Hello, I'm requesting this commit to be back-ported to v4.14: --- commit 5b18f1289808fee5d04a7e6ecf200189f41a4db6 Author: Stephen Suryaputra <ssuryaextr(a)gmail.com> Date: Wed Jun 26 02:21:16 2019 -0400 ipv4: reset rt_iif for recirculated mcast/bcast out pkts Multicast or broadcast egress packets have rt_iif set to the oif. These packets might be recirculated back as input and lookup to the raw sockets may fail because they are bound to the incoming interface (skb_iif). If rt_iif is not zero, during the lookup, inet_iif() function returns rt_iif instead of skb_iif. Hence, the lookup fails. v2: Make it non vrf specific (David Ahern). Reword the changelog to reflect it. Signed-off-by: Stephen Suryaputra <ssuryaextr(a)gmail.com> Reviewed-by: David Ahern <dsahern(a)gmail.com> Signed-off-by: David S.

[PATCH AUTOSEL 4.20 001/117] netfilter: ipset: Allow matching on destination MAC address for mac and ipmac sets

[PATCH 1/5] drm/i915/userptr: Beware recursive lock_page()

by Chris Wilson

Following a try_to_unmap() we may want to remove the userptr and so call put_pages(). However, try_to_unmap() acquires the page lock and so we must avoid recursively locking the pages ourselves -- which means that we cannot safely acquire the lock around set_page_dirty(). Since we can't be sure of the lock, we have to risk skip dirtying the page, or else risk calling set_page_dirty() without a lock and so risk fs corruption.

[PATCH 2/2] DTS: ARM: gta04: introduce legacy spi-cs-high to make display work again

by H. Nikolaus Schaller

commit 6953c57ab172 "gpio: of: Handle SPI chipselect legacy bindings" did introduce logic to centrally handle the legacy spi-cs-high property in combination with cs-gpios. This assumes that the polarity of the CS has to be inverted if spi-cs-high is missing, even and especially if non-legacy GPIO_ACTIVE_HIGH is specified. The DTS for the GTA04 was orginally introduced under the assumption that there is no need for spi-cs-high if the gpio is defined with proper polarity GPIO_ACTIVE_HIGH. This was not a problem until gpiolib changed the interpretation of GPIO_ACTIVE_HIGH and missing spi-cs-high. The effect is that the missing spi-cs-high is now interpreted as CS being low (despite GPIO_ACTIVE_HIGH) which turns off the SPI interface when the panel is to be programmed by the panel driver. Therefore, we have to add the redundant and legacy spi-cs-high property to properly pass through the legacy handler. Since this is nowhere documented in the bindings, we add some words of WARNING.

[PATCH stable 3.15 to 3.18] staging: comedi: dt282x: fix a null pointer deref on interrupt

by Ian Abbott

commit b8336be66dec06bef518030a0df9847122053ec5 upstream. The interrupt handler `dt282x_interrupt()` causes a null pointer dereference for those supported boards that have no analog output support. For these boards, `dev->write_subdev` will be `NULL` and therefore the `s_ao` subdevice pointer variable will be `NULL`. In that case, the following call near the end of the interrupt handler results in a null pointer dereference: cfc_handle_events(dev, s_ao); [ Upstream equivalent: comedi_handle_events(dev, s_ao); -- IA ] Fix it by only calling the above function if `s_ao` is valid. (There are other uses of `s_ao` by the interrupt handler that may or may not be reached depending on values of hardware registers. Trust that they are reliable for now.)

[PATCH] ath10k: Fix HOST capability QMI incompatibility

by Bjorn Andersson

The introduction of 768ec4c012ac ("ath10k: update HOST capability QMI message") served the purpose of supporting the new and extended HOST capability QMI message. But while the new message adds a slew of optional members it changes the data type of the "daemon_support" member, which means that older versions of the firmware will fail to decode the incoming request message. There is no way to detect this breakage from Linux and there's no way to recover from sending the wrong message (i.e. we can't just try one format and then fallback to the other), so a quirk is introduced in DeviceTree to indicate to the driver that the firmware requires the 8bit version of this message.
