. On systems using syslogd(8), this change should have no 1074 negative impact, as long as syslogd(8) and the C library are 1075 updated at the same time. On systems using a different system 1076 logging daemon, it may be necessary to make configuration 1077 adjustments, depending on the software used. 1078 1079 When using syslog-ng, add the 'syslog-protocol' flag to local 1080 input sources to enable parsing of RFC 5424 formatted messages: 1081 1082 source src { 1083 unix-dgram("/var/run/log" flags(syslog-protocol)); 1084 } 1085 1086 When using rsyslog, disable the 'SysSock.UseSpecialParser' option 1087 of the 'imuxsock' module to let messages be processed by the 1088 regular RFC 3164/5424 parsing pipeline: 1089 1090 module(load="imuxsock" SysSock.UseSpecialParser="off") 1091 1092 Do note that these changes only affect communication between local 1093 applications and syslogd(8). The format that syslogd(8) uses to 1094 store messages on disk or forward messages to other systems 1095 remains unchanged. syslogd(8) still uses RFC 3164 for these 1096 purposes. Options to customize this behaviour will be added in the 1097 future. Utilities that process log files stored in /var/log are 1098 thus expected to continue to function as before. 1099 1100 __FreeBSD_version has been incremented to 1200061 to denote this 1101 change. 1102 110320180328: 1104 Support for token ring networks has been removed. If you 1105 have "device token" in your kernel config you should remove 1106 it. No device drivers supported token ring. 1107 110820180323: 1109 makefs was modified to be able to tag ISO9660 El Torito boot catalog 1110 entries as EFI instead of overloading the i386 tag as done previously. 1111 The amd64 mkisoimages.sh script used to build amd64 ISO images for 1112 release was updated to use this. This may mean that makefs must be 1113 updated before "make cdrom" can be run in the release directory. This 1114 should be as simple as: 1115 1116 $ cd $SRCDIR/usr.sbin/makefs 1117 $ make depend all install 1118 111920180212: 1120 FreeBSD boot loader enhanced with Lua scripting. It's purely opt-in for 1121 now by building WITH_LOADER_LUA and WITHOUT_FORTH in /etc/src.conf. 1122 Co-existence for the transition period will come shortly. Booting is a 1123 complex environment and test coverage for Lua-enabled loaders has been 1124 thin, so it would be prudent to assume it might not work and make 1125 provisions for backup boot methods. 1126 112720180211: 1128 devmatch functionality has been turned on in devd. It will automatically 1129 load drivers for unattached devices. This may cause unexpected drivers 1130 to be loaded. Please report any problems to current@ and 1131 imp@freebsd.org. 1132 113320180114: 1134 Clang, llvm, lld, lldb, compiler-rt and libc++ have been upgraded to 1135 6.0.0. Please see the 20141231 entry below for information about 1136 prerequisites and upgrading, if you are not already using clang 3.5.0 1137 or higher. 1138 113920180110: 1140 LLVM's lld linker is now used as the FreeBSD/amd64 bootstrap linker. 1141 This means it is used to link the kernel and userland libraries and 1142 executables, but is not yet installed as /usr/bin/ld by default. 1143 1144 To revert to ld.bfd as the bootstrap linker, in /etc/src.conf set 1145 WITHOUT_LLD_BOOTSTRAP=yes 1146 114720180110: 1148 On i386, pmtimer has been removed. Its functionality has been folded 1149 into apm. It was a no-op on ACPI in current for a while now (but was 1150 still needed on i386 in FreeBSD 11 and earlier). Users may need to 1151 remove it from kernel config files. 1152 115320180104: 1154 The use of RSS hash from the network card aka flowid has been 1155 disabled by default for lagg(4) as it's currently incompatible with 1156 the lacp and loadbalance protocols. 1157 1158 This can be re-enabled by setting the following in loader.conf: 1159 net.link.lagg.default_use_flowid="1" 1160 116120180102: 1162 The SW_WATCHDOG option is no longer necessary to enable the 1163 hardclock-based software watchdog if no hardware watchdog is 1164 configured. As before, SW_WATCHDOG will cause the software 1165 watchdog to be enabled even if a hardware watchdog is configured. 1166 116720171215: 1168 r326887 fixes the issue described in the 20171214 UPDATING entry. 1169 r326888 flips the switch back to building GELI support always. 1170 117120171214: 1172 r362593 broke ZFS + GELI support for reasons unknown. However, 1173 it also broke ZFS support generally, so GELI has been turned off 1174 by default as the lesser evil in r326857. If you boot off ZFS and/or 1175 GELI, it might not be a good time to update. 1176 117720171125: 1178 PowerPC users must update loader(8) by rebuilding world before 1179 installing a new kernel, as the protocol connecting them has 1180 changed. Without the update, loader metadata will not be passed 1181 successfully to the kernel and users will have to enter their 1182 root partition at the kernel mountroot prompt to continue booting. 1183 Newer versions of loader can boot old kernels without issue. 1184 118520171110: 1186 The LOADER_FIREWIRE_SUPPORT build variable has been renamed to 1187 WITH/OUT_LOADER_FIREWIRE. LOADER_{NO_,}GELI_SUPPORT has been renamed 1188 to WITH/OUT_LOADER_GELI. 1189 119020171106: 1191 The naive and non-compliant support of posix_fallocate(2) in ZFS 1192 has been removed as of r325320. The system call now returns EINVAL 1193 when used on a ZFS file. Although the new behavior complies with the 1194 standard, some consumers are not prepared to cope with it. 1195 One known victim is lld prior to r325420. 1196 119720171102: 1198 Building in a FreeBSD src checkout will automatically create object 1199 directories now rather than store files in the current directory if 1200 'make obj' was not ran. Calling 'make obj' is no longer necessary. 1201 This feature can be disabled by setting WITHOUT_AUTO_OBJ=yes in 1202 /etc/src-env.conf (not /etc/src.conf), or passing the option in the 1203 environment. 1204 120520171101: 1206 The default MAKEOBJDIR has changed from /usr/obj/<srcdir> for native 1207 builds, and /usr/obj/<arch>/<srcdir> for cross-builds, to a unified 1208 /usr/obj/<srcdir>/<arch>. This behavior can be changed to the old 1209 format by setting WITHOUT_UNIFIED_OBJDIR=yes in /etc/src-env.conf, 1210 the environment, or with -DWITHOUT_UNIFIED_OBJDIR when building. 1211 The UNIFIED_OBJDIR option is a transitional feature that will be 1212 removed for 12.0 release; please migrate to the new format for any 1213 tools by looking up the OBJDIR used by 'make -V .OBJDIR' means rather 1214 than hardcoding paths. 1215 121620171028: 1217 The native-xtools target no longer installs the files by default to the 1218 OBJDIR. Use the native-xtools-install target with a DESTDIR to install 1219 to ${DESTDIR}/${NXTP} where NXTP defaults to /nxb-bin. 1220 122120171021: 1222 As part of the boot loader infrastructure cleanup, LOADER_*_SUPPORT 1223 options are changing from controlling the build if defined / undefined 1224 to controlling the build with explicit 'yes' or 'no' values. They will 1225 shift to WITH/WITHOUT options to match other options in the system. 1226 122720171010: 1228 libstand has turned into a private library for sys/boot use only. 1229 It is no longer supported as a public interface outside of sys/boot. 1230 123120171005: 1232 The arm port has split armv6 into armv6 and armv7. armv7 is now 1233 a valid TARGET_ARCH/MACHINE_ARCH setting. If you have an armv7 system 1234 and are running a kernel from before r324363, you will need to add 1235 MACHINE_ARCH=armv7 to 'make buildworld' to do a native build. 1236 123720171003: 1238 When building multiple kernels using KERNCONF, non-existent KERNCONF 1239 files will produce an error and buildkernel will fail. Previously 1240 missing KERNCONF files silently failed giving no indication as to 1241 why, only to subsequently discover during installkernel that the 1242 desired kernel was never built in the first place. 1243 124420170912: 1245 The default serial number format for CTL LUNs has changed. This will 1246 affect users who use /dev/diskid/* device nodes, or whose FibreChannel 1247 or iSCSI clients care about their LUNs' serial numbers. Users who 1248 require serial number stability should hardcode serial numbers in 1249 /etc/ctl.conf . 1250 125120170912: 1252 For 32-bit arm compiled for hard-float support, soft-floating point 1253 binaries now always get their shared libraries from 1254 LD_SOFT_LIBRARY_PATH (in the past, this was only used if 1255 /usr/libsoft also existed). Only users with a hard-float ld.so, but 1256 soft-float everything else should be affected. 1257 125820170826: 1259 The geli password typed at boot is now hidden. To restore the previous 1260 behavior, see geli(8) for configuration options. 1261 126220170825: 1263 Move PMTUD blackhole counters to TCPSTATS and remove them from bare 1264 sysctl values. Minor nit, but requires a rebuild of both world/kernel 1265 to complete. 