in the "user.DOSATTRIB" EA. From the docs:
In Samba 3.5.0 and above the "user.DOSATTRIB" extended attribute has been extended to store
the create time for a file as well as the DOS attributes. This is done in a backwards compatible
way so files created by Samba 3.5.0 and above can still have the DOS attribute read from this
extended attribute by earlier versions of Samba, but they will not be able to read the create
time stored there. Storing the create time separately from the normal filesystem meta-data
allows Samba to faithfully reproduce NTFS semantics on top of a POSIX filesystem.
Passes make test but will need more testing.

set_close_write_time().
We were treating a file time set on close as a sticky write time set, and I don't
think it is. I will add a torture test later to RAW-CLOSE to confirm this.
Jeremy.
|
|
"Normal" non truncate writes always cause the timestamp to
be set on close. Once a close is done on a handle this can
reset the sticky write time to current time also.
Updated smbtorture4 confirms this.

Actually I moved split_ntfs_stream_name into torture.c which is the one

create time from the existing timestamps (for systems
that need to do this). Once the write time is changed
via a sticky write, the create time might need to be
recalculated. To do this I needed to add a bool into
struct stat_ex to remember if the st_ex_btime field
was calculated, or read from the OS. Also fixed the
returning of modified write timestamps in the return
from NTCreateX, SMBattr and SMBattrE (which weren't
taking into account the modified timestamp stored
in the open file table). Attempting to fix an issue
with Excel 2003 and offline files. Volker and Metze,
please review.

SMB_VFS_CHFLAGS isn't actually getting the smb_filename struct for now
since it only operates on the basefile. This is the strategy for all
path-based operations that will never actually operate on a stream.
By clarifying the meaning of path based operations that don't take an
smb_filename struct, modules that implement streams such as vfs_onefs
no longer need to implement SMB_VFS_CHFLAGS to ensure it's only called
on the base_name.

change_notify_reply() -> send_nt_replies()

For sync replies it's not a problem, as construct_reply() will send
the response, but for async replies we would not send the reply to the client.
Currently the notify code works arround this manually, so I assume
we didn't have a bug here. But the next commits will simplify
the notify code.

We should also set the error code, when we return no parameters or data.

Fix a couple more unix_convert uses to filename_convert.
Fix bug in acl_group_override() where an uninitialized
struct could be used. Move unix_convert with wildcard
use in SMBsearch reply to boilerplate code.

resolve_dfspath() -> unix_convert() -> get_full_smb_filename() -> check_name()
with a new function filename_convert().
This restores the check_name() calls that had gone missing
since the default create_file was changed. All "standard"
pathname processing now goes through filename_convert().
I'll take a look at the non-standard pathname processing
next. As a benefit, fixed a missing resolve_dfspath()
in the trans2 mkdir call.

This was a little messy because of all of the vfs modules I had to
touch. Most of them were pretty straight forward, but the streams
modules required a little attention to handle smb_filename. Since the
use of smb_filename enables the vfs modules to access the raw,
over-the-wire stream, a little bit of the handling that was being done
by split_ntfs_stream_name has now been shifted into the individual
stream modules. It may be a little more code, but overall it gives
more flexibility to the streams modules, while also allowing correct
stream handling.
|
|
I used the smb_filename struct everywhere that was feasible for the
first pass. There are still some places in this path that need to be
changed to use smb_filename, but this is a good start.
I also:
- Removed fname/path arguments from a few functions that weren't
really using them.
- Added a utility function for detecting whether an smb_filename is a
stream.
|
|
pull the pathname, then call resolve_dfspath(), before unix_convert().
Jeremy.
|
|
|

This step is a requirement to change SMB_VFS_CREATEFILE to take an
smb_filename struct.

This patch introduces
struct stat_ex {
dev_t st_ex_dev;
ino_t st_ex_ino;
mode_t st_ex_mode;
nlink_t st_ex_nlink;
uid_t st_ex_uid;
gid_t st_ex_gid;
dev_t st_ex_rdev;
off_t st_ex_size;
struct timespec st_ex_atime;
struct timespec st_ex_mtime;
struct timespec st_ex_ctime;
struct timespec st_ex_btime; /* birthtime */
blksize_t st_ex_blksize;
blkcnt_t st_ex_blocks;
};
typedef struct stat_ex SMB_STRUCT_STAT;
It is really large because due to the friendly libc headers playing macro
tricks with fields like st_ino, so I renamed them to st_ex_xxx.
Why this change? To support birthtime, we already have quite a few #ifdef's at
places where it does not really belong. With a stat struct that we control, we
can consolidate the nanosecond timestamps and the birthtime deep in the VFS
stat calls.
At this moment it is triggered by a request to support the birthtime field for
GPFS. GPFS does not extend the system level struct stat, but instead has a
separate call that gets us the additional information beyond posix. Without
being able to do that within the VFS stat calls, that support would have to be
scattered around the main smbd code.
It will very likely break all the onefs modules, but I think the changes will
be reasonably easy to do.

This is the first of a series of patches that change path based
operations to operate on a struct smb_filename instead of a char *.
This same concept already exists in source4.
My goals for this series of patches are to eventually:
1) Solve the stream vs. posix filename that contains a colon ambiguity
that currently exists.
2) Make unix_convert the only function that parses the stream name.
3) Clean up the unix_convert API.
4) Change all path based vfs operation to take a struct smb_filename.
5) Make is_ntfs_stream_name() a constant operation that can simply
check the state of struct smb_filename rather than re-parse the
filename.
6) Eliminate the need for split_ntfs_stream_name() to exist.
My strategy is to start from the inside at unix_convert() and work my
way out through the vfs layer, call by call. This first patch does
just that, by changing unix_convert and all of its callers to operate
on struct smb_filename. Since this is such a large change, I plan on
pushing the patches in phases, where each phase keeps full
compatibility and passes make test.
The API of unix_convert has been simplified from:
NTSTATUS unix_convert(TALLOC_CTX *ctx,
connection_struct *conn,
const char *orig_path,
bool allow_wcard_last_component,
char **pp_conv_path,
char **pp_saved_last_component,
SMB_STRUCT_STAT *pst)
to:
NTSTATUS unix_convert(TALLOC_CTX *ctx,
connection_struct *conn,
const char *orig_path,
struct smb_filename *smb_fname,
uint32_t ucf_flags)
Currently the smb_filename struct looks like:
struct smb_filename {
char *base_name;
char *stream_name;
char *original_lcomp;
SMB_STRUCT_STAT st;
};
One key point here is the decision to break up the base_name and
stream_name. I have introduced a helper function called
get_full_smb_filename() that takes an smb_filename struct and
allocates the full_name. I changed the callers of unix_convert() to
subsequently call get_full_smb_filename() for the time being, but I
plan to eventually eliminate get_full_smb_filename().

sbuf as invalid (if not already read via stat()). Still trying

We keep the seqnum/mid mapping in the smb_request structure.
This also moves one global variable into the
smbd_server_connection struct.
metze

[MS-SMB] 3.3.5.1 Receiving Any Message says that the seqnum
is incremented by only for ntcancel requests for any other
request it's by incremented by 2, even if it doesn't expect
a response.

This extends the file_id struct to add an additional generic uint64_t
field: extid. For backwards compatibility with dev/inodes stored in
xattr_tdbs and acl_tdbs, the ext id is ignored for these databases.
This patch should cause no functional change on systems that don't use
SMB_VFS_FILE_ID_CREATE to set the extid.
Existing code that uses the smb_share_mode library will need to be
updated to be compatibile with the new extid.
|
|
This changelist allows for the addition of custom performance
monitoring modules through smb.conf. Entrypoints in the main message
processing code have been added to capture the command, subop, ioctl,
identity and message size statistics.
|
|
This allows module implementors to customize what allocation size is
returned to the client.
