Chen Gang	4380be0e99	migration: Plug memory leak in migrate-set-cache-size command We call g_free() after cache_fini() in migration_end(), but we don't call it after cache_fini() in xbzrle_cache_resize(), leaking the memory. cache_init() and cache_fini() are a pair. Since cache_init() allocates the cache, let cache_fini() free it. This plugs the leak.

Dr. David Alan Gilbert	6d3cb1f970	Fix two XBZRLE corruption issues Push zero'd pages into the XBZRLE cache A page that was cached by XBZRLE, zero'd and then XBZRLE'd again was being compared against a stale cache value Don't use 'qemu_put_buffer_async' to put pages from the XBZRLE cache Since the cache might change before the data hits the wire Signed-off-by: Dr. David Alan Gilbert <dgilbert@redhat.com> Signed-off-by: Juan Quintela <quintela@redhat.com>	13 years ago

Peter Lieven	ee0b44aa9d	page_cache: dup memory on insert The page cache frees all data on finish, on resize and if there is collision on insert. So it should be the caches responsibility to dup the data that is stored in the cache.

Peter Lieven	32a1c08b60	page_cache: fix memory leak XBZRLE encoded migration introduced a MRU page cache meachnism. Unfortunately, cached items where never freed in case of a collision in the page cache on cache_insert(). This lead to out of memory conditions during XBZRLE migration if the page cache was small and there where a lot of collisions in the cache.
