For example, the computer terminal 10 may also include more or fewer components than shown in FIG. 1, or have a different configuration than shown in FIG. 1.

It should be noted that the one or more processors and/or other data processing circuitry described above may be referred to generally herein as "data processing circuitry". The data processing circuitry may be embodied in whole or in part in software, hardware, firmware, or any combination thereof. Further, the data processing circuit may be a single stand-alone processing module, or incorporated in whole or in part into any of the other elements in the computer terminal 10 (or mobile device).

Under the above operating environment, the present application provides a processing method of the user mode program as shown in fig. 2. Fig. 2 is a flowchart of a processing method of a user mode program according to a first embodiment of the present invention.

Step S201, the user mode program obtains a file descriptor of the host side through the first communication module and the second communication module, where the file descriptor of the host side is an identifier corresponding to a kernel mode function module that the user mode program needs to call.

Specifically, in order to enable the user mode program to normally call the kernel mode function module, first, a first communication module and a second communication module are respectively arranged on the host and the uninstall card. A plurality of kernel mode functional modules are included on the host, and a plurality of user mode programs are included on the offload card. Each user mode program needs to obtain a file descriptor of the host side corresponding to the kernel mode functional module needing to be called through the first communication module and the second communication module. It should be noted that one user mode program may need to call the operation of the plurality of kernel mode function modules practice the service. For example, the host comprises a kernel mode functional module 1, a kernel mode functional module 2, a kernel mode functional module 3 and a kernel mode functional module 4; the uninstalling card comprises a user mode program 1 and a user mode program 2. The user mode program 1 needs to call the kernel mode functional module 1 and the kernel mode functional module 2 to realize service operation, and then the user mode program 1 acquires the host side file descriptor 1 and the host side file descriptor 2 corresponding to the kernel mode functional module 1 and the kernel mode functional module 2 through the first communication module and the second communication module. The operation of the kernel mode function module is realized through a file descriptor (fd) on the host side.

Step S202, the user mode program constructs a local file descriptor through the second communication module, and constructs a mapping relation between the local file descriptor and a file descriptor on the host side.

Specifically, after the user mode program acquires the fd of the host side, a local fd is constructed through the second communication module, and a one-to-one correspondence relationship between the fd of the host side and the local fd is constructed. For example, the user mode program 1 acquires the fd1 on the host side and the fd2 on the host side, and the communication module constructs the local fd1 and the local fd 2. The mapping relationship is constructed such that the local fd1 corresponds to the fd1 of the host side, and the local fd2 corresponds to the fd2 of the host side.

In step S203, the user mode program calls the kernel mode function module through the local file descriptor and the file descriptor on the host side, so that the user mode program responds to the ioctl request.

Specifically, the user mode program accurately calls the corresponding kernel mode function module through the fd of the host side and the local fd to realize service operation, that is, to complete an ioctl request.

In summary, by associating the fd of the host side with the local fd through the communication module, the user mode program can call the kernel mode function module to complete the service operation, and the rewriting of the call interface information is avoided, thereby solving the technical problem of low efficiency caused by the adoption of the syscall remote proxy mode to realize the normal service operation of the user mode program.

Optionally, in the processing method of the user mode program provided in the first embodiment of the present invention, before the user mode program obtains the file descriptor on the host side through the first communication module and the second communication module, the method further includes: and processing the first communication module and the second communication module so as to realize mutual identification of the first communication module and the second communication module.

Specifically, before the user mode program obtains the file descriptor on the host side, the first communication module and the second communication module need to be processed, so that the first communication module and the second communication module are identified with each other. Only if the first communication module and the second communication module are mutually identified, the user mode program can accurately obtain the file descriptor of the host side through the communication module.

Optionally, in the processing method of the user mode program provided in the first embodiment of the present invention, processing the first communication module and the second communication module to enable the first communication module and the second communication module to implement mutual identification includes: the user mode program controls the second communication module to generate a shared key verification code corresponding to the user mode program; sending the shared key verification code to a first communication module, wherein a target proxy process corresponding to the shared key verification code is generated in the first communication module, and a first identifier is returned to a second communication module, the target proxy process is used for realizing that a user mode program calls a kernel mode function module, and the first identifier represents that the first communication module generates the target proxy process; and under the condition that the second communication module receives the first identifier, the first communication module and the second communication module are confirmed to realize mutual identification.

Specifically, the mutual identification of the first communication module and the second communication module includes: the user mode program controls the second communication module to generate a shared key verification code (or a shared key) corresponding to the user mode program, and sends the shared key to the first communication module, the first communication module generates a corresponding target agent process according to the received shared key, and then the first communication module sends an identifier (namely the first identifier) of the generated target agent process to the second communication module. And the second communication module receives the identification, and indicates that the two communication modules finish mutual identification. Through the steps, mutual identification between the first communication module and the second communication module is realized, and preparation is made for accurately acquiring the file descriptor of the host side subsequently.

