30 New to release 0.4.5 (LKS version 4.9 release1)
31 ======================================
33 * This release is based on the third beta release of
34 PPP-2.2 (ppp-2.2b3.tar.gz) by Paul Mackerras. It will
35 probably be the version released along with PPP-2.2.
37 * Some enhancements to the Example ip-up and ip-down
40 * Several documentation enhancements to support the
43 * Removed the new locking code. Temporarily, we continue
44 to rely on the old mechanism.
46 * This program runs on Intel, Moto, and Sparc. It apparently
47 runs fine on HP until shutdown. Then there appear to be problems.
48 Due to time constraints, this will have to be corrected as a patch.
49 As usual, this will be available on ftp.thoughtport.com:/pub/next/ppp/.
52 New to release 0.4.4 (LKS version 4.5)
53 ======================================
55 * The netbuf queueing mechanism was significantly
56 simplified. It is hoped that some HP memory
57 alignment problems were also solved. This may
58 help solve some of the mysterious panics others have
61 * A new locking mechanism was implemented that
62 may simplify the spl() calls.
64 * Memory allocation in BSD Compress code was cleaned up in
65 an attempt to solve HP alignment problems.
67 * Thanks go to Pete French <pete@ohm.york.ac.uk> for all the
70 New to release 0.4.3 (LKS version 4.4)
71 ======================================
73 * This release fixes some problems regarding
74 HP and SPARC support. It is said to now run
75 on Sparc. I would hope HP also but havn't heard
76 yet. Thanks to Dave Hess <David-Hess@net.tamu.edu>
77 for finding the problems for Sparc.
79 * Minor documentation fixes.
82 New to release 0.4.0 (LKS version 4.1 - summerb2)
83 =================================================
85 * This release is based on the second beta release
86 of PPP-2.2 (ppp-2.2b2).
88 * The default chat is now the one supplied in the beta
89 PPP release. This chat will compile fine using Dev 3.3.
90 However, if you are running Dev 3.2, you will not be able
91 to compile the default chat (POSIX problems). In this case,
92 you may use the old chat (renamed as ./chat/chat.c.3.2).
96 New to release 0.4.0 (LKS version 4.0 - summerb1)
97 =================================================
99 * This release is based on the first beta release
100 of PPP-2.2 (ppp-2.2b1).
102 * Chat was updated in the new beta. However, because
103 of broken posix functionality under NeXTSTEP (3.2) it
104 will not compile properly. Therefore, the old chat
105 is being used. The newer chat is backed up as
106 ./chat/chat.c.orig. Those with Dev 3.3 may wish to
107 try to compile to see if the posix problems were fixed.
109 * Support for the Microsoft Call Back Configuration Protocol.
110 See the file ./README.cbcp.
114 New to release 0.3.0 (LKS version 3.0 - summera51)
115 =====================================
117 * This release is the first to be based on the fifth alpha
118 release of PPP-2.2 (ppp-2.2a5).
120 * Major kernel revision. This release attempts to merge
121 the LKS written by Perkins and that written by Prindeville/French.
122 The hope is that this new merged kernel will allow us to maintain
123 one set of sources. This kernel, or a variant thereof, will
124 probably be the one that is released with the PPP-2.2 beta
127 * Fixed a bug that caused problems with NXFax's capability
128 to determine port usage.
130 * Added support for the Berkley Packet Filter (BPF) and tcpdump.
131 Use of BPF requires special installation instructions. See
132 the installation file for more info.
134 * Fixed a header include problem that kept sources from compiling
135 under NS 3.3 Dev. for m68k. *Sigh* I guess support for m68k
136 continues to falter... :(
138 * Officially changed the name of the log file from:
139 /usr/adm/ppp2.2.debug
142 If you are upgrading, you should change the name of the file
143 in /etc/syslog.conf. Remember to watch out for the tab character
144 and remember to create the initial file. For more information see
147 This change was done so that the file could be opened from the
148 workspace. There was a naming conflict with the .debug extension.
149 Note also, that this name is a bit different than that suggested in
152 * Fixed a problem with the pppd option 'local'.
156 * Fixed a bug in pppd that would allow service (under some circumstances)
157 to peers who refuse to authenticate.
159 * Fixed a bug with CCP negotiation.
161 * Fixed a bug that caused negotation with an NT RAS PPP server to fail.
164 New to release 1.9 (LKS version 2.1)
165 =====================================
167 * Support for NS Sparc has been added. Sparc users note, the SUN
168 serial driver in the pre-release was not very robust at high speeds.
169 This has been fixed for the final release. This could cause problems
170 with testing on Sparc. Low bps rates should be OK...like 2400 to
171 maybe 9600 with low system activity. Thanks go to
172 John Landwehr <John_Landwehr@NeXT.COM> for this work.
174 * Fixed a nasty little bug that degraded performance of multiple
175 interfaces on Intel systems.
177 * Added support for IP address filtering. This allows
178 detection and prevetion of IP address spoofing. Check out
179 the new ./pppexclude directory. Thanks to
180 Lawrence E. Freil <lef@woods.com> for this code.
182 * More support for multiple ppp connections to different
183 hosts. Check out ./Examples/ppp_multiple_hosts.tar.gz.
184 Thanks to Jonathan Adams <jonathan@filoli.com> for this
187 * Modified lock file for better UUCP interaction. Special
188 thanks to Kim Shrier <kim@tinker.com> for this code.
190 * Fixed the new 3.3 multicast warning.
192 * Improved installation documentation.
