2013-08-26smbd: Simplify dropbox special case in unix_convertVolker Lendecke1-6/+23
EACCESS needs special treatment: If we want to create a fresh file, return OBJECT_PATH_NOT_FOUND, so that the client will continue creating the file. If the client wants us to open a potentially existing file, we need to correctly return ACCESS_DENIED. This patch makes this behaviour hopefully a bit clearer than the code before did.

2013-07-09smbd: Fix a profile problemVolker Lendecke1-1/+2
When trying to read a profile, under certain circumstances Windows tries to read with its machine account first. The profile previously written was stored with an ACL that only allows access for the user and not the machine. Windows should get an NT_STATUS_ACCESS_DENIED when using the machine account, making it retry with the user account (which would then succeed). Samba under these circumstances erroneously gives NT_STATUS_OBJECT_PATH_NOT_FOUND, which makes Windows give up and not retry. The reasons is the "dropbox" patch in unix_convert, turning EACCESS on the last path component to OBJECT_PATH_NOT_FOUND. This patch makes the dropbox behaviour only kick in when we are creating a file. I think this is an abstraction violation. unix_convert() should not have to know about the create_disposition, but given that we have pathname resolution separated from the core open code right now this is the best we can do.

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.

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.

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.

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.

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.

2009-07-22s3: 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.
