1 Updating Information for FreeBSD stable/13 users. 2 3This file is maintained and copyrighted by M. Warner Losh <[email protected]>. 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://www.freebsd.org/doc/en_US.ISO8859-1/books/handbook/makeworld.html 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 1520210823: 16 As of commit 622809b0868f OpenSSL no longer enables kernel TLS 17 by default. Users can enable kernel TLS via the "KTLS" SSL 18 option. This can be enabled globally by using a custom 19 OpenSSL config file via OPENSSL_CONF or via an 20 application-specific configuration option for applications 21 which permit setting SSL options via SSL_CONF_cmd(3). 22 2320210803: 24 Commits 9fb6e613373c and 9ec7dbf46b0a both changed the internal 25 KAPI between the NFS modules. Bump __FreeBSD_version to 1300514. 26 All NFS modules must be rebuilt from sources. 27 2820210730: 29 Commit b69019c14cd8 removes pf's DIOCGETSTATESNV ioctl. 30 As of be70c7a50d32 it is no longer used by userspace, but it does mean 31 users may not be able to enumerate pf states if they update the kernel 32 past c021ff986e2b without first updating userspace past be70c7a50d32. 33 3420210718: 35 Bump __FreeBSD_version to 1300512 after merging LinuxKPI, OFED, 36 net80211, and driver changes in order to support building 37 Intel wireless iwlwifi drivers. This is especially needed for 38 drm-kmod which needs updates after this. 39 4020210715: 41 The 20210707 awk update brought in a change in behavior. This has 42 been corrected as of d4d252c49976. Between these dates, if you 43 installed a new awk binary, you may not be able to build a new 44 kernel because the change in behavior affected the genoffset 45 script used to build the kernel. If you did update, the fix is 46 to update your sources past the above hash and do 47 % cd usr.bin/awk 48 % make clean all 49 % sudo -E make install 50 to enable building kernels again. 51 5220210711: 53 Commit 8a04edfdcbd2 changes the default minor version 54 used for NFSv4 mounts to the highest minor version supported 55 by the NFSv4 server. This default can be overridden by using 56 the "minorversion" mount option. 57 The consensus of a discussion on freebsd-current@ indicated 58 that this would be acceptable to do and would not be considered 59 a POLA violation. 60 6120210710: 62 awk has been updated to the latest one-true-awk version 20210215. 63 This contains a number of minor bug fixes. 64 6520210630: 66 Commit ca179c4d74f2/632e3f2f3a66 changed the package in which 67 the OpenSSL libraries and utilities are packaged. 68 It is recommended for pkgbase user to do: 69 pkg install -f FreeBSD-openssl 70 before pkg upgrade otherwise some dependencies might not be met 71 and pkg will stop working as libssl will not be present anymore 72 on the system. 73 7420210626: 75 Commit 841006678745 changed the internal KAPI between the krpc 76 and nfsd modules. As such, they must both be rebuilt from 77 sources. 78 __FreeBSD_version is bumped to 1300510. 79 8020210510: 81 Commit 272f39942254 changed the internal KAPI between the 82 nscl.ko and nfscommon.ko modules, so they both need to be 83 rebuilt from sources. 84 8520210429: 86 Commit 5a45802b3c8c changed the internal KAPI between 87 the krpc and NFS. As such, the krpc, nfscommon and 88 nfscl modules must all be rebuilt from sources. 89 Without this patch, NFSv4.1/4.2 mounts should not 90 be done with the nfscbd(8) daemon running, to avoid 91 needing a working back channel for server->client RPCs. 92 9320210202: 94 Various LinuxKPI functionality was added which conflicts with DRM. 95 Please update your drm-kmod port to after the __FreeBSD_verison 1300139 96 update. 97 9820210122: 99 The stable/13 branch has been created from main. 100 10120210108: 102 PC Card attachments for all devices have been removed. In the case of 103 wi and cmx, the entire drivers were removed because they were only 104 PC Card devices. FreeBSD_version 1300134 should be used for this 105 since it was bumped so recently. 106 10720210107: 108 Transport-independent parts of HID support have been split off the USB 109 code in to separate subsystem. Kernel configs which include one of 110 ums, ukbd, uhid, atp, wsp, wmt, uaudio, ugold or ucycom drivers should 111 be updated with adding of "device hid" line. 112 11320210105: 114 ncurses installation has been modified to only keep the widechar 115 enabled version. Incremental build is broken for that change, so it 116 requires a clean build. 117 11820201223: 119 The FreeBSD project has migrated from Subversion to Git. Temporary 120 instructions can be found at 121 https://github.com/bsdimp/freebsd-git-docs/blob/main/src-cvt.md 122 and other documents in that repo. 123 12420201216: 125 The services database has been updated to cover more of the basic 126 services expected in a modern system. The database is big enough 127 that it will cause issues in mergemaster in Releases previous to 128 12.2 and 11.3, or in very old current systems from before r358154. 129 13020201215: 131 Obsolete in-tree GDB 6.1.1 has been removed. GDB (including kgdb) 132 may be installed from ports or packages. 133 13420201124: 135 ping6 has been merged into ping. It can now be called as "ping -6". 136 See ping(8) for details. 137 13820201108: 139 Default value of net.add_addr_allfibs has been changed to 0. 140 If you have multi-fib configuration and rely on existence of all 141 interface routes in every fib, you need to set the above sysctl to 1. 14220201030: 143 The internal pre-processor in the calendar(1) program has been 144 extended to support more C pre-processor commands (e.g. #ifdef, #else, 145 and #undef) and to detect unbalanced conditional statements. 146 Error messages have been extended to include the filename and line 147 number if processing stops to help fixing malformed data files. 148 14920201026: 150 All the data files for the calendar(1) program, except calendar.freebsd, 151 have been moved to the deskutils/calendar-data port, much like the 152 jewish calendar entries were moved to deskutils/hebcal years ago. After 153 make delete-old-files, you need to install it to retain full 154 functionality. calendar(1) will issue a reminder for files it can't 155 find. 156 15720200923: 158 LINT files are no longer generated. We now include the relevant NOTES 159 files. Note: This may cause conflicts with updating in some cases. 160 find sys -name LINT\* -delete 161 is suggested across this commit to remove the generated LINT files. 162 163 If you have tried to update with generated files there, the svn 164 command you want to un-auger the tree is 165 cd sys/amd64/conf 166 svn revert -R . 167 and then do the above find from the top level. Substitute 'amd64' 168 above with where the error message indicates a conflict. 169 17020200824: 171 OpenZFS support has been integrated. Do not upgrade root pools until 172 the loader is updated to support zstd. Furthermore, we caution against 173 'zpool upgrade' for the next few weeks. The change should be transparent 174 unless you want to use new features. 175 176 Not all "NO_CLEAN" build scenarios work across these changes. Many 177 scenarios have been tested and fixed, but rebuilding kernels without 178 rebuilding world may fail. 179 180 The ZFS cache file has moved from /boot to /etc to match the OpenZFS 181 upstream default. A fallback to /boot has been added for mountroot. 182 183 Pool auto import behavior at boot has been moved from the kernel module 184 to an explicit "zpool import -a" in one of the rc scripts enabled by 185 zfs_enable=YES. This means your non-root zpools won't auto import until 186 you upgrade your /etc/rc.d files. 187 18820200824: 189 The resume code now notifies devd with the 'kernel' system 190 rather than the old 'kern' subsystem to be consistent with 191 other use. The old notification will be created as well, but 192 will be removed prior to FreeBSD 14.0. 193 19420200821: 195 r362275 changed the internal API between the kernel RPC and the 196 NFS modules. As such, all the modules must be recompiled from 197 sources. 198 19920200817: 200 r364330 modified the internal API used between the NFS modules. 201 As such, all the NFS modules must be re-compiled from sources. 202 20320200816: 204 Clang, llvm, lld, lldb, compiler-rt, libc++, libunwind and openmp have 205 been upgraded to 11.0.0. Please see the 20141231 entry below for 206 information about prerequisites and upgrading, if you are not already 207 using clang 3.5.0 or higher. 208 20920200810: 210 r364092 modified the internal ABI used between the kernel NFS 211 modules. As such, all of these modules need to be rebuilt 212 from sources, so a version bump was done. 213 21420200807: 215 Makefile.inc has been updated to work around the issue documented in 216 20200729. It was a case where the optimization of using symbolic links 217 to point to binaries created a situation where we'd run new binaries 218 with old libraries starting midway through the installworld process. 219 22020200729: 221 r363679 has redefined some undefined behavior in regcomp(3); notably, 222 extraneous escapes of most ordinary characters will no longer be 223 accepted. An exp-run has identified all of the problems with this in 224 ports, but other non-ports software may need extra escapes removed to 225 continue to function. 226 227 Because of this change, installworld may encounter the following error 228 from rtld: Undefined symbol "regcomp@FBSD_1.6" -- It is imperative that 229 you do not halt installworld. Instead, let it run to completion (whether 230 successful or not) and run installworld once more. 231 23220200627: 233 A new implementation of bc and dc has been imported in r362681. This 234 implementation corrects non-conformant behavior of the previous bc 235 and adds GNU bc compatible options. It offers a number of extensions, 236 is much faster on large values, and has support for message catalogs 237 (a number of languages are already supported, contributions of further 238 languages welcome). The option WITHOUT_GH_BC can be used to build the 239 world with the previous versions of bc and dc. 240 24120200625: 242 r362639 changed the internal API used between the NFS kernel modules. 243 As such, they all need to be rebuilt from sources. 244 24520200613: 246 r362158 changed the arguments for VFS_CHECKEXP(). As such, any 247 out of tree file systems need to be modified and rebuilt. 248 Also, any file systems that are modules must be rebuilt. 249 25020200604: 251 read(2) of a directory fd is now rejected by default. root may 252 re-enable it for system root only on non-ZFS filesystems with the 253 security.bsd.allow_read_dir sysctl(8) MIB if 254 security.bsd.suser_enabled=1. 255 256 It may be advised to setup aliases for grep to default to `-d skip` if 257 commonly non-recursively grepping a list that includes directories and 258 the potential for the resulting stderr output is not tolerable. Example 259 aliases are now installed, commented out, in /root/.cshrc and 260 /root/.shrc. 261 26220200523: 263 Clang, llvm, lld, lldb, compiler-rt, libc++, libunwind and openmp have 264 been upgraded to 10.0.1. Please see the 20141231 entry below for 265 information about prerequisites and upgrading, if you are not already 266 using clang 3.5.0 or higher. 267 26820200512: 269 Support for obsolete compilers has been removed from the build system. 270 Clang 6 and GCC 6.4 are the minimum supported versions. 271 27220200424: 273 closefrom(2) has been moved under COMPAT12, and replaced in libc with a 274 stub that calls close_range(2). If using a custom kernel configuration, 275 you may want to ensure that the COMPAT_FREEBSD12 option is included, as 276 a slightly older -CURRENT userland and older FreeBSD userlands may not 277 be functional without closefrom(2). 278 27920200414: 280 Upstream DTS from Linux 5.6 was merged and they now have the SID 281 and THS (Secure ID controller and THermal Sensor) node present. 282 The DTB overlays have now been removed from the tree for the H3/H5 and 283 A64 SoCs and the aw_sid and aw_thermal driver have been updated to 284 deal with upstream DTS. If you are using those overlays you need to 285 remove them from loader.conf and update the DTBs on the FAT partition. 286 28720200310: 288 Clang, llvm, lld, lldb, compiler-rt, libc++, libunwind and openmp have 289 been upgraded to 10.0.0. Please see the 20141231 entry below for 290 information about prerequisites and upgrading, if you are not already 291 using clang 3.5.0 or higher. 292 29320200309: 294 The amd(8) automount daemon has been removed from the source tree. 295 As of FreeBSD 10.1 autofs(5) is the preferred tool for automounting. 296 amd is still available in the sysutils/am-utils port. 297 29820200301: 299 Removed brooktree driver (bktr.4) from the tree. 300 30120200229: 302 The WITH_GPL_DTC option has been removed. The BSD-licenced device tree 303 compiler in usr.bin/dtc is used on all architectures which use dtc, and 304 the GPL dtc is available (if needed) from the sysutils/dtc port. 305 30620200229: 307 The WITHOUT_LLVM_LIBUNWIND option has been removed. LLVM's libunwind 308 is used by all supported CPU architectures. 309 31020200229: 311 GCC 4.2.1 has been removed from the tree. The WITH_GCC, 312 WITH_GCC_BOOTSTRAP, and WITH_GNUCXX options are no longer available. 313 Users who wish to build FreeBSD with GCC must use the external toolchain 314 ports or packages. 315 31620200220: 317 ncurses has been updated to a newer version (6.2-20200215). Given the ABI 318 has changed, users will have to rebuild all the ports that are linked to 319 ncurses. 320 32120200217: 322 The size of struct vnet and the magic cookie have changed. 323 Users need to recompile libkvm and all modules using VIMAGE 324 together with their new kernel. 325 32620200212: 327 Defining the long deprecated NO_CTF, NO_DEBUG_FILES, NO_INSTALLLIB, 328 NO_MAN, NO_PROFILE, and NO_WARNS variables is now an error. Update 329 your Makefiles and scripts to define MK_<var>=no instead as required. 