2009-05-26Introduce "struct stat_ex" as a replacement for SMB_STRUCT_STATVolker Lendecke1-15/+13
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 Prouty1-36/+54
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().
2009-03-25Ensure we never enter VFS_CREATE without having initializedJeremy Allison1-0/+4
sbuf as invalid (if not already read via stat()). Still trying to find the build farm RAW-STREAM errors and it's happening in a openX call.... Jeremy.
2009-03-23s3:smbd: use new simplified snb_signing code in the serverStefan Metzmacher1-1/+2
We keep the seqnum/mid mapping in the smb_request structure. This also moves one global variable into the smbd_server_connection struct. metze
2009-03-06s3:signing: the seqnum should only be decremented by 1 for ntcancel requestsStefan Metzmacher1-1/+1
[MS-SMB] 3.3.5.1 Receiving Any Message says that the seqnum is incremented by only for ntcancel requests for any other request it's by incremented by 2, even if it doesn't expect a response. metze
2009-02-19s3: Add extid to the dev/inode pairTim Prouty1-0/+2
This extends the file_id struct to add an additional generic uint64_t field: extid. For backwards compatibility with dev/inodes stored in xattr_tdbs and acl_tdbs, the ext id is ignored for these databases. This patch should cause no functional change on systems that don't use SMB_VFS_FILE_ID_CREATE to set the extid. Existing code that uses the smb_share_mode library will need to be updated to be compatibile with the new extid.
2009-02-09S3: New module interface for SMB message statistics gatheringtodd stecher1-1/+7
This changelist allows for the addition of custom performance monitoring modules through smb.conf. Entrypoints in the main message processing code have been added to capture the command, subop, ioctl, identity and message size statistics.
2009-01-29s3: Add a new SMB_VFS_GET_ALLOC_SIZE vfs operationTim Prouty1-2/+2
This allows module implementors to customize what allocation size is returned to the client.

2009-01-11s3: Differentiate between posix files with colons and actual streamsTim Prouty1-2/+34
It is possible for a posix file created locally or over nfs to have a ":" in the name. Since ":" is a reserved character in windows, filenames containing a colon must be mangled in a directory listing. Right now files containing colons will not even be displayed in directory listings if streams modules are in use. During the directory listing the file will be detected as a stream because of the colon, but the streams module will fail to find the stream since it doesn't exist. This fix adds a step to is_ntfs_stream_name that stats the filename to differentiate between actual streams and files containing colons. While this is an improvement, it isn't perfect. Consider the case where there is a file on disk called "a.txt:s1" and also a file called "a.txt" that has a stream called "s1". This patch will always preference "a.txt:s1" over a.txt's s1 stream. The real issue is that at the vfs level, the vfs modules have no way to tell between a demangled name with a colon and an actual stream. A more invasive, but better, long-term fix would be to add all paths that come over the wire into a struct containing metadata about the path. This metadata could include a flag to indicate whether the path came over the wire with a colon ":" (guaranteeing that the client is requesting a stream). Passing this struct down to the lower levels, including all path-based vfs calls, would allow the above case to be handled correctly in all cases.

2008-12-03s3: Change SMB_VFS_CREATE_FILE to take a create_file_flags argumentTim Prouty1-4/+4
This replaces the is_dos_path bool with a more future-proof argument. The next step is to plumb INTERNAL_OPEN_ONLY through this flag instead of overridding the oplock_request.
2008-12-03s3: Modify direct callers of open_file_ntcreate and open_directory to call ↵Tim Prouty1-16/+38

2008-12-03s3: Add new "is_dos_path" argument to SMB_VFS_CREATE_FILETim Prouty1-0/+2
Now unix paths can be differentiated from windows paths so the underlying create_file implementations can convert paths correctly.
2008-12-03s3: Add SMB_VFS_CREATE_FILE to the vfs layerTim Prouty1-8/+34
Modify all callers of create_file to go through SMB_VFS_CREATE_FILE
2008-11-30Set PRESENT flag when returning NULL [SD]ACL like Windows does.Steven Danneman1-1/+9
This could also be handled inside each ACL VFS module, by setting the PRESENT flag when a NULL [SD]ACL is created.
2008-11-28Remove "conn" parameter from np_open, smb_request contains itVolker Lendecke1-1/+1
2008-11-28Consolidate the buffer checks for the reply_trans style functionsVolker Lendecke1-57/+18
This is the one where I found the problem that led to 3.2.5. So if there is one checkin in the last year that I would like others to review and *understand*, it is this one :-) Volker
2008-11-28Remove the variable "size" from reply_nttransVolker Lendecke1-10/+13
This converts the range checks for the setup[] array to rely on req->wct being set correctly in init_smb_request. As that already verifies the vwv array to be in the range of the smb_request inbuf, we don't have to do overflow checks here anymore. Jeremy, please check thoroughly! :-) Thanks, Volker
2008-11-27Fix the offset checks in the trans routinesVolker Lendecke1-3/+3
This fixes a potential crash bug, a client can make us read memory we should not read. Luckily I got the disp checks right... Volker (cherry picked from commit 64a1d80851da5b05e70ec6c96f6e9bd473748369) (cherry picked from commit f04c5650a3aeca23591ddc781c4b297caaf9bb3f)
2008-11-23Fix to allow setting of NULL DACL/SACLSteven Danneman1-11/+2
This is a modification of Jeremy's 7522ef15aca2429ef57c75d8297dd8121e79c9da commit. If no DACL/SACL is present in the packet, the SEC_INFO field should still be passed down as is to the VFS layer to signal the creation of a NULL DACL/SACL. As seen in metze RAW-ACL test_nttrans_create_null_dacl(), a NULL DACL is set regardless of the SEC_DESC_DACL_PRESENT bit being set.

2008-10-08For the vfs_acl_xattr.c module, make sure we map GENERIC file and directory bitsJeremy Allison1-0/+5
to specific bits every time a security descriptor is set. The S4 torture suite proves that generic bits are not returned when querying an ACL set using them (ie. only the specific bits are stored on disk). Jeremy.

2008-09-08Fix calculation of useable_space for trans2 and nttrans repliesVolker Lendecke1-12/+10
When alignment was in place, we pretended to send more data/params according to the param_offset/param_length and data_offset/data_length parameters than would actually fit into the SMB according to the NBSS length field. (This used to be commit ef3c132b8455c6fe4d0bb9f0be881040a806a4ed)
