+Subject: Bluetooth: btusb: Add debug message for CSR controllers
+
+From: Ismael Ferreras Morezuelas <swyterzone@gmail.com>
+
+commit 955aebd445e2b49622f2184b7abb82b05c060549 upstream.
+
+The rationale of showing this is that it's potentially critical
+information to diagnose and find more CSR compatibility bugs in the
+future and it will save a lot of headaches.
+
+Given that clones come from a wide array of vendors (some are actually
+Barrot, some are something else) and these numbers are what let us find
+differences between actual and fake ones, it will be immensely helpful
+to scour the Internet looking for this pattern and building an actual
+database to find correlations and improve the checks.

+
+From: Rob Clark <robdclark@chromium.org>
+
+commit 09bf649a74573cb596e211418a4f8008f265c5a9 upstream.
+
+vm_open() is not allowed to fail. Fortunately we are guaranteed that
+the pages are already pinned, thanks to the initial mmap which is now
+being cloned into a forked process, and only need to increment the
+refcnt. So just increment it directly. Previously if a signal was
+delivered at the wrong time to the forking process, the
+mutex_lock_interruptible() could fail resulting in the pages_use_count
+not being incremented.

+Subject: drm/vmwgfx: Don't use screen objects when SEV is active
+
+From: Zack Rusin <zackr@vmware.com>
+
+commit 6e90293618ed476d6b11f82ce724efbb9e9a071b upstream.
+
+When SEV is enabled gmr's and mob's are explicitly disabled because
+the encrypted system memory can not be used by the hypervisor.
+
+The driver was disabling GMR's but the presentation code, which depends
+on GMR's, wasn't honoring it which lead to black screen on hosts
+with SEV enabled.
+
+Make sure screen objects presentation is not used when guest memory
+regions have been disabled to fix presentation on SEV enabled hosts.

+Subject: HID: ite: Enable QUIRK_TOUCHPAD_ON_OFF_REPORT on Acer Aspire Switch V 10
+
+From: Hans de Goede <hdegoede@redhat.com>
+
+commit 9ad6645a9dce4d0e42daca6ebf32a154401c59d3 upstream.
+
+The Acer Aspire Switch V 10 (SW5-017)'s keyboard-dock uses the same
+ITE controller setup as other Acer Switch 2-in-1's.
+
+This needs special handling for the wifi on/off toggle hotkey as well as
+to properly report touchpad on/off keypresses.
+
+Add the USB-ids for the SW5-017's keyboard-dock with a quirk setting of
+QUIRK_TOUCHPAD_ON_OFF_REPORT to fix both issues.

+Subject: KVM: s390: vsie: Fix the initialization of the epoch extension (epdx) field
+
+From: Thomas Huth <thuth@redhat.com>
+
+commit 0dd4cdccdab3d74bd86b868768a7dca216bcce7e upstream.
+
+We recently experienced some weird huge time jumps in nested guests when
+rebooting them in certain cases. After adding some debug code to the epoch
+handling in vsie.c (thanks to David Hildenbrand for the idea!), it was
+obvious that the "epdx" field (the multi-epoch extension) did not get set
+to 0xff in case the "epoch" field was negative.
+Seems like the code misses to copy the value from the epdx field from
+the guest to the shadow control block. By doing so, the weird time
+jumps are gone in our scenarios.

+Subject: media: v4l2-dv-timings.c: fix too strict blanking sanity checks
+
+From: Hans Verkuil <hverkuil-cisco@xs4all.nl>
+
+commit 5eef2141776da02772c44ec406d6871a790761ee upstream.
+
+Sanity checks were added to verify the v4l2_bt_timings blanking fields
+in order to avoid integer overflows when userspace passes weird values.
+
+But that assumed that userspace would correctly fill in the front porch,
+backporch and sync values, but sometimes all you know is the total
+blanking, which is then assigned to just one of these fields.
+
+And that can fail with these checks.
+
+So instead set a maximum for the total horizontal and vertical
+blanking and check that each field remains below that.
+
+That is still sufficient to avoid integer overflows, but it also
+allows for more flexibility in how userspace fills in these fields.

