[pups] A 2nd http mirror of the Unix Archive

by Warren Toomey

All, Oleg Safiullin has set up a Unix Archive mirror outside of Australia. You can find it at: http://unix-archive.pdp11.org.ru He is using the same username & password list as www.tuhs.org is. Thanks to Oleg for setting this up. Warren P.S I do have a number of other people interested in setting up other mirrors. When I get back from this week's conference, I'll contact you all.

[pups] BSD 2.11 SL/IP and sim2.3d+BB1

by PUP

I know that there must be some setup guides for BSD2.11 still floating around there, but I have not been able to find anything.. Here is what I am trying to do: I noticed that the sim2.3d+BB1 emulator will allow you to connect Unix "devices" to the DL1 lines. I set it to connect the serial port on my Linux box, and connected a IBM 3151 (VT100 like terminal), and it worked great! Taking this a step further, I took the serial port and moved it to my Cisco router (the aux port).. I have been trying to configure SL/IP on it.. I first setup my Linux box to connect to the router via slip so that I can verify my cisco config. I am having trouble on the BSD side.. As far as I can tell it is not routing replys over the sl0 interface.. (Or the emulator is cooking the serial data...) A final test I tried to connect to copies of sim2.3d+BB1 via pty's.. same thing. The good part is when you try to telnet from the router, you can see the socket accept on the BSD side.. The BSD box seems not to reply.. Additionally I saw some stuff on increasing the size of CBLOCK in param.h (my default was 32, I tried 64), which seemed to have no effect. I started SL/IP by running slattach ttyl1 9600 then ifconfig sl0 10.1.1.1 10.1.1.2 up by default as this I can't ping the 10.1.1.1 (my side).. so I added a route route add 10.1.1.1 127.0.0.1 0 I don't know if I have to do this... Oh the image that I'm using is the 2.11_rp_unknown from the archive.. (It has a note that it is patch level 400.) Also the person that maintains BSD 2.11's site is down.. bummer..

Here is what I /usr/doc/2.10/setup.2.11 bit of a misnomer and it's a long enough story I won't bother anyone with the details. That's the raw troff sources though. If it's the formatted version that is wanted there should be a copy in the 2.11 portion of the PUPS/TUHS section of the archive. It shows up at PDP-11/Distributions/ucb/2.11BSD and there are also complete tarballs and a dump of the root filesystem all at rev level 431. It should be a simple matter of putting the bits on tape/disk (using the makesimtape or similar utility provided with the emulator being used). At that point the normal 2.11 installation process can be followed - there have only been 5 updates since then (432 thru 436) so catching up wouldn't be hard at all. > I noticed that the sim2.3d+BB1 emulator will allow you to connect Unix > "devices" to the DL1 lines.

Probably doing 7E1 and just about anything would work with that ;) > Taking this a step further, I took the serial port and moved it to my Cisco > router (the aux port).. I have been trying to configure SL/IP on it.. That'll definitely require a 'raw' or 8bit clean path and I don't know if the sim2.3d does that or not - never tried it. The stock sim2.3d doesn't appear to have extra serial line support - or if it does it isn't obvious. Perhaps that is what the BB1 part is about. > I first setup my Linux box to connect to the router via slip so that I can > verify my cisco config. I am having trouble on the BSD side.. As far as I > can tell it is not routing replys over the sl0 interface.. (Or the emulator > is cooking the serial data...) That's a real possibility. The 'slattach' command on the 11 side will take care of setting all the modes so that an 8bit path is obtained. If the emulator is stripping the parity bit (which wouldn't show up in the normal "hook a terminal up" test) then SL/IP will obviously have problems. You might have better luck with the Begemot emulator P11. No need for SL/IP since P11 has an emulated DEQNA ethernet driver. > A final test I tried to connect to copies of sim2.3d+BB1 via pty's.. same > thing.

