[0002] In the prior art, there are two types of system service programs in the system. One type is a system service program that needs to perform inter-process communication (IPC) with an application (APP) all the time, such as a root server (RS) and a virtual file system (VFS). The other type is other system service programs that can dynamically choose whether to perform IPC communication with an application.

[0003] After the application is started, the application needs to dynamically create IPC resources and use the above IPC resources to establish an IPC channel between the application and the system service program through the IPC handle to achieve IPC communication between the application and the system service program. However, in the case where the applications opened by the system occupy a large number of IPC resources, when a new application is opened, the application needs to obtain the corresponding IPC resources to achieve IPC communication between the application and the above RS, VFS and other system service programs. However, due to the small number of IPC communication resources remaining in the system, it will be impossible to establish an IPC channel between the application and the above RS, VFS and other system service programs, which may lead to low reliability of IPC communication between the application and the above RS, VFS and other system service programs.

[0039] In order to more clearly understand the above-mentioned objectives, features and advantages of the present disclosure, the scheme of the present disclosure will be further described below. It should be noted that the embodiments of the present disclosure and the features in the embodiments can be combined with each other without conflict.

[0040] In the following description, many specific details are set forth to facilitate a full understanding of the present disclosure, but the present disclosure may also be implemented in other ways different from those described herein; it is obvious that the embodiments in the specification are only part of the embodiments of the present disclosure, rather than all of the embodiments.

[0041] In order to solve the problem in the prior art that the reliability of IPC communication between an application and a system service program such as RS and VFS that needs to communicate with the application all the time is low, the embodiments of the present application provide a communication method, device, equipment and vehicle. Since the IPC information obtained during the process of the system starting the target application includes the information created when the target system service program is started to establish an IPC channel between the target application and the target system service program, the above-mentioned IPC information can be subsequently transmitted to the target application to control the target application to directly use the IPC channel between the target application and the target system service program, thereby enabling the target application and the target system service program to communicate with each other through IPC. In this way, the IPC communication between the target application and the target system service program is realized, and the reliability of establishing IPC communication between the application and system service programs such as RS and VFS is also improved.

[0042] The communication method provided in the embodiment of the present application can be executed by a communication device or a control module in the communication device for executing the communication method. The communication method provided in the embodiment of the present application is described in detail by taking the communication device executing the communication method as an example.

[0043] The communication method provided in the embodiment of the present application is described in detail below through specific embodiments in conjunction with the accompanying drawings.

[0044] Figure 1 It is a flow chart of a communication method provided in an embodiment of the present application.

[0045] like Figure 1 As shown, the execution subject of the communication method may be a communication device, and the method may include the following steps:

[0046] S110, in the process of the system starting the target application, obtaining the inter-process communication IPC information corresponding to the target application.

[0047] In some embodiments, the IPC information involved above may include information created when the target system service program is started and used to establish an IPC channel between the target application and the target system service program. Specifically, the IPC information involved above may include IPC handle information and IPC resources. It should be noted that the IPC resources involved above may be related resources pre-allocated for starting the target application and required for the target application to communicate with the target system service program through IPC. In addition, the IPC resources involved above may be understood as IPC objects, and the IPC handle information involved above is used to access the related information of the IPC object.

[0048] The target system service program may be a related system service program that needs to perform IPC communication with the application program all the time, for example, the target system service program may be a system service program such as RS, VFS, etc., which is not limited here. In addition, the target application program mentioned above may be at least one application program among multiple applications running in the electronic device or system, which is not limited here.

[0049] Specifically, the communication device can obtain IPC information corresponding to the target application during the process of the system starting the target application, so that the target application can be controlled to use the IPC channel between the target application and the target system service program to enable the target application to perform IPC communication with the target system service program.

[0050] S120: delivering the IPC handle information to the target application.

[0051] Specifically, after acquiring the IPC information corresponding to the target application, since the IPC information includes the IPC handle information, based on this, the communication device can transmit the above IPC handle information to the target application.

[0052] S130, controlling the target application to use the IPC channel between the target application and the target system service program, so that the target application and the target system service program perform IPC communication.

[0053] In some embodiments, the IPC channels mentioned above are created based on IPC handle information and IPC resources.

[0054] Specifically, after the communication device passes the above-mentioned IPC handle information to the target application, since the IPC handle information can be relevant information for accessing IPC resources, and the IPC channel is created based on the IPC handle information and IPC resources, the communication device can control the target application to directly use the IPC channel between the target application and the target system service program, so that the target application and the target system service program can perform IPC communication.

