BLK_INTEGRITY_COMPAR(9) Block Devices BLK_INTEGRITY_COMPAR(9)NAME
blk_integrity_compare - Compare integrity profile of two disks
SYNOPSIS
int blk_integrity_compare(struct gendisk * gd1, struct gendisk * gd2);
ARGUMENTS
gd1
Disk to compare
gd2

DESCRIPTION
Meta-devices like DM and MD need to verify that all sub-devices use the same integrity format before advertising to upper layers that they
can send/receive integrity metadata. This function can be used to check whether two gendisk devices have compatible integrity formats.

gss_unwrap - verify a message with attached message integrity code (MIC) and decrypt message content if necessary
SYNOPSIS DESCRIPTION
The routine converts a protected message to a usable form and verifies the embedded message integrity code (MIC). The conf_state parameter
indicates whether the message was encrypted. The qop_state parameter indicates the quality of protection that was used to provide the con-
fidentiality and integrity services.
Input Parameters
context_handle Specifies the context on which the message arrived.
input_message_buffer Specifies the protected message.
output_message_buffer Specifies the buffer to receive the unwrapped message.
Output Parameters
conf_state Returns the requested level of confidentiality and integrity services, as follows:
Non-zero Both confidentiality and integrity services were used.
zero Only integrity services was used.
qop_state Returns the cryptographic algorithm, or quality of protection.
minor_status Returns a status code from the security mechanism.
STATUS CODES
The following status codes can be returned:
The routine was completed successfully.
The signature was incorrect.
The context has already expired.
The context is recognized but the associated
credentials have expired.
The token failed consistency checks.
The token was valid and contained the correct
signature but it had already been processed.
The routine failed. The context specified in the context_handle parameter was not valid.
The context identified in the
context_handle parameter was not valid.
The token was valid and contained the correct signature
but it is too old.
The token was valid, and contained a correct MIC
for the message, but has been verified out of sequence; a later token has already been received.
The token was valid, and contained a correct MIC
for the message, but has been verified out of sequence; an earlier expected token has not yet been received.
