[ Upstream commit 3d0358d0 ] Chris has discovered and reported that v7_dma_inv_range() may corrupt memory if address range is not aligned to cache line size. Since the whole cache-v7m.S was lifted form cache-v7.S the same observation applies to v7m_dma_inv_range(). So the fix just mirrors what has been done for v7 with a little specific of M-class.

[ Upstream commit a1208f6a ] This patch addresses possible memory corruption when v7_dma_inv_range(start_address, end_address) address parameters are not aligned to whole cache lines. This function issues "invalidate" cache management operations to all cache lines from start_address (inclusive) to end_address (exclusive). When start_address and/or end_address are not aligned, the start and/or end cache lines are first issued "clean & invalidate" operation. The assumption is this is done to ensure that any dirty data addresses outside the address range (but part of the first or last cache lines) are cleaned/flushed so that data is not lost, which could happen if just an invalidate is issued. The problem is that these first/last partial cache lines are issued "clean & invalidate" and then "invalidate". This second "invalidate" is not required and worse can cause "lost" writes to addresses outside the address range but part of the cache line. If another component writes to its part of the cache line between the "clean & invalidate" and "invalidate" operations, the write can get lost. This fix is to remove the extra "invalidate" operation when unaligned addressed are used. A kernel module is available that has a stress test to reproduce the issue and a unit test of the updated v7_dma_inv_range(). It can be downloaded from http://ftp.sageembedded.com/outgoing/linux/cache-test-20181107.tgz. v7_dma_inv_range() is call by dmac_[un]map_area(addr, len, direction) when the direction is DMA_FROM_DEVICE. One can (I believe) successfully argue that DMA from a device to main memory should use buffers aligned to cache line size, because the "clean & invalidate" might overwrite data that the device just wrote using DMA. But if a driver does use unaligned buffers, at least this fix will prevent memory corruption outside the buffer. Signed-off-by:

[ Upstream commit c3494801 ] Malicious user space may try to force the verifier to use as much cpu time and memory as possible. Hence check for pending signals while verifying the program. Note that suspend of sys_bpf(PROG_LOAD) syscall will lead to EAGAIN, since the kernel has to release the resources used for program verification. Reported-by:

[ Upstream commit 6c3516fe ] I noticed that the Android v3.0.8 kernel on droid4 is using different keypad values from the mainline kernel and does not have issues with keys occasionally being stuck until pressed again. Turns out there was an earlier patch posted to fix this as "Input: omap-keypad: errata i689: Correct debounce time", but it was never reposted to fix use macros for timing calculations. This updated version is using macros, and also fixes the use of the input clock rate to use 32768KiHz instead of 32000KiHz. And we want to use the known good Android kernel values of 3 and 6 instead of 2 and 6 in the earlier patch. Reported-by:

[ Upstream commit ee445635 ] SoCs that contain MDP5 have a top level wrapper called MDSS that manages locks, power and irq for the sub-blocks within it. Irq for HDMI is also routed through the MDSS. Shortly after the Hot Plug Detection (HPD) is enabled in HDMI, HDMI interrupts are recieved by the MDSS interrupt handler. However at this moment the HDMI irq is still not mapped to the MDSS irq domain so the HDMI irq handler cannot be called to process the interrupts. This leads to a flood of HDMI interrupts on CPU 0. If we are lucky to have the HDMI initialization running on a different CPU, it will eventually map the HDMI irq to MDSS irq domain, the next HDMI interrupt will be handled by the HDMI irq handler, the interrupt flood will stop and we will recover. If the HDMI initialization is running on CPU 0, then it cannot complete and there is nothing to stop the interrupt flood on CPU 0. The system is stuck. Fix this by moving the HPD enablement after the HDMI irq is mapped to the MDSS irq domain. Signed-off-by:

[ Upstream commit 3b5b3a33 ] Previously when unbinding a slave the 802.3ad implementation only told partner that the port is not suitable for aggregation by setting the port aggregation state from aggregatable to individual. This is not enough. If the physical layer still stays up and we only unbinded this port from the bond there is nothing in the aggregation status alone to prevent the partner from sending traffic towards us. To ensure that the partner doesn't consider this port at all anymore we should also disable collecting and distributing to signal that this actor is going away. Also clear AD_STATE_SYNCHRONIZATION to ensure partner exits collecting + distributing state. I have tested this behaviour againts Arista EOS switches with mlx5 cards (physical link stays up even when interface is down) and simulated the same situation virtually Linux <-> Linux with two network namespaces running two veth device pairs. In both cases setting aggregation to individual doesn't alone prevent traffic from being to sent towards this port given that the link stays up in partners end. Partner still keeps it's end in collecting + distributing state and continues until timeout is reached. In most cases this means we are losing the traffic partner sends towards our port while we wait for timeout. This is most visible with slow periodic time (LACP rate slow). Other open source implementations like Open VSwitch and libreswitch, and vendor implementations like Arista EOS, seem to disable collecting + distributing to when doing similar port disabling/detaching/removing change. With this patch kernel implementation would behave the same way and ensure partner doesn't consider our actor viable anymore. Signed-off-by:

[ Upstream commit 5f2b8b62 ] Setting up and tearing down debugfs is current unbalanced, as seen by this error during resume from suspend: [ 752.134067] dwc-eth-dwmac 2490000.ethernet eth0: ERROR failed to create debugfs directory [ 752.134347] dwc-eth-dwmac 2490000.ethernet eth0: stmmac_hw_setup: failed debugFS registration The imbalance happens because the driver creates the debugfs hierarchy when the device is opened and tears it down when the device is closed. There's little gain in that, and it could be argued that it is even surprising because it's not usually done for other devices. Fix the imbalance by moving the debugfs creation and teardown to the driver's ->probe() and ->remove() implementations instead. Note that the ring descriptors cannot be read while the interface is down, so make sure to return an empty file when the descriptors_status debugfs file is read. Signed-off-by:

[ Upstream commit 10d44343 ] Some ARC CPU's do not support unaligned loads/stores. Currently, generic implementation of reads{b/w/l}()/writes{b/w/l}() is being used with ARC. This can lead to misfunction of some drivers as generic functions do a plain dereference of a pointer that can be unaligned. Let's use {get/put}_unaligned() helpers instead of plain dereference of pointer in order to fix. The helpers allow to get and store data from an unaligned address whilst preserving the CPU internal alignment. According to [1], the use of these helpers are costly in terms of performance so we added an initial check for a buffer already aligned so that the usage of the helpers can be avoided, when possible.

[ Upstream commit 88113957 ] In commit 26a4676f ("arm64: mm: define NET_IP_ALIGN to 0"), AVE controller affects this modification because the controller forces to ignore lower 2bits of buffer start address, and make 2-byte headroom, that is, data reception starts from (buffer + 2). This patch defines AVE_FRAME_HEADROOM macro as hardware-specific value, and replaces NET_IP_ALIGN with it. Signed-off-by:
