| 77 | /** |
| 78 | * This class represents a default implementation for |
| 79 | * <code>java.security.Policy</code>. |
| 80 | * |
| 81 | * Note: |
| 82 | * For backward compatibility with JAAS 1.0 it loads |
| 83 | * both java.auth.policy and java.policy. However it |
| 84 | * is recommended that java.auth.policy be not used |
| 85 | * and the java.policy contain all grant entries including |
| 86 | * that contain principal-based entries. |
| 87 | * |
| 88 | * |
| 89 | * <p> This object stores the policy for entire Java runtime, |
| 90 | * and is the amalgamation of multiple static policy |
| 91 | * configurations that resides in files. |
| 92 | * The algorithm for locating the policy file(s) and reading their |
| 93 | * information into this <code>Policy</code> object is: |
| 94 | * |
| 95 | * <ol> |
| 96 | * <li> |
| 97 | * Loop through the <code>java.security.Security</code> properties, |
| 98 | * <i>policy.url.1</i>, <i>policy.url.2</i>, ..., |
| 99 | * <i>policy.url.X</i>" and |
| 100 | * <i>auth.policy.url.1</i>, <i>auth.policy.url.2</i>, ..., |
| 101 | * <i>auth.policy.url.X</i>". These properties are set |
| 102 | * in the Java security properties file, which is located in the file named |
| 103 | * <JAVA_HOME>/lib/security/java.security. |
| 104 | * <JAVA_HOME> refers to the value of the java.home system property, |
| 105 | * and specifies the directory where the JRE is installed. |
| 106 | * Each property value specifies a <code>URL</code> pointing to a |
| 107 | * policy file to be loaded. Read in and load each policy. |
| 108 | * |
| 109 | * <i>auth.policy.url</i> is supported only for backward compatibility. |
| 110 | * |
| 111 | * <li> |
| 112 | * The <code>java.lang.System</code> property <i>java.security.policy</i> |
| 113 | * may also be set to a <code>URL</code> pointing to another policy file |
| 114 | * (which is the case when a user uses the -D switch at runtime). |
| 115 | * If this property is defined, and its use is allowed by the |
| 116 | * security property file (the Security property, |
| 117 | * <i>policy.allowSystemProperty</i> is set to <i>true</i>), |
| 118 | * also load that policy. |
| 119 | * |
| 120 | * <li> |
| 121 | * The <code>java.lang.System</code> property |
| 122 | * <i>java.security.auth.policy</i> may also be set to a |
| 123 | * <code>URL</code> pointing to another policy file |
| 124 | * (which is the case when a user uses the -D switch at runtime). |
| 125 | * If this property is defined, and its use is allowed by the |
| 126 | * security property file (the Security property, |
| 127 | * <i>policy.allowSystemProperty</i> is set to <i>true</i>), |
| 128 | * also load that policy. |
| 129 | * |
| 130 | * <i>java.security.auth.policy</i> is supported only for backward |
| 131 | * compatibility. |
| 132 | * |
| 133 | * If the <i>java.security.policy</i> or |
| 134 | * <i>java.security.auth.policy</i> property is defined using |
| 135 | * "==" (rather than "="), then ignore all other specified |
| 136 | * policies and only load this policy. |
| 137 | * </ol> |
| 138 | * |
| 139 | * Each policy file consists of one or more grant entries, each of |
| 140 | * which consists of a number of permission entries. |
| 141 | * |
| 142 | * <pre> |
| 143 | * grant signedBy "<b>alias</b>", codeBase "<b>URL</b>", |
| 144 | * principal <b>principalClass</b> "<b>principalName</b>", |
| 145 | * principal <b>principalClass</b> "<b>principalName</b>", |
| 146 | * ... { |
| 147 | * |
| 148 | * permission <b>Type</b> "<b>name</b> "<b>action</b>", |
| 149 | * signedBy "<b>alias</b>"; |
| 150 | * permission <b>Type</b> "<b>name</b> "<b>action</b>", |
| 151 | * signedBy "<b>alias</b>"; |
| 152 | * .... |
| 153 | * }; |
| 154 | * </pre> |
| 155 | * |
| 156 | * All non-bold items above must appear as is (although case |
| 157 | * doesn't matter and some are optional, as noted below). |
| 158 | * principal entries are optional and need not be present. |
| 159 | * Italicized items represent variable values. |
| 160 | * |
| 161 | * <p> A grant entry must begin with the word <code>grant</code>. |
| 162 | * The <code>signedBy</code>,<code>codeBase</code> and <code>principal</code> |
| 163 | * name/value pairs are optional. |
| 164 | * If they are not present, then any signer (including unsigned code) |
| 165 | * will match, and any codeBase will match. |
| 166 | * Note that the <i>principalClass</i> |
| 167 | * may be set to the wildcard value, *, which allows it to match |
| 168 | * any <code>Principal</code> class. In addition, the <i>principalName</i> |
| 169 | * may also be set to the wildcard value, *, allowing it to match |
| 170 | * any <code>Principal</code> name. When setting the <i>principalName</i> |
| 171 | * to the *, do not surround the * with quotes. |
| 172 | * |
| 173 | * <p> A permission entry must begin with the word <code>permission</code>. |
| 174 | * The word <code><i>Type</i></code> in the template above is |
| 175 | * a specific permission type, such as <code>java.io.FilePermission</code> |
