Subject: crypto: aesni - Fix out-of-bounds access of the AAD buffer in generic-gcm-aesni
From: Junaid Shahid <junaids(a)google.com>
commit 1ecdd37e308ca149dc378cce225068cbac54e3a6 upstream.
The aesni_gcm_enc/dec functions can access memory after the end of
the AAD buffer if the AAD length is not a multiple of 4 bytes.
It didn't matter with rfc4106-gcm-aesni as in that case the AAD was
always followed by the 8 byte IV, but that is no longer the case with
generic-gcm-aesni. This can potentially result in accessing a page that
is not mapped and thus causing the machine to crash. This patch fixes
that by reading the last <16 byte block of the AAD byte-by-byte and
optionally via an 8-byte load if the block was at least 8 bytes.
Fixes: 0487ccac ("crypto: aesni - make non-AVX AES-GCM work with any aadlen")

Subject: ALSA: hda - Reduce the suspend time consumption for ALC256
From: Takashi Iwai <tiwai(a)suse.de>
commit 1c9609e3a8cf5997bd35205cfda1ff2218ee793b upstream.
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.

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.

Subject: power: reset: zx-reboot: add missing MODULE_DESCRIPTION/AUTHOR/LICENSE
From: Jesse Chan <jc(a)linux.com>
commit 348c7cf5fcbcb68838255759d4cb45d039af36d2 upstream.
This change resolves a new compile-time warning
when built as a loadable module:
WARNING: modpost: missing MODULE_LICENSE() in drivers/power/reset/zx-reboot.o
see include/linux/module.h for more information
This adds the license as "GPL v2", which matches the header of the file.
MODULE_DESCRIPTION and MODULE_AUTHOR are also added.

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.
