Subject [jira] [Comment Edited] (DERBY-6438) Explicitly grant SocketPermission "listen" in default server policy
Date Wed, 22 Jan 2014 21:50:23 GMT

    [ https://issues.apache.org/jira/browse/DERBY-6438?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13879223#comment-13879223

----------------------------------------------------------------

I also agree we should put out a single server policy file in 10.10 that works for as many
jvms as possible.  If policy files allow, it would be nice to add a comment in the file noting
the param is new for jdk18 and above but should be ok to include when using releases previous
to jdk18 and will have no affect (i assume).  This will be good to get into the upcoming 10.10
apache release will be targeted at full support of jdk18 when it is actually released.

the question for those of us wanting to support the newest pre-jdk18 releases coming from
oracle now (and from dependent vendors in the near future) on derby releases prior to 10.10,
is what exactly do we need to backport to address this new issue.

> The network server needs SocketPermission "listen" on the port that it listens to, but
this permission is not granted by the basic server policy that's installed by default. This
doesn't cause any problems in most cases, since the JVM's default policy grants all code bases
SocketPermission "listen" on a range of ports, and Derby's network server port is within that
range.
> Still, the network server should not rely on this fact. It is possible to run the network
server on any port, not only those ports that happen be in the range that's given carte blanche
by the platform's default policy. The network server will however not be able to run on those
ports with the basic policy currently, only with a custom policy or with the security manager
disabled.
> The default policy should make this permission explicit.
