These features attempt to detect 1469f7bcf3SWarner Losh incorrect use of system primitives, and encourage loud failure 1569f7bcf3SWarner Losh through extra sanity checking and fail stop semantics. They 1669f7bcf3SWarner Losh also substantially impact system performance. If you want to 1769f7bcf3SWarner Losh do performance measurement, benchmarking, and optimization, 1869f7bcf3SWarner Losh you'll want to turn them off. This includes various WITNESS- 1969f7bcf3SWarner Losh related kernel options, INVARIANTS, malloc debugging flags 2069f7bcf3SWarner Losh in userland, and various verbose features in the kernel. Many 2169f7bcf3SWarner Losh developers choose to disable these features on build machines 226bea5c3cSTom Rhodes to maximize performance. (To disable malloc debugging, run 236bea5c3cSTom Rhodes ln -s aj /etc/malloc.conf.) 24efc06131SSam Leffler 25c2c2a7c1SBjoern A.

Drivers dependent on net80211 now support 8423790ac0SSam Leffler DLT_IEEE802_11_RADIO instead of DLT_IEEE802_11. No 8523790ac0SSam Leffler user-visible data structures were changed but applications 8623790ac0SSam Leffler that use DLT_IEEE802_11 may require changes. 8723790ac0SSam Leffler Bump __FreeBSD_version to 800088. 8823790ac0SSam Leffler 89f6dfe47aSMarko Zec20090430: 90f6dfe47aSMarko Zec The layout of the following structs has changed: sysctl_oid, 91f6dfe47aSMarko Zec socket, ifnet, inpcbinfo, tcpcb, syncache_head, vnet_inet, 92f6dfe47aSMarko Zec vnet_inet6 and vnet_ipfw. Most modules need to be rebuild or 93f6dfe47aSMarko Zec panics may be experienced. World rebuild is required for 94f6dfe47aSMarko Zec correctly checking networking state from userland. 95f6dfe47aSMarko Zec Bump __FreeBSD_version to 800085. 96f6dfe47aSMarko Zec 9733cde130SBruce M Simpson20090429: 9833cde130SBruce M Simpson MLDv2 and Source-Specific Multicast (SSM) have been merged 9933cde130SBruce M Simpson to the IPv6 stack. VIMAGE hooks are in but not yet used. 10033cde130SBruce M Simpson The implementation of SSM within FreeBSD's IPv6 stack closely 10133cde130SBruce M Simpson follows the IPv4 implementation. 10233cde130SBruce M Simpson 10333cde130SBruce M Simpson For kernel developers: 10433cde130SBruce M Simpson 10533cde130SBruce M Simpson * The most important changes are that the ip6_output() and 10633cde130SBruce M Simpson ip6_input() paths no longer take the IN6_MULTI_LOCK, 10733cde130SBruce M Simpson and this lock has been downgraded to a non-recursive mutex. 10833cde130SBruce M Simpson 10933cde130SBruce M Simpson * As with the changes to the IPv4 stack to support SSM, filtering 11033cde130SBruce M Simpson of inbound multicast traffic must now be performed by transport 11133cde130SBruce M Simpson protocols within the IPv6 stack. This does not apply to TCP and 11233cde130SBruce M Simpson SCTP, however, it does apply to UDP in IPv6 and raw IPv6. 11333cde130SBruce M Simpson 11433cde130SBruce M Simpson * The KPIs used by IPv6 multicast are similar to those used by 11533cde130SBruce M Simpson the IPv4 stack, with the following differences: 11633cde130SBruce M Simpson * im6o_mc_filter() is analogous to imo_multicast_filter(). 11733cde130SBruce M Simpson * The legacy KAME entry points in6_joingroup and in6_leavegroup() 11833cde130SBruce M Simpson are shimmed to in6_mc_join() and in6_mc_leave() respectively. 11933cde130SBruce M Simpson * IN6_LOOKUP_MULTI() has been deprecated and removed. 