These features attempt to detect incorrect use of 15456b5dd8SWarner Losh system primitives, and encourage loud failure through extra sanity 16456b5dd8SWarner Losh checking and fail stop semantics. They also substantially impact 17456b5dd8SWarner Losh system performance. If you want to do performance measurement, 18456b5dd8SWarner Losh benchmarking, and optimization, you'll want to turn them off. This 19456b5dd8SWarner Losh includes various WITNESS- related kernel options, INVARIANTS, malloc 20456b5dd8SWarner Losh debugging flags in userland, and various verbose features in the 21456b5dd8SWarner Losh kernel. Many developers choose to disable these features on build 22456b5dd8SWarner Losh machines to maximize performance. (To disable malloc debugging, run 236bea5c3cSTom Rhodes ln -s aj /etc/malloc.conf.) 24efc06131SSam Leffler 25*d1675e38SJason Evans20120417: 26*d1675e38SJason Evans The malloc(3) implementation embedded in libc now uses sources imported 27*d1675e38SJason Evans as contrib/jemalloc. The most disruptive API change is to 28*d1675e38SJason Evans /etc/malloc.conf. If your system has an old-style /etc/malloc.conf, 29*d1675e38SJason Evans delete it prior to installworld, and optionally re-create it using the 30*d1675e38SJason Evans new format after rebooting. See malloc.conf(5) for details 31*d1675e38SJason Evans (specifically the TUNING section and the "opt.*" entries in the MALLCTL 32*d1675e38SJason Evans NAMESPACE section). 33*d1675e38SJason Evans 3484db023eSJuli Mallett20120328: 3584db023eSJuli Mallett Big-endian MIPS TARGET_ARCH values no longer end in "eb". mips64eb 3684db023eSJuli Mallett is now spelled mips64. mipsn32eb is now spelled mipsn32. mipseb is 3784db023eSJuli Mallett now spelled mips. This is to aid compatibility with third-party 3884db023eSJuli Mallett software that expects this naming scheme in uname(3). Little-endian 3984db023eSJuli Mallett settings are unchanged. 4084db023eSJuli Mallett 419c170fd1SAttilio Rao20120306: 429c170fd1SAttilio Rao Disable by default the option VFS_ALLOW_NONMPSAFE for all supported 439c170fd1SAttilio Rao platforms. 449c170fd1SAttilio Rao 45c7e41c8bSMikolaj Golub20120229: 46c7e41c8bSMikolaj Golub Now unix domain sockets behave "as expected" on nullfs(5). Previously 47c7e41c8bSMikolaj Golub nullfs(5) did not pass through all behaviours to the underlying layer, 48c7e41c8bSMikolaj Golub as a result if we bound to a socket on the lower layer we could connect 49c7e41c8bSMikolaj Golub only to the lower path; if we bound to the upper layer we could connect 50c7e41c8bSMikolaj Golub only to the upper path. The new behavior is one can connect to both the 51c7e41c8bSMikolaj Golub lower and the upper paths regardless what layer path one binds to. 52c7e41c8bSMikolaj Golub 53ca1672daSBjoern A. Zeeb20120211: 54ca1672daSBjoern A. Zeeb The getifaddrs upgrade path broken with 20111215 has been restored. 55ca1672daSBjoern A. Zeeb If you have upgraded in between 20111215 and 20120209 you need to 56ca1672daSBjoern A. Zeeb recompile libc again with your kernel. You still need to recompile 57ca1672daSBjoern A. Zeeb world to be able to configure CARP but this restriction already 58ca1672daSBjoern A. Zeeb comes from 20111215. 59ca1672daSBjoern A. Zeeb 60e0e0f25bSDoug Barton20120114: 61e0e0f25bSDoug Barton The set_rcvar() function has been removed from /etc/rc.subr. All 62e0e0f25bSDoug Barton base and ports rc.d scripts have been updated, so if you have a 63e0e0f25bSDoug Barton port installed with a script in /usr/local/etc/rc.d you can either 64e0e0f25bSDoug Barton hand-edit the rcvar= line, or reinstall the port. 65e0e0f25bSDoug Barton 665d482324SDoug Barton An easy way to handle the mass-update of /etc/rc.d: 675d482324SDoug Barton rm /etc/rc.d/* && mergemaster -i 685d482324SDoug Barton 6990d82653SAndriy Gapon20120109: 7090d82653SAndriy Gapon panic(9) now stops other CPUs in the SMP systems, disables interrupts 7190d82653SAndriy Gapon on the current CPU and prevents other threads from running. 7290d82653SAndriy Gapon This behavior can be reverted using the kern.stop_scheduler_on_panic 7390d82653SAndriy Gapon tunable/sysctl. 7490d82653SAndriy Gapon The new behavior can be incompatible with kern.sync_on_panic. 7590d82653SAndriy Gapon 7608b68b0eSGleb Smirnoff20111215: 7708b68b0eSGleb Smirnoff The carp(4) facility has been changed significantly. Configuration 7808b68b0eSGleb Smirnoff of the CARP protocol via ifconfig(8) has changed, as well as format 7908b68b0eSGleb Smirnoff of CARP events submitted to devd(8) has changed. See manual pages 8008b68b0eSGleb Smirnoff for more information. The arpbalance feature of carp(4) is currently 8108b68b0eSGleb Smirnoff not supported anymore. 8208b68b0eSGleb Smirnoff 8308b68b0eSGleb Smirnoff Size of struct in_aliasreq, struct in6_aliasreq has changed. User 8408b68b0eSGleb Smirnoff utilities using SIOCAIFADDR, SIOCAIFADDR_IN6, e.g. ifconfig(8), 8508b68b0eSGleb Smirnoff need to be recompiled. 8608b68b0eSGleb Smirnoff 87d5d131eeSJaakko Heinonen20111122: 88d5d131eeSJaakko Heinonen The acpi_wmi(4) status device /dev/wmistat has been renamed to 89d5d131eeSJaakko Heinonen /dev/wmistat0. 90d5d131eeSJaakko Heinonen 91ed1f6dc2SAttilio Rao20111108: 92ed1f6dc2SAttilio Rao The option VFS_ALLOW_NONMPSAFE option has been added in order to 93ed1f6dc2SAttilio Rao explicitely support non-MPSAFE filesystems. 94ed1f6dc2SAttilio Rao It is on by default for all supported platform at this present 95ed1f6dc2SAttilio Rao time. 96ed1f6dc2SAttilio Rao 97a9ab459bSMarius Strobl20111101: 98a9ab459bSMarius Strobl The broken amd(4) driver has been replaced with esp(4) in the amd64, 99a9ab459bSMarius Strobl i386 and pc98 GENERIC kernel configuration files. 100a9ab459bSMarius Strobl 101e59e2d8eSNathan Whitehorn20110930: 102e59e2d8eSNathan Whitehorn sysinstall has been removed 103e59e2d8eSNathan Whitehorn 1048a3b6cc1SKen Smith20110923: 1058a3b6cc1SKen Smith The stable/9 branch created in subversion. This corresponds to the 1068a3b6cc1SKen Smith RELENG_9 branch in CVS. 1078a3b6cc1SKen Smith 1084d30adc4SRick Macklem20110913: 1094d30adc4SRick Macklem This commit modifies vfs_register() so that it uses a hash 1104d30adc4SRick Macklem calculation to set vfc_typenum, which is enabled by default. 1114d30adc4SRick Macklem The first time a system is booted after this change, the 1124d30adc4SRick Macklem vfc_typenum values will change for all file systems. The 1134d30adc4SRick Macklem main effect of this is a change to the NFS server file handles 1144d30adc4SRick Macklem for file systems that use vfc_typenum in their fsid, such as ZFS. 1154d30adc4SRick Macklem It will, however, prevent vfc_typenum from changing when file 1164d30adc4SRick Macklem systems are loaded in a different order for subsequent reboots. 1174d30adc4SRick Macklem To disable this, you can set vfs.typenumhash=0 in /boot/loader.conf 1184d30adc4SRick Macklem until you are ready to remount all NFS clients after a reboot. 1194d30adc4SRick Macklem 1207596eb48SKonstantin Belousov20110828: 1217596eb48SKonstantin Belousov Bump the shared library version numbers for libraries that 1227596eb48SKonstantin Belousov do not use symbol versioning, have changed the ABI compared 1237596eb48SKonstantin Belousov to stable/8 and which shared library version was not bumped. 1247596eb48SKonstantin Belousov Done as part of 9.0-RELEASE cycle. 1257596eb48SKonstantin Belousov 12674d0c46dSRobert Watson20110815: 12774d0c46dSRobert Watson During the merge of Capsicum features, the fget(9) KPI was modified. 12874d0c46dSRobert Watson This may require the rebuilding of out-of-tree device drivers -- 12974d0c46dSRobert Watson issues have been reported specifically with the nVidia device driver. 13074d0c46dSRobert Watson __FreeBSD_version is bumped to 900041. 13174d0c46dSRobert Watson 13274d0c46dSRobert Watson Also, there is a period between 20110811 and 20110814 where the 13374d0c46dSRobert Watson special devices /dev/{stdin,stdout,stderr} did not work correctly. 13474d0c46dSRobert Watson Building world from a kernel during that window may not work. 13574d0c46dSRobert Watson 136e0bfbfceSBjoern A. Zeeb20110628: 137e0bfbfceSBjoern A. Zeeb The packet filter (pf) code has been updated to OpenBSD 4.5. 138e0bfbfceSBjoern A. Zeeb You need to update userland tools to be in sync with kernel. 13970d57756SBjoern A. Zeeb This update breaks backward compatibility with earlier pfsync(4) 14070d57756SBjoern A. Zeeb versions. Care must be taken when updating redundant firewall setups. 141e0bfbfceSBjoern A. Zeeb 142234dab4aSAndriy Gapon20110608: 143234dab4aSAndriy Gapon The following sysctls and tunables are retired on x86 platforms: 144234dab4aSAndriy Gapon machdep.hlt_cpus 145234dab4aSAndriy Gapon machdep.hlt_logical_cpus 146234dab4aSAndriy Gapon The following sysctl is retired: 147234dab4aSAndriy Gapon machdep.hyperthreading_allowed 148234dab4aSAndriy Gapon The sysctls were supposed to provide a way to dynamically offline and 149234dab4aSAndriy Gapon online selected CPUs on x86 platforms, but the implementation has not 150234dab4aSAndriy Gapon been reliable especially with SCHED_ULE scheduler. 151234dab4aSAndriy Gapon machdep.hyperthreading_allowed tunable is still available to ignore 152234dab4aSAndriy Gapon hyperthreading CPUs at OS level. 153234dab4aSAndriy Gapon Individual CPUs can be disabled using hint.lapic.X.disabled tunable, 154234dab4aSAndriy Gapon where X is an APIC ID of a CPU. Be advised, though, that disabling 155234dab4aSAndriy Gapon CPUs in non-uniform fashion will result in non-uniform topology and 156234dab4aSAndriy Gapon may lead to sub-optimal system performance with SCHED_ULE, which is 157234dab4aSAndriy Gapon a default scheduler. 158234dab4aSAndriy Gapon 159f0fcb367SAttilio Rao20110607: 160f0fcb367SAttilio Rao cpumask_t type is retired and cpuset_t is used in order to describe 161f0fcb367SAttilio Rao a mask of CPUs. 162f0fcb367SAttilio Rao 163ec49fe39SBjoern A.

