Updating Information for MidnightBSD users

Items affecting the mports and packages system can be found in
/usr/mports/UPDATING. 

20070814:
        Removed GNU tar source.  We've been using BSD tar 
        for awhile.

20070806:
        Finished removing umapfs and autofs from the tree.

20070804:
        BIND and Tcpdump have been patched for recent vulnerabilities.

        We switched to BSD cpio (pax).

20070719:
        Imported cpdup from DragonFly as /bin/cpdup

20070716:
        Update GNU cpio to 2.8. 

20070410:
        cvs was updated to 1.12.13.  cvsbug was removed.
        cvs now behaves similarly to DragonFly's cvs with
        most of their local changes.  

20070409:
        RELENG_0_1 was created. More aggresive changes will
        continue here.

20070406:
        Back out propolice.  propolice caused several problems
        with our threading libraries libthr and libpthread.  
        curthread was often NULL after the patch and many
        multithreaded applications would crash.  We plan to 
        work on either bringing in gcc 4.1 or developing a new
        patch which also corrects our threading issues later.

        It is more important to have a stable system for our
        mport work and other projects at this time.

        This is not a clean removal.  It is recommended that you
        have a recently SNAP CD handy.  You can either reinstall
        or perform a make buildworld and make buildkernel and 
        make installkernel.  Reboot on the cd and copy the contents
        of /bin, /sbin, /lib, /libexec, and /usr/bin, /usr/sbin,
        /usr/lib, and /usr/libexec to the respective directories on
        your disk.  Then you should be able to boot into single user
        mode and run make installworld.  You will need to run
        chflags noschg on some of the files if you can't overwrite
        them. 

        You will get __guard missing errors since we had to remove
        this from libc.

        You will need to rebuild any ports built while propolice was
        installed.

20070401:
        Importing propolice into MidnightBSD. Propolice is going to
        provide us with much greater security and stability in the
        long run. If upgrading from a pre-propolice system, please
        follow the these instructions:

        cd /usr/src/lib/libc && make obj && make && make install
        cd /usr/src/gnu/usr.bin/cc && make obj && make && make install
        cd /usr/src/lib/libpthread && make obj && make && make install
        cd /usr/src/lib/libthr && make obj && make && make install
        buildworld and kernel

        It is adviced that any mports which were installed and/or built
        prior to the propolice update also be updated. If any errors
        or issue are encounted, please contact security@midnightbsd.org
        and we will be sure to investigate and come up with an expeditious
        fix.

20070314:
        Remove send-pr from src.

        Switch to NetBSD's gzip.

        Bump MBSD minor revision.

20070313:
        Imported OpenSSH 4.6p1.

        Imported FreeBSD's libarchive and updated tar to work with it.

        Disabled debug statements cluttering up /var/log/messages for
        the tcp autobuf patch applied previously.

20070312:
        Synced several audio changes from FreeBSD 6.1. Removed the 
        BSD Daemon files from src/share.  

20070308:
        Added mfi which supports LSI Logic MegaRAID SAS devices including
        the Dell perc5i.

20070206:
        Imported OpenBSD's sudo into source. Please install
        /usr/src/usr.bin/sudo/lib first before building.

        Those who install from a snapshot after this date
        will not be effected.

20070119:
        Added audit group.  Be sure to add audit to your /etc/group file
        before installing world.

        hostapd was updated to 0.4.8.

        An accidental commit in usr.sbin/bluetooth/hccontrol was fixed to
        unbreak world.

        wpa_supplicant was updated.

        For stability and compatibility reasons, it was decided that MidnightBSD
        sync with FreeBSD 6.1 Release.  Nearly every change between the original
        fork date of February 24, 2006 and the release of FreeBSD 6.1 in May
        2006 will be merged.  Beyond this, MidnightBSD will be a "real" fork and
        will not sync every little change with FreeBSD.

20061231:
        Updated COPYRIGHT for 2007.

        Updated and bumped libutil after importing NetBSD efun(3) functions.

