+Subject: ALSA: jack: Fix mutex call in snd_jack_report()
+MIME-Version: 1.0

+
+From: Takashi Iwai <tiwai@suse.de>
+
+commit 89dbb335cb6a627a4067bc42caa09c8bc3326d40 upstream.
+
+snd_jack_report() is supposed to be callable from an IRQ context, too,
+and it's indeed used in that way from virtsnd driver. The fix for
+input_dev race in commit 1b6a6fc5280e ("ALSA: jack: Access input_dev
+under mutex"), however, introduced a mutex lock in snd_jack_report(),
+and this resulted in a potential sleep-in-atomic.
+
+For addressing that problem, this patch changes the relevant code to
+use the object get/put and removes the mutex usage. That is,
+snd_jack_report(), it takes input_get_device() and leaves with
+input_put_device() for assuring the input_dev being assigned.
+
+Although the whole mutex could be reduced, we keep it because it can
+be still a protection for potential races between creation and
+deletion.

+Subject: ALSA: pcm: Fix potential data race at PCM memory allocation helpers
+
+From: Takashi Iwai <tiwai@suse.de>
+
+commit bd55842ed998a622ba6611fe59b3358c9f76773d upstream.
+
+The PCM memory allocation helpers have a sanity check against too many
+buffer allocations. However, the check is performed without a proper
+lock and the allocation isn't serialized; this allows user to allocate
+more memories than predefined max size.
+
+Practically seen, this isn't really a big problem, as it's more or
+less some "soft limit" as a sanity check, and it's not possible to
+allocate unlimitedly. But it's still better to address this for more
+consistent behavior.
+
+The patch covers the size check in do_alloc_pages() with the
+card->memory_mutex, and increases the allocated size there for
+preventing the further overflow. When the actual allocation fails,
+the size is decreased accordingly.

+Subject: block: add overflow checks for Amiga partition support
+
+From: Michael Schmitz <schmitzmic@gmail.com>
+
+commit b6f3f28f604ba3de4724ad82bea6adb1300c0b5f upstream.
+
+The Amiga partition parser module uses signed int for partition sector
+address and count, which will overflow for disks larger than 1 TB.
+
+Use u64 as type for sector address and size to allow using disks up to
+2 TB without LBD support, and disks larger than 2 TB with LBD. The RBD
+format allows to specify disk sizes up to 2^128 bytes (though native
+OS limitations reduce this somewhat, to max 2^68 bytes), so check for
+u64 overflow carefully to protect against overflowing sector_t.
+
+Bail out if sector addresses overflow 32 bits on kernels without LBD
+support.
+
+This bug was reported originally in 2012, and the fix was created by
+the RDB author, Joanne Dow <jdow@earthlink.net>. A patch had been
+discussed and reviewed on linux-m68k at that time but never officially
+submitted (now resubmitted as patch 1 in this series).
+This patch adds additional error checking and warning messages.

+Subject: block: change all __u32 annotations to __be32 in affs_hardblocks.h
+
+From: Michael Schmitz <schmitzmic@gmail.com>
+
+commit 95a55437dc49fb3342c82e61f5472a71c63d9ed0 upstream.
+
+The Amiga partition parser module uses signed int for partition sector
+address and count, which will overflow for disks larger than 1 TB.
+
+Use u64 as type for sector address and size to allow using disks up to
+2 TB without LBD support, and disks larger than 2 TB with LBD. The RBD
+format allows to specify disk sizes up to 2^128 bytes (though native
+OS limitations reduce this somewhat, to max 2^68 bytes), so check for
+u64 overflow carefully to protect against overflowing sector_t.
+
+This bug was reported originally in 2012, and the fix was created by
+the RDB author, Joanne Dow <jdow@earthlink.net>. A patch had been
+discussed and reviewed on linux-m68k at that time but never officially
+submitted (now resubmitted as patch 1 of this series).
+
+Patch 3 (this series) adds additional error checking and warning
+messages. One of the error checks now makes use of the previously
+unused rdb_CylBlocks field, which causes a 'sparse' warning
+(cast to restricted __be32).
+
+Annotate all 32 bit fields in affs_hardblocks.h as __be32, as the
+on-disk format of RDB and partition blocks is always big endian.

+(see patch 3 of this series for that).

+Subject: block: increment diskseq on all media change events
+
+From: Demi Marie Obenour <demi@invisiblethingslab.com>
+
+commit b90ecc0379eb7bbe79337b0c7289390a98752646 upstream.
+
+Currently, associating a loop device with a different file descriptor
+does not increment its diskseq. This allows the following race
+condition:
+
+1. Program X opens a loop device
+2. Program X gets the diskseq of the loop device.
+3. Program X associates a file with the loop device.
+4. Program X passes the loop device major, minor, and diskseq to
+ something.
+5. Program X exits.
+6. Program Y detaches the file from the loop device.
+7. Program Y attaches a different file to the loop device.
+8. The opener finally gets around to opening the loop device and checks
+ that the diskseq is what it expects it to be. Even though the
+ diskseq is the expected value, the result is that the opener is
+ accessing the wrong file.
+
+From discussions with Christoph Hellwig, it appears that
+disk_force_media_change() was supposed to call inc_diskseq(), but in
+fact it does not. Adding a Fixes: tag to indicate this. Christoph's
+Reported-by is because he stated that disk_force_media_change()
+calls inc_diskseq(), which is what led me to discover that it should but
+does not.

+Subject: btrfs: fix race when deleting free space root from the dirty cow roots list
+
+From: Filipe Manana <fdmanana@suse.com>
+
+commit babebf023e661b90b1c78b2baa384fb03a226879 upstream.
+
+When deleting the free space tree we are deleting the free space root
+from the list fs_info->dirty_cowonly_roots without taking the lock that
+protects it, which is struct btrfs_fs_info::trans_lock.
+This unsynchronized list manipulation may cause chaos if there's another
+concurrent manipulation of this list, such as when adding a root to it
+with ctree.c:add_root_to_dirty_list().
+
+This can result in all sorts of weird failures caused by a race, such as
+the following crash:
