Hi!
Our coverity scan detected new CLANG warning after I have cherry-picked
commit 03345ecefeb0d82e3c3a4c28f27c3554f0611b39 [1] into our rhel8
release. It reported it for 2.79 version, but even the last commit in
master branch still has the same issue present. In attached patch I have
suggested fix.
I am not sure how to trigger this code from the client, so this is not
tested with real dhcp client. I track it under Fedora bug [2]. Coverity
reported it as:
1. Defect type: CLANG_WARNING
1. dnsmasq-2.79/src/rfc3315.c:344:7: warning[deadcode.DeadStores]: Value stored to 'outmsgtype' is never read
# 342|
# 343| {
# 344|-> outmsgtype = DHCP6REPLY;
# 345| o1 = new_opt6(OPTION6_STATUS_CODE);
# 346| put_opt6_short(DHCP6USEMULTI);
