Hi Valerie and Networking guys
Please take a review at this bug fix:
http://cr.openjdk.java.net/~weijun/6578647/webrev.00/
The bug is
http://bugs.sun.com/bugdatabase/view_bug.do?bug_id=6578647
The bug report says that no URL-related info is available in
Authenticator when using HTTP/Negotiate. The reason is that in the long
stack of
HTTP/Negotiate -> JGSS -> JAAS -> Krb5LoginModule
-> Callback -> Authenticator
The URL info is lost. In order to support special actions for
HTTP/Negotiate calls in JGSS (say, using Authenticator instead of
text-based callback, honor the OK-AS-DELEGATE flag...), we already used
an integer field (caller) to tell the codes deep below who initiates the
JGSS calls. It seems an integer is not enough to carry too much
information. (oh, I love the C void*)
The fix is simple: change the caller from integer to a Java class:
GSSCaller, which includes as much as info it likes. For HTTP/Negotiate,
a child class HttpCaller, encapsulates all info an Authenticator needs.
The fix includes three parts:
1. Three new classes:
sun.sec.jgss.GSSCaller:
the new caller
sun.sec.jgss.HttpCaller:
a child of GSSCaller, knows everything about HTTP
sun.net.www.protocol.http.HttpCallerInfo:
the info GSSCaller knows, this class is created on the
network side so that no sun.security.jgss.* codes are
dragged into the bootstrap building process.
2. On the network side:
Refactoring HTTP codes in sun.net.www.protocol.http.* to fill info
into the HttpCallerInfo class.
3. On the JGSS side:
Multiple changes in sun.security.jgss.* classes. *All* the
code changes are simply s/int/GSSCaller/g changes.
I also moved the pre-defined callers from GSSUtil to
GSSCaller.
Thanks
Max
