The expectation is that any property |handling for the main executable will be done by the interpreter. This is |a bit inconsistent since we do map the executable and is causing problems |for the arm64 BTI support when used in conjunction with systemd's use of |seccomp to implement MemoryDenyWriteExecute which stops the dynamic linker |adjusting the permissions of executable segments. | |Allow architectures to handle properties for both the dynamic linker and |main executable, adjusting arch_parse_elf_properties() to have an is_interp |flag as with arch_elf_adjust_prot() and calling it for both the main |executable and any intepreter. | |Signed-off-by: Mark Brown |--- | arch/arm64/include/asm/elf.h | 3 ++- | fs/binfmt_elf.c | 25 +++++++++++++++++-------- | include/linux/elf.h | 4 +++- | 3 files changed, 22 insertions(+), 10 deletions(-) | |diff --git a/arch/arm64/include/asm/elf.h b/arch/arm64/include/asm/elf.h |index 8d1c8dcb87fd..c8678a8c36d5 100644 |--- a/arch/arm64/include/asm/elf.h |+++ b/arch/arm64/include/asm/elf.h -------------------------- No file to patch.
