Nope, haven't done it yet.  Thanks for the heads up, though.

Off the top of my head, I can't.  I have just been writing plain text
for the moment, I write better that way.  I'll be working on
formatting/markup hopefully next week.

Ah, yes. I see. This just jumps in my eyes, after i upgraded.
Ive attached the output of the latest cvs. Maybe it is helpful?
It seems that cpu AND disk is broken - or maybe my config?
This is happen after a compile-run on a 2.6 Kernel.

Nice to see, whats already done.

No, you didn't, but we did :-(

with kernel 2.6, /proc/stat does not contain a disk_io line anymore. 
Looks like this info has moved to /proc/diskstat.

I have to write another plugin for this.

[Lcd4linux-devel] function naming changed in CVS

[Michael R. <re...@eu...>]

Hi there,

I jhust changed lots of function names in CVS to follow the plugin::name 
convention. This may lead to unusable configurations, so double-check 
your lcd4linux.conf for function names!

Furter, this is important for the documentation guys! If you already did 
a "grep AddFunction *.c" to get all plugins, please do it again.

If I have a look at the Status file, we're heading for 0.10 Real Soon 
Now(tm)!! There's one display driver missing (Beckmann+Egle), all other 
drivers have been ported, all plugins have been ported. But 
documentation is missing!

Anybody with a Beckmann+Egle "Mini-Terminal" out there? I need a tester 
for porting the driver....

Can anyone tell me how to write documentation? I didn't follow these 
discussions...

[Lcd4linux-devel] Widget Disk & Diskbar isnt working anymore after 2.6.6Kernel-Update

[<An...@t-...>]

Hello List (again).

I upgraded to the 2.6.6 Kernel on my gentoo system and it seems that
the Disk-Widget and Diskbar-Widget isnt working anymore? Did i miss
something in the Kernelconfig?

To Xavier:

Thanks again. I didnt read the Status-File in the Archive. There i 
can see also, that the virtual-rows and scrolling are not implemented yet
or in the ToDo-Status.

Sorry for this obsolete question! =)

Thanks in davance,
Andreas

Well, this may be a clean solution. BUT the same race condition is here:

if(file is a symlink) {
    error and quit
}
/* possible race condition here */
open (file, O_CREAT)

> Moreover, I

Believe me, he is. He could try to do that i a loop, create some 
tousands of symlinks a second. Then he just has to wait...

Your approach is one of the reasons for at least some of the security 
holes out there.

Or you should do
if(file is a symlink) {
    error and quit
}
before writing to the file. So, there's no problem anymore. Moreover, I
don't think the user is able to create a symlink within the small delay
between the if and the open.

Yes, that's easy, but contains a race conditions:

if (file exists and/or is a symlink) {
    unlink (file)
}
open (file, O_CREAT)

This one looks clean, doesn't it? But there's a small window just before 
the open() call, where a hacker could create the symlink, and it's 
contents would be overwritten by lcd4linux.

You absolutely _have to_ use atomic operations here.

Maybe you should do it like I did in plugin_i2c_sensors to check we have
a directory :
it did "if ((dir->d_type!=DT_DIR && dir->d_type!=DT_LNK)" to check if
it's a dir or a symlink. You should check if it isN'T a symlink but a
true file. I don't know how to get this d_type for a special file, I did
it with readdir.

[Lcd4linux-devel] make lcd4linux secure!

[Michael R. <re...@eu...>]

Hi there,

I want lcd4linux not to contain any potential security holes. As we 
don't have any networking, no client-server-model, no other fancy stuff, 
this risc is quite low. But lcd4linux is running as root, and therefore 
potentially dangerous.

I'm worrying about a symlink security hole: The Image driver (was: 
Raster) creates files, without checking if they exist. If a user places 
a symlink, he may use lcd4linux to overwrite arbitrary files. Which I 
consider not to be nice.

The output file of the raster driver is passed with the '-o path/file' 
option. To enshure that a potential reader always gets a complete file, 
the image is first written to a temp file, which will be rename(2)'ed 
afterwards.

I see two problems here:

1. the temp file is opened with O_CREAT. If a symlink is already 
present, it's target will be overwritten. Some security HOWTO's say one 
should use O_CREAT|O_EXCL, which means that the call will fail if the 
file already exists. OTOH, the open(2) man page states that thios 
doesn't work over NFS :-(

2. the rename() will overwrite a symlink, too.


Anybody out there with the experience how to solve such issues? I didn't 
find too much documentation out there, especially not for exactly the 
cases we're dealing with here.


thanks, Michael

If you look at the "Status" file, you can read :
For 0.10.1 :
- add events/input layer
- support "virtual rows" (will be done with events)

[Lcd4linux-devel] FASD project: Online survey launched

[<ben...@id...>]

Dear Open Source developer

I am doing a research project on "Fun and Software Development" in which I kindly invite you to participate.
You will find the online survey under http://fasd.ethz.ch/qsf/. The questionnaire consists of 53 questions and you will need about 15 minutes to complete it.

With the FASD project (Fun and Software Development) we want to define the motivational significance of fun when software developers decide to engage in Open Source projects. What is special about our research project is that a similar survey is planned with software developers in commercial firms. This procedure allows the immediate comparison between the involved individuals and the conditions of production of these two development models. Thus we hope to obtain substantial new insights to the phenomenon of Open Source Development.


With many thanks for your participation,
Benno Luthiger


PS:
The results of the survey will be published under http://www.isu.unizh.ch/fuehrung/blprojects/FASD/.
We have set up the mailing list fa...@we... for this study. Please see http://fasd.ethz.ch/qsf/mailinglist_en.html for registration to this mailing list.

AW: [Lcd4linux-devel] The HD66712-thing...

[<An...@t-...>]

Hello Xavier !

Hm. I dunno why the Icons Option wasnt in the conf-file anymore.
But now ive managed it. The Icons work fine here how. I didnt
realized that ive to use the Icon-Options in Drivers together
with the Icons itself, thought, that if i put the Icons Option in, that
i get one of hmmm kinda test-icon with that number or so.
Now ive understand and can use it and i find this fascinating. =)

Now i would like to use the scrolling thing. But i dunno where and howto
declare it. Also in the drivers section and just fill more Rows
than my display have? Or in the Layout Section?

Thanks for your fine help.

Andreas

Re: [Lcd4linux-devel] The HD66712-thing...

[Xavier V. <xav...@fr...>]

Hello Andreas !

As I suspected, it's a configuration problem. As there are only 8
user-defined chars in these displays, Michael decided to have a "Icons"
config option which defines how many chars must be kept for icons, and
the other are used by bars. If you don't set "icons", you don't get
icons ;)

My lcd4linux.conf looks like this :
----------------------------------------------------------------------
display HD44780 {
    driver 'HD44780'
    model 'generic'
    port '/dev/parports/0'
    bits '8'
    size '16x2'
    icons '2'         <----- here's the claim
}

[Lcd4linux-devel] The HD66712-thing...

[<An...@t-...>]

Hello List.

Okay, i do some experiments. I still have no success with icons.
I compare it to the ouput of the XWindow Driver where all seems
to be okay. Just only the icons wont appear on the display. 
The bars and all other work fine. I would love the EKG in one
corner or anything like that. =)

I attached the Config File and the output of lcd4linux with -vvv
option. I dont think this helps much, cause i can see any 
relevant information regarding the Icons...?

Anyway i attached both, the config-file and the output.
The config file is nearly unchanged like its in the archive as i said.
The errors are okay, i guess since i configured nothing in this direction.

I would be glad if i can help this thing get to work.

Thanks in advance,
Andreas

It's up to you to decide what to do. I'll send you a tarball this WE

Err... the framework is done (and the CSS is CSS2 valid !), but as Michael

In fact, it's the same as the one I sent you last week, with some minor

The best think would be to wrte the "general" part (lcd4linux dir), but
maybe it's too hard. The best to begin would be to write doc for
drivers/plugins you understand (greping the configuration options).

Oh, ****, I forgot the helper to add a synopis with configuration
options ! I'll do it this WE.

A good idea. I try to find some more time for lcd4linux, and I think we 
should at least release a "beta" of 0.10 Real Soon Now (TM). But without 
any docs, this would be quite useless.

A good thing for writing docs is a "grep cfg_get" and "grep cfg_number", 
you'll get all config file entries for a specific driver and/or plugin.

Strange, very strange. For the bars working, I don't thinks it's a 
problem with the HD66712, because internally they use the same logic for 
user-defined characters.

I'd try to add a "X11" display section and try your config with that 
one. If this is not working, too, there may be a real problem with your 
config. If itr works, there may be a problem with the HD66712. In this 
case, pelase send me your config file and the output of 'lcd4linux -Fvv'


bye, Michael

Xavier, where are you at on that framework?  I looked in CVS and didn't
see it yet...  

My intention this weekend is to start writing documentation for the 
functionality currently in CVS.  For the time being, I'll write docs
in plain text and format them when the framework becomes available.  I
won't be connected this weekend but I pulled from CVS last night.

I think it only depends on the guys behind a project and the
will to invest in such a baby... =)

Ok. This thing is compiling fine now. And all of the Widgets
are working (also the kinda-splittet bars). But i cant get
it to work with animated Icons or the "Lightning", also if
i disable all bars. I think there is something different
with the HD66712. But i dunno, whats different
cause the bars work and they contain (as i understand)
also some "icons" (the half blocks?).

This is a link to the Technical Papers of that Controller.
Maybe one of you can see any difference?
I guess this display becomes popularer until now, since
www.kernelconcepts.de is selling such beasts here in
Germany for a moderate price. Completly wired like the
Winamp-Wiring-Method, with a nice Adapter"card" to stick a
Parallel-Cable on it.

Hm. I use one of the sample-configs and modify it slightly to match the
choiced Display. Maybe you got a low-level config you can hand me? Ive just
tried like you wrote and no Icon appear - i still cant understand why the
bars
working on the other hand?

Again any ideas? Hope not to bother you all.

Thanks in advance...
Andreas

In fact, I've never heard about this model, but if it's hd44780 compatible, it must support icons too.
I suspect a problem in your config. Try with no bar and a "Icon x" entry
in the Driver section (x is the number of icons to allocate).

Yes, free software is cool, that's why we write this program ;)

PS: you should try Thunderbird, it's really cool. I used to run Sylpheed
too, it's ligher, but less nice (and works in zindoz).
