>Description:
relayd gives a nonsense error if a relay has two protocols but the
first is invalid.
>How-To-Repeat:
```
# relayd.conf
table <web> { "127.0.0.1" }
table <app> { "127.0.0.1" }
http protocol web {
return error
# syntax error: missing quotes:
tls ca file /etc/ssl/cert.pem
}
http protocol web_app {
return error
match request path "/app/*" forward to <app>
}
relay https_proxy {
listen on 0.0.0.0 port 80
protocol web
forward to <web> port 8080
protocol web_app
forward to <app> port 8082
}
```
```
$ doas relayd -d -v -f relayd.conf
startup
relayd.conf:8: syntax error
relayd.conf:20: no such protocol: web
relayd.conf:23: protocol web_app defined twice
no actions, nothing to do
unused protocol: web_app
ca exiting, pid 3075
relay exiting, pid 71928
pfe exiting, pid 81431
hce exiting, pid 95455
ca exiting, pid 62478
relay exiting, pid 9500
relay exiting, pid 64011
ca exiting, pid 18935
```
Or,
```
# relayd.conf
table <web> { "127.0.0.1" }
table <app> { "127.0.0.1" }
http protocol web {
return error
tls ca file "/etc/ssl/cert.pem"
}
http protocol blah {
return error
match request path "/app/*" forward to <app>
}
relay https_proxy {
listen on 0.0.0.0 port 80
# error: undefined protocol
protocol web2
forward to <app> port 8082
protocol web
forward to <web> port 8080
}
```
```
$ doas relayd -d -v -f relayd.conf
startup
relayd.conf:20: no such protocol: web2
relayd.conf:23: protocol web defined twice
no actions, nothing to do
unused protocol: web
unused protocol: blah
hce exiting, pid 49635
pfe exiting, pid 65232
ca exiting, pid 43948
ca exiting, pid 20719
ca exiting, pid 85785
relay exiting, pid 21295
relay exiting, pid 13943
relay exiting, pid 46257
```
Those protocols were never defined twice, of course.
