2010-12-18Rename vfs operation posix_fallocate to just fallocate and add the ↵Jeremy Allison1-9/+12
vfs_fallocate_mode parameter. It turns out we need the fallocate operations to be able to both allocate and extend filesize, and to allocate and not extend filesize, and posix_fallocate can only do the former. So by defining the vfs op as posix_fallocate we lose the opportunity to use any underlying syscalls (like Linux fallocate) that can do the latter as well. We don't currently use the non-extending filesize call, but now I've changed the vfs op definition we can in the future. For the moment simply map the fallocate op onto posix_fallocate for the VFS_FALLOCATE_EXTEND_SIZE case and return ENOSYS for the VFS_FALLOCATE_KEEP_SIZE case. Jeremy.

2010-07-13Revert "Remove the global char *LastDir."Jeremy Allison1-1/+20
Volker pointed out I'd missed the "last directory" cache part of this code. Return us to caching the directory we're in (reduces sys call load). Mea maxima culpa. Jeremy. This reverts commit 2f30aea3324f32f9b8555e961256fc1280da2871.

2010-03-05Fix for bug #7189 - Open txt files with notepad on samba shares creates problem.Jeremy Allison1-1/+3
Ensure we don't use any of the create_options for Samba private use. Add a new parameter to the VFS_CREATE call (private_flags) which is only used internally. Renumber NTCREATEX_OPTIONS_PRIVATE_DENY_DOS and NTCREATEX_OPTIONS_PRIVATE_DENY_FCB to match the S4 code). Rev. the VFS interface to version 28. Jeremy.

2010-02-11Introduce lp_safe_widelinks()Simo Sorce1-1/+1
This way we avoid any chance that a configuration reload may turn back on wide links when unix extensions are enabled.
2010-02-05Fix bug 7104 - "wide links" and "unix extensions" are incompatible.Jeremy Allison1-1/+1
Change parameter "wide links" to default to "no". Ensure "wide links = no" if "unix extensions = yes" on a share. Fix man pages to refect this. Remove "within share" checks for a UNIX symlink set - even if widelinks = no. The server will not follow that link anyway. Correct DEBUG message in check_reduced_name() to add missing "\n" so it's really clear when a path is being denied as it's outside the enclosing share path. Jeremy.

2009-09-24vfs catia: Fix the double translation that was happening with createfile and ↵Aravind Srinivasan1-3/+5
open. Since the catia translation is implemented for open, it should not also be done in createfile. By removing createfile from catia, translation is now done correctly for the primary open path. In order to support systems that have custom createfile implementations that don't eventually call SMB_VFS_OPEN, SMB_VFS_TRANSLATE_NAME has been expanded to take an additional argument that specifies direction.

2009-08-28s3: Add a new VFS op called SMB_VFS_TRANSLATE_NAMEAravind Srinivasan1-2/+19
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 Prouty1-72/+38
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.
2009-06-10s3: Prepare the first set of SMB_VFS_CREATE_FILE callers to take an ↵Tim Prouty1-8/+18
smb_filename struct Some of the callers required minimal changes, while others (copy_internals) required significant changes. The task is simplified a little bit because we are able to do operations and checks on the base_name when a stream isn't used. This patch should cause no functional changes. Volker, Jeremy: Please check
2009-06-02Add SMB_VFS_CONNECTPATH operationVolker Lendecke1-8/+22
This is required for the shadow_copy2 module and "wide links = no". The file system snapshots by nature are typically outside of share directory. So the REALPATH result fails the wide links = no test.
2009-06-02Remove a variable used just onceVolker Lendecke1-2/+3
2009-05-26Introduce "struct stat_ex" as a replacement for SMB_STRUCT_STATVolker Lendecke1-14/+14
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.
