Recent changes: ^^^^^^^^^^^^^^^ -20041001: - The ipfilter kernel sources moved from sys/netinet to - dist/sys/ipf/netinet. Due to the move some Makefile - dependencies are now dangling requiring a make cleandir - before they work again (kdump, ktruss, rescue, ipf are - amongst the victims). - -20040715: - The rc.d/sendmail script now uses a heuristic to determine - if sendmail should be started at boot time. It checks the - contents of /etc/mailer.conf, /etc/mail/submit.cf, and the - owner and mode of the sendmail binary to see if any changes - to the mail infrastructure have been made. If no changes - are detected, it will start an SMTP listener. - - Setting sendmail=NO in /etc/rc.conf will override this. - - If you are only using sendmail by default and only for - local delivery, it is important that you also update your - sendmail.cf so that the SMTP listener only listens on the - loopback interface. - -20040715: - The method by which athhal-elf.o gets pulled into i386 - kernel builds has been changed again. The latest version - of bsd.files.mk is no longer required. - -20040621: - Due to the recent rototill of tools/compat it's crucial one starts - from a clean objdir under tools/*. - - This is mostly due to generated files (yacc and lex sources) needing - to be generated with new rules from bsd.hostprog.mk. - - The safest course is to rm -rf all objects under tools before building. - -20040516: - The end-user modifiable X11 configuration has been moved - from /usr/X11R6/lib/X11/ to /etc/X11/. - Ensure that src and xsrc is up to date, and run - "make cleandir" in src/x11 before your next build. - - postinstall currently doesn't migrate the files from - /usr/X11R6/lib/X11/* to /etc/X11/* although it does - detect that this needs to occur, so you'll have to - manually move these files yourself. - -20040426: - Support for the original dynamic sysctl node structure has - been removed in favor of the newer layout. This affects - consumers of the create and delete interface, as well as - the dynamic discovery mechanism. This is believed only to - be the sysctl(8) binary itself, at this point in time, so - the only effect of this should be that a sysctl binary - built from sources dated between 2003/12/04 and 2004/03/24 - will not work on a kernel built from sources dated after - 2004/04/25. If you need a new sysctl binary but build.sh - does not work, make sure that your revision of - src/sys/sys/sysctl.h is 1.112 (or later), and then the - do the following: - - cd /usr/src (or wherever your source tree is) - make USETOOLS=no includes - cd lib/libc - make USETOOLS=no dependall install - cd ../../sbin/sysctl - make USETOOLS=no dependall install - - If you are using older sysctl binary, GNU autoconf would fail to - identify your machine architecture, and tries to build binary for - "unknown-unknown-netbsd20F" or something like that. if that happens, - make sure to follow the above steps. - -20040425: - The ffs superblock issues listed below under 20040109 and 20030402 - are now automatically addressed by the /etc/rc.d/fixsb script or by - sysinst when it checks a a filesystem. The manual fsck_ffs -b16 -c4 - invocation mentioned below will continue to work and is now - automated by those scripts. Note that under certain circumstances, - affected filesystems upgraded to a -current kernel first before - upgrading their userland with the fixsb and fsck_ffs fixes may - encounter a 'freeing free inode' panic when writing to the affected - filesystem, so it is a good idea to repair the filesystem as soon as - possible. For more details on the fixsb script, see pr install/25138. - -20040418: - statfs(2) and friends have been replaced with statvfs(2). Before - installing a newly build userland make sure that you are running - a newly built kernel with COMPAT_20 set. In addition your libc - build might not work (undefined SYS_statfs symbol) because make - clean does not know how to remove files it does not know about - anymore. Manually remove all generated .S sources and objects - from the libc build directory. - -20040326: - The method by which athhal-elf.o gets pulled into i386 kernel builds - has been changed. The file is now stored as a uuencoded file in CVS - and the generated Makefile will use the new .uue rules from bsd.file.mk - to build it. - - This means you must have the latest bsd.files.mk installed when - building a kernel without USETOOLS=yes. - -20040318: - A bug in the cgd(4) blowfish code was corrected, without - provision of backwards compatibility, after several public - notices over several months. Users of cgd with blowfish cipher - ONLY must dump their data before updating their kernels, and - recreate cgd's and restore data using the new kernel. See - (recent message to current-users, URL when mail-index has updated) - -20040313: - On acorn32, the opms and qms drivers have been withdrawn, and - the old wsqms driver is now called qms. Kernel config files - will need updating. See the ones in sys/arch/acorn32/conf - for examples. - -20040125: - On acorn32, the beep and sysbeep devices are no longer - needed, and will need to be deleted from kernel configuration - files. - -20040109: - Compatibility for old ffs superblock layouts has been - added, and the restrictive fsck checks have been reenabled - when using those layouts. If you have been using -current - since 20030402, you may find that fsck again signals fatal - superblock mismatches. To repair, make sure you have - an updated fsck_ffs and then you can use fsck_ffs -b 16 -c 4 - to complete the filesystem upgrade. A message has - been added to the kernel which should detect this problem. - See the following discussion for more information: - http://mail-index.NetBSD.org/current-users/2004/01/11/0022.html - -20031203: - New binutils builds may fail due to old dependencies. - It's necessary to "make cleandir" to ensure that - the dependencies will be rebuilt correctly. - -20031111: - A newer mkdep is needed. Error noting that is - cc: Ambiguous abbreviation -- - -20031008: - /usr/include/sys/disklabel_mbr.h was removed. - It's necessary to "make cleandir" to ensure that - the dependencies will be rebuilt correctly. - -20031007: - A sign exension bug was fixed which set all the high bits - of our newly expanded ffs fs_flags. This should only - affect users who installed or upgraded in September of 2003. - A small utility program was posted to tech-kern which - should fix this problem, and a warning message was added - to the kernel which should discover and warn about it. See - http://mail-index.NetBSD.org/tech-kern/2003/10/07/0005.html - -20030906: - With the addition of siginfo support the old signal trampoline - code has been deprecated to COMPAT_16. Make sure that your running - kernel has COMPAT_16 enabled before building userland. - -20030801: - With the new openssl, there is some header and library shuffling. - rm -f /usr/include/des.h /usr/include/kerberosIV/* /lib/libdes* \ - /usr/lib/libdes* before building. - -20030703: - Texinfo was updated to 4.6. To avoid failures when trying to - build the included texinfo files, do: - - cd src/gnu/usr.bin/texinfo - make MKINFO=no dependall install - -20030630: - Groff was updated to 1.19; it's probably necessary to do - cd share/mk && make install - cd src/gnu/usr.bin/groff - make MKMAN=no dependall install - (untested). - -20030516: - Due to bugs in the export handling code, invalid export lines - were accepted before and caused the kernel to panic when - mountd got restarted because it freed memory that had already - been freed. This has been fixed and the kernel checks - export addresses very strictly. If you upgrade your kernel, - make sure you also upgrade mountd, because if your export - file contains lines with an old inet4 address syntax (i.e. - a.b.c or a.b or a), they will get rejected by the new kernel. - -20030402: - The superblock layout for FFS was changed. If you have 1.6 - fsck binaries, they will signal a fatal superblock mismatch - with the first alternate, because they compare too many - fields (even ones that aren't useful). If possible, upgrade - your fsck_ffs binary before using a new kernel. - None of this signals actual filesystem damage. - -20030324: - sendmail version 8.12.8 was imported. Since sendmail is - now setgid to the smmsp group, and runs in "collection" - mode for most common activities, there is a new config - file called submit.cf that needs to live in /etc/mail. - The generic submit.cf sample in /usr/share/sendmail/cf - is named netbsd-msp.cf. Upgrading your regular sendmail - configuration file is also strongly advised. - - See the section named "MESSAGE SUBMISSION PROGRAM" in - the updated /usr/share/sendmail/README file for more - information. - -20030117: - Texinfo was updated to 4.3. To avoid failures when trying to - build the included texinfo files, do: - - cd src/gnu/usr.bin/texinfo - make MKINFO=no dependall install - -20021223: - The METALOG format changed slightly, to remove the leading - "${DESTDIR}" from path names. - This only affects people building with UNPRIVED. - For complete safety, remove the DESTDIR entirely and - update tools/mtree, before running make build. - -20021219: - CVS repository layout was changed. See the following for details - if you are using (anonymous) cvs to update your tree. - - http://mail-index.NetBSD.org/netbsd-announce/2002/12/19/0000.html - -20021219: - install(1) had a '-N dbdir' option added, to specify an - alternate location to look up users & groups (instead - of the host system passwd(5) and group(5) databases). - - The build system was modified to take advantage of - this option (using ${NETBSDSRCDIR}/etc), so if you - use USETOOLS==no, you may have to rebuild and - reinstall usr.bin/xinstall first. - -20021130: - fparseln(3) moved from libutil to libc. - If building to DESTDIR=/, reinstall the includes - and rebuild libc: - make includes - make do-lib-libc - If using build.sh, "cd tools/compat && make clean" - before rebuilding the tools. - -20021126: - The mk.conf(5) variable SYS_INCLUDE has been deprecated, - including the optional "SYS_INCLUDE=symlinks" support. - All header files, including are copied into - /usr/include. - -20021121: - The C run-time support files crtbegin.o and crtend.o - (and their companions crtbeginS.o and crtendS.o) were - split