It looks like it's doing operations on that socket that preeny doesn't intercept. To solve that, you'll need to figure out what functions it's calling (using ltrace
or something) and add them to desock.c
. That's a good place to start, at least.
Thanks for your quick response. I will start my search from there
Hello,
I'm trying to use preeny to be able to fuzz StrongSwan, which is an IPsec implementation. I make use of a named pipe to feed my input to the process (which works with the test case provided by preeny) When enabling debug and starting StrongSwan, it tells me that the following happened (using
desock
):During loading of the process, it does throw a couple of warnings: (from StrongSwan's side):
When I switch to
desock_dup
, it does not respond to any input. Again, it gives me some warnings:I've not been able to figure out what is causing this. I was wondering if you guys have any idea how this can be fixed.
Kind regards, Tom
