crypto: testmgr - Dynamically allocate xbuf and axbuf
We currently allocate temporary memory that is used for testing statically. This renders the testing engine non-reentrant. As algorithms may nest, i.e., one may construct another in order to carry out a part of its operation, this is unacceptable. For example, it has been reported that an AEAD implementation allocates a cipher in its setkey function, which causes it to fail during testing as the temporary memory is overwritten. This patch replaces the static memory with dynamically allocated buffers. We need a maximum of 16 pages so this slightly increases the chances of an algorithm failing due to memory shortage. However, as testing usually occurs at registration, this shouldn't be a big problem. Reported-by: Shasi Pulijala <spulijala@amcc.com> Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
