| 2021-03-03 | Bluetooth: btqcomsmd: Fix a resource leak in error handling paths in the ↵ |   Christophe JAILLET | |
| probe function [ Upstream commit 9a39a927be01d89e53f04304ab99a8761e08910d ] Some resource should be released in the error handling path of the probe function, as already done in the remove function. The remove function was fixed in commit 5052de8deff5 ("soc: qcom: smd: Transition client drivers from smd to rpmsg") Fixes: 1511cc750c3d ("Bluetooth: Introduce Qualcomm WCNSS SMD based HCI driver") Signed-off-by: Christophe JAILLET <christophe.jaillet@wanadoo.fr> Signed-off-by: Marcel Holtmann <marcel@holtmann.org> Signed-off-by: Sasha Levin <sashal@kernel.org> | |||
| 2018-03-24 | Bluetooth: btqcomsmd: Fix skb double free corruption |   Loic Poulain | |
| [ Upstream commit 67b8fbead4685b36d290a0ef91c6ddffc4920ec9 ] In case of hci send frame failure, skb is still owned by the caller (hci_core) and then should not be freed. This fixes crash on dragonboard-410c when sending SCO packet. skb is freed by both btqcomsmd and hci_core.

| 2017-11-30 | Bluetooth: btqcomsmd: Add support for BD address setup | Loic Poulain | |
| commit 6e518111060c2290427d79c43d4add9600ad852b upstream. This patch implements the hdev setup function since wcnss-bt does not have persistent memory to store an allocated BD address. The device is therefore marked as unconfigured if no BD address has been previously retrieved.

| 2017-06-16 | networking: introduce and use skb_put_data() |   Johannes Berg | |
| A common pattern with skb_put() is to just want to memcpy() some data into the new space, introduce skb_put_data() for this. An spatch similar to the one for skb_put_zero() converts many of the places using it: @@ identifier p, p2; expression len, skb, data; type t, t2; @@ ( -p = skb_put(skb, len); +p = skb_put_data(skb, data, len); | -p = (t)skb_put(skb, len); +p = skb_put_data(skb, data, len); ) ( p2 = (t2)p; -memcpy(p2, data, len); | -memcpy(p, data, len); ) @@ type t, t2; identifier p, p2; expression skb, data; @@ t *p; ... ( -p = skb_put(skb, sizeof(t)); +p = skb_put_data(skb, data, sizeof(t)); | -p = (t *)skb_put(skb, sizeof(t)); +p = skb_put_data(skb, data, sizeof(t)); ) ( p2 = (t2)p; -memcpy(p2, data, sizeof(*p)); | -memcpy(p, data, sizeof(*p)); ) @@ expression skb, len, data; @@ -memcpy(skb_put(skb, len), data, len); +skb_put_data(skb, data, len); (again, manually post-processed to retain some comments) Reviewed-by: Stephen Hemminger <stephen@networkplumber.org> Signed-off-by: Johannes Berg <johannes.berg@intel.com> Signed-off-by: David S.

| 2017-03-28 | soc: qcom: smd: Transition client drivers from smd to rpmsg |   Bjorn Andersson | |
| By moving these client drivers to use RPMSG instead of the direct SMD API we can reuse them ontop of the newly added GLINK wire-protocol support found in the 820 and 835 Qualcomm platforms. As the new (RPMSG-based) and old SMD implementations are mutually exclusive we have to change all client drivers in one commit, to make sure we have a working system before and after this transition.

| 2017-02-16 | Bluetooth: btqcomsmd: Fix module autoload |   Javier Martinez Canillas | |
| If the driver is built as a module, autoload won't work because the module alias information is not filled. So user-space can't match the registered device with the corresponding module. Export the module alias information using the MODULE_DEVICE_TABLE() macro. Before this patch: $ modinfo drivers/bluetooth/btqcomsmd.ko | grep alias $ After this patch: $ modinfo drivers/bluetooth/btqcomsmd.ko | grep alias alias: of:N*T*Cqcom,wcnss-btC* alias: of:N*T*Cqcom,wcnss-bt Signed-off-by: Javier Martinez Canillas <javier@osg.samsung.com> Signed-off-by: Marcel Holtmann <marcel@holtmann.org> | |||
| 2016-09-19 | Bluetooth: Introduce Qualcomm WCNSS SMD based HCI driver |   Bjorn Andersson | |
| The Qualcomm WCNSS chip provides two SMD channels to the BT core; one for command and one for event packets. This driver exposes the two channels as a hci device.
