2009-05-26Introduce "struct stat_ex" as a replacement for SMB_STRUCT_STATVolker Lendecke1-7/+7
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.

delete file This fixes the generic rename/delete problem for 3.3.0 and above. Fixed slightly differently to discussions, user viewable modified ACLs are not a good idea :-). Jeremy.

No functional change, this is a preparation for more current_user ref removal (This used to be commit dcaedf345e62ab74ea87f0a3fa1e3199c75c5445)
2008-06-19Fix checks in can_delete_file_in_directory()Volker Lendecke1-6/+15
With at least NFSv4 ACLs around the write permission for the owner is a bogus check if we can delete a file in a directory. Like in Windows, there are two ways which can grant us such: First, the DELETE permission on the file itself, or if that does not help, the DELETE_CHILD permission on the directory. It might be a bit more code that runs, but essentially we should end up with the same set of syscalls in the non-acl case. (This used to be commit daa9b056645a45edfb3a70e3536011ebe5678970)

This is a security descriptor level function only. Michael (This used to be commit 5931540fa1681f026fed42df387d17e43c493c47)

being (correctly) used in the can_read/can_write checks for hide unreadable/unwritable and this is more properly done using the functions in smbd/file_access.c. Preparing to do NT access checks on all file access. Jeremy. (This used to be commit 6bfb06ad95963ae2acb67c4694a98282d3b29faa)

there as it no longer uses explicit POSIX ACL calls. Jeremy. (This used to be commit ac1eac9b0d07b7b3d341c06ef1a8fd8f3c05a618)
2007-12-19Change the prototype of the vfs function get_nt_acl().Michael Adam1-62/+5
Up to now, get_nt_acl() took a files_struct pointer (fsp) and a file name. All the underlying functions should need and now do need (after the previous preparatory work), is a connection_struct and a file name. The connection_struct is already there in the vfs_handle passed to the vfs functions. So the files_struct argument can be eliminated. This eliminates the need of calling open_file_stat in a couple of places to produce the fsp needed. Michael (This used to be commit b5f600fab53c9d159a958c59795db3ba4a8acc63)
2007-11-13Fix potential orphaned open files.Michael Adam1-2/+4
Calling can_access_file could lead to orphaned open files when SMB_VFS_GET_NT_ACL returned ENOSYS (not implemented). Michael (This used to be commit f4f700cf0c1657c36e801fab20fe7b1a4efcb714)