[0055] In the embodiment of the present application, since the IPC information obtained during the process of the system starting the target application includes the information for establishing the IPC channel between the target application and the target system service program when the target system service program is started, the above-mentioned IPC information can be subsequently transmitted to the target application to control the target application to directly use the IPC channel between the target application and the target system service program, thereby enabling the target application and the target system service program to perform IPC communication. In this way, the IPC communication between the target application and the target system service program is realized, and the reliability of the IPC communication between the application and the system service programs such as RS and VFS is also improved.

[0056] In order to describe the communication method provided by the embodiment of the present application in more detail, in one embodiment, the above-mentioned steps of obtaining the IPC information between processes corresponding to the target application may specifically include the following steps:

[0057] From the multiple IPC handle information stored in the system internal variables, obtain the IPC handle information corresponding to the target application.

[0058] Specifically, the communication device can obtain the IPC handle information corresponding to the target application from the multiple IPC handle information stored in the system internal variables. The system internal variables can be data storage locations defined by the operating system. The multiple IPC handle information involved above corresponds one-to-one to multiple applications in the system.

[0059] In this embodiment, the communication device can obtain the IPC handle information corresponding to the target application from multiple IPC handle information stored in the system internal variables during the process of starting the target application, so that the IPC resources corresponding to the IPC handle information can be accessed by passing the IPC handle information to the target application, thereby facilitating the subsequent IPC communication between the target application and the target system service program.

[0060] Based on this, in order to more comprehensively describe the communication method provided by the embodiment of the present application, in one embodiment, before the above step of obtaining the IPC handle information corresponding to the target application from the multiple IPC handle information stored in the system internal variables, the above communication method may include the following steps:

[0061] In the process of starting the target system service program, IPC information corresponding to the multiple application programs is created;

[0062] The IPC handle information corresponding to the multiple applications is stored in the system internal variables.

[0063] Specifically, in the process of starting the target system service program, the communication device can create IPC information corresponding to multiple applications respectively. Since the IPC information can include IPC handle information, the communication device can store the IPC handle information corresponding to multiple applications respectively in the system internal variables, so that when a certain application is started later, the corresponding IPC handle information can be obtained from the system internal variables, thereby facilitating the subsequent realization of IPC communication between the target application and the target system service program. In this embodiment, it is possible to create IPC information corresponding to multiple applications in advance in the process of starting the target system service program, that is, to pre-establish IPC channels between multiple applications and the target system service program respectively, and store the above-created IPC information in the system internal variables. In this way, it is convenient to directly control the target application based on the corresponding IPC information in the process of starting the target application, and use the pre-established IPC channel between the target application and the target system service program to realize the IPC communication between the target application and the target system service program, thereby improving the reliability of the application and the system service programs such as RS and VFS to establish IPC communication.

[0064] In order to more accurately describe the communication method provided by the embodiment of the present application, in one embodiment, the above-mentioned step of transmitting the IPC handle information to the target application may specifically include the following steps:

[0065] Based on the preset delivery method, the IPC handle information is delivered to the target application through the preset interface. The preset delivery method may be a delivery method preset based on actual experience or circumstances, and is not limited here. The preset interface involved above may be a preset interface for delivering the IPC handle information to the target application.

[0066] Specifically, the communication device can transmit IPC handle information to the target application through a preset interface based on a preset transmission method. In this way, since the IPC handle information can be used to access the IPC resources corresponding to the IPC handle information, and the IPC channel is created based on the IPC handle information and the IPC resources, the target application can be controlled to use the IPC channel between the target application and the target system service program to realize IPC communication between the target application and the target system service program.

[0067] In this embodiment, the communication device can transmit IPC handle information to the target application through a preset transmission method and a preset interface, so that the target application can be subsequently controlled to use the IPC channel between the target application and the target system service program to establish IPC communication between the two, thereby improving the reliability of IPC communication between the application and system service programs such as RS and VFS that need to communicate with the application through IPC all the time.

[0068] Based on this, in one embodiment, the above-mentioned step of transmitting the IPC handle information to the target application through the preset interface based on the preset transmission method may specifically include the following steps:

[0069] Add the IPC handle information to the auxiliary vector list corresponding to the target application;

[0070] In the process of running the target application, the IPC handle information is obtained by parsing the auxiliary vector list corresponding to the target application, and the IPC handle information is transmitted to the target application through the first preset interface.

[0071] Specifically, the communication device may add the acquired IPC handle information to the auxiliary vector list corresponding to the target application, and parse the auxiliary vector list corresponding to the target application during the running phase of the target application to obtain the IPC handle information, and then transmit the IPC handle information through the first preset interface. Figure 2 As shown, taking RS and VFS system service programs as an example, IPC handle information is transmitted to the application program through the transmission method of the auxiliary vector list.

[0072] The auxiliary vector list is implemented by storing specially formatted structures on the process stack. These structures are stored in the form of key-value pairs and terminated by a zero-terminated end marker. Each key-value pair consists of an integer key (indicating the type of specific information) and an unsigned long integer value (indicating the data associated with the information). In an example, the auxiliary vector list involved above can be shown in Table 1:

[0073] Table 1 Auxiliary vector list

[0074] parameter Parameter meaning AT_NULL Used to indicate the end of the auxiliary vector list AT_PHDR Points to the address of the program header table in the process's executable file AT_ENTRY Points to the address of the process's entry point function AT_EXECFD File descriptor pointing to the process executable file AT_UID The user ID of the process AT_EUID The effective user ID of the process AT_GID The group ID of the process AT_EGID The effective group ID of the process AT_PLATFORM A string pointing to the name of the operating system or hardware platform AT_SECURE If set to a non-zero value, it means that the process is running in a secure environment.

[0075] It should also be noted that, in one example, the first preset interface involved above can be the interface task_append_aux(), in which the user APP Task handle, the user APP AUXV data type and the user APP AUXV data value are defined. Among them, the user APP Task handle is the task handle of the user APP in RS (used to manage user APP tasks and corresponding resources); the user APP AUXV data type is the user APP AUXV data type, and the corresponding AUXV data type needs to be used when passing RS and VFS communication IPC handles; the user APP AUXV data value is used to pass the RS and VFS communication IPC handles, and the handle value mapped to the user APP memory space needs to be passed.

[0076] In this embodiment, the IPC handle information can be delivered to the target application through the internal delivery mechanism corresponding to the target application, avoiding the situation where the delivered IPC handle information cannot be used, thereby facilitating the subsequent communication between the target application and the target system service program, and improving the reliability of IPC communication between the application and the system service programs such as RS and VFS that need to always communicate with the application through IPC. In addition, the auxiliary vector list involved above can be allocated when the process is loaded, and its storage area is fixed and does not change during the process operation, which can reduce the complexity of IPC handle information management and use a simple interface to obtain the corresponding IPC handle information.

[0077] In another embodiment, the above-mentioned step of transmitting the IPC handle information to the target application through the preset interface based on the preset transmission mode may include the following steps:

[0078] Parse the IPC handle information and obtain the IPC handle string;

[0079] Add the storage address corresponding to the IPC handle string to the IPC handle address table corresponding to the target application;

[0080] During the process of running the target application, the storage address corresponding to the IPC handle string is obtained by parsing the IPC handle address table corresponding to the target application, and the IPC handle information is obtained based on the storage address corresponding to the IPC handle string, and the IPC handle information is passed to the target application through the second interface.

[0081] Specifically, after the communication device obtains the IPC information corresponding to the target application, since the IPC information may include IPC handle information, based on this, the communication device can parse the IPC handle information to obtain the IPC handle string corresponding to the IPC handle information, and then add the storage address corresponding to the IPC handle string to the IPC handle address table corresponding to the target application. In this way, in the process of running the target application, the storage address corresponding to the IPC handle string can be obtained by parsing the IPC handle address table corresponding to the target application, and then the IPC handle string can be obtained by querying the storage address corresponding to the IPC handle string, and then the IPC handle information can be obtained based on the IPC handle string. Based on this, the communication device can pass the IPC handle information to the target application through the second preset interface. For example, if Figure 3 As shown, taking RS and VFS system service programs as an example, IPC handle information is transmitted to the application program through the transmission method of IPC handle character string.

[0082] The second preset interface mentioned above may be the interface task_append_ipc_hdl_str(task, name, val), where task is the task handle of the user APP in RS (used to manage the user APP tasks and corresponding resources); name corresponds to the IPC handle name in string format; and val is the corresponding IPC handle value.

[0083] In this embodiment, the IPC handle information can be delivered to the target application through an internal delivery mechanism corresponding to the target application, thereby avoiding the situation where the delivered IPC handle information cannot be used, thereby facilitating the subsequent communication between the target application and the target system service program, and improving the reliability of IPC communication between the application and system service programs such as RS and VFS that need to conduct IPC communication with the application all the time.

[0084] In order to more accurately and comprehensively describe the communication method provided by the embodiment of the present application, in one embodiment, the above-mentioned IPC handle information may include an IPC handle name and an IPC handle value;

[0085] The above-mentioned steps of parsing the IPC handle information and obtaining the IPC handle string may specifically include the following steps:

[0086] The IPC handle string is obtained by concatenating the IPC handle name and the IPC handle value.

[0087] In one example, the IPC handle string may be "RS_IPC_HANDLE=0xXXXX", "VFS_IPC_HANDLE=0xXXXX", where "RS_IPC_HANDLE" is the IPC handle name corresponding to RS, "VFS_IPC_HANDLE" is the IPC handle name corresponding to VFS, and "0xXXXX" is the string of the corresponding handle in hexadecimal.

[0088] In this embodiment, the communication device can obtain an IPC handle string based on the IPC handle name and IPC handle value included in the IPC handle information, so that the IPC handle information can be subsequently delivered to the target application through an internal delivery mechanism corresponding to the target application, thereby avoiding the situation where the delivered IPC handle information cannot be used.

[0089] In addition, it should be noted that after the communication device passes the IPC handle information to the target application through the above-mentioned first preset interface or the second preset interface, the target application can obtain the corresponding IPC handle information based on the calling interface get_ep_rs() and get_ep_vfs(). It should also be noted that if the target application receives unsigned longget_ep_rs(void) and the feedback return value is the RS IPC handle value, it indicates that the IPC handle information is successfully obtained. If the feedback return value is (unsigned long)-1, it indicates that the IPC handle information fails to be obtained. If the target application receives unsigned long get_ep_vfs(void) through the interface and the feedback return value is the VFS IPC handle value, it indicates that the IPC handle information is successfully obtained. If the feedback return value is (unsigned long)-1, it indicates that the IPC handle information fails to be obtained.

[0090] Based on the same inventive concept, the present application embodiment also provides a communication device, which can be specifically combined with Figure 4 The communication device provided in the embodiment of the present application is described in detail.

[0091] Figure 4 It is a structural diagram of a communication device provided in an embodiment of the present application.

[0092] like Figure 4 As shown, the communication device 400 may include: an acquisition module 410 , a transmission module 420 and a control module 430 .

[0093] The acquisition module 410 is used to acquire the inter-process communication IPC information corresponding to the target application during the process of the system starting the target application, the IPC information includes the information for establishing the IPC channel between the target application and the target system service program when starting the target system service program, and the IPC information includes the IPC handle information and the IPC resource;

[0094] A transfer module 420, used for transferring IPC handle information to a target application;

[0095] The control module 430 is used to control the target application to use the IPC channel between the target application and the target system service program so that the target application and the target system service program perform IPC communication. The IPC channel is created based on the IPC handle information and the IPC resources.

[0096] In one embodiment,

[0097] The acquisition module mentioned above is used to acquire the IPC handle information corresponding to the target application from the multiple IPC handle information stored in the system internal variables.

[0098] In one embodiment, the above-mentioned communication device may further include a creation module and a storage module.

[0099] A creation module, used for creating IPC information corresponding to a plurality of applications respectively in the process of starting the target system service program before acquiring the IPC handle information corresponding to the target application from the plurality of IPC handle information stored in the system internal variables;

[0100] The storage module is used to store the IPC handle information corresponding to multiple application programs into system internal variables.

[0101] In one embodiment, the transfer module mentioned above is used to transfer the IPC handle information to the target application through a preset interface based on a preset transfer method.

[0102] In one embodiment, the above-mentioned transfer module is specifically used for:

[0103] Add the IPC handle information to the auxiliary vector list corresponding to the target application;

[0104] In the process of running the target application, the IPC handle information is obtained by parsing the auxiliary vector list corresponding to the target application, and the IPC handle information is transmitted to the target application through the first preset interface.

[0105] In one embodiment, the above-mentioned transmission module is specifically used for:

[0106] Parse the IPC handle information and obtain the IPC handle string;

[0107] Add the storage address corresponding to the IPC handle string to the IPC handle address table corresponding to the target application;

[0108] During the process of running the target application, the storage address corresponding to the IPC handle string is obtained by parsing the IPC handle address table corresponding to the target application, and the IPC handle information is obtained based on the storage address corresponding to the IPC handle string, and the IPC handle information is passed to the target application through a second preset interface.

[0109] In one embodiment, the IPC handle information includes an IPC handle name and an IPC handle value; the above-mentioned communication device may also include a splicing module.

[0110] The splicing module is used to obtain an IPC handle string by splicing the IPC handle name and the IPC handle value.

[0111] In the embodiment of the present application, since the IPC information obtained during the process of the system starting the target application includes the information for establishing the IPC channel between the target application and the target system service program when the target system service program is started, the above-mentioned IPC information can be subsequently transmitted to the target application to control the target application to directly use the IPC channel between the target application and the target system service program, thereby enabling the target application and the target system service program to perform IPC communication. In this way, the IPC communication between the target application and the target system service program is realized, and the reliability of the IPC communication between the application and the system service programs such as RS and VFS is also improved.
