From 1194cd0bdc22bc598a936480437951e7b130b1d7 Mon Sep 17 00:00:00 2001 From: Robert Muir Date: Thu, 29 Oct 2015 14:14:27 -0400 Subject: [PATCH] Add threadgroup isolation. Closes #14353 Squashed commit of the following: commit edae0729f71ea3d3f9fa9c0d27c9effc042eb5a9 Author: Robert Muir Date: Thu Oct 29 14:13:42 2015 -0400 update sha1 and simplify test commit 635c4f245d66ad353a16267c810e02b725553fad Author: Robert Muir Date: Thu Oct 29 07:01:26 2015 -0400 Add threadgroup isolation. Code with `modifyThread` and `modifyThreadGroup` may only modify its own threadgroup (or an ancestor of that). This enforces what is intended by the ThreadGroup class. This has two immediate implications: 1. Code without these permissions (scripts) may not create or mess with threads 2. ES application threads cannot mess with Java system threads ES puts all application threads in one single group today, but in the future this can be organized better, and we will have more isolation in the system. --- core/pom.xml | 4 + .../org/elasticsearch/bootstrap/Security.java | 12 +- .../elasticsearch/bootstrap/security.policy | 12 +- .../bootstrap/test-framework.policy | 2 +- .../bootstrap/BootstrapForTesting.java | 3 +- distribution/licenses/securesm-1.0.jar.sha1 | 1 + distribution/licenses/securesm-LICENSE.txt | 202 ++++++++++++++++++ distribution/licenses/securesm-NOTICE.txt | 2 + .../script/groovy/GroovySecurityTests.java | 3 + pom.xml | 7 + 10 files changed, 234 insertions(+), 14 deletions(-) create mode 100644 distribution/licenses/securesm-1.0.jar.sha1 create mode 100644 distribution/licenses/securesm-LICENSE.txt create mode 100644 distribution/licenses/securesm-NOTICE.txt diff --git a/core/pom.xml b/core/pom.xml index bc871f79963..26a37db5a34 100644 --- a/core/pom.xml +++ b/core/pom.xml @@ -104,6 +104,10 @@ + + org.elasticsearch + securesm + com.carrotsearch hppc diff --git a/core/src/main/java/org/elasticsearch/bootstrap/Security.java b/core/src/main/java/org/elasticsearch/bootstrap/Security.java index cb55981968a..dcb7bafb91e 100644 --- a/core/src/main/java/org/elasticsearch/bootstrap/Security.java +++ b/core/src/main/java/org/elasticsearch/bootstrap/Security.java @@ -19,6 +19,7 @@ package org.elasticsearch.bootstrap;
