SgAsmGenericFile::SgAsmGenericFile ( )

Default constructor.

Member Function Documentation

int const& SgAsmGenericFile::get_fd ( ) const

Property: Read-only file descriptor.

Negative represents lack of valid file descriptor.

void SgAsmGenericFile::set_fd ( int const &  )

Property: Read-only file descriptor.

Negative represents lack of valid file descriptor.

SgAsmGenericHeaderList* const& SgAsmGenericFile::get_headers ( ) const

Property: List of all headers in file.

This is stored as a pointer to another node that contains the list due to limitations of ROSETTA.

void SgAsmGenericFile::set_headers ( SgAsmGenericHeaderList *const &  )

Property: List of all headers in file.

This is stored as a pointer to another node that contains the list due to limitations of ROSETTA.

SgAsmGenericSectionList* const& SgAsmGenericFile::get_holes ( ) const

Property: Addresses unreferenced during parsing.

This is a pointer to a node that contains a list of pointers to the holes. It is done this way rather than storing the list directly, because of limitations of ROSETTA.

void SgAsmGenericFile::set_holes ( SgAsmGenericSectionList *const &  )

Property: Addresses unreferenced during parsing.

This is a pointer to a node that contains a list of pointers to the holes. It is done this way rather than storing the list directly, because of limitations of ROSETTA.

SgAsmGenericFile* SgAsmGenericFile::parse ( std::string  file_name)

Loads file contents into memory.

void SgAsmGenericFile::reallocate ( )

Call this before unparsing to make sure everything is consistent.

void SgAsmGenericFile::unparse ( std::ostream &  ) const

Mirror image of parsing an executable file.

The result (unless the AST has been modified) should be identical to the original file. If the file's neuter property is true, then rather than creating a binary file, the output will contain a note indicating that the neuter property is set. This is intended to prevent ASTs that represent malicious binaries from accidently being used to create the binary.

void SgAsmGenericFile::extend_to_eof ( std::ostream &  ) const

Extend the output file by writing the last byte if it hasn't been written yet.

void SgAsmGenericFile::dump ( FILE *  ) const

Print basic info about the sections of a file.

void SgAsmGenericFile::dump_all ( bool  in_cwd = true,
const char *  ext = NULL 
)

Print text file containing all known information about a binary file.

If in_cwd is set, then the file is created in the current working directory rather than the directory containing the binary file (the default is to create the file in the current working directory). If ext is non-null then these characters are added to the end of the binary file name. The default null pointer causes the string ".dump" to be appended to the file name.

void SgAsmGenericFile::dump_all ( const std::string &  dumpname)

Print text file containing all known information about a binary file.

const AddressIntervalSet& SgAsmGenericFile::get_unreferenced_extents ( ) const

Returns the parts of the file that have never been referenced.

void SgAsmGenericFile::mark_referenced_extent ( rose_addr_t  start_rva,
rose_addr_t  size 
)

Marks part of a file as having been referenced if tracking references.

void SgAsmGenericFile::set_data_converter ( DataConverter dc)
inline

Property: Data converter.

Function to encode/decode data as it's transferred to/from disk. The default is to do no transformation.

Definition at line 13799 of file binaryInstruction.C.

DataConverter* SgAsmGenericFile::get_data_converter ( ) const
inline

Property: Data converter.

Function to encode/decode data as it's transferred to/from disk. The default is to do no transformation.

Definition at line 13800 of file binaryInstruction.C.

rose_addr_t SgAsmGenericFile::get_current_size ( ) const

Returns current size of file based on section with highest ending address.

rose_addr_t SgAsmGenericFile::get_orig_size ( ) const

Returns original size of file, based on file system.

size_t SgAsmGenericFile::read_content ( rose_addr_t  offset,
void *  dst_buf,
rose_addr_t  size,
bool  strict = true 
)

Reads data from a file.

