| 79 | /** | ||
| 80 | * This class represents a default implementation for | ||
| 81 | * <code>java.security.Policy</code>. | ||
| 82 | * | ||
| 83 | * Note: | ||
| 84 | * For backward compatibility with JAAS 1.0 it loads | ||
| 85 | * both java.auth.policy and java.policy. However it | ||
| 86 | * is recommended that java.auth.policy be not used | ||
| 87 | * and the java.policy contain all grant entries including | ||
| 88 | * that contain principal-based entries. | ||
| 89 | * | ||
| 90 | * | ||
| 91 | * <p> This object stores the policy for entire Java runtime, | ||
| 92 | * and is the amalgamation of multiple static policy | ||
| 93 | * configurations that resides in files. | ||
| 94 | * The algorithm for locating the policy file(s) and reading their | ||
| 95 | * information into this <code>Policy</code> object is: | ||
| 96 | * | ||
| 97 | * <ol> | ||
| 98 | * <li> | ||
| 99 | * Loop through the <code>java.security.Security</code> properties, | ||
| 100 | * <i>policy.url.1</i>, <i>policy.url.2</i>, ..., | ||
| 101 | * <i>policy.url.X</i>" and | ||
| 102 | * <i>auth.policy.url.1</i>, <i>auth.policy.url.2</i>, ..., | ||
| 103 | * <i>auth.policy.url.X</i>". These properties are set | ||
| 104 | * in the Java security properties file, which is located in the file named | ||
| 105 | * <JAVA_HOME>/lib/security/java.security. | ||
| 106 | * <JAVA_HOME> refers to the value of the java.home system property, | ||
| 107 | * and specifies the directory where the JRE is installed. | ||
| 108 | * Each property value specifies a <code>URL</code> pointing to a | ||
| 109 | * policy file to be loaded. Read in and load each policy. | ||
| 110 | * | ||
| 111 | * <i>auth.policy.url</i> is supported only for backward compatibility. | ||
| 112 | * | ||
| 113 | * <li> | ||
| 114 | * The <code>java.lang.System</code> property <i>java.security.policy</i> | ||
| 115 | * may also be set to a <code>URL</code> pointing to another policy file | ||
| 116 | * (which is the case when a user uses the -D switch at runtime). | ||
| 117 | * If this property is defined, and its use is allowed by the | ||
| 118 | * security property file (the Security property, | ||
| 119 | * <i>policy.allowSystemProperty</i> is set to <i>true</i>), | ||
| 120 | * also load that policy. | ||
| 121 | * | ||
| 122 | * <li> | ||
| 123 | * The <code>java.lang.System</code> property | ||
| 124 | * <i>java.security.auth.policy</i> may also be set to a | ||
| 125 | * <code>URL</code> pointing to another policy file | ||
| 126 | * (which is the case when a user uses the -D switch at runtime). | ||
| 127 | * If this property is defined, and its use is allowed by the | ||
| 128 | * security property file (the Security property, | ||
| 129 | * <i>policy.allowSystemProperty</i> is set to <i>true</i>), | ||
| 130 | * also load that policy. | ||
| 131 | * | ||
| 132 | * <i>java.security.auth.policy</i> is supported only for backward | ||
| 133 | * compatibility. | ||
| 134 | * | ||
| 135 | * If the <i>java.security.policy</i> or | ||
| 136 | * <i>java.security.auth.policy</i> property is defined using | ||
| 137 | * "==" (rather than "="), then ignore all other specified | ||
| 138 | * policies and only load this policy. | ||
| 139 | * </ol> | ||
| 140 | * | ||
| 141 | * Each policy file consists of one or more grant entries, each of | ||
| 142 | * which consists of a number of permission entries. | ||
| 143 | * | ||
| 144 | * <pre> | ||
| 145 | * grant signedBy "<b>alias</b>", codeBase "<b>URL</b>", | ||
