2010-01-14Always use IPv4 sockets for IPv4 addresses.Ulrich Drepper
2010-01-14Relax visibility of some more declaration.Ulrich Drepper
2010-01-14Relax condition for resolver constant definition.Ulrich Drepper
2010-01-12Fix up netdb.h for XPG7.Ulrich Drepper
2009-11-10Handle running out of buffer space with IPv6 mapping enabled.Andreas Schwab
With big DNS answers like the one you get for goodtimesdot.com you can get a truncated address list if IPv6 mapping is enabled. Instead tell the caller to resize the buffer.
2009-10-29Initialize local variable in resolver.Ulrich Drepper
When the DNS server doesn't reply at all we possibly tested an unitialized variable.
2009-10-29Fix mixing IPv4 and IPv6 name server in resolv.conf.Petar Bogdanovic
2009-07-27Define and implement RES_USE_DNSSEC option in resolver.Adam Tkac
2009-07-26Handle SERVFAIL, NOTIMP, REFUSED replies from DNS server better.Ulrich Drepper
When doing IPv4+6 lookups we have to pass up the error record from send_dg.
2009-07-16Handle overly large answer buffers in resolver.Ulrich Drepper
In EDNS0 records the maximum result size is transmitted in a 16 bit value. Large buffer sizes were handled incorrectly by using only the low 16 bits. Fix this by limiting the size to 0xffff.
2009-06-26Implement second fallback mode for DNS requests.Ulrich Drepper
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.
2009-06-11Remember we switched to single-request mode.Ulrich Drepper
This change prevents repetition in most later calls of the resolver in case the DNS server or the network connection is broken.
