1Updating Information for FreeBSD current users. 2 3This file is maintained and copyrighted by M. Warner Losh <imp@freebsd.org>. 4See end of file for further details. For commonly done items, please see the 5COMMON ITEMS: section later in the file. These instructions assume that you 6basically know what you are doing. If not, then please consult the FreeBSD 7handbook: 8 9 https://docs.freebsd.org/en/books/handbook/cutting-edge/#makeworld 10 11Items affecting the ports and packages system can be found in 12/usr/ports/UPDATING. Please read that file before updating system packages 13and/or ports. 14 15NOTE TO PEOPLE WHO THINK THAT FreeBSD 14.x IS SLOW: 16 FreeBSD 14.x has many debugging features turned on, in both the kernel 17 and userland. These features attempt to detect incorrect use of 18 system primitives, and encourage loud failure through extra sanity 19 checking and fail stop semantics. They also substantially impact 20 system performance. If you want to do performance measurement, 21 benchmarking, and optimization, you'll want to turn them off. This 22 includes various WITNESS- related kernel options, INVARIANTS, malloc 23 debugging flags in userland, and various verbose features in the 24 kernel. Many developers choose to disable these features on build 25 machines to maximize performance. (To completely disable malloc 26 debugging, define WITH_MALLOC_PRODUCTION in /etc/src.conf and rebuild 27 world, or to merely disable the most expensive debugging functionality 28 at runtime, run "ln -s 'abort:false,junk:false' /etc/malloc.conf".) 29 3020210817: 31 As of commit 62ca9fc1ad56 OpenSSL no longer enables kernel TLS 32 by default. Users can enable kernel TLS via the "KTLS" SSL 33 option. This can be enabled globally by using a custom 34 OpenSSL config file via OPENSSL_CONF or via an 35 application-specific configuration option for applications 36 which permit setting SSL options via SSL_CONF_cmd(3). 37 3820210811: 39 Commit 3ad1e1c1ce20 changed the internal KAPI between the NFS 40 modules. Therefore, all need to be rebuilt from sources. 41 4220210730: 43 Commit b69019c14cd8 removes pf's DIOCGETSTATESNV ioctl. 44 As of be70c7a50d32 it is no longer used by userspace, but it does mean 45 users may not be able to enumerate pf states if they update the kernel 46 past b69019c14cd8 without first updating userspace past be70c7a50d32. 47 4820210729: 49 As of commit 01ad0c007964 if_bridge member interfaces can no longer 50 change their MTU. Changing the MTU of the bridge itself will change the 51 MTU on all member interfaces instead. 52 5320210716: 54 Commit ee29e6f31111 changed the internal KAPI between the nfscommon 55 and nfsd modules. Therefore, both need to be rebuilt from sources. 56 Bump __FreeBSD_version to 1400026 for this KAPI change. 57 5820210715: 59 The 20210707 awk update brought in a change in behavior. This has 60 been corrected as of d4d252c49976. Between these dates, if you 61 installed a new awk binary, you may not be able to build a new 62 kernel because the change in behavior affected the genoffset 63 script used to build the kernel. If you did update, the fix is 64 to update your sources past the above hash and do 65 % cd usr.bin/awk 66 % make clean all 67 % sudo -E make install 68 to enable building kernels again. 69 7020210708: 71 Commit 1e0a518d6548 changed the internal KAPI between the NFS 72 modules. They all need to be rebuilt from sources. I did not 73 bump __FreeBSD_version, since it was bumped recently. 74 7520210707: 76 awk has been updated to the latest one-true-awk version 20210215. 77 This contains a number of minor bug fixes. 78 7920210624: 80 The NFSv4 client now uses the highest minor version of NFSv4 81 supported by the NFSv4 server by default instead of minor version 0, 82 for NFSv4 mounts. 83 The "minorversion" mount option may be used to override this default. 84 8520210618: 86 Bump __FreeBSD_version to 1400024 for LinuxKPI changes. 87 Most notably netdev.h can change now as the (last) dependencies 88 (mlx4/ofed) are now using struct ifnet directly, but also for PCI 89 additions and others. 90 9120210618: 92 The directory "blacklisted" under /usr/share/certs/ has been 93 renamed to "untrusted". 94 9520210611: 96 svnlite has been removed from base. Should you need svn for any reason 97 please install the svn package or port. 98 9920210611: 100 Commit e1a907a25cfa changed the internal KAPI between the krpc 101 and nfsserver. As such, both modules must be rebuilt from 102 sources. Bump __FreeBSD_version to 1400022. 103 10420210610: 105 The an(4) driver has been removed from FreeBSD. 106 10720210608: 108 The vendor/openzfs branch was renamed to vendor/openzfs/legacy to 109 start tracking OpenZFS upstream more closely. Please see 110https://lists.freebsd.org/archives/freebsd-current/2021-June/000153.html 111 for details on how to correct any errors that might result. The 112 short version is that you need to remove the old branch locally: 113 git update-ref -d refs/remotes/freebsd/vendor/openzfs 114 (assuming your upstream origin is named 'freebsd'). 115 11620210525: 117 Commits 17accc08ae15 and de102f870501 add new files to LinuxKPI 118 which break drm-kmod. In addition various other additions where 119 comitted. Bump __FreeBSD_version to 1400015 to be able to detect this. 120 12120210513: 122 Commit ca179c4d74f2 changed the package in which the OpenSSL 123 libraries and utilities are packaged. 124 It is recommended for pkgbase user to do: 125 pkg install -f FreeBSD-openssl 126 before pkg upgrade otherwise some dependencies might not be met 127 and pkg will stop working as libssl will not be present anymore 128 on the system. 129 13020210426: 131 Commit 875977314881 changed the internal KAPI between 132 the nfsd and nfscommon modules. As such these modules 133 need to be rebuilt from sources. 134 Without this patch in your NFSv4.1/4.2 server, enabling 135 delegations by setting vfs.nfsd.issue_delegations non-zero 136 is not recommended. 137 13820210411: 139 Commit 7763814fc9c2 changed the internal KAPI between 140 the krpc and NFS. As such, the krpc, nfscommon and 141 nfscl modules must all be rebuilt from sources. 142 Without this patch, NFSv4.1/4.2 mounts should not 143 be done with the nfscbd(8) daemon running, to avoid 144 needing a working back channel for server->client RPCs. 145 14620210330: 147 Commit 01ae8969a9ee fixed the NFSv4.1/4.2 server so that it 148 handles binding of the back channel as required by RFC5661. 149 Until this patch is in your server, avoid use of the "nconnects" 150 mount option for Linux NFSv4.1/4.2 mounts. 151 15220210225: 153 For 64-bit architectures the base system is now built with Position 154 Independent Executable (PIE) support enabled by default. It may be 155 disabled using the WITHOUT_PIE knob. A clean build is required. 156 15720210128: 158 Various LinuxKPI functionality was added which conflicts with DRM. 159 Please update your drm-kmod port to after the __FreeBSD_verison 1400003 160 update. 161 16220210108: 163 PC Card attachments for all devices have been removed. In the case of 164 wi and cmx, the entire drivers were removed because they were only 165 PC Card devices. FreeBSD_version 1300134 should be used for this 166 since it was bumped so recently. 167 16820210107: 169 Transport-independent parts of HID support have been split off the USB 170 code in to separate subsystem. Kernel configs which include one of 171 ums, ukbd, uhid, atp, wsp, wmt, uaudio, ugold or ucycom drivers should 172 be updated with adding of "device hid" line. 173 17420210105: 175 ncurses installation has been modified to only keep the widechar 176 enabled version. Incremental build is broken for that change, so it 177 requires a clean build. 178 17920201223: 180 The FreeBSD project has migrated from Subversion to Git. Temporary 181 instructions can be found at 182 https://github.com/bsdimp/freebsd-git-docs/blob/main/src-cvt.md 183 and other documents in that repo. 184 18520201216: 186 The services database has been updated to cover more of the basic 187 services expected in a modern system. The database is big enough 188 that it will cause issues in mergemaster in Releases previous to 189 12.2 and 11.3, or in very old current systems from before r358154. 190 19120201215: 192 Obsolete in-tree GDB 6.1.1 has been removed. GDB (including kgdb) 193 may be installed from ports or packages. 194 19520201124: 196 ping6 has been merged into ping. It can now be called as "ping -6". 197 See ping(8) for details. 198 19920201108: 200 Default value of net.add_addr_allfibs has been changed to 0. 201 If you have multi-fib configuration and rely on existence of all 202 interface routes in every fib, you need to set the above sysctl to 1. 203 20420201030: 205 The internal pre-processor in the calendar(1) program has been 206 extended to support more C pre-processor commands (e.g. #ifdef, #else, 207 and #undef) and to detect unbalanced conditional statements. 208 Error messages have been extended to include the filename and line 209 number if processing stops to help fixing malformed data files. 210 21120201026: 212 All the data files for the calendar(1) program, except calendar.freebsd, 213 have been moved to the deskutils/calendar-data port, much like the 214 jewish calendar entries were moved to deskutils/hebcal years ago. After 215 make delete-old-files, you need to install it to retain full 216 functionality. calendar(1) will issue a reminder for files it can't 217 find. 218 21920200923: 220 LINT files are no longer generated. We now include the relevant NOTES 221 files. Note: This may cause conflicts with updating in some cases. 222 find sys -name LINT\* -delete 223 is suggested across this commit to remove the generated LINT files. 224 225 If you have tried to update with generated files there, the svn 226 command you want to un-auger the tree is 227 cd sys/amd64/conf 228 svn revert -R . 229 and then do the above find from the top level. Substitute 'amd64' 230 above with where the error message indicates a conflict. 231 23220200824: 233 OpenZFS support has been integrated. Do not upgrade root pools until 234 the loader is updated to support zstd. Furthermore, we caution against 235 'zpool upgrade' for the next few weeks. The change should be transparent 236 unless you want to use new features. 237 238 Not all "NO_CLEAN" build scenarios work across these changes. Many 239 scenarios have been tested and fixed, but rebuilding kernels without 240 rebuilding world may fail. 241 242 The ZFS cache file has moved from /boot to /etc to match the OpenZFS 243 upstream default. A fallback to /boot has been added for mountroot. 244 245 Pool auto import behavior at boot has been moved from the kernel module 246 to an explicit "zpool import -a" in one of the rc scripts enabled by 247 zfs_enable=YES. This means your non-root zpools won't auto import until 248 you upgrade your /etc/rc.d files. 249 25020200824: 251 The resume code now notifies devd with the 'kernel' system 252 rather than the old 'kern' subsystem to be consistent with 253 other use. The old notification will be created as well, but 254 will be removed prior to FreeBSD 14.0. 255 25620200821: 257 r362275 changed the internal API between the kernel RPC and the 258 NFS modules. As such, all the modules must be recompiled from 259 sources. 260 26120200817: 262 r364330 modified the internal API used between the NFS modules. 263 As such, all the NFS modules must be re-compiled from sources. 264 26520200816: 266 Clang, llvm, lld, lldb, compiler-rt, libc++, libunwind and openmp have 267 been upgraded to 11.0.0. Please see the 20141231 entry below for 268 information about prerequisites and upgrading, if you are not already 269 using clang 3.5.0 or higher. 270 27120200810: 272 r364092 modified the internal ABI used between the kernel NFS 273 modules. As such, all of these modules need to be rebuilt 274 from sources, so a version bump was done. 275 27620200807: 277 Makefile.inc has been updated to work around the issue documented in 278 20200729. It was a case where the optimization of using symbolic links 279 to point to binaries created a situation where we'd run new binaries 280 with old libraries starting midway through the installworld process. 281 28220200729: 283 r363679 has redefined some undefined behavior in regcomp(3); notably, 284 extraneous escapes of most ordinary characters will no longer be 285 accepted. An exp-run has identified all of the problems with this in 286 ports, but other non-ports software may need extra escapes removed to 287 continue to function. 288 289 Because of this change, installworld may encounter the following error 290 from rtld: Undefined symbol "regcomp@FBSD_1.6" -- It is imperative that 291 you do not halt installworld. Instead, let it run to completion (whether 292 successful or not) and run installworld once more. 293 29420200627: 295 A new implementation of bc and dc has been imported in r362681. This 296 implementation corrects non-conformant behavior of the previous bc 297 and adds GNU bc compatible options. It offers a number of extensions, 298 is much faster on large values, and has support for message catalogs 299 (a number of languages are already supported, contributions of further 300 languages welcome). The option WITHOUT_GH_BC can be used to build the 301 world with the previous versions of bc and dc. 302 30320200625: 304 r362639 changed the internal API used between the NFS kernel modules. 305 As such, they all need to be rebuilt from sources. 306 30720200613: 308 r362158 changed the arguments for VFS_CHECKEXP(). As such, any 309 out of tree file systems need to be modified and rebuilt. 310 Also, any file systems that are modules must be rebuilt. 311 31220200604: 313 read(2) of a directory fd is now rejected by default. root may 314 re-enable it for system root only on non-ZFS filesystems with the 315 security.bsd.allow_read_dir sysctl(8) MIB if 316 security.bsd.suser_enabled=1. 317 318 It may be advised to setup aliases for grep to default to `-d skip` if 319 commonly non-recursively grepping a list that includes directories and 320 the potential for the resulting stderr output is not tolerable. Example 321 aliases are now installed, commented out, in /root/.cshrc and 322 /root/.shrc. 323 32420200523: 325 Clang, llvm, lld, lldb, compiler-rt, libc++, libunwind and openmp have 326 been upgraded to 10.0.1. Please see the 20141231 entry below for 327 information about prerequisites and upgrading, if you are not already 328 using clang 3.5.0 or higher. 