5ea31d04dSWarner Losh
6ed478e7cSWarner Losh19990623:
7ed478e7cSWarner Losh	Compaq Smart Raid driver committed as ida.
8ed478e7cSWarner Losh
9075eeff2SWarner Losh19990622:
10075eeff2SWarner Losh	The second phase of syscons cleanup has happened.  Some
11075eeff2SWarner Losh	functionality has been made optional.  For details, see
12075eeff2SWarner Losh        http://www.freebsd.org/~yokota/sc_update-June.txt
136ae429caSWarner Losh	Everyone will need to re-config(8) their kernels, but old
146ae429caSWarner Losh	binaries will work with the new kernel.
15075eeff2SWarner Losh
16a883e9d3SWarner Losh19990620:
17a883e9d3SWarner Losh	IPFW uid/gid-based filtering support has been committed. This
18a883e9d3SWarner Losh	breaks binary compatibility with previous copies of
19a883e9d3SWarner Losh	ipfw(8). Any utilities using the ioctl()s of ipfw (especially
20a883e9d3SWarner Losh	ipfw(8)) need to be recompiled with the newest headers
21a883e9d3SWarner Losh	installed.
22a883e9d3SWarner Losh
23a883e9d3SWarner Losh19990618:
24a883e9d3SWarner Losh	Inetd now wraps all stream-based services, including internals.
25a883e9d3SWarner Losh	Syslog "severity" options are honoured. Installed syslog.conf
26a883e9d3SWarner Losh	and hosts.allow should be checked.
27a883e9d3SWarner Losh
2807b72539SWarner Losh19990509:
2907b72539SWarner Losh	Most of the problems with newbus have been corrected, but
3007b72539SWarner Losh	it is still current and evolving.
3107b72539SWarner Losh
3207b72539SWarner Losh	libcam's ABI has changed.  You must recompile the world and
3307b72539SWarner Losh	any ports that use it.
3407b72539SWarner Losh
3509fcf3f9SWarner Losh19990427:
3609fcf3f9SWarner Losh	Massive changes to SMP went into the tree that should speed
3709fcf3f9SWarner Losh	things up.  However, if you experience problems with SMP
3809fcf3f9SWarner Losh	machines, you can back off to the PRE_SMP_VMSHARE tag in the
3909fcf3f9SWarner Losh	CVS repository (or run an MP kernel).
4009fcf3f9SWarner Losh
4109fcf3f9SWarner Losh19990420:
4209fcf3f9SWarner Losh	Pccardd and the pccard bus in general seem to be broken or
4309fcf3f9SWarner Losh	most people.  Soren has patches to make it better for some,
4409fcf3f9SWarner Losh	but not all people.  Work is underway to make it better for
4509fcf3f9SWarner Losh	all people.
4609fcf3f9SWarner Losh
47ea31d04dSWarner Losh19990416:
48ea31d04dSWarner Losh	new bus changes integrated into -current.  Many problems were
49ea31d04dSWarner Losh	initially reported, but most have been fixed.  You'll need a
50ea31d04dSWarner Losh	new config and to tweak your kernel config file the way that
51ea31d04dSWarner Losh	GENERIC was tweaked.  Keep a copy of your old kernel when
52ea31d04dSWarner Losh	upgrading in case your new kernel doesn't work (and report the
53ea31d04dSWarner Losh	breakage to current@freebsd.org).
54ea31d04dSWarner Losh
55ea31d04dSWarner Losh	As of 19990421 the remaining problems/quirks are
56ea31d04dSWarner Losh
57ea31d04dSWarner Losh	o sio no longer supports pnp nor pccard.  This will be corrected,
58ea31d04dSWarner Losh	  but the new pccard code needs to be completed.
59ea31d04dSWarner Losh	o Some of the sound drivers broke for some people.  It seems
60ea31d04dSWarner Losh	  inconsistant as to who/what/when/where things broke.
61ea31d04dSWarner Losh	o Duplicate device entries in your config do not work.  Previously
62ea31d04dSWarner Losh	  they were silently ignored.  psm0 seems to be the most common
63ea31d04dSWarner Losh	  duplicate choice, although some reports have come in from people
64ea31d04dSWarner Losh	  that wired their scsi disk entries.
65ea31d04dSWarner Losh	o You must move the keyboard and mouse attachments from the
66ea31d04dSWarner Losh	  isa bus to the atkbdc bus.  See GENERIC for details.
67ea31d04dSWarner Losh	o Machines with multiple host-pci bridges (Intel 450NX) will not
68ea31d04dSWarner Losh	  probe the second pci bus.
