Subject: [PATCH] cms: store digest as pointer instead of index
Storage as an index is problematic because the sentinel value -1 was
used, but accesses were unchecked, leading to crashes like that in
3b1031a6b779cb80c11b34eec84c5a0cc215efed ("pesigcheck: Fix crash on
digest match"). By storing a pointer, we get an explicit NULL
dereference: still a crash, but preferred since it's clearer.
Since the index was previously also used for retrieving digest
parameters, include a pointer to the relevant struct digest_param in the
struct digest.

Subject: [PATCH] Work around GCC being obnoxiously incompatible with GCC
GCC added and then later removed the diagnostic flag
"-Wanalyzer-use-of-uninitialized-value", and so this doesn't work with
newer versions of GCC.
This patch removes the previous workaround for when it didn't work well.
I really wish any of our compilers had any sense of rigor with this
stuff at all.

Subject: [PATCH] get_password_passthrough(): handle the callback context right
Right now, we have a few callback functions for PK11_Authenticate(), and
they take different arguments. This is incorrect; none of the callers
ever pass anything through except our CMS context.
This fixes get_password_passthrough() to correctly accept the CMS
context and get the passthrough data from cms->pwdata instead of trying
to treat the CMS context as the pwdata.

Right now, when we read the password/PIN from a file, we're pruning the
end of the string from the file we read indiscriminately. If you don't
have a newline, that means we're cutting off the final digits of the
text.
This changes it to prune only common special characters from the
pinfile, but also to prune /all/ of them.

From 0000000000000000000000000000000000000000 Mon Sep 17 00:00:00 2001

Subject: [PATCH] Revert "cms: store digest as pointer instead of index"
In 926782c216532a83f9ff864dee39d2349d61fd23, we switched
cms->selected_digest to be a pointer to the member of the digests array
rather than an index. Unfortunately this is just as bad, because the
bugs that come up wind up setting pointers to NULL+(selected*offset),
i.e. 0x10, and that doesn't get us any closer to actually finding any
problem.
For now, the new approach is going to be to make it an index again, but
to default it to 0 (sha256) rather than -1, so if it isn't set at the
correct part of the lifecycle it'll just default to the (nearly always)
correct choice.
This reverts commit 926782c216532a83f9ff864dee39d2349d61fd23.

Subject: [PATCH] CMS: add some minor cleanups
We reverted 926782c216532a83f9ff864dee39d2349d61fd23 so that a future
patch can try a different approach, but that commit also had a few
cleanups that are worthwhile on their own.
This patch re-introduces the cleanup to move "struct digest_param" to a
more reasonable place and the cleanup to check_hash(), and takes it just
a bit farther.

Subject: [PATCH] CMS: make cms->selected_digest an index (again)
In 926782c216532a83f9ff864dee39d2349d61fd23, we switched
cms->selected_digest to be a pointer to the entry in cms->digests.
Because cms->digests is lazily allocated, setting the selected_digest
pointer has to be done at the right part of the CMS context life cycle,
and in some cases it clearly is not:

There is also a similar issue in the daemon code, and how to fix it
there is not immediately clear to me.
Currently, we realistically only support using sha256 digests, so for
now I've chosen to paper over the issue by switching back to
cms->selected_digest be an index into both ctx->digests and
digest_params, but switching the default value from -1 to 0, aka
DIGEST_PARAM_SHA256. We can revisit this issue later whenever we add
sha384 support (or whichever other digest).
