The Linaro git appear to be getting some very suspicious traffic on our
git protocol port. Its causing our servers to fail and effectively DOS
us. We are currently trying to block offending IPs. However, the number
of malicious IPs is growing and we may have to shut off the git protocol
daemon on our servers while we find a way to prevent this.

If you are using the "smart" protocol, https://git.linaro.org/.... you
will not be affected. If you aren't using the smart protocol, it might
be a good time to consider updating your .git/config files.
