+Subject: crypto: aesni - handle zero length dst buffer
+
+From: Stephan Mueller <smueller@chronox.de>
+
+commit 9c674e1e2f9e24fa4392167efe343749008338e0 upstream.
+
+GCM can be invoked with a zero destination buffer. This is possible if
+the AAD and the ciphertext have zero lengths and only the tag exists in
+the source buffer (i.e. a source buffer cannot be zero). In this case,
+the GCM cipher only performs the authentication and no decryption
+operation.
+
+When the destination buffer has zero length, it is possible that no page
+is mapped to the SG pointing to the destination. In this case,
+sg_page(req->dst) is an invalid access. Therefore, page accesses should
+only be allowed if the req->dst->length is non-zero which is the
+indicator that a page must exist.
+
+This fixes a crash that can be triggered by user space via AF_ALG.

+Subject: crypto: af_alg - whitelist mask and type
+
+From: Stephan Mueller <smueller@chronox.de>
+
+commit bb30b8848c85e18ca7e371d0a869e94b3e383bdf upstream.
+
+The user space interface allows specifying the type and mask field used
+to allocate the cipher. Only a subset of the possible flags are intended
+for user space. Therefore, white-list the allowed flags.
+
+In case the user space caller uses at least one non-allowed flag, EINVAL
+is returned.

+
+As it turns out, normally the freeing of IRQs that would fix this is called
+inside of the scope of __igb_close(). However, since the device is
+already gone by the point we try to unregister the netdevice from the
+driver due to a hotplug we end up seeing that the netif isn't present
+and thus, forget to free any of the device IRQs.
+
+So: make sure that if we're in the process of dismantling the netdev, we
+always allow __igb_close() to be called so that IRQs may be freed
+normally. Additionally, only allow igb_close() to be called from
+__igb_close() if it hasn't already been called for the given adapter.