| 146 | * principal <b>principalClass</b> "<b>principalName</b>", | ||
| 147 | * principal <b>principalClass</b> "<b>principalName</b>", | ||
| 148 | * ... { | ||
| 149 | * | ||
| 150 | * permission <b>Type</b> "<b>name</b> "<b>action</b>", | ||
| 151 | * signedBy "<b>alias</b>"; | ||
| 152 | * permission <b>Type</b> "<b>name</b> "<b>action</b>", | ||
| 153 | * signedBy "<b>alias</b>"; | ||
| 154 | * .... | ||
| 155 | * }; | ||
| 156 | * </pre> | ||
| 157 | * | ||
| 158 | * All non-bold items above must appear as is (although case | ||
| 159 | * doesn't matter and some are optional, as noted below). | ||
| 160 | * principal entries are optional and need not be present. | ||
| 161 | * Italicized items represent variable values. | ||
| 162 | * | ||
| 163 | * <p> A grant entry must begin with the word <code>grant</code>. | ||
| 164 | * The <code>signedBy</code>,<code>codeBase</code> and <code>principal</code> | ||
| 165 | * name/value pairs are optional. | ||
| 166 | * If they are not present, then any signer (including unsigned code) | ||
| 167 | * will match, and any codeBase will match. | ||
| 168 | * Note that the <i>principalClass</i> | ||
| 169 | * may be set to the wildcard value, *, which allows it to match | ||
| 170 | * any <code>Principal</code> class. In addition, the <i>principalName</i> | ||
| 171 | * may also be set to the wildcard value, *, allowing it to match | ||
| 172 | * any <code>Principal</code> name. When setting the <i>principalName</i> | ||
| 173 | * to the *, do not surround the * with quotes. | ||
| 174 | * | ||
| 175 | * <p> A permission entry must begin with the word <code>permission</code>. | ||
| 176 | * The word <code><i>Type</i></code> in the template above is | ||
| 177 | * a specific permission type, such as <code>java.io.FilePermission</code> | ||
| 178 | * or <code>java.lang.RuntimePermission</code>. | ||
| 179 | * | ||
| 180 | * <p> The "<i>action</i>" is required for | ||
| 181 | * many permission types, such as <code>java.io.FilePermission</code> | ||
| 182 | * (where it specifies what type of file access that is permitted). | ||
| 183 | * It is not required for categories such as | ||
| 184 | * <code>java.lang.RuntimePermission</code> | ||
| 185 | * where it is not necessary - you either have the | ||
| 186 | * permission specified by the <code>"<i>name</i>"</code> | ||
| 187 | * value following the type name or you don't. | ||
| 188 | * | ||
| 189 | * <p> The <code>signedBy</code> name/value pair for a permission entry | ||
| 190 | * is optional. If present, it indicates a signed permission. That is, | ||
| 191 | * the permission class itself must be signed by the given alias in | ||
| 192 | * order for it to be granted. For example, | ||
| 193 | * suppose you have the following grant entry: | ||
| 194 | * | ||
| 195 | * <pre> | ||
| 196 | * grant principal foo.com.Principal "Duke" { | ||
| 197 | * permission Foo "foobar", signedBy "FooSoft"; | ||
| 198 | * } | ||
| 199 | * </pre> | ||
| 200 | * | ||
| 201 | * <p> Then this permission of type <i>Foo</i> is granted if the | ||
| 202 | * <code>Foo.class</code> permission has been signed by the | ||
| 203 | * "FooSoft" alias, or if XXX <code>Foo.class</code> is a | ||
| 204 | * system class (i.e., is found on the CLASSPATH). | ||
| 205 | * | ||
| 206 | * | ||
| 207 | * <p> Items that appear in an entry must appear in the specified order | ||
| 208 | * (<code>permission</code>, <i>Type</i>, "<i>name</i>", and | ||
| 209 | * "<i>action</i>"). An entry is terminated with a semicolon. | ||
