96f8a94c19 - Fix for repeated use of a DNAME record: first overallocate and then 
move the exact size of the init value to avoid false positive heap
  overflow reads from address sanitizers.

ff653a7ef8 Call module init init again, and new function startup and destartup. 
NULL can be used if the function is not used. Open shared ports during
reload. Deinit is called during reload.

b624ed5050 - disable-edns-do, validator init prints warning when disable-edns-do is 
turned on, but there are trust anchors, and then turns off disable-edns-do.

d4314cad33 Make VAL_MAX_RESTART_COUNT configurable. 
unbound tries very hard (up to 6 authoritative servers) to find a
validating answer. This is not always desirable, for example on high
latency links.

2c4be0c201 - Fix crash after reload where a stats lookup could reference old key 
cache and neg cache structures.
 2020-01-14 15:18:52 +01:00
Florian Obser
da6ac0c4ff Use passed in neg and key cache if non-NULL. 
With this the neg and key caches can be shared between multiple
libunbound contexts.

The msg and rrset caches already allowed this since context_finalize()
did not touch those if they are already available and have the correct
size.

Care must be taken to properly unhook the caches from the validator
environment before calling ub_ctx_delete() otherwise one risks double
free or use after free bugs.
