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

251 * Allocate and attach a security structure to @inode->i_security. The
252 * i_security field is initialized to NULL when the inode structure is
254 * @inode contains the inode structure.
255 * Return 0 if operation was successful.
256 * @inode_free_security:
257 * @inode contains the inode structure.
258 * Deallocate the inode security structure and set @inode->i_security to
260 * @inode_init_security:
261 * Obtain the security attribute name suffix and value to set on a newly
262 * created inode and set up the incore security field for the new inode.
263 * This hook is called by the fs code as part of the inode creation
264 * transaction and provides for atomic labeling of the inode, unlike
265 * the post_create/mkdir/... hooks called by the VFS. The hook function
266 * is expected to allocate the name and value via kmalloc, with the caller
267 * being responsible for calling kfree after using them.
268 * If the security module does not use security attributes or does
269 * not wish to put a security attribute on this particular inode,
270 * then it should return -EOPNOTSUPP to skip this processing.
271 * @inode contains the inode structure of the newly created inode.
272 * @dir contains the inode structure of the parent directory.
273 * @name will be set to the allocated name suffix (e.g. selinux).
274 * @value will be set to the allocated attribute value.
275 * @len will be set to the length of the value.
276 * Returns 0 if @name and @value have been successfully set,
277 * -EOPNOTSUPP if no security attribute is needed, or
278 * -ENOMEM on memory allocation failure.
280 * Check permission to create a regular file.
281 * @dir contains inode structure of the parent of the new file.
282 * @dentry contains the dentry structure for the file to be created.
283 * @mode contains the file mode of the file to be created.
284 * Return 0 if permission is granted.
286 * Check permission before creating a new hard link to a file.
287 * @old_dentry contains the dentry structure for an existing link to the file.
288 * @dir contains the inode structure of the parent directory of the new link.
289 * @new_dentry contains the dentry structure for the new link.
290 * Return 0 if permission is granted.
292 * Check the permission to remove a hard link to a file.
293 * @dir contains the inode structure of parent directory of the file.

313 * Return 0 if permission is granted.
315 * Check permissions when creating a special file (or a socket or a fifo
316 * file created via the mknod system call). Note that if mknod operation
317 * is being done for a regular file, then the create hook will be called

320 * @dentry contains the dentry structure of the new file.
321 * @mode contains the mode of the new file.
322 * @dev contains the the device number.

332 * Check the permission to read the symbolic link.
333 * @dentry contains the dentry structure for the file link.
334 * Return 0 if permission is granted.
335 * @inode_follow_link:
336 * Check permission to follow a symbolic link when looking up a pathname.
337 * @dentry contains the dentry structure for the link.
338 * @nd contains the nameidata structure for the parent directory.
339 * Return 0 if permission is granted.
341 * Check permission before accessing an inode. This hook is called by the
342 * existing Linux permission function, so a security module can use it to
343 * provide additional checking for existing Linux permission checks.
344 * Notice that this hook is called when a file is opened (as well as many
345 * other operations), whereas the file_security_ops permission hook is
346 * called when the actual read/write operations are performed.
347 * @inode contains the inode structure to check.
348 * @mask contains the permission mask.
349 * @nd contains the nameidata (may be NULL).
350 * Return 0 if permission is granted.
352 * Check permission before setting file attributes. Note that the kernel
353 * call to notify_change is performed from several locations, whenever
354 * file attributes change (such as when a file is truncated, chown/chmod
355 * operations, transferring disk quotas, etc).
356 * @dentry contains the dentry structure for the file.
357 * @attr is the iattr structure containing the new file attributes.
358 * Return 0 if permission is granted.

362 * @dentry contains the dentry structure for the file.
363 * Return 0 if permission is granted.
365 * @inode contains the inode structure for deleted inode.
366 * This hook is called when a deleted inode is released (i.e. an inode
367 * with no hard links has its use count drop to zero). A security module

388 * Return 0 if permission is granted.
389 * @inode_getsecurity:
390 * Copy the extended attribute representation of the security label
391 * associated with @name for @inode into @buffer. @buffer may be
392 * NULL to request the size of the buffer required. @size indicates
393 * the size of @buffer in bytes. Note that @name is the remainder
394 * of the attribute name after the security. prefix has been removed.
395 * @err is the return value from the preceding fs getxattr call,
396 * and can be used by the security module to determine whether it

399 * @inode_setsecurity:
400 * Set the security label associated with @name for @inode from the
401 * extended attribute value @value. @size indicates the size of the
402 * @value in bytes. @flags may be XATTR_CREATE, XATTR_REPLACE, or 0.

