net: dsa: Setup dsa_netdev_ops
This patch series addresses the overloading of a DSA CPU/management
interface's netdev_ops for the purpose of providing useful information
from the switch side.
Up until now we had duplicated the existing netdev_ops structure and
added specific function pointers to return information of interest. Here
we have a more controlled way of doing this by involving the specific
netdev_ops function pointers that we want to be patched, which is easier
for auditing code in the future. As a byproduct we can now maintain
netdev_ops pointer comparisons which would be failing before (no known
in tree problems because of that though).
Let me know if this approach looks reasonable to you and we might do the
same with our ethtool_ops overloading as well.
Changes in v2:
- use static inline int vs. static int inline (Kbuild robot)
- fixed typos in patch 4 (Andrew)
- avoid using macros (Andrew)

The IMA_APPRAISE_BOOTPARAM config allows enabling different "ima_appraise="
modes - log, fix, enforce - at run time, but not when IMA architecture
specific policies are enabled. This prevents properly labeling the
filesystem on systems where secure boot is supported, but not enabled on the
platform. Only when secure boot is actually enabled should these IMA
appraise modes be disabled.
This patch removes the compile time dependency and makes it a runtime
decision, based on the secure boot state of that platform.
Test results as follows:
-> x86-64 with secure boot enabled
[ 0.015637] Kernel command line: <...> ima_policy=appraise_tcb ima_appraise=fix
[ 0.015668] ima: Secure boot enabled: ignoring ima_appraise=fix boot parameter option
-> powerpc with secure boot disabled
[ 0.000000] Kernel command line: <...> ima_policy=appraise_tcb ima_appraise=fix
[ 0.000000] Secure boot mode disabled
-> Running the system without secure boot and with both options set:
CONFIG_IMA_APPRAISE_BOOTPARAM=y
CONFIG_IMA_ARCH_POLICY=y

From "ima: Fix rule parsing bugs and extend KEXEC_CMDLINE rule support"
coverletter.
This series ultimately extends the supported IMA rule conditionals for
the KEXEC_CMDLINE hook function. As of today, there's an imbalance in
IMA language conditional support for KEXEC_CMDLINE rules in comparison
to KEXEC_KERNEL_CHECK and KEXEC_INITRAMFS_CHECK rules. The KEXEC_CMDLINE
rules do not support *any* conditionals so you cannot have a sequence of
rules like this:
dont_measure func=KEXEC_KERNEL_CHECK obj_type=foo_t
dont_measure func=KEXEC_INITRAMFS_CHECK obj_type=foo_t
dont_measure func=KEXEC_CMDLINE obj_type=foo_t
measure func=KEXEC_KERNEL_CHECK
measure func=KEXEC_INITRAMFS_CHECK
measure func=KEXEC_CMDLINE
Instead, KEXEC_CMDLINE rules can only be measured or not measured and
there's no additional flexibility in today's implementation of the
KEXEC_CMDLINE hook function.
With this series, the above sequence of rules becomes valid and any
calls to kexec_file_load() with a kernel and initramfs inode type of
foo_t will not be measured (that includes the kernel cmdline buffer)
while all other objects given to a kexec_file_load() syscall will be
measured. There's obviously not an inode directly associated with the
kernel cmdline buffer but this patch series ties the inode based
decision making for KEXEC_CMDLINE to the kernel's inode. I think this
will be intuitive to policy authors.
While reading IMA code and preparing to make this change, I realized
that the buffer based hook functions (KEXEC_CMDLINE and KEY_CHECK) are
quite special in comparison to longer standing hook functions. These
buffer based hook functions can only support measure actions and there
are some restrictions on the conditionals that they support. However,
the rule parser isn't enforcing any of those restrictions and IMA policy
authors wouldn't have any immediate way of knowing that the policy that
they wrote is invalid. For example, the sequence of rules above parses
successfully in today's kernel but the
"dont_measure func=KEXEC_CMDLINE ..." rule is incorrectly handled in
ima_match_rules(). The dont_measure rule is *always* considered to be a
match so, surprisingly, no KEXEC_CMDLINE measurements are made.
While making the rule parser more strict, I realized that the parser
does not correctly free all of the allocated memory associated with an
ima_rule_entry when going down some error paths. Invalid policy loaded
by the policy administrator could result in small memory leaks.

Take the properties of the kexec kernel's inode and the current task
ownership into consideration when matching a KEXEC_CMDLINE operation to
the rules in the IMA policy. This allows for some uniformity when
writing IMA policy rules for KEXEC_KERNEL_CHECK, KEXEC_INITRAMFS_CHECK,
and KEXEC_CMDLINE operations.
Prior to this patch, it was not possible to write a set of rules like
this:
dont_measure func=KEXEC_KERNEL_CHECK obj_type=foo_t
dont_measure func=KEXEC_INITRAMFS_CHECK obj_type=foo_t
dont_measure func=KEXEC_CMDLINE obj_type=foo_t
measure func=KEXEC_KERNEL_CHECK
measure func=KEXEC_INITRAMFS_CHECK
measure func=KEXEC_CMDLINE
The inode information associated with the kernel being loaded by a
kexec_kernel_load(2) syscall can now be included in the decision to
measure or not
Additonally, the uid, euid, and subj_* conditionals can also now be
used in KEXEC_CMDLINE rules. There was no technical reason as to why
those conditionals weren't being considered previously other than
ima_match_rules() didn't have a valid inode to use so it immediately
bailed out for KEXEC_CMDLINE operations rather than going through the
full list of conditional comparisons.

Use ima_validate_rule(), at the end of the token parsing stage, to
verify combinations of actions, hooks, and flags. This is useful to
increase readability by consolidating such checks into a single function
and also because rule conditionals can be specified in arbitrary order
making it difficult to do comprehensive rule validation until the entire
rule has been parsed.
This allows for the check that ties together the "keyrings" conditional
with the KEY_CHECK function hook to be moved into the final rule
validation.
The modsig check no longer needs to compiled conditionally because the
token parser will ensure that modsig support is enabled before accepting
"imasig|modsig" appraise type values. The final rule validation will
ensure that appraise_type and appraise_flag options are only present in
appraise rules.
Finally, this allows for the check that ties together the "pcr"
conditional with the measure action to be moved into the final rule
validation.
