Fix 2009/05/19 |

|
@ Don't call get_fs_type() with a mutex held. |
| 1966 |
|
|
| 1967 |
|
Until now, when ccs_update_mount_acl() is called with unsupported |
| 1968 |
|
filesystem, /sbin/modprobe is executed from get_fs_type() to load |
| 1969 |
|
filesystem module. And get_fs_type() does not return until /sbin/modprobe |
| 1970 |
|
finishes. |
| 1971 |
|
|
| 1972 |
|
This means that it will cause deadlock if /sbin/modprobe (which is |
| 1973 |
|
executed via get_fs_type() in ccs_update_mount_acl()) calls |
| 1974 |
|
ccs_update_mount_acl(); although it won't happen unless an administrator |
| 1975 |
|
inserts execute_handler to call mount() requests in learning mode or to |
| 1976 |
|
add "allow_mount" entries to /proc/ccs/system_policy . |
| 1977 |
|
|
| 1978 |
|
I modified to unlock the mutex before calling get_fs_type(). |
