This series of patches provides a pioctl() system call, and makes kAFS use it
to provide a number of of the OpenAFS pioctl functions sufficient to allow a
number of OpenAFS userspace utilities work with kAFS.
File-requiring pioctls have been tested with:
[root at andromeda ~]# fs getfid /afs
File /afs (1.1.0) contained in volume 1
[root at andromeda ~]# fs whichcell /afs
File /afs lives in cell 'procyon.org.uk'
[root at andromeda ~]# fs examine /afs
fs: You don't have the required access rights on '/afs'
[root at andromeda ~]# fs whereis /afs
File /afs is on host altair.procyon.org.uk
Non-file-requiring pioctls for manipulating authentication tokens have been
tested with:
[root at andromeda ~]# kinit admin/admin
Password for admin/admin at PROCYON.ORG.UK:
[root at andromeda ~]# klog admin
Password:
[root at andromeda ~]# keyctl show
Session Keyring
-3 --alswrv 0 0 keyring: _ses
939040040 --als--v 0 0 \_ rxrpc: afs at PROCYON.ORG.UK
[root at andromeda ~]# fs examine /afs
File /afs (1.1.32558) contained in volume 1
Volume status for vid = 536870912 named
Current disk quota is 5000
Current blocks used are 2
The partition has 39007484 blocks available out of 39187776
[root at andromeda ~]# aklog
[root at andromeda ~]# keyctl show
Session Keyring
-3 --alswrv 0 0 keyring: _ses
660792724 --als--v 0 0 \_ rxrpc: afs at PROCYON.ORG.UK
[root at andromeda ~]# tokens
Tokens held by the Cache Manager:
User's (AFS ID 10143) tokens for afs at PROCYON.ORG.UK [Expires Jun 17 00:47]
--End of list--
The AFS keys probably should be in their own keyring which is linked to from
the session keyring.
