+Subject: iio: dac: cio-dac: Fix max DAC write value check for 12-bit
+
+From: William Breathitt Gray <william.gray@linaro.org>
+
+commit c3701185ee1973845db088d8b0fc443397ab0eb2 upstream.
+
+The CIO-DAC series of devices only supports DAC values up to 12-bit
+rather than 16-bit. Trying to write a 16-bit value results in only the
+lower 12 bits affecting the DAC output which is not what the user
+expects. Instead, adjust the DAC write value check to reject values
+larger than 12-bit so that they fail explicitly as invalid for the user.

+Subject: nilfs2: fix potential UAF of struct nilfs_sc_info in nilfs_segctor_thread()
+
+From: Ryusuke Konishi <konishi.ryusuke@gmail.com>
+
+commit 6be49d100c22ffea3287a4b19d7639d259888e33 upstream.
+
+The finalization of nilfs_segctor_thread() can race with
+nilfs_segctor_kill_thread() which terminates that thread, potentially
+causing a use-after-free BUG as KASAN detected.
+
+At the end of nilfs_segctor_thread(), it assigns NULL to "sc_task" member
+of "struct nilfs_sc_info" to indicate the thread has finished, and then
+notifies nilfs_segctor_kill_thread() of this using waitqueue
+"sc_wait_task" on the struct nilfs_sc_info.
+
+However, here, immediately after the NULL assignment to "sc_task", it is
+possible that nilfs_segctor_kill_thread() will detect it and return to
+continue the deallocation, freeing the nilfs_sc_info structure before the
+thread does the notification.
+
+This fixes the issue by protecting the NULL assignment to "sc_task" and
+its notification, with spinlock "sc_state_lock" of the struct
+nilfs_sc_info. Since nilfs_segctor_kill_thread() does a final check to
+see if "sc_task" is NULL with "sc_state_lock" locked, this can eliminate
+the race.

+Subject: nilfs2: fix sysfs interface lifetime
+
+From: Ryusuke Konishi <konishi.ryusuke@gmail.com>
+
+commit 42560f9c92cc43dce75dbf06cc0d840dced39b12 upstream.
+
+The current nilfs2 sysfs support has issues with the timing of creation
+and deletion of sysfs entries, potentially leading to null pointer
+dereferences, use-after-free, and lockdep warnings.
+
+Some of the sysfs attributes for nilfs2 per-filesystem instance refer to
+metadata file "cpfile", "sufile", or "dat", but
+nilfs_sysfs_create_device_group that creates those attributes is executed
+before the inodes for these metadata files are loaded, and
+nilfs_sysfs_delete_device_group which deletes these sysfs entries is
+called after releasing their metadata file inodes.
+
+Therefore, access to some of these sysfs attributes may occur outside of
+the lifetime of these metadata files, resulting in inode NULL pointer
+dereferences or use-after-free.
+
+In addition, the call to nilfs_sysfs_create_device_group() is made during
+the locking period of the semaphore "ns_sem" of nilfs object, so the
+shrinker call caused by the memory allocation for the sysfs entries, may
+derive lock dependencies "ns_sem" -> (shrinker) -> "locks acquired in
+nilfs_evict_inode()".
+
+Since nilfs2 may acquire "ns_sem" deep in the call stack holding other
+locks via its error handler __nilfs_error(), this causes lockdep to report
+circular locking. This is a false positive and no circular locking
+actually occurs as no inodes exist yet when
+nilfs_sysfs_create_device_group() is called. Fortunately, the lockdep
+warnings can be resolved by simply moving the call to
+nilfs_sysfs_create_device_group() out of "ns_sem".
+
+This fixes these sysfs issues by revising where the device's sysfs
+interface is created/deleted and keeping its lifetime within the lifetime
+of the metadata files above.
