@ -316,18 +315,47 @@ Most distributors ship glib-networking built with GnuTLS, and
most apps use glib-networking, so this isn't a net-new library
in most cases.
mcatanzaro note: I've updated Colin's original patch to implement
g_hmac_copy() using gnutls_hmac_copy(), which didn't exist when Colin
developed this patch.
=======================================================================
mcatanzaro note:
I've updated Colin's original patch with several enhancements:
Implement g_hmac_copy() using gnutls_hmac_copy(), which didn't exist
when Colin developed this patch.
Removed use of GSlice
Better error checking in g_hmac_new(). It is possible for
gnutls_hmac_init() to fail if running in FIPS mode and an MD5 digest is
requested. In this case, we should return NULL rather than returning a
broken GHmac with a NULL gnutls_hmac_hd_t. This was leading to a later
null pointer dereference inside gnutls_hmac_update(). Applications are
responsible for checking to ensure the return value of g_hmac_new() is
not NULL since it is annotated as nullable. Added documentation to
indicate this possibility.
Properly handle length -1 in g_hmac_update(). This means we've been
given a NUL-terminated string and should use strlen(). GnuTLS doesn't
accept -1, so let's call strlen() ourselves.
Crash the application with g_error() if gnutls_hmac() fails for any
reason. This is necessary because g_hmac_update() is not fallible, so we
have no way to indicate error. Crashing seems better than returning the
wrong result later when g_hmac_get_string() or g_hmac_get_digest() is
later called. (Those functions are also not fallible.) Fortunately, I
don't think this error should actually be hit in practice.

Subject: [PATCH 3/4] dlopen GnuTLS instead of linking directly
I'd like to enable our GnuTLS GHmac patchset in Fedora in order to
ensure it is receiving sufficient real-world testing, since we've
discovered several bugs thus far. Problem is Fedora has one requirement
that RHEL does not: it needs to build glib as a static lib. This is
needed by QEMU in Fedora for complicated technical reasons that I don't
understand. However, nothing in RHEL needs it. This means we failed to
notice that glib2-static is broken in RHEL, because there is no
gnutls-static! We could fix this by adding a gnutls-static package, but
that seems like overkill, and adding more static libraries where they're
not truly necessary is not the direction we want to move in anyway. So
instead, let's just dlopen GnuTLS to sidestep this problem entirely.
This would not be a good solution for upstream, but upstream has made
clear that this patchset is already non-upstreamable, so it will be fine
for our purposes.

Subject: [PATCH 4/4] Add test for GHmac in FIPS mode
This will test a few problems that we hit recently:
g_hmac_copy() is broken, https://bugzilla.redhat.com/show_bug.cgi?id=1786538
Crash in g_hmac_update() in FIPS mode, https://bugzilla.redhat.com/show_bug.cgi?id=1971533
Crash when passing -1 length to g_hmac_update() (discovered in #1971533)
We'll also test to ensure MD5 fails, and stop compiling the other MD5
tests.