The new client is compiled into the 1954309e17aSRick Macklem kernel with "options NFSCL" and this is needed for diskless root 1964309e17aSRick Macklem file systems. The GENERIC kernel configs have been changed to use 1974309e17aSRick Macklem NFSCL and NFSD (the new server) instead of NFSCLIENT and NFSSERVER. 1984309e17aSRick Macklem To use the regular/old client, you can "mount -t oldnfs ...". For 1994309e17aSRick Macklem a diskless root file system, you must also include a line like: 2004309e17aSRick Macklem 2014309e17aSRick Macklem vfs.root.mountfrom="oldnfs:" 2024309e17aSRick Macklem 2034309e17aSRick Macklem in the boot/loader.conf on the root fs on the NFS server to make 2044309e17aSRick Macklem a diskless root fs use the old client. 2054309e17aSRick Macklem 20697b53e36SAlexander Motin20110424: 20797b53e36SAlexander Motin The GENERIC kernels for all architectures now default to the new 20897b53e36SAlexander Motin CAM-based ATA stack. It means that all legacy ATA drivers were 20997b53e36SAlexander Motin removed and replaced by respective CAM drivers. If you are using 21097b53e36SAlexander Motin ATA device names in /etc/fstab or other places, make sure to update 21197b53e36SAlexander Motin them respectively (adX -> adaY, acdX -> cdY, afdX -> daY, astX -> saY, 212ddfddf12SAlexander Motin where 'Y's are the sequential numbers starting from zero for each type 213ddfddf12SAlexander Motin in order of detection, unless configured otherwise with tunables, 2140d307e09SAlexander Motin see cam(4)). There will be symbolic links created in /dev/ to map 2150d307e09SAlexander Motin old adX devices to the respective adaY. They should provide basic 2160d307e09SAlexander Motin compatibility for file systems mounting in most cases, but they do 2170d307e09SAlexander Motin not support old user-level APIs and do not have respective providers 2180d307e09SAlexander Motin in GEOM. Consider using updated management tools with new device names. 2190d307e09SAlexander Motin 2200d307e09SAlexander Motin It is possible to load devices ahci, ata, siis and mvs as modules, 2210d307e09SAlexander Motin but option ATA_CAM should remain in kernel configuration to make ata 2220d307e09SAlexander Motin module work as CAM driver supporting legacy ATA controllers. Device ata 2230d307e09SAlexander Motin still can be used in modular fashion (atacore + ...). Modules atadisk 2240d307e09SAlexander Motin and atapi* are not used and won't affect operation in ATA_CAM mode. 2255d4ac622SAlexander Motin Note that to use CAM-based ATA kernel should include CAM devices 2265d4ac622SAlexander Motin scbus, pass, da (or explicitly ada), cd and optionally others. All of 2275d4ac622SAlexander Motin them are parts of the cam module. 22897b53e36SAlexander Motin 22997b53e36SAlexander Motin ataraid(4) functionality is now supported by the RAID GEOM class. 23097b53e36SAlexander Motin To use it you can load geom_raid kernel module and use graid(8) tool 23197b53e36SAlexander Motin for management. Instead of /dev/arX device names, use /dev/raid/rX. 23297b53e36SAlexander Motin 23397b53e36SAlexander Motin No kernel config options or code have been removed, so if a problem 23497b53e36SAlexander Motin arises, please report it and optionally revert to the old ATA stack. 23597b53e36SAlexander Motin In order to do it you can remove from the kernel config: 23697b53e36SAlexander Motin options ATA_CAM 23797b53e36SAlexander Motin device ahci 23897b53e36SAlexander Motin device mvs 23997b53e36SAlexander Motin device siis 24097b53e36SAlexander Motin , and instead add back: 24197b53e36SAlexander Motin device atadisk # ATA disk drives 24297b53e36SAlexander Motin device ataraid # ATA RAID drives 24397b53e36SAlexander Motin device atapicd # ATAPI CDROM drives 24497b53e36SAlexander Motin device atapifd # ATAPI floppy drives 24597b53e36SAlexander Motin device atapist # ATAPI tape drives 24697b53e36SAlexander Motin 2472a85df8cSRick Macklem20110423: 2482a85df8cSRick Macklem The default NFS server has been changed to the new server, which 2492a85df8cSRick Macklem was referred to as the experimental server. If you need to switch 2502a85df8cSRick Macklem back to the old NFS server, you must now put the "-o" option on 2512a85df8cSRick Macklem both the mountd and nfsd commands. This can be done using the 2522a85df8cSRick Macklem mountd_flags and nfs_server_flags rc.conf variables until an 2532a85df8cSRick Macklem update to the rc scripts is committed, which is coming soon. 2542a85df8cSRick Macklem 25566f3a31fSDimitry Andric20110418: 25666f3a31fSDimitry Andric The GNU Objective-C runtime library (libobjc), and other Objective-C 25766f3a31fSDimitry Andric related components have been removed from the base system.

The equivalent functionality 29713434232SMatthew D Fleming is now available using kern_yield(curthread->td_user_pri). 29813434232SMatthew D Fleming The function remains undocumented. 29913434232SMatthew D Fleming 3004c8945a0SNathan Whitehorn20110112: 3011eae8811SMatthew D Fleming A SYSCTL_[ADD_]UQUAD was added for unsigned uint64_t pointers, 3021eae8811SMatthew D Fleming symmetric with the existing SYSCTL_[ADD_]QUAD. Type checking 3031eae8811SMatthew D Fleming for scalar sysctls is defined but disabled. Code that needs 3041eae8811SMatthew D Fleming UQUAD to pass the type checking that must compile on older 3051eae8811SMatthew D Fleming systems where the define is not present can check against 3061eae8811SMatthew D Fleming __FreeBSD_version >= 900030. 3071eae8811SMatthew D Fleming 3084c8945a0SNathan Whitehorn The system dialog(1) has been replaced with a new version previously 3094c8945a0SNathan Whitehorn in ports as devel/cdialog. dialog(1) is mostly command-line compatible 3104c8945a0SNathan Whitehorn with the previous version, but the libdialog associated with it has 3114c8945a0SNathan Whitehorn a largely incompatible API. As such, the original version of libdialog 3124c8945a0SNathan Whitehorn will be kept temporarily as libodialog, until its base system consumers 3134c8945a0SNathan Whitehorn are replaced or updated. Bump __FreeBSD_version to 900030. 3144c8945a0SNathan Whitehorn 315e4f64803SWarner Losh20110103: 316e4f64803SWarner Losh If you are trying to run make universe on a -stable system, and you get 317e4f64803SWarner Losh the following warning: 3187b57aa33SRebecca Cran "Makefile", line 356: "Target architecture for i386/conf/GENERIC 3197b57aa33SRebecca Cran unknown. config(8) likely too old." 320e4f64803SWarner Losh or something similar to it, then you must upgrade your -stable system 321e4f64803SWarner Losh to 8.2-Release or newer (really, any time after r210146 7/15/2010 in 322e4f64803SWarner Losh stable/8) or build the config from the latest stable/8 branch and 323e4f64803SWarner Losh install it on your system. 324e4f64803SWarner Losh 325e4f64803SWarner Losh Prior to this date, building a current universe on 8-stable system from 326e4f64803SWarner Losh between 7/15/2010 and 1/2/2011 would result in a weird shell parsing 3277b57aa33SRebecca Cran error in the first kernel build phase. A new config on those old 3287b57aa33SRebecca Cran systems will fix that problem for older versions of -current. 329e4f64803SWarner Losh 33039bc9de5SLawrence Stewart20101228: 33139bc9de5SLawrence Stewart The TCP stack has been modified to allow Khelp modules to interact with 33239bc9de5SLawrence Stewart it via helper hook points and store per-connection data in the TCP 33339bc9de5SLawrence Stewart control block. Bump __FreeBSD_version to 900029. User space tools that 33439bc9de5SLawrence Stewart rely on the size of struct tcpcb in tcp_var.h (e.g. sockstat) need to 33539bc9de5SLawrence Stewart be recompiled. 33639bc9de5SLawrence Stewart 337efd4fc3fSMarius Strobl20101114: 338efd4fc3fSMarius Strobl Generic IEEE 802.3 annex 31B full duplex flow control support has been 339efd4fc3fSMarius Strobl added to mii(4) and bge(4), bce(4), msk(4), nfe(4) and stge(4) along 340efd4fc3fSMarius Strobl with brgphy(4), e1000phy(4) as well as ip1000phy() have been converted 341efd4fc3fSMarius Strobl to take advantage of it instead of using custom implementations. This 342efd4fc3fSMarius Strobl means that these drivers now no longer unconditionally advertise 343efd4fc3fSMarius Strobl support for flow control but only do so if flow control is a selected 344efd4fc3fSMarius Strobl media option. This was implemented in the generic support that way in 345efd4fc3fSMarius Strobl order to allow flow control to be switched on and off via ifconfig(8) 346efd4fc3fSMarius Strobl with the PHY specific default to typically off in order to protect 347efd4fc3fSMarius Strobl from unwanted effects. Consequently, if you used flow control with 348efd4fc3fSMarius Strobl one of the above mentioned drivers you now need to explicitly enable 349efd4fc3fSMarius Strobl it, for example via: 350efd4fc3fSMarius Strobl ifconfig bge0 media auto mediaopt flowcontrol 351efd4fc3fSMarius Strobl 352efd4fc3fSMarius Strobl Along with the above mentioned changes generic support for setting 353efd4fc3fSMarius Strobl 1000baseT master mode also has been added and brgphy(4), ciphy(4), 354efd4fc3fSMarius Strobl e1000phy(4) as well as ip1000phy(4) have been converted to take 355efd4fc3fSMarius Strobl advantage of it. This means that these drivers now no longer take the 356efd4fc3fSMarius Strobl link0 parameter for selecting master mode but the master media option 357efd4fc3fSMarius Strobl has to be used instead, for example like in the following: 358efd4fc3fSMarius Strobl ifconfig bge0 media 1000baseT mediaopt full-duplex,master 359efd4fc3fSMarius Strobl 360efd4fc3fSMarius Strobl Selection of master mode now is also available with all other PHY 361efd4fc3fSMarius Strobl drivers supporting 1000baseT. 362efd4fc3fSMarius Strobl 363dbc42409SLawrence Stewart20101111: 364dbc42409SLawrence Stewart The TCP stack has received a significant update to add support for 365dbc42409SLawrence Stewart modularised congestion control and generally improve the clarity of 366dbc42409SLawrence Stewart congestion control decisions. Bump __FreeBSD_version to 900025. User 367dbc42409SLawrence Stewart space tools that rely on the size of struct tcpcb in tcp_var.h (e.g. 368dbc42409SLawrence Stewart sockstat) need to be recompiled. 369dbc42409SLawrence Stewart 370fd77eab9SGordon Tetlow20101002: 371fd77eab9SGordon Tetlow The man(1) utility has been replaced by a new version that no longer 372fd77eab9SGordon Tetlow uses /etc/manpath.config.

A value 394d3a8a8b9SHiroki Sato "ipv4_prefer", "ipv6_prefer" or "AUTO" can be specified. The 395d3a8a8b9SHiroki Sato default is "AUTO". 396d3a8a8b9SHiroki Sato 397d3a8a8b9SHiroki Sato The $ipv6_activate_all_interfaces specifies whether IFDISABLED 398d3a8a8b9SHiroki Sato flag (see an entry of 20090926) is set on an interface with no 399d3a8a8b9SHiroki Sato corresponding $ifconfig_IF_ipv6 line. The default is "NO" for 400d3a8a8b9SHiroki Sato security reason. If you want IPv6 link-local address on all 401d3a8a8b9SHiroki Sato interfaces by default, set this to "YES". 402d3a8a8b9SHiroki Sato 403d3a8a8b9SHiroki Sato The old ipv6_prefer="YES" is equivalent to 404d3a8a8b9SHiroki Sato ipv6_activate_all_interfaces="YES" and 405d3a8a8b9SHiroki Sato ip6addrctl_policy="ipv6_prefer". 406d3a8a8b9SHiroki Sato 407d3a8a8b9SHiroki Sato20100913: 408d69eb520SRui Paulo DTrace has grown support for userland tracing. Due to this, DTrace is 409d69eb520SRui Paulo now i386 and amd64 only. 410d69eb520SRui Paulo dtruss(1) is now installed by default on those systems and a new 411d69eb520SRui Paulo kernel module is needed for userland tracing: fasttrap. 412d69eb520SRui Paulo No changes to your kernel config file are necessary to enable 413d69eb520SRui Paulo userland tracing, but you might consider adding 'STRIP=' and 414d69eb520SRui Paulo 'CFLAGS+=-fno-omit-frame-pointer' to your make.conf if you want 415d69eb520SRui Paulo to have informative userland stack traces in DTrace (ustack). 416d69eb520SRui Paulo 41740650455SRui Paulo20100725: 41840650455SRui Paulo The acpi_aiboost(4) driver has been removed in favor of the new 41940650455SRui Paulo aibs(4) driver.

