Subject: [PATCH 2/2] aarch64: Make glibc.mem.tagging SXID_ERASE
Date: Tue,  3 Oct 2023 16:11:51 -0400	[thread overview]
Message-ID: <20231003201151.1406279-3-siddhesh@sourceware.org> (raw)
In-Reply-To: <20231003201151.1406279-1-siddhesh@sourceware.org>

Limit effect of memory tagging to the same process and don't let it
bleed across privilege boundaries into non-setuid children of setuid
processes.
