Merge tag 'drm-for-v4.14' into dev-4.13

2018-04-19T02:00:20+00:00

This is the DRM tree that was merged into the mainline 4.14 kernel. The ASPEED GFX DRM driver requires functionaliy that was included in this tree, so we merge it back into the 4.13 OpenBMC tree. This should have no impact on other parts of the BMC. Signed-off-by: Joel Stanley

staging: rtl8188eu: Revert 4 commits breaking ARP

2017-11-21T09:24:36+00:00

commit 66d32fdcbf03851724a8b551d490ae1ddfe6eef2 upstream. Commit 2ba8444c97b1 ("staging:r8188eu: move IV/ICV trimming into decrypt() and also place it after rtl88eu_mon_recv_hook()") breaks ARP. After this commit ssh-ing to a laptop with r8188eu wifi no longer works if the machine connecting has never communicated with the laptop before. This is 100% reproducable using "arp -d && ssh " to ssh to a laptop with r8188eu wifi. This commit reverts 4 commits in total: 1. Commit 79650ffde38e ("staging:r8188eu: trim IV/ICV fields in validate_recv_data_frame()") This commit depends on 2 of the other commits being reverted. 2. Commit 02b19b4c4920 ("staging:r8188eu: inline unprotect_frame() in mon_recv_decrypted_recv()") The inline code is wrong the un-inlined version contains: if (skb->len < hdr_len + iv_len + icv_len) return; ... Where as the inline-ed code introduced by this commit does: if (skb->len < hdr_len + iv_len + icv_len) { ... Note the same check, but now to actually continue doing ... instead of to not do it, so this commit is no good. 3. Commit d86e16da6a5d ("staging:r8188eu: use different mon_recv_decrypted() inside rtl88eu_mon_recv_hook() and rtl88eu_mon_xmit_hook().") This commit introduced a 1:1 copy of a function so that one of the 2 copies can be modified in the 2 commits we're already reverting. 4. Commit 2ba8444c97b1 ("staging:r8188eu: move IV/ICV trimming into decrypt() and also place it after rtl88eu_mon_recv_hook()") This is the commit actually breaking ARP. Note this commit is a straight-forward squash of the revert of these 4 commits, without any changes. Cc: Ivan Safonov Signed-off-by: Hans de Goede Signed-off-by: Greg Kroah-Hartman

staging: vboxvideo: Fix reporting invalid suggested-offset-properties

2017-11-21T09:24:36+00:00

commit ce10d7b4e8e3574b9616e54a09d64521b9aeb8b6 upstream. The x and y hints receives from the host are unsigned 32 bit integers and they get set to -1 (0xffffffff) when invalid. Before this commit the vboxvideo driver was storing them in an u16 causing the -1 to be truncated to 65535 which, once reported to userspace, was breaking gnome 3.26+ in Wayland mode. This commit stores the host values in 32 bit variables, removing the truncation and checks for -1, replacing it with 0 as -1 is not a valid suggested-offset-property value. Likewise the properties are now initialized to 0 instead of -1, since -1 is not a valid value. This fixes gnome 3.26+ in Wayland mode not working with the vboxvideo driver.

staging: greybus: spilib: fix use-after-free after deregistration

2017-11-21T09:24:36+00:00

commit 770b03c2ca4aa44d226cf248f86aa23e546147d0 upstream. Remove erroneous spi_master_put() after controller deregistration which would access the already freed spi controller. Note that spi_unregister_master() drops our only controller reference.

staging: ccree: fix 64 bit scatter/gather DMA ops

2017-11-21T09:24:36+00:00

commit e0b3f39092a1cff5548cbaf40096ec25e7721de6 upstream. Fix a wrong offset used in splitting a 64 DMA address to MSB/LSB parts needed for scatter/gather HW descriptors causing operations relying on them to fail on 64 bit platforms.

staging: sm750fb: Fix parameter mistake in poke32

2017-11-21T09:24:36+00:00

commit 16808dcf605e6302319a8c3266789b76d4c0983b upstream. In commit c075b6f2d357ea9 ("staging: sm750fb: Replace POKE32 and PEEK32 by inline functions"), POKE32 has been replaced by the inline function poke32. But it exchange the "addr" and "data" parameters by mistake, so fix it.

staging: wilc1000: Fix bssid buffer offset in Txq

2017-11-21T09:24:36+00:00

commit 1bbf6a6d4091affb27ec0a19d7aa7887ce72f610 upstream. Commit 46949b48568b ("staging: wilc1000: New cfg packet format in handle_set_wfi_drv_handler") updated the frame format sent from host to the firmware. The code to update the bssid offset in the new frame was part of a second patch in the series which did not make it in and thus causes connection problems after associating to an AP. This fix adds the proper offset of the bssid value in the Tx queue buffer to fix the connection issues.

staging: bcm2835-audio: Fix memory corruption

2017-10-27T08:39:08+00:00

commit c97d96b4e612c7dc1b37d7afc61b598a9a25994d upstream. The previous commit (0adbfd46) fixed a memory leak but also freed a block in the success case, causing a stale pointer to be used with potentially fatal results. Only free the vchi_instance block in the case that vchi_connect fails; once connected, the instance is retained for subsequent connections. Simplifying the code by removing a bunch of gotos and returning errors directly.

staging: vchiq_2835_arm: Fix NULL ptr dereference in free_pagelist

2017-10-12T09:56:12+00:00

commit 974d4d03fc020af4fa4e9e72a86f0fefa37803c5 upstream. This fixes a NULL pointer dereference on RPi 2 with multi_v7_defconfig. The function page_address() could return NULL with enabled CONFIG_HIGHMEM. So fix this by using kmap() instead.

staging: iio: ad7192: Fix - use the dedicated reset function avoiding dma from stack.

2017-10-12T09:56:11+00:00

commit f790923f146140a261ad211e5baf75d169f16fb2 upstream. Depends on: 691c4b95d1 ("iio: ad_sigma_delta: Implement a dedicated reset function") SPI host drivers can use DMA to transfer data, so the buffer should be properly allocated. Keeping it on the stack could cause an undefined behavior. The dedicated reset function solves this issue.
