2011-07-20s3-auth Use *unix_token rather than utok in struct auth3_session_infoAndrew Bartlett1-4/+4
This brings this structure one step closer to the struct auth_session_info. A few SMB_ASSERT calls are added in some key places to ensure that this pointer is initialised, to make tracing any bugs here easier in future. NOTE: Many of the users of this structure should be reviewed, as unix and NT access checks are mixed in a way that should just be done using the NT ACL. This patch has not changed this behaviour however. Andrew Bartlett Signed-off-by: Andrew Tridgell <tridge@samba.org>

2011-02-22s3-auth Rename auth_serversupplied_info varaiables: server_info -> session_infoAndrew Bartlett1-4/+4
These variables, of type struct auth_serversupplied_info were poorly named when added into 2001, and in good consistant practice, this has extended all over the codebase in the years since. The structure is also not ideal for it's current purpose. Originally intended to convey the results of the authentication modules, it really describes all the essential attributes of a session. This rename will reduce the volume of a future patch to replaced these with a struct auth_session_info, with auth_serversupplied_info confined to the lower levels of the auth subsystem, and then eliminated. (The new structure will be the output of create_local_token(), and the change in struct definition will ensure that this is always run, populating local groups and privileges).

2009-06-24s3: Plumb smb_filename through SMB_VFS_STAT and SMB_VFS_LSTATTim Prouty1-7/+8
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.
2009-05-26Introduce "struct stat_ex" as a replacement for SMB_STRUCT_STATVolker Lendecke1-10/+10
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.

2002-12-30Add a new VFS module, that just fiddles the file permissions. Still need toAndrew Bartlett1-0/+471
make it fiddle with NT ACLs (or report no ACL, so Samba fakes it up). The idea here is that Samba reports an NT ACL to Windows clients, which use that ACL in downloaded profiles. If the user doesn't have write permissions on the directories being downloaded, then it cant put the subfolders in (yes, NT will set perms so that it can't access the dir as the user the created it) and the profile download fails. The current solution it to give the user unix write perms to the folders, but this is rather dangerous - sombody could trojen the profile. This should avoid that mess. I'll test this out properly next week, but it works in vfstest (thanks idra!). Andrew Bartlett (This used to be commit 1ad782282a3eb4f89c489a77ad8404099d41d0f9)
