Siddhesh Poyarekar 5a4c6d53f5 Get canonical name in getaddrinfo from hosts file for AF_INET (fixes 16077)
AF_INET lookup in hosts file uses _nss_files_gethostbyname2_r, which
is not capable of returning a canonical name if it has found one.
This change adds _nss_files_gethostbyname3_r, which wraps around
_nss_files_gethostbyname2_r and then returns result.h_name as the
canonical name.

Ulrich Drepper 684ae51599 Implement caching of nscd 2011-10-07 10:06:31 -04:00
Ulrich Drepper 319b9ad4bc Generalize framework to register monitoring of files in nscd
nscd can clear caches when certain files change.  The list of files
was hardcoded so far and worked for nss_files and nss_dns and those
modules which need no monitoring.  nss_db, for instance, has its
own set of files to monitor.  Now the NSS modules themselves can
request that certain files are monitored.

Ulrich Drepper 9f2da732e7 Add initgroups lookups to nss_db 2011-06-15 21:06:19 -04:00
Ulrich Drepper 2666d441c2 Reenable nss_db with a completely new implementation
No longer is Berkeley db used.  Instead a simple hash function is used.
The database files are not updated once they are created and therefore
no complicated database is needed.
