Hi, I'm trying to use cryptsetup on beaglebone to encrypt some data. cryptsetup version is 1.6.2. When running luksFormat (with verbose option) I get following: # Allocating crypt device /dev/loop0 context. # Trying to open and read device /dev/loop0. # Initialising device-mapper backend library. # Timeout set to 0 miliseconds. # Iteration time set to 1000 miliseconds. # Interactive passphrase entry requested. Enter passphrase: Verify passphrase: # Formatting device /dev/loop0 as type LUKS1. # Crypto backend (gcrypt 1.5.0) initialized. # Topology: IO (512/0), offset = 0; Required alignment is 1048576 bytes. # Generating LUKS header version 1 using hash sha1, aes, cbc-essiv:sha256, MK 32 bytes # Crypto backend (gcrypt 1.5.0) initialized. # KDF pbkdf2, hash sha1: 18204 iterations per second. # Data offset 4096, UUID 9b15dba5-058d-4b81-aa14-e085698e87c1, digest iterations 2125 # Updating LUKS header of size 1024 on device /dev/loop0 # Key length 32, device size 8192 sectors, header size 2050 sectors. # Reading LUKS header of size 1024 from device /dev/loop0 # Key length 32, device size 8192 sectors, header size 2050 sectors. # Adding new keyslot -1 using volume key. # Calculating data for key slot 0 # Crypto backend (gcrypt 1.5.0) initialized. # KDF pbkdf2, hash sha1: 18204 iterations per second. # Key slot 0 use 8888 password iterations. # Using hash sha1 for AF in key slot 0, 4000 stripes # Updating key slot 0 [0x1000] area. # Calculated device size is 250 sectors (RW), offset 8. # Detected kernel Linux 3.9.0-g7897c55-dirty armv7l. Couldn't create ioctl argument. Cannot initialize device-mapper. Is dm_mod kernel module loaded? # Releasing crypt device /dev/loop0 context. # Releasing device-mapper backend. # Unlocking memory. Command failed with code 5: Cannot initialize device-mapper. Is dm_mod kernel module loaded? I track it down that malloc fails (ENONMEM) in libdevmapper and then _dm_check_versions() fails when creating dm task (dmt = dm_task_create(DM_DEVICE_LIST_VERSIONS). There is enough of free memory in this case: total used free shared buffers Mem: 247396 68656 178740 0 0 Any idea why allocation runs out of memory and due to that cryptsetup fails? Thanks in advance.
