+Subject: [PATCH] libmisc: fix default value in SHA_get_salt_rounds()
+
+If SHA_CRYPT_MIN_ROUNDS and SHA_CRYPT_MAX_ROUNDS are both unspecified,
+use SHA_ROUNDS_DEFAULT.
+
+Previously, the code fell through, calling shadow_random(-1, -1). This
+ultimately set rounds = (unsigned long) -1, which ends up being a very
+large number! This then got capped to SHA_ROUNDS_MAX later in the
+function.
+
+The new behavior matches BCRYPT_get_salt_rounds().
+
+Bug: https://bugs.gentoo.org/808195
+Fixes: https://github.com/shadow-maint/shadow/issues/393
+
+Upstream-Status: Backport [https://github.com/shadow-maint/shadow/commit/234e8fa7b134d1ebabfdad980a3ae5b63c046c62]
