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 3020210608: 31 The vendor/openzfs branch was renamed to vendor/openzfs/legacy to 32 start tracking OpenZFS upstream more closely. Please see 33https://lists.freebsd.org/archives/freebsd-current/2021-June/000153.html 34 for details on how to correct any errors that might result. The 35 short version is that you need to remove the old branch locally: 36 git update-ref -d refs/remotes/freebsd/vendor/openzfs 37 (assuming your upstream origin is named 'freebsd'). 38 3920210525: 40 Commits 17accc08ae15 and de102f870501 add new files to LinuxKPI 41 which break drm-kmod. In addition various other additions where 42 comitted. Bump __FreeBSD_version to 1400015 to be able to detect this. 43 4420210513: 45 Commit ca179c4d74f2 changed the package in which the OpenSSL 46 libraries and utilities are packaged. 47 It is recommended for pkgbase user to do: 48 pkg install -f FreeBSD-openssl 49 before pkg upgrade otherwise some dependencies might not be met 50 and pkg will stop working as libssl will not be present anymore 51 on the system. 52 5320210426: 54 Commit 875977314881 changed the internal KAPI between 55 the nfsd and nfscommon modules. As such these modules 56 need to be rebuilt from sources. 57 Without this patch in your NFSv4.1/4.2 server, enabling 58 delegations by setting vfs.nfsd.issue_delegations non-zero 59 is not recommended. 60 6120210411: 62 Commit 7763814fc9c2 changed the internal KAPI between 63 the krpc and NFS. As such, the krpc, nfscommon and 64 nfscl modules must all be rebuilt from sources. 65 Without this patch, NFSv4.1/4.2 mounts should not 66 be done with the nfscbd(8) daemon running, to avoid 67 needing a working back channel for server->client RPCs. 68 6920210330: 70 Commit 01ae8969a9ee fixed the NFSv4.1/4.2 server so that it 71 handles binding of the back channel as required by RFC5661. 72 Until this patch is in your server, avoid use of the "nconnects" 73 mount option for Linux NFSv4.1/4.2 mounts. 74 7520210225: 76 For 64-bit architectures the base system is now built with Position 77 Independent Executable (PIE) support enabled by default. It may be 78 disabled using the WITHOUT_PIE knob. A clean build is required. 79 8020210128: 81 Various LinuxKPI functionality was added which conflicts with DRM. 82 Please update your drm-kmod port to after the __FreeBSD_verison 1400003 83 update. 84 8520210108: 86 PC Card attachments for all devices have been removed. In the case of 87 wi and cmx, the entire drivers were removed because they were only 88 PC Card devices. FreeBSD_version 1300134 should be used for this 89 since it was bumped so recently. 90 9120210107: 92 Transport-independent parts of HID support have been split off the USB 93 code in to separate subsystem. Kernel configs which include one of 94 ums, ukbd, uhid, atp, wsp, wmt, uaudio, ugold or ucycom drivers should 95 be updated with adding of "device hid" line. 96 9720210105: 98 ncurses installation has been modified to only keep the widechar 99 enabled version. Incremental build is broken for that change, so it 100 requires a clean build. 101 10220201223: 103 The FreeBSD project has migrated from Subversion to Git. Temporary 104 instructions can be found at 105 https://github.com/bsdimp/freebsd-git-docs/blob/main/src-cvt.md 106 and other documents in that repo. 107 10820201216: 109 The services database has been updated to cover more of the basic 110 services expected in a modern system. The database is big enough 111 that it will cause issues in mergemaster in Releases previous to 112 12.2 and 11.3, or in very old current systems from before r358154. 113 11420201215: 115 Obsolete in-tree GDB 6.1.1 has been removed. GDB (including kgdb) 116 may be installed from ports or packages. 117 11820201124: 119 ping6 has been merged into ping. It can now be called as "ping -6". 120 See ping(8) for details. 121 12220201108: 123 Default value of net.add_addr_allfibs has been changed to 0. 124 If you have multi-fib configuration and rely on existence of all 125 interface routes in every fib, you need to set the above sysctl to 1. 126 12720201030: 128 The internal pre-processor in the calendar(1) program has been 129 extended to support more C pre-processor commands (e.g. #ifdef, #else, 130 and #undef) and to detect unbalanced conditional statements. 131 Error messages have been extended to include the filename and line 132 number if processing stops to help fixing malformed data files. 133 13420201026: 135 All the data files for the calendar(1) program, except calendar.freebsd, 136 have been moved to the deskutils/calendar-data port, much like the 137 jewish calendar entries were moved to deskutils/hebcal years ago. After 138 make delete-old-files, you need to install it to retain full 139 functionality. calendar(1) will issue a reminder for files it can't 140 find. 141 14220200923: 143 LINT files are no longer generated. We now include the relevant NOTES 144 files. Note: This may cause conflicts with updating in some cases. 145 find sys -name LINT\* -delete 146 is suggested across this commit to remove the generated LINT files. 147 148 If you have tried to update with generated files there, the svn 149 command you want to un-auger the tree is 150 cd sys/amd64/conf 151 svn revert -R . 152 and then do the above find from the top level. Substitute 'amd64' 153 above with where the error message indicates a conflict. 154 15520200824: 156 OpenZFS support has been integrated. Do not upgrade root pools until 157 the loader is updated to support zstd. Furthermore, we caution against 158 'zpool upgrade' for the next few weeks. The change should be transparent 159 unless you want to use new features. 160 161 Not all "NO_CLEAN" build scenarios work across these changes. Many 162 scenarios have been tested and fixed, but rebuilding kernels without 163 rebuilding world may fail. 164 165 The ZFS cache file has moved from /boot to /etc to match the OpenZFS 166 upstream default. A fallback to /boot has been added for mountroot. 167 168 Pool auto import behavior at boot has been moved from the kernel module 169 to an explicit "zpool import -a" in one of the rc scripts enabled by 170 zfs_enable=YES. This means your non-root zpools won't auto import until 171 you upgrade your /etc/rc.d files. 172 17320200824: 174 The resume code now notifies devd with the 'kernel' system 175 rather than the old 'kern' subsystem to be consistent with 176 other use. The old notification will be created as well, but 177 will be removed prior to FreeBSD 14.0. 178 17920200821: 180 r362275 changed the internal API between the kernel RPC and the 181 NFS modules. As such, all the modules must be recompiled from 182 sources. 183 18420200817: 185 r364330 modified the internal API used between the NFS modules. 186 As such, all the NFS modules must be re-compiled from sources. 187 18820200816: 189 Clang, llvm, lld, lldb, compiler-rt, libc++, libunwind and openmp have 190 been upgraded to 11.0.0. Please see the 20141231 entry below for 191 information about prerequisites and upgrading, if you are not already 192 using clang 3.5.0 or higher. 193 19420200810: 195 r364092 modified the internal ABI used between the kernel NFS 196 modules. As such, all of these modules need to be rebuilt 197 from sources, so a version bump was done. 198 19920200807: 200 Makefile.inc has been updated to work around the issue documented in 201 20200729. It was a case where the optimization of using symbolic links 202 to point to binaries created a situation where we'd run new binaries 203 with old libraries starting midway through the installworld process. 204 20520200729: 206 r363679 has redefined some undefined behavior in regcomp(3); notably, 207 extraneous escapes of most ordinary characters will no longer be 208 accepted. An exp-run has identified all of the problems with this in 209 ports, but other non-ports software may need extra escapes removed to 210 continue to function. 211 212 Because of this change, installworld may encounter the following error 213 from rtld: Undefined symbol "regcomp@FBSD_1.6" -- It is imperative that 214 you do not halt installworld. Instead, let it run to completion (whether 215 successful or not) and run installworld once more. 216 21720200627: 218 A new implementation of bc and dc has been imported in r362681. This 219 implementation corrects non-conformant behavior of the previous bc 220 and adds GNU bc compatible options. It offers a number of extensions, 221 is much faster on large values, and has support for message catalogs 222 (a number of languages are already supported, contributions of further 223 languages welcome). The option WITHOUT_GH_BC can be used to build the 224 world with the previous versions of bc and dc. 225 22620200625: 227 r362639 changed the internal API used between the NFS kernel modules. 228 As such, they all need to be rebuilt from sources. 229 23020200613: 231 r362158 changed the arguments for VFS_CHECKEXP(). As such, any 232 out of tree file systems need to be modified and rebuilt. 233 Also, any file systems that are modules must be rebuilt. 234 23520200604: 236 read(2) of a directory fd is now rejected by default. root may 237 re-enable it for system root only on non-ZFS filesystems with the 238 security.bsd.allow_read_dir sysctl(8) MIB if 239 security.bsd.suser_enabled=1. 240 241 It may be advised to setup aliases for grep to default to `-d skip` if 242 commonly non-recursively grepping a list that includes directories and 243 the potential for the resulting stderr output is not tolerable. Example 244 aliases are now installed, commented out, in /root/.cshrc and 245 /root/.shrc. 246 24720200523: 248 Clang, llvm, lld, lldb, compiler-rt, libc++, libunwind and openmp have 249 been upgraded to 10.0.1. Please see the 20141231 entry below for 250 information about prerequisites and upgrading, if you are not already 251 using clang 3.5.0 or higher. 252 25320200512: 254 Support for obsolete compilers has been removed from the build system. 255 Clang 6 and GCC 6.4 are the minimum supported versions. 256 25720200424: 258 closefrom(2) has been moved under COMPAT12, and replaced in libc with a 259 stub that calls close_range(2). If using a custom kernel configuration, 260 you may want to ensure that the COMPAT_FREEBSD12 option is included, as 261 a slightly older -CURRENT userland and older FreeBSD userlands may not 262 be functional without closefrom(2). 263 26420200414: 265 Upstream DTS from Linux 5.6 was merged and they now have the SID 266 and THS (Secure ID controller and THermal Sensor) node present. 267 The DTB overlays have now been removed from the tree for the H3/H5 and 268 A64 SoCs and the aw_sid and aw_thermal driver have been updated to 269 deal with upstream DTS. If you are using those overlays you need to 270 remove them from loader.conf and update the DTBs on the FAT partition. 271 27220200310: 273 Clang, llvm, lld, lldb, compiler-rt, libc++, libunwind and openmp have 274 been upgraded to 10.0.0. Please see the 20141231 entry below for 275 information about prerequisites and upgrading, if you are not already 276 using clang 3.5.0 or higher. 277 27820200309: 279 The amd(8) automount daemon has been removed from the source tree. 280 As of FreeBSD 10.1 autofs(5) is the preferred tool for automounting. 281 amd is still available in the sysutils/am-utils port. 282 28320200301: 284 Removed brooktree driver (bktr.4) from the tree. 285 28620200229: 287 The WITH_GPL_DTC option has been removed. The BSD-licenced device tree 288 compiler in usr.bin/dtc is used on all architectures which use dtc, and 289 the GPL dtc is available (if needed) from the sysutils/dtc port. 290 29120200229: 292 The WITHOUT_LLVM_LIBUNWIND option has been removed. LLVM's libunwind 293 is used by all supported CPU architectures. 294 29520200229: 296 GCC 4.2.1 has been removed from the tree. The WITH_GCC, 297 WITH_GCC_BOOTSTRAP, and WITH_GNUCXX options are no longer available. 298 Users who wish to build FreeBSD with GCC must use the external toolchain 299 ports or packages. 300 30120200220: 302 ncurses has been updated to a newer version (6.2-20200215). Given the ABI 303 has changed, users will have to rebuild all the ports that are linked to 304 ncurses. 305 30620200217: 307 The size of struct vnet and the magic cookie have changed. 308 Users need to recompile libkvm and all modules using VIMAGE 309 together with their new kernel. 310 31120200212: 312 Defining the long deprecated NO_CTF, NO_DEBUG_FILES, NO_INSTALLLIB, 313 NO_MAN, NO_PROFILE, and NO_WARNS variables is now an error. Update 314 your Makefiles and scripts to define MK_<var>=no instead as required. 315 316 One exception to this is that program or library Makefiles should 317 define MAN to empty rather than setting MK_MAN=no. 318 31920200108: 320 Clang/LLVM is now the default compiler and LLD the default 321 linker for riscv64. 322 32320200107: 324 make universe no longer uses GCC 4.2.1 on any architectures. 325 Architectures not supported by in-tree Clang/LLVM require an 326 external toolchain package. 327 32820200104: 329 GCC 4.2.1 is now not built by default, as part of the GCC 4.2.1 330 retirement plan. Specifically, the GCC, GCC_BOOTSTRAP, and GNUCXX 331 options default to off for all supported CPU architectures. As a 332 short-term transition aid they may be enabled via WITH_* options. 333 GCC 4.2.1 is expected to be removed from the tree on 2020-03-31. 334 33520200102: 336 Support for armv5 has been disconnected and is being removed. The 337 machine combination MACHINE=arm MACHINE_ARCH=arm is no longer valid. 338 You must now use a MACHINE_ARCH of armv6 or armv7. The default 339 MACHINE_ARCH for MACHINE=arm is now armv7. 340 34120191226: 342 Clang/LLVM is now the default compiler for all powerpc architectures. 343 LLD is now the default linker for powerpc64. The change for powerpc64 344 also includes a change to the ELFv2 ABI, incompatible with the existing 345 ABI. 346 34720191226: 348 Kernel-loadable random(4) modules are no longer unloadable. 