>>>

bulk_modify_symbols()[source]¶: bulk_modify_symbols returns a context manager that improves performance when adding or removing a large number of symbols. Symbols added within the Python with keyword will defer processing until the end of the block. Many symbol getter APIs will return stale results inside the with block, so this function should only be used when symbol queries are not needed at the same time as the modifications.

find_all_constant searches for the integer constant constant starting at the virtual address start until the virtual address end. Once a match is found, the match_callback is called.

Note

A constant is considered used if a line in the linear view expansion of the given function graph type contains a token with a value that matches that constant. This does not search for raw bytes/data in the binary, for that you want to use find_all_data.

Parameters:

start (int) – virtual address to start searching from.
end (int) – virtual address to end the search.
constant (int) – constant to search for
settings (DisassemblySettings) – DisassemblySettings object used to render the text to be searched
graph_type (FunctionGraphType) – the IL to search within
progress_func (callback) – optional function to be called with the current progress and total count. This function should return a boolean value that decides whether the search should continue or stop
match_callback (callback) – function that gets called when a match is found. The callback takes two parameters, i.e., the address of the match, and the LinearDisassemblyLine that contains the matching line. If this parameter is None, this function becomes a generator and yields the matching address and the matching LinearDisassemblyLine. This function can return a boolean value that decides whether the search should continue or stop

This may have the impact of loading other type libraries as dependencies on other type libraries are lazily resolved when references to types provided by them are first encountered.

Note

If you are implementing a custom BinaryView and use this method to import object types, you should then call record_imported_object with the details of where the object is located.

Parameters:

name (QualifiedName) –

Returns:

the object type, with any interior NamedTypeReferences renamed as necessary to be appropriate for the current view

Return type:

Note that the name actually inserted into the view may not match the name as it exists in the type library in the event of a name conflict. To aid in this, the Type object returned is a NamedTypeReference to the deconflicted name used.

Parameters:

name (QualifiedName) –
lib (TypeLibrary) –

Returns:

a NamedTypeReference to the type, taking into account any renaming performed

load opens, generates default load options (which are overridable), and returns the first available BinaryView. If no BinaryViewType is available, then a Mapped BinaryViewType is used to load the BinaryView with the specified load options. The Mapped view type attempts to auto-detect the architecture of the file during initialization. If no architecture is detected or specified in the load options, then the Mapped view type fails to initialize and returns None.

Note

Although general container file support is not complete, support for Universal archives exists. It’s possible to control the architecture preference with the ‘files.universal.architecturePreference’ setting. This setting is scoped to SettingsUserScope and can be modified as follows

>>> Settings().set_string_list("files.universal.architecturePreference", ["arm64"])

It’s also possible to override the ‘files.universal.architecturePreference’ user setting by specifying it directly with load. This specific usage of this setting is experimental and may change in the future

>>> bv = binaryninja.load('/bin/ls', options={'files.universal.architecturePreference': ['arm64']})

Warning

The recommended code pattern for opening a BinaryView is to use the load API as a context manager like with load('/bin/ls') as bv: which will automatically clean up when done with the view. If using this API directly you will need to call bv.file.close() before the BinaryView leaves scope to ensure the reference is properly removed and prevents memory leaks.

Parameters:

source (Union[str, bytes, bytearray, DataBuffer, PathLike, BinaryView]) – path to file/bndb, raw bytes, or raw view to load
update_analysis (bool) – whether or not to run update_analysis_and_wait after opening a BinaryView, defaults to True
progress_func (callback) – optional function to be called with the current progress and total count
options (dict) – a dictionary in the form {setting identifier string : object value}
source –

Returns:

returns a BinaryView object for the given filename or None

Return type:

BinaryView or None

Example:

>>> binaryninja.load('/bin/ls', options={'loader.imageBase': 0xfffffff0000, 'loader.macho.processFunctionStarts' : False})
<BinaryView: '/bin/ls', start 0xfffffff0000, len 0xa290>

parse_expression(expression: str, here: int = 0) → int[source]¶

Evaluates a string expression to an integer value.

The parser uses the following rules:

Symbols are defined by the lexer as [A-Za-z0-9_:<>][A-Za-z0-9_:$\-<>]+ or anything enclosed in either single or double quotes

Symbols are everything in bv.symbols, unnamed DataVariables (i.e. data_00005000), unnamed functions (i.e. sub_00005000), or section names (i.e. .text)

Numbers are defaulted to hexadecimal thus _printf + 10 is equivalent to printf + 0x10 If decimal numbers required use the decimal prefix.