1266 126720170814: 1268 "make check" behavior (made in ^/head@r295380) has been changed to 1269 execute from a limited sandbox, as opposed to executing from 1270 ${TESTSDIR}. 1271 1272 Behavioral changes: 1273 - The "beforecheck" and "aftercheck" targets are now specified. 1274 - ${CHECKDIR} (added in commit noted above) has been removed. 1275 - Legacy behavior can be enabled by setting 1276 WITHOUT_MAKE_CHECK_USE_SANDBOX in src.conf(5) or the environment. 1277 1278 If the limited sandbox mode is enabled, "make check" will execute 1279 "make distribution", then install, execute the tests, and clean up the 1280 sandbox if successful. 1281 1282 The "make distribution" and "make install" targets are typically run as 1283 root to set appropriate permissions and ownership at installation time. 1284 The end-user should set "WITH_INSTALL_AS_USER" in src.conf(5) or the 1285 environment if executing "make check" with limited sandbox mode using 1286 an unprivileged user. 1287 128820170808: 1289 Since the switch to GPT disk labels, fsck for UFS/FFS has been 1290 unable to automatically find alternate superblocks. As of r322297, 1291 the information needed to find alternate superblocks has been 1292 moved to the end of the area reserved for the boot block. 1293 Filesystems created with a newfs of this vintage or later 1294 will create the recovery information. If you have a filesystem 1295 created prior to this change and wish to have a recovery block 1296 created for your filesystem, you can do so by running fsck in 1297 foreground mode (i.e., do not use the -p or -y options). As it 1298 starts, fsck will ask ``SAVE DATA TO FIND ALTERNATE SUPERBLOCKS'' 1299 to which you should answer yes. 1300 130120170728: 1302 As of r321665, an NFSv4 server configuration that services 1303 Kerberos mounts or clients that do not support the uid/gid in 1304 owner/owner_group string capability, must explicitly enable 1305 the nfsuserd daemon by adding nfsuserd_enable="YES" to the 1306 machine's /etc/rc.conf file. 1307 130820170722: 1309 Clang, llvm, lldb, compiler-rt and libc++ have been upgraded to 5.0.0. 1310 Please see the 20141231 entry below for information about prerequisites 1311 and upgrading, if you are not already using clang 3.5.0 or higher. 1312 131320170701: 1314 WITHOUT_RCMDS is now the default. Set WITH_RCMDS if you need the 1315 r-commands (rlogin, rsh, etc.) to be built with the base system. 1316 131720170625: 1318 The FreeBSD/powerpc platform now uses a 64-bit type for time_t. This is 1319 a very major ABI incompatible change, so users of FreeBSD/powerpc must 1320 be careful when performing source upgrades. It is best to run 1321 'make installworld' from an alternate root system, either a live 1322 CD/memory stick, or a temporary root partition. Additionally, all ports 1323 must be recompiled. powerpc64 is largely unaffected, except in the case 1324 of 32-bit compatibility. All 32-bit binaries will be affected. 1325 132620170623: 1327 Forward compatibility for the "ino64" project have been committed. This 1328 will allow most new binaries to run on older kernels in a limited 1329 fashion. This prevents many of the common foot-shooting actions in the 1330 upgrade as well as the limited ability to roll back the kernel across 1331 the ino64 upgrade. Complicated use cases may not work properly, though 1332 enough simpler ones work to allow recovery in most situations. 1333 133420170620: 1335 Switch back to the BSDL dtc (Device Tree Compiler). Set WITH_GPL_DTC 1336 if you require the GPL compiler. 1337 133820170618: 1339 The internal ABI used for communication between the NFS kernel modules 1340 was changed by r320085, so __FreeBSD_version was bumped to 1341 ensure all the NFS related modules are updated together. 1342 134320170617: 1344 The ABI of struct event was changed by extending the data 1345 member to 64bit and adding ext fields. For upgrade, same 1346 precautions as for the entry 20170523 "ino64" must be 1347 followed. 1348 134920170531: 1350 The GNU roff toolchain has been removed from base. To render manpages 1351 which are not supported by mandoc(1), man(1) can fallback on GNU roff 1352 from ports (and recommends to install it). 1353 To render roff(7) documents, consider using GNU roff from ports or the 1354 heirloom doctools roff toolchain from ports via pkg install groff or 1355 via pkg install heirloom-doctools. 1356 135720170524: 1358 The ath(4) and ath_hal(4) modules now build piecemeal to allow for 1359 smaller runtime footprint builds. This is useful for embedded systems 1360 which only require one chipset support. 1361 1362 If you load it as a module, make sure this is in /boot/loader.conf: 1363 1364 if_ath_load="YES" 1365 1366 This will load the HAL, all chip/RF backends and if_ath_pci. 1367 If you have if_ath_pci in /boot/loader.conf, ensure it is after 1368 if_ath or it will not load any HAL chipset support. 1369 1370 If you want to selectively load things (eg on cheaper ARM/MIPS 1371 platforms where RAM is at a premium) you should: 1372 1373 * load ath_hal 1374 * load the chip modules in question 1375 * load ath_rate, ath_dfs 1376 * load ath_main 1377 * load if_ath_pci and/or if_ath_ahb depending upon your particular 1378 bus bind type - this is where probe/attach is done. 1379 1380 For further comments/feedback, poke adrian@ . 1381 138220170523: 1383 The "ino64" 64-bit inode project has been committed, which extends 1384 a number of types to 64 bits. Upgrading in place requires care and 1385 adherence to the documented upgrade procedure. 1386 1387 If using a custom kernel configuration ensure that the 1388 COMPAT_FREEBSD11 option is included (as during the upgrade the 1389 system will be running the ino64 kernel with the existing world). 1390 1391 For the safest in-place upgrade begin by removing previous build 1392 artifacts via "rm -rf /usr/obj/*". Then, carefully follow the full 1393 procedure documented below under the heading "To rebuild everything and 1394 install it on the current system." Specifically, a reboot is required 1395 after installing the new kernel before installing world. While an 1396 installworld normally works by accident from multiuser after rebooting 1397 the proper kernel, there are many cases where this will fail across this 1398 upgrade and installworld from single user is required. 1399 140020170424: 1401 The NATM framework including the en(4), fatm(4), hatm(4), and 1402 patm(4) devices has been removed. Consumers should plan a 1403 migration before the end-of-life date for FreeBSD 11. 1404 140520170420: 1406 GNU diff has been replaced by a BSD licensed diff. Some features of GNU 1407 diff has not been implemented, if those are needed a newer version of 1408 GNU diff is available via the diffutils package under the gdiff name. 1409 141020170413: 1411 As of r316810 for ipfilter, keep frags is no longer assumed when 1412 keep state is specified in a rule. r316810 aligns ipfilter with 1413 documentation in man pages separating keep frags from keep state. 1414 This allows keep state to be specified without forcing keep frags 1415 and allows keep frags to be specified independently of keep state. 1416 To maintain previous behaviour, also specify keep frags with 1417 keep state (as documented in ipf.conf.5). 1418 141920170407: 1420 arm64 builds now use the base system LLD 4.0.0 linker by default, 1421 instead of requiring that the aarch64-binutils port or package be 1422 installed. To continue using aarch64-binutils, set 1423 CROSS_BINUTILS_PREFIX=/usr/local/aarch64-freebsd/bin . 1424 142520170405: 1426 The UDP optimization in entry 20160818 that added the sysctl 1427 net.inet.udp.require_l2_bcast has been reverted. L2 broadcast 1428 packets will no longer be treated as L3 broadcast packets. 1429 143020170331: 1431 Binds and sends to the loopback addresses, IPv6 and IPv4, will now 1432 use any explicitly assigned loopback address available in the jail 1433 instead of using the first assigned address of the jail. 1434 143520170329: 1436 The ctl.ko module no longer implements the iSCSI target frontend: 1437 cfiscsi.ko does instead. 1438 1439 If building cfiscsi.ko as a kernel module, the module can be loaded 1440 via one of the following methods: 1441 - `cfiscsi_load="YES"` in loader.conf(5). 1442 - Add `cfiscsi` to `$kld_list` in rc.conf(5). 1443 - ctladm(8)/ctld(8), when compiled with iSCSI support 1444 (`WITH_ISCSI=yes` in src.conf(5)) 1445 1446 Please see cfiscsi(4) for more details. 1447 144820170316: 1449 The mmcsd.ko module now additionally depends on geom_flashmap.ko. 1450 Also, mmc.ko and mmcsd.ko need to be a matching pair built from the 1451 same source (previously, the dependency of mmcsd.ko on mmc.ko was 1452 missing, but mmcsd.ko now will refuse to load if it is incompatible 1453 with mmc.ko). 1454 145520170315: 1456 The syntax of ipfw(8) named states was changed to avoid ambiguity. 1457 If you have used named states in the firewall rules, you need to modify 1458 them after installworld and before rebooting. Now named states must 1459 be prefixed with colon. 