Subject: [Bug nscd/5381] New: nscd: Race condition of mempool_alloc() .. cache_add() and gc()
Date: Wed, 21 Nov 2007 04:58:00 -0000 [thread overview]
Message-ID: <20071121045836.5381.pasky@suse.cz> (raw)
nscd does not use sufficient locking, allowing gc() to be run between
mempool_alloc() of data and its addition by cache_add(). Thus, gc() will free
the data again before it could have been added and properly accounted for. The
code should take the read database lock already before the mempool_alloc() call.
