Subject: [PATCH] DnsResolver: Support wildcards in cached hosts file
|
|
|
|
If an exact name is not found in the hosts file and the host name
|
|
contains at least one dot, search for entries of the form "*.domain",
|
|
where domain is the portion of the host name after the first dot. If
|
|
that is not found, repeat using the domain.
|
|
|
|
Example: a.b.c.example.com would search for the following in turn:
|
|
a.b.c.example.com
|
|
*.b.c.example.com
|
|
*.c.example.com
|
|
*.example.com
|
|
*.com
|
|
|
|
Note: this change is the analogue of the bionic change of the same name.
|
|
Both should be kept in sync.