329 33020200512: 331 Support for obsolete compilers has been removed from the build system. 332 Clang 6 and GCC 6.4 are the minimum supported versions. 333 33420200424: 335 closefrom(2) has been moved under COMPAT12, and replaced in libc with a 336 stub that calls close_range(2). If using a custom kernel configuration, 337 you may want to ensure that the COMPAT_FREEBSD12 option is included, as 338 a slightly older -CURRENT userland and older FreeBSD userlands may not 339 be functional without closefrom(2). 340 34120200414: 342 Upstream DTS from Linux 5.6 was merged and they now have the SID 343 and THS (Secure ID controller and THermal Sensor) node present. 344 The DTB overlays have now been removed from the tree for the H3/H5 and 345 A64 SoCs and the aw_sid and aw_thermal driver have been updated to 346 deal with upstream DTS. If you are using those overlays you need to 347 remove them from loader.conf and update the DTBs on the FAT partition. 348 34920200310: 350 Clang, llvm, lld, lldb, compiler-rt, libc++, libunwind and openmp have 351 been upgraded to 10.0.0. Please see the 20141231 entry below for 352 information about prerequisites and upgrading, if you are not already 353 using clang 3.5.0 or higher. 354 35520200309: 356 The amd(8) automount daemon has been removed from the source tree. 357 As of FreeBSD 10.1 autofs(5) is the preferred tool for automounting. 358 amd is still available in the sysutils/am-utils port. 359 36020200301: 361 Removed brooktree driver (bktr.4) from the tree. 362 36320200229: 364 The WITH_GPL_DTC option has been removed. The BSD-licenced device tree 365 compiler in usr.bin/dtc is used on all architectures which use dtc, and 366 the GPL dtc is available (if needed) from the sysutils/dtc port. 367 36820200229: 369 The WITHOUT_LLVM_LIBUNWIND option has been removed. LLVM's libunwind 370 is used by all supported CPU architectures. 371 37220200229: 373 GCC 4.2.1 has been removed from the tree. The WITH_GCC, 374 WITH_GCC_BOOTSTRAP, and WITH_GNUCXX options are no longer available. 375 Users who wish to build FreeBSD with GCC must use the external toolchain 376 ports or packages. 377 37820200220: 379 ncurses has been updated to a newer version (6.2-20200215). Given the ABI 380 has changed, users will have to rebuild all the ports that are linked to 381 ncurses. 382 38320200217: 384 The size of struct vnet and the magic cookie have changed. 385 Users need to recompile libkvm and all modules using VIMAGE 386 together with their new kernel. 387 38820200212: 389 Defining the long deprecated NO_CTF, NO_DEBUG_FILES, NO_INSTALLLIB, 390 NO_MAN, NO_PROFILE, and NO_WARNS variables is now an error. Update 391 your Makefiles and scripts to define MK_<var>=no instead as required. 392 393 One exception to this is that program or library Makefiles should 394 define MAN to empty rather than setting MK_MAN=no. 395 39620200108: 397 Clang/LLVM is now the default compiler and LLD the default 398 linker for riscv64. 399 40020200107: 401 make universe no longer uses GCC 4.2.1 on any architectures. 402 Architectures not supported by in-tree Clang/LLVM require an 403 external toolchain package. 404 40520200104: 406 GCC 4.2.1 is now not built by default, as part of the GCC 4.2.1 407 retirement plan. Specifically, the GCC, GCC_BOOTSTRAP, and GNUCXX 408 options default to off for all supported CPU architectures. As a 409 short-term transition aid they may be enabled via WITH_* options. 410 GCC 4.2.1 is expected to be removed from the tree on 2020-03-31. 411 41220200102: 413 Support for armv5 has been disconnected and is being removed. The 414 machine combination MACHINE=arm MACHINE_ARCH=arm is no longer valid. 415 You must now use a MACHINE_ARCH of armv6 or armv7. The default 416 MACHINE_ARCH for MACHINE=arm is now armv7. 417 41820191226: 419 Clang/LLVM is now the default compiler for all powerpc architectures. 420 LLD is now the default linker for powerpc64. The change for powerpc64 421 also includes a change to the ELFv2 ABI, incompatible with the existing 422 ABI. 423 42420191226: 425 Kernel-loadable random(4) modules are no longer unloadable. 426 42720191222: 428 Clang, llvm, lld, lldb, compiler-rt, libc++, libunwind and openmp have 429 been upgraded to 9.0.1. Please see the 20141231 entry below for 430 information about prerequisites and upgrading, if you are not already 431 using clang 3.5.0 or higher. 432 43320191212: 434 r355677 has modified the internal interface used between the 435 NFS modules in the kernel. As such, they must all be upgraded 436 simultaneously. I will do a version bump for this. 437 43820191205: 439 The root certificates of the Mozilla CA Certificate Store have been 440 imported into the base system and can be managed with the certctl(8) 441 utility. If you have installed the security/ca_root_nss port or package 442 with the ETCSYMLINK option (the default), be advised that there may be 443 differences between those included in the port and those included in 444 base due to differences in nss branch used as well as general update 445 frequency. Note also that certctl(8) cannot manage certs in the 446 format used by the security/ca_root_nss port. 447 44820191120: 449 The amd(8) automount daemon has been disabled by default, and will be 450 removed in the future. As of FreeBSD 10.1 the autofs(5) is available 451 for automounting. 452 45320191107: 454 The nctgpio and wbwd drivers have been moved to the superio bus. 455 If you have one of these drivers in a kernel configuration, then 456 you should add device superio to it. If you use one of these drivers 457 as a module and you compile a custom set of modules, then you should 458 add superio to the set. 459 46020191021: 461 KPIs for network drivers to access interface addresses have changed. 462 Users need to recompile NIC driver modules together with kernel. 463 46420191021: 465 The net.link.tap.user_open sysctl no longer prevents user opening of 466 already created /dev/tapNN devices. Access is still controlled by 467 node permissions, just like tun devices. The net.link.tap.user_open 468 sysctl is now used only to allow users to perform devfs cloning of 469 tap devices, and the subsequent open may not succeed if the user is not 470 in the appropriate group. This sysctl may be deprecated/removed 471 completely in the future. 472 47320191009: 474 mips, powerpc, and sparc64 are no longer built as part of 475 universe / tinderbox unless MAKE_OBSOLETE_GCC is defined. If 476 not defined, mips, powerpc, and sparc64 builds will look for 477 the xtoolchain binaries and if installed use them for universe 478 builds. As llvm 9.0 becomes vetted for these architectures, they 479 will be removed from the list. 480 48120191009: 482 Clang, llvm, lld, lldb, compiler-rt, libc++, libunwind and openmp have 483 been upgraded to 9.0.0. Please see the 20141231 entry below for 484 information about prerequisites and upgrading, if you are not already 485 using clang 3.5.0 or higher. 486 48720191003: 488 The hpt27xx, hptmv, hptnr, and hptrr drivers have been removed from 489 GENERIC. They are available as modules and can be loaded by adding 490 to /boot/loader.conf hpt27xx_load="YES", hptmv_load="YES", 491 hptnr_load="YES", or hptrr_load="YES", respectively. 492 49320190913: 494 ntpd no longer by default locks its pages in memory, allowing them 495 to be paged out by the kernel. Use rlimit memlock to restore 496 historic BSD behaviour. For example, add "rlimit memlock 32" 497 to ntp.conf to lock up to 32 MB of ntpd address space in memory. 498 49920190823: 500 Several of ping6's options have been renamed for better consistency 501 with ping. If you use any of -ARWXaghmrtwx, you must update your 502 scripts. See ping6(8) for details. 503 50420190727: 505 The vfs.fusefs.sync_unmount and vfs.fusefs.init_backgrounded sysctls 506 and the "-o sync_unmount" and "-o init_backgrounded" mount options have 507 been removed from mount_fusefs(8). You can safely remove them from 508 your scripts, because they had no effect. 509 510 The vfs.fusefs.fix_broken_io, vfs.fusefs.sync_resize, 511 vfs.fusefs.refresh_size, vfs.fusefs.mmap_enable, 512 vfs.fusefs.reclaim_revoked, and vfs.fusefs.data_cache_invalidate 513 sysctls have been removed. If you felt the need to set any of them to 514 a non-default value, please tell asomers@FreeBSD.org why. 515 51620190713: 517 Default permissions on the /var/account/acct file (and copies of it 518 rotated by periodic daily scripts) are changed from 0644 to 0640 519 because the file contains sensitive information that should not be 520 world-readable. If the /var/account directory must be created by 521 rc.d/accounting, the mode used is now 0750. Admins who use the 522 accounting feature are encouraged to change the mode of an existing 523 /var/account directory to 0750 or 0700. 524 52520190620: 526 Entropy collection and the /dev/random device are no longer optional 527 components. The "device random" option has been removed. 528 Implementations of distilling algorithms can still be made loadable 529 with "options RANDOM_LOADABLE" (e.g., random_fortuna.ko). 530 53120190612: 532 Clang, llvm, lld, lldb, compiler-rt, libc++, libunwind and openmp have 533 been upgraded to 8.0.1. Please see the 20141231 entry below for 534 information about prerequisites and upgrading, if you are not already 535 using clang 3.5.0 or higher. 536 53720190608: 538 A fix was applied to i386 kernel modules to avoid panics with 539 dpcpu or vnet. Users need to recompile i386 kernel modules 540 having pcpu or vnet sections or they will refuse to load. 541 54220190513: 543 User-wired pages now have their own counter, 544 vm.stats.vm.v_user_wire_count. The vm.max_wired sysctl was renamed 545 to vm.max_user_wired and changed from an unsigned int to an unsigned 546 long. bhyve VMs wired with the -S are now subject to the user 547 wiring limit; the vm.max_user_wired sysctl may need to be tuned to 548 avoid running into the limit. 549 55020190507: 551 The IPSEC option has been removed from GENERIC. Users requiring 552 ipsec(4) must now load the ipsec(4) kernel module. 553 55420190507: 555 The tap(4) driver has been folded into tun(4), and the module has been 556 renamed to tuntap. You should update any kld_list="if_tap" or 557 kld_list="if_tun" entries in /etc/rc.conf, if_tap_load="YES" or 558 if_tun_load="YES" entries in /boot/loader.conf to load the if_tuntap 559 module instead, and "device tap" or "device tun" entries in kernel 560 config files to select the tuntap device instead. 561 56220190418: 563 The following knobs have been added related to tradeoffs between 564 safe use of the random device and availability in the absence of 565 entropy: 566 567 kern.random.initial_seeding.bypass_before_seeding: tunable; set 568 non-zero to bypass the random device prior to seeding, or zero to 569 block random requests until the random device is initially seeded. 570 For now, set to 1 (unsafe) by default to restore pre-r346250 boot 571 availability properties. 572 573 kern.random.initial_seeding.read_random_bypassed_before_seeding: 574 read-only diagnostic sysctl that is set when bypass is enabled and 575 read_random(9) is bypassed, to enable programmatic handling of this 576 initial condition, if desired. 577 578 kern.random.initial_seeding.arc4random_bypassed_before_seeding: 579 Similar to the above, but for for arc4random(9) initial seeding. 580 581 kern.random.initial_seeding.disable_bypass_warnings: tunable; set 582 non-zero to disable warnings in dmesg when the same conditions are 583 met as for the diagnostic sysctls above. Defaults to zero, i.e., 584 produce warnings in dmesg when the conditions are met. 585 58620190416: 587 The loadable random module KPI has changed; the random_infra_init() 588 routine now requires a 3rd function pointer for a bool (*)(void) 589 method that returns true if the random device is seeded (and 590 therefore unblocked). 591 59220190404: 593 r345895 reverts r320698. This implies that an nfsuserd(8) daemon 594 built from head sources between r320757 (July 6, 2017) and 595 r338192 (Aug. 22, 2018) will not work unless the "-use-udpsock" 596 is added to the command line. 597 nfsuserd daemons built from head sources that are post-r338192 are 598 not affected and should continue to work. 599 60020190320: 601 The fuse(4) module has been renamed to fusefs(4) for consistency with 602 other filesystems. You should update any kld_load="fuse" entries in 603 /etc/rc.conf, fuse_load="YES" entries in /boot/loader.conf, and 604 "options FUSE" entries in kernel config files. 605 60620190304: 607 Clang, llvm, lld, lldb, compiler-rt and libc++ have been upgraded to 608 8.0.0. Please see the 20141231 entry below for information about 609 prerequisites and upgrading, if you are not already using clang 3.5.0 610 or higher. 611 61220190226: 613 geom_uzip(4) depends on the new module xz. If geom_uzip is statically 614 compiled into your custom kernel, add 'device xz' statement to the 615 kernel config. 616 61720190219: 618 drm and drm2 have been removed from the tree. Please see 619 https://wiki.freebsd.org/Graphics for the latest information on 620 migrating to the drm ports. 621 62220190131: 623 Iflib is no longer unconditionally compiled into the kernel. Drivers 624 using iflib and statically compiled into the kernel, now require 625 the 'device iflib' config option. For the same drivers loaded as 626 modules on kernels not having 'device iflib', the iflib.ko module 627 is loaded automatically. 628 62920190125: 630 The IEEE80211_AMPDU_AGE and AH_SUPPORT_AR5416 kernel configuration 631 options no longer exist since r343219 and r343427 respectively; 632 nothing uses them, so they should be just removed from custom 633 kernel config files. 634 63520181230: 636 r342635 changes the way efibootmgr(8) works by requiring users to add 637 the -b (bootnum) parameter for commands where the bootnum was previously 638 specified with each option. For example 'efibootmgr -B 0001' is now 639 'efibootmgr -B -b 0001'. 640 64120181220: 642 r342286 modifies the NFSv4 server so that it obeys vfs.nfsd.nfs_privport 643 in the same as it is applied to NFSv2 and 3. This implies that NFSv4 644 servers that have vfs.nfsd.nfs_privport set will only allow mounts 645 from clients using a reserved port. Since both the FreeBSD and Linux 646 NFSv4 clients use reserved ports by default, this should not affect 647 most NFSv4 mounts. 648 64920181219: 650 The XLP config has been removed. We can't support 64-bit atomics in this 651 kernel because it is running in 32-bit mode. XLP users must transition 652 to running a 64-bit kernel (XLP64 or XLPN32). 