It is completely BSD licensed, highly GNU-compatible, uses 4244dc88ebeSGabor Kovesdan less memory than its GNU counterpart and has a small codebase. 4254dc88ebeSGabor Kovesdan However, it is slower than its GNU counterpart, which is mostly 4264dc88ebeSGabor Kovesdan noticeable for larger searches, for smaller ones it is measurable 4274dc88ebeSGabor Kovesdan but not significant. The reason is complex, the most important factor 4284dc88ebeSGabor Kovesdan is that we lack a modern and efficient regex library and GNU 4294dc88ebeSGabor Kovesdan overcomes this by optimizing the searches internally. Future work 4304dc88ebeSGabor Kovesdan on improving the regex performance is planned, for the meantime, 4314dc88ebeSGabor Kovesdan users that need better performance, can build GNU grep instead by 4324dc88ebeSGabor Kovesdan setting the WITH_GNU_GREP knob. 4332965a453SKip Macy 4348fc25799SMartin Matuska20100713: 435c3e289e1SNathan Whitehorn Due to the import of powerpc64 support, all existing powerpc kernel 436c3e289e1SNathan Whitehorn configuration files must be updated with a machine directive like this: 437c3e289e1SNathan Whitehorn machine powerpc powerpc 438c3e289e1SNathan Whitehorn 439c3e289e1SNathan Whitehorn In addition, an updated config(8) is required to build powerpc kernels 440c3e289e1SNathan Whitehorn after this change. 441c3e289e1SNathan Whitehorn 442c3e289e1SNathan Whitehorn20100713: 4438fc25799SMartin Matuska A new version of ZFS (version 15) has been merged to -HEAD. 4448fc25799SMartin Matuska This version uses a python library for the following subcommands: 4458fc25799SMartin Matuska zfs allow, zfs unallow, zfs groupspace, zfs userspace. 4468fc25799SMartin Matuska For full functionality of these commands the following port must 4478fc25799SMartin Matuska be installed: sysutils/py-zfs 4488fc25799SMartin Matuska 4492965a453SKip Macy20100429: 4502965a453SKip Macy 'vm_page's are now hashed by physical address to an array of mutexes. 4512965a453SKip Macy Currently this is only used to serialize access to hold_count.

All kernel 469841c0c7eSNathan Whitehorn configurations on amd64 and ia64 platforms using these options must 470841c0c7eSNathan Whitehorn be modified accordingly. 471841c0c7eSNathan Whitehorn 472279d8efeSEd Schouten20100113: 473279d8efeSEd Schouten The utmp user accounting database has been replaced with utmpx, 474279d8efeSEd Schouten the user accounting interface standardized by POSIX. 475279d8efeSEd Schouten Unfortunately the semantics of utmp and utmpx don't match, 476279d8efeSEd Schouten making it practically impossible to support both interfaces. 477279d8efeSEd Schouten The user accounting database is used by tools like finger(1), 478279d8efeSEd Schouten last(1), talk(1), w(1) and ac(8). 479279d8efeSEd Schouten 480279d8efeSEd Schouten All applications in the base system use utmpx.

The changes are the following: 5472e77c5abSHiroki Sato 5482e77c5abSHiroki Sato 1. To use IPv6, simply define $ifconfig_IF_ipv6 like $ifconfig_IF 5492e77c5abSHiroki Sato for IPv4. For aliases, $ifconfig_IF_aliasN should be used. 5502e77c5abSHiroki Sato Note that both variables need the "inet6" keyword at the head. 5512e77c5abSHiroki Sato 5522e77c5abSHiroki Sato Do not set $ipv6_network_interfaces manually if you do not 5532e77c5abSHiroki Sato understand what you are doing. It is not needed in most cases. 5542e77c5abSHiroki Sato 5552e77c5abSHiroki Sato $ipv6_ifconfig_IF and $ipv6_ifconfig_IF_aliasN still work, but 5562e77c5abSHiroki Sato they are obsolete. 5572e77c5abSHiroki Sato 5582e77c5abSHiroki Sato 2. $ipv6_enable is obsolete. Use $ipv6_prefer and 5592e77c5abSHiroki Sato "inet6 accept_rtadv" keyword in ifconfig(8) instead. 5602e77c5abSHiroki Sato 5612e77c5abSHiroki Sato If you define $ipv6_enable=YES, it means $ipv6_prefer=YES and 5622e77c5abSHiroki Sato all configured interfaces have "inet6 accept_rtadv" in the 5632e77c5abSHiroki Sato $ifconfig_IF_ipv6. These are for backward compatibility. 5642e77c5abSHiroki Sato 5652e77c5abSHiroki Sato 3. A new variable $ipv6_prefer has been added. If NO, IPv6 5662e77c5abSHiroki Sato functionality of interfaces with no corresponding 5672e77c5abSHiroki Sato $ifconfig_IF_ipv6 is disabled by using "inet6 ifdisabled" flag, 5682e77c5abSHiroki Sato and the default address selection policy of ip6addrctl(8) 5692e77c5abSHiroki Sato is the IPv4-preferred one (see rc.d/ip6addrctl for more details). 5702e77c5abSHiroki Sato Note that if you want to configure IPv6 functionality on the 5712e77c5abSHiroki Sato disabled interfaces after boot, first you need to clear the flag by 5722e77c5abSHiroki Sato using ifconfig(8) like: 5732e77c5abSHiroki Sato 5742e77c5abSHiroki Sato ifconfig em0 inet6 -ifdisabled 5752e77c5abSHiroki Sato 5762e77c5abSHiroki Sato If YES, the default address selection policy is set as 5772e77c5abSHiroki Sato IPv6-preferred. 5782e77c5abSHiroki Sato 5792e77c5abSHiroki Sato The default value of $ipv6_prefer is NO. 5802e77c5abSHiroki Sato 5812e77c5abSHiroki Sato 4. If your system need to receive Router Advertisement messages, 5822e77c5abSHiroki Sato define "inet6 accept_rtadv" in $ifconfig_IF_ipv6. The rc(8) 5832e77c5abSHiroki Sato scripts automatically invoke rtsol(8) when the interface becomes 5842e77c5abSHiroki Sato UP. The Router Advertisement messages are used for SLAAC 5852e77c5abSHiroki Sato (State-Less Address AutoConfiguration). 5862e77c5abSHiroki Sato 587350036a0SRui Paulo20090922: 588350036a0SRui Paulo 802.11s D3.03 support was committed.

Zeeb 669838d9858SBrooks Davis20090619: 670456b5dd8SWarner Losh NGROUPS_MAX and NGROUPS have been increased from 16 to 1023 and 1024 671456b5dd8SWarner Losh respectively. As long as no more than 16 groups per process are used, 672456b5dd8SWarner Losh no changes should be visible. When more than 16 groups are used, old 673456b5dd8SWarner Losh binaries may fail if they call getgroups() or getgrouplist() with 674456b5dd8SWarner Losh statically sized storage. Recompiling will work around this, but 675456b5dd8SWarner Losh applications should be modified to use dynamically allocated storage 676456b5dd8SWarner Losh for group arrays as POSIX.1-2008 does not cap an implementation's 677456b5dd8SWarner Losh number of supported groups at NGROUPS_MAX+1 as previous versions did. 678838d9858SBrooks Davis 679456b5dd8SWarner Losh NFS and portalfs mounts may also be affected as the list of groups is 680456b5dd8SWarner Losh truncated to 16. Users of NFS who use more than 16 groups, should 681456b5dd8SWarner Losh take care that negative group permissions are not used on the exported 682456b5dd8SWarner Losh file systems as they will not be reliable unless a GSSAPI based 683456b5dd8SWarner Losh authentication method is used. 684838d9858SBrooks Davis 685651175c9SAttilio Rao20090616: 686456b5dd8SWarner Losh The compiling option ADAPTIVE_LOCKMGRS has been introduced.