You shouldn't have to do that because in /etc/netstart, if things are set up right you would have: slattach ttyl1 9600 ifconfig sl0 10.1.1.1 10.1.1.2 up route add $hostname localhost 0 route add default $default 1 So if 'hostname' and 'default' are set at the top of the file all the routing is all set to go. Just make sure that 'ifconfig sl0' happens before 'ifconfig lo0 ...'. Also, by default the C library is compiled to use DNS resolver routines so it will likely be necessary to use a combination of numeric IP addresses and entries in /etc/hosts > Oh the image that I'm using is the 2.11_rp_unknown from the archive.. > (It has a note that it is patch level 400.) That is fairly old, but SL/IP hasn't changed since the system came out eons ago. > Also the person that maintains BSD 2.11's site is down.. bummer..

[pups] John Wilson / DBit offline

Hi all, In case you're trying to get a hold of John Wilson, or were going to look at his web site... no go. Due to a fairly serious ISP, uhh, "issue", his machine died on him. I talked to him last night, and he was going to see if he could revive his (co-lo) machine, or would have to install a new one.

[pups] Change of PUPS list address

by Warren Toomey

All, The machine which hosts the pups mailing list, minnie.cs.adfa.edu.au, is going to change its domain name in mid-July. To help alleviate any problems, I have taken out a separate domain, and have put in aliases to the current minnie address, and will migrate the aliases to the new address when the time comes. So, if possible could you send e-mail to the pups mailing list using the address pups(a)tuhs.org from now on. Thanks, Warren Toomey wkt(a)tuhs.org

Re: [pups] V6 and Supnik-simulator

by Wolfgang Helbig

Hi, Warren put the v6enb.tar.gz into http://minnie.cs.adfa.edu.au/TUHS/Archive/PDP-11/Bug_Fixes/V6enb/ Thank you, Warren! Besides some minor and rather unimportant changes to V6, this file contains README files, that try to explain how to install UNIX V6 on Bob Supnik's simulator from the tape file provided by Ken Wellsch. These setup instructions are aimed at the beginner level with regard to UNIX as well as to the simulator. The "bug fixes" are supplied as "diff -e" files on tp-formatted tape files, ready to be used by the simulator. Two simple ANSI-C programs are provided to insert (enblock) or remove (deblock) blocking information in tape files needed by Bob's simulator. Have fun, Wolfgang

[pups] Berkeley Pascal

by Lars J. Buitinck

I was browsing through the 2.11BSD docs on my OpenBSD PC, and I noticed I couldn't format the Pascal manuals. Can anybody format them for me in (if at all possible) PostScript format, or else plain TXT (with ^H_ and other more(1) hacks ofcourse)?

I do remember that being present during the debugging of 'ld' when the long symbol names (the "string table" aka 4.3BSD a.out format) capability was being developed. That suggests that 'ld' might be out of date. The answer to the 'Maximum PDP-11 executable size?' question is fairly length and a bit involved ;). Assuming split I/D: Short answer: 120KB to 904KB Long answer: without overlays there is one 64KB code segment and one 56KB data segment giving 120KB for a non overlaid program. In practice if a program hits 56KB out of 'ld' then there's no room for malloc() and the program may link but it won't run ;( For overlaid programs there is still but one 56KB data segment (the top 8KB is for the stack) but now the code can be arranged differently: There is a maximum of 15 overlays and there can be no 'gaps' (zero length/empty overlays between populated overlays). BASE OVERLAYSIZE TOTALTEXT 8KB 56KB * 15 840KB 16KB 48KB * 15 736KB 24KB 40KB * 15 624KB 32KB 32KB * 15 512KB 40KB 24KB * 15 400KB 48KB 16KB * 15 288KB 56KB 8KB * 15 176KB In reality the kernel probably would choke on the first several cases, and even if it didn't that large of a program would cause severe swapping. Most overlaid programs on the system ('vi' for example) use either the base=48KB or base=56KB layout. I think 'kermit' might use the 40KB base segment. The "tsize" error would indicate that the code size summing had an overflow - that was a bug at one time and was later fixed, which again suggests that the 'ld' is out dated somehow. If 'ld' was able to create 'xforw' try doing a "size xforw" on it and seeing how far it got - perhaps a clue can be gathered that way. You may need to usually terminate the overlay list with a -Y - I don't believe it's "required" though. -Z -lc -Z -lerrlst -Y ../config/version.o > is there any way around this, or is MH just too big to fix on a PDP? Couple things to try. Use 'size' on the .o (and/or .a) files to see how big things are - add them up and see if things start overflowing 16 bits. There was an overflow bug in ld's size computations - it was fixed by using a 'long' in a couple places to detect wraparound. What version of 2.11 (should be in the first couple lines of /VERSION) are you using? Sure feels like 'ld' is old and having problems that were fixed later on.

