1 Updating Information for FreeBSD stable/12 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://www.freebsd.org/doc/en_US.ISO8859-1/books/handbook/makeworld.html 10 11Items affecting the ports and packages system can be found in 12/usr/ports/UPDATING. Please read that file before updating system packages 13and/or ports. 14 15NOTE: FreeBSD has switched from gcc to clang. If you have trouble bootstrapping 16from older versions of FreeBSD, try WITHOUT_CLANG and WITH_GCC to bootstrap to 17the tip of head, and then rebuild without this option. The bootstrap process 18from older version of current across the gcc/clang cutover is a bit fragile. 19 2020210510: 21 Commit e9959506d2cc changed the internal KAPI between the 22 nscl.ko and nfscommon.ko modules, so they both need to be 23 rebuilt from sources. 24 2520210430: 26 Commit 0a1fdb867c72 changed the internal KAPI between 27 the krpc and NFS. As such, the krpc, nfscommon and 28 nfscl modules must all be rebuilt from sources. 29 Without this patch, NFSv4.1 mounts should not 30 be done with the nfscbd(8) daemon running, to avoid 31 needing a working back channel for server->client RPCs. 32 3320200912: 34 The make.conf(5) MALLOC_PRODUCTION variable, used for disabling and 35 enabling assertions and statistics gathering in malloc(3), has been 36 migrated to a src.conf(5) WITH/WITHOUT_MALLOC_PRODUCTION option. 37 38 On stable branches, WITH_MALLOC_PRODUCTION is set by default, which 39 means that malloc(3) has assertions and statistics gathering disabled, 40 for improved performance. 41 42 For backwards compatibility, the make.conf(5) MALLOC_PRODUCTION is still 43 honored, but it is now deprecated and undocumented. 44 4520200909: 46 The resume code now notifies devd with the 'kernel' system 47 rather than the old 'kern' subsystem to be consistent with 48 other use. The old notification will be created as well, but 49 will be removed prior to FreeBSD 14.0. 50 5120200722: 52 Clang, llvm, lld, lldb, compiler-rt, libc++, libunwind and openmp have 53 been upgraded to 10.0.1. Please see the 20141231 entry below for 54 information about prerequisites and upgrading, if you are not already 55 using clang 3.5.0 or higher. 56 5720200708: 58 read(2) of a directory fd is now rejected by default. root may 59 re-enable it for the entire system with the 60 security.bsd.allow_read_dir sysctl(8) MIB. 61 62 It may be advised to setup aliases for grep to default to `-d skip` if 63 commonly non-recursively grepping a list that includes directories and 64 the potential for the resulting stderr output is not tolerable. Example 65 aliases are now installed, commented out, in /root/.cshrc. 66 6720200414: 68 Upstream DTS from Linux 5.6 was merged and they now have the SID 69 and THS (Secure ID controller and THermal Sensor) node present. 70 The DTB overlays have now been removed from the tree for the H3/H5 and 71 A64 SoCs and the aw_sid and aw_thermal driver have been updated to 72 deal with upstream DTS. If you are using those overlays you need to 73 remove them from loader.conf and update the DTBs on the FAT partition. 74 7520200501: 76 Clang, llvm, lld, lldb, compiler-rt, libc++, libunwind and openmp have 77 been upgraded to 10.0.0. Please see the 20141231 entry below for 78 information about prerequisites and upgrading, if you are not already 79 using clang 3.5.0 or higher. 80 8120200430: 82 The root certificates of the Mozilla CA Certificate Store have been 83 imported into the base system and can be managed with the certctl(8) 84 utility. If you have installed the security/ca_root_nss port or package 85 with the ETCSYMLINK option (the default), be advised that there may be 86 differences between those included in the port and those included in 87 base due to differences in nss branch used as well as general update 88 frequency. Note also that certctl(8) cannot manage certs in the 89 format used by the security/ca_root_nss port. 90 9120200107: 92 Clang, llvm, lld, lldb, compiler-rt, libc++, libunwind and openmp have 93 been upgraded to 9.0.1. Please see the 20141231 entry below for 94 information about prerequisites and upgrading, if you are not already 95 using clang 3.5.0 or higher. 96 9720191107: 98 The nctgpio and wbwd drivers have been moved to the superio bus. 99 If you have one of these drivers in a kernel configuration, then 100 you should add device superio to it. If you use one of these drivers 101 as a module and you compile a custom set of modules, then you should 102 add superio to the set. 103 10420191024: 105 The tap(4) driver has been folded into tun(4), and the module has been 106 renamed to tuntap. You should update any kld_list="if_tap" or 107 kld_list="if_tun" entries in /etc/rc.conf, if_tap_load="YES" or 108 if_tun_load="YES" entries in /boot/loader.conf to load the if_tuntap 109 module instead, and "device tap" or "device tun" entries in kernel 110 config files to select the tuntap device instead. 111 11220190913: 113 ntpd no longer by default locks its pages in memory, allowing them 114 to be paged out by the kernel. Use rlimit memlock to restore 115 historic BSD behaviour. For example, add "rlimit memlock 32" 116 to ntp.conf to lock up to 32 MB of ntpd address space in memory. 117 11820190914: 119 The vfs.fusefs.sync_unmount and vfs.fusefs.init_backgrounded sysctls 120 and the "-o sync_unmount" and "-o init_backgrounded" mount options have 121 been removed from mount_fusefs(8). You can safely remove them from 122 your scripts, because they had no effect. 123 124 The vfs.fusefs.fix_broken_io, vfs.fusefs.sync_resize, 125 vfs.fusefs.refresh_size, vfs.fusefs.mmap_enable, 126 vfs.fusefs.reclaim_revoked, and vfs.fusefs.data_cache_invalidate 127 sysctls have been removed. If you felt the need to set any of them to 128 a non-default value, please tell asomers@FreeBSD.org why. 129 13020190906: 131 The fuse(4) module has been renamed to fusefs(4) for consistency with 132 other filesystems. You should update any kld_load="fuse" entries in 133 /etc/rc.conf, fuse_load="YES" entries in /boot/loader.conf, and 134 "options FUSE" enties in kernel config files. 135 13620190811: 137 Default permissions on the /var/account/acct file (and copies of it 138 rotated by periodic daily scripts) are changed from 0644 to 0640 139 because the file contains sensitive information that should not be 140 world-readable. If the /var/account directory must be created by 141 rc.d/accounting, the mode used is now 0750. Admins who use the 142 accounting feature are encouraged to change the mode of an existing 143 /var/account directory to 0750 or 0700. 144 14520190723: 146 Clang, llvm, lld, lldb, compiler-rt, libc++, libunwind and openmp have 147 been upgraded to 8.0.1. Please see the 20141231 entry below for 148 information about prerequisites and upgrading, if you are not already 149 using clang 3.5.0 or higher. 150 15120190413: 152 Now Clang 8 has been merged (see the 20190412 entry below), the ifunc 153 functionality needed for the RETPOLINE option should work properly 154 again. The RETPOLINE option has been removed from BROKEN_OPTIONS. 155 15620190412: 157 Clang, llvm, lld, lldb, compiler-rt and libc++ have been upgraded to 158 8.0.0. Please see the 20141231 entry below for information about 159 prerequisites and upgrading, if you are not already using clang 3.5.0 160 or higher. 161 16220190307: 163 The RETPOLINE option produces non-functional ifunc-using binaries 164 with Clang 7.0.1, and has been forced off (via BROKEN_OPTIONS). 165 Once Clang 8 is merged it may be enabled again. 166 16720190216: 168 Clang, llvm, lld, lldb, compiler-rt and libc++ have been upgraded to 169 7.0.1. Please see the 20141231 entry below for information about 170 prerequisites and upgrading, if you are not already using clang 3.5.0 171 or higher. 172 17320190226: 174 geom_uzip(4) depends on the new module xz. If geom_uzip is statically 175 compiled into your custom kernel, add 'device xz' statement to the 176 kernel config. 177 17820190214: 179 Iflib is no longer unconditionally compiled into the kernel. Drivers 180 using iflib and statically compiled into the kernel, now require 181 the 'device iflib' config option. For the same drivers loaded as 182 modules on kernels not having 'device iflib', the iflib.ko module 183 is loaded automatically. 184 18520181228: 186 r342561 modifies the NFSv4 server so that it obeys vfs.nfsd.nfs_privport 187 in the same as it is applied to NFSv2 and 3. This implies that NFSv4 188 servers that have vfs.nfsd.nfs_privport set will only allow mounts 189 from clients using a reserved port#. Since both the FreeBSD and Linux 190 NFSv4 clients use reserved port#s by default, this should not affect 191 most NFSv4 mounts. 192 19320181129: 194 On amd64, arm64 and armv7 (architectures that install LLVM's ld.lld 195 linker as /usr/bin/ld) GNU ld is no longer installed as ld.bfd, as 196 it produces broken binaries when ifuncs are in use. Users needing 197 GNU ld should install the binutils port or package. 198 19920181115: 200 The set of CTM commands (ctm, ctm_smail, ctm_rmail, ctm_dequeue) 201 has been converted to a port (misc/ctm) and will be removed from 202 FreeBSD-13. A depreciation warning will be printed to stderr by 203 the ctm command, but the functionality will remain in base for all 204 FreeBSD-12 releases. 205 20620181019: 207 The stable/12 branch has been created in subversion from head 208 revision r339432. 209 21020181015: 211 Ports for the DRM modules have been simplified. Now, amd64 users should 212 just install the drm-kmod port. All others should install 213 drm-legacy-kmod. 214 215 Graphics hardware that's newer than about 2010 usually works with 216 drm-kmod. For hardware older than 2013, however, some users will need 217 to use drm-legacy-kmod if drm-kmod doesn't work for them. Hardware older 218 than 2008 usually only works in drm-legacy-kmod. The graphics team can 219 only commit to hardware made since 2013 due to the complexity of the 220 market and difficulty to test all the older cards effectively. If you 221 have hardware supported by drm-kmod, you are strongly encouraged to use 222 that as you will get better support. 223 224 Other than KPI chasing, drm-legacy-kmod will not be updated. As outlined 225 elsewhere, the drm and drm2 modules will be eliminated from the src base 226 soon (with a limited exception for arm). Please update to the package asap 227 and report any issues to x11@freebsd.org. 228 229 Generally, anybody using the drm*-kmod packages should add 230 WITHOUT_DRM_MODULE=t and WITHOUT_DRM2_MODULE=t to avoid nasty 231 cross-threading surprises, especially with automatic driver 232 loading from X11 startup. These will become the defaults in 13-current 233 shortly. 234 23520181012: 236 The ixlv(4) driver has been renamed to iavf(4). As a consequence, 237 custom kernel and module loading configuration files must be updated 238 accordingly. Moreover, interfaces previous presented as ixlvN to the 239 system are now exposed as iavfN and network configuration files must 240 be adjusted as necessary. 241 24220181009: 243 OpenSSL has been updated to version 1.1.1. This update included 244 additional various API changes througout the base system. It is 245 important to rebuild third-party software after upgrading. The value 246 of __FreeBSD_version has been bumped accordingly. 247 24820181006: 249 The legacy DRM modules and drivers have now been added to the loader's 250 module blacklist, in favor of loading them with kld_list in rc.conf(5). 251 The module blacklist may be overridden with the loader.conf(5) 252 'module_blacklist' variable, but loading them via rc.conf(5) is strongly 253 encouraged. 