Re: [leaf-devel] Allowing Weblet to change a root file
Brad,
Thank you so much for pointing me in the right direction.
I have my shell script, toggle_udp, which checks to see if
ip_masq_udp_dloose is set to 0, and if so, it sets it to 1 (and vice-versa).
I also just found a little C code snippet on google that I think should do
what I want. This is what I have:
---
#include stdio.h
#include stdlib.h
#include unistd.h
#include string.h
void main(void)
{
int status;
status = setuid(0);
if(status == -1){
fprintf(stderr, Error setting uid to 0\n);
exit(1);
}
system(/var/sh-www/cgi-bin/toggle_udp);
exit(0);
}
---
Now my only problem is, how do I compile this to run on Leaf? Is there a
compiler available and small enough to work on the system? Or would I have
to compile it elsewhere, and then move it over to leaf? If this is the
case, I only have access to machines running windows or solaris. Would
anyone be willing to compile the small program above for me?

Would anyone be willing to compile the small program above for me? That would make it tough. It's probably possible to cross-compile from one of those platforms for a x86 glibc 2.0.7 target system, but just thinking about setting up the development environment makes my head spin. ;) Sounds like Jon hooked you up with a compiled version, so hopefully you're set now. --Brad [1] http://leaf.sf.net/devel/jnilo/uml.html --- This sf.net email is sponsored by: Influence the future of Java(TM) technology.

Re: [leaf-devel] Allowing Weblet to change a root file
Less secure would be to do the same thing with a setuid shell script. It's my understanding that shell scripts will not work suid. (I did try that out before turning to C, it never worked, and I seem to remember seeing an explanation of why it doesn't work somewhere...) CCMIW For the record, linux will *NOT* honor the setuid bit on shell scripts...there's just no practical way to make them secure. Also on the security front, I would strongly suggest directly modifying the desired /proc flag with the C code, rather than calling any sort of shell script. There are too many ways to manipulate the shell if you're not careful, and while you probably don't have to worry about a lot of these problems on LEAF (which typically isn't setup with user accounts), I never like taking shortcuts with security...it's too easy to build bad habits and forget yourself when it really *DOES* matter.

RE: [leaf-devel] UML development slink filesystem missing kernel headers
Hi Fabrice, The last thing that I read from Jacques on this was, Don't do kernel work under UML slink. Unfortunately I was unable to find his original message to refer you to but in a nutshell it said to do your kernel work on a traditional Linux installation. Hope this helps, Eric Kiser -Original Message- From: [EMAIL PROTECTED] [mailto:leaf-devel-admin;lists.sourceforge.net]On Behalf Of Fabrice LABORIE Sent: Monday, October 21, 2002 11:38 AM To: [EMAIL PROTECTED] Subject: [leaf-devel] UML development slink filesystem missing kernel headers Hi, here are some updates trying to compile a USB-Modem driver ( but still NO solutions )! Since the kernel header didn't come in the root_fs_slink, I decided to download the kernel source into my UML devel box ;-) Since the kernel source uncompressed didn't fit, I created a BIG_root_fs_slink identical to the original but 400MB large (by basically using dd,mkfs, mount -o loop , cp -a ,nmount ) Running a make menuconfig and a make dep inside the UML created the missing /usr/src/linux/include/linux/modversions.h . Great ... BUT - trying to compile my USBdrivers show some problems in the kernel header ( /usr/src/linux/include/linux/kernel.h in particular ... but then plenty of other problem) - trying to compilego further in the kernel compilation shows the same error messages. so i was wondering if I should follow the steps given in chapter 5 How to build an UML kernel for LEAF it would make sense ..: maybe the problem above was that I was tring to build a i386 kernel ( or at least get the matching headers ) in a ARCH=um environment... trying to follow those steps, I applied all the patched ( bering+uml) ( replaced the make xgo in freeswan-X.XX by make menugo root_fs_slink didn't come with wish) ... but as soon as you save the .config file from the freeswan error message started to flow :( and also error messages when typing the make linux ARCH=um ... I also tried to skip the freeswan part going directly to the make linux ARCH=um but no luck same kind of error message :( bottom line ... i am a bit stuck now :( any suggestion ? thanks fabrice. - Original Message - From: Fabrice LABORIE [EMAIL PROTECTED] To: [EMAIL PROTECTED] Sent: Monday, October 21, 2002 1:49 PM Subject: UML development slink filesystem missing kernel headers Hi guys, I am trying to compile the drivers for a Aztech 56K USB modem... This is my 1st attempt to play with UML the USB/linux drivers from http://www.smlink.com/download were working on my previous machine RH7.3 ( I also gave it a try with the compilation on RH80. make succedded ... ) it seems that the Leaf_UML Debian slink recommended in the Using a Virtual Debian/slink development box doesn't include kernel include/header... downloading the kernel2.4.18.bz2 to extract the source didn't help much ... (a file is still missing mod_versions.h that I believe is created when you compile the kernel...) any suggestions on how to be able to compile kernel modules under Leaf_UML ? - a bigger uml filesystem with the full development environment? - a debian package to install ( similar to rh8.0 glibc-kernheaders-2.4-7.20 ) that would install the 2.4.18 headers for slink ? ( I am no debian specialist ... and my search on the debian site wasn't really successfull ... - ? (alternatively, i'd accept the drivers for my USB modem is someone can compile them ... but I'd also like to learn the process to be more independant in the future) thanks for your help.

Hi Jacques, can we have a module for 3c509 cards usually 3c509.o or can some other driver work? I hope was not blind when I looked for it. I found 3c59x.o, I think that would not work. in bipack2.html section 12.7 how many other pcmcia kernals are there? you said three I found two others for a total of three modules. pcmcia.lrp, pcmcia_xicom.lrp, and pcmcia_ornoco.lrp.

[leaf-devel] Re: draft Bering DiskOnChip user guide chapter
Marck, On Tue, 22 Oct 2002 10:32:58 -0400 Mark Meade wrote: Hi Brad, Your instructions look great -- well written and concise. Thank you for taking the time to read my work and make suggestions. One suggestion: the mtd modules in 2.4.18 won't work with any DiskOnChip devices formatted with newer revisions of the M-Sys DFORMAT utility (5.x or later). An earlier version (4.2 -- still available at www.m-sys.com) is needed to insure compatibility with 2.4.18 modules. The failure occurs when loading the nftl.o module. This issue has been fixed in newer versions of the DiskOnChip modules. I will note this in the instructions. Do you know if partitioning and formatting a DFORMAT 5.x formatted DoC with fdisk/mkfs makes any difference? Will using GRUB eliminate this issue? The DFORMAT command creates one FAT partition by default, so running fdisk and mkfs.msdos may not be necessary. That is what I figured. My DoC was already formatted. I will add a note to that section to say it may not be necessary. Regarding the mounting twice problem: I tried this today (with newer versions of the modules), and it seems to work fine. I'm assuming that simply mounting the DoC twice, in two different places, is similar to what's going on in the root.linuxrc script; for instance: mount /dev/nftla1 /mnt/doc1 mount /dev/nftla2 /mnt/doc2 Actually, the same partition is mounted twice like this: mount /dev/nftla1 /mnt/doc1 mount /dev/nftla1 /mnt/doc2 If you are able to test that scenario with newer drivers than are included with 2.4.18, I would like to hear what happens. Can you also tell me what version of the the modules you're using. Also, it's possible to replace the proprietary M-Sys DoC firmware with the GNU GRUB bootloader. There are two compelling reasons to consider this option: 1) GNU GRUB is licensed under the GPL 2) The M-Sys firmware takes up considerably more memory than Grub Disadvantages to this option include the additional steps required to build and burn the Grub firmware, and also the DoC support is not yet part of the main Grub source tree. If anyone is interested, the procedure to do this is documented at: http://lists.infradead.org/pipermail/linux-mtd/2002-October/006166.html It appears the linux-mtd archives are unavailable right now. At the least I will add a link for the curious as a footnote in my instructions. If I can make time to try it out, I will incorporate the GRUB instructions into optional steps in the DocBook instructions.
