2010-12-01s3: Attempt to fix the shadow_copy2 moduleVolker Lendecke1-2/+2
This module is from hell. Please make 100% sure that you did test it properly when touching it! This module has probably given me more grey hair than any other piece of Samba, so PLEASE PLEASE PLEASE be careful here!!!
2010-11-20Move the uglyness of #ifdef REALPATH_TAKES_NULL into the vfs_defaultJeremy Allison1-3/+3
module, change the signature of VFS_REALPATH to always return a malloc'ed string. Needed to make some privileges work I plan on doing shortly easier to code. Jeremy. Autobuild-User: Jeremy Allison <jra@samba.org> Autobuild-Date: Sat Nov 20 02:15:50 CET 2010 on sn-devel-104

2010-08-04fix snapshot content display with hide unreadableChristian Ambach1-1/+8
With the hide unreadable option set, snapshots are be displayed as empty with shadow_copy2 and a NFSv4 ACL module. To prevent multiple conversions of the paths when the acl call does a VFS_STAT (as the nfs4acl code does), a check was added to convert_shadow2_name() so it will not touch paths any more that look like they have already been converted.

2009-07-29shadow_copy2: The system getrealfilename() can't deal with a 0-length fnameVolker Lendecke1-0/+3
This fixes viewing the content of snapshots in the share root directory. We have to treat the filename that *just* consists of "@GMT-YYYY.MM.DD-HH.MM.SS" like the share root, which is the current working directory.

2009-06-24s3: Plumb smb_filename through SMB_VFS_STAT and SMB_VFS_LSTATTim Prouty1-4/+8
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/+29
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 a "connectpath" operation to the shadow_copy2 moduleVolker Lendecke1-0/+54
2009-05-26Introduce "struct stat_ex" as a replacement for SMB_STRUCT_STATVolker Lendecke1-1/+1
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.
2009-04-28Fix annoying debug messages when no snapshots are usedVolker Lendecke1-2/+3
Not being able to open the shadow copy directory is the same as having no shadow copy support at all. The VFS module should in this case not log with debug level 0 and set ENOSYS to indicate "no shadow copies used" to the higher levels.
2009-02-09Add an optional SMB_STRUCT_SMB parameter to VFS_OP_READDIRSteven Danneman1-1/+1
* this allows VFS implementations that prefetch stat information on readdir to return it through one VFS call * backwards compatibility is maintained by passing in NULL * if the system readdir doesn't return stat info, the stat struct is set to invalid
2009-01-23Extend NTIMES to allow setting create_timetodd stecher1-2/+2
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.
2008-05-08Yay ! Remove a VFS entry. Removed the set_nt_acl() call,Jeremy Allison1-8/+0
this can only be done via fset_nt_acl() using an open file/directory handle. I'd like to do the same with get_nt_acl() but am concerned about efficiency problems with "hide unreadable/hide unwritable" when doing a directory listing (this would mean opening every file in the dir on list). Moving closer to rationalizing the ACL model and maybe moving the POSIX calls into a posix_acl VFS module rather than having them as first class citizens of the VFS. Jeremy.

2008-01-16Merge a variant of Shadow Copy module for exposing snapshots to windows ↵Alexander Bokovoy1-0/+637
clients as shadow copies from Samba 3.0 CTDB This is a 2nd implemetation of a shadow copy module for exposing snapshots to windows clients as shadow copies. This version has the following features: 1) you don't need to populate your shares with symlinks to the snapshots. This can be very important when you have thousands of shares, or use [homes] 2) the inode number of the files is altered so it is different from the original. This allows the 'restore' button to work without a sharing violation Signed-off-by: Alexander Bokovoy <ab@samba.org>(This used to be commit 10c2ae1efd799b44255ce82c3bb0c7c9df0ec634)
