[ Upstream commit 12750d16 ] [Why] YCbCr420 packing format uses two chanels for luma, and 1 channel for both chroma component. Our previous implementation did not account for this and results in every other pixel having very high luma value, showing greyish color instead of black. YCbCr444 = <Y1, Cb1, Cr1>; <Y2, Cb2, Cr2> ..... YCbCr420 = <Y1, Y2, Cb1>; <Y3, Y4, Cr1> ..... [How] Program the second channel with the black color value for luma as well. Signed-off-by:

However the driver doesn't enable the timer for peripheral port, then the peripheral port is unable to be enumerated by a host if the other usb port is disabled or in peripheral mode too. So let's start the timer for peripheral port too. Fixes: ea2f35c0 ("usb: musb: Fix sleeping function called from invalid context for hdrc glue") Acked-by:

[ Upstream commit 6010abf2 ] Due to lack of ID pin interrupt event on AM335x devices, the musb dsps driver uses polling to detect usb device attach for dual-role port. But in the case if a micro-A cable adapter is attached without a USB device attached to the cable, the musb state machine gets stuck in a_wait_vrise state waiting for the MUSB_CONNECT interrupt which won't happen due to the usb device is not attached. The state is stuck in a_wait_vrise even after the micro-A cable is detached, which could cause VBUS retention if then the dual-role port is attached to a host port. To fix the problem, make a_wait_vrise as a transient state, then move the state to either a_wait_bcon for host port or a_idle state for dual-role port, if no usb device is attached to the port.

[ Upstream commit 0d640732 ] When we emulate an MMIO instruction, we advance the CPU state within decode_hsr(), before emulating the instruction effects. Having this logic in decode_hsr() is opaque, and advancing the state before emulation is problematic. It gets in the way of applying consistent single-step logic, and it prevents us from being able to fail an MMIO instruction with a synchronous exception. Clean this up by only advancing the CPU state *after* the effects of the instruction are emulated. Cc: Peter Maydell <peter.maydell@linaro.org> Reviewed-by:

[ Upstream commit 36d65be9 ] When bringing up a device, the code checks to see if the number of MSIX has changed. pci_disable_msix() should be called first before changing the number of reserved NQs/CMPL rings. This ensures that the MSIX vectors associated with the NQs/CMPL rings are still properly mapped when pci_disable_msix() masks the vectors. This patch will prevent errors when RDMA support is added for the new 57500 chips. When the RDMA driver shuts down, the number of NQs is decreased and we must use the new sequence to prevent MSIX errors. Signed-off-by:

In this case the 'target' buffer is coming from a list of build-ids that are expected to have a len of at most (SBUILD_ID_SIZE - 1) chars, so probably we're safe, but since we're using strncpy() here, use strlcpy() instead to provide the intended safety checking without the using the problematic strncpy() function.

[ Upstream commit 3cd24c69 ] Snapshot is expected to be fast. But if there are writers steadily creating dirty pages in our subvolume, the snapshot may take a very long time to complete. To fix the problem, we use tagged writepage for snapshot flusher as we do in the generic write_cache_pages(), so we can omit pages dirtied after the snapshot command. This does not change the semantics regarding which data get to the snapshot, if there are pages being dirtied during the snapshotting operation. There's a sync called before snapshot is taken in old/new case, any IO in flight just after that may be in the snapshot but this depends on other system effects that might still sync the IO. We do a simple snapshot speed test on a Intel D-1531 box: fio --ioengine=libaio --iodepth=32 --bs=4k --rw=write --size=64G --direct=0 --thread=1 --numjobs=1 --time_based --runtime=120 --filename=/mnt/sub/testfile --name=job1 --group_reporting & sleep 5; time btrfs sub snap -r /mnt/sub /mnt/snap; killall fio original: 1m58sec patched: 6.54sec This is the best case for this patch since for a sequential write case, we omit nearly all pages dirtied after the snapshot command. For a multi writers, random write test: fio --ioengine=libaio --iodepth=32 --bs=4k --rw=randwrite --size=64G --direct=0 --thread=1 --numjobs=4 --time_based --runtime=120 --filename=/mnt/sub/testfile --name=job1 --group_reporting & sleep 5; time btrfs sub snap -r /mnt/sub /mnt/snap; killall fio original: 15.83sec patched: 10.35sec The improvement is smaller compared to the sequential write case, since we omit only half of the pages dirtied after snapshot command.

