Subject: [PATCH v2 00/13] crypto: x86 - avoid absolute references
Date: Wed, 12 Apr 2023 13:00:22 +0200 [thread overview]
Message-ID: <20230412110035.361447-1-ardb@kernel.org> (raw)
This is preparatory work for allowing the x86 kernel to be built as a
PIE executable, which relies mostly on RIP-relative symbol references
from code, as these don't need to be updated when a binary is loaded at
an address different from its link time address.
Most changes are quite straight-forward, i.e., just adding a (%rip)
suffix is enough in many cases. However, some are slightly trickier, and
need some minor reshuffling of the asm code to get rid of the absolute
references in the code.
Tested with CONFIG_CRYPTO_MANAGER_EXTRA_TESTS=y on a x86 CPU that
implements AVX, AVX2 and AVX512.
Changes since v1:
- add missing tags from Thomas Garnier
- simplify AES-NI GCM tail handling and drop an entire permute vector
table (patch #2)
- add a couple of patches to switch to local labels, which removes ~1000
useless code symbols (e.g., _loop0, _loop1, _done etc etc) from
kallsyms
