[ Upstream commit bd1cd0eb ] AU0828_DEVICE() macro in quirks-table.h uses USB_DEVICE_VENDOR_SPEC() for expanding idVendor and idProduct fields. However, the latter macro adds also match_flags and bInterfaceClass, which are different from the values AU0828_DEVICE() macro sets after that. For fixing them, just expand idVendor and idProduct fields manually in AU0828_DEVICE(). This fixes sparse warnings like: sound/usb/quirks-table.h:2892:1: warning: Initializer entry defined twice Signed-off-by:

[ Upstream commit 5df816e7 ] When initializing the device (procedure init_one), the driver calls mlx5_pci_init to perform pci initialization. As part of this initialization, mlx5_pci_init creates a debugfs directory. If this creation fails, init_one aborts, returning failure to the caller (which is the probe method caller). The main reason for such a failure to occur is if the debugfs directory already exists. This can happen if the last time mlx5_pci_close was called, debugfs_remove (silently) failed due to the debugfs directory not being empty. Guarantee that such a debugfs_remove failure will not occur by instead calling debugfs_remove_recursive in procedure mlx5_pci_close.

[ Upstream commit 76d5581c ] When the mlx5 health mechanism detects a problem while the driver is in the middle of init_one or remove_one, the driver needs to prevent the health mechanism from scheduling future work; if future work is scheduled, there is a problem with use-after-free: the system WQ tries to run the work item (which has been freed) at the scheduled future time. Prevent this by disabling work item scheduling in the health mechanism when the driver is in the middle of init_one() or remove_one().

[ Upstream commit cc4dfb7f ] When a rds sock is bound, it is inserted into the bind_hash_table which is protected by RCU. But when releasing rds sock, after it is removed from this hash table, it is freed immediately without respecting RCU grace period. This could cause some use-after-free as reported by syzbot. Mark the rds sock with SOCK_RCU_FREE before inserting it into the bind_hash_table, so that it would be always freed after a RCU grace period. The other problem is in rds_find_bound(), the rds sock could be freed in between rhashtable_lookup_fast() and rds_sock_addref(), so we need to extend RCU read lock protection in rds_find_bound() to close this race condition.

commit 7a9cdebd upstream. Jann Horn points out that the vmacache_flush_all() function is not only potentially expensive, it's buggy too. It also happens to be entirely unnecessary, because the sequence number overflow case can be avoided by simply making the sequence number be 64-bit. That doesn't even grow the data structures in question, because the other adjacent fields are already 64-bit. So simplify the whole thing by just making the sequence number overflow case go away entirely, which gets rid of all the complications and makes the code faster too. Win-win. [ Oleg Nesterov points out that the VMACACHE_FULL_FLUSHES statistics also just goes away entirely with this ] Reported-by:

commit 0633da48 upstream. autofs_sbi() does not check the superblock magic number to verify it has been given an autofs super block. Backport Note: autofs4 has been renamed to autofs upstream. As a result the upstream patch does not apply cleanly onto 4.14.y.

commit 44a182b9 upstream. KASAN found a use-after-free in xhci_free_virt_device+0x33b/0x38e where xhci_free_virt_device() sets slot id to 0 if udev exists: if (dev->udev && dev->udev->slot_id) dev->udev->slot_id = 0; dev->udev will be true even if udev is freed because dev->udev is not set to NULL. set dev->udev pointer to NULL in xhci_free_dev() The original patch went to stable so this fix needs to be applied there as well.

In that case, it is appropriate to return NFS4ERR_NOMATCHING_LAYOUT rather than NFS4ERR_DELAY, as the latter can end up deadlocking. Signed-off-by:

[ Upstream commit 14cb2c8a ] The if-block that sets a successful return value in aix_partition() uses 'lvip[].pps_per_lv' and 'n[].name' potentially uninitialized. For example, if 'numlvs' is zero or alloc_lvn() fails, neither is initialized, but are used anyway if alloc_pvd() succeeds after it. So, make the alloc_pvd() call conditional on their initialization. This has been hit when attaching an apparently corrupted/stressed AIX LUN, misleading the kernel to pr_warn() invalid data and hang.

[ Upstream commit 4faeaf9c ] Look up of buffers in s5p_mfc_handle_frame_new, s5p_mfc_handle_frame_copy_time functions is not working properly for DMA addresses above 2 GiB. As a result flags and timestamp of returned buffers are not set correctly and it breaks operation of GStreamer/OMX plugins which rely on the CAPTURE buffer queue flags. Due to improper return type of the get_dec_y_adr, get_dspl_y_adr callbacks and sign bit extension these callbacks return incorrect address values, e.g. 0xfffffffffefc0000 instead of 0x00000000fefc0000. Then the statement: "if (vb2_dma_contig_plane_dma_addr(&dst_buf->b->vb2_buf, 0) == dec_y_addr)" is always false, which breaks looking up capture queue buffers. To ensure proper matching by address u32 type is used for the DMA addresses. This should work on all related SoCs, since the MFC DMA address width is not larger than 32-bit. Changes done in this patch are minimal as there is a larger patch series pending refactoring the whole driver. Signed-off-by:

[ Upstream commit 36f5d9ef ] The driver only registers one input device, which uses the screen parameters from the first T9 instance. The first T63 instance also uses those parameters. It is incorrect to send input reports from the second instances of these objects if they are enabled: the input scaling will be wrong and the positions will be mashed together. This also causes problems on Android if the number of slots exceeds 32. In the future, this could be handled by looking for enabled touch object instances and creating an input device for each one.

[ Upstream commit 08193d1a ] The function dcb_app_lookup walks the list of specified DCB APP entries, looking for one that matches a given criteria: ifindex, selector, protocol ID and optionally also priority. The "don't care" value for priority is set to 0, because that priority has not been allowed under CEE regime, which predates the IEEE standardization. Under IEEE, 0 is a valid priority number. But because dcb_app_lookup considers zero a wild card, attempts to add an APP entry with priority 0 fail when other entries exist for a given ifindex / selector / PID triplet. Fix by changing the wild-card value to -1. Signed-off-by:

[ Upstream commit 4b270a8c ] In synchronous scenario, like in checkpoint(), we are going to flush dirty node pages to device synchronously, we can easily failed writebacking node page due to trylock_page() failure, especially in condition of intensive lock competition, which can cause long latency of checkpoint(). So let's use lock_page() in synchronous scenario to avoid this issue. Signed-off-by:

[ Upstream commit 4bf4eed4 ] If ioh_gpio_probe() fails on devm_irq_alloc_descs() then chip may point to any element of chip_save array, so reverse iteration from pointer chip may become chip_save[-1] and gpiochip_remove() will operate with wrong memory. The patch fix the error path of ioh_gpio_probe() to correctly bypass chip_save array. Found by Linux Driver Verification project (linuxtesting.org). Signed-off-by:

[ Upstream commit 673bc519 ] The tx completion of multiple mgmt frames can be bundled in a single event and sent by the firmware to host, if this capability is not disabled explicitly by the host. If the host cannot handle the bundled mgmt tx completion, this capability support needs to be disabled in the wmi init cmd, sent to the firmware. Add the host capability indication flag in the wmi ready command, to let firmware know the features supported by the host driver. This field is ignored if it is not supported by firmware. Set the host capability indication flag(i.e. host_capab) to zero, for disabling the support of bundle mgmt tx completion. This will indicate the firmware to send completion event for every mgmt tx completion, instead of bundling them together and sending in a single event.
