+
+From: Mark Brown <broonie@kernel.org>
+
+[ Upstream commit 13fcf676d9e102594effc686d98521ff5c90b925 ]
+
+The max98090 driver has some custom controls which share a put() function
+which returns 0 unconditionally, meaning that events are not generated
+when the value changes. Fix that.

+
+From: Mark Brown <broonie@kernel.org>
+
+[ Upstream commit 2fbe467bcbfc760a08f08475eea6bbd4c2874319 ]
+
+The max98090 driver has a custom put function for some controls which can
+only be updated in certain circumstances which makes no effort to validate
+that input is suitable for the control, allowing out of spec values to be
+written to the hardware and presented to userspace. Fix this by returning
+an error when invalid values are written.

+Subject: batman-adv: Don't skb_split skbuffs with frag_list
+
+From: Sven Eckelmann <sven@narfation.org>
+
+[ Upstream commit a063f2fba3fa633a599253b62561051ac185fa99 ]
+
+The receiving interface might have used GRO to receive more fragments than
+MAX_SKB_FRAGS fragments. In this case, these will not be stored in
+skb_shinfo(skb)->frags but merged into the frag list.
+
+batman-adv relies on the function skb_split to split packets up into
+multiple smaller packets which are not larger than the MTU on the outgoing
+interface. But this function cannot handle frag_list entries and is only
+operating on skb_shinfo(skb)->frags. If it is still trying to split such an
+skb and xmit'ing it on an interface without support for NETIF_F_FRAGLIST,
+then validate_xmit_skb() will try to linearize it. But this fails due to
+inconsistent information. And __pskb_pull_tail will trigger a BUG_ON after
+skb_copy_bits() returns an error.
+
+In case of entries in frag_list, just linearize the skb before operating on
+it with skb_split().

+Subject: net: sfc: ef10: fix memory leak in efx_ef10_mtd_probe()
+
+From: Taehee Yoo <ap420073@gmail.com>
+
+[ Upstream commit 1fa89ffbc04545b7582518e57f4b63e2a062870f ]
+
+In the NIC ->probe() callback, ->mtd_probe() callback is called.
+If NIC has 2 ports, ->probe() is called twice and ->mtd_probe() too.
+In the ->mtd_probe(), which is efx_ef10_mtd_probe() it allocates and
+initializes mtd partiion.
+But mtd partition for sfc is shared data.
+So that allocated mtd partition data from last called
+efx_ef10_mtd_probe() will not be used.
+Therefore it must be freed.
+But it doesn't free a not used mtd partition data in efx_ef10_mtd_probe().
+
+kmemleak reports:

+
+[ Upstream commit f3c46e41b32b6266cf60b0985c61748f53bf1c61 ]
+
+Non blocking sendmsg will return -EAGAIN when any signal pending
+and no send space left, while non blocking recvmsg return -EINTR
+when signal pending and no data received. This may makes confused.
+As TCP returns -EAGAIN in the conditions described above. Align the

+
+From: Eric Dumazet <edumazet@google.com>
+
+[ Upstream commit d5076fe4049cadef1f040eda4aaa001bb5424225 ]
+
+netlink_recvmsg() does not need to change transport header.
+
+If transport header was needed, it should have been reset
+by the producer (netlink_dump()), not the consumer(s).
+
+The following trace probably happened when multiple threads
+were using MSG_PEEK.
