Bug summary: [RHEL4] getnameinfo() should return EAI_NONAME when both nodename and servname are set to null and flag is set to NI_NAMEREQD
|

Description:
|
|
|
|
+++ This bug was initially created as a clone of Bug #489419 +++
|
|
|
|
Description of Problem:
|
|
glibc getnameinfo() returns 0 when both nodename and servname are set to null and flag is set to 'NI_NAMEREQD'.
|
|
|
|
The synopsis of function getnameinfo is:
|
|
int getnameinfo(const struct sockaddr *sa, socklen_t salen, char *node, socklen_t nodelen, char *service, socklen_t servicelen, int flags);
|
|
|
|
RFC3493 tells that getnameinfo() should returns 'EAI_NONAME' when both nodename and servname are null. So when use getnameinfo() with both nodename and servname are null and the NI_NAMEREQD flag is set, glibc should return 'EAI_NONAME' rather than 0.

Version-Release number of selected component:

How reproducible:

2. ./a.out

|
<=== NG ===>