349 35020191222: 351 Clang, llvm, lld, lldb, compiler-rt, libc++, libunwind and openmp have 352 been upgraded to 9.0.1. Please see the 20141231 entry below for 353 information about prerequisites and upgrading, if you are not already 354 using clang 3.5.0 or higher. 355 35620191212: 357 r355677 has modified the internal interface used between the 358 NFS modules in the kernel. As such, they must all be upgraded 359 simultaneously. I will do a version bump for this. 360 36120191205: 362 The root certificates of the Mozilla CA Certificate Store have been 363 imported into the base system and can be managed with the certctl(8) 364 utility. If you have installed the security/ca_root_nss port or package 365 with the ETCSYMLINK option (the default), be advised that there may be 366 differences between those included in the port and those included in 367 base due to differences in nss branch used as well as general update 368 frequency. Note also that certctl(8) cannot manage certs in the 369 format used by the security/ca_root_nss port. 370 37120191120: 372 The amd(8) automount daemon has been disabled by default, and will be 373 removed in the future. As of FreeBSD 10.1 the autofs(5) is available 374 for automounting. 375 37620191107: 377 The nctgpio and wbwd drivers have been moved to the superio bus. 378 If you have one of these drivers in a kernel configuration, then 379 you should add device superio to it. If you use one of these drivers 380 as a module and you compile a custom set of modules, then you should 381 add superio to the set. 382 38320191021: 384 KPIs for network drivers to access interface addresses have changed. 385 Users need to recompile NIC driver modules together with kernel. 386 38720191021: 388 The net.link.tap.user_open sysctl no longer prevents user opening of 389 already created /dev/tapNN devices. Access is still controlled by 390 node permissions, just like tun devices. The net.link.tap.user_open 391 sysctl is now used only to allow users to perform devfs cloning of 392 tap devices, and the subsequent open may not succeed if the user is not 393 in the appropriate group. This sysctl may be deprecated/removed 394 completely in the future. 395 39620191009: 397 mips, powerpc, and sparc64 are no longer built as part of 398 universe / tinderbox unless MAKE_OBSOLETE_GCC is defined. If 399 not defined, mips, powerpc, and sparc64 builds will look for 400 the xtoolchain binaries and if installed use them for universe 401 builds. As llvm 9.0 becomes vetted for these architectures, they 402 will be removed from the list. 403 40420191009: 405 Clang, llvm, lld, lldb, compiler-rt, libc++, libunwind and openmp have 406 been upgraded to 9.0.0. Please see the 20141231 entry below for 407 information about prerequisites and upgrading, if you are not already 408 using clang 3.5.0 or higher. 409 41020191003: 411 The hpt27xx, hptmv, hptnr, and hptrr drivers have been removed from 412 GENERIC. They are available as modules and can be loaded by adding 413 to /boot/loader.conf hpt27xx_load="YES", hptmv_load="YES", 414 hptnr_load="YES", or hptrr_load="YES", respectively. 415 41620190913: 417 ntpd no longer by default locks its pages in memory, allowing them 418 to be paged out by the kernel. Use rlimit memlock to restore 419 historic BSD behaviour. For example, add "rlimit memlock 32" 420 to ntp.conf to lock up to 32 MB of ntpd address space in memory. 421 42220190823: 423 Several of ping6's options have been renamed for better consistency 424 with ping. If you use any of -ARWXaghmrtwx, you must update your 425 scripts. See ping6(8) for details. 426 42720190727: 428 The vfs.fusefs.sync_unmount and vfs.fusefs.init_backgrounded sysctls 429 and the "-o sync_unmount" and "-o init_backgrounded" mount options have 430 been removed from mount_fusefs(8). You can safely remove them from 431 your scripts, because they had no effect. 432 433 The vfs.fusefs.fix_broken_io, vfs.fusefs.sync_resize, 434 vfs.fusefs.refresh_size, vfs.fusefs.mmap_enable, 435 vfs.fusefs.reclaim_revoked, and vfs.fusefs.data_cache_invalidate 436 sysctls have been removed. If you felt the need to set any of them to 437 a non-default value, please tell asomers@FreeBSD.org why. 438 43920190713: 440 Default permissions on the /var/account/acct file (and copies of it 441 rotated by periodic daily scripts) are changed from 0644 to 0640 442 because the file contains sensitive information that should not be 443 world-readable. If the /var/account directory must be created by 444 rc.d/accounting, the mode used is now 0750. Admins who use the 445 accounting feature are encouraged to change the mode of an existing 446 /var/account directory to 0750 or 0700. 447 44820190620: 449 Entropy collection and the /dev/random device are no longer optional 450 components. The "device random" option has been removed. 451 Implementations of distilling algorithms can still be made loadable 452 with "options RANDOM_LOADABLE" (e.g., random_fortuna.ko). 453 45420190612: 455 Clang, llvm, lld, lldb, compiler-rt, libc++, libunwind and openmp have 456 been upgraded to 8.0.1. Please see the 20141231 entry below for 457 information about prerequisites and upgrading, if you are not already 458 using clang 3.5.0 or higher. 459 46020190608: 461 A fix was applied to i386 kernel modules to avoid panics with 462 dpcpu or vnet. Users need to recompile i386 kernel modules 463 having pcpu or vnet sections or they will refuse to load. 464 46520190513: 466 User-wired pages now have their own counter, 467 vm.stats.vm.v_user_wire_count. The vm.max_wired sysctl was renamed 468 to vm.max_user_wired and changed from an unsigned int to an unsigned 469 long. bhyve VMs wired with the -S are now subject to the user 470 wiring limit; the vm.max_user_wired sysctl may need to be tuned to 471 avoid running into the limit. 472 47320190507: 474 The IPSEC option has been removed from GENERIC. Users requiring 475 ipsec(4) must now load the ipsec(4) kernel module. 476 47720190507: 478 The tap(4) driver has been folded into tun(4), and the module has been 479 renamed to tuntap. You should update any kld_list="if_tap" or 480 kld_list="if_tun" entries in /etc/rc.conf, if_tap_load="YES" or 481 if_tun_load="YES" entries in /boot/loader.conf to load the if_tuntap 482 module instead, and "device tap" or "device tun" entries in kernel 483 config files to select the tuntap device instead. 484 48520190418: 486 The following knobs have been added related to tradeoffs between 487 safe use of the random device and availability in the absence of 488 entropy: 489 490 kern.random.initial_seeding.bypass_before_seeding: tunable; set 491 non-zero to bypass the random device prior to seeding, or zero to 492 block random requests until the random device is initially seeded. 493 For now, set to 1 (unsafe) by default to restore pre-r346250 boot 494 availability properties. 495 496 kern.random.initial_seeding.read_random_bypassed_before_seeding: 497 read-only diagnostic sysctl that is set when bypass is enabled and 498 read_random(9) is bypassed, to enable programmatic handling of this 499 initial condition, if desired. 500 501 kern.random.initial_seeding.arc4random_bypassed_before_seeding: 502 Similar to the above, but for for arc4random(9) initial seeding. 503 504 kern.random.initial_seeding.disable_bypass_warnings: tunable; set 505 non-zero to disable warnings in dmesg when the same conditions are 506 met as for the diagnostic sysctls above. Defaults to zero, i.e., 507 produce warnings in dmesg when the conditions are met. 508 50920190416: 510 The loadable random module KPI has changed; the random_infra_init() 511 routine now requires a 3rd function pointer for a bool (*)(void) 512 method that returns true if the random device is seeded (and 513 therefore unblocked). 514 51520190404: 516 r345895 reverts r320698. This implies that an nfsuserd(8) daemon 517 built from head sources between r320757 (July 6, 2017) and 518 r338192 (Aug. 22, 2018) will not work unless the "-use-udpsock" 519 is added to the command line. 520 nfsuserd daemons built from head sources that are post-r338192 are 521 not affected and should continue to work. 522 52320190320: 524 The fuse(4) module has been renamed to fusefs(4) for consistency with 525 other filesystems. You should update any kld_load="fuse" entries in 526 /etc/rc.conf, fuse_load="YES" entries in /boot/loader.conf, and 527 "options FUSE" entries in kernel config files. 528 52920190304: 530 Clang, llvm, lld, lldb, compiler-rt and libc++ have been upgraded to 531 8.0.0. Please see the 20141231 entry below for information about 532 prerequisites and upgrading, if you are not already using clang 3.5.0 533 or higher. 534 53520190226: 536 geom_uzip(4) depends on the new module xz. If geom_uzip is statically 537 compiled into your custom kernel, add 'device xz' statement to the 538 kernel config. 539 54020190219: 541 drm and drm2 have been removed from the tree. Please see 542 https://wiki.freebsd.org/Graphics for the latest information on 543 migrating to the drm ports. 544 54520190131: 546 Iflib is no longer unconditionally compiled into the kernel. Drivers 547 using iflib and statically compiled into the kernel, now require 548 the 'device iflib' config option. For the same drivers loaded as 549 modules on kernels not having 'device iflib', the iflib.ko module 550 is loaded automatically. 551 55220190125: 553 The IEEE80211_AMPDU_AGE and AH_SUPPORT_AR5416 kernel configuration 554 options no longer exist since r343219 and r343427 respectively; 555 nothing uses them, so they should be just removed from custom 556 kernel config files. 557 55820181230: 559 r342635 changes the way efibootmgr(8) works by requiring users to add 560 the -b (bootnum) parameter for commands where the bootnum was previously 561 specified with each option. For example 'efibootmgr -B 0001' is now 562 'efibootmgr -B -b 0001'. 563 56420181220: 565 r342286 modifies the NFSv4 server so that it obeys vfs.nfsd.nfs_privport 566 in the same as it is applied to NFSv2 and 3. This implies that NFSv4 567 servers that have vfs.nfsd.nfs_privport set will only allow mounts 568 from clients using a reserved port#. Since both the FreeBSD and Linux 569 NFSv4 clients use reserved port#s by default, this should not affect 570 most NFSv4 mounts. 571 57220181219: 573 The XLP config has been removed. We can't support 64-bit atomics in this 574 kernel because it is running in 32-bit mode. XLP users must transition 575 to running a 64-bit kernel (XLP64 or XLPN32). 576 577 The mips GXEMUL support has been removed from FreeBSD. MALTA* + qemu is 578 the preferred emulator today and we don't need two different ones. 579 580 The old sibyte / swarm / Broadcom BCM1250 support has been 581 removed from the mips port. 582 58320181211: 584 Clang, llvm, lld, lldb, compiler-rt and libc++ have been upgraded to 585 7.0.1. Please see the 20141231 entry below for information about 586 prerequisites and upgrading, if you are not already using clang 3.5.0 587 or higher. 588 58920181211: 590 Remove the timed and netdate programs from the base tree. Setting 591 the time with these daemons has been obsolete for over a decade. 592 59320181126: 594 On amd64, arm64 and armv7 (architectures that install LLVM's ld.lld 595 linker as /usr/bin/ld) GNU ld is no longer installed as ld.bfd, as 596 it produces broken binaries when ifuncs are in use. Users needing 597 GNU ld should install the binutils port or package. 598 59920181123: 600 The BSD crtbegin and crtend code has been enabled by default. It has 601 had extensive testing on amd64, arm64, and i386. It can be disabled 602 by building a world with -DWITHOUT_BSD_CRTBEGIN. 603 60420181115: 605 The set of CTM commands (ctm, ctm_smail, ctm_rmail, ctm_dequeue) 606 has been converted to a port (misc/ctm) and will be removed from 607 FreeBSD-13. It is available as a package (ctm) for all supported 608 FreeBSD versions. 609 61020181110: 611 The default newsyslog.conf(5) file has been changed to only include 612 files in /etc/newsyslog.conf.d/ and /usr/local/etc/newsyslog.conf.d/ if 613 the filenames end in '.conf' and do not begin with a '.'. 614 615 You should check the configuration files in these two directories match 616 this naming convention. You can verify which configuration files are 617 being included using the command: 618 $ newsyslog -Nrv 619 62020181015: 621 Ports for the DRM modules have been simplified. Now, amd64 users should 622 just install the drm-kmod port. All others should install 623 drm-legacy-kmod. 624 625 Graphics hardware that's newer than about 2010 usually works with 626 drm-kmod. For hardware older than 2013, however, some users will need 627 to use drm-legacy-kmod if drm-kmod doesn't work for them. Hardware older 628 than 2008 usually only works in drm-legacy-kmod. The graphics team can 629 only commit to hardware made since 2013 due to the complexity of the 630 market and difficulty to test all the older cards effectively. If you 631 have hardware supported by drm-kmod, you are strongly encouraged to use 632 that as you will get better support. 633 634 Other than KPI chasing, drm-legacy-kmod will not be updated. As outlined 635 elsewhere, the drm and drm2 modules will be eliminated from the src base 636 soon (with a limited exception for arm). Please update to the package 637 asap and report any issues to x11@freebsd.org. 638 639 Generally, anybody using the drm*-kmod packages should add 640 WITHOUT_DRM_MODULE=t and WITHOUT_DRM2_MODULE=t to avoid nasty 641 cross-threading surprises, especially with automatic driver 642 loading from X11 startup. These will become the defaults in 13-current 643 shortly. 