330 331 One exception to this is that program or library Makefiles should 332 define MAN to empty rather than setting MK_MAN=no. 333 33420200108: 335 Clang/LLVM is now the default compiler and LLD the default 336 linker for riscv64. 337 33820200107: 339 make universe no longer uses GCC 4.2.1 on any architectures. 340 Architectures not supported by in-tree Clang/LLVM require an 341 external toolchain package. 342 34320200104: 344 GCC 4.2.1 is now not built by default, as part of the GCC 4.2.1 345 retirement plan. Specifically, the GCC, GCC_BOOTSTRAP, and GNUCXX 346 options default to off for all supported CPU architectures. As a 347 short-term transition aid they may be enabled via WITH_* options. 348 GCC 4.2.1 is expected to be removed from the tree on 2020-03-31. 349 35020200102: 351 Support for armv5 has been disconnected and is being removed. The 352 machine combination MACHINE=arm MACHINE_ARCH=arm is no longer valid. 353 You must now use a MACHINE_ARCH of armv6 or armv7. The default 354 MACHINE_ARCH for MACHINE=arm is now armv7. 355 35620191226: 357 Clang/LLVM is now the default compiler for all powerpc architectures. 358 LLD is now the default linker for powerpc64. The change for powerpc64 359 also includes a change to the ELFv2 ABI, incompatible with the existing 360 ABI. 361 36220191226: 363 Kernel-loadable random(4) modules are no longer unloadable. 364 36520191222: 366 Clang, llvm, lld, lldb, compiler-rt, libc++, libunwind and openmp have 367 been upgraded to 9.0.1. Please see the 20141231 entry below for 368 information about prerequisites and upgrading, if you are not already 369 using clang 3.5.0 or higher. 370 37120191212: 372 r355677 has modified the internal interface used between the 373 NFS modules in the kernel. As such, they must all be upgraded 374 simultaneously. I will do a version bump for this. 375 37620191205: 377 The root certificates of the Mozilla CA Certificate Store have been 378 imported into the base system and can be managed with the certctl(8) 379 utility. If you have installed the security/ca_root_nss port or package 380 with the ETCSYMLINK option (the default), be advised that there may be 381 differences between those included in the port and those included in 382 base due to differences in nss branch used as well as general update 383 frequency. Note also that certctl(8) cannot manage certs in the 384 format used by the security/ca_root_nss port. 385 38620191120: 387 The amd(8) automount daemon has been disabled by default, and will be 388 removed in the future. As of FreeBSD 10.1 the autofs(5) is available 389 for automounting. 390 39120191107: 392 The nctgpio and wbwd drivers have been moved to the superio bus. 393 If you have one of these drivers in a kernel configuration, then 394 you should add device superio to it. If you use one of these drivers 395 as a module and you compile a custom set of modules, then you should 396 add superio to the set. 397 39820191021: 399 KPIs for network drivers to access interface addresses have changed. 400 Users need to recompile NIC driver modules together with kernel. 401 40220191021: 403 The net.link.tap.user_open sysctl no longer prevents user opening of 404 already created /dev/tapNN devices. Access is still controlled by 405 node permissions, just like tun devices. The net.link.tap.user_open 406 sysctl is now used only to allow users to perform devfs cloning of 407 tap devices, and the subsequent open may not succeed if the user is not 408 in the appropriate group. This sysctl may be deprecated/removed 409 completely in the future. 410 41120191009: 412 mips, powerpc, and sparc64 are no longer built as part of 413 universe / tinderbox unless MAKE_OBSOLETE_GCC is defined. If 414 not defined, mips, powerpc, and sparc64 builds will look for 415 the xtoolchain binaries and if installed use them for universe 416 builds. As llvm 9.0 becomes vetted for these architectures, they 417 will be removed from the list. 418 41920191009: 420 Clang, llvm, lld, lldb, compiler-rt, libc++, libunwind and openmp have 421 been upgraded to 9.0.0. Please see the 20141231 entry below for 422 information about prerequisites and upgrading, if you are not already 423 using clang 3.5.0 or higher. 424 42520191003: 426 The hpt27xx, hptmv, hptnr, and hptrr drivers have been removed from 427 GENERIC. They are available as modules and can be loaded by adding 428 to /boot/loader.conf hpt27xx_load="YES", hptmv_load="YES", 429 hptnr_load="YES", or hptrr_load="YES", respectively. 430 43120190913: 432 ntpd no longer by default locks its pages in memory, allowing them 433 to be paged out by the kernel. Use rlimit memlock to restore 434 historic BSD behaviour. For example, add "rlimit memlock 32" 435 to ntp.conf to lock up to 32 MB of ntpd address space in memory. 436 43720190823: 438 Several of ping6's options have been renamed for better consistency 439 with ping. If you use any of -ARWXaghmrtwx, you must update your 440 scripts. See ping6(8) for details. 441 44220190727: 443 The vfs.fusefs.sync_unmount and vfs.fusefs.init_backgrounded sysctls 444 and the "-o sync_unmount" and "-o init_backgrounded" mount options have 445 been removed from mount_fusefs(8). You can safely remove them from 446 your scripts, because they had no effect. 447 448 The vfs.fusefs.fix_broken_io, vfs.fusefs.sync_resize, 449 vfs.fusefs.refresh_size, vfs.fusefs.mmap_enable, 450 vfs.fusefs.reclaim_revoked, and vfs.fusefs.data_cache_invalidate 451 sysctls have been removed. If you felt the need to set any of them to 452 a non-default value, please tell [email protected] why. 453 45420190713: 455 Default permissions on the /var/account/acct file (and copies of it 456 rotated by periodic daily scripts) are changed from 0644 to 0640 457 because the file contains sensitive information that should not be 458 world-readable. If the /var/account directory must be created by 459 rc.d/accounting, the mode used is now 0750. Admins who use the 460 accounting feature are encouraged to change the mode of an existing 461 /var/account directory to 0750 or 0700. 462 46320190620: 464 Entropy collection and the /dev/random device are no longer optional 465 components. The "device random" option has been removed. 466 Implementations of distilling algorithms can still be made loadable 467 with "options RANDOM_LOADABLE" (e.g., random_fortuna.ko). 468 46920190612: 470 Clang, llvm, lld, lldb, compiler-rt, libc++, libunwind and openmp have 471 been upgraded to 8.0.1. Please see the 20141231 entry below for 472 information about prerequisites and upgrading, if you are not already 473 using clang 3.5.0 or higher. 474 47520190608: 476 A fix was applied to i386 kernel modules to avoid panics with 477 dpcpu or vnet. Users need to recompile i386 kernel modules 478 having pcpu or vnet sections or they will refuse to load. 479 48020190513: 481 User-wired pages now have their own counter, 482 vm.stats.vm.v_user_wire_count. The vm.max_wired sysctl was renamed 483 to vm.max_user_wired and changed from an unsigned int to an unsigned 484 long. bhyve VMs wired with the -S are now subject to the user 485 wiring limit; the vm.max_user_wired sysctl may need to be tuned to 486 avoid running into the limit. 487 48820190507: 489 The IPSEC option has been removed from GENERIC. Users requiring 490 ipsec(4) must now load the ipsec(4) kernel module. 491 49220190507: 493 The tap(4) driver has been folded into tun(4), and the module has been 494 renamed to tuntap. You should update any kld_list="if_tap" or 495 kld_list="if_tun" entries in /etc/rc.conf, if_tap_load="YES" or 496 if_tun_load="YES" entries in /boot/loader.conf to load the if_tuntap 497 module instead, and "device tap" or "device tun" entries in kernel 498 config files to select the tuntap device instead. 499 50020190418: 501 The following knobs have been added related to tradeoffs between 502 safe use of the random device and availability in the absence of 503 entropy: 504 505 kern.random.initial_seeding.bypass_before_seeding: tunable; set 506 non-zero to bypass the random device prior to seeding, or zero to 507 block random requests until the random device is initially seeded. 508 For now, set to 1 (unsafe) by default to restore pre-r346250 boot 509 availability properties. 510 511 kern.random.initial_seeding.read_random_bypassed_before_seeding: 512 read-only diagnostic sysctl that is set when bypass is enabled and 513 read_random(9) is bypassed, to enable programmatic handling of this 514 initial condition, if desired. 515 516 kern.random.initial_seeding.arc4random_bypassed_before_seeding: 517 Similar to the above, but for for arc4random(9) initial seeding. 518 519 kern.random.initial_seeding.disable_bypass_warnings: tunable; set 520 non-zero to disable warnings in dmesg when the same conditions are 521 met as for the diagnostic sysctls above. Defaults to zero, i.e., 522 produce warnings in dmesg when the conditions are met. 523 52420190416: 525 The loadable random module KPI has changed; the random_infra_init() 526 routine now requires a 3rd function pointer for a bool (*)(void) 527 method that returns true if the random device is seeded (and 528 therefore unblocked). 529 53020190404: 531 r345895 reverts r320698. This implies that an nfsuserd(8) daemon 532 built from head sources between r320757 (July 6, 2017) and 533 r338192 (Aug. 22, 2018) will not work unless the "-use-udpsock" 534 is added to the command line. 535 nfsuserd daemons built from head sources that are post-r338192 are 536 not affected and should continue to work. 537 53820190320: 539 The fuse(4) module has been renamed to fusefs(4) for consistency with 540 other filesystems. You should update any kld_load="fuse" entries in 541 /etc/rc.conf, fuse_load="YES" entries in /boot/loader.conf, and 542 "options FUSE" entries in kernel config files. 543 54420190304: 545 Clang, llvm, lld, lldb, compiler-rt and libc++ have been upgraded to 546 8.0.0. Please see the 20141231 entry below for information about 547 prerequisites and upgrading, if you are not already using clang 3.5.0 548 or higher. 549 55020190226: 551 geom_uzip(4) depends on the new module xz. If geom_uzip is statically 552 compiled into your custom kernel, add 'device xz' statement to the 553 kernel config. 554 55520190219: 556 drm and drm2 have been removed from the tree. Please see 557 https://wiki.freebsd.org/Graphics for the latest information on 558 migrating to the drm ports. 559 56020190131: 561 Iflib is no longer unconditionally compiled into the kernel. Drivers 562 using iflib and statically compiled into the kernel, now require 563 the 'device iflib' config option. For the same drivers loaded as 564 modules on kernels not having 'device iflib', the iflib.ko module 565 is loaded automatically. 566 56720190125: 568 The IEEE80211_AMPDU_AGE and AH_SUPPORT_AR5416 kernel configuration 569 options no longer exist since r343219 and r343427 respectively; 570 nothing uses them, so they should be just removed from custom 571 kernel config files. 572 57320181230: 574 r342635 changes the way efibootmgr(8) works by requiring users to add 575 the -b (bootnum) parameter for commands where the bootnum was previously 576 specified with each option. For example 'efibootmgr -B 0001' is now 577 'efibootmgr -B -b 0001'. 578 57920181220: 580 r342286 modifies the NFSv4 server so that it obeys vfs.nfsd.nfs_privport 581 in the same as it is applied to NFSv2 and 3. This implies that NFSv4 582 servers that have vfs.nfsd.nfs_privport set will only allow mounts 583 from clients using a reserved port#. Since both the FreeBSD and Linux 584 NFSv4 clients use reserved port#s by default, this should not affect 585 most NFSv4 mounts. 586 58720181219: 588 The XLP config has been removed. We can't support 64-bit atomics in this 589 kernel because it is running in 32-bit mode. XLP users must transition 590 to running a 64-bit kernel (XLP64 or XLPN32). 591 592 The mips GXEMUL support has been removed from FreeBSD. MALTA* + qemu is 593 the preferred emulator today and we don't need two different ones. 594 595 The old sibyte / swarm / Broadcom BCM1250 support has been 596 removed from the mips port. 597 59820181211: 599 Clang, llvm, lld, lldb, compiler-rt and libc++ have been upgraded to 600 7.0.1. Please see the 20141231 entry below for information about 601 prerequisites and upgrading, if you are not already using clang 3.5.0 602 or higher. 603 60420181211: 605 Remove the timed and netdate programs from the base tree. Setting 606 the time with these daemons has been obsolete for over a decade. 607 60820181126: 609 On amd64, arm64 and armv7 (architectures that install LLVM's ld.lld 610 linker as /usr/bin/ld) GNU ld is no longer installed as ld.bfd, as 611 it produces broken binaries when ifuncs are in use. Users needing 612 GNU ld should install the binutils port or package. 613 61420181123: 615 The BSD crtbegin and crtend code has been enabled by default. It has 616 had extensive testing on amd64, arm64, and i386. It can be disabled 617 by building a world with -DWITHOUT_BSD_CRTBEGIN. 618 61920181115: 620 The set of CTM commands (ctm, ctm_smail, ctm_rmail, ctm_dequeue) 621 has been converted to a port (misc/ctm) and will be removed from 622 FreeBSD-13. It is available as a package (ctm) for all supported 623 FreeBSD versions. 624 62520181110: 626 The default newsyslog.conf(5) file has been changed to only include 627 files in /etc/newsyslog.conf.d/ and /usr/local/etc/newsyslog.conf.d/ if 628 the filenames end in '.conf' and do not begin with a '.'. 629 630 You should check the configuration files in these two directories match 631 this naming convention. You can verify which configuration files are 632 being included using the command: 633 $ newsyslog -Nrv 634 63520181015: 636 Ports for the DRM modules have been simplified. Now, amd64 users should 637 just install the drm-kmod port. All others should install 638 drm-legacy-kmod. 639 640 Graphics hardware that's newer than about 2010 usually works with 641 drm-kmod. For hardware older than 2013, however, some users will need 642 to use drm-legacy-kmod if drm-kmod doesn't work for them. Hardware older 643 than 2008 usually only works in drm-legacy-kmod. The graphics team can 644 only commit to hardware made since 2013 due to the complexity of the 645 market and difficulty to test all the older cards effectively. If you 646 have hardware supported by drm-kmod, you are strongly encouraged to use 647 that as you will get better support. 