Optionally, in the processing method of the user mode program provided in the first embodiment of the present invention, before the user mode program obtains the file descriptor on the host side through the first communication module and the second communication module, the method further includes: and registering the kernel mode functional module in the first communication module to obtain a file descriptor of the host side corresponding to the kernel mode functional module.

Specifically, each kernel mode functional module needs to perform registration work in the first communication module, so that a subsequent user mode program can obtain a descriptor of the host side corresponding to the kernel mode functional module through the first communication module.

Optionally, in the processing method of the user mode program provided in the first embodiment of the present invention, the obtaining, by the user mode program through the first communication module and the second communication module, the file descriptor of the host side includes: the user mode program controls the second communication module to send a second identifier to the first communication module, wherein under the condition that the first communication module receives the second identifier, a file descriptor of the host side corresponding to the kernel mode functional module which needs to be called by the user mode program is returned to the second communication module; a file descriptor on a host side is received.

Specifically, the user mode program sends a second identifier to the first communication module through the second communication module, and after receiving the second identifier, the second communication module returns the file descriptor of the host side corresponding to the kernel mode function module, which needs to be called by the user mode program, to the second communication module. Through the steps, the user mode program can accurately obtain the file descriptor of the host side.

Optionally, in the processing method of the user mode program provided in the first embodiment of the present invention, the calling, by the user mode program, the kernel mode function module through the local file descriptor and the file descriptor on the host side, so that the user mode program responds to the ioctl request, includes: the user mode program sends an ioctl request to a local file descriptor; the local file descriptor responds to the ioctl request, and encapsulates the ioctl request into a command identifier in a preset format; the second communication module sends the command identifier to the first communication module, wherein the command identifier is analyzed into a starting instruction through a target proxy process generated by the first communication module, the starting instruction is sent to a file descriptor on the host side, and the target proxy process is used for realizing that a user mode program calls a kernel mode function module; and starting the kernel mode functional module by the file descriptor of the host side according to the starting instruction so that the user mode program calls the kernel mode functional module to complete the ioctl request.

Specifically, the step of the user mode program calling a corresponding kernel mode functional module to respond to the ioctl request through the local file descriptor and the file descriptor on the host side includes: firstly, a user mode program sends a request for executing a task (namely, the ioctl request) to a local file descriptor, the local descriptor encapsulates the request for executing the task into a command identifier with a preset format, a second communication module sends the command identifier to a first communication module, the first communication module immediately resolves the command identifier into a starting instruction after receiving the command identifier and sends the starting instruction to a file descriptor at a host side, and the file descriptor at the host side starts a corresponding kernel mode function module, so that the user mode program can call the kernel mode function module to complete service operation. Through the steps, the user mode program can call the kernel mode functional module only by sending a request for executing the task.

Optionally, in the processing method of the user mode program provided in the first embodiment of the present invention, after the user mode program calls the kernel mode function module through the local file descriptor and the file descriptor on the host side, so that the user mode program responds to the ioctl request, the method further includes: the second communication module monitors the state of the user mode program; if the user mode program is in the state of completing the ioctl request, the second communication module sends a third identifier to the first communication module, wherein the third identifier represents that the user mode program has completed the service operation, and under the condition that the first communication module receives the third identifier, a closing instruction is sent to a file descriptor of the host side; and the file descriptor of the host side closes the kernel mode functional module according to the closing instruction.

Specifically, the second communication module monitors the state of the user mode program, and when the second communication module monitors that the user mode program is in a state of completing an ioctl request, that is, a state of completing service execution, the second communication module sends a third identifier to the first communication module, the first communication module sends a close instruction to the file descriptor on the host side, and the file descriptor on the host side closes the corresponding kernel mode function module. And after the user mode program completes the service, the corresponding kernel mode functional module is closed in time, so that the kernel mode functional module is prevented from being in a standby state for a long time, and the problem of unnecessary resource waste is reduced.

In summary, in the processing method of the user mode program provided in the first embodiment of the present invention, the user mode program obtains the file descriptor of the host side through the first communication module and the second communication module, where the file descriptor of the host side is an identifier corresponding to a kernel mode function module that the user mode program needs to call; the user mode program constructs a local file descriptor through the second communication module and constructs a mapping relation between the local file descriptor and a file descriptor at the host side; the user mode program calls the kernel mode functional module through the local file descriptor and the file descriptor on the host side so that the user mode program responds to the ioctl request, and the technical problem of low efficiency caused by the fact that the service normal operation of the user mode program is achieved in a syscall remote proxy mode is solved. Through the two communication modules, the file descriptor at the host side is associated with the local file descriptor, so that a user mode program can call the kernel mode functional module to complete service operation, the calling interface information is prevented from being rewritten, and the problem of improving efficiency is further solved.
