Build Update for openssl/openssl ------------------------------------- Build: #38802 Status: Errored
Duration: 1 hr, 6 mins, and 13 secs Commit: 2621751 (master) Author: Ard Biesheuvel Message: aes/asm/aesv8-armx.pl: avoid 32-bit lane assignment in CTR mode ARM Cortex-A57 and Cortex-A72 cores running in 32-bit mode are affected by silicon errata #1742098 [0] and #1655431 [1], respectively, where the second instruction of a AES instruction pair may execute twice if an interrupt is taken right after the first instruction consumes an input register of which a single 32-bit lane has been updated the last time it was modified. This is not such a rare occurrence as it may seem: in counter mode, only the least significant 32-bit word is incremented in the absence of a carry, which makes our counter mode implementation susceptible to these errata. So let's shuffle the counter assignments around a bit so that the most recent updates when the AES instruction pair executes are 128-bit wide.
