| 35 | <para>cifs.upcall is a userspace helper program for the linux CIFS client
|
|---|
| 36 | filesystem. There are a number of activities that the kernel cannot easily
|
|---|
| 37 | do itself. This program is a callout program that does these things for the
|
|---|
| 38 | kernel and then returns the result.</para>
|
|---|
| 39 |
|
|---|
| 40 | <para>cifs.upcall is generally intended to be run when the kernel calls
|
|---|
| 41 | request-key<manvolnum>8</manvolnum> for a particular key type. While it
|
|---|
| 42 | can be run directly from the command-line, it's not generally intended
|
|---|
| 43 | to be run that way.</para>

|

| 65 | <para>cifs.upcall is designed to be called from the kernel via the
|
|---|
| 66 | request-key callout program. This requires that request-key be told
|
|---|
| 67 | where and how to call this program. The current cifs.upcall program
|
|---|
| 68 | handles two different key types:
