EDAC, pnd2: Build in a minimal sideband driver for Apollo Lake

I've been waing a long time for the generic sideband driver to
appear. Patience has run out, so include the minimum here to
just read registers.
Add a new action, SECCOMP_RET_LOG, that logs a syscall before allowing
the syscall. At the implementation level, this action is identical to
the existing SECCOMP_RET_ALLOW action. However, it can be very useful when
initially developing a seccomp filter for an application. The developer
can set the default action to be SECCOMP_RET_LOG, maybe mark any
obviously needed syscalls with SECCOMP_RET_ALLOW, and then put the
application through its paces. A list of syscalls that triggered the
default action (SECCOMP_RET_LOG) can be easily gleaned from the logs and
that list can be used to build the syscall whitelist. Finally, the
developer can change the default action to the desired value.
This provides a more friendly experience than seeing the application get
killed, then updating the filter and rebuilding the app, seeing the
application get killed due to a different syscall, then updating the
filter and rebuilding the app, etc.
The functionality is similar to what's supported by the various LSMs.
SELinux has permissive mode, AppArmor has complain mode, SMACK has
bring-up mode, etc.
SECCOMP_RET_LOG is given a lower value than SECCOMP_RET_ALLOW as allow
while logging is slightly more restrictive than quietly allowing.
Unfortunately, the tests added for SECCOMP_RET_LOG are not capable of
inspecting the audit log to verify that the syscall was logged.
With this patch, the logic for deciding if an action will be logged is:
if action == RET_ALLOW:
do not log
else if action == RET_KILL && RET_KILL in actions_logged:
log
else if action == RET_LOG && RET_LOG in actions_logged:

seccomp: Filter flag to log all actions except SECCOMP_RET_ALLOW
Add a new filter flag, SECCOMP_FILTER_FLAG_LOG, that enables logging for
all actions except for SECCOMP_RET_ALLOW for the given filter.
SECCOMP_RET_KILL actions are always logged, when "kill" is in the
actions_logged sysctl, and SECCOMP_RET_ALLOW actions are never logged,
regardless of this flag.
This flag can be used to create noisy filters that result in all
non-allowed actions to be logged. A process may have one noisy filter,
which is loaded with this flag, as well as a quiet filter that's not
loaded with this flag. This allows for the actions in a set of filters
to be selectively conveyed to the admin.
Since a system could have a large number of allocated seccomp_filter
structs, struct packing was taken in consideration. On 64 bit x86, the
new log member takes up one byte of an existing four byte hole in the
struct. On 32 bit x86, the new log member creates a new four byte hole
(unavoidable) and consumes one of those bytes.
Unfortunately, the tests added for SECCOMP_FILTER_FLAG_LOG are not
capable of inspecting the audit log to verify that the actions taken in
the filter were logged.

seccomp: Selftest for detection of filter flag support
Userspace needs to be able to reliably detect the support of a filter
flag. A good way of doing that is by attempting to enter filter mode,
with the flag bit(s) in question set, and a NULL pointer for the args
parameter of seccomp(2). EFAULT indicates that the flag is valid and
EINVAL indicates that the flag is invalid.
This patch adds a selftest that can be used to test this method of

seccomp: Sysctl to configure actions that are allowed to be logged
Adminstrators can write to this sysctl to set the seccomp actions that
are allowed to be logged. Any actions not found in this sysctl will not
be logged.
For example, all SECCOMP_RET_KILL, SECCOMP_RET_TRAP, and
SECCOMP_RET_ERRNO actions would be loggable if "kill trap errno" were
written to the sysctl. SECCOMP_RET_TRACE actions would not be logged
since its string representation ("trace") wasn't present in the sysctl
value.
The path to the sysctl is:
/proc/sys/kernel/seccomp/actions_logged
The actions_avail sysctl can be read to discover the valid action names
that can be written to the actions_logged sysctl with the exception of
"allow". SECCOMP_RET_ALLOW actions cannot be configured for logging.
The default setting for the sysctl is to allow all actions to be logged
except SECCOMP_RET_ALLOW. While only SECCOMP_RET_KILL actions are
currently logged, an upcoming patch will allow applications to request
additional actions to be logged.
There's one important exception to this sysctl. If a task is
specifically being audited, meaning that an audit context has been
allocated for the task, seccomp will log all actions other than
SECCOMP_RET_ALLOW despite the value of actions_logged. This exception
preserves the existing auditing behavior of tasks with an allocated
audit context.
With this patch, the logic for deciding if an action will be logged is:
if action == RET_ALLOW:
do not log
else if action == RET_KILL && RET_KILL in actions_logged:

Userspace code that needs to check if the kernel supports a given action
may not be able to use the /proc/sys/kernel/seccomp/actions_avail
sysctl. The process may be running in a sandbox and, therefore,
sufficient filesystem access may not be available. This patch adds an
operation to the seccomp(2) syscall that allows userspace code to ask
the kernel if a given action is available.
If the action is supported by the kernel, 0 is returned. If the action
is not supported by the kernel, -1 is returned with errno set to
-EOPNOTSUPP. If this check is attempted on a kernel that doesn't support
this new operation, -1 is returned with errno set to -EINVAL meaning
that userspace code will have the ability to differentiate between the
two error cases.

seccomp: Sysctl to display available actions
This patch creates a read-only sysctl containing an ordered list of
seccomp actions that the kernel supports. The ordering, from left to
right, is the lowest action value (kill) to the highest action value
(allow). Currently, a read of the sysctl file would return "kill trap
errno trace allow". The contents of this sysctl file can be useful for
userspace code as well as the system administrator.
The path to the sysctl is:
/proc/sys/kernel/seccomp/actions_avail
libseccomp and other userspace code can easily determine which actions
the current kernel supports. The set of actions supported by the current
kernel may be different than the set of action macros found in kernel
headers that were installed where the userspace code was built.
In addition, this sysctl will allow system administrators to know which
actions are supported by the kernel and make it easier to configure
exactly what seccomp logs through the audit subsystem. Support for this
level of logging configuration will come in a future patch.

Config options which are '-' for a given flavor may have values
specified in common configuration files. Thus the initial config
file created by concatinating the fragments will have values for
these options which Kconfig will later delete.
However, when 'fdr editconfig' is run and the prompt to edit a
given configuration is declined, Kconfig does not modify the
config and these values remain. If any of these values is
enforced config-check will produce an error. We need to run
'make slientoldconfig' in this case so that the config files
will be accurate.

UBUNTU: SAUCE: (efi-lockdown) efi: Don't print secure boot state from the efi stub
During boot the efi stub prints what amounts to debugging
messages about the secure boot state to the efi console. which
appear on the screen during boot. The same information is printed
in dmesg while the kernel is booting, so they serve no purpose
aside from debugging issues in the efi stub. Remove them.
