+Subject: [PATCH] iproute2: fix hidden uint to uin64_t promottion in json_print
+
+print_int used 'int' type internally, whereas print_uint used 'uint64_t'
+
+These helper functions eventually call vfprintf(fp, fmt, args) which is
+a variable argument list function and is dependent upon 'fmt' containing
+correct information about the length of the passed arguments.
+
+Unfortunately print_int v print_uint offered no clue to the programmer
+that internally passed ints to print_uint were being promoted to 64bits,
+thus the format passed in 'fmt' string vs the actual passed integer
+could be different lengths. This is even more interesting on big endian
+architectures where 'vfprintf' would be looking in the middle of an
+int64 type. Symptoms of this included tc qdisc showing bizzarre values
+for a variety of fields across a variety of qdiscs (e.g. refcnt, flows,
+quantum)
+
+print_u/int now stick with native int size.
+
+A similar patch has been sent upstream.
+
+Fixes FS#1425
