PIE, or position-independent + executables, means all code, including executables and not just + shared libraries, is position-independent and hence able to be + relocated by ASLR, address space layout randomization. + + The change was made in Makefile variables for compiler and + linker flags, for which make(1) does not record dependencies, + hence it is unable to detect that all .o files need rebuilding. + + Partial rebuilds with some modified source files will likely + fail when linking executables, since the linker refuses to mix + position-independent code with position-dependent code in + position-independent executables: + + .../x86_64--netbsd/bin/ld: foo.o: relocation R_X86_64_32 against `...' cannot be used when making a shared object; recompile with -fPIC + +20160401: + Ports switching to GCC 5.3 will need a full "make cleandir". + Some people have found that cleandir is not sufficient, so if + in doubt delete the entire object directory tree for gcc. + +20160306: + NetBSD's regexp implementation is now part of libnbcompat. + Nblex, nbm4, nbpax, nbsed use it and they may crash on + non-NetBSD hosts if linked with stale object files produced + while they included a non-NetBSD regex.h. + In any case, you should "make cleandir" at least these tools + before updating your toolchain. + +20160125: + Dtrace has been enabled by default on some architectures. + When doing an update build, make sure to clean the etc/mtree + object directory before starting the build - otherwise the + needed directories in destdir will not be created. + An easy way to do this is: + cd src/etc/mtree && $TOOLDIR/bin/nbmake-$arch cleandir + +20150818: + New acpica requires "make cleandir" in src/external/bsd/acpica + again. + +20150413: + New acpica requires "make cleandir" and reinstalling yacc + in /usr/src/external/bsd/byacc and /usr/src/tools/yacc and + also "make cleandir" in /usr/src/external/bsd/acpica. + +20150404: + Lint changes require a full rebuild of the tool, so make + sure to build without -u option to build.sh, or manually + do a make cleandir in src/tools/lint1 and + src/usr.bin/xlint. + +20150310: + Improvements to openssl for arm mean that update builds of + the openssl libraries will fail. A make cleandir in + external/bsd/openssl/lib is needed + +20141026: + A mishap during the import of pppd may cause your corruption + in your cvs directory if you happened to do a cvs update + during a short period of time. To fix, just remove the + directory src/external/bsd/ppp/dist/pppd completely + and let cvs restore it on next update. + +20140721: + The src/external/mit/lua/src directory was accidentally created + and then deleted in the CVS repository. If you get errors like + + cvs [update aborted]: cannot open directory + /cvsroot/src/external/mit/lua/src: No such file or directory + + then delete your local copy of that directory tree and try again. + +20140530: + ARM eABI switched to DWARF based exception handling. This requires + rebuilding all C++ code. It is strongly advised to do a clean build. + +20140131: + The new compiler_rt/libc integration moved a few things. It is strongly + advised to do a clean build. At least lib/libc, the compat version(s) + of libc, libkern, rump and the kernels need to be cleaned. + +20131227: + 1. The new ntpd runs in a restricted mode to prevent amplification + attacks. If you need ntpdc to work you need to explicitly enable + mode7 in your config file. Make sure you put the necessary restrict + statements to avoid being exposed. + 2. strncat has moved from lib/libc to common/lib/libc; you might need + to make clean in libc + +20131129: + The GMP sources were updated, and builds will likely fail without + cleaning their build trees for both tools and in-tree, like below. + +20131128: + The MPC and MPFR sources were updated, and builds may require their + tools and in-tree directories cleaned for successful updates. + +20130605: + The kernel option FAST_IPSEC no longer exists, it's been renamed + to IPSEC (and the older IPSEC version removed). + +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. You need to update dbsym in + your $TOOLDIR to build kernels with options SYMTAB_SPACE. 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. If you replace your kernel, + replace your rndctl executable too. + +20111001: + the prop_*_send_syscall() functions from proplib(3) have been + changed and their new version is not backward compatible with the old + one. 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". It may be necessary to remove + the OBJDIR for external/mit/xorg/server/xorg-server/hw/xfree86 + if your update build fails, as the "Xorg" entry there is now a directory. -20000929: - The following make directives are obsoleted. - MKCRYPTO_RSA NOCRYPTO_RSA NOCRYPTO_RC5 NOCRYPTO_IDEA - By default, RSA is built into libcrypto. IDEA and RC5 will not be - bulit into libcrypto. By using MKCRYPTO_{RC5,IDEA}, you can build - additional library libcrypto_{idea,rc5}. - -20000623: - MKCRYPTO and friends added to share/mk/bsd.own.mk. - 'cd share/mk ; make install' needed before make build. - +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 '='. Revision 1.18 of env.c + assumed that this was allowed. Installing a new libc with an + old copy of /usr/bin/env causes env x=1 printenv | grep x= to + break which affects the autoconf tests for dependency finding, + so building gcc will end up printing: + checking dependency style of gcc... none + configure: error: no usable dependency style found + Fix it by rebuilding and re-installing env. + +20101119: + Recent Xorg updates in xsrc/external/mit/ may cause various build + or run-time problems. 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).
