Yeah it's a pain in the arse.  I tend to compile things static these days -
using a dietlibc.

I suspect a lot of people ignore the costs and delays being added to user

After severly hacking a RH install I got a more or less comfortable
environment on my laptop,  and a not unreasonable boot time - so I
never suspend,  just shutdown... but the laptop'll be replaced soon,
so time to battle again - that'll be when plan9 gets a tryout on it.

right.  run strace on any given linux binary and watch the torrent of
system calls before main() even gets called.  it is truly appalling:

it's funny, i was probably looking at the source to the plan 9 date
command as you were writing that...

it's perhaps an interesting example.  i was looking back in the dump
file system and wanted to know the exact modification times of some of
the files there.  ls changes its format for files older than 6 months,
so:

% cd /n/dump/2003/0916/usr/rog/limbo/schedule
% ls -l scheduler.b

% ls -l scheduler.b
--rw-r--r-- M 30 rog rog 10183 Sep 15 22:07 scheduler.b
% 

and there i was, back in time 6 months, and the files display
their full timestamp as desired.

how pleasant it is to be using a system where almost all resources
are malleable, including time itself!

if someone supplies you a binary you could fork a shell without binding, clear the namespace and run the supplied binary. Like chroot & jailing it

However, preventing binds altogether seems a bit strange

if you fork with 

          RFNOMNT   If set, subsequent mounts into the new name space
                    and dereferencing of pathnames starting with # are
                    disallowed.
and

     RFCNAMEG  If set, the new process starts with a clean name
                    space. A new name space must be built from a mount
                    of an open file descriptor.  Is mutually exclusive
                    with RFNAMEG.

what can you lose from allowing the binary from manipulating it's own namespace?

How can I enforce static namespace semantics upon a process ?
Stop it from lying to its children about /dev/zero being /dev/random ?
Or letting them happily fill up the disk when writing to /dev/null ?

Regards,
Adi

Re: [9fans] x10

[Geoff Collyer]

I don't think that these are actual security problems.  Remember that
Plan 9 doesn't have set-id, so if you fool one of your child
processes, you can only hurt yourself.

Why do you want to enforce a static namespace?

Why would you bind /dev/random onto /dev/zero and why would you
consider it a security problem if you did?  Likewise for binding an
ordinary file onto /dev/null.

Plan 9, like Unix, will let you shoot yourself in the foot if that
makes you happy.  But shooting yourself in the foot is not a security
problem.

What's wrong with enforcing upon a process truerand() returning
random numbers and not zero every time ?

bind() may dramatically change the meaning of any file operation on
Plan 9 - and is itself not constrained by file permissions, etc.
Sometimes one may want to turn such a powerful feature off :-)

And generally, being able to control with rfork() flags the couple
of things Plan 9 still do without reading or writing files
seemed to me like a not completely ireasonable idea.

Of course, that may not be as useful as I first thought.

Regards,
Adi

Re: [9fans] x10

[Geoff Collyer]

If you want to make sure that you're getting the real /dev/random,
unmount /dev/random (but not /dev) first, or bind -b '#c' /dev again.

I don't think anybody has been persuaded yet that it's worth expending
the effort and increasing the kernel's complexity to restrict bind
with rfork flags.

Re: [9fans] x10

[Russ Cox]

> What's wrong with enforcing upon a process truerand() returning

If you start the process yourself, then you'll know that /dev/random
is okay, assuming you're not shooting yourself in the foot on purpose.

If you start an untrusted program and then have it start the process,
all bets are off, as you have observed.  But if you're letting an untrusted
program start some other program, you have other things to worry 
about -- like the untrusted program might edit the binary to remove
all the calls to truerand() before executing it.  Or might just not run
the binary and run its own entirely different version.  There's no
sense in trying to lock down this one thing.  The solution is not to
rely on untrusted programs to do your work for you.

Russ

Re: [9fans] x10

[rog]

the reason this is a problem in unix is the setuid bit.  various setuid
programs expect to see files (e.g./etc/passwd) in their expected
place.  if you can replace 'em, you can break the system.  hence
chroot is a superuser-only system call.

if you don't have setuid programs, it's not a problem.

as far as i can see, this was one of the major "too deep to fix"
problems with unix.

And that is the crux of the matter.  You invent to do stuff help
create a product and sell it.  We (society) will give you a monopoly
on it for a very limited time if you tell us how you do it.  We will
stand on your shoulders and do new stuff based on what you have told
us.  Also, in 17 years we get to make more of them.

encourage Englishmen to figure out how the French were doing all the
fancy stuff they were doing in textiles.

