Re: [undertow-dev] how to disable io exception logging

hello undertow developers! we are trying to disable logging of io exceptions like the comment in UndertowLogger.java suggests: /** * Logger used for IO exceptions. Generally these should be suppressed, because they are of little interest, and it is easy for an * attacker to fill up the logs by intentionally causing IO exceptions. */ UndertowLogger REQUEST_IO_LOGGER = Logger.getMessageLogger(UndertowLogger.class, UndertowLogger.class.getPackage().getName() + ".request.io"); so we disable io.undertow.request.io but it seems that there are still io exceptions logged as io.undertow.request, i see log entries like this: io.undertow.request 2017-06-08 23:44:14,898 UT005003: IOException reading from channel java.io.IOException: UT000128: Remote peer closed connection before all data could be read at io.undertow.conduits.FixedLengthStreamSourceConduit.exitRead(FixedLengthStreamSourceConduit.java:338) at io.undertow.conduits.FixedLengthStreamSourceConduit.read(FixedLengthStreamSourceConduit.java:255) at org.xnio.conduits.ConduitStreamSourceChannel.read(ConduitStreamSourceChannel.java:127) at io.undertow.channels.DetachableStreamSourceChannel.read(DetachableStreamSourceChannel.java:209) at io.undertow.server.HttpServerExchange$ReadDispatchChannel.read(HttpServerExchange.java:2287) at io.undertow.server.handlers.form.FormEncodedDataDefinition$FormEncodedDataParser.doParse(FormEncodedDataDefinition.java:134) at io.undertow.server.handlers.form.FormEncodedDataDefinition$FormEncodedDataParser.handleEvent(FormEncodedDataDefinition.java:115 to me it seems that the handler for form encoded post data uses the wrong logger for its io exceptions. best, sascha _______________________________________________ undertow-dev mailing list undertow-dev(a)lists.jboss.org https://lists.jboss.org/mailman/listinfo/undertow-dev