1460 146120170311: 1462 The old drm (sys/dev/drm/) drivers for i915 and radeon have been 1463 removed as the userland we provide cannot use them. The KMS version 1464 (sys/dev/drm2) supports the same hardware. 1465 146620170302: 1467 Clang, llvm, lldb, compiler-rt and libc++ have been upgraded to 4.0.0. 1468 Please see the 20141231 entry below for information about prerequisites 1469 and upgrading, if you are not already using clang 3.5.0 or higher. 1470 147120170221: 1472 The code that provides support for ZFS .zfs/ directory functionality 1473 has been reimplemented. It's not possible now to create a snapshot 1474 by mkdir under .zfs/snapshot/. That should be the only user visible 1475 change. 1476 147720170216: 1478 EISA bus support has been removed. The WITH_EISA option is no longer 1479 valid. 1480 148120170215: 1482 MCA bus support has been removed. 1483 148420170127: 1485 The WITH_LLD_AS_LD / WITHOUT_LLD_AS_LD build knobs have been renamed 1486 WITH_LLD_IS_LD / WITHOUT_LLD_IS_LD, for consistency with CLANG_IS_CC. 1487 148820170112: 1489 The EM_MULTIQUEUE kernel configuration option is deprecated now that 1490 the em(4) driver conforms to iflib specifications. 1491 149220170109: 1493 The igb(4), em(4) and lem(4) ethernet drivers are now implemented via 1494 IFLIB. If you have a custom kernel configuration that excludes em(4) 1495 but you use igb(4), you need to re-add em(4) to your custom 1496 configuration. 1497 149820161217: 1499 Clang, llvm, lldb, compiler-rt and libc++ have been upgraded to 3.9.1. 1500 Please see the 20141231 entry below for information about prerequisites 1501 and upgrading, if you are not already using clang 3.5.0 or higher. 1502 150320161124: 1504 Clang, llvm, lldb, compiler-rt and libc++ have been upgraded to 3.9.0. 1505 Please see the 20141231 entry below for information about prerequisites 1506 and upgrading, if you are not already using clang 3.5.0 or higher. 1507 150820161119: 1509 The layout of the pmap structure has changed for powerpc to put the pmap 1510 statistics at the front for all CPU variations. libkvm(3) and all tools 1511 that link against it need to be recompiled. 1512 151320161030: 1514 isl(4) and cyapa(4) drivers now require a new driver, 1515 chromebook_platform(4), to work properly on Chromebook-class hardware. 1516 On other types of hardware the drivers may need to be configured using 1517 device hints. Please see the corresponding manual pages for details. 1518 151920161017: 1520 The urtwn(4) driver was merged into rtwn(4) and now consists of 1521 rtwn(4) main module + rtwn_usb(4) and rtwn_pci(4) bus-specific 1522 parts. 1523 Also, firmware for RTL8188CE was renamed due to possible name 1524 conflict (rtwnrtl8192cU(B) -> rtwnrtl8192cE(B)) 1525 152620161015: 1527 GNU rcs has been removed from base. It is available as packages: 1528 - rcs: Latest GPLv3 GNU rcs version. 1529 - rcs57: Copy of the latest version of GNU rcs (GPLv2) before it was 1530 removed from base. 1531 153220161008: 1533 Use of the cc_cdg, cc_chd, cc_hd, or cc_vegas congestion control 1534 modules now requires that the kernel configuration contain the 1535 TCP_HHOOK option. (This option is included in the GENERIC kernel.) 1536 153720161003: 1538 The WITHOUT_ELFCOPY_AS_OBJCOPY src.conf(5) knob has been retired. 1539 ELF Tool Chain's elfcopy is always installed as /usr/bin/objcopy. 1540 154120160924: 1542 Relocatable object files with the extension of .So have been renamed 1543 to use an extension of .pico instead. The purpose of this change is 1544 to avoid a name clash with shared libraries on case-insensitive file 1545 systems. On those file systems, foo.So is the same file as foo.so. 1546 154720160918: 1548 GNU rcs has been turned off by default. It can (temporarily) be built 1549 again by adding WITH_RCS knob in src.conf. 1550 Otherwise, GNU rcs is available from packages: 1551 - rcs: Latest GPLv3 GNU rcs version. 1552 - rcs57: Copy of the latest version of GNU rcs (GPLv2) from base. 1553 155420160918: 1555 The backup_uses_rcs functionality has been removed from rc.subr. 1556 155720160908: 1558 The queue(3) debugging macro, QUEUE_MACRO_DEBUG, has been split into 1559 two separate components, QUEUE_MACRO_DEBUG_TRACE and 1560 QUEUE_MACRO_DEBUG_TRASH. Define both for the original 1561 QUEUE_MACRO_DEBUG behavior. 1562 156320160824: 1564 r304787 changed some ioctl interfaces between the iSCSI userspace 1565 programs and the kernel. ctladm, ctld, iscsictl, and iscsid must be 1566 rebuilt to work with new kernels. __FreeBSD_version has been bumped 1567 to 1200005. 1568 156920160818: 1570 The UDP receive code has been updated to only treat incoming UDP 1571 packets that were addressed to an L2 broadcast address as L3 1572 broadcast packets. It is not expected that this will affect any 1573 standards-conforming UDP application. The new behaviour can be 1574 disabled by setting the sysctl net.inet.udp.require_l2_bcast to 1575 0. 1576 157720160818: 1578 Remove the openbsd_poll system call. 1579 __FreeBSD_version has been bumped because of this. 1580 158120160708: 1582 The stable/11 branch has been created from head@r302406. 1583 158420160622: 1585 The libc stub for the pipe(2) system call has been replaced with 1586 a wrapper that calls the pipe2(2) system call and the pipe(2) 1587 system call is now only implemented by the kernels that include 1588 "options COMPAT_FREEBSD10" in their config file (this is the 1589 default). Users should ensure that this option is enabled in 1590 their kernel or upgrade userspace to r302092 before upgrading their 1591 kernel. 1592 159320160527: 1594 CAM now strips the leading spaces from each SCSI disk's serial number. 1595 This will affect users who create UFS filesystems on SCSI disks using 1596 those disk's diskid device nodes. For example, if /etc/fstab 1597 previously contained a line like 1598 "/dev/diskid/DISK-%20%20%20%20%20%20%20ABCDEFG0123456", you should 1599 change it to "/dev/diskid/DISK-ABCDEFG0123456". Users of geom 1600 transforms like gmirror may also be affected. ZFS users should 1601 generally be fine. 1602 160320160523: 1604 The bitstring(3) API has been updated with new functionality and 1605 improved performance. But it is binary-incompatible with the old API. 1606 Objects built with the new headers may not be linked against objects 1607 built with the old headers. 1608 160920160520: 1610 The brk and sbrk functions have been removed from libc on arm64. 1611 Binutils from ports has been updated to not link to these 1612 functions and should be updated to the latest version before 1613 installing a new libc. 1614 161520160517: 1616 The armv6 port now defaults to hard float ABI. Limited support 1617 for running both hardfloat and soft float on the same system 1618 is available using the libraries installed with -DWITH_LIBSOFT. 1619 This has only been tested as an upgrade path for installworld 1620 and packages may fail or need manual intervention to run. New 1621 packages will be needed. 1622 1623 To update an existing self-hosted armv6hf system, you must add 1624 TARGET_ARCH=armv6 on the make command line for both the build 1625 and the install steps. 1626 162720160510: 1628 Kernel modules compiled outside of a kernel build now default to 1629 installing to /boot/modules instead of /boot/kernel. Many kernel 1630 modules built this way (such as those in ports) already overrode 1631 KMODDIR explicitly to install into /boot/modules. However, 1632 manually building and installing a module from /sys/modules will 1633 now install to /boot/modules instead of /boot/kernel. 1634 163520160414: 1636 The CAM I/O scheduler has been committed to the kernel. There should be 1637 no user visible impact. This does enable NCQ Trim on ada SSDs. While the 1638 list of known rogues that claim support for this but actually corrupt 1639 data is believed to be complete, be on the lookout for data 1640 corruption. The known rogue list is believed to be complete: 1641 1642 o Crucial MX100, M550 drives with MU01 firmware. 1643 o Micron M510 and M550 drives with MU01 firmware. 1644 o Micron M500 prior to MU07 firmware 1645 o Samsung 830, 840, and 850 all firmwares 1646 o FCCT M500 all firmwares 1647 1648 Crucial has firmware http://www.crucial.com/usa/en/support-ssd-firmware 1649 with working NCQ TRIM. For Micron branded drives, see your sales rep for 1650 updated firmware. Black listed drives will work correctly because these 1651 drives work correctly so long as no NCQ TRIMs are sent to them. Given 1652 this list is the same as found in Linux, it's believed there are no 1653 other rogues in the market place. All other models from the above 1654 vendors work. 1655 1656 To be safe, if you are at all concerned, you can quirk each of your 1657 drives to prevent NCQ from being sent by setting: 1658 kern.cam.ada.X.quirks="0x2" 1659 in loader.conf. If the drive requires the 4k sector quirk, set the 1660 quirks entry to 0x3. 