Reads up to size bytes of data from the file beginning at the specified byte offset (measured from the beginning of the file), placing the result in dst_buf, and returning the number of bytes read. If the number of bytes read is less than size then one of two things happen: if strict is true then an SgAsmExecutableFileFormat::ShortRead exception is thrown; otherwise dst_buf is zero padded so that exactly size bytes are always initialized.

size_t SgAsmGenericFile::read_content ( const Rose::BinaryAnalysis::MemoryMap::Ptr ,
rose_addr_t  va,
void *  dst_buf,
rose_addr_t  size,
bool  strict = true 
)

Reads data from a file.

Reads up to size bytes of data starting at the specified (absolute) virtual address. The map specifies how virtual addresses are mapped to file offsets. As bytes are read, if we encounter a virtual address that is not mapped we stop reading and do one of two things: if strict is set then a MemoryMap::NotMapped exception is thrown; otherwise the rest of the dst_buf is zero filled and the number of bytes read (not filled) is returned.

std::string SgAsmGenericFile::read_content_str ( const Rose::BinaryAnalysis::MemoryMap::Ptr ,
rose_addr_t  va,
bool  strict = true 
)

Reads a string from a file.

Returns the string stored at the specified (absolute) virtual address. The returned string contains the bytes beginning at the starting virtual address and continuing until we reach a NUL byte or an address which is not mapped. If we reach an address which is not mapped then one of two things happen: if strict is set then a MemoryMap::NotMapped exception is thrown; otherwise the string is simply terminated. The returned string does not include the NUL byte.

std::string SgAsmGenericFile::read_content_str ( rose_addr_t  abs_offset,
bool  strict = true 
)

Reads a string from a file.

Returns the NUL-terminated string stored at the specified relative virtual address. The returned string contains the bytes beginning at the specified starting file offset and continuing until we reach a NUL byte or an invalid file offset. If we reach an invalid file offset one of two things happen: if strict is set (the default) then an SgAsmExecutableFileFormat::ShortRead exception is thrown; otherwise the string is simply terminated. The returned string does not include the NUL byte.

const SgFileContentList& SgAsmGenericFile::content ( )
inline

Property: Entire file contents.

Definition at line 13847 of file binaryInstruction.C.

SgFileContentList SgAsmGenericFile::content ( rose_addr_t  offset,
rose_addr_t  size 
)

Returns a vector that points to part of the file.

Returns a vector that points to part of the file content without actually ever reading or otherwise referencing the file content until the vector elements are referenced. If the desired extent falls entirely or partially outside the range of data known to the file then throw an SgAsmExecutableFileFormat::ShortRead exception. This function never updates reference tracking lists for the file.

SgAsmGenericSectionPtrList SgAsmGenericFile::get_mapped_sections ( ) const

Returns list of all sections in the file that are memory mapped, including headers and holes.

SgAsmGenericSectionPtrList SgAsmGenericFile::get_sections ( bool  include_holes = true) const

Returns list of all sections in the file (including headers, holes, etc).

SgAsmGenericSectionPtrList SgAsmGenericFile::get_sections_by_id ( int  id) const

Returns sections having specified ID across all headers, including headers and holes.

SgAsmGenericSectionPtrList SgAsmGenericFile::get_sections_by_name ( std::string  ,
char  sep = '\0' 
) const

Returns all sections having specified name across all headers, including headers and holes.

SgAsmGenericSectionPtrList SgAsmGenericFile::get_sections_by_offset ( rose_addr_t  offset,
rose_addr_t  size 
) const

Find sections by their offset.

Returns all sections that contain all of the specified portion of the file across all headers, including headers and holes.

SgAsmGenericSectionPtrList SgAsmGenericFile::get_sections_by_rva ( rose_addr_t  rva) const

Find sections by address.

Returns all sections that are mapped to include the specified relative virtual address across all headers, including headers and holes. This uses the preferred mapping of the section rather than the actual mapping.

SgAsmGenericSectionPtrList SgAsmGenericFile::get_sections_by_va ( rose_addr_t  va) const

Find sections by address.

Returns all sections that are mapped to include the specified virtual address across all headers, including headers and holes. This uses the preferred mapping rather than the actual mapping.

SgAsmGenericSection* SgAsmGenericFile::get_section_by_id ( int  id,
size_t *  nfound = 0 
) const

Find section with specified ID.

Returns the pointer to section with the specified ID across all headers only if there's exactly one match. Headers and holes are included in the results.

SgAsmGenericSection* SgAsmGenericFile::get_section_by_name ( const std::string &  ,
char  sep = 0,
size_t *  nfound = 0 
) const

Find section by name.

Returns pointer to the section with the specified name, or NULL if there isn't exactly one match. Any characters in the name after the first occurrence of SEP are ignored (default is NUL). For instance, if sep=='$' then the following names are all equivalent: .idata, .idata$, and .idata$1

SgAsmGenericSection* SgAsmGenericFile::get_section_by_offset ( rose_addr_t  offset,
rose_addr_t  size,
size_t *  nfound = 0 
) const

Find section by file offset.

Returns single section that contains all of the specified portion of the file across all headers, including headers and holes.

SgAsmGenericSection* SgAsmGenericFile::get_section_by_rva ( rose_addr_t  rva,
size_t *  nfound = 0 
) const

Find section by address.

Returns single section that is mapped to include the specified relative virtual file address across all headers, including headers and holes.

SgAsmGenericSection* SgAsmGenericFile::get_section_by_va ( rose_addr_t  va,
size_t *  nfound = 0 
) const

Find section by address.

Returns single section that is mapped to include the specified virtual address across all headers. See also get_best_section_by_va.

SgAsmGenericSection* SgAsmGenericFile::get_best_section_by_va ( rose_addr_t  va,
size_t *  nfound = 0 
) const

Find section by address.

Similar to get_section_by_va except when more than one section contains the specified virtual address this choose the "best" one. All candidates must map the virtual address to the same file address or else we fail (return null and number of candidates). See best_section_by_va for definition of "best".

static SgAsmGenericSection* SgAsmGenericFile::best_section_by_va ( const SgAsmGenericSectionPtrList &  sections,
rose_addr_t  va 
)
static

Definition for "best".

This is the definition of "best" as used by get_best_section_by_va and SgAsmGenericHeader::get_best_section_by_va. The specified list of sections is scanned and the best one containing the specified virtual address is returned. The operation is equivalent to the successive elimination of bad sections: first eliminate all sections that do not contain the virtual address. If more than one remains, eliminate all but the smallest. If two or more are tied in size and at least one has a name, eliminate those that don't have names. If more than one section remains, return the section that is earliest in the specified list of sections. Return the null pointer if no section contains the specified virtual address, or if any two sections that contain the virtual address map it to different parts of the underlying binary file.

void SgAsmGenericFile::shift_extend ( SgAsmGenericSection ,
rose_addr_t  sa,
rose_addr_t  sn,
AddressSpace  ,
Elasticity   
)

Moves and enlarges a section.

Shifts (to a higher offset) and/or enlarges the specified section, S, taking all other sections into account. The positions of sections are based on their preferred virtual mappings rather than the actual mapping.

The neighborhood(S) is S itself and the set of all sections that overlap or are adjacent to the neighborhood of S, recursively.

The address space can be partitioned into three categories:

  • Section: part of an address space that is referenced by an SgAsmGenericSection other than a "hole" section.
  • Hole: part of an address space that is referenced only by a "hole" section.
  • Unref: part of an address space that is not used by any section, including any "hole" section.

The last two categories define parts of the address space that can be optionally elastic–they expand or contract to take up slack or provide space for neighboring sections. This is controlled by the "elasticity" argument.

