802.11ay specification defines Enhanced Directional Multi-Gigabit
(EDMG) STA and AP which allow channel bonding of 2 channels and more.
Introduce new NL attributes that are needed for enabling and
configuring EDMG support.
Two new attributes are used by kernel to publish driver's EDMG
capabilities to the userspace:
NL80211_BAND_ATTR_EDMG_CHANNELS - bitmap field that indicates the 2.16
GHz channel(s) that are supported by the driver.
When this attribute is not set it means driver does not support EDMG.
NL80211_BAND_ATTR_EDMG_BW_CONFIG - represent the channel bandwidth
configurations supported by the driver.
Additional two new attributes are used by the userspace for connect
command and for AP configuration:
NL80211_ATTR_WIPHY_EDMG_CHANNELS
NL80211_ATTR_WIPHY_EDMG_BW_CONFIG
New rate info flag - RATE_INFO_FLAGS_EDMG, can be reported from driver
and used for bitrate calculation that will take into account EDMG
according to the 802.11ay specification.

Bug: 150628559
Signed-off-by: Connor O'Brien <connoro@google.com>
When searching for the best lowest_mask with a fitness_fn passed, make
sure we record the lowest_level that returns a valid lowest_mask so that
we can use that as a fallback in case we fail to find a fitting CPU at
all levels.
The intention in the original patch was not to allow a down migration to
unfitting CPU. But this missed the case where we are already running on
unfitting one.
With this change now RT tasks can still move between unfitting CPUs when
they're already running on such CPU.
And as Steve suggested; to adhere to the strict priority rules of RT, if
a task is already running on a fitting CPU but due to priority it can't
run on it, allow it to downmigrate to unfitting CPU so it can run.

commit ae62cf5eb2 upstream.
Newer GCC warns about possible truncations of two generated path names as
we're concatenating the configurable sysfs and debugfs path prefixes
with a filename and placing the results in buffers of the same size as
the maximum length of the prefixes.
snprintf(d->name, MAX_STR_LEN, "gb_loopback%u", dev_id);
snprintf(d->sysfs_entry, MAX_SYSFS_PATH, "%s%s/",
t->sysfs_prefix, d->name);
snprintf(d->debugfs_entry, MAX_SYSFS_PATH, "%sraw_latency_%s",
t->debugfs_prefix, d->name);
Fix this by separating the maximum path length from the maximum prefix
length and reducing the latter enough to fit the generated strings.
Note that we also need to reduce the device-name buffer size as GCC
isn't smart enough to figure out that we ever only used MAX_STR_LEN
bytes of it.

commit f160238348 upstream.
Newer GCC warns about a possible truncation of a generated sysfs path
name as we're concatenating a directory path with a file name and
placing the result in a buffer that is half the size of the maximum
length of the directory path (which is user controlled).
loopback_test.c: In function 'open_poll_files':
loopback_test.c:651:31: warning: '%s' directive output may be truncated writing up to 511 bytes into a region of size 255 [-Wformat-truncation=]
651 | snprintf(buf, sizeof(buf), "%s%s", dev->sysfs_entry, "iteration_count");
| ^~
loopback_test.c:651:3: note: 'snprintf' output between 16 and 527 bytes into a destination of size 255
651 | snprintf(buf, sizeof(buf), "%s%s", dev->sysfs_entry, "iteration_count");
| ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Fix this by making sure the buffer is large enough the concatenated
strings.

commit f50b7daccc upstream.
On a system configured to trigger a crash_kexec() reboot, when only one CPU
is online and another CPU panics while starting-up, crash_smp_send_stop()
will fail to send any STOP message to the other already online core,
resulting in fail to freeze and registers not properly saved.
Moreover even if the proper messages are sent (case CPUs > 2)
it will similarly fail to account for the booting CPU when executing
the final stop wait-loop, so potentially resulting in some CPU not
been waited for shutdown before rebooting.
A tangible effect of this behaviour can be observed when, after a panic
with kexec enabled and loaded, on the following reboot triggered by kexec,
the cpu that could not be successfully stopped fails to come back online:

Make crash_smp_send_stop() account also for the online status of the
calling CPU while evaluating how many CPUs are effectively online: this way
the right number of STOPs is sent and all other stopped-cores's registers
are properly saved.