| 210 | * | ||
| 211 | * <p> Case is unimportant for the identifiers (<code>permission</code>, | ||
| 212 | * <code>signedBy</code>, <code>codeBase</code>, etc.) but is | ||
| 213 | * significant for the <i>Type</i> | ||
| 214 | * or for any string that is passed in as a value. <p> | ||
| 215 | * | ||
| 216 | * <p> An example of two entries in a policy configuration file is | ||
| 217 | * <pre> | ||
| 218 | * // if the code is comes from "foo.com" and is running as "Duke", | ||
| 219 | * // grant it read/write to all files in /tmp. | ||
| 220 | * | ||
| 221 | * grant codeBase "foo.com", principal foo.com.Principal "Duke" { | ||
| 222 | * permission java.io.FilePermission "/tmp/*", "read,write"; | ||
| 223 | * }; | ||
| 224 | * | ||
| 225 | * // grant any code running as "Duke" permission to read | ||
| 226 | * // the "java.vendor" Property. | ||
| 227 | * | ||
| 228 | * grant principal foo.com.Principal "Duke" { | ||
| 229 | * permission java.util.PropertyPermission "java.vendor"; | ||
| 230 | * | ||
| 231 | * | ||
| 232 | * </pre> | ||
| 233 | * This Policy implementation supports special handling of any | ||
| 234 | * permission that contains the string, "<b>${{self}}</b>", as part of | ||
| 235 | * its target name. When such a permission is evaluated | ||
| 236 | * (such as during a security check), <b>${{self}}</b> is replaced | ||
| 237 | * with one or more Principal class/name pairs. The exact | ||
| 238 | * replacement performed depends upon the contents of the | ||
| 239 | * grant clause to which the permission belongs. | ||
| 240 | *<p> | ||
| 241 | * | ||
| 242 | * If the grant clause does not contain any principal information, | ||
| 243 | * the permission will be ignored (permissions containing | ||
| 244 | * <b>${{self}}</b> in their target names are only valid in the context | ||
| 245 | * of a principal-based grant clause). For example, BarPermission | ||
| 246 | * will always be ignored in the following grant clause: | ||
| 247 | * | ||
| 248 | *<pre> | ||
| 249 | * grant codebase "www.foo.com", signedby "duke" { | ||
| 250 | * permission BarPermission "... ${{self}} ..."; | ||
| 251 | * }; | ||
| 252 | *</pre> | ||
| 253 | * | ||
| 254 | * If the grant clause contains principal information, <b>${{self}}</b> | ||
| 255 | * will be replaced with that same principal information. | ||
| 256 | * For example, <b>${{self}}</b> in BarPermission will be replaced by | ||
| 257 | * <b>javax.security.auth.x500.X500Principal "cn=Duke"</b> | ||
| 258 | * in the following grant clause: | ||
| 259 | * | ||
| 260 | * <pre> | ||
| 261 | * grant principal javax.security.auth.x500.X500Principal "cn=Duke" { | ||
| 262 | * permission BarPermission "... ${{self}} ..."; | ||
| 263 | * }; | ||
| 264 | * </pre> | ||
| 265 | * | ||
| 266 | * If there is a comma-separated list of principals in the grant | ||
| 267 | * clause, then <b>${{self}}</b> will be replaced by the same | ||
| 268 | * comma-separated list or principals. | ||
| 269 | * In the case where both the principal class and name are | ||
| 270 | * wildcarded in the grant clause, <b>${{self}}</b> is replaced | ||
| 271 | * with all the principals associated with the <code>Subject</code> | ||
| 272 | * in the current <code>AccessControlContext</code>. | ||
| 273 | * | ||
| 274 | * | ||
| 275 | * <p> For PrivateCredentialPermissions, you can also use "<b>self</b>" | ||
| 276 | * instead of "<b>${{self}}</b>". However the use of "<b>self</b>" is | ||
| 277 | * deprecated in favour of "<b>${{self}}</b>". | ||
