44 | * This is the repository for labels seen so that it is | |
45 | * not necessary to keep allocating tiny chuncks of memory | |
46 | * and so that they can be shared. | |
47 | * | |
48 | * Labels are never modified in place. Anytime a label | |
49 | * is imported (e.g. xattrset on a file) the list is checked | |
50 | * for it and it is added if it doesn't exist. The address | |
51 | * is passed out in either case. Entries are added, but | |
52 | * never deleted. | |
53 | * | |
54 | * Since labels are hanging around anyway it doesn't | |
55 | * hurt to maintain a secid for those awkward situations | |
56 | * where kernel components that ought to use LSM independent | |
57 | * interfaces don't. The secid should go away when all of | |
58 | * these components have been repaired. | |
59 | * | |
60 | * The cipso value associated with the label gets stored here, too. | |
61 | * | |
62 | * Keep the access rules for this subject label here so that | |
63 | * the entire set of rules does not need to be examined every | |
64 | * time. | |
