2010-01-14Relax condition for resolver constant definition.Ulrich Drepper1-6/+6
2010-01-12Fix up netdb.h for XPG7.Ulrich Drepper1-1/+3
2009-11-10Handle running out of buffer space with IPv6 mapping enabled.Andreas Schwab2-9/+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.
2009-10-29Initialize local variable in resolver.Ulrich Drepper1-1/+2
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 Bogdanovic1-26/+26
2009-07-27Define and implement RES_USE_DNSSEC option in resolver.Adam Tkac4-5/+16
2009-07-26Handle SERVFAIL, NOTIMP, REFUSED replies from DNS server better.Ulrich Drepper1-5/+1
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 Drepper1-1/+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.
2009-06-26Implement second fallback mode for DNS requests.Ulrich Drepper3-19/+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.
2009-06-11Remember we switched to single-request mode.Ulrich Drepper1-1/+2
This change prevents repetition in most later calls of the resolver in case the DNS server or the network connection is broken.
2009-05-16Remove redundant .gitignore files.Andreas Schwab1-6/+0
2009-05-15rename each .cvsignore file to .gitignoreJim Meyering1-0/+0

2009-05-05 Aurelien Jarno <aurelien@aurel32.net> [BZ #10128] * resolv/res_query.c (__libc_res_nquery): If one query returns NOTIMP or FORMERR and the other NOERROR, don't raise an error.
2009-04-16(send_dg): Don't just ignore the result we got in case we only receive one ↵Ulrich Drepper1-6/+10
reply in single-request mode.
2009-04-16* resolv/res_send.c (send_dg): Don't switch into single-requestUlrich Drepper1-1/+3
mode if we already are in it.
2009-04-08* malloc/malloc.c (_int_realloc): Add parameter with old blockUlrich Drepper1-1/+1
size. Remove duplicated test. Don't handle mmap'ed blocks here. Adjust all callers. * malloc/hooks.c (realloc_check): Adjust _int_realloc call.
2009-04-07* resolv/res_hconf.c (_res_hconf_trim_domain): Use strcasecmpUlrich Drepper2-3/+3

2009-04-07* resolv/resolv.h (RES_SNGLKUP): Define.cvs/fedora-glibc-20090407T0545Ulrich Drepper3-11/+30
* resolv/res_init.c (res_setoptions): Recognize single-request option. * resolv/res_send.c (send_dg): If we sent two requests at once and only get one reply before timeout switch to mode where we send the second request only after the first answer has been received.