VIMAGE hooks are in but not yet used. 77533cde130SBruce M Simpson The implementation of SSM within FreeBSD's IPv6 stack closely 77633cde130SBruce M Simpson follows the IPv4 implementation. 77733cde130SBruce M Simpson 77833cde130SBruce M Simpson For kernel developers: 77933cde130SBruce M Simpson 78033cde130SBruce M Simpson * The most important changes are that the ip6_output() and 78133cde130SBruce M Simpson ip6_input() paths no longer take the IN6_MULTI_LOCK, 78233cde130SBruce M Simpson and this lock has been downgraded to a non-recursive mutex. 78333cde130SBruce M Simpson 78433cde130SBruce M Simpson * As with the changes to the IPv4 stack to support SSM, filtering 78533cde130SBruce M Simpson of inbound multicast traffic must now be performed by transport 78633cde130SBruce M Simpson protocols within the IPv6 stack. This does not apply to TCP and 78733cde130SBruce M Simpson SCTP, however, it does apply to UDP in IPv6 and raw IPv6. 78833cde130SBruce M Simpson 78933cde130SBruce M Simpson * The KPIs used by IPv6 multicast are similar to those used by 79033cde130SBruce M Simpson the IPv4 stack, with the following differences: 79133cde130SBruce M Simpson * im6o_mc_filter() is analogous to imo_multicast_filter(). 79233cde130SBruce M Simpson * The legacy KAME entry points in6_joingroup and in6_leavegroup() 79333cde130SBruce M Simpson are shimmed to in6_mc_join() and in6_mc_leave() respectively. 79433cde130SBruce M Simpson * IN6_LOOKUP_MULTI() has been deprecated and removed. 79533cde130SBruce M Simpson * IPv6 relies on MLD for the DAD mechanism. KAME's internal KPIs 79633cde130SBruce M Simpson for MLDv1 have an additional 'timer' argument which is used to 79733cde130SBruce M Simpson jitter the initial membership report for the solicited-node 79833cde130SBruce M Simpson multicast membership on-link. 79933cde130SBruce M Simpson * This is not strictly needed for MLDv2, which already jitters 80033cde130SBruce M Simpson its report transmissions. However, the 'timer' argument is 80133cde130SBruce M Simpson preserved in case MLDv1 is active on the interface. 80233cde130SBruce M Simpson 80333cde130SBruce M Simpson * The KAME linked-list based IPv6 membership implementation has 80433cde130SBruce M Simpson been refactored to use a vector similar to that used by the IPv4 80533cde130SBruce M Simpson stack. 80633cde130SBruce M Simpson Code which maintains a list of its own multicast memberships 80733cde130SBruce M Simpson internally, e.g. carp, has been updated to reflect the new 80833cde130SBruce M Simpson semantics. 80933cde130SBruce M Simpson 81033cde130SBruce M Simpson * There is a known Lock Order Reversal (LOR) due to in6_setscope() 81133cde130SBruce M Simpson acquiring the IF_AFDATA_LOCK and being called within ip6_output(). 81233cde130SBruce M Simpson Whilst MLDv2 tries to avoid this otherwise benign LOR, it is an 81333cde130SBruce M Simpson implementation constraint which needs to be addressed in HEAD. 81433cde130SBruce M Simpson 81533cde130SBruce M Simpson For application developers: 81633cde130SBruce M Simpson 81733cde130SBruce M Simpson * The changes are broadly similar to those made for the IPv4 81833cde130SBruce M Simpson stack. 81933cde130SBruce M Simpson 82033cde130SBruce M Simpson * The use of IPv4 and IPv6 multicast socket options on the same 82133cde130SBruce M Simpson socket, using mapped addresses, HAS NOT been tested or supported. 82233cde130SBruce M Simpson 82333cde130SBruce M Simpson * There are a number of issues with the implementation of various 82433cde130SBruce M Simpson IPv6 multicast APIs which need to be resolved in the API surface 82533cde130SBruce M Simpson before the implementation is fully compatible with KAME userland 82633cde130SBruce M Simpson use, and these are mostly to do with interface index treatment. 82733cde130SBruce M Simpson 82833cde130SBruce M Simpson * The literature available discusses the use of either the delta / ASM 82933cde130SBruce M Simpson API with setsockopt(2)/getsockopt(2), or the full-state / ASM API 83033cde130SBruce M Simpson using setsourcefilter(3)/getsourcefilter(3). For more information 83133cde130SBruce M Simpson please refer to RFC 3768, 'Socket Interface Extensions for 83233cde130SBruce M Simpson Multicast Source Filters'. 83333cde130SBruce M Simpson 83433cde130SBruce M Simpson * Applications which use the published RFC 3678 APIs should be fine. 83533cde130SBruce M Simpson 83633cde130SBruce M Simpson For systems administrators: 83733cde130SBruce M Simpson 83833cde130SBruce M Simpson * The mtest(8) utility has been refactored to support IPv6, in 83933cde130SBruce M Simpson addition to IPv4. Interface addresses are no longer accepted 84033cde130SBruce M Simpson as arguments, their names must be used instead. The utility 84133cde130SBruce M Simpson will map the interface name to its first IPv4 address as 84233cde130SBruce M Simpson returned by getifaddrs(3). 84333cde130SBruce M Simpson 84433cde130SBruce M Simpson * The ifmcstat(8) utility has also been updated to print the MLDv2 84533cde130SBruce M Simpson endpoint state and source filter lists via sysctl(3). 84633cde130SBruce M Simpson 84733cde130SBruce M Simpson * The net.inet6.ip6.mcast.loop sysctl may be tuned to 0 to disable 84833cde130SBruce M Simpson loopback of IPv6 multicast datagrams by default; it defaults to 1 84933cde130SBruce M Simpson to preserve the existing behaviour. Disabling multicast loopback is 85033cde130SBruce M Simpson recommended for optimal system performance. 85133cde130SBruce M Simpson 85233cde130SBruce M Simpson * The IPv6 MROUTING code has been changed to examine this sysctl 85333cde130SBruce M Simpson instead of attempting to perform a group lookup before looping 85433cde130SBruce M Simpson back forwarded datagrams. 85533cde130SBruce M Simpson 85633cde130SBruce M Simpson Bump __FreeBSD_version to 800084. 85733cde130SBruce M Simpson 8588b8bf775SRobert Watson20090422: 859131cdffbSMaksim Yevmenkin Implement low-level Bluetooth HCI API. 860131cdffbSMaksim Yevmenkin Bump __FreeBSD_version to 800083. 861131cdffbSMaksim Yevmenkin 8628b8bf775SRobert Watson20090419: 8638b8bf775SRobert Watson The layout of struct malloc_type, used by modules to register new 8648b8bf775SRobert Watson memory allocation types, has changed.

Typical symptoms include (but 89287437955SMaksim Yevmenkin not limited to) duplicated and/or missing characters when 89387437955SMaksim Yevmenkin low level console functions (such as gets) are used while 89487437955SMaksim Yevmenkin interrupts are enabled (for example geli password prompt, 89587437955SMaksim Yevmenkin mountroot prompt etc.).

