readdir: fix interface to kernel getdents64 function
Issue:
The kernel will pad the entry->d_reclen in a getdents64 call to a
long-word boundary. For very long records, this could exceed the
size of a struct dirent. The mismatch in the size was causing error
paranoid checking code in bionic to fail... thus causing an early
"end" when reading the dirent structures from the kernel buffer.
Test:
ls
mkdir abcdefghijklmnopqrstuvwxyzabcdefghijklmnopqrstuvwxyzabcdefghijklmnopqrstuvwxyzabcdefghijklmnopqrstuvwxyzabcdefghijklmnopqrstuvwxyzabcdefghijklmnopqrstuvwxyzabcdefghijklmnopqrstuvwxyzabcdefghijklmnopqrstuvwxyzabcdefghijklmnopqrstuvwxyzabcdefghijklmnopqrstu
ls
