! 12: The ffs superblock issues listed below under 20040109 and 20030402
! 13: are now automatically addressed by the /etc/rc.d/fixsb script or by
! 14: sysinst when it checks a a filesystem. The manual fsck_ffs -b16 -c4
! 15: invocation mentioned below will continue to work and is now
! 16: automated by those scripts. Note that under certain circumstances,
! 17: affected filesystems upgraded to a -current kernel first before
! 18: upgrading their userland with the fixsb and fsck_ffs fixes may
! 19: encounter a 'freeing free inode' panic when writing to the affected
! 20: filesystem, so it is a good idea to repair the filesystem as soon as
! 21: possible. For more details on the fixsb script, see pr install/25138.

1.115 christos 23: 20040418:
24: Statfs(2) and friends have been replaced with statvfs(2). Before
25: installing a newly build userland make sure that you are running
26: a newly built kernel with COMPAT_20 set. In addition your libc
27: build might not work (undefined SYS_statfs symbol) because make
28: clean does not know how to remove files it does not know about
1.116 christos 29: anymore. Manually remove all generated .S sources and objects
30: from the libc build directory.
1.115 christos 31:
1.114 jmc 32: 20040326:
33: The method by which athhal-elf.o gets pulled into i386 kernel builds
1.117 jmc 34: has been changed. The file is now stored as a uuencoded file in CVS
1.114 jmc 35: and the generated Makefile will use the new .uue rules from bsd.file.mk
36: to build it.
37:
38: This means you must have the latest bsd.files.mk installed when
39: building a kernel without USETOOLS=yes.
40:
1.113 dan 41: 20040318:
42: A bug in the cgd(4) blowfish code was corrected, without
43: provision of backwards compatibility, after several public
44: notices over several months. Users of cgd with blowfish cipher
45: ONLY must dump their data before updating their kernels, and
46: recreate cgd's and restore data using the new kernel. See
47: (recent message to current-users, URL when mail-index has updated)
48:
1.108 bjh21 49: 20040313:
50: On acorn32, the opms and qms drivers have been withdrawn, and
51: the old wsqms driver is now called qms. Kernel config files
52: will need updating. See the ones in sys/arch/acorn32/conf
53: for examples.
54:
1.106 bjh21 55: 20040125:
56: On acorn32, the beep and sysbeep devices are no longer
57: needed, and will need to be deleted from kernel configuration
58: files.
1.105 bjh21 59:
1.102 dbj 60: 20040109:
61: Compatibility for old ffs superblock layouts has been
62: added, and the restrictive fsck checks have been reenabled
63: when using those layouts. If you have been using -current
64: since 20030402, you may find that fsck again signals fatal
1.110 dbj 65: superblock mismatches. To repair, make sure you have
1.111 simonb 66: an updated fsck_ffs and then you can use fsck_ffs -b 16 -c 4
1.109 dbj 67: to complete the filesystem upgrade. A message has
1.111 simonb 68: been added to the kernel which should detect this problem.
69: See the following discussion for more information:
1.112 keihan 70: http://mail-index.NetBSD.org/current-users/2004/01/11/0022.html
1.102 dbj 71:
1.99 mrg 72: 20031203:
1.100 keihan 73: New binutils builds may fail due to old dependencies.
1.99 mrg 74: It's necessary to "make cleandir" to ensure that
75: the dependencies will be rebuilt correctly.
1.98 wiz 76:
77: 20031111:
78: A newer mkdep is needed. Error noting that is
79: cc: Ambiguous abbreviation --
1.97 lukem 80:
81: 20031008:
82: /usr/include/sys/disklabel_mbr.h was removed.
83: It's necessary to "make cleandir" to ensure that
84: the dependencies will be rebuilt correctly.
1.96 christos 85:
1.109 dbj 86: 20031007:
1.111 simonb 87: A sign exension bug was fixed which set all the high bits
88: of our newly expanded ffs fs_flags. This should only
89: affect users who installed or upgraded in September of 2003.
1.109 dbj 90: A small utility program was posted to tech-kern which
1.111 simonb 91: should fix this problem, and a warning message was added
92: to the kernel which should discover and warn about it. See
93: http://mail-index.NetBSD.org/tech-kern/2003/10/07/0005.html
1.109 dbj 94:
1.96 christos 95: 20030906:
96: With the addition of siginfo support the old signal trampoline
97: code has been deprecated to COMPAT_16. Make sure that your running
98: kernel has COMPAT_16 enabled before building userland.
1.94 christos 99:
100: 20030801:
1.95 wiz 101: With the new openssl, there is some header and library shuffling.
1.94 christos 102: rm -f /usr/include/des.h /usr/include/kerberosIV/* /lib/libdes* \
1.95 wiz 103: /usr/lib/libdes* before building.
1.92 wiz 104:
105: 20030703:
106: Texinfo was updated to 4.6. To avoid failures when trying to
107: build the included texinfo files, do:
108:
109: cd src/gnu/usr.bin/texinfo
110: make MKINFO=no dependall install
1.90 wiz 111:
112: 20030630:
1.101 junyoung 113: Groff was updated to 1.19; it's probably necessary to do
1.91 wiz 114: cd share/mk && make install
1.90 wiz 115: cd src/gnu/usr.bin/groff
116: make MKMAN=no dependall install
117: (untested).
1.89 christos 118:
119: 20030516:
120: Due to bugs in the export handling code, invalid export lines
121: were accepted before and caused the kernel to panic when
122: mountd got restarted because it freed memory that had already
123: been freed. This has been fixed and the kernel checks
124: export addresses very strictly. If you upgrade your kernel,
125: make sure you also upgrade mountd, because if your export
126: file contains lines with an old inet4 address syntax (i.e.
127: a.b.c or a.b or a), they will get rejected by the new kernel.
1.87 bjh21 128:
129: 20030402:
130: The superblock layout for FFS was changed. If you have 1.6
131: fsck binaries, they will signal a fatal superblock mismatch
132: with the first alternate, because they compare too many
133: fields (even ones that aren't useful). If possible, upgrade
134: your fsck_ffs binary before using a new kernel.
135: None of this signals actual filesystem damage.
1.85 atatat 136:
137: 20030324:
138: sendmail version 8.12.8 was imported. Since sendmail is
139: now setgid to the smmsp group, and runs in "collection"
140: mode for most common activities, there is a new config
141: file called submit.cf that needs to live in /etc/mail.
142: The generic submit.cf sample in /usr/share/sendmail/cf
143: is named netbsd-msp.cf. Upgrading your regular sendmail
144: configuration file is also strongly advised.
145:
146: See the section named "MESSAGE SUBMISSION PROGRAM" in
147: the updated /usr/share/sendmail/README file for more
148: information.
1.82 wiz 149:
150: 20030117:
151: Texinfo was updated to 4.3. To avoid failures when trying to
152: build the included texinfo files, do:
153:
154: cd src/gnu/usr.bin/texinfo
155: make MKINFO=no dependall install
1.81 lukem 156:
157: 20021223:
158: The METALOG format changed slightly, to remove the leading
159: "${DESTDIR}" from path names.
160: This only affects people building with UNPRIVED.
161: For complete safety, remove the DESTDIR entirely and
162: update tools/mtree, before running make build.
1.88 itojun 163:
164: 20021219:
165: CVS repository layout was changed. See the following for details
166: if you are using (anonymous) cvs to update your tree.
167:
1.93 salo 168: http://mail-index.NetBSD.org/netbsd-announce/2002/12/19/0000.html
1.80 lukem 169:
170: 20021219:
171: install(1) had a '-N dbdir' option added, to specify an
172: alternate location to look up users & groups (instead
173: of the host system passwd(5) and group(5) databases).
174:
175: The build system was modified to take advantage of
176: this option (using ${NETBSDSRCDIR}/etc), so if you
1.83 kei 177: use USETOOLS==no, you may have to rebuild and
1.80 lukem 178: reinstall usr.bin/xinstall first.
1.78 lukem 179:
180: 20021130:
181: fparseln(3) moved from libutil to libc.
182: If building to DESTDIR=/, reinstall the includes
183: and rebuild libc:
184: make includes
185: make do-lib-libc
186: If using build.sh, "cd tools/compat && make clean"
187: before rebuilding the tools.
1.77 lukem 188:
189: 20021126:
190: The mk.conf(5) variable SYS_INCLUDE has been deprecated,
191: including the optional "SYS_INCLUDE=symlinks" support.
192: All header files, including <sys/*.h> are copied into
193: /usr/include.
1.76 thorpej 194:
195: 20021121:
196: The C run-time support files crtbegin.o and crtend.o
197: (and their companions crtbeginS.o and crtendS.o) were
198: split up, with new crti.o and crtn.o files resulting.
199: This means that libtool needs to be rebuilt once the
200: new libraries are installed. The process of rebuilding
201: libtool will cause it to automatically notice the new
202: required files, but it *must* be rebuilt in order to
203: do this.
204:
205: An out-of-date libtool will result in shared libraries
206: which lack _init() and _fini() routines, which means that
207: their global contructors/destructors will not be invoked.
1.75 thorpej 208:
209: 20021121:
210: A bug related to how ARM ELF objects were tagged has been
211: corrected.
212:
213: NetBSD ARM ELF uses the soft-VFP floating point model by
214: default. However, the assembler lacked support for marking
215: objects as using the VFP floating point format, and the
1.79 wiz 216: compiler was not properly passing the flag indicating "soft-VFP"
1.75 thorpej 217: to the assembler.
218:
219: Unfortunately, this means that the linker will now consider
220: old (i.e. not marked "softvfp") NetBSD ARM ELF objects to be
221: incompatible with new (properly marked) objects.
222:
223: The problem will only manifest itself if you attempt to compile
224: a new program using the fixed toolchain, and link that program
225: against old libraries which do not have the proper "softvfp"
226: markings. ALL OF YOUR EXISTING BINARIES AND SHARED LIBRARIES
227: WILL CONTINUE TO WORK PROPERLY.
228:
229: The only work-around for the problem is to recompile all of
230: the libraries on the system. The easiest way to do this for
1.79 wiz 231: system libraries is to install a binary snapshot; they are
1.93 salo 232: generally available on releng.NetBSD.org. Any packages you
1.75 thorpej 233: have installed which supply libraries will have to be recompiled
234: if you wish to link new programs against those libraries.
235:
236: If you have questions about this matter, please contact
1.93 salo 237: port-arm@NetBSD.org.
1.73 provos 238:
239: 20021011:
240: Systrace has been improved to support privilege elevation.
241: Updating the kernel requires the userland part of systrace
1.79 wiz 242: to be rebuilt.
1.72 thorpej 243:
244: 20021010:
245: The config(8) grammar was changed to allow options to register
246: dependencies on attributes, as well as other options. Users
247: must update and reinstall usr.sbin/config before building a new
248: kernel.
1.70 thorpej 249:
250: 20021009:
251: A new attribute dependency syntax was introduced to config(8),
252: which is now used by the SCSI configuration description. Users
1.71 wiz 253: must update and reinstall usr.sbin/config before building a new
1.70 thorpej 254: kernel.
1.69 thorpej 255:
256: 20021003:
257: Several changes have been made to the autoconfiguration
258: framework. Users must update and reinstall usr.sbin/config
259: before building a new kernel.
1.74 jschauma 260:
261: 20021001:
262: The i386mp branch has been merged. To compile a kernel, users
263: will need to add the option 'cpu* at mainbus?' to their configuration
264: file. Multiprocessor kernels will need
265: ioapic* at mainbus? apid ?
266: options MULTIPROCESSOR
267: options COM_MPLOCK
1.68 lukem 268:
269: 20020922:
270: MKDYNAMICROOT=yes enabled by default, which means that
271: certain shared libraries are installed into /lib, the shared
272: linker is installed into /libexec, and all programs in /bin
273: and /sbin are dynamically linked.
274: If you do not use "make build", you should ensure that
275: you have the libraries and shared linker in the new locations,
276: with:
277: make do-lib-csu do-lib-libc do-lib do-gnu-lib do-ld.elf_so
1.67 lukem 278:
279: 20020917:
280: USE_NEW_TOOLCHAIN has been replaced with:
281: - TOOLCHAIN_MISSING -- set to "yes" on platforms for which
282: there is no working in-tree toolchain (hppa, ns32k, sh5,
283: x86_64).
284: - EXTERNAL_TOOLCHAIN -- if defined by the user, points to the
1.79 wiz 285: root of an external toolchain (e.g. /usr/local/gnu). This
1.67 lukem 286: enables the cross-build framework even for TOOLCHAIN_MISSING
287: platforms.
1.66 gehenna 288:
289: 20020906:
290: gehenna-devsw has been merged into the trunk. Need to update and
1.79 wiz 291: reinstall usr.sbin/config before building the kernel.
1.65 lukem 292:
293: 20020822:
294: Crunched rescue tools (contents of /bin and /sbin, plus others)
295: are now provided in /rescue.
296:
297: To ensure that these are built statically linked (no matter
298: what the setting of LDSTATIC is), use a crunchgen(1) built
299: from sources newer than 20020820 (see the next entry).
300:
301: 20020820:
302: crunchgen(1) changed to ensure that the generated program
303: is statically linked.
304:
305: Solution: update and reinstall usr.bin/crunch
1.84 grant 306:
307: 20020605:
308: smmsp user/group has been added for sendmail.
309:
310: Add the following into /etc/group:
311:
312: smmsp:*:17:
313:
314: and the following to /etc/master.passwd (via vipw):
315:

1.61 itojun 317:
318: 20020515:
319: sshd user/group has been added. Need to hand add this in, or sshd
320: will not let you log in (with default, or UsePrivlegeSeparation=yes)
321:
322: Add the following into /etc/group:
323:
324: sshd:*:16:

327:
1.63 enami 328: sshd:*:16:16::0:0:& pseudo-user:/var/chroot/sshd:/sbin/nologin
1.61 itojun 329:
1.79 wiz 330: Also /var/chroot/sshd directory needs to be present (digged as part of
331: the build process).
1.60 sommerfe 332:
333: 20020426:
334: NBUILDJOBS obsoleted in favor of just using -j.
1.59 lukem 335:
336: 20020426:
337: etc/postinstall added, which performs various checks for
338: configuration file updates and changes, and can fix most of
339: the problems identified.
340: This should make it much easier to upgrade a system's
341: configuration from earlier systems (as far back as NetBSD 1.5).
1.56 lukem 342:
343: 20020320:
1.79 wiz 344: <bsd.lib.mk> needs a new install(1) for its "-a cmd" support.
345: Build and install at usr.bin/xinstall before the build.
1.56 lukem 346:
1.55 itojun 347: 20020319:
1.79 wiz 348: Raw IPv6 socket now makes strict checking for sa_family and sa_len
349: on send(2) operation. Be sure to have sbin/rtsol and usr.sbin/rtsold
1.55 itojun 350: newer than November 2001 when you upgrade the kernel.
351:
1.54 itojun 352: 20020311:
353: ssh configuration files were moved from /etc to /etc/ssh. Beware
354: if you restart your machine from remote. Note that sshd.conf needs
355: to be changed (due to the use of "/etc" inside).
356:
357: 20020223:
1.53 matt 358: Users of the VAX port will need to rebuild and install gas
359: so it deal with the now present register prefix used in all
360: the VAX assembly files.
361:
1.50 itojun 362: 20020118:
363: ntpd user/group has been added. Need to hand add this in or builds
364: will break as mtree aborts early.
365:
366: Add the following into /etc/group:
367:
368: ntpd:*:15:
369:
370: and the following to /etc/master.passwd (via vipw):
371:

1.49 jmc 374: 20011207:
375: If you're attempting to build a snapshot on sparc64 and are getting
376: reloc errors from the toolchain groff binary this means your native
377: toolchain has some broken C++ bits.
378:
379: To fix:
380:
381: Build a new toolchain (i.e. build.sh -t)
382: Use the new toolchain to build and install natively (i.e. /usr/lib)
383:
384: gnu/lib/libgcc
1.51 pooka 385: gnu/lib/libstdc++
1.49 jmc 386:
387: After this a snapshot will be able to be built.
388:
1.47 jmc 389: 20011201:
390: In order for a sparc64 build to work you must have a working awk. If
391: you've built and installed a system with the new toolchain up to this
1.52 wiz 392: point you do not have a working awk as its ability to do floating
1.47 jmc 393: point is broken.
394:
395: To build:
396:
397: remake and install gnu/lib/libgcc
398: remake and install gnu/usr.bin/gawk into /usr/bin (make sure it links
1.48 jmc 399: against the new libgcc.a)
1.47 jmc 400:
1.46 thorpej 401: 20011128:
402: Kernel config information was changed to use defflag in
403: the various "files" files. Bug fixes to config(8) are
404: required in order for this to work properly. Make sure
405: to build and install in usr.sbin/config before attempting
406: to build a new kernel.
407:
1.45 yamt 408: 20011030:
409: libc/locale/wcstod.c now needs new lint(1). Update lint(1)
410: before building libc.

1.44 tv 412: 20011029:
413: The new document BUILDING.mdoc (view with nroff | more, or
414: see pre-generated .txt and .html versions) describes the build
415: procedure in great detail. BUILDING, and the USE_NEW_TOOLCHAIN
416: build process, are intended in the long run to replace this
417: manual update log.
418:
419: Users building a USE_NEW_TOOLCHAIN system should read the
420: BUILDING document for caveats. Generally, BUILDING supersedes
421: UPDATING for these systems, as tool updating is taken care of
422: by the new build system.
1.42 perry 423:
424: 20011028:
425: src/etc/Makefile now needs install to be able to handle
426: symlinks that point to nowhere. A bug in install that
427: prevented this was corrected.
428:
429: Solution: update and reinstall usr.bin/xinstall
430: Better Solution: Use the new toolchain and it will just work
431: for you.
1.40 lukem 432:
433: 20011006:
434: /etc/mtree/NetBSD.dist has been updated to take advantage of
435: absolute path support added to mtree(8). Older mtree(8)s don't
436: understand the format.
437:
438: Solution: update and reinstall usr.sbin/mtree
1.39 jmc 439:
440: 20011004:
441: Crunchgen has been updated to work via reach-over makefiles. Updating
442: is suggested before running a snapshot build
1.36 tv 443:
1.35 thorpej 444: 20010915:
445: The new "ubcperf" code committed by Chuck Silvers removed
446: a header file, uvm/uvm_vnode.h. There may be stale .depend
447: files that still reference this file.
448:
449: Solution: "make cleandir && make dependall" in affected
450: directories.
1.31 enami 451:

453: grep.info is now built from grep.texi using makeinfo. Since it
454: requires makeinfo v4.0, you need to install new texinfo before
455: building gnu/usr.bin/grep. To install new texinfo, please follow
456: the instruction described in 20010726 entry.

1.64 sommerfe 458: 20010803:
1.41 wiz 459: (i386 only): i386 kernel now uses new instructions like
1.111 simonb 460: `fxsave' which old gas doesn't understand. To build the
1.64 sommerfe 461: kernel successfully, you need to build and install a new toolchain,
462: (i.e., build.sh -t) or (temporarily) comment out "options I686_CPU"
463: from your kernel configuration until you rebuild your userland.
464: See 20011029 above and BUILDING file in this directory for more information.
465: [updated 20020630 since i386 gas moved when USE_NEW_TOOLCHAIN enabled]
1.29 bjh21 466:
467: 20010731:
468: Bootloader update on ELF platforms. DDB in kernels from before
469: this will be unable to read symbol tables provided by newer
470: bootloaders.

473: Texinfo was updated to 4.0. To avoid failures when trying to
1.28 assar 474: build the included texinfo files, do:
475:
476: cd src/gnu/usr.bin/texinfo
477: make MKINFO=no dependall install
1.25 thorpej 478:
479: 20010718:
480: Enabled correct .init/.fini processing in crt0. The way this
481: was done was to change a -I directive to cc(1), which means
482: make(1) will have a stale dependency (it will be checking the
483: timestamp on the wrong "dot_init.h").
484:
485: The symptom you will see is that new programs die with SIGSEGV
486: if you have a stale dependency.
487:
488: Solution: "make cleandir" in both lib/csu and libexec/ld.elf_so
489: before starting your build.
1.26 thorpej 490:
491: 20010628:
492: A construct was added to uvm_page.h that uncovered a bug
493: in lint(1). If you get a warning/error about a non-portable
494: bitfield, update your lint(1) before proceeding.
1.21 jmc 495:

1.52 wiz 513: get/setprogname() added. Any hostprogs that may use this will need
1.111 simonb 514: to be bootstrapped manually until the host system is current.
1.18 jmc 515:
1.111 simonb 516: Known problems: sys/arch/macppc/stand/fixcoff

525: needs to be installed before make build.
1.10 christos 526:
527: 20010114:

1.23 tron 530: anything make and install in usr.bin/make, then proceed
1.10 christos 531: with make build.

1.8 sommerfe 536:

538: New share/mk files needed to support .WAIT in SUBDIR variables.
539: If you get make errors,
540: (cd share/mk; make install)
541: Also, PRINTOBJDIR has changed and is now used more heavily.

1.7 ad 544: The `ca' device driver has been replaced by `ld'; although the
1.6 ad 545: major and minor numbers haven't changed, you should update your /dev
546: directory.

549: The following make directives are obsoleted.
550: MKCRYPTO_RSA NOCRYPTO_RSA NOCRYPTO_RC5 NOCRYPTO_IDEA
551: By default, RSA is built into libcrypto. IDEA and RC5 will not be
1.16 wiz 552: built into libcrypto. By using MKCRYPTO_{RC5,IDEA}, you can build
1.4 itojun 553: additional library libcrypto_{idea,rc5}.
1.1 abs 554:
555:
556: Hints for a more successful build:
557: ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
1.2 mrg 558: Build a new kernel first:
559: This makes sure that any new system calls or features
560: expected by the new userland will be present. This
561: helps to avoid critical errors when upgrading.
1.1 abs 562: Use object directories:
563: This helps to keep stale object
564: files from polluting the build if a Makefile "forgets"
565: about one. It also makes it easier to clean up after
566: a build. It's also necessary if you want to use the
567: same source tree for multiple machines.
568: To use object directories:
569: a) cd /usr/src ; make cleandir
1.2 mrg 570: b) Add "OBJMACHINE=yes" to /etc/mk.conf
571: c) Add "MKOBJDIRS=yes" to /etc/mk.conf
1.1 abs 572: d) cd /usr/src ; make build
1.2 mrg 573: Note that running "make obj" in a directory will create
574: in obj.$MACHINE directory.
1.1 abs 575: Build to a DESTDIR:
576: This helps to keep old
577: installed files (especially libraries) from interfering
578: with the new build.
579: To build to a DESTDIR, set the DESTDIR environment
1.2 mrg 580: variable before running make build. It should be set to
581: the pathname of an initially empty directory.
1.1 abs 582: Problems: you might need to update critical utilities
583: without using DESTDIR since nothing is executed
584: from what is installed in DESTDIR.
585: (See critical utils, below)
586: Build often:
587: This keeps critical utilities current enough to not choke
588: on any other part of the source tree that depends on up to
589: date functionality.
590:
591: What to do if things don't work:
592: ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
593: When things don't work there is usually a few things that commonly
594: should be done.
595: 1) make includes
596: This should be done automatically by make build.
597: 2) cd share/mk && make install
598: Again, automatically done by make build.
599:
600: Failsafe rebuild of a small part of the tree:
601: ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
602: To make sure you rebuild something correctly you want to do
603: something like the following:
604: 1) Make sure the includes and .mk files are up to date.
605: 2) Make sure any program used to build the particular
606: utility is up to date. (yacc, lex, etc...)
607: 3) cd ...path/to/util...
608: make cleandir
609: rm ...all obj directories...
610: make cleandir # yes, again
611: make obj
612: make depend && make
613:
614: Failsafe rebuild of the entire tree:
615: ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
616: If you really want to make sure the source tree is clean and
1.2 mrg 617: ready for a build try the following. Note that sourcing /etc/mk.conf
618: (a make(1) Makefile) in this manner is not right, and will not work
619: for anyone who uses any make(1) features in /etc/mk.conf.
