2009-05-30Fix bug #6421 - POSIX read-only open fails on read-only shares.Jeremy Allison1-5/+9
The change to smbd/trans2.c opens up SETFILEINFO calls to POSIX_OPEN only. The change to first smbd/open.c closes 2 holes that would have been exposed by allowing POSIX_OPENS on readonly shares, and their ability to set arbitrary flags permutations. The O_CREAT -> O_CREAT|O_EXCL change removes an illegal combination (O_EXCL without O_CREAT) that previously was being passed down to the open syscall. Jeremy.

2009-05-26Introduce "struct stat_ex" as a replacement for SMB_STRUCT_STATVolker Lendecke1-52/+52
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 Prouty1-41/+87
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().
2009-05-18s3: Always allocate memory in dptr_ReadDirNameAravind Srinivasan1-4/+18
This is a follow up to 69d61453df6019caef4e7960fa78c6a3c51f3d2a to adjust the API to allow the lower layers allocate memory. Now the memory can explicitly be freed rather than relying on talloc_tos(). Signed-off-by: Tim Prouty <tprouty@samba.org>
2009-04-14Rework Samba3 to use new libcli/auth code (partial)Andrew Bartlett1-0/+1
This commit is mostly to cope with the removal of SamOemHash (replaced by arcfour_crypt()) and other collisions (such as changed function arguments compared to Samba3). We still provide creds_hash3 until Samba3 uses the credentials code in netlogon server Andrew Bartlett

2009-02-13Add VFS ops for Windows BRL: Lock, Unlock and Cancel:Zack Kirsch1-1/+2
This patch adds 3 new VFS OPs for Windows byte range locking: BRL_LOCK_WINDOWS, BRL_UNLOCK_WINDOWS and BRL_CANCEL_WINDOWS. Specifically: * I renamed brl_lock_windows, brl_unlock_windows and brl_lock_cancel to *_default as the default implementations of the VFS ops. * The blocking_lock_record (BLR) is now passed into the brl_lock_windows and brl_cancel_windows paths. The Onefs implementation uses it - future implementations may find it useful too. * Created brl_lock_cancel to do what brl_lock/brl_unlock do: set up a lock_struct and call either the Posix or Windows lock function. These happen to be the same for the default implementation. * Added helper functions: increment_current_lock_count() and decrement_current_lock_count(). * Minor spelling correction in brl_timeout_fn: brl -> blr. * Changed blocking_lock_cancel() to return the BLR that it has cancelled. This allows us to assert its the lock that we wanted to cancel. If this assert ever fires, this path will need to take in the BLR to cancel, rather than choosing on its own. * Adds a small helper function: find_blocking_lock_record_by_id(). Used by the OneFS implementation, but could be useful for others.

2009-02-09S3: New module interface for SMB message statistics gatheringtodd stecher1-1/+4
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.

2009-01-23Extend NTIMES to allow setting create_timetodd stecher1-40/+59
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.
2009-01-15s3: make better use of ccache by not including version.h in every C-file.Michael Adam1-0/+1
version.h changes rather frequently. Since it is included via includes.h, this means each C file will be a cache miss. This applies to the following situations: * When building a new package with a new Samba version * building in a git branch after calling mkversion.sh after a new commit (i.e. virtually always) This patch improves the situation in the following way: * remove inlude "version.h" from includes.h * Use samba_version_string() instead of SAMBA_VERSION_STRING in files that use no other macro from version.h instead of SAMBA_VERSION_STRING. * explicitly include "version.h" in those files that use more macros from "version.h" than just SAMBA_VERSION_STRING.

2008-12-23s3: Fix stream marshalling to return the correct streaminfo statusTim Prouty1-10/+1
When there are enough streams on a file to fill up the max_data_count when responding to a trans2 streaminfo, samba is returning NT_STATUS_BUFFER_TOO_SMALL. Windows handles this by returning NT_STATUS_BUFFER_OVERFLOW while still sending as much of the data that it can fit into the buffer. When the windows client sees BUFFER_OVERFLOW, it retries the streaminfo with a larger buffer (2x). The windows client starts at 2K and will continue increasing the buffer size by two until it reaches 64K. If the streams don't fit in 64K the windows client seems to give up. This patch fixes marshall_stream_info to overfill the buffer by 1 stream so that send_trans2_replies can properly detect the overflow and return the correct status.

2008-12-03s3: Change SMB_VFS_CREATE_FILE to take a create_file_flags argumentTim Prouty1-6/+6
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.
