Query regarding core dump file in linux

[Bibek1602]

Hi All,

We know that core dump files are generated when a process crashes.
I want to know that if we ourselves create dump files when a process is healthy and running and save it in some location , then can we start the process again from the point when the dump file was created by using the information in the dump file ?

And what all information is actually saved in the dump file regarding the process ??

Any help is greatly appreciated..Thanks

Hmmm... not sure if this is what you're after: core(5): core dump file - Linux man page

See "piping core dumps to a program"

Not sure if I read that properly but piping a core dump to a program seems like a vulnerability.

If an intruder writes a program that simply crashes itself and then uses the pipe command to force the program into another program as a root user it could be used to inject something malicious.

Then again I could just be looking at it completely wrong.
