I have added a new system call for kernel version Linux 2.6.25-14.fc9.i686. after kernel compilation and running the user mode program i am getting the below error
Error :: Function not implemented

I cannot find the syscall_table.S or entry.S file in the source code , so i didn't made the entry of the syscall in this file, how much necessary the entry of syscall presence in this list and how to get this file?
My ubuntu version is 9.10
I was working on adding a call system to my linux kernel.
I tried a lot of threads and .pdf files which explaining how to add a system call. Like :
1- This thread
2- .pdf file
and many ..
I tried working with linux-2.6.18.1 , 2.6.33.1 , 2.6.28.1 and many many.
But , all of them are returning -1 as result ..
I prefer working on 2.6.28 kernel version or above like 2.6.33.1
Does anyone have straightforward simple example document for adding a system call on fedora 14 kernel?

In practice I have a script that call a java program that call a linux system command. The script if I run it, from a shell functions well,so it is not a java problem. The problem come out when i put this script in a crontab schedulation. The result in this case is that java do not execute the system command. I think it depends on crontab

View 6 Replies View RelatedI am searching for any system call similar to "ls" command we use in shell. My requirement is knowing the files and directories in curent working directory and process them based on there type. Here as of now I spawn another procees with system command like system
("sh ls -l | grep ^d | awk '{print $9}'").
Instead of this I want to use any system command where I can capture this information directly into my local character buffer. My opinion is that system calls will not spawn another process as a result less time it takes, another reason is once I use the system command again I need to capture the information to a local file then again read it into local buffer. I want to avoid the file manipulation here.

make *** [myfile.c] Error 4
which (according to /usr/include/asm-generic/errno-base.h) means "interrupted System Call". My preprocessor doesn't raise any signals, so I'm not sure what's causing this error.

I have code in several places that calls
reboot(LINUX_REBOOT_CMD_RESTART)
successfully. I need to put it into a new place in a application running on the system. When I do, it seems to just lock up the system and does not return from the call nor leave me able to Telnet in or Ping or anything. I've tried puttingtrace code in to write info out to a file, but that too is not working (as it never returns from the reboot() call.I don't get any error from reboot(), it just does not return and does not appear to restart the system.

View 1 Replies View RelatedI want to move my windows XP image from my old PC's C: and put it onto my new PC, with Ubuntu 9.10 already on it. Will this procedure work?First I'll burn an iso image of the windows C: to a CD or DVD, using the Win XP computer. Then, I'll load a (live Ubuntu), from my thumb drive and boot into my new PC, and move the Ubuntu partition to another location, in order to create the partition needed to install a Windows OS. I know that Windows, God bless them, needs to be first on the HDD. This procedure will destroy the grub loader.Then rebooting should load correctly to the grub bootloader, right?

View 3 Replies View RelatedI have a Dell Precision 330 with (the latest) A09 BIOS and 1 TB SATA hard drive. There is a SATA-IDE converter between the SATA HD and the ATA133 cable. The OS was Window XP Professional SP3.
When adding RH Enterprise Linux 6 onto the computer, I created two additional partitions, one 400 GB for Linux's storage and a 10 GB swap space. I chose Window XP as the default OS.
After the installation, when the system started up, I can hit a key to have two optional OS: Window XP and Linux. If I chose Linux, the system would boot up. If I chose Window XP, the boot failed with a message that windowssystem32configsystem was missing or corrupted. I read some articles that the problem can be fixed in window's recovery console with fixboot. After entering the fixboot command and restarting the computer, Window XP still failed to boot with an error message that another file was missing.
I thought I might have made some mistakes in the installation procedure and it would be cleaner to reinstall both OS. So I tried to install Window XP Professional again. Unfortunately, after booting from Window XP CD and formating the MBR and copying the window XP files, the computer can not restart with the installed XP. Instead, the computer boot from Window XP's CD repeatedly. If I remove Window XP's CD, the computer simply can not boot at all.
I began to wonder whether RH's Enterprise Linux made some change on the MBR of the HD that Window XP can not format.

I have a process that forks, where the childs puts some data of random size and exits while the parent should get the data and does some manipulation.. here I have used a pipe for child to write the data and parent to read the data.. Child simply dumps the data, and the data is of any size even child and parent doesnt know.
I have used select in the parent to see whether there is any data coming on the reading end of the pipe.. if there is a data.. I copy into a buffer.. Im reading the data continusly when the child exits after closing the writing end of pipe. Parent gets blocked on the read part But my question is how parent know the other of pipe is closed when using the select call. In otherwords.. while using select in readfds, how would i know the other end has closed the pipe..
I am trying to ptrace a process and when the system call is 'cd' change directory,
the ptrace process is able to trap it by comparing it against "__NR__open" system call. When I try to read the name of the directory from ebx register using peek_data I am getting ".message" and not the directory name.
The same thing works fine when I am tracing a file open system call.