12033cde130SBruce M Simpson * IPv6 relies on MLD for the DAD mechanism. KAME's internal KPIs 12133cde130SBruce M Simpson for MLDv1 have an additional 'timer' argument which is used to 12233cde130SBruce M Simpson jitter the initial membership report for the solicited-node 12333cde130SBruce M Simpson multicast membership on-link. 12433cde130SBruce M Simpson * This is not strictly needed for MLDv2, which already jitters 12533cde130SBruce M Simpson its report transmissions. However, the 'timer' argument is 12633cde130SBruce M Simpson preserved in case MLDv1 is active on the interface. 12733cde130SBruce M Simpson 12833cde130SBruce M Simpson * The KAME linked-list based IPv6 membership implementation has 12933cde130SBruce M Simpson been refactored to use a vector similar to that used by the IPv4 13033cde130SBruce M Simpson stack. 13133cde130SBruce M Simpson Code which maintains a list of its own multicast memberships 13233cde130SBruce M Simpson internally, e.g. carp, has been updated to reflect the new 13333cde130SBruce M Simpson semantics. 13433cde130SBruce M Simpson 13533cde130SBruce M Simpson * There is a known Lock Order Reversal (LOR) due to in6_setscope() 13633cde130SBruce M Simpson acquiring the IF_AFDATA_LOCK and being called within ip6_output(). 13733cde130SBruce M Simpson Whilst MLDv2 tries to avoid this otherwise benign LOR, it is an 13833cde130SBruce M Simpson implementation constraint which needs to be addressed in HEAD. 13933cde130SBruce M Simpson 14033cde130SBruce M Simpson For application developers: 14133cde130SBruce M Simpson 14233cde130SBruce M Simpson * The changes are broadly similar to those made for the IPv4 14333cde130SBruce M Simpson stack. 14433cde130SBruce M Simpson 14533cde130SBruce M Simpson * The use of IPv4 and IPv6 multicast socket options on the same 14633cde130SBruce M Simpson socket, using mapped addresses, HAS NOT been tested or supported. 14733cde130SBruce M Simpson 14833cde130SBruce M Simpson * There are a number of issues with the implementation of various 14933cde130SBruce M Simpson IPv6 multicast APIs which need to be resolved in the API surface 15033cde130SBruce M Simpson before the implementation is fully compatible with KAME userland 15133cde130SBruce M Simpson use, and these are mostly to do with interface index treatment. 15233cde130SBruce M Simpson 15333cde130SBruce M Simpson * The literature available discusses the use of either the delta / ASM 15433cde130SBruce M Simpson API with setsockopt(2)/getsockopt(2), or the full-state / ASM API 15533cde130SBruce M Simpson using setsourcefilter(3)/getsourcefilter(3). For more information 15633cde130SBruce M Simpson please refer to RFC 3768, 'Socket Interface Extensions for 15733cde130SBruce M Simpson Multicast Source Filters'. 15833cde130SBruce M Simpson 15933cde130SBruce M Simpson * Applications which use the published RFC 3678 APIs should be fine. 16033cde130SBruce M Simpson 16133cde130SBruce M Simpson For systems administrators: 16233cde130SBruce M Simpson 16333cde130SBruce M Simpson * The mtest(8) utility has been refactored to support IPv6, in 16433cde130SBruce M Simpson addition to IPv4. Interface addresses are no longer accepted 16533cde130SBruce M Simpson as arguments, their names must be used instead. The utility 16633cde130SBruce M Simpson will map the interface name to its first IPv4 address as 16733cde130SBruce M Simpson returned by getifaddrs(3). 16833cde130SBruce M Simpson 16933cde130SBruce M Simpson * The ifmcstat(8) utility has also been updated to print the MLDv2 17033cde130SBruce M Simpson endpoint state and source filter lists via sysctl(3). 17133cde130SBruce M Simpson 17233cde130SBruce M Simpson * The net.inet6.ip6.mcast.loop sysctl may be tuned to 0 to disable 17333cde130SBruce M Simpson loopback of IPv6 multicast datagrams by default; it defaults to 1 17433cde130SBruce M Simpson to preserve the existing behaviour. Disabling multicast loopback is 17533cde130SBruce M Simpson recommended for optimal system performance. 