653 654 The mips GXEMUL support has been removed from FreeBSD. MALTA* + qemu is 655 the preferred emulator today and we don't need two different ones. 656 657 The old sibyte / swarm / Broadcom BCM1250 support has been 658 removed from the mips port. 659 66020181211: 661 Clang, llvm, lld, lldb, compiler-rt and libc++ have been upgraded to 662 7.0.1. Please see the 20141231 entry below for information about 663 prerequisites and upgrading, if you are not already using clang 3.5.0 664 or higher. 665 66620181211: 667 Remove the timed and netdate programs from the base tree. Setting 668 the time with these daemons has been obsolete for over a decade. 669 67020181126: 671 On amd64, arm64 and armv7 (architectures that install LLVM's ld.lld 672 linker as /usr/bin/ld) GNU ld is no longer installed as ld.bfd, as 673 it produces broken binaries when ifuncs are in use. Users needing 674 GNU ld should install the binutils port or package. 675 67620181123: 677 The BSD crtbegin and crtend code has been enabled by default. It has 678 had extensive testing on amd64, arm64, and i386. It can be disabled 679 by building a world with -DWITHOUT_BSD_CRTBEGIN. 680 68120181115: 682 The set of CTM commands (ctm, ctm_smail, ctm_rmail, ctm_dequeue) 683 has been converted to a port (misc/ctm) and will be removed from 684 FreeBSD-13. It is available as a package (ctm) for all supported 685 FreeBSD versions. 686 68720181110: 688 The default newsyslog.conf(5) file has been changed to only include 689 files in /etc/newsyslog.conf.d/ and /usr/local/etc/newsyslog.conf.d/ if 690 the filenames end in '.conf' and do not begin with a '.'. 691 692 You should check the configuration files in these two directories match 693 this naming convention. You can verify which configuration files are 694 being included using the command: 695 $ newsyslog -Nrv 696 69720181015: 698 Ports for the DRM modules have been simplified. Now, amd64 users should 699 just install the drm-kmod port. All others should install 700 drm-legacy-kmod. 701 702 Graphics hardware that's newer than about 2010 usually works with 703 drm-kmod. For hardware older than 2013, however, some users will need 704 to use drm-legacy-kmod if drm-kmod doesn't work for them. Hardware older 705 than 2008 usually only works in drm-legacy-kmod. The graphics team can 706 only commit to hardware made since 2013 due to the complexity of the 707 market and difficulty to test all the older cards effectively. If you 708 have hardware supported by drm-kmod, you are strongly encouraged to use 709 that as you will get better support. 710 711 Other than KPI chasing, drm-legacy-kmod will not be updated. As outlined 712 elsewhere, the drm and drm2 modules will be eliminated from the src base 713 soon (with a limited exception for arm). Please update to the package 714 asap and report any issues to x11@freebsd.org. 715 716 Generally, anybody using the drm*-kmod packages should add 717 WITHOUT_DRM_MODULE=t and WITHOUT_DRM2_MODULE=t to avoid nasty 718 cross-threading surprises, especially with automatic driver 719 loading from X11 startup. These will become the defaults in 13-current 720 shortly. 721 72220181012: 723 The ixlv(4) driver has been renamed to iavf(4). As a consequence, 724 custom kernel and module loading configuration files must be updated 725 accordingly. Moreover, interfaces previous presented as ixlvN to the 726 system are now exposed as iavfN and network configuration files must 727 be adjusted as necessary. 728 72920181009: 730 OpenSSL has been updated to version 1.1.1. This update included 731 additional various API changes throughout the base system. It is 732 important to rebuild third-party software after upgrading. The value 733 of __FreeBSD_version has been bumped accordingly. 734 73520181006: 736 The legacy DRM modules and drivers have now been added to the loader's 737 module blacklist, in favor of loading them with kld_list in rc.conf(5). 738 The module blacklist may be overridden with the loader.conf(5) 739 'module_blacklist' variable, but loading them via rc.conf(5) is strongly 740 encouraged. 741 74220181002: 743 The cam(4) based nda(4) driver will be used over nvd(4) by default on 744 powerpc64. You may set 'options NVME_USE_NVD=1' in your kernel conf or 745 loader tunable 'hw.nvme.use_nvd=1' if you wish to use the existing 746 driver. Make sure to edit /boot/etc/kboot.conf and fstab to use the 747 nda device name. 748 74920180913: 750 Reproducible build mode is now on by default, in preparation for 751 FreeBSD 12.0. This eliminates build metadata such as the user, 752 host, and time from the kernel (and uname), unless the working tree 753 corresponds to a modified checkout from a version control system. 754 The previous behavior can be obtained by setting the /etc/src.conf 755 knob WITHOUT_REPRODUCIBLE_BUILD. 756 75720180826: 758 The Yarrow CSPRNG has been removed from the kernel as it has not been 759 supported by its designers since at least 2003. Fortuna has been the 760 default since FreeBSD-11. 761 76220180822: 763 devctl freeze/thaw have gone into the tree, the rc scripts have been 764 updated to use them and devmatch has been changed. You should update 765 kernel, userland and rc scripts all at the same time. 766 76720180818: 768 The default interpreter has been switched from 4th to Lua. 769 LOADER_DEFAULT_INTERP, documented in build(7), will override the default 770 interpreter. If you have custom FORTH code you will need to set 771 LOADER_DEFAULT_INTERP=4th (valid values are 4th, lua or simp) in 772 src.conf for the build. This will create default hard links between 773 loader and loader_4th instead of loader and loader_lua, the new default. 774 If you are using UEFI it will create the proper hard link to loader.efi. 775 776 bhyve uses userboot.so. It remains 4th-only until some issues are solved 777 regarding coexisting with multiple versions of FreeBSD are resolved. 778 77920180815: 780 ls(1) now respects the COLORTERM environment variable used in other 781 systems and software to indicate that a colored terminal is both 782 supported and desired. If ls(1) is suddenly emitting colors, they may 783 be disabled again by either removing the unwanted COLORTERM from your 784 environment, or using `ls --color=never`. The ls(1) specific CLICOLOR 785 may not be observed in a future release. 786 78720180808: 788 The default pager for most commands has been changed to "less". To 789 restore the old behavior, set PAGER="more" and MANPAGER="more -s" in 790 your environment. 791 79220180731: 793 The jedec_ts(4) driver has been removed. A superset of its functionality 794 is available in the jedec_dimm(4) driver, and the manpage for that 795 driver includes migration instructions. If you have "device jedec_ts" 796 in your kernel configuration file, it must be removed. 797 79820180730: 799 amd64/GENERIC now has EFI runtime services, EFIRT, enabled by default. 800 This should have no effect if the kernel is booted via BIOS/legacy boot. 801 EFIRT may be disabled via a loader tunable, efi.rt.disabled, if a system 802 has a buggy firmware that prevents a successful boot due to use of 803 runtime services. 804 80520180727: 806 Atmel AT91RM9200 and AT91SAM9, Cavium CNS 11xx and XScale 807 support has been removed from the tree. These ports were 808 obsolete and/or known to be broken for many years. 809 81020180723: 811 loader.efi has been augmented to participate more fully in the 812 UEFI boot manager protocol. loader.efi will now look at the 813 BootXXXX environment variable to determine if a specific kernel 814 or root partition was specified. XXXX is derived from BootCurrent. 815 efibootmgr(8) manages these standard UEFI variables. 816 81720180720: 818 zfsloader's functionality has now been folded into loader. 819 zfsloader is no longer necessary once you've updated your 820 boot blocks. For a transition period, we will install a 821 hardlink for zfsloader to loader to allow a smooth transition 822 until the boot blocks can be updated (hard link because old 823 zfs boot blocks don't understand symlinks). 824 82520180719: 826 ARM64 now have efifb support, if you want to have serial console 827 on your arm64 board when an screen is connected and the bootloader 828 setup a frame buffer for us to use, just add : 829 boot_serial=YES 830 boot_multicons=YES 831 in /boot/loader.conf 832 For Raspberry Pi 3 (RPI) users, this is needed even if you don't have 833 an screen connected as the firmware will setup a frame buffer are that 834 u-boot will expose as an EFI frame buffer. 835 83620180719: 837 New uid:gid added, ntpd:ntpd (123:123). Be sure to run mergemaster 838 or take steps to update /etc/passwd before doing installworld on 839 existing systems. Do not skip the "mergemaster -Fp" step before 840 installworld, as described in the update procedures near the bottom 841 of this document. Also, rc.d/ntpd now starts ntpd(8) as user ntpd 842 if the new mac_ntpd(4) policy is available, unless ntpd_flags or 843 the ntp config file contain options that change file/dir locations. 844 When such options (e.g., "statsdir" or "crypto") are used, ntpd can 845 still be run as non-root by setting ntpd_user=ntpd in rc.conf, after 846 taking steps to ensure that all required files/dirs are accessible 847 by the ntpd user. 848 84920180717: 850 Big endian arm support has been removed. 851 85220180711: 853 The static environment setup in kernel configs is no longer mutually 854 exclusive with the loader(8) environment by default. In order to 855 restore the previous default behavior of disabling the loader(8) 856 environment if a static environment is present, you must specify 857 loader_env.disabled=1 in the static environment. 858 85920180705: 860 The ABI of syscalls used by management tools like sockstat and 861 netstat has been broken to allow 32-bit binaries to work on 862 64-bit kernels without modification. These programs will need 863 to match the kernel in order to function. External programs may 864 require minor modifications to accommodate a change of type in 865 structures from pointers to 64-bit virtual addresses. 866 86720180702: 868 On i386 and amd64 atomics are now inlined. Out of tree modules using 869 atomics will need to be rebuilt. 870 87120180701: 872 The '%I' format in the kern.corefile sysctl limits the number of 873 core files that a process can generate to the number stored in the 874 debug.ncores sysctl. The '%I' format is replaced by the single digit 875 index. Previously, if all indexes were taken the kernel would overwrite 876 only a core file with the highest index in a filename. 877 Currently the system will create a new core file if there is a free 878 index or if all slots are taken it will overwrite the oldest one. 879 88020180630: 881 Clang, llvm, lld, lldb, compiler-rt and libc++ have been upgraded to 882 6.0.1. Please see the 20141231 entry below for information about 883 prerequisites and upgrading, if you are not already using clang 3.5.0 884 or higher. 885 88620180628: 887 r335753 introduced a new quoting method. However, etc/devd/devmatch.conf 888 needed to be changed to work with it. This change was made with r335763 889 and requires a mergemaster / etcupdate / etc to update the installed 890 file. 891 89220180612: 893 r334930 changed the interface between the NFS modules, so they all 894 need to be rebuilt. r335018 did a __FreeBSD_version bump for this. 895 89620180530: 897 As of r334391 lld is the default amd64 system linker; it is installed 898 as /usr/bin/ld. Kernel build workarounds (see 20180510 entry) are no 899 longer necessary. 900 90120180530: 902 The kernel / userland interface for devinfo changed, so you'll 903 need a new kernel and userland as a pair for it to work (rebuilding 904 lib/libdevinfo is all that's required). devinfo and devmatch will 905 not work, but everything else will when there's a mismatch. 906 90720180523: 908 The on-disk format for hwpmc callchain records has changed to include 909 threadid corresponding to a given record. This changes the field offsets 910 and thus requires that libpmcstat be rebuilt before using a kernel 911 later than r334108. 912 91320180517: 914 The vxge(4) driver has been removed. This driver was introduced into 915 HEAD one week before the Exar left the Ethernet market and is not 916 known to be used. If you have device vxge in your kernel config file 917 it must be removed. 918 91920180510: 920 The amd64 kernel now requires a ld that supports ifunc to produce a 921 working kernel, either lld or a newer binutils. lld is built by default 922 on amd64, and the 'buildkernel' target uses it automatically. However, 923 it is not the default linker, so building the kernel the traditional 924 way requires LD=ld.lld on the command line (or LD=/usr/local/bin/ld for 925 binutils port/package). lld will soon be default, and this requirement 926 will go away. 927 928 NOTE: As of r334391 lld is the default system linker on amd64, and no 929 workaround is necessary. 930 93120180508: 932 The nxge(4) driver has been removed. This driver was for PCI-X 10g 933 cards made by s2io/Neterion. The company was acquired by Exar and 934 no longer sells or supports Ethernet products. If you have device 935 nxge in your kernel config file it must be removed. 936 93720180504: 938 The tz database (tzdb) has been updated to 2018e. This version more 939 correctly models time stamps in time zones with negative DST such as 940 Europe/Dublin (from 1971 on), Europe/Prague (1946/7), and 941 Africa/Windhoek (1994/2017). This does not affect the UT offsets, only 942 time zone abbreviations and the tm_isdst flag. 943 94420180502: 945 The ixgb(4) driver has been removed. This driver was for an early and 946 uncommon legacy PCI 10GbE for a single ASIC, Intel 82597EX. Intel 947 quickly shifted to the long lived ixgbe family. If you have device 948 ixgb in your kernel config file it must be removed. 949 95020180501: 951 The lmc(4) driver has been removed. This was a WAN interface 952 card that was already reportedly rare in 2003, and had an ambiguous 953 license. If you have device lmc in your kernel config file it must 954 be removed. 955 95620180413: 957 Support for Arcnet networks has been removed. If you have device 958 arcnet or device cm in your kernel config file they must be 959 removed. 960 96120180411: 962 Support for FDDI networks has been removed. If you have device 963 fddi or device fpa in your kernel config file they must be 964 removed. 