Ok - whew, for a minute there I thought some of my debug code had leaked to the world ;) That's the style of debug message I use <g> > /VERSION says: > Current Patch Level: 400 > Date: January 24, 1998 Ouch - that is a bit old, there are updates thru 434 (I've 435 in midstream but haven't had time to finish it). > That's what was on the PUPS FTP site.. Ah. Much becomes clear now. That indeed was the version at one time. A year or so ago I and Warren coordinated an update to the 2.11 in PUPS The current PUPS version is 431 (only 3 updates since then - I've slowed down a lot over the last couple years). > hm.. how do you specify the base segment size to ld? i don't see anything in You don't. At least not directly. Anything outside an overlay goes into the base segment. Thus anything before the first -Z goes into the base, and anything after the -Y goes into the base. > the manual page. Just link enough code into the base that it becomes the > right size? That's basically the way to do it. You can do "size" on the .o files first to get an idea what you want to put where but after that tuning the overlays to fit is a bit of an art. > text data bss dec hex > 27648 35860 32412 95920 176b0 total text: 83072 > overlays: 832,4352,2624,832,1920,29568,192,11008,4096 the single BIGGEST problem is that 'data + bss' exceeds not only the 56KB limit but the total 64KB limit available to a process. Looks like MH want 35860+32412 or 68272 bytes of D space. You might be able to get the code to fit - I'd pack the base to at least 40KB (more likely 48KB) and only have two or three overlays of 24KB or 16KB. THe data space problem means you're going to have to go and lower a lot of the buffer size limits. Remember: even if you do get the dataspace down to where the linker doesn't complain the program will almost certainly try to malloc() memory. Thus the smaller the data+bss the better - and be prepared for malloc() failures One thing that can be done is to run 'xstr' over the sources and collect error message strings, printf strings, and so on into a common pool. The other thing that can be done is create a strings file and extract as many as possible strings from the source modules into an external file. Examples of doing this type of thing can be found in the source tree - 'lint' was one such program, 'sendmail' was another and kermit yet another (that's why there are 'sendmail.sr' and 'kermit5.sr' files on the system). In fact 'kermit' is a good example of squishing a monster program into a small machine. Check out /usr/src/new/kermit5.188 > ld: too big for type 431 (problem 2: tsize = 0, ovrnd = -32768, dtotal = 0) > > the negative ovrnd i find very strange- perhaps the wrapround bug?

The size of the .a doesn't accurately reflect the code+text+bss For one thing 'bss' takes up no room at all in an archive. Don't forget that symbol tables and relocation information (as well as 'ar' book keeping info) is present. You can't rely on "ls -l" to say very much about an object file - only "size" can do that. "size libmh.a" will give a much better idea where the problem areas are.

Any way around this? I've tried all the combinations > i can think of, to no avail.. I think this would be a very good time to point out that 'data' is NOT overlaid, only the text is overlaid. There is but 1 data segment and all data+bss goes into it. Text overlays work because there's a very careful dance done by the assembler and linker. Functions use a 'thunk' (intermediate transfer vector) - thus when a program calls foo() it is really calling something like ~foo(). That thunk performs part of the function prolog and then checks if the overlay mapping needs to changeoa and if so makes a syscall to have the kernel twiddle the MMU. Then the thunk calls foo+4 (skipping the part of the function prolog that has already been done). Very elegant but completely unapplicable to data references (think on it - how is each and every pointer dereference to be checked to see if that data is mapped in?). In order to get the code to fit it would be necessary to extract all of the .o files from the .a file ("ar x libmh.a") and pack the .o files into overlays so they fit nicely. > > One thing that can be done is to run 'xstr' over the sources and > > hmm... a lot of work just to get MH working. Getting 32bit programs (and MH was done on a VAX or PDP10 (which is actually a 36 bit machine ;)) to run on a 16 bit machine is a lot of work. Since MH was written with a large address space in mind it will likely be necessary to go thru the code and find the "#define BUFSIZE 32000" or whatever and scale things back. The odds are good that many buffers are declared to be large just because it didn't matter on a big address space machine. That's what had to be done for 'vi', 'sendmail', 'kermit', etc. > > "size libmh.a" will give a much better idea where the problem areas > > are. > > unfortunately, size doesn't appear to work on archive libraries. Oh. Darn, I got my systems mixed up. On some systems 'size' will work on .a files - something to put on the TODO pile (shouldn't be too hard since 'nm' works with .a files).

