Subject: fdopendir (BUG?)
Calling fdopendir with a file descriptor obtained with O_PATH yields a
bad directory stream descriptor (as it should, if I understood
correctly the documentation of open() re O_PATH). However, the call
doesn't fail (it should fail with EBADF). A subsequent call to readdir
(3) detects the error.
(the problem also occurs with glibc, besides the fact that glibc
requires also _GNU_SOURCE to compile, contradicting the linux man
page)
Am I missing something? (Complete test program in attachement, so
that Gmail doesn't crap it.)
Thanks,
Jorge Almeida