965 96620180406: 967 In addition to supporting RFC 3164 formatted messages, the 968 syslogd(8) service is now capable of parsing RFC 5424 formatted 969 log messages. The main benefit of using RFC 5424 is that clients 970 may now send log messages with timestamps containing year numbers, 971 microseconds and time zone offsets. 972 973 Similarly, the syslog(3) C library function has been altered to 974 send RFC 5424 formatted messages to the local system logging 975 daemon. On systems using syslogd(8), this change should have no 976 negative impact, as long as syslogd(8) and the C library are 977 updated at the same time. On systems using a different system 978 logging daemon, it may be necessary to make configuration 979 adjustments, depending on the software used. 980 981 When using syslog-ng, add the 'syslog-protocol' flag to local 982 input sources to enable parsing of RFC 5424 formatted messages: 983 984 source src { 985 unix-dgram("/var/run/log" flags(syslog-protocol)); 986 } 987 988 When using rsyslog, disable the 'SysSock.UseSpecialParser' option 989 of the 'imuxsock' module to let messages be processed by the 990 regular RFC 3164/5424 parsing pipeline: 991 992 module(load="imuxsock" SysSock.UseSpecialParser="off") 993 994 Do note that these changes only affect communication between local 995 applications and syslogd(8). The format that syslogd(8) uses to 996 store messages on disk or forward messages to other systems 997 remains unchanged. syslogd(8) still uses RFC 3164 for these 998 purposes. Options to customize this behaviour will be added in the 999 future. Utilities that process log files stored in /var/log are 1000 thus expected to continue to function as before. 1001 1002 __FreeBSD_version has been incremented to 1200061 to denote this 1003 change. 1004 100520180328: 1006 Support for token ring networks has been removed. If you 1007 have "device token" in your kernel config you should remove 1008 it. No device drivers supported token ring. 1009 101020180323: 1011 makefs was modified to be able to tag ISO9660 El Torito boot catalog 1012 entries as EFI instead of overloading the i386 tag as done previously. 1013 The amd64 mkisoimages.sh script used to build amd64 ISO images for 1014 release was updated to use this. This may mean that makefs must be 1015 updated before "make cdrom" can be run in the release directory. This 1016 should be as simple as: 1017 1018 $ cd $SRCDIR/usr.sbin/makefs 1019 $ make depend all install 1020 102120180212: 1022 FreeBSD boot loader enhanced with Lua scripting. It's purely opt-in for 1023 now by building WITH_LOADER_LUA and WITHOUT_FORTH in /etc/src.conf. 1024 Co-existence for the transition period will come shortly. Booting is a 1025 complex environment and test coverage for Lua-enabled loaders has been 1026 thin, so it would be prudent to assume it might not work and make 1027 provisions for backup boot methods. 1028 102920180211: 1030 devmatch functionality has been turned on in devd. It will automatically 1031 load drivers for unattached devices. This may cause unexpected drivers 1032 to be loaded. Please report any problems to current@ and 1033 imp@freebsd.org. 1034 103520180114: 1036 Clang, llvm, lld, lldb, compiler-rt and libc++ have been upgraded to 1037 6.0.0. Please see the 20141231 entry below for information about 1038 prerequisites and upgrading, if you are not already using clang 3.5.0 1039 or higher. 1040 104120180110: 1042 LLVM's lld linker is now used as the FreeBSD/amd64 bootstrap linker. 1043 This means it is used to link the kernel and userland libraries and 1044 executables, but is not yet installed as /usr/bin/ld by default. 1045 1046 To revert to ld.bfd as the bootstrap linker, in /etc/src.conf set 1047 WITHOUT_LLD_BOOTSTRAP=yes 1048 104920180110: 1050 On i386, pmtimer has been removed. Its functionality has been folded 1051 into apm. It was a no-op on ACPI in current for a while now (but was 1052 still needed on i386 in FreeBSD 11 and earlier). Users may need to 1053 remove it from kernel config files. 1054 105520180104: 1056 The use of RSS hash from the network card aka flowid has been 1057 disabled by default for lagg(4) as it's currently incompatible with 1058 the lacp and loadbalance protocols. 1059 1060 This can be re-enabled by setting the following in loader.conf: 1061 net.link.lagg.default_use_flowid="1" 1062 106320180102: 1064 The SW_WATCHDOG option is no longer necessary to enable the 1065 hardclock-based software watchdog if no hardware watchdog is 1066 configured. As before, SW_WATCHDOG will cause the software 1067 watchdog to be enabled even if a hardware watchdog is configured. 1068 106920171215: 1070 r326887 fixes the issue described in the 20171214 UPDATING entry. 1071 r326888 flips the switch back to building GELI support always. 1072 107320171214: 1074 r362593 broke ZFS + GELI support for reasons unknown. However, 1075 it also broke ZFS support generally, so GELI has been turned off 1076 by default as the lesser evil in r326857. If you boot off ZFS and/or 1077 GELI, it might not be a good time to update. 1078 107920171125: 1080 PowerPC users must update loader(8) by rebuilding world before 1081 installing a new kernel, as the protocol connecting them has 1082 changed. Without the update, loader metadata will not be passed 1083 successfully to the kernel and users will have to enter their 1084 root partition at the kernel mountroot prompt to continue booting. 1085 Newer versions of loader can boot old kernels without issue. 1086 108720171110: 1088 The LOADER_FIREWIRE_SUPPORT build variable has been renamed to 1089 WITH/OUT_LOADER_FIREWIRE. LOADER_{NO_,}GELI_SUPPORT has been renamed 1090 to WITH/OUT_LOADER_GELI. 1091 109220171106: 1093 The naive and non-compliant support of posix_fallocate(2) in ZFS 1094 has been removed as of r325320. The system call now returns EINVAL 1095 when used on a ZFS file. Although the new behavior complies with the 1096 standard, some consumers are not prepared to cope with it. 1097 One known victim is lld prior to r325420. 1098 109920171102: 1100 Building in a FreeBSD src checkout will automatically create object 1101 directories now rather than store files in the current directory if 1102 'make obj' was not ran. Calling 'make obj' is no longer necessary. 1103 This feature can be disabled by setting WITHOUT_AUTO_OBJ=yes in 1104 /etc/src-env.conf (not /etc/src.conf), or passing the option in the 1105 environment. 1106 110720171101: 1108 The default MAKEOBJDIR has changed from /usr/obj/<srcdir> for native 1109 builds, and /usr/obj/<arch>/<srcdir> for cross-builds, to a unified 1110 /usr/obj/<srcdir>/<arch>. This behavior can be changed to the old 1111 format by setting WITHOUT_UNIFIED_OBJDIR=yes in /etc/src-env.conf, 1112 the environment, or with -DWITHOUT_UNIFIED_OBJDIR when building. 1113 The UNIFIED_OBJDIR option is a transitional feature that will be 1114 removed for 12.0 release; please migrate to the new format for any 1115 tools by looking up the OBJDIR used by 'make -V .OBJDIR' means rather 1116 than hardcoding paths. 1117 111820171028: 1119 The native-xtools target no longer installs the files by default to the 1120 OBJDIR. Use the native-xtools-install target with a DESTDIR to install 1121 to ${DESTDIR}/${NXTP} where NXTP defaults to /nxb-bin. 1122 112320171021: 1124 As part of the boot loader infrastructure cleanup, LOADER_*_SUPPORT 1125 options are changing from controlling the build if defined / undefined 1126 to controlling the build with explicit 'yes' or 'no' values. They will 1127 shift to WITH/WITHOUT options to match other options in the system. 1128 112920171010: 1130 libstand has turned into a private library for sys/boot use only. 1131 It is no longer supported as a public interface outside of sys/boot. 1132 113320171005: 1134 The arm port has split armv6 into armv6 and armv7. armv7 is now 1135 a valid TARGET_ARCH/MACHINE_ARCH setting. If you have an armv7 system 1136 and are running a kernel from before r324363, you will need to add 1137 MACHINE_ARCH=armv7 to 'make buildworld' to do a native build. 1138 113920171003: 1140 When building multiple kernels using KERNCONF, non-existent KERNCONF 1141 files will produce an error and buildkernel will fail. Previously 1142 missing KERNCONF files silently failed giving no indication as to 1143 why, only to subsequently discover during installkernel that the 1144 desired kernel was never built in the first place. 1145 114620170912: 1147 The default serial number format for CTL LUNs has changed. This will 1148 affect users who use /dev/diskid/* device nodes, or whose FibreChannel 1149 or iSCSI clients care about their LUNs' serial numbers. Users who 1150 require serial number stability should hardcode serial numbers in 1151 /etc/ctl.conf . 1152 115320170912: 1154 For 32-bit arm compiled for hard-float support, soft-floating point 1155 binaries now always get their shared libraries from 1156 LD_SOFT_LIBRARY_PATH (in the past, this was only used if 1157 /usr/libsoft also existed). Only users with a hard-float ld.so, but 1158 soft-float everything else should be affected. 1159 116020170826: 1161 The geli password typed at boot is now hidden. To restore the previous 1162 behavior, see geli(8) for configuration options. 1163 116420170825: 1165 Move PMTUD blackhole counters to TCPSTATS and remove them from bare 1166 sysctl values. Minor nit, but requires a rebuild of both world/kernel 1167 to complete. 1168 116920170814: 1170 "make check" behavior (made in ^/head@r295380) has been changed to 1171 execute from a limited sandbox, as opposed to executing from 1172 ${TESTSDIR}. 1173 1174 Behavioral changes: 1175 - The "beforecheck" and "aftercheck" targets are now specified. 1176 - ${CHECKDIR} (added in commit noted above) has been removed. 1177 - Legacy behavior can be enabled by setting 1178 WITHOUT_MAKE_CHECK_USE_SANDBOX in src.conf(5) or the environment. 1179 1180 If the limited sandbox mode is enabled, "make check" will execute 1181 "make distribution", then install, execute the tests, and clean up the 1182 sandbox if successful. 1183 1184 The "make distribution" and "make install" targets are typically run as 1185 root to set appropriate permissions and ownership at installation time. 1186 The end-user should set "WITH_INSTALL_AS_USER" in src.conf(5) or the 1187 environment if executing "make check" with limited sandbox mode using 1188 an unprivileged user. 1189 119020170808: 1191 Since the switch to GPT disk labels, fsck for UFS/FFS has been 1192 unable to automatically find alternate superblocks. As of r322297, 1193 the information needed to find alternate superblocks has been 1194 moved to the end of the area reserved for the boot block. 1195 Filesystems created with a newfs of this vintage or later 1196 will create the recovery information. If you have a filesystem 1197 created prior to this change and wish to have a recovery block 1198 created for your filesystem, you can do so by running fsck in 1199 foreground mode (i.e., do not use the -p or -y options). As it 1200 starts, fsck will ask ``SAVE DATA TO FIND ALTERNATE SUPERBLOCKS'' 1201 to which you should answer yes. 1202 120320170728: 1204 As of r321665, an NFSv4 server configuration that services 1205 Kerberos mounts or clients that do not support the uid/gid in 1206 owner/owner_group string capability, must explicitly enable 1207 the nfsuserd daemon by adding nfsuserd_enable="YES" to the 1208 machine's /etc/rc.conf file. 1209 121020170722: 1211 Clang, llvm, lldb, compiler-rt and libc++ have been upgraded to 5.0.0. 1212 Please see the 20141231 entry below for information about prerequisites 1213 and upgrading, if you are not already using clang 3.5.0 or higher. 1214 121520170701: 1216 WITHOUT_RCMDS is now the default. Set WITH_RCMDS if you need the 1217 r-commands (rlogin, rsh, etc.) to be built with the base system. 1218 121920170625: 1220 The FreeBSD/powerpc platform now uses a 64-bit type for time_t. This is 1221 a very major ABI incompatible change, so users of FreeBSD/powerpc must 1222 be careful when performing source upgrades. It is best to run 1223 'make installworld' from an alternate root system, either a live 1224 CD/memory stick, or a temporary root partition. Additionally, all ports 1225 must be recompiled. powerpc64 is largely unaffected, except in the case 1226 of 32-bit compatibility. All 32-bit binaries will be affected. 1227 122820170623: 1229 Forward compatibility for the "ino64" project have been committed. This 1230 will allow most new binaries to run on older kernels in a limited 1231 fashion. This prevents many of the common foot-shooting actions in the 1232 upgrade as well as the limited ability to roll back the kernel across 1233 the ino64 upgrade. Complicated use cases may not work properly, though 1234 enough simpler ones work to allow recovery in most situations. 1235 123620170620: 1237 Switch back to the BSDL dtc (Device Tree Compiler). Set WITH_GPL_DTC 1238 if you require the GPL compiler. 1239 124020170618: 1241 The internal ABI used for communication between the NFS kernel modules 1242 was changed by r320085, so __FreeBSD_version was bumped to 1243 ensure all the NFS related modules are updated together. 1244 124520170617: 1246 The ABI of struct event was changed by extending the data 1247 member to 64bit and adding ext fields. For upgrade, same 1248 precautions as for the entry 20170523 "ino64" must be 1249 followed. 1250 125120170531: 1252 The GNU roff toolchain has been removed from base. To render manpages 1253 which are not supported by mandoc(1), man(1) can fallback on GNU roff 1254 from ports (and recommends to install it). 1255 To render roff(7) documents, consider using GNU roff from ports or the 1256 heirloom doctools roff toolchain from ports via pkg install groff or 1257 via pkg install heirloom-doctools. 1258 125920170524: 1260 The ath(4) and ath_hal(4) modules now build piecemeal to allow for 1261 smaller runtime footprint builds. This is useful for embedded systems 1262 which only require one chipset support. 1263 1264 If you load it as a module, make sure this is in /boot/loader.conf: 1265 1266 if_ath_load="YES" 1267 1268 This will load the HAL, all chip/RF backends and if_ath_pci. 1269 If you have if_ath_pci in /boot/loader.conf, ensure it is after 1270 if_ath or it will not load any HAL chipset support. 1271 1272 If you want to selectively load things (eg on cheaper ARM/MIPS 1273 platforms where RAM is at a premium) you should: 1274 1275 * load ath_hal 1276 * load the chip modules in question 1277 * load ath_rate, ath_dfs 1278 * load ath_main 1279 * load if_ath_pci and/or if_ath_ahb depending upon your particular 1280 bus bind type - this is where probe/attach is done. 1281 1282 For further comments/feedback, poke adrian@ . 