up, with new crti.o and crtn.o files resulting. - This means that libtool needs to be rebuilt once the - new libraries are installed. The process of rebuilding - libtool will cause it to automatically notice the new - required files, but it *must* be rebuilt in order to - do this. - - An out-of-date libtool will result in shared libraries - which lack _init() and _fini() routines, which means that - their global contructors/destructors will not be invoked. - -20021121: - A bug related to how ARM ELF objects were tagged has been - corrected. - - NetBSD ARM ELF uses the soft-VFP floating point model by - default. However, the assembler lacked support for marking - objects as using the VFP floating point format, and the - compiler was not properly passing the flag indicating "soft-VFP" - to the assembler. - - Unfortunately, this means that the linker will now consider - old (i.e. not marked "softvfp") NetBSD ARM ELF objects to be - incompatible with new (properly marked) objects. - - The problem will only manifest itself if you attempt to compile - a new program using the fixed toolchain, and link that program - against old libraries which do not have the proper "softvfp" - markings. ALL OF YOUR EXISTING BINARIES AND SHARED LIBRARIES - WILL CONTINUE TO WORK PROPERLY. - - The only work-around for the problem is to recompile all of - the libraries on the system. The easiest way to do this for - system libraries is to install a binary snapshot; they are - generally available on releng.NetBSD.org. Any packages you - have installed which supply libraries will have to be recompiled - if you wish to link new programs against those libraries. - - If you have questions about this matter, please contact - port-arm@NetBSD.org. - -20021011: - Systrace has been improved to support privilege elevation. - Updating the kernel requires the userland part of systrace - to be rebuilt. - -20021010: - The config(8) grammar was changed to allow options to register - dependencies on attributes, as well as other options. Users - must update and reinstall usr.sbin/config before building a new - kernel. - -20021009: - A new attribute dependency syntax was introduced to config(8), - which is now used by the SCSI configuration description. Users - must update and reinstall usr.sbin/config before building a new - kernel. - -20021003: - Several changes have been made to the autoconfiguration - framework. Users must update and reinstall usr.sbin/config - before building a new kernel. - -20021001: - The i386mp branch has been merged. To compile a kernel, users - will need to add the option 'cpu* at mainbus?' to their configuration - file. Multiprocessor kernels will need - ioapic* at mainbus? apid ? - options MULTIPROCESSOR - options COM_MPLOCK - -20020922: - MKDYNAMICROOT=yes enabled by default, which means that - certain shared libraries are installed into /lib, the shared - linker is installed into /libexec, and all programs in /bin - and /sbin are dynamically linked. - If you do not use "make build", you should ensure that - you have the libraries and shared linker in the new locations, - with: - make do-lib-csu do-lib-libc do-lib do-gnu-lib do-ld.elf_so - -20020917: - USE_NEW_TOOLCHAIN has been replaced with: - - TOOLCHAIN_MISSING -- set to "yes" on platforms for which - there is no working in-tree toolchain (hppa, ns32k, sh5, - x86_64). - - EXTERNAL_TOOLCHAIN -- if defined by the user, points to the - root of an external toolchain (e.g. /usr/local/gnu). This - enables the cross-build framework even for TOOLCHAIN_MISSING - platforms. - -20020906: - gehenna-devsw has been merged into the trunk. Need to update and - reinstall usr.sbin/config before building the kernel. - -20020822: - Crunched rescue tools (contents of /bin and /sbin, plus others) - are now provided in /rescue. - - To ensure that these are built statically linked (no matter - what the setting of LDSTATIC is), use a crunchgen(1) built - from sources newer than 20020820 (see the next entry). - -20020820: - crunchgen(1) changed to ensure that the generated program - is statically linked. - - Solution: update and reinstall usr.bin/crunch - -20020605: - smmsp user/group has been added for sendmail. - - Add the following into /etc/group: - - smmsp:*:17: - - and the following to /etc/master.passwd (via vipw): - - smmsp:*:17:17::0:0:Sendmail Message Submission Program:/nonexistent:/sbin/nologin - -20020515: - sshd user/group has been added. Need to hand add this in, or sshd - will not let you log in (with default, or UsePrivlegeSeparation=yes) - - Add the following into /etc/group: - - sshd:*:16: - - and the following to /etc/master.passwd (via vipw): - - sshd:*:16:16::0:0:& pseudo-user:/var/chroot/sshd:/sbin/nologin - - Also /var/chroot/sshd directory needs to be present (digged as part of - the build process). - -20020426: - NBUILDJOBS obsoleted in favor of just using -j. - -20020426: - etc/postinstall added, which performs various checks for - configuration file updates and changes, and can fix most of - the problems identified. - This should make it much easier to upgrade a system's - configuration from earlier systems (as far back as NetBSD 1.5). - -20020320: - needs a new install(1) for its "-a cmd" support. - Build and install at usr.bin/xinstall before the build. - -20020319: - Raw IPv6 socket now makes strict checking for sa_family and sa_len - on send(2) operation. Be sure to have sbin/rtsol and usr.sbin/rtsold - newer than November 2001 when you upgrade the kernel. - -20020311: - ssh configuration files were moved from /etc to /etc/ssh. Beware - if you restart your machine from remote. Note that sshd.conf needs - to be changed (due to the use of "/etc" inside). - -20020223: - Users of the VAX port will need to rebuild and install gas - so it deal with the now present register prefix used in all - the VAX assembly files. - -20020118: - ntpd user/group has been added. Need to hand add this in or builds - will break as mtree aborts early. - - Add the following into /etc/group: - - ntpd:*:15: - - and the following to /etc/master.passwd (via vipw): - - ntpd:*:15:15::0:0:Ntpd pseudo-user:/var/chroot/ntpd:/sbin/nologin - -20011207: - If you're attempting to build a snapshot on sparc64 and are getting - reloc errors from the toolchain groff binary this means your native - toolchain has some broken C++ bits. - - To fix: - - Build a new toolchain (i.e. build.sh -t) - Use the new toolchain to build and install natively (i.e. /usr/lib) - - gnu/lib/libgcc - gnu/lib/libstdc++ - - After this a snapshot will be able to be built. - -20011201: - In order for a sparc64 build to work you must have a working awk. If - you've built and installed a system with the new toolchain up to this - point you do not have a working awk as its ability to do floating - point is broken. - - To build: - - remake and install gnu/lib/libgcc - remake and install gnu/usr.bin/gawk into /usr/bin (make sure it links - against the new libgcc.a) - -20011128: - Kernel config information was changed to use defflag in - the various "files" files. Bug fixes to config(8) are - required in order for this to work properly. Make sure - to build and install in usr.sbin/config before attempting - to build a new kernel. - -20011030: - libc/locale/wcstod.c now needs new lint(1). Update lint(1) - before building libc. - -20011029: - The new document BUILDING.mdoc (view with nroff | more, or - see pre-generated .txt and .html versions) describes the build - procedure in great detail. BUILDING, and the USE_NEW_TOOLCHAIN - build process, are intended in the long run to replace this - manual update log. - - Users building a USE_NEW_TOOLCHAIN system should read the - BUILDING document for caveats. Generally, BUILDING supersedes - UPDATING for these systems, as tool updating is taken care of - by the new build system. - -20011028: - src/etc/Makefile now needs install to be able to handle - symlinks that point to nowhere. A bug in install that - prevented this was corrected. - - Solution: update and reinstall usr.bin/xinstall - Better Solution: Use the new toolchain and it will just work - for you. - -20011006: - /etc/mtree/NetBSD.dist has been updated to take advantage of - absolute path support added to mtree(8). Older mtree(8)s don't - understand the format. - - Solution: update and reinstall usr.sbin/mtree - -20011004: - Crunchgen has been updated to work via reach-over makefiles. Updating - is suggested before running a snapshot build - -20010915: - The new "ubcperf" code committed by Chuck Silvers removed - a header file, uvm/uvm_vnode.h. There may be stale .depend - files that still reference this file. - - Solution: "make cleandir && make dependall" in affected - directories. - -20010803: - grep.info is now built from grep.texi using makeinfo. Since it - requires makeinfo v4.0, you need to install new texinfo before - building gnu/usr.bin/grep. To install new texinfo, please follow - the instruction described in 20010726 entry. - -20010803: - (i386 only): i386 kernel now uses new instructions like - `fxsave' which old gas doesn't understand. To build the - kernel successfully, you need to build and install a new toolchain, - (i.e., build.sh -t) or (temporarily) comment out "options I686_CPU" - from your kernel configuration until you rebuild your userland. - See 20011029 above and BUILDING file in this directory for more information. - [updated 20020630 since i386 gas moved when USE_NEW_TOOLCHAIN enabled] - -20010731: - Bootloader update on ELF platforms. DDB in kernels from before - this will be unable to read symbol tables provided by newer - bootloaders. - -20010726: - Texinfo was updated to 4.0. To avoid failures when trying to - build the included texinfo files, do: - - cd src/gnu/usr.bin/texinfo - make MKINFO=no dependall install - -20010718: - Enabled correct .init/.fini processing in crt0. The way this - was done was to change a -I directive to cc(1), which means - make(1) will have a stale dependency (it will be checking the - timestamp on the wrong "dot_init.h"). - - The symptom you will see is that new programs die with SIGSEGV - if you have a stale dependency. - - Solution: "make cleandir" in both lib/csu and libexec/ld.elf_so - before starting your build. - -20010628: - A construct was added to uvm_page.h that uncovered a bug - in lint(1). If you get a warning/error