+
+The dropbearkey utility built in x32 abi format, when generating ssh
+keys, was getting lost in the infinite loop.
+
+This patch fixes the issue by fixing types of variables and
+parameters of functions used in the code, which were getting
+undesired size, when compiled with the x32 abi toolchain.

+Typdef mp_digit to unsigned long long for MP_64BIT
+
+When GCC is used with MP_64BIT, we should typedef mp_digit to unsigned
+long long instead of unsigned long since for x32, unsigned long is
+32-bit and unsigned long long is 64-bit and it is safe to use unsigned
+long long for 64-bit integer with GCC.

+Subject: [PATCH] fix libtomcrypt/libtommath ordering
+
+To prevent build failures when using system libtom libraries and
+linking with --as-needed, LIBTOM_LIBS should be in the order
+-ltomcrypt -ltommath, not the other way around, ie libs should be
+prepended to LIBTOM_LIBS as they are found, not appended.
+
+Note that LIBTOM_LIBS is not used when linking with the bundled
+libtom libs.
+
+Upstream-Status: Backport [ https://github.com/mkj/dropbear/commit/f9e6bc2aecab0f4b5b529e07a92cc63c8a66cd4b ]
