Detailed Description

The technical solutions of the present invention will be described clearly and completely with reference to the following embodiments, and it should be understood that the described embodiments are some, but not all, embodiments of the present invention. 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.

Compared with upgrading the whole kernel, the kernel hot patch has the main advantage that the defects of the kernel and the kernel module can be repaired under the condition of not restarting the kernel and the service. The current tool for making the hot patch is mainly kpatch, the kpatch is open source software which is released by an open source community and can freely acquire tool source codes, a kernel hot patch file is generated by the kpatch tool according to a patch file for repairing codes, the generated hot patch file can be in an ELF (Executable and Linkable Format) Format, is usually named after a 'ko' suffix and can be directly installed in a kernel through a script of the kpatch tool so that the hot patch file takes effect.

The install hot patch command may refer to the following example:

kpatch load patch_1.ko

kpatch load patch_2.ko

the unload hot patch command may refer to the following example:

kpatch unload patch_2.ko

kpatch unload patch_1.ko

in the related art, in the process of using a manufactured hot patch, there are usually more use limitations due to different problems repaired by the hot patch, for example, the dependency relationship between the hot patch and the sequence of other software packages, the mutual exclusion relationship between a new version hot patch and an old version hot patch, and the like, and the hot patch strongly depends on the kernel version and can only be installed in a matched kernel, otherwise, the software is faulty or a major fault is caused. Therefore, when the hot patch is used to repair a problem, attention needs to be paid to the sequence, the dependency relationship, the mutual exclusion relationship, and the like between the hot patch and other software packages, and the installation, the use, the uninstallation, and the version management need to be operated by using a special script provided by a kpatch tool. Administrators need to be familiar with the actual functionality and implementation details of the hot patch in order to properly use kernel hot patches.

However, at present, development and production of a hot patch are mainly completed by research and development personnel, and operation and maintenance of the hot patch are mainly completed by professional operation and maintenance personnel, but the operation and maintenance personnel are unfamiliar with hot patch principles and production details, and do not know the interrelationship between the hot patch and other software packages, so that the correctness of related operations executed when the hot patch is used is difficult to ensure, thereby bringing greater risks to operation and maintenance work, and even causing major faults if the operation is improper.

Based on this, the embodiment of the invention provides a method and a device for operating a hot patch and an electronic device, and the technology can be applied to devices such as a mobile terminal and a computer, and especially can be applied to a scene needing the hot patch.

In order to facilitate understanding of the embodiment, first, a detailed description is given to an operation method of a hot patch disclosed in the embodiment of the present invention; as shown in fig. 1, the method comprises the steps of:

step S102, obtaining a hot patch file package; wherein, the hot patch file package includes: the hot patch file and a configuration file corresponding to the hot patch file; the configuration file includes: the method comprises the following steps of running kernel environment configuration information, operating system environment configuration information and running operation information of the hot patch file, wherein the kernel environment configuration information, the operating system environment configuration information and the running operation information are required by the hot patch file.

The hot patch file can also be called kernel hot patch, and can be understood as a program package which can be used for repairing defects of a kernel or a kernel module; the kernel environment configuration information generally includes conditions that need to be met by the kernel environment in order to ensure that the hot patch file can be correctly loaded to the kernel, for example, if the hot patch file needs to depend on other software packages to be correctly used, it is necessary to ensure that the kernel environment has the other software packages that depend on the hot patch file, and if the hot patch file does not depend on other software packages, it may need to download, install, and load the other software packages that depend on the hot patch file; the operating system environment configuration information generally includes conditions that need to be met by the operating system environment to ensure that the hot patch file can be correctly loaded to the kernel, for example, if the hot patch file needs to depend on some application packages or tool packages to be correctly loaded or run, it is necessary to ensure that the dependent application packages or tool packages exist in the operating system environment, and if the hot patch file does not exist, the dependent application packages or tool packages may need to be downloaded or installed, and the like; the operation information usually includes related operation steps, operation commands and the like required for loading the hot patch file into the kernel, and also includes related operation steps, operation commands and the like required for unloading the hot patch file from the kernel; in actual implementation, the manufactured hot patch file and the configuration file corresponding to the hot patch file may be packaged into a hot patch file package in advance, and when the hot patch file needs to be run, the hot patch file package generally needs to be obtained first. It should be noted that for some complex operations, a form of a script file may be adopted, that is, the hot patch package may further include a script file, and some relevant operation contents when the hot patch file is running are encapsulated in the script file, for example, before the hot patch file is installed in the kernel, an actual symbol address of a symbol that needs to be relocated is first queried, and when the hot patch file is modified, the symbol address is modified, and these two operation contents may be encapsulated in the script.

Step S104, determining that the current kernel environment conforms to the kernel environment configuration information required by the hot patch file, and the current operating system environment conforms to the operating system environment configuration information required by the hot patch file.

The current kernel environment can be understood as a kernel with a certain defect, and the kernel with the defect needs to be repaired by using a hot patch file; in actual implementation, after the hot patch file package is obtained, before the hot patch file is loaded to the current kernel, it is usually required to determine whether the current kernel environment conforms to the kernel environment configuration information required by the hot patch file and whether the current operating system environment conforms to the operating system environment configuration information required by the hot patch file and the configuration file, for example, if the hot patch file needs to be loaded correctly depending on other software packages, it may be determined whether other software packages that the hot patch file needs to depend on exist in the current kernel environment, and if other software packages that the hot patch file depends on exist, it may be determined that the current kernel environment conforms to the kernel environment configuration information required by the hot patch file; if the hot-patch file needs to depend on some application packages or tool packages to be loaded or run correctly, whether the application packages or tool packages on which the hot-patch file depends exist in the current operating system environment can be confirmed, and if the application packages or tool packages on which the hot-patch file depends exist, the current operating system environment can be generally determined to conform to operating system environment configuration information and the like required by the hot-patch file.

And step S106, operating the hot patch file in the current kernel environment and the current operating system environment based on the operating information.

After determining that the current kernel environment conforms to the kernel environment configuration information required by the hot patch file and the current operating system environment conforms to the operating system environment configuration information required by the hot patch file, it can be understood that the current kernel environment and the current operating system environment can ensure that the hot patch file can be correctly used. If the current kernel environment does not conform to the kernel environment configuration information required by the hot patch file or the current operating system environment does not conform to the operating system environment configuration information required by the hot patch file, the hot patch file will not generally be run in the current kernel environment and the current operating system environment.

The operation method of the hot patch comprises the following steps of firstly obtaining a hot patch file package; wherein, the hot patch file package includes: the hot patch file and a configuration file corresponding to the hot patch file; the configuration file includes: kernel environment configuration information, operating system environment configuration information and operation information of the hot patch file, which are required by the operation of the hot patch file; then determining that the current kernel environment conforms to kernel environment configuration information required by the hot patch file, and the current operating system environment conforms to operating system environment configuration information required by the hot patch file; and finally, running the hot patch file in the current kernel environment and the current operating system environment based on the running operation information. In the method, the hot patch file package comprises the hot patch file and the configuration file, and can automatically execute related operations based on the kernel environment configuration information and the operating system environment configuration information in the configuration file to ensure that the current kernel environment conforms to the kernel environment configuration information, and the current operating system environment conforms to the operating system environment configuration information, and then automatically execute the hot patch file based on the operation information in the configuration file, so that operation and maintenance personnel are not required to execute operation and maintenance operations on the hot patch file, the correctness of the related operations executed when the hot patch file is used can be ensured, the risk of operation and maintenance work is reduced, and major faults are prevented from being caused.

The embodiment of the invention provides another operation method of a hot patch, which is realized on the basis of the method of the embodiment, and the method mainly describes a specific process of determining that the current kernel environment conforms to the kernel environment configuration information required by a hot patch file, and the current operating system environment conforms to the operating system environment configuration information required by the hot patch file, wherein in the method, the kernel environment configuration information comprises the following steps: running version information of a target kernel corresponding to the hot patch file; the operating system environment configuration information includes: running version information of a target operating system corresponding to the hot patch file; because the hot patch file depends strongly on the kernel version and the operating system version, the hot patch file can only be loaded into a matched kernel and an operating system, otherwise, the problem of loading or running error can occur, and even major faults can be caused, therefore, the kernel environment configuration information usually comprises the version information of a target kernel corresponding to the hot patch file, and different kernels can be distinguished through the version information; the operating system environment configuration information usually includes version information of a target operating system corresponding to the hot patch file, and different operating systems can be distinguished through the version information; as shown in fig. 2, the method comprises the steps of:

step S202, obtaining a hot patch file package; wherein, the hot patch file package includes: the hot patch file and a configuration file corresponding to the hot patch file; the configuration file includes: the method comprises the following steps of running kernel environment configuration information, operating system environment configuration information and running operation information of the hot patch file, wherein the kernel environment configuration information, the operating system environment configuration information and the running operation information are required by the hot patch file.

Step S204, if the version information of the current kernel is the same as that of the target kernel and the version information of the current operating system is the same as that of the target operating system, determining that the current kernel environment conforms to kernel environment configuration information required by the hot patch file and the current operating system environment conforms to operating system environment configuration information required by the hot patch file.

If the version information of the current kernel is the same as that of the target kernel and the version information of the current operating system is the same as that of the target operating system, the current kernel can be understood as the kernel matched with the hot patch file, the current operating system is the operating system matched with the hot patch file, the hot patch file can be normally loaded into the current kernel, and at this time, it can be determined that the current kernel environment conforms to kernel environment configuration information required by the hot patch file, and the current operating system environment conforms to operating system environment configuration information required by the hot patch file. During actual implementation, a certain naming rule can be set for the naming mode of the hot patch file package, so that the kernel version matched with the hot patch file can be distinguished through the name of the hot patch file package; for example, referring to an example of a naming rule shown in table 1, the naming rule includes Package name, Kernel Version, Release, Arch (system architecture), and suffix (suffix), that is, when naming a hot patch Package, naming is required according to the naming rule, and since the name of the hot patch Package includes Kernel Version information, the name of the hot patch Package can be used to distinguish Kernel versions adapted to different hot patch files, such as: the kernel version matched with the hot patch file package with the name of kpatch-name-3.10.0-123.el7.x86_64-0.9.1-1.x86_64.rpm is 3.10.0-123.el7.x86_ 64; the kernel version adapted by the hot patch file package with the name of kpatch-name-4.12.0-456.el7.x86_64-0.9.1-1.x86_64.rpm is 4.12.0-456.el7.x86_ 64; the kernel version adapted by the hot patch package with the name of kpatch-name-5.8.0-789.el7.x86_64-0.9.1-1.x86_64.rpm is 5.8.0-789.el7.x86 _64.

In this way, the hot patch files for repairing the same kernel problem can be simultaneously installed to a specified position although being adapted to different kernels, and the matched hot patch files can be automatically loaded to the started kernels according to different started kernels; it should be noted that, although the same kernel problem is repaired, the hot patch file is usually recompiled for different kernel versions, and the specific content of the hot patch file may be different.

TABLE 1

And step S206, operating the hot patch file in the current kernel environment and the current operating system environment based on the operating information.

The operation method of the hot patch obtains a hot patch file package; wherein, the hot patch file package includes: the hot patch file and a configuration file corresponding to the hot patch file; the configuration file includes: the method comprises the following steps of running kernel environment configuration information, operating system environment configuration information and running operation information of the hot patch file, wherein the kernel environment configuration information, the operating system environment configuration information and the running operation information are required by the hot patch file. And if the version information of the current kernel is the same as that of the target kernel, determining that the current kernel environment conforms to kernel environment configuration information required by the hot patch file, and the current operating system environment conforms to operating system environment configuration information required by the hot patch file. And running the hot patch file in the current kernel environment and the current operating system environment based on the running operation information. In the method, the hot patch file package comprises the hot patch file and the corresponding configuration file thereof, and can automatically execute the relevant operation based on the kernel environment configuration information and the operating system environment configuration information in the configuration file to ensure that the current kernel environment conforms to the kernel environment configuration information, and the current operating system environment conforms to the operating system environment configuration information, and then automatically execute the hot patch file based on the operation information in the configuration file, because the operation and maintenance personnel are not required to execute the operation and maintenance operation on the hot patch file, the correctness of the relevant operation executed when the hot patch file is used can be ensured, in addition, because the kernel environment configuration information comprises the version information of the target kernel corresponding to the hot patch file, and the operating system environment configuration information comprises the version information of the target operating system corresponding to the hot patch file, the hot patch file can be further ensured to run in the matched kernel and the operating system, so that the risk of running and maintaining work can be reduced, and major faults are avoided.

The embodiment of the invention provides another operation method of a hot patch, which is realized on the basis of the method of the embodiment, and the method mainly describes a specific process of determining that the current kernel environment conforms to the kernel environment configuration information required by a hot patch file, and the current operating system environment conforms to the operating system environment configuration information required by the hot patch file, wherein in the method, the kernel environment configuration information comprises the following steps: a first condition that a software package on which the hot patch file depends needs to meet; the operating system environment configuration information includes: a second condition that needs to be satisfied by an application package on which the hot patch file depends; the software package may be understood as a program or a set of programs having specific functions which may be used to perform a specific task; the software package on which the hot patch file depends can be other hot patch file packages, or can also be other programs and the like which need to be depended on; the first condition that the software package needs to meet may be that the software package is a software package of a specified version, or the version of the software package cannot be lower than the specified version, or the software package is a software package of a specified issue number, and the like, and specifically, the first condition that the software package that the hot patch file depends on needs to meet may be set according to actual requirements; the application package may be understood as a tool package and the like that an operation command needs to be used, and the second condition that the application package needs to satisfy may be that the application package is an application package of a specified version, or that the version of the application package cannot be lower than the specified version, and the like, and specifically, the second condition that the application package that the hot patch file depends on needs to satisfy may be set according to an actual requirement, which is not limited herein; as shown in fig. 3, the method comprises the steps of:

step S302, obtaining a hot patch file package; wherein, the hot patch file package includes: the hot patch file and a configuration file corresponding to the hot patch file; the configuration file includes: the method comprises the following steps of running kernel environment configuration information, operating system environment configuration information and running operation information of the hot patch file, wherein the kernel environment configuration information, the operating system environment configuration information and the running operation information are required by the hot patch file.

Step S304, whether a first software package meeting a first condition exists in the current kernel environment or not and whether a first application package meeting a second condition exists in the current operating system environment or not are judged.

In practical implementation, if the kernel environment configuration information includes a first condition that a software package dependent on a hot patch file needs to satisfy and the operating system environment configuration information includes a second condition that an application package dependent on the hot patch file needs to satisfy, it can be understood that, in order to enable the hot patch file to normally operate in the current kernel environment, other software packages and other application packages need to be relied on, and therefore, after the hot patch file package is obtained, it can be determined whether a first software package satisfying the first condition exists in the current kernel environment and whether a first application package satisfying the second condition exists in the current operating system environment.

Step S306, if the first software package does not exist, the first software package is obtained, and the first software package is loaded to the current kernel environment.

If the first software package meeting the first condition does not exist in the current kernel environment, the first software package needs to be acquired, for example, the first software package meeting the first condition may be automatically downloaded, and the acquired first software package may be installed at a specified location. If there are a plurality of first software packages satisfying the first condition, for example, if only the name of the first software package is specified and no version number or issue number is specified, the first software package with the highest version number or issue number is generally selected by default; of course, a specific first software package may also be directly specified, in this case, the specified first software package may be directly obtained, and after the first software package is obtained, the first software package may be loaded to the current kernel environment, so that it may be ensured that the first software package exists in the current kernel environment.

Step S308, if the first application program package does not exist, the first application program package is obtained, and the first application program package is installed in the current operating system environment.

If the first application package meeting the second condition does not exist in the current operating system environment, the first application package needs to be acquired, for example, the first application package meeting the second condition can be automatically downloaded, and the acquired first application package can be installed at a specified position. If a plurality of first application packages satisfying the second condition exist, for example, if only the name of the first application package is specified and no version number is specified, the first application package with the highest version number is generally selected by default; of course, a specific first application package may also be directly specified, in which case the specified first application package may be directly obtained, and after the first application package is obtained, the first application package may be installed to the current operating system environment, so that it may be ensured that the first application package exists in the current operating system environment.

Step S310, determining that the current kernel environment conforms to the kernel environment configuration information required by the hot patch file, and the current operating system environment conforms to the operating system environment configuration information required by the hot patch file.

If the first software package exists in the current kernel environment and the first application program package exists in the current operating system environment, the first software package can be understood as meeting the dependence condition required by normal loading and running of the hot patch file, the hot patch file can be normally loaded into the current kernel, and at this time, the current kernel environment can be determined to accord with the kernel environment configuration information required by the hot patch file, and the current operating system environment accords with the operating system environment configuration information required by the hot patch file. For example, the dependency relationship may be configured by a Requires configuration item, and assuming that the hot patch file needs to depend on the kpatch-runtime-0.9.1-1.el7. normal.rpm or higher, the related configuration may refer to the following:

Requires:kpatch-runtime>＝0.9.1

when the hot patch file needs to be loaded to the current kernel, the missing depended software packages meeting the conditions can be automatically installed and loaded; because the kernel environment configuration information is provided with the version number meeting the conditions, the software package with the lower version can be automatically deleted, and the software package with the loading version number meeting the requirements is installed.

Step S312, the hot patch file is executed in the current kernel environment and the current operating system environment based on the operation information.

The operation method of the hot patch obtains a hot patch file package; wherein, the hot patch file package includes: the hot patch file and a configuration file corresponding to the hot patch file; and judging whether a first software package meeting a first condition exists in the current kernel environment or not and whether a first application program package meeting a second condition exists in the current operating system environment or not. And if the first software package does not exist, acquiring the first software package. Loading the first software package to the current kernel environment, if the first application package does not exist, acquiring the first application package, and installing the first application package to the current operating system environment; determining that the current kernel environment conforms to the kernel environment configuration information required by the hot patch file, and determining that the current operating system environment conforms to the operating system environment configuration information required by the hot patch file. And running the hot patch file in the current kernel environment and the current operating system environment based on the running operation information.

For example, the post-processing operation may be: before deleting the hot patch file package, the configuration in the original configuration file is wrong, the wrong configuration is modified when the hot patch file is loaded, when the hot patch file is unloaded, the hot patch file is unloaded from the kernel, and then the modified configuration is recovered to the original wrong configuration; sh script configuration can be referred to as follows:

step one, obtaining a hot patch file and a configuration file corresponding to the hot patch file.

And step two, if an encapsulating instruction aiming at the hot patch file is received, encapsulating the hot patch file and the configuration file to generate a hot patch file package.

The package instruction can be understood as an instruction sent when a user needs to package a hot patch file, a corresponding configuration file and the like; in actual implementation, after a user develops and manufactures a hot patch file, the user can configure a configuration file corresponding to the hot patch file, adjust the relevant configuration in the configuration file according to the content of hot patch file repair, and configure the relevant operation command of the kpatch at the corresponding configuration position of the configuration file; after the relevant configuration in the configuration file is adjusted, the hot patch file and the corresponding configuration file can be packaged, the configuration file usually includes specific operation steps, some operation steps relate to script files related to the operation steps, and the script files and the hot patch file can be packaged together.

In specific implementation, the hot patch file can be manufactured, deployed and managed by using a related software Package management standard, such as an RPM (Red-Hat Package Manager) standard, a DEB (software Package Manager) standard and the like; the RPM is an open software package management standard invented by RedHat, and the standard is widely used in rhol (Red Hat Enterprise Linux), a Community Enterprise Operating System (one of Linux distribution), Fedora (one of Linux distribution, a fast, stable, and powerful Operating System for daily applications constructed by global Community enthusiasts), including Linux distribution such as OpenLinux (one of Linux distribution), s.u.s.e. (one of Linux distribution), and Turbo Linux (one of Linux distribution). A user does not need to pay attention to software implementation details, only needs simple installation and load deletion, and is convenient and quick to deploy. The dependence and restriction relation between the complex implementation details in the software and the software version is processed by the producer of the hot patch file package.

For convenience of description, taking the RPM standard as an example, in a specific implementation, an rpmbuild command may be used to pack a specified directory and a specified file according to a specified spec profile to generate an RPM packet, before the packing, a relevant checking step may be written into the spec profile to prevent an error from occurring when the RPM packet is made, and what files need to be packed to generate the RPM packet are generally configured in the spec profile, whether the files need to be loaded into a kernel, and the like.

Each kernel hot patch is configured in a spec configuration file according to different functions, different repaired problems and different required dependence and limiting conditions, and the installation environment can be automatically detected during installation, so that the kernel hot patch can be correctly used.

The generation method of the hot patch file package is described by taking an RPM standard as an example, the related operation and the dependency relationship of the kernel hot patch are configured in the spec configuration file, and the details of the related installation and deletion operation are encapsulated, so that the usability of the hot patch file is improved. As an alternative, other packaging and packaging manners may also be selected to improve the usability of the hotpatch file, for example, the DEB standard may be adopted to package the hotpatch file and the like into a DEB package, or may also be packaged into other packaging packages, the related deployment manner may refer to the related description in the foregoing embodiment, and since the files and the like related to the operation process are packaged, the problem of misoperation of the maintenance personnel may be avoided.
