[Fixes#38426061, #38097411]
Msf::Modules::Loader::Directory#read_module_content may calculate a non-existent
module_path that gets passed to File.open causing an Errno::ENOENT exception
to be raised when using the module cache with a module that has been
moved to a new path (as is the case that originally found this bug) or
deleted. Now, the exception is rescued and read_module_content returns
an empty string (''), which load_module detects with
module_content.empty? and returns earlier without attempting to module
eval the (empty) content.
As having Msf::Modules::Loader::Directory#read_module_content rescue the
exception, meant there was another place that needed to log and error
and store an error in Msf::ModuleManager#module_load_error_by_path, I
refactored the error reporting to call
Msf::Modules::Loader::Base#load_error, which handles writing to the log
and setting the Hash, so the error reporting is consistent across the
loaders.
The exception hierarchy was also refactored so that
namespace_module.metasploit_class now has an error raising counter-part:
namespace_module.metasploit_class! that can be used with
Msf::Modules::Loader::Base#load_error as it requires an exception, and
not just a string so the exception class, message, and backtrace can be
logged.
Msf::Modules::Loader::Archive#each_module_reference_name tried to check
the enabled types for the module_manager by accessing the
enabledment_by_type Hash, which is protected. Instead, it should use
the public type_enabled? method.
Add specs to test all of Msf::Modules::Loader::Archive while testing
each_module_reference_name. In order to properly test that modules
could be found in archives, I had to produce a fastlib archive, so there
is now a spec for FastLib.dump and FastLib.load. Some specs are marked
pending as I found a bug in FastLib, which has a work-around. The bug
is filed in PivotalTracker as
https://www.pivotaltracker.com/story/show/38730815 and the pending tests
include the URL also in their tags.
[Fixes#37630057]
Modules were always being detected as having file changes because the
parent_path directory, instead of the actual module_path, was being
passed to module_manager.file_changed?, which caused the modification
times to not match.
To ensure this change fixes the ambiguous module warnings, a full spec
for Msf::Core::Modules::Loader::Base has been written.
spec/msf has moved to spec/lib/msf to match conventional spec layout and
allow for the spec/support directory to not be confused as a lib
subdirectory being tested.