69ea31d04dSWarner Losh	o Some probe ordering may have changed, so device naming may change
70ea31d04dSWarner Losh	  with the new kernel.  If you have multiple devices, please double
71ea31d04dSWarner Losh	  check to make sure they didn't move.  This is especially true
72ea31d04dSWarner Losh	  for cards on different buses.
73ea31d04dSWarner Losh	o The bus attachment for vga0 is always isa0 and never pci0 when
74ea31d04dSWarner Losh	  it is in fact a pci card.  It is safe to ignore this.
75ea31d04dSWarner Losh	o The format of the boot messages has changed (and is not
76ea31d04dSWarner Losh	  guaranteed to be constant for a while) so you may see this
77ea31d04dSWarner Losh	  in some shell scripts that diff dmesg from day to day as well
78ea31d04dSWarner Losh	  as scripts that parse dmesg output.
79f8c77507SWarner Losh
80d24adca8SWarner Losh19990414:
81d24adca8SWarner Losh	cc -aout sometimes has problems compiling with -g, remove -g
82d24adca8SWarner Losh	from those compilation units affected until this is corrected.
83d24adca8SWarner Losh
84d24adca8SWarner Losh	cc -aout has problems with producing some threaded libraries,
85d24adca8SWarner Losh	so make world -DWANT_AOUT is not functional at this time.
86d24adca8SWarner Losh
87ea31d04dSWarner Losh	Since make world for a.out isn't functional, you cannot do
88ea31d04dSWarner Losh	make aout-to-elf from a pre-egcs a.out system.  To work around
89ea31d04dSWarner Losh	this problem, make aout-to-elf using 3.1-stable first (or a
90ea31d04dSWarner Losh	pre egcs -current) and then a simple make world will take you
91ea31d04dSWarner Losh	the rest of the way with a -current source base.
92ea31d04dSWarner Losh
93d5ca0636SWarner Losh19990413:
94d24adca8SWarner Losh	Make -j works again for make world.  As always, use it with
95d24adca8SWarner Losh	care, and be sure to try a make world w/o -j before reporting
96d24adca8SWarner Losh	problems (that is, know if the problem exists w/o -j before
97d24adca8SWarner Losh	reporting the problem with -j).
98d24adca8SWarner Losh
99d24adca8SWarner Losh19990413:
100d24adca8SWarner Losh	Note cc -aout, which had been broken since the conversion to
101ea31d04dSWarner Losh	egcs, now supposedly works.  If you have rebuilt things like
102d24adca8SWarner Losh	XFree86 a.out libraries, you should rebuild them again or
103ea31d04dSWarner Losh	progams that use them, including netscape, will fail to work.
104d5ca0636SWarner Losh
1051f692d40SWarner Losh19990409:
1061f692d40SWarner Losh	NOTE: New c++ compiler cannot be used with c++ binaries from
1071f692d40SWarner Losh	the old compiler and vice versa.
1081f692d40SWarner Losh
1091f692d40SWarner Losh19990408:
11081725689SWarner Losh	In recent days egcs has been imported into the tree.  A number
11181725689SWarner Losh	of problems have been discussed in -current.  Here is a highlight
11281725689SWarner Losh	of a few of the more common ones.  With the exception of make
11381725689SWarner Losh	-j n, they have been claimed to have been fixed.
11481725689SWarner Losh
11581725689SWarner Losh	c++ is broken after make world: This is correct.  Because we
11681725689SWarner Losh	changed compilers two make worlds are necessary to get C++
11781725689SWarner Losh	working again.  The code generated by the old compiler and new
11881725689SWarner Losh	compiler are not compatible, so things wind up being
11981725689SWarner Losh	undefined.
12081725689SWarner Losh
12181725689SWarner Losh	cpp is broken in make world:  There was a window where cpp
12281725689SWarner Losh	would be built incorrectly.  The fix for this is
123420d4744SMasafumi Max NAKANE		cd src/gnu/usr.bin/cc
12481725689SWarner Losh		make clean
12581725689SWarner Losh		make all
12681725689SWarner Losh		make install
12781725689SWarner Losh	and this should correct your problems.  See the -current
12881725689SWarner Losh	archives for a version of this that does moer cleaning.
12981725689SWarner Losh
13081725689SWarner Losh	Make -j n doesn't work.  Work contiunes to make this work,
13181725689SWarner Losh	I've seen no reports of success as of April 7th.
13281725689SWarner Losh
133ff5e1f79SWarner Losh19990329:
134ff5e1f79SWarner Losh	Previously, one would define "NOAOUT" to keep from building
135ff5e1f79SWarner Losh	the legacy a.out bits.  Now one would define "WANT_AOUT" to
136ff5e1f79SWarner Losh	build them.