254 25520181002: 256 The cam(4) based nda(4) driver will be used over nvd(4) by default on 257 powerpc64. You may set 'options NVME_USE_NVD=1' in your kernel conf or 258 loader tunable 'hw.nvme.use_nvd=1' if you wish to use the existing 259 driver. Make sure to edit /boot/etc/kboot.conf and fstab to use the 260 nda device name. 261 26220180913: 263 Reproducible build mode is now on by default, in preparation for 264 FreeBSD 12.0. This eliminates build metadata such as the user, 265 host, and time from the kernel (and uname), unless the working tree 266 corresponds to a modified checkout from a version control system. 267 The previous behavior can be obtained by setting the /etc/src.conf 268 knob WITHOUT_REPRODUCIBLE_BUILD. 269 27020180826: 271 The Yarrow CSPRNG has been removed from the kernel as it has not been 272 supported by its designers since at least 2003. Fortuna has been the 273 default since FreeBSD-11. 274 27520180822: 276 devctl freeze/thaw have gone into the tree, the rc scripts have been 277 updated to use them and devmatch has been changed. You should update 278 kernel, userland and rc scripts all at the same time. 279 28020180818: 281 The default interpreter has been switched from 4th to Lua. 282 LOADER_DEFAULT_INTERP, documented in build(7), will override the default 283 interpreter. If you have custom FORTH code you will need to set 284 LOADER_DEFAULT_INTERP=4th (valid values are 4th, lua or simp) in 285 src.conf for the build. This will create default hard links between 286 loader and loader_4th instead of loader and loader_lua, the new default. 287 If you are using UEFI it will create the proper hard link to loader.efi. 288 289 bhyve uses userboot.so. It remains 4th-only until some issues are solved 290 regarding coexisting with multiple versions of FreeBSD are resolved. 291 29220180815: 293 ls(1) now respects the COLORTERM environment variable used in other 294 systems and software to indicate that a colored terminal is both 295 supported and desired. If ls(1) is suddenly emitting colors, they may 296 be disabled again by either removing the unwanted COLORTERM from your 297 environment, or using `ls --color=never`. The ls(1) specific CLICOLOR 298 may not be observed in a future release. 299 30020180808: 301 The default pager for most commands has been changed to "less". To 302 restore the old behavior, set PAGER="more" and MANPAGER="more -s" in 303 your environment. 304 30520180731: 306 The jedec_ts(4) driver has been removed. A superset of its functionality 307 is available in the jedec_dimm(4) driver, and the manpage for that 308 driver includes migration instructions. If you have "device jedec_ts" 309 in your kernel configuration file, it must be removed. 310 31120180730: 312 amd64/GENERIC now has EFI runtime services, EFIRT, enabled by default. 313 This should have no effect if the kernel is booted via BIOS/legacy boot. 314 EFIRT may be disabled via a loader tunable, efi.rt.disabled, if a system 315 has a buggy firmware that prevents a successful boot due to use of 316 runtime services. 317 31820180727: 319 Atmel AT91RM9200 and AT91SAM9, Cavium CNS 11xx and XScale 320 support has been removed from the tree. These ports were 321 obsolete and/or known to be broken for many years. 322 32320180723: 324 loader.efi has been augmented to participate more fully in the 325 UEFI boot manager protocol. loader.efi will now look at the 326 BootXXXX environment variable to determine if a specific kernel 327 or root partition was specified. XXXX is derived from BootCurrent. 328 efibootmgr(8) manages these standard UEFI variables. 329 33020180720: 331 zfsloader's functionality has now been folded into loader. 332 zfsloader is no longer necessary once you've updated your 333 boot blocks. For a transition period, we will install a 334 hardlink for zfsloader to loader to allow a smooth transition 335 until the boot blocks can be updated (hard link because old 336 zfs boot blocks don't understand symlinks). 337 33820180719: 339 ARM64 now have efifb support, if you want to have serial console 340 on your arm64 board when an screen is connected and the bootloader 341 setup a frambuffer for us to use, just add : 342 boot_serial=YES 343 boot_multicons=YES 344 in /boot/loader.conf 345 For Raspberry Pi 3 (RPI) users, this is needed even if you don't have 346 an screen connected as the firmware will setup a framebuffer are that 347 u-boot will expose as an EFI framebuffer. 348 34920180719: 350 New uid:gid added, ntpd:ntpd (123:123). Be sure to run mergemaster 351 or take steps to update /etc/passwd before doing installworld on 352 existing systems. Do not skip the "mergemaster -Fp" step before 353 installworld, as described in the update procedures near the bottom 354 of this document. Also, rc.d/ntpd now starts ntpd(8) as user ntpd 355 if the new mac_ntpd(4) policy is available, unless ntpd_flags or 356 the ntp config file contain options that change file/dir locations. 357 When such options (e.g., "statsdir" or "crypto") are used, ntpd can 358 still be run as non-root by setting ntpd_user=ntpd in rc.conf, after 359 taking steps to ensure that all required files/dirs are accessible 360 by the ntpd user. 361 36220180717: 363 Big endian arm support has been removed. 364 36520180711: 366 The static environment setup in kernel configs is no longer mutually 367 exclusive with the loader(8) environment by default. In order to 368 restore the previous default behavior of disabling the loader(8) 369 environment if a static environment is present, you must specify 370 loader_env.disabled=1 in the static environment. 371 37220180705: 373 The ABI of syscalls used by management tools like sockstat and 374 netstat has been broken to allow 32-bit binaries to work on 375 64-bit kernels without modification. These programs will need 376 to match the kernel in order to function. External programs may 377 require minor modifications to accommodate a change of type in 378 structures from pointers to 64-bit virtual addresses. 379 38020180702: 381 On i386 and amd64 atomics are now inlined. Out of tree modules using 382 atomics will need to be rebuilt. 383 38420180701: 385 The '%I' format in the kern.corefile sysctl limits the number of 386 core files that a process can generate to the number stored in the 387 debug.ncores sysctl. The '%I' format is replaced by the single digit 388 index. Previously, if all indexes were taken the kernel would overwrite 389 only a core file with the highest index in a filename. 390 Currently the system will create a new core file if there is a free 391 index or if all slots are taken it will overwrite the oldest one. 392 39320180630: 394 Clang, llvm, lld, lldb, compiler-rt and libc++ have been upgraded to 395 6.0.1. Please see the 20141231 entry below for information about 396 prerequisites and upgrading, if you are not already using clang 3.5.0 397 or higher. 398 39920180628: 400 r335753 introduced a new quoting method. However, etc/devd/devmatch.conf 401 needed to be changed to work with it. This change was made with r335763 402 and requires a mergemaster / etcupdate / etc to update the installed file. 403 40420180612: 405 r334930 changed the interface between the NFS modules, so they all 406 need to be rebuilt. r335018 did a __FreeBSD_version bump for this. 407 40820180530: 409 As of r334391 lld is the default amd64 system linker; it is installed 410 as /usr/bin/ld. Kernel build workarounds (see 20180510 entry) are no 411 longer necessary. 412 41320180530: 414 The kernel / userland interface for devinfo changed, so you'll 415 need a new kernel and userland as a pair for it to work (rebuilding 416 lib/libdevinfo is all that's required). devinfo and devmatch will 417 not work, but everything else will when there's a mismatch. 418 41920180523: 420 The on-disk format for hwpmc callchain records has changed to include 421 threadid corresponding to a given record. This changes the field offsets 422 and thus requires that libpmcstat be rebuilt before using a kernel 423 later than r334108. 424 42520180517: 426 The vxge(4) driver has been removed. This driver was introduced into 427 HEAD one week before the Exar left the Ethernet market and is not 428 known to be used. If you have device vxge in your kernel config file 429 it must be removed. 430 43120180510: 432 The amd64 kernel now requires a ld that supports ifunc to produce a 433 working kernel, either lld or a newer binutils. lld is built by default 434 on amd64, and the 'buildkernel' target uses it automatically. However, 435 it is not the default linker, so building the kernel the traditional 436 way requires LD=ld.lld on the command line (or LD=/usr/local/bin/ld for 437 binutils port/package). lld will soon be default, and this requirement 438 will go away. 439 440 NOTE: As of r334391 lld is the default system linker on amd64, and no 441 workaround is necessary. 442 44320180508: 444 The nxge(4) driver has been removed. This driver was for PCI-X 10g 445 cards made by s2io/Neterion. The company was aquired by Exar and 446 no longer sells or supports Ethernet products. If you have device 447 nxge in your kernel config file it must be removed. 448 44920180504: 450 The tz database (tzdb) has been updated to 2018e. This version more 451 correctly models time stamps in time zones with negative DST such as 452 Europe/Dublin (from 1971 on), Europe/Prague (1946/7), and 453 Africa/Windhoek (1994/2017). This does not affect the UT offsets, only 454 time zone abbreviations and the tm_isdst flag. 455 45620180502: 457 The ixgb(4) driver has been removed. This driver was for an early and 458 uncommon legacy PCI 10GbE for a single ASIC, Intel 82597EX. Intel 459 quickly shifted to the long lived ixgbe family. If you have device 460 ixgb in your kernel config file it must be removed. 461 46220180501: 463 The lmc(4) driver has been removed. This was a WAN interface 464 card that was already reportedly rare in 2003, and had an ambiguous 465 license. If you have device lmc in your kernel config file it must 466 be removed. 467 46820180413: 469 Support for Arcnet networks has been removed. If you have device 470 arcnet or device cm in your kernel config file they must be 471 removed. 472 47320180411: 474 Support for FDDI networks has been removed. If you have device 475 fddi or device fpa in your kernel config file they must be 476 removed. 477 47820180406: 479 In addition to supporting RFC 3164 formatted messages, the 480 syslogd(8) service is now capable of parsing RFC 5424 formatted 481 log messages. The main benefit of using RFC 5424 is that clients 482 may now send log messages with timestamps containing year numbers, 483 microseconds and time zone offsets. 484 485 Similarly, the syslog(3) C library function has been altered to 486 send RFC 5424 formatted messages to the local system logging 487 daemon. On systems using syslogd(8), this change should have no 488 negative impact, as long as syslogd(8) and the C library are 489 updated at the same time. On systems using a different system 490 logging daemon, it may be necessary to make configuration 491 adjustments, depending on the software used. 492 493 When using syslog-ng, add the 'syslog-protocol' flag to local 494 input sources to enable parsing of RFC 5424 formatted messages: 495 496 source src { 497 unix-dgram("/var/run/log" flags(syslog-protocol)); 498 } 499 500 When using rsyslog, disable the 'SysSock.UseSpecialParser' option 501 of the 'imuxsock' module to let messages be processed by the 502 regular RFC 3164/5424 parsing pipeline: 503 504 module(load="imuxsock" SysSock.UseSpecialParser="off") 505 506 Do note that these changes only affect communication between local 507 applications and syslogd(8). The format that syslogd(8) uses to 508 store messages on disk or forward messages to other systems 509 remains unchanged. syslogd(8) still uses RFC 3164 for these 510 purposes. Options to customize this behaviour will be added in the 511 future. Utilities that process log files stored in /var/log are 512 thus expected to continue to function as before. 