Running a shell command in a child process is generally more useful than simply using theexecsubroutine, as shown in this example. The simplest way to do this is to use thesystemsubroutine. The following is an example of a new-process file that names a program to be run: ...
If the TTS_INSYSCALL bit is set in the event flags, tusc reports which syscall caused the exit.Another example is doing a 'tusc sleep 100' and killing the sleep command with a SIGHUP. Tusc will report:exit(1) [implicit (sigtimedwait failure)]... WIFSIGNALED(SIGHUP)-- Regards, Chris...
I can't reproduce it on a minimal binary but it happened to me before, I zipped the files of an example I have from a recent ctf:thing.zip. I get different behaviours randomly. The reproduce behaviour below should get the exception but continue to main, but it does stop debugging for ...
This is what termux-exec does to circumvent the block on executing files in the data directory - the kernel sees only /system/bin/linker64 being executed. This also means that we need to extract shebangs. So for example, a call to execute: ./path/to/myscript.sh <args> where the scri...
aFigure 7.2 summarizes the activities of the driver as it translates the example program from an ASCII source file into an executable object file. (If you want to see these steps for yourself, run GCC with the-voption.) The driver first runs the C preprocessor (cpp), which translates the...
Tusc reports an "implicit" exit when it gets an EXIT event but the syscall that resulted in the exit is not an exit syscall. If the TTS_INSYSCALL bit is set in the event flags, tusc reports which syscall caused the exit.Another example is doing a 'tusc sleep 100' and killing the sl...
