+
+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: gfs2: Fix filesystem block deallocation for short writes
+
+From: Andreas Gruenbacher <agruenba@redhat.com>
+
+[ Upstream commit d031a8866e709c9d1ee5537a321b6192b4d2dc5b ]
+
+When a write cannot be carried out in full, gfs2_iomap_end() releases
+blocks that have been allocated for this write but haven't been used.
+
+To compute the end of the allocation, gfs2_iomap_end() incorrectly
+rounded the end of the attempted write down to the next block boundary
+to arrive at the end of the allocation. It would have to round up, but
+the end of the allocation is also available as iomap->offset +
+iomap->length, so just use that instead.
+
+In addition, use round_up() for computing the start of the unused range.

+Subject: net/sched: act_pedit: really ensure the skb is writable
+
+From: Paolo Abeni <pabeni@redhat.com>
+
+[ Upstream commit 8b796475fd7882663a870456466a4fb315cc1bd6 ]
+
+Currently pedit tries to ensure that the accessed skb offset
+is writable via skb_unclone(). The action potentially allows
+touching any skb bytes, so it may end-up modifying shared data.
+
+The above causes some sporadic MPTCP self-test failures, due to
+this code:
+
+ tc -n $ns2 filter add dev ns2eth$i egress \
+ protocol ip prio 1000 \
+ handle 42 fw \
+ action pedit munge offset 148 u8 invert \
+ pipe csum tcp \
+ index 100
+
+The above modifies a data byte outside the skb head and the skb is
+a cloned one, carrying a TCP output packet.
+
+This change addresses the issue by keeping track of a rough
+over-estimate highest skb offset accessed by the action and ensuring
+such offset is really writable.
+
+Note that this may cause performance regressions in some scenarios,
+but hopefully pedit is not in the critical path.

+
+[ 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().

+Subject: s390: disable -Warray-bounds
+
+From: Sven Schnelle <svens@linux.ibm.com>
+
+[ Upstream commit 8b202ee218395319aec1ef44f72043e1fbaccdd6 ]
+
+gcc-12 shows a lot of array bound warnings on s390. This is caused
+by the S390_lowcore macro which uses a hardcoded address of 0.
+
+Wrapping that with absolute_pointer() works, but gcc no longer knows
+that a 12 bit displacement is sufficient to access lowcore. So it
+emits instructions like 'lghi %r1,0; l %rx,xxx(%r1)' instead of a
+single load/store instruction. As s390 stores variables often
+read/written in lowcore, this is considered problematic. Therefore
+disable -Warray-bounds on s390 for gcc-12 for the time being, until
+there is a better solution.

+
+In order to limit the ability for an observer to recognize the source
+ports sequence used to contact a set of destinations, we should
+periodically shuffle the secret. 10 seconds looks effective enough
+without causing particular issues.
