With reference to figure 2, show the flow chart of steps of the manner of execution embodiment 1 of a kind of registry operations of the present invention, specifically can may further comprise the steps:
Step 201, obtain the registry operations request, comprise the caller input parameter in the described request;
Step 202, the said caller input parameter of foundation are provided with registration table kernel actuating logic, and said kernel actuating logic comprises: distort a detection and repair a logic and a registry functions calling logic;
In concrete the realization; When getting access to the registry operations request; Can carry out verification to the caller input parameter that comprises in the request,, then can the registry functions calling logic be set through structure _ PARSE_CONTEXT (context parsing) structure if verification is passed through; And, be arranged on registry functions and call a detection reparation logic of distorting of carrying out before.Promptly through initiatively removing " simulation " kernel execution level, oneself removes calling system bottom function after realizing structure _ PARSE_CONTEXT structure to present embodiment again.
In another kind of preferred embodiment of the present invention; Can also be through the method for " forgery " kernel; Hint obliquely at internal memory to the kernel file on the disk; After reorientation, the complete relevant execution level function (because be complete extraction, so its inside comprises " structure _ PARSE_CONTEXT structure ") that extracts.
Certainly, the above-mentioned method that registration table kernel actuating logic is set is only as example, and it all is feasible that those skilled in the art adopt any mode that registration table kernel actuating logic is set according to actual conditions, and the present invention does not limit this.
Step 203, carry out said distort to detect repair a logic, be specially, detect the kernel that presets and carry out stream and distort a little, and when said kernel is carried out stream and distorted a little original value and change, recover said kernel and carry out to flow and distort original value a little;
In concrete the realization, the said kernel that presets is carried out stream and distorted a little and can comprise: registry objects is resolved the routine hook; CmpCallBack callback mechanism when Cm* registration table realization routine call third party drives; The inline hook of Cm* registry functions; And, HvpGetCellPaged/HvpGetCellMapped object routine hook.The original value that each kernel execution stream is distorted a little can obtain when system initialization.
Certainly, above-mentioned kernel is carried out to flow to distort and a little only is used as example, and the said kernel that presets is carried out stream and distorted a little and can be provided with arbitrarily according to actual demand by those skilled in the art, and the present invention need not this to limit.
With reference to figure 3, in a kind of preferred embodiment of the present invention, kernel that said detection is preset is carried out stream and is distorted a little, and the said step of distorting an original value of recovery specifically can comprise following substep when kernel is carried out stream and distorted a little original value and change:
Whether the original value that substep S1, detection registry objects are resolved the routine hook changes, if, then carry out substep S2, otherwise, substep S3 carried out;
Substep S2, the said registry objects of recovery are resolved the original value of routine hook, rotor step S3;
Substep S3, call the Cm* registration table and realize routine, whether the original value that detects the inline hook of Cm* registry functions changes, if, then carry out substep S4, otherwise, substep S5 carried out;

In concrete the realization, as detect certain kernel and carry out stream and distort a little and change, then can write down its changing value at the kernel state memory headroom, so that after registry functions is called completion, carry out write-back.
Certainly; Above-mentioned detection and the restorative procedure of distorting a little only is used as example; It all is feasible that those skilled in the art are provided with said detection and reparation operating process of distorting a little arbitrarily according to actual demand, for example, can unify earlier to detect; Unified recovery of distorting to changing again, the present invention does not limit this.
Step 204, the said registry functions calling logic of employing call corresponding registry functions.
In concrete the realization, the embodiment of the invention can also comprise the steps:
Step 205, after having called the function of said registration table, said kernel is carried out the original value that stream distorts a little changes back changing value.
In reality; It a little is because of being rewritten by other fail-safe software and changing that some kernel execution stream is distorted; So after the realization function call of system bottom registration table is accomplished,, need carry out to flow to distort to said kernel and a little carry out write-back for guaranteeing the normal operation of other fail-safe software; Specifically can from the kernel state memory headroom, be extracted in the changing value of preserving in the recovery original value process, the kernel of correspondence carried out to flow to distort a little writing back this changing value.
After registry functions is called completion; Registry operations is carried out stream and is resolved routine with continuing to call registration table; Resolve routine call Cm* registration table by registration table again and realize routine, Cm* registration table realization routine is directly called the HvpGetCellPaged/HvpGetCellMapped object routine; Because the CmpCallBack callback mechanism is blocked, will no longer call the third party and drive so the Cm* registration table is realized routine, penetrated thereby make the third party drive (other fail-safe softwares, driving stage rogue program).
With reference to figure 4, show the flow chart of steps of the manner of execution embodiment 2 of a kind of registry operations of the present invention, specifically can comprise:
Step 401, loading registry operations interface program obtain the kernel execution stream that presets and distort original value a little;
Be well known that routine is the functional interface that externally provides of certain system or the set of service.Such as the API of operating system, service etc. is exactly routine.
As a kind of example of concrete application, said registry operations interface program can comprise: registry key is created routine BRegCreateKey, registration table and is strengthened key and create routine BRegCreateKeyEx, registry key and open routine BRegOpenKey, registration table and strengthen key and open routine BRegOpenKeyEx, registration table and strengthen Query Value routine BRegQueryValueEx, registration table settings routine BRegSetValueEx, registration table and enumerate key routine BRegEnumKey, registration table and strengthen and enumerate key routine BRegEnumKeyEx, registration table enumerated value routine BRegEnumValue, registration table delete key routine BRegDeleteKey, registration table and strengthen delete key routine BRegDeleteKeyEx, registration table deletion value routine BRegDeleteValue and/or registration table and close handle routine BRegCloseKey.The setting of said registry operations interface program, consistent like calling convention, call parameters with corresponding WINDOWS standard A PI.Above-mentioned each routine includes narrow character routine and wide character routine; For example for BRegCreateKey; Comprise narrow character routine BRegCreateKeyA and wide character routine BRegCreateKeyW; It is the UNICODE type that BRegCreateKeyA can change input parameter, the actual completion of BRegCreateKeyW Parameters Transformation, control code communication etc.
Step 402, caller are initiated the registry operations request, call corresponding registry operations interface program; Wherein, comprise the caller input parameter in the described request;
Step 403, if said registry operations interface program is narrow character routine, then convert the ANSI correlation parameter in the caller input parameter into the UNICODE type, and call corresponding registry operations interface wide character routine;
Be well known that the character among the ANSI adopts 8bit, and the character among the UNICODE adopts 16bit.(ANSI deposits English character with byte for character, deposits characters such as Chinese with double byte, and under the Unicode, English character with Chinese is all deposited with double byte).
Certainly, be the wide character routine as if what in reality, directly call, then need not to carry out this step.
Step 404, make up the kernel state structural parameters, generate corresponding registry operations control code according to said kernel state structural parameters, and be sent to the operating system nucleus attitude according to the type of system platform;
The type of said system platform comprises 32,64 and 32 compatibility modes.As the example of a kind of concrete application of the present invention, comprise with the corresponding control code of said registry operations interface program: registration table is created control code REGCTL_CREATE_KEY, registration table and is opened control code REGCTL_OPEN_KEY, registry query value control code REGCTL_QUERY_VALUE_KEY, registration table settings control code REGCTL_SET_VALUE_KEY, registration table and enumerate key control sign indicating number REGCTL_ENUMERATE_KEY, registration table enumerated value control code REGCTL_ENUMERATE_VALUE_KEY, registration table delete key control code REGCTL_DELETE_KEY and/or registration table deletion value control code REGCTL_DELETE_VALUE_KEY.Said control code has defined operating system user attitude and kernel state and has driven unified sign the when communicate by letter.
In reality, operating system user's attitude drives when communicating by letter with kernel state and imports, output buffer can adopt the METHOD_BUFFERED mode to transmit.The METHOD_BUFFERED mode is: first distributing buffer, again from these buffering copy data, buffer size is bigger that in space between input buffering and output buffering.Read to cushion by copy to new buffering.Before returning, just the copy rreturn value is to identical buffering.Rreturn value is placed to IO_STATUS_BLOCK, and IO manager copy data are to the output buffering.
Step 405, operating system nucleus attitude are obtained the registry operations request, verification caller input parameter, and the said user's attitude of reconstruct (Captured) address is to the kernel state memory headroom;
Step 406, if the input parameter verification is passed through, then according to said caller input parameter structure _ PARSE_CONTEXT structure, so that the registry functions calling logic to be set, and registration table kernel actuating logic is set;
Step 407, carry out said distort to detect repair a logic, be specially, detect the kernel that presets and carry out stream and distort a little, and when said kernel is carried out stream and distorted a little original value and change, recover said kernel and carry out to flow and distort original value a little;
Step 408, the said registry functions calling logic of employing call corresponding registry functions; If call success, then execution in step 409; If malloc failure malloc, then execution in step 410;
Step 409, return corresponding handle;
Step 410, generation error sign indicating number also return user's attitude;
In concrete the realization, if malloc failure malloc, user's attitude interface can be provided with the corresponding error sign indicating number, and like this, the caller thread can obtain detailed error message through the GetLastError routine.
Step 411, after having called the function of said registration table, said kernel is carried out the original value that stream distorts a little changes back changing value.
For making those skilled in the art understand the present invention better, below through being that example specifies the present invention with the registration table constructive process.
(1) the caller process is initiated the BRegCreateKeyA registration table and is created request;
(2) BRegCreateKeyA routine conversion ANSI correlation parameter is the UNICODE type and calls the BRegCreateKeyW routine;
(3) the BRegCreateKeyW routine judges that system platform (32,64 or 32 compatibility modes) makes up structural parameters, sends also synchronous wait of control code REGCTL_CREATE_KEY and returns;
(4) BRegCreateKeyW routine kernel portion receives the request of user's attitude, the verification input parameter, and the Captured address is to the kernel internal memory;
(5) BRegCreateKeyW routine structure _ PARSE_CONTEXT structure, calling system bottom registration table is realized function; Distort a detection below before calling, carrying out and repair operation:
A1, detection, the potential registry objects of recovery are resolved routine hook problem;
A2, detection, the potential CmpCallback kernel readjustment problem of recovery;
A3, detection, the potential inline hook problem of Cm* level registry functions of recovery;
A4, detection, the potential HvpGetCellPaged/HvpGetCellMapped object routine hook problem of recovery.
(6) then return corresponding handle as calling success; Like the routine call mistake, drive and return user's attitude corresponding error sign indicating number.
