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.
This patch introduces two new temporary helper functions
vfs_stat_smb_fname and vfs_lstat_smb_fname. They basically allowed me
to call the new smb_filename version of stat, while avoiding plumbing
it through callers that are still too inconvenient. As the conversion
moves along, I will be able to remove callers of this, with the goal
being to remove all callers.
There was also a bug in create_synthetic_smb_fname_split (also a
temporary utility function) that caused it to incorrectly handle
filenames with ':'s in them when in posix mode. This is now fixed.
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.
Jeremy.
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.
1) Add in smb_file_time struct to clarify code and make room for createtime.
2) Get and set create time from SMB messages.
3) Fixup existing VFS modules + examples Some OS'es allow for the
setting of the birthtime through kernel interfaces. This value is
generically used for Windows createtime, but is not settable in the
code today.
Some filesystems have support for storing dos attributes directly in
the inode's st_flags and accessing them through the stat struct. This
patch:
- Adds a configure check to see if the special flags are available.
- Implements getting and setting dos attributes in the stat struct and
inode, respectively.
This will not change the existing functionality of any system that
doesn't have the special flags available.
Ok, here's the fix for the write times breakage
with the new tests in S4 smbtorture.
The key is keeping in the share mode struct
the "old_file_time" as the real write time,
set by all the write and allocation calls,
and the "changed_write_time" as the "sticky"
write time - set by the SET_FILE_TIME calls.
We can set them independently (although I
kept the optimization of not setting the
"old_file_time" is a "changed_write_time"
was already set, as we'll never see it.
This allows us to update the write time
immediately on the SMBwrite truncate case,
SET_END_OF_FILE and SET_ALLOCATION_SIZE calls,
whilst still have the 2 second delay on the
"normal" SMBwrite, SMBwriteX calls.
I think in a subsequent patch I'd like to
change the name of these from "old_file_time"
to "write_time" and "changed_write_time" to
"sticky_write_time" to make this clearer.
I think I also fixed a bug in Metze's original
code in that once a write timestamp had been
set from a "normal" SMBwriteX call the fsp->update_write_time_triggered
variable was set and then never reset - thus
meaning the write timestamp would never get
updated again on subsequent SMBwriteX's.
The new code checks the update_write_time_event
event instead, and doesn't update is there's
an event already scheduled.
Metze especially, please check this over for
your understanding.
Jeremy.
(This used to be commit 6f20585419)
We now never call file_ntimes() directly, every update
is done via smb_set_file_time().
This let samba3 pass the BASE-DELAYWRITE test.
The write time is only updated 2 seconds after the
first write() on any open handle to the current time
(not the time of the first write).
Each handle which had write requests updates the write
time to the current time on close().
If the write time is set explicit via setfileinfo or setpathinfo
the write time is visible directly and a following close
on the same handle doesn't update the write time.

(This used to be commit 2eab212ea2)
Dos mode calculation was masking out FILE_ATTRIBUTE_OFFLINE so that code to set file offline
was never called before. Merge from Tridge's v3-0-ctdb git tree.
(This used to be commit 9827d5ff41)
This makes sense as upper levels are only taking returned result of 0
(no error) into consideration when deciding whether to mark file
offline/online as returned from is_offline.
That means that we simply can move the decision down to VFS module and
clean up upper levels so that they always see only file status. If there
is an error when trying to identify file status, then VFS module could
decide what to return (offline or online) by itself -- after all, it
ought to have system-specific knowledge anyway.
(This used to be commit 75cc086614)
Offline files support and remote storage are for allowing communication with
backup and archiving tools that mark files moved to a tape library as offline.
We translate this info into corresponding CIFS offline file attribute and
mark an exported volume as remote storage.
Async I/O force is to allow selective redirection of I/O operations to asynchronous
processing in case it is viable at VFS module discretion. It is needed for
proper handling of offline files as performing regular I/O on offline file will
block smbd.

This fixes a make test failure on Solaris. When creating a new file,
file_set_dosmode() called from open_file_ntcreate calculates a new permission
mask, very likely different from what had been calculated in
open_file_ntcreate. Further down we overwrote the newly calculated value with
SMB_FCHMOD_ACL, ignoring what file_set_dosmode had calculated.
Why did Linux not see this? fchmod_acl on a newly created file without acls
would not retrieve an acl at all, whereas under Solaris acl(2) returns
something even for files with just posix permissions returns something.
Jeremy, given that we have very similar code in 3.0.28 this might also explain
some of the bug reports that people have concerning ACLs on new files.

for utimes - change the call to ntimes. This preserves
nsec timestamps we get from stat (if the system supports

to struct timespec.

If yes: map inverse of user "w" bit to mean readonly.
If no: never set DOS readonly bit.

If store dos attributes is set to yes then this parameter
is ignored.

(This used to be commit c381d32e3d)
bit file interface for the NT SMB's.
Created a new define, SMB_STRUCT_STAT that currently is
defined to be struct stat - this wil change to a user
defined type containing 64 bit info when the correct
wrappers are written for 64 bit stat(), fstat() and lstat()
calls.
Also changed all sys_xxxx() calls that were previously just
wrappers to the same call prefixed by a dos_to_unix() call
into dos_xxxx() calls. This makes it explicit when a pathname
translation is being done, and when it is not.
Now, all sys_xxx() calls are meant to be wrappers to mask
OS differences, and not silently converting filenames on
the fly.

rather than the very complex user/group permissions checks we do
currently. This is equivalent ot setting "alternate permissions = yes"
in the old code. The change is motivated by three main reasons:
1) it's basically impossible to second guess whether a file is
writeable without trying to open it for writing. ACLs, root squash etc
just make it too hard.
2) setting it not RONLY if the owner can write is closer to what NT
does (eg. look at a cdrom - files are not marked read only).
3) it prevents the silly problem of copying files from a read only
share to a writeable share and then finding you can't write to them as
windows preserves the RONLY flag. Lots of people get bitten by this
when they drag a folder from a Samba drive. It also hurts some install
programs.
I have also added a new flag type for loadparm.c called
FLAG_DEPRECATED which I've set for "alternate permissions". I'll soon
add code to testparm to give a warning about deprecated options.
(This used to be commit c4363a12fd)
the splitup was done with an axe, not a scalpel, so there are some
rough edges. I mostly wanted to get the general form right with fine
tuning of what goes where to come later. Still, this is better than
what we had before where server.c was a general repository for
anything that didn't fit elsewhere.
