[PATCH] usb: dwc3: gadget: Properly check last unaligned/zero chain TRB

by Thinh Nguyen

Current check for the last extra TRB for zero and unaligned transfers does not account for isoc OUT. The last TRB of the Buffer Descriptor for isoc OUT transfers will be retired with HWO=0. As a result, we won't return early. The req->remaining will be updated to include the BUFSIZ count of the extra TRB, and the actual number of transferred bytes calculation will be wrong. To fix this, check whether it's a short or zero packet and the last TRB chain bit to return early.

[PATCH] remoteproc: qcom: q6v5: Propagate EPROBE_DEFER

by Bjorn Andersson

In the case that the interrupts fail to result because of the interrupt-controller not yet being registered the platform_get_irq_byname() call will fail with -EPROBE_DEFER, but passing this into devm_request_threaded_irq() will result in -EINVAL being returned, the driver is therefor not reprobed later.

[PATCH v3] devres: Explicitly align datai[] to 64-bit

by Alexey Brodkin

data[] must be 64-bit aligned even on 32-bit architectures because it might be accessed by instructions that require aligned memory arguments. One example is "atomic64_t" type accessed by special atomic instructions which may read/write entire 64-bit word. Atomic instructions are a bit special compared to normal loads and stores. Even if normal loads and stores may deal with unaligned data, atomic instructions still require data to be aligned because it's hard to manage atomic value that spans through multiple cache lines or even MMU pages. And hardware just raises an alignment fault exception. The problem with previously used approach is that depending on ABI "long long" type of a particular 32-bit CPU might be aligned to 8-, 16-, 32- or 64-bit boundary. Which will get in the way of mentioned above atomic instructions. Consider the following snippet: | struct mystruct { | atomic64_t myvar; | } | | struct mystruct *p; | p = devm_kzalloc(dev, sizeof(*p), GFP_KERNEL); Here address of "myvar" will match data[] in "struct devres", that said if "data" is not 64-bit aligned atomic instruction will fail on the first access to "myvar".

[PATCH v2] mtd: rawnand: marvell: check for RDY bits after enabling the IRQ

by Daniel Mack

At least on PXA3xx platforms, enabling RDY interrupts in the NDCR register will only cause the IRQ to latch when the RDY lanes are changing, and not in case they are already asserted. This means that if the controller finished the command in flight before marvell_nfc_wait_op() is called, that function will wait for a change in the bit that can't ever happen as it is already set. To address this race, check for the RDY bits after the IRQ was enabled, and complete the completion immediately if the condition is already met. This fixes a bug that was observed with a NAND chip that holds a UBIFS parition on which file system stress tests were executed. When marvell_nfc_wait_op() reports an error, UBI/UBIFS will eventually mount the filesystem read-only, reporting lots of warnings along the way.

[PATCH] mtd: spi-nor: fsl-quadspi: Don't let -EINVAL on the bus

by Ahmad Fatoum

fsl_qspi_get_seqid() may return -EINVAL, but fsl_qspi_init_ahb_read() doesn't check for error codes with the result that -EINVAL could find itself signalled over the bus. In conjunction with the LS1046A SoC's A-009283 errata ("Illegal accesses to SPI flash memory can result in a system hang") this illegal access to SPI flash memory results in a system hang if userspace attempts reading later on. Avoid this by always checking fsl_qspi_get_seqid()'s return value and bail out otherwise.

Please apply "ext4: verify the depth of extent tree in ext4_find_extent()" to 3.18.y

by Greg Hackmann

bc890a602471 ("ext4: verify the depth of extent tree in ext4_find_extent()") fixes a potential buffer overrun when mounting corrupted ext4 filesystems. It was taken into 4.4.y and later but not 3.18.y, probably because it doesn't build as-is against 3.18. Ben Hutchings has a backport in the latest 3.16.y release (09999807edd8) which would work for 3.18.y too.

[PATCH v4.9.y] ext4: never move the system.data xattr out of the inode body

by Guenter Roeck

From: Theodore Ts'o <tytso(a)mit.edu> commit 8cdb5240ec5928b20490a2bb34cb87e9a5f40226 upstream. When expanding the extra isize space, we must never move the system.data xattr out of the inode body. For performance reasons, it doesn't make any sense, and the inline data implementation assumes that system.data xattr is never in the external xattr block.

[PATCH] firmware: Always initialize the fw_priv list object

When freeing the fw_priv the item is taken off the list. This causes an oops in the FW_OPT_NOCACHE case as the list object is not initialized.

[PATCH] kdb: print real address of pointers instead of hashed addresses

by Christophe Leroy

Since commit ad67b74d2469 ("printk: hash addresses printed with %p"), all pointers printed with %p are printed with hashed addresses instead of real addresses in order to avoid leaking addresses in dmesg and syslog. But this applies to kdb too, with is unfortunate: Entering kdb (current=0x(ptrval), pid 329) due to Keyboard Entry kdb> ps 15 sleeping system daemon (state M) processes suppressed, use 'ps A' to see all.

[RFT PATCH 1/2] xhci: Fix leaking USB3 shared_hcd at xhci removal

by Mathias Nyman

Ensure that the shared_hcd pointer is valid when calling usb_put_hcd() The shared_hcd is removed and freed in xhci by first calling usb_remove_hcd(xhci->shared_hcd), and later usb_put_hcd(xhci->shared_hcd) Afer commit fe190ed0d602 ("xhci: Do not halt the host until both HCD have disconnected their devices.") the shared_hcd was never properly put as xhci->shared_hcd was set to NULL before usb_put_hcd(xhci->shared_hcd) was called. shared_hcd (USB3) is removed before primary hcd (USB2). While removing the primary hcd we might need to handle xhci interrupts to cleanly remove last USB2 devices, therefore we need to set xhci->shared_hcd to NULL before removing the primary hcd to let xhci interrupt handler know shared_hcd is no longer available. xhci-plat.c, xhci-histb.c and xhci-mtk first create both their hcd's before adding them. so to keep the correct reverse removal order use a temporary shared_hcd variable for them. For more details see commit 4ac53087d6d4 ("usb: xhci: plat: Create both HCDs before adding them") Fixes: fe190ed0d602 ("xhci: Do not halt the host until both HCD have disconnected their devices.")

[PATCH stable v4.17] PCI: aardvark: Size bridges before resources allocation

by Thomas Petazzoni

From: Zachary Zhang <zhangzg(a)marvell.com> commit 91a2968e245d6ba616db37001fa1a043078b1a65 usptream. The PCIE I/O and MEM resource allocation mechanism is that root bus goes through the following steps: 1. Check PCI bridges' range and computes I/O and Mem base/limits. 2. Sort all subordinate devices I/O and MEM resource requirements and allocate the resources and writes/updates subordinate devices' requirements to PCI bridges I/O and Mem MEM/limits registers. Currently, PCI Aardvark driver only handles the second step and lacks the first step, so there is an I/O and MEM resource allocation failure when using a PCI switch. This commit fixes that by sizing bridges before doing the resource allocation.

patch "tools: hv: fcopy: set 'error' in case an unknown operation was" added to char-misc-linus

by gregkh＠linuxfoundation.org

This is a note to let you know that I've just added the patch titled tools: hv: fcopy: set 'error' in case an unknown operation was to my char-misc git tree which can be found at git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/char-misc.git in the char-misc-linus branch. The patch will show up in the next release of the linux-next tree (usually sometime within the next 24 hours during the week.) The patch will hopefully also be merged in Linus's tree for the next -rc kernel release. If you have any questions about this process, please let me know. >From c2d68afba86d1ff01e7300c68bc16a9234dcd8e9 Mon Sep 17 00:00:00 2001 From: Vitaly Kuznetsov <vkuznets(a)redhat.com> Date: Mon, 17 Sep 2018 04:14:55 +0000 Subject: tools: hv: fcopy: set 'error' in case an unknown operation was requested 'error' variable is left uninitialized in case we see an unknown operation.

Please apply 2c155709e4ef ("staging: android: ion: fix ION_IOC_{MAP,SHARE} use-after-free") to 3.18.y

by Greg Hackmann

2c155709e4ef ("staging: android: ion: fix ION_IOC_{MAP,SHARE} use-after-free") was applied to 4.4.y a couple of weeks ago, and is needed on 3.18.y too. The patch cherry-picks and builds as-is on top of 3.18.123.

[PATCH v4.4.y] ext4: never move the system.data xattr out of the inode body

by Zubin Mithra

From: Theodore Ts'o <tytso(a)mit.edu> commit 8cdb5240ec5928b20490a2bb34cb87e9a5f40226 upstream. When expanding the extra isize space, we must never move the system.data xattr out of the inode body. For performance reasons, it doesn't make any sense, and the inline data implementation assumes that system.data xattr is never in the external xattr block. This addresses CVE-2018-10880 https://bugzilla.kernel.org/show_bug.cgi?id=200005 Backport Note: - dfa2064b22("ext4: factor out loop for freeing inode xattr space") factored out the loop from inside ext4_expand_extra_isize_ea to a separate function named ext4_xattr_make_inode_space. As the above commit is not present in 4.4.y, make the change inside ext4_expand_extra_isize_ea.

This wait should be momentary. During a link down event, the cleanup handling does not ensure that all packets caught by the link down are flushed properly. This is caused by the fact that the freeze path and the link down event is handled the same. This is not correct. The freeze path waits until the HFI is unfrozen and then restarts PIO. A link down is not a freeze event. The link down path cannot restart the PIO until link is restored. If the PIO path is restarted before the link comes up, the application (QP) using the PIO path will hang (until link is restored). Fix by separating the linkdown path from the freeze path and use the link down path for link down events. Close a race condition sc_disable() by acquiring both the progress and release locks. Close a race condition in sc_stop() by moving the setting of the flag bits under the alloc lock.

This will cause the packet stream to block. HFI has 8 virtual lanes available for packet streams. Each lane can be enabled or disabled using the UnsupportedVL mask. If a lane is disabled, adding a packet to the send context must be disallowed. The current mask for determining unsupported VLs defaults to 0 (allow all). This is incorrect. Only the VLs that are defined should be allowed. Determine which VLs are disabled (mtu == 0), and set the appropriate unsupported bit in the mask. The correct mask will allow the send engine to error on the invalid VL, and error recovery will work correctly.

[PATCH] media: uvcvideo: Support UVC 1.5 video probe & commit controls

by Laurent Pinchart

From: ming_qian <ming_qian(a)realsil.com.cn> commit f620d1d7afc7db57ab59f35000752840c91f67e7 upstream. The length of UVC 1.5 video control is 48, and it is 34 for UVC 1.1.

This version fixes the conflicts and is otherwise not modified. The decision to mark the patch as a stable candidate came after reports from distro users that their UVC 1.5 camera was otherwise unusable. A guide has even been published to tell Debian users how to patch their kernel to fix the problem.

Currently the static fixmap setup in head_64.S only covers 2M virtual address space, while it actually could be in 4M space with different kernel configurations, e.g. when VSYSCALL emulation is disabled. So increase the static space to 4M for now by defining FIXMAP_PMD_NUM to 2, and add a build time check to ensure that the fixmap is covered by the initial static page tables.

Currently the static fixmap setup in head_64.S only covers 2M virtual address space, while it actually could be in 4M space with different kernel configurations, e.g. when VSYSCALL emulation is disabled. So increase the static space to 4M for now by defining FIXMAP_PMD_NUM to 2, and add a build time check to ensure that the fixmap is covered by the initial static page tables.

This is because we started using ktime to track elapsed time, and we convert nanoseconds to jiffies when we update the partition counter. However, this gets rounded down, so any I/Os that take less than a jiffy are not accounted for. Previously in this case, the value of jiffies would sometimes increment while we were doing I/O, so at least some I/Os were accounted for. Let's convert the stats to use nanoseconds internally. We still report milliseconds as before, now more accurately than ever. The value is still truncated to 32 bits for backwards compatibility.

[PATCH 1/2] iio: adc: at91: fix acking DRDY irq on simple conversions

by Eugen Hristev

When doing simple conversions, the driver did not acknowledge the DRDY irq. If this irq is not acked, it will be left pending, and as soon as a trigger is enabled, the irq handler will be called, it doesn't know why this irq has occurred because no channel is pending, and then we will have irq loop and board will hang.
