Bug ID: 56352
Summary: tomcat-connectors-1.2.39-windows-x86_64-iis does not
resolve worked DNS names
Product: Tomcat Connectors
Version: 1.2.39
Hardware: PC
Status: NEW
Severity: normal
Priority: P2
Component: isapi
Assignee: dev@tomcat.apache.org
Reporter: knst.koli...@gmail.com
Following the "tomcat-connectors-1.2.39-windows-x86_64-iis does not work"
thread on users list, from April 2rd
http://marc.info/?t=139644507500004&r=1&w=2

It boils down to the following:
The following works:
> worker.ajp13w.host=127.0.0.1
The following does not work:
> worker.ajp13w.host=localhost
and connector tries to connect to 0.0.0.0:
jk_open_socket::jk_connect.c (735): connect to 0.0.0.0:8009 failed (errno=49)
------------
Looking at svn history, I see that implementation of method jk_resolve() was
changed in r1529803 for the case when APR library is not available.
Reviewing the code of jk_resolve() in jk_connect.c, I see the following issue:
line 484
[[[
freeaddrinfo(ai_list);
...
memcpy(&(saddr->sa), ai->ai_addr, ai->ai_addrlen);
]]]
The "ai" variable is a pointer to the chosen item in "ai_list" linked list of
addresses returned by getaddrinfo(). The bug is that freeaddrinfo(ai_list) is
called too early, before the information is copied away.
Also, the following on lines 436-441:
[[[
#if JK_HAVE_IPV6
if (prefer_ipv6)
hints.ai_family = JK_INET6;
else
#endif
hints.ai_family = JK_INET;
]]]
As "hints" is a structure that is passed to getaddrinfo() method, I would
expect those assignments to use AF_INET, AF_INET6. I suspect that this is
non-issue, as those defines should be defined as equal to AF_xx constants
anyway, but other code later uses AF_xx constants, so I expect the AF_xx ones
to be used here as well.
("if (ai->ai_family == AF_INET6)")