1661 166220160330: 1663 The FAST_DEPEND build option has been removed and its functionality is 1664 now the one true way. The old mkdep(1) style of 'make depend' has 1665 been removed. See 20160311 for further details. 1666 166720160317: 1668 Resource range types have grown from unsigned long to uintmax_t. All 1669 drivers, and anything using libdevinfo, need to be recompiled. 1670 167120160311: 1672 WITH_FAST_DEPEND is now enabled by default for in-tree and out-of-tree 1673 builds. It no longer runs mkdep(1) during 'make depend', and the 1674 'make depend' stage can safely be skipped now as it is auto ran 1675 when building 'make all' and will generate all SRCS and DPSRCS before 1676 building anything else. Dependencies are gathered at compile time with 1677 -MF flags kept in separate .depend files per object file. Users should 1678 run 'make cleandepend' once if using -DNO_CLEAN to clean out older 1679 stale .depend files. 1680 168120160306: 1682 On amd64, clang 3.8.0 can now insert sections of type AMD64_UNWIND into 1683 kernel modules. Therefore, if you load any kernel modules at boot time, 1684 please install the boot loaders after you install the kernel, but before 1685 rebooting, e.g.: 1686 1687 make buildworld 1688 make buildkernel KERNCONF=YOUR_KERNEL_HERE 1689 make installkernel KERNCONF=YOUR_KERNEL_HERE 1690 make -C sys/boot install 1691 <reboot in single user> 1692 1693 Then follow the usual steps, described in the General Notes section, 1694 below. 1695 169620160305: 1697 Clang, llvm, lldb and compiler-rt have been upgraded to 3.8.0. Please 1698 see the 20141231 entry below for information about prerequisites and 1699 upgrading, if you are not already using clang 3.5.0 or higher. 1700 170120160301: 1702 The AIO subsystem is now a standard part of the kernel. The 1703 VFS_AIO kernel option and aio.ko kernel module have been removed. 1704 Due to stability concerns, asynchronous I/O requests are only 1705 permitted on sockets and raw disks by default. To enable 1706 asynchronous I/O requests on all file types, set the 1707 vfs.aio.enable_unsafe sysctl to a non-zero value. 1708 170920160226: 1710 The ELF object manipulation tool objcopy is now provided by the 1711 ELF Tool Chain project rather than by GNU binutils. It should be a 1712 drop-in replacement, with the addition of arm64 support. The 1713 (temporary) src.conf knob WITHOUT_ELFCOPY_AS_OBJCOPY knob may be set 1714 to obtain the GNU version if necessary. 1715 171620160129: 1717 Building ZFS pools on top of zvols is prohibited by default. That 1718 feature has never worked safely; it's always been prone to deadlocks. 1719 Using a zvol as the backing store for a VM guest's virtual disk will 1720 still work, even if the guest is using ZFS. Legacy behavior can be 1721 restored by setting vfs.zfs.vol.recursive=1. 1722 172320160119: 1724 The NONE and HPN patches has been removed from OpenSSH. They are 1725 still available in the security/openssh-portable port. 1726 172720160113: 1728 With the addition of ypldap(8), a new _ypldap user is now required 1729 during installworld. "mergemaster -p" can be used to add the user 1730 prior to installworld, as documented in the handbook. 1731 173220151216: 1733 The tftp loader (pxeboot) now uses the option root-path directive. As a 1734 consequence it no longer looks for a pxeboot.4th file on the tftp 1735 server. Instead it uses the regular /boot infrastructure as with the 1736 other loaders. 1737 173820151211: 1739 The code to start recording plug and play data into the modules has 1740 been committed. While the old tools will properly build a new kernel, 1741 a number of warnings about "unknown metadata record 4" will be produced 1742 for an older kldxref. To avoid such warnings, make sure to rebuild 1743 the kernel toolchain (or world). Make sure that you have r292078 or 1744 later when trying to build 292077 or later before rebuilding. 1745 174620151207: 1747 Debug data files are now built by default with 'make buildworld' and 1748 installed with 'make installworld'. This facilitates debugging but 1749 requires more disk space both during the build and for the installed 1750 world. Debug files may be disabled by setting WITHOUT_DEBUG_FILES=yes 1751 in src.conf(5). 1752 175320151130: 1754 r291527 changed the internal interface between the nfsd.ko and 1755 nfscommon.ko modules. As such, they must both be upgraded to-gether. 1756 __FreeBSD_version has been bumped because of this. 1757 175820151108: 1759 Add support for unicode collation strings leads to a change of 1760 order of files listed by ls(1) for example. To get back to the old 1761 behaviour, set LC_COLLATE environment variable to "C". 1762 1763 Databases administrators will need to reindex their databases given 1764 collation results will be different. 1765 1766 Due to a bug in install(1) it is recommended to remove the ancient 1767 locales before running make installworld. 1768 1769 rm -rf /usr/share/locale/* 1770 177120151030: 1772 The OpenSSL has been upgraded to 1.0.2d. Any binaries requiring 1773 libcrypto.so.7 or libssl.so.7 must be recompiled. 1774 177520151020: 1776 Qlogic 24xx/25xx firmware images were updated from 5.5.0 to 7.3.0. 1777 Kernel modules isp_2400_multi and isp_2500_multi were removed and 1778 should be replaced with isp_2400 and isp_2500 modules respectively. 1779 178020151017: 1781 The build previously allowed using 'make -n' to not recurse into 1782 sub-directories while showing what commands would be executed, and 1783 'make -n -n' to recursively show commands. Now 'make -n' will recurse 1784 and 'make -N' will not. 1785 178620151012: 1787 If you specify SENDMAIL_MC or SENDMAIL_CF in make.conf, mergemaster 1788 and etcupdate will now use this file. A custom sendmail.cf is now 1789 updated via this mechanism rather than via installworld. If you had 1790 excluded sendmail.cf in mergemaster.rc or etcupdate.conf, you may 1791 want to remove the exclusion or change it to "always install". 1792 /etc/mail/sendmail.cf is now managed the same way regardless of 1793 whether SENDMAIL_MC/SENDMAIL_CF is used. If you are not using 1794 SENDMAIL_MC/SENDMAIL_CF there should be no change in behavior. 1795 179620151011: 1797 Compatibility shims for legacy ATA device names have been removed. 1798 It includes ATA_STATIC_ID kernel option, kern.cam.ada.legacy_aliases 1799 and kern.geom.raid.legacy_aliases loader tunables, kern.devalias.* 1800 environment variables, /dev/ad* and /dev/ar* symbolic links. 1801 180220151006: 1803 Clang, llvm, lldb, compiler-rt and libc++ have been upgraded to 3.7.0. 1804 Please see the 20141231 entry below for information about prerequisites 1805 and upgrading, if you are not already using clang 3.5.0 or higher. 1806 180720150924: 1808 Kernel debug files have been moved to /usr/lib/debug/boot/kernel/, 1809 and renamed from .symbols to .debug. This reduces the size requirements 1810 on the boot partition or file system and provides consistency with 1811 userland debug files. 1812 1813 When using the supported kernel installation method the 1814 /usr/lib/debug/boot/kernel directory will be renamed (to kernel.old) 1815 as is done with /boot/kernel. 1816 1817 Developers wishing to maintain the historical behavior of installing 1818 debug files in /boot/kernel/ can set KERN_DEBUGDIR="" in src.conf(5). 1819 182020150827: 1821 The wireless drivers had undergone changes that remove the 'parent 1822 interface' from the ifconfig -l output. The rc.d network scripts 1823 used to check presence of a parent interface in the list, so old 1824 scripts would fail to start wireless networking. Thus, etcupdate(3) 1825 or mergemaster(8) run is required after kernel update, to update your 1826 rc.d scripts in /etc. 1827 182820150827: 1829 pf no longer supports 'scrub fragment crop' or 'scrub fragment drop-ovl' 1830 These configurations are now automatically interpreted as 1831 'scrub fragment reassemble'. 1832 183320150817: 1834 Kernel-loadable modules for the random(4) device are back. To use 1835 them, the kernel must have 1836 1837 device random 1838 options RANDOM_LOADABLE 1839 1840 kldload(8) can then be used to load random_fortuna.ko 1841 or random_yarrow.ko. Please note that due to the indirect 1842 function calls that the loadable modules need to provide, 1843 the build-in variants will be slightly more efficient. 1844 1845 The random(4) kernel option RANDOM_DUMMY has been retired due to 1846 unpopularity. It was not all that useful anyway. 1847 184820150813: 1849 The WITHOUT_ELFTOOLCHAIN_TOOLS src.conf(5) knob has been retired. 1850 Control over building the ELF Tool Chain tools is now provided by 1851 the WITHOUT_TOOLCHAIN knob. 1852 185320150810: 1854 The polarity of Pulse Per Second (PPS) capture events with the 1855 uart(4) driver has been corrected. Prior to this change the PPS 1856 "assert" event corresponded to the trailing edge of a positive PPS 1857 pulse and the "clear" event was the leading edge of the next pulse. 1858 1859 As the width of a PPS pulse in a typical GPS receiver is on the 1860 order of 1 millisecond, most users will not notice any significant 1861 difference with this change. 