17633cde130SBruce M Simpson 17733cde130SBruce M Simpson * The IPv6 MROUTING code has been changed to examine this sysctl 17833cde130SBruce M Simpson instead of attempting to perform a group lookup before looping 17933cde130SBruce M Simpson back forwarded datagrams. 18033cde130SBruce M Simpson 18133cde130SBruce M Simpson Bump __FreeBSD_version to 800084. 18233cde130SBruce M Simpson 1838b8bf775SRobert Watson20090422: 184131cdffbSMaksim Yevmenkin Implement low-level Bluetooth HCI API. 185131cdffbSMaksim Yevmenkin Bump __FreeBSD_version to 800083. 186131cdffbSMaksim Yevmenkin 1878b8bf775SRobert Watson20090419: 1888b8bf775SRobert Watson The layout of struct malloc_type, used by modules to register new 1898b8bf775SRobert Watson memory allocation types, has changed. Most modules will need to 1908b8bf775SRobert Watson be rebuilt or panics may be experienced. 1918b8bf775SRobert Watson Bump __FreeBSD_version to 800081. 1928b8bf775SRobert Watson 193de4ab55eSKip Macy20090415: 194773b573aSKip Macy Anticipate overflowing inp_flags - add inp_flags2. 195773b573aSKip Macy This changes most offsets in inpcb, so checking v4 connection 196773b573aSKip Macy state will require a world rebuild. 197773b573aSKip Macy Bump __FreeBSD_version to 800080. 198f146c211SXin LI 199773b573aSKip Macy20090415: 200de4ab55eSKip Macy Add an llentry to struct route and struct route_in6.

This is wrong and 21487437955SMaksim Yevmenkin apparently causing more problems than it solves. This will 21587437955SMaksim Yevmenkin re-open the issue where interrupt handlers may race with 21687437955SMaksim Yevmenkin kbdmux(4) in polling mode. Typical symptoms include (but 21787437955SMaksim Yevmenkin not limited to) duplicated and/or missing characters when 21887437955SMaksim Yevmenkin low level console functions (such as gets) are used while 21987437955SMaksim Yevmenkin interrupts are enabled (for example geli password prompt, 22087437955SMaksim Yevmenkin mountroot prompt etc.). Disabling kbdmux(4) may help. 22187437955SMaksim Yevmenkin 2222f6a1858SMarko Zec20090407: 2232f6a1858SMarko Zec The size of structs vnet_net, vnet_inet and vnet_ipfw has changed; 2242f6a1858SMarko Zec kernel modules referencing any of the above need to be recompiled. 2252f6a1858SMarko Zec Bump __FreeBSD_version to 800075. 2262f6a1858SMarko Zec 227781d043cSIvan Voras20090320: 228781d043cSIvan Voras GEOM_PART has become the default partition slicer for storage devices, 229781d043cSIvan Voras replacing GEOM_MBR, GEOM_BSD, GEOM_PC98 and GEOM_GPT slicers. It 2309a07b548SIvan Voras introduces some changes: 2319a07b548SIvan Voras 2329a07b548SIvan Voras MSDOS/EBR: the devices created from MSDOS extended partition entries 2339a07b548SIvan Voras (EBR) can be named differently than with GEOM_MBR and are now symlinks 2349a07b548SIvan Voras to devices with offset-based names. fstabs may need to be modified. 2359a07b548SIvan Voras 2369a07b548SIvan Voras BSD: the "geometry does not match label" warning is harmless in most 2379a07b548SIvan Voras cases but it points to problems in file system misalignment with 2389a07b548SIvan Voras disk geometry. The "c" partition is now implicit, covers the whole 2399a07b548SIvan Voras top-level drive and cannot be (mis)used by users. 2409a07b548SIvan Voras 2419a07b548SIvan Voras General: Kernel dumps are now not allowed to be written to devices 2429a07b548SIvan Voras whose partition types indicate they are meant to be used for file 2439a07b548SIvan Voras systems (or, in case of MSDOS partitions, as something else than 2449a07b548SIvan Voras the "386BSD" type). 