This looks innocent, but it is visible in a netbench run. Due to boolean
short-circuiting we don't have to execute the conditions on the right-hand side
of the &&. So putting the less likely condition left gains a bit.
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.

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.

This vop is designed to work in tandem with SMB_VFS_READDIR to allow
vfs modules to make modifications to arbitrary filenames before
they're consumed by callers. Subsequently the core directory
enumeration code in smbd is now changed to free the memory that may be
allocated in a module. This vop enables the new version of catia in
the following patch.

W2K3 DC's can have IPv6 addresses but won't serve
krb5/ldap or cldap on those addresses. Make sure when
we're asking for DC's we prefer IPv4.
If you have an IPv6-only network this prioritizing code
will be a no-op. And if you have a mixed network then you
need to prioritize IPv4 due to W2K3 DC's.
Jeremy.
This patch also changes the unix convert flags to make sure the
correct semantics are preservered for allowing/disallowing wildcards
in the last component of the path.
This often times means explicitly denying certain operations on a stream
as they are not supported or don't make sense at a particular level. At
some point in the future these can be enabled, but for now it's better to
remove ambiguity
The values of vuid and tid were not being correctly updated in the struct smb_request
when passed to chain_reply inside sessionsetupX and tconX.

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.
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.
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.
Jeremy.