1283 128420170523: 1285 The "ino64" 64-bit inode project has been committed, which extends 1286 a number of types to 64 bits. Upgrading in place requires care and 1287 adherence to the documented upgrade procedure. 1288 1289 If using a custom kernel configuration ensure that the 1290 COMPAT_FREEBSD11 option is included (as during the upgrade the 1291 system will be running the ino64 kernel with the existing world). 1292 1293 For the safest in-place upgrade begin by removing previous build 1294 artifacts via "rm -rf /usr/obj/*". Then, carefully follow the full 1295 procedure documented below under the heading "To rebuild everything and 1296 install it on the current system." Specifically, a reboot is required 1297 after installing the new kernel before installing world. While an 1298 installworld normally works by accident from multiuser after rebooting 1299 the proper kernel, there are many cases where this will fail across this 1300 upgrade and installworld from single user is required. 1301 130220170424: 1303 The NATM framework including the en(4), fatm(4), hatm(4), and 1304 patm(4) devices has been removed. Consumers should plan a 1305 migration before the end-of-life date for FreeBSD 11. 1306 130720170420: 1308 GNU diff has been replaced by a BSD licensed diff. Some features of GNU 1309 diff has not been implemented, if those are needed a newer version of 1310 GNU diff is available via the diffutils package under the gdiff name. 1311 131220170413: 1313 As of r316810 for ipfilter, keep frags is no longer assumed when 1314 keep state is specified in a rule. r316810 aligns ipfilter with 1315 documentation in man pages separating keep frags from keep state. 1316 This allows keep state to be specified without forcing keep frags 1317 and allows keep frags to be specified independently of keep state. 1318 To maintain previous behaviour, also specify keep frags with 1319 keep state (as documented in ipf.conf.5). 1320 132120170407: 1322 arm64 builds now use the base system LLD 4.0.0 linker by default, 1323 instead of requiring that the aarch64-binutils port or package be 1324 installed. To continue using aarch64-binutils, set 1325 CROSS_BINUTILS_PREFIX=/usr/local/aarch64-freebsd/bin . 1326 132720170405: 1328 The UDP optimization in entry 20160818 that added the sysctl 1329 net.inet.udp.require_l2_bcast has been reverted. L2 broadcast 1330 packets will no longer be treated as L3 broadcast packets. 1331 133220170331: 1333 Binds and sends to the loopback addresses, IPv6 and IPv4, will now 1334 use any explicitly assigned loopback address available in the jail 1335 instead of using the first assigned address of the jail. 1336 133720170329: 1338 The ctl.ko module no longer implements the iSCSI target frontend: 1339 cfiscsi.ko does instead. 1340 1341 If building cfiscsi.ko as a kernel module, the module can be loaded 1342 via one of the following methods: 1343 - `cfiscsi_load="YES"` in loader.conf(5). 1344 - Add `cfiscsi` to `$kld_list` in rc.conf(5). 1345 - ctladm(8)/ctld(8), when compiled with iSCSI support 1346 (`WITH_ISCSI=yes` in src.conf(5)) 1347 1348 Please see cfiscsi(4) for more details. 1349 135020170316: 1351 The mmcsd.ko module now additionally depends on geom_flashmap.ko. 1352 Also, mmc.ko and mmcsd.ko need to be a matching pair built from the 1353 same source (previously, the dependency of mmcsd.ko on mmc.ko was 1354 missing, but mmcsd.ko now will refuse to load if it is incompatible 1355 with mmc.ko). 1356 135720170315: 1358 The syntax of ipfw(8) named states was changed to avoid ambiguity. 1359 If you have used named states in the firewall rules, you need to modify 1360 them after installworld and before rebooting. Now named states must 1361 be prefixed with colon. 1362 136320170311: 1364 The old drm (sys/dev/drm/) drivers for i915 and radeon have been 1365 removed as the userland we provide cannot use them. The KMS version 1366 (sys/dev/drm2) supports the same hardware. 1367 136820170302: 1369 Clang, llvm, lldb, compiler-rt and libc++ have been upgraded to 4.0.0. 1370 Please see the 20141231 entry below for information about prerequisites 1371 and upgrading, if you are not already using clang 3.5.0 or higher. 1372 137320170221: 1374 The code that provides support for ZFS .zfs/ directory functionality 1375 has been reimplemented. It's not possible now to create a snapshot 1376 by mkdir under .zfs/snapshot/. That should be the only user visible 1377 change. 1378 137920170216: 1380 EISA bus support has been removed. The WITH_EISA option is no longer 1381 valid. 1382 138320170215: 1384 MCA bus support has been removed. 1385 138620170127: 1387 The WITH_LLD_AS_LD / WITHOUT_LLD_AS_LD build knobs have been renamed 1388 WITH_LLD_IS_LD / WITHOUT_LLD_IS_LD, for consistency with CLANG_IS_CC. 1389 139020170112: 1391 The EM_MULTIQUEUE kernel configuration option is deprecated now that 1392 the em(4) driver conforms to iflib specifications. 1393 139420170109: 1395 The igb(4), em(4) and lem(4) ethernet drivers are now implemented via 1396 IFLIB. If you have a custom kernel configuration that excludes em(4) 1397 but you use igb(4), you need to re-add em(4) to your custom 1398 configuration. 1399 140020161217: 1401 Clang, llvm, lldb, compiler-rt and libc++ have been upgraded to 3.9.1. 1402 Please see the 20141231 entry below for information about prerequisites 1403 and upgrading, if you are not already using clang 3.5.0 or higher. 1404 140520161124: 1406 Clang, llvm, lldb, compiler-rt and libc++ have been upgraded to 3.9.0. 1407 Please see the 20141231 entry below for information about prerequisites 1408 and upgrading, if you are not already using clang 3.5.0 or higher. 1409 141020161119: 1411 The layout of the pmap structure has changed for powerpc to put the pmap 1412 statistics at the front for all CPU variations. libkvm(3) and all tools 1413 that link against it need to be recompiled. 1414 141520161030: 1416 isl(4) and cyapa(4) drivers now require a new driver, 1417 chromebook_platform(4), to work properly on Chromebook-class hardware. 1418 On other types of hardware the drivers may need to be configured using 1419 device hints. Please see the corresponding manual pages for details. 1420 142120161017: 1422 The urtwn(4) driver was merged into rtwn(4) and now consists of 1423 rtwn(4) main module + rtwn_usb(4) and rtwn_pci(4) bus-specific 1424 parts. 1425 Also, firmware for RTL8188CE was renamed due to possible name 1426 conflict (rtwnrtl8192cU(B) -> rtwnrtl8192cE(B)) 1427 142820161015: 1429 GNU rcs has been removed from base. It is available as packages: 1430 - rcs: Latest GPLv3 GNU rcs version. 1431 - rcs57: Copy of the latest version of GNU rcs (GPLv2) before it was 1432 removed from base. 1433 143420161008: 1435 Use of the cc_cdg, cc_chd, cc_hd, or cc_vegas congestion control 1436 modules now requires that the kernel configuration contain the 1437 TCP_HHOOK option. (This option is included in the GENERIC kernel.) 1438 143920161003: 1440 The WITHOUT_ELFCOPY_AS_OBJCOPY src.conf(5) knob has been retired. 1441 ELF Tool Chain's elfcopy is always installed as /usr/bin/objcopy. 1442 144320160924: 1444 Relocatable object files with the extension of .So have been renamed 1445 to use an extension of .pico instead. The purpose of this change is 1446 to avoid a name clash with shared libraries on case-insensitive file 1447 systems. On those file systems, foo.So is the same file as foo.so. 1448 144920160918: 1450 GNU rcs has been turned off by default. It can (temporarily) be built 1451 again by adding WITH_RCS knob in src.conf. 1452 Otherwise, GNU rcs is available from packages: 1453 - rcs: Latest GPLv3 GNU rcs version. 1454 - rcs57: Copy of the latest version of GNU rcs (GPLv2) from base. 1455 145620160918: 1457 The backup_uses_rcs functionality has been removed from rc.subr. 1458 145920160908: 1460 The queue(3) debugging macro, QUEUE_MACRO_DEBUG, has been split into 1461 two separate components, QUEUE_MACRO_DEBUG_TRACE and 1462 QUEUE_MACRO_DEBUG_TRASH. Define both for the original 1463 QUEUE_MACRO_DEBUG behavior. 1464 146520160824: 1466 r304787 changed some ioctl interfaces between the iSCSI userspace 1467 programs and the kernel. ctladm, ctld, iscsictl, and iscsid must be 1468 rebuilt to work with new kernels. __FreeBSD_version has been bumped 1469 to 1200005. 1470 147120160818: 1472 The UDP receive code has been updated to only treat incoming UDP 1473 packets that were addressed to an L2 broadcast address as L3 1474 broadcast packets. It is not expected that this will affect any 1475 standards-conforming UDP application. The new behaviour can be 1476 disabled by setting the sysctl net.inet.udp.require_l2_bcast to 1477 0. 1478 147920160818: 1480 Remove the openbsd_poll system call. 1481 __FreeBSD_version has been bumped because of this. 1482 148320160708: 1484 The stable/11 branch has been created from head@r302406. 1485 148620160622: 1487 The libc stub for the pipe(2) system call has been replaced with 1488 a wrapper that calls the pipe2(2) system call and the pipe(2) 1489 system call is now only implemented by the kernels that include 1490 "options COMPAT_FREEBSD10" in their config file (this is the 1491 default). Users should ensure that this option is enabled in 1492 their kernel or upgrade userspace to r302092 before upgrading their 1493 kernel. 1494 149520160527: 1496 CAM now strips the leading spaces from each SCSI disk's serial number. 1497 This will affect users who create UFS filesystems on SCSI disks using 1498 those disk's diskid device nodes. For example, if /etc/fstab 1499 previously contained a line like 1500 "/dev/diskid/DISK-%20%20%20%20%20%20%20ABCDEFG0123456", you should 1501 change it to "/dev/diskid/DISK-ABCDEFG0123456". Users of geom 1502 transforms like gmirror may also be affected. ZFS users should 1503 generally be fine. 1504 150520160523: 1506 The bitstring(3) API has been updated with new functionality and 1507 improved performance. But it is binary-incompatible with the old API. 1508 Objects built with the new headers may not be linked against objects 1509 built with the old headers. 1510 151120160520: 1512 The brk and sbrk functions have been removed from libc on arm64. 1513 Binutils from ports has been updated to not link to these 1514 functions and should be updated to the latest version before 1515 installing a new libc. 1516 151720160517: 1518 The armv6 port now defaults to hard float ABI. Limited support 1519 for running both hardfloat and soft float on the same system 1520 is available using the libraries installed with -DWITH_LIBSOFT. 1521 This has only been tested as an upgrade path for installworld 1522 and packages may fail or need manual intervention to run. New 1523 packages will be needed. 1524 1525 To update an existing self-hosted armv6hf system, you must add 1526 TARGET_ARCH=armv6 on the make command line for both the build 1527 and the install steps. 1528 152920160510: 1530 Kernel modules compiled outside of a kernel build now default to 1531 installing to /boot/modules instead of /boot/kernel. Many kernel 1532 modules built this way (such as those in ports) already overrode 1533 KMODDIR explicitly to install into /boot/modules. However, 1534 manually building and installing a module from /sys/modules will 1535 now install to /boot/modules instead of /boot/kernel. 1536 153720160414: 1538 The CAM I/O scheduler has been committed to the kernel. There should be 1539 no user visible impact. This does enable NCQ Trim on ada SSDs. While the 1540 list of known rogues that claim support for this but actually corrupt 1541 data is believed to be complete, be on the lookout for data 1542 corruption. The known rogue list is believed to be complete: 1543 1544 o Crucial MX100, M550 drives with MU01 firmware. 1545 o Micron M510 and M550 drives with MU01 firmware. 1546 o Micron M500 prior to MU07 firmware 1547 o Samsung 830, 840, and 850 all firmwares 1548 o FCCT M500 all firmwares 1549 1550 Crucial has firmware http://www.crucial.com/usa/en/support-ssd-firmware 1551 with working NCQ TRIM. For Micron branded drives, see your sales rep for 1552 updated firmware. Black listed drives will work correctly because these 1553 drives work correctly so long as no NCQ TRIMs are sent to them. Given 1554 this list is the same as found in Linux, it's believed there are no 1555 other rogues in the market place. All other models from the above 1556 vendors work. 1557 1558 To be safe, if you are at all concerned, you can quirk each of your 1559 drives to prevent NCQ from being sent by setting: 1560 kern.cam.ada.X.quirks="0x2" 1561 in loader.conf. If the drive requires the 4k sector quirk, set the 1562 quirks entry to 0x3. 1563 156420160330: 1565 The FAST_DEPEND build option has been removed and its functionality is 1566 now the one true way. The old mkdep(1) style of 'make depend' has 1567 been removed. See 20160311 for further details. 1568 156920160317: 1570 Resource range types have grown from unsigned long to uintmax_t. All 1571 drivers, and anything using libdevinfo, need to be recompiled. 1572 157320160311: 1574 WITH_FAST_DEPEND is now enabled by default for in-tree and out-of-tree 1575 builds. It no longer runs mkdep(1) during 'make depend', and the 1576 'make depend' stage can safely be skipped now as it is auto ran 1577 when building 'make all' and will generate all SRCS and DPSRCS before 1578 building anything else. Dependencies are gathered at compile time with 1579 -MF flags kept in separate .depend files per object file. Users should 1580 run 'make cleandepend' once if using -DNO_CLEAN to clean out older 1581 stale .depend files. 1582 158320160306: 1584 On amd64, clang 3.8.0 can now insert sections of type AMD64_UNWIND into 1585 kernel modules. Therefore, if you load any kernel modules at boot time, 1586 please install the boot loaders after you install the kernel, but before 1587 rebooting, e.g.: 1588 1589 make buildworld 1590 make buildkernel KERNCONF=YOUR_KERNEL_HERE 1591 make installkernel KERNCONF=YOUR_KERNEL_HERE 1592 make -C sys/boot install 1593 <reboot in single user> 1594 1595 Then follow the usual steps, described in the General Notes section, 1596 below. 1597 159820160305: 1599 Clang, llvm, lldb and compiler-rt have been upgraded to 3.8.0. Please 1600 see the 20141231 entry below for information about prerequisites and 1601 upgrading, if you are not already using clang 3.5.0 or higher. 