        Added MidnightBSD_version and bumped the FreeBSD version as we've
        synced all commits between the fork and that version.  It is now safe
        to assume MidnightBSD is compatible with FreeBSD RELENG_6 from
        Feb 26, 2006.

        Added spell(1) and deroff(1) from NetBSD.  Also added additional
        dict files to work with it. /usr/share/dict/american, 
        /usr/share/dict/british and /usr/share/dict/special/math

        Numerous man page and bug fixes.

20061226:
        Setup /usr/share/examples/cvsup SUPfiles for the new
        MidnightBSD CVSup server. 

        Fix a bug in burncd where it would continue forever while
        erasing CDRW media.

        Add csup to /usr/bin.  csup is a CVSup replacement written
        in C. 

        Fixed a bug with bsnmpd build from Oct 30.  

        Corrected some race conditions and fixed a few bugs in
        geom.  Imported changes from FreeBSD RELENG_6.

20061225:
        Fixed a typo in src/lib/libc/sparc64/fpu/fpu_implode.c
        that caused long double to long and long long 
        conversion of negative numbers to always result in -1.

20061221:
        Fixed acpi_battery.c to not report an ERROR if no
        batteries are present.

        Performed some minor updates on the RL and RE NIC drivers.
        RL should no longer panic when trying to print errors.

        Corrected a bug with TTY.

20061218:
        Corrected a bug with libpthread where newly created suspended
        threads don't get scheduled.

20061206:
        Fixed a typo with the firewire security patch.

20061129:
        Minor cleanups to utilities in bin.

        Fixed msdos file system short file name behavior to match
        FreeBSD.

20061031:
        Updated man pages in section 7.

20061030:
        Updated sys/dev/drm to support intel 915 and radeon 
        r300 cards properly.  

        Synced snmpd with FreeBSD-stable.

        Fixed a bug in rm which could cause data loss.  

20061027:
        Added Intel ICH8 and nForce 5 support to ATA. cam, mpt,
        random, kbdmux, atkbd, and usb were updated.  Changes
        to clearing registers on SSE enabled processors (i386)
        commited.  

        lukemftpd updated.  

        openssh rc script was altered which effects initial
        seeding.  

20061014:
        Workaround for em driver problem on shared IRQ.

        Started removal of alpha support.

20061013:
        ATA driver was updated.  USB/USB1/USB2 types added.

20061010: 
        OpenSSH was updated to 4.4p1.   

20060909:
        OpenNTPD was added to MidnightBSD.  Run make delete-old to remove
        the old ntpd daemon.

        cat has a new option -D which allows you to timestamp output
        on a per line basis.

        The kernel has a keyboard mux which allows you to have multiple
        keyboard connected simultaneously.  USB keyboard support was also
        improved with this patch.

        The Intel em driver was updated.  Network performance was greatly
        increased on many systems.  Additional models are supported.

        The ATA driver was patched to fix a potential deadlock.

        Bind was patched to fix a potential denial of service condition.

20060817:
        ksh has been added to the base system.  If you previously had
        the port installed, it will be overwritten on the next buildworld.


        To build a kernel
        -----------------
        If you are updating from a prior version of MidnightBSD (even one just
        a few days old), you should follow this procedure. With a
        /usr/obj tree with a fresh buildworld,
        make -DALWAYS_CHECK_MAKE buildkernel KERNCONF=YOUR_KERNEL_HERE
        make -DALWAYS_CHECK_MAKE installkernel KERNCONF=YOUR_KERNEL_HERE

        To test a kernel once
        ---------------------
        If you just want to boot a kernel once (because you are not sure
        if it works, or if you want to boot a known bad kernel to provide
        debugging information) run
        make installkernel KERNCONF=YOUR_KERNEL_HERE KODIR=/boot/testkernel
        nextboot -k testkernel

        To just build a kernel when you know that it won't mess you up
        --------------------------------------------------------------
        This assumes you are already running a 6.X system.  Replace
        ${arch} with the architecture of your machine (e.g. "i386",
        "amd64", "ia64", "pc98", "sparc64", etc).

        cd src/sys/${arch}/conf
        config KERNEL_NAME_HERE
        cd ../compile/KERNEL_NAME_HERE
        make depend
        make
        make install

        If this fails, go to the "To build a kernel" section.

