[JBoss JIRA] Created: (JBREM-929) Secure remote classloading

by David Lloyd (JIRA)

Secure remote classloading -------------------------- Key: JBREM-929 URL: http://jira.jboss.com/jira/browse/JBREM-929 Project: JBoss Remoting Issue Type: Task Security Level: Public (Everyone can see) Reporter: David Lloyd Fix For: 3.0.0-M3 Remote classloading should be allowed only if either (a) a security manager is installed (and thus the security manager would create the policy) or (b) a specific option is enabled (which would be disabled by default) to allow it. Also, the remote classloader needs to be able to work with the standard security manager policy - which is to say, that classes loaded from a remote service need to have a unique codeBase URL so that administrators can grant permission to remote classes based on the service from whence they came. -- This message is automatically generated by JIRA. - If you think it was sent incorrectly contact one of the administrators: http://jira.jboss.com/jira/secure/Administrators.jspa - For more information on JIRA, see: http://www.atlassian.com/software/jira

[JBoss JIRA] Created: (JBREM-947) ConnectionValidator hangs when server dies

by Tim Fox (JIRA)

ConnectionValidator hangs when server dies ------------------------------------------ Key: JBREM-947 URL: http://jira.jboss.com/jira/browse/JBREM-947 Project: JBoss Remoting Issue Type: Bug Security Level: Public (Everyone can see) Reporter: Tim Fox Fix For: 2.2.2.SP7 If the connection between client and server is pulled (pull the real cable) or the entire server suddenly dies, then the connection won't be closed from the server (unlike a kill -9 of the server where the OS will terminate that processses connections), so the client making the write() or read() on the socket won't receive an exception. In the eyes of TCP the connection is still alive and the read/write will block until the socket timeout is reached. Typically the socket timeout will be much higher than the desired failure detection time (the validation interval), but currently failure will never be detected in this situation before the socket timeout time. Remoting should not be dependent on the socket timeout for failure detection, the connetion validation and socket timeout should be possible to be configured separately. E.g. you might want to configure a socket timeout of 60 seconds, but a connection validation frequency (ping) of 5 seconds. Currently this is not possible. The current implementation gives inconsistent behaviour depending on how the server died - i.e. whether the process died (e.g. kill -9) or the cable was pulled or the entire server disappeared. -- This message is automatically generated by JIRA. - If you think it was sent incorrectly contact one of the administrators: http://jira.jboss.com/jira/secure/Administrators.jspa - For more information on JIRA, see: http://www.atlassian.com/software/jira

[JBoss JIRA] Created: (JBREM-963) Work out a mechanism to handle protocol message ordering issues across multiple channels

by David Lloyd (JIRA)

Work out a mechanism to handle protocol message ordering issues across multiple channels ---------------------------------------------------------------------------------------- Key: JBREM-963 URL: http://jira.jboss.com/jira/browse/JBREM-963 Project: JBoss Remoting Issue Type: Task Security Level: Public (Everyone can see) Reporter: David Lloyd Fix For: 3.0.0-M3 When dealing with a protocol using multiple channels (HTTP for example, and possibly a future multi-channel JRPP variant), sending two messages on two different channels can cause ordering issues if the second message sent arrives first. For example, sending a context open on channel A, and a request on channel B, may cause the request to be received before the context open message, resulting in the request being rejected with a "no such context" error. Another example is that stream messages must be handled sequentially. There are several possible solutions, including but not limited to: * for any message B that must come after A, always send A and B on the same channel (problem: HTTP channels are transient, so this won't work for HTTP) (problem: this could load up one channel while leaving other channels empty, even if load-balancing is used) * don't send B until after A is acknowledged (problem: acknowledging A might not be possible within the underlying protocol, like if A is sent in an HTTP reply, requiring a separate ACK message, which can lead to performance problems) * if a message comes in seemingly unsolicited (like a request on a nonexistant context) or out of sequence (like in a stream), queue the message for some fixed amount of time to see if the context open message arrives (problem: could be a source of DoS on the server; also this is a duplication of what protocols like TCP already do, which means that all the same problems must be in effect re-solved) Starting a forum thread to discuss the topic. -- This message is automatically generated by JIRA. - If you think it was sent incorrectly contact one of the administrators: http://jira.jboss.com/jira/secure/Administrators.jspa - For more information on JIRA, see: http://www.atlassian.com/software/jira

[JBoss JIRA] Created: (JBREM-957) faulty logging: ...transport.http.ssl.HTTPSClientInvoker.createSocketFactory logs an error when there is no error

by Larry Talley (JIRA)

faulty logging: ...transport.http.ssl.HTTPSClientInvoker.createSocketFactory logs an error when there is no error ----------------------------------------------------------------------------------------------------------------- Key: JBREM-957 URL: http://jira.jboss.com/jira/browse/JBREM-957 Project: JBoss Remoting Issue Type: Bug Security Level: Public (Everyone can see) Environment: 2.2.0.GA as included in JBoss-4.2.2.GA Reporter: Larry Talley When used in client mode ...transport.http.ssl.HTTPSClientInvoker.createSocketFactory(HTTPSClientInvoker.java:140) logs an error, but then proceeds to work fine (because sf already has a valid value due to line 129). The misreported error spews misleading information in the log. I suggest that line 144 shouldn't be at ERROR level if the IOException isn't always an error. -- This message is automatically generated by JIRA. - If you think it was sent incorrectly contact one of the administrators: http://jira.jboss.com/jira/secure/Administrators.jspa - For more information on JIRA, see: http://www.atlassian.com/software/jira
