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.

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.
2009-05-20s3: Change unix_convert (and its callers) to use struct smb_filenameTim Prouty1-77/+98
This is the first of a series of patches that change path based operations to operate on a struct smb_filename instead of a char *. This same concept already exists in source4. My goals for this series of patches are to eventually: 1) Solve the stream vs. posix filename that contains a colon ambiguity that currently exists. 2) Make unix_convert the only function that parses the stream name. 3) Clean up the unix_convert API. 4) Change all path based vfs operation to take a struct smb_filename. 5) Make is_ntfs_stream_name() a constant operation that can simply check the state of struct smb_filename rather than re-parse the filename. 6) Eliminate the need for split_ntfs_stream_name() to exist. My strategy is to start from the inside at unix_convert() and work my way out through the vfs layer, call by call. This first patch does just that, by changing unix_convert and all of its callers to operate on struct smb_filename. Since this is such a large change, I plan on pushing the patches in phases, where each phase keeps full compatibility and passes make test. The API of unix_convert has been simplified from: NTSTATUS unix_convert(TALLOC_CTX *ctx, connection_struct *conn, const char *orig_path, bool allow_wcard_last_component, char **pp_conv_path, char **pp_saved_last_component, SMB_STRUCT_STAT *pst) to: NTSTATUS unix_convert(TALLOC_CTX *ctx, connection_struct *conn, const char *orig_path, struct smb_filename *smb_fname, uint32_t ucf_flags) Currently the smb_filename struct looks like: struct smb_filename { char *base_name; char *stream_name; char *original_lcomp; SMB_STRUCT_STAT st; }; One key point here is the decision to break up the base_name and stream_name. I have introduced a helper function called get_full_smb_filename() that takes an smb_filename struct and allocates the full_name. I changed the callers of unix_convert() to subsequently call get_full_smb_filename() for the time being, but I plan to eventually eliminate get_full_smb_filename().
2009-05-09Do not call SMB_VFS_GET_REAL_FILENAME if the name is mangledVolker Lendecke1-6/+11
The GPFS get_real_file name does not know about mangled names. Tim, if onefs does not either, you need this bugfix :-) In case onefs does 8.3 names, we need to pass the mangled flag down to SMB_VFS_GET_REAL_FILENAME to give GPFS a chance say ENOTSUPP and do the fallback.
2009-05-05s3: Fix trans2 path to use case-insensitive stat optimizationtprouty1-6/+34
Often times before creating a file, a client will first query to see if it already exists. Since some systems have a case-insensitive stat that is called from unix_convert, we can definitively return STATUS_NO_SUCH_FILE to the client without scanning the whole directory. This code path is taken from trans2querypathinfo, but trans2findfirst still does a full directory scan even though the get_real_filename (the case-insensitive stat vfs call) can prevent this. This patch adds the get_real_filename call to the trans2find* path, and also changes the vfs_default behavior for SMB_VFS_GET_REAL_FILENAME. Previously, in the absence of a get_real_filename implementation, we would fallback to the full directory scan. The default behavior now returns -1 and sets errno to EOPNOTSUPP. This allows SMB_VFS_GET_REALFILENAME to be called from trans2* and unix_convert.

2008-12-10Pass the get_real_filename operation through the VFSVolker Lendecke1-4/+1
This is done to help file systems that can tell us about the real upper/lower case combination given a case-insensitive file name. The sample I will soon push is the gpfs module (recent gpfs has a get_real_filename function), others might have a similar function to help alleviate the 1million files in a single directory problem. Jeremy, please comment! Thanks, Volker

2008-08-12Fix unix_convert() for "*" after changing map_nt_error_from_unix().Michael Adam1-1/+1
map_nt_error_from_unix() now assumes that it is called in an error path and returns an error even for a given errno == 0. The original behaviour of unix_convert() used the mapping of errno == 0 ==> NT_STATUS_OK to return success through an error path. I think this must have been an oversight, and unix_convert() worked only by coincidence (or because explicitly using the knowledge of the conceptually wrong working of map_nt_error_from_unix(). This patch puts this straight by not interpreting errno == 0 as an error condition and proceeding in that case. Jeremy - please check!

new stream code. (1) In smbd/filename, don't split the name at ':' if we know it's a posix path (this should be parameterized....). (2). When calling posix_mkdir, we get the flag FILE_FLAG_POSIX_SEMANTICS passed to open_directory(). I know for a posix client lp_posix_pathnames should be true (which is checked for in is_ntfs_stream_name() but we have an explicit flag here, so let's use it. Jeremy.

2008-01-19Add streams supportVolker Lendecke1-0/+121
This is the core of the streams support. The main change is that in files_struct there is now a base_fsp pointer that holds the main file open while a stream is open. This is necessary to get the rather strange delete semantics right: You can't delete the main file while a stream is open without FILE_SHARE_DELETE, and while a stream is open a successful unlink of the main file leads to DELETE_PENDING for all further access on the main file or any stream.
