H.J. Lu 6259ab3941 ld.so: Always use MAP_COPY to map the first segment [BZ #30452] ... The first segment in a shared library may be read-only, not executable. To support LD_PREFER_MAP_32BIT_EXEC on such shared libraries, we also check MAP_DENYWRITE to decide if MAP_32BIT should be passed to mmap. Normally the first segment is mapped with MAP_COPY, which is defined as (MAP_PRIVATE | MAP_DENYWRITE). But if the segment alignment is greater than the page size, MAP_COPY isn't used to allocate enough space to ensure that the segment can be properly aligned. Map the first segment with MAP_COPY in this case to fix BZ #30452.		2023-06-30 10:42:42 -07:00