644 64520181012: 646 The ixlv(4) driver has been renamed to iavf(4). As a consequence, 647 custom kernel and module loading configuration files must be updated 648 accordingly. Moreover, interfaces previous presented as ixlvN to the 649 system are now exposed as iavfN and network configuration files must 650 be adjusted as necessary. 651 65220181009: 653 OpenSSL has been updated to version 1.1.1. This update included 654 additional various API changes throughout the base system. It is 655 important to rebuild third-party software after upgrading. The value 656 of __FreeBSD_version has been bumped accordingly. 657 65820181006: 659 The legacy DRM modules and drivers have now been added to the loader's 660 module blacklist, in favor of loading them with kld_list in rc.conf(5). 661 The module blacklist may be overridden with the loader.conf(5) 662 'module_blacklist' variable, but loading them via rc.conf(5) is strongly 663 encouraged. 664 66520181002: 666 The cam(4) based nda(4) driver will be used over nvd(4) by default on 667 powerpc64. You may set 'options NVME_USE_NVD=1' in your kernel conf or 668 loader tunable 'hw.nvme.use_nvd=1' if you wish to use the existing 669 driver. Make sure to edit /boot/etc/kboot.conf and fstab to use the 670 nda device name. 671 67220180913: 673 Reproducible build mode is now on by default, in preparation for 674 FreeBSD 12.0. This eliminates build metadata such as the user, 675 host, and time from the kernel (and uname), unless the working tree 676 corresponds to a modified checkout from a version control system. 677 The previous behavior can be obtained by setting the /etc/src.conf 678 knob WITHOUT_REPRODUCIBLE_BUILD. 679 68020180826: 681 The Yarrow CSPRNG has been removed from the kernel as it has not been 682 supported by its designers since at least 2003. Fortuna has been the 683 default since FreeBSD-11. 684 68520180822: 686 devctl freeze/thaw have gone into the tree, the rc scripts have been 687 updated to use them and devmatch has been changed. You should update 688 kernel, userland and rc scripts all at the same time. 689 69020180818: 691 The default interpreter has been switched from 4th to Lua. 692 LOADER_DEFAULT_INTERP, documented in build(7), will override the default 693 interpreter. If you have custom FORTH code you will need to set 694 LOADER_DEFAULT_INTERP=4th (valid values are 4th, lua or simp) in 695 src.conf for the build. This will create default hard links between 696 loader and loader_4th instead of loader and loader_lua, the new default. 697 If you are using UEFI it will create the proper hard link to loader.efi. 698 699 bhyve uses userboot.so. It remains 4th-only until some issues are solved 700 regarding coexisting with multiple versions of FreeBSD are resolved. 701 70220180815: 703 ls(1) now respects the COLORTERM environment variable used in other 704 systems and software to indicate that a colored terminal is both 705 supported and desired. If ls(1) is suddenly emitting colors, they may 706 be disabled again by either removing the unwanted COLORTERM from your 707 environment, or using `ls --color=never`. The ls(1) specific CLICOLOR 708 may not be observed in a future release. 709 71020180808: 711 The default pager for most commands has been changed to "less". To 712 restore the old behavior, set PAGER="more" and MANPAGER="more -s" in 713 your environment. 714 71520180731: 716 The jedec_ts(4) driver has been removed. A superset of its functionality 717 is available in the jedec_dimm(4) driver, and the manpage for that 718 driver includes migration instructions. If you have "device jedec_ts" 719 in your kernel configuration file, it must be removed. 720 72120180730: 722 amd64/GENERIC now has EFI runtime services, EFIRT, enabled by default. 723 This should have no effect if the kernel is booted via BIOS/legacy boot. 724 EFIRT may be disabled via a loader tunable, efi.rt.disabled, if a system 725 has a buggy firmware that prevents a successful boot due to use of 726 runtime services. 727 72820180727: 729 Atmel AT91RM9200 and AT91SAM9, Cavium CNS 11xx and XScale 730 support has been removed from the tree. These ports were 731 obsolete and/or known to be broken for many years. 732 73320180723: 734 loader.efi has been augmented to participate more fully in the 735 UEFI boot manager protocol. loader.efi will now look at the 736 BootXXXX environment variable to determine if a specific kernel 737 or root partition was specified. XXXX is derived from BootCurrent. 738 efibootmgr(8) manages these standard UEFI variables. 739 74020180720: 741 zfsloader's functionality has now been folded into loader. 742 zfsloader is no longer necessary once you've updated your 743 boot blocks. For a transition period, we will install a 744 hardlink for zfsloader to loader to allow a smooth transition 745 until the boot blocks can be updated (hard link because old 746 zfs boot blocks don't understand symlinks). 747 74820180719: 749 ARM64 now have efifb support, if you want to have serial console 750 on your arm64 board when an screen is connected and the bootloader 751 setup a frame buffer for us to use, just add : 752 boot_serial=YES 753 boot_multicons=YES 754 in /boot/loader.conf 755 For Raspberry Pi 3 (RPI) users, this is needed even if you don't have 756 an screen connected as the firmware will setup a frame buffer are that 757 u-boot will expose as an EFI frame buffer. 758 75920180719: 760 New uid:gid added, ntpd:ntpd (123:123). Be sure to run mergemaster 761 or take steps to update /etc/passwd before doing installworld on 762 existing systems. Do not skip the "mergemaster -Fp" step before 763 installworld, as described in the update procedures near the bottom 764 of this document. Also, rc.d/ntpd now starts ntpd(8) as user ntpd 765 if the new mac_ntpd(4) policy is available, unless ntpd_flags or 766 the ntp config file contain options that change file/dir locations. 767 When such options (e.g., "statsdir" or "crypto") are used, ntpd can 768 still be run as non-root by setting ntpd_user=ntpd in rc.conf, after 769 taking steps to ensure that all required files/dirs are accessible 770 by the ntpd user. 771 77220180717: 773 Big endian arm support has been removed. 774 77520180711: 776 The static environment setup in kernel configs is no longer mutually 777 exclusive with the loader(8) environment by default. In order to 778 restore the previous default behavior of disabling the loader(8) 779 environment if a static environment is present, you must specify 780 loader_env.disabled=1 in the static environment. 781 78220180705: 783 The ABI of syscalls used by management tools like sockstat and 784 netstat has been broken to allow 32-bit binaries to work on 785 64-bit kernels without modification. These programs will need 786 to match the kernel in order to function. External programs may 787 require minor modifications to accommodate a change of type in 788 structures from pointers to 64-bit virtual addresses. 789 79020180702: 791 On i386 and amd64 atomics are now inlined. Out of tree modules using 792 atomics will need to be rebuilt. 793 79420180701: 795 The '%I' format in the kern.corefile sysctl limits the number of 796 core files that a process can generate to the number stored in the 797 debug.ncores sysctl. The '%I' format is replaced by the single digit 798 index. Previously, if all indexes were taken the kernel would overwrite 799 only a core file with the highest index in a filename. 800 Currently the system will create a new core file if there is a free 801 index or if all slots are taken it will overwrite the oldest one. 802 80320180630: 804 Clang, llvm, lld, lldb, compiler-rt and libc++ have been upgraded to 805 6.0.1. Please see the 20141231 entry below for information about 806 prerequisites and upgrading, if you are not already using clang 3.5.0 807 or higher. 808 80920180628: 810 r335753 introduced a new quoting method. However, etc/devd/devmatch.conf 811 needed to be changed to work with it. This change was made with r335763 812 and requires a mergemaster / etcupdate / etc to update the installed 813 file. 814 81520180612: 816 r334930 changed the interface between the NFS modules, so they all 817 need to be rebuilt. r335018 did a __FreeBSD_version bump for this. 818 81920180530: 820 As of r334391 lld is the default amd64 system linker; it is installed 821 as /usr/bin/ld. Kernel build workarounds (see 20180510 entry) are no 822 longer necessary. 823 82420180530: 825 The kernel / userland interface for devinfo changed, so you'll 826 need a new kernel and userland as a pair for it to work (rebuilding 827 lib/libdevinfo is all that's required). devinfo and devmatch will 828 not work, but everything else will when there's a mismatch. 829 83020180523: 831 The on-disk format for hwpmc callchain records has changed to include 832 threadid corresponding to a given record. This changes the field offsets 833 and thus requires that libpmcstat be rebuilt before using a kernel 834 later than r334108. 835 83620180517: 837 The vxge(4) driver has been removed. This driver was introduced into 838 HEAD one week before the Exar left the Ethernet market and is not 839 known to be used. If you have device vxge in your kernel config file 840 it must be removed. 841 84220180510: 843 The amd64 kernel now requires a ld that supports ifunc to produce a 844 working kernel, either lld or a newer binutils. lld is built by default 845 on amd64, and the 'buildkernel' target uses it automatically. However, 846 it is not the default linker, so building the kernel the traditional 847 way requires LD=ld.lld on the command line (or LD=/usr/local/bin/ld for 848 binutils port/package). lld will soon be default, and this requirement 849 will go away. 850 851 NOTE: As of r334391 lld is the default system linker on amd64, and no 852 workaround is necessary. 853 85420180508: 855 The nxge(4) driver has been removed. This driver was for PCI-X 10g 856 cards made by s2io/Neterion. The company was acquired by Exar and 857 no longer sells or supports Ethernet products. If you have device 858 nxge in your kernel config file it must be removed. 859 86020180504: 861 The tz database (tzdb) has been updated to 2018e. This version more 862 correctly models time stamps in time zones with negative DST such as 863 Europe/Dublin (from 1971 on), Europe/Prague (1946/7), and 864 Africa/Windhoek (1994/2017). This does not affect the UT offsets, only 865 time zone abbreviations and the tm_isdst flag. 866 86720180502: 868 The ixgb(4) driver has been removed. This driver was for an early and 869 uncommon legacy PCI 10GbE for a single ASIC, Intel 82597EX. Intel 870 quickly shifted to the long lived ixgbe family. If you have device 871 ixgb in your kernel config file it must be removed. 872 87320180501: 874 The lmc(4) driver has been removed. This was a WAN interface 875 card that was already reportedly rare in 2003, and had an ambiguous 876 license. If you have device lmc in your kernel config file it must 877 be removed. 878 87920180413: 880 Support for Arcnet networks has been removed. If you have device 881 arcnet or device cm in your kernel config file they must be 882 removed. 883 88420180411: 885 Support for FDDI networks has been removed. If you have device 886 fddi or device fpa in your kernel config file they must be 887 removed. 888 88920180406: 890 In addition to supporting RFC 3164 formatted messages, the 891 syslogd(8) service is now capable of parsing RFC 5424 formatted 892 log messages. The main benefit of using RFC 5424 is that clients 893 may now send log messages with timestamps containing year numbers, 894 microseconds and time zone offsets. 895 896 Similarly, the syslog(3) C library function has been altered to 897 send RFC 5424 formatted messages to the local system logging 898 daemon. On systems using syslogd(8), this change should have no 899 negative impact, as long as syslogd(8) and the C library are 900 updated at the same time. On systems using a different system 901 logging daemon, it may be necessary to make configuration 902 adjustments, depending on the software used. 903 904 When using syslog-ng, add the 'syslog-protocol' flag to local 905 input sources to enable parsing of RFC 5424 formatted messages: 906 907 source src { 908 unix-dgram("/var/run/log" flags(syslog-protocol)); 909 } 910 911 When using rsyslog, disable the 'SysSock.UseSpecialParser' option 912 of the 'imuxsock' module to let messages be processed by the 913 regular RFC 3164/5424 parsing pipeline: 914 915 module(load="imuxsock" SysSock.UseSpecialParser="off") 916 917 Do note that these changes only affect communication between local 918 applications and syslogd(8). The format that syslogd(8) uses to 919 store messages on disk or forward messages to other systems 920 remains unchanged. syslogd(8) still uses RFC 3164 for these 921 purposes. Options to customize this behaviour will be added in the 922 future. Utilities that process log files stored in /var/log are 923 thus expected to continue to function as before. 924 925 __FreeBSD_version has been incremented to 1200061 to denote this 926 change. 927 92820180328: 929 Support for token ring networks has been removed. If you 930 have "device token" in your kernel config you should remove 931 it. No device drivers supported token ring. 932 93320180323: 934 makefs was modified to be able to tag ISO9660 El Torito boot catalog 935 entries as EFI instead of overloading the i386 tag as done previously. 936 The amd64 mkisoimages.sh script used to build amd64 ISO images for 937 release was updated to use this. This may mean that makefs must be 938 updated before "make cdrom" can be run in the release directory. This 939 should be as simple as: 940 941 $ cd $SRCDIR/usr.sbin/makefs 942 $ make depend all install 943 94420180212: 945 FreeBSD boot loader enhanced with Lua scripting. It's purely opt-in for 946 now by building WITH_LOADER_LUA and WITHOUT_FORTH in /etc/src.conf. 947 Co-existence for the transition period will come shortly. Booting is a 948 complex environment and test coverage for Lua-enabled loaders has been 949 thin, so it would be prudent to assume it might not work and make 950 provisions for backup boot methods. 