+Subject: ALSA: hda - Reduce the suspend time consumption for ALC256
+
+From: Takashi Iwai <tiwai@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.
+
+Fixes: 4a219ef8f370 ("ALSA: hda/realtek - Add ALC256 HP depop function")

+Subject: crypto: aesni - add wrapper for generic gcm(aes)
+
+From: Sabrina Dubroca <sd@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.

+Subject: crypto: aesni - Fix out-of-bounds access of the AAD buffer in generic-gcm-aesni
+
+From: Junaid Shahid <junaids@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.

+Subject: crypto: aesni - Fix out-of-bounds access of the data buffer in generic-gcm-aesni
+
+From: Junaid Shahid <junaids@google.com>
+
+commit b20209c91e23a9bbad9cac2f80bc16b3c259e10e upstream.
+
+The aesni_gcm_enc/dec functions can access memory before the start of
+the data buffer if the length of the data buffer is less than 16 bytes.
+This is because they perform the read via a single 16-byte load. 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
+partial block byte-by-byte and optionally an via 8-byte load if the block
+was at least 8 bytes.

+
+commit 106840c41096a01079d3a2025225029c13713802 upstream.
+
+generic_gcmaes_decrypt needs to use generic_gcmaes_ctx, not
+aesni_rfc4106_gcm_ctx. This is actually harmless because the fields in
+struct generic_gcmaes_ctx share the layout of the same fields in
+aesni_rfc4106_gcm_ctx.

+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.

+
+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.

+From: Antoine Tenart <antoine.tenart@free-electrons.com>
+
+commit c957f8b3e2e54b29f53ef69decc87bbc858c9b58 upstream.
+
+This patch adds a parameter in the SafeXcel ahash request structure to
+keep track of the number of SG entries mapped. This allows not to call
+dma_unmap_sg() when dma_map_sg() wasn't called in the first place. This
+also removes a warning when the debugging of the DMA-API is enabled in
+the kernel configuration: "DMA-API: device driver tries to free DMA
+memory it has not allocated".

+
+commit 809778e02cd45d0625439fee67688f655627bb3c upstream.
+
+This patch fixes the hash support in the SafeXcel driver when the update
+size is a multiple of a block size, and when a final call is made just
+after with a size of 0. In such cases the driver should cache the last
+block from the update to avoid handling 0 length data on the final call
+(that's a hardware limitation).

+Subject: HID: wacom: EKR: ensure devres groups at higher indexes are released
+
+From: Aaron Armstrong Skomra <skomra@gmail.com>
+
+commit 791ae273731fa85d3332e45064dab177ae663e80 upstream.
+
+Background: ExpressKey Remotes communicate their events via usb dongle.
+Each dongle can hold up to 5 pairings at one time and one EKR (identified
+by its serial number) can unfortunately be paired with its dongle
+more than once. The pairing takes place in a round-robin fashion.
+
+Input devices are only created once per EKR, when a new serial number
+is seen in the list of pairings. However, if a device is created for
+a "higher" paring index and subsequently a second pairing occurs at a
+lower pairing index, unpairing the remote with that serial number from
+any pairing index will currently cause a driver crash. This occurs
+infrequently, as two remotes are necessary to trigger this bug and most
+users have only one remote.
+
+As an illustration, to trigger the bug you need to have two remotes,
+and pair them in this order:
+
+1. slot 0 -> remote 1 (input device created for remote 1)
+2. slot 1 -> remote 1 (duplicate pairing - no device created)
+3. slot 2 -> remote 1 (duplicate pairing - no device created)
+4. slot 3 -> remote 1 (duplicate pairing - no device created)
+5. slot 4 -> remote 2 (input device created for remote 2)
+
+6. slot 0 -> remote 2 (1 destroyed and recreated at slot 1)
+7. slot 1 -> remote 2 (1 destroyed and recreated at slot 2)
+8. slot 2 -> remote 2 (1 destroyed and recreated at slot 3)
+9. slot 3 -> remote 2 (1 destroyed and not recreated)
+10. slot 4 -> remote 2 (2 was already in this slot so no changes)
+
+11. slot 0 -> remote 1 (The current code sees remote 2 was paired over in
+ one of the dongle slots it occupied and attempts
+ to remove all information about remote 2 [1]. It
+ calls wacom_remote_destroy_one for remote 2, but
+ the destroy function assumes the lowest index is
+ where the remote's input device was created. The
+ code "cleans up" the other remote 2 pairings
+ including the one which the input device was based
+ on, assuming they were were just duplicate
+ pairings. However, the cleanup doesn't call the
+ devres release function for the input device that
+ was created in slot 4).
+
+This issue is fixed by this commit.
+
+[1] Remote 2 should subsequently be re-created on the next packet from the
+EKR at the lowest numbered slot that it occupies (here slot 1).