        To rebuild everything and install it on the current system.
        -----------------------------------------------------------
        # Note: sometimes if you are running current you gotta do more than
        # is listed here if you are upgrading from a really old current.

        <make sure you have good level 0 dumps>
        make buildworld
        make kernel KERNCONF=YOUR_KERNEL_HERE
                                                        [1]
        <reboot in single user>                         [3]
        mergemaster -p                                  [5]
        make installworld
        make delete-old
        mergemaster                                     [4]
        <reboot>


        To cross-install current onto a separate partition
        --------------------------------------------------
        # In this approach we use a separate partition to hold
        # current's root, 'usr', and 'var' directories.   A partition
        # holding "/", "/usr" and "/var" should be about 2GB in
        # size.

        <make sure you have good level 0 dumps>
        <boot into -stable>
        make buildworld
        make buildkernel KERNCONF=YOUR_KERNEL_HERE
        <maybe newfs current's root partition>
        <mount current's root partition on directory ${CURRENT_ROOT}>
        make installworld DESTDIR=${CURRENT_ROOT}
        cd src/etc; make distribution DESTDIR=${CURRENT_ROOT} # if newfs'd
        make installkernel KERNCONF=YOUR_KERNEL_HERE DESTDIR=${CURRENT_ROOT}
        cp /etc/fstab ${CURRENT_ROOT}/etc/fstab                    # if newfs'd
        <edit ${CURRENT_ROOT}/etc/fstab to mount "/" from the correct partition>
        <reboot into current>
        <do a "native" rebuild/install as described in the previous section>
        <maybe install compatibility libraries from src/lib/compat>
        <reboot>


        To upgrade in-place from 5.x-stable or higher to 6.x-stable
        -----------------------------------------------------------
        <make sure you have good level 0 dumps>
        make buildworld                                 [9]
        make kernel KERNCONF=YOUR_KERNEL_HERE           [8]
                                                        [1]
        <reboot in single user>                         [3]
        mergemaster -p                                  [5]
        make installworld
        make delete-old
        mergemaster -i                                  [4]
        <reboot>

        Make sure that you've read the UPDATING file to understand the
        tweaks to various things you need.  At this point in the life
        cycle of current, things change often and you are on your own
        to cope.  The defaults can also change, so please read ALL of
        the UPDATING entries.

        Also, if you are tracking -current, you must be subscribed to
        freebsd-current@freebsd.org.  Make sure that before you update
        your sources that you have read and understood all the recent
        messages there.  If in doubt, please track -stable which has
        much fewer pitfalls.

        [1] If you have third party modules, such as vmware, you
        should disable them at this point so they don't crash your
        system on reboot.

        [3] From the bootblocks, boot -s, and then do
                fsck -p
                mount -u /
                mount -a
                cd src
                adjkerntz -i            # if CMOS is wall time
        Also, when doing a major release upgrade, it is required that
        you boot into single user mode to do the installworld.

        [4] Note: This step is non-optional.  Failure to do this step
        can result in a significant reduction in the functionality of the
        system.  Attempting to do it by hand is not recommended and those
        that pursue this avenue should read this file carefully, as well
        as the archives of freebsd-current and freebsd-hackers mailing lists
        for potential gotchas.

        [5] Usually this step is a noop.  However, from time to time
        you may need to do this if you get unknown user in the following
        step.  It never hurts to do it all the time.

        [8] In order to have a kernel that can run the 5.x binaries
        needed to do an installworld, you must include the COMPAT_FREEBSD5
        option in your kernel.  Failure to do so may leave you with a system
        that is hard to boot to recover. A similar kernel option COMPAT_FREEBSD5
        is required to run the 5.x binaries on more recent kernels.

        Make sure that you merge any new devices from GENERIC since the
        last time you updated your kernel config file.

        [9] When checking out sources, you must include the -P flag to have
        cvs prune empty directories.

