There've been quite a few regression reports about the lowered volume
(reduced to ca 65% from the previous level) on Lenovo Thinkpad X1
after the commit d2cd795c4e ("ALSA: hda - fixup for the bass speaker
on Lenovo Carbon X1 7th gen"). Although the commit itself does the
right thing from HD-audio POV in order to have a volume control for
bass speakers, it seems that the machine has some secret recipe under
the hood.
Through experiments, Benjamin Poirier found out that the following
routing gives the best result:
* DAC1 (NID 0x02) -> Speaker pin (NID 0x14)
* DAC2 (NID 0x03) -> Shared by both Bass Speaker pin (NID 0x17) &
Headphone pin (0x21)
* DAC3 (NID 0x06) -> Unused
DAC1 seems to have some equalizer internally applied, and you'd get
again the output in a bad quality if you connect this to the
headphone pin. Hence the headphone is connected to DAC2, which is now
shared with the bass speaker pin. DAC3 has no volume amp, hence it's
not connected at all.
For achieving the routing above, this patch introduced a couple of
workarounds:
* The connection list of bass speaker pin (NID 0x17) is reduced not to
include DAC3 (NID 0x06)
* Pass preferred_pairs array to specify the fixed connection
Here, both workarounds are needed because the generic parser prefers
the individual DAC assignment over others.
When the routing above is applied, the generic parser creates the two
volume controls "Front" and "Bass Speaker". Since we have only two
DACs for three output pins, those are not fully controlling each
output individually, and it would confuse PulseAudio. For avoiding
the pitfall, in this patch, we rename those volume controls to some
unique ones ("DAC1" and "DAC2"). Then PulseAudio ignore them and
concentrate only on the still good-working "Master" volume control.
If a user still wants to control each DAC volume, they can still
change manually via "DAC1" and "DAC2" volume controls.

to determine whether the voltage should be read from PLANE2_VID

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.

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).

====================
RTL8366 stabilization
This stabilizes the RTL8366 driver by checking validity
of the passed VLANs and refactoring the member config
(MC) code so we do not require strict call order and
de-duplicate some code.
Changes from v1: incorporate review comments on patch
2.
Changes from v2: a oneline bug fix in patch 2.

The VLANs and PVIDs on the RTL8366 utilizes a "member
configuration" (MC) which is largely unexplained in the
code.
This set-up requires a special ordering: rtl8366_set_pvid()
must be called first, followed by rtl8366_set_vlan(),
else the MC will not be properly allocated. Relax this
by factoring out the code obtaining an MC and reuse
the helper in both rtl8366_set_pvid() and
rtl8366_set_vlan() so we remove this strict ordering
requirement.
In the process, add some better comments and debug prints
so people who read the code understand what is going on.

The rtl8366_set_vlan() and rtl8366_set_pvid() get invalid
VLANs tossed at it, especially VLAN0, something the hardware
and driver cannot handle. Check validity and bail out like
we do in the other callbacks.

__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);

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.

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.

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.