648 649 Other than KPI chasing, drm-legacy-kmod will not be updated. As outlined 650 elsewhere, the drm and drm2 modules will be eliminated from the src base 651 soon (with a limited exception for arm). Please update to the package 652 asap and report any issues to [email protected]. 653 654 Generally, anybody using the drm*-kmod packages should add 655 WITHOUT_DRM_MODULE=t and WITHOUT_DRM2_MODULE=t to avoid nasty 656 cross-threading surprises, especially with automatic driver 657 loading from X11 startup. These will become the defaults in 13-current 658 shortly. 659 66020181012: 661 The ixlv(4) driver has been renamed to iavf(4). As a consequence, 662 custom kernel and module loading configuration files must be updated 663 accordingly. Moreover, interfaces previous presented as ixlvN to the 664 system are now exposed as iavfN and network configuration files must 665 be adjusted as necessary. 666 66720181009: 668 OpenSSL has been updated to version 1.1.1. This update included 669 additional various API changes throughout the base system. It is 670 important to rebuild third-party software after upgrading. The value 671 of __FreeBSD_version has been bumped accordingly. 672 67320181006: 674 The legacy DRM modules and drivers have now been added to the loader's 675 module blacklist, in favor of loading them with kld_list in rc.conf(5). 676 The module blacklist may be overridden with the loader.conf(5) 677 'module_blacklist' variable, but loading them via rc.conf(5) is strongly 678 encouraged. 679 68020181002: 681 The cam(4) based nda(4) driver will be used over nvd(4) by default on 682 powerpc64. You may set 'options NVME_USE_NVD=1' in your kernel conf or 683 loader tunable 'hw.nvme.use_nvd=1' if you wish to use the existing 684 driver. Make sure to edit /boot/etc/kboot.conf and fstab to use the 685 nda device name. 686 68720180913: 688 Reproducible build mode is now on by default, in preparation for 689 FreeBSD 12.0. This eliminates build metadata such as the user, 690 host, and time from the kernel (and uname), unless the working tree 691 corresponds to a modified checkout from a version control system. 692 The previous behavior can be obtained by setting the /etc/src.conf 693 knob WITHOUT_REPRODUCIBLE_BUILD. 694 69520180826: 696 The Yarrow CSPRNG has been removed from the kernel as it has not been 697 supported by its designers since at least 2003. Fortuna has been the 698 default since FreeBSD-11. 699 70020180822: 701 devctl freeze/thaw have gone into the tree, the rc scripts have been 702 updated to use them and devmatch has been changed. You should update 703 kernel, userland and rc scripts all at the same time. 704 70520180818: 706 The default interpreter has been switched from 4th to Lua. 707 LOADER_DEFAULT_INTERP, documented in build(7), will override the default 708 interpreter. If you have custom FORTH code you will need to set 709 LOADER_DEFAULT_INTERP=4th (valid values are 4th, lua or simp) in 710 src.conf for the build. This will create default hard links between 711 loader and loader_4th instead of loader and loader_lua, the new default. 712 If you are using UEFI it will create the proper hard link to loader.efi. 713 714 bhyve uses userboot.so. It remains 4th-only until some issues are solved 715 regarding coexisting with multiple versions of FreeBSD are resolved. 716 71720180815: 718 ls(1) now respects the COLORTERM environment variable used in other 719 systems and software to indicate that a colored terminal is both 720 supported and desired. If ls(1) is suddenly emitting colors, they may 721 be disabled again by either removing the unwanted COLORTERM from your 722 environment, or using `ls --color=never`. The ls(1) specific CLICOLOR 723 may not be observed in a future release. 724 72520180808: 726 The default pager for most commands has been changed to "less". To 727 restore the old behavior, set PAGER="more" and MANPAGER="more -s" in 728 your environment. 729 73020180731: 731 The jedec_ts(4) driver has been removed. A superset of its functionality 732 is available in the jedec_dimm(4) driver, and the manpage for that 733 driver includes migration instructions. If you have "device jedec_ts" 734 in your kernel configuration file, it must be removed. 735 73620180730: 737 amd64/GENERIC now has EFI runtime services, EFIRT, enabled by default. 738 This should have no effect if the kernel is booted via BIOS/legacy boot. 739 EFIRT may be disabled via a loader tunable, efi.rt.disabled, if a system 740 has a buggy firmware that prevents a successful boot due to use of 741 runtime services. 742 74320180727: 744 Atmel AT91RM9200 and AT91SAM9, Cavium CNS 11xx and XScale 745 support has been removed from the tree. These ports were 746 obsolete and/or known to be broken for many years. 747 74820180723: 749 loader.efi has been augmented to participate more fully in the 750 UEFI boot manager protocol. loader.efi will now look at the 751 BootXXXX environment variable to determine if a specific kernel 752 or root partition was specified. XXXX is derived from BootCurrent. 753 efibootmgr(8) manages these standard UEFI variables. 754 75520180720: 756 zfsloader's functionality has now been folded into loader. 757 zfsloader is no longer necessary once you've updated your 758 boot blocks. For a transition period, we will install a 759 hardlink for zfsloader to loader to allow a smooth transition 760 until the boot blocks can be updated (hard link because old 761 zfs boot blocks don't understand symlinks). 762 76320180719: 764 ARM64 now have efifb support, if you want to have serial console 765 on your arm64 board when an screen is connected and the bootloader 766 setup a frame buffer for us to use, just add : 767 boot_serial=YES 768 boot_multicons=YES 769 in /boot/loader.conf 770 For Raspberry Pi 3 (RPI) users, this is needed even if you don't have 771 an screen connected as the firmware will setup a frame buffer are that 772 u-boot will expose as an EFI frame buffer. 773 77420180719: 775 New uid:gid added, ntpd:ntpd (123:123). Be sure to run mergemaster 776 or take steps to update /etc/passwd before doing installworld on 777 existing systems. Do not skip the "mergemaster -Fp" step before 778 installworld, as described in the update procedures near the bottom 779 of this document. Also, rc.d/ntpd now starts ntpd(8) as user ntpd 780 if the new mac_ntpd(4) policy is available, unless ntpd_flags or 781 the ntp config file contain options that change file/dir locations. 782 When such options (e.g., "statsdir" or "crypto") are used, ntpd can 783 still be run as non-root by setting ntpd_user=ntpd in rc.conf, after 784 taking steps to ensure that all required files/dirs are accessible 785 by the ntpd user. 786 78720180717: 788 Big endian arm support has been removed. 789 79020180711: 791 The static environment setup in kernel configs is no longer mutually 792 exclusive with the loader(8) environment by default. In order to 793 restore the previous default behavior of disabling the loader(8) 794 environment if a static environment is present, you must specify 795 loader_env.disabled=1 in the static environment. 796 79720180705: 798 The ABI of syscalls used by management tools like sockstat and 799 netstat has been broken to allow 32-bit binaries to work on 800 64-bit kernels without modification. These programs will need 801 to match the kernel in order to function. External programs may 802 require minor modifications to accommodate a change of type in 803 structures from pointers to 64-bit virtual addresses. 804 80520180702: 806 On i386 and amd64 atomics are now inlined. Out of tree modules using 807 atomics will need to be rebuilt. 808 80920180701: 810 The '%I' format in the kern.corefile sysctl limits the number of 811 core files that a process can generate to the number stored in the 812 debug.ncores sysctl. The '%I' format is replaced by the single digit 813 index. Previously, if all indexes were taken the kernel would overwrite 814 only a core file with the highest index in a filename. 815 Currently the system will create a new core file if there is a free 816 index or if all slots are taken it will overwrite the oldest one. 817 81820180630: 819 Clang, llvm, lld, lldb, compiler-rt and libc++ have been upgraded to 820 6.0.1. Please see the 20141231 entry below for information about 821 prerequisites and upgrading, if you are not already using clang 3.5.0 822 or higher. 823 82420180628: 825 r335753 introduced a new quoting method. However, etc/devd/devmatch.conf 826 needed to be changed to work with it. This change was made with r335763 827 and requires a mergemaster / etcupdate / etc to update the installed 828 file. 829 83020180612: 831 r334930 changed the interface between the NFS modules, so they all 832 need to be rebuilt. r335018 did a __FreeBSD_version bump for this. 833 83420180530: 835 As of r334391 lld is the default amd64 system linker; it is installed 836 as /usr/bin/ld. Kernel build workarounds (see 20180510 entry) are no 837 longer necessary. 838 83920180530: 840 The kernel / userland interface for devinfo changed, so you'll 841 need a new kernel and userland as a pair for it to work (rebuilding 842 lib/libdevinfo is all that's required). devinfo and devmatch will 843 not work, but everything else will when there's a mismatch. 844 84520180523: 846 The on-disk format for hwpmc callchain records has changed to include 847 threadid corresponding to a given record. This changes the field offsets 848 and thus requires that libpmcstat be rebuilt before using a kernel 849 later than r334108. 850 85120180517: 852 The vxge(4) driver has been removed. This driver was introduced into 853 HEAD one week before the Exar left the Ethernet market and is not 854 known to be used. If you have device vxge in your kernel config file 855 it must be removed. 856 85720180510: 858 The amd64 kernel now requires a ld that supports ifunc to produce a 859 working kernel, either lld or a newer binutils. lld is built by default 860 on amd64, and the 'buildkernel' target uses it automatically. However, 861 it is not the default linker, so building the kernel the traditional 862 way requires LD=ld.lld on the command line (or LD=/usr/local/bin/ld for 863 binutils port/package). lld will soon be default, and this requirement 864 will go away. 865 866 NOTE: As of r334391 lld is the default system linker on amd64, and no 867 workaround is necessary. 868 86920180508: 870 The nxge(4) driver has been removed. This driver was for PCI-X 10g 871 cards made by s2io/Neterion. The company was acquired by Exar and 872 no longer sells or supports Ethernet products. If you have device 873 nxge in your kernel config file it must be removed. 874 87520180504: 876 The tz database (tzdb) has been updated to 2018e. This version more 877 correctly models time stamps in time zones with negative DST such as 878 Europe/Dublin (from 1971 on), Europe/Prague (1946/7), and 879 Africa/Windhoek (1994/2017). This does not affect the UT offsets, only 880 time zone abbreviations and the tm_isdst flag. 881 88220180502: 883 The ixgb(4) driver has been removed. This driver was for an early and 884 uncommon legacy PCI 10GbE for a single ASIC, Intel 82597EX. Intel 885 quickly shifted to the long lived ixgbe family. If you have device 886 ixgb in your kernel config file it must be removed. 887 88820180501: 889 The lmc(4) driver has been removed. This was a WAN interface 890 card that was already reportedly rare in 2003, and had an ambiguous 891 license. If you have device lmc in your kernel config file it must 892 be removed. 893 89420180413: 895 Support for Arcnet networks has been removed. If you have device 896 arcnet or device cm in your kernel config file they must be 897 removed. 898 89920180411: 900 Support for FDDI networks has been removed. If you have device 901 fddi or device fpa in your kernel config file they must be 902 removed. 903 90420180406: 905 In addition to supporting RFC 3164 formatted messages, the 906 syslogd(8) service is now capable of parsing RFC 5424 formatted 907 log messages. The main benefit of using RFC 5424 is that clients 908 may now send log messages with timestamps containing year numbers, 909 microseconds and time zone offsets. 910 911 Similarly, the syslog(3) C library function has been altered to 912 send RFC 5424 formatted messages to the local system logging 913 daemon. On systems using syslogd(8), this change should have no 914 negative impact, as long as syslogd(8) and the C library are 915 updated at the same time. On systems using a different system 916 logging daemon, it may be necessary to make configuration 917 adjustments, depending on the software used. 918 919 When using syslog-ng, add the 'syslog-protocol' flag to local 920 input sources to enable parsing of RFC 5424 formatted messages: 921 922 source src { 923 unix-dgram("/var/run/log" flags(syslog-protocol)); 924 } 925 926 When using rsyslog, disable the 'SysSock.UseSpecialParser' option 927 of the 'imuxsock' module to let messages be processed by the 928 regular RFC 3164/5424 parsing pipeline: 929 930 module(load="imuxsock" SysSock.UseSpecialParser="off") 931 932 Do note that these changes only affect communication between local 933 applications and syslogd(8). The format that syslogd(8) uses to 934 store messages on disk or forward messages to other systems 935 remains unchanged. syslogd(8) still uses RFC 3164 for these 936 purposes. Options to customize this behaviour will be added in the 937 future. Utilities that process log files stored in /var/log are 938 thus expected to continue to function as before. 939 940 __FreeBSD_version has been incremented to 1200061 to denote this 941 change. 