resolv: Serialize processing in resolv/tst-resolv-txnid-collision
|
||
|
|
|
||
|
|
When switching name servers, response processing by two server
|
||
|
|
threads clobbers the global test state. (There is still some
|
||
|
|
risk that this test is negatively impact by packet drops and
|
||
|
|
packet reordering, but this applies to many of the resolver tests
|
||
|
|
and is difficult to avoid.)
|
||
|
|
|
||
|
|
Fixes commit f1f00c072138af90ae6da180f260111f09afe7a3 ("resolv:
|
||
|
|
Handle transaction ID collisions in parallel queries (bug 26600)").
