* Always use IPv4 sockets for IPv4 addresses.Ulrich Drepper2010-01-141-35/+9
|
* Relax visibility of some more declaration.Ulrich Drepper2010-01-141-2/+2
|
* Relax condition for resolver constant definition.Ulrich Drepper2010-01-141-6/+6
|
* Fix up netdb.h for XPG7.Ulrich Drepper2010-01-121-1/+3
|
* Handle running out of buffer space with IPv6 mapping enabled.Andreas Schwab2009-11-102-9/+9
| | | | | | 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.
* Initialize local variable in resolver.Ulrich Drepper2009-10-291-1/+2
| | | | | When the DNS server doesn't reply at all we possibly tested an unitialized variable.
* Fix mixing IPv4 and IPv6 name server in resolv.conf.Petar Bogdanovic2009-10-291-26/+26
|
* Define and implement RES_USE_DNSSEC option in resolver.Adam Tkac2009-07-274-5/+16
|
* Handle SERVFAIL, NOTIMP, REFUSED replies from DNS server better.Ulrich Drepper2009-07-261-5/+1
| | | | | When doing IPv4+6 lookups we have to pass up the error record from send_dg.
* Handle overly large answer buffers in resolver.Ulrich Drepper2009-07-161-1/+1
| | | | | | 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.
* Implement second fallback mode for DNS requests.Ulrich Drepper2009-06-263-19/+54
| | | | | | | | | | | | 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.
* Remember we switched to single-request mode.Ulrich Drepper2009-06-111-1/+2
| | | | | This change prevents repetition in most later calls of the resolver in case the DNS server or the network connection is broken.
* Remove redundant .gitignore files.Andreas Schwab2009-05-161-6/+0

* rename each .cvsignore file to .gitignoreJim Meyering2009-05-151-0/+0
