In EDNS0 records the maximum result size is transmitted in a 16
bit value. Large buffer sizes were handled incorrectly by using

44d20bca52
Implement second fallback mode for DNS requests.
...
There is some more shardware/software out there which has problems
if two DNS requests are sent using the same tuple
(source addr, source port, dest addr, dest port)
This can range from firewalls to load balancers. Some of the vendors
already fixed it in response to this problem. Still, we need a way
to make glibc work with broken environments. The single-request-reopen
flag can be used or we fall back automatically to this mode.
2009-06-26 03:47:47 -07:00
310647e980
Remember we switched to single-request mode.
...
This change prevents repetition in most later calls of the resolver
in case the DNS server or the network connection is broken.
