Roberto Sassu c470dc530c ima: Don't ignore errors from crypto_shash_update() ... commit 60386b854008adc951c470067f90a2d85b5d520f upstream. Errors returned by crypto_shash_update() are not checked in ima_calc_boot_aggregate_tfm() and thus can be overwritten at the next iteration of the loop. This patch adds a check after calling crypto_shash_update() and returns immediately if the result is not zero.
