2011-04-03s3: Fix bug 8042: File creation on OS/XVolker Lendecke1-0/+3
With a case insensitive file system the stat cache lookup leaked the parent directorys stat information from unix_convert into the smb_filename. This led open_file_ntcreate to believe it just created a directory. In the case where we do the search we already invalidate the stat struct. Thanks to TAKAHASHI Motonobu for insisting! :-) Volker Autobuild-User: Volker Lendecke <vlendec@samba.org> Autobuild-Date: Sun Apr 3 14:54:27 CEST 2011 on sn-devel-104

Jeremy.
2010-09-10Factor out the recent changes into a function - check_parent_exists().Jeremy Allison1-77/+103
Fix this to ensure that if "start" is manipulated, then "dirpath" is changed also. Ensures that when the path: /a/long/file/name/path.txt is processed, we first stat: /a/long/file/name/path.txt and if this fails, we try to stat: /a/long/file/name if this path exists (the normal case when creating a new entry in a directory) then we no longer do the individual path name walk, but only do case insensitive lookup on the last component. If the stat fails we do the full pathname walk as normal in 3.5.x and below. Metze, examine this change for your back-port. Jeremy.

2010-04-08Fix bug #7339 - MSDFS is non-functional in 3.5.xJeremy Allison1-0/+2
In the refactoring around filename_convert, the split between the functions resolve_dfspath() and resolve_dfspath_wcard() was lost, leaving us only with resolve_dfspath_wcard(). Internally resolve_dfspath_wcard() calls dfs_redirect() only with a "allow_wcards" flag of true, wheras the old resolve_dfspath() would call with a value of false. The loss of this case causes dfs_redirect to always masquerade DFS links as directories, even when they are being queried directly by a trans2 QPATHINFO call. We should only masquerade DFS links as directories when called from a SMBsearch or trans2 findfirst/findnext - which was the intent of the "allow_wcards" flag. This patch adds back an allow_wcards bool parameter to resolve_dfspath_wcard(). This bool is set from the state of the ucf_flags when filename_convert() is called. I will follow this up with a new smbclient-based torture test that will prevent us from ever regressing our DFS support again. Jeremy.

This way we avoid any chance that a configuration reload may turn back on wide links when unix extensions are enabled.
2009-11-25Make us pass RAW-CHKPATH with a case sensitive share.Jeremy Allison1-42/+105
I know Volker will look at this closely so here's the explaination :-). Originally on a case-sensitive share we simply did a stat (or lstat) call and returned success of fail based on the result. However this failed to take account of incoming paths with a wildcard (which must always fail, and with different error messages depending on whether the wildcard is the last component or in the path). Also it failed to take account of a stat fail with ENOENT due to a missing component of the path as the last component (which is ok as it could be a new file) or if the ENOENT was due to the missing component within the path (not the last component) - which must return the correct error. What this means is that with "case sensitive = yes" we do one more talloc call (to get the parent directory) and one more stat call (on the parent directory) in the case where the stat call fails. I think this is an acceptable overhead to enable case sensitive shares to return the correct error messages for applications. Volker please examine carefully :-). Jeremy.
2009-11-24Remove call into reduce_name if case sensitive. This allows us to passJeremy Allison1-2/+1
RAW-CHKPATH when case sensitive = yes, but isn't the correct way to do it. I'm testing a larger patch to smbd/filename.c that should fix this correctly, and will add a torture test to ensure RAW-CHKPATH is run against a case sensitive share once this is done. Jeremy.

2009-08-28s3: Add a new VFS op called SMB_VFS_TRANSLATE_NAMEAravind Srinivasan1-1/+5
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.

caller know if the path has a wildcard This also eliminates the need for resolve_dfspath().
2009-07-22s3: Change unix_convert to use an smb_filename struct internallyTim Prouty1-137/+154
This allows SMB_VFS_[L]STAT to be called directly. Additionally, I changed NTSTATUS result to be named status for consistency. I also removed the stat_cache_add() from build_stream_path() because stat_cache_lookup() is never actually called on a file with a stream. There is no reason why the stat cache couldn't be consulted for streams in the future. Jeremy/Volker, please take a look at this one when you get a chance.

2009-07-06s3: Add ability to pass NULL to filename_convert for the char *fnameTim Prouty1-7/+11
The goal is to eventually remove the need for the char **fname argument once all callers have standardized on smb_filename.
2009-06-24s3: Plumb smb_filename through SMB_VFS_STAT and SMB_VFS_LSTATTim Prouty1-30/+81
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.
2009-06-19Fix Coverity IDs 922 and 933Volker Lendecke1-2/+5
In copy_internals(), if the !CAN_WRITE(conn) kicks in, we end up dereferencing a NULL smb_filename. This adds a simple protection around it. Tim, please check! Volker
2009-06-18Replace the boilerplate calls to :Jeremy Allison1-0/+52
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.
2009-06-17s3: Change SMB_VFS_OPEN to take an smb_filename structTim Prouty1-3/+2
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.
