Embodiment shall fall within the protection scope of the present invention.
Fig. 2 is the flow signal of the setting method of device file permission in a kind of kernel module provided in an embodiment of the present invention
Figure, this method include the following steps：
Under S101, the kernel module file copy to root file for generating compiling.
The present embodiment is applied to Android handheld equipment, such as mobile phone, tablet computer etc..
In the prior art, the ko files compiled by obj-m be positioned over handheld device system lib
Under modules catalogues, the present embodiment by under the kernel module file copy to root file compiled by obj-m,
As shown in Figure 1, the root file and system are files arranged side by side, kernel module file xxx.ko correspondences/xxx.ko.
S102, the permission of the kernel module file is set for executable permission.
After under the kernel module file copy to root file for compiling generation, kernel module file xxx.ko is changed
Permission (such as chmod 777/xxx.ko), it is allowed to have executable permission.
S103, the loading kernel module file, create at least one device file.
A series of equipment text of kernel modules of registration establishment can be driven by loading kernel module by insmod/xxx.ko
Part supplies application operating.
S104, setting at least one device file permission be the required permission of application.
After loaded kernel module xxx.ko, it is that application is required to need to change the access rights such as the read-write of device file
Permission.
S105, the application is received according to described using access of the required permission at least one device file.
After completing above-mentioned priority assignation operation, it is possible to access equipment file.
The setting method of device file permission in a kind of kernel module provided according to embodiments of the present invention generates compiling
Kernel module file copy to root file under, setting kernel module file permission be with executable permission, add
Kernel module file is carried, creates multiple equipment file, the permission for setting multiple device file is to apply required permission, so as to
It can receive using the access to multiple equipment file, using no device file operating rights when preventing from loading kernel module automatically
Limit.
Fig. 3 is to the setting method of device file permission in a kind of kernel module provided in an embodiment of the present invention shown in Fig. 2
The flow diagram further refined, this method include the following steps：
S201, the compiling mode of kernel module is revised as obj-m by obj-y, the open source protocol of linux is revised as private
There is agreement and the kernel module file is obtained by obj-m compilings.
Kernel compiling mode is changed as generation kernel module file xxx.ko, is needed open source protocol (GPL, the phase of linux
When in publicly-owned) proprietary protocol (proprietary) is revised as, it is compiled by obj-m and obtains kernel module file.
Under S202, the kernel module file copy to root file for generating compiling.
S203, the root file is packaged into image file, the root of the image file burning into terminal is literary
Part system.
The kernel module file xxx.ko for compiling generation is copied under a file for being root, this file meeting
Be packaged into an image file, burning into corresponding to root file system after handheld device, kernel module file xxx.ko corresponds to/
xxx.ko。
S204, assignment is carried out to the permission of the kernel module file, the permission for making the kernel module file be with
Executable permission.
After the kernel module file mount root file system for compiling generation, to the permission of kernel module file xxx.ko
(such as chmod 777/xxx.ko) carries out assignment, it is allowed to have executable permission.Kernel module file has a variety of authority credentials, example
Such as, 4 read right is represented, 2 write permissions, 1 execution permission, 7, which just represent read-write, performs permission, and 5 read to perform permission with regard to representing, with such
It pushes away.
S205, the loading kernel module file, create at least one device file.
By insmod/xxx.ko loading kernel modules, the module, such as range sensor, display screen etc. after loading successfully,
Registration can be driven and create a series of module device files for application operating.
S206, setting at least one device file permission be the required permission of application.
After loaded kernel module xxx.ko, it is that application is required to need to change the access rights such as the read-write of device file
Permission, such as chown system system/sys/class/motor/cameramotor/mdmode.
S207, the application is received according to described using access of the required permission at least one device file.
S208, the operation that corresponding function is carried out at least one device file.
After completing aforesaid operations, we can read sys/class/als_ps/ with access equipment file when such as making a phone call
Ps_raw, when value for 1 far from when bright screen, extinguish screen close to (as close to ear) when value is 0.
The setting method of device file permission in a kind of kernel module provided according to embodiments of the present invention generates compiling
Kernel module file copy to root file under, setting kernel module file permission be with executable permission, add
Kernel module file is carried, creates multiple equipment file, the permission for setting multiple device file is to apply required permission, so as to