2459a07b548SIvan Voras 2469a07b548SIvan Voras Most of these changes date approximately from 200812. 247781d043cSIvan Voras 248443fc317SBruce M Simpson20090319: 2492b78d306SAndrew Thompson The uscanner(4) driver has been removed from the kernel. This follows 2502b78d306SAndrew Thompson Linux removing theirs in 2.6 and making libusb the default interface 2512b78d306SAndrew Thompson (supported by sane). 2522b78d306SAndrew Thompson 2532b78d306SAndrew Thompson20090319: 254443fc317SBruce M Simpson The multicast forwarding code has been cleaned up. netstat(1) 255443fc317SBruce M Simpson only relies on KVM now for printing bandwidth upcall meters. 256443fc317SBruce M Simpson The IPv4 and IPv6 modules are split into ip_mroute_mod and 257443fc317SBruce M Simpson ip6_mroute_mod respectively. The config(5) options for statically 258443fc317SBruce M Simpson compiling this code remain the same, i.e. 'options MROUTING'. 259443fc317SBruce M Simpson 2601df14375SRobert Watson20090315: 2611df14375SRobert Watson Support for the IFF_NEEDSGIANT network interface flag has been 2621df14375SRobert Watson removed, which means that non-MPSAFE network device drivers are no 2631df14375SRobert Watson longer supported. In particular, if_ar, if_sr, and network device 2641df14375SRobert Watson drivers from the old (legacy) USB stack can no longer be built or 2651df14375SRobert Watson used. 2661df14375SRobert Watson 267e667034dSRui Paulo20090313: 2687e06afcaSGabor Kovesdan POSIX.1 Native Language Support (NLS) has been enabled in libc and 2697e06afcaSGabor Kovesdan a bunch of new language catalog files have also been added. 2707e06afcaSGabor Kovesdan This means that some common libc messages are now localized and 2717e06afcaSGabor Kovesdan they depend on the LC_MESSAGES environmental variable. 2727e06afcaSGabor Kovesdan 2737e06afcaSGabor Kovesdan20090313: 274e667034dSRui Paulo The k8temp(4) driver has been renamed to amdtemp(4) since 275e667034dSRui Paulo support for K10 and K11 CPU families was added. 276e667034dSRui Paulo 277a091d2a5SAndrew Thompson20090309: 278d10910e6SBruce M Simpson IGMPv3 and Source-Specific Multicast (SSM) have been merged 279d10910e6SBruce M Simpson to the IPv4 stack. VIMAGE hooks are in but not yet used. 280d10910e6SBruce M Simpson 281d10910e6SBruce M Simpson For kernel developers, the most important changes are that the 282d10910e6SBruce M Simpson ip_output() and ip_input() paths no longer take the IN_MULTI_LOCK(), 283d10910e6SBruce M Simpson and this lock has been downgraded to a non-recursive mutex. 284d10910e6SBruce M Simpson 285d10910e6SBruce M Simpson Transport protocols (UDP, Raw IP) are now responsible for filtering 286d10910e6SBruce M Simpson inbound multicast traffic according to group membership and source 287d10910e6SBruce M Simpson filters. The imo_multicast_filter() KPI exists for this purpose. 288d10910e6SBruce M Simpson Transports which do not use multicast (SCTP, TCP) already reject 289d10910e6SBruce M Simpson multicast by default. Forwarding and receive performance may improve 290d10910e6SBruce M Simpson as a mutex acquisition is no longer needed in the ip_input() 291d10910e6SBruce M Simpson low-level input path. in_addmulti() and in_delmulti() are shimmed 292d10910e6SBruce M Simpson to new KPIs which exist to support SSM in-kernel. 293d10910e6SBruce M Simpson 294d10910e6SBruce M Simpson For application developers, it is recommended that loopback of 295d10910e6SBruce M Simpson multicast datagrams be disabled for best performance, as this 296d10910e6SBruce M Simpson will still cause the lock to be taken for each looped-back 297d10910e6SBruce M Simpson datagram transmission. The net.inet.ip.mcast.loop sysctl may 298d10910e6SBruce M Simpson be tuned to 0 to disable loopback by default; it defaults to 1 299d10910e6SBruce M Simpson to preserve the existing behaviour. 