2017-11-29rxrpc: Fix ACK generation from the connection event processorDavid Howells1-21/+29
Repeat terminal ACKs and now terminal ACKs are now generated from the connection event processor rather from call handling as this allows us to discard client call structures as soon as possible and free up the channel for a follow on call. However, in ACKs so generated, the additional information trailer is malformed because the padding that's meant to be in the middle isn't included in what's transmitted. Fix it so that the 3 bytes of padding are included in the transmission. Further, the trailer is misaligned because of the padding, so assigment to the u16 and u32 fields inside it might cause problems on some arches, so fix this by breaking the padding and the trailer out of the packed struct. (This also deals with potential compiler weirdies where some of the nested structs are packed and some aren't). The symptoms can be seen in wireshark as terminal DUPLICATE or IDLE ACK packets in which the Max MTU, Interface MTU and rwind fields have weird values and the Max Packets field is apparently missing.

2017-11-29eeprom: at24: correctly set the size for at24mac402Bartosz Golaszewski1-0/+10
There's an ilog2() expansion in AT24_DEVICE_MAGIC() which rounds down the actual size of EUI-48 byte array in at24mac402 eeproms to 4 from 6, making it impossible to read it all. Fix it by manually adjusting the value in probe(). This patch contains a temporary fix that is suitable for stable branches. Eventually we'll probably remove the call to ilog2() while converting the magic values to actual structs.

2017-11-29drm/atomic: make drm_atomic_helper_wait_for_vblanks more agressiveLucas Stach1-1/+1
drm_atomic_helper_setup_commit expects that flipping of previous commits has happened when it is called to set up a new commit. This can be violated by commits where userspace doesn't get a flip completion event to synchronize against i.e. legacy modesets and property changes. The expectation is that those are done by blocking commits, which wait for completion. Most drivers call drm_atomic_helper_wait_for_vblanks in the commit_tail to ensure completion, but the wait for next vblank might not actually happen if the commit didn't change any planes. Make the wait more agressive by also waiting if no planes changed. This is the minimal regression fix for the 4.15 kernel series. Long term drivers should switch away from drm_atomic_helper_wait_for_vblanks and use drm_atomic_helper_wait_for_flip_done instead.

The direction_output callback of the gpio_chip structure is supposed to set the output direction but also to set the value of the gpio.

2017-11-29powerpc: Avoid signed to unsigned conversion in set_thread_tidr()Vaibhav Jain1-3/+6
There is an unsafe signed to unsigned conversion in set_thread_tidr() that may cause an error value to be assigned to SPRN_TIDR register and used as thread-id. The issue happens as assign_thread_tidr() returns an int and thread.tidr is an unsigned-long. So a negative error code returned from assign_thread_tidr() will fail the error check and gets assigned as tidr as a large positive value. To fix this the patch assigns the return value of assign_thread_tidr() to a temporary int and assigns it to thread.tidr iff its '> 0'. The patch shouldn't impact the calling convention of set_thread_tidr() i.e all -ve return-values are error codes and a return value of '0' indicates success.

2017-11-29vsprintf: add printk specifier %pxTobin C. Harding3-2/+36
printk specifier %p now hashes all addresses before printing. Sometimes we need to see the actual unmodified address. This can be achieved using %lx but then we face the risk that if in future we want to change the way the Kernel handles printing of pointers we will have to grep through the already existent 50 000 %lx call sites. Let's add specifier %px as a clear, opt-in, way to print a pointer and maintain some level of isolation from all the other hex integer output within the Kernel.

2017-11-29printk: hash addresses printed with %pTobin C. Harding3-46/+155
Currently there exist approximately 14 000 places in the kernel where addresses are being printed using an unadorned %p. This potentially leaks sensitive information regarding the Kernel layout in memory. Many of these calls are stale, instead of fixing every call lets hash the address by default before printing. This will of course break some users, forcing code printing needed addresses to be updated. Code that _really_ needs the address will soon be able to use the new printk specifier %px to print the address. For what it's worth, usage of unadorned %p can be broken down as follows (thanks to Joe Perches). $ git grep -E '%p[^A-Za-z0-9]' | cut -f1 -d"/" | sort | uniq -c 1084 arch 20 block 10 crypto 32 Documentation 8121 drivers 1221 fs 143 include 101 kernel 69 lib 100 mm 1510 net 40 samples 7 scripts 11 security 166 sound 152 tools 2 virt Add function ptr_to_id() to map an address to a 32 bit unique identifier.

Within atomic check, dm_update_crtcs_state is called twice. First to remove from the dc_state, and subsequently to add to it. In both calls, a secondary mode-change check is done using dc-level states. We shouldn't be doing this while removing, since a new dc_stream_state has not been created to do the necessary comparison. Because of this, the mode_changed flag within the DRM state can be mistakenly set to false. Doing so only when adding prevents this. We are also guaranteed that a call to add will come after remove, or else the atomic check fails (and a commit will not happen).

2017-11-28drm/amd/display: Add timing validation against dongle capEric Yang4-3/+91
For DP active dongles, the dpcd dongle caps are read but not used to validate mode timing. This addresses this. In particular, this change fixes light up on the HDMI 4k TV connected through DP active dongle. Since the 4k TV defaults to YCbCr420, which the dongle don't support. This change does not address MST cases, a more generalized approach must be taken for that.
