1.161 ! dsl 1: $NetBSD: UPDATING,v 1.160 2007/04/12 13:17:56 jmcneill Exp $
1.1 abs 2:
1.123 jmc 3: This file (UPDATING) is intended to be a brief reference to recent
4: changes that might cause problems in the build process, and a guide for
5: what to do if something doesn't work.
1.1 abs 6:
1.123 jmc 7: For a more detailed description of the recommended way to build NetBSD
8: using build.sh, see the BUILDING file.
9:
10: Note that much of the advice in this UPDATING file was written before
11: build.sh existed. Nevertheless, the advice here may be useful for
12: working around specific problems with build.sh.

1.161 ! dsl 19: 20070422:
! 20: The way OS emulations lookup filenames inside the emulation root
! 21: has been changed. Rather than modify the pathname (and copy back
! 22: to userspace) namei() and lookup() directly check the emulation
! 23: root. One side effect is that absolute symlinks inside the emulated
! 24: root filesytem will be relative to that filesystem - unless they
! 25: start /../ this is useful when the emulated root is a real install
! 26: that has such links.
! 27: This might affect symlinks that have been added to reference outside
! 28: the emulated root.
! 29:
1.160 jmcneill 30: 20070412:
31: The pckbc driver on sgimips IP32 has been removed. Use macekbc
32: instead. See the GENERIC32_IP3x kernel configuration for an
33: example.
34:
1.159 gdt 35: 20070319:
36: src/lib/libc/Makefile revision 1.129 broke libc and ld.elf_so
37: on many platforms due to incorrect flags settings. If you
38: updated and built after about 20070315, do "nbmake-$arch
39: cleandir" in src/lib/libc and src/libexec/ld.elf_so to force a
40: rebuild of object files that might have been built
41: incorrectly, and ensure that you have at least
42: src/lib/libc/Makefile 1.130.
43:
1.158 dbj 44: 20070210:
45: src/sys/sys/{sa.h,savar.h} were removed.
46: find ${OBJDIR} \( -name .depend -o -name '*.d' \) -print \
47: | xargs egrep -l '/sa.h|/savar.h' | xargs rm
48: will allow dependencies on those files to get get rebuilt
49:
1.157 apb 50: 20070209:
51: The threading model was changed when the newlock2 branch
52: was merged to NetBSD-current. If you boot with a new
53: kernel (version 4.99.10), then you also need a new pthread
54: library (/usr/lib/libpthread.so.0.7). If you boot with
55: an old kernel, then you need the old pthread library
56: (/usr/lib/libpthread.so.0.6). Provided you keep the kernel and
57: the pthread library in sync, old threaded applications should
58: continue to work with an old or new kernel. Note that named(8)
59: is the only threaded application in the base system.
60:
1.154 he 61: 20061214:
62: Following the move of string_to_flags() and flags_to_string()
63: from the bin/ls/ sources to libutil, users doing UPDATE builds
64: will need to do a "make cleandir" in
65: tools/mtree/, tools/makefs/, tools/binstall/, tools/pax/,
66: bin/pax/, bin/ls/, usr.sbin/mtree/, usr.sbin/makefs/,
1.156 he 67: usr.bin/xinstall/, libexec/ftpd/, rescue/, as well
68: as the installation images in distrib/
1.154 he 69: in order to excise stale references to the old stat_flags.h header
70: file in the ls sources -- stat_flags.h has been removed.
71:
1.152 christos 72: 20061108:
73: The configure script used in the src/tools/gcc compiler has been
74: changed to indicate that our libc has ssp support built-in and
75: does not depend on -lssp and -lssp-nonshared. You'll need to
76: make clean in src/tools/gcc first to rebuild the compiler.
77:
1.151 rpaulo 78: 20061009:
79: The sysctl variables net.inet{,6}.tcp{,6}.newreno are no longer
80: available. Use net.inet{,6}.tcp{,6}.congctl.selected instead.
81:
1.150 bjh21 82: 20060814:
83: The vt, vidcconsole, kbd, and rpckbd drivers on acorn32 have been
84: withdrawn. Use vidcvideo and pckbd instead. See the GENERIC
85: kernel configuration for an example. X servers from the last
86: few years should cope.
87:
1.149 christos 88: 20060703:
89: MPACPI is no more. We always configure PCI interrupts using ACPI
90: if we have an ACPI kernel. The option MPACPI_SCANPCI has been renamed
91: to ACPI_SCANPCI. Thanks to work from fvdl.
92:
1.148 dogcow 93: 20060627:
94: socket(2) has changed, and its system call has been versioned.
95: For userlands with the old version of socket(2), make sure that
96: your kernel has 'options COMPAT_30' set, or else 'bad system call'
97: errors will result.
98:
1.146 pavel 99: 20060526:
1.147 christos 100: The kernel linker scripts for i386 and xen
101: (sys/arch/i386/conf/kern.ldscript*) were changed to set the
1.146 pavel 102: load address correctly, for the benefit of MULTIBOOT boot loaders
103: (like Grub). If you use a linker (ld) older than from 2006/04/17, it
1.147 christos 104: will be unable to link the kernel because of a bug and ld will fail
105: with an error like:
106: ../../../../arch/i386/conf/kern.ldscript:45 \
107: non constant expression for load base
108: You need to update at least src/gnu/dist/binutils/ld and recompile
109: and install the linker. If using the build.sh script, the easiest
110: way is with a "build.sh tools" command, with any other options
111: that you use normally. When using build.sh, the linker binary is
112: installed as ${TOOLDIR}/bin/i386--netbsdelf-ld.
113:
1.145 martin 114: 20060131:
115: the protocol between the sparc64 bootloader (ofwboot) and
116: the kernel was changed. Before installing a new kernel,
117: you need to update ofwboot. After a full build, just copy
118: /usr/mdec/ofwboot to /, or do a rebuild of
119: src/sys/arch/sparc/stand/ofwboot and install the result to /.
120:
1.144 yamt 121: 20050917:
122: arch/*/conf/std.* was changed to include conf/std, which
123: contains MI options previously enabled by default.
124: If you have kernel config files which doesn't include
125: arch/*/conf/std.*, you need to edit them to include conf/std
126: to get the previous configuration.
127:
1.143 lukem 128: 20050830:
129: named.conf was moved from /etc/namedb to /etc.
130: postinstall(8) migrates this during interactive use.
131: Users of MKUPDATE=yes will need to manually rectify
132: this in their DESTDIR.
133:
1.142 drochner 134: 20050825:
135: Some data structures in sys/device.h, related to interface
136: attributes and locator names, were changed. config(1) was
137: modified to emit the new data structures.
138: Thus usr.bin/config must be updated (and run on the kernel
139: configuration file) before a new kernel can be built.
140:
1.139 christos 141: 20050531:
1.141 augustss 142: genassym.sh(8) was moved to genassym(1). You need to either build
143: tools first or install the version of genassym from /usr/bin before
1.139 christos 144: you can build a kernel again.
145:
1.140 yamt 146: 20050520:
147: Because a kernfs bug which xentools relies on was fixed,
148: xentools up to xentools20-2.0.3nb4 won't work with new kernel.
149:
1.138 lukem 150: 20050417:
151: postinstall(8) was moved from /etc to /usr/sbin and made part
152: of the "base" set, to make it easier to invoke after an
153: upgrade.
154:
1.136 cube 155: 20050325:
156: pcppi(4) was separated in two devices, adding attimer(4). Be sure
157: to add a config line for an attimer(4) device in your kernel
158: configuration, or you won't be able to set the pitch of the beep
1.137 cube 159: with wsconsctl. Depending on the default value for the pitch, you
160: might even not hear any more beep. Also, it is advised to attach both
161: devices the same way (i.e., both on isa or both on acpi) or the
162: pcppi(4) device may fail to find the attimer(4) one.
1.136 cube 163:
1.135 jmc 164: 20050211:
165: Fixes to tools/Makefile.gnuhost may cause UPDATE=1 builds in
166: some of the cross tools to fail if they use configure. Some configure's
167: cache the environment passed in and notice the new environment is
168: different and abort. Doing a clean in tools/ should be enough to
169: make a build continue.
170:
1.134 christos 171: 20050109:
172: Since su is using pam by default now, make sure that you have
173: /etc/pam.d populated (postinstall will do that automatically
174: for you). Otherwise su will fail open (i.e. will not require
175: a password).
176:
1.133 christos 177: 20041229:
178: Make had a path resolution bug that manifested itself as not
179: being able to install openpam.3. This bug has been fixed, but
180: you might need to rebuild make manually first to get through
181: the build.
182:
1.130 christos 183: 20041201:
184: Userland programs have been changed to use /dev/bpf instead of
185: /dev/bpfX. You need to create that device by installing a new
1.131 wiz 186: MAKEDEV and running it, or mv /dev/bpf0 /dev/bpf && rm /dev/bpf[0-9]*
1.99 mrg 187:
1.129 jmc 188: 20041006:
189:
190: A bug was introduced into /bin/sh (var.c rev 1.35) which causes
191: variables to not export correctly to subshells in all cases. This
192: will cause builds to break if that version of /bin/sh is installed
193: on the system. The proper version of /bin/sh can be verified with:
194:
195: ident /bin/sh | grep var
196:
197: Any /bin/sh w. version 1.35 will not work and needs to be updated
198: before attempting a build.
199:
1.127 christos 200: 20041001:
201: The ipfilter kernel sources moved from sys/netinet to
202: dist/sys/ipf/netinet. Due to the move some Makefile
203: dependencies are now dangling requiring a make cleandir
1.128 he 204: before they work again (kdump, ktruss, rescue, ipf, and
205: ftp-proxy are the victims).
1.127 christos 206:
1.125 atatat 207: 20040715:
208: The rc.d/sendmail script now uses a heuristic to determine
209: if sendmail should be started at boot time. It checks the
210: contents of /etc/mailer.conf, /etc/mail/submit.cf, and the
211: owner and mode of the sendmail binary to see if any changes
212: to the mail infrastructure have been made. If no changes
213: are detected, it will start an SMTP listener.
214:
215: Setting sendmail=NO in /etc/rc.conf will override this.
216:
217: If you are only using sendmail by default and only for
218: local delivery, it is important that you also update your
219: sendmail.cf so that the SMTP listener only listens on the
220: loopback interface.
221:
222: 20040715:
223: The method by which athhal-elf.o gets pulled into i386
224: kernel builds has been changed again. The latest version
225: of bsd.files.mk is no longer required.
226:
1.124 jmc 227: 20040621:
228: Due to the recent rototill of tools/compat it's crucial one starts
229: from a clean objdir under tools/*.
230:
231: This is mostly due to generated files (yacc and lex sources) needing
1.125 atatat 232: to be generated with new rules from bsd.hostprog.mk.
1.124 jmc 233:
234: The safest course is to rm -rf all objects under tools before building.
235:
1.121 lukem 236: 20040516:
237: The end-user modifiable X11 configuration has been moved
238: from /usr/X11R6/lib/X11/<dir> to /etc/X11/<dir>.
239: Ensure that src and xsrc is up to date, and run
240: "make cleandir" in src/x11 before your next build.
241:
1.126 lukem 242: postinstall currently doesn't migrate the files from
243: /usr/X11R6/lib/X11/* to /etc/X11/* although it does
244: detect that this needs to occur, so you'll have to
245: manually move these files yourself.
246:
1.119 atatat 247: 20040426:
248: Support for the original dynamic sysctl node structure has
249: been removed in favor of the newer layout. This affects
250: consumers of the create and delete interface, as well as
251: the dynamic discovery mechanism. This is believed only to
252: be the sysctl(8) binary itself, at this point in time, so
253: the only effect of this should be that a sysctl binary
254: built from sources dated between 2003/12/04 and 2004/03/24
255: will not work on a kernel built from sources dated after
256: 2004/04/25. If you need a new sysctl binary but build.sh
257: does not work, make sure that your revision of
1.120 atatat 258: src/sys/sys/sysctl.h is 1.112 (or later), and then the
259: do the following:
1.119 atatat 260:
1.120 atatat 261: cd /usr/src (or wherever your source tree is)
262: make USETOOLS=no includes
263: cd lib/libc
264: make USETOOLS=no dependall install
265: cd ../../sbin/sysctl
1.119 atatat 266: make USETOOLS=no dependall install
267:
1.122 itojun 268: If you are using older sysctl binary, GNU autoconf would fail to
269: identify your machine architecture, and tries to build binary for
270: "unknown-unknown-netbsd20F" or something like that. if that happens,
271: make sure to follow the above steps.
272:
1.118 dbj 273: 20040425:
274: The ffs superblock issues listed below under 20040109 and 20030402
275: are now automatically addressed by the /etc/rc.d/fixsb script or by
276: sysinst when it checks a a filesystem. The manual fsck_ffs -b16 -c4
277: invocation mentioned below will continue to work and is now
278: automated by those scripts. Note that under certain circumstances,
279: affected filesystems upgraded to a -current kernel first before
280: upgrading their userland with the fixsb and fsck_ffs fixes may
281: encounter a 'freeing free inode' panic when writing to the affected
282: filesystem, so it is a good idea to repair the filesystem as soon as
283: possible. For more details on the fixsb script, see pr install/25138.
284:
1.115 christos 285: 20040418:
1.121 lukem 286: statfs(2) and friends have been replaced with statvfs(2). Before
1.115 christos 287: installing a newly build userland make sure that you are running
288: a newly built kernel with COMPAT_20 set. In addition your libc
289: build might not work (undefined SYS_statfs symbol) because make
290: clean does not know how to remove files it does not know about
1.116 christos 291: anymore. Manually remove all generated .S sources and objects
292: from the libc build directory.
1.115 christos 293:
1.114 jmc 294: 20040326:
295: The method by which athhal-elf.o gets pulled into i386 kernel builds
1.117 jmc 296: has been changed. The file is now stored as a uuencoded file in CVS
1.114 jmc 297: and the generated Makefile will use the new .uue rules from bsd.file.mk
298: to build it.
299:
300: This means you must have the latest bsd.files.mk installed when
301: building a kernel without USETOOLS=yes.
302:
1.113 dan 303: 20040318:
304: A bug in the cgd(4) blowfish code was corrected, without
305: provision of backwards compatibility, after several public
306: notices over several months. Users of cgd with blowfish cipher
307: ONLY must dump their data before updating their kernels, and
308: recreate cgd's and restore data using the new kernel. See
309: (recent message to current-users, URL when mail-index has updated)
310:
1.108 bjh21 311: 20040313:
312: On acorn32, the opms and qms drivers have been withdrawn, and
313: the old wsqms driver is now called qms. Kernel config files
314: will need updating. See the ones in sys/arch/acorn32/conf
315: for examples.
316:
1.106 bjh21 317: 20040125:
318: On acorn32, the beep and sysbeep devices are no longer
319: needed, and will need to be deleted from kernel configuration
320: files.
1.105 bjh21 321:
1.102 dbj 322: 20040109:
323: Compatibility for old ffs superblock layouts has been
324: added, and the restrictive fsck checks have been reenabled
325: when using those layouts. If you have been using -current
326: since 20030402, you may find that fsck again signals fatal
1.110 dbj 327: superblock mismatches. To repair, make sure you have
1.111 simonb 328: an updated fsck_ffs and then you can use fsck_ffs -b 16 -c 4
1.109 dbj 329: to complete the filesystem upgrade. A message has
1.111 simonb 330: been added to the kernel which should detect this problem.
331: See the following discussion for more information:
1.112 keihan 332: http://mail-index.NetBSD.org/current-users/2004/01/11/0022.html
1.102 dbj 333:
1.99 mrg 334: 20031203:
1.100 keihan 335: New binutils builds may fail due to old dependencies.
1.99 mrg 336: It's necessary to "make cleandir" to ensure that
337: the dependencies will be rebuilt correctly.
1.98 wiz 338:

346: the dependencies will be rebuilt correctly.
