Subject: [PATCH v9 0/7] Support DT_RELR relative relocation format
Date: Thu, 14 Apr 2022 12:04:00 -0700 [thread overview]
Message-ID: <20220414190407.3210003-1-hjl.tools@gmail.com> (raw)
Changes in v9:
1. A DT_RELR shared library without DT_NEEDED works.
2. A DT_RELR shared library without DT_VERNEED works.
3. A DT_RELR shared library without libc.so on DT_NEEDED works.
Changes in v8:
1. Remove the out-of-date comments in _dl_check_map_versions.
2. Change "long" to "long int".
3. Update the DT_RELR NEWS entry.
Changes in v7:
1. Add GLIBC_ABI_DT_RELR support before adding DT_RELR support.
2. Update the DT_RELR NEWS entry.
3. Misc fixes.
Changes in v6:
1. Move ELF_DYNAMIC_DO_RELR before ELF_DYNAMIC_DO_REL.
Changes in v5:
1. Update NEWS entry with the linker option, -z pack-relative-relocs.
2. Remove elf/libc-abi-version.exp and use $(READELF) to check
GLIBC_ABI_DT_RELR.
Changes in v4:
1. Always enable GLIBC_ABI_DT_RELR check.
2. Use $(OBJDUMP) instead of $(NM) for GLIBC_ABI_DT_RELR check.
Changes in v3:
1. Don't define SUPPORT_DT_RELR.
2. Enable DT_RELR in glibc shared libraries and position independent
executables (PIE) automatically if linker supports -z pack-relative-relocs.
Changes in v2:
1. Enable DT_RELR for all targets.
2. Issue an error if there is a DT_RELR entry without GLIBC_ABI_DT_RELR
dependency nor GLIBC_PRIVATE definition.
