UBUNTU: SAUCE: apparmor: open userns related sysctl so lxc can check if restriction are in place

BugLink: http://bugs.launchpad.net/bugs/2040194
https://github.com/canonical/lxd/issues/11920#issuecomment-1756110109

lxc and lxd currently need to determine if the apparmor restriction
on unprivileged user namespaces are being enforced, so that apparmor
restrictions won't break lxc/d, and they won't clutter the logs
by doing something like

  unshare true

to test if the restrictions are being enforced.

Ideally access to this information would be restricted so that any
unknown access would be logged, but lxc/d currently aren't ready for
this so in order to _not_ force lxc/d to probe whether enforcement is
enabled, open up read access to the sysctls for unprivileged user
namespace mediation.

UBUNTU: SAUCE: apparmor: fix request field from a prompt reply that denies all access

BugLink: http://bugs.launchpad.net/bugs/2040192

A reply to a prompt request that denies all permissions requested will
throw the following warning, because the auditing code does not expect
the request field to be empty when generating the audit message.

Note: this does not change the mediation, it just ensures the assert in
the audit path does not trigger, polluting dmesg and the kernel audit log.

UBUNTU: SAUCE: apparmor: fix notification header size

BugLink: https://bugs.launchpad.net/bugs/2040250

When strings are appended to the notification the header size should
be updated to reflect the correct size. While the size is also
directly returned as part of delivering the notification, the header
should also be update to conform to specification and allow for
verification.

If verification is enabled and the notification contains appended
strings then notifications fail verification and won't be delivered.

Since there's no guarantee that all the callbacks can work in atomic
context, switch to use blocking_notifier_call_chain to relax the
constraint.

io_uring: add a sysctl to disable io_uring system-wide

BugLink: https://bugs.launchpad.net/bugs/2035116

Introduce a new sysctl (io_uring_disabled) which can be either 0, 1, or
2. When 0 (the default), all processes are allowed to create io_uring
instances, which is the current behavior. When 1, io_uring creation is
disabled (io_uring_setup() will fail with -EPERM) for unprivileged
processes not in the kernel.io_uring_group group. When 2, calls to
io_uring_setup() fail with -EPERM regardless of privilege.

ALSA: hda/realtek - ALC287 I2S speaker platform support

BugLink: https://bugs.launchpad.net/bugs/2037077

0x17 was only speaker pin, DAC assigned will be 0x03. Headphone
assigned to 0x02.
Playback via headphone will get EQ filter processing. So,it needs to
swap DAC.