513 514 __FreeBSD_version has been incremented to 1200061 to denote this 515 change. 516 51720180328: 518 Support for token ring networks has been removed. If you 519 have "device token" in your kernel config you should remove 520 it. No device drivers supported token ring. 521 52220180323: 523 makefs was modified to be able to tag ISO9660 El Torito boot catalog 524 entries as EFI instead of overloading the i386 tag as done previously. 525 The amd64 mkisoimages.sh script used to build amd64 ISO images for 526 release was updated to use this. This may mean that makefs must be 527 updated before "make cdrom" can be run in the release directory. This 528 should be as simple as: 529 530 $ cd $SRCDIR/usr.sbin/makefs 531 $ make depend all install 532 53320180212: 534 FreeBSD boot loader enhanced with Lua scripting. It's purely opt-in for 535 now by building WITH_LOADER_LUA and WITHOUT_FORTH in /etc/src.conf. 536 Co-existance for the transition period will come shortly. Booting is a 537 complex environment and test coverage for Lua-enabled loaders has been 538 thin, so it would be prudent to assume it might not work and make 539 provisions for backup boot methods. 540 54120180211: 542 devmatch functionality has been turned on in devd. It will automatically 543 load drivers for unattached devices. This may cause unexpected drivers to 544 be loaded. Please report any problems to current@ and imp@freebsd.org. 545 54620180114: 547 Clang, llvm, lld, lldb, compiler-rt and libc++ have been upgraded to 548 6.0.0. Please see the 20141231 entry below for information about 549 prerequisites and upgrading, if you are not already using clang 3.5.0 550 or higher. 551 55220180110: 553 LLVM's lld linker is now used as the FreeBSD/amd64 bootstrap linker. 554 This means it is used to link the kernel and userland libraries and 555 executables, but is not yet installed as /usr/bin/ld by default. 556 557 To revert to ld.bfd as the bootstrap linker, in /etc/src.conf set 558 WITHOUT_LLD_BOOTSTRAP=yes 559 56020180110: 561 On i386, pmtimer has been removed. Its functionality has been folded 562 into apm. It was a no-op on ACPI in current for a while now (but was still 563 needed on i386 in FreeBSD 11 and earlier). Users may need to remove it 564 from kernel config files. 565 56620180104: 567 The use of RSS hash from the network card aka flowid has been 568 disabled by default for lagg(4) as it's currently incompatible with 569 the lacp and loadbalance protocols. 570 571 This can be re-enabled by setting the following in loader.conf: 572 net.link.lagg.default_use_flowid="1" 573 57420180102: 575 The SW_WATCHDOG option is no longer necessary to enable the 576 hardclock-based software watchdog if no hardware watchdog is 577 configured. As before, SW_WATCHDOG will cause the software 578 watchdog to be enabled even if a hardware watchdog is configured. 579 58020171215: 581 r326887 fixes the issue described in the 20171214 UPDATING entry. 582 r326888 flips the switch back to building GELI support always. 583 58420171214: 585 r362593 broke ZFS + GELI support for reasons unknown. However, 586 it also broke ZFS support generally, so GELI has been turned off 587 by default as the lesser evil in r326857. If you boot off ZFS and/or 588 GELI, it might not be a good time to update. 589 59020171125: 591 PowerPC users must update loader(8) by rebuilding world before 592 installing a new kernel, as the protocol connecting them has 593 changed. Without the update, loader metadata will not be passed 594 successfully to the kernel and users will have to enter their 595 root partition at the kernel mountroot prompt to continue booting. 596 Newer versions of loader can boot old kernels without issue. 597 59820171110: 599 The LOADER_FIREWIRE_SUPPORT build variable as been renamed to 600 WITH/OUT_LOADER_FIREWIRE. LOADER_{NO_,}GELI_SUPPORT has been renamed 601 to WITH/OUT_LOADER_GELI. 602 60320171106: 604 The naive and non-compliant support of posix_fallocate(2) in ZFS 605 has been removed as of r325320. The system call now returns EINVAL 606 when used on a ZFS file. Although the new behavior complies with the 607 standard, some consumers are not prepared to cope with it. 608 One known victim is lld prior to r325420. 609 61020171102: 611 Building in a FreeBSD src checkout will automatically create object 612 directories now rather than store files in the current directory if 613 'make obj' was not ran. Calling 'make obj' is no longer necessary. 614 This feature can be disabled by setting WITHOUT_AUTO_OBJ=yes in 615 /etc/src-env.conf (not /etc/src.conf), or passing the option in the 616 environment. 617 61820171101: 619 The default MAKEOBJDIR has changed from /usr/obj/<srcdir> for native 620 builds, and /usr/obj/<arch>/<srcdir> for cross-builds, to a unified 621 /usr/obj/<srcdir>/<arch>. This behavior can be changed to the old 622 format by setting WITHOUT_UNIFIED_OBJDIR=yes in /etc/src-env.conf, 623 the environment, or with -DWITHOUT_UNIFIED_OBJDIR when building. 624 The UNIFIED_OBJDIR option is a transitional feature that will be 625 removed for 12.0 release; please migrate to the new format for any 626 tools by looking up the OBJDIR used by 'make -V .OBJDIR' means rather 627 than hardcoding paths. 628 62920171028: 630 The native-xtools target no longer installs the files by default to the 631 OBJDIR. Use the native-xtools-install target with a DESTDIR to install 632 to ${DESTDIR}/${NXTP} where NXTP defaults to /nxb-bin. 633 63420171021: 635 As part of the boot loader infrastructure cleanup, LOADER_*_SUPPORT 636 options are changing from controlling the build if defined / undefined 637 to controlling the build with explicit 'yes' or 'no' values. They will 638 shift to WITH/WITHOUT options to match other options in the system. 639 64020171010: 641 libstand has turned into a private library for sys/boot use only. 642 It is no longer supported as a public interface outside of sys/boot. 643 64420171005: 645 The arm port has split armv6 into armv6 and armv7. armv7 is now 646 a valid TARGET_ARCH/MACHINE_ARCH setting. If you have an armv7 system 647 and are running a kernel from before r324363, you will need to add 648 MACHINE_ARCH=armv7 to 'make buildworld' to do a native build. 649 65020171003: 651 When building multiple kernels using KERNCONF, non-existent KERNCONF 652 files will produce an error and buildkernel will fail. Previously 653 missing KERNCONF files silently failed giving no indication as to 654 why, only to subsequently discover during installkernel that the 655 desired kernel was never built in the first place. 656 65720170912: 658 The default serial number format for CTL LUNs has changed. This will 659 affect users who use /dev/diskid/* device nodes, or whose FibreChannel 660 or iSCSI clients care about their LUNs' serial numbers. Users who 661 require serial number stability should hardcode serial numbers in 662 /etc/ctl.conf . 663 66420170912: 665 For 32-bit arm compiled for hard-float support, soft-floating point 666 binaries now always get their shared libraries from 667 LD_SOFT_LIBRARY_PATH (in the past, this was only used if 668 /usr/libsoft also existed). Only users with a hard-float ld.so, but 669 soft-float everything else should be affected. 670 67120170826: 672 The geli password typed at boot is now hidden. To restore the previous 673 behavior, see geli(8) for configuration options. 674 67520170825: 676 Move PMTUD blackhole counters to TCPSTATS and remove them from bare 677 sysctl values. Minor nit, but requires a rebuild of both world/kernel 678 to complete. 679 68020170814: 681 "make check" behavior (made in ^/head@r295380) has been changed to 682 execute from a limited sandbox, as opposed to executing from 683 ${TESTSDIR}. 684 685 Behavioral changes: 686 - The "beforecheck" and "aftercheck" targets are now specified. 687 - ${CHECKDIR} (added in commit noted above) has been removed. 688 - Legacy behavior can be enabled by setting 689 WITHOUT_MAKE_CHECK_USE_SANDBOX in src.conf(5) or the environment. 690 691 If the limited sandbox mode is enabled, "make check" will execute 692 "make distribution", then install, execute the tests, and clean up the 693 sandbox if successful. 694 695 The "make distribution" and "make install" targets are typically run as 696 root to set appropriate permissions and ownership at installation time. 697 The end-user should set "WITH_INSTALL_AS_USER" in src.conf(5) or the 698 environment if executing "make check" with limited sandbox mode using 699 an unprivileged user. 700 70120170808: 702 Since the switch to GPT disk labels, fsck for UFS/FFS has been 703 unable to automatically find alternate superblocks. As of r322297, 704 the information needed to find alternate superblocks has been 705 moved to the end of the area reserved for the boot block. 706 Filesystems created with a newfs of this vintage or later 707 will create the recovery information. If you have a filesystem 708 created prior to this change and wish to have a recovery block 709 created for your filesystem, you can do so by running fsck in 710 foreground mode (i.e., do not use the -p or -y options). As it 711 starts, fsck will ask ``SAVE DATA TO FIND ALTERNATE SUPERBLOCKS'' 712 to which you should answer yes. 713 71420170728: 715 As of r321665, an NFSv4 server configuration that services 716 Kerberos mounts or clients that do not support the uid/gid in 717 owner/owner_group string capability, must explicitly enable 718 the nfsuserd daemon by adding nfsuserd_enable="YES" to the 719 machine's /etc/rc.conf file. 720 72120170722: 722 Clang, llvm, lldb, compiler-rt and libc++ have been upgraded to 5.0.0. 723 Please see the 20141231 entry below for information about prerequisites 724 and upgrading, if you are not already using clang 3.5.0 or higher. 725 72620170701: 727 WITHOUT_RCMDS is now the default. Set WITH_RCMDS if you need the 728 r-commands (rlogin, rsh, etc.) to be built with the base system. 729 73020170625: 731 The FreeBSD/powerpc platform now uses a 64-bit type for time_t. This is 732 a very major ABI incompatible change, so users of FreeBSD/powerpc must 733 be careful when performing source upgrades. It is best to run 734 'make installworld' from an alternate root system, either a live 735 CD/memory stick, or a temporary root partition. Additionally, all ports 736 must be recompiled. powerpc64 is largely unaffected, except in the case 737 of 32-bit compatibility. All 32-bit binaries will be affected. 738 73920170623: 740 Forward compatibility for the "ino64" project have been committed. This 741 will allow most new binaries to run on older kernels in a limited 742 fashion. This prevents many of the common foot-shooting actions in the 743 upgrade as well as the limited ability to roll back the kernel across 744 the ino64 upgrade. Complicated use cases may not work properly, though 745 enough simpler ones work to allow recovery in most situations. 746 74720170620: 748 Switch back to the BSDL dtc (Device Tree Compiler). Set WITH_GPL_DTC 749 if you require the GPL compiler. 750 75120170618: 752 The internal ABI used for communication between the NFS kernel modules 753 was changed by r320085, so __FreeBSD_version was bumped to 754 ensure all the NFS related modules are updated together. 