Subject: [PATCH v2 00/32] RELRO link maps
Date: Fri, 07 Jul 2023 20:47:26 +0200 [thread overview]
Message-ID: <cover.1688741159.git.fweimer@redhat.com> (raw)
This is a repost with the vDSO bug in elf/tststatic4 fixed, and the NEWS
conflict resolved.
I also ran some experiments on unpatched master with dlopen and
multi-threaded fork, and it's already really broken. (I posted my
simple test case to bug 30619.) Given that, I don't think this is
something I need to address in this series.
Thanks,
Florian
Florian Weimer (32):
support: Add <support/memprobe.h> for protection flags probing
misc: Enable internal use of memory protection keys
elf: Remove _dl_sysdep_open_object hook function
elf: Eliminate second loop in find_version in dl-version.c
elf: In rtld_setup_main_map, assume ld.so has a DYNAMIC segment
elf: Remove version assert in check_match in elf/dl-lookup.c
elf: Disambiguate some failures in _dl_load_cache_lookup
elf: Eliminate alloca in open_verify
Do not export <alloc_buffer.h> functions from libc
elf: Make <alloc_buffer.h> usable in ld.so
elf: Merge the three implementations of _dl_dst_substitute
elf: Move __rtld_malloc_init_stubs call into _dl_start_final
elf: Merge __dl_libc_freemem into __rtld_libc_freeres
elf: Use struct link_map_private for the internal link map
elf: Remove run-time-writable fields from struct link_map_private
elf: Move l_tls_offset into read-write part of link map
elf: Allocate auditor state after read-write link map
elf: Move link map fields used by dependency sorting to writable part
elf: Split _dl_lookup_map, _dl_map_new_object from _dl_map_object
elf: Add l_soname accessor function for DT_SONAME values
elf: _dl_rtld_map should not exist in static builds
elf: Introduce GLPM accessor for the protected memory area
elf: Bootstrap allocation for future protected memory allocator
elf: Implement a basic protected memory allocator
elf: Move most of the _dl_find_object data to the protected heap
elf: Switch to a region-based protected memory allocator
elf: Determine the caller link map in _dl_open
elf: Add fast path to dlopen for fully-opened maps
elf: Use _dl_find_object instead of _dl_find_dso_for_object in dlopen
elf: Put critical _dl_find_object pointers into protected memory area
elf: Add hash tables to speed up DT_NEEDED, dlopen lookups
elf: Use memory protection keys for the protected memory allocator