951 95220180211: 953 devmatch functionality has been turned on in devd. It will automatically 954 load drivers for unattached devices. This may cause unexpected drivers 955 to be loaded. Please report any problems to current@ and 956 imp@freebsd.org. 957 95820180114: 959 Clang, llvm, lld, lldb, compiler-rt and libc++ have been upgraded to 960 6.0.0. Please see the 20141231 entry below for information about 961 prerequisites and upgrading, if you are not already using clang 3.5.0 962 or higher. 963 96420180110: 965 LLVM's lld linker is now used as the FreeBSD/amd64 bootstrap linker. 966 This means it is used to link the kernel and userland libraries and 967 executables, but is not yet installed as /usr/bin/ld by default. 968 969 To revert to ld.bfd as the bootstrap linker, in /etc/src.conf set 970 WITHOUT_LLD_BOOTSTRAP=yes 971 97220180110: 973 On i386, pmtimer has been removed. Its functionality has been folded 974 into apm. It was a no-op on ACPI in current for a while now (but was 975 still needed on i386 in FreeBSD 11 and earlier). Users may need to 976 remove it from kernel config files. 977 97820180104: 979 The use of RSS hash from the network card aka flowid has been 980 disabled by default for lagg(4) as it's currently incompatible with 981 the lacp and loadbalance protocols. 982 983 This can be re-enabled by setting the following in loader.conf: 984 net.link.lagg.default_use_flowid="1" 985 98620180102: 987 The SW_WATCHDOG option is no longer necessary to enable the 988 hardclock-based software watchdog if no hardware watchdog is 989 configured. As before, SW_WATCHDOG will cause the software 990 watchdog to be enabled even if a hardware watchdog is configured. 991 99220171215: 993 r326887 fixes the issue described in the 20171214 UPDATING entry. 994 r326888 flips the switch back to building GELI support always. 995 99620171214: 997 r362593 broke ZFS + GELI support for reasons unknown. However, 998 it also broke ZFS support generally, so GELI has been turned off 999 by default as the lesser evil in r326857. If you boot off ZFS and/or 1000 GELI, it might not be a good time to update. 1001 100220171125: 1003 PowerPC users must update loader(8) by rebuilding world before 1004 installing a new kernel, as the protocol connecting them has 1005 changed. Without the update, loader metadata will not be passed 1006 successfully to the kernel and users will have to enter their 1007 root partition at the kernel mountroot prompt to continue booting. 1008 Newer versions of loader can boot old kernels without issue. 1009 101020171110: 1011 The LOADER_FIREWIRE_SUPPORT build variable as been renamed to 1012 WITH/OUT_LOADER_FIREWIRE. LOADER_{NO_,}GELI_SUPPORT has been renamed 1013 to WITH/OUT_LOADER_GELI. 1014 101520171106: 1016 The naive and non-compliant support of posix_fallocate(2) in ZFS 1017 has been removed as of r325320. The system call now returns EINVAL 1018 when used on a ZFS file. Although the new behavior complies with the 1019 standard, some consumers are not prepared to cope with it. 1020 One known victim is lld prior to r325420. 1021 102220171102: 1023 Building in a FreeBSD src checkout will automatically create object 1024 directories now rather than store files in the current directory if 1025 'make obj' was not ran. Calling 'make obj' is no longer necessary. 1026 This feature can be disabled by setting WITHOUT_AUTO_OBJ=yes in 1027 /etc/src-env.conf (not /etc/src.conf), or passing the option in the 1028 environment. 1029 103020171101: 1031 The default MAKEOBJDIR has changed from /usr/obj/<srcdir> for native 1032 builds, and /usr/obj/<arch>/<srcdir> for cross-builds, to a unified 1033 /usr/obj/<srcdir>/<arch>. This behavior can be changed to the old 1034 format by setting WITHOUT_UNIFIED_OBJDIR=yes in /etc/src-env.conf, 1035 the environment, or with -DWITHOUT_UNIFIED_OBJDIR when building. 1036 The UNIFIED_OBJDIR option is a transitional feature that will be 1037 removed for 12.0 release; please migrate to the new format for any 1038 tools by looking up the OBJDIR used by 'make -V .OBJDIR' means rather 1039 than hardcoding paths. 1040 104120171028: 1042 The native-xtools target no longer installs the files by default to the 1043 OBJDIR. Use the native-xtools-install target with a DESTDIR to install 1044 to ${DESTDIR}/${NXTP} where NXTP defaults to /nxb-bin. 1045 104620171021: 1047 As part of the boot loader infrastructure cleanup, LOADER_*_SUPPORT 1048 options are changing from controlling the build if defined / undefined 1049 to controlling the build with explicit 'yes' or 'no' values. They will 1050 shift to WITH/WITHOUT options to match other options in the system. 1051 105220171010: 1053 libstand has turned into a private library for sys/boot use only. 1054 It is no longer supported as a public interface outside of sys/boot. 1055 105620171005: 1057 The arm port has split armv6 into armv6 and armv7. armv7 is now 1058 a valid TARGET_ARCH/MACHINE_ARCH setting. If you have an armv7 system 1059 and are running a kernel from before r324363, you will need to add 1060 MACHINE_ARCH=armv7 to 'make buildworld' to do a native build. 1061 106220171003: 1063 When building multiple kernels using KERNCONF, non-existent KERNCONF 1064 files will produce an error and buildkernel will fail. Previously 1065 missing KERNCONF files silently failed giving no indication as to 1066 why, only to subsequently discover during installkernel that the 1067 desired kernel was never built in the first place. 1068 106920170912: 1070 The default serial number format for CTL LUNs has changed. This will 1071 affect users who use /dev/diskid/* device nodes, or whose FibreChannel 1072 or iSCSI clients care about their LUNs' serial numbers. Users who 1073 require serial number stability should hardcode serial numbers in 1074 /etc/ctl.conf . 1075 107620170912: 1077 For 32-bit arm compiled for hard-float support, soft-floating point 1078 binaries now always get their shared libraries from 1079 LD_SOFT_LIBRARY_PATH (in the past, this was only used if 1080 /usr/libsoft also existed). Only users with a hard-float ld.so, but 1081 soft-float everything else should be affected. 1082 108320170826: 1084 The geli password typed at boot is now hidden. To restore the previous 1085 behavior, see geli(8) for configuration options. 1086 108720170825: 1088 Move PMTUD blackhole counters to TCPSTATS and remove them from bare 1089 sysctl values. Minor nit, but requires a rebuild of both world/kernel 1090 to complete. 1091 109220170814: 1093 "make check" behavior (made in ^/head@r295380) has been changed to 1094 execute from a limited sandbox, as opposed to executing from 1095 ${TESTSDIR}. 1096 1097 Behavioral changes: 1098 - The "beforecheck" and "aftercheck" targets are now specified. 1099 - ${CHECKDIR} (added in commit noted above) has been removed. 1100 - Legacy behavior can be enabled by setting 1101 WITHOUT_MAKE_CHECK_USE_SANDBOX in src.conf(5) or the environment. 1102 1103 If the limited sandbox mode is enabled, "make check" will execute 1104 "make distribution", then install, execute the tests, and clean up the 1105 sandbox if successful. 1106 1107 The "make distribution" and "make install" targets are typically run as 1108 root to set appropriate permissions and ownership at installation time. 1109 The end-user should set "WITH_INSTALL_AS_USER" in src.conf(5) or the 1110 environment if executing "make check" with limited sandbox mode using 1111 an unprivileged user. 1112 111320170808: 1114 Since the switch to GPT disk labels, fsck for UFS/FFS has been 1115 unable to automatically find alternate superblocks. As of r322297, 1116 the information needed to find alternate superblocks has been 1117 moved to the end of the area reserved for the boot block. 1118 Filesystems created with a newfs of this vintage or later 1119 will create the recovery information. If you have a filesystem 1120 created prior to this change and wish to have a recovery block 1121 created for your filesystem, you can do so by running fsck in 1122 foreground mode (i.e., do not use the -p or -y options). As it 1123 starts, fsck will ask ``SAVE DATA TO FIND ALTERNATE SUPERBLOCKS'' 1124 to which you should answer yes. 1125 112620170728: 1127 As of r321665, an NFSv4 server configuration that services 1128 Kerberos mounts or clients that do not support the uid/gid in 1129 owner/owner_group string capability, must explicitly enable 1130 the nfsuserd daemon by adding nfsuserd_enable="YES" to the 1131 machine's /etc/rc.conf file. 1132 113320170722: 1134 Clang, llvm, lldb, compiler-rt and libc++ have been upgraded to 5.0.0. 1135 Please see the 20141231 entry below for information about prerequisites 1136 and upgrading, if you are not already using clang 3.5.0 or higher. 1137 113820170701: 1139 WITHOUT_RCMDS is now the default. Set WITH_RCMDS if you need the 1140 r-commands (rlogin, rsh, etc.) to be built with the base system. 1141 114220170625: 1143 The FreeBSD/powerpc platform now uses a 64-bit type for time_t. This is 1144 a very major ABI incompatible change, so users of FreeBSD/powerpc must 1145 be careful when performing source upgrades. It is best to run 1146 'make installworld' from an alternate root system, either a live 1147 CD/memory stick, or a temporary root partition. Additionally, all ports 1148 must be recompiled. powerpc64 is largely unaffected, except in the case 1149 of 32-bit compatibility. All 32-bit binaries will be affected. 1150 115120170623: 1152 Forward compatibility for the "ino64" project have been committed. This 1153 will allow most new binaries to run on older kernels in a limited 1154 fashion. This prevents many of the common foot-shooting actions in the 1155 upgrade as well as the limited ability to roll back the kernel across 1156 the ino64 upgrade. Complicated use cases may not work properly, though 1157 enough simpler ones work to allow recovery in most situations. 1158 115920170620: 1160 Switch back to the BSDL dtc (Device Tree Compiler). Set WITH_GPL_DTC 1161 if you require the GPL compiler. 1162 116320170618: 1164 The internal ABI used for communication between the NFS kernel modules 1165 was changed by r320085, so __FreeBSD_version was bumped to 1166 ensure all the NFS related modules are updated together. 1167 116820170617: 1169 The ABI of struct event was changed by extending the data 1170 member to 64bit and adding ext fields. For upgrade, same 1171 precautions as for the entry 20170523 "ino64" must be 1172 followed. 1173 117420170531: 1175 The GNU roff toolchain has been removed from base. To render manpages 1176 which are not supported by mandoc(1), man(1) can fallback on GNU roff 1177 from ports (and recommends to install it). 1178 To render roff(7) documents, consider using GNU roff from ports or the 1179 heirloom doctools roff toolchain from ports via pkg install groff or 1180 via pkg install heirloom-doctools. 1181 118220170524: 1183 The ath(4) and ath_hal(4) modules now build piecemeal to allow for 1184 smaller runtime footprint builds. This is useful for embedded systems 1185 which only require one chipset support. 1186 1187 If you load it as a module, make sure this is in /boot/loader.conf: 1188 1189 if_ath_load="YES" 1190 1191 This will load the HAL, all chip/RF backends and if_ath_pci. 1192 If you have if_ath_pci in /boot/loader.conf, ensure it is after 1193 if_ath or it will not load any HAL chipset support. 1194 1195 If you want to selectively load things (eg on ye cheape ARM/MIPS 1196 platforms where RAM is at a premium) you should: 1197 1198 * load ath_hal 1199 * load the chip modules in question 1200 * load ath_rate, ath_dfs 1201 * load ath_main 1202 * load if_ath_pci and/or if_ath_ahb depending upon your particular 1203 bus bind type - this is where probe/attach is done. 1204 1205 For further comments/feedback, poke adrian@ . 1206 120720170523: 1208 The "ino64" 64-bit inode project has been committed, which extends 1209 a number of types to 64 bits. Upgrading in place requires care and 1210 adherence to the documented upgrade procedure. 1211 1212 If using a custom kernel configuration ensure that the 1213 COMPAT_FREEBSD11 option is included (as during the upgrade the 1214 system will be running the ino64 kernel with the existing world). 1215 1216 For the safest in-place upgrade begin by removing previous build 1217 artifacts via "rm -rf /usr/obj/*". Then, carefully follow the full 1218 procedure documented below under the heading "To rebuild everything and 1219 install it on the current system." Specifically, a reboot is required 1220 after installing the new kernel before installing world. While an 1221 installworld normally works by accident from multiuser after rebooting 1222 the proper kernel, there are many cases where this will fail across this 1223 upgrade and installworld from single user is required. 1224 122520170424: 1226 The NATM framework including the en(4), fatm(4), hatm(4), and 1227 patm(4) devices has been removed. Consumers should plan a 1228 migration before the end-of-life date for FreeBSD 11. 1229 123020170420: 1231 GNU diff has been replaced by a BSD licensed diff. Some features of GNU 1232 diff has not been implemented, if those are needed a newer version of 1233 GNU diff is available via the diffutils package under the gdiff name. 1234 123520170413: 1236 As of r316810 for ipfilter, keep frags is no longer assumed when 1237 keep state is specified in a rule. r316810 aligns ipfilter with 1238 documentation in man pages separating keep frags from keep state. 1239 This allows keep state to be specified without forcing keep frags 1240 and allows keep frags to be specified independently of keep state. 1241 To maintain previous behaviour, also specify keep frags with 1242 keep state (as documented in ipf.conf.5). 