942 94320180328: 944 Support for token ring networks has been removed. If you 945 have "device token" in your kernel config you should remove 946 it. No device drivers supported token ring. 947 94820180323: 949 makefs was modified to be able to tag ISO9660 El Torito boot catalog 950 entries as EFI instead of overloading the i386 tag as done previously. 951 The amd64 mkisoimages.sh script used to build amd64 ISO images for 952 release was updated to use this. This may mean that makefs must be 953 updated before "make cdrom" can be run in the release directory. This 954 should be as simple as: 955 956 $ cd $SRCDIR/usr.sbin/makefs 957 $ make depend all install 958 95920180212: 960 FreeBSD boot loader enhanced with Lua scripting. It's purely opt-in for 961 now by building WITH_LOADER_LUA and WITHOUT_FORTH in /etc/src.conf. 962 Co-existence for the transition period will come shortly. Booting is a 963 complex environment and test coverage for Lua-enabled loaders has been 964 thin, so it would be prudent to assume it might not work and make 965 provisions for backup boot methods. 966 96720180211: 968 devmatch functionality has been turned on in devd. It will automatically 969 load drivers for unattached devices. This may cause unexpected drivers 970 to be loaded. Please report any problems to current@ and 971 [email protected]. 972 97320180114: 974 Clang, llvm, lld, lldb, compiler-rt and libc++ have been upgraded to 975 6.0.0. Please see the 20141231 entry below for information about 976 prerequisites and upgrading, if you are not already using clang 3.5.0 977 or higher. 978 97920180110: 980 LLVM's lld linker is now used as the FreeBSD/amd64 bootstrap linker. 981 This means it is used to link the kernel and userland libraries and 982 executables, but is not yet installed as /usr/bin/ld by default. 983 984 To revert to ld.bfd as the bootstrap linker, in /etc/src.conf set 985 WITHOUT_LLD_BOOTSTRAP=yes 986 98720180110: 988 On i386, pmtimer has been removed. Its functionality has been folded 989 into apm. It was a no-op on ACPI in current for a while now (but was 990 still needed on i386 in FreeBSD 11 and earlier). Users may need to 991 remove it from kernel config files. 992 99320180104: 994 The use of RSS hash from the network card aka flowid has been 995 disabled by default for lagg(4) as it's currently incompatible with 996 the lacp and loadbalance protocols. 997 998 This can be re-enabled by setting the following in loader.conf: 999 net.link.lagg.default_use_flowid="1" 1000 100120180102: 1002 The SW_WATCHDOG option is no longer necessary to enable the 1003 hardclock-based software watchdog if no hardware watchdog is 1004 configured. As before, SW_WATCHDOG will cause the software 1005 watchdog to be enabled even if a hardware watchdog is configured. 1006 100720171215: 1008 r326887 fixes the issue described in the 20171214 UPDATING entry. 1009 r326888 flips the switch back to building GELI support always. 1010 101120171214: 1012 r362593 broke ZFS + GELI support for reasons unknown. However, 1013 it also broke ZFS support generally, so GELI has been turned off 1014 by default as the lesser evil in r326857. If you boot off ZFS and/or 1015 GELI, it might not be a good time to update. 1016 101720171125: 1018 PowerPC users must update loader(8) by rebuilding world before 1019 installing a new kernel, as the protocol connecting them has 1020 changed. Without the update, loader metadata will not be passed 1021 successfully to the kernel and users will have to enter their 1022 root partition at the kernel mountroot prompt to continue booting. 1023 Newer versions of loader can boot old kernels without issue. 1024 102520171110: 1026 The LOADER_FIREWIRE_SUPPORT build variable as been renamed to 1027 WITH/OUT_LOADER_FIREWIRE. LOADER_{NO_,}GELI_SUPPORT has been renamed 1028 to WITH/OUT_LOADER_GELI. 1029 103020171106: 1031 The naive and non-compliant support of posix_fallocate(2) in ZFS 1032 has been removed as of r325320. The system call now returns EINVAL 1033 when used on a ZFS file. Although the new behavior complies with the 1034 standard, some consumers are not prepared to cope with it. 1035 One known victim is lld prior to r325420. 1036 103720171102: 1038 Building in a FreeBSD src checkout will automatically create object 1039 directories now rather than store files in the current directory if 1040 'make obj' was not ran. Calling 'make obj' is no longer necessary. 1041 This feature can be disabled by setting WITHOUT_AUTO_OBJ=yes in 1042 /etc/src-env.conf (not /etc/src.conf), or passing the option in the 1043 environment. 1044 104520171101: 1046 The default MAKEOBJDIR has changed from /usr/obj/<srcdir> for native 1047 builds, and /usr/obj/<arch>/<srcdir> for cross-builds, to a unified 1048 /usr/obj/<srcdir>/<arch>. This behavior can be changed to the old 1049 format by setting WITHOUT_UNIFIED_OBJDIR=yes in /etc/src-env.conf, 1050 the environment, or with -DWITHOUT_UNIFIED_OBJDIR when building. 1051 The UNIFIED_OBJDIR option is a transitional feature that will be 1052 removed for 12.0 release; please migrate to the new format for any 1053 tools by looking up the OBJDIR used by 'make -V .OBJDIR' means rather 1054 than hardcoding paths. 1055 105620171028: 1057 The native-xtools target no longer installs the files by default to the 1058 OBJDIR. Use the native-xtools-install target with a DESTDIR to install 1059 to ${DESTDIR}/${NXTP} where NXTP defaults to /nxb-bin. 1060 106120171021: 1062 As part of the boot loader infrastructure cleanup, LOADER_*_SUPPORT 1063 options are changing from controlling the build if defined / undefined 1064 to controlling the build with explicit 'yes' or 'no' values. They will 1065 shift to WITH/WITHOUT options to match other options in the system. 1066 106720171010: 1068 libstand has turned into a private library for sys/boot use only. 1069 It is no longer supported as a public interface outside of sys/boot. 1070 107120171005: 1072 The arm port has split armv6 into armv6 and armv7. armv7 is now 1073 a valid TARGET_ARCH/MACHINE_ARCH setting. If you have an armv7 system 1074 and are running a kernel from before r324363, you will need to add 1075 MACHINE_ARCH=armv7 to 'make buildworld' to do a native build. 1076 107720171003: 1078 When building multiple kernels using KERNCONF, non-existent KERNCONF 1079 files will produce an error and buildkernel will fail. Previously 1080 missing KERNCONF files silently failed giving no indication as to 1081 why, only to subsequently discover during installkernel that the 1082 desired kernel was never built in the first place. 1083 108420170912: 1085 The default serial number format for CTL LUNs has changed. This will 1086 affect users who use /dev/diskid/* device nodes, or whose FibreChannel 1087 or iSCSI clients care about their LUNs' serial numbers. Users who 1088 require serial number stability should hardcode serial numbers in 1089 /etc/ctl.conf . 1090 109120170912: 1092 For 32-bit arm compiled for hard-float support, soft-floating point 1093 binaries now always get their shared libraries from 1094 LD_SOFT_LIBRARY_PATH (in the past, this was only used if 1095 /usr/libsoft also existed). Only users with a hard-float ld.so, but 1096 soft-float everything else should be affected. 1097 109820170826: 1099 The geli password typed at boot is now hidden. To restore the previous 1100 behavior, see geli(8) for configuration options. 1101 110220170825: 1103 Move PMTUD blackhole counters to TCPSTATS and remove them from bare 1104 sysctl values. Minor nit, but requires a rebuild of both world/kernel 1105 to complete. 1106 110720170814: 1108 "make check" behavior (made in ^/head@r295380) has been changed to 1109 execute from a limited sandbox, as opposed to executing from 1110 ${TESTSDIR}. 1111 1112 Behavioral changes: 1113 - The "beforecheck" and "aftercheck" targets are now specified. 1114 - ${CHECKDIR} (added in commit noted above) has been removed. 1115 - Legacy behavior can be enabled by setting 1116 WITHOUT_MAKE_CHECK_USE_SANDBOX in src.conf(5) or the environment. 1117 1118 If the limited sandbox mode is enabled, "make check" will execute 1119 "make distribution", then install, execute the tests, and clean up the 1120 sandbox if successful. 1121 1122 The "make distribution" and "make install" targets are typically run as 1123 root to set appropriate permissions and ownership at installation time. 1124 The end-user should set "WITH_INSTALL_AS_USER" in src.conf(5) or the 1125 environment if executing "make check" with limited sandbox mode using 1126 an unprivileged user. 1127 112820170808: 1129 Since the switch to GPT disk labels, fsck for UFS/FFS has been 1130 unable to automatically find alternate superblocks. As of r322297, 1131 the information needed to find alternate superblocks has been 1132 moved to the end of the area reserved for the boot block. 1133 Filesystems created with a newfs of this vintage or later 1134 will create the recovery information. If you have a filesystem 1135 created prior to this change and wish to have a recovery block 1136 created for your filesystem, you can do so by running fsck in 1137 foreground mode (i.e., do not use the -p or -y options). As it 1138 starts, fsck will ask ``SAVE DATA TO FIND ALTERNATE SUPERBLOCKS'' 1139 to which you should answer yes. 1140 114120170728: 1142 As of r321665, an NFSv4 server configuration that services 1143 Kerberos mounts or clients that do not support the uid/gid in 1144 owner/owner_group string capability, must explicitly enable 1145 the nfsuserd daemon by adding nfsuserd_enable="YES" to the 1146 machine's /etc/rc.conf file. 1147 114820170722: 1149 Clang, llvm, lldb, compiler-rt and libc++ have been upgraded to 5.0.0. 1150 Please see the 20141231 entry below for information about prerequisites 1151 and upgrading, if you are not already using clang 3.5.0 or higher. 1152 115320170701: 1154 WITHOUT_RCMDS is now the default. Set WITH_RCMDS if you need the 1155 r-commands (rlogin, rsh, etc.) to be built with the base system. 1156 115720170625: 1158 The FreeBSD/powerpc platform now uses a 64-bit type for time_t. This is 1159 a very major ABI incompatible change, so users of FreeBSD/powerpc must 1160 be careful when performing source upgrades. It is best to run 1161 'make installworld' from an alternate root system, either a live 1162 CD/memory stick, or a temporary root partition. Additionally, all ports 1163 must be recompiled. powerpc64 is largely unaffected, except in the case 1164 of 32-bit compatibility. All 32-bit binaries will be affected. 1165 116620170623: 1167 Forward compatibility for the "ino64" project have been committed. This 1168 will allow most new binaries to run on older kernels in a limited 1169 fashion. This prevents many of the common foot-shooting actions in the 1170 upgrade as well as the limited ability to roll back the kernel across 1171 the ino64 upgrade. Complicated use cases may not work properly, though 1172 enough simpler ones work to allow recovery in most situations. 1173 117420170620: 1175 Switch back to the BSDL dtc (Device Tree Compiler). Set WITH_GPL_DTC 1176 if you require the GPL compiler. 1177 117820170618: 1179 The internal ABI used for communication between the NFS kernel modules 1180 was changed by r320085, so __FreeBSD_version was bumped to 1181 ensure all the NFS related modules are updated together. 1182 118320170617: 1184 The ABI of struct event was changed by extending the data 1185 member to 64bit and adding ext fields. For upgrade, same 1186 precautions as for the entry 20170523 "ino64" must be 1187 followed. 1188 118920170531: 1190 The GNU roff toolchain has been removed from base. To render manpages 1191 which are not supported by mandoc(1), man(1) can fallback on GNU roff 1192 from ports (and recommends to install it). 1193 To render roff(7) documents, consider using GNU roff from ports or the 1194 heirloom doctools roff toolchain from ports via pkg install groff or 1195 via pkg install heirloom-doctools. 1196 119720170524: 1198 The ath(4) and ath_hal(4) modules now build piecemeal to allow for 1199 smaller runtime footprint builds. This is useful for embedded systems 1200 which only require one chipset support. 1201 1202 If you load it as a module, make sure this is in /boot/loader.conf: 1203 1204 if_ath_load="YES" 1205 1206 This will load the HAL, all chip/RF backends and if_ath_pci. 1207 If you have if_ath_pci in /boot/loader.conf, ensure it is after 1208 if_ath or it will not load any HAL chipset support. 1209 1210 If you want to selectively load things (eg on ye cheape ARM/MIPS 1211 platforms where RAM is at a premium) you should: 1212 1213 * load ath_hal 1214 * load the chip modules in question 1215 * load ath_rate, ath_dfs 1216 * load ath_main 1217 * load if_ath_pci and/or if_ath_ahb depending upon your particular 1218 bus bind type - this is where probe/attach is done. 1219 1220 For further comments/feedback, poke adrian@ . 1221 122220170523: 1223 The "ino64" 64-bit inode project has been committed, which extends 1224 a number of types to 64 bits. Upgrading in place requires care and 1225 adherence to the documented upgrade procedure. 1226 1227 If using a custom kernel configuration ensure that the 1228 COMPAT_FREEBSD11 option is included (as during the upgrade the 1229 system will be running the ino64 kernel with the existing world). 1230 1231 For the safest in-place upgrade begin by removing previous build 1232 artifacts via "rm -rf /usr/obj/*". Then, carefully follow the full 1233 procedure documented below under the heading "To rebuild everything and 1234 install it on the current system." Specifically, a reboot is required 1235 after installing the new kernel before installing world. While an 1236 installworld normally works by accident from multiuser after rebooting 1237 the proper kernel, there are many cases where this will fail across this 1238 upgrade and installworld from single user is required. 1239 124020170424: 1241 The NATM framework including the en(4), fatm(4), hatm(4), and 1242 patm(4) devices has been removed. Consumers should plan a 1243 migration before the end-of-life date for FreeBSD 11. 