The biggest fix is the restoration of mmap ioctl for gen12 integrated parts
which lack was breaking ADL-P with media stack.
Besides that a small selftest fix and a theoretical overflow on
i915->pipe_to_crtc_mapping.

Pull openat2 fixes from Christian Brauner:
- Remove the unused VALID_UPGRADE_FLAGS define we carried from an
extension to openat2() that we haven't merged. Aleksa might be
getting back to it at some point but just not right now.
- openat2() used to accidently ignore unknown flag values in the upper
32 bits.
The new openat2() syscall verifies that no unknown O-flag values are
set and returns an error to userspace if they are while the older
open syscalls like open() and openat() simply ignore unknown flag
values:
#define O_FLAG_CURRENTLY_INVALID (1 << 31)
struct open_how how = {
.flags = O_RDONLY | O_FLAG_CURRENTLY_INVALID,
.resolve = 0,
};
/* fails */
fd = openat2(-EBADF, "/dev/null", &how, sizeof(how));
/* succeeds */
fd = openat(-EBADF, "/dev/null", O_RDONLY | O_FLAG_CURRENTLY_INVALID);
However, openat2() silently truncates the upper 32 bits meaning:
#define O_FLAG_CURRENTLY_INVALID_LOWER32 (1 << 31)
#define O_FLAG_CURRENTLY_INVALID_UPPER32 (1 << 40)
struct open_how how_lowe32 = {
.flags = O_RDONLY | O_FLAG_CURRENTLY_INVALID_LOWER32,
};
struct open_how how_upper32 = {
.flags = O_RDONLY | O_FLAG_CURRENTLY_INVALID_UPPER32,
};
/* fails */
fd = openat2(-EBADF, "/dev/null", &how_lower32, sizeof(how_lower32));
/* succeeds */
fd = openat2(-EBADF, "/dev/null", &how_upper32, sizeof(how_upper32));
Fix this by preventing the immediate truncation in build_open_flags()
and add a compile-time check to catch when we add flags in the upper
32 bit range.
* tag 'fs.openat2.unknown_flags.v5.14' of git://git.kernel.org/pub/scm/linux/kernel/git/brauner/linux:

Pull mount_setattr updates from Christian Brauner:
"A few releases ago the old mount API gained support for a mount

support for it in the new mount api through the MOUNT_ATTR_NOSYMFOLLOW
flag via mount_setattr() and fsmount(). With mount_setattr() that flag
can even be applied recursively.

the nosymfollow patch. As I've already had the patches in my for-next

Header 'rt305x.h' is ralink architecture dependent file where
other general definitions which are in 'ralink_regs.h' are
being used. This 'rt305x.h' is only being included in two
different files: 'rt305x.c' and 'pinctrl-rt305x.c'. When
file 'pinctrl-rt305x.c' is being compiled definitions in
'ralink_regs.h' are need to build it properly. Hence, add
missing include 'ralink_regs.h' in 'pinctrl-rt305x.c'
source to avoid compilation problems.

The "dev->port[i].mp.mpi" is set to NULL during mlx5_ib_unbind_slave_port()
execution, however that field is needed to add device to unaffiliated list.
Such flow causes to the following kernel panic while unloading mlx5_ib
module in multi-port mode, hence the device should be added to the list
prior to unbind call.

Pull power management updates from Rafael Wysocki:
"These add hybrid processors support to the intel_pstate driver and
make it work with more processor models when HWP is disabled, make the
intel_idle driver use special C6 idle state paremeters when package
C-states are disabled, add cooling support to the tegra30 devfreq
driver, rework the TEO (timer events oriented) cpuidle governor,
extend the OPP (operating performance points) framework to use the
required-opps DT property in more cases, fix some issues and clean up
a number of assorted pieces of code.
Specifics:
- Make intel_pstate support hybrid processors using abstract
performance units in the HWP interface (Rafael Wysocki).
- Add Icelake servers and Cometlake support in no-HWP mode to
intel_pstate (Giovanni Gherdovich).
- Make cpufreq_online() error path be consistent with the CPU device
removal path in cpufreq (Rafael Wysocki).

fw_cfg_showrev() is called by an indirect call in kobj_attr_show(),
which violates clang's CFI checking because fw_cfg_showrev()'s second
parameter is 'struct attribute', whereas the ->show() member of 'struct
kobj_structure' expects the second parameter to be of type 'struct
kobj_attribute'.
$ cat /sys/firmware/qemu_fw_cfg/rev
3
$ dmesg | grep "CFI failure"
[ 26.016832] CFI failure (target: fw_cfg_showrev+0x0/0x8):
Fix this by converting fw_cfg_rev_attr to 'struct kobj_attribute' where
this would have been caught automatically by the incompatible pointer
types compiler warning. Update fw_cfg_showrev() accordingly.

