[ Upstream commit ce32c0a5 ] Existing code returns the max of the decoded size and buffer size. It turns out that buffer size is always greater due to hardware alignment requirement. As a result, payload size given to client is incorrect. This change ensures that the bytesused is assigned to actual payload size, when available. Signed-off-by:

[ Upstream commit 32ae5920 ] Shifting the u8 value[3] by an int can lead to sign-extension overflow. For example, if value[3] is 0xff and the shift is 24 then it is promoted to int and then the top bit is sign-extended so that all upper 32 bits are set. Fix this by casting value[3] to a u32 before the shift. Detected by CoverityScan, CID#1016522 ("Unintended sign extension") Fixes: e0d3bafd ("V4L/DVB (10954): Add cx231xx USB driver") Signed-off-by:

[ Upstream commit 1eb8d738 ] Flushing the workqueue can cause operations to happen which might call gfs2_log_reserve(), or get stuck waiting for locks taken by such operations. gfs2_log_reserve() can io_schedule(). If this happens, it will never wake because the only thing which can wake it is gfs2_logd() which was already stopped. This causes umount of a gfs2 filesystem to wedge permanently if, for example, the umount immediately follows a large delete operation.

[ Upstream commit a26ac6c1 ] In isif_probe(), there is a while loop to get the ISIF base address and linearization table0 and table1 address. In the loop body, the function platform_get_resource() is called to get the resource. If platform_get_resource() returns NULL, the loop is terminated and the execution goes to 'fail_nobase_res'. Suppose the loop is terminated at the first iteration because platform_get_resource() returns NULL and the execution goes to 'fail_nobase_res'. Given that there is another while loop at 'fail_nobase_res' and i equals to 0, one iteration of the second while loop will be executed. However, the second while loop does not check the return value of platform_get_resource(). This can cause a NULL pointer dereference bug if the return value is a NULL pointer. This patch avoids the above issue by adding a check in the second while loop after the call to platform_get_resource(). Signed-off-by:

[ Upstream commit e5f3530c ] The CBM overlap test is used to manage the allocations of RDT resources where overlap is possible between resource groups. When a resource group is in exclusive mode then there should be no overlap between resource groups. The current overlap test only considers overlap between the same resources, for example, that usage of a RDT_RESOURCE_L2DATA resource in one resource group does not overlap with usage of a RDT_RESOURCE_L2DATA resource in another resource group. The problem with this is that it allows overlap between a RDT_RESOURCE_L2DATA resource in one resource group with a RDT_RESOURCE_L2CODE resource in another resource group - even if both resource groups are in exclusive mode. This is a problem because even though these appear to be different resources they end up sharing the same underlying hardware and thus does not fulfill the user's request for exclusive use of hardware resources. Fix this by including the CDP peer (if there is one) in every CBM overlap test. This does not impact the overlap between resources within the same exclusive resource group that is allowed.

[ Upstream commit 521348b0 ] Introduce a utility that, when provided with a RDT resource and an instance of this RDT resource (a RDT domain), would return pointers to the RDT resource and RDT domain that share the same hardware. This is specific to the CDP resources that share the same hardware. For example, if a pointer to the RDT_RESOURCE_L2DATA resource (struct rdt_resource) and a pointer to an instance of this resource (struct rdt_domain) is provided, then it will return a pointer to the RDT_RESOURCE_L2CODE resource as well as the specific instance that shares the same hardware as the provided rdt_domain. This utility is created in support of the "exclusive" resource group mode where overlap of resource allocation between resource groups need to be avoided. The overlap test need to consider not just the matching resources, but also the resources that share the same hardware. Temporarily mark it as unused in support of patch testing to avoid compile warnings until it is used. Fixes: 49f7b4ef ("x86/intel_rdt: Enable setting of exclusive mode") Signed-off-by:

[ Upstream commit 3baa8ec8 ] Some SPI controllers can't write nor->page_size bytes in a single step because their TX FIFO is too small, but when that happens we should make sure a WRITE_EN command before each write access and READ_SR command after each write access is issued. The core is already taking care of that, so all we have to do here is return the actual number of bytes that were written during the spi_mem_exec_op() operation. Signed-off-by:

[ Upstream commit 7a55948d ] UUIDs are considered as metadata. __uuid_write should add the number of buckets (in sectors) written to disk to ca->meta_sectors_written. Currently only 1 bucket is used in uuid write. Steps to test: 1) create a fresh backing device and a fresh cache device separately. The backing device didn't attach to any cache set. 2) cd /sys/block/<cache device>/bcache cat metadata_written // record the output value cat bucket_size 3) attach the backing device to cache set 4) cat metadata_written The output value is almost the same as the value in step 2 before the change. After the change, the value is bigger about 1 bucket size. Signed-off-by:

Fix this by moving FB_CMDLINE, FB_NOTIFY, and FB_CLPS711X_OLD to just before the FB Kconfig symbol definition and by moving the omap, omap2, and mmp menus to last, following FB_SM712. Also, the FB_VIA dependencies are duplicated by both being inside an "if FB_VIA/endif" block and "depends on FB_VIA", so drop the "depends on FB_VIA" lines since they are redundant.

[ Upstream commit 60e5e48d ] When a device tree set a display-timing using native-mode then according to the bindings doc this should: native-mode: The native mode for the display, in case multiple modes are provided. When omitted, assume the first node is the native. The atmel_lcdfb used the last timing subnode and did not respect the timing mode specified with native-mode. Introduce use of of_get_videomode() which allowed a nice simplification of the code while also added support for native-mode. As a nice side-effect this fixes a memory leak where the data used for timings and the display_np was not freed. Signed-off-by:

[ Upstream commit 541d7fdd ] The AF_XDP socket struct can exist in three different, implicit states: setup, bound and released. Setup is prior the socket has been bound to a device. Bound is when the socket is active for receive and send. Released is when the process/userspace side of the socket is released, but the sock object is still lingering, e.g. when there is a reference to the socket in an XSKMAP after process termination. The Rx fast-path code uses the "dev" member of struct xdp_sock to check whether a socket is bound or relased, and the Tx code uses the struct xdp_umem "xsk_list" member in conjunction with "dev" to determine the state of a socket. However, the transition from bound to released did not tear the socket down in correct order. On the Rx side "dev" was cleared after synchronize_net() making the synchronization useless. On the Tx side, the internal queues were destroyed prior removing them from the "xsk_list". This commit corrects the cleanup order, and by doing so xdp_del_sk_umem() can be simplified and one synchronize_net() can be removed. Fixes: 965a9909 ("xsk: add support for bind for Rx") Fixes: ac98d8aa ("xsk: wire upp Tx zero-copy functions") Reported-by:
