Subject: [musl] RELRO vs deferred binding
Date: Wed, 31 Mar 2021 17:27:09 +0300 (MSK) [thread overview]
Message-ID: <alpine.LNX.2.20.13.2103311716370.2351@monopod.intra.ispras.ru> (raw)
Hi,
my understanding is that deferred binding currently does not work if any of the
deferred relocations fall into the RELRO segment.
I am raising this because Alpine may try enabling -fno-plt globally, and
with -fno-plt non-PLT GOT relocations will be in RELRO, and affected Xorg
modules will fail to load, again, but now with a segfault in the dynamic
linker, presumably (I have not tested this).
Alexander
