    Hooking File System on Linux OS



    Hello All,

    I want to implement a layer before linux file system and copy (passively i.e. without hindering the normal file i/o operation) all the data which is getting written (fwrite or write) on the hard disk.

    This operation I want to do for only few opened files.

    Please suggest.

    hm.. you can overwrite standard syscalls with using syscalls table, but you must patch 2.6 kernel for opening this feature
