Jeff Roberson	8f70816cf2	Hide a pointer to the malloc_type bucket at the end of the freed memory. If ... this memory is modified after it has been freed we can now report it's previous owner.	2002-05-02 09:07:04 +00:00
Jeff Roberson	639c9550fb	Remove the temporary alignment check in free(). ... Implement the following checks on freed memory in the bucket path: - Slab membership - Alignment - Duplicate free This previously was only done if we skipped the buckets. This code will slow down INVARIANTS a bit, but it is smp safe. The checks were moved out of the normal path and into hooks supplied in uma_dbg.	2002-05-02 02:08:48 +00:00
Jeff Roberson	8efc4eff00	Add a new UMA debugging facility. This will overwrite freed memory with ... 0xdeadc0de and then check for it just before memory is handed off as part of a new request. This will catch any post free/pre alloc modification of memory, as well as introduce errors for anything that tries to dereference it as a pointer. This code takes the form of special init, fini, ctor and dtor routines that are specificly used by malloc. It is in a seperate file because additional debugging aids will want to live here as well.	2002-04-30 07:54:25 +00:00
