Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
In order to improve the efficiency of firmware upgrade, embodiments of the present invention provide a firmware upgrade method and apparatus.
First, a firmware upgrading method provided by an embodiment of the present invention is described below.
The firmware in the embodiment of the invention is a general name of software required for maintaining normal operation of the electronic equipment, basic components in the electronic equipment and pre-installed application programs. It should be noted that the software required for maintaining the normal operation of the electronic device is also often referred to as firmware by those skilled in the art, and for simplicity of description, the firmware, the basic components and the pre-installed applications referred to by those skilled in the art are collectively referred to as firmware in the embodiment of the present invention. Wherein, the basic component can be a component of basic function. For example, for a video camera, the base component may include a preview component within the camera. The pre-installed application program may be an app (application) program obtained by performing secondary development on the basic component to provide more intelligent services.
As known to those skilled in the art, according to the upgrade mode division, the firmware upgrade of the electronic device can be divided into an offline mode and an online mode. In order to clearly illustrate the technical solutions provided by the embodiments of the present invention, the offline mode and the online mode are briefly described.
The offline mode refers to a mode of firmware upgrade through a local area network. In the offline mode, the upgrade package of the target firmware provided by the device vendor needs to be downloaded and saved locally. For a general embedded device (such as a switch), since the memory space of the device is limited, the device cannot completely store the upgrade package of the target firmware, and therefore, the upgrade package is generally placed in the upgrade client in advance. And upgrading the firmware of the electronic equipment through the upgrading client.
Online mode refers to the way firmware is done over the internet. In the online mode, the electronic device needs to be connected with an upgrade server through the internet in advance, and sends a firmware upgrade request to the internet to upgrade the firmware.
For the embodiment of the invention, whether in an offline mode or an online mode, the firmware released by the equipment manufacturer exists in an upgraded package mode. For the upgrade package in the offline mode, the complete data file can be used, that is, each file in the upgrade package is a complete file. For the upgrade package in online mode, the upgrade includes an address connection where each file can be the file, which can relieve the storage pressure of the upgrade server.
The embodiment of the invention can be applied to various electronic devices, such as embedded devices such as switches, intelligent terminals, servers and other devices with data processing capability. Moreover, the firmware upgrading method provided by the embodiment of the invention can be realized in a software, hardware or combination of software and hardware.
In order to improve the efficiency of firmware upgrade, an embodiment of the present invention provides a firmware upgrade method, including:
acquiring a description file of an original firmware as a first description file; the description file is a preset file for recording the content attribute of each file in the firmware to which the description file belongs;
acquiring difference information determined by using the first description file and the second description file; wherein the second description file is: the original firmware is to be upgraded into a description file of the target firmware, and the difference information is used for indicating: target file identification and target upgrading operation of files with different contents between original firmware and target firmware;
and executing target upgrading operation by using the file indicated by the target file identification so as to upgrade the original firmware.
The above technical solution provided in the embodiment of the present invention may acquire the description file of the original firmware as the first description file, and acquire the difference information determined by using the first description file and the second description file of the target firmware, where the difference information indicates: and the target file identifier and the target upgrading operation of the file with the content difference between the original firmware and the target firmware are performed, and then the target upgrading operation is performed by using the file indicated by the target file identifier so as to upgrade the original firmware. Because the description file is a preset file for recording the content attribute of each file in the firmware to which the description file belongs, when the firmware needs to be upgraded, the difference information between the original firmware and the target firmware can be determined by using the first description file of the original firmware and the second description file of the target firmware, and binary difference does not need to be carried out on the files in the firmware, so that the firmware upgrading efficiency is improved.
The following describes a firmware upgrading method provided in an embodiment of the present invention with reference to the accompanying drawings.
As shown in fig. 1, a firmware upgrading method provided in an embodiment of the present invention is applied to an electronic device, where an original firmware to be upgraded is set in the electronic device, and the method may include the following steps:
s101, acquiring a description file of an original firmware as a first description file; the description file is a preset file for recording the content attribute of each file in the firmware to which the description file belongs;
the description file may be a JSON (JavaScript Object Notation) format file. The JSON file is a lightweight data exchange format file.
The content attribute may be a file identifier, location information, version information, hash value, file size, file type, etc. The file identifier may be a name of a file, etc. The location information may be an offset location of the file in the upgrade package, or an address link of the file. The version information may be a release version number of the file firmware. The hash value is obtained by performing hash value calculation on the file. The file size is the data size of the file. The file type is a type to which the file belongs, wherein the file type can be divided into a directory type and a non-directory type, which needs to be explained. The directory of the firmware is also used as a file in the upgrade package, and the non-directory type file is the actual content file of the firmware.
