appropriate kernel configuration parameters need to be set:

First, apply a patch to fix a build problem caused by API changes in
|
|
<xref role="nodep" linkend="json-c"/>:

|
</para>
|
|
|
|
<screen><userinput remap="pre">patch -Np1 -i ../cryptsetup-&cryptsetup-version;-upstream_fixes-1.patch</userinput></screen>

Install <application>cryptsetup</application> by running the following

commands:

|
|
|
|
<screen><userinput>./configure --prefix=/usr &&
|

make</userinput></screen>
|

<para>

|
To test the result, issue as the <systemitem

|
|
Some tests will fail if appropriate kernel configuration options are not
|
|
set. Some additional options that may be needed for tests are:
|
|
CONFIG_SCSI_LOWLEVEL,
|
|
CONFIG_SCSI_DEBUG,
|
|
CONFIG_BLK_DEV_DM_BUILTIN,
|
|
CONFIG_CRYPTO_USER,

CONFIG_CRYPTO_XTS,

CONFIG_CRYPTO_CRCT10DIF,

CONFIG_CRYPTO_AES_TI,

CONFIG_CRYPTO_AES_NI_INTEL,

CONFIG_CRYPTO_BLOWFISH,
