Subject: [PATCH v3 00/32] RELRO linkmaps
Date: Thu, 07 Dec 2023 11:30:38 +0100 [thread overview]
Message-ID: <cover.1701944612.git.fweimer@redhat.com> (raw)
This is a rebase on top of the current development branch. There were
quite a few conflicts.
Is the struct link_map_private change something we want? (We currently
have different definitions of struct link_map within glibc and for
applications, resulting in conflicting debugging information.) I can
submit that as a separate patch.
Likewise, I'd like to move the dl_rtld_map out of _rtld_global because
it makes the internal GLIBC_PRIVATE ABI more stable. This series
achieves this as a side effect because the link map is now allocated
using the protected memory allocator. But if the entire series can't
land in 2.39, I'd like to submit this separately as well, along with the
“_dl_rtld_map should not exist in static builds” cleanup.
Thanks,
Florian