755 75620170617: 757 The ABI of struct event was changed by extending the data 758 member to 64bit and adding ext fields. For upgrade, same 759 precautions as for the entry 20170523 "ino64" must be 760 followed. 761 76220170531: 763 The GNU roff toolchain has been removed from base. To render manpages 764 which are not supported by mandoc(1), man(1) can fallback on GNU roff 765 from ports (and recommends to install it). 766 To render roff(7) documents, consider using GNU roff from ports or the 767 heirloom doctools roff toolchain from ports via pkg install groff or 768 via pkg install heirloom-doctools. 769 77020170524: 771 The ath(4) and ath_hal(4) modules now build piecemeal to allow for 772 smaller runtime footprint builds. This is useful for embedded systems 773 which only require one chipset support. 774 775 If you load it as a module, make sure this is in /boot/loader.conf: 776 777 if_ath_load="YES" 778 779 This will load the HAL, all chip/RF backends and if_ath_pci. 780 If you have if_ath_pci in /boot/loader.conf, ensure it is after 781 if_ath or it will not load any HAL chipset support. 782 783 If you want to selectively load things (eg on ye cheape ARM/MIPS 784 platforms where RAM is at a premium) you should: 785 786 * load ath_hal 787 * load the chip modules in question 788 * load ath_rate, ath_dfs 789 * load ath_main 790 * load if_ath_pci and/or if_ath_ahb depending upon your particular 791 bus bind type - this is where probe/attach is done. 792 793 For further comments/feedback, poke adrian@ . 794 79520170523: 796 The "ino64" 64-bit inode project has been committed, which extends 797 a number of types to 64 bits. Upgrading in place requires care and 798 adherence to the documented upgrade procedure. 799 800 If using a custom kernel configuration ensure that the 801 COMPAT_FREEBSD11 option is included (as during the upgrade the 802 system will be running the ino64 kernel with the existing world). 803 804 For the safest in-place upgrade begin by removing previous build 805 artifacts via "rm -rf /usr/obj/*". Then, carefully follow the 806 full procedure documented below under the heading "To rebuild 807 everything and install it on the current system." Specifically, 808 a reboot is required after installing the new kernel before 809 installing world. 810 81120170424: 812 The NATM framework including the en(4), fatm(4), hatm(4), and 813 patm(4) devices has been removed. Consumers should plan a 814 migration before the end-of-life date for FreeBSD 11. 815 81620170420: 817 GNU diff has been replaced by a BSD licensed diff. Some features of GNU 818 diff has not been implemented, if those are needed a newer version of 819 GNU diff is available via the diffutils package under the gdiff name. 820 82120170413: 822 As of r316810 for ipfilter, keep frags is no longer assumed when 823 keep state is specified in a rule. r316810 aligns ipfilter with 824 documentation in man pages separating keep frags from keep state. 825 This allows keep state to be specified without forcing keep frags 826 and allows keep frags to be specified independently of keep state. 827 To maintain previous behaviour, also specify keep frags with 828 keep state (as documented in ipf.conf.5). 829 83020170407: 831 arm64 builds now use the base system LLD 4.0.0 linker by default, 832 instead of requiring that the aarch64-binutils port or package be 833 installed. To continue using aarch64-binutils, set 834 CROSS_BINUTILS_PREFIX=/usr/local/aarch64-freebsd/bin . 835 83620170405: 837 The UDP optimization in entry 20160818 that added the sysctl 838 net.inet.udp.require_l2_bcast has been reverted. L2 broadcast 839 packets will no longer be treated as L3 broadcast packets. 840 84120170331: 842 Binds and sends to the loopback addresses, IPv6 and IPv4, will now 843 use any explicitly assigned loopback address available in the jail 844 instead of using the first assigned address of the jail. 845 84620170329: 847 The ctl.ko module no longer implements the iSCSI target frontend: 848 cfiscsi.ko does instead. 849 850 If building cfiscsi.ko as a kernel module, the module can be loaded 851 via one of the following methods: 852 - `cfiscsi_load="YES"` in loader.conf(5). 853 - Add `cfiscsi` to `$kld_list` in rc.conf(5). 854 - ctladm(8)/ctld(8), when compiled with iSCSI support 855 (`WITH_ISCSI=yes` in src.conf(5)) 856 857 Please see cfiscsi(4) for more details. 858 85920170316: 860 The mmcsd.ko module now additionally depends on geom_flashmap.ko. 861 Also, mmc.ko and mmcsd.ko need to be a matching pair built from the 862 same source (previously, the dependency of mmcsd.ko on mmc.ko was 863 missing, but mmcsd.ko now will refuse to load if it is incompatible 864 with mmc.ko). 865 86620170315: 867 The syntax of ipfw(8) named states was changed to avoid ambiguity. 868 If you have used named states in the firewall rules, you need to modify 869 them after installworld and before rebooting. Now named states must 870 be prefixed with colon. 871 87220170311: 873 The old drm (sys/dev/drm/) drivers for i915 and radeon have been 874 removed as the userland we provide cannot use them. The KMS version 875 (sys/dev/drm2) supports the same hardware. 876 87720170302: 878 Clang, llvm, lldb, compiler-rt and libc++ have been upgraded to 4.0.0. 879 Please see the 20141231 entry below for information about prerequisites 880 and upgrading, if you are not already using clang 3.5.0 or higher. 881 88220170221: 883 The code that provides support for ZFS .zfs/ directory functionality 884 has been reimplemented. It's not possible now to create a snapshot 885 by mkdir under .zfs/snapshot/. That should be the only user visible 886 change. 887 88820170216: 889 EISA bus support has been removed. The WITH_EISA option is no longer 890 valid. 891 89220170215: 893 MCA bus support has been removed. 894 89520170127: 896 The WITH_LLD_AS_LD / WITHOUT_LLD_AS_LD build knobs have been renamed 897 WITH_LLD_IS_LD / WITHOUT_LLD_IS_LD, for consistency with CLANG_IS_CC. 898 89920170112: 900 The EM_MULTIQUEUE kernel configuration option is deprecated now that 901 the em(4) driver conforms to iflib specifications. 902 90320170109: 904 The igb(4), em(4) and lem(4) ethernet drivers are now implemented via 905 IFLIB. If you have a custom kernel configuration that excludes em(4) 906 but you use igb(4), you need to re-add em(4) to your custom configuration. 907 90820161217: 909 Clang, llvm, lldb, compiler-rt and libc++ have been upgraded to 3.9.1. 910 Please see the 20141231 entry below for information about prerequisites 911 and upgrading, if you are not already using clang 3.5.0 or higher. 912 91320161124: 914 Clang, llvm, lldb, compiler-rt and libc++ have been upgraded to 3.9.0. 915 Please see the 20141231 entry below for information about prerequisites 916 and upgrading, if you are not already using clang 3.5.0 or higher. 917 91820161119: 919 The layout of the pmap structure has changed for powerpc to put the pmap 920 statistics at the front for all CPU variations. libkvm(3) and all tools 921 that link against it need to be recompiled. 922 92320161030: 924 isl(4) and cyapa(4) drivers now require a new driver, 925 chromebook_platform(4), to work properly on Chromebook-class hardware. 926 On other types of hardware the drivers may need to be configured using 927 device hints. Please see the corresponding manual pages for details. 928 92920161017: 930 The urtwn(4) driver was merged into rtwn(4) and now consists of 931 rtwn(4) main module + rtwn_usb(4) and rtwn_pci(4) bus-specific 932 parts. 933 Also, firmware for RTL8188CE was renamed due to possible name 934 conflict (rtwnrtl8192cU(B) -> rtwnrtl8192cE(B)) 935 93620161015: 937 GNU rcs has been removed from base. It is available as packages: 938 - rcs: Latest GPLv3 GNU rcs version. 939 - rcs57: Copy of the latest version of GNU rcs (GPLv2) before it was 940 removed from base. 941 94220161008: 943 Use of the cc_cdg, cc_chd, cc_hd, or cc_vegas congestion control 944 modules now requires that the kernel configuration contain the 945 TCP_HHOOK option. (This option is included in the GENERIC kernel.) 946 94720161003: 948 The WITHOUT_ELFCOPY_AS_OBJCOPY src.conf(5) knob has been retired. 949 ELF Tool Chain's elfcopy is always installed as /usr/bin/objcopy. 950 95120160924: 952 Relocatable object files with the extension of .So have been renamed 953 to use an extension of .pico instead. The purpose of this change is 954 to avoid a name clash with shared libraries on case-insensitive file 955 systems. On those file systems, foo.So is the same file as foo.so. 956 95720160918: 958 GNU rcs has been turned off by default. It can (temporarily) be built 959 again by adding WITH_RCS knob in src.conf. 960 Otherwise, GNU rcs is available from packages: 961 - rcs: Latest GPLv3 GNU rcs version. 962 - rcs57: Copy of the latest version of GNU rcs (GPLv2) from base. 963 96420160918: 965 The backup_uses_rcs functionality has been removed from rc.subr. 966 96720160908: 968 The queue(3) debugging macro, QUEUE_MACRO_DEBUG, has been split into 969 two separate components, QUEUE_MACRO_DEBUG_TRACE and 970 QUEUE_MACRO_DEBUG_TRASH. Define both for the original 971 QUEUE_MACRO_DEBUG behavior. 972 97320160824: 974 r304787 changed some ioctl interfaces between the iSCSI userspace 975 programs and the kernel. ctladm, ctld, iscsictl, and iscsid must be 976 rebuilt to work with new kernels. __FreeBSD_version has been bumped 977 to 1200005. 978 97920160818: 980 The UDP receive code has been updated to only treat incoming UDP 981 packets that were addressed to an L2 broadcast address as L3 982 broadcast packets. It is not expected that this will affect any 983 standards-conforming UDP application. The new behaviour can be 984 disabled by setting the sysctl net.inet.udp.require_l2_bcast to 985 0. 986 98720160818: 988 Remove the openbsd_poll system call. 989 __FreeBSD_version has been bumped because of this. 990 99120160708: 992 The stable/11 branch has been created from head@r302406. 993 99420160622: 995 The libc stub for the pipe(2) system call has been replaced with 996 a wrapper that calls the pipe2(2) system call and the pipe(2) 997 system call is now only implemented by the kernels that include 998 "options COMPAT_FREEBSD10" in their config file (this is the 999 default). Users should ensure that this option is enabled in 1000 their kernel or upgrade userspace to r302092 before upgrading their 1001 kernel. 1002 100320160527: 1004 CAM will now strip leading spaces from SCSI disks' serial numbers. 1005 This will affect users who create UFS filesystems on SCSI disks using 1006 those disk's diskid device nodes. For example, if /etc/fstab 1007 previously contained a line like 1008 "/dev/diskid/DISK-%20%20%20%20%20%20%20ABCDEFG0123456", you should 1009 change it to "/dev/diskid/DISK-ABCDEFG0123456". Users of geom 1010 transforms like gmirror may also be affected. ZFS users should 1011 generally be fine. 1012 101320160523: 1014 The bitstring(3) API has been updated with new functionality and 1015 improved performance. But it is binary-incompatible with the old API. 1016 Objects built with the new headers may not be linked against objects 1017 built with the old headers. 1018 101920160520: 1020 The brk and sbrk functions have been removed from libc on arm64. 1021 Binutils from ports has been updated to not link to these 1022 functions and should be updated to the latest version before 1023 installing a new libc. 1024 102520160517: 1026 The armv6 port now defaults to hard float ABI. Limited support 1027 for running both hardfloat and soft float on the same system 1028 is available using the libraries installed with -DWITH_LIBSOFT. 