1602 160320160301: 1604 The AIO subsystem is now a standard part of the kernel. The 1605 VFS_AIO kernel option and aio.ko kernel module have been removed. 1606 Due to stability concerns, asynchronous I/O requests are only 1607 permitted on sockets and raw disks by default. To enable 1608 asynchronous I/O requests on all file types, set the 1609 vfs.aio.enable_unsafe sysctl to a non-zero value. 1610 161120160226: 1612 The ELF object manipulation tool objcopy is now provided by the 1613 ELF Tool Chain project rather than by GNU binutils. It should be a 1614 drop-in replacement, with the addition of arm64 support. The 1615 (temporary) src.conf knob WITHOUT_ELFCOPY_AS_OBJCOPY knob may be set 1616 to obtain the GNU version if necessary. 1617 161820160129: 1619 Building ZFS pools on top of zvols is prohibited by default. That 1620 feature has never worked safely; it's always been prone to deadlocks. 1621 Using a zvol as the backing store for a VM guest's virtual disk will 1622 still work, even if the guest is using ZFS. Legacy behavior can be 1623 restored by setting vfs.zfs.vol.recursive=1. 1624 162520160119: 1626 The NONE and HPN patches has been removed from OpenSSH. They are 1627 still available in the security/openssh-portable port. 1628 162920160113: 1630 With the addition of ypldap(8), a new _ypldap user is now required 1631 during installworld. "mergemaster -p" can be used to add the user 1632 prior to installworld, as documented in the handbook. 1633 163420151216: 1635 The tftp loader (pxeboot) now uses the option root-path directive. As a 1636 consequence it no longer looks for a pxeboot.4th file on the tftp 1637 server. Instead it uses the regular /boot infrastructure as with the 1638 other loaders. 1639 164020151211: 1641 The code to start recording plug and play data into the modules has 1642 been committed. While the old tools will properly build a new kernel, 1643 a number of warnings about "unknown metadata record 4" will be produced 1644 for an older kldxref. To avoid such warnings, make sure to rebuild 1645 the kernel toolchain (or world). Make sure that you have r292078 or 1646 later when trying to build 292077 or later before rebuilding. 1647 164820151207: 1649 Debug data files are now built by default with 'make buildworld' and 1650 installed with 'make installworld'. This facilitates debugging but 1651 requires more disk space both during the build and for the installed 1652 world. Debug files may be disabled by setting WITHOUT_DEBUG_FILES=yes 1653 in src.conf(5). 1654 165520151130: 1656 r291527 changed the internal interface between the nfsd.ko and 1657 nfscommon.ko modules. As such, they must both be upgraded to-gether. 1658 __FreeBSD_version has been bumped because of this. 1659 166020151108: 1661 Add support for unicode collation strings leads to a change of 1662 order of files listed by ls(1) for example. To get back to the old 1663 behaviour, set LC_COLLATE environment variable to "C". 1664 1665 Databases administrators will need to reindex their databases given 1666 collation results will be different. 1667 1668 Due to a bug in install(1) it is recommended to remove the ancient 1669 locales before running make installworld. 1670 1671 rm -rf /usr/share/locale/* 1672 167320151030: 1674 The OpenSSL has been upgraded to 1.0.2d. Any binaries requiring 1675 libcrypto.so.7 or libssl.so.7 must be recompiled. 1676 167720151020: 1678 Qlogic 24xx/25xx firmware images were updated from 5.5.0 to 7.3.0. 1679 Kernel modules isp_2400_multi and isp_2500_multi were removed and 1680 should be replaced with isp_2400 and isp_2500 modules respectively. 1681 168220151017: 1683 The build previously allowed using 'make -n' to not recurse into 1684 sub-directories while showing what commands would be executed, and 1685 'make -n -n' to recursively show commands. Now 'make -n' will recurse 1686 and 'make -N' will not. 1687 168820151012: 1689 If you specify SENDMAIL_MC or SENDMAIL_CF in make.conf, mergemaster 1690 and etcupdate will now use this file. A custom sendmail.cf is now 1691 updated via this mechanism rather than via installworld. If you had 1692 excluded sendmail.cf in mergemaster.rc or etcupdate.conf, you may 1693 want to remove the exclusion or change it to "always install". 1694 /etc/mail/sendmail.cf is now managed the same way regardless of 1695 whether SENDMAIL_MC/SENDMAIL_CF is used. If you are not using 1696 SENDMAIL_MC/SENDMAIL_CF there should be no change in behavior. 1697 169820151011: 1699 Compatibility shims for legacy ATA device names have been removed. 1700 It includes ATA_STATIC_ID kernel option, kern.cam.ada.legacy_aliases 1701 and kern.geom.raid.legacy_aliases loader tunables, kern.devalias.* 1702 environment variables, /dev/ad* and /dev/ar* symbolic links. 1703 170420151006: 1705 Clang, llvm, lldb, compiler-rt and libc++ have been upgraded to 3.7.0. 1706 Please see the 20141231 entry below for information about prerequisites 1707 and upgrading, if you are not already using clang 3.5.0 or higher. 1708 170920150924: 1710 Kernel debug files have been moved to /usr/lib/debug/boot/kernel/, 1711 and renamed from .symbols to .debug. This reduces the size requirements 1712 on the boot partition or file system and provides consistency with 1713 userland debug files. 1714 1715 When using the supported kernel installation method the 1716 /usr/lib/debug/boot/kernel directory will be renamed (to kernel.old) 1717 as is done with /boot/kernel. 1718 1719 Developers wishing to maintain the historical behavior of installing 1720 debug files in /boot/kernel/ can set KERN_DEBUGDIR="" in src.conf(5). 1721 172220150827: 1723 The wireless drivers had undergone changes that remove the 'parent 1724 interface' from the ifconfig -l output. The rc.d network scripts 1725 used to check presence of a parent interface in the list, so old 1726 scripts would fail to start wireless networking. Thus, etcupdate(3) 1727 or mergemaster(8) run is required after kernel update, to update your 1728 rc.d scripts in /etc. 1729 173020150827: 1731 pf no longer supports 'scrub fragment crop' or 'scrub fragment drop-ovl' 1732 These configurations are now automatically interpreted as 1733 'scrub fragment reassemble'. 1734 173520150817: 1736 Kernel-loadable modules for the random(4) device are back. To use 1737 them, the kernel must have 1738 1739 device random 1740 options RANDOM_LOADABLE 1741 1742 kldload(8) can then be used to load random_fortuna.ko 1743 or random_yarrow.ko. Please note that due to the indirect 1744 function calls that the loadable modules need to provide, 1745 the build-in variants will be slightly more efficient. 1746 1747 The random(4) kernel option RANDOM_DUMMY has been retired due to 1748 unpopularity. It was not all that useful anyway. 1749 175020150813: 1751 The WITHOUT_ELFTOOLCHAIN_TOOLS src.conf(5) knob has been retired. 1752 Control over building the ELF Tool Chain tools is now provided by 1753 the WITHOUT_TOOLCHAIN knob. 1754 175520150810: 1756 The polarity of Pulse Per Second (PPS) capture events with the 1757 uart(4) driver has been corrected. Prior to this change the PPS 1758 "assert" event corresponded to the trailing edge of a positive PPS 1759 pulse and the "clear" event was the leading edge of the next pulse. 1760 1761 As the width of a PPS pulse in a typical GPS receiver is on the 1762 order of 1 millisecond, most users will not notice any significant 1763 difference with this change. 1764 1765 Anyone who has compensated for the historical polarity reversal by 1766 configuring a negative offset equal to the pulse width will need to 1767 remove that workaround. 1768 176920150809: 1770 The default group assigned to /dev/dri entries has been changed 1771 from 'wheel' to 'video' with the id of '44'. If you want to have 1772 access to the dri devices please add yourself to the video group 1773 with: 1774 1775 # pw groupmod video -m $USER 1776 177720150806: 1778 The menu.rc and loader.rc files will now be replaced during 1779 upgrades. Please migrate local changes to menu.rc.local and 1780 loader.rc.local instead. 1781 178220150805: 1783 GNU Binutils versions of addr2line, c++filt, nm, readelf, size, 1784 strings and strip have been removed. The src.conf(5) knob 1785 WITHOUT_ELFTOOLCHAIN_TOOLS no longer provides the binutils tools. 1786 178720150728: 1788 As ZFS requires more kernel stack pages than is the default on some 1789 architectures e.g. i386, it now warns if KSTACK_PAGES is less than 1790 ZFS_MIN_KSTACK_PAGES (which is 4 at the time of writing). 1791 1792 Please consider using 'options KSTACK_PAGES=X' where X is greater 1793 than or equal to ZFS_MIN_KSTACK_PAGES i.e. 4 in such configurations. 1794 179520150706: 1796 sendmail has been updated to 8.15.2. Starting with FreeBSD 11.0 1797 and sendmail 8.15, sendmail uses uncompressed IPv6 addresses by 1798 default, i.e., they will not contain "::". For example, instead 1799 of ::1, it will be 0:0:0:0:0:0:0:1. This permits a zero subnet 1800 to have a more specific match, such as different map entries for 1801 IPv6:0:0 vs IPv6:0. This change requires that configuration 1802 data (including maps, files, classes, custom ruleset, etc.) must 1803 use the same format, so make certain such configuration data is 1804 upgrading. As a very simple check search for patterns like 1805 'IPv6:[0-9a-fA-F:]*::' and 'IPv6::'. To return to the old 1806 behavior, set the m4 option confUSE_COMPRESSED_IPV6_ADDRESSES or 1807 the cf option UseCompressedIPv6Addresses. 1808 180920150630: 1810 The default kernel entropy-processing algorithm is now 1811 Fortuna, replacing Yarrow. 1812 1813 Assuming you have 'device random' in your kernel config 1814 file, the configurations allow a kernel option to override 1815 this default. You may choose *ONE* of: 1816 1817 options RANDOM_YARROW # Legacy /dev/random algorithm. 1818 options RANDOM_DUMMY # Blocking-only driver. 1819 1820 If you have neither, you get Fortuna. For most people, 1821 read no further, Fortuna will give a /dev/random that works 1822 like it always used to, and the difference will be irrelevant. 1823 1824 If you remove 'device random', you get *NO* kernel-processed 1825 entropy at all. This may be acceptable to folks building 1826 embedded systems, but has complications. Carry on reading, 1827 and it is assumed you know what you need. 1828 1829 *PLEASE* read random(4) and random(9) if you are in the 1830 habit of tweaking kernel configs, and/or if you are a member 1831 of the embedded community, wanting specific and not-usual 1832 behaviour from your security subsystems. 1833 1834 NOTE!! If you use RANDOM_DUMMY and/or have no 'device 1835 random', you will NOT have a functioning /dev/random, and 1836 many cryptographic features will not work, including SSH. 1837 You may also find strange behaviour from the random(3) set 1838 of library functions, in particular sranddev(3), srandomdev(3) 1839 and arc4random(3). The reason for this is that the KERN_ARND 1840 sysctl only returns entropy if it thinks it has some to 1841 share, and with RANDOM_DUMMY or no 'device random' this 1842 will never happen. 1843 184420150623: 1845 An additional fix for the issue described in the 20150614 sendmail 1846 entry below has been committed in revision 284717. 1847 184820150616: 1849 FreeBSD's old make (fmake) has been removed from the system. It is 1850 available as the devel/fmake port or via pkg install fmake. 1851 185220150615: 1853 The fix for the issue described in the 20150614 sendmail entry 1854 below has been committed in revision 284436. The work 1855 around described in that entry is no longer needed unless the 1856 default setting is overridden by a confDH_PARAMETERS configuration 1857 setting of '5' or pointing to a 512 bit DH parameter file. 1858 185920150614: 1860 ALLOW_DEPRECATED_ATF_TOOLS/ATFFILE support has been removed from 1861 atf.test.mk (included from bsd.test.mk). Please upgrade devel/atf 1862 and devel/kyua to version 0.20+ and adjust any calling code to work 1863 with Kyuafile and kyua. 1864 186520150614: 1866 The import of openssl to address the FreeBSD-SA-15:10.openssl 1867 security advisory includes a change which rejects handshakes 1868 with DH parameters below 768 bits. sendmail releases prior 1869 to 8.15.2 (not yet released), defaulted to a 512 bit 1870 DH parameter setting for client connections. To work around 1871 this interoperability, sendmail can be configured to use a 1872 2048 bit DH parameter by: 1873 1874 1. Edit /etc/mail/`hostname`.mc 1875 2. If a setting for confDH_PARAMETERS does not exist or 1876 exists and is set to a string beginning with '5', 1877 replace it with '2'. 1878 3. If a setting for confDH_PARAMETERS exists and is set to 1879 a file path, create a new file with: 1880 openssl dhparam -out /path/to/file 2048 1881 4. Rebuild the .cf file: 1882 cd /etc/mail/; make; make install 1883 5. Restart sendmail: 1884 cd /etc/mail/; make restart 1885 1886 A sendmail patch is coming, at which time this file will be 1887 updated. 1888 188920150604: 1890 Generation of legacy formatted entries have been disabled by default 1891 in pwd_mkdb(8), as all base system consumers of the legacy formatted 1892 entries were converted to use the new format by default when the new, 1893 machine independent format have been added and supported since FreeBSD 1894 5.x. 1895 1896 Please see the pwd_mkdb(8) manual page for further details. 1897 189820150525: 1899 Clang and llvm have been upgraded to 3.6.1 release. Please see the 1900 20141231 entry below for information about prerequisites and upgrading, 1901 if you are not already using 3.5.0 or higher. 1902 190320150521: 1904 TI platform code switched to using vendor DTS files and this update 1905 may break existing systems running on Beaglebone, Beaglebone Black, 1906 and Pandaboard: 1907 1908 - dtb files should be regenerated/reinstalled. Filenames are the 1909 same but content is different now 1910 - GPIO addressing was changed, now each GPIO bank (32 pins per bank) 1911 has its own /dev/gpiocX device, e.g. pin 121 on /dev/gpioc0 in old 1912 addressing scheme is now pin 25 on /dev/gpioc3. 1913 - Pandaboard: /etc/ttys should be updated, serial console device is 1914 now /dev/ttyu2, not /dev/ttyu0 1915 191620150501: 1917 soelim(1) from gnu/usr.bin/groff has been replaced by usr.bin/soelim. 1918 If you need the GNU extension from groff soelim(1), install groff 1919 from package: pkg install groff, or via ports: textproc/groff. 1920 192120150423: 1922 chmod, chflags, chown and chgrp now affect symlinks in -R mode as 1923 defined in symlink(7); previously symlinks were silently ignored. 