1243 124420170407: 1245 arm64 builds now use the base system LLD 4.0.0 linker by default, 1246 instead of requiring that the aarch64-binutils port or package be 1247 installed. To continue using aarch64-binutils, set 1248 CROSS_BINUTILS_PREFIX=/usr/local/aarch64-freebsd/bin . 1249 125020170405: 1251 The UDP optimization in entry 20160818 that added the sysctl 1252 net.inet.udp.require_l2_bcast has been reverted. L2 broadcast 1253 packets will no longer be treated as L3 broadcast packets. 1254 125520170331: 1256 Binds and sends to the loopback addresses, IPv6 and IPv4, will now 1257 use any explicitly assigned loopback address available in the jail 1258 instead of using the first assigned address of the jail. 1259 126020170329: 1261 The ctl.ko module no longer implements the iSCSI target frontend: 1262 cfiscsi.ko does instead. 1263 1264 If building cfiscsi.ko as a kernel module, the module can be loaded 1265 via one of the following methods: 1266 - `cfiscsi_load="YES"` in loader.conf(5). 1267 - Add `cfiscsi` to `$kld_list` in rc.conf(5). 1268 - ctladm(8)/ctld(8), when compiled with iSCSI support 1269 (`WITH_ISCSI=yes` in src.conf(5)) 1270 1271 Please see cfiscsi(4) for more details. 1272 127320170316: 1274 The mmcsd.ko module now additionally depends on geom_flashmap.ko. 1275 Also, mmc.ko and mmcsd.ko need to be a matching pair built from the 1276 same source (previously, the dependency of mmcsd.ko on mmc.ko was 1277 missing, but mmcsd.ko now will refuse to load if it is incompatible 1278 with mmc.ko). 1279 128020170315: 1281 The syntax of ipfw(8) named states was changed to avoid ambiguity. 1282 If you have used named states in the firewall rules, you need to modify 1283 them after installworld and before rebooting. Now named states must 1284 be prefixed with colon. 1285 128620170311: 1287 The old drm (sys/dev/drm/) drivers for i915 and radeon have been 1288 removed as the userland we provide cannot use them. The KMS version 1289 (sys/dev/drm2) supports the same hardware. 1290 129120170302: 1292 Clang, llvm, lldb, compiler-rt and libc++ have been upgraded to 4.0.0. 1293 Please see the 20141231 entry below for information about prerequisites 1294 and upgrading, if you are not already using clang 3.5.0 or higher. 1295 129620170221: 1297 The code that provides support for ZFS .zfs/ directory functionality 1298 has been reimplemented. It's not possible now to create a snapshot 1299 by mkdir under .zfs/snapshot/. That should be the only user visible 1300 change. 1301 130220170216: 1303 EISA bus support has been removed. The WITH_EISA option is no longer 1304 valid. 1305 130620170215: 1307 MCA bus support has been removed. 1308 130920170127: 1310 The WITH_LLD_AS_LD / WITHOUT_LLD_AS_LD build knobs have been renamed 1311 WITH_LLD_IS_LD / WITHOUT_LLD_IS_LD, for consistency with CLANG_IS_CC. 1312 131320170112: 1314 The EM_MULTIQUEUE kernel configuration option is deprecated now that 1315 the em(4) driver conforms to iflib specifications. 1316 131720170109: 1318 The igb(4), em(4) and lem(4) ethernet drivers are now implemented via 1319 IFLIB. If you have a custom kernel configuration that excludes em(4) 1320 but you use igb(4), you need to re-add em(4) to your custom 1321 configuration. 1322 132320161217: 1324 Clang, llvm, lldb, compiler-rt and libc++ have been upgraded to 3.9.1. 1325 Please see the 20141231 entry below for information about prerequisites 1326 and upgrading, if you are not already using clang 3.5.0 or higher. 1327 132820161124: 1329 Clang, llvm, lldb, compiler-rt and libc++ have been upgraded to 3.9.0. 1330 Please see the 20141231 entry below for information about prerequisites 1331 and upgrading, if you are not already using clang 3.5.0 or higher. 1332 133320161119: 1334 The layout of the pmap structure has changed for powerpc to put the pmap 1335 statistics at the front for all CPU variations. libkvm(3) and all tools 1336 that link against it need to be recompiled. 1337 133820161030: 1339 isl(4) and cyapa(4) drivers now require a new driver, 1340 chromebook_platform(4), to work properly on Chromebook-class hardware. 1341 On other types of hardware the drivers may need to be configured using 1342 device hints. Please see the corresponding manual pages for details. 1343 134420161017: 1345 The urtwn(4) driver was merged into rtwn(4) and now consists of 1346 rtwn(4) main module + rtwn_usb(4) and rtwn_pci(4) bus-specific 1347 parts. 1348 Also, firmware for RTL8188CE was renamed due to possible name 1349 conflict (rtwnrtl8192cU(B) -> rtwnrtl8192cE(B)) 1350 135120161015: 1352 GNU rcs has been removed from base. It is available as packages: 1353 - rcs: Latest GPLv3 GNU rcs version. 1354 - rcs57: Copy of the latest version of GNU rcs (GPLv2) before it was 1355 removed from base. 1356 135720161008: 1358 Use of the cc_cdg, cc_chd, cc_hd, or cc_vegas congestion control 1359 modules now requires that the kernel configuration contain the 1360 TCP_HHOOK option. (This option is included in the GENERIC kernel.) 1361 136220161003: 1363 The WITHOUT_ELFCOPY_AS_OBJCOPY src.conf(5) knob has been retired. 1364 ELF Tool Chain's elfcopy is always installed as /usr/bin/objcopy. 1365 136620160924: 1367 Relocatable object files with the extension of .So have been renamed 1368 to use an extension of .pico instead. The purpose of this change is 1369 to avoid a name clash with shared libraries on case-insensitive file 1370 systems. On those file systems, foo.So is the same file as foo.so. 1371 137220160918: 1373 GNU rcs has been turned off by default. It can (temporarily) be built 1374 again by adding WITH_RCS knob in src.conf. 1375 Otherwise, GNU rcs is available from packages: 1376 - rcs: Latest GPLv3 GNU rcs version. 1377 - rcs57: Copy of the latest version of GNU rcs (GPLv2) from base. 1378 137920160918: 1380 The backup_uses_rcs functionality has been removed from rc.subr. 1381 138220160908: 1383 The queue(3) debugging macro, QUEUE_MACRO_DEBUG, has been split into 1384 two separate components, QUEUE_MACRO_DEBUG_TRACE and 1385 QUEUE_MACRO_DEBUG_TRASH. Define both for the original 1386 QUEUE_MACRO_DEBUG behavior. 1387 138820160824: 1389 r304787 changed some ioctl interfaces between the iSCSI userspace 1390 programs and the kernel. ctladm, ctld, iscsictl, and iscsid must be 1391 rebuilt to work with new kernels. __FreeBSD_version has been bumped 1392 to 1200005. 1393 139420160818: 1395 The UDP receive code has been updated to only treat incoming UDP 1396 packets that were addressed to an L2 broadcast address as L3 1397 broadcast packets. It is not expected that this will affect any 1398 standards-conforming UDP application. The new behaviour can be 1399 disabled by setting the sysctl net.inet.udp.require_l2_bcast to 1400 0. 1401 140220160818: 1403 Remove the openbsd_poll system call. 1404 __FreeBSD_version has been bumped because of this. 1405 140620160708: 1407 The stable/11 branch has been created from head@r302406. 1408 140920160622: 1410 The libc stub for the pipe(2) system call has been replaced with 1411 a wrapper that calls the pipe2(2) system call and the pipe(2) 1412 system call is now only implemented by the kernels that include 1413 "options COMPAT_FREEBSD10" in their config file (this is the 1414 default). Users should ensure that this option is enabled in 1415 their kernel or upgrade userspace to r302092 before upgrading their 1416 kernel. 1417 141820160527: 1419 CAM will now strip leading spaces from SCSI disks' serial numbers. 1420 This will affect users who create UFS filesystems on SCSI disks using 1421 those disk's diskid device nodes. For example, if /etc/fstab 1422 previously contained a line like 1423 "/dev/diskid/DISK-%20%20%20%20%20%20%20ABCDEFG0123456", you should 1424 change it to "/dev/diskid/DISK-ABCDEFG0123456". Users of geom 1425 transforms like gmirror may also be affected. ZFS users should 1426 generally be fine. 1427 142820160523: 1429 The bitstring(3) API has been updated with new functionality and 1430 improved performance. But it is binary-incompatible with the old API. 1431 Objects built with the new headers may not be linked against objects 1432 built with the old headers. 1433 143420160520: 1435 The brk and sbrk functions have been removed from libc on arm64. 1436 Binutils from ports has been updated to not link to these 1437 functions and should be updated to the latest version before 1438 installing a new libc. 1439 144020160517: 1441 The armv6 port now defaults to hard float ABI. Limited support 1442 for running both hardfloat and soft float on the same system 1443 is available using the libraries installed with -DWITH_LIBSOFT. 1444 This has only been tested as an upgrade path for installworld 1445 and packages may fail or need manual intervention to run. New 1446 packages will be needed. 1447 1448 To update an existing self-hosted armv6hf system, you must add 1449 TARGET_ARCH=armv6 on the make command line for both the build 1450 and the install steps. 1451 145220160510: 1453 Kernel modules compiled outside of a kernel build now default to 1454 installing to /boot/modules instead of /boot/kernel. Many kernel 1455 modules built this way (such as those in ports) already overrode 1456 KMODDIR explicitly to install into /boot/modules. However, 1457 manually building and installing a module from /sys/modules will 1458 now install to /boot/modules instead of /boot/kernel. 1459 146020160414: 1461 The CAM I/O scheduler has been committed to the kernel. There should be 1462 no user visible impact. This does enable NCQ Trim on ada SSDs. While the 1463 list of known rogues that claim support for this but actually corrupt 1464 data is believed to be complete, be on the lookout for data 1465 corruption. The known rogue list is believed to be complete: 1466 1467 o Crucial MX100, M550 drives with MU01 firmware. 1468 o Micron M510 and M550 drives with MU01 firmware. 1469 o Micron M500 prior to MU07 firmware 1470 o Samsung 830, 840, and 850 all firmwares 1471 o FCCT M500 all firmwares 1472 1473 Crucial has firmware http://www.crucial.com/usa/en/support-ssd-firmware 1474 with working NCQ TRIM. For Micron branded drives, see your sales rep for 1475 updated firmware. Black listed drives will work correctly because these 1476 drives work correctly so long as no NCQ TRIMs are sent to them. Given 1477 this list is the same as found in Linux, it's believed there are no 1478 other rogues in the market place. All other models from the above 1479 vendors work. 1480 1481 To be safe, if you are at all concerned, you can quirk each of your 1482 drives to prevent NCQ from being sent by setting: 1483 kern.cam.ada.X.quirks="0x2" 1484 in loader.conf. If the drive requires the 4k sector quirk, set the 1485 quirks entry to 0x3. 1486 148720160330: 1488 The FAST_DEPEND build option has been removed and its functionality is 1489 now the one true way. The old mkdep(1) style of 'make depend' has 1490 been removed. See 20160311 for further details. 1491 149220160317: 1493 Resource range types have grown from unsigned long to uintmax_t. All 1494 drivers, and anything using libdevinfo, need to be recompiled. 1495 149620160311: 1497 WITH_FAST_DEPEND is now enabled by default for in-tree and out-of-tree 1498 builds. It no longer runs mkdep(1) during 'make depend', and the 1499 'make depend' stage can safely be skipped now as it is auto ran 1500 when building 'make all' and will generate all SRCS and DPSRCS before 1501 building anything else. Dependencies are gathered at compile time with 1502 -MF flags kept in separate .depend files per object file. Users should 1503 run 'make cleandepend' once if using -DNO_CLEAN to clean out older 1504 stale .depend files. 1505 150620160306: 1507 On amd64, clang 3.8.0 can now insert sections of type AMD64_UNWIND into 1508 kernel modules. Therefore, if you load any kernel modules at boot time, 1509 please install the boot loaders after you install the kernel, but before 1510 rebooting, e.g.: 1511 1512 make buildworld 1513 make buildkernel KERNCONF=YOUR_KERNEL_HERE 1514 make installkernel KERNCONF=YOUR_KERNEL_HERE 1515 make -C sys/boot install 1516 <reboot in single user> 1517 1518 Then follow the usual steps, described in the General Notes section, 1519 below. 1520 152120160305: 1522 Clang, llvm, lldb and compiler-rt have been upgraded to 3.8.0. Please 1523 see the 20141231 entry below for information about prerequisites and 1524 upgrading, if you are not already using clang 3.5.0 or higher. 1525 152620160301: 1527 The AIO subsystem is now a standard part of the kernel. The 1528 VFS_AIO kernel option and aio.ko kernel module have been removed. 1529 Due to stability concerns, asynchronous I/O requests are only 1530 permitted on sockets and raw disks by default. To enable 1531 asynchronous I/O requests on all file types, set the 1532 vfs.aio.enable_unsafe sysctl to a non-zero value. 1533 153420160226: 1535 The ELF object manipulation tool objcopy is now provided by the 1536 ELF Tool Chain project rather than by GNU binutils. It should be a 1537 drop-in replacement, with the addition of arm64 support. The 1538 (temporary) src.conf knob WITHOUT_ELFCOPY_AS_OBJCOPY knob may be set 1539 to obtain the GNU version if necessary. 1540 154120160129: 1542 Building ZFS pools on top of zvols is prohibited by default. That 1543 feature has never worked safely; it's always been prone to deadlocks. 1544 Using a zvol as the backing store for a VM guest's virtual disk will 1545 still work, even if the guest is using ZFS. Legacy behavior can be 1546 restored by setting vfs.zfs.vol.recursive=1. 1547 154820160119: 1549 The NONE and HPN patches has been removed from OpenSSH. They are 1550 still available in the security/openssh-portable port. 1551 155220160113: 1553 With the addition of ypldap(8), a new _ypldap user is now required 1554 during installworld. "mergemaster -p" can be used to add the user 1555 prior to installworld, as documented in the handbook. 