* more docs
* more docu, less clippy
* more fixes
* frida_asan: Implemented initial asan runtime library
* frida_asan: Switch to hashbrown
* Implemented GOT-based hooking to isolate the hooking of the memory functions. Implemented initial ASAN instrumentation
* WIP: Shadowing all used memory. Currently tracking pages using a BTreeSet. Slow AF!
* Add SigTrap to unix_signals and inprocess
* Working frida-asan, almost no speed degradation.
Currently the shadow check is reversed, so it checks only that the shadow is not 0.
We need to implement sub-8-byte checking.
* Format
* Cleanup and formatting
* Sub-qword and 16-byte checks implemented; Fixed unaligned access to QWORD
* Pass the ucontext_t to signal handlers. Initial regdump on crash
* Fix typo
* Make the context argument a mut ref
* Add missing files; Implement initial reporting
* Refactor out gothook; Move safety checkers to dynasm
* Get rid of const assembly blobs no longer needed
* Move to a handler function instead of using SIGTRAP.
This bloats the transformed code, but doesn't seem to have a major impact on performance.
Also, implemented pretty backtraces and assembly output.
* Formatting
* Get rid of all the pinning crap I wasted my day on, We don't need it
* windows fixes
* ashmem
* ashmem_service: server side ready
* ashmem_service: client side ready. Ready for integration
* ashmem_service: changes to UnixShMem to make it 'threadable'
* ashmem_service: format
* ashmem_service: Undo changes to UnixShMem, make the thread own the AshmemService instead; Fix protocol bug
* ashmem_service: working ashmem service. Fix merge issues
* use the newly released capston e 0.8.0; Fix a nasty bug where the afl_area an pc_pointer were reversed. Changed Vectors to Boxed [u8]
* Implement type detection for reporting; Implement double-free/unallocated free checking
* fmt
* Cleanup code a little
* frida-asan: This is an omnibus commit. Should probably have been a bunch of small commits, but I don't have the time/patience.
- Implemented DrCov support in order to debug a failing harness. This is actually
generic and should be moved out of libafl_frida.
- Implemented LIBAFL_FRIDA_OPTIONS env var to pass options to the frida helper,
to dynamically enable/disable asan and drcov.
- Implemented memory reuse - after each test case the used pages are recycled and
can be reused in the next test case.
- Implemented and tested vectorized instruction instrumentation.
- Implemented not instrumenting atomic load/store instructions. The cost of
trying to emulate their behaviour is too high at the moment.
- Implemented probing of shadow bit to determine the best match for the current
system.
- Implemented shadow memory pre-mapping where it is available. We probe for this
too.
- Implemented ability to specify a list of modules to instrument on the command
line. This allows fine-grained control of which modules are instrumented for
coverage/asan/drcov.
- Implemented unpoisoning of the Input target_bytes in a pre_exec hook.
- Added support for zero-sized allocations. We return 0x10 bytes at the moment.
- Added all known operator new/delete functions to hooks.
- Added workaround for frida_gum_allocate_near bug.
- Cleaned up reporting, added reporting for different error types.