1.96 christos 347:
1.109 dbj 348: 20031007:
1.153 reed 349: A sign extension bug was fixed which set all the high bits
1.111 simonb 350: of our newly expanded ffs fs_flags. This should only
351: affect users who installed or upgraded in September of 2003.
1.109 dbj 352: A small utility program was posted to tech-kern which
1.111 simonb 353: should fix this problem, and a warning message was added
354: to the kernel which should discover and warn about it. See
355: http://mail-index.NetBSD.org/tech-kern/2003/10/07/0005.html
1.109 dbj 356:
1.96 christos 357: 20030906:
358: With the addition of siginfo support the old signal trampoline
359: code has been deprecated to COMPAT_16. Make sure that your running
360: kernel has COMPAT_16 enabled before building userland.
1.94 christos 361:
362: 20030801:
1.95 wiz 363: With the new openssl, there is some header and library shuffling.
1.94 christos 364: rm -f /usr/include/des.h /usr/include/kerberosIV/* /lib/libdes* \
1.95 wiz 365: /usr/lib/libdes* before building.
1.92 wiz 366:
367: 20030703:
368: Texinfo was updated to 4.6. To avoid failures when trying to
369: build the included texinfo files, do:
370:
371: cd src/gnu/usr.bin/texinfo
372: make MKINFO=no dependall install
1.90 wiz 373:
374: 20030630:
1.101 junyoung 375: Groff was updated to 1.19; it's probably necessary to do
1.91 wiz 376: cd share/mk && make install
1.90 wiz 377: cd src/gnu/usr.bin/groff
378: make MKMAN=no dependall install
379: (untested).
1.89 christos 380:
381: 20030516:
382: Due to bugs in the export handling code, invalid export lines
383: were accepted before and caused the kernel to panic when
384: mountd got restarted because it freed memory that had already
385: been freed. This has been fixed and the kernel checks
386: export addresses very strictly. If you upgrade your kernel,
387: make sure you also upgrade mountd, because if your export
388: file contains lines with an old inet4 address syntax (i.e.
389: a.b.c or a.b or a), they will get rejected by the new kernel.
1.87 bjh21 390:
391: 20030402:
392: The superblock layout for FFS was changed. If you have 1.6
393: fsck binaries, they will signal a fatal superblock mismatch
394: with the first alternate, because they compare too many
395: fields (even ones that aren't useful). If possible, upgrade
396: your fsck_ffs binary before using a new kernel.
397: None of this signals actual filesystem damage.
1.85 atatat 398:
399: 20030324:
400: sendmail version 8.12.8 was imported. Since sendmail is
401: now setgid to the smmsp group, and runs in "collection"
402: mode for most common activities, there is a new config
403: file called submit.cf that needs to live in /etc/mail.
404: The generic submit.cf sample in /usr/share/sendmail/cf
405: is named netbsd-msp.cf. Upgrading your regular sendmail
406: configuration file is also strongly advised.
407:
408: See the section named "MESSAGE SUBMISSION PROGRAM" in
409: the updated /usr/share/sendmail/README file for more
410: information.
1.82 wiz 411:

413: Texinfo was updated to 4.3. To avoid failures when trying to
414: build the included texinfo files, do:

434: alternate location to look up users & groups (instead
435: of the host system passwd(5) and group(5) databases).
436:
437: The build system was modified to take advantage of
438: this option (using ${NETBSDSRCDIR}/etc), so if you
1.83 kei 439: use USETOOLS==no, you may have to rebuild and
1.80 lukem 440: reinstall usr.bin/xinstall first.

458: The C run-time support files crtbegin.o and crtend.o
459: (and their companions crtbeginS.o and crtendS.o) were
460: split up, with new crti.o and crtn.o files resulting.
461: This means that libtool needs to be rebuilt once the
462: new libraries are installed. The process of rebuilding
463: libtool will cause it to automatically notice the new
464: required files, but it *must* be rebuilt in order to
465: do this.
466:
467: An out-of-date libtool will result in shared libraries
468: which lack _init() and _fini() routines, which means that
1.153 reed 469: their global constructors/destructors will not be invoked.