+Subject: memcg: fix possible use-after-free in memcg_write_event_control()
+
+From: Tejun Heo <tj@kernel.org>
+
+commit 4a7ba45b1a435e7097ca0f79a847d0949d0eb088 upstream.
+
+memcg_write_event_control() accesses the dentry->d_name of the specified
+control fd to route the write call. As a cgroup interface file can't be
+renamed, it's safe to access d_name as long as the specified file is a
+regular cgroup file. Also, as these cgroup interface files can't be
+removed before the directory, it's safe to access the parent too.
+
+Prior to 347c4a874710 ("memcg: remove cgroup_event->cft"), there was a
+call to __file_cft() which verified that the specified file is a regular
+cgroupfs file before further accesses. The cftype pointer returned from
+__file_cft() was no longer necessary and the commit inadvertently dropped
+the file type check with it allowing any file to slip through. With the
+invarients broken, the d_name and parent accesses can now race against
+renames and removals of arbitrary files and cause use-after-free's.
+
+Fix the bug by resurrecting the file type check in __file_cft(). Now that
+cgroupfs is implemented through kernfs, checking the file operations needs
+to go through a layer of indirection. Instead, let's check the superblock
+and dentry type.

+
+For dax pud, pud_huge() returns true on x86. So the function works as long

+Commit 414fd080d125 ("mm/gup: fix gup_pmd_range() for dax") fixed
+devmap-backed huge PMDs, but missed devmap-backed huge PUDs. Fix this as
+well.

+
+From: Radu Nicolae Pirea (OSS) <radu-nicolae.pirea@oss.nxp.com>
+
+commit f8bac7f9fdb0017b32157957ffffd490f95faa07 upstream.
+
+The SJA1105 family has 45 L2 policing table entries
+(SJA1105_MAX_L2_POLICING_COUNT) and SJA1110 has 110
+(SJA1110_MAX_L2_POLICING_COUNT). Keeping the table structure but
+accounting for the difference in port count (5 in SJA1105 vs 10 in
+SJA1110) does not fully explain the difference. Rather, the SJA1110 also
+has L2 ingress policers for multicast traffic. If a packet is classified
+as multicast, it will be processed by the policer index 99 + SRCPORT.
+
+The sja1105_init_l2_policing() function initializes all L2 policers such
+that they don't interfere with normal packet reception by default. To have
+a common code between SJA1105 and SJA1110, the index of the multicast
+policer for the port is calculated because it's an index that is out of
+bounds for SJA1105 but in bounds for SJA1110, and a bounds check is
+performed.
+
+The code fails to do the proper thing when determining what to do with the
+multicast policer of port 0 on SJA1105 (ds->num_ports = 5). The "mcast"
+index will be equal to 45, which is also equal to
+table->ops->max_entry_count (SJA1105_MAX_L2_POLICING_COUNT). So it passes
+through the check. But at the same time, SJA1105 doesn't have multicast
+policers. So the code programs the SHARINDX field of an out-of-bounds
+element in the L2 Policing table of the static config.
+
+The comparison between index 45 and 45 entries should have determined the
+code to not access this policer index on SJA1105, since its memory wasn't
+even allocated.
+
+With enough bad luck, the out-of-bounds write could even overwrite other
+valid kernel data, but in this case, the issue was detected using KASAN.

+Subject: net: mana: Fix race on per-CQ variable napi work_done
+
+From: Haiyang Zhang <haiyangz@microsoft.com>
+
+commit 18010ff776fa42340efc428b3ea6d19b3e7c7b21 upstream.
+
+After calling napi_complete_done(), the NAPIF_STATE_SCHED bit may be
+cleared, and another CPU can start napi thread and access per-CQ variable,
+cq->work_done. If the other thread (for example, from busy_poll) sets
+it to a value >= budget, this thread will continue to run when it should
+stop, and cause memory corruption and panic.
+
+To fix this issue, save the per-CQ work_done variable in a local variable
+before napi_complete_done(), so it won't be corrupted by a possible
+concurrent thread after napi_complete_done().
+
+Also, add a flag bit to advertise to the NIC firmware: the NAPI work_done
+variable race is fixed, so the driver is able to reliably support features
+like busy_poll.

+Subject: Revert "ARM: dts: imx7: Fix NAND controller size-cells"
+
+From: Francesco Dolcini <francesco.dolcini@toradex.com>
+
+commit ef19964da8a668c683f1d38274f6fb756e047945 upstream.
+
+This reverts commit 753395ea1e45c724150070b5785900b6a44bd5fb.
+
+It introduced a boot regression on colibri-imx7, and potentially any
+other i.MX7 boards with MTD partition list generated into the fdt by
+U-Boot.
+
+While the commit we are reverting here is not obviously wrong, it fixes
+only a dt binding checker warning that is non-functional, while it
+introduces a boot regression and there is no obvious fix ready.
