123 * struct security_operations - main security structure
125 * Security hooks for program execution operations.
127 * @bprm_alloc_security:
128 * Allocate and attach a security structure to the @bprm->security field.
129 * The security field is initialized to NULL when the bprm structure is
131 * @bprm contains the linux_binprm structure to be modified.
132 * Return 0 if operation was successful.
133 * @bprm_free_security:
134 * @bprm contains the linux_binprm structure to be modified.
135 * Deallocate and clear the @bprm->security field.
137 * Compute and set the security attributes of a process being transformed
138 * by an execve operation based on the old attributes (current->security)
139 * and the information saved in @bprm->security by the set_security hook.
140 * Since this hook function (and its caller) are void, this hook can not
141 * return an error. However, it can leave the security attributes of the
142 * process unchanged if an access failure occurs at this point.
143 * bprm_apply_creds is called under task_lock. @unsafe indicates various
144 * reasons why it may be unsafe to change security state.
145 * @bprm contains the linux_binprm structure.
146 * @bprm_post_apply_creds:
147 * Runs after bprm_apply_creds with the task_lock dropped, so that
148 * functions which cannot be called safely under the task_lock can
149 * be used. This hook is a good place to perform state changes on
150 * the process such as closing open file descriptors to which access
151 * is no longer granted if the attributes were changed.
152 * Note that a security module might need to save state between
153 * bprm_apply_creds and bprm_post_apply_creds to store the decision
154 * on whether the process may proceed.
155 * @bprm contains the linux_binprm structure.
156 * @bprm_set_security:
157 * Save security information in the bprm->security field, typically based
158 * on information about the bprm->file, for later use by the apply_creds
159 * hook. This hook may also optionally check permissions (e.g. for
160 * transitions between security domains).
161 * This hook may be called multiple times during a single execve, e.g. for
162 * interpreters. The hook can tell whether it has already been called by
163 * checking to see if @bprm->security is non-NULL. If so, then the hook
164 * may decide either to retain the security information saved earlier or
166 * @bprm contains the linux_binprm structure.
167 * Return 0 if the hook is successful and permission is granted.
168 * @bprm_check_security:
169 * This hook mediates the point when a search for a binary handler will
170 * begin. It allows a check the @bprm->security value which is set in
171 * the preceding set_security call. The primary difference from
172 * set_security is that the argv list and envp list are reliably
173 * available in @bprm. This hook may be called multiple times
174 * during a single execve; and in each pass set_security is called
176 * @bprm contains the linux_binprm structure.
177 * Return 0 if the hook is successful and permission is granted.
179 * Return a boolean value (0 or 1) indicating whether a "secure exec"
180 * is required. The flag is passed in the auxiliary table
181 * on the initial stack to the ELF interpreter to indicate whether libc
182 * should enable secure mode.
183 * @bprm contains the linux_binprm structure.
185 * Security hooks for filesystem operations.
187 * @sb_alloc_security:
188 * Allocate and attach a security structure to the sb->s_security field.
189 * The s_security field is initialized to NULL when the structure is
191 * @sb contains the super_block structure to be modified.
192 * Return 0 if operation was successful.
194 * Deallocate and clear the sb->s_security field.
195 * @sb contains the super_block structure to be modified.
197 * Check permission before obtaining filesystem statistics for the @mnt
199 * @dentry is a handle on the superblock for the filesystem.
200 * Return 0 if permission is granted.
202 * Check permission before an object specified by @dev_name is mounted on
203 * the mount point named by @nd. For an ordinary mount, @dev_name
204 * identifies a device if the file system type requires a device. For a
205 * remount (@flags & MS_REMOUNT), @dev_name is irrelevant. For a
206 * loopback/bind mount (@flags & MS_BIND), @dev_name identifies the
207 * pathname of the object being mounted.
208 * @dev_name contains the name for object being mounted.
209 * @nd contains the nameidata structure for mount point object.
210 * @type contains the filesystem type.
211 * @flags contains the mount flags.
212 * @data contains the filesystem-specific data.
213 * Return 0 if permission is granted.
215 * Allow mount option data to be copied prior to parsing by the filesystem,
216 * so that the security module can extract security-specific mount
217 * options cleanly (a filesystem may modify the data e.g. with strsep()).
218 * This also allows the original mount data to be stripped of security-
219 * specific options to avoid having to make filesystems aware of them.
220 * @type the type of filesystem being mounted.
221 * @orig the original mount data copied from userspace.
222 * @copy copied data which will be passed to the security module.
223 * Returns 0 if the copy was successful.
225 * Check permission before the device with superblock @mnt->sb is mounted
226 * on the mount point named by @nd.
227 * @mnt contains the vfsmount for device being mounted.
228 * @nd contains the nameidata object for the mount point.
229 * Return 0 if permission is granted.
231 * Check permission before the @mnt file system is unmounted.
232 * @mnt contains the mounted file system.
233 * @flags contains the unmount flags, e.g. MNT_FORCE.
234 * Return 0 if permission is granted.
236 * Close any files in the @mnt mounted filesystem that are held open by
237 * the security module. This hook is called during an umount operation
238 * prior to checking whether the filesystem is still busy.
239 * @mnt contains the mounted filesystem.
241 * Handle a failed umount of the @mnt mounted filesystem, e.g. re-opening
242 * any files that were closed by umount_close. This hook is called during
243 * an umount operation if the umount fails after a call to the
245 * @mnt contains the mounted filesystem.
247 * Update the security module's state when a filesystem is remounted.
248 * This hook is only called if the remount was successful.
249 * @mnt contains the mounted file system.
250 * @flags contains the new filesystem flags.
251 * @data contains the filesystem-specific data.
253 * Update the security module's state when a filesystem is mounted.
254 * This hook is called any time a mount is successfully grafetd to
256 * @mnt contains the mounted filesystem.
257 * @mountpoint_nd contains the nameidata structure for the mount point.
259 * Check permission before pivoting the root filesystem.
260 * @old_nd contains the nameidata structure for the new location of the current root (put_old).
261 * @new_nd contains the nameidata structure for the new root (new_root).
262 * Return 0 if permission is granted.
263 * @sb_post_pivotroot:
264 * Update module state after a successful pivot.
265 * @old_nd contains the nameidata structure for the old root.
266 * @new_nd contains the nameidata structure for the new root.
268 * Get the security relevant mount options used for a superblock
269 * @sb the superblock to get security mount options from

