Subject: Can I use la_symbind to change the shared object file where it's binded?
Date: Thu, 6 Oct 2022 10:05:38 -0700 [thread overview]
Message-ID: <CAH4OOv62xN=WXUC8qCXDOwr_6Ejme9HS-rag0xjViqHzEhJYtQ@mail.gmail.com> (raw)
Hello!
I am looking to see if I can replicate LD_PRELOAD using la_symbind in
the rltd-audit API.
I would like to provide the audit API a: symbol -> shared object file
(perhaps with offset) and have the audit API override it.
Is this possible?
I am thinking perhaps I can dlopen the file in the audit method and
then use dlsym as well.
(Hopefully this question makes sense and appreciate any advice)