195 New to release 1.8 (LKS version 1.3)
196 =====================================
198 * Moved to ppp-2.2a4, the fourth alpha release
199 from Paul Mackerras <Paul.Mackerras@cs.anu.edu.au>.
201 * Fixed a bug that I introduced in 1.7 that could cause
202 kernel panics when BSD compression was used in conjunction
203 with VJ header compression.
205 * LKS Numbering Scheme changed (due to my screwup with a4 and CVS).
207 * Removed support for extra pppd option 'usepty'. Can be done
208 with an external program if desired.
210 * Included the old modified pppstats.c that shows compression
213 New to release 1.7 (LKS version 1.31)
214 =====================================
216 * Moved packet compression outside the interrupt handler.
217 Previously, only packet decompression was done outside.
219 * Made many enhancements as suggested by Paul Mackerras.
221 * Fixed a bug that sometimes caused "bad fcs" errors to panic
224 * Fixed a problem that caused NFS traffic to force
225 compression to exit (and sometimes hang NFS).
226 NFS traffic works properly now (regardless of the buffer size
227 set via the NFSManager.app).
229 * Fixed a timeout problem in pppd that could sometimes cause
230 negotiations to loop endlessly. This fix should eventually make
233 * Split code into multiple files for better organization.
235 * Fixed pppstats to show compression ratios on the proper
236 side. Left side is for incoming packets and right side is
237 for outgoing packets.
239 * Added some suggested enhancements to
240 pppd. These suggestions were brought up
241 on the ports mailing list and will probably
242 be included in ppp2.2a4. I added them for
243 the interrim. They basically involve better permissions
244 for running the ip-up and ip-down scripts. They are now run
245 as the effective user-id of pppd. So if you run pppd suid,
246 root, then ip-up and ip-down are run as root.
248 * Corrected several minor documentation problems.
251 New to release 1.6 (LKS version 1.24)
252 =====================================
254 * Added support for HP-PA systems. Many thanks go to
255 Alain Fauconnet <af@biomath.jussieu.fr> for his efforts in this
258 * Added further performance enhancements to the LKS. This resulted
259 in fewer "silo overflows", and thus dropped packets, when operating
260 at high speed (>= 38.4KBS) sustained bidirectional transfers over
263 * Updated the installation instructions.
266 New to release 1.5 (LKS version 1.22)
267 =====================================
269 * Not a real release. Used for distributing
273 New to release 1.4 (LKS version 1.18)
274 =====================================
276 * Fixed problem that delayed many PPP protcol packets from timely
279 * Added compression statistics support for pppstats.
281 * Cleaned up processor priority levels.
283 * Added better support for netbuf queue monitoring.
286 New to release 1.3 (LKS version 1.16)
287 =====================================
289 * At compile time, you have the option to decompress VJ/BSD
290 packets either inside or outside the interrupt handler.
291 See the DECOMP_OUT flag in ./NeXT/Makefile. The old
292 functionality was to do the work inside the interrupt
293 handler. It is probably more appropriate to do it
294 outside. Thanks to Pete French <pete@ohm.york.ac.uk> for
295 discussion on this topic.
297 * Added initial support for operation over pseudo
298 ttys. See the USEPTY flag in ./pppd/Makefile.NeXT.
299 This adds a new option to pppd, "usepty <hostname>".
300 If this option is used, pppd will fire up an rlogin
301 session to <hostname>. You may then use chat as normal
302 to start the remote ppp. Thereafter, the packets flow
303 over the rlogin session. This may potentially be used
304 to start a new ppp session over an open ppp session.
306 * Added enhancements and changes suggested for ppp-2.2a3.
307 This includes some fixes to the BSD compression code
308 that caused it to turn off compression inappropriately
309 under error conditions.
311 * Patched pppd to better support code that sleeps but never
312 wakes in ip-up scripts. Thanks to longyear@netcom.com
313 (Al Longyear) and Bill Hay <wish@dumain.demon.co.uk>.
315 * Did more verification with the full version of NXFAX installed.
316 Seems to work flawlessly! Thanks to Rick Damon <nxfax@bandw.com>
317 at Black and White for his help in the matter.
319 * Added a new 'Examples' directory to the hierarchy. This
320 will become a collecting place for user info.
324 New to release 1.2 (LKS version 1.13)
325 =====================================
327 * The system now supports BSD Packet compression using the new CCP.
328 Of course, both ends must negotiate this option.
334 * The system now works with the MuX serial driver V1.5. Probably
335 version 1.4 also. No changes need to be made to the MuX buffer
336 (and DOUBLE_BUFFER) values.
338 * The system now works when NXFax is installed.
340 * There have been some internal optimizations for those
341 who use the NeXT supplied serial drivers.
347 * On Intel systems, some ioctl calls did not return the proper value.
348 This turned out to be a bug in the OS. A true workaround has been
349 implemented. The ioctl return value macro is now only used to
350 check for return value errors. Flags are now correctly set without
353 * Multiple interfaces now work properly. The ioctl fix above solved
354 the problem of a second interface "stealing" the first interface.
356 * lcp-echo-failure works.
358 * We are now using the default pppstats. This was modified to
359 use an ioctl to get information. One less program we have to
360 support. pppstats no longer requires the SUID bit or the loadable.
362 * We are now using the default VJ compression code. Another
363 file we do not have to support.
365 * PPP-2.2 uses a new mechanism for determining when to kill pppd.
366 This should solve the process group problems we have been
369 * Compression is not yet implemented. This release should give you
370 the same (but more stable) functionality as the ppp-2.1.2 release.
