[PATCH] rpm-5.4.14: disable external key server

[PATCH] rpm-5.4.14: disable external key server

[rongqing.li]

From: yzhu1 <yanjun.zhu@windriver.com>

When rpm makes header verification, rpm will send request to the
extern server, this is a potential risk.

Just to explain what this is.  When RPM experiences a signed package, with a
signature that it does NOT know.  By default it will send the -fingerprint- (and
only the 16 digit fingerprint) to an external HKP server, trying to get the key
down.

This is probably not a reasonable default behavior for the system to do, instead
it should simply fail the key lookup.  If someone wants to enable the HKP server
it's easy enough to do by enabling the necessary macros.
