Subject: [PATCH 0/2] linux-user: mmap/mprotect prot values
Date: Tue, 19 May 2020 11:56:43 -0700 [thread overview]
Message-ID: <20200519185645.3915-1-richard.henderson@linaro.org> (raw)
The new validation hook will give me a place to add extra
hooks to handle BTI and MTE. But in the meantime, we can
adjust the host page protections to make PROT_EXEC reliable.
