With the active defense method, a project source code is analyzed in advance to find factors which may possibly affect binary equivalence of the code, such as the timestamp, the random number, the file order and a character set, and the factors are modified to be constants on the premise that program logic is not affected, so as to realize binary consistency of a plurality of construction results, thereby proving binary equivalence of the code to be audited.

Nowadays, the auditing requirements for the codes become stricter and stricter, and more and more extensive in consideration of security, and the auditing of the binary equivalence of the codes also becomes an important index.
There are two general methods for auditing of the binary equivalence of the codes in the industry: the passive analysis method and the active defense method.
With the passive analysis method, a plurality of code construction results are compared, and it is demonstrated by analysis that a difference between the results is caused by factors which do not affect program logic, such as the timestamp, the random number and the file order, so that binary equivalence of a code to be audited is indirectly proved. However, this method, i.e., performing passive analysis when faced with a difference, has the following disadvantages: (1) poor timeliness: if analysis is performed merely after the difference is found, a time requirement of a user can hardly be met, and a difference analysis report cannot be provided for the user in time; (2) poor reusability: due to low reusability of an analysis result, a large amount of time-consuming and labor-consuming analysis work may have to be repeated after a project is replaced; and (3) low analysis efficiency: since a difference is transmitted in a construction process, a minor difference at the beginning of the construction process can cause a large difference between final results, and for finding a root cause of the difference between the construction results, reverse tracing and layer-by-layer analysis are needed when passive analysis is carried out, resulting in an analysis process which is time-consuming and labor-consuming and is low in efficiency.
With the active defense method, a project source code is analyzed in advance to find factors which may possibly affect binary equivalence of the code, such as the timestamp, the random number, the file order and the character set, and the factors are modified to be constants on the premise that program logic is not affected, so as to realize binary consistency of a plurality of construction results, thereby proving binary equivalence of the code to be audited. However, this method has the following disadvantages: (1) poor reusability: since the work of analyzing and modifying the project source code cannot be reused, complex work of project analysis and modification has to be repeated after the project is replaced; and (2) low analysis efficiency: the project needs to be analyzed manually, resulting in a heavy workload, and omissions may occur.
As shown in
In operation S110, at least two test construction commands are generated according to different environment variables in a code construction command.
The environment variables include: at least one of a user name, system time, a timestamp, a random number, a file order or a character set.
The environment variables are variables included in the code construction command. For example, if the code construction command is a command to generate an archive file, the environment variable is the timestamp.
The different environment variables may be environment variables of different types, or different values corresponding to a same type of environment variable. For example, the different environment variables may be a timestamp A and a timestamp B, or may be the timestamp A and a user name C, which is not limited herein.
In an implementation, a project construction process, which refers to a process of binary conversion of a code, is tracked, a code construction command executed in the project construction process is monitored, execution of the code construction command is suspended, and at least two test construction commands are generated according to different environment variables. For example, the project construction process, which refers to the process of binary conversion of the code, is tracked, the code construction command executed in the project construction process is monitored, the execution of the code construction command is suspended, if the environment variables are system time A and system time B, one test construction command is generated according to the system time A, and one test construction command is generated according to the system time B; or, if the environment variables are the system time A and the user name C, one test construction command is generated according to the system time A, and one test construction command is generated according to the user name C; or, if the environment variables are a timestamp Q, a random number M and the user name C, one test construction command is generated according to the timestamp Q, one test construction command is generated according to the random number M, and one test construction command is generated according to the user name C; or, if the environment variables are the system time A, the system time B, and system time P, one test construction command is generated according to the system time A, one test construction command is generated according to the system time B, and one test construction command is generated according to the system time P.