        If CPUTYPE is defined in your /etc/make.conf, make sure to use the
        "?=" instead of the "=" assignment operator, so that buildworld can
        override the CPUTYPE if it needs to.

        MAKEOBJDIRPREFIX must be defined in an environment variable, and
        not on the command line, or in /etc/make.conf.  buildworld will
        warn if it is improperly defined.

131	Added MidnightBSD_version and bumped the FreeBSD version as we've
132	synced all commits between the fork and that version. It is now safe
133	to assume MidnightBSD is compatible with FreeBSD RELENG_6 from
134	Feb 26, 2006.
135
136	Added spell(1) and deroff(1) from NetBSD. Also added additional
137	dict files to work with it. /usr/share/dict/american,
138	/usr/share/dict/british and /usr/share/dict/special/math
139
140	Numerous man page and bug fixes.
141
142	20061226:
143	Setup /usr/share/examples/cvsup SUPfiles for the new
144	MidnightBSD CVSup server.
145

149	Add csup to /usr/bin. csup is a CVSup replacement written
150	in C.
151
152	Fixed a bug with bsnmpd build from Oct 30.
153
154	Corrected some race conditions and fixed a few bugs in

159	that caused long double to long and long long
160	conversion of negative numbers to always result in -1.
161
162	20061221:
163	Fixed acpi_battery.c to not report an ERROR if no
164	batteries are present.
165
166	Performed some minor updates on the RL and RE NIC drivers.
167	RL should no longer panic when trying to print errors.
168
169	Corrected a bug with TTY.
170

194
195	20061027:
196	Added Intel ICH8 and nForce 5 support to ATA. cam, mpt,
197	random, kbdmux, atkbd, and usb were updated. Changes
198	to clearing registers on SSE enabled processors (i386)
199	commited.
200
201	lukemftpd updated.
202
203	openssh rc script was altered which effects initial
204	seeding.

220
221	cat has a new option -D which allows you to timestamp output
222	on a per line basis.
223
224	The kernel has a keyboard mux which allows you to have multiple
225	keyboard connected simultaneously. USB keyboard support was also
226	improved with this patch.
227
228	The Intel em driver was updated. Network performance was greatly
229	increased on many systems. Additional models are supported.

