Subject: [PATCH] Adjust jitterentropy library to timeout/fail on long delay
|
||
|
|
|
||
|
|
[Bernd: removed description of unrelated part of the patch]
|
||
|
|
|
||
|
|
Also while we're at it, I might have a build solution for the presence
|
||
|
|
of internal timers. When jitterentropy is built without internal
|
||
|
|
timers, jent_notime_init is defined publically, but when it is built
|
||
|
|
with timers, its declared as a static symbol, preenting resolution, so
|
||
|
|
we can test to see if the function exists. If it does we _don't_ have
|
||
|
|
notime support. The logic is a bit backwards, but i think it works
|
||