1029 This has only been tested as an upgrade path for installworld 1030 and packages may fail or need manual intervention to run. New 1031 packages will be needed. 1032 1033 To update an existing self-hosted armv6hf system, you must add 1034 TARGET_ARCH=armv6 on the make command line for both the build 1035 and the install steps. 1036 103720160510: 1038 Kernel modules compiled outside of a kernel build now default to 1039 installing to /boot/modules instead of /boot/kernel. Many kernel 1040 modules built this way (such as those in ports) already overrode 1041 KMODDIR explicitly to install into /boot/modules. However, 1042 manually building and installing a module from /sys/modules will 1043 now install to /boot/modules instead of /boot/kernel. 1044 104520160414: 1046 The CAM I/O scheduler has been committed to the kernel. There should be 1047 no user visible impact. This does enable NCQ Trim on ada SSDs. While the 1048 list of known rogues that claim support for this but actually corrupt 1049 data is believed to be complete, be on the lookout for data 1050 corruption. The known rogue list is believed to be complete: 1051 1052 o Crucial MX100, M550 drives with MU01 firmware. 1053 o Micron M510 and M550 drives with MU01 firmware. 1054 o Micron M500 prior to MU07 firmware 1055 o Samsung 830, 840, and 850 all firmwares 1056 o FCCT M500 all firmwares 1057 1058 Crucial has firmware http://www.crucial.com/usa/en/support-ssd-firmware 1059 with working NCQ TRIM. For Micron branded drives, see your sales rep for 1060 updated firmware. Black listed drives will work correctly because these 1061 drives work correctly so long as no NCQ TRIMs are sent to them. Given 1062 this list is the same as found in Linux, it's believed there are no 1063 other rogues in the market place. All other models from the above 1064 vendors work. 1065 1066 To be safe, if you are at all concerned, you can quirk each of your 1067 drives to prevent NCQ from being sent by setting: 1068 kern.cam.ada.X.quirks="0x2" 1069 in loader.conf. If the drive requires the 4k sector quirk, set the 1070 quirks entry to 0x3. 1071 107220160330: 1073 The FAST_DEPEND build option has been removed and its functionality is 1074 now the one true way. The old mkdep(1) style of 'make depend' has 1075 been removed. See 20160311 for further details. 1076 107720160317: 1078 Resource range types have grown from unsigned long to uintmax_t. All 1079 drivers, and anything using libdevinfo, need to be recompiled. 1080 108120160311: 1082 WITH_FAST_DEPEND is now enabled by default for in-tree and out-of-tree 1083 builds. It no longer runs mkdep(1) during 'make depend', and the 1084 'make depend' stage can safely be skipped now as it is auto ran 1085 when building 'make all' and will generate all SRCS and DPSRCS before 1086 building anything else. Dependencies are gathered at compile time with 1087 -MF flags kept in separate .depend files per object file. Users should 1088 run 'make cleandepend' once if using -DNO_CLEAN to clean out older 1089 stale .depend files. 1090 109120160306: 1092 On amd64, clang 3.8.0 can now insert sections of type AMD64_UNWIND into 1093 kernel modules. Therefore, if you load any kernel modules at boot time, 1094 please install the boot loaders after you install the kernel, but before 1095 rebooting, e.g.: 1096 1097 make buildworld 1098 make buildkernel KERNCONF=YOUR_KERNEL_HERE 1099 make installkernel KERNCONF=YOUR_KERNEL_HERE 1100 make -C sys/boot install 1101 <reboot in single user> 1102 1103 Then follow the usual steps, described in the General Notes section, 1104 below. 1105 110620160305: 1107 Clang, llvm, lldb and compiler-rt have been upgraded to 3.8.0. Please 1108 see the 20141231 entry below for information about prerequisites and 1109 upgrading, if you are not already using clang 3.5.0 or higher. 1110 111120160301: 1112 The AIO subsystem is now a standard part of the kernel. The 1113 VFS_AIO kernel option and aio.ko kernel module have been removed. 1114 Due to stability concerns, asynchronous I/O requests are only 1115 permitted on sockets and raw disks by default. To enable 1116 asynchronous I/O requests on all file types, set the 1117 vfs.aio.enable_unsafe sysctl to a non-zero value. 1118 111920160226: 1120 The ELF object manipulation tool objcopy is now provided by the 1121 ELF Tool Chain project rather than by GNU binutils. It should be a 1122 drop-in replacement, with the addition of arm64 support. The 1123 (temporary) src.conf knob WITHOUT_ELFCOPY_AS_OBJCOPY knob may be set 1124 to obtain the GNU version if necessary. 1125 112620160129: 1127 Building ZFS pools on top of zvols is prohibited by default. That 1128 feature has never worked safely; it's always been prone to deadlocks. 1129 Using a zvol as the backing store for a VM guest's virtual disk will 1130 still work, even if the guest is using ZFS. Legacy behavior can be 1131 restored by setting vfs.zfs.vol.recursive=1. 1132 113320160119: 1134 The NONE and HPN patches has been removed from OpenSSH. They are 1135 still available in the security/openssh-portable port. 1136 113720160113: 1138 With the addition of ypldap(8), a new _ypldap user is now required 1139 during installworld. "mergemaster -p" can be used to add the user 1140 prior to installworld, as documented in the handbook. 1141 114220151216: 1143 The tftp loader (pxeboot) now uses the option root-path directive. As a 1144 consequence it no longer looks for a pxeboot.4th file on the tftp 1145 server. Instead it uses the regular /boot infrastructure as with the 1146 other loaders. 1147 114820151211: 1149 The code to start recording plug and play data into the modules has 1150 been committed. While the old tools will properly build a new kernel, 1151 a number of warnings about "unknown metadata record 4" will be produced 1152 for an older kldxref. To avoid such warnings, make sure to rebuild 1153 the kernel toolchain (or world). Make sure that you have r292078 or 1154 later when trying to build 292077 or later before rebuilding. 1155 115620151207: 1157 Debug data files are now built by default with 'make buildworld' and 1158 installed with 'make installworld'. This facilitates debugging but 1159 requires more disk space both during the build and for the installed 1160 world. Debug files may be disabled by setting WITHOUT_DEBUG_FILES=yes 1161 in src.conf(5). 1162 116320151130: 1164 r291527 changed the internal interface between the nfsd.ko and 1165 nfscommon.ko modules. As such, they must both be upgraded to-gether. 1166 __FreeBSD_version has been bumped because of this. 1167 116820151108: 1169 Add support for unicode collation strings leads to a change of 1170 order of files listed by ls(1) for example. To get back to the old 1171 behaviour, set LC_COLLATE environment variable to "C". 1172 1173 Databases administrators will need to reindex their databases given 1174 collation results will be different. 1175 1176 Due to a bug in install(1) it is recommended to remove the ancient 1177 locales before running make installworld. 1178 1179 rm -rf /usr/share/locale/* 1180 118120151030: 1182 The OpenSSL has been upgraded to 1.0.2d. Any binaries requiring 1183 libcrypto.so.7 or libssl.so.7 must be recompiled. 1184 118520151020: 1186 Qlogic 24xx/25xx firmware images were updated from 5.5.0 to 7.3.0. 1187 Kernel modules isp_2400_multi and isp_2500_multi were removed and 1188 should be replaced with isp_2400 and isp_2500 modules respectively. 1189 119020151017: 1191 The build previously allowed using 'make -n' to not recurse into 1192 sub-directories while showing what commands would be executed, and 1193 'make -n -n' to recursively show commands. Now 'make -n' will recurse 1194 and 'make -N' will not. 1195 119620151012: 1197 If you specify SENDMAIL_MC or SENDMAIL_CF in make.conf, mergemaster 1198 and etcupdate will now use this file. A custom sendmail.cf is now 1199 updated via this mechanism rather than via installworld. If you had 1200 excluded sendmail.cf in mergemaster.rc or etcupdate.conf, you may 1201 want to remove the exclusion or change it to "always install". 1202 /etc/mail/sendmail.cf is now managed the same way regardless of 1203 whether SENDMAIL_MC/SENDMAIL_CF is used. If you are not using 1204 SENDMAIL_MC/SENDMAIL_CF there should be no change in behavior. 1205 120620151011: 1207 Compatibility shims for legacy ATA device names have been removed. 1208 It includes ATA_STATIC_ID kernel option, kern.cam.ada.legacy_aliases 1209 and kern.geom.raid.legacy_aliases loader tunables, kern.devalias.* 1210 environment variables, /dev/ad* and /dev/ar* symbolic links. 1211 121220151006: 1213 Clang, llvm, lldb, compiler-rt and libc++ have been upgraded to 3.7.0. 1214 Please see the 20141231 entry below for information about prerequisites 1215 and upgrading, if you are not already using clang 3.5.0 or higher. 1216 121720150924: 1218 Kernel debug files have been moved to /usr/lib/debug/boot/kernel/, 1219 and renamed from .symbols to .debug. This reduces the size requirements 1220 on the boot partition or file system and provides consistency with 1221 userland debug files. 1222 1223 When using the supported kernel installation method the 1224 /usr/lib/debug/boot/kernel directory will be renamed (to kernel.old) 1225 as is done with /boot/kernel. 1226 1227 Developers wishing to maintain the historical behavior of installing 1228 debug files in /boot/kernel/ can set KERN_DEBUGDIR="" in src.conf(5). 1229 123020150827: 1231 The wireless drivers had undergone changes that remove the 'parent 1232 interface' from the ifconfig -l output. The rc.d network scripts 1233 used to check presence of a parent interface in the list, so old 1234 scripts would fail to start wireless networking. Thus, etcupdate(3) 1235 or mergemaster(8) run is required after kernel update, to update your 1236 rc.d scripts in /etc. 1237 123820150827: 1239 pf no longer supports 'scrub fragment crop' or 'scrub fragment drop-ovl' 1240 These configurations are now automatically interpreted as 1241 'scrub fragment reassemble'. 1242 124320150817: 1244 Kernel-loadable modules for the random(4) device are back. To use 1245 them, the kernel must have 1246 1247 device random 1248 options RANDOM_LOADABLE 1249 1250 kldload(8) can then be used to load random_fortuna.ko 1251 or random_yarrow.ko. Please note that due to the indirect 1252 function calls that the loadable modules need to provide, 1253 the build-in variants will be slightly more efficient. 1254 1255 The random(4) kernel option RANDOM_DUMMY has been retired due to 1256 unpopularity. It was not all that useful anyway. 1257 125820150813: 1259 The WITHOUT_ELFTOOLCHAIN_TOOLS src.conf(5) knob has been retired. 1260 Control over building the ELF Tool Chain tools is now provided by 1261 the WITHOUT_TOOLCHAIN knob. 1262 126320150810: 1264 The polarity of Pulse Per Second (PPS) capture events with the 1265 uart(4) driver has been corrected. Prior to this change the PPS 1266 "assert" event corresponded to the trailing edge of a positive PPS 1267 pulse and the "clear" event was the leading edge of the next pulse. 1268 1269 As the width of a PPS pulse in a typical GPS receiver is on the 1270 order of 1 millisecond, most users will not notice any significant 1271 difference with this change. 1272 1273 Anyone who has compensated for the historical polarity reversal by 1274 configuring a negative offset equal to the pulse width will need to 1275 remove that workaround. 1276 127720150809: 1278 The default group assigned to /dev/dri entries has been changed 1279 from 'wheel' to 'video' with the id of '44'. If you want to have 1280 access to the dri devices please add yourself to the video group 1281 with: 1282 1283 # pw groupmod video -m $USER 1284 128520150806: 1286 The menu.rc and loader.rc files will now be replaced during 1287 upgrades. Please migrate local changes to menu.rc.local and 1288 loader.rc.local instead. 1289 129020150805: 1291 GNU Binutils versions of addr2line, c++filt, nm, readelf, size, 1292 strings and strip have been removed. The src.conf(5) knob 1293 WITHOUT_ELFTOOLCHAIN_TOOLS no longer provides the binutils tools. 1294 129520150728: 1296 As ZFS requires more kernel stack pages than is the default on some 1297 architectures e.g. i386, it now warns if KSTACK_PAGES is less than 1298 ZFS_MIN_KSTACK_PAGES (which is 4 at the time of writing). 1299 1300 Please consider using 'options KSTACK_PAGES=X' where X is greater 1301 than or equal to ZFS_MIN_KSTACK_PAGES i.e. 4 in such configurations. 1302 130320150706: 1304 sendmail has been updated to 8.15.2. Starting with FreeBSD 11.0 1305 and sendmail 8.15, sendmail uses uncompressed IPv6 addresses by 1306 default, i.e., they will not contain "::". For example, instead 1307 of ::1, it will be 0:0:0:0:0:0:0:1. This permits a zero subnet 1308 to have a more specific match, such as different map entries for 1309 IPv6:0:0 vs IPv6:0. This change requires that configuration 1310 data (including maps, files, classes, custom ruleset, etc.) must 1311 use the same format, so make certain such configuration data is 1312 upgrading. As a very simple check search for patterns like 1313 'IPv6:[0-9a-fA-F:]*::' and 'IPv6::'. To return to the old 1314 behavior, set the m4 option confUSE_COMPRESSED_IPV6_ADDRESSES or 1315 the cf option UseCompressedIPv6Addresses. 1316 131720150630: 1318 The default kernel entropy-processing algorithm is now 1319 Fortuna, replacing Yarrow. 1320 1321 Assuming you have 'device random' in your kernel config 1322 file, the configurations allow a kernel option to override 1323 this default. You may choose *ONE* of: 1324 1325 options RANDOM_YARROW # Legacy /dev/random algorithm. 1326 options RANDOM_DUMMY # Blocking-only driver. 1327 1328 If you have neither, you get Fortuna. For most people, 1329 read no further, Fortuna will give a /dev/random that works 1330 like it always used to, and the difference will be irrelevant. 1331 1332 If you remove 'device random', you get *NO* kernel-processed 1333 entropy at all. This may be acceptable to folks building 1334 embedded systems, but has complications. Carry on reading, 1335 and it is assumed you know what you need. 1336 1337 *PLEASE* read random(4) and random(9) if you are in the 1338 habit of tweaking kernel configs, and/or if you are a member 1339 of the embedded community, wanting specific and not-usual 1340 behaviour from your security subsystems. 1341 1342 NOTE!! If you use RANDOM_DUMMY and/or have no 'device 1343 random', you will NOT have a functioning /dev/random, and 1344 many cryptographic features will not work, including SSH. 1345 You may also find strange behaviour from the random(3) set 1346 of library functions, in particular sranddev(3), srandomdev(3) 1347 and arc4random(3). The reason for this is that the KERN_ARND 1348 sysctl only returns entropy if it thinks it has some to 1349 share, and with RANDOM_DUMMY or no 'device random' this 1350 will never happen. 1351 135220150623: 1353 An additional fix for the issue described in the 20150614 sendmail 1354 entry below has been committed in revision 284717. 1355 135620150616: 1357 FreeBSD's old make (fmake) has been removed from the system. It is 1358 available as the devel/fmake port or via pkg install fmake. 1359 136020150615: 1361 The fix for the issue described in the 20150614 sendmail entry 1362 below has been committed in revision 284436. The work 1363 around described in that entry is no longer needed unless the 1364 default setting is overridden by a confDH_PARAMETERS configuration 1365 setting of '5' or pointing to a 512 bit DH parameter file. 1366 136720150614: 1368 ALLOW_DEPRECATED_ATF_TOOLS/ATFFILE support has been removed from 1369 atf.test.mk (included from bsd.test.mk). Please upgrade devel/atf 1370 and devel/kyua to version 0.20+ and adjust any calling code to work 1371 with Kyuafile and kyua. 1372 137320150614: 1374 The import of openssl to address the FreeBSD-SA-15:10.openssl 1375 security advisory includes a change which rejects handshakes 1376 with DH parameters below 768 bits. sendmail releases prior 1377 to 8.15.2 (not yet released), defaulted to a 512 bit 1378 DH parameter setting for client connections. To work around 1379 this interoperability, sendmail can be configured to use a 1380 2048 bit DH parameter by: 1381 1382 1. Edit /etc/mail/`hostname`.mc 1383 2. If a setting for confDH_PARAMETERS does not exist or 1384 exists and is set to a string beginning with '5', 1385 replace it with '2'. 1386 3. If a setting for confDH_PARAMETERS exists and is set to 1387 a file path, create a new file with: 1388 openssl dhparam -out /path/to/file 2048 1389 4. Rebuild the .cf file: 1390 cd /etc/mail/; make; make install 1391 5. Restart sendmail: 1392 cd /etc/mail/; make restart 1393 1394 A sendmail patch is coming, at which time this file will be 1395 updated. 1396 139720150604: 1398 Generation of legacy formatted entries have been disabled by default 1399 in pwd_mkdb(8), as all base system consumers of the legacy formatted 1400 entries were converted to use the new format by default when the new, 1401 machine independent format have been added and supported since FreeBSD 1402 5.x. 1403 1404 Please see the pwd_mkdb(8) manual page for further details. 1405 140620150525: 1407 Clang and llvm have been upgraded to 3.6.1 release. Please see the 1408 20141231 entry below for information about prerequisites and upgrading, 1409 if you are not already using 3.5.0 or higher. 1410 141120150521: 1412 TI platform code switched to using vendor DTS files and this update 1413 may break existing systems running on Beaglebone, Beaglebone Black, 1414 and Pandaboard: 1415 1416 - dtb files should be regenerated/reinstalled. Filenames are the 1417 same but content is different now 1418 - GPIO addressing was changed, now each GPIO bank (32 pins per bank) 1419 has its own /dev/gpiocX device, e.g. pin 121 on /dev/gpioc0 in old 1420 addressing scheme is now pin 25 on /dev/gpioc3. 1421 - Pandaboard: /etc/ttys should be updated, serial console device is 1422 now /dev/ttyu2, not /dev/ttyu0 1423 142420150501: 1425 soelim(1) from gnu/usr.bin/groff has been replaced by usr.bin/soelim. 1426 If you need the GNU extension from groff soelim(1), install groff 1427 from package: pkg install groff, or via ports: textproc/groff. 1428 142920150423: 1430 chmod, chflags, chown and chgrp now affect symlinks in -R mode as 1431 defined in symlink(7); previously symlinks were silently ignored. 1432 143320150415: 1434 The const qualifier has been removed from iconv(3) to comply with 1435 POSIX. The ports tree is aware of this from r384038 onwards. 1436 143720150416: 1438 Libraries specified by LIBADD in Makefiles must have a corresponding 1439 DPADD_<lib> variable to ensure correct dependencies. This is now 1440 enforced in src.libnames.mk. 1441 144220150324: 1443 From legacy ata(4) driver was removed support for SATA controllers 1444 supported by more functional drivers ahci(4), siis(4) and mvs(4). 1445 Kernel modules ataahci and ataadaptec were removed completely, 1446 replaced by ahci and mvs modules respectively. 1447 144820150315: 1449 Clang, llvm and lldb have been upgraded to 3.6.0 release. Please see 1450 the 20141231 entry below for information about prerequisites and 1451 upgrading, if you are not already using 3.5.0 or higher. 1452 145320150307: 1454 The 32-bit PowerPC kernel has been changed to a position-independent 1455 executable. This can only be booted with a version of loader(8) 1456 newer than January 31, 2015, so make sure to update both world and 1457 kernel before rebooting. 1458 145920150217: 1460 If you are running a -CURRENT kernel since r273872 (Oct 30th, 2014), 1461 but before r278950, the RNG was not seeded properly. Immediately 1462 upgrade the kernel to r278950 or later and regenerate any keys (e.g. 1463 ssh keys or openssl keys) that were generated w/ a kernel from that 1464 range. This does not affect programs that directly used /dev/random 1465 or /dev/urandom. All userland uses of arc4random(3) are affected. 1466 146720150210: 1468 The autofs(4) ABI was changed in order to restore binary compatibility 1469 with 10.1-RELEASE. The automountd(8) daemon needs to be rebuilt to work 1470 with the new kernel. 1471 147220150131: 1473 The powerpc64 kernel has been changed to a position-independent 1474 executable. This can only be booted with a new version of loader(8), 1475 so make sure to update both world and kernel before rebooting. 1476 147720150118: 1478 Clang and llvm have been upgraded to 3.5.1 release. This is a bugfix 1479 only release, no new features have been added. Please see the 20141231 1480 entry below for information about prerequisites and upgrading, if you 1481 are not already using 3.5.0. 1482 148320150107: 1484 ELF tools addr2line, elfcopy (strip), nm, size, and strings are now 1485 taken from the ELF Tool Chain project rather than GNU binutils. They 1486 should be drop-in replacements, with the addition of arm64 support. 1487 The WITHOUT_ELFTOOLCHAIN_TOOLS= knob may be used to obtain the 1488 binutils tools, if necessary. See 20150805 for updated information. 1489 149020150105: 1491 The default Unbound configuration now enables remote control 1492 using a local socket. Users who have already enabled the 1493 local_unbound service should regenerate their configuration 1494 by running "service local_unbound setup" as root. 1495 149620150102: 1497 The GNU texinfo and GNU info pages have been removed. 1498 To be able to view GNU info pages please install texinfo from ports. 1499 150020141231: 1501 Clang, llvm and lldb have been upgraded to 3.5.0 release. 1502 1503 As of this release, a prerequisite for building clang, llvm and lldb is 1504 a C++11 capable compiler and C++11 standard library. This means that to 1505 be able to successfully build the cross-tools stage of buildworld, with 1506 clang as the bootstrap compiler, your system compiler or cross compiler 1507 should either be clang 3.3 or later, or gcc 4.8 or later, and your 1508 system C++ library should be libc++, or libdstdc++ from gcc 4.8 or 1509 later. 1510 1511 On any standard FreeBSD 10.x or 11.x installation, where clang and 1512 libc++ are on by default (that is, on x86 or arm), this should work out 1513 of the box. 1514 1515 On 9.x installations where clang is enabled by default, e.g. on x86 and 1516 powerpc, libc++ will not be enabled by default, so libc++ should be 1517 built (with clang) and installed first. If both clang and libc++ are 1518 missing, build clang first, then use it to build libc++. 1519 1520 On 8.x and earlier installations, upgrade to 9.x first, and then follow 1521 the instructions for 9.x above. 1522 1523 Sparc64 and mips users are unaffected, as they still use gcc 4.2.1 by 1524 default, and do not build clang. 1525 1526 Many embedded systems are resource constrained, and will not be able to 1527 build clang in a reasonable time, or in some cases at all. In those 1528 cases, cross building bootable systems on amd64 is a workaround. 1529 1530 This new version of clang introduces a number of new warnings, of which 1531 the following are most likely to appear: 1532 1533 -Wabsolute-value 1534 1535 This warns in two cases, for both C and C++: 1536 * When the code is trying to take the absolute value of an unsigned 1537 quantity, which is effectively a no-op, and almost never what was 1538 intended. The code should be fixed, if at all possible. If you are 1539 sure that the unsigned quantity can be safely cast to signed, without 1540 loss of information or undefined behavior, you can add an explicit 1541 cast, or disable the warning. 