The bug halt occured because the page\nthat I passed to kfree failed the PageCompound and PageSlab test in the slub\nimplementation of kfree. I tracked the problem down to the following set of\nevents:\n\n1) dccp, unlike all other uses of kmem_cache_create, allocates a string\ndynamically when registering a slab cache. This allocated string is freed when\nthe cache is destroyed.\n\n2) Normally, (1) is not an issue, but when Slub is in use, it is possible that\ncaches are \u0027merged\u0027. This process causes multiple caches of simmilar\nconfiguration to use the same cache data structure. When this happens, the new\nname of the cache is effectively dropped.\n\n3) (2) results in kmem_cache_name returning an ambigous value (i.e.\nccid_kmem_cache_destroy, which uses this fuction to retrieve the name pointer\nfor freeing), is no longer guaranteed that the string it assigned is what is\nreturned.\n\n4) If such merge event occurs, ccid_kmem_cache_destroy frees the wrong pointer,\nwhich trips over the BUG in the slub implementation of kfree (since its likely\nnot a slab allocation, but rather a pointer into the static string table\nsection.\n\nSo, what to do about this. At first blush this is pretty clearly a leak in the\ninformation that slub owns, and as such a slub bug. Unfortunately, theres no\nreally good way to fix it, without exposing slub specific implementation details\nto the generic slab interface. Also, even if we could fix this in slub cleanly,\nI think the RCU free option would force us to do lots of string duplication, not\nonly in slub, but in every slab allocator. As such, I\u0027d like to propose this\nsolution. Basically, I just move the storage for the kmem cache name to the\nccid_operations structure. In so doing, we don\u0027t have to do the kstrdup or\nkfree when we allocate/free the various caches for dccp, and so we avoid the\nproblem, by storing names with static memory, rather than heap, the way all\nother calls to kmem_cache_create do.\n\nI\u0027ve tested this out myself here, and it solves the problem quite well.\n\nSigned-off-by: Neil Horman \u003cnhorman@tuxdriver.com\u003e\nAcked-by: Arnaldo Carvalho de Melo \u003cacme@redhat.com\u003e\nSigned-off-by: David S.
