Subject: [PATCH 02/10] Add support for disabling/enabling the use of DB for
verification
This lets a user disable the use of DB for verification purposes. The new
options "--ignore-db" and "--use-db" toggle the state of this. This sets
a UEFI variable called MokDB that makes MokManager prompt the user to approve
the setting after a reboot.
We refactor MokSBVar to MokToggleVar and set_validation to set_toggle, as
both MokDB and MokSB are really just toggle variables.

Coverity noticed that if read() returns error, we're doing string[-1].
We're also only reading some of the file in some cases. Replaced this
with a proper read loop.
Also we were overruning the string by one byte.

Subject: [PATCH 06/10] Use a read/realloc loop to avoid a race condition on
stat()
MIME-Version: 1.0

Coverity says:
4. shim-0.7/mokutil-0.2.0/src/mokutil.c:1228:toctou – Calling function
"open(char const *, int, ...)" that uses "key_file" after a check
function. This can cause a time-of-check, time-of-use race condition.
So with the new code we'll probably get garbage if somebody tries racing
that for some reason, but at least it'll be consistent garbage :)

Coverity says:
2. shim-0.7/mokutil-0.2.0/src/password-crypt.c:267:check_after_deref –
Null-checking "tmp" suggests that it may be null, but it has already
been dereferenced on all paths leading to the check.

Null-checking "tmp" suggests that it may be null, but it has already

But to me it looks like these were supposed to be checking for end-of-string
instead.

Subject: [PATCH 08/10] Make generate_pw_hash() somewhat cleaner.
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
Coverity needlessly complains:
2. shim-0.7/mokutil-0.2.0/src/mokutil.c:1322:check_after_deref –
Null-checking "password" suggests that it may be null, but it has
already been dereferenced on all paths leading to the check.
While this doesn't really make any difference, the whole ret and
error-path was overkill here, so I got rid of it.
