Linux system assigns root user's permission for modifying kernel parameter, even modification subsystem call table is sensitive in this way
The parameter of information.For the consistency of maintenance and operation system kernel, need to save the address of the interrupt vector of subsystem call table,
To restore later.(SuSE) Linux OS saves the address of interrupt vector by array, and by interrupt vector number and system
Call number is associated, and the address of corresponding interrupt vector number He Interrupt Service Routine can be then searched by this corresponding relationship,
And it is saved.
Likewise, the address of the interrupt vector of subsystem call table can be modified to a corresponding handling routine, this routine
Distinctive function may be implemented, and the function of original system interrupt call routine can be compatible with.
The module that exactly linux kernel allows user that oneself is added removes modification subsystem call table, therefore can be in kernel mould
Personalized content is added in block, Lai Shixian is for all abduction for falling into kernel I/O operation.By this abduction, can obtain
Take all I/O operations for falling into kernel whether under specified monitoring catalogue, all texts under specified monitoring catalogue available in this way
Part change conditions, the synchronous working for carrying out next step for these files carry out the preparation in details.
When breaking on the way in the middle or exit this module, need to exit this linux kernel module, in order to maintain linux kernel
Integrality, need to restore original Interrupt Service Routine, due to the corresponding address of previous backup, need first here
Will seek system call table according to system call number, the corresponding address for the Interrupt Service Routine that goes back, then to this address domain into
Row write-back is to realize recovery operation.
Based on principles above, below to realize this synchronization mechanism process be further elaborated on.The process can be with
It is divided into following four process:
(1) load and initialization of kernel module
This process is to carry out the premise of follow-up work, needs to call corresponding system command in a program to complete to add
It carries, correspondingly, needing to be completed at the same time the binding and communication of upper layer calling process and kernel, i.e., is established by bind and netlink
This association.
Meanwhile each system parameter need to be initialized when module loading, acquisition, interrupt vector number including interrupt vector table
It obtains, the determination of Interrupt Service Routine and the backup for servicing routine address.
(2) identification of catalogue file is synchronized in drive module
The file system such as ext3, nfs that Linux is supported have benefited from a kind of unified frame, and here it is virtual file systems
System conversion, abbreviation Virtual File System (Virtual FileSystem, VFS).Virtual File System is one realized in kernel
A software layer, it both provided the calling of file system interface for user space program, and guaranteed system kernel various logic text
Part system realizes the level of abstraction that can be coexisted.The Virtual File System layered structure schematic diagram is as shown in Figure 3.
The application, which can use linux kernel, this virtual file system is kidnapped in kernel with the characteristic of adding module
System table, saves the first address of the entrance function of these file system tables in the module, then goes the respective function for realizing oneself,
It oneself realizes in function, the notice operation to upper layer main program may be implemented, pass through what is set up in the initialization procedure of front
File change situation under particular category is reflected to upper layer trunk by the channel netlink, after on upper layer, backbone module is recognized,
These files can be carried out with synchronous and processing operation accordingly.
For example, user program calls write system to call, Linux is made to fall into kernel.In kernel, Linux passes through system
Call list finds the realization function (i.e. sys_write) of write system calling, and executes the function.In sys_write,
The VFS layers of interface function vfs_write () for being directed to file write operations can be called.It, will be according to file in vfs_write ()
The file system type (such as ext3, reiserfs, nfs) of affiliated disk partition, finds the corresponding file_ of this document system
Operations structural body, and the function that write member is directed toward in the structural body is called, realize actual write operation.
The present invention exactly applies this characteristic, kidnaps the first address of vfs_write () function, that then realizes oneself writes behaviour
Make routine, realization notifies upper layer main program, after the completion of notice, returns to the first ground of corresponding original vfs_write () function
Location continues to execute down other system I/O write operations.
(3) operation and active module
After completing the above setting, module can be run, needs to issue related command activation from upper layer main-line program.
After module operation, according to principles above, the driving function to existing setting may be implemented.In the process, as long as not exiting
Module, this function continuously effective.
(4) terminate and exit module
When system maintenance or replacement drive module version, needs to close driving function and exit module, at this point,
It needs to issue related command from upper layer trunk, terminates and exit module, it is emphasized that, before exiting module, in order to tie up
The integrality for protecting operating system nucleus, needs to restore the content of previous backup.