137ff5e1f79SWarner Losh
138fe9af953SWarner Losh19990316:
139fe9af953SWarner Losh	The name of the old wd.c and atapi.c based CDROM driver has
140fe9af953SWarner Losh	been changed back to wcd. So update your config file to use
141fe9af953SWarner Losh	"device wcd" instead of "device acd".
142fe9af953SWarner Losh
143fe9af953SWarner Losh19990314:
144fe9af953SWarner Losh	For those of you using the VN device as a loadable module,
145fe9af953SWarner Losh	please be aware that the new VN device has been committed to
146fe9af953SWarner Losh	-4.x and cannot yet be used as a loadable module.  This will
147fe9af953SWarner Losh	be fixed in the future.
148fe9af953SWarner Losh
149ce32355fSWarner Losh19990309:
150fe9af953SWarner Losh	New loader.rc mechanism.  Please see src/sys/boot/README for
151fe9af953SWarner Losh	details.
152ce32355fSWarner Losh
153f8c77507SWarner Losh19990225:
154f8c77507SWarner Losh	struct proc size changed.  Recompile kernel and the
155f8c77507SWarner Losh	usual suspects.  Make world if in doubt.
1561fc1a0dcSWarner Losh
1570edeb9e7SWarner Losh19990214:
1580edeb9e7SWarner Losh	The nlpt driver has changed names back to be the lpt driver.
1597dd38e55SWarner Losh	See ppbus(4) or http://www.freebsd.org/~nsouch/ppbus.html
1607dd38e55SWarner Losh	for proper configuration details.
1610edeb9e7SWarner Losh
1621fc1a0dcSWarner Losh19990210:
1631fc1a0dcSWarner Losh	The 'lpt' driver is now obsolete.  Replace it with the 'nlpt'
1640edeb9e7SWarner Losh	driver and 'ppbus' controller combination.
16557199806SWarner Losh
1667dd38e55SWarner Losh19990209:
1677dd38e55SWarner Losh	New devstat API requires recompilation of libdevstat, systat,
1687dd38e55SWarner Losh	iostat, vmstat and rpc.rstatd.  A new kernel is also required.
1697dd38e55SWarner Losh	make world + building a kernel should do all of this.  Any
1707dd38e55SWarner Losh	ports that use devstat need to be recompiled as well.
1717dd38e55SWarner Losh
1729a3105eeSWarner Losh19990125:
1739a3105eeSWarner Losh	Linux threads options has gone away (they are now standard in
1749a3105eeSWarner Losh	the FreeBSD kernel).  A recompile of all libkvm using programs
1759a3105eeSWarner Losh	is in order (or better yet a make world).
1769a3105eeSWarner Losh
1779a3105eeSWarner Losh19990122:
1789a3105eeSWarner Losh	On or about this date there was a small window when the boot
1799a3105eeSWarner Losh	blocks had some minor problems which seemed to force one to
1809a3105eeSWarner Losh	edit /etc/fstab.  This has been corrected, if you are seeing this
1819a3105eeSWarner Losh	problem, please rebuild and reinstall your boot blocks.
1829a3105eeSWarner Losh
1839a3105eeSWarner Losh19990121:
1848cd37f69SWarner Losh	Vinum has changed.  The "vinum read" command has changed.  For
1858cd37f69SWarner Losh	updates, please see
1863652181cSWarner Losh
1878cd37f69SWarner Loshhttp://www.freebsd.org/cgi/getmsg.cgi?fetch=800363+0+current/freebsd-current
1883652181cSWarner Losh
1898cd37f69SWarner Losh	for details.
1908cd37f69SWarner Losh
1918cd37f69SWarner Losh	Matt Dillon committed a boatload of VM changes, for
1928cd37f69SWarner Losh	information please see
1933652181cSWarner Losh
1948cd37f69SWarner Loshhttp://www.freebsd.org/cgi/getmsg.cgi?fetch=886676+0+current/freebsd-current
1958cd37f69SWarner Losh	or
1968cd37f69SWarner Loshhttp://www.freebsd.org/cgi/getmsg.cgi?fetch=827400+0+current/freebsd-current
1973652181cSWarner Losh
1988cd37f69SWarner Losh	for details.  These changes will likely not impact anybody,
1998cd37f69SWarner Losh	but large chagnes to the VM need at least a heads up.
2008cd37f69SWarner Losh
2018cd37f69SWarner Losh19990120:
2028cd37f69SWarner Losh	Stable branch created.  You might want to consider using this
2038cd37f69SWarner Losh	branch.  It is tagged with RELENG_3.