300d10910e6SBruce M Simpson 301d10910e6SBruce M Simpson For systems administrators, to obtain best performance with 302d10910e6SBruce M Simpson multicast reception and multiple groups, it is always recommended 303d10910e6SBruce M Simpson that a card with a suitably precise hash filter is used. Hash 304d10910e6SBruce M Simpson collisions will still result in the lock being taken within the 305d10910e6SBruce M Simpson transport protocol input path to check group membership. 306d10910e6SBruce M Simpson 307d10910e6SBruce M Simpson If deploying FreeBSD in an environment with IGMP snooping switches, 308d10910e6SBruce M Simpson it is recommended that the net.inet.igmp.sendlocal sysctl remain 309d10910e6SBruce M Simpson enabled; this forces 224.0.0.0/24 group membership to be announced 310d10910e6SBruce M Simpson via IGMP. 311d10910e6SBruce M Simpson 312d10910e6SBruce M Simpson The size of 'struct igmpstat' has changed; netstat needs to be 313d10910e6SBruce M Simpson recompiled to reflect this. 314d10910e6SBruce M Simpson Bump __FreeBSD_version to 800070. 315d10910e6SBruce M Simpson 316d10910e6SBruce M Simpson20090309: 317a091d2a5SAndrew Thompson libusb20.so.1 is now installed as libusb.so.1 and the ports system 318a091d2a5SAndrew Thompson updated to use it.

With this 498eaeb50d4SDag-Erling Smørgrav upgrade, we've switched to the vendor's default of RSA over 499eaeb50d4SDag-Erling Smørgrav DSA.

The old fts(3) ABI is preserved 62348aaad5fSYaroslav Tykhiy through symbol versioning in libc, so third-party binaries 62448aaad5fSYaroslav Tykhiy using fts(3) should still work, although they will not take 62548aaad5fSYaroslav Tykhiy advantage of the extended types. At the same time, some 62648aaad5fSYaroslav Tykhiy third-party software might fail to build after this change 62748aaad5fSYaroslav Tykhiy due to unportable assumptions made in its source code about 62848aaad5fSYaroslav Tykhiy fts(3) structure members.

Unfortunately, this required the ABI of 65933d3fffaSMarius Strobl PCIOCGETCONF to be broken again in order to be able to 66033d3fffaSMarius Strobl provide backwards compatibility to the old version of that 66133d3fffaSMarius Strobl IOCTL. Thus consumers of PCIOCGETCONF have to be recompiled 66233d3fffaSMarius Strobl again. As for prominent ports this affects neither pciutils 66333d3fffaSMarius Strobl nor xorg-server this time, the hal port needs to be rebuilt 66433d3fffaSMarius Strobl however. 66533d3fffaSMarius Strobl 6663d461febSJulian Elischer20071020: 6673d461febSJulian Elischer The misnamed kthread_create() and friends have been renamed 6683d461febSJulian Elischer to kproc_create() etc. Many of the callers already 6693d461febSJulian Elischer used kproc_start().. 6703d461febSJulian Elischer I will return kthread_create() and friends in a while 6713d461febSJulian Elischer with implementations that actually create threads, not procs. 6723d461febSJulian Elischer Renaming corresponds with version 800002. 6733d461febSJulian Elischer 674c15e0967SKen Smith20071010: 675c15e0967SKen Smith RELENG_7 branched. 676c15e0967SKen Smith 677dbc6a2cfSDavid E.

If you update across this point and 928b5db8ef0SRemko Lodder your metadata is converted for you, you will not be easily 929b5db8ef0SRemko Lodder able to downgrade since the /boot/kernel.old/geom_mirror.ko 930b5db8ef0SRemko Lodder kernel module will be unable to read the v4 metadata.

