We now require a GnuTLS version that is not impacted for AES-GCM
(fixed in 3.6.11, we require 3.6.13).

ENXIO is returned when trying to openat() a unix domain socket or a
FIFO without anything at the other end. [MS-ERREF] has
ILLEGAL_FUNCTION as "The specified handle is not open to the server
end of the named pipe.", which comes pretty close to me.

Probably not really measurable, but as this is a pretty frequently

cheap to get :-)

This is not really a problem because we call ndr_push from

This allows us to remove a lot of conditionally compiled code and so
know with more certainly that our tests are covering our code-paths.

This removes a lot of inline #ifdef and means this feature is always tested.
We can do this as we have chosen GnuTLS 3.6.13 as the new minimum version.

3 times talloc_zero() and read_symlink_reparse() makes a nice separate

Move filtering of entries, in particular symlinks, fully into
smbd_dirptr_get_entry(). Before, this was hidden in magic code inside
openat_pathref_fsp() and the mode_fn()s. Changing anything file open
code led to changes in very distant code paths because of unforeseen
consequences to directory listing. This change centralizes the
decision what directory entries to show into
smbd_dirptr_get_entry(). It uses openat_pathref_fsp_nosymlink()
without any symlink magic. It might need some tweaking when we also
want to show other special files, but this will hopefully be easier.

Turn it into openat_pathref_fsp_nosymlink() which opens not only
directories but normal files and symlinks too. If it finds a symlink,
return NT_STATUS_STOPPED_ON_SYMLINK and all the metadata we can find:
struct stat_ex plus the symlink target.

With 7bb8af3f74 we already had to tune the error_inject VFS object to filter
out the openat-calls coming from filename_convert_dirfsp&friends. With
the next patch openat() will be called from even more places, and I
don't really see a good way to properly deal with EINTR in all the
places where it can happen. The real case where EINTR is something we
need to handle properly I guess is with kernel oplocks active: open()
waits for another process to give up its kernel oplock, which opens
the window for EINTR to become a valid case to properly take care
of. For all other opens I would be willing to live with the fact that
we just return an error message that might be different from Windows.
To detect that kernel oplock case properly, with O_PATH we have to
look at the /proc/self/fd/<n> reopen or the O_EMPTY_PATH FreeBSD
flavor from inside the error_inject module I guess. But then, the
second time we come around the corner we have to let it pass.
Difficult to properly test, disable the test for now.
