Crate libcasr

LibCASR

LibCASR provides API for parsing stacktraces, collecting crash reports, triaging crashes (deduplication and clustering), and estimating severity of crashes.

It can analyze crashes from different sources:

• AddressSanitizer
• Gdb output

and program languages:

• C/C++
• Rust
• Go
• Python

It could be built with exploitable feature for severity estimation crashes collected from gdb. To save crash reports as json use serde feature.

Modules

• asan
  Asan module implements ParseStacktrace, Exception and Severity traits for AddressSanitizer reports.
• constants
  Constants for signals and stack trace filtering.
• cpp
  Cpp module implements Exception trait for C++ exception messages.
• error
  A custom Casr error.
• exception
  Provides Exception trait.
• execution_class
  Execution_class module contains the ExecutionClass structure which holds an information about crash severity. CLASSES holds raw instances of ExecutionClass structure.
• gdb
  Gdb module implements ParseStacktrace, Exception and Severity traits for Gdb output.
• go
  Go module implements ParseStacktrace and Exception traits for Go panic output.
• python
  Python module implements ParseStacktrace and Exception traits for Python reports.
• report
  Report contains the main struct CrashReport with all information about crash.
• rust
  Rust module implements Exception traits for Rust panic messages.
• severity
  Provides Severity trait.
• stacktrace
  Provides API’s for parsing, filtering, deduplication and clustering.

Macros

• init_ignored_frames
  This macro updates variables used to remove trusted functions from stack trace
