gpfs.so: map the file_inherit and dir_inherit flags away for files

2009-08-14T21:23:20+00:00

GPFS sets inherits dir_inhert and file_inherit flags
to files, too, which confuses windows, and seems to
be wrong anyways.

So when mapping a nfs4 acl to a windows acl, we map these
flags away for files.

do not merge ACEs with different SMB_ACE4_INHERIT_ONLY_ACE flag, this leads to wrong inheritance flags in the ACL e.g. (on GPFS) user:10000036:rwxc:allow (X)READ/LIST (X)WRITE/CREATE (X)MKDIR (X)SYNCHRONIZE (X)READ_ACL (X)READ_ATTR (X)READ_NAMED (X)DELETE (X)DELETE_CHILD (X)CHOWN (X)EXEC/SEARCH (X)WRITE_ACL (X)WRITE_ATTR (X)WRITE_NAMED

 (X)DELETE    (X)DELETE_CHILD (X)CHOWN (X)EXEC/SEARCH (X)WRITE_ACL (X)WRITE_ATTR (X)WRITE_NAMED

would be merged to

user:10000036:rwxc:allow:FileInherit:DirInherit:InheritOnly
 (X)READ/LIST (X)WRITE/CREATE (X)MKDIR (X)SYNCHRONIZE (X)READ_ACL  (X)READ_ATTR  (X)READ_NAMED
 (X)DELETE    (X)DELETE_CHILD (X)CHOWN (X)EXEC/SEARCH (X)WRITE_ACL (X)WRITE_ATTR (X)WRITE_NAMED

group:10000005:rwxc:allow:FileInherit:DirInherit:InheritOnly
 (X)READ/LIST (X)WRITE/CREATE (X)MKDIR (X)SYNCHRONIZE (X)READ_ACL  (X)READ_ATTR  (X)READ_NAMED
 (X)DELETE    (X)DELETE_CHILD (X)CHOWN (X)EXEC/SEARCH (X)WRITE_ACL (X)WRITE_ATTR (X)WRITE_NAMED

so the explicit right for the user on the parent directory will be gone (the InheritOnly flag only accounts to subdirectories)
thus leaving the user without access to the directory itself

s3: Plumb smb_filename through SMB_VFS_STAT and SMB_VFS_LSTAT

2009-06-25T04:15:25+00:00

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.

Introduce "struct stat_ex" as a replacement for SMB_STRUCT_STAT

2009-05-26T15:48:23+00:00

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.