It 9059a07b548SIvan Voras introduces some changes: 9069a07b548SIvan Voras 9079a07b548SIvan Voras MSDOS/EBR: the devices created from MSDOS extended partition entries 9089a07b548SIvan Voras (EBR) can be named differently than with GEOM_MBR and are now symlinks 9099a07b548SIvan Voras to devices with offset-based names. fstabs may need to be modified. 9109a07b548SIvan Voras 9119a07b548SIvan Voras BSD: the "geometry does not match label" warning is harmless in most 9129a07b548SIvan Voras cases but it points to problems in file system misalignment with 9139a07b548SIvan Voras disk geometry. The "c" partition is now implicit, covers the whole 9149a07b548SIvan Voras top-level drive and cannot be (mis)used by users. 9159a07b548SIvan Voras 9169a07b548SIvan Voras General: Kernel dumps are now not allowed to be written to devices 9179a07b548SIvan Voras whose partition types indicate they are meant to be used for file 9189a07b548SIvan Voras systems (or, in case of MSDOS partitions, as something else than 9199a07b548SIvan Voras the "386BSD" type). 9209a07b548SIvan Voras 9219a07b548SIvan Voras Most of these changes date approximately from 200812. 922781d043cSIvan Voras 923443fc317SBruce M Simpson20090319: 9242b78d306SAndrew Thompson The uscanner(4) driver has been removed from the kernel.

In particular, if_ar, if_sr, and network device 9391df14375SRobert Watson drivers from the old (legacy) USB stack can no longer be built or 9401df14375SRobert Watson used. 9411df14375SRobert Watson 942e667034dSRui Paulo20090313: 9437e06afcaSGabor Kovesdan POSIX.1 Native Language Support (NLS) has been enabled in libc and 9447e06afcaSGabor Kovesdan a bunch of new language catalog files have also been added. 9457e06afcaSGabor Kovesdan This means that some common libc messages are now localized and 9467e06afcaSGabor Kovesdan they depend on the LC_MESSAGES environmental variable. 9477e06afcaSGabor Kovesdan 9487e06afcaSGabor Kovesdan20090313: 949e667034dSRui Paulo The k8temp(4) driver has been renamed to amdtemp(4) since 9508fb1e038SDavid E.

VIMAGE hooks are in but not yet used. 955d10910e6SBruce M Simpson 956d10910e6SBruce M Simpson For kernel developers, the most important changes are that the 957d10910e6SBruce M Simpson ip_output() and ip_input() paths no longer take the IN_MULTI_LOCK(), 958d10910e6SBruce M Simpson and this lock has been downgraded to a non-recursive mutex. 959d10910e6SBruce M Simpson 960d10910e6SBruce M Simpson Transport protocols (UDP, Raw IP) are now responsible for filtering 961d10910e6SBruce M Simpson inbound multicast traffic according to group membership and source 962d10910e6SBruce M Simpson filters. The imo_multicast_filter() KPI exists for this purpose. 963d10910e6SBruce M Simpson Transports which do not use multicast (SCTP, TCP) already reject 964d10910e6SBruce M Simpson multicast by default. Forwarding and receive performance may improve 965d10910e6SBruce M Simpson as a mutex acquisition is no longer needed in the ip_input() 966d10910e6SBruce M Simpson low-level input path. in_addmulti() and in_delmulti() are shimmed 967d10910e6SBruce M Simpson to new KPIs which exist to support SSM in-kernel. 968d10910e6SBruce M Simpson 969d10910e6SBruce M Simpson For application developers, it is recommended that loopback of 970d10910e6SBruce M Simpson multicast datagrams be disabled for best performance, as this 971d10910e6SBruce M Simpson will still cause the lock to be taken for each looped-back 972d10910e6SBruce M Simpson datagram transmission. The net.inet.ip.mcast.loop sysctl may 973d10910e6SBruce M Simpson be tuned to 0 to disable loopback by default; it defaults to 1 974d10910e6SBruce M Simpson to preserve the existing behaviour. 975d10910e6SBruce M Simpson 976d10910e6SBruce M Simpson For systems administrators, to obtain best performance with 977d10910e6SBruce M Simpson multicast reception and multiple groups, it is always recommended 978d10910e6SBruce M Simpson that a card with a suitably precise hash filter is used. Hash 979d10910e6SBruce M Simpson collisions will still result in the lock being taken within the 980d10910e6SBruce M Simpson transport protocol input path to check group membership. 981d10910e6SBruce M Simpson 982d10910e6SBruce M Simpson If deploying FreeBSD in an environment with IGMP snooping switches, 983d10910e6SBruce M Simpson it is recommended that the net.inet.igmp.sendlocal sysctl remain 984d10910e6SBruce M Simpson enabled; this forces 224.0.0.0/24 group membership to be announced 985d10910e6SBruce M Simpson via IGMP. 986d10910e6SBruce M Simpson 987d10910e6SBruce M Simpson The size of 'struct igmpstat' has changed; netstat needs to be 988d10910e6SBruce M Simpson recompiled to reflect this. 989d10910e6SBruce M Simpson Bump __FreeBSD_version to 800070. 990d10910e6SBruce M Simpson 991d10910e6SBruce M Simpson20090309: 992a091d2a5SAndrew Thompson libusb20.so.1 is now installed as libusb.so.1 and the ports system 993a091d2a5SAndrew Thompson updated to use it.

Users should 1190eaeb50d4SDag-Erling Smørgrav follow the usual procedure for verifying host keys before 1191eaeb50d4SDag-Erling Smørgrav accepting the RSA key. 1192eaeb50d4SDag-Erling Smørgrav 1193eaeb50d4SDag-Erling Smørgrav This can be circumvented by setting the "HostKeyAlgorithms" 1194eaeb50d4SDag-Erling Smørgrav option to "ssh-dss,ssh-rsa" in ~/.ssh/config or on the ssh 1195eaeb50d4SDag-Erling Smørgrav command line. 1196eaeb50d4SDag-Erling Smørgrav 1197737d990aSXin LI Please note that the sequence of keys offered for 1198737d990aSXin LI authentication has been changed as well.

This means uart(4) is now the 1205f4d811f0SEd Schouten default serial port driver on those platforms as well. 1206f4d811f0SEd Schouten 1207f4d811f0SEd Schouten To prevent collisions with the sio(4) driver, the uart(4) driver 1208f4d811f0SEd Schouten uses different names for its device nodes. This means the 1209f4d811f0SEd Schouten onboard serial port will now most likely be called "ttyu0" 1210f4d811f0SEd Schouten instead of "ttyd0". You may need to reconfigure applications to 1211f4d811f0SEd Schouten use the new device names. 1212f4d811f0SEd Schouten 1213db96ec0bSEd Schouten When using the serial port as a boot console, be sure to update 1214db96ec0bSEd Schouten /boot/device.hints and /etc/ttys before booting the new kernel. 1215db96ec0bSEd Schouten If you forget to do so, you can still manually specify the hints 1216db96ec0bSEd Schouten at the loader prompt: 1217db96ec0bSEd Schouten 1218db96ec0bSEd Schouten set hint.uart.0.at="isa" 1219db96ec0bSEd Schouten set hint.uart.0.port="0x3F8" 1220db96ec0bSEd Schouten set hint.uart.0.flags="0x10" 1221db96ec0bSEd Schouten set hint.uart.0.irq="4" 1222db96ec0bSEd Schouten boot -s 1223db96ec0bSEd Schouten 1224bdc03b37SMarcel Moolenaar20080609: 1225bdc03b37SMarcel Moolenaar The gpt(8) utility has been removed.

If you experience any problems with Linux binaries 1231a47444d5SRoman Divacky please try to set sysctl compat.linux.osrelease to 2.4.2 and 1232a47444d5SRoman Divacky if it fixes the problem contact emulation mailing list. 1233a47444d5SRoman Divacky 12342e598474SBjoern A. Zeeb20080525: 12352e598474SBjoern A. Zeeb ISDN4BSD (I4B) was removed from the src tree. You may need to 12362e598474SBjoern A.

