Subject: Problem(bug?) when running background jobs with X windows
Summary: Backgound jobs invoked under X would be killed after X exits
Date: 16 Dec 92 05:32:32 GMT
Organization: Project GLUE, University of Maryland, College Park

Hi, there,

I found a problem(maybe a bug?) when I try to do some background jobs under X.
If I send the job to the background and then exit X, that job would be killed.
This does not(and should not) happen for Sun Unix---all background jobs under
X would be still running even if you exit X.

Is this a bug with Linux, or Xfree86? Has anyone experienced this before?
I am using SLS 0.98pl5 with a 486/33, 20MB RAM clone.

Any help/comments is much appreciated!

I haven't been quite so lucky.  Twice now, I've managed to corrupt an
efs partition by starting to untar a large tar file (gcc-2.3.1.tar.Z),
realizing that I was going to run out of disk, and killing 'tar'.  The
first time, efsck couldn't save it.  So far it looks like I got lucky
the second time, efsck worked.  This is on a 386/20DX with an Intel
80387DX/25, 8MB RAM, and a 240MB Quantum IDE hard disk with two 63MB
efs partitions, one 12MB swap partition, and a 90MB DOS partition on it.

ok, this is the deal. the 24 is an et4000 but Diamond has a programmable
dot clocks on the board (the ones that drive the image).  Unfortunately
Diamon refuses to give information on how to program them without
the author signing a non-disclosure agreement.  The authors of XFree86
cant do this, because they need to make the source code available.

So that is the quandry. The solution is to program the clocks by another
method.  So, what people have been doing is booting DOS, running MS-windows
in the desired resolution and warm booting to linux.  Apparently the clocks
stay programmed across warm boots.

This is ugly, but one of the only solutions that have been found.  There
are 2 others that aren't so simple:

1) add a BIOS call to the Linux setup code that puts the clocks in the
write speed.

2) disassemble the bios of the card and find out how the cards are set.
This has been done by someone who announced his results anonymously: but
since the legal status of disassembled code is, to say the least, ambiguous,
there has been nothing (public) done with the results of this information.

Although I suspect if one looked around for it hard enough one could find
it...

Login as root, then:
	cd /etc
	mv inittab inittab.old
	elvis inittab

Within elvis type:
	ittys1:vt200:/etc/getty 9600 ttys1<ESC>ZZ

Note the small 'i' at the beginning which places elvis into insert mode. You
will also probably have to change ttys1 for your serial port (COM1 = ttys0,
COM2 = ttys1 etc.). The 'ZZ' at the end write everything into the file and quit
elvis.
Then you have to activate the new inittab by:
	kill -1 1
or simply by rebooting (which is probably better).

I think this could be done without a screen. Don't forget to connect DCD at
the serial port. Otherwise getty can get a SIGHUP.

I worked on it a little more, and I'm now getting quite reasonable
performance.  I'm not stupid enough to try to benchmark it, but under
the same conditions it appears to get about the same performance as the
RS/6000 I'm typing on right now.

	There is no need to do this with the current kernel.  The scsi code
correctly handles the situations where you have more than 16Mb memory, so you
might as well just let the kernel use all 20 Mb.

I don't have any solutions, but I have noticed something really bizzarre:

I have access to a lab of 486s. I ran linux on a total of three of them.
The all have an AMI bios and they all have the same bios date, so I assume they
are the same bios. Is there a software way to find out if they are the same?
Anyway, 2 of them had the problem, the other didn't. The one that didn't have
the problem is as follows:

486-33
4Mb ram
1.2 & 1.44 Mb fd
40Mb IDE drive
ET4000 1MB video

The other two were identical:

486-33
4Mb ram
1.44 Mb fd
40Mb SCSI, vendor NEC
Future Domain TMC950 controller
Trident 1Mb video

I can't open up the machines to check any further details since they are public
machines, but apart from that I can do much as I want with one of the scsi
machines. The other one died - I think its hard drive blew up. The IDE one no
longer has linux installed and now doesn't have any space to install it.
Does this help anybody?

I am having a serious security problem with the 'rm' command.
I have discovered that non-superusers can REMOVE files owned
by root. I doubt that such a serious bug could exist in Linux,
it must be something in my setup:

mkosina:NotSt0PgElMbo:100:6:Martin Kosina:/home/mkosina:/bin/sh

This is the /etc/passwd entry for 'mkosina', my user login.
This is a file in /etc that I will try to delete:

-rw-r--r--  1 root    root         62 Dec 11 21:02 rc.local

When I do 'rm rc.local' rm responds:

rm: remove `rc.local`, overriding mode 0644?

If I than say yes, it will be DELETED !

All other security works, read-only files deny permissions
to be over-written, processes refuse to be killed,etc.

I am running an out-of-the-box release of SLS p1-36.
This MUST be a permission problem somewhere, the only
thing I can think of is that SOMETHING runs setuid 0.
It should not be rm, though, here is what it looks like:

-rwxr-xr-x   1 root   root       5056 Sep  4 23:20 /bin/rm*

Any Linux gurus out there who can help me ?
Thanks in advance.

Martin

P.S. If this is indeed a bug in rm (or the unlink sys call ?)
which I doubt, could you tell me how to upgrade ? I can ftp.

I have a Gateway 2000 486/33C with Diamond SpeedStar Plus video card and
the dual frequency CrystalScan 1024NI monitor.  Release 0.97 worked with
it in most video modes.

This is not the case with 0.98 because it does not allow manual
selection of those modes and its automatic selection is wrong for my
video hardware; can't see a thing after the Loading ......... is
finished.  

Has anybody else experienced this problem besides me and is there a fix
for it?  I think it was a mistake to take out the manual video selection
option and I hope it will be placed back in the next release, with
perhaps a timer activating automatic selection after -- say -- 30
seconds if there was no manual selection.  (Similarly to boot manager
operation.)

It should work fine.  The only reason for the 1MB (as opposed to 16MB)
limit was that I originally thought of making only the low 1MB
identity-mapped, and anything above it could be moved around with the
pager hardware, so DMA wouldn't work on those without some address
calculations. 

As it turned out, I never did anything like this, and I currently
guarantee that all kernel memory is identity-mapped up to the limit of
physical RAM (it's easier on the memory manager, as well as on devices
like some SCSI cards which use DMA).  So changing the limit to 16MB
should work fine.  Not that it probably matters very much: 99% of the
floppy IO reads go through the track buffer, and writes aren't exactly
timing-critical in most circumstances..

        Using scanf to read from the modem doesn't work well because the remote

Command?" doesn't get received until later.  No good for a chat script.

        So I went to a character based input using getchar.  Still the modem
driver won't return a line of data until it receives a newline from the remote
system.  I then tried using the system IO calls open and read with no success.

        How can I access the modem on a character-by-character basis or have it
return lines without receiving a newline?