2048cd37f69SWarner Losh
205ad56ea87SWarner Losh19990119:
206ad56ea87SWarner Losh	More work on the syscons driver has been committed.  Since
207ad56ea87SWarner Losh	files moved around, you will need to reconfigure your kernel,
208ad56ea87SWarner Losh	and make clean; make depend before rebuilding the kernel.  No
209ad56ea87SWarner Losh	config file changes are needed.
210ad56ea87SWarner Losh
21157199806SWarner Losh19990111:
212a85c0f55SWarner Losh	New keyboard and video card drivers are introduced as the first
213a85c0f55SWarner Losh	stage of console driver reorganization.  You are required to
214a85c0f55SWarner Losh	update the kernel configuration file and rebuild the kernel.
215a85c0f55SWarner Losh	kbdcontrol, vidcontrol, and screen savers also need recompilation.
216a85c0f55SWarner Losh	The instruction can be found in
21757199806SWarner Losh
2187dafbc29SWarner Losh		http://www.freebsd.org/~yokota/sc_update.txt
21957199806SWarner Losh
220a85c0f55SWarner Losh	It has notes on splash screen too.
22157199806SWarner Losh
22257199806SWarner Losh19990106:
2239857e582SWarner Losh	Robert Nordier was kind enough to make this page to enable people to
224db23c94fSWarner Losh	install the new bootblocks:
22557199806SWarner Losh
2267dafbc29SWarner Losh		http://www.freebsd.org/~rnordier/boot.txt
22757199806SWarner Losh
2289ba54ae0SWarner Losh	When updating to ELF, make sure that you have updated your
2299ba54ae0SWarner Losh	/etc/rc files which have different ldconfig invocations for
2309ba54ae0SWarner Losh	elf and aout.  Otherwise things like X will stop working with
2319857e582SWarner Losh	messages about being unable to find library files.  The
2329857e582SWarner Losh	mergemaster utility in ports/sysutils/mergemaster helps to
2339857e582SWarner Losh	keep critical files like this in sync, and its use is
2349857e582SWarner Losh	recommended.
23557199806SWarner Losh
23657199806SWarner Losh19990104:
2372c558794SWarner Losh	Information about ELF day (see 19981230) can be found in
23857199806SWarner Losh
2397dafbc29SWarner Losh		http://www.freebsd.org/~peter/elfday.html
24057199806SWarner Losh
2412c558794SWarner Losh	about the upcoming change, its motivations and instructions
2422c558794SWarner Losh	for doing the upgrade.
24357199806SWarner Losh
24457199806SWarner Losh19981230:
245d5513f53SWarner Losh	You should install new bootblocks now.  The ELF kernel will
246e363c17bSWarner Losh	become default soon.  In addition, you'll need to upgrade
247e363c17bSWarner Losh	your userland programs to ELF before then as well.  Use
248e363c17bSWarner Losh	make aout-to-elf to upgrade your userland programs (old
249e363c17bSWarner Losh	a.out programs in, for example, /usr/local/bin will
250e363c17bSWarner Losh	continue to work, even after the upgrade).  See src/Makefile
251e363c17bSWarner Losh	for more details.
25257199806SWarner Losh
25357199806SWarner Losh19981224:
254355edc3eSWarner Losh	The old wcd driver has been deleted from the kernel.  The
255355edc3eSWarner Losh	driver that replaces it is named acd.  You'll need to change
256355edc3eSWarner Losh	this in your configuration files.
25757199806SWarner Losh
258355edc3eSWarner Losh	Failure to do this will result in "ATAPI CD-ROMs not
259355edc3eSWarner Losh	configured" at boot time.
26057199806SWarner Losh
261355edc3eSWarner Losh	The floppy tape driver (ft) has been removed from the kernel,
262355edc3eSWarner Losh	with no replacement driver.
26357199806SWarner Losh
26457199806SWarner Losh19981202:
265ab308df6SWarner Losh	New groups from 19981201 commented out of mtree, so they
266ab308df6SWarner Losh	aren't strictly needed, but still a good idea to have.
26757199806SWarner Losh
26857199806SWarner Losh19981201:
269ab308df6SWarner Losh	New user/group added: bind.  From src/etc/master.passwd and

27757199806SWarner Losh
27857199806SWarner Losh19981118:
27953dfde79SWarner Losh	PAM integrated into the tree.   Requires new /etc/pam.conf file
28053dfde79SWarner Losh	to silence warnings from authentication programs (login, etc).
