strict allocation on sparse files. Files opened as POSIX opens are always sparse. Autobuild-User: Jeremy Allison <jra@samba.org> Autobuild-Date: Tue Dec 21 04:12:22 CET 2010 on sn-devel-104

allocation extent without changing end-of-file size. Autobuild-User: Jeremy Allison <jra@samba.org> Autobuild-Date: Tue Dec 21 02:41:24 CET 2010 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.

2009-11-18s3: Do not talloc in readdirVolker Lendecke1-9/+7
This is a hot codepath (called from the stat cache)
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. Jeremy.

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.

2009-07-21s3: Remove unnecessary callers of get_full_smb_filenameTim Prouty1-40/+18
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

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.

2009-06-02Add SMB_VFS_CONNECTPATH operationVolker Lendecke1-0/+8
This is required for the shadow_copy2 module and "wide links = no". The file system snapshots by nature are typically outside of share directory. So the REALPATH result fails the wide links = no test.
2009-05-26Introduce "struct stat_ex" as a replacement for SMB_STRUCT_STATVolker Lendecke1-22/+22
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.
2009-05-18Move down the become_root()/unbecome_root() calls into the VFS modulesVolker Lendecke1-2/+22
The aio_fork module does not need this, as it does not communicate via signals but with pipes. Watching a strace log with those become_root() calls in aio.c is absolutely awful, and it does affect performance.
