Subject: Fix bug in fuzzstub.
X-Git-Tag: 5.0.2~186^2~105
X-Git-Url: https://gerrit.automotivelinux.org/gerrit/gitweb?a=commitdiff_plain;h=be9c9bb55cea9ddac4c47041a5875f824629d03e;p=apps%2Fagl-service-can-low-level.git

Fix bug in fuzzstub.

The fread call always returned a message length of 1 byte,
making the fuzz stub used for external fuzzers useless. The
normal fuzztest.c was unaffected.

Bug found using afl-fuzz.
