[ Upstream commit e8b374b649 ]
Module configuration may differ between its instances depending on
resources required and input and output audio format. Available
parameters to select from are stored in module resource and interface
(format) lists. These come from topology, together with description of
each of pipe's modules.
Ignoring index value provided by topology and relying always on 0th
entry leads to unexpected module behavior due to under/overbudged
resources assigned or impropper format selection. Fix by taking entry at
index specified by topology.

[ Upstream commit a28dc123fa ]
Patch 96b1454f2e ("gfs2: move freeze glock outside the make_fs_rw and _ro
functions") changed the gfs2 mount sequence so that it holds the freeze
lock before calling gfs2_make_fs_rw. Before this patch, gfs2_make_fs_rw
called init_threads to initialize the quotad and logd threads. That is a
problem if the system needs to withdraw due to IO errors early in the
mount sequence, for example, while initializing the system statfs inode:
1. An IO error causes the statfs glock to not sync properly after
recovery, and leaves items on the ail list.
2. The leftover items on the ail list causes its do_xmote call to fail,
which makes it want to withdraw. But since the glock code cannot
withdraw (because the withdraw sequence uses glocks) it relies upon
the logd daemon to initiate the withdraw.
3. The withdraw can never be performed by the logd daemon because all
this takes place before the logd daemon is started.
This patch moves function init_threads from super.c to ops_fstype.c
and it changes gfs2_fill_super to start its threads before holding the
freeze lock, and if there's an error, stop its threads after releasing
it. This allows the logd to run unblocked by the freeze lock. Thus,
the logd daemon can perform its withdraw sequence properly.

When adding the code to handle platform_get_irq*() errors in the commit
489447380a ("handle errors returned by platform_get_irq*()"), the
actual error code was enforced to be -ENXIO in the driver for some
strange reason. This didn't matter much until the deferred probing was
introduced -- which requires an actual error code to be propagated
upstream from the failure site.
While fixing this, also stop overriding the errors from request_irq() to
-EIO (done since the pre-git era).

Syzbot hit "task hung" bug in hci_req_sync(). The problem was in

Fix it by adding sanity check for timeout value to hci_inquiry().
Since hci_inquiry() is the only user of hci_req_sync() with user
controlled timeout value, it makes sense to check timeout value in
hci_inquiry() and don't touch hci_req_sync().

When scsi_dispatch_cmd was moved to scsi_lib.c and made static, some
compilers (i.e., at least gcc 8.4.0) decided to compile this
inline. This is a problem for lkdtm.ko, which inserted a kprobe
on this function for the SCSI_DISPATCH_CMD crashpoint.
Move this crashpoint one function up the call chain to
scsi_queue_rq. Though this is also a static function, it should never be
inlined because it is assigned as a structure entry. Therefore,
kprobe_register should always be able to find it.

[ Upstream commit 36ca7943ac ]
When the max pages (last_page in the swap header + 1) is smaller than
the total pages (inode size) of the swapfile, iomap_swapfile_activate
overwrites sis->max with total pages.
However, frontswap_map is a swap page state bitmap allocated using the
initial sis->max page count read from the swap header. If swapfile
activation increases sis->max, it's possible for the frontswap code to
walk off the end of the bitmap, thereby corrupting kernel memory.
[djwong: modify the description a bit; the original paragraph reads:
"However, frontswap_map is allocated using max pages. When test and clear
the sis offset, which is larger than max pages, of frontswap_map in
__frontswap_invalidate_page(), neighbors of frontswap_map may be
overwritten, i.e., slab is polluted."
Note also that this bug resulted in a behavioral change: activating a
swap file that was formatted and later extended results in all pages
being activated, not the number of pages recorded in the swap header.]
This fixes the issue by considering the limitation of max pages of swap
info in iomap_swapfile_add_extent().
To reproduce the case, compile kernel with slub RED ZONE, then run test:
$ sudo stress-ng -a 1 -x softlockup,resources -t 72h --metrics --times \
--verify -v -Y /root/tmpdir/stress-ng/stress-statistic-12.yaml \
--log-file /root/tmpdir/stress-ng/stress-logfile-12.txt \

[ 36.593956] Bluetooth: hci0: Firmware already downloaded
[ 46.814613] Bluetooth: hci0: Execution of wmt command timed out
[ 46.814619] Bluetooth: hci0: Failed to send wmt func ctrl (-110)
The shutdown callback depends on the result of hdev->rx_work, so we
should call it before flushing rx_work:
-> btmtksdio_shutdown()
-> mtk_hci_wmt_sync()
-> __hci_cmd_send()
-> wait for BTMTKSDIO_TX_WAIT_VND_EVT gets cleared
-> btmtksdio_recv_event()
-> hci_recv_frame()
-> queue_work(hdev->workqueue, &hdev->rx_work)
-> clears BTMTKSDIO_TX_WAIT_VND_EVT
So move the shutdown callback before flushing TX/RX queue to resolve the
issue.

The { 0 } doesn't clear all fields in the struct, but tells to the
compiler to set all fields to zero and doesn't touch any sub-fields
if they exists.
The {} is an empty initialiser that instructs to fully initialize whole

[ Upstream commit cea45a3bd2 ]
soc_device_match() is intended as a last resort, to handle e.g. quirks
that cannot be handled by matching based on a compatible value.
As the device nodes for the Renesas USB 3.0 Peripheral Controller on
R-Car E3 and RZ/G2E do have SoC-specific compatible values, the latter
can and should be used to match against these devices.
This also fixes support for the USB 3.0 Peripheral Controller on the
R-Car E3e (R8A779M6) SoC, which is a different grading of the R-Car E3
(R8A77990) SoC, using the same SoC-specific compatible value.

[ Upstream commit 6977cc89c8 ]
'of_find_device_by_node()' takes a reference that must be released when
not needed anymore.
This is expected to be done in 'dsi_destroy()'.
However, there are 2 issues in 'dsi_get_phy()'.
First, if 'of_find_device_by_node()' succeeds but 'platform_get_drvdata()'
returns NULL, 'msm_dsi->phy_dev' will still be NULL, and the reference
won't be released in 'dsi_destroy()'.
Secondly, as 'of_find_device_by_node()' already takes a reference, there is
no need for an additional 'get_device()'.
Move the assignment to 'msm_dsi->phy_dev' a few lines above and remove the
unneeded 'get_device()' to solve both issues.

[ Upstream commit e1dee2c1de ]
In commit 4e1a720d03 ("Bluetooth: avoid killing an already killed
socket"), a check was added to sco_sock_kill to skip killing a socket
if the SOCK_DEAD flag was set.
This was done after a trace for a use-after-free bug showed that the
same sock pointer was being killed twice.
Unfortunately, this check prevents sco_sock_kill from running on any
socket. sco_sock_kill kills a socket only if it's zapped and orphaned,
however sock_orphan announces that the socket is dead before detaching
it. i.e., orphaned sockets have the SOCK_DEAD flag set.
To fix this, we remove the check for SOCK_DEAD, and avoid repeated
calls to sco_sock_kill by removing incorrect calls in:
1. sco_sock_timeout. The socket should not be killed on timeout as
further processing is expected to be done. For example,
sco_sock_connect sets the timer then waits for the socket to be
connected or for an error to be returned.
2. sco_conn_del. This function should clean up resources for the
connection, but the socket itself should be cleaned up in
sco_sock_release.
3. sco_sock_close. Calls to sco_sock_close in sco_sock_cleanup_listen
and sco_sock_release are followed by sco_sock_kill. Hence the
duplicated call should be removed.