The new adjkerntz utility uses the new 10249f8d2f6cSGiorgos Keramidas sysctl names and sysctlbyname() calls, so it may be impossible 10259f8d2f6cSGiorgos Keramidas to run an old /sbin/adjkerntz utility in single-user mode 10269f8d2f6cSGiorgos Keramidas with a new kernel.

Note also that by default puc(4) will use uart(4) 1047ff6a2d00SMarcel Moolenaar and not sio(4) for serial ports because interrupt handling has 1048ff6a2d00SMarcel Moolenaar been optimized for multi-port serial cards and only uart(4) 1049ff6a2d00SMarcel Moolenaar implements the interface to support it. 1050ff6a2d00SMarcel Moolenaar 1051ff6a2d00SMarcel Moolenaar20060330: 1052ff6a2d00SMarcel Moolenaar The scc(4) driver replaces puc(4) for Serial Communications 1053ff6a2d00SMarcel Moolenaar Controllers (SCCs) like the Siemens SAB82532 and the Zilog 1054ff6a2d00SMarcel Moolenaar Z8530. On sparc64, it is advised to add scc(4) to the kernel 1055ff6a2d00SMarcel Moolenaar configuration to make sure that the serial ports remain 1056ff6a2d00SMarcel Moolenaar functional. 1057ff6a2d00SMarcel Moolenaar 1058c60fab8cSRuslan Ermilov20060317: 1059c60fab8cSRuslan Ermilov Most world/kernel related NO_* build options changed names. 1060c60fab8cSRuslan Ermilov New knobs have common prefixes WITHOUT_*/WITH_* (modelled 1061c60fab8cSRuslan Ermilov after FreeBSD ports) and should be set in /etc/src.conf 1062c60fab8cSRuslan Ermilov (the src.conf(5) manpage is provided). Full backwards 1063c60fab8cSRuslan Ermilov compatibility is maintained for the time being though it's 1064c60fab8cSRuslan Ermilov highly recommended to start moving old options out of the 1065c60fab8cSRuslan Ermilov system-wide /etc/make.conf file into the new /etc/src.conf 1066c60fab8cSRuslan Ermilov while also properly renaming them.

Specifically, if you intend to use WEP encryption 132587c9e370SSam Leffler with an 802.11 device load/configure wlan_wep; if you want to 132687c9e370SSam Leffler use WPA with the ath driver load/configure wlan_tkip, wlan_ccmp, 132787c9e370SSam Leffler and wlan_xauth as required. 132887c9e370SSam Leffler 132971c1c49aSBrian Somers20041213: 133071c1c49aSBrian Somers The behaviour of ppp(8) has changed slightly. If lqr is enabled 133171c1c49aSBrian Somers (``enable lqr''), older versions would revert to LCP ECHO mode on 133271c1c49aSBrian Somers negotiation failure. Now, ``enable echo'' is required for this 133371c1c49aSBrian Somers behaviour. The ppp version number has been bumped to 3.4.2 to 133471c1c49aSBrian Somers reflect the change. 133571c1c49aSBrian Somers 133688046524SSam Leffler20041201: 133788046524SSam Leffler The wlan support has been updated to split the crypto support 133888046524SSam Leffler into separate modules. For static WEP you must configure the 133988046524SSam Leffler wlan_wep module in your system or build and install the module 134088046524SSam Leffler in place where it can be loaded (the kernel will auto-load 134188046524SSam Leffler the module when a wep key is configured). 134288046524SSam Leffler 134388046524SSam Leffler20041201: 134488046524SSam Leffler The ath driver has been updated to split the tx rate control 134588046524SSam Leffler algorithm into a separate module.

