[ Upstream commit ece27a33 ] Currently, the clock duty is set as tLOW/tHIGH = 1/1. For Fast-mode, tLOW is set to 1.25 us while the I2C spec requires tLOW >= 1.3 us. tLOW/tHIGH = 5/4 would meet both Standard-mode and Fast-mode: Standard-mode: tLOW = 5.56 us, tHIGH = 4.44 us Fast-mode: tLOW = 1.39 us, tHIGH = 1.11 us Signed-off-by:

[ Upstream commit 0544ee4b ] Some AMD based HP laptops have a SMB0001 ACPI device node which does not define any methods. This leads to the following error in dmesg: [ 5.222731] cmi: probe of SMB0001:00 failed with error -5 This commit makes acpi_smbus_cmi_add() return -ENODEV instead in this case silencing the error. In case of a failure of the i2c_add_adapter() call this commit now propagates the error from that call instead of -EIO. Signed-off-by:

[ Upstream commit 6c7f25ca ] According to Intel (R) Axxia TM Lionfish Communication Processor Peripheral Subsystem Hardware Reference Manual, the AXXIA I2C module have a programmable Master Wait Timer, which among others, checks the time between commands send in manual mode. When a timeout (25ms) passes, TSS bit is set in Master Interrupt Status register and a Stop command is issued by the hardware. The axxia_i2c_xfer(), does not properly handle this situation, however. For each message a separate axxia_i2c_xfer_msg() is called and this function incorrectly assumes that any interrupt might happen only when waiting for completion. This is mostly correct but there is one exception - a master timeout can trigger if enough time has passed between individual transfers. It will, by definition, happen between transfers when the interrupts are disabled by the code. If that happens, the hardware issues Stop command. The interrupt indicating timeout will not be triggered as soon as we enable them since the Master Interrupt Status is cleared when master mode is entered again (which happens before enabling irqs) meaning this error is lost and the transfer is continued even though the Stop was issued on the bus. The subsequent operations completes without error but a bogus value (0xFF in case of read) is read as the client device is confused because aborted transfer. No error is returned from master_xfer() making caller believe that a valid value was read. To fix the problem, the TSS bit (indicating timeout) in Master Interrupt Status register is checked before each transfer. If it is set, there was a timeout before this transfer and (as described above) the hardware already issued Stop command so the transaction should be aborted thus -ETIMEOUT is returned from the master_xfer() callback. In order to be sure no timeout was issued we can't just read the status just before starting new transaction as there will always be a small window of time (few CPU cycles at best) where this might still happen. For this reason we have to temporally disable the timer before checking for TSS bit. Disabling it will, however, clear the TSS bit so in order to preserve that information, we have to read it in ISR so we have to ensure that the TSS interrupt is not masked between transfers of one transaction. There is no need to call bus recovery or controller reinitialization if that happens so it's skipped. Signed-off-by:

[ Upstream commit 993107fe ] When deleting a VLAN device using an ioctl the netdev is unregistered before the VLAN filter is updated via ndo_vlan_rx_kill_vid(). It can lead to a use-after-free in mlxsw in case the VLAN device is deleted while being enslaved to a bridge. The reason for the above is that when mlxsw receives the CHANGEUPPER event, it wrongly assumes that the VLAN device is no longer its upper and thus destroys the internal representation of the bridge port despite the reference count being non-zero. Fix this by checking if the VLAN device is our upper using its real device. In net-next I'm going to remove this trick and instead make mlxsw completely agnostic to the order of the events.

[ Upstream commit c38f57da ] If a local process has closed a connected socket and hasn't received a RST packet yet, then the socket remains in the table until a timeout expires. When a vhost_vsock instance is released with the timeout still pending, the socket is never freed because vhost_vsock has already set the SOCK_DONE flag. Check if the close timer is pending and let it close the socket. This prevents the race which can leak sockets. Reported-by:

[ Upstream commit b5fd2e00 ] A "short" ARS (address range scrub) instructs the platform firmware to return known errors. In contrast, a "long" ARS instructs platform firmware to arrange every data address on the DIMM to be read / checked for poisoned data. The conversion of the flags in commit d3abaf43 "acpi, nfit: Fix Address Range Scrub completion tracking", changed the meaning of passing '0' to acpi_nfit_ars_rescan(). Previously '0' meant "not short", now '0' is ARS_REQ_SHORT. Pass ARS_REQ_LONG to restore the expected scrub-type behavior of user-initiated ARS sessions.

[ 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 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:

Other filesystems that implement direct_IO handle this; most use blockdev_direct_IO(). ceph and cifs have similar logic. mount 127.0.0.1:/export /nfs dd if=/dev/zero of=/nfs/image bs=1M count=200 losetup --direct-io=on -f /nfs/image mkfs.btrfs /dev/loop0 mount -t btrfs /dev/loop0 /mnt/ kernel: WARNING: CPU: 0 PID: 8067 at fs/buffer.c:580 __set_page_dirty+0xaf/0xd0 kernel: Modules linked in: loop(E) nfsv3(E) rpcsec_gss_krb5(E) nfsv4(E) dns_resolver(E) nfs(E) fscache(E) nfsd(E) auth_rpcgss(E) nfs_acl(E) lockd(E) grace(E) fuse(E) tun(E) ip6t_rpfilter(E) ipt_REJECT(E) nf_ kernel: snd_seq(E) snd_seq_device(E) snd_pcm(E) video(E) snd_timer(E) snd(E) soundcore(E) ip_tables(E) xfs(E) libcrc32c(E) sd_mod(E) sr_mod(E) cdrom(E) ata_generic(E) pata_acpi(E) crc32c_intel(E) ahci(E) li kernel: CPU: 0 PID: 8067 Comm: kworker/0:2 Tainted: G E 4.20.0-rc1.master.20181111.ol7.x86_64 #1 kernel: Hardware name: innotek GmbH VirtualBox/VirtualBox, BIOS VirtualBox 12/01/2006 kernel: Workqueue: nfsiod rpc_async_release [sunrpc] kernel: RIP: 0010:__set_page_dirty+0xaf/0xd0 kernel: Code: c3 48 8b 02 f6 c4 04 74 d4 48 89 df e8 ba 05 f7 ff 48 89 c6 eb cb 48 8b 43 08 a8 01 75 1f 48 89 d8 48 8b 00 a8 04 74 02 eb 87 <0f> 0b eb 83 48 83 e8 01 eb 9f 48 83 ea 01 0f 1f 00 eb 8b 48 83 e8 kernel: RSP: 0000:ffffc1c8825b7d78 EFLAGS: 00013046 kernel: RAX: 000fffffc0020089 RBX: fffff2b603308b80 RCX: 0000000000000001 kernel: RDX: 0000000000000001 RSI: ffff9d11478115c8 RDI: ffff9d11478115d0 kernel: RBP: ffffc1c8825b7da0 R08: 0000646f6973666e R09: 8080808080808080 kernel: R10: 0000000000000001 R11: 0000000000000000 R12: ffff9d11478115d0 kernel: R13: ffff9d11478115c8 R14: 0000000000003246 R15: 0000000000000001 kernel: FS: 0000000000000000(0000) GS:ffff9d115ba00000(0000) knlGS:0000000000000000 kernel: CS: 0010 DS: 0000 ES: 0000 CR0: 0000000080050033 kernel: CR2: 00007f408686f640 CR3: 0000000104d8e004 CR4: 00000000000606f0 kernel: DR0: 0000000000000000 DR1: 0000000000000000 DR2: 0000000000000000 kernel: DR3: 0000000000000000 DR6: 00000000fffe0ff0 DR7: 0000000000000400 kernel: Call Trace: kernel: __set_page_dirty_buffers+0xb6/0x110 kernel: set_page_dirty+0x52/0xb0 kernel: nfs_direct_read_completion+0xc4/0x120 [nfs] kernel: nfs_pgio_release+0x10/0x20 [nfs] kernel: rpc_free_task+0x30/0x70 [sunrpc] kernel: rpc_async_release+0x12/0x20 [sunrpc] kernel: process_one_work+0x174/0x390 kernel: worker_thread+0x4f/0x3e0 kernel: kthread+0x102/0x140 kernel: ? drain_workqueue+0x130/0x130 kernel: ? kthread_stop+0x110/0x110 kernel: ret_from_fork+0x35/0x40 kernel: ---[ end trace 01341980905412c9 ]--- Signed-off-by:

[ Upstream commit c0f53771 ] The function lio_vf_rep_packet_sent_callback releases the occupation of sc via octeon_free_soft_command. sc should not be used after that. Unfortunately, sc->iq_no is read. To fix this, the patch stores sc->iq_no into a local variable before releasing sc and then uses the local variable instead of sc->iq_no. Signed-off-by:
