+Subject: ALSA: hda/cirrus - support for iMac 12,1 model
+
+From: Allen Ballway <ballway@chromium.org>
+
+commit 74bba640d69914cf832b87f6bbb700e5ba430672 upstream.
+
+The 12,1 model requires the same configuration as the 12,2 model
+to enable headphones but has a different codec SSID. Adds
+12,1 SSID for matching quirk.

+Subject: fs: Add missing umask strip in vfs_tmpfile
+
+From: Yang Xu <xuyang2018.jy@fujitsu.com>
+
+commit ac6800e279a22b28f4fc21439843025a0d5bf03e upstream.
+
+All creation paths except for O_TMPFILE handle umask in the vfs directly
+if the filesystem doesn't support or enable POSIX ACLs. If the filesystem
+does then umask handling is deferred until posix_acl_create().
+Because, O_TMPFILE misses umask handling in the vfs it will not honor
+umask settings. Fix this by adding the missing umask handling.

+Subject: usbnet: Fix linkwatch use-after-free on disconnect
+
+From: Lukas Wunner <lukas@wunner.de>
+
+commit a69e617e533edddf3fa3123149900f36e0a6dc74 upstream.
+
+usbnet uses the work usbnet_deferred_kevent() to perform tasks which may
+sleep. On disconnect, completion of the work was originally awaited in
+->ndo_stop(). But in 2003, that was moved to ->disconnect() by historic
+commit "[PATCH] USB: usbnet, prevent exotic rtnl deadlock":
+
+ https://git.kernel.org/tglx/history/c/0f138bbfd83c
+
+The change was made because back then, the kernel's workqueue
+implementation did not allow waiting for a single work. One had to wait
+for completion of *all* work by calling flush_scheduled_work(), and that
+could deadlock when waiting for usbnet_deferred_kevent() with rtnl_mutex
+held in ->ndo_stop().
+
+The commit solved one problem but created another: It causes a
+use-after-free in USB Ethernet drivers aqc111.c, asix_devices.c,
+ax88179_178a.c, ch9200.c and smsc75xx.c:
+
+* If the drivers receive a link change interrupt immediately before
+ disconnect, they raise EVENT_LINK_RESET in their (non-sleepable)
+ ->status() callback and schedule usbnet_deferred_kevent().
+* usbnet_deferred_kevent() invokes the driver's ->link_reset() callback,
+ which calls netif_carrier_{on,off}().
+* That in turn schedules the work linkwatch_event().
+
+Because usbnet_deferred_kevent() is awaited after unregister_netdev(),
+netif_carrier_{on,off}() may operate on an unregistered netdev and
+linkwatch_event() may run after free_netdev(), causing a use-after-free.
+
+In 2010, usbnet was changed to only wait for a single instance of
+usbnet_deferred_kevent() instead of *all* work by commit 23f333a2bfaf
+("drivers/net: don't use flush_scheduled_work()").
+
+Unfortunately the commit neglected to move the wait back to
+->ndo_stop(). Rectify that omission at long last.

+Subject: vfs: Check the truncate maximum size in inode_newsize_ok()
+
+From: David Howells <dhowells@redhat.com>
+
+commit e2ebff9c57fe4eb104ce4768f6ebcccf76bef849 upstream.
+
+If something manages to set the maximum file size to MAX_OFFSET+1, this
+can cause the xfs and ext4 filesystems at least to become corrupt.
+
+Ordinarily, the kernel protects against userspace trying this by
+checking the value early in the truncate() and ftruncate() system calls
+calls - but there are at least two places that this check is bypassed:
+
+ (1) Cachefiles will round up the EOF of the backing file to DIO block
+ size so as to allow DIO on the final block - but this might push
+ the offset negative. It then calls notify_change(), but this
+ inadvertently bypasses the checking. This can be triggered if
+ someone puts an 8EiB-1 file on a server for someone else to try and
+ access by, say, nfs.
+
+ (2) ksmbd doesn't check the value it is given in set_end_of_file_info()
+ and then calls vfs_truncate() directly - which also bypasses the
+ check.
+
+In both cases, it is potentially possible for a network filesystem to
+cause a disk filesystem to be corrupted: cachefiles in the client's
+cache filesystem; ksmbd in the server's filesystem.
+
+nfsd is okay as it checks the value, but we can then remove this check
+too.
+
+Fix this by adding a check to inode_newsize_ok(), as called from
+setattr_prepare(), thereby catching the issue as filesystems set up to
+perform the truncate with minimal opportunity for bypassing the new
+check.
+
+Fixes: 1f08c925e7a3 ("cachefiles: Implement backing file wrangling")
+Fixes: f44158485826 ("cifsd: add file operations")