The underlying device 1248de570baaSSam Leffler is no longer used directly but instead wlanX devices are 1249de570baaSSam Leffler cloned with ifconfig. This requires changes to rc.conf files. 12505318f840SWarner Losh For example, change: 12515318f840SWarner Losh ifconfig_ath0="WPA DHCP" 12525318f840SWarner Losh to 12535318f840SWarner Losh wlans_ath0=wlan0 12545318f840SWarner Losh ifconfig_wlan0="WPA DHCP" 12550f95e625SWarner Losh see rc.conf(5) for more details. In addition, mergemaster of 12560f95e625SWarner Losh /etc/rc.d is highly recommended. Simultaneous update of userland 12570f95e625SWarner Losh and kernel wouldn't hurt either. 1258de570baaSSam Leffler 1259de570baaSSam Leffler As part of the multi-bss changes the wlan_scan_ap and wlan_scan_sta 1260de570baaSSam Leffler modules were merged into the base wlan module. All references 1261de570baaSSam Leffler to these modules (e.g. in kernel config files) must be removed. 1262de570baaSSam Leffler 1263ff0af72cSJung-uk Kim20080408: 1264ff0af72cSJung-uk Kim psm(4) has gained write(2) support in native operation level. 1265ff0af72cSJung-uk Kim Arbitrary commands can be written to /dev/psm%d and status can 1266ff0af72cSJung-uk Kim be read back from it. Therefore, an application is responsible 1267ff0af72cSJung-uk Kim for status validation and error recovery. It is a no-op in 1268ff0af72cSJung-uk Kim other operation levels. 1269ff0af72cSJung-uk Kim 1270e4c67b94SJeff Roberson20080312: 1271e4c67b94SJeff Roberson Support for KSE threading has been removed from the kernel. To 1272e4c67b94SJeff Roberson run legacy applications linked against KSE libmap.conf may 1273e4c67b94SJeff Roberson be used. The following libmap.conf may be used to ensure 1274e4c67b94SJeff Roberson compatibility with any prior release: 1275e4c67b94SJeff Roberson 1276e4c67b94SJeff Roberson libpthread.so.1 libthr.so.1 1277e4c67b94SJeff Roberson libpthread.so.2 libthr.so.2 1278e4c67b94SJeff Roberson libkse.so.3 libthr.so.3 1279e4c67b94SJeff Roberson 12808775db6fSMarcel Moolenaar20080301: 12818775db6fSMarcel Moolenaar The layout of struct vmspace has changed. This affects libkvm 12828775db6fSMarcel Moolenaar and any executables that link against libkvm and use the 12838775db6fSMarcel Moolenaar kvm_getprocs() function. In particular, but not exclusively, 12848775db6fSMarcel Moolenaar it affects ps(1), fstat(1), pkill(1), systat(1), top(1) and w(1). 12858775db6fSMarcel Moolenaar The effects are minimal, but it's advisable to upgrade world 12868775db6fSMarcel Moolenaar nonetheless. 12878775db6fSMarcel Moolenaar 1288df09ebc0SJack F Vogel20080229: 1289df09ebc0SJack F Vogel The latest em driver no longer has support in it for the 1290df09ebc0SJack F Vogel 82575 adapter, this is now moved to the igb driver. The 1291df09ebc0SJack F Vogel split was done to make new features that are incompatible 1292df09ebc0SJack F Vogel with older hardware easier to do. 1293df09ebc0SJack F Vogel 12941669d8afSAndrew Thompson20080220: 12951669d8afSAndrew Thompson The new geom_lvm(4) geom class has been renamed to geom_linux_lvm(4), 12961669d8afSAndrew Thompson likewise the kernel option is now GEOM_LINUX_LVM. 12971669d8afSAndrew Thompson 12982427fa19SKris Kennaway20080211: 12992427fa19SKris Kennaway The default NFS mount mode has changed from UDP to TCP for 13002427fa19SKris Kennaway increased reliability. If you rely on (insecurely) NFS 13012427fa19SKris Kennaway mounting across a firewall you may need to update your 13022427fa19SKris Kennaway firewall rules. 13032427fa19SKris Kennaway 13045e9f6b73SSam Leffler20080208: 13055e9f6b73SSam Leffler Belatedly note the addition of m_collapse for compacting 13065e9f6b73SSam Leffler mbuf chains. 13075e9f6b73SSam Leffler 130848aaad5fSYaroslav Tykhiy20080126: 130948aaad5fSYaroslav Tykhiy The fts(3) structures have been changed to use adequate 131048aaad5fSYaroslav Tykhiy integer types for their members and so to be able to cope 131148aaad5fSYaroslav Tykhiy with huge file trees. The old fts(3) ABI is preserved 131248aaad5fSYaroslav Tykhiy through symbol versioning in libc, so third-party binaries 131348aaad5fSYaroslav Tykhiy using fts(3) should still work, although they will not take 131448aaad5fSYaroslav Tykhiy advantage of the extended types. At the same time, some 131548aaad5fSYaroslav Tykhiy third-party software might fail to build after this change 131648aaad5fSYaroslav Tykhiy due to unportable assumptions made in its source code about 131748aaad5fSYaroslav Tykhiy fts(3) structure members. Such software should be fixed 131848aaad5fSYaroslav Tykhiy by its vendor or, in the worst case, in the ports tree. 131948aaad5fSYaroslav Tykhiy FreeBSD_version 800015 marks this change for the unlikely 132048aaad5fSYaroslav Tykhiy case that a portable fix is impossible. 132148aaad5fSYaroslav Tykhiy 132251dc1e12SRuslan Ermilov20080123: 13238015f45cSWarner Losh To upgrade to -current after this date, you must be running 132451dc1e12SRuslan Ermilov FreeBSD not older than 6.0-RELEASE. Upgrading to -current 13258015f45cSWarner Losh from 5.x now requires a stop over at RELENG_6 or RELENG_7 systems. 13268015f45cSWarner Losh 1327ab4a2c41SMatteo Riondato20071128: 1328ab4a2c41SMatteo Riondato The ADAPTIVE_GIANT kernel option has been retired because its 1329ab4a2c41SMatteo Riondato functionality is the default now. 1330ab4a2c41SMatteo Riondato 1331e393af84SMarius Strobl20071118: 1332e393af84SMarius Strobl The AT keyboard emulation of sunkbd(4) has been turned on 1333e393af84SMarius Strobl by default. In order to make the special symbols of the Sun 1334e393af84SMarius Strobl keyboards driven by sunkbd(4) work under X these now have 1335e393af84SMarius Strobl to be configured the same way as Sun USB keyboards driven 1336e393af84SMarius Strobl by ukbd(4) (which also does AT keyboard emulation), f.e.: 1337e393af84SMarius Strobl 1338e393af84SMarius Strobl Option "XkbLayout" "us" 1339e393af84SMarius Strobl Option "XkbRules" "xorg" 1340e393af84SMarius Strobl Option "XkbSymbols" "pc(pc105)+sun_vndr/usb(sun_usb)+us" 1341e393af84SMarius Strobl 134233d3fffaSMarius Strobl20071024: 134333d3fffaSMarius Strobl It has been decided that it is desirable to provide ABI 134433d3fffaSMarius Strobl backwards compatibility to the FreeBSD 4/5/6 versions of the 134533d3fffaSMarius Strobl PCIOCGETCONF, PCIOCREAD and PCIOCWRITE IOCTLs, which was 134633d3fffaSMarius Strobl broken with the introduction of PCI domain support (see the 134733d3fffaSMarius Strobl 20070930 entry). Unfortunately, this required the ABI of 134833d3fffaSMarius Strobl PCIOCGETCONF to be broken again in order to be able to 134933d3fffaSMarius Strobl provide backwards compatibility to the old version of that 135033d3fffaSMarius Strobl IOCTL. Thus consumers of PCIOCGETCONF have to be recompiled 135133d3fffaSMarius Strobl again. As for prominent ports this affects neither pciutils 135233d3fffaSMarius Strobl nor xorg-server this time, the hal port needs to be rebuilt 135333d3fffaSMarius Strobl however. 135433d3fffaSMarius Strobl 13553d461febSJulian Elischer20071020: 13563d461febSJulian Elischer The misnamed kthread_create() and friends have been renamed 13573d461febSJulian Elischer to kproc_create() etc. Many of the callers already 13583d461febSJulian Elischer used kproc_start().. 13593d461febSJulian Elischer I will return kthread_create() and friends in a while 13603d461febSJulian Elischer with implementations that actually create threads, not procs. 13613d461febSJulian Elischer Renaming corresponds with version 800002. 13623d461febSJulian Elischer 1363c15e0967SKen Smith20071010: 1364c15e0967SKen Smith RELENG_7 branched. 1365c15e0967SKen Smith 1366dc0dbf5cSWarner LoshCOMMON ITEMS: 1367dc0dbf5cSWarner Losh 1368a24eff53SWarner Losh General Notes 1369a24eff53SWarner Losh ------------- 1370456b5dd8SWarner Losh Avoid using make -j when upgrading. While generally safe, there are 1371456b5dd8SWarner Losh sometimes problems using -j to upgrade. If your upgrade fails with 13721733d35cSRuslan Ermilov -j, please try again without -j. From time to time in the past there 1373456b5dd8SWarner Losh have been problems using -j with buildworld and/or installworld. This 1374456b5dd8SWarner Losh is especially true when upgrading between "distant" versions (eg one 1375456b5dd8SWarner Losh that cross a major release boundary or several minor releases, or when 1376456b5dd8SWarner Losh several months have passed on the -current branch). 1377a24eff53SWarner Losh 13785780f3baSWarner Losh Sometimes, obscure build problems are the result of environment 13795780f3baSWarner Losh poisoning. This can happen because the make utility reads its 1380456b5dd8SWarner Losh environment when searching for values for global variables. To run 1381456b5dd8SWarner Losh your build attempts in an "environmental clean room", prefix all make 1382456b5dd8SWarner Losh commands with 'env -i '. See the env(1) manual page for more details. 13835780f3baSWarner Losh 1384456b5dd8SWarner Losh When upgrading from one major version to another it is generally best 1385456b5dd8SWarner Losh to upgrade to the latest code in the currently installed branch first, 1386456b5dd8SWarner Losh then do an upgrade to the new branch. This is the best-tested upgrade 1387456b5dd8SWarner Losh path, and has the highest probability of being successful. Please try 1388456b5dd8SWarner Losh this approach before reporting problems with a major version upgrade. 1389081ff8acSDoug Barton 13908fc25799SMartin Matuska ZFS notes 13918fc25799SMartin Matuska --------- 13928fc25799SMartin Matuska When upgrading the boot ZFS pool to a new version, always follow 13938fc25799SMartin Matuska these two steps: 13948fc25799SMartin Matuska 13958fc25799SMartin Matuska 1.) recompile and reinstall the ZFS boot loader and boot block 13968fc25799SMartin Matuska (this is part of "make buildworld" and "make installworld") 13978fc25799SMartin Matuska 13988fc25799SMartin Matuska 2.) update the ZFS boot block on your boot drive 13998fc25799SMartin Matuska 14008fc25799SMartin Matuska The following example updates the ZFS boot block on the first 14018fc25799SMartin Matuska partition (freebsd-boot) of a GPT partitioned drive ad0: 14028fc25799SMartin Matuska "gpart bootcode -p /boot/gptzfsboot -i 1 ad0" 14038fc25799SMartin Matuska 14048fc25799SMartin Matuska Non-boot pools do not need these updates. 14058fc25799SMartin Matuska 1406dc0dbf5cSWarner Losh To build a kernel 1407dc0dbf5cSWarner Losh ----------------- 1408ba01eb20SWarner Losh If you are updating from a prior version of FreeBSD (even one just 14091cf0ef11SDavid E.