+Subject: HID: wacom: Fix reporting of touch toggle (WACOM_HID_WD_MUTE_DEVICE) events
+
+From: Jason Gerecke <killertofu@gmail.com>
+
+commit 403c0f681c1964ff1db8c2fb8de8c4067779d081 upstream.
+
+Touch toggle softkeys send a '1' while pressed and a '0' while released,
+requring the kernel to keep track of wether touch should be enabled or
+disabled. The code does not handle the state transitions properly,
+however. If the key is pressed repeatedly, the following four states
+of states are cycled through (assuming touch starts out enabled):
+
+Press: shared->is_touch_on => 0, SW_MUTE_DEVICE => 1
+Release: shared->is_touch_on => 0, SW_MUTE_DEVICE => 1
+Press: shared->is_touch_on => 1, SW_MUTE_DEVICE => 0
+Release: shared->is_touch_on => 1, SW_MUTE_DEVICE => 1
+
+The hardware always properly enables/disables touch when the key is
+pressed but applications that listen for SW_MUTE_DEVICE events to provide
+feedback about the state will only ever show touch as being enabled while
+the key is held, and only every-other time. This sequence occurs because
+the fallthrough WACOM_HID_WD_TOUCHONOFF case is always handled, and it
+uses the value of the *local* is_touch_on variable as the value to
+report to userspace. The local value is equal to the shared value when
+the button is pressed, but equal to zero when the button is released.
+
+Reporting the shared value to userspace fixes this problem, but the
+fallthrough case needs to update the shared value in an incompatible
+way (which is why the local variable was introduced in the first place).
+To work around this, we just handle both cases in a single block of code
+and update the shared variable as appropriate.

+
+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.

+
+commit 36447456e1cca853188505f2a964dbbeacfc7a7a upstream.
+
+The switch to uuid_t invereted the logic of verfication that &entry->fsuuid
+is zero during parsing of "fsuuid=" rule. Instead of making sure the
+&entry->fsuuid field is not attempted to be overwritten, we bail out for
+perfectly correct rule.

+Subject: scsi: aacraid: Fix hang in kdump
+
+From: Raghava Aditya Renukunta <RaghavaAditya.Renukunta@microsemi.com>
+
+commit c5313ae8e4e037bfaf5e56cb8d6efdb8e92ce437 upstream.
+
+Driver attempts to perform a device scan and device add after coming out
+of reset. At times when the kdump kernel loads and it tries to perform
+eh recovery, the device scan hangs since its commands are blocked because
+of the eh recovery. This should have shown up in normal eh recovery path
+(Should have been obvious)
+
+Remove the code that performs scanning.I can live without the rescanning
+support in the stable kernels but a hanging kdump/eh recovery needs to be
+fixed.

+
+commit 1696784eb7b52b13b62d160c028ef2c2c981d4f2 upstream.
+
+The GPIO tools build fails when using a buildroot toolchain that uses musl
+as it's C library:
+
+arm-broomstick-linux-musleabi-gcc -Wp,-MD,./.gpio-event-mon.o.d \
+ -Wp,-MT,gpio-event-mon.o -O2 -Wall -g -D_GNU_SOURCE \
+ -Iinclude -D"BUILD_STR(s)=#s" -c -o gpio-event-mon.o gpio-event-mon.c
+gpio-event-mon.c:30:6: error: unknown type name ‘u_int32_t’; did you mean ‘uint32_t’?
+ u_int32_t handleflags,
+ ^~~~~~~~~
+ uint32_t
+
+The glibc headers installed on my laptop include sys/types.h in
+unistd.h, but it appears that musl does not.
