-If this patch does not apply cleanly to newer version of util-linux-ng, try
-replacing original lomount.c lomount.h loop.h losetup.8 files in mount
-subdirectory with versions from util-linux-ng that the patch is for. And
-then apply this patch.
-
-mount/Makefile.in is a generated file. You can ignore patch failures on that
-file if you generate it again by running the ./autogen.sh script. That
-./autogen.sh script needs recent versions of autohell tools.

--.SS "Encryption"
--It is possible to specify transfer functions (for encryption/decryption
--or other purposes) using one of the
--.B \-E
--and
--.B \-e
--options.
--There are two mechanisms to specify the desired encryption: by number
--and by name. If an encryption is specified by number then one
--has to make sure that the Linux kernel knows about the encryption with that
--number, probably by patching the kernel. Standard numbers that are
--always present are 0 (no encryption) and 1 (XOR encryption).
--When the cryptoloop module is loaded (or compiled in), it uses number 18.
--This cryptoloop module will take the name of an arbitrary encryption type
--and finds the module that knows how to perform that encryption.
- .SH OPTIONS
--.IP "\fB\-a, \-\-all\fP"
--show status of all loop devices
--.IP "\fB\-d, \-\-detach\fP"
--detach the file or device associated with the specified loop device
--.IP "\fB\-e, \-E, \-\-encryption \fIencryption_type\fP"
--enable data encryption with specified name or number
--.IP "\fB\-f, \-\-find\fP"

-+.IP \fB\-a\fP
-+Show status of all loop devices.
-+.IP "\fB\-C \fIitercountk\fP"
-+Runs hashed passphrase through \fIitercountk\fP thousand iterations of AES-256
-+before using it for loop encryption. This consumes lots of CPU cycles at
-+loop setup/mount time but not thereafter. In combination with passphrase seed
-+this slows down dictionary attacks. Iteration is not done in multi-key mode.
-+.IP "\fB\-d\fP"
-+Detach the file or device associated with the specified loop device.
-+.IP "\fB\-e \fIencryption\fP"
-+.RS
-+Enable data encryption. Following encryption types are recognized:
-+.IP \fBNONE\fP
-+Use no encryption (default).
-+.PD 0
-+.IP \fBXOR\fP
-+Use a simple XOR encryption.
-+.IP "\fBAES128 AES\fP"
-+Use 128 bit AES encryption. Passphrase is hashed with SHA-256 by default.
-+.IP \fBAES192\fP
-+Use 192 bit AES encryption. Passphrase is hashed with SHA-384 by default.
-+.IP \fBAES256\fP
-+Use 256 bit AES encryption. Passphrase is hashed with SHA-512 by default.
-+
-+.IP "\fBtwofish128 twofish160 twofish192 twofish256\fP"

-+configuration or corresponding modules have been loaded to kernel.

-+Reads and uses mount options from /etc/fstab that match specified loop
-+device, including offset= sizelimit= encryption= pseed= phash= loinit=
-+gpgkey= gpghome= cleartextkey= itercountk= and looped to device/file name.
-+loop= option in /etc/fstab must match specified loop device name. Command
-+line options take precedence in case of conflict.
-+.IP "\fB\-G \fIgpghome\fP"
-+Set gpg home directory to \fIgpghome\fP, so that gpg uses public/private
-+keys on \fIgpghome\fP directory. This is only used when gpgkey file needs to
-+be decrypted using public/private keys. If gpgkey file is encrypted with
-+symmetric cipher only, public/private keys are not required and this option
-+has no effect.
-+.IP "\fB\-H \fIphash\fP"
-+Uses \fIphash\fP function to hash passphrase. Available hash functions are
-+sha256, sha384, sha512 and rmd160. unhashed1, unhashed2 and unhashed3
-+functions also exist for compatibility with some obsolete implementations.
-+
-+Hash function random does not ask for passphrase but sets up random keys and
-+attempts to put loop to multi-key mode. When random/1777 hash type is used
-+as mount option for mount program, mount program will create new file system
-+on the loop device and construct initial permissions of file system root
-+directory from octal digits that follow the slash character.
-+
-+WARNING! DO NOT USE RANDOM HASH TYPE ON PARTITION WITH EXISTING IMPORTANT
-+DATA ON IT. RANDOM HASH TYPE WILL DESTROY YOUR DATA.
-+.IP "\fB\-I \fIloinit\fP"
-+Passes a numeric value of \fIloinit\fP as a parameter to cipher transfer
-+function. Cipher transfer functions are free to interpret value as they
-+want.
-+.IP "\fB\-K \fIgpgkey\fP"
-+Passphrase is piped to gpg so that gpg can decrypt file \fIgpgkey\fP which
-+contains the real keys that are used to encrypt loop device. If decryption
-+requires public/private keys and gpghome is not specified, all users use
-+their own gpg public/private keys to decrypt \fIgpgkey\fP. Decrypted
-+\fIgpgkey\fP should contain 1 or 64 or 65 keys, each key at least 20
-+characters and separated by newline. If decrypted \fIgpgkey\fP contains 64
-+or 65 keys, then loop device is put to multi-key mode. In multi-key mode
-+first key is used for first sector, second key for second sector, and so on.
-+65th key, if present, is used as additional input to MD5 IV computation.

-+Read the passphrase from file descriptor \fIpasswdfd\fP instead of the

-+attempts to read 65 keys from \fIpasswdfd\fP, each key at least 20
-+characters and separated by newline. If losetup successfully reads 64 or 65
-+keys, then loop device is put to multi-key mode. If losetup encounters
-+end-of-file before 64 keys are read, then only first key is used in
-+single-key mode.
-+
-+echo SecretPassphraseHere | losetup -p0 -K foo.gpg -e AES128 ...
- 
-+In above example, losetup reads passphrase from file descriptor 0 (stdin).
-+.IP "\fB\-P \fIcleartextkey\fP"
-+Read the passphrase from file \fIcleartextkey\fP instead of the
-+terminal. If -K option is not being used (no gpg key file), then losetup
-+attempts to read 65 keys from \fIcleartextkey\fP, each key at least 20
-+characters and separated by newline. If losetup successfully reads 64 or 65
-+keys, then loop device is put to multi-key mode. If losetup encounters
-+end-of-file before 64 keys are read, then only first key is used in
-+single-key mode. If both -p and -P options are used, then -p option takes
-+precedence. These are equivalent:

-+losetup -p3 -K foo.gpg -e AES128 ...   3<someFileName

-+losetup -P someFileName -K foo.gpg -e AES128 ...
-+
-+In first line of above example, in addition to normal open file descriptors
-+(0==stdin 1==stdout 2==stderr), shell opens the file and passes open file
-+descriptor to started losetup program. In second line of above example,
-+losetup opens the file itself.
-+.IP "\fB\-r\fP"
-+Read-only mode.
-+.IP "\fB\-R\fP"
-+Resize existing, already set up loop device, to new changed underlying

-+LVM volume. This functionality may not be supported on some older kernels
-+and/or loop drivers.
-+.IP "\fB\-s \fIsizelimit\fP"
-+Size of loop device is limited to \fIsizelimit\fP bytes. If unspecified or
-+set to zero, loop device size is set to maximum available (file size minus
-+offset). This option may not be supported on some older kernels and/or loop
-+drivers.
-+.IP "\fB\-S \fIpseed\fP"
-+Sets encryption passphrase seed \fIpseed\fP which is appended to user supplied
-+passphrase before hashing. Using different seeds for different partitions
-+makes dictionary attacks slower but does not prevent them if user supplied
