| 198 | * Save security information in the bprm->security field, typically based
|
| 199 | * on information about the bprm->file, for later use by the apply_creds
|
| 200 | * hook. This hook may also optionally check permissions (e.g. for
|
| 201 | * transitions between security domains).
|
| 202 | * This hook may be called multiple times during a single execve, e.g. for
|
| 203 | * interpreters. The hook can tell whether it has already been called by
|
| 204 | * checking to see if @bprm->security is non-NULL. If so, then the hook
|
| 205 | * may decide either to retain the security information saved earlier or
|
| 206 | * to replace it.
|
| 207 | * @bprm contains the linux_binprm structure.
|
| 208 | * Return 0 if the hook is successful and permission is granted.
|
| 209 | * @bprm_check_security:
|
| 210 | * This hook mediates the point when a search for a binary handler will
|
| 211 | * begin. It allows a check the @bprm->security value which is set in the
|
| 212 | * preceding set_creds call. The primary difference from set_creds is
|
| 213 | * that the argv list and envp list are reliably available in @bprm. This
|
| 214 | * hook may be called multiple times during a single execve; and in each
|
| 215 | * pass set_creds is called first.
|
| 216 | * @bprm contains the linux_binprm structure.
|
| 217 | * Return 0 if the hook is successful and permission is granted.
|
| 218 | * @bprm_committing_creds:
|
| 219 | * Prepare to install the new security attributes of a process being
|
| 220 | * transformed by an execve operation, based on the old credentials
|
| 221 | * pointed to by @current->cred and the information set in @bprm->cred by
|
| 222 | * the bprm_set_creds hook. @bprm points to the linux_binprm structure.
|
| 223 | * This hook is a good place to perform state changes on the process such
|
| 224 | * as closing open file descriptors to which access will no longer be
|
| 225 | * granted when the attributes are changed. This is called immediately
|
| 226 | * before commit_creds().
|
| 227 | * @bprm_committed_creds:
|
| 228 | * Tidy up after the installation of the new security attributes of a
|
| 229 | * process being transformed by an execve operation. The new credentials
|
| 230 | * have, by this point, been set to @current->cred. @bprm points to the
|
| 231 | * linux_binprm structure. This hook is a good place to perform state
|
| 232 | * changes on the process such as clearing out non-inheritable signal
|
| 233 | * state. This is called immediately after commit_creds().
|
| 234 | * @bprm_secureexec:
|
| 235 | * Return a boolean value (0 or 1) indicating whether a "secure exec"
|
| 236 | * is required. The flag is passed in the auxiliary table
|
| 237 | * on the initial stack to the ELF interpreter to indicate whether libc
|
| 238 | * should enable secure mode.
|
| 239 | * @bprm contains the linux_binprm structure.
|
| 240 | *
|
| 241 | * Security hooks for filesystem operations.
|
| 242 | *
|
| 243 | * @sb_alloc_security:
|
| 244 | * Allocate and attach a security structure to the sb->s_security field.
|
| 245 | * The s_security field is initialized to NULL when the structure is
|
| 246 | * allocated.
|
| 247 | * @sb contains the super_block structure to be modified.
|
| 248 | * Return 0 if operation was successful.
|
| 249 | * @sb_free_security:
|
| 250 | * Deallocate and clear the sb->s_security field.
|
| 251 | * @sb contains the super_block structure to be modified.
|
| 252 | * @sb_statfs:
|
| 253 | * Check permission before obtaining filesystem statistics for the @mnt
|
| 254 | * mountpoint.
|
| 255 | * @dentry is a handle on the superblock for the filesystem.
|
| 256 | * Return 0 if permission is granted.
|
| 257 | * @sb_mount:
|
| 258 | * Check permission before an object specified by @dev_name is mounted on
|
| 259 | * the mount point named by @nd. For an ordinary mount, @dev_name
|
| 260 | * identifies a device if the file system type requires a device. For a
|
| 261 | * remount (@flags & MS_REMOUNT), @dev_name is irrelevant. For a
|
| 262 | * loopback/bind mount (@flags & MS_BIND), @dev_name identifies the
|
| 263 | * pathname of the object being mounted.
|
| 264 | * @dev_name contains the name for object being mounted.
|
| 265 | * @path contains the path for mount point object.
|
| 266 | * @type contains the filesystem type.
|
| 267 | * @flags contains the mount flags.
|
| 268 | * @data contains the filesystem-specific data.
|
| 269 | * Return 0 if permission is granted.
|
| 270 | * @sb_copy_data:
|
| 271 | * Allow mount option data to be copied prior to parsing by the filesystem,
|
| 272 | * so that the security module can extract security-specific mount
|
| 273 | * options cleanly (a filesystem may modify the data e.g. with strsep()).
|
| 274 | * This also allows the original mount data to be stripped of security-
|
| 275 | * specific options to avoid having to make filesystems aware of them.
|
| 276 | * @type the type of filesystem being mounted.
|
| 277 | * @orig the original mount data copied from userspace.
|
| 278 | * @copy copied data which will be passed to the security module.
|
| 279 | * Returns 0 if the copy was successful.
|
| 280 | * @sb_remount:
|
