# The way kmem_cache aliasing is done in the kernel is broken.

# The problem with kmem_cache* is this:
|
|
# *) Assume CONFIG_SLUB is set
|
|
# 1) kmem_cache_create(name="foo-a")
|
|
# - creates new kmem_cache structure
|
|
# 2) kmem_cache_create(name="foo-b")
|
|
# - If identical cache characteristics, it will be merged with the previously
|
|
# created cache associated with "foo-a". The cache's refcount will be
|
|
# incremented and an alias will be created via sysfs_slab_alias().
|
|
# 3) kmem_cache_destroy(<ptr>)
|
|
# - Attempting to destroy cache associated with "foo-a", but instead the
|
|
# refcount is simply decremented. I don't even think the sysfs aliases are
|
|
# ever removed...
|
|
# 4) kmem_cache_create(name="foo-a")
|
|
# - This FAILS because kmem_cache_sanity_check colides with the existing
|
|
# name ("foo-a") associated with the non-removed cache.
|
|
#
|
|
# This is a problem for RAID (specifically dm-raid) because the name used
|
|
# for the kmem_cache_create is ("raid%d-%p", level, mddev). If the cache
|
|
# persists for long enough, the memory address of an old mddev will be
|
|
# reused for a new mddev - causing an identical formulation of the cache
|
|
# name. Even though kmem_cache_destory had long ago been used to delete
|
|
# the old cache, the merging of caches has cause the name and cache of that
|
|
# old instance to be preserved and causes a colision (and thus failure) in
|
|
# kmem_cache_create(). I see this regularly in testing the following
|
|
# kernels:
