2011-02-01s3: Fix bug 7940 -- fall back for utimes callsVolker Lendecke1-4/+14
There are systems where ./configure has detected advanced utimes calls which are then not available on other kernels. We should do a proper fallback. Autobuild-User: Volker Lendecke <vlendec@samba.org> Autobuild-Date: Tue Feb 1 22:37:35 CET 2011 on sn-devel-104

2010-12-18Rename vfs operation posix_fallocate to just fallocate and add the ↵Jeremy Allison1-9/+17
vfs_fallocate_mode parameter. It turns out we need the fallocate operations to be able to both allocate and extend filesize, and to allocate and not extend filesize, and posix_fallocate can only do the former. So by defining the vfs op as posix_fallocate we lose the opportunity to use any underlying syscalls (like Linux fallocate) that can do the latter as well. We don't currently use the non-extending filesize call, but now I've changed the vfs op definition we can in the future. For the moment simply map the fallocate op onto posix_fallocate for the VFS_FALLOCATE_EXTEND_SIZE case and return ENOSYS for the VFS_FALLOCATE_KEEP_SIZE case. Jeremy.

2010-03-08s3: remove cross-device rename support from vfs_defaultBjörn Jacke1-116/+0
cross-device rename support has some major limitations: - on huge files clients will timeout or hang - ACLs and EA information is not retained Usually a client will have to handle this. A Windows Server with a reparse point will also just return NT_STATUS_NOT_SAME_DEVICE. We will now by default do the same. I will add a vfs module which will restore the old cross-device renames.
2010-03-05Fix for bug #7189 - Open txt files with notepad on samba shares creates problem.Jeremy Allison1-1/+3
Ensure we don't use any of the create_options for Samba private use. Add a new parameter to the VFS_CREATE call (private_flags) which is only used internally. Renumber NTCREATEX_OPTIONS_PRIVATE_DENY_DOS and NTCREATEX_OPTIONS_PRIVATE_DENY_FCB to match the S4 code). Rev. the VFS interface to version 28. Jeremy.

this function is only called when strict alloc is set, no reason to check that twice.
2009-12-02s3: prefer posix_fallocate for doing "strict allocate"Björn Jacke1-4/+21
posix_fallocate is more efficient than manual zero'ing the file. When preallocation in kernel space is supported it's extremely fast. Support for preallocation at fs layer via posix_fallocate and fallocate at kernel site can be found in Linux kernel 2.6.23/glibc 2.10 with ext4, XFS and OCFS2. Other systems that I know of which support fast preallocation in kernel space are AIX 6.1 with JFS2 and recent Solaris versions with ZFS maybe UFS2, too. People who have a system with preallocation in kernel space might want to set "strict allocate = yes". This reduces file fragentation and it's also safer for setups with quota being turned on. As of today most systems still don't have preallocation in kernel space, and that's why "strict allocate = no" will stay the default for now.

2009-11-17Remove "store create time" code, cause create time to be storedJeremy Allison1-3/+1
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.

2009-11-04s3: add support for full windows timestamps resolution on filesBjörn Jacke1-6/+13
setting nanosecond timestamps using utimensat() was first supported by Linux kernel 2.6.22 and glibc 2.6. It's specified in POSIX.1-2008. This effectively makes us use Windows' full 100ns timestamp resolution - actually just an improvement from 10^-6 to 10^-7. For now Linux CIFS vfs will also just be able to make use of 100ns resolution, not 1ns.

2009-08-28s3: Add a new VFS op called SMB_VFS_TRANSLATE_NAMEAravind Srinivasan1-0/+11
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.

2009-06-24s3: Plumb smb_filename through SMB_VFS_STAT and SMB_VFS_LSTATTim Prouty1-5/+33
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.
2009-06-17s3: Change SMB_VFS_OPEN to take an smb_filename structTim Prouty1-2/+20
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.
