2.2.1
Highlights
-
T3377 - Fixed a disassembler issue:
- In Axion trace view,
jmp
andcall
instructions would sometimes display the wrong target address. - In the Analysis Python API, the
Instruction
object would sometimes contain wrong operands for relativejmp
andcall
instructions.
Due to this fix, you may observe longer replay duration for the PC range and stack events resources.
- In Axion trace view,
-
Made it impossible to start non-leaf QEMU snapshots. This fixes an issue where starting such snapshots would corrupt their child snapshots.
Improvements
Analysis Python API
- Improved the performance of the
Context.read
method up to x3 in typical workloads. - Added a
timeout
argument to theString.memory_accesses
method, allowing to specify how long this function should attempt to recover all accesses before raising an exception.
Project Manager
-
It is now possible to rename scenarios from the Project Manager web interface. As a result of this change, the name of scenarios must now be unique.
Important: If you already have scenarios that share the same name, they will be renamed upon installation by adding a suffix containing a number to all scenarios sharing the same name. The suffix is
2.2.1-renamed-
number. -
The
snapshots > read
endpoint of the REST API now adds a list of the live QEMU snapshots in the details of the snapshot. This is useful when doing automatic recording. -
Starting a QEMU snapshot session with more than 2048MB of RAM is now allowed. RAM must not exceed 3072MB on a QEMU snapshot session to record scenarios.
Fixed issues
Analysis Python API
- T3378 - Modified
Stack.backtrace
property so that it returns a string instead of printing it. - T3388 - Made the
if
register accessible from the Analysis Python API. Previously, attempting to accessreven2.arch.x64.if
would raise aSyntaxError
, becauseif
is a Python keyword. The register is accessible throughreven2.arch.x64.if_
.
Project Manager
- Fixed starting Axion and the VM in the browser when a SSH X forwarding connection is open.