Since numbers and symbols can be ambiguous its recommended that you prefix your numbers with the following:

0x - Hexadecimal

0n - Decimal

0 - Octal

In the case of an ambiguous number/symbol (one with no prefix) for instance 12345 we will first attempt to look up the string as a symbol, if a symbol is found its address is used, otherwise we attempt to convert it to a hexadecimal number.

The following operations are valid: +, -, \*, /, %, (), &, \|, ^, ~, ==, !=, >, <, >=, <=

Comparision operators return 1 if the condition is true, 0 otherwise.

In addition to the above operators there are dereference operators similar to BNIL style IL:

[<expression>] - read the current address size at <expression>

[<expression>].b - read the byte at <expression>

[<expression>].w - read the word (2 bytes) at <expression>

[<expression>].d - read the dword (4 bytes) at <expression>

[<expression>].q - read the quadword (8 bytes) at <expression>

The $here (or more succinctly: $) keyword can be used in calculations and is defined as the here parameter, or the currently selected address

The $start/$end keyword represents the address of the first/last bytes in the file respectively

Arbitrary magic values (name-value-pairs) can be added to the expression parser via the add_expression_parser_magic_value API. Notably, the debugger adds all register values into the expression parser so they can be used directly when navigating. The register values can be referenced like $rbp, $x0, etc. For more details, refer to the related [debugger docs](https://docs.binary.ninja/guide/debugger.html#navigating-the-binary).

Parameters:

expression (str) – Arithmetic expression to be evaluated
here (int) – (optional) Base address for relative expressions, defaults to zero

Return type:

parse_possiblevalueset(value: str, state: RegisterValueType, here: int = 0) → PossibleValueSet[source]¶

Evaluates a string representation of a PossibleValueSet into an instance of the PossibleValueSet value.

Note

Values are evaluated based on the rules as specified for parse_expression API. This implies that a ConstantValue [0x4000].d can be provided given that 4 bytes can be read at 0x4000. All constants are considered to be in hexadecimal form by default.

The parser uses the following rules:

ConstantValue - <value>
ConstantPointerValue - <value>
StackFrameOffset - <value>
SignedRangeValue - <value>:<value>:<value>{,<value>:<value>:<value>}* (Multiple ValueRanges can be provided by separating them by commas)
UnsignedRangeValue - <value>:<value>:<value>{,<value>:<value>:<value>}* (Multiple ValueRanges can be provided by separating them by commas)
InSetOfValues - <value>{,<value>}*
NotInSetOfValues - <value>{,<value>}*

Parameters:

value (str) – PossibleValueSet value to be parsed
state (RegisterValueType) – State for which the value is to be parsed
here (int) – (optional) Base address for relative expressions, defaults to zero

Return type:

PossibleValueSet

Example:

>>> psv_c = bv.parse_possiblevalueset("400", RegisterValueType.ConstantValue)
>>> psv_c
<const 0x400>
>>> psv_ur = bv.parse_possiblevalueset("1:10:1", RegisterValueType.UnsignedRangeValue)
>>> psv_ur
<unsigned ranges: [<range: 0x1 to 0x10>]>
>>> psv_is = bv.parse_possiblevalueset("1,2,3", RegisterValueType.InSetOfValues)
>>> psv_is
<in set([0x1, 0x2, 0x3])>
>>>

parse_type_string(text: str) → Tuple[Type, QualifiedName][source]¶

parse_type_string parses string containing C into a single type Type. In contrast to the parse_types_from_source or parse_types_from_source_file, parse_type_string can only load a single type, though it can take advantage of existing type information in the binary view, while those two APIs do not.

Parameters:

text (str) – C source code string of type to create

Returns:

A tuple of a Type and type name

Return type:

tuple(Type, QualifiedName)

Example:

>>> bv.parse_type_string("int foo")
(<type: int32_t>, 'foo')
>>>

parse_types_from_string(text: str, options: Optional[List[str]] = None, include_dirs: Optional[List[str]] = None) → TypeParserResult[source]¶

parse_types_from_string parses string containing C into a TypeParserResult objects. This API unlike the parse_types_from_source allows the reference of types already defined in the BinaryView.

Parameters:

text (str) – C source code string of types, variables, and function types, to create
options (Optional[List[str]]) – Optional list of string options to be passed into the type parser
include_dirs (Optional[List[str]]) – Optional list of header search directories

Returns:

TypeParserResult (a SyntaxError is thrown on parse error)

Return type:

TypeParserResult

Example:

>>> bv.parse_types_from_string('int foo;\nint bar(int x);\nstruct bas{int x,y;};\n')
({types: {'bas': <type: struct bas>}, variables: {'foo': <type: int32_t>}, functions:{'bar':