233	Bind was patched to fix a potential denial of service condition.
234
235	20060817:
236	ksh has been added to the base system. If you previously had
237	the port installed, it will be overwritten on the next buildworld.
238
239
240
241	To build a kernel
242	-----------------
243	If you are updating from a prior version of MidnightBSD (even one just
244	a few days old), you should follow this procedure. With a
245	/usr/obj tree with a fresh buildworld,
246	make -DALWAYS_CHECK_MAKE buildkernel KERNCONF=YOUR_KERNEL_HERE
247	make -DALWAYS_CHECK_MAKE installkernel KERNCONF=YOUR_KERNEL_HERE
248
249	To test a kernel once
250	---------------------
251	If you just want to boot a kernel once (because you are not sure
252	if it works, or if you want to boot a known bad kernel to provide
253	debugging information) run
254	make installkernel KERNCONF=YOUR_KERNEL_HERE KODIR=/boot/testkernel
255	nextboot -k testkernel
256
257	To just build a kernel when you know that it won't mess you up
258	--------------------------------------------------------------
259	This assumes you are already running a 6.X system. Replace
260	${arch} with the architecture of your machine (e.g. "i386",
261	"amd64", "ia64", "pc98", "sparc64", etc).
262
263	cd src/sys/${arch}/conf
264	config KERNEL_NAME_HERE
265	cd ../compile/KERNEL_NAME_HERE
266	make depend
267	make
268	make install
269
270	If this fails, go to the "To build a kernel" section.
271
272	To rebuild everything and install it on the current system.
273	-----------------------------------------------------------
274	# Note: sometimes if you are running current you gotta do more than
275	# is listed here if you are upgrading from a really old current.
276
277	<make sure you have good level 0 dumps>
278	make buildworld
279	make kernel KERNCONF=YOUR_KERNEL_HERE
280	[1]
281	<reboot in single user> [3]
282	mergemaster -p [5]
283	make installworld
284	make delete-old
285	mergemaster [4]
286	<reboot>
287
288
289	To cross-install current onto a separate partition
290	--------------------------------------------------
291	# In this approach we use a separate partition to hold
292	# current's root, 'usr', and 'var' directories. A partition
293	# holding "/", "/usr" and "/var" should be about 2GB in
294	# size.
295
296	<make sure you have good level 0 dumps>
297	<boot into -stable>
298	make buildworld
299	make buildkernel KERNCONF=YOUR_KERNEL_HERE
300	<maybe newfs current's root partition>
301	<mount current's root partition on directory ${CURRENT_ROOT}>
302	make installworld DESTDIR=${CURRENT_ROOT}
303	cd src/etc; make distribution DESTDIR=${CURRENT_ROOT} # if newfs'd
304	make installkernel KERNCONF=YOUR_KERNEL_HERE DESTDIR=${CURRENT_ROOT}
305	cp /etc/fstab ${CURRENT_ROOT}/etc/fstab # if newfs'd
306	<edit ${CURRENT_ROOT}/etc/fstab to mount "/" from the correct partition>
307	<reboot into current>
308	<do a "native" rebuild/install as described in the previous section>
309	<maybe install compatibility libraries from src/lib/compat>
310	<reboot>
311
312
313	To upgrade in-place from 5.x-stable or higher to 6.x-stable
314	-----------------------------------------------------------
315	<make sure you have good level 0 dumps>
316	make buildworld [9]
317	make kernel KERNCONF=YOUR_KERNEL_HERE [8]
318	[1]
319	<reboot in single user> [3]
320	mergemaster -p [5]
321	make installworld
322	make delete-old
323	mergemaster -i [4]
324	<reboot>
325
326	Make sure that you've read the UPDATING file to understand the
327	tweaks to various things you need. At this point in the life
328	cycle of current, things change often and you are on your own
329	to cope. The defaults can also change, so please read ALL of
330	the UPDATING entries.
331
332	Also, if you are tracking -current, you must be subscribed to
333	freebsd-current@freebsd.org. Make sure that before you update
334	your sources that you have read and understood all the recent
335	messages there. If in doubt, please track -stable which has
336	much fewer pitfalls.
337
338	[1] If you have third party modules, such as vmware, you
339	should disable them at this point so they don't crash your
340	system on reboot.
341
342	[3] From the bootblocks, boot -s, and then do
343	fsck -p
344	mount -u /
345	mount -a
346	cd src
347	adjkerntz -i # if CMOS is wall time
348	Also, when doing a major release upgrade, it is required that
349	you boot into single user mode to do the installworld.
350
351	[4] Note: This step is non-optional. Failure to do this step
352	can result in a significant reduction in the functionality of the
353	system. Attempting to do it by hand is not recommended and those
354	that pursue this avenue should read this file carefully, as well
355	as the archives of freebsd-current and freebsd-hackers mailing lists
356	for potential gotchas.
357
358	[5] Usually this step is a noop. However, from time to time
359	you may need to do this if you get unknown user in the following
360	step. It never hurts to do it all the time.
361
362	[8] In order to have a kernel that can run the 5.x binaries
363	needed to do an installworld, you must include the COMPAT_FREEBSD5
364	option in your kernel. Failure to do so may leave you with a system
365	that is hard to boot to recover. A similar kernel option COMPAT_FREEBSD5
366	is required to run the 5.x binaries on more recent kernels.
367
368	Make sure that you merge any new devices from GENERIC since the
369	last time you updated your kernel config file.
370
371	[9] When checking out sources, you must include the -P flag to have
372	cvs prune empty directories.
373
374	If CPUTYPE is defined in your /etc/make.conf, make sure to use the
375	"?=" instead of the "=" assignment operator, so that buildworld can
376	override the CPUTYPE if it needs to.
377
378	MAKEOBJDIRPREFIX must be defined in an environment variable, and
379	not on the command line, or in /etc/make.conf. buildworld will
380	warn if it is improperly defined.
