Build kmodule manual
pull kmod from remote
Pull kmod source code in submodule.
git submodule update --init --recursive
install kmodule
pip3 install kmodule (prefered)
python3 setup.py install (not prefered)
Build kmodule
python3 setup.py build (Used by dev)
Build sample
Download Linux kernel sample module hello-5 from
Confirm Makefile, hello-5.c and sample.py exist.
Install build kernel module required toolchain, header files and libraries.
Goto hello-5 folder, run
make
python3 sample.py
Example (python invoked as root)
>>> import kmodule as km
>>> mlist = km.lsmod ()
>>> for m, v in mlist.items ():
... print ('======================')
... print ('name: %s' % v.name)
... print (' v.size: 0x%X' % v.size)
... print (' v.opened: %d' % v.opened)
... print (' v.status: %s' % v.status)
... print (' v.offset: 0x%X' % v.offset)
... print (' v.usedby:', v.usedby)
======================
name: psmouse
v.size: 0x25000
v.opened: 0
v.status: Live
v.offset: 0xFFFFFFFFC03E2000

======================
name: cryptd

v.opened: 3
v.status: Live
v.offset: 0xFFFFFFFFC04A9000

>>> km.insmod ("hello-5.ko")
>>> km.rmmod("hello_5")
>>> minfo = km.modinfo ("hello-5.ko", "e1000")
>>> print (minfo)

Usage
lsmod()
NAME
kmodule.lsmod() - Show the status of modules in the Linux Kernel
DESCRIPTION
kmodule.lsmod() is a trivial program which nicely formats the contents
of the /proc/modules, showing what kernel modules are currently loaded.
RETURN
Dict with module name as key, value is class _lsmod if success. Exception if fail.
DATA STRUCT
class _lsmod(object)
Data defined here:
name
module name
size
module size
opened
module is opend
status
module status
offset
offset in memory
usedby
mouses using this module.
modinfo(*modules, basedir='', kernel=None)
NAME
kmodule.modinfo - Show information about a Linux Kernel module
DESCRIPTION
kmodule.modinfo extracts information from the Linux Kernel modules given
in python.
If the module name is not a filename, then the /lib/modules/version
directory is searched.
kmodule.modinfo by default returns every attribute of the module in dict.
The filename is listed the same way (although it's not really an attribute).
OPTIONS
basedir
Root directory for modules, / by default.
kernel
Provide information about a kernel other than the running one.
This is particularly useful for distributions needing to extract
information from a newly installed (but not yet running) set of
kernel modules.
For example, you wish to find which firmware files are needed by
various modules in a new kernel for which you must make an
initrd/initramfs image prior to booting.
RETURN
Dict in tuple if success. Exception if fail.
RETURN DATA
(dict1, ... dictN)
insmod(module, **params)
NAME
kmodule.insmod() - Simple program to insert a module into the Linux Kernel
DESCRIPTION
kmodule.insmod is a trivial program to insert a module into the kernel.
Only the most general of error messages are reported: as the work of
trying to link the module is now done inside the kernel, the dmesg
usually gives more information about errors.
RETURN
None if success. Exception if fail.
rmmod(*modules, force=False, syslog=False, wait=False, verbose=0)
NAME
kmodule.rmmod() - Simple program to remove a module from the Linux Kernel
DESCRIPTION
kmodule.rmmod() is a trivial program to remove a module (when module
unloading support is provided) from the kernel.
OPTIONS
force
This option can be extremely dangerous: it has no effect unless
CONFIG_MODULE_FORCE_UNLOAD was set when the kernel was compiled.
With this option, you can remove modules which are being used, or
which are not designed to be removed, or have been marked as
unsafe (see kmodule.lsmod()).
syslog
Send errors to syslog instead of standard error.
verbose
Print messages about what the program is doing. Usually rmmod prints
messages only if something goes wrong.
RETURN
None if success. Exception if fail.