Pull timer updates from Thomas Gleixner:
"Time and clocksource/clockevent related updates:
Core changes:
- Infrastructure to support per CPU "broadcast" devices for per CPU
clockevent devices which stop in deep idle states. This allows us
to utilize the more efficient architected timer on certain ARM SoCs
for normal operation instead of permanentely using the slow to
access SoC specific clockevent device.
- Print the name of the broadcast/wakeup device in /proc/timer_list
- Make the clocksource watchdog more robust against delays between
reading the current active clocksource and the watchdog
clocksource. Such delays can be caused by NMIs, SMIs and vCPU
preemption.
Handle this by reading the watchdog clocksource twice, i.e. before
and after reading the current active clocksource. In case that the
two watchdog reads shows an excessive time delta, the read sequence
is repeated up to 3 times.
- Improve the debug output and add a test module for the watchdog
mechanism.
- Reimplementation of the venerable time64_to_tm() function with a
faster and significantly smaller version. Straight from the source,
i.e. the author of the related research paper contributed this!
Driver changes:
- No new drivers, not even new device tree bindings!

resolution. Add the necessary core infrastructure.
- Provide a proper interface for modular PMU drivers to set the
interrupt affinity.
- Add a request flag which allows to exclude interrupts from spurious

always return IRQ_HANDLED which turns the spurious interrupt
detection into a pointless waste of CPU cycles.

tmmac: Add option to enable PHY WOL with PMT enabled
This patchset main objective is to provide an option to enable PHY WoL
even the PMT is enabled by default in the HW features.
The current stmmac driver WOL implementation will enable MAC WOL if
MAC HW PMT feature is on. Else, the driver will check for PHY WOL
support. Intel EHL mgbe are designed to wake up through PHY WOL
although the HW PMT is enabled.Hence, introduced use_phy_wol platform
data to provide this PHY WOL option. Set use_phy_wol will disable the
plat->pmt which currently used to determine the system to wake up by
MAC WOL or PHY WOL.
This WOL patchset includes of setting the device power state to D3hot.
This is because the EHL PSE will need to PSE mgbe to be in D3 state in
order for the PSE to goes into suspend mode.
Change Log:
V2: Drop Patch #3 net: stmmac: Reconfigure the PHY WOL settings in stmmac_resume().
====================
|
|
During suspend, set the Intel mgbe to D3hot state
to save power consumption.

The current stmmac driver WOL implementation will enable MAC WOL
if MAC HW PMT feature is on. Else, the driver will check for
PHY WOL support. There is another case where MAC HW PMT is
enabled but the platform still goes for the PHY WOL option.
E.g, Intel platform are designed for PHY WOL but not MAC WOL
although HW MAC PMT features are enabled.
Introduce use_phy_wol platform data to select PHY WOL
instead of depending on HW PMT features. Set use_phy_wol
will disable the plat->pmt which currently used to
determine the system to wake up by MAC WOL or PHY WOL.

"Static" is a loaded word, and probably not what the author meant when
the code was written.
In particular, this looks weird:
$ bridge fdb add dev swp0 00:01:02:03:04:05 local # totally fine, but
$ bridge fdb add dev swp0 00:01:02:03:04:05 static
[ 2020.708298] swp0: FDB only supports static addresses # hmm what?
By looking at the implementation which uses dev_uc_add/dev_uc_del it is
absolutely clear that only local addresses are supported, and the proper
Network Unreachability Detection state is being used for this purpose
(user space indeed sets NUD_PERMANENT when local addresses are meant).
So it is just the message that is wrong, fix it.

Use the more modern printk helper for network interfaces, which also
contains information about the associated struct device, and results in
overall shorter line lengths compared to printing an open-coded
dev->name.

When creating a PTP device, the configuration block allows
creation of an associated PPS device. However, there isn't
any way to associate the two devices after creation.
Set the PPS cookie, so pps_lookup_dev(ptp) performs correctly.

net: sock: add tracers for inet socket errors
this patch series introduce tracers for sk_error_report socket callback
calls. The use-case is that a user space application can monitor them
and making an own heuristic about bad peer connections even over a
socket lifetime. To make a specific example it could be use in the Linux
cluster world to fence a "bad" behaving node. For now it's okay to only
trace inet sockets. Other socket families can introduce their own tracers
easily.
Example output with trace-cmd:
<idle>-0 [003] 201.799437: inet_sk_error_report: family=AF_INET protocol=IPPROTO_TCP sport=21064 dport=38941 saddr=192.168.122.57 daddr=192.168.122.251 saddrv6=::ffff:192.168.122.57 daddrv6=::ffff:192.168.122.251 error=104

changes since v2:
- change "sk.sk_error_report(&ipc->sk);" to "sk_error_report(&ipc->sk);"

This patch will add tracers to trace inet socket errors only. A user
space monitor application can track connection errors indepedent from
socket lifetime and do additional handling. For example a cluster
manager can fence a node if errors occurs in a specific heuristic.
