we have nt_time_equal doing the same in lib/util/

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.

Office 2003.
Confirmation from reporter that this fixes the issue in master on ext3/ext4.
Back-ports to follow.

ext4 may be able to store ns timestamps, but the only API to *set* timestamps
takes usec, not nsec. Round to usec on set requests.
Jeremy.
|
|
On filesystems that can't store less than one second timestamps,
round the incoming timestamp set requests so the client can't discover
that a time set request has been truncated by the filesystem.
Needs backporting to 3.4, 3.3, 3.2 and (even) 3.0.

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.

AC_CHECK_MEMBERS should be a sufficient check, there's no need to do manual
compile tests. We can also assume that we have ctime and atime members when we
have the mtime member.

the fixed configure check led to a missing semicolon in the now activated BSD
code. Then this error was even copypasted into the new AIX code. grrr

current_timestring used to return a string talloced to talloc_tos().
When called by DEBUG from a TALLOC_FREE, this produced messages
"no talloc stackframe around, leaking memory". For example when
used from net conf.
This also adds a temporary talloc context to alloc_sub_basic().
For this purpose, the exit strategy is slightly altered: a common
exit point is used for success and failure.

bugs in various places whilst doing this (places that assumed

(next checkin).

we have to take care to preserve the "special" values
for Windows of 0x80000000 and 0x7FFFFFFF when casting
between time_t and uint32. Add conversion functions
(and use them).

for utimes - change the call to ntimes. This preserves
nsec timestamps we get from stat (if the system supports
it) and only maps back down to usec or sec resolution
on time set. Looks bigger than it is as I had to move
lots of internal code from using time_t and struct utimebuf
to struct timespec.

0x8000000000000000LL is "infinity" to NT and should
not be converted numerically to time_t.

comparisons here, not unsigned as we're eventually
casting into what it normall a signed 32 bit
value. Guenther please check (but I think I'm right here).

Just try to log on in offline mode without the fix: all accounts are expired,
although they are set to never expire in the PAC/info3.
NTTIME "Never" needs to get (time_t) -1.
We were casting a uint64 to time_t before
comparing, and we should have been doing it
the other way around.
Guenther please check this fixes things.

This completes the work Jeremy began last week, disambiguating the meaning of
c_time. (In POSIX terminology, c_time means "status Change time", not "create
time".) All uses of c_time, a_time and m_time have now been replaced with
change_time, access_time, and write_time, and when creation time is intended,
create_time is used.
Additionally, the capability of setting and retrieving the create time have
been added to the smbc_setxattr() and smbc_getxattr() functions. An example
of setting all four times can be seen with the program
examples/libsmbclient/testacl
with the following command line similar to:
testacl -f -S "system.*:CREATE_TIME:1000000000,ACCESS_TIME:1000000060,WRITE_TIME:1000000120,CHANGE_TIME:1000000180" 'smb://server/share/testfile.txt'
The -f option turns on the new mode which uses full time names in the
attribute specification (e.g. ACCESS_TIME vs A_TIME).

casing too I
think. This broke 'make test' because the newly created user was set to be
kicked off Mi, 22 Jan 1975 23:55:33 CET (unix time 159663333) with the
setuserinfo21 call.
I'm not 100% sure that 0x7ff... means max time as I do it here, I vaguely
remember it to mean "don't touch".
Does anybody know that for sure?
Jeremy, please check this.
Thanks,
Volker
