Subject: Ext2Fs questions
Date: Mon, 24 Apr 2000 21:29:50 +0300
Hi
I want to add a mechanism to separate the block allocation for file from
writing to it i.e. it will be possible to allocate a file of size X
without writing anything to it and no other file will ever get the same
blocks
( unless the file was remove of-course).
As far as i understood, the current implementations try to do the opposite
for example if a process seeks ahead 1MB and than performs write, it would
result with a file with "hole" inside.
The problem is that some high-performance application( like the one I'd
involve with ) would like sometimes to allocate the file first without
writing any data to it just to occupy the blocks, and later access it
directly, knowing that those blocks belong to their file.
To do this i must intervene with the ext2fs block allocator. so i need to
know some things
First how can i lock the blocks bitmap before taking control, to make sure
that
no other file tries to get the same blocks ?
Is it possible to lock only Block-Group block-bitmap or that i must lock the
whole superblock?
Second I saw that the block allocation function always writes zeros to the
block
before it returns its address.
This looks like a redundant action for my case which involves huge files
what
can results with big unnecessary slowdown for the system.
Is this really necessary or that it was only done to ensure that user won't
get
access to old data of other user ?
Is there a way to avoid the zero fillings or that i must write my own
allocation code?
Thanks in advance

Hey, if someone were to publicise claims of a back door in a DLL in my own
software, and I noticed that the DLL wasn't even necessary for distributing
the software, my first response would be "sure, delete it - you don't need
it anyway".
I wonder if you've bothered to see if your web server is even _loading_ the
DLL (simple test - try and delete the DLL while the server is running;
complex test - create your own DLL under that name that logs when it runs).
Alun.

Subject: System.map vs. /proc/ksyms
Date: 25 Apr 2000 04:16:02 GMT
I'm trying to compile a module which intercepts the unlink system call.
So far so good but I'm stuck on one point.
By using struct dentry I can get the id of the filesystem that my file
being deleted is on. How can I convert this id to the name of the mount
point?
I found lookup_vfsmnt but when I try to use it I get
./syscall.o: unresolved symbol lookup_vfsmnt
Now lookup_vfsmnt is in my System.map but not in /proc/ksyms
So my question is, what can I do to be able to use lookup_vfsmnt? If I
can't use it, what can I use instead to convert a filesystem ID into its
current mount point.
Thanks!
Dana

Subject: How legal is it???
Date: 25 Apr 2000 04:35:15 GMT
Hi there,
I'm thinking of creating a stealth application that will automatically
launch itself when the OS starts. I would like the application to
record the keystrokes made by users, and possibly the mouse movements as
well. Then, probably buffer these data and have them sent to a server
over the internet periodically.
Assuming that the user has provided consent for having this program
installed on one's computer, how legal will it be for such program to be
running under
a) Linux?
b) Windows 98/NT/2000?
I would expect this not such a big deal with LINUX, but what about the
privacy issue?
Any help or referral is appreciated.
Thanks a lot,
Steven

Well, naturally, 10 minutes after I posted this my husband found
ksyms.c. We added the symbol lookup_vfsmnt for exporting and now I can
load my module.
So my question is now
Instead of having to rebuild the kernel with the extra symbol exported,
is there a different way to convert a system ID to its mount point?
Thanks

No problem with any of this, as long as you have written consent.
Many businesses and Guvvermint offices are already using programs
similar to what you propose, and have used them for years...often
surreptitiously.

I want to set up my sparcstation 10 as a pure server (running redhat 6.2) and
so would prefer not to put compilers and dev tools on it, however, I do need
to be able to update the kernel and other apps... what's the best solution?
Is there a way to compile the sparc-bins on my x86 computers running
slackware... if so, are there any faqs or docs for me to consult? I've
searched around the faqs and don't see this mentioned at all... maybe people
who use ppc or alphas would have similar situation?
or should I just rely on rpms from redhat?

It is very legal. The corps have been doing it for years. It's
called 'productivity software'. It's a legal way to spy on your
employees. Now, in a more mainstream aspect, as long as your 'target'
gives you the ok to run this little app, no problem. If they don't, then
you could get into some problems. As for the privacy issue, it violates
every point of that, but hey! As long as Big Brother and the Corps are
doing it, why can't you? If you can write it, and package it without
letting the LUser know about it, then what's the worry?
Under Linux it's OK, but harder, as you may run into firewalls, and other
server side issues.
Under Win 9x you may get into problems with Micro$oft, but who doesn't.
If you even look at the licensing agreement wrong you violate it. "Click
yes to sign over you firstborn, or else the program will not work!"
Micro$oft sucks.

Subject: File formats for bitmap and vector data?
Date: Mon, 24 Apr 2000 23:34:01 -0700
I am writing a small application which verifies the format of graphics
files,
which students then upload to our web site (www.LaserEnlighten.com) for
laser-cutting. This application needs to import only the most common
formats of vector and bitmapped graphics on each platform - BMP, compressed
BMP, and DXF on windoze, PICT and PICT vector on the mac (actually anything
that QuickTime can read, which is a lot)... and ??? and ??? on Linux (please
fill in the ???'s!)
Also, if you know of any source code for reading these formats, that would
be appreciated. I want to make my laser cutting/engraving service, which is
designed for craftspersons and Industrial Arts/Fine Arts students, available
to all the major OS's, incl Linux.
Thank you,

Subject: My experience installing red hat from CD-ROM
Date: Mon, 24 Apr 2000 23:30:53 -0700
Maybe this will save someone some headaches - I tried on two PC's to install
red hat 6.1 from the CD-ROM after booting each with a minimal MS-DOS floppy,
just enough to access the CD-ROM with MSCDEX and the CD driver... and
neither Linux install could find the CD-ROM controller (one of which was
SCSI, and one Creative Labs/Panasonic). So I was quietly cursing Linux,
when I decided to make a boot floppy from the Linux CD, boot that, and try
the install - and it WORKED PERFECT ON BOTH MACHINES. (Sorry to yell.)
So even though installing from MS-DOS is outlined in the red hat docs as the
next best thing if you can't boot from the CD or from the floppy they give
you (BTW - my in-box Linux floppy was bad, which is what started this whole
adventure), I would not recommend it - make yourself a Linux boot floppy, I
think you'll be happier.

She's not the only one. CompUSA's Technology Assurance Program Owner's
Manual (from 1997) on page 14, under the section titled "Preventive
Maintenance for CPUs, Laptops, & Printers" continuously refers to a PC as
a CPU.
My favorite line is the one where they state they will "Remove dust/debris

glibc-2.1 *is* a minor increment. Formally it breaks binary
compatibility, as it locks away internal-only library interfaces, but
that only broke a few very badly behaved programs.

Use the "mem=x" command line switch for your kernel, to reserve some
space for you. After that you can use the remap_page_range function
to map the space. So you can use only the highest part of memory. If you
need other parts, write you own nopage-handler which maps this pages.

This is possible if you are really very familar with the internal of
the kernel. But in this case, you would'nt ask such questions;)
I'm not an expert, I can't help you with this.

Reply-To: [EMAIL PROTECTED]
Will this tool validate the xml tree structure to insure that the tags appear
in the order expected? Most validating parsers seem to make sure that:
1) there is a begin and end tag, 2) that the nested tags are ok i.e. has
and end tag. But they don't make sure that tags appear in a certain order.
So if I have
< book>my book
< title> my title</title>
<chapter>My chapter
<paragraph> my para </paragraph>
</chapter>
</book>
that the tag names appear in this tree strutured order and not some other
variation.
I can see that the tool(s) may validate the data in the tag agains't the
data type in the DTD, but not agains't the rigid tree structured order.
Unless I've missed something. The same applies to schemas.
What I'm trying to figure out is how they do the tree structure validation.
SAX doesn't create a tree ( it is event based). Thus, one must create the
tree which must be validated for structure.

you can build a cross compiler. do web search on "gcc cross compiler"
on google. to build anything useful, you'll need all the sparc
libraries on your x86 machine too. also afaik you won't be able to
generate 64 bit code from a 32 bit platform.
cross-compilers are for when your target has some problem supporting a
native compiler. most of the time it's for an embedded system which
barely has an operating system, too little memory and no disk, weak
I/O to a user and therefore cannot support editing files let alone
compiling. the other case is where you want to generate binaries for
windows and cygwin is painfully slow on NT.
however, i would what everyone else does. just break down and install
a compiler. it won't steal resources when you're not using it. (well,
except for disk space but that's cheap enough these days.)

I would think that this is what Modula-3 is all about (http://m3.polymtl.ca/m3)

I would use parallel port, since that should be easier for
your hardware part.
Hope that helps,
Martin.