1244 124520170420: 1246 GNU diff has been replaced by a BSD licensed diff. Some features of GNU 1247 diff has not been implemented, if those are needed a newer version of 1248 GNU diff is available via the diffutils package under the gdiff name. 1249 125020170413: 1251 As of r316810 for ipfilter, keep frags is no longer assumed when 1252 keep state is specified in a rule. r316810 aligns ipfilter with 1253 documentation in man pages separating keep frags from keep state. 1254 This allows keep state to be specified without forcing keep frags 1255 and allows keep frags to be specified independently of keep state. 1256 To maintain previous behaviour, also specify keep frags with 1257 keep state (as documented in ipf.conf.5). 1258 125920170407: 1260 arm64 builds now use the base system LLD 4.0.0 linker by default, 1261 instead of requiring that the aarch64-binutils port or package be 1262 installed. To continue using aarch64-binutils, set 1263 CROSS_BINUTILS_PREFIX=/usr/local/aarch64-freebsd/bin . 1264 126520170405: 1266 The UDP optimization in entry 20160818 that added the sysctl 1267 net.inet.udp.require_l2_bcast has been reverted. L2 broadcast 1268 packets will no longer be treated as L3 broadcast packets. 1269 127020170331: 1271 Binds and sends to the loopback addresses, IPv6 and IPv4, will now 1272 use any explicitly assigned loopback address available in the jail 1273 instead of using the first assigned address of the jail. 1274 127520170329: 1276 The ctl.ko module no longer implements the iSCSI target frontend: 1277 cfiscsi.ko does instead. 1278 1279 If building cfiscsi.ko as a kernel module, the module can be loaded 1280 via one of the following methods: 1281 - `cfiscsi_load="YES"` in loader.conf(5). 1282 - Add `cfiscsi` to `$kld_list` in rc.conf(5). 1283 - ctladm(8)/ctld(8), when compiled with iSCSI support 1284 (`WITH_ISCSI=yes` in src.conf(5)) 1285 1286 Please see cfiscsi(4) for more details. 1287 128820170316: 1289 The mmcsd.ko module now additionally depends on geom_flashmap.ko. 1290 Also, mmc.ko and mmcsd.ko need to be a matching pair built from the 1291 same source (previously, the dependency of mmcsd.ko on mmc.ko was 1292 missing, but mmcsd.ko now will refuse to load if it is incompatible 1293 with mmc.ko). 1294 129520170315: 1296 The syntax of ipfw(8) named states was changed to avoid ambiguity. 1297 If you have used named states in the firewall rules, you need to modify 1298 them after installworld and before rebooting. Now named states must 1299 be prefixed with colon. 1300 130120170311: 1302 The old drm (sys/dev/drm/) drivers for i915 and radeon have been 1303 removed as the userland we provide cannot use them. The KMS version 1304 (sys/dev/drm2) supports the same hardware. 1305 130620170302: 1307 Clang, llvm, lldb, compiler-rt and libc++ have been upgraded to 4.0.0. 1308 Please see the 20141231 entry below for information about prerequisites 1309 and upgrading, if you are not already using clang 3.5.0 or higher. 1310 131120170221: 1312 The code that provides support for ZFS .zfs/ directory functionality 1313 has been reimplemented. It's not possible now to create a snapshot 1314 by mkdir under .zfs/snapshot/. That should be the only user visible 1315 change. 1316 131720170216: 1318 EISA bus support has been removed. The WITH_EISA option is no longer 1319 valid. 1320 132120170215: 1322 MCA bus support has been removed. 1323 132420170127: 1325 The WITH_LLD_AS_LD / WITHOUT_LLD_AS_LD build knobs have been renamed 1326 WITH_LLD_IS_LD / WITHOUT_LLD_IS_LD, for consistency with CLANG_IS_CC. 1327 132820170112: 1329 The EM_MULTIQUEUE kernel configuration option is deprecated now that 1330 the em(4) driver conforms to iflib specifications. 1331 133220170109: 1333 The igb(4), em(4) and lem(4) ethernet drivers are now implemented via 1334 IFLIB. If you have a custom kernel configuration that excludes em(4) 1335 but you use igb(4), you need to re-add em(4) to your custom 1336 configuration. 1337 133820161217: 1339 Clang, llvm, lldb, compiler-rt and libc++ have been upgraded to 3.9.1. 1340 Please see the 20141231 entry below for information about prerequisites 1341 and upgrading, if you are not already using clang 3.5.0 or higher. 1342 134320161124: 1344 Clang, llvm, lldb, compiler-rt and libc++ have been upgraded to 3.9.0. 1345 Please see the 20141231 entry below for information about prerequisites 1346 and upgrading, if you are not already using clang 3.5.0 or higher. 1347 134820161119: 1349 The layout of the pmap structure has changed for powerpc to put the pmap 1350 statistics at the front for all CPU variations. libkvm(3) and all tools 1351 that link against it need to be recompiled. 1352 135320161030: 1354 isl(4) and cyapa(4) drivers now require a new driver, 1355 chromebook_platform(4), to work properly on Chromebook-class hardware. 1356 On other types of hardware the drivers may need to be configured using 1357 device hints. Please see the corresponding manual pages for details. 1358 135920161017: 1360 The urtwn(4) driver was merged into rtwn(4) and now consists of 1361 rtwn(4) main module + rtwn_usb(4) and rtwn_pci(4) bus-specific 1362 parts. 1363 Also, firmware for RTL8188CE was renamed due to possible name 1364 conflict (rtwnrtl8192cU(B) -> rtwnrtl8192cE(B)) 1365 136620161015: 1367 GNU rcs has been removed from base. It is available as packages: 1368 - rcs: Latest GPLv3 GNU rcs version. 1369 - rcs57: Copy of the latest version of GNU rcs (GPLv2) before it was 1370 removed from base. 1371 137220161008: 1373 Use of the cc_cdg, cc_chd, cc_hd, or cc_vegas congestion control 1374 modules now requires that the kernel configuration contain the 1375 TCP_HHOOK option. (This option is included in the GENERIC kernel.) 1376 137720161003: 1378 The WITHOUT_ELFCOPY_AS_OBJCOPY src.conf(5) knob has been retired. 1379 ELF Tool Chain's elfcopy is always installed as /usr/bin/objcopy. 1380 138120160924: 1382 Relocatable object files with the extension of .So have been renamed 1383 to use an extension of .pico instead. The purpose of this change is 1384 to avoid a name clash with shared libraries on case-insensitive file 1385 systems. On those file systems, foo.So is the same file as foo.so. 1386 138720160918: 1388 GNU rcs has been turned off by default. It can (temporarily) be built 1389 again by adding WITH_RCS knob in src.conf. 1390 Otherwise, GNU rcs is available from packages: 1391 - rcs: Latest GPLv3 GNU rcs version. 1392 - rcs57: Copy of the latest version of GNU rcs (GPLv2) from base. 1393 139420160918: 1395 The backup_uses_rcs functionality has been removed from rc.subr. 1396 139720160908: 1398 The queue(3) debugging macro, QUEUE_MACRO_DEBUG, has been split into 1399 two separate components, QUEUE_MACRO_DEBUG_TRACE and 1400 QUEUE_MACRO_DEBUG_TRASH. Define both for the original 1401 QUEUE_MACRO_DEBUG behavior. 1402 140320160824: 1404 r304787 changed some ioctl interfaces between the iSCSI userspace 1405 programs and the kernel. ctladm, ctld, iscsictl, and iscsid must be 1406 rebuilt to work with new kernels. __FreeBSD_version has been bumped 1407 to 1200005. 1408 140920160818: 1410 The UDP receive code has been updated to only treat incoming UDP 1411 packets that were addressed to an L2 broadcast address as L3 1412 broadcast packets. It is not expected that this will affect any 1413 standards-conforming UDP application. The new behaviour can be 1414 disabled by setting the sysctl net.inet.udp.require_l2_bcast to 1415 0. 1416 141720160818: 1418 Remove the openbsd_poll system call. 1419 __FreeBSD_version has been bumped because of this. 1420 142120160708: 1422 The stable/11 branch has been created from head@r302406. 1423 142420160622: 1425 The libc stub for the pipe(2) system call has been replaced with 1426 a wrapper that calls the pipe2(2) system call and the pipe(2) 1427 system call is now only implemented by the kernels that include 1428 "options COMPAT_FREEBSD10" in their config file (this is the 1429 default). Users should ensure that this option is enabled in 1430 their kernel or upgrade userspace to r302092 before upgrading their 1431 kernel. 1432 143320160527: 1434 CAM will now strip leading spaces from SCSI disks' serial numbers. 1435 This will affect users who create UFS filesystems on SCSI disks using 1436 those disk's diskid device nodes. For example, if /etc/fstab 1437 previously contained a line like 1438 "/dev/diskid/DISK-%20%20%20%20%20%20%20ABCDEFG0123456", you should 1439 change it to "/dev/diskid/DISK-ABCDEFG0123456". Users of geom 1440 transforms like gmirror may also be affected. ZFS users should 1441 generally be fine. 1442 144320160523: 1444 The bitstring(3) API has been updated with new functionality and 1445 improved performance. But it is binary-incompatible with the old API. 1446 Objects built with the new headers may not be linked against objects 1447 built with the old headers. 1448 144920160520: 1450 The brk and sbrk functions have been removed from libc on arm64. 1451 Binutils from ports has been updated to not link to these 1452 functions and should be updated to the latest version before 1453 installing a new libc. 1454 145520160517: 1456 The armv6 port now defaults to hard float ABI. Limited support 1457 for running both hardfloat and soft float on the same system 1458 is available using the libraries installed with -DWITH_LIBSOFT. 1459 This has only been tested as an upgrade path for installworld 1460 and packages may fail or need manual intervention to run. New 1461 packages will be needed. 1462 1463 To update an existing self-hosted armv6hf system, you must add 1464 TARGET_ARCH=armv6 on the make command line for both the build 1465 and the install steps. 1466 146720160510: 1468 Kernel modules compiled outside of a kernel build now default to 1469 installing to /boot/modules instead of /boot/kernel. Many kernel 1470 modules built this way (such as those in ports) already overrode 1471 KMODDIR explicitly to install into /boot/modules. However, 1472 manually building and installing a module from /sys/modules will 1473 now install to /boot/modules instead of /boot/kernel. 1474 147520160414: 1476 The CAM I/O scheduler has been committed to the kernel. There should be 1477 no user visible impact. This does enable NCQ Trim on ada SSDs. While the 1478 list of known rogues that claim support for this but actually corrupt 1479 data is believed to be complete, be on the lookout for data 1480 corruption. The known rogue list is believed to be complete: 1481 1482 o Crucial MX100, M550 drives with MU01 firmware. 1483 o Micron M510 and M550 drives with MU01 firmware. 1484 o Micron M500 prior to MU07 firmware 1485 o Samsung 830, 840, and 850 all firmwares 1486 o FCCT M500 all firmwares 1487 1488 Crucial has firmware http://www.crucial.com/usa/en/support-ssd-firmware 1489 with working NCQ TRIM. For Micron branded drives, see your sales rep for 1490 updated firmware. Black listed drives will work correctly because these 1491 drives work correctly so long as no NCQ TRIMs are sent to them. Given 1492 this list is the same as found in Linux, it's believed there are no 1493 other rogues in the market place. All other models from the above 1494 vendors work. 1495 1496 To be safe, if you are at all concerned, you can quirk each of your 1497 drives to prevent NCQ from being sent by setting: 1498 kern.cam.ada.X.quirks="0x2" 1499 in loader.conf. If the drive requires the 4k sector quirk, set the 1500 quirks entry to 0x3. 1501 150220160330: 1503 The FAST_DEPEND build option has been removed and its functionality is 1504 now the one true way. The old mkdep(1) style of 'make depend' has 1505 been removed. See 20160311 for further details. 1506 150720160317: 1508 Resource range types have grown from unsigned long to uintmax_t. All 1509 drivers, and anything using libdevinfo, need to be recompiled. 1510 151120160311: 1512 WITH_FAST_DEPEND is now enabled by default for in-tree and out-of-tree 1513 builds. It no longer runs mkdep(1) during 'make depend', and the 1514 'make depend' stage can safely be skipped now as it is auto ran 1515 when building 'make all' and will generate all SRCS and DPSRCS before 1516 building anything else. Dependencies are gathered at compile time with 1517 -MF flags kept in separate .depend files per object file. Users should 1518 run 'make cleandepend' once if using -DNO_CLEAN to clean out older 1519 stale .depend files. 1520 152120160306: 1522 On amd64, clang 3.8.0 can now insert sections of type AMD64_UNWIND into 1523 kernel modules. Therefore, if you load any kernel modules at boot time, 1524 please install the boot loaders after you install the kernel, but before 1525 rebooting, e.g.: 1526 1527 make buildworld 1528 make buildkernel KERNCONF=YOUR_KERNEL_HERE 1529 make installkernel KERNCONF=YOUR_KERNEL_HERE 1530 make -C sys/boot install 1531 <reboot in single user> 1532 1533 Then follow the usual steps, described in the General Notes section, 1534 below. 1535 153620160305: 1537 Clang, llvm, lldb and compiler-rt have been upgraded to 3.8.0. Please 1538 see the 20141231 entry below for information about prerequisites and 1539 upgrading, if you are not already using clang 3.5.0 or higher. 1540 154120160301: 1542 The AIO subsystem is now a standard part of the kernel. The 1543 VFS_AIO kernel option and aio.ko kernel module have been removed. 1544 Due to stability concerns, asynchronous I/O requests are only 1545 permitted on sockets and raw disks by default. To enable 1546 asynchronous I/O requests on all file types, set the 1547 vfs.aio.enable_unsafe sysctl to a non-zero value. 1548 154920160226: 1550 The ELF object manipulation tool objcopy is now provided by the 1551 ELF Tool Chain project rather than by GNU binutils. It should be a 1552 drop-in replacement, with the addition of arm64 support. The 1553 (temporary) src.conf knob WITHOUT_ELFCOPY_AS_OBJCOPY knob may be set 1554 to obtain the GNU version if necessary. 1555 155620160129: 1557 Building ZFS pools on top of zvols is prohibited by default. That 1558 feature has never worked safely; it's always been prone to deadlocks. 1559 Using a zvol as the backing store for a VM guest's virtual disk will 1560 still work, even if the guest is using ZFS. Legacy behavior can be 1561 restored by setting vfs.zfs.vol.recursive=1. 1562 156320160119: 1564 The NONE and HPN patches has been removed from OpenSSH. They are 1565 still available in the security/openssh-portable port. 1566 156720160113: 1568 With the addition of ypldap(8), a new _ypldap user is now required 1569 during installworld. "mergemaster -p" can be used to add the user 1570 prior to installworld, as documented in the handbook. 1571 157220151216: 1573 The tftp loader (pxeboot) now uses the option root-path directive. As a 1574 consequence it no longer looks for a pxeboot.4th file on the tftp 1575 server. Instead it uses the regular /boot infrastructure as with the 1576 other loaders. 1577 157820151211: 1579 The code to start recording plug and play data into the modules has 1580 been committed. While the old tools will properly build a new kernel, 1581 a number of warnings about "unknown metadata record 4" will be produced 1582 for an older kldxref. To avoid such warnings, make sure to rebuild 1583 the kernel toolchain (or world). Make sure that you have r292078 or 1584 later when trying to build 292077 or later before rebuilding. 1585 158620151207: 1587 Debug data files are now built by default with 'make buildworld' and 1588 installed with 'make installworld'. This facilitates debugging but 1589 requires more disk space both during the build and for the installed 1590 world. Debug files may be disabled by setting WITHOUT_DEBUG_FILES=yes 1591 in src.conf(5). 1592 159320151130: 1594 r291527 changed the internal interface between the nfsd.ko and 1595 nfscommon.ko modules. As such, they must both be upgraded to-gether. 1596 __FreeBSD_version has been bumped because of this. 1597 159820151108: 1599 Add support for unicode collation strings leads to a change of 1600 order of files listed by ls(1) for example. To get back to the old 1601 behaviour, set LC_COLLATE environment variable to "C". 1602 1603 Databases administrators will need to reindex their databases given 1604 collation results will be different. 1605 1606 Due to a bug in install(1) it is recommended to remove the ancient 1607 locales before running make installworld. 1608 1609 rm -rf /usr/share/locale/* 1610 161120151030: 1612 The OpenSSL has been upgraded to 1.0.2d. Any binaries requiring 1613 libcrypto.so.7 or libssl.so.7 must be recompiled. 1614 161520151020: 1616 Qlogic 24xx/25xx firmware images were updated from 5.5.0 to 7.3.0. 1617 Kernel modules isp_2400_multi and isp_2500_multi were removed and 1618 should be replaced with isp_2400 and isp_2500 modules respectively. 1619 162020151017: 1621 The build previously allowed using 'make -n' to not recurse into 1622 sub-directories while showing what commands would be executed, and 1623 'make -n -n' to recursively show commands. Now 'make -n' will recurse 1624 and 'make -N' will not. 1625 162620151012: 1627 If you specify SENDMAIL_MC or SENDMAIL_CF in make.conf, mergemaster 1628 and etcupdate will now use this file. A custom sendmail.cf is now 1629 updated via this mechanism rather than via installworld. If you had 1630 excluded sendmail.cf in mergemaster.rc or etcupdate.conf, you may 1631 want to remove the exclusion or change it to "always install". 1632 /etc/mail/sendmail.cf is now managed the same way regardless of 1633 whether SENDMAIL_MC/SENDMAIL_CF is used. If you are not using 1634 SENDMAIL_MC/SENDMAIL_CF there should be no change in behavior. 1635 163620151011: 1637 Compatibility shims for legacy ATA device names have been removed. 1638 It includes ATA_STATIC_ID kernel option, kern.cam.ada.legacy_aliases 1639 and kern.geom.raid.legacy_aliases loader tunables, kern.devalias.* 1640 environment variables, /dev/ad* and /dev/ar* symbolic links. 1641 164220151006: 1643 Clang, llvm, lldb, compiler-rt and libc++ have been upgraded to 3.7.0. 1644 Please see the 20141231 entry below for information about prerequisites 1645 and upgrading, if you are not already using clang 3.5.0 or higher. 1646 164720150924: 1648 Kernel debug files have been moved to /usr/lib/debug/boot/kernel/, 1649 and renamed from .symbols to .debug. This reduces the size requirements 1650 on the boot partition or file system and provides consistency with 1651 userland debug files. 1652 1653 When using the supported kernel installation method the 1654 /usr/lib/debug/boot/kernel directory will be renamed (to kernel.old) 1655 as is done with /boot/kernel. 1656 1657 Developers wishing to maintain the historical behavior of installing 1658 debug files in /boot/kernel/ can set KERN_DEBUGDIR="" in src.conf(5). 1659 166020150827: 1661 The wireless drivers had undergone changes that remove the 'parent 1662 interface' from the ifconfig -l output. The rc.d network scripts 1663 used to check presence of a parent interface in the list, so old 1664 scripts would fail to start wireless networking. Thus, etcupdate(3) 1665 or mergemaster(8) run is required after kernel update, to update your 1666 rc.d scripts in /etc. 1667 166820150827: 1669 pf no longer supports 'scrub fragment crop' or 'scrub fragment drop-ovl' 1670 These configurations are now automatically interpreted as 1671 'scrub fragment reassemble'. 1672 167320150817: 1674 Kernel-loadable modules for the random(4) device are back. To use 1675 them, the kernel must have 1676 1677 device random 1678 options RANDOM_LOADABLE 1679 1680 kldload(8) can then be used to load random_fortuna.ko 1681 or random_yarrow.ko. Please note that due to the indirect 1682 function calls that the loadable modules need to provide, 1683 the build-in variants will be slightly more efficient. 1684 1685 The random(4) kernel option RANDOM_DUMMY has been retired due to 1686 unpopularity. It was not all that useful anyway. 1687 168820150813: 1689 The WITHOUT_ELFTOOLCHAIN_TOOLS src.conf(5) knob has been retired. 1690 Control over building the ELF Tool Chain tools is now provided by 1691 the WITHOUT_TOOLCHAIN knob. 1692 169320150810: 1694 The polarity of Pulse Per Second (PPS) capture events with the 1695 uart(4) driver has been corrected. Prior to this change the PPS 1696 "assert" event corresponded to the trailing edge of a positive PPS 1697 pulse and the "clear" event was the leading edge of the next pulse. 1698 1699 As the width of a PPS pulse in a typical GPS receiver is on the 1700 order of 1 millisecond, most users will not notice any significant 1701 difference with this change. 1702 1703 Anyone who has compensated for the historical polarity reversal by 1704 configuring a negative offset equal to the pulse width will need to 1705 remove that workaround. 1706 170720150809: 1708 The default group assigned to /dev/dri entries has been changed 1709 from 'wheel' to 'video' with the id of '44'. If you want to have 1710 access to the dri devices please add yourself to the video group 1711 with: 1712 1713 # pw groupmod video -m $USER 1714 171520150806: 1716 The menu.rc and loader.rc files will now be replaced during 1717 upgrades. Please migrate local changes to menu.rc.local and 1718 loader.rc.local instead. 1719 172020150805: 1721 GNU Binutils versions of addr2line, c++filt, nm, readelf, size, 1722 strings and strip have been removed. The src.conf(5) knob 1723 WITHOUT_ELFTOOLCHAIN_TOOLS no longer provides the binutils tools. 1724 172520150728: 1726 As ZFS requires more kernel stack pages than is the default on some 1727 architectures e.g. i386, it now warns if KSTACK_PAGES is less than 1728 ZFS_MIN_KSTACK_PAGES (which is 4 at the time of writing). 1729 1730 Please consider using 'options KSTACK_PAGES=X' where X is greater 1731 than or equal to ZFS_MIN_KSTACK_PAGES i.e. 4 in such configurations. 1732 173320150706: 1734 sendmail has been updated to 8.15.2. Starting with FreeBSD 11.0 1735 and sendmail 8.15, sendmail uses uncompressed IPv6 addresses by 1736 default, i.e., they will not contain "::". For example, instead 1737 of ::1, it will be 0:0:0:0:0:0:0:1. This permits a zero subnet 1738 to have a more specific match, such as different map entries for 1739 IPv6:0:0 vs IPv6:0. This change requires that configuration 1740 data (including maps, files, classes, custom ruleset, etc.) must 1741 use the same format, so make certain such configuration data is 1742 upgrading. As a very simple check search for patterns like 1743 'IPv6:[0-9a-fA-F:]*::' and 'IPv6::'. To return to the old 1744 behavior, set the m4 option confUSE_COMPRESSED_IPV6_ADDRESSES or 1745 the cf option UseCompressedIPv6Addresses. 1746 174720150630: 1748 The default kernel entropy-processing algorithm is now 1749 Fortuna, replacing Yarrow. 1750 1751 Assuming you have 'device random' in your kernel config 1752 file, the configurations allow a kernel option to override 1753 this default. You may choose *ONE* of: 1754 1755 options RANDOM_YARROW # Legacy /dev/random algorithm. 1756 options RANDOM_DUMMY # Blocking-only driver. 1757 1758 If you have neither, you get Fortuna. For most people, 1759 read no further, Fortuna will give a /dev/random that works 1760 like it always used to, and the difference will be irrelevant. 1761 1762 If you remove 'device random', you get *NO* kernel-processed 1763 entropy at all. This may be acceptable to folks building 1764 embedded systems, but has complications. Carry on reading, 1765 and it is assumed you know what you need. 1766 1767 *PLEASE* read random(4) and random(9) if you are in the 1768 habit of tweaking kernel configs, and/or if you are a member 1769 of the embedded community, wanting specific and not-usual 1770 behaviour from your security subsystems. 1771 1772 NOTE!! If you use RANDOM_DUMMY and/or have no 'device 1773 random', you will NOT have a functioning /dev/random, and 1774 many cryptographic features will not work, including SSH. 1775 You may also find strange behaviour from the random(3) set 1776 of library functions, in particular sranddev(3), srandomdev(3) 1777 and arc4random(3). The reason for this is that the KERN_ARND 1778 sysctl only returns entropy if it thinks it has some to 1779 share, and with RANDOM_DUMMY or no 'device random' this 1780 will never happen. 1781 178220150623: 1783 An additional fix for the issue described in the 20150614 sendmail 1784 entry below has been committed in revision 284717. 1785 178620150616: 1787 FreeBSD's old make (fmake) has been removed from the system. It is 1788 available as the devel/fmake port or via pkg install fmake. 1789 179020150615: 1791 The fix for the issue described in the 20150614 sendmail entry 1792 below has been committed in revision 284436. The work 1793 around described in that entry is no longer needed unless the 1794 default setting is overridden by a confDH_PARAMETERS configuration 1795 setting of '5' or pointing to a 512 bit DH parameter file. 1796 179720150614: 1798 ALLOW_DEPRECATED_ATF_TOOLS/ATFFILE support has been removed from 1799 atf.test.mk (included from bsd.test.mk). Please upgrade devel/atf 1800 and devel/kyua to version 0.20+ and adjust any calling code to work 1801 with Kyuafile and kyua. 1802 180320150614: 1804 The import of openssl to address the FreeBSD-SA-15:10.openssl 1805 security advisory includes a change which rejects handshakes 1806 with DH parameters below 768 bits. sendmail releases prior 1807 to 8.15.2 (not yet released), defaulted to a 512 bit 1808 DH parameter setting for client connections. To work around 1809 this interoperability, sendmail can be configured to use a 1810 2048 bit DH parameter by: 1811 1812 1. Edit /etc/mail/`hostname`.mc 1813 2. If a setting for confDH_PARAMETERS does not exist or 1814 exists and is set to a string beginning with '5', 1815 replace it with '2'. 1816 3. If a setting for confDH_PARAMETERS exists and is set to 1817 a file path, create a new file with: 1818 openssl dhparam -out /path/to/file 2048 1819 4. Rebuild the .cf file: 1820 cd /etc/mail/; make; make install 1821 5. Restart sendmail: 1822 cd /etc/mail/; make restart 1823 1824 A sendmail patch is coming, at which time this file will be 1825 updated. 1826 182720150604: 1828 Generation of legacy formatted entries have been disabled by default 1829 in pwd_mkdb(8), as all base system consumers of the legacy formatted 1830 entries were converted to use the new format by default when the new, 1831 machine independent format have been added and supported since FreeBSD 1832 5.x. 1833 1834 Please see the pwd_mkdb(8) manual page for further details. 1835 183620150525: 1837 Clang and llvm have been upgraded to 3.6.1 release. Please see the 1838 20141231 entry below for information about prerequisites and upgrading, 1839 if you are not already using 3.5.0 or higher. 1840 184120150521: 1842 TI platform code switched to using vendor DTS files and this update 1843 may break existing systems running on Beaglebone, Beaglebone Black, 1844 and Pandaboard: 1845 1846 - dtb files should be regenerated/reinstalled. Filenames are the 1847 same but content is different now 1848 - GPIO addressing was changed, now each GPIO bank (32 pins per bank) 1849 has its own /dev/gpiocX device, e.g. pin 121 on /dev/gpioc0 in old 1850 addressing scheme is now pin 25 on /dev/gpioc3. 1851 - Pandaboard: /etc/ttys should be updated, serial console device is 1852 now /dev/ttyu2, not /dev/ttyu0 1853 185420150501: 1855 soelim(1) from gnu/usr.bin/groff has been replaced by usr.bin/soelim. 1856 If you need the GNU extension from groff soelim(1), install groff 1857 from package: pkg install groff, or via ports: textproc/groff. 1858 185920150423: 1860 chmod, chflags, chown and chgrp now affect symlinks in -R mode as 1861 defined in symlink(7); previously symlinks were silently ignored. 1862 186320150415: 1864 The const qualifier has been removed from iconv(3) to comply with 1865 POSIX. The ports tree is aware of this from r384038 onwards. 1866 186720150416: 1868 Libraries specified by LIBADD in Makefiles must have a corresponding 1869 DPADD_<lib> variable to ensure correct dependencies. This is now 1870 enforced in src.libnames.mk. 1871 187220150324: 1873 From legacy ata(4) driver was removed support for SATA controllers 1874 supported by more functional drivers ahci(4), siis(4) and mvs(4). 