commit da80659d4aa758dc6935b10ec64513f0b67bc969 upstream.

cifs: Fix check for regular file in couldbe_mf_symlink()

2014-01-31T15:06:43Z

MF Symlinks are regular files containing content in a specified format. The function couldbe_mf_symlink() checks the mode for a set S_IFREG bit as a test to confirm that it is a regular file. This bit is also set for other filetypes and simply checking for this bit being set may return false positives. We ensure that we are actually checking for a regular file by using the S_ISREG macro to test instead.

Unix extensions rigth now are only applicable to smb1 operations. Move the check and subsequent unix extension call to the smb1 specific call to query_symlink() ie. cifs_query_symlink(). Signed-off-by: Sachin Prabhu Reviewed-by: Jeff Layton Signed-off-by: Steve French

cifs: Add create MFSymlinks to protocol ops struct

2014-01-20T06:14:00Z

Add a new protocol ops function create_mf_symlink and have create_mf_symlink() use it. This patchset moves the MFSymlink operations completely to the ops structure so that we only use the right protocol versions when querying or creating MFSymlinks.

cifs: Rename and cleanup open_query_close_cifs_symlink()

2014-01-20T06:13:51Z

Rename open_query_close_cifs_symlink to cifs_query_mf_symlink() to make the name more consistent with other protocol version specific functions. We also pass tcon as an argument to the function. This is already available in the calling functions and we can avoid having to make an unnecessary lookup. Signed-off-by: Sachin Prabhu Reviewed-by: Jeff Layton Signed-off-by: Steve French