Make sure that before you update 15011dece4a9SWarner Losh your sources that you have read and understood all the recent 15021dece4a9SWarner Losh messages there. If in doubt, please track -stable which has 15031dece4a9SWarner Losh much fewer pitfalls. 15041dece4a9SWarner Losh 1505134d2e86SWarner Losh [1] If you have third party modules, such as vmware, you 1506134d2e86SWarner Losh should disable them at this point so they don't crash your 1507134d2e86SWarner Losh system on reboot. 1508134d2e86SWarner Losh 1509ee6e1fc3SWarner Losh [3] From the bootblocks, boot -s, and then do 1510ee6e1fc3SWarner Losh fsck -p 1511ee6e1fc3SWarner Losh mount -u / 1512ee6e1fc3SWarner Losh mount -a 15136586253aSWarner Losh cd src 151447d0d01fSWarner Losh adjkerntz -i # if CMOS is wall time 1515f6a0ef01SWarner Losh Also, when doing a major release upgrade, it is required that 1516f6a0ef01SWarner Losh you boot into single user mode to do the installworld. 1517ee6e1fc3SWarner Losh 1518a6cd4f9dSWarner Losh [4] Note: This step is non-optional. Failure to do this step 1519a6cd4f9dSWarner Losh can result in a significant reduction in the functionality of the 1520a6cd4f9dSWarner Losh system. Attempting to do it by hand is not recommended and those 1521a6cd4f9dSWarner Losh that pursue this avenue should read this file carefully, as well 1522a6cd4f9dSWarner Losh as the archives of freebsd-current and freebsd-hackers mailing lists 152350e8eca6SDoug Barton for potential gotchas. The -U option is also useful to consider. 152450e8eca6SDoug Barton See mergemaster(8) for more information. 1525a6cd4f9dSWarner Losh 1526835284beSWarner Losh [5] Usually this step is a noop. However, from time to time 1527835284beSWarner Losh you may need to do this if you get unknown user in the following 1528835284beSWarner Losh step. It never hurts to do it all the time. You may need to 1529835284beSWarner Losh install a new mergemaster (cd src/usr.sbin/mergemaster && make 1530835284beSWarner Losh install) after the buildworld before this step if you last updated 1531835284beSWarner Losh from current before 20020224 or from -stable before 20020408. 1532835284beSWarner Losh 153394877c06SAlexander Leidinger [6] This only deletes old files and directories. Old libraries 153494877c06SAlexander Leidinger can be deleted by "make delete-old-libs", but you have to make 153594877c06SAlexander Leidinger sure that no program is using those libraries anymore. 153694877c06SAlexander Leidinger 1537456b5dd8SWarner Losh [8] In order to have a kernel that can run the 4.x binaries needed to 1538456b5dd8SWarner Losh do an installworld, you must include the COMPAT_FREEBSD4 option in 1539456b5dd8SWarner Losh your kernel. Failure to do so may leave you with a system that is 1540456b5dd8SWarner Losh hard to boot to recover. A similar kernel option COMPAT_FREEBSD5 is 1541456b5dd8SWarner Losh required to run the 5.x binaries on more recent kernels. And so on 1542456b5dd8SWarner Losh for COMPAT_FREEBSD6 and COMPAT_FREEBSD7. 1543c74fe6afSWarner Losh 1544e5dc5f61SWarner Losh Make sure that you merge any new devices from GENERIC since the 1545e5dc5f61SWarner Losh last time you updated your kernel config file. 1546e5dc5f61SWarner Losh 154721c075eaSWarner Losh [9] When checking out sources, you must include the -P flag to have 1548e5dc5f61SWarner Losh cvs prune empty directories. 1549e5dc5f61SWarner Losh 1550e5dc5f61SWarner Losh If CPUTYPE is defined in your /etc/make.conf, make sure to use the 1551e5dc5f61SWarner Losh "?=" instead of the "=" assignment operator, so that buildworld can 1552e5dc5f61SWarner Losh override the CPUTYPE if it needs to. 1553e5dc5f61SWarner Losh 1554e5dc5f61SWarner Losh MAKEOBJDIRPREFIX must be defined in an environment variable, and 1555e5dc5f61SWarner Losh not on the command line, or in /etc/make.conf. buildworld will 1556e5dc5f61SWarner Losh warn if it is improperly defined. 1557dc0dbf5cSWarner LoshFORMAT: 1558dc0dbf5cSWarner Losh 1559f699bbbbSMark OvensThis file contains a list, in reverse chronological order, of major 1560630f2154SGlen Barberbreakages in tracking -current.
