2009-11-18s3: Do not talloc in readdirVolker Lendecke1-30/+51
This is a hot codepath (called from the stat cache)
2009-08-28s3: Add a new VFS op called SMB_VFS_TRANSLATE_NAMEAravind Srinivasan1-13/+22
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.

2009-06-24s3: Plumb smb_filename through SMB_VFS_STAT and SMB_VFS_LSTATTim Prouty1-27/+79
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.
2009-06-24s3: Convert is_visible_file to use talloc_asprintf instead of mallocTim Prouty1-14/+15
2009-05-26Introduce "struct stat_ex" as a replacement for SMB_STRUCT_STATVolker Lendecke1-6/+6
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.
2009-05-18s3: Always allocate memory in dptr_ReadDirNameAravind Srinivasan1-13/+26
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>
2009-05-05s3: Fix trans2 path to use case-insensitive stat optimizationtprouty1-0/+17
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.

search requests. By default this VFS call is a NOOP, but the onefs vfs module takes advantage of it to initialize direntry search caches at the beginning of each TRANS2_FIND_FIRST, TRANS2_FIND_NEXT, SMBffirst, SMBsearch, and SMBunique

2008-04-07smbd: implement the strange write time update logicStefan Metzmacher1-0/+8
We now never call file_ntimes() directly, every update is done via smb_set_file_time(). This let samba3 pass the BASE-DELAYWRITE test. The write time is only updated 2 seconds after the first write() on any open handle to the current time (not the time of the first write). Each handle which had write requests updates the write time to the current time on close(). If the write time is set explicit via setfileinfo or setpathinfo the write time is visible directly and a following close on the same handle doesn't update the write time. metze (This used to be commit 2eab212ea2e1bfd8fa716c2c89b2c042f7ba12ea)

Allow us to correctly refuse to set delete on close on a non-empty directory. There are still some delete-on-close wrinkles to be fixed, but I understand how to do that better now. I'll fix this tomorrow. Jeremy. (This used to be commit 029635885825a5562e7974a6f5675cce3bf1b5dc)
2007-10-10r20844: Somewhat radical change - this may break the build (I willJeremy Allison1-12/+19
watch carefully - so I'm doing it in one transaction so I can roll back). Change check_name(), reduce_name() and dptr_create() to return NTSTATUS. This helps a lot in error path processing and especially in reduce_name() allows us to ditch the flaky and error-prone saving of errno and return errors directly. Jeremy.

2007-10-10r16537: Fix for bug #3858, all files in a directory notJeremy Allison1-6/+7
being deleted when hide unreadable set to true. Here's the scoop. This one is really interesting. The pattern of deleting a directory is to do a findfirst to get the first part of the list, then for each name returned it does a open/set delete on close/close -> thus deleting the file. Then it does a findnext with the last file name THAT IT JUST DELETED ! Now we can handle this in the findnext in the case where hide unreadable is set to false as we look back in our cache of names and just seek to the right point. The bug is actually fixed in the first hunk of this patch - the one that removes the is_visible_file() check after SearchDir returns false. We don't actually need it and in this case it's causing the delete to be aborted because it can't find the name (doh ! it was just deleted). We don't need it as SearchDir is only ever called from findnext, and findnext should only ever be returning names we gave it. The rest of the patch are the debugs I used to find the problem but they're generically useful. Phew - that one took a while to track down..... Jerry, please merge for 3.0.23 final. Jeremy.
