2012-11-19Return EAI_SYSTEM if we're out of file descriptorsSiddhesh Poyarekar
Resolves BZ #14719.
2012-10-30Suppress incorrect link warnings for NSS symbolsChris Metcalf
When glibc is built with --enable-static-nss, the warning that using NSS symbols requires the nss shared objects to be present is no longer true, as those symbols are built into libc. Suppress the warning for those symbols by providing a new macro (nss_interface_function) for the NSS functions that is defined as static_link_warning in the normal case, and empty for static NSS.
2012-09-28 [BZ #11438]Jeff Law
* sysdeps/posix/getaddrinfo.c (default_scopes): Map RFC 1918 * addresses to global scope. * posix/tst-rfc3484.c: Verify 10/8, 172.16/12 and 196.128/16 addresses are in the same scope as 192.0.2/24. * posix/gai.conf: Document new scope table defaults.
2012-08-22 * sysdeps/posix/getaddrinfo.c (gaih_inet): Only use gethostbyname4_rJeff Law
if the family is PF_UNSPEC.

2012-07-12Avoid duplicate DNS requests if answer is longer than a implementationJeroen van Bemmel
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).

2011-11-15Clean up internal fopen usesUlrich Drepper
No need to ever not use c and e.
2011-10-31Cache network interface informationUlrich Drepper
Whenever getaddrinfo needed network interface information it used the netlink interface to read the information every single time. The problem is that this information can change at any time. The patch implements monitoring of the network interfaces through nscd. If no change is detected the previously read information can be reused (which is the norm). This timestamp information is also made available to other processes using the shared memory segment between nscd and those processes.
2011-08-04Fix encoding name for IDN in getaddrinfoAndreas Schwab
2011-06-30Make sure RES_USE_INET6 is always restoredAndreas Schwab
2011-06-22Avoid __check_pf calls in getaddrinfo unless really neededUlrich Drepper
2011-06-22Fix Ipv4&IPv6 lookup in getaddrinfoAndreas Schwab
Problem introduced in the last patch.
2011-06-21Fix IPv6-only lookups through getaddrinfoUlrich Drepper
A recent patch introduced a problem where IPv6 lookups happily returned IPv4 addresses.
2011-06-21Minor optimization of getaddrinfo after recent patchUlrich Drepper
2011-06-13Fix memory leak in getaddrinfoUlrich Drepper
2011-05-29Restore _res correctlyUlrich Drepper
getaddrinfo works around the resolver functionality to avoid automatic IPv6 lookups. The restoring didn't allow for the resolver to set additional bits in _res.
2011-05-20Don't unconditionally use alloca in gaih_inetUlrich Drepper
2011-05-02getaddrinfo(AF_INET6) does not return scope_id info provided by NSS modulesMaciej Babinski
2011-01-19Fix decoding of canonical name in getaddrinfo.Ulrich Drepper
2010-08-11Add self-contained test for NSS.Ulrich Drepper
While at it fix interaction between __nss_configure_lookup and nscd. Otherwise the test fails if nscd is runnung.
2010-03-26Fix one case of last checkin.Ulrich Drepper
If the v4 lookup failed but v6 succeeded we treat this as a success.
2010-03-26Don't abort immediately on successful lookup in getaddrinfo.Ulrich Drepper
When not using gethostbyname4 methods we immediately aborted the loop over the nss modules on the first successful lookup. While this is almost always what is wanted the nsswitch.conf file allows to select something different.
2010-03-26Fix spurious UNAVAIL status is getaddrinfoAndreas Schwab
2009-12-10Fix a few error cases in *name4_r lookup handling.Ulrich Drepper

to IPv4 or IPv6 if an interface has been found.
2008-11-27* sysdeps/posix/getaddrinfo.c (getaddrinfo): If the system hasUlrich Drepper

entry is available, believe it.
