  "message": "CRED: Add some configurable debugging [try #6]\n\nAdd a config option (CONFIG_DEBUG_CREDENTIALS) to turn on some debug checking\nfor credential management.  The additional code keeps track of the number of\npointers from task_structs to any given cred struct, and checks to see that\nthis number never exceeds the usage count of the cred struct (which includes\nall references, not just those from task_structs).\n\nFurthermore, if SELinux is enabled, the code also checks that the security\npointer in the cred struct is never seen to be invalid.\n\nThis attempts to catch the bug whereby inode_has_perm() faults in an nfsd\nkernel thread on seeing cred-\u003esecurity be a NULL pointer (it appears that the\ncredential struct has been previously released):\n\n\thttp://www.kerneloops.org/oops.php?number\u003d252883\n\nSigned-off-by: David Howells \u003cdhowells@redhat.com\u003e\nSigned-off-by: James Morris \u003cjmorris@namei.org\u003e\n",