1862 1863 Anyone who has compensated for the historical polarity reversal by 1864 configuring a negative offset equal to the pulse width will need to 1865 remove that workaround. 1866 186720150809: 1868 The default group assigned to /dev/dri entries has been changed 1869 from 'wheel' to 'video' with the id of '44'. If you want to have 1870 access to the dri devices please add yourself to the video group 1871 with: 1872 1873 # pw groupmod video -m $USER 1874 187520150806: 1876 The menu.rc and loader.rc files will now be replaced during 1877 upgrades. Please migrate local changes to menu.rc.local and 1878 loader.rc.local instead. 1879 188020150805: 1881 GNU Binutils versions of addr2line, c++filt, nm, readelf, size, 1882 strings and strip have been removed. The src.conf(5) knob 1883 WITHOUT_ELFTOOLCHAIN_TOOLS no longer provides the binutils tools. 1884 188520150728: 1886 As ZFS requires more kernel stack pages than is the default on some 1887 architectures e.g. i386, it now warns if KSTACK_PAGES is less than 1888 ZFS_MIN_KSTACK_PAGES (which is 4 at the time of writing). 1889 1890 Please consider using 'options KSTACK_PAGES=X' where X is greater 1891 than or equal to ZFS_MIN_KSTACK_PAGES i.e. 4 in such configurations. 1892 189320150706: 1894 sendmail has been updated to 8.15.2. Starting with FreeBSD 11.0 1895 and sendmail 8.15, sendmail uses uncompressed IPv6 addresses by 1896 default, i.e., they will not contain "::". For example, instead 1897 of ::1, it will be 0:0:0:0:0:0:0:1. This permits a zero subnet 1898 to have a more specific match, such as different map entries for 1899 IPv6:0:0 vs IPv6:0. This change requires that configuration 1900 data (including maps, files, classes, custom ruleset, etc.) must 1901 use the same format, so make certain such configuration data is 1902 upgrading. As a very simple check search for patterns like 1903 'IPv6:[0-9a-fA-F:]*::' and 'IPv6::'. To return to the old 1904 behavior, set the m4 option confUSE_COMPRESSED_IPV6_ADDRESSES or 1905 the cf option UseCompressedIPv6Addresses. 1906 190720150630: 1908 The default kernel entropy-processing algorithm is now 1909 Fortuna, replacing Yarrow. 1910 1911 Assuming you have 'device random' in your kernel config 1912 file, the configurations allow a kernel option to override 1913 this default. You may choose *ONE* of: 1914 1915 options RANDOM_YARROW # Legacy /dev/random algorithm. 1916 options RANDOM_DUMMY # Blocking-only driver. 1917 1918 If you have neither, you get Fortuna. For most people, 1919 read no further, Fortuna will give a /dev/random that works 1920 like it always used to, and the difference will be irrelevant. 1921 1922 If you remove 'device random', you get *NO* kernel-processed 1923 entropy at all. This may be acceptable to folks building 1924 embedded systems, but has complications. Carry on reading, 1925 and it is assumed you know what you need. 1926 1927 *PLEASE* read random(4) and random(9) if you are in the 1928 habit of tweaking kernel configs, and/or if you are a member 1929 of the embedded community, wanting specific and not-usual 1930 behaviour from your security subsystems. 1931 1932 NOTE!! If you use RANDOM_DUMMY and/or have no 'device 1933 random', you will NOT have a functioning /dev/random, and 1934 many cryptographic features will not work, including SSH. 1935 You may also find strange behaviour from the random(3) set 1936 of library functions, in particular sranddev(3), srandomdev(3) 1937 and arc4random(3). The reason for this is that the KERN_ARND 1938 sysctl only returns entropy if it thinks it has some to 1939 share, and with RANDOM_DUMMY or no 'device random' this 1940 will never happen. 1941 194220150623: 1943 An additional fix for the issue described in the 20150614 sendmail 1944 entry below has been committed in revision 284717. 1945 194620150616: 1947 FreeBSD's old make (fmake) has been removed from the system. It is 1948 available as the devel/fmake port or via pkg install fmake. 1949 195020150615: 1951 The fix for the issue described in the 20150614 sendmail entry 1952 below has been committed in revision 284436. The work 1953 around described in that entry is no longer needed unless the 1954 default setting is overridden by a confDH_PARAMETERS configuration 1955 setting of '5' or pointing to a 512 bit DH parameter file. 1956 195720150614: 1958 ALLOW_DEPRECATED_ATF_TOOLS/ATFFILE support has been removed from 1959 atf.test.mk (included from bsd.test.mk). Please upgrade devel/atf 1960 and devel/kyua to version 0.20+ and adjust any calling code to work 1961 with Kyuafile and kyua. 1962 196320150614: 1964 The import of openssl to address the FreeBSD-SA-15:10.openssl 1965 security advisory includes a change which rejects handshakes 1966 with DH parameters below 768 bits. sendmail releases prior 1967 to 8.15.2 (not yet released), defaulted to a 512 bit 1968 DH parameter setting for client connections. To work around 1969 this interoperability, sendmail can be configured to use a 1970 2048 bit DH parameter by: 1971 1972 1. Edit /etc/mail/`hostname`.mc 1973 2. If a setting for confDH_PARAMETERS does not exist or 1974 exists and is set to a string beginning with '5', 1975 replace it with '2'. 1976 3. If a setting for confDH_PARAMETERS exists and is set to 1977 a file path, create a new file with: 1978 openssl dhparam -out /path/to/file 2048 1979 4. Rebuild the .cf file: 1980 cd /etc/mail/; make; make install 1981 5. Restart sendmail: 1982 cd /etc/mail/; make restart 1983 1984 A sendmail patch is coming, at which time this file will be 1985 updated. 1986 198720150604: 1988 Generation of legacy formatted entries have been disabled by default 1989 in pwd_mkdb(8), as all base system consumers of the legacy formatted 1990 entries were converted to use the new format by default when the new, 1991 machine independent format have been added and supported since FreeBSD 1992 5.x. 1993 1994 Please see the pwd_mkdb(8) manual page for further details. 1995 199620150525: 1997 Clang and llvm have been upgraded to 3.6.1 release. Please see the 1998 20141231 entry below for information about prerequisites and upgrading, 1999 if you are not already using 3.5.0 or higher. 2000 200120150521: 2002 TI platform code switched to using vendor DTS files and this update 2003 may break existing systems running on Beaglebone, Beaglebone Black, 2004 and Pandaboard: 2005 2006 - dtb files should be regenerated/reinstalled. Filenames are the 2007 same but content is different now 2008 - GPIO addressing was changed, now each GPIO bank (32 pins per bank) 2009 has its own /dev/gpiocX device, e.g. pin 121 on /dev/gpioc0 in old 2010 addressing scheme is now pin 25 on /dev/gpioc3. 2011 - Pandaboard: /etc/ttys should be updated, serial console device is 2012 now /dev/ttyu2, not /dev/ttyu0 2013 201420150501: 2015 soelim(1) from gnu/usr.bin/groff has been replaced by usr.bin/soelim. 2016 If you need the GNU extension from groff soelim(1), install groff 2017 from package: pkg install groff, or via ports: textproc/groff. 2018 201920150423: 2020 chmod, chflags, chown and chgrp now affect symlinks in -R mode as 2021 defined in symlink(7); previously symlinks were silently ignored. 2022 202320150415: 2024 The const qualifier has been removed from iconv(3) to comply with 2025 POSIX. The ports tree is aware of this from r384038 onwards. 2026 202720150416: 2028 Libraries specified by LIBADD in Makefiles must have a corresponding 2029 DPADD_<lib> variable to ensure correct dependencies. This is now 2030 enforced in src.libnames.mk. 2031 203220150324: 2033 From legacy ata(4) driver was removed support for SATA controllers 2034 supported by more functional drivers ahci(4), siis(4) and mvs(4). 2035 Kernel modules ataahci and ataadaptec were removed completely, 2036 replaced by ahci and mvs modules respectively. 2037 203820150315: 2039 Clang, llvm and lldb have been upgraded to 3.6.0 release. Please see 2040 the 20141231 entry below for information about prerequisites and 2041 upgrading, if you are not already using 3.5.0 or higher. 2042 204320150307: 2044 The 32-bit PowerPC kernel has been changed to a position-independent 2045 executable. This can only be booted with a version of loader(8) 2046 newer than January 31, 2015, so make sure to update both world and 2047 kernel before rebooting. 2048 204920150217: 2050 If you are running a -CURRENT kernel since r273872 (Oct 30th, 2014), 2051 but before r278950, the RNG was not seeded properly. Immediately 2052 upgrade the kernel to r278950 or later and regenerate any keys (e.g. 2053 ssh keys or openssl keys) that were generated w/ a kernel from that 2054 range. This does not affect programs that directly used /dev/random 2055 or /dev/urandom. All userland uses of arc4random(3) are affected. 2056 205720150210: 2058 The autofs(4) ABI was changed in order to restore binary compatibility 2059 with 10.1-RELEASE. The automountd(8) daemon needs to be rebuilt to work 2060 with the new kernel. 