Justin Viiret	c8e01a3d62	util-hash-lookup3: Add hashlittle_safe() variant By default, hashlittle() will read off the end of the key, up to the next four-byte boundary, although the data beyond the end of the key doesn't affect the hash. This read causes uninitialized read warnings from Valgrind and Address Sanitizer. Here we add hashlittle_safe(), which avoids reading off the end of the buffer (using the code inside the VALGRIND-guarded block in the original hashlittle() implementation).	10 years ago

util-hash-lookup3: Add hashlittle_safe() variant

By default, hashlittle() will read off the end of the key, up to the
next four-byte boundary, although the data beyond the end of the key
doesn't affect the hash. This read causes uninitialized read warnings
from Valgrind and Address Sanitizer.

Here we add hashlittle_safe(), which avoids reading off the end of the
buffer (using the code inside the VALGRIND-guarded block in the original
hashlittle() implementation).