1924 192520150415: 1926 The const qualifier has been removed from iconv(3) to comply with 1927 POSIX. The ports tree is aware of this from r384038 onwards. 1928 192920150416: 1930 Libraries specified by LIBADD in Makefiles must have a corresponding 1931 DPADD_<lib> variable to ensure correct dependencies. This is now 1932 enforced in src.libnames.mk. 1933 193420150324: 1935 From legacy ata(4) driver was removed support for SATA controllers 1936 supported by more functional drivers ahci(4), siis(4) and mvs(4). 1937 Kernel modules ataahci and ataadaptec were removed completely, 1938 replaced by ahci and mvs modules respectively. 1939 194020150315: 1941 Clang, llvm and lldb have been upgraded to 3.6.0 release. Please see 1942 the 20141231 entry below for information about prerequisites and 1943 upgrading, if you are not already using 3.5.0 or higher. 1944 194520150307: 1946 The 32-bit PowerPC kernel has been changed to a position-independent 1947 executable. This can only be booted with a version of loader(8) 1948 newer than January 31, 2015, so make sure to update both world and 1949 kernel before rebooting. 1950 195120150217: 1952 If you are running a -CURRENT kernel since r273872 (Oct 30th, 2014), 1953 but before r278950, the RNG was not seeded properly. Immediately 1954 upgrade the kernel to r278950 or later and regenerate any keys (e.g. 1955 ssh keys or openssl keys) that were generated w/ a kernel from that 1956 range. This does not affect programs that directly used /dev/random 1957 or /dev/urandom. All userland uses of arc4random(3) are affected. 1958 195920150210: 1960 The autofs(4) ABI was changed in order to restore binary compatibility 1961 with 10.1-RELEASE. The automountd(8) daemon needs to be rebuilt to work 1962 with the new kernel. 1963 196420150131: 1965 The powerpc64 kernel has been changed to a position-independent 1966 executable. This can only be booted with a new version of loader(8), 1967 so make sure to update both world and kernel before rebooting. 1968 196920150118: 1970 Clang and llvm have been upgraded to 3.5.1 release. This is a bugfix 1971 only release, no new features have been added. Please see the 20141231 1972 entry below for information about prerequisites and upgrading, if you 1973 are not already using 3.5.0. 1974 197520150107: 1976 ELF tools addr2line, elfcopy (strip), nm, size, and strings are now 1977 taken from the ELF Tool Chain project rather than GNU binutils. They 1978 should be drop-in replacements, with the addition of arm64 support. 1979 The WITHOUT_ELFTOOLCHAIN_TOOLS= knob may be used to obtain the 1980 binutils tools, if necessary. See 20150805 for updated information. 1981 198220150105: 1983 The default Unbound configuration now enables remote control 1984 using a local socket. Users who have already enabled the 1985 local_unbound service should regenerate their configuration 1986 by running "service local_unbound setup" as root. 1987 198820150102: 1989 The GNU texinfo and GNU info pages have been removed. 1990 To be able to view GNU info pages please install texinfo from ports. 1991 199220141231: 1993 Clang, llvm and lldb have been upgraded to 3.5.0 release. 1994 1995 As of this release, a prerequisite for building clang, llvm and lldb is 1996 a C++11 capable compiler and C++11 standard library. This means that to 1997 be able to successfully build the cross-tools stage of buildworld, with 1998 clang as the bootstrap compiler, your system compiler or cross compiler 1999 should either be clang 3.3 or later, or gcc 4.8 or later, and your 2000 system C++ library should be libc++, or libdstdc++ from gcc 4.8 or 2001 later. 2002 2003 On any standard FreeBSD 10.x or 11.x installation, where clang and 2004 libc++ are on by default (that is, on x86 or arm), this should work out 2005 of the box. 2006 2007 On 9.x installations where clang is enabled by default, e.g. on x86 and 2008 powerpc, libc++ will not be enabled by default, so libc++ should be 2009 built (with clang) and installed first. If both clang and libc++ are 2010 missing, build clang first, then use it to build libc++. 2011 2012 On 8.x and earlier installations, upgrade to 9.x first, and then follow 2013 the instructions for 9.x above. 2014 2015 Sparc64 and mips users are unaffected, as they still use gcc 4.2.1 by 2016 default, and do not build clang. 2017 2018 Many embedded systems are resource constrained, and will not be able to 2019 build clang in a reasonable time, or in some cases at all. In those 2020 cases, cross building bootable systems on amd64 is a workaround. 2021 2022 This new version of clang introduces a number of new warnings, of which 2023 the following are most likely to appear: 2024 2025 -Wabsolute-value 2026 2027 This warns in two cases, for both C and C++: 2028 * When the code is trying to take the absolute value of an unsigned 2029 quantity, which is effectively a no-op, and almost never what was 2030 intended. The code should be fixed, if at all possible. If you are 2031 sure that the unsigned quantity can be safely cast to signed, without 2032 loss of information or undefined behavior, you can add an explicit 2033 cast, or disable the warning. 2034 2035 * When the code is trying to take an absolute value, but the called 2036 abs() variant is for the wrong type, which can lead to truncation. 2037 If you want to disable the warning instead of fixing the code, please 2038 make sure that truncation will not occur, or it might lead to unwanted 2039 side-effects. 2040 2041 -Wtautological-undefined-compare and 2042 -Wundefined-bool-conversion 2043 2044 These warn when C++ code is trying to compare 'this' against NULL, while 2045 'this' should never be NULL in well-defined C++ code. However, there is 2046 some legacy (pre C++11) code out there, which actively abuses this 2047 feature, which was less strictly defined in previous C++ versions. 2048 2049 Squid and openjdk do this, for example. The warning can be turned off 2050 for C++98 and earlier, but compiling the code in C++11 mode might result 2051 in unexpected behavior; for example, the parts of the program that are 2052 unreachable could be optimized away. 2053 205420141222: 2055 The old NFS client and server (kernel options NFSCLIENT, NFSSERVER) 2056 kernel sources have been removed. The .h files remain, since some 2057 utilities include them. This will need to be fixed later. 2058 If "mount -t oldnfs ..." is attempted, it will fail. 2059 If the "-o" option on mountd(8), nfsd(8) or nfsstat(1) is used, 2060 the utilities will report errors. 2061 206220141121: 2063 The handling of LOCAL_LIB_DIRS has been altered to skip addition of 2064 directories to top level SUBDIR variable when their parent 2065 directory is included in LOCAL_DIRS. Users with build systems with 2066 such hierarchies and without SUBDIR entries in the parent 2067 directory Makefiles should add them or add the directories to 2068 LOCAL_DIRS. 2069 207020141109: 2071 faith(4) and faithd(8) have been removed from the base system. Faith 2072 has been obsolete for a very long time. 2073 207420141104: 2075 vt(4), the new console driver, is enabled by default. It brings 2076 support for Unicode and double-width characters, as well as 2077 support for UEFI and integration with the KMS kernel video 2078 drivers. 2079 2080 You may need to update your console settings in /etc/rc.conf, 2081 most probably the keymap. During boot, /etc/rc.d/syscons will 2082 indicate what you need to do. 2083 2084 vt(4) still has issues and lacks some features compared to 2085 syscons(4). See the wiki for up-to-date information: 2086 https://wiki.freebsd.org/Newcons 2087 2088 If you want to keep using syscons(4), you can do so by adding 2089 the following line to /boot/loader.conf: 2090 kern.vty=sc 2091 209220141102: 2093 pjdfstest has been integrated into kyua as an opt-in test suite. 2094 Please see share/doc/pjdfstest/README for more details on how to 2095 execute it. 2096 209720141009: 2098 gperf has been removed from the base system for architectures 2099 that use clang. Ports that require gperf will obtain it from the 2100 devel/gperf port. 2101 210220140923: 2103 pjdfstest has been moved from tools/regression/pjdfstest to 2104 contrib/pjdfstest . 2105 210620140922: 2107 At svn r271982, The default linux compat kernel ABI has been adjusted 2108 to 2.6.18 in support of the linux-c6 compat ports infrastructure 2109 update. If you wish to continue using the linux-f10 compat ports, 2110 add compat.linux.osrelease=2.6.16 to your local sysctl.conf. Users are 2111 encouraged to update their linux-compat packages to linux-c6 during 2112 their next update cycle. 2113 211420140729: 2115 The ofwfb driver, used to provide a graphics console on PowerPC when 2116 using vt(4), no longer allows mmap() of all physical memory. This 2117 will prevent Xorg on PowerPC with some ATI graphics cards from 2118 initializing properly unless x11-servers/xorg-server is updated to 2119 1.12.4_8 or newer. 2120 212120140723: 2122 The xdev targets have been converted to using TARGET and 2123 TARGET_ARCH instead of XDEV and XDEV_ARCH. 2124 212520140719: 2126 The default unbound configuration has been modified to address 2127 issues with reverse lookups on networks that use private 2128 address ranges. If you use the local_unbound service, run 2129 "service local_unbound setup" as root to regenerate your 2130 configuration, then "service local_unbound reload" to load the 2131 new configuration. 2132 213320140709: 2134 The GNU texinfo and GNU info pages are not built and installed 2135 anymore, WITH_INFO knob has been added to allow to built and install 2136 them again. 2137 UPDATE: see 20150102 entry on texinfo's removal 2138 213920140708: 2140 The GNU readline library is now an INTERNALLIB - that is, it is 2141 statically linked into consumers (GDB and variants) in the base 2142 system, and the shared library is no longer installed. The 2143 devel/readline port is available for third party software that 2144 requires readline. 2145 214620140702: 2147 The Itanium architecture (ia64) has been removed from the list of 2148 known architectures. This is the first step in the removal of the 2149 architecture. 2150 215120140701: 2152 Commit r268115 has added NFSv4.1 server support, merged from 2153 projects/nfsv4.1-server. Since this includes changes to the 2154 internal interfaces between the NFS related modules, a full 2155 build of the kernel and modules will be necessary. 2156 __FreeBSD_version has been bumped. 2157 215820140629: 2159 The WITHOUT_VT_SUPPORT kernel config knob has been renamed 2160 WITHOUT_VT. (The other _SUPPORT knobs have a consistent meaning 2161 which differs from the behaviour controlled by this knob.) 2162 216320140619: 2164 Maximal length of the serial number in CTL was increased from 16 to 2165 64 chars, that breaks ABI. All CTL-related tools, such as ctladm 2166 and ctld, need to be rebuilt to work with a new kernel. 2167 216820140606: 2169 The libatf-c and libatf-c++ major versions were downgraded to 0 and 2170 1 respectively to match the upstream numbers. They were out of 2171 sync because, when they were originally added to FreeBSD, the 2172 upstream versions were not respected. These libraries are private 2173 and not yet built by default, so renumbering them should be a 2174 non-issue. However, unclean source trees will yield broken test 2175 programs once the operator executes "make delete-old-libs" after a 2176 "make installworld". 2177 2178 Additionally, the atf-sh binary was made private by moving it into 2179 /usr/libexec/. Already-built shell test programs will keep the 2180 path to the old binary so they will break after "make delete-old" 2181 is run. 2182 2183 If you are using WITH_TESTS=yes (not the default), wipe the object 2184 tree and rebuild from scratch to prevent spurious test failures. 2185 This is only needed once: the misnumbered libraries and misplaced 2186 binaries have been added to OptionalObsoleteFiles.inc so they will 2187 be removed during a clean upgrade. 2188 218920140512: 2190 Clang and llvm have been upgraded to 3.4.1 release. 2191 219220140508: 2193 We bogusly installed src.opts.mk in /usr/share/mk. This file should 2194 be removed to avoid issues in the future (and has been added to 2195 ObsoleteFiles.inc). 2196 219720140505: 2198 /etc/src.conf now affects only builds of the FreeBSD src tree. In the 2199 past, it affected all builds that used the bsd.*.mk files. The old 2200 behavior was a bug, but people may have relied upon it. To get this 2201 behavior back, you can .include /etc/src.conf from /etc/make.conf 2202 (which is still global and isn't changed). This also changes the 2203 behavior of incremental builds inside the tree of individual 2204 directories. Set MAKESYSPATH to ".../share/mk" to do that. 2205 Although this has survived make universe and some upgrade scenarios, 2206 other upgrade scenarios may have broken. At least one form of 2207 temporary breakage was fixed with MAKESYSPATH settings for buildworld 2208 as well... In cases where MAKESYSPATH isn't working with this 2209 setting, you'll need to set it to the full path to your tree. 2210 2211 One side effect of all this cleaning up is that bsd.compiler.mk 2212 is no longer implicitly included by bsd.own.mk. If you wish to 2213 use COMPILER_TYPE, you must now explicitly include bsd.compiler.mk 2214 as well. 2215 221620140430: 2217 The lindev device has been removed since /dev/full has been made a 2218 standard device. __FreeBSD_version has been bumped. 2219 222020140424: 2221 The knob WITHOUT_VI was added to the base system, which controls 2222 building ex(1), vi(1), etc. Older releases of FreeBSD required ex(1) 2223 in order to reorder files share/termcap and didn't build ex(1) as a 2224 build tool, so building/installing with WITH_VI is highly advised for 2225 build hosts for older releases. 2226 2227 This issue has been fixed in stable/9 and stable/10 in r277022 and 2228 r276991, respectively. 2229 223020140418: 2231 The YES_HESIOD knob has been removed. It has been obsolete for 2232 a decade. Please move to using WITH_HESIOD instead or your builds 2233 will silently lack HESIOD. 2234 223520140405: 2236 The uart(4) driver has been changed with respect to its handling 2237 of the low-level console. Previously the uart(4) driver prevented 2238 any process from changing the baudrate or the CLOCAL and HUPCL 2239 control flags. By removing the restrictions, operators can make 2240 changes to the serial console port without having to reboot. 2241 However, when getty(8) is started on the serial device that is 2242 associated with the low-level console, a misconfigured terminal 2243 line in /etc/ttys will now have a real impact. 2244 Before upgrading the kernel, make sure that /etc/ttys has the 2245 serial console device configured as 3wire without baudrate to 2246 preserve the previous behaviour. E.g: 2247 ttyu0 "/usr/libexec/getty 3wire" vt100 on secure 2248 224920140306: 2250 Support for libwrap (TCP wrappers) in rpcbind was disabled by default 2251 to improve performance. To re-enable it, if needed, run rpcbind 2252 with command line option -W. 2253 225420140226: 2255 Switched back to the GPL dtc compiler due to updates in the upstream 2256 dts files not being supported by the BSDL dtc compiler. You will need 2257 to rebuild your kernel toolchain to pick up the new compiler. Core dumps 2258 may result while building dtb files during a kernel build if you fail 2259 to do so. Set WITHOUT_GPL_DTC if you require the BSDL compiler. 2260 226120140216: 2262 Clang and llvm have been upgraded to 3.4 release. 2263 226420140216: 2265 The nve(4) driver has been removed. Please use the nfe(4) driver 2266 for NVIDIA nForce MCP Ethernet adapters instead. 2267 226820140212: 2269 An ABI incompatibility crept into the libc++ 3.4 import in r261283. 2270 This could cause certain C++ applications using shared libraries built 2271 against the previous version of libc++ to crash. The incompatibility 2272 has now been fixed, but any C++ applications or shared libraries built 2273 between r261283 and r261801 should be recompiled. 2274 227520140204: 2276 OpenSSH will now ignore errors caused by kernel lacking of Capsicum 2277 capability mode support. Please note that enabling the feature in 2278 kernel is still highly recommended. 2279 228020140131: 2281 OpenSSH is now built with sandbox support, and will use sandbox as 2282 the default privilege separation method. This requires Capsicum 2283 capability mode support in kernel. 2284 228520140128: 2286 The libelf and libdwarf libraries have been updated to newer 2287 versions from upstream. Shared library version numbers for 2288 these two libraries were bumped. Any ports or binaries 2289 requiring these two libraries should be recompiled. 2290 __FreeBSD_version is bumped to 1100006. 2291 229220140110: 2293 If a Makefile in a tests/ directory was auto-generating a Kyuafile 2294 instead of providing an explicit one, this would prevent such 2295 Makefile from providing its own Kyuafile in the future during 2296 NO_CLEAN builds. This has been fixed in the Makefiles but manual 2297 intervention is needed to clean an objdir if you use NO_CLEAN: 2298 # find /usr/obj -name Kyuafile | xargs rm -f 2299 230020131213: 2301 The behavior of gss_pseudo_random() for the krb5 mechanism 2302 has changed, for applications requesting a longer random string 2303 than produced by the underlying enctype's pseudo-random() function. 2304 In particular, the random string produced from a session key of 2305 enctype aes256-cts-hmac-sha1-96 or aes256-cts-hmac-sha1-96 will 2306 be different at the 17th octet and later, after this change. 2307 The counter used in the PRF+ construction is now encoded as a 2308 big-endian integer in accordance with RFC 4402. 2309 __FreeBSD_version is bumped to 1100004. 2310 231120131108: 2312 The WITHOUT_ATF build knob has been removed and its functionality 2313 has been subsumed into the more generic WITHOUT_TESTS. If you were 2314 using the former to disable the build of the ATF libraries, you 2315 should change your settings to use the latter. 2316 231720131025: 2318 The default version of mtree is nmtree which is obtained from 2319 NetBSD. The output is generally the same, but may vary 2320 slightly. If you found you need identical output adding 2321 "-F freebsd9" to the command line should do the trick. For the 2322 time being, the old mtree is available as fmtree. 2323 232420131014: 2325 libbsdyml has been renamed to libyaml and moved to /usr/lib/private. 2326 This will break ports-mgmt/pkg. Rebuild the port, or upgrade to pkg 2327 1.1.4_8 and verify bsdyml not linked in, before running "make 2328 delete-old-libs": 2329 # make -C /usr/ports/ports-mgmt/pkg build deinstall install clean 2330 or 2331 # pkg install pkg; ldd /usr/local/sbin/pkg | grep bsdyml 2332 233320131010: 2334 The stable/10 branch has been created in subversion from head 2335 revision r256279. 2336 2337COMMON ITEMS: 2338 2339 General Notes 2340 ------------- 2341 Sometimes, obscure build problems are the result of environment 2342 poisoning. This can happen because the make utility reads its 2343 environment when searching for values for global variables. To run 2344 your build attempts in an "environmental clean room", prefix all make 2345 commands with 'env -i '. See the env(1) manual page for more details. 2346 Occasionally a build failure will occur with "make -j" due to a race 2347 condition. If this happens try building again without -j, and please 2348 report a bug if it happens consistently. 2349 2350 When upgrading from one major version to another it is generally best to 2351 upgrade to the latest code in the currently installed branch first, then 2352 do an upgrade to the new branch. This is the best-tested upgrade path, 2353 and has the highest probability of being successful. Please try this 2354 approach if you encounter problems with a major version upgrade. Since 2355 the stable 4.x branch point, one has generally been able to upgrade from 2356 anywhere in the most recent stable branch to head / current (or even the 2357 last couple of stable branches). See the top of this file when there's 2358 an exception. 2359 2360 The update process will emit an error on an attempt to perform a build 2361 or install from a FreeBSD version below the earliest supported version. 2362 When updating from an older version the update should be performed one 2363 major release at a time, including running `make delete-old` at each 2364 step. 2365 2366 When upgrading a live system, having a root shell around before 2367 installing anything can help undo problems. Not having a root shell 2368 around can lead to problems if pam has changed too much from your 2369 starting point to allow continued authentication after the upgrade. 2370 2371 This file should be read as a log of events. When a later event changes 2372 information of a prior event, the prior event should not be deleted. 2373 Instead, a pointer to the entry with the new information should be 2374 placed in the old entry. Readers of this file should also sanity check 2375 older entries before relying on them blindly. Authors of new entries 2376 should write them with this in mind. 2377 2378 ZFS notes 2379 --------- 2380 When upgrading the boot ZFS pool to a new version, always follow 2381 these two steps: 2382 2383 1.) recompile and reinstall the ZFS boot loader and boot block 2384 (this is part of "make buildworld" and "make installworld") 2385 2386 2.) update the ZFS boot block on your boot drive 2387 2388 The following example updates the ZFS boot block on the 2389 freebsd-boot partition of a GPT partitioned drive ada0: 2390 "gpart bootcode -p /boot/gptzfsboot -i $N ada0" 2391 The value $N will typically be 1 (if booting from BIOS) or 2 (if 2392 booting from EFI). 2393 2394 Non-boot pools do not need these updates. 2395 2396 To build a kernel 2397 ----------------- 2398 If you are updating from a prior version of FreeBSD (even one just 2399 a few days old), you should follow this procedure. It is the most 2400 failsafe as it uses a /usr/obj tree with a fresh mini-buildworld, 2401 2402 make kernel-toolchain 2403 make -DALWAYS_CHECK_MAKE buildkernel KERNCONF=YOUR_KERNEL_HERE 2404 make -DALWAYS_CHECK_MAKE installkernel KERNCONF=YOUR_KERNEL_HERE 2405 2406 To test a kernel once 2407 --------------------- 2408 If you just want to boot a kernel once (because you are not sure 2409 if it works, or if you want to boot a known bad kernel to provide 2410 debugging information) run 2411 make installkernel KERNCONF=YOUR_KERNEL_HERE KODIR=/boot/testkernel 2412 nextboot -k testkernel 2413 2414 To rebuild everything and install it on the current system. 2415 ----------------------------------------------------------- 2416 # Note: sometimes if you are running current you gotta do more than 2417 # is listed here if you are upgrading from a really old current. 2418 2419 <make sure you have good level 0 dumps> 2420 make buildworld 2421 make buildkernel KERNCONF=YOUR_KERNEL_HERE 2422 make installkernel KERNCONF=YOUR_KERNEL_HERE 2423 [1] 2424 <reboot in single user> [3] 2425 mergemaster -Fp [5] 2426 make installworld 2427 mergemaster -Fi [4] 2428 make delete-old [6] 2429 <reboot> 2430 2431 To cross-install current onto a separate partition 2432 -------------------------------------------------- 2433 # In this approach we use a separate partition to hold 2434 # current's root, 'usr', and 'var' directories. A partition 2435 # holding "/", "/usr" and "/var" should be about 2GB in 2436 # size. 2437 2438 <make sure you have good level 0 dumps> 2439 <boot into -stable> 2440 make buildworld 2441 make buildkernel KERNCONF=YOUR_KERNEL_HERE 2442 <maybe newfs current's root partition> 2443 <mount current's root partition on directory ${CURRENT_ROOT}> 2444 make installworld DESTDIR=${CURRENT_ROOT} -DDB_FROM_SRC 2445 make distribution DESTDIR=${CURRENT_ROOT} # if newfs'd 2446 make installkernel KERNCONF=YOUR_KERNEL_HERE DESTDIR=${CURRENT_ROOT} 2447 cp /etc/fstab ${CURRENT_ROOT}/etc/fstab # if newfs'd 2448 <edit ${CURRENT_ROOT}/etc/fstab to mount "/" from the correct partition> 2449 <reboot into current> 2450 <do a "native" rebuild/install as described in the previous section> 2451 <maybe install compatibility libraries from ports/misc/compat*> 2452 <reboot> 2453 2454 2455 To upgrade in-place from stable to current 2456 ---------------------------------------------- 2457 <make sure you have good level 0 dumps> 2458 make buildworld [9] 2459 make buildkernel KERNCONF=YOUR_KERNEL_HERE [8] 2460 make installkernel KERNCONF=YOUR_KERNEL_HERE 2461 [1] 2462 <reboot in single user> [3] 2463 mergemaster -Fp [5] 2464 make installworld 2465 mergemaster -Fi [4] 2466 make delete-old [6] 2467 <reboot> 2468 2469 Make sure that you've read the UPDATING file to understand the 2470 tweaks to various things you need. At this point in the life 2471 cycle of current, things change often and you are on your own 2472 to cope. The defaults can also change, so please read ALL of 2473 the UPDATING entries. 2474 2475 Also, if you are tracking -current, you must be subscribed to 2476 freebsd-current@freebsd.org. Make sure that before you update 2477 your sources that you have read and understood all the recent 2478 messages there. If in doubt, please track -stable which has 2479 much fewer pitfalls. 2480 2481 [1] If you have third party modules, such as vmware, you should disable 2482 them at this point so they don't crash your system on 2483 reboot. Alternatively, you should rebuild all the modules you have in 2484 your system and install them as well. If you are running -current, you 2485 should seriously consider placing all sources to all the modules for 2486 your system (or symlinks to them) in /usr/local/sys/modules so this 2487 happens automatically. If all your modules come from ports, then adding 2488 the port origin directories to PORTS_MODULES instead is also automatic 2489 and effective, eg: 2490 PORTS_MODULES+=x11/nvidia-driver 2491 2492 [3] From the bootblocks, boot -s, and then do 2493 fsck -p 2494 mount -u / 2495 mount -a 2496 sh /etc/rc.d/zfs start # mount zfs filesystem, if needed 2497 cd src # full path to source 2498 adjkerntz -i # if CMOS is wall time 2499 Also, when doing a major release upgrade, it is required that you boot 2500 into single user mode to do the installworld. 2501 2502 [4] Note: This step is non-optional. Failure to do this step 2503 can result in a significant reduction in the functionality of the 2504 system. Attempting to do it by hand is not recommended and those 2505 that pursue this avenue should read this file carefully, as well 2506 as the archives of freebsd-current and freebsd-hackers mailing lists 2507 for potential gotchas. The -U option is also useful to consider. 2508 See mergemaster(8) for more information. 2509 2510 [5] Usually this step is a no-op. However, from time to time 2511 you may need to do this if you get unknown user in the following 2512 step. It never hurts to do it all the time. You may need to 2513 install a new mergemaster (cd src/usr.sbin/mergemaster && make 2514 install) after the buildworld before this step if you last updated 2515 from current before 20130425 or from -stable before 20130430. 2516 2517 [6] This only deletes old files and directories. Old libraries 2518 can be deleted by "make delete-old-libs", but you have to make 2519 sure that no program is using those libraries anymore. 2520 2521 [8] The new kernel must be able to run existing binaries used by an 2522 installworld. When upgrading across major versions, the new kernel's 2523 configuration must include the correct COMPAT_FREEBSD<n> option for 2524 existing binaries (e.g. COMPAT_FREEBSD11 to run 11.x binaries). Failure 2525 to do so may leave you with a system that is hard to boot to recover. A 2526 GENERIC kernel will include suitable compatibility options to run 2527 binaries from older branches. Note that the ability to run binaries 2528 from unsupported branches is not guaranteed. 2529 2530 Make sure that you merge any new devices from GENERIC since the 2531 last time you updated your kernel config file. Options also 2532 change over time, so you may need to adjust your custom kernels 2533 for these as well. 2534 2535 [9] If CPUTYPE is defined in your /etc/make.conf, make sure to use the 2536 "?=" instead of the "=" assignment operator, so that buildworld can 2537 override the CPUTYPE if it needs to. 2538 2539 MAKEOBJDIRPREFIX must be defined in an environment variable, and 2540 not on the command line, or in /etc/make.conf. buildworld will 2541 warn if it is improperly defined. 2542FORMAT: 2543 2544This file contains a list, in reverse chronological order, of major 2545breakages in tracking -current. It is not guaranteed to be a complete 2546list of such breakages, and only contains entries since September 23, 2011. 2547If you need to see UPDATING entries from before that date, you will need 2548to fetch an UPDATING file from an older FreeBSD release. 2549 2550Copyright information: 2551 2552Copyright 1998-2009 M.
