When we now use the new kernel_read_file_from_path() we
are reporting a failure when we iterate over all the paths
possible for firmware. Before using kernel_read_file_from_path()
we only reported a failure once we confirmed a file existed
with filp_open() but failed with fw_read_file_contents().
With kernel_read_file_from_path() both are done for us and
we obviously are now reporting too much information given that
some optional paths will always fail and clutter the logs.
fw_get_filesystem_firmware() already has a check for failure
and uses an internal flag, FW_OPT_NO_WARN, but this does not
let us capture other unxpected errors. This enables that

We currently cannot do appraisal or signature vetting of IMA policies
since we currently can only load IMA policies by writing the contents
of the policy directly in, as follows:
cat policy-file > <securityfs>/ima/policy
If we provide the kernel the path to the IMA policy so it can load
the policy itself it'd be able to later appraise or vet the file
signature if it has one. This patch adds support to load the IMA
policy with a given path as follows:
echo /etc/ima/ima_policy > /sys/kernel/security/ima/policy
Changelog v4+:
- moved kernel_read_file_from_path() error messages to callers
v3:
- moved kernel_read_file_from_path() to a separate patch
v2:
- after re-ordering the patches, replace calling integrity_kernel_read()
to read the file with kernel_read_file_from_path() (Mimi)

Add IMA policy support for measuring/appraising the kexec image and
initramfs. Two new IMA policy identifiers KEXEC_KERNEL_CHECK and
KEXEC_INITRAMFS_CHECK are defined.
Example policy rules:
measure func=KEXEC_KERNEL_CHECK
appraise func=KEXEC_KERNEL_CHECK appraise_type=imasig
measure func=KEXEC_INITRAMFS_CHECK
appraise func=KEXEC_INITRAMFS_CHECK appraise_type=imasig
Moving the enumeration to the vfs layer simplified the patches, allowing
the IMA changes, for the most part, to be separated from the other
changes. Unfortunately, passing either a kernel_read_file_id or a
ima_hooks enumeration within IMA is messy.
Option 1: duplicate kernel_read_file enumeration in ima_hooks
enum kernel_read_file_id {
...
READING_KEXEC_IMAGE,
READING_KEXEC_INITRAMFS,
READING_MAX_ID
enum ima_hooks {
...
KEXEC_KERNEL_CHECK
KEXEC_INITRAMFS_CHECK
Option 2: define ima_hooks as extension of kernel_read_file
eg: enum ima_hooks {
FILE_CHECK = READING_MAX_ID,
MMAP_CHECK,
In order to pass both kernel_read_file_id and ima_hooks values, we
would need to specify a struct containing a union.
struct caller_id {
union {
enum ima_hooks func_id;
enum kernel_read_file_id read_id;
};
};
Option 3: incorportate the ima_hooks enumeration into kernel_read_file_id,
perhaps changing the enumeration name.
For now, duplicate the new READING_KEXEC_IMAGE/INITRAMFS in the ima_hooks.
Changelog v4:
- replaced switch statement with a kernel_read_file_id to an ima_hooks
id mapping array - Dmitry
- renamed ima_hook tokens KEXEC_CHECK and INITRAMFS_CHECK to
KEXEC_KERNEL_CHECK and KEXEC_INITRAMFS_CHECK respectively - Dave Young

Each time a file is read by the kernel, the file should be re-measured and
the file signature re-appraised, based on policy. As there is no need to
preserve the status information, this patch replaces the firmware and
module specific cache status with a generic one named read_file.
This change simplifies adding support for other files read by the kernel.

Replace copy_module_from_fd() with kernel_read_file_from_fd().
Although none of the upstreamed LSMs define a kernel_module_from_file
hook, IMA is called, based on policy, to prevent unsigned kernel modules
from being loaded by the original kernel module syscall and to
measure/appraise signed kernel modules.
The security function security_kernel_module_from_file() was called prior
to reading a kernel module. Preventing unsigned kernel modules from being
loaded by the original kernel module syscall remains on the pre-read
kernel_read_file() security hook. Instead of reading the kernel module
twice, once for measuring/appraising and again for loading the kernel
module, the signature validation is moved to the kernel_post_read_file()
security hook.
This patch removes the security_kernel_module_from_file() hook and security
call.

Replace the fw_read_file_contents with kernel_file_read_from_path().
Although none of the upstreamed LSMs define a kernel_fw_from_file hook,
IMA is called by the security function to prevent unsigned firmware from
being loaded and to measure/appraise signed firmware, based on policy.
Instead of reading the firmware twice, once for measuring/appraising the
firmware and again for reading the firmware contents into memory, the
kernel_post_read_file() security hook calculates the file hash based on
the in memory file buffer. The firmware is read once.

These days there exists a few mechanisms in the kernel that do just
this though to load a file into a local buffer. There are minor but

Simplify a few of the *generic* shared dev_warn() and dev_dbg()
print messages for three reasons:
0) Historically firmware_class code was added to help
get device driver firmware binaries but these days
request_firmware*() helpers are being repurposed for
general *system data* needed by the kernel.
1) This will also help generalize shared code as much as possible
later in the future in consideration for a new extensible firmware
API which will enable to separate usermode helper code out as much
as possible.
2) Kees Cook pointed out the the prints already have the device
associated as dev_*() helpers are used, that should help identify
the user and case in which the helpers are used. That should provide
enough context and simplifies the messages further.
v4: generalize debug/warn messages even further as suggested by
Kees Cook.

The TPM core has long assumed that every device has a driver attached,
however the force path was attaching the TPM core outside of a driver
context. This isn't generally reliable as the user could detatch the
driver using sysfs or something, but commit b8b2c7d845d5 ("base/platform:
assert that dev_pm_domain callbacks are called unconditionally")
forced the issue by leaving the driver pointer NULL if there is
no probe.
Rework the TPM setup to create a platform device with resources and
then allow the driver core to naturally bind and probe it through the
normal mechanisms. All this structure is needed anyhow to enable TPM
for OF environments.
Finally, since the entire flow is changing convert the init/exit to use
the modern ifdef-less coding style when possible

This does a request_resource under the covers which means tis holds a
lock on the memory range it is using so other drivers cannot grab it.
When doing probing it is important to ensure that other drivers are
not using the same range before tis starts touching it.
To do this flow the actual struct resource from the device right

few more than usual.
Most of these are fixes and tweaks to board support (DT bugfixes,
etc). I've also picked up a couple of small cleanups that seemed
innocent enough that there was little reason to wait (const/
__initconst and Kconfig deps).
Quite a bit of the changes on OMAP were due to fixes to no longer
write to rodata from assembly when ARM_KERNMEM_PERMS was enabled, but
there were also other fixes.
Kirkwood had a bunch of gpio fixes for some boards. OMAP had RTC
fixes on OMAP5, and Nomadik had changes to MMC parameters in DT.
All in all, mostly the usual mix of various fixes"
