A Linux operating system for performing the device mount method of the present invention runs in a computing device, and fig. 1 shows a schematic diagram of a computing device 100 according to one embodiment of the present invention. It should be noted that the computing device 100 shown in fig. 1 is only an example, in practice, the computing device may be any type of device, the hardware configuration of the computing device may be the same as that of the computing device 100 shown in fig. 1, or may be different from that of the computing device 100 shown in fig. 1, and hardware components of the computing device 100 shown in fig. 1 may be added or deleted, and the specific hardware configuration of the computing device is not limited in the present invention.

The example processor core 114 may include an Arithmetic Logic Unit (ALU), a Floating Point Unit (FPU), a digital signal processing core (DSP core), or any combination thereof. The example memory controller 118 may be used with the processor 104, or in some implementations the memory controller 118 may be an internal part of the processor 104.
Depending on the desired configuration, system memory 106 may be any type of memory, including but not limited to: volatile memory (such as RAM), non-volatile memory (such as ROM, flash memory, etc.), or any combination thereof. The physical memory in the computing device is usually referred to as a volatile memory RAM, and data in the disk needs to be loaded into the physical memory to be read by the processor 104. System memory 106 may include an operating system 120, one or more applications 122, and program data 124. In some implementations, the application 122 can be arranged to execute instructions on an operating system with program data 124 by one or more processors 104.

When the application 122 is installed into the computing device 100, a driver module may be added to the operating system 120.
When the computing device 100 is started, the processor 104 reads program instructions of the operating system 120 from the memory 106 and executes them. The application 122 runs on top of the operating system 120, utilizing the operating system 120 and interfaces provided by the underlying hardware to implement various user-desired functions.

By way of non-limiting example, communication media may include wired media such as a wired network or private-wired network, and various wireless media such as acoustic, Radio Frequency (RF), microwave, Infrared (IR), or other wireless media. The term computer readable media as used herein may include both storage media and communication media.
In the computing device 100 according to the present invention, the operating system 120 includes instructions for performing the device mount method 200 of the present invention, enabling automatic mounting of the device.
The device auto-mount program may be implemented in a desktop taskbar application of an operating system, for example, in a UOS system, a desktop taskbar application of dde-dock, and the desktop taskbar application, for example, dde-dock plug-in may implement various applications according to user requirements, for example, a device mount (i.e., a device loader) is implemented by a dde-dock plug-in, fig. 2 shows a schematic diagram of a device mount system architecture 200 according to an embodiment of the present invention, which is suitable for executing the device mount method of the present invention and resides in a UOS operating system of a computing device.
As shown in fig. 2, a system kernel 210 in an operating system is adapted to detect insertion of a hardware device, when a device (e.g., a usb disk) is inserted, the system kernel 210 detects a change of the hardware device, a device manager udev 220 in the operating system sends detected device information to a Hardware Abstraction Layer (HAL) 230, the hardware abstraction layer 230 sends a first signal containing the device information to a system Bus, the system Bus is implemented by a D-Bus 240 Bus and completes inter-process communication, the system Bus further includes a udicks service 250 (i.e., a block device management interface), and encapsulates a Wrapper module Udisks2-Qt 5260 based on the service by using Qt, and issues the Wrapper module Udisks2-Qt 5260 in a shared library form to facilitate other application calls, and the Udisks2-Qt 5260 provides a Qt signal for other processes to listen and process.
The device loader 270 binds the QT signal issued by the Udisks2-QT5, executes the device-mounted program when the QT signal is detected by the process executing the device loader program, and notifies the taskbar manager 280 to display the newly inserted device (e.g., a usb disk) in the taskbar.
When the device mount 270 completes the device mount, a device mount completion signal is sent to the file manager 290, the file manager 290 is implemented by a boot daemon, and when the device mount completion signal is detected, the access control permission setting of the target device is completed.
The taskbar manager is a taskbar of an operating system, for example, a desktop taskbar application of a UOS operating system, which supports specific functions in the form of plug-ins, and the device loader is a plug-in of dde-dock.
FIG. 3 illustrates a flow diagram of a method 300 for device mounting, the method 300 adapted to be performed in a computing device (such as the computing device shown in FIG. 1) having a Linux operating system installed therein, the operating system including a taskbar manager including a device mount, a file manager, and a system bus including a block device management interface, according to one embodiment of the present invention.
As shown in fig. 3, the method 300 begins at step S310, where the block device management interface listens for a first signal from the system bus when the target device accesses.
According to an embodiment of the present invention, taking the device loading system architecture shown in fig. 2 as an example, when the system kernel detects the target device insertion, the device manager (udev) sends a target device insertion signal (first signal) to the Hardware Abstraction Layer (HAL), and the hardware abstraction layer sends the first signal ("interfacesadd" signal) to the D-Bus. The first signal includes an object path and hardware information of the target device, wherein the hardware information includes file system information, partition information, and encryption information of the device.
Subsequently, step S320 is entered, and the block device management interface sends the object path and the hardware information to the device loader via a second signal when determining that the target device is correctly identified according to the object path.
Continuing with the example of the device mounting system architecture shown in fig. 2, after detecting the first signal, the module udisks2-QT5 encapsulated based on udisks service (i.e., block device management interface) parses out the object path and hardware information therein and sends the object path and hardware information to the device mount via the second signal, where the second signal is a QT signal. Analyzing the object path and the hardware information in the first signal mainly comprises a data cleaning process and an object path conversion process.
The essence of data cleaning is to detect whether a D-Bus hardware information interface exists, file system information corresponds to org.freedesktop.udisks2.filesystem interface, the existence of the interface indicates that a device has a file system, and a hasfilesystechanged signal is converted during data cleaning, partition information corresponds to org.freedesktop.udisks2.partition interface, the existence of the interface information indicates that the inserted device has been partitioned, the partition information is converted into a hasPartitionChanged signal during data cleaning, encryption information corresponds to org.freedesktop.udisks2.encrypted interface, the existence of the interface indicates that the device is encrypted, and the encryption information is converted into an isenciphered signal during data cleaning.
The object path conversion comprises the steps of obtaining a prefix of an object path, generating path information as a device ID into a second signal if the prefix is/org/freedesktop/UDisks 2/drivers/, and converting the prefix of the object path into the form of the above/org/freedesktop/UDisks 2/drivers/to regenerate the second signal if the prefix is/org/freedesktop/UDisks 2/block _ devices/.
After data cleaning and object path conversion, the second signal includes hasFileSystemChange, hasPartitionChange, isEncrypteddchanged, and disakDeviceAdded signals. The second signal of QT type is more easily recognized and processed by the device loader.
Then, the process proceeds to step S330, and the device mounter mounts the target device according to the object path and the hardware information in the second signal.
According to the device mount system architecture shown in fig. 2, the device mount device binds the disaddevice added signal in the second signal, and when the signal is sent in step S320, executes a method corresponding to the slot function "DiskControlWidget:: onDriveConnected" bound in this step, so as to mount the usb disk, and when the mounting is completed, sends a device mount complete signal to the file manager, where the device mount complete signal includes the path information of the device (e.g., the usb disk) mount point.
Subsequently, step S340 is proceeded to, and when the file manager detects that the mount of the target device is completed, the access control authority of the target device is modified.
The file manager runs through the second daemon process, and in step S330, the device mount completion signal is sent after the device mount is completed, and when the second daemon process (i.e., the file manager) receives the device mount completion signal, the authority of the target device (the usb disk) can be modified, so that multi-user sharing is achieved.
For the Linux system, all accessed devices exist in the form of files, Linux divides the access user identities of the files into three categories, namely an owner, a user group and other users (owner/group/others), the file owner identity (owner) refers to the user in a plurality of users, the user group (group) refers to the user in a group which can divide the users into one group, the information of the user group is recorded in/etc/group, and the other person identity (others) refers to identities except the owner and the group. Because Linux provides a multi-user environment, the situation that a plurality of people use the host to work at the same time often occurs, and in order to consider the privacy of each person and the favorite work environment of each person, the permission of other users to all files of the user can be limited.
The three identities have the right of reading, writing and executing respectively. Read permission (read) means that the actual content of the file can be read, such as reading the text content of a text file; write rights (write) mean that the contents of the file can be edited, added, or modified (but not deleted); executable rights (execute) means that the file has rights that can be executed by the system. Whether a file has execution under Windows is judged by extension, for example: exe,. bat,. com, etc., but under Linux, whether our file can be executed is determined according to whether we have the authority of "x".
According to an embodiment of the invention, the file manager acquires the path information of the USB flash disk mounting point from the device mounting completion signal, and calls a system function "chmod" to give read, write and execute rights to other users (others). And the Linux command line can check the authority of each identity corresponding to each file through ls-l.
The authority limit of the file or directory is controlled by 9 authority limits, each three bits are a Group, which are read, write and execute by the file owner (User), read, write and execute by the User Group (Group) and read, write and execute by Other users (Other), respectively, as shown in fig. 4. The chmod command may specify permissions using binary numbers, for example: the read-write rights of file1 are modified by chmod 765 file1, where the sum of the three digits of the authority limit (rwx) of the owner is 7, i.e. 4+2+1, the sum of the sums of the digits of the authority limit (rw-) of the user group is 6, i.e. 4+2+0, and the sum of the sums of the digits of the authority limit (r-x) of the other users is 5, i.e. 4+0+ 1.
The file manager can release the read permission of other users to the newly inserted device (U disk), so that multi-user sharing is realized.
According to one implementation of the invention, the file manager runs through a startup process, monitors the file system from the start of system startup, and when a new directory is generated under the/home directory, it means that a new user is created, at this time, a directory corresponding to the user name under the/home directory is created under the/media, and is a path of the USB flash disk mounting point, and opens the read, write and execution permission of other users to read the path of the USB flash disk mounting point.
According to an embodiment of the invention, when discovering that a new user a is created, the file manager creates a directory/media/a under/media, gives other users the right to read, write and execute through the system call function chmod, and puts its access control limit open through setfacl command.
At present, the most applied U disk mounting technology is realized by setting a udev rule, a corresponding rule file needs to be created in a/etc/udev/rule.d', an execution script is created in a/sbin directory, and automatic mounting can be realized after restarting.
The various techniques described herein may be implemented in connection with hardware or software or, alternatively, with a combination of both. Thus, the methods and apparatus of the present invention, or certain aspects or portions thereof, may take the form of program code (i.e., instructions) embodied in tangible media, such as removable hard drives, U.S. disks, floppy disks, CD-ROMs, or any other machine-readable storage medium, wherein, when the program is loaded into and executed by a machine, such as a computer, the machine becomes an apparatus for practicing the invention.
