c4f9c37240 s3: smbd: smbd_smb2_setinfo_send(). All calls to SMB_VFS_FSTAT(fsp, &fsp->fsp_name->st) clobber fsp->fsp_name->st.st_ex_iflags.
If doing an SMB_VFS_FSTAT() returning onto the stat struct stored in the fsp,
we must call vfs_stat_fsp() as this preserves the iflags.

This is the last SMB_VFS_FSTAT that uses fsp->fsp_name->st, so
remove knownfail.d/durable-v2-setinfo

280e9191cb smbd: Make non_widelink_open() robust for non-cwd dirfsp
If you pass in dirfsp!=conn->cwd_fsp and a stream fsp, we don't chdir
to the parent pathname, and thus we also don't overwrite
fsp->base_fsp.

fsp->base_fsp!=NULL is thus the wrong condition to restore the
original base fsp name: If we open a stream with a non-cwd_fsp dirfsp,
we would overwrite fsp->base_fsp->fsp_name with NULL.

5fe341d2d6 s3: torture: Add 2 new tests SMB2-DEL-ON-CLOSE-NONWRITE-DELETE-NO, SMB2-DEL-ON-CLOSE-NONWRITE-DELETE-YES.
We currently allow setting the delete on close bit for
a directory containing only explicitly hidden/vetoed files
in the case where "delete veto files = yes" *and*
"delete veto files = no". For the "delete veto files = no"
case we should be denying setting the delete on close bit
when the client tries to set it (that's the only time Windows
looks at the bit and returns an error to the user). We
already do the in the dangling symlink case, we just
missed it in the !is_visible_fsp() case.

Mark SMB2-DEL-ON-CLOSE-NONWRITE-DELETE-NO as knownfail
for now.

4e21be7e89 selftest: Remove duplicate run of rpc.lsa tests against ad_dc as "samba3"
Running these tests twice is a waste (sorry, thas was my choice when
merging s3 and s4 to just run all the tests against the AD DC) and
more importantly means that tests are run in "samba3" mode against
the AD DC, making it difficult to change the tests to expect a different
behaivour against the AD DC compared to the NT4 DC.

To assure that we have not lost tests, I ran:
grep command st/subunit | grep ad_dc| cut -f 2 -d\" | cut -f 2- -d. | sort | uniq -c

The two blocks (for rpc.lsa and rpc.lsa.*) are because the rpc.lsa.*
subtests were not previously run under ncacn_ip_tcp: and this is the
minimal change.

de439cd030 smbd: Return ISLNK from non_widelink_open() in smb_fname
Soon we want to not require stat() calls before entering
openat_pathref_fsp() anymore but rely on the fstat on the O_PATH file
handle (alternatively the call to fstatat(AT_SYMLINK_NOFOLLOW)) done
properly from within fd_openat(). The callers of non_widelink_open()
expect the stat information to be correct in "smb_fname". Copy it in
case of not opening a symlink in the posix case.

e7b933100e smbd: Don't require a valid stat for openat_pathref_fsp()
With the simplifications in non_widelink_open() (don't depend on the
is_directory fsp flag) the main reason for requiring a valid stat
struct in openat_pathref_fsp() is gone. With this change
openat_pathref_fsp() is now capable of being the very first (and
authoritative) name-referencing operation with openat(O_PATH) for a
name.

Without having the stat information around before calling
openat_pathref_fsp(), the call to check_same_dev_ino() becomes
obsolete here.

2bbdaca8da smbd: No need to set O_DIRECTORY in openat_pathref_fsp()
If I read Linux' man 2 open right (and susv4 agrees), O_DIRECTORY is
around to make sure opendir() is not raced against non-directory
files. opendir() needs to make sure the underlying object is actually
a directory. O_DIRECTORY is not required for opening directories in
RDONLY mode, regardless of having O_PATH or not.

At this point in openat_pathref_fsp() we don't care about the type of
the underlying object, we do fstat() and distinguish between files and
directories later according to the mode returned from fstat().

93d2defa42 smbd: Always use O_NONBLOCK in openat_pathref_fsp()
There's no reason why we would ever want to block on open(O_PATH). The
only cases that to me right now seem relevant is oplock breaks and
FIFOs, which can block forever. Oplock breaks don't happen for
O_PATH (hopefully...) but for the non-O_PATH case we don't want to
block either but we do handle this higher up.

We're handling EWOULDBLOCK for the oplock case correctly in
open_file_ntcreate() by setting up polling. So far we haven't done
this for the implicit openat_pathref_fsp() from filename_convert()
yet. But as our kernel oplock implementation lacks in functionality
big time anyway I would rather fail an open with NETWORK_BUSY than to
sit waiting for an oplock break for 30 seconds.

469a7ebf76 smbd: Simplify dos_mode_check_compressed()
btrfs_fget_compression() is the only real implementation of
VFS_GET_COMPRESSION. It does not use the mem_ctx argument, so it seems
unnecessary to do a full malloc()/free() cycle here. Moreover, if this
was actually required, talloc_stackframe() would be more appropriate
these days as deep within the smbd even loop it does not go through
the libc malloc, but just increments a pointer.
