As a result, the executable ends up being assigned module 2 (and the generation is pointlessly incremented, unlike in digest_phdr for the normal case). For most architectures this is harmless, since TLS linker relaxation will optimise General Dynamic accesses to Initial Exec or Local Exec for executables, but on RISC-V this relaxation does not exist, yet the linker will initialise the tls_index in the GOT with module 1, and at run time the call to __tls_get_addr will fail with: ld-elf.so.1: Can't find module with TLS index 1 Fix this by making map_object use 1 for obj->tlsindex when it's loading the main executable, and don't bother to increment tls_dtv_generation either, matching digest_phdr (though that one is harmless). (Note this also applies to MIPS on stable/13) Reviewed by: kib Fixes: 0fc65b0ab82c ("Make ld-elf.so.1 directly executable.")

If the page size is smaller than common-page-size, rounding up relro_size may incorrectly make some RW pages read-only. GNU ld, gold, and ld.lld ensures p_vaddr+p_memsz is a multiple of common-page-size. While max-page-size >= system the page size, common-page-size can be smaller than the system page size.
