From 8df0bcc69652974def6b12848a4639c7f0a81526 Mon Sep 17 00:00:00 2001 From: Tom Lane Date: Thu, 19 Oct 2006 17:26:51 +0000 Subject: [PATCH] Work around reported problem that AIX's getaddrinfo() doesn't seem to zero sin_port in the returned IP address struct when servname is NULL. This has been observed to cause failure to bind the stats collection socket, and could perhaps cause other issues too. Per reports from Brad Nicholson and Chris Browne. --- src/backend/libpq/ip.c | 11 ++++++++++- 1 file changed, 10 insertions(+), 1 deletion(-) diff --git a/src/backend/libpq/ip.c b/src/backend/libpq/ip.c index 33f0832b93..ee3605db59 100644 --- a/src/backend/libpq/ip.c +++ b/src/backend/libpq/ip.c @@ -8,7 +8,7 @@ * * * IDENTIFICATION - * $Header: /cvsroot/pgsql/src/backend/libpq/ip.c,v 1.23.2.2 2004/11/08 01:54:58 tgl Exp $ + * $Header: /cvsroot/pgsql/src/backend/libpq/ip.c,v 1.23.2.3 2006/10/19 17:26:51 tgl Exp $ * * This file and the IPV6 implementation were initially provided by * Nigel Kukard , Linux Based Systems Design @@ -77,6 +77,15 @@ getaddrinfo_all(const char *hostname, const char *servname, return getaddrinfo_unix(servname, hintp, result); #endif +#ifdef _AIX + /* + * It seems AIX's getaddrinfo doesn't reliably zero sin_port when servname + * is NULL, so force the issue. + */ + if (servname == NULL) + servname = "0"; +#endif + /* NULL has special meaning to getaddrinfo */ return getaddrinfo((!hostname || hostname[0] == '\0') ?
