Hi Max,
I only looked at the networking part of the changes. They look fine,
I just have a few questions/comments:
1) sun.net.www.protocol.http.HttpURLConnection
Can you use the same HttpCallerInfo instance for proxy
authentication
at line 1108? This instance has been created using the single arg
constructor therefore it is has authType = RequestorType.SERVER,
right?
Yes, you're right. Will update tomorrow.
2) sun.net.www.protocol.http.HttpCallerInfo
It is just my preference, but I would prefer to see all the fields
of
HttpCallerInfo private and have simple accessors:
private final String host;
......
public String host() {
return host;
}
......
Your suggestion is more formal. But I think making all fields final is
also sufficient to make it immutable.
3) Are the changes to use HttpCallerInfo in AuthenticationHeader,
HttpURLConnection, NegotiateAuthentication and NegotiatorImpl
strictly necessary? They seem to be changed just for consistency of
using the new class. I only see that NegotiateCallbackHandler is
required to use this new class on the networking side.
There needs a way to transfer these info into the JGSS underneath (so
that NegotiateCallbackHandler has a chance to know them), and the only
bridge is inside NegotiatorImpl. I don't know if there's a better way
to do this. The HttpClient class seems having similar info but
sometimes it's null and I don't know why. Sorry if I reinvent a wheel-
cart to carry these info.
Thanks
Max
This is not a problem just a question to see if I understand
correctly the changes.

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
