[Linux-stable-mirror] Patch "usb: dwc2: Improve gadget state disconnection handling" has been added to the 4.14-stable tree

This is a note to let you know that I've just added the patch titled usb: dwc2: Improve gadget state disconnection handling 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: usb-dwc2-improve-gadget-state-disconnection-handling.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 d2471d4a24dfbff5e463d382e2c6fec7d7e25a09 Mon Sep 17 00:00:00 2001 From: John Stultz <john.stultz(a)linaro.org> Date: Mon, 23 Oct 2017 14:32:48 -0700 Subject: usb: dwc2: Improve gadget state disconnection handling From: John Stultz <john.stultz(a)linaro.org> commit d2471d4a24dfbff5e463d382e2c6fec7d7e25a09 upstream. In the earlier commit dad3f793f20f ("usb: dwc2: Make sure we disconnect the gadget state"), I was trying to fix up the fact that we somehow weren't disconnecting the gadget state, so that when the OTG port was plugged in the second time we would get warnings about the state tracking being wrong. (This seems to be due to a quirk of the HiKey board where we do not ever get any otg interrupts, particularly the session end detected signal. Instead we only see status change interrupt.) The fix there was somewhat simple, as it just made sure to call dwc2_hsotg_disconnect() before we connected things up in OTG mode, ensuring the state handling didn't throw errors. But in looking at a different issue I was seeing with UDC state handling, I realized that it would be much better to call dwc2_hsotg_disconnect when we get the state change signal moving to host mode. Thus, this patch removes the earlier disconnect call I added and moves it (and the needed locking) to the host mode transition.

[Linux-stable-mirror] [PATCH] acpi, nfit: fix health event notification

by Dan Williams

Integration testing with a BIOS that generates injected health event notifications fails to communicate those events to userspace. The nfit driver neglects to link the ACPI DIMM device with the necessary driver data so acpi_nvdimm_notify() fails this lookup: nfit_mem = dev_get_drvdata(dev); if (nfit_mem && nfit_mem->flags_attr) sysfs_notify_dirent(nfit_mem->flags_attr); Add the necessary linkage when installing the notification handler and clean it up when the nfit driver instance is torn down.

[Linux-stable-mirror] [PATCH] KEYS: reject NULL restriction string when type is specified

by Eric Biggers

From: Eric Biggers <ebiggers(a)google.com> keyctl_restrict_keyring() allows through a NULL restriction when the "type" is non-NULL, which causes a NULL pointer dereference in asymmetric_lookup_restriction() when it calls strcmp() on the restriction string. But no key types actually use a "NULL restriction" to mean anything, so update keyctl_restrict_keyring() to reject it with EINVAL.

[Linux-stable-mirror] patch "usb: xhci: fix TDS for MTK xHCI1.1" added to usb-linus

by gregkh＠linuxfoundation.org

This is a note to let you know that I've just added the patch titled usb: xhci: fix TDS for MTK xHCI1.1 to my usb git tree which can be found at git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/usb.git in the usb-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 72b663a99c074a8d073e7ecdae446cfb024ef551 Mon Sep 17 00:00:00 2001 From: Chunfeng Yun <chunfeng.yun(a)mediatek.com> Date: Fri, 8 Dec 2017 18:10:06 +0200 Subject: usb: xhci: fix TDS for MTK xHCI1.1 For MTK's xHCI 1.0 or latter, TD size is the number of max packet sized packets remaining in the TD, not including this TRB (following spec).
