46815bf4d5 dmaengine: ti: k3-udma: Update rchan_oes_offset for am654 SYSFW ABI 3.0
SYSFW ABI 3.0 has changed the rchan_oes_offset value for am654 to support
SR2.

Since the kernel now needs SYSFW API 3.0 to work because the merged irqchip
update, we need to also update the am654 rchan_oes_offset.

a255e9c869 drm/nouveau/kms/gv100-: Include correct push header in crcc37d.c
Looks like when we converted everything over to Nvidia's class headers,
we mistakenly included the nvif/push507b.h instead of nvif/pushc37b.h,
which resulted in breaking CRC reporting for volta+:

nouveau 0000:1f:00.0: disp: chid 0 stat 10003361 reason 3
[RESERVED_METHOD] mthd 0d84 data 00000000 code 00000000

fc8c70526b drm/radeon: Prefer lower feedback dividers
Commit 2e26ccb119 ("drm/radeon: prefer lower reference dividers")
fixed screen flicker for HP Compaq nx9420 but breaks other laptops like
Asus X50SL.

Turns out we also need to favor lower feedback dividers.

Users confirmed this change fixes the regression and doesn't regress the
original fix.

d98299885c drm/amdgpu: Fix bug in reporting voltage for CIK
On my R9 390, the voltage was reported as a constant 1000 mV.
This was due to a bug in smu7_hwmgr.c, in the smu7_read_sensor()
function, where some magic constants were used in a condition,
to determine whether the voltage should be read from PLANE2_VID
or PLANE1_VID. The VDDC mask was incorrectly used, instead of
the VDDGFX mask.

This patch changes the code to use the correct defined constants
(and apply the correct bitshift), thus resulting in correct voltage reporting.

f7b2e34b4a drm/amdgpu: Specify get_argument function for ci_smu_funcs
Starting in Linux 5.8, the graphics and memory clock frequency were not being
reported for CIK cards. This is a regression, since they were reported correctly
in Linux 5.7.

After investigation, I discovered that the smum_send_msg_to_smc() function,
attempts to call the corresponding get_argument() function of ci_smu_funcs.
However, the get_argument() function is not defined in ci_smu_funcs.

This patch fixes the bug by specifying the correct get_argument() function.

2a63866c8b tipc: fix shutdown() of connectionless socket
syzbot is reporting hung task at nbd_ioctl() [1], for there are two
problems regarding TIPC's connectionless socket's shutdown() operation.

----------
#include <fcntl.h>
#include <sys/socket.h>
#include <sys/ioctl.h>
#include <linux/nbd.h>
#include <unistd.h>

int main(int argc, char *argv[])
{
        const int fd = open("/dev/nbd0", 3);
        alarm(5);
        ioctl(fd, NBD_SET_SOCK, socket(PF_TIPC, SOCK_DGRAM, 0));
        ioctl(fd, NBD_DO_IT, 0); /* To be interrupted by SIGALRM. */
        return 0;
}
----------

One problem is that wait_for_completion() from flush_workqueue() from
nbd_start_device_ioctl() from nbd_ioctl() cannot be completed when
nbd_start_device_ioctl() received a signal at wait_event_interruptible(),
for tipc_shutdown() from kernel_sock_shutdown(SHUT_RDWR) from
nbd_mark_nsock_dead() from sock_shutdown() from nbd_start_device_ioctl()
is failing to wake up a WQ thread sleeping at wait_woken() from
tipc_wait_for_rcvmsg() from sock_recvmsg() from sock_xmit() from
nbd_read_stat() from recv_work() scheduled by nbd_start_device() from
nbd_start_device_ioctl(). Fix this problem by always invoking
sk->sk_state_change() (like inet_shutdown() does) when tipc_shutdown() is
called.

The other problem is that tipc_wait_for_rcvmsg() cannot return when
tipc_shutdown() is called, for tipc_shutdown() sets sk->sk_shutdown to
SEND_SHUTDOWN (despite "how" is SHUT_RDWR) while tipc_wait_for_rcvmsg()
needs sk->sk_shutdown set to RCV_SHUTDOWN or SHUTDOWN_MASK. Fix this
problem by setting sk->sk_shutdown to SHUTDOWN_MASK (like inet_shutdown()
does) when the socket is connectionless.

05d4487197 ipv6: Fix sysctl max for fib_multipath_hash_policy
Cited commit added the possible value of '2', but it cannot be set. Fix
it by adjusting the maximum value to '2'. This is consistent with the
corresponding IPv4 sysctl.

Before:

# sysctl -w net.ipv6.fib_multipath_hash_policy=2
sysctl: setting key "net.ipv6.fib_multipath_hash_policy": Invalid argument
net.ipv6.fib_multipath_hash_policy = 2
# sysctl net.ipv6.fib_multipath_hash_policy
net.ipv6.fib_multipath_hash_policy = 0

After:

# sysctl -w net.ipv6.fib_multipath_hash_policy=2
net.ipv6.fib_multipath_hash_policy = 2
# sysctl net.ipv6.fib_multipath_hash_policy
net.ipv6.fib_multipath_hash_policy = 2

2b7bcd967a drivers/net/wan/hdlc: Change the default of hard_header_len to 0
Change the default value of hard_header_len in hdlc.c from 16 to 0.

Currently there are 6 HDLC protocol drivers, among them:

hdlc_raw_eth, hdlc_cisco, hdlc_ppp, hdlc_x25 set hard_header_len when
attaching the protocol, overriding the default. So this patch does not
affect them.

hdlc_raw and hdlc_fr don't set hard_header_len when attaching the
protocol. So this patch will change the hard_header_len of the HDLC
device for them from 16 to 0.

This is the correct change because both hdlc_raw and hdlc_fr don't have
header_ops, and the code in net/packet/af_packet.c expects the value of
hard_header_len to be consistent with header_ops.

In net/packet/af_packet.c, in the packet_snd function,
for AF_PACKET/DGRAM sockets it would reserve a headroom of
hard_header_len and call dev_hard_header to fill in that headroom,
and for AF_PACKET/RAW sockets, it does not reserve the headroom and
does not call dev_hard_header, but checks if the user has provided a
header of length hard_header_len (in function dev_validate_header).

We recently added some calls to clk_disable_unprepare() but we missed
the last error path if register_netdev() fails.

I made a couple cleanups so we avoid mistakes like this in the future.
First I reversed the "if (!ret)" condition and pulled the code in one
indent level.  Also, the "port->netdev = NULL;" is not required because
"port" isn't used again outside this function so I deleted that line.

3a653b205f dm thin metadata: Fix use-after-free in dm_bm_set_read_only
The following error ocurred when testing disk online/offline:

[  301.798344] device-mapper: thin: 253:5: aborting current metadata transaction
[  301.848441] device-mapper: thin: 253:5: failed to abort metadata transaction
[  301.849206] Aborting journal on device dm-26-8.
[  301.850489] EXT4-fs error (device dm-26) in __ext4_new_inode:943: Journal has aborted
[  301.851095] EXT4-fs (dm-26): Delayed block allocation failed for inode 398742 at logical offset 181 with max blocks 19 with error 30
[  301.854476] BUG: KASAN: use-after-free in dm_bm_set_read_only+0x3a/0x40 [dm_persistent_data]

Reason is:

 metadata_operation_failed
    abort_transaction
        dm_pool_abort_metadata
	    __create_persistent_data_objects
	        r = __open_or_format_metadata
	        if (r) --> If failed will free pmd->bm but pmd->bm not set NULL
		    dm_block_manager_destroy(pmd->bm);
    set_pool_mode
	dm_pool_metadata_read_only(pool->pmd);
	dm_bm_set_read_only(pmd->bm);  --> use-after-free

Add checks to see if pmd->bm is NULL in dm_bm_set_read_only and
dm_bm_set_read_write functions.  If bm is NULL it means creating the
bm failed and so dm_bm_is_read_only must return true.

3b5455636f libata: implement ATA_HORKAGE_MAX_TRIM_128M and apply to Sandisks
All three generations of Sandisk SSDs lock up hard intermittently.
Experiments showed that disabling NCQ lowered the failure rate significantly
and the kernel has been disabling NCQ for some models of SD7's and 8's,
which is obviously undesirable.

Karthik worked with Sandisk to root cause the hard lockups to trim commands
larger than 128M. This patch implements ATA_HORKAGE_MAX_TRIM_128M which
limits max trim size to 128M and applies it to all three generations of
Sandisk SSDs.

ae03594716 ALSA: hda: add dev_dbg log when driver is not selected
On SKL+ Intel platforms, the driver selection is handled by the
snd_intel_dspcfg, and when the HDaudio legacy driver is not selected,
be it with the auto-selection or user preferences with a kernel
parameter, the probe aborts with no logs, only a -ENODEV return value.

Having no dmesg trace, even with dynamic debug enabled, makes support
more complicated than it needs to be, and even experienced users can
be fooled. A simple dev_dbg() trace solves this problem.

13774d81f3 ALSA: hda: fix a runtime pm issue in SOF when integrated GPU is disabled
In snd_hdac_device_init pm_runtime_set_active is called to
increase child_count in parent device. But when it is failed
to build connection with GPU for one case that integrated
graphic gpu is disabled, snd_hdac_ext_bus_device_exit will be
invoked to clean up a HD-audio extended codec base device. At
this time the child_count of parent is not decreased, which
makes parent device can't get suspended.

This patch calls pm_runtime_set_suspended to decrease child_count
in parent device in snd_hdac_device_exit to match with
snd_hdac_device_init. pm_runtime_set_suspended can make sure that
it will not decrease child_count if the device is already suspended.

355afaeb57 io_uring: no read/write-retry on -EAGAIN error and O_NONBLOCK marked file
Actually two things that need fixing up here:

- The io_rw_reissue() -EAGAIN retry is explicit to block devices and
  regular files, so don't ever attempt to do that on other types of
  files.

- If we hit -EAGAIN on a nonblock marked file, don't arm poll handler for
  it. It should just complete with -EAGAIN.
