True story: "gconfig" removed root folder...

True story: "gconfig" removed root folder...

[Ozan Eren Bilgen]

Hi,

Today I downloaded 2.6.1 kernel and tried to configure it with "make
gconfig". After all changes I selected "Save As" and clicked "/root"
folder to save in. Then I clicked "OK", without giving a file name. I
expected that it opens root folder and lists contents. But this magic
configurator removed (rm -Rf) my root folder and created a file named
"root". It was a terrible experience!..

Please fix this. I didn't check that same problem (I even didn't launch
them) exist for other configurators then gconfig.

I send this mail here because I guessed that the configurator is a part
of kernel.

Note: (As you wished) Please CC me your responses.


TIA

I only did a quick check with menuconfig. Are you sure it's really
removed? It should still be there as "/root.old".
I probably should change the behaviour of the save routine to behave
differently for directories as argument, but it doesn't remove it.
(Changing gconfig to only accept files in the save request would probably
be nice too...)

The real lesson here is "don't compile your kernel as root".  There's
no need to do so.

Yes, having your user homedirectory removed is *much* better :-)

gconfig behaviour aside, why on the earth are you running GUI code (_any_
GUI code) as root?

How about using /usr/src and giving permissions to that directory
to your non-root user?

So /usr/src gets removed instead.

That's not fixing the problem, it's moving it around the filesystems.

Would it really? If we use /usr/src/linux (for example) to store
the code of one single kernel and have a user with permission to
write to /usr/src/linux and not to /usr/src, then he couldn't
remove /usr/src, but only /usr/src/linux, right?

I'm not sure if I understand you correctly, and you might mean
that the problem in make gconfig isn't fixed. That's true, but
I'm not the maintainer so I'm just trying to help you find a
solution that will work for now.

Right.  It's not fixed.

Well, unfortunately, saying "Well, don't do that then" is about as much of a
workaround as we can manage till gconfig actually gets fixed.

What I'm worried about is a semi-clued user who will read the lkml archives,
see the "just do this" discussion, and think that it's actually a fix rather than
a retargeting of the ICBM ;)

What is (a) "root folder"?
The two words don't go together at all. Unix/Linux has "root" and
directories, but it doesn't have any "folders". Microstuff has
"folders", but doesn't have "root". Is Gates infecting Linux?
I heard that "folder" was a swear-word just like the other "f"
word.

The kernel doesn't impose a policy on user space, so a 'directory
vs folder' discussion is offtopic here. Let userspace decide.

I attempted to reproduce your steps but it did not remove my /root directory.
Instead of that, gconf created a .config file in the root dir.

Maybe I should avoid empty file name. It will be fixed in a further patch.

I have managed to reproduce bug: make gconfig, go to the '/' directory,
type 'root' as file and ... you get a 'root' file. The 'root' directory is
destroyed !

I am preparing a patch for gconf so that it can be protected against this bug.
Perhaps, you should protect 'conf_write(fn)', too ?

What do you mean with "destroyed"? All I can reproduce here is that it's
simply moved away, but it's still there!

Is it supposed to be moved away?  I'm just being curious...

Yes, this usually produces ".config.old", but there is nowhere a "rm -Rf"
as the initial mail suggests.

I mean "destroyed" because my 'root' directory did not exist anymore. When I do
a 'ls', I just see a 'root' file with config within.
Well, "destroyed" may not be the best word. I can tell that it vanished somewhere.
Anyways, I don't have any '*.old' file or directory after that.

[PATCH] Bug in patch of Romain: "gconfig" removed root folder...

[oebilgen]

Hi again,


Romain, I guess that there will be a segmentation fault because of:

   strcat((char *)fn, "/");

because:

   fn + strlen (fn) + 1

is not allocated for "fn" and strcat(3) may fail (may fail: It might
escape from segfault if gtk_file_selection_get_filename() has an indolent
allocation strategy for fn - like in "Vector" class of C++). It still is a
bug.

Try this. And Romain, this was my first patch (and also first bug report)
for linux-kernel, THX for your hint. I would lose too much time in order
to find store_file@linux-2.6.1/scripts/kconfig/gconf.c ;)


NOTE: I combined mine and Romain's patch, *** DO NOT APPLY BOTH *** !!!

To Doug McNaught and "viro"; running gconf as root it is not a must of
course but one couldn't be punished that hard. If you run gconf as normal
user, you still may experience this (a user friendly bug :P) by loosing
your (home) folders...


BTW, I looked to conf_write and saw that its char arrays are very
dangerous. I will hack it on monday, if possible. ("Open source groups are
like mafia; you can join but cannot leave")

Try 'ls -a' -- it sounds like the old one is being renamed to a name
that starts with a dot.

It would be nice if you could try to find out, what exactly happens with
the directory, the save routine does only a rename...

Um, I thought gtk++ also had an option that prevents the selection of
directories.
A test like this should be added to conf_write().

Isn t the policy as of administrator to use a test and an admin account ;
The former as a compile and check account the latter with installation
privilege.

Sure the process is left as administrator responsability but could this
sane behaviour be implmeented in distribution as part of source package
 installation.

What should I write then ? Your piece of advice may make me better.

Read Documentation/CodingStyle.  It is loosely based on the original
K&R style, where (the scarce) language constructs' arguments' opening
parenthese is prepended by a space, whereas with functions and macros
it is not.  I.e., one writes 'if (...)', 'while (...)', 'foo(bar)', etc.

Also, your explicit casts could use extra whitespace, like so:
"a = (int *) b;" not "a = (int *)b;"

When submiting code to an existing file, the general rule of thumb
is not to disrupt the style of that particular file, regardless
of what it appears to be.  You have managed to break this rule
_and_ the official CodingStyle.

You're right ! The save routine does on ly a rename. My 'root' directory is simply moved to 'root.old'.

Given that all stuffs are clear now, I'm preparing a patch for this.

What if stat() fails?

Hi,

This new patch includes Muli's remarks.
Need to be applied against a 2.6.1 kernel.
