+Subject: [PATCH] libopeniscsiusr: Compare with max int instead of max long
+
+This compares value member of int_list_tbl struct which is of unsigned
+int type.
+
+struct int_list_tbl {
+const char *name;
+unsigned int value;
+};
+
+Clang compiler reports this comparison when
+-Wtautological-constant-out-of-range-compare is enabled
+
+| idbm.c:1042:2: error: result of comparison of constant 18446744073709551615 with expression of type 'unsigned int' is always true [-Werror,-Wtautological-constant-out-of-range-compare]
+|         _rec_int_list(SESSION_CHAP_ALGS, recs, node, session.auth.chap_algs,
+|         ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+| idbm.c:263:23: note: expanded from macro '_rec_int_list'
+|                 if (_org->_name[_i] != ~0UL) { \
+|                     ~~~~~~~~~~~~~~~ ^  ~~~~
+
+Since max value for int can be less than unsinged long e.g. on LP64 its
+better to use UINT_MAX here
