[Bug 61080] New: apr_sockaddr_info_get() with hostname is NULL
https://bz.apache.org/bugzilla/show_bug.cgi?id=61080
Bug ID: 61080
Summary: apr_sockaddr_info_get() with hostname is NULL
Product: APR
Version: 1.5.2
Hardware: PC
Status: NEW
Severity: normal
Priority: P2
Component: APR
Assignee: bugs@apr.apache.org
Reporter: a.abfalterer@gmail.com
Target Milestone: ---
Hi,
apr_sockaddr_info_get() does not allow to set the flag (APR_IPV4_ADDR_OK or
APR_IPV6_ADDR_OK) and to pass NULL for the hostname. In this case APR_EINVAL is
returned, see
https://github.com/apache/apr/blob/trunk/network_io/unix/sockaddr.c#L614-L618
However, the documentation says "The hostname [...] or NULL to build an address
that corresponds to 0.0.0.0 or :: [...]", see
https://apr.apache.org/docs/apr/1.6/group__apr__network__io.html#gaa2f399ca2b60b35c0abf7630298c6c9f
Also the manual of getaddrinfo says "If the AI_PASSIVE flag is specified in
hints.ai_flags, and node is NULL, then the returned socket addresses will be
suitable for bind(2)ing a socket that will accept(2) connections. The returned
socket address will contain the "wildcard address" (INADDR_ANY for IPv4
addresses, IN6ADDR_ANY_INIT for IPv6 address). The wildcard address is used by
applications (typically servers) that intend to accept connections on any of
the hosts's network addresses. If node is not NULL, then the AI_PASSIVE flag is
ignored.
If the AI_PASSIVE flag is not set in hints.ai_flags, then the returned socket
addresses will be suitable for use with connect(2), sendto(2), or sendmsg(2).
If node is NULL, then the network address will be set to the loopback interface
address (INADDR_LOOPBACK for IPv4 addresses, IN6ADDR_LOOPBACK_INIT for IPv6
address); this is used by applications that intend to communicate with peers
running on the same host."
Cheers, Armin
