Frida 7.1 Released

Frida 7.1 Released ∞

release

04 Apr 2016

If you’ve ever used Frida to spawn programs making use of stdio you might have been frustrated by how the spawned process’ stdio state was rather undefined and left you with very little control. Starting with this release we have started addressing this, and programs are now always spawned with stdin, stdout and stderr redirected, and you can even input your own data to stdin and get the data being written to stdout and stderr. Frida’s CLI tools get this for free as this is wired up in the ConsoleApplication base-class. If you’re not using ConsoleApplication or you’re using a different language-binding, simply connect to the output signal of the Device object and your handler will get three arguments each time this signal is emitted: pid, fd, and data, in that order. Hit the input() method on the same class to write to stdin. That’s all there is to it.

Now that we have normalized the stdio behavior across platforms, we will later be able to add API to disable stdio redirection.

Beside this and lots of bug-fixes we have also massively improved the support for spawning plain programs on Darwin, on both Mac and iOS, where spawn() is now lightning fast on both and no longer messes up the code-signing status on iOS.

For those of you doing advanced instrumentation of Mac and iOS apps there’s now also brand new API for dynamically creating your own Objective-C protocols at runtime. We already supported creating new classes and proxy objects, and with this new API you can do even more.

So in closing, here’s a summary of the changes:

7.1.0:

core: add Device.input() API for writing to stdin of spawned processes
core: add Device.output signal for propagating output from spawned processes
core: implement the new spawn() stdio behavior in the Windows, Darwin, and Linux backends
core: downgrade to Capstone 3.x for now due to non-trivial regressions in 4.x
node: add support for the new stdio API
node: add missing return to error-path
python: add support for the new stdio API

7.1.1:

core: fix intermittent crash in spawn()

7.1.2:

core: rework the spawn() implementation on Darwin, now much faster and reliable
core: add support for enumerating and looking up dynamic symbols on Darwin
core: fix page size computation in the Darwin Mach-O parser

7.1.3:

core: revert temporary hack

7.1.4:

python: fix ConsoleApplication crash on EOF
frida-trace: flush queued events before exiting

7.1.5:

frida-repl: improve REPL autocompletion
objc: add ObjC.registerProtocol() for dynamic protocol creation
objc: fix handling of class name conflicts
objc: allow proxies to be named

7.1.6:

python: fix setup.py download fallback

7.1.7:

python: improve the setup.py download fallback

7.1.8:

python: fix the setup.py local fallback and look in home directory instead

7.1.9:

core: fix handling of overlapping requests to attach to the same pid
core: (Darwin) fix spawn() without attach()
core: (Darwin) fix crash when shutdown requests overlap
frida-server: always recycle the same temporary directory

7.1.10:

core: (Windows) upgrade from VS2013 to VS2015
node: add prebuild for Node.js 6.x
python: fix handling of unicode command-line arguments on Python 2.x
qml: use libc++ instead of libstdc++ on Mac

7.1.11:

core: provide a proper error message when the remote Frida is incompatible
core: ignore attempts to detach from the system session
core: guard against create_script() and detach() overlapping
core: fix setTimeout() so the delay is optional and defaults to 0
core: (V8 runtime) fix crash when closed File object gets GCed
core: (Darwin) fix intermittent crash on teardown
core: (QNX) fix implementation of gum_module_find_export_by_name()
core: (QNX) implement temporary TLS storage
frida-repl: monitor the loaded script and auto-reload on change
node: take level into account when handling log messages so console.warn() and console.error() go to stderr instead of stdout
node: do not let sessions keep the runtime alive

7.1.12:

core: fix the return value of Memory.readByteArray() for size = 0

7.1.13:

core: (Linux/Android) fix export address calculation for libraries with a preferred base
core: fix Java API not available error on Android 6.0
java: improve ART support by taking OS version and arch into account
frida-repl: add –no-pause to not pause spawned process at startup

Enjoy!