From time to time in the 1382a24eff53SWarner Losh past there have been problems using -j with buildworld and/or 1383a24eff53SWarner Losh installworld. This is especially true when upgrading between 1384a24eff53SWarner Losh "distant" versions (eg one that cross a major release boundary 1385a24eff53SWarner Losh or several minor releases, or when several months have passed 1386a24eff53SWarner Losh on the -current branch). 1387a24eff53SWarner Losh 13885780f3baSWarner Losh Sometimes, obscure build problems are the result of environment 13895780f3baSWarner Losh poisoning. This can happen because the make utility reads its 13905780f3baSWarner Losh environment when searching for values for global variables. 13915780f3baSWarner Losh To run your build attempts in an "environmental clean room", 13925780f3baSWarner Losh prefix all make commands with 'env -i '. See the env(1) manual 13935780f3baSWarner Losh page for more details. 13945780f3baSWarner Losh 1395081ff8acSDoug Barton When upgrading from one major version to another it is generally 1396081ff8acSDoug Barton best to upgrade to the latest code in the currently installed branch 1397081ff8acSDoug Barton first, then do an upgrade to the new branch. This is the best-tested 1398081ff8acSDoug Barton upgrade path, and has the highest probability of being successful. 1399081ff8acSDoug Barton Please try this approach before reporting problems with a major 1400081ff8acSDoug Barton version upgrade. 1401081ff8acSDoug Barton 1402dc0dbf5cSWarner Losh To build a kernel 1403dc0dbf5cSWarner Losh ----------------- 1404ba01eb20SWarner Losh If you are updating from a prior version of FreeBSD (even one just 14051cf0ef11SDavid E.

Attempting to do it by hand is not recommended and those 1517a6cd4f9dSWarner Losh that pursue this avenue should read this file carefully, as well 1518a6cd4f9dSWarner Losh as the archives of freebsd-current and freebsd-hackers mailing lists 1519a6cd4f9dSWarner Losh for potential gotchas. 1520a6cd4f9dSWarner Losh 1521835284beSWarner Losh [5] Usually this step is a noop. However, from time to time 1522835284beSWarner Losh you may need to do this if you get unknown user in the following 1523835284beSWarner Losh step. It never hurts to do it all the time. You may need to 1524835284beSWarner Losh install a new mergemaster (cd src/usr.sbin/mergemaster && make 1525835284beSWarner Losh install) after the buildworld before this step if you last updated 1526835284beSWarner Losh from current before 20020224 or from -stable before 20020408. 1527835284beSWarner Losh 1528c74fe6afSWarner Losh [8] In order to have a kernel that can run the 4.x binaries 1529c74fe6afSWarner Losh needed to do an installworld, you must include the COMPAT_FREEBSD4 1530c74fe6afSWarner Losh option in your kernel. Failure to do so may leave you with a system 153165f1be68SGleb Smirnoff that is hard to boot to recover. A similar kernel option COMPAT_FREEBSD5 153265f1be68SGleb Smirnoff is required to run the 5.x binaries on more recent kernels. 1533c74fe6afSWarner Losh 1534e5dc5f61SWarner Losh Make sure that you merge any new devices from GENERIC since the 1535e5dc5f61SWarner Losh last time you updated your kernel config file. 1536e5dc5f61SWarner Losh 153721c075eaSWarner Losh [9] When checking out sources, you must include the -P flag to have 1538e5dc5f61SWarner Losh cvs prune empty directories. 1539e5dc5f61SWarner Losh 1540e5dc5f61SWarner Losh If CPUTYPE is defined in your /etc/make.conf, make sure to use the 1541e5dc5f61SWarner Losh "?=" instead of the "=" assignment operator, so that buildworld can 1542e5dc5f61SWarner Losh override the CPUTYPE if it needs to. 1543e5dc5f61SWarner Losh 1544e5dc5f61SWarner Losh MAKEOBJDIRPREFIX must be defined in an environment variable, and 1545e5dc5f61SWarner Losh not on the command line, or in /etc/make.conf. buildworld will 1546e5dc5f61SWarner Losh warn if it is improperly defined. 1547dc0dbf5cSWarner LoshFORMAT: 1548dc0dbf5cSWarner Losh 1549f699bbbbSMark OvensThis file contains a list, in reverse chronological order, of major 15501fc1a0dcSWarner Loshbreakages in tracking -current.
