Lines Matching full:symlink

171  * fscrypt_prepare_symlink() - prepare to create a possibly-encrypted symlink
172  * @dir: directory in which the symlink is being created
173  * @target: plaintext symlink target
175  * @max_len: space the filesystem has available to store the symlink target
176  * @disk_link: (out) the on-disk symlink target being prepared
178  * This function computes the size the symlink target will require on-disk,
180  * encrypted symlink may be longer than the original.
182  * Additionally, @disk_link->name is set to @target if the symlink will be
183  * unencrypted, but left NULL if the symlink will be encrypted.  For encrypted
186  * filesystems need to know the size of the symlink target before creating the
187  * inode, e.g. to determine whether it will be a "fast" or "slow" symlink.)
189  * Return: 0 on success, -ENAMETOOLONG if the symlink target is too long,
200 	 * To calculate the size of the encrypted symlink target we need to know  in fscrypt_prepare_symlink()
217 	 * Calculate the size of the encrypted symlink and verify it won't  in fscrypt_prepare_symlink()
218 	 * exceed max_len.  Note that for historical reasons, encrypted symlink  in fscrypt_prepare_symlink()
221 	 * longest symlink target we can accept.  in fscrypt_prepare_symlink()
248 	 * symlink inode's encryption key.  We don't wait until now to do it,  in __fscrypt_encrypt_symlink()
277 	/* Cache the plaintext symlink target for later use by get_link() */  in __fscrypt_encrypt_symlink()
295  * fscrypt_get_symlink() - get the target of an encrypted symlink
296  * @inode: the symlink inode
297  * @caddr: the on-disk contents of the symlink
301  * If the symlink's encryption key is available, we decrypt its target.
306  * Return: the presentable symlink target or an ERR_PTR()
327 	 * Try to set up the symlink's encryption key, but we can continue  in fscrypt_get_symlink()
336 	 * For historical reasons, encrypted symlink targets are prefixed with  in fscrypt_get_symlink()
367 	 * Cache decrypted symlink targets in i_link for later use.  Don't cache  in fscrypt_get_symlink()
368 	 * symlink targets encoded without the key, since those become outdated  in fscrypt_get_symlink()
386  * @path: the path for the encrypted symlink being queried
387  * @stat: the struct being filled with the symlink's attributes
390  * symlink target (or the no-key encoded symlink target, if the key is
