* Fix for bug 1038302 - corbin |
|
1541 |
* There is a problem here if anonymous access is |
|
1542 |
* disallowed. If the current request is part of the |
|
1543 |
* client's mount process for the requested filesystem, |
|
1544 |
* then it will carry root (uid 0) credentials on it, and |
|
1545 |
* will be denied by checkauth if that client does not |
|
1546 |
* have explicit root=0 permission. This will cause the |
|
1547 |
* client's mount operation to fail. As a work-around, |
|
1548 |
* we check here to see if the request is a getattr or |
|
1549 |
* statfs operation on the exported vnode itself, and |
|
1550 |
* pass a flag to checkauth with the result of this test. |
|
1551 |
* |
|
1552 |
* The filehandle refers to the mountpoint itself if |
|
1553 |
* the fh_data and fh_xdata portions of the filehandle |
|
1554 |
* are equal. |
|
1555 |
* |
