Subject: [musl] [PATCH] personality: add missing personality(2) values
Date: Wed, 18 Nov 2020 10:59:31 -0500 [thread overview]
Message-ID: <FA9605B3-0AA9-4B94-B8A0-9966685518D3@trailofbits.com> (raw)
[-- Attachment #1: Type: text/plain, Size: 323 bytes --]
Adds two missing personality(2) personas: UNAME26
and FDPIC_FUNCPTRS.
FDPIC_FUNCPTRS was also missing its corresponding
PER_LINUX_FDPIC value.
This makes musl's personality.h header consistent with
the definitions supplied by glibc's personality.h.
