| 53 | /** | ||
| 54 | * This class represents a default implementation for | ||
| 55 | * <code>javax.security.auth.Policy</code>. | ||
| 56 | * | ||
| 57 | * <p> This object stores the policy for entire Java runtime, | ||
| 58 | * and is the amalgamation of multiple static policy | ||
| 59 | * configurations that resides in files. | ||
| 60 | * The algorithm for locating the policy file(s) and reading their | ||
| 61 | * information into this <code>Policy</code> object is: | ||
| 62 | * | ||
| 63 | * <ol> | ||
| 64 | * <li> | ||
| 65 | * Loop through the <code>java.security.Security</code> properties, | ||
| 66 | * <i>auth.policy.url.1</i>, <i>auth.policy.url.2</i>, ..., | ||
| 67 | * <i>auth.policy.url.X</i>". These properties are set | ||
| 68 | * in the Java security properties file, which is located in the file named | ||
| 69 | * <JAVA_HOME>/lib/security/java.security. | ||
| 70 | * <JAVA_HOME> refers to the value of the java.home system property, | ||
| 71 | * and specifies the directory where the JRE is installed. | ||
| 72 | * Each property value specifies a <code>URL</code> pointing to a | ||
| 73 | * policy file to be loaded. Read in and load each policy. | ||
| 74 | * | ||
| 75 | * <li> | ||
| 76 | * The <code>java.lang.System</code> property <i>java.security.auth.policy</i> | ||
| 77 | * may also be set to a <code>URL</code> pointing to another policy file | ||
| 78 | * (which is the case when a user uses the -D switch at runtime). | ||
| 79 | * If this property is defined, and its use is allowed by the | ||
| 80 | * security property file (the Security property, | ||
| 81 | * <i>policy.allowSystemProperty</i> is set to <i>true</i>), | ||
| 82 | * also load that policy. | ||
| 83 | * | ||
| 84 | * <li> | ||
| 85 | * If the <i>java.security.auth.policy</i> property is defined using | ||
| 86 | * "==" (rather than "="), then ignore all other specified | ||
| 87 | * policies and only load this policy. | ||
| 88 | * </ol> | ||
| 89 | * | ||
| 90 | * Each policy file consists of one or more grant entries, each of | ||
| 91 | * which consists of a number of permission entries. | ||
| 92 | * | ||
| 93 | * <pre> | ||
| 94 | * grant signedBy "<b>alias</b>", codeBase "<b>URL</b>", | ||
| 95 | * principal <b>principalClass</b> "<b>principalName</b>", | ||
| 96 | * principal <b>principalClass</b> "<b>principalName</b>", | ||
| 97 | * ... { | ||
| 98 | * | ||
| 99 | * permission <b>Type</b> "<b>name</b> "<b>action</b>", | ||
| 100 | * signedBy "<b>alias</b>"; | ||
| 101 | * permission <b>Type</b> "<b>name</b> "<b>action</b>", | ||
| 102 | * signedBy "<b>alias</b>"; | ||
| 103 | * .... | ||
| 104 | * }; | ||
| 105 | * </pre> | ||
| 106 | * | ||
| 107 | * All non-bold items above must appear as is (although case | ||
| 108 | * doesn't matter and some are optional, as noted below). | ||
| 109 | * Italicized items represent variable values. | ||
| 110 | * | ||
| 111 | * <p> A grant entry must begin with the word <code>grant</code>. | ||
| 112 | * The <code>signedBy</code> and <code>codeBase</code> | ||
| 113 | * name/value pairs are optional. | ||
| 114 | * If they are not present, then any signer (including unsigned code) | ||
| 115 | * will match, and any codeBase will match. Note that the | ||
| 116 | * <code>principal</code> name/value pair is not optional. | ||
| 117 | * This <code>Policy</code> implementation only permits | ||
| 118 | * Principal-based grant entries. Note that the <i>principalClass</i> | ||
| 119 | * may be set to the wildcard value, *, which allows it to match | ||
| 120 | * any <code>Principal</code> class. In addition, the <i>principalName</i> | ||
| 121 | * may also be set to the wildcard value, *, allowing it to match | ||
| 122 | * any <code>Principal</code> name. When setting the <i>principalName</i> | ||
| 123 | * to the *, do not surround the * with quotes. | ||
| 124 | * | ||
| 125 | * <p> A permission entry must begin with the word <code>permission</code>. | ||
| 126 | * The word <code><i>Type</i></code> in the template above is | ||
| 127 | * a specific permission type, such as <code>java.io.FilePermission</code> | ||
| 128 | * or <code>java.lang.RuntimePermission</code>. | ||
| 129 | * | ||
| 130 | * <p> The "<i>action</i>" is required for | ||
| 131 | * many permission types, such as <code>java.io.FilePermission</code> | ||
| 132 | * (where it specifies what type of file access that is permitted). | ||
| 133 | * It is not required for categories such as | ||
| 134 | * <code>java.lang.RuntimePermission</code> | ||
| 135 | * where it is not necessary - you either have the | ||
| 136 | * permission specified by the <code>"<i>name</i>"</code> | ||
| 137 | * value following the type name or you don't. | ||
| 138 | * | ||
| 139 | * <p> The <code>signedBy</code> name/value pair for a permission entry | ||
| 140 | * is optional. If present, it indicates a signed permission. That is, | ||
| 141 | * the permission class itself must be signed by the given alias in | ||
| 142 | * order for it to be granted. For example, | ||
| 143 | * suppose you have the following grant entry: | ||
| 144 | * | ||
| 145 | * <pre> | ||
| 146 | * grant principal foo.com.Principal "Duke" { | ||
| 147 | * permission Foo "foobar", signedBy "FooSoft"; | ||
| 148 | * } | ||
| 149 | * </pre> | ||
| 150 | * | ||
| 151 | * <p> Then this permission of type <i>Foo</i> is granted if the | ||
| 152 | * <code>Foo.class</code> permission has been signed by the | ||
| 153 | * "FooSoft" alias, or if <code>Foo.class</code> is a | ||
| 154 | * system class (i.e., is found on the CLASSPATH). | ||
| 155 | * | ||
| 156 | * <p> Items that appear in an entry must appear in the specified order | ||
| 157 | * (<code>permission</code>, <i>Type</i>, "<i>name</i>", and | ||
| 158 | * "<i>action</i>"). An entry is terminated with a semicolon. | ||
| 159 | * | ||
| 160 | * <p> Case is unimportant for the identifiers (<code>permission</code>, | ||
| 161 | * <code>signedBy</code>, <code>codeBase</code>, etc.) but is | ||
| 162 | * significant for the <i>Type</i> | ||
| 163 | * or for any string that is passed in as a value. <p> | ||
| 164 | * | ||
| 165 | * <p> An example of two entries in a policy configuration file is | ||
| 166 | * <pre> | ||
| 167 | * // if the code is comes from "foo.com" and is running as "Duke", | ||
| 168 | * // grant it read/write to all files in /tmp. | ||
| 169 | * | ||
| 170 | * grant codeBase "foo.com", principal foo.com.Principal "Duke" { | ||
| 171 | * permission java.io.FilePermission "/tmp/*", "read,write"; | ||
| 172 | * }; | ||
| 173 | * | ||
| 174 | * // grant any code running as "Duke" permission to read | ||
| 175 | * // the "java.vendor" Property. | ||
| 176 | * | ||
| 177 | * grant principal foo.com.Principal "Duke" { | ||
| 178 | * permission java.util.PropertyPermission "java.vendor"; | ||
| 179 | * </pre> | ||
| 180 | * | ||
| 181 | * <p> This <code>Policy</code> implementation supports | ||
| 182 | * special handling for PrivateCredentialPermissions. | ||
| 183 | * If a grant entry is configured with a | ||
| 184 | * <code>PrivateCredentialPermission</code>, | ||
| 185 | * and the "Principal Class/Principal Name" for that | ||
| 186 | * <code>PrivateCredentialPermission</code> is "self", | ||
| 187 | * then the entry grants the specified <code>Subject</code> permission to | ||
| 188 | * access its own private Credential. For example, | ||
| 189 | * the following grants the <code>Subject</code> "Duke" | ||
| 190 | * access to its own a.b.Credential. | ||
| 191 | * | ||
| 192 | * <pre> | ||
| 193 | * grant principal foo.com.Principal "Duke" { | ||
| 194 | * permission javax.security.auth.PrivateCredentialPermission | ||
| 195 | * "a.b.Credential self", | ||
| 196 | * "read"; | ||
| 197 | * }; | ||
| 198 | * </pre> | ||
| 199 | * | ||
| 200 | * The following grants the <code>Subject</code> "Duke" | ||
| 201 | * access to all of its own private Credentials: | ||
| 202 | * | ||
| 203 | * <pre> | ||
| 204 | * grant principal foo.com.Principal "Duke" { | ||
| 205 | * permission javax.security.auth.PrivateCredentialPermission | ||
| 206 | * "* self", | ||
| 207 | * "read"; | ||
| 208 | * }; | ||
| 209 | * </pre> | ||
| 210 | * | ||
| 211 | * The following grants all Subjects authenticated as a | ||
| 212 | * <code>SolarisPrincipal</code> (regardless of their respective names) | ||
| 213 | * permission to access their own private Credentials: | ||
| 214 | * | ||
| 215 | * <pre> | ||
| 216 | * grant principal com.sun.security.auth.SolarisPrincipal * { | ||
| 217 | * permission javax.security.auth.PrivateCredentialPermission | ||
| 218 | * "* self", | ||
| 219 | * "read"; | ||
| 220 | * }; | ||
| 221 | * </pre> | ||
| 222 | * | ||
| 223 | * The following grants all Subjects permission to access their own | ||
| 224 | * private Credentials: | ||
| 225 | * | ||
| 226 | * <pre> | ||
| 227 | * grant principal * * { | ||
| 228 | * permission javax.security.auth.PrivateCredentialPermission | ||
| 229 | * "* self", | ||
| 230 | * "read"; | ||