This link, from the thread "Rob makes Dave Farbers 'vanity publishing' list":
	http://www.interesting-people.org/archives/interesting-people/200404/msg00066.html

also makes the argument that in a very big deployment - they have
100,000 servers, each with 2 disks (yes, I counted the zeros!) - RAID
doesn't make much sense. I was convinced.

system attached. I haven't the bandwidth to use it myself, but someone at
cooper I introduced it too uses it on his home network and loves it. He

no, i don't think it does. regardless of what model you use,

always security questions. the fact that the specific apt-get

RAID controllers are expensive, overly complex and prone

however i was compelled by his logic that the controller
i was using [Digital Storageworks] expensive and
probably over complex.

I'm just hoping they can maintain the record, given that the

10,000 (numbers off the top of my head, but you get the general

  Yam, apt for rpms, etc are trying to add the fundamental mechanisms

This is also mostly true, but having used Debian Linux for several
years now, I can claim with some non-trivial experience that Debian is the
counter example (that proves the rule? :-).
Debian linux, like the BSDs also tries to release a 'system', not
just a collection of packages. That is why the Debian release cycle
is so long, and why the 'latest and greatest' version is always
rather out of date!

I apt-get modules daily (or at least, weekly), and have never had
one program/library break another, or any of the usual library-version hell.

Of course, if you step outside the packages in the stable system, then
things can get a little more complicated, but that is your choice, and
usually the package system still sorts things out with very minimal
hassle.

Just last week I apt-getted a reasonably recent version of gnucash,
and that was all there was to it. Nothing broke, all the dependencies
were automatically updated, etc. etc. No scheme-version hell, either.
(It's just a pity that the up-to-date manual hadn't also been packaged,
but that only took a few minutes to fix).

The number of times you see instructions for the installation of packages
on RPM-based systems include the direction to "turn off package version
compatibility checking" is truly scary! I'm not even sure if apt has
such an option!

Re: [9fans] x10

[Kenji Okamoto]

Thank you, geoff.

In a short word, my argument is that we should pay more respects to those
who are sharing their own time to others.   Of course, I know we can employ
more people with high quality if more money.   This is true everywhere 
professional works are concerned though.   

It's easy to say that quality of some free software are bad from the view point 
of skilled professionals.   However, we must remind that the programmer who 
are working without pay are shareing their own time, not full-time of them, 
which is same to us after Plan 9 became to a free software.   As you know the 
quality of Plan 9 itself is now going down, if we cpmpare it with ,say, Release 2 
or 3.   I think this is very natural, because we have now no full-time programmer 
of Plan 9.

Being said above, I still love Plan 9 because of its beatiful design and codes,
very easy to understand and to read!   I feel Plan 9 has her own future, if we 
could continue to develope its philosophy.   The problem is how we can get 
more programmer even though we cannot pay them money in a future.   I think 
Linux people may have a solution or at least trying to get it with struggling.

My preference is only Plan 9, because I don't know Research Unix.☺

I chose Linux because it's the best spread lunix, and I can use it as my own
base for working (actually, I may not need sources of it, because it's just a
running base for applications to me).   From this view point, I doubt there is 
any value to pay attention to other Unices, because we have Plan 9.

// Just look at the world of Windows. Where is all the
// BSD licensed Windows software?

um, there's not exactly a *ton* of GPL code for Win32, either. some, sure,
but the dearth of both is due, i believe, do the nature of the underlying
system. 

// With no GPL I'm willing to bet that plan9 would not have gone open source...

while i'm not willing to take that bet, i'm not backing it, either. several of
the labs folks have been fighting with lawyers to get as much out the door as
possible for years before the GPL was the force it is today. and i believe the
shift in the lawyers ability to listen is due more to changes in the world at
large than to the GPL (although it likely helped).

that said, you point is probably valid: it's certainly been the case with
various hardware manufacturers that produce drivers for linux that wouldn't
otherwise be likely to give out the info.

anyway, i'm not looking to put down the GPL. it's fine for what it is and
what it does. it's actually *especially* useful for companies producing their
own code, all FUD aside. what strikes me as "bad" is the idea that the GPL
has a moral advantage over BSD/MIT licenses.

anyway, tangential references to plan9 aside, this has gone fairly far off
topic. whatever license you like is fine: if i don't like it, i simply
won't use your stuff. there's always a choice.

all americans are either cowering in their duct-tape-sealed homes

By the way, it seems that the free software movement may have
shifted to Europe these days.   I got region 1 "Gangs of New york",
and had to setup my Linux box to enjoy it.   The ogle movie free
software is from se domain...   What is happening in US these days.

Damn!

All I need is a place to live, a load of X10 stuff and a plan9

I've pushed to sources a program called lights,
that is a gui for the x10 file system. It can be used to
see the status of lights/sensors and to change them by
using the mouse.

The file system (cm11 driver) has some bugs fixed too.