| 176 | * or <code>java.lang.RuntimePermission</code>. |
| 177 | * |
| 178 | * <p> The "<i>action</i>" is required for |
| 179 | * many permission types, such as <code>java.io.FilePermission</code> |
| 180 | * (where it specifies what type of file access that is permitted). |
| 181 | * It is not required for categories such as |
| 182 | * <code>java.lang.RuntimePermission</code> |
| 183 | * where it is not necessary - you either have the |
| 184 | * permission specified by the <code>"<i>name</i>"</code> |
| 185 | * value following the type name or you don't. |
| 186 | * |
| 187 | * <p> The <code>signedBy</code> name/value pair for a permission entry |
| 188 | * is optional. If present, it indicates a signed permission. That is, |
| 189 | * the permission class itself must be signed by the given alias in |
| 190 | * order for it to be granted. For example, |
| 191 | * suppose you have the following grant entry: |
| 192 | * |
| 193 | * <pre> |
| 194 | * grant principal foo.com.Principal "Duke" { |
| 195 | * permission Foo "foobar", signedBy "FooSoft"; |
| 196 | * } |
| 197 | * </pre> |
| 198 | * |
| 199 | * <p> Then this permission of type <i>Foo</i> is granted if the |
| 200 | * <code>Foo.class</code> permission has been signed by the |
| 201 | * "FooSoft" alias, or if XXX <code>Foo.class</code> is a |
| 202 | * system class (i.e., is found on the CLASSPATH). |
| 203 | * |
| 204 | * |
| 205 | * <p> Items that appear in an entry must appear in the specified order |
| 206 | * (<code>permission</code>, <i>Type</i>, "<i>name</i>", and |
| 207 | * "<i>action</i>"). An entry is terminated with a semicolon. |
| 208 | * |
| 209 | * <p> Case is unimportant for the identifiers (<code>permission</code>, |
| 210 | * <code>signedBy</code>, <code>codeBase</code>, etc.) but is |
| 211 | * significant for the <i>Type</i> |
| 212 | * or for any string that is passed in as a value. <p> |
| 213 | * |
| 214 | * <p> An example of two entries in a policy configuration file is |
| 215 | * <pre> |
| 216 | * // if the code is comes from "foo.com" and is running as "Duke", |
| 217 | * // grant it read/write to all files in /tmp. |
| 218 | * |
| 219 | * grant codeBase "foo.com", principal foo.com.Principal "Duke" { |
| 220 | * permission java.io.FilePermission "/tmp/*", "read,write"; |
| 221 | * }; |
| 222 | * |
| 223 | * // grant any code running as "Duke" permission to read |
| 224 | * // the "java.vendor" Property. |
| 225 | * |
| 226 | * grant principal foo.com.Principal "Duke" { |
| 227 | * permission java.util.PropertyPermission "java.vendor"; |
| 228 | * |
| 229 | * |
| 230 | * </pre> |
| 231 | * This Policy implementation supports special handling of any |
| 232 | * permission that contains the string, "<b>${{self}}</b>", as part of |
| 233 | * its target name. When such a permission is evaluated |
| 234 | * (such as during a security check), <b>${{self}}</b> is replaced |
| 235 | * with one or more Principal class/name pairs. The exact |
| 236 | * replacement performed depends upon the contents of the |
| 237 | * grant clause to which the permission belongs. |
| 238 | *<p> |
| 239 | * |
| 240 | * If the grant clause does not contain any principal information, |
| 241 | * the permission will be ignored (permissions containing |
| 242 | * <b>${{self}}</b> in their target names are only valid in the context |
| 243 | * of a principal-based grant clause). For example, BarPermission |
| 244 | * will always be ignored in the following grant clause: |
| 245 | * |
| 246 | *<pre> |
| 247 | * grant codebase "www.foo.com", signedby "duke" { |
| 248 | * permission BarPermission "... ${{self}} ..."; |
| 249 | * }; |
| 250 | *</pre> |
| 251 | * |
| 252 | * If the grant clause contains principal information, <b>${{self}}</b> |
| 253 | * will be replaced with that same principal information. |
| 254 | * For example, <b>${{self}}</b> in BarPermission will be replaced by |
| 255 | * <b>javax.security.auth.x500.X500Principal "cn=Duke"</b> |
| 256 | * in the following grant clause: |
| 257 | * |
| 258 | * <pre> |
| 259 | * grant principal javax.security.auth.x500.X500Principal "cn=Duke" { |
| 260 | * permission BarPermission "... ${{self}} ..."; |
| 261 | * }; |
| 262 | * </pre> |
| 263 | * |
| 264 | * If there is a comma-separated list of principals in the grant |
| 265 | * clause, then <b>${{self}}</b> will be replaced by the same |
| 266 | * comma-separated list or principals. |
| 267 | * In the case where both the principal class and name are |
| 268 | * wildcarded in the grant clause, <b>${{self}}</b> is replaced |
| 269 | * with all the principals associated with the <code>Subject</code> |
| 270 | * in the current <code>AccessControlContext</code>. |
| 271 | * |
| 272 | * |
| 273 | * <p> For PrivateCredentialPermissions, you can also use "<b>self</b>" |
| 274 | * instead of "<b>${{self}}</b>". However the use of "<b>self</b>" is |
| 275 | * deprecated in favour of "<b>${{self}}</b>". |
