Subject: [RFC PATCH 0/3] implement dlmopen hooks for gdb
Date: Fri, 26 Jun 2020 12:32:25 -0700 [thread overview]
Message-ID: <20200626193228.1953-1-danielwa@cisco.com> (raw)
Cisco System, Inc. has a need to have dlmopen support in gdb, which
required glibc changes. I think it was known when glibc implemented
dlmopen that gdb would not work with it.
Since 2015 Cisco has had these patches in our inventor to fix issues in
glibc which prevented this type of gdb usage.
This RFC is mainly to get guidance on this implementation. We have some
individuals who have signed the copyright assignment for glibc, and we
will submit these (or different patches) formally thru those channels if
no one has issues with the implementation.
Also included in this are a couple of fixes which went along with the
original implementation.
Please provide any comments you might have.
Conan C Huang (3):
Segfault when dlopen with RTLD_GLOBAL in dlmopened library
glibc: dlopen RTLD_NOLOAD optimization
add r_debug multiple namespaces support
