* Avoid duplicate DNS requests if answer is longer than a implementationJeroen van Bemmel2012-07-121-4/+0
| | | | | | | | | | | | | | | | limit [BZ #14307] * sysdeps/posix/getaddrinfo.c (gaih_inet): Increase the size of the temporary buffer used to invoke __gethostbyname2_r, __gethostbyaddr_r and gethostbyname4_r to make room for struct host_data / struct gaih_addrtuple. * resolv/nss_dns/dns-host.c (global scope): Move definition of implementation constants MAX_NR_ALIASES and MAX_NR_ADDRS to header file nss/nsswitch.h. * nss/nsswitch.h (global scope): Add definition of implementation constants MAX_NR_ALIASES and MAX_NR_ADDRS (moved from resolv/nss_dns/dns-host.c).

* Consider TTL of CNAME record and return minimum TTL in the chainSiddhesh Poyarekar2012-03-301-3/+18
| | | | | | | | | [BZ #13928] A DNS request consists of multiple resources combined into a single hostent, including multiple CNAME records that may have been assigned different TTL values. In such a case, nscd should take the least TTL among all of the resources as the timeout for the hostent before it is reloaded in its cache so that the hostent remains stale in the database for the least amount of time.
* * resolv/nss_dns/dns-host.c: Update copyright year.Jeff Law2012-03-301-1/+1

* Better error handling for sendmmsg use in res_sendUlrich Drepper2012-03-301-5/+7
|
* Correct check for DNS request send successUlrich Drepper2012-03-301-1/+1
| | | | | | This predates the sendmmsg use. The two requests can use different request sizes but the check for successful transfer always only used buflen.
* Speed up DNS by avoiding a system call if possibleUlrich Drepper2012-03-301-17/+83
|
* [BZ #13760]Jeff Law2012-03-281-1/+7
| | | | | | * resolv/nss_dns/dns-host.c (gaih_getanswer): Look for errno in the right place. Discard and retry query if response is larger than input buffer size.
