RHEL Engineering is moving the tracking of its product development work on RHEL 6 through RHEL 9 to Red Hat Jira (issues.redhat.com). If you're a Red Hat customer, please continue to file support cases via the Red Hat customer portal. If you're not, please head to the "RHEL project" in Red Hat Jira and file new tickets here. Individual Bugzilla bugs in the statuses "NEW", "ASSIGNED", and "POST" are being migrated throughout September 2023. Bugs of Red Hat partners with an assigned Engineering Partner Manager (EPM) are migrated in late September as per pre-agreed dates. Bugs against components "kernel", "kernel-rt", and "kpatch" are only migrated if still in "NEW" or "ASSIGNED". If you cannot log in to RH Jira, please consult article #7032570. That failing, please send an e-mail to the RH Jira admins at rh-issues@redhat.com to troubleshoot your issue as a user management inquiry. The email creates a ServiceNow ticket with Red Hat. Individual Bugzilla bugs that are migrated will be moved to status "CLOSED", resolution "MIGRATED", and set with "MigratedToJIRA" in "Keywords". The link to the successor Jira issue will be found under "Links", have a little "two-footprint" icon next to it, and direct you to the "RHEL project" in Red Hat Jira (issue links are of type "https://issues.redhat.com/browse/RHEL-XXXX", where "X" is a digit). This same link will be available in a blue banner at the top of the page informing you that that bug has been migrated.

Description Vojtech Trefny 2021-10-06 13:45:41 UTC 
libblockdev can currently recognize and get information about existing DM integrity (and LUKS2 AEAD) devices but doesn't support creation and activation of these devices. We should add functions do format (bd_crypto_integrity_format) and (de)activate newly created integrity devices (bd_crypto_integrity_open/close) to allow Blivet to add full support for these devices for storage role and installer.

Comment 4 guazhang@redhat.com 2021-12-09 04:03:04 UTC 
Hi

it seem the python module BlockDev  don't include  `bd_crypto_integrity_format` function

>>> hasattr(BlockDev,"bd_crypto_integrity_format")
False


please have a look the bug and share some details what how to call the bd_crypto_integrity_format ?
Comment 5 Vojtech Trefny 2021-12-09 07:55:55 UTC 
The `bd_` prefix from the C functions is replaced by the `BlockDev` module in Python, so `bd_crypto_integrity_format` will become `BlockDev.crypto_integrity_format`:

>>> hasattr(BlockDev, "crypto_integrity_format")
True

Example of formatting, opening and closing a device with integrity:

BlockDev.crypto_integrity_format(<device path>, "sha256", False)
BlockDev.crypto_integrity_open(<device path>, "integritytest", "sha256")
BlockDev.crypto_integrity_info("integritytest")
BlockDev.crypto_integrity_close("integritytest")
Comment 6 guazhang@redhat.com 2021-12-09 12:56:03 UTC 
Hi,

Test pass with fixed package, the function `crypto_integrity_format, crypto_integrity_open, crypto_integrity_info, crypto_integrity_close` work well.