1556 155720151216: 1558 The tftp loader (pxeboot) now uses the option root-path directive. As a 1559 consequence it no longer looks for a pxeboot.4th file on the tftp 1560 server. Instead it uses the regular /boot infrastructure as with the 1561 other loaders. 1562 156320151211: 1564 The code to start recording plug and play data into the modules has 1565 been committed. While the old tools will properly build a new kernel, 1566 a number of warnings about "unknown metadata record 4" will be produced 1567 for an older kldxref. To avoid such warnings, make sure to rebuild 1568 the kernel toolchain (or world). Make sure that you have r292078 or 1569 later when trying to build 292077 or later before rebuilding. 1570 157120151207: 1572 Debug data files are now built by default with 'make buildworld' and 1573 installed with 'make installworld'. This facilitates debugging but 1574 requires more disk space both during the build and for the installed 1575 world. Debug files may be disabled by setting WITHOUT_DEBUG_FILES=yes 1576 in src.conf(5). 1577 157820151130: 1579 r291527 changed the internal interface between the nfsd.ko and 1580 nfscommon.ko modules. As such, they must both be upgraded to-gether. 1581 __FreeBSD_version has been bumped because of this. 1582 158320151108: 1584 Add support for unicode collation strings leads to a change of 1585 order of files listed by ls(1) for example. To get back to the old 1586 behaviour, set LC_COLLATE environment variable to "C". 1587 1588 Databases administrators will need to reindex their databases given 1589 collation results will be different. 1590 1591 Due to a bug in install(1) it is recommended to remove the ancient 1592 locales before running make installworld. 1593 1594 rm -rf /usr/share/locale/* 1595 159620151030: 1597 The OpenSSL has been upgraded to 1.0.2d. Any binaries requiring 1598 libcrypto.so.7 or libssl.so.7 must be recompiled. 1599 160020151020: 1601 Qlogic 24xx/25xx firmware images were updated from 5.5.0 to 7.3.0. 1602 Kernel modules isp_2400_multi and isp_2500_multi were removed and 1603 should be replaced with isp_2400 and isp_2500 modules respectively. 1604 160520151017: 1606 The build previously allowed using 'make -n' to not recurse into 1607 sub-directories while showing what commands would be executed, and 1608 'make -n -n' to recursively show commands. Now 'make -n' will recurse 1609 and 'make -N' will not. 1610 161120151012: 1612 If you specify SENDMAIL_MC or SENDMAIL_CF in make.conf, mergemaster 1613 and etcupdate will now use this file. A custom sendmail.cf is now 1614 updated via this mechanism rather than via installworld. If you had 1615 excluded sendmail.cf in mergemaster.rc or etcupdate.conf, you may 1616 want to remove the exclusion or change it to "always install". 1617 /etc/mail/sendmail.cf is now managed the same way regardless of 1618 whether SENDMAIL_MC/SENDMAIL_CF is used. If you are not using 1619 SENDMAIL_MC/SENDMAIL_CF there should be no change in behavior. 1620 162120151011: 1622 Compatibility shims for legacy ATA device names have been removed. 1623 It includes ATA_STATIC_ID kernel option, kern.cam.ada.legacy_aliases 1624 and kern.geom.raid.legacy_aliases loader tunables, kern.devalias.* 1625 environment variables, /dev/ad* and /dev/ar* symbolic links. 1626 162720151006: 1628 Clang, llvm, lldb, compiler-rt and libc++ have been upgraded to 3.7.0. 1629 Please see the 20141231 entry below for information about prerequisites 1630 and upgrading, if you are not already using clang 3.5.0 or higher. 1631 163220150924: 1633 Kernel debug files have been moved to /usr/lib/debug/boot/kernel/, 1634 and renamed from .symbols to .debug. This reduces the size requirements 1635 on the boot partition or file system and provides consistency with 1636 userland debug files. 1637 1638 When using the supported kernel installation method the 1639 /usr/lib/debug/boot/kernel directory will be renamed (to kernel.old) 1640 as is done with /boot/kernel. 1641 1642 Developers wishing to maintain the historical behavior of installing 1643 debug files in /boot/kernel/ can set KERN_DEBUGDIR="" in src.conf(5). 1644 164520150827: 1646 The wireless drivers had undergone changes that remove the 'parent 1647 interface' from the ifconfig -l output. The rc.d network scripts 1648 used to check presence of a parent interface in the list, so old 1649 scripts would fail to start wireless networking. Thus, etcupdate(3) 1650 or mergemaster(8) run is required after kernel update, to update your 1651 rc.d scripts in /etc. 1652 165320150827: 1654 pf no longer supports 'scrub fragment crop' or 'scrub fragment drop-ovl' 1655 These configurations are now automatically interpreted as 1656 'scrub fragment reassemble'. 1657 165820150817: 1659 Kernel-loadable modules for the random(4) device are back. To use 1660 them, the kernel must have 1661 1662 device random 1663 options RANDOM_LOADABLE 1664 1665 kldload(8) can then be used to load random_fortuna.ko 1666 or random_yarrow.ko. Please note that due to the indirect 1667 function calls that the loadable modules need to provide, 1668 the build-in variants will be slightly more efficient. 1669 1670 The random(4) kernel option RANDOM_DUMMY has been retired due to 1671 unpopularity. It was not all that useful anyway. 1672 167320150813: 1674 The WITHOUT_ELFTOOLCHAIN_TOOLS src.conf(5) knob has been retired. 1675 Control over building the ELF Tool Chain tools is now provided by 1676 the WITHOUT_TOOLCHAIN knob. 1677 167820150810: 1679 The polarity of Pulse Per Second (PPS) capture events with the 1680 uart(4) driver has been corrected. Prior to this change the PPS 1681 "assert" event corresponded to the trailing edge of a positive PPS 1682 pulse and the "clear" event was the leading edge of the next pulse. 1683 1684 As the width of a PPS pulse in a typical GPS receiver is on the 1685 order of 1 millisecond, most users will not notice any significant 1686 difference with this change. 1687 1688 Anyone who has compensated for the historical polarity reversal by 1689 configuring a negative offset equal to the pulse width will need to 1690 remove that workaround. 1691 169220150809: 1693 The default group assigned to /dev/dri entries has been changed 1694 from 'wheel' to 'video' with the id of '44'. If you want to have 1695 access to the dri devices please add yourself to the video group 1696 with: 1697 1698 # pw groupmod video -m $USER 1699 170020150806: 1701 The menu.rc and loader.rc files will now be replaced during 1702 upgrades. Please migrate local changes to menu.rc.local and 1703 loader.rc.local instead. 1704 170520150805: 1706 GNU Binutils versions of addr2line, c++filt, nm, readelf, size, 1707 strings and strip have been removed. The src.conf(5) knob 1708 WITHOUT_ELFTOOLCHAIN_TOOLS no longer provides the binutils tools. 1709 171020150728: 1711 As ZFS requires more kernel stack pages than is the default on some 1712 architectures e.g. i386, it now warns if KSTACK_PAGES is less than 1713 ZFS_MIN_KSTACK_PAGES (which is 4 at the time of writing). 1714 1715 Please consider using 'options KSTACK_PAGES=X' where X is greater 1716 than or equal to ZFS_MIN_KSTACK_PAGES i.e. 4 in such configurations. 1717 171820150706: 1719 sendmail has been updated to 8.15.2. Starting with FreeBSD 11.0 1720 and sendmail 8.15, sendmail uses uncompressed IPv6 addresses by 1721 default, i.e., they will not contain "::". For example, instead 1722 of ::1, it will be 0:0:0:0:0:0:0:1. This permits a zero subnet 1723 to have a more specific match, such as different map entries for 1724 IPv6:0:0 vs IPv6:0. This change requires that configuration 1725 data (including maps, files, classes, custom ruleset, etc.) must 1726 use the same format, so make certain such configuration data is 1727 upgrading. As a very simple check search for patterns like 1728 'IPv6:[0-9a-fA-F:]*::' and 'IPv6::'. To return to the old 1729 behavior, set the m4 option confUSE_COMPRESSED_IPV6_ADDRESSES or 1730 the cf option UseCompressedIPv6Addresses. 1731 173220150630: 1733 The default kernel entropy-processing algorithm is now 1734 Fortuna, replacing Yarrow. 1735 1736 Assuming you have 'device random' in your kernel config 1737 file, the configurations allow a kernel option to override 1738 this default. You may choose *ONE* of: 1739 1740 options RANDOM_YARROW # Legacy /dev/random algorithm. 1741 options RANDOM_DUMMY # Blocking-only driver. 1742 1743 If you have neither, you get Fortuna. For most people, 1744 read no further, Fortuna will give a /dev/random that works 1745 like it always used to, and the difference will be irrelevant. 1746 1747 If you remove 'device random', you get *NO* kernel-processed 1748 entropy at all. This may be acceptable to folks building 1749 embedded systems, but has complications. Carry on reading, 1750 and it is assumed you know what you need. 1751 1752 *PLEASE* read random(4) and random(9) if you are in the 1753 habit of tweaking kernel configs, and/or if you are a member 1754 of the embedded community, wanting specific and not-usual 1755 behaviour from your security subsystems. 1756 1757 NOTE!! If you use RANDOM_DUMMY and/or have no 'device 1758 random', you will NOT have a functioning /dev/random, and 1759 many cryptographic features will not work, including SSH. 1760 You may also find strange behaviour from the random(3) set 1761 of library functions, in particular sranddev(3), srandomdev(3) 1762 and arc4random(3). The reason for this is that the KERN_ARND 1763 sysctl only returns entropy if it thinks it has some to 1764 share, and with RANDOM_DUMMY or no 'device random' this 1765 will never happen. 1766 176720150623: 1768 An additional fix for the issue described in the 20150614 sendmail 1769 entry below has been committed in revision 284717. 1770 177120150616: 1772 FreeBSD's old make (fmake) has been removed from the system. It is 1773 available as the devel/fmake port or via pkg install fmake. 1774 177520150615: 1776 The fix for the issue described in the 20150614 sendmail entry 1777 below has been committed in revision 284436. The work 1778 around described in that entry is no longer needed unless the 1779 default setting is overridden by a confDH_PARAMETERS configuration 1780 setting of '5' or pointing to a 512 bit DH parameter file. 1781 178220150614: 1783 ALLOW_DEPRECATED_ATF_TOOLS/ATFFILE support has been removed from 1784 atf.test.mk (included from bsd.test.mk). Please upgrade devel/atf 1785 and devel/kyua to version 0.20+ and adjust any calling code to work 1786 with Kyuafile and kyua. 1787 178820150614: 1789 The import of openssl to address the FreeBSD-SA-15:10.openssl 1790 security advisory includes a change which rejects handshakes 1791 with DH parameters below 768 bits. sendmail releases prior 1792 to 8.15.2 (not yet released), defaulted to a 512 bit 1793 DH parameter setting for client connections. To work around 1794 this interoperability, sendmail can be configured to use a 1795 2048 bit DH parameter by: 1796 1797 1. Edit /etc/mail/`hostname`.mc 1798 2. If a setting for confDH_PARAMETERS does not exist or 1799 exists and is set to a string beginning with '5', 1800 replace it with '2'. 1801 3. If a setting for confDH_PARAMETERS exists and is set to 1802 a file path, create a new file with: 1803 openssl dhparam -out /path/to/file 2048 1804 4. Rebuild the .cf file: 1805 cd /etc/mail/; make; make install 1806 5. Restart sendmail: 1807 cd /etc/mail/; make restart 1808 1809 A sendmail patch is coming, at which time this file will be 1810 updated. 1811 181220150604: 1813 Generation of legacy formatted entries have been disabled by default 1814 in pwd_mkdb(8), as all base system consumers of the legacy formatted 1815 entries were converted to use the new format by default when the new, 1816 machine independent format have been added and supported since FreeBSD 1817 5.x. 1818 1819 Please see the pwd_mkdb(8) manual page for further details. 1820 182120150525: 1822 Clang and llvm have been upgraded to 3.6.1 release. Please see the 1823 20141231 entry below for information about prerequisites and upgrading, 1824 if you are not already using 3.5.0 or higher. 1825 182620150521: 1827 TI platform code switched to using vendor DTS files and this update 1828 may break existing systems running on Beaglebone, Beaglebone Black, 1829 and Pandaboard: 1830 1831 - dtb files should be regenerated/reinstalled. Filenames are the 1832 same but content is different now 1833 - GPIO addressing was changed, now each GPIO bank (32 pins per bank) 1834 has its own /dev/gpiocX device, e.g. pin 121 on /dev/gpioc0 in old 1835 addressing scheme is now pin 25 on /dev/gpioc3. 1836 - Pandaboard: /etc/ttys should be updated, serial console device is 1837 now /dev/ttyu2, not /dev/ttyu0 1838 183920150501: 1840 soelim(1) from gnu/usr.bin/groff has been replaced by usr.bin/soelim. 1841 If you need the GNU extension from groff soelim(1), install groff 1842 from package: pkg install groff, or via ports: textproc/groff. 1843 184420150423: 1845 chmod, chflags, chown and chgrp now affect symlinks in -R mode as 1846 defined in symlink(7); previously symlinks were silently ignored. 1847 184820150415: 1849 The const qualifier has been removed from iconv(3) to comply with 1850 POSIX. The ports tree is aware of this from r384038 onwards. 1851 185220150416: 1853 Libraries specified by LIBADD in Makefiles must have a corresponding 1854 DPADD_<lib> variable to ensure correct dependencies. This is now 1855 enforced in src.libnames.mk. 1856 185720150324: 1858 From legacy ata(4) driver was removed support for SATA controllers 1859 supported by more functional drivers ahci(4), siis(4) and mvs(4). 1860 Kernel modules ataahci and ataadaptec were removed completely, 1861 replaced by ahci and mvs modules respectively. 1862 186320150315: 1864 Clang, llvm and lldb have been upgraded to 3.6.0 release. Please see 1865 the 20141231 entry below for information about prerequisites and 1866 upgrading, if you are not already using 3.5.0 or higher. 