278 * @num_opts number of options in the arrays
279 * @sb_clone_mnt_opts:
280 * Copy all security options from a given superblock to another
281 * @oldsb old superblock which contain information to clone
282 * @newsb new superblock which needs filled in
284 * Security hooks for inode operations.
286 * @inode_alloc_security:
287 * Allocate and attach a security structure to @inode->i_security. The
288 * i_security field is initialized to NULL when the inode structure is
290 * @inode contains the inode structure.
291 * Return 0 if operation was successful.
292 * @inode_free_security:
293 * @inode contains the inode structure.
294 * Deallocate the inode security structure and set @inode->i_security to
296 * @inode_init_security:
297 * Obtain the security attribute name suffix and value to set on a newly
298 * created inode and set up the incore security field for the new inode.
299 * This hook is called by the fs code as part of the inode creation
300 * transaction and provides for atomic labeling of the inode, unlike
301 * the post_create/mkdir/... hooks called by the VFS. The hook function
302 * is expected to allocate the name and value via kmalloc, with the caller
303 * being responsible for calling kfree after using them.
304 * If the security module does not use security attributes or does
305 * not wish to put a security attribute on this particular inode,
306 * then it should return -EOPNOTSUPP to skip this processing.
307 * @inode contains the inode structure of the newly created inode.
308 * @dir contains the inode structure of the parent directory.
309 * @name will be set to the allocated name suffix (e.g. selinux).
310 * @value will be set to the allocated attribute value.
311 * @len will be set to the length of the value.
312 * Returns 0 if @name and @value have been successfully set,

324 * @dir contains the inode structure of the parent directory of the new link.
325 * @new_dentry contains the dentry structure for the new link.
326 * Return 0 if permission is granted.
328 * Check the permission to remove a hard link to a file.
329 * @dir contains the inode structure of parent directory of the file.
330 * @dentry contains the dentry structure for file to be unlinked.
331 * Return 0 if permission is granted.
333 * Check the permission to create a symbolic link to a file.
334 * @dir contains the inode structure of parent directory of the symbolic link.
335 * @dentry contains the dentry structure of the symbolic link.