So I'd like to put it there, but don't know how to. Well -- send a mail to warren k tomey (wkt@.... -- you'll find him in the mailing list). He has been building the archive and might tell you, how to transfer the files. Since PUPS-archive has an incoming directory, I think, it might be, that ftp-'put' to incoming will work. Warren or some other archive maintainer can pick it from there, and place it in the proper directories. Ask Warren. He is the one who should know. Regards -- Markus PS: Somehow I know your name.

Anything from 1 to 36 bits. Lazy people went with 9 bit bytes, while size-aware people used 7 bit bytes.

[pups] Sigma RQD11s, ESDI, and other naughty words

by norman＠nose.cs.utoronto.ca

A couple of weeks ago, I asked if anyone had any suggestions to help me convince a Sigma RQD11 Qbus-to-ESDI controller that it had disks attached. The trouble turned out to be pretty silly--the A-cable terminator in the disk I was testing with was in backwards--but later I discovered what may be a genuine controller botch that is worth reporting. Like most Qbus disk controllers, the RQD11 speaks the MSCP protocol to the host. More precisely it understands MSCP messages and uses UQSSP to transmit them; UQSSP is the transport protocol used by UNIBUS and Qbus controllers like the UDA50 and KDA50 and RQDX3 and TQK50 and so on. In general, the host sends commands like `bring drive online' or `read a block' to the controller, and the controller sends back response messages like `command succeeded' or `command failed.' (Never mind how the data part of the block is sent to memory for now.) The host sets up a ring of buffers for the controller to place messages in. Each buffer has an ownership flag: messages owned by the controller are available to hold new messages; messages owned by the host are not, usually because there's already a message there. When the controller has a message to send, it waits (if necessary) until it owns the next buffer in the ring (the ring is used in strict round-robin order); puts the message there; and sets the ownership flag to `host.' When the host has handled the message, or at least copied it elsewhere, it sets the flag back to `controller.' When the controller gives a message to host, it also generates an interrupt. There are several other reasons for generating an interrupt, so it is also supposed to set a single flag elsewhere in a communication area in host memory to mean `there are new messages.' My UQSSP driver code checked for new messages only if the flag was set, and that caused me grief; it turns out that, at least when the host is a MicroVAX III, the RQD11 sets the `new messages' flag inconsistently, or perhaps too late. Presumably it should have been set before requesting the interrupt, but empirically I can see that sometimes it gets set later. The effect was that the controller did what I told it, but my device driver never heard the acknowledgement that said it did. Obviously this makes I/O unreasonably slow. Fortunately there's a simple way around this: my driver's interrupt routine now peeks at the ownership flag for the buffer where the next message should appear. (Remember that the message buffers are used in strict order, so the host always knows exactly which buffer that is.) When I do that, all is well. I suspect that many existing UQSSP drivers already did what my code does now; in particular, the controllers and disks I am testing are known to have worked for many years with Ultrix, and while searching for data on the controller I came across various notes suggesting that the RQD11 works under NetBSD/VAX as well. But those who are writing new code or making changes to existing code should beware; the RQD11 appears to be breaking the rules (according to the old UQSSP manual I still have), and (as in many real-world protocol situations) if you write your code from the spec (as I did, in fact, albeit many years ago), the real world may trip it up.