2061 206220150131: 2063 The powerpc64 kernel has been changed to a position-independent 2064 executable. This can only be booted with a new version of loader(8), 2065 so make sure to update both world and kernel before rebooting. 2066 206720150118: 2068 Clang and llvm have been upgraded to 3.5.1 release. This is a bugfix 2069 only release, no new features have been added. Please see the 20141231 2070 entry below for information about prerequisites and upgrading, if you 2071 are not already using 3.5.0. 2072 207320150107: 2074 ELF tools addr2line, elfcopy (strip), nm, size, and strings are now 2075 taken from the ELF Tool Chain project rather than GNU binutils. They 2076 should be drop-in replacements, with the addition of arm64 support. 2077 The WITHOUT_ELFTOOLCHAIN_TOOLS= knob may be used to obtain the 2078 binutils tools, if necessary. See 20150805 for updated information. 2079 208020150105: 2081 The default Unbound configuration now enables remote control 2082 using a local socket. Users who have already enabled the 2083 local_unbound service should regenerate their configuration 2084 by running "service local_unbound setup" as root. 2085 208620150102: 2087 The GNU texinfo and GNU info pages have been removed. 2088 To be able to view GNU info pages please install texinfo from ports. 2089 209020141231: 2091 Clang, llvm and lldb have been upgraded to 3.5.0 release. 2092 2093 As of this release, a prerequisite for building clang, llvm and lldb is 2094 a C++11 capable compiler and C++11 standard library. This means that to 2095 be able to successfully build the cross-tools stage of buildworld, with 2096 clang as the bootstrap compiler, your system compiler or cross compiler 2097 should either be clang 3.3 or later, or gcc 4.8 or later, and your 2098 system C++ library should be libc++, or libdstdc++ from gcc 4.8 or 2099 later. 2100 2101 On any standard FreeBSD 10.x or 11.x installation, where clang and 2102 libc++ are on by default (that is, on x86 or arm), this should work out 2103 of the box. 2104 2105 On 9.x installations where clang is enabled by default, e.g. on x86 and 2106 powerpc, libc++ will not be enabled by default, so libc++ should be 2107 built (with clang) and installed first. If both clang and libc++ are 2108 missing, build clang first, then use it to build libc++. 2109 2110 On 8.x and earlier installations, upgrade to 9.x first, and then follow 2111 the instructions for 9.x above. 2112 2113 Sparc64 and mips users are unaffected, as they still use gcc 4.2.1 by 2114 default, and do not build clang. 2115 2116 Many embedded systems are resource constrained, and will not be able to 2117 build clang in a reasonable time, or in some cases at all. In those 2118 cases, cross building bootable systems on amd64 is a workaround. 2119 2120 This new version of clang introduces a number of new warnings, of which 2121 the following are most likely to appear: 2122 2123 -Wabsolute-value 2124 2125 This warns in two cases, for both C and C++: 2126 * When the code is trying to take the absolute value of an unsigned 2127 quantity, which is effectively a no-op, and almost never what was 2128 intended. The code should be fixed, if at all possible. If you are 2129 sure that the unsigned quantity can be safely cast to signed, without 2130 loss of information or undefined behavior, you can add an explicit 2131 cast, or disable the warning. 2132 2133 * When the code is trying to take an absolute value, but the called 2134 abs() variant is for the wrong type, which can lead to truncation. 2135 If you want to disable the warning instead of fixing the code, please 2136 make sure that truncation will not occur, or it might lead to unwanted 2137 side-effects. 2138 2139 -Wtautological-undefined-compare and 2140 -Wundefined-bool-conversion 2141 2142 These warn when C++ code is trying to compare 'this' against NULL, while 2143 'this' should never be NULL in well-defined C++ code. However, there is 2144 some legacy (pre C++11) code out there, which actively abuses this 2145 feature, which was less strictly defined in previous C++ versions. 2146 2147 Squid and openjdk do this, for example. The warning can be turned off 2148 for C++98 and earlier, but compiling the code in C++11 mode might result 2149 in unexpected behavior; for example, the parts of the program that are 2150 unreachable could be optimized away. 2151 215220141222: 2153 The old NFS client and server (kernel options NFSCLIENT, NFSSERVER) 2154 kernel sources have been removed. The .h files remain, since some 2155 utilities include them. This will need to be fixed later. 2156 If "mount -t oldnfs ..." is attempted, it will fail. 2157 If the "-o" option on mountd(8), nfsd(8) or nfsstat(1) is used, 2158 the utilities will report errors. 2159 216020141121: 2161 The handling of LOCAL_LIB_DIRS has been altered to skip addition of 2162 directories to top level SUBDIR variable when their parent 2163 directory is included in LOCAL_DIRS. Users with build systems with 2164 such hierarchies and without SUBDIR entries in the parent 2165 directory Makefiles should add them or add the directories to 2166 LOCAL_DIRS. 2167 216820141109: 2169 faith(4) and faithd(8) have been removed from the base system. Faith 2170 has been obsolete for a very long time. 2171 217220141104: 2173 vt(4), the new console driver, is enabled by default. It brings 2174 support for Unicode and double-width characters, as well as 2175 support for UEFI and integration with the KMS kernel video 2176 drivers. 2177 2178 You may need to update your console settings in /etc/rc.conf, 2179 most probably the keymap. During boot, /etc/rc.d/syscons will 2180 indicate what you need to do. 2181 2182 vt(4) still has issues and lacks some features compared to 2183 syscons(4). See the wiki for up-to-date information: 2184 https://wiki.freebsd.org/Newcons 2185 2186 If you want to keep using syscons(4), you can do so by adding 2187 the following line to /boot/loader.conf: 2188 kern.vty=sc 2189 219020141102: 2191 pjdfstest has been integrated into kyua as an opt-in test suite. 2192 Please see share/doc/pjdfstest/README for more details on how to 2193 execute it. 2194 219520141009: 2196 gperf has been removed from the base system for architectures 2197 that use clang. Ports that require gperf will obtain it from the 2198 devel/gperf port. 2199 220020140923: 2201 pjdfstest has been moved from tools/regression/pjdfstest to 2202 contrib/pjdfstest . 2203 220420140922: 2205 At svn r271982, The default linux compat kernel ABI has been adjusted 2206 to 2.6.18 in support of the linux-c6 compat ports infrastructure 2207 update. If you wish to continue using the linux-f10 compat ports, 2208 add compat.linux.osrelease=2.6.16 to your local sysctl.conf. Users are 2209 encouraged to update their linux-compat packages to linux-c6 during 2210 their next update cycle. 2211 221220140729: 2213 The ofwfb driver, used to provide a graphics console on PowerPC when 2214 using vt(4), no longer allows mmap() of all physical memory. This 2215 will prevent Xorg on PowerPC with some ATI graphics cards from 2216 initializing properly unless x11-servers/xorg-server is updated to 2217 1.12.4_8 or newer. 2218 221920140723: 2220 The xdev targets have been converted to using TARGET and 2221 TARGET_ARCH instead of XDEV and XDEV_ARCH. 2222 222320140719: 2224 The default unbound configuration has been modified to address 2225 issues with reverse lookups on networks that use private 2226 address ranges. If you use the local_unbound service, run 2227 "service local_unbound setup" as root to regenerate your 2228 configuration, then "service local_unbound reload" to load the 2229 new configuration. 2230 223120140709: 2232 The GNU texinfo and GNU info pages are not built and installed 2233 anymore, WITH_INFO knob has been added to allow to built and install 2234 them again. 2235 UPDATE: see 20150102 entry on texinfo's removal 2236 223720140708: 2238 The GNU readline library is now an INTERNALLIB - that is, it is 2239 statically linked into consumers (GDB and variants) in the base 2240 system, and the shared library is no longer installed. The 2241 devel/readline port is available for third party software that 2242 requires readline. 2243 224420140702: 2245 The Itanium architecture (ia64) has been removed from the list of 2246 known architectures. This is the first step in the removal of the 2247 architecture. 2248 224920140701: 2250 Commit r268115 has added NFSv4.1 server support, merged from 2251 projects/nfsv4.1-server. Since this includes changes to the 2252 internal interfaces between the NFS related modules, a full 2253 build of the kernel and modules will be necessary. 2254 __FreeBSD_version has been bumped. 2255 225620140629: 2257 The WITHOUT_VT_SUPPORT kernel config knob has been renamed 2258 WITHOUT_VT. (The other _SUPPORT knobs have a consistent meaning 2259 which differs from the behaviour controlled by this knob.) 2260 226120140619: 2262 Maximal length of the serial number in CTL was increased from 16 to 2263 64 chars, that breaks ABI. All CTL-related tools, such as ctladm 2264 and ctld, need to be rebuilt to work with a new kernel. 