* Rationalized the key wrapping format. It currently is:Nikos Mavrogiannopoulos2010-09-051-18/+144
| | | | | | | | | | | PackedData ::= SEQUENCE { version INTEGER { v1(0) } algorithm OBJECT IDENTIFIER, type INTEGER { secret_key(0), public(1), private(2) }, data OCTET STRING } Unfortunately there are not assigned OIDs for all algorithms we support.

| | | | | | | | | | | | | | | Document how members of session_item_st are protected, and what assumptions are made by internal functions.
* | | Move session_item_st definition to ncr-sessions.cMiloslav Trmač2010-08-251-0/+26
| | | | | | | | | | | | It is not used anywhere else.
* | | Unpublish session ID at start of ncr_session_final.Miloslav Trmač2010-08-251-21/+28
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This means that ncr_session_final() can't be called on one ID twice, ensuring that the ID is still unique throughout the runtime of ncr_session_final(). (Note that this is not guaranteed for ncr_session_update(): a concurrent thread can call ncr_session_final() on the ID and reuse it before ncr_session_update() finishes.)
* | | Rename ncr_sessions_item_get() to session_get_ref()Miloslav Trmač2010-08-251-4/+4
| | | | | | | | | | | | ... for consistency with the other session ID handlers.

| | | | | | | | | | | | | | | Also skip locking the mutex - the session is private to the calling thread, nothing else can access it.

|/ | | | | | | | | | | | | | Should result in no functionality change. This makes the code marginally more effective (reducing the number of "&lst->key" and "&lst->sessions" operations in the code, and moving them toward dereferences where they can be combined with member accesses), and more type-safe (prevents mixing the key and session list in most places because they the difference is only in the low-level accessor functions). Most importantly, this allows replacing list_sem_st without having to touch most of the functions again.
