Title:
IMA significantly increases boot time when enabled
Status in “linux” package in Ubuntu:
Confirmed
Bug description:
I have a TPM-enabled laptop (sudo apt-get install trousers tpm-tools
&& sudo tpm_takeownership) and enabled IMA with the following boot
options in GRUB:
"ima_tcb ima_audit=1 ima_appraise_tcb rootflags=i_version
ima_appraise=fix"
As shown from the attached bootcharts, the boot time goes from circa
25s to circa 225s on an i7, SSD-based system.
