+From 94aba76639cf4d5e30975d846bb0368db8202269 Mon Sep 17 00:00:00 2001
+From: Monis Khan <mkhan@redhat.com>
+Date: Wed, 12 Apr 2017 16:00:58 -0400
+Subject: [PATCH] encoding/asn1: support 31 bit identifiers with OID
+
+The current implementation uses a max of 28 bits when decoding an
+ObjectIdentifier. This change makes it so that an int64 is used to
+accumulate up to 35 bits. If the resulting data would not overflow
+an int32, it is used as an int. Thus up to 31 bits may be used to
+represent each subidentifier of an ObjectIdentifier.
+
+Fixes #19933
+
+Change-Id: I95d74b64b24cdb1339ff13421055bce61c80243c
