Log statements from ima_mok.c, ima_asymmetric_keys.c, and
ima_queue_keys.c are prefixed with the respective file names
and not with the string "ima".
This change fixes the log statement prefix to be consistent with the rest
of the IMA files.

Before listing the specific filenames, the patch description should
provide a generic explanation of the problem. For example, the kernel
Makefile "obj-$CONFIG_XXXX" specifies object files which may be built
as loadable kernel modules[1].

process_buffer_measurement() does not have log messages for failure
conditions.
This change adds a log statement in the above function.

Hi Tushar,
Please remove the period at the end of the Subject line.

I agree some form of notification needs to be added. The question is
whether the failure should be audited or a kernel message emitted.
IMA emits audit messages (integrity_audit_msg) for a number of
reasons - on failure to calculate a file hash, invalid policy rules,
failure to communicate with the TPM, signature verification errors,
etc.

With 3/3 "IMA: Add module name and base name prefix to log", the
resulting message will be "KBUILD_MODNAME: KBUILD_BASENAME: func:".
Isn't that a bit much?

I believe both IMA audit messages and kernel message should be emitted -
for better discoverability and diagnosability.

For this specific message, it will look like below.
"ima: ima_main: process_buffer_measurement: failed, result: %d"
In general, adding KBUILD_BASENAME seems helpful to pinpoint the
location of the issue.

Like file measurement failures, failure to measure a key or the boot
command line should be audited as well. For debugging purposes, you
could make this message pr_devel.

The #define for formatting log messages, pr_fmt, is duplicated in the
files under security/integrity.
This change moves the definition to security/integrity/integrity.h and
removes the duplicate definitions in the other files under
security/integrity. Also, it adds KBUILD_MODNAME and KBUILD_BASENAME prefix
to the log messages.

Joe, Shuah, including the pr_fmt() in integrity/integrity.h not only
affects the integrity directory but everything below it. Adding
KBUILD_BASENAME to pr_fmt() modifies all of the existing IMA and EVM
kernel messages. Is that ok or should there be a separate pr_fmt()
for the subdirectories?
thanks,
Mimi

Log messages are often consumed by log monitors, which mostly use
pattern matching to find messages they're interested in, so you have to
take some care when changing the messages the kernel spits out and you
have to make sure any change gets well notified so the distributions
can warn about it.
For this one, can we see a "before" and "after" message so we know
what's happening?

Mimi and James,
My suggestion was based on thinking that simplifying this by removing
duplicate defines. Some messages are missing modules names, adding
module name to them does change the messages.
If using one pr_fmt for all modules changes the world and makes it
difficult for log monitors, I would say it isn't a good change.
I will leave this totally up to Mimi to decide. Feel free to throw
out my suggestion if it leads more trouble than help. :)
thanks,

Thanks, Shuah. Tushar, I don't see any need for changing the existing
IMA/EVM messages. Either remove the KBUILD_BASENAME from the format
or limit the new format to the integrity directory.

Ok. I will remove the KBUILD_BASENAME from the format.
And I will keep the definition in security/integrity/integrity.h, and
will keep the duplicates removed - as originally proposed in this patch
v3 3/3.
