#1558346 — [PATCH 4.9 41/59] tools/virtio: fix READ_ONCE()

4.9-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Mark Rutland <mark.rutland@arm.com>

commit 5da889c795b1fbefc9d8f058b54717ab8ab17891 upstream.

The virtio tools implementation of READ_ONCE() has a single parameter called
'var', but erroneously refers to 'val' for its cast, and thus won't work unless
there's a variable of the correct type that happens to be called 'var'.

Fix this with s/var/val/, making READ_ONCE() work as expected regardless.

#1558347 — [PATCH 4.9 49/59] bus: arm-ccn: Prevent hotplug callback leak

4.9-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Thomas Gleixner <tglx@linutronix.de>

commit 26242b330093fd14c2e94fb6cbdf0f482ab26576 upstream.

In case the driver registration fails, the hotplug callback is leaked.

Not fatal, because it's never invoked as there are no instances registered,
but wrong nevertheless.

4.9-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Xin Long <lucien.xin@gmail.com>


[ Upstream commit 08abb79542c9e8c367d1d8e44fe1026868d3f0a7 ]

Prior to this patch, sctp_transport_lookup_process didn't rcu_read_unlock
when it failed to find a transport by sctp_addrs_lookup_transport.

This patch is to fix it by moving up rcu_read_unlock right before checking
transport and also to remove the out path.

#1558353 — [PATCH 4.9 40/59] powerpc: Fix build warning on 32-bit PPC

4.9-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Larry Finger <Larry.Finger@lwfinger.net>

commit 8ae679c4bc2ea2d16d92620da8e3e9332fa4039f upstream.

I am getting the following warning when I build kernel 4.9-git on my
PowerBook G4 with a 32-bit PPC processor:

    AS      arch/powerpc/kernel/misc_32.o
  arch/powerpc/kernel/misc_32.S:299:7: warning: "CONFIG_FSL_BOOKE" is not defined [-Wundef]

This problem is evident after commit 989cea5c14be ("kbuild: prevent
lib-ksyms.o rebuilds"); however, this change in kbuild only exposes an
error that has been in the code since 2005 when this source file was
created.  That was with commit 9994a33865f4 ("powerpc: Introduce
entry_{32,64}.S, misc_{32,64}.S, systbl.S").

The offending line does not make a lot of sense.  This error does not
seem to cause any errors in the executable, thus I am not recommending
that it be applied to any stable versions.

Thanks to Nicholas Piggin for suggesting this solution.

#1558354 — [PATCH 4.9 18/59] net: ipv4: dst for local input routes should use l3mdev if relevant

4.9-stable review patch.  If anyone has any objections, please let me know.

------------------

From: David Ahern <dsa@cumulusnetworks.com>


[ Upstream commit f5a0aab84b74de68523599817569c057c7ac1622 ]

IPv4 output routes already use l3mdev device instead of loopback for dst's
if it is applicable. Change local input routes to do the same.

This fixes icmp responses for unreachable UDP ports which are directed
to the wrong table after commit 9d1a6c4ea43e4 because local_input
routes use the loopback device. Moving from ingress device to loopback
loses the L3 domain causing responses based on the dst to get to lost.

Fixes: 9d1a6c4ea43e4 ("net: icmp_route_lookup should use rt dev to
		       determine L3 domain")

------------------

From: Robert Jarzmik <robert.jarzmik@free.fr>

commit e413bd33ac44b6d0bebc0ef2ac19cbe7558a7303 upstream.

accessed through the 6th coprocessor, contrary to pxa27x and pxa3xx
architectures.

Fix it to behave as in non-devicetree builds.

#1558359 — [PATCH 4.9 34/59] gro: Disable frag0 optimization on IPv6 ext headers

4.9-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Herbert Xu <herbert@gondor.apana.org.au>


[ Upstream commit 57ea52a865144aedbcd619ee0081155e658b6f7d ]

The GRO fast path caches the frag0 address.  This address becomes
invalid if frag0 is modified by pskb_may_pull or its variants.
So whenever that happens we must disable the frag0 optimization.

This is usually done through the combination of gro_header_hard
and gro_header_slow, however, the IPv6 extension header path did
the pulling directly and would continue to use the GRO fast path
incorrectly.

This patch fixes it by disabling the fast path when we enter the
IPv6 extension header path.

4.9-stable review patch.  If anyone has any objections, please let me know.

From: Saeed Mahameed <saeedm@mellanox.com>


[ Upstream commit 610e89e05c3f28a7394935aa6b91f99548c4fd3c ]

Skip setting netdev vxlan ports and netdev rx_mode on driver load
when netdev is not yet registered.

Synchronizing with netdev state is needed only on reset flow where the
netdev remains registered for the whole reset period.

This also fixes an access before initialization of net_device.addr_list_lock
- which for some reason initialized on register_netdev - where we queued
set_rx_mode work on driver load before netdev registration.

selection is bypassed. Use the FLOWI_FLAG_SKIP_NH_OIF to skip the oif
check similar to what is done in fib_table_lookup.

#1558368 — [PATCH 4.9 43/59] ARM64: dts: bcm2837-rpi-3-b: remove incorrect pwr LED

4.9-stable review patch.  If anyone has any objections, please let me know.

From: Andrea Merello <andrea.merello@gmail.com>

commit a44e87b47148c6ee6b78509f47e6a15c0fae890a upstream.

We are incorrectly defining the pwr LED, attaching it to a gpio line
that is wired to the Wi-Fi SDIO module (which fails due to this).

The actual power LED is connected to the GPIO expander, which we don't
expose currently.