For example, in a description file of a specification, the following content attributes may be recorded: at least one of schema version, Component (file name), fileType, version, digest, offset, size, url, or signature.
Wherein the schema version is used for describing the specification version of the file. Layers are the content Layers of the files, including the specific content properties of the files. Component is the name of the file. Version is the Version of the file. The fileType is a file type and is divided into directory files and non-directory files (normal files), wherein the directory files may not have attributes such as file size, offset position, hash value, and the like. Digest is a file hash value, and can be obtained by calculating a file by using sha 256. Offset is the Offset of the file in the upgrade package. Size is the file Size of the file. Signature is Signature information of the file and is used for proving the legality of the file.
When the firmware needs to be upgraded, the electronic device can directly read the description file of the original estimation currently running by the electronic device from a cache or other memories.
S102, acquiring difference information determined by using the first description file and the second description file; wherein the second description file is: the original firmware is to be upgraded into a description file of the target firmware, and the difference information is used for indicating: target file identification and target upgrading operation of files with different contents between original firmware and target firmware;
in other words, the electronic device obtains the difference information in different manners in different scenes. For the offline mode, the electronic device itself may execute the difference information determined by using the first description file and the second description file, and the electronic device may acquire the difference information. And for the online mode, the upgrade server may execute the difference information determined by using the first description file and the second description file, and at this time, the electronic device may obtain the difference information from the upgrade server. A specific implementation manner of the difference information determined by using the first description file and the second description file will be described in embodiments required later, and is not described herein again.
For a file in the original firmware and a file in the target firmware, the file existence form may include four types: the first method comprises the following steps: the original firmware and the target firmware exist and are the same; and the second method comprises the following steps: the original firmware and the target firmware are different in content; and the third is that: present in the original firmware, but not in the target firmware; and fourthly: not in the original firmware but in the target firmware.
For the first form of presence, the file does not require any action to be taken, as it is present in both the original firmware and the target firmware. For the other three existing forms, the file is not completely consistent in the original firmware and the target firmware, that is, the file is a file with a difference in content between the original firmware and the target firmware, so that the file identifier of the file is a target file identifier, and the upgrade operation for the file is a target upgrade operation. The target upgrading operation is modification operation for the second existing form file, deletion operation for the third existing form file, and addition operation for the fourth existing form file.
And S103, executing target upgrading operation by using the file indicated by the target file identification so as to upgrade the original firmware.
As can be seen from the foregoing description, the target upgrade operation is: add operations, delete operations, or modify operations. If the target upgrading operation is an adding operation, acquiring a file with a target file identifier in the target firmware, and adding the acquired file into the original firmware; if the target upgrading operation is a deleting operation, deleting the file with the target file identification from the original firmware; and if the target upgrading operation is a modification operation, updating the file with the target file identification in the original firmware based on the file with the target file identification in the target firmware.
According to the technical scheme provided by the embodiment of the invention, because the description file is a preset file for recording the content attribute of each file in the firmware to which the description file belongs, when the firmware needs to be upgraded, the difference information between the original firmware and the target firmware can be determined by using the first description file of the original firmware and the second description file of the target firmware, and binary difference does not need to be carried out on the files in the firmware, so that the firmware upgrading efficiency is improved.
Optionally, in an embodiment, on the basis of the embodiment shown in fig. 1, as shown in fig. 2, an embodiment of the present invention further provides another firmware upgrading method, which includes, in addition to the steps shown in fig. 1:
s201: comparing the content attributes of the first description file and the second description file;
wherein, the content attribute of each file may include the version information and hash value to which the file belongs, and the content attribute comparison of the first description file and the second description file may include;
and comparing the version information of the file with the hash value of the first description file and the second description file.
The judging mode of whether any two content attributes are the same includes: if the contained version information and the hash value are the same, the two arbitrary content attributes are the same, otherwise, the two arbitrary content attributes are different.
S202: if the first content attribute only appearing in the first description file exists, determining the file identifier of the first file to which the first content attribute belongs as a target file identifier and the target upgrading operation as a deleting operation;
for example, the first description file includes content attribute 1, content attribute 2, and content attribute 3, and the second description file includes content attribute 2 and content attribute 3, so that content attribute 1 only appears in the first description file, and thus the file identifier of the first file to which content attribute 1 belongs is determined as the target file identifier and the target upgrade operation is the delete operation.
S203: if the second content attribute only appearing in the second description file exists, determining the file identifier of the second file to which the second content attribute belongs as a target file identifier and performing target upgrading operation as increasing operation;
for example, the first description file includes content attribute 1, content attribute 2, and content attribute 3, and the second description file includes content attribute 1, content attribute 2, content attribute 3, and content attribute 4, then content attribute 4 appears in the second description file only initially, so the file identifier of the second file to which content attribute 4 belongs is determined as the target file identifier and the target upgrade operation is the add operation.
S204: if the second description file has a fourth content attribute corresponding to the third content attribute, determining the file identifier of the third file to which the third content attribute belongs as a target file identifier and the target upgrading operation as a modifying operation; the third content attribute is a content attribute in the first description file, and the fourth content attribute is different from the third content attribute and belongs to the same file.
For example, if the first description file includes a content attribute 5, and the file identifier of the content attribute 5 is an identifier a, and the second description file includes a content attribute 6, and the file identifier of the content attribute 6 is also an identifier a, the content attribute 6 is a third content attribute, and the content attribute 5 is a fourth content attribute, the identifier a to which the content attribute 6 belongs is determined as a target file identifier, and the target upgrade operation is a modify operation.
In the above description, the electronic device is only used to execute the above steps as an example. When the electronic device is in an online scene, the execution main body of the steps can be an upgrade server, the electronic device only needs to send the first description file and version information pointing to the target firmware to be upgraded to the upgrade server, and the upgrade server obtains the second description file according to the version image so as to point to the content attribute comparison process. Since the comparison process is completely consistent with the steps shown in FIG. 2, the description is omitted.
According to the technical scheme provided by the embodiment of the invention, because the description file is a preset file for recording the content attribute of each file in the firmware to which the description file belongs, when the firmware needs to be upgraded, the difference information between the original firmware and the target firmware can be determined by using the first description file of the original firmware and the second description file of the target firmware, and binary difference does not need to be carried out on the files in the firmware, so that the firmware upgrading efficiency is improved.
In an embodiment, when the upgrade mode is an offline upgrade mode, the electronic device needs to first obtain a second description file of the target upgrade package, and at this time, before performing content attribute comparison between the first description file and the second description file, the method further includes:
acquiring header information of an upgrade package where target firmware is located; wherein the header information indicates location information of a second description file in the upgrade package; and acquiring a second description file from the upgrade package based on the position information.
The header information may be common fixed header information, so as to facilitate identification of the location and size of the description file during network transmission. The electronic device receives the header information of the upgrade package first, and then can know the position information of the second description file in the upgrade package based on the header information, for example, the header information is the offset and the size of the second description file in the upgrade package, and then can know the data interval occupied by the second description file in the upgrade package based on the offset and the size. And further sending a request containing offset and size to the upgrading client to request the upgrading client to send the description file.
According to the technical scheme provided by the embodiment of the invention, because the description file is a preset file for recording the content attribute of each file in the firmware to which the description file belongs, when the firmware needs to be upgraded, the difference information between the original firmware and the target firmware can be determined by using the first description file of the original firmware and the second description file of the target firmware, and binary difference does not need to be carried out on the files in the firmware, so that the firmware upgrading efficiency is improved.
Optionally, in an embodiment, the electronic device may be connected to the upgrade client through a local area network, and in this case, in an implementation manner, if the target upgrade operation is an add operation, a file with a target file identifier in the target firmware is obtained from the upgrade client, and the obtained file is added to the original firmware. In another implementation manner, if the target upgrade operation is a modification operation, a file with a target file identifier in the target firmware is acquired from the upgrade client, and the acquired file is used to replace the file with the target file identifier in the original firmware.
Optionally, in another embodiment, the electronic device is connected to an upgrade server through the internet, and in this case, in an implementation manner, if the target upgrade operation is an add operation, a file with a target file identifier in the target firmware is obtained from the upgrade server, and the obtained file is added to the original firmware; in another implementation mode, if the target upgrading operation is a modification operation, a target update file is obtained from an upgrading server, and the file with the target file identification in the original firmware is updated by using the target update file; and the target update file is obtained based on a file with a target file identification in the target firmware.
Optionally, in an embodiment, the target update file is: the step of updating the file with the target file identifier in the original firmware by using the target update file may include:
and replacing the file with the target file identification in the original firmware by using the file with the target file identification in the target firmware.
The target update file is a differential file obtained by binary differential of a file with a target file identifier in the original firmware and the file with the target file identifier in the target firmware by the upgrade server; in this case, the step of updating the file with the target file identifier in the original firmware by using the target update file may include: and adding the differential file into a file with the target file identification in the original firmware.
The binary difference is to compare the new file with the original file in binary, extract the difference part, and only update the difference part when upgrading the device, so as to save the flow and the upgrading time.
According to the technical scheme provided by the embodiment of the invention, because the description file is a preset file for recording the content attribute of each file in the firmware to which the description file belongs, when the firmware needs to be upgraded, the difference information between the original firmware and the target firmware can be determined by using the first description file of the original firmware and the second description file of the target firmware, and binary difference does not need to be carried out on the files in the firmware, so that the firmware upgrading efficiency is improved.
Optionally, in an embodiment, the difference information may be obtained from the upgrade server, and the difference information is further used to indicate: when the target upgrading operation is an increasing operation, a first download address of a file to be increased, or when the target upgrading operation is a modifying operation, a second download address of a target updating file; the file to be added is a file with a target file identifier;
at this time, the file with the target file identifier in the target firmware may be obtained from the upgrade server according to the first download address, and the target update file may be obtained from the upgrade server according to the second download address.
According to the technical scheme provided by the embodiment of the invention, because the description file is a preset file for recording the content attribute of each file in the firmware to which the description file belongs, when the firmware needs to be upgraded, the difference information between the original firmware and the target firmware can be determined by using the first description file of the original firmware and the second description file of the target firmware, and binary difference does not need to be carried out on the files in the firmware, so that the firmware upgrading efficiency is improved.
In order to more clearly illustrate the technical solutions of the embodiments of the present invention, the embodiments of the present invention are described below from an offline mode and an online mode, respectively.
As shown in fig. 3, which is a schematic structural diagram of an upgrade package in an offline mode, each firmware in the upgrade package is derived from a specified version of firmware stored in a warehouse and already in an internal release state, each firmware may be composed of one file or a plurality of files and directories (the directories are represented as files in the upgrade package), and the upgrade package is encrypted in units of files, so that malicious tampering of content can be prevented.
Furthermore, the upgrading process includes the steps of sorting the files and the directory names from small to large according to the character sequence of the files, and then forming a new binary file by connecting the encrypted binary data of the files according to the sorting sequence. Meanwhile, a description file, i.e., a file describing information of each upgrade file in fig. 3, is added to the header, and an encrypted header (referred to as header information in the foregoing) is added to the front of the description file.
When the electronic equipment is connected with the upgrading client through the local area network, the electronic equipment firstly receives the head information of the off-line upgrading packet, so that the offset and the size of the description file in the binary upgrading packet are known, and the offset and the size of the description file are fed back to the upgrading client. After the description file is obtained, the description file is analyzed, and version information and hash values of all files in the target firmware recorded in the description file are extracted.
If the directory does not exist in the electronic equipment, the directory needs to be created according to the information of the recorded target file in the description file, and for the ordinary file of the non-directory file, the version, the information and the hash value need to be compared with the corresponding file in the original firmware in the electronic equipment, so as to extract the file identifier, the offset and the size of the file with different version information and hash value, and feed back the file identifier, the offset and the size to the upgrade client, so that the upgrade client reads the data in the binary upgrade package according to the fed file identifier, the offset and the size and sends the data to the electronic equipment.
For the online mode, when the electronic device needs to upgrade the firmware, the electronic device first initiates a differential upgrade request to the upgrade server, and informs the upgrade server of the version of the original firmware running in the electronic device and the version of the target firmware that is expected to be upgraded. After receiving the request of differential upgrading, the upgrading server firstly obtains a first description file of the original firmware and a second description file of the target firmware, and then downloads files to which content attributes in the first description file and the second description file belong respectively.
Traversing the content attribute of each file in the first description file and the second description file, and if the file is a directory file, directly recording the content attribute into a new difference description file; if the new upgrade package exists and the old upgrade package does not exist, recording the difference description file and marking the difference description file as a new file; if the old upgrade package exists and the new upgrade package does not exist, recording the difference description file and marking the difference description file as a deleted file; if the new and old upgrade packages exist, comparing version information and hash values of the files, carrying out binary differential calculation under the condition that the version information or the hash values are different to obtain binary files of different parts, recording information of the produced differential files, including names, download addresses and the like, into a differential description file, and marking the differential description file as modified;
optionally, in an implementation manner, the differentiated content digest of each file is signed by a private key in the upgrade server, and the signature information is stored in the content digest of each file. After the electronic device obtains the difference description file, the electronic device verifies the signature information by using the corresponding public key, so that the source of the file is judged to be reliable and the file is not tampered.
And the upgrading server returns the difference description file to the electronic equipment. And the electronic equipment performs corresponding processing according to the difference description file returned by the upgrading server. If the directory file is yes, judging whether the directory file exists or not, and if not, creating a directory; otherwise, judging whether the file attribute is newly added, normally creating and writing the file if the file attribute is newly added, deleting the attribute, releasing the storage space of the original file of the equipment, modifying the attribute, and executing the patch to update the old file.
According to the technical scheme provided by the embodiment of the invention, because the description file is a preset file for recording the content attribute of each file in the firmware to which the description file belongs, when the firmware needs to be upgraded, the difference information between the original firmware and the target firmware can be determined by using the first description file of the original firmware and the second description file of the target firmware, and binary difference does not need to be carried out on the files in the firmware, so that the firmware upgrading efficiency is improved.