For example, if the environment variables are the system time A and the system time B, one test construction command is generated according to the system time A, one test construction command is generated according to the system time B, the test construction command generated according to the system time A is executed on the code, and the test construction command generated according to the system time B is executed on the code; if the environment variables are the system time A, the system time B and the system time P, one test construction command is generated according to the system time A, one test construction command is generated according to the system time B, one test construction command is generated according to the system time P, the test construction command generated according to the system time A is executed on the code, the test construction command generated according to the system time B is executed on the code, and the test construction command generated according to the system time P is executed on the code; or, if the environment variables are the timestamp Q, the random number M, and the user name C, one test construction command is generated according to the timestamp Q, one test construction command is generated according to the random number M, one test construction command is generated according to the user name C, the test construction command generated according to the timestamp Q is executed on the code, the test construction command generated according to the random number M is executed on the code, and the test construction command generated according to the user name C is executed on the code.
In an implementation, if the execution results are inconsistent, adjusting the code construction command according to the environment variables in the code construction command may include the following operations. For example, if the environment variables are the system time A and the system time B, one test construction command is generated according to the system time A, one test construction command is generated according to the system time B, the test construction command generated according to the system time A is executed on the code, the test construction command generated according to the system time B is executed on the code, an execution result obtained by executing the test construction command generated according to the system time A on the code is the execution result X, an execution result obtained by executing the test construction command generated according to the system time B on the code is the execution result Y, and the execution results are inconsistent because the execution result X is different from the execution result Y, then the code construction command is adjusted according to the system time; if the environment variables are the system time A, the system time B and the system time P, one test construction command is generated according to the system time A, one test construction command is generated according to the system time B, one test construction command is generated according to the system time P, the test construction command generated according to the system time A is executed on the code, the test construction command generated according to the system time B is executed on the code, the test construction command generated according to the system time P is executed on the code, an execution result obtained by executing the test construction command generated according to the system time A on the code is the execution result X, an execution result obtained by executing the test construction command generated according to the system time B on the code is the execution result Y, an execution result obtained by executing the test construction command generated according to the system time P on the code is the execution result Z, and the execution results are inconsistent because the execution result X, the execution result Y and the execution result Z are different from one another, then the code construction command is adjusted according to the system time; or, if the environment variables are the timestamp Q, the random number M, and the user name C, one test construction command is generated according to the timestamp Q, one test construction command is generated according to the random number M, one test construction command is generated according to the user name C, the test construction command generated according to the timestamp Q is executed on the code, the test construction command generated according to the random number M is executed on the code, the test construction command generated according to the user name C is executed on the code, an execution result obtained by executing the test construction command generated according to the timestamp Q on the code is the execution result X, an execution result obtained by executing the test construction command generated according to the random number M on the code is the execution result X, an execution result obtained by executing the test construction command generated according to the user name C on the code is the execution result Y, and the execution results are inconsistent because the execution results X and the execution result Y are different from one another, then the code construction command is adjusted according to the timestamp, the random number and the user name.
In operation S130, the adjusted code construction command is executed on the code.
In an implementation, executing the adjusted code construction command on the code may include the following operations. For example, if the environment variable is the timestamp, system time of the code construction command is adjusted to a fixed value, and the code construction command with the system time adjusted to the fixed value is executed on the code; and if the environment variable is a file list order, the code construction command is adjusted to be a command to sort, after the execution results are obtained, the execution results with a sorting tool, and the adjusted code construction command is executed on the code.
By generating the at least two test construction commands according to the different environment variables in the code construction command, respectively executing the at least two test construction commands on the code, adjusting, if the execution results are inconsistent, the code construction command according to the environment variables in the code construction command, and executing the adjusted code construction command on the code, the code construction method provided by the present disclosure can allow a plurality of code construction results to be consistent, and automatically realize reproducible code construction.
On the basis of the above implementations, modified implementations of the above implementations are proposed. It should be noted that merely the differences from the above implementations are described in the following modified implementations for the purpose of conciseness.
In an implementation, adjusting the code construction command according to the environment variables in the code construction command includes: searching a database according to the code construction command to obtain a first adjustment rule corresponding to the code construction command; and adjusting each environment variable in the code construction command according to the first adjustment rule.
A database about corresponding relationships between code construction commands and adjustment rules is established in advance. For example, the database stores a code construction command W and adjustment rules of all environment variables in the code construction command W; a code construction command G and adjustment rules of all environment variables in the code construction command G; and a code construction command K and adjustment rules of all environment variables in the code construction command K.
