Subject: Fix: jhash.h: remove out-of-bound reads
X-Git-Url: http://drtracing.org/?a=commitdiff_plain;h=ec9e040d128545d43b7d29106b70581bca42b1c3;hp=ec9e040d128545d43b7d29106b70581bca42b1c3;p=lttng-ust.git

Fix: jhash.h: remove out-of-bound reads

jhash.h implements "special" code for valgrind because it reads memory
out-of-bound (and then applies a mask) when reading strings.

Considering that lttng-ust does not use jhash.h in a fast-path, remove
this "optimization" and use the verifiable VALGRIND code instead. This
fixes an ASan splat.

Fixes: #1238
