Patch to add a --enable-pie option to unbound's configure
In order to fully benefit from ASLR, unbound would need to be compiled as a Position-Independent Executable. While building as PIE may not be desirable by default for performance reason, would you be willing to add a configure option to do so? It would make it easier to build as PIE without the need to set custom CFLAGS/LDFLAGS, like Hardened Gentoo or Debian's hardening-wrapper are doing.
Attached is a proposal to add such an option. Due to my lack of experience with autotools, I am not sure it is the best way to add such an option though.
Thank you for your patch. It is well written, and I have integrated it. (also in NSD!). I hope this can increase the security of the server.
Best regards, Wouter
