No change in behaviour. Move the check to the more low-level function
file_set_dosmode() to ensure all callers use this consistently.

This added in 49a754b82d to work with stored
itime based File-Ids. Since switching back to purely inode based File-Ids we
can remove this call that primed itime from DOS xattr.

Untested code is broken code... previous_slash() did not return a
pointer to the slash but after it. This went undetected because so far
we never call symlink_target_path() with "unparsed==0". Once we
started doing that, we would find that the "unparsed==0" case actually
puts parent on the "previous slash", not the character behind it.

We know the buffer size up-front, create a struct for that. Also, I
think if we ever hit another /proc pattern this is very likely on a
different OS that could be handled by an #ifdef.

By asking for TEVENT_FD_ERROR we're able to fail early
when a connection to a client is broken.
In that case it does not make any sense to process
pending requests in the recv queue as it's not
possible to deliver the response to the client anyway.

To me these macros hide more than they clarify. In a lot of places we
already directly check for these flags without those macros. Unify
that.
Also, check for the dosmode bits first, lp_map_* is a bit more effort
to evaluate.

If the client requested FILE_OVERWRITE[_IF], we're implicitly adding
FILE_WRITE_DATA to the open_access_mask in open_file_ntcreate(), but for the
access check we're using access_mask which doesn't contain the additional
right, which means we can end up truncating a file for which the user has
only read-only access via an SD.
BUG: https://bugzilla.samba.org/show_bug.cgi?id=15439
Signed-off-by: Ralph Boehme <slow@samba.org>
In the fd_close() fsp->fsp_flags.fstat_before_close code path.
If this is a stream and delete-on-close was set, the
backing object (an xattr from streams_xattr) might
already be deleted so fstat() fails with
NT_STATUS_NOT_FOUND. So if fsp refers to a stream we
ignore the error and only bail for normal files where
an fstat() should still work. NB. We cannot use
fsp_is_alternate_stream(fsp) for this as the base_fsp
has already been closed at this point and so the value
fsp_is_alternate_stream() checks for is already NULL.
Remove knownfail.

Indicate BACKUP_INTENT to vfs_openat(). Why? I have a customer request
who wants to add O_NOATIME in this case to avoid metadata updates when
a backup or virus-checking application comes along.
This does not fully handle BACKUP_INTENT correctly, this would require
become_root() appropriately. We might want to do that later after a
lot of careful security audit, but this patch independently might
already provide some infrastructure for it.

This needs close review. I could not see where we were actually
referencing the original flags in a way that would not be available in
local_flags. The reason for this patch is that I want to pass in
vfs_open_how into open_file(), and the distinction between flags and
local_flags made this significantly harder to understand for me.
The only place where we really used both versions is the DBG_NOTICE in
the last hunk, and this will come back in the next patch.
