VAMOS

VAMOS is a framework containing libraries and a set of tools for monitoring heterogeneous asynchronous events sources. Events are efficiently transferred via concurrent buffers in the shared memory.

The current developement version can be found in the branch dev. Code in the main branch may be highly outdated. If you cannot find something that you think should be here, write to <mchqwerty (at) gmail (dot) com>.

Build:

You can use the setup.sh script for a fast set-up

# git clone ...
cd vamos
python -m venv venv/
source venv/bin/activate

./setup.sh

For a more detailed build with more control over things, you can build everything manually:

# git clone ...
cd vamos
python -m venv venv/
source venv/bin/activate

make [OPTIONS]

OPTIONS may include:

  • BUILD_TYPE=[Debug|Release|RelWithDebInfo] the type of build to pass to cmake
  • LLVM_SOURCES=OFF to turn off building event sources based on instrumentation of LLVM
  • DYNAMORIO_SOURCES=OFF to turn off building event sources based on DynamoRIO
  • DynamoRIO_DIR=<path/to/dynamorio/cmake> to use a particular DynamoRIO build
  • TESSLA_SUPPORT=[ON|OFF] enable support for TeSSLa monitors

The used OPTIONS are stored into Makefile.config and re-used in future make runs. If you want to change the options, either delete the file or change values in there and run make reconfigure && make or make reset && make (warning: the latter will completely clean repositories, including all files that are not under git).

Using

Run source venv/bin/activate from the top-level directory and then run the desired script from one of the sub-repositories. The sub-repositories have their own READMEs.

Components

  • vamos-buffers implementation of shared memory buffers used to transfer events
  • vamos-common common parts shared by multiple VAMOS repositories (mostly python packages)
  • vamos-sources implementation of tracing various standard events in programs (event sources) and a specification language for that
  • vamos-compiler a compiler of the legacy VAMOS specifications
  • vamos-monitors manually written monitors, mostly for debugging and testing purposes
  • vamos-mpt a compiler for multi-trace prefix transducers