2265 226620140606: 2267 The libatf-c and libatf-c++ major versions were downgraded to 0 and 2268 1 respectively to match the upstream numbers. They were out of 2269 sync because, when they were originally added to FreeBSD, the 2270 upstream versions were not respected. These libraries are private 2271 and not yet built by default, so renumbering them should be a 2272 non-issue. However, unclean source trees will yield broken test 2273 programs once the operator executes "make delete-old-libs" after a 2274 "make installworld". 2275 2276 Additionally, the atf-sh binary was made private by moving it into 2277 /usr/libexec/. Already-built shell test programs will keep the 2278 path to the old binary so they will break after "make delete-old" 2279 is run. 2280 2281 If you are using WITH_TESTS=yes (not the default), wipe the object 2282 tree and rebuild from scratch to prevent spurious test failures. 2283 This is only needed once: the misnumbered libraries and misplaced 2284 binaries have been added to OptionalObsoleteFiles.inc so they will 2285 be removed during a clean upgrade. 2286 228720140512: 2288 Clang and llvm have been upgraded to 3.4.1 release. 2289 229020140508: 2291 We bogusly installed src.opts.mk in /usr/share/mk. This file should 2292 be removed to avoid issues in the future (and has been added to 2293 ObsoleteFiles.inc). 2294 229520140505: 2296 /etc/src.conf now affects only builds of the FreeBSD src tree. In the 2297 past, it affected all builds that used the bsd.*.mk files. The old 2298 behavior was a bug, but people may have relied upon it. To get this 2299 behavior back, you can .include /etc/src.conf from /etc/make.conf 2300 (which is still global and isn't changed). This also changes the 2301 behavior of incremental builds inside the tree of individual 2302 directories. Set MAKESYSPATH to ".../share/mk" to do that. 2303 Although this has survived make universe and some upgrade scenarios, 2304 other upgrade scenarios may have broken. At least one form of 2305 temporary breakage was fixed with MAKESYSPATH settings for buildworld 2306 as well... In cases where MAKESYSPATH isn't working with this 2307 setting, you'll need to set it to the full path to your tree. 2308 2309 One side effect of all this cleaning up is that bsd.compiler.mk 2310 is no longer implicitly included by bsd.own.mk. If you wish to 2311 use COMPILER_TYPE, you must now explicitly include bsd.compiler.mk 2312 as well. 2313 231420140430: 2315 The lindev device has been removed since /dev/full has been made a 2316 standard device. __FreeBSD_version has been bumped. 2317 231820140424: 2319 The knob WITHOUT_VI was added to the base system, which controls 2320 building ex(1), vi(1), etc. Older releases of FreeBSD required ex(1) 2321 in order to reorder files share/termcap and didn't build ex(1) as a 2322 build tool, so building/installing with WITH_VI is highly advised for 2323 build hosts for older releases. 2324 2325 This issue has been fixed in stable/9 and stable/10 in r277022 and 2326 r276991, respectively. 2327 232820140418: 2329 The YES_HESIOD knob has been removed. It has been obsolete for 2330 a decade. Please move to using WITH_HESIOD instead or your builds 2331 will silently lack HESIOD. 2332 233320140405: 2334 The uart(4) driver has been changed with respect to its handling 2335 of the low-level console. Previously the uart(4) driver prevented 2336 any process from changing the baudrate or the CLOCAL and HUPCL 2337 control flags. By removing the restrictions, operators can make 2338 changes to the serial console port without having to reboot. 2339 However, when getty(8) is started on the serial device that is 2340 associated with the low-level console, a misconfigured terminal 2341 line in /etc/ttys will now have a real impact. 2342 Before upgrading the kernel, make sure that /etc/ttys has the 2343 serial console device configured as 3wire without baudrate to 2344 preserve the previous behaviour. E.g: 2345 ttyu0 "/usr/libexec/getty 3wire" vt100 on secure 2346 234720140306: 2348 Support for libwrap (TCP wrappers) in rpcbind was disabled by default 2349 to improve performance. To re-enable it, if needed, run rpcbind 2350 with command line option -W. 2351 235220140226: 2353 Switched back to the GPL dtc compiler due to updates in the upstream 2354 dts files not being supported by the BSDL dtc compiler. You will need 2355 to rebuild your kernel toolchain to pick up the new compiler. Core dumps 2356 may result while building dtb files during a kernel build if you fail 2357 to do so. Set WITHOUT_GPL_DTC if you require the BSDL compiler. 2358 235920140216: 2360 Clang and llvm have been upgraded to 3.4 release. 2361 236220140216: 2363 The nve(4) driver has been removed. Please use the nfe(4) driver 2364 for NVIDIA nForce MCP Ethernet adapters instead. 2365 236620140212: 2367 An ABI incompatibility crept into the libc++ 3.4 import in r261283. 2368 This could cause certain C++ applications using shared libraries built 2369 against the previous version of libc++ to crash. The incompatibility 2370 has now been fixed, but any C++ applications or shared libraries built 2371 between r261283 and r261801 should be recompiled. 2372 237320140204: 2374 OpenSSH will now ignore errors caused by kernel lacking of Capsicum 2375 capability mode support. Please note that enabling the feature in 2376 kernel is still highly recommended. 2377 237820140131: 2379 OpenSSH is now built with sandbox support, and will use sandbox as 2380 the default privilege separation method. This requires Capsicum 2381 capability mode support in kernel. 2382 238320140128: 2384 The libelf and libdwarf libraries have been updated to newer 2385 versions from upstream. Shared library version numbers for 2386 these two libraries were bumped. Any ports or binaries 2387 requiring these two libraries should be recompiled. 2388 __FreeBSD_version is bumped to 1100006. 2389 239020140110: 2391 If a Makefile in a tests/ directory was auto-generating a Kyuafile 2392 instead of providing an explicit one, this would prevent such 2393 Makefile from providing its own Kyuafile in the future during 2394 NO_CLEAN builds. This has been fixed in the Makefiles but manual 2395 intervention is needed to clean an objdir if you use NO_CLEAN: 2396 # find /usr/obj -name Kyuafile | xargs rm -f 2397 239820131213: 2399 The behavior of gss_pseudo_random() for the krb5 mechanism 2400 has changed, for applications requesting a longer random string 2401 than produced by the underlying enctype's pseudo-random() function. 2402 In particular, the random string produced from a session key of 2403 enctype aes256-cts-hmac-sha1-96 or aes256-cts-hmac-sha1-96 will 2404 be different at the 17th octet and later, after this change. 2405 The counter used in the PRF+ construction is now encoded as a 2406 big-endian integer in accordance with RFC 4402. 2407 __FreeBSD_version is bumped to 1100004. 2408 240920131108: 2410 The WITHOUT_ATF build knob has been removed and its functionality 2411 has been subsumed into the more generic WITHOUT_TESTS. If you were 2412 using the former to disable the build of the ATF libraries, you 2413 should change your settings to use the latter. 2414 241520131025: 2416 The default version of mtree is nmtree which is obtained from 2417 NetBSD. The output is generally the same, but may vary 2418 slightly. If you found you need identical output adding 2419 "-F freebsd9" to the command line should do the trick. For the 2420 time being, the old mtree is available as fmtree. 2421 242220131014: 2423 libbsdyml has been renamed to libyaml and moved to /usr/lib/private. 2424 This will break ports-mgmt/pkg. Rebuild the port, or upgrade to pkg 2425 1.1.4_8 and verify bsdyml not linked in, before running "make 2426 delete-old-libs": 2427 # make -C /usr/ports/ports-mgmt/pkg build deinstall install clean 2428 or 2429 # pkg install pkg; ldd /usr/local/sbin/pkg | grep bsdyml 2430 243120131010: 2432 The stable/10 branch has been created in subversion from head 2433 revision r256279. 2434 2435COMMON ITEMS: 2436 2437 General Notes 2438 ------------- 2439 Sometimes, obscure build problems are the result of environment 2440 poisoning. This can happen because the make utility reads its 2441 environment when searching for values for global variables. To run 2442 your build attempts in an "environmental clean room", prefix all make 2443 commands with 'env -i '. See the env(1) manual page for more details. 2444 Occasionally a build failure will occur with "make -j" due to a race 2445 condition. If this happens try building again without -j, and please 2446 report a bug if it happens consistently. 