Merge tag 'integrity-v6.16' of git://git.kernel.org/pub/scm/linux/kernel/git/zohar/linux-integrity
Pull integrity updates from Mimi Zohar: "Carrying the IMA measurement list across kexec is not a new feature, but is updated to address a couple of issues: - Carrying the IMA measurement list across kexec required knowing apriori all the file measurements between the "kexec load" and "kexec execute" in order to measure them before the "kexec load". Any delay between the "kexec load" and "kexec exec" exacerbated the problem. - Any file measurements post "kexec load" were not carried across kexec, resulting in the measurement list being out of sync with the TPM PCR. With these changes, the buffer for the IMA measurement list is still allocated at "kexec load", but copying the IMA measurement list is deferred to after quiescing the TPM. Two new kexec critical data records are defined" * tag 'integrity-v6.16' of git://git.kernel.org/pub/scm/linux/kernel/git/zohar/linux-integrity: ima: do not copy measurement list to kdump kernel ima: measure kexec load and exec events as critical data ima: make the kexec extra memory configurable ima: verify if the segment size has changed ima: kexec: move IMA log copy from kexec load to execute ima: kexec: define functions to copy IMA log at soft boot ima: kexec: skip IMA segment validation after kexec soft reboot kexec: define functions to map and unmap segments ima: define and call ima_alloc_kexec_file_buf() ima: rename variable the seq_file "file" to "ima_kexec_file"
