This patch fixes a host of reentrancy bugs in the nx driver. The following algorithms are affected: * CCM * GCM * CTR * XCBC * SHA256 * SHA512 The crypto API allows a single transform to be used by multiple threads simultaneously. For example, IPsec will use a single tfm to process packets for a given SA. As packets may arrive on multiple CPUs that tfm must be reentrant. The nx driver does try to deal with this by using a spin lock. Unfortunately only the basic AES/CBC/ECB algorithms do this in the correct way. The symptom of these bugs may range from the generation of incorrect output to memory corruption. Cc: stable@vger.kernel.org Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au> |
