net: force LookupAddr results to be rooted DNS paths when using cgo Go 1.4 and before have always returned DNS names with a trailing dot for reverse lookups, as they do for basically all other routines returning DNS names. Go 1.4 and before always implemented LookupAddr using pure Go (not C library calls). Go 1.5 added the ability to make a C library call to implement LookupAddr. Unfortunately the C library call returns a DNS name without a trailing dot (an unrooted name), meaning that if turn off cgo during make.bash then you still get the rooted name but with cgo on you get an unrooted name. The unrooted name is inconsistent with the pure Go implementation and with all previous Go releases, so change it to a rooted name. Fixes #12189.

Unless otherwise noted, the Go source files are distributed under the BSD-style license found in the LICENSE file.
If you have just untarred a binary Go distribution, you need to set the environment variable $GOROOT to the full path of the go directory (the one containing this file). You can omit the variable if you unpack it into /usr/local/go, or if you rebuild from sources by running all.bash (see doc/install-source.html). You should also add the Go binary directory $GOROOT/bin to your shell's path.
For example, if you extracted the tar file into $HOME/go, you might put the following in your .profile:
export GOROOT=$HOME/go export PATH=$PATH:$GOROOT/bin