about a non-portable - bitfield, update your lint(1) before proceeding. - -20010226: - Added named user/group to system. Need to hand add this in or builds - will break as mtree aborts early. - - To work around add by hand: - - named:*:14: - - to /etc/group and add: - - named:*:14:14::0:0:Named pseudo-user:/var/named:/sbin/nologin - - to master.passwd (use vipw for instance if doing by hand). - - Now a make build should progress. - -20010219: - get/setprogname() added. Any hostprogs that may use this will need - to be bootstrapped manually until the host system is current. - - Known problems: sys/arch/macppc/stand/fixcoff - usr.sbin/config (adding -DMAKE_BOOTSTRAP to - CFLAGS and rebuilding should work) - usr.sbin/mdsetimage - Build a static copy if - building a snapshot before fully bootstrapped. - -20010204: - prepare the code to compile with stricter gcc flags. in - particular start eliminating redundant declarations. Yacc - needs to be installed before make build. - -20010114: - introduce .if commands(target) in make(1). You need to - bring everything up-to-date first, then without installing - anything make and install in usr.bin/make, then proceed - with make build. - -20010101: - bsd.subdir.mk committed 20001230 had a bug which caused - afterinstall targets to run too soon; update again. - -20001230: - New share/mk files needed to support .WAIT in SUBDIR variables. - If you get make errors, - (cd share/mk; make install) - Also, PRINTOBJDIR has changed and is now used more heavily. - -20001019: - The `ca' device driver has been replaced by `ld'; although the - major and minor numbers haven't changed, you should update your /dev +20130605: + Previous freetype installations eroneously installed private + header files. If you are building against a non-empty $DESTDIR, + please remove ${DESTDIR}//usr/X11R7/include/freetype2/freetype/. + +20130531: + The xdm update may cause build failure due to xdm.man being + in the obj tree. Make sure to ensure any like this: + nbmake: nbmake: don't know how to make xdm.man. Stop + is fixed by deleting the xdm.man in the obj tree. + +20130530: + Updates of many xsrc packages will leave old .pc files around. + Best to clean out the xsrc objdir entirely before rebuilds. + +20130301: + The removal of netiso requires manual removal of /usr/include/netiso + prior to the build and make cleandir in /usr/src/usr.bin/{ktruss,kdump} + +20120726: + The update of OpenSSL requires cleaning both the OpenSSL build + directory and DESTDIR. *Even non-update builds require cleaning + DESTDIR.* Builds done without taking these steps may fail, or in + some cases may succeed and install broken OpenSSL libraries that + cause third-party software to link incorrectly and/or crash. + +20120507: + The database schema for makemandb was changed. You will + need to update the database using 'makemandb -f' or wait + for the next weekly run to fix it. + +20120319: + sys/conf/Makefile.kern.inc has been modified to adjust the + size of db_symtab automatically.

If + you don't want this behavior, add AUTO_SYMTAB_SPACE=no to your + mk.conf. + +20120216: + Default for MKCATPAGES changed to NO. Update builds will fail + unless DESTDIR is cleaned manually. If you built between 20120207 + and 20120216, daily and weekly could have created an unreadable + /var/db/man.db index for apropos. Running makemandb -f or + the next run of weekly will fix it. + +20111227: + If you built between 20111225 and 20111227 you need to remove + /usr/lib/libpam.so.4* and /usr/lib/security/*.so.4, since the + bump has been reverted. + +20111125: + The "rnd" pseudodevice has been added to sys/conf/std, which + means it should no longer be explicitly listed in kernel + configuration files. The line "pseudo-device rnd" should be + removed from any custom kernel config files users may have. + +20111119: + A problem with the datastructures used by the rndctl(8) + utility (pointers in datastructures in an array, making 32->64 + bit compatibility very painful) has been fixed in a + non-backwards-compatible way.

So ensure that all consumers of these functions (currently: + quota2 code and its tests) are updated together with the new lib. + +20110817: + sparc has been changed to use GCC 4.5.3, so any objdir or + DESTDIR for them should be deleted before updating. + +20110806: + i386 and amd64 have been changed to use GCC 4.5.3, so any + objdir or DESTDIR for them should be deleted before updating. + +20110805: + The update to GCC 4.5.3 requires a non-trivial portion of + the tree to be cleaned. Best to delete both objdir and + DESTDIR before running this update. So far, only the + sparc64, mips and powerpc platforms have changed. + +20110803: + The layout of external/public-domain/xz has changed. To do an + update build you will have to remove the contents of the OBJDIR + for external/public-domain/xz/bin by hand as the xz entry there + is now a directory. + +20110410: + The configuration of src/tools/gcc has changed. To do an + update build you have to clean both tools/binutils and + tools/gcc by hand. + +20110328: + Building the Xorg binary was moved into a subdirectory to fix + ordering issues with "make all".

By using MKCRYPTO_{RC5,IDEA}, you can build - additional library libcrypto_{idea,rc5}. - +20110121: + Assembler files no longer use -traditional-cpp. This can break + the build of individual parts of the tree. This is handled + correctly by build.sh. Manual builds have to update /usr/share/mk + and re-run config(1) for any kernel configurations as needed. + +20101217: + The tcpdump(8) program was changed to drop privileges and chroot(2) + by default. It may be necessary to manually update passwd(5) and + group(5) in order to make the program work with existing setups. + +20101125: + The latest changes to setenv(3) dissallow setting environment + variables with names that contain '='.

Delete your entire DESTDIR and OBJDIR if you + have any build problems with xsrc, or problems with mismatched + versions between xorg-server and drivers. + +20100604: + The update of ATF to 0.9 causes old tests written in shell to fail + unless they are rebuilt. If you are building with MKUPDATE=yes, + you need to clean the src/external/bsd/atf/tests/ and the src/tests/ + trees by hand. + +20100522: + Recent Xorg updates in xsrc/external/mit/ will cause various build + problems. Delete your entire DESTDIR and OBJDIR if you have any + build problems with xsrc. + +20100522: + private section of was splitted, and now mklocale(1) + include ctype_local.h, so you have to make cleandir in tools/mklocale. + +20100520: + The location of the xkb compiled descriptions has changed. Please + remove usr/X11R7/lib/X11/xkb/compiled from your $DESTDIR. + +20100222: + The shared objects file extension has been changed from .so to + .pico, in order to avoid conflicts with shared libraries names + libXX.so. All now stale regular .so files can be removed from + your object directories. + +20100204: + The termcap database has been removed from the sources, + but has not been marked obsolete so it is not removed + from the system when upgrading. + As such, you will need to remove them from your object + and destination directories. + +20091101: + After updating, it may be necessary to make the 'cleandir' + target in src/tools/yacc/ and in src/usr.bin/yacc/ before a + 'build.sh -u tools' or 'build.sh -u distribution'. Ditto + src/tools/lex/ and src/usr.bin/lex/. + +20091001: + On amd64 you must rebuild tools (to get the new binutils) + before building a kernel, or the build fails on cpufunc.S. + +20091001: + An error will create a ./usr/X11R7/lib/X11/xkb/compiled/xkb + symlink, failing the build. Delete the link, and the subdir + it is in, and retry your build. + +20090718: + libc build changed so that strchr() provides the extra entry + point for index(). Update build of libc.a (and libc_pic.a) + may fail because the archive contains the unwanted index.o. + (Similarly for strrchr() and rindex().) + +20090709: + Native Xorg was upgraded again. Builds will probably fail again + without a clean objdir, at least for src/external/mit/xorg. + +20090616: + Native Xorg was upgraded. Builds will need a clean objdir for + src/external/mit/xorg. Upgrading a system from sets will not + work properly yet as the /usr/X11R7/lib/X11/xkb/symbols/pc + subdirectory has been changed into a file, and this needs to + be manually "rm -r"'ed before installing xbase.tgz. + +20090501: + Several new functions were added to string.h/libc, and this + can cause autoconf problems during the tool build for people + who fail to clean out their tools objects properly. If you + note messages about stpcpy, stpncpy or strnlen accompanying a + failure during the tool build, clean out all your tools + objects and start again. + +20090325: + The i386 port was switched to i486 default toolchain. This requires + cleaning your src/tools directory and $TOOLDIR and rebuilding them. + +20090126: + The __posix_fadvise50 system call changed assembly stub type. You + need to 'rm -f __posix_fadvise50.*' in the libc build directory + to avoid using the old assembly stub. + +20090202: + pkg_install now depends on the pkgdb cache for automatic conflict + detection. It is recommented to rebuild the cache with + ``pkg_admin rebuild''. + +20090110: + time_t and dev_t have been bumped to 64 bit quantities. To upgrade: + 1. Make sure your kernel has COMPAT_50 in it. Build and install. + This is needed even in the MODULAR kernel because there is + conditionally compiled code in rtsock.c. + 2. make sure build.sh completes and the binaries in a chroot work + before installing. + 3. If you don't use build.sh and you build directly to root, and + your build breaks in the middle, don't despair. Make sure headers + are installed properly, and start building libraries first libc + and libutil, install them and then continue building all the + libraries in src/lib and src/gnu/lib and install them. Once + the new libraries are installed, you can restart the build. + 4. If you