| |
Cause the fall through in do_mmap (around mm/mmap.c:223) all kind of file mmap are denied with EACCES if file is not open for reading. This is contrary to mmap(2):
ERRORS ... EACCES MAP_PRIVATE was asked, but fd is not open for read- ing. Or MAP_SHARED was asked and PROT_WRITE is set, fd is not open for writing.
As I'm unable to understand why a file opened WR_ONLY cannot be mmap'ed PROT_WRITE, MAP_SHARED I deduce that a break is missing at line 222.
Another for me incomprehensible option is that mmap(2) is wrong... can someone clarify this?
