This is a note to let you know that I've just added the patch titled crypto: aesni - add wrapper for generic gcm(aes) to the 4.14-stable tree which can be found at: http://www.kernel.org/git/?p=linux/kernel/git/stable/stable-queue.git;a=sum… The filename of the patch is: crypto-aesni-add-wrapper-for-generic-gcm-aes.patch and it can be found in the queue-4.14 subdirectory. If you, or anyone else, feels it should not be added to the stable tree, please let <stable(a)vger.kernel.org> know about it. >From fc8517bf627c9b834f80274a1bc9ecd39b27231b Mon Sep 17 00:00:00 2001 From: Sabrina Dubroca <sd(a)queasysnail.net> Date: Wed, 13 Dec 2017 14:54:36 +0100 Subject: crypto: aesni - add wrapper for generic gcm(aes) From: Sabrina Dubroca <sd(a)queasysnail.net> commit fc8517bf627c9b834f80274a1bc9ecd39b27231b upstream. When I added generic-gcm-aes I didn't add a wrapper like the one provided for rfc4106(gcm(aes)). We need to add a cryptd wrapper to fall back on in case the FPU is not available, otherwise we might corrupt the FPU state.

ALC256 has its own quirk to override the shutup call, and it contains the COEF update for pulling down the headset jack control. Currently, the COEF update is called after clearing the headphone pin, and this seems triggering a stall of the codec communication, and results in a long delay over a second at suspend. A quick resolution is to swap the calls: at first with the COEF update, then clear the headphone pin.

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.

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.

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.
