If dm-crypt uses authenticated mode with separate MAC, there are two concatenated part of the key structure - key(s) for encryption and authentication key. Add a missing check for authenticated key length. If this key length is smaller than actually provided key, dm-crypt now properly fails instead of crashing.

[Linux-stable-mirror] Patch "ARM: dts: kirkwood: fix pin-muxing of MPP7 on OpenBlocks A7" has been added to the 4.14-stable tree

by gregkh＠linuxfoundation.org

This is a note to let you know that I've just added the patch titled ARM: dts: kirkwood: fix pin-muxing of MPP7 on OpenBlocks A7 to the 4.14-stable tree which can be found at: http://www.kernel.org/git/?p=linux/kernel/git/stable/stable-queue.git;a=sum… The filename of the patch is: arm-dts-kirkwood-fix-pin-muxing-of-mpp7-on-openblocks-a7.patch and it can be found in the queue-4.14 subdirectory. If you, or anyone else, feels it should not be added to the stable tree, please let <stable(a)vger.kernel.org> know about it. >From 56aeb07c914a616ab84357d34f8414a69b140cdf Mon Sep 17 00:00:00 2001 From: Thomas Petazzoni <thomas.petazzoni(a)free-electrons.com> Date: Thu, 4 Jan 2018 17:53:12 +0100 Subject: ARM: dts: kirkwood: fix pin-muxing of MPP7 on OpenBlocks A7 From: Thomas Petazzoni <thomas.petazzoni(a)free-electrons.com> commit 56aeb07c914a616ab84357d34f8414a69b140cdf upstream. MPP7 is currently muxed as "gpio", but this function doesn't exist for MPP7, only "gpo" is available. This causes the following error: kirkwood-pinctrl f1010000.pin-controller: unsupported function gpio on pin mpp7 pinctrl core: failed to register map default (6): invalid type given kirkwood-pinctrl f1010000.pin-controller: error claiming hogs: -22 kirkwood-pinctrl f1010000.pin-controller: could not claim hogs: -22 kirkwood-pinctrl f1010000.pin-controller: unable to register pinctrl driver kirkwood-pinctrl: probe of f1010000.pin-controller failed with error -22 So the pinctrl driver is not probed, all device drivers (including the UART driver) do a -EPROBE_DEFER, and therefore the system doesn't really boot (well, it boots, but with no UART, and no devices that require pin-muxing). Back when the Device Tree file for this board was introduced, the definition was already wrong. The pinctrl driver also always described as "gpo" this function for MPP7. However, between Linux 4.10 and 4.11, a hog pin failing to be muxed was turned from a simple warning to a hard error that caused the entire pinctrl driver probe to bail out. This is probably the result of commit 6118714275f0a ("pinctrl: core: Fix pinctrl_register_and_init() with pinctrl_enable()"). This commit fixes the Device Tree to use the proper "gpo" function for MPP7, which fixes the boot of OpenBlocks A7, which was broken since Linux 4.11.

[Linux-stable-mirror] Patch "phy: work around 'phys' references to usb-nop-xceiv devices" has been added to the 3.18-stable tree

by gregkh＠linuxfoundation.org

This is a note to let you know that I've just added the patch titled phy: work around 'phys' references to usb-nop-xceiv devices to the 3.18-stable tree which can be found at: http://www.kernel.org/git/?p=linux/kernel/git/stable/stable-queue.git;a=sum… The filename of the patch is: phy-work-around-phys-references-to-usb-nop-xceiv-devices.patch and it can be found in the queue-3.18 subdirectory. If you, or anyone else, feels it should not be added to the stable tree, please let <stable(a)vger.kernel.org> know about it. >From b7563e2796f8b23c98afcfea7363194227fa089d Mon Sep 17 00:00:00 2001 From: Arnd Bergmann <arnd(a)arndb.de> Date: Fri, 12 Jan 2018 11:12:05 +0100 Subject: phy: work around 'phys' references to usb-nop-xceiv devices From: Arnd Bergmann <arnd(a)arndb.de> commit b7563e2796f8b23c98afcfea7363194227fa089d upstream. Stefan Wahren reports a problem with a warning fix that was merged for v4.15: we had lots of device nodes with a 'phys' property pointing to a device node that is not compliant with the binding documented in Documentation/devicetree/bindings/phy/phy-bindings.txt This generally works because USB HCD drivers that support both the generic phy subsystem and the older usb-phy subsystem ignore most errors from phy_get() and related calls and then use the usb-phy driver instead. However, it turns out that making the usb-nop-xceiv device compatible with the generic-phy binding changes the phy_get() return code from -EINVAL to -EPROBE_DEFER, and the dwc2 usb controller driver for bcm2835 now returns -EPROBE_DEFER from its probe function rather than ignoring the failure, breaking all USB support on raspberry-pi when CONFIG_GENERIC_PHY is enabled. The same code is used in the dwc3 driver and the usb_add_hcd() function, so a reasonable assumption would be that many other platforms are affected as well. I have reviewed all the related patches and concluded that "usb-nop-xceiv" is the only USB phy that is affected by the change, and since it is by far the most commonly referenced phy, all the other USB phy drivers appear to be used in ways that are are either safe in DT (they don't use the 'phys' property), or in the driver (they already ignore -EPROBE_DEFER from generic-phy when usb-phy is available). To work around the problem, this adds a special case to _of_phy_get() so we ignore any PHY node that is compatible with "usb-nop-xceiv", as we know that this can never load no matter how much we defer. In the future, we might implement a generic-phy driver for "usb-nop-xceiv" and then remove this workaround. Since we generally want older kernels to also want to work with the fixed devicetree files, it would be good to backport the patch into stable kernels as well (3.13+ are possibly affected), even though they don't contain any of the patches that may have caused regressions.

Nikolaus Schaller <hns(a)goldelico.com> commit c52c545ead97fcc2f4f8ea38f1ae3c23211e09a8 upstream. commit e7ec014a47e4 ("Input: twl6040-vibra - update for device tree support") made the separate vibra DT node to a subnode of the twl6040. It now calls of_find_node_by_name() to locate the "vibra" subnode. This function has a side effect to call of_node_put on() for the twl6040 parent node passed in as a parameter. This causes trouble later on. Solution: we must call of_node_get() before of_find_node_by_name() Signed-off-by: H.

Fix child-node lookup during probe, which ended up searching the whole device tree depth-first starting at parent rather than just matching on its children. Later sanity checks on node properties (which would likely be missing) should prevent this from causing much trouble however, especially as the original premature free of the parent node has already been fixed separately (but that "fix" was apparently never backported to stable).