Note that when elasticity is ELASTIC_HOLE we simply ignore the "hole" sections, effectively removing their addresses from the range of addresses under consideration. This avoids complications that arise when a "hole" overlaps with a real section (due to someone changing offsets in an incompatible manner), but causes the hole offset and size to remain fixed. (FIXME RPM 2008-10-20)

When section S is shifted by 'Sa' bytes and/or enlarged by 'Sn' bytes, other sections are affected as follows:

  • Cat L: Not affected
  • Cat R: Shifted by Sa+Sn if they are in neighborhood(S). Otherwise the amount of shifting depends on the size of the hole right of neighborhood(S).
  • Cat C: Shifted Sa and enlarged Sn.
  • Cat O: If starting address are the same: Shifted Sa. If starting address not equal: Englarged Sa+Sn
  • Cat I: Shifted Sa, not enlarged
  • Cat B: Not shifted, but enlarged Sn
  • Cat E: Shifted Sa and enlarged Sn

Generally speaking, the AddressSpace argument should be SgAsmGenericFile::ADDRSP_ALL in order to adjust both file and memory offsets and sizes in a consistent manner.

To change the address and/or size of S without regard to other sections in the same file, use set_offset() and set_size() (for file address space) or set_mapped_preferred_rva() and set_mapped_size() (for memory address space).

Adds a new header to the file.

This is called implicitly by the header constructor

void SgAsmGenericFile::remove_header ( SgAsmGenericHeader )

Removes a header from the header list in a file.

SgAsmGenericHeader* SgAsmGenericFile::get_header ( SgAsmExecutableFileFormat::ExecFamily  )

Returns the header for the specified format.

const char* SgAsmGenericFile::format_name ( ) const

Return a string describing the file format.

This uses the last header so that files like PE, NE, LE, LX, etc. which also have a DOS header report the format of the second (PE, etc.) header rather than the DOS header.

virtual void SgAsmGenericFile::destructorHelper ( )
overrideprotectedvirtual

This gets called by all Rosebud-generated destructors.

Rosebud generates a call to destructorHelper from every destructor implementation. This gives the user a chance to do something special. There are some things to be aware of when reimplementing this function, and you should be well versed in the C++ rules about calling virtual functions from destructors.

  • The implementation must not attempt to access any data members of derived classes. These data members have already been destroyed by time this function is called.
  • Any calls you make to virtual functions declared in this class will dispatch only to implementations in this class or its base classes, not any derived classes.
  • Your implementation must expect to be called multiple times for the same object. This occurs when this class implements this function but its derived class does not. During destruction of a derived object, the derived class's Rosebud-generated destructor will call destructorHelper, which will dispatch to the implementation in this class. Then, when the part of the object corresponding to this class is being destroyed, the destructor will call destructorHelper again, which will dispatch to this implementation again. This may happen recursively mutliple times.
  • Your implementation should not destroy anything that a subclass might need during its destruction. This follows from the rule above, but is generally not a problem in practice. The reason it's not a problem is that the derived classes are usually Rosebud-generated and thus their destructors only call destructorHelper. Therefore, in order for any derived class to any work, it must be done in its destructorHelper, which would be called before the implementation of destructorHelper in this class is called.

All attempts should be made to avoid having to implement a destructorHelper in any class but the most base class (and that one does nothing). Instead, use data members whose own destructors do their cleanup. For instance, if this class needs a pointer to data allocated on the stack, then instead of using a raw pointer which needs to be deleted in this class's destructor, use a smart pointer whose own destructor deletes the data. If you follow this advice, then you don't need to be well-versed in the details of C++ object destruction.

Reimplemented from SgNode.

void SgAsmGenericFile::initializeProperties ( )
protected

Initialize all properties that have explicit initial values.

This function is mostly for use in user-defined constructors where the user desires to initialize all the properties but does not know the names of the data members that store the property values. This function initializes the properties that have explicit initializations within this class, but does not recursively initialize base classes.