472: A bug related to how ARM ELF objects were tagged has been
473: corrected.
474:
475: NetBSD ARM ELF uses the soft-VFP floating point model by
476: default. However, the assembler lacked support for marking
477: objects as using the VFP floating point format, and the
1.79 wiz 478: compiler was not properly passing the flag indicating "soft-VFP"
1.75 thorpej 479: to the assembler.
480:
481: Unfortunately, this means that the linker will now consider
482: old (i.e. not marked "softvfp") NetBSD ARM ELF objects to be
483: incompatible with new (properly marked) objects.
484:
485: The problem will only manifest itself if you attempt to compile
486: a new program using the fixed toolchain, and link that program
487: against old libraries which do not have the proper "softvfp"
488: markings. ALL OF YOUR EXISTING BINARIES AND SHARED LIBRARIES
489: WILL CONTINUE TO WORK PROPERLY.
490:
491: The only work-around for the problem is to recompile all of
492: the libraries on the system. The easiest way to do this for
1.79 wiz 493: system libraries is to install a binary snapshot; they are
1.93 salo 494: generally available on releng.NetBSD.org. Any packages you
1.75 thorpej 495: have installed which supply libraries will have to be recompiled
496: if you wish to link new programs against those libraries.
497:
498: If you have questions about this matter, please contact
1.93 salo 499: port-arm@NetBSD.org.

818: Hints for a more successful build:
819: ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
1.123 jmc 820: Use build.sh, but do not use its "expert mode":
1.132 jmmv 821: This will automatically build the tools in the
1.123 jmc 822: correct order, and it will keep the tools and the
823: new build products from interfering with the running
824: system. This will allow you to ignore most of the
825: other advice in this file.
1.2 mrg 826: Build a new kernel first:
827: This makes sure that any new system calls or features
828: expected by the new userland will be present. This
829: helps to avoid critical errors when upgrading.
1.1 abs 830: Use object directories:
831: This helps to keep stale object
832: files from polluting the build if a Makefile "forgets"
833: about one. It also makes it easier to clean up after
834: a build. It's also necessary if you want to use the
835: same source tree for multiple machines.
1.123 jmc 836: To use object directories with build.sh:
837: a) invoke build.sh with the "-M" or "-O" options.
838: To use object directories without using build.sh:
1.1 abs 839: a) cd /usr/src ; make cleandir
1.2 mrg 840: b) Add "OBJMACHINE=yes" to /etc/mk.conf
841: c) Add "MKOBJDIRS=yes" to /etc/mk.conf
1.1 abs 842: d) cd /usr/src ; make build
1.2 mrg 843: Note that running "make obj" in a directory will create
844: in obj.$MACHINE directory.
1.1 abs 845: Build to a DESTDIR:
1.123 jmc 846: This helps to keep old installed files (especially libraries)
847: from interfering with the new build.
848: To build to a DESTDIR with build.sh, use the "-D" option.
849: To build to a DESTDIR without using build.sh, set the DESTDIR
850: environment variable before running make build. It should be
851: set to the pathname of an initially empty directory.
852: Problems: if you do not use build.sh, you might need to
853: update critical utilities without using DESTDIR since
854: nothing is executed from what is installed in DESTDIR.
855: (See critical utils, below.)
1.1 abs 856: Build often:
857: This keeps critical utilities current enough to not choke
858: on any other part of the source tree that depends on up to
1.123 jmc 859: date functionality. If you use build.sh, you should not have
860: this problem.
1.1 abs 861:
862: What to do if things don't work:
863: ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
864: When things don't work there is usually a few things that commonly
865: should be done.
866: 1) make includes
867: This should be done automatically by make build.
868: 2) cd share/mk && make install
869: Again, automatically done by make build.
870:

872: ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
873: To make sure you rebuild something correctly you want to do
874: something like the following:
875: 1) Make sure the includes and .mk files are up to date.
876: 2) Make sure any program used to build the particular
877: utility is up to date. (yacc, lex, etc...)
878: 3) cd ...path/to/util...