2447 2448 When upgrading from one major version to another it is generally best to 2449 upgrade to the latest code in the currently installed branch first, then 2450 do an upgrade to the new branch. This is the best-tested upgrade path, 2451 and has the highest probability of being successful. Please try this 2452 approach if you encounter problems with a major version upgrade. Since 2453 the stable 4.x branch point, one has generally been able to upgrade from 2454 anywhere in the most recent stable branch to head / current (or even the 2455 last couple of stable branches). See the top of this file when there's 2456 an exception. 2457 2458 The update process will emit an error on an attempt to perform a build 2459 or install from a FreeBSD version below the earliest supported version. 2460 When updating from an older version the update should be performed one 2461 major release at a time, including running `make delete-old` at each 2462 step. 2463 2464 When upgrading a live system, having a root shell around before 2465 installing anything can help undo problems. Not having a root shell 2466 around can lead to problems if pam has changed too much from your 2467 starting point to allow continued authentication after the upgrade. 2468 2469 This file should be read as a log of events. When a later event changes 2470 information of a prior event, the prior event should not be deleted. 2471 Instead, a pointer to the entry with the new information should be 2472 placed in the old entry. Readers of this file should also sanity check 2473 older entries before relying on them blindly. Authors of new entries 2474 should write them with this in mind. 2475 2476 ZFS notes 2477 --------- 2478 When upgrading the boot ZFS pool to a new version, always follow 2479 these two steps: 2480 2481 1.) recompile and reinstall the ZFS boot loader and boot block 2482 (this is part of "make buildworld" and "make installworld") 2483 2484 2.) update the ZFS boot block on your boot drive 2485 2486 The following example updates the ZFS boot block on the 2487 freebsd-boot partition of a GPT partitioned drive ada0: 2488 "gpart bootcode -p /boot/gptzfsboot -i $N ada0" 2489 The value $N will typically be 1 (if booting from BIOS) or 2 (if 2490 booting from EFI). 2491 2492 Non-boot pools do not need these updates. 2493 2494 To build a kernel 2495 ----------------- 2496 If you are updating from a prior version of FreeBSD (even one just 2497 a few days old), you should follow this procedure. It is the most 2498 failsafe as it uses a /usr/obj tree with a fresh mini-buildworld, 2499 2500 make kernel-toolchain 2501 make -DALWAYS_CHECK_MAKE buildkernel KERNCONF=YOUR_KERNEL_HERE 2502 make -DALWAYS_CHECK_MAKE installkernel KERNCONF=YOUR_KERNEL_HERE 2503 2504 To test a kernel once 2505 --------------------- 2506 If you just want to boot a kernel once (because you are not sure 2507 if it works, or if you want to boot a known bad kernel to provide 2508 debugging information) run 2509 make installkernel KERNCONF=YOUR_KERNEL_HERE KODIR=/boot/testkernel 2510 nextboot -k testkernel 2511 2512 To rebuild everything and install it on the current system. 2513 ----------------------------------------------------------- 2514 # Note: sometimes if you are running current you gotta do more than 2515 # is listed here if you are upgrading from a really old current. 2516 2517 <make sure you have good level 0 dumps> 2518 make buildworld 2519 make buildkernel KERNCONF=YOUR_KERNEL_HERE 2520 make installkernel KERNCONF=YOUR_KERNEL_HERE 2521 [1] 2522 <reboot in single user> [3] 2523 etcupdate -p [5] 2524 make installworld 2525 etcupdate -B [4] 2526 make delete-old [6] 2527 <reboot> 2528 2529 To cross-install current onto a separate partition 2530 -------------------------------------------------- 2531 # In this approach we use a separate partition to hold 2532 # current's root, 'usr', and 'var' directories. A partition 2533 # holding "/", "/usr" and "/var" should be about 2GB in 2534 # size. 2535 2536 <make sure you have good level 0 dumps> 2537 <boot into -stable> 2538 make buildworld 2539 make buildkernel KERNCONF=YOUR_KERNEL_HERE 2540 <maybe newfs current's root partition> 2541 <mount current's root partition on directory ${CURRENT_ROOT}> 2542 make installworld DESTDIR=${CURRENT_ROOT} -DDB_FROM_SRC 2543 make distribution DESTDIR=${CURRENT_ROOT} # if newfs'd 2544 make installkernel KERNCONF=YOUR_KERNEL_HERE DESTDIR=${CURRENT_ROOT} 2545 cp /etc/fstab ${CURRENT_ROOT}/etc/fstab # if newfs'd 2546 <edit ${CURRENT_ROOT}/etc/fstab to mount "/" from the correct partition> 2547 <reboot into current> 2548 <do a "native" rebuild/install as described in the previous section> 2549 <maybe install compatibility libraries from ports/misc/compat*> 2550 <reboot> 2551 2552 2553 To upgrade in-place from stable to current 2554 ---------------------------------------------- 2555 <make sure you have good level 0 dumps> 2556 make buildworld [9] 2557 make buildkernel KERNCONF=YOUR_KERNEL_HERE [8] 2558 make installkernel KERNCONF=YOUR_KERNEL_HERE 2559 [1] 2560 <reboot in single user> [3] 2561 etcupdate -p [5] 2562 make installworld 2563 etcupdate -B [4] 2564 make delete-old [6] 2565 <reboot> 2566 2567 Make sure that you've read the UPDATING file to understand the 2568 tweaks to various things you need. At this point in the life 2569 cycle of current, things change often and you are on your own 2570 to cope. The defaults can also change, so please read ALL of 2571 the UPDATING entries. 2572 2573 Also, if you are tracking -current, you must be subscribed to 2574 freebsd-current@freebsd.org. Make sure that before you update 2575 your sources that you have read and understood all the recent 2576 messages there. If in doubt, please track -stable which has 2577 much fewer pitfalls. 2578 2579 [1] If you have third party modules, such as vmware, you should disable 2580 them at this point so they don't crash your system on 2581 reboot. Alternatively, you should rebuild all the modules you have in 2582 your system and install them as well. If you are running -current, you 2583 should seriously consider placing all sources to all the modules for 2584 your system (or symlinks to them) in /usr/local/sys/modules so this 2585 happens automatically. If all your modules come from ports, then adding 2586 the port origin directories to PORTS_MODULES instead is also automatic 2587 and effective, eg: 2588 PORTS_MODULES+=x11/nvidia-driver 2589 2590 [3] From the bootblocks, boot -s, and then do 2591 fsck -p 2592 mount -u / 2593 mount -a 2594 sh /etc/rc.d/zfs start # mount zfs filesystem, if needed 2595 cd src # full path to source 2596 adjkerntz -i # if CMOS is wall time 2597 Also, when doing a major release upgrade, it is required that you boot 2598 into single user mode to do the installworld. 2599 2600 [4] Note: This step is non-optional. Failure to do this step 2601 can result in a significant reduction in the functionality of the 2602 system. Attempting to do it by hand is not recommended and those 2603 that pursue this avenue should read this file carefully, as well 2604 as the archives of freebsd-current and freebsd-hackers mailing lists 2605 for potential gotchas. See etcupdate(8) for more information. 2606 2607 [5] Usually this step is a no-op. However, from time to time 2608 you may need to do this if you get unknown user in the following 2609 step. 2610 2611 [6] This only deletes old files and directories. Old libraries 2612 can be deleted by "make delete-old-libs", but you have to make 2613 sure that no program is using those libraries anymore. 2614 2615 [8] The new kernel must be able to run existing binaries used by an 2616 installworld. When upgrading across major versions, the new kernel's 2617 configuration must include the correct COMPAT_FREEBSD<n> option for 2618 existing binaries (e.g. COMPAT_FREEBSD11 to run 11.x binaries). Failure 2619 to do so may leave you with a system that is hard to boot to recover. A 2620 GENERIC kernel will include suitable compatibility options to run 2621 binaries from older branches. Note that the ability to run binaries 2622 from unsupported branches is not guaranteed. 2623 2624 Make sure that you merge any new devices from GENERIC since the 2625 last time you updated your kernel config file. Options also 2626 change over time, so you may need to adjust your custom kernels 2627 for these as well. 2628 2629 [9] If CPUTYPE is defined in your /etc/make.conf, make sure to use the 2630 "?=" instead of the "=" assignment operator, so that buildworld can 2631 override the CPUTYPE if it needs to. 2632 2633 MAKEOBJDIRPREFIX must be defined in an environment variable, and 2634 not on the command line, or in /etc/make.conf. buildworld will 2635 warn if it is improperly defined. 2636FORMAT: 2637 2638This file contains a list, in reverse chronological order, of major 2639breakages in tracking -current. It is not guaranteed to be a complete 2640list of such breakages, and only contains entries since September 23, 2011. 2641If you need to see UPDATING entries from before that date, you will need 2642to fetch an UPDATING file from an older FreeBSD release. 2643 2644Copyright information: 2645 2646Copyright 1998-2009 M.