compile packages and you notice link time warnings, + rebuild the required packages to update their shared libraries. + Any package you rebuild will require rebuilding all the packages + that depend on it. + 5. Next time you run pwd_mkdb with the new binary, the file + will be upgraded and it will not be backwards compatible. + 6. The utmpx/wtmpx files (/var/run/utmpx and /var/log/wtmpx, see + lastlogx(5)) have been versioned, and there is a heuristic + for utmp. You are better off removing the old files after + upgrading. The automated clearing of /var/run during + boot, and the automated rotating of files in /var/log by + newsyslog(8), may mean that you do not have to remove the + files manually. + 7. The optional accounting file (/var/account/acct, see + accton(8)) has not been versioned, and will need to be + removed. The automatic rotation of the accounting file by + /etc/daily limits the bad consequences of failure to remove + the file. + 8. Application software that writes time_t to binary files on + disk will break or need attention. Most notably: if you are + using PostgreSQL < 8.4, you need to dump your databases, + rebuild PostgreSQL with the new time_t, then restore. + +20081219: + config(1) has been updated, and one of the files it creates - + swapnetbsd.o - has changed format. You need to rebuild config + (done automatically by build.sh) and then you need to rerun + config on all kernel configuration files before rebuilding those + kernels. + +20081205: + If you build with MKX11=no, you should remove /etc/rc.d/xdm and + /etc/rc.d/xfs from DESTDIR because those files were moved to the xetc + set and will appear as extra files for MKX11=no update builds. + +20081122: + On i386, various kernel options(4) in GENERIC including + file systems have been disabled and moved into kernel modules. + Before trying a new GENERIC kernel, you have to prepare the + following files as well as a new GENERIC kernel: + + - build and install kernel modules from src/sys/modules + + - install the latest bootloader, which will load a module + for the file system from which the kernel is loaded automatically + + If you have to load your kernel from a file system which is not of + the same type as the root file system, you have to load the necessary + file system module manually on the boot prompt or in the boot.cfg file. + +20080827: + If you built and installed a libc from sources between + 2008/08/20 and 2008/08/26 you got a broken strtouq(3) + which results in false errors reported by lint(1). + Since this breaks the libc build itself, manual help is + needed -- lint must be disabled temporarily, e.g.: + $ (cd lib/libc && make MKLINT=no dependall install) + +20080813: + MKDEBUG build was broken because the .depend files did not know + about .go files. You need to remove all .depend files and rebuild. + +20080802: + A regression in binary compatibility for pthread_mutex_t has + been fixed. Unfortunately, the price is breaking compatibility + for -current. + + Threaded programs (using libpthread) and C++ programs (using + libstdc++) compiled after 20070907 and before 20080802 need to + be recompiled. + + One way to find affected pkgsrc packages: + + $ grep REQUIRES=/usr/lib/libpthread /var/db/pkg/*/+BUILD_INFO + $ grep REQUIRES=/usr/lib/libstdc++ /var/db/pkg/*/+BUILD_INFO + +20080731: + WAPBL (metadata journaling support) has been added, but at this + time isn't backwards compatible with pre-WAPBL aware kernels + and userland (fsck_ffs in particular). Please make sure you + don't use a journaled filesystem with an older kernel/userland, + especially an uncleanly mounted journaled filesystem. WAPBL + also requires the super block to be in the UFS2 format. You + can use fsck_ffs -c 4 to update the superblock format. + +20080721: + Assembler warnings are now fatal if $WARNS>0 and $NOGCCERROR + isn't defined. + +20080531: + The ioctl number of DRVSUSPENDDEV command on /dev/drvctl changed + from 125 (conflicted with DRVCTLCOMMAND) to 129. The drvctl(8) + utility needs to be rebuilt and reinstalled as older binaries + won't work correctly. The following sequence of commands: + + $ (cd sys/sys/ && nbmake-$arch includes) + $ (cd sbin/drvctl/ && nbmake-$arch clean) + $ (cd sbin/drvctl/ && nbmake-$arch all) + + leaves new drvctl utility in sbin/drvctl build directory. + +20080503: + The variable MKPRIVATELIB was renamed to LIBISPRIVATE. + +20080521: + For a while, unprivileged UPDATE builds would fail to + succeed at the checkflist stage, complaining that + ${DESTDIR}/stand// did not exist. A fix for this + problem was committed to share/mk/bsd.kmodule.mk, revision 1.9. + If you already hit this problem, update the .mk file, + remove ${DESTDIR}/stand/, and re-run the build. + +20080303: + Linker warnings are now fatal if $WARNS>0. + +20080126: + The posix_fadvise system call has been changed from an assembly + stub, to a c file that calls an assembly stub. You need to + 'rm -f posix_fadvise.