- removed some dead code
- dns_zone_setdbtype is now void as it could no longer return
anything but ISC_R_SUCCESS; calls to it no longer check for a result
- controlkeylist_fromconfig() is also now void
- fixed a whitespace error
Commit 9da902a201 removed locking around
the fctx_decreference() call inside resume_dslookup(). This allows
fctx_unlink() to be called without the bucket lock being held, which
must never happen. Ensure the bucket lock is held by resume_dslookup()
before it calls fctx_decreference().
When the unit test is linked with dynamic libraries, the wrapping
doesn't occur, probably because it's different translation unit.
To workaround the issue, we provide thin wrappers with *real* symbol
names that just call the mocked functions.
1. Restore locking in the fctx_decreference() code, because the insides of the
function needs to be protected when fctx->references drops to 0.
2. Restore locking in the dns_resolver_attach() code, because two variables are
accessed at the same time and there's slight chance of data race.
Although the struct dns_resolver.exiting member is protected by stdatomics, we
actually need to wait for whole dns_resolver_shutdown() to finish before
destroying the resolver object. Otherwise, there would be a data race and some
fctx objects might not be destroyed yet at the time we tear down the
dns_resolver object.
This commit changes the BIND cookie algorithms to match
draft-sury-toorop-dnsop-server-cookies-00. Namely, it changes the Client Cookie
algorithm to use SipHash 2-4, adds the new Server Cookie algorithm using SipHash
2-4, and changes the default for the Server Cookie algorithm to be siphash24.
Add siphash24 cookie algorithm, and make it keep legacy aes as
Each individual test opened GeoIP databased but the database handles were never
closed. This commit moves the open/close from the individual unit tests into
the _setup and _teardown methods where they really belong.
