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 + +20060814: + The vt, vidcconsole, kbd, and rpckbd drivers on acorn32 have been + withdrawn.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. We always configure PCI interrupts using ACPI + if we have an ACPI kernel. The option MPACPI_SCANPCI has been renamed + to ACPI_SCANPCI. Thanks to work from fvdl. + +20060627: + socket(2) has changed, and its system call has been versioned. + For userlands with the old version of socket(2), make sure that + your kernel has 'options COMPAT_30' set, or else 'bad system call' + errors will result. + +20060526: + The kernel linker scripts for i386 and xen + (sys/arch/i386/conf/kern.ldscript*) were changed to set the + load address correctly, for the benefit of MULTIBOOT boot loaders + (like Grub). If you use a linker (ld) older than from 2006/04/17, it + will be unable to link the kernel because of a bug and ld will fail + with an error like: + ../../../../arch/i386/conf/kern.ldscript:45 \ + non constant expression for load base + You need to update at least src/gnu/dist/binutils/ld and recompile + and install the linker. If using the build.sh script, the easiest + way is with a "build.sh tools" command, with any other options + that you use normally. When using build.sh, the linker binary is + installed as ${TOOLDIR}/bin/i386--netbsdelf-ld. + +20060131: + the protocol between the sparc64 bootloader (ofwboot) and + the kernel was changed. Before installing a new kernel, + you need to update ofwboot. After a full build, just copy + /usr/mdec/ofwboot to /, or do a rebuild of + src/sys/arch/sparc/stand/ofwboot and install the result to /. + +20050917: + arch/*/conf/std.* was changed to include conf/std, which + contains MI options previously enabled by default. + If you have kernel config files which doesn't include + arch/*/conf/std.*, you need to edit them to include conf/std + to get the previous configuration. + +20050830: + named.conf was moved from /etc/namedb to /etc. + postinstall(8) migrates this during interactive use. + Users of MKUPDATE=yes will need to manually rectify + this in their DESTDIR. + +20050825: + Some data structures in sys/device.h, related to interface + attributes and locator names, were changed. config(1) was + modified to emit the new data structures. + Thus usr.bin/config must be updated (and run on the kernel + configuration file) before a new kernel can be built. + +20050531: + genassym.sh(8) was moved to genassym(1). You need to either build + tools first or install the version of genassym from /usr/bin before + you can build a kernel again. + +20050520: + Because a kernfs bug which xentools relies on was fixed, + xentools up to xentools20-2.0.3nb4 won't work with new kernel. + +20050417: + postinstall(8) was moved from /etc to /usr/sbin and made part + of the "base" set, to make it easier to invoke after an + upgrade. + +20050325: + pcppi(4) was separated in two devices, adding attimer(4). Be sure + to add a config line for an attimer(4) device in your kernel + configuration, or you won't be able to set the pitch of the beep + with wsconsctl. Depending on the default value for the pitch, you + might even not hear any more beep. Also, it is advised to attach both + devices the same way (i.e., both on isa or both on acpi) or the + pcppi(4) device may fail to find the attimer(4) one. + +20050211: + Fixes to tools/Makefile.gnuhost may cause UPDATE=1 builds in + some of the cross tools to fail if they use configure. Some configure's + cache the environment passed in and notice the new environment is + different and abort. Doing a clean in tools/ should be enough to + make a build continue. + +20050109: + Since su is using pam by default now, make sure that you have + /etc/pam.d populated (postinstall will do that automatically + for you). Otherwise su will fail open (i.e. will not require + a password). + +20041229: + Make had a path resolution bug that manifested itself as not + being able to install openpam.3. This bug has been fixed, but + you might need to rebuild make manually first to get through + the build. + +20041201: + Userland programs have been changed to use /dev/bpf instead of + /dev/bpfX. You need to create that device by installing a new + MAKEDEV and running it, or mv /dev/bpf0 /dev/bpf && rm /dev/bpf[0-9]* + +20041006: + + A bug was introduced into /bin/sh (var.c rev 1.35) which causes + variables to not export correctly to subshells in all cases. This + will cause builds to break if that version of /bin/sh is installed + on the system. The proper version of /bin/sh can be verified with: + + ident /bin/sh | grep var + + Any /bin/sh w. version 1.35 will not work and needs to be updated + before attempting a build. + +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, and + ftp-proxy are 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 extension 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 constructors/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 UsePrivilegeSeparation=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.

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.
