mac80211: move struct aead_req off the stack Some crypto implementations (such as the generic CCM wrapper in crypto/) use scatterlists to map fields of private data in their struct aead_req. This means these data structures cannot live in the vmalloc area, which means that they cannot live on the stack (with CONFIG_VMAP_STACK.) This currently occurs only with the generic software implementation, but the private data and usage is implementation specific, so move the whole data structures off the stack into heap by allocating every time we need to use them. In addition, take care not to put any of our own stack allocations into scatterlists. This involves reserving some extra room when allocating the aead_request structures, and referring to those allocations in the scatter- lists (while copying the data from the stack before the crypto operation) Signed-off-by: Ard Biesheuvel <ard.biesheuvel@linaro.org> Signed-off-by: Johannes Berg <johannes.berg@intel.com> 2016-10-17 14:05:33 +00:00			`#define GMAC_AAD_LEN 20`