1875 Kernel modules ataahci and ataadaptec were removed completely, 1876 replaced by ahci and mvs modules respectively. 1877 187820150315: 1879 Clang, llvm and lldb have been upgraded to 3.6.0 release. Please see 1880 the 20141231 entry below for information about prerequisites and 1881 upgrading, if you are not already using 3.5.0 or higher. 1882 188320150307: 1884 The 32-bit PowerPC kernel has been changed to a position-independent 1885 executable. This can only be booted with a version of loader(8) 1886 newer than January 31, 2015, so make sure to update both world and 1887 kernel before rebooting. 1888 188920150217: 1890 If you are running a -CURRENT kernel since r273872 (Oct 30th, 2014), 1891 but before r278950, the RNG was not seeded properly. Immediately 1892 upgrade the kernel to r278950 or later and regenerate any keys (e.g. 1893 ssh keys or openssl keys) that were generated w/ a kernel from that 1894 range. This does not affect programs that directly used /dev/random 1895 or /dev/urandom. All userland uses of arc4random(3) are affected. 1896 189720150210: 1898 The autofs(4) ABI was changed in order to restore binary compatibility 1899 with 10.1-RELEASE. The automountd(8) daemon needs to be rebuilt to work 1900 with the new kernel. 1901 190220150131: 1903 The powerpc64 kernel has been changed to a position-independent 1904 executable. This can only be booted with a new version of loader(8), 1905 so make sure to update both world and kernel before rebooting. 1906 190720150118: 1908 Clang and llvm have been upgraded to 3.5.1 release. This is a bugfix 1909 only release, no new features have been added. Please see the 20141231 1910 entry below for information about prerequisites and upgrading, if you 1911 are not already using 3.5.0. 1912 191320150107: 1914 ELF tools addr2line, elfcopy (strip), nm, size, and strings are now 1915 taken from the ELF Tool Chain project rather than GNU binutils. They 1916 should be drop-in replacements, with the addition of arm64 support. 1917 The WITHOUT_ELFTOOLCHAIN_TOOLS= knob may be used to obtain the 1918 binutils tools, if necessary. See 20150805 for updated information. 1919 192020150105: 1921 The default Unbound configuration now enables remote control 1922 using a local socket. Users who have already enabled the 1923 local_unbound service should regenerate their configuration 1924 by running "service local_unbound setup" as root. 1925 192620150102: 1927 The GNU texinfo and GNU info pages have been removed. 1928 To be able to view GNU info pages please install texinfo from ports. 1929 193020141231: 1931 Clang, llvm and lldb have been upgraded to 3.5.0 release. 1932 1933 As of this release, a prerequisite for building clang, llvm and lldb is 1934 a C++11 capable compiler and C++11 standard library. This means that to 1935 be able to successfully build the cross-tools stage of buildworld, with 1936 clang as the bootstrap compiler, your system compiler or cross compiler 1937 should either be clang 3.3 or later, or gcc 4.8 or later, and your 1938 system C++ library should be libc++, or libdstdc++ from gcc 4.8 or 1939 later. 1940 1941 On any standard FreeBSD 10.x or 11.x installation, where clang and 1942 libc++ are on by default (that is, on x86 or arm), this should work out 1943 of the box. 1944 1945 On 9.x installations where clang is enabled by default, e.g. on x86 and 1946 powerpc, libc++ will not be enabled by default, so libc++ should be 1947 built (with clang) and installed first. If both clang and libc++ are 1948 missing, build clang first, then use it to build libc++. 1949 1950 On 8.x and earlier installations, upgrade to 9.x first, and then follow 1951 the instructions for 9.x above. 1952 1953 Sparc64 and mips users are unaffected, as they still use gcc 4.2.1 by 1954 default, and do not build clang. 1955 1956 Many embedded systems are resource constrained, and will not be able to 1957 build clang in a reasonable time, or in some cases at all. In those 1958 cases, cross building bootable systems on amd64 is a workaround. 1959 1960 This new version of clang introduces a number of new warnings, of which 1961 the following are most likely to appear: 1962 1963 -Wabsolute-value 1964 1965 This warns in two cases, for both C and C++: 1966 * When the code is trying to take the absolute value of an unsigned 1967 quantity, which is effectively a no-op, and almost never what was 1968 intended. The code should be fixed, if at all possible. If you are 1969 sure that the unsigned quantity can be safely cast to signed, without 1970 loss of information or undefined behavior, you can add an explicit 1971 cast, or disable the warning. 1972 1973 * When the code is trying to take an absolute value, but the called 1974 abs() variant is for the wrong type, which can lead to truncation. 1975 If you want to disable the warning instead of fixing the code, please 1976 make sure that truncation will not occur, or it might lead to unwanted 1977 side-effects. 1978 1979 -Wtautological-undefined-compare and 1980 -Wundefined-bool-conversion 1981 1982 These warn when C++ code is trying to compare 'this' against NULL, while 1983 'this' should never be NULL in well-defined C++ code. However, there is 1984 some legacy (pre C++11) code out there, which actively abuses this 1985 feature, which was less strictly defined in previous C++ versions. 1986 1987 Squid and openjdk do this, for example. The warning can be turned off 1988 for C++98 and earlier, but compiling the code in C++11 mode might result 1989 in unexpected behavior; for example, the parts of the program that are 1990 unreachable could be optimized away. 1991 199220141222: 1993 The old NFS client and server (kernel options NFSCLIENT, NFSSERVER) 1994 kernel sources have been removed. The .h files remain, since some 1995 utilities include them. This will need to be fixed later. 1996 If "mount -t oldnfs ..." is attempted, it will fail. 1997 If the "-o" option on mountd(8), nfsd(8) or nfsstat(1) is used, 1998 the utilities will report errors. 1999 200020141121: 2001 The handling of LOCAL_LIB_DIRS has been altered to skip addition of 2002 directories to top level SUBDIR variable when their parent 2003 directory is included in LOCAL_DIRS. Users with build systems with 2004 such hierarchies and without SUBDIR entries in the parent 2005 directory Makefiles should add them or add the directories to 2006 LOCAL_DIRS. 2007 200820141109: 2009 faith(4) and faithd(8) have been removed from the base system. Faith 2010 has been obsolete for a very long time. 2011 201220141104: 2013 vt(4), the new console driver, is enabled by default. It brings 2014 support for Unicode and double-width characters, as well as 2015 support for UEFI and integration with the KMS kernel video 2016 drivers. 2017 2018 You may need to update your console settings in /etc/rc.conf, 2019 most probably the keymap. During boot, /etc/rc.d/syscons will 2020 indicate what you need to do. 2021 2022 vt(4) still has issues and lacks some features compared to 2023 syscons(4). See the wiki for up-to-date information: 2024 https://wiki.freebsd.org/Newcons 2025 2026 If you want to keep using syscons(4), you can do so by adding 2027 the following line to /boot/loader.conf: 2028 kern.vty=sc 2029 203020141102: 2031 pjdfstest has been integrated into kyua as an opt-in test suite. 2032 Please see share/doc/pjdfstest/README for more details on how to 2033 execute it. 2034 203520141009: 2036 gperf has been removed from the base system for architectures 2037 that use clang. Ports that require gperf will obtain it from the 2038 devel/gperf port. 2039 204020140923: 2041 pjdfstest has been moved from tools/regression/pjdfstest to 2042 contrib/pjdfstest . 2043 204420140922: 2045 At svn r271982, The default linux compat kernel ABI has been adjusted 2046 to 2.6.18 in support of the linux-c6 compat ports infrastructure 2047 update. If you wish to continue using the linux-f10 compat ports, 2048 add compat.linux.osrelease=2.6.16 to your local sysctl.conf. Users are 2049 encouraged to update their linux-compat packages to linux-c6 during 2050 their next update cycle. 2051 205220140729: 2053 The ofwfb driver, used to provide a graphics console on PowerPC when 2054 using vt(4), no longer allows mmap() of all physical memory. This 2055 will prevent Xorg on PowerPC with some ATI graphics cards from 2056 initializing properly unless x11-servers/xorg-server is updated to 2057 1.12.4_8 or newer. 2058 205920140723: 2060 The xdev targets have been converted to using TARGET and 2061 TARGET_ARCH instead of XDEV and XDEV_ARCH. 2062 206320140719: 2064 The default unbound configuration has been modified to address 2065 issues with reverse lookups on networks that use private 2066 address ranges. If you use the local_unbound service, run 2067 "service local_unbound setup" as root to regenerate your 2068 configuration, then "service local_unbound reload" to load the 2069 new configuration. 2070 207120140709: 2072 The GNU texinfo and GNU info pages are not built and installed 2073 anymore, WITH_INFO knob has been added to allow to built and install 2074 them again. 2075 UPDATE: see 20150102 entry on texinfo's removal 2076 207720140708: 2078 The GNU readline library is now an INTERNALLIB - that is, it is 2079 statically linked into consumers (GDB and variants) in the base 2080 system, and the shared library is no longer installed. The 2081 devel/readline port is available for third party software that 2082 requires readline. 2083 208420140702: 2085 The Itanium architecture (ia64) has been removed from the list of 2086 known architectures. This is the first step in the removal of the 2087 architecture. 2088 208920140701: 2090 Commit r268115 has added NFSv4.1 server support, merged from 2091 projects/nfsv4.1-server. Since this includes changes to the 2092 internal interfaces between the NFS related modules, a full 2093 build of the kernel and modules will be necessary. 2094 __FreeBSD_version has been bumped. 2095 209620140629: 2097 The WITHOUT_VT_SUPPORT kernel config knob has been renamed 2098 WITHOUT_VT. (The other _SUPPORT knobs have a consistent meaning 2099 which differs from the behaviour controlled by this knob.) 2100 210120140619: 2102 Maximal length of the serial number in CTL was increased from 16 to 2103 64 chars, that breaks ABI. All CTL-related tools, such as ctladm 2104 and ctld, need to be rebuilt to work with a new kernel. 2105 210620140606: 2107 The libatf-c and libatf-c++ major versions were downgraded to 0 and 2108 1 respectively to match the upstream numbers. They were out of 2109 sync because, when they were originally added to FreeBSD, the 2110 upstream versions were not respected. These libraries are private 2111 and not yet built by default, so renumbering them should be a 2112 non-issue. However, unclean source trees will yield broken test 2113 programs once the operator executes "make delete-old-libs" after a 2114 "make installworld". 2115 2116 Additionally, the atf-sh binary was made private by moving it into 2117 /usr/libexec/. Already-built shell test programs will keep the 2118 path to the old binary so they will break after "make delete-old" 2119 is run. 2120 2121 If you are using WITH_TESTS=yes (not the default), wipe the object 2122 tree and rebuild from scratch to prevent spurious test failures. 2123 This is only needed once: the misnumbered libraries and misplaced 2124 binaries have been added to OptionalObsoleteFiles.inc so they will 2125 be removed during a clean upgrade. 2126 212720140512: 2128 Clang and llvm have been upgraded to 3.4.1 release. 2129 213020140508: 2131 We bogusly installed src.opts.mk in /usr/share/mk. This file should 2132 be removed to avoid issues in the future (and has been added to 2133 ObsoleteFiles.inc). 2134 213520140505: 2136 /etc/src.conf now affects only builds of the FreeBSD src tree. In the 2137 past, it affected all builds that used the bsd.*.mk files. The old 2138 behavior was a bug, but people may have relied upon it. To get this 2139 behavior back, you can .include /etc/src.conf from /etc/make.conf 2140 (which is still global and isn't changed). This also changes the 2141 behavior of incremental builds inside the tree of individual 2142 directories. Set MAKESYSPATH to ".../share/mk" to do that. 2143 Although this has survived make universe and some upgrade scenarios, 2144 other upgrade scenarios may have broken. At least one form of 2145 temporary breakage was fixed with MAKESYSPATH settings for buildworld 2146 as well... In cases where MAKESYSPATH isn't working with this 2147 setting, you'll need to set it to the full path to your tree. 2148 2149 One side effect of all this cleaning up is that bsd.compiler.mk 2150 is no longer implicitly included by bsd.own.mk. If you wish to 2151 use COMPILER_TYPE, you must now explicitly include bsd.compiler.mk 2152 as well. 2153 215420140430: 2155 The lindev device has been removed since /dev/full has been made a 2156 standard device. __FreeBSD_version has been bumped. 2157 215820140424: 2159 The knob WITHOUT_VI was added to the base system, which controls 2160 building ex(1), vi(1), etc. Older releases of FreeBSD required ex(1) 2161 in order to reorder files share/termcap and didn't build ex(1) as a 2162 build tool, so building/installing with WITH_VI is highly advised for 2163 build hosts for older releases. 2164 2165 This issue has been fixed in stable/9 and stable/10 in r277022 and 2166 r276991, respectively. 2167 216820140418: 2169 The YES_HESIOD knob has been removed. It has been obsolete for 2170 a decade. Please move to using WITH_HESIOD instead or your builds 2171 will silently lack HESIOD. 2172 217320140405: 2174 The uart(4) driver has been changed with respect to its handling 2175 of the low-level console. Previously the uart(4) driver prevented 2176 any process from changing the baudrate or the CLOCAL and HUPCL 2177 control flags. By removing the restrictions, operators can make 2178 changes to the serial console port without having to reboot. 2179 However, when getty(8) is started on the serial device that is 2180 associated with the low-level console, a misconfigured terminal 2181 line in /etc/ttys will now have a real impact. 2182 Before upgrading the kernel, make sure that /etc/ttys has the 2183 serial console device configured as 3wire without baudrate to 2184 preserve the previous behaviour. E.g: 2185 ttyu0 "/usr/libexec/getty 3wire" vt100 on secure 2186 218720140306: 2188 Support for libwrap (TCP wrappers) in rpcbind was disabled by default 2189 to improve performance. To re-enable it, if needed, run rpcbind 2190 with command line option -W. 2191 219220140226: 2193 Switched back to the GPL dtc compiler due to updates in the upstream 2194 dts files not being supported by the BSDL dtc compiler. You will need 2195 to rebuild your kernel toolchain to pick up the new compiler. Core dumps 2196 may result while building dtb files during a kernel build if you fail 2197 to do so. Set WITHOUT_GPL_DTC if you require the BSDL compiler. 2198 219920140216: 2200 Clang and llvm have been upgraded to 3.4 release. 2201 220220140216: 2203 The nve(4) driver has been removed. Please use the nfe(4) driver 2204 for NVIDIA nForce MCP Ethernet adapters instead. 2205 220620140212: 2207 An ABI incompatibility crept into the libc++ 3.4 import in r261283. 2208 This could cause certain C++ applications using shared libraries built 2209 against the previous version of libc++ to crash. The incompatibility 2210 has now been fixed, but any C++ applications or shared libraries built 2211 between r261283 and r261801 should be recompiled. 2212 221320140204: 2214 OpenSSH will now ignore errors caused by kernel lacking of Capsicum 2215 capability mode support. Please note that enabling the feature in 2216 kernel is still highly recommended. 2217 221820140131: 2219 OpenSSH is now built with sandbox support, and will use sandbox as 2220 the default privilege separation method. This requires Capsicum 2221 capability mode support in kernel. 2222 222320140128: 2224 The libelf and libdwarf libraries have been updated to newer 2225 versions from upstream. Shared library version numbers for 2226 these two libraries were bumped. Any ports or binaries 2227 requiring these two libraries should be recompiled. 2228 __FreeBSD_version is bumped to 1100006. 2229 223020140110: 2231 If a Makefile in a tests/ directory was auto-generating a Kyuafile 2232 instead of providing an explicit one, this would prevent such 2233 Makefile from providing its own Kyuafile in the future during 2234 NO_CLEAN builds. This has been fixed in the Makefiles but manual 2235 intervention is needed to clean an objdir if you use NO_CLEAN: 2236 # find /usr/obj -name Kyuafile | xargs rm -f 2237 223820131213: 2239 The behavior of gss_pseudo_random() for the krb5 mechanism 2240 has changed, for applications requesting a longer random string 2241 than produced by the underlying enctype's pseudo-random() function. 2242 In particular, the random string produced from a session key of 2243 enctype aes256-cts-hmac-sha1-96 or aes256-cts-hmac-sha1-96 will 2244 be different at the 17th octet and later, after this change. 2245 The counter used in the PRF+ construction is now encoded as a 2246 big-endian integer in accordance with RFC 4402. 2247 __FreeBSD_version is bumped to 1100004. 2248 224920131108: 2250 The WITHOUT_ATF build knob has been removed and its functionality 2251 has been subsumed into the more generic WITHOUT_TESTS. If you were 2252 using the former to disable the build of the ATF libraries, you 2253 should change your settings to use the latter. 2254 225520131025: 2256 The default version of mtree is nmtree which is obtained from 2257 NetBSD. The output is generally the same, but may vary 2258 slightly. If you found you need identical output adding 2259 "-F freebsd9" to the command line should do the trick. For the 2260 time being, the old mtree is available as fmtree. 2261 226220131014: 2263 libbsdyml has been renamed to libyaml and moved to /usr/lib/private. 2264 This will break ports-mgmt/pkg. Rebuild the port, or upgrade to pkg 2265 1.1.4_8 and verify bsdyml not linked in, before running "make 2266 delete-old-libs": 2267 # make -C /usr/ports/ports-mgmt/pkg build deinstall install clean 2268 or 2269 # pkg install pkg; ldd /usr/local/sbin/pkg | grep bsdyml 2270 227120131010: 2272 The stable/10 branch has been created in subversion from head 2273 revision r256279. 2274 2275COMMON ITEMS: 2276 2277 General Notes 2278 ------------- 2279 Sometimes, obscure build problems are the result of environment 2280 poisoning. This can happen because the make utility reads its 2281 environment when searching for values for global variables. To run 2282 your build attempts in an "environmental clean room", prefix all make 2283 commands with 'env -i '. See the env(1) manual page for more details. 2284 Occasionally a build failure will occur with "make -j" due to a race 2285 condition. If this happens try building again without -j, and please 2286 report a bug if it happens consistently. 2287 2288 When upgrading from one major version to another it is generally best to 2289 upgrade to the latest code in the currently installed branch first, then 2290 do an upgrade to the new branch. This is the best-tested upgrade path, 2291 and has the highest probability of being successful. Please try this 2292 approach if you encounter problems with a major version upgrade. Since 2293 the stable 4.x branch point, one has generally been able to upgrade from 2294 anywhere in the most recent stable branch to head / current (or even the 2295 last couple of stable branches). See the top of this file when there's 2296 an exception. 2297 2298 The update process will emit an error on an attempt to perform a build 2299 or install from a FreeBSD version below the earliest supported version. 2300 When updating from an older version the update should be performed one 2301 major release at a time, including running `make delete-old` at each 2302 step. 2303 2304 When upgrading a live system, having a root shell around before 2305 installing anything can help undo problems. Not having a root shell 2306 around can lead to problems if pam has changed too much from your 2307 starting point to allow continued authentication after the upgrade. 2308 2309 This file should be read as a log of events. When a later event changes 2310 information of a prior event, the prior event should not be deleted. 2311 Instead, a pointer to the entry with the new information should be 2312 placed in the old entry. Readers of this file should also sanity check 2313 older entries before relying on them blindly. Authors of new entries 2314 should write them with this in mind. 2315 2316 ZFS notes 2317 --------- 2318 When upgrading the boot ZFS pool to a new version, always follow 2319 these two steps: 2320 2321 1.) recompile and reinstall the ZFS boot loader and boot block 2322 (this is part of "make buildworld" and "make installworld") 2323 2324 2.) update the ZFS boot block on your boot drive 2325 2326 The following example updates the ZFS boot block on the 2327 freebsd-boot partition of a GPT partitioned drive ada0: 2328 "gpart bootcode -p /boot/gptzfsboot -i $N ada0" 2329 The value $N will typically be 1 (if booting from BIOS) or 2 (if 2330 booting from EFI). 2331 2332 Non-boot pools do not need these updates. 2333 2334 To build a kernel 2335 ----------------- 2336 If you are updating from a prior version of FreeBSD (even one just 2337 a few days old), you should follow this procedure. It is the most 2338 failsafe as it uses a /usr/obj tree with a fresh mini-buildworld, 2339 2340 make kernel-toolchain 2341 make -DALWAYS_CHECK_MAKE buildkernel KERNCONF=YOUR_KERNEL_HERE 2342 make -DALWAYS_CHECK_MAKE installkernel KERNCONF=YOUR_KERNEL_HERE 2343 2344 To test a kernel once 2345 --------------------- 2346 If you just want to boot a kernel once (because you are not sure 2347 if it works, or if you want to boot a known bad kernel to provide 2348 debugging information) run 2349 make installkernel KERNCONF=YOUR_KERNEL_HERE KODIR=/boot/testkernel 2350 nextboot -k testkernel 2351 2352 To rebuild everything and install it on the current system. 2353 ----------------------------------------------------------- 2354 # Note: sometimes if you are running current you gotta do more than 2355 # is listed here if you are upgrading from a really old current. 2356 2357 <make sure you have good level 0 dumps> 2358 make buildworld 2359 make buildkernel KERNCONF=YOUR_KERNEL_HERE 2360 make installkernel KERNCONF=YOUR_KERNEL_HERE 2361 [1] 2362 <reboot in single user> [3] 2363 mergemaster -Fp [5] 2364 make installworld 2365 mergemaster -Fi [4] 2366 make delete-old [6] 2367 <reboot> 2368 2369 To cross-install current onto a separate partition 2370 -------------------------------------------------- 2371 # In this approach we use a separate partition to hold 2372 # current's root, 'usr', and 'var' directories. A partition 2373 # holding "/", "/usr" and "/var" should be about 2GB in 2374 # size. 2375 2376 <make sure you have good level 0 dumps> 2377 <boot into -stable> 2378 make buildworld 2379 make buildkernel KERNCONF=YOUR_KERNEL_HERE 2380 <maybe newfs current's root partition> 2381 <mount current's root partition on directory ${CURRENT_ROOT}> 2382 make installworld DESTDIR=${CURRENT_ROOT} -DDB_FROM_SRC 2383 make distribution DESTDIR=${CURRENT_ROOT} # if newfs'd 2384 make installkernel KERNCONF=YOUR_KERNEL_HERE DESTDIR=${CURRENT_ROOT} 2385 cp /etc/fstab ${CURRENT_ROOT}/etc/fstab # if newfs'd 2386 <edit ${CURRENT_ROOT}/etc/fstab to mount "/" from the correct partition> 2387 <reboot into current> 2388 <do a "native" rebuild/install as described in the previous section> 2389 <maybe install compatibility libraries from ports/misc/compat*> 2390 <reboot> 2391 2392 2393 To upgrade in-place from stable to current 2394 ---------------------------------------------- 2395 <make sure you have good level 0 dumps> 2396 make buildworld [9] 2397 make buildkernel KERNCONF=YOUR_KERNEL_HERE [8] 2398 make installkernel KERNCONF=YOUR_KERNEL_HERE 2399 [1] 2400 <reboot in single user> [3] 2401 mergemaster -Fp [5] 2402 make installworld 2403 mergemaster -Fi [4] 2404 make delete-old [6] 2405 <reboot> 2406 2407 Make sure that you've read the UPDATING file to understand the 2408 tweaks to various things you need. At this point in the life 2409 cycle of current, things change often and you are on your own 2410 to cope. The defaults can also change, so please read ALL of 2411 the UPDATING entries. 2412 2413 Also, if you are tracking -current, you must be subscribed to 2414 [email protected]. Make sure that before you update 2415 your sources that you have read and understood all the recent 2416 messages there. If in doubt, please track -stable which has 2417 much fewer pitfalls. 2418 2419 [1] If you have third party modules, such as vmware, you should disable 2420 them at this point so they don't crash your system on 2421 reboot. Alternatively, you should rebuild all the modules you have in 2422 your system and install them as well. If you are running -current, you 2423 should seriously consider placing all sources to all the modules for 2424 your system (or symlinks to them) in /usr/local/sys/modules so this 2425 happens automatically. If all your modules come from ports, then adding 2426 the port origin directories to PORTS_MODULES instead is also automatic 2427 and effective, eg: 2428 PORTS_MODULES+=x11/nvidia-driver 2429 2430 [3] From the bootblocks, boot -s, and then do 2431 fsck -p 2432 mount -u / 2433 mount -a 2434 sh /etc/rc.d/zfs start # mount zfs filesystem, if needed 2435 cd src # full path to source 2436 adjkerntz -i # if CMOS is wall time 2437 Also, when doing a major release upgrade, it is required that you boot 2438 into single user mode to do the installworld. 2439 2440 [4] Note: This step is non-optional. Failure to do this step 2441 can result in a significant reduction in the functionality of the 2442 system. Attempting to do it by hand is not recommended and those 2443 that pursue this avenue should read this file carefully, as well 2444 as the archives of freebsd-current and freebsd-hackers mailing lists 2445 for potential gotchas. The -U option is also useful to consider. 2446 See mergemaster(8) for more information. 2447 2448 [5] Usually this step is a no-op. However, from time to time 2449 you may need to do this if you get unknown user in the following 2450 step. It never hurts to do it all the time. You may need to 2451 install a new mergemaster (cd src/usr.sbin/mergemaster && make 2452 install) after the buildworld before this step if you last updated 2453 from current before 20130425 or from -stable before 20130430. 2454 2455 [6] This only deletes old files and directories. Old libraries 2456 can be deleted by "make delete-old-libs", but you have to make 2457 sure that no program is using those libraries anymore. 2458 2459 [8] The new kernel must be able to run existing binaries used by an 2460 installworld. When upgrading across major versions, the new kernel's 2461 configuration must include the correct COMPAT_FREEBSD<n> option for 2462 existing binaries (e.g. COMPAT_FREEBSD11 to run 11.x binaries). Failure 2463 to do so may leave you with a system that is hard to boot to recover. A 2464 GENERIC kernel will include suitable compatibility options to run 2465 binaries from older branches. Note that the ability to run binaries 2466 from unsupported branches is not guaranteed. 2467 2468 Make sure that you merge any new devices from GENERIC since the 2469 last time you updated your kernel config file. Options also 2470 change over time, so you may need to adjust your custom kernels 2471 for these as well. 2472 2473 [9] If CPUTYPE is defined in your /etc/make.conf, make sure to use the 2474 "?=" instead of the "=" assignment operator, so that buildworld can 2475 override the CPUTYPE if it needs to. 2476 2477 MAKEOBJDIRPREFIX must be defined in an environment variable, and 2478 not on the command line, or in /etc/make.conf. buildworld will 2479 warn if it is improperly defined. 2480FORMAT: 2481 2482This file contains a list, in reverse chronological order, of major 2483breakages in tracking -current.