* .depend' in the libc build directory to + avoid using the old assembly stub. + +20071209: + The acpiec(4) driver has been split into two attachments. If you + get ACPI errors before the attachment, please update your kernel + configuration file appropriately or see GENERIC for more details. + +20071115: + The it(4) driver has been renamed to itesio(4) and the old port + argument specified in the kernel configuration file is not valid + anymore. The itesio(4) driver now uses the Super I/O address port + rather than the EC address port. Please update your kernel + configuration file appropriately or see GENERIC for more details. + +20071028: + The pccons(4) driver has been removed from the NetBSD/shark port. + You need to update any custom kernel configuration file you have + to remove any references to pccons (which includes removing the + now useless XSERVER option) and replace them with the correct + entries for the wscons driver. See the GENERIC configuration file + for more details. + +20070913: + A latent bug in dhclient/dhcpd that caused it to be unable to + enumerate interfaces was fixed. The bug began to cause + problems after 20070911 when the kernel's SIOCGIFCONF + implementation was repaired. From 20070529 to 20070911 racoon + could not enumerate interfaces. (These are noted because + normal kernel/userspace version matching hygiene is not + sufficient to avoid this problem.) Ensure that both kernel + and userland are from after 20070913. + +20070703: + nbinstall has been renamed ${MACHINE_GNU_ARCH}-install. It + calls the target-specific strip program, and the logic to pass + down STRIP from make has been removed. This requires a + re-installation of tools. + +20070422: + The way OS emulations lookup filenames inside the emulation root + has been changed. Rather than modify the pathname (and copy back + to userspace) namei() and lookup() directly check the emulation + root. One side effect is that absolute symlinks inside the emulated + root file system will be relative to that file system - unless they + start /../ this is useful when the emulated root is a real install + that has such links. + This might affect symlinks that have been added to reference outside + the emulated root. + +20070412: + The pckbc driver on sgimips IP32 has been removed. Use macekbc + instead. See the GENERIC32_IP3x kernel configuration for an + example. + +20070319: + src/lib/libc/Makefile revision 1.129 broke libc and ld.elf_so + on many platforms due to incorrect flags settings. If you + updated and built after about 20070315, do "nbmake-$arch + cleandir" in src/lib/libc and src/libexec/ld.elf_so to force a + rebuild of object files that might have been built + incorrectly, and ensure that you have at least + src/lib/libc/Makefile 1.130. + +20070210: + src/sys/sys/{sa.h,savar.h} were removed. + find ${OBJDIR} \( -name .depend -o -name '*.d' \) -print \ + | xargs egrep -l '/sa.h|/savar.h' | xargs rm + will allow dependencies on those files to get get rebuilt + +20070209: + The threading model was changed when the newlock2 branch + was merged to NetBSD-current. If you boot with a new + kernel (version 4.99.10), then you also need a new pthread + library (/usr/lib/libpthread.so.0.7). If you boot with + an old kernel, then you need the old pthread library + (/usr/lib/libpthread.so.0.6). Provided you keep the kernel and + the pthread library in sync, old threaded applications should + continue to work with an old or new kernel. Note that named(8) + is the only threaded application in the base system. + +20061214: + Following the move of string_to_flags() and flags_to_string() + from the bin/ls/ sources to libutil, users doing UPDATE builds + will need to do a "make cleandir" in + tools/mtree/, tools/makefs/, tools/binstall/, tools/pax/, + bin/pax/, bin/ls/, usr.sbin/mtree/, usr.sbin/makefs/, + usr.bin/xinstall/, libexec/ftpd/, rescue/, as well + as the installation images in distrib/ + in order to excise stale references to the old stat_flags.h header + file in the ls sources -- stat_flags.h has been removed. + +20061108: + The configure script used in the src/tools/gcc compiler has been + changed to indicate that our libc has ssp support built-in and + does not depend on -lssp and -lssp-nonshared. You'll need to + make clean in src/tools/gcc first to rebuild the compiler. + +20061009: + The sysctl variables net.inet{,6}.tcp{,6}.newreno are no longer + available. Use net.inet{,6}.tcp{,6}.congctl.selected instead. + +20060814: + The vt, vidcconsole, kbd, and rpckbd drivers on acorn32 have been + withdrawn. Use vidcvideo and pckbd instead. See the GENERIC + kernel configuration for an example. X servers from the last + few years should cope. + +20060703: + MPACPI is no more.