The first adjustment rule may include adjustment rules of all the environment variables in the code construction command. For example, if the code construction command includes an environment variable D and an environment variable E, the first adjustment rule includes an adjustment rule of the environment variable D and an adjustment rule of the environment variable E.
In an implementation, searching the database according to the code construction command to obtain the first adjustment rule corresponding to the code construction command and adjusting each environment variable in the code construction command according to the first adjustment rule may include the following operations. For example, the database is searched according to the code construction command W to obtain the adjustment rules of all the environment variables in the code construction command W; if all the environment variables in the code construction command W are the environment variable D and the environment variable E, the adjustment rule of the environment variable D and the adjustment rule of the environment variable E are obtained, the environment variable D in the code construction command W is adjusted according to the adjustment rule of the environment variable D, and the environment variable E in the code construction command W is adjusted according to the adjustment rule of the environment variable E.
In an implementation, adjusting each environment variable in the code construction command according to the first adjustment rule includes: if the code construction command includes the timestamp, setting system time corresponding to the code construction command to be fixed time; if the code construction command includes the random number, building a target file system, and replacing a file system corresponding to the code construction command with the target file system so as to allow files to be archived to have fixed node information; and if the code construction command includes the file list order, sorting at least one execution result corresponding to the code construction command with a sorting tool.
The code construction command may include at least one of the timestamp (environment variable), the random number (environment variable) or the file list order (environment variable).
In an implementation, setting the system time corresponding to the code construction command to be the fixed time if the code construction command includes the timestamp, building the target file system and replacing the file system corresponding to the code construction command with the target file system so as to allow the files to be archived to have the fixed node information if the code construction command includes the random number, and sorting the at least one execution result corresponding to the code construction command with the sorting tool if the code construction command includes the file list order may include the following operations. For example, if the code construction command includes the timestamp alone, merely the system time corresponding to the code construction command needs to be set to be the fixed time; if the code construction command includes the timestamp and the random number, the system time corresponding to the code construction command needs to be set to be the fixed time, the target file system needs to be built, and the file system corresponding to the code construction command needs to be replaced with the target file system so as to allow the files to be archived to have the fixed node information; and if the code construction command includes the timestamp, the random number and the file list order, the system time corresponding to the code construction command needs to be set to be the fixed time, the target file system needs to be built, the file system corresponding to the code construction command needs to be replaced with the target file system so as to allow the files to be archived to have the fixed node information, and the at least one execution result corresponding to the code construction command needs to be sorted with the sorting tool.
In an implementation, adjusting the code construction command according to the environment variables in the code construction command includes: searching a database according to environment variables corresponding to the at least two test construction commands to obtain a second adjustment rule corresponding to the environment variables; and adjusting the environment variables according to the second adjustment
A database about corresponding relationships between the environment variables and adjustment rules is established in advance. For example, the database includes the environment variable D and the adjustment rule of the environment variable D, an environment variable R and an adjustment rule of the environment variable R, and an environment variable H and an adjustment rule of the environment variable H.
The second adjustment rule may include adjustment rules of the environment variables corresponding to the test construction commands.
In an implementation, the environment variable that causes the inconsistency of the execution results is determined in advance according to the test construction commands, and the number of the environment variables that cause the inconsistency of the execution results may be one or more than one. For example, when it is determined according to the test construction commands that the environment variable that causes the inconsistency of the execution results is the environment variable D, the database is searched to obtain the adjustment rule of the environment variable D, and the environment variable D is adjusted according to the adjustment rule of the environment variable D.
It should be noted that the code construction command may include a plurality of environment variables, and the number of the environment variables that cause the inconsistency of the execution results may be one or more than one. For example, the code construction command includes an environment variable Q, the environment variable D, and the environment variable R, and the environment variable that causes the inconsistency of the execution results is the environment variable Q; or, the code construction command includes the environment variable Q and the environment variable D, and the environment variables that cause the inconsistency of the execution results are the environment variable Q and the environment variable D; and if the environment variables that cause the inconsistency of the execution results are the environment variable Q and the environment variable D, the database is searched according to the environment variable Q to obtain an adjustment rule of the environment variable Q, and is searched according to the environment variable D to obtain the adjustment rule of the environment variable D.