1542 1543 * When the code is trying to take an absolute value, but the called 1544 abs() variant is for the wrong type, which can lead to truncation. 1545 If you want to disable the warning instead of fixing the code, please 1546 make sure that truncation will not occur, or it might lead to unwanted 1547 side-effects. 1548 1549 -Wtautological-undefined-compare and 1550 -Wundefined-bool-conversion 1551 1552 These warn when C++ code is trying to compare 'this' against NULL, while 1553 'this' should never be NULL in well-defined C++ code. However, there is 1554 some legacy (pre C++11) code out there, which actively abuses this 1555 feature, which was less strictly defined in previous C++ versions. 1556 1557 Squid and openjdk do this, for example. The warning can be turned off 1558 for C++98 and earlier, but compiling the code in C++11 mode might result 1559 in unexpected behavior; for example, the parts of the program that are 1560 unreachable could be optimized away. 1561 156220141222: 1563 The old NFS client and server (kernel options NFSCLIENT, NFSSERVER) 1564 kernel sources have been removed. The .h files remain, since some 1565 utilities include them. This will need to be fixed later. 1566 If "mount -t oldnfs ..." is attempted, it will fail. 1567 If the "-o" option on mountd(8), nfsd(8) or nfsstat(1) is used, 1568 the utilities will report errors. 1569 157020141121: 1571 The handling of LOCAL_LIB_DIRS has been altered to skip addition of 1572 directories to top level SUBDIR variable when their parent 1573 directory is included in LOCAL_DIRS. Users with build systems with 1574 such hierarchies and without SUBDIR entries in the parent 1575 directory Makefiles should add them or add the directories to 1576 LOCAL_DIRS. 1577 157820141109: 1579 faith(4) and faithd(8) have been removed from the base system. Faith 1580 has been obsolete for a very long time. 1581 158220141104: 1583 vt(4), the new console driver, is enabled by default. It brings 1584 support for Unicode and double-width characters, as well as 1585 support for UEFI and integration with the KMS kernel video 1586 drivers. 1587 1588 You may need to update your console settings in /etc/rc.conf, 1589 most probably the keymap. During boot, /etc/rc.d/syscons will 1590 indicate what you need to do. 1591 1592 vt(4) still has issues and lacks some features compared to 1593 syscons(4). See the wiki for up-to-date information: 1594 https://wiki.freebsd.org/Newcons 1595 1596 If you want to keep using syscons(4), you can do so by adding 1597 the following line to /boot/loader.conf: 1598 kern.vty=sc 1599 160020141102: 1601 pjdfstest has been integrated into kyua as an opt-in test suite. 1602 Please see share/doc/pjdfstest/README for more details on how to 1603 execute it. 1604 160520141009: 1606 gperf has been removed from the base system for architectures 1607 that use clang. Ports that require gperf will obtain it from the 1608 devel/gperf port. 1609 161020140923: 1611 pjdfstest has been moved from tools/regression/pjdfstest to 1612 contrib/pjdfstest . 1613 161420140922: 1615 At svn r271982, The default linux compat kernel ABI has been adjusted 1616 to 2.6.18 in support of the linux-c6 compat ports infrastructure 1617 update. If you wish to continue using the linux-f10 compat ports, 1618 add compat.linux.osrelease=2.6.16 to your local sysctl.conf. Users are 1619 encouraged to update their linux-compat packages to linux-c6 during 1620 their next update cycle. 1621 162220140729: 1623 The ofwfb driver, used to provide a graphics console on PowerPC when 1624 using vt(4), no longer allows mmap() of all physical memory. This 1625 will prevent Xorg on PowerPC with some ATI graphics cards from 1626 initializing properly unless x11-servers/xorg-server is updated to 1627 1.12.4_8 or newer. 1628 162920140723: 1630 The xdev targets have been converted to using TARGET and 1631 TARGET_ARCH instead of XDEV and XDEV_ARCH. 1632 163320140719: 1634 The default unbound configuration has been modified to address 1635 issues with reverse lookups on networks that use private 1636 address ranges. If you use the local_unbound service, run 1637 "service local_unbound setup" as root to regenerate your 1638 configuration, then "service local_unbound reload" to load the 1639 new configuration. 1640 164120140709: 1642 The GNU texinfo and GNU info pages are not built and installed 1643 anymore, WITH_INFO knob has been added to allow to built and install 1644 them again. 1645 UPDATE: see 20150102 entry on texinfo's removal 1646 164720140708: 1648 The GNU readline library is now an INTERNALLIB - that is, it is 1649 statically linked into consumers (GDB and variants) in the base 1650 system, and the shared library is no longer installed. The 1651 devel/readline port is available for third party software that 1652 requires readline. 1653 165420140702: 1655 The Itanium architecture (ia64) has been removed from the list of 1656 known architectures. This is the first step in the removal of the 1657 architecture. 1658 165920140701: 1660 Commit r268115 has added NFSv4.1 server support, merged from 1661 projects/nfsv4.1-server. Since this includes changes to the 1662 internal interfaces between the NFS related modules, a full 1663 build of the kernel and modules will be necessary. 1664 __FreeBSD_version has been bumped. 1665 166620140629: 1667 The WITHOUT_VT_SUPPORT kernel config knob has been renamed 1668 WITHOUT_VT. (The other _SUPPORT knobs have a consistent meaning 1669 which differs from the behaviour controlled by this knob.) 1670 167120140619: 1672 Maximal length of the serial number in CTL was increased from 16 to 1673 64 chars, that breaks ABI. All CTL-related tools, such as ctladm 1674 and ctld, need to be rebuilt to work with a new kernel. 1675 167620140606: 1677 The libatf-c and libatf-c++ major versions were downgraded to 0 and 1678 1 respectively to match the upstream numbers. They were out of 1679 sync because, when they were originally added to FreeBSD, the 1680 upstream versions were not respected. These libraries are private 1681 and not yet built by default, so renumbering them should be a 1682 non-issue. However, unclean source trees will yield broken test 1683 programs once the operator executes "make delete-old-libs" after a 1684 "make installworld". 1685 1686 Additionally, the atf-sh binary was made private by moving it into 1687 /usr/libexec/. Already-built shell test programs will keep the 1688 path to the old binary so they will break after "make delete-old" 1689 is run. 1690 1691 If you are using WITH_TESTS=yes (not the default), wipe the object 1692 tree and rebuild from scratch to prevent spurious test failures. 1693 This is only needed once: the misnumbered libraries and misplaced 1694 binaries have been added to OptionalObsoleteFiles.inc so they will 1695 be removed during a clean upgrade. 1696 169720140512: 1698 Clang and llvm have been upgraded to 3.4.1 release. 1699 170020140508: 1701 We bogusly installed src.opts.mk in /usr/share/mk. This file should 1702 be removed to avoid issues in the future (and has been added to 1703 ObsoleteFiles.inc). 1704 170520140505: 1706 /etc/src.conf now affects only builds of the FreeBSD src tree. In the 1707 past, it affected all builds that used the bsd.*.mk files. The old 1708 behavior was a bug, but people may have relied upon it. To get this 1709 behavior back, you can .include /etc/src.conf from /etc/make.conf 1710 (which is still global and isn't changed). This also changes the 1711 behavior of incremental builds inside the tree of individual 1712 directories. Set MAKESYSPATH to ".../share/mk" to do that. 1713 Although this has survived make universe and some upgrade scenarios, 1714 other upgrade scenarios may have broken. At least one form of 1715 temporary breakage was fixed with MAKESYSPATH settings for buildworld 1716 as well... In cases where MAKESYSPATH isn't working with this 1717 setting, you'll need to set it to the full path to your tree. 1718 1719 One side effect of all this cleaning up is that bsd.compiler.mk 1720 is no longer implicitly included by bsd.own.mk. If you wish to 1721 use COMPILER_TYPE, you must now explicitly include bsd.compiler.mk 1722 as well. 1723 172420140430: 1725 The lindev device has been removed since /dev/full has been made a 1726 standard device. __FreeBSD_version has been bumped. 1727 172820140424: 1729 The knob WITHOUT_VI was added to the base system, which controls 1730 building ex(1), vi(1), etc. Older releases of FreeBSD required ex(1) 1731 in order to reorder files share/termcap and didn't build ex(1) as a 1732 build tool, so building/installing with WITH_VI is highly advised for 1733 build hosts for older releases. 1734 1735 This issue has been fixed in stable/9 and stable/10 in r277022 and 1736 r276991, respectively. 1737 173820140418: 1739 The YES_HESIOD knob has been removed. It has been obsolete for 1740 a decade. Please move to using WITH_HESIOD instead or your builds 1741 will silently lack HESIOD. 1742 174320140405: 1744 The uart(4) driver has been changed with respect to its handling 1745 of the low-level console. Previously the uart(4) driver prevented 1746 any process from changing the baudrate or the CLOCAL and HUPCL 1747 control flags. By removing the restrictions, operators can make 1748 changes to the serial console port without having to reboot. 1749 However, when getty(8) is started on the serial device that is 1750 associated with the low-level console, a misconfigured terminal 1751 line in /etc/ttys will now have a real impact. 1752 Before upgrading the kernel, make sure that /etc/ttys has the 1753 serial console device configured as 3wire without baudrate to 1754 preserve the previous behaviour. E.g: 1755 ttyu0 "/usr/libexec/getty 3wire" vt100 on secure 1756 175720140306: 1758 Support for libwrap (TCP wrappers) in rpcbind was disabled by default 1759 to improve performance. To re-enable it, if needed, run rpcbind 1760 with command line option -W. 1761 176220140226: 1763 Switched back to the GPL dtc compiler due to updates in the upstream 1764 dts files not being supported by the BSDL dtc compiler. You will need 1765 to rebuild your kernel toolchain to pick up the new compiler. Core dumps 1766 may result while building dtb files during a kernel build if you fail 1767 to do so. Set WITHOUT_GPL_DTC if you require the BSDL compiler. 1768 176920140216: 1770 Clang and llvm have been upgraded to 3.4 release. 1771 177220140216: 1773 The nve(4) driver has been removed. Please use the nfe(4) driver 1774 for NVIDIA nForce MCP Ethernet adapters instead. 1775 177620140212: 1777 An ABI incompatibility crept into the libc++ 3.4 import in r261283. 1778 This could cause certain C++ applications using shared libraries built 1779 against the previous version of libc++ to crash. The incompatibility 1780 has now been fixed, but any C++ applications or shared libraries built 1781 between r261283 and r261801 should be recompiled. 1782 178320140204: 1784 OpenSSH will now ignore errors caused by kernel lacking of Capsicum 1785 capability mode support. Please note that enabling the feature in 1786 kernel is still highly recommended. 1787 178820140131: 1789 OpenSSH is now built with sandbox support, and will use sandbox as 1790 the default privilege separation method. This requires Capsicum 1791 capability mode support in kernel. 