+Subject: [PATCH] netd: Sort and cache hosts file data for fast lookup
+
+The hosts file is normally searched linearly.  This is very slow when
+the file is large.  To mitigate this, read the hosts file and sort the
+entries in an in-memory cache.  When an address is requested via
+gethostbyname or getaddrinfo, binary search the cache.
+
+In case where the cache is not available, return a suitable error code
+and fall back to the existing lookup code.
+
+This has been written to behave as much like the existing lookup code as
+possible.  But note bionic and glibc differ in behavior for some corner
+cases.  Choose the most standard compliant behavior for these where
+possible.  Otherwise choose the behavior that seems most reasonable.
+
+Note: this change is the analogue of the bionic change of the same name.
+Both should be kept in sync.
+

+Subject: [PATCH] netd: 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.
