volatility3.plugins.linux.lsof module

class FDInternal(task, fd_fields)[source]

Bases: object

FD internal representation containing only the core objects

Fields:: task: ‘task_struct’ object fd_fields: FD fields as obtained from LinuxUtilities.files_descriptors_for_process()

fd_fields: Tuple[int, int, str]

task: ObjectInterface

to_user()[source]

Augment the FD information to be presented to the user

Return type:: FDUser
Returns:: An InodeUser dataclass

class FDUser(task_tgid, task_tid, task_comm, fd_num, full_path, device=<volatility3.framework.renderers.NotAvailableValue object>, inode_num=<volatility3.framework.renderers.NotAvailableValue object>, inode_type=<volatility3.framework.renderers.NotAvailableValue object>, file_mode=<volatility3.framework.renderers.NotAvailableValue object>, change_time=<volatility3.framework.renderers.NotAvailableValue object>, modification_time=<volatility3.framework.renderers.NotAvailableValue object>, access_time=<volatility3.framework.renderers.NotAvailableValue object>, inode_size=<volatility3.framework.renderers.NotAvailableValue object>)[source]

Bases: object

FD user representation, featuring augmented information and formatted fields. This is the data the plugin will eventually display.

access_time: datetime = <volatility3.framework.renderers.NotAvailableValue object>

class Lsof(context, config_path, progress_callback=None)[source]

Bases: PluginInterface, TimeLinerInterface

Lists open files for each processes.

Parameters:

context (ContextInterface) – The context that the plugin will operate within
config_path (str) – The path to configuration data within the context configuration data
progress_callback (Optional[Callable[[float, str], None]]) – A callable that can provide feedback at progress points

build_configuration()

Constructs a HierarchicalDictionary of all the options required to build this component in the current context.

Ensures that if the class has been created, it can be recreated using the configuration built Inheriting classes must override this to ensure any dependent classes update their configurations too

Return type:: HierarchicalDict

property config: HierarchicalDict: The Hierarchical configuration Dictionary for this Configurable object.

property config_path: str: The configuration path on which this configurable lives.

property context: ContextInterface: The context object that this configurable belongs to/configuration is stored in.

generate_timeline()[source]

Method generates Tuples of (description, timestamp_type, timestamp)

These need not be generated in any particular order, sorting will be done later

classmethod get_requirements()[source]

Returns a list of Requirement objects for this plugin.

Return type:: List[RequirementInterface]

classmethod list_fds(context, vmlinux_module_name, filter_func=<function Lsof.<lambda>>)[source]

Enumerates open file descriptors in tasks

Parameters:

context (ContextInterface) – The context to retrieve required elements (layers, symbol tables) from
vmlinux_module_name (str) – The name of the kernel module on which to operate
filter_func (Callable[[int], bool]) – A function which takes a process object and returns True if the process should be ignored/filtered

Yields:

A FDInternal object

Return type:

Iterable[FDInternal]

classmethod make_subconfig(context, base_config_path, **kwargs)

Convenience function to allow constructing a new randomly generated sub-configuration path, containing each element from kwargs.

Parameters:

context (ContextInterface) – The context in which to store the new configuration
base_config_path (str) – The base configuration path on which to build the new configuration
kwargs – Keyword arguments that are used to populate the new configuration path

Returns:

The newly generated full configuration path

Return type:

str

property open: Returns a context manager and thus can be called like open

run()[source]

Executes the functionality of the code.

Note

This method expects self.validate to have been called to ensure all necessary options have been provided

Returns:: A TreeGrid object that can then be passed to a Renderer.

set_open_method(handler)

Sets the file handler to be used by this plugin.

Return type:: None

classmethod unsatisfied(context, config_path)

Returns a list of the names of all unsatisfied requirements.

Since a satisfied set of requirements will return [], it can be used in tests as follows:

unmet = configurable.unsatisfied(context, config_path)
if unmet:
    raise RuntimeError("Unsatisfied requirements: {}".format(unmet)

Return type:: Dict[str, RequirementInterface]

version = (2, 0, 2)