| 281 | * Extracts security system specific mount options and verifies no changes
|
| 282 | * are being made to those options.
|
| 283 | * @sb superblock being remounted
|
| 284 | * @data contains the filesystem-specific data.
|
| 285 | * Return 0 if permission is granted.
|
| 286 | * @sb_umount:
|
| 287 | * Check permission before the @mnt file system is unmounted.
|
| 288 | * @mnt contains the mounted file system.
|
| 289 | * @flags contains the unmount flags, e.g. MNT_FORCE.
|
| 290 | * Return 0 if permission is granted.
|
| 291 | * @sb_pivotroot:
|
| 292 | * Check permission before pivoting the root filesystem.
|
| 293 | * @old_path contains the path for the new location of the current root (put_old).
|
| 294 | * @new_path contains the path for the new root (new_root).
|
| 295 | * Return 0 if permission is granted.
|
| 296 | * @sb_set_mnt_opts:
|
| 297 | * Set the security relevant mount options used for a superblock
|
| 298 | * @sb the superblock to set security mount options for
|
| 299 | * @opts binary data structure containing all lsm mount data
|
| 300 | * @sb_clone_mnt_opts:
|
| 301 | * Copy all security options from a given superblock to another
|
| 302 | * @oldsb old superblock which contain information to clone
|
| 303 | * @newsb new superblock which needs filled in
|
| 304 | * @sb_parse_opts_str:
|
| 305 | * Parse a string of security data filling in the opts structure
|
| 306 | * @options string containing all mount options known by the LSM
|
| 307 | * @opts binary data structure usable by the LSM
|
| 308 | *
|
| 309 | * Security hooks for inode operations.
|
| 310 | *
|
| 311 | * @inode_alloc_security:
|
| 312 | * Allocate and attach a security structure to @inode->i_security. The
|
| 313 | * i_security field is initialized to NULL when the inode structure is
|
| 314 | * allocated.
|
| 315 | * @inode contains the inode structure.
|
| 316 | * Return 0 if operation was successful.
|
| 317 | * @inode_free_security:
|
| 318 | * @inode contains the inode structure.
|
| 319 | * Deallocate the inode security structure and set @inode->i_security to
|
| 320 | * NULL.
|
| 321 | * @inode_init_security:
|
| 322 | * Obtain the security attribute name suffix and value to set on a newly
|
| 323 | * created inode and set up the incore security field for the new inode.
|
| 324 | * This hook is called by the fs code as part of the inode creation
|
| 325 | * transaction and provides for atomic labeling of the inode, unlike
|
| 326 | * the post_create/mkdir/... hooks called by the VFS. The hook function
|
| 327 | * is expected to allocate the name and value via kmalloc, with the caller
|
| 328 | * being responsible for calling kfree after using them.
|
| 329 | * If the security module does not use security attributes or does
|
| 330 | * not wish to put a security attribute on this particular inode,
|
| 331 | * then it should return -EOPNOTSUPP to skip this processing.
|
| 332 | * @inode contains the inode structure of the newly created inode.
|
| 333 | * @dir contains the inode structure of the parent directory.
|
| 334 | * @qstr contains the last path component of the new object
|
| 335 | * @name will be set to the allocated name suffix (e.g. selinux).
|
| 336 | * @value will be set to the allocated attribute value.
|
| 337 | * @len will be set to the length of the value.
|
| 338 | * Returns 0 if @name and @value have been successfully set,
|
| 339 | * -EOPNOTSUPP if no security attribute is needed, or
|
| 340 | * -ENOMEM on memory allocation failure.
|
| 341 | * @inode_create:
|
| 342 | * Check permission to create a regular file.
|
| 343 | * @dir contains inode structure of the parent of the new file.
|
| 344 | * @dentry contains the dentry structure for the file to be created.
|
| 345 | * @mode contains the file mode of the file to be created.
|
| 346 | * Return 0 if permission is granted.
|
| 347 | * @inode_link:
|
| 348 | * Check permission before creating a new hard link to a file.
|
| 349 | * @old_dentry contains the dentry structure for an existing link to the file.
|
| 350 | * @dir contains the inode structure of the parent directory of the new link.

|
| 587 | * should never be used by the security module.

| 588 | * Return 0 if permission is granted.
|
| 589 | * @file_mmap :
|
| 590 | * Check permissions for a mmap operation. The @file may be NULL, e.g.

|
| 801 | * grained control over message transmission.
|
| 802 | * @sk associated sock of task sending the message.
|
| 803 | * @skb contains the sk_buff structure for the netlink message.

|
| 824 | * Linux provides an alternative to the conventional file name space for Unix
|
| 825 | * domain sockets. Whereas binding and connecting to sockets in the file name
|
| 826 | * space is mediated by the typical file permissions (and caught by the mknod
|
| 827 | * and permission hooks in inode_security_ops), binding and connecting to
|
| 828 | * sockets in the abstract name space is completely unmediated. Sufficient
|
| 829 | * control of Unix domain sockets in the abstract name space isn't possible
|
| 830 | * using only the socket layer hooks, since we need to know the actual target
|
| 831 | * socket, which is not looked up until we are inside the af_unix code.
