82 | /* Historically, the keys in _PATH_MP_DB/_PATH_SMP_DB had the format |
83 | * `1 octet tag | key', where the tag is one of the _PW_KEY* values | |
84 | * listed below. These values happen to be ASCII digits. | |
85 | * The tag is now still a single octet, but the | |
86 | * upper 4 bits are interpreted as a version. Previous format | |
87 | * entries are version `3' -- this conveniently results in the same | |
88 | * key values as before. The new, architecture-independent entries | |
89 | * are version `4'. | |
90 | * As it happens, some applications read the database directly. | |
91 | * (Bad app, no cookie!) Thus, we leave the _PW_KEY* symbols at their | |
92 | * old values so these apps still work. Consequently | |
93 | * we have to muck around a bit more to get the correct, versioned | |
94 | * tag, and that is what the _PW_VERSIONED macro is about. | |