[ Upstream commit dd1f2250 ] Some callers of sci_submit_rx() hold the port spinlock, others don't. During fallback to PIO, the driver needs to obtain the port spinlock. If the lock was already held, spinlock recursion is detected, causing a deadlock: BUG: spinlock recursion on CPU#0. Fix this by adding a flag parameter to sci_submit_rx() for the caller to indicate the port spinlock is already held, so spinlock recursion can be avoided. Move the spin_lock_irqsave() up, so all DMA disable steps are protected, which is safe as the recently introduced dmaengine_terminate_async() can be called in atomic context. Signed-off-by:

[ Upstream commit a9261d41 ] It's not that impossible to imagine that a device OR a btrfs image is copied just by using the dd or the cp command. Which in case both the copies of the btrfs will have the same fsid. If on the system with automount enabled, the copied FS gets scanned. We have a known bug in btrfs, that we let the device path be changed after the device has been mounted. So using this loop hole the new copied device would appears as if its mounted immediately after it's been copied. For example: Initially.. /dev/mmcblk0p4 is mounted as / $ lsblk NAME MAJ:MIN RM SIZE RO TYPE MOUNTPOINT mmcblk0 179:0 0 29.2G 0 disk |-mmcblk0p4 179:4 0 4G 0 part / |-mmcblk0p2 179:2 0 500M 0 part /boot |-mmcblk0p3 179:3 0 256M 0 part [SWAP] `-mmcblk0p1 179:1 0 256M 0 part /boot/efi $ btrfs fi show Label: none uuid: 07892354-ddaa-4443-90ea-f76a06accaba Total devices 1 FS bytes used 1.40GiB devid 1 size 4.00GiB used 3.00GiB path /dev/mmcblk0p4 Copy mmcblk0 to sda $ dd if=/dev/mmcblk0 of=/dev/sda And immediately after the copy completes the change in the device superblock is notified which the automount scans using btrfs device scan and the new device sda becomes the mounted root device. $ lsblk NAME MAJ:MIN RM SIZE RO TYPE MOUNTPOINT sda 8:0 1 14.9G 0 disk |-sda4 8:4 1 4G 0 part / |-sda2 8:2 1 500M 0 part |-sda3 8:3 1 256M 0 part `-sda1 8:1 1 256M 0 part mmcblk0 179:0 0 29.2G 0 disk |-mmcblk0p4 179:4 0 4G 0 part |-mmcblk0p2 179:2 0 500M 0 part /boot |-mmcblk0p3 179:3 0 256M 0 part [SWAP] `-mmcblk0p1 179:1 0 256M 0 part /boot/efi $ btrfs fi show / Label: none uuid: 07892354-ddaa-4443-90ea-f76a06accaba Total devices 1 FS bytes used 1.40GiB devid 1 size 4.00GiB used 3.00GiB path /dev/sda4 The bug is quite nasty that you can't either unmount /dev/sda4 or /dev/mmcblk0p4. And the problem does not get solved until you take sda out of the system on to another system to change its fsid using the 'btrfstune -u' command. Signed-off-by:

[ Upstream commit 07d40576 ] If the user issues an "mmc extcsd read", the SD controller receives what it thinks is a SEND_IF_COND command with an unexpected data block. The resulting operations leave the FSM stuck in READWAIT, a state which persists until the MMC framework resets the controller, by which point the root filesystem is likely to have been unmounted. A less heavyweight solution is to detect the condition and nudge the FSM by asserting the (self-clearing) FORCE_DATA_MODE bit. Link: https://github.com/raspberrypi/linux/issues/2728Signed-off-by:

WARNING: vmlinux.o(.text+0xf824): Section mismatch in reference from the function zeus_register_ohci() to the function .init.text:pxa_set_ohci_info() The function zeus_register_ohci() references the function __init pxa_set_ohci_info(). This is often because zeus_register_ohci lacks a __init annotation or the annotation of pxa_set_ohci_info is wrong. WARNING: vmlinux.o(.text+0xf95c): Section mismatch in reference from the function cm_x300_init_u2d() to the function .init.text:pxa3xx_set_u2d_info() The function cm_x300_init_u2d() references the function __init pxa3xx_set_u2d_info(). This is often because cm_x300_init_u2d lacks a __init annotation or the annotation of pxa3xx_set_u2d_info is wrong. Signed-off-by:

[ Upstream commit a0517a0f ] For some reason, my older GCC (< 4.8) isn't smart enough to optimize the !__builtin_constant_p() branch in bpf_htons, I see: error: implicit declaration of function '__builtin_bswap16' Let's use __bpf_constant_htons as suggested by Daniel Borkmann. I tried to use simple htons, but it produces the following: test_progs.c:54:17: error: braced-group within expression allowed only inside a function .eth.h_proto = htons(ETH_P_IP), Signed-off-by:

[ Upstream commit e4a7dca5 ] In the ioctl_event_ctl() SWITCHTEC_IOCTL_EVENT_IDX_ALL case, we call event_ctl() several times with the same "ctl" struct. Each call clobbers ctl.flags, which leads to the problem that we may not actually enable or disable all events as the user requested. Preserve the event flag value with a temporary variable. Fixes: 52eabba5 ("switchtec: Add IOCTLs to the Switchtec driver") Signed-off-by:

[ Upstream commit d7263ab3 ] In Spectrum-2, higher priority value wins and priority valid values are in the range of {1,cap_kvd_size-1}. mlxsw_sp_acl_tcam_priority_get converts from lower-bound priorities alike tc flower to Spectrum-2 HW range. Up until now tc flower did not provide priority 0 or reached the maximal value, however multicast routing does provide priority 0. Therefore, Change mlxsw_sp_acl_tcam_priority_get to verify priority is in the correct range. Make sure priority is never set to zero and never exceeds the maximal allowed value. Signed-off-by:
