[Linux-stable-mirror] [PATCH] drbd: fix discard_zeroes_if_aligned regression

by Eric Wheeler

From: Eric Wheeler <git(a)linux.ewheeler.net> According to drbd.conf documentation, "To not break established and expected behaviour, and suddenly cause fstrim on thin-provisioned LVs to run out-of-space instead of freeing up space, the default value is yes." This behavior regressed in the REQ_OP_WRITE_ZEROES refactor near 45c21793 drbd: implement REQ_OP_WRITE_ZEROES 0dbed96 drbd: make intelligent use of blkdev_issue_zeroout which caused dm-thin backed DRBD volumes to zero blocks and run out of space instead of passing discard to the backing device as defined by the discard_zeroes_if_aligned option. A helper function could reduce code duplication.

[Linux-stable-mirror] [PATCH v2] usb: dwc3: core: Fix ULPI PHYs and prevent phy_get/ulpi_init during suspend/resume

by Roger Quadros

In order for ULPI PHYs to work, dwc3_phy_setup() and dwc3_ulpi_init() must be doene before dwc3_core_get_phy(). commit 541768b08a40 ("usb: dwc3: core: Call dwc3_core_get_phy() before initializing phys") broke this. The other issue is that dwc3_core_get_phy() and dwc3_ulpi_init() should be called only once during the life cycle of the driver. However, as dwc3_core_init() is called during system suspend/resume it will result in multiple calls to dwc3_core_get_phy() and dwc3_ulpi_init() which is wrong. Fix this by moving dwc3_ulpi_init() out of dwc3_phy_setup() into dwc3_core_ulpi_init(). Use a flag 'ulpi_ready' to ensure that dwc3_core_ulpi_init() is called only once from dwc3_core_init(). Use another flag 'phys_ready' to call dwc3_core_get_phy() only once from dwc3_core_init(). Fixes: 541768b08a40 ("usb: dwc3: core: Call dwc3_core_get_phy() before initializing phys") Fixes: f54edb539c11 ("usb: dwc3: core: initialize ULPI before trying to get the PHY") Cc: linux-stable <stable(a)vger.kernel.org> # >= v4.13 Signed-off-by: Roger Quadros <rogerq(a)ti.com> --- Changelog: v2: - don't break ULPI case.

Patch to consider for stable 3.18, 4.4 and 4.9

by Tomasz Kramkowski

In September last year, Ben Hutchings submitted commit [9547837bdccb] for 3.16.48-rc1 and I informed him that it would be useless without [3f3752705dbd] (and that maybe [c3883fe06488] would be useful as well). Ben dropped the patch but suggested I email this list with the information of the other two patches but I never quite got around to it. Now I see Sasha Levin is submitting [3f3752705dbd] and [c3883fe06488] for 4.9, 4.4 and 3.18 it would now make sense to include [9547837bdccb]. This patch fixes a minor problem where a certain USB adapter for Sega Genesis controllers appears as one input device when it has two ports for two controllers. I imagine some users of emulator distributions might use stable kernels and might benefit from this fix. I'm actually not entirely sure that patch is something suitable for stable but since it was already submitted once then I don't think it hurts to bring it up again (despite it breaking stable-kernel-rules as far as I understand it). Commits mentioned: [9547837bdccb]: HID: usbhid: add quirk for innomedia INNEX GENESIS/ATARI adapter [3f3752705dbd]: HID: reject input outside logical range only if null state is set [c3883fe06488]: HID: clamp input to logical range if no null state If the patch [9547837bdccb] is not relevant then feel free to ignore this email. Thanks, -- Tomasz Kramkowski

[PATCH] cdrom: Fix info leak/OOB read in cdrom_ioctl_drive_status

by Scott Bauer

Like d88b6d04: "cdrom: information leak in cdrom_ioctl_media_changed()" There is another cast from unsigned long to int which causes a bounds check to fail with specially crafted input. The value is then used as an index in the slot array in cdrom_slot_status().