1792 179320140128: 1794 The libelf and libdwarf libraries have been updated to newer 1795 versions from upstream. Shared library version numbers for 1796 these two libraries were bumped. Any ports or binaries 1797 requiring these two libraries should be recompiled. 1798 __FreeBSD_version is bumped to 1100006. 1799 180020140110: 1801 If a Makefile in a tests/ directory was auto-generating a Kyuafile 1802 instead of providing an explicit one, this would prevent such 1803 Makefile from providing its own Kyuafile in the future during 1804 NO_CLEAN builds. This has been fixed in the Makefiles but manual 1805 intervention is needed to clean an objdir if you use NO_CLEAN: 1806 # find /usr/obj -name Kyuafile | xargs rm -f 1807 180820131213: 1809 The behavior of gss_pseudo_random() for the krb5 mechanism 1810 has changed, for applications requesting a longer random string 1811 than produced by the underlying enctype's pseudo-random() function. 1812 In particular, the random string produced from a session key of 1813 enctype aes256-cts-hmac-sha1-96 or aes256-cts-hmac-sha1-96 will 1814 be different at the 17th octet and later, after this change. 1815 The counter used in the PRF+ construction is now encoded as a 1816 big-endian integer in accordance with RFC 4402. 1817 __FreeBSD_version is bumped to 1100004. 1818 181920131108: 1820 The WITHOUT_ATF build knob has been removed and its functionality 1821 has been subsumed into the more generic WITHOUT_TESTS. If you were 1822 using the former to disable the build of the ATF libraries, you 1823 should change your settings to use the latter. 1824 182520131025: 1826 The default version of mtree is nmtree which is obtained from 1827 NetBSD. The output is generally the same, but may vary 1828 slightly. If you found you need identical output adding 1829 "-F freebsd9" to the command line should do the trick. For the 1830 time being, the old mtree is available as fmtree. 1831 183220131014: 1833 libbsdyml has been renamed to libyaml and moved to /usr/lib/private. 1834 This will break ports-mgmt/pkg. Rebuild the port, or upgrade to pkg 1835 1.1.4_8 and verify bsdyml not linked in, before running "make 1836 delete-old-libs": 1837 # make -C /usr/ports/ports-mgmt/pkg build deinstall install clean 1838 or 1839 # pkg install pkg; ldd /usr/local/sbin/pkg | grep bsdyml 1840 184120131010: 1842 The stable/10 branch has been created in subversion from head 1843 revision r256279. 1844 1845COMMON ITEMS: 1846 1847 General Notes 1848 ------------- 1849 Avoid using make -j when upgrading. While generally safe, there are 1850 sometimes problems using -j to upgrade. If your upgrade fails with 1851 -j, please try again without -j. From time to time in the past there 1852 have been problems using -j with buildworld and/or installworld. This 1853 is especially true when upgrading between "distant" versions (eg one 1854 that cross a major release boundary or several minor releases, or when 1855 several months have passed on the -current branch). 1856 1857 Sometimes, obscure build problems are the result of environment 1858 poisoning. This can happen because the make utility reads its 1859 environment when searching for values for global variables. To run 1860 your build attempts in an "environmental clean room", prefix all make 1861 commands with 'env -i '. See the env(1) manual page for more details. 1862 1863 When upgrading from one major version to another it is generally best to 1864 upgrade to the latest code in the currently installed branch first, then 1865 do an upgrade to the new branch. This is the best-tested upgrade path, 1866 and has the highest probability of being successful. Please try this 1867 approach if you encounter problems with a major version upgrade. Since 1868 the stable 4.x branch point, one has generally been able to upgrade from 1869 anywhere in the most recent stable branch to head / current (or even the 1870 last couple of stable branches). See the top of this file when there's 1871 an exception. 1872 1873 When upgrading a live system, having a root shell around before 1874 installing anything can help undo problems. Not having a root shell 1875 around can lead to problems if pam has changed too much from your 1876 starting point to allow continued authentication after the upgrade. 1877 1878 This file should be read as a log of events. When a later event changes 1879 information of a prior event, the prior event should not be deleted. 1880 Instead, a pointer to the entry with the new information should be 1881 placed in the old entry. Readers of this file should also sanity check 1882 older entries before relying on them blindly. Authors of new entries 1883 should write them with this in mind. 1884 1885 ZFS notes 1886 --------- 1887 When upgrading the boot ZFS pool to a new version, always follow 1888 these two steps: 1889 1890 1.) recompile and reinstall the ZFS boot loader and boot block 1891 (this is part of "make buildworld" and "make installworld") 1892 1893 2.) update the ZFS boot block on your boot drive 1894 1895 The following example updates the ZFS boot block on the first 1896 partition (freebsd-boot) of a GPT partitioned drive ada0: 1897 "gpart bootcode -p /boot/gptzfsboot -i 1 ada0" 1898 1899 Non-boot pools do not need these updates. 1900 1901 To build a kernel 1902 ----------------- 1903 If you are updating from a prior version of FreeBSD (even one just 1904 a few days old), you should follow this procedure. It is the most 1905 failsafe as it uses a /usr/obj tree with a fresh mini-buildworld, 1906 1907 make kernel-toolchain 1908 make -DALWAYS_CHECK_MAKE buildkernel KERNCONF=YOUR_KERNEL_HERE 1909 make -DALWAYS_CHECK_MAKE installkernel KERNCONF=YOUR_KERNEL_HERE 1910 1911 To test a kernel once 1912 --------------------- 1913 If you just want to boot a kernel once (because you are not sure 1914 if it works, or if you want to boot a known bad kernel to provide 1915 debugging information) run 1916 make installkernel KERNCONF=YOUR_KERNEL_HERE KODIR=/boot/testkernel 1917 nextboot -k testkernel 1918 1919 To rebuild everything and install it on the current system. 1920 ----------------------------------------------------------- 1921 # Note: sometimes if you are running current you gotta do more than 1922 # is listed here if you are upgrading from a really old current. 1923 1924 <make sure you have good level 0 dumps> 1925 make buildworld 1926 make buildkernel KERNCONF=YOUR_KERNEL_HERE 1927 make installkernel KERNCONF=YOUR_KERNEL_HERE 1928 [1] 1929 <reboot in single user> [3] 1930 mergemaster -Fp [5] 1931 make installworld 1932 mergemaster -Fi [4] 1933 make delete-old [6] 1934 <reboot> 1935 1936 To cross-install current onto a separate partition 1937 -------------------------------------------------- 1938 # In this approach we use a separate partition to hold 1939 # current's root, 'usr', and 'var' directories. A partition 1940 # holding "/", "/usr" and "/var" should be about 2GB in 1941 # size. 1942 1943 <make sure you have good level 0 dumps> 1944 <boot into -stable> 1945 make buildworld 1946 make buildkernel KERNCONF=YOUR_KERNEL_HERE 1947 <maybe newfs current's root partition> 1948 <mount current's root partition on directory ${CURRENT_ROOT}> 1949 make installworld DESTDIR=${CURRENT_ROOT} -DDB_FROM_SRC 1950 make distribution DESTDIR=${CURRENT_ROOT} # if newfs'd 1951 make installkernel KERNCONF=YOUR_KERNEL_HERE DESTDIR=${CURRENT_ROOT} 1952 cp /etc/fstab ${CURRENT_ROOT}/etc/fstab # if newfs'd 1953 <edit ${CURRENT_ROOT}/etc/fstab to mount "/" from the correct partition> 1954 <reboot into current> 1955 <do a "native" rebuild/install as described in the previous section> 1956 <maybe install compatibility libraries from ports/misc/compat*> 1957 <reboot> 1958 1959 1960 To upgrade in-place from stable to current 1961 ---------------------------------------------- 1962 <make sure you have good level 0 dumps> 1963 make buildworld [9] 1964 make buildkernel KERNCONF=YOUR_KERNEL_HERE [8] 1965 make installkernel KERNCONF=YOUR_KERNEL_HERE 1966 [1] 1967 <reboot in single user> [3] 1968 mergemaster -Fp [5] 1969 make installworld 1970 mergemaster -Fi [4] 1971 make delete-old [6] 1972 <reboot> 1973 1974 Make sure that you've read the UPDATING file to understand the 1975 tweaks to various things you need. At this point in the life 1976 cycle of current, things change often and you are on your own 1977 to cope. The defaults can also change, so please read ALL of 1978 the UPDATING entries. 1979 1980 Also, if you are tracking -current, you must be subscribed to 1981 freebsd-current@freebsd.org. Make sure that before you update 1982 your sources that you have read and understood all the recent 1983 messages there. If in doubt, please track -stable which has 1984 much fewer pitfalls. 1985 1986 [1] If you have third party modules, such as vmware, you 1987 should disable them at this point so they don't crash your 1988 system on reboot. 1989 1990 [3] From the bootblocks, boot -s, and then do 1991 fsck -p 1992 mount -u / 1993 mount -a 1994 cd src 1995 adjkerntz -i # if CMOS is wall time 1996 Also, when doing a major release upgrade, it is required that 1997 you boot into single user mode to do the installworld. 1998 1999 [4] Note: This step is non-optional. Failure to do this step 2000 can result in a significant reduction in the functionality of the 2001 system. Attempting to do it by hand is not recommended and those 2002 that pursue this avenue should read this file carefully, as well 2003 as the archives of freebsd-current and freebsd-hackers mailing lists 2004 for potential gotchas. The -U option is also useful to consider. 2005 See mergemaster(8) for more information. 2006 2007 [5] Usually this step is a no-op. However, from time to time 2008 you may need to do this if you get unknown user in the following 2009 step. It never hurts to do it all the time. You may need to 2010 install a new mergemaster (cd src/usr.sbin/mergemaster && make 2011 install) after the buildworld before this step if you last updated 2012 from current before 20130425 or from -stable before 20130430. 2013 2014 [6] This only deletes old files and directories. Old libraries 2015 can be deleted by "make delete-old-libs", but you have to make 2016 sure that no program is using those libraries anymore. 2017 2018 [8] The new kernel must be able to run existing binaries used by 2019 an installworld. When upgrading across major versions, the new 2020 kernel's configuration must include the correct COMPAT_FREEBSD<n> 2021 option for existing binaries (e.g. COMPAT_FREEBSD11 to run 11.x 2022 binaries). Failure to do so may leave you with a system that is 2023 hard to boot to recover. A GENERIC kernel will include suitable 2024 compatibility options to run binaries from older branches. 2025 2026 Make sure that you merge any new devices from GENERIC since the 2027 last time you updated your kernel config file. 2028 2029 [9] If CPUTYPE is defined in your /etc/make.conf, make sure to use the 2030 "?=" instead of the "=" assignment operator, so that buildworld can 2031 override the CPUTYPE if it needs to. 2032 2033 MAKEOBJDIRPREFIX must be defined in an environment variable, and 2034 not on the command line, or in /etc/make.conf. buildworld will 2035 warn if it is improperly defined. 2036FORMAT: 2037 2038This file contains a list, in reverse chronological order, of major 2039breakages in tracking -current. It is not guaranteed to be a complete 2040list of such breakages, and only contains entries since September 23, 2011. 2041If you need to see UPDATING entries from before that date, you will need 2042to fetch an UPDATING file from an older FreeBSD release. 2043 2044Copyright information: 2045 2046Copyright 1998-2009 M.
