Use router_get_my_routerinfo() rather than desc_routerinfo
The following functions use desc_routerinfo where they could use router_get_my_routerinfo():
This could cause issues if desc_routerinfo needs to be rebuilt, because some of these functions don't call router_get_my_routerinfo() first.
Others have comments about desc_routerinfo that might need to be updated:
- Also change "IPv6 and IPv6 entries" to "IPv4 and IPv6 entries"