In an example, the code construction command includes the environment variable Q, the environment variable D and the environment variable R, so that a test construction command N1 is generated according to the environment variable Q1 in the code construction command, a test construction command N2 is generated according to the environment variable Q2 in the code construction command, a test construction command V1 is generated according to the environment variable D1 in the code construction command, a test construction command V2 is generated according to the environment variable D2 in the code construction command, a test construction command U1 is generated according to the environment variable R1 in the code construction command, and a test construction command U2 is generated according to the environment variable R2 in the code construction command; and if an execution result of the test construction command N1 is consistent with that of the test construction command N2, an execution result of the test construction command V1 is inconsistent with that of the test construction command V2, an execution result of the test construction command U1 is consistent with that of the test construction command U2, then the database is searched according to the environment variable D to obtain the adjustment rule of the environment variable D, and the environment variable D is adjusted according to the adjustment rule of the environment variable D.
In an implementation, adjusting the environment variables according to the second adjustment rule includes: if the environment variable in the code construction command is the timestamp, setting system time corresponding to the code construction command to be fixed time.
The fixed time may be set by a system or set manually, which is not limited herein.
In an implementation, if the environment variable in the code construction command is the timestamp, setting the system time corresponding to the code construction command to be the fixed time may include the following operations. For example, it is detected that a reason for irreproducible construction in a project is the timestamp: for example, in a case where a tar tool is used to generate an archive file (since a timestamp is generated in a file header according to current system time when an archive file is generated according to a tar command, binary inconsistency of archive files generated by executing the same tar command twice occurs due to different timestamps in the file headers); and the database is searched to find a corresponding adjustment rule, for example, for the tar command to generate an archive file, a new tar command is built by a monitoring module, and system time of execution of the tar command is set to be the same fixed time, thus ensuring binary consistency of archive files generated by executing the same tar command for a plurality times.
In an implementation, adjusting the environment variables according to the second adjustment rule includes: if the environment variable in the code construction command is the random number, building a target file system; and replacing a file system corresponding to the code construction command with the target file system so as to allow files to be archived to have fixed node information.
In an implementation, if the environment variable in the code construction command is the random number, building the target file system, and replacing the file system corresponding to the code construction command with the target file system so as to allow the files to be archived to have the fixed node information may include the following operations. For example, it is detected that a reason for irreproducible construction in a project is the random number: for example, in a case where a cpio file is generated and inode of a file packed into the cpio file is a random number; and the database is searched to find a corresponding adjustment rule, for example, a random problem of inode of a file packed into a cpio file is generated (an independent file system such as ext4 is built, files to be packed are sequentially copied into the independent file system to be given a fixed inode value, and then a cpio file is generated in the independent file system, so that binary consistency of cpio files generated in a plurality of construction processes can be realized).
In an implementation, adjusting the environment variables according to the second adjustment rule includes: if the environment variable in the code construction command is the file list order, sorting at least one execution result corresponding to the code construction command with a sorting tool.
In an implementation, if the environment variable in the code construction command is the file list order, sorting the at least one execution result corresponding to the code construction command with the sorting tool may include the following operations. For example, it is detected that irreproducible construction in a project is caused by the file list order: for example, in a case where a find command is executed and a sequence of a plurality of results found is not fixed; and the database is searched to find a corresponding adjustment rule, for example, for the find command, the plurality of results found are sorted with a sorting tool such as sort, so that results found by executing the find command for a plurality of times are consistent.
In an implementation, generating the at least two test construction commands according to the different environment variables in the code construction command includes: tracking a code construction process, and monitoring the code construction command executed in the code construction process; when the code construction command is acquired, suspending execution of the code construction command; and generating the at least two test construction commands according to the different environment variables in the code construction command.
In an example, a whole project construction process is tracked; code construction commands executed in the project construction process are monitored; execution of a current code construction command is suspended; two test construction commands are built, and are configured with different environment variables (factors such as the user name and the system time which may cause irreproducible construction); the two newly built test construction commands are sequentially executed; and output results of the two test construction commands are compared, and it is determined that the current code construction command is a code construction command which cannot be reproducibly constructed if the output results are inconsistent.
