/bin/sh: 0: Illegal option -p

[owl4ce]

I guess -p only available on bash, zsh, ksh. If using dash, you only need remove the -p option. Needs to clarify.

CVE-2021-4034/pwnkit.c

Line 10 in 87ebfb4

char * const args[] = { "/bin/sh", "-pi", NULL };

Probably we can add something to the Makefile (e.g. a check) to set a global variable.

I've pushed a patch which does that to the branch issue-5-illegal-sh-option, it needs some test but I think it can work (if all the shells supports -i).

It was just a missing setuid(0); and setgid(0);

Fixed in master. Closing for now.