349 * Return 0 if permission is granted.
351 * Check permissions when creating a special file (or a socket or a fifo
352 * file created via the mknod system call). Note that if mknod operation
353 * is being done for a regular file, then the create hook will be called
355 * @dir contains the inode structure of parent of the new file.
356 * @dentry contains the dentry structure of the new file.
357 * @mode contains the mode of the new file.
358 * @dev contains the device number.

385 * @nd contains the nameidata (may be NULL).
386 * Return 0 if permission is granted.

425 * @inode_getsecurity:
426 * Retrieve a copy of the extended attribute representation of the
427 * security label associated with @name for @inode via @buffer. Note that
428 * @name is the remainder of the attribute name after the security prefix
429 * has been removed. @alloc is used to specify of the call should return a
430 * value via the buffer or just the value length Return size of buffer on
432 * @inode_setsecurity:
433 * Set the security label associated with @name for @inode from the
434 * extended attribute value @value. @size indicates the size of the
435 * @value in bytes. @flags may be XATTR_CREATE, XATTR_REPLACE, or 0.
436 * Note that @name is the remainder of the attribute name after the
437 * security. prefix has been removed.
438 * Return 0 on success.
439 * @inode_listsecurity:
440 * Copy the extended attribute names for the security labels
441 * associated with @inode into @buffer. The maximum size of @buffer
442 * is specified by @buffer_size. @buffer may be NULL to request

444 * Returns number of bytes used/required on success.
445 * @inode_need_killpriv:
446 * Called when an inode has been changed.
447 * @dentry is the dentry being changed.
448 * Return <0 on error to abort the inode change operation.

450 * Return >0 if inode_killpriv does need to be called.
452 * The setuid bit is being removed. Remove similar security labels.
453 * Called with the dentry->d_inode->i_mutex held.

456 * causing setuid bit removal is failed.
458 * Security hooks for file operations
461 * Check file permissions before accessing an open file. This hook is
462 * called by various operations that read or write files. A security
463 * module can use this hook to perform additional checking on these
464 * operations, e.g. to revalidate permissions on use to support privilege
465 * bracketing or policy changes. Notice that this hook is used when the
466 * actual read/write operations are performed, whereas the
467 * inode_security_ops hook is called when a file is opened (as well as
468 * many other operations).
469 * Caveat: Although this hook can be used to revalidate permissions for
470 * various system call operations that read or write files, it does not
471 * address the revalidation of permissions for memory-mapped files.
472 * Security modules must handle this separately if they need such
474 * @file contains the file structure being accessed.
475 * @mask contains the requested permissions.
476 * Return 0 if permission is granted.

491 * sometimes represents a user space pointer; in other cases, it may be a
492 * simple integer value. When @arg represents a user space pointer, it
493 * should never be used by the security module.
494 * Return 0 if permission is granted.
496 * Check permissions for a mmap operation. The @file may be NULL, e.g.
497 * if mapping anonymous memory.
498 * @file contains the file structure for file to map (may be NULL).
499 * @reqprot contains the protection requested by the application.

517 * Check permission before allowing the file operation specified by @cmd
518 * from being performed on the file @file. Note that @arg can sometimes
519 * represents a user space pointer; in other cases, it may be a simple
520 * integer value. When @arg represents a user space pointer, it should
521 * never be used by the security module.
522 * @file contains the file structure.
523 * @cmd contains the operation to be performed.
524 * @arg contains the operational arguments.
525 * Return 0 if permission is granted.

530 * Return 0 on success.
531 * @file_send_sigiotask:

1081 * Allocate and attach a security structure to the sma->sem_perm.security
1082 * field. The security field is initialized to NULL when the structure is
1084 * @sma contains the semaphore structure
1085 * Return 0 if operation was successful and permission is granted.
1086 * @sem_free_security:
1087 * deallocate security struct for this semaphore
1088 * @sma contains the semaphore structure.
1090 * Check permission when a semaphore is requested through the semget
1091 * system call. This hook is only called when returning the semaphore
1092 * identifier for an existing semaphore, not when a new one must be
1094 * @sma contains the semaphore structure.
1095 * @semflg contains the operation control flags.
1096 * Return 0 if permission is granted.
1098 * Check permission when a semaphore operation specified by @cmd is to be
1099 * performed on the semaphore @sma. The @sma may be NULL, e.g. for
1100 * IPC_INFO or SEM_INFO.
1101 * @sma contains the semaphore structure. May be NULL.
1102 * @cmd contains the operation to be performed.
1103 * Return 0 if permission is granted.
1105 * Check permissions before performing operations on members of the
1106 * semaphore set @sma. If the @alter flag is nonzero, the semaphore set
1108 * @sma contains the semaphore structure.
1109 * @sops contains the operations to perform.
1110 * @nsops contains the number of operations to perform.
1111 * @alter contains the flag indicating whether changes are to be made.
1112 * Return 0 if permission is granted.
1115 * Check permission before allowing the @parent process to trace the
1117 * Security modules may also want to perform a process tracing check
1118 * during an execve in the set_security or apply_creds hooks of
1119 * binprm_security_ops if the process is being traced and its security
1120 * attributes would be changed by the execve.
1121 * @parent contains the task_struct structure for parent process.
1122 * @child contains the task_struct structure for child process.
1123 * Return 0 if permission is granted.
1125 * Get the @effective, @inheritable, and @permitted capability sets for
1126 * the @target process. The hook may also perform permission checking to
1127 * determine if the current process is allowed to see the capability sets
1128 * of the @target process.
1129 * @target contains the task_struct structure for target process.
1130 * @effective contains the effective capability set.
1131 * @inheritable contains the inheritable capability set.
1132 * @permitted contains the permitted capability set.
1133 * Return 0 if the capability sets were successfully obtained.
1135 * Check permission before setting the @effective, @inheritable, and
1136 * @permitted capability sets for the @target process.
1137 * Caveat: @target is also set to current if a set of processes is
1138 * specified (i.e. all processes other than current and init or a
1139 * particular process group). Hence, the capset_set hook may need to
1140 * revalidate permission to the actual target process.
1141 * @target contains the task_struct structure for target process.
1142 * @effective contains the effective capability set.
1143 * @inheritable contains the inheritable capability set.
1144 * @permitted contains the permitted capability set.
1145 * Return 0 if permission is granted.
1147 * Set the @effective, @inheritable, and @permitted capability sets for
1148 * the @target process. Since capset_check cannot always check permission
1149 * to the real @target process, this hook may also perform permission
1150 * checking to determine if the current process is allowed to set the
1151 * capability sets of the @target process. However, this hook has no way
1152 * of returning an error due to the structure of the sys_capset code.
1153 * @target contains the task_struct structure for target process.
1154 * @effective contains the effective capability set.
1155 * @inheritable contains the inheritable capability set.
1156 * @permitted contains the permitted capability set.
1158 * Check whether the @tsk process has the @cap capability.
1159 * @tsk contains the task_struct for the process.
1160 * @cap contains the capability <include/linux/capability.h>.
1161 * Return 0 if the capability is granted for @tsk.
1163 * Check permission before enabling or disabling process accounting. If
1164 * accounting is being enabled, then @file refers to the open file used to
1165 * store accounting records. If accounting is being disabled, then @file
1167 * @file contains the file structure for the accounting file (may be NULL).
1168 * Return 0 if permission is granted.
1170 * Check permission before accessing the @table sysctl variable in the
1171 * manner specified by @op.
1172 * @table contains the ctl_table structure for the sysctl variable.
1173 * @op contains the operation (001 = search, 002 = write, 004 = read).
1174 * Return 0 if permission is granted.
1176 * Check permission before accessing the kernel message ring or changing
1177 * logging to the console.
1178 * See the syslog(2) manual page for an explanation of the @type values.
1179 * @type contains the type of action.
1180 * Return 0 if permission is granted.
1182 * Check permission to change the system time.
1183 * struct timespec and timezone are defined in include/linux/time.h
1184 * @ts contains new time
1185 * @tz contains new timezone
1186 * Return 0 if permission is granted.
1187 * @vm_enough_memory:
1188 * Check permissions for allocating a new virtual mapping.
1189 * @mm contains the mm struct it is being added to.
1190 * @pages contains the number of pages.
1191 * Return 0 if permission is granted.
1193 * @register_security:
1194 * allow module stacking.
1195 * @name contains the name of the security module being stacked.
1196 * @ops contains a pointer to the struct security_operations of the module to stack.
1199 * Convert secid to security context.
1200 * @secid contains the security ID.
1201 * @secdata contains the pointer that stores the converted security context.
1203 * Convert security context to secid.
1204 * @secid contains the pointer to the generated security ID.
1205 * @secdata contains the security context.
1208 * Release the security context.
1209 * @secdata contains the security context.
1210 * @seclen contains the length of the security context.
1212 * This is the main security structure.