In another example, a project construction process is monitored (by using ptrace, for example); an environment variable causing irreproducible construction in the project is detected; an adjustment rule corresponding to the environment variable is found in a database; the environment variable is adjusted according to the adjustment rule to obtain a new code construction command; an original code construction command is replaced with the new code construction command; and the new code construction command is executed.
According to the present disclosure, adjustment rules of environment variables causing irreproducible construction are provided in advance, and stored in a database; and after a new adjustment rule is obtained, the new adjustment rule is added to the database to update the database in real time.
According to the present disclosure, an existing analysis result of irreproducible construction can be reused to automatically position and repair the environment variable causing the irreproducible construction in the project construction process, without modifying a project source code, so that binary consistency of a plurality of construction processes can be ensured, thereby conveniently achieving an audit of code binary equivalence.
In another example, a project construction process is monitored; it is detected that a reason for irreproducible construction in the project is the timestamp: for example, in a case where a tar tool is used to generate an archive file (since a timestamp is generated in a file header according to current system time when an archive file is generated according to a tar command, binary inconsistency of archive files generated by executing the same tar command twice occurs due to different timestamps in the file headers); the database is searched according to the timestamp to find an adjustment rule corresponding to the timestamp, for example, for the tar command to generate an archive file, a new tar command is built by a monitoring module, and system time of execution of the tar command is set to be the same fixed time, thus ensuring binary consistency of archive files generated by executing the same tar command for a plurality times; and the timestamp is adjusted according to the adjustment rule to obtain the adjusted code construction command, and the adjusted code construction command is executed on the code.
In another example, a project construction process is monitored; it is detected that a reason for irreproducible construction in the project is the random number: for example, in a case where a cpio file is generated and inode of a file packed into the cpio file is a random number; and the database is searched according to the random number to find an adjustment rule corresponding to the random number, for example, a random problem of inode of a file packed into a cpio file is generated (an independent file system such as ext4 is built, files to be packed are sequentially copied into the independent file system to be given a fixed inode value, and then a cpio file is generated in the independent file system, so that binary consistency of cpio files generated in a plurality of construction processes can be realized); and the code construction command is adjusted according to the adjustment rule, and the adjusted code construction command is executed on the code.
In another example, a project construction process is monitored; it is detected that a reason for irreproducible construction in the project is the file list order: for example, in a case where a find command is executed and a sequence of a plurality of results found is not fixed; and the database is searched according to the file list order to find an adjustment rule corresponding to the file list order, (for example, for the find command, the plurality of results found are sorted with a sorting tool such as sort, so that results found by executing the find command for a plurality of times are consistent), and the code construction command is adjusted according to the adjustment rule, and the adjusted code construction command is executed on the code.
In another example, project construction is initiated; the project construction is monitored; code construction commands executed in the project construction process are monitored; execution of a current code construction command is suspended; two test construction commands are built (different environment variables are configured to allow the two commands to use different factors such as the system time and the user name which may cause irreproducible construction); the first test construction command is executed; the second test construction command is executed; execution results of the two test construction commands are compared, and if binary inconsistency of the execution results occurs, a reason for irreproducible construction is positioned; the execution of the suspend command is resumed; and the construction process is detected, the operation of monitoring the code construction commands executed in the project construction process is performed if the construction is not completed, and the flow is ended if the construction is completed.
In another example, a database is established, with the data base storing environment variables which cause binary inconsistency of a plurality of construction processes, and adjustment rules of the environment variables; project construction is initiated; the project construction is monitored; an environment variable which causes irreproducible construction is detected; an adjustment rule of the detected environment variable which causes the irreproducible construction is acquired from the database; and the environment variable is adjusted according to the adjustment rule to obtain an adjusted code construction command. The adjusted code construction command is executed, the construction process is detected, the operation of monitoring code construction commands executed in the project construction process is performed if the construction is not completed, and the flow is ended if the construction is completed.
