netfilter: fix double-free and use-after free

2008-07-27T00:49:33+00:00

As suggested by Patrick McHardy, introduce a __krealloc() that doesn't free the original buffer to fix a double-free and use-after-free bug introduced by me in netfilter that uses RCU.

SL*B: drop kmem cache argument from constructor

2008-07-26T19:00:07+00:00

Kmem cache passed to constructor is only needed for constructors that are themselves multiplexeres. Nobody uses this "feature", nor does anybody uses passed kmem cache in non-trivial way, so pass only pointer to object. Non-trivial places are: arch/powerpc/mm/init_64.c arch/powerpc/mm/hugetlbpage.c This is flag day, yes.

kcalloc: remove runtime division

2008-07-24T17:47:21+00:00

While in all cases in the kernel we know the size of the elements to be created, we don't always know the count of elements. By commuting the size and count in the overflow check, the compiler can reduce the runtime division of size_t with a compare to a (unique) constant in these cases.

Christoph has moved

2008-07-04T17:40:04+00:00

Remove all clameter@sgi.com addresses from the kernel tree since they will become invalid on June 27th. Change my maintainer email address for the slab allocators to cl@linux-foundation.org (which will be the new email address for the future).

slab: add a flag to prevent debug_free checks on a kmem_cache

2008-04-30T15:29:53+00:00

This is a preperatory patch for the debugobjects infrastructure. The flag prevents debug_free checks on kmem_caches. This is necessary to avoid resursive calls into a debug mechanism which uses a kmem_cache itself.
