Subject: BUG/MEDIUM: da: stop DeviceAtlas processing in the convertor if there is no input.
X-Git-Tag: v1.7-dev1~29
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=3b7113836db1f4f1bf35b475dceaa7366e90ad8e;p=thirdparty%2Fhaproxy.git

BUG/MEDIUM: da: stop DeviceAtlas processing in the convertor if there is no input.

In case a HTTP header modifier, like req*del, is used, the User-Agent would be removed
and cause a segfault, hence the work is stopped in due time.
