    crypto: algapi - reject NULL crypto_spawn::inst · 6b476662
    Eric Biggers authored
    It took me a while to notice the bug where the adiantum template left
    crypto_spawn::inst == NULL, because this only caused problems in certain
    cases where algorithms are dynamically loaded/unloaded.
    
    More improvements are needed, but for now make crypto_init_spawn()
    reject this case and WARN(), so this type of bug will be noticed
    immediately in the future.
    
    Note: I checked all callers and the adiantum template was the only place
    that had this wrong.  So this WARN shouldn't trigger anymore.
