It should be understood that, the information extraction is performed on the plug-in modification events, and the obtaining of the plug-ins to be loaded may be to traverse the plug-in modification events one by one, obtain a traversal result, and determine the plug-ins to be loaded according to the traversal result.

In the second embodiment, the step S30 includes:

step S301: and when the plug-in loading type is the replacing function loading type, determining a plug-in to be replaced and a target function according to the plug-in to be loaded.

It should be understood that, the determining of the plug-in to be loaded and the target function according to the plug-in to be loaded may be to extract information of the plug-in to be loaded, and obtain the plug-in to be replaced and the target function.

Step S302: and acquiring initial function information of the plug-in to be loaded, and determining an initial function inlet according to the initial function information.

It is to be understood that the determining of the initial function entry according to the initial function information may be looking up the initial function entry corresponding to the initial function information in a preset function information table. The preset function information table includes a corresponding relationship between the initial function information and the initial function entry, and the corresponding relationship between the initial function information and the initial function entry may be preset by a user.

Step S303: and searching a near jump instruction corresponding to the initial function inlet, and jumping to a target memory space address according to the near jump instruction.

It should be understood that, in the plug-in loading method of this embodiment, based on the inline hook technology, the first instruction at the entry of the initial function is modified to be the near jump instruction, and the program jumps to the memory space address storing the far jump instruction, so that when the program is executed to the initial function, the program jumps to the actual original jump instruction, and then jumps to the entry of the target function for execution. Because the far jump usually needs a plurality of instructions to realize, through the technology of the scheme, only one instruction of the initial function needs to be modified to carry out the jump twice, when the program is executed to the entry of the initial function, the jump is directly executed without suspending the process, and the hook failure condition caused by the halt failure is avoided.

It can be understood that if a remote jump instruction is used to jump when a program is executed to an entry of an initial function, a great change needs to be made to the initial function, for example, 5 instructions of the initial function may need to be changed, but such a great change to the initial function may result in complex function repair and difficult maintenance. In the scheme, when the program is executed to the initial function entrance, the near jump instruction corresponding to the initial function entrance is determined, the far jump instruction is not set at the initial function entrance, and only 1 instruction needs to be changed when the near jump instruction is set at the initial function, so that the change of the initial function is reduced, the difficulty of function repair is reduced, and the maintenance is more convenient.

Further, in consideration of practical application, a near jump instruction corresponding to the initial function entry is directly searched, and a target memory space address is jumped to according to the near jump instruction, which inevitably results in excessive objects involved in a processing process and excessive computation. To overcome this drawback, step S303 includes:

It should be noted that, the correspondence between the function entry and the close jump instruction may be preset by a user, which is not limited in this embodiment.

The preset second mapping relation table includes a corresponding relation between the near jump instruction and the target memory space address, wherein the corresponding relation between the near jump instruction and the target memory space address may be preset by a user.

Further, in order to improve the reliability of the first mapping relation table, before the preset first mapping relation table includes a corresponding relation between a function entry and a near jump instruction, the method further includes:

It should be understood that, because a far jump instruction needs to modify a plurality of instructions of a function, and a near jump instruction only needs to modify one instruction of the function, in order to achieve a better jump effect and improve the jump effect, the first instruction of the function entry to be selected may be modified to obtain the near jump instruction to be selected.

It can be understood that, according to the above steps, a candidate near jump instruction may be set for each candidate function entry of the candidate function, and the candidate function entry and the candidate near jump instruction have a corresponding relationship, and in order to more conveniently record the corresponding relationship therebetween and facilitate subsequent execution, a preset first mapping relationship table may be established according to the candidate function entry and the candidate near jump instruction. The corresponding relation between the function entry to be selected and the near jump instruction to be selected is recorded in the preset first mapping relation table.

Further, in order to avoid that a plurality of near jump instructions jump to the same far jump instruction, which results in slow program progress, different corresponding far jump instructions may be set for the near jump instructions of different initial functions, so as to achieve a better jump effect, the searching for a target memory space address corresponding to the near jump instruction in a preset second mapping relation table, and jumping to a position before the target memory space address, further includes:

It should be understood that after the to-be-selected near jump instruction is obtained, a corresponding to-be-selected memory space address may be allocated to each to-be-selected near jump instruction, and then a preset second mapping list may be established according to the to-be-selected near jump instruction and the to-be-selected memory space address. And the preset second mapping list records the corresponding relation between the to-be-selected near jump instruction and the to-be-selected memory space address.

It can be understood that each to-be-selected memory space address stores a to-be-selected far jump instruction, when jumping to the to-be-selected memory space address, the to-be-selected far jump instruction stored therein can be acquired, and far jump is performed through the to-be-selected far jump instruction.

Step S304: and acquiring a far jump instruction stored in the target memory space address, and jumping to a space address corresponding to a target function according to the far jump instruction.

It can be understood that, since the far jump instruction is stored in the target memory space address, the far jump instruction stored in the target memory space address can be acquired after jumping to the target memory space address according to the near jump instruction.

It should be appreciated that after the far jump instruction is fetched, the far jump instruction may be executed to jump to the spatial address corresponding to the target function. Through the steps, a far jump instruction does not need to be arranged at the entrance of the target function, but only a near jump instruction needs to be arranged at the entrance of the target function, and the far jump is realized through a mode of two jumps.

In a second embodiment, when the plug-in loading type is a replacement function loading type, determining a plug-in to be replaced and a target function according to the plug-in to be loaded, acquiring initial function information of the plug-in to be loaded, determining an initial function entry according to the initial function information, searching a near jump instruction corresponding to the initial function entry, jumping to a target memory space address according to the near jump instruction, acquiring a far jump instruction stored in the target memory space address, and jumping to a space address corresponding to the target function according to the far jump instruction, so that far jump in a hook process can be realized in a two-jump manner, and replacement function loading of the plug-in to be loaded is realized.
