Hi all,
what do kernel modules libaudit, klog and strlog do?
Specifically I want to determine if it was possible for us to determine if kernel level auditing is enabled at all?

Hi,
Does anyone know if it is possible to know the current value of a kernel module parameters after the module is loaded. Are the values of the parameters advertised at some /proc or /sys location ?
The only thing I know is modinfo, that actually looks a the module .ko and gives a... (3 Replies)

I am aware of debugging linux applications using gdb and ddd.
Now I have written a simple kernel module having init_module, exit _module and some functions for tasklets and workqueues.

How can I debug... (1 Reply)

Hey everyone. I have a question, doing an lsmod gives me a list of all the loaded modules for my system. But how did they know to load? my /etc/modules files is empty, so how did these modules know to load themselves on boot time? If I were to take this hard drive to another computer with a...

Hi,
I am running CentOS 6.5 and I want to remove auto loading 8021q and garp modules, but there are no configure files in /etc/modprobe.d define bot modules.

pivot_root
PIVOT_ROOT(8) Maintenance Commands PIVOT_ROOT(8)NAME
pivot_root - change the root file system
SYNOPSIS
pivot_root new_root put_old
DESCRIPTION
pivot_root moves the root file system of the current process to the directory put_old and makes new_root the new root file system. Since
pivot_root(8) simply calls pivot_root(2), we refer to the man page of the latter for further details.
Note that, depending on the implementation of pivot_root, root and cwd of the caller may or may not change. The following is a sequence for
invoking pivot_root that works in either case, assuming that pivot_root and chroot are in the current PATH:
cd new_root
pivot_root . put_old
exec chroot . command
Note that chroot must be available under the old root and under the new root, because pivot_root may or may not have implicitly changed the
root directory of the shell.
Note that exec chroot changes the running executable, which is necessary if the old root directory should be unmounted afterwards. Also
note that standard input, output, and error may still point to a device on the old root file system, keeping it busy. They can easily be
changed when invoking chroot (see below; note the absence of leading slashes to make it work whether pivot_root has changed the shell's
root or not).
EXAMPLES
Change the root file system to /dev/hda1 from an interactive shell:
mount /dev/hda1 /new-root
cd /new-root
pivot_root . old-root
exec chroot . sh <dev/console >dev/console 2>&1
umount /old-root
Mount the new root file system over NFS from 10.0.0.1:/my_root and run init:
ifconfig lo 127.0.0.1 up # for portmap
# configure Ethernet or such
portmap # for lockd (implicitly started by mount)
mount -o ro 10.0.0.1:/my_root /mnt
killall portmap # portmap keeps old root busy
cd /mnt
pivot_root . old_root
exec chroot . sh -c 'umount /old_root; exec /sbin/init'
<dev/console >dev/console 2>&1