404 * security. prefix has been removed.
405 * Return 0 on success.
406 * @inode_listsecurity:
407 * Copy the extended attribute names for the security labels
408 * associated with @inode into @buffer. The maximum size of @buffer
409 * is specified by @buffer_size. @buffer may be NULL to request
410 * the size of the buffer required.
411 * Returns number of bytes used/required on success.
413 * Security hooks for file operations
416 * Check file permissions before accessing an open file. This hook is
417 * called by various operations that read or write files. A security
418 * module can use this hook to perform additional checking on these
419 * operations, e.g. to revalidate permissions on use to support privilege
420 * bracketing or policy changes. Notice that this hook is used when the
421 * actual read/write operations are performed, whereas the
422 * inode_security_ops hook is called when a file is opened (as well as
423 * many other operations).
424 * Caveat: Although this hook can be used to revalidate permissions for
425 * various system call operations that read or write files, it does not
426 * address the revalidation of permissions for memory-mapped files.
427 * Security modules must handle this separately if they need such
429 * @file contains the file structure being accessed.
430 * @mask contains the requested permissions.
431 * Return 0 if permission is granted.
432 * @file_alloc_security:
433 * Allocate and attach a security structure to the file->f_security field.
434 * The security field is initialized to NULL when the structure is first
436 * @file contains the file structure to secure.

446 * sometimes represents a user space pointer; in other cases, it may be a
447 * simple integer value. When @arg represents a user space pointer, it
448 * should never be used by the security module.
449 * Return 0 if permission is granted.
451 * Check permissions for a mmap operation. The @file may be NULL, e.g.
452 * if mapping anonymous memory.
453 * @file contains the file structure for file to map (may be NULL).
454 * @reqprot contains the protection requested by the application.
455 * @prot contains the protection that will be applied by the kernel.
456 * @flags contains the operational flags.
457 * Return 0 if permission is granted.
459 * Check permissions before changing memory access permissions.
460 * @vma contains the memory region to modify.
461 * @reqprot contains the protection requested by the application.
462 * @prot contains the protection that will be applied by the kernel.
463 * Return 0 if permission is granted.

472 * Check permission before allowing the file operation specified by @cmd
473 * from being performed on the file @file. Note that @arg can sometimes
474 * represents a user space pointer; in other cases, it may be a simple
475 * integer value. When @arg represents a user space pointer, it should
476 * never be used by the security module.
477 * @file contains the file structure.
478 * @cmd contains the operation to be performed.
479 * @arg contains the operational arguments.
480 * Return 0 if permission is granted.
482 * Save owner security information (typically from current->security) in
483 * file->f_security for later use by the send_sigiotask hook.
484 * @file contains the file structure to update.
485 * Return 0 on success.
486 * @file_send_sigiotask:
487 * Check permission for the file owner @fown to send SIGIO or SIGURG to the
488 * process @tsk. Note that this hook is sometimes called from interrupt.
489 * Note that the fown_struct, @fown, is never outside the context of a
490 * struct file, so the file structure (and associated security information)
491 * can always be obtained:
492 * (struct file *)((long)fown - offsetof(struct file,f_owner));
493 * @tsk contains the structure of task receiving signal.
494 * @fown contains the file owner information.
495 * @sig is the signal that will be sent. When 0, kernel sends SIGIO.

507 * manual page for definitions of the @clone_flags.
508 * @clone_flags contains the flags indicating what should be shared.
509 * Return 0 if permission is granted.
510 * @task_alloc_security:
511 * @p contains the task_struct for child process.
512 * Allocate and attach a security structure to the p->security field. The
513 * security field is initialized to NULL when the task structure is

517 * @p contains the task_struct for process.
518 * Deallocate and clear the p->security field.
520 * Check permission before setting one or more of the user identity
521 * attributes of the current process. The @flags parameter indicates
522 * which of the set*uid system calls invoked this hook and how to
523 * interpret the @id0, @id1, and @id2 parameters. See the LSM_SETID
524 * definitions at the beginning of this file for the @flags values and
526 * @id0 contains a uid.
527 * @id1 contains a uid.
528 * @id2 contains a uid.
529 * @flags contains one of the LSM_SETID_* values.
530 * Return 0 if permission is granted.
532 * Update the module's state after setting one or more of the user
533 * identity attributes of the current process. The @flags parameter
