Subject: [PATCH v5 0/7] Basic recovery for machine checks inside SGX
Date: Fri, 17 Sep 2021 14:38:29 -0700 [thread overview]
Message-ID: <20210917213836.175138-1-tony.luck@intel.com> (raw)
In-Reply-To: <20210827195543.1667168-1-tony.luck@intel.com>
Now version 5.
Changes since v4:
Jarkko Sakkinen:
+ Add linux-sgx@vger.kernel.org to Cc: list
+ Remove explicit struct sgx_va_page *va_page type
from argument and use in sgx_alloc_va_page(). Just
use "void *" as this code doesn't do anything with the
internals of struct sgx_va_page.
+ Drop the union of all possible types for the "owner"
field in struct sgx_epc_page (sorry Dave Hansen, this
went in last time from your comment, but it doesn't
seem to add much value). Back to "void *owner;"
+ rename the xarray that tracks which addresses are
EPC pages from "epc_page_ranges" to "sgx_epc_address_space".
Dave Hansen:
+ Use more generic names for the globally visible
functions that are needed in generic code:
sgx_memory_failure -> arch_memory_failure
sgx_is_epc_page -> arch_is_platform_page
Tony Luck:
+ Found that ghes code spits warnings for memory addresses
that it thinks are bad. Add a check for SGX pages.
Tony Luck (7):
x86/sgx: Provide indication of life-cycle of EPC pages
x86/sgx: Add infrastructure to identify SGX EPC pages
x86/sgx: Initial poison handling for dirty and free pages
x86/sgx: Add SGX infrastructure to recover from poison
x86/sgx: Hook arch_memory_failure() into mainline code
x86/sgx: Add hook to error injection address validation
x86/sgx: Add check for SGX pages to ghes_do_memory_failure()
