+Subject: [PATCH] lsmmc: replace strncpy with memmove on overlapping memory
+ copy
+
+here source and destination addresses are overlapping so using memmove is
+going to be more efficient.
+
+Additionally, the bounded size for copy is overflowing for first copy
+
+In function 'strncpy',
+    inlined from 'read_file' at lsmmc.c:356:3:
+/mnt/a/oe/build/tmp/work/cortexa7t2hf-neon-vfpv4-bec-linux-gnueabi/mmc-utils/0.1-r0/recipe-sysroot/usr/include/bits/string_fortified.h:106:10: error: '__builtin_strncpy' accessing 4096 bytes at offsets 0 and 1 overlaps 4095 bytes at offset 1 [-Werror=restrict]
+   return __builtin___strncpy_chk (__dest, __src, __len, __bos (__dest));
+          ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