1867 186820150307: 1869 The 32-bit PowerPC kernel has been changed to a position-independent 1870 executable. This can only be booted with a version of loader(8) 1871 newer than January 31, 2015, so make sure to update both world and 1872 kernel before rebooting. 1873 187420150217: 1875 If you are running a -CURRENT kernel since r273872 (Oct 30th, 2014), 1876 but before r278950, the RNG was not seeded properly. Immediately 1877 upgrade the kernel to r278950 or later and regenerate any keys (e.g. 1878 ssh keys or openssl keys) that were generated w/ a kernel from that 1879 range. This does not affect programs that directly used /dev/random 1880 or /dev/urandom. All userland uses of arc4random(3) are affected. 1881 188220150210: 1883 The autofs(4) ABI was changed in order to restore binary compatibility 1884 with 10.1-RELEASE. The automountd(8) daemon needs to be rebuilt to work 1885 with the new kernel. 1886 188720150131: 1888 The powerpc64 kernel has been changed to a position-independent 1889 executable. This can only be booted with a new version of loader(8), 1890 so make sure to update both world and kernel before rebooting. 1891 189220150118: 1893 Clang and llvm have been upgraded to 3.5.1 release. This is a bugfix 1894 only release, no new features have been added. Please see the 20141231 1895 entry below for information about prerequisites and upgrading, if you 1896 are not already using 3.5.0. 1897 189820150107: 1899 ELF tools addr2line, elfcopy (strip), nm, size, and strings are now 1900 taken from the ELF Tool Chain project rather than GNU binutils. They 1901 should be drop-in replacements, with the addition of arm64 support. 1902 The WITHOUT_ELFTOOLCHAIN_TOOLS= knob may be used to obtain the 1903 binutils tools, if necessary. See 20150805 for updated information. 1904 190520150105: 1906 The default Unbound configuration now enables remote control 1907 using a local socket. Users who have already enabled the 1908 local_unbound service should regenerate their configuration 1909 by running "service local_unbound setup" as root. 1910 191120150102: 1912 The GNU texinfo and GNU info pages have been removed. 1913 To be able to view GNU info pages please install texinfo from ports. 1914 191520141231: 1916 Clang, llvm and lldb have been upgraded to 3.5.0 release. 1917 1918 As of this release, a prerequisite for building clang, llvm and lldb is 1919 a C++11 capable compiler and C++11 standard library. This means that to 1920 be able to successfully build the cross-tools stage of buildworld, with 1921 clang as the bootstrap compiler, your system compiler or cross compiler 1922 should either be clang 3.3 or later, or gcc 4.8 or later, and your 1923 system C++ library should be libc++, or libdstdc++ from gcc 4.8 or 1924 later. 1925 1926 On any standard FreeBSD 10.x or 11.x installation, where clang and 1927 libc++ are on by default (that is, on x86 or arm), this should work out 1928 of the box. 1929 1930 On 9.x installations where clang is enabled by default, e.g. on x86 and 1931 powerpc, libc++ will not be enabled by default, so libc++ should be 1932 built (with clang) and installed first. If both clang and libc++ are 1933 missing, build clang first, then use it to build libc++. 1934 1935 On 8.x and earlier installations, upgrade to 9.x first, and then follow 1936 the instructions for 9.x above. 1937 1938 Sparc64 and mips users are unaffected, as they still use gcc 4.2.1 by 1939 default, and do not build clang. 1940 1941 Many embedded systems are resource constrained, and will not be able to 1942 build clang in a reasonable time, or in some cases at all. In those 1943 cases, cross building bootable systems on amd64 is a workaround. 1944 1945 This new version of clang introduces a number of new warnings, of which 1946 the following are most likely to appear: 1947 1948 -Wabsolute-value 1949 1950 This warns in two cases, for both C and C++: 1951 * When the code is trying to take the absolute value of an unsigned 1952 quantity, which is effectively a no-op, and almost never what was 1953 intended. The code should be fixed, if at all possible. If you are 1954 sure that the unsigned quantity can be safely cast to signed, without 1955 loss of information or undefined behavior, you can add an explicit 1956 cast, or disable the warning. 1957 1958 * When the code is trying to take an absolute value, but the called 1959 abs() variant is for the wrong type, which can lead to truncation. 1960 If you want to disable the warning instead of fixing the code, please 1961 make sure that truncation will not occur, or it might lead to unwanted 1962 side-effects. 1963 1964 -Wtautological-undefined-compare and 1965 -Wundefined-bool-conversion 1966 1967 These warn when C++ code is trying to compare 'this' against NULL, while 1968 'this' should never be NULL in well-defined C++ code. However, there is 1969 some legacy (pre C++11) code out there, which actively abuses this 1970 feature, which was less strictly defined in previous C++ versions. 1971 1972 Squid and openjdk do this, for example. The warning can be turned off 1973 for C++98 and earlier, but compiling the code in C++11 mode might result 1974 in unexpected behavior; for example, the parts of the program that are 1975 unreachable could be optimized away. 1976 197720141222: 1978 The old NFS client and server (kernel options NFSCLIENT, NFSSERVER) 1979 kernel sources have been removed. The .h files remain, since some 1980 utilities include them. This will need to be fixed later. 1981 If "mount -t oldnfs ..." is attempted, it will fail. 1982 If the "-o" option on mountd(8), nfsd(8) or nfsstat(1) is used, 1983 the utilities will report errors. 1984 198520141121: 1986 The handling of LOCAL_LIB_DIRS has been altered to skip addition of 1987 directories to top level SUBDIR variable when their parent 1988 directory is included in LOCAL_DIRS. Users with build systems with 1989 such hierarchies and without SUBDIR entries in the parent 1990 directory Makefiles should add them or add the directories to 1991 LOCAL_DIRS. 1992 199320141109: 1994 faith(4) and faithd(8) have been removed from the base system. Faith 1995 has been obsolete for a very long time. 1996 199720141104: 1998 vt(4), the new console driver, is enabled by default. It brings 1999 support for Unicode and double-width characters, as well as 2000 support for UEFI and integration with the KMS kernel video 2001 drivers. 2002 2003 You may need to update your console settings in /etc/rc.conf, 2004 most probably the keymap. During boot, /etc/rc.d/syscons will 2005 indicate what you need to do. 2006 2007 vt(4) still has issues and lacks some features compared to 2008 syscons(4). See the wiki for up-to-date information: 2009 https://wiki.freebsd.org/Newcons 2010 2011 If you want to keep using syscons(4), you can do so by adding 2012 the following line to /boot/loader.conf: 2013 kern.vty=sc 2014 201520141102: 2016 pjdfstest has been integrated into kyua as an opt-in test suite. 2017 Please see share/doc/pjdfstest/README for more details on how to 2018 execute it. 2019 202020141009: 2021 gperf has been removed from the base system for architectures 2022 that use clang. Ports that require gperf will obtain it from the 2023 devel/gperf port. 2024 202520140923: 2026 pjdfstest has been moved from tools/regression/pjdfstest to 2027 contrib/pjdfstest . 2028 202920140922: 2030 At svn r271982, The default linux compat kernel ABI has been adjusted 2031 to 2.6.18 in support of the linux-c6 compat ports infrastructure 2032 update. If you wish to continue using the linux-f10 compat ports, 2033 add compat.linux.osrelease=2.6.16 to your local sysctl.conf. Users are 2034 encouraged to update their linux-compat packages to linux-c6 during 2035 their next update cycle. 2036 203720140729: 2038 The ofwfb driver, used to provide a graphics console on PowerPC when 2039 using vt(4), no longer allows mmap() of all physical memory. This 2040 will prevent Xorg on PowerPC with some ATI graphics cards from 2041 initializing properly unless x11-servers/xorg-server is updated to 2042 1.12.4_8 or newer. 2043 204420140723: 2045 The xdev targets have been converted to using TARGET and 2046 TARGET_ARCH instead of XDEV and XDEV_ARCH. 2047 204820140719: 2049 The default unbound configuration has been modified to address 2050 issues with reverse lookups on networks that use private 2051 address ranges. If you use the local_unbound service, run 2052 "service local_unbound setup" as root to regenerate your 2053 configuration, then "service local_unbound reload" to load the 2054 new configuration. 2055 205620140709: 2057 The GNU texinfo and GNU info pages are not built and installed 2058 anymore, WITH_INFO knob has been added to allow to built and install 2059 them again. 2060 UPDATE: see 20150102 entry on texinfo's removal 2061 206220140708: 2063 The GNU readline library is now an INTERNALLIB - that is, it is 2064 statically linked into consumers (GDB and variants) in the base 2065 system, and the shared library is no longer installed. The 2066 devel/readline port is available for third party software that 2067 requires readline. 2068 206920140702: 2070 The Itanium architecture (ia64) has been removed from the list of 2071 known architectures. This is the first step in the removal of the 2072 architecture. 2073 207420140701: 2075 Commit r268115 has added NFSv4.1 server support, merged from 2076 projects/nfsv4.1-server. Since this includes changes to the 2077 internal interfaces between the NFS related modules, a full 2078 build of the kernel and modules will be necessary. 2079 __FreeBSD_version has been bumped. 2080 208120140629: 2082 The WITHOUT_VT_SUPPORT kernel config knob has been renamed 2083 WITHOUT_VT. (The other _SUPPORT knobs have a consistent meaning 2084 which differs from the behaviour controlled by this knob.) 2085 208620140619: 2087 Maximal length of the serial number in CTL was increased from 16 to 2088 64 chars, that breaks ABI. All CTL-related tools, such as ctladm 2089 and ctld, need to be rebuilt to work with a new kernel. 2090 209120140606: 2092 The libatf-c and libatf-c++ major versions were downgraded to 0 and 2093 1 respectively to match the upstream numbers. They were out of 2094 sync because, when they were originally added to FreeBSD, the 2095 upstream versions were not respected. These libraries are private 2096 and not yet built by default, so renumbering them should be a 2097 non-issue. However, unclean source trees will yield broken test 2098 programs once the operator executes "make delete-old-libs" after a 2099 "make installworld". 2100 2101 Additionally, the atf-sh binary was made private by moving it into 2102 /usr/libexec/. Already-built shell test programs will keep the 2103 path to the old binary so they will break after "make delete-old" 2104 is run. 2105 2106 If you are using WITH_TESTS=yes (not the default), wipe the object 2107 tree and rebuild from scratch to prevent spurious test failures. 2108 This is only needed once: the misnumbered libraries and misplaced 2109 binaries have been added to OptionalObsoleteFiles.inc so they will 2110 be removed during a clean upgrade. 2111 211220140512: 2113 Clang and llvm have been upgraded to 3.4.1 release. 2114 211520140508: 2116 We bogusly installed src.opts.mk in /usr/share/mk. This file should 2117 be removed to avoid issues in the future (and has been added to 2118 ObsoleteFiles.inc). 2119 212020140505: 2121 /etc/src.conf now affects only builds of the FreeBSD src tree. In the 2122 past, it affected all builds that used the bsd.*.mk files. The old 2123 behavior was a bug, but people may have relied upon it. To get this 2124 behavior back, you can .include /etc/src.conf from /etc/make.conf 2125 (which is still global and isn't changed). This also changes the 2126 behavior of incremental builds inside the tree of individual 2127 directories. Set MAKESYSPATH to ".../share/mk" to do that. 2128 Although this has survived make universe and some upgrade scenarios, 2129 other upgrade scenarios may have broken. At least one form of 2130 temporary breakage was fixed with MAKESYSPATH settings for buildworld 2131 as well... In cases where MAKESYSPATH isn't working with this 2132 setting, you'll need to set it to the full path to your tree. 2133 2134 One side effect of all this cleaning up is that bsd.compiler.mk 2135 is no longer implicitly included by bsd.own.mk. If you wish to 2136 use COMPILER_TYPE, you must now explicitly include bsd.compiler.mk 2137 as well. 2138 213920140430: 2140 The lindev device has been removed since /dev/full has been made a 2141 standard device. __FreeBSD_version has been bumped. 2142 214320140424: 2144 The knob WITHOUT_VI was added to the base system, which controls 2145 building ex(1), vi(1), etc. Older releases of FreeBSD required ex(1) 2146 in order to reorder files share/termcap and didn't build ex(1) as a 2147 build tool, so building/installing with WITH_VI is highly advised for 2148 build hosts for older releases. 2149 2150 This issue has been fixed in stable/9 and stable/10 in r277022 and 2151 r276991, respectively. 2152 215320140418: 2154 The YES_HESIOD knob has been removed. It has been obsolete for 2155 a decade. Please move to using WITH_HESIOD instead or your builds 2156 will silently lack HESIOD. 2157 215820140405: 2159 The uart(4) driver has been changed with respect to its handling 2160 of the low-level console. Previously the uart(4) driver prevented 2161 any process from changing the baudrate or the CLOCAL and HUPCL 2162 control flags. By removing the restrictions, operators can make 2163 changes to the serial console port without having to reboot. 2164 However, when getty(8) is started on the serial device that is 2165 associated with the low-level console, a misconfigured terminal 2166 line in /etc/ttys will now have a real impact. 2167 Before upgrading the kernel, make sure that /etc/ttys has the 2168 serial console device configured as 3wire without baudrate to 2169 preserve the previous behaviour. E.g: 2170 ttyu0 "/usr/libexec/getty 3wire" vt100 on secure 2171 217220140306: 2173 Support for libwrap (TCP wrappers) in rpcbind was disabled by default 2174 to improve performance. To re-enable it, if needed, run rpcbind 2175 with command line option -W. 2176 217720140226: 2178 Switched back to the GPL dtc compiler due to updates in the upstream 2179 dts files not being supported by the BSDL dtc compiler. You will need 2180 to rebuild your kernel toolchain to pick up the new compiler. Core dumps 2181 may result while building dtb files during a kernel build if you fail 2182 to do so. Set WITHOUT_GPL_DTC if you require the BSDL compiler. 2183 218420140216: 2185 Clang and llvm have been upgraded to 3.4 release. 2186 218720140216: 2188 The nve(4) driver has been removed. Please use the nfe(4) driver 2189 for NVIDIA nForce MCP Ethernet adapters instead. 2190 219120140212: 2192 An ABI incompatibility crept into the libc++ 3.4 import in r261283. 2193 This could cause certain C++ applications using shared libraries built 2194 against the previous version of libc++ to crash. The incompatibility 2195 has now been fixed, but any C++ applications or shared libraries built 2196 between r261283 and r261801 should be recompiled. 2197 219820140204: 2199 OpenSSH will now ignore errors caused by kernel lacking of Capsicum 2200 capability mode support. Please note that enabling the feature in 2201 kernel is still highly recommended. 2202 220320140131: 2204 OpenSSH is now built with sandbox support, and will use sandbox as 2205 the default privilege separation method. This requires Capsicum 2206 capability mode support in kernel. 2207 220820140128: 2209 The libelf and libdwarf libraries have been updated to newer 2210 versions from upstream. Shared library version numbers for 2211 these two libraries were bumped. Any ports or binaries 2212 requiring these two libraries should be recompiled. 2213 __FreeBSD_version is bumped to 1100006. 2214 221520140110: 2216 If a Makefile in a tests/ directory was auto-generating a Kyuafile 2217 instead of providing an explicit one, this would prevent such 2218 Makefile from providing its own Kyuafile in the future during 2219 NO_CLEAN builds. This has been fixed in the Makefiles but manual 2220 intervention is needed to clean an objdir if you use NO_CLEAN: 2221 # find /usr/obj -name Kyuafile | xargs rm -f 2222 222320131213: 2224 The behavior of gss_pseudo_random() for the krb5 mechanism 2225 has changed, for applications requesting a longer random string 2226 than produced by the underlying enctype's pseudo-random() function. 2227 In particular, the random string produced from a session key of 2228 enctype aes256-cts-hmac-sha1-96 or aes256-cts-hmac-sha1-96 will 2229 be different at the 17th octet and later, after this change. 2230 The counter used in the PRF+ construction is now encoded as a 2231 big-endian integer in accordance with RFC 4402. 2232 __FreeBSD_version is bumped to 1100004. 2233 223420131108: 2235 The WITHOUT_ATF build knob has been removed and its functionality 2236 has been subsumed into the more generic WITHOUT_TESTS. If you were 2237 using the former to disable the build of the ATF libraries, you 2238 should change your settings to use the latter. 2239 224020131025: 2241 The default version of mtree is nmtree which is obtained from 2242 NetBSD. The output is generally the same, but may vary 2243 slightly. If you found you need identical output adding 2244 "-F freebsd9" to the command line should do the trick. For the 2245 time being, the old mtree is available as fmtree. 2246 224720131014: 2248 libbsdyml has been renamed to libyaml and moved to /usr/lib/private. 2249 This will break ports-mgmt/pkg. Rebuild the port, or upgrade to pkg 2250 1.1.4_8 and verify bsdyml not linked in, before running "make 2251 delete-old-libs": 2252 # make -C /usr/ports/ports-mgmt/pkg build deinstall install clean 2253 or 2254 # pkg install pkg; ldd /usr/local/sbin/pkg | grep bsdyml 2255 225620131010: 2257 The stable/10 branch has been created in subversion from head 2258 revision r256279. 2259 2260COMMON ITEMS: 2261 2262 General Notes 2263 ------------- 2264 Sometimes, obscure build problems are the result of environment 2265 poisoning. This can happen because the make utility reads its 2266 environment when searching for values for global variables. To run 2267 your build attempts in an "environmental clean room", prefix all make 2268 commands with 'env -i '. See the env(1) manual page for more details. 2269 Occasionally a build failure will occur with "make -j" due to a race 2270 condition. If this happens try building again without -j, and please 2271 report a bug if it happens consistently. 2272 2273 When upgrading from one major version to another it is generally best to 2274 upgrade to the latest code in the currently installed branch first, then 2275 do an upgrade to the new branch. This is the best-tested upgrade path, 2276 and has the highest probability of being successful. Please try this 2277 approach if you encounter problems with a major version upgrade. Since 2278 the stable 4.x branch point, one has generally been able to upgrade from 2279 anywhere in the most recent stable branch to head / current (or even the 2280 last couple of stable branches). See the top of this file when there's 2281 an exception. 2282 2283 The update process will emit an error on an attempt to perform a build 2284 or install from a FreeBSD version below the earliest supported version. 2285 When updating from an older version the update should be performed one 2286 major release at a time, including running `make delete-old` at each 2287 step. 2288 2289 When upgrading a live system, having a root shell around before 2290 installing anything can help undo problems. Not having a root shell 2291 around can lead to problems if pam has changed too much from your 2292 starting point to allow continued authentication after the upgrade. 2293 2294 This file should be read as a log of events. When a later event changes 2295 information of a prior event, the prior event should not be deleted. 2296 Instead, a pointer to the entry with the new information should be 2297 placed in the old entry. Readers of this file should also sanity check 2298 older entries before relying on them blindly. Authors of new entries 2299 should write them with this in mind. 2300 2301 ZFS notes 2302 --------- 2303 When upgrading the boot ZFS pool to a new version, always follow 2304 these two steps: 2305 2306 1.) recompile and reinstall the ZFS boot loader and boot block 2307 (this is part of "make buildworld" and "make installworld") 2308 2309 2.) update the ZFS boot block on your boot drive 2310 2311 The following example updates the ZFS boot block on the 2312 freebsd-boot partition of a GPT partitioned drive ada0: 2313 "gpart bootcode -p /boot/gptzfsboot -i $N ada0" 2314 The value $N will typically be 1 (if booting from BIOS) or 2 (if 2315 booting from EFI). 2316 2317 Non-boot pools do not need these updates. 2318 2319 To build a kernel 2320 ----------------- 2321 If you are updating from a prior version of FreeBSD (even one just 2322 a few days old), you should follow this procedure. It is the most 2323 failsafe as it uses a /usr/obj tree with a fresh mini-buildworld, 2324 2325 make kernel-toolchain 2326 make -DALWAYS_CHECK_MAKE buildkernel KERNCONF=YOUR_KERNEL_HERE 2327 make -DALWAYS_CHECK_MAKE installkernel KERNCONF=YOUR_KERNEL_HERE 2328 2329 To test a kernel once 2330 --------------------- 2331 If you just want to boot a kernel once (because you are not sure 2332 if it works, or if you want to boot a known bad kernel to provide 2333 debugging information) run 2334 make installkernel KERNCONF=YOUR_KERNEL_HERE KODIR=/boot/testkernel 2335 nextboot -k testkernel 2336 2337 To rebuild everything and install it on the current system. 2338 ----------------------------------------------------------- 2339 # Note: sometimes if you are running current you gotta do more than 2340 # is listed here if you are upgrading from a really old current. 2341 2342 <make sure you have good level 0 dumps> 2343 make buildworld 2344 make buildkernel KERNCONF=YOUR_KERNEL_HERE 2345 make installkernel KERNCONF=YOUR_KERNEL_HERE 2346 [1] 2347 <reboot in single user> [3] 2348 mergemaster -Fp [5] 2349 make installworld 2350 mergemaster -Fi [4] 2351 make delete-old [6] 2352 <reboot> 2353 2354 To cross-install current onto a separate partition 2355 -------------------------------------------------- 2356 # In this approach we use a separate partition to hold 2357 # current's root, 'usr', and 'var' directories. A partition 2358 # holding "/", "/usr" and "/var" should be about 2GB in 2359 # size. 2360 2361 <make sure you have good level 0 dumps> 2362 <boot into -stable> 2363 make buildworld 2364 make buildkernel KERNCONF=YOUR_KERNEL_HERE 2365 <maybe newfs current's root partition> 2366 <mount current's root partition on directory ${CURRENT_ROOT}> 2367 make installworld DESTDIR=${CURRENT_ROOT} -DDB_FROM_SRC 2368 make distribution DESTDIR=${CURRENT_ROOT} # if newfs'd 2369 make installkernel KERNCONF=YOUR_KERNEL_HERE DESTDIR=${CURRENT_ROOT} 2370 cp /etc/fstab ${CURRENT_ROOT}/etc/fstab # if newfs'd 2371 <edit ${CURRENT_ROOT}/etc/fstab to mount "/" from the correct partition> 2372 <reboot into current> 2373 <do a "native" rebuild/install as described in the previous section> 2374 <maybe install compatibility libraries from ports/misc/compat*> 2375 <reboot> 2376 2377 2378 To upgrade in-place from stable to current 2379 ---------------------------------------------- 2380 <make sure you have good level 0 dumps> 2381 make buildworld [9] 2382 make buildkernel KERNCONF=YOUR_KERNEL_HERE [8] 2383 make installkernel KERNCONF=YOUR_KERNEL_HERE 2384 [1] 2385 <reboot in single user> [3] 2386 mergemaster -Fp [5] 2387 make installworld 2388 mergemaster -Fi [4] 2389 make delete-old [6] 2390 <reboot> 2391 2392 Make sure that you've read the UPDATING file to understand the 2393 tweaks to various things you need. At this point in the life 2394 cycle of current, things change often and you are on your own 2395 to cope. The defaults can also change, so please read ALL of 2396 the UPDATING entries. 2397 2398 Also, if you are tracking -current, you must be subscribed to 2399 freebsd-current@freebsd.org. Make sure that before you update 2400 your sources that you have read and understood all the recent 2401 messages there. If in doubt, please track -stable which has 2402 much fewer pitfalls. 2403 2404 [1] If you have third party modules, such as vmware, you should disable 2405 them at this point so they don't crash your system on 2406 reboot. Alternatively, you should rebuild all the modules you have in 2407 your system and install them as well. If you are running -current, you 2408 should seriously consider placing all sources to all the modules for 2409 your system (or symlinks to them) in /usr/local/sys/modules so this 2410 happens automatically. If all your modules come from ports, then adding 2411 the port origin directories to PORTS_MODULES instead is also automatic 2412 and effective, eg: 2413 PORTS_MODULES+=x11/nvidia-driver 2414 2415 [3] From the bootblocks, boot -s, and then do 2416 fsck -p 2417 mount -u / 2418 mount -a 2419 sh /etc/rc.d/zfs start # mount zfs filesystem, if needed 2420 cd src # full path to source 2421 adjkerntz -i # if CMOS is wall time 2422 Also, when doing a major release upgrade, it is required that you boot 2423 into single user mode to do the installworld. 2424 2425 [4] Note: This step is non-optional. Failure to do this step 2426 can result in a significant reduction in the functionality of the 2427 system. Attempting to do it by hand is not recommended and those 2428 that pursue this avenue should read this file carefully, as well 2429 as the archives of freebsd-current and freebsd-hackers mailing lists 2430 for potential gotchas. The -U option is also useful to consider. 2431 See mergemaster(8) for more information. 2432 2433 [5] Usually this step is a no-op. However, from time to time 2434 you may need to do this if you get unknown user in the following 2435 step. It never hurts to do it all the time. You may need to 2436 install a new mergemaster (cd src/usr.sbin/mergemaster && make 2437 install) after the buildworld before this step if you last updated 2438 from current before 20130425 or from -stable before 20130430. 2439 2440 [6] This only deletes old files and directories. Old libraries 2441 can be deleted by "make delete-old-libs", but you have to make 2442 sure that no program is using those libraries anymore. 2443 2444 [8] The new kernel must be able to run existing binaries used by an 2445 installworld. When upgrading across major versions, the new kernel's 2446 configuration must include the correct COMPAT_FREEBSD<n> option for 2447 existing binaries (e.g. COMPAT_FREEBSD11 to run 11.x binaries). Failure 2448 to do so may leave you with a system that is hard to boot to recover. A 2449 GENERIC kernel will include suitable compatibility options to run 2450 binaries from older branches. Note that the ability to run binaries 2451 from unsupported branches is not guaranteed. 2452 2453 Make sure that you merge any new devices from GENERIC since the 2454 last time you updated your kernel config file. Options also 2455 change over time, so you may need to adjust your custom kernels 2456 for these as well. 2457 2458 [9] If CPUTYPE is defined in your /etc/make.conf, make sure to use the 2459 "?=" instead of the "=" assignment operator, so that buildworld can 2460 override the CPUTYPE if it needs to. 2461 2462 MAKEOBJDIRPREFIX must be defined in an environment variable, and 2463 not on the command line, or in /etc/make.conf. buildworld will 2464 warn if it is improperly defined. 2465FORMAT: 2466 2467This file contains a list, in reverse chronological order, of major 